What discount rate should you use to evaluate the warehouse project? a. Calculate component weights of capital. The weight of debt in the firm's capital structure is 31.25 %. (Round to two decimal places.) The weight of preferred stock in the firm's capital structure is 20.54 %. (Round to two decimal places.) The weight of common stock in the firm's capital structure is 48.21%. (Round to two decimal places.) b. Calculate component costs of capital. The after-tax cost of debt for the firm is 4.09 %.
