Every figure is read directly from IRS Form 990 / 990-PF e-file XML — this organization’s own return for FY2021 (financials across 2017–2021), and the filings of 5funders that report grants to it. “On record” means captured in the filings we have parsed — a funder that does not e-file, or whose grant detail is not itemized, will not appear. Filings run roughly 12–24 months behind. view filing
