The extra dividend is good news for the bank's parent company BNP Paribas of France that owns most of the shares. It will receive 2 billion euros. The bank claims the dividend is the result of "sound capital management".
The dividend still needs to be approved by a general meeting, but this seems a formality.
Last week BNP Paribas Fortis launched a restructuring plan that envisages 2,430 job losses by 2018, though the bank also intends to recruit new staff.
