Fair Isaac Expands ScoreNet Service to Deliver Greater Precision for Customer Management.

MINNEAPOLIS -- ScoreNet Subscribers Now Can Receive Monthly Score Updates, Accompanied by an Enhanced Set of Consumer Credit Attributes Generated from Experian Credit Files

Fair Isaac Corporation (NYSE:FIC), the leading provider of analytics and decision technology, today announced that its ScoreNet(R) Service has been expanded to offer subscribing banks and businesses their choice of up to 202 credit attributes from Experian consumer credit files, accompanying Fair Isaac scores calculated at Experian. Subscribers can also now conduct monthly score updates delivered over Fair Isaac's proprietary ScoreNet Service network.

Monthly credit score updates give lenders more up-to-date risk evaluations of their customers. Lenders use credit file attributes, which provide information from each credit file such as how many bankcards the person has, to gain a deeper understanding of their customers' credit status and history. By greatly expanding its suite of credit file attributes, ScoreNet Service is enabling subscribers to further refine their strategies for decreasing customer delinquencies, increasing balances and building stronger customer relationships.

"ScoreNet Service's richer set of credit attributes helps lenders to get even more mileage from Fair Isaac credit bureau scores," said Ron Totaro, vice president of Global Scoring Solutions for Fair Isaac. "Lenders can apply these attributes in many ways to improve their bottom line, such as by selecting attributes that will fine-tune their credit risk evaluation or improve their account retention strategies, or increase their cross-sell opportunities."

"Greater frequency of score updates can translate into sharper risk prediction and improved customer management strategies," said Barbara Dalmau, product management director of Global Scoring Solutions for Fair Isaac. "Now even small lenders can check their customers' payment status across all lenders every month, just as the largest credit card issuers do."

Mr. Totaro noted that subscribers who use ScoreNet Service for account management can get expert guidance directly from Fair Isaac consultants. "Our experts have the unique combination of deep knowledge of Fair Isaac scores and extensive experience working with credit bureau data. This enables them to select the right attributes to solve specific business problems such as modeling segment populations or refining account management decisions," he said.

For more than a decade, ScoreNet Service has provided businesses with a one-stop source for Fair Isaac credit bureau scores, including revenue, bankruptcy and FICO(R) risk scores from all three national credit reporting agencies. To help businesses segment their customers, the service can also deliver consumer credit attributes with each score, derived from the underlying credit bureau report. In addition to standard credit attributes such as "worst public record" and "number of trade lines on file," businesses tapping Experian credit files now can choose from a wide variety of additional attributes such as "time of most recent delinquency," "aggregate monthly payment for open trades," and "highest utilization" of specific types of financial services products.
