Answer and Explanation:
In order to make the adjustment for tax for determining the weighted average cost of capital , the debt component should be used as the interest expense is to be considered as deductible due to which the tax impact would be decreased
The after tax cost of debt is
= Cost of debt × (1 - tax rate)
= 9.70% × (1 - 0.25)
= 7.28%
Now the ytm would be
Given that
Future value = $1,000
Present value = $1,555.38
NPER = 15%
PMT = $1,000 ×11% = $110
The formula is given below:
= RATE(NPER;PMT;-PV;FV)
The present value comes in negative
After applying the above formula, the yield to maturity is 5.4759%
Now the after tax cost of debt is
= 5.4759% × (1 - 0.25)
= 4.11%
