Foundation governance guide

Endowment oversight and spending policy

Nonprofit Liaison Team5 min readLast reviewed 13 September 2026

Practitioner-written governance guidance

A community foundation board holds money meant to last forever, and has to decide every year how much of it to spend now. That decision lives inside a legal framework — UPMIFA, adopted in nearly every state — that asks the board to act prudently, balancing current grantmaking against the long-term purchasing power of the fund. The board's job is to set a defensible spending policy, oversee the investments that fund it, and document that both were done with care.

None of this requires the board to be investment professionals. It requires them to govern the process well: a clear policy, a competent committee, good information, and a record of prudent decisions.

Last reviewed 13 September 2026. General information, not legal or investment advice — UPMIFA and its application vary by state and by your governing documents. Confirm with qualified counsel and your investment advisors.

The legal frame: prudence under UPMIFA

Most states have adopted the Uniform Prudent Management of Institutional Funds Act (UPMIFA), which governs how charities manage and spend endowment funds. Two things about it matter for a board:

It sets a prudence standard, not a formula. UPMIFA asks the board to manage and invest endowment funds prudently, considering factors like the fund's purposes, general economic conditions, the possible effect of inflation, expected total return, and the organization's other resources.
It allows spending below the original gift value, prudently. UPMIFA replaced the old rule that barred spending an endowment below its "historic dollar value." A board may spend from a fund that has dipped below the original gift amount if it does so prudently under the statute's factors — but that judgment has to be made and documented, not assumed.

Your state's version may differ in details (a few states modified the uniform text), so confirm the specifics that apply to you.

Setting a spending policy

A spending policy translates prudence into a repeatable number. The most common approach is to spend a set percentage of a trailing average of the fund's market value — for example, a percentage applied to a multi-quarter or multi-year average — because averaging smooths out market swings so grant budgets don't lurch with the markets.

What the board is really balancing is intergenerational equity: spend too much and you erode the real value future generations receive; spend too little and you shortchange today's community. Setting and periodically revisiting the rate — and being able to explain the reasoning — is the board's call, usually on the investment committee's recommendation.

Handling underwater funds

When a specific endowed fund's value falls below the original gift amount, it's described as underwater. UPMIFA generally permits continued prudent spending from underwater funds, but this is exactly where boards should slow down: apply the prudence factors deliberately, weigh donor intent, watch the accounting and disclosure implications, and document the decision fund by fund. A blanket "we always spend X%" applied without this thought is the kind of thing that looks careless in hindsight.

The investment policy statement

The board's investment oversight runs through an investment policy statement (IPS) — the document that sets objectives, risk tolerance, asset allocation ranges, the role of any outside managers or an outsourced CIO, and how performance is monitored. The investment committee owns the detailed work under a clear charter; the full board approves the policy and holds ultimate responsibility. Review the IPS on a set schedule, not only after a bad quarter.

Document the prudence

The thread through all of this is documentation. UPMIFA's standard is about the process the board followed, so the board's protection is a clear record: the spending policy and the reasoning behind it, the IPS and its reviews, the investment committee's minutes, the analysis behind underwater-fund decisions, and the conflict-of-interest disclosures of anyone connected to a manager or vendor. Keeping those together — rather than split across board books, custodian reports and email — is what lets a foundation show, later, that it stewarded the endowment prudently.

Frequently asked questions

What is UPMIFA in simple terms? A state law, adopted in nearly every state, that tells charities how to prudently manage and spend endowment funds. It sets a prudence standard and factors to weigh, and it allows spending a fund below its original gift value if the board does so prudently.

Can a foundation spend from an endowment that's lost value? Generally yes under UPMIFA — spending from an "underwater" fund is permitted if done prudently under the statute's factors, with attention to donor intent and disclosure. Confirm your state's rules and get advice; document the decision.

What's a typical endowment spending rate? Many foundations spend a set percentage of a trailing average of market value, often in the range of about 4–5%, though the right rate depends on the foundation's goals, its donors, and market conditions. It's a board decision, not a fixed rule.

Does the board need to be investment experts? No. The board governs the process — approving the investment policy, overseeing the investment committee and any advisors, and setting the spending policy — rather than picking securities.
