Answer:
Explanation:
The pretax cost of debt is the annual interest rate of the bond, also known as the YTM.
Using a financial calculator, input the following;
Maturity of the bond; 12*2 = 24 semiannual payments
Face value; FV = 1,000
Price of the bond; PV = - ( 1.03*1000) = -1,030
Recurring coupon payments; PMT = (7%/2) *1000 = 35
Then compute Semiannual interest rate; CPT I/Y = 3.317%
Next, convert to annual rate (YTM) = 3.317*2 = 6.63%
Aftertax cost of debt is the adjusted YTM after taxes. Since interests paid on debt have tax shield, the aftertax cost of debt will be lower than the pretax cost of debt.
Aftertax cost of debt = Pretax cost of debt (1-tax)
= 6.63%(1-0.33)
= 4.44%
