1. Estimate the bond value The coupons will be $50 in years 1, 2, 3 and 4. Then, on year 5, the bond will pay coupon and principal, for a total of $1050. Discounting to present value at 6.5%, the bond value is $937.66. The detail is the following: Year 1: $50 / (1 + 6.5%) ^ 1 = 46.95 Year 2: $50 / (1 + 6.5%) ^ 2 = 44.08
