Answer:
After tax cost of debt is 4.16%
Explanation:
The yield on the debt which is pre-tax cost of debt can be computed using the rate formula in excel, which is given as follows:
=rate(nper,pmt,-pv,fv)
where nper is the number of coupon payments,this is calculated as 19*2 since it has a semi-annual coupon interest
pmt is the periodic coupon payment 6.1%/2*$2000=$61
pv is the current price of the bond which is $1933
fv is the face value repayable on redemption $2000
=rate(38,61,-1933,2000)
=3.20%
This is semi-annual yield , annual yield is 3.20%*2=6.40%
After tax cost of debt=6.40%*(1-t)
where t is the tax rate at 35%=0.35
after tax cost of debt=6.40%*(1-0.35)
=4.16%
