A. Determine the future periodicspot interest rates, at one periodfrom now, on a onestep HoLee model, using current periodic spot interest rate of A1 percent, current spot rate over two periodsof A2 percent, and an annual interest rate volatility of .005 (.5%). Then consider the current spot rate over three periodsof A3 percent to find the future periodicinterest rates in a twostep HoLee model. The period is A4 months. Find the following.
1. The trend (lambda1) ininterest rate in the first period.
2. The trend (lambda2) in interest rate in the second period.
3. The future periodic rate on the upside at the end of one period.
4. The future periodic rate on the downside at the end of one period.
5. The future periodic rate at the upmost branch at the end of two periods.

D.Consider D1month spot interest rates evolving in the following threestep binomial tree over D4 months, i.e., with D1 months in each of the next three steps. The current D3month spot interest rate is 5.15%, the current D2month spot interest rate is 5.3%, and the current D4month spot interest rate is 5.45%. This threestep problem involves calculation of just the third step, because it is an extension of the twostep Problem C. Find the following by assuming monthly compounding.

E. Suppose that you are long in an original portfolio of 20year bonds with a total face value of E1 million dollars and that you want to hedge the portfolio value against fluctuating interest rates by trading on a 10year bond and a 30year bond. You have estimated (given): DV0110 = E2, DV0120 = E3, and DV0130 = E4 per $100 face value of 10year, 20year and 30year bonds, respectively. You have also used yield data on these bonds to estimate the coefficients, b=1.3 and c = 1.6, inthe following regression:
Δy_{t}^{20} = a + bΔy_{t}^{10} + cΔy_{t}^{30} + ε
Using the given data, determine your optimal trading strategy for the 10year and 30year bonds to hedge 20year bonds. Report answers for the following:
19. Face value in dollars of 10 year bonds needed for hedging.
20. Face value in dollars of 30 year bonds needed for hedging.
After hedging, suppose that you observe that the 20year yield moves by E5 basis points when the 10year yield moves by 1 basis point and that the 20year yield moves by E6 basis points when the 30year yield moves 1 basis point. Then:
21. How much will be your profit or loss corresponding to 30year yield increasing by 1 basis point?
F. A collared floater is like a variable rate bond, but with an upper limit and a lower limit on the rate of coupon payment. Consider, for example, annual rates coupon payment and oneyear spot interest rates. In the following table, the current oneyear spot interest rate is denoted by rin column (1). Depending on the current spot interest rate, the collared floater with a face value of F1 dollars will pay the holder of this floater a sum a year later, as given in column (2) of the table. The binomial tree below gives the evolution of oneyear spot interest rates over a four year period.
22. What is the current fair value of the fouryear collared floater if the riskneutral probabilities in the binomial tree are 0.5 and 0.5 for the up and down moves, respectively?

G. A fouryear participating cap pays an interest based on a nominal principal of G1, at the end of the year if the current annual spot interest rate, r, is higher than 5%. If the current annual spot rate, r, is less than 5%, the participating cap obligates its holder to lose 30% of (5%r%) on the nominal principal at the end of the year. The payments are given in column (2) of the following table, given the rates in column (1). The binomial tree below gives the evolution of oneyear spot interest rates over a four year period.
23. What is the current fair value of the participating cap if the riskneutral probabilities in the binomial tree are 0.5 and 0.5 for up and down moves, respectively?

H. What is the risk premium (spread) of a H1 percent annual coupon, 3.35 year maturity, and 100face value bond? The bond pays the annual coupon in two equal installmentsand trades now at a quoted spot price of H2. Assume continuous compounding and use the term structure of discount factors for riskless bonds, d(t) = 1  .03t  .0075t2 + .0015t3. Report answer for the following (Hint: rate at which to discount future cash flows of a risky bond to find the current value is (as per CAPM) the riskless rate which changes with the term of the cash flow plus risk premium which is fixed across all terms; the easier way to solve for risk spread by the method of trial and error, as done an equation solver):
