Pension Funds (United States) — NAICS 525110

An investor's primer. Figures are the latest available; forward-looking statements are worded as judgments, not facts.

---

1. Overview

A pension fund is a pool of money set aside to pay retirement benefits to a defined group — the employees of a company, the members of a union, or the public servants of a state or city. In the U.S. classification system (the North American Industry Classification System, or NAICS), code 525110 covers the funds themselves: the legal trusts, plans, and programs organized to hold retirement assets and pay benefits "exclusively for the sponsor's employees or members." [1]

Two things make this "industry" unusual to study — and they matter to both public-market and private investors:

• It is enormous but almost entirely non-commercial. Employer- and government-sponsored pension and retirement plans hold on the order of $27–30 trillion in assets [2][7]. Yet the funds are tax-exempt trusts and government systems, not profit-seeking businesses. Nobody "owns" a pension fund the way one owns a company.
• You cannot buy a pension fund — but pension funds are among the most important customers in finance. They are asset owners: giant allocators of capital that hire the firms an investor can own. So the ways to "invest in the pension industry" mean owning the companies that manage pension money, insure pension liabilities, or administer plans — not the plans themselves (Sections 4 and 10).

Why an investor cares even without ever buying a related stock: pension funds are the largest single class of long-term investors in public equities, corporate bonds, private equity, real estate, and private credit. Their allocation shifts move whole markets, their funding health is a fiscal question for states and a balance-sheet question for corporations, and the businesses that serve them form a durable, fee-earning ecosystem.

2. What it is and how it's structured

Scope of 525110. The code covers legally constituted pension funds, plans, and programs that provide retirement income to a sponsor's employees or members. [1] In practice that spans:

• Defined benefit (DB) plans — the sponsor promises a formula-based monthly benefit for life (usually based on salary and years of service) and bears the investment risk. Traditional corporate pensions and nearly all state, local, and federal government plans are DB. [2]
• Defined contribution (DC) plans — the sponsor (and often the worker) contributes to an individual account; the worker bears the investment risk and ends up with whatever the account is worth. 401(k), 403(b), and 457 plans, and the federal Thrift Savings Plan, are DC. [2]
• Single-employer, multiemployer (jointly union/employer-trusteed), multiple-employer, and pooled employer plans (PEPs) — the last two let unrelated employers share one plan, widening access for small businesses. [1]
• State and local government retirement systems, which are predominantly DB.

Pension funds are not owned like corporations. Assets are held in trust for participants and beneficiaries, with governance by trustees, investment committees, employers, unions, or government boards. External managers invest the assets but do not own them.

What 525110 EXCLUDES — and this matters, because the value chain around a pension fund is where the investable businesses live:

• Managing the money is a different industry: NAICS 523940, Portfolio Management and Investment Advice. When a pension hires an outside firm to run its portfolio, that firm sits here. [1]
• Underwriting the annuities a pension buys is insurance: NAICS 524113, Direct Life Insurance Carriers. [1]
• Health, welfare, and vacation funds are 525120; other employee-benefit and insurance funds are 525190; other pooled investment vehicles fall in the rest of the 5259 series. [1]
• Individual Retirement Accounts (IRAs) and personal trusts are not employer pension funds; IRA assets (about $18.7 trillion in 2025) are held at custodians and classified elsewhere. [2]

3. How big it is

Our federal business statistics for 525110 are essentially blank — on purpose, and that is the headline data point.

• The one federal business figure we hold as ground truth is the U.S. Small Business Administration (SBA) size standard: $40 million in average annual receipts — the ceiling below which a firm in this industry counts as "small" for federal programs. It is an eligibility threshold, not an estimate of industry revenue. [3]
• We do not have Census establishment counts, employment, payroll, or receipts for 525110. That is structural, not an oversight: the Census Bureau's County Business Patterns — the standard source for those numbers — explicitly excludes pension, health, welfare, and vacation funds (NAICS 525110, 525120, 525190). [4]

Why the undercount is structural. Pension funds are tax-exempt trusts and, overwhelmingly, government entities. A typical fund has few or no direct employees — the investing and administration are outsourced — and its "output" is not commercial sales. So the machinery that sizes most industries (establishments, jobs, payroll, receipts) omits this code or captures a tiny sliver. To size this industry you must use asset and participant data, not the business census. By those measures it is vast, viewed through several non-additive lenses:

• Total U.S. retirement assets reached about $49.1 trillion at year-end 2025 — roughly a third of all U.S. household financial assets. Of that, the employer- and government-sponsored pension universe closest to 525110 is about $27 trillion: roughly $14 trillion in DC plans (about $10 trillion of it 401(k) money), ~$10 trillion in government DB plans (federal, state, local), and ~$3 trillion in private-sector DB plans. IRAs and annuities make up most of the rest. [2]
• The Federal Reserve's Financial Accounts of the United States put total financial assets of private and public pension funds at about $29.6 trillion (Q1 2026) — a broader, differently scoped measure that is directionally consistent with the ICI figure above. [7]
• The Department of Labor's Form 5500 filings (the annual report every private plan files) counted ~836,800 private plans, ~155 million reported participant records, and $12.4 trillion in assets in the 2023 data — private plans only, excluding government systems and IRAs. DC plans are the overwhelming majority of that count, while active participants in private DB plans have fallen to roughly 11 million as those plans close to new workers. [5]
• The Census Bureau's Annual Survey of Public Pensions reports $5.99 trillion in state and local government pension assets in 2024, covering more than 36 million members and about $405 billion in annual benefit payments — the state/local DB slice specifically. [6]

These figures are complementary, not additive: they overlap and use different scopes, dates, and definitions. The consistent takeaway is a $27–30 trillion pool of retirement capital that ordinary business statistics barely register.

4. The investable universe

There is no "pension fund stock." The funds are trusts and government systems — you cannot buy shares in CalPERS any more than in the U.S. Treasury. What a public-market investor can own are the companies around pension funds: the asset managers who run the money, the custodians who safe-keep and service it, the record-keepers who administer accounts, the consultants/actuaries who advise plans, and the insurers who take pension liabilities off corporate balance sheets. What a private investor gains exposure to is being on the other side of pension capital — the private-equity, private-credit, real-estate, and infrastructure funds that pensions anchor as limited partners.

Public companies that earn money from pension capital (illustrative; U.S.-listed tickers). These are not pure-play 525110 businesses — pension work is one line in a broader financial-services model:

Note: custodians report assets under custody and/or administration (AUC/A) — client assets, not the firm's own — so separate that from assets under management (AUM) when judging revenue.

Big providers you cannot buy (privately held or member-owned, so no listed equity): Fidelity Investments (private), Vanguard (owned by its member funds), Capital Group and Wellington Management (private), Empower (owned by Great-West Lifeco), and TIAA / Nuveen (Nuveen is TIAA's asset-management arm). These are among the largest U.S. retirement managers and record-keepers, but there is no direct public equity in them.

The largest asset OWNERS (not investable — listed to show where the money sits): CalPERS (California Public Employees' Retirement System), ~$563 billion as of mid-2025; CalSTRS (California State Teachers'), ~$370 billion [10]; the New York State Common, New York City, Texas Teachers (TRS), and Florida (SBA) systems, each above $200 billion [11]; and the federal Thrift Savings Plan (TSP), the world's largest DC plan at roughly $1 trillion and about 7.2 million participants. [12]

Bottom line: to invest "in pensions," you buy the toll-collectors and risk-takers around the funds — asset managers (fee on assets), custodians and record-keepers (per-account and servicing fees), consultants (advisory revenue), and insurers (spread + longevity risk on annuities). To profit alongside pensions as a private investor, you co-invest in the same private-market funds pensions anchor.

5. How the money works

A pension fund is not a business that sells a product, so ordinary profit metrics don't apply. The right lenses are the funding equation of a defined benefit plan and the fee economics of the firms that serve it.

For a DB plan (the fund's own "P&L"):

• Assets vs. liabilities → funded ratio. A plan projects the benefits it owes decades out, discounts them to a present value (the liability), and compares that with assets on hand. Assets ÷ liabilities = the funded ratio. Above ~90% is generally considered healthy; below it, the gap is an unfunded liability the sponsor must eventually close. [19]
• The four levers of funded status: (1) contributions from the employer (and sometimes the worker); (2) investment returns; (3) benefit payments going out; and (4) the discount rate used to value liabilities. A higher assumed return / discount rate makes today's liability look smaller — which is why the assumption is so contested.
• The assumed rate of return is the single most important dial for public plans. The median public-plan assumption has drifted down from 8.0% in 2010 to about 7.0% today; every cut raises the reported liability but makes the plan's promises more credible. [13] Public plans (which discount at their expected return) and corporate plans (which must use market bond yields) live in different accounting worlds — the same benefit can look far cheaper on a government's books than a company's.
• Asset allocation drives the returns. Large public funds now hold roughly two-thirds in traditional stocks and bonds and about one-third in alternatives — private equity, real estate, hedge funds, and private credit — up from under 10% in alternatives two decades ago. [14] Chasing a ~7% assumed return through years of low bond yields is what pushed pensions into private markets, making them the anchor limited partners of the entire alternatives industry.

For the companies that serve pensions (their real profit engine):

• Asset managers earn a management fee — a percentage of AUM. Pension money is "sticky" (long horizons, slow to move), so it is prized: steady fee revenue, low churn.
• Custodians and record-keepers earn servicing and per-participant/per-account fees for holding and administering assets — a scale game where the largest, lowest-cost platforms win.
• Insurers earn on pension risk transfer (PRT): a corporation pays a lump-sum premium to hand its pension liability to an insurer, which issues group annuities and profits from the investment spread (earning more on the assets than it credits to annuitants) plus longevity risk (winning if retirees don't outlive the pricing). This is a spread-and-mortality business, not a fee business.

For an investor, the central distinction is between assets that generate service fees and liabilities that create financial risk: a record-keeper administers a huge pool it does not own; an insurer assumes liabilities and invests the premium; an asset manager earns fees but bears less direct liability risk.

6. What drives demand

• Demographics and aging. An aging workforce and lengthening lifespans expand the benefits owed and the assets that must back them. Longevity is both the reason pensions exist and a core risk (people living longer than assumed costs money).
• The DB-to-DC shift. Private employers have spent 40 years freezing and closing DB plans and pushing workers into 401(k)-style accounts, which now dominate the private-plan asset pool. [5] This shifts investment risk from employers to individuals and steadily grows demand for record-keeping, target-date funds, managed accounts, and advice — while shrinking the corporate DB pool that insurers want to buy.
• Automatic enrollment. The SECURE 2.0 Act of 2022 (Setting Every Community Up for Retirement Enhancement) requires many newly established 401(k) and 403(b) plans to automatically enroll eligible employees for plan years beginning after 2024, structurally lifting participation and contributions. [22]
• Interest rates. Rates are the master variable. Higher rates lower the present value of pension liabilities (good for funded status) but change the return outlook. The 2022–2024 rate rise is why corporate plans swung to surplus, and rate moves drive both funded status and the timing of PRT deals.
• DB de-risking. Companies increasingly want pension risk off the balance sheet, fueling demand for PRT, buy-ins and buy-outs, lump-sum offers, liability-driven investing (LDI), and outsourced chief investment officer (OCIO) services (Section 8).
• Small-employer pooling. PEPs and outsourced administration make plans more accessible to smaller employers, widening the addressable market for providers.
• Private-market allocation. Pension demand for ~7% returns underwrites private credit, real estate, infrastructure, and private equity — the reason large alternatives managers court retirement capital.
• Public-plan fiscal pressure. Underfunded state and city plans must raise contributions, which competes with schools, roads, and services — a political and fiscal driver that never goes away.

---

7. Regulation

Pension regulation is dense and splits sharply between private and public plans.

Private-sector plans are governed by the Employee Retirement Income Security Act of 1974 (ERISA), enforced primarily by the Department of Labor's Employee Benefits Security Administration (EBSA) and the IRS. ERISA sets fiduciary duties (trustees must act solely in participants' interest, diversify investments, and pay only reasonable expenses), funding rules, vesting rules, and disclosure via the annual Form 5500 filing. [5] Tax-qualification rules in the Internal Revenue Code — 401(a) (qualified plans), 401(k), 403(b), 457 — determine the tax breaks that make plans worth sponsoring, and SECURE 2.0 reshapes plan design, automatic enrollment, emergency savings, and retirement-income options. [22]

The Pension Benefit Guaranty Corporation (PBGC) is the federal backstop that insures private DB benefits (it does not insure ordinary DC plans). It protects the pensions of more than 40 million Americans and directly pays about 1.5 million people in failed plans. [15] It is funded by premiums, not taxpayers: for 2025 the single-employer flat-rate premium is $106 per participant, plus a variable-rate premium of $52 per $1,000 of unfunded vested benefits (capped per participant); the multiemployer flat premium is $39. PBGC's guarantee is capped — roughly $85,000–$90,000 per year for a single-employer retiree at age 65 in 2025 (indexed annually), and a much lower, un-indexed maximum (about $12,870 per year at 30 years of service) for multiemployer plans. [16]

Multiemployer rescue. The American Rescue Plan Act of 2021 created Special Financial Assistance (SFA) — one-time federal grants through PBGC to severely underfunded union multiemployer plans. Roughly $78 billion has been approved for about 161 plans covering ~1.8 million participants, with the program expected to reach 200-plus plans and over 3 million people. [17]

Public-sector plans are not covered by ERISA or PBGC. State and local plans are governed by state law, constitutional provisions, and funding policies, and report under Governmental Accounting Standards Board (GASB) rules (Statements 67/68), which since 2014 have forced fuller disclosure of unfunded liabilities on government balance sheets. Federal plans (civil service, military, TSP) are governed by their own statutes. This split is why public plans can use higher discount rates and carry larger reported gaps than corporations would be allowed.

Cybersecurity and participant-data protection are a rising regulatory and litigation front. Record-keepers, custodians, and asset managers share sensitive personal and financial data across service providers, and Government Accountability Office (GAO) reviews have flagged the resulting privacy and security risks. [23]

8. Competitive dynamics and consolidation

The funds don't compete with each other — but the industries around them are consolidating fast, and two structural trends dominate: corporations exiting the pension business and scale concentrating among a few mega-providers.

• The great de-risking (pension risk transfer). Rather than run a pension, more corporations pay an insurer to take it. The U.S. PRT market hit a near-record $51.8 billion of premium across ~785 transactions in 2024, then ran at $48.7 billion across 697 deals in 2025 — sustained near-record volume. [9] Marquee 2024 deals included IBM ($6.0B), Verizon ($5.9B), and Shell USA ($4.9B), all with Prudential; the market is concentrated, with about a dozen insurers writing over $1 billion each and Athene (Apollo) and Prudential the largest sellers. [9]
• Private equity's move into insurance. The most important structural shift is private-equity-backed insurers (Apollo/Athene, KKR/Global Atlantic, Brookfield) buying pension liabilities to gain permanent capital and feed their credit-origination machines — drawing regulatory scrutiny over offshore reinsurance and private-credit-heavy portfolios behind guaranteed annuities. [9]
• Asset-management scale. On the money side, scale wins: BlackRock, Vanguard, and State Street alone control on the order of $30 trillion, and the largest managers hold a growing share of global assets. [8] Pension mandates increasingly flow to the biggest index, LDI, and alternatives platforms.
• Record-keeper consolidation. DC administration has concentrated sharply. McKinsey estimates the ten largest DC record-keepers held 78% of industry assets in 2023, up from 56% in 2013, while record-keeping administrative fees fell roughly 25%–35% over the same decade — a cost-driven race that rewards the largest platforms (Fidelity, Empower, Vanguard, Principal, TIAA, Voya) and squeezes the rest. [21]
• Bundling. Winners increasingly combine record-keeping, investment products, custody, advice, insurance, and retirement-income tools, cross-selling across an employer relationship.
• The alternatives symbiosis. Public pensions, hunting their ~7% target, are the anchor capital of private equity, private credit, real estate, and infrastructure — making the largest funds the kingmakers of the entire alternatives industry. [14]

---

9. Risks

• Public-plan solvency. Aggregate state and local plans were about 80% funded in 2024, an improvement, but still carrying roughly $1.3–1.5 trillion in unfunded liabilities. [18][19] Chronically weak systems (Illinois, New Jersey, Kentucky, Chicago, Connecticut) face rising contributions that crowd out public services, and a single recession could widen the national gap sharply. [18]
• Return-assumption risk. Public plans assuming ~7% must actually earn it. Miss the target and the unfunded gap widens; the pressure to hit it is what drove pensions into illiquid, higher-risk alternatives whose valuations lag public markets. [13][14]
• Interest-rate whiplash. Rate moves swing funded status by hundreds of billions in a quarter. Corporate plans that de-risked into bonds are protected; those that didn't are exposed. (At the corporate end, the S&P 1500 aggregate was in surplus — roughly 109% funded, about $135B — after the rate rise. [20])
• Longevity and inflation. Retirees living longer or facing higher costs than priced is a direct hit to DB plans and to PRT insurers.
• Fee compression. Passive investing, competitive bidding, and litigation squeeze provider margins across asset management and record-keeping. [21]
• PRT counterparty risk. Once a pension is transferred to an insurer, retirees rely on that insurer's solvency and on state guaranty associations — not PBGC. The migration of these liabilities into PE-owned, offshore-reinsured, credit-heavy structures is a growing supervisory concern. [9]
• Litigation risk. Investment menus, fees, conflicts, disclosures, and participant outcomes routinely trigger ERISA class actions.
• Cybersecurity and privacy risk. Record-keepers and custodians hold sensitive personal and financial data; a breach or a failed platform can affect many plans at once. [23]
• Multiemployer and sponsor fragility. Even after the ARP bailout, some union plans face demographic decline; weak corporate sponsors or strained government budgets can impair contributions. [17]
• Concentration risk. A failed technology platform, custodian, insurer, or record-keeper can affect many plans simultaneously — the flip side of consolidation. [21]

10. How to invest, and the outlook

You cannot invest in a pension fund. You invest in the businesses around it — and you analyze them by revenue source, not headline assets. Separate AUM from AUC/A, distinguish recurring administration/custody fees from performance fees, and watch net flows, retention, fee rates, insurer capital, funded-status sensitivity, litigation, and cybersecurity.

Public-market routes:

• Asset managers (e.g., BlackRock BLK, State Street STT, T. Rowe Price TROW, Franklin BEN, Invesco IVZ) — own the fee stream on pension AUM. The economics are a percentage-of-assets fee; the risk is fee compression and flows to passive/low-cost products.
• Custodians and record-keepers (e.g., BNY BK, Northern Trust NTRS, Principal PFG, Voya VOYA, Alight ALIT) — own servicing and per-account fees tied to the DB-to-DC shift; a scale-and-cost game.
• Consultants/actuaries (Marsh & McLennan MMC, Aon AON) — own advisory, actuarial, and OCIO revenue.
• Life insurers active in pension risk transfer (e.g., Prudential PRU, MetLife MET, Apollo APO/Athene, Corebridge CRBG, Reinsurance Group RGA, Brookfield BAM) — own the spread-and-longevity economics of taking pensions off corporate books; arguably the highest-growth pension-linked segment. [9]
• Tickers, share prices, and valuation multiples belong to these operating companies, not to any pension fund.

Private-market routes:

• The most direct "pension exposure" for a private investor is being on the same side of the table as pensions — co-investing in the private equity, private credit, real estate, and infrastructure funds that pensions anchor as limited partners (the domain of managers like Blackstone BX, Apollo APO, and Brookfield BAM). Where large public plans commit, deal supply and pricing follow. These investments carry longer holding periods, more complex valuation, and less liquidity than public securities.
• Selling services into the ecosystem — administration, actuarial, fintech record-keeping, LDI/alternatives platforms — is a private-company growth lane driven by the same forces.

Near-term drivers to watch (forward-looking judgments):

• Interest rates. The direction of long rates keeps swinging funded status and PRT deal flow; a sustained higher-rate environment tends to keep corporate plans in surplus and eager to transfer risk.
• PRT momentum. With corporate plans well funded and de-risking structural, pension risk transfer looks positioned to stay near record volumes — a tailwind for annuity insurers, watched closely by regulators wary of the PE-insurance model. [9]
• DC growth. SECURE 2.0 auto-enrollment, PEPs, and the ongoing DB-to-DC shift favor record-keeping, target-date, managed-account, and retirement-income providers. [21][22]
• The alternatives allocation. Whether public plans keep pushing past one-third in alternatives to chase ~7% will shape private-market flows for years. [14]
• Public-plan reform. Contribution hikes, discount-rate cuts, and occasional benefit changes will grind on as underfunded states move toward solvency — slow, political, unavoidable. [18][19]

Editor's judgment: the retirement pool should stay durable across cycles, but asset growth will not automatically become earnings growth — fee pressure, regulation, market returns, and competition decide how much of the capital becomes profit. The best-positioned providers pair recurring administration or custody revenue with scalable investment products, retirement-income solutions, and technology.

The one-line takeaway: Pension Funds (525110) is a $27–30-trillion pool of long-term capital that federal business statistics barely count — not an industry you buy, but the customer base for the asset managers, custodians, insurers, and administrators you can buy, and the anchor capital behind the private markets you can invest alongside.
