Calculate the cost of each capital component, that is, the after-tax cost of debt, the cost of preferred stock, the cost of equity from retained earnings, and the cost of newly issued common stock. Use the DCF method to find the cost of common equity.

After-tax cost of debt: fill in the blank 2 %

Cost of preferred stock: fill in the blank 3 %

Cost of retained earnings: fill in the blank 4 %

Cost of new common stock: fill in the blank 5 %

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

fill in the blank 6 %

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.)

fill in the blank 7 %

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: fill in the blank 8 %

WACC₂: fill in the blank 9 %
