Answer:
d. 2.94%
Explanation:
First, Calculate the Yield to maturity of the bond using the following formula
Use the following formula to calculate the YTM
P = [ C x ( 1 - ( 1 + r )^-n ) / r ] + [ F / ( 1 + r )^n ]
Where
F = Face value = $1,000
P = Price = $1,495.56
C = Coupon payment = Face value x Coupon rate = $1,000 x 10% = $100
n = numbers of periods = Numbers of years to maturity = 10 years
r = YTM = ?
Placing values in the formula
$1,495.56 = [ $100 x ( 1 - ( 1 + r )^-10 ) / r ] + [ $1,000 / ( 1 + r )^10 ]
r = 3.916%
Now calculate the after-tax cost of debt
After-tax cost of debt = YTM x ( 1 - Tax rate )
After-tax cost of debt = 3.916% x ( 1 - 25% )
After-tax cost of debt = 2.937%
After-tax cost of debt = 2.94%
