Associated Banc-Corp. of Green Bay, Wis., has implemented core processing software from Fiserv Inc.

The banking technology vendor said last week that Associated is using Fiserv CBS, which its CBS Worldwide unit offers to large banking companies worldwide.

The $22 billion-asset bank holding company is also using document management, online banking, data warehousing, and loan servicing software from the Brookfield, Wis., vendor.

Mark Quinlan, Associated's chief information officer and an executive vice president, said in a Fiserv press release that his company chose the CBS software because of its comprehensive capabilities, the vendor's reputation, and "the flexibility to easily customize the system. With the ability to make enhancements quickly, the CBS core solution will allow us to be nimble and more responsive to market changes and the needs of the business."
