(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,

(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 is not described in paragraph (5), 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 1084(d) of this title.

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 1084(d) of this title, 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 1084(d) of this title.

(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 1084(d) of this title.

(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 of the Treasury and to the plan sponsor—

(i) whether or not the plan is in endangered status for such plan year, or would be in endangered status for such plan year but for paragraph (5),,¹ whether or not the plan is or will be in critical status for such plan year or for any of the succeeding 5 plan years, and whether or not the plan is or will be in critical and declining 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
Except as provided in clause (iv), 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 1023(d) of this title 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.

(iv) ² Projections relating to critical status in succeeding plan years
Clauses (i) and (ii) (other than the 2nd sentence of clause (i)) may be disregarded by a plan actuary in the case of any certification of whether a plan will be in critical status in a succeeding plan year, except that a plan sponsor may not elect to be in critical status for a plan year under paragraph (4) in any case in which the certification upon which such election would be based is made without regard to such clauses.

(iv) ² Projections of critical and declining status
In determining whether a plan is in critical and declining status as described in subsection (e)(9), clauses (i), (ii), and (iii) shall apply, except that—

(I) if reasonable, the plan actuary shall assume that each contributing employer in compliance continues to comply through the end of the rehabilitation period or such later time as provided in subsection (e)(3)(A)(ii) with the terms of the rehabilitation plan that correspond to the schedule adopted or imposed under subsection (e), and

(II) the plan actuary shall take into account any suspensions of benefits described in subsection (e)(9) adopted in a prior plan year that are still in effect.

(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 1132(c)(2) of this title as a failure or refusal by the plan administrator to file the annual report required to be filed with the Secretary under section 1021(b)(1) of this title.

(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 or in which a plan sponsor elects to be in critical status for a plan year under paragraph (4), 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. In any case in which a plan sponsor elects to be in critical status for a plan year under paragraph (4), the plan sponsor shall notify the Secretary of the Treasury of such election not later than 30 days after the date of such certification or such other time as the Secretary of the Treasury may prescribe by regulations or other guidance.

(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) In the case of a multiemployer plan that would be in endangered status but for paragraph (5), the plan sponsor shall provide notice to the bargaining parties and the Pension Benefit Guaranty Corporation that the plan would be in endangered status but for such paragraph.

(iv) Model notice
The Secretary of the Treasury, in consultation with the Secretary ³ shall prescribe a model notice that a multiemployer plan may use to satisfy the requirements under clauses (ii) and (iii).

(v) Notice of projection to be in critical status in a future plan year
In any case in which it is certified under subparagraph (A)(i) that a multiemployer plan will be in critical status for any of 5 succeeding plan years (but not for the current plan year) and the plan sponsor of such plan has not made an election to be in critical status for the plan year under paragraph (4), the plan sponsor shall, not later than 30 days after the date of the certification, provide notification of the projected critical status to the Pension Benefit Guaranty Corporation.

(4) Election to be in critical status
Notwithstanding paragraph (2) and subject to paragraph (3)(B)(iv)—

(A) the plan sponsor of a multiemployer plan that is not in critical status for a plan year but that is projected by the plan actuary, pursuant to the determination under paragraph (3), to be in critical status in any of the succeeding 5 plan years may, not later than 30 days after the date of the certification under paragraph (3)(A), elect to be in critical status effective for the current plan year,

(B) the plan year in which the plan sponsor elects to be in critical status under subparagraph (A) shall be treated for purposes of this section as the first year in which the plan is in critical status, regardless of the date on which the plan first satisfies the criteria for critical status under paragraph (2), and

(C) a plan that is in critical status under this paragraph shall not emerge from critical status except in accordance with subsection (e)(4)(B).

(5) Special rule
A plan is described in this paragraph if—

(A) as part of the actuarial certification of endangered status under paragraph (3)(A) for the plan year, the plan actuary certifies that the plan is projected to no longer be described in either paragraph (1)(A) or paragraph (1)(B) as of the end of the tenth plan year ending after the plan year to which the certification relates, and

(B) the plan was not in critical or endangered status for the immediately preceding plan year.

(6) Critical and declining status
For purposes of this section, a plan in critical status shall be treated as in critical and declining status if the plan is described in one or more of subparagraphs (A), (B), (C), and (D) of paragraph (2) and the plan is projected to become insolvent within the meaning of section 1426 of this title during the current plan year or any of the 14 succeeding plan years (19 succeeding plan years if the plan has a ratio of inactive participants to active participants that exceeds 2 to 1 or if the funded percentage of the plan is less than 80 percent).

(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. For purposes of this section, such preceding plan year shall be the initial determination year with respect to the funding improvement plan to which it relates.

(3) Funding improvement plan
For purposes of this section—

(A) In general
A funding improvement plan is a plan which consists of the actions, including options or a range of options to be proposed to the bargaining parties, formulated to provide, based on reasonably anticipated experience and reasonable actuarial assumptions, for the attainment by the plan during the funding improvement period of the following requirements:

(i) Increase in plan's funding percentage
The plan's funded percentage as of the close of the funding improvement period equals or exceeds a percentage equal to the sum of—

(I) such percentage as of the beginning of the first plan year for which the plan is certified to be in endangered status pursuant to paragraph (b)(3), plus

(II) 33 percent of the difference between 100 percent and the percentage under subclause (I).

(ii) Avoidance of accumulated funding deficiencies
No accumulated funding deficiency for the last plan year during the funding improvement period (taking into account any extension of amortization periods under section 1084(d) of this title).

(B) Seriously endangered plans
In the case of a plan in seriously endangered status, except as provided in paragraph (5), subparagraph (A)(i)(II) shall be applied by substituting "20 percent" for "33 percent".

(4) Funding improvement period
For purposes of this section—

(A) In general
The funding improvement period for any funding improvement plan adopted pursuant to this subsection is the 10-year period beginning on the first day of the first plan year of the multiemployer plan beginning after the earlier of—

(i) the second anniversary of the date of the adoption of the funding improvement plan, or

(ii) the expiration of the collective bargaining agreements in effect on the due date for the actuarial certification of endangered status for the initial determination year under subsection (b)(3)(A) and covering, as of such due date, at least 75 percent of the active participants in such multiemployer plan.

(B) Seriously endangered plans
In the case of a plan in seriously endangered status, except as provided in paragraph (5), subparagraph (A) shall be applied by substituting "15-year period" for "10-year period".

(C) Coordination with changes in status

(i) Plans no longer in endangered 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 no longer in endangered status and is not in critical status, the funding plan adoption period or funding improvement period, whichever is applicable, shall end as of the close of the 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

(ii) if there is a certification under clause (i), the plan may, in formulating its funding improvement plan, only take into account the rules of paragraph (3)(B) and (4)(B) for plan years in the funding improvement period beginning on or before the date on which the last of the collective bargaining agreements described in paragraph (4)(A)(ii) expires.

(B) Special rule after expiration of agreements
Notwithstanding subparagraph (A)(ii), if, for any plan year ending after the date described in subparagraph (A)(ii), the plan actuary certifies (at the time of the annual certification under subsection (b)(3)(A) for such plan year) that, based on the terms of the plan and collective bargaining agreements in effect at the time of that annual certification, the plan is not projected to be able to meet the requirements of paragraph (3)(A) (without regard to paragraphs (3)(B) and (4)(B)), paragraphs (3)(B) and (4)(B) shall continue to apply for such year.

(6) Updates to funding improvement plan and schedules

(A) Funding improvement plan
The plan sponsor shall annually update the funding improvement plan and shall file the update with the plan's annual report under section 1024 of this title.

A schedule of contribution rates provided by the plan sponsor and relied upon by bargaining parties in negotiating a collective bargaining agreement shall remain in effect for the duration of that collective bargaining agreement.

(7) Imposition of schedule where failure to adopt funding improvement plan

(A) Initial contribution schedule
If—

(i) a collective bargaining agreement providing for contributions under a multiemployer plan that was in effect at the time the plan entered endangered status expires, and

(ii) after receiving one or more schedules from the plan sponsor under paragraph (1)(B), the bargaining parties with respect to such agreement fail to adopt a contribution schedule with terms consistent with the funding improvement plan and a schedule from the plan sponsor,

the plan sponsor shall implement the schedule described in paragraph (1)(B)(i)(I) beginning on the date specified in subparagraph (C).

(B) Subsequent contribution schedule
If—

(i) a collective bargaining agreement providing for contributions under a multiemployer plan in accordance with a schedule provided by the plan sponsor pursuant to a funding improvement plan (or imposed under subparagraph (A)) expires while the plan is still in endangered status, and

(ii) after receiving one or more updated schedules from the plan sponsor under paragraph (6)(B), the bargaining parties with respect to such agreement fail to adopt a contribution schedule with terms consistent with the updated funding improvement plan and a schedule from the plan sponsor,

then the contribution schedule applicable under the expired collective bargaining agreement, as updated and in effect on the date the collective bargaining agreement expires, shall be implemented by the plan sponsor beginning on the date specified in subparagraph (C).

(C) Date of implementation
The date specified in this subparagraph is the date which is 180 days after the date on which the collective bargaining agreement described in subparagraph (A) or (B) expires.

(D) Failure to make scheduled contributions
Any failure to make a contribution under a schedule of contribution rates provided under this paragraph shall be treated as a delinquent contribution under section 1145 of this title and shall be enforceable as such.

(8) Funding plan adoption period
For purposes of this section, the term "funding plan adoption period" means the period beginning on the date of the certification under subsection (b)(3)(A) for the initial determination year and ending on the day before the first day of the funding improvement period.

(d) Rules for operation of plan during adoption and improvement periods

(1) Compliance with funding improvement plan

(A) In general
A plan may not be amended after the date of the adoption of a funding improvement plan under subsection (c) so as to be inconsistent with the funding improvement plan.

(B) Special rules for benefit increases
A plan may not be amended after the date of the adoption of a funding improvement plan under subsection (c) so as to increase benefits, including future benefit accruals, unless the plan actuary certifies that such increase is paid for out of additional contributions not contemplated by the funding improvement plan, and, after taking into account the benefit increase, the multiemployer plan still is reasonably expected to meet the applicable benchmark on the schedule contemplated in the funding improvement plan.

(2) Special rules for plan adoption period
During the period beginning on the date of the certification under subsection (b)(3)(A) for the initial determination year and ending on the date of the adoption of a funding improvement plan—

(A) the plan sponsor may not accept a collective bargaining agreement or participation agreement with respect to the multiemployer plan that provides for—

(i) a reduction in the level of contributions for any participants,

(ii) a suspension of contributions with respect to any period of service, or

(iii) any new direct or indirect exclusion of younger or newly hired employees from plan participation, and

(B) no amendment of the plan which increases the liabilities of the plan by reason of any increase in benefits, any change in the accrual of benefits, or any change in the rate at which benefits become nonforfeitable under the plan may be adopted unless the amendment is required as a condition of qualification under part I of subchapter D of chapter 1 of title 26 or to comply with other applicable law.

(e) Rehabilitation plan must be adopted for multiemployer plans in critical status

(1) In general
In any case in which a multiemployer plan is in critical status for a plan year, the plan sponsor, in accordance with this subsection—

(A) shall adopt a rehabilitation plan not later than 240 days following the required date for the actuarial certification of critical status under subsection (b)(3)(A), and

(B) within 30 days after the adoption of the rehabilitation 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 emerge from critical status in accordance with the rehabilitation 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 emerging from critical status in accordance with the rehabilitation plan.

The schedule or schedules described in subparagraph (B)(i) shall reflect reductions in future benefit accruals and adjustable benefits, and increases in contributions, that the plan sponsor determines are reasonably necessary to emerge from critical status. One schedule shall be designated as the default schedule and such schedule shall assume that there are no increases in contributions under the plan other than the increases necessary to emerge from critical status after future benefit accruals and other benefits (other than benefits the reduction or elimination of which are not permitted under section 1054(g) of this title) have been reduced to the maximum extent permitted by law.

(2) Exception for years after process begins
Paragraph (1) shall not apply to a plan year if such year is in a rehabilitation plan adoption period or rehabilitation period by reason of the plan being in critical status for a preceding plan year. For purposes of this section, such preceding plan year shall be the initial critical year with respect to the rehabilitation plan to which it relates.

(3) Rehabilitation plan
For purposes of this section—

(A) In general
A rehabilitation plan is a plan which consists of—

(i) actions, including options or a range of options to be proposed to the bargaining parties, formulated, based on reasonably anticipated experience and reasonable actuarial assumptions, to enable the plan to cease to be in critical status by the end of the rehabilitation period and may include reductions in plan expenditures (including plan mergers and consolidations), reductions in future benefit accruals or increases in contributions, if agreed to by the bargaining parties, or any combination of such actions, or

(ii) if the plan sponsor determines that, based on reasonable actuarial assumptions and upon exhaustion of all reasonable measures, the plan can not reasonably be expected to emerge from critical status by the end of the rehabilitation period, reasonable measures to emerge from critical status at a later time or to forestall possible insolvency (within the meaning of section 1426 of this title).

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.

(B) Updates to rehabilitation plan and schedules

(i) Rehabilitation plan
The plan sponsor shall annually update the rehabilitation plan and shall file the update with the plan's annual report under section 1024 of this title.

A schedule of contribution rates provided by the plan sponsor and relied upon by bargaining parties in negotiating a collective bargaining agreement shall remain in effect for the duration of that collective bargaining agreement.

(C) Imposition of schedule where failure to adopt rehabilitation plan

(i) Initial contribution schedule
If—

(I) a collective bargaining agreement providing for contributions under a multiemployer plan that was in effect at the time the plan entered critical status expires, and

(II) after receiving one or more schedules from the plan sponsor under paragraph (1)(B), the bargaining parties with respect to such agreement fail to adopt a contribution schedule with terms consistent with the rehabilitation plan and a schedule from the plan sponsor under paragraph (1)(B)(i),

 the plan sponsor shall implement the schedule described in the last sentence of paragraph (1) beginning on the date specified in clause (iii).

(ii) Subsequent contribution schedule
If—

(I) a collective bargaining agreement providing for contributions under a multiemployer plan in accordance with a schedule provided by the plan sponsor pursuant to a rehabilitation plan (or imposed under subparagraph (C)(i)) expires while the plan is still in critical status, and

(II) after receiving one or more updated schedules from the plan sponsor under subparagraph (B)(ii), the bargaining parties with respect to such agreement fail to adopt a contribution schedule with terms consistent with the updated rehabilitation plan and a schedule from the plan sponsor,

 then the contribution schedule applicable under the expired collective bargaining agreement, as updated and in effect on the date the collective bargaining agreement expires, shall be implemented by the plan sponsor beginning on the date specified in clause (iii).

(iii) Date of implementation
The date specified in this subparagraph is the date which is 180 days after the date on which the collective bargaining agreement described in clause (i) or (ii) expires.

(iv) Failure to make scheduled contributions
Any failure to make a contribution under a schedule of contribution rates provided under this subsection shall be treated as a delinquent contribution under section 1145 of this title and shall be enforceable as such.

(4) Rehabilitation period
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

(i) In general
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—

(I) the plan is not described in one or more of the subparagraphs in subsection (b)(2) as of the beginning of the plan year;

(II) 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 1084(d)(2) of this title or section 1084 of this title (as in effect prior to the enactment of the Pension Protection Act of 2006); and

(III) the plan is not projected to become insolvent within the meaning of section 1426 of this title for any of the 30 succeeding plan years.

(ii) Plans with certain amortization extensions

(I) Special emergence rule

Notwithstanding clause (i), a plan in critical status that has an automatic extension of amortization periods under section 1084(d)(1) of this title shall no longer be in critical status if the plan actuary certifies for a plan year, in accordance with subsection (b)(3)(A), that—

(aa) 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 1084(d)(1) of this title; and

(bb) the plan is not projected to become insolvent within the meaning of section 1426 of this title for any of the 30 succeeding plan years,

 regardless of whether the plan is described in one or more of the subparagraphs in subsection (b)(2) as of the beginning of the plan year.

(II) Reentry into critical status

A plan that emerges from critical status under subclause (I) shall not reenter critical status for any subsequent plan year unless—

(aa) the plan is 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 1084(d) of this title; or

(bb) the plan is projected to become insolvent within the meaning of section 1426 of this title for any of the 30 succeeding plan years.

(5) Rehabilitation plan adoption period
For purposes of this section, the term "rehabilitation plan adoption period" means the period beginning on the date of the certification under subsection (b)(3)(A) for the initial critical year and ending on the day before the first day of the rehabilitation period.

(6) Limitation on reduction in rates of future accruals
Any reduction in the rate of future accruals under the default schedule described in the last sentence of paragraph (1) shall not reduce the rate of future accruals below—

(A) a monthly benefit (payable as a single life annuity commencing at the participant's normal retirement age) equal to 1 percent of the contributions required to be made with respect to a participant, or the equivalent standard accrual rate for a participant or group of participants under the collective bargaining agreements in effect as of the first day of the initial critical year, or

(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 contributions for the initial critical year shall be obligated to pay to the plan for such year a surcharge equal to 5 percent of the contributions 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 contributions otherwise so required.

(B) Enforcement of surcharge

(ii) The plan sponsor determines, in a written record to be maintained throughout the period of the benefit suspension, that the plan is still projected to become insolvent unless benefits are suspended under this paragraph, although all reasonable measures to avoid insolvency have been taken (and continue to be taken during the period of the benefit suspension). In its determination, the plan sponsor may take into account factors including the following:

(I) Current and past contribution levels.

(aa) the number of months during the period beginning with the month after the month in which occurs the effective date of the suspension and ending with the month during which the participant or beneficiary attains the age of 80, by

(bb) 60 months.

(iii) No benefits based on disability (as defined under the plan) may be suspended under this paragraph.

(iv) Any suspensions of benefits, in the aggregate (and, if applicable, considered in combination with a partition of the plan under section 1413 of this title), shall be reasonably estimated to achieve, but not materially exceed, the level that is necessary to avoid insolvency.

(v) In any case in which a suspension of benefits with respect to a plan is made in combination with a partition of the plan under section 1413 of this title, the suspension of benefits may not take effect prior to the effective date of such partition.

(XI) Extent to which benefits are attributed to service with an employer that failed to pay its full withdrawal liability.

(vii) In the case of a plan that includes the benefits described in clause (III), benefits suspended under this paragraph shall—

(I) first, be applied to the maximum extent permissible to benefits attributable to a participant's service for an employer which withdrew from the plan and failed to pay (or is delinquent with respect to paying) the full amount of its withdrawal liability under section 1381(b)(1) of this title or an agreement with the plan,

(I) such action is accompanied by equitable benefit improvements in accordance with clause (ii) for all participants and beneficiaries whose benefit commencement dates were before the first day of the plan year for which the benefit improvement for such participant or beneficiary not in pay status took effect; and

(II) the plan actuary certifies that after taking into account such benefits improvements the plan is projected to avoid insolvency indefinitely under section 1426 of this title.

(ii) Equitable distribution of benefit improvements

(I) Limitation

The projected value of the total liabilities for benefit improvements for participants and beneficiaries not in pay status by the date of the first day of the plan year in which the benefit improvements are proposed to take effect, as determined as of such date, may not exceed the projected value of the liabilities arising from benefit improvements for participants and beneficiaries with benefit commencement dates prior to the first day of such plan year, as so determined.

If the Secretary of the Treasury, in consultation with the Pension Benefit Guaranty Corporation and the Secretary of Labor, rejects a plan sponsor's application, the Secretary of the Treasury shall provide notice to the plan sponsor detailing the specific reasons for the rejection, including reference to the specific requirement not satisfied.

(A) In general
Any increase in the contribution rate (or other increase in contribution requirements unless due to increased levels of work, employment, or periods for which compensation is provided) that is required or made in order to enable the plan to meet the requirement of the funding improvement plan or rehabilitation plan shall be disregarded in determining the allocation of unfunded vested benefits to an employer under section 1391 of this title and in determining the highest contribution rate under section 1399(c) of this title, except for purposes of determining the unfunded vested benefits attributable to an employer under section 1391(c)(4) of this title or a comparable method approved under section 1391(c)(5) of this title.
