Fairfax Financial Holdings Limited has issued a proposal to Blackberry for a $4.7 billion buyout, or $9 per share. Fairfax already owns 10% of Blackberry. Blackberry is currently trading at $8.20 so the offer seems fair to say the least. Even though BlackBerry's board has agreed with the terms of the of the letter of intent, no deal has officially gone through yet. The companies will now move into what is knows as a "diligence period" where all the terms and conditions of both parties must be met first before the deal is official.
