Answer:
12.085 %
Step-by-step explanation:
WACC = Cost of Equity x Weight of Equity + Cost of Preference Stock x Weight of Preference Stock + Cost of Debt x Weight of Debt
Remember to use the after tax cost of debt :
after tax cost of debt = interest x ( 1 - tax rate)
= 8.00 % x (1 - 0.35)
= 5.20 %
therefore,
WACC = 22.00 % x 0.40 + 8.50 % x 0.05 + 5.20 % x 0.55
= 12.085 %
thus
the firm's WACC given a tax rate of 35 percent is 12.085 %
