Such a situation, called a forfeiture, can be mitigated by the addition of a period-certain feature under which the annuity issuer is required to make annuity payments for at least a certain number of years; if the annuitant outlives the specified period certain, annuity payments continue until the annuitant's death, and if the annuitant dies before the expiration of the period certain, the annuitant's estate or beneficiary is entitled to the remaining payments certain.
