If the Reorganization is approved by the Positive Change Fund’s shareholders at the Special Meeting, shareholders of the Positive Change Fund will receive shares of the Vanguard Fund having the same aggregate net asset value as the shares of the Positive Change Fund they hold on the date of the Reorganization. The Reorganization will not affect the total value of any shareholders’ holdings in the Positive Change Fund at the time of the Reorganization. If shareholders approve the Reorganization, shortly after the approval the Positive Change Fund’s distributor expects to cease accepting subscriptions by new and existing shareholders until the completion of the Reorganization. Positive Change Fund shareholders will continue to be able to redeem their shares up until the completion of the Reorganization. Subsciption and redemption requests received after completion of the Reorganization (if approved) should be directed to the Vanguard Fund in accordance with its prospectus. The foregoing is not an offer to sell, nor a solicitation of an offer to buy, shares of the Vanguard Fund or Positive Change Fund, nor is it a solicitation of any proxy.

time to time.

Effective immediately:

1. The following sentence is added after the sentence that begins with “The Fund aims to hold securities for …” in the section titled “Principal Investment Strategies” in each Equity Fund’s Prospectus:

Further to the Fund’s long-term investment approach, the portfolio managers seek to identify companies with the potential to grow sustainably. When assessing a company’s ability to deliver sustainable growth over the long term, Baillie Gifford Overseas Limited (the “Manager”) considers a range of factors, including the environmental, social and governance characteristics of a company.

2. The first paragraph of the section titled “Principal Investment Risks—Long-Term Investment Strategy Risk” in the Equity Funds Prospectus is replaced with the following:

The Funds pursue a long-term investment approach, typically seeking returns over a period of several years, which can comprise a full market cycle or more. This investment style may cause a Fund to lose money or underperform compared to its benchmark index or other mutual funds over extended periods of time, and a Fund may not perform as expected in the long term. The market price of a Fund’s investments will fluctuate daily due to economic and other events that affect particular companies and other issuers or the market as a whole, and the market may disagree with the Manager’s assessment for growth in the shorter- or longer-terms. Short- and medium-term price fluctuations may be especially pronounced in less developed markets or in companies with lower market capitalizations. A Fund that integrates ESG factors into its long-term investment approach is also subject to the risks described above.

Fund Summaries

Baillie Gifford Asia Ex Japan Fund

Investment ObjectiveBaillie Gifford Asia Ex Japan Fund seeks capital appreciation.

Fees and ExpensesThe tables below describe the fees and expenses that you maypay if you buy, hold, and sell shares of the Fund. You may payother fees, such as brokerage commissions and other fees tofinancial intermediaries, which are not reflected in the tables andexamples below.

Shareholder Fees(Fees paid directly from your investment)

Class K Institutional ClassNone None

Annual Fund Operating Expenses(Expenses that you pay each year as a percentage of the valueof your investment)

Class K Institutional ClassManagement Fees(a) 0.65% 0.65%Distribution (12b-1) Fees None NoneOther Expenses(b) 16.90% 17.05%Total Annual Fund Operating Expenses 17.55% 17.70%Fee Waiver and/or Expense Reimbursement(c) (16.75)% (16.75)%Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement(c) 0.80% 0.95%

(a) The Management Fee consists of an Advisory Fee and anAdministration and Supervisory Fee paid by the Fund to BaillieGifford Overseas Limited.

(b) Class K and Institutional Class were unfunded as of December 31,2020. Therefore Other Expenses have been estimated for thecurrent fiscal year assuming Fund assets of $1 million.

(c) Baillie Gifford Overseas Limited has contractually agreed to waiveits fees and/or bear Other Expenses of the Fund until April 30, 2022to the extent that such Fund’s Total Annual Operating Expenses(excluding taxes, sub-accounting expenses, and extraordinaryexpenses) exceed 0.80% for Class K and Institutional Class shares.This contractual agreement may only be terminated by the Board ofTrustees of the Trust. Expenses after waiver/reimbursementexceed 0.80% for Institutional Class due to estimated sub-accounting expenses of 0.15%.

Example of ExpensesThe example below is intended to help you compare the cost ofinvesting in the Fund with the cost of investing in other mutualfunds. It assumes that you invest $10,000 in the Fund for the timeperiods indicated, regardless of whether or not you redeem yourshares at the end of such periods. It also assumes that yourinvestment has a 5% return each year and that the Fund’soperating expenses remain the same. The example below alsoapplies any contractual expense waivers and/or expensereimbursements to the first year of each period listed in the table.

Although your actual costs may be higher or lower, based onthese assumptions, your expenses would be:

Class K Institutional Class1 Year $82 $973 Years $3,294 $3,327

Portfolio TurnoverThe Fund pays transaction costs, such as commissions, when itbuys and sells securities (or “turns over” its portfolio). A higherportfolio turnover rate may indicate higher transaction costs andmay result in higher taxes when Fund shares are held in ataxable account. These transaction costs, which are not reflectedin “Annual Fund Operating Expenses” or in the “Example ofExpenses” above, affect the Fund’s performance. Because theFund has not commenced operations, it does not have a portfolioturnover rate.

Principal Investment StrategiesThe Fund seeks to meet its objective by investing in a portfolio ofcommon stocks and other equity securities of issuers located inAsia (excluding Japan) and including the Indian subcontinent.

Under normal circumstances, the Fund will invest at least 80% ofits net assets (plus any borrowings for investment purposes) insecurities of companies located in countries represented in theMSCI All Country Asia Ex Japan Index. The MSCI All CountryAsia Ex Japan Index includes large-cap, mid-cap, and small-capissuers from a variety of countries including China, Hong Kong,India, Indonesia, Malaysia, the Philippines, Singapore, SouthKorea, Taiwan, and Thailand. The economies of many of thesecountries are considered emerging market economies, and somemay be considered frontier markets. The Fund will invest in equitysecurities either directly or indirectly, such as through depositaryreceipts, and may invest in preferred stocks, convertiblesecurities and warrants. The Fund is not constrained with respectto market capitalization and may participate in initial publicofferings (“IPOs”) and in securities offerings that are notregistered in the U.S.

The portfolio managers employ a bottom-up approach to stockselection and select companies without being constrained by theMSCI All Country Asia Ex Japan benchmark. The portfoliomanagers focus on company research and the long-term outlookof companies and industries. Ideas can come from a wide varietyof sources, including, but not limited to, research trips, companymeetings, and relationships with industry thought leaders andacademic institutions. Stock ideas are normally researched toassess a range of factors, including: long-term growth potential,geographic and industry positioning, competitive advantage,management, financial strength and valuation. The intendedoutcome is a diversified portfolio of between 50 and 100 growthcompanies with the potential to outperform the benchmark overthe long term. The Fund aims to hold securities for relatively longperiods, which results in relatively low portfolio turnover and is inline with the Fund’s long-term investment outlook.

The Fund may invest without limitation in securities quoted ordenominated in currencies other than the U.S. dollar and mayhold such currencies. The Fund does not expect to engage in

currency hedging and thus expects to be fully exposed tocurrency fluctuations relative to the U.S. dollar.

Principal RisksThe Fund’s net asset value and returns will be impacted by theperformance of the underlying investments of the Fund. Aninvestment in the Fund is not a deposit in a bank and is notinsured or guaranteed by the Federal Deposit InsuranceCorporation or any other government agency. You could losemoney by investing in the Fund.

The principal risks of investing in the Fund (in alphabetical orderafter the first five risks) are:

— Investment Style Risk – Baillie Gifford Overseas Limited (the“Manager”) actively makes investment decisions for the Fundthrough bottom-up stock selection. Accordingly, the Fund willhave risk characteristics that differ from its benchmark index.The Manager’s judgments about the attractiveness, relativevalue, or potential appreciation of a particular stock mayprove to be incorrect and cause the Fund to lose money orunderperform compared to its benchmark index. There can beno assurance that the Manager’s investment decisions willproduce the desired results.

— Growth Stock Risk – The prices of growth stocks may bebased largely on expectations of future earnings, and theirprices can decline rapidly and significantly in reaction tonegative news. Growth stocks may underperform stocks inother broad style categories (and the stock market as awhole) over any period of time and may shift in and out offavor with investors generally, sometimes rapidly, dependingon changes in market, economic, and other factors.

— Long-Term Investment Strategy Risk – The Fund pursues along-term investment approach, typically seeking returnsover a period of several years. This investment style maycause the Fund to lose money or underperform compared toits benchmark index or other mutual funds over extendedperiods of time, and the Fund may not perform as expectedin the long term. An investment in the Fund may be moresuitable for long-term investors who can bear the risk ofshort- or medium-term fluctuations in the value of the Fund’sportfolio.

— Geographic Focus Risk – The Fund expects to focus itsinvestments in a limited number of countries or geographicregions, and as a result may not offer the same level ofdiversification of risks as a more broadly global fundbecause the Fund will be exposed to a smaller geographicarea. The performance of a fund that is less diversifiedacross countries or geographic regions will be closely tied tomarket, currency, economic, political, environmental, orregulatory conditions and developments in the countries orregions in which the fund invests, and may be more volatilethan the performance of a more geographically-diversifiedportfolio.

— Asia Risk – Investing in securities of companies located in orwith exposure to Asian countries involves certain risks andconsiderations not typically associated with investing insecurities of U.S. issuers, including different financialreporting standards, currency exchange rate fluctuations,

and highly regulated markets with the potential forgovernment interference. The economies of many Asiancountries are heavily dependent on international trade andon only a few industries or commodities and, as a result, canbe adversely affected by trade barriers, exchange controlsand other measures imposed or negotiated by the countrieswith which they trade. Some Asian securities may be lessliquid than U.S. or other foreign securities. See “China Risk”for additional details regarding the risks of investing in thatcountry.

Additionally, many of the economies of countries in Asia areconsidered emerging market or frontier market economies.These Asian economies are often characterized by highinflation, undeveloped financial service sectors, frequentcurrency fluctuations, devaluations, or restrictions, politicaland social instability, and less efficient markets. See“Emerging Markets Risk” and “Frontier Markets Risk” foradditional details regarding the risks of investing in suchcountries.

— China Risk – Investing in securities of Chinese issuersinvolves certain risks and considerations not typicallyassociated with investing in securities of U.S. issuers,including, among others, more frequent trading suspensionsand government interventions (including by nationalization ofassets), currency exchange rate fluctuations or blockages,limits on the use of brokers and on foreign ownership,different financial reporting standards, higher dependence onexports and international trade, potential for increased tradetariffs, sanctions, embargoes and other trade limitations, andcustody risks. U.S. sanctions or other investment restrictionscould preclude the Fund from investing in certain Chineseissuers or cause the Fund to sell investments at adisadvantageous time. Significant portions of the Chinesesecurities markets may become rapidly illiquid, as Chineseissuers have the ability to suspend the trading of their equitysecurities, and have shown a willingness to exercise thatoption in response to market volatility and other events.

— Conflicts of Interest Risk – The Manager’s relationships withthe Fund’s institutional investor base may give rise to variousconflicts of interest, since the Manager will sometimes havean incentive to favor those shareholders over othershareholders in the Fund. In addition, the Manager serves asinvestment adviser to various clients other than the Fund,some of whom may pursue strategies that are substantiallysimilar or nearly identical to investment strategies pursuedby the Fund. This “side-by-side” management may give riseto various conflicts of interest, including, for example, inconnection with the fair allocation of trades among theManager’s clients or the sharing of different, more, or moretimely information regarding investment performance,portfolio holdings, strategy developments and/or theManager’s general market outlook. Furthermore, ifinvestment personnel of the Manager hold board or otherpositions at outside companies, they could be exposed tomaterial non-public information potentially impeding ordelaying a Fund’s ability to buy or sell certain investments, orthey could otherwise be restricted in their ability toparticipate in a Fund’s investment process.

Baillie Gifford Funds – Prospectus

— Currency Risk – The Fund may realize a loss if it hasexposure to a non-U.S. currency, and this non-U.S. currencydeclines in value, relative to the U.S. dollar. The Fund doesnot expect to engage in currency hedging and thus expectsto be fully exposed to currency fluctuations relative to theU.S. dollar.

— Emerging Markets Risk – To the extent the Fund invests inemerging market securities, the Fund may be exposed togreater market, credit, currency, liquidity, legal, political,technical and other risks different from, or greater than, therisks of investing in developed markets.

— Equity Securities Risk – Equity securities may react morestrongly to changes in an issuer’s financial condition orprospects than other securities of the same issuer. Investing inequity securities indirectly, such as through participatory notesor depositary receipts, may involve other risks such as the riskthat the counterparty may default or that the investment doesnot track the underlying security as expected.

— Focused Investment Risk – Should the Fund focus itsinvestments in related, or a limited number of, countries,regions, sectors, or companies, this would create more riskand greater volatility than if the Fund’s investments wereless focused.

— Frontier Markets Risk – Frontier markets are those emergingmarkets that are considered to be among the smallest, leastmature and least liquid and, as a result, may be more volatileand less liquid than investments in more developed marketsor in other emerging market countries. Emerging marketsrisk may be especially heightened in frontier markets.

— Government and Regulatory Risk – Governmental andregulatory authorities in the United States and othercountries, have taken, and may in the future take, actionsintervening in the markets in which the Fund invests and inthe economy more generally. Governmental and regulatoryauthorities may also act to increase the scope or burden ofregulations applicable to the Fund or to the companies inwhich the Fund invests. The effects of these actions on themarkets generally, and Fund’s investment program inparticular, can be uncertain and could restrict the ability ofthe Fund to fully implement its investment strategies, eithergenerally, or with respect to certain securities, industries, orcountries. By contrast, markets in some non-U.S. countrieshistorically have been subject to little regulation or oversightby governmental or regulatory authorities, which couldheighten the risk of loss due to fraud or market failures inthose countries. Governments, agencies, or other regulatorybodies in any country may adopt or change laws orregulations that could adversely affect the Fund or themarket value of an instrument held by the Fund.

— Information Technology Risk – Cyber-attacks, disruptions, orfailures that affect the Fund’s service providers, counterparties,the securities markets generally, other market participants, orissuers of securities held by the Fund may adversely affect theFund and its shareholders, including by causing losses for theFund or impairing Fund operations.

— IPO Risk – The Fund may purchase securities in IPOs.These securities are subject to many of the same risks of

investing in companies with smaller market capitalizations.Securities issued in IPOs have no trading history, andinformation about the companies may be available for verylimited periods. In addition, the prices of securities sold inIPOs may be highly volatile.

— Large-Capitalization Securities Risk – Returns oninvestments in securities of large companies could trail thereturns on investments in securities of smaller and medium-sized companies. Larger companies may be unable torespond as quickly as smaller and medium-sized companiesto competitive challenges or to changes in business, product,financial, or other market conditions. Larger companies maynot be able to achieve or maintain growth at the high ratesthat may be achieved by well-managed smaller and medium-sized companies.

— Liquidity Risk – The Fund’s investments may be subject tolow trading volume, lack of a market maker, contractual lock-in periods or regulatory restrictions, and the Fund may holdlarge positions in particular securities. As a result, it may notbe possible to sell an investment at a particular time or at anacceptable price. Liquidity risk may be magnified duringperiods of changing interest rates, significant shareholderredemptions or market turmoil. Illiquid securities may tradeat a discount from comparable, more liquid investments andmay be subject to wide fluctuations in market value. In somecases, due to unanticipated levels of illiquidity the Fund mayseek to meet its redemption obligations wholly or in part bydistributions of assets in-kind.

— Market Disruption and Geopolitical Risk – The value of theFund’s investments could be adversely affected by eventsthat disrupt securities markets and adversely affect globalmarkets such as war, terrorism, public health crises, andgeopolitical events and by changes in non-U.S. and U.S.economic and political conditions. As a result of theseevents, the Fund could lose money, experience significantredemptions, encounter operational difficulties, and sufferother negative impacts.

— Market Risk – The value of the Fund’s investments will beaffected by fluctuations in the stock markets in which theFund is invested, factors affecting a particular industry orindustries, real or perceived adverse economic conditions,changes in interest or currency rates or adverse investorsentiment generally. Declines in securities market prices mayreduce the net asset value of the Fund’s shares.

— New and Smaller-Sized Funds Risk – New funds andsmaller-sized funds will be subject to greater liquidity riskdue to their smaller asset bases and may be required to sellsecurities at disadvantageous times or prices due to a largeshareholder redemption. A fund that has been recentlyformed will have limited or no performance history forinvestors to evaluate and may not reach or maintain asufficient asset size to effectively implement its investmentstrategy.

— Non-U.S. Investment Risk – Non-U.S. securities are subjectto additional risks, including less liquidity, increased volatility,less transparency, withholding or other taxes, increasedvulnerability to adverse changes in local and globaleconomic conditions, less regulation, and possible

fluctuation in value due to adverse political conditions.Foreign portfolio transactions generally involve highercommission rates, transfer taxes, and custodial costs thansimilar transactions in the U.S.

— Service Provider Risk – The Fund will be affected by theManager’s investment techniques, analyses, assessmentsand employee retention. Similarly, adverse events orperformance failures at a service provider, such as humanerror, inadequate controls or insolvency, have the ability toadversely affect the Fund.

— Settlement Risk – The Fund may experience delays insettlement due to the different clearance and settlementprocedures in non-U.S. countries. Such delays may increasecredit risk to the Fund, limit the ability of the Fund to reinvestthe proceeds of a sale of securities, or prevent the Fundfrom selling securities at times and prices it considersdesirable.

— Small- and Medium-Capitalization Securities Risk – Securitiesof small- and medium-capitalization companies can be morevolatile due to various factors including more limited productlines, financial and management resources and marketdistribution channels, as well as shorter operating historiesand potentially reduced liquidity, especially during marketdeclines, than the securities of larger, more establishedcompanies.

— Valuation Risk – In certain circumstances, some of theFund’s portfolio holdings may be valued on the basis offactors other than market quotations by employing the fairvalue procedures adopted by the Board of Trustees of theTrust (the “Board”). This may occur more often in times ofmarket turmoil or reduced liquidity. Portfolio holdings that arevalued using techniques other than market quotations,including “fair valued” securities, may be subject to greaterfluctuation in their valuations from one day to the next than ifmarket quotations were used. There is no assurance that theFund could sell or close out a portfolio position for the valueestablished for it at any time, and it is possible that the Fundwould incur a loss because a portfolio position is sold orclosed out at a discount to the valuation established by theFund at that time.

PerformanceThe Fund had not commenced operations as of December 31,2020. Accordingly, performance data is not included. Whenperformance data becomes available, it will be posted to thefollowing website: http://USmutualfund.bailliegifford.com.

Baillie Gifford China A Shares Growth Fund

Prior to April 30, 2021, the Fund was known as Baillie GiffordChina A Shares Fund.

Investment ObjectiveBaillie Gifford China A Shares Growth Fund seeks capitalappreciation.

Fees and ExpensesThe tables below describe the fees and expenses that you maypay if you buy, hold, and sell shares of the Fund. You may payother fees, such as brokerage commissions and other fees tofinancial intermediaries, which are not reflected in the tables andexamples below.

Shareholder Fees(Fees paid directly from your investment)

Class K Institutional ClassNone None

Annual Fund Operating Expenses(Expenses that you pay each year as a percentage of the valueof your investment)

Class K Institutional ClassManagement Fees(a) 0.72% 0.72%Distribution (12b-1) Fees None NoneOther Expenses(b) 9.80% 9.80%Total Annual Fund Operating Expenses 10.52% 10.52%Fee Waiver and/or Expense Reimbursement(c) (9.65)% (9.65)%Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement(c) 0.87% 0.87%

(a) The Management Fee consists of an Advisory Fee and anAdministration and Supervisory Fee paid by the Fund to BaillieGifford Overseas Limited.

(b) While Other Expenses for the last fiscal year were the same forInstitutional Class and Class K, Other Expenses for InstitutionalClass are expected to be higher than those of Class K in the future,since Institutional Class is expected to bear sub-accountingexpenses.

(c) Baillie Gifford Overseas Limited has contractually agreed to waiveits fees and/or bear Other Expenses of the Fund until April 30, 2022to the extent that the Fund’s Total Annual Fund OperatingExpenses (excluding taxes, sub-accounting expenses andextraordinary expenses) exceed 0.87% for Class K and InstitutionalClass shares. This contractual agreement may only be terminatedby the Board of Trustees of the Trust. Because this cap of 0.87%excludes sub-accounting expenses, Total Annual Fund OperatingExpenses After Fee Waiver and/or Expense Reimbursement forInstitutional Class are expected to exceed the cap in the future.

Example of ExpensesThe example below is intended to help you compare the cost ofinvesting in the Fund with the cost of investing in other mutualfunds. It assumes that you invest $10,000 in the Fund for the timeperiods indicated, regardless of whether or not you redeem yourshares at the end of such periods. It also assumes that yourinvestment has a 5% return each year and that the Fund’soperating expenses remain the same. The example below also

applies any contractual expense waivers and/or expensereimbursements to the first year of each period listed in the table.

Although your actual costs may be higher or lower, based onthese assumptions, your expenses would be:

Class K Institutional Class1 Year $89 $893 Years $2,160 $2,1605 Years $4,010 $4,01010 Years $7,810 $7,810

Portfolio TurnoverThe Fund pays transaction costs, such as commissions, when itbuys and sells securities (or “turns over” its portfolio). A higherportfolio turnover rate may indicate higher transaction costs andmay result in higher taxes when Fund shares are held in ataxable account. These transaction costs, which are not reflectedin “Annual Fund Operating Expenses” or in the “Example ofExpenses” above, affect the Fund’s performance. During theFund’s most recent fiscal year, the Fund’s portfolio turnover ratewas 20% of the average value of its portfolio.

Principal Investment StrategiesThe Fund seeks to meet its objective by investing in a portfolio ofcommon stocks and other equity securities of issuers located inthe People’s Republic of China (“China”).

Under normal circumstances, the Fund will invest at least 80% ofits net assets (plus any borrowings for investment purposes) inChina “A” shares (“A Shares” or “China A Shares”). China AShares are common stocks and other equity securities of issuerslocated in China that are listed or traded on the Shanghai StockExchange, the Shenzhen Stock Exchange, or any other stockexchange in China and which are quoted in renminbi (“RMB”).The Fund expects to access China A Shares through theShanghai-Hong Kong Stock Connect program and theShenzhen-Hong Kong Stock Connect program (together the“Stock Connect programs”). The Fund also may, in the future,access China A Shares through the qualified foreign investorprogram (“QFI” formerly the Qualified Foreign InstitutionalInvestor and Renminbi Qualified Foreign Institutional Investorprograms) or other means of access which may becomeavailable in the future. The foregoing channels are intended toallow the Fund to invest in China A Shares directly. In addition,the Fund may invest in equity securities indirectly, such asthrough depositary receipts or exchange traded funds (“ETFs”),especially during extended closures of the Chinese markets.

The Fund may also invest in preferred stocks, convertiblesecurities and warrants. The Fund may invest in any sector orindustry, in issuers of any market capitalization, and mayparticipate in initial public offerings (“IPOs”) and in securitiesofferings that are not registered in the U.S.

The portfolio managers employ a bottom-up approach to stockselection and select companies without being constrained by theFund’s benchmark, the MSCI China A Onshore Index. Theportfolio managers focus on company research and the long-term outlook of companies and industries. Ideas can come froma wide variety of sources, including, but not limited to, researchtrips, company meetings, and relationships with industry thought

leaders and academic institutions. Stock ideas are normallyresearched to assess a range of factors, including: long-termgrowth potential, geographic and industry positioning, competitiveadvantage, management, financial strength and valuation. Theportfolio managers employ an additional due diligence processfor Chinese companies in light of the comparative immaturity ofthe Chinese capital markets and the status of China as anemerging market economy.

The portfolio managers seek to identify exceptional growthcompanies in China and hold them for long enough that theadvantages of their business models and the strength of theircorporate cultures become dominant drivers of their stock price.The intended outcome is a non-diversified portfolio of between25 and 40 growth companies with the potential to outperform thebenchmark over the long term. The Fund intends to operate as anon-diversified fund, which means that it may invest a relativelylarge percentage of its assets in a small number of issuers,industries, or sectors. The Fund aims to hold securities for longperiods (typically 5-10 years), which is expected to result in arelatively low portfolio turnover and is in line with the Fund’s long-term investment outlook.

The Fund may invest without limitation in securities quoted ordenominated in currencies other than the U.S. dollar and mayhold such currencies. The Fund does not expect to engage incurrency hedging and thus expects to be fully exposed tocurrency fluctuations relative to the U.S. dollar.

Principal RisksThe Fund’s net asset value and returns will be impacted by theperformance of the underlying investments of the Fund.

— China Risk – Investing in securities of Chinese issuersinvolves certain risks and considerations not typicallyassociated with investing in securities of U.S. issuers,including, among others, more frequent trading suspensionsand government interventions (including by nationalization ofassets), currency exchange rate fluctuations or blockages,limits on the use of brokers and on foreign ownership,different financial reporting standards, higher dependence onexports and international trade, potential for increased tradetariffs, sanctions, embargoes and other trade limitations,custody risks, and potential adverse tax consequences. U.S.sanctions or other investment restrictions could preclude theFund from investing in certain Chinese issuers or cause theFund to sell investments at a disadvantageous time.Significant portions of the Chinese securities markets maybecome rapidly illiquid, as Chinese issuers have the ability tosuspend the trading of their equity securities, and haveshown a willingness to exercise that option in response tomarket volatility and other events.

— Investment Style Risk – Baillie Gifford Overseas Limited(the “Manager”) actively makes investment decisions for theFund through bottom-up stock selection. Accordingly, the

Fund will have risk characteristics that differ from itsbenchmark index. The Manager’s judgments about theattractiveness, relative value, or potential appreciation of aparticular stock may prove to be incorrect and cause theFund to lose money or underperform compared to itsbenchmark index. There can be no assurance that theManager’s investment decisions will produce the desiredresults.

— Growth Stock Risk – The prices of growth stocks may bebased largely on expectations of future earnings, and theirprices can decline rapidly and significantly in reaction tonegative news. Growth stocks may underperform stocks inother broad style categories (and the stock market as awhole) over any period of time and may shift in and out offavor with investors generally, sometimes rapidly, dependingon changes in market, economic, and other factors.

— Long-Term Investment Strategy Risk – The Fund pursues along-term investment approach, typically seeking returnsover a period of several years. This investment style maycause the Fund to lose money or underperform compared toits benchmark index or other mutual funds over extendedperiods of time, and the Fund may not perform as expectedin the long term. An investment in the Fund may be moresuitable for long-term investors who can bear the risk ofshort- or medium-term fluctuations in the value of the Fund’sportfolio.

— Non-Diversification Risk – The Fund is classified as a “non-diversified” fund. A non-diversified fund may hold a smallernumber of portfolio securities, with larger positions in eachsecurity it holds, than many other mutual funds. To the extentthe Fund invests in a relatively small number of issuers, adecline in the market value of a particular security held bythe Fund may affect its value more than if it invested in alarger number of issuers. The value of the Fund’s sharesmay be more volatile than the values of shares of morediversified funds. See also “Focused Investment Risk.”

— Geographic Focus Risk – The Fund expects to focus itsinvestments in a limited number of countries or geographicregions, and as a result may not offer the same level ofdiversification of risks as a more broadly global fundbecause the Fund will be exposed to a smaller geographicarea. The performance of a fund that is less diversifiedacross countries or geographic regions will be closely tied tomarket, currency, economic, political, environmental, orregulatory conditions and developments in the countries orregions in which the fund invests, and may be more volatilethan the performance of a more geographically-diversifiedportfolio.

— Conflicts of Interest Risk – The Manager’s relationships withthe Fund’s institutional investor base may give rise to variousconflicts of interest, since the Manager will sometimes havean incentive to favor those shareholders over othershareholders in the Fund. In addition, the Manager serves asinvestment adviser to various clients other than the Fund,some of whom may pursue strategies that are substantiallysimilar or nearly identical to investment strategies pursuedby the Fund. This “side-by-side” management may give riseto various conflicts of interest, including, for example, in

connection with the fair allocation of trades among theManager’s clients or the sharing of different, more, or moretimely information regarding investment performance,portfolio holdings, strategy developments and/or theManager’s general market outlook. Furthermore, ifinvestment personnel of the Manager hold board or otherpositions at outside companies, they could be exposed tomaterial non-public information potentially impeding ordelaying a Fund’s ability to buy or sell certain investments, orthey could otherwise be restricted in their ability toparticipate in a Fund’s investment process.

— Currency Risk – The Fund may realize a loss if it hasexposure to a non-U.S. currency, and this non-U.S. currencydeclines in value, relative to the U.S. dollar. The Fund doesnot expect to engage in currency hedging and thus expectsto be fully exposed to currency fluctuations relative to theU.S. dollar.

— Emerging Markets Risk – To the extent the Fund invests inemerging market securities, the Fund may be exposed togreater market, credit, currency, liquidity, legal, political,technical and other risks different from, or greater than, therisks of investing in developed markets.

— Equity Securities Risk – Equity securities may react morestrongly to changes in an issuer’s financial condition orprospects than other securities of the same issuer. Investingin equity securities indirectly, such as through participatorynotes or depositary receipts, may involve other risks such asthe risk that the counterparty may default or that theinvestment does not track the underlying security asexpected.

— Focused Investment Risk – Because the Fund focuses itsinvestments in a limited number of companies, its investmentstrategy could result in more risk or greater volatility inreturns than if the Fund’s investments were less focused.

— Government and Regulatory Risk – Governmental andregulatory authorities in the United States and othercountries, have taken, and may in the future take, actionsintervening in the markets in which the Fund invests and inthe economy more generally. Governmental and regulatoryauthorities may also act to increase the scope or burden ofregulations applicable to the Fund or to the companies inwhich the Fund invests. The effects of these actions on themarkets generally, and Fund’s investment program inparticular, can be uncertain and could restrict the ability ofthe Fund to fully implement its investment strategies, eithergenerally, or with respect to certain securities, industries, orcountries. By contrast, markets in some non-U.S. countrieshistorically have been subject to little regulation or oversightby governmental or regulatory authorities, which couldheighten the risk of loss due to fraud or market failures inthose countries. Governments, agencies, or other regulatorybodies in any country may adopt or change laws orregulations that could adversely affect the Fund or themarket value of an instrument held by the Fund.

— Information Technology Risk – Cyber-attacks, disruptions, orfailures that affect the Fund’s service providers, counterparties,the securities markets generally, other market participants, orissuers of securities held by the Fund may adversely affect the

Fund and its shareholders, including by causing losses for theFund or impairing Fund operations.

— IPO Risk – The Fund may purchase securities in IPOs.These securities are subject to many of the same risks ofinvesting in companies with smaller market capitalizations.Securities issued in IPOs have no trading history, andinformation about the companies may be available for verylimited periods. In addition, the prices of securities sold inIPOs may be highly volatile.

— Large-Capitalization Securities Risk – Returns oninvestments in securities of large companies could trail thereturns on investments in securities of smaller and medium-sized companies. Larger companies may be unable torespond as quickly as smaller and medium-sized companiesto competitive challenges or to changes in business, product,financial, or other market conditions. Larger companies maynot be able to achieve or maintain growth at the high ratesthat may be achieved by well-managed smaller and medium-sized companies.

— Liquidity Risk – The Fund’s investments may be subject tolow trading volume, lack of a market maker, contractual lock-in periods or regulatory restrictions, and the Fund may holdlarge positions in particular securities. As a result, it may notbe possible to sell an investment at a particular time or at anacceptable price. Liquidity risk may be magnified duringperiods of changing interest rates, significant shareholderredemptions or market turmoil. Illiquid securities may tradeat a discount from comparable, more liquid investments andmay be subject to wide fluctuations in market value. In somecases, due to unanticipated levels of illiquidity the Fund mayseek to meet its redemption obligations wholly or in part bydistributions of assets in-kind.

— Market Disruption and Geopolitical Risk – The value of theFund’s investments could be adversely affected by eventsthat disrupt securities markets and adversely affect globalmarkets such as war, terrorism, public health crises, andgeopolitical events and by changes in non-U.S. andU.S. economic and political conditions. As a result of theseevents, the Fund could lose money, experience significantredemptions, encounter operational difficulties, and sufferother negative impacts.

— Market Risk – The value of the Fund’s investments will beaffected by fluctuations in the stock markets in which theFund is invested, factors affecting a particular industry orindustries, real or perceived adverse economic conditions,changes in interest or currency rates or adverse investorsentiment generally. Declines in securities market prices mayreduce the net asset value of the Fund’s shares.

— New and Smaller-Sized Funds Risk – New funds andsmaller-sized funds will be subject to greater liquidity riskdue to their smaller asset bases and may be required to sellsecurities at disadvantageous times or prices due to a largeshareholder redemption. A fund that has been recentlyformed will have limited or no performance history forinvestors to evaluate and may not reach or maintain asufficient asset size to effectively implement its investmentstrategy.

Baillie Gifford Funds – Prospectus

— Non-U.S. Investment Risk – Non-U.S. securities are subjectto additional risks, including less liquidity, increased volatility,less transparency, withholding or other taxes, increasedvulnerability to adverse changes in local and globaleconomic conditions, less regulation, and possiblefluctuation in value due to adverse political conditions.Foreign portfolio transactions generally involve highercommission rates, transfer taxes, and custodial costs thansimilar transactions in the U.S.

— Service Provider Risk – The Fund will be affected by theManager’s investment techniques, analyses, assessmentsand employee retention. Similarly, adverse events orperformance failures at a service provider, such as humanerror, inadequate controls or insolvency, have the ability toadversely affect the Fund.

— Settlement Risk – The Fund may experience delays insettlement due to the different clearance and settlementprocedures in non-U.S. countries. Such delays may increasecredit risk to the Fund, limit the ability of the Fund to reinvestthe proceeds of a sale of securities, or prevent the Fundfrom selling securities at times and prices it considersdesirable.

— Small- and Medium-Capitalization Securities Risk – Securitiesof small- and medium-capitalization companies can be morevolatile due to various factors including more limited productlines, financial and management resources and marketdistribution channels, as well as shorter operating historiesand potentially reduced liquidity, especially during marketdeclines, than the securities of larger, more establishedcompanies.

— Underlying Funds Risk – Investments in other pooledinvestment vehicles may indirectly expose the Fund to all ofthe risks applicable to an investment in such other pool. TheFund must pay its pro rata portion of the other pooledvehicle’s fees and expenses. If such pool is an ETF or otherproduct traded on a securities exchange or otherwiseactively traded, its shares may trade at a premium ordiscount to their net asset value, an effect that might bemore pronounced in less liquid markets. Further, theManager or an affiliate may serve as investment adviser tosome pooled vehicles in which the Fund invests, leading topotential conflicts of interest.

— Valuation Risk – In certain circumstances, some of theFund’s portfolio holdings may be valued on the basis offactors other than market quotations by employing the fairvalue procedures adopted by the Board of Trustees of theTrust (the “Board”). This may occur more often in times ofmarket turmoil or reduced liquidity. Portfolio holdings that arevalued using techniques other than market quotations,including “fair valued” securities, may be subject to greaterfluctuation in their valuations from one day to the next than ifmarket quotations were used. There is no assurance that theFund could sell or close out a portfolio position for the valueestablished for it at any time, and it is possible that the Fundwould incur a loss because a portfolio position is sold orclosed out at a discount to the valuation established by theFund at that time.

PerformanceThe bar chart and table below provide some indication of therisks of investing in the Fund by showing changes in the Fund’sannual total returns from year to year and by comparing theFund’s average annual total returns with those of the Fund’sbenchmark.

Baillie Gifford China Equities Fund

Investment ObjectiveBaillie Gifford China Equities Fund seeks capital appreciation.

Fees and ExpensesThe tables below describe the fees and expenses that you maypay if you buy, hold, and sell shares of the Fund. You may payother fees, such as brokerage commissions and other fees tofinancial intermediaries, which are not reflected in the tables andexamples below.

Shareholder Fees(Fees paid directly from your investment)

Class K Institutional ClassNone None

Annual Fund Operating Expenses(Expenses that you pay each year as a percentage of the valueof your investment)

Class K Institutional ClassManagement Fees(a) 0.72% 0.72%Distribution (12b-1) Fees None NoneOther Expenses(b) 17.25% 17.40%Total Annual Fund Operating Expenses 17.97% 18.12%Fee Waiver and/or Expense Reimbursement(c) (17.10)% (17.10)%Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement(c) 0.87% 1.02%

(a) The Management Fee consists of an Advisory Fee and anAdministration and Supervisory Fee paid by the Fund to BaillieGifford Overseas Limited.

(b) Class K and Institutional Class were unfunded as of December 31,2020. Therefore, Other Expenses have been estimated for thecurrent fiscal year assuming Fund assets of $1 million.

(c) Baillie Gifford Overseas Limited has contractually agreed to waiveits fees and/or bear Other Expenses of the Fund until April 30, 2023to the extent that the Fund’s Total Annual Fund OperatingExpenses (excluding taxes, sub-accounting expenses andextraordinary expenses) exceed 0.87% for Class K and InstitutionalClass shares. This contractual agreement may only be terminatedby the Board of Trustees of the Trust. Expenses afterwaiver/reimbursement exceed 0.87% for Institutional Class due toestimated sub-accounting expenses of 0.15%.

Example of ExpensesThe example below is intended to help you compare the cost ofinvesting in the Fund with the cost of investing in other mutualfunds. It assumes that you invest $10,000 in the Fund for the timeperiods indicated, regardless of whether or not you redeem yourshares at the end of such periods. It also assumes that yourinvestment has a 5% return each year and that the Fund’soperating expenses remain the same. The example below alsoapplies any contractual expense waivers and/or expensereimbursements to the first year of each period listed in the table.

Although your actual costs may be higher or lower, based onthese assumptions, your expenses would be:

Class K Institutional Class1 Year $89 $1043 Years $3,362 $3,394

Portfolio TurnoverThe Fund pays transaction costs, such as commissions, when itbuys and sells securities (or “turns over” its portfolio). A higherportfolio turnover rate may indicate higher transaction costs andmay result in higher taxes when Fund shares are held in ataxable account. These transaction costs, which are not reflectedin “Annual Fund Operating Expenses” or in the “Example ofExpenses” above, affect the Fund’s performance. Because theFund has not commenced operations, it does not have a portfolioturnover rate.

Principal Investment StrategiesThe Fund will seek to meet its objective by investing in a portfolioof common stocks and other equity securities of companieslocated in the People’s Republic of China (“China”).

Under normal circumstances, the Fund will invest at least 80% ofits net assets (plus any borrowings for investment purposes) incommon stocks and other equity securities of companies locatedin China, regardless of where their securities are principally listedfor trading. The Fund will invest in equity securities either directlyor indirectly, such as through depositary receipts or participatorynotes and may invest in preferred stocks, convertible securitiesand warrants. The Fund may invest in any sector or industry, inissuers of any market capitalization, and may participate in initialpublic offerings (“IPOs”) and in securities offerings that are notregistered in the U.S.

The Fund’s investments can include securities of companieslisted on exchanges located in and outside of China and includeChina “A” shares (“A Shares” or “China A Shares”), which arecommon stocks and other equity securities that are listed ortraded on a Chinese stock exchange and which are quoted inrenminbi, the official currency of China. The Fund expects todirectly access China A Shares through the Shanghai-Hong KongStock Connect program and the Shenzhen-Hong Kong StockConnect program (together the “Stock Connect programs”).The Fund may in the future also directly access securities ofcompanies through the qualified foreign investor program (“QFI”formerly the Qualified Foreign Institutional Investor and RenminbiQualified Foreign Institutional Investor programs) or other meansof access which may become available in the future. In addition,the Fund may invest in equity securities indirectly, such asthrough depositary receipts or exchange traded funds (“ETFs”),especially during extended closures of the Chinese markets.

The portfolio managers employ a bottom-up approach to stockselection and will principally select companies without beingconstrained by the Fund’s benchmark, the MSCI China AllShares Index. The portfolio managers focus on companyresearch and the long-term outlook of companies and industries.Ideas can come from a wide variety of sources, including, but notlimited to, research trips, company meetings, and relationshipswith industry thought leaders and academic institutions. Stockideas normally will be researched to assess a range of factors,

including: long-term growth potential, geographic and industrypositioning, competitive advantage, management, financialstrength, and valuation. The portfolio managers employ anadditional due diligence process for Chinese companies in lightof the comparative immaturity of the Chinese capital markets andthe status of China as an emerging market economy.

The portfolio managers seek to identify exciting growthcompanies in China across a broad range of sectors with thepotential to achieve the Fund’s investment objective. Theintended outcome is a non-diversified portfolio of between 40 and80 growth companies with the potential to outperform thebenchmark over the long term. The Fund intends to operate as anon-diversified fund, which means that it may invest a relativelylarge percentage of its assets in a small number of issuers,industries, or sectors. The Fund aims to hold securities for longperiods (typically 5+ years), which is expected to result in arelatively low portfolio turnover and be in line with the Fund’slong-term investment outlook. It is expected that the Fund willhold large positions, over 5%, in a small number of companiesconsistent with the Fund operating as a non-diversified fund.

The Fund may invest without limitation in securities quoted ordenominated in currencies other than the U.S. dollar and mayhold such currencies. The Fund does not expect to engage incurrency hedging and thus expects to be fully exposed tocurrency fluctuations relative to the U.S. dollar.

Principal RisksThe Fund’s net asset value and returns will be impacted by theperformance of the underlying investments of the Fund. Aninvestment in the Fund is not a deposit in a bank and is notinsured or guaranteed by the Federal Deposit InsuranceCorporation or any other government agency. You could losemoney by investing in the Fund.

The principal risks of investing in the Fund (in alphabetical orderafter the first six risks) are:

— China Risk – Investing in securities of Chinese issuersinvolves certain risks and considerations not typicallyassociated with investing in securities of U.S. issuers,including, among others, more frequent trading suspensionsand government interventions (including by nationalization ofassets), currency exchange rate fluctuations or blockages,limits on the use of brokers and on foreign ownership,different financial reporting standards, higher dependence onexports and international trade, potential for increased tradetariffs, sanctions, embargoes and other trade limitations,custody risks, and potential adverse tax consequences. U.S.sanctions or other investment restrictions could preclude theFund from investing in certain Chinese issuers or cause theFund to sell investments at a disadvantageous time.Significant portions of the Chinese securities markets maybecome rapidly illiquid, as Chinese issuers have the ability tosuspend the trading of their equity securities, and haveshown a willingness to exercise that option in response tomarket volatility and other events.

— Investment Style Risk – Baillie Gifford Overseas Limited(the “Manager”) actively makes investment decisions for theFund through bottom-up stock selection. Accordingly, theFund will have risk characteristics that differ from its

benchmark index. The Manager’s judgments about theattractiveness, relative value, or potential appreciation of aparticular stock may prove to be incorrect and cause theFund to lose money or underperform compared to itsbenchmark index. There can be no assurance that theManager’s investment decisions will produce the desiredresults.

— Growth Stock Risk – The prices of growth stocks may bebased largely on expectations of future earnings, and theirprices can decline rapidly and significantly in reaction tonegative news. Growth stocks may underperform stocks inother broad style categories (and the stock market as awhole) over any period of time and may shift in and out offavor with investors generally, sometimes rapidly, dependingon changes in market, economic, and other factors.

— Long-Term Investment Strategy Risk – The Fund pursues along-term investment approach, typically seeking returnsover a period of several years. This investment style maycause the Fund to lose money or underperform compared toits benchmark index or other mutual funds over extendedperiods of time, and the Fund may not perform as expectedin the long term. An investment in the Fund may be moresuitable for long-term investors who can bear the risk ofshort- or medium-term fluctuations in the value of the Fund’sportfolio.

— Non-Diversification Risk – The Fund is classified as a “non-diversified” fund. A non-diversified fund may hold a smallernumber of portfolio securities, with larger positions in eachsecurity it holds, than many other mutual funds. To the extentthe Fund invests in a relatively small number of issuers, adecline in the market value of a particular security held bythe Fund may affect its value more than if it invested in alarger number of issuers. The value of the Fund’s sharesmay be more volatile than the values of shares of morediversified funds. See also “Focused Investment Risk.”

— Geographic Focus Risk – The Fund expects to focus itsinvestments in a limited number of countries or geographicregions, and as a result may not offer the same level ofdiversification of risks as a more broadly global fundbecause the Fund will be exposed to a smaller geographicarea. The performance of a fund that is less diversifiedacross countries or geographic regions will be closely tied tomarket, currency, economic, political, environmental, orregulatory conditions and developments in the countries orregions in which the fund invests, and may be more volatilethan the performance of a more geographically-diversifiedportfolio.

— Conflicts of Interest Risk – The Manager’s relationships withthe Fund’s institutional investor base may give rise to variousconflicts of interest, since the Manager will sometimes havean incentive to favor those shareholders over othershareholders in the Fund. In addition, the Manager serves asinvestment adviser to various clients other than the Fund,some of whom may pursue strategies that are substantiallysimilar or nearly identical to investment strategies pursuedby the Fund. This “side-by-side” management may give riseto various conflicts of interest, including, for example, inconnection with the fair allocation of trades among the

Furthermore, ifinvestment personnel of the Manager hold board or otherpositions at outside companies, they could be exposed tomaterial non-public information potentially impeding ordelaying the Fund’s ability to buy or sell certain investments,or they could otherwise be restricted in their ability toparticipate in the Fund’s investment process.

— Currency Risk – The Fund may realize a loss if it hasexposure to a non-U.S. currency, and this non-U.S. currencydeclines in value, relative to the U.S. dollar. The Fund doesnot expect to engage in currency hedging and thus expectsto be fully exposed to currency fluctuations relative to theU.S. dollar.

— Emerging Markets Risk – To the extent the Fund invests inemerging market securities, the Fund may be exposed togreater market, credit, currency, liquidity, legal, political,technical and other risks different from, or greater than, therisks of investing in developed markets.

— Equity Securities Risk – Equity securities may react morestrongly to changes in an issuer’s financial condition orprospects than other securities of the same issuer. Investingin equity securities indirectly, such as through participatorynotes or depositary receipts, may involve other risks such asthe risk that the counterparty may default or that theinvestment does not track the underlying security asexpected.

— Focused Investment Risk – Because the Fund focuses itsinvestments in a limited number of companies, its investmentstrategy could result in more risk or greater volatility inreturns than if the Fund’s investments were less focused.

— Government and Regulatory Risk – Governmental andregulatory authorities in the United States and othercountries, have taken, and may in the future take, actionsintervening in the markets in which the Fund invests and inthe economy more generally. Governmental and regulatoryauthorities may also act to increase the scope or burden ofregulations applicable to the Fund or to the companies inwhich the Fund invests. The effects of these actions on themarkets generally, and Fund’s investment program inparticular, can be uncertain and could restrict the ability ofthe Fund to fully implement its investment strategies, eithergenerally, or with respect to certain securities, industries, orcountries. By contrast, markets in some non-U.S. countrieshistorically have been subject to little regulation or oversightby governmental or regulatory authorities, which couldheighten the risk of loss due to fraud or market failures inthose countries. Governments, agencies, or other regulatorybodies in any country may adopt or change laws orregulations that could adversely affect the Fund or themarket value of an instrument held by the Fund.

— Information Technology Risk – Cyber-attacks, disruptions, orfailures that affect the Fund’s service providers, counterparties,the securities markets generally, other market participants, orissuers of securities held by the Fund may adversely affect the

Fund and its shareholders, including by causing losses for theFund or impairing Fund operations.

— IPO Risk – The Fund may purchase securities in IPOs.These securities are subject to many of the same risks ofinvesting in companies with smaller market capitalizations.Securities issued in IPOs have no trading history, andinformation about the companies may be available for verylimited periods. In addition, the prices of securities sold inIPOs may be highly volatile.

— Large-Capitalization Securities Risk – Returns oninvestments in securities of large companies could trail thereturns on investments in securities of smaller and medium-sized companies. Larger companies may be unable torespond as quickly as smaller and medium-sized companiesto competitive challenges or to changes in business, product,financial, or other market conditions. Larger companies maynot be able to achieve or maintain growth at the high ratesthat may be achieved by well-managed smaller and medium-sized companies.

— Liquidity Risk – The Fund’s investments may be subject tolow trading volume, lack of a market maker, contractual lock-in periods or regulatory restrictions, and the Fund may holdlarge positions in particular securities. As a result, it may notbe possible to sell an investment at a particular time or at anacceptable price. Liquidity risk may be magnified duringperiods of changing interest rates, significant shareholderredemptions or market turmoil. Illiquid securities may tradeat a discount from comparable, more liquid investments andmay be subject to wide fluctuations in market value. In somecases, due to unanticipated levels of illiquidity the Fund mayseek to meet its redemption obligations wholly or in part bydistributions of assets in-kind.

— Market Disruption and Geopolitical Risk – The value of theFund’s investments could be adversely affected by eventsthat disrupt securities markets and adversely affect globalmarkets such as war, terrorism, public health crises, andgeopolitical events and by changes in non-U.S. andU.S. economic and political conditions. As a result of theseevents, the Fund could lose money, experience significantredemptions, encounter operational difficulties, and sufferother negative impacts.

— Market Risk – The value of the Fund’s investments will beaffected by fluctuations in the stock markets in which theFund is invested, factors affecting a particular industry orindustries, real or perceived adverse economic conditions,changes in interest or currency rates or adverse investorsentiment generally. Declines in securities market prices mayreduce the net asset value of the Fund’s shares.

— New and Smaller-Sized Funds Risk – New funds andsmaller-sized funds will be subject to greater liquidity riskdue to their smaller asset bases and may be required to sellsecurities at disadvantageous times or prices due to a largeshareholder redemption. A fund that has been recentlyformed will have limited or no performance history forinvestors to evaluate and may not reach or maintain asufficient asset size to effectively implement its investmentstrategy.

— Non-U.S. Investment Risk – Non-U.S. securities are subjectto additional risks, including less liquidity, increased volatility,less transparency, withholding or other taxes, increasedvulnerability to adverse changes in local and globaleconomic conditions, less regulation, and possiblefluctuation in value due to adverse political conditions.Foreign portfolio transactions generally involve highercommission rates, transfer taxes, and custodial costs thansimilar transactions in the U.S.

— Service Provider Risk – The Fund will be affected by theManager’s investment techniques, analyses, assessmentsand employee retention. Similarly, adverse events orperformance failures at a service provider, such as humanerror, inadequate controls or insolvency, have the ability toadversely affect the Fund.

— Settlement Risk – The Fund may experience delays insettlement due to the different clearance and settlementprocedures in non-U.S. countries. Such delays may increasecredit risk to the Fund, limit the ability of the Fund to reinvestthe proceeds of a sale of securities, or prevent the Fundfrom selling securities at times and prices it considersdesirable.

— Small- and Medium-Capitalization Securities Risk – Securitiesof small- and medium-capitalization companies can be morevolatile due to various factors including more limited productlines, financial and management resources and marketdistribution channels, as well as shorter operating historiesand potentially reduced liquidity, especially during marketdeclines, than the securities of larger, more establishedcompanies.

— Underlying Funds Risk – Investments in other pooledinvestment vehicles may indirectly expose the Fund to all ofthe risks applicable to an investment in such other pool. Afund must pay its pro rata portion of the other pooledvehicle’s fees and expenses. If such pool is an ETF or otherproduct traded on a securities exchange or otherwiseactively traded, its shares may trade at a premium ordiscount to their net asset value, an effect that might bemore pronounced in less liquid markets. Further, theManager or an affiliate may serve as investment adviser tosome pooled vehicles in which the Fund invests, leading topotential conflicts of interest.

— Valuation Risk – In certain circumstances, some of theFund’s portfolio holdings may be valued on the basis offactors other than market quotations by employing the fairvalue procedures adopted by the Board of Trustees of theTrust (the “Board”). This may occur more often in times ofmarket turmoil or reduced liquidity. Portfolio holdings that arevalued using techniques other than market quotations,including “fair valued” securities, may be subject to greaterfluctuation in their valuations from one day to the next than ifmarket quotations were used. There is no assurance that theFund could sell or close out a portfolio position for the valueestablished for it at any time, and it is possible that the Fundwould incur a loss because a portfolio position is sold orclosed out at a discount to the valuation established by theFund at that time.

Baillie Gifford Developed EAFE All Cap Fund

Investment ObjectiveBaillie Gifford Developed EAFE All Cap Fund seeks capitalappreciation.

Fees and ExpensesThe tables below describe the fees and expenses that you maypay if you buy, hold, and sell shares of the Fund. You may payother fees, such as brokerage commissions and other fees tofinancial intermediaries, which are not reflected in the tables andexamples below.

Shareholder Fees(Fees paid directly from your investment)

Class K Institutional ClassNone None

Annual Fund Operating Expenses(Expenses that you pay each year as a percentage of the valueof your investment)

Class K Institutional ClassManagement Fees(a) 0.52% 0.52%Distribution (12b-1) Fees None NoneOther Expenses(b) 0.12% 0.24%Total Annual Fund Operating Expenses 0.64% 0.76%

(a) The Management Fee consists of an Advisory Fee and anAdministration and Supervisory Fee paid by the Fund to BaillieGifford Overseas Limited.

(b) Other Expenses differ due to sub-accounting expenses.

Example of ExpensesThe example below is intended to help you compare the cost ofinvesting in the Fund with the cost of investing in other mutualfunds. It assumes that you invest $10,000 in the Fund for the timeperiods indicated, regardless of whether or not you redeem yourshares at the end of such periods. It also assumes that yourinvestment has a 5% return each year and that the Fund’soperating expenses remain the same.

Although your actual costs may be higher or lower, based onthese assumptions, your expenses would be:

Class K Institutional Class1 Year $65 $783 Years $205 $2435 Years $357 $42210 Years $798 $942

Portfolio TurnoverThe Fund pays transaction costs, such as commissions, when itbuys and sells securities (or “turns over” its portfolio). A higherportfolio turnover rate may indicate higher transaction costs andmay result in higher taxes when Fund shares are held in ataxable account. These transaction costs, which are not reflectedin “Annual Fund Operating Expenses” or in the “Example ofExpenses” above, affect the Fund’s performance. During theFund’s most recent fiscal year, the Fund’s portfolio turnover ratewas 12% of the average value of its portfolio.

Principal Investment StrategiesThe Fund seeks to meet its objective by investing in a portfolio ofcommon stocks and other equity securities of issuers located innon-U.S. countries with developed markets.

Under normal circumstances, the Fund invests at least 80% of itsnet assets (plus any borrowings for investment purposes) incommon stocks and other equity securities of companies whoseprincipal activities are in developed markets in Europe,Australasia and/or the Far East. The Fund invests in equitysecurities either directly or indirectly, such as through depositaryreceipts, and may invest in preferred stocks, convertiblesecurities and warrants. The Fund is not constrained with respectto market capitalization and may participate in initial publicofferings (“IPOs”) and in securities offerings that are notregistered in the U.S. In selecting companies for investment, theportfolio managers focus on issuers in developed markets, but insome circumstances may gain exposure to emerging markets.

The portfolio managers employ a bottom-up approach to stockselection and retain flexibility to invest without being constrainedby the MSCI EAFE benchmark. The portfolio managers focus oncompany research and the long-term outlook of companies andindustries. Ideas can come from a wide variety of sources,including, but not limited to, research trips, company meetings,and relationships with industry thought leaders and academicinstitutions. Stock ideas are normally researched to assess arange of factors that may include: long-term growth potential,geographic and industry positioning, competitive advantage,management, financial strength and valuation. The intendedoutcome is a diversified portfolio of between 50 and 90 growthcompanies with the potential to outperform the benchmark overthe long term. The process can result in significant exposure to asingle country or a small number of countries, which in recentperiods has included Japan. The Fund aims to hold securities forlong periods (typically 5+ years), which results in relatively lowportfolio turnover and is in line with the Fund’s long-terminvestment outlook. The Fund may invest without limitation insecurities quoted or denominated in currencies other than theU.S. dollar and may hold such currencies. The Fund does notexpect to engage in currency hedging and thus expects to befully exposed to currency fluctuations relative to the U.S. dollar.

Principal RisksThe Fund’s net asset value and returns will be impacted by theperformance of the underlying investments of the Fund. Aninvestment in the Fund is not a deposit in a bank and is notinsured or guaranteed by the Federal Deposit InsuranceCorporation or any other government agency. You could losemoney by investing in the Fund.

The principal risks of investing in the Fund (in alphabetical orderafter the first five risks) are:

— Investment Style Risk – Baillie Gifford Overseas Limited(the “Manager”) actively makes investment decisions for theFund through bottom-up stock selection. Accordingly, theFund will have risk characteristics that differ from itsbenchmark index. The Manager’s judgments about theattractiveness, relative value, or potential appreciation of aparticular stock may prove to be incorrect and cause theFund to lose money or underperform compared to itsbenchmark index. There can be no assurance that the

Manager’s investment decisions will produce the desiredresults.

— Growth Stock Risk – The prices of growth stocks may bebased largely on expectations of future earnings, and theirprices can decline rapidly and significantly in reaction tonegative news. Growth stocks may underperform stocks inother broad style categories (and the stock market as awhole) over any period of time and may shift in and out offavor with investors generally, sometimes rapidly, dependingon changes in market, economic, and other factors.

— Long-Term Investment Strategy Risk – The Fund pursues along-term investment approach, typically seeking returnsover a period of several years. This investment style maycause the Fund to lose money or underperform compared toits benchmark index or other mutual funds over extendedperiods of time, and the Fund may not perform as expectedin the long term. An investment in the Fund may be moresuitable for long-term investors who can bear the risk ofshort- or medium-term fluctuations in the value of the Fund’sportfolio.

— Non-U.S. Investment Risk – Non-U.S. securities are subjectto additional risks, including less liquidity, increased volatility,less transparency, withholding or other taxes, increasedvulnerability to adverse changes in local and globaleconomic conditions, less regulation, and possiblefluctuation in value due to adverse political conditions.Foreign portfolio transactions generally involve highercommission rates, transfer taxes, and custodial costs thansimilar transactions in the U.S.

— Asia Risk – Investing in securities of companies located in orwith exposure to Asian countries involves certain risks andconsiderations not typically associated with investing insecurities of U.S. issuers, including different financialreporting standards, currency exchange rate fluctuations,and highly regulated markets with the potential forgovernment interference. The economies of many Asiancountries are heavily dependent on international trade andon only a few industries or commodities and, as a result, canbe adversely affected by trade barriers, exchange controlsand other measures imposed or negotiated by the countrieswith which they trade. Some Asian securities may be lessliquid than U.S. or other foreign securities. See “China Risk”and “Japan Risk” for additional details regarding the risks ofinvesting in those countries.

— China Risk – Investing in securities of Chinese issuersinvolves certain risks and considerations not typicallyassociated with investing in securities of U.S. issuers,including, among others, more frequent trading suspensionsand government interventions (including by nationalization ofassets), currency exchange rate fluctuations or blockages,limits on the use of brokers and on foreign ownership,different financial reporting standards, higher dependence onexports and international trade, potential for increased tradetariffs, sanctions, embargoes and other trade limitations,custody risks, and potential adverse tax consequences.U.S. sanctions or other investment restrictions could precludethe Fund from investing in certain Chinese issuers or cause

the Fund to sell investments at a disadvantageous time.Significant portions of the Chinese securities markets maybecome rapidly illiquid, as Chinese issuers have the ability tosuspend the trading of their equity securities, and haveshown a willingness to exercise that option in response tomarket volatility and other events.

— Conflicts of Interest Risk – The Manager’s relationships withthe Fund’s institutional investor base may give rise to variousconflicts of interest, since the Manager will sometimes havean incentive to favor those shareholders over othershareholders in the Fund. In addition, the Manager serves asinvestment adviser to various clients other than the Fund,some of whom may pursue strategies that are substantiallysimilar or nearly identical to investment strategies pursuedby the Fund. This “side-by-side” management may give riseto various conflicts of interest, including, for example, inconnection with the fair allocation of trades among theManager’s clients or the sharing of different, more, or moretimely information regarding investment performance,portfolio holdings, strategy developments and/or theManager’s general market outlook. Furthermore, ifinvestment personnel of the Manager hold board or otherpositions at outside companies, they could be exposed tomaterial non-public information potentially impeding ordelaying a Fund’s ability to buy or sell certain investments, orthey could otherwise be restricted in their ability toparticipate in a Fund’s investment process.

— Currency Risk – The Fund may realize a loss if it hasexposure to a non-U.S. currency, and this non-U.S. currencydeclines in value, relative to the U.S. dollar. The Fund doesnot expect to engage in currency hedging and thus expectsto be fully exposed to currency fluctuations relative to theU.S. dollar.

— Equity Securities Risk – Equity securities may react morestrongly to changes in an issuer’s financial condition orprospects than other securities of the same issuer. Investingin equity securities indirectly, such as through participatorynotes or depositary receipts, may involve other risks such asthe risk that the counterparty may default or that theinvestment does not track the underlying security asexpected.

— Focused Investment Risk – Should the Fund focus itsinvestments in related, or a limited number of, countries,regions, sectors, or companies, this would create more riskand greater volatility than if the Fund’s investments wereless focused.

— Geographic Focus Risk – The Fund expects to focus itsinvestments in a limited number of countries or geographicregions, and as a result may not offer the same level ofdiversification of risks as a more broadly global fundbecause the Fund will be exposed to a smaller geographicarea. The performance of a fund that is less diversifiedacross countries or geographic regions will be closely tied tomarket, currency, economic, political, environmental, orregulatory conditions and developments in the countries orregions in which the fund invests, and may be more volatile

— Government and Regulatory Risk – Governmental andregulatory authorities in the United States and othercountries, have taken, and may in the future take, actionsintervening in the markets in which the Fund invests and inthe economy more generally. Governmental and regulatoryauthorities may also act to increase the scope or burden ofregulations applicable to the Fund or to the companies inwhich the Fund invests. The effects of these actions on themarkets generally, and Fund’s investment program inparticular, can be uncertain and could restrict the ability ofthe Fund to fully implement its investment strategies, eithergenerally, or with respect to certain securities, industries, orcountries. By contrast, markets in some non-U.S. countrieshistorically have been subject to little regulation or oversightby governmental or regulatory authorities, which couldheighten the risk of loss due to fraud or market failures inthose countries. Governments, agencies, or other regulatorybodies in any country may adopt or change laws orregulations that could adversely affect the Fund or themarket value of an instrument held by the Fund.

— Information Technology Risk – Cyber-attacks, disruptions, orfailures that affect the Fund’s service providers, counterparties,the securities markets generally, other market participants, orissuers of securities held by the Fund may adversely affect theFund and its shareholders, including by causing losses for theFund or impairing Fund operations.

— IPO Risk – The Fund may purchase securities in IPOs.These securities are subject to many of the same risks ofinvesting in companies with smaller market capitalizations.Securities issued in IPOs have no trading history, andinformation about the companies may be available for verylimited periods. In addition, the prices of securities sold inIPOs may be highly volatile.

— Japan Risk – The Japanese economy has only recentlyemerged from a prolonged economic downturn. Since theyear 2000, Japan’s economic growth rate has remainedrelatively low, and it may remain low in the future. Japan’seconomy is characterized by an aging demographic,declining population, large government debt, and a highlyregulated labor market. In the longer term, Japan will have toaddress the effects of an aging population, including theimpact of a shrinking work force and higher welfare costs.Japan’s economic recovery has been affected by economicdistress resulting from a number of natural disasters,including disasters that caused damage to nuclear powerplants in the region. Such environmental catastrophes havecaused Japan’s financial markets to fluctuate dramatically.Japan continues to be subject to the risk of natural disasters,such as earthquakes, volcanic eruptions, typhoons andtsunamis, which could negatively affect the Japaneseeconomy.

— Large-Capitalization Securities Risk – Returns oninvestments in securities of large companies could trail thereturns on investments in securities of smaller and medium-sized companies. Larger companies may be unable to

respond as quickly as smaller and medium-sized companiesto competitive challenges or to changes in business, product,financial, or other market conditions. Larger companies maynot be able to achieve or maintain growth at the high ratesthat may be achieved by well-managed smaller and medium-sized companies.

As a result of theseevents, the Fund could lose money, experience significantredemptions, encounter operational difficulties, and sufferother negative impacts.

— Market Risk – The value of the Fund’s investments will beaffected by fluctuations in the stock markets in which theFund is invested, factors affecting a particular industry orindustries, real or perceived adverse economic conditions,changes in interest or currency rates or adverse investorsentiment generally. Declines in securities market prices mayreduce the net asset value of the Fund’s shares.

Baillie Gifford EAFE Plus All Cap Fund

Investment ObjectiveBaillie Gifford EAFE Plus All Cap Fund seeks capitalappreciation.

Fees and ExpensesThe tables below describe the fees and expenses that you maypay if you buy, hold, and sell shares of the Fund. You may payother fees, such as brokerage commissions and other fees tofinancial intermediaries, which are not reflected in the tables andexamples below.

Shareholder Fees(Fees paid directly from your investment)

Class K Institutional ClassNone None

Annual Fund Operating Expenses(Expenses that you pay each year as a percentage of the valueof your investment)

Class K Institutional ClassManagement Fees(a) 0.52% 0.52%Distribution (12b-1) Fees None NoneOther Expenses(b) 0.10% 0.20%Total Annual Fund Operating Expenses 0.62% 0.72%

(a) The Management Fee consists of an Advisory Fee and anAdministration and Supervisory Fee paid by the Fund to BaillieGifford Overseas Limited.

(b) Other Expenses differ due to sub-accounting expenses.

Example of ExpensesThe example below is intended to help you compare the cost ofinvesting in the Fund with the cost of investing in other mutualfunds. It assumes that you invest $10,000 in the Fund for the timeperiods indicated, regardless of whether or not you redeem yourshares at the end of such periods. It also assumes that yourinvestment has a 5% return each year and that the Fund’soperating expenses remain the same.

Although your actual costs may be higher or lower, based onthese assumptions, your expenses would be:

Class K Institutional Class1 Year $63 $743 Years $199 $2305 Years $346 $40110 Years $774 $894

Portfolio TurnoverThe Fund pays transaction costs, such as commissions, when itbuys and sells securities (or “turns over” its portfolio). A higherportfolio turnover rate may indicate higher transaction costs andmay result in higher taxes when Fund shares are held in ataxable account. These transaction costs, which are not reflectedin “Annual Fund Operating Expenses” or in the “Example ofExpenses” above, affect the Fund’s performance. During theFund’s most recent fiscal year, the Fund’s portfolio turnover ratewas 20% of the average value of its portfolio.

Principal Investment StrategiesThe Fund seeks to meet its objective by investing in a portfolio ofcommon stocks and other equity securities of issuers located innon-U.S. countries with developed and emerging markets.

Under normal circumstances, the Fund invests at least 85% of itsnet assets (plus any borrowings for investment purposes) incommon stocks and other equity securities of companies whoseprincipal activities are in Europe, Australasia and/or the Far East.The Fund invests in equity securities either directly or indirectly,such as through depositary receipts, and may invest in preferredstocks, convertible securities and warrants. The Fund is notconstrained with respect to market capitalization and mayparticipate in initial public offerings (“IPOs”) and in securitiesofferings that are not registered in the U.S. In selectingcompanies for investment, the portfolio managers focus onissuers in both developed and emerging markets.

The portfolio managers employ a bottom-up approach to stockselection and retain flexibility to invest without being constrainedby the MSCI EAFE benchmark. The portfolio managers focus oncompany research and the long-term outlook of companies andindustries. Ideas can come from a wide variety of sources,including, but not limited to, research trips, company meetings,and relationships with industry thought leaders and academicinstitutions. Stock ideas are normally researched to assess arange of factors that may include: long-term growth potential,geographic and industry positioning, competitive advantage,management, financial strength and valuation. The intendedoutcome is a diversified portfolio of between 60 and 90 growthcompanies with the potential to outperform the benchmark overthe long term. The process can result in significant exposure to asingle country or a small number of countries, which in recentperiods has included Japan. The Fund aims to hold securities forlong periods (typically 5+ years), which results in relatively lowportfolio turnover and is in line with the Fund’s long-terminvestment outlook.

The Fund may invest without limitation in securities quoted ordenominated in currencies other than the U.S. dollar and mayhold such currencies. The Fund does not expect to engage incurrency hedging and thus expects to be fully exposed tocurrency fluctuations relative to the U.S. dollar.

Principal RisksThe Fund’s net asset value and returns will be impacted by theperformance of the underlying investments of the Fund. Aninvestment in the Fund is not a deposit in a bank and is notinsured or guaranteed by the Federal Deposit InsuranceCorporation or any other government agency. You could losemoney by investing in the Fund.

The principal risks of investing in the Fund (in alphabetical orderafter the first six risks) are:

— Investment Style Risk – Baillie Gifford Overseas Limited (the“Manager”) actively makes investment decisions for the Fundthrough bottom-up stock selection. Accordingly, the Fund willhave risk characteristics that differ from its benchmark index.The Manager’s judgments about the attractiveness, relativevalue, or potential appreciation of a particular stock mayprove to be incorrect and cause the Fund to lose money orunderperform compared to its benchmark index. There can

Baillie Gifford Funds – Prospectus

be no assurance that the Manager’s investment decisions willproduce the desired results.

— Growth Stock Risk – The prices of growth stocks may bebased largely on expectations of future earnings, and theirprices can decline rapidly and significantly in reaction tonegative news. Growth stocks may underperform stocks inother broad style categories (and the stock market as awhole) over any period of time and may shift in and out offavor with investors generally, sometimes rapidly, dependingon changes in market, economic, and other factors.

— Long-Term Investment Strategy Risk – The Fund pursues along-term investment approach, typically seeking returnsover a period of several years. This investment style maycause the Fund to lose money or underperform compared toits benchmark index or other mutual funds over extendedperiods of time, and the Fund may not perform as expectedin the long term. An investment in the Fund may be moresuitable for long-term investors who can bear the risk ofshort- or medium-term fluctuations in the value of the Fund’sportfolio.

— Non-U.S. Investment Risk – Non-U.S. securities are subjectto additional risks, including less liquidity, increased volatility,less transparency, withholding or other taxes, increasedvulnerability to adverse changes in local and globaleconomic conditions, less regulation, and possiblefluctuation in value due to adverse political conditions.Foreign portfolio transactions generally involve highercommission rates, transfer taxes, and custodial costs thansimilar transactions in the U.S.

— Emerging Markets Risk – To the extent the Fund invests inemerging market securities, the Fund may be exposed togreater market, credit, currency, liquidity, legal, political,technical and other risks different from, or greater than, therisks of investing in developed markets.

— Asia Risk – Investing in securities of companies located in orwith exposure to Asian countries involves certain risks andconsiderations not typically associated with investing insecurities of U.S. issuers, including different financialreporting standards, currency exchange rate fluctuations,and highly regulated markets with the potential forgovernment interference. The economies of many Asiancountries are heavily dependent on international trade andon only a few industries or commodities and, as a result, canbe adversely affected by trade barriers, exchange controlsand other measures imposed or negotiated by the countrieswith which they trade. Some Asian securities may be lessliquid than U.S. or other foreign securities. See “China Risk”and “Japan Risk” for additional details regarding the risks ofinvesting in those countries.

Additionally, many of the economies of countries in Asia areconsidered emerging market or frontier market economies.These Asian economies are often characterized by highinflation, undeveloped financial service sectors, frequentcurrency fluctuations, devaluations, or restrictions, politicaland social instability, and less efficient markets. See“Emerging Markets Risk” for additional details regarding therisks of investing in such countries.

— China Risk – Investing in securities of Chinese issuersinvolves certain risks and considerations not typicallyassociated with investing in securities of U.S. issuers,including, among others, more frequent trading suspensionsand government interventions (including by nationalization ofassets), currency exchange rate fluctuations or blockages,limits on the use of brokers and on foreign ownership,different financial reporting standards, higher dependence onexports and international trade, potential for increased tradetariffs, sanctions, embargoes and other trade limitations, andcustody risks. U.S. sanctions or other investment restrictionscould preclude the Fund from investing in certain Chineseissuers or cause the Fund to sell investments at adisadvantageous time. Significant portions of the Chinesesecurities markets may become rapidly illiquid, as Chineseissuers have the ability to suspend the trading of their equitysecurities, and have shown a willingness to exercise thatoption in response to market volatility and other events.

— Conflicts of Interest Risk – The Manager’s relationships withthe Fund’s institutional investor base may give rise to variousconflicts of interest, since the Manager will sometimes havean incentive to favor those shareholders over othershareholders in the Fund. In addition, the Manager serves asinvestment adviser to various clients other than the Fund,some of whom may pursue strategies that are substantiallysimilar or nearly identical to investment strategies pursuedby the Fund. This “side-by-side” management may give riseto various conflicts of interest, including, for example, inconnection with the fair allocation of trades among theManager’s clients or the sharing of different, more, or moretimely information regarding investment performance,portfolio holdings, strategy developments and/or theManager’s general market outlook. Furthermore, ifinvestment personnel of the Manager hold board or otherpositions at outside companies, they could be exposed tomaterial non-public information potentially impeding ordelaying a Fund’s ability to buy or sell certain investments, orthey could otherwise be restricted in their ability toparticipate in a Fund’s investment process.

— Currency Risk – The Fund may realize a loss if it hasexposure to a non-U.S. currency, and this non-U.S. currencydeclines in value, relative to the U.S. dollar. The Fund doesnot expect to engage in currency hedging and thus expectsto be fully exposed to currency fluctuations relative to theU.S. dollar.

— Equity Securities Risk – Equity securities may react morestrongly to changes in an issuer’s financial condition orprospects than other securities of the same issuer. Investingin equity securities indirectly, such as through participatorynotes or depositary receipts, may involve other risks such asthe risk that the counterparty may default or that theinvestment does not track the underlying security asexpected.

— Focused Investment Risk – Should the Fund focus itsinvestments in related, or a limited number of, countries,regions, sectors, or companies, this would create more riskand greater volatility than if the Fund’s investments wereless focused.

Baillie Gifford Funds – Prospectus

— Geographic Focus Risk – The Fund expects to focus itsinvestments in a limited number of countries or geographicregions, and as a result may not offer the same level ofdiversification of risks as a more broadly global fundbecause the Fund will be exposed to a smaller geographicarea. The performance of a fund that is less diversifiedacross countries or geographic regions will be closely tied tomarket, currency, economic, political, environmental, orregulatory conditions and developments in the countries orregions in which the fund invests, and may be more volatilethan the performance of a more geographically-diversifiedportfolio.

— Government and Regulatory Risk – Governmental andregulatory authorities in the United States and othercountries, have taken, and may in the future take, actionsintervening in the markets in which the Fund invests and inthe economy more generally. Governmental and regulatoryauthorities may also act to increase the scope or burden ofregulations applicable to the Fund or to the companies inwhich the Fund invests. The effects of these actions on themarkets generally, and Fund’s investment program inparticular, can be uncertain and could restrict the ability ofthe Fund to fully implement its investment strategies, eithergenerally, or with respect to certain securities, industries, orcountries. By contrast, markets in some non-U.S. countrieshistorically have been subject to little regulation or oversightby governmental or regulatory authorities, which couldheighten the risk of loss due to fraud or market failures inthose countries. Governments, agencies, or other regulatorybodies in any country may adopt or change laws orregulations that could adversely affect the Fund or themarket value of an instrument held by the Fund.

— Information Technology Risk – Cyber-attacks, disruptions, orfailures that affect the Fund’s service providers, counterparties,the securities markets generally, other market participants, orissuers of securities held by the Fund may adversely affect theFund and its shareholders, including by causing losses for theFund or impairing Fund operations.

— IPO Risk – The Fund may purchase securities in IPOs.These securities are subject to many of the same risks ofinvesting in companies with smaller market capitalizations.Securities issued in IPOs have no trading history, andinformation about the companies may be available for verylimited periods. In addition, the prices of securities sold inIPOs may be highly volatile.

— Japan Risk – The Japanese economy has only recentlyemerged from a prolonged economic downturn. Since theyear 2000, Japan’s economic growth rate has remainedrelatively low, and it may remain low in the future. Japan’seconomy is characterized by an aging demographic,declining population, large government debt, and a highlyregulated labor market. In the longer term, Japan will have toaddress the effects of an aging population, including theimpact of a shrinking work force and higher welfare costs.Japan’s economic recovery has been affected by economicdistress resulting from a number of natural disasters,including disasters that caused damage to nuclear powerplants in the region. Such environmental catastrophes havecaused Japan’s financial markets to fluctuate dramatically.

Japan continues to be subject to the risk of natural disasters,such as earthquakes, volcanic eruptions, typhoons andtsunamis, which could negatively affect the Japaneseeconomy.

— Large-Capitalization Securities Risk – Returns oninvestments in securities of large companies could trail thereturns on investments in securities of smaller and medium-sized companies. Larger companies may be unable torespond as quickly as smaller and medium-sized companiesto competitive challenges or to changes in business, product,financial, or other market conditions. Larger companies maynot be able to achieve or maintain growth at the high ratesthat may be achieved by well-managed smaller and medium-sized companies.

— Liquidity Risk – The Fund’s investments may be subject tolow trading volume, lack of a market maker, contractual lock-in periods or regulatory restrictions, and the Fund may holdlarge positions in particular securities. As a result, it may notbe possible to sell an investment at a particular time or at anacceptable price. Liquidity risk may be magnified duringperiods of changing interest rates, significant shareholderredemptions or market turmoil. Illiquid securities may tradeat a discount from comparable, more liquid investments andmay be subject to wide fluctuations in market value. In somecases, due to unanticipated levels of illiquidity the Fund mayseek to meet its redemption obligations wholly or in part bydistributions of assets in-kind.

— Market Disruption and Geopolitical Risk – The value of theFund’s investments could be adversely affected by eventsthat disrupt securities markets and adversely affect globalmarkets such as war, terrorism, public health crises, andgeopolitical events and by changes in non-U.S. and U.S.economic and political conditions. As a result of theseevents, the Fund could lose money, experience significantredemptions, encounter operational difficulties, and sufferother negative impacts.

— Market Risk – The value of the Fund’s investments will beaffected by fluctuations in the stock markets in which theFund is invested, factors affecting a particular industry orindustries, real or perceived adverse economic conditions,changes in interest or currency rates or adverse investorsentiment generally. Declines in securities market prices mayreduce the net asset value of the Fund’s shares.

— Service Provider Risk – The Fund will be affected by theManager’s investment techniques, analyses, assessmentsand employee retention. Similarly, adverse events orperformance failures at a service provider, such as humanerror, inadequate controls or insolvency, have the ability toadversely affect the Fund.

— Settlement Risk – The Fund may experience delays insettlement due to the different clearance and settlementprocedures in non-U.S. countries. Such delays may increasecredit risk to the Fund, limit the ability of the Fund to reinvestthe proceeds of a sale of securities, or prevent the Fundfrom selling securities at times and prices it considersdesirable.

Baillie Gifford Funds – Prospectus

— Small- and Medium-Capitalization Securities Risk – Securitiesof small- and medium-capitalization companies can be morevolatile due to various factors including more limited productlines, financial and management resources and marketdistribution channels, as well as shorter operating historiesand potentially reduced liquidity, especially during marketdeclines, than the securities of larger, more establishedcompanies.

— Valuation Risk – In certain circumstances, some of theFund’s portfolio holdings may be valued on the basis offactors other than market quotations by employing the fairvalue procedures adopted by the Board of Trustees of theTrust (the “Board”). This may occur more often in times ofmarket turmoil or reduced liquidity. Portfolio holdings that arevalued using techniques other than market quotations,including “fair valued” securities, may be subject to greaterfluctuation in their valuations from one day to the next than ifmarket quotations were used. There is no assurance that theFund could sell or close out a portfolio position for the valueestablished for it at any time, and it is possible that the Fundwould incur a loss because a portfolio position is sold orclosed out at a discount to the valuation established by theFund at that time.

PerformanceThe bar chart and table below provide some indication of therisks of investing in the Fund by showing changes in the Fund’sannual total returns from year to year and by comparing theFund’s average annual total returns with those of the Fund’sbenchmark.

Example of ExpensesThe example below is intended to help you compare the cost ofinvesting in the Fund with the cost of investing in other mutualfunds. It assumes that you invest $10,000 in the Fund for the timeperiods indicated, regardless of whether or not you redeem yourshares at the end of such periods. It also assumes that yourinvestment has a 5% return each year and that the Fund’soperating expenses remain the same.

Although your actual costs may be higher or lower, based onthese assumptions, your expenses would be:

Class K Institutional Class1 Year $82 $913 Years $255 $2845 Years $444 $49310 Years $990 $1,096

Portfolio TurnoverThe Fund pays transaction costs, such as commissions, when itbuys and sells securities (or “turns over” its portfolio). A higherportfolio turnover rate may indicate higher transaction costs andmay result in higher taxes when Fund shares are held in ataxable account. These transaction costs, which are not reflectedin “Annual Fund Operating Expenses” or in the “Example ofExpenses” above, affect the Fund’s performance. During theFund’s most recent fiscal year, the Fund’s portfolio turnover ratewas 24% of the average value of its portfolio.

Principal Investment StrategiesThe Fund seeks to meet its objective by investing in a portfolio ofcommon stocks and other equity securities of issuers located incountries of emerging and frontier markets.

Under normal circumstances, the Fund invests at least 80% of itsnet assets (plus any borrowings for investment purposes) inequity securities of companies located in countries representedin the MSCI Emerging Markets Index. The countries representedin the MSCI Emerging Markets Index include markets that maybe less sophisticated than more developed markets in terms ofparticipation by investors, analyst coverage, liquidity, andregulation. The Fund invests in equity securities either directly orindirectly, such as through depositary receipts or participatorynotes, and may invest in preferred stocks, convertible securitiesand warrants. The Fund is not constrained with respect to marketcapitalization and may participate in initial public offerings(“IPOs”) and in securities offerings that are not registered in theU.S. The portfolio managers have flexibility to gain exposure toone or more emerging markets through investing in exchangetraded funds (“ETFs”) that track relevant equity indices.

The portfolio managers primarily employ a bottom-up approachto stock selection and select companies without beingconstrained by the MSCI Emerging Markets benchmark. Theportfolio managers may reference the benchmark to set limits onthe relative weighting of countries in the portfolio. The portfoliomanagers can also consider macro-economic factors whenidentifying potential investments. The portfolio managers focuson company research and the long-term outlook of companiesand industries. Ideas can come from a wide variety of sources,including, but not limited to, research trips, company meetings,and relationships with industry thought leaders and academicinstitutions. Stock ideas are normally researched to assess arange of factors, including: long-term growth potential,geographic and industry positioning, competitive advantage,management, financial strength and valuation. The intendedoutcome is a diversified portfolio of between 60 and 100 growthcompanies with the potential to outperform the benchmark overthe long term. The process can result in significant exposure to asingle country or a small number of countries, and the Fundexpects to invest significantly in Chinese companies includingthrough China A shares, which are common stocks and otherequity securities that are listed or traded on a Chinese stockexchange and which are quoted in renminbi. The Fund aims tohold securities for long periods (typically 5 years), which resultsin relatively low portfolio turnover and is in line with the Fund’slong-term investment outlook.

The Fund may invest without limitation in securities quoted ordenominated in currencies other than the U.S. dollar and mayhold such currencies. The Fund does not expect to engage incurrency hedging and thus expects to be fully exposed tocurrency fluctuations relative to the U.S. dollar.

Principal RisksThe Fund’s net asset value and returns will be impacted by theperformance of the underlying investments of the Fund. Aninvestment in the Fund is not a deposit in a bank and is notinsured or guaranteed by the Federal Deposit InsuranceCorporation or any other government agency. You could losemoney by investing in the Fund.

Baillie Gifford Funds – Prospectus

The principal risks of investing in the Fund (in alphabetical orderafter the first six risks) are:

— Investment Style Risk – Baillie Gifford Overseas Limited(the “Manager”) actively makes investment decisions for theFund through bottom-up stock selection. Accordingly, theFund will have risk characteristics that differ from itsbenchmark index. The Manager’s judgments about theattractiveness, relative value, or potential appreciation of aparticular stock may prove to be incorrect and cause theFund to lose money or underperform compared to itsbenchmark index. There can be no assurance that theManager’s investment decisions will produce the desiredresults.

— Growth Stock Risk – The prices of growth stocks may bebased largely on expectations of future earnings, and theirprices can decline rapidly and significantly in reaction tonegative news. Growth stocks may underperform stocks inother broad style categories (and the stock market as awhole) over any period of time and may shift in and out offavor with investors generally, sometimes rapidly, dependingon changes in market, economic, and other factors.

— Long-Term Investment Strategy Risk – The Fund pursues along-term investment approach, typically seeking returnsover a period of several years. This investment style maycause the Fund to lose money or underperform compared toits benchmark index or other mutual funds over extendedperiods of time, and the Fund may not perform as expectedin the long term. An investment in the Fund may be moresuitable for long-term investors who can bear the risk ofshort- or medium-term fluctuations in the value of the Fund’sportfolio.

— Geographic Focus Risk – The Fund expects to focus itsinvestments in a limited number of countries or geographicregions, and as a result may not offer the same level ofdiversification of risks as a more broadly global fundbecause the Fund will be exposed to a smaller geographicarea. The performance of a fund that is less diversifiedacross countries or geographic regions will be closely tied tomarket, currency, economic, political, environmental, orregulatory conditions and developments in the countries orregions in which the fund invests, and may be more volatilethan the performance of a more geographically-diversifiedportfolio.

— Emerging Markets Risk – Because the Fund invests inemerging market securities, the Fund may be exposed togreater market, credit, currency, liquidity, legal, political,technical and other risks different from, or greater than, therisks of investing in developed markets.

— Asia Risk – Investing in securities of companies located in orwith exposure to Asian countries involves certain risks andconsiderations not typically associated with investing insecurities of U.S. issuers, including different financialreporting standards, currency exchange rate fluctuations,and highly regulated markets with the potential forgovernment interference. The economies of many Asiancountries are heavily dependent on international trade andon only a few industries or commodities and, as a result, canbe adversely affected by trade barriers, exchange controls

and other measures imposed or negotiated by the countrieswith which they trade. Some Asian securities may be lessliquid than U.S. or other foreign securities. See “China Risk”for additional details.

Additionally, many of the economies of countries in Asia areconsidered emerging market or frontier market economies.These Asian economies are often characterized by highinflation, undeveloped financial service sectors, frequentcurrency fluctuations, devaluations, or restrictions, politicaland social instability, and less efficient markets. See“Emerging Markets Risk” and “Frontier Markets Risk” foradditional details regarding the risks of investing in suchcountries.

— China Risk – Investing in securities of Chinese issuersinvolves certain risks and considerations not typicallyassociated with investing in securities of U.S. issuers,including, among others, more frequent trading suspensionsand government interventions (including by nationalization ofassets), currency exchange rate fluctuations or blockages,limits on the use of brokers and on foreign ownership,different financial reporting standards, higher dependence onexports and international trade, potential for increased tradetariffs, sanctions, embargoes and other trade limitations, andcustody risks. U.S. sanctions or other investment restrictionscould preclude the Fund from investing in certain Chineseissuers or cause the Fund to sell investments at adisadvantageous time. Significant portions of the Chinesesecurities markets may become rapidly illiquid, as Chineseissuers have the ability to suspend the trading of their equitysecurities, and have shown a willingness to exercise thatoption in response to market volatility and other events.

— Conflicts of Interest Risk – The Manager’s relationships withthe Fund’s institutional investor base may give rise to variousconflicts of interest, since the Manager will sometimes havean incentive to favor those shareholders over othershareholders in the Fund. In addition, the Manager serves asinvestment adviser to various clients other than the Fund,some of whom may pursue strategies that are substantiallysimilar or nearly identical to investment strategies pursuedby the Fund. This “side-by-side” management may give riseto various conflicts of interest, including, for example, inconnection with the fair allocation of trades among theManager’s clients or the sharing of different, more, or moretimely information regarding investment performance,portfolio holdings, strategy developments and/or theManager’s general market outlook. Furthermore, ifinvestment personnel of the Manager hold board or otherpositions at outside companies, they could be exposed tomaterial non-public information potentially impeding ordelaying a Fund’s ability to buy or sell certain investments, orthey could otherwise be restricted in their ability toparticipate in a Fund’s investment process.

— Currency Risk – The Fund may realize a loss if it hasexposure to a non-U.S. currency, and this non-U.S. currencydeclines in value, relative to the U.S. dollar. The Fund doesnot expect to engage in currency hedging and thus expectsto be fully exposed to currency fluctuations relative to theU.S. dollar.

Baillie Gifford Funds – Prospectus

— Equity Securities Risk – Equity securities may react morestrongly to changes in an issuer’s financial condition orprospects than other securities of the same issuer. Investingin equity securities indirectly, such as through participatorynotes or depositary receipts, may involve other risks such asthe risk that the counterparty may default or that theinvestment does not track the underlying security asexpected.

— Focused Investment Risk – Should the Fund focus itsinvestments in related, or a limited number of, countries,regions, sectors, or companies, this would create more riskand greater volatility than if the Fund’s investments wereless focused.

— Frontier Markets Risk – Frontier markets are those emergingmarkets that are considered to be among the smallest, leastmature and least liquid and, as a result, may be more volatileand less liquid than investments in more developed marketsor in other emerging market countries. Emerging marketsrisk may be especially heightened in frontier markets.

— Government and Regulatory Risk – Governmental andregulatory authorities in the United States and othercountries, have taken, and may in the future take, actionsintervening in the markets in which the Fund invests and inthe economy more generally. Governmental and regulatoryauthorities may also act to increase the scope or burden ofregulations applicable to the Fund or to the companies inwhich the Fund invests. The effects of these actions on themarkets generally, and Fund’s investment program inparticular, can be uncertain and could restrict the ability ofthe Fund to fully implement its investment strategies, eithergenerally, or with respect to certain securities, industries, orcountries. By contrast, markets in some non-U.S. countrieshistorically have been subject to little regulation or oversightby governmental or regulatory authorities, which couldheighten the risk of loss due to fraud or market failures inthose countries. Governments, agencies, or other regulatorybodies in any country may adopt or change laws orregulations that could adversely affect the Fund or themarket value of an instrument held by the Fund.

— Information Technology Risk – Cyber-attacks, disruptions, orfailures that affect the Fund’s service providers, counterparties,the securities markets generally, other market participants, orissuers of securities held by the Fund may adversely affect theFund and its shareholders, including by causing losses for theFund or impairing Fund operations.

— IPO Risk – The Fund may purchase securities in IPOs.These securities are subject to many of the same risks ofinvesting in companies with smaller market capitalizations.Securities issued in IPOs have no trading history, andinformation about the companies may be available for verylimited periods. In addition, the prices of securities sold inIPOs may be highly volatile.

— Large-Capitalization Securities Risk – Returns oninvestments in securities of large companies could trail thereturns on investments in securities of smaller and medium-sized companies. Larger companies may be unable torespond as quickly as smaller and medium-sized companiesto competitive challenges or to changes in business, product,

financial, or other market conditions. Larger companies maynot be able to achieve or maintain growth at the high ratesthat may be achieved by well-managed smaller and medium-sized companies.

— Liquidity Risk – The Fund’s investments may be subject tolow trading volume, lack of a market maker, contractual lock-in periods or regulatory restrictions, and the Fund may holdlarge positions in particular securities. As a result, it may notbe possible to sell an investment at a particular time or at anacceptable price. Liquidity risk may be magnified duringperiods of changing interest rates, significant shareholderredemptions or market turmoil. Illiquid securities may tradeat a discount from comparable, more liquid investments andmay be subject to wide fluctuations in market value. In somecases, due to unanticipated levels of illiquidity the Fund mayseek to meet its redemption obligations wholly or in part bydistributions of assets in-kind.

— Market Disruption and Geopolitical Risk – The value of theFund’s investments could be adversely affected by eventsthat disrupt securities markets and adversely affect globalmarkets such as war, terrorism, public health crises, andgeopolitical events and by changes in non-U.S. and U.S.economic and political conditions. As a result of theseevents, the Fund could lose money, experience significantredemptions, encounter operational difficulties, and sufferother negative impacts.

— Market Risk – The value of the Fund’s investments will beaffected by fluctuations in the stock markets in which theFund is invested, factors affecting a particular industry orindustries, real or perceived adverse economic conditions,changes in interest or currency rates or adverse investorsentiment generally. Declines in securities market prices mayreduce the net asset value of the Fund’s shares.

— Non-U.S. Investment Risk – Non-U.S. securities are subjectto additional risks, including less liquidity, increased volatility,less transparency, withholding or other taxes, increasedvulnerability to adverse changes in local and globaleconomic conditions, less regulation, and possiblefluctuation in value due to adverse political conditions.Foreign portfolio transactions generally involve highercommission rates, transfer taxes, and custodial costs thansimilar transactions in the U.S.

— Service Provider Risk – The Fund will be affected by theManager’s investment techniques, analyses, assessmentsand employee retention. Similarly, adverse events orperformance failures at a service provider, such as humanerror, inadequate controls or insolvency, have the ability toadversely affect the Fund.

— Settlement Risk – The Fund may experience delays insettlement due to the different clearance and settlementprocedures in non-U.S. countries. Such delays may increasecredit risk to the Fund, limit the ability of the Fund to reinvestthe proceeds of a sale of securities, or prevent the Fund fromselling securities at times and prices it considers desirable.

— Small- and Medium-Capitalization Securities Risk – Securitiesof small- and medium-capitalization companies can be morevolatile due to various factors including more limited product

lines, financial and management resources and marketdistribution channels, as well as shorter operating historiesand potentially reduced liquidity, especially during marketdeclines, than the securities of larger, more establishedcompanies.

— Underlying Funds Risk – Investments in other pooledinvestment vehicles may indirectly expose the Fund to all ofthe risks applicable to an investment in such other pool. TheFund must pay its pro rata portion of the other pooledvehicle’s fees and expenses. If such pool is an ETF or otherproduct traded on a securities exchange or otherwiseactively traded, its shares may trade at a premium ordiscount to their net asset value, an effect that might bemore pronounced in less liquid markets. Further, theManager or an affiliate may serve as investment adviser tosome pooled vehicles in which the Fund invests, leading topotential conflicts of interest.

— Valuation Risk – In certain circumstances, some of theFund’s portfolio holdings may be valued on the basis offactors other than market quotations by employing the fairvalue procedures adopted by the Board of Trustees of theTrust (the “Board”). This may occur more often in times ofmarket turmoil or reduced liquidity. Portfolio holdings that arevalued using techniques other than market quotations,including “fair valued” securities, may be subject to greaterfluctuation in their valuations from one day to the next than ifmarket quotations were used. There is no assurance that theFund could sell or close out a portfolio position for the valueestablished for it at any time, and it is possible that the Fundwould incur a loss because a portfolio position is sold orclosed out at a discount to the valuation established by theFund at that time.

PerformanceThe bar chart and table below provide some indication of therisks of investing in the Fund by showing changes in the Fund’sannual total returns from year to year and by comparing theFund’s average annual total returns with those of the Fund’sbenchmark.

(a) The Management Fee consists of an Advisory Fee and anAdministration and Supervisory Fee paid by the Fund to BaillieGifford Overseas Limited.

(b) Other Expenses differ due to sub-accounting expenses.

Example of ExpensesThe example below is intended to help you compare the cost ofinvesting in the Fund with the cost of investing in other mutualfunds. It assumes that you invest $10,000 in the Fund for the timeperiods indicated, regardless of whether or not you redeem yourshares at the end of such periods. It also assumes that yourinvestment has a 5% return each year and that the Fund’soperating expenses remain the same.

Although your actual costs may be higher or lower, based onthese assumptions, your expenses would be:

Class K Institutional Class1 Year $66 $763 Years $208 $2375 Years $362 $41110 Years $810 $918

Portfolio TurnoverThe Fund pays transaction costs, such as commissions, when itbuys and sells securities (or “turns over” its portfolio). A higherportfolio turnover rate may lead to higher transaction costs andmay result in higher taxes when Fund shares are held in ataxable account. These transaction costs, which are not reflectedin “Annual Fund Operating Expenses” or in the “Example ofExpenses” above, affect the Fund’s performance. During theFund’s most recent fiscal year, the Fund’s portfolio turnover ratewas 23% of the average value of its portfolio.

Principal Investment StrategiesThe Fund seeks to meet its objective by investing in a global,diversified portfolio of equities, which include common stock andother equity securities, of issuers located in countries ofdeveloped and emerging markets.

Under normal circumstances, the Fund invests at least 80% of itsnet assets (plus any borrowings for investment purposes) inequity securities. The Fund invests predominantly in a diversifiedportfolio of securities issued by companies located in countriesrepresented in the MSCI ACWI Index, cash and cash equivalents.The Fund invests in companies whose principal activities are inthe U.S., Canada, Latin America, Europe, Australasia, Africa, theMiddle East and/or the Far East. The Fund ordinarily invests insecurities of issuers located in at least three different countries.In addition, under normal circumstances, the Fund will invest atleast 40% of its total assets in securities of companies locatedoutside the U.S. when market conditions are favorable, but, whenmarket conditions are not favorable, the Fund will invest at least30% of its total assets in companies located outside the U.S. TheFund invests in equity securities either directly or indirectly, suchas through depositary receipts, and may invest in preferredstocks, convertible securities and warrants. The Fund typicallyinvests in issuers with a market capitalization of more than$4 billion at the time of purchase and may participate in initialpublic offerings (“IPOs”) and in securities offerings that are notregistered in the U.S.

The portfolio managers employ a bottom-up approach to stockselection and select companies without being constrained by theMSCI ACWI benchmark. The portfolio managers focus oncompany research and the long-term outlook of companies andindustries. Ideas can come from a wide variety of sources,including, but not limited to, research trips, company meetings,and relationships with industry thought leaders and academicinstitutions. Stock ideas are normally researched to assess arange of factors, including: long-term growth potential,geographic and industry positioning, competitive advantage,management, financial strength and valuation. The intendedoutcome is a diversified portfolio of between 70 and 120 growthcompanies with the potential to outperform the benchmark overthe long term. The process can result in significant exposure to asingle country or a small number of countries. The Fund aims tohold securities for long periods (typically 5 years), which resultsin relatively low portfolio turnover and is in line with the Fund’slong-term investment outlook.

The Fund may invest without limitation in securities quoted ordenominated in currencies other than the U.S. dollar and mayhold such currencies. The Fund does not expect to engage incurrency hedging and thus expects to be fully exposed tocurrency fluctuations relative to the U.S. dollar.

Principal RisksThe Fund’s net asset value and returns will be impacted by theperformance of the underlying investments of the Fund. Aninvestment in the Fund is not a deposit in a bank and is notinsured or guaranteed by the Federal Deposit InsuranceCorporation or any other government agency. You could losemoney by investing in the Fund.

The principal risks of investing in the Fund (in alphabetical orderafter the first four risks) are:

— Investment Style Risk – Baillie Gifford Overseas Limited(the “Manager”) actively makes investment decisions for theFund through bottom-up stock selection. Accordingly, theFund will have risk characteristics that differ from itsbenchmark index. The Manager’s judgments about theattractiveness, relative value, or potential appreciation of aparticular stock may prove to be incorrect and cause theFund to lose money or underperform compared to itsbenchmark index. There can be no assurance that theManager’s investment decisions will produce the desiredresults.

— Growth Stock Risk – The prices of growth stocks may bebased largely on expectations of future earnings, and theirprices can decline rapidly and significantly in reaction tonegative news. Growth stocks may underperform stocks inother broad style categories (and the stock market as awhole) over any period of time and may shift in and out offavor with investors generally, sometimes rapidly, dependingon changes in market, economic, and other factors.

— Long-Term Investment Strategy Risk – The Fund pursues along-term investment approach, typically seeking returnsover a period of several years. This investment style maycause the Fund to lose money or underperform compared toits benchmark index or other mutual funds over extendedperiods of time, and the Fund may not perform as expectedin the long term. An investment in the Fund may be moresuitable for long-term investors who can bear the risk ofshort- or medium-term fluctuations in the value of the Fund’sportfolio.

— Non-U.S. Investment Risk – Non-U.S. securities are subjectto additional risks, including less liquidity, increased volatility,less transparency, withholding or other taxes, increasedvulnerability to adverse changes in local and globaleconomic conditions, less regulation, and possiblefluctuation in value due to adverse political conditions.Foreign portfolio transactions generally involve highercommission rates, transfer taxes, and custodial costs thansimilar transactions in the U.S.

— Asia Risk – Investing in securities of companies located in orwith exposure to Asian countries involves certain risks andconsiderations not typically associated with investing insecurities of U.S. issuers, including different financialreporting standards, currency exchange rate fluctuations,and highly regulated markets with the potential forgovernment interference. The economies of many Asiancountries are heavily dependent on international trade andon only a few industries or commodities and, as a result, canbe adversely affected by trade barriers, exchange controlsand other measures imposed or negotiated by the countrieswith which they trade. Some Asian securities may be lessliquid than U.S. or other foreign securities. See “China Risk”and “Japan Risk” for additional details regarding the risks ofinvesting in those countries.

Additionally, many of the economies of countries in Asia areconsidered emerging market or frontier market economies.These Asian economies are often characterized by high

inflation, undeveloped financial service sectors, frequentcurrency fluctuations, devaluations, or restrictions, politicaland social instability, and less efficient markets. See“Emerging Markets Risk” for additional details regarding therisks of investing in such countries.

— China Risk – Investing in securities of Chinese issuersinvolves certain risks and considerations not typicallyassociated with investing in securities of U.S. issuers,including, among others, more frequent trading suspensionsand government interventions (including by nationalization ofassets), currency exchange rate fluctuations or blockages,limits on the use of brokers and on foreign ownership,different financial reporting standards, higher dependence onexports and international trade, potential for increased tradetariffs, sanctions, embargoes and other trade limitations, andcustody risks. U.S. sanctions or other investment restrictionscould preclude the Fund from investing in certain Chineseissuers or cause the Fund to sell investments at adisadvantageous time. Significant portions of the Chinesesecurities markets may become rapidly illiquid, as Chineseissuers have the ability to suspend the trading of their equitysecurities, and have shown a willingness to exercise thatoption in response to market volatility and other events.

— Conflicts of Interest Risk – The Manager’s relationships withthe Fund’s institutional investor base may give rise to variousconflicts of interest, since the Manager will sometimes havean incentive to favor those shareholders over othershareholders in the Fund. In addition, the Manager serves asinvestment adviser to various clients other than the Fund,some of whom may pursue strategies that are substantiallysimilar or nearly identical to investment strategies pursuedby the Fund. This “side-by-side” management may give riseto various conflicts of interest, including, for example, inconnection with the fair allocation of trades among theManager’s clients or the sharing of different, more, or moretimely information regarding investment performance,portfolio holdings, strategy developments and/or theManager’s general market outlook. Furthermore, ifinvestment personnel of the Manager hold board or otherpositions at outside companies, they could be exposed tomaterial non-public information potentially impeding ordelaying a Fund’s ability to buy or sell certain investments, orthey could otherwise be restricted in their ability toparticipate in a Fund’s investment process.

— Currency Risk – The Fund may realize a loss if it hasexposure to a non-U.S. currency, and this non-U.S. currencydeclines in value, relative to the U.S. dollar. The Fund doesnot expect to engage in currency hedging and thus expectsto be fully exposed to currency fluctuations relative to theU.S. dollar.

— Emerging Markets Risk – To the extent the Fund invests inemerging market securities, the Fund may be exposed togreater market, credit, currency, liquidity, legal, political,technical and other risks different from, or greater than, therisks of investing in developed markets.

— Equity Securities Risk – Equity securities may react morestrongly to changes in an issuer’s financial condition orprospects than other securities of the same issuer. Investing

in equity securities indirectly, such as through participatorynotes or depositary receipts, may involve other risks such asthe risk that the counterparty may default or that theinvestment does not track the underlying security asexpected.

— Focused Investment Risk – Should the Fund focus itsinvestments in related, or a limited number of, countries,regions, sectors, or companies, this would create more riskand greater volatility than if the Fund’s investments wereless focused.

— Government and Regulatory Risk – Governmental andregulatory authorities in the United States and othercountries, have taken, and may in the future take, actionsintervening in the markets in which the Fund invests and inthe economy more generally. Governmental and regulatoryauthorities may also act to increase the scope or burden ofregulations applicable to the Fund or to the companies inwhich the Fund invests. The effects of these actions on themarkets generally, and Fund’s investment program inparticular, can be uncertain and could restrict the ability ofthe Fund to fully implement its investment strategies, eithergenerally, or with respect to certain securities, industries, orcountries. By contrast, markets in some non-U.S. countrieshistorically have been subject to little regulation or oversightby governmental or regulatory authorities, which couldheighten the risk of loss due to fraud or market failures inthose countries. Governments, agencies, or other regulatorybodies in any country may adopt or change laws orregulations that could adversely affect the Fund or themarket value of an instrument held by the Fund.

— Information Technology Risk – Cyber-attacks, disruptions, orfailures that affect the Fund’s service providers, counterparties,the securities markets generally, other market participants, orissuers of securities held by the Fund may adversely affect theFund and its shareholders, including by causing losses for theFund or impairing Fund operations.

— IPO Risk – The Fund may purchase securities in IPOs.These securities are subject to many of the same risks ofinvesting in companies with smaller market capitalizations.Securities issued in IPOs have no trading history, andinformation about the companies may be available for verylimited periods. In addition, the prices of securities sold inIPOs may be highly volatile.

— Japan Risk – The Japanese economy has only recentlyemerged from a prolonged economic downturn. Since theyear 2000, Japan’s economic growth rate has remainedrelatively low, and it may remain low in the future. Japan’seconomy is characterized by an aging demographic,declining population, large government debt, and a highlyregulated labor market. In the longer term, Japan will have toaddress the effects of an aging population, including theimpact of a shrinking work force and higher welfare costs.Japan’s economic recovery has been affected by economicdistress resulting from a number of natural disasters,including disasters that caused damage to nuclear powerplants in the region. Such environmental catastrophes havecaused Japan’s financial markets to fluctuate dramatically.

Japan continues to be subject to the risk of natural disasters,such as earthquakes, volcanic eruptions, typhoons andtsunamis, which could negatively affect the Japaneseeconomy.

— Large-Capitalization Securities Risk – Returns oninvestments in securities of large companies could trail thereturns on investments in securities of smaller and medium-sized companies. Larger companies may be unable torespond as quickly as smaller and medium-sized companiesto competitive challenges or to changes in business, product,financial, or other market conditions. Larger companies maynot be able to achieve or maintain growth at the high ratesthat may be achieved by well-managed smaller and medium-sized companies.

— Liquidity Risk – The Fund’s investments may be subject tolow trading volume, lack of a market maker, contractual lock-in periods or regulatory restrictions, and the Fund may holdlarge positions in particular securities. As a result, it may notbe possible to sell an investment at a particular time or at anacceptable price. Liquidity risk may be magnified duringperiods of changing interest rates, significant shareholderredemptions or market turmoil. Illiquid securities may tradeat a discount from comparable, more liquid investments andmay be subject to wide fluctuations in market value. In somecases, due to unanticipated levels of illiquidity the Fund mayseek to meet its redemption obligations wholly or in part bydistributions of assets in-kind.

— Market Disruption and Geopolitical Risk – The value of theFund’s investments could be adversely affected by eventsthat disrupt securities markets and adversely affect globalmarkets such as war, terrorism, public health crises, andgeopolitical events and by changes in non-U.S. and U.S.economic and political conditions. As a result of theseevents, the Fund could lose money, experience significantredemptions, encounter operational difficulties, and sufferother negative impacts.

— Market Risk – The value of the Fund’s investments will beaffected by fluctuations in the stock markets in which theFund is invested, factors affecting a particular industry orindustries, real or perceived adverse economic conditions,changes in interest or currency rates or adverse investorsentiment generally. Declines in securities market prices mayreduce the net asset value of the Fund’s shares.

— Service Provider Risk – The Fund will be affected by theManager’s investment techniques, analyses, assessmentsand employee retention. Similarly, adverse events orperformance failures at a service provider, such as humanerror, inadequate controls or insolvency, have the ability toadversely affect the Fund.

— Settlement Risk – The Fund may experience delays insettlement due to the different clearance and settlementprocedures in non-U.S. countries. Such delays may increasecredit risk to the Fund, limit the ability of the Fund to reinvestthe proceeds of a sale of securities, or prevent the Fundfrom selling securities at times and prices it considersdesirable.

— Small- and Medium-Capitalization Securities Risk – Securitiesof small- and medium-capitalization companies can be morevolatile due to various factors including more limited productlines, financial and management resources and marketdistribution channels, as well as shorter operating historiesand potentially reduced liquidity, especially during marketdeclines, than the securities of larger, more establishedcompanies.

— Valuation Risk – In certain circumstances, some of theFund’s portfolio holdings may be valued on the basis offactors other than market quotations by employing the fairvalue procedures adopted by the Board of Trustees of theTrust (the “Board”). This may occur more often in times ofmarket turmoil or reduced liquidity. Portfolio holdings that arevalued using techniques other than market quotations,including “fair valued” securities, may be subject to greaterfluctuation in their valuations from one day to the next than ifmarket quotations were used. There is no assurance that theFund could sell or close out a portfolio position for the valueestablished for it at any time, and it is possible that the Fundwould incur a loss because a portfolio position is sold orclosed out at a discount to the valuation established by theFund at that time.

Baillie Gifford Global Stewardship Equities Fund

Investment ObjectiveBaillie Gifford Global Stewardship Equities Fund seeks capitalappreciation.

Fees and ExpensesThe tables below describe the fees and expenses that you maypay if you buy, hold, and sell shares of the Fund. You may payother fees, such as brokerage commissions and other fees tofinancial intermediaries, which are not reflected in the tables andexamples below.

Shareholder Fees(Fees paid directly from your investment)

Class K Institutional ClassNone None

Annual Fund Operating Expenses(Expenses that you pay each year as a percentage of the valueof your investment)

Class K Institutional ClassManagement Fees(a) 0.50% 0.50%Distribution (12b-1) Fees None NoneOther Expenses(b) 4.72% 4.72%Total Annual Fund Operating Expenses 5.22% 5.22%Fee Waiver and/or Expense Reimbursement(c) (4.57)% (4.57)%Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement(c) 0.65% 0.65%

(a) The Management Fee consists of an Advisory Fee and anAdministration and Supervisory Fee paid by the Fund to BaillieGifford Overseas Limited.

(b) While Other Expenses for the last fiscal year were the same forInstitutional Class and Class K, Other Expenses for InstitutionalClass are expected to be higher than those of Class K in the future,since Institutional Class is expected to bear sub-accountingexpenses.

(c) Baillie Gifford Overseas Limited has contractually agreed to waiveits fees and/or bear Other Expenses of the Fund until April 30, 2022to the extent that such Fund’s Total Annual Operating Expenses(excluding taxes, sub-accounting expenses and extraordinaryexpenses) exceed 0.65% for Class K and Institutional Class shares.This contractual agreement may only be terminated by the Board ofTrustees of the Trust. Because this cap of 0.65% excludes sub-accounting expenses, Total Annual Fund Operating Expenses AfterFee Waiver and/or Expense Reimbursement for InstitutionalClass are expected to exceed the cap in the future.

Example of ExpensesThe example below is intended to help you compare the cost ofinvesting in the Fund with the cost of investing in other mutualfunds. It assumes that you invest $10,000 in the Fund for the timeperiods indicated, regardless of whether or not you redeem yourshares at the end of such periods. It also assumes that yourinvestment has a 5% return each year and that the Fund’soperating expenses remain the same. The example below alsoapplies any contractual expense waivers and/or expensereimbursements to the first year of each period listed in the table.

Although your actual costs may be higher or lower, based onthese assumptions, your expenses would be:

Class K Institutional Class1 Year $66 $663 Years $1,153 $1,1535 Years $2,236 $2,23610 Years $4,921 $4,921

Portfolio TurnoverThe Fund pays transaction costs, such as commissions, when itbuys and sells securities (or “turns over” its portfolio). A higherportfolio turnover rate may indicate higher transaction costs andmay result in higher taxes when Fund shares are held in ataxable account. These transaction costs, which are not reflectedin “Annual Fund Operating Expenses” or in the “Example ofExpenses” above, affect the Fund’s performance. During theFund’s most recent fiscal year, the Fund’s portfolio turnover ratewas 17% of the average value of its portfolio.

Principal Investment StrategiesThe Fund seeks to meet its objective by investing in a globalportfolio of equity securities of issuers located in countries withdeveloped and with emerging markets. In seeking to meet itsinvestment objective, the Fund considers stewardship andenvironmental, social, and/or governance (“ESG”) factors.

Under normal circumstances, the Fund invests at least 80% of itsnet assets (plus any borrowings for investment purposes) inequity securities. The Fund invests in equity securities eitherdirectly or indirectly, such as through depositary receipts, andmay invest in preferred stocks, convertible securities andwarrants. The Fund invests predominantly in a diversifiedportfolio of securities issued by companies located in countriesrepresented in the MSCI ACWI Index, cash and cash equivalents.

In addition, under normal circumstances, the Fund will invest atleast 40% of its total assets in securities of companies locatedoutside the U.S. when market conditions are favorable, but, whenmarket conditions are not favorable, will invest at least 30% of itstotal assets in companies located outside the U.S. The Fund’sinvestment universe includes invest in issuers located inemerging markets.

Although the Fund retains the ability to invest in issuers of anymarket capitalization, the Fund typically invests primarily inissuers with a market capitalization of approximately $1.5 billionor more at the time of purchase. The Fund may participate ininitial public offerings (“IPOs”) and in securities offerings that arenot registered in the U.S.

The portfolio managers employ a bottom-up approach to stockselection and select companies without being constrained by theMSCI ACWI benchmark. The portfolio managers focus oncompany research and the long-term outlook of companies andindustries. Ideas can come from a wide variety of sources,including, but not limited to, research trips, company meetings,and relationships with industry thought leaders and academicinstitutions. Stock ideas are normally researched to assess arange of factors, including: long-term growth potential,geographic and industry positioning, competitive advantage,management, financial strength and valuation. The intendedoutcome is a diversified portfolio of between 70 and 90 growth

companies with the potential to outperform the benchmark overthe long term. The process can result in significant exposure to asingle country or a small number of countries, which in recentperiods have included Japan and China. The Fund expects toinvest in Chinese companies, among other means, through ChinaA shares, which are common stocks and other equity securitiesthat are listed or traded on a Chinese stock exchange and whichare quoted in renminbi. The Fund aims to hold securities for longperiods (typically 5 years), which results in relatively low portfolioturnover and is in line with the Fund’s long-term investmentoutlook. Portfolio construction decisions are made by a single,central team, which consists of the individual portfolio managers,alongside members of the Manager’s dedicated Governance andSustainability team. The latter provides specialized input intoconsideration of stewardship and related ESG issues.

In selecting investments for the Fund, the portfolio managementteam conducts a stewardship analysis, which focuses on anumber of different aspects relating to the control, oversight andmanagement of a company. As long-term investors, the portfoliomanagement team takes particular interest in the following areasof a company’s business: (i) its capital structure, articles ofincorporation, and the country or countries of incorporation andlisting, (ii) the treatment and protection of minority shareholders,(iii) the support of and commitment to sustainable businesspractices, (vi) the alignment of interests between management,strategic shareholders and other investors; (v) the compositionand effectiveness of the Board of Directors, the quality andperformance of management, and the remuneration of keyemployees; and (vi) the corporate culture and approach tosustainable business, and the management of relationships withcustomers, employees, suppliers, regulators and the widercommunity. In incorporating stewardship in its investmentprocess, the portfolio management team also performs an ESGanalysis on companies considered for inclusion in the Fund’sportfolio. This analysis is supported by bespoke researchconducted by analysts from members of the Manager’sdedicated Governance and Sustainability team using a range ofdifferent information sources. The ESG analysis is reviewed bythe portfolio managers as part of the discussion of the broaderinvestment case for each current and potential portfolio holding.

The Fund may invest without limitation in securities quoted ordenominated in currencies other than the U.S. dollar and mayhold such currencies. The Fund does not expect to engage incurrency hedging and thus expects to be fully exposed tocurrency fluctuations relative to the U.S. dollar.

Principal RisksThe Fund’s net asset value and returns will be impacted by theperformance of the underlying investments of the Fund. Aninvestment in the Fund is not a deposit in a bank and is notinsured or guaranteed by the Federal Deposit InsuranceCorporation or any other government agency. You could losemoney by investing in the Fund.

The principal risks of investing in the Fund (in alphabetical orderafter the first five risks) are:

— Investment Style Risk – Baillie Gifford Overseas Limited(the “Manager”) actively makes investment decisions for theFund through bottom-up stock selection. Accordingly, theFund will have risk characteristics that differ from its

benchmark index. The Manager’s judgments about theattractiveness, relative value, or potential appreciation of aparticular stock may prove to be incorrect and cause theFund to lose money or underperform compared to itsbenchmark index. There can be no assurance that theManager’s investment decisions will produce the desiredresults.

— Growth Stock Risk – The prices of growth stocks may bebased largely on expectations of future earnings, and theirprices can decline rapidly and significantly in reaction tonegative news. Growth stocks may underperform stocks inother broad style categories (and the stock market as awhole) over any period of time and may shift in and out offavor with investors generally, sometimes rapidly, dependingon changes in market, economic, and other factors.

— Long-Term Investment Strategy Risk – The Fund pursues along-term investment approach, typically seeking returnsover a period of several years. This investment style maycause the Fund to lose money or underperform compared toits benchmark index or other mutual funds over extendedperiods of time, and the Fund may not perform as expectedin the long term. An investment in the Fund may be moresuitable for long-term investors who can bear the risk ofshort- or medium-term fluctuations in the value of the Fund’sportfolio.

— Socially Responsible Investing Risk – The Fund’sincorporation of environmental, social and/or governanceconsiderations in its investment process may cause it tomake different investments than funds that have a similarinvestment universe and/or investment style but that do notincorporate such considerations in their strategy orinvestment processes. As a result, such Fund may foregoopportunities to buy certain securities when it mightotherwise be advantageous to do so, or sell securities whenit might be otherwise disadvantageous for it to do so.

— Non-U.S. Investment Risk – Non-U.S. securities are subjectto additional risks, including less liquidity, increased volatility,less transparency, withholding or other taxes, increasedvulnerability to adverse changes in local and globaleconomic conditions, less regulation, and possiblefluctuation in value due to adverse political conditions.Foreign portfolio transactions generally involve highercommission rates, transfer taxes, and custodial costs thansimilar transactions in the U.S.

— Asia Risk – Investing in securities of companies located in orwith exposure to Asian countries involves certain risks andconsiderations not typically associated with investing insecurities of U.S. issuers, including different financialreporting standards, currency exchange rate fluctuations,and highly regulated markets with the potential forgovernment interference. The economies of many Asiancountries are heavily dependent on international trade andon only a few industries or commodities and, as a result, canbe adversely affected by trade barriers, exchange controlsand other measures imposed or negotiated by the countrieswith which they trade. Some Asian securities may be lessliquid than U.S. or other foreign securities. See “China Risk”and “Japan Risk” for additional details regarding the risks ofinvesting in those countries.

Additionally, many of the economies of countries in Asia areconsidered emerging market or frontier market economies.These Asian economies are often characterized by highinflation, undeveloped financial service sectors, frequentcurrency fluctuations, devaluations, or restrictions, politicaland social instability, and less efficient markets. See“Emerging Markets Risk” for additional details regarding therisks of investing in such countries.

— China Risk – Investing in securities of Chinese issuersinvolves certain risks and considerations not typicallyassociated with investing in securities of U.S. issuers,including, among others, more frequent trading suspensionsand government interventions (including by nationalization ofassets), currency exchange rate fluctuations or blockages,limits on the use of brokers and on foreign ownership,different financial reporting standards, higher dependence onexports and international trade, potential for increased tradetariffs, sanctions, embargoes and other trade limitations, andcustody risks. U.S. sanctions or other investment restrictionscould preclude the Fund from investing in certain Chineseissuers or cause the Fund to sell investments at adisadvantageous time. Significant portions of the Chinesesecurities markets may become rapidly illiquid, as Chineseissuers have the ability to suspend the trading of their equitysecurities, and have shown a willingness to exercise thatoption in response to market volatility and other events.

— Conflicts of Interest Risk – The Manager’s relationships withthe Fund’s institutional investor base may give rise to variousconflicts of interest, since the Manager will sometimes havean incentive to favor those shareholders over othershareholders in the Fund. In addition, the Manager serves asinvestment adviser to various clients other than the Fund,some of whom may pursue strategies that are substantiallysimilar or nearly identical to investment strategies pursuedby the Fund. This “side-by-side” management may give riseto various conflicts of interest, including, for example, inconnection with the fair allocation of trades among theManager’s clients or the sharing of different, more, or moretimely information regarding investment performance,portfolio holdings, strategy developments and/or theManager’s general market outlook. Furthermore, ifinvestment personnel of the Manager hold board or otherpositions at outside companies, they could be exposed tomaterial non-public information potentially impeding ordelaying a Fund’s ability to buy or sell certain investments, orthey could otherwise be restricted in their ability toparticipate in a Fund’s investment process.

— Currency Risk – The Fund may realize a loss if it hasexposure to a non-U.S. currency, and this non-U.S. currencydeclines in value, relative to the U.S. dollar. The Fund doesnot expect to engage in currency hedging and thus expectsto be fully exposed to currency fluctuations relative to theU.S. dollar.

— Emerging Markets Risk – To the extent the Fund invests inemerging market securities, the Fund may be exposed togreater market, credit, currency, liquidity, legal, political,technical and other risks different from, or greater than, therisks of investing in developed markets.

— Equity Securities Risk – Equity securities may react morestrongly to changes in an issuer’s financial condition orprospects than other securities of the same issuer. Investingin equity securities indirectly, such as through participatorynotes or depositary receipts, may involve other risks such asthe risk that the counterparty may default or that theinvestment does not track the underlying security asexpected.

— Focused Investment Risk – Should the Fund focus itsinvestments in related, or a limited number of, countries,regions, sectors, or companies, this would create more riskand greater volatility than if the Fund’s investments wereless focused.

— Government and Regulatory Risk – Governmental andregulatory authorities in the United States and othercountries, have taken, and may in the future take, actionsintervening in the markets in which the Fund invests and inthe economy more generally. Governmental and regulatoryauthorities may also act to increase the scope or burden ofregulations applicable to the Fund or to the companies inwhich the Fund invests. The effects of these actions on themarkets generally, and Fund’s investment program inparticular, can be uncertain and could restrict the ability ofthe Fund to fully implement its investment strategies, eithergenerally, or with respect to certain securities, industries, orcountries. By contrast, markets in some non-U.S. countrieshistorically have been subject to little regulation or oversightby governmental or regulatory authorities, which couldheighten the risk of loss due to fraud or market failures inthose countries. Governments, agencies, or other regulatorybodies in any country may adopt or change laws orregulations that could adversely affect the Fund or themarket value of an instrument held by the Fund.

— Information Technology Risk – Cyber-attacks, disruptions, orfailures that affect the Fund’s service providers, counterparties,the securities markets generally, other market participants, orissuers of securities held by the Fund may adversely affect theFund and its shareholders, including by causing losses for theFund or impairing Fund operations.

— IPO Risk – The Fund may purchase securities in IPOs.These securities are subject to many of the same risks ofinvesting in companies with smaller market capitalizations.Securities issued in IPOs have no trading history, andinformation about the companies may be available for verylimited periods. In addition, the prices of securities sold inIPOs may be highly volatile.

— Japan Risk – The Japanese economy has only recentlyemerged from a prolonged economic downturn. Since theyear 2000, Japan’s economic growth rate has remainedrelatively low, and it may remain low in the future. Japan’seconomy is characterized by an aging demographic,declining population, large government debt, and a highlyregulated labor market. In the longer term, Japan will have toaddress the effects of an aging population, including theimpact of a shrinking work force and higher welfare costs.Japan’s economic recovery has been affected by economicdistress resulting from a number of natural disasters,including disasters that caused damage to nuclear power

plants in the region. Such environmental catastrophes havecaused Japan’s financial markets to fluctuate dramatically.Japan continues to be subject to the risk of natural disasters,such as earthquakes, volcanic eruptions, typhoons andtsunamis, which could negatively affect the Japaneseeconomy.

— Large-Capitalization Securities Risk – Returns oninvestments in securities of large companies could trail thereturns on investments in securities of smaller and medium-sized companies. Larger companies may be unable torespond as quickly as smaller and medium-sized companiesto competitive challenges or to changes in business, product,financial, or other market conditions. Larger companies maynot be able to achieve or maintain growth at the high ratesthat may be achieved by well-managed smaller and medium-sized companies.

— Liquidity Risk – The Fund’s investments may be subject tolow trading volume, lack of a market maker, contractual lock-in periods or regulatory restrictions, and the Fund may holdlarge positions in particular securities. As a result, it may notbe possible to sell an investment at a particular time or at anacceptable price. Liquidity risk may be magnified duringperiods of changing interest rates, significant shareholderredemptions or market turmoil. Illiquid securities may tradeat a discount from comparable, more liquid investments andmay be subject to wide fluctuations in market value. In somecases, due to unanticipated levels of illiquidity the Fund mayseek to meet its redemption obligations wholly or in part bydistributions of assets in-kind.

— Market Disruption and Geopolitical Risk – The value of theFund’s investments could be adversely affected by eventsthat disrupt securities markets and adversely affect globalmarkets such as war, terrorism, public health crises, andgeopolitical events and by changes in non-U.S. and U.S.economic and political conditions. As a result of theseevents, the Fund could lose money, experience significantredemptions, encounter operational difficulties, and sufferother negative impacts.

— Market Risk – The value of the Fund’s investments will beaffected by fluctuations in the stock markets in which theFund is invested, factors affecting a particular industry orindustries, real or perceived adverse economic conditions,changes in interest or currency rates or adverse investorsentiment generally. Declines in securities market prices mayreduce the net asset value of the Fund’s shares.

— New and Smaller-Sized Funds Risk – New funds andsmaller-sized funds will be subject to greater liquidity riskdue to their smaller asset bases and may be required to sellsecurities at disadvantageous times or prices due to a largeshareholder redemption. A fund that has been recentlyformed will have limited or no performance history forinvestors to evaluate and may not reach or maintain asufficient asset size to effectively implement its investmentstrategy.

— Service Provider Risk – The Fund will be affected by theManager’s investment techniques, analyses, assessmentsand employee retention. Similarly, adverse events or

performance failures at a service provider, such as humanerror, inadequate controls or insolvency, have the ability toadversely affect the Fund.

— Settlement Risk – The Fund may experience delays insettlement due to the different clearance and settlementprocedures in non-U.S. countries. Such delays may increasecredit risk to the Fund, limit the ability of the Fund to reinvestthe proceeds of a sale of securities, or prevent the Fundfrom selling securities at times and prices it considersdesirable.

— Small- and Medium-Capitalization Securities Risk – Securitiesof small- and medium-capitalization companies can be morevolatile due to various factors including more limited productlines, financial and management resources and marketdistribution channels, as well as shorter operating historiesand potentially reduced liquidity, especially during marketdeclines, than the securities of larger, more establishedcompanies.

— Valuation Risk – In certain circumstances, some of theFund’s portfolio holdings may be valued on the basis offactors other than market quotations by employing the fairvalue procedures adopted by the Board of Trustees of theTrust (the “Board”). This may occur more often in times ofmarket turmoil or reduced liquidity. Portfolio holdings that arevalued using techniques other than market quotations,including “fair valued” securities, may be subject to greaterfluctuation in their valuations from one day to the next than ifmarket quotations were used. There is no assurance that theFund could sell or close out a portfolio position for the valueestablished for it at any time, and it is possible that the Fundwould incur a loss because a portfolio position is sold orclosed out at a discount to the valuation established by theFund at that time.

Baillie Gifford International Alpha Fund

Investment ObjectiveBaillie Gifford International Alpha Fund seeks capitalappreciation.

Fees and ExpensesThe tables below describe the fees and expenses that you maypay if you buy, hold, and sell shares of the Fund. You may payother fees, such as brokerage commissions and other fees tofinancial intermediaries, which are not reflected in the tables andexamples below.

Shareholder Fees(Fees paid directly from your investment)

Class K Institutional ClassNone None

Annual Fund Operating Expenses(Expenses that you pay each year as a percentage of the valueof your investment)

Class K Institutional ClassManagement Fees(a) 0.51% 0.51%Distribution (12b-1) Fees None NoneOther Expenses(b) 0.08% 0.16%Total Annual Fund Operating Expenses 0.59% 0.67%

(a) The Management Fee consists of an Advisory Fee and anAdministration and Supervisory Fee paid by the Fund to BaillieGifford Overseas Limited.

(b) Other Expenses differ due to sub-accounting expenses.

Example of ExpensesThe example below is intended to help you compare the cost ofinvesting in the Fund with the cost of investing in other mutualfunds. It assumes that you invest $10,000 in the Fund for the timeperiods indicated, regardless of whether or not you redeem yourshares at the end of such periods. It also assumes that yourinvestment has a 5% return each year and that the Fund’soperating expenses remain the same.

Although your actual costs may be higher or lower, based onthese assumptions, your expenses would be:

Class K Institutional Class1 Year $60 $683 Years $189 $2145 Years $329 $37310 Years $738 $835

Portfolio TurnoverThe Fund pays transaction costs, such as commissions, when itbuys and sells securities (or “turns over” its portfolio). A higherportfolio turnover rate may indicate higher transaction costs andmay result in higher taxes when Fund shares are held in ataxable account. These transaction costs, which are not reflectedin “Annual Fund Operating Expenses” or in the “Example ofExpenses” above, affect the Fund’s performance. During theFund’s most recent fiscal year, the Fund’s portfolio turnover ratewas 24% of the average value of its portfolio.

Principal Investment StrategiesThe Fund seeks to meet its objective by investing in aninternational portfolio of equities, which include common stockand other equity securities, of issuers located in countries ofdeveloped and emerging markets.

Under normal circumstances, the Fund invests at least 80% of itsnet assets (plus any borrowings for investment purposes) incommon stocks and other equity securities. The Fund investspredominantly in securities issued by companies located incountries represented in the MSCI ACWI (ex U.S.) Index, whichincludes issuers from a range of developed and emerging marketcountries. The Fund ordinarily invests in securities of issuerslocated in at least three countries outside the U.S. The Fundinvests in equity securities either directly or indirectly, such asthrough depositary receipts, and may invest in preferred stocks,convertible securities and warrants. The Fund is not constrainedwith respect to market capitalization and may participate in initialpublic offerings (“IPOs”) and in securities offerings that are notregistered in the U.S.

The portfolio managers employ a bottom-up approach to stockselection and principally select companies without beingconstrained by the MSCI ACWI (ex U.S.) benchmark. Theportfolio managers focus on company research and the long-term outlook of companies and industries. Ideas can come froma wide variety of sources, including, but not limited to, researchtrips, company meetings, and relationships with industry thoughtleaders and academic institutions. Stock ideas are normallyresearched to assess a range of factors, including: long-termgrowth potential, geographic and industry positioning, competitiveadvantage, management, financial strength and valuation. Theintended outcome is a diversified portfolio of between 70 and110 growth companies with the potential to outperform thebenchmark over the long term. The process can result insignificant exposure to a single country or a small number ofcountries, which in recent periods have included Japan andChina. The Fund expects to invest in Chinese companies, amongother means, through China A shares, which are common stocksand other equity securities that are listed or traded on a Chinesestock exchange and which are quoted in renminbi. The Fundaims to hold securities for long periods (typically 5 years), whichresults in relatively low portfolio turnover and is in line with theFund’s long-term investment outlook.

The Fund may invest without limitation in securities quoted ordenominated in currencies other than the U.S. dollar and mayhold such currencies. The Fund does not expect to engage incurrency hedging and thus expects to be fully exposed tocurrency fluctuations relative to the U.S. dollar.

Principal RisksThe Fund’s net asset value and returns will be impacted by theperformance of the underlying investments of the Fund. Aninvestment in the Fund is not a deposit in a bank and is notinsured or guaranteed by the Federal Deposit InsuranceCorporation or any other government agency. You could losemoney by investing in the Fund.

The principal risks of investing in the Fund (in alphabetical orderafter the first four risks) are:

— Investment Style Risk – Baillie Gifford Overseas Limited(the “Manager”) actively makes investment decisions for the

Fund through bottom-up stock selection. Accordingly, theFund will have risk characteristics that differ from itsbenchmark index. The Manager’s judgments about theattractiveness, relative value, or potential appreciation of aparticular stock may prove to be incorrect and cause theFund to lose money or underperform compared to itsbenchmark index. There can be no assurance that theManager’s investment decisions will produce the desiredresults.

— Growth Stock Risk – The prices of growth stocks may bebased largely on expectations of future earnings, and theirprices can decline rapidly and significantly in reaction tonegative news. Growth stocks may underperform stocks inother broad style categories (and the stock market as awhole) over any period of time and may shift in and out offavor with investors generally, sometimes rapidly, dependingon changes in market, economic, and other factors.

— Long-Term Investment Strategy Risk – The Fund pursues along-term investment approach, typically seeking returnsover a period of several years. This investment style maycause the Fund to lose money or underperform compared toits benchmark index or other mutual funds over extendedperiods of time, and the Fund may not perform as expectedin the long term. An investment in the Fund may be moresuitable for long-term investors who can bear the risk ofshort- or medium-term fluctuations in the value of the Fund’sportfolio.

— Non-U.S. Investment Risk – Non-U.S. securities are subjectto additional risks, including less liquidity, increased volatility,less transparency, withholding or other taxes, increasedvulnerability to adverse changes in local and globaleconomic conditions, less regulation, and possiblefluctuation in value due to adverse political conditions.Foreign portfolio transactions generally involve highercommission rates, transfer taxes, and custodial costs thansimilar transactions in the U.S.

— Asia Risk – Investing in securities of companies located in orwith exposure to Asian countries involves certain risks andconsiderations not typically associated with investing insecurities of U.S. issuers, including different financialreporting standards, currency exchange rate fluctuations,and highly regulated markets with the potential forgovernment interference. The economies of many Asiancountries are heavily dependent on international trade andon only a few industries or commodities and, as a result, canbe adversely affected by trade barriers, exchange controlsand other measures imposed or negotiated by the countrieswith which they trade. Some Asian securities may be lessliquid than U.S. or other foreign securities. See “China Risk”and “Japan Risk” for additional details regarding the risks ofinvesting in those countries.

Additionally, many of the economies of countries in Asia areconsidered emerging market or frontier market economies.These Asian economies are often characterized by highinflation, undeveloped financial service sectors, frequentcurrency fluctuations, devaluations, or restrictions, politicaland social instability, and less efficient markets. See

“Emerging Markets Risk” for additional details regarding therisks of investing in such countries.

— China Risk – Investing in securities of Chinese issuersinvolves certain risks and considerations not typicallyassociated with investing in securities of U.S. issuers,including, among others, more frequent trading suspensionsand government interventions (including by nationalization ofassets), currency exchange rate fluctuations or blockages,limits on the use of brokers and on foreign ownership,different financial reporting standards, higher dependence onexports and international trade, potential for increased tradetariffs, sanctions, embargoes and other trade limitations, andcustody risks. U.S. sanctions or other investment restrictionscould preclude the Fund from investing in certain Chineseissuers or cause the Fund to sell investments at adisadvantageous time. Significant portions of the Chinesesecurities markets may become rapidly illiquid, as Chineseissuers have the ability to suspend the trading of their equitysecurities, and have shown a willingness to exercise thatoption in response to market volatility and other events.

— Conflicts of Interest Risk – The Manager’s relationships withthe Fund’s institutional investor base may give rise to variousconflicts of interest, since the Manager will sometimes havean incentive to favor those shareholders over othershareholders in the Fund. In addition, the Manager serves asinvestment adviser to various clients other than the Fund,some of whom may pursue strategies that are substantiallysimilar or nearly identical to investment strategies pursuedby the Fund. This “side-by-side” management may give riseto various conflicts of interest, including, for example, inconnection with the fair allocation of trades among theManager’s clients or the sharing of different, more, or moretimely information regarding investment performance,portfolio holdings, strategy developments and/or theManager’s general market outlook. Furthermore, ifinvestment personnel of the Manager hold board or otherpositions at outside companies, they could be exposed tomaterial non-public information potentially impeding ordelaying a Fund’s ability to buy or sell certain investments, orthey could otherwise be restricted in their ability toparticipate in a Fund’s investment process.

— Currency Risk – The Fund may realize a loss if it hasexposure to a non-U.S. currency, and this non-U.S. currencydeclines in value, relative to the U.S. dollar. The Fund doesnot expect to engage in currency hedging and thus expectsto be fully exposed to currency fluctuations relative to theU.S. dollar.

— Focused Investment Risk – Should the Fund focus itsinvestments in related, or a limited number of, countries,regions, sectors, or companies, this would create more riskand greater volatility than if the Fund’s investments wereless focused.

— Geographic Focus Risk – The Fund expects to focus itsinvestments in a limited number of countries or geographicregions, and as a result may not offer the same level ofdiversification of risks as a more broadly global fundbecause the Fund will be exposed to a smaller geographicarea. The performance of a fund that is less diversifiedacross countries or geographic regions will be closely tied tomarket, currency, economic, political, environmental, orregulatory conditions and developments in the countries orregions in which the fund invests, and may be more volatilethan the performance of a more geographically-diversifiedportfolio.

— Government and Regulatory Risk – Governmental andregulatory authorities in the United States and othercountries, have taken, and may in the future take, actionsintervening in the markets in which the Fund invests and inthe economy more generally. Governmental and regulatoryauthorities may also act to increase the scope or burden ofregulations applicable to the Fund or to the companies inwhich the Fund invests. The effects of these actions on themarkets generally, and Fund’s investment program inparticular, can be uncertain and could restrict the ability ofthe Fund to fully implement its investment strategies, eithergenerally, or with respect to certain securities, industries, orcountries. By contrast, markets in some non-U.S. countrieshistorically have been subject to little regulation or oversightby governmental or regulatory authorities, which couldheighten the risk of loss due to fraud or market failures inthose countries. Governments, agencies, or other regulatorybodies in any country may adopt or change laws orregulations that could adversely affect the Fund or themarket value of an instrument held by the Fund.

— Information Technology Risk – Cyber-attacks, disruptions, orfailures that affect the Fund’s service providers, counterparties,the securities markets generally, other market participants, orissuers of securities held by the Fund may adversely affect theFund and its shareholders, including by causing losses for theFund or impairing Fund operations.

In addition, the prices of securities sold inIPOs may be highly volatile.

— Japan Risk – The Japanese economy has only recentlyemerged from a prolonged economic downturn. Since theyear 2000, Japan’s economic growth rate has remainedrelatively low, and it may remain low in the future. Japan’seconomy is characterized by an aging demographic,

declining population, large government debt, and a highlyregulated labor market. In the longer term, Japan will have toaddress the effects of an aging population, including theimpact of a shrinking work force and higher welfare costs.Japan’s economic recovery has been affected by economicdistress resulting from a number of natural disasters,including disasters that caused damage to nuclear powerplants in the region. Such environmental catastrophes havecaused Japan’s financial markets to fluctuate dramatically.Japan continues to be subject to the risk of natural disasters,such as earthquakes, volcanic eruptions, typhoons andtsunamis, which could negatively affect the Japaneseeconomy.

— Large-Capitalization Securities Risk – Returns oninvestments in securities of large companies could trail thereturns on investments in securities of smaller and medium-sized companies. Larger companies may be unable torespond as quickly as smaller and medium-sized companiesto competitive challenges or to changes in business, product,financial, or other market conditions.

— Settlement Risk – The Fund may experience delays insettlement due to the different clearance and settlementprocedures in non-U.S. countries. Such delays may increasecredit risk to the Fund, limit the ability of the Fund to reinvestthe proceeds of a sale of securities, or prevent the Fundfrom selling securities at times and prices it considersdesirable.

— Small- and Medium-Capitalization Securities Risk – Securitiesof small- and medium-capitalization companies can be morevolatile due to various factors including more limited productlines, financial and management resources and marketdistribution channels, as well as shorter operating historiesand potentially reduced liquidity, especially during marketdeclines, than the securities of larger, more establishedcompanies.

— Valuation Risk – In certain circumstances, some of theFund’s portfolio holdings may be valued on the basis offactors other than market quotations by employing the fairvalue procedures adopted by the Board of Trustees of theTrust (the “Board”). This may occur more often in times ofmarket turmoil or reduced liquidity. Portfolio holdings that arevalued using techniques other than market quotations,including “fair valued” securities, may be subject to greaterfluctuation in their valuations from one day to the next than ifmarket quotations were used. There is no assurance that theFund could sell or close out a portfolio position for the valueestablished for it at any time, and it is possible that the Fundwould incur a loss because a portfolio position is sold orclosed out at a discount to the valuation established by theFund at that time.

PerformanceThe bar chart and table below provide some indication of therisks of investing in the Fund by showing changes in the Fund’sannual total returns from year to year and by comparing theFund’s average annual total returns with those of the Fund’sbenchmark. Past performance (before and after taxes) is not anindication of future performance.

Annual Total Returns – Institutional Class Shares(1)

Highest Quarterly Return: 25.58% (Q2, 2020)Lowest Quarterly Return: -20.84% (Q1, 2020)

Baillie Gifford International Concentrated Growth EquitiesFund

Investment ObjectiveBaillie Gifford International Concentrated Growth Equities Fundseeks capital appreciation.

Fees and ExpensesThe tables below describe the fees and expenses that you maypay if you buy, hold, and sell shares of the Fund. You may payother fees, such as brokerage commissions and other fees tofinancial intermediaries, which are not reflected in the tables andexamples below.

Shareholder Fees(Fees paid directly from your investment)

Class K Institutional ClassNone None

Annual Fund Operating Expenses(Expenses that you pay each year as a percentage of the valueof your investment)

Class K Institutional ClassManagement Fees(a) 0.57% 0.57%Distribution (12b-1) Fees None NoneOther Expenses 0.22% 0.30%Total Annual Fund Operating Expenses 0.79% 0.87%Fee Waiver and/or Expense Reimbursement(b) (0.07)% (0.07)%Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement(b) 0.72% 0.80%

(a) The Management Fee consists of an Advisory Fee and anAdministration and Supervisory Fee paid by the Fund to BaillieGifford Overseas Limited.

(b) Baillie Gifford Overseas Limited has contractually agreed to waiveits fees and/or bear Other Expenses of the Fund until April 30, 2022to the extent that such Fund’s Total Annual Operating Expenses(excluding taxes, sub-accounting expenses and extraordinaryexpenses) exceed 0.72% for Class K and Institutional Class shares.This contractual agreement may only be terminated by the Board ofTrustees of the Trust. Expenses after waiver/reimbursementexceed 0.72% for Institutional Class due to sub-accountingexpenses of 0.08%.

Example of ExpensesThe example below is intended to help you compare the cost ofinvesting in the Fund with the cost of investing in other mutualfunds. It assumes that you invest $10,000 in the Fund for the timeperiods indicated, regardless of whether or not you redeem yourshares at the end of such periods. It also assumes that yourinvestment has a 5% return each year and that the Fund’soperating expenses remain the same. The example below alsoapplies any contractual expense waivers and/or expensereimbursements to the first year of each period listed in the table.

Although your actual costs may be higher or lower, based onthese assumptions, your expenses would be:

Class K Institutional Class1 Year $74 $823 Years $245 $2715 Years $432 $47510 Years $971 $1,066

Portfolio TurnoverThe Fund pays transaction costs, such as commissions, when itbuys and sells securities (or “turns over” its portfolio). A higherportfolio turnover rate may indicate higher transaction costs andmay result in higher taxes when Fund shares are held in ataxable account. These transaction costs, which are not reflectedin “Annual Fund Operating Expenses” or in the “Example ofExpenses” above, affect the Fund’s performance. During theFund’s most recent fiscal year, the Fund’s portfolio turnover ratewas 59% of the average value of its portfolio.

Principal Investment StrategiesThe Fund seeks to meet its objective by investing in aninternational portfolio of common stocks and other equitysecurities of issuers located in countries of developed andemerging markets.

Under normal circumstances, the Fund invests at least 80% of itsnet assets (plus any borrowings for investment purposes) inequity securities. The Fund may invest up to 20% of its netassets in common stocks and other equities of companieslocated in the U.S. The Fund invests in equity securities eitherdirectly or indirectly, such as through depositary receipts, andmay invest in preferred stocks, convertible securities andwarrants. The Fund is not constrained with respect to marketcapitalization and may participate in initial public offerings(“IPOs”) and in securities offerings that are not registered in theU.S.

The portfolio managers employ a bottom-up approach to stockselection and principally select companies without beingconstrained by the MSCI ACWI (ex U.S.) benchmark. Theportfolio managers focus on company research and the long-term outlook of companies and industries. Ideas can come froma wide variety of sources, including, but not limited to, researchtrips, company meetings, and relationships with industry thoughtleaders and academic institutions. Stock ideas are normallyresearched to assess a range of factors, including: long-termgrowth potential, geographic and industry positioning, competitiveadvantage, management, financial strength and valuation. Theintended outcome is a portfolio of between 20 and 35 growthcompanies with the potential to outperform the benchmark overthe long term. The process can result in significant exposure to asingle country or a small number of countries, which in recentperiods have included Japan and China. The Fund expects tohave considerable exposure to Chinese companies, includingthrough China A shares, which are common stocks and otherequity securities that are listed or traded on a Chinese stockexchange and which are quoted in renminbi. The Fund is a non-diversified fund, which means that it may invest a relatively largepercentage of its assets in a small number of issuers, industries,or sectors. The Fund aims to hold securities for long periods(typically 5-10 years), which results in relatively low portfolio

turnover and is in line with the Fund’s long-term investmentoutlook.

The Fund may invest without limitation in securities quoted ordenominated in currencies other than the U.S. dollar and mayhold such currencies. The Fund does not expect to engage incurrency hedging and thus expects to be fully exposed tocurrency fluctuations relative to the U.S. dollar.

Principal RisksThe Fund’s net asset value and returns will be impacted by theperformance of the underlying investments of the Fund. Aninvestment in the Fund is not a deposit in a bank and is notinsured or guaranteed by the Federal Deposit InsuranceCorporation or any other government agency. You could losemoney by investing in the Fund.

The principal risks of investing in the Fund (in alphabetical orderafter the first six risks) are:

— Investment Style Risk – Baillie Gifford Overseas Limited(the “Manager”) actively makes investment decisions for theFund through bottom-up stock selection. Accordingly, theFund will have risk characteristics that differ from itsbenchmark index. The Manager’s judgments about theattractiveness, relative value, or potential appreciation of aparticular stock may prove to be incorrect and cause theFund to lose money or underperform compared to itsbenchmark index. There can be no assurance that theManager’s investment decisions will produce the desiredresults.

— Growth Stock Risk – The prices of growth stocks may bebased largely on expectations of future earnings, and theirprices can decline rapidly and significantly in reaction tonegative news. Growth stocks may underperform stocks inother broad style categories (and the stock market as awhole) over any period of time and may shift in and out offavor with investors generally, sometimes rapidly, dependingon changes in market, economic, and other factors.

— Long-Term Investment Strategy Risk – The Fund pursues along-term investment approach, typically seeking returnsover a period of several years. This investment style maycause the Fund to lose money or underperform compared toits benchmark index or other mutual funds over extendedperiods of time, and the Fund may not perform as expectedin the long term. An investment in the Fund may be moresuitable for long-term investors who can bear the risk ofshort- or medium-term fluctuations in the value of the Fund’sportfolio.

— Non-U.S. Investment Risk – Non-U.S. securities are subjectto additional risks, including less liquidity, increased volatility,less transparency, withholding or other taxes, increasedvulnerability to adverse changes in local and globaleconomic conditions, less regulation, and possiblefluctuation in value due to adverse political conditions.Foreign portfolio transactions generally involve highercommission rates, transfer taxes, and custodial costs thansimilar transactions in the U.S.

— Non-Diversification Risk – The Fund is classified as a “non-diversified” fund. Because the Fund may invest a relatively

large percentage of its assets in a single issuer or smallnumber of issuers, its performance could be closely tied tothe value of that one issuer or those few issuers, and couldbe more volatile than the performance of diversified funds.

— Asia Risk – Investing in securities of companies located in orwith exposure to Asian countries involves certain risks andconsiderations not typically associated with investing insecurities of U.S. issuers, including different financialreporting standards, currency exchange rate fluctuations,and highly regulated markets with the potential forgovernment interference. The economies of many Asiancountries are heavily dependent on international trade andon only a few industries or commodities and, as a result, canbe adversely affected by trade barriers, exchange controlsand other measures imposed or negotiated by the countrieswith which they trade. Some Asian securities may be lessliquid than U.S. or other foreign securities. See “China Risk”and “Japan Risk” for additional details regarding the risks ofinvesting in those countries.

Additionally, many of the economies of countries in Asia areconsidered emerging market or frontier market economies.These Asian economies are often characterized by highinflation, undeveloped financial service sectors, frequentcurrency fluctuations, devaluations, or restrictions, politicaland social instability, and less efficient markets. See“Emerging Markets Risk” for additional details regarding therisks of investing in such countries.

— China Risk – Investing in securities of Chinese issuersinvolves certain risks and considerations not typicallyassociated with investing in securities of U.S. issuers,including, among others, more frequent trading suspensionsand government interventions (including by nationalization ofassets), currency exchange rate fluctuations or blockages,limits on the use of brokers and on foreign ownership,different financial reporting standards, higher dependence onexports and international trade, potential for increased tradetariffs, sanctions, embargoes and other trade limitations, andcustody risks. U.S. sanctions or other investment restrictionscould preclude the Fund from investing in certain Chineseissuers or cause the Fund to sell investments at adisadvantageous time. Significant portions of the Chinesesecurities markets may become rapidly illiquid, as Chineseissuers have the ability to suspend the trading of their equitysecurities, and have shown a willingness to exercise thatoption in response to market volatility and other events.

— Conflicts of Interest Risk – The Manager’s relationships withthe Fund’s institutional investor base may give rise to variousconflicts of interest, since the Manager will sometimes havean incentive to favor those shareholders over othershareholders in the Fund. In addition, the Manager serves asinvestment adviser to various clients other than the Fund,some of whom may pursue strategies that are substantiallysimilar or nearly identical to investment strategies pursuedby the Fund. This “side-by-side” management may give riseto various conflicts of interest, including, for example, inconnection with the fair allocation of trades among theManager’s clients or the sharing of different, more, or moretimely information regarding investment performance,portfolio holdings, strategy developments and/or the

Manager’s general market outlook. Furthermore, ifinvestment personnel of the Manager hold board or otherpositions at outside companies, they could be exposed tomaterial non-public information potentially impeding ordelaying a Fund’s ability to buy or sell certain investments, orthey could otherwise be restricted in their ability toparticipate in a Fund’s investment process.

— Currency Risk – The Fund may realize a loss if it hasexposure to a non-U.S. currency, and this non-U.S. currencydeclines in value, relative to the U.S. dollar. The Fund doesnot expect to engage in currency hedging and thus expectsto be fully exposed to currency fluctuations relative to theU.S. dollar.

— Emerging Markets Risk – To the extent the Fund invests inemerging market securities, the Fund may be exposed togreater market, credit, currency, liquidity, legal, political,technical and other risks different from, or greater than, therisks of investing in developed markets.

— Equity Securities Risk – Equity securities may react morestrongly to changes in an issuer’s financial condition orprospects than other securities of the same issuer. Investingin equity securities indirectly, such as through participatorynotes or depositary receipts, may involve other risks such asthe risk that the counterparty may default or that theinvestment does not track the underlying security asexpected.

— Focused Investment Risk – Because the Fund focuses itsinvestments in a limited number of companies, its investmentstrategy could result in more risk or greater volatility inreturns than if the Fund’s investments were less focused.

— Geographic Focus Risk – The Fund expects to focus itsinvestments in a limited number of countries or geographicregions, and as a result may not offer the same level ofdiversification of risks as a more broadly global fundbecause the Fund will be exposed to a smaller geographicarea. The performance of a fund that is less diversifiedacross countries or geographic regions will be closely tied tomarket, currency, economic, political, environmental, orregulatory conditions and developments in the countries orregions in which the fund invests, and may be more volatilethan the performance of a more geographically-diversifiedportfolio.

— Government and Regulatory Risk – Governmental andregulatory authorities in the United States and othercountries, have taken, and may in the future take, actionsintervening in the markets in which the Fund invests and inthe economy more generally. Governmental and regulatoryauthorities may also act to increase the scope or burden ofregulations applicable to the Fund or to the companies inwhich the Fund invests. The effects of these actions on themarkets generally, and Fund’s investment program inparticular, can be uncertain and could restrict the ability ofthe Fund to fully implement its investment strategies, eithergenerally, or with respect to certain securities, industries, orcountries. By contrast, markets in some non-U.S. countrieshistorically have been subject to little regulation or oversightby governmental or regulatory authorities, which couldheighten the risk of loss due to fraud or market failures in

those countries. Governments, agencies, or other regulatorybodies in any country may adopt or change laws orregulations that could adversely affect the Fund or themarket value of an instrument held by the Fund.

— Information Technology Risk – Cyber-attacks, disruptions, orfailures that affect the Fund’s service providers, counterparties,the securities markets generally, other market participants, orissuers of securities held by the Fund may adversely affect theFund and its shareholders, including by causing losses for theFund or impairing Fund operations.

— IPO Risk – The Fund may purchase securities in IPOs.These securities are subject to many of the same risks ofinvesting in companies with smaller market capitalizations.Securities issued in IPOs have no trading history, andinformation about the companies may be available for verylimited periods. In addition, the prices of securities sold inIPOs may be highly volatile.

— Japan Risk – The Japanese economy has only recentlyemerged from a prolonged economic downturn. Since theyear 2000, Japan’s economic growth rate has remainedrelatively low, and it may remain low in the future. Japan’seconomy is characterized by an aging demographic,declining population, large government debt, and a highlyregulated labor market. In the longer term, Japan will have toaddress the effects of an aging population, including theimpact of a shrinking work force and higher welfare costs.Japan’s economic recovery has been affected by economicdistress resulting from a number of natural disasters,including disasters that caused damage to nuclear powerplants in the region. Such environmental catastrophes havecaused Japan’s financial markets to fluctuate dramatically.Japan continues to be subject to the risk of natural disasters,such as earthquakes, volcanic eruptions, typhoons andtsunamis, which could negatively affect the Japaneseeconomy.

— Large-Capitalization Securities Risk – Returns oninvestments in securities of large companies could trail thereturns on investments in securities of smaller and medium-sized companies. Larger companies may be unable torespond as quickly as smaller and medium-sized companiesto competitive challenges or to changes in business, product,financial, or other market conditions. Larger companies maynot be able to achieve or maintain growth at the high ratesthat may be achieved by well-managed smaller and medium-sized companies.

— Liquidity Risk – The Fund’s investments may be subject tolow trading volume, lack of a market maker, contractual lock-in periods or regulatory restrictions, and the Fund may holdlarge positions in particular securities. As a result, it may notbe possible to sell an investment at a particular time or at anacceptable price. Liquidity risk may be magnified duringperiods of changing interest rates, significant shareholderredemptions or market turmoil. Illiquid securities may tradeat a discount from comparable, more liquid investments andmay be subject to wide fluctuations in market value. In somecases, due to unanticipated levels of illiquidity the Fund mayseek to meet its redemption obligations wholly or in part bydistributions of assets in-kind.

Baillie Gifford Funds – Prospectus

— Market Disruption and Geopolitical Risk – The value of theFund’s investments could be adversely affected by eventsthat disrupt securities markets and adversely affect globalmarkets such as war, terrorism, public health crises, andgeopolitical events and by changes in non-U.S. and U.S.economic and political conditions. As a result of theseevents, the Fund could lose money, experience significantredemptions, encounter operational difficulties, and sufferother negative impacts.

— Market Risk – The value of the Fund’s investments will beaffected by fluctuations in the stock markets in which theFund is invested, factors affecting a particular industry orindustries, real or perceived adverse economic conditions,changes in interest or currency rates or adverse investorsentiment generally. Declines in securities market prices mayreduce the net asset value of the Fund’s shares.

— New and Smaller-Sized Funds Risk – New funds andsmaller-sized funds will be subject to greater liquidity riskdue to their smaller asset bases and may be required to sellsecurities at disadvantageous times or prices due to a largeshareholder redemption. A fund that has been recentlyformed will have limited or no performance history forinvestors to evaluate and may not reach or maintain asufficient asset size to effectively implement its investmentstrategy.

— Service Provider Risk – The Fund will be affected by theManager’s investment techniques, analyses, assessmentsand employee retention. Similarly, adverse events orperformance failures at a service provider, such as humanerror, inadequate controls or insolvency, have the ability toadversely affect the Fund.

— Settlement Risk – The Fund may experience delays insettlement due to the different clearance and settlementprocedures in non-U.S. countries. Such delays may increasecredit risk to the Fund, limit the ability of the Fund to reinvestthe proceeds of a sale of securities, or prevent the Fundfrom selling securities at times and prices it considersdesirable.

— Small- and Medium-Capitalization Securities Risk – Securitiesof small- and medium-capitalization companies can be morevolatile due to various factors including more limited productlines, financial and management resources and marketdistribution channels, as well as shorter operating historiesand potentially reduced liquidity, especially during marketdeclines, than the securities of larger, more establishedcompanies.

— Valuation Risk – In certain circumstances, some of theFund’s portfolio holdings may be valued on the basis offactors other than market quotations by employing the fairvalue procedures adopted by the Board of Trustees of theTrust (the “Board”). This may occur more often in times ofmarket turmoil or reduced liquidity. Portfolio holdings that arevalued using techniques other than market quotations,including “fair valued” securities, may be subject to greaterfluctuation in their valuations from one day to the next than ifmarket quotations were used. There is no assurance that theFund could sell or close out a portfolio position for the valueestablished for it at any time, and it is possible that the Fund

would incur a loss because a portfolio position is sold orclosed out at a discount to the valuation established by theFund at that time.

PerformanceThe bar chart and table below provide some indication of therisks of investing in the Fund by showing changes in the Fund’sannual total returns from year to year and by comparing theFund’s average annual total returns with those of the Fund’sbenchmark. Past performance (before and after taxes) is not anindication of future performance.

Annual Total Returns – Institutional Class Shares

Highest Quarterly Return: 44.43% (Q2, 2020)Lowest Quarterly Return: -19.48% (Q4, 2018)

After-taxreturns are shown for Institutional Class shares only, and after-tax returns for other share classes will vary. Actual after-taxreturns depend on your tax situation and may differ from thoseshown.

Baillie Gifford International Growth Fund

Investment ObjectiveBaillie Gifford International Growth Fund seeks capitalappreciation.

Fees and ExpensesThe tables below describe the fees and expenses that you maypay if you buy, hold, and sell shares of the Fund. You may payother fees, such as brokerage commissions and other fees tofinancial intermediaries, which are not reflected in the tables andexamples below.

Shareholder Fees(Fees paid directly from your investment)

Class K Institutional ClassNone None

Annual Fund Operating Expenses(Expenses that you pay each year as a percentage of the valueof your investment)

Class K Institutional ClassManagement Fees(a) 0.50% 0.50%Distribution (12b-1) Fees None NoneOther Expenses(b) 0.08% 0.14%Total Annual Fund Operating Expenses 0.58% 0.64%

(a) The Management Fee consists of an Advisory Fee and anAdministration and Supervisory Fee paid by the Fund to BaillieGifford Overseas Limited.

(b) Other Expenses differ due to sub-accounting expenses.

Example of ExpensesThe example below is intended to help you compare the cost ofinvesting in the Fund with the cost of investing in other mutualfunds. It assumes that you invest $10,000 in the Fund for the timeperiods indicated, regardless of whether or not you redeem yourshares at the end of such periods. It also assumes that yourinvestment has a 5% return each year and that the Fund’soperating expenses remain the same.

Although your actual costs may be higher or lower, based onthese assumptions, your expenses would be:

Class K Institutional Class1 Year $59 $653 Years $186 $2055 Years $324 $35710 Years $726 $798

Portfolio TurnoverThe Fund pays transaction costs, such as commissions, when itbuys and sells securities (or “turns over” its portfolio). A higherportfolio turnover rate may indicate higher transaction costs andmay result in higher taxes when Fund shares are held in ataxable account. These transaction costs, which are not reflectedin “Annual Fund Operating Expenses” or in the “Example ofExpenses” above, affect the Fund’s performance. During theFund’s most recent fiscal year, the Fund’s portfolio turnover ratewas 26% of the average value of its portfolio.

Principal Investment StrategiesThe Fund seeks to meet its objective by investing in a diversified,international portfolio of common stocks and other equitysecurities of issuers located in countries of developed andemerging markets.

The Fund invests predominantly in securities issued bycompanies located in countries outside the U.S., including arange of developed and emerging market countries. The Fundmay, however, invest up to 10% of its net assets in commonstocks and other equities of companies located in the U.S. Undernormal circumstances, the Fund invests in securities of issuerslocated in at least three countries outside the U.S. and typicallymaintains substantial exposure to emerging markets. The Fundinvests in equity securities either directly or indirectly, such asthrough depositary receipts, and may invest in preferred stocks,convertible securities and warrants. The Fund is not constrainedwith respect to market capitalization and may participate in initialpublic offerings (“IPOs”) and in securities offerings that are notregistered in the U.S. In selecting companies for investment, theportfolio managers generally consider issuers in both developedand emerging markets.

The portfolio managers employ a bottom-up approach to stockselection and select companies without being constrained by abenchmark. The portfolio managers focus on company researchand the long-term outlook of companies and industries. Ideascan come from a wide variety of sources, including, but notlimited to, research trips, company meetings, and relationshipswith industry thought leaders and academic institutions. Stockideas are normally researched to assess a range of factors,including: long-term growth potential, geographic and industrypositioning, competitive advantage, management, financialstrength and valuation. The intended outcome is a diversifiedportfolio of between 50 and 60 growth companies with thepotential to outperform the benchmark over the long term. Theprocess can result in significant exposure to a single country or asmall number of countries, which in recent periods have includedJapan and China. The Fund expects to have considerableexposure to Chinese companies, including through China Ashares, which are common stocks and other equity securities thatare listed or traded on a Chinese stock exchange and which arequoted in renminbi. The Fund aims to hold securities for longperiods (typically 5 years), which results in relatively low portfolioturnover and is in line with the Fund’s long-term investmentoutlook. Because the Fund aims to hold securities for longperiods, the Fund does not expect to actively reduce its holdingsof shares of particular issuers (other than in response topurchase and redemption requests) even if market movementscause the Fund to operate as a non-diversified company for anextended period of time.

The Fund may invest without limitation in securities quoted ordenominated in currencies other than the U.S. dollar and mayhold such currencies. The Fund does not expect to engage incurrency hedging and thus expects to be fully exposed tocurrency fluctuations relative to the U.S. dollar.

Principal RisksThe Fund’s net asset value and returns will be impacted by theperformance of the underlying investments of the Fund. Aninvestment in the Fund is not a deposit in a bank and is not

Baillie Gifford Funds – Prospectus

insured or guaranteed by the Federal Deposit InsuranceCorporation or any other government agency. You could losemoney by investing in the Fund.

The principal risks of investing in the Fund (in alphabetical orderafter the first four risks) are:

— Investment Style Risk – Baillie Gifford Overseas Limited(the “Manager”) actively makes investment decisions for theFund through bottom-up stock selection. Accordingly, theFund will have risk characteristics that differ from itsbenchmark index. The Manager’s judgments about theattractiveness, relative value, or potential appreciation of aparticular stock may prove to be incorrect and cause theFund to lose money or underperform compared to itsbenchmark index. There can be no assurance that theManager’s investment decisions will produce the desiredresults.

— Growth Stock Risk – The prices of growth stocks may bebased largely on expectations of future earnings, and theirprices can decline rapidly and significantly in reaction tonegative news. Growth stocks may underperform stocks inother broad style categories (and the stock market as awhole) over any period of time and may shift in and out offavor with investors generally, sometimes rapidly, dependingon changes in market, economic, and other factors.

— Long-Term Investment Strategy Risk – The Fund pursues along-term investment approach, typically seeking returnsover a period of several years. This investment style maycause the Fund to lose money or underperform compared toits benchmark index or other mutual funds over extendedperiods of time, and the Fund may not perform as expectedin the long term. An investment in the Fund may be moresuitable for long-term investors who can bear the risk ofshort- or medium-term fluctuations in the value of the Fund’sportfolio.

— Non-U.S. Investment Risk – Non-U.S. securities are subjectto additional risks, including less liquidity, increased volatility,less transparency, withholding or other taxes, increasedvulnerability to adverse changes in local and globaleconomic conditions, less regulation, and possiblefluctuation in value due to adverse political conditions.Foreign portfolio transactions generally involve highercommission rates, transfer taxes, and custodial costs thansimilar transactions in the U.S.

— Asia Risk – Investing in securities of companies located in orwith exposure to Asian countries involves certain risks andconsiderations not typically associated with investing insecurities of U.S. issuers, including different financialreporting standards, currency exchange rate fluctuations,and highly regulated markets with the potential forgovernment interference. The economies of many Asiancountries are heavily dependent on international trade andon only a few industries or commodities and, as a result, canbe adversely affected by trade barriers, exchange controlsand other measures imposed or negotiated by the countrieswith which they trade. Some Asian securities may be lessliquid than U.S. or other foreign securities. See “China Risk”and “Japan Risk” for additional details regarding the risks ofinvesting in those countries.

Additionally, many of the economies of countries in Asia areconsidered emerging market or frontier market economies.These Asian economies are often characterized by highinflation, undeveloped financial service sectors, frequentcurrency fluctuations, devaluations, or restrictions, politicaland social instability, and less efficient markets. See“Emerging Markets Risk” for additional details regarding therisks of investing in such countries.

— China Risk – Investing in securities of Chinese issuersinvolves certain risks and considerations not typicallyassociated with investing in securities of U.S. issuers,including, among others, more frequent trading suspensionsand government interventions (including by nationalization ofassets), currency exchange rate fluctuations or blockages,limits on the use of brokers and on foreign ownership,different financial reporting standards, higher dependence onexports and international trade, potential for increased tradetariffs, sanctions, embargoes and other trade limitations, andcustody risks. U.S. sanctions or other investment restrictionscould preclude the Fund from investing in certain Chineseissuers or cause the Fund to sell investments at adisadvantageous time. Significant portions of the Chinesesecurities markets may become rapidly illiquid, as Chineseissuers have the ability to suspend the trading of their equitysecurities, and have shown a willingness to exercise thatoption in response to market volatility and other events.

— Conflicts of Interest Risk – The Manager’s relationships withthe Fund’s institutional investor base may give rise to variousconflicts of interest, since the Manager will sometimes havean incentive to favor those shareholders over othershareholders in the Fund. In addition, the Manager serves asinvestment adviser to various clients other than the Fund,some of whom may pursue strategies that are substantiallysimilar or nearly identical to investment strategies pursuedby the Fund. This “side-by-side” management may give riseto various conflicts of interest, including, for example, inconnection with the fair allocation of trades among theManager’s clients or the sharing of different, more, or moretimely information regarding investment performance,portfolio holdings, strategy developments and/or theManager’s general market outlook. Furthermore, ifinvestment personnel of the Manager hold board or otherpositions at outside companies, they could be exposed tomaterial non-public information potentially impeding ordelaying a Fund’s ability to buy or sell certain investments, orthey could otherwise be restricted in their ability toparticipate in a Fund’s investment process.

— Currency Risk – The Fund may realize a loss if it hasexposure to a non-U.S. currency, and this non-U.S. currencydeclines in value, relative to the U.S. dollar. The Fund doesnot expect to engage in currency hedging and thus expectsto be fully exposed to currency fluctuations relative to theU.S. dollar.

— Emerging Markets Risk – To the extent the Fund invests inemerging market securities, the Fund may be exposed togreater market, credit, currency, liquidity, legal, political,technical and other risks different from, or greater than, therisks of investing in developed markets.

Baillie Gifford Funds – Prospectus

— Equity Securities Risk – Equity securities may react morestrongly to changes in an issuer’s financial condition orprospects than other securities of the same issuer. Investingin equity securities indirectly, such as through participatorynotes or depositary receipts, may involve other risks such asthe risk that the counterparty may default or that theinvestment does not track the underlying security asexpected.

— Focused Investment Risk – Should the Fund focus itsinvestments in related, or a limited number of, countries,regions, sectors, or companies, this would create more riskand greater volatility than if the Fund’s investments wereless focused.

— Geographic Focus Risk – The Fund expects to focus itsinvestments in a limited number of countries or geographicregions, and as a result may not offer the same level ofdiversification of risks as a more broadly global fund becausethe Fund will be exposed to a smaller geographic area. Theperformance of a fund that is less diversified across countriesor geographic regions will be closely tied to market, currency,economic, political, environmental, or regulatory conditionsand developments in the countries or regions in which thefund invests, and may be more volatile than the performanceof a more geographically-diversified portfolio.

— Government and Regulatory Risk – Governmental andregulatory authorities in the United States and othercountries, have taken, and may in the future take, actionsintervening in the markets in which the Fund invests and inthe economy more generally. Governmental and regulatoryauthorities may also act to increase the scope or burden ofregulations applicable to the Fund or to the companies inwhich the Fund invests. The effects of these actions on themarkets generally, and Fund’s investment program inparticular, can be uncertain and could restrict the ability ofthe Fund to fully implement its investment strategies, eithergenerally, or with respect to certain securities, industries, orcountries. By contrast, markets in some non-U.S. countrieshistorically have been subject to little regulation or oversightby governmental or regulatory authorities, which couldheighten the risk of loss due to fraud or market failures inthose countries. Governments, agencies, or other regulatorybodies in any country may adopt or change laws orregulations that could adversely affect the Fund or themarket value of an instrument held by the Fund.

— Information Technology Risk – Cyber-attacks, disruptions, orfailures that affect the Fund’s service providers, counterparties,the securities markets generally, other market participants, orissuers of securities held by the Fund may adversely affect theFund and its shareholders, including by causing losses for theFund or impairing Fund operations.

— IPO Risk – The Fund may purchase securities in IPOs.These securities are subject to many of the same risks ofinvesting in companies with smaller market capitalizations.Securities issued in IPOs have no trading history, andinformation about the companies may be available for verylimited periods. In addition, the prices of securities sold inIPOs may be highly volatile.

— Japan Risk – The Japanese economy has only recentlyemerged from a prolonged economic downturn. Since the

year 2000, Japan’s economic growth rate has remainedrelatively low, and it may remain low in the future. Japan’seconomy is characterized by an aging demographic,declining population, large government debt, and a highlyregulated labor market. In the longer term, Japan will have toaddress the effects of an aging population, including theimpact of a shrinking work force and higher welfare costs.Japan’s economic recovery has been affected by economicdistress resulting from a number of natural disasters,including disasters that caused damage to nuclear powerplants in the region. Such environmental catastrophes havecaused Japan’s financial markets to fluctuate dramatically.Japan continues to be subject to the risk of natural disasters,such as earthquakes, volcanic eruptions, typhoons andtsunamis, which could negatively affect the Japaneseeconomy.

— Large-Capitalization Securities Risk – Returns oninvestments in securities of large companies could trail thereturns on investments in securities of smaller and medium-sized companies. Larger companies may be unable torespond as quickly as smaller and medium-sized companiesto competitive challenges or to changes in business, product,financial, or other market conditions. Larger companies maynot be able to achieve or maintain growth at the high ratesthat may be achieved by well-managed smaller and medium-sized companies.

— Liquidity Risk – The Fund’s investments may be subject tolow trading volume, lack of a market maker, contractual lock-in periods or regulatory restrictions, and the Fund may holdlarge positions in particular securities. As a result, it may notbe possible to sell an investment at a particular time or at anacceptable price. Liquidity risk may be magnified duringperiods of changing interest rates, significant shareholderredemptions or market turmoil. Illiquid securities may tradeat a discount from comparable, more liquid investments andmay be subject to wide fluctuations in market value. In somecases, due to unanticipated levels of illiquidity the Fund mayseek to meet its redemption obligations wholly or in part bydistributions of assets in-kind.

— Market Disruption and Geopolitical Risk – The value of theFund’s investments could be adversely affected by eventsthat disrupt securities markets and adversely affect globalmarkets such as war, terrorism, public health crises, andgeopolitical events and by changes in non-U.S. and U.S.economic and political conditions. As a result of theseevents, the Fund could lose money, experience significantredemptions, encounter operational difficulties, and sufferother negative impacts.

— Market Risk – The value of the Fund’s investments will beaffected by fluctuations in the stock markets in which theFund is invested, factors affecting a particular industry orindustries, real or perceived adverse economic conditions,changes in interest or currency rates or adverse investorsentiment generally. Declines in securities market prices mayreduce the net asset value of the Fund’s shares.

— Service Provider Risk – The Fund will be affected by theManager’s investment techniques, analyses, assessmentsand employee retention. Similarly, adverse events orperformance failures at a service provider, such as human

error, inadequate controls or insolvency, have the ability toadversely affect the Fund.

— Settlement Risk – The Fund may experience delays insettlement due to the different clearance and settlementprocedures in non-U.S. countries. Such delays may increasecredit risk to the Fund, limit the ability of the Fund to reinvestthe proceeds of a sale of securities, or prevent the Fundfrom selling securities at times and prices it considersdesirable.

— Small- and Medium-Capitalization Securities Risk – Securitiesof small- and medium-capitalization companies can be morevolatile due to various factors including more limited productlines, financial and management resources and marketdistribution channels, as well as shorter operating historiesand potentially reduced liquidity, especially during marketdeclines, than the securities of larger, more establishedcompanies.

— Valuation Risk – In certain circumstances, some of theFund’s portfolio holdings may be valued on the basis offactors other than market quotations by employing the fairvalue procedures adopted by the Board of Trustees of theTrust (the “Board”). This may occur more often in times ofmarket turmoil or reduced liquidity. Portfolio holdings that arevalued using techniques other than market quotations,including “fair valued” securities, may be subject to greaterfluctuation in their valuations from one day to the next than ifmarket quotations were used. There is no assurance that theFund could sell or close out a portfolio position for the valueestablished for it at any time, and it is possible that the Fundwould incur a loss because a portfolio position is sold orclosed out at a discount to the valuation established by theFund at that time.

PerformanceThe bar chart and table below provide some indication of therisks of investing in the Fund by showing changes in the Fund’sannual total returns from year to year and by comparing theFund’s average annual total returns with those of the Fund’sbenchmarks. Past performance (before and after taxes) is not anindication of future performance.

Baillie Gifford International Smaller Companies Fund

Investment ObjectiveBaillie Gifford International Smaller Companies Fund seekscapital appreciation.

Fees and ExpensesThe tables below describe the fees and expenses that you maypay if you buy, hold, and sell shares of the Fund. You may payother fees, such as brokerage commissions and other fees tofinancial intermediaries, which are not reflected in the tables andexamples below.

Shareholder Fees(Fees paid directly from your investment)

Class K Institutional ClassNone None

Annual Fund Operating Expenses(Expenses that you pay each year as a percentage of the valueof your investment)

Class K Institutional ClassManagement Fees(a) 0.75% 0.75%Distribution (12b-1) Fees None NoneOther Expenses(b) 16.45% 16.45%Total Annual Fund Operating Expenses 17.20% 17.20%Fee Waiver and/or Expense Reimbursement(c) (16.30)% (16.30)%Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement(c) 0.90% 0.90%

(a) The Management Fee consists of an Advisory Fee and anAdministration and Supervisory Fee paid by the Fund to BaillieGifford Overseas Limited.

(b) While Other Expenses for the last fiscal year were the same forInstitutional Class and Class K, Other Expenses for InstitutionalClass are expected to be higher than those of Class K in the future,since Institutional Class is expected to bear sub-accountingexpenses.

(c) Baillie Gifford Overseas Limited has contractually agreed to waiveits fees and/or bear Other Expenses of the Fund until April 30, 2022to the extent that the Fund’s Total Annual Fund OperatingExpenses (excluding taxes, sub-accounting expenses andextraordinary expenses) exceed 0.90% for Class K and InstitutionalClass shares. This contractual agreement may only be terminatedby the Board of Trustees of the Trust. Because this cap of 0.90%excludes sub-accounting expenses, Total Annual Fund OperatingExpenses After Fee Waiver and or Expense Reimbursement forInstitutional Class are expected to exceed the cap in the future.

Example of ExpensesThe example below is intended to help you compare the cost ofinvesting in the Fund with the cost of investing in other mutualfunds. It assumes that you invest $10,000 in the Fund for the timeperiods indicated, regardless of whether or not you redeem yourshares at the end of such periods. It also assumes that yourinvestment has a 5% return each year and that the Fund’soperating expenses remain the same. The example below alsoapplies any contractual expense waivers and/or expensereimbursements to the first year of each period listed in the table.

Although your actual costs may be higher or lower, based onthese assumptions, your expenses would be:

Class K Institutional Class1 Year $92 $923 Years $3,249 $3,2495 Years $5,683 $5,68310 Years $9,600 $9,600

Portfolio TurnoverThe Fund pays transaction costs, such as commissions, when itbuys and sells securities (or “turns over” its portfolio). A higherportfolio turnover rate may indicate higher transaction costs andmay result in higher taxes when Fund shares are held in ataxable account. These transaction costs, which are not reflectedin “Annual Fund Operating Expenses” or in the “Example ofExpenses” above, affect the Fund’s performance. During theFund’s most recent fiscal year, the Fund’s portfolio turnover ratewas 16% of the average value of its portfolio.

Principal Investment StrategiesThe Fund seeks to meet its objective by investing in aninternational portfolio of common stocks of smaller companieslocated in countries of developed and emerging markets.

When selecting companies for initial inclusion in the Fund’sportfolio, the Fund seeks to invest in companies with a marketcapitalization in the region of $2 billion or lower. The Fund maycontinue to hold, and may increase its investment in, portfoliocompanies whose market capitalization subsequently increases.The Fund typically will not seek to increase the percentage of itsportfolio invested in any company whose market capitalization isin excess of $5 billion. However, in cases where the marketcapitalization of a portfolio company has increased above$5 billion, the Fund may continue to purchase additional sharesof that company so long as the percentage of the Fund’sportfolio represented by that company will be the same as orlower than it was before the company’s market capitalizationincreased above $5 billion. The Fund expects over time to have asubstantial portion of its portfolio invested in companies with amarket capitalization in excess of $2 billion. However, undernormal circumstances, the Fund invests at least 80% of its netassets (plus any borrowings for investment purposes) insecurities of smaller companies. The Manager currently definesa “smaller company” as a company with a market capitalizationthat does not exceed $10 billion.

In addition, under normal circumstances, the Fund will investprimarily in companies located outside the U.S. The Fundordinarily invests in securities of issuers located in at least threecountries outside the U.S., although the Fund may focus itsinvestments in a small number of countries or regions. The Fundinvests in equity securities either directly or indirectly, such asthrough depositary receipts, and may invest in preferred stocks,convertible securities and warrants. The Fund may participate ininitial public offerings (“IPOs”) and in securities offerings that arenot registered in the U.S. In some emerging markets, the Fundmay invest in companies that qualify as smaller companies butstill are among the largest in that market.

Baillie Gifford Funds – Prospectus

The portfolio managers employ a bottom-up approach to stockselection and principally select companies without beingconstrained by the Fund’s benchmark, the MSCI ACWI ex-USASmall Cap Index. The portfolio managers focus on companyresearch and the long-term outlook of companies. Ideas cancome from a wide variety of sources, including, but not limited to,research trips, company meetings, and relationships with industrythought leaders and academic institutions. Stock ideas arenormally researched to assess a range of factors, including:long-term growth potential, geographic and industry positioning,competitive advantage, management, financial strength andvaluation. The intended outcome is a diversified portfolio ofbetween 75 and 175 growth companies with the potential tooutperform the benchmark over the long term. The process canresult in significant exposure to a single country or a smallnumber of countries, which in recent periods has included Japan.The Fund aims to hold securities for long periods (typically5 years), which results in relatively low portfolio turnover and is inline with the Fund’s long-term investment outlook.

The Fund may invest without limitation in securities quoted ordenominated in currencies other than the U.S. dollar and mayhold such currencies. The Fund does not expect to engage incurrency hedging and thus expects to be fully exposed tocurrency fluctuations relative to the U.S. dollar.

Principal RisksThe Fund’s net asset value and returns will be impacted by theperformance of the underlying investments of the Fund. Aninvestment in the Fund is not a deposit in a bank and is notinsured or guaranteed by the Federal Deposit InsuranceCorporation or any other government agency. You could losemoney by investing in the Fund.

The principal risks of investing in the Fund (in alphabetical orderafter the first six risks) are:

— Investment Style Risk – Baillie Gifford Overseas Limited(the “Manager”) actively makes investment decisions for theFund through bottom-up stock selection. Accordingly, theFund will have risk characteristics that differ from itsbenchmark index. The Manager’s judgments about theattractiveness, relative value, or potential appreciation of aparticular stock may prove to be incorrect and cause theFund to lose money or underperform compared to itsbenchmark index. There can be no assurance that theManager’s investment decisions will produce the desiredresults.

— Growth Stock Risk – The prices of growth stocks may bebased largely on expectations of future earnings, and theirprices can decline rapidly and significantly in reaction tonegative news. Growth stocks may underperform stocks inother broad style categories (and the stock market as awhole) over any period of time and may shift in and out offavor with investors generally, sometimes rapidly, dependingon changes in market, economic, and other factors.

— Long-Term Investment Strategy Risk – The Fund pursues along-term investment approach, typically seeking returnsover a period of several years. This investment style maycause the Fund to lose money or underperform compared toits benchmark index or other mutual funds over extended

periods of time, and the Fund may not perform as expectedin the long term. An investment in the Fund may be moresuitable for long-term investors who can bear the risk ofshort- or medium-term fluctuations in the value of the Fund’sportfolio.

— Asia Risk – Investing in securities of companies located in orwith exposure to Asian countries involves certain risks andconsiderations not typically associated with investing insecurities of U.S. issuers, including different financialreporting standards, currency exchange rate fluctuations,and highly regulated markets with the potential forgovernment interference. The economies of many Asiancountries are heavily dependent on international trade andon only a few industries or commodities and, as a result, canbe adversely affected by trade barriers, exchange controlsand other measures imposed or negotiated by the countrieswith which they trade. Some Asian securities may be lessliquid than U.S. or other foreign securities. See “Japan Risk”for additional details regarding the risks of investing in thatcountry.

Additionally, many of the economies of countries in Asia areconsidered emerging market or frontier market economies.These Asian economies are often characterized by highinflation, undeveloped financial service sectors, frequentcurrency fluctuations, devaluations, or restrictions, politicaland social instability, and less efficient markets. See“Emerging Markets Risk” for additional details regarding therisks of investing in such countries.

— Small- and Medium-Capitalization Securities Risk – Securitiesof small- and medium-capitalization companies can be morevolatile due to various factors including more limited productlines, financial and management resources and marketdistribution channels, as well as shorter operating historiesand potentially reduced liquidity, especially during marketdeclines, than the securities of larger, more establishedcompanies.

— Non-U.S. Investment Risk – Non-U.S. securities are subjectto additional risks, including less liquidity, increased volatility,less transparency, withholding or other taxes, increasedvulnerability to adverse changes in local and globaleconomic conditions, less regulation, and possiblefluctuation in value due to adverse political conditions.Foreign portfolio transactions generally involve highercommission rates, transfer taxes, and custodial costs thansimilar transactions in the U.S.

— Conflicts of Interest Risk – The Manager’s relationships withthe Fund’s institutional investor base may give rise to variousconflicts of interest, since the Manager will sometimes havean incentive to favor those shareholders over othershareholders in the Fund. In addition, the Manager serves asinvestment adviser to various clients other than the Fund,some of whom may pursue strategies that are substantiallysimilar or nearly identical to investment strategies pursuedby the Fund. This “side-by-side” management may give riseto various conflicts of interest, including, for example, inconnection with the fair allocation of trades among theManager’s clients or the sharing of different, more, or moretimely information regarding investment performance,

portfolio holdings, strategy developments and/or theManager’s general market outlook. Furthermore, ifinvestment personnel of the Manager hold board or otherpositions at outside companies, they could be exposed tomaterial non-public information potentially impeding ordelaying a Fund’s ability to buy or sell certain investments, orthey could otherwise be restricted in their ability toparticipate in a Fund’s investment process.

— Currency Risk – The Fund may realize a loss if it hasexposure to a non-U.S. currency, and this non-U.S. currencydeclines in value, relative to the U.S. dollar. The Fund doesnot expect to engage in currency hedging and thus expectsto be fully exposed to currency fluctuations relative to theU.S. dollar.

— Emerging Markets Risk – To the extent the Fund invests inemerging market securities, the Fund may be exposed togreater market, credit, currency, liquidity, legal, political,technical and other risks different from, or greater than, therisks of investing in developed markets.

— Equity Securities Risk – Equity securities may react morestrongly to changes in an issuer’s financial condition orprospects than other securities of the same issuer. Investingin equity securities indirectly, such as through participatorynotes or depositary receipts, may involve other risks such asthe risk that the counterparty may default or that theinvestment does not track the underlying security asexpected.

— Focused Investment Risk – Should the Fund focus itsinvestments in related, or a limited number of, countries,regions, sectors, or companies, this would create more riskand greater volatility than if the Fund’s investments wereless focused.

— Geographic Focus Risk – The Fund expects to focus itsinvestments in a limited number of countries or geographicregions, and as a result may not offer the same level ofdiversification of risks as a more broadly global fundbecause the Fund will be exposed to a smaller geographicarea. The performance of a fund that is less diversifiedacross countries or geographic regions will be closely tied tomarket, currency, economic, political, environmental, orregulatory conditions and developments in the countries orregions in which the fund invests, and may be more volatilethan the performance of a more geographically-diversifiedportfolio.

— Government and Regulatory Risk – Governmental andregulatory authorities in the United States and othercountries, have taken, and may in the future take, actionsintervening in the markets in which the Fund invests and inthe economy more generally. Governmental and regulatoryauthorities may also act to increase the scope or burden ofregulations applicable to the Fund or to the companies inwhich the Fund invests. The effects of these actions on themarkets generally, and Fund’s investment program inparticular, can be uncertain and could restrict the ability ofthe Fund to fully implement its investment strategies, eithergenerally, or with respect to certain securities, industries, orcountries. By contrast, markets in some non-U.S. countrieshistorically have been subject to little regulation or oversight

by governmental or regulatory authorities, which couldheighten the risk of loss due to fraud or market failures inthose countries. Governments, agencies, or other regulatorybodies in any country may adopt or change laws orregulations that could adversely affect the Fund or themarket value of an instrument held by the Fund.

— Information Technology Risk – Cyber-attacks, disruptions, orfailures that affect the Fund’s service providers, counterparties,the securities markets generally, other market participants, orissuers of securities held by the Fund may adversely affect theFund and its shareholders, including by causing losses for theFund or impairing Fund operations.

— IPO Risk – The Fund may purchase securities in IPOs.These securities are subject to many of the same risks ofinvesting in companies with smaller market capitalizations.Securities issued in IPOs have no trading history, andinformation about the companies may be available for verylimited periods. In addition, the prices of securities sold inIPOs may be highly volatile.

— Japan Risk – The Japanese economy has only recentlyemerged from a prolonged economic downturn. Since theyear 2000, Japan’s economic growth rate has remainedrelatively low, and it may remain low in the future. Japan’seconomy is characterized by an aging demographic,declining population, large government debt, and a highlyregulated labor market. In the longer term, Japan will have toaddress the effects of an aging population, including theimpact of a shrinking work force and higher welfare costs.Japan’s economic recovery has been affected by economicdistress resulting from a number of natural disasters,including disasters that caused damage to nuclear powerplants in the region. Such environmental catastrophes havecaused Japan’s financial markets to fluctuate dramatically.Japan continues to be subject to the risk of natural disasters,such as earthquakes, volcanic eruptions, typhoons andtsunamis, which could negatively affect the Japaneseeconomy.

— Liquidity Risk – The Fund’s investments may be subject tolow trading volume, lack of a market maker, contractual lock-in periods or regulatory restrictions, and the Fund may holdlarge positions in particular securities. As a result, it may notbe possible to sell an investment at a particular time or at anacceptable price. Liquidity risk may be magnified duringperiods of changing interest rates, significant shareholderredemptions or market turmoil. Illiquid securities may tradeat a discount from comparable, more liquid investments andmay be subject to wide fluctuations in market value. In somecases, due to unanticipated levels of illiquidity the Fund mayseek to meet its redemption obligations wholly or in part bydistributions of assets in-kind.

— Market Disruption and Geopolitical Risk – The value of theFund’s investments could be adversely affected by eventsthat disrupt securities markets and adversely affect globalmarkets such as war, terrorism, public health crises, andgeopolitical events and by changes in non-U.S. and U.S.economic and political conditions. As a result of theseevents, the Fund could lose money, experience significant

redemptions, encounter operational difficulties, and sufferother negative impacts.

— Market Risk – The value of the Fund’s investments will beaffected by fluctuations in the stock markets in which theFund is invested, factors affecting a particular industry orindustries, real or perceived adverse economic conditions,changes in interest or currency rates or adverse investorsentiment generally. Declines in securities market prices mayreduce the net asset value of the Fund’s shares.

— New and Smaller-Sized Funds Risk – New funds andsmaller-sized funds will be subject to greater liquidity riskdue to their smaller asset bases and may be required to sellsecurities at disadvantageous times or prices due to a largeshareholder redemption. A fund that has been recentlyformed will have limited or no performance history forinvestors to evaluate and may not reach or maintain asufficient asset size to effectively implement its investmentstrategy.

— Service Provider Risk – The Fund will be affected by theManager’s investment techniques, analyses, assessmentsand employee retention. Similarly, adverse events orperformance failures at a service provider, such as humanerror, inadequate controls or insolvency, have the ability toadversely affect the Fund.

— Settlement Risk – The Fund may experience delays insettlement due to the different clearance and settlementprocedures in non-U.S. countries. Such delays may increasecredit risk to the Fund, limit the ability of the Fund to reinvestthe proceeds of a sale of securities, or prevent the Fundfrom selling securities at times and prices it considersdesirable.

— Valuation Risk – In certain circumstances, some of theFund’s portfolio holdings may be valued on the basis offactors other than market quotations by employing the fairvalue procedures adopted by the Board of Trustees of theTrust (the “Board”). This may occur more often in times ofmarket turmoil or reduced liquidity. Portfolio holdings that arevalued using techniques other than market quotations,including “fair valued” securities, may be subject to greaterfluctuation in their valuations from one day to the next than ifmarket quotations were used. There is no assurance that theFund could sell or close out a portfolio position for the valueestablished for it at any time, and it is possible that the Fundwould incur a loss because a portfolio position is sold orclosed out at a discount to the valuation established by theFund at that time.

PerformanceThe bar chart and table below provide some indication of therisks of investing in the Fund by showing changes in the Fund’sannual total returns from year to year and by comparing theFund’s average annual total returns with those of the Fund’sbenchmark. Past performance (before and after taxes) is not anindication of future performance.

Baillie Gifford Japan Growth Fund

Investment ObjectiveBaillie Gifford Japan Growth Fund seeks capital appreciation.

Fees and ExpensesThe tables below describe the fees and expenses that you maypay if you buy, hold, and sell shares of the Fund. You may payother fees, such as brokerage commissions and other fees tofinancial intermediaries, which are not reflected in the tables andexamples below.

Shareholder Fees(Fees paid directly from your investment)

Class K Institutional ClassNone None

Annual Fund Operating Expenses(Expenses that you pay each year as a percentage of the valueof your investment)

Class K Institutional ClassManagement Fees(a) 0.60% 0.60%Distribution (12b-1) Fees None NoneOther Expenses(b) 16.90% 17.05%Total Annual Fund Operating Expenses 17.50% 17.65%Fee Waiver and/or Expense Reimbursement(c) (16.75)% (16.75)%Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement(c) 0.75% 0.90%

(a) The Management Fee consists of an Advisory Fee and anAdministration and Supervisory Fee paid by the Fund to BaillieGifford Overseas Limited.

(b) Class K and Institutional Class were unfunded as of December 31,2020. Therefore Other Expenses have been estimated for thecurrent fiscal year assuming Fund assets of $1 million.

(c) Baillie Gifford Overseas Limited has contractually agreed to waiveits fees and/or bear Other Expenses of the Fund until April 30, 2022to the extent that the Fund’s Total Annual Fund OperatingExpenses (excluding taxes, sub-accounting expenses andextraordinary expenses) exceed 0.75% for Class K and InstitutionalClass shares. This contractual agreement may only be terminatedby the Board of Trustees of the Trust. Expenses afterwaiver/reimbursement exceed 0.75% for Institutional Class due toestimated sub-accounting expenses of 0.15%.

Example of ExpensesThe example below is intended to help you compare the cost ofinvesting in the Fund with the cost of investing in other mutualfunds. It assumes that you invest $10,000 in the Fund for the timeperiods indicated, regardless of whether or not you redeem yourshares at the end of such periods. It also assumes that yourinvestment has a 5% return each year and that the Fund’soperating expenses remain the same. The example below alsoapplies any contractual expense waivers and/or expensereimbursements to the first year of each period listed in the table.

Although your actual costs may be higher or lower, based onthese assumptions, your expenses would be:

Class K Institutional Class1 Year $77 $923 Years $3,284 $3,316

Portfolio TurnoverThe Fund pays transaction costs, such as commissions, when itbuys and sells securities (or “turns over” its portfolio). A higherportfolio turnover rate may indicate higher transaction costs andmay result in higher taxes when Fund shares are held in ataxable account. These transaction costs, which are not reflectedin “Annual Fund Operating Expenses” or in the “Example ofExpenses” above, affect the Fund’s performance. Because theFund has not commenced operations, it does not have a portfolioturnover rate.

Principal Investment StrategiesThe Fund will seek to meet its objective by investing in a portfolioof common stocks and other equity securities of issuers locatedin Japan. Under normal circumstances, the Fund will invest atleast 80% of its net assets (plus any borrowings for investmentpurposes) in equity securities of companies located in Japan.The Fund will invest in equity securities either directly orindirectly, such as through depositary receipts, and may invest inpreferred stocks, convertible securities and warrants. The Fund isnot constrained with respect to market capitalization and mayparticipate in initial public offerings (“IPOs”) and in securitiesofferings that are not registered in the U.S.

The portfolio managers employ a bottom-up approach to stockselection and will principally select companies without beingconstrained by the Tokyo Stock Price Index (“TOPIX”), theFund’s underlying benchmark. The portfolio managers focus oncompany research and the long-term outlook of companies andindustries. Ideas can come from a wide variety of sources,including, but not limited to, research trips, company meetings,and relationships with industry thought leaders and academicinstitutions. Stock ideas are normally researched to assess arange of factors, including: long-term growth potential,geographic and industry positioning, competitive advantage,management, financial strength and valuation. The intendedoutcome is a diversified portfolio of between 35 and 55 growthcompanies with the potential to outperform the benchmark overthe long-term. The Fund aims to hold securities for long periods(typically 5 years), which is expected to result in relatively lowportfolio turnover and be in line with the Fund’s long-terminvestment outlook.

The Fund may invest without limitation in securities quoted ordenominated in currencies other than the U.S. dollar and mayhold such currencies. The Fund does not expect to engage incurrency hedging and thus expects to be fully exposed tocurrency fluctuations relative to the U.S. dollar.

Corporation or any other government agency. You could losemoney by investing in the Fund.

The principal risks of investing in the Fund (in alphabetical orderafter the first five risks) are:

— Japan Risk – The Japanese economy has only recentlyemerged from a prolonged economic downturn. Since theyear 2000, Japan’s economic growth rate has remainedrelatively low, and it may remain low in the future. Japan’seconomy is characterized by an aging demographic,declining population, large government debt, and a highlyregulated labor market. In the longer term, Japan will have toaddress the effects of an aging population, including theimpact of a shrinking work force and higher welfare costs.Japan’s economic recovery has been affected by economicdistress resulting from a number of natural disasters,including disasters that caused damage to nuclear powerplants in the region. Such environmental catastrophes havecaused Japan’s financial markets to fluctuate dramatically.Japan continues to be subject to the risk of natural disasters,such as earthquakes, volcanic eruptions, typhoons andtsunamis, which could negatively affect the Japaneseeconomy.

— Investment Style Risk – Baillie Gifford Overseas Limited(the “Manager”) actively makes investment decisions for theFund through bottom-up stock selection. Accordingly, theFund will have risk characteristics that differ from itsbenchmark index. The Manager’s judgments about theattractiveness, relative value, or potential appreciation of aparticular stock may prove to be incorrect and cause theFund to lose money or underperform compared to itsbenchmark index. There can be no assurance that theManager’s investment decisions will produce the desiredresults.

— Growth Stock Risk – The prices of growth stocks may bebased largely on expectations of future earnings, and theirprices can decline rapidly and significantly in reaction tonegative news. Growth stocks may underperform stocks inother broad style categories (and the stock market as awhole) over any period of time and may shift in and out offavor with investors generally, sometimes rapidly, dependingon changes in market, economic, and other factors.

— Long-Term Investment Strategy Risk – The Fund pursues along-term investment approach, typically seeking returnsover a period of several years. This investment style maycause the Fund to lose money or underperform compared toits benchmark index or other mutual funds over extendedperiods of time, and the Fund may not perform as expectedin the long term. An investment in the Fund may be moresuitable for long-term investors who can bear the risk ofshort- or medium-term fluctuations in the value of the Fund’sportfolio.

— Geographic Focus Risk – The Fund expects to focus itsinvestments in a limited number of countries or geographicregions, and as a result may not offer the same level ofdiversification of risks as a more broadly global fundbecause the Fund will be exposed to a smaller geographicarea. The performance of a fund that is less diversifiedacross countries or geographic regions will be closely tied to

market, currency, economic, political, environmental, orregulatory conditions and developments in the countries orregions in which the fund invests, and may be more volatilethan the performance of a more geographically-diversifiedportfolio.

— Conflicts of Interest Risk – The Manager’s relationships withthe Fund’s institutional investor base may give rise to variousconflicts of interest, since the Manager will sometimes havean incentive to favor those shareholders over othershareholders in the Fund. In addition, the Manager serves asinvestment adviser to various clients other than the Fund,some of whom may pursue strategies that are substantiallysimilar or nearly identical to investment strategies pursuedby the Fund. This “side-by-side” management may give riseto various conflicts of interest, including, for example, inconnection with the fair allocation of trades among theManager’s clients or the sharing of different, more, or moretimely information regarding investment performance,portfolio holdings, strategy developments and/or theManager’s general market outlook. Furthermore, ifinvestment personnel of the Manager hold board or otherpositions at outside companies, they could be exposed tomaterial non-public information potentially impeding ordelaying a Fund’s ability to buy or sell certain investments, orthey could otherwise be restricted in their ability toparticipate in a Fund’s investment process.

— Currency Risk – The Fund may realize a loss if it hasexposure to a non-U.S. currency, and this non-U.S. currencydeclines in value, relative to the U.S. dollar. The Fund doesnot expect to engage in currency hedging and thus expectsto be fully exposed to currency fluctuations relative to theU.S. dollar.

— Equity Securities Risk – Equity securities may react morestrongly to changes in an issuer’s financial condition orprospects than other securities of the same issuer. Investingin equity securities indirectly, such as through participatorynotes or depositary receipts, may involve other risks such asthe risk that the counterparty may default or that theinvestment does not track the underlying security asexpected.

— Focused Investment Risk – Should the Fund focus itsinvestments in related, or a limited number of, countries,regions, sectors, or companies, this would create more riskand greater volatility than if the Fund’s investments wereless focused.

— Government and Regulatory Risk – Governmental andregulatory authorities in the United States and othercountries, have taken, and may in the future take, actionsintervening in the markets in which the Fund invests and inthe economy more generally. Governmental and regulatoryauthorities may also act to increase the scope or burden ofregulations applicable to the Fund or to the companies inwhich the Fund invests. The effects of these actions on themarkets generally, and Fund’s investment program inparticular, can be uncertain and could restrict the ability ofthe Fund to fully implement its investment strategies, eithergenerally, or with respect to certain securities, industries, orcountries. By contrast, markets in some non-U.S. countries

historically have been subject to little regulation or oversightby governmental or regulatory authorities, which couldheighten the risk of loss due to fraud or market failures inthose countries. Governments, agencies, or other regulatorybodies in any country may adopt or change laws orregulations that could adversely affect the Fund or themarket value of an instrument held by the Fund.

— Information Technology Risk – Cyber-attacks, disruptions, orfailures that affect the Fund’s service providers, counterparties,the securities markets generally, other market participants, orissuers of securities held by the Fund may adversely affect theFund and its shareholders, including by causing losses for theFund or impairing Fund operations.

— IPO Risk – The Fund may purchase securities in IPOs.These securities are subject to many of the same risks ofinvesting in companies with smaller market capitalizations.Securities issued in IPOs have no trading history, andinformation about the companies may be available for verylimited periods. In addition, the prices of securities sold inIPOs may be highly volatile.

— Large-Capitalization Securities Risk – Returns oninvestments in securities of large companies could trail thereturns on investments in securities of smaller and medium-sized companies. Larger companies may be unable torespond as quickly as smaller and medium-sized companiesto competitive challenges or to changes in business, product,financial, or other market conditions. Larger companies maynot be able to achieve or maintain growth at the high ratesthat may be achieved by well-managed smaller and medium-sized companies.

— Liquidity Risk – The Fund’s investments may be subject tolow trading volume, lack of a market maker, contractual lock-in periods or regulatory restrictions, and the Fund may holdlarge positions in particular securities. As a result, it may notbe possible to sell an investment at a particular time or at anacceptable price. Liquidity risk may be magnified duringperiods of changing interest rates, significant shareholderredemptions or market turmoil. Illiquid securities may tradeat a discount from comparable, more liquid investments andmay be subject to wide fluctuations in market value. In somecases, due to unanticipated levels of illiquidity the Fund mayseek to meet its redemption obligations wholly or in part bydistributions of assets in-kind.

— Market Disruption and Geopolitical Risk – The value of theFund’s investments could be adversely affected by eventsthat disrupt securities markets and adversely affect globalmarkets such as war, terrorism, public health crises, andgeopolitical events and by changes in non-U.S. and U.S.economic and political conditions. As a result of theseevents, the Fund could lose money, experience significantredemptions, encounter operational difficulties, and sufferother negative impacts.

— Market Risk – The value of the Fund’s investments will beaffected by fluctuations in the stock markets in which theFund is invested, factors affecting a particular industry orindustries, real or perceived adverse economic conditions,changes in interest or currency rates or adverse investor

sentiment generally. Declines in securities market prices mayreduce the net asset value of the Fund’s shares.

— New and Smaller-Sized Funds Risk – New funds andsmaller-sized funds will be subject to greater liquidity riskdue to their smaller asset bases and may be required to sellsecurities at disadvantageous times or prices due to a largeshareholder redemption. A fund that has been recentlyformed will have limited or no performance history forinvestors to evaluate and may not reach or maintain asufficient asset size to effectively implement its investmentstrategy.

— Non-U.S. Investment Risk – Non-U.S. securities are subjectto additional risks, including less liquidity, increased volatility,less transparency, withholding or other taxes, increasedvulnerability to adverse changes in local and globaleconomic conditions, less regulation, and possiblefluctuation in value due to adverse political conditions.Foreign portfolio transactions generally involve highercommission rates, transfer taxes, and custodial costs thansimilar transactions in the U.S.

— Service Provider Risk – The Fund will be affected by theManager’s investment techniques, analyses, assessmentsand employee retention. Similarly, adverse events orperformance failures at a service provider, such as humanerror, inadequate controls or insolvency, have the ability toadversely affect the Fund.

— Settlement Risk – The Fund may experience delays insettlement due to the different clearance and settlementprocedures in non-U.S. countries. Such delays may increasecredit risk to the Fund, limit the ability of the Fund to reinvestthe proceeds of a sale of securities, or prevent the Fundfrom selling securities at times and prices it considersdesirable.

— Small- and Medium-Capitalization Securities Risk – Securitiesof small- and medium-capitalization companies can be morevolatile due to various factors including more limited productlines, financial and management resources and marketdistribution channels, as well as shorter operating historiesand potentially reduced liquidity, especially during marketdeclines, than the securities of larger, more establishedcompanies.

— Valuation Risk – In certain circumstances, some of theFund’s portfolio holdings may be valued on the basis offactors other than market quotations by employing the fairvalue procedures adopted by the Board of Trustees of theTrust (the “Board”). This may occur more often in times ofmarket turmoil or reduced liquidity. Portfolio holdings that arevalued using techniques other than market quotations,including “fair valued” securities, may be subject to greaterfluctuation in their valuations from one day to the next than ifmarket quotations were used. There is no assurance that theFund could sell or close out a portfolio position for the valueestablished for it at any time, and it is possible that the Fundwould incur a loss because a portfolio position is sold orclosed out at a discount to the valuation established by theFund at that time.

Baillie Gifford Long Term Global Growth Fund

Investment ObjectiveBaillie Gifford Long Term Global Growth Fund seeks to providelong-term capital appreciation.

Fees and ExpensesThe tables below describe the fees and expenses that you maypay if you buy, hold, and sell shares of the Fund. You may payother fees, such as brokerage commissions and other fees tofinancial intermediaries, which are not reflected in the tables andexamples below.

Shareholder Fees(Fees paid directly from your investment)

Class K Institutional ClassNone None

Annual Fund Operating Expenses(Expenses that you pay each year as a percentage of the valueof your investment)

Class K Institutional ClassManagement Fees(a) 0.62% 0.62%Distribution (12b-1) Fees None NoneOther Expenses(b) 0.09% 0.17%Total Annual Fund Operating Expenses 0.71% 0.79%

(a) The Management Fee consists of an Advisory Fee and anAdministration and Supervisory Fee paid by the Fund to BaillieGifford Overseas Limited.

(b) Other Expenses differ due to sub-accounting expenses.

Example of ExpensesThe example below is intended to help you compare the cost ofinvesting in the Fund with the cost of investing in other mutualfunds. It assumes that you invest $10,000 in the Fund for the timeperiods indicated, regardless of whether or not you redeem yourshares at the end of such periods. It also assumes that yourinvestment has a 5% return each year and that the Fund’soperating expenses remain the same.

Although your actual costs may be higher or lower, based onthese assumptions, your expenses would be:

Class K Institutional Class1 Year $73 $813 Years $227 $2525 Years $395 $43910 Years $883 $978

Portfolio TurnoverThe Fund pays transaction costs, such as commissions, when itbuys and sells securities (or “turns over” its portfolio). A higherportfolio turnover rate may indicate higher transaction costs andmay result in higher taxes when Fund shares are held in ataxable account. These transaction costs, which are not reflectedin “Annual Fund Operating Expenses” or in the “Example ofExpenses” above, affect the Fund’s performance. During theFund’s most recent fiscal year, the Fund’s portfolio turnover ratewas 40% of the average value of its portfolio.

Principal Investment StrategiesThe Fund seeks to meet its objective by investing in a portfolio ofglobal equity securities, which include common stock and otherequity securities, without reference to benchmark constraints.

Under normal circumstances, the Fund invests at least 80% of itsnet assets (plus any borrowings for investment purposes) inequity securities. While the portfolio managers are notconstrained by geographic limitations, the Fund ordinarily investsin securities of issuers located in at least six different countries.In addition, under normal circumstances, the Fund will invest atleast 40% of its total assets in securities of companies locatedoutside the U.S. when market conditions are favorable, but, whenmarket conditions are not favorable, will invest at least 30% of itstotal assets in companies located outside the U.S. The Fund mayinvest in issuers located in emerging markets.

The Fund invests in equity securities either directly or indirectly,such as through depositary receipts, and may invest in preferredstocks, convertible securities and warrants. The Fund typicallyinvests primarily in issuers with a market capitalization of morethan $4 billion at the time of purchase and may participate ininitial public offerings (“IPOs”) and in securities offerings that arenot registered in the U.S.

The portfolio managers employ a bottom-up approach to stockselection and select investments without regard to thegeographic, industry, sector, or individual company weightings onany index. The portfolio managers focus on company researchand the long-term outlook of companies and industries. Ideascan come from a wide variety of sources, including, but notlimited to, research trips, company meetings, and relationshipswith industry thought leaders and academic institutions. Stockideas are normally researched to assess a range of factors,including: long-term growth potential, geographic and industrypositioning, competitive advantage, management, financialstrength and valuation. The portfolio managers generally selectsecurities of between 30 and 60 growth companies. The processcan result in significant exposure to a single country or a smallnumber of countries, and the Fund expects to have considerableexposure to Chinese companies including through China Ashares, which are common stocks and other equity securities thatare listed or traded on a Chinese stock exchange and which arequoted in renminbi. The Fund is a non-diversified fund, whichmeans that it may invest a relatively large percentage of itsassets in a small number of issuers, industries or sectors.The Fund aims to hold securities for long periods (typically5-10 years), which results in relatively low portfolio turnover andis in line with the Fund’s long-term investment outlook.

The Fund may invest without limitation in securities quoted ordenominated in currencies other than the U.S. dollar and mayhold such currencies. The Fund does not expect to engage incurrency hedging and thus expects to be fully exposed tocurrency fluctuations relative to the U.S. dollar.

Principal RisksThe Fund’s net asset value and returns will be impacted by theperformance of the underlying investments of the Fund. Aninvestment in the Fund is not a deposit in a bank and is notinsured or guaranteed by the Federal Deposit InsuranceCorporation or any other government agency. You could losemoney by investing in the Fund.

The principal risks of investing in the Fund (in alphabetical orderafter the first six risks) are:

— Investment Style Risk – Baillie Gifford Overseas Limited(the “Manager”) actively makes investment decisions for theFund through bottom-up stock selection. Accordingly, theFund will have risk characteristics that differ from itsbenchmark index. The Manager’s judgments about theattractiveness, relative value, or potential appreciation of aparticular stock may prove to be incorrect and cause theFund to lose money or underperform compared to itsbenchmark index. There can be no assurance that theManager’s investment decisions will produce the desiredresults.

— Growth Stock Risk – The prices of growth stocks may bebased largely on expectations of future earnings, and theirprices can decline rapidly and significantly in reaction tonegative news. Growth stocks may underperform stocks inother broad style categories (and the stock market as awhole) over any period of time and may shift in and out offavor with investors generally, sometimes rapidly, dependingon changes in market, economic, and other factors.

— Long-Term Investment Strategy Risk – The Fund pursues along-term investment approach, typically seeking returnsover a period of several years. This investment style maycause the Fund to lose money or underperform compared toits benchmark index or other mutual funds over extendedperiods of time, and the Fund may not perform as expectedin the long term. An investment in the Fund may be moresuitable for long-term investors who can bear the risk ofshort- or medium-term fluctuations in the value of the Fund’sportfolio.

— Non-Diversification Risk – The Fund is classified as a “non-diversified” fund. A non-diversified fund may hold a smallernumber of portfolio securities, with larger positions in eachsecurity it holds, than many other mutual funds. To the extentthe Fund invests in a relatively small number of issuers, adecline in the market value of a particular security held bythe Fund may affect its value more than if it invested in alarger number of issuers. The value of the Fund’s sharesmay be more volatile than the values of shares of morediversified funds. See also “Focused Investment Risk.”

— Non-U.S. Investment Risk – Non-U.S. securities are subjectto additional risks, including less liquidity, increased volatility,less transparency, withholding or other taxes, increasedvulnerability to adverse changes in local and globaleconomic conditions, less regulation, and possiblefluctuation in value due to adverse political conditions.Foreign portfolio transactions generally involve highercommission rates, transfer taxes, and custodial costs thansimilar transactions in the U.S.

— China Risk – Investing in securities of Chinese issuersinvolves certain risks and considerations not typicallyassociated with investing in securities of U.S. issuers,including, among others, more frequent trading suspensionsand government interventions (including by nationalization ofassets), currency exchange rate fluctuations or blockages,limits on the use of brokers and on foreign ownership,different financial reporting standards, higher dependence on

exports and international trade, potential for increased tradetariffs, sanctions, embargoes and other trade limitations, andcustody risks. U.S. sanctions or other investment restrictionscould preclude the Fund from investing in certain Chineseissuers or cause the Fund to sell investments at adisadvantageous time. Significant portions of the Chinesesecurities markets may become rapidly illiquid, as Chineseissuers have the ability to suspend the trading of their equitysecurities, and have shown a willingness to exercise thatoption in response to market volatility and other events.

— Asia Risk – Investing in securities of companies located in orwith exposure to Asian countries involves certain risks andconsiderations not typically associated with investing insecurities of U.S. issuers, including different financialreporting standards, currency exchange rate fluctuations,and highly regulated markets with the potential forgovernment interference. The economies of many Asiancountries are heavily dependent on international trade andon only a few industries or commodities and, as a result, canbe adversely affected by trade barriers, exchange controlsand other measures imposed or negotiated by the countrieswith which they trade. Some Asian securities may be lessliquid than U.S. or other foreign securities. See “China Risk”for additional details regarding the risks of investing in thatcountry.

Additionally, many of the economies of countries in Asia areconsidered emerging market or frontier market economies.These Asian economies are often characterized by highinflation, undeveloped financial service sectors, frequentcurrency fluctuations, devaluations, or restrictions, politicaland social instability, and less efficient markets. See“Emerging Markets Risk” for additional details regarding therisks of investing in such countries.

— Conflicts of Interest Risk – The Manager’s relationships withthe Fund’s institutional investor base may give rise to variousconflicts of interest, since the Manager will sometimes havean incentive to favor those shareholders over othershareholders in the Fund. In addition, the Manager serves asinvestment adviser to various clients other than the Fund,some of whom may pursue strategies that are substantiallysimilar or nearly identical to investment strategies pursuedby the Fund. This “side-by-side” management may give riseto various conflicts of interest, including, for example, inconnection with the fair allocation of trades among theManager’s clients or the sharing of different, more, or moretimely information regarding investment performance,portfolio holdings, strategy developments and/or theManager’s general market outlook. Furthermore, ifinvestment personnel of the Manager hold board or otherpositions at outside companies, they could be exposed tomaterial non-public information potentially impeding ordelaying a Fund’s ability to buy or sell certain investments, orthey could otherwise be restricted in their ability toparticipate in a Fund’s investment process.

— Focused Investment Risk – Because the Fund focuses itsinvestments in a limited number of companies, its investmentstrategy could result in more risk or greater volatility inreturns than if the Fund’s investments were less focused.

— Government and Regulatory Risk – Governmental andregulatory authorities in the United States and othercountries, have taken, and may in the future take, actionsintervening in the markets in which the Fund invests and inthe economy more generally.

— Small- and Medium-Capitalization SecuritiesRisk – Securities of small- and medium-capitalizationcompanies can be more volatile due to various factorsincluding more limited product lines, financial andmanagement resources and market distribution channels, aswell as shorter operating histories and potentially reducedliquidity, especially during market declines, than thesecurities of larger, more established companies.

— Valuation Risk – In certain circumstances, some of theFund’s portfolio holdings may be valued on the basis of

factors other than market quotations by employing the fairvalue procedures adopted by the Board of Trustees of theTrust (the “Board”). This may occur more often in times ofmarket turmoil or reduced liquidity. Portfolio holdings that arevalued using techniques other than market quotations,including “fair valued” securities, may be subject to greaterfluctuation in their valuations from one day to the next than ifmarket quotations were used. There is no assurance that theFund could sell or close out a portfolio position for the valueestablished for it at any time, and it is possible that the Fundwould incur a loss because a portfolio position is sold orclosed out at a discount to the valuation established by theFund at that time.

PerformanceThe bar chart and table below provide some indication of therisks of investing in the Fund by showing changes in the Fund’sannual total returns from year to year and by comparing theFund’s average annual total returns with those of the Fund’sbenchmark.

Baillie Gifford Positive Change Equities Fund

Investment ObjectiveBaillie Gifford Positive Change Equities Fund seeks capitalappreciation with an emphasis on investing in businesses thatdeliver positive change by contributing towards a moresustainable and inclusive world.

Fees and ExpensesThe tables below describe the fees and expenses that you maypay if you buy, hold, and sell shares of the Fund. You may payother fees, such as brokerage commissions and other fees tofinancial intermediaries, which are not reflected in the tables andexamples below.

Shareholder Fees(Fees paid directly from your investment)

Class K Institutional ClassNone None

Annual Fund Operating Expenses(Expenses that you pay each year as a percentage of the valueof your investment)

Class K Institutional ClassManagement Fees(a) 0.50% 0.50%Distribution (12b-1) Fees None NoneOther Expenses 0.52% 0.55%Total Annual Fund Operating Expenses 1.02% 1.05%Fee Waiver and/or Expense Reimbursement(b) (0.37)% (0.37)%Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement(b) 0.65% 0.68%

(a) The Management Fee consists of an Advisory Fee and anAdministration and Supervisory Fee paid by the Fund to BaillieGifford Overseas Limited.

(b) Baillie Gifford Overseas Limited has contractually agreed to waiveits fees and/or bear Other Expenses of the Fund until April 30, 2022to the extent that such Fund’s Total Annual Operating Expenses(excluding taxes, sub-accounting expenses and extraordinaryexpenses) exceed 0.65% for Class K and Institutional Class shares.This contractual agreement may only be terminated by the Board ofTrustees of the Trust. Expenses after waiver/reimbursementexceed 0.65% for Institutional Class due to sub-accountingexpenses of 0.03%.

Example of ExpensesThe example below is intended to help you compare the cost ofinvesting in the Fund with the cost of investing in other mutualfunds. It assumes that you invest $10,000 in the Fund for the timeperiods indicated, regardless of whether or not you redeem yourshares at the end of such periods. It also assumes that yourinvestment has a 5% return each year and that the Fund’soperating expenses remain the same. The example below alsoapplies any contractual expense waivers and/or expensereimbursements to the first year of each period listed in the table.

Although your actual costs may be higher or lower, based onthese assumptions, your expenses would be:

Class K Institutional Class1 Year $66 $693 Years $288 $2975 Years $527 $54310 Years $1,214 $1,249

Portfolio TurnoverThe Fund pays transaction costs, such as commissions, when itbuys and sells securities (or “turns over” its portfolio). A higherportfolio turnover rate may indicate higher transaction costs andmay result in higher taxes when Fund shares are held in ataxable account. These transaction costs, which are not reflectedin “Annual Fund Operating Expenses” or in the “Example ofExpenses” above, affect the Fund’s performance. During theFund’s most recent fiscal year, the Fund’s portfolio turnover ratewas 40% of the average value of its portfolio.

Principal Investment StrategiesThe Fund seeks to meet its objective by investing in a globalportfolio of equities, which include common stock and otherequity securities, of issuers located in countries of developed,emerging, and frontier markets. Under normal circumstances, theFund invests at least 80% of its net assets (plus any borrowingsfor investment purposes) in equity securities. The Fund investspredominantly in securities issued by companies located incountries represented in the MSCI ACWI Index, cash and cashequivalents.

The Fund invests in equity securities either directly or indirectly,such as through depositary receipts, and may invest in preferredstocks, convertible securities and warrants. The Fund is notconstrained with respect to market capitalization and mayparticipate in initial public offerings (“IPOs”) and in securitiesofferings that are not registered in the U.S.

The portfolio managers employ a bottom-up approach to stockselection and select companies without being constrained by theMSCI ACWI benchmark. The portfolio managers focus oncompany research and the long-term outlook of companies andindustries. Ideas can come from a wide variety of sources,including, but not limited to, research trips, company meetings,and relationships with industry thought leaders and academicinstitutions. Stock ideas are normally researched to assess arange of factors, including: long-term growth potential,geographic and industry positioning, competitive advantage,management, financial strength and valuation. The intendedoutcome is a portfolio of between 25 and 50 growth companieswith the potential to outperform the benchmark over the long termand which the portfolio managers consider to have coreambitions of delivering a positive change in at least one of thefollowing areas: social inclusion and education, healthcare, theenvironment, and addressing basic needs and aspirations of theworld’s poorest populations. In order to assess positive change inthese areas, Baillie Gifford Overseas Limited (the “Manager”) willmonitor the progress of each issuer using metrics and/ormilestones designed by the Manager. With respect to each area,the Manager pursues an active, positive approach; investmentdecisions are generally not made on the basis of negative“screening” of companies viewed as socially irresponsible.

process can result in significant exposure to a single country or asmall number of countries, which in recent periods has includedJapan.

The Fund is a non-diversified fund, which means that it mayinvest a relatively large percentage of its assets in a smallnumber of issuers, industries or sectors. The Fund aims to holdsecurities for long periods (typically 5-10 years), which results inrelatively low portfolio turnover and is in line with the Fund’s long-term investment outlook.

The Fund may invest without limitation in securities quoted ordenominated in currencies other than the U.S. dollar and mayhold such currencies. The Fund does not expect to engage incurrency hedging and thus expects to be fully exposed tocurrency fluctuations relative to the U.S. dollar.

Principal RisksThe Fund’s net asset value and returns will be impacted by theperformance of the underlying investments of the Fund. Aninvestment in the Fund is not a deposit in a bank and is notinsured or guaranteed by the Federal Deposit InsuranceCorporation or any other government agency. You could losemoney by investing in the Fund.

The principal risks of investing in the Fund (in alphabetical orderafter the first five risks) are:

— Investment Style Risk – The Manager actively makesinvestment decisions for the Fund through bottom-up stockselection. Accordingly, the Fund will have risk characteristicsthat differ from its benchmark index. The Manager’sjudgments about the attractiveness, relative value, orpotential appreciation of a particular stock may prove to beincorrect and cause the Fund to lose money or underperformcompared to its benchmark index. There can be noassurance that the Manager’s investment decisions willproduce the desired results.

— Growth Stock Risk – The prices of growth stocks may bebased largely on expectations of future earnings, and theirprices can decline rapidly and significantly in reaction tonegative news. Growth stocks may underperform stocks inother broad style categories (and the stock market as awhole) over any period of time and may shift in and out offavor with investors generally, sometimes rapidly, dependingon changes in market, economic, and other factors.

— Long-Term Investment Strategy Risk – The Fund pursues along-term investment approach, typically seeking returnsover a period of several years. This investment style maycause the Fund to lose money or underperform compared toits benchmark index or other mutual funds over extendedperiods of time, and the Fund may not perform as expectedin the long term. An investment in the Fund may be moresuitable for long-term investors who can bear the risk ofshort- or medium-term fluctuations in the value of the Fund’sportfolio.

— Non-Diversification Risk – The Fund is classified as a “non-diversified” fund. Because the Fund may invest a relativelylarge percentage of its assets in a single issuer or smallnumber of issuers, its performance could be closely tied to

the value of that one issuer or those few issuers, and couldbe more volatile than the performance of diversified funds.

— Impact Risk – A Fund may not be successful in assessingand identifying companies that have or will have a positiveimpact or support a given position. In some circumstances,companies could ultimately have a negative impact, or noimpact, on addressing a global challenge, or onenvironmental, social and/or governance matters. See also“Socially Responsible Investing Risk.”

— Asia Risk – Investing in securities of companies located in orwith exposure to Asian countries involves certain risks andconsiderations not typically associated with investing insecurities of U.S. issuers, including different financialreporting standards, currency exchange rate fluctuations,and highly regulated markets with the potential forgovernment interference. The economies of many Asiancountries are heavily dependent on international trade andon only a few industries or commodities and, as a result, canbe adversely affected by trade barriers, exchange controlsand other measures imposed or negotiated by the countrieswith which they trade. Some Asian securities may be lessliquid than U.S. or other foreign securities. See “Japan Risk”for additional details regarding the risks of investing in thatcountry.

Additionally, many of the economies of countries in Asia areconsidered emerging market or frontier market economies.These Asian economies are often characterized by highinflation, undeveloped financial service sectors, frequentcurrency fluctuations, devaluations, or restrictions, politicaland social instability, and less efficient markets. See“Emerging Markets Risk” and “Frontier Markets Risk” foradditional details regarding the risks of investing in suchcountries.

— Conflicts of Interest Risk – The Manager’s relationships withthe Fund’s institutional investor base may give rise to variousconflicts of interest, since the Manager will sometimes havean incentive to favor those shareholders over othershareholders in the Fund. In addition, the Manager serves asinvestment adviser to various clients other than the Fund,some of whom may pursue strategies that are substantiallysimilar or nearly identical to investment strategies pursuedby the Fund. This “side-by-side” management may give riseto various conflicts of interest, including, for example, inconnection with the fair allocation of trades among theManager’s clients or the sharing of different, more, or moretimely information regarding investment performance,portfolio holdings, strategy developments and/or theManager’s general market outlook. Furthermore, ifinvestment personnel of the Manager hold board or otherpositions at outside companies, they could be exposed tomaterial non-public information potentially impeding ordelaying a Fund’s ability to buy or sell certain investments, orthey could otherwise be restricted in their ability toparticipate in a Fund’s investment process.

— Currency Risk – The Fund may realize a loss if it hasexposure to a non-U.S. currency, and this non-U.S. currencydeclines in value, relative to the U.S. dollar. The Fund doesnot expect to engage in currency hedging and thus expects

to be fully exposed to currency fluctuations relative to theU.S. dollar.

— Emerging Markets Risk – To the extent the Fund invests inemerging market securities, the Fund may be exposed togreater market, credit, currency, liquidity, legal, political,technical and other risks different from, or greater than, therisks of investing in developed markets.

— Equity Securities Risk – Equity securities may react morestrongly to changes in an issuer’s financial condition orprospects than other securities of the same issuer. Investingin equity securities indirectly, such as through participatorynotes or depositary receipts, may involve other risks such asthe risk that the counterparty may default or that theinvestment does not track the underlying security asexpected.

— Focused Investment Risk – Because the Fund focuses itsinvestments in a limited number of companies, its investmentstrategy could result in more risk or greater volatility inreturns than if the Fund’s investments were less focused.

— Frontier Markets Risk – Frontier markets are those emergingmarkets that are considered to be among the smallest, leastmature and least liquid and, as a result, may be more volatileand less liquid than investments in more developed marketsor in other emerging market countries. Emerging marketsrisk may be especially heightened in frontier markets.

— Government and Regulatory Risk – Governmental andregulatory authorities in the United States and othercountries, have taken, and may in the future take, actionsintervening in the markets in which the Fund invests and inthe economy more generally. Governmental and regulatoryauthorities may also act to increase the scope or burden ofregulations applicable to the Fund or to the companies inwhich the Fund invests. The effects of these actions on themarkets generally, and Fund’s investment program inparticular, can be uncertain and could restrict the ability ofthe Fund to fully implement its investment strategies, eithergenerally, or with respect to certain securities, industries, orcountries. By contrast, markets in some non-U.S. countrieshistorically have been subject to little regulation or oversightby governmental or regulatory authorities, which couldheighten the risk of loss due to fraud or market failures inthose countries. Governments, agencies, or other regulatorybodies in any country may adopt or change laws orregulations that could adversely affect the Fund or themarket value of an instrument held by the Fund.

— Information Technology Risk – Cyber-attacks, disruptions, orfailures that affect the Fund’s service providers, counterparties,the securities markets generally, other market participants, orissuers of securities held by the Fund may adversely affect theFund and its shareholders, including by causing losses for theFund or impairing Fund operations.

— IPO Risk – The Fund may purchase securities in IPOs.These securities are subject to many of the same risks ofinvesting in companies with smaller market capitalizations.Securities issued in IPOs have no trading history, andinformation about the companies may be available for very

limited periods. In addition, the prices of securities sold inIPOs may be highly volatile.

— Japan Risk – The Japanese economy has only recentlyemerged from a prolonged economic downturn. Since theyear 2000, Japan’s economic growth rate has remainedrelatively low, and it may remain low in the future. Japan’seconomy is characterized by an aging demographic,declining population, large government debt, and a highlyregulated labor market. In the longer term, Japan will have toaddress the effects of an aging population, including theimpact of a shrinking work force and higher welfare costs.Japan’s economic recovery has been affected by economicdistress resulting from a number of natural disasters,including disasters that caused damage to nuclear powerplants in the region. Such environmental catastrophes havecaused Japan’s financial markets to fluctuate dramatically.Japan continues to be subject to the risk of natural disasters,such as earthquakes, volcanic eruptions, typhoons andtsunamis, which could negatively affect the Japaneseeconomy.

— Large-Capitalization Securities Risk – Returns oninvestments in securities of large companies could trail thereturns on investments in securities of smaller and medium-sized companies. Larger companies may be unable torespond as quickly as smaller and medium-sized companiesto competitive challenges or to changes in business, product,financial, or other market conditions. Larger companies maynot be able to achieve or maintain growth at the high ratesthat may be achieved by well-managed smaller and medium-sized companies.

— Liquidity Risk – The Fund’s investments may be subject tolow trading volume, lack of a market maker, contractual lock-in periods or regulatory restrictions, and the Fund may holdlarge positions in particular securities. As a result, it may notbe possible to sell an investment at a particular time or at anacceptable price. Liquidity risk may be magnified duringperiods of changing interest rates, significant shareholderredemptions or market turmoil. Illiquid securities may tradeat a discount from comparable, more liquid investments andmay be subject to wide fluctuations in market value. In somecases, due to unanticipated levels of illiquidity the Fund mayseek to meet its redemption obligations wholly or in part bydistributions of assets in-kind.

— Market Disruption and Geopolitical Risk – The value of theFund’s investments could be adversely affected by eventsthat disrupt securities markets and adversely affect globalmarkets such as war, terrorism, public health crises, andgeopolitical events and by changes in non-U.S. and U.S.economic and political conditions. As a result of theseevents, the Fund could lose money, experience significantredemptions, encounter operational difficulties, and sufferother negative impacts.

— Market Risk – The value of the Fund’s investments will beaffected by fluctuations in the stock markets in which theFund is invested, factors affecting a particular industry orindustries, real or perceived adverse economic conditions,changes in interest or currency rates or adverse investor

sentiment generally. Declines in securities market prices mayreduce the net asset value of the Fund’s shares.

— Non-U.S. Investment Risk – Non-U.S. securities are subjectto additional risks, including less liquidity, increased volatility,less transparency, withholding or other taxes, increasedvulnerability to adverse changes in local and globaleconomic conditions, less regulation, and possiblefluctuation in value due to adverse political conditions.Foreign portfolio transactions generally involve highercommission rates, transfer taxes, and custodial costs thansimilar transactions in the U.S.

— Service Provider Risk – The Fund will be affected by theManager’s investment techniques, analyses, assessmentsand employee retention. Similarly, adverse events orperformance failures at a service provider, such as humanerror, inadequate controls or insolvency, have the ability toadversely affect the Fund.

— Settlement Risk – The Fund may experience delays insettlement due to the different clearance and settlementprocedures in non-U.S. countries. Such delays may increasecredit risk to the Fund, limit the ability of the Fund to reinvestthe proceeds of a sale of securities, or prevent the Fundfrom selling securities at times and prices it considersdesirable.

— Small- and Medium-Capitalization SecuritiesRisk – Securities of small- and medium-capitalizationcompanies can be more volatile due to various factorsincluding more limited product lines, financial andmanagement resources and market distribution channels, aswell as shorter operating histories and potentially reducedliquidity, especially during market declines, than thesecurities of larger, more established companies.

— Socially Responsible Investing Risk – The Fund’sincorporation of environmental, social and/or governanceconsiderations in its investment process may cause it tomake different investments than funds that have a similarinvestment universe and/or investment style but that do notincorporate such considerations in their strategy orinvestment processes. As a result, such Fund may foregoopportunities to buy certain securities when it mightotherwise be advantageous to do so, or sell securities whenit might be otherwise disadvantageous for it to do so. Seealso “Impact Risk.”

— Valuation Risk – In certain circumstances, some of theFund’s portfolio holdings may be valued on the basis offactors other than market quotations by employing the fairvalue procedures adopted by the Board of Trustees of theTrust (the “Board”). This may occur more often in times ofmarket turmoil or reduced liquidity. Portfolio holdings that arevalued using techniques other than market quotations,including “fair valued” securities, may be subject to greaterfluctuation in their valuations from one day to the next than ifmarket quotations were used. There is no assurance that theFund could sell or close out a portfolio position for the valueestablished for it at any time, and it is possible that the Fundwould incur a loss because a portfolio position is sold or

closed out at a discount to the valuation established by theFund at that time.

PerformanceThe bar chart and table below provide some indication of therisks of investing in the Fund by showing changes in the Fund’sannual total returns from year to year and by comparing theFund’s average annual total returns with those of the Fund’sbenchmark. Past performance (before and after taxes) is not anindication of future performance.

Baillie Gifford U.S. Discovery Fund

Investment ObjectiveBaillie Gifford U.S. Discovery Fund seeks capital appreciation.

Fees and ExpensesThe tables below describe the fees and expenses that you maypay if you buy, hold, and sell shares of the Fund. You may payother fees, such as brokerage commissions and other fees tofinancial intermediaries, which are not reflected in the tables andexamples below.

Shareholder Fees(Fees paid directly from your investment)

Class K Institutional ClassNone None

Annual Fund Operating Expenses(Expenses that you pay each year as a percentage of the valueof your investment)

Class K Institutional ClassManagement Fees(a) 0.67% 0.67%Distribution (12b-1) Fees None NoneOther Expenses(b) 15.65% 15.80%Total Annual Fund Operating Expenses 16.32% 16.47%Fee Waiver and/or Expense Reimbursement(c) (15.50)% (15.50)%Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement(c) 0.82% 0.97%

(a) The Management Fee consists of an Advisory Fee and anAdministration and Supervisory Fee paid by the Fund to BaillieGifford Overseas Limited.

(b) Class K and Institutional Class were unfunded as of December 31,2020. Therefore Other Expenses have been estimated for thecurrent fiscal year assuming Fund assets of $1 million.

(c) Baillie Gifford Overseas Limited has contractually agreed to waiveits fees and/or bear other expenses of the Fund until April 30, 2022to the extent that the Fund’s Total Annual Fund OperatingExpenses (excluding taxes, sub-accounting expenses andextraordinary expenses) exceed 0.82% for Class K and InstitutionalClass shares. This contractual agreement may only be terminatedby the Board of Trustees of the Trust. Expenses afterwaiver/reimbursement exceed 0.82% for Institutional Class due toestimated sub-accounting expenses of 0.15%.

Example of ExpensesThe example below is intended to help you compare the cost ofinvesting in the Fund with the cost of investing in other mutualfunds. It assumes that you invest $10,000 in the Fund for the timeperiods indicated, regardless of whether or not you redeem yourshares at the end of such periods. It also assumes that yourinvestment has a 5% return each year and that the Fund’soperating expenses remain the same. The example below alsoapplies any contractual expense waivers and/or expensereimbursements to the first year of each period listed in the table.

Although your actual costs may be higher or lower, based onthese assumptions, your expenses would be:

Class K Institutional Class1 Year $84 $993 Years $3,110 $3,144

Portfolio TurnoverThe Fund pays transaction costs, such as commissions, when itbuys and sells securities (or “turns over” its portfolio). A higherportfolio turnover rate may indicate higher transaction costs andmay result in higher taxes when Fund shares are held in ataxable account. These transaction costs, which are not reflectedin “Annual Fund Operating Expenses” or in the “Example ofExpenses” above, affect the Fund’s performance. Because theFund has not commenced operations, it does not have a portfolioturnover rate.

Principal Investment StrategiesThe Fund will seek to meet its objective by investing in a portfolioof common stocks and other equity securities of smaller, publiclytraded U.S. companies that are perceived to be innovative andentrepreneurial, such as by disrupting existing markets orcreating entirely new ones, and that have strong growth potential.

In selecting portfolio investments, the portfolio managers seek todiscover innovative and entrepreneurial companies through aprocess that involves considering, among other things, a potentialholding’s market opportunity, competitive edge, corporate culture,and scalability prospects. The inclusion of “discovery” in theFund’s name does not reflect an intent to invest in any particulartype of investment or industry.

When selecting companies for initial inclusion in the portfolio, theportfolio managers focus on publicly traded companies with amarket capitalization in the region of $10 billion or lower at thetime of initial purchase. Because the Fund will be managed inaccordance with an established model investment strategyoperated by the portfolio managers, the Fund’s portfolio isexpected to include a number of companies with marketcapitalizations of greater than $10 billion at the time the Fundcommences investment operations. These are companies thathad market capitalizations of less than $10 billion at the time ofinclusion in the model investment strategy, but which havesubsequently grown. In addition, because the Fund expects tocontinue to hold, and potentially increase its investment in,portfolio companies whose market capitalizations increasesubsequent to the initial purchase, the Fund expects over time tohave a substantial portion of its portfolio invested in companieswith a market capitalization in excess of $10 billion. Undernormal circumstances, the Fund will invest at least 80% of itsassets in securities of small- and mid-capitalization companies,which the Manager defines as companies with marketcapitalizations of $30 billion or less.

Under normal circumstances, the Fund will invest at least 80% ofits net assets (plus any borrowings for investment purposes) insecurities of issuers located in the U.S. The Fund will invest inequity securities either directly or indirectly, such as throughdepositary receipts, and may invest in preferred stocks,convertible securities and warrants. The Fund may participate ininitial public offerings (“IPOs”).

Baillie Gifford Funds – Prospectus

The portfolio managers will select companies without beingconstrained by the Fund’s Benchmark, the Russell 2500 GrowthIndex. The portfolio managers focus on company research andthe long-term outlook of companies and industries. Ideas cancome from a wide variety of sources, including, but not limited to,research trips, company meetings, and relationships with industrythought leaders and academic institutions. Stock ideas arenormally researched to assess a range of factors, including:long-term growth potential, geographic and industry positioning,competitive advantage, management, financial strength andvaluation. The intended outcome is a non-diversified portfolio ofbetween 40 and 75 growth companies with the potential tooutperform the benchmark over the long term. The Fund intendsto operate as a non-diversified fund, which means that it mayinvest a relatively large percentage of its assets in a smallnumber of issuers, industries, or sectors. The Fund aims to holdsecurities for long periods (typically 5-10 years), which isexpected to result in relatively low portfolio turnover and be in linewith the Fund’s long-term investment outlook.

Principal RisksThe Fund’s net asset value and returns will be impacted by theperformance of the underlying investments of the Fund. Aninvestment in the Fund is not a deposit in a bank and is notinsured or guaranteed by the Federal Deposit InsuranceCorporation or any other government agency. You could losemoney by investing in the Fund.

The principal risks of investing in the Fund (in alphabetical orderafter the first six risks) are:

— Small- and Medium-Capitalization SecuritiesRisk – Securities of small- and medium-capitalizationcompanies can be more volatile due to various factorsincluding more limited product lines, financial andmanagement resources and market distribution channels, aswell as shorter operating histories and potentially reducedliquidity, especially during market declines, than thesecurities of larger, more established companies.

— Growth Stock Risk – The prices of growth stocks may bebased largely on expectations of future earnings, and theirprices can decline rapidly and significantly in reaction tonegative news. Growth stocks may underperform stocks inother broad style categories (and the stock market as awhole) over any period of time and may shift in and out offavor with investors generally, sometimes rapidly, dependingon changes in market, economic, and other factors.

— Investment Style Risk – Baillie Gifford Overseas Limited(the “Manager”) actively makes investment decisions for theFund through bottom-up stock selection. Accordingly, theFund will have risk characteristics that differ from itsbenchmark index. The Manager’s judgments about theattractiveness, relative value, or potential appreciation of aparticular stock may prove to be incorrect and cause theFund to lose money or underperform compared to itsbenchmark index. There can be no assurance that theManager’s investment decisions will produce the desiredresults.

— Long-Term Investment Strategy Risk – The Fund pursues along-term investment approach, typically seeking returns

over a period of several years. This investment style maycause the Fund to lose money or underperform compared toits benchmark index or other mutual funds over extendedperiods of time, and the Fund may not perform as expectedin the long term. An investment in the Fund may be moresuitable for long-term investors who can bear the risk ofshort- or medium-term fluctuations in the value of the Fund’sportfolio.

— Geographic Focus Risk – A fund that focuses its investmentsin a limited number of countries or geographic regions willnot offer the same level of diversification of risks as a morebroadly global fund because it will be exposed to a smallergeographic area. The performance of a fund that is lessdiversified across countries or geographic regions will beclosely tied to market, currency, economic, political,environmental, or regulatory conditions and developments inthe countries or regions in which the fund invests, and maybe more volatile than the performance of a moregeographically-diversified portfolio.

— Non-Diversification Risk – The Fund is classified as a “non-diversified” fund. A non-diversified fund may hold a smallernumber of portfolio securities, with larger positions in eachsecurity it holds, than many other mutual funds. To the extentthe Fund invests in a relatively small number of issuers, adecline in the market value of a particular security held bythe Fund may affect its value more than if it invested in alarger number of issuers. The value of the Fund’s sharesmay be more volatile than the values of shares of morediversified funds. See also “Focused Investment Risk.”

— Conflicts of Interest Risk – The Manager’s relationships withthe Fund’s institutional investor base may give rise to variousconflicts of interest, since the Manager will sometimes havean incentive to favor those shareholders over othershareholders in the Fund. In addition, the Manager serves asinvestment adviser to various clients other than the Fund,some of whom may pursue strategies that are substantiallysimilar or nearly identical to investment strategies pursuedby the Fund. This “side-by-side” management may give riseto various conflicts of interest, including, for example, inconnection with the fair allocation of trades among theManager’s clients or the sharing of different, more, or moretimely information regarding investment performance,portfolio holdings, strategy developments and/or theManager’s general market outlook. Furthermore, ifinvestment personnel of the Manager hold board or otherpositions at outside companies, they could be exposed tomaterial non-public information potentially impeding ordelaying a Fund’s ability to buy or sell certain investments, orthey could otherwise be restricted in their ability toparticipate in a Fund’s investment process.

— Equity Securities Risk – Equity securities may react morestrongly to changes in an issuer’s financial condition orprospects than other securities of the same issuer. Investingin equity securities indirectly, such as through participatorynotes or depositary receipts, may involve other risks such asthe risk that the counterparty may default or that theinvestment does not track the underlying security asexpected.

Baillie Gifford Funds – Prospectus

— Focused Investment Risk – Should the Fund focus itsinvestments in related, or a limited number of, countries,regions, sectors, or companies, this would create more riskand greater volatility than if the Fund’s investments wereless focused.

— Government and Regulatory Risk – Governmental andregulatory authorities in the United States and othercountries, have taken, and may in the future take, actionsintervening in the markets in which the Fund invests and inthe economy more generally. Governmental and regulatoryauthorities may also act to increase the scope or burden ofregulations applicable to the Fund or to the companies inwhich the Fund invests. The effects of these actions on themarkets generally, and Fund’s investment program inparticular, can be uncertain and could restrict the ability ofthe Fund to fully implement its investment strategies, eithergenerally, or with respect to certain securities, industries, orcountries. By contrast, markets in some non-U.S. countrieshistorically have been subject to little regulation or oversightby governmental or regulatory authorities, which couldheighten the risk of loss due to fraud or market failures inthose countries. Governments, agencies, or other regulatorybodies in any country may adopt or change laws orregulations that could adversely affect the Fund or themarket value of an instrument held by the Fund.

— Information Technology Risk – Cyber-attacks, disruptions, orfailures that affect the Fund’s service providers, counterparties,the securities markets generally, other market participants, orissuers of securities held by the Fund may adversely affect theFund and its shareholders, including by causing losses for theFund or impairing Fund operations.

— IPO Risk – The Fund may purchase securities in IPOs.These securities are subject to many of the same risks ofinvesting in companies with smaller market capitalizations.Securities issued in IPOs have no trading history, andinformation about the companies may be available for verylimited periods. In addition, the prices of securities sold inIPOs may be highly volatile.

— Liquidity Risk – The Fund’s investments may be subject tolow trading volume, lack of a market maker, contractual lock-in periods or regulatory restrictions, and the Fund may holdlarge positions in particular securities. As a result, it may notbe possible to sell an investment at a particular time or at anacceptable price. Illiquid securities may trade at a discountfrom comparable, more liquid investments and may besubject to wide fluctuations in market value. In some cases,due to unanticipated levels of illiquidity the Fund may seek tomeet its redemption obligations wholly or in part bydistributions of assets in-kind.

— Market Disruption and Geopolitical Risk – The value of theFund’s investments could be adversely affected by eventsthat disrupt securities markets and adversely affect globalmarkets and by changes in non-U.S. and U.S. economic andpolitical conditions.

— Market Risk – The value of the Fund’s investments will beaffected by fluctuations in the stock markets in which theFund is invested, factors affecting a particular industry orindustries, real or perceived adverse economic conditions,

changes in interest or currency rates or adverse investorsentiment generally. Declines in securities market prices mayreduce the net asset value of the Fund’s shares.

— New and Smaller-Sized Funds Risk – New funds andsmaller-sized funds will be subject to greater liquidity riskdue to their smaller asset bases and may be required to sellsecurities at disadvantageous times or prices due to a largeshareholder redemption. A fund that has been recentlyformed will have limited or no performance history forinvestors to evaluate and may not reach or maintain asufficient asset size to effectively implement its investmentstrategy.

— Service Provider Risk – The Fund will be affected by theManager’s investment techniques, analyses, assessmentsand employee retention. Similarly, adverse events orperformance failures at a service provider, such as humanerror, inadequate controls or insolvency, have the ability toadversely affect the Fund.

— Valuation Risk – Some portfolio holdings may be valued onthe basis of factors other than market quotations. This mayoccur more often in times of market turmoil or reducedliquidity. Portfolio holdings that are valued using techniquesother than market quotations, including “fair valued”securities, may be subject to greater fluctuation in theirvaluations from one day to the next than if market quotationswere used. There is no assurance that the Fund could sell orclose out a portfolio position for the value established for it atany time, and it is possible that the Fund would incur a lossbecause a portfolio position is sold or closed out at adiscount to the valuation established by the Fund at thattime.

PerformanceThe Fund had not commenced operations as of December 31,2020. Accordingly, performance data is not included. Whenperformance data becomes available, it will be posted to thefollowing website: http://USmutualfund.bailliegifford.com.

(a) The Management Fee consists of an Advisory Fee and anAdministration and Supervisory Fee paid by the Fund to BaillieGifford Overseas Limited.

(b) Baillie Gifford Overseas Limited has contractually agreed to waiveits fees and/or bear Other Expenses of the Fund until April 30, 2022to the extent that such Fund’s Total Annual Operating Expenses(excluding taxes, sub-accounting expenses and extraordinaryexpenses) exceed 0.65% for Class K and Institutional Class shares.This contractual agreement may only be terminated by the Board ofTrustees of the Trust. Expenses after waiver/reimbursementexceed 0.65% for Institutional Class due to sub-accountingexpenses of 0.09%.

Example of ExpensesThe example below is intended to help you compare the cost ofinvesting in the Fund with the cost of investing in other mutualfunds. It assumes that you invest $10,000 in the Fund for the timeperiods indicated, regardless of whether or not you redeem yourshares at the end of such periods. It also assumes that yourinvestment has a 5% return each year and that the Fund’soperating expenses remain the same. The example below alsoapplies any contractual expense waivers and/or expensereimbursements to the first year of each period listed in the table.

Although your actual costs may be higher or lower, based onthese assumptions, your expenses would be:

Class K Institutional Class1 Year $66 $763 Years $277 $3055 Years $505 $55410 Years $1,161 $1,265

Portfolio TurnoverThe Fund pays transaction costs, such as commissions, when itbuys and sells securities (or “turns over” its portfolio). A higherportfolio turnover rate may indicate higher transaction costs andmay result in higher taxes when Fund shares are held in ataxable account. These transaction costs, which are not reflectedin “Annual Fund Operating Expenses” or in the “Example ofExpenses” above, affect the Fund’s performance. During theFund’s most recent fiscal year, the Fund’s portfolio turnover ratewas 33% of the average value of its portfolio.

Principal Investment StrategiesThe Fund seeks to meet its objective by investing in a portfolio ofequities, which include common stock and other equity securities,of issuers located in the U.S.

The portfolio managers seek to identify exceptional growthbusinesses in the U.S. and to own them for long enough that theadvantages of their business models and the strength of theircultures support positive relative performance over the long term.

Under normal circumstances, the Fund invests at least 80% of itsnet assets (plus any borrowings for investment purposes) incommon stocks and other equity securities of companies whoseprincipal activities are in the U.S. The Fund invests in equitysecurities either directly or indirectly, such as through depositaryreceipts, and may invest in preferred stocks, convertiblesecurities and warrants. The Fund typically invests primarily inissuers with a market capitalization of more than $1.5 billion atthe time of purchase and may participate in initial public offerings(“IPOs”).

The portfolio managers employ a bottom-up approach to stockselection and select companies without being constrained by abenchmark. They generally invest in a portfolio of between 30and 50 growth companies. The portfolio managers focus oncompany research and the long-term outlook of companies andindustries. Ideas can come from a wide variety of sources,including, but not limited to, research trips, company meetings,and relationships with industry thought leaders and academicinstitutions. Stock ideas are normally researched to assess arange of factors, including: long-term growth potential,geographic and industry positioning, competitive advantage,management, financial strength and valuation. The Fund is anon-diversified fund, which means that it may invest a relativelylarge percentage of its assets in a small number of issuers,industries or sectors. The Fund aims to hold securities for longperiods (typically 5-10 years), which results in relatively lowportfolio turnover and is in line with the Fund’s long-terminvestment outlook.

— Conflicts of Interest Risk – The Manager’s relationships withthe Fund’s institutional investor base may give rise to variousconflicts of interest, since the Manager will sometimes havean incentive to favor those shareholders over othershareholders in the Fund. In addition, the Manager serves asinvestment adviser to various clients other than the Fund,some of whom may pursue strategies that are substantiallysimilar or nearly identical to investment strategies pursuedby the Fund. This “side-by-side” management may give riseto various conflicts of interest, including, for example, inconnection with the fair allocation of trades among theManager’s clients or the sharing of different, more, or moretimely information regarding investment performance,portfolio holdings, strategy developments and/or theManager’s general market outlook. Furthermore, ifinvestment personnel of the Manager hold board or otherpositions at outside companies, they could be exposed tomaterial non-public information potentially impeding ordelaying a Fund’s ability to buy or sell certain investments, orthey could otherwise be restricted in their ability toparticipate in a Fund’s investment process.

— Equity Securities Risk – Equity securities may react morestrongly to changes in an issuer’s financial condition orprospects than other securities of the same issuer. Investingin equity securities indirectly, such as through participatorynotes or depositary receipts, may involve other risks such asthe risk that the counterparty may default or that theinvestment does not track the underlying security asexpected.

— Focused Investment Risk – Because the Fund focuses itsinvestments in a limited number of companies, its investmentstrategy could result in more risk or greater volatility inreturns than if the Fund’s investments were less focused.

— Government and Regulatory Risk – Governmental andregulatory authorities in the United States and othercountries, have taken, and may in the future take, actionsintervening in the markets in which the Fund invests and inthe economy more generally. Governmental and regulatoryauthorities may also act to increase the scope or burden ofregulations applicable to the Fund or to the companies inwhich the Fund invests. The effects of these actions on themarkets generally, and Fund’s investment program inparticular, can be uncertain and could restrict the ability ofthe Fund to fully implement its investment strategies, eithergenerally, or with respect to certain securities, industries, orcountries. By contrast, markets in some non-U.S. countrieshistorically have been subject to little regulation or oversightby governmental or regulatory authorities, which couldheighten the risk of loss due to fraud or market failures inthose countries. Governments, agencies, or other regulatorybodies in any country may adopt or change laws orregulations that could adversely affect the Fund or themarket value of an instrument held by the Fund.

— Information Technology Risk – Cyber-attacks, disruptions, orfailures that affect the Fund’s service providers, counterparties,the securities markets generally, other market participants, or

issuers of securities held by the Fund may adversely affect theFund and its shareholders, including by causing losses for theFund or impairing Fund operations.

— IPO Risk – The Fund may purchase securities in IPOs.These securities are subject to many of the same risks ofinvesting in companies with smaller market capitalizations.Securities issued in IPOs have no trading history, andinformation about the companies may be available for verylimited periods. In addition, the prices of securities sold inIPOs may be highly volatile.

— Large-Capitalization Securities Risk – Returns oninvestments in securities of large companies could trail thereturns on investments in securities of smaller and medium-sized companies. Larger companies may be unable torespond as quickly as smaller and medium-sized companiesto competitive challenges or to changes in business, product,financial, or other market conditions. Larger companies maynot be able to achieve or maintain growth at the high ratesthat may be achieved by well-managed smaller and medium-sized companies.

— Liquidity Risk – The Fund’s investments may be subject tolow trading volume, lack of a market maker, contractual lock-in periods or regulatory restrictions, and the Fund may holdlarge positions in particular securities. As a result, it may notbe possible to sell an investment at a particular time or at anacceptable price. Liquidity risk may be magnified duringperiods of changing interest rates, significant shareholderredemptions or market turmoil. Illiquid securities may tradeat a discount from comparable, more liquid investments andmay be subject to wide fluctuations in market value. In somecases, due to unanticipated levels of illiquidity the Fund mayseek to meet its redemption obligations wholly or in part bydistributions of assets in-kind.

— Market Disruption and Geopolitical Risk – The value of theFund’s investments could be adversely affected by eventsthat disrupt securities markets and adversely affect globalmarkets such as war, terrorism, public health crises, andgeopolitical events and by changes in non-U.S. and U.S.economic and political conditions. As a result of theseevents, the Fund could lose money, experience significantredemptions, encounter operational difficulties, and sufferother negative impacts.

— Market Risk – The value of the Fund’s investments will beaffected by fluctuations in the stock markets in which theFund is invested, factors affecting a particular industry orindustries, real or perceived adverse economic conditions,changes in interest or currency rates or adverse investorsentiment generally. Declines in securities market prices mayreduce the net asset value of the Fund’s shares.

— New and Smaller-Sized Funds Risk – New funds andsmaller-sized funds will be subject to greater liquidity riskdue to their smaller asset bases and may be required to sellsecurities at disadvantageous times or prices due to a largeshareholder redemption. A fund that has been recentlyformed will have limited or no performance history forinvestors to evaluate and may not reach or maintain asufficient asset size to effectively implement its investmentstrategy.

— Service Provider Risk – The Fund will be affected by theManager’s investment techniques, analyses, assessmentsand employee retention. Similarly, adverse events orperformance failures at a service provider, such as humanerror, inadequate controls or insolvency, have the ability toadversely affect the Fund.

— Small- and Medium-Capitalization SecuritiesRisk – Securities of small- and medium-capitalizationcompanies can be more volatile due to various factorsincluding more limited product lines, financial andmanagement resources and market distribution channels, aswell as shorter operating histories and potentially reducedliquidity, especially during market declines, than thesecurities of larger, more established companies.

— Valuation Risk – In certain circumstances, some of theFund’s portfolio holdings may be valued on the basis offactors other than market quotations by employing the fairvalue procedures adopted by the Board of Trustees of theTrust (the “Board”). This may occur more often in times ofmarket turmoil or reduced liquidity. Portfolio holdings that arevalued using techniques other than market quotations,including “fair valued” securities, may be subject to greaterfluctuation in their valuations from one day to the next than ifmarket quotations were used. There is no assurance that theFund could sell or close out a portfolio position for the valueestablished for it at any time, and it is possible that the Fundwould incur a loss because a portfolio position is sold orclosed out at a discount to the valuation established by theFund at that time.

Baillie Gifford Asia Ex Japan Fund

Investment ObjectiveBaillie Gifford Asia Ex Japan Fund seeks capital appreciation.

Investment StrategiesThe Fund seeks to meet its objective by investing in a portfolio ofcommon stocks and other equity securities of issuers located inAsia (excluding Japan) and including the Indian subcontinent.

Under normal circumstances, the Fund will invest at least 80% ofits net assets (plus any borrowings for investment purposes) insecurities of companies located in countries represented in theMSCI All Country Asia Ex Japan Index. The MSCI All CountryAsia Ex Japan Index includes large-cap, mid-cap, and small-capissuers from a variety of countries including China, Hong Kong,India, Indonesia, Malaysia, the Philippines, Singapore, SouthKorea, Taiwan, and Thailand. The economies of many of thesecountries are considered emerging market economies, and somemay be considered frontier markets. The Fund will invest in equitysecurities either directly or indirectly, such as through depositaryreceipts, and may invest in preferred stocks, convertiblesecurities and warrants. The Fund is not constrained with respectto market capitalization and may participate in IPOs and insecurities offerings that are not registered in the U.S. Undernormal circumstances, the Fund will aim to remain fully investedin equities, holding cash and cash equivalents primarily duringperiods of investment reallocation, or in connection withpurchases of or redemptions from the Fund.

The portfolio managers select companies without beingconstrained by the MSCI All Country Asia Ex Japan benchmark.The portfolio managers focus on company research and the long-term outlook of companies and industries. Ideas can come froma wide variety of sources, including, but not limited to, researchtrips, company meetings, and relationships with industry thoughtleaders and academic institutions. Stock ideas are normallyresearched to assess a range of factors, including: long-termgrowth potential, geographic and industry positioning, competitiveadvantage, management, financial strength and valuation. Theintended outcome is a diversified portfolio of between 50 and 100growth companies with the potential to outperform thebenchmark over the long term. The Fund aims to hold securitiesfor relatively long periods, which results in relatively low portfolioturnover and is in line with the Fund’s long-term investmentoutlook.

The portfolio managers employ a bottom-up stock-pickingapproach that seeks to make long-term investments in well-managed businesses with genuine and sustainable competitiveadvantages. The portfolio managers seek to identify companiesthat are likely to generate above average growth in earnings andcash flows, based on fundamental research. The Manager’sfundamental research process focuses on: (i) the opportunity foran issuer to deliver superior returns; (ii) the ability of the issuer toexecute on that opportunity; and (iii) the current market valuationof the security.

The portfolio managers may sell a holding if they determine therehas been a material deterioration in the investment case or asappropriate to make other investments or meet redemptions.

The Fund may invest without limitation in securities quoted ordenominated in currencies other than the U.S. dollar and mayhold such currencies. The Fund does not expect to engage incurrency hedging and thus expects to be fully exposed tocurrency fluctuations relative to the U.S. dollar. In response toadverse market, economic, political or other conditions, the Fundmay deviate from its investment policies by taking temporarydefensive positions with some or all of its assets in high qualityincome securities, cash or cash equivalents. As a result, duringsuch conditions, the Fund may not achieve its investmentobjective.

Investment ObjectiveBaillie Gifford China A Shares Growth Fund seeks capitalappreciation.

Investment StrategiesThe Fund seeks to meet its objective by investing in a portfolio ofcommon stocks and other equity securities of issuers located inChina.

Under normal circumstances, the Fund will invest at least 80% ofits net assets (plus any borrowings for investment purposes) inChina A Shares. China A Shares are common stocks and otherequity securities of issuers located in China that are listed ortraded on the Shanghai Stock Exchange, the Shenzhen StockExchange, or any other stock exchange in China and which arequoted in RMB.

The Stock Connect programs are securities trading and clearinglink programs that enable international investors to invest inChina A Shares, providing a direct investment channel to tradeeligible securities on the Shanghai Stock Exchange and theShenzhen Stock Exchange. In the future, additional Chinesestock exchanges may establish structures similar to the currentStock Connect programs. Trading under the Stock Connectprograms is subject to an aggregate daily quota, which limits themaximum net buy value of cross-boundary trades under each ofthe Stock Connect programs each day. The Stock Connectprograms are also subject to various other restrictions which mayconstrain the Fund’s ability to invest in a particular company at aparticular time, such as limits on when markets are open andtrades processed and additional regulations and listing rulesimposed by China and the Shanghai and Shenzhen exchanges.Additionally, foreign investors in aggregate are limited to owningno more than 30% of the total issued shares of any listedcompany, including those participating in the Stock Connectprograms.

The portfolio managers employ anadditional due diligence process for Chinese companies in lightof the comparative immaturity of the Chinese capital markets andthe status of China as an emerging market economy.

The portfolio managers seek to identify exceptional growthcompanies in China and hold them for long enough that theadvantages of their business models and the strength of theircorporate cultures become dominant drivers of their stock price.The intended outcome is a non-diversified portfolio of between25 and 40 growth companies with the potential to outperform thebenchmark over the long term. The Fund intends to operate as anon-diversified fund, which means that it may invest a relativelylarge percentage of its assets in a small number of issuers,industries, or sectors. The Fund aims to hold securities for longperiods (typically 5-10 years), which is expected to result in arelatively low portfolio turnover and is in line with the Fund’s long-term investment outlook.

The Fund will invest in equity securities either directly orindirectly, such as through depositary receipts or participatorynotes and may invest in preferred stocks, convertible securitiesand warrants.

The Fund expects to directly access China A Shares through theStock Connect programs. The Stock Connect programs aresecurities trading and clearing link programs that enableinternational investors to invest in China A Shares, providing adirect investment channel to trade eligible securities on theShanghai Stock Exchange and the Shenzhen Stock Exchange. Inthe future, additional Chinese stock exchanges may establishstructures similar to the current Stock Connect programs. Tradingunder the Stock Connect programs is subject to an aggregatedaily quota, which limits the maximum net buy value of cross-boundary trades under each of the Stock Connect programseach day. The daily quota is not specific to any one particularinvestor. The Stock Connect programs are also subject to variousother restrictions which may constrain the Fund’s ability to investin a particular company at a particular time, such as limits onwhen markets are open and trades processed and additionalregulations and listing rules imposed by China and the Shanghaiand Shenzhen exchanges. Additionally, foreign investors inaggregate are limited to owning no more than 30% of the totalissued shares of any listed company, including thoseparticipating in the Stock Connect programs.

The Fund may in the future also directly access securities ofcompanies through the QFI program or other means of accesswhich may become available in the future. The foregoingchannels are intended to allow the Fund to invest in securities ofcompanies listed on exchanges located in China directly. Inaddition, the Fund may invest in equity securities indirectly, suchas through depositary receipts or ETFs, especially duringextended closures of the Chinese markets.

The portfolio managers employ a bottom-up stock-pickingapproach that seeks to make long-term investments in

well-managed businesses with genuine and sustainablecompetitive advantages. The portfolio managers seek to identifycompanies that are likely to generate above-average growth inearnings and cash flows, based on fundamental research.

The portfolio managers will principally select companies withoutbeing constrained by the Fund’s benchmark, the MSCI China AllShares Index and, therefore, there may be listings in thebenchmark that are not included in the Fund’s portfolio andholdings in the Fund’s portfolio that are not included in thebenchmark. The portfolio managers focus on company researchand the long-term outlook of companies and industries. Ideascan come from a wide variety of sources, including, but notlimited to, research trips, company meetings, and relationshipswith industry thought leaders and academic institutions. Stockideas normally will be researched to assess a range of factors,including: long-term growth potential, geographic and industrypositioning, competitive advantage, management, financialstrength, and valuation. As part of their bottom-up stock-pickingapproach, the portfolio managers employ an additional duediligence process for Chinese companies. In light of thecomparative immaturity of the Chinese capital markets and thestatus of China as an emerging market economy, the portfoliomanagers complete a due diligence checklist for each Chinesecompany, which covers topics such as management andownership and business financials. If the portfolio managersidentify any areas of further interest during this due diligencereview, the portfolio managers may commission additionalresearch from third-party specialists.

The portfolio managers seek to identify exciting growthcompanies in China across a broad range of sectors with thepotential to achieve the Fund’s investment objective. Theintended outcome is a non-diversified portfolio of between 40 and80 growth companies with the potential to outperform thebenchmark over the long term. The Fund intends to operate as anon-diversified fund, which means that it may invest a relativelylarge percentage of its assets in a small number of issuers,industries, or sectors. The Fund aims to hold securities for longperiods (typically 5+ years), which is expected to result in arelatively low portfolio turnover and be in line with the Fund’slong-term investment outlook. It is expected that the Fund willhold large positions, over 5%, in a small number of companiesconsistent with the Fund operating as a non-diversified fund.

The portfolio managers may sell a holding if they determine therehas been a material deterioration in the investment case or asappropriate to make other investments or meet redemptions.

The Fund may invest without limitation in securities quoted ordenominated in currencies other than the U.S. dollar and mayhold such currencies. The Fund does not expect to engage incurrency hedging and thus expects to be fully exposed tocurrency fluctuations relative to the U.S. dollar.

Baillie Gifford Developed EAFE All Cap Fund

Investment ObjectiveBaillie Gifford Developed EAFE All Cap Fund seeks capitalappreciation.

Investment StrategiesThe Fund seeks to meet its objective by investing in a portfolio ofcommon stocks and other equity securities of issuers located innon-U.S. countries with developed markets.

Under normal circumstances, the Fund invests at least 80% of itsnet assets (plus any borrowings for investment purposes) incommon stocks and other equity securities of companies whoseprincipal activities are in developed markets in Europe,Australasia and/or the Far East. The Fund invests in equitysecurities either directly or indirectly, such as through depositaryreceipts, and may invest in preferred stocks, convertiblesecurities and warrants. The Fund is not constrained with respectto market capitalization and may participate in IPOs and insecurities offerings that are not registered in the U.S. In selectingcompanies for investment, the portfolio managers focus onissuers in developed markets, but in some circumstances maygain exposure to emerging markets. Under normalcircumstances, the Fund aims to remain fully invested in equities,holding cash and cash equivalents primarily during periods ofinvestment reallocation, or in connection with purchases of orredemptions from the Fund.

The portfolio managers retain flexibility to invest without beingconstrained by the MSCI EAFE benchmark and, therefore, theremay be listings in the benchmark that are not included in theFund’s portfolio and holdings in the Fund’s portfolio that are notincluded in the benchmark. The portfolio managers focus oncompany research and the long-term outlook of companies andindustries. Ideas can come from a wide variety of sources,including, but not limited to, research trips, company meetings,and relationships with industry thought leaders and academicinstitutions. Stock ideas are normally researched to assess arange of factors that may include: long-term growth potential,geographic and industry positioning, competitive advantage,management, financial strength and valuation. The intendedoutcome is a diversified portfolio of between 50 and 90 growthcompanies with the potential to outperform the benchmark overthe long term. The process can result in significant exposure to asingle country or a small number of countries, which in recentperiods has included Japan. The Fund aims to hold securities forlong periods (typically 5+ years), which results in relatively lowportfolio turnover and is in line with the Fund’s long-terminvestment outlook.

The portfolio managers employ a bottom-up stock-pickingapproach that seeks to make long-term investments in well-managed businesses with genuine and sustainable competitiveadvantages. The portfolio managers seek to identify companiesthat are likely to generate above average growth in earnings andcash flows, based on fundamental research. When evaluating anissuer, the Manager considers questions, such as the following:(i) Will the issuer have significantly larger earnings and cashflows in five years?; (ii) Is the issuer’s management sensiblyguarding the shareholders’ capital?; (iii) Why is the expectedgrowth not reflected in the security’s current share price?; and(iv) What would make the Manager sell?

The Fund is managed by the same portfolio managers as BaillieGifford EAFE Plus All Cap Fund. The Fund invests in a mannersimilar to that of Baillie Gifford EAFE Plus All Cap Fund, exceptthat the Fund does not include among its principal investmentstrategies the investment in emerging markets.

The portfolio managers may sell a holding if they determine therehas been a material deterioration in the investment case or asappropriate to make other investments or meet redemptions.

The Fund may invest without limitation in securities quoted ordenominated in currencies other than the U.S. dollar and mayhold such currencies. The Fund does not expect to engage incurrency hedging and thus expects to be fully exposed tocurrency fluctuations relative to the U.S. dollar. In response toadverse market, economic, political or other conditions, the Fundmay deviate from its investment policies by taking temporarydefensive positions with some or all of its assets in high qualityincome securities, cash or cash equivalents.

— the capital structure, articles of incorporation, and thecountry or countries of incorporation and listing;

— the treatment and protection of minority shareholders;

— the support of and commitment to sustainable businesspractices;

— the alignment of interests between management, strategicshareholders and other investors;

In incorporating stewardship in its investment process, theportfolio management team also performs an ESG analysis oncompanies considered for inclusion in the Fund’s portfolio. Thisanalysis is supported by bespoke research conducted byanalysts from members of the Manager’s dedicated Governanceand Sustainability team using a range of different informationsources including corporate reports, monitoring services andspecialist ESG data providers. This bespoke work is thenaugmented and compared to external data sources, including theUnited Nations Global Compact for business, which cover areasincluding human rights, labor rights, environmental safeguardsand combating bribery and corruption (collectively, the “Third-Party Reports”). The ESG analysis is reviewed by the portfoliomanagers as part of the discussion of the broader investmentcase for each current and potential portfolio holding. TheManager considers a company’s supportive contributions to ESGmatters as a positive factor when making investment decisions.The portfolio managers will also seek to identify any Fundholdings where the Manager may have the ability to influencecompany management with respect to stewardship or ESGissues and may attempt to proactively engage management ofthe companies on the issues identified.

In addition to the ESG analysis described above, the Managerincorporates multiple qualitative and quantitative screens to avoidinvestments in issuers engaged in certain activities and businesslines that the Manager believes are environmentally or sociallyharmful, as well as to avoid issuers failing to take sufficientactions the Manager believes to be environmentally or sociallybeneficial. For example, the Fund will not invest in any companythat derives more than 10 percent of its annual revenues fromone or more of the following activities: (a) the production or saleof tobacco, armaments or alcohol; (b) gambling or adultentertainment related activities; and (c) fossil fuel extraction.

The Manager generally will not invest in a company which doesnot pass the Manager’s qualitative screens and assessments,including those based on the company’s performance withrespect to principles laid out in the Third-Party Reports selectedby the portfolio management team. If the Manager becomesaware that a current holding fails to pass an investment screen,the Manager will seek to dispose of such holding in an orderlymanner over a reasonable period of time, taking into account theliquidity of the holding and other market factors. The portfoliomanagers may sell a holding if they determine there has been amaterial deterioration in the investment case or the Manager’sESG assessment of the company or as appropriate to makeother investments or meet redemptions.

The Fund may invest without limitation in securities quoted ordenominated in currencies other than the U.S. dollar and mayhold such currencies. The Fund does not expect to engage incurrency hedging and thus expects to be fully exposed tocurrency fluctuations relative to the U.S. dollar. In response toadverse market, economic, political or other conditions, the Fundmay deviate from its investment policies by taking temporarydefensive positions with some or all of its assets in high qualityincome securities, cash or cash equivalents. As a result, duringsuch conditions, the Fund may not achieve its investmentobjective.

The portfolio managers principally select companies withoutbeing constrained by the MSCI ACWI (ex U.S.) benchmark and,therefore, there may be listings in the benchmark that are notincluded in the Fund’s portfolio and holdings in the Fund’sportfolio that are not included in the benchmark. The portfoliomanagers focus on company research and the long-term outlookof companies and industries. Ideas can come from a wide varietyof sources, including, but not limited to, research trips, companymeetings, and relationships with industry thought leaders andacademic institutions. Stock ideas are normally researched toassess a range of factors, including: long-term growth potential,geographic and industry positioning, competitive advantage,management, financial strength and valuation. The intendedoutcome is a diversified portfolio of between 70 and 110 growthcompanies with the potential to outperform the benchmark overthe long term. The process can result in significant exposure to asingle country or a small number of countries, which in recentperiods have included Japan and China. The Fund expects toinvest in Chinese companies, among other means, through ChinaA shares, which are common stocks and other equity securitiesthat are listed or traded on a Chinese stock exchange and whichare quoted in renminbi. The Fund aims to hold securities for longperiods (typically 5 years), which results in relatively low portfolioturnover and is in line with the Fund’s long-term investmentoutlook.

The portfolio managers employ a bottom-up stock-pickingapproach that seeks to make long-term investments in well-managed businesses with genuine and sustainable competitiveadvantages. The portfolio managers seek to identify companiesthat are likely to generate above average growth in earnings andcash flows, based on fundamental research. The Manager’s

fundamental research process focuses on: (i) the opportunity foran issuer to deliver superior returns; (ii) the ability of the issuer toexecute on that opportunity; and (iii) the current market valuationof the issuer.

The portfolio managers may sell a holding if they determine therehas been a material deterioration in the investment case or asappropriate to make other investments or meet redemptions.

The Fund may invest without limitation in securities quoted ordenominated in currencies other than the U.S. dollar and mayhold such currencies. The Fund does not expect to engage incurrency hedging and thus expects to be fully exposed tocurrency fluctuations relative to the U.S. dollar. In response toadverse market, economic, political or other conditions, the Fundmay deviate from its investment policies by taking temporarydefensive positions with some or all of its assets in high qualityincome securities, cash or cash equivalents. As a result, duringsuch conditions, the Fund may not achieve its investmentobjective.

The inclusion of “alpha” in the Fund’s name does not reflect anygreater or lesser correlation with or reference to any benchmarkindex’s constituents or returns than for other series of the Trustwithout “alpha” in their names.

Investment ObjectiveBaillie Gifford International Growth Fund seeks capitalappreciation.

Investment StrategiesThe Fund seeks to meet its objective by investing in a diversified,international portfolio of common stocks and other equitysecurities of issuers located in countries of developed andemerging markets.

The Fund invests predominantly in securities issued bycompanies located in countries outside the U.S., including arange of developed and emerging market countries. The Fundmay, however, invest up to 10% of its net assets in commonstocks and other equities of companies located in the U.S. Undernormal circumstances, the Fund invests in securities of issuerslocated in at least three countries outside the U.S. and typicallymaintains substantial exposure to emerging markets. The Fundinvests in equity securities either directly or indirectly, such asthrough depositary receipts, and may invest in preferred stocks,convertible securities and warrants. The Fund is not constrainedwith respect to market capitalization and may participate in IPOsand in securities offerings that are not registered in the U.S. Inselecting companies for investment, the portfolio managersgenerally consider issuers in both developed and emergingmarkets. Under normal circumstances, the Fund aims to remainfully invested in equities, holding cash and cash equivalentsprimarily during periods of investment reallocation, or inconnection with purchases of or redemptions from the Fund.

The portfolio managers select companies without beingconstrained by the MSCI ACWI ex U.S. benchmark and,therefore, there may be listings in the benchmark that are notincluded in the Fund’s portfolio and holdings in the Fund’sportfolio that are not included in the benchmark.

The Fund expects tohave considerable exposure to Chinese companies, includingthrough China A shares, which are common stocks and otherequity securities that are listed or traded on a Chinese stockexchange and which are quoted in renminbi. The Fund aims tohold securities for long periods (typically 5 years), which resultsin relatively low portfolio turnover and is in line with the Fund’slong-term investment outlook. Because the Fund aims to holdsecurities for long periods, the Fund does not expect to activelyreduce its holdings of shares of particular issuers (other than inresponse to purchase and redemption requests) even if marketmovements cause the Fund to operate as a non-diversifiedcompany for an extended period of time.

Baillie Gifford International Smaller Companies Fund

Investment ObjectiveBaillie Gifford International Smaller Companies Fund seekscapital appreciation.

Investment StrategiesThe Fund seeks to meet its objective by investing in aninternational portfolio of common stocks of smaller companieslocated in countries of developed and emerging markets.

When selecting companies for initial inclusion in the Fund’sportfolio, the Fund seeks to invest in companies with a marketcapitalization in the region of $2 billion or lower. The Fund maycontinue to hold, and may increase its investment in, portfoliocompanies whose market capitalization subsequently increases.The Fund typically will not seek to increase the percentage of itsportfolio invested in any company whose market capitalization isin excess of $5 billion. However, in cases where the marketcapitalization of a portfolio company has increased above$5 billion, the Fund may continue to purchase additional sharesof that company so long as the percentage of the Fund’sportfolio represented by that company will be the same as orlower than it was before the company’s market capitalizationincreased above $5 billion. The Fund expects over time to have asubstantial portion of its portfolio invested in companies with amarket capitalization in excess of $2 billion. However, undernormal circumstances, the Fund invests at least 80% of its netassets (plus any borrowings for investment purposes) insecurities of smaller companies. The Manager currently definesa “smaller company” as a company with a market capitalizationthat does not exceed $10 billion.

In addition, under normal circumstances, the Fund will investprimarily in companies located outside the U.S. The Fundordinarily invests in securities of issuers located in at leastthree countries outside the U.S., although the Fund may focus itsinvestments in a small number of countries or regions. The Fundinvests in equity securities either directly or indirectly, such asthrough depositary receipts, and may invest in preferred stocks,convertible securities and warrants. The Fund may participate inIPOs and in securities offerings that are not registered in the U.S.In some emerging markets, the Fund may invest in companiesthat qualify as smaller companies but still are among the largestin that market. Under normal circumstances, the Fund aims toremain fully invested in equities, holding cash and cashequivalents primarily during periods of investment reallocation, orin connection with purchases of or redemptions from the Fund.

The portfolio managers may sell a holding if they determine therehas been a material deterioration in the investment case, asappropriate to make other investments or meet redemptions, orwhen the issuing company’s market capitalization has increasedso substantially that the portfolio managers no longer consider itappropriate for the Fund’s portfolio.

The portfolio managers employ a bottom-up stock-pickingapproach that seeks to make long-term investments in well-managed businesses with genuine and sustainable competitiveadvantages. The portfolio managers principally select companieswithout being constrained by the Fund’s benchmark, the MSCIACWI ex-USA Small Cap Index, and, therefore, there may belistings in the benchmark that are not included in the Fund’s

portfolio and holdings in the Fund’s portfolio that are not includedin the benchmark. The portfolio managers focus on companyresearch and the long-term outlook of companies. Ideas cancome from a wide variety of sources, including, but not limited to,research trips, company meetings, and relationships with industrythought leaders and academic institutions. Stock ideas arenormally researched to assess a range of factors, including:long-term growth potential, geographic and industry positioning,competitive advantage, management, financial strength andvaluation. The intended outcome is a diversified portfolio ofbetween 75 and 175 growth companies with the potential tooutperform the benchmark over the long term. The process canresult in significant exposure to a single country or a smallnumber of countries, which in recent periods has included Japan.The Fund aims to hold securities for long periods (typically5 years), which results in relatively low portfolio turnover and is inline with the Fund’s long-term investment outlook.

Under normal circumstances, the Fund invests at least 80% of itsnet assets (plus any borrowings for investment purposes) inequity securities. The Fund invests predominantly in securitiesissued by companies located in countries represented in theMSCI ACWI Index, cash and cash equivalents.

The Fund invests in equity securities either directly or indirectly,such as through depositary receipts, and may invest in preferredstocks, convertible securities and warrants. The Fund is notconstrained with respect to market capitalization and mayparticipate in IPOs and in securities offerings that are notregistered in the U.S. Under normal circumstances, the Fundaims to remain fully invested in equities, holding cash and cashequivalents primarily during periods of investment reallocation, orin connection with purchases of or redemptions from the Fund.The portfolio managers select companies without beingconstrained by the MSCI ACWI benchmark and, therefore, theremay be listings in the benchmark that are not included in theFund’s portfolio and holdings in the Fund’s portfolio that are notincluded in the benchmark. The portfolio managers focus oncompany research and the long-term outlook of companies andindustries. Ideas can come from a wide variety of sources,including, but not limited to, research trips, company meetings,and relationships with industry thought leaders and academicinstitutions. Stock ideas are normally researched to assess arange of factors, including: long-term growth potential,geographic and industry positioning, competitive advantage,management, financial strength and valuation. The intendedoutcome is a portfolio of between 25 and 50 growth companieswhich the portfolio managers consider to have core ambitions ofdelivering a positive change and with the potential to outperformthe benchmark over the long term. The process can result insignificant exposure to a single country or a small number ofcountries, which in recent periods has included Japan. The Fundis a non-diversified fund, which means that it may invest arelatively large percentage of its assets in a small number ofissuers, industries or sectors. The Fund aims to hold securitiesfor long periods (typically 5-10 years), which results in relativelylow portfolio turnover and is in line with the Fund’s long-terminvestment outlook.

The portfolio managers consider the investment case and thepotential for positive change in tandem. On the investment sideof the process, the portfolio managers employ a bottom-up stock-picking approach that seeks to make long-term investments inwell-managed businesses with genuine and sustainablecompetitive advantages. The portfolio managers seek to identifycompanies that are likely to generate above average growth in

earnings and cash flows, based on fundamental research. TheManager’s fundamental research process focuses on the growthpotential of a company and its competitive advantages.

In seeking to invest in businesses that deliver positive socialimpact, the portfolio managers and Governance & SustainabilityAnalysts who form the Positive Change Portfolio ConstructionGroup focus on the ability of a company to deliver positivechange in at least one of the following four areas:

— Social Inclusion and Education. Companies that(i) contribute to a more inclusive society through businesspractices, products or services, or (ii) are improving thequality or accessibility of education.

— Healthcare. Companies that are actively improving quality oflife in developed and developing countries.

— Environment. Companies committed to improving resourceefficiency and reducing the environmental impact of society’seconomic activities.

— Base of the Pyramid. Companies that are addressing thebasic and aspirational needs of the world’s poorestpopulations.

In order to assess positive change in these areas, the Managerwill monitor the progress of each issuer using metrics and/ormilestones designed by the Manager. With respect to each area,the Manager pursues an active, positive approach; investmentdecisions are generally not made on the basis of negative“screening” of companies viewed as socially irresponsible.

The portfolio managers may sell a holding if they determine therehas been a material deterioration in the investment case or in theissuer’s potential for delivering positive change, or as appropriateto make other investments or meet redemptions.

The Fund may invest without limitation in securities quoted ordenominated in currencies other than the U.S. dollar and mayhold such currencies. The Fund does not expect to engage incurrency hedging and thus expects to be fully exposed tocurrency fluctuations relative to the U.S. dollar. In response toadverse market, economic, political or other conditions, the Fundmay deviate from its investment policies by taking temporarydefensive positions with some or all of its assets in high qualityincome securities, cash or cash equivalents.

Baillie Gifford U.S. Discovery Fund

Investment ObjectiveBaillie Gifford U.S. Discovery Fund seeks capital appreciation.

Investment StrategiesThe Fund will seek to meet its objective by investing in a portfolioof common stocks and other equity securities of smaller, publiclytraded U.S. companies that are perceived to be innovative andentrepreneurial, such as by disrupting existing markets orcreating entirely new ones, and that have strong growth potential.

In selecting portfolio investments, the portfolio managers seek todiscover innovative and entrepreneurial companies through aprocess that involves considering, among other things, a potentialholding’s market opportunity, competitive edge, corporate culture,and scalability prospects. The inclusion of “discovery” in theFund’s name does not reflect an intent to invest in any particulartype of investment or industry.

When selecting companies for initial inclusion in the portfolio, theportfolio managers focus on publicly traded companies with amarket capitalization in the region of $10 billion or lower at thetime of initial purchase. Because the Fund will be managed inaccordance with an established model investment strategyoperated by the portfolio managers, the Fund’s portfolio isexpected to include a number of companies with marketcapitalizations of greater than $10 billion at the time the Fundcommences investment operations. These are companies thathad market capitalizations of less than $10 billion at the time ofinclusion in the model investment strategy, but which havesubsequently grown. In addition, because the Fund expects tocontinue to hold, and potentially increase its investment in,portfolio companies whose market capitalizations increasesubsequent to the initial purchase, the Fund expects over time tohave a substantial portion of its portfolio invested in companieswith a market capitalization in excess of $10 billion. Undernormal circumstances, the Fund will invest at least 80% of itsassets in securities of small- and mid-capitalization companies,which the Manager defines as companies with marketcapitalizations of $30 billion or less.

Under normal circumstances, the Fund will invest at least 80% ofits net assets (plus any borrowings for investment purposes) insecurities of issuers located in the U.S. The Fund will invest inequity securities either directly or indirectly, such as throughdepositary receipts, and may invest in preferred stocks,convertible securities and warrants. Under normal circumstances,the Fund will aim to remain fully invested in equities, holding cashand cash equivalents primarily during periods of investmentreallocation, or in connection with purchases of or redemptionsfrom the Fund.The Fund may participate in IPOs.

The portfolio managers will select companies without beingconstrained by the Fund’s Benchmark, the Russell 2500 GrowthIndex, and, therefore, there may be listings in the benchmark thatare not included in the Fund’s portfolio and holdings in the Fund’sportfolio that are not included in the benchmark. The portfoliomanagers will employ a bottom-up stock-picking approach thatseeks to make long-term investments in well-managedbusinesses with genuine and sustainable competitiveadvantages. The portfolio managers will seek to identifycompanies that are likely to generate above-average growth inearnings and cash flows, based on fundamental research. Inevaluating potential investments, the portfolio managers will

consider, among other things, the following attributes of thepotential holding:

• Market opportunity—Whether the company looks to drivechange by disrupting existing markets or creating entirelynew ones, which can potentially create growth opportunitiesover the long term.

• Competitive edge—Whether the company exhibits astrengthening competitive position and is able to innovateand meaningfully differentiate itself from peers.

• Corporate culture—The extent to which the company’scorporate culture is aligned with the strengths of thecompany, incentives are structured to encourage innovationin changing conditions, and the company’s management hasa clear sense of purpose and vision.

• Scalability—Whether the company’s business models areinherently scalable, and whether the company’s returns areable to increase over time.

The portfolio managers focus on company research and the long-term outlook of companies and industries. Ideas can come froma wide variety of sources, including, but not limited to, researchtrips, company meetings, and relationships with industry thoughtleaders and academic institutions. Stock ideas are normallyresearched to assess a range of factors, including: long-termgrowth potential, geographic and industry positioning, competitiveadvantage, management, financial strength and valuation. Theintended outcome is a non-diversified portfolio of between 40 and75 growth companies with the potential to outperform thebenchmark over the long term. While the Fund may take smallerinitial positions in a range of companies, the portfolio managersdo not intend to limit their ability to continue to hold or augmentpositions in successful companies, which can naturally result,over time, in a significant percentage of the Fund’s portfolio beingattributable to a small number of companies. For this and otherreasons, the Fund intends to operate as a non-diversified fund,which means that it may invest a relatively large percentage of itsassets in a small number of issuers, industries, or sectors. TheFund aims to hold securities for long periods (typically 5-10years), which is expected to result in relatively low portfolioturnover and be in line with the Fund’s long-term investmentoutlook.

The portfolio managers may sell a holding if they determine therehas been a material deterioration in the investment case or asappropriate to make other investments or meet redemptions.Subject to adhering to the Fund’s investment policies, theportfolio managers will not look to sell the Fund’s holdings basedon market capitalization alone. In response to adverse market,economic, political or other conditions, the Fund may deviatefrom its investment policies by taking temporary defensivepositions with some or all of its assets in high quality incomesecurities, cash or cash equivalents. As a result, during suchconditions, the Fund may not achieve its investment objective.

Baillie Gifford U.S. Equity Growth Fund

Investment ObjectiveBaillie Gifford U.S. Equity Growth Fund seeks capitalappreciation.

Investment StrategiesThe Fund seeks to meet its objective by investing in a portfolio ofequities, which include common stock and other equity securities,of issuers located in the U.S.

The portfolio managers seek to identify exceptional growthbusinesses in the U.S. and to own them for long enough that theadvantages of their business models and the strength of theircultures support positive relative performance over the long term.

Under normal circumstances, the Fund invests at least 80% of itsnet assets (plus any borrowings for investment purposes) incommon stocks and other equity securities of companies whoseprincipal activities are in the U.S. The Fund invests in equitysecurities either directly or indirectly, such as through depositaryreceipts, and may invest in preferred stocks, convertiblesecurities and warrants. The Fund typically invests primarily inissuers with a market capitalization of more than $1.5 billion atthe time of purchase and may participate in IPOs. Under normalcircumstances, the Fund aims to remain fully invested in equities,holding cash and cash equivalents primarily during periods ofinvestment reallocation, or in connection with purchases of orredemptions from the Fund.

The portfolio managers employ a bottom-up stock-pickingapproach that seeks to make long-term investments in well-managed businesses with genuine and sustainable competitiveadvantages. The portfolio managers select companies withoutbeing constrained by a benchmark and, therefore, there may belistings in the benchmark that are not included in the Fund’sportfolio and holdings in the Fund’s portfolio that are not includedin the benchmark. The portfolio managers generally invest in aportfolio of between 30 and 50 growth companies. The portfoliomanagers focus on company research and the long-term outlookof companies and industries. Ideas can come from a wide varietyof sources, including, but not limited to, research trips, companymeetings, and relationships with industry thought leaders andacademic institutions. Stock ideas are normally researched toassess a range of factors, including: long-term growth potential,geographic and industry positioning, competitive advantage,management, financial strength and valuation. The Fund is anon-diversified fund, which means that it may invest a relativelylarge percentage of its assets in a small number of issuers,industries or sectors. The Fund aims to hold securities for longperiods (typically 5-10 years), which results in relatively lowportfolio turnover and is in line with the Fund’s long-terminvestment outlook.

The portfolio managers believe a long-term investment horizoncan allow the Fund to harness the asymmetry inherent in equitymarkets that allows successful investments to outpace losses insimilarly sized positions that fail to thrive.

The portfolio managers may sell a holding if they determine therehas been a material deterioration in the investment case or asappropriate to make other investments or meet redemptions.

In response to adverse market, economic, political or otherconditions, the Fund may deviate from its investment policies bytaking temporary defensive positions with some or all of itsassets in high quality income securities, cash or cashequivalents. As a result, during such conditions, the Fund maynot achieve its investment objective.

Baillie Gifford Funds – Prospectus

Selected Investment Techniques and TopicsIn addition to the principal investment strategies discussed above,the Funds may engage in certain non-principal investmentstrategies. Additional context and details regarding both the Funds’principal investment strategies and the Funds’ non-principalinvestment strategies are provided below.

Active and Frequent TradingThe Funds generally will not engage in active and frequenttrading of portfolio securities as part of their ordinary-courseefforts to achieve their principal investment strategies. However,unusual market conditions may trigger increased trading and/orportfolio turnover for a Fund to the extent the relevant investmentteam deems such actions necessary or appropriate. A higherportfolio turnover rate may indicate higher transaction costs andmay result in higher taxes when Fund shares are held in ataxable account. These transaction costs affect the Fund’sperformance.

“Alpha” FundsThe inclusion of the word “Alpha” in the name of certain Funds isnot meant to suggest a specific investment style or that a Fundtargets a specific return over and above its benchmark index. Norshould the word “Alpha” be interpreted as claiming any higherdegree of active management than any other Fund.

Capitalization Criteria and Investment LimitationsUnless otherwise stated, all market capitalization criteria andpercentage limitations on Fund investments listed in thisProspectus will apply at the time of investment. A Fund would notviolate these limitations unless an excess or deficiency occurs orexists immediately after and as a result of an investment.

References to assets in the percentage limitations on the Funds’investments refer to total assets, unless otherwise indicated.

Unless otherwise stated, when a Fund is described as investingin a particular type of security or other instrument, the Fund maymake such investments directly or indirectly. Indirect exposuremay be achieved through a combination of multiple instrumentsor through a combination of one or more investment instrumentsand cash or cash equivalents. Indirect investments may includedepositary receipts, derivatives (based on either notional ormark-to-market value depending on the instrument andcircumstances), placement warrants or other structured products.Indirect exposure may also be gained through investments inoperating companies and pooled vehicles such as mutual funds,exchange traded funds (“ETFs”), private funds, and non-U.S.investment vehicles. Because the Funds are subject to variousregulatory requirements and limitations, a Fund’s ability to obtaindirect exposure to certain asset classes and investments may beprevented or restricted.

Cash BalancesAlthough each Fund will aim to remain fully invested in equities,each Fund may hold uninvested cash balances at the Fund’scustodian or invest in cash equivalent securities, such as moneymarket funds, in order to facilitate daily portfolio operations and totake temporary defensive positions.

Considerations Related to Large ShareholdersTo the extent that a significant portion of a Fund’s shares are heldby a limited number of shareholders or their affiliates, there is arisk that the subscription and redemption activities of theseshareholders with regard to Fund shares could disrupt such Fund’sinvestment strategies, which could have adverse consequences forthe Fund and other shareholders. Such subscriptions could causethe Fund to maintain larger-than-expected cash positions pendingacquisition of investments. A redemption by a large shareholdercould require the Fund to sell investments, including atinopportune times, and could result in the Fund recognizingsignificant capital gains, including short-term capital gains, thatwould be distributed to shareholders in order for the Fund to meetthe requirements for qualification as a regulated investmentcompany and avoid a Fund-level tax. In addition, institutionalseparate accounts managed by the Manager may invest in a Fundand, therefore, the Manager at times may have discretionaryauthority over redemption decisions by a significant portion of theinvestor base holding shares of a Fund. In such instances, theManager’s decision to make changes to or rebalance itsclient’s allocations in the separate accounts may impact theFund’s performance.

CPO ExemptionThe Manager is registered as a commodity pool operator(“CPO”) with the Commodity Futures Trading Commission(“CFTC”) and is a member of the National Futures Association(the “NFA”). However, the Manager has filed with the NFA anotice with respect to the Funds claiming an exclusion from thedefinition of the term CPO under the Commodity Exchange Act,as amended, and the rules of the CFTC promulgated thereunder.As a result, the Manager, as adviser to the Funds, is not currentlysubject to registration or regulation as a CPO with respect to theFunds. However, if in the future a Fund no longer meets themarketing or de minimis trading qualifications for this exclusion,the Manager would withdraw its notice with respect to the Fundclaiming exclusion from the definition of a CPO, and the Manager,as adviser to such Fund, would be subject to registration andregulation as a CPO with respect to such Fund.

Currency HedgingThe Funds have not historically used, but may in the future use,various investment products to hedge the risks to the Funds fromexposure to local currency movements. These products includecurrency forward contracts and options thereon, and options and“spot” transactions directly in foreign currencies.

New financial products and risk management techniquescontinue to be developed and the Funds may use these newinvestments and techniques to the extent they are consistent withthe Funds’ investment objectives and strategies.

Emerging MarketsCertain Funds may invest in issuers located in emerging markets.The Funds consider emerging markets countries to be comprisedof those that are not categorized by MSCI as developed markets,excluding frontier markets.

Frontier MarketsCertain Funds may invest in issuers located in frontier markets.The Funds consider frontier markets countries to be comprised ofthose that the Manager considers to be more developed than the

least developed countries but less developed than emergingmarket countries. Frontier markets include, among others,Croatia, Estonia, Lithuania, Kazakhstan, Romania, Serbia,Slovenia, Kenya, Mauritius, Morocco, Nigeria, Tunisia, Bahrain,Jordan, Kuwait, Lebanon, Oman, Bangladesh, Sri Lankaand Vietnam.

Growth CompaniesEach Fund may invest in growth companies. When assessingwhether a company is “growth,” a Fund considers a range offactors, including, but not limited to, the ability of the company togrow earnings faster than the market expects.

Illiquid SecuritiesA Fund may not purchase or otherwise acquire any illiquidsecurities if, immediately after the acquisition, the value of illiquidsecurities held by the Fund would exceed 15% of the Fund’s netassets. The term “illiquid securities” for this purpose meanssecurities that a Fund reasonably expects cannot be sold ordisposed of in current market conditions in seven calendar daysor less without the sale or disposition significantly changing themarket value of the securities.

Illiquid securities may include those securities whose dispositionis restricted by securities laws, such as Rule 144A or privateplacement securities.

If any Fund determines at any time that it owns illiquid securitiesin excess of 15% of its net assets, it will cease to undertake newcommitments to acquire illiquid securities until its holdings nolonger exceed this 15% limit, report the occurrence in compliancewith relevant requirements under the Investment CompanyAct of 1940, as amended (the “1940 Act”), and, depending oncircumstances, may take additional steps to reduce its holdingsof illiquid securities.

Industry Classification of IssuersThe Manager shall make reasonable determinations as to theappropriate issuer industry classification, or sector classificationof security issuers. As part of this determination, the Managermay take into account internal analysis or third party informationsuch as categories, data or methodologies from BloombergIndustry Classification Systems (BICS), Global IndustryClassification Standard (GICS) codes, Standard IndustryClassification (SIC) Codes, North American IndustryClassification System (NAICS) Codes, the FTSE/Dow JonesIndustry Classification Benchmark (ICV system) or any otherreasonable industry classification system (including systemsdeveloped by the Manager). The Manager may use informationdifferently for different industries, sectors or clients. TheManager’s determinations may differ from the determinations ofother investment professionals, or other third parties. Even wherethe Manager generally relies on a particular classification system,it may depart from that system in specific cases at its discretion.

Investing in China through the Stock Connect programs andQFI programFunds that invest in China may invest in China “A” Shares(“A Shares” or “China A Shares”). China A Shares are commonstocks and other equity securities of issuers located in China thatare listed or traded on the Shanghai Stock Exchange, theShenzhen Stock Exchange, or any other stock exchange in Chinaand which are quoted in renminbi (“RMB”). These Funds may

access China A Shares through the Shanghai-Hong Kong StockConnect program and the Shenzhen-Hong Kong Stock Connectprogram (together the “Stock Connect programs”) or throughthe Manager’s qualified foreign investor (“QFI”) license.Historically, investments in stocks, bonds, and warrants listed andtraded on a mainland Chinese stock exchange, investmentcompanies, and other financial instruments (collectively referredto as “China Securities”) approved by the China SecuritiesRegulatory Commission (“CSRC”) were limited for investment bynon-Chinese investors. The CSRC has now granted the Managera QFI license allowing the Manager to invest in China Securitiesand the Funds now have access to the Stock Connect programs.

The Stock Connect programs are securities trading and clearinglink programs that enable international investors to invest inChina A Shares. Trading under the Stock Connect programs issubject to an aggregate daily quota, which limits the maximumnet buy value of cross-boundary trades under each of the StockConnect programs each day. This is monitored by the StockExchange of Hong Kong on a real-time basis and reset everyday. If the daily quota drops to zero or is exceeded, no furtherbuy orders will be accepted for the remainder of that day(although sales of China A Shares are permitted regardless ofthe daily quota). The daily quota is not specific to any oneparticular investor. The Stock Connect programs are also subjectto various other restrictions which may constrain a Fund’s abilityto invest in a particular company at a particular time, such aslimits on when markets are open and trades processed andadditional regulations and listing rules imposed by China and theShanghai and Shenzhen exchanges.

Under the QFI program, there are certain regulatory constraintsincluding, without limitation, restrictions on the types ofinstruments available for purchase by the license holder, theability of the license holder to repatriate funds, and the structureof custodial and brokerage accounts for trading in Chinesesecurities. In particular, with respect to the QFI custodialarrangements, to the extent a Fund’s cash is commingled withthe assets of other clients of a Chinese custodian and theChinese custodian becomes insolvent, a Fund will not have anyproprietary rights to the cash deposited in the account, and aFund will become an unsecured creditor, ranking pari passu withall other unsecured creditors, of the Chinese custodian. Althoughthe relevant QFI regulations have recently been revised to relaxregulatory restrictions on the onshore capital management byQFI license holders (including removing investment quota limitand simplifying routine repatriation of investment proceeds), it isa new development and therefore subject to uncertainties as tohow well it will be implemented in practice, especially at the earlystage. For additional information regarding custody risks that maybe applicable to both the QFI and Stock Connect programs, see“Principal Investment Risks—Non-U.S. Investment Risk” belowand “Risks—Emerging Markets Risk—Custody Risk” in theStatement of Additional Information (the “SAI”).

See also “Principal Investment Risks—China Risk” below.

Investment CompaniesEach Fund may invest in other investment companies, includingETFs, to the extent permitted under the 1940 Act. The 1940 Actplaces limits on each Fund’s ability to invest in other registeredinvestment companies, though the Funds may generally investwithout limitation in unaffiliated unregistered pooled investment

vehicles, other registered investment companies advised by theManager and, in reliance on available exemptive relief, in ETFs.As a shareholder of these kinds of investment vehicles, a Fundmay indirectly bear fees which are in addition to the fees theFund pays its own service providers. To the extent permitted bylaw, the Funds may invest in collective investment vehicles thatare sponsored by, and advised by, the Manager or an affiliate ofthe Manager (an “Affiliated Vehicle”). Any fee payable to theManager or an affiliate thereof by any Affiliated Vehicle in respectof an investment by a Fund in such Affiliated Vehicle shall bereimbursed to the Fund by the Manager. Therefore, a Fund willonly bear that portion of Affiliated Vehicle expenses payable topersons or entities other than the Manager or its affiliates, andwill not be responsible for fees collected by the Manager at boththe Fund level and the Affiliated Vehicle level.

Location of IssuersA number of the Funds’ policies are determined by reference towhether an issuer is “located in” a particular country or group ofcountries, whether its “principal activities” are in certain regions,or whether the issuer is located outside the U.S. more generally.

In determining where an issuer is located for these purposes, orwhere an issuer’s principal activities are, the Manager willconsider a number of factors (together, designed to determinewhether an issuer is economically tied to a country or region),including but not limited to:

— the markets in which the issuer’s securities are principallytraded;

— where the issuer’s headquarters, principal offices oroperations are located;

— where the issuer is organized;

— the percentage of the issuer’s revenues or profits derivedfrom goods produced or sold, investments made, or servicesperformed in the relevant country;

— the Manager’s own internal analysis; and

— information provided by third party data analytics serviceproviders.

No single factor will necessarily be determinative nor must all bepresent for the Manager to determine where an issuer is located.The Manager may weight these factors differently with respect todifferent geographic policies, different countries or different seriesof the Trust.

The categorization for compliance testing purposes may differfrom how different portfolio managers, investment professionals,or third parties assign the location of individual issuers.

Portfolio HoldingsA description of the Trust’s policies and procedures with respectto the disclosure of the Funds’ portfolio securities is available inthe SAI.

Further InformationFurther information about the Funds’ investment strategies andinvestment instruments is available in the SAI.

By way of example, the Manager may consider acompany that is organized in the U.S., with itsprincipal place of business in the U.S. and whosesecurities are traded principally on a U.S.exchange to be located outside the U.S., or tohave its principal activities outside the U.S., if, forinstance, more than 50% of the company’srevenues are derived from activity outside the U.S.This may be true even if the Manager does notdetermine that the company is located in aspecific non-U.S. country.

Securities and techniques appearing in bold below but nototherwise defined below, are described in greater detail inthe SAI, under the heading “Fund Investments—InvestmentGlossary.”

Asia RiskThe economies of countries in Asia are in all stages of economicdevelopment, and investing in companies located in or withexposure to Asian countries involves certain risks andconsiderations not typically associated with investing in securitiesof U.S. issuers. The economies of many Asian countries, such asHong Kong, South Korea, and Singapore, are heavily dependenton international trade and on only a few industries or commoditiesand, as a result, can be adversely affected by trade barriers,exchange controls and other measures imposed or negotiated bythe countries with which they trade. As export-driven economies,the economies of these countries are affected by developments inthe economies and trade policies of their principal tradingpartners, which may include China, Japan, and the U.S. ManyAsian economies are also intertwined, such that the countriesmay experience recessions at the same time or respond similarlyto adverse events. Also, securities of some companies in Asia canbe less liquid than U.S. or other foreign securities, potentiallymaking it difficult for a Fund to sell such securities at a desirabletime and price.

Furthermore, many Asian economies, such as China, SouthKorea and India, have experienced rapid growth andindustrialization, and there is no assurance that their growth ratewill be maintained. Companies in Asia may be subject to riskssuch as nationalization or other forms of governmentinterference. Some Asian countries have governments withrelatively short histories, which may increase the risk of politicalinstability. Flooding, monsoons and other natural disasters alsocan significantly affect the value of investments.

Additionally, many Asian economies are considered emergingmarket economies. These countries are often characterized byundeveloped financial service sectors, high inflation, frequentcurrency fluctuations, devaluations, or restrictions, political andsocial instability, and less efficient markets. Investments inemerging Asian markets are generally subject to a greater risk ofloss than investments in developed Asian markets. For example,investments in securities of issuers located in India involveheightened risks that include, among others, political and legaluncertainty, greater government control over the economy, andgreater risk of hyperinflation, currency fluctuations, blockage ofcurrency movements, repatriation of capital invested, and thenationalization or expropriation of assets. Moreover, India hasexperienced civil unrest and hostilities with neighboring countries,including Pakistan, and has confronted separatist movements,religious clashes, and border disputes. In addition, the availabilityof financial instruments with exposure to Indian financial marketsmay be substantially limited by the restrictions on foreigninvestors. These factors, coupled with the lack of extensiveaccounting, auditing and financial reporting standards andpractices, as compared to in the U.S., may increase the riskof loss.

Investing in issuers located in Asia also exposes a Fund toadditional risks, as further described in this section under “ChinaRisk”, “Japan Risk”, “Emerging Markets Risk”, “Frontier Markets

Risk”, “Non-U.S. Investment Risk”, and “Market Disruption andGeopolitical Risk” and in the SAI under “Special Risks ofInvesting in Asian Securities” and “Special Risk Considerationsof Investing in China.”

China Risk

Special Risk Considerations of Investing in ChinaInvesting in securities of Chinese issuers, including by investingin China A Shares, involves certain risks and considerations nottypically associated with investing in securities of U.S. issuers inpart because the Chinese government exercises significantcontrol over the Chinese economy through heavy involvement ineconomic and regulatory policy. Certain risks and considerationsof investing in Chinese issuers include among others, morefrequent trading suspensions and government interventions(including by nationalization of assets), currency exchange ratefluctuations or blockages, limits on the use of brokers and onforeign ownership, different financial reporting standards, higherdependence on exports and international trade, restrictions onthe size of permissible positions in individual Chinese issuers,potential for increased trade tariffs, sanctions, embargoes andother trade limitations, greater political, economic, social, legaland tax-related uncertainty, high market volatility caused by anypotential regional territorial conflicts, social instability, or naturaldisasters, and custody risks. U.S. sanctions or other investmentrestrictions could preclude a Fund from investing in certainChinese issuers or cause a Fund to sell investments at adisadvantageous time. Changes to political and economicrelationships, including recent trade disputes and strainedinternational relations, between China and other countries andchanges to China’s socioeconomic systems may adversely affectthe Fund’s investments in China. Additionally, portions of theChinese securities markets may become rapidly andunexpectedly illiquid, as Chinese issuers have the ability tosuspend the trading of their equity securities and have exercisedthat ability in the past in response to market volatility and otherevents. If the liquidity of investments became impaired, it couldmake investments more difficult to value, limit a Fund’s ability toobtain cash to meet redemptions on a timely basis, hinder aFund’s ability to honor redemption requests within the allowabletime period, and force a Fund to sell securities at a reduced priceor under unfavorable conditions.

Stock Connect Investing RiskA Fund may directly invest in A Shares listed and traded on theShanghai Stock Exchange or Shenzhen Stock Exchange throughthe Stock Connect programs, or on such other stock exchangesin China which participate in the Stock Connect programs fromtime to time. A Fund’s investments in Stock Connect A Sharesare generally subject to Chinese securities regulations and listingrules, among other restrictions that may affect a Fund’sinvestments and returns, including daily limits on net purchasesacross the whole stock connect system and transfer restrictions.In addition, when investing through the Stock Connect programs,a Fund will not have access to the full market of China A Shares.Such investments are also subject to heightened tax andsettlement risk and the risk of price fluctuations of A Sharesduring times when the Stock Connect programs are not trading.The Stock Connect programs are relatively new programs.Further developments are likely and there can be no assurance

as to the programs’ continued existence or whether futuredevelopments regarding the programs may restrict or adverselyaffect a Fund’s investments or returns.

QFI Investing RiskThe Funds may, in the future, directly access securities ofcompanies listed on exchanges located in China through theManager’s QFI license. Investing in securities of Chinese issuersthrough the QFI program presents additional risks. Under the QFIprogram, there are certain regulatory restrictions relating to,among other things, investment scope, repatriation of funds,foreign shareholding limits, and account structure, which couldchange at any time and adversely affect a Fund’s investments.Additionally, there are ongoing uncertainties regarding howrecent changes to the QFI program will be implemented.

Cross-Exchange Trading RiskTrades do not cross between the Shanghai and Shenzhen stockexchanges and a separate broker is assigned for each exchange.If a Fund rebalances across both exchanges, the Fund musttrade out of stocks listed on one exchange with a broker andtrade into stocks on the other exchange with a separate broker.As a result, the Fund may incur additional fees.

Chinese Currency and Repatriation RiskThe Chinese government heavily regulates the domesticexchange of foreign currencies within China. Chinese lawrequires that all domestic transactions must be settled in RMB,which places significant restrictions on the remittance of foreigncurrencies and strictly regulates currency exchange from RMB.There is no assurance that there will always be sufficientamounts of RMB for a Fund to remain fully invested. Anyrestrictions on repatriation of a Fund’s portfolio investments mayhave an adverse effect on a Fund’s ability to meet redemptionrequests or achieve its investment objective.

China A Shares Tax RiskInvestments in A Shares could result in unexpected tax liabilitiesfor a Fund. Chinese law imposes withholding taxes on dividendsand interest paid to foreign investors by companies listed inChina, as well as capital gains realized by such investors, subjectto certain temporary exemptions applicable to capital gains andvalue-added tax on gains realized from investments in A Shares.Application of these rules, including as a result of revocation ofany temporary exemptions, could result in tax liabilities for aFund, which could negatively affect investment returns forshareholders. Any restrictions on repatriation could limit a Fund’sability to satisfy the distribution requirements applicable toregulated investment companies under the Internal RevenueCode of 1986, as amended (the “Code”), and a Fund may berequired to sell other investments (including when it is notadvantageous to do so) to meet such distribution requirements.If a Fund were unable to meet such distribution requirements,the Fund would be subject to U.S. federal income tax at theFund level.

Investing in issuers located in China also exposes a Fund toadditional risks, as further described in this section and under“Asia Risk”, “Emerging Markets Risk”, “Non-U.S. InvestmentRisk”, and “Market Disruption and Geopolitical Risk” and in theSAI under “Special Risks of Investing in Asian Securities” and“Special Risk Considerations of Investing in China.”

Conflicts of Interest RiskThe following does not purport to be a comprehensive list orcomplete explanation of all potential conflicts of interest whichmay affect a Fund. Any Fund may encounter circumstances, orenter into transactions, in which conflicts of interest may arise,which are not listed or discussed below.

Conflicts Relating to the Funds’ Mixed Shareholder BaseDue to the distribution strategy adopted by the Manager, eachFund expects that a significant portion of its shares will be heldby institutional investors such as private defined benefitretirement plans, city and state retirement systems, endowments,foundations, and other pooled investment vehicles, includingother mutual funds. These institutional investors will often havebroader shareholder servicing relationships with the Managerand its affiliates than other Fund shareholders and will likelyreceive information or reporting regarding their accounts that isdifferent from the regular reporting the Fund makes toshareholders as a whole. In some cases, these institutionalinvestors will have separate contractual arrangements with theManager relating to their investment in the Fund. The Managerand the Fund each maintains a code of ethics as well as variousprocedures and guidelines designed to promote equal treatmentand fairness among Fund shareholders and to prevent theinappropriate flow of material, non-public information.Nevertheless, the Manager’s relationships with the Fund’sinstitutional investor base gives rise to various conflicts ofinterest, since the Manager will sometimes have an incentive tofavor those shareholders over other shareholders in the Fund.

Furthermore, one or more of the Manager’s clients may invest inthe Fund and, therefore, the Manager at times may havediscretion to cause a significant portion of the Fund’s investorbase to redeem its investments in the Fund. Such redemptionsmay be made to make changes to or rebalance client allocations,including to the Fund, and may impact the Fund’s performance.In addition, when a significant portion of the Fund’s assets areheld by other clients of the Manager, redemptions from the Fundmay be more correlated with one another, which could have anegative impact on the Fund’s liquidity.

Conflicts Relating to Side-by-Side Management of the Funds andOther AccountsThe Manager serves as investment adviser to various clientsother than the Funds, including institutional separate accountsand other U.S. and non-U.S. pooled investment vehicles. Some ofthese clients may pursue strategies that are substantially similaror nearly identical to investment strategies pursued by a Fund.Other clients may pursue strategies that differ from a Fund’s butwhich involve investments in many of the same securities. This“side-by-side” management gives rise to various potential oractual conflicts of interest. For example, one client may beseeking to invest in (or divest from) the same securities at thesame time as a Fund. In addition, the Manager may invest onbehalf of other clients in a company’s securities issued prior toan IPO. Those client accounts may maintain their holdings,increase their holdings or sell their holdings in connection withthe company’s IPO. Since the Funds would generally invest onlyat the time of, or after, an IPO, the Manager could be subject toconflicts in connection with the Funds’ later investment in thecompany. For example, the Manager could have an incentive tohave the Funds purchase shares at the time of, or after, the IPO

Baillie Gifford Funds – Prospectus

if doing so would benefit the Manager’s other accounts. While theManager maintains procedures to mitigate such conflicts,including procedures for the fair allocation of trades among itsclients, it may have an incentive to favor some clients over others,particularly where the Manager is acting for a client accountwhose management fee depends on the performance of theaccount. No Fund currently pays a performance fee of any kind,while other accounts managed by the Manager do payperformance fees.

In addition, different client types typically have different clientservice relationships with the Manager. For example, aninstitutional separate account client whose account pursues thesame investment strategy as a Fund may receive different, more,or more timely information regarding investment performance,portfolio holdings, strategy developments and/or the Manager’sgeneral market outlook than shareholders in the Fund. Thisinformational advantage could provide an opportunity for a clientto take actions that may have a detrimental impact on the Fundand its shareholders. For example, earlier reporting of negativenews may cause a client to withdraw its investment with theManager, causing a sale of portfolio securities that furtherdepresses market prices for those securities and negativelyimpacts the net asset value of the Fund, in the event it ismanaged in parallel with that client’s account. The Managermaintains various internal guidelines, procedures and processesto mitigate the conflicts of interest that arise from these diverseclient relationships. Included among these are trade allocationpolicies designed to address potential conflicts in situationswhere two or more funds or accounts participate in investmentdecisions involving the same securities. While these guidelines,procedures and processes are designed to ensure that all theManager’s clients are treated fairly, there is no guarantee thatthey will be effective in all cases.

Conflicts Relating to Investment Personnel Holding Positions inExternal OrganizationsSubject to compliance oversight by the Manager, investmentpersonnel may hold board or other non-executive positions incompanies outside of Baillie Gifford (“External Organizations”),which could expose those individuals to material non-publicinformation (“MNPI”). Any MNPI known could be imputed to theentire Baillie Gifford organization, including the Manager, whichcould impact trading across all Baillie Gifford strategies and limitthe ability of the Manager to execute trades on behalf of theFunds. In addition to impacting a Fund’s ability to trade in theExternal Organization, the possession of MNPI could also restrictthe Manager’s ability to trade the securities of public companiesin which the External Organization also invests alongside theFund. While the Manager has implemented compliancemeasures to mitigate the impact of this risk, there is noguarantee that exposure to MNPI can be completely prevented.Because a Fund might not be able to buy or sell a company’ssecurities during times when the Manager is deemed to be inpossession of MNPI, its performance could be negativelyimpacted. In addition, where a portfolio manager of a Fund holdsan External Organization position, he or she may be restrictedfrom participating in deliberations concerning certain investmentsrelated to that External Organization.

Currency RiskIf a Fund trades in securities quoted or denominated incurrencies other than the U.S. dollar, or receives income in ortakes a long position in a non-U.S. currency, and that currencydeclines in value relative to the U.S. dollar, the return to the Fundwill be reduced. The Funds may invest without limitation insecurities quoted or denominated in currencies other than theU.S. dollar and may hold such currencies directly. The Funds donot expect to engage in currency hedging and thus expect to befully exposed to currency fluctuations relative to the U.S. dollar.

The values of non-U.S. currencies may fluctuate relative to theU.S. dollar in response to, among other factors, changes insupply and demand in the currency exchange markets, tradebalances, actual or perceived interest rate changes, long-termopportunities for investment and capital appreciation, intervention(or failure to intervene) by national governments, central banks,or supranational entities such as the International MonetaryFund, the imposition of currency controls, and other political orregulatory developments. For further information, please see“Market Disruption and Geopolitical Risk” below.

If a Fund trades in securities quoted or denominated in currenciesother than the U.S. dollar, or receives income in or takes a positionin a non-U.S. currency, and that currency becomes illiquid, theFund may not be able to convert that non-U.S. currency into U.S.dollars. As a result, the Manager may decide to purchase U.S.dollars in a parallel market in which the exchange rate ismaterially and adversely different. This will add to the cost oftrading. For further information, please see “Liquidity Risk” below.

Exchange rates for many currencies (e.g., some emergingcountry currencies) are particularly affected by exchange controlregulations.

Emerging Markets RiskInvestments in emerging markets are generally subject to agreater risk of loss than investments in developed markets.

Emerging market economies may experience greater volatility,lower trading volume and liquidity, greater risk of expropriation,nationalization, and social, political and economic instability thanmore established markets. Emerging markets economies mayalso have less developed accounting, legal and regulatorysystems, higher levels of inflation, deflation or currencydevaluation, greater risk of market shut down, and moresignificant governmental limitations on investment policy whencompared with typical developed markets. For example, thePublic Company Accounting Oversight Board, which regulatesauditors of U.S. public companies, is unable to inspect audit workpapers in certain foreign countries. Investors in foreign countriesoften have limited rights and few practical remedies to pursueshareholder claims, including class actions or fraud claims, andthe ability of the Securities and Exchange Commission(the “SEC”), the U.S. Department of Justice and other authoritiesto bring and enforce actions against foreign issuers or foreignpersons is limited.

Settlement and asset custody practices for transactions inemerging markets may differ from those in developed markets.Such differences may include delays in settlement and certainsettlement practices, such as delivery of securities prior to receiptof payment, which increase the likelihood of a “failed settlement.”

Failed settlements can result in losses. Similarly, the reliability oftrading and settlement systems in some emerging markets maynot be equal to that available in more developed markets, whichmay result in problems realizing investments. See “Non-U.S.Investment Risk” below.

In addition, issuers (including governments) in emerging marketcountries may have less financial stability than in other countries.There is also the potential for unfavorable action such asexpropriation, nationalization, embargo, and acts of war. As aresult, there will tend to be an increased risk of price volatility ininvestments in emerging market countries, which may bemagnified by currency fluctuations relative to the U.S. dollar.

The securities of emerging market companies may trade lessfrequently and in smaller volumes than more widely heldsecurities. They may also be reliant on a few industries,international trade or revenue from particular commodities. Theexistence of overburdened infrastructure and obsolete financialsystems also present risks in certain countries, as doenvironmental problems.

Market disruptions or substantial market corrections may limitvery significantly the liquidity of securities of certain companiesin a particular country or geographic region, or of all companiesin the country or region. A Fund may be unable to liquidate itspositions in such securities at any time, or at a favorable price, inorder to meet such Fund’s obligations. For example, restrictiveinvestment quotas, controls and other dealing limitationsmay apply.

For these and other reasons, investments in emerging marketsare often considered speculative. To the extent any Fund investsin emerging markets, it will be subject to all of the general risksdescribed in this Prospectus as well as special risks (some ofwhich are described in the SAI) that may affect the region wheresuch Fund invests. See also “Frontier Markets Risk” below.

Equity Securities RiskEquity securities represent an ownership interest, or the right toacquire an ownership interest, in an issuer. In addition tocommon stocks, equity securities include, without limitation,preferred stocks, convertible securities and warrants.Different types of equity securities provide different voting anddividend rights and priority in the event of a bankruptcy and/orinsolvency of the issuer. The Funds may invest in, and gainexposure to, common stocks and other equity securities throughpurchasing depositary receipts as described under “DepositaryReceipts” below.

Equity securities may experience significant price volatility, andthe market prices of equity securities can decline in a rapid orunpredictable manner.

The value of a company’s equity securities may fall as a result offactors directly relating to that company, such as decisions oractions taken by its management or employees, which couldinclude fraud or a criminal act, or lower demand for thecompany’s products or services. The value of an equity securitymay also fall because of factors affecting not just the company,but also companies in the same industry or in a number ofdifferent industries, such as increases in production costs.

The value of a company’s equity securities may also be affectedby changes in financial markets that are relatively unrelated tothe company or its industry, such as changes in interest rates orcurrency exchange rates or adverse circumstances involving thecredit markets. In addition, because a company’s equitysecurities rank junior in priority to the interests of bond holdersand other creditors, a company’s equity securities will usuallyreact more strongly than its bonds and other debt to actual orperceived changes in the company’s financial condition orprospects. The market prices of equity securities trading at highmultiples of current earnings often are more sensitive to changesin future earnings expectations than the market prices of equitysecurities trading at lower multiples.

The Funds may invest in the equity securities of issuers withsmaller to medium-sized market capitalizations. See “Small- andMedium-Capitalization Securities Risk” below.

Depositary ReceiptsThe Funds may invest in depositary receipts, including AmericanDepositary Receipts (“ADRs”), European Depositary Receipts(“EDRs”) and Global Depositary Receipts (“GDRs”). ADRs aredollar-denominated receipts issued generally by domesticbanks and representing the deposit with the bank of a security ofa non-U.S. issuer, and are publicly traded on exchanges or over-the-counter in the United States. EDRs are receipts similarto ADRs and are issued and traded in Europe. GDRs may beoffered privately in the United States and also traded in public orprivate markets in other countries. Investments in non-U.S.issuers through ADRs, GDRs, EDRs, and other types ofdepositary receipts generally involve risks applicable to othertypes of investments in non-U.S. issuers, including political,regulatory, and economic risks. Investments in depositaryreceipts may similarly be less liquid and more volatile than theunderlying securities in their primary trading market.

The values of depositary receipts may decline for a number ofreasons relating to the issuers or sponsors of the depositaryreceipts, including, but not limited to, insolvency of the issuer orsponsor. Investing in these instruments exposes a Fund to creditand counterparty risk with respect to the issuer of the ADR, EDRor GDR, in addition to the risks of the underlying investment.There may be less publicly available information regarding theissuer of the securities underlying a depositary receipt than ifthose securities were traded directly in U.S. securities markets.If a depositary receipt is denominated in a different currency thanits underlying securities, the Fund will be subject to the currencyrisk of both the investment in the depositary receipt and theunderlying security. Holders of depositary receipts may also havelimited or no rights to take action with respect to the underlyingsecurities or to compel the issuer of the receipts to take action.

Depositary receipts may be sponsored or unsponsored. Althoughthe two types of depositary receipt facilities are similar, there aredifferences regarding a holder’s rights and obligations and thepractices of market participants. With sponsored facilities, theunderlying issuer typically bears some of the costs of thedepositary receipts (such as dividend payment fees of thedepositary), although most sponsored depositary receipt holdersmay bear costs such as deposit and redemption fees.Depositaries of most sponsored depositary receipts agree todistribute notices of shareholder meetings, voting instructions,

and other shareholder communications and financial informationto the depositary receipt holders at the underlying issuer’srequest. Holders of unsponsored depositary receipts generallybear all the costs of the facility. The depositary usually chargesfees upon the deposit and redemption of the underlyingsecurities, the conversion of dividends into U.S. dollars or othercurrency, the disposition of non-cash distributions, and theperformance of other services. The depositary of anunsponsored facility frequently is under no obligation to distributeshareholder communications received from the underlying issueror to pass through voting rights with respect to the underlyingsecurities to depositary receipt holders.

Convertible SecuritiesConvertible securities are generally bonds, debentures, notes,preferred stocks, synthetic convertible securities and othersecurities or investments that may be converted or exchanged(by the holder or issuer) into equity securities of the issuer (orcash or securities of equivalent value). A convertible securitymay be called for redemption or conversion by the issuer after aparticular date and under certain circumstances (including aspecified price) established upon issue. If a convertible securityheld by a Fund is called for redemption or conversion, the Fundcould be required to tender it for redemption, convert it into theunderlying common stock or sell it to a third party. A convertiblesecurity will normally also provide income and is subject tointerest rate risk.

Convertible securities typically provide yields lower thancomparable non-convertible securities. Their values may be morevolatile than those of non-convertible securities, reflectingchanges in the values of the securities into which they areconvertible. Convertible securities may also be subordinate toother debt securities issued by the same issuer. Issuers ofconvertible securities are often not as strong financially asissuers with higher credit ratings.

Participatory NotesFrom time to time, a Fund may use participatory notes (“P-Notes”)to gain exposure to securities in certain foreign markets. P-Notesare a type of derivative that generally are traded over-the-counterand constitute general unsecured contractual obligations of thebanks or broker-dealers that issue them. Generally, banks andbroker-dealers associated with non-U.S. based brokerage firmsbuy securities listed on certain foreign exchanges and then issueP-Notes which are designed to replicate the performance of thesecurities and markets. The performance results of P-Notes willnot replicate exactly the performance of the securities or marketsthat the notes seek to replicate due to transaction costs and otherexpenses. The return on a P-Note that is linked to a particularunderlying security generally is increased to the extent of anydividends paid in connection with the underlying security.However, the holder of a P-Note typically does not receive votingor other rights as it would if it directly owned the underlyingsecurity, and P-Notes present similar risks to investing directly inthe underlying security. Additionally, P-Notes entail the risk thatthe counterparty or issuer of the P-Note may not be able to fulfillits obligations, that the holder and counterparty or issuer maydisagree as to the meaning or application of contractual terms, orthat the instrument may not perform as expected. Additionally,while P-Notes may be listed on an exchange, there is no

guarantee that a liquid market will exist or that the counterpartyor issuer of a P-Note will be willing to repurchase suchinstrument when a Fund wishes to sell it. For further informationabout some of the risks, please see “Emerging Markets Risk,”“Liquidity Risk,” “Market Disruption and Geopolitical Risk,” and“Non-U.S. Investment Risk” in this section.

Preferred SecuritiesPreferred stocks (or “preferred securities”) represent equityinterests in a company that generally entitles the holder toreceive, in preference for the holders of other stocks such ascommon stocks, dividends and a fixed share of the proceedsresulting from a liquidation of the company. Preferred securitiesmay pay fixed or adjustable rates of return and are subject toissuer-specific risks.

Dividends for preferred securities are typically paid afterpayments to debt and bond holders. Unlike debt securities,dividend payments on a preferred security typically must bedeclared by the issuer’s board of directors. An issuer’s board ofdirectors is generally under no obligation to pay dividends.A preferred security may therefore lose substantial value if theboard of directors of the issuer decides not to pay dividends.Further, because many preferred securities pay dividends at afixed rate, their market price can be sensitive to changes ininterest rates. If a Fund owns a preferred stock that is deferringits distribution, it may also be required to recognize income fortax purposes despite the fact that it is not receiving currentdistributions with respect to this position.

Preferred security holders commonly have no or limited votingrights with respect to the issuing company, which will limit theability of the Fund to influence the issuer.

Many preferred securities allow holders to convert the preferredsecurities into common stock of the issuer. Consequently, theirmarket price can be sensitive to changes in the value of theissuer’s common stock. Declining common stock values may alsocause the value of the Fund’s investments to decline.

Preferred securities often have call features which allow theissuer to redeem the security at its discretion. The redemption ofa preferred security having a higher than average yield maycause a decrease in the Fund’s yield.

Preferred stocks may trade less frequently and in a more limitedvolume and may be subject to more abrupt or erratic pricemovements than many other securities, such as common stocks,corporate debt securities, and U.S. government securities.

Focused Investment RiskFunds whose investments are focused in related, or a limitednumber of, countries, regions, sectors, companies or industries(e.g., different industries within broad sectors, such as technologyor financial services), or in securities from issuers with highpositive correlations to one another, are subject to greater overallrisk than funds whose investments are more diversified.

A Fund that invests in the securities of a limited number ofissuers is particularly exposed to adverse developments affectingthose issuers. In such cases, a decline in the market price of aparticular security held by the Fund is likely to affect the Fund’sperformance more than if the Fund invested in the securities of alarger number of issuers.

To the extent that a Fund focuses its investments in securitiesdenominated in a particular foreign currency or in investmentstied economically to (or related to) a narrowly defined geographicarea, it will be subject to increased risks, when compared withmore diversified funds. The political and economic prospects ofone country or group of countries within the same geographicregion may affect other countries in that region. Similarly, arecession, debt crisis or decline in currency valuation in onecountry can spread to other countries. Furthermore, companiesin a particular geographic region or country may be sensitive tothe same events, such as weather, natural disasters, publichealth crises, or events affecting other companies in that regionor country because of common characteristics, risk exposuresand regulatory burdens. Issuers in the same area may also reactsimilarly to specific economic, market, political or otherdevelopments. See also “Non-U.S. Investment Risk” below.

A Fund that focuses its investments in a certain type of issuer willbe particularly vulnerable to events affecting such type of issuer.Also, certain Funds may have greater risk to the extent theyinvest a substantial portion of their assets in a group of relatedindustries (or “sectors”). The industries comprising any particularsector and investments in a particular foreign currency or in anarrowly defined geographic area outside the United States mayshare common characteristics, are often subject to similarbusiness risks and regulatory burdens, and react similarly toeconomic, market, political or other developments.

Furthermore, certain issuers, industries and regions may beadversely affected by the impacts of climate change on thedemand for and the development of goods and services andrelated production costs, and the impacts of legislation,regulation and international accords related to climate change,as well as any indirect consequences of regulation or businesstrends driven by climate change.

Frontier Markets RiskFrontier markets are those emerging markets that are consideredto be among the smallest, least mature and least liquid and, as aresult, may be more volatile and less liquid than investments inmore developed markets or in other emerging market countries.Some of these markets may have unstable governments,economies based on only a few industries and securities marketsthat trade only a limited number of securities. Many frontiermarkets do not have well-developed regulatory systems anddisclosure standards may be less stringent than those of moredeveloped markets. The risks of expropriation, nationalization,and social, political, and economic instability are greater infrontier markets than in more developed markets. These risks,which are characteristic of many emerging markets generally,may be especially heightened in frontier markets, due to political,economic, financial, or other factors.

Geographic Focus RiskA Fund that focuses its investments in a limited number ofcountries or geographic regions will not offer the same level ofdiversification of risks as a more broadly global fund because itwill be exposed to a smaller geographic area. The performanceof a Fund that is less diversified across countries or geographicregions will be closely tied to market, currency, economic,political, environmental, or regulatory conditions anddevelopments in the countries or regions in which the Fund

invests, and may be more volatile than the performance of amore geographically-diversified portfolio.

Government and Regulatory RiskGovernmental and regulatory authorities in the United States andother countries, have taken, and may in the future take, actionsintervening in the markets in which a Fund invests and in theeconomy more generally. Governmental and regulatory authoritiesmay also act to increase the scope or burden of regulationsapplicable to a Fund or to the companies in which a Fund invests.The effects of these actions on the markets generally, and aFund’s investment program in particular, can be uncertain andcould restrict the ability of a Fund to fully implement its investmentstrategies, either generally, or with respect to certain securities,industries, or countries. For example, sanctions or otherinvestment restrictions imposed by governments could preclude aFund from investing in certain issuers or cause a Fund to sellinvestments at a disadvantageous time; new regulations on socialmedia companies or new anti-trust regulations could adverselyaffect the value of certain growth stocks held by a Fund; and newregulations promulgated by securities regulators could increasethe costs of investing in a Fund by increasing expenses borne bythe Fund in order to comply with such regulations.

By contrast, markets in some non-U.S. countries historically havebeen subject to little regulation or oversight by governmental orregulatory authorities, which could heighten the risk of loss dueto fraud or market failures in those countries. For example, aforeign government’s decision not to subject companies touniform accounting, auditing and financial reporting standards,practices, and requirements comparable to those applicable toU.S.-based companies could increase the risk that accountingfraud goes undetected. The lack of government-enforcedoversight may result in investors having limited rights and fewpractical remedies to pursue shareholder claims.

Furthermore, governments, agencies, or other regulatory bodiesmay adopt or change laws or regulations that could adverselyaffect a Fund or the market value of an instrument held by aFund. The Manager cannot predict the effects of any new laws orregulation that may be implemented, and there can be noassurance that any new laws or regulations will not adverselyaffect a Fund’s ability to achieve its investment objective. Forexample, financial entities, such as investment companies andinvestment advisers, are generally subject to extensivegovernment regulation which may change frequently and havesignificant adverse consequences on a Fund. Similarly,investments in certain industries, sectors, or countries may alsobe subject to extensive regulation. Economic downturns andpolitical changes can trigger economic, legal, budgetary, tax, andother regulatory changes. Regulatory changes may impact theway a Fund is regulated or the way a Fund’s investments areregulated, affect the expenses incurred directly by a Fund andthe value of its investments, and limit and/or preclude a Fund’sability to pursue its investment strategy or achieve its investmentobjective.

Growth Stock RiskThe prices of growth stocks may be based largely onexpectations of future earnings, and can decline rapidly andsignificantly in reaction to negative news about various factors,such as earnings, revenues, the economy, political developments,

or other news. Growth stocks may underperform stocks in otherbroad style categories (and the stock market as a whole) overany period of time. Growth stocks may shift in and out of favorwith investors generally, sometimes rapidly, depending onchanges in market, economic, and other factors. As a result, attimes when it holds investments in growth stocks, the Fund mayunderperform other investment funds that favor differentinvestment styles. Because growth companies typically reinvesttheir earnings, growth stocks typically do not pay dividends atlevels associated with other types of stocks, if at all.

Impact RiskA Fund may not be successful in assessing and identifyingcompanies that have or will have a positive impact or support agiven position. A Fund could invest in companies that ultimatelyhave a negative impact, or no impact, on addressing a globalchallenge, or on environmental, social and/or governance(“ESG”) matters. A company’s position or ability to have animpact (or the Manager’s assessment of a company’s position orpotential impact) may change over time, which could cause aFund to temporarily hold securities that are not consistent witha Fund’s investment principles. In evaluating a company, theManager is dependent upon information and data that may beincomplete, inaccurate or unavailable, which could cause theManager to incorrectly assess a company’s social orenvironmental performance or position. Successfulimplementation of a Fund’s investment strategy will depend onthe Manager’s skill in appropriately identifying and analyzingmaterial ESG factors, and these factors may be evaluateddifferently by different managers, and may mean differentthings to different people. See also “Socially ResponsibleInvesting Risk.”

Information Technology RiskThe Funds, their service providers, and other market participantsincreasingly depend on complex information technology andcommunications systems. These systems are subject to anumber of different threats or risks that could adversely affect theFunds and their shareholders, despite the efforts of the Fundsand their service providers to adopt technologies, processes, andpractices intended to mitigate these risks.

Unauthorized third parties may attempt to improperly access,modify, disrupt the operations of, or prevent access to thesesystems of the Funds, the Funds’ service providers,counterparties, or other market participants or data within thosesystems (each, a “cyber-attack”). Successful cyber-attacksagainst, or security breakdowns of, a Fund, the Manager, or acustodian, transfer agent, or other affiliated or third-party serviceprovider may adversely affect the Funds or their shareholders. Ingeneral, cyber-attacks are deliberate, but unintentional eventsmay have similar effects. Power or communications outages, actsof god, information technology equipment malfunctions,operational errors, and inaccuracies within software or dataprocessing systems may also disrupt business operations orimpact critical data.

Cyber-attacks, and other technical issues may interfere with theprocessing of shareholder or other transactions, affect a Fund’sability to calculate its net asset value, cause the release ofprivate shareholder information or confidential Fund information,impede trading, cause reputational damage, and subject a Fund

to regulatory fines, penalties or financial losses, reimbursementor other compensation costs, and additional compliance costs.They may render records of Fund assets and transactions,shareholder ownership of Fund shares, and other data integral tothe functioning of the Fund inaccessible or inaccurate orincomplete. There is also a risk that cyber-attacks may notbe detected.

Market events may also occur at a pace that overloads currentinformation technology and communication systems andprocesses of the Funds, the Funds’ service providers, or othermarket participants, affecting their ability to conduct the Funds’operations.

Similar types of information technology risks are present forissuers of securities or other instruments in which the Fundsinvest, which could result in material adverse consequences forsuch issuers, and may cause the Funds’ investments tolose value.

The Funds and their service providers have established businesscontinuity and other plans and processes to address thepossibility of cyber-attacks, disruptions, or failures. However,there are inherent limitations in such plans and processes,including that they do not apply to third parties, the possibility thatrisks may not have been identified or new risks may emerge inthe future. The Funds also cannot directly control any informationsecurity plans and systems put in place by their serviceproviders, counterparties, issuers in which the Funds invest, orsecurities markets and exchanges. In addition, such third-partiesmay have limited indemnification obligations to the Manager orthe Funds.

Investment Style RiskThe Manager actively makes investment decisions for the Fundsthrough bottom-up stock selection. Accordingly, each Fund willhave risk characteristics that differ from its benchmark index. TheManager’s judgments about the attractiveness, relative value, orpotential appreciation of a particular stock may prove to beincorrect and cause the Fund to lose money or underperformcompared to its benchmark index. There can be no assurancethat the Manager’s investment decisions will produce the desiredresults. There can also be no assurances that the Manager isable to identify a sufficient number of potential investments tomeet a Fund’s investment strategy. This risk is heightened forFunds with more focused investment strategies that rely onidentifying a small number of companies the Manager believespresent truly outstanding investment opportunities.

IPO RiskEach Fund may purchase securities in IPOs. These securities aresubject to many of the same risks of investing in companies withsmaller market capitalizations. Securities issued in IPOs have notrading history, and information about the companies may beavailable for very limited periods. In addition, the prices ofsecurities sold in IPOs may be highly volatile. At any particulartime or from time to time a Fund may not be able to invest insecurities issued in IPOs, or invest to the extent desired because,for example, only a small portion (if any) of the securities beingoffered in an IPO may be made available to such Fund. Inaddition, under certain market conditions a relatively smallnumber of companies may issue securities in IPOs. Similarly, as

the number of funds to which IPO securities are allocatedincreases, the number of securities issued to any one fund, ifany, may decrease. The investment performance of a Fundduring periods when it is unable to invest significantly or at all inIPOs may be lower than during periods when the Fund is able todo so. In addition, as a Fund increases in size, the impact ofIPOs on the Fund’s performance will generally decrease.

Japan RiskInvesting in Japan may involve greater geopolitical, economic,and environmental risk than investing in the United States orother developed economies. For example, despite Japan’s recenteconomic growth and emerging economic relationships withneighboring Southeast Asian countries, the growth of theJapanese economy has been behind that of other majordeveloped economies. Part of the reason for this is that Japan,like many Asian countries, is still heavily dependent uponinternational trade, such as oil imports, and thus susceptible tothe adverse effects of trade barriers, exchange controls, andother measures imposed or negotiated by the countries withwhich they trade. One trading partner in particular is China,whose political relationship with Japan has, at times, beenstressed. Such rising political tensions could adversely affect theJapanese economy and destabilize the region.

The value of Japan’s currency, the yen, has been susceptible tofluctuations. Increases in its value may cause a decline in exportsthat could weaken the Japanese economy. Japan has in the past,countered drastic shifts in its currency by intervening in thecurrency markets in an attempt to maintain or reduce the value ofthe yen. This intervention in the currency markets could causethe value of the yen to swing sharply and unpredictably andcould cause losses to investors.

Japan has an aging population and a significant populationdecline, which has resulted in a shrinking workforce. Its labormarket appears to be undergoing fundamental structuralchanges, as it has shifted from a labor market familiar withlifetime employment to a market adjusted to meet the need forincreased labor mobility. This change in the labor market mayadversely affect Japan’s economic competitiveness. Furthermore,natural disasters, such as earthquakes, volcanoes, typhoons, andtsunamis have and may continue to pose negative effects on theJapanese economy.

Investing in issuers located in Japan also exposes a Fund toadditional risks, as further described in this section under“Asia Risk”, “Non-U.S. Investment Risk”, and “Market Disruptionand Geopolitical Risk” and in the SAI under “Special Risks ofInvesting in Asian Securities.”

Large-Capitalization Securities RiskSecurities issued by large-capitalization companies may presentrisks not present in smaller companies. For example, largercompanies may be unable to respond as quickly as smaller andmid-sized companies to competitive challenges or to changes inbusiness, product, financial, or other market conditions. Largercompanies may not be able to maintain growth at the high ratesthat may be achieved by smaller companies, especially duringstrong economic periods. Returns on investments in securities oflarge companies could trail the returns on investments insecurities of smaller and mid-sized companies.

Liquidity RiskLiquidity risk is the risk that a Fund may not be able to dispose ofsecurities or close out derivatives transactions readily at afavorable time or prices (or at all) or at prices approximatingthose at which the Fund currently values them. For example,certain investments may be subject to restrictions on resale, maytrade in the over-the-counter market or in limited volume, or maynot have an active trading market. Such investments may also beparticularly susceptible to valuation risk. See “Valuation Risk”below.

Liquidity risk may be magnified during periods of changinginterest rates, significant shareholder redemptions, or marketturmoil.

The Funds are all subject to the risk that low trading volume, lackof a market maker, large positions in securities of particularissuers, or legal restrictions (including daily price fluctuation limitsor ‘circuit breakers’) could make any investment illiquid. Themarket for certain investments may also become illiquid underadverse market or economic conditions independent of anyspecific adverse changes in the conditions of a particular issuer.For example, securities issued by the U.S. Treasury haveexhibited periods of greatly reduced liquidity when disruptions infixed income markets have occurred, such as the eventssurrounding the bankruptcy of Lehman Brothers in 2008.

An inability to sell a portfolio position can adversely affect aFund’s value or prevent the Fund from being able to takeadvantage of other investment opportunities. In addition, it maybe difficult for a Fund to value illiquid securities accurately.Securities of issuers in emerging markets and frontier marketsmay be particularly susceptible to this risk. See “EmergingMarkets Risk” and “Frontier Markets Risk” above.

Illiquid securities may also trade at a discount from comparable,more liquid investments and may be subject to wide fluctuationsin market value. Illiquid securities are more susceptible than othersecurities to price declines when market prices decline generally.

Furthermore, disposal of illiquid securities may entail registrationexpenses and other transaction costs that are higher than thosefor liquid securities. For example, a Fund may hold restrictedsecurities and there can be no assurance that a trading marketwill exist at any time for any particular restricted security.Limitations on the resale of these securities may have anadverse effect on their marketability, and may prevent a Fundfrom disposing of them promptly at reasonable prices. A Fundmay have to bear the expense of registering the securitiesfor resale and the risk of substantial delays in effectingthe registration.

If a Fund holds illiquid securities it may be forced to sell othersecurities or instruments that are more liquid, but at anunfavorable price, time and conditions, in order to meetredemption requests. A Fund may seek to borrow money to meetits obligations (including among other things redemptionobligations) if it is unable to dispose of illiquid investments,resulting in borrowing expenses and possible leveraging of aFund. In some cases, due to unanticipated levels of illiquidity aFund may choose to meet its redemption obligations wholly or inpart by distributions of assets in-kind.

Mutual funds with principal investment strategies that involvesecurities of companies with smaller market capitalizations,non-U.S. securities, Rule 144A securities, derivatives orsecurities with substantial market or credit risk tend to have thegreatest exposure to liquidity risk.

Rule 22e-4 under the 1940 Act requires each Fund to adopt aliquidity risk management program to assess and manage itsliquidity risk. Under its program, a Fund is required to classify itsinvestments into specific liquidity categories and monitorcompliance with limits on investments in illiquid securities. Whilethe liquidity risk management program attempts to assess andmanage liquidity risk, there is no guarantee it will be effective inits operations and it may not reduce the liquidity risk inherent in aFund’s investments.

Long-Term Investment Strategy RiskThe Funds pursue a long-term investment approach, typicallyseeking returns over a period of several years, which cancomprise a full market cycle or more. This investment style maycause a Fund to lose money or underperform compared to itsbenchmark index or other mutual funds over extended periodsof time, and a Fund may not perform as expected in the longterm. The market price of the Funds’ investments mayfluctuate daily due to economic and other events that affectparticular companies and other issuers or the market as a whole.Short- and medium-term price fluctuations may be especiallypronounced in less developed markets or in companies withlower market capitalizations in which the Funds may invest.

Investments in certain industries or markets may be subject towider variations in performance as a result of special riskscommon to such markets or industries. For example, informationtechnology companies may have limited product lines, markets orfinancial resources and may be affected by worldwidetechnological developments and their products and services mayquickly become outdated. Similarly, emerging market economiesmay experience lower trading volume and liquidity, greater risk ofexpropriation, nationalization, and social, political and economicinstability than more developed markets, which may result ingreater volatility and significant short- or medium-term pricefluctuations.

An investment in the Funds may be more suitable for long-terminvestors who can bear the risk of short- or medium-termfluctuations in the value of a Fund’s portfolio, including short- ormedium-term losses.

Market Disruption and Geopolitical RiskGeopolitical, environmental and other events may disruptsecurities markets and adversely affect global economies andmarkets. These disruptions could prevent the Funds fromimplementing their investment strategies and achieving theirinvestment objectives, and increase the Funds’ exposure to theother risks detailed in this Prospectus. Given the increasinginterdependence among global economies and markets,conditions in one country, market, or region might adversely affectmarkets, issuers, and/or foreign exchange rates in othercountries, including the U.S.

War, terrorism, public health crises, and geopolitical events, suchas sanctions, tariffs, trade disputes, the imposition of exchange

controls or other cross-border trade barriers, have led, and in thefuture may lead, to increased short-term market volatility andmay have adverse long-term effects on U.S. and world economiesand markets generally. Terrorism in the U.S. and around theworld has had a similar global impact and has increasedgeopolitical risk.

Natural and environmental disasters, such as earthquakes andtsunamis, can be highly disruptive to economies and markets,adversely impacting individual companies and industries,securities markets, interest rates, credit ratings, inflation, investorsentiment, and other factors affecting the value of the Funds’investments. Similarly dramatic disruptions can be caused bycommunicable diseases, epidemics, pandemics, plagues andother public health crises.

Communicable diseases, including those that result in pandemicsor epidemics, may pose significant threats to human health, andsuch diseases, along with any efforts to contain their spread, maybe highly disruptive to both global and local economies andmarkets, with significant negative impact on individual issuers,sectors, industries, and asset classes. Significant public healthcrises, including those triggered by the transmission of acommunicable disease and efforts to contain it may result in,among other things, border closings and other significant travelrestrictions and disruptions, significant disruptions to businessoperations, supply chains and customer activity, lower consumerdemand for goods and services, event cancellations andrestrictions, service cancellations, reductions and other changes,significant challenges in healthcare service preparation anddelivery, and prolonged quarantines, as well as general concernand uncertainty. All of these disruptive effects were present, forexample, in the global pandemic linked to the outbreak ofrespiratory disease caused by a novel coronavirus designated asCOVID-19 that was first reported in China in December 2019.The effects of any disease outbreak may be greater in countrieswith less developed disease prevention and control programs andmay also exacerbate other pre-existing political, social,economic, market and financial risks. A pandemic and its effectsmay be short term or may last for an extended period of time,and in either case can result in significant market volatility,exchange trading suspensions and closures, declines in globalfinancial markets, higher default rates, and a substantialeconomic downturn or recession. The foregoing could impair aFund’s ability to maintain operational standards (such as withrespect to satisfying redemption requests), disrupt the operationsof a Fund’s service providers, adversely affect the value andliquidity of a Fund’s investments, and negatively impact a Fund’sperformance, and overall prevent a Fund from implementing itsinvestment strategies and achieving its investment objective.

Certain locations and industries may be particularly susceptibleto this risk, and other risks may be heightened by such events.See, for example, China Risk, Emerging Markets Risk, FrontierMarkets Risk, Information Technology Risk, Japan Risk, LiquidityRisk, Service Provider Risk, and Valuation Risk.

Securities and financial markets may be susceptible to marketmanipulation or other fraudulent trade practices, which coulddisrupt the orderly functioning of these markets or adverselyaffect the values of investments traded in these markets,including investments held by the Funds.

Market disruptions, including sudden government interventions(e.g., currency controls), can also prevent the Funds fromimplementing their investment strategies efficiently and achievingtheir investment objectives. For example, a market disruption mayadversely affect the orderly functioning of the securities marketsand may cause the Funds’ derivatives counterparties todiscontinue offering derivatives on some underlying securities,reference rates, or indices, or to offer them on a morelimited basis.

While the U.S. government has honored its credit obligationscontinuously for more than 200 years, it remains possible that theU.S. could default on its obligations. While it is impossible topredict the consequences of such an unprecedented event, it islikely that a default by the U.S. would be highly disruptive to theU.S. and global securities markets and could significantly impairthe value of the Funds’ investments. Similarly, political eventswithin the U.S. can result in the shutdown of governmentservices, which could negatively affect the U.S. economy,decrease the value of many Fund investments, and increaseuncertainty in or impair the operation of the U.S. or othersecurities markets.

Uncertainties regarding the viability of the European Union havedisrupted and may continue to disrupt markets in the U.S. andaround the world. If one or more countries leave the EuropeanUnion or the European Union dissolves, the world’s securitiesmarkets would likely be significantly disrupted and the Manager’sbusiness may be adversely affected. In June 2016, the UnitedKingdom held a referendum in which voters approved an exitfrom the European Union, commonly referred to as “Brexit.” TheUnited Kingdom formally left the European Union on January 31,2020. There is still a significant degree of uncertainty about thepotential consequences of Brexit. Brexit may cause increasedvolatility and have a significant adverse impact on world financialmarkets, other international trade agreements, and the UnitedKingdom and European Union economies, as well as the broaderglobal economy for some time. The consequences of the UnitedKingdom’s or another country’s exit from the European Unionand/or Eurozone also could threaten the stability of the euro forremaining countries and could negatively affect the financialmarkets of other countries in the European region and beyond.

Because of the fast-moving nature of current U.S.-China tradedisputes, there is a heightened risk that events occurring after theclose of Chinese markets may have a material impact on thevalue of Chinese securities held by a Fund. The likelihood ofsuch an occurrence and impact of such events may be difficult toassess before a Fund’s Pricing Point (as defined below) on thesame day, which may impact the accuracy of the NAV per sharecalculated by a Fund on a given day. The Funds maintain policiesand procedures intended to mitigate this risk.

Market RiskMarket risk is the risk of unfavorable market-induced changes inthe value of securities owned by a Fund.

Market prices of investments held by the Funds are volatile andwill go up or down, sometimes rapidly or unpredictably. Theprices of investments can change substantially due to variousfactors including, but not limited to, economic growth orrecession, changes in interest or currency rates, changes inactual or perceived creditworthiness of issuers, adverse investor

sentiment generally, market liquidity, real or perceived adversemarket conditions and the risks inherent in investment insecurities markets.

The total return of a Fund may consequently fluctuate within awide range, so you could lose money over short or even longperiods. Even if economic conditions do not change, the value ofan investment in a Fund could decline if the particular industries,sectors or companies in which a Fund invests do not perform wellor are adversely affected by events. Further, legal, political,regulatory and tax changes also may cause fluctuations inmarkets and securities prices.

New and Smaller-Sized Funds RiskNew funds and smaller-sized funds (including funds that arethinly capitalized or that have lost significant assets throughmarket declines or redemptions) will be subject to greater liquidityrisk due to their smaller asset bases. A large shareholderredemption from a small fund could require the fund to sellsecurities at disadvantageous times or prices or to delay paymentof redemption proceeds to a redeeming shareholder. In addition,in order to mitigate liquidity risk, new or smaller-sized funds maybe more likely to borrow under a credit facility (which wouldincrease fund expenses) or hold a proportionally higherpercentage of their assets in cash to meet shareholderredemptions (which could hamper performance).

A fund that has been recently formed will have limited or noperformance history for investors to evaluate. There can be noassurance that a new fund will reach or maintain a sufficientasset size to effectively implement its investment strategy. Inaddition, a fund’s gross expense ratio may fluctuate during itsinitial operating period because of the fund’s relatively smallerasset size and, until the fund achieves sufficient scale, a fundshareholder may experience proportionally higher fund expensesthan would be experienced by shareholders of a fund with alarger asset base.

Non-Diversification RiskCertain Funds are classified as a “non-diversified” fund. Anon-diversified fund may hold a smaller number of portfoliosecurities, with larger positions in each security it holds, thanmany other mutual funds. To the extent a Fund invests in arelatively small number of issuers, a decline in the market valueof a particular security held by the Fund may affect its valuemore than if it invested in a larger number of issuers. The valueof such Fund’s shares may be more volatile than the values ofshares of more diversified funds. See also “FocusedInvestment Risk.”

Non-U.S. Investment RiskInvesting in non-U.S. securities (i.e., those which are not primarilytraded on a United States securities exchange) involvesadditional and more varied risks than those typically resultingfrom investing in U.S. markets. Similar risks may apply tosecurities traded on a U.S. securities exchange that are issued bycompanies with significant exposure to non-U.S. countries.

The laws of some foreign countries may limit a Fund’s ability toinvest in securities of certain issuers located in those countries.

Baillie Gifford Funds – Prospectus

The securities of some foreign governments, companies, andsecurities markets are less liquid, and at times more volatile, thancomparable U.S. securities and securities markets. For example,the securities markets of many non-U.S. countries includesecurities of only a limited number of companies in a limitednumber of industries. As a result, the market prices of many ofthose securities fluctuate more than those of U.S. securities.

In addition, there may be a possibility of nationalization orexpropriation of assets, imposition of currency exchangecontrols, confiscatory taxation, and diplomatic developments thatcould adversely affect the values of the Fund’s investments incertain non-U.S. countries. There may be a greater risk ofeconomic turmoil as a result of political events (civil unrest,national elections, changes in political conditions and foreignrelations, imposition of exchange controls and repatriationrestrictions), social and economic events (labor strikes, risinginflation) and natural disasters, causing the Fund’s investments inthat country to experience gains or losses. The securities ofsome non-U.S. entities could also become subject to sanctions orembargoes that adversely affect the Fund’s investment.

Issuers of non-U.S. securities are subject to different, and oftenless comprehensive, accounting, reporting, custody, auditing anddisclosure requirements than domestic issuers. There may beless information publicly available about a non-U.S. entity thanabout a U.S. entity. Moreover, in certain non-U.S. countries, legalremedies available to investors may be more limited than thoseavailable with regard to U.S. investments. It may be difficult toobtain and enforce judgments against non-U.S. entities. Inaddition, some jurisdictions may limit a Fund’s ability to profitfrom short-term trading (as defined in the relevant jurisdiction).

Non-U.S. transaction costs, such as brokerage commissions andcustody costs may be higher than in the U.S. In some non-U.S.markets, custody arrangements for securities provide significantlyless protection than custody arrangements in U.S. markets.Prevailing custody and trade settlement practices (e.g., therequirement to pay for securities prior to receipt) could similarlyexpose a Fund to credit and other risks it does not have in theU.S. with respect to participating brokers, custodians, clearingbanks or other clearing agents, escrow agents, and issuers.

Non-U.S. securities are normally denominated and traded incurrencies other than the U.S. dollar. Consequently, the value ofthe Fund’s assets may be affected favorably or unfavorably bycurrency exchange rates, exchange control regulations, andrestrictions or prohibitions on the repatriation of non-U.S.currencies. See “Currency Risk” above.

Non-U.S. countries may also have additional requirementswith respect to the ownership of securities. For example, manynon-U.S. countries have additional reporting requirements thatmay be subject to interpretation or change without prior notice toinvestors. While the Funds make reasonable efforts to stayinformed of foreign reporting requirements relating to the Funds’foreign portfolio securities, no assurance can be given that theFunds will satisfy applicable foreign reporting requirements at alltimes. There are also special tax considerations which apply tosecurities of non-U.S. issuers and securities principally tradedoverseas. Income and gains with respect to investments incertain countries may be subject to withholding and other taxes.See “Tax” below and the SAI for further details.

Additionally, U.S. investors are required to maintain a license toinvest directly in many non-U.S. markets. These licenses areoften subject to limitations, including maximum investmentamounts. Once a license is obtained, a Fund’s ability to continueto invest directly is subject to the risk that the license will beterminated or suspended. If a license is terminated orsuspended, to obtain exposure to the market, the Fund may berequired to purchase ADRs, GDRs, shares of other funds thatare licensed to invest directly, or derivative instruments. Thereceipt of a foreign license by one of the Manager’s clients maypreclude other clients, including a Fund, from obtaining a similarlicense, and this could limit the Fund’s investment opportunities.In addition, the activities of another of the Manager’s clientscould cause the suspension or revocation of a license andthereby limit the Funds’ investment opportunities.

Service Provider RiskEach Fund is subject to the risk that the Manager will applytechniques and analyses to the Funds’ investment practices thatare not as successful as the techniques and analyses used byother investment advisers. There is no guarantee that theManager will be able to enhance the returns of the Funds orpreserve the Funds’ assets. The Manager also may fail to usederivatives effectively, including by choosing to hedge or not tohedge positions at disadvantageous times. The Manager’sjudgments about the attractiveness, relative value, or potentialappreciation of a particular sector, security, commodity orinvestment strategy or as to a hedging or allocation strategy mayprove to be incorrect, and may cause the Funds to incur losses.

There can be no assurance that key personnel of the Managerwill continue to be employed by the Manager. The loss of theirservices could have an adverse impact on the Manager’s abilityto achieve the Funds’ investment objectives. A change in laws orregulations due to political or economic events, such as Brexit,may impact the Manager’s ability to retain its portfolio managersand other key personnel. For additional information on Brexit see“Market Disruption and Geopolitical Risk” above.

The Funds are also subject to the risk of loss as a result of otherservices provided by the Manager and other service providers,including pricing, administrative, accounting, tax, legal, custody,transfer agency, and other services. The Funds currently utilizeentities affiliated with the Bank of New York Mellon to serve astransfer agent, administrator, custodian and fund accountingagent to the Funds. This arrangement could magnify lossesresulting from a systems failure affecting the Bank of New YorkMellon. Loss may be caused by inadequate procedures andcontrols, human error, system failures, negligence, misfeasanceor fraud by a service provider or insolvency of a service provider.For example, trading delays or errors (both human andsystematic) could prevent a Fund from benefiting from potentialinvestment gains or avoiding losses on the security.

Settlement RiskMarkets in different countries have different clearance andsettlement procedures. Certain markets may from time to time beunable to keep pace with the volume of transactions.

Delays in settlement may increase credit risk to the Funds or limitthe ability of the Funds to reinvest the proceeds of a sale ofsecurities. Delays in settlement may also subject the Funds to

penalties for their failure to deliver to on-purchasers of securitieswhose delivery to the Fund was delayed.

Delays in the settlement of securities purchased by a Fund mayalso limit the ability of such Fund to sell those securities at timesand prices it considers desirable, and may subject such Fund tolosses and costs due to its own inability to settle with subsequentpurchasers of the securities from it. A Fund may be required toborrow monies it had otherwise expected to receive in connectionwith the settlement of securities it has sold, in order to meet itsobligations to others.

Limits on the ability of the Funds to purchase or sell securitiesdue to settlement delays could increase any variance betweenthe Funds’ performance and that of their benchmark indices.

Small- and Medium-Capitalization Securities RiskThe securities of small- and medium-capitalization companiesmay be more volatile and may involve more risk than thesecurities of larger companies. These companies may havelimited product lines, markets or financial resources, may lack thecompetitive strength of larger companies, and may depend on afew key employees. In addition, these companies may have beenrecently organized and may have little or no track record ofsuccess. Similarly, the securities of small- and medium-sizedcompanies may trade less frequently and in smaller volumes thansecurities of larger companies. The prices of these securitiesmay consequently fluctuate more sharply than those of othersecurities, and the Funds may experience difficulty in establishingor closing out positions in these securities at prevailing marketprices. Moreover, there may be less publicly available informationabout the issuers of these securities or less market interest inthese securities than in the case of larger companies, both ofwhich can cause significant price volatility.

Some securities of small- and medium-sized issuers may also beilliquid or may be restricted as to resale. A Fund may therefore beunable to liquidate its positions in such securities at any time, orat a favorable price, in order to meet the Fund’s obligations.

Socially Responsible Investing RiskA Fund’s approach to socially responsible investing, including itsincorporation of ESG considerations in its investment process,may cause it to make different investments than funds that have asimilar investment universe and/or investment style but that donot incorporate such considerations in their investment strategyor processes. As a result, such Fund may forego opportunities tobuy certain securities when it might otherwise be advantageousto do so or sell securities when it might be otherwisedisadvantageous for it to do so. For instance, a Fund’s exclusionof investments in companies with significant fossil fuel exposuremay adversely affect the Fund’s relative performance at timeswhen such investments are performing well.

A Fund’s socially responsible investment process may also affectthe Fund’s exposure to certain sectors or types of investments,which may impact the Fund’s relative investment performancedepending on whether such sectors or investments are in or outof favor with the market. In addition, a Fund’s investments incertain companies may be susceptible to various factors thatmay impact their businesses or operations, including costsassociated with government budgetary constraints that impactpublicly funded projects and clean energy initiatives, the effects

of general economic conditions throughout the world, increasedcompetition from other providers of services, unfavorable taxlaws or accounting policies and high leverage.

A Fund’s portfolio managers are dependent on availableinformation to assist in the social evaluation process, and,because there are few generally accepted standards to use inevaluation, the process employed for a Fund may differ fromprocesses employed for other funds. Additionally, as a result ofthe Manager’s stewardship activities, a Fund may purchasesecurities with the intention of seeking to improve an issuer’sESG practices. Successful application of a Fund’s ESG investingstrategy and engagement efforts will depend on its portfoliomanagers’ ability to identify and analyze material ESG issues,and there can be no assurance that the strategy or techniquesemployed will be successful.

The Manager may seek to identify companies that it believes mayhave a positive societal impact, but investors may differ in theirviews of what constitutes positive or negative societal impactoutcomes. As a result, a Fund may invest in companies that donot reflect the beliefs and values of any particular investor.

See also “Impact Risk.”

Underlying Funds RiskA Fund that invests in U.S. or non-U.S. pooled investmentvehicles, such as ETFs, mutual funds, and private funds,(“Underlying Funds”) will be exposed to the risk that theUnderlying Fund does not perform as expected and indirectly toall of the risks applicable to an investment in such UnderlyingFunds. In addition, lack of liquidity in the Underlying Fund couldresult in its value being more volatile than the underlying portfolioof securities, and may limit the ability of a Fund to sell or redeemits interest in the underlying fund at a time or at a price it mightconsider desirable. The investment policies and limitations of theUnderlying Funds may not be the same as those of a Fund; as aresult, a Fund may be subject to additional or different risks, ormay achieve a reduced investment return, as a result of itsinvestment in Underlying Funds. If an Underlying Fund is anexchange-traded fund or other product traded on a securitiesexchange or otherwise actively traded, its shares may trade at apremium or discount to their net asset value, an effect that mightbe more pronounced in less liquid markets. A Fund bears itsproportionate share of the fees and expenses of any UnderlyingFund in which it invests.

The Manager or an affiliate may serve as investment adviser tosome Underlying Funds, leading to potential conflicts of interestand other risks. For example, the Manager would have anincentive to invest in Underlying Funds in need of seed capital,even if the expenses of such Underlying Funds are higher thanalternative investments or alternative investments would be moreappropriate for a Fund in light of its investment strategy.Investment by a Fund in an Underlying Fund may be beneficial tothe Manager or an affiliate in the management of the UnderlyingFund, by helping to achieve economies of scale or enhancingcash flows. Due to this and other factors, the Manager will, insome circumstances, have an incentive to invest a Fund’s assetsin an Underlying Fund sponsored or managed by the Manager orits affiliates in lieu of investments by a Fund directly in portfoliosecurities, or may have an incentive to invest in the affiliatedUnderlying Fund over a pool sponsored or managed by others.

Similarly, the Manager may have an incentive to delay or decideagainst the sale of interests held by a Fund in an UnderlyingFunds sponsored or managed by the Manager or its affiliates. It ispossible that other clients of the Manager or its affiliates willpurchase or sell interests in an Underlying Fund sponsored ormanaged by the Manager or its affiliates at prices and at timesmore favorable than those at which a Fund does so. In addition,the Manager’s fiduciary duty to an affiliated Underlying Fund maysubject a Fund to restrictions on redemptions in certaincircumstances, which may make a Fund’s investments inaffiliated Underlying Funds less liquid than investments in otherUnderlying Funds.

Valuation RiskIn certain circumstances, some of a Fund’s portfolio holdingsmay be valued on the basis of factors other than marketquotations by employing the fair value procedures adopted by theBoard. This may occur more often in times of market turmoil orreduced liquidity. There are multiple methods that can be used tovalue a portfolio holding when market quotations are not readilyavailable. The value established for any portfolio holding at apoint in time might differ from what would be produced using adifferent methodology or if it had been priced using marketquotations. Portfolio holdings that are valued using techniquesother than market quotations, including “fair valued” securities,may be subject to greater fluctuation in their valuations from oneday to the next than if market quotations were used.Technological issues or other service disruption issues involvingthird-party service providers may cause a Fund to value itsinvestments incorrectly. In addition, there is no assurance that aFund could sell or close out a portfolio position for the valueestablished for it at any time, and it is possible that a Fund wouldincur a loss because a portfolio position is sold or closed out at adiscount to the valuation established by a Fund at that time.Investors who purchase or redeem shares on days when a Fundis holding fair-valued investments may receive fewer or moreshares or lower or higher redemption proceeds than they wouldhave received if the Fund had not fair-valued the holding(s) orhad used a different valuation methodology.

Fund Fund (billions) daily net assets)

Upon termination of the Advisory Agreement at other thanquarter end, the Advisory Fee for the partial quarter shall bedetermined by reference to the termination date and shall beprorated accordingly.

Administration and Supervisory ServicesThe Manager is responsible for providing certain administrativeservices to Fund shareholders as well as coordinating,overseeing and supporting services provided to Fundshareholders by third parties, including financial intermediariesthat hold accounts with the Funds, pursuant to an Administrationand Supervisory Agreement between the Manager and the Truston behalf of each Fund (the “Administration and SupervisoryAgreement”). The Administration and Supervisory Agreementalso relates to the Class K and Institutional Class shares of otherseries of the Trust.

Under the Administration and Supervisory Agreement, eachFund pays to the Manager an Administration and SupervisoryFee quarterly, in arrears, with respect to Class K and InstitutionalClass shares at an annual rate of 0.17% of such Fund’s averagenet assets. For the fiscal year ended December 31, 2020, eachoperational Fund paid Administration and Supervisory Feesequal to 0.17% of such Fund’s average daily net assets. TheAdministration and Supervisory Fee and the Advisory Fee aretogether referred to as the “Management Fee.”

The Trust has adopted an Administration, Supervisory and Sub-Accounting Services Plan pursuant to Rule 12b-1 under the1940 Act with respect to Class K and Institutional Class shares ofeach Fund (the “Plan”). However, no distribution payments underRule 12b-1 have been authorized by the Board as of the date ofthis Prospectus, and no distribution fees under Rule 12b-1 arecurrently payable under the Plan. If the Board authorizesdistribution payments pursuant to Rule 12b-1 in the future for anyclass of shares, the Manager or another service provider mightcollect distribution fees under Rule 12b-1, but only afterappropriate authorization by the Board and after this Prospectus

has been updated to reflect such additional fees. Shoulddistribution payments under Rule 12b-1 be collected, these feeswould be paid out of the applicable Fund’s assets on an ongoingbasis, and over time these fees could increase the cost of yourinvestment and may cost you more than paying other types ofsales charges.

Participating Affiliate ArrangementsThe Manager has entered into a personnel-sharing arrangementwith its Hong Kong-based affiliate, Baillie Gifford Asia (HongKong) Limited (“Baillie Gifford Asia”).Pursuant to this arrangement, Baillie Gifford Asia acts as a“participating affiliate” of the Manager and certain employees ofBaillie Gifford Asia are treated as “associated persons” of theManager. In this capacity, these individuals are subject to theoversight of the Manager and its Chief Compliance Officer.These associated persons, on behalf of the Manager, providetrade execution and related services to the Funds. Thepersonnel-sharing arrangement is based on no-action letters ofthe staff of the SEC that permit SEC-registered investmentadvisers to rely on and use the resources of advisory affiliates,subject to certain conditions.

Baillie Gifford Asia is not registered as an investment adviser withthe SEC. The Manager may in the future enter into additionalpersonnel-sharing arrangements, including with its non-U.S.unregistered investment advisory affiliates, for a variety ofinvestment advisory services, including investment research andportfolio management.

ExpensesThe organizational and operational expenses of the Funds areborne by the relevant Fund, including but not limited to brokeragecommissions, transfer taxes and extraordinary expenses inconnection with its portfolio transactions, all applicable taxes,independent trustee compensation, interest charges, charges ofcustodians, auditing and legal expenses.

Certain expenses, not including advisory and custodial fees orother expenses related to the management of a Fund’s assets,may be allocated to a specific class of shares if those expensesare actually incurred in a different amount with respect to a class,or if services are provided with respect to a class that are of adifferent kind or to a different degree than with respect to theother class.

Baillie Gifford Funds – Prospectus

SHARES

Share ClassesThe Trust is authorized to issue Class K and InstitutionalClass shares of each Fund covered by this Prospectus.

How Shares are PricedEach share class has its own share price. The purchase price ofeach share class of a Fund’s shares is based on that class’s netasset value. The share price is computed for each share class asfollows:

— the total market value of all assets and fund-level liabilitiesof each Fund is calculated, then divided by the total amountof shares held in that Fund (the “Fund Asset Value”); then

— the market value of the assets for each class is calculatedon a pro-rata basis, based on the Fund Asset Value (the“Class Asset Value”); then

— the market value of the class-specific liabilities attributable toeach share class is calculated (the “Class Liabilities”); then

— the share price for each class is calculated by deducting theClass Liabilities from the Class Asset Value.

When shares are pricedThe net asset value for each share class will be determined as ofa particular time of day (the “Pricing Point”) on any day onwhich the NYSE is open for unrestricted trading. The PricingPoint is normally at the scheduled close of unrestricted tradingon the NYSE (generally 4:00 p.m. Eastern Time). In unusualcircumstances, the Funds may determine that the Pricing Pointshall be at an earlier, unscheduled close or halt of trading on theNYSE. The price at which purchase and redemption orders areeffected is based on the next calculation of the net asset valueafter the order is received in good order. “Good order” means,among other things, that your request includes completeinformation. In general, an order is in “good order” if it includes:(i) the trade date of the purchase or redemption; (ii) the name ofthe Fund and share class; (iii) the U.S. dollar amount of theshares, in the case of a redemption you may also providenumber of shares; (iv) the name and the account number setforth with sufficient clarity to avoid ambiguity; and (v) the relevantauthorized signatories. In the case of a purchase, immediatelyavailable funds must also be received prior to the Pricing Point.

The net asset value for each class may be affected by changes inthe value of currencies in relation to the U.S. dollar. This isbecause investments initially valued in currencies other than theU.S. dollar are converted to U.S. dollars using currency exchangerates obtained from pricing services at the Pricing Point on eachday that the NYSE is open for unrestricted trading. If you arebuying or selling shares, the share price you receive will be theshare price determined after the purchase or redemption requestis received by the applicable Fund (or your financial intermediary)in good order.

The net asset value of the Fund’s shares may change on dayswhen shareholders will not be able to purchase or redeem sharesof the Fund. This is because the Fund may invest in securitiesthat are primarily traded on foreign exchanges which may tradeat times or on days when the Fund does not price its shares.

Current net asset values per share for each Fund that hascommenced operation are available on the Funds’ website athttp://USmutualfund.bailliegifford.com.

How assets are valuedIn accordance with the Trust’s Pricing and Valuation Procedures,each Fund’s investments are valued at their fair market value asfollows:

1. If reliable market quotations are readily available, theinvestments will generally be valued at the last quoted saleprice on each business day or, if not traded on that businessday, at the most recent quoted bid price.

2. If reliable current market quotations are not readily availableor quotations are not believed to be reliable due to marketchanges that occur after the most recent availablequotations are obtained or for any other reason, the fairvalue of the investments will be assessed in accordance withthe pricing and valuation procedures of the Trust, as morefully described in the SAI. Such market changes may:

º relate to a single issuer or events relating to multipleissuers;

º be considered to include changes in the value of U.S.securities or securities indices; or

º occur after the close of the relevant market and beforethe time at which the applicable net asset value isdetermined.

Please see the section entitled “Purchase, Redemption, andPricing of Shares—Determination of Net Asset Value” in the SAIfor further information.

How to Buy or Exchange Shares

Purchase ProcessYou may purchase Institutional Class or Class K shares of anyFund by taking the following two steps:

1. Request a Purchase.If you purchase shares through a financial intermediary, youmay make a purchase for shares by making a request toyour intermediary. Your intermediary may charge you atransaction fee or other fee in return for its services.

For Class K, you may also email a purchase request to theBank of New York Mellon (the “Transfer Agent”) in a formatprescribed by the Manager, which includes:

º the name and class of the Fund;

º the exact name in which shares are to be registered;

º the shareholder account number;

º the dollar amount of shares to be purchased;

Restrictions on Buying or Exchanging Shares

Minimum InvestmentThe minimum initial investment for Class K is $10 million. Thereis no minimum investment amount for Institutional Class shares.The Fund may, at its discretion, permit a smaller minimum totalinvestment balance for Class K shares under certaincircumstances.

If you purchase or exchange shares through a financialintermediary, the intermediary may impose different investmentminimums.

Share Class EligibilityYou must be eligible for the share class you are applying for. TheFunds offer two classes of shares through this Prospectus:Class K and Institutional Class. Class K and InstitutionalClass shares of each Fund have the same investment objectivesand investments, but the different share classes have differentexpense structures and eligibility requirements. You shouldchoose a share class for which you are eligible, with the expensestructure that best meets your needs.

The principal differences between the share classes are asfollows:

Class K Institutional Class

(1) Except where otherwise noted in the relevant Fund Summary, the“Other Expenses” shown for Institutional Class shares in the FundSummaries under the heading “Annual Fund Operating Expenses”are based on historical expenses borne by InstitutionalClass shares during the last fiscal year. The impact on OtherExpenses of sub-accounting payments (if any) that are made byInstitutional Class shares is determined by rates charged byindividual financial intermediaries through which investors in thisClass typically hold their shares. As the composition of theseintermediaries change, the impact of sub-accounting payments onthe Other Expenses of Institutional Class will change. For Fundswhere Institutional Class shares were, during the Fund’s last fiscalyear, funded primarily by proprietary seed capital, the OtherExpenses for Institutional Class shares may reflect little or noimpact from sub-accounting payments, although this is expected tochange in the future as the share class grows. Where “OtherExpenses” have been estimated, this estimate includes sub-accounting expenses of 0.15% for Institutional Class.

Class K SharesThe following categories of investors and accounts may buy orexchange into Class K shares of a Fund, provided that they do

Buying, Selling, and Exchanging Shares throughFinancial Intermediaries

What is a financial intermediary?Financial intermediaries are firms that provide certainadministrative and account maintenance services to mutual fundinvestors. Financial intermediaries may include, among others,brokers, financial planners or advisers, banks, and insurancecompanies.

How do I access a Fund through a financial intermediary?Any financial intermediary which is properly authorized by theFunds can accept purchase, redemption and exchange orders ontheir behalf. The financial intermediary is responsible fortransmitting your transaction request and funds in good form andin a timely manner to the applicable Fund.

Orders received for a Fund by an authorized financialintermediary (or other financial intermediaries designated by thefinancial intermediary) prior to the Pricing Point will be deemed tohave been accepted by the Fund at that time and will beexecuted at that day’s closing share price.

The Funds will not be responsible for delays by the financialintermediary in transmitting your transaction request, includingtimely transfer of payment, to a Fund.

If you are purchasing, selling, exchanging or holding Fund sharesthrough a program of services offered by a financial intermediary,you may be required by the financial intermediary to payadditional fees. You should contact the financial intermediary forinformation concerning what additional fees, if any, may becharged.

What services are provided by financial intermediaries?The actual services provided, and the payments made for suchservices, will vary from intermediary to intermediary.

Examples of intermediary services include:

— establishing and maintaining one or more omnibus accountswith the Transfer Agent;

— establishing and maintaining sub-accounts and sub-accountbalances for each plan participant that may be a holder ofFund shares;

— processing orders by shareholders to purchase, redeem andexchange shares;

— transmitting to the Transfer Agent net purchase or netredemption orders reflecting purchase, redemption andexchange orders received by it with respect to Fundshareholders;

— receiving and transmitting the purchase price or redemptionproceeds relating to orders;

— mailing periodic reports, transaction confirmations and sub-account information to beneficial owners and planparticipants;

— answering inquiries about the Funds or a plan participant’ssub-account balances or distribution options;

— providing assistance to shareholders effecting changes totheir dividend options, account designations or addresses;

— disbursing income dividends and capital gains distributions;

— preparing and delivering to shareholders, and state andfederal authorities including the United States InternalRevenue Service (“IRS”), such information respectingdividends and distributions paid by the Funds as may berequired by law, rule or regulation; and

— withholding on dividends and distributions as may berequired by state or federal authorities from time to time.

How are financial intermediaries compensated?It is expected that Institutional Class shares of the Funds willmake payments, or reimburse the Manager or its affiliates forpayments they make, to financial intermediaries that providecertain administrative, recordkeeping, and account maintenanceservices.

The amount of such payments and/or reimbursement is subjectto the caps established by the Board and is reviewed by theTrustees periodically.

The nature and extent of sub-accounting services provided toInstitutional Class shareholders and the amount of sub-accounting fees charged to the Funds will vary among financialintermediaries. Financial intermediaries may choose to holdInstitutional Class shares and opt not to charge any sub-accounting fees with respect to a portion of, or even all of, theshares so held. Institutional Class shares bear sub-accountingexpenses on a class-wide basis. As such, the rate at which theseexpenses are incurred, as a percentage of Institutional Class netassets, will be a blended rate of the rates charged by variousfinancial intermediaries holding shares in the Funds. In instanceswhere this blended rate is higher than the rate charged to a Fundby your financial intermediary, you will bear the higher blendedrate instead of the lower rate charged to the Fund by yourfinancial intermediary. In instances where this blended rate islower than the rate charged to a Fund by your financialintermediary, you will bear the lower blended rate instead of thehigher rate charged to the Fund by your financial intermediary. Allpayments made by the Funds to financial intermediaries are forbona fide shareholder services and are not primarily intended toresult in the sale of Fund shares.

Additional information concerning payments the Fund, theManager or their affiliates may make to financial intermediaries,and the services provided by financial intermediaries, can befound in the SAI under “Manager—Payments to FinancialIntermediaries.”

How to Sell Shares

ProcessRedemption Request – You can redeem your shares by takingeither of the following steps:

1. Through your broker or financial intermediary. If you holdshares through a financial intermediary, you may redeemshares by making a request to your intermediary. Yourintermediary may charge you a transaction fee or other feein return for its services.

2. Email a redemption request to the Transfer Agent, in theManager’s prescribed form, which includes:

º the name and class of the Fund;

º the exact name in which shares are registered;

º the shareholder account number;

º the number of shares or the dollar amount of shares tobe redeemed;

º a signature by all owners of the shares, in accordancewith the form of registration;

º the capacity of the signatory, if the signatory is acting ina fiduciary capacity, or as an agent on behalf of acorporation, partnership or trust; and

º the trade date.

All emails containing a purchase request must be unencrypted.The email address for redemption requests sent to the TransferAgent is: [email protected].

Redemption orders cannot be cancelled after the Trust hasreceived a redemption request. This is the case even if therequest is received prior to the Pricing Point.

Redemption Payment – Cash payments will be transferred forpayment into your account after a request for redemption isreceived by the Trust in good order. The Funds generally expectto pay out redemption proceeds to redeeming shareholderswithin 1 business day following the trade date indicated in theredemption request, but have in the past, and may in the future,delay settlement of redemptions to the third business dayfollowing the trade date in response to unusually largeredemption requests, and each Fund reserves the right to satisfyredemption requests up to seven days following the trade dateindicated in the redemption request. The possibility of delayedsettlement is greater for smaller Funds or for Funds withparticularly concentrated investor bases. The Funds typicallymeet redemption requests by using holdings of cash and cashequivalents or by selling portfolio assets. The Funds may also,under normal or stressed market conditions, use a credit facilityor, if a Fund has received advanced notice of a shareholder’sintent to redeem, trade portfolio holdings ahead of the trade dateto meet significant requests for redemption.

If you request a whole or part in-kind distribution of securitiesheld by the Fund in lieu of cash, the Manager will grant this if itdetermines, in the Manager’s sole discretion, that to do so islawful and will not be detrimental to the best interests of theremaining shareholders of the Fund. This is subject to eachFund’s election under Rule 18f-1 described below under “Election

under Rule 18f-1.” If you intend to request a distribution in kind,please note:

— Securities distributed in connection with the request will bevalued in accordance with the Fund’s procedures forvaluation described under “How Shares are Priced.”

— Securities and assets distributed will be selected by theManager in accordance with procedures approved by theBoard and generally will represent a pro-rata distribution ofeach holding in the Fund’s portfolio, subject to certainexceptions under relevant procedures.

— You may incur market-imposed taxes or charges inconnection with assuming title to such securities from theFunds, and may incur brokerage charges on the sale of anysuch securities so received in payment of redemptions.

Change of Information – If you need to change or update youraccount information, you may do so through your financialintermediary, or by mailing or emailing the Transfer Agent adesignation of the new accounts and any change in the accountsoriginally designated for the depositing of funds. This must besigned by the relevant authorized signatories of the subscriber. AFund or its agent may take additional steps to verify changes toaccount information, especially bank account details, beforetransferring redemption amounts. If you hold an account directlywith the Transfer Agent, all redemptions and dividenddisbursements will be processed according to the bank accountdetails you provided upon your initial account set-up, unless youhave contacted the Transfer Agent to change those details.Please see the back cover of this Prospectus for information onhow to contact the Transfer Agent.

When you can redeem sharesShares may be redeemed on any day on which the NYSE is openfor trading.

Please note that the Trust may suspend the right of redemptionand may postpone payment for any Fund for more than sevendays during an emergency which makes it impracticable for aFund to dispose of its securities or to fairly determine the valueof the net assets of the Fund, or during any other periodpermitted by the SEC for the protection of investors.

Automatic RedemptionsEach Fund reserves the right to redeem or require the transfer ofany individual’s shares if:

— The holding of the shares by such person is unlawful;

— In the opinion of the Board or the Fund’s service providers,the holding might result in the Fund or the shareholders as awhole incurring any liability to taxation or suffering pecuniaryor material administrative disadvantage which the Fund orthe shareholders as a whole might not otherwise suffer orincur; or

— The Fund cannot verify your identity.

sometimes referred to as “market timing.” These practices maypresent risks to the Funds, including increased transaction costs,interference with the efficient management of the Funds, anddilution of investment returns.

Frequent, short-term trading, abusive trading practices andmarket timing (together, “Frequent Trading”), often in responseto short-term fluctuations in the market, are not knowinglypermitted by the Funds. The Funds do not accommodatefrequent purchases and redemptions of Fund Shares by Fundshareholders. Frequent Trading into and out of a Fund may harmthe Fund’s performance by disrupting portfolio managementstrategies and by increasing expenses. These expenses areborne by all Fund shareholders, including long-term investorswho do not generate such costs.

The Board has adopted a “Frequent Trading Policy” (the “Policy”)to discourage Frequent Trading. Under the Policy, the Fundsreserve the right to reject any exchanges or purchase orders or tosuspend redemptions by any shareholder engaging in FrequentTrading activities.

As a means to protect each Fund and its shareholders fromFrequent Trading in Class K and Institutional Class shares:

— The Transfer Agent arranges for the compilation, monitoringand reporting of account-level information on underlyingshareholder activity on a risk-based approach designed toidentify trading that could adversely impact the Funds;

— The Funds have obtained information from each FinancialIntermediary holding shares in an omnibus account with theFunds regarding whether the Financial Intermediary hasadopted and maintains procedures that are reasonablydesigned to protect the Funds against harmful short-termtrading;

— With respect to Funds that invest in securities that trade onforeign markets, pursuant to the Funds’ fair valuationprocedures, pricing adjustments may be made based oninformation received from a third-party, multi-factor fairvaluation pricing service; and

— The Board may from time to time consider whether it isnecessary or appropriate for a Fund to impose a redemptionfee not exceeding 2% that, in the Board’s judgment, isnecessary or appropriate to recoup the costs and limit anydilution resulting from frequent redemptions. Any suchredemption fee would be imposed only to manage the impactof ongoing frequent trading or other abusive tradingpractices and would not be imposed retrospectively onhistoric trades.

Under the Policy, Frequent Trading includes certain material“Round Trip” transactions (meaning a series of transactionswithin the same Fund and within a defined time period, consistingof either (a) a purchase or exchange, followed by a redemption orexchange, followed by a purchase or exchange; or (b) aredemption or exchange, followed by a purchase or exchange,followed by a redemption or exchange). If a shareholder engagesin Frequent Trading, the Funds may take certain remedial orpreventive measures, including rejecting any purchase, in wholeor in part. The Funds reserve the right to reject purchase orders

by any person whose trading activity in Fund shares is deemedharmful to the Funds.

While the Funds attempt to discourage Frequent Trading, therecan be no guarantee that they will be able to identify investorswho are engaging in Frequent Trading or limit their tradingpractices. Additionally, frequent trades of small amounts may notbe detected. The Funds recognize that it may not always be ableto detect or prevent Frequent Trading or other activity that maydisadvantage the Funds or their shareholders.

A Fund shareholder’s right to purchase shares through anautomatic investment plan or redeem shares in full (or in partthrough a systematic redemption plan) are unaffected by theserestrictions.

EscheatmentIf your account is held directly with a Fund and is later deemed“abandoned” or “unclaimed” under state law, the Fund may berequired to “escheat” or transfer the assets in your account to theapplicable state’s unclaimed property administration. The statemay sell or redeem escheated shares and, if you subsequentlyseek to reclaim your proceeds of liquidation from the state, youmay only be able to recover the amount received when theshares were sold or redeemed. The Fund and the Transfer Agentwill not be liable to shareholders or their representatives for goodfaith compliance with state escheatment laws.

Election under Rule 18f-1The Trust, on behalf of each Fund included in this Prospectus,has made an election pursuant to Rule 18f-1 under the 1940 Actcommitting each such Fund to pay in cash any request forredemption received during any 90-day period of up to the lesserof $250,000 or 1% of the Fund’s net asset value at the beginningof the period. This election is irrevocable without prior approvalby the SEC. Each Fund reserves the right to pay redemptionproceeds in-kind except as described above.

Share Dividends and DistributionsIt is the practice of each Fund to distribute, annually, all netinvestment income received from investments alongside any netrealized capital gains earned through trading activities.

Distributions will be automatically reinvested in Fund sharesunless you submit a request for a cash payment with at least tendays’ prior notice, before the record date for distribution, to theTransfer Agent.

Section 985 of the Code) is not the U.S. dollar, persons investingthrough defined contribution plans and other tax-qualified plans,and persons that hold shares in a Fund as part of a “straddle,”“conversion transaction,” “hedge,” or other integrated investmentstrategy. All such prospective and actual shareholders are urgedto consult their own tax advisers with respect to the U.S. taxtreatment of an investment in shares of a Fund.

The discussion below as it relates to U.S. federal income taxconsequences is based upon the Code and regulations, rulings,and judicial decisions thereunder as of the date hereof. Suchauthorities may be repealed, revoked, or modified (possibly on aretroactive basis) so as to result in U.S. federal income taxconsequences different from those discussed below. The Fundshave not sought an opinion of legal counsel as to any specificU.S. tax matters.

U.S. ShareholdersThe following discussion addresses certain U.S. federal incometax considerations which may be relevant to investors that:

— are citizens or residents of the United States, orcorporations, partnerships, or other entities created ororganized under the laws of the United States or any politicalsubdivision thereof, estates that are subject to United Statesfederal income taxation regardless of the source of theirincome or trusts if (i) a court within the United States is ableto exercise primary supervision over the administration ofthe trust and one or more U.S. persons have the authority tocontrol all substantial decisions of the trust or (ii) the trusthas a valid election in effect under applicable Treasuryregulations to be treated as a United States person; and

— hold, directly or indirectly, shares of a Fund as a capitalasset (each such investor a “U.S. shareholder”).

Tax StatusEach Fund is treated as a separate taxable entity for U.S. federalincome tax purposes.

Each Fund has elected or, in the case of a new Fund, intends toelect to be treated as a regulated investment company underSubchapter M of the Code and intends each year to qualify andbe eligible for treatment as such. In order to qualify and beeligible for treatment as a regulated investment company underSubchapter M of the Code, each Fund must, among other things,derive at least 90% of its gross income each year from certainsources of “qualifying income” and comply with certain assetdiversification and distribution requirements.

So long as a Fund qualifies for treatment as a regulatedinvestment company, the Fund itself generally will not be subjectto U.S. federal income tax to the extent that it distributes to itsshareholders, in a timely manner, dividend, interest and certainother income, its net realized short-term capital gains and its netrealized long-term capital gains.

The remainder of this discussion assumes that each Fund willqualify as a regulated investment company.

Excise TaxEach Fund will be subject to a nondeductible 4% excise tax onthe undistributed amounts, if it fails to distribute in a calendar

year substantially all of its ordinary income for such year andsubstantially all of its capital gain net income for the one yearperiod ending October 31 (or for the one-year period endingDecember 31 if the Fund so elects), plus any retained amountfrom the prior year. Distributions made in January will generallybe deemed to have been paid by such Fund on December 31 ofthe preceding year, if the distribution was declared and payableto shareholders of record on a date in October, November orDecember of that preceding year.

Each Fund intends generally to make distributions sufficient toavoid imposition of the 4% excise tax, although there can be noassurance it will make such distributions.

Personal Holding Company RulesIf a Fund were to be a “personal holding company,” it wouldpotentially need to comply with additional requirements withrespect to its distributions to shareholders in order to avoid afund-level tax under the personal holding company rules.

DistributionsFor U.S. federal income tax purposes, distributions of investmentincome are generally taxable to shareholders subject to tax asordinary income.

Taxes on distributions of capital gains are determined by howlong a Fund owned (or is deemed to have owned) theinvestments that generated them, rather than how long theshareholder has owned its shares.

Distributions of net capital gains from the sale of investmentsthat a Fund owned (or is deemed to have owned) for more thanone year and that are properly reported by a Fund as capital gaindividends will be taxable as long-term capital gains and taxed toindividuals at reduced rates relative to ordinary income.Distributions of gains from the sale of investments that a Fundowned (or is deemed to have owned) for one year or less will betaxable as ordinary income. Distributions of investment incomereported by a Fund as derived from “qualified dividendincome”—as further defined in the SAI—will be taxed in thehands of individuals at the rates applicable to long-term capitalgains provided that holding period and other requirements aremet at both the shareholder and Fund level.

Distributions are taxable to a shareholder (other than a tax-exempt shareholder or a shareholder investing through atax-advantaged arrangement) even if they are paid from incomeor gains earned by a Fund before the shareholder’s investment(and thus were included in the price paid by the shareholder forFund shares). Distributions from a Fund will be taxed asdescribed above whether received in cash or in additionalFund shares.

Notwithstanding the foregoing, each of the Funds may retain(a) investment company taxable income, subject to thedistribution requirements applicable for qualification as aregulated investment company under the Code or (b) net capitalgains and pay a Fund-level tax on any such retained amounts.

Medicare TaxA 3.8% Medicare contribution tax is imposed on the “netinvestment income” of certain individuals, trusts and estates tothe extent their income exceeds certain threshold amounts. Net

investment income generally includes for this purpose dividends,including any capital gain dividends paid by a Fund, and netgains recognized on the sale, exchange, redemption or othertaxable disposition of shares of a Fund.

Sale, Exchange or RedemptionA sale, exchange, or redemption of shares of a Fund, including aredemption in-kind, is a taxable event to the selling, exchanging,or redeeming shareholder. An exchange of a Fund’s shares forshares of another Baillie Gifford fund will be treated as a sale ofthe Fund’s shares. Any gain resulting from a sale, exchange(including an exchange for shares of another Baillie Gifford fund),or redemption of shares in a Fund will generally (except in thecase of a tax-exempt shareholder or a shareholder investingthrough a tax-advantaged arrangement) be subject to federalincome tax at either short-term or long-term capital gain ratesdepending on how long the shareholder has owned the shares.

Foreign Currency and Other Derivative TransactionsA Fund’s transactions in foreign currencies and certain derivativeinstruments, including options, futures contracts, forwardcontracts, swaps and straddles, as well as any of its hedgingtransactions may be subject to special tax rules and may producea difference between the Fund’s book income and taxableincome. The special tax rules to which such transactions aresubject may accelerate income or defer losses of a Fund, orotherwise affect the amount, timing or character of distributionsto shareholders. A difference between a Fund’s book and taxableincome may cause a portion of the Fund’s income distributions toconstitute a return of capital for tax purposes or require the Fundto make distributions exceeding book income to qualify as aregulated investment company.

Debt TransactionsA Fund’s investments in certain debt obligations may cause thatFund to recognize taxable income in excess of the cashgenerated by such obligations. As a result, a Fund could berequired at times to liquidate other investments, including when itis not advantageous to do so, in order to satisfy its distributionrequirements.

Foreign TaxesEach Fund may be subject to foreign withholding and other taxeson income, gains and proceeds derived from foreign investments.Such taxes would reduce the yield on a Fund’s investments.However, as described immediately below, shareholders may beentitled to claim a credit or deduction with respect to their shareof foreign taxes incurred by a Fund.

Foreign Tax Credit or DeductionIf more than 50% of a Fund’s assets at taxable year end consistof the securities of foreign corporations, the Fund may elect topermit shareholders who are U.S. citizens or residents or U.S.corporations to claim a foreign tax credit or deduction (but notboth) on their U.S. income tax returns for their pro-rata portionsof foreign income taxes paid by the Fund. In such case, incomeof a Fund from non-U.S. sources that is distributed to Fundshareholders would be treated as income from non-U.S. sourcesto the shareholders. The amount of foreign income taxes paid bya Fund would be treated as foreign taxes paid directly by Fund

shareholders and, in addition, this amount would be treated asadditional income to Fund shareholders from non-U.S. sourcesregardless of whether the Fund shareholder would be eligible toclaim a foreign tax credit or deduction in respect of those taxes.Shareholders that are not subject to U.S. federal income tax, andthose who invest in a Fund through tax-advantaged accounts(including those who invest through tax-advantaged retirementplans), generally will receive no benefit from any tax credit ordeduction passed through by the Fund. Investors should consulttheir tax advisors for further information relating to the foreign taxcredit and deduction, which are subject to certain restrictions andlimitations (including, with respect to the foreign tax credit, aholding period requirement applied at both the Fund and theshareholder level). Prospective investors should also consult thediscussion in the SAI regarding investment by a Fund insecurities of certain foreign corporations.

Annual Tax ReportsWhere required, the Funds will provide shareholders with federaltax information annually, including information about dividendsand distributions paid during the preceding year.

IRS ReturnsShareholders may be required to file an information return withthe IRS including, but not limited to, if they recognize certainlevels of losses with respect to shares in a Fund ($2 million ormore for an individual shareholder or $10 million or more for acorporate shareholder), or are deemed to have participated in aconfidential transaction involving shares in a Fund.

FinCEN Form 114Shareholders that are U.S. persons and own, directly or indirectly,more than 50% of a Fund could be required to report annuallytheir “financial interest” in the Fund’s “foreign financial accounts,”if any, on FinCEN Form 114, Report of Foreign Bank andFinancial Accounts. Shareholders are urged to consult a taxadvisor regarding the applicability to them of this reportingrequirement.

Backup Withholding TaxA Fund generally is required to apply backup withholding andremit to the U.S. Treasury a percentage of the taxabledistributions and redemption proceeds paid to any individualshareholder who fails to properly furnish the Fund with a correcttaxpayer identification number, who has under-reported dividendor interest income, or who fails to certify to the Fund that he orshe is not subject to such withholding.

Non-U.S. Persons Tax TreatmentFund shareholders who are not U.S. citizens or residents or thatare foreign corporations, partnerships, trusts or estates may besubject to substantially different tax treatment with respect todistributions from the Funds.

HISTORICAL PERFORMANCE

INFORMATION FOR SIMILAR ACCOUNTS

Certain Funds were recently organized and have little or noperformance history of their own that is permitted to be shown inthe “Fund Summary” section of this Prospectus. For some ofthese Funds, the following tables set forth historical performanceinformation for all discretionary accounts, all of which are non-U.S. regulated open-end investment funds or other institutionalaccounts, managed by the Manager and its affiliates that havesubstantially similar investment objectives, policies, strategies,risks and investment restrictions as each listed Fund.

The results presented below may not necessarily equate with thereturn experienced by any particular investor as a result of thetiming of investments and redemptions. In addition, the effect oftaxes on any investor will depend on such person’s tax status,and the results have not been reduced to reflect any income taxthat may have been payable.

Composite Data

For certain Funds, Composite (defined by the Global InvestmentPerformance Standards (“GIPS®”) as an “aggregation of one ormore portfolios managed according to a substantially similarinvestment mandate, objective or strategy”) data is provided toillustrate, with respect to each Fund, the past performance of theManager and its affiliates in managing all substantially similaraccounts as measured against specified market indices.Composite data does not represent the performance of any ofthe Funds. The accounts in each Composite are separate anddistinct from the Fund; the Composite performance is notintended as a substitute for the Fund’s performance and shouldnot be considered a prediction of the future performance of theFund or the Manager. The performance of the accounts in eachComposite may differ, sometimes significantly, from theperformance of the Fund for a variety of reasons, includingdivergences in underlying investments resulting from variousregulatory restrictions specific to mutual funds as well as otherdifferences relating to jurisdiction and/or product design, such asthe applicability of U.S. sanctions and other investmentrestrictions.

The Manager claims compliance with GIPS®. For GIPS®

purposes, the Manager is defined and held out to the public asthe investment management and advisory services provided bythe Manager and Baillie Gifford & Co., its parent entity. Additionalinformation regarding the Composites and the Manager’s policiesfor valuing portfolios, calculating performance, and preparingcompliant presentations are available upon request.

Each Composite’s performance data shown below wascalculated in accordance with recognized industry standards,consistently applied to all time periods. All returns presentedwere calculated on a total return basis and include all dividendsand interest, accrued income and realized and unrealized gainsand losses. All returns reflect the deduction of brokeragecommissions and execution costs paid by the discretionaryinstitutional accounts, without provision for federal or stateincome taxes. “Net of Fees” composite figures are calculated byreducing the gross return by the highest annual management fee

for the composite. Each Composite includes all actualdiscretionary institutional accounts managed by the Manager andits affiliates for at least one full month that have investmentobjectives, policies, strategies and risks substantially similar tothose of the Fund. The Composites may include both tax-exemptand taxable accounts and all reinvestment of earnings. EachComposite’s performance information is calculated on the basisof the returns of underlying accounts expressed in U.S. dollars;to the extent that accounts underlying a Composite aredenominated in currencies other than U.S. dollars. The accountsunderlying a Composite may be denominated in variouscurrencies other than U.S. dollars; the returns of those accountshave been converted to U.S. dollars as of each reference date,prior to factoring those accounts into the Compositeperformance. The performance shown would be different in theabsence of such conversion.

Securities transactions are accounted for on trade date andaccrual accounting is utilized. Cash and equivalents are includedin performance returns.
