Each figure comes from the foundation's latest filed year, 2022 or later. This foundation is listed because its Form 990-PF says giving is not restricted to preselected organizations and it paid at least 5 grants totaling $100K or more that year. Grants and application terms come from each foundation's latest IRS 990-PF e-file return. 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 count once and totals can run low. Full method.
