Answer:
10.5%
Step-by-step explanation:
Holmes company currently have an outstanding bond of 9% coupon
They also have a 14% yield to maturity
= 14/100
= 0.14
The marginal tax rate is 25%
= 25/100
= 0.25
The after-tax cost of debt can be calculated as follows
After tax-cost of debt= Yield to maturity × (1-tax rate)
= 0.14× (1-0.25)
= 0.14×0.75
= 0.105×100
= 10.5%
Hence the after-tax cost of debt for Holmes company is 10.5%
