Pension funds vote their shares through a chain: a written voting policy sets the rules, an in-house team or external managers cast the ballots, and proxy advisors supply research and recommendations. The largest funds increasingly vote independently from their own guidelines rather than relying solely on advisors or delegating to managers.
A large pension fund might cast votes at tens of thousands of company meetings in a single year. Behind that volume sits a surprisingly intricate machine — one that determines whether a fund's stated values actually translate into the way its shares are voted. Understanding how pension funds vote is the difference between taking a fund's stewardship claims on faith and knowing whether they hold up.
The voting chain, from policy to ballot
A pension fund's vote is the output of a chain with four links.
The first link is the voting policy (often called proxy voting guidelines). This is the written rulebook setting out how the fund will vote on the recurring items that appear on almost every ballot: director elections, say-on-pay, auditor ratification, capital authorisations and shareholder proposals. A good policy makes voting consistent across thousands of meetings and gives the fund a defensible, pre-stated rationale for each decision.
The second link is who casts the ballot. Broadly there are two models. Some funds vote in-house, with an internal stewardship team executing the policy directly. Others delegate voting to the external asset managers who run their portfolios, in which case the manager's house policy usually governs unless the fund instructs otherwise.
The third link is research and recommendations, supplied by proxy advisors — principally ISS and Glass Lewis. These firms analyse the ballot items and issue recommendations the fund can adopt, modify or ignore.
The fourth link is execution and disclosure: the votes are submitted through voting platforms, recorded, and (for many funds and their managers) disclosed publicly, including through SEC filings such as Form N-PX for the managers voting on a fund's behalf.
Do pension funds just follow the proxy advisors?
This is the most common misconception, and the evidence cuts against it. Institutional investors use proxy advisors heavily for research, but sole reliance is rare. Large funds run meaningful internal processes: CalPERS, for instance, has an internal team that conducts its own research into companies the fund owns, a process described as requiring hundreds of hours of work. The advisor supplies an input; the fund makes the decision.
That distinction has become legally important. US scrutiny of proxy advisors intensified sharply, with a 2026 executive order — framed around "protecting American investors from foreign-owned and politically motivated proxy advisors" — pushing investors to do more of their own analysis rather than leaning on advisor recommendations. Separately, legislation aimed at proxy-advisory firms advanced. The combined effect is that delegating your judgment wholesale to an advisor is now both reputationally and legally riskier, reinforcing the case for funds to vote from their own guidelines.
The insight: voting power and money management have been quietly decoupling
The most important development in how pension funds vote is structural. For years, the default was that whoever managed the money also voted the shares — so the giant index managers accumulated enormous voting power as a byproduct of running passive mandates. Pension funds are now decoupling the two.
Through split-voting and pass-through voting arrangements, a fund can keep its assets with an external manager while voting those shares according to its own policy rather than the manager's house position. The driver is accountability: when public voting records (via Form N-PX) revealed that some large managers were voting in ways that diverged from their clients' stewardship commitments, funds with strong guidelines responded by reclaiming the ballot. The principle emerging is that ownership rights should follow the asset owner, not the agent that happens to hold the asset.
For a universal owner, this is the heart of the matter. If you own a slice of the entire market, your votes are one of the few tools you have to manage system-wide risks. Letting an intermediary cast those votes by default means outsourcing your most direct lever of influence — which is exactly why the most sophisticated owners are taking it back.
How a fund keeps its votes consistent with its values
The mechanism that holds the whole chain together is the voting policy, and its quality is what separates funds that vote their values from funds that merely claim to. A detailed, well-maintained policy lets a fund instruct managers precisely, override advisor recommendations on principle, and explain every vote on financial-materiality grounds. A vague policy leaves the fund dependent on whoever is downstream — the manager's defaults or the advisor's house view.
This showed up clearly under political pressure: funds with strong, comprehensive voting guidelines largely maintained their positions on contested issues like climate-risk management, while funds with weaker guidelines were more likely to waver. The policy, not the press release, is what proved durable.
How to check how a pension fund voted
Transparency has improved enough that you can verify, not just trust. Funds publish their voting guidelines and, increasingly, their voting records — the New York State Common Retirement Fund, for example, makes its corporate-governance voting decisions public, noting that votes are made independently by the fund based on its own guidelines. Where a fund votes through external managers, those managers' votes can be cross-checked through Form N-PX filings. Reading the guidelines tells you what a fund intends; reading the records (or the managers' N-PX) tells you what it actually did.
What it means for asset owners
The practical takeaways are consistent for any institution thinking about its own voting. Build a detailed voting policy anchored in financial materiality, because it is both the engine of consistency and a shock absorber against political pressure. Do not outsource judgment wholesale to proxy advisors — use their research, but own the decision, which is now a regulatory expectation as much as a best practice. And recognise that voting power is separable from money management: if your votes matter to you, structure your manager relationships so those votes are cast according to your policy, through split-voting or pass-through arrangements, rather than defaulting to the agent. For an owner of the whole market, the ballot is too important to leave on autopilot.
