Understanding the optimal capital structure Review this situation: Transworld Consortium Corp. is trying to identify its optimal capital structure. Transworld Consortium Corp. has gathered the following financial information to help with the analysis. Debt Ratio Equity Ratio EPS DPS Stock Price 30% 70% 1.25 0.55 36.25 40% 60% 1.40 0.60 37.75 50% 50% 1.60 0.65 39.50 60% 40% 1.85 0.75 38.75 70% 30% 1.75 0.70 38.25 Which capital structure shown in the preceding table is Transworld Consortium Corp.'s optimal capital structure? Debt ratio = 60%; equity ratio = 40% Debt ratio = 30%; equity ratio = 70% Debt ratio = 70%; equity ratio = 30% Debt ratio = 40%, equity ratio = 60% Debt ratio = 50%; equity ratio = 50% Consider this case: Globo-Chem Co. currently has a capital structure consisting of 35% debt and 65% equity. However, Globo-Chem Co.'s CFO has suggested that the firm increase its debt ratio to 50%. The current risk-free rate is 3%, the market risk premium is 7%, and Globo- Chem Co.'s beta is 1.25. If the firm's tax rate is 45%, what will be the beta of an all-equity firm if its operations were exactly the same? Now consider the case of another company: U.S. Robotics Inc. has a current capitarstructure of 30% debt and 70% equity. Its current before-tax cost of debt is 6%, and its tax rate is 45%. It currently has a levered beta of 1.25. The risk-free rate is 3%, and the risk premium on the market is 7%. U.S. Robotics Inc. is considering changing its capital structure to 60% debt and 40% equity. Increasing the firm's level of debt will cause its before-tax cost of debt to increase to 8%. Use the Hamada equation to unlever and relever the beta for the new level of debt. What will the firm's weighted average cost of capital (WACC) be if it makes this change in its capital structure (Hint: Do not round intermediate calculations.) Which of the following statements regarding a firm's optimal capital structure are true? Check all that apply. The optimal capital structure minimizes the firm's cost of debt. a The optimal capital structure maximizes the firm's stock price. The optimal capital structure maximizes the firm's EPS. The optimal capital structure minimizes the firm's WACC. The optimal capital structure minimizes the firm's cost of equity
