Problem3 Consider three hypothetical securities X.Y and Z, whose cash flows are given by the following table. Year Security X Security Y Security Z Here the cash flows are assumed to occur at the end of each year The spot rate curve is as follows: Year $10 $110 $60 $110 $10 $60 Spot rates 5.571% 6.088% Assume a yearly compounding convention. (a) Compute the present values of these three securities using the spot rate curve. (b) Compute the yields to maturity of three securities using the result obtained in (a). (c) Securities X. Y and Z have the same term to maturity (2 years). Do they have the same yield? If not, what is the reason for the difference
