Breakdown13F · Form 4
Shares outstanding 1.06M · Float —
Float — provider float is below the insider stake.
Insiders — filings are in another share unit.
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.
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.
The provider's float is smaller than the insider stake it should exclude, so it is not shown.
