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.
