J. Ross and Sons Inc. has a target capital structure that requires 50 percent debt and 50 percent common equity. The company's only interest-bearing debt is a 10-year bond. The company's 10-year long-term bonds pay a semi-annual coupon of 8% (that is, 4% of the principal will be paid every six months) and the bonds are currently selling for $1,200 and the bond par is $1,000. The company can issue bonds for only $10 million at this price. Beyond this amount, the company can issue the bond at the same price, but the company has to pay a semi-annual coupon of 9% (ie, 4.5% of the principal will be paid every six months). Ross expects retained earnings of $15 million. Ross common shares currently sell for $30 per share, but if the company issues new common shares, the company has to pay 10% of the floatation costs. The company will pay an upcoming dividend of $2 (D ₁ = $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 business tax rate is 30%.

The company has a very lucrative new project and it requires $35 million. What should the WACC be for this project? To answer the question, you need to calculate debt break points and retained earnings.
