PBGC's $62B Surplus Resets the Actuarial Case for Premium Reform

The PBGC single-employer program closed FY2025 with a $62.2 billion surplus: $152.3 billion in assets against $90 billion in liabilities (PBGC 2025 Annual Report). Total underfunding across all 22,000 insured single-employer plans stands at roughly $85 billion. The reserve now exceeds nearly three-quarters of its realistic maximum exposure, and current premiums project it past $100 billion within a decade. That arithmetic is what pension actuaries and employer advocates mean when they say the premium structure has become indefensible on its own terms.

How Premium Income Built a Reserve Larger Than the Risk It Covers

PBGC single-employer plans pay three types of premiums under ERISA Section 4006. The flat-rate premium, charged per covered participant regardless of plan funded status, hit $111 for 2026 plan years, up from $106 in 2025 and more than triple the $35 rate in effect in 2012 (PBGC Premium Rates Factsheet, 2025). The variable-rate premium, which does scale with underfunding, currently charges $52 per $1,000 of unfunded vested benefits with a per-participant cap of $751, though Congress froze it at $52 under Section 349 of the SECURE 2.0 Act. A third component, the distress termination premium of $1,250 per participant for three years, applies only when a financially troubled sponsor cannot support a standard termination and must transfer the plan to PBGC.

Plan Year	Flat Rate (per participant)	Variable Rate (per $1,000 UVB)
2012	$35	$9
2015	$57	$24
2018	$74	$38
2020	$83	$45
2022	$88	$48
2024	$101	$52
2025	$106	$52
2026	$111	$52

Congress designed these escalations not from actuarial reserve requirements but from budget deficit-reduction logic. The Multiemployer Pension Reform Act of 2014 and the Bipartisan Budget Acts of 2013 and 2015 each used PBGC premium increases as pay-for mechanisms, treating premium income as federal revenue that offset other spending. The flat-rate has compounded at roughly 8.5% per year since 2012. No actuarial study drove those numbers; they were set to fill a budget gap, and the indexing provisions locked in the compound growth indefinitely.

PBGC currently pays $6.4 billion in retirement benefits annually to nearly 926,000 retirees in PBGC-trusteed plans, covering 18.4 million workers and retirees across approximately 22,000 active single-employer plans (PBGC 2025 Annual Report, January 2026). Premium income and investment returns on the growing asset base have consistently outpaced that outflow. With $152.3 billion in assets against $90 billion in liabilities, the program carries a 169% funded ratio on its own insurance liabilities.

The Reserve-to-Exposure Calculation That Makes the Academy's Case

Reviewing PBGC annual reports from 2017 through 2025, the single-employer program's surplus trajectory was clear well before the $62.2 billion number was published: the gap between realized premiums and actuarially justifiable levels has been widening since at least 2019, and the reform discussion has moved from whether to when in practitioner conversations. The FY2025 report makes the numbers impossible to ignore.

Insurance reserves exist to cover expected future losses plus a risk margin for adverse scenarios. The actuarial test for PBGC's reserve adequacy has to start with a realistic loss estimate, not the face value of every underfunded plan in the country. The American Academy of Actuaries published an analysis in 2026 framing the core arithmetic: total underfunding across all PBGC-insured single-employer plans stood at roughly $85 billion as of 2024 (American Academy of Actuaries, 2026). Of that $85 billion, PBGC will not become responsible for most of it. The vast majority represents ongoing sponsors with the capacity to fund the shortfall over time; only plans whose sponsors become financially distressed and cannot support a standard termination transfer liabilities to PBGC.

The PBGC's $62.2 billion surplus already covers approximately 73% of total system underfunding before the agency collects another dollar of premium. More to the point, its own Projections Report shows the surplus remaining positive in every modeled scenario across the 10-year horizon, including stress tests that combine major market downturns with historically high claims volumes. The program is projected to remain solvent indefinitely with no model scenario showing assets becoming fully depleted during the projection period (PBGC Projections Report, 2025).

Bruce Cadenhead, the American Academy of Actuaries Vice President of Retirement, stated the problem directly: "The single-employer program's growing surplus due to the current, legally mandated SE premium structure, continues to be far out of proportion to the SE system's risk." (American Academy of Actuaries, 2026)

The 10-year trajectory makes the imbalance structural rather than cyclical. PBGC's own projections show the single-employer surplus exceeding $100 billion within the decade under current premium rates. The Congressional Research Service primer on the surplus (CRS IF12951, 2025) confirmed the 10-year average projected position rising from the $54 billion level at the time of its publication to approximately $71.6 billion by FY2033 under a baseline scenario, with the upside case considerably higher. The difference between those CRS projections and the $62.2 billion already achieved in FY2025 reflects how rapidly the surplus grew through FY2025, making the projections look conservative within two years of their publication.

The PRT Flywheel: Why the Premium Level Compounds Its Own Problem

PBGC premiums do not exist in isolation from the broader pension market. At $111 per participant in flat-rate charges annually, plus variable-rate premiums for underfunded plans, plus actuarial valuation fees, trustee costs, PBGC filing costs, and investment management fees, the total annual cost of maintaining a frozen defined-benefit plan has become a de-risking accelerant. A sponsor whose plan holds 2,000 participants faces $222,000 in flat-rate PBGC premiums alone before adding any of those overhead costs.

The result is visible in the PRT market data. Full-year 2025 pension risk transfer sales reached approximately $49 billion in premium volume, the third-strongest year in market history after the record $51.8 billion in 2024 (LIMRA, 2026). Each buyout transaction permanently removes a group of participants from the PBGC count. By definition, only funded plans can execute settlement-cost buyouts at competitive pricing. A plan at 80% funded status cannot afford to purchase an annuity at 101% of accounting liability. The plans exiting via pension risk transfer are disproportionately the well-funded ones, drawn out by premium economics that make termination cheaper than continuation. The plans remaining in the PBGC pool are disproportionately those that cannot afford to leave.

This is a recognizable adverse selection spiral. Elevated premiums push the healthiest risks out of the insurance pool. The remaining pool gradually concentrates in higher-risk exposures. That deteriorating pool profile then reinforces the political argument for maintaining elevated premiums. The mechanism is self-sustaining, and it operates against the PBGC's own statutory objective of encouraging the continuation of defined-benefit plans.

The Academy specifically cited high premiums as a factor "discouraging employers from continuing to offer benefits through defined benefit plans" (American Academy of Actuaries, 2026). Employers that have maintained frozen DB plans through two decades of escalating costs are finding the premium trajectory alone justifies termination for plans above roughly the 105% funded threshold, even before accounting for the favorable PRT buyout pricing environment. The breakeven analysis at current DB funded status levels shows premium drag alone often justifies PRT above 105% funded, and every year premiums rise that threshold falls.

The Multiemployer Pivot: The Cross-Subsidy Argument Has Expired

For years, discussions about single-employer premium levels carried an implicit backstop argument: PBGC as an agency needed a strong financial position, and the single-employer surplus provided cushion against the multiemployer program's deep deficits. The logic was never legally sound, since ERISA prohibits funds from flowing between the two programs. It was politically coherent. That argument has now expired on its own facts.

The PBGC multiemployer program closed FY2025 with a $2.6 billion positive net position, holding $4.9 billion in assets against $2.3 billion in liabilities (PBGC 2025 Annual Report, January 2026). At the end of FY2020, the same program carried a deficit of approximately $65.2 billion, and PBGC's own projections showed it becoming insolvent around 2026 without congressional intervention. Eleven million participants in roughly 1,300 plans faced a realistic risk of benefit cuts that the multiemployer insurance fund could not cover.

The rescue came not from single-employer premium income but from direct congressional appropriations through the American Rescue Plan Act of 2021. The ARPA Special Financial Assistance program had by May 2026 approved $77.9 billion in assistance for 161 plans covering 1.8 million participants (PBGC SFA Program, May 2026). ARPA funded that assistance through general federal revenues. No dollar of single-employer premium income transferred to the multiemployer program, as ERISA does not permit it.

The multiemployer program is now projected to remain solvent beyond 2063, the final year of PBGC's projection period, in most modeled scenarios. The $65-billion-plus swing from deficit to surplus was accomplished through legislative action at essentially zero cost to single-employer plan sponsors. The cross-subsidy justification for elevated SE premiums did not hold as a matter of law when the multiemployer program was in deficit, and it holds even less as a policy argument now that the multiemployer program has been recapitalized independently.

Reform Options and the Budget Scoring Obstacle

The American Academy of Actuaries outlined several approaches Congress could take, noting that "a combination of changes could result in a significant reduction in premiums, be consistent with the PBGC's mission, and remove premiums as a significant impediment to the ongoing maintenance of defined benefit plans" (American Academy of Actuaries, 2026). The principal options differ in their actuarial logic, their legislative complexity, and their ability to survive the Congressional Budget Office's scoring process.

Premium freeze and surplus runoff. The most operationally direct path: freeze the flat-rate premium at its current $111 level and let the $62.2 billion surplus absorb future losses as they materialize. The flat-rate freeze requires changing the indexing provision in ERISA Section 4006(a)(3)(A) rather than overhauling the entire premium structure. PBGC's projections show the program remaining solvent indefinitely even with a freeze, making this actuarially defensible. It does not return value to plan sponsors, but it stops further accumulation.

Risk-based premium redesign. Replace the flat-rate structure with a per-participant premium that scales with funding level, so well-funded plans pay near zero and severely underfunded plans pay a higher actuarially justified rate. The variable-rate premium partially captures this logic, but its freeze removed the risk-pricing dimension from the structure. A redesigned flat-rate that falls to nominal levels for plans above 100% funded would directly address the adverse selection incentive: sponsors who maintain well-funded plans would no longer be cross-subsidizing sponsors whose plans are at risk of termination.

Surplus distribution. Returning surplus to plan sponsors via premium credit, refund, or temporary holiday would most directly address the economic harm to sponsors who have overpaid relative to actuarial risk. This requires ERISA modification, since the statute currently limits PBGC's authority to use its funds for purposes other than paying insurance benefits. The targeting question is also substantive: any distribution mechanism must be structured to avoid rewarding the sponsors whose plans created the most risk while discouraging further plan maintenance by well-funded sponsors who receive a refund and then terminate.

Budget scoring reform. This is the enabling constraint that underlies all other options. PBGC premium income is recorded as federal revenue under Congressional budget rules established by the Budget Enforcement Act. Reducing premiums scores as a revenue loss requiring an offsetting revenue increase or spending cut. Congress has used premium increases as deficit-reduction tools precisely because they score as revenue, and reversing that direction carries a formal scoring cost the budget committees must address. The Academy specifically identified reforming how premiums are handled for budget scoring purposes as a prerequisite for structural premium reform. Without that change, any premium reduction requires an offset that makes the legislation harder to advance.

No major PBGC premium legislation is moving in the current Congressional session. The reform conversation has advanced significantly in 2026, with the Pensions and Investments coverage of employer advocates and actuarial professionals intensifying pressure, but converting that pressure into legislation requires navigating both the budget scoring constraint and the competing interests of plan sponsors, unions with interest in multiemployer program stability, and Congressional members who have used premium increases as a budget revenue source.

Planning Considerations While Reform Stalls

Actuaries advising plan sponsors in 2026 and 2027 should plan around the current premium structure remaining in place. That means the annual cost of inaction continues to compound. A plan with 3,000 participants pays $333,000 in annual flat-rate premiums before the variable-rate charge applies. Over a 10-year horizon at a 5% discount rate, the present value of that flat-rate stream alone is approximately $2.6 million for a plan with no underfunding exposure. Add administrative costs, investment management, and actuarial fees, and total ongoing plan costs for a 3,000-participant plan typically run $500,000 to $700,000 per year. The present value of a decade of those costs, $3.9 million to $5.4 million, often exceeds the settlement premium for a funded plan executing a PRT buyout at current competitive pricing.

The premium reform timeline also interacts with contribution strategy. Sponsors who have been maintaining a funded ratio slightly below 100% to minimize variable-rate exposure face a different calculus than sponsors targeting 110% to maximize de-risking option value. If reform ultimately delivers premium relief, sponsors who have maintained high funded status would benefit most from a risk-adjusted redesign (since well-funded plans would pay minimal premiums under a reformed structure) while sponsors who chose a lower funded ratio to minimize current variable-rate charges would see limited incremental benefit. The actuarial argument for maintaining strong funded status is, if anything, strengthened by a reform environment that is moving toward risk-based pricing.

For sponsors evaluating full plan termination versus a partial buyout strategy, the PBGC premium economics now favor acting under the current structure rather than waiting for potential reform. Reform, if it comes, would reduce ongoing premiums but would not refund premiums already paid. A sponsor who waits three years for legislation before executing a PRT has paid three additional years of $111 per participant in flat-rate charges with no recovery. The economic asymmetry between acting now and waiting for a premium reduction that may not arrive runs strongly in favor of current-year de-risking decisions for plans that are financially ready.
