Rollins Corporation is estimating its WACC. Its target capital structure is 20 percent debt, 20 percent preferred stock, and 60 percent common equity. Its bonds have a 12 percent coupon, paid semiannually, a current maturity of 20 years, and sell for 1,000 USD. The firm could sell, at par, 100 USD preferred stock which pays a 12 percent annual dividend, but flotation costs of 5 percent would be incurred. Rollins' beta is 1.2, the risk-free rate is 10 percent, and the market risk premium is 5 percent. Rollins is a constant-growth firm which just paid a dividend of $2.00, sells for 27.00 USD per share, and has a growth rate of 8 percent. The firm's marginal tax rate is 40 percent.
