The DOJ Consent Order was approved by the U.S. District Court for the District of Delaware on September 29, 2014. Under the DOJ Consent Order, Navient is solely responsible for reimbursing SCRA benefits and related compensation on behalf of both its subsidiary, Navient Solutions, Inc., and the Bank.

This includes implementing new SCRA policies, procedures and training, updated billing statement disclosures, steps to ensure its third-party service providers are also fully compliant in these regards, and overseeing Navient’s restitution responsibilities. Notwithstanding the assumption by the Consumer Financial Protection Bureau (the “CFPB”) of the role of the Bank’s primary consumer compliance regulator in January 2015, the FDIC will continue to monitor the Bank’s improved compliance management system, policies and procedures until it is satisfied the Bank has demonstrated its ability to sustain the enhancements and additions implemented in response to the FDIC Consent Order. Pursuant to the terms of the DOJ Consent Order, the Bank will remain subject to certain DOJ reporting and record-keeping requirements until September 29, 2018. In May 2014, the Bank received a Civil Investigative Demand (“CID”) from the CFPB as part of the CFPB’s separate investigation relating to customer complaints, fees and charges assessed in connection with the servicing of student loans and related collection practices of pre-Spin-Off SLM Corporation (“pre-Spin-Off SLM”) by entities now subsidiaries of Navient during a time period prior to the Spin-Off. Two state attorneys general have provided the Bank identical CIDs and others have become involved in the inquiry over time. To the extent requested, we have been cooperating fully with the CFPB and the attorneys general but are not in a position at this time to predict the duration or outcome of the investigation.
