Publication 6165 — Defined Benefit Listing of Required Modifications and Information Package (LRM) · 2026-10-03 edition · updated 2026-10-04 · United States
(a) Resumption of Prohibited Payments. If a limitation on prohibited payments under
Section 1(a), Section 2(a), or Section 3 applied to the plan as of a Code § an IRC 436
measurement date, but that limit no longer applies to the plan as of a later Code § IRC 436
measurement date, then that limitation does not apply to benefits with annuity starting
dates that are on or after that later Code § IRC 436 measurement date.
In addition, if elected by the employer in the adoption agreement, after the Code § IRC
436 measurement date on which the limitation on prohibited payments under Section 1(a)
ceases to apply to the plan, any participant or beneficiary who had an annuity starting date
within the period during which that limitation applied to the plan is permitted to make a
new election (within 90 days after the Code § IRC 436 measurement date on which the
limit ceases to apply or, if later, 30 days after receiving notice of the right to make such
election) under which the form of benefit previously elected is modified at a new annuity
starting date to be changed to a single sum payment for the remaining value of the
310 | Defined Benefit Plan LRM Package 08/2020 06/2026
participant or beneficiary’s benefit under the plan, subject to the other rules in this section
of the plan and applicable requirements of Code § IRC 401(a), including spousal consent.
Furthermore, if elected by the employer in the adoption agreement, after the Code § IRC
436 measurement date on which the limitation on prohibited payments under Section 2(a)
ceases to apply to the plan, any participant or beneficiary who had an annuity starting date
within the period during which that limitation applied to the plan is permitted to make a
new election (within 90 days after the Code § IRC 436 measurement date on which the
limit ceases to apply or, if later, 30 days after receiving notice of the right to make such
election) under which the form of benefit previously elected is modified at a new annuity
starting date to be changed to a single sum payment for the remaining value of the
participant or beneficiary’s benefit under the plan, subject to the other rules in this section
of the plan (including Section 1(a)) and applicable requirements of Code § IRC 401(a),
including spousal consent.
(b) Resumption of Benefit Accruals. If a limitation on benefit accruals under Section 2(c)
applied to the plan as of a Code § IRC 436 measurement date, but that limitation no longer
applies to the plan as of a later Code § IRC 436 measurement date, then benefit accruals
shall resume prospectively and that limitation does not apply to benefit accruals that are
based on service on or after that later Code § IRC 436 measurement date, except as
otherwise provided under the plan. The plan shall comply with the rules relating to partial
years of participation and the prohibition on double proration under Department of Labor
Regulations §§ 2530.204-2(c) and (d).
In addition, if elected by the employer in the adoption agreement, benefit accruals that were not permitted to accrue because of the application of Section 2(c) shall be restored when that limitation ceases to apply if the continuous period of the limitation was 12 months or less and the plan’s enrolled actuary certifies that the adjusted funding target attainment percentage for the plan year would not be less than 60% taking into account any restored benefit accruals for the prior plan year.
(c) Shutdown and Other Unpredictable Contingent Event Benefits. If an unpredictable
contingent event benefit with respect to an unpredictable contingent event that occurs
during the plan year is not permitted to be paid after the occurrence of the event because
of the limitation of Section 2(b), but is permitted to be paid later in the same plan year (as
a result of additional contributions or pursuant to the enrolled actuary’s certification of the
adjusted funding target attainment percentage for the plan year that meets the
requirements of Treas. Reg. § 1.436-1(g)(5)(ii)(B)), then that unpredictable contingent
event benefit shall be paid, retroactive to the period that benefit would have been payable
under the terms of the plan (determined without regard to Section 2(b)). If the
unpredictable contingent event benefit does not become payable during the plan year in
accordance with the preceding sentence, then the plan is treated as if it does not provide
for that benefit.
(d) Treatment of Plan Amendments That Do Not Take Effect. If a plan amendment does not take effect as of the effective date of the amendment because of the limitation of Section 1(b) or Section 2(c), but is permitted to take effect later in the same plan year (as a result of additional contributions or pursuant to the enrolled actuary’s certification of the adjusted funding target attainment percentage for the plan year that meets the
311 | Defined Benefit Plan LRM Package 08/2020 06/2026
requirements of Treas. Reg. § 1.436-1(g)(5)(ii)(C)), then the plan amendment must
automatically take effect as of the first day of the plan year (or, if later, the original
effective date of the amendment). If the plan amendment cannot take effect during the
same plan year, then it shall be treated as if it were never adopted, unless the plan
amendment provides otherwise.
