Calculation of individual costs and WACCLang Enterprises is interested in measuring its overall cost of capital. Current investigation has gathered the following data. The firm is in the 30% tax bracket.

DebtThe firm can raise debt by selling $1,000-par-value, 9% coupon interest rate,

10-year bonds on which annual interest payments will be made. To sell theissue, an average discount of $25

per bond would have to be given. The firm also must pay flotation costs of $35 per bond.

Preferred stockThe firm can sell 6% preferred stock at its $90-per-share

par value. The cost of issuing and selling the preferred stock is expected to be $7 per share. Preferred stock can be sold under these terms.

Common stockThe firm's common stock is currently selling for

$60 per share. The firm expects to pay cash dividends of $5

per share next year. The firm's dividends have been growing at an annual rate of 68%,

and this growth is expected to continue into the future. To sell new shares of common stock, the firm must underprice the stock by

$7 per share, and flotation costs are expected to amount to $3

per share. The firm can sell new common stock under these terms.

$140,000

of retained earnings in the coming year; once these retained earnings are exhausted, the firm will use new common stock as the form of common stock equity financing.
