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 · 63 grants to organizations · $504K
2023 · 48 grants to organizations · $312K
2022 · 57 grants to organizations · $293K
2021 · 0 grants to organizations · $0 · 1 summary line · $436K
This return lists 1 summary line (program totals pointing to a separate statement) instead of each grant. The itemized list was filed as an attachment that isn't in the IRS's public e-file data, so the recipients can't be shown.
2020 · 0 grants to organizations · $0 · 1 summary line · $23K
This return lists 1 summary line (program totals pointing to a separate statement) instead of each grant. The itemized list was filed as an attachment that isn't in the IRS's public e-file data, so the recipients can't be shown.
2019 · 0 grants to organizations · $0 · 1 summary line · $44K
This return lists 1 summary line (program totals pointing to a separate statement) instead of each grant. The itemized list was filed as an attachment that isn't in the IRS's public e-file data, so the recipients can't be shown.
Negative amounts are returned or refunded grants; they are listed last and left out of the totals of grants paid.
Who gave
Contributors listed on Schedule B of the Form 990-PF: name, city and state as filed (street addresses are not shown), with total and noncash contributions for the year. A link to an organization's page is tagged Fuzzy with its name-similarity score (0 to 1) when it rests on name and state; Schedule B lists no EIN, so no link here is an exact identifier match.
