Answer:
If its marginal tax rate is 25%, Holmes' after-tax cost of debt is 8.25%
Step-by-step explanation:
In order to calculate Holmes' after-tax cost of debt If its marginal tax rate is 25% we would have to calculate the following formula:
After-tax cost of debt =yield to maturity*(1-marginal tax rate)
According to the given data we have the following:
yield to maturity=11%
marginal tax rate=25%
Therefore, After-tax cost of debt =11%*(1-0.25)
After-tax cost of debt =8.25%
If its marginal tax rate is 25%, Holmes' after-tax cost of debt is 8.25%
