  1. Chapter 7 Cost of capital

  2. Chapter Outline • The Cost of Capital: Introduction • The Cost of Equity (CAPM and DDM) • The Costs of Debt and Preferred Stock • The Weighted Average Cost of Capital • Divisional and Project Costs of Capital

  3. Why Cost of Capital is Important • Return earned on assets depends on the risk of those assets • The return to an investor is the same as the cost to the company • Cost of capital provides with an indication of how the market views the risk of assets • Knowing cost of capital can also help determine required return for capital budgeting projects

  4. Required Return • The required return is the same as the appropriate discount rate and is based on the risk of the cash flows • The required rate of return is used to calculate NPV • We need to earn at least the required return to compensate investors for the financing they have provided

  5. Cost of Equity • The cost of equity is the return required by equity investors given the risk of the cash flows from the firm • There are two major methods for determining the cost of equity • Dividend growth model (Gordon growth model) • SML or CAPM

  6. The Dividend Growth Model Approach • Can be rearranged to solve for RE

  7. Example • Suppose that a company is expected to pay a dividend of $1.50 per share next year. There has been a steady growth in dividends of 5.1% per year and the market expects that to continue. The current price is $25. What is the cost of equity? Solution: RE = 11.1%

  8. Example: Estimating the Dividend Growth Rate • One method for estimating the growth rate is to use the historical average • Year Dividend Percent Change • 1995 1.23 • 1996 1.30 5.7% • 1997 1.36 4.6% Geom. = 5.0864 • 1998 1.43 5.1% • 1999 1.50 4.9% Ar. Av = 5.0872 • Analysts’ forecast can be used

  9. Alternative Approach to Estimating Growth • If the company has a stable ROE, a stable dividend policy and is not planning on raising new external capital, then the following relationship can be used: • A company has a ROE of 15% and payout ratio is 35%. If management is not planning on raising additional external capital, what is its growth rate? Solution: g= 9.75% • g = Retention ratio x ROE

  10. Advantages and Disadvantages of DividendGrowth Model – easy to understand and use : • Only applicable to companies currently paying dividends • Not applicable if dividends aren’t growing at a reasonably constant rate • Extremely sensitive to the estimated growth rate – an increase in g of 1% increases the cost of equity by 1% • Does not explicitly consider risk

  11. The SML Approach (CAPM) • Use the following information to compute our cost of equity • Risk-free rate, Rf • Market risk premium, E(RM) – Rf • Systematic risk of asset,  E(RA) = Rf + A(E(RM) – Rf)

  12. SML example • Suppose the company has an equity beta of .58 and the current risk-free rate is 6.1%. If the expected market risk premium is 8.6%, what is the cost of equity capital? Solution: RE = 11.08% • Do both approaches have the same result?

  13. Advantages and Disadvantages of SML : • Explicitly adjusts for systematic risk • Applicable to all companies, as long as beta can be computed : • Have to estimate the expected market risk premium, which does vary over time • Have to estimate beta, which also varies over time • We are relying on the past to predict the future, which is not always reliable

  14. Cost of Equity • Suppose the company has a beta of 1.5. The market risk premium is expected to be 9% and the current risk-free rate is 6%. Dividends will grow at 6% per year and last dividend was $2. The stock is currently selling for $15.65. What is our cost of equity? • Using SML: RE = 19.5% • Using DGM: RE = 19.55%

  15. Cost of Debt • The cost of debt is the required return on a company’s debt • Usually the costof long-term debt or bonds only is taken into account • The required return is best estimated by computing the yield-to-maturity on the existing debt • Estimates of current rates based on the bond rating can be used • The cost of debt is NOT the coupon rate

  16. Cost of Debt example • Suppose you have a bond issue currently outstanding that has 25 years left to maturity. The coupon rate is 9% and coupons are paid semiannually. The bond is currently selling for $908.72 per $1000 bond. What is the cost of debt? Solution: RD = 10% (YTM)

  17. Cost of Preferred Stock • Preferred stock generally pays a constant dividend every period • Dividends are expected to be paid every period forever • Preferred stock is an annuity • RP = D / P0

  18. Cost of Preferred Stock example • A company has preferred stock that has an annual dividend of $3. If the current price is $25, what is the cost of preferred stock? Solution:RPE= = 12%

  19. The Weighted Average Cost of Capital (WACC) • Individual costs of capital are used to find cost of capital for the firm • WACC is the required return assets, based on the market’s perception of the risk of those assets • The weights are determined by how much of each type of financing that we use – target D/E ratio

  20. Capital Structure Weights • V = market value of the firm’s D + E • Weights • wE = E/V = percent financed with equity • wD = D/V = percent financed with debt

  21. Capital Structure Weights example • Suppose you have a market value of equity equal to $500 million and a market value of debt = $475 million. • What are the capital structure weights? Solution: WD = =.4872 WE= = .5128

  22. Taxes and the WACC • We are concerned with after-tax cash flows, so the effect of taxes on the various costs of capital has to be considered • Interest expense reduces tax liability • Reduction in taxes reduces cost of debt • After-tax cost of debt = RD(1-TC) • Dividends are not tax deductible, so there is no tax impact on the cost of equity WACC = wERE + wDRD(1-TC)

  23. WACC (1) • Equity Information • 50 million shares • $80 per share • Beta = 1.15 • Market risk premium = 9% • Risk-free rate = 5% • Debt Information • $1 billion in outstanding debt (face value) • Current quote = 110 • Coupon rate = 9%, semiannual coupons • 15 years to maturity • Tax rate = 40%

  24. WACC (2) What is the cost of equity? RE =15.35% (by SML) What is the cost of debt? RD =7.85 (YTM) What is the after-tax cost of debt? 7.85*(1-.4)=4.71

  25. WACC (3) • What are the capital structure weights? • E=80*50mil= 4bln • D=1.1bln (110% of face) V= 5.1bln • What is the WACC? • WACC=4/5.1*15.35 + 1.1/5.1*4.71= • = 12.0392% + 1.0159 = 13.0551

  26. Divisional and Project Costs of Capital • Using the WACC as discount rate is only appropriate for projects that have the same risk as the firm’s current operations • If we are looking at a project that has NOT the same risk as the firm, then the appropriate discount rate for that project has to be determined • Divisions also often require separatediscount rates because they have different levels of risk

  27. Using WACC for All Projects example • What would happen if we use the WACC for all projects regardless of risk? • Assume the WACC = 15% Project Required Return IRR A 20% 17% B 15% 18% C 10% 12%

  28. The Pure Play Approach The pure play approach = use of a WACC that is unique to a particular project • Find one or more companies that specialize in the product or service that we are considering • Compute the beta for each company • Take an average • Use that beta along with the CAPM to find the appropriate return for a project of that risk • Often difficult to find pure play companies

  29. Subjective Approach • Consider the project’s risk relative to the firm overall • If the project is more risky than the firm, use a discount rate greater than the WACC • If the project is less risky than the firm, use a discount rate less than the WACC • You may still accept projects that you shouldn’t and reject projects you should accept, but your error rate should be lower than not considering differential risk at all
