The following tables describe the fees and expenses that you will pay when buying, owning, and surrendering theContract. For a complete discussion of Contract fees and expenses, see Contract Fees and Charges.

The first table describes the fees and expenses that you will pay at the time that you buy the Contract, surrenderthe Contract, or transfer cash value between investment options. No state premium taxes are deducted.

Contract Owner Transaction Expenses

Sales Load Imposed on Purchase (as a percentage of purchase payments) 0%

Transfer Charge (after 12 free transfers per Contract Year) $251

Maximum Commuted Value Charge (if surrendered) 2%2

The next table describes the fees and expenses that you will pay periodically during the time that you own theContract, not including Portfolio fees and expenses.

Periodic Fees and Expenses other than Fund Expenses

Mortality and Expense Risk Charge 1.25%

The next table shows the minimum and maximum Total Annual Portfolio Operating Expenses charged by thePortfolios that you pay indirectly during the time you own the Contract. This table shows the range (minimumand maximum) of fees and expenses (including management fees and other expenses) charged by any of thePortfolios, expressed as an annual percentage of average daily net assets. The amounts are based on the arithmeticaverage of expenses paid in the year ended December 31, 2017, for all of the available Portfolios, adjusted to reflectanticipated changes in fees and expenses. With respect to new Portfolios, amounts are based on estimates for thecurrent fiscal year. The amounts shown reflect expenses before any applicable expense reimbursement or fee waiver.

Maximum Minimum

(expenses that are deducted from Fund Assets, including management feesand other expenses)

3.61% 0.25%

Each Subaccount of the Variable Account purchases shares of the corresponding Fund Portfolio at net asset value.The net asset value reflects the investment advisory fees and other expenses that are deducted from the assets of thePortfolio. The advisory fees and other expenses are not fixed or specified under the terms of the Contract, and theymay vary from year to year. More detail concerning the fees and expenses of the Portfolios is contained in theprospectus for the Fund.

If a Portfolio is structured as a “fund of funds,” the Portfolio will indirectly bear its proportionate share of any feesand expenses (like investment advisory fees and operating expenses) of the investment companies in which itinvests. However, Thrivent Financial has contractually agreed, for as long as the current fee structure is in place, towaive an amount equal to any investment advisory fees indirectly incurred by an Asset Allocation Portfolio as aresult of its investment in any other mutual fund for which the Adviser or an affiliate serves as investment adviser,other than Thrivent Cash Management Trust. For a list of the “fund of funds” portfolios available through theContract, see the chart of portfolios available in the prospectus for the Fund.

Examples4

The following two examples are intended to help you compare the cost of investing in the Contract with the costof investing in other variable annuity contracts. These costs include Contract Owner transaction expenses,Contract fees, separate account annual expenses, and Portfolio fees and expenses. The following two examplesassume that you invest $10,000 in the Contract for the time periods indicated and that your investment has a 5%return each year and assumes both the minimum and the maximum fees and expenses of the Portfolios. Althoughyour actual costs may be higher or lower, based on these assumptions, your costs would be:

Example 1: If you select a life income payment option with a 10-year guaranteed Payment

Years

1 3 5 10

If you surrender your Contract at the end of theapplicable time period with

Minimum Portfolio Expenses: $196 $ 448 $ 700 $1,337

Maximum Portfolio Expenses: $577 $1,410 $2,187 $3,908

If you do not surrender your Contract at end of theapplicable time period with

Minimum Portfolio Expenses: $138 $ 412 $ 682 $1,337

Maximum Portfolio Expenses: $467 $1,346 $2,157 $3,908

Example 2: If you select a 20-year fixed period income payment option

Years

1 3 5 10

If you surrender your Contract at the end of theapplicable time period with

Minimum Portfolio Expenses: $ 504 $ 698 $ 875 $1,231

Maximum Portfolio Expenses: $1,149 $1,818 $2,393 $3,450

If you do not surrender your Contract at end of theapplicable time period with

Minimum Portfolio Expenses: $ 134 $ 389 $ 624 $1,108

Maximum Portfolio Expenses: $ 454 $1,273 $1,977 $3,277

Notes to Fee and Expense Tables:1 You are allowed 12 free transfers between the Subaccounts in each Contract Year. Subsequent transfers will incur a $25 transfercharge.2 If you surrender or withdraw from the Contract, we will pay you the commuted value of the future payments for theremaining guaranteed payment period. We calculate the commuted value you receive for the Fixed Account using an interestrate that is currently 0.5% greater than the rate used to determine the Annuity Payments. For variable Subaccounts, we currentlyuse an interest rate that is 0.5% greater than the assumed investment return that you selected. Since we use a higher interest ratein calculating the commuted value, the contract has an indirect surrender charge. Also, the amount that you will receive upon awithdrawal or surrender of the Contract will be less than you would receive had you chosen to continue receiving AnnuityPayments.3 Thrivent Financial has agreed to reimburse certain expenses other than the advisory fees for certain of the Portfolios. Aftertaking these contractual and voluntary arrangements into account, the actual range (minimum and maximum) of totaloperating expenses charged by the Portfolios was between 0.25% to 1.20%. The reimbursements may be discontinued at anytime.4 For both examples, the following assumptions are used: portfolio operating expenses ranging from 3.61% to 0.25%.

investments held, fund expenses, and other factors allcontribute to differences in Portfolio performance. Forall of these reasons, you should expect investmentresults to differ. In particular, certain Portfolios availableonly through the Contract may have names similar toportfolios not available through the Contract. Theperformance of a Portfolio not available through theContract does not indicate performance of the similarlynamed Portfolio available through the Contract.

Before selecting any Subaccount, you shouldcarefully read the accompanying prospectus forthe Fund attached to this prospectus and foundin the back of this book. You shouldperiodically consider your allocation amongSubaccounts in light of current marketconditions and your investment goals, risktolerance and financial circumstances. TheFund prospectus provides more completeinformation about the Portfolios of the Fund inwhich the Subaccounts invest, includinginvestment objectives and policies, risks,charges, and expenses.

Shares of the Fund are sold to other Portfolios of theFund, to other insurance company separate accounts ofours and of our wholly owned subsidiary, Thrivent LifeInsurance Company (“Thrivent Life”), and to otherinsurance company separate accounts not affiliated withus. The Fund may, in the future, create new Portfolios. Itis conceivable that in the future it may bedisadvantageous for both variable annuity separateaccounts and variable life insurance separate accountsand for Thrivent Life and us to invest simultaneously inthe Fund, although we do not foresee any suchdisadvantages to either variable annuity or variable lifeinsurance contract owners. The Fund’s managementintends to monitor events in order to identify anymaterial conflicts between such Contract Owners and todetermine what action, if any, should be taken inresponse. Material conflicts could result from, forexample:

� Changes in state insurance laws;

� Changes in Federal income tax law;

� Changes in the investment management of theFund; or

� Differences in voting instructions between thosegiven by the Contract Owners from the differentseparate accounts.

If we believe the responses of the Fund to any of thoseevents or conflicts insufficiently protects ContractOwners, we may take appropriate action on our own.Such action could include the sale of Fund shares byone or more of the separate accounts, which could haveadverse consequences.

The Fund is a Minnesota corporation registered with theSEC under the 1940 Act as an open-end managementinvestment company (commonly called a “mutualfund”). That registration does not involve supervisionby the SEC of the management or investment practicesor policies of the Fund.

The Variable Account will purchase and redeem sharesfrom the Fund at net asset value. Shares will beredeemed to the extent necessary for us to collectcharges under the Contracts, to make payments uponsurrenders, to provide benefits under the Contracts, orto transfer assets from one Subaccount to another asrequested by Contract Owners. Any dividend or capitalgain distribution received from a Portfolio of the Fundswill be reinvested immediately at net asset value inshares of that Portfolio and retained as assets of thecorresponding Subaccount.

Fixed Account

You may allocate the premiums paid under the Contractand transfers from the Subaccounts to the FixedAccount. Any amounts allocated to the Fixed Accountare invested in our general account assets. Because ofexemptive and exclusionary provisions, interests in theFixed Account have not been registered under theSecurities Act of 1933 (“1933 Act”), and the FixedAccount has not been registered as an investmentcompany under the Investment Company Act of 1940(“1940 Act”). Accordingly neither the Fixed Account,nor any interests therein are generally subject to theprovisions of the 1933 or 1940 Acts. Disclosuresregarding the Fixed Account, however, may be subjectto certain generally applicable provisions of the federalsecurities laws relating to the accuracy andcompleteness of statements in prospectuses. We havebeen advised that the staff of the Securities andExchange Commission has not reviewed disclosurerelating to the Fixed Account.

Contract Owners have no voting rights in the VariableAccount with respect to Fixed Account values.

If our reserves become impaired, youmay be required to make an extra payment. Our Boardof Directors will determine the amount of any extrapayment based on each member’s fair share of thedeficiency. If the payment is not made, it will becharged as a debt against the Contract with an interestrate of 5% per year. You may choose an equivalentreduction in benefits instead of or in combination withthe debt. Any indebtedness and interest charged againstthe Contract, or any agreement for a reduction inbenefits, shall have priority over the interest of anyowner, beneficiary, or collateral assignee under theContract.

Keep in mind that if you designate anotherperson or entity as payee, you may still be responsiblefor any income tax payable on the payments.

In the event the Annuitant(s) dies during theguaranteed payment period, the death proceeds will bepayable to the named beneficiary. We use theAnnuitant’s life to determine the amount and durationof any Annuity Payments.

Under certain circumstances other entities, such astrusts, may purchase Thrivent Financial products but arenot eligible for membership.

Adult and Juvenile Contracts

We issue adult Contracts to applicants who are age 16 orolder who become benefit members of ThriventFinancial.

the Contract becomes a benefit member of ThriventFinancial upon our approval of the membershipapplication.

For the juvenile Contract, a juvenile is named as theAnnuitant and owner of the Contract. However, becauseof age, the juvenile cannot exercise the rights ofownership. Therefore, an adult must apply on behalf ofthe juvenile and retain control over the Contract. Theadult applicant controller exercises certain rights ofownership on behalf of the juvenile Annuitant. Theserights are described in the Contract. The adult controllermay transfer control to another eligible person, butcannot transfer ownership of the Contract.

Transfer of control to the juvenile Annuitant will takeplace at the first Contract Anniversary date followingthe earlier of:

� the Annuitant’s 21st birthday; or

� the Annuitant’s 16th birthday after the adultcontroller transfers control to the Annuitant inwriting; or

� the death of the adult controller after theAnnuitant’s 16th birthday.

If the person who has control of the Contract diesbefore the Annuitant gains control, control will bevested in an eligible person according to our bylaws. Ifwe determine that it is best for the Annuitant, we maytransfer control of the Contract to some other eligibleperson according to our bylaws.

The juvenile Annuitant will become a benefit memberof Thrivent Financial on the first Contract Anniversarydate on or following the juvenile’s 16th birthday.

Beneficiaries

You may name one or more beneficiaries to receive thedeath proceeds payable under the Contract, if any. If nobeneficiary has been named or the beneficiary does not

survive the Annuitant, the death proceeds will be paidto you, if living, otherwise to your estate (in accordancewith applicable state law). Thrivent Financial bylaws listpersons eligible to be beneficiaries. You may designatebeneficiaries as either first, second or third class. Unlessotherwise specified, we will distribute death proceeds inthe following order to beneficiaries:

� equally to the beneficiaries in the first class. If noneare living, then;

� equally to the beneficiaries in the second class. Ifnone are living, then;

� equally to the beneficiaries in the third class.

If a beneficiary dies within 15 days after the death of theAnnuitant, we will consider the beneficiary to have diedbefore the Annuitant for purposes of paying the deathproceeds.

No beneficiary change shall take effect unless receivedby Thrivent Financial at its principal office or corporateheadquarters. When it is received, any change shall takeeffect as of the date the request for beneficiary changewas signed, as long as the request for change was mailedor actually delivered to Thrivent Financial while theinsured was alive. Such beneficiary change shall be nulland void where Thrivent Financial has made a goodfaith payment of the proceeds or has taken other actionbefore receiving the change.

If you elect not to have a guaranteed payment period orall Annuitants live beyond the guaranteed paymentperiod, no death proceeds will be payable.

Assignment of Ownership

The Contract cannot be sold, assigned, discounted, orpledged as collateral for a loan or as surety forperformance of an obligation or for any other purpose.

ANNUITY PAYMENTS••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••

Selecting an Annuity Payment Option

The annuity payment option specifies the type ofannuity to be paid and determines how long theannuity will be paid, the frequency of payment, and theamount of the first Annuity Payment. You must selectthe Annuity Payment option when applying for theContract. You may not change the type of AnnuityPayment option once we issue the Contract.

If you choose a life income payment option, you mustelect to characterize your Contract and its AnnuityPayments as either revocable or irrevocable. (However,some states do not allow the characterization of aContract as revocable.) For all other payment options,your Contract will be revocable. If you elect theirrevocable option, you cannot later change the AnnuityPayments, or receive a withdrawal or surrender from theContract. If you elect the irrevocable option, you cannotlater change to the revocable option once we issue theContract. If your Contract is revocable you can:

� change the duration of the guaranteed paymentperiod (to a shorter period);

� receive withdrawals; and

� surrender the Contract.

If your Contract is revocable and you have chosen a lifeincome payment option, you can later characterize yourContract as irrevocable. However, once you characterizeyour Contract as irrevocable, you cannot later change itto a revocable Contract once the change is made.

If you do not have any other sources of funds foremergencies or other financial needs which may arise,an irrevocable Contract may be inappropriate for you.In addition, even though you can take withdrawalsfrom or surrender a revocable Contract, a revocableContract may be inappropriate for you if you intend ontaking additional withdrawals from or surrendering theContract, particularly in the short term. Withdrawals orsurrenders from a revocable Contract result in theassessment of indirect withdrawal or surrender charges,and the calculation of new commuted values. SeeContract Fees and Charges for more informationregarding the calculation of commuted values and theassessment of indirect withdrawal or surrender charges.

You must also select the Subaccounts and/or the FixedAccount to which we will apply your premium. Wereserve the right to limit the number of allocations tosubaccounts and fixed account. Except as discussed inFree Look Period, the annuity unit value for eachSubaccount selected as of the Valuation Date when wereceive your premium, will be used to calculate thenumber of annuity units which determine your firstvariable Annuity Payment. Your total Annuity Paymentwill be the Fixed Account Annuity Payment, if any, plusthe Variable Account Annuity Payment.

If you do not specify an Annuity Payment option, wewill treat your application as not being in good order. Ifyou do not specify whether or not the Contract and itsAnnuity Payments will be irrevocable or revocable, wewill issue the Contract as revocable.

You must also tell us at time of application whichfinancial institution and account you would like yourpayments sent to or if you wish to receive your paymentby check. If you select a financial institution, we willsend your Annuity Payments via electronic fundstransfer to the financial institution that you request. Ifthe owner of the Contract is not named on the accountat the financial institution receiving the AnnuityPayments, we will require a Medallion SignatureGuarantee.

Annuity Payment Options

Fixed Period Income

Subject to our approval, we make Annuity Payments atregular intervals for a fixed number of payments, not toexceed 30 years. We call this payment period the“guaranteed payment period.” At the end of theguaranteed payment period, all of the AnnuityPayments will have been paid, the commuted value ofthe Contract will be zero, and the Contract willterminate.

Life Income with Guaranteed Payment Period

We make Annuity Payments at regular intervals for thelifetime of the Annuitant. If the Annuitant dies duringthe guaranteed payment period, we will continuepayments to the beneficiary to the end of theguaranteed payment period. You may generally choose aguaranteed payment period of 0 to 30 years at the time

we issue the Contract. The amount of the paymentsdepends upon the sex and age of the Annuitant, at thetime we issue the Contract. If you select a shorterguaranteed payment period, you will receive largerAnnuity Payments. Both the commuted value and deathproceeds, however, will be smaller if the guaranteedpayment period is shorter. If you die after the end of theguaranteed payment period, no death proceeds will bepayable. Also, no surrenders or withdrawals arepermitted after the end of the guaranteed paymentperiod. If you have poor health or have a shortened lifeexpectancy, you may want to consider selecting a longerguaranteed payment period.

Joint and Survivor Life Income with GuaranteedPayment Period

We make Annuity Payments at regular intervals for thelifetime of both Annuitants. The Annuitants will alsoown the Contract as joint owners. For an IRA orqualified plan, the IRA owner or qualified plan willremain the owner. Upon the death of one of theAnnuitants, we will continue payments for the lifetimeof the surviving Annuitant. If both Annuitants dieduring the guaranteed payment period, we willcontinue payments to the beneficiary to the end of thatperiod. You may generally choose a guaranteed paymentperiod of 0 to 30 years at the time of issue. You may alsochoose to have the Annuity Payment reduced after thedeath of the first Annuitant. The Annuity Payment maybe reduced by a factor of 1⁄2, 1⁄3, or 1⁄4. We will reduce thepayments immediately after the later of the first deathof one of the Annuitants and the end of the guaranteedpayment period. A higher reduction amount will resultin a higher payment while both Annuitants are alive.The amount of the payments depends upon the age andsex of the Annuitants at the time of issue.

Annuity Payment Dates

Annuity Payments may be made monthly, quarterly,semi-annually and annually. In addition, payments maybe made annually but paid monthly. Under thispayment option, the Annuity Payment will bedistributed from the variable Subaccounts annually, butwill be placed in the Fixed Account to earn interest. Wewill then make monthly payments from the FixedAccount for the remainder of the year.

You may select the Annuity Payment Date. If you do notselect a payment date, the Annuity Payment Date willbe the same day of the month as the Issue Date. In theevent that you do not select a payment frequency,Annuity Payments will be made monthly. Once youselect the Annuity Payment frequency or the AnnuityPayment Date, neither may be changed.

After the first Annuity Payment, we computesubsequent payments on the date you elect to receiveAnnuity Payments.

Fixed Account Annuity Payments

You may choose to deposit some or none of yourpremium in the Fixed Account portion of the Contract.

Premiums deposited in the Fixed Account will fundguaranteed periodic payments. We will determine theguaranteed Annuity Payment at the time we issue theContract. We may pay more than the guaranteedAnnuity Payment if the investment experience of theFixed Account is more favorable than the guaranteedinterest rate shown in the Contract. We may also paymore than the guaranteed payment if our mortalityexperience or administration expenses are favorable. Wemay change the amount of the Fixed Account AnnuityPayment at any time, but will not pay an amount lowerthan the guaranteed payment.

Premiums placed in the Fixed Account may not betransferred to the Subaccounts.

Variable Annuity Payments

First Variable Annuity Payment

Variable Annuity Payments are periodic payments wemake, the amount of which varies from one AnnuityPayment Date to the next as a function of the netinvestment performance of the Subaccounts youselected. The dollar amount of the first variable AnnuityPayment depends on the Annuity Payment optionchosen, the age of the Annuitant, the gender of theAnnuitant (if applicable), the amount of premiumapplied to purchase the variable Annuity Payments, andan assumed investment return that you select.

Page 24: Single Premium Immediate Variable Annuity · PDF fileSingle Premium Immediate Variable Annuity Issued between 7/26/1999 and 4/29/2016. Prospectuses April 30, 2017 Thrivent Variable

The dollar value of the first variable Annuity Payment isthe sum of the first variable Annuity Paymentsattributable to each Subaccount. The dollar amount ofthe first total Annuity Payment is the sum of the firstvariable Annuity Payment and the Fixed AccountAnnuity Payment.

The first payment is made at the time of issue. Thesecond payment is made on the next Annuity PaymentDate. However, if this results in the second paymentbeing received in the same month as the Issue Date, thesecond payment will be made on the requested date ofthe next Annuity Payment thereafter.

Annuity Units

We initially determine the number of annuity units foreach Subaccount on the Issue Date. We calculate thenumber of annuity units for each Subaccount bydividing the amount of the first variable AnnuityPayment allocable to that Subaccount by the annuityunit value for that Subaccount on the Issue Date. Thenumber of annuity units attributable to eachSubaccount under a Contract remains fixed unless thereis a transfer of annuity units between Subaccounts.

Subsequent Variable Annuity Payments

We determine the dollar amount of each subsequentvariable Annuity Payment attributable to eachSubaccount by multiplying the number of annuity unitsof that Subaccount by the annuity unit value for thatSubaccount for the Valuation Period ending on theAnnuity Payment Date, or during which the AnnuityPayment Date falls. We aggregate the subsequentvariable Annuity Payments for each Subaccount todetermine the variable Annuity Payment. When anAnnuity Payment Date would fall on a day that is not aValuation Date, we calculate the variable AnnuityPayment as of the Valuation Date immediatelypreceding what would have been the Annuity PaymentDate.

The annuity unit value of each Subaccount for anyValuation Period is equal to:

� the annuity unit value for the preceding ValuationPeriod; multiplied by the Subaccount investmentfactor for the current Valuation Period; multipliedby

� a daily discount factor which adjusts the annuityunit value to reflect the assumed investmentreturn. This factor is compounded to reflect thenumber of days in the Valuation Period.

Subaccount Investment Factor

The Subaccount investment factor for any ValuationPeriod is equal to:

� the net asset value of the corresponding Portfolio atthe end of the Valuation Period;

� plus the amount of any dividend, capital gain orother distribution paid by the Portfolio if the“ex-dividend” date occurs during the ValuationPeriod;

� plus or minus any cumulative credit or charge fortaxes reserved from the operation of the portfolio;

� minus the dollar amount of the mortality andexpense risk charge we deduct each day in theValuation Period; and

� divided by the net asset value of the correspondingPortfolio at the beginning of the Valuation Period.

Assumed Investment Return

The annuity unit value for each Subaccount willincrease or decrease from one Annuity Payment Date tothe next in direct proportion to the net investmentreturn of that Subaccount less an adjustment forassumed investment return that you selected. Thepurpose of the adjustment is to ensure the annuity unitvalue only changes when the Subaccount investmentfactor represents a rate of return greater than or lessthan the assumed investment return you selected.

The Contract permits you to select one of three assumedinvestment returns: 3%, 4% or 5%. A higher assumedinvestment return will result in a higher initialpayment, a more slowly rising series of subsequentpayments when actual investment performance(annualized, less deductions and expenses) exceeds theassumed investment return, and a more rapid drop insubsequent payments when actual investmentperformance (annualized, less any deductions andexpenses) is less than the assumed investment return.

For example, if you select a 5% assumed investmentreturn and if the net investment return of theSubaccount is equal to 5% annualized, the variableAnnuity Payment attributable to that Subaccount forthat period will be the same as the previous variableAnnuity Payment. To the extent that the Subaccount’snet investment return exceeds an annualized rate of

return of 5% for a payment period, the variable AnnuityPayment for that period will be more than the previousvariable Annuity Payment. To the extent that theSubaccount’s return is less than an annualized rate of5%, the variable Annuity Payment for that period willbe less than the previous variable Annuity Payment.

TRANSFERS AMONG SUBACCOUNTS AND/OR THE FIXED ACCOUNT••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••

Except for certain restrictions mentioned below, youmay transfer the annuity units of one or moreSubaccounts to one or more other Subaccounts and/orthe Fixed Account. We will process requests for transferthat we receive in good order at our Service Centerbefore 4:00 p.m. Eastern Time as of the close of businesson that Valuation Date. We will process requests wereceive at our Service Center after that time as of theclose of business on the following Valuation Date.

To accomplish a transfer from a Subaccount, we willredeem the annuity units in that Subaccount andreinvest that value in annuity units of the otherSubaccounts and/or the Fixed Account you specified.We impose the following restrictions on transfers:

� You may make up to twelve transfers in eachContract Year. We consider all amounts transferredin the same Valuation Period to be one transfer. Itis not dependent upon the number of originatingor destination Subaccounts.

� You may not transfer from the Fixed Account.

Frequent Trading Policies

Because short-term or frequent transfers, purchases andredemptions of Contract value among Subaccounts poserisks to Contract Owners, we place limits on frequenttrading practices. Such risks include potentiallyimpaired investment performance due to disruption ofportfolio management strategies, increased transactionscosts, and dilution of fund shares (and therefore unitvalues) thereby negatively impacting the performance ofthe corresponding Subaccount.

We have policies and procedures to discourage frequenttransfers of value among Subaccounts. We usereasonable efforts to apply the policies and proceduresuniformly. Several different tactics are used to detectand prevent excessive trading within the Subaccounts.

As described in other sections, we impose a fee if thetransfers made within a given time period exceed amaximum contractual number. See Fee Tables.

We also use a combination of monitoring ContractOwner activity and further restricting certain ContractOwner transfers based on a history of frequent transfersamong Subaccounts. When monitoring Contract Owneractivity, we may consider several factors to evaluatetransfer activity including, but not limited to, theamount and frequency of transfers, the amount of timebetween transfers and trading patterns. In making thisevaluation, we may consider trading in multipleContracts under common ownership or control.

DEATH OF THE OWNER AND/OR ANNUITANT••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••

If you are a joint Annuitant and joint owner, and dieduring the guaranteed payment period, we willcontinue making payments to the surviving jointowner, if any. The surviving joint owner, if any, willbecome the sole Annuitant and owner. If you are a jointAnnuitant and joint owner and die after the end of theguaranteed payment period, we will make payments tothe surviving joint owner, if any, based upon thereduction factor you selected.

If you are the only Annuitant and owner and die duringthe guaranteed payment period, we will continuemaking payments to your beneficiary for the remainderof the guaranteed payment period, if any. Yourbeneficiary will have the option of receiving thecommuted value as a single lump sum in lieu ofcontinuing to receive payments.

If you are the only Annuitant and owner and die afterthe guaranteed payment period, no death proceedswould be payable.

If the owner is an entity, upon the Annuitant’s death,we will continue making payments to the beneficiaryfor the remainder of the guaranteed payment period, ifany. Generally, the owner will also be the beneficiary.The beneficiary will have the option of receiving thecommuted value as a single lump sum in lieu ofcontinuing to receive payments. If the Annuitant diedafter the guaranteed payment period, no death proceedswould be payable.

Upon your death, any remaining Annuity Payments willbe distributed at least as rapidly as under the method ofdistribution being used as of the date of your death.

We will calculate the death proceeds payable as of thedate of death when we receive notice of the death at ourService Center.

We will not recover from the payee or recipient anyAnnuity Payments made on or after the date of deathbut before we receive notice of the death at our ServiceCenter if the Annuity Payment(s) is made within aguaranteed payment period.

Before we can process any death proceeds, we mustreceive at our Service Center:

� proof that the Annuitant or owner died;

� a completed claim form; and

� any other information that we reasonably requireto process the claim.

Upon receipt at our Service Center of instructions inproper form from the beneficiary or owner to resumeAnnuity Payments, we will make any Annuity Paymentsthat had gone unpaid since we received notice of thedeath. We will then resume making Annuity Payments.If we receive instructions to pay the death proceeds in alump sum, we will calculate the commuted value as ofthe date of death, plus interest, minus any AnnuityPayments made before we were notified of the death.

Withdrawal or Surrender Charge

There is no sales charge deducted from your premiumpayment. There also is no direct withdrawal orsurrender charge applicable to the Contract, but if youwithdraw from or surrender the Contract, we will payyou the commuted value of the Contract. We calculatethe commuted value you receive for the Fixed Accountusing an interest rate that is 0.5% higher than the rate

used to determine the Annuity Payments. For variableSubaccounts, we currently use an interest rate that is0.5% greater than the assumed investment return thatyou selected. Since we use a higher interest rate incalculating the commuted value, the Contract has anindirect withdrawal and surrender charge. Also, theamount that you will receive upon a withdrawal orsurrender of the Contract will be less than you wouldhave received had you chosen to continue receivingAnnuity Payments. While there is no direct surrendercharge, the computation of the commuted valueassumes an indirect charge that varies with eachsituation. However, this indirect charge will neverexceed 9%.

Transfer Charge

You may make twelve free transfers in each ContractYear. We will charge you $25 for each subsequenttransfer.

Mortality and Expense Risk Charge

To compensate us for assuming mortality and expenserisks, we deduct a daily mortality and expense riskcharge from the net assets of each Subaccount in theVariable Account. We impose a mortality and expenserisk charge at an annual rate of 1.25% of the averagedaily net assets of such Subaccount in the VariableAccount for the mortality and expense risks it assumesunder the Contract.

In assuming the mortality risk, we incur the risks thatour actuarial estimate of mortality rates may proveerroneous, and Annuitants will live longer thanexpected. If the mortality and expense risk charge andother charges under a Contract are insufficient to cover

the actual mortality costs and administrative expensesincurred by us, we will bear the loss. Conversely, if themortality and expense risk charge proves more thansufficient, we will keep the excess for any propercorporate purpose including, among other things,payment of sales expenses. We expect to make a profitfrom this charge.

Notwithstanding this charge, contract owners may beasked to add money under the Maintenance of Solvencyprovision described in General Information About theContract – Maintenance of Solvency section.

Miscellaneous

Because the Variable Account purchases shares of theFund, the net assets of the Variable Account will reflectthe investment advisory fees or other expenses incurredby the Fund. See Fee and Expense Tables and theaccompanying current prospectus of the Fund.

We reserve the right to impose charges or establishreserves for any federal or local taxes that we incurtoday or may incur in the future and that we deemattributable to the Contract.

Taxes

Currently, we do not assess a charge against the VariableAccount for federal income taxes or state premiumtaxes. We may assess such a charge in the future ifincome or gains within the Variable Account result inany federal income tax liability to us or we becomesubject to state premium taxes. Charges for any othertaxes attributable to the Variable Account may also bemade. See Federal Tax Status.

Gender Neutral Benefits

In 1983, the U.S. Supreme Court held in ArizonaGoverning Committee v. Norris that the application ofsex-distinct actuarial tables to employees based upontheir gender in calculating the amount of retirementbenefits violates Title VII of the Civil Rights Act of 1963.Because of this decision, employer-sponsored retirementplans may not use sex-distinct actuarial annuity rates indetermining benefits.

Generally, annuity payments described in thisProspectus are determined using sex-distinct actuarialtables based on the Annuitant’s gender. However,annuity payments will be based on a gender neutralbasis for the following:

� Contracts used in an employer sponsoredretirement plan;

� Contracts issued in Massachusetts (beginningJanuary 1, 2009); and

� Contracts issued in Montana (beginning October 1,1985).

If thepayment is not made, it will be charged as a debtagainst the Contract with an interest rate of 5% peryear. You may choose an equivalent reduction inbenefits instead of or in combination with the debt. Anyindebtedness and interest charged against the Contract,or any agreement for a reduction in benefits, shall havepriority over the interest of any owner, beneficiary, orcollateral assignee under the Contract.

FEDERAL TAX STATUS••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••

General

The following discussion of the federal income taxtreatment of the Contract is not exhaustive, does notpurport to cover all situations, and is not intended astax advice. The federal income tax treatment of theContract is unclear in certain circumstances, and aqualified tax advisor should always be consulted withregard to the application of law to individualcircumstances. This discussion is based on the Code,Treasury Department regulations, and interpretationsexisting on the date of this Prospectus. Theseauthorities, however, are subject to change by Congress,the Treasury Department, and judicial decisions.

This discussion does not address any federal estate orgift tax consequences, or any state or local taxconsequences, associated with the Contract. In addition,we make no guarantee regarding any tax treatment—federal, state, or local—of any Contract or anytransaction involving a Contract.

Tax Status of the Variable Account

The Variable Account is not separately taxed as a“regulated investment company” under the Code, butrather is treated as our separate account. Under currentlaw, both the investment income and realized capitalgains of the Variable Account (i.e., the income and

capital gains distributed to the Variable Account by theFund) are reinvested without taxation to us. However,we reserve the right in the future to make a chargeagainst the Variable Account or the Contract for anyfederal, state, or local income taxes that we incur anddetermine to be attributable to the Variable Account orthe Contract.

Taxation of Annuities in General

The following discussion assumes that the Contract isnot used in connection with a Qualified Plan.

Tax Treatment as an Annuity

Under current law, a Contract is eligible to be taxed asan annuity contract as described below only if certainrequirements are met. These requirements are: (1) theinvestments of the Variable Account are “adequatelydiversified” in accordance with Treasury Departmentregulations; (2) the Company, rather than the ContractOwner, is considered the owner of the assets of theVariable Account for federal income tax purposes; and(3) the Contract Owner is an individual, an individual istreated as the Contract Owner for tax purposes, oranother exception in the tax law (such as the exceptionfor an “immediate annuity”) applies.

Page 33: Single Premium Immediate Variable Annuity · PDF fileSingle Premium Immediate Variable Annuity Issued between 7/26/1999 and 4/29/2016. Prospectuses April 30, 2017 Thrivent Variable

Diversification Requirements. The Code andTreasury Department regulations prescribe the mannerin which the investments of a segregated asset account,such as the Variable Account, are to be “adequatelydiversified.” If the Variable Account fails to comply withthese rules, the Contract will not be treated as anannuity Contract for federal income tax purposes, withthe result that the contract owner may be subject toincome tax treatment that is more adverse thandescribed below. We expect that the Variable Account,through the Fund, will comply with these rules.

Ownership Treatment. In certain circumstances,variable annuity contract owners may be considered theowners, for federal income tax purposes, of the assets ofa segregated asset account used to support theirContracts. In those circumstances, the account’s incomeand gains would be currently includible in the contractowners’ gross income. The Internal Revenue Service (the“IRS”) has stated in published rulings that a variablecontract owner will be considered the owner of theassets of a segregated asset account if the ownerpossesses incidents of ownership in those assets, such asthe ability to exercise investment control over theassets.

The ownership rights under the Contract are similar to,but different in certain respects from, the ownershiprights described in IRS rulings in which the contractowners were determined not to be the owners of theassets of a segregated asset account. For example, thecontract owner has the choice of more investmentoptions to which to allocate the single premiumpayment and to reallocate annuity unit values thanwere addressed in those rulings. These differences couldresult in the contract owner being treated as the ownerof all or a portion of the assets of the Variable Accountand thus subject to current taxation on the income andgains from those assets. In addition, we do not knowwhat standards will be set forth in any furtherregulations or rulings which the Treasury Department orthe IRS may issue. We therefore reserve the right tomodify the Contract as necessary to attempt to preventcontract owners from being considered the owners ofthe assets of the Variable Account. However, there is noassurance that such efforts would be successful.

Contracts Not Owned by Individuals. As a generalrule, Contracts held by “nonnatural persons” such as acorporation, trust, or other similar entity are not treatedas annuity contracts for federal tax purposes. Theincome on such Contracts (as defined in the tax law) istaxed as ordinary income that is received or accrued bythe Contract Owner during the taxable year. However,this rule generally will not apply to a Contract held by atrust or other entity which holds the Contract as anagent for a natural person. In addition, this rule will notapply to a Contract purchased with a single premiumpayment when the annuity starting date is no later thanone year from the purchase of the Contract andsubstantially equal periodic payments are made, not lessfrequently than annually, during the annuity incomeperiod. The rule also will not apply to: (1) a Contractacquired by the estate of a decedent by reason of thedeath of the decedent; (2) Contracts used in connectionwith certain Qualified Plans; (3) Contracts purchased byemployers upon the termination of certain QualifiedPlans; and (4) certain Contracts used in connection withstructured settlement agreements.

Distribution Requirements. The Code requires thatnonqualified Contracts contain specific provisions fordistribution of proceeds upon the death of any owner.In order to be treated as an annuity Contract for federalincome tax purposes, the Code requires that suchContracts provide that if any owner dies on or after theannuity commencement date and before the entireinterest in the Contract has been distributed, theremaining portion must be distributed at least as rapidlyas under the method in effect on such owner’s death.Under the Contract, the beneficiary is the designatedbeneficiary of an owner/Annuitant and the successorowner is the designated beneficiary of an owner who isnot the Annuitant. If any owner is not a natural person,then for purposes of these distribution requirements,the primary Annuitant shall be treated as an owner andany death or change of such primary Annuitant shall betreated as the death of an owner. The nonqualifiedContracts contain provisions intended to comply withthese requirements of the Code.

The remainder of this discussion assumes that theContract will be treated as an annuity contract forfederal income tax purposes.

Taxation of Annuity Income Payments

Normally, the portion of each annuity income paymentincludible in income for federal tax purposes is theexcess of the payment over an exclusion amount. In thecase of variable income payments, this exclusionamount is the investment in the Contract (definedabove) allocated to the Variable Account whenpayments begin, adjusted for any period certain orrefund feature, divided by the number of paymentsexpected. In the case of fixed income payments, theexclusion amount is determined by multiplying (1) thepayment, by (2) the ratio of the investment in theContract allocated to our Fixed Account, adjusted forany period certain or refund feature, to the totalexpected amount of annuity income payments. For thispurpose, the expected number or amount of annuityincome payments is determined by TreasuryDepartment regulations which take into account theAnnuitant’s life expectancy and the form of annuitybenefit selected. Also, the investment in the contract atany time equals the single premium paid for theContract less any amounts received from the Contractup to that time which were excludable from income.

Once the total amount of the investment in theContract is excluded using the above formulas, annuityincome payments will be fully taxable. All amountsincludible in income with respect to the Contract aretaxed as ordinary income; no amounts are taxed at thelower rates currently applicable to long-term capitalgains and corporate dividends. If annuity incomepayments cease because of the death of the Annuitantand before the total amount of the investment in theContract is recovered, the unrecovered amountgenerally will be allowed as a deduction.

Income from annuities will be subject to the MedicareTax on Investment Income. This tax will be imposed onindividuals with a modified adjusted gross income(MAGI) of more than $200,000 and joint filers with anMAGI of more than $250,000. Generally, the tax ratewill be 3.8% of the lesser of the net investment incomeor the amount the MAGI exceeds the threshold amount.

Taxation of Withdrawals and Surrenders

In the case of a withdrawal, the amount received may beincludible in income for federal tax purposes in wholeor part. While the amount so includible is not entirelyclear, it may equal the amount by which the commutedvalue of the Contract before the withdrawal exceeds theinvestment in the contract (defined above). In the caseof a surrender, the amount received is includible inincome to the extent that it exceeds the investment inthe contract.

Tax Treatment of Life Income with GuaranteedPayment Period After Annuitant’s Death

Where a guaranteed payment period exists under a lifeincome option and the Annuitant dies before the end ofthat period, payments made to the beneficiary for theremainder of that period are includible in income asfollows: (1) if received as the commuted value in a lumpsum, the payment is includible to the extent that itexceeds the unrecovered investment in the contract; or(2) if distributed in accordance with the existingannuity income option, they are fully excluded fromincome until the remaining investment in the contractis deemed to be recovered, and all payments thereafterare fully includible in income.

Penalty Tax on Premature Distributions

Technically, the amount of any payment from theContract that is includible in income is subject to a 10%penalty tax. However, this penalty tax does not apply toany payment: (1) received on or after the ContractOwner attains age 591⁄2; (2) attributable to the ContractOwner’s becoming disabled (as defined in the tax law);(3) made on or after the death of the Contract Owneror, if the Contract Owner is not an individual, on orafter the death of the primary annuitant (as defined inthe tax law); (4) that is part of a series of substantiallyequal periodic payments, not less frequently thanannually, for the life or life expectancy of the ContractOwner or the joint lives or joint life expectancies of theContract Owner and a designated beneficiary (asdefined in the tax law); or, (5) made under a Contractpurchased with a single premium payment when theannuity starting date is no later than one year from thepurchase of the Contract and substantially equalperiodic payments are made, not less frequently thanannually, during the annuity period.

Exchanges of Annuity Contracts

We may issue the Contract in exchange for all or part ofanother annuity contract. Such an exchange will beincome tax free if certain requirements are satisfied (a1035 Exchange). If the exchange is tax free, theinvestment in the Contract immediately after theexchange will generally be the same as that of theannuity contract exchanged, increased by anyadditional premium payment made as part of theexchange. You should consult your tax advisor inconnection with an exchange of all or part of anannuity contract for the Contract.

Qualified Plans

The Contracts also are designed for use with severaltypes of Qualified Plans. Participants under suchQualified Plans as well as Contract Owners, Annuitants,and beneficiaries are cautioned that the rights of anyperson to any benefits under such Qualified Plans maybe subject to the terms and conditions of the plansthemselves regardless of the terms and conditions of theContracts issued in connection with them. Those whointend to use the Contract in connection with QualifiedPlans should seek competent advice.

The tax rules applicable to Qualified Plans, and to aContract when used in connection with a QualifiedPlan, vary according to the type of plan and the termsand conditions of the plan itself, and they takeprecedence over the general annuity tax rules describedabove. For example, for annuity income payments,withdrawals, and surrenders under Contracts used inQualified Plans, there may be no “investment in thecontract,” with the result that the total amount receivedmay be includible in income. The includible amount istaxed at ordinary income tax rates, and a 10% penaltytax also may apply. Exceptions to this penalty tax varydepending on the type of Qualified Plan involved; inthe case of an Individual Retirement Annuity (discussedbelow), exceptions comparable to those described aboveare available.

The following briefly describes certain types of QualifiedPlans in connection with which we may issue aContract.

Individual Retirement Accounts and Annuities.Section 408 of the Code permits eligible individuals tocontribute to an Individual Retirement Account or anIndividual Retirement Annuity (collectively known asan “IRA”). IRAs are subject to limits on the amountsthat may be contributed and deducted, on the personswho may be eligible to do so, and on the time whendistributions may commence. Also, subject to certainrequirements discussed below, you may “roll over”distributions from certain Qualified Plans on atax-deferred basis into an IRA.

Roth IRAs. Section 408A of the Code permits eligibleindividuals to contribute to a type of IRA known as a“Roth IRA.” Roth IRAs are generally subject to the samerules as non-Roth IRAs, but differ in several respects.Among the differences is that, although contributionsto a Roth IRA are not deductible, “qualifieddistributions” (those that satisfy certain waiting and userequirements) from a Roth IRA will be excludable fromincome. Subject to certain restrictions, a distributionfrom an eligible employer-sponsored qualified plan maybe directly moved to a Roth IRA. This movement iscalled a “qualified rollover contribution.”

Section 403(b) Plans. Section 403(b) of the Codepermits public school employees and employees ofcertain types of charitable, educational, and scientificorganizations to have their employers purchase annuityContracts for them and, subject to certain limitations,to exclude the amount of premium payments fromincome for federal tax purposes. Subject to planprovisions, distributions from a Contract purchasedunder section 403(b) may be paid only when theemployee reaches age 591⁄2, separates from service, dies,or becomes disabled, the 403(b) plan terminates, or inthe case of financial hardship. As a result, the ContractOwner will not be entitled to exercise withdrawal orsurrender rights under the Contract unless one of theabove conditions is satisfied. For contracts maintainedpursuant to an employer sponsored 403(b) plan, we mayrequire the employer’s signature to process any requestsfor withdrawal, surrender, rollover or transfers toanother contract.

Direct Rollovers

If your Contract is purchased under section 403(b) ofthe Code or is used in connection with certain otherQualified Plans, any “eligible rollover distribution” fromthe Contract will be subject to direct rollover andmandatory withholding requirements. An eligiblerollover distribution generally is any taxabledistribution from certain Qualified Plans (includingfrom a Contract purchased under section 403(b))excluding amounts such as minimum distributionsrequired under the Code. Under these requirements,federal income tax equal to 20% of the eligible rolloverdistribution will be withheld from the amount of thedistribution. Unlike withholding on certain otheramounts distributed from the Contract, discussed below,the Owner cannot elect out of withholding with respectto an eligible rollover distribution. However, this 20%withholding will not apply if the distribution is directlyrolled over to an IRA or to another eligible retirementplan.

Federal Income Tax Withholding

We will withhold and remit to the federal government apart of the taxable portion of each distribution madeunder a Contract unless the payee notifies us at orbefore the time of the distribution that he or she electsnot to have any amounts withheld. In certaincircumstances, we may be required to withhold tax. Thewithholding rates applicable to the taxable portion ofannuity income payments (other than eligible rolloverdistributions made in connection with Qualified Plans)are the same as the withholding rates generallyapplicable to payments of wages. Further, a 10%withholding rate applies to the taxable portion ofnon-periodic payments (including withdrawals andsurrenders), and as discussed above, the withholdingrate applicable to eligible rollover distributions is 20%.Whether or not federal income tax is withheld, theContract Owner (or other applicable taxpayer) remainsliable for payment of federal income tax on Contractdistributions.

Total Annual Portfolio Operating Expenses 0.97%

Less Fee Waivers and/or ExpenseReimbursements1 0.21%

Total Annual Portfolio Operating Expenses AfterFee Waivers and/or Expense Reimbursements 0.76%

1 The Adviser has contractually agreed, for as long as the current feestructure is in place and through at least April 30, 2019, to waive anamount equal to any investment advisory fees indirectly incurredby the Portfolio as a result of its investment in any other mutualfund for which the Adviser or an affiliate serves as investmentadviser, other than Thrivent Cash Management Trust. Thiscontractual provision may be terminated upon the mutualagreement between the Independent Directors of the Portfolio andthe Adviser.

EXAMPLE This example is intended to help youcompare the cost of investing in the Portfolio with thecost of investing in other mutual funds. The Portfolio isan investment option for variable contracts, and theexample does not include charges imposed by variablecontracts. If variable contract charges were imposed,your expenses would be higher than those shown. Theexample assumes that you invest $10,000 in thePortfolio for the time periods indicated and thenredeem all of your shares at the end of those periods. Inaddition, the example for the 1 Year period reflects theeffect of the contractual fee waiver and/or expense

reimbursement. The example also assumes that yourinvestment has a 5% return each year, and that thePortfolio’s operating expenses remain the same.Although your actual cost may be higher or lower, basedon the foregoing assumptions, your cost would be:

1 Year 3 Years 5 Years 10 Years

Thrivent AggressiveAllocation Portfolio $78 $288 $516 $1,171

Portfolio TurnoverThe Portfolio pays transaction costs, such ascommissions, when it buys and sells securities (or “turnsover” its portfolio). A higher portfolio turnover rate mayindicate higher transaction costs and may result inhigher taxes when Portfolio shares are held in a taxableaccount. These costs, which are not reflected in annualfund operating expenses or in the example, affect thePortfolio’s performance. During the most recent fiscalyear, the Portfolio’s portfolio turnover rate was 63% ofthe average value of its portfolio.

Principal StrategiesThe Portfolio pursues its objective by investing in acombination of other funds managed by the Adviser oran affiliate and directly held financial instruments. ThePortfolio uses a prescribed asset allocation strategyinvolving a two-step process that is designed to achievea desired risk tolerance generally aligned with its peergroup as published by Lipper, Inc. The first step is theconstruction of a model for the allocation of thePortfolio’s assets across broad asset categories (namely,equity securities and debt securities). The second stepinvolves the determination of sub-classes within thebroad asset categories and target weightings (i.e., whatthe Adviser determines is the strategic allocation) forthese sub-classes. Sub-classes may be based on marketcapitalization, investment style (such as growth orvalue), or economic sector for equity securities.Sub-classes for debt securities may be based on maturity,duration, security type or credit rating (high yield—commonly known as “junk bonds”—or investmentgrade) and may include leveraged loans, which aresenior secured loans that are made by banks or otherlending institutions to companies that are rated belowinvestment grade.

The use of target weightings for various sub-classeswithin broad asset categories is intended as a multi-styleapproach to reduce the risk of investing in securitieshaving common characteristics. The Portfolio may buyand sell futures contracts to either hedge its exposure orobtain exposure to certain investments. The Portfoliomay also enter into credit default swap agreements on

security indexes. The Portfolio may enter intostandardized derivatives contracts traded on domestic orforeign securities exchanges, boards of trade, or similarentities, and non-standardized derivatives contractstraded in the over-the-counter market.

Under normal circumstances, the Portfolio invests inthe following broad asset classes within the rangesgiven:

The Portfolio’s actual holdings in each broad assetcategory may be outside the applicable allocation rangefrom time to time due to differing investmentperformance among asset categories. The Adviser willrebalance the Portfolio at least annually so that itsholdings are within the ranges for the broad assetcategories.

The Portfolio also pursues its investment strategy byinvesting in other mutual funds, including fundsmanaged by the Adviser or an affiliate. The names ofthe funds managed by the Adviser or an affiliate whichare currently available for investment by the Portfolioare shown in the list below.

Principal RisksThe Portfolio is subject to the following principalinvestment risks. Shares of the Portfolio will rise and fallin value and there is a risk that you could lose moneyby investing in the Portfolio. The Portfolio cannot becertain that it will achieve its investment objective.

Allocation Risk. The Portfolio’s investmentperformance depends upon how its assets are allocatedacross broad asset categories and applicable sub-classeswithin such categories. Some broad asset categories andsub-classes may perform below expectations or thesecurities markets generally over short and extendedperiods. Underperformance in the equity markets wouldhave a material adverse effect on the Portfolio’s totalreturn given its significant allocation to equitysecurities. Therefore, a principal risk of investing in thePortfolio is that the allocation strategies used and theallocation decisions made will not produce the desiredresults.

Credit Risk. Credit risk is the risk that an issuer of adebt security to which the Portfolio is exposed may nolonger be able or willing to pay its debt. As a result ofsuch an event, the debt security may decline in priceand affect the value of the Portfolio.

Derivatives Risk. The use of derivatives (such asfutures and credit default swaps) involves additionalrisks and transaction costs which could leave thePortfolio in a worse position than if it had not usedthese instruments. The use of derivatives can lead tolosses because of adverse movements in the price orvalue of the underlying asset, index or rate, which maybe magnified by certain features of the contract.Changes in the value of the derivative may not correlateas intended with the underlying asset, rate or index, andthe Portfolio could lose much more than the originalamount invested. Derivatives can be highly volatile,illiquid and difficult to value. Certain derivatives mayalso be subject to counterparty risk, which is that theother party in the transaction will not fulfill itscontractual obligations due to its financial condition,market events, or other reasons.

Foreign Securities Risk. Foreign securities aregenerally more volatile than their domesticcounterparts, in part because of higher political andeconomic risks, lack of reliable information andfluctuations in currency exchange rates. Foreignsecurities may also be more difficult to resell thancomparable U.S. securities because the markets forforeign securities are often less liquid. Even when aforeign security increases in price in its local currency,

the appreciation may be diluted by adverse changes inexchange rates when the security’s value is converted toU.S. dollars. Foreign withholding taxes also may applyand errors and delays may occur in the settlementprocess for foreign securities. All of these risks may beheightened for securities of issuers located in, or withsignificant operations in, emerging market countries.

Growth Investing Risk. Growth style investingincludes the risk of investing in securities whose priceshistorically have been more volatile than othersecurities, especially over the short term. Growth stockprices reflect projections of future earnings or revenuesand, if a company’s earnings or revenues fall short ofexpectations, its stock price may fall dramatically.

High Yield Risk. High yield securities – commonlyknown as “junk bonds” – to which the Portfolio isexposed are considered predominantly speculative withrespect to the issuer’s continuing ability to makeprincipal and interest payments. If the issuer of thesecurity is in default with respect to interest or principalpayments, the value of the Portfolio may be negativelyaffected.

Interest Rate Risk. Interest rate risk is the risk thatprices of debt securities decline in value when interestrates rise for debt securities that pay a fixed rate ofinterest. Debt securities with longer durations (ameasure of price sensitivity of a bond or bond fund tochanges in interest rates) or maturities (i.e., the amountof time until a bond’s issuer must pay its principal orface value) tend to be more sensitive to changes ininterest rates than debt securities with shorter durationsor maturities. Changes by the Federal Reserve tomonetary policies could affect interest rates and thevalue of some securities.

Investment Adviser Risk. The Portfolio is activelymanaged and the success of its investment strategydepends significantly on the skills of the Adviser inassessing the potential of the investments in which thePortfolio invests. This assessment of investments mayprove incorrect, resulting in losses or poor performance,even in rising markets.

Issuer Risk. Issuer risk is the possibility that factorsspecific to a company to which the Portfolio is exposedwill affect the market prices of the company’s securitiesand therefore the value of the Portfolio. Some factorsaffecting the performance of a company includedemand for the company’s products or services, thequality of management of the company and brandrecognition and loyalty. Common stock of a company issubordinate to other securities issued by the company.

Large Cap Risk. Large-sized companies may be unableto respond quickly to new competitive challenges suchas changes in technology. They may also not be able toattain the high growth rate of successful smaller

companies, especially during extended periods ofeconomic expansion.

Leveraged Loan Risk. Leveraged loans (also known asbank loans) are subject to the risks typically associatedwith debt securities. In addition, leveraged loans, whichtypically hold a senior position in the capital structureof a borrower, are subject to the risk that a court couldsubordinate such loans to presently existing or futureindebtedness or take other action detrimental to theholders of leveraged loans. Leveraged loans are alsosubject to the risk that the value of the collateral, if any,securing a loan may decline, be insufficient to meet theobligations of the borrower, or be difficult to liquidate.Some leveraged loans are not as easily purchased or soldas publicly-traded securities and others are illiquid,which may make it more difficult for the Portfolio tovalue them or dispose of them at an acceptable price.Below investment-grade leveraged loans are typicallymore credit sensitive. In the event of fraud ormisrepresentation, the Portfolio may not be protectedunder federal securities laws with respect to leveragedloans that may not be in the form of “securities.” Thesettlement period for some leveraged loans may be morethan seven days.

Liquidity Risk. Liquidity is the ability to sell a securityrelatively quickly for a price that most closely reflectsthe actual value of the security. Dealer inventories ofbonds are at or near historic lows in relation to marketsize, which has the potential to decrease liquidity andincrease price volatility in the fixed income markets,particularly during periods of economic or market stress.As a result of this decreased liquidity, the Adviser mayhave to accept a lower price to sell a security, sell othersecurities to raise cash, or give up an investmentopportunity, any of which could have a negative effecton performance.

Market Risk. Over time, securities markets generallytend to move in cycles with periods when securityprices rise and periods when security prices decline. Thevalue of the Portfolio’s investments may move withthese cycles and, in some instances, increase or decreasemore than the applicable market(s) as measured by thePortfolio’s benchmark index(es). The securities marketsmay also decline because of factors that affect aparticular industry.

Non-Diversified Risk. The Portfolio is not“diversified” within the meaning of the 1940 Act. Thatmeans the Portfolio may invest a greater percentage ofits assets in the securities of any single issuer comparedto other funds. A non-diversified portfolio is generallymore susceptible than a diversified portfolio to the riskthat events or developments affecting a particular issueror industry will significantly affect the Portfolio’sperformance.

Other Funds Risk. The performance of the Portfolio isdependent, in part, upon the performance of otherfunds manged by the Adviser or an affiliate (“OtherFunds”) in which the Portfolio invests. As a result, thePortfolio is subject to the same risks as those faced bythe Other Funds.

Small and Mid Cap Risk. Small- and medium-sizedcompanies often have greater price volatility, lowertrading volumes, and less liquidity than larger, moreestablished companies. These companies tend to havesmaller revenues, narrower product lines, lessmanagement depth and experience, smaller shares oftheir product or service markets, fewer financialresources, and less competitive strength than largercompanies.

Value Investing Risk. Value style investing includesthe risk that stocks of undervalued companies may notrise as quickly as anticipated if the market doesn’trecognize their intrinsic value or if value stocks are outof favor.

Volatility Risk. Volatility risk is the risk that certaintypes of securities shift in and out of favor dependingon market and economic conditions as well as investorsentiment. From time to time, equity investments mayfall out of favor as compared to investments in debtsecurities, and vice versa. Small, less seasonedcompanies and medium-size companies often havegreater price volatility, lower trading volume, and lessliquidity than larger, more-established companies.

Thrivent Balanced Income Plus PortfolioInvestment ObjectiveThrivent Balanced Income Plus Portfolio (the�Portfolio�) seeks long-term total return through abalance between income and the potential forlong-term capital growth.

Fees and ExpensesThis table describes the fees and expenses that you maypay if you buy and hold shares of Thrivent BalancedIncome Plus Portfolio. If you own a variable annuitycontract or variable life insurance contract, you willhave additional expenses including mortality andexpense risk charges. Please refer to the prospectus foryour variable contract for additional information aboutcharges for those contracts.

SHAREHOLDER FEES(fees paid directly from your investment)

Maximum Sales Charge (load) Imposed OnPurchases (as a percentage of offering price) N/A

Maximum Deferred Sales Charge (load) (as apercentage of the net asset value at time ofpurchase or redemption, whichever is lower) N/A

Management Fees 0.55%

Other Expenses 0.10%

Acquired Fund Fees and Expenses 0.03%

EXAMPLE This example is intended to help youcompare the cost of investing in the Portfolio with thecost of investing in other mutual funds. The Portfolio isan investment option for variable contracts, and theexample does not include charges imposed by variablecontracts. If variable contract charges were imposed,your expenses would be higher than those shown. Theexample assumes that you invest $10,000 in thePortfolio for the time periods indicated and thenredeem all of your shares at the end of those periods.The example also assumes that your investment has a5% return each year, and that the Portfolio’s operatingexpenses remain the same.

Thrivent BalancedIncome Plus Portfolio $69 $218 $379 $847

Portfolio TurnoverThe Portfolio pays transaction costs, such ascommissions, when it buys and sells securities (or “turnsover” its portfolio). A higher portfolio turnover rate mayindicate higher transaction costs and may result inhigher taxes when Portfolio shares are held in a taxableaccount. These costs, which are not reflected in annualfund operating expenses or in the example, affect thePortfolio’s performance. During the most recent fiscalyear, the Portfolio’s portfolio turnover rate was 151% ofthe average value of its portfolio.

Principal StrategiesUnder normal circumstances, the Portfolio invests in acombination of equity securities and debt securitieswithin the ranges shown in the following table:

Broad Asset CategoryTarget

AllocationAllocation

Range

Equity Securities . . . . . . . . . . . . . . . . . . . . . . . 50% 25-75%Debt Securities. . . . . . . . . . . . . . . . . . . . . . . . . 50% 25-75%

The equity securities in which the Portfolio invests areprimarily income-producing and may include commonstock, preferred stock, securities convertible intocommon stock, or securities or other instruments theprice of which is linked to the value of common stock.Under normal circumstances, the Portfolio intends toinvest in real estate investment trusts (“REITs”).

The debt securities in which the Portfolio invests maybe of any maturity or credit quality, including highyield, high risk bonds, notes, debentures and other debtobligations commonly known as “junk bonds.” At thetime of purchase, these high-yield securities are ratedwithin or below the “BB” major rating category by S&Por the “Ba” major rating category by Moody’s or areunrated but considered to be of comparable quality bythe Adviser. The Portfolio may also invest in leveragedloans, which are senior secured loans that are made bybanks or other lending institutions to companies thatare rated below investment grade. In addition, thePortfolio may invest in investment-grade corporatebonds, asset-backed securities, mortgage-backedsecurities (including commercially backed ones),convertible bonds, and sovereign and emerging marketdebt (both U.S. dollar and non-U.S. dollardenominated).

The Portfolio may utilize derivatives (such as futuresand swaps) for investment exposure or hedgingpurposes, including credit default swap agreements onsecurity indexes. The Portfolio may enter intostandardized derivatives contracts traded on domestic orforeign securities exchanges, boards of trade, or similar

entities, and non-standardized derivatives contractstraded in the over-the-counter market.

The Portfolio may invest in foreign securities, includingthose of issuers in emerging markets. An “emergingmarket” country is any country determined by theAdviser to have an emerging market economy,considering factors such as the country’s credit rating,its political and economic stability and the developmentof its financial and capital markets.

The Portfolio may invest in exchange-traded funds(“ETFs”), which are investment companies generallydesigned to track the performance of a securities orother index or benchmark.

The Portfolio may also pursue its investment strategy byinvesting in other mutual funds, including fundsmanaged by the Adviser or an affiliate.

The Adviser uses fundamental, quantitative andtechnical investment research techniques to determinewhat to buy and sell. Fundamental techniques assess asecurity’s value based on an issuer’s financial profile,management, and business prospects while quantitativeand technical techniques involve a more data-orientedanalysis of financial information, market trends andprice movements.

Principal RisksThe Portfolio is subject to the following principalinvestment risks. Shares of the Portfolio will rise and fallin value and there is a risk that you could lose moneyby investing in the Portfolio. The Portfolio cannot becertain that it will achieve its investment objective.

Allocation Risk. The Portfolio’s investmentperformance depends upon how its assets are allocatedacross broad asset categories and applicable sub-classeswithin such categories. Some broad asset categories andsub-classes may perform below expectations or thesecurities markets generally over short and extendedperiods. Underperformance in the equity markets ordebt markets would have a material adverse effect onthe Portfolio’s total return given its significantallocation to both equity securities and debt securities.Therefore, a principal risk of investing in the Portfolio isthat the allocation strategies used and the allocationdecisions made will not produce the desired results.

Convertible Securities Risk. Convertible securities aresubject to the usual risks associated with debt securities,such as interest rate risk and credit risk. Convertiblesecurities also react to changes in the value of thecommon stock into which they convert, and are thussubject to market risk. The Portfolio may also be forcedto convert a convertible security at an inopportunetime, which may decrease the Portfolio’s return.

Credit Risk. Credit risk is the risk that an issuer of adebt security to which the Portfolio is exposed may no

longer be able or willing to pay its debt. As a result ofsuch an event, the debt security may decline in priceand affect the value of the Portfolio.

Derivatives Risk. The use of derivatives (such asfutures and credit default swaps) involves additionalrisks and transaction costs which could leave thePortfolio in a worse position than if it had not usedthese instruments. The use of derivatives can lead tolosses because of adverse movements in the price orvalue of the underlying asset, index or rate, which maybe magnified by certain features of the contract.Changes in the value of the derivative may not correlateas intended with the underlying asset, rate or index, andthe Portfolio could lose much more than the originalamount invested. Derivatives can be highly volatile,illiquid and difficult to value. Certain derivatives mayalso be subject to counterparty risk, which is that theother party in the transaction will not fulfill itscontractual obligations due to its financial condition,market events, or other reasons.

Emerging Markets Risk. The economic and politicalstructures of developing countries, in most cases, do notcompare favorably with the U.S. or other developedcountries in terms of wealth and stability, and theirfinancial markets often lack liquidity. Portfolioperformance will likely be negatively affected byportfolio exposure to countries in the midst of, amongother things, hyperinflation, currency devaluation,trade disagreements, sudden political upheaval, orinterventionist government policies. Significant buyingor selling actions by a few major investors may alsoheighten the volatility of emerging markets. Thesefactors make investing in emerging market countriessignificantly riskier than in other countries, and eventsin any one country could cause the Portfolio’s shareprice to decline.

ETF Risk. An ETF is subject to the risks of theunderlying investments that it holds. In addition, forindex-based ETFs, the performance of an ETF maydiverge from the performance of such index (commonlyknown as tracking error). ETFs are subject to fees andexpenses (like management fees and operatingexpenses) that do not apply to an index, and thePortfolio will indirectly bear its proportionate share ofany such fees and expenses paid by the ETFs in which itinvests.

Foreign Securities Risk. Foreign securities aregenerally more volatile than their domesticcounterparts, in part because of higher political andeconomic risks, lack of reliable information andfluctuations in currency exchange rates. Foreignsecurities may also be more difficult to resell thancomparable U.S. securities because the markets forforeign securities are often less liquid. Even when aforeign security increases in price in its local currency,the appreciation may be diluted by adverse changes in

TSF-9

Page 54: Single Premium Immediate Variable Annuity · PDF fileSingle Premium Immediate Variable Annuity Issued between 7/26/1999 and 4/29/2016. Prospectuses April 30, 2017 Thrivent Variable

exchange rates when the security’s value is converted toU.S. dollars. Foreign withholding taxes also may applyand errors and delays may occur in the settlementprocess for foreign securities. All of these risks may beheightened for securities of issuers located in, or withsignificant operations in, emerging market countries.

High Yield Risk. High yield securities – commonlyknown as “junk bonds” – to which the Portfolio isexposed are considered predominantly speculative withrespect to the issuer’s continuing ability to makeprincipal and interest payments. If the issuer of thesecurity is in default with respect to interest or principalpayments, the value of the Portfolio may be negativelyaffected.

Interest Rate Risk. Interest rate risk is the risk thatprices of debt securities decline in value when interestrates rise for debt securities that pay a fixed rate ofinterest. Debt securities with longer durations (ameasure of price sensitivity of a bond or bond fund tochanges in interest rates) or maturities (i.e., the amountof time until a bond’s issuer must pay its principal orface value) tend to be more sensitive to changes ininterest rates than debt securities with shorter durationsor maturities. In addition, both mortgage-backed andasset-backed securities are sensitive to changes in therepayment patterns of the underlying security. If theprincipal payment on the underlying asset is repaidfaster or slower than the holder of the asset-backed ormortgage-backed security anticipates, the price of thesecurity may fall, particularly if the holder must reinvestthe repaid principal at lower rates or must continue tohold the security when interest rates rise. This effectmay cause the value of the Portfolio to decline andreduce the overall return of the Portfolio. Changes bythe Federal Reserve to monetary policies could affectinterest rates and the value of some securities.

Investment Adviser Risk. The Portfolio is activelymanaged and the success of its investment strategydepends significantly on the skills of the Adviser inassessing the potential of the investments in which thePortfolio invests. This assessment of investments mayprove incorrect, resulting in losses or poor performance,even in rising markets.

Issuer Risk. Issuer risk is the possibility that factorsspecific to a company to which the Portfolio is exposedwill affect the market prices of the company’s securitiesand therefore the value of the Portfolio. Common stockof a company is subordinate to other securities issued bythe company. If a company becomes insolvent, interestsof investors owning common stock will be subordinatedto the interests of other investors in, and generalcreditors of, the company.

Leveraged Loan Risk. Leveraged loans (also known asbank loans) are subject to the risks typically associatedwith debt securities. In addition, leveraged loans, which

typically hold a senior position in the capital structureof a borrower, are subject to the risk that a court couldsubordinate such loans to presently existing or futureindebtedness or take other action detrimental to theholders of leveraged loans. Leveraged loans are alsosubject to the risk that the value of the collateral, if any,securing a loan may decline, be insufficient to meet theobligations of the borrower, or be difficult to liquidate.Some leveraged loans are not as easily purchased or soldas publicly-traded securities and others are illiquid,which may make it more difficult for the Portfolio tovalue them or dispose of them at an acceptable price.Below investment-grade leveraged loans are typicallymore credit sensitive. In the event of fraud ormisrepresentation, the Portfolio may not be protectedunder federal securities laws with respect to leveragedloans that may not be in the form of “securities.” Thesettlement period for some leveraged loans may be morethan seven days.

Liquidity Risk. Liquidity is the ability to sell a securityrelatively quickly for a price that most closely reflectsthe actual value of the security. High-yield bonds andleveraged loans have a less liquid resale market. Inaddition, dealer inventories of bonds are at or nearhistoric lows in relation to market size, which has thepotential to decrease liquidity and increase pricevolatility in the fixed income markets, particularlyduring periods of economic or market stress. As a result,the Adviser may have difficulty selling or disposing ofsecurities quickly in certain markets or may only be ableto sell the holdings at prices substantially less than whatthe Adviser believes they are worth.

Market Risk. Over time, securities markets generallytend to move in cycles with periods when securityprices rise and periods when security prices decline. Thevalue of the Portfolio’s investments may move withthese cycles and, in some instances, increase or decreasemore than the applicable market(s) as measured by thePortfolio’s benchmark index(es). The securities marketsmay also decline because of factors that affect aparticular industry.

Mortgage-Related and Other Asset-BackedSecurities Risk. The value of mortgage-related andasset-backed securities will be influenced by the factorsaffecting the housing market and the assets underlyingsuch securities. As a result, during periods of decliningasset value, difficult or frozen credit markets, swings ininterest rates, or deteriorating economic conditions,mortgage-related and asset-backed securities maydecline in value, face valuation difficulties, becomemore volatile and/or become illiquid.

Other Funds Risk. The performance of the Portfolio isdependent, in part, upon the performance of otherfunds manged by the Adviser or an affiliate (“OtherFunds”) in which the Portfolio may invest. As a result,

TSF-10

Page 55: Single Premium Immediate Variable Annuity · PDF fileSingle Premium Immediate Variable Annuity Issued between 7/26/1999 and 4/29/2016. Prospectuses April 30, 2017 Thrivent Variable

the Portfolio is subject to the same risks as those facedby the Other Funds.

Portfolio Turnover Rate Risk. The Portfolio mayengage in active and frequent trading of portfoliosecurities in implementing its principal investmentstrategies. A high rate of portfolio turnover (100% ormore) involves correspondingly greater expenses whichare borne by the Portfolio and its shareholders and mayalso result in short-term capital gains taxable toshareholders.

Preferred Securities Risk. There are certainadditional risks associated with investing in preferredsecurities, including, but not limited to, preferredsecurities may include provisions that permit the issuer,at its discretion, to defer or omit distributions for astated period without any adverse consequences to theissuer; preferred securities are generally subordinated tobonds and other debt instruments in a company’scapital structure in terms of having priority to corporateincome and liquidation payments, and therefore will besubject to greater credit risk than more senior debtinstruments; preferred securities may be substantiallyless liquid than many other securities, such as commonstocks or U.S. Government securities; generally,traditional preferred securities offer no voting rightswith respect to the issuing company unless preferreddividends have been in arrears for a specified number ofperiods, at which time the preferred security holdersmay elect a number of directors to the issuer’s board;and in certain varying circumstances, an issuer ofpreferred securities may redeem the securities prior to aspecified date.

Real Estate Investment Trust (“REIT”) Risk. REITsgenerally can be divided into three types: equity REITs,mortgage REITs, and hybrid REITs (which combine thecharacteristics of equity REITs and mortgage REITs).Equity REITs will be affected by changes in the values of,and income from, the properties they own, whilemortgage REITs may be affected by the credit quality ofthe mortgage loans they hold. All REIT types may beaffected by changes in interest rates. REITs are subject toadditional risks, including the fact that they aredependent on specialized management skills that mayaffect the REITs’ abilities to generate cash flows foroperating purposes and for making investordistributions. REITs may have limited diversificationand are subject to the risks associated with obtainingfinancing for real property. As with any investment,there is a risk that REIT securities and other real estateindustry investments may be overvalued at the time ofpurchase. In addition, a REIT can pass its incomethrough to its investors without any tax at the entitylevel if it complies with various requirements under theInternal Revenue Code. There is the risk, however, thata REIT held by the Portfolio will fail to qualify for thistax-free pass-through treatment of its income. In

addition, due to recent changes in the tax laws, certaintax benefits of REITs may not be passed through tomutual fund shareholders. By investing in REITsindirectly through the Portfolio, in addition to bearing aproportionate share of the expenses of the Portfolio, youwill also indirectly bear similar expenses of the REITs inwhich the Portfolio invests.

Sovereign Debt Risk. Sovereign debt securities areissued or guaranteed by foreign governmental entities.These investments are subject to the risk that agovernmental entity may delay or refuse to pay interestor repay principal on its sovereign debt, due, forexample, to cash flow problems, insufficient foreigncurrency reserves, political considerations, the relativesize of the governmental entity’s debt position inrelation to the economy or the failure to put in placeeconomic reforms required by the InternationalMonetary Fund or other multilateral agencies.

Volatility Risk. Volatility risk is the risk that certaintypes of securities shift in and out of favor dependingon market and economic conditions as well as investorsentiment. The value of the Portfolio’s shares may beaffected by weak equity markets or changes in interestrate or bond yield levels. As a result, the value of thePortfolio’s shares may fluctuate significantly in the shortterm.

PerformanceThe following bar chart and table provide an indicationof the risks of investing in the Portfolio by showingchanges in the Portfolio’s performance from year to yearand by showing how the Portfolio’s average annualreturns for one-, five- and ten-year periods compared tobroad-based securities market indices. These indices arethe MSCI World Index—USD Net Returns, whichmeasures the performance of stock markets indeveloped countries throughout the world, theBloomberg Barclays U.S. Mortgage-Backed SecuritiesIndex, which covers the mortgage-backed securitiescomponent of the Bloomberg Barclays U.S. AggregateBond Index, the Bloomberg Barclays U.S. High YieldBa/B 2% Issuer Capped Index, which represents theperformance of high yield corporate bonds rated Ba orB, with a maximum allocation of 2% to any one issuer,and the S&P/LSTA Leveraged Loan Index, which reflectsthe performance of the largest facilities in the leveragedloan market.

on applicable charges and expenses. If the charges anddeductions against your variable contract were included,returns would be lower than those shown.

Effective August 16, 2013, based on approval of thePortfolio’s Board of Directors and notice to Portfolioshareholders, the Portfolio’s principal strategies werechanged, which had the effect of converting thePortfolio from one which incorporated the strategies ofThrivent Large Cap Index Portfolio and Thrivent BondIndex Portfolio (now known as Thrivent GovernmentBond Portfolio) to one which invests in a combinationequity securities and debt securities. At the same time,the Portfolio’s name changed from Thrivent BalancedPortfolio to Thrivent Balanced Income Plus Portfolio.

Portfolio TurnoverThe Portfolio pays transaction costs, such ascommissions, when it buys and sells securities (or “turnsover” its portfolio). A higher portfolio turnover rate mayindicate higher transaction costs and may result inhigher taxes when Portfolio shares are held in a taxableaccount. These costs, which are not reflected in annualfund operating expenses or in the example, affect thePortfolio’s performance. During the most recent fiscalyear, the Portfolio’s portfolio turnover rate was 146% ofthe average value of its portfolio.

Principal StrategiesUnder normal circumstances, the Portfolio invests in acombination of equity securities and debt securitieswithin the ranges shown in the following table:

The equity securities in which the Portfolio invests areprimarily income-producing and may include commonstock, preferred stock, securities convertible intocommon stock, or securities or other instruments theprice of which is linked to the value of common stock.Under normal circumstances, the Portfolio intends toinvest in real estate investment trusts (“REITs”).

The debt securities in which the Portfolio invests maybe of any maturity or credit quality, including highyield, high risk bonds, notes, debentures and other debtobligations commonly known as “junk bonds.” At thetime of purchase, these high-yield securities are ratedwithin or below the “BB” major rating category by S&Por the “Ba” major rating category by Moody’s or areunrated but considered to be of comparable quality bythe Adviser. The Portfolio may also invest in leveragedloans, which are senior secured loans that are made bybanks or other lending institutions to companies thatare rated below investment grade. In addition, thePortfolio may invest in investment-grade corporatebonds, asset-backed securities, mortgage-backedsecurities (including commercially backed ones),convertible bonds, and sovereign and emerging marketdebt (both U.S. dollar and non-U.S. dollardenominated).

The Portfolio may utilize derivatives (such as futuresand swaps) for investment exposure or hedgingpurposes, including credit default swap agreements onsecurity indexes. The Portfolio may enter intostandardized derivatives contracts traded on domestic orforeign securities exchanges, boards of trade, or similar

entities, and non-standardized derivatives contractstraded in the over-the-counter market.

The Portfolio may invest in foreign securities, includingthose of issuers in emerging markets. An “emergingmarket” country is any country determined by theAdviser to have an emerging market economy,considering factors such as the country’s credit rating,its political and economic stability and the developmentof its financial and capital markets.

The Portfolio may invest in exchange-traded funds(“ETFs”), which are investment companies generallydesigned to track the performance of a securities orother index or benchmark.

The Portfolio may also pursue its investment strategy byinvesting in other mutual funds, including fundsmanaged by the Adviser or an affiliate.

The Adviser uses fundamental, quantitative andtechnical investment research techniques to determinewhat to buy and sell. Fundamental techniques assess asecurity’s value based on an issuer’s financial profile,management, and business prospects while quantitativeand technical techniques involve a more data-orientedanalysis of financial information, market trends andprice movements.

Principal RisksThe Portfolio is subject to the following principalinvestment risks. Shares of the Portfolio will rise and fallin value and there is a risk that you could lose moneyby investing in the Portfolio. The Portfolio cannot becertain that it will achieve its investment objective.

Allocation Risk. The Portfolio’s investmentperformance depends upon how its assets are allocatedacross broad asset categories and applicable sub-classeswithin such categories. Some broad asset categories andsub-classes may perform below expectations or thesecurities markets generally over short and extendedperiods. In particular, underperformance in the fixedincome markets would have a material adverse effect onthe Portfolio’s total return given its significantallocation to fixed income securities. Therefore, aprincipal risk of investing in the Portfolio is that theallocation strategies used and the allocation decisionsmade will not produce the desired results.

Convertible Securities Risk. Convertible securities aresubject to the usual risks associated with debt securities,such as interest rate risk and credit risk. Convertiblesecurities also react to changes in the value of thecommon stock into which they convert, and are thussubject to market risk. The Portfolio may also be forcedto convert a convertible security at an inopportunetime, which may decrease the Portfolio’s return.

Credit Risk. Credit risk is the risk that an issuer of adebt security to which the Portfolio is exposed may no

longer be able or willing to pay its debt. As a result ofsuch an event, the debt security may decline in priceand affect the value of the Portfolio.

Derivatives Risk. The use of derivatives (such asfutures and credit default swaps) involves additionalrisks and transaction costs which could leave thePortfolio in a worse position than if it had not usedthese instruments. The use of derivatives can lead tolosses because of adverse movements in the price orvalue of the underlying asset, index or rate, which maybe magnified by certain features of the contract.Changes in the value of the derivative may not correlateas intended with the underlying asset, rate or index, andthe Portfolio could lose much more than the originalamount invested. Derivatives can be highly volatile,illiquid and difficult to value. Certain derivatives mayalso be subject to counterparty risk, which is that theother party in the transaction will not fulfill itscontractual obligations due to its financial condition,market events, or other reasons.

Emerging Markets Risk. The economic and politicalstructures of developing countries, in most cases, do notcompare favorably with the U.S. or other developedcountries in terms of wealth and stability, and theirfinancial markets often lack liquidity. Portfolioperformance will likely be negatively affected byportfolio exposure to countries in the midst of, amongother things, hyperinflation, currency devaluation,trade disagreements, sudden political upheaval, orinterventionist government policies. Significant buyingor selling actions by a few major investors may alsoheighten the volatility of emerging markets. Thesefactors make investing in emerging market countriessignificantly riskier than in other countries, and eventsin any one country could cause the Portfolio’s shareprice to decline.

ETF Risk. An ETF is subject to the risks of theunderlying investments that it holds. In addition, forindex-based ETFs, the performance of an ETF maydiverge from the performance of such index (commonlyknown as tracking error). ETFs are subject to fees andexpenses (like management fees and operatingexpenses) that do not apply to an index, and thePortfolio will indirectly bear its proportionate share ofany such fees and expenses paid by the ETFs in which itinvests.

Foreign Securities Risk. Foreign securities aregenerally more volatile than their domesticcounterparts, in part because of higher political andeconomic risks, lack of reliable information andfluctuations in currency exchange rates. Foreignsecurities may also be more difficult to resell thancomparable U.S. securities because the markets forforeign securities are often less liquid. Even when aforeign security increases in price in its local currency,the appreciation may be diluted by adverse changes in

Page 61: Single Premium Immediate Variable Annuity · PDF fileSingle Premium Immediate Variable Annuity Issued between 7/26/1999 and 4/29/2016. Prospectuses April 30, 2017 Thrivent Variable

exchange rates when the security’s value is converted toU.S. dollars. Foreign withholding taxes also may applyand errors and delays may occur in the settlementprocess for foreign securities. All of these risks may beheightened for securities of issuers located in, or withsignificant operations in, emerging market countries.

High Yield Risk. High yield securities – commonlyknown as “junk bonds” – to which the Portfolio isexposed are considered predominantly speculative withrespect to the issuer’s continuing ability to makeprincipal and interest payments. If the issuer of thesecurity is in default with respect to interest or principalpayments, the value of the Portfolio may be negativelyaffected.

Interest Rate Risk. Interest rate risk is the risk thatprices of debt securities decline in value when interestrates rise for debt securities that pay a fixed rate ofinterest. Debt securities with longer durations (ameasure of price sensitivity of a bond or bond fund tochanges in interest rates) or maturities (i.e., the amountof time until a bond’s issuer must pay its principal orface value) tend to be more sensitive to changes ininterest rates than debt securities with shorter durationsor maturities. In addition, both mortgage-backed andasset-backed securities are sensitive to changes in therepayment patterns of the underlying security. If theprincipal payment on the underlying asset is repaidfaster or slower than the holder of the asset-backed ormortgage-backed security anticipates, the price of thesecurity may fall, particularly if the holder must reinvestthe repaid principal at lower rates or must continue tohold the security when interest rates rise. This effectmay cause the value of the Portfolio to decline andreduce the overall return of the Portfolio. Changes bythe Federal Reserve to monetary policies could affectinterest rates and the value of some securities.

Investment Adviser Risk. The Portfolio is activelymanaged and the success of its investment strategydepends significantly on the skills of the Adviser inassessing the potential of the investments in which thePortfolio invests. This assessment of investments mayprove incorrect, resulting in losses or poor performance,even in rising markets.

Issuer Risk. Issuer risk is the possibility that factorsspecific to a company to which the Portfolio is exposedwill affect the market prices of the company’s securitiesand therefore the value of the Portfolio. Common stockof a company is subordinate to other securities issued bythe company. If a company becomes insolvent, interestsof investors owning common stock will be subordinatedto the interests of other investors in, and generalcreditors of, the company.

Leveraged Loan Risk. Leveraged loans (also known asbank loans) are subject to the risks typically associatedwith debt securities. In addition, leveraged loans, which

typically hold a senior position in the capital structureof a borrower, are subject to the risk that a court couldsubordinate such loans to presently existing or futureindebtedness or take other action detrimental to theholders of leveraged loans. Leveraged loans are alsosubject to the risk that the value of the collateral, if any,securing a loan may decline, be insufficient to meet theobligations of the borrower, or be difficult to liquidate.Some leveraged loans are not as easily purchased or soldas publicly-traded securities and others are illiquid,which may make it more difficult for the Portfolio tovalue them or dispose of them at an acceptable price.Below investment-grade leveraged loans are typicallymore credit sensitive. In the event of fraud ormisrepresentation, the Portfolio may not be protectedunder federal securities laws with respect to leveragedloans that may not be in the form of “securities.” Thesettlement period for some leveraged loans may be morethan seven days.

Liquidity Risk. Liquidity is the ability to sell a securityrelatively quickly for a price that most closely reflectsthe actual value of the security. High-yield bonds andleveraged loans have a less liquid resale market. Inaddition, dealer inventories of bonds are at or nearhistoric lows in relation to market size, which has thepotential to decrease liquidity and increase pricevolatility in the fixed income markets, particularlyduring periods of economic or market stress. As a result,the Adviser may have difficulty selling or disposing ofsecurities quickly in certain markets or may only be ableto sell the holdings at prices substantially less than whatthe Adviser believes they are worth.

Market Risk. Over time, securities markets generallytend to move in cycles with periods when securityprices rise and periods when security prices decline. Thevalue of the Portfolio’s investments may move withthese cycles and, in some instances, increase or decreasemore than the applicable market(s) as measured by thePortfolio’s benchmark index(es). The securities marketsmay also decline because of factors that affect aparticular industry.

Mortgage-Related and Other Asset-BackedSecurities Risk. The value of mortgage-related andasset-backed securities will be influenced by the factorsaffecting the housing market and the assets underlyingsuch securities. As a result, during periods of decliningasset value, difficult or frozen credit markets, swings ininterest rates, or deteriorating economic conditions,mortgage-related and asset-backed securities maydecline in value, face valuation difficulties, becomemore volatile and/or become illiquid.

Other Funds Risk. The performance of the Portfolio isdependent, in part, upon the performance of otherfunds manged by the Adviser or an affiliate (“OtherFunds”) in which the Portfolio may invest. As a result,

TSF-17

Page 62: Single Premium Immediate Variable Annuity · PDF fileSingle Premium Immediate Variable Annuity Issued between 7/26/1999 and 4/29/2016. Prospectuses April 30, 2017 Thrivent Variable

the Portfolio is subject to the same risks as those facedby the Other Funds.

Portfolio Turnover Rate Risk. The Portfolio mayengage in active and frequent trading of portfoliosecurities in implementing its principal investmentstrategies. A high rate of portfolio turnover (100% ormore) involves correspondingly greater expenses whichare borne by the Portfolio and its shareholders and mayalso result in short-term capital gains taxable toshareholders.

Preferred Securities Risk. There are certainadditional risks associated with investing in preferredsecurities, including, but not limited to, preferredsecurities may include provisions that permit the issuer,at its discretion, to defer or omit distributions for astated period without any adverse consequences to theissuer; preferred securities are generally subordinated tobonds and other debt instruments in a company’scapital structure in terms of having priority to corporateincome and liquidation payments, and therefore will besubject to greater credit risk than more senior debtinstruments; preferred securities may be substantiallyless liquid than many other securities, such as commonstocks or U.S. Government securities; generally,traditional preferred securities offer no voting rightswith respect to the issuing company unless preferreddividends have been in arrears for a specified number ofperiods, at which time the preferred security holdersmay elect a number of directors to the issuer’s board;and in certain varying circumstances, an issuer ofpreferred securities may redeem the securities prior to aspecified date.

Real Estate Investment Trust (“REIT”) Risk. REITsgenerally can be divided into three types: equity REITs,mortgage REITs, and hybrid REITs (which combine thecharacteristics of equity REITs and mortgage REITs).Equity REITs will be affected by changes in the values of,and income from, the properties they own, whilemortgage REITs may be affected by the credit quality ofthe mortgage loans they hold. All REIT types may beaffected by changes in interest rates. REITs are subject toadditional risks, including the fact that they aredependent on specialized management skills that mayaffect the REITs’ abilities to generate cash flows foroperating purposes and for making investordistributions. REITs may have limited diversificationand are subject to the risks associated with obtainingfinancing for real property. As with any investment,there is a risk that REIT securities and other real estateindustry investments may be overvalued at the time ofpurchase. In addition, a REIT can pass its incomethrough to its investors without any tax at the entitylevel if it complies with various requirements under theInternal Revenue Code. There is the risk, however, thata REIT held by the Portfolio will fail to qualify for thistax-free pass-through treatment of its income. In

addition, due to recent changes in the tax laws, certaintax benefits of REITs may not be passed through tomutual fund shareholders. By investing in REITsindirectly through the Portfolio, in addition to bearing aproportionate share of the expenses of the Portfolio, youwill also indirectly bear similar expenses of the REITs inwhich the Portfolio invests.

Volatility Risk. Volatility risk is the risk that certaintypes of securities shift in and out of favor dependingon market and economic conditions as well as investorsentiment. The value of the Portfolio’s shares may beaffected by weak equity markets or changes in interestrate or bond yield levels. As a result, the value of thePortfolio’s shares may fluctuate significantly in the shortterm.

PerformanceThe following bar chart and table provide an indicationof the risks of investing in the Portfolio by showingchanges in the Portfolio’s performance from year to yearand by showing how the Portfolio’s average annualreturns for one-, five- and ten-year periods compared tobroad-based securities market indices. These indices arethe MSCI World Index—USD Net Returns, whichmeasures the performance of stock markets indeveloped countries throughout the world, theBloomberg Barclays U.S. Mortgage-Backed SecuritiesIndex, which covers the mortgage-backed securitiescomponent of the Bloomberg Barclays U.S. AggregateBond Index, the Bloomberg Barclays U.S. High YieldBa/B 2% Issuer Capped Index, which represents theperformance of high yield corporate bonds rated Ba orB, with a maximum allocation of 2% to any one issuer,and the S&P/LSTA Leveraged loan Index, which reflectsthe performance of the largest facilities in the leveragedloan market.

Call 800-847-4836 or visit Thrivent.com forperformance results current to the most recentmonth-end.

The bar chart and table include the effects of Portfolioexpenses, but not charges or deductions against yourvariable contract, and assume that you sold yourinvestment at the end of the period. Because shares ofthe Portfolio are offered through variable life insuranceand variable annuity contracts, you should carefullyreview the variable contract prospectus for informationon applicable charges and expenses. If the charges anddeductions against your variable contract were included,returns would be lower than those shown.

How a Portfolio has performed in the past is notnecessarily an indication of how it will perform in thefuture. Performance information provides someindication of the risks of investing in the Portfolio byshowing changes in the Portfolio’s performance overtime.

Portfolio TurnoverThe Portfolio pays transaction costs, such ascommissions, when it buys and sells securities (or “turnsover” its portfolio). A higher portfolio turnover rate mayindicate higher transaction costs and may result inhigher taxes when Portfolio shares are held in a taxableaccount. These costs, which are not reflected in annualfund operating expenses or in the example, affect thePortfolio’s performance. During the most recent fiscalyear, the Portfolio’s portfolio turnover rate was 422% ofthe average value of its portfolio.

Principal StrategiesUnder normal circumstances, the Portfolio invests atleast 80% of its net assets (plus the amount ofborrowings for investment purposes) in U.S.government bonds. For purposes of this disclosure, “U.S.government bonds” are debt instruments issued orguaranteed by the U.S. government or its agencies andinstrumentalities, including U.S. Treasuries, TreasuryInflation Protected Securities (TIPS), U.S. GovernmentAgency debt, and mortgage-backed securities issued orguaranteed by the Government National MortgageAssociation (GNMA or Ginnie Mae), the FederalNational Mortgage Association (FNMA or Fannie Mae)or the Federal Home Loan Mortgage Corporation(FHLMC or Freddie Mac). Should the Adviser determinethat the Portfolio would benefit from reducing thepercentage of its net assets invested in U.S. governmentbonds from 80% to a lesser amount, it will notify you atleast 60 days prior to the change.

The Portfolio’s portfolio securities may be of anymaturity. The Adviser uses fundamental, quantitativeand technical investment research techniques todetermine what debt obligations to buy and sell.Fundamental techniques assess a security’s value basedon an issuer’s financial profile, management, andbusiness prospects while quantitative and technicaltechniques involve a more data-oriented analysis offinancial information, market trends and pricemovements. The “total return” sought by the Portfolioconsists of income earned on the Portfolio’s investmentsplus, if any, capital appreciation. The Portfolio mayinvest in U.S. dollar denominated sovereign debt offoreign governments. The Portfolio may also pursue itsinvestment strategy by investing in other mutual funds,including funds managed by the Adviser or an affiliate.

entities, and non-standardized derivatives contractstraded in the over-the-counter market.

Principal RisksThe Portfolio is subject to the following principalinvestment risks. Shares of the Portfolio will rise and fallin value and there is a risk that you could lose moneyby investing in the Portfolio. The Portfolio cannot becertain that it will achieve its investment objective.

Derivatives Risk. The use of derivatives (such asfutures and credit default swaps) involves additionalrisks and transaction costs which could leave thePortfolio in a worse position than if it had not usedthese instruments. The use of derivatives can lead tolosses because of adverse movements in the price orvalue of the underlying asset, index or rate, which maybe magnified by certain features of the contract.Changes in the value of the derivative may not correlateas intended with the underlying asset, rate or index, andthe Portfolio could lose much more than the originalamount invested. Derivatives can be highly volatile,illiquid and difficult to value. Certain derivatives mayalso be subject to counterparty risk, which is that theother party in the transaction will not fulfill itscontractual obligations due to its financial condition,market events, or other reasons.

Government Securities Risk. The Portfolio invests insecurities issued or guaranteed by the U.S. governmentor its agencies and instrumentalities (such as GinnieMae, Fannie Mae or Freddie Mac securities). Securitiesissued or guaranteed by Ginnie Mae, Fannie Mae orFreddie Mac are not issued directly by the U.S.government. Ginnie Mae is a wholly owned U.S.corporation that is authorized to guarantee, with thefull faith and credit of the U.S. government, the timelypayment of principal and interest of its securities. Bycontrast, securities issued or guaranteed by U.S.government-related organizations such as Fannie Maeand Freddie Mac are not backed by the full faith andcredit of the U.S. government. No assurance can begiven that the U.S. government would provide financialsupport to its agencies and instrumentalities if notrequired to do so by law. In addition, the value of U.S.government securities may be affected by changes in thecredit rating of the U.S. government.

Inflation-Linked Security Risk. Inflation-linked debtsecurities, such as TIPS, are subject to the effects ofchanges in market interest rates caused by factors otherthan inflation (real interest rates). In general, the priceof an inflation-linked security tends to decrease whenreal interest rates increase and can increase when realinterest rates decrease. Interest payments oninflation-linked securities are unpredictable and willfluctuate as the principal and interest are adjusted forinflation. Any increase in the principal amount of aninflation-linked debt security will be considered taxable

ordinary income, even though the Portfolio will notreceive the principal until maturity.

There can also be no assurance that the inflation indexused will accurately measure the real rate of inflation inthe prices of goods and services. The Portfolio’sinvestments in inflation-linked securities may lose valuein the event that the actual rate of inflation is differentthan the rate of the inflation index. In addition,inflation-linked securities are subject to the risk that theConsumer Price Index for All Urban Consumers (CPI-U)or other relevant pricing index may be discontinued,fundamentally altered in a manner materially adverse tothe interests of an investor in the securities, altered bylegislation or Executive Order in a materially adversemanner to the interests of an investor in the securitiesor substituted with an alternative index.

Interest Rate Risk. Interest rate risk is the risk thatprices of debt securities decline in value when interestrates rise for debt securities that pay a fixed rate ofinterest. Debt securities with longer durations (ameasure of price sensitivity of a bond or bond fund tochanges in interest rates) or maturities (i.e., the amountof time until a bond’s issuer must pay its principal orface value) tend to be more sensitive to changes ininterest rates than debt securities with shorter durationsor maturities. Some municipal bonds may be repaidprior to maturity if interest rates decrease. Changes bythe Federal Reserve to monetary policies could affectinterest rates and the value of some securities.

Investment Adviser Risk. The Portfolio is activelymanaged and the success of its investment strategydepends significantly on the skills of the Adviser inassessing the potential of the investments in which thePortfolio invests. This assessment of investments mayprove incorrect, resulting in losses or poor performance,even in rising markets.

Issuer Risk. Issuer risk is the possibility that factorsspecific to a company to which the Portfolio is exposedwill affect the market prices of the company’s securitiesand therefore the value of the Portfolio. Some factorsaffecting the performance of a company includedemand for the company’s products or services, thequality of management of the company and brandrecognition and loyalty.

Liquidity Risk. Liquidity is the ability to sell a securityrelatively quickly for a price that most closely reflectsthe actual value of the security. Inventories of bonds areat or near historic lows in relation to market size, whichhas the potential to decrease liquidity and increase pricevolatility in the fixed income markets, particularlyduring periods of economic or market stress. As a resultof this decreased liquidity, the Adviser may have toaccept a lower price to sell a security, sell other securitiesto raise cash, or give up an investment opportunity, anyof which could have a negative effect on performance.

Market Risk. Over time, securities markets generallytend to move in cycles with periods when securityprices rise and periods when security prices decline. Thevalue of the Portfolio’s investments may move withthese cycles and, in some instances, increase or decreasemore than the applicable market(s) as measured by thePortfolio’s benchmark index(es). The securities marketsmay also decline because of factors that affect aparticular industry.

Mortgage-Related and Other Asset-BackedSecurities Risk. The value of mortgage-related andasset-backed securities will be influenced by the factorsaffecting the housing market and the assets underlyingsuch securities. As a result, during periods of decliningasset value, difficult or frozen credit markets, swings ininterest rates, or deteriorating economic conditions,mortgage-related and asset-backed securities maydecline in value, face valuation difficulties, becomemore volatile and/or become illiquid.

Other Funds Risk. The performance of the Portfolio isdependent, in part, upon the performance of otherfunds manged by the Adviser or an affiliate (“OtherFunds”) in which the Portfolio may invest. As a result,the Portfolio is subject to the same risks as those facedby the Other Funds.

Portfolio Turnover Rate Risk. The Portfolio mayengage in active and frequent trading of portfoliosecurities in implementing its principal investmentstrategies. A high rate of portfolio turnover (100% ormore) involves correspondingly greater expenses whichare borne by the Portfolio and its shareholders and mayalso result in short-term capital gains taxable toshareholders.

Sovereign Debt Risk. The Portfolio may invest insovereign debt securities. These securities are issued orguaranteed by foreign governmental entities. Theseinvestments are subject to the risk that a governmentalentity may delay or refuse to pay interest or repayprincipal on its sovereign debt, due, for example, tocash flow problems, insufficient foreign currencyreserves, political considerations, the relative size of thegovernmental entity’s debt position in relation to theeconomy or the failure to put in place economicreforms required by the International Monetary Fund orother multilateral agencies. If a governmental entitydefaults, it may ask for more time in which to pay or forfurther loans. There is no legal process for collectingsovereign debts that a government does not pay nor arethere bankruptcy proceedings through which all or partof the sovereign debt that a governmental entity hasnot repaid may be collected.

PerformanceThe following bar chart and table provide an indicationof the risks of investing in the Portfolio by showingchanges in the Portfolio’s performance from year to year

and by showing how the Portfolio’s average annualreturns for one-, five- and ten-year periods compared tobroad-based securities market indices. The indices areBloomberg Barclays U.S. Agency Index and theBloomberg Barclays U.S. Treasury Index. The BloombergBarclays U.S. Agency Index measures the performance ofthe agency sector of the U.S. government bond market.The Bloomberg Barclays U.S. Treasury Index measuresthe performance of the U.S. Treasury bond market. Call800-847-4836 or visit Thrivent.com for performanceresults current to the most recent month-end.

The Portfolio no longer uses the Bloomberg BarclaysU.S. Aggregate Bond Index because, effective August 28,2017, based on approval of the Portfolio’s Board ofDirectors and shareholders, the portfolio’s investmentobjective and principal strategies were changed, whichhad the effect of converting the Portfolio from onewhose securities were selected based on which securitieswere in an index to one that is actively managed andinvests primarily in U.S. government securities. At thesame time, the Portfolio’s name changed from ThriventBond Index Portfolio to Thrivent Government BondPortfolio. As a result, performance informationpresented below with respect to periods prior toAugust 28, 2017, reflects the performance of aninvestment portfolio that was materially different fromthe investment portfolio of Thrivent Government BondPortfolio.

The bar chart and the table include the effects ofPortfolio expenses, but not charges or deductionsagainst your variable contract, and assume that you soldyour shares at the end of the period. Because shares ofthe Portfolio are offered through variable life insuranceand variable annuity contracts, you should carefullyreview the variable contract prospectus for informationon applicable charges and expenses. If the charges anddeductions against your variable contract were included,returns would be lower than those shown.

How the Portfolio has performed in the past (before andafter taxes) is not necessarily an indication of how it willperform in the future. Performance informationprovides some indication of the risks of investing in thePortfolio by showing changes in the Portfolio’sperformance over time.

The debt securities in which the Portfolio invests maybe of any maturity or credit quality, including highyield, high risk bonds, notes, debentures and other debtobligations commonly known as “junk bonds.” At thetime of purchase, these high-yield securities are ratedwithin or below the “BB” major rating category by S&Por the “Ba” major rating category by Moody’s or areunrated but considered to be of comparable quality bythe Adviser. The Portfolio may also invest in leveragedloans, which are senior secured loans that are made bybanks or other lending institutions to companies thatare rated below investment grade. In addition, thePortfolio may invest in investment-grade corporatebonds, asset-backed securities, mortgage-backedsecurities (including commercially backed ones),convertible bonds, and sovereign and emerging marketdebt (both U.S. dollar and non-U.S. dollardenominated).

The Portfolio may utilize derivatives (such as futuresand swaps) for investment exposure or hedgingpurposes, including credit default swap agreements onsecurity indexes. The Portfolio may enter intostandardized derivatives contracts traded on domestic orforeign securities exchanges, boards of trade, or similarentities, and non-standardized derivatives contractstraded in the over-the-counter market.

The Portfolio may invest in foreign securities, includingthose of issuers in emerging markets. An “emergingmarket” country is any country determined by theAdviser to have an emerging market economy,considering factors such as the country’s credit rating,its political and economic stability and the developmentof its financial and capital markets.

The Portfolio may invest in exchange-traded funds(“ETFs”), which are investment companies generallydesigned to track the performance of a securities orother index or benchmark.

The Portfolio may also pursue its investment strategy byinvesting in other mutual funds, including fundsmanaged by the Adviser or an affiliate.

The Adviser uses fundamental, quantitative andtechnical investment research techniques to determinewhat to buy and sell. Fundamental techniques assess asecurity’s value based on an issuer’s financial profile,management, and business prospects while quantitativeand technical techniques involve a more data-orientedanalysis of financial information, market trends andprice movements.

Principal RisksThe Portfolio is subject to the following principalinvestment risks. Shares of the Portfolio will rise and fallin value and there is a risk that you could lose moneyby investing in the Portfolio. The Portfolio cannot becertain that it will achieve its investment objective.

Allocation Risk. The Portfolio’s investmentperformance depends upon how its assets are allocatedacross broad asset categories and applicable sub-classeswithin such categories. Some broad asset categories andsub-classes may perform below expectations or thesecurities markets generally over short and extendedperiods. In particular, underperformance in the equitymarkets would have a material adverse effect on thePortfolios’ total return given their significant allocationto equity securities. Therefore, a principal risk ofinvesting in the Portfolio is that the allocation strategiesused and the allocation decisions made will not producethe desired results.

Convertible Securities Risk. Convertible securities aresubject to the usual risks associated with debt securities,such as interest rate risk and credit risk. Convertiblesecurities also react to changes in the value of thecommon stock into which they convert, and are thussubject to market risk. The Portfolio may also be forcedto convert a convertible security at an inopportunetime, which may decrease the Portfolio’s return.

Credit Risk. Credit risk is the risk that an issuer of adebt security to which the Portfolio is exposed may nolonger be able or willing to pay its debt. As a result ofsuch an event, the debt security may decline in priceand affect the value of the Portfolio.

Derivatives Risk. The use of derivatives (such asfutures and credit default swaps) involves additionalrisks and transaction costs which could leave thePortfolio in a worse position than if it had not usedthese instruments. The use of derivatives can lead tolosses because of adverse movements in the price orvalue of the underlying asset, index or rate, which maybe magnified by certain features of the contract.Changes in the value of the derivative may not correlateas intended with the underlying asset, rate or index, andthe Portfolio could lose much more than the originalamount invested. Derivatives can be highly volatile,illiquid and difficult to value. Certain derivatives mayalso be subject to counterparty risk, which is that theother party in the transaction will not fulfill itscontractual obligations due to its financial condition,market events, or other reasons.

Emerging Markets Risk. The economic and politicalstructures of developing countries, in most cases, do notcompare favorably with the U.S. or other developedcountries in terms of wealth and stability, and theirfinancial markets often lack liquidity. Portfolioperformance will likely be negatively affected byportfolio exposure to countries in the midst of, amongother things, hyperinflation, currency devaluation,trade disagreements, sudden political upheaval, orinterventionist government policies. Significant buyingor selling actions by a few major investors may alsoheighten the volatility of emerging markets. Thesefactors make investing in emerging market countries

significantly riskier than in other countries, and eventsin any one country could cause the Portfolio’s shareprice to decline.

ETF Risk. An ETF is subject to the risks of theunderlying investments that it holds. In addition, forindex-based ETFs, the performance of an ETF maydiverge from the performance of such index (commonlyknown as tracking error). ETFs are subject to fees andexpenses (like management fees and operatingexpenses) that do not apply to an index, and thePortfolio will indirectly bear its proportionate share ofany such fees and expenses paid by the ETFs in which itinvests.

Foreign Securities Risk. Foreign securities aregenerally more volatile than their domesticcounterparts, in part because of higher political andeconomic risks, lack of reliable information andfluctuations in currency exchange rates. Foreignsecurities may also be more difficult to resell thancomparable U.S. securities because the markets forforeign securities are often less liquid. Even when aforeign security increases in price in its local currency,the appreciation may be diluted by adverse changes inexchange rates when the security’s value is converted toU.S. dollars. Foreign withholding taxes also may applyand errors and delays may occur in the settlementprocess for foreign securities. All of these risks may beheightened for securities of issuers located in, or withsignificant operations in, emerging market countries.

Growth Investing Risk. Growth style investingincludes the risk of investing in securities whose priceshistorically have been more volatile than othersecurities, especially over the short term. Growth stockprices reflect projections of future earnings or revenuesand, if a company’s earnings or revenues fall short ofexpectations, its stock price may fall dramatically.

High Yield Risk. High yield securities – commonlyknown as “junk bonds” – to which the Portfolio isexposed are considered predominantly speculative withrespect to the issuer’s continuing ability to makeprincipal and interest payments. If the issuer of thesecurity is in default with respect to interest or principalpayments, the value of the Portfolio may be negativelyaffected.

Interest Rate Risk. Interest rate risk is the risk thatprices of debt securities decline in value when interestrates rise for debt securities that pay a fixed rate ofinterest. Debt securities with longer durations (ameasure of price sensitivity of a bond or bond fund tochanges in interest rates) or maturities (i.e., the amountof time until a bond’s issuer must pay its principal orface value) tend to be more sensitive to changes ininterest rates than debt securities with shorter durationsor maturities. In addition, both mortgage-backed andasset-backed securities are sensitive to changes in the

repayment patterns of the underlying security. If theprincipal payment on the underlying asset is repaidfaster or slower than the holder of the asset-backed ormortgage-backed security anticipates, the price of thesecurity may fall, particularly if the holder must reinvestthe repaid principal at lower rates or must continue tohold the security when interest rates rise. This effectmay cause the value of the Portfolio to decline andreduce the overall return of the Portfolio. Changes bythe Federal Reserve to monetary policies could affectinterest rates and the value of some securities.

Investment Adviser Risk. The Portfolio is activelymanaged and the success of its investment strategydepends significantly on the skills of the Adviser inassessing the potential of the investments in which thePortfolio invests. This assessment of investments mayprove incorrect, resulting in losses or poor performance,even in rising markets.

Issuer Risk. Issuer risk is the possibility that factorsspecific to a company to which the Portfolio is exposedwill affect the market prices of the company’s securitiesand therefore the value of the Portfolio. Common stockof a company is subordinate to other securities issued bythe company. If a company becomes insolvent, interestsof investors owning common stock will be subordinatedto the interests of other investors in, and generalcreditors of, the company.

Leveraged Loan Risk. Leveraged loans (also known asbank loans) are subject to the risks typically associatedwith debt securities. In addition, leveraged loans, whichtypically hold a senior position in the capital structureof a borrower, are subject to the risk that a court couldsubordinate such loans to presently existing or futureindebtedness or take other action detrimental to theholders of leveraged loans. Leveraged loans are alsosubject to the risk that the value of the collateral, if any,securing a loan may decline, be insufficient to meet theobligations of the borrower, or be difficult to liquidate.Some leveraged loans are not as easily purchased or soldas publicly-traded securities and others are illiquid,which may make it more difficult for the Portfolio tovalue them or dispose of them at an acceptable price.Below investment-grade leveraged loans are typicallymore credit sensitive. In the event of fraud ormisrepresentation, the Portfolio may not be protectedunder federal securities laws with respect to leveragedloans that may not be in the form of “securities.” Thesettlement period for some leveraged loans may be morethan seven days.

Liquidity Risk. Liquidity is the ability to sell a securityrelatively quickly for a price that most closely reflectsthe actual value of the security. High-yield bonds andleveraged loans have a less liquid resale market. Inaddition, dealer inventories of bonds are at or nearhistoric lows in relation to market size, which has thepotential to decrease liquidity and increase price

volatility in the fixed income markets, particularlyduring periods of economic or market stress. As a result,the Adviser may have difficulty selling or disposing ofsecurities quickly in certain markets or may only be ableto sell the holdings at prices substantially less than whatthe Adviser believes they are worth.

Market Risk. Over time, securities markets generallytend to move in cycles with periods when securityprices rise and periods when security prices decline. Thevalue of the Portfolio’s investments may move withthese cycles and, in some instances, increase or decreasemore than the applicable market(s) as measured by thePortfolio’s benchmark index(es). The securities marketsmay also decline because of factors that affect aparticular industry.

Mortgage-Related and Other Asset-BackedSecurities Risk. The value of mortgage-related andasset-backed securities will be influenced by the factorsaffecting the housing market and the assets underlyingsuch securities. As a result, during periods of decliningasset value, difficult or frozen credit markets, swings ininterest rates, or deteriorating economic conditions,mortgage-related and asset-backed securities maydecline in value, face valuation difficulties, becomemore volatile and/or become illiquid.

Other Funds Risk. The performance of the Portfolio isdependent, in part, upon the performance of otherfunds manged by the Adviser or an affiliate (“OtherFunds”) in which the Portfolio may invest. As a result,the Portfolio is subject to the same risks as those facedby the Other Funds.

Portfolio Turnover Rate Risk. The Portfolio mayengage in active and frequent trading of portfoliosecurities in implementing its principal investmentstrategies. A high rate of portfolio turnover (100% ormore) involves correspondingly greater expenses whichare borne by the Portfolio and its shareholders and mayalso result in short-term capital gains taxable toshareholders.

Preferred Securities Risk. There are certainadditional risks associated with investing in preferredsecurities, including, but not limited to, preferredsecurities may include provisions that permit the issuer,at its discretion, to defer or omit distributions for astated period without any adverse consequences to theissuer; preferred securities are generally subordinated tobonds and other debt instruments in a company’scapital structure in terms of having priority to corporateincome and liquidation payments, and therefore will besubject to greater credit risk than more senior debtinstruments; preferred securities may be substantiallyless liquid than many other securities, such as commonstocks or U.S. Government securities; generally,traditional preferred securities offer no voting rightswith respect to the issuing company unless preferred

dividends have been in arrears for a specified number ofperiods, at which time the preferred security holdersmay elect a number of directors to the issuer’s board;and in certain varying circumstances, an issuer ofpreferred securities may redeem the securities prior to aspecified date.

Real Estate Investment Trust (“REIT”) Risk. REITsgenerally can be divided into three types: equity REITs,mortgage REITs, and hybrid REITs (which combine thecharacteristics of equity REITs and mortgage REITs).Equity REITs will be affected by changes in the values of,and income from, the properties they own, whilemortgage REITs may be affected by the credit quality ofthe mortgage loans they hold. All REIT types may beaffected by changes in interest rates. REITs are subject toadditional risks, including the fact that they aredependent on specialized management skills that mayaffect the REITs’ abilities to generate cash flows foroperating purposes and for making investordistributions. REITs may have limited diversificationand are subject to the risks associated with obtainingfinancing for real property. As with any investment,there is a risk that REIT securities and other real estateindustry investments may be overvalued at the time ofpurchase. In addition, a REIT can pass its incomethrough to its investors without any tax at the entitylevel if it complies with various requirements under theInternal Revenue Code. There is the risk, however, thata REIT held by the Portfolio will fail to qualify for thistax-free pass-through treatment of its income. Inaddition, due to recent changes in the tax laws, certaintax benefits of REITs may not be passed through tomutual fund shareholders. By investing in REITsindirectly through the Portfolio, in addition to bearing aproportionate share of the expenses of the Portfolio, youwill also indirectly bear similar expenses of the REITs inwhich the Portfolio invests.

Sovereign Debt Risk. Sovereign debt securities areissued or guaranteed by foreign governmental entities.These investments are subject to the risk that agovernmental entity may delay or refuse to pay interestor repay principal on its sovereign debt, due, forexample, to cash flow problems, insufficient foreigncurrency reserves, political considerations, the relativesize of the governmental entity’s debt position inrelation to the economy or the failure to put in placeeconomic reforms required by the InternationalMonetary Fund or other multilateral agencies.

Volatility Risk. Volatility risk is the risk that certaintypes of securities shift in and out of favor dependingon market and economic conditions as well as investorsentiment. The value of the Portfolio’s shares may beaffected by weak equity markets or changes in interestrate or bond yield levels. As a result, the value of thePortfolio’s shares may fluctuate significantly in the shortterm.

Effective August 16, 2013, based on approval of thePortfolio’s Board of Directors, the Portfolio’s investmentobjective and principal strategies were changed, whichhad the effect of converting the Portfolio from onewhich invested at least 80% of its assets inincome-producing equity securities to one which investsin a combination of equity securities and debt securities.At the same time, the Portfolio’s name changed fromThrivent Equity Income Plus Portfolio to ThriventGrowth and Income Plus Portfolio. As a result,performance information presented below with respectto periods prior to August 16, 2013, reflects theperformance of an investment portfolio that wasmaterially different from the investment portfolio ofThrivent Growth and Income Plus Portfolio.

The bar chart includes the effects of Portfolio expenses,but not charges or deductions against your variablecontract, and assumes that you sold your investment atthe end of the period. Because shares of the Portfolio areoffered through variable life insurance and variableannuity contracts, you should carefully review thevariable contract prospectus for information onapplicable charges and expenses. If the charges anddeductions against your variable contract were included,returns would be lower than those shown.

How a portfolio has performed in the past is notnecessarily an indication of how it will perform in thefuture. Performance information provides someindication of the risks of investing in the Portfolio byshowing changes in the Portfolio’s performance overtime.

Thrivent High Yield PortfolioInvestment ObjectivesThrivent High Yield Portfolio (the �Portfolio�) seeks toachieve a higher level of income. The Portfolio will alsoconsider growth of capital as a secondary objective.

Fees and ExpensesThis table describes the fees and expenses that you maypay if you buy and hold shares of the Portfolio. If youown a variable annuity contract or variable lifeinsurance contract, you will have additional expensesincluding mortality and expense risk charges. Pleaserefer to the prospectus for your variable contract foradditional information about charges for thosecontracts.

SHAREHOLDER FEES(fees paid directly from your investment)

Maximum Sales Charge (load) Imposed OnPurchases (as a percentage of offering price) N/A

Maximum Deferred Sales Charge (load) (as apercentage of the net asset value at time ofpurchase or redemption, whichever is lower) N/A

ANNUAL PORTFOLIO OPERATING EXPENSES(expenses that you pay each year as a percentage ofthe value of your investment)

Management Fees 0.40%

Other Expenses 0.05%

Total Annual Portfolio Operating Expenses 0.45%

EXAMPLE This example is intended to help youcompare the cost of investing in the Portfolio with thecost of investing in other mutual funds. The Portfolio isan investment option for variable contracts, and theexample does not include charges imposed by variablecontracts. If variable contract charges were imposed,your expenses would be higher than those shown. Theexample assumes that you invest $10,000 in thePortfolio for the time periods indicated and thenredeem all of your shares at the end of those periods.The example also assumes that your investment has a5% return each year, and that the Portfolio’s operatingexpenses remain the same. Although your actual costmay be higher or lower, based on the foregoingassumptions, your cost would be:

Thrivent High YieldPortfolio $46 $144 $252 $567

Portfolio TurnoverThe Portfolio pays transaction costs, such ascommissions, when it buys and sells securities (or “turnsover” its portfolio). A higher portfolio turnover rate mayindicate higher transaction costs and may result inhigher taxes when Portfolio shares are held in a taxableaccount. These costs, which are not reflected in annualfund operating expenses or in the example, affect thePortfolio’s performance. During the most recent fiscalyear, the Portfolio’s portfolio turnover rate was 50% ofthe average value of its portfolio.

Principal StrategiesUnder normal market conditions, the Portfolio investsat least 80% of its net assets (plus the amount of anyborrowing for investment purposes) in high yield, highrisk bonds, notes, debentures and other debt obligations(including leveraged loans, mortgage-backed securities,convertible bonds, and convertible stock), or preferredstocks. These securities are commonly known as “junkbonds.” At the time of purchase these securities arerated within or below the “BB” major rating category byStandard & Poor’s Corporation or the “Ba” major ratingcategory by Moody’s Investor Services, Inc. or areunrated but considered to be of comparable quality bythe Adviser. The Portfolio invests in securities regardlessof the securities’ maturity average and may also investin foreign securities. The Portfolio may also pursue itsinvestment strategy by investing in other mutual funds,including funds managed by the Adviser or an affiliate.Should the Adviser determine that the Portfolio wouldbenefit from reducing the percentage of its assetsinvested in junk bonds from 80% to a lesser amount, wewill notify you at least 60 days prior to the change.

The Adviser uses fundamental, quantitative, andtechnical investment research techniques to determinewhat securities to buy and sell. Fundamental techniquesassess a security’s value based on an issuer’s financialprofile, management, and business prospects whilequantitative and technical techniques involve a moredata-oriented analysis of financial information, markettrends and price movements. The Adviser focuses onU.S. companies which it believes have or are expected toachieve adequate cash flows or access to capital marketsfor the payment of principal and interest obligations.

The Portfolio may utilize derivatives (such as futuresand swaps) for investment exposure or hedgingpurposes, including credit default swap agreements onsecurity indexes. The Portfolio may enter intostandardized derivatives contracts traded on domestic orforeign securities exchanges, boards of trade, or similarentities, and non-standardized derivatives contractstraded in the over-the-counter market.

Principal RisksThe Portfolio is subject to the following principalinvestment risks. Shares of the Portfolio will rise and fallin value and there is a risk that you could lose moneyby investing in the Portfolio. The Portfolio cannot becertain that it will achieve its investment objectives.

Convertible Securities Risk. Convertible securities aresubject to the usual risks associated with debt securities,such as interest rate risk and credit risk. Convertiblesecurities also react to changes in the value of thecommon stock into which they convert, and are thussubject to market risk. The Portfolio may also be forcedto convert a convertible security at an inopportunetime, which may decrease the Portfolio’s return.

Credit Risk. Credit risk is the risk that an issuer of adebt security to which the Portfolio is exposed may nolonger be able or willing to pay its debt. As a result ofsuch an event, the debt security may decline in priceand affect the value of the Portfolio.

Derivatives Risk. The use of derivatives (such asfutures and credit default swaps) involves additionalrisks and transaction costs which could leave thePortfolio in a worse position than if it had not usedthese instruments. The use of derivatives can lead tolosses because of adverse movements in the price orvalue of the underlying asset, index or rate, which maybe magnified by certain features of the contract.Changes in the value of the derivative may not correlateas intended with the underlying asset, rate or index, andthe Portfolio could lose much more than the originalamount invested. Derivatives can be highly volatile,illiquid and difficult to value. Certain derivatives mayalso be subject to counterparty risk, which is that theother party in the transaction will not fulfill itscontractual obligations due to its financial condition,market events, or other reasons.

Foreign Securities Risk. Foreign securities aregenerally more volatile than their domesticcounterparts, in part because of higher political andeconomic risks, lack of reliable information andfluctuations in currency exchange rates. Foreignsecurities may also be more difficult to resell thancomparable U.S. securities because the markets forforeign securities are often less liquid. Even when aforeign security increases in price in its local currency,the appreciation may be diluted by adverse changes inexchange rates when the security’s value is converted toU.S. dollars. Foreign withholding taxes also may applyand errors and delays may occur in the settlementprocess for foreign securities.

High Yield Risk. High yield securities – commonlyknown as “junk bonds” – to which the Portfolio isexposed are considered predominantly speculative withrespect to the issuer’s continuing ability to makeprincipal and interest payments. If the issuer of the

security is in default with respect to interest or principalpayments, the value of the Portfolio may be negativelyaffected.

Interest Rate Risk. Interest rate risk is the risk thatprices of debt securities decline in value when interestrates rise for debt securities that pay a fixed rate ofinterest. Debt securities with longer durations (ameasure of price sensitivity of a bond or bond fund tochanges in interest rates) or maturities (i.e., the amountof time until a bond’s issuer must pay its principal orface value) tend to be more sensitive to changes ininterest rates than debt securities with shorter durationsor maturities. Changes by the Federal Reserve tomonetary policies could affect interest rates and thevalue of some securities.

Investment Adviser Risk. The Portfolio is activelymanaged and the success of its investment strategydepends significantly on the skills of the Adviser inassessing the potential of the investments in which thePortfolio invests. This assessment of investments mayprove incorrect, resulting in losses or poor performance,even in rising markets.

Issuer Risk. Issuer risk is the possibility that factorsspecific to a company to which the Portfolio is exposedwill affect the market prices of the company’s securitiesand therefore the value of the Portfolio.

Leveraged Loan Risk. Leveraged loans (also known asbank loans) are subject to the risks typically associatedwith debt securities. In addition, leveraged loans, whichtypically hold a senior position in the capital structureof a borrower, are subject to the risk that a court couldsubordinate such loans to presently existing or futureindebtedness or take other action detrimental to theholders of leveraged loans. Leveraged loans are alsosubject to the risk that the value of the collateral, if any,securing a loan may decline, be insufficient to meet theobligations of the borrower, or be difficult to liquidate.Some leveraged loans are not as easily purchased or soldas publicly-traded securities and others are illiquid,which may make it more difficult for the Portfolio tovalue them or dispose of them at an acceptable price.Below investment-grade leveraged loans are typicallymore credit sensitive. In the event of fraud ormisrepresentation, the Portfolio may not be protectedunder federal securities laws with respect to leveragedloans that may not be in the form of “securities.” Thesettlement period for some leveraged loans may be morethan seven days.

Liquidity Risk. Liquidity is the ability to sell a securityrelatively quickly for a price that most closely reflectsthe actual value of the security. High-yield bonds andleveraged loans have a less liquid resale market. Inaddition, dealer inventories of bonds are at or nearhistoric lows in relation to market size, which has thepotential to decrease liquidity and increase price

volatility in the fixed income markets, particularlyduring periods of economic or market stress. As a result,the Adviser may have difficulty selling or disposing ofsecurities quickly in certain markets or may only be ableto sell the holdings at prices substantially less than whatthe Adviser believes they are worth.

Market Risk. Over time, securities markets generallytend to move in cycles with periods when securityprices rise and periods when security prices decline. Thevalue of the Portfolio’s investments may move withthese cycles and, in some instances, increase or decreasemore than the applicable market(s) as measured by thePortfolio’s benchmark index(es). The securities marketsmay also decline because of factors that affect aparticular industry.

Other Funds Risk. The performance of the Portfolio isdependent, in part, upon the performance of otherfunds manged by the Adviser or an affiliate (“OtherFunds”) in which the Portfolio may invest. As a result,the Portfolio is subject to the same risks as those facedby the Other Funds.

Preferred Securities Risk. There are certainadditional risks associated with investing in preferredsecurities, including, but not limited to, preferredsecurities may include provisions that permit the issuer,at its discretion, to defer or omit distributions for astated period without any adverse consequences to theissuer; preferred securities are generally subordinated tobonds and other debt instruments in a company’scapital structure in terms of having priority to corporateincome and liquidation payments, and therefore will besubject to greater credit risk than more senior debtinstruments; preferred securities may be substantiallyless liquid than many other securities, such as commonstocks or U.S. Government securities; generally,traditional preferred securities offer no voting rightswith respect to the issuing company unless preferreddividends have been in arrears for a specified number ofperiods, at which time the preferred security holdersmay elect a number of directors to the issuer’s board;and in certain varying circumstances, an issuer ofpreferred securities may redeem the securities prior to aspecified date.

Volatility Risk. Volatility risk is the risk that certaintypes of securities shift in and out of favor dependingon market and economic conditions as well as investorsentiment. The value of the Portfolio’s shares may beaffected by weak equity markets or changes in interestrate or bond yield levels. As a result, the value of thePortfolio’s shares may fluctuate significantly in the shortterm.

PerformanceThe following bar chart and table provide an indicationof the risks of investing in the Portfolio by showingchanges in the Portfolio’s performance from year to year

and by showing how the Portfolio’s average annualreturns for one-, five- and ten-year periods compared toa broad-based securities market index.

Call 800-847-4836 or visitThrivent.com for performance results current to themost recent month-end.

The bar chart and table include the effects of Portfolioexpenses, but not charges or deductions against yourvariable contract, and assume that you sold yourinvestment at the end of the period. Because shares ofthe Portfolio are offered through variable life insuranceand variable annuity contracts, you should carefullyreview the variable contract prospectus for informationon applicable charges and expenses. If the charges anddeductions against your variable contract were included,returns would be lower than those shown.

Portfolio TurnoverThe Portfolio pays transaction costs, such ascommissions, when it buys and sells securities (or “turnsover” its portfolio). A higher portfolio turnover rate mayindicate higher transaction costs and may result inhigher taxes when Portfolio shares are held in a taxableaccount. These costs, which are not reflected in annualfund operating expenses or in the example, affect thePortfolio’s performance.

management technique that includes the purchase andsale of U.S. Treasury securities and related futurescontracts for the purpose of managing the duration ofthe Portfolio. The Portfolio may utilize other derivatives(such as swaps) for investment exposure or hedgingpurposes, including credit default swap agreements onsecurity indexes. The Portfolio may enter intostandardized derivatives contracts traded on domestic orforeign securities exchanges, boards of trade, or similarentities, and non-standardized derivatives contractstraded in the over-the-counter market. The Portfoliomay also pursue its investment strategy by investing inother mutual funds, including funds managed by theAdviser or an affiliate.

The Portfolio may invest in securities of any marketsector and may hold a significant amount of securitiesof companies, from time to time, within a single sectorsuch as financials.

Principal RisksThe Portfolio is subject to the following principalinvestment risks. Shares of the Portfolio will rise and fallin value and there is a risk that you could lose moneyby investing in the Portfolio. The Portfolio cannot becertain that it will achieve its investment objective.

Credit Risk. Credit risk is the risk that an issuer of adebt security to which the Portfolio is exposed may nolonger be able or willing to pay its debt. As a result ofsuch an event, the debt security may decline in priceand affect the value of the Portfolio.

Derivatives Risk. The use of derivatives (such asfutures and credit default swaps) involves additionalrisks and transaction costs which could leave thePortfolio in a worse position than if it had not usedthese instruments. The use of derivatives can lead tolosses because of adverse movements in the price orvalue of the underlying asset, index or rate, which maybe magnified by certain features of the contract.Changes in the value of the derivative may not correlateas intended with the underlying asset, rate or index, andthe Portfolio could lose much more than the originalamount invested. Derivatives can be highly volatile,illiquid and difficult to value. Certain derivatives mayalso be subject to counterparty risk, which is that theother party in the transaction will not fulfill itscontractual obligations due to its financial condition,market events, or other reasons.

Financial Sector Risk. To the extent that thefinancials sector continues to represent a significantportion of the Portfolio, the Portfolio will be sensitive tochanges in, and its performance may depend to agreater extent on, factors impacting this sector.Performance of companies in the financials sector maybe adversely impacted by many factors, including,among others, government regulations, economicconditions, credit rating downgrades, changes in

interest rates, and decreased liquidity in credit markets.The impact of more stringent capital requirements,recent or future regulation of any individual financialcompany or recent or future regulation of the financialssector as a whole cannot be predicted. In recent years,cyber attacks and technology malfunctions and failureshave become increasingly frequent in this sector andhave caused significant losses.

Foreign Securities Risk. To the extent the Portfolio isexposed to foreign securities, it is subject to various risksassociated with such securities. Foreign securities aregenerally more volatile than their domesticcounterparts, in part because of higher political andeconomic risks, lack of reliable information andfluctuations in currency exchange rates. Foreignsecurities may also be more difficult to resell thancomparable U.S. securities because the markets forforeign securities are often less liquid. Even when aforeign security increases in price in its local currency,the appreciation may be diluted by adverse changes inexchange rates when the security’s value is converted toU.S. dollars. Foreign withholding taxes also may applyand errors and delays may occur in the settlementprocess for foreign securities.

High Yield Risk. High yield securities – commonlyknown as “junk bonds” – to which the Portfolio isexposed are considered predominantly speculative withrespect to the issuer’s continuing ability to makeprincipal and interest payments. If the issuer of thesecurity is in default with respect to interest or principalpayments, the value of the Portfolio may be negativelyaffected.

Interest Rate Risk. Interest rate risk is the risk thatprices of debt securities decline in value when interestrates rise for debt securities that pay a fixed rate ofinterest. Debt securities with longer durations (ameasure of price sensitivity of a bond or bond fund tochanges in interest rates) or maturities (i.e., the amountof time until a bond’s issuer must pay its principal orface value) tend to be more sensitive to changes ininterest rates than debt securities with shorter durationsor maturities. In addition, both mortgage-backed andasset-backed securities are sensitive to changes in therepayment patterns of the underlying security. If theprincipal payment on the underlying asset is repaidfaster or slower than the holder of the asset-backed ormortgage-backed security anticipates, the price of thesecurity may fall, particularly if the holder must reinvestthe repaid principal at lower rates or must continue tohold the security when interest rates rise. This effectmay cause the value of the Portfolio to decline andreduce the overall return of the Portfolio. Changes bythe Federal Reserve to monetary policies could affectinterest rates and the value of some securities.

depends significantly on the skills of the Adviser inassessing the potential of the investments in which thePortfolio invests. This assessment of investments mayprove incorrect, resulting in losses or poor performance,even in rising markets.

Issuer Risk. Issuer risk is the possibility that factorsspecific to a company to which the Portfolio is exposedwill affect the market prices of the company’s securitiesand therefore the value of the Portfolio.

Leveraged Loan Risk. Leveraged loans (also known asbank loans) are subject to the risks typically associatedwith debt securities. In addition, leveraged loans, whichtypically hold a senior position in the capital structureof a borrower, are subject to the risk that a court couldsubordinate such loans to presently existing or futureindebtedness or take other action detrimental to theholders of leveraged loans. Leveraged loans are alsosubject to the risk that the value of the collateral, if any,securing a loan may decline, be insufficient to meet theobligations of the borrower, or be difficult to liquidate.Some leveraged loans are not as easily purchased or soldas publicly-traded securities and others are illiquid,which may make it more difficult for the Portfolio tovalue them or dispose of them at an acceptable price.Below investment-grade leveraged loans are typicallymore credit sensitive. In the event of fraud ormisrepresentation, the Portfolio may not be protectedunder federal securities laws with respect to leveragedloans that may not be in the form of “securities.” Thesettlement period for some leveraged loans may be morethan seven days.

Liquidity Risk. Liquidity is the ability to sell a securityrelatively quickly for a price that most closely reflectsthe actual value of the security. Inventories of bonds areat or near historic lows in relation to market size, whichhas the potential to decrease liquidity and increase pricevolatility in the fixed income markets, particularlyduring periods of economic or market stress. As a resultof this decreased liquidity, the Adviser may have toaccept a lower price to sell a security, sell other securitiesto raise cash, or give up an investment opportunity, anyof which could have a negative effect on performance.

Market Risk. Over time, securities markets generallytend to move in cycles with periods when securityprices rise and periods when security prices decline. Thevalue of the Portfolio’s investments may move withthese cycles and, in some instances, increase or decreasemore than the applicable market(s) as measured by thePortfolio’s benchmark index(es). The securities marketsmay also decline because of factors that affect aparticular industry.

Mortgage-Related and Other Asset-BackedSecurities Risk. The value of mortgage-related andasset-backed securities will be influenced by the factorsaffecting the housing market and the assets underlying

such securities. As a result, during periods of decliningasset value, difficult or frozen credit markets, swings ininterest rates, or deteriorating economic conditions,mortgage-related and asset-backed securities maydecline in value, face valuation difficulties, becomemore volatile and/or become illiquid.

Other Funds Risk. The performance of the Portfolio isdependent, in part, upon the performance of otherfunds manged by the Adviser or an affiliate (“OtherFunds”) in which the Portfolio may invest. As a result,the Portfolio is subject to the same risks as those facedby the Other Funds.

Portfolio Turnover Rate Risk. The Portfolio mayengage in active and frequent trading of portfoliosecurities in implementing its principal investmentstrategies. A high rate of portfolio turnover (100% ormore) involves correspondingly greater expenses whichare borne by the Portfolio and its shareholders and mayalso result in short-term capital gains taxable toshareholders.

Preferred Securities Risk. There are certainadditional risks associated with investing in preferredsecurities, including, but not limited to, preferredsecurities may include provisions that permit the issuer,at its discretion, to defer or omit distributions for astated period without any adverse consequences to theissuer; preferred securities are generally subordinated tobonds and other debt instruments in a company’scapital structure in terms of having priority to corporateincome and liquidation payments, and therefore will besubject to greater credit risk than more senior debtinstruments; preferred securities may be substantiallyless liquid than many other securities, such as commonstocks or U.S. Government securities; generally,traditional preferred securities offer no voting rightswith respect to the issuing company unless preferreddividends have been in arrears for a specified number ofperiods, at which time the preferred security holdersmay elect a number of directors to the issuer’s board;and in certain varying circumstances, an issuer ofpreferred securities may redeem the securities prior to aspecified date.

Volatility Risk. Volatility risk is the risk that certaintypes of securities shift in and out of favor dependingon market and economic conditions as well as investorsentiment. Bonds may exhibit price fluctuations due tochanges in interest rates or bond yield levels.

Thrivent Large Cap Growth PortfolioInvestment ObjectiveThe investment objective of Thrivent Large Cap GrowthPortfolio (the �Portfolio�) is to achieve long-term growthof capital.

Fees and ExpensesThis table describes the fees and expenses that you maypay if you buy and hold shares of the Portfolio. If youown a variable annuity contract or variable lifeinsurance contract, you will have additional expensesincluding mortality and expense risk charges. Pleaserefer to the prospectus for your variable contract foradditional information about charges for thosecontracts.

SHAREHOLDER FEES(fees paid directly from your investment)

Maximum Sales Charge (load) Imposed OnPurchases (as a percentage of offering price) N/A

Maximum Deferred Sales Charge (load) (as apercentage of the net asset value at time ofpurchase or redemption, whichever is lower) N/A

ANNUAL PORTFOLIO OPERATING EXPENSES(expenses that you pay each year as a percentage ofthe value of your investment)

EXAMPLE This example is intended to help youcompare the cost of investing in the Portfolio with thecost of investing in other mutual funds. The Portfolio isan investment option for variable contracts, and theexample does not include charges imposed by variablecontracts. If variable contract charges were imposed,your expenses would be higher than those shown. Theexample assumes that you invest $10,000 in thePortfolio for the time periods indicated and thenredeem all of your shares at the end of those periods.The example also assumes that your investment has a5% return each year, and that the Portfolio’s operatingexpenses remain the same. Although your actual costmay be higher or lower, based on the foregoingassumptions, your cost would be:

1 Year 3 Years 5 Years 10 Years

Thrivent Large CapGrowth Portfolio $45 $141 $246 $555

Portfolio TurnoverThe Portfolio pays transaction costs, such ascommissions, when it buys and sells securities (or “turnsover” its portfolio). A higher portfolio turnover rate mayindicate higher transaction costs and may result inhigher taxes when Portfolio shares are held in a taxableaccount. These costs, which are not reflected in annualfund operating expenses or in the example, affect thePortfolio’s performance. During the most recent fiscalyear, the Portfolio’s portfolio turnover rate was 59% ofthe average value of its portfolio.

Principal StrategiesUnder normal circumstances, the Portfolio invests atleast 80% of its net assets (plus the amount of anyborrowing for investment purposes) in equity securitiesof large companies. The Adviser focuses mainly on theequity securities of large domestic and internationalcompanies which have market capitalizationsequivalent to those included in widely known indicessuch as the S&P 500 Index, the MSCI USA Large CapIndex, or the large company market capitalizationclassifications published by Lipper, Inc. Thesecompanies typically have a market capitalization ofapproximately $8 billion or more. Should the Adviserdetermine that the Portfolio would benefit fromreducing the percentage of its assets invested in equitysecurities of large cap companies from 80% to a lesseramount, we will notify you at least 60 days prior to thechange.

The Portfolio seeks to achieve its investment objectiveby investing in common stocks. The Adviser usesfundamental, quantitative, and technical investmentresearch techniques and focuses on stocks of companiesthat it believes have demonstrated and will sustainabove-average earnings growth over time, or which areexpected to develop rapid sales and earnings growth inthe future when compared to the economy and stockmarket as a whole. Many such companies are in thetechnology sector and the Portfolio may at times have ahigher concentration in this industry.

The Portfolio may also pursue its investment strategy byinvesting in other mutual funds, including fundsmanaged by the Adviser or an affiliate. The Portfoliomay sell securities for a variety of reasons, such as tosecure gains, limit losses, or reposition assets into morepromising opportunities.

Principal RisksThe Portfolio is subject to the following principalinvestment risks. Shares of the Portfolio will rise and fallin value and there is a risk that you could lose money

by investing in the Portfolio. The Portfolio cannot becertain that it will achieve its investment objective.

Foreign Securities Risk. Foreign securities aregenerally more volatile than their domesticcounterparts, in part because of higher political andeconomic risks, lack of reliable information andfluctuations in currency exchange rates. Foreignsecurities may also be more difficult to resell thancomparable U.S. securities because the markets forforeign securities are often less liquid. Even when aforeign security increases in price in its local currency,the appreciation may be diluted by adverse changes inexchange rates when the security’s value is converted toU.S. dollars. Foreign withholding taxes also may applyand errors and delays may occur in the settlementprocess for foreign securities.

Growth Investing Risk. Growth style investingincludes the risk of investing in securities whose priceshistorically have been more volatile than othersecurities, especially over the short term. Growth stockprices reflect projections of future earnings or revenuesand, if a company’s earnings or revenues fall short ofexpectations, its stock price may fall dramatically.

Investment Adviser Risk. The Portfolio is activelymanaged and the success of its investment strategydepends significantly on the skills of the Adviser inassessing the potential of the investments in which thePortfolio invests. This assessment of investments mayprove incorrect, resulting in losses or poor performance,even in rising markets.

Issuer Risk. Issuer risk is the possibility that factorsspecific to a company to which the Portfolio is exposedwill affect the market prices of the company’s securitiesand therefore the value of the Portfolio. Some factorsaffecting the performance of a company includedemand for the company’s products or services, thequality of management of the company and brandrecognition and loyalty.

Large Cap Risk. Large-sized companies may be unableto respond quickly to new competitive challenges suchas changes in technology. They may also not be able toattain the high growth rate of successful smallercompanies, especially during extended periods ofeconomic expansion.

Market Risk. Over time, securities markets generallytend to move in cycles with periods when securityprices rise and periods when security prices decline. Thevalue of the Portfolio’s investments may move withthese cycles and, in some instances, increase or decreasemore than the applicable market(s) as measured by thePortfolio’s benchmark index(es). The securities marketsmay also decline because of factors that affect aparticular industry.

Other Funds Risk. The performance of the Portfolio isdependent, in part, upon the performance of otherfunds manged by the Adviser or an affiliate (“OtherFunds”) in which the Portfolio may invest. As a result,the Portfolio is subject to the same risks as those facedby the Other Funds.

Technology-Oriented Companies Risk. Commonstocks of companies that rely extensively on technology,science or communications in their productdevelopment or operations may be more volatile thanthe overall stock market and may or may not move intandem with the overall stock market. Technology,science and communications are rapidly changingfields, and stocks of these companies, especially ofsmaller or unseasoned companies, may be subject tomore abrupt or erratic market movements than thestock market in general. There are significantcompetitive pressures among technology-orientedcompanies and the products or operations of suchcompanies may become obsolete quickly. In addition,these companies may have limited product lines,markets or financial resources and the management ofsuch companies may be more dependent upon one or afew key people.

Volatility Risk. Volatility risk is the risk that certaintypes of securities shift in and out of favor dependingon market and economic conditions as well as investorsentiment. Growth style investing includes the risk ofinvesting in securities whose prices historically havebeen more volatile than other securities, especially overthe short term. Growth stock prices reflect projection offuture earnings or revenues and, if a company’s earningsor revenues fall short of expectations, its stock pricemay fall dramatically.

Portfolio TurnoverThe Portfolio pays transaction costs, such ascommissions, when it buys and sells securities (or “turnsover” its portfolio). A higher portfolio turnover rate mayindicate higher transaction costs and may result inhigher taxes when Portfolio shares are held in a taxableaccount. These costs, which are not reflected in annualfund operating expenses or in the example, affect thePortfolio’s performance. During the most recent fiscalyear, the Portfolio’s portfolio turnover rate was 3% ofthe average value of its portfolio.

Principal StrategiesUnder normal circumstances, the Portfolio investssubstantially all of its assets (more than 80% of its netassets, plus the amount of any borrowings forinvestment purposes) in the large company commonstocks included in the S&P 500 Index in the proportionsin which they are represented in the index. This is apassively managed Portfolio, which means that theAdviser does not actively choose the securities thatshould make up the Portfolio. The S&P 500 Index iscomprised of 500 domestic large company stocks.Accordingly, the Portfolio invests in stocks of largercompanies from a broad range of industries. The S&P500 Index is adjusted quarterly, and when changes tothe index occur, the Adviser will attempt to replicatethese changes within the Portfolio. However, any suchchanges may result in slight variations from time totime. The Portfolio may buy and sell equity indexfutures for investment exposure. For liquidity reasons,the Portfolio may invest to some degree in moneymarket instruments. The Portfolio may also pursue itsinvestment strategy by investing in other mutual funds,including funds managed by the Adviser or an affiliate.

Principal RisksThe Portfolio is subject to the following principalinvestment risks. Shares of the Portfolio will rise and fallin value and there is a risk that you could lose moneyby investing in the Portfolio. The Portfolio cannot becertain that it will achieve its investment objective.

Futures Contract Risk. The value of a futurescontract tends to increase and decrease in tandem withthe value of the underlying instrument. The price offutures can be highly volatile; using them could lowertotal return, and the potential loss from futures canexceed the Portfolio’s initial investment in suchcontracts. In addition, the value of the futures contractmay not accurately track the value of the underlyinginstrument.

Issuer Risk. Issuer risk is the possibility that factorsspecific to a company to which the Portfolio is exposed

will affect the market prices of the company’s securitiesand therefore the value of the Portfolio. Common stockof a company is subordinate to other securities issued bythe company. If a company becomes insolvent, interestsof investors owning common stock will be subordinatedto the interests of other investors in, and generalcreditors of, the company.

1 Year 3 Years 5 Years 10 Years

Thrivent Large CapStock Portfolio $67 $211 $368 $822

Portfolio TurnoverThe Portfolio pays transaction costs, such ascommissions, when it buys and sells securities (or “turns

over” its portfolio). A higher portfolio turnover rate mayindicate higher transaction costs and may result inhigher taxes when Portfolio shares are held in a taxableaccount. These costs, which are not reflected in annualfund operating expenses or in the example, affect thePortfolio’s performance. During the most recent fiscalyear, the Portfolio’s portfolio turnover rate was 59% ofthe average value of its portfolio.

Principal StrategiesUnder normal circumstances, the Portfolio invests atleast 80% of its net assets (plus the amount of anyborrowing for investment purposes) in equity securitiesof large companies. The Adviser focuses mainly on theequity securities of large domestic and internationalcompanies which have market capitalizationsequivalent to those in widely known indices such as theS&P 500 Index, the MSCI USA Large Cap Index, or thelarge company market capitalization classificationspublished by Lipper, Inc. These companies typicallyhave a market capitalization of approximately $8 billionor more. Should the Adviser determine that thePortfolio would benefit from reducing the percentage ofits assets invested in equity securities of large capcompanies from 80% to a lesser amount, we will notifyyou at least 60 days prior to the change.

The Portfolio seeks to achieve its investment objectiveby investing primarily in domestic and internationalcommon stocks. The Portfolio may buy and sell futurescontracts to either hedge its exposure or obtainexposure to certain investments. The Portfolio may alsopursue its investment strategy by investing in othermutual funds, including funds managed by the Adviseror an affiliate. The Adviser uses fundamental,quantitative, and technical investment researchtechniques to determine what stocks to buy and sell.Fundamental techniques assess a security’s value basedon an issuer’s financial profile, management, andbusiness prospects while quantitative and technicaltechniques involve a more data-oriented analysis offinancial information, market trends and pricemovements. The Portfolio may sell securities for avariety of reasons, such as to secure gains, limit losses,or reposition assets into more promising opportunities.

Principal RisksThe Portfolio is subject to the following principalinvestment risks. Shares of the Portfolio will rise and fallin value and there is a risk that you could lose moneyby investing in the Portfolio. The Portfolio cannot becertain that it will achieve its investment objective.

Foreign Securities Risk. Foreign securities aregenerally more volatile than their domestic

Page 96: Single Premium Immediate Variable Annuity · PDF fileSingle Premium Immediate Variable Annuity Issued between 7/26/1999 and 4/29/2016. Prospectuses April 30, 2017 Thrivent Variable

counterparts, in part because of higher political andeconomic risks, lack of reliable information andfluctuations in currency exchange rates. Foreignsecurities may also be more difficult to resell thancomparable U.S. securities because the markets forforeign securities are often less liquid. Even when aforeign security increases in price in its local currency,the appreciation may be diluted by adverse changes inexchange rates when the security’s value is converted toU.S. dollars. Foreign withholding taxes also may applyand errors and delays may occur in the settlementprocess for foreign securities.

Futures Contract Risk. The value of a futurescontract tends to increase and decrease in tandem withthe value of the underlying instrument. The price offutures can be highly volatile; using them could lowertotal return, and the potential loss from futures canexceed the Portfolio’s initial investment in suchcontracts. In addition, the value of the futures contractmay not accurately track the value of the underlyinginstrument.

Investment Adviser Risk. The Portfolio is activelymanaged and the success of the Portfolio’s investmentstrategy depends significantly on the skills of theAdviser in assessing the potential of the investments inwhich the Portfolio invests. This assessment ofinvestments may prove incorrect, resulting in losses orpoor performance, even in rising markets.

Issuer Risk. Issuer risk is the possibility that factorsspecific to a company to which the Portfolio is exposedwill affect the market prices of the company’s securitiesand therefore the value of the Portfolio. Some factorsaffecting the performance of a company includedemand for the company’s products or services, thequality of management of the company and brandrecognition and loyalty. Common stock of a company issubordinate to other securities issued by the company. Ifa company becomes insolvent, interests of investorsowning common stock will be subordinated to theinterests of other investors in, and general creditors of,the company.

Large Cap Risk. Large-sized companies may be unableto respond quickly to new competitive challenges suchas changes in technology. They may also not be able toattain the high growth rate of successful smallercompanies, especially during extended periods ofeconomic expansion.

Market Risk. Over time, securities markets generallytend to move in cycles with periods when securityprices rise and periods when security prices decline. Thevalue of the Portfolio’s investments may move withthese cycles and, in some instances, increase or decreasemore than the applicable market(s) as measured by thePortfolio’s benchmark index(es). The securities markets

may also decline because of factors that affect aparticular industry.

Other Funds Risk. The performance of the Portfolio isdependent, in part, upon the performance of otherfunds manged by the Adviser or an affiliate (“OtherFunds”) in which the Portfolio may invest. As a result,the Portfolio is subject to the same risks as those facedby the Other Funds.

Volatility Risk. Volatility risk is the risk that certaintypes of securities shift in and out of favor dependingon market and economic conditions as well as investorsentiment.

PerformanceThe following bar chart and table provide an indicationof the risks of investing in the Portfolio by showingchanges in the Portfolio’s performance from year to yearand by showing how the Portfolio’s average annualreturns for one-, five-, and ten-year periods compared toa broad-based securities market index.

focuses on companies that it believes are financiallysound and have strong cash flow, asset values andinterest or dividend earnings. Some of these companiesmay be foreign ones. Additionally, the Portfolio mayinvest in leveraged loans, which are senior secured loansthat are made by banks or other lending institutions tocompanies that are rated below investment grade. Pleasenote that the Portfolio will likely use an interest ratemanagement technique that includes the purchase andsale of U.S. Treasury securities and related futurescontracts for the purpose of managing the duration ofthe Portfolio. The Portfolio may utilize other derivatives(such as swaps) for investment exposure or hedgingpurposes, including credit default swap agreements onsecurity indexes. The Portfolio may enter intostandardized derivatives contracts traded on domestic orforeign securities exchanges, boards of trade, or similarentities, and non-standardized derivatives contractstraded in the over-the-counter market. The Portfoliomay also pursue its investment strategy by investing inother mutual funds, including funds managed by theAdviser or an affiliate.

Principal RisksThe Portfolio is subject to the following principalinvestment risks. Shares of the Portfolio will rise and fallin value and there is a risk that you could lose moneyby investing in the Portfolio. The Portfolio cannot becertain that it will achieve its investment objective.

Collateralized Debt Obligations Risk. The risks ofan investment in a collateralized debt obligation(“CDO”) depend largely on the quality and type of thecollateral and the tranche of the CDO in which thePortfolio invests. In addition to the typical risksassociated with fixed income securities and asset-backedsecurities, CDOs carry additional risks including, butnot limited to: (i) the possibility that distributions fromcollateral securities will not be adequate to makeinterest or other payments; (ii) the risk that thecollateral may default, decline in value, and/or bedowngraded; (iii) the Portfolio may invest in tranches ofCDOs that are subordinate to other tranches; (iv) thestructure and complexity of the transaction and thelegal documents could lead to disputes among investorsregarding the characterization of proceeds; (v) theinvestment return achieved by the Portfolio could besignificantly different than those predicted by financialmodels; (vi) the lack of a readily available secondarymarket for CDOs; (vii) risk of forced “fire sale”liquidation due to technical defaults such as coveragetest failures; and (viii) the CDO’s manager may performpoorly.

Credit Risk. Credit risk is the risk that an issuer of adebt security to which the Portfolio is exposed may nolonger be able or willing to pay its debt. As a result ofsuch an event, the debt security may decline in priceand affect the value of the Portfolio.

Derivatives Risk. The use of derivatives (such asfutures and credit default swaps) involves additionalrisks and transaction costs which could leave thePortfolio in a worse position than if it had not usedthese instruments. The use of derivatives can lead tolosses because of adverse movements in the price orvalue of the underlying asset, index or rate, which maybe magnified by certain features of the contract.Changes in the value of the derivative may not correlateas intended with the underlying asset, rate or index, andthe Portfolio could lose much more than the originalamount invested. Derivatives can be highly volatile,illiquid and difficult to value. Certain derivatives mayalso be subject to counterparty risk, which is that theother party in the transaction will not fulfill itscontractual obligations due to its financial condition,market events, or other reasons.

Foreign Securities Risk. Foreign securities aregenerally more volatile than their domesticcounterparts, in part because of higher political andeconomic risks, lack of reliable information andfluctuations in currency exchange rates. Foreignsecurities may also be more difficult to resell thancomparable U.S. securities because the markets forforeign securities are often less liquid. Even when aforeign security increases in price in its local currency,the appreciation may be diluted by adverse changes inexchange rates when the security’s value is converted toU.S. dollars. Foreign withholding taxes also may applyand errors and delays may occur in the settlementprocess for foreign securities.

High Yield Risk. High yield securities – commonlyknown as “junk bonds” – to which the Portfolio isexposed are considered predominantly speculative withrespect to the issuer’s continuing ability to makeprincipal and interest payments. If the issuer of thesecurity is in default with respect to interest or principalpayments, the value of the Portfolio may be negativelyaffected.

Interest Rate Risk. Interest rate risk is the risk thatprices of debt securities decline in value when interestrates rise for debt securities that pay a fixed rate ofinterest. In addition, both mortgage-backed andasset-backed securities are sensitive to changes in therepayment patterns of the underlying security. If theprincipal payment on the underlying asset is repaidfaster or slower than the holder of the asset-backed ormortgage-backed security anticipates, the price of thesecurity may fall, particularly if the holder must reinvestthe repaid principal at lower rates or must continue tohold the security when interest rates rise. This effectmay cause the value of the Portfolio to decline andreduce the overall return of the Portfolio. Changes bythe Federal Reserve to monetary policies could affectinterest rates and the value of some securities.

Investment Adviser Risk. The Portfolio is activelymanaged and the success of its investment strategydepends significantly on the skills of the Adviser inassessing the potential of the investments in which thePortfolio invests. This assessment of investments mayprove incorrect, resulting in losses or poor performance,even in rising markets.

Issuer Risk. Issuer risk is the possibility that factorsspecific to a company to which the Portfolio is exposedwill affect the market prices of the company’s securitiesand therefore the value of the Portfolio.

Leveraged Loan Risk. Leveraged loans (also known asbank loans) are subject to the risks typically associatedwith debt securities. In addition, leveraged loans, whichtypically hold a senior position in the capital structureof a borrower, are subject to the risk that a court couldsubordinate such loans to presently existing or futureindebtedness or take other action detrimental to theholders of leveraged loans. Leveraged loans are alsosubject to the risk that the value of the collateral, if any,securing a loan may decline, be insufficient to meet theobligations of the borrower, or be difficult to liquidate.Some leveraged loans are not as easily purchased or soldas publicly-traded securities and others are illiquid,which may make it more difficult for the Portfolio tovalue them or dispose of them at an acceptable price.Below investment-grade leveraged loans are typicallymore credit sensitive. In the event of fraud ormisrepresentation, the Portfolio may not be protectedunder federal securities laws with respect to leveragedloans that may not be in the form of “securities.” Thesettlement period for some leveraged loans may be morethan seven days.

Liquidity Risk. Liquidity is the ability to sell a securityrelatively quickly for a price that most closely reflectsthe actual value of the security. Inventories of bonds areat or near historic lows in relation to market size, whichhas the potential to decrease liquidity and increase pricevolatility in the fixed income markets, particularlyduring periods of economic or market stress. As a resultof this decreased liquidity, the Adviser may have toaccept a lower price to sell a security, sell other securitiesto raise cash, or give up an investment opportunity, anyof which could have a negative effect on performance.

Market Risk. Over time, securities markets generallytend to move in cycles with periods when securityprices rise and periods when security prices decline. Thevalue of the Portfolio’s investments may move withthese cycles and, in some instances, increase or decreasemore than the applicable market(s) as measured by thePortfolio’s benchmark index(es). The securities marketsmay also decline because of factors that affect aparticular industry.

Mortgage-Related and Other Asset-BackedSecurities Risk. The value of mortgage-related and

asset-backed securities will be influenced by the factorsaffecting the housing market and the assets underlyingsuch securities. As a result, during periods of decliningasset value, difficult or frozen credit markets, swings ininterest rates, or deteriorating economic conditions,mortgage-related and asset-backed securities maydecline in value, face valuation difficulties, becomemore volatile and/or become illiquid.

Other Funds Risk. The performance of the Portfolio isdependent, in part, upon the performance of otherfunds manged by the Adviser or an affiliate (“OtherFunds”) in which the Portfolio may invest. As a result,the Portfolio is subject to the same risks as those facedby the Other Funds.

Preferred Securities Risk. There are certainadditional risks associated with investing in preferredsecurities, including, but not limited to, preferredsecurities may include provisions that permit the issuer,at its discretion, to defer or omit distributions for astated period without any adverse consequences to theissuer; preferred securities are generally subordinated tobonds and other debt instruments in a company’scapital structure in terms of having priority to corporateincome and liquidation payments, and therefore will besubject to greater credit risk than more senior debtinstruments; preferred securities may be substantiallyless liquid than many other securities, such as commonstocks or U.S. Government securities; generally,traditional preferred securities offer no voting rightswith respect to the issuing company unless preferreddividends have been in arrears for a specified number ofperiods, at which time the preferred security holdersmay elect a number of directors to the issuer’s board;and in certain varying circumstances, an issuer ofpreferred securities may redeem the securities prior to aspecified date.

Volatility Risk. Volatility risk is the risk that certaintypes of securities shift in and out of favor dependingon market and economic conditions as well as investorsentiment. Bonds may exhibit price fluctuations due tochanges in interest rates or bond yield levels.

2 The Adviser has contractually agreed, through at least April 30,2019, to waive certain fees and/or reimburse certain expensesassociated with the shares of the Thrivent Low Volatility Portfolioin order to limit the Total Annual Portfolio Operating ExpensesAfter Fee Waivers and/or Expense Reimbursements, if any, to anannual rate of 0.80% of the average daily net assets of the shares.This contractual provision, however, may be terminated before theindicated termination date upon the mutual agreement betweenthe Independent Directors of the Portfolio and the Adviser.

EXAMPLE This example is intended to help youcompare the cost of investing in the Portfolio with thecost of investing in other mutual funds. The Portfolio isan investment option for variable contracts, and theexample does not include charges imposed by variablecontracts.

redeem all of your shares at the end of those periods. Inaddition, the example for the 1 Year period reflects theeffect of the contractual fee waiver and/or expensereimbursement. The example also assumes that yourinvestment has a 5% return each year, and that thePortfolio’s operating expenses remain the same.Although your actual cost may be higher or lower, basedon the foregoing assumptions, your cost would be:

1 Year 3 Years 5 Years 10 Years

Thrivent LowVolatility EquityPortfolio $82 $732 $1,407 $3,215

Portfolio TurnoverThe Portfolio pays transaction costs, such ascommissions, when it buys and sells securities (or “turnsover” its portfolio). A higher portfolio turnover rate mayindicate higher transaction costs and may result inhigher taxes when Portfolio shares are held in a taxableaccount. These costs, which are not reflected in annualfund operating expenses or in the example, affect thePortfolio’s performance.

From inception on April 28, 2017 through the mostrecent fiscal year, the Portfolio’s portfolio turnover ratewas 35% of the average value of its portfolio.

Principal StrategiesUnder normal circumstances, the Portfolio invests atleast 80% of its net assets (plus the amount of anyborrowing for investment purposes) in equity securities.The Portfolio’s investments are diversified globally. ThePortfolio may invest in securities denominated in U.S.dollars and the currencies of the foreign countries inwhich it may invest. The Portfolio typically has fullcurrency exposure to those markets in which it invests.The Portfolio may buy or sell equity index futures forinvestment exposure or hedging purposes. The Portfoliomay invest in securities of any market capitalization,including small- and mid-cap securities. The Portfoliomay also pursue its investment strategy by investing inother mutual funds, including funds managed by theAdviser or an affiliate.

In seeking to achieve the Portfolio’s investmentobjective, the Adviser employs investment managementtechniques to identify securities that exhibit lowvolatility returns. Volatility refers to the variation insecurity and market prices over time. Over a full marketcycle, the Portfolio seeks to produce returns similar tothe MSCI World Index but with less volatility. It isexpected that the Portfolio will generally underperformthe global equity markets during periods of strongmarket performance.

In buying and selling securities for the Portfolio, theAdviser uses an active strategy. This strategy consists of adisciplined approach that involves computer-aided,quantitative analysis of fundamental, technical andrisk-related factors. The Adviser’s factor model (amethod of analyzing and combining multiple datasources) systematically reviews thousands of stocks,using data such as historical earnings growth andexpected future growth, valuation, price momentum,and other quantitative factors to forecast returnpotential. Then, risk characteristics of potentialinvestments and covariation among securities areanalyzed along with the return forecasts in determiningthe Portfolio’s holdings to produce a portfolio withreduced volatility.

Principal RisksThe Portfolio is subject to the following principalinvestment risks. Shares of the Portfolio will rise and fallin value and there is a risk that you could lose moneyby investing in the Portfolio. The Portfolio cannot becertain that it will achieve its investment objective.

Foreign Securities Risk. Foreign securities aregenerally more volatile than their domesticcounterparts, in part because of higher political andeconomic risks, lack of reliable information andfluctuations in currency exchange rates. Foreignsecurities may also be more difficult to resell thancomparable U.S. securities because the markets forforeign securities are often less liquid. Even when aforeign security increases in price in its local currency,the appreciation may be diluted by adverse changes inexchange rates when the security’s value is converted toU.S. dollars. Foreign withholding taxes also may applyand errors and delays may occur in the settlementprocess for foreign securities.

Futures Contract Risk. The value of a futurescontract tends to increase and decrease in tandem withthe value of the underlying instrument. The price offutures can be highly volatile; using them could lowertotal return, and the potential loss from futures canexceed the Portfolio’s initial investment in suchcontracts. In addition, the value of the futures contractmay not accurately track the value of the underlyinginstrument.

Investment Adviser Risk. The Portfolio is activelymanaged and the success of its investment strategydepends significantly on the skills of the Adviser inassessing the potential of the investments in which thePortfolio invests. This assessment of investments mayprove incorrect, resulting in losses or poor performance,even in rising markets.

Issuer Risk. Issuer risk is the possibility that factorsspecific to a company to which the Portfolio is exposedwill affect the market prices of the company’s securitiesand therefore the value of the Portfolio.

Large Cap Risk. Large-sized companies may be unableto respond quickly to new competitive challenges suchas changes in technology. They may also not be able toattain the high growth rate of successful smallercompanies, especially during extended periods ofeconomic expansion.

Market Risk. Over time, securities markets generallytend to move in cycles with periods when securityprices rise and periods when security prices decline. Thevalue of the Portfolio’s investments may move withthese cycles and, in some instances, increase or decreasemore than the applicable market(s) as measured by thePortfolio’s benchmark index(es). The securities marketsmay also decline because of factors that affect aparticular industry.

Other Funds Risk. The performance of the Portfolio isdependent, in part, upon the performance of otherfunds manged by the Adviser or an affiliate (“OtherFunds”) in which the Portfolio may invest. As a result,the Portfolio is subject to the same risks as those facedby the Other Funds.

Small and Mid Cap Risk. Small- and medium-sizedcompanies often have greater price volatility, lowertrading volumes, and less liquidity than larger, moreestablished companies. These companies tend to havesmaller revenues, narrower product lines, lessmanagement depth and experience, smaller shares oftheir product or service markets, fewer financialresources, and less competitive strength than largercompanies.

Volatility Risk. Although the Portfolio seeks lowervolatility than the global equity markets, its returns willexperience some volatility. Volatility risk is the risk thatcertain types of securities shift in and out of favordepending on market and economic conditions as wellas investor sentiment. The value of the Portfolio’s sharesmay be affected by weak equity markets. As a result, thevalue of the Portfolio’s shares may fluctuatesignificantly in the short term.

The S&P MidCap 400Index is a capitalization weighted index of 400 mediumcapitalization stocks chosen for market size, liquidity,and industry representation. Accordingly, the Portfolioinvests in stocks of medium-sized companies from abroad range of industries. The S&P MidCap 400 Index isadjusted quarterly and when changes to the indexoccur, the Adviser will attempt to replicate thesechanges within the Portfolio. However, any suchchanges may result in slight variations from the index.The Portfolio may buy and sell equity index futures forinvestment exposure.

Issuer Risk. Issuer risk is the possibility that factorsspecific to a company to which the Portfolio is exposedwill affect the market prices of the company’s securitiesand therefore the value of the Portfolio.

Thrivent Mid Cap Stock PortfolioInvestment ObjectiveThrivent Mid Cap Stock Portfolio (the �Portfolio�) seekslong-term capital growth.

Fees and ExpensesThis table describes the fees and expenses that you maypay if you buy and hold shares of the Portfolio. If youown a variable annuity contract or variable lifeinsurance contract, you will have additional expensesincluding mortality and expense risk charges. Pleaserefer to the prospectus for your variable contract foradditional information about charges for thosecontracts.

SHAREHOLDER FEES(fees paid directly from your investment)

Maximum Sales Charge (load) Imposed OnPurchases (as a percentage of offering price) N/A

Maximum Deferred Sales Charge (load) (as apercentage of the net asset value at time ofpurchase or redemption, whichever is lower) N/A

ANNUAL PORTFOLIO OPERATING EXPENSES(expenses that you pay each year as a percentage ofthe value of your investment)

Management Fees 0.64%

Other Expenses 0.03%

Total Annual Portfolio Operating Expenses 0.67%

EXAMPLE This example is intended to help youcompare the cost of investing in the Portfolio with thecost of investing in other mutual funds. The Portfolio isan investment option for variable contracts, and theexample does not include charges imposed by variablecontracts. If variable contract charges were imposed,your expenses would be higher than those shown. Theexample assumes that you invest $10,000 in thePortfolio for the time periods indicated and thenredeem all of your shares at the end of those periods.The example also assumes that your investment has a5% return each year, and that the Portfolio’s operatingexpenses remain the same. Although your actual costmay be higher or lower, based on the foregoingassumptions, your cost would be:

1 Year 3 Years 5 Years 10 Years

Thrivent Mid CapStock Portfolio $68 $214 $373 $835

Portfolio TurnoverThe Portfolio pays transaction costs, such ascommissions, when it buys and sells securities (or “turns

over” its portfolio). A higher portfolio turnover rate mayindicate higher transaction costs and may result inhigher taxes when Portfolio shares are held in a taxableaccount. These costs, which are not reflected in annualfund operating expenses or in the example, affect thePortfolio’s performance. During the most recent fiscalyear, the Portfolio’s portfolio turnover rate was 30% ofthe average value of its portfolio.

Principal StrategiesUnder normal circumstances, the Portfolio invests atleast 80% of its net assets (plus the amount of anyborrowing for investment purposes) in equity securitiesof mid-sized companies. The Adviser focuses mainly onthe equity securities of mid-sized U.S. companies whichhave market capitalizations equivalent to thoseincluded in widely known indices such as the S&PMidCap 400 Index, MSCI USA Mid Cap Index, or themid-sized company market capitalization classificationspublished by Lipper, Inc. These companies typicallyhave a market capitalization of approximately $2 billionto $25 billion. Should the Adviser determine that thePortfolio would benefit from reducing the percentage ofits assets invested in mid cap equity securities from 80%to a lesser amount, we will notify you at least 60 daysprior to the change.

The Portfolio seeks to achieve its investment objectiveby investing in common stocks. The Adviser usesfundamental, quantitative, and technical investmentresearch techniques to determine what securities to buyand sell. Fundamental techniques assess a security’svalue based on an issuer’s financial profile,management, and business prospects while quantitativeand technical techniques involve a more data-orientedanalysis of financial information, market trends andprice movements. The Adviser generally looks formid-sized companies that, in its opinion:

• have prospects for growth in their sales andearnings;

• are in an industry with a good economic outlook;• have high-quality management; and/or• have a strong financial position.

The Portfolio may also pursue its investment strategy byinvesting in other mutual funds, including fundsmanaged by the Adviser or an affiliate.

The Adviser may sell securities for a variety of reasons,such as to secure gains, limit losses, or reposition assetsto more promising opportunities.

1 The Adviser has contractually agreed, for as long as the current feestructure is in place and through at least April 30, 2019, to waive anamount equal to any investment advisory fees indirectly incurredby the Portfolio as a result of its investment in any other mutualfund for which the Adviser or an affiliate serves as investmentadviser, other than Thrivent Cash Management Trust. Thiscontractual provision may be terminated upon the mutualagreement between the Independent Directors of the Portfolio andthe Adviser.

EXAMPLE This example is intended to help youcompare the cost of investing in the Portfolio with thecost of investing in other mutual funds. The Portfolio isan investment option for variable contracts, and theexample does not include charges imposed by variablecontracts. If variable contract charges were imposed,your expenses would be higher than those shown. Theexample assumes that you invest $10,000 in thePortfolio for the time periods indicated and thenredeem all of your shares at the end of those periods. Inaddition, the example for the 1 Year period reflects the

effect of the contractual fee waiver and/or expensereimbursement. The example also assumes that yourinvestment has a 5% return each year, and that thePortfolio’s operating expenses remain the same.Although your actual cost may be higher or lower, basedon the foregoing assumptions, your cost would be:

1 Year 3 Years 5 Years 10 Years

Thrivent ModerateAllocation Portfolio $65 $242 $433 $986

Portfolio TurnoverThe Portfolio pays transaction costs, such ascommissions, when it buys and sells securities (or “turnsover” its portfolio). A higher portfolio turnover rate mayindicate higher transaction costs and may result inhigher taxes when Portfolio shares are held in a taxableaccount. These costs, which are not reflected in annualfund operating expenses or in the example, affect thePortfolio’s performance. During the most recent fiscalyear, the Portfolio’s portfolio turnover rate was 155% ofthe average value of its portfolio.

Principal StrategiesThe Portfolio pursues its objective by investing in acombination of other funds managed by the Adviser oran affiliate and directly held financial instruments. ThePortfolio uses a prescribed asset allocation strategyinvolving a two-step process that is designed to achievea desired risk tolerance generally aligned with its peergroup as published by Lipper, Inc. The first step is theconstruction of a model for the allocation of thePortfolio’s assets across broad asset categories (namely,equity securities and debt securities). The second stepinvolves the determination of sub-classes within thebroad asset categories and target weightings (i.e., whatthe Adviser determines is the strategic allocation) forthese sub-classes. Sub-classes may be based on marketcapitalization, investment style (such as growth orvalue), or economic sector for equity securities.Sub-classes for debt securities may be based on maturity,duration, security type or credit rating (high yield—commonly known as “junk bonds”—or investmentgrade) and may include leveraged loans, which aresenior secured loans that are made by banks or otherlending institutions to companies that are rated belowinvestment grade.

The use of target weightings for various sub-classeswithin broad asset categories is intended as a multi-styleapproach to reduce the risk of investing in securitieshaving common characteristics. The Portfolio may buyand sell futures contracts to either hedge its exposure orobtain exposure to certain investments. The Portfolio

may also enter into credit default swap agreements onsecurity indexes. The Portfolio may enter intostandardized derivatives contracts traded on domestic orforeign securities exchanges, boards of trade, or similarentities, and non-standardized derivatives contractstraded in the over-the-counter market.

Under normal circumstances, the Portfolio invests inthe following broad asset classes within the rangesgiven:

The Portfolio’s actual holdings in each broad assetcategory may be outside the applicable allocation rangefrom time to time due to differing investmentperformance among asset categories. The Adviser willrebalance the Portfolio at least annually so that itsholdings are within the ranges for the broad assetcategories.

The Portfolio also pursues its investment strategy byinvesting in other mutual funds, including fundsmanaged by the Adviser or an affiliate. The names ofthe funds managed by the Adviser or an affiliate whichare currently available for investment by the Portfolioare shown in the list below.

Principal RisksThe Portfolio is subject to the following principalinvestment risks. Shares of the Portfolio will rise and fallin value and there is a risk that you could lose moneyby investing in the Portfolio. The Portfolio cannot becertain that it will achieve its investment objective.

Allocation Risk. The Portfolio’s investmentperformance depends upon how its assets are allocatedacross broad asset categories and applicable sub-classeswithin such categories. Some broad asset categories andsub-classes may perform below expectations or thesecurities markets generally over short and extendedperiods. Underperformance in the equity markets ordebt markets would have a material adverse effect onthe Portfolio’s total return given its significantallocation to both equity securities and debt securities.Therefore, a principal risk of investing in the Portfolio isthat the allocation strategies used and the allocationdecisions made will not produce the desired results.

Credit Risk. Credit risk is the risk that an issuer of adebt security to which the Portfolio is exposed may nolonger be able or willing to pay its debt. As a result ofsuch an event, the debt security may decline in priceand affect the value of the Portfolio.

Derivatives Risk. The use of derivatives (such asfutures and credit default swaps) involves additionalrisks and transaction costs which could leave thePortfolio in a worse position than if it had not usedthese instruments. The use of derivatives can lead tolosses because of adverse movements in the price orvalue of the underlying asset, index or rate, which maybe magnified by certain features of the contract.Changes in the value of the derivative may not correlateas intended with the underlying asset, rate or index, andthe Portfolio could lose much more than the originalamount invested. Derivatives can be highly volatile,illiquid and difficult to value. Certain derivatives mayalso be subject to counterparty risk, which is that theother party in the transaction will not fulfill itscontractual obligations due to its financial condition,market events, or other reasons.

Foreign Securities Risk. Foreign securities aregenerally more volatile than their domesticcounterparts, in part because of higher political andeconomic risks, lack of reliable information andfluctuations in currency exchange rates. Foreignsecurities may also be more difficult to resell thancomparable U.S. securities because the markets forforeign securities are often less liquid. Even when aforeign security increases in price in its local currency,

TSF-77

Page 122: Single Premium Immediate Variable Annuity · PDF fileSingle Premium Immediate Variable Annuity Issued between 7/26/1999 and 4/29/2016. Prospectuses April 30, 2017 Thrivent Variable

the appreciation may be diluted by adverse changes inexchange rates when the security’s value is converted toU.S. dollars. Foreign withholding taxes also may applyand errors and delays may occur in the settlementprocess for foreign securities. All of these risks may beheightened for securities of issuers located in, or withsignificant operations in, emerging market countries.

Growth Investing Risk. Growth style investingincludes the risk of investing in securities whose priceshistorically have been more volatile than othersecurities, especially over the short term. Growth stockprices reflect projections of future earnings or revenuesand, if a company’s earnings or revenues fall short ofexpectations, its stock price may fall dramatically.

High Yield Risk. High yield securities – commonlyknown as “junk bonds” – to which the Portfolio isexposed are considered predominantly speculative withrespect to the issuer’s continuing ability to makeprincipal and interest payments. If the issuer of thesecurity is in default with respect to interest or principalpayments, the value of the Portfolio may be negativelyaffected.

Investment Adviser Risk. The Portfolio is activelymanaged and the success of its investment strategydepends significantly on the skills of the Adviser inassessing the potential of the investments in which thePortfolio invests. This assessment of investments mayprove incorrect, resulting in losses or poor performance,even in rising markets.

Interest Rate Risk. Interest rate risk is the risk thatprices of debt securities decline in value when interestrates rise for debt securities that pay a fixed rate ofinterest. Debt securities with longer durations (ameasure of price sensitivity of a bond or bond fund tochanges in interest rates) or maturities (i.e., the amountof time until a bond’s issuer must pay its principal orface value) tend to be more sensitive to changes ininterest rates than debt securities with shorter durationsor maturities. Changes by the Federal Reserve tomonetary policies could affect interest rates and thevalue of some securities.

Issuer Risk. Issuer risk is the possibility that factorsspecific to a company to which the Portfolio is exposedwill affect the market prices of the company’s securitiesand therefore the value of the Portfolio. Common stockof a company is subordinate to other securities issued bythe company. If a company becomes insolvent, interestsof investors owning common stock will be subordinatedto the interests of other investors in, and generalcreditors of, the company.

Large Cap Risk. Large-sized companies may be unableto respond quickly to new competitive challenges suchas changes in technology. They may also not be able toattain the high growth rate of successful smaller

companies, especially during extended periods ofeconomic expansion.

Leveraged Loan Risk. Leveraged loans (also known asbank loans) are subject to the risks typically associatedwith debt securities. In addition, leveraged loans, whichtypically hold a senior position in the capital structureof a borrower, are subject to the risk that a court couldsubordinate such loans to presently existing or futureindebtedness or take other action detrimental to theholders of leveraged loans. Leveraged loans are alsosubject to the risk that the value of the collateral, if any,securing a loan may decline, be insufficient to meet theobligations of the borrower, or be difficult to liquidate.Some leveraged loans are not as easily purchased or soldas publicly-traded securities and others are illiquid,which may make it more difficult for the Portfolio tovalue them or dispose of them at an acceptable price.Below investment-grade leveraged loans are typicallymore credit sensitive. In the event of fraud ormisrepresentation, the Portfolio may not be protectedunder federal securities laws with respect to leveragedloans that may not be in the form of “securities.” Thesettlement period for some leveraged loans may be morethan seven days.

Liquidity Risk. Liquidity is the ability to sell a securityrelatively quickly for a price that most closely reflectsthe actual value of the security. Dealer inventories ofbonds are at or near historic lows in relation to marketsize, which has the potential to decrease liquidity andincrease price volatility in the fixed income markets,particularly during periods of economic or market stress.As a result of this decreased liquidity, the Adviser mayhave to accept a lower price to sell a security, sell othersecurities to raise cash, or give up an investmentopportunity, any of which could have a negative effecton performance.

Market Risk. Over time, securities markets generallytend to move in cycles with periods when securityprices rise and periods when security prices decline. Thevalue of the Portfolio’s investments may move withthese cycles and, in some instances, increase or decreasemore than the applicable market(s) as measured by thePortfolio’s benchmark index(es). The securities marketsmay also decline because of factors that affect aparticular industry.

Non-Diversified Risk. The Portfolio is not“diversified” within the meaning of the 1940 Act. Thatmeans the Portfolio may invest a greater percentage ofits assets in the securities of any single issuer comparedto other funds. A non-diversified portfolio is generallymore susceptible than a diversified portfolio to the riskthat events or developments affecting a particular issueror industry will significantly affect the Portfolio’sperformance.

Portfolio Turnover Rate Risk. The Portfolio mayengage in active and frequent trading of portfoliosecurities in implementing its principal investmentstrategies. A high rate of portfolio turnover (100% ormore) involves correspondingly greater expenses whichare borne by the Portfolio and its shareholders and mayalso result in short-term capital gains taxable toshareholders.

Small and Mid Cap Risk. Small- and medium-sizedcompanies often have greater price volatility, lowertrading volumes, and less liquidity than larger, moreestablished companies. These companies tend to havesmaller revenues, narrower product lines, lessmanagement depth and experience, smaller shares oftheir product or service markets, fewer financialresources, and less competitive strength than largercompanies.

Value Investing Risk. Value style investing includesthe risk that stocks of undervalued companies may notrise as quickly as anticipated if the market doesn’trecognize their intrinsic value or if value stocks are outof favor.

Volatility Risk. Volatility risk is the risk that certaintypes of securities shift in and out of favor dependingon market and economic conditions as well as investorsentiment. From time to time, equity investments mayfall out of favor as compared to investments in debtsecurities, and vice versa. Small, less seasonedcompanies and medium-size companies often havegreater price volatility, lower trading volume, and lessliquidity than larger, more-established companies.

1 The Adviser has contractually agreed, for as long as the current feestructure is in place and through at least April 30, 2019, to waive anamount equal to any investment advisory fees indirectly incurredby the Portfolio as a result of its investment in any other mutualfund for which the Adviser or an affiliate serves as investmentadviser, other than Thrivent Cash Management Trust.

EXAMPLE This example is intended to help youcompare the cost of investing in the Portfolio with thecost of investing in other mutual funds. The Portfolio isan investment option for variable contracts, and theexample does not include charges imposed by variablecontracts. If variable contract charges were imposed,your expenses would be higher than those shown. Theexample assumes that you invest $10,000 in thePortfolio for the time periods indicated and thenredeem all of your shares at the end of those periods. Inaddition, the example for the 1 Year period reflects theeffect of the contractual fee waiver and/or expense

Thrivent ModeratelyAggressive AllocationPortfolio $73 $277 $498 $1,134

Portfolio TurnoverThe Portfolio pays transaction costs, such ascommissions, when it buys and sells securities (or “turnsover” its portfolio). A higher portfolio turnover rate mayindicate higher transaction costs and may result inhigher taxes when Portfolio shares are held in a taxableaccount. These costs, which are not reflected in annualfund operating expenses or in the example, affect thePortfolio’s performance. During the most recent fiscalyear, the Portfolio’s portfolio turnover rate was 104% ofthe average value of its portfolio.

Principal StrategiesThe Portfolio pursues its objective by investing in acombination of other funds managed by the Adviser oran affiliate and directly held financial instruments. ThePortfolio uses a prescribed asset allocation strategyinvolving a two-step process that is designed to achievea desired risk tolerance generally aligned with its peergroup as published by Lipper, Inc. The first step is theconstruction of a model for the allocation of thePortfolio’s assets across broad asset categories (namely,equity securities and debt securities). The second stepinvolves the determination of sub-classes within thebroad asset categories and target weightings (i.e., whatthe Adviser determines is the strategic allocation) forthese sub-classes. Sub-classes may be based on marketcapitalization, investment style (such as growth orvalue), or economic sector for equity securities.Sub-classes for debt securities may be based on maturity,duration, security type or credit rating (high yield—commonly known as “junk bonds”—or investmentgrade) and may include leveraged loans, which aresenior secured loans that are made by banks or otherlending institutions to companies that are rated belowinvestment grade.

The use of target weightings for various sub-classeswithin broad asset categories is intended as a multi-styleapproach to reduce the risk of investing in securitieshaving common characteristics. The Portfolio may buyand sell futures contracts to either hedge its exposure orobtain exposure to certain investments. The Portfolio

may also enter into credit default swap agreements onsecurity indexes. The Portfolio may enter intostandardized derivatives contracts traded on domestic orforeign securities exchanges, boards of trade, or similarentities, and non-standardized derivatives contractstraded in the over-the-counter market.

Under normal circumstances, the Portfolio invests inthe following broad asset classes within the rangesgiven:

The Portfolio’s actual holdings in each broad assetcategory may be outside the applicable allocation rangefrom time to time due to differing investmentperformance among asset categories. The Adviser willrebalance the Portfolio at least annually so that itsholdings are within the ranges for the broad assetcategories.

The Portfolio also pursues its investment strategy byinvesting in other mutual funds, including fundsmanaged by the Adviser or an affiliate. The names ofthe funds managed by the Adviser or an affiliate whichare currently available for investment by the Portfolioare shown in the list below.

Principal RisksThe Portfolio is subject to the following principalinvestment risks. Shares of the Portfolio will rise and fallin value and there is a risk that you could lose moneyby investing in the Portfolio. The Portfolio cannot becertain that it will achieve its investment objective.

Allocation Risk. The Portfolio’s investmentperformance depends upon how its assets are allocatedacross broad asset categories and applicable sub-classeswithin such categories. Some broad asset categories andsub-classes may perform below expectations or thesecurities markets generally over short and extendedperiods. Underperformance in the equity markets wouldhave a material adverse effect on the Portfolio’s totalreturn given its significant allocation to equitysecurities. Therefore, a principal risk of investing in thePortfolio is that the allocation strategies used and theallocation decisions made will not produce the desiredresults.

Credit Risk. Credit risk is the risk that an issuer of adebt security to which the Portfolio is exposed may nolonger be able or willing to pay its debt. As a result ofsuch an event, the debt security may decline in priceand affect the value of the Portfolio.

Derivatives Risk. The use of derivatives (such asfutures and credit default swaps) involves additionalrisks and transaction costs which could leave thePortfolio in a worse position than if it had not usedthese instruments. The use of derivatives can lead tolosses because of adverse movements in the price orvalue of the underlying asset, index or rate, which maybe magnified by certain features of the contract.Changes in the value of the derivative may not correlateas intended with the underlying asset, rate or index, andthe Portfolio could lose much more than the originalamount invested. Derivatives can be highly volatile,illiquid and difficult to value. Certain derivatives mayalso be subject to counterparty risk, which is that theother party in the transaction will not fulfill itscontractual obligations due to its financial condition,market events, or other reasons.

Foreign Securities Risk. Foreign securities aregenerally more volatile than their domesticcounterparts, in part because of higher political andeconomic risks, lack of reliable information andfluctuations in currency exchange rates. Foreignsecurities may also be more difficult to resell thancomparable U.S. securities because the markets forforeign securities are often less liquid. Even when aforeign security increases in price in its local currency,

the appreciation may be diluted by adverse changes inexchange rates when the security’s value is converted toU.S. dollars. Foreign withholding taxes also may applyand errors and delays may occur in the settlementprocess for foreign securities. All of these risks may beheightened for securities of issuers located in, or withsignificant operations in, emerging market countries.

Growth Investing Risk. Growth style investingincludes the risk of investing in securities whose priceshistorically have been more volatile than othersecurities, especially over the short term. Growth stockprices reflect projections of future earnings or revenuesand, if a company’s earnings or revenues fall short ofexpectations, its stock price may fall dramatically.

High Yield Risk. High yield securities – commonlyknown as “junk bonds” – to which the Portfolio isexposed are considered predominantly speculative withrespect to the issuer’s continuing ability to makeprincipal and interest payments. If the issuer of thesecurity is in default with respect to interest or principalpayments, the value of the Portfolio may be negativelyaffected.

Interest Rate Risk. Interest rate risk is the risk thatprices of debt securities decline in value when interestrates rise for debt securities that pay a fixed rate ofinterest. Debt securities with longer durations (ameasure of price sensitivity of a bond or bond fund tochanges in interest rates) or maturities (i.e., the amountof time until a bond’s issuer must pay its principal orface value) tend to be more sensitive to changes ininterest rates than debt securities with shorter durationsor maturities. Changes by the Federal Reserve tomonetary policies could affect interest rates and thevalue of some securities.

Investment Adviser Risk. The Portfolio is activelymanaged and the success of its investment strategydepends significantly on the skills of the Adviser inassessing the potential of the investments in which thePortfolio invests. This assessment of investments mayprove incorrect, resulting in losses or poor performance,even in rising markets.

Issuer Risk. Issuer risk is the possibility that factorsspecific to a company to which the Portfolio is exposedwill affect the market prices of the company’s securitiesand therefore the value of the Portfolio. Common stockof a company is subordinate to other securities issued bythe company. If a company becomes insolvent, interestsof investors owning common stock will be subordinatedto the interests of other investors in, and generalcreditors of, the company.

Large Cap Risk. Large-sized companies may be unableto respond quickly to new competitive challenges suchas changes in technology. They may also not be able toattain the high growth rate of successful smaller

companies, especially during extended periods ofeconomic expansion.

Leveraged Loan Risk. Leveraged loans (also known asbank loans) are subject to the risks typically associatedwith debt securities. In addition, leveraged loans, whichtypically hold a senior position in the capital structureof a borrower, are subject to the risk that a court couldsubordinate such loans to presently existing or futureindebtedness or take other action detrimental to theholders of leveraged loans. Leveraged loans are alsosubject to the risk that the value of the collateral, if any,securing a loan may decline, be insufficient to meet theobligations of the borrower, or be difficult to liquidate.Some leveraged loans are not as easily purchased or soldas publicly-traded securities and others are illiquid,which may make it more difficult for the Portfolio tovalue them or dispose of them at an acceptable price.Below investment-grade leveraged loans are typicallymore credit sensitive. In the event of fraud ormisrepresentation, the Portfolio may not be protectedunder federal securities laws with respect to leveragedloans that may not be in the form of “securities.” Thesettlement period for some leveraged loans may be morethan seven days.

Liquidity Risk. Liquidity is the ability to sell a securityrelatively quickly for a price that most closely reflectsthe actual value of the security. Dealer inventories ofbonds are at or near historic lows in relation to marketsize, which has the potential to decrease liquidity andincrease price volatility in the fixed income markets,particularly during periods of economic or market stress.As a result of this decreased liquidity, the Adviser mayhave to accept a lower price to sell a security, sell othersecurities to raise cash, or give up an investmentopportunity, any of which could have a negative effecton performance.

Market Risk. Over time, securities markets generallytend to move in cycles with periods when securityprices rise and periods when security prices decline. Thevalue of the Portfolio’s investments may move withthese cycles and, in some instances, increase or decreasemore than the applicable market(s) as measured by thePortfolio’s benchmark index(es). The securities marketsmay also decline because of factors that affect aparticular industry.

Non-Diversified Risk. The Portfolio is not“diversified” within the meaning of the 1940 Act. Thatmeans the Portfolio may invest a greater percentage ofits assets in the securities of any single issuer comparedto other funds. A non-diversified portfolio is generallymore susceptible than a diversified portfolio to the riskthat events or developments affecting a particular issueror industry will significantly affect the Portfolio’sperformance.

Other Funds Risk. The performance of the Portfolio isdependent, in part, upon the performance of otherfunds manged by the Adviser or an affiliate (“OtherFunds”) in which the Portfolio invests. As a result, thePortfolio is subject to the same risks as those faced bythe Other Funds.

Portfolio Turnover Rate Risk. The Portfolio mayengage in active and frequent trading of portfoliosecurities in implementing its principal investmentstrategies. A high rate of portfolio turnover (100% ormore) involves correspondingly greater expenses whichare borne by the Portfolio and its shareholders and mayalso result in short-term capital gains taxable toshareholders.

Small and Mid Cap Risk. Small- and medium-sizedcompanies often have greater price volatility, lowertrading volumes, and less liquidity than larger, moreestablished companies. These companies tend to havesmaller revenues, narrower product lines, lessmanagement depth and experience, smaller shares oftheir product or service markets, fewer financialresources, and less competitive strength than largercompanies.

Value Investing Risk. Value style investing includesthe risk that stocks of undervalued companies may notrise as quickly as anticipated if the market doesn’trecognize their intrinsic value or if value stocks are outof favor.

EXAMPLE This example is intended to help youcompare the cost of investing in the Portfolio with thecost of investing in other mutual funds. The Portfolio isan investment option for variable contracts, and theexample does not include charges imposed by variablecontracts. If variable contract charges were imposed,your expenses would be higher than those shown. Theexample assumes that you invest $10,000 in thePortfolio for the time periods indicated and thenredeem all of your shares at the end of those periods. Inaddition, the example for the 1 Year period reflects the

effect of the contractual fee waiver and/or expensereimbursement. The example also assumes that yourinvestment has a 5% return each year, and that thePortfolio’s operating expenses remain the same.Although your actual cost may be higher or lower, basedon the foregoing assumptions, your cost would be:

Portfolio TurnoverThe Portfolio pays transaction costs, such ascommissions, when it buys and sells securities (or “turnsover” its portfolio). A higher portfolio turnover rate mayindicate higher transaction costs and may result inhigher taxes when Portfolio shares are held in a taxableaccount. These costs, which are not reflected in annualfund operating expenses or in the example, affect thePortfolio’s performance. During the most recent fiscalyear, the Portfolio’s portfolio turnover rate was 207% ofthe average value of its portfolio.

Principal StrategiesThe Portfolio pursues its objective by investing in acombination of other funds managed by the Adviser oran affiliate and directly held financial instruments. ThePortfolio uses a prescribed asset allocation strategyinvolving a two-step process that is designed to achievea desired risk tolerance generally aligned with its peergroup as published by Lipper, Inc. The first step is theconstruction of a model for the allocation of thePortfolio’s assets across broad asset categories (namely,debt securities and equity securities). The second stepinvolves the determination of sub-classes within thebroad asset categories and target weightings (i.e., whatthe Adviser determines is the strategic allocation) forthese sub-classes. Sub-classes may be based on maturity,duration, security type or credit rating (high yield—commonly known as “junk bonds”—or investmentgrade) for debt securities. Sub-classes for equitysecurities may be based on market capitalization,investment style (such as growth or value), or economicsector and may include leveraged loans, which aresenior secured loans that are made by banks or otherlending institutions to companies that are rated belowinvestment grade.

The use of target weightings for various sub-classeswithin broad asset categories is intended as a multi-styleapproach to reduce the risk of investing in securitieshaving common characteristics. The Portfolio may buyand sell futures contracts to either hedge its exposure orobtain exposure to certain investments. The Portfolio

may also enter into credit default swap agreements onsecurity indexes. The Portfolio may enter intostandardized derivatives contracts traded on domestic orforeign securities exchanges, boards of trade, or similarentities, and non-standardized derivatives contractstraded in the over-the-counter market.

Under normal circumstances, the Portfolio invests inthe following broad asset classes within the rangesgiven:

The Portfolio’s actual holdings in each broad assetcategory may be outside the applicable allocation rangefrom time to time due to differing investmentperformance among asset categories. The Adviser willrebalance the Portfolio at least annually so that itsholdings are within the ranges for the broad assetcategories.

The Portfolio also pursues its investment strategy byinvesting in other mutual funds, including fundsmanaged by the Adviser or an affiliate. The names ofthe funds managed by the Adviser or an affiliate whichare currently available for investment by the Portfolioare shown in the list below. The list is provided forinformation purposes only.

Principal RisksThe Portfolio is subject to the following principalinvestment risks. Shares of the Portfolio will rise and fallin value and there is a risk that you could lose moneyby investing in the Portfolio. The Portfolio cannot becertain that it will achieve its investment objective.

Allocation Risk. The Portfolio’s investmentperformance depends upon how its assets are allocatedacross broad asset categories and applicable sub-classeswithin such categories. Some broad asset categories andsub-classes may perform below expectations or thesecurities markets generally over short and extendedperiods. Underperformance in the equity markets ordebt markets would have a material adverse effect onthe Portfolio’s total returns given its significantallocation to equity securities and debt securities.Therefore, a principal risk of investing in the Portfolio isthat the allocation strategies used and the allocationdecisions made will not produce the desired results.

Credit Risk. Credit risk is the risk that an issuer of adebt security to which the Portfolio is exposed may nolonger be able or willing to pay its debt. As a result ofsuch an event, the debt security may decline in priceand affect the value of the Portfolio.

Derivatives Risk. The use of derivatives (such asfutures and credit default swaps) involves additionalrisks and transaction costs which could leave thePortfolio in a worse position than if it had not usedthese instruments. The use of derivatives can lead tolosses because of adverse movements in the price orvalue of the underlying asset, index or rate, which maybe magnified by certain features of the contract.Changes in the value of the derivative may not correlateas intended with the underlying asset, rate or index, andthe Portfolio could lose much more than the originalamount invested. Derivatives can be highly volatile,illiquid and difficult to value. Certain derivatives mayalso be subject to counterparty risk, which is that theother party in the transaction will not fulfill itscontractual obligations due to its financial condition,market events, or other reasons.

Foreign Securities Risk. Foreign securities aregenerally more volatile than their domesticcounterparts, in part because of higher political andeconomic risks, lack of reliable information andfluctuations in currency exchange rates. Foreignsecurities may also be more difficult to resell thancomparable U.S. securities because the markets forforeign securities are often less liquid. Even when aforeign security increases in price in its local currency,the appreciation may be diluted by adverse changes in

Page 134: Single Premium Immediate Variable Annuity · PDF fileSingle Premium Immediate Variable Annuity Issued between 7/26/1999 and 4/29/2016. Prospectuses April 30, 2017 Thrivent Variable

exchange rates when the security’s value is converted toU.S. dollars. Foreign withholding taxes also may applyand errors and delays may occur in the settlementprocess for foreign securities. All of these risks may beheightened for securities of issuers located in, or withsignificant operations in, emerging market countries.

Growth Investing Risk. Growth style investingincludes the risk of investing in securities whose priceshistorically have been more volatile than othersecurities, especially over the short term. Growth stockprices reflect projections of future earnings or revenuesand, if a company’s earnings or revenues fall short ofexpectations, its stock price may fall dramatically.

High Yield Risk. High yield securities – commonlyknown as “junk bonds” – to which the Portfolio isexposed are considered predominantly speculative withrespect to the issuer’s continuing ability to makeprincipal and interest payments. If the issuer of thesecurity is in default with respect to interest or principalpayments, the value of the Portfolio may be negativelyaffected.

Interest Rate Risk. Interest rate risk is the risk thatprices of debt securities decline in value when interestrates rise for debt securities that pay a fixed rate ofinterest. Debt securities with longer durations (ameasure of price sensitivity of a bond or bond fund tochanges in interest rates) or maturities (i.e., the amountof time until a bond’s issuer must pay its principal orface value) tend to be more sensitive to changes ininterest rates than debt securities with shorter durationsor maturities. Changes by the Federal Reserve tomonetary policies could affect interest rates and thevalue of some securities.

Investment Adviser Risk. The Portfolio is activelymanaged and the success of its investment strategydepends significantly on the skills of the Adviser inassessing the potential of the investments in which thePortfolio invests. This assessment of investments mayprove incorrect, resulting in losses or poor performance,even in rising markets.

Issuer Risk. Issuer risk is the possibility that factorsspecific to a company to which the Portfolio is exposedwill affect the market prices of the company’s securitiesand therefore the value of the Portfolio. Common stockof a company is subordinate to other securities issued bythe company. If a company becomes insolvent, interestsof investors owning common stock will be subordinatedto the interests of other investors in, and generalcreditors of, the company.

Large Cap Risk. Large-sized companies may be unableto respond quickly to new competitive challenges suchas changes in technology. They may also not be able toattain the high growth rate of successful smallercompanies, especially during extended periods ofeconomic expansion.

Leveraged Loan Risk. Leveraged loans (also known asbank loans) are subject to the risks typically associatedwith debt securities. In addition, leveraged loans, whichtypically hold a senior position in the capital structureof a borrower, are subject to the risk that a court couldsubordinate such loans to presently existing or futureindebtedness or take other action detrimental to theholders of leveraged loans. Leveraged loans are alsosubject to the risk that the value of the collateral, if any,securing a loan may decline, be insufficient to meet theobligations of the borrower, or be difficult to liquidate.Some leveraged loans are not as easily purchased or soldas publicly-traded securities and others are illiquid,which may make it more difficult for the Portfolio tovalue them or dispose of them at an acceptable price.Below investment-grade leveraged loans are typicallymore credit sensitive. In the event of fraud ormisrepresentation, the Portfolio may not be protectedunder federal securities laws with respect to leveragedloans that may not be in the form of “securities.” Thesettlement period for some leveraged loans may be morethan seven days.

Liquidity Risk. Liquidity is the ability to sell a securityrelatively quickly for a price that most closely reflectsthe actual value of the security. Dealer inventories ofbonds are at or near historic lows in relation to marketsize, which has the potential to decrease liquidity andincrease price volatility in the fixed income markets,particularly during periods of economic or market stress.As a result of this decreased liquidity, the Adviser mayhave to accept a lower price to sell a security, sell othersecurities to raise cash, or give up an investmentopportunity, any of which could have a negative effecton performance.

Market Risk. Over time, securities markets generallytend to move in cycles with periods when securityprices rise and periods when security prices decline. Thevalue of the Portfolio’s investments may move withthese cycles and, in some instances, increase or decreasemore than the applicable market(s) as measured by thePortfolio’s benchmark index(es). The securities marketsmay also decline because of factors that affect aparticular industry.

Non-Diversified Risk. The Portfolio is not“diversified” within the meaning of the 1940 Act. Thatmeans the Portfolio may invest a greater percentage ofits assets in the securities of any single issuer comparedto other funds. A non-diversified portfolio is generallymore susceptible than a diversified portfolio to the riskthat events or developments affecting a particular issueror industry will significantly affect the Portfolio’sperformance.

Other Funds Risk. The performance of the Portfolio isdependent, in part, upon the performance of otherfunds manged by the Adviser or an affiliate (“OtherFunds”) in which the Portfolio invests. As a result, the

Page 135: Single Premium Immediate Variable Annuity · PDF fileSingle Premium Immediate Variable Annuity Issued between 7/26/1999 and 4/29/2016. Prospectuses April 30, 2017 Thrivent Variable

Portfolio is subject to the same risks as those faced bythe Other Funds.

Portfolio Turnover Rate Risk. The Portfolio mayengage in active and frequent trading of portfoliosecurities in implementing its principal investmentstrategies. A high rate of portfolio turnover (100% ormore) involves correspondingly greater expenses whichare borne by the Portfolio and its shareholders and mayalso result in short-term capital gains taxable toshareholders.

Small and Mid Cap Risk. Small- and medium-sizedcompanies often have greater price volatility, lowertrading volumes, and less liquidity than larger, moreestablished companies. These companies tend to havesmaller revenues, narrower product lines, lessmanagement depth and experience, smaller shares oftheir product or service markets, fewer financialresources, and less competitive strength than largercompanies.

Value Investing Risk. Value style investing includesthe risk that stocks of undervalued companies may notrise as quickly as anticipated if the market doesn’trecognize their intrinsic value or if value stocks are outof favor.

Volatility Risk. Volatility risk is the risk that certaintypes of securities shift in and out of favor dependingon market and economic conditions as well as investorsentiment. From time to time, debt investments mayfall out of favor as compared to investments in equitysecurities, and vice versa. Small, less seasonedcompanies and medium-size companies often havegreater price volatility, lower trading volume, and lessliquidity than larger, more-established companies.

Principal StrategiesThe Portfolio tries to produce current income whilemaintaining liquidity by investing at least 99.5% of itstotal assets in government securities, cash andrepurchase agreements collateralized fully bygovernment securities or cash. Government securitiesare any securities issued or guaranteed as to principal orinterest by the United States, or by a person controlledor supervised by and acting as an instrumentality of thegovernment of the United States pursuant to authoritygranted by the Congress of the United States; or anycertificate of deposit for any of the foregoing.

The Adviser manages the Portfolio subject to strict rulesestablished by the Securities and Exchange Commissionthat are designed so that the Portfolio may maintain astable $1.00 share price. Those rules generally requirethe Portfolio, among other things, to invest only inhigh quality securities that are denominated in U.S.dollars and have short remaining maturities. Inaddition, the rules require the Portfolio to maintain adollar-weighted average maturity (WAM) of not morethan 60 days and a dollar-weighted average life (WAL) ofnot more than 120 days. When calculating its WAM, thePortfolio may shorten its maturity by using the interestrate resets of certain adjustable rate securities. Generally,the Portfolio may not take into account these resetswhen calculating its WAL.

The Adviser typically uses U.S. Treasury securities,short-term discount notes issued by government-relatedorganizations and government securities payable withinseven-days or less to provide liquidity for reasonablyforeseeable shareholder redemptions and to complywith regulatory requirements. The Adviser invests inother securities by selecting from the available supply ofshort-term government securities based on its interestrate outlook and analysis of quantitative and technicalfactors. Although the Portfolio frequently holdssecurities until maturity, the Adviser may sell securitiesto increase liquidity. The Adviser will select securities forsuch sales based on how close the sale price would be totheir amortized costs.

Principal RisksYou could lose money by investing in the Portfolio.Although the Portfolio seeks to preserve the value ofyour investment at $1.00 per share, it cannot guaranteeit will do so. An investment in the Portfolio is notinsured or guaranteed by the Federal Deposit InsuranceCorporation or any other government agency. ThePortfolio’s sponsor has no legal obligation to providefinancial support to the Portfolio, and you should notexpect that the sponsor will provide financial support to

the Portfolio at any time. In addition, the Portfolio issubject to the following principal investment risks.

Credit Risk. Credit risk is the risk that an issuer of adebt security to which the Portfolio is exposed may nolonger be able or willing to pay its debt. As a result ofsuch an event, the debt security may decline in priceand affect the value of the Portfolio. Credit risk isexpected to be low for the Portfolio because of itsinvestments in government securities.

Government Securities Risk. The Portfolio invests insecurities issued or guaranteed by the U.S. governmentor its agencies and instrumentalities (such as FederalHome Loan Bank Ginnie Mae, Fannie Mae or FreddieMac securities). Securities issued or guaranteed byFederal Home Loan Bank Ginnie Mae, Fannie Mae orFreddie Mac are not issued directly by the U.S.government. Ginnie Mae is a wholly owned U.S.corporation that is authorized to guarantee, with thefull faith and credit of the U.S. government, the timelypayment of principal and interest of its securities. Bycontrast, securities issued or guaranteed by U.S.government-related organizations such as Federal HomeLoan Bank Fannie Mae and Freddie Mac are not backedby the full faith and credit of the U.S. government. Noassurance can be given that the U.S. government wouldprovide financial support to its agencies andinstrumentalities if not required to do so by law. Inaddition, the value of U.S. government securities may beaffected by changes in the credit rating of the U.S.government.

Interest Rate Risk. A weak economy, strong equitymarkets, or changes by the Federal Reserve in itsmonetary policies may cause short-term interest rates toincrease and affect the Portfolio’s ability to maintain astable share price.

Redemption Risk. The Portfolio may need to sellportfolio securities to meet redemption requests. ThePortfolio could experience a loss when selling portfoliosecurities to meet redemption requests if there is (i)significant redemption activity by shareholders,including, for example, when a single investor or fewlarge investors make a significant redemption ofPortfolio shares, (ii) a disruption in the normaloperation of the markets in which the Portfolio buysand sells portfolio securities or (iii) the inability of thePortfolio to sell portfolio securities because suchsecurities are illiquid. In such events, the Portfolio couldbe forced to sell portfolio securities at unfavorable pricesin an effort to generate sufficient cash to pay redeemingshareholders. Although the Portfolio does not have theability to impose liquidity fees or temporarily suspendredemptions, the Portfolio may deny the payment ofredemption proceeds or suspend redemptions during itsliquidation when permitted by applicable regulations.

PerformanceThe following bar chart and table provide an indicationof the risks of investing in the Portfolio by showingchanges in the Portfolio’s performance from year to yearand by showing the Portfolio’s average annual returnsfor one-, five- and ten-year periods.

ThriventMultidimensionalIncome Portfolio $117 $459 $824 $1,852

Portfolio TurnoverThe Portfolio pays transaction costs, such ascommissions, when it buys and sells securities (or “turnsover” its portfolio). A higher portfolio turnover rate mayindicate higher transaction costs and may result inhigher taxes when Portfolio shares are held in a taxableaccount. These costs, which are not reflected in annualfund operating expenses or in the example, affect thePortfolio’s performance.

From inception on April 28, 2017 through the mostrecent fiscal year, the Portfolio’s portfolio turnover ratewas 172% of the average value of its portfolio.

Principal StrategiesThe Portfolio seeks to achieve its investment objectivesby allocating assets across multiple income and growthproducing asset classes and strategies. Debt securities inwhich the Portfolio invests include high yield, high riskbonds, notes, debentures and other debt obligationscommonly known as “junk bonds.” At the time ofpurchase, these high-yield securities are rated within orbelow the “BB” major rating category by S&P or the“Ba” major rating category by Moody’s or are unratedbut considered to be of comparable quality by theAdviser. The Portfolio also invests in leveraged loans,which are senior secured loans that are made by banksor other lending institutions to companies that are ratedbelow investment grade. In addition, the Portfolio mayinvest in investment-grade corporate bonds,asset-backed securities, mortgage-backed securities(including commercially backed ones), convertiblebonds, and U.S. dollar denominated emerging marketssovereign debt.

The Portfolio may invest in income-producing securitiesissued by closed-end funds (“CEFs”), publicly-tradedbusiness development companies (“BDCs”), masterlimited partnerships (“MLPs”), and exchange-traded

funds (“ETFs”). CEFs are investment companies thatissue a fixed number of shares that trade on a stockexchange or over-the-counter, typically at a premium ora discount to their net asset value. BDCs are publiclyheld investment funds that invest primarily in privateand thinly traded public U.S. businesses. MLPs arepublicly-traded limited partnerships that are limited bythe Internal Revenue Code to only apply to enterprisesthat engage in certain businesses, mostly pertaining tothe use of natural resources. ETFs are investmentcompanies generally designed to track the performanceof a securities or other index or benchmark. ThePortfolio may also pursue its investment strategy byinvesting in other mutual funds, including fundsmanaged by the Adviser or an affiliate.

The Portfolio may also invest in income-producingequity securities, including preferred stock and realestate investment trusts (“REITs”).

The Portfolio may utilize derivatives for investmentexposure or hedging purposes, including futuresagreements and credit default swap agreements onsecurity indexes. The Portfolio may enter intostandardized derivatives contracts traded on domestic orforeign securities exchanges, boards of trade, or similarentities, and non- standardized derivatives contractstraded in the over-the-counter market.

The Adviser uses fundamental, quantitative andtechnical investment research techniques to determinewhat to buy and sell. Fundamental techniques assess asecurity’s value based on an issuer’s financial profile,management, and business prospects while quantitativeand technical techniques involve a more data-orientedanalysis of financial information, market trends andprice movements.

Principal RisksThe Portfolio is subject to the following principalinvestment risks. Shares of the Portfolio will rise and fallin value and there is a risk that you could lose moneyby investing in the Portfolio. The Portfolio cannot becertain that it will achieve its investment objective.

Business Development Company (“BDC”) Risk.The value of a BDC’s investments will be affected byportfolio company specific performance as well as theoverall economic environment. Shares of BDCs maytrade at prices that reflect a premium above or adiscount below the investment company’s net assetvalue, which may be substantial. The Portfolio may beexposed to greater risk and experience higher volatilitythan would a portfolio that was not invested in BDCs.Additionally, most BDCs employ leverage which canmagnify the returns of underlying investments.

Closed-End Fund (“CEF”) Risk. Investments in CEFsare subject to various risks, including reliance onmanagement’s ability to meet a CEF’s investment

objective and to manage a CEF’s portfolio; fluctuation inthe market value of a CEF’s shares compared to thechanges in the value of the underlying securities thatthe CEF owns (i.e., trading at a discount or premium toits net asset value); and that CEFs are permitted toinvest in a greater amount of “illiquid” securities thantypical mutual funds. The Portfolio is subject to apro-rata share of the management fees and expenses ofeach CEF in addition to the Portfolio’s management feesand expenses, resulting in Portfolio shareholders subjectto higher expenses than if they invested directly inCEFs.

Convertible Securities Risk. Convertible securities aresubject to the usual risks associated with debt securities,such as interest rate risk and credit risk. Convertiblesecurities also react to changes in the value of thecommon stock into which they convert, and are thussubject to market risk. The Portfolio may also be forcedto convert a convertible security at an inopportunetime, which may decrease the Portfolio’s return.

Credit Risk. Credit risk is the risk that an issuer of adebt security to which the Portfolio is exposed may nolonger be able or willing to pay its debt. As a result ofsuch an event, the debt security may decline in priceand affect the value of the Portfolio.

Derivatives Risk. The use of derivatives (such asfutures and credit default swaps) involves additionalrisks and transaction costs which could leave thePortfolio in a worse position than if it had not usedthese instruments. The use of derivatives can lead tolosses because of adverse movements in the price orvalue of the underlying asset, index or rate, which maybe magnified by certain features of the contract.Changes in the value of the derivative may not correlateas intended with the underlying asset, rate or index, andthe Portfolio could lose much more than the originalamount invested. Derivatives can be highly volatile,illiquid and difficult to value. Certain derivatives mayalso be subject to counterparty risk, which is that theother party in the transaction will not fulfill itscontractual obligations due to its financial condition,market events, or other reasons.

ETF Risk. An ETF is subject to the risks of theunderlying investments that it holds. In addition, forindex-based ETFs, the performance of an ETF maydiverge from the performance of such index (commonlyknown as tracking error). ETFs are subject to fees andexpenses (like management fees and operatingexpenses) that do not apply to an index, and thePortfolio will indirectly bear its proportionate share ofany such fees and expenses paid by the ETFs in which itinvests.

Foreign and Emerging Markets Securities Risk.Foreign securities are generally more volatile than theirdomestic counterparts, in part because of higher

TSF-99

Page 144: Single Premium Immediate Variable Annuity · PDF fileSingle Premium Immediate Variable Annuity Issued between 7/26/1999 and 4/29/2016. Prospectuses April 30, 2017 Thrivent Variable

political and economic risks, lack of reliable informationand fluctuations in currency exchange rates. Foreignsecurities may also be more difficult to resell thancomparable U.S. securities because the markets forforeign securities are often less liquid. Even when aforeign security increases in price in its local currency,the appreciation may be diluted by adverse changes inexchange rates when the security’s value is converted toU.S. dollars. Foreign withholding taxes also may applyand errors and delays may occur in the settlementprocess for foreign securities. All of these risks may beheightened for securities of issuers located in, or withsignificant operations in, emerging market countries.

Growth Investing Risk. Growth style investingincludes the risk of investing in securities whose priceshistorically have been more volatile than othersecurities, especially over the short term. Growth stockprices reflect projections of future earnings or revenuesand, if a company’s earnings or revenues fall short ofexpectations, its stock price may fall dramatically.

High Yield Risk. High yield securities – commonlyknown as “junk bonds” – to which the Portfolio isexposed are considered predominantly speculative withrespect to the issuer’s continuing ability to makeprincipal and interest payments. If the issuer of thesecurity is in default with respect to interest or principalpayments, the value of the Portfolio may be negativelyaffected.

Interest Rate Risk. Interest rate risk is the risk thatprices of debt securities decline in value when interestrates rise for debt securities that pay a fixed rate ofinterest. Debt securities with longer durations (ameasure of price sensitivity of a bond or bond fund tochanges in interest rates) or maturities (i.e., the amountof time until a bond’s issuer must pay its principal orface value) tend to be more sensitive to changes ininterest rates than debt securities with shorter durationsor maturities. In addition, both mortgage-backed andasset-backed securities are sensitive to changes in therepayment patterns of the underlying security. If theprincipal payment on the underlying asset is repaidfaster or slower than the holder of the asset-backed ormortgage-backed security anticipates, the price of thesecurity may fall, particularly if the holder must reinvestthe repaid principal at lower rates or must continue tohold the security when interest rates rise. This effectmay cause the value of the Portfolio to decline andreduce the overall return of the Portfolio. Changes bythe Federal Reserve to monetary policies could affectinterest rates and the value of some securities.

Investment Adviser Risk. The Portfolio is activelymanaged and the success of its investment strategydepends significantly on the skills of the Adviser inassessing the potential of the investments in which thePortfolio invests. This assessment of investments may

prove incorrect, resulting in losses or poor performance,even in rising markets.

Investment in Other Investment Companies Risk.Investing in other investment companies, includingCEFs and BDCs, could result in the duplication ofcertain fees, including management and administrativefees, and may expose the Portfolio to the risks ofowning the underlying investments that the otherinvestment company holds.

Issuer Risk. Issuer risk is the possibility that factorsspecific to a company to which the Portfolio is exposedwill affect the market prices of the company’s securitiesand therefore the value of the Portfolio.

Leveraged Loan Risk. Leveraged loans (also known asbank loans) are subject to the risks typically associatedwith debt securities. In addition, leveraged loans, whichtypically hold a senior position in the capital structureof a borrower, are subject to the risk that a court couldsubordinate such loans to presently existing or futureindebtedness or take other action detrimental to theholders of leveraged loans. Leveraged loans are alsosubject to the risk that the value of the collateral, if any,securing a loan may decline, be insufficient to meet theobligations of the borrower, or be difficult to liquidate.Some leveraged loans are not as easily purchased or soldas publicly-traded securities and others are illiquid,which may make it more difficult for the Portfolio tovalue them or dispose of them at an acceptable price.Below investment-grade leveraged loans are typicallymore credit sensitive. In the event of fraud ormisrepresentation, the Portfolio may not be protectedunder federal securities laws with respect to leveragedloans that may not be in the form of “securities.” Thesettlement period for some leveraged loans may be morethan seven days.

Liquidity Risk. Liquidity is the ability to sell a securityrelatively quickly for a price that most closely reflectsthe actual value of the security. High-yield bonds have aless liquid resale market. In addition, dealer inventoriesof bonds are at or near historic lows in relation tomarket size, which has the potential to decreaseliquidity and increase price volatility in the fixedincome markets, particularly during periods ofeconomic or market stress. As a result, the Adviser mayhave difficulty selling or disposing of securities quicklyin certain markets or may only be able to sell theholdings at prices substantially less than what theAdviser believes they are worth.

Market Risk. Over time, securities markets generallytend to move in cycles with periods when securityprices rise and periods when security prices decline. Thevalue of the Portfolio’s investments may move withthese cycles and, in some instances, increase or decreasemore than the applicable market(s) as measured by thePortfolio’s benchmark index(es). The securities markets

may also decline because of factors that affect aparticular industry.

Master Limited Partnership Risk. An investment inan MLP exposes the Portfolio to the legal and tax risksassociated with investing in partnerships. MLPs mayhave limited financial resources, their securities may berelatively illiquid, and they may be subject to moreerratic price movements because of the underlyingassets they hold. Due to the tax requirements for MLPs,the income of many MLPs comes from energyinfrastructure. Risks inherent in the energyinfrastructure business include: sustained declines indemand for crude oil, natural gas and refined petroleumproducts, construction risk, changes in the regulatoryenvironment or other regulatory exposure, weather risk,risks associated with terrorist activity and interest raterisk.

Mortgage-Related and Other Asset-BackedSecurities Risk. The value of mortgage-related andasset-backed securities will be influenced by the factorsaffecting the housing market and the assets underlyingsuch securities. As a result, during periods of decliningasset value, difficult or frozen credit markets, swings ininterest rates, or deteriorating economic conditions,mortgage-related and asset-backed securities maydecline in value, face valuation difficulties, becomemore volatile and/or become illiquid.

Other Funds Risk. The performance of the Portfolio isdependent, in part, upon the performance of otherfunds manged by the Adviser or an affiliate (“OtherFunds”) in which the Portfolio may invest. As a result,the Portfolio is subject to the same risks as those facedby the Other Funds.

Portfolio Turnover Rate Risk. The Portfolio mayengage in active and frequent trading of portfoliosecurities in implementing its principal investmentstrategies. A high rate of portfolio turnover (100% ormore) involves correspondingly greater expenses whichare borne by the Portfolio and its shareholders and mayalso result in short-term capital gains taxable toshareholders.

Preferred Securities Risk. There are certainadditional risks associated with investing in preferredsecurities, including, but not limited to, preferredsecurities may include provisions that permit the issuer,at its discretion, to defer or omit distributions for astated period without any adverse consequences to theissuer; preferred securities are generally subordinated tobonds and other debt instruments in a company’scapital structure in terms of having priority to corporateincome and liquidation payments, and therefore will besubject to greater credit risk than more senior debtinstruments; preferred securities may be substantiallyless liquid than many other securities, such as commonstocks or U.S. Government securities; generally,

traditional preferred securities offer no voting rightswith respect to the issuing company unless preferreddividends have been in arrears for a specified number ofperiods, at which time the preferred security holdersmay elect a number of directors to the issuer’s board;and in certain varying circumstances, an issuer ofpreferred securities may redeem the securities prior to aspecified date.

Real Estate Investment Trust (“REIT”) Risk. REITsgenerally can be divided into three types: equity REITs,mortgage REITs, and hybrid REITs (which combine thecharacteristics of equity REITs and mortgage REITs).Equity REITs will be affected by changes in the values of,and income from, the properties they own, whilemortgage REITs may be affected by the credit quality ofthe mortgage loans they hold. All REIT types may beaffected by changes in interest rates. REITs are subject toadditional risks, including the fact that they aredependent on specialized management skills that mayaffect the REITs’ abilities to generate cash flows foroperating purposes and for making investordistributions. REITs may have limited diversificationand are subject to the risks associated with obtainingfinancing for real property. As with any investment,there is a risk that REIT securities and other real estateindustry investments may be overvalued at the time ofpurchase. In addition, a REIT can pass its incomethrough to its investors without any tax at the entitylevel if it complies with various requirements under theInternal Revenue Code. There is the risk, however, thata REIT held by the Portfolio will fail to qualify for thistax-free pass-through treatment of its income. Inaddition, due to recent changes in the tax laws, certaintax benefits of REITs may not be passed through tomutual fund shareholders. By investing in REITsindirectly through the Portfolio, in addition to bearing aproportionate share of the expenses of the Portfolio, youwill also indirectly bear similar expenses of the REITs inwhich the Portfolio invests.

Sovereign Debt Risk. Sovereign debt securities areissued or guaranteed by foreign governmental entities.These investments are subject to the risk that agovernmental entity may delay or refuse to pay interestor repay principal on its sovereign debt, due, forexample, to cash flow problems, insufficient foreigncurrency reserves, political considerations, the relativesize of the governmental entity’s debt position inrelation to the economy or the failure to put in placeeconomic reforms required by the InternationalMonetary Fund or other multilateral agencies.

Volatility Risk. Volatility risk is the risk that certaintypes of securities shift in and out of favor dependingon market and economic conditions as well as investorsentiment. The value of the Portfolio’s shares may beaffected by weak equity markets or changes in interestrate or bond yield levels. As a result, the value of the

The Portfolio may invest in exchange-traded funds(“ETFs”), which are investment companies generallydesigned to track the performance of a securities orother index or benchmark.

The Portfolio may also pursue its investment strategy byinvesting in other mutual funds, including fundsmanaged by the Adviser or an affiliate.

The Adviser uses fundamental, quantitative andtechnical investment research techniques to determinewhat to buy and sell. Fundamental techniques assess asecurity’s value based on an issuer’s financial profile,management, and business prospects while quantitativeand technical techniques involve a more data-orientedanalysis of financial information, market trends andprice movements.

Principal RisksThe Portfolio is subject to the following principalinvestment risks. Shares of the Portfolio will rise and fallin value and there is a risk that you could lose moneyby investing in the Portfolio. The Portfolio cannot becertain that it will achieve its investment objective.

Allocation Risk. The Portfolio’s investmentperformance depends upon how its assets are allocatedacross broad asset categories and applicable sub-classeswithin such categories. Some broad asset categories andsub-classes may perform below expectations or thesecurities markets generally over short and extendedperiods. In particular, underperformance in the fixedincome markets would have a material adverse effect onthe Portfolio’s total return given its significantallocation to fixed income securities. Therefore, aprincipal risk of investing in the Portfolio is that theallocation strategies used and the allocation decisionsmade will not produce the desired results.

Convertible Securities Risk. Convertible securities aresubject to the usual risks associated with debt securities,such as interest rate risk and credit risk. Convertiblesecurities also react to changes in the value of thecommon stock into which they convert, and are thussubject to market risk. The Portfolio may also be forcedto convert a convertible security at an inopportunetime, which may decrease the Portfolio’s return.

Credit Risk. Credit risk is the risk that an issuer of adebt security to which the Portfolio is exposed may nolonger be able or willing to pay its debt. As a result ofsuch an event, the debt security may decline in priceand affect the value of the Portfolio.

Derivatives Risk. The use of derivatives (such asfutures and credit default swaps) involves additionalrisks and transaction costs which could leave thePortfolio in a worse position than if it had not usedthese instruments. The use of derivatives can lead tolosses because of adverse movements in the price orvalue of the underlying asset, index or rate, which may

be magnified by certain features of the contract.Changes in the value of the derivative may not correlateas intended with the underlying asset, rate or index, andthe Portfolio could lose much more than the originalamount invested. Derivatives can be highly volatile,illiquid and difficult to value. Certain derivatives mayalso be subject to counterparty risk, which is that theother party in the transaction will not fulfill itscontractual obligations due to its financial condition,market events, or other reasons.

Emerging Markets Risk. The economic and politicalstructures of developing countries, in most cases, do notcompare favorably with the U.S. or other developedcountries in terms of wealth and stability, and theirfinancial markets often lack liquidity. Portfolioperformance will likely be negatively affected byportfolio exposure to countries in the midst of, amongother things, hyperinflation, currency devaluation,trade disagreements, sudden political upheaval, orinterventionist government policies. Significant buyingor selling actions by a few major investors may alsoheighten the volatility of emerging markets. Thesefactors make investing in emerging market countriessignificantly riskier than in other countries, and eventsin any one country could cause the Portfolio’s shareprice to decline.

ETF Risk. An ETF is subject to the risks of theunderlying investments that it holds. In addition, forindex-based ETFs, the performance of an ETF maydiverge from the performance of such index (commonlyknown as tracking error). ETFs are subject to fees andexpenses (like management fees and operatingexpenses) that do not apply to an index, and thePortfolio will indirectly bear its proportionate share ofany such fees and expenses paid by the ETFs in which itinvests.

Foreign Securities Risk. Foreign securities aregenerally more volatile than their domesticcounterparts, in part because of higher political andeconomic risks, lack of reliable information andfluctuations in currency exchange rates. Foreignsecurities may also be more difficult to resell thancomparable U.S. securities because the markets forforeign securities are often less liquid. Even when aforeign security increases in price in its local currency,the appreciation may be diluted by adverse changes inexchange rates when the security’s value is converted toU.S. dollars. Foreign withholding taxes also may applyand errors and delays may occur in the settlementprocess for foreign securities. All of these risks may beheightened for securities of issuers located in, or withsignificant operations in, emerging market countries.

High Yield Risk. High yield securities – commonlyknown as “junk bonds” – to which the Portfolio isexposed are considered predominantly speculative withrespect to the issuer’s continuing ability to make

principal and interest payments. If the issuer of thesecurity is in default with respect to interest or principalpayments, the value of the Portfolio may be negativelyaffected.

Interest Rate Risk. Interest rate risk is the risk thatprices of debt securities decline in value when interestrates rise for debt securities that pay a fixed rate ofinterest. Debt securities with longer durations (ameasure of price sensitivity of a bond or bond fund tochanges in interest rates) or maturities (i.e., the amountof time until a bond’s issuer must pay its principal orface value) tend to be more sensitive to changes ininterest rates than debt securities with shorter durationsor maturities. In addition, both mortgage-backed andasset-backed securities are sensitive to changes in therepayment patterns of the underlying security. If theprincipal payment on the underlying asset is repaidfaster or slower than the holder of the asset-backed ormortgage-backed security anticipates, the price of thesecurity may fall, particularly if the holder must reinvestthe repaid principal at lower rates or must continue tohold the security when interest rates rise. This effectmay cause the value of the Portfolio to decline andreduce the overall return of the Portfolio. Changes bythe Federal Reserve to monetary policies could affectinterest rates and the value of some securities.

Investment Adviser Risk. The Portfolio is activelymanaged and the success of its investment strategydepends significantly on the skills of the Adviser inassessing the potential of the investments in which thePortfolio invests. This assessment of investments mayprove incorrect, resulting in losses or poor performance,even in rising markets.

Issuer Risk. Issuer risk is the possibility that factorsspecific to a company to which the Portfolio is exposedwill affect the market prices of the company’s securitiesand therefore the value of the Portfolio.

Leveraged Loan Risk. Leveraged loans (also known asbank loans) are subject to the risks typically associatedwith debt securities. In addition, leveraged loans, whichtypically hold a senior position in the capital structureof a borrower, are subject to the risk that a court couldsubordinate such loans to presently existing or futureindebtedness or take other action detrimental to theholders of leveraged loans. Leveraged loans are alsosubject to the risk that the value of the collateral, if any,securing a loan may decline, be insufficient to meet theobligations of the borrower, or be difficult to liquidate.Some leveraged loans are not as easily purchased or soldas publicly-traded securities and others are illiquid,which may make it more difficult for the Portfolio tovalue them or dispose of them at an acceptable price.Below investment-grade leveraged loans are typicallymore credit sensitive. In the event of fraud ormisrepresentation, the Portfolio may not be protectedunder federal securities laws with respect to leveraged

loans that may not be in the form of “securities.” Thesettlement period for some leveraged loans may be morethan seven days.

Liquidity Risk. Liquidity is the ability to sell a securityrelatively quickly for a price that most closely reflectsthe actual value of the security. High-yield bonds andleveraged loans have a less liquid resale market. Inaddition, dealer inventories of bonds are at or nearhistoric lows in relation to market size, which has thepotential to decrease liquidity and increase pricevolatility in the fixed income markets, particularlyduring periods of economic or market stress. As a result,the Adviser may have difficulty selling or disposing ofsecurities quickly in certain markets or may only be ableto sell the holdings at prices substantially less than whatthe Adviser believes they are worth.

Market Risk. Over time, securities markets generallytend to move in cycles with periods when securityprices rise and periods when security prices decline. Thevalue of the Portfolio’s investments may move withthese cycles and, in some instances, increase or decreasemore than the applicable market(s) as measured by thePortfolio’s benchmark index(es). The securities marketsmay also decline because of factors that affect aparticular industry.

Mortgage-Related and Other Asset-BackedSecurities Risk. The value of mortgage-related andasset-backed securities will be influenced by the factorsaffecting the housing market and the assets underlyingsuch securities. As a result, during periods of decliningasset value, difficult or frozen credit markets, swings ininterest rates, or deteriorating economic conditions,mortgage-related and asset-backed securities maydecline in value, face valuation difficulties, becomemore volatile and/or become illiquid.

Other Funds Risk. The performance of the Portfolio isdependent, in part, upon the performance of otherfunds manged by the Adviser or an affiliate (“OtherFunds”) in which the Portfolio may invest. As a result,the Portfolio is subject to the same risks as those facedby the Other Funds.

Portfolio Turnover Rate Risk. The Portfolio mayengage in active and frequent trading of portfoliosecurities in implementing its principal investmentstrategies. A high rate of portfolio turnover (100% ormore) involves correspondingly greater expenses whichare borne by the Portfolio and its shareholders and mayalso result in short-term capital gains taxable toshareholders.

Real Estate Investment Trust (“REIT”) Risk. REITsgenerally can be divided into three types: equity REITs,mortgage REITs, and hybrid REITs (which combine thecharacteristics of equity REITs and mortgage REITs).Equity REITs will be affected by changes in the values of,and income from, the properties they own, while

3

TSF-106

Page 151: Single Premium Immediate Variable Annuity · PDF fileSingle Premium Immediate Variable Annuity Issued between 7/26/1999 and 4/29/2016. Prospectuses April 30, 2017 Thrivent Variable

mortgage REITs may be affected by the credit quality ofthe mortgage loans they hold. All REIT types may beaffected by changes in interest rates. REITs are subject toadditional risks, including the fact that they aredependent on specialized management skills that mayaffect the REITs’ abilities to generate cash flows foroperating purposes and for making investordistributions. REITs may have limited diversificationand are subject to the risks associated with obtainingfinancing for real property. As with any investment,there is a risk that REIT securities and other real estateindustry investments may be overvalued at the time ofpurchase. In addition, a REIT can pass its incomethrough to its investors without any tax at the entitylevel if it complies with various requirements under theInternal Revenue Code. There is the risk, however, thata REIT held by the Portfolio will fail to qualify for thistax-free pass-through treatment of its income. Inaddition, due to recent changes in the tax laws, certaintax benefits of REITs may not be passed through tomutual fund shareholders. By investing in REITsindirectly through the Portfolio, in addition to bearing aproportionate share of the expenses of the Portfolio, youwill also indirectly bear similar expenses of the REITs inwhich the Portfolio invests.

Sovereign Debt Risk. Sovereign debt securities areissued or guaranteed by foreign governmental entities.These investments are subject to the risk that agovernmental entity may delay or refuse to pay interestor repay principal on its sovereign debt, due, forexample, to cash flow problems, insufficient foreigncurrency reserves, political considerations, the relativesize of the governmental entity’s debt position inrelation to the economy or the failure to put in placeeconomic reforms required by the InternationalMonetary Fund or other multilateral agencies.

Volatility Risk. Volatility risk is the risk that certaintypes of securities shift in and out of favor dependingon market and economic conditions as well as investorsentiment. Bonds may exhibit price fluctuations due tochanges in interest rates or bond yield levels.

PerformanceThe following bar chart and table provide an indicationof the risks of investing in the Portfolio by showingchanges in the Portfolio’s performance from year to yearand by showing how the Portfolio’s average annualreturns for one-, five- and ten-year periods compared tobroad-based securities market indices. These indices arethe Bloomberg Barclays U.S. Mortgage-Backed SecuritiesIndex, which covers the mortgage-backed securitiescomponent of the Bloomberg Barclays U.S. AggregateBond Index, the Bloomberg Barclays U.S. High YieldBa/B 2% Issuer Capped Index, which represents theperformance of high yield corporate bonds rated Ba orB, with a maximum allocation of 2% to any one issuer,and the S&P/LSTA Leveraged Loan Index, which reflects

The bar chart includes the effects of Portfolio expenses,but not charges or deductions against your variablecontract, and assume that you sold your investment atthe end of the period. Because shares of the Portfolio areoffered through variable life insurance and variableannuity contracts, you should carefully review thevariable contract prospectus for information onapplicable charges and expenses. If the charges anddeductions against your variable contract were included,returns would be lower than those shown.

Effective August 16, 2013, based on approval of thePortfolio’s Board of Directors, the Portfolio’s investmentobjective and principal strategies were changed, whichhad the effect of converting the Portfolio from onewhich invested at least 80% of its assets inmortgage-related securities to one which invests in abroad range of fixed-income securities. At the sametime, the Portfolio’s name changed from ThriventMortgage Securities Portfolio to Thrivent OpportunityIncome Plus Portfolio. As a result, performanceinformation presented below with respect to periodsprior to August 16, 2013, reflects the performance of aninvestment portfolio that was materially different fromthe investment portfolio of Thrivent OpportunityIncome Plus Portfolio.

1 Year 3 Years 5 Years 10 Years

Thrivent Partner AllCap Portfolio $83 $259 $450 $1,002

Portfolio TurnoverThe Portfolio pays transaction costs, such ascommissions, when it buys and sells securities (or “turnsover” its portfolio). A higher portfolio turnover rate mayindicate higher transaction costs and may result inhigher taxes when Portfolio shares are held in a taxableaccount. These costs, which are not reflected in annualfund operating expenses or in the example, affect thePortfolio’s performance. During the most recent fiscalyear, the Portfolio’s portfolio turnover rate was 51% ofthe average value of its portfolio.

Principal StrategiesThe Portfolio’s principal strategy for achieving itsobjective is normally to invest the Portfolio’s assetsprimarily in common stocks.

FIAM LLC (“FIAM”), the Portfolio’s subadviser, is notconstrained by any particular investment style. At anygiven time, FIAM may tend to buy “growth” stocks or“value” stocks, or a combination of both types.

In buying and selling securities for the Portfolio, FIAMuses a disciplined approach that involvescomputer-aided, quantitative analysis supported byfundamental analysis. FIAM’s computer modelsystematically reviews thousands of stocks, using datasuch as historical earnings, dividend yield, earnings pershare, and other quantitative factors. Then, the issuersof potential investments are analyzed further usingfundamental factors such as growth potential, earningsestimates, and financial condition.

FIAM may use various techniques, such as buying andselling futures contracts and exchange-traded funds, toincrease or decrease the Portfolio’s exposure to changingsecurity prices or other factors that affect securityvalues. If FIAM’s strategies do not work as intended, thePortfolio may not achieve its objective.

Principal RisksThe Portfolio is subject to the following principalinvestment risks. Shares of the Portfolio will rise and fallin value and there is a risk that you could lose moneyby investing in the Portfolio. The Portfolio cannot becertain that it will achieve its investment objective.

ETF Risk. An ETF is subject to the risks of theunderlying investments that it holds. In addition, forindex-based ETFs, the performance of an ETF maydiverge from the performance of such index (commonlyknown as tracking error). ETFs are subject to fees andexpenses (like management fees and operatingexpenses) that do not apply to an index, and the

Portfolio will indirectly bear its proportionate share ofany such fees and expenses paid by the ETFs in which itinvests.

Futures Contract Risk. The value of a futurescontract tends to increase and decrease in tandem withthe value of the underlying instrument. The price offutures can be highly volatile; using them could lowertotal return, and the potential loss from futures canexceed the Portfolio’s initial investment in suchcontracts. In addition, the value of the futures contractmay not accurately track the value of the underlyinginstrument.

Growth Investing Risk. Growth style investingincludes the risk of investing in securities whose priceshistorically have been more volatile than othersecurities, especially over the short term. Growth stockprices reflect projections of future earnings or revenuesand, if a company’s earnings or revenues fall short ofexpectations, its stock price may fall dramatically.

Investment Adviser Risk. The Portfolio is activelymanaged and the success of its investment strategydepends significantly on the skills of the Adviser orsubadviser in assessing the potential of the investmentsin which the Portfolio invests. This assessment ofinvestments may prove incorrect, resulting in losses orpoor performance, even in rising markets.

Issuer Risk. Issuer risk is the possibility that factorsspecific to a company to which the Portfolio is exposedwill affect the market prices of the company’s securitiesand therefore the value of the Portfolio. Common stockof a company is subordinate to other securities issued bythe company. If a company becomes insolvent, interestsof investors owning common stock will be subordinatedto the interests of other investors in, and generalcreditors of, the company.

Large Cap Risk. Large-sized companies may be unableto respond quickly to new competitive challenges suchas changes in technology. They may also not be able toattain the high growth rate of successful smallercompanies, especially during extended periods ofeconomic expansion.

Liquidity Risk. Liquidity is the ability to sell a securityrelatively quickly for a price that most closely reflectsthe actual value of the security. Certain securities (i.e.,small-cap stocks) often have a less liquid resale market.As a result, the Adviser or subadviser may have difficultyselling or disposing of securities quickly in certainmarkets or only be able to sell the holdings at pricessubstantially less than what the Adviser or subadviserbelieves they are worth.

Market Risk. Over time, securities markets generallytend to move in cycles with periods when securityprices rise and periods when security prices decline. Thevalue of the Portfolio’s investments may move with

these cycles and, in some instances, increase or decreasemore than the applicable market(s) as measured by thePortfolio’s benchmark index(es). The securities marketsmay also decline because of factors that affect aparticular industry.

Small and Mid Cap Risk. Smaller, less seasonedcompanies often have greater price volatility, lowertrading volume, and less liquidity than larger, moreestablished companies. These companies tend to havesmall revenues, narrower product lines, lessmanagement depth and experience, small shares oftheir product or service markets, fewer financialresources, and less competitive strength than largercompanies. Such companies seldom pay significantdividends that could cushion returns in a falling market.

Value Investing Risk. Value style investing includesthe risk that stocks of undervalued companies may notrise as quickly as anticipated if the market doesn’trecognize their intrinsic value or if value stocks are outof favor.

Volatility Risk. Volatility risk is the risk that certaintypes of securities shift in and out of favor dependingon market and economic conditions as well as investorsentiment.

PerformanceThe following bar chart and table provide an indicationof the risks of investing in the Portfolio by showingchanges in the Portfolio’s performance from year to yearand by showing how the Portfolio’s average annualreturns for one-, five-, and ten-year periods compared toa broad-based securities market index. The index is theS&P Composite 1500 Index, which combines the S&P500 Index, the S&P MidCap 400 Index, and the S&PSmallCap 600 Index to cover approximately 90% of theU.S. market capitalization. Call 800-847-4836 or visitThrivent.com for performance results current to themost recent month-end.

The bar chart and table include the effects of Portfolioexpenses, but not charges or deductions against yourvariable contract, and assume that you sold yourinvestment at the end of the period. Because shares ofthe Portfolio are offered through variable life insuranceand variable annuity contracts, you should carefullyreview the variable contract prospectus for informationon applicable charges and expenses. If the charges anddeductions against your variable contract were included,returns would be lower than those shown.

Portfolio TurnoverThe Portfolio pays transaction costs, such ascommissions, when it buys and sells securities (or “turnsover” its portfolio). A higher portfolio turnover rate mayindicate higher transaction costs and may result inhigher taxes when Portfolio shares are held in a taxableaccount. These costs, which are not reflected in annualfund operating expenses or in the example, affect thePortfolio’s performance. During the most recent fiscalyear, the Portfolio’s portfolio turnover rate was 15% ofthe average value of its portfolio.

Principal StrategiesUnder normal circumstances, the Portfolio invests atleast 80% of its net assets (plus the amount of anyborrowing for investment purposes), at the time ofinitial purchase, in emerging market equities, includingcommon stock, preferred stock, convertible securities,depositary receipts and rights and warrants to buycommon stocks. A security is considered to be an“emerging market” security if issued by a company thatPortfolio management has determined meets one ormore of the following criteria:

• is organized under the laws of, or has its principaloffice in, an emerging market country;

• has its principal securities trading market in anemerging market country; and/or

• derives a majority of its annual revenue or earningsor assets from goods produced, sales made or servicesperformed in an emerging market country.

An “emerging market” country is any countrydetermined by the Adviser or subadviser to have anemerging market economy, considering factors such asthe country’s credit rating, its political and economicstability and the development of its financial andcapital markets. These emerging market countriesinclude every nation in the world except the U.S.,Canada, Israel, Japan, Australia, New Zealand, HongKong, Singapore and all nations typically consideredpart of Western Europe. At times, the Portfolio mayhave a significant amount of its assets invested in acountry or geographic region.

The Portfolio may also invest in equity securities ofissuers that are not tied economically to emergingmarket countries. The Portfolio may invest in securitiesdenominated in U.S. dollars and currencies of emergingmarket countries in which it may invest. The Portfoliotypically has full currency exposure to those markets inwhich it invests.

The Portfolio may invest in securities of any marketcapitalization, including small and mid-cap securities.

The Portfolio may invest in securities of any marketsector and may hold a significant amount of securitiesof companies, from time to time, within a single sectorsuch as financials.

The Portfolio’s subadviser, Aberdeen Asset ManagersLimited (“Aberdeen”), uses a disciplined investmentprocess based on its proprietary research to determinesecurity selection. Aberdeen seeks to identify “quality”companies, based on factors such as strength ofmanagement and business, that trade at reasonablevaluations, based on factors such as earnings growthand other key financial measurements. Aberdeen alsoconsiders how a company’s corporate governance andrisk management practices may affect that company’slong-term value. Aberdeen makes investments for thelong-term, although it may sell a security when itperceives a company’s business direction or growthprospects to have changed or the company’s valuationsare no longer attractive.

Should the Adviser determine that the Portfolio wouldbenefit from reducing the percentage of its net assetsinvested in emerging market equities from 80% to alesser amount, it will notify you at least 60 days prior tothe change.

Principal RisksThe Portfolio is subject to the following principalinvestment risks. Shares of the Portfolio will rise and fallin value and there is a risk that you could lose moneyby investing in the Portfolio. The Portfolio cannot becertain that it will achieve its investment objective.

Emerging Markets Risk. The economic and politicalstructures of developing countries, in most cases, do notcompare favorably with the U.S. or other developedcountries in terms of wealth and stability, and theirfinancial markets often lack liquidity. Portfolioperformance will likely be negatively affected byportfolio exposure to countries in the midst of, amongother things, hyperinflation, currency devaluation,trade disagreements, sudden political upheaval, orinterventionist government policies. Significant buyingor selling actions by a few major investors may alsoheighten the volatility of emerging markets. Thesefactors make investing in emerging market countriessignificantly riskier than in other countries, and events

in any one country could cause the Portfolio’s shareprice to decline.

Financial Sector Risk. To the extent that thefinancials sector continues to represent a significantportion of the Portfolio, the Portfolio will be sensitive tochanges in, and its performance may depend to agreater extent on, factors impacting this sector.Performance of companies in the financials sector maybe adversely impacted by many factors, including,among others, government regulations, economicconditions, credit rating downgrades, changes ininterest rates, and decreased liquidity in credit markets.The impact of more stringent capital requirements,recent or future regulation of any individual financialcompany or recent or future regulation of the financialssector as a whole cannot be predicted. In recent years,cyber attacks and technology malfunctions and failureshave become increasingly frequent in this sector andhave caused significant losses.

Foreign Currency Risk. The value of a foreigncurrency may decline against the U.S. dollar, whichwould reduce the dollar value of securities denominatedin that currency. The overall impact of such a decline offoreign currency can be significant, unpredictable, andlong lasting, depending on the currencies represented,how each one appreciates or depreciates in relation tothe U.S. dollar, and whether currency positions arehedged. Under normal conditions, the Portfolio doesnot engage in extensive foreign currency hedgingprograms. Further, exchange rate movements arevolatile, and it is not possible to effectively hedge thecurrency risks of many developing countries.

Foreign Securities Risk. Securities of foreigncompanies in which the Portfolio invests generally carrymore risk than securities of U.S. companies. Theeconomies and financial markets of certain regions –such as Latin America, Asia, Europe, and theMediterranean region – can be highly interdependentand may decline at the same time. Other risks resultfrom the varying stages of economic and politicaldevelopment of foreign countries; the differingregulatory environments, trading days, and accountingstandards of foreign markets; and higher transactioncosts. The Portfolio’s investment in any country couldbe subject to governmental actions such as capital orcurrency controls, nationalizing a company or industry,expropriating assets, or imposing punitive taxes thatwould have an adverse effect on security prices, andimpair the Portfolio’s ability to repatriate capital orincome.

Investment Adviser Risk. The Portfolio is activelymanaged and the success of its investment strategydepends significantly on the skills of the Adviser orsubadviser in assessing the potential of the investmentsin which the Portfolio invests. This assessment of

investments may prove incorrect, resulting in losses orpoor performance, even in rising markets.

Issuer Risk. Issuer risk is the possibility that factorsspecific to a company to which the Portfolio is exposedwill affect the market prices of the company’s securitiesand therefore the value of the Portfolio. Common stockof a company is subordinate to other securities issued bythe company. If a company becomes insolvent, interestsof investors owning common stock will be subordinatedto the interests of other investors in, and generalcreditors of, the company.

Large Cap Risk. Large-sized companies may be unableto respond quickly to new competitive challenges suchas changes in technology. They may also not be able toattain the high growth rate of successful smallercompanies, especially during extended periods ofeconomic expansion.

Liquidity Risk. Liquidity is the ability to sell a securityrelatively quickly for a price that most closely reflectsthe actual value of the security. Certain securities (i.e.,small-cap stocks and foreign securities) often have a lessliquid resale market. As a result, the Adviser orsubadviser may have difficulty selling or disposing ofsecurities quickly in certain markets or may only be ableto sell the holdings at prices substantially less than whatthe Adviser or subadviser believes they are worth.

Market Risk. Over time, securities markets generallytend to move in cycles with periods when securityprices rise and periods when security prices decline. Thevalue of the Portfolio’s investments may move withthese cycles and, in some instances, increase or decreasemore than the applicable market(s) as measured by thePortfolio’s benchmark index(es). The securities marketsmay also decline because of factors that affect aparticular industry.

Mid Cap Risk. Medium-sized companies often havegreater price volatility, lower trading volume, and lessliquidity than larger, more-established companies. Thesecompanies tend to have smaller revenues, narrowerproduct lines, less management depth and experience,smaller shares of their product or service markets, fewerfinancial resources, and less competitive strength thanlarger companies.

Preferred Securities Risk. There are certainadditional risks associated with investing in preferredsecurities, including, but not limited to, preferredsecurities may include provisions that permit the issuer,at its discretion, to defer or omit distributions for astated period without any adverse consequences to theissuer; preferred securities are generally subordinated tobonds and other debt instruments in a company’scapital structure in terms of having priority to corporateincome and liquidation payments, and therefore will besubject to greater credit risk than more senior debtinstruments; preferred securities may be substantially

less liquid than many other securities, such as commonstocks or U.S. Government securities; generally,traditional preferred securities offer no voting rightswith respect to the issuing company unless preferreddividends have been in arrears for a specified number ofperiods, at which time the preferred security holdersmay elect a number of directors to the issuer’s board;and in certain varying circumstances, an issuer ofpreferred securities may redeem the securities prior to aspecified date.

Small Cap Risk. Smaller, less seasoned companiesoften have greater price volatility, lower trading volume,and less liquidity than larger, more establishedcompanies. These companies tend to have smallrevenues, narrower product lines, less managementdepth and experience, small shares of their product orservice markets, fewer financial resources, and lesscompetitive strength than larger companies. Suchcompanies seldom pay significant dividends that couldcushion returns in a falling market.

Volatility Risk. Volatility risk is the risk that certaintypes of securities shift in and out of favor dependingon market and economic conditions as well as investorsentiment.

PerformanceThe following bar chart and table provide an indicationof the risks of investing in the Portfolio by showingchanges in the Portfolio’s performance from year to yearand by showing how the Portfolio’s average annualreturns for one- and five-year periods and sinceinception compared to a broad-based securities marketindex.

If the charges anddeductions against your variable contract were included,returns would be lower than those shown.

How a Portfolio has performed in the past is notnecessarily an indication of how it will perform in thefuture. Performance information provides someindication of the risks of investing in the Portfolio byshowing changes in the Portfolio’s performance overtime.

If variable contract charges were imposed,your expenses would be higher than those shown. Theexample assumes that you invest $10,000 in thePortfolio for the time periods indicated and thenredeem all of your shares at the end of those periods.The example also assumes that your investment has a5% return each year, and that the Portfolio’s operatingexpenses remain the same. Although your actual costmay be higher or lower, based on the foregoingassumptions, your cost would be:

1 Year 3 Years 5 Years 10 Years

Thrivent PartnerGrowth StockPortfolio $81 $252 $439 $978

Portfolio TurnoverThe Portfolio pays transaction costs, such ascommissions, when it buys and sells securities (or “turnsover” its portfolio). A higher portfolio turnover rate mayindicate higher transaction costs and may result inhigher taxes when Portfolio shares are held in a taxableaccount. These costs, which are not reflected in annualfund operating expenses or in the example, affect thePortfolio’s performance. During the most recent fiscalyear, the Portfolio’s portfolio turnover rate was 52% ofthe average value of its portfolio.

Principal StrategiesThe Portfolio’s principal strategy for achieving itsinvestment objectives under normal circumstances is toinvest at least 80% of net assets (plus the amount of anyborrowing for investment purposes) in common stocks.Should the Adviser determine that the Portfolio wouldbenefit from reducing the percentage of its assetsinvested in common stocks from 80% to a lesseramount, it will notify you at least 60 days prior to sucha change.

The Portfolio concentrates its investments in growthcompanies. The Portfolio’s subadviser, T. Rowe PriceAssociates, Inc. (“T. Rowe Price”), seeks investments incompanies that have the ability to pay increasingdividends through strong cash flow. The subadvisergenerally looks for companies with an above-averagerate of earnings growth and a lucrative niche in theeconomy that gives them the ability to sustain earningsmomentum even during times of slow economicgrowth. T. Rowe Price believes that when a companyincreases its earnings faster than both inflation and theoverall economy, the market will eventually reward itwith a higher stock price. The Portfolio may at timesinvest significantly in technology stocks.

In pursuing the Portfolio’s investment objectives, T.Rowe Price has the discretion to purchase somesecurities that do not meet its normal investmentcriteria, as described above, when it believes suchpurchase will provide an opportunity for substantialappreciation. These situations might arise when T. RowePrice believes a security could increase in value for avariety of reasons including a change in management,an extraordinary corporate event, a new productintroduction or innovation, or a favorable competitivedevelopment.

While the Portfolio invests primarily (at least 80%) incommon stocks, it may also invest in foreign stocks (upto 30% of total assets), and futures and options toobtain investment exposure or for hedging, in keepingwith the Portfolio’s objectives.

The Portfolio may sell securities for a variety of reasons,such as to secure gains, limit losses, or reposition assetsinto more promising opportunities.

Principal RisksThe Portfolio is subject to the following principalinvestment risks. Shares of the Portfolio will rise and fallin value and there is a risk that you could lose moneyby investing in the Portfolio. The Portfolio cannot becertain that it will achieve its investment objectives.

Derivatives Risk. The use of derivatives (such asfutures and options) involves additional risks andtransaction costs which could leave the Portfolio in aworse position than if it had not used theseinstruments. The use of derivatives can lead to lossesbecause of adverse movements in the price or value ofthe underlying asset, index or rate, which may bemagnified by certain features of the contract. Changesin the value of the derivative may not correlate asintended with the underlying asset, rate or index, andthe Portfolio could lose much more than the originalamount invested. Derivatives can be highly volatile,illiquid and difficult to value. Certain derivatives mayalso be subject to counterparty risk, which is that theother party in the transaction will not fulfill itscontractual obligations due to its financial condition,market events, or other reasons.

Foreign Securities Risk. To the extent the Portfolio isexposed to foreign securities, it is subject to various risksassociated with such securities. Foreign securities aregenerally more volatile than their domesticcounterparts, in part because of higher political andeconomic risks, lack of reliable information andfluctuations in currency exchange rates. Foreignsecurities may also be more difficult to resell thancomparable U.S. securities because the markets forforeign securities are often less liquid. Even when aforeign security increases in price in its local currency,the appreciation may be diluted by adverse changes inexchange rates when the security’s value is converted toU.S. dollars. Foreign withholding taxes also may applyand errors and delays may occur in the settlementprocess for foreign securities.

Growth Investing Risk. Growth style investingincludes the risk of investing in securities whose priceshistorically have been more volatile than othersecurities, especially over the short term. Growth stockprices reflect projections of future earnings or revenuesand, if a company’s earnings or revenues fall short ofexpectations, its stock price may fall dramatically.

Investment Adviser Risk. The Portfolio is activelymanaged and the success of the Portfolio’s investmentstrategy depends significantly on the skills of theAdviser or subadviser in assessing the potential of theinvestments in which the Portfolio invests. This

assessment of investments may prove incorrect,resulting in losses or poor performance, even in risingmarkets.

Issuer Risk. Issuer risk is the possibility that factorsspecific to a company to which the Portfolio is exposedwill affect the market prices of the company’s securitiesand therefore the value of the Portfolio. Common stockof a company is subordinate to other securities issued bythe company. If a company becomes insolvent, interestsof investors owning common stock will be subordinatedto the interests of other investors in, and generalcreditors of, the company.

Market Risk. Over time, securities markets generallytend to move in cycles with periods when securityprices rise and periods when security prices decline. Thevalue of the Portfolio’s investments may move withthese cycles and, in some instances, increase or decreasemore than the applicable market(s) as measured by thePortfolio’s benchmark index(es). The securities marketsmay also decline because of factors that affect aparticular industry.

Technology-Oriented Companies Risk. Commonstocks of companies that rely extensively on technology,science or communications in their productdevelopment or operations may be more volatile thanthe overall stock market and may or may not move intandem with the overall stock market. Technology,science and communications are rapidly changingfields, and stocks of these companies, especially ofsmaller or unseasoned companies, may be subject tomore abrupt or erratic market movements than thestock market in general. There are significantcompetitive pressures among technology-orientedcompanies and the products or operations of suchcompanies may become obsolete quickly. In addition,these companies may have limited product lines,markets or financial resources and the management ofsuch companies may be more dependent upon one or afew key people.

Volatility Risk. Volatility risk is the risk that certaintypes of securities shift in and out of favor dependingon market and economic conditions as well as investorsentiment. Growth style investing includes the risk ofinvesting in securities whose prices historically havebeen more volatile than other securities, especially overthe short term. Growth stock prices reflect projection offuture earnings or revenues and, if a company’s earningsor revenues fall short of expectations, its stock pricemay fall dramatically.

Thrivent Partner Healthcare PortfolioInvestment ObjectiveThrivent Partner Healthcare Portfolio (the �Portfolio�)seeks long-term capital growth.

Fees and ExpensesThis table describes the fees and expenses that you maypay if you buy and hold shares of the Portfolio. If youown a variable annuity contract or variable lifeinsurance contract, you will have additional expensesincluding mortality and expense risk charges. Pleaserefer to the prospectus for your variable contract foradditional information about charges for thosecontracts.

SHAREHOLDER FEES(fees paid directly from your investment)

Maximum Sales Charge (load) Imposed OnPurchases (as a percentage of offering price) N/A

Maximum Deferred Sales Charge (load) (as apercentage of the net asset value at time ofpurchase or redemption, whichever is lower) N/A

ANNUAL PORTFOLIO OPERATING EXPENSES(expenses that you pay each year as a percentage ofthe value of your investment)

Management Fees 0.83%

Other Expenses 0.10%

Total Annual Portfolio Operating Expenses 0.93%

Less Fee Waivers and/or ExpenseReimbursements1 0.05%

Total Annual Portfolio Operating Expenses AfterFee Waivers and/or Expense Reimbursements 0.88%

1 The Adviser has contractually agreed, through at least April 30,2019, to waive a portion of the management fees associated withthe shares of the Thrivent Partner Healthcare Portfolio equal in theaggregate to 0.05% of the average daily net assets. This contractualprovision, however, may be terminated before the indicatedtermination date upon the mutual agreement between theIndependent Directors of the Portfolio and the Adviser.

EXAMPLE This example is intended to help youcompare the cost of investing in the Portfolio with thecost of investing in other mutual funds. The Portfolio isan investment option for variable contracts, and theexample does not include charges imposed by variablecontracts. If variable contract charges were imposed,your expenses would be higher than those shown. Theexample assumes that you invest $10,000 in thePortfolio for the time periods indicated and thenredeem all of your shares at the end of those periods. Inaddition, the example for the 1 Year period reflects theeffect of the contractual fee waiver and/or expensereimbursement. The example also assumes that yourinvestment has a 5% return each year, and that the

Portfolio’s operating expenses remain the same.Although your actual cost may be higher or lower, basedon the foregoing assumptions, your cost would be:

1 Year 3 Years 5 Years 10 Years

Thrivent PartnerHealthcare Portfolio $90 $291 $510 $1,138

Portfolio TurnoverThe Portfolio pays transaction costs, such ascommissions, when it buys and sells securities (or “turnsover” its portfolio). A higher portfolio turnover rate mayindicate higher transaction costs and may result inhigher taxes when Portfolio shares are held in a taxableaccount. These costs, which are not reflected in annualfund operating expenses or in the example, affect thePortfolio’s performance. During the most recent fiscalyear, the Portfolio’s portfolio turnover rate was 212% ofthe average value of its portfolio.

Principal StrategiesUnder normal circumstances, the Portfolio will invest atleast 80% of its net assets (plus the amount of anyborrowing for investment purposes) in the securities ofcompanies that are engaged in the development,production or distribution of pharmaceutical, generic,biotechnology and medical technology products orservices (“healthcare companies”). Healthcarecompanies are those that derive at least 50% of theirannual revenues from the production of such productsand provision of such services or have at least 50% oftheir assets in such products or services. The Portfolioinvests primarily in equity securities of both U.S. andnon-U.S. companies (including American DepositaryReceipts and issuers in emerging markets) and, as anon-diversified fund under the Investment CompanyAct of 1940 (the “1940 Act”), focuses its investments inthe securities of a relatively few number of issuers. Inaddition, the Portfolio concentrates its investments inthe securities of companies in the healthcare industry,some of which may be small- and medium-sizedcompanies. Should the Adviser determine that thePortfolio would benefit from reducing the percentage ofits assets invested in the securities of healthcarecompanies from 80% to a lesser amount, it will notifyyou at least 60 days prior to the change.

BlackRock Investment Management, LLC, the Portfolio’ssubadviser, considers a variety of factors when choosinginvestments for the Portfolio, including (i) identifyingcompanies and industries that appear to have thepotential for above-average returns; and (ii) identifyingcompanies that are expected to show above-averagegrowth over the long-term, as well as those that appear

to be trading below their true worth. The Portfolio willgenerally sell a stock when, in the opinion of thesubadviser, the stock reaches its price target or if there isdeterioration in the company’s fundamentals, a changein macroeconomic outlook, technical deterioration,valuation issues, a need to rebalance the Portfolio or abetter opportunity elsewhere.

Principal RisksThe Portfolio is subject to the following principalinvestment risks. Shares of the Portfolio will rise and fallin value and there is a risk that you could lose moneyby investing in the Portfolio. The Portfolio cannot becertain that it will achieve its investment objective.

Emerging Markets Risk. The economic and politicalstructures of developing countries, in most cases, do notcompare favorably with the U.S. or other developedcountries in terms of wealth and stability, and theirfinancial markets often lack liquidity. Portfolioperformance will likely be negatively affected byportfolio exposure to countries in the midst of, amongother things, hyperinflation, currency devaluation,trade disagreements, sudden political upheaval, orinterventionist government policies. Significant buyingor selling actions by a few major investors may alsoheighten the volatility of emerging markets. Thesefactors make investing in emerging market countriessignificantly riskier than in other countries, and eventsin any one country could cause the Portfolio’s shareprice to decline.

Foreign Securities Risk. Foreign securities aregenerally more volatile than their domesticcounterparts, in part because of higher political andeconomic risks, lack of reliable information andfluctuations in currency exchange rates. Foreignsecurities may also be more difficult to resell thancomparable U.S. securities because the markets forforeign securities are often less liquid. Even when aforeign security increases in price in its local currency,the appreciation may be diluted by adverse changes inexchange rates when the security’s value is converted toU.S. dollars. Foreign withholding taxes also may applyand errors and delays may occur in the settlementprocess for foreign securities. All of these risks may beheightened for securities of issuers located in, or withsignificant operations in, emerging market countries.

Growth Investing Risk. Growth style investingincludes the risk of investing in securities whose priceshistorically have been more volatile than othersecurities, especially over the short term. Growth stockprices reflect projections of future earnings or revenuesand, if a company’s earnings or revenues fall short ofexpectations, its stock price may fall dramatically.

Healthcare Industry Risk. As a sector fund thatinvests primarily in the healthcare industry, thePortfolio is subject to the risk that the companies in that

industry are likely to react similarly to legislative orregulatory changes, adverse market conditions and/orincreased competition affecting their market segment.Due to the rapid pace of technological development,there is the risk that the products and servicesdeveloped by these companies may become rapidlyobsolete or have relatively short product cycles. There isalso the risk that the products and services offered bythese companies will not meet expectations or evenreach the marketplace.

Investment Adviser Risk. The Portfolio is activelymanaged and the success of its investment strategydepends significantly on the skills of the Adviser orsubadviser in assessing the potential of the investmentsin which the Portfolio invests. This assessment ofinvestments may prove incorrect, resulting in losses orpoor performance, even in rising markets.

Issuer Risk. Issuer risk is the possibility that factorsspecific to a company to which the Portfolio is exposedwill affect the market prices of the company’s securitiesand therefore the value of the Portfolio. Some factorsaffecting the performance of a company includedemand for the company’s products or services, thequality of management of the company and brandrecognition and loyalty. Common stock of a company issubordinate to other securities issued by the company. Ifa company becomes insolvent, interests of investorsowning common stock will be subordinated to theinterests of other investors in, and general creditors of,the company.

Market Risk. Over time, securities markets generallytend to move in cycles with periods when securityprices rise and periods when security prices decline. Thevalue of the Portfolio’s investments may move withthese cycles and, in some instances, increase or decreasemore than the applicable market(s) as measured by thePortfolio’s benchmark index(es). The securities marketsmay also decline because of factors that affect aparticular industry.

Non-Diversified Risk. The Portfolio is not“diversified” within the meaning of the 1940 Act. Thatmeans the Portfolio may invest a greater percentage ofits assets in the securities of any single issuer comparedto other funds. A non-diversified portfolio is generallymore susceptible than a diversified portfolio to the riskthat events or developments affecting a particular issueror industry will significantly affect the Portfolio’sperformance.

Small and Mid Cap Risk. Small- and medium-sizedcompanies often have greater price volatility, lowertrading volumes, and less liquidity than larger, moreestablished companies. These companies tend to havesmaller revenues, narrower product lines, lessmanagement depth and experience, smaller shares oftheir product or service markets, fewer financial

resources, and less competitive strength than largercompanies.

Value Investing Risk. Value style investing includesthe risk that stocks of undervalued companies may notrise as quickly as anticipated if the market doesn’trecognize their intrinsic value or if value stocks are outof favor.

Volatility Risk. Volatility risk is the risk that certaintypes of securities shift in and out of favor dependingon market and economic conditions as well as investorsentiment. Stocks of growth companies historically havebeen more volatile than other securities, especially overthe short term. Growth stock prices reflect projectionsof future earnings or revenues and if a company’searnings or revenues fall short of expectations its stockprice may fall dramatically.

PerformanceThe following bar chart and table provide an indicationof the risks of investing in the Portfolio by showingchanges in the Portfolio’s performance from year to yearand by showing how the Portfolio’s average annualreturns for one- and five-year periods and sinceinception compared to a broad-based securities marketindex. The index is the S&P Composite 1500® Index,which measures the performance of stocks in the S&P1500® Index that are classified as members of the GICS®

health care sector. The Portfolio no longer uses theMSCI World Healthcare Index, which is acapitalization-weighted index of selected health carestocks from around the world, because BlackRockInvestment Management, LLC replaced Sectoral AssetManagement Inc. (“Sectoral”) as the subadviser of thePortfolio on September 11, 2017. Performanceinformation presented below with respect to periodsprior to September 11, 2017 reflects the Portfolio’sperformance when managed by Sectoral. Call800-847-4836 or visit Thrivent.com for performanceresults current to the most recent month-end.

The bar chart includes the effects of Portfolio expenses,but not charges or deductions against your variablecontract, and assumes that you sold your investment atthe end of the period. Because shares of the Portfolio areoffered through variable life insurance and variableannuity contracts, you should carefully review thevariable contract prospectus for information onapplicable charges and expenses. If the charges anddeductions against your variable contract were included,returns would be lower than those shown.

How a Portfolio has performed in the past is notnecessarily an indication of how it will perform in thefuture. Performance information provides someindication of the risks of investing in the Portfolio byshowing changes in the Portfolio’s performance overtime.

Portfolio TurnoverThe Portfolio pays transaction costs, such ascommissions, when it buys and sells securities (or “turns

over” its portfolio). A higher portfolio turnover rate mayindicate higher transaction costs and may result inhigher taxes when Portfolio shares are held in a taxableaccount. These costs, which are not reflected in annualfund operating expenses or in the example, affect thePortfolio’s performance. During the most recent fiscalyear, the Portfolio’s portfolio turnover rate was 88% ofthe average value of its portfolio.

Principal StrategiesThe Portfolio seeks to achieve its objective by investingprimarily in equity and debt securities of issuersthroughout the world. The Portfolio seeks to diversify itsportfolio broadly among developed and emergingcountries and among multiple asset classes. Undernormal market conditions, the Portfolio invests at least40% of its net assets in foreign assets. If marketconditions are not deemed favorable by the Portfolio’sinvestment adviser, the Portfolio could invest a lowerpercentage, but at least 30% of its net assets in foreignassets. A foreign asset could be an investment in anissuer that is organized under the laws of a foreignjurisdiction; that is traded principally in a foreigncountry; that derives at least 50% of its revenues orprofits from goods produced or sold, investments made,or services performed in a foreign country or has at least50% of its assets in a foreign country; or that otherwiseexposes the Portfolio’s portfolio to the economicfortunes and risks of a foreign country.

The debt securities in which the Portfolio invests maybe of any maturity or credit quality and may includehigh-yield, high-risk bonds, notes, debentures and otherdebt obligations commonly known as “junk bonds.” Atthe time of purchase, these high-yield, high-risk debtsecurities are rated within or below the “BB” majorrating category by Standard & Poor’s or the “Ba” majorrating category by Moody’s or are unrated butconsidered to be of comparable quality. The interestrates of the Portfolio’s debt securities may be fixed,floating or subject to periodic reset provisions. The debtsecurities in which the Portfolio invests may includesecurities issued by sovereign entities in foreign andemerging market countries. Such sovereign entitiesinclude foreign and emerging market governments,their agencies and instrumentalities, or their centralbanks.

The Adviser will make asset allocation decisions amongthe various asset classes and has selected multiplesubadvisers to manage each such class, although theAdviser will directly manage the Portfolio’sinternational large-cap value assets and assets that areallocated to U.S. securities. The subadvisers investindependently of one another and use their ownmethodologies for selecting assets.

The Portfolio’s actual holdings in each broad assetcategory may be outside the applicable allocation rangefrom time to time due to differing investmentperformances among asset classes. These allocationsmay change without shareholder approval or advancenotice to shareholders to the extent consistent withapplicable law.

The Portfolio may also pursue its investment strategy byinvesting in other mutual funds, including fundsmanaged by the Adviser or an affiliate.

Principal Global Investors, LLC manages theinternational large-cap growth assets. Aberdeen AssetManagers Limited manages the emerging markets equityassets. Goldman Sachs Asset Management, L.P. managesthe international small- and mid-cap equities and theemerging markets debt assets. The Adviser manages theinternational large-cap value assets and the assetsallocated to U.S. securities.

Principal RisksThe Portfolio is subject to the following principalinvestment risks. Shares of the Portfolio will rise and fallin value and there is a risk that you could lose moneyby investing in the Portfolio. The Portfolio cannot becertain that it will achieve its investment objective.

Allocation Risk. The Portfolio’s investmentperformance depends upon how its assets are allocatedacross broad asset categories and applicable sub-classeswithin such categories. Some broad asset categories andsub-classes may perform below expectations or thesecurities markets generally over short and extendedperiods. Therefore, a principal risk of investing in thePortfolio is that the allocation strategies used and theallocation decisions made will not produce the desiredresults.

Credit Risk. Credit risk is the risk that an issuer of adebt security to which the Portfolio is exposed may nolonger be able or willing to pay its debt. As a result ofsuch an event, the debt security may decline in priceand affect the value of the Portfolio.

Emerging Markets Risk. The economic and politicalstructures of developing countries, in most cases, do notcompare favorably with the U.S. or other developedcountries in terms of wealth and stability, and theirfinancial markets often lack liquidity. Portfolioperformance will likely be negatively affected byportfolio exposure to countries in the midst of, among

other things, hyperinflation, currency devaluation,trade disagreements, sudden political upheaval, orinterventionist government policies. Significant buyingor selling actions by a few major investors may alsoheighten the volatility of emerging markets. Thesefactors make investing in emerging market countriessignificantly riskier than in other countries, and eventsin any one country could cause the Portfolio’s shareprice to decline.

Foreign Currency Risk. The value of a foreigncurrency may decline against the U.S. dollar, whichwould reduce the dollar value of securities denominatedin that currency. The overall impact of such a decline offoreign currency can be significant, unpredictable, andlong lasting, depending on the currencies represented,how each one appreciates or depreciates in relation tothe U.S. dollar, and whether currency positions arehedged. Under normal conditions, the Portfolio doesnot engage in extensive foreign currency hedgingprograms. Further, exchange rate movements arevolatile, and it is not possible to effectively hedge thecurrency risks of many developing countries.

Foreign Securities Risk. Securities of foreigncompanies in which the Portfolio invests generally carrymore risk than securities of U.S. companies. Theeconomies and financial markets of certain regions –such as Latin America, Asia, Europe, and theMediterranean region – can be highly interdependentand may decline at the same time. Other risks resultfrom the varying stages of economic and politicaldevelopment of foreign countries; the differingregulatory environments, trading days, and accountingstandards of foreign markets; and higher transactioncosts. The Portfolio’s investment in any country couldbe subject to governmental actions such as capital orcurrency controls, nationalizing a company or industry,expropriating assets, or imposing punitive taxes thatwould have an adverse effect on security prices, andimpair the Portfolio’s ability to repatriate capital orincome.

Growth Investing Risk. Growth style investingincludes the risk of investing in securities whose priceshistorically have been more volatile than othersecurities, especially over the short term. Growth stockprices reflect projections of future earnings or revenuesand, if a company’s earnings or revenues fall short ofexpectations, its stock price may fall dramatically.

High Yield Risk. High yield securities – commonlyknown as “junk bonds” – to which the Portfolio isexposed are considered predominantly speculative withrespect to the issuer’s continuing ability to makeprincipal and interest payments. If the issuer of thesecurity is in default with respect to interest or principalpayments, the value of the Portfolio may be negativelyaffected.

Interest Rate Risk. Interest rate risk is the risk thatprices of debt securities decline in value when interestrates rise for debt securities that pay a fixed rate ofinterest. Debt securities with longer durations (ameasure of price sensitivity of a bond or bond fund tochanges in interest rates) or maturities (i.e., the amountof time until a bond’s issuer must pay its principal orface value) tend to be more sensitive to changes ininterest rates than debt securities with shorter durationsor maturities. Changes by the Federal Reserve tomonetary policies could affect interest rates and thevalue of some securities.

Investment Adviser Risk. The Portfolio is activelymanaged and the success of its investment strategydepends significantly on the skills of the Adviser orsubadviser in assessing the potential of the investmentsin which the Portfolio invests. This assessment ofinvestments may prove incorrect, resulting in losses orpoor performance, even in rising markets.

Issuer Risk. Issuer risk is the possibility that factorsspecific to a company to which the Portfolio is exposedwill affect the market prices of the company’s securitiesand therefore the value of the Portfolio. Common stockof a company is subordinate to other securities issued bythe company. If a company becomes insolvent, interestsof investors owning common stock will be subordinatedto the interests of other investors in, and generalcreditors of, the company.

Large Cap Risk. Large-sized companies may be unableto respond quickly to new competitive challenges suchas changes in technology. They may also not be able toattain the high growth rate of successful smallercompanies, especially during extended periods ofeconomic expansion.

Liquidity Risk. Liquidity is the ability to sell a securityrelatively quickly for a price that most closely reflectsthe actual value of the security. Certain securities (i.e.,small-cap stocks and foreign securities) often have a lessliquid resale market. As a result, the Adviser orsubadviser may have difficulty selling or disposing ofsecurities quickly in certain markets or may only be ableto sell the holdings at prices substantially less than whatthe Adviser or subadviser believes they are worth.

Market Risk. Over time, securities markets generallytend to move in cycles with periods when securityprices rise and periods when security prices decline. Thevalue of the Portfolio’s investments may move withthese cycles and, in some instances, increase or decreasemore than the applicable market(s) as measured by thePortfolio’s benchmark index(es). The securities marketsmay also decline because of factors that affect aparticular industry.

Multi-Manager Risk. The investment styles employedby the subadvisers may not be complementary. Theinterplay of the various strategies employed by thesubadvisers may result in the Portfolio indirectly

holding positions in certain types of securities,industries or sectors. These positions may bedetrimental to a Portfolio’s performance dependingupon the performance of those securities and the overalleconomic environment. The multi-manager approachcould result in a high level of portfolio turnover,resulting in higher brokerage expenses and increased taxliability from a Portfolio’s realization of capital gains. Itis also possible that one subadviser could be selling aparticular security or security from a certain countrywhile another subadviser could be purchasing the samesecurity or a security from that same country.

Other Funds Risk. The performance of the Portfolio isdependent, in part, upon the performance of otherfunds manged by the Adviser or an affiliate (“OtherFunds”) in which the Portfolio may invest. As a result,the Portfolio is subject to the same risks as those facedby the Other Funds.

Small and Mid Cap Risk. Small- and medium-sizedcompanies often have greater price volatility, lowertrading volumes, and less liquidity than larger, moreestablished companies. These companies tend to havesmaller revenues, narrower product lines, lessmanagement depth and experience, smaller shares oftheir product or service markets, fewer financialresources, and less competitive strength than largercompanies.

Sovereign Debt Risk. Sovereign debt securities areissued or guaranteed by foreign governmental entities.These investments are subject to the risk that agovernmental entity may delay or refuse to pay interestor repay principal on its sovereign debt, due, forexample, to cash flow problems, insufficient foreigncurrency reserves, political considerations, the relativesize of the governmental entity’s debt position inrelation to the economy or the failure to put in placeeconomic reforms required by the InternationalMonetary Fund or other multilateral agencies.

Value Investing Risk. Value style investing includesthe risk that stocks of undervalued companies may notrise as quickly as anticipated if the market doesn’trecognize their intrinsic value or if value stocks are outof favor.

Volatility Risk. Volatility risk is the risk that certaintypes of securities shift in and out of favor dependingon market and economic conditions as well as investorsentiment. Growth style investing includes the risk ofinvesting in securities whose prices historically havebeen more volatile than other securities, especially overthe short term. Growth stock prices reflect projectionsof future earnings or revenues and, if a company’searnings or revenues fall short of expectations, its stockprice may fall dramatically.

Thrivent Real Estate Securities PortfolioInvestment ObjectiveThe Thrivent Real Estate Securities Portfolio (the�Portfolio�) seeks to provide long-term capitalappreciation and high current income.

Fees and ExpensesThis table describes the fees and expenses that you maypay if you buy and hold shares of the Portfolio. If youown a variable annuity contract or variable lifeinsurance contract, you will have additional expensesincluding mortality and expense risk charges. Pleaserefer to the prospectus for your variable contract foradditional information about charges for thosecontracts.

SHAREHOLDER FEES(fees paid directly from your investment)

Maximum Sales Charge (load) Imposed OnPurchases (as a percentage of offering price) N/A

Maximum Deferred Sales Charge (load) (as apercentage of the net asset value at time ofpurchase or redemption, whichever is lower) N/A

ANNUAL PORTFOLIO OPERATING EXPENSES(expenses that you pay each year as a percentage ofthe value of your investment)

Management Fees 0.75%

Other Expenses 0.10%

Total Annual Portfolio Operating Expenses 0.85%

EXAMPLE This example is intended to help youcompare the cost of investing in the Portfolio with thecost of investing in other mutual funds. The Portfolio isan investment option for variable contracts, and theexample does not include charges imposed by variablecontracts. If variable contract charges were imposed,your expenses would be higher than those shown. Theexample assumes that you invest $10,000 in thePortfolio for the time periods indicated and thenredeem all of your shares at the end of those periods.The example also assumes that your investment has a5% return each year, and that the Portfolio’s operatingexpenses remain the same. Although your actual costmay be higher or lower, based on the foregoingassumptions, your cost would be:

1 Year 3 Years 5 Years 10 Years

Thrivent Real EstateSecurities Portfolio $87 $271 $471 $1,049

Portfolio TurnoverThe Portfolio pays transaction costs, such ascommissions, when it buys and sells securities (or “turnsover” its portfolio). A higher portfolio turnover rate mayindicate higher transaction costs and may result inhigher taxes when Portfolio shares are held in a taxableaccount. These costs, which are not reflected in annualfund operating expenses or in the example, affect thePortfolio’s performance. During the most recent fiscalyear, the Portfolio’s portfolio turnover rate was 15% ofthe average value of its portfolio.

Principal StrategiesIn seeking to achieve its investment objective, thePortfolio focuses on income-producing common stocksand other equity securities of U.S. real estate companies.Under normal circumstances, the Portfolio invests atleast 80% of its net assets (plus any borrowings forinvestment purposes) in companies that are primarilyengaged in the real estate industry. This includescompanies such as real estate investment trusts (REITs)and other real estate related investments. A real estatecompany generally derives at least 50% of its revenuefrom real estate ownership, leasing, management,development, financing or sale of residential,commercial or industrial real estate—or has at least 50%of its assets in real estate. Should the Adviser determinethat the Portfolio would benefit from reducing thepercentage of assets invested in companies that areprimarily engaged in the real estate industry from 80%to a lesser amount, it will notify you at least 60 daysprior to such a change.

This Portfolio may invest up to 20% of its assets inequity and fixed income securities of companies whichare not principally engaged in the real estate industry orwhich are not income producing equity securities ofcompanies principally engaged in the U.S. real estateindustry.

The Portfolio may also pursue its investment strategy byinvesting in other mutual funds, including fundsmanaged by the Adviser or an affiliate.

Principal RisksThe Portfolio is subject to the following principalinvestment risks. Shares of the Portfolio will rise and fallin value and there is a risk that you could lose moneyby investing in the Portfolio. The Portfolio cannot becertain that it will achieve its investment objective.

Interest Rate Risk. Interest rate risk is the risk thatsecurity prices (equity or fixed income) decline in valuewhen interest rates rise. This effect of rising interestrates is generally more pronounced for high dividend

paying stock than for stocks that pay little or nodividends. This may cause the value of real estatesecurities to decline during periods of rising interestrates, which would reduce the overall return of thePortfolio. Changes by the Federal Reserve to monetarypolicies could affect interest rates and the value of somesecurities

Investment Adviser Risk. The Portfolio is activelymanaged and the success of its investment strategydepends significantly on the skills of the Adviser inassessing the potential of the investments in which thePortfolio invests. This assessment of investments mayprove incorrect, resulting in losses or poor performance,even in rising markets.

Issuer Risk. Issuer risk is the possibility that factorsspecific to a company to which the Portfolio is exposedwill affect the market prices of the company’s securitiesand therefore the value of the Portfolio. Common stockof a company is subordinate to other securities issued bythe company. If a company becomes insolvent, interestsof investors owning common stock will be subordinatedto the interests of other investors in, and generalcreditors of, the company.

Market Risk. Over time, securities markets generallytend to move in cycles with periods when securityprices rise and periods when security prices decline. Thevalue of the Portfolio’s investments may move withthese cycles and, in some instances, increase or decreasemore than the applicable market(s) as measured by thePortfolio’s benchmark index(es). The securities marketsmay also decline because of factors that affect aparticular industry.

Other Funds Risk. The performance of the Portfolio isdependent, in part, upon the performance of otherfunds manged by the Adviser or an affiliate (“OtherFunds”) in which the Portfolio may invest. As a result,the Portfolio is subject to the same risks as those facedby the Other Funds.

Real Estate Industry Risk. To the extent thePortfolio allocates assets to companies in the real estatebusiness, the Portfolio is subject to real estate industryrisk. Declines in real estate values, changes in interestrates or economic downturns can have a significantnegative effect on companies in the real estate industry.Other adverse changes could include, but are notlimited to, extended vacancies of properties, increasedcompetition, overbuilding and changes in zoning lawand government regulations.

Real Estate Investment Trust (“REIT”) Risk. REITsgenerally can be divided into three types: equity REITs,mortgage REITs, and hybrid REITs (which combine thecharacteristics of equity REITs and mortgage REITs).Equity REITs will be affected by changes in the values of,and income from, the properties they own, whilemortgage REITs may be affected by the credit quality of

the mortgage loans they hold. All REIT types may beaffected by changes in interest rates. REITs are subject toadditional risks, including the fact that they aredependent on specialized management skills that mayaffect the REITs’ abilities to generate cash flows foroperating purposes and for making investordistributions. REITs may have limited diversificationand are subject to the risks associated with obtainingfinancing for real property. As with any investment,there is a risk that REIT securities and other real estateindustry investments may be overvalued at the time ofpurchase. In addition, a REIT can pass its incomethrough to its investors without any tax at the entitylevel if it complies with various requirements under theInternal Revenue Code. There is the risk, however, thata REIT held by the Portfolio will fail to qualify for thistax-free pass-through treatment of its income. Inaddition, due to recent changes in the tax laws, certaintax benefits of REITs may not be passed through tomutual fund shareholders. By investing in REITsindirectly through the Portfolio, in addition to bearing aproportionate share of the expenses of the Portfolio, youwill also indirectly bear similar expenses of the REITs inwhich the Portfolio invests.

Volatility Risk. Volatility risk is the risk that certaintypes of securities shift in and out of favor dependingon market and economic conditions as well as investorsentiment.

PerformanceThe following bar chart and table provide an indicationof the risks of investing in the Portfolio by showingchanges in the Portfolio’s performance from year to yearand by showing how the Portfolio’s average annualreturns for one-, five-, and ten-year periods compared toa broad-based securities market index. The index is theS&P Composite 1500® Equity REITs Index, whichmeasures the performance of the stocks in the S&PComposite 1500® Index that are classified as membersof the GICS® Equity Real Estate Investment Trustsindustry. The Portfolio now compares its returns to theS&P Composite 1500® Equity REITs Index because thePortfolio’s complex no longer uses FTSE as an indexprovider. Call 800-847-4836 or visit Thrivent.com forperformance results current to the most recentmonth-end.

The bar chart includes the effects of Portfolio expenses,but not charges or deductions against your variablecontract, and assumes that you sold your investment atthe end of the period. Because shares of the Portfolio areoffered through variable life insurance and variableannuity contracts, you should carefully review thevariable contract prospectus for information onapplicable charges and expenses. If the charges anddeductions against your variable contract were included,returns would be lower than those shown.

Portfolio TurnoverThe Portfolio pays transaction costs, such ascommissions, when it buys and sells securities (or “turnsover” its portfolio). A higher portfolio turnover rate mayindicate higher transaction costs and may result inhigher taxes when Portfolio shares are held in a taxableaccount. These costs, which are not reflected in annualfund operating expenses or in the example, affect thePortfolio’s performance. Because the Portfolio had notyet commenced operations prior to the date of thisprospectus, the Portfolio’s portfolio turnover rate for themost recent fiscal year is not yet available.

Principal StrategiesUnder normal circumstances, the Portfolio invests atleast 80% of its net assets (plus the amount of anyborrowing for investment purposes) in equity securitiesof small companies. The Adviser focuses mainly in theequity securities of smaller U.S. companies which havemarket capitalizations equivalent to those companiesincluded in widely known indices such as the S&PSmallCap 600 Index, the MSCI USA Small Cap Index, orthe small company market capitalization classificationpublished by Lipper, Inc. These companies typicallyhave a market capitalization of less than $6 billion.Should the Adviser determine that the Portfolio wouldbenefit from reducing the percentage of its assetsinvested in equity securities of small companies stocksfrom 80% to a lesser amount, we will notify you at least60 days prior to the change.

The Portfolio seeks to achieve its investment objectiveby investing primarily in common stocks. The Adviseruses fundamental, quantitative, and technicalinvestment research techniques and focuses on stocks ofcompanies that it believes have demonstrated andbelieves will sustain above-average revenue and earningsgrowth over time, or which are expected to developrapid sales and earnings growth in the future whencompared to the economy and stock market as a whole.Many such companies are in the technology sector and

the Portfolio may at times have a higher concentrationin this industry.

The Portfolio may also pursue its investment strategy byinvesting in other mutual funds, including fundsmanaged by the Adviser or an affiliate.

The Adviser may sell securities for a variety of reasons,such as to secure gains, limit losses, or reposition assetsto more promising opportunities.

Principal RisksThe Portfolio is subject to the following principalinvestment risks. Shares of the Portfolio will rise and fallin value and there is a risk that you could lose moneyby investing in the Portfolio. The Portfolio cannot becertain that it will achieve its investment objective.

Growth Investing Risk. Growth style investingincludes the risk of investing in securities whose priceshistorically have been more volatile than othersecurities, especially over the short term. Growth stockprices reflect projections of future earnings or revenuesand, if a company’s earnings or revenues fall short ofexpectations, its stock price may fall dramatically.

Investment Adviser Risk. The Portfolio is activelymanaged and the success of its investment strategydepends significantly on the skills of the Adviser inassessing the potential of the investments in which thePortfolio invests. This assessment of investments mayprove incorrect, resulting in losses or poor performance,even in rising markets.

Issuer Risk. Issuer risk is the possibility that factorsspecific to a company to which the Portfolio is exposedwill affect the market prices of the company’s securitiesand therefore the value of the Portfolio. Common stockof a company is subordinate to other securities issued bythe company. If a company becomes insolvent, interestsof investors owning common stock will be subordinatedto the interests of other investors in, and generalcreditors of, the company.

Liquidity Risk. Liquidity is the ability to sell a securityrelatively quickly for a price that most closely reflectsthe actual value of the security. Small capitalizationstocks often have a less liquid resale market. As a result,the Adviser may have difficulty selling or disposing ofsecurities quickly in certain markets or may only be ableto sell the holdings at prices substantially less than whatthe Adviser believes they are worth.

Market Risk. Over time, securities markets generallytend to move in cycles with periods when securityprices rise and periods when security prices decline. Thevalue of the Portfolio’s investments may move withthese cycles and, in some instances, increase or decreasemore than the applicable market(s) as measured by thePortfolio’s benchmark index(es). The securities markets

may also decline because of factors that affect aparticular industry.

Other Funds Risk. The performance of the Portfolio isdependent, in part, upon the performance of otherfunds manged by the Adviser or an affiliate (“OtherFunds”) in which the Portfolio may invest. As a result,the Portfolio is subject to the same risks as those facedby the Other Funds.

Small Cap Risk. Smaller, less seasoned companiesoften have greater price volatility, lower trading volume,and less liquidity than larger, more establishedcompanies. These companies tend to have smallrevenues, narrower product lines, less managementdepth and experience, small shares of their product orservice markets, fewer financial resources, and lesscompetitive strength than larger companies. Suchcompanies seldom pay significant dividends that couldcushion returns in a falling market.

Technology-Oriented Companies Risk. Commonstocks of companies that rely extensively on technology,science or communications in their productdevelopment or operations may be more volatile thanthe overall stock market and may or may not move intandem with the overall stock market. Technology,science and communications are rapidly changingfields, and stocks of these companies, especially ofsmaller or unseasoned companies, may be subject tomore abrupt or erratic market movements than thestock market in general. There are significantcompetitive pressures among technology-orientedcompanies and the products or operations of suchcompanies may become obsolete quickly. In addition,these companies may have limited product lines,markets or financial resources and the management ofsuch companies may be more dependent upon one or afew key people.

Volatility Risk. Volatility risk is the risk that certaintypes of securities shift in and out of favor dependingon market and economic conditions as well as investorsentiment. Growth style investing includes the risk ofinvesting in securities whose prices historically havebeen more volatile than other securities, especially overthe short term. Growth stock prices reflect projection offuture earnings or revenues and, if a company’s earningsor revenues fall short of expectations, its stock pricemay fall dramatically.

Thrivent Small Cap Index PortfolioInvestment ObjectiveThrivent Small Cap Index Portfolio (the �Portfolio�)seeks capital growth that tracks the performance of theS&P SmallCap 600 Index.

Fees and ExpensesThis table describes the fees and expenses that you maypay if you buy and hold shares of the Portfolio. If youown a variable annuity contract or variable lifeinsurance contract, you will have additional expensesincluding mortality and expense risk charges. Pleaserefer to the prospectus for your variable contract foradditional information about charges for thosecontracts.

SHAREHOLDER FEES(fees paid directly from your investment)

Maximum Sales Charge (load) Imposed OnPurchases (as a percentage of offering price) N/A

Maximum Deferred Sales Charge (load) (as apercentage of the net asset value at time ofpurchase or redemption, whichever is lower) N/A

ANNUAL PORTFOLIO OPERATING EXPENSES(expenses that you pay each year as a percentage ofthe value of your investment)

Management Fees 0.20%

Other Expenses 0.07%

Total Annual Portfolio Operating Expenses 0.27%

EXAMPLE This example is intended to help youcompare the cost of investing in the Portfolio with thecost of investing in other mutual funds. The Portfolio isan investment option for variable contracts, and theexample does not include charges imposed by variablecontracts. If variable contract charges were imposed,your expenses would be higher than those shown. Theexample assumes that you invest $10,000 in thePortfolio for the time periods indicated and thenredeem all of your shares at the end of those periods.The example also assumes that your investment has a5% return each year, and that the Portfolio’s operatingexpenses remain the same. Although your actual costmay be higher or lower, based on the foregoingassumptions, your cost would be:

1 Year 3 Years 5 Years 10 Years

Thrivent Small CapIndex Portfolio $28 $87 $152 $343

Portfolio TurnoverThe Portfolio pays transaction costs, such ascommissions, when it buys and sells securities (or “turnsover” its portfolio). A higher portfolio turnover rate mayindicate higher transaction costs and may result inhigher taxes when Portfolio shares are held in a taxableaccount. These costs, which are not reflected in annualfund operating expenses or in the example, affect thePortfolio’s performance. During the most recent fiscalyear, the Portfolio’s portfolio turnover rate was 16% ofthe average value of its portfolio.

Principal StrategiesUnder normal circumstances, the Portfolio investssubstantially all of its assets (more than 80% of its netassets, plus the amount of any borrowings forinvestment purposes) in small company common stocksincluded in the S&P SmallCap 600 Index in theproportions in which they are represented in the Index.This is a passively managed Portfolio, which means thatthe Adviser does not choose the securities that make upthe Portfolio. The S&P SmallCap 600 Index is acapitalization-weighted index comprised of 600domestic small capitalization stocks chosen for marketsize, liquidity, and industry representation. Accordingly,the Portfolio invests in stocks of smaller companiesfrom a broad range of industries. The S&P SmallCap 600Index is adjusted quarterly, and when changes to theindex occur, the Adviser will attempt to replicate thesechanges within the Portfolio. However, any suchchanges may result in slight variations from time totime. The Portfolio may buy and sell equity indexfutures for investment exposure. For liquidity reasons,the Portfolio may invest to some degree in moneymarket instruments. The Portfolio may also pursue itsinvestment strategy by investing in other mutual funds,including funds managed by the Adviser or an affiliate.

Principal RisksThe Portfolio is subject to the following principalinvestment risks. Shares of the Portfolio will rise and fallin value and there is a risk that you could lose moneyby investing in the Portfolio. The Portfolio cannot becertain that it will achieve its investment objective.

Futures Contract Risk. The value of a futurescontract tends to increase and decrease in tandem withthe value of the underlying instrument. The price offutures can be highly volatile; using them could lowertotal return, and the potential loss from futures canexceed the Portfolio’s initial investment in suchcontracts. In addition, the value of the futures contractmay not accurately track the value of the underlyinginstrument.

Issuer Risk. Issuer risk is the possibility that factorsspecific to a company to which the Portfolio is exposedwill affect the market prices of the company’s securitiesand therefore the value of the Portfolio. Common stockof a company is subordinate to other securities issued bythe company. If a company becomes insolvent, interestsof investors owning common stock will be subordinatedto the interests of other investors in, and generalcreditors of, the company.

Liquidity Risk. Liquidity is the ability to sell a securityrelatively quickly for a price that most closely reflectsthe actual value of the security. Certain securities (i.e.,small-cap stocks) often have a less liquid resale market.As a result, the Adviser may have difficulty selling ordisposing of securities quickly in certain markets or mayonly be able to sell the holdings at prices substantiallyless than what the Adviser believes they are worth.

Market Risk. Over time, securities markets generallytend to move in cycles with periods when securityprices rise and periods when security prices decline. Thevalue of the Portfolio’s investments may move withthese cycles and, in some instances, increase or decreasemore than the applicable market(s) as measured by thePortfolio’s benchmark index(es). The securities marketsmay also decline because of factors that affect aparticular industry.

Other Funds Risk. The performance of the Portfolio isdependent, in part, upon the performance of otherfunds manged by the Adviser or an affiliate (“OtherFunds”) in which the Portfolio may invest. As a result,the Portfolio is subject to the same risks as those facedby the Other Funds.

Small Cap Risk. Smaller, less seasoned companiesoften have greater price volatility, lower trading volume,and less liquidity than larger, more establishedcompanies. These companies tend to have smallrevenues, narrower product lines, less managementdepth and experience, small shares of their product orservice markets, fewer financial resources, and lesscompetitive strength than larger companies. Suchcompanies seldom pay significant dividends that couldcushion returns in a falling market.

Volatility Risk. Volatility risk is the risk that certaintypes of securities shift in and out of favor dependingon market and economic conditions as well as investorsentiment.

These costs, which are not reflected in annualfund operating expenses or in the example, affect thePortfolio’s performance. During the most recent fiscalyear, the Portfolio’s portfolio turnover rate was 44% ofthe average value of its portfolio.

Principal StrategiesUnder normal circumstances, the Portfolio invests atleast 80% of its net assets (plus the amount of anyborrowing for investment purposes) in equity securitiesof small companies. The Adviser focuses mainly in theequity securities of smaller U.S. companies which havemarket capitalizations equivalent to those companiesincluded in widely known indices such as the S&PSmallCap 600 Index, MSCI USA Small Cap Index, or thesmall company market capitalization classificationspublished by Lipper, Inc. These companies typicallyhave a market capitalization of less than $6 billion.Should the Adviser determine that the Portfolio wouldbenefit from reducing the percentage of its assetsinvested in equity securities of small companies stocksfrom 80% to a lesser amount, we will notify you at least60 days prior to the change.

The Portfolio seeks to achieve its investment objectiveby investing primarily in common stocks. The Adviseruses fundamental, quantitative, and technicalinvestment research techniques to determine whatsecurities to buy and sell. Fundamental techniquesassess a security’s value based on an issuer’s financialprofile, management, and business prospects whilequantitative and technical techniques involve a moredata-oriented analysis of financial information, markettrends and price movements. The Adviser looks forsmall companies that, in its opinion:

• have an improving fundamental outlook;• have capable management; and• are financially sound.

The Portfolio may also pursue its investment strategy byinvesting in other mutual funds, including fundsmanaged by the Adviser or an affiliate.

The Adviser may sell securities for a variety of reasons,such as to secure gains, limit losses, or reposition assetsto more promising opportunities.
