Answer:
b. The capital structure that minimizes the firm's weighted average cost of capital is also the capital structure that maximizes its earnings per share.
Step-by-step explanation:
The optimal capital structure is estimated by calculating the mix of debt and equity that minimizes the weighted average cost of capital (WACC) while maximizing its market value. The lower the cost of capital, the greater the present value of the firm’s future cash flows, discounted by the WACC. Thus, the chief goal of any corporate finance department should be to find the optimal capital structure that will result in the lowest WACC and the maximum value of the company (shareholder wealth).
