Computation of weighted cost of capital.

The Ewing Distribution Company is planning a $100 million expansion of its chain of discount service stations to several neighbouring states. This expansion will be financed, in part, with debt issued with a coupon interest rate of 6.8%. The bonds have a 10-year maturity and a $1,000 face value, and they will be sold to net Ewing $990 per bond. Ewing's marginal tax rate is 40%.

Preferred stock will cost Ewing 7.5% after taxes. Ewing's common stock pays a dividend of $2 per share. The current market price per share is $35. Ewing's dividends are expected to increase at an annual rate of 5% for the foreseeable future. Ewing expects to generate sufficient retained earnings to meet the common equity portion of the funding needed for the expansion.

Ewing's target capital structure is as follows:

Debt = 20%

Preferred stock = 5%

Common equity = 75%
