### 1.A 25 year annual coupon bond with face and redemption amount of 2000 is sellingat an e↵ective annual yield rate equal to twice of the annual coupon rate.  数学和统计代考

The present value of the redemption amount is equal to the present value of the coupons.

(a)Determinethe purchase price of the bond at issuance.

(b)Determinethe amount for amortization of premium (or the principal repaid) in the 20th coupon.

(c)Suppose the bond was issued January 15, 2010, and is bought by a new purchaser on January 15, 2020 immediately after the coupon payment for a price of 1500. Find the internal rate of return earned by the original bondholder.

### 2.Attime 0, the term structure of e↵ective annual yield rates for zero coupon bonds is given as follows:  数学和统计代考

1- and 2-year maturity: 8%

3- and 4-year maturity: 10%

(a)Determine the price of a 4-year annual coupon bond with face amount 100 and coupon rate6%.  数学和统计代考

(b)You are given that the price of a 5-year annual coupon bond with face amount 100 and coupon rate 6% is 80. Determine the forward e↵ective annual interest rate for the period from time 4 to time 5,e., f [4, 5].

(c)A lender o↵ers to lend you 1000 for one year at rate 12% starting twoyear from now. Construct transactions that provide an arbitrage gain and give the amount of the gain.

### 3.Liability payments of 100 each are due to be paid in 2, 5 and 8 years from now.

Asset cashflow consists of A3in 3 years and A6 in 6 years. The yield for all payments is 10%. An attempt is made to have the asset cash flow immunize the liability cashflow by matching present value and duration.

(a)Determine the Macaulay duration and the Macaulay convexity of the liabil- ity  cashflflow.  数学和统计代考

(b)Determine A3and A6.

(c)Determine whether or not the conditions for Redington immunization are satisfied.

### 4.Theterm structure of (annual effective) interest rates is as follows:  数学和统计代考

Suppose that the notional amount of a 4-year interest rate swap of floating in- terest rate for fixed interest rate is  1,000 for the first year and 2,000 for the second and third years, and 4,000 for the fourth year.

(a)Find the swap rate.

(b)Atthe start of the second year, the term structure is

Find the market value of the swap to the receiver at the start of the second year.

### 5.A coupon bond has a spot price of £950.

The bond will pay coupons of  50 in6 months and in one year. The risk free rates are 9% (per year continuously compounded) for 6 month maturity and 10% for one year maturity.

(a)Find the delivery price for a one year forward contract on the bond, with deliveryimmediately after the coupon payment.  数学和统计代考

(b)Suppose that immediately after the first coupon is paid, the continuously compound risk-free rate of interest is 10% for 6 month maturity, and thespot price of the bond has risen to   Determine the value of the long position in the original forward contract entered at time 0.
