Municipal Credit Union to Deliver Documents Electronically with Software from ACI Worldwide

OMAHA, Neb.--

MCU Selects ACI's e-Courier to Power E-Mail

Delivery of Statements to Members

ACI Worldwide (Nasdaq:TSAI), a leading international provider of enterprise e-payment solutions, today announced that New York-based Municipal Credit Union, one of the oldest and largest credit unions in the United States, has licensed ACI's e-Courier(TM) software to launch an electronic document delivery channel for its members.

MCU will initially use e-Courier to send personalized statements to members via e-mail -- the electronic delivery channel consumers overwhelmingly prefer. In a multiphase project, MCU plans to add alerts, PIN mailers, customer service advices and investment service information, and to broaden the output channels and formats to include Quicken and MS Money attachments, as well as wireless and voice integration. Municipal Credit Union is also using the powerful archiving capabilities of e-Courier to make e-statements available to all of its member services representatives.

"Our licensing of e-Courier will help us open an entirely new communication channel for our members," said Barry Grant, chief information officer, Municipal Credit Union. "Through the ease and convenience of e-mail, our members can choose to receive statements electronically. In turn, we can hold down costs by eliminating the expenses associated with printing and postal delivery."

To enroll in the e-mail statement service, members will surf to MCU's Web site and elect to receive statements electronically. The enrollment process will provide an explanation of the service and features and lead members through the activation process. After three months of receiving both paper and electronic statements, MCU will stop sending paper statements unless the member specifically requests paper.

ACI's e-Courier employs industry-standard encryption and digital signature capabilities to ensure that documents are authentic and private. E-mails may include content-rich information, interactive links to information on new products and links to services at MCU's Web site. ACI's unique tracking and archival capabilities give MCU the ability to accurately track the status of each message, including up-to-date details of when it was submitted, relayed, delivered, viewed and acted upon.

ACI has extended e-Courier's statement repository feature for MCU to give its customer service representatives the ability to quickly access an online image of a customer's statement in exactly the same format as it is viewed by the customer. This will reduce customer service talk time and improve responsiveness by allowing both the customer and the customer service representative to look at the same copy of a statement. It also reduces administrative time by eliminating the need to search other archives, and reduces cost by eliminating paper archives.

"With e-Courier, MCU can leverage its existing Internet site to connect with its members," said Don McCormick, managing director of ACI's e-Courier business unit. "And when MCU is ready, e-Courier offers the flexibility to expand its e-mail offerings to alerts and other types of communication -- basically any document MCU sends to its members via paper and post now can be securely delivered via e-mail with e-Courier."

In addition to e-Courier, MCU uses ACI's industry-leading BASE24(R) e-payment processing application. MCU joins other financial institutions that have licensed ACI's e-Courier for electronic delivery of financial documents, including First National Bank of Omaha, Commerce Bank & Trust and Central Technology Services.

What are people saying about mortgages today:

Rates on 30-year mortgages edged down last week to a seven-month low. Mortgage-giant Freddie Mac reported Thursday that 30-year, fixed-rate mortgages fell to 6.3 percent, down slightly from 6.31 percent two weeks ago. It put rates at the lowest level since they were at 6.24 percent the first week of March.

Bank of Hawaii, Central Pacific Bank, Territorial Savings Bank and Wells Fargo Home Mortgages all cut their 30-year mortgage rates to 5.75 percent this week.

Most people think of a mortgage as a means to an end. After all, you buy a house, not a home loan. But a mortgage is much more than the path to homeownership. It is a financial instrument that must be managed, just like any other financial investment.
