a. Calculate the cost of each capital component, that is, the after-tax cost of debt

(rd(1 T)), the cost of preferred stock (rp), the cost of equity from retained earnings (rs),

and the cost of newly issued common stock(re). Use the Discounted Cash Flow (DCF)

method to find the cost of common equity, e.g. rs and re.

b. Now calculate the cost of common equity from retained earnings, using the

CAPM method.

C. What is the cost of new common stock based on the CAPM? (Hint: Find the

difference between re and rs as determined by the DCF method and add that differential to

the CAPM value for rs.)

d. If Skye continues to use the same market-value capital structure, (1) what is

the firms WACC assuming that it uses only retained earnings for equity? (2) what is the

firms WACC assuming that if it expands so rapidly that it must issue new common

stock? (Hint: use current value of stocks to obtain the market-value capital structure, the

weights of capital.)
