Coleman Technologies is considering a major expansion program that has been proposed by the company's information technology group. Before proceeding with the expansion, the company must estimate its cost of capital. Suppose you are an assistant to Jerry Lehman, the financial vice president. Your first task is to estimate Coleman's cost of capital. Lehman has provided you with the following data, which he believes may be relevant to your task. The firm's tax rate is 40%. The current price of Coleman's 12% coupon, semiannual payment, non-callable bonds with 15 years remaining to maturity, is $1,153.72. Coleman does not use short-term, interest-bearing debt on a permanent basis. New bonds would be privately placed with o flotation cost. The current price of the firm's 10%,$100.00 par value, quarterly dividend, perpetual preferred stock is $111.10. Coleman's common stock is currently selling for $50.00 per share. Its last dividend (D0) was $4.19, and dividends are expected to grow at a constant annual rate of 5% in the foreseeable future. Coleman's beta is 1.2 , the yield on T-bonds is 7%, and the market risk premium is estimated to be 6%. For the bond-yield-plus-risk-premium approach, the firm uses a risk premium of 4%. Coleman's target capital structure is 30% debt, 10% preferred stock, and 60% common equity. To structure the task somewhat, Lehman has asked you to answer the following questions: a. 1. What sources of capital should be included when you estimate Coleman's WACC? 2. Should the component costs be figured on a before-tax or an after-tax basis? b. What is the market interest rate on Coleman's debt and its component cost of debt? c. What is the firm's cost of preferred stock? d. 1. Why is there a cost associated with retained earnings
