Unity Bank Selects ACI Worldwide for Anti Money Laundering Compliance(Watford, England. – 2 May 2007) – ACI Worldwide (NASDAQ: TSAI), a leading international provider of enterprise payment solutions, today announced that Unity Bank Plc, a leading West African bank based in Abuja, Nigeria, has selected ACI Proactive Risk ManagerTM software to automate its procedures in order to comply with the national Money Laundering Prohibition Act of 2004. Unity Bank is the third major bank in Nigeria to license this technology from ACI. Access Bank plc and Zenith Bank plc have also licensed Proactive Risk Manager.

Unity Bank selected ACI to supply its Proactive Risk Manager system for Anti-Money Laundering, as the software is able to detect suspicious activity quickly, render threshold reports to the Nigerian Financial Intelligence Unit (NFIU) in an acceptable format, and effectively use neural networks, rules-based strategies and workflow management software.   The solution is modular in design, so it can be expanded to include monitoring for issuer fraud and managing risk across the enterprise, with an account-based view of transactions.   

Lamis Shehu Dikko, executive director risk management & control of Unity Bank Plc, said, “It is vitally important that we protect our solid reputation as a financial partner in the niche markets we serve.  The selection process to find a partner that has the experience of implementing a world-class solution to meet our stringent objectives was exhaustive.  We were impressed with ACI’s outstanding track record as a strategic technology partner to the world’s leading financial institutions for the last 30 years.  The Proactive Risk Manager solution offers a cost-effective and rapid deployment to meet the reporting requirements of the NFIU.  In addition, ACI has multiple users of this technology in our country, which will enhance the overall level of support.”  

Steve Wright, president of ACI Worldwide EMEA, said, “We now have three major Nigerian Banks that have invested in our ACI Proactive Risk Manager technology.  This is a strong vote of confidence in ACI and our commitment to this important market.  We welcome Unity Bank as a customer and look forward to a long and mutually satisfying relationship as a payment technology partner to this highly innovative and progressive bank.”
