Commitments and Contingencies Disclosure [Abstract]
Commitments, Contingencies and Guarantees	Commitments, Contingencies and Guarantees Commitments When we approve a Private Education Loan at the beginning of an academic year, that approval may cover the borrowing for the entire academic year. As such, we do not always disburse the full amount of the loan at the time of such approval, but instead have a commitment to fund a portion of the loan at a later date (usually at the start of the second semester or subsequent trimesters). At September 30, 2017, we had $1.9 billion of outstanding contractual loan commitments which we expect to fund during the remainder of the 2017/2018 academic year. At September 30, 2017, we had a $1.6 million reserve recorded in “Other Liabilities” to cover expected losses that we conclude are probable to occur during the one year loss emergence period on these unfunded commitments. Regulatory Matters On May 13, 2014, the Bank reached settlements with (a) the FDIC regarding disclosures and assessments of certain late fees, as well as compliance with the Servicemembers’ Civil Relief Act (“SCRA”) and (b) the Department of Justice (the “DOJ”) regarding compliance with the SCRA. 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. Under the terms of the Separation and Distribution Agreement, Navient is responsible for funding all liabilities under the regulatory orders and, as of the date hereof, has funded all liabilities other than fines directly levied against the Bank in connection with these matters which the Bank is required to pay. On March 27, 2017, the Bank received confirmation from the FDIC that effective March 23, 2017, the FDIC terminated the FDIC Consent Order. The termination was issued with no conditions. The Bank continues to be in full compliance with the DOJ Consent Order, including policy and procedure updates. 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 Consumer Financial Protection Bureau (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 by entities now subsidiaries of Navient during a time period prior to the Spin-Off (the “CFPB Investigation”). Two state attorneys general also provided the Bank identical CIDs and other state attorneys general have become involved in the inquiry over time (collectively, the “Multi-State Investigation”). To the extent requested, the Bank has been cooperating fully with the CFPB and the attorneys general conducting the Multi-State Investigation. Given the timeframe covered by the CIDs, the CFPB Investigation and the Multi-State Investigation, and the focus on practices and procedures previously conducted by Navient and its servicing subsidiaries prior to the Spin-Off, Navient is leading the response to these investigations. Consequently, we have no basis from which to estimate either the duration or ultimate outcome of these investigations. Additional lawsuits may arise from the Multi-State Investigation which may or may not name the Company, the Bank or any of their current subsidiaries as parties to these suits. As with the Illinois lawsuit described below, the Bank is not responsible for any of the alleged conduct in the Multi-State Investigation or any claims that may arise from related lawsuits. As contemplated by the Separation and Distribution Agreement relating to, and the structure of, the Spin-Off, Navient is legally responsible for, and has accepted responsibility to indemnify the Company against, all costs, expenses, losses and remediation that may arise from these matters. With regard to the CFPB Investigation, we note that on January 18, 2017, the CFPB filed a complaint in federal court in Pennsylvania against Navient, along with its subsidiaries, Navient Solutions, Inc. and Pioneer Credit Recovery, Inc. The complaint alleges these Navient entities, among other things, engaged in deceptive practices with respect to their historic servicing and debt collection practices. Neither SLM, the Bank, nor any of their current subsidiaries are named in, or otherwise a party to, the lawsuit and are not alleged to have engaged in any wrongdoing. The CFPB’s complaint asserts Navient’s assumption of these liabilities pursuant to the Separation and Distribution Agreement. On January 18, 2017, the Illinois Attorney General filed a separate lawsuit in Illinois state court against Navient - its subsidiaries Navient Solutions, Inc., Pioneer Credit Recovery, Inc., and General Revenue Corporation - and the Bank arising out of the Multi-State Investigation. On March 20, 2017, the Bank moved to dismiss the Illinois Attorney General action as to the Bank, arguing, among other things, the complaint failed to allege with sufficient particularity or specificity how the Bank was responsible for any of the alleged conduct, most of which predated the Bank’s existence. Following argument on the Bank’s motion on July 18, 2017, the Illinois court took the Bank’s motion under advisement. As of the date of this report, the court has not ruled on the Bank’s motion. As contemplated by the Separation and Distribution Agreement relating to, and the structure of, the Spin-Off, Navient is legally responsible for, has assumed, and has accepted responsibility to indemnify the Company against, all costs, expenses, losses and remediation that may arise from these matters. To date, two other state attorneys general (Washington and Pennsylvania) have filed suits against Navient and one or more of its current subsidiaries arising out of matters arising from the Multi-State Investigation. Neither SLM, the Bank, nor any of their current subsidiaries are named in, or otherwise a party to, the Washington or Pennsylvania lawsuits, and no claims are asserted against them. Each complaint asserts in its own fashion that Navient assumed responsibility for these matters under the Separation and Distribution Agreement for the alleged conduct in the complaints. Contingencies In the ordinary course of business, we and our subsidiaries are routinely defendants in or parties to pending and threatened legal actions and proceedings, including actions brought on behalf of various classes of claimants. These actions and proceedings may be based on alleged violations of consumer protection, securities, employment and other laws. In certain of these actions and proceedings, claims for substantial monetary damage may be asserted against us and our subsidiaries. It is common for the Company, our subsidiaries and affiliates to receive information and document requests and investigative demands from state attorneys general, legislative committees, and administrative agencies. These requests may be for informational or regulatory purposes and may relate to our business practices, the industries in which we operate, or other companies with whom we conduct business. Our practice has been and continues to be to cooperate with these bodies and be responsive to any such requests. We are required to establish reserves for litigation and regulatory matters where those matters present loss contingencies that are both probable and estimable. When loss contingencies are not both probable and estimable, we do not establish reserves. Based on current knowledge, management does not believe there are loss contingencies, if any, arising from pending investigations, litigation or regulatory matters for which reserves should be established.
