Omega Corporation has 10 million shares outstanding, now trading at $55 per share.

The firm has estimated the expected rate of return to shareholders at about 12%. It has also issued long-term bonds at an interest rate of 7%. It pays tax at a marginal rate of 35%.

a. What is Omega’s after-tax WACC?

b. How much higher would WACC be if Omega used no debt at all? ( Hint: For this problem you can assume that the firm’s overall beta [  A ] is not affected by its capital structure or the taxes saved because debt interest is tax-deductible.)
