1. | SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
​ The Company Headquartered in Richmond, Virginia, Atlantic Union Bankshares Corporation (Nasdaq: AUB) is the holding company for Atlantic Union Bank. Atlantic Union Bank has 114 branches and approximately 130 ATMs located throughout Virginia, and in portions of Maryland and North Carolina as of September 30, 2022. Certain non-bank financial services affiliates of Atlantic Union Bank include: Atlantic Union Equipment Finance, Inc., which provides equipment financing; Atlantic Union Financial Consultants, LLC, which provides brokerage services; and Union Insurance Group, LLC, which offers various lines of insurance products. Effective June 30, 2022, the Company completed the sale of DHFB, which was formerly a subsidiary of the Bank. The unaudited consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. The unaudited consolidated financial statements have been prepared in accordance with U.S. GAAP for interim financial information and follow general practice within the banking industry. Accordingly, the unaudited consolidated financial statements do not include all the information and footnotes required by U.S. GAAP for complete financial statements; however, in the opinion of management all adjustments necessary for a fair presentation of the results of the interim periods presented have been made. The results of operations for the interim periods are not necessarily indicative of the results that may be expected for the full year or any other period. The unaudited consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and notes thereto included in the Company’s 2021 Form 10-K. Certain prior period amounts have been reclassified to conform to current period presentation. Adoption of New Accounting Standards In March 2020, the FASB issued Topic 848. This guidance provides temporary, optional guidance to ease the potential burden in accounting for reference rate reform associated with the LIBOR transition. LIBOR and other interbank offered rates are widely used benchmark or reference rates that have been used in the valuation of loans, derivatives, and other financial contracts. Topic 848 provides optional expedients and exceptions, subject to meeting certain criteria, for applying current GAAP to contract modifications and hedging relationships, for contracts that reference LIBOR or other reference rates expected to be discontinued. Topic 848 is intended to help stakeholders during the global market-wide reference rate transition period. The amendments are effective as of March 12, 2020 through December 31, 2022 and can be adopted at an instrument level. As of March 31, 2021, the Company utilized the expedient to assert probability of the hedged interest, regardless of any expected modification in terms related to reference rate reform for the newly executed cash flow hedges. The Company expects to incorporate other components of Topic 848 at a later date. This amendment does not have a material impact on the consolidated financial statements. Cash and Cash Equivalents For purposes of reporting cash flows, the Company defines cash and cash equivalents as cash, cash due from banks, interest-bearing deposits in other banks, short-term money market investments, other interest-bearing deposits, and federal funds sold. Restricted cash is disclosed in Note 7 “Commitments and Contingencies” in Part I, Item I of this Quarterly Report and is comprised of cash maintained at various correspondent banks as collateral for the Company’s derivative portfolio and is included in interest-bearing deposits in other banks in the Company’s Consolidated Balance Sheets. In addition, the Company is required to maintain reserve balances with the FRB based on the type and amount of deposits; however, on March 15, 2020 the Federal Reserve announced that reserve requirement ratios would be reduced to zero percent effective March 26, 2020 due to economic conditions, which eliminated the reserve requirement for all depository institutions. The reserve requirement is still at zero percent as of September 30, 2022. Accrued Interest Receivable The Company has elected to exclude accrued interest from the amortized cost basis in its determination of the ALLL, as well as the ACL reserve for securities. Accrued interest receivable totaled $48.1 million and $43.3 million on LHFI, $6.6 million and $7.0 million on HTM securities, and $13.3 million and $14.5 million on AFS securities at September 30, 2022 and December 31, 2021, respectively, and is included in “Other assets” on the Company’s Consolidated Balance Sheets. The Company’s policy is to write off accrued interest receivable through reversal of interest income when it becomes probable the Company will not be able to collect the accrued interest. For the quarters ended September 30, 2022 and September 30, 2021, accrued interest receivable write offs were not material to the Company’s consolidated financial statements. Segment Reporting Operating segments are components of a business where separate financial information is available and evaluated regularly by the CODMs in deciding how to allocate resources and in assessing performance. ASC Topic 280, S egment Reporting, requires information to be reported about a company’s operating segments using a “management approach,” meaning it is based on the way management organizes segments internally to make operating decisions and assess performance. Based on this guidance, historically, the Company has had only one reportable operating segment, the Bank. However, effective for the third quarter of 2022, the Company completed system conversions that allow its CODMs to evaluate the business, establish the overall business strategy, allocate resources, and assess business performance within two reportable operating segments: Wholesale Banking and Consumer Banking, with corporate support functions such as corporate treasury and others included in Corporate Other. The application and development of management reporting methodologies is a dynamic process subject to periodic enhancements. As these enhancements are made, financial results presented by each reportable segment may be periodically revised. Refer to Note 12 "Segment Reporting and Revenue" in Part I, Item I of this Quarterly Report for additional details on the Company’s reportable operating segments.
