Foundation data: grants paid, latest complete year 2023 (2024 partial — included, each grant labelled by fiscal year). Each grant below shows its fiscal year plainly. 990-PF grant rows carry no recipient EIN — the recipient name shown is the organisation GetFunded matched the row to; matches can be wrong, so check the filing object ID against the source filing.

Grants paid by fiscal year
From the foundation-years file. "Not linked" grants are counted here and in the total above, but have no named recipient to list. "Basis" is which 990-PF line the grants-paid figure was read from — qualifying distributions or disbursements for charitable purposes; the two lines are not the same measure. Years after FY2024, where present, are totals only — the matched-grant files end at FY2024, so no named grants are shown for those years.
