Citigroup Inc., reeling from a record fourth-quarter loss, reorganized its flagging consumer division as Chief Executive Officer Vikram Pandit tries to reverse a profit slide at the bank's biggest revenue generator.

Steven Freiberg, who co-headed the unit, now will run U.S. and international credit cards, which accounted for 62 percent of total consumer revenue last year, the New York-based company said today in a statement. The rest of the group, mainly bank branches and non-bank lending, will be led in the U.S. by Terri Dial, hired today from Lloyds TSB Group Plc, and four regional chiefs outside the U.S. Citigroup has 8,500 consumer branches and 186 million credit-card accounts worldwide.
