a 7. Pettit Printing Company has a total market value of $100 million, consisting of 1 million shares selling for $50 per share and $50 million of 10% perpetual bonds now selling at par. The company's EBIT is $13.20 million, and its tax rate is 25%. Pettit can change its capital structure by either increasing its debt to 70% (based on market values) or decreasing it to 30%. If it decides to increase its use of leverage, it must call its old bonds and issue new ones with a 12% coupon. If it decides to decrease its leverage, it will call its old bonds and replace them with new 9% coupon bonds. The company will sell or repurchase stock at the new equilibrium price to complete the capital structure change. The firm pays out all earnings as dividends; hence, its stock is a zero growth stock. Its current cost of equity, rs, is 14%. If it increases leverage, rs will be 16%. If it decreases leverage, rs will be 13%. Present situation (50% debt): a. What is the firm's WACC?
