Here is the condensed 2015 balance sheet for Skye Computer Company (in thousands of dollars): Skye's earnings per share last year were dollar 3.20. The common stock sells for dollar 55.00, last year's dividend (D_0) was dollar 2.10, 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 percentage. Skye's preferred stock pays a dividend of dollar 3.30 per share, and its preferred stock sells for dollar 30.00 per share. The firm's before-tax cost of debt is 10 percentage, and its marginal tax rate is 35 percentage. The firm's currently outstanding 10 percentage annual coupon rate, long-term debt sells at par value. The market risk premium is 5 percentage, the risk-free rate is 6 percentage, and Skye's beta is 1.516. The firm's total debt, which is the sum of the company's short-term debt and long-term debt, equals dollar 1.2 million. 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. Now calculate the cost of common equity from retained earnings, using the CAPM method. What is the cost of new common stock based on the CAPM? 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? (2) If it expands so rapidly that it must issue new common stock
