Earlier this week BlackBerry announced that they were calling an end to their pursuit for a buyer. They did however receive a $1 billion investment from Fairfax Financial and unnamed institutional investors, who were finally revealed today in an SEC filing

According to the filing, Fairfax has contributed $250 million to the deal as the other partners of Mackenzie Financial Corp., Brookfield Asset Management Inc., Markel Financial, Canso Investment Counsel Ltd. and Qatar Holding LLC fill in the remaining $750 million. 

Fairfax Financial had originally planned a deal to buy BlackBerry that was worth $4.7 billion, and while BlackBerry was rumored to have other offers on the table, they ended their strategic review period and are no longer actively seeking a buyer.
