Breakdown13F · Form 4
Shares outstanding 53.70M · Float —
Float — provider float is below the insider stake.
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 provider's float is smaller than the insider stake it should exclude, so it is not shown.
