Bloomberg News reports that Citigroup Inc. (NYSE: C) lost $5.11 billion in the first quarter. This was worse than analysts had expected and was its second straight quarterly loss on at least $15 billion of writedowns and increased loan losses as customers fell behind on home, car and credit-card payments. Specifically, Citigroup's loss of $1.02 per share is the opposite of its profit of $5 billion, or $1.01 per share, in the first three months of 2007. Analysts were expecting a loss of 95 cents per share.

But it looks like Citi is doing something about the problem. Bloomberg News reports that Citi plans to cut costs by as much as 20%. It cites a Financial Times story that quoted CEO Vikram Pandit as saying: "It is clearly feasible for Citigroup to take 10, 15, 20 percent off its cost base, especially in information technology and operations." The cuts would include job losses among Citi's 370,000 employees.

And although its revenue plunged 48% to $13.2 billion, Citi beat analysts' expectations of $11.1 billion. Investors seem to be cheering the news about the cost cuts and the lower than expected drop in revenues. Citi is up 8.8% in pre-market.
