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.

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.
