Answer:
C) 5.63%
Explanation:
First we have to find the pretax cost of debt of the firm in order to find it's after tax cost of debt.
We know the price of the bond is $102.3, its future value or par value is $100, the number of periods are 11 as it is annual coupon bond with a maturity of 11 years and the coupon payment each year is (0.09*100)= $9. We can input these values in a financial calculator to find the bonds ytm or cost of debt.
PV= 102.3
FV= -100
PMT=-9
N= 11
Compute I = 8.66
The pretax cost of debt is 8.66%
Now in order to calculate the after tax cost of debt we will use the formula
Pretax cost of debt *(1-tax rate)
=0.0866*(1-0.35)=0.05629= 5.629% rounded of to 5.63%
