Example 2.(i) Plan B is a contributory defined benefit plan that permits a participant to elect a single sum distribution equal to the participant's employee contributions, accumulated with interest, with the remainder payable as an annuity. Plan B provides that the probability of death before normal retirement age is not taken into account for purposes of determining actuarial equivalence between the single-sum payment and an annuity at normal retirement age. Based on the applicable mortality table for 2016 and the November 2015 segment rates, the deferred annuity factor at age 60 for lifetime payments commencing at age 65 (determined without taking mortality before age 65 into account) is 10.209.
(ii) Participant T retires at age 60 in 2016 with an accrued benefit of $1,500 per month payable as a straight life annuity commencing at normal retirement age. For benefits commencing at age 60, Plan B provides for an early retirement reduction factor of 75% and an actuarial equivalence factor of 98% for adjusting a straight life annuity to a 10-year certain and life annuity, neither of which is based on the applicable interest and mortality rates under section 417(e)(3). Participant T's benefit commencing at age 60 in the form of a 10-year certain and life annuity would be $1,500 × 75% × 98% = $1,102.50 per month. Participant T elects to receive a single sum payment of $32,000 equal to T's accumulated contributions with interest, and the remainder as a 10-year certain and life annuity.
(iii) The single-sum payment elected by Participant T is a distribution that is determined by reference to Participant T's contributions and interest, and not by reference to a specified portion of the participant's accrued benefit. Therefore, the single-sum payment is not described in paragraph (d)(7)(ii)(A) of this section. In order to satisfy paragraph (d)(7)(ii)(B) of this section, the portion of the participant's accrued benefit that is not settled by the single-sum payment must be no less than the excess of (A) the participant's total accrued benefit over (B) the annuity that is actuarially equivalent to the single-sum payment, (determined using the applicable interest and mortality rates under section 417(e)(3) as applicable), both expressed in the normal form of benefit commencing at normal retirement age. The amount of that actuarially equivalent annuity is determined by dividing Participant T's single-sum payment of $32,000 by the deferred annuity factor for lifetime payments commencing at age 65 under the terms of Plan B (10.209, not considering mortality for the deferral period) and dividing by 12 for an actuarially equivalent monthly benefit commencing at age 65 of $261.21. Thus, in order to satisfy paragraph (d)(7)(ii)(B) of this section, the remaining portion of T's accrued benefit must be at least $1,238.79 per month ($1,500.00−$261.21) payable as a straight life annuity at normal retirement age.
(iv) Based on Plan B's early retirement and optional form factors applied to the remaining portion, the annuity benefit payable to Participant T in the form of a 10-year certain and life annuity beginning at age 60 cannot be less than $910.51 per month ($1,238.79 × 75% × 98%). Participant T receives this in addition to the single-sum payment of $32,000. The 10-year certain and life benefit is not subject to the minimum present value requirements of section 417(e)(3) because it is treated as a separate optional form of benefit under paragraph (d)(7)(iii)(A) of this section.
(v) If, instead, Plan B's terms had provided for a single-sum payment equal to the present value of the participant's employee-provided accrued benefit as determined under section 411(c)(3), then the plan is determining the single-sum payment as the present value of a specified portion of the accrued benefit. In such a case, the plan is using explicit bifurcation as described in paragraph (d)(7)(ii)(A) of this section and the single-sum payment would have to be set equal to the present value, determined under Plan B's terms, of T's employee-provided accrued benefit (which may or may not be equal to T's accumulated contributions and interest, depending on the plan's terms). The remaining annuity benefit payable to Participant T would have been based on an accrued benefit equal to $1,500 per month minus the amount of T's employee-provided accrued benefit.
