About this record
From the SEC's insider-transaction filings (Forms 3, 4 and 5). Every reporting director and officer carries a Commission-assigned identifier (CIK), so these footprints are identifier-verified - no name matching involved. Insiders file when they transact, so dates are filing dates: "last filed" never means "served until". This layer is not yet joined to the nonprofit register - identity joins ship only after independent review.
