Insiders — filings are in the shares behind the receipt.
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.
This listing is a depositary receipt and the Form 4 positions here are filed in the shares behind it, a different unit from the share count and in a ratio the filings never state, so no insider percentage is shown.
