London, UK, September 27, 2004

CGI, one of the world's leading IT and business process services providers, today announced that it has completed the implementation of its insurance administration system, GIOS (global insurance open solution) at Ireland's top health insurer, Vhi Healthcare.

GIOS is a highly flexible component based solution, which covers all aspects of administration for all forms of insurance product. It provides Vhi Healthcare with one single customer data source, which enables the insurer to offer outstanding service to its 1.6 million customers and cuts administration time as information need only be entered once. By automating the insurance administration processes, GIOS is set to bring considerable efficiency savings to Vhi Healthcare.

Vincent Sheridan, chief executive at Vhi Healthcare, said: "GIOS is easily customised and highly scalable, which is vital to us moving forward as we further grow our business. With GIOS we are now able to bring new products to market much more quickly, whilst also improving the quality of service to our customers."

Gavin Chapman, managing director for CGI Northern Europe said: "CGI has worked in joint partnership with Vhi Healthcare throughout the implementation to ensure GIOS is tailored to meet their specific business needs and we are delighted that the system is now fully supporting Vhi Healthcare's business. With implementations in more than 30 countries across the globe supporting all lines of business and multiple languages and currencies, GIOS is probably the most flexible and functional solution for insurance administration on the market today."
