Sydney, March 17 2006 - Cognos (NASDAQ: COGN; TSX: CSN), the world leader in business intelligence and corporate performance management, today announced that Corrs Chambers Westgarth is standardising its Australia-wide financial reporting system on the Cognos 8 Business Intelligence (BI) and Planning platforms.

Corrs Chambers Westgarth (Corrs) is one of Australia's leading law firms and provides a comprehensive range of legal services to businesses throughout Australia and overseas. It has approximately 920 partners and staff with offices in Sydney, Melbourne, Brisbane, Gold Coast, Perth and Canberra. Corrs' national finance team is responsible for the firm's financial management and works closely with approximately 120 partners to carry out accounting, financial analysis, strategic analysis and reporting requirements.

Corrs required an integrated financial planning solution to simplify and more efficiently manage all aspects of financial reporting and business intelligence.

Corrs chose Cognos 8 BI and planning solution due to Cognos' significant implementation base. It also selected Cognos for its ability to integrate with its other systems.

Cognos 8 delivers the most comprehensive set of BI capabilities available on a single, web-based services-oriented architecture (SOA).

It provides decision makers at all enterprise levels with a consistent, accurate view of information to better manage performance. Customers can add product components to the suite as needed, enabling them to grow BI organically with the changing needs of the business.

"Our implementation of Cognos 8 Business Intelligence as an enterprise-wide financial reporting standard will benefit the entire Corrs organisation. Cognos will enable us to improve the firm's financial reporting by replacing labour intensive processes with powerful business modelling tools and a central reporting repository that allows timely access to information," said Colman Kenna, Manager Financial Information Systems at Corrs Chambers Westgarth.

The Cognos 8 BI and planning solution will be progressively implemented over the next 18 months.
