Introduction
1. Corporate Finance – how decision making affects “value”.
2. Corporate finance is not a number “game”.
3. Focus: (a) practical issues that arise in valuation, (b) taxes, (c) incentives of different stakeholders.

Capital Budgeting Example
• Capital Budgeting Decision– Suppose you had the opportunity to buy a
tbill which would be worth $400,000 one year from today.• Interest rates on tbills are a risk free
7%.– What would you be willing to pay for this
investment?
$400,000 / (1.07) = $373,832
PV today:0 1 2
-$400,000

Cost of Capital
• Capital Budgeting Decision– Suppose you are offered a construction
deal with similar cost and payoff.– An important concept in finance is that a
risky dollar is worth less than a safe dollar. – You are told that the risk is quantified by
the cost of capital, which is 12%.
NPV= -350,000+400,000/1.12 = $7,142

Calculating Returns
Suppose you bought 100 shares of BCE one year ago today at $25. Over the last year, you received $20 in dividends (= 20 cents per share × 100 shares). At the end of the year, the stock sells for $30. How did you do?

How does this relate to cost of capital?
• Suppose there is an investment project which you know has the same risk as Standard and Poor’s Composite Index.
• What rate should you use?

Average Stock Returns and Risk-Free Returns
• The Risk Premium is the additional return (over and above the risk-free rate) resulting from bearing risk.
• One of the most significant observations of stock (and bond) market data is this long-run excess of security return over the risk-free return.
• The historical risk premium was 7.6% for the US.

Measuring Risk
Variance - Average value of squared deviations from mean. A measure of volatility.
Standard Deviation – Square root of variance. A measure of volatility.

Risk Statistics
There is no universally agreed-upon definition of risk. A large enough sample drawn from a normal distribution looks like a bell-shaped curve.

Diversification
• The variance (risk) of the security’s return can be broken down into:– Systematic (Market) Risk– Unsystematic (diversifiable) Risk
The Effect of Diversification:– unsystematic risk will significantly diminish in
large portfolios– systematic risk is not affected by
diversification since it affects all securities in any large portfolio
![Page 26: Slides Set1](https://reader033.fdocuments.net/reader033/viewer/2022061520/55cf8f15550346703b98c2a2/html5/thumbnails/26.jpg)

Portfolio Risk as a Function of the Number of Stocks in the Portfolio

In a large portfolio the variance terms are effectively diversified away, but the covariance terms are not.
Thus diversification can eliminate some, but not all of the risk of individual securities.

Beta and Unique Risk
Market Portfolio - Portfolio of all assets in the economy. In practice a broad stock market index, such as the S&P Composite, is used to represent the market.
Beta - Sensitivity of a stock’s return to the return on the market portfolio.

Definition of Risk When Investors Hold the Market Portfolio
• Researchers have shown that the best measure of the risk of a security in a large portfolio is the beta ()of the security.
• Beta measures the responsiveness of a security to movements in the market portfolio.

Markowitz Portfolio Theory
• Given a certain level of risk, investors prefer stocks with higher returns.
• Given a certain level of return, investors prefer less risk.
• By combining stocks into a portfolio, one can achieve different combinations of return & standard deviation.
• Correlation coefficients are crucial for ability to reduce risk in portfolio.

CAPM versus Reality
1. Do investors care about mean and variance?
2. Is there a security that is risk-free?
3. Short selling?
4. Transaction costs?
5. Most important: homogeneous expectations?

Because stockholders can reinvest the dividend in risky financial assets, the expected return on a capital-budgeting project should be at least as great as the expected return on a financial asset of comparable risk.
A firm with excess cash can either pay a dividend or make a capital investment

Suppose the Conglomerate Company has a cost of capital, based on the CAPM, of 17%. The risk-free rate is 4%, the market risk premium is 10%, and the firm’s beta is 1.3.
17% = 4% + 1.3 × [14% – 4%]
This is a breakdown of the company’s investment projects:1/3 Automotive retailer = 2.0
1/3 Computer Hard Drive Mfr. = 1.3

Using an Industry Beta
• It is frequently argued that one can better estimate a firm’s beta by involving the whole industry.
• If you believe that the operations of the firm are similar to the operations of the rest of the industry, you should use the industry beta.
• If you believe that the operations of the firm are fundamentally different from the operations of the rest of the industry, you should use the firm’s beta.
![Page 76: Slides Set1](https://reader033.fdocuments.net/reader033/viewer/2022061520/55cf8f15550346703b98c2a2/html5/thumbnails/76.jpg)
76
Problems with Industry Beta
One must make sure that the firm is comparable to other industry both in its operation and its financing.
Question: Consider Grand Sport, Inc., which is currently all-equity and has a beta of 0.90. The firm has decided to lever up to a capital structure of 50% debt and 50% equity. Since the firm will remain in the same industry, its asset beta should remain 0.90.
Assuming a zero beta for its debt, what should the equity beta be?

Beware of Fudge Factors
• Common practice to make adjustments to discount rate to offset worries.
Example:
1) A new drug won’t get FDA approval and won’t be able to go on the market.
2) Unexpected weather condition would hurt the crop.

Determinants of Beta
• Business Risk– Cyclicality of Revenues
– Operating Leverage
• Financial Risk– Financial Leverage

79
Cyclicality of Revenues
• Highly cyclical stocks have high betas.– Empirical evidence suggests that retailers
and automotive firms fluctuate with the business cycle.
– Transportation firms and utilities are less dependent upon the business cycle.

Operating Leverage
• The degree of operating leverage measures how sensitive a firm (or project) is to its fixed costs.
• Operating leverage increases as fixed costs rise and variable costs fall.
• Operating leverage magnifies the effect of cyclicality on beta.
• The degree of operating leverage is given by:

Chapter 9: Q9You run a perpetual encabulator machine, which generates revenues averaging $20 million per year. Raw material costs are 50 percent of revenues. These costs are variable – they are always proportional to revenues. There are no other operating costs. The cost of capital is 9 percent. Your firm’s long-term borrowing rate is 6 percent. Now you are approached by Studebaker Capital Corp., which proposes a fixed-price contract to supply raw materials at $10 million per year for 10 years.
a. What happens to the operating leverage and business risk of the encabulator machine if you agree to this fixed-price contact?
b. Calculate the present value of the encabulator machine with and without the fixed-price contract?

Long lived assets and discount rates
Example (from text): The scientists at Vegetron have come up with an electric mop and are ready to go ahead with pilot production. The preliminary phase will take one year and costs $125k. Management feels that there is only a 50% chance that the pilot production will be successful. If the project fails, the project will be dropped. If the project succeeds Vegetron will build a $1million plant that would generate an expected annual cash flow in perpetuity of $250k. Rf=7%, Risk Premium=9%. Regular projects of the firm have a beta of 0.33, however due to the 50% probability of failure management assumes a beta of 2 for the project.
1. What is NPV? 2. Is management correct about its approach for the NPV
calculation?

International Projects
• Investment projects abroad may be safer than similar domestic investments.
• Remember: Beta measures risk relative to investor’s portfolio (a good question would be to ask who is the investor of the company?)
• Not clear why home bias persists so strongly (perhaps information, transaction costs, etc.)
![Page 92: Slides Set1](https://reader033.fdocuments.net/reader033/viewer/2022061520/55cf8f15550346703b98c2a2/html5/thumbnails/92.jpg)
92
What is Liquidity?
• The idea that the expected return on a stock and the firm’s cost of capital are positively related to risk is fundamental.
• Recently a number of academics have argued that the expected return on a stock and the firm’s cost of capital are negatively related to the liquidity of the firm’s shares as well.
• The trading costs of holding a firm’s shares include brokerage fees, the bid-ask spread, and market impact costs.
![Page 93: Slides Set1](https://reader033.fdocuments.net/reader033/viewer/2022061520/55cf8f15550346703b98c2a2/html5/thumbnails/93.jpg)
93
Liquidity, Expected Returns, and the Cost of Capital
• The cost of trading an illiquid stock reduces the total return that an investor receives.
• Investors thus will demand a high expected return when investing in stocks with high trading costs.
• This high expected return implies a high cost of capital to the firm.
![Page 94: Slides Set1](https://reader033.fdocuments.net/reader033/viewer/2022061520/55cf8f15550346703b98c2a2/html5/thumbnails/94.jpg)

95
Liquidity and Adverse Selection
• There are a number of factors that determine the liquidity of a stock.
• One of these factors is adverse selection.• This refers to the notion that traders with better
information can take advantage of specialists and other traders who have less information.
• The greater the heterogeneity of information, the wider the bid-ask spreads, and the higher the required return on equity.
![Page 96: Slides Set1](https://reader033.fdocuments.net/reader033/viewer/2022061520/55cf8f15550346703b98c2a2/html5/thumbnails/96.jpg)
96
What the Corporation Can Do
• The corporation has an incentive to lower trading costs since this would result in a lower cost of capital.
• A stock split would increase the liquidity of the shares.
• A stock split would also reduce the adverse selection costs thereby lowering bid-ask spreads.

What the Corporation Can Do
• Companies can also facilitate stock purchases through the Internet.
• Direct stock purchase plans and dividend reinvestment plans handled on-line allow small investors the opportunity to buy securities cheaply.
• The companies can also disclose more information, especially to security analysts, to narrow the gap between informed and uninformed traders. This should reduce spreads.

Summary and Conclusions• The expected return on any capital budgeting
project should be at least as great as the expected return on a financial asset of comparable risk. Otherwise the shareholders would prefer the firm to pay a dividend.
• The expected return on any asset is dependent upon .
• A project’s required return depends on the project’s .
• A project’s can be estimated by considering comparable industries or the cyclicality of project revenues and the project’s operating and financial leverage.

Jones Family Mini-Case
Executive summary:• The wildcat oil well is going to cost $5 million.• The Jones geologists says there’s only 30% chance of a dry hole.• If oil is found, the expectation is for 300 barrels of crude oil per day
(at a price of $25 per barrel)• Sales will start next year.• Production and shipping costs are $10 per barrel (Mr. Jones argues
that they are fixed).• Production will start declining at 5% every year.• Oil prices expected to grow at 2.5% per year, and pumping will
continue for 15 years.• The interest rate is 6%, the beta is 0.8, and the risk premium is 7%.

Chapter 10: Decision Trees• A fundamental problem in NPV analysis is
dealing with uncertain future outcomes.• There is usually a sequence of decisions in
NPV project analysis.• Decision trees are used to identify the
sequential decisions in NPV analysis.• Decision trees allow us to graphically represent
the alternatives available to us in each period and the likely consequences of our actions.
• This graphical representation helps to identify the best course of action.

Stewart Pharmaceuticals • The Stewart Pharmaceuticals Corporation is considering
investing in developing a drug that cures the common cold.
• A corporate planning group, including representatives from production, marketing, and engineering, has recommended that the firm go ahead with the test and development phase.
• This preliminary phase will last one year and cost $1 billion. Furthermore, the group believes that there is a 60% chance that tests will prove successful.
• If the initial tests are successful, Stewart Pharmaceuticals can go ahead with full-scale production. This investment phase will cost $1,600 million. Production will occur over the next four years.

107
Real Options
• One of the fundamental insights of modern finance theory is that options have value.
• The phrase “We are out of options” is surely a sign of trouble.
• Because corporations make decisions in a dynamic environment, they have options that should be considered in project valuation.
![Page 108: Slides Set1](https://reader033.fdocuments.net/reader033/viewer/2022061520/55cf8f15550346703b98c2a2/html5/thumbnails/108.jpg)
108
Options
The Option to Expand• Static analysis implicitly assumes that the scale of the
project is fixed.• If we find a positive NPV project, we should consider the
possibility of expanding the project to get a larger NPV.• For example,the option to expand has value if demand
turns out to be higher than expected.• All other things being equal, we underestimate NPV if we
ignore the option to expand.The Option to Delay• Has value if the underlying variables are changing with a favourable trend.

109
The Option to Expand: Example
• Imagine a start-up firm, Campusteria, Inc. which plans to open private (for-profit) dining clubs on university campuses.
• The test market will be your campus, and if the concept proves successful, expansion will follow nationwide.
• Nationwide expansion, if it occurs, will occur in year four.
• The start-up cost of the test dining club is only $30,000 (this covers leaseholder improvements and other expenses for a vacant restaurant near campus).

The Option to Expand: Valuing a Start-Up
• Note that while the Campusteria test site has a negative NPV, its negativity is relatively small.
• If we expand, we project opening 20 Campusterias in year four and the size of the project may grow 20 folds.
• The value of the project is in the option to expand. • If we hit it big, we will be in a position to score large.• We won’t know if this has value if we do not try. Thus, it
seems that we may want to take on this test project and see what it delivers.

112
Discounted Cash Flows and Options
• We can calculate the market value of a project as the sum of the NPV of the project without options and the value of the managerial options implicit in the project.
M = NPV + Opt
A good example would be comparing the desirability of a specialized machine versus a more versatile machine. If they both cost about the same and last the same amount of time the more versatile machine is more valuable because it comes with options.

113
The Option to Abandon: Example• The option to abandon a project has value if demand
turns out to be lower than expected.• Suppose that we are drilling an oil well. The drilling rig
costs $300 today and in one year the well is either a success or a failure.
• The outcomes are equally likely. The discount rate is 10%.
• The PV of the successful payoff at time one is $575.• The PV of the unsuccessful payoff at time one is $0.

The Option to Delay: Example
• Consider the above project, which can be undertaken in any of the next 4 years. The discount rate is 10 percent. The present value of the benefits at the time the project is launched remain constant at $25,000, but since costs are declining the NPV at the time of launch steadily rises.
• The best time to launch the project is in year 2—this schedule yields the highest NPV when judged today.
