Answer:
before taxes 5.23%
after tax: 3.40%
Step-by-step explanation:
The bonds coupon interest rate is not the market rate . If Drogo Inc tries to take debt in the market it will be at a different rate as it is not selling at par.
We should determinate the market rate of the bond.
The bond sales as 97% which means the present value of the coupon payment and maturity discounted at the market rate equal 97% of the face value
We solve for this using excel and get:
Present value of the coupon payments
C 25 (1,000 x 5% / 2 payment per year)
time 46 (23 years x 2 payment)
rate 0.026128
PV $664.7027
Present value
Maturity 1,000.00
time 46.00
rate 0.026128
PV 305.30
PV coupon $664.7027 + PV maturity $305.2973 = $970.0000
We know have to multiply this rate by 2 as it is semiannual like the payment:
0.026128 * 2 = 0.0523 = 5.23%
Last we calcualte the after tax cost of debt:
0.0523 (1 - 0.35) = 0.033995 = 3.40%
