Each figure is one return, as filed. A grantee's grants out are not shown to be the money it received: money is interchangeable, and two organizations' tax years can cover different months, so a grant received in one organization's 2023 can sit beside grants made in the other's 2023 without being the same dollars. Only grants over $5,000 are itemized, and private foundations' returns (990-PF) are not read here.
