In connection with the settlements, the Bank became subject to a Consent Order, Order to Pay Restitution, and Order to Pay Civil Money Penalty dated May 13, 2014 issued by the FDIC (“the FDIC Consent Order”) and a DOJ Consent Order (“the DOJ Consent Order”), which was approved by the U.S. District Court for the District of Delaware on September 29, 2014.
