Union Bank, part of Japan's Mitsubishi UFJ Financial Group Inc , agreed to pay $35 million to settle the first class-action lawsuit arising from nationwide litigation accusing lenders of charging excessive overdraft fees.

The litigation consolidates lawsuits filed against more than two dozen U.S., Canadian and European lenders such as JPMorgan Chase & Co , Citigroup Inc and Wells Fargo & Co .

It accuses lenders of routinely processing transactions from largest to smallest rather than in chronological order. This can cause account balances to fall more quickly, and overdraft fees, typically $25 or $35, to pile up faster.

A notice of the Union Bank settlement was filed on Wednesday with the U.S. District Court in Miami. The settlement requires approval by U.S. District Judge James Lawrence King, who oversees the litigation.

King granted class certification in the Union Bank case in July. That meant that customers, estimated in the tens of thousands, could sue the San Francisco-based bank as a group.
