Check the appropriate box below if the Form 8-K filing is intended to simultaneously satisfy the filing obligation of the registrant under any of the following provisions:

On August 19, 2015, Navient Solutions, Inc. (“NSI”), a wholly-owned subsidiary of Navient Corporation (the “Company,” “we” or “us”), received a letter from the CFPB notifying NSI that, in accordance with the CFPB’s discretionary Notice and Opportunity to Respond and Advise (“NORA”) process, the CFPB’s Office of Enforcement is considering recommending that the CFPB take legal action against NSI. The NORA letter relates to a previously disclosed investigation into NSI’s disclosures and assessment of late fees and other matters and states that, in connection with any action, the CFPB may seek restitution, civil monetary penalties and corrective action against NSI.

The purpose of a NORA Letter is to ensure that a party being investigated by the CFPB has the opportunity to present its positions to the CFPB before an enforcement action is recommended or commenced, in the form of a written statement setting forth any reasons of law or policy why the party believes the CFPB should not take legal action against it. NSI continues to believe that its acts and practices relating to student loans are lawful and meet industry standards and, where applicable, the statutory or contractual requirements of NSI’s other regulators. As such, NSI intends to make a NORA submission to the CFPB.

The Company is committed to resolving any potential concerns. However, it is currently unable to predict the timing or outcome of the NORA process. The Company cannot provide any assurance that the CFPB will not ultimately take legal action against NSI or that the outcome of any such action, if brought, will not have a material adverse effect on the Company. It is also not possible at this time to estimate a range of potential exposure, if any, for amounts that may be payable in connection with these matters and, as a result, reserves have not been established.

Statements that are not historical facts, including statements about the Company’s beliefs, opinions or expectations and statements that assume or are dependent upon future events, are forward-looking statements. Forward-looking statements are subject to risks, uncertainties, assumptions and other factors that may cause actual results to be materially different from those reflected in such forward-looking statements. These factors include, among others, the risks and uncertainties set forth in Item 1A “Risk Factors” and elsewhere in Navient’s Annual Report on Form 10-K for the year ended Dec. 31, 2014 and subsequent filings with the Securities and Exchange Commission; increases in financing costs; limits on liquidity; increases in costs associated with compliance with laws and regulations; changes in accounting standards and the impact of related changes in significant accounting estimates; any adverse outcomes in any significant litigation to which the Company is a party; credit risk associated with the Company’s exposure to third parties, including counterparties to the Company’s derivative transactions; risks inherent in the government contracting environment, including the possible loss of government contracts and potential civil and criminal penalties as a result of governmental investigations or audits; and changes in the terms of student loans and the educational credit marketplace (including changes resulting from new laws and the implementation of existing laws). The Company could also be affected by, among other things: changes in its funding costs and availability; reductions to its credit ratings or the credit ratings of the United States of America; failures of its operating systems or infrastructure, or those of third-party vendors; risks related to cybersecurity including the potential disruption of its systems or potential disclosure of confidential customer information; damage to its reputation; failures to successfully implement cost-cutting initiatives and adverse effects of such initiatives on its business; failures or delays in the planned conversion to our servicing platform of the recently acquired Wells Fargo portfolio of FFELP loans or any other FFELP or private education loan portfolio acquisitions; risks associated with restructuring initiatives; risk associated with the April 30, 2014 separation of Navient and SLM Corporation into two distinct, publicly traded companies, including failure to achieve the expected benefits of the separation; changes in the demand for educational financing or in financing preferences of lenders, educational institutions, students and their families; changes in law and regulations with respect to the student lending business and financial institutions generally; increased competition from other loan servicers; the creditworthiness of its customers; changes in the general interest rate environment, including the rate relationships among relevant money-market instruments and those of its earning assets versus its funding arrangements; changes in general economic conditions; the Company’s ability to successfully effectuate any acquisitions and other strategic initiatives; and changes in the demand for debt management services. The preparation of the Company’s consolidated financial statements also requires management to make certain estimates and assumptions including estimates and assumptions about future events. These estimates or assumptions may prove to be incorrect. All forward-looking statements contained in this report are qualified by these cautionary statements and are made only as of the date of this report. The Company does not undertake any obligation to update or revise these forward-looking statements to conform the statement to actual results or changes in its expectations.
