The weights in the calculation of WACC should be based on the firm’s target capital structure, that is, the proportions (based on market values) of debt, preferred stock, and equity that the firm expects to achieve over time. Book values should not be used. As such, the weight of debt is 41% ($10.5 ÷ $25.7), the weight of preferred stock is 6% ($1.5 ÷ $25.7) and the weight of common stock is 53% ($13.7 ÷ $25.7).
