(a) Suspension of certain benefit payments
Notwithstanding section 411, in any case in which benefit payments under an insolvent multiemployer plan exceed the resource benefit level, any such payments of benefits which are not basic benefits shall be suspended, in accordance with this section, to the extent necessary to reduce the sum of such payments and the payments of such basic benefits to the greater of the resource benefit level or the level of basic benefits, unless an alternative procedure is prescribed by the Pension Benefit Guaranty Corporation under section 4022A(g)(5) of the Employee Retirement Income Security Act of 1974.

(b) Definitions
For purposes of this section, for a plan year—

(1) Insolvency
A multiemployer plan is insolvent if the plan's available resources are not sufficient to pay benefits under the plan when due for the plan year, or if the plan is determined to be insolvent under subsection (d).

(2) Resource benefit level
The term "resource benefit level" means the level of monthly benefits determined under subsections (c)(1) and (3) and (d)(3) to be the highest level which can be paid out of the plan's available resources.

(3) Available resources
The term "available resources" means the plan's cash, marketable assets, contributions, withdrawal liability payments, and earnings, less reasonable administrative expenses and amounts owed for such plan year to the Pension Benefit Guaranty Corporation under section 4261(b)(2) of the Employee Retirement Income Security Act of 1974.

(4) Insolvency year
The term "insolvency year" means a plan year in which a plan is insolvent.

(c) Benefit payments under insolvent plans

(1) Determination of resource benefit level
The plan sponsor of a plan in critical status, as described in section 432(b)(2), shall determine in writing the plan's resource benefit level for each insolvency year, based on the plan sponsor's reasonable projection of the plan's available resources and the benefits payable under the plan.

(2) Uniformity of the benefit suspension

(A) The suspension of benefit payments under this section shall, in accordance with regulations prescribed by the Secretary, apply in substantially uniform proportions to the benefits of all persons in pay status under the plan, except that the Secretary may prescribe rules under which benefit suspensions for different participant groups may be varied equitably to reflect variations in contribution rates and other relevant factors including differences in negotiated levels of financial support for plan benefit obligations.

(B) For purposes of this paragraph—

(i) the term "person in pay status" means—

(I) a participant or beneficiary on the last day of the base plan year who, at any time during such year, was paid an early, late, normal, or disability retirement benefit (or a death benefit related to a retirement benefit), and

(II) to the extent provided in regulations prescribed by the Secretary of the Treasury, any other person who is entitled to such a benefit under the plan.

(ii) the base plan year for any plan year is—

(I) if there is a relevant collective bargaining agreement, the last plan year ending at least 6 months before the relevant effective date, or

(II) if there is no relevant collective bargaining agreement, the last plan year ending at least 12 months before the beginning of the plan year.

(iii) a relevant collective bargaining agreement is a collective bargaining agreement—

(I) which is in effect for at least 6 months during the plan year, and

(II) which has not been in effect for more than 36 months as of the end of the plan year.

(iv) the relevant effective date is the earliest of the effective dates for the relevant collective bargaining agreements.

(3) Resource benefit level below level of basic benefits
Notwithstanding paragraph (2), if a plan sponsor determines in writing a resource benefit level for a plan year which is below the level of basic benefits, the payment of all benefits other than basic benefits shall be suspended for that plan year.

(4) Excess resources

(A) In general
If, by the end of an insolvency year, the plan sponsor determines in writing that the plan's available resources in that insolvency year could have supported benefit payments above the resource benefit level for that insolvency year, the plan sponsor shall distribute the excess resources to the participants and beneficiaries who received benefit payments from the plan in that insolvency year, in accordance with regulations prescribed by the Secretary.

(B) Excess resources
For purposes of this paragraph, the term "excess resources" means available resources above the amount necessary to support the resource benefit level, but no greater than the amount necessary to pay benefits for the plan year at the benefit levels under the plan.

(5) Unpaid benefits
If, by the end of an insolvency year, any benefit has not been paid at the resource benefit level, amounts up to the resource benefit level which were unpaid shall be distributed to the participants and beneficiaries, in accordance with regulations prescribed by the Secretary, to the extent possible taking into account the plan's total available resources in that insolvency year.

(6) Retroactive payments
Except as provided in paragraph (4) or (5), a plan is not required to make retroactive benefit payments with respect to that portion of a benefit which was suspended under this section.

(d) Plan sponsor determination

(1) Triennial test
As of the end of the first plan year in which a plan is in critical status, as described in section 432(b)(2), and at least every 3 plan years thereafter (unless the plan is no longer in critical status, as described in section 432(b)(2)), the plan sponsor shall compare the value of plan assets for that plan year with the total amount of benefit payments made under the plan for that plan year. Unless the plan sponsor determines that the value of plan assets exceeds 3 times the total amount of benefit payments, the plan sponsor shall determine whether the plan will be insolvent in any of the next 5 plan years. If the plan sponsor makes such a determination that the plan will be insolvent in any of the next 5 plan years, the plan sponsor shall make the comparison under this paragraph at least annually until the plan sponsor makes a determination that the plan will not be insolvent in any of the next 5 plan years.

(2) Determination of insolvency
If, at any time, the plan sponsor of a plan in critical status, as described in section 432(b)(2), reasonably determines, taking into account the plan's recent and anticipated financial experience, that the plan's available resources are not sufficient to pay benefits under the plan when due for the next plan year, the plan sponsor shall make such determination available to interested parties.

(3) Determination of resource benefit level
The plan sponsor of a plan in critical status, as described in section 432(b)(2), shall determine in writing for each insolvency year the resource benefit level and the level of basic benefits no later than 3 months before the insolvency year.

(4) For purposes of this subsection, the value of plan assets shall be the value of the available plan assets determined under regulations prescribed by the Secretary of the Treasury.

(e) Notice requirements

(1) Impending insolvency
If the plan sponsor of a plan in critical status, as described in section 432(b)(2), determines under subsection (d)(1) or (2) that the plan may become insolvent (within the meaning of subsection (b)(1)), the plan sponsor shall—

(A) notify the Secretary and the parties described in section 101(f)(1) of the Employee Retirement Income Security Act of 1974 of that determination, and

(B) inform the parties described in section 101(f)(1) of the Employee Retirement Income Security Act of 1974 that if insolvency occurs certain benefit payments will be suspended, but that basic benefits will continue to be paid.

(4) Regulations
Notice required by this subsection shall be given in accordance with regulations prescribed by the Pension Benefit Guaranty Corporation, except that notice to the Secretary shall be given in accordance with regulations prescribed by the Secretary.

(f) Financial assistance

(1) Permissive application
If the plan sponsor of an insolvent plan for which the resource benefit level is above the level of basic benefits anticipates that, for any month in an insolvency year, the plan will not have funds sufficient to pay basic benefits, the plan sponsor may apply for financial assistance from the Pension Benefit Guaranty Corporation under section 4261 of the Employee Retirement Income Security Act of 1974.

(2) Mandatory application
