A dramatic new chapter was opened in the more and more complicated history of BlackBerry Limited. The plan of acquisition by Canadian financial holding company Fairfax Financial failed, an alternative agreement was started that still involves Fairfax together with other companies and it a change of CEO was decided.

About two weeks ago, the news came that a consortium led by the Canadian financial company Fairfax Financial had offered $4.7 billion to buy BlackBerry Limited. The smartphone maker only signed a letter of intent that allows the company to deal with other possible buyers and there are rumors of other potential offers. However, the news came of a lawsuit filed by a shareholder that could further complicate the situation.

A consortium led by the Canadian financial holding company Fairfax Financial has offered $4.7 billion to buy BlackBerry Limited, the producer of the famous mobile phones. The company has signed a letter of intent with this consortium, so the contract is not yet closed but it’s its intention to proceed with the sale.

A few hours ago it was announced that Microsoft will acquire the Nokia Devices & Services division, which is the one that manages the mobile business, for 3.79 billion Euros. The Redmond company will also pay 1.65 billion Euros for the license to use a number of Nokia patents for a total of 5.44 billion Euros (about $7.2 billion or £4.6 billion) which will be paid in cash.
