CSC NAMED NORTH AMERICAN INSURANCE BPO MARKET LEADER BY CELENT COMMUNICATIONS

Industry Analyst Firm Ranks CSC as Top Business Process Outsourcing Provider to All Tiers of Insurers

EL SEGUNDO, Calif., Sept. 22, 2004 – Computer Sciences Corporation (NYSE: CSC) announced today that it has been named the “clear leader in providing business process outsourcing (BPO) services to North American insurance carriers” by financial services technology research and advisory firm Celent Communications.

In its Aug. 31 report entitled “Insurance BPO Market Survey: Will The Watched Pot Ever Boil?” Celent collected data on approximately 300 BPO contracts – two thirds of which are based in North America – currently providing core insurance services. According to the report, CSC was the top provider to Tier 1, 2 and 3 North American insurance carriers based on number of BPO contracts. CSC was also named one of the top providers, both in terms of estimated BPO revenue and full-time insurance BPO employees, and the leader in seven of eight process categories: policy administration, general systems, call center, billing, underwriting, support functions and distribution.

“As one of the world's largest IT services providers, CSC combines significant outsourcing capabilities with insurance expertise and comprehensive insurance application software,” said Craig Weber, senior analyst in Celent’s insurance practice and author of the report. “Their strength as a BPO provider is not surprising.”

“Celent's recognition of CSC's BPO market leadership is gratifying,” said Jim Cook, president of CSC’s Financial Services Group. “Through outsourcing, CSC’s clients gain speed-to-market and financial flexibility to better execute their unique strategies.”

Celent estimates that total core insurance BPO, excluding processes such as human resources, benefits and payroll, will total more than $2.5 billion in 2004, growing to almost $3 billion by 2006. Celent suggests that virtually all insurance carriers can benefit from assessing their operations for possible BPO opportunities.
