Capital Co. has a capital structure, based on current market values, that consists of 34 percent debt, 12 percent preferred stock, and 54 percent common stock. If the returns required by investors are 8 percent, 13 percent, and 16 percent for the debt, preferred stock, and common stock, respectively, what is Capital's after-tax WACC?
