Answer:
WACC = 8.41%
Step-by-step explanation:
The weighted Average cost of Capital is the average cost of capital for the different sources of long-term capital available to a firm weighted according to the proportion each source of finance bears to the total capital in the pool..
After-tax cost of debt = (1- tax rate) × before tax cost of debt
= (1-0.23)× 6% = 4.6%
Type Cost (%) Weight cost × weight
Equity 10 70 7
Preferred stock 5 5 0.25
Debt 4.6% 25 1.155
Total 100 8.405
WACC = 8.405 / 100 × 100 = 8.41%
WACC = 8.41%
