Question:
Consider a guaranteed annuity contract issued by a life insurance company with a rate of 3.08% and a term of 20 years. For a $100,000 nominal amount, the insurance company is promising to pay $183,437.53 (=100,000*(1.0308)^20) to the holder of the guaranteed annuity contract in 20 years. For simplicity, we will assume a lump sum payment. We want to know the interest rate risk exposure to the company if it funds this liability using a 30-year bond with a coupon rate of 3.08% issued at par. Assume that in the first year, rates change to one of the five possible values in row 18 and then stay constant for the next 20 years. For each rate change, calculate two things:
(1) the future value (as of 20 years down the road) of each coupon payment made by the 30-year bond for the next 20 years, and
(2) the value at year 20 of the bond used to fund the obligation. For (1), assume the coupons are reinvested at the new prevailing interest rate. The sum of the reinvested coupons and the value of the bond are the total future value of the assets used to finance the annuity contract.
What is the duration of the 30-year bond as of today?
What is the duration of the guaranteed annuity contract?
Briefly describe how the value of the reinvested coupons and the value of the bond change as a function of interest rate changes.
Will the insurance company be able to meet its obligation to the purchaser of the guaranteed annuity contract?
