Hardmon Enterprises is currently an all-equity firm with an expected return of 11.5%. It is considering borrowing money to buy back some of its existing shares. Assume perfect capital markets. a. Suppose Hardmon borrows to the point that its debt-equity ratio is 0.50. With this amount of debt, the debt cost of capital is 5%. What will be the expected return of equity after this transaction? b. Suppose instead Hardmon borrows to the point that its debt-equity ratio is 1.50. With this amount of debt, Hardmon's debt will be much riskier. As a result, the debt cost of capital will be 7%. What will be the expected return of equity in this case? c. A senior manager argues that it is in the best interest of the shareholders to choose the capital structure that leads to the highest expected return for the stock.

Suppose instead Hardmon borrows to the point that its debt-equity ratio is 1.50. With this amount of debt, Hardmon's debt will be much riskier. As a result, the debt cost of capital will be 7%. What will be the expected return of equity in this case? The expected return is%. (Round to two decimal places.) c.

How would you respond to this argument? (Select the best choice below.) OA False, because retums are higher because risk is higher and the return fairly compensates for the risk. OB. True, because the manager's argument is correct. OC. True, because this would also lead to the highest earnings per share. OD. True, because this will result in a higher market value for the stock
