There shares are already included in the outstanding shares. That's why it won't change. These shares were converted last year. So the current O/S already includes it.
Do you get it now?
There just selling their shares because they want out. That simple.
Only May 5/8 conversions added an additional 296 mil to the float. Because they were taken from preferred. So again O/S will not change.
Doesn't mean people can't dump shares they already have.
