Fair Isaac Announces Version 2.2 of Model Builder for Faster Development and Deployment of Decision Systems.

MINNEAPOLIS -- New Release Empowers Financial Institutions to Respond to Market and Strategy Changes While Improving Compliance with Corporate and Regulatory Priorities

Fair Isaac Corporation (NYSE:FIC), the leading provider of analytics and decision technology, today announced the introduction of Model Builder 2.2, the latest release of its enterprise decision management tool specifically designed to streamline and build more powerful analytic models. Model Builder 2.2 improves the speed and accuracy of developing high-performing models that can be custom-configured to meet the specific business requirements of financial institutions across lines of business and applications.

Model Builder is part of Fair Isaac's software and solutions for enterprise decision management, which combines data analytics, modeling and policy-level control to allow companies to define and manage their automated business systems for improved efficiency and greater profitability. A unique feature of Model Builder 2.2 that is of significant value to global financial services companies is the ability to develop accurate models using less data while maintaining compliance with necessary corporate governance policies and regulations, such as Basel II.

"Model Builder includes a number of important technical and business benefits that provide users the ability to quickly develop powerful analytic models with little transaction data," said Todd Davis, vice president of enterprise decision management at Fair Isaac. "This is extremely important for global financial services companies who compete in emerging geographic and market segments, as well as companies entering new markets who will benefit from the expanded reach of Fair Isaac's Enterprise Decision Manager platform."

Credit risk officers, credit managers and risk management analysts also will benefit from improved programming capabilities provided by Model Builder 2.2. Application Programming Interfaces (API) provide advanced analytic users with the ability to work in the Java programming language, while novice users are able to take full advantage of the intuitive interface for developing and deploying predictive analytics. While Model Builder is already known for helping to meet the explicit detail and documentation requirements of regulators, Model Builder 2.2 adds a new level of report generation capabilities to aid in documenting and governing the analytic process.

The bootstrap validation capabilities provided by Model Builder 2.2 allow organizations to build precision models while requiring less data. Model Builder 2.2 also improves the speed of transactional data preparation by equipping companies with the addition of the Fair Isaac Data Cleanser and Variable Processor. Fair Isaac's Data Cleanser removes the unnecessary and valueless data and provides options for the handling of missing and special values. Variable Processor allows users to easily summarize transaction information to the customer level.

Fair Isaac's Enterprise Decision Manager(TM) software integrates Model Builder with complementary Fair Isaac decision management tools -- such as Fair Isaac Blaze Advisor for rules management and Decision Optimizer for improved decisions -- that have been successfully used by more than 250 organizations.

Fair Isaac offers clients project management, implementation assistance, data analysis and model preparation in support of their use of Model Builder. Leveraging a company's existing technology investments in data warehousing and business application systems, Enterprise Decision Manager is available on a number of platforms ranging from Windows laptops to IBM Mainframes, while also available on all the leading J2EE application servers as well as Linux and .Net environments. Because the software is database-independent, businesses also can leverage their Oracle, DB2 and SQL Server-based data stores.
