Answer:
8.1%
Explanation:
Firstly, let look at the formula for calculating weighted average cost of capital (WACC):
WACC = (D/A) x r_D x (1-t) + (E/A) x r_E + (PE/A) x r_PE, where:
A: Market value of company asset;
D: Market value of company debt;
E: Market value of company equity;
PE: Market value of company preferred equity;
r_D: cost of debt;
r_E: cost of equity/retained earnings;
r_PE: cost of preferred equity;
t: tax rate
Putting all the numbers together, we have:
WACC = 35% x 6.5% x (1-25%) + 55% x 10.5% + 10% x 6% = 8.1%
