💵 '''Life contingent annuity''' is an [[Definition:Annuity | annuity]] contract whose periodic payments depend on the continued survival of one or more designated individuals, distinguishing it from an [[Definition:Annuity certain | annuity certain]] that pays for a fixed term regardless of life status. In the insurance industry, this term is essentially synonymous with a [[Definition:Life annuity | life annuity]] — a product issued by a [[Definition:Life and health insurer | life and health insurer]] that converts a sum of money into an income stream lasting as long as the [[Definition:Annuitant | annuitant]] lives. The "life contingent" label is used most often in [[Definition:Actuarial science | actuarial]] and regulatory discourse to emphasize the biometric dependency that differentiates these products from non-contingent payment schedules and to clarify the nature of the insurer's obligation on its balance sheet.

🔄 Payments under a life contingent annuity are calculated using [[Definition:Life contingencies | life contingency]] mathematics, which combine [[Definition:Mortality table | mortality probabilities]] with [[Definition:Discount rate | discount rates]] to determine the [[Definition:Present value | present value]] of future cash flows conditional on survival. The insurer benefits from [[Definition:Mortality pooling | mortality pooling]]: annuitants who die earlier than average effectively subsidize those who live longer, allowing the insurer to offer each individual a higher payment per dollar of [[Definition:Premium | premium]] than would be possible through simple asset drawdown. This pooling advantage — sometimes called the "mortality credit" — is the fundamental economic reason life contingent annuities exist and is unavailable through any non-insurance savings or investment vehicle. The contract may take many forms: a pure [[Definition:Life annuity | straight life annuity]] with no death benefit, a [[Definition:Life annuity with period certain | life annuity with period certain]] guaranteeing a minimum payout duration, a [[Definition:Joint and survivor annuity | joint and survivor annuity]] covering two lives, or a [[Definition:Variable annuity | variable annuity]] with guaranteed lifetime withdrawal benefits that layer investment participation onto the longevity guarantee.

🌐 Regulators across major markets treat life contingent annuities as insurance liabilities subject to dedicated [[Definition:Solvency | solvency]] and [[Definition:Reserve | reserving]] rules, precisely because the insurer's obligation is open-ended and dependent on uncertain human lifespans. Under [[Definition:Solvency II | Solvency II]], the longevity risk embedded in these products attracts a specific [[Definition:Solvency capital requirement (SCR) | solvency capital requirement]] stress test; under [[Definition:IFRS 17 | IFRS 17]], the cash flows must be projected using best-estimate mortality assumptions with explicit risk adjustments. In the United States, [[Definition:Statutory accounting principles (SAP) | statutory reserves]] for life contingent annuities follow prescribed mortality and interest assumptions set by the [[Definition:National Association of Insurance Commissioners (NAIC) | NAIC]]. The product's importance extends beyond individual retirement planning — bulk purchase annuities used in [[Definition:Pension risk transfer | pension risk transfers]] in the UK and the growing [[Definition:Pension buyout | pension buyout]] market globally are fundamentally life contingent annuity transactions at institutional scale, representing some of the largest single-risk transfers in the insurance industry.
