American Express Co. is handing off management of its corporate network to Hewlett-Packard Co.'s EDS unit.

EDS, of Plano, Tex., announced the five-year deal Monday, though the contract was signed in December and the technology outsourcing provider has already completed the initial stage of the transition.

EDS said it is managing the New York financial company's desktop computing network and its global voice and data networks, and will also provide on-site technical support services in more than 130 countries.

Matthew Robinson, Amex's chief technology officer, said in an HP press release that the agreement will help his company enhance innovation and customer service "while continuing to decrease operating costs."

HP, of Santa Clara, Calif., acquired EDS in August of last year for $14 billion.
