Answer:
D) 12.9%
Explanation:
WACC formula;
WACC = wE*rE + wD*rD(1-tax)
whereby,
wE = weight of equity = 2/3 or 66.67%
rE = cost of equity = 16%
wD = weight of debt = 1/3 or 33.33%
rD = pretax cost of debt = 9%
WACC = (0.6667*0.16 ) + [0.3333*0.09(1-0.35) ]
= 0.1067 + 0.0195
= 0.1262 or 12.62%
Therefore, the after-tax WACC will be closest to 12.9%
