Who the money went to
Grants this organization reported paying: Schedule I Part II of the Form 990, or the grants-paid list on the 990-PF. Open a year for every recipient. Recipients link to their own page when the grant names an EIN we have (990-PF grants list no EIN, so those link only on an exact, unique name and state). Grants to individuals are counted; their names are not shown.
2024 · 1 grant to organizations · $3.1M
Listed grants add up to $3,100,000; the return's “grants paid” expense line says $3,396,880. Returns can differ here (grants paid vs. accrued, items listed elsewhere); check the filing.
2023 · 1 grant to organizations · $2.6M
Listed grants add up to $2,600,000; the return's “grants paid” expense line says $2,878,345. Returns can differ here (grants paid vs. accrued, items listed elsewhere); check the filing.
Negative amounts are returned or refunded grants; they are listed last and left out of the totals of grants paid.
Who gave
Contributor names are not public for this form type.
Public charities filing Form 990 or 990-EZ report large donors on Schedule B, but the IRS withholds their names and addresses from public copies. Private foundations (990-PF) are different: their contributors are public.
Finances
Newest first. Each filing: its name on one row, its figures on the row beneath. Greyed filings are superseded by a later return for the same period and are left out everywhere else on this page.

Where the money went
Every expense line on each return, biggest first: Form 990 Part IX (with its program, management and fundraising columns), 990-EZ Part I, or 990-PF Part I. Event marks lines the organization itself describes as events. “Events” in each summary adds those lines, conferences and meetings, and the direct costs of fundraising events. Unusual is not the same as improper. Many of these patterns have ordinary explanations. Check the filing.
