Customers that entrusted a former unit of Fiserv Inc. with custody of their retirement plans are suing the technology company to recoup money lost in the Bernard Madoff fraud.
The lawsuit, filed in U.S. District Court in Denver, seeks to recover up to $1 billion on behalf of 800 investors.
A former unit of Fiserv Inc. that custodied retirement-plan money for Madoff’s firm had received repeated warnings from one of its financial advisors in regards to the Ponzi scheme Madoff was orchestrating.
