Answer:
7.20%
Step-by-step explanation:
Given that
Coupon rate = 9%
Yield to maturity = 12%
And marginal tax rate is 40%
So by considering the above information, the after tax cost of debts is
= Yield to maturity × (1 - tax rate)
= 12% × (1 - 0.40)
= 7.20%
After considering the tax rate and then multiplying with the yield to maturity we can get the after tax cost of debt
We ignored the coupon rate
