Q7. Rоss аnd Sоns Inc. hаs а target capital structure that calls fоr 40 percent debt and 60 percent common equity. The company’s only interest bearing debt is 10 year bond. The company’s 10 year long-term bonds pay 8% semiannual coupon (that is, 4% of the principal will be paid every six months) and the bonds are currently sold at $1,200 and the par of the bond is $1,000. The firm can issue bonds only $100 million at this price. Beyond this amount, the firm can issue the bonds at the same price, but the firm has to pay 10% semiannual coupon. Ross expects to have $300 million earnings and to retain 80% of earnings. Ross' common stock currently sells for $30 per share, but if the firm issues new common stock the firm has to pay 10% flotation costs. The firm paid the most recent dividend of $2 (D0=$2.00) per share on its common stock, and investors expect the dividend to grow indefinitely at a constant rate of 6 percent per year. The firm’s tax rate is 40%. The company has a very lucrative new project and the project requires $350 million. What is cost of debt (rd or rd')? (Pick the closest answer.)
