V = B + S The Capital-Structure Question There are really two important questions: Why should the stockholders care about maximizing firm value? Perhaps they should be interested in strategies that maximize shareholder value. What is the ratio of debt-to-equity that maximizes the shareholder’s value? As it turns out, changes in capital structure benefit the stockholders if and only if the value of the firm increases.
