The duration of Bond C is 3.855. Bond D: 5 year 15% government coupon bond, par value $1000. annual coupon payments, YTM=7% (a) (3 marks) Find the price of Bond B, C and D. respectively. (b) (3 marks) Find the Mackulay's duration of Bond D. () (3 marks) If Bond A's yield increases by 0.5%, what is the price of Bond A based on the duration-with-convexity rule! Assume the convexity of the Bond A is 99.77. (a) (5 marks) Suppose you have a liability with a duration of 8 years, the current value of the liability is $1 million.
