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:12pt;text-align:justify"><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:120%">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 States Bankruptcy Court for the Central District of California. On October 28, 2020, the Trustee, as plaintiff, filed her amended adversary complaint (“Adversary Complaint”) against the 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 the Bank in the amount of $8.1 million in satisfaction of a PPP loan made by the Bank to the Debtor (the “PPP Loan Payment”). The Trustee sought 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. On December 2, 2021, the Bank filed a motion for summary judgement, arguing that the Trustee had failed to establish the elements under 11 U.S.C. §547 necessary to recover the PPP Loan Payment and other affirmative defenses to any such recovery. On February 2, 2022, the United States Bankruptcy Court for the Central District of California granted the Bank’s motion for summary judgment, finding that the PPP Loan Payment was not recoverable by the Trustee. The Trustee has elected not to appeal this decision and, on February 23, 2022, the case against the Bank was closed by the United States Bankruptcy Court for the Central District of California.</span></div>
