Financial Engineering: A Flexible Longevity Bond to Manage Individual Longevity Risk
This paper proposes an individual longevity bond, a combined investment and insurance product to allow individuals to flexibly manage their longevity risk. The bond is a post-retirement product that combines a lifetime income along with a flexible death benefit to meet bequest and liquidity needs. The longevity bonds are issued through a special purpose vehicle which is fully collateralized with a fixed interest portfolio. We apply financial and actuarial models and techniques that provide transparent pricing for interest rate and mortality risk, the construction of optimally immunized bond portfolios and the determination of a loading and solvency margin for systematic longevity risk. We also quantify the natural hedging benefits of the individual bond cash flows arising from the flexible inclusion of both survival dependent income benefits and mortality dependent bequest benefits payable on death.
