17. Insurer’s mortality bond hedge The insurer sells k bonds At the same time the insurer buys k straight bonds with the same coupon rate as the annuity-based bonds

18. Conclusions (1) There is a growing demand for a long term hedge against improving annuity mortality There is a trend of privatizing social securities systems with insurers taking more longevity risk Insurers will need increased capacity to take on longevity risk and securities markets can provide it

19. Conclusions (2) Compared with the reinsurance market, securitization of mortality risks has longer duration higher capacity possibly lower cost It can help solve the difficulties in managing annuity mortality risk.
