Insiders — filings are in another share unit.
A Form 4 total here can count shares the filer formally disclaims — an award voted by proxy, for instance — which the holder's own Schedule 13D/G excludes, so where the two disagree the schedule's smaller figure is used.
The Form 4 positions here total more than the shares outstanding, so the filings and the share count are not on the same basis — usually an unlisted unit behind the listed one — and no insider percentage is shown.
