The four-line truth

Lines are separate lifecycle measures and are never summed: committed = donor-published award/approved-commitment flows or signed recipient-confirmed commitments within the displayed source coverage period, including exact named commitments, plus reviewed current forward-portfolio aggregates that are never accumulated across source snapshots; awaiting = latest-FY statutory 'approved for future payment' or audited future-support-obligation balance; deployed = disclosed paid amounts, split into statutory, recipient-confirmed, and donor-reported evidence; in vehicles = transfers to controlled vehicles, DAFs, recipient foundations, or unresolved associated vehicles pending onward evidence (withheld-amount gifts counted separately). Absence of events is absence of loaded evidence, not zero giving.

Shares this person disclosed giving away, filed within two business days — the freshest evidence on this site, and years ahead of any tax return. Two limits are load-bearing: Form 4 does not name the donee, so these shares may have reached an independent charity or a foundation the family controls; and gift rows file at a price of zero, so values shown are estimates at the nearestquarter-end price implied by SEC Form 13F filings (a median across thousands of independent managers, public domain) — not the price on the gift date. They are therefore counted in none of the money lines above.

US private foundations must name material grantees on Form 990-PF, so recipient-level detail here is compelled, not volunteered.

Voluntary points reward disclosure the donor chose — publishing an open grants database, and naming recipients. Compelled points reflect how completely and how currently their statutory filings land. The split exists because disclosure regimes differ by jurisdiction: a high compelled score is law-abiding, not generous, and a low one may reflect a rule the donor did not write.
