Appropriated resources also retain any donor restrictions when moved from the investment pool to a spending account. Spending measures

The long-term investment pool holds foundation-managed endowments alongside other funds. Individual agreements govern beneficiary purposes and amendments. 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

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.

Section 4968 uses statutory asset and student definitions, including related-organization rules.

NCSE's allocation categories combine strategies with different liquidity and valuation practices. Its Alternatives group can include private capital, hedge funds and real assets. Matching that broad weight would not establish identical holdings. The displayed mix is a survey average, not this institution's target allocation. Published category weights are shown with an explicit rounding difference so the full bar totals 100%. NCSE allocation definitions
