Every figure on this page is that foundation's own latest filed year, which is 2022 or later. This foundation is listed because its Form 990-PF says it does not restrict giving to preselected organizations and it paid at least 5 grants totaling $100K or more that year. Latest-year grants and terms per foundation from IRS 990-PF e-file returns; the newest tax year is partial until the IRS finishes releasing it. Grants are de-duplicated on funder, year, recipient and amount, so identical repeat grants collapse into one and totals can run low. Full method.
