Answer:
See explaination
Step-by-step explanation:
cost of debt, after-tax = (4.3% + 1.2%)*(1 - 26%) = 4.07%
cost of equity = 4.3% + 1.3*4% = 9.5%
market capitalization = 286130000 * 182 = 52075660000
total value of equity outstanding = market capitalization = 52075660000
Debt portion = 11532000000 / (11532000000 + 52075660000) = 0.18
Equity portion = 1 - 0.18 = 0.82
weighted average cost of capital = 0.18*4.07% + 0.82*9.5% = 8.52%
