Answer:
Before tax cost of debt = 10.84%
After tax cost of debt = 6.72%
Explanation:
given data
coupon rate = 10%
Maturity value = $1,000
time = 10 year = 40 Quarter
currently sells price = $950
tax rate = 40 percent
solution
we get here first Quarterly Coupon Payment that is
Quarterly Coupon Payment = 10% × 1,000 × [tex]\frac{1}{4}[/tex]
Quarterly Coupon Payment = $25
and
here Cost of Debt is Annual YTM so we get here rate r as Quarterly YTM
so
950 = 25 × PVIFA(r%, 40) + 1,000 × PVFA(r%, 40)
solve we get
rate r = 2.71 %
so Annual YTM is
Annual YTM = 4 × 2.71%
Annual YTM = 10.84%
so
Before tax cost of debt = 10.84%
and
After tax cost of debt = 10.84% × (1-0.38)
After tax cost of debt = 6.72%
