Answer: 5.52%
Step-by-step explanation:
Given the following :
Face value (f) = $1000
Bond price(p) = 96% of face value = 0.96 × 1000 = $960
Coupon rate = 5% Semi-annually = 0.05/2 = 0.025
Payment per period (C) = 0.025 × 1000 = $25
Period(n) = 10 years = 10 × 2 = 20
Semiannual Yield to maturity = [(((f-p)/n) + C) / (f + p)/2]
Semiannual YTM = [(((1000 - 960) / 20) + 25) / (1000 + 960)/2]
Semiannual Yield to maturity = [(((40 /20) + 25) / 1960/2]
= (2 + 25) / 980
= 27 / 980 = 0.02755 = 2.755% = 2.76%
Pretax cost of debt = Yield to maturity = 2 × Semiannual yield to maturity
Pretax cost of debt = 2 × 2.76% = 5.52%
