Voting is not disposition. Each reporting person's cover page splits its holding into VOTING power (sole / shared) and DISPOSITIVE power (sole / shared). Voting and dispositive totals are summed WITHIN a person only — never across persons, because a group's members report overlapping interests in the same shares and the filing's aggregate is not their sum. Where a person's voting total is below its reported aggregate, the difference is shares it reports beneficial ownership of with no voting power reported; it is shown as a gap, never as a second position.

Percent is as filed. Percent is the filing's own percent of class, as filed (0–100). It's the reporting group's figure — not summed across filers, not recomputed against shares outstanding, not rescaled. Share counts are as filed and never subtracted across filings (a split would make that meaningless); the only change we show is the change in the as-filed percent against the prior captured filing.

We never call an amendment “new”. A filing is 'first captured' when we hold nothing earlier for that company + filer. On an amendment that means the original predates our window, not that the position is new — so we never badge an amendment 'new,' even when the raw data says so.

Escalations. An escalation is a filer moving from a passive 13G to an active 13D on the same company — telling the SEC it may now seek to influence control. It's a lower bound: a 13G filed before our window began is invisible and never guessed. If the 13D leg is a 13D/A, an earlier 13D predates our window, so the crossing shown is the first one visible inside it, not necessarily the filer's first.

Parsed Schedule 13D/G XML (events.db schedule_13dg + schedule_13dg_persons). 13D = active intent; 13G filers report passively under Rule 13d-1(b) QII / (c) Passive / (d) Exempt and are never activists. Percents are the reporting group's own as-filed figures and are NOT additive across filers — two filers can report the same shares. Structured 13D/13G coverage starts December 2024 (SEC XML mandate).
