Officers, directors and trustees as filed, with the year of the return they appeared on.
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.
