On September 9, 2016, Representative John Kline, chairman of the House Committee on Education and the Workforce in the 114^th Congress, issued a discussion draft that would authorize a new multiemployer pension plan called a composite plan.¹ The discussion draft was introduced, with some modifications, as H.R. 4997, the Giving Retirement Options to Workers Act of 2018 (the GROW Act), by Representatives Phil Roe and Donald Norcross in the 115^th Congress. In the 116^th Congress, the GROW Act was included in H.R. 6379, the Take Responsibility for Workers and Families Act, and H.R. 6800, the HEROES Act.

A composite plan would contain features of two types of existing pension plans: (1) defined benefit (DB) plans, in which participants receive regular monthly benefit payments in retirement (which some refer to as a "traditional" pension), and (2) defined contribution (DC) plans (of which the 401(k) plan is the most common), in which participants have individual accounts that can provide a source of income in retirement.² Since composite plans would be neither DB nor DC plans, authorizing legislation is necessary to implement the proposal.

This report provides background on multiemployer pension plans; summarizes the GROW Act, which would authorize composite plans, and explains the main features of these proposed plans; and explores various policy discussions surrounding composite plans, including their potential benefits and drawbacks for employers and employees, their possible implications for the Pension Benefit Guaranty Corporation (PBGC), and their potential effects on the broader retirement system.

Background on Multiemployer Pensions

In addition to being classified as DB or DC plans, pension plans are also classified by whether they are sponsored by one employer (single-employer plans) or by more than one employer (multiemployer and multiple employer plans). Multiemployer pension plans are sponsored by employers in the same industry and maintained as part of a collective bargaining agreement.³

In 2018, there were 1,373 multiemployer DB pension plans that covered 10.6 million participants.⁴ In 2016 (the most recent year for which funding information is available), 1,375 multiemployer plans had $467.0 billion in assets and $1,105.5 billion in liabilities (future benefit obligations) for a total amount of underfunding of $638.5 billion.⁵

Underfunded multiemployer plans that meet specified financial criteria are required to report to the Internal Revenue Service (IRS) their financial condition as being in one of several categories. The categories are (1) endangered (or a subcategory called seriously endangered) (both are sometimes called "yellow zone"),⁶ (2) critical (sometimes called "red zone"),⁷ and (3) critical and declining.⁸ Plans that do not meet the criteria for any of these categories are sometimes referred to as being in the "green zone." Analysis of 2017 pension plan disclosures indicated that of 1,229 plans that reported their zone status, 132 plans were in endangered or seriously endangered status, 190 plans were in critical status, 113 plans were in critical and declining status, and 794 were in green zone status.⁹

To address the concerns about likely insolvency of a number of multiemployer plans, Congress approved changes to multiemployer DB pension funding rules in the Multiemployer Pension Reform Act of 2014 (MPRA, enacted as Division O in the Consolidated and Further Continuing Appropriations Act, 2015; P.L. 113-235).¹⁰ Among other provisions, plans in critical and declining status may be eligible to apply to the Department of the Treasury to reduce benefits. MPRA did not address new pension plan structures, such as composite plans.¹¹ Some Members of Congress indicated that the proposal for composite plans is a continuation of the work done in MPRA.¹²

Pension Benefit Guaranty Corporation Insurance

The PBGC was established by the Employee Retirement Income Security Act of 1974 (ERISA; P.L. 93-406) to insure benefits in private-sector DB pension plans.¹³ It operates two insurance programs: one for single-employer pension plans and a second for multiemployer pension plans. The two programs operate independently of each other.

When a multiemployer DB pension plan becomes insolvent, PBGC provides financial assistance to the plan to pay participants' benefits. When a multiemployer plan receives financial assistance from PBGC, the plan must reduce participants' benefits to a maximum per participant benefit as set in statute.¹⁴ The maximum benefit is calculated as: 100% of the first $11 of the monthly benefit rate, plus 75% of the next $33 of the monthly benefit rate, times the participant's years of credited service. For example, an individual with 30 years of service in the plan could receive a maximum benefit of [30 × (100% × $11 + 75% × $33)] = $12,870 per year.¹⁵ The benefit is lower for individuals with fewer than 30 years of service in the plan.

PBGC's multiemployer program receives funds from premiums paid by participating employers ($310 million in FY2019) and from the interest earnings off the investment of unused premium income ($442 million in FY2019).¹⁶ The poor financial condition of some multiemployer DB pension plans threatens the solvency of PBGC's multiemployer insurance program. There are no provisions in law that provide for assistance from the U.S. Treasury in the event of PBGC's insolvency. ERISA states that "the United States is not liable for any obligation or liability incurred by the corporation."¹⁷

At the end of FY2019, PBGC reported a deficit of $65.2 billion in the multiemployer insurance program.¹⁸ If a sufficient number of multiemployer pension plans exhaust their plan assets and become unable to pay promised benefits, it is likely that PBGC would also exhaust its assets. PBGC indicated that insolvency is likely by the end of 2025 and a near certainty by 2026.¹⁹

The Congressional Budget Office (CBO) provided several estimates of PBGC's financial condition.²⁰ CBO's cash-based estimates account for spending and revenue in the years when they are expected to occur. CBO estimates that from 2017 to 2026, PBGC will be obligated to pay $9 billion in claims but will only have sufficient resources to pay $6 billion. From 2027 to 2036, claims to PBGC will be $35 billion but PBGC will only have sufficient resources to pay $5 billion. CBO also provided fair-value estimates, which are the present value of all expected future claims for financial assistance, net of premiums received.²¹ CBO's fair-value estimate of PBGC's future obligations was $101 billion.

Defined Benefit, Defined Contribution, and Proposed Composite Plans: Comparison of Main Features

Table 1 compares the main features of DB, DC, and proposed composite plans.

Overview of the GROW Act

As a result of the financial challenges facing multiemployer DB pension plans, stakeholders have sought alternative pension plan designs, such as composite plans, that could alleviate some of the concerns but retain some of the beneficial features. These alternative plan designs would need to be authorized in ERISA.²²

The proposal for composite plans for plan sponsors was included in Solutions Not Bailouts, a 2013 report by a coalition of labor and management groups organized by the National Coordinating Committee for Multiemployer Plans (NCCMP), an organization of multiemployer pension and health plans.²³ Advocates for composite plans note that plans similar to composite plans are found in other countries.²⁴ For example, the Canadian government and several provinces in Canada have been considering or implementing the regulatory changes needed for employers to more widely adopt alternative plan structures, which are referred to as target benefit plans in Canada.²⁵

Main Features of the Proposed Composite Plan

A composite plan, as would be authorized in the GROW Act, would be neither a DB nor a DC pension plan, though it would contain elements of both. As discussed in greater detail in the following sections, the main features of the proposed composite plan would be the following:

• A participant's benefit amount would be based on a formula and payable as a life annuity.²⁶
• Employer contributions²⁷ would remain at a fixed amount (as negotiated between labor and management) and would not be required to increase in response to underfunding.²⁸
• Composite plans would be required to maintain a projected funding ratio of 120%.²⁹ If the amount of the plan's assets were insufficient to pay 120% of the promised benefits, the plan would be required to take corrective action to restore the funding ratio to 120%.
• The options for corrective actions (called a realignment program in the GROW Act) include possible employer contribution increases (if agreed to by the bargaining parties) and reductions to participants' benefits (which do not require agreement by the bargaining parties).³⁰
• Composite plans would not be covered by PBGC. Therefore, plan sponsors would not pay PBGC premiums and participants' benefits would not be protected if the plan were to become insolvent.
• Composite plans would not feature withdrawal liability. Withdrawal liability is a payment or series of payments by an employer that seeks to no longer participate in a multiemployer DB pension plan. The calculation of withdrawal liability is based on the employer's share of unfunded benefits that are owed to participants in the plan.

An existing multiemployer DB pension plan (except for a plan that was in critical status) could adopt a composite plan while maintaining an existing DB plan. The existing plan would be referred to as a legacy plan. The main features of a legacy plan would be

• participants in a legacy plan whose employers opted for the composite plan would cease to earn benefits in the legacy plan and begin to earn benefits in the composite plan;³¹ and
• employers would generally be required to contribute to the legacy plan at minimum funding levels (called a transition contribution rate). The minimum funding levels should, in principle, restore the legacy plan to a 100% funding level over time. The legacy plans would continue to be insured by PBGC.

Key Provisions in the GROW Act

This section summarizes in greater detail the main provisions in the GROW Act.³² The bill authorizes the creation of multiemployer composite plans and establishes the requirements that composite plans would have to meet. The bill also establishes rules for existing multiemployer DB plans to which composite plans would be added.

Legislation that affects private-sector pensions often amends both Title 29 (Labor Code) and Title 26 (Internal Revenue Code [IRC]) of the U.S. Code. The provisions in the GROW Act that amend the IRC are identical or nearly identical to the provisions that amend the Labor Code. Therefore, the IRC provisions are not included in this more detailed summary. For ease of comparison, the headings in this summary generally align with the headings in the GROW Act.

Requirements for a Composite Plan

A composite plan would be an employer-sponsored multiemployer pension plan that would be neither a DB plan (in which the benefit is fixed and cannot be reduced except under MPRA) nor a DC plan (in which participants have ownership of funds in an account).

A composite plan would systematically pay benefits that would be calculated according to a formula specified in the plan.³³ The benefit would be a monthly payment beginning at retirement and lasting for the life of the participant (and spouse, if married). The benefit could be reduced as part of a realignment program.

In the first year of the composite plan, the employer's contribution would be 120% of the plan's normal cost.³⁴

Each year, the plan would make two actuarial determinations of the plan's financial condition: (1) current funded ratio (CFR) and (2) projected funded ratio (PFR). These will be defined in the "Funded Ratios; Actuarial Assumptions" section of this report.

If the plan's PFR were less than 120%, the plan would be required to take corrective action, called a realignment program (described in detail later in this report).

The plan's trustees would include a retiree or beneficiary who would be receiving benefits from the plan.³⁵

A composite plan could be added as a component to an existing multiemployer plan or could be adopted as a stand-alone plan, provided the multiemployer DB plan is not in critical status nor is expected to be for the next five years.

If a composite plan were to be added to a multiemployer plan, the composite plan and multiemployer plan would be maintained as separate plans. The assets of each plan could be held in a single trust provided separate accounts were maintained. The plans could, but would not be required to, pool their assets.

The assets of each of the plans would be held, invested, reinvested, managed, administered, and distributed for the exclusive benefit of the participants and beneficiaries of each component. The assets of one component could not be used to pay for the benefits of the other component.

Funded Ratios; Actuarial Assumptions

Each year, a composite plan would report its CFR and PFR.

CFR would be calculated as the market value of plan assets divided by the present value of plan liabilities.

PFR would be the CFR projected 15 years into the future. The PFR could incorporate anticipated contribution increases of up to 2.5% per year beyond the term of the current collective bargaining agreement.

Costs, liabilities, and rates of interest would (1) use reasonable assumptions (taking into account the plan's experience and reasonable expectations) and (2) offer the best estimate of the plans anticipated experience.³⁶

Any changes to actuarial assumptions from the previous year would be documented by the plan actuary.

The value of plan assets would be at market values.³⁷

The value of plan liabilities would use the unit credit funding method.³⁸ The unit credit funding method is commonly used by multiemployer DB pension plans.³⁹

Realignment Program

If a composite plan's PFR were less than 120%, then the plan would have to adopt a realignment program, as described in the GROW Act. A realignment program would be a range of options that the plan sponsor or bargaining parties could undertake to achieve a PFR of 120% the following year.⁴⁰

The initial elements of a realignment program could, but are not required to, include

• proposed employer contribution increases;
• reductions in the rate of future benefit accruals;
• modification or elimination of adjustable benefits for participants not currently receiving benefits from the plan; and
• other lawfully available measures.⁴¹

If these measures would not enable the plan to achieve 120% PFR, then the plan could reduce

• accrued benefits for participants who are not yet receiving benefits from the plan; and
• non-core benefits to participants who are receiving benefits from the plan.⁴²

If the above measures were to fail to enable the plan to achieve 120% PFR, then the plan could

• further reduce future benefit accruals; and
• reduce core benefits to participants who are receiving benefits from the plan, provided the reductions are implemented equitably with respect to the factors listed in MPRA that allowed benefit reductions.⁴³

The realignment program could specify that the benefit reduction would take effect only if the bargaining parties failed to agree to contribution increases. There is no requirement that the realignment program include contribution increases.

There would be no limitation on benefit reductions.⁴⁴

Limitation on Increasing Benefits

The GROW Act contains provisions that would generally prohibit a composite plan from increasing benefits unless the plan was well funded.

A composite plan would not be able to increase benefits unless

• the plan's CFR was at least 110% before taking the benefit increases into account;
• the plan's CFR was at least 100% after taking the benefit increases into account;
• the plan's PFR was at least 120% after taking the benefit increases into account; and
• expected contributions for the current plan year (and assuming the benefit increases were in effect for the entire year) are at least 120% of normal cost for the year. If the plan's CFR and PFR were less than 140% after taking the benefit increases into account, the present value of plan liabilities could not increase by more than 3%.⁴⁵

If a plan had reduced core benefits as part of a realignment program, it could (1) only increase future benefit payments⁴⁶ and (2) provide for equitable distribution of benefit increases, taking into account the benefits that had been previously reduced.

Composite Plan Restrictions to Preserve Legacy Plan Funding

The GROW Act allows existing multiemployer DB plans to adopt composite plans provided the plan is not in critical status or expects to be in critical status in the next five years. The existing DB plan would become a legacy plan, which would still be required to pay participants' benefits that had been earned in the plan.

A legacy plan would be a multiemployer DB plan that had participants who (1) ceased to earn new benefits in the DB plan and (2) were eligible to earn benefits in a composite plan. A legacy plan would be covered by PBGC and pay PBGC premiums.

If an employer were to cease to have an obligation to a multiemployer DB plan (via a withdrawal from the DB plan), then that firm's employees would not be able to earn benefits in the related composite plan for five years after the withdrawal.

Composite plans would have to satisfy "transition contribution requirements" to ensure contributions would continue to the legacy plan.

The transition contribution rate would be the rate that would (1) fund the DB plan's normal cost for the plan year, (2) amortize the plan's initial unfunded liabilities over 25 years,⁴⁷ and (3) amortize subsequent unfunded liabilities over 15 years. The transition contribution rate in any given year could not be lower than the transition contribution rate in the first year.

If the status of the legacy plan were to become endangered or critical, then the transition contribution rate would be the greater of (1) the legacy contribution rate or (2) the rate determined under the funding improvement or rehabilitation plan (but not greater than 75% of the combined contribution rates to the legacy and composite plans).

The above restrictions on composite plans would cease to apply if the legacy plan (1) were fully funded in the current year, (2) had been fully funded in at least three of the previous five years, and (3) were projected to be fully funded in the following four years. The determination of fully funded would be in accordance with the determination of plan liabilities calculated as if all the employers had decided to leave the plan (referred to as a mass withdrawal).⁴⁸

Mergers and Asset Transfers of Composite Plans

Composite plans would be able to merge. The resulting plan would also have to be a composite plan. A participant's accrued benefit could not be lowered as a result of the merger. Employers would continue to make contributions to legacy plans if composite plans merge.

PBGC Coverage and Withdrawal Liability

Composite plans would not be covered by PBGC insurance, nor would plan sponsors pay PBGC premiums on the composite plan portion of their multiemployer plans.

Employers in composite plans would not be subject to any withdrawal liability.

In certain circumstances, employers in legacy plans would not have any withdrawal liability. A legacy plan would have no withdrawal liability if the plan (1) were fully funded for three of the previous five years, (2) had no unfunded vested benefits for at least three of the previous five years, and (3) were projected to be fully funded and to have no unfunded vested benefits for the next four years.⁴⁹

Concerns Raised by the GROW Act

If the GROW Act were to be enacted, the following are some possible concerns that some have raised.

Adjustable Benefit Plans Currently Exist

One of the main features of the composite plans proposal is that participants' benefits could be adjusted based on the performance of investments in the plan. This would relieve employers in the plan from the obligation to increase contributions in response to investment losses. This feature is already available to an extent in a type of DB plan called an adjustable benefit plan or variable defined benefit plan.⁵⁰ In this type of plan, participants are guaranteed (1) a minimum (also called a floor) benefit that is calculated using conservative assumptions⁵¹ plus (2) a variable benefit that can increase or decrease based on performance of the investments in the plan. A participant's benefit cannot be changed once payments begin in retirement.

The adjustable benefit plan differs from the composite plan proposal in several aspects: the plan would be responsible if there were insufficient assets from which to pay the floor benefits (as might occur if there were large investment losses); benefits would be insured by PBGC; the plan would continue to pay PBGC premiums; and employers would still be subject to withdrawal liability. Several plans have considered adopting adjustable benefit plans.⁵²

Potential Consequences for Legacy and Composite Plan Funding

Funding for existing multiemployer plans that adopt a composite plan as a component would be lower under the provisions of the GROW Act. This is because a plan could amortize existing underfunding over 25 years (an increase from 15 years under current law). All else being equal, each year's contribution to a legacy plan would be lower than under current law.

For composite plans that are adopted as a component of an existing multiemployer plan, contributions would be allocated to the legacy plan based on the legacy plan's transition contribution rate. In addition, if a legacy plan were to enter critical or endangered status, required contributions to the legacy plan would likely increase. If this were to occur, the composite plan could not receive less than 25% of the combined contribution to the legacy and the composite plan. This requirement could lead to a worsening of the legacy plan's funded status if required contributions in the legacy plan were more than 75% of the combined contributions to the legacy and composite plan.

Withdrawal Liability in Legacy Plans

Under the composite plan proposal, the amount that employers would have to pay in withdrawal liability to the legacy plan would likely decrease and could be permanently eliminated from a plan.

Under the composite plan proposal, an employer's withdrawal liability payments to a legacy DB plan would likely decrease, even though there might not be any change in the total amount of an employer's withdrawal liability. One of the components in the calculation of withdrawal liability payments is the average of contributions in the 10 years prior to an employer's withdrawal.⁵³ In a multiemployer DB plan in which participants are earning benefits, employers' contributions go toward (1) new benefits earned by participants and (2) an amortized portion of unfunded benefits. However, employer contributions to a legacy plan would only go toward an amortized portion of unfunded benefits, which would be lower as a result of the 25-year amortization of unfunded liabilities. The GROW Act would exclude contributions to a composite plan from the calculations of withdrawal liability payments.

Investment Policy in Composite Plans

A pension plan's investment policy determines the percentage of the plan's assets that are invested among several investment options, such as equities (stocks and bonds), fixed income (bonds), real estate, and alternative assets (such as private equity). The investment policy is made by the trustees of the plan or an investment policy committee and is a fiduciary duty, which means that decisions must be in the interest of plan participants.⁵⁴

In traditional DB plans, the employers who make the contributions to the plan bear the investment risk because their contributions would increase to make up for investment losses. In composite plans, participants would bear most of the investment risk because their benefits could decrease in response to investment losses.⁵⁵ It is possible that the asset allocation appropriate for a composite plan could differ from the asset allocation for a DB plan.⁵⁶ Because participants' benefits are generally at greater risk in composite plans, the appropriate investment allocation for a composite plan might be more conservative compared with DB plans.⁵⁷ The GROW Act does not contain provisions regarding investment allocations in composite plans.

Realignment Program Concerns

Some have suggested that the realignment program that would be adopted if funding levels in a composite plan were to fall to below 120% of plan liabilities could be made clearer.⁵⁸ For example, the GROW Act (1) indicates that a realignment program may include certain measures to be undertaken (such as proposed employer contribution increases or a reduction in benefit accruals) and (2) contains three "tiers" of measures as part of the realignment program. However, the GROW Act indicates that the measures in a given tier may—but does not require that they—be included in a realignment program. This potentially leaves plan trustees discretion about the adoption of the specific measures of a realignment program and participants uncertain about how their benefits would be affected by funding shortfalls.

Additionally, the PFR, which is the funding ratio used to determine whether a realignment program needs to be implemented, can include assumed contribution rate increases of up to 2.5% per year. Although contribution rate increases can assumed for the PFR, there is no requirement that they be implemented.

Proposal Does Not Address Existing Multiemployer Plans Facing Insolvency

The GROW Act does not contain any provisions to assist multiemployer plans in critical or critical and declining status, and plans in critical status are not permitted to adopt composite plans.⁵⁹ The GROW Act is not intended to address existing multiemployer plans financial difficulties—as noted earlier, it is meant to be one part of several proposals to address multiemployer plan issues. PBGC has indicated that the multiemployer insurance program is likely to become insolvent by 2025, as a result of several very large multiemployer plans in critical and declining status becoming insolvent.⁶⁰

Possible Adoption of Composite Plans

Existing multiemployer plans would not be required to adopt composite plans. However, some of the features of composite plans (such as fixed contributions, the absence of withdrawal liability, and no PBGC premiums) could be attractive, from an employer's point of view, and some employers in multiemployer DB plans may desire that their plan sponsors adopt composite plans.

In addition, the composite plan proposal is limited to the sponsors of multiemployer pension plans. It is also possible that the sponsors of existing single-employer DB pension plans could seek approval to adopt the composite plan model.⁶¹ However, employers that sponsor single-employer DB pension plans face few obstacles to freezing or terminating their DB pension plan and adopting DC plans.

Stakeholder Considerations

Stakeholders such as policymakers, Members of Congress, employers and unions that participate in multiemployer plans, and groups representing retirees have identified a number of benefits and drawbacks in the proposal for composite plans. Among other issues, these include benefits for employers, risks for participants, possible effects on PBGC, and funding for legacy and composite plans. The policy considerations for some of these stakeholders are summarized in Table 2.

Considerations for Employers

Employer concerns with existing multiemployer plans include (1) uncertainty over future contribution increases and (2) withdrawal liability. These concerns may cause employers in multiemployer DB plans to consider leaving their DB plans and establishing DC plans. In addition, these concerns make it difficult for existing multiemployer DB plans to attract new employers to the plan.⁶² The composite plan proposal addresses these concerns.

Certainty of Contributions

An employer's future contributions to a DB pension plan may unexpectedly increase as a result of investment losses or other decreases in a pension plan's funding ratio.⁶³ The composite plan proposal does not include mandatory employer contribution increases in the event of decreases to a plan's funding ratio. Employer contributions could remain fixed, which could be an attractive feature to prospective employers that might consider joining the plan. Investment losses and other changes that negatively affect a plan's funding ratio would be addressed by the realignment program which includes proposed but not mandatory contribution increases and mandatory benefit decreases.

Absence of Withdrawal Liability

Concerns about withdrawal liability might be a factor that deters employers from joining an existing multiemployer DB plan. When a plan has insufficient assets from which to pay 100% of promised benefits, employers that leave the plan are assessed an amount equal to their share of unfunded benefits. Withdrawal liability raises several concerns among employers: (1) the amount of the withdrawal liability can sometimes be very large, which might place a burden on the employers in the plan; and (2) the disclosure of withdrawal liability might prompt concerns among lenders and other creditors to a company, even for companies that have no intention of withdrawing from a plan.⁶⁴

Employers would likely find the absence of withdrawal liability an attractive feature of composite plans.

Pension Benefit Guaranty Corporation Premiums

Plan sponsors that adopt composite plans would not pay per participant annual premiums to PBGC.

Considerations for Participants

In a composite plan, participants would (1) receive their benefit for the remainder of their lives (or spouses' lifetime, if married) and would not be subject to the longevity risk associated with DC plans, (2) be exposed to investment risk if the value of plan assets decreases, and (3) be exposed to other risks that might increase the value of plan liabilities.

Lifetime Income for Participants

One of the concerns with DC plans is that participants could spend all of their assets in retirement and thus not have their DC account as a source of income for the later part of their retirement.⁶⁵ A June 2019 survey indicated that about 41% of nonretired Americans were concerned with outliving their retirement savings.⁶⁶ Although participants in DC plans have options to purchase annuities (either in their plan, if that is an option, or separately from an insurance company), a June 2016 survey by TIAA (a large provider of annuities) found that only about 14% of individuals had purchased an annuity.⁶⁷ Subject to adjustment as part of a realignment program, the composite plan proposal would provide monthly income in retirement for the life of the participant (and spouse, if married).

Pension Benefit Guaranty Corporation Insurance

Participants' benefits in composite plans would not be insured by PBGC. If the plan were to become insolvent and unable to pay benefits, PBGC would not provide financial assistance and participants would not receive their benefits.

Participants Benefits and Decreases in Plan Funding

Risks such as investment losses and changes to the assumptions used to value plan liabilities could negatively affect the value of plan liabilities, which would cause a plan's funding ratio to decrease, which in turn could lead to lower benefits for participants. The benefit reductions could be substantial, depending on the extent of the investment losses.

Investment Risk

In most DB plans, the plan sponsors must increase their contributions to make up for investment and other losses that cause the plan's funding ratio to fall below 100%. In DC plans, plan participants bear investment losses through smaller account balances. Participants in DC plans could increase their contributions if their contributions are below the annual contribution limit, which in 2020 is $19,500 per year ($26,000 if 50 years of age or older).⁶⁸ In composite plans, investment losses would be made up by a combination of proposed contribution increases and decreases in promised benefits. Unlike DB plans, there is no obligation for plan sponsors to increase contributions in the event of investment losses, and unlike DC plans, plan participants would be unable to make contributions to composite plans.

Other Risks

A plan's liabilities would increase (and its funding ratio would decrease) under the following circumstances: (1) if plan participants were to live longer and mortality tables were revised to reflect an increase in life expectancy, then a plan's funding ratio would decrease; (2) if there were changes to the actuarial assumptions used by the plan,⁶⁹ or (3) employers were to withdraw from the legacy plan. For example, if the discount rate that plans use to calculate the present value of future benefit obligations were to decrease, then the value of future benefit obligations would increase. A composite plan might have to address these, or similar, changes to the value of plan liabilities with the realignment program, which could include voluntary contribution increases and potentially mandatory benefit reductions.

Effect on Pension Benefit Guaranty Corporation

Because composite plans would not be covered by PBGC insurance, the plans would not pay premiums to PBGC. PBGC would not have any liability for benefits in a composite plan. In addition, it is possible that a legacy plan projected to become insolvent could become insolvent sooner because of the requirement that a composite plan would receive at least 25% of the combined contributions to the composite and legacy plans. This could leave PBGC with a larger liability for the insolvent legacy plan than would be the case if the plan were to receive its full contribution.

If the composite plan proposal were enacted, over time, PBGC would likely see its premium revenue decline. Although legacy plans would still be required to pay premiums to PBGC, PBGC's premium base would shrink. Over time, the number of participants in legacy plans would decline because (1) plan participants would die and (2) no new participants would receive benefits in the legacy plan. Lower premium revenue would leave PBGC with fewer resources from which to provide financial assistance to multiemployer plans.
