Consider a 3-year, 4.5% annual coupon bond represented by the binomial interest rate tree on the following page. The bond is callable at par starting at the end of year 1. The one-year benchmark implied forward rates are provided for one node of each year of the bond. The bonds OAS is 40 basis points. Assume that the interest rate volatility = 10%. Please complete the tree, filling in the interest rates and the value of the bond at each node (wherever a ???? occurs, fill in an answer). Remember to adjust the benchmark rates with the OAS after all of the benchmark rates in the tree have been determined. Note that each node except the one at time=0 represents the payment of a 4.5% coupon, so be sure to include that in the valuation.
