Company is trying to determine its optimal capital structure. The firm is currently all-equity financed and has a total market value of $10 million. Company plans to keep the toal value of capital the same by using the proceeds from debt financing to repurchase outstanding shares of stock. The firm is in the 40% tax bracket.
