- 3. Copyright 2004 McGraw-Hill AustraliaPty Ltd18-3Chapter Objectives• Apply the dividend growth model approach and the SMLapproach to determine the cost of equity.• Estimate values for the costs of debt and preference shares.• Calculate the WACC.• Discuss alternative approaches to estimating a discount rate.• Understand the effects of flotation costs on WACC and theNPV of a project.
- 4. Copyright 2004 McGraw-Hill AustraliaPty Ltd18-4The Cost of Capital: Preliminaries• Vocabulary—the following all mean the same thing:– required return– appropriate discount rate– cost of capital.• The cost of capital is an opportunity cost—it depends onwhere the money goes, not where it comes from.• The assumption is made that a firm’s capital structure is fixed—a firm’s cost of capital then reflects both the cost of debtand the cost of equity.
- 5. Copyright 2004 McGraw-Hill AustraliaPty Ltd18-5Cost of Equity• The cost of equity is the return required byequity investors given the risk of the cashflows from the firm.• There are two major methods for determining thecost of equity:– Dividend growth model– SML or CAPM.

- 9. Copyright 2004 McGraw-Hill AustraliaPty Ltd18-9The Dividend Growth ModelApproachAdvantages• Easy to use and understand.Disadvantages• Only applicable to companies paying dividends.• Assumes dividend growth is constant.• Cost of equity is very sensitive to growth estimate.• Ignores risk.
- 10. Copyright 2004 McGraw-Hill AustraliaPty Ltd18-10The SML ApproachRequired return on a risky investment is dependent on threefactors:– the risk-free rate, Rf– the market risk premium, E(RM) – Rf– the systematic risk of the asset relative to the average, β[ ]fMEfE RRRR −×+= β
- 11. Copyright 2004 McGraw-Hill AustraliaPty Ltd18-11Example—Cost of Equity Capital:SML Approach• Obtain the risk-free rate (Rf) from financial press—many use the 1-year Treasury note rate, say, 6 per cent.• Obtain estimates of market risk premium and security beta:– historical risk premium = 7.94 per cent (Officer, 1989)– beta—historicalinvestment information servicesestimate from historical data• Assume the beta is 1.40.

- 13. Copyright 2004 McGraw-Hill AustraliaPty Ltd18-13The SML ApproachAdvantages• Adjusts for risk.• Accounts for companies that don’t have a constant dividend.Disadvantages• Requires two factors to be estimated: the market riskpremium and the beta co-efficient.• Uses the past to predict the future, which may not beappropriate.
- 14. Copyright 2004 McGraw-Hill AustraliaPty Ltd18-14The Cost of Debt• The cost of debt, RD, is the interest rate on new borrowing.• RD is observable:– yields on currently outstanding debt– yields on newly-issued similarly-rated bonds.• The historic cost of debt is irrelevant—why?
- 15. Copyright 2004 McGraw-Hill AustraliaPty Ltd18-15Example—Cost of DebtIshta Co. sold a 20-year, 12 per cent bond 10 yearsago at par.

- 16. Copyright 2004 McGraw-Hill AustraliaPty Ltd18-16The Cost of Preference Shares• Preference shares pay a constant dividend every period.• Preference shares are a perpetuity, so the cost is:• Notice that the cost is simply the dividend yield.0PDRp =
- 17. Copyright 2004 McGraw-Hill AustraliaPty Ltd18-17Example—Cost of Preference Shares• An $8 preference share issue was sold 10 years ago. It sellsfor $120 per share today.• The dividend yield today is $8.00/$120 = 6.67 per cent, sothis is the cost of the preference share issue.
- 18. Copyright 2004 McGraw-Hill AustraliaPty Ltd18-18The Weighted Average Cost of CapitalLet: E = the market value of equity = no.of outstanding shares × sharepriceD = the market value of debt = no. ofoutstanding bonds × priceThen: V = E + DSo: E/V + D/V = 100%That is: The firm’s capital structure weightsare E/V and D/V.
- 19. Copyright 2004 McGraw-Hill AustraliaPty Ltd18-19The Weighted Average Cost ofCapital• Interest payments on debt are tax deductible, so the after-taxcost of debt is:• Dividends on preference shares and ordinary shares are nottax-deductible so tax does not affect their costs.• The weighted average cost of capital is therefore:( )CD TR 1debtofcosttax-After −×=( ) ( ) ( )CDE TRVDRVE 1WACC −××+×=

- 25. Copyright 2004 McGraw-Hill AustraliaPty Ltd18-25WACC• The WACC for a firm reflects the risk and the target capitalstructure to finance the firm’s existing assets as a whole.• WACC is the return that the firm must earn on its existingassets to maintain the value of its shares.• WACC is the appropriate discount rate to use for cash flowsthat are similar in risk to the firm.
- 26. Copyright 2004 McGraw-Hill AustraliaPty Ltd18-26Divisional and Project Costs ofCapital• When is the WACC the appropriate discount rate?– When the project’s risk is about the same as the firm’srisk.• Other approaches to estimating a discount rate:– divisional cost of capital—used if a company has morethan one division with different levels of risk– pure play approach—a WACC that is unique to aparticular project is used– subjective approach—projects are allocated to specificrisk classes which, in turn, have specified WACCs.
