U.S. customers of Cable and Wireless PLC will need to start looking for an alternative provider of corporate voice and data services after the financially-troubled U.K. network operator Wednesday announced sweeping restructuring changes, including a complete exodus from its loss-making North American business.

The restructuring plans coincided with C&W reporting a pre-tax net loss for the year of £6.4 billion ($10.1 billion as of March 31, the last day of the period being reported), compared to £4.5 billion the year before, the company said in a statement.

C&W also saw full-year revenue decline 24% to £4.4 million from £5.7 million the year before.

To improve its bottom line, C&W has decided to exit the U.S. market where it has been losing around $1 million per day, according to CEO Francesco Caio. "We want to exit quickly but sensibly," he said in a conference call with analysts and journalists

Company officials declined to provide details of how they plan to sever their contracts and service-level agreements (SLA) with U.S. customers, claiming that such information is sensitive to their negotiating position.

"We intend to maintain the contracts and SLAs we've got with these customers while we explore our options," the company said in a statement. "We will communicate openly with our customers about this."

How large U.S. Internet customers with international operations, such as Yahoo and eBay, will respond to the shutdown remains to be seen, said Sandra O'Boyle, an analyst at the Amsterdam, Netherlands, office of Current Analysis. "There are still enough service providers in the U.S., although the number of international providers is dwindling," she said. "C&W was never able to really challenge the big U.S. players, such as WorldCom and AT&T and was losing a lot of money in this market, but it's still sad to see another competitor disappear."

C&W has been on the retreat in the U.S. since September 2002, when the operator sold its U.S. retail voice and data business to Primus Telecommunications Group.

The new strategy also calls for a key focus on its domestic U.K. market where C&W, despite its relatively strong position, aims to improve its cost base by slashing 1,500 jobs over the next several months.

The goal, Caio said, is to "create a group of profitable national telecom companies with strong positions in their primary markets." By removing global and regional divisions, the group will have a simpler organizational structure that will ensure lower overheads, clear lines of accountability and a more effective transfer of knowledge and skills, he said.
