"Technology plays a vital role in today's financial services competitive landscape," said Garth Sheane, CEO, Coastal Community Credit Union. "This new banking system will allow our employees to respond to the increasingly complex needs of members and to manage correspondingly complex products and services.

The Canadian version of The Complete Credit Union Solution localized the core banking product for the overall Canadian market with a particular focus in three areas: retirement accounts; loan and mortgage processing; and regulatory requirements. This localized functionality enhances a proven platform that was built around a powerful Oracle(R) relational database. It offers credit unions of all membership sizes the technology tools to succeed in a highly competitive financial services marketplace.

In addition to The Complete Credit Union Solution, the credit union will implement Open Solutions' cView (CRM/business intelligence) and Channel Management Center (CMC) for universal translation between core, business and delivery systems, as well as other software modules.

Open Solutions Chairman and CEO Louis Hernandez, Jr. said, "We are very excited to see early adoption of our localized product by a Canadian credit union that clearly sees the benefits of migrating to Open Solutions' open architecture. Our solutions have been helping U.S.-based banks and credit unions achieve their strategic business objectives for the last 10 years. With the introduction of the Canadian version of The Complete Credit Union Solution in November 2005, Canadian credit unions now have the opportunity to meet both their strategic goals and their member service goals."
