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. 1 Chapter 7 Risk, Return and the Cost of Capital Final objective: Estimating the opportunity cost of capital. Explain and calculate Expected return Security risk Diversification Portfolio risk beta. 2 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 -$400,000 investment? PV today: 0 1 2 $400,000 / (1.07) = $373,832 3 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 4 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? 5 Holding Period Returns The holding period return is the return that an investor would get when holding an investment over a period of n years, when the return during year i is given as ri: holding period return (1 r1 ) (1 r2 ) (1 rn ) 1 6 The Future Value of an Investment of $1 in 1957: Evidence from Canada 1000 $1 (1 r1957 ) (1 r1958) (1 r2003) $86.17 $42.91 $20.69 10 Common Stocks Long Bonds T-Bills 0.1 1957 1962 1967 1972 1977 1982 1987 1992 1997 2002 7 An Investment of $1 in 1900: US evidence $100,000 $10,000 Common Stock 15,578 US Govt Bonds $1,000 147 61 $100 $10 2004 $1 19 00 19 10 19 20 19 30 19 40 19 50 19 60 19 70 19 80 19 90 20 00 Dollars T-Bills Start of Year 8 An Investment of $1 in 1900: US evidence Real Returns $1,000 719 Equities Bonds Bills Dollars $100 $10 6.81 2.80 Start of Year 2004 19 00 19 10 19 20 19 30 19 40 19 50 19 60 19 70 19 80 19 90 20 00 $1 9 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? 10 Rates of Return 1900-2003 Stock Market Index Returns Percentage Return 80% 60% 40% 20% 0% -20% 1900 1920 1940 1960 1980 2000 -40% -60% Year Source: Ibbotson Associates 11 Measuring Risk Histogram of Annual Stock Market Returns # of Years 24 24 19 20 15 16 10 12 3 2 50 to 60 30 to 40 20 to 30 10 to 20 0 to 10 -10 to 0 -20 to -10 Return % -30 to -20 1 -40 to -30 0 1 -50 to -40 4 4 40 to 50 8 13 12 12 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 longrun excess of security return over the riskfree return. • The historical risk premium was 7.6% for the US. 13 Average Market Risk Premia (by country) 10.7 Italy UK 10 Japan Germany 9.3 France Ireland Australia Canada 8.6 South Africa Spain 8.2 Sweden Switzerland Country 7.6 8.1 USA 5.9 6.6 Netherlands 5.9 6.4 Average 5.1 5.8 4.3 4.7 5.3 6.3 Belgium 11 10 9 8 7 6 5 4 3 2 1 0 Denmark Risk premium, % 14 Measuring Risk Variance - Average value of squared deviations from mean.

Diversifiable Risk; Nonsystematic Risk; Firm Specific Risk; Unique Risk Portfolio risk Nondiversifiable risk; Systematic Risk; Market Risk n Thus diversification can eliminate some, but not all of the risk of individual securities. 26 Beta and Unique Risk 1. Total risk = diversifiable risk + market risk 2.

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. 28 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 (b)of the security. • Beta measures the responsiveness of a security to movements in the market portfolio. bi Cov( Ri , RM ) ( RM ) 2 29 Chapter 8 Risk and Return • Markowitz Portfolio Theory • Risk and Return Relationship • Validity and the Role of the CAPM 30 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. 31 Markowitz Portfolio Theory Expected Returns and Standard Deviations vary given different weighted combinations of the stocks Expected Return (%) Coca Cola 40% in Coca Cola Exxon Mobil Standard Deviation 32 Efficient Frontier Example Stocks ABC Corp Big Corp 28 42 Correlation Coefficient = .4 % of Portfolio Avg Return 60% 15% 40% 21% 33 Efficient Frontier Each half egg shell represents the possible weighted combinations for two stocks.

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 b = 2.0 1/3 Computer Hard Drive Mfr. b = 1.3 1/3 Electric Utility b = 0.6 average b of assets = 1.3 When evaluating a new electrical generation investment, which cost of capital should be used? 65 SML IRR Project Capital Budgeting & Project Risk 24% Investments in hard drives or auto retailing should have higher discount rates. 17% 10% Firm’s risk (beta) 0.6 1.3 2.0 r = 4% + 0.6×(14% – 4% ) = 10% 10% reflects the opportunity cost of capital on an investment in electrical generation, given the unique risk of the project. 66 Project IRR Capital Budgeting & Project Risk The SML can tell us why: SML Incorrectly accepted negative NPV projects RF βFIRM ( R M RF ) Hurdle rate rf bFIRM Incorrectly rejected positive NPV projects Firm’s risk (beta) 67 Measuring Betas Theoretically, the calculation of beta is straightforward: Cov( Ri , RM ) σ im β 2 Var ( RM ) σM Problem 1: Betas may vary over time. 68 Measuring Betas Dell Computer Price data: May 91- Nov 97 R2 = .10 B = 1.87 Slope determined from plotting the line of best fit. 69 Measuring Betas Dell Computer Price data: Dec 97 - Apr 04 R2 = .27 B = 1.61 Slope determined from plotting the line of best fit. 70 Measuring Betas General Motors Price data: May 91- Nov 97 R2 = .07 B = 0.72 Slope determined from plotting the line of best fit. 71 Measuring Betas General Motors R2 = .29 GM return (%) Price data: Dec 97 - Apr 04 B = 1.21 Slope determined from plotting the line of best fit. 72 Estimated Betas Beta Burlington Northern & Santa Fe CSX Transportation Norfolk Southern Union Pacific Corp Industry portfolio equity 0.53 0.58 0.47 0.47 0.49 Standard Error 0.2 0.23 0.28 0.19 0.18 73 Beta Stability RISK CLASS % IN SAME CLASS 5 YEARS LATER % WITHIN ONE CLASS 5 YEARS LATER 10 (High betas) 35 69 9 18 54 8 16 45 7 13 41 6 14 39 5 14 42 4 13 40 3 16 45 2 21 61 1 (Low betas) 40 62 Source: Sharpe and Cooper (1972) 74 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. 75 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 allequity 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? 76 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. 77 Determinants of Beta • Business Risk – Cyclicality of Revenues – Operating Leverage • Financial Risk – Financial Leverage 78 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. 79 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: Change in EBIT Sales DOL EBIT Change in Sales 80 Operating Leverage $ Total costs Fixed costs EBIT Volume Fixed costs Volume Operating leverage increases as fixed costs rise and variable costs fall. 81 Chapter 9: Q5 The following table shows estimates of the risk of two well-known Canadian Stocks STD R^2 Beta STD Beta Alcan 24 0.15 0.69 0.21 Inco 29 0.22 1.04 0.26 a.

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.

Given a risk free rate of 6%, a market premium of 8%, and beta of .75, what is the PV of the project?.. Now assume that the cash flows change, but are RISK FREE. What is the new PV? The difference between the 100 and the certainty equivalent (94.6) is 5.7%…this % can be considered the annual premium on a risky cash flow Risky cash flow certainty equivalent cash flow 1.057 89 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? 90 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.) 91 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. 92 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. 93 Liquidity and the Cost of Capital Liquidity An increase in liquidity, i.e., a reduction in trading costs, lowers a firm’s cost of capital. 94 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. 95 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. • This idea is a new one and empirical evidence is not yet in. 96 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. 97 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 b. • A project’s required return depends on the project’s b. • A project’s b can be estimated by considering comparable industries or the cyclicality of project revenues and the project’s operating and financial leverage. 98 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%. 99 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. 100 Example of Decision Tree Open circles represent decisions to be made. “A” Pay wizard $1000? Study finance “B” Filled circles represent receipt of information e.g., a test score in this class. “C” Do not study The lines leading away “D” from the circles represent the alternatives. “F” 101 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. 102 Production will occur over the next four years.

Success Test Invest NPV $3,433.75m Do not invest NPV = $0 Failure Do not test NPV $91.461m NPV $0 Invest 105 Stewart Pharmaceutical: Decision to Test • Let’s move back to the first stage, where the decision boils down to the simple question: should we invest? • The expected payoff evaluated at date 1 is: Expected Prob. Payoff Payoff Prob. payoff sucess given success failure given failure Expected payoff .60 $3,433.75 .40 $0 $2,060.25 • The NPV evaluated at date 0 is: NPV $1,000 $2,060.25 $872.95 1.10 So we should test. 106 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. 107 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. 108 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). 109 Campusteria pro forma Income Statement Investment Year 0 Revenues Years 1-4 $60,000 Variable Costs ($42,000) Fixed Costs ($18,000) Depreciation ($7,500) Pretax profit ($7,500) Tax shield 34% $2,550 –$4,950 Net Profit Cash Flow –$30,000 4 $2,550 $2,550 NPV $30,000 $21,916.84 t t 1 (1.10) We plan to sell 25 meal plans at $200 per month with a 12-month contract. Variable costs are projected to be $3,500 per month. Fixed costs (the lease payment) are projected to be $1,500 per month. We can depreciate (straight line) our capitalized leaseholder improvements. 110 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. 111 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. 112 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. 113 The Option to Abandon: Example (continued) Traditional NPV analysis would indicate rejection of the project. Expected = Prob. × Successful + Prob. × Failure Payoff Success Payoff Failure Payoff Expected = (0.50×$575) + (0.50×$0) = $287.50 Payoff NPV = –$300 + $287.50 1.10 = –$38.64 114 The Option to Abandon: Example Traditional NPV analysis overlooks the option to abandon. Success: PV = $575 Sit on rig; stare at empty hole: PV = $0. Drill $300 Failure Do not drill NPV $0 Sell the rig; salvage value = $250 The firm has two decisions to make: drill or not, abandon or115 stay. The Option to Abandon: Example (continued) • When we include the value of the option to abandon, the drilling project should proceed: Expected = Prob. × Successful + Prob. × Failure Payoff Success Payoff Failure Payoff Expected = (0.50×$575) + (0.50×$250) = $412.50 Payoff NPV = –$300 + $412.50 1.10 = $75.00 116 Valuation of the Option to Abandon • Recall that 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.

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.118 Option issues to consider Things to remember in these types of analysis: • Cost of the testing • Expected future cash flows given the outcome of the test • Probability of success of the testing • Discount rate 119
