Answer :
Answer:
A is the correct option ,5.08%
Explanation:
The component cost of debt used in WACC computation is the after tax cost of debt,which is given as :
after tax cost of debt=pretax cost of debt*(1-t)
t is the tax rate of 40%
Pretax cost of debt can be computed using the rate formula in excel:
=rate(nper,pmt,-pv,fv)
nper is number of coupon payments expected from the bond in the remaining 20 years i.e 20*2=40
pmt is the semiannual coupon payment of $46.25 ($1000*9.25%*6/12)
pv is the current bond price of $1075
fv is the face value of $1,000
=rate(40,46.25,-1075,1000)=4.23%
semiannual rate is 4.23%
annual rate =4.23% *2=8.46%
after tax cost of debt=8.46%*(1-40%)=5.08%
