Management does not believe there are any such matters that will have a material effect on the consolidated financial statements that are not currently accrued for. However, in light of the uncertainties inherent in these matters, it is possible that the ultimate resolution may have a material adverse effect on Customers’ results of operations for a particular period, and future changes in circumstances or additional information could result in accruals or resolution in excess of established accruals, which could adversely affect Customers’ results of operations, potentially materially.</span></div><div style="margin-top:9pt;text-align:justify"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:700;line-height:120%">United States Department of Education Matter</span></div><div style="margin-top:9pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">In third quarter 2018, Customers received a Final Program Review Determination ("FPRD") letter dated September 5, 2018 from the ED regarding a focused program review of Higher One's/Customers Bank's administration, as a third party servicer, of the programs authorized pursuant to Title IV of the Higher Education Act of 1965. The ED 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 ED’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 disagreed with the FPRD and appealed the asserted financial liabilities of $6.5 million, and a request for review has been submitted to trigger an administrative process before the ED’s Office of Hearing and Appeals.</span></div><div style="margin-top:9pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">On March 26, 2020, the ED and Customers filed a Joint Motion to Dismiss with Prejudice (the "Joint Motion") with the United States Department of Education. The Joint Motion states that the ED and Customers reached an agreement that resolves the liabilities at issue in the appeal. The Joint Motion was granted on April 27, 2020. As part of the settlement, the liabilities assessed in the FPRD were reduced to $3.0 million (the "settlement amount"). Customers had previously recorded a liability in the amount of $1.0 million during third quarter 2019 and increased its liability by an additional $1.0 million in first quarter 2020. The remaining $1.0 million is expected to be funded from funds in an escrow account set-up at the time of Customers' acquisition of the Disbursement business from Higher One in 2016.</span></div><div style="margin-top:9pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:700;line-height:120%">Specialty’s Café Bakery, Inc. Matter</span></div><div style="margin-top:9pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:115%">On May 27, 2020, the appointed Chapter 7 Trustee for Specialty’s Café Bakery, Inc. (“Debtor”) filed a voluntary petition for relief under Chapter 7 of the Bankruptcy Code in the United Stated Bankruptcy Court for the Central District of California. On October 28, 2020, the Trustee, as plaintiff, filed her amended adversary complaint (“Adversary Complaint”) against Customers Bank and the SBA seeking to avoid and recover for the benefit of the Debtor’s estate and its creditors the payment made by the Debtor to Customers Bank in the amount of $8.1 million in satisfaction of a Payroll Protection Program loan made by Customers Bank to the Debtor (the “PPP Loan Payment”). The Trustee seeks to avoid and recover the entire PPP Loan Payment from the Bank under the authority provided in 11 U.S.C. §547 and §550, which together permit a trustee of a bankruptcy debtor to avoid and recover, for a more equitable distribution among all creditors, certain transfers made within ninety (90) days before the filing of the bankruptcy petition. The Bank intends to vigorously defend itself against the Trustee’s Adversary Complaint and is currently unable to reasonably determine the likelihood of loss nor estimate a possible range of loss.</span></div>
