Citi, which has been restructuring to focus on more profitable businesses and promising markets, said net profit rose to $3.34 billion, or $1.02 per share, in the fourth quarter from $344 million, or 6 cents per share, a year earlier. Adjusted revenue rose 4.2 percent to $18.64 billion, but the increase came from gains on disposal of assets from Citi Holdings. Citi shares fell 2.5 percent in premarket trading on Friday.
