Skye's earnings per share last year were $3.40. The common stock sells for $50.00, last year's dividend (D₀) was $2.40, and a flotation cost of 10% would be required to sell new common stock. Security analysts are projecting that the common dividend will grow at an annual rate of 9%. Skye's preferred stock pays a dividend of $3.50 per share, and its preferred stock sells for $35.00 per share. The firm's before-tax cost of debt is 10%, and its marginal tax rate is 25%. The firm's currently outstanding 10% annual coupon rate, long-term debt sells at par value. The market risk premium is 5%, the risk-free rate is 6%, and Skye's beta is 1.216.

Cost of preferred stock:

Cost of retained earnings:

Cost of new common stock:

b: 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 r_e and r_s as determined by the DCF method, and add that differential to the CAPM value for r_s.)

d:

If Skye continues to use the same market-value capital structure, what is the firm's WACC assuming that (1) it uses only retained earnings for equity and (2) if it expands so rapidly that it must issue new common stock? (Hint: Use the market value capital structure excluding current liabilities to determine the weights. Also, use the simple average of the required values obtained under the two methods in calculating WACC.)

WACC₁: %

WACC₂: %
