§ 432. Additional funding rules for multiemployer plans in endangered status or critical status

(a) General rule
For purposes of this part, in the case of a multiemployer plan in effect on July 16, 2006—
(1) if the plan is in endangered status—
(A) the plan sponsor shall adopt and implement a funding improvement plan in accordance with the requirements of subsection (c), and
(B) the requirements of subsection (d) shall apply during the funding plan adoption period and the funding improvement period, and
(2) if the plan is in critical status—
(A) the plan sponsor shall adopt and implement a rehabilitation plan in accordance with the requirements of subsection (e), and
(B) the requirements of subsection (f) shall apply during the rehabilitation plan adoption period and the rehabilitation period.
(b) Determination of endangered and critical status
For purposes of this section—
(1) Endangered status
A multiemployer plan is in endangered status for a plan year if, as determined by the plan actuary under paragraph (3), the plan is not in critical status for the plan year and, as of the beginning of the plan year, either—
(A) the plan’s funded percentage for such plan year is less than 80 percent, or
(B) the plan has an accumulated funding deficiency for such plan year, or is projected to have such an accumulated funding deficiency for any of the 6 succeeding plan years, taking into account any extension of amortization periods under section 431 (d).
For purposes of this section, a plan shall be treated as in seriously endangered status for a plan year if the plan is described in both subparagraphs (A) and (B).
(2) Critical status
A multiemployer plan is in critical status for a plan year if, as determined by the plan actuary under paragraph (3), the plan is described in 1 or more of the following subparagraphs as of the beginning of the plan year:
(A) A plan is described in this subparagraph if—
(i) the funded percentage of the plan is less than 65 percent, and
(ii) the sum of—
(I) the fair market value of plan assets, plus
(II) the present value of the reasonably anticipated employer contributions for the current plan year and each of the 6 succeeding plan years, assuming that the terms of all collective bargaining agreements pursuant to which the plan is maintained for the current plan year continue in effect for succeeding plan years,
 is less than the present value of all nonforfeitable benefits projected to be payable under the plan during the current plan year and each of the 6 succeeding plan years (plus administrative expenses for such plan years).
(B) A plan is described in this subparagraph if—
(i) the plan has an accumulated funding deficiency for the current plan year, not taking into account any extension of amortization periods under section 431 (d), or
(ii) the plan is projected to have an accumulated funding deficiency for any of the 3 succeeding plan years (4 succeeding plan years if the funded percentage of the plan is 65 percent or less), not taking into account any extension of amortization periods under section 431 (d).
(C) A plan is described in this subparagraph if—
(i)
(I) the plan’s normal cost for the current plan year, plus interest (determined at the rate used for determining costs under the plan) for the current plan year on the amount of unfunded benefit liabilities under the plan as of the last date of the preceding plan year, exceeds
(II) the present value of the reasonably anticipated employer and employee contributions for the current plan year,
(ii) the present value, as of the beginning of the current plan year, of nonforfeitable benefits of inactive participants is greater than the present value of nonforfeitable benefits of active participants, and
(iii) the plan has an accumulated funding deficiency for the current plan year, or is projected to have such a deficiency for any of the 4 succeeding plan years, not taking into account any extension of amortization periods under section 431 (d).
(D) A plan is described in this subparagraph if the sum of—
(i) the fair market value of plan assets, plus
(ii) the present value of the reasonably anticipated employer contributions for the current plan year and each of the 4 succeeding plan years, assuming that the terms of all collective bargaining agreements pursuant to which the plan is maintained for the current plan year continue in effect for succeeding plan years,
is less than the present value of all benefits projected to be payable under the plan during the current plan year and each of the 4 succeeding plan years (plus administrative expenses for such plan years).
(3) Annual certification by plan actuary
(A) In general
Not later than the 90th day of each plan year of a multiemployer plan, the plan actuary shall certify to the Secretary and to the plan sponsor—
(i) whether or not the plan is in endangered status for such plan year and whether or not the plan is or will be in critical status for such plan year, and
(ii) in the case of a plan which is in a funding improvement or rehabilitation period, whether or not the plan is making the scheduled progress in meeting the requirements of its funding improvement or rehabilitation plan.
(B) Actuarial projections of assets and liabilities
(i) In general In making the determinations and projections under this subsection, the plan actuary shall make projections required for the current and succeeding plan years of the current value of the assets of the plan and the present value of all liabilities to participants and beneficiaries under the plan for the current plan year as of the beginning of such year. The actuary’s projections shall be based on reasonable actuarial estimates, assumptions, and methods that, except as provided in clause (iii), offer the actuary’s best estimate of anticipated experience under the plan. The projected present value of liabilities as of the beginning of such year shall be determined based on the most recent of either—
(I) the actuarial statement required under section 103(d) of the Employee Retirement Income Security Act of 1974 with respect to the most recently filed annual report, or
(II) the actuarial valuation for the preceding plan year.
(ii) Determinations of future contributions Any actuarial projection of plan assets shall assume—
(I) reasonably anticipated employer contributions for the current and succeeding plan years, assuming that the terms of the one or more collective bargaining agreements pursuant to which the plan is maintained for the current plan year continue in effect for succeeding plan years, or
(II) that employer contributions for the most recent plan year will continue indefinitely, but only if the plan actuary determines there have been no significant demographic changes that would make such assumption unreasonable.
(iii) Projected industry activity Any projection of activity in the industry or industries covered by the plan, including future covered employment and contribution levels, shall be based on information provided by the plan sponsor, which shall act reasonably and in good faith.
(C) Penalty for failure to secure timely actuarial certification
Any failure of the plan’s actuary to certify the plan’s status under this subsection by the date specified in subparagraph (A) shall be treated for purposes of section 502(c)(2) of the Employee Retirement Income Security Act of 1974 as a failure or refusal by the plan administrator to file the annual report required to be filed with the Secretary under section 101(b)(1) of such Act.
(D) Notice
(i) In general In any case in which it is certified under subparagraph (A) that a multiemployer plan is or will be in endangered or critical status for a plan year, the plan sponsor shall, not later than 30 days after the date of the certification, provide notification of the endangered or critical status to the participants and beneficiaries, the bargaining parties, the Pension Benefit Guaranty Corporation, and the Secretary of Labor.
(ii) Plans in critical status If it is certified under subparagraph (A) that a multiemployer plan is or will be in critical status, the plan sponsor shall include in the notice under clause (i) an explanation of the possibility that—
(I) adjustable benefits (as defined in subsection (e)(8)) may be reduced, and
(II) such reductions may apply to participants and beneficiaries whose benefit commencement date is on or after the date such notice is provided for the first plan year in which the plan is in critical status.
(iii) Model notice The Secretary, in consultation with the Secretary of Labor [1] shall prescribe a model notice that a multiemployer plan may use to satisfy the requirements under clause (ii).
(c) Funding improvement plan must be adopted for multiemployer plans in endangered status
(1) In general
In any case in which a multiemployer plan is in endangered status for a plan year, the plan sponsor, in accordance with this subsection—
(A) shall adopt a funding improvement plan not later than 240 days following the required date for the actuarial certification of endangered status under subsection (b)(3)(A), and
(B) within 30 days after the adoption of the funding improvement plan—
(i) shall provide to the bargaining parties 1 or more schedules showing revised benefit structures, revised contribution structures, or both, which, if adopted, may reasonably be expected to enable the multiemployer plan to meet the applicable benchmarks in accordance with the funding improvement plan, including—
(I) one proposal for reductions in the amount of future benefit accruals necessary to achieve the applicable benchmarks, assuming no amendments increasing contributions under the plan (other than amendments increasing contributions necessary to achieve the applicable benchmarks after amendments have reduced future benefit accruals to the maximum extent permitted by law), and
(II) one proposal for increases in contributions under the plan necessary to achieve the applicable benchmarks, assuming no amendments reducing future benefit accruals under the plan, and
(ii) may, if the plan sponsor deems appropriate, prepare and provide the bargaining parties with additional information relating to contribution rates or benefit reductions, alternative schedules, or other information relevant to achieving the applicable benchmarks in accordance with the funding improvement plan.
For purposes of this section, the term “applicable benchmarks” means the requirements applicable to the multiemployer plan under paragraph (3) (as modified by paragraph (5)).
(2) Exception for years after process begins
Paragraph (1) shall not apply to a plan year if such year is in a funding plan adoption period or funding improvement period by reason of the plan being in endangered status for a preceding plan year.

(ii) Plans in critical status If the plan’s actuary certifies under subsection (b)(3)(A) for a plan year in any funding plan adoption period or funding improvement period that the plan is in critical status, the funding plan adoption period or funding improvement period, whichever is applicable, shall end as of the close of the plan year preceding the first plan year in the rehabilitation period with respect to such status.
(D) Plans in endangered status at end of period
If the plan’s actuary certifies under subsection (b)(3)(A) for the first plan year following the close of the period described in subparagraph (A) that the plan is in endangered status, the provisions of this subsection and subsection (d) shall be applied as if such first plan year were an initial determination year, except that the plan may not be amended in a manner inconsistent with the funding improvement plan in effect for the preceding plan year until a new funding improvement plan is adopted.
(5) Special rules for seriously endangered plans more than 70 percent funded
(A) In general
If the funded percentage of a plan in seriously endangered status was more than 70 percent as of the beginning of the initial determination year—
(i) paragraphs (3)(B) and (4)(B) shall apply only if the plan’s actuary certifies, within 30 days after the certification under subsection (b)(3)(A) for the initial determination year, that, based on the terms of the plan and the collective bargaining agreements in effect at the time of such certification, the plan is not projected to meet the requirements of paragraph (3)(A) (without regard to paragraphs (3)(B) and (4)(B)), and

A rehabilitation plan must provide annual standards for meeting the requirements of such rehabilitation plan. Such plan shall also include the schedules required to be provided under paragraph (1)(B)(i) and if clause (ii) applies, shall set forth the alternatives considered, explain why the plan is not reasonably expected to emerge from critical status by the end of the rehabilitation period, and specify when, if ever, the plan is expected to emerge from critical status in accordance with the rehabilitation plan.

For purposes of this section—
(A) In general
The rehabilitation period for a plan in critical status is the 10-year period beginning on the first day of the first plan year of the multiemployer plan following the earlier of—
(i) the second anniversary of the date of the adoption of the rehabilitation plan, or
(ii) the expiration of the collective bargaining agreements in effect on the due date for the actuarial certification of critical status for the initial critical year under subsection (a)(1) and covering, as of such date at least 75 percent of the active participants in such multiemployer plan.
If a plan emerges from critical status as provided under subparagraph (B) before the end of such 10-year period, the rehabilitation period shall end with the plan year preceding the plan year for which the determination under subparagraph (B) is made.
(B) Emergence
A plan in critical status shall remain in such status until a plan year for which the plan actuary certifies, in accordance with subsection (b)(3)(A), that the plan is not projected to have an accumulated funding deficiency for the plan year or any of the 9 succeeding plan years, without regard to the use of the shortfall method but taking into account any extension of amortization periods under section 431 (d).

(B) if lower, the accrual rate under the plan on such first day.
The equivalent standard accrual rate shall be determined by the plan sponsor based on the standard or average contribution base units which the plan sponsor determines to be representative for active participants and such other factors as the plan sponsor determines to be relevant. Nothing in this paragraph shall be construed as limiting the ability of the plan sponsor to prepare and provide the bargaining parties with alternative schedules to the default schedule that establish lower or higher accrual and contribution rates than the rates otherwise described in this paragraph.
(7) Automatic employer surcharge
(A) Imposition of surcharge
Each employer otherwise obligated to make a contribution for the initial critical year shall be obligated to pay to the plan for such year a surcharge equal to 5 percent of the contribution otherwise required under the applicable collective bargaining agreement (or other agreement pursuant to which the employer contributes). For each succeeding plan year in which the plan is in critical status for a consecutive period of years beginning with the initial critical year, the surcharge shall be 10 percent of the contribution otherwise so required.
(B) Enforcement of surcharge
The surcharges under subparagraph (A) shall be due and payable on the same schedule as the contributions on which the surcharges are based.

(8) Benefit adjustments
(A) Adjustable benefits
(i) In general Notwithstanding section 411 (d)(6), the plan sponsor shall, subject to the notice requirement under subparagraph (C), make any reductions to adjustable benefits which the plan sponsor deems appropriate, based upon the outcome of collective bargaining over the schedule or schedules provided under paragraph (1)(B)(i).
(ii) Exception for retirees Except in the case of adjustable benefits described in clause (iv)(III), the plan sponsor of a plan in critical status shall not reduce adjustable benefits of any participant or beneficiary whose benefit commencement date is before the date on which the plan provides notice to the participant or beneficiary under subsection (b)(3)(D) for the initial critical year.
(iii) Plan sponsor flexibility The plan sponsor shall include in the schedules provided to the bargaining parties an allowance for funding the benefits of participants with respect to whom contributions are not currently required to be made, and shall reduce their benefits to the extent permitted under this title and considered appropriate by the plan sponsor based on the plan’s then current overall funding status.
(iv) Adjustable benefit defined For purposes of this paragraph, the term “adjustable benefit” means—
(I) benefits, rights, and features under the plan, including post-retirement death benefits, 60-month guarantees, disability benefits not yet in pay status, and similar benefits,
(II) any early retirement benefit or retirement-type subsidy (within the meaning of section 411 (d)(6)(B)(i)) and any benefit payment option (other than the qualified joint and survivor annuity), and
(III) benefit increases that would not be eligible for a guarantee under section 4022A of the Employee Retirement Income Security Act of 1974 on the first day of initial critical year because the increases were adopted (or, if later, took effect) less than 60 months before such first day.
(B) Normal retirement benefits protected
Except as provided in subparagraph (A)(iv)(III), nothing in this paragraph shall be construed to permit a plan to reduce the level of a participant’s accrued benefit payable at normal retirement age.

(I) plan participants and beneficiaries,
(II) each employer who has an obligation to contribute (within the meaning of section 4212(a) of the Employee Retirement Income Security Act of 1974) under the plan, and
(III) each employee organization which, for purposes of collective bargaining, represents plan participants employed by such an employer.
(ii) Content of notice The notice under clause (i) shall contain—

(II) information as to the rights and remedies of plan participants and beneficiaries as well as how to contact the Department of Labor for further information and assistance where appropriate.
(iii) Form and manner Any notice under clause (i)—
(I) shall be provided in a form and manner prescribed in regulations of the Secretary, in consultation with the Secretary of Labor,
(II) shall be written in a manner so as to be understood by the average plan participant, and
