Omega Corporation has 11.0 million shares outstanding, now trading at $65 per share. The firm has estimated the expected rate of return to shareholders at about 11%. It has also issued long-term bonds at an interest rate of 7%. It pays tax at a marginal rate of 40%. Assume a $250 million debt issuance. What is Omegas after-tax WACC? How much higher would WACC be if Omega used no debt at all? (Hint: For this problem you can assume that the firms overall beta [A] is not affected by its capital structure or by the taxes saved because debt interest is tax-deductible.)
