Lang Enterprises is interested in measuring its overall cost of capital. Current investigation has gathered the following data. The firm is in the 40% tax bracket.
Debt. The firm can raise an unlimited amount of debt by selling $1,000-par-value, 8 % coupon interest rate, 20-year bonds on which annual interest payments will be made. To sell the issue, an average discount of $30 per bond would have to be given. The firm also must pay flotation costs of $30 per bond.
Preferred stock. The firm can sell 8% preferred stock at its $95-per-share par value.
The cost of issuing and selling the preferred stock is expected to be $5 per share.
An unlimited amount of preferred stock can be sold under these terms.
Common stock. The firm's common stock is currently selling for $90 per share. The firm expects to pay cash dividends of $7 per share next year. The firm's dividends have been growing at an annual rate of 6%, and this growth is expected to continue into the future. The stock must be underpriced by $7 per share, and flotation costs are expected to amount to $5 per share. The firm can sell an unlimited amount of new common stock under these terms.
Retained earnings. When measuring this cost, the firm does not concern itself with the tax bracket or brokerage fees of owners. It expects to have available $100,000 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.

a. Calculate the specific cost of each source of financing. (Round answers to the nearest 0.1%.)

b. The firm's capital structure weights used in calculating its weighted average cost of capital are shown in the following table. (Round answer to the nearest 0.1%.)

Source of Capital Weight

Long-term debt .......... 30%

Preferred stock ........... 20

Common stock equity ........ 50

Total ............... 100%

(1) Calculate the single break point associated with the firm's financial situation. (This point results from exhaustion of the firm's retained earnings,)

(2) Calculate the weighted average cost of capital associated with total new financing below the break point calculated in part (1).

(3) Calculate the weighted average cost of capital associated with total new financing above the break point calculated in part (1)
