Also, to calculate the after-tax cost of debt, please assume our company has total business interest expense less than 30% of adjusted taxable income. You may use the formula: AT k_d = BT k_d * (1 - ISTR).

PART 1 A - COMPUTING A WEIGHTED AVERAGE COST OF CAPITAL (WACC) A firm has determined its optimal capital structure, which is composed of following sources and target market value proportions: Source of Capital Long-term debt Preferred stock Common stock equity Target Market Proportions 60% 5% 35% Debt: The firm can sell a 15 year bond, compounded monthly, with a $1000 par value and 6.8% coupon rate for $1254. A flotation cost of 1.15% of the face value would also be required. Preferred Stock: The firm has determined that it can issue preferred stock at $125 per share par value. The preferred stock wil pay a $6.75 per share annual dividend. The cost of issuing and selling the preferred will be $3.28 per share.
