It is your job to determine your company's marginal cost of capital schedule. The firm's current capital structure, which it considers optimal, consists of 30% debt, 20% preferred stock, and 50% common equity. The firm has determined that it can borrow up to $15 million in debt at a pre-tax cost of 7%, an additional $9 million at a pre-tax cost of 9%, and any additional debt funds at 11%. The firm expects to retain $25 million of its earnings; any additional income can be raised by issuing new common stock. The firm's common stock currently trades at $30 per share, and it pays a $3.00 per share dividend. Dividends are expected to grow at a 5% annual rate over time. If the firm issues new common stock it will be sold to the public at a 10% discount. There will also be a $2.00 per share flotation cost. Preferred stock can be issued in unlimited quantities at a pre-tax cost of 12%. If the firm decides to raise more than $80m in capital, what is the cost of that capital? Assume a tax rate of 40%. 11.63% O 12.38% 13.18% 14.01%
