Frozen Pension Plan: What It Means and Your Options at Retirement

Tens of millions of Americans are covered by frozen defined-benefit pension plans — pensions where accruals stopped years ago after their employer froze the plan. IBM, GE, Boeing, Lockheed Martin, and hundreds of other major employers made this move. If your pension is frozen, your benefit is fixed at what you earned before the freeze date. But the lump sum vs. annuity decision at retirement is identical to an active plan — with one critical difference that changes how you should think about timing.

What "Frozen" Actually Means

A pension freeze is an employer action that stops future benefit accruals — it does not take away benefits you have already earned. ERISA strictly prohibits retroactive reduction of accrued benefits.¹ The benefit you earned before the freeze date is permanently protected.

There are two types of freezes:

Hard Freeze (Full Freeze)

All benefit accruals stop for everyone in the plan — new hires cannot join, and existing participants earn no additional pension benefit regardless of continued service. Your benefit is fixed at whatever you accrued through the freeze date. IBM hard-froze its traditional defined-benefit pension for most employees by the end of 2007–2008 after closing the plan to new entrants several years earlier.³

Soft Freeze (Closed Plan)

No new employees can join the plan, but existing participants continue to accrue benefits under the original formula. If you were already in the plan before the freeze date, your benefit continues growing with service and salary. New employees hired after the freeze date are placed into a 401(k) or other DC plan instead.

What Does Not Change After a Freeze

• Your vested benefit is fully protected. The accrued benefit as of the freeze date cannot be reduced.
• PBGC coverage continues. The PBGC insures single-employer frozen plans the same as active plans. The 2026 maximum guaranteed benefit is $7,789.77/month at age 65 for a straight-life annuity.²
• Your distribution options remain. At retirement, you still elect between a lump sum (if the plan offers one) and the various annuity forms — life-only, joint-and-50%, joint-and-75%, joint-and-100%, period-certain combinations.
• Spousal consent rules apply. ERISA §205 requires spousal consent for any election other than the qualified joint-and-survivor annuity, regardless of freeze status.
• The plan continues to receive required funding contributions until the employer terminates it through a formal PBGC process.

How the Lump Sum Is Calculated on a Frozen Plan

Lump sums from frozen defined-benefit plans are calculated the same way as active plans — using the IRS §417(e) minimum present value segment rates. These three rates discount your future monthly payments to a present value.

As of April 2026, the §417(e) segment rates are 4.75% / 5.25% / 5.84% (IRS Notice 2026-26).⁴ These rates are substantially higher than the 2021 trough (under 1% / 2% / 3%), which means lump sum offers in 2026 are considerably smaller than they would have been at the same benefit level five years ago.

Example: A frozen pension paying $3,500/month at age 65 might have been worth $800,000+ as a lump sum in 2021. At 2026 segment rates, the same $3,500/month generates a lump sum closer to $520,000–$580,000 depending on the plan's look-back period.

The critical insight: the lump sum value of your frozen benefit still fluctuates with interest rates even though the monthly benefit amount itself is locked. If rates fall 1 point, your lump sum offer grows — without you doing anything or earning any more service credit.

This means rate timing is arguably more important for frozen pension holders than for active-plan participants, because there is no offsetting accrual growth to consider. With an active plan, the question is "do I earn enough in additional accrual by waiting to offset the interest-rate risk?" With a frozen plan, the accrual side of that equation is zero — it's a pure rate timing question.

Major Employers with Frozen Pension Plans

The share of Fortune 500 companies offering a traditional defined-benefit pension has fallen from 59% to 16% over the past 25 years.⁵ Many of the remaining pensions are frozen. A partial list of major employers with frozen DB plans:

• IBM. Hard-froze its traditional defined-benefit plan by end of 2008. In 2023, IBM introduced a new Retirement Benefit Account — a cash balance plan within the legacy structure for active employees — but the original accrual formula remains frozen.³
• General Electric. Froze pension benefit accruals for approximately 20,000 U.S. employees in 2019 as part of a multi-year effort to reduce a multi-billion-dollar funding deficit.⁶
• Boeing. Abandoned the traditional pension structure for IAM machinists in 2014 as part of a contract settlement; prior accruals remain frozen for that employee group.⁷
• Lockheed Martin. Froze benefit accruals for salaried employees, transitioning to enhanced 401(k) contributions.⁵
• Hundreds of other mid-size and large employers across manufacturing, healthcare, financial services, and utilities have taken similar actions, particularly following the 2008–2009 financial crisis when low interest rates dramatically increased pension liabilities.

If you're unsure whether your plan is hard-frozen or soft-frozen, the Summary Plan Description (SPD) — which your plan administrator must provide under ERISA §104(b) — will state the freeze date and current accrual formula. You can also check Form 5500 filings via the DOL ERISA search database.¹

Frozen Plan vs. Plan Termination: Two Very Different Things

Participants often conflate a freeze with a termination. They are legally distinct:

A freeze can precede a termination — the employer freezes first, then terminates years later once the plan is better-funded. But a freeze itself leaves all your rights intact and your benefit fully protected by PBGC. PBGC pension insurance guide →

Checking Your Frozen Plan's Funding Status

Employers often freeze plans specifically because they are underfunded — meaning the plan assets are less than the projected benefit obligations. Underfunded plans carry a risk that, if terminated in distress, your benefit may be limited to the PBGC guarantee cap.

Two ways to check:

• Annual Funding Notice. Plans with 100+ participants must send an annual funding notice to participants. It shows the plan's funding percentage (100% = fully funded). If your plan has been chronically below 80%, that is a risk flag.
• Form 5500. Filed annually with the DOL. Schedule B (actuary's certification) shows funding levels. Search at the DOL ERISA online database (dol.gov).

If your plan is underfunded and your monthly benefit would exceed the PBGC cap ($7,789.77/month at age 65), the excess has no federal backstop. In that case, taking the lump sum — which transfers the solvency risk to you — may be structurally preferable to an uncapped annuity from a financially stressed plan. This is the opposite conclusion you'd reach with a well-funded pension from a financially stable employer.

The Retirement Timing Question With a Frozen Plan

With an active pension, retiring later means more service credit, a higher monthly benefit, and possibly a larger lump sum. The question is whether the incremental accrual is worth another year of work.

With a frozen plan, retiring later adds zero additional pension benefit. Your monthly annuity at age 62 is the same as at age 65 or 67. The only things that change with time are:

• Interest rates — which change your lump sum size
• Your other savings (401k, IRAs) — which continue to grow
• Your health status and life expectancy — which affect the longevity calculation
• Your eligibility for Social Security — the delay-to-70 strategy interacts differently when you have a fixed frozen pension rather than a growing one

This is a meaningful asymmetry. If you have a frozen pension and are evaluating whether to work another 2 years, the pension side of the retirement equation is essentially neutral — it neither rewards nor penalizes you for timing. Your decision framework should focus on 401(k) growth, Social Security timing, and whether the current interest rate environment makes the lump sum relatively large or small.

Roth Conversion Window Before the Annuity Starts

Because a frozen pension provides a fixed, predictable annuity amount, you can model your future income picture precisely. This makes the Roth conversion window (the years between retirement and when your annuity or Social Security starts) especially valuable to plan around.

A retiree with a $2,800/month frozen pension starting at age 65, plus $2,400/month of Social Security starting at age 70, has a 5-year window from 65 to 70 where their only taxable income is the $33,600 annual pension. In a standard scenario, that leaves substantial room in the 22% bracket to do Roth conversions from the IRA rollover before Social Security income narrows that window permanently.

What to Do Next

Frozen pension holders face the full complexity of the lump sum vs. annuity decision — without the benefit of ongoing accrual growth to simplify the math. If your benefit exceeds the PBGC guarantee cap, if your plan is underfunded, or if you're trying to optimize Roth conversions around a fixed annuity income stream, these are exactly the scenarios where a fee-only advisor who specializes in pension decisions adds the most value.
