calculating the WACC.

Here is the condensed 2008 balance sheet for Skye Computer Company (in thousands of dollars):

2008

Current Assets\$2,000Current Liability\$900

Net fixed assets \$3,000Long- term debt\$1,200

Total assets\$5,000 Preperred stock\$250

Common stock\$1,300

Retained earnings\$1,350

Totalcommon equity \$2,650

Totalliability &equity\$5,000

Skye's earnings per share last year were \$3.20, the common stock sells for \$55.00, last year's dividend was \$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 a rate of 9% per year. Skye's preferred stockpays a dividend of \$3.30 per share, and new preferred could be sold at a price to net the company \$30.00 per share. The firm can issue long-term debt at aninterest rate (or before-tax cost) of 10%, and its marginal tax rate is 35%. The market risk premium is 5%, the risk-free rate is 6%, and Skye's beta is 1.516. Inits cost of capital calculations, the company considers only long-term capital; hence, it disregards current liabilities.

a)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, andthe cost of newly issued common stock. Use the DCF method to find the cost of common equity.

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 andadd that differential to the CAPM value for rs.)

d) If Skye continues to use the same capital structure, what is the firm's WACC assuming that (1) it uses only retained earnings for equity ? (2) If it expands sorapidly that it must issue new common stock ?
