Answer:
8.53%
Explanation:
Par value = $1000
Current bond = $922
Coupon = 1000*11.4% = $114
Years = 16
Pretax cost of debt = YTM(Nper, PMT, -PV, FV)
Pretax cost of debt = YTM(16, 114, -922, 1000)
Pretax cost of debt = 0.1255
Pretax cost of debt = 12.55%
After tax cost of debt = Pretax cost of debt * (1 - Tax rate)
After tax cost of debt = 12.55% * (1 - 32%)
After tax cost of debt = 0.1255 * 0.68
After tax cost of debt = 0.08534
After tax cost of debt = 8.53%
