Answer:
YTM is 7.85%
Explanation:
Given that,
Coupon rate = 8.9%
Years = 20 years - 2 years = 18 years × 2 = 36 years
Par value or future value= $1,000
Present value = $1,000 × 110% = $1,100
Monthly payment or PMT = (8.9% × $1,000) ÷ 2 = 44.5
In semi annual payments, we multiply by 2 in years and divide by 2 in PMT as in case of YMT
So, YMT = Rate × 2 = 3.93% × 2 = 7.85%
