Bonus Problem 2 (Optional, Harder, 45 marks) (a) (10 marks) We consider a bond that pays n coupons at the end of each coupon period. The length of each coupon period is T. The bondholder receives a redemption value at nth coupon payment date. The redemption value, face value and coupon rate (over a coupon period) are C, F and r respectively (see P.13 of Lecture Note 4). For any k = 0,1,2.,,,n, we let Pk be the bond price at kth coupon payment date (just after the coupon payment). We let j be the effective interest rate over a coupon payment period. We assume that the yield rate remains unchanged over time. Using the pricing formula of the bond, show that for any non-negative integer k and positive integer m, we have Pk+m Pk = rFamj+ G m provided that k + m 10) issued today. You are given that The bond pays coupon semi-annually (The first coupon is paid 6 months after today). The annual effective yield rate of the bond is 4.8576% and remains unchanged throughout the life of the bond. The book value at the end of 25th month is $3437.6085 The book value at the end of 50th month is $3361.802 Find the book value at the end of 100th month.
