3M Company Pension Plans
Private Sector
3M Company sponsors a single defined-benefit plan covering 56,773 active and retired participants — a sizeable workforce-and-retiree population. The combined plans are fully funded at 100.0% average funding ratio — a position where assets exceed accrued liabilities. Worst single-plan grade is A.
3M Company runs a generally well-funded pension book: 1 plans covering 56,773 participants, with combined assets of $12.4B against $12.4B in liabilities. Average funding ratio across the plans is 100%.
The plans on file for 3M Company include both active accrual plans (still adding benefits for current employees) and frozen plans (paying out earned benefits without new accruals). The worst grade among the plans is A — a useful flag for which specific plan to examine most closely. 3M Company operates in the Private Sector sector. Industry context matters for pension analysis: cyclical industries with volatile cash flow face harder funding patterns than steady-margin sectors, and the underlying ERISA and PBGC obligations are uniform across sectors regardless.
What the Numbers Mean for 3M Company
3M Company's combined pension footprint reports $12.4B in plan assets against $12.4B in accrued benefit obligations, producing an aggregate funding ratio of 100.0%. The unfunded gap of $560K is the dollar amount that would have to be contributed today, on top of expected investment returns at the assumed discount rate, to bring every plan to 100% funded.
3M Company's weakest plan still earns an A — every plan it sponsors sits in the healthiest tier of the Pension Health Score. The worst-grade signal is more useful than the average for a multi-plan sponsor — a healthy aggregate average can mask a single critically underfunded legacy plan inherited through acquisition. Participants in a specific plan should look at that plan's individual page rather than the company-level average.
3M Company is required under ERISA to file Form 5500 annually for each plan, with Schedule SB disclosing the actuarial valuation, funding target, and minimum required contribution. Schedule SB filings are publicly available through DOL EBSA. The Pension Benefit Guaranty Corporation separately publishes the federal guarantee that backstops these single-employer defined-benefit plans up to the statutory annual maximum.

How This Grade Is Calculated
Each plan's Pension Health Score combines three signals: funding ratio (50% of the composite), 3-year funding trend (30%), and PBGC risk level (20%). All three come directly from DOL Form 5500 filings and PBGC publications. The company-level "worst grade" surfaces the weakest plan in the sponsor's pension footprint — a useful signal for participants because legacy plans inherited through M&A often differ materially from the sponsor's active plans.

Frequently Asked Questions
How well-funded are 3M Company's pension plans?
3M Company's 1 pension plan is on average 100.0% funded. Fully funded status means the plans hold a position where assets exceed accrued liabilities. Total assets stand at $12.4B against $12.4B in accrued liabilities, leaving an unfunded gap of $560K.
Is 3M Company's pension protected by PBGC?
Corporate single-employer defined-benefit plans like the ones 3M Company sponsors are insured by the Pension Benefit Guaranty Corporation up to a statutory annual maximum that varies by retirement age. PBGC publishes the current guarantee tables at pbgc.gov. Multiemployer plans, if applicable, fall under a separate PBGC insurance program with a much lower per-participant guarantee. The protection is real but capped — high earners with benefits above the PBGC maximum can lose the portion above the cap if a plan terminates underfunded.
What does the A grade mean for 3M Company?
3M Company's weakest plan still earns an A — every plan it sponsors sits in the healthiest tier of the Pension Health Score.
How many of 3M Company's plans are underfunded?
Of 1 plan sponsored by 3M Company, 1 is fully funded (100%+) and 0 fall below the 80% actuarial benchmark. Participants in any underfunded plan should request the most recent Annual Funding Notice, which is mailed annually under ERISA Section 101(f) and discloses the plan's adjusted funding target attainment percentage.
