Hardmon Enterprises is currently an all-equity firm with an expected return of 18%. It is considering a leveraged recapitalization in which it would borrow and repurchase: 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 6%. What will the expected return of equity be 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 8%. What will the expected roturn of equity be in this case? c.

How would you respond to this argument? 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 6%. What will the expecied return of equity be after this transaction? If Hardmon borrows to the point that its debt-equity ratio is 0.50 and the debt cost of capital is 6%, the expected return is %. (Round to one decimal place.)
