Endowment size and reporting scope

An endowment can contain many individual accounts with different donor purposes. Investing them together changes how assets are managed, while the accounts continue to record each beneficiary's interest. The market value of a pooled vehicle can also include reserves or other long-term funds. An endowment balance, a managed pool and total organizational assets can consequently differ even when all figures are reported accurately. Survey scope and definitions

The official USD 1,300.000 million figure and the FY2025 survey's USD 1,089.519 million describe their respective dates and reporting categories. The official balance retains its stated label, endowment, reported as nearly this rounded amount. A change in currency, period or included accounts can produce a different total; the figures are presented separately. Official financial scope

Source: NACUBO · Data through FY2026

The FY2025 survey value for Miami University is USD 1,089.519 million, compared with USD 813.323 million for FY2024. The USD 276.196 million movement is 33.96% of the earlier balance. It includes changes in investments as well as additions and distributions. NACUBO explicitly distinguishes this change in market value from an investment rate of return. FY2025 respondent values and definitions

The available history begins in FY2016 at USD 446.795 million and ends in FY2025 at USD 1,089.519 million. The change across those observations is USD 642.724 million. The smallest reported balance in the displayed series is USD 446.795 million in FY2016; the largest is USD 1,089.519 million in FY2025. These are closing asset values. They do not show how much of a year's movement came from new gifts, spending or investment results. NACUBO historical workbook

Investment returns

Performance report

A trailing multi-year return is an annualized compound result over the period shown. The one-year figure covers the final year. These periods overlap, so their returns are not added. A published dollar investment gain can reflect accounting categories and cash flows that differ from the percentage performance calculation. Return definitions and reporting basis

Spending policy and payout

Miami reports $32.8 million of endowment support during FY2026, a $5.3 million increase from FY2025. The earlier $27.5 million amount in the chart is calculated as the reported current-year support less the stated increase. It is labelled as that arithmetic comparison. Spending disclosure

Distribution report

A policy percentage and a budget-support percentage use different denominators. The first applies to the policy's asset base; the second compares endowment support with the institution's revenue or expenditure. Gifts for a specific scholarship or program also limit how its distribution can be used. Pooled investment management does not turn restricted support into money available for any operating purpose. Spending measures

Governance and investment office

Miami's president's report separates campaign fundraising, cash gifts, commitments and endowment support. The Investment and Treasury Services office publishes additional financial information. The survey history follows the combined respondent scope rather than the university's separate non-endowment pool. Investment governance

Federal excise tax on investment income

Public Law 119-21 changed Section 4968 for tax years beginning after December 31, 2025. Applicable private institutions must have at least 3,000 tuition-paying students in the preceding tax year, with more than half located in the United States, and student-adjusted endowment of at least $500,000. The rates are 1.4% from $500,000 through $750,000 per student, 4% above $750,000 through $2 million, and 8% above $2 million. Enacted law, Section 70415 These rates apply to net investment income, using the law's prior-year asset and student-count definitions.

Section 4968 excludes state colleges and universities described in Section 511(a)(2)(B). Supporting foundations retain their own legal and filing identities, with related-organization rules read alongside the public-university exclusion. A foundation's public endowment value does not, by itself, assign it a private-college tax tier.

FY2025 size-band comparison

The FY2025 survey value of USD 1,089.519 million places this respondent in the $1B to $5B band. The published band contains 125 respondents and USD 268.0 billion of aggregate assets. Its average five-year annualized net return is 10.8%, and its ten-year average is 8.0%. The size classification follows the survey-year balance even where an official disclosure on this page uses a later year or a different portfolio scope. NCSE size groups NCSE average net returns

The peer mix describes average reported exposures within one size band. It does not reveal individual securities or the availability of cash at a particular institution. Respondents can also use different policy benchmarks. NCSE returns are net of external management fees and expenses for periods ending June 30, 2025; those periods and fee labels govern any numerical return comparison on this page.

Public records and reporting dates

NACUBO's respondent is Miami University. Annual financial statements and any nonprofit return can cover a different legal entity or a wider group of resources. A university, a supporting foundation and an investment pool can each report its own assets. Total organizational assets also include resources outside the endowment, and the tax-return accounting period can differ from the survey's reporting year. Those distinctions govern how public records are compared. Respondent identity
