Rollins Corporation is estimating its WACC. Its target capital structure is 20% debt, 20% preferred stock, and 60% common equity. Its bonds have a 7.5% coupon, paid semi-annually, a current maturity of 20 years, and sell for $1,105.78. The firm could sell, at par, $100 preferred stock which pays a 8% annual dividend, but flotation costs of 5 percent would be incurred. Rollins' beta is 1.8, the risk-free rate is 2.45%, and the market risk premium is 5%. The firm's marginal tax rate is 40 percent. A. What is the companyâs cost of preferred equity?

C. What is the company's WACC?

Explanation:

20% debt ⇒ after tax cost of debt 3.76%

20% preferred stock ⇒ 8.42%

60% common equity ⇒ 11.45%

in order to determine the after tax cost of debt we must first determine the yield to maturity of debt:

approximate YTM = {37.5 +[(1,000 - 1,150.78)/40]} / [(1,000 + 1,150.78)/2] = 33.7305 / 1,075.39 = 3.3166% x 2 = 6.2732%

after tax cost of debt = 6.2732% x 0.6 = 3.76%

cost of preferred stocks = 8 / (100 x 0.95) = 8 / 95 = 8.42%

cost of equity (Re) = 2.45% + (1.8 x 5%) = 2.45% + 9% = 11.45%

WACC = (60% x 11.45%) + (20% x 8.42%) + (20% x 3.76%) = 6.87% + 1.684% + 0.752% = 9.306% = 9.31%

im confused need to go into details plz thx
