MINNEAPOLIS, MN, Oct. 24, 2005 -- Fair Isaac Corporation (NYSE:FIC) today announced it has been positioned by Gartner, Inc. in the Leaders Quadrant of the 2005 Magic Quadrant(1) for Basel II Risk Management Application Software report. According to Gartner, vendors listed in the "Leaders" quadrant have a proven track record in Basel II vision and business investment, which indicates they are well-positioned for the future. Leaders do not necessarily offer the best products for every customer project, but they do provide solutions that offer relatively lower failure risk. Leaders in this market have paired advanced technology with broad offerings or have specific, rich functionality.

In addition to delivering advanced analytic and decision management applications for customer management, risk management and fraud control to the world's major financial institutions, Fair Isaac is a leading innovator in risk management solutions for retail and small business lending. The company has closely tracked the development of Basel II and other regulatory trends and is collaborating with clients in affected industries to address required changes before new guidelines take effect.

"We believe being positioned in the Leaders Quadrant of the growing Basel II solutions market by Gartner is confirmation of our ability to help lending institutions implement advanced risk management operations that help them comply with new regulations and meet aggressive portfolio growth and profitability goals," said Andrew Jennings, vice president and general manager, Global Customer Management, Fair Isaac. "Effective compliance solutions integrate data, analytics, strategies, business rules, processes and technology in a continuous cycle of learning and improvement. As a worldwide risk management leader, Fair Isaac is uniquely positioned to assist lenders in turning Basel II compliance into opportunity."

The Basel II Capital Accord (Basel II), developed to enhance the stability of global financial systems, redefines the methodology institutions use for calculating capital reserves, making these calculations more sensitive to risk. Companies that most effectively monitor, scrutinize and mitigate portfolio credit, operational and market risk will receive the greatest rewards. Gartner defines a Basel II solution as an integrated risk management platform that enables the collection, preparation, management, calculation and reporting of risk elements by a financial services provider during the course of its current and anticipated operations.(2)

The implementation of best practice risk management including credit scoring, segmentation and decision automation techniques can play a critical role in achieving competitive advantages in capital calculations and requirements. Companies working with Fair Isaac for Basel II compliance are implementing scoring and segmentation through solutions like Fair Isaac's FICO(R) scores and TRIAD(TM) adaptive control system.

Businesses also can tap the advanced fraud detection and business rules management capabilities of Fair Isaac's Falcon One(TM) system and Fair Isaac Blaze Advisor, which are already in wide use by companies in financial services and other industries. Falcon One system is a new enterprise fraud software solution for effectively combating both existing and emerging types of fraud at every customer interaction. Blaze Advisor allows customers to easily add and update regulatory rules in new or existing systems, while integrating these rules with risk or other models in production.
