The DOE program review covered the award years beginning in 2013 through the FPRD issuance date, including the time period when Higher One was acting as the third party servicer prior to Customers' acquisition of the Disbursement business on June 15, 2016. The FPRD determined that, with respect to students enrolled at specified partner institutions, Higher One/Customers did not provide convenient fee-free access to ATMs or bank branch offices in such locations as required by the DOE’s cash management regulations. Those regulations, which were in effect during the period covered by the program review and were revised during that period, seek, among other purposes, to ensure that students can make fee-free cash withdrawals. The FPRD determined that students incurred prohibited costs in accessing Title IV credit balance funds, and the FPRD classifies those costs as financial liabilities of Customers. The FPRD also requires Customers to take prospective action to increase ATM access for students at certain of its partner institutions. Customers disagrees with the FPRD and has elected to appeal the FPRD, including the asserted financial liabilities of $6.5 million, and a request for review has been submitted to trigger an administrative process before the DOE’s Office of Hearing and Appeals. Customers intends to vigorously defend itself against the financial liabilities established in the FPRD through that administrative appeals process and it further intends to pursue resolution of the FPRD’s prospective action requirements during the appeals resolution process. Based on preliminary discussions with the DOE and further analysis performed by Customers and certain partner institutions, Customers has estimated the range of possible loss to be $1.0 million to $3.0 million as of September 30, 2019. </span></div><div style="margin-top:9pt;"><span style="background-color:rgb(255,255,255, 0.0);color:#000000;font-family:'Times New Roman';font-size:10pt;font-weight:400;line-height:120%;">Customers established a legal reserve in the amount of $1.0 million during third quarter 2019, as no amount within the range is more likely than any other amount in the range. </span></div><div><span><br/></span></div><div><span style="background-color:rgb(255,255,255, 0.0);color:#000000;font-family:'Times New Roman';font-size:10pt;font-weight:700;line-height:120%;">Bureau of the Fiscal Service Notice of Direct Debit (U.S. Treasury Check Reclamation)</span></div><div style="margin-top:9pt;"><span style="background-color:rgb(255,255,255, 0.0);color:#000000;font-family:'Times New Roman';font-size:10pt;font-weight:400;line-height:120%;">On June 21, 2019, Customers received a Notice of Direct Debit (U.S. Treasury Check Reclamation) from the Bureau of the Fiscal Service (“Reclamation Notice”).
