Union Bank of California Successfully Implements Acorn Systems Performance Analyzer Solution to Replace Their Legacy Costing System

Performance Analyzer's flexibility and scalability were critical, Acorn's ability to partner and expertise key as well

Houston, TX – June 23, 2008 — Acorn Systems is pleased to announce that Union Bank of California, N.A. , the primary subsidiary of UnionBanCal Corporation (NYSE:UB), has successfully implemented Acorn Systems Performance Analyzer platform to replace their legacy costing system and is on its way to further enhance its uses of Acorn capability. Union Bank selected Acorn over other alternatives because Acorn's software is flexible and scalable enough to handle its requirements, and Acorn's world-class consulting team provided the financial service and performance management expertise the bank needed.

Acorn Systems' flexibility allowed Union Bank to use its proven costing methodology, while taking advantage of Acorn's ability to scale and deliver additional benefits: greater structure, discipline and security; decrease of the risk as a stand-alone application with manual interfaces to other financial reporting systems; improved reconciliation and trace back; and a platform capable of handling Union Bank's ongoing needs including integration to other aspects of performance management.

Grace Lou, Senior Vice President of Product Costing and Analysis states, "Acorn has been a true partner with us, helping us improve and automate our costing system. The enhanced system provides a strong foundation for us to better respond to the bank's strategic goals in cost containment. Acorn's experienced team listened to us, thought out of the box, and worked with us to deliver exactly what we needed. We selected them not just for the software capability, but their ability to truly listen and understand our needs and be a partner in delivering costing excellence."

Jerome Patterson, Senior Vice President of Acorn Systems, adds "Union Bank of California had an extremely sophisticated costing methodology, yet the platform had significant limitations in terms of maintenance, sustainability, and ability to keep up with the strategy and execution of the bank. The joint team worked collaboratively to ensure we retained all that was working, while migrating to Acorn's platform which unlocks significant potential for enhanced value. We look forward to continued collaboration with Union Bank of California as it pursues its cost containment and operational efficiency objectives."
