General Motors executed the largest voluntary pension buyout in U.S. history in 2012 and followed it with one of the largest pension risk transfers ever completed. If you are a GM salaried retiree, a deferred vested participant, or a UAW hourly retiree trying to understand your options in 2026, the landscape is more complicated than it looks from the outside. Here is the full picture.
The 2012 landmark pension transfer
In June 2012, GM announced two simultaneous actions covering its salaried retiree pension obligations. First, it offered a voluntary lump sum to over 100,000 eligible salaried retirees, totaling approximately $26 billion in buyout offers. Roughly 44% of eligible retirees accepted, taking the cash and rolling it to IRAs or taking it as taxable income.
Second, for the approximately 42,000 salaried retirees who declined the lump sum, GM purchased a group annuity from Prudential Insurance Company. Prudential assumed the obligation to pay those retirees their monthly benefit for the rest of their lives. GM's pension liability for those individuals transferred off its balance sheet permanently.
A follow-on transaction in 2013 covered an additional tranche of salaried retirees. Combined, the 2012 and 2013 transactions removed more than $26 billion in pension obligations from GM's balance sheet and moved tens of thousands of retirees from PBGC-backed coverage to Prudential-backed coverage.
Who still has GM pension options
After the 2012 and 2013 transactions, the landscape split into three groups:
Salaried retirees annuitized through Prudential: These retirees no longer have a relationship with the GM pension plan. Their monthly payments come from Prudential. They cannot elect a lump sum from GM because GM no longer holds their obligation. Their protection is Prudential's financial strength and state insurance guaranty associations, not the PBGC.
Deferred vested salaried participants: Former GM salaried employees who left before retirement age and have not yet begun collecting. If they were not included in the 2012 or 2013 transactions (many were not), their benefit remains in the GM plan. They may be eligible for future lump sum windows when GM opens them.
UAW hourly retirees: Covered by a separate UAW-negotiated plan. The 2012 transactions were salaried only. UAW hourly retirees receive their flat-dollar monthly benefit from the GM hourly plan. Most do not have a lump sum election option.
The UAW hourly plan: how it works
GM's UAW-represented hourly workers have a defined benefit that pays a flat dollar amount per year of credited service. The rate has increased through successive UAW contracts. The current rate is approximately $56 to $60 per month per year of service, depending on specific job classification and contract vintage.
A 30-year UAW hourly worker at $58 per month per year earns $1,740 per month, or $20,880 per year. This stacks on Social Security. UAW hourly workers do pay into Social Security during their GM employment, so they accrue Social Security credits alongside their pension benefit.
The UAW hourly plan does not offer a lump sum at retirement. The benefit is a guaranteed monthly annuity for life. Some early-out windows negotiated through UAW contracts have included enhanced separation payments, but these are distinct from pension lump sums calculated under the IRS 417(e) formula.
The salaried plan formula
For salaried participants still in the GM plan, the benefit formula uses final average pay and years of service. The specific multiplier and averaging period are detailed in the plan documents. GM's salaried plan was a relatively generous traditional defined benefit before it was frozen: long-service salaried employees with strong final salaries accumulated substantial monthly benefits.
The plan stopped accruing benefits for most salaried employees before GM's 2009 bankruptcy reorganization. The reorganization preserved retiree pension benefits; the plan has been in runoff since then, paying existing earned benefits with no new entrants accruing credits.
How to calculate your GM lump sum: the IRS 417(e) formula
Any lump sum GM offers to eligible participants must be calculated using the IRS 417(e) present-value methodology. This formula discounts each future monthly payment back to today's dollars using three segment rates tied to corporate bond yields.
The 2026 segment rates (from November 2025 IRS data):
- Segment 1 (payments in years 1-5): 5.03%
- Segment 2 (payments in years 6-20): 5.35%
- Segment 3 (payments in years 21 and beyond): 5.57%
GM's plan documents specify whether the plan uses the November, October, or August lookback month. Use the rates from your actual election notice rather than assuming November rates apply. The lookback month difference can shift your lump sum by several thousand dollars.
To calculate your present value: take your monthly benefit, apply an actuarial life expectancy based on your age and IRS mortality tables, and discount each payment at the appropriate segment rate. The pension lump sum calculator on this site does this in seconds. Enter your monthly benefit, your age, and the rates from your plan documents.
A worked example: a GM salaried participant with a $4,000/month benefit, age 65, 20-year life expectancy. At 2026 rates (5.03%, 5.35%, 5.57%), the present value is approximately $593,000. Under the November 2021 rates (0.85%, 2.36%, 3.08%), the same benefit calculated to roughly $840,000. That is $247,000 of lump sum value that evaporated between 2021 and 2026 with no change to the underlying pension.
The PBGC guarantee
For salaried participants whose benefits remain in the GM plan (not annuitized through Prudential), PBGC coverage applies. If GM's pension were ever terminated in an underfunded state, PBGC covers benefits up to its guarantee limit: approximately $7,107 per month for a retiree aged 65 in 2026. Most GM salaried retirees receive benefits well within this limit, making PBGC coverage effectively full protection.
The $7,107 limit adjusts annually. It is substantially lower for early retirees and for those taking reduced survivor benefit forms. Check the PBGC's published guarantee limits for your specific age and form of payment.
For the roughly 42,000 retirees whose pensions were transferred to Prudential in 2012 and 2013, PBGC coverage ended at the time of transfer. Their protection is Prudential's AM Best A+ financial strength rating and state insurance guaranty association coverage, which typically protects annuity contracts up to $250,000 in present value.
Lump sum vs. monthly payment: the breakeven math
The breakeven age is the point at which cumulative monthly payments catch up to the lump sum. At 2026 rates, most GM salaried retirees hit their break-even between ages 80 and 83.
If you are 65 and expect to live to 88, the annuity pays more over your lifetime by a substantial margin. If you are 65 with a terminal diagnosis or serious chronic illness, the lump sum's flexibility matters more than the annuity's longevity protection.
Key questions for the decision: do you have a surviving spouse who needs continued income? Do you have other guaranteed income sources (Social Security, other pensions) that cover basic expenses? Are you a disciplined investor who will not panic-sell during market downturns? Your answers shape whether the lump sum's flexibility or the annuity's guarantee is more valuable to your specific situation.
Use the pension lump sum calculator to find your break-even age, then see the General Motors pension guide for employer-specific context. A fee-only fiduciary advisor can model your specific numbers with your actual plan documents. Most charge $200 to $500 for a one-time analysis with no incentive to push you toward any particular product.
