SUPPLEMENTARY INFORMATION:

Executive Summary

Purpose of Regulatory Action

    This rulemaking is needed to implement statutory changes affecting 
the determination of an employer's withdrawal liability and annual 
withdrawal liability payment amount when the employer withdraws from a 
multiemployer plan. The final regulation provides simplified methods 
for determining withdrawal liability and annual payment amounts, which 
a multiemployer plan sponsor can adopt to satisfy the statutory 
requirements and to reduce administrative burden. In this final rule, 
PBGC adopts its proposed changes implementing statutory changes and 
providing simplified methods, with some modifications in response to 
public comments.
    PBGC's legal authority for this action is based on section 
4002(b)(3) of the Employee Retirement Income Security Act of 1974 
(ERISA), which authorizes PBGC to issue regulations to carry out the 
purposes of title IV of ERISA; section 305(g) \1\ of ERISA, which 
provides the statutory requirements for changes to withdrawal 
liability; section 4001 of ERISA (Definitions); section 4204 of ERISA 
(Sale of Assets); section 4206 of ERISA (Adjustment for Partial 
Withdrawal); section 4207 (Reduction or Waiver of Complete Withdrawal 
Liability); section 4211 of ERISA (Methods for Computing Withdrawal 
Liability); and section 4219 of ERISA (Notice, Collection, Etc., of 
Withdrawal Liability). Section 305(g)(5) of ERISA directs PBGC to 
provide simplified methods for multiemployer plan sponsors to use in 
determining withdrawal liability and annual payment amounts.
---------------------------------------------------------------------------

    \1\ Section 305(g) of ERISA and section 432(g) of the Internal 
Revenue Code (Code) are parallel provisions in ERISA and the Code.
---------------------------------------------------------------------------

Major Provisions of the Regulatory Action

    This final regulation amends PBGC's regulations on Allocating 
Unfunded Vested Benefits to Withdrawing Employers (29 CFR part 4211) 
and Notice, Collection, and Redetermination of Withdrawal Liability (29 
CFR part 4219). The changes implement statutory changes affecting the 
determination of an employer's withdrawal liability and annual 
withdrawal liability payment amount and provide simplified methods for 
a plan sponsor to--
     Disregard reductions and suspensions of nonforfeitable 
benefits in determining the plan's unfunded vested benefits for 
purposes of calculating withdrawal liability.
     Disregard certain contribution increases if the plan is 
using the presumptive, modified presumptive, or rolling-5 method for 
purposes of determining the allocation of unfunded vested benefits to 
an employer.
     Disregard certain contribution increases for purposes of 
determining an employer's annual withdrawal liability payment.

V. Compliance With Rulemaking Guidelines

I. Background

    The Pension Benefit Guaranty Corporation (PBGC) administers two 
insurance programs for private-sector defined benefit pension plans 
under title IV of the Employee Retirement

[[Page 1257]]

Income Security Act of 1974 (ERISA): A single-employer plan termination 
insurance program and a multiemployer plan insolvency insurance 
program. In general, a multiemployer pension plan is a collectively 
bargained plan involving two or more unrelated employers. This final 
rule deals with multiemployer plans.
    Under sections 4201 through 4225 of ERISA, when a contributing 
employer withdraws from an underfunded multiemployer plan, the plan 
sponsor assesses withdrawal liability against the employer. Withdrawal 
liability represents a withdrawing employer's proportionate share of 
the plan's unfunded benefit obligations. To assess withdrawal 
liability, the plan sponsor must determine the withdrawing employer's: 
(1) Allocable share of the plan's unfunded vested benefits (the value 
of nonforfeitable benefits that exceeds the value of plan assets) as 
provided under section 4211, and (2) annual withdrawal liability 
payment as provided under section 4219.
    There are four statutory allocation methods for determining a 
withdrawing employer's allocable share of the plan's unfunded vested 
benefits under section 4211 of ERISA: The presumptive method, the 
modified presumptive method, the rolling-5 method, and the direct 
attribution method. Under the first three methods, the basic formula 
for an employer's withdrawal liability is one or more pools of unfunded 
vested benefits times the withdrawing employer's allocation fraction--
---------------------------------------------------------------------------

    \2\ Under ERISA sections 4211(b) and (c), the presumptive method 
provides for 20 distinct year-by-year liability pools (each pool 
represents the year in which the unfunded liability arose), the 
modified presumptive method provides for two liability pools, and 
the rolling-5 method provides for a single liability pool computed 
as of the end of the plan year preceding the plan year when the 
withdrawal occurs.
[GRAPHIC] [TIFF OMITTED] TR08JA21.008

    The withdrawing employer's allocation fraction is generally equal 
to the withdrawing employer's required contributions over all 
employers' contributions over the 5 years preceding the relevant period 
or periods. Under the fourth method, the direct attribution method, an 
employer's withdrawal liability is based on the benefits and assets 
attributed directly to the employer's participants' service, and a 
portion of the unfunded benefit obligations not attributable to any 
present employer.
    PBGC's regulation on Allocating Unfunded Vested Benefits to 
Withdrawing Employers (29 CFR part 4211) provides modifications to the 
allocation methods that plan sponsors may adopt. Part 4211 also 
provides a process that plan sponsors may use to request approval of 
other methods.
    A withdrawn employer makes annual withdrawal liability payments at 
a set rate over the number of years necessary to amortize its 
withdrawal liability, generally limited to a period of 20 years. If any 
of an employer's withdrawal liability remains unpaid under the payment 
schedule after 20 years, the unpaid amount may be allocated to other 
employers in addition to their basic withdrawal liability.
    Annual withdrawal liability payments are designed to approximate 
the employer's annual contributions before its withdrawal. The basic 
formula for the annual withdrawal liability payment under section 
4219(c) of ERISA is a contribution rate multiplied by a contribution 
base. Specifically, the annual withdrawal liability payment is 
determined as follows--
[GRAPHIC] [TIFF OMITTED] TR08JA21.009

    As the basic formulas show, withdrawal liability and an employer's 
annual withdrawal liability payment depend, among other things, on the 
value of unfunded vested benefits and the amount of contributions.
    In response to financial difficulties faced by some multiemployer 
plans, Congress made statutory changes in 2006 and 2014 that affect 
benefits and contributions under these plans. The four types of changes 
provided for are shown in the following table:

[[Page 1258]]



------------------------------------------------------------------------
 
------------------------------------------------------------------------
Adjustable benefit reductions  Reductions in adjustable benefits (e.g.,
                                post-retirement death benefits, early
                                retirement benefits) and reductions
                                arising from a restriction on lump sums
                                and other benefits.\3\
Benefit Suspensions..........  Temporary or permanent suspension of any
                                current or future payment obligation of
                                the plan to any participant or
                                beneficiary under the plan, whether or
                                not in pay status at the time of the
                                benefit suspension.\4\
Surcharges...................  Surcharges, calculated as a percentage of
                                required contributions, that certain
                                underfunded plans are required to impose
                                on contributing employers.\5\
Contribution Increases.......  Contribution increases that plan trustees
                                may require under a funding improvement
                                or rehabilitation plan.\6\
------------------------------------------------------------------------

    While each of the changes has its own requirements, they generally 
are all required to be ``disregarded'' by the plan sponsor in 
determining an employer's withdrawal liability. The statutory 
``disregard'' rules require in effect that all computations in 
determining and assessing withdrawal liability be made using values 
that do not reflect the lowering of benefits or raising of 
contributions required to be disregarded.
---------------------------------------------------------------------------

    \3\ Section 305(e)(8) and (f) of ERISA and section 432(e)(8) and 
(f) of the Code.
    \4\ Section 305(e)(9) of ERISA and section 432(e)(9) of the 
Code. The Department of the Treasury must approve an application for 
a benefit suspension, in consultation with PBGC and the Department 
of Labor, upon finding that the plan is eligible for the suspension 
and has satisfied the criteria specified by the Multiemployer 
Pension Reform Act of 2014, Public Law 113-235 (MPRA). The 
Department of the Treasury has jurisdiction over benefit suspensions 
and issued a final rule implementing the MPRA provisions on April 
28, 2016 (81 FR 25539).
    \5\ Under section 305(e)(7) of ERISA and section 432(e)(7) of 
the Code, each employer otherwise obligated to make contributions 
for the initial plan year and any subsequent plan year that a plan 
is in critical status must pay a surcharge to the plan for such plan 
year, until the effective date of a collective bargaining agreement 
(or other agreement pursuant to which the employer contributes) that 
includes terms consistent with the rehabilitation plan adopted by 
the plan sponsor.
    \6\ The plan sponsor of a plan in endangered status for a plan 
year must adopt a funding improvement plan under section 305(c) of 
ERISA and section 432(c) of the Code. The plan sponsor of a plan in 
critical status for a plan year must adopt a rehabilitation plan 
under section 305(e) of ERISA and section 432(e) of the Code.
---------------------------------------------------------------------------

    The Pension Protection Act of 2006, Public Law 109-280 (PPA 2006), 
amended ERISA's withdrawal liability rules to require a plan sponsor to 
disregard the adjustable benefits reductions in section 305(e)(8) of 
ERISA and the elimination of accelerated forms of distribution in 
section 305(f) of ERISA (which, for purposes of this preamble are 
referred to as adjustable benefit reductions) in determining a plan's 
unfunded vested benefits. PPA 2006 also requires a plan sponsor to 
disregard the contribution surcharges in section 305(e)(7) of ERISA in 
determining the allocation of unfunded vested benefits.
    PBGC issued a final rule in December 2008 (73 FR 79628) 
implementing these PPA 2006 ``disregard'' rules by modifying the 
definition of ``nonforfeitable benefit'' for purposes of PBGC's 
regulations on Allocating Unfunded Vested Benefits to Withdrawing 
Employers (29 CFR part 4211) and on Notice, Collection, and 
Redetermination of Withdrawal Liability (29 CFR part 4219). PBGC 
provided simplified methods to determine withdrawal liability for plan 
sponsors required to disregard adjustable benefit reductions in 
Technical Update 10-3 (July 15, 2010). The 2008 final rule also 
excluded the employer surcharge from the numerator and denominator of 
the allocation fractions used under section 4211 of ERISA. The preamble 
included an example of the application of the exclusion of surcharge 
amounts from contributions in the allocation fraction.
    The Multiemployer Pension Reform Act of 2014, Public Law 113-235 
(MPRA), made further amendments to the withdrawal liability rules and 
consolidated them with the PPA 2006 changes. The additional MPRA 
amendments require a plan sponsor to disregard benefit suspensions in 
determining the plan's unfunded vested benefits for a period of 10 
years after the effective date of a benefit suspension. MPRA also 
requires a plan sponsor to disregard certain contribution increases in 
determining the allocation of unfunded vested benefits. A plan sponsor 
must also disregard surcharges and those contribution increases in 
determining an employer's annual withdrawal liability payment under 
section 4219 of ERISA. The MPRA amendments apply to benefit suspensions 
and contribution increases that go into effect during plan years 
beginning after December 31, 2014, and to surcharges for which the 
obligation accrues on or after December 31, 2014.
    Congress also authorized PBGC to create simplified methods for 
applying the ``disregard'' rules.

Proposed Regulation

    On February 6, 2019 (at 84 FR 2075), PBGC published a proposed rule 
to explain the PPA 2006 and MPRA ``disregard'' requirements and PBGC's 
simplified methods. Each simplified method provided applies to one or 
more specific aspects of the process of determining and assessing 
withdrawal liability.
    PBGC provided a 60-day comment period and received eight comment 
letters from: Actuarial consulting firms; associations representing 
multiemployer plans, pension practitioners, and contributing employers; 
and a practitioner. To address the comments, PBGC is making 
modifications and clarifications, adding examples, and providing 
additional simplified methods. The public comments, PBGC's responses, 
and the provisions of this final rule are discussed below.

II. Discussion of Final Regulation and Public Comments

Overview

    This final rule, like the proposed, implements the PPA 2006 and 
MPRA requirements to disregard adjustable benefit reductions, benefit 
suspensions, surcharges, and contribution increases. All of the 
commenters commented on the provision in the proposed rule implementing 
the exception to the disregard rules for a contribution increase that 
provides an increase in benefits. The provision, comments, and changes 
to the proposed rule in response to the comments are discussed in more 
detail in section IV.A. of the preamble. Except for those changes, the 
final rule is substantially the same as the proposed rule.
    The final rule, like the proposed rule, provides: (1) Simplified 
methods for disregarding adjustable benefit reductions and benefit 
suspensions; and (2) simplified methods for disregarding certain 
contribution increases in determining the allocation of unfunded vested 
benefits to an employer and the annual withdrawal liability payment 
amount. A plan sponsor may, but is not required to, adopt any one or 
more of the simplified methods to use in the calculation of determining 
and assessing withdrawal liability but must follow the statutory 
withdrawal liability rules for all other aspects. In response to 
comments, PBGC made clarifications and improvements to the simplified 
methods, which are discussed below in sections III and IV of the 
preamble.

[[Page 1259]]

    Because some of the commenters found the examples illustrating 
calculations using the simplified methods helpful, PBGC is adding some 
of the examples to the operative text and to an appendix to part 4211. 
The final rule also eliminates some language that merely repeats 
statutory provisions and makes other editorial changes.

``Safe Harbors''

    One commenter asked PBGC to clarify that the simplified methods are 
``safe harbor'' methods, but that alternate simplified methods could be 
appropriate. The commenter requested that PBGC consider providing plan 
sponsors with the opportunity to seek approval for an alternative 
simplified method. Under the final rule, PBGC clarifies that, similar 
to a safe harbor, a plan sponsor that adopts one of the simplified 
methods satisfies the requirements of the applicable statutory 
provision and regulations. Consistent with the proposed rule, a plan 
sponsor may choose to use an alternative approach that satisfies the 
requirements of the applicable statutory provisions and regulations 
rather than any of the simplified methods. While PBGC does not approve 
alternative simplified methods on a plan-by-plan basis, PBGC welcomes 
informal consultations with trustees and their advisors on whether an 
alternative approach could satisfy the requirements of the applicable 
statutory provisions and regulations. In addition, PBGC invited 
comments in the proposed rule on other simplified methods that a plan 
might use to satisfy certain requirements in section 305(g) of ERISA 
and incorporated changes in the final rule in response to comments 
received. PBGC encourages trustees and their advisors to inform PBGC of 
additional simplified methods to consider for a future rulemaking.

Effective and Applicability Dates

    Under the proposed rule, the changes relating to simplified methods 
would be applicable to employer withdrawals that occur on or after the 
effective date of the final rule. It further proposed that the changes 
relating to MPRA benefit suspensions and contribution increases for 
determining an employer's withdrawal liability would apply to plan 
years beginning after December 31, 2014, and to surcharges the 
obligation for which occur on or after December 31, 2014. The proposed 
rule did not provide an effective date.
    Three commenters asked for clarification of the effective date and 
were concerned that the rule would require retroactive application. Two 
commenters were concerned that plans could be required to implement 
changes at some time other than the beginning or end of a specified 
plan year. The commenters made specific recommendations for an 
applicability date. One commenter recommended that the date be based on 
withdrawals in plan years beginning on or after the effective date of 
the final rule. A second commenter recommended that the regulation 
apply for withdrawals beginning in the plan year that next follows the 
plan year in which the rule becomes effective with a transition period 
in the event the next plan year begins within 6 months following the 
issuance of the final regulation. A third commenter recommended a 
transition period of at least 1 plan year to give plans time to 
evaluate and consider the methodologies included in the regulation for 
contribution increases that provide an increase in benefits. PBGC did 
not adopt this suggested transition period because the final rule does 
not include the proposed rule's provision implementing the exception 
under section 305(g)(3) of ERISA for additional contributions used to 
provide an increase in benefits. The provision is discussed in section 
IV.A. of the preamble.
    In response to the comments about the rule's effective date, PBGC 
is clarifying that the changes made by the final rule apply to plans 
prospectively. Accordingly, the final rule is effective February 8, 
2021 and applies to employer withdrawals from multiemployer plans that 
occur in plan years beginning on or after the effective date. Just as 
before the final rule, plan sponsors may apply their own reasonable 
interpretations of the statutory provisions to calculate an employer's 
withdrawal liability. Plan sponsors may, but are not required to, adopt 
the simplified methods provided in the final rule. In addition, as 
suggested by one commenter, PBGC added effective dates in parts 4211 
and 4219 for the new sections providing simplified methods.

III. Regulatory Changes To Reflect Benefit Decreases

A. Requirement To Disregard Adjustable Benefit Reductions and Benefit 
Suspensions (Sec.  4211.6)

    Under the basic methodology explained in section I above, a plan 
sponsor must calculate the value of unfunded vested benefits (the value 
of nonforfeitable benefits that exceeds the value of plan assets) \7\ 
to determine a withdrawing employer's liability. In computing 
nonforfeitable benefits, under section 305(g)(1) of ERISA, a plan 
sponsor is required to disregard certain adjustable benefit reductions 
and benefit suspensions.
---------------------------------------------------------------------------

    \7\ The term ``unfunded vested benefits'' is defined in section 
4213(c) of ERISA. However, for purposes of PBGC's notice, 
collection, and redetermination of withdrawal liability regulation 
(29 CFR part 4219), the calculation of unfunded vested benefits, as 
used in subpart B of the regulation, is modified to reflect the 
value of certain claims. To avoid confusion, PBGC proposes to add a 
specific definition of ``unfunded vested benefits'' in each part of 
its multiemployer regulations that uses the term.
---------------------------------------------------------------------------

    The final regulation, like the proposed, adds a new Sec.  4211.6 to 
PBGC's unfunded vested benefits allocation regulation to implement the 
requirements that plan sponsors must disregard adjustable benefit 
reductions and benefit suspensions in allocating unfunded vested 
benefits. Section 4211.6 replaces the approach previously taken by PBGC 
to implement the PPA 2006 ``disregard'' rules by modifying the 
definition of ``nonforfeitable benefit.'' The added MPRA ``disregard'' 
rules made that prior approach difficult to sustain. The final 
regulation, like the proposed, eliminates the special definition of 
``nonforfeitable benefit'' in PBGC's unfunded vested benefits 
allocation regulation and notice, collection, and redetermination of 
withdrawal liability regulation.
    MPRA limited the requirement for a plan sponsor to disregard a 
benefit suspension in determining an employer's withdrawal liability to 
10 years. Under the final regulation, like the proposed, the 
requirement to disregard a benefit suspension applies only for 
withdrawals that occur within the 10 plan years after the end of the 
plan year that includes the effective date of the benefit suspension. 
To calculate withdrawal liability during the 10-year period, a plan 
sponsor disregards the benefit suspension by including the value of the 
suspended benefits in determining the amount of unfunded vested 
benefits allocable to an employer. For example, if a plan has a benefit 
suspension with an effective date within the plan's 2018 plan year, the 
plan sponsor would include the value of the suspended benefits in 
determining the amount of unfunded vested benefits allocable to an 
employer for any withdrawal occurring in plan years 2019 through 2028. 
The plan sponsor would not include the value of the suspended benefits 
in determining the amount of unfunded vested benefits allocable to an 
employer for a withdrawal occurring after the 2028 plan year.
    In cases where a benefit suspension ends and full benefit payments 
resume during the 10-year period following a suspension, the value of 
the suspended

[[Page 1260]]

benefits would continue to be included when calculating withdrawal 
liability until the end of the plan year in which the resumption of 
full benefit payments was required as determined under Department of 
the Treasury guidance, or otherwise occurs.

B. Simplified Methods for Disregarding Adjustable Benefit Reductions 
and Benefit Suspensions (Sec.  4211.16)

    Under section 305(g)(5) of ERISA, PBGC is required to provide 
simplified methods for a plan sponsor to determine withdrawal liability 
when the plan has adjustable benefit reductions or benefit suspensions 
that are required to be disregarded. The final regulation, like the 
proposed, provides a simplified framework for disregarding adjustable 
benefit reductions and benefit suspensions in Sec.  4211.16 of PBGC's 
unfunded vested benefits allocation regulation. A plan sponsor may 
adopt the simplified framework in Sec.  4211.16 to satisfy the 
requirements of section 305(g)(1) of ERISA and Sec.  4211.6 of PBGC's 
unfunded vested benefits allocation regulation, or may choose to use an 
alternative approach to satisfy the requirements of the statutory 
provisions and regulation.
    Under the simplified framework, if a plan has adjustable benefit 
reductions or benefit suspensions, the plan sponsor first calculates an 
employer's withdrawal liability using the plan's withdrawal liability 
method reflecting any adjustable benefit reduction and benefit 
suspension (Sec.  4211.16(b)(1)). The plan sponsor adds the employer's 
proportional share of the value of any adjustable benefit reduction and 
any benefit suspension (Sec.  4211.16(b)(2)). In summary, withdrawal 
liability for a withdrawing employer is based on the sum of the 
following--
    (1) The amount that would be the employer's allocable amount of 
unfunded vested benefits determined in accordance with section 4211 of 
ERISA under the method in use by the plan (based on the value of the 
plan's nonforfeitable benefits reflecting any adjustable benefit 
reduction and any benefit suspension),\8\ and
---------------------------------------------------------------------------

    \8\ The amount of unfunded vested benefits allocable to an 
employer under section 4211 may not be less than zero.
---------------------------------------------------------------------------

    (2) The employer's proportional share of the value of any 
adjustable benefit reduction and the employer's proportional share of 
the value of any suspended benefits.
    Consistent with the proposed rule, under the final rule, this 
amount is required to be calculated before application of the 
adjustments required by section 4201(b)(1) of ERISA, including the de 
minimis reduction and the 20-year cap on payments under section 
4219(c)(1)(B) of ERISA.
    Two commenters asked for clarification on how the rule for the 
application of adjustments required by section 4201(b)(1) of ERISA 
interacts with guidance provided under Technical Update 10-3 (July 15, 
2010) for plan sponsors required to disregard adjustable benefit 
reductions. The commenters stated that plans may have interpreted 
Technical Update 10-3 to adjust for the de minimis reduction before 
adding the proportional share of the adjustable benefit reduction. One 
commenter stated that any clarification of the method provided in 
Technical Update 10-3 should be provided only on a prospective basis 
and that the final rule should provide a safe harbor for plans that may 
have interpreted Technical Update 10-3 differently.
    PBGC agrees that Technical Update 10-3 did not specifically address 
how adjustments for the de minimis reduction and the 20-year cap on 
payments should be applied. PBGC is aware that some plans that adopted 
the simplified method under Technical Update 10-3 make separate 
calculations of an employer's liability under section 4211 of ERISA, 
subject to the adjustments required under section 4201, and an 
employer's liability for adjustable benefit reductions.
    In reviewing the issue in the context of benefit suspensions, PBGC 
concluded that the ``allocable amount of unfunded vested benefits'' 
under section 4201(b)(1) of ERISA, which is calculated before 
adjustments are made, should include the employer's proportional share 
of the value of benefit suspensions required to be disregarded. For 
purposes of providing a simplified framework for adjustable benefit 
reductions and benefit suspensions, PBGC provided in the proposed rule 
that the adjustments required by section 4201(b)(1) of ERISA are made 
after adding the amount that would be the employer's allocable amount 
of unfunded vested benefits determined in accordance with section 4211 
of ERISA and the employer's proportional share of the value of each of 
the benefit reductions and benefit suspensions required to be 
disregarded. Section 4211.16(b) of the final rule is unchanged from the 
proposed rule with respect to the application of the adjustments in 
section 4201(b)(1) of ERISA. In consideration of the comments received, 
PBGC is clarifying that the simplified framework in the final rule 
applies prospectively only and is applicable for withdrawals that occur 
in plan years beginning after the effective date of the final rule.
    One commenter suggested that if the employer's allocable amount 
determined under Sec.  4211.16(a) results in a negative value, a plan 
sponsor should be able to use the negative value to offset the 
employer's allocable share of the value of the adjustable benefit 
reductions and benefit suspensions under Sec.  4211.16(b). The preamble 
to the proposed rule stated that under the simplified framework, the 
amount of unfunded vested benefits allocable to an employer under 
section 4211 of ERISA may not be less than zero. PBGC acknowledges that 
in some cases where precise actuarial calculations are being made 
(i.e., calculations made not using a simplified method), it might be 
appropriate to offset an interim negative value of allocable unfunded 
vested benefits calculated under section 4211 of ERISA against a 
positive allocable value of benefit reductions or benefit suspensions. 
However, because the value of the employer's allocable share of the 
value of adjustable benefit reductions and benefit suspensions under 
the simplified framework are approximations that may be less than the 
value that would be allocated under a non-simplified actuarial 
calculation, PBGC did not allow for an offset of a negative number. In 
the final rule, a sentence is added to the basic rule for the 
simplified framework in Sec.  4211.16(b) to make it clear that the 
amount determined under paragraph (b)(1) may not be a negative number 
to be used as an offset to the employer's allocable share of the value 
of the adjustable benefit reductions and benefit suspensions.
    The same commenter stated that construction-industry plans that 
have no unfunded vested benefits under section 4211 of ERISA should be 
permitted to elect a fresh start for that plan year, even if the plan 
continues to have liability for adjusted benefit reductions and benefit 
suspensions. PBGC agrees with the comment and that a plan sponsor's 
decision to implement a fresh start does not affect the value of 
adjustable benefit reductions and benefit suspensions in calculating 
withdrawal liability. In the final rule, PBGC is clarifying in new 
Sec.  4211.12(d)(3) that in the case of a plan that primarily covers 
employees in the building and construction industry, the plan year 
designated by a plan amendment to implement a fresh start must be a 
plan year for which the plan has no unfunded vested benefits determined 
in accordance with section 4211 of ERISA without regard to Sec.  
4211.6.

[[Page 1261]]

    The commenter also suggested that to the extent adjustable benefit 
reductions are restored, plan sponsors should be able to treat the 
liability for the adjustable benefit reductions as if it had been 
reduced or eliminated. PBGC agrees that, in this circumstance, a plan 
sponsor can offset the present value of restored adjustable benefits 
against the unamortized balance of the adjustable benefit reduction 
under Sec.  4211.16(b)(2). The present value of the restored adjustable 
benefits would be included in the calculation of the allocable amount 
of unfunded vested benefits determined under Sec.  4211.16(b)(1).
    The simplified framework provides simplified methods for 
calculating the employer's proportional share of the value of any 
adjustable benefit reduction and the employer's proportional share of 
the value of any suspended benefits. If a plan has adjustable benefit 
reductions, the plan sponsor may adopt the simplified method discussed 
below to determine the value of the adjustable benefit reductions. If a 
plan has a benefit suspension, the plan sponsor may adopt either the 
static value method or adjusted value method to determine the value of 
the suspended benefits (also discussed below). The contributions for 
the allocation fractions for each of the simplified methods are 
determined in accordance with the rules for disregarding contribution 
increases under Sec.  4211.4 of PBGC's unfunded vested benefits 
allocation regulation (and permissible modifications and 
simplifications under Sec. Sec.  4211.12-4211.15 of PBGC's unfunded 
vested benefits allocation regulation).
    Under the simplified framework, a plan sponsor must include 
liabilities for benefits that have been reduced or suspended in the 
value of vested benefits. But the simplified framework does not require 
a plan sponsor to calculate what plan assets would have been if benefit 
payments had been higher. One commenter asked for the final regulation 
to clarify that, regardless of whether plan sponsors adopt simplified 
methods for disregarding adjustable benefit reductions or benefit 
suspensions, plans are not required to track what plan assets would 
have been absent those reductions or suspensions. PBGC believes that 
generally accepted actuarial principles and practices accommodate the 
adoption of assumptions about quantities (like the amount of such an 
asset reduction) that may not have a material effect on the results of 
the computation. Thus, the issue raised by the commenter is one for 
resolution by the plan actuary.
1. Employer's Proportional Share of the Value of an Adjustable Benefit 
Reduction
    Except as discussed in the preamble, the final regulation, like the 
proposed, incorporates the guidance provided in PBGC Technical Update 
10-3 for disregarding the value of adjustable benefit reductions. 
Technical Update 10-3 explains the simplified method for determining an 
employer's proportional share of the value of adjustable benefit 
reductions. The method applies for any employer withdrawal that occurs 
in any plan year following the plan year in which an adjustable benefit 
reduction takes effect and before the value of the adjustable benefit 
reduction is fully amortized. The method is summarized in the chart in 
section III.B.3. below.
    An employer's proportional share of the value of adjustable benefit 
reductions is determined as of the end of the plan year before 
withdrawal as follows--
[GRAPHIC] [TIFF OMITTED] TR08JA21.010

    The value of the adjustable benefit reductions is determined using 
the same assumptions used to determine unfunded vested benefits for 
purposes of section 4211 of ERISA. The unamortized balance as of a plan 
year is the value as of the end of the year in which the reductions 
took effect (base year), reduced as if that amount were being fully 
amortized in level annual installments over 15 years, at the plan's 
valuation interest rate, beginning with the first plan year after the 
base year.
    The withdrawing employer's allocation fraction is the amount of the 
employer's required contributions over a 5-year period divided by the 
amount of all employers' contributions over the same 5-year period.
    The 5-year period for computing the allocation fraction is the most 
recent 5 plan years ending before the employer's withdrawal. For 
purposes of determining the allocation fraction, the denominator is 
increased by any employer contributions owed with respect to earlier 
periods that were collected in the 5 plan years and decreased by any 
amount contributed by an employer that withdrew from the plan during 
those plan years, or, alternatively, adjusted as permitted under Sec.  
4211.12.
    For calculating the value of adjustable benefit reductions, 
Technical Update 10-3 provides an adjustment if the plan uses the 
rolling-5 method. The value is reduced by outstanding claims for 
withdrawal liability that can reasonably be expected to be collected 
from employers that withdrew as of the end of the plan year before the 
employer's withdrawal. PBGC is not including this adjustment in this 
final rule. The requirement to reduce the unfunded vested benefits by 
the present value of future withdrawal liability payments for 
previously withdrawn employers is part of the rolling-5 calculation, 
and PBGC believes that excluding this adjustment avoids some ambiguity 
that might have led to additional unnecessary calculations and 
recordkeeping.
    One commenter asked for the final regulation to provide an 
additional option for allocating the value of adjustable benefit 
reductions for plans using the presumptive method based on the 5 
consecutive plan years ending before the plan year in which the 
adjustable benefit reduction takes effect. The commenter stated that 
the option would produce an allocation that is more consistent with the 
amount that would be allocated to an employer if the plan did not use a 
simplified allocation method. PBGC considered the comment and has 
determined that the option could be useful for plans using any 
withdrawal liability method under section 4211 of ERISA. Accordingly, 
PBGC has added this option to the simplified framework in Sec.  
4211.16(d).
    Under the added option, the 5-year period for computing the 
allocation fraction is the most recent 5 plan years ending before the 
plan year in which the adjustable benefit reduction takes effect. For 
purposes of determining the allocation fraction, the denominator is 
increased by any employer contributions owed with respect to earlier 
periods that were collected in the 5 plan years and decreased by any 
amount contributed by an employer that withdrew from the plan during 
those plan years, or, alternatively, adjusted as permitted under Sec.  
4211.12.
    For the additional option, the regulation requires an additional

[[Page 1262]]

adjustment to the denominator of the allocation fraction for a plan 
using a method other than the presumptive method or a similar method. 
The denominator after the first year of the 5-year period is decreased 
by the contributions of any employers that withdrew and were unable to 
satisfy their withdrawal liability claims in any year before the 
employer's withdrawal. This adjustment is intended to approximate how a 
withdrawn employer's withdrawal liability is calculated under the 
rolling-5 and modified presumptive methods by fully allocating the 
present value of the suspended benefits to solvent employers. The 
adjustment is not necessary under the presumptive method, as that 
method has a specific adjustment for previously allocated withdrawal 
liabilities that are deemed uncollectible.
2. Employer's Proportional Share of the Value of a Benefit Suspension
a. Static Value Method and Adjusted Value Method
    PBGC's simplified framework provides two simplified methods that a 
plan sponsor may choose between to calculate a withdrawing employer's 
proportional share of the value of a benefit suspension--the static 
value method and the adjusted value method. Both methods apply for any 
employer withdrawal that occurs within the 10 plan years after the end 
of the plan year that includes the effective date of the benefit 
suspension (10-year period). A chart including a comparison of the two 
methods is in section III.B.3. below.
    Under either method, an employer's proportional share of the value 
of a benefit suspension is determined as follows--
[GRAPHIC] [TIFF OMITTED] TR08JA21.011

    Under the static value method, the present value of the suspended 
benefits as of a single calculation date is used for all withdrawals in 
the 10-year period. At the plan sponsor's option, the present value 
could be determined as of: (1) The effective date of the benefit 
suspension (as similar calculations are required as of that date to 
obtain approval of the benefit suspension); or (2) the last day of the 
plan year coincident with or following the date of the benefit 
suspension (as calculations are required as of that date for other 
withdrawal liability purposes). The present value is determined using 
the amount of the benefit suspension as authorized by the Department of 
the Treasury under the plan's application for benefit suspension.
    Under the adjusted value method, the present value of the suspended 
benefits for a withdrawal in the first year of the 10-year period is 
the same as under the static value method. For withdrawals in years 2-
10 of the 10-year period, the value of the suspended benefits is 
determined as of the ``revaluation date,'' the last day of the plan 
year before the employer's withdrawal. The value of the suspended 
benefits is equal to the present value of the benefits not expected to 
be paid in the year of withdrawal or thereafter due to the benefit 
suspension. For example, assume that a calendar year multiemployer plan 
receives final authorization by the Secretary of the Treasury for a 
benefit suspension, effective January 1, 2018, and a contributing 
employer withdraws during the 2022 plan year. The revaluation date is 
December 31, 2021. The value of the suspended benefits is the present 
value of the benefits not expected to be paid after December 31, 2021, 
due to the benefit suspension.
    For both methods, the withdrawing employer's allocation fraction is 
the amount of the employer's required contributions over a 5-year 
period divided by the amount of all employers' contributions over the 
same 5-year period.
    For the static value method, the 5-year period is determined based 
on the most recent 5 plan years ending before the plan year in which 
the benefit suspension takes effect. For the adjusted value method, the 
5-year period is determined based on the most recent 5 plan years 
ending before the employer's withdrawal (which is the same 5-year 
period as is used for the simplified method for adjustable benefit 
reductions).
    For both the static value method and the adjusted value method, the 
denominator of the allocation fraction is increased by any employer 
contributions owed with respect to earlier periods that were collected 
in the applicable 5-year period for the allocation fraction and 
decreased by any amount contributed by an employer that withdrew from 
the plan during those same 5 plan years, or, alternatively, adjusted as 
permitted under Sec.  4211.12 (the same adjustments are made using the 
simplified method for adjustable benefit reductions).
    For the static value method, the regulation requires an additional 
adjustment in the denominator of the allocation fraction for a plan 
using a method other than the presumptive method or similar method. The 
denominator after the first year of the 5-year period is decreased by 
the contributions of any employers that withdrew and were unable to 
satisfy their withdrawal liability claims in any year before the 
employer's withdrawal. This adjustment is intended to approximate how a 
withdrawn employer's withdrawal liability is calculated under the 
rolling-5 and modified presumptive methods by fully allocating the 
present value of the suspended benefits to solvent employers. The 
adjustment is not necessary under the presumptive method, as that 
method has a specific adjustment for previously allocated withdrawal 
liabilities that are deemed uncollectible.
    An example illustrating the simplified framework using the static 
value method for disregarding a benefit suspension is provided in Sec.  
4211.16(e) of PBGC's unfunded vested benefits allocation regulation.
b. Temporary Benefit Suspension
    If a benefit suspension is a temporary suspension of the plan's 
payment obligations as authorized by the Department of the Treasury, 
the present value of the suspended benefits includes the value of the 
suspended benefits only through the ending period of the benefit 
suspension.
    For example, assume that a calendar-year plan has an approved 
benefit suspension effective December 31, 2018, for a 15-year period 
ending December 31, 2033. Effective January 1, 2034, benefits are to be 
restored (prospectively only) to levels not less than those accrued as 
of December 30, 2018, plus benefits accrued after December 31, 2018. 
Employer A withdraws in a complete withdrawal during the 2022 plan 
year. The plan sponsor first determines Employer A's allocable amount 
of unfunded vested benefits under section 4211 of ERISA. That

[[Page 1263]]

amount is the present value of vested benefits as of December 31, 2021, 
including the present value of the vested benefits that are expected to 
be restored effective January 1, 2034. The plan sponsor then determines 
Employer A's proportional share of the value of the suspended benefits. 
The plan uses the static value method. The value of the suspended 
benefits equals the present value, as of December 31, 2018, of the 
benefits accrued as of December 30, 2018, that would otherwise have 
been expected to have been paid, but for the benefit suspension, during 
the 15-year period beginning December 31, 2018, and ending December 31, 
2033. The portion of this present value allocable to Employer A is 
added to the unfunded vested benefits allocable to Employer A under 
section 4211 of ERISA.
c. Partial Withdrawals
    PBGC invited public comment on whether the examples in the proposed 
rule are helpful and whether there are additional types of examples 
that would help plan sponsors with these calculations. Two commenters 
stated that the provided examples are helpful and suggested that PBGC 
provide examples involving partial withdrawals. One commenter asked for 
clarification with examples of the simplified method for adjustable 
benefit reductions as applied to partial withdrawals. Section 4206 of 
ERISA and 29 CFR part 4206 provide rules for determining the amount of 
an employer's liability for a partial withdrawal and, in the case of a 
subsequent withdrawal, for determining the amount of the reduction of 
the employer's liability for the prior partial withdrawal. PBGC 
appreciates the comments requesting examples involving partial 
withdrawals and provides the following example using the simplified 
method in Sec.  4211.16.
    Example: Assume the following:
    (1) The employer's allocable amount of unfunded vested benefits 
determined under section 4211 of ERISA is $1,000,000.
    (2) The employer's proportional share of the value of the 
adjustable benefit reduction is $100,000 (after 8 years of amortization 
of the original amount).
    (3) The employer's proportional share of the value of the benefit 
suspension is $250,000 (the employer's partial withdrawal occurs 3 
years after the effective date of the benefit suspension).
    To calculate the employer's withdrawal liability amount, under 
Sec.  4211.16(b), the amounts in (1) through (3) above are added 
together for a sum of $1,350,000. Based on the sum, a de minimis 
reduction would not apply. The sum is then adjusted in accordance with 
the rules for adjustment of partial withdrawal under section 4206 of 
ERISA. Thus, in this example, the employer's proportional share of the 
value of the adjustable benefit reduction and proportional share of the 
value of the benefit suspension are disregarded in determining the 
withdrawn employer's partial withdrawal liability assessment amount.

----------------------------------------------------------------------------------------------------------------
Allocation Fraction..............       For all three methods, the Allocation Fraction is the amount of the
                                    employer's required contributions over a 5-year period divided by the amount
                                     of all employers' contributions over the same 5-year period. The Allocation
                                      Fraction is determined in accordance with rules to disregard contribution

IV. Regulatory Changes To Reflect Surcharges and Contribution Increases

A. Requirement To Disregard Surcharges and Certain Contribution 
Increases in Determining the Allocation of Unfunded Vested Benefits to 
an Employer (Sec.  4211.4) and the Annual Withdrawal Liability Payment 
Amount (Sec.  4219.3)

    Changes in contributions can affect the calculation of an 
employer's withdrawal liability and annual withdrawal liability payment 
amount. For example, such changes can increase or decrease the 
allocation fraction (discussed above in section I) that is used to 
calculate an employer's withdrawal liability. They can also increase or 
decrease an employer's highest contribution rate used to calculate the 
employer's annual withdrawal liability payment amount (also discussed 
above in section I).
    Required surcharges and certain contribution increases would 
typically result in an increase in an employer's withdrawal liability 
even though unfunded vested benefits are being reduced by the increased 
contributions. Sections 305(g)(2) and (3) of ERISA mitigate the effect 
on withdrawal liability by providing that these surcharges and 
contribution increases that are required or made to enable the plan to 
meet the requirements of the funding improvement plan or rehabilitation 
plan are disregarded in determining contribution amounts used for the 
allocation of unfunded vested benefits and the annual payment amount. 
These sections do not apply for purposes of determining the unfunded 
vested benefits attributable to an employer by a plan using the direct 
attribution method under section 4211(c)(4) of ERISA or a comparable 
method.
    Except as described below the final regulation, like the proposed, 
amends Sec.  4211.4 of PBGC's unfunded vested benefits allocation 
regulation and Sec.  4219.3 of PBGC's notice, collection, and 
redetermination of withdrawal liability regulation to incorporate the 
requirements to disregard these surcharges and contribution increases. 
The final regulation also provides simplified methods for disregarding 
certain contribution increases in the allocation fraction in Sec.  
4211.14 of PBGC's unfunded vested benefits allocation regulation 
(discussed below in section IV.B.). The final rule incorporates the 
disregard rules and simplified methods for contribution increases in 
the allocation methods for merged multiemployer plans provided in 
subpart D of part 4211. PBGC is not providing a simplified method for 
disregarding surcharges in the final rule because we believe that plans 
have been able to apply the statutory requirements without the need for 
a simplified method.
    The provision regarding contribution increases applies to increases 
in the contribution rate or other required contribution increases that 
go into effect during plan years beginning after December 31, 2014.\9\ 
A special rule under section 305(g)(3)(B) of ERISA provides that a 
contribution increase is deemed to be required or made to enable the 
plan to meet the requirement of the funding improvement plan or 
rehabilitation plan, such that the contribution increase is 
disregarded. However, the statute provides that this deeming rule does 
not apply to increases in contribution requirements due to increases in 
levels of work, employment, or periods for which compensation is 
provided, or additional contributions used to provide an increase in 
benefits, including an increase in future benefit accruals, permitted 
by section 305(d)(1)(B) or 305(f)(1)(B). Accordingly, the final 
regulation, with changes from the proposed rule as discussed below, 
provides that these increases are included as contribution increases 
for purposes of determining the allocation fraction and the highest 
contribution rate. In addition, under section 305(g)(4) of ERISA, 
contribution increases are not treated as necessary to satisfy the 
requirement of the funding improvement plan or rehabilitation plan 
after the plan has emerged from critical or endangered status. This 
exception applies only to the determination of the allocation fraction. 
The table below summarizes the statutory exceptions to the rule to 
disregard a contribution increase under section 305(g)(3) and (4) of 
ERISA.

    \9\ The requirement to disregard surcharges for purposes of 
determining an employer's annual withdrawal liability payment is 
effective for surcharges the obligation for which accrues on or 
after December 31, 2014.

------------------------------------------------------------------------

    Sections 4211.4(b)(2)(ii) and 4219.3(a)(2)(ii) of the proposed rule 
reflected an interpretation of the exception under section 305(g)(3) of 
ERISA for additional contributions used to provide an increase in 
benefits. Those sections provided, ``The contribution increase provides 
an increase in benefits, including an increase in future benefit 
accruals, permitted by sections 305(d)(1)(B) or 305(f)(1)(B) of ERISA 
or sections 432(d)(1)(B) or section 432(f)(1)(B) of the Code, and an 
increase in benefit accruals as an integral part of the benefit 
formula.'' The proposed rule required the portion of such contribution 
increase that is attributable to an increase in benefit accruals to be 
determined actuarially and for those contribution increases to be 
included in the calculation of a withdrawn employer's withdrawal 
liability and annual withdrawal liability payment amount.
    Three commenters disagreed with the interpretation provided in the 
proposed rule. They said that the only narrow exception to include 
contribution increases that are used to provide an increase in benefits 
in the calculation of

[[Page 1265]]

withdrawal liability is for increases specifically referred to in 
sections 305(d)(1)(B) or 305(f)(1)(B) of ERISA. These commenters noted 
that plans have excluded all contribution increases under a funding 
improvement plan or rehabilitation plan that became effective in plan 
years beginning after December 31, 2014 from the calculation of 
withdrawal liability. In contrast, two commenters noted that some plans 
have included all contribution increases. One commenter explained that 
some plans use a benefit formula that makes it nearly impossible to 
allocate between what is and is not benefit bearing. Commenters 
objected to the requirement for the portion of the contribution 
increase that is benefit bearing to be determined actuarially. They 
stated that this would cause an increase in administrative costs and 
that plans have used other methods to differentiate between benefit 
bearing and non-benefit bearing portions of contribution increases. For 
example, some plan sponsors classify contribution increases as either 
benefit-bearing (i.e., included in a benefit formula that bases 
accruals on contributions) or supplemental (i.e., excluded from the 
benefit accrual formula). Finally, one commenter asked whether 
certifications under sections 305(d)(1)(B) or 305(f)(1)(B) of ERISA are 
required in the case of a plan with a percentage of contribution 
formula and a contribution increase required by a funding improvement 
plan or rehabilitation plan.
    The final rule modifies proposed Sec.  4211.4(b)(2)(ii) and Sec.  
4219.3(a)(2)(ii) to provide the exception to the disregard rules for a 
contribution increase that provides an increase in benefits by simply 
referring to section 305(g)(3) of ERISA. Specifically, Sec.  
4211.4(b)(2)(ii) and Sec.  4219.3(a)(2)(ii) in the final rule describe 
the exception as applying to contribution increases ``used to provide 
an increase in benefits, including an increase in future benefit 
accruals, permitted by section (d)(1)(B) or (f)(1)(B) of ERISA.'' A 
plan sponsor is required to include such contribution increases in the 
calculation of a withdrawn employer's withdrawal liability and annual 
withdrawal liability payment amount. The final rule does not provide 
further interpretation. Commenters raised interpretive issues about 
sections 305(g)(3), 305(d)(1)(B), and 305(f)(1)(B) of ERISA that are 
under the jurisdiction of the Department of the Treasury as well as 
plan benefit design issues that require further study. PBGC is 
continuing to examine these issues with the Department of the Treasury 
and, if appropriate, will issue additional guidance.

B. Simplified Methods for Disregarding Certain Contribution Increases 
in the Allocation Fraction (Sec.  4211.14)

    The allocation fraction that is used in the presumptive, modified 
presumptive, and rolling-5 methods to determine an employer's 
proportional share of unfunded vested benefits is discussed above in 
section I. The final regulation adds a new Sec.  4211.14 to the 
unfunded vested benefits allocation regulation to provide a choice of 
one simplified method for the numerator and two simplified methods for 
the denominator of the allocation fraction. A plan sponsor may adopt 
the simplified methods in Sec.  4211.14 to satisfy the requirements of 
section 305(g)(3) of ERISA and Sec.  4211.4(b)(2) to disregard 
contribution increases in determining the allocation of unfunded vested 
benefits, or may choose an alternative approach that satisfies the 
requirements of the statutory provisions and regulations. A plan 
amended to use one or more of the simplified methods in this section 
must also apply the rules to disregard surcharges under new Sec.  
4211.4.
    One commenter asked that the final regulation allow plans using the 
direct attribution method to use the simplified methods for 
contribution increases if use of such methods is otherwise reasonable. 
The disregard rules for contribution increases under section 
305(g)(3)(A) of ERISA do not apply for purposes of determining the 
unfunded vested benefits attributable to an employer by a plan using 
the direct attribution method under section 4211(c)(4) of ERISA or a 
comparable method. PBGC's authority to provide simplified methods under 
section 305(g)(5) of ERISA is limited to methods for applying the 
disregard rules in determining withdrawal liability and payment 
amounts. PBGC therefore did not incorporate the commenter's requested 
change in the final rule.
1. Determining the Numerator Using the Employer's Plan Year 2014 
Contribution Rate
    Under the simplified method for determining the numerator of the 
allocation fraction, a plan sponsor bases the calculation on an 
employer's contribution rate as of the last day of each plan year 
(rather than applying a separate calculation for contribution increases 
that occur in the middle of a plan year). The plan sponsor starts with 
the employer's contribution rate as of the ``employer freeze date.'' 
The employer freeze date is the date that is the later of the last day 
of the first plan year that ends on or after December 31, 2014 
(December 31, 2014 for a calendar year plan) and the last day of the 
plan year the employer first contributes to the plan. If, after the 
employer freeze date, the plan has a contribution rate increase that 
provides an increase in benefits so that the contribution increase is 
included, that rate increase is added to the contribution rate for each 
target year for which the rate increase is effective. Under the method, 
the product of the employer freeze date contribution rate (increased in 
accordance with the prior sentence, if applicable) and the withdrawn 
employer's contribution base units in each plan year (``target year'') 
are used for the numerator and the comparable amount determined for 
each employer is included in the denominator (described in B.2 below), 
unless the plan sponsor uses the proxy group method for determining the 
denominator (described in B.3 below). If there is more than one 
contribution rate or basis for calculating contribution base units, the 
calculations can be performed separately for each contribution rate or 
contribution base sub-group and then summed. An example illustrating 
the simplified method for disregarding certain contributions in 
determining the numerator using the employer's plan year 2014 
contribution rate is provided in the appendix to part 4211.
2. Determining the Denominator Using Each Employer's Plan Year 2014 
Contribution Rate
    Under the first simplified method for determining the denominator 
of the allocation fraction, a plan sponsor applies the same principles 
as for the simplified method above for determining the numerator of the 
allocation fraction. The plan sponsor holds steady each employer's 
contribution rate as of the employer freeze date, except for 
contribution increases that provide benefit increases as described 
above. For each employer, the plan sponsor multiplies this rate by each 
employer's contribution base units in each target year.
3. Determining the Denominator Using the Proxy Group Method
    Plans frequently offer multiple contribution schedules under a 
funding improvement plan or rehabilitation plan, which may have varying 
contribution rate increases. Under these and other circumstances, it 
could be administratively burdensome for plans to determine the exact 
amount of an employer's contributions--excluding contributions required 
to be disregarded

[[Page 1266]]

in determining withdrawal liability--to include in the denominator of 
the allocation fraction. Accordingly, the regulation provides a second 
simplified method for determining contributions in the denominator. 
This method, called the proxy group method, is available for plans that 
are amended to provide for use of the method. The method permits the 
contributions included in the denominator of the allocation fraction 
for a plan year to be based on an amount calculated for ``proxy'' 
representatives of the plan's contributing employers.
    A commenter noted that different schedules and rate increases may 
apply to different categories of employees of a single employer--for 
example, because different collective bargaining agreements apply to 
different categories of the employer's employees. In response, the 
final regulation permits a single employer whose employees have highly 
dissimilar contribution histories to be treated as two or more 
employers with more uniform contribution histories in applying the 
proxy group method.
    Under the proxy group method, employers are grouped in rate history 
groups, based on similarity of contribution histories (or same 
percentage increases in contributions from year to year). 
(Notwithstanding the diversity of contribution histories, rate history 
groups may be limited to 10.) Representative employers, representing at 
least 10 percent of active plan participants, are drawn from rate 
history groups to form the proxy group. ``Adjusted contributions''--
excluding contribution rate increases that must be disregarded for 
withdrawal liability purposes--are determined for employers in the 
proxy group; then for rate history groups, based on the adjusted 
contributions of employers in each rate history group; and finally for 
the plan, based on the adjusted contributions of rate history groups 
represented in the proxy group. The plan's adjusted contributions form 
the denominator of the withdrawal liability allocation fraction.
    As with other simplified methods, only contribution rates in effect 
at year end need be considered.
    The process of forming rate history groups may be illustrated by 
the following examples.
    Example 1. Employers in Plan A had twelve different contribution 
rates at the start of the rehabilitation period, as shown in the 
following table:

----------------------------------------------------------------------------------------------------------------
                                                     Column 1        Column 2        Column 3        Column 4
----------------------------------------------------------------------------------------------------------------
Row 1...........................................           $2.00           $2.25           $2.50           $2.75
Row 2...........................................            3.00            3.25            3.50            3.75
Row 3...........................................            4.00            4.25            4.50            4.75
----------------------------------------------------------------------------------------------------------------

    The rehabilitation plan requires increases of $0.50 per hour per 
year for employers in Row 1, $0.75 per hour per year for those in Row 
2, and $1.00 per hour per year for those in Row 3. All collective 
bargaining agreements are amended by the beginning of 2015, and the 
increases are effective as of the beginning of 2015. The following 
table shows the percentage rates of increase in contribution rates at 
year-end 2015 compared with year-end 2014:

----------------------------------------------------------------------------------------------------------------
                                                     Column 1        Column 2        Column 3        Column 4
                                                     (percent)       (percent)       (percent)       (percent)
----------------------------------------------------------------------------------------------------------------
Row 1...........................................           25.00           22.22           20.00           18.18
Row 2...........................................           25.00           23.08           21.43           20.00
Row 3...........................................           25.00           23.53           22.22           21.05
----------------------------------------------------------------------------------------------------------------

    Since the increase rates for employers in Column 1 are the same, 
the plan can put those employers in one rate group. Similarly, 
employers in Column 2 have relatively uniform rates and can be grouped 
together, and likewise for those in Columns 3 and those in Column 4. 
Alternatively, employers in Columns 3 and 4 of Row 1 could be grouped 
together with those in Column 4 of Row 2; and employers in Columns 3 
and 4 of Row 3 could be grouped together with those in Column 3 of Row 
2.
    Example 2. Plan B has many employers and many contribution rate 
schedules. Contributions change between 2010 and 2021 as follows:
    Under the default schedule, there are one-time increases of 50 
percent in 2010 for employers in Category A (defaults occurring in 
2010); 55 percent in 2011 for employers in Category B (defaults 
occurring in 2011); and 60 percent in 2012 for employers in Category C 
(defaults occurring in 2012). For employers in Category D through Y, 
which have negotiated new collective bargaining agreements, increases 
are as shown in the following table:

------------------------------------------------------------------------

------------------------------------------------------------------------

    The annual percentage increases for employers in Category D through 
Y are cumulative. Thus, if an employer's contribution rate for the 
second quarter of 2010 in Category F was $100.00, its contributions for 
2010, 2011, and 2012 would be $104.00, $108.16, and $112.49 (based on 
rates in effect at year-end).
    Appropriate rate history groups for 2015 through 2021 could be as 
follows:

------------------------------------------------------------------------
            Rate history group              Employer categories in group
------------------------------------------------------------------------
1........................................  A, B, C.

6........................................  R, S.
7........................................  T, U.
8........................................  V, W.
9........................................  X.
10.......................................  Y.
------------------------------------------------------------------------

    These groupings take advantage of the provision that no more than 
ten rate history groups need be provided for.
    In response to a comment requesting more flexibility in the 
determination of proxy groups, the final regulation omits the 
requirement that the proxy group employers be named in the plan. 
However, the regulation requires that there be consistency from year to 
year in the composition of both the proxy group and rate history 
groups, with certain exceptions. The intent is to keep these groups 
generally unchanged but to permit changes in their make-up to 
accommodate changes in circumstances such as contribution histories and 
employer withdrawals.
    Employers contributing under the same rate schedule would typically 
be in the same rate history group, and a change in the rate schedule 
would typically not change the composition of the rate history group, 
because the rate histories of all employers in the group would be 
similarly affected. For example, suppose all the employers under a rate 
schedule are in the same rate history group, and the rate schedule 
changes. This would typically not change the composition of the rate 
history group, because the rate histories of all employers in the group 
would be similarly affected.
    In the same vein, employers with disparate rate histories would 
typically be in different rate history groups, and the fact that they 
became covered by the same rate schedule would not typically place them 
in the same rate history group because their rate histories would 
remain different. For example, suppose two employers with disparate 
rate histories are in different rate history groups and become covered 
by the same rate schedule. This would not typically place them in the 
same rate history group because their rate histories would remain 
different.
    On the other hand, if two employers in a rate history group moved 
to a different rate schedule, their rate histories would no longer 
match those of the other employers in the group. Depending on 
circumstances, this change might result in the formation of a new rate 
history group that (if it represented more than 5 percent of active 
participants) would require representation in the proxy group.
    For proxy group employers, adjusted contributions for the plan year 
are determined by multiplying each employer's contribution base units 
for the plan year by what would have been the employer's contribution 
rate excluding contribution rate increases that are required to be 
disregarded in determining withdrawal liability.
    Determining adjusted contributions for rate history groups is a 
two-step process. First, an adjustment factor is determined for the 
plan year for each rate history group represented in the proxy group of 
employers. This adjustment factor equals the sum of the adjusted 
contributions for the plan year for all employers in the rate history 
group that are in the proxy group, divided by the sum of those 
employers' actual total contributions for the plan year. Second, the 
adjustment factor for the year for each rate history group is 
multiplied by the contributions for the year of all employers in the 
rate history group (both proxy group members and non-members) to 
determine the adjusted contributions for the rate history group for the 
year.
    Finally, the same steps are performed to determine adjusted 
contributions at the plan level. The sum of the adjusted contributions 
for all the rate history groups represented in the proxy group is 
divided by the sum of the actual contributions for the employers in 
those rate history groups, and the resulting adjustment factor for the 
plan is multiplied by the plan's total contributions for the plan year, 
including contributions by employers in small rate history groups not 
represented in the proxy group. The result--the adjusted contributions 
for the whole plan--is the amount of contributions for the plan year 
that may be used to determine the denominator for the allocation 
fraction under the proxy group method.
    This process weights contributors by the size of their 
contributions. Heavy contributors' rates have a greater impact on the 
adjusted contributions than light contributors' rates.
    A commenter asked that relief be provided for cases where 
information needed to determine adjusted contributions is unavailable. 
In response, PBGC has added a provision addressing situations where 
total contributions for a rate history group or a plan are unavailable 
to calculate adjusted contributions. In such situations, total 
contributions may be estimated by multiplying each contribution rate 
times the relevant projected contribution base units and adding all the 
results.
    An example illustrating the simplified method for disregarding 
certain contributions in determining the denominator of the allocation 
fraction using the proxy group method is provided in the appendix to 
part 4211.

C. Simplified Methods After Plan Is No Longer in Endangered or Critical 
Status

    As noted above in section IV.A., changes in contributions can 
affect the calculation of an employer's withdrawal

[[Page 1268]]

liability and annual withdrawal liability payment amount. Once a plan 
is no longer in endangered or critical status, the ``disregard'' rules 
for contribution increases change. Under section 305(g)(4) of ERISA, 
plan sponsors are required to: (1) Include contribution increases in 
determining the allocation fraction used to calculate withdrawal 
liability under section 4211 of ERISA; and (2) continue to disregard 
contribution increases in determining the highest contribution rate 
used to calculate the annual withdrawal liability payment amount under 
section 4219(c) of ERISA, as follows:

------------------------------------------------------------------------
Allocation Fraction (section 4211   A plan sponsor is required to

                                     expiration date of the collective
                                     bargaining agreement in effect when
                                     a plan is no longer in endangered
                                     or critical status.
Highest Contribution Rate (section  A plan sponsor is required to
 4219(c) of ERISA).                  continue disregarding contribution
                                     increases that applied for plan
                                     years during which the plan was in
                                     endangered or critical status.
------------------------------------------------------------------------

    The final regulation, like the proposed, amends Sec.  4211.4 of 
PBGC's unfunded vested benefits allocation regulation and Sec.  4219.3 
of PBGC's notice, collection, and redetermination of withdrawal 
liability regulation to incorporate the requirements for contribution 
increases when a plan is no longer in endangered or critical status. 
The final regulation also provides simplified methods required by 
section 305(g)(5) of ERISA that a plan sponsor could adopt to satisfy 
the requirements of section 305(g)(4).
1. Including Contribution Increases in Determining the Allocation of 
Unfunded Vested Benefits (Sec.  4211.15)
    The rule to begin including contribution increases for purposes of 
determining withdrawal liability is based, in part, on when a plan's 
collective bargaining agreements expire. Because plans may operate 
under numerous collective bargaining agreements with varying expiration 
dates, it could be burdensome for a plan sponsor to calculate the 
amount contributed by employers over the 5-year periods used for the 
denominators of the plan's allocation method. The plan sponsor would 
have to make a year-by-year determination of whether contribution 
increases should be included or disregarded in the denominators 
relative to collective bargaining agreements expiring in each 
applicable year. The final regulation adds a new Sec.  4211.15 to 
PBGC's unfunded vested benefits allocation regulation to provide two 
alternative simplified methods that a plan sponsor could adopt for 
determining the denominators in the allocation fractions when the plan 
is no longer in endangered or critical status.
    Under the first simplified method, a plan sponsor could adopt a 
rule that contribution increases previously disregarded are included in 
the allocation fraction as of the expiration date of the first 
collective bargaining agreement requiring contributions that expires 
after the plan's emergence from endangered or critical status. If the 
plan sponsor adopts this rule, then for any withdrawals after the 
applicable expiration date, the plan sponsor would include the total 
amount contributed by employers for plan years included in the 
denominator of the allocation fraction determined in accordance with 
section 4211 of ERISA under the method in use by the plan. This would 
relieve plan sponsors of the burden of a year-by-year determination of 
whether contribution increases should be included or disregarded in the 
denominator under the plan's allocation method relative to collective 
bargaining agreements expiring in that year. An example illustrating 
this simplified method is provided in Sec.  4211.15(c) of PBGC's 
unfunded vested benefits allocation regulation.
    Under the second simplified method, a plan sponsor could adopt a 
rule that contribution increases previously disregarded are included in 
calculating withdrawal liability for any employer withdrawal that 
occurs after the first full plan year after a plan is no longer in 
endangered or critical status, or if later, the plan year including the 
expiration date of the first collective bargaining agreement requiring 
plan contributions that expires after the plan's emergence from 
endangered or critical status.
    The final regulation also provides that, for purposes of these 
simplified methods, an ``evergreen contract'' that continues until the 
collective bargaining parties elect to terminate the agreement has a 
termination date that is the earlier of--
    (1) The termination of the agreement by decision of the parties.
    (2) The beginning of the third plan year following the plan year in 
which the plan is no longer in endangered or critical status.
    PBGC invited public comment on other simplified methods that a plan 
operating under numerous collective bargaining agreements with varying 
expiration dates might use to satisfy the requirement in section 
305(g)(4) of ERISA that, as of the expiration date of the first 
collective bargaining agreement requiring plan contributions that 
expires after a plan is no longer in endangered or critical status, the 
allocation fraction must include contribution increases that were 
previously disregarded. Two commenters supported PBGC's proposed 
simplified method as a reasonable way to satisfy the requirements of 
section 305(g)(4) of ERISA.
2. Continuing To Disregard Contribution Increases in Determining the 
Highest Contribution Rate (Sec.  4219.3)
    The rule for determining the highest contribution rate requires a 
plan sponsor of a plan that is no longer in endangered or critical 
status to continue to disregard increases in the contribution rate that 
applied for plan years during which the plan was in endangered or 
critical status. Because an employer's highest contribution rate is 
determined over the 10 plan years ending with the year of withdrawal, 
applying the rule would require a year-by-year determination of whether 
contribution increases should be included or disregarded. The final 
regulation adds a new Sec.  4219.3 to PBGC's notice, collection, and 
redetermination of withdrawal liability regulation to provide a 
simplified method that a plan sponsor could adopt for determining the 
highest contribution rate.
    The simplified method provides that, for a plan that is no longer 
in endangered or critical status, the highest contribution rate for 
purposes of section 4219(c) of ERISA is the greater of--
    (1) The employer's contribution rate in effect, for a calendar year 
plan, as of December 31, 2014, and for other plans, the last day of the 
plan year that ends on or after December 31, 2014, plus any 
contribution increases occurring after that date and before the 
employer's withdrawal that must be included in

[[Page 1269]]

determining the highest contribution rate under section 305(g)(3) of 
ERISA, or
    (2) The highest contribution rate for any plan year after the plan 
year that includes the expiration date of the first collective 
bargaining agreement of the withdrawing employer requiring plan 
contributions that expires after the plan is no longer in endangered or 
critical status, or, if earlier, the date as of which the withdrawing 
employer renegotiated a contribution rate effective after a plan is no 
longer in endangered or critical status.
    An example illustrating this simplified method is provided in Sec.  
4219.3 of PBGC's notice, collection, and redetermination of withdrawal 
liability regulation. PBGC received two comments about the simplified 
method provided in Sec.  4219.3. One commenter asked for clarification 
about the contribution rate that should be included in determining the 
highest contribution rate if an employer withdraws after its collective 
bargaining agreement expires, but before a new collective bargaining 
agreement is adopted. Another commenter stated that under the 
simplified method, if the plan year ends soon after the expiration date 
of the collective bargaining agreement, a higher contribution rate 
could be imposed on an employer than the plan's later negotiated 
contribution rate. PBGC agrees that this could occur under the 
simplified method if the bargaining parties do not reach agreement by 
the plan year after the plan year that includes the expiration date of 
the first collective bargaining agreement of the withdrawing employer 
requiring plan contributions that expires after the plan is no longer 
in endangered or critical status.
    A commenter suggested that a grace period could be provided after 
the expiration date of the collective bargaining agreement, such as 180 
days, during which the higher rate would not apply if it had not been 
agreed to in collective bargaining. While in many cases collective 
bargaining agreements are not renegotiated until after the expiration 
date of the collective bargaining agreement, PBGC believes that the 
collective bargaining parties will generally have time to resolve the 
scenario described by the commenter before a plan emerges from 
endangered or critical status. In addition, PBGC's simplified method 
already extends the disregard period beyond the highest contribution 
rate ``for plan years during which the plan was in endangered or 
critical status'' to include the period through the end of the plan 
year after the plan year that includes the expiration date of the first 
collective bargaining agreement that expires after the plan is no 
longer in endangered or critical status. Therefore, PBGC did not adopt 
the commenter's suggestion to change the simplified method in the final 
rule.

V. Compliance With Rulemaking Guidelines

Executive Orders 12866, 13563, and 13771

    The Office of Management and Budget (OMB) has determined that this 
rulemaking is not a ``significant regulatory action'' under Executive 
Order 12866 and Executive Order 13771. The rule provides simplified 
methods, as required by section 305(g)(5) of ERISA, to determine 
withdrawal liability and payment amounts, which multiemployer plan 
sponsors may choose, but are not required, to adopt. Accordingly, this 
final rule is exempt from Executive Order 13771 and OMB has not 
reviewed the rule under Executive Order 12866.
    Executive Orders 12866 and 13563 direct agencies to assess all 
costs and benefits of available regulatory alternatives and, if 
regulation is necessary, to select regulatory approaches that maximize 
net benefits (including potential economic, environmental, and public 
health and safety effects, distributive impacts, and equity). E.O. 
13563 emphasizes retrospective review of regulations, harmonizing 
rules, and promoting flexibility.
    Although this is not a significant regulatory action under 
Executive Order 12866, PBGC has examined the economic implications of 
this final rule and has concluded that the amendments providing 
simplified methods for plan sponsors to comply with the statutory 
requirements will reduce costs for multiemployer plans by approximately 
$1,476,000. Based on 2016 data, there are about 450 plans that are in 
endangered or critical status.\10\ PBGC estimates that a portion of 
these plans using the simplified methods under the final rule will have 
administrative savings, as follows:

    Total savings...............................................  ..............  ..............       1,476,000
----------------------------------------------------------------------------------------------------------------

    PBGC invited public comment on the expected savings on actuarial 
calculations and other costs using the simplified methods. A commenter 
noted that expected savings on actuarial calculations and plan 
administration

[[Page 1270]]

will vary greatly from plan to plan based on the plan's industry, 
benefit formula, and other factors. Three commenters stated that the 
requirement in the proposed rule that the portion of contribution 
increases that is funding an increase in future benefit accruals be 
determined actuarially would cause an increase in administrative costs. 
As discussed above in section IV.A. of the preamble, the final rule 
does not adopt this provision.

Regulatory Flexibility Act

    The Regulatory Flexibility Act imposes certain requirements with 
respect to rules that are subject to the notice and comment 
requirements of section 553(b) of the Administrative Procedure Act and 
that are likely to have a significant economic impact on a substantial 
number of small entities. Unless an agency determines that a rule is 
not likely to have a significant economic impact on a substantial 
number of small entities, section 604 of the Regulatory Flexibility Act 
requires that the agency present a final regulatory flexibility 
analysis at the time of the publication of the final regulation 
describing the impact of the rule on small entities and steps taken to 
minimize the impact. Small entities include small businesses, 
organizations, and governmental jurisdictions.
    For purposes of the Regulatory Flexibility Act requirements with 
respect to this final rule, PBGC considers a small entity to be a plan 
with fewer than 100 participants. This is substantially the same 
criterion PBGC uses in other regulations \11\ and is consistent with 
certain requirements in title I of ERISA \12\ and the Code,\13\ as well 
as the definition of a small entity that the Department of Labor has 
used for purposes of the Regulatory Flexibility Act.\14\
---------------------------------------------------------------------------

    \11\ See, e.g., special rules for small plans under part 4007 
(Payment of Premiums).
    \12\ See, e.g., section 104(a)(2) of ERISA, which permits the 
Secretary of Labor to prescribe simplified annual reports for 
pension plans that cover fewer than 100 participants.
    \13\ See, e.g., section 430(g)(2)(B) of the Code, which permits 
plans with 100 or fewer participants to use valuation dates other 
than the first day of the plan year.
    \14\ See, e.g., DOL's final rule on Prohibited Transaction 
Exemption Procedures, 76 FR 66637, 66644 (Oct. 27, 2011).
---------------------------------------------------------------------------

    Thus, PBGC believes that assessing the impact of the proposed 
regulation on small plans is an appropriate substitute for evaluating 
the effect on small entities. The definition of small entity considered 
appropriate for this purpose differs, however, from a definition of 
small business based on size standards promulgated by the Small 
Business Administration (13 CFR 121.201) pursuant to the Small Business 
Act. PBGC therefore requested comments on the appropriateness of the 
size standard used in evaluating the impact on small entities of the 
proposed amendments. PBGC did not receive any such comments.
    On the basis of its definition of small entity, PBGC certifies 
under section 605(b) of the Regulatory Flexibility Act (5 U.S.C. 601 et 
seq.) that the amendments in this final rule will not have a 
significant economic impact on a substantial number of small entities. 
Based on data for recent premium filings, PBGC estimates that only 38 
plans of the approximately 1,400 plans covered by PBGC's multiemployer 
program are small plans, and that only about 14 of those plans will be 
impacted by this final rule. Furthermore, plan sponsors may, but are 
not required to, use the simplified methods under the final rule. As 
shown above, plans that use the simplified methods will have 
administrative savings. The final rule will not impose costs on plans. 
Accordingly, as provided in section 605 of the Regulatory Flexibility 
Act (5 U.S.C. 601 et seq.), sections 603 and 604 do not apply.

14. Revise Sec.  4211.4 to read as follows:


Sec.  4211.4  Contributions for purposes of the numerator and 
denominator of the allocation fractions.

    (a) In general. Subject to paragraph (b) of this section, each of 
the allocation fractions used in the presumptive, modified presumptive 
and rolling-5 methods is based on contributions that certain employers 
have made to the plan for a 5-year period.
    (1) The numerator of the allocation fraction, with respect to a 
withdrawing employer, is based on the ``sum of the contributions 
required to be made'' or the ``total amount required to be 
contributed'' by the employer for the specified period.
    (2) The denominator of the allocation fraction is based on 
contributions that certain employers have made to the plan for a 
specified period.
    (b) Disregarding surcharges and contribution increases. For each of 
the allocation fractions used in the presumptive, modified presumptive 
and rolling-5 methods in determining the allocation of unfunded vested 
benefits to an employer, a plan in endangered or critical status must 
disregard:
    (1) Surcharge. Any surcharge under section 305(e)(7) of ERISA and 
section 432(e)(7) of the Code.
    (2) Contribution increase. Any increase in the contribution rate or 
other increase in contribution requirements that goes into effect 
during plan years beginning after December 31, 2014, so that a plan may 
meet the requirements of a funding improvement plan under section 
305(c) of ERISA and section 432(c) of the Code or a rehabilitation plan 
under section 305(e) of ERISA and 432(e) of the Code, except to the 
extent that one of the following exceptions applies pursuant to section 
305(g)(3) or (4) of ERISA and section 432(g)(3) or (4) of the Code:
    (i) The increases in contribution requirements are due to increased 
levels of work, employment, or periods for which compensation is 
provided.
    (ii) The additional contributions are used to provide an increase 
in benefits, including an increase in future benefit accruals, 
permitted by section 305(d)(1)(B) or (f)(1)(B) of ERISA and section 
432(d)(1)(B) or (f)(1)(B) of the Code.
    (iii) The withdrawal occurs on or after the expiration date of the 
employer's collective bargaining agreement in effect in the plan year 
the plan is no longer in endangered or critical status, or, if earlier, 
the date as of which the employer renegotiates a contribution rate 
effective after the plan year the plan is no longer in endangered or 
critical status.
    (c) Simplified methods. See Sec. Sec.  4211.14 and 4211.15 for

15. Add Sec.  4211.6 to read as follows:


Sec.  4211.6  Disregarding benefit reductions and benefit suspensions.

    (a) In general. A plan must disregard the following nonforfeitable 
benefit reductions and benefit suspensions in determining a plan's 
nonforfeitable benefits for purposes of determining an employer's 
withdrawal liability under section 4201 of ERISA:
    (1) Adjustable benefit. A reduction to adjustable benefits under 
section 305(e)(8) of ERISA and section 432(e)(8) of the Code.
    (2) Lump sum. A benefit reduction arising from a restriction on 
lump sums or other benefits under section 305(f) of ERISA and section 
432(f) of the Code.
    (3) Benefit suspension. A benefit suspension under section 
305(e)(9) of ERISA and section 432(e)(9) of the Code, but only for 
withdrawals not more than 10 years after the end of the plan year in 
which the benefit suspension takes effect.
    (b) Simplified methods. See Sec.  4211.16 for simplified methods 
for meeting the requirements of this section.

16. Revise Sec.  4211.11 to read as follows:


Sec.  4211.11  Plan sponsor adoption of modifications and simplified 
methods.

    (a) General rule. A plan sponsor, other than the sponsor of a plan 
that primarily covers employees in the building and construction 
industry, may adopt by amendment, without the approval of PBGC, any of 
the statutory allocation methods and any of the modifications and 
simplified methods set forth in Sec. Sec.  4211.12 through 4211.16.
    (b) Building and construction industry plans. The plan sponsor of a 
plan that primarily covers employees in the building and construction 
industry may adopt by amendment, without the

[[Page 1272]]

approval of PBGC, any of the modifications to the presumptive rule and 
simplified methods set forth in Sec.  4211.12 and Sec. Sec.  4211.14 
through 4211.16.

0
17. Revise Sec.  4211.12 to read as follows:


Sec.  4211.12  Modifications to the presumptive, modified presumptive, 
and rolling-5 methods.

    (a) Disregarding certain contribution increases. A plan amended to 
use the modifications in this section must apply the rules to disregard 
surcharges and contribution increases under Sec.  4211.4. A plan 
sponsor may amend a plan to incorporate the simplified methods in 
Sec. Sec.  4211.14 and 4211.15 to fulfill the requirements of Sec.  
4211.4 with the modifications in this section if done consistently from 
year to year.
    (b) Changing the period for counting contributions. A plan sponsor 
may amend a plan to modify the denominators in the presumptive, 
modified presumptive and rolling-5 methods in accordance with one of 
the alternatives described in this paragraph (b). Any amendment adopted 
under this paragraph (b) must be applied consistently to all plan 
years. Contributions counted for 1 plan year may not be counted for any 
other plan year. If a contribution is counted as part of the ``total 
amount contributed'' for any plan year used to determine a denominator, 
that contribution may not also be counted as a contribution owed with 
respect to an earlier year used to determine the same denominator, 
regardless of when the plan collected that contribution.
    (1) A plan sponsor may amend a plan to provide that ``the sum of 
all contributions made'' or ``total amount contributed'' for a plan 
year means the amount of contributions that the plan actually received 
during the plan year, without regard to whether the contributions are 
treated as made for that plan year under section 304(b)(3)(A) of ERISA 
and section 431(b)(3)(A) of the Code.
    (2) A plan sponsor may amend a plan to provide that ``the sum of 
all contributions made'' or ``total amount contributed'' for a plan 
year means the amount of contributions actually received during the 
plan year, increased by the amount of contributions received during a 
specified period of time after the close of the plan year not to exceed 
the period described in section 304(c)(8) of ERISA and section 
431(c)(8) of the Code and regulations thereunder.
    (3) A plan sponsor may amend a plan to provide that ``the sum of 
all contributions made'' or ``total amount contributed'' for a plan 
year means the amount of contributions actually received during the 
plan year, increased by the amount of contributions accrued during the 
plan year and received during a specified period of time after the 
close of the plan year not to exceed the period described in section 
304(c)(8) of ERISA and section 431(c)(8) of the Code and regulations 
thereunder.
    (c) Excluding contributions of significant withdrawn employers. 
Contributions of certain withdrawn employers are excluded from the 
denominator in each of the fractions used to determine a withdrawing 
employer's share of unfunded vested benefits under the presumptive, 
modified presumptive and rolling-5 methods. Except as provided in 
paragraph (c)(1) of this section, contributions of all employers that 
permanently cease to have an obligation to contribute to the plan or 
permanently cease covered operations before the end of the period of 
plan years used to determine the fractions for allocating unfunded 
vested benefits under each of those methods (and contributions of all 
employers that withdrew before September 26, 1980) are excluded from 
the denominators of the fractions.
    (1) The plan sponsor of a plan using the presumptive, modified 
presumptive or rolling-5 method may amend the plan to provide that only 
the contributions of significant withdrawn employers are excluded from 
the denominators of the fractions used in those methods.
    (2) For purposes of this paragraph (c), ``significant withdrawn 
employer'' means--
    (i) An employer to which the plan has sent a notice of withdrawal 
liability under section 4219 of ERISA; or
    (ii) A withdrawn employer that in any plan year used to determine 
the denominator of a fraction contributed at least $250,000 or, if 
less, 1 percent of all contributions made by employers for that year.
    (3) If a group of employers withdraw in a concerted withdrawal, the 
plan sponsor must treat the group as a single employer in determining 
whether the members are significant withdrawn employers under paragraph 
(c)(2) of this section. A ``concerted withdrawal'' means a cessation of 
contributions to the plan during a single plan year--
    (i) By an employer association;
    (ii) By all or substantially all of the employers covered by a 
single collective bargaining agreement; or
    (iii) By all or substantially all of the employers covered by 
agreements with a single labor organization.
    (d) ``Fresh start'' rules under presumptive method. (1) The plan 
sponsor of a plan using the presumptive method (including a plan that 
primarily covers employees in the building and construction industry) 
may amend the plan to provide that--
    (i) A designated plan year ending after September 26, 1980, will 
substitute for the plan year ending before September 26, 1980, in 
applying section 4211(b)(1)(B), section 4211(b)(2)(B)(ii)(I), section 
4211(b)(2)(D), section 4211(b)(3), and section 4211(b)(3)(B) of ERISA; 
and
    (ii) Plan years ending after the end of the designated plan year in 
paragraph (d)(1)(i) of this section will substitute for plan years 
ending after September 25, 1980, in applying section 4211(b)(1)(A), 
section 4211(b)(2)(A), and section 4211(b)(2)(B)(ii)(II) of ERISA.
    (2) A plan amendment made pursuant to paragraph (d)(1) of this 
section must provide that the plan's unfunded vested benefits for plan 
years ending after the designated plan year are reduced by the value of 
all outstanding claims for withdrawal liability that can reasonably be 
expected to be collected from employers that had withdrawn from the 
plan as of the end of the designated plan year.
    (3) In the case of a plan that primarily covers employees in the 
building and construction industry, the plan year designated by a plan 
amendment pursuant to paragraph (d)(1) of this section must be a plan 
year for which the plan has no unfunded vested benefits determined in 
accordance with section 4211 of ERISA without regard to Sec.  4211.6.
    (e) ``Fresh start'' rules under modified presumptive method. (1) 
The plan sponsor of a plan using the modified presumptive method may 
amend the plan to provide--
    (i) A designated plan year ending after September 26, 1980, will 
substitute for the plan year ending before September 26, 1980, in 
applying section 4211(c)(2)(B)(i) and section 4211(c)(2)(B)(ii)(I) and 
(II) of ERISA; and
    (ii) Plan years ending after the end of the designated plan year 
will substitute for plan years ending after September 25, 1980, in 
applying section 4211(c)(2)(B)(ii)(II) and section 4211(c)(2)(C)(i)(II) 
of ERISA.
    (2) A plan amendment made pursuant to paragraph (e)(1) of this 
section must provide that the plan's unfunded vested benefits for plan 
years ending after the designated plan year are reduced by the value of 
all outstanding claims for withdrawal liability that can reasonably be 
expected to be collected from employers that had withdrawn from the 
plan as of the end of the designated plan year.

19. Add Sec.  4211.14 to read as follows:


Sec.  4211.14  Simplified methods for disregarding certain 
contributions.

    (a) In general. A plan sponsor may amend a plan without PBGC 
approval to adopt any of the simplified methods in paragraphs (b) 
through (d) of this section to fulfill the requirements of section 
305(g)(3) of ERISA and section 432(g)(3) of the Code and Sec.  
4211.4(b)(2) in determining an allocation fraction. Examples 
illustrating calculations using the simplified methods in this section 
are provided in the appendix to this part.
    (b) Simplified method for the numerator--after 2014 plan year. A 
plan sponsor may amend a plan to provide that the withdrawing 
employer's required contributions for each plan year (a ``target 
year'') after the date that is the later of the last day of the first 
plan year that ends on or after December 31, 2014 and the last day of 
the plan year the employer first contributes to the plan (the 
``employer freeze date'') is the product of--
    (1) The employer's contribution rate in effect on the employer 
freeze date, plus any contribution increase in Sec.  4211.4(b)(2)(ii) 
that is effective after the employer freeze date but not later than the 
last day of the target year; times
    (2) The employer's contribution base units for the target year.
    (c) Simplified method for the denominator--after 2014 plan year. A 
plan sponsor may amend a plan to provide that the denominator for the 
allocation fraction for each plan year after the employer freeze date 
is calculated using the same principles as paragraph (b) of this 
section.
    (d) Simplified method for the denominator--proxy group averaging. 
(1) A plan sponsor may amend a plan to provide that, for purposes of 
determining the denominator of the unfunded vested benefits allocation 
fraction, employer contributions for a plan year beginning after the 
plan freeze date described in paragraph (d)(2)(i) of this section are 
calculated, in accordance with this paragraph (d), based on an average 
of representative contribution rates that exclude contribution 
increases that are required to be disregarded in determining withdrawal 
liability. The method described in this paragraph (d) is effective only 
for plan years to which the amendment applies.
    (2) For purposes of this paragraph (d) --
    (i) Plan freeze date means the last day of the first plan year that 
ends on or after December 31, 2014.
    (ii) Base year means the first plan year beginning after the plan 
freeze date.
    (iii) Contribution history for a plan year means the history of 
total contribution rates, and contribution rates that are not required 
to be disregarded in determining withdrawal liability, from the plan 
freeze date up to the end of the plan year.
    (iv) Included employer with respect to a plan for a plan year means 
an employer that is a contributing employer of the plan on at least 1 
day of the plan year and whose contributions for the plan year are to 
be taken into account under the plan in determining the denominator of 
the unfunded vested benefits allocation fraction under section 4211 of 
ERISA. If the contribution histories of different categories of 
employees of an employer are not substantially the same, the employer 
may be treated as two or more employers that have more uniform 
contribution histories.
    (v) Rate history group is defined in paragraph (d)(3) of this 
section.
    (vi) Proxy group is defined in paragraph (d)(4) of this section.
    (vii) Adjusted as applied to contributions for an employer, a rate 
history group, or a plan is defined in paragraphs (d)(5), (6), and (7) 
of this section.
    (3) A rate history group of a plan for a plan year is a group of 
included employers satisfying all of the following requirements:
    (i) Each included employer of the plan is in one and only one rate 
history group.
    (ii) The employers in the rate history group have substantially the 
same contribution history (or the same percentage increases in 
contributions from year to year), but there need not be more than ten 
rate history groups.
    (iii) There is consistency in the composition of rate history 
groups from year to year.
    (4) The proxy group of a plan for a plan year is a group of 
included employers satisfying all of the following requirements:
    (i) On at least 1 day of the plan year, the employers in the proxy 
group represent at least 10 percent of active plan participants.
    (ii) There is at least one employer in the proxy group from each 
rate history group of the plan for the plan year that represents, on at 
least 1 day of the plan year, at least 5 percent of active plan 
participants.
    (iii) There is consistency in the composition of the proxy group 
from year to year.
    (5) The adjusted contributions of an employer under a plan for a 
plan year are --
    (i) The employer's contribution base units for the plan year; 
multiplied by
    (ii) The employer's contribution rate per contribution base unit at 
the end of the plan year, reduced by the sum of the employer's 
contribution rate increases since the plan freeze date that are 
required to be disregarded in determining withdrawal liability.
    (6) The adjusted contributions of a rate history group that is 
represented in the proxy group of a plan for a plan year are the total 
contributions for the plan year attributable to employers in the rate 
history group, multiplied by the adjustment factor for the rate history 
group. The adjustment factor for the rate history group is the 
quotient, for all employers in the rate history group that are also in 
the proxy group, of --
    (i) Total adjusted contributions for the plan year; divided by
    (ii) Total contributions for the plan year.
    (7) The adjusted contributions of a plan for a plan year are the 
plan's total contributions for the plan year by all employers, 
multiplied by the adjustment factor for the plan. For this purpose, 
``the plan's total contributions for the plan year'' means the total 
unadjusted plan contributions for the plan year that would otherwise be 
included in the denominator of the allocation fraction in the absence 
of section 305(g)(1) of ERISA, including any employer contributions 
owed with respect to earlier periods that were collected in that plan 
year, and excluding any amounts contributed in that plan year by an 
employer that withdrew from the plan during that plan year. The 
adjustment factor for the plan is the quotient, for all rate history 
groups that are represented in the proxy group, of --
    (i) Total adjusted contributions for the plan year; divided by
    (ii) Total contributions for the plan year.
    (8) Under this method, in determining the denominator of a plan's 
unfunded vested benefits allocation fraction, the contributions taken 
into account with respect to any plan year (beginning with the base 
year) are the plan's adjusted contributions for the plan year.
    (9) Notwithstanding the foregoing provisions of this paragraph (d), 
if total contributions for a year for a rate history group or for a 
plan are not timely and reasonably available for calculating adjusted 
contributions for that year,

[[Page 1274]]

each relevant contribution rate for the year may be multiplied by the 
projected contribution base units for the year corresponding to that 
rate and the sum, for all rates, may be used in place of total 
contributions for that year.
    (e) Effective and applicability dates. (1) Effective date. This 
section is effective on February 8, 2021.
    (2) Applicability date. This section applies to employer 
withdrawals from multiemployer plans that occur in plan years beginning 
on or after February 8, 2021.

20. Add Sec.  4211.15 to read as follows:


Sec.  4211.15  Simplified methods for determining expiration date of a 
collective bargaining agreement.

    (a) In general. A plan sponsor may amend a plan without PBGC 
approval to adopt any of the simplified methods in this section to 
fulfill the requirements of section 305(g)(4) of ERISA and 432(g)(4) of 
the Code and Sec.  4211.4(b)(2)(iii) for a withdrawal that occurs on or 
after the plan's reversion date.
    (b) Reversion date. The reversion date is either--
    (1) The expiration date of the first collective bargaining 
agreement requiring plan contributions that expires after the plan is 
no longer in endangered or critical status, or
    (2) The date that is the later of--
    (i) The end of the first plan year following the plan year in which 
the plan is no longer in endangered or critical status; or
    (ii) The end of the plan year that includes the expiration date of 
the first collective bargaining agreement requiring plan contributions 
that expires after the plan is no longer in endangered or critical 
status.
    (3) For purposes of paragraph (b)(2) of this section, the 
expiration date of a collective bargaining agreement that by its terms 
remains in force until terminated by the parties thereto is considered 
to be the earlier of--
    (i) The termination date agreed to by the parties thereto; or
    (ii) The first day of the third plan year following the plan year 
in which the plan is no longer in endangered or critical status.
    (c) Example. The simplified method in paragraph (b)(1) of this 
section is illustrated by the following example.
    (1) Facts. A plan certifies that it is not in endangered or 
critical status for the plan year beginning January 1, 2021. The plan 
operates under several collective bargaining agreements. The plan 
sponsor adopts a rule providing that all contribution increases will be 
included in the numerator and denominator of the allocation fractions 
for withdrawals occurring after October 31, 2022, the expiration date 
of the first collective bargaining agreement requiring plan 
contributions that expires after January 1, 2021.
    (2) Allocation fraction. A contributing employer withdraws from the 
plan in November 2022, after the date designated by the plan sponsor 
for the inclusion of all contribution rate increases in the allocation 
fraction. The allocation fraction used by the plan sponsor to determine 
the employer's share of the plan's unfunded vested benefits includes 
all of the employer's required contributions in the numerator and total 
contributions made by all employers in the denominator, including any 
amounts related to contribution increases previously disregarded.
    (d) Effective and applicability dates. (1) Effective date. This 
section is effective on February 8, 2021.
    (2) Applicability date. This section applies to employer 
withdrawals from multiemployer plans that occur in plan years beginning 
on or after February 8, 2021.

21. Add Sec.  4211.16 to read as follows:


Sec.  4211.16  Simplified methods for disregarding benefit reductions 
and benefit suspensions.

    (a) In general. A plan sponsor may amend a plan without PBGC 
approval to adopt the simplified methods in this section to fulfill the 
requirements of section 305(g)(1) of ERISA and section 432(g)(1) of the 
Code and Sec.  4211.6 to disregard benefit reductions and benefit 
suspensions.
    (b) Basic rule. The withdrawal liability of a withdrawing employer 
is the sum of paragraphs (b)(1) and (2) of this section, and then 
adjusted by paragraphs (A)-(D) of section 4201(b)(1) of ERISA. The 
amount determined under paragraph (b)(1) may not be less than zero.
    (1) The amount that would be the employer's allocable amount of 
unfunded vested benefits determined in accordance with section 4211 of 
ERISA under the method in use by the plan without regard to Sec.  
4211.6 (but taking into account Sec.  4211.4); and
    (2) The employer's proportional share of the value of each of the 
benefit reductions and benefit suspensions required to be disregarded 
under Sec.  4211.6 determined in accordance with this section.
    (c) Benefit suspension. This paragraph (c) applies to a benefit 
suspension under Sec.  4211.6(a)(3).
    (1) General. The employer's proportional share of the present value 
of a benefit suspension as of the end of the plan year before the 
employer's withdrawal is determined by applying paragraph (c)(2) or (3) 
of this section to the present value of the suspended benefits, as 
authorized by the Department of the Treasury in accordance with section 
305(e)(9) of ERISA, calculated either as of the date of the benefit 
suspension or as of the end of the plan year coincident with or 
following the date of the benefit suspension (the ``authorized 
value'').
    (2) Static value method. A plan may provide that the present value 
of the suspended benefits as of the end of the plan year in which the 
benefit suspension takes effect and for each of the succeeding 9 plan 
years is the authorized value in paragraph (c)(1) of this section. An 
employer's proportional share of the present value of a benefit 
suspension to which this paragraph (c) applies using the static value 
method is determined by multiplying the present value of the suspended 
benefits by a fraction--
    (i) The numerator is the sum of all contributions required to be 
made by the withdrawing employer for the 5 consecutive plan years 
ending before the plan year in which the benefit suspension takes 
effect; and
    (ii) The denominator is the total of all employers' contributions 
for the 5 consecutive plan years ending before the plan year in which 
the suspension takes effect, increased by any employer contributions 
owed with respect to earlier periods which were collected in those plan 
years, and decreased by any amount contributed by an employer that 
withdrew from the plan during those plan years. If a plan uses an 
allocation method other than the presumptive method in section 4211(b) 
of ERISA or similar method, the denominator after the first year is 
decreased by the contributions of any employers that withdrew from the 
plan and were unable to satisfy their withdrawal liability claims in 
any year before the employer's withdrawal.
    (iii) In determining the numerator and the denominator in paragraph 
(c)(2) of this section, the rules under Sec.  4211.4 (and permissible 
modifications under Sec.  4211.12 and simplified methods under 
Sec. Sec.  4211.14 and 4211.15) apply.
    (3) Adjusted value method. A plan may provide that the present 
value of the suspended benefits as of the end of the plan year in which 
the benefit suspension takes effect is the authorized value in 
paragraph (c)(1) of this section and that the present value as of the 
end of each of the succeeding nine plan years (the ``revaluation 
date'') is the present value, as of a revaluation date, of the benefits 
not expected to be paid

[[Page 1275]]

after the revaluation date due to the benefit suspension. An employer's 
proportional share of the present value of a benefit suspension to 
which this paragraph (c) applies using the adjusted value method is 
determined by multiplying the present value of the suspended benefits 
by a fraction--
    (i) The numerator is the sum of all contributions required to be 
made by the withdrawing employer for the 5 consecutive plan years 
ending before the employer's withdrawal; and
    (ii) The denominator is the total of all employers' contributions 
for the 5 consecutive plan years ending before the employer's 
withdrawal, increased by any employer contributions owed with respect 
to earlier periods which were collected in those plan years, and 
decreased by any amount contributed by an employer that withdrew from 
the plan during those plan years.
    (iii) In determining the numerator and the denominator in this 
paragraph (c)(3), the rules under Sec.  4211.4 (and permissible 
modifications under Sec.  4211.12 and simplified methods under 
Sec. Sec.  4211.14 and 4211.15) apply.
    (iv) If a benefit suspension in Sec.  4211.6(a)(3) is a temporary 
suspension of the plan's payment obligations as authorized by the 
Department of the Treasury, the present value of the suspended benefits 
in this paragraph (c)(3) includes only the value of the suspended 
benefits through the ending period of the benefit suspension.
    (d) Benefit reductions. This paragraph (d) applies to benefits 
reduced under Sec.  4211.6(a)(1) or (2).
    (1) Value of a benefit reduction. The value of a benefit reduction 
is--
    (i) The unamortized balance, as of the end of the plan year before 
the withdrawal, of;
    (ii) The value of the benefit reduction as of the end of the plan 
year in which the reduction took effect; and
    (iii) Determined using the same assumptions as for unfunded vested 
benefits and amortization in level annual installments over a period of 
15 years.
    (2) Employer's proportional share of a benefit reduction. An 
employer's proportional share of the value of a benefit reduction to 
which this paragraph (d) applies is determined by multiplying the value 
of the benefit reduction by a fraction--
    (i) The numerator is the sum of all contributions required to be 
made by the withdrawing employer for the 5 consecutive plan years 
ending before the employer's withdrawal; and
    (ii) The denominator is the total of all employers' contributions 
for the 5 consecutive plan years ending before the employer's 
withdrawal, increased by any employer contributions owed with respect 
to earlier periods which were collected in those plan years, and 
decreased by any amount contributed by an employer that withdrew from 
the plan during those plan years.
    (iii) The 5 consecutive plan years ending before the plan year in 
which the adjustable benefit reduction takes effect may be used in 
determining the numerator and the denominator in this paragraph (d). If 
such 5-year period is used, in determining the denominator, if a plan 
uses an allocation method other than the presumptive method in section 
4211(b) of ERISA or similar method, the denominator after the first 
year is decreased by the contributions of any employers that withdrew 
from the plan and were unable to satisfy their withdrawal liability 
claims in any year before the employer's withdrawal.
    (iv) In determining the numerator and the denominator in this 
paragraph (d), the rules under Sec.  4211.4 (and permissible 
modifications under Sec.  4211.12 and simplified methods under 
Sec. Sec.  4211.14 and 4211.15) apply.
    (e) Example. The simplified framework using the static value method 
under Sec.  4211.16(c)(2) for disregarding a benefit suspension is 
illustrated by the following example.
    (1) Facts. Assume that a calendar year multiemployer plan receives 
final authorization by the Secretary of the Treasury for a benefit 
suspension, effective January 1, 2018. The present value, as of that 
date, of the benefit suspension is $30 million. Employer A, a 
contributing employer, withdraws during the 2022 plan year. Employer 
A's proportional share of contributions for the 5 plan years ending in 
2017 (the year before the benefit suspension takes effect) is 10 
percent. Employer A's proportional share of contributions for the 5 
plan years ending before Employer A's withdrawal in 2022 is 11 percent. 
The plan uses the rolling-5 method for allocating unfunded vested 
benefits to withdrawn employers under section 4211 of ERISA. The plan 
sponsor has adopted by amendment the static value simplified method for 
disregarding benefit suspensions in determining unfunded vested 
benefits. Accordingly, there is a one-time valuation of the initial 
value of the suspended benefits with respect to employer withdrawals 
occurring during the 2019 through 2028 plan years, the first 10 years 
of the benefit suspension.
    (2) Unfunded vested benefits allocable to Employer A. To determine 
the amount of unfunded vested benefits allocable to Employer A, the 
plan's actuary first determines the amount of Employer A's withdrawal 
liability as of the end of 2021 assuming the benefit suspensions remain 
in effect. Under the rolling-5 method, if the plan's unfunded vested 
benefits as determined in the plan's 2021 plan year valuation were $170 
million (not including the present value of the suspended benefits), 
the share of these unfunded vested benefits allocable to Employer A is 
equal to $170 million multiplied by Employer A's allocation fraction of 
11 percent, or $18.7 million. The plan's actuary then adds to this 
amount Employer A's proportional 10 percent share of the $30 million 
initial value of the suspended benefits, or $3 million. Employer A's 
share of the plan's unfunded vested benefits for withdrawal liability 
purposes is $21.7 million ($18.7 million + $3 million).
    (3) Adjustment of allocation fraction. If another significant 
contributing employer--Employer B--had withdrawn in 2019 and was unable 
to satisfy its withdrawal liability claim, the allocation fraction 
applicable to the value of the suspended benefits is adjusted. The 
contributions in the denominator for the last 5 plan years ending in 
2017 is reduced by the contributions that were made by Employer B, 
thereby increasing Employer A's allocable share of the $30 million 
value of the suspended benefits.
    (f) Effective and applicability dates. (1) Effective date. This 
section is effective on February 8, 2021.
    (2) Applicability date. This section applies to employer 
withdrawals from multiemployer plans that occur in plan years beginning 
on or after February 8, 2021.

APPENDIX TO PART 4211--EXAMPLES

    The examples in this appendix illustrate simplified methods for 
disregarding certain contribution increases in the allocation 
fraction provided in Sec.  4211.14 of this part.
    Example 1. Determining the Numerator of the Allocation Fraction 
Using the Employer's Plan Year 2014 Contribution Rate (Sec.  
4211.14(b)).
    Assume Plan X is a calendar year multiemployer plan in critical 
status which did not have a benefit increase after plan year 2014. 
In accordance with section 305(g)(3)(B) of ERISA, the annual 5 
percent contribution rate increases applicable to Employer A and 
other employers in Plan X after the 2014 plan year were deemed to be 
required to enable the plan to meet the requirement of its 
rehabilitation plan and must be disregarded. Employer A, a 
contributing employer, withdraws from Plan X in 2021. Using the 
rolling-5 method, Plan X has unfunded vested benefits of $200 
million as of the end of the 2020 plan year. To determine Employer 
A's allocable share of these unfunded vested benefits, Employer A's 
hourly required contribution rate and contribution base units for 
the 2014 plan year and each of the 5 plan years between 2016 and 
2020 are identified as shown in the following table:

--------------------------------------------------------------------------------------------------------------------------------------------------------
                                                                                                                                                5-year
                                                                 2014 PY      2016 PY      2017 PY      2018 PY      2019 PY      2020 PY       total
--------------------------------------------------------------------------------------------------------------------------------------------------------
Employer A's Contribution Rate...............................        $5.51          n/a          n/a          n/a          n/a          n/a  ...........
Contribution Base Units......................................      800,000      800,000      800,000      900,000      900,000      900,000    4,300,000
Contributions................................................       $4.41M       $4.86M       $5.10M       $6.03M       $6.33M       $6.64M      $28.96M
--------------------------------------------------------------------------------------------------------------------------------------------------------

    The plan sponsor makes a determination pursuant to section 
305(g)(3) of ERISA that the annual 5 percent contribution rate 
increases applicable to Employer A and other employers in Plan X 
after the 2014 plan year were required to enable the plan to meet 
the requirement of its rehabilitation plan and should be 
disregarded; benefits were not increased after plan year 2014.
    Applying the simplified method, contribution rate increases that 
went into effect during plan years beginning after December 31, 2014 
would be disregarded: The $5.51 contribution rate in effect at the 
end of plan year 2014 would be held steady in computing Employer A's 
required contributions for the plan years included in the numerator 
of the allocation fraction. Based on 4.3 million contribution base 
units, this results in total required contributions of $23.7 million 
over 5 years. Absent section 305(g)(3) of ERISA, the sum of the 
contributions required to be made by Employer A would have been 
determined by multiplying Employer A's contribution rate in effect 
for each plan year by the contribution base units in that plan year, 
producing total required contributions of $28.96 million over 5 
years.
    Example 2. Determining the Denominator of the Allocation 
Fraction Using the Proxy Group Method (Sec.  4211.14(d)).
    Assume a plan covers ten employers. For 2017, three small 
employers were in rate history group X, representing less than 5 
percent of active plan participants; employers A and B and two other 
employers were in rate history group Y; and employer C and two other 
employers were in rate history group Z. For 2018, there were changes 
in contribution rates for some of B's employees, and as a result, 
employer B is being treated as two employers, B1 and B2. B1 remained 
in rate history group Y because, while B1 has a significantly lower 
contribution rate than A, the contributions of both are subject to 
the same percentage increase each year. B2 was added to rate history 
group X. X continues to represent less than 5 percent of active plan 
participants, and the plan continues to ignore it in forming the 
proxy group. The plan forms a 2018 proxy group of three employers--A 
and B1 from rate history group Y and C from rate history group Z--
that together represent more than 10 percent of active plan 
participants.
    Contributions for 2018 are $1,000,000: $20,000 for rate history 
group X, $740,000 for rate history group Y, and $240,000 for rate 
history group Z, with A and B1 accounting for $150,000 and C 
accounting for $45,000 of the total contribution amounts.
    Contribution rates for 2018 for A, B1, and C (excluding rate 
increases required to be disregarded for withdrawal liability 
purposes) and contribution base units for the three employers are: 
For A, 87 cents and 100,000 CBUs; for B1, 43 cents and 50,000 CBUs; 
and for C, 70 cents and 60,000 CBUs, as shown in rows (1) and (2) of 
the table below. Thus, the three employers' adjusted contributions 
are $87,000, $21,500, and $42,000 respectively, as shown in row (3).
    Moving from the employer level to the rate history group level, 
the adjusted contributions for employers in the proxy group that are 
in the same rate history group are added together (row (4)). Those 
totals are then divided by total actual contributions for the proxy 
group employers in each rate history group (row (6)) to derive an 
adjustment factor for each rate history group (row (7)) that is 
applied to the actual contributions of all employers in the rate 
history group (row (8)) to get the adjusted contributions for each 
rate history group represented in the proxy group (row (9)).
    Moving from the rate history group level to the plan level, the 
same process is repeated. Adjusted employer contributions for the 
rate history group are summed (row (10)) and divided by the total 
contributions for all rate history groups represented in the proxy 
group (row (11)) to get an adjustment factor for the plan (row 
(12)). Contributions for rate history group X are excluded from row 
(11) because no employer in rate history group X is in the proxy 
group. The adjustment factor for the plan is then applied to total 
plan contributions (row (13)) to get adjusted plan contributions 
(row (14)). Contributions for rate history group X are included in 
row (13) because--although X was ignored in determining the 
adjustment factor for the plan -- the adjustment factor applies to 
all plan contributions (other than those by employers excluded from 
the plan's allocation fraction denominator). The plan will use the 
adjusted plan contributions in row (14) as the total contributions 
for 2018 in determining the denominator of any allocation fraction 
that includes contributions for 2018.

31. Add Sec.  4219.3 to read as follows:


Sec.  4219.3  Disregarding certain contributions.

    (a) General rule. For purposes of determining the highest 
contribution rate under section 4219(c) of ERISA, a plan must 
disregard:
    (1) Surcharge. Any surcharge under section 305(e)(7) of ERISA and 
section 432(e)(7) of the Code the obligation for which accrues on or 
after December 31, 2014.
    (2) Contribution increase. Any increase in the contribution rate or 
other increase in contribution requirements

that goes into effect during a plan year beginning after December 31, 
2014, so that a plan may meet the requirements of a funding improvement 
plan under section 305(c) of ERISA and section 432(c) of the Code or a 
rehabilitation plan under section 305(e) of ERISA and section 432(e) of 
the Code, except to the extent that one of the following exceptions 
applies pursuant to section 305(g)(3) of ERISA and section 432(g)(3) of 
the Code:
    (i) The increases in contribution requirements are due to increased 
levels of work, employment, or periods for which compensation is 
provided.
    (ii) The additional contributions are used to provide an increase 
in benefits, including an increase in future benefit accruals, 
permitted by section 305(d)(1)(B) or (f)(1)(B) of ERISA and section 
432(d)(1)(B) or (f)(1)(B) of the Code.
    (b) Simplified method for a plan that is no longer in endangered or 
critical status. A plan sponsor may amend a plan without PBGC approval 
to use the simplified method in this paragraph (b) for purposes of 
determining the highest contribution rate for a plan that is no longer 
in endangered or critical status. The highest contribution rate is the 
greater of--
    (1) The employer's contribution rate as of the date that is the 
later of the last day of the first plan year that ends on or after 
December 31, 2014 and the last day of the plan year the employer first 
contributes to the plan (the ``employer freeze date'') plus any 
contribution increases after the employer freeze date, and before the 
employer's withdrawal date that are determined in accordance with the 
rules under Sec.  4219.3(a)(2)(ii); or
    (2) The highest contribution rate for any plan year after the plan 
year that includes the expiration date of the first collective 
bargaining agreement of the withdrawing employer requiring plan 
contributions that expires after the plan is no longer in endangered or 
critical status, or, if earlier, the date as of which the withdrawing 
employer renegotiated a contribution rate effective after the plan year 
the plan is no longer in endangered or critical status.
    (c) Example: The simplified method in paragraph (b) of this section 
is illustrated by the following example.
    (1) Facts. A contributing employer withdraws in plan year 2028, 
after the 2027 expiration date of the first collective bargaining 
agreement requiring plan contributions that expires after the plan is 
no longer in critical status in plan year 2026. The plan sponsor 
determines that under the expiring collective bargaining agreement the 
employer's $4.50 hourly contribution rate in plan year 2014 was 
required to increase each year to $7.00 per hour in plan year 2025, to 
enable the plan to meet its rehabilitation plan. The plan sponsor 
determines that, over this period, a cumulative increase of $0.85 per 
hour was used to fund benefit increases, as provided by plan amendment. 
Under a new collective bargaining agreement effective in 2027, the 
employer's hourly contribution rate is reduced to $5.00.
    (2) Highest contribution rate. The plan sponsor determines that the 
employer's highest contribution rate for purposes of section 4219(c) of 
ERISA is $5.35, because it is the greater of the highest rate in effect 
after the plan is no longer in critical status ($5.00) and the 
employer's contribution rate in plan year 2014 ($4.50) plus any 
increases between 2015 and 2025 ($0.85) that were required to be taken 
into account under section 305(g)(3) of ERISA.
    (d) Effective and applicability dates. (1) Effective date. This 
section is effective on February 8, 2021.
    (2) Applicability date. This section applies to employer 
withdrawals from multiemployer plans that occur in plan years beginning 
on or after February 8, 2021.
