Explanation:
In order to determine the after-tax cost of debt we need to determine first of all the pretax cost of debt which is the yield to maturity on the bond computed using rate formula in excel.
=rate(nper,pmt,-pv,fv)
nper is the number of coupon interest payable over twenty years which is 20 years *2=40
pmt is the semiannual interest payment=$1000*7.25%*6/12=$36.25
pv is the current price of $875
fv is the face value of $1000
=rate(40,36.25,-875,1000)=4.28%
annual yield =4.28%*2=8.56%
after tax cost of debt=8.56%*(1-40%)=5.14%
cost of equity=risk free rate(20-year treasury rate)+Beta*(Return on stock market-risk free rate)
cost of equity=5.50%+1.25*(11.5%-5.5%)=13%
Market value of equity=$15.25*10,000,000=$152,500,000.00
Market value of bonds=$875*40,000=$35,000,000.00
Equity plus debt =$ 187,500,000
weighting of debt=$35,000,000/$187,500,000= 0.19
weighting o equity= $152,500,000.00/$187,500,000.00 = 0.81
WACC=Ke*We+Kd(after tax)*Wd=13%*0.81+5.14%*0.19=11.51%
