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 5 percent coupon, paid semiannually, a current maturity of 12 years, and sell for $876.34.

The firm plans to sell preferred stock at $95 with $10 annual dividend, but flotation costs of 5 percent would be incurred. Rollins' beta is 1.5, the risk-free rate is 5 percent, and the market risk premium is 6 percent. Rollins is a constant-growth firm which just paid a dividend of $25.00 and has a growth rate of 8 percent. Flotation cost of 6 percent would be included for issuing additional shares of common stocks.

The firm's policy is to use a risk premium of 6 percentage points when using the bond-yield-plus-risk-premium method to find the cost of equity. The firm's marginal tax rate is 40 percent.
