Breakdown13F · Form 4

Institutions 108.43%Insiders 1.11%

A 13F quarter can total more than the shares outstanding — sub-advisers file the same block twice, and a filer's own share count can be a quarter stale. No split is drawn from it.

Shares outstanding 153.46M · Float 121.91M · 79.4% free float

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.
