Answer:
the firm's after-tax cost of debt is 4.43 %.
Step-by-step explanation:
Cost of Debt is the return required by providers of debt capital to the company.
First Determine the yield of the Tech Express bonds, r
Pv = - $989
pmt = $1,000 × 6.00 % = $60
p/yr = 1
n = 10
Fv = $1,000
r = ?
Using a Financial Calculator, the yield of the Tech Express bonds, r is 6.1505 %.
Therefore,
Cost of Debt = Interest × ( 1 - tax rate)
= 6.1505 % × ( 1 - 0.28)
= 4.43 %
