Carreker Corporation Press Release - April 16, 2002

Metavante, the financial technology subsidiary of Marshall & Ilsley Corporation (NYSE: MI), is a leading provider of outsourced processing services for banks. Carreker’s FraudLink Deposit helps banks identify potentially fraudulent deposit transactions. It is one of a broad suite of Carreker risk management solutions used by 18 of the largest 20 banks in North America, and 70 of the next 100, as well as financial institutions in the United Kingdom and Australia. These institutions typically realize payback on FraudLink within three to nine months.

According to Tom Vleisides, Carreker’s senior vice president, Alliance Management, “Once again, we are expanding our relationship with Metavante to bring another proven solution to community and regional banks. Metavante’s business model lowers the entrance cost of such a system, spreading it out as a monthly service fee. They already provide ReserveLink™, our reserve reduction solution and our FraudLink On-Us solution, which detects fraudulent checks which are drawn on a bank customer’s account.”

Jamie Geschke, senior vice president and general manager, Metavante Financial Technology Services, points out that for most community banks, fraud losses have become a growing expense burden. A 2000 survey of check fraud conducted by the American Bankers Association (ABA) found that commercial banks experienced almost a half million fraud cases and that financial losses from fraud were suffered by 69 percent of banks, including 67 percent of community banks, which was an increase from 49 percent in 1998. In October 2001, the ABA endorsed Carreker fraud prevention products for its members.

“As larger financial institutions continue to increase their protection against check fraud losses through advanced technology like Carreker’s suite, fraud perpetrators are instead targeting smaller banks that have not implemented a fraud detection defense system,” Geschke said. “Now, institutions of any size have an economically feasible solution to combat check fraud.”

Carreker’s full line of risk management solutions includes several check fraud detection products under the FraudLink name including FraudLink On-Us, Deposit, Kite, and Positive Pay. FraudLink Positive Pay, which offers real-time fraud detection for Positive Pay items presented at the branch, will be enhanced with the incorporation of the Payee Name Verification (PNV) module which validates the payee name on corporate checks, adding another level of validation and risk prevention for Positive Pay clients. Carreker recently introduced Carreker’s On-line Risk Expert (FraudLink CORE), which aggregates data from Carreker’s risk products along with data from a bank’s existing fraud systems to a single workstation and prioritizes and scores suspects for effective fraud decisioning.
