MMA INSURANCE EXPANDS SERVICE AGREEMENT WITH CSC AND CONVERSANT DATA TO IDENTIFY FRAUDULENT HOUSEHOLD CLAIMS

Aldershot, 9 August 2005 – Computer Sciences Corporation (NYSE: CSC), a leading global information technology (IT) services company, and Conversant Data Limited, a leading UK anti-fraud services provider, announced today that MMA Insurance Plc (MMA) has expanded its agreement with the two companies to use Advances, a service-based anti-fraud solution offering, to analyse household insurance claims. The expanded agreement is a result of milestones achieved since MMA began using Advances to screen its motor claims for fraud.

Advances combines Conversant Data’s claims fraud detection and prevention expertise with CSC’s Fraud Evaluator, a comprehensive software tool used for early detection of potential claims fraud, to deliver in-depth analysis and scoring of claims data.

MMA was the first UK insurer to use Advances since its launch in September 2004. By identifying suspicious claims with the service, MMA has seen an increase in the number of claims declined because they are fraudulent and reduced fraud investigation costs.

“Advances is an integral part of MMA’s anti-fraud strategy,” said Bob Still, MMA’s Customer Services Director. “In just six months, Advances is delivering real business benefits in motor claims fraud reduction. Extending the use of Advances to analyse our household claims data, is the next logical step and we’re confident that we will see the same return on investment.”

“We are delighted that this service is already providing MMA with significant business results,” said John Maitz, vice president and head of CSC’s General Insurance division for Europe, the Middle East and Africa. “Advances is real proof that insurers can combat fraud in a cost-effective and timely manner. We look forward to applying our extensive experience to help MMA achieve similar results for its household claims business.”
