American Express ( AXP)announced on Jan. 19 that it will shift 3,500 positions around the world and lay off 550 workers. The credit card company expects a pre-tax charge in its fourth quarter of $113 million, or 6 cents a share, as a result of the restructuring. As part of the overhaul, American Express will shutter its Greensboro, N.C., facility, shifting operations to locations across the U.S. The company is also looking at transferring work conducted in Madrid to facilities in Brighton, U.K., and Buenos Aires. Support for its Japan card business may also move from Sydney to Japan. "The company's decision reflects an overall decline in service volumes as more and more routine transactions have migrated to online and mobile channels," said American Express in a statement. "Staffing levels have declined to reflect those lower volumes, largely by not filling positions that opened up when employees leave. The reduced staffing levels have created significant vacancy levels in some facilities and, as a result, real-estate-related costs are inconsistent with anticipated needs." The moves are expected to be completed by the end of the year.
