What happens after 15 years with a 15-yeAr certain and life annuity?

After 15 years with a 15-year certain and life annuity, the annuity payments will continue for the rest of the annuitant's life even if they live beyond the initial 15-year period. If the annuitant passes away before the end of the 15 years, the payments will continue to a designated beneficiary for the remainder of the 15 years.
