Answer and Explanation:
The computation is shown below:
a. Pre tax cost of debt is
Given that
NPER = 30 - 7 = 23 × 2= 46
PMT =$1,000 × 6.2% ÷ 2 = $31
FV = $1,000
PV = $1000 × 108% = $1,080
The formula is shown below:
= RATE(NPER,PMT,-PV,FV,TYPE) × 2
AFter applying the above formula, the rate is 5.58%
b. The after tax cost of debt is
= 5.58% × (1 - 0.35)
= 3.63%
c. The after tax cost of debt would be considered more relevant
