Answer:
5.71%
Step-by-step explanation:
The after tax cost of debt=pretax cost of debt*(1-t)
where t is the tax rate of 35% or 0.35
pretax cost of debt=yield to maturity
The yield to maturity can be determined using rate formula in excel as below:
=rate(nper,pmt,-pv,fv)
nper is the number of coupon interest payable by the bonds i.e 12 coupons in 12 years
pmt is the annual coupon=$1000*9.5%=$95
pv is the current market price-flotation cost=$1,100-$48=$1052
fv is the face value of $1000
=rate(12,95,-1052,1000)=8.78%
After tax cost of debt=8.78% *(1-0.35)=5.71%
