Question 11 Show that an investment that pays 22,282 at time 4 and 7,725 at time 6 satisfies the conditions for Redington immunization for liabilities of 15,000 at time 4 and 15,000 at time 5 at a 3% yield rate. (note: due to rounding answers will not match precisely.) Price condition: Modified duration condition: Convexity condition: Question 12 A full immunization strategy is used for a liability of 10,000 at time 5, which uses a payment of 5,500 at time 4 and 4,505.73 at time 5 + b, at a yield rate of 3%. Note: 3 of the 4 unknowns have been provided to simplify the system of equation for you to solve. Find B. How can you prove this meets the conditions of full immunization? b: Conditions for full immunization: Question 11 Show that an investment that pays 22,282 at time 4 and 7,725 at time 6 satisfies the conditions for Redington immunization for liabilities of 15,000 at time 4 and 15,000 at time 5 at a 3% yield rate.
