What it means
CalPERS collects contributions from public employers and from employees, invests that money for decades, and then pays retirement and health benefits to members. It runs a defined benefit plan, which means the pension is promised by a set formula based on salary and years of service rather than depending on whatever the investments happened to earn.
The fund and its participating employers, not the individual member, carry the investment risk. Because CalPERS invests on such a scale, it is a shareholder in thousands of listed companies and a large buyer of bonds, property, infrastructure and private equity.
When it publishes a view on executive pay, board independence or climate disclosure, other large investors often move the same way, an influence sometimes called the CalPERS effect. For the finance team of a listed company, it can be one of the loudest voices in a governance decision.
The financial health of a fund like CalPERS is tracked through its funded ratio, which compares the assets held today with the value of the benefits already promised. When that ratio falls, participating employers are asked for higher contributions, and those increases land straight in city, county and school district budgets.
This is why pension funding turns up as a line item in local government finance debates rather than only in investment reports. CalPERS is a public sector plan, so it is governed by California statute and supervised by its own board rather than by the federal rules that cover private company pensions.
It also operates one of the largest employer-sponsored health purchasing programmes in the country, so it buys medical cover as well as investing assets. Treating it as purely an investment fund misses half of what it does.
For a manager without a finance background, the useful distinction is that CalPERS plays two separate roles in any conversation. It is a long-term owner of company shares, and it is a claim on public payrolls that shapes municipal budgets.
Working out which role is under discussion usually clears up most of the confusion in the room.
In practice
Real-world examples.
Example
A California city finance director is told the employer contribution rate will rise from 30% to 34% of payroll after the latest actuarial valuation. On a $50 million payroll that moves the annual pension cost from $15 million to $17 million. She freezes two vacant posts to fund the difference without cutting services.
Example
The investor relations lead at a listed manufacturer learns that CalPERS intends to vote against the executive pay package at the annual meeting. Within days two proxy advisers publish the same recommendation. The remuneration committee agrees to add a performance condition before the vote is held.
Example
A new analyst at a school district explains to teaching staff that their pension sits with CalSTRS, the separate California teachers' fund, while the bus drivers and office staff in the same building are CalPERS members. The two funds have different contribution rates and different valuations. Budgeting for both correctly avoids a material error in the district's staffing forecast.
Formula
Calculation
Funded ratio = Plan assets / Actuarial accrued liability.
Assume a plan holds $480 billion of assets and has an actuarial accrued liability, meaning the present value of benefits already promised, of $600 billion.
Funded ratio = $480 billion / $600 billion = 0.80, or 80%.
Unfunded liability = $600 billion - $480 billion = $120 billion.
If employers are required to close that gap over 20 years and investment returns are set aside for simplicity, the catch-up contribution is $120 billion / 20 = $6 billion per year. Spread across a participating payroll of $60 billion, that is an extra 10% of payroll on top of the normal cost of benefits being earned this year.Case study
Seen in the real world.
Harbour Vale is an illustrative California city of about 90,000 residents, used here as a fictional example rather than a real municipality. Its finance team received an actuarial valuation showing the share of its pension promises that were funded had slipped from 78% to 71% after two weak investment years. The employer contribution was scheduled to rise by roughly $2.4 million a year over three years.
The city manager's first instinct was to describe the change as a surprise bill from the pension fund. The finance director reframed it instead as the cost of benefits already earned by staff who were already working, simply measured more accurately. That framing changed the conversation from blame to a funding plan.
Harbour Vale adopted a three-part response in this illustrative scenario: a dedicated pension reserve funded from one-off land sale proceeds, a slower hiring plan in administrative functions, and a quarterly report to council showing the funded ratio alongside the contribution forecast. The gap did not close in a year, but the council stopped being surprised by it.
Watch out
Common mistakes.
- Assuming CalPERS pays pensions out of current tax revenue, when most of the money paid each year comes from investment returns and from contributions collected and invested years earlier.
- Reading a funded ratio below 100% as a sign that pensions will not be paid, rather than as a long-term funding gap that employers close over decades.
- Confusing CalPERS with CalSTRS, the separate fund for California teachers, which produces real budgeting errors for school districts that employ members of both.
Questions
People also ask.
Who actually contributes to CalPERS?
Both public employers and their employees contribute, with employer rates reset after each actuarial valuation of the plan.
Does CalPERS only buy shares?
No, it spreads money across listed shares, bonds, private equity, property and infrastructure to reduce reliance on any single market.
Why do company boards care what CalPERS thinks?
Because it is a large long-term shareholder whose published voting intentions frequently influence how other institutional investors vote.
