Answer:
5.657%
Explanation:
Data provided:
Face value = $1,000
Current market price = $640
Time of maturity, t = 8 year
Now,
the compounding formula is given as:
Face value = Current amount ×
where,
r is the rate i.e pretax rate of debt
n is the number of times the interest is compounded i.e for semiannual n = 2
thus, on substituting the values, we get
$ 1,000= $ 640 ×
or
1.5625 =
or
= 1.0282
or
r = 0.05657
or
pretax cost of debt = 0.05657 × 100% = 5.657%
