Answer:
10.72%
Step-by-step explanation:
WACC = (weight of equity x cost of equity) + [weight of debt x cost of debt x (1 - tax rate)] +( weight of preferred stock x cost of preferred stock)
debt = 0.41 x 12% x (1 - 0.4) = 2.95%
preferred stock = 0.05 x 12.98% = 0.65%
common equity = 0.54 x 13.18% = 7.12%
WACC = 2.95% + 0.65% + 7.12% = 10.72%
