A company owes $10,000 to be paid at each of times 2, 3, and 4. The company plans to meet these obligations with an investment program based on Redington immunization. This strategy will produce a cash flow of 'A' at time 1 and another cash flow of 'B' at time 5. The annual effective rate of interest is 12%. a) Determine A and B. (6 points) b) State the additional condition (beyond the two conditions implicitly shown in part a) that must be satisfied in order for Redington immunization to be accomplished AND State the assumption about interest rate changes that must hold true for Redington immunization to be valid that does not need to hold for full immunization to be valid.
