Answer:
WACC is 7.24%
After tax cost of debt is 3.95%
Explanation:
WACC=Ke*E/V+Kd*D/V*(1-t)+Kp*P/V
Ke is the cost of equity of 9% or 0.09
Kd is the cost of debt at 5% or 0.05
Kp is the of preferred stock of 4% or 0.04
E is the weight of equity of 65% 0r 0.65
D is the weight of debt of 25% 0.25
K is the weight of preferred stock of 10% or 0.10
t is the tax rate of 21% or 0.21
WACC=(0.09*0.65)+(0.05*0.25*1-0.21)+(0.04*0.10)
WACC=(0.09*0.65)+(0.05*0.25*0.79)+(0.04*0.10)
WACC=7.24%
after tax cost of debt=pretax cost of debt*(1-t)
=0.05*(1-0.21)
=0.0395=3.95%
