Just a few weeks after announcing it was buying New York's First Data Corp. in a $22 billion all-stock deal, Brookfield-based financial technology giant Fiserv Inc. said it has signed the largest, centralized and online real-time account processing client in the company's history – New York Community Bancorp Inc., the parent company of Westbury, N.Y.-based New York Community Bank.

New York Community, with $51.2 billion in assets, is the largest regional bank based in New York by assets.
