6 listediTime on the board is observed from the annual filings: the IRS files no appointment date, so the bar counts years from the first filing the person appears on - a lower bound, not a filed start date. Names are exactly as filed. The IRS publishes no person identifier, so this edition does not yet link a person across organisations in the tables. The network map shows same-name matches as likely links only, never as confirmed.Tenure and departures are observed across annual filings. Observed tenure is a lower bound - a member may have joined before the first year on record.
