Prem has five Canadian companies holding about 16.9% voting power.
FFHL Group appears to be his too, and it has 14.8% voting power.
Then FairFax (US) Inc has 10.5% voting power.
And several of the smaller "investment" companies are also owned by FairFax... has anyone sat down and really figured out how much of BlackBerry that Prem controls at this point?
