Answer:
WACC = 6.38%
Step-by-step explanation:
Cost of equity = 1.7% + (1.15 x 5.6%) = 8.14%
Weight of equity = 52%
After tax cost of debt = 5.7% x (1 - 35%) = 3.705%
Weight of debt = 40%
Cost of preferred stock = $2.49 / $30 = 8.3%
Weight of preferred stock = 8%
WACC = (8.14% x 0.52) + (3.705% x 0.4) + (8.3% x 0.08) = 6.3788% ≈ 6.38%
