4. The cost of retained earnings If a firm cannot invest retained earnings to earn a rate of return the required rate of return on retained earnings, it should return those funds to its stockholders. The cost of equity using the CAPM approach The current risk-free rate of return (rRF) is 4.67% while the market risk premium is 6.63%. The Burris Company has a beta of 0.78. Using the capital asset pricing model (CAPM) approach, Burriss cost of equity is . The cost of equity using the bond yield plus risk premium approach The Adams Company is closely held and, therefore, cannot generate reliable inputs with which to use the CAPM method for estimating a companys cost of internal equity. Adamss bonds yield 11.52%, and the firms analysts estimate that the firms risk premium on its stock over its bonds is 3.55%. Based on the bond-yield-plus-risk-premium approach, Adamss cost of internal equity is: 18.84% 16.58% 15.07% 14.32% The cost of equity using the discounted cash flow (or dividend growth) approach Johnson Enterprisess stock is currently selling for $45.56 per share, and the firm expects its per-share dividend to be $1.38 in one year. Analysts project the firms growth rate to be constant at 7.27%. Estimating the cost of equity using the discounted cash flow (or dividend growth) approach, what is Johnsons cost of internal equity? 9.79% 13.91% 10.30% 10.82% Estimating growth rates It is often difficult to estimate the expected future dividend growth rate for use in estimating the cost of existing equity using the DCF or DG approach. In general, there are three available methods to generate such an estimate: Carry forward a historical realized growth rate, and apply it to the future. Locate and apply an expected future growth rate prepared and published by security analysts. Use the retention growth model. Suppose Johnson is currently distributing 55% of its earnings in the form of cash dividends. It has also historically generated an average return on equity (ROE) of 12%. Johnsons estimated growth rate is %.
