29 CFR § 4044.53 - Mortality assumptions.
(a) General rule. Subject to paragraph (b) of this section (regarding certain death benefits), the plan administrator shall use the mortality factors prescribed in paragraphs (c), (d), (e), (f), and (g) of this section to value benefits under § 4044.52.
(b) Certain death benefits. If an annuity for one person is in pay status on the valuation date, and if the payment of a death benefit after the valuation date to another person, who need not be identifiable on the valuation date, depends in whole or in part on the death of the pay status annuitant, then the plan administrator shall value the death benefit using—
(1) The mortality rates that are applicable to the annuity in pay status under this section to represent the mortality of the pay status annuitant; and
(2) The mortality rates under paragraph (c) of this section to represent the mortality of the death beneficiary.
(c) Healthy lives. If the individual is not disabled under paragraph (f) of this section, the plan administrator will value the benefit using—
(1) For male participants, the rates in Table 1 of appendix A to this part projected from 1994 to the calendar year in which the valuation date occurs plus 10 years using Scale AA from Table 2 of appendix A to this part; and
(2) For female participants, the rates in Table 3 of appendix A to this part projected from 1994 to the calendar year in which the valuation date occurs plus 10 years using Scale AA from Table 4 of appendix A to this part.
(d) Social Security disabled lives. If the individual is Social Security disabled under paragraph (f)(1) of this section, the plan administrator will value the benefit using—
(1) For male participants, the rates in Table 5 of appendix A to this part; and
(2) For female participants, the rates in Table 6 of appendix A to this part.
(e) Non-Social Security disabled lives. If the individual is non-Social Security disabled under paragraph (f)(2) of this section, the plan administrator will value the benefit at each age using—
(1) For male participants, the lesser of—
(i) The rate determined from Table 1 of appendix A to this part projected from 1994 to the calendar year in which the valuation date occurs plus 10 years using Scale AA from Table 2 of appendix A to this part and setting the resulting table forward three years, or
(ii) The rate in Table 5 of appendix A to this part.
(2) For female participants, the lesser of—
(i) The rate determined from Table 3 of appendix A to this part projected from 1994 to the calendar year in which the valuation date occurs plus 10 years using Scale AA from Table 4 of appendix A to this part and setting the resulting table forward three years, or
(ii) The rate in Table 6 of appendix A to this part.
(f) Definitions of disability—(1) Social Security disabled. A participant is Social Security disabled if, on the valuation date, the participant is less than age 65 and has a benefit in pay status that—
(i) Is being received as a disability benefit under a plan provision requiring either receipt of or eligibility for Social Security disability benefits, or
(ii) Was converted under the plan's terms from a disability benefit under a plan provision requiring either receipt of or eligibility for Social Security disability benefits to an early or normal retirement benefit for any reason other than a change in the participant's health status.
(2) Non-Social Security disabled. A participant is non-Social Security disabled if, on the valuation date, the participant is less than age 65, is not Social Security disabled, and has a benefit in pay status that—
(i) Is being received as a disability benefit under the plan, or
(ii) Was converted under the plan's terms from a disability benefit to an early or normal retirement benefit for any reason other than a change in the participant's health status.
(g) Contingent annuitant mortality during deferral period. If a participant's joint and survivor benefit is valued as a deferred annuity, the mortality of the contingent annuitant during the deferral period will be disregarded.
