Answer:
a. 7.30%
b. 4.745%
Explanation:
For computing the pretax cost of debt we have to applied the RATE formula i.e to be shown in the attachment below:
Given that,
Present value = $1,000 × 106% = $1,060
Assuming figure - Future value or Face value = $1,000
PMT = 1,000 × 8% ÷ 2 = $40
NPER = 14 years × 2 = 28 years
The formula is shown below:
= Rate(NPER;PMT;-PV;FV;type)
The present value come in negative
So, after applying the above formula
a. The pretax cost of debt is
= 3.65% × 2
= 7.30%
b. And, the after tax cost of debt would be
= Pretax cost of debt × ( 1 - tax rate)
= 7.30 % × ( 1 - 0.35)
= 4.745%
