Globex Corp. is an all-equity firm, and it has a beta of 1. It is considering changing its capital structure to 65% equity and 35% debt. The firm's cost of debt will be 6%, and it will face a tax rate of 40%. What will Globex Corp.'s beta be if it decides to make this change in its capital structure? Now consider the case of another company: U.S. Robotics Inc. has a current capital structure of 30% debt and 70% equity. Its current before-tax cost of debt is 6%, and its tax rate is 40%. It currently has a levered beta of 1.10. The risk-free rate is 3%, and the risk premium on the market is 8%. 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.) The optimal capital structure is the one that minimizes the WACC and minimizes the firm's stock price. Higher debt levels the firm's risk. Consequently, higher levels of debt cause the firm's cost of equity to For 1st blank options are 1.52. 1.32. 1.25. 1.78 For 2nd blank 7.5%. 6.1%. 9.4%. 10.3% For 3rd blank.
