Jeff & Current Directors would still be running the company, even if Brookfield got over 50% of the shares, at least until the next Annual Meeting, when they could vote in their own people, assuming they didn't get over 90%, which gives them the right of forcing holdouts to tender.
To get 90% so they could force everyone to tender, they will have to offer a premium that is high enough for Jeff and his close associates and family (who have over 10% among them, I hear) to cause them to sell. Any other people still independent shareholders at that time also will be the same deal to sell their shares.
Minority shareholders can be a pain in the neck to Brookfield and they don't seem to like Jeff very much. To get rid of him, they will have to pay using another "final final offer".
