SUMMARY OF SIGNIFICANT ACCOUNTI

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	12 Months Ended

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES The Company Effective October 1, 2021, Old Dominion Capital Management, Inc., and its subsidiary, Outfitter Advisors, Ltd., merged with and into DHFB, as part of an internal reorganization to streamline operations. Old Dominion Capital Management now operates as a division of DHFB. Effective March 1, 2021, Middleburg Financial, the Bank’s wealth management division was rebranded to Atlantic Union Bank Wealth Management, and Middleburg Investment Services, LLC changed its name to Atlantic Union Financial Consultants, LLC. Effective May 17, 2019, Union Bankshares Corporation changed its name to Atlantic Union Bankshares Corporation and Union Bank & Trust changed its name to Atlantic Union Bank. Basis of Financial Information The preparation of the consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from these estimates. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the ALLL, acquired loans, the valuation of goodwill, deferred tax assets and liabilities, and the fair value of financial instruments. Principles of Consolidation – The accompanying consolidated financial statements include financial information related to Atlantic Union Bankshares Corporation and its majority-owned subsidiaries and those variable interest entities where the Company is the primary beneficiary, if any. In preparing the consolidated financial statements, all significant inter-company accounts and transactions have been eliminated. Assets held in an agency or fiduciary capacity are not included in the consolidated financial statements. Accounting guidance states that if a business enterprise is the primary beneficiary of a variable interest entity, the assets, liabilities, and results of the activities of the variable interest entity should be included in the consolidated financial statements of the business enterprise. An entity is deemed to be the primary beneficiary of a variable interest entity if that entity has both the power to direct the activities that most significantly impact its economic performance; and the obligation to absorb losses or the right to receive benefits that could potentially be significant to the variable interest entity . Segment Reporting On May 30, 2019, the Bank notified TFSB that the Bank was terminating its primary agreement with TFSB and will no longer allow TFSB to offer residential mortgages from Bank locations. UMG operations remain discontinued, although the Company continues to offer residential mortgages through a division of the Bank. As of December 31, 2021 and 2020, the assets and liabilities, as well as the operating results, of the discontinued mortgage segment were not considered material. Management believes there are no material on-going obligations with respect to UMG’s business that have not been recorded or disclosed in the Company’s consolidated financial statements. Cash and Cash Equivalents - Restricted cash is disclosed in Note 10 “Commitments and Contingencies” 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 on 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. Investment Securities Available for Sale Held to Maturity - debt securities that the Company has the positive intent and ability to hold to maturity are classified as HTM. HTM securities are reported at carrying value. Transfers of debt securities into the HTM category from the AFS category are made at fair value at the date of transfer. The unrealized holding gain or loss at the date of transfer is retained in OCI and in the carrying value of the HTM securities. Such amounts are amortized over the remaining life of the security. Equity Investments significant influence are accounted for using the cost method of accounting. Under the cost method, investments are carried at cost and are adjusted only for other-than-temporary declines in fair value, certain distributions, and additional investments. Equity investments in unconsolidated entities with a readily determinable fair value that are not accounted for under the equity method will be measured at fair value through net income. Restricted Stock, at cost Interest income includes amortization of purchase premium or discount. Premiums and discounts on securities are generally amortized on the level-yield method without anticipating prepayments, except for MBS where prepayments are anticipated. Premiums on callable debt securities are amortized to their earliest call date. Discounts on callable debt securities are amortized to their maturity date. Gains and losses on sales are recorded on the trade date and determined using the specific identification method. The Company regularly evaluates AFS securities whose values have declined below amortized cost to assess whether the decline in fair value is the result of credit impairment. For AFS securities, the Company evaluates the fair value and credit quality of its AFS securities on at least a quarterly basis. In the event the fair value of a security falls below its amortized cost basis, the security will be evaluated to determine whether the decline in value was caused by changes in market interest rates or security credit quality. The primary indicators of credit quality for the Company’s AFS portfolio are security type and credit rating, which are influenced by a number of security-specific factors that may include obligor cash flow, geography, seniority, structure, credit enhancement and other factors. There is currently no ACL held against the Company’s AFS securities portfolio at December 31, 2021, consistent with December 31, 2020. See Note 3 “Securities,” for additional information on the Company’s ACL analysis. If unrealized losses are related to credit quality, the Company estimates the credit related loss by evaluating the present value of cash flows expected to be collected from the security with the amortized cost basis of the security. If the present value of cash flows expected to be collected is less than the amortized cost basis of the security and a credit loss exists, an ACL shall be recorded for the credit loss, limited by the amount that the fair value is less than amortized cost basis. Non-credit related declines in fair value are recognized in OCI, net of applicable taxes. Changes in the ACL are recorded as a provision for or reversal of credit loss expense. Charge-offs are recorded against the ACL when management believes the AFS security is no longer collectible. A debt security is placed on nonaccrual status at the time any principal or interest payments become 90 days delinquent. The Company evaluates the credit risk of its HTM securities on at least a quarterly basis. Management estimates expected credit losses on held-to-maturity debt securities based on an individual basis based on the PD/LGD methodology primarily using security-level credit ratings. Management has an immaterial ACL on HTM securities at December 31, 2021 and 2020. Loans Held for Sale Loans Held for Investment Loans that management has the intent and ability to hold for the foreseeable future or until maturity or pay-off generally are reported at their outstanding unpaid principal balances adjusted for any charge-offs, the ALLL, and any deferred fees and costs on originated loans. Interest income is accrued on the unpaid principal balance. Loan origination fees, net of certain direct origination costs, are deferred and recognized as an adjustment of the related loan yield using the interest method. Below is a summary of the current loan portfolios: Construction and Land Development Also, included in this category are loans generally made to residential home builders to support their lot and home construction inventory needs. Repayment relies upon the sale of the underlying residential real estate project. This type of lending carries a higher level of risk as compared to other commercial lending. This class of lending manages risks related to residential real estate market conditions, a functioning primary and secondary market in which to finance the sale of residential properties, and the borrower’s ability to manage inventory and run projects. The Company manages this risk by lending to experienced builders and developers by using specific underwriting policies and procedures for these types of loans and by avoiding excessive concentrations with any particular customer or geographic region. Commercial Real Estate – Owner Occupied Commercial Real Estate – Non-Owner Occupied Multifamily Real Estate Commercial & Industrial Residential 1-4 Family - Commercial Residential 1-4 Family - Consumer Residential 1-4 Family - Revolving Auto Consumer Other Commercial - portfolios carry risks associated with the creditworthiness of the borrower and changes in the economic environment. The Company manages these risks by using general underwriting policies and procedures for these types of loans and experienced underwriting. Loans that support small business lines of credit and agricultural lending are included in this category; however, neither are a material source of business for the Company. Nonaccruals, Past Dues, and Charge-offs The policy for placing commercial and consumer loans on nonaccrual status is generally when the loan is 90 days delinquent unless the credit is well secured and in process of collection. Consumer loans are typically charged-off when management judges the loan to be uncollectible but generally no later than 120 days past due for non-real estate secured loans and 180 days for real estate secured loans. Non-real estate secured consumer loans are generally not placed on nonaccrual status prior to charge off. Commercial loans are typically written down to net realizable value when it is determined that the Company will be unable to collect the principal amount in full and the amount is a confirmed loss. Loans in all classes of portfolios are considered past due or delinquent when a contractual payment has not been satisfied. Loans are placed on nonaccrual status or charged off at an earlier date if collection of principal and interest is considered doubtful and in accordance with regulatory requirements. In response to the COVID-19 pandemic, the Company offered short-term loan modifications to assist borrowers. The Company enhanced the monitoring over loans that received modifications, specifically full principal and interest payment deferrals, and considered nonaccrual treatment at which time the Company no longer expected to collect all principal and interest over the life of the loan. The process for charge-offs is discussed in detail within the “Allowance for Loan and Lease Losses” section of this Note 1. For both the commercial and consumer loan segments, all interest accrued but not collected for loans placed on nonaccrual status or charged-off is reversed against interest income and accrual of interest income is terminated. Payments and interest on these loans are accounted for using the cost-recovery method by applying all payments received as a reduction to the outstanding principal balance until qualifying for return to accrual. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured. The determination of future payments being reasonably assured varies depending on the circumstances present with the loan; however, the timely payment of contractual amounts owed for six consecutive months is a primary indicator. The authority to move loans into or out of accrual status is limited to senior Special Assets Officers and the Chief Credit Officer, though reclassification of certain loans may require approval of the Special Assets Loan Committee. Allowance for Loan and Lease Losses - valuation account that is deducted from the loans' amortized cost basis to present the net amount expected to be collected on the loans. Loans are charged off against the ALLL when management believes the loan balance is no longer collectible. Subsequent recoveries of previously charged off amounts are recorded as increases to the ALLL; however, expected recoveries do not exceed the aggregate of amounts previously charged-off. Management’s determination of the adequacy of the ALLL is based on an evaluation of the composition of the loan portfolio, the value and adequacy of collateral, current economic conditions, historical loan loss experience, reasonable and supportable forecasts, and other risk factors. The ALLL is estimated using a loan-level PD/LGD method for all loans with the exception of its overdraft, auto and third party consumer lending portfolios. For auto and third party consumer lending portfolios, the Company has elected to pool those loans based on similar risk characteristics to determine the ALLL using vintage and loss rate methods. The Company considers a number of economic variables in developing the ALLL of which the Virginia unemployment rate is the most significant. The ALLL quantitative estimate is sensitive to changes in the forecast of the Virginia unemployment rate over the two-year reasonable and supportable period, with the commercial portfolio being the most sensitive to fluctuations in unemployment. To forecast Virginia unemployment, the Company utilizes Moody’s economic forecasts. At December 31, 2021, the baseline scenario used in the two-year reasonable and supportable period forecast included the Virginia unemployment rate at an average of 2.6%, compared to an average of 5.0% Virginia unemployment rate in the baseline scenario forecast used for the December 31, 2020 estimate. Because current economic conditions and forecasts can change and future events are inherently difficult to predict, the anticipated amount of estimated credit losses on loans, and therefore the appropriateness of the ALLL, could change significantly. It is difficult to estimate how potential changes in any one economic factor or input might affect the overall allowance because a wide variety of factors and inputs are considered in estimating the allowance and changes in those factors and inputs considered may not occur at the same rate and may not be consistent across all loan types. Additionally, changes in factors and inputs may be directionally inconsistent, such that improvement in one factor may offset deterioration in others. While management uses available information to estimate expected losses on loans, future changes in the ALLL may be necessary based on changes in portfolio composition, portfolio credit quality, and/or economic conditions. Determining the Contractual Term Expected credit losses are estimated over the contractual term of the loans, adjusted for expected prepayments when appropriate. The contractual term excludes expected extensions, renewals, and modifications unless either of the following applies: management has a reasonable expectation at the reporting date that a TDR will be executed with an individual borrower or the extensions or renewal options are included in the original or modified contract at the reporting date and are not unconditionally legally cancelable by the Company. The Company’s ALLL measures the expected lifetime loss using pooled assumptions and loan-level details for financial assets that share common risk characteristics and evaluates an individual reserve in instances where the financial assets do not share the same risk characteristics. Collectively Assessed Reserve Consideration Loans that share common risk characteristics are considered collectively assessed. Loss estimates within the collectively assessed population are based on a combination of pooled assumptions and loan-level characteristics. Quantitative loss estimation models have been developed based largely on internal historical data at the loan and portfolio levels from 2005 through the current period and the economic conditions during the same time period. Expected losses for the Company’s collectively assessed loan segments are estimated using a number of quantitative methods including PD/LGD, Vintage, and Loss Rate. As part of its qualitative framework, the Company evaluates its current underwriting standards, geographic footprint, national and international current and forecasted economic conditions, expected government stimulus, and other factors to estimate the impact that changes in these factors may have on expected loan losses. The Company’s ALLL for the current period is based on a two-year reasonable and supportable forecast period with a straight-line reversion over the next two years to long-term average loss factors. Individually Assessed Reserve Consideration Loans that do not share risk characteristics are evaluated on an individual basis. The individual reserve component relates to loans that have shown substantial credit deterioration as measured by risk rating and/or delinquency status. In addition, the Company has elected the practical expedient that would include loans for individual assessment consideration if the repayment of the loan is expected substantially through the operation or sale of collateral because the borrower is experiencing financial difficulty. Where the source of repayment is the sale of collateral, the ALLL is based on the fair value of the underlying collateral, less selling costs, compared to the amortized cost basis of the loan. If the ALLL is based on the operation of the collateral, the reserve is calculated based on the fair value of the collateral calculated as the present value of expected cash flows from the operation of the collateral, compared to the amortized cost basis. If the Company determines that the value of a collateral dependent loan is less than the recorded investment in the loan, the Company charges off the deficiency if it is determined that such amount is deemed uncollectible. Typically, a loss is confirmed when the Company is moving toward foreclosure or final disposition. The Company obtains appraisals from a pre-approved list of independent, third party appraisers located in the market in which the collateral is located. The Company’s approved appraiser list is continuously maintained by the Company’s REVG to ensure the list only includes such appraisers that have the experience, reputation, character, and knowledge of the respective real estate market. At a minimum, it is ascertained that the appraiser is currently licensed in the state in which the property is located, experienced in the appraisal of properties similar to the property being appraised, has knowledge of current real estate market conditions and financing trends, and is reputable. The Company’s internal REVG, which reports to the Enterprise Risk Management group, performs either a technical or administrative review of all appraisals obtained in accordance with the Company’s Appraisal Policy. The Appraisal Policy mirrors the Federal regulations governing appraisals, specifically the Interagency Appraisal and Evaluation Guidelines and FIRREA. A technical review will ensure the overall quality of the appraisal, while an administrative review ensures that all of the required components of an appraisal are present. Independent appraisals or valuations are obtained on all individually assessed loans, as well as updated every twelve months for all individually assessed loans. Adjustments to real estate appraised values are only permitted to be made by the REVG. The individually assessed analysis is reviewed and approved by senior Credit Administration officers and the Special Assets Loan Committee. External valuation sources are the primary source to value collateral dependent loans; however, the Company may also utilize values obtained through other valuation sources. These alternative sources of value are used only if deemed to be more representative of value based on updated information regarding collateral resolution. The ALLL on loans individually assessed is updated, reviewed, and approved on a quarterly basis at or near the end of each reporting period. The Company performs regular credit reviews of the loan portfolio to review the credit quality and adherence to its underwriting standards. The credit reviews include annual commercial loan reviews performed by the Company’s commercial bankers in accordance with CLP, relationship reviews that accompany annual loan renewals, and independent reviews by its Loan Review Group. Upon origination, each commercial loan is assigned a risk rating ranging from one to nine, with loans closer to one having less risk. This risk rating scale is the Company’s primary credit quality indicator. Consumer loans are not risk rated unless past due status, bankruptcy, or other event results in the assignment of a Substandard or worse risk rating in accordance with the consumer loan policy. Governance The Company’s Allowance Committee, which reports to the Audit Committee and contains representatives from both the Company’s finance and risk teams, is responsible for approving the Company’s estimate of expected credit losses and resulting ALLL. The Allowance Committee considers the quantitative model results and qualitative factors when approving the final ALLL. The Company’s ALLL model is subject to the Company’s models risk management program which is overseen by the Model Risk Management Committee which reports to the Company’s Board Risk Committee. Acquired Loans – The Company has purchased loans, some of which have experienced more than insignificant credit deterioration since origination. Acquired loans are recorded at their fair value at acquisition date without carryover of the acquiree’s previously established ALLL, as credit discounts are included in the determination of fair value. The fair value of the loans is determined using market participant assumptions in estimating the amount and timing of both principal and interest cash flows expected to be collected on the loans and then applying a market-based discount rate to those cash flows. During evaluation upon acquisition, acquired loans are also classified as either or PCD or acquired performing. The acquired loans are subject to the Company’s ALLL Policy upon acquisition. Acquired performing loans are accounted for under ASC 310-20, Receivables – Nonrefundable Fees and Other Costs PCD loans reflect loans that have experienced more-than-insignificant credit deterioration since origination, as it is probable at acquisition that the Company will not be able to collect all contractually required payments. These PCD loans are accounted for under ASC 326 . The PCD loans are segregated into pools based on loan type and credit risk. Loan type is determined based on collateral type, purpose, and lien position. Credit risk characteristics include risk rating groups, nonaccrual status, and past due status. For valuation purposes, these pools are further disaggregated by maturity, pricing characteristics, and re-payment structure. ​ PCD loans are recorded at the amount paid. An ALLL is determined using the same methodology as other loans held for investment. The initial ALLL is determined on a collective basis and is allocated to individual loans. The sum of the loan's purchase price and ALLL becomes its initial amortized cost basis. The difference between the initial amortized cost basis and the par value of the loan is a noncredit discount or premium, which is amortized into interest income over the life of the loan. Subsequent changes to the ALLL are recorded through provision expense. ​ Troubled Debt Restructurings - The Company reviews previously restructured loans quarterly in order to determine whether any have performed, subsequent to the restructure, at a level that would allow for them to be removed from reportable TDR status. The Company generally would consider a change in this classification if the borrower is no longer experiencing financial difficulty, the loan is current or less than 30 days past due at the time the status change is being considered, and the loan has performed under the restructured terms for a consecutive twelve-month period. A loan may also be considered for removal from TDR status as a result of a subsequent restructure under certain restrictive circumstances. The removal of TDR designations must be approved by the Company's Special Asset Loan Committee. Loan modifications made under the Joint Guidance and CARES Act, as amended by the CAA, were suspended from TDR evaluation. Reserve for Unfunded Commitments - ​ Accrued Interest Receivable - ​ Premises and Equipment - Goodwill and Intangible Assets - Goodwill and Other Intangible Assets, Intangible assets with definite useful lives are amortized over their estimated useful lives, which range from 4 to 10 years, to their estimated residual values. Long-lived assets, including purchased intangible assets subject to amortization, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to estimated undiscounted future cash flows expected to be generated by the asset. If the carrying amount of an asset exceeds its estimated future cash flows, an impairment charge is recognized in the amount by which the carrying amount of the asset exceeds the fair value of the asset. Assets to be disposed of would be separately presented on the Company’s Consolidated Balance Sheets and reported at the lower of the carrying amount or fair value less costs to sell, would no longer depreciated. Management concluded that no circumstances indicating an impairment of these assets existed as of the balance sheet date. The Company performs the analysis annually on April 30 of each year at the reporting unit level whereby the Company compares the estimated fair value of the reporting unit to its carrying value. If the estimated fair value of a reporting unit exceeds its carrying value, goodwill is not considered impaired. The Company engaged a third-party valuation specialist to assist management in performing its annual goodwill impairment analysis. The last goodwill impairment analysis was conducted on April 30, 2021. To determine the fair value of a reporting unit, the Company utilizes a combination of two separate quantitative methods, the market value approach, which considers comparable publicly-traded companies, and the income approach which estimates future cash flows. Critical assumptions that are used as part of these calculations include: the selection of comparable publicly-traded companies and selection of market comparable acquisition transactions. In addition, other key assumptions include the discount rate, the forecast of future earnings and cash flows of the reporting unit, economic conditions, which impact the assumptions related to interest and growth rates, and loss rates, the cost savings expected to be realized by a market participant, the control premium associated with the reporting unit and a relative weight given to the valuations derived by the two valuation methods. At April 30, 2021, the Company determined that there was no impairment to its goodwill. The Company performed a sensitivity analysis on key assumptions and concluded that no impairment existed as of the balance sheet date. Foreclosed Properties Transfers of Financial Assets Bank Owned Life Insurance Derivatives During the normal course of business, the Company enters into commitments to originate mortgage loans whereby the interest rate on the loan is determined prior to funding (“rate lock commitments”). For commitments issued in connection with potential loans intended for sale, the Bank enters into positions of forward month MBS to be announced (“TBA”) contracts on a mandatory basis or on a one-to-one forward sales contract on a best efforts basis. The Company enters into TBA contracts in order to control interest rate risk during the period between the rate lock commitment and mandatory sale of the mortgage loan. Both the rate lock commitment and the forward TBA contract are considered to be derivatives. A mortgage loan sold on a best efforts basis is locked into a forward sales contract with a counterparty on the same day as the rate lock commitment to control interest rate risk during the period between the commitment and the sale of the mortgage loan. Both the rate lock commitment and the forward sales contract are considered to be derivatives. Mortgage banking derivatives as of December 31, 2021 and 2020 did not have a material impact on the Company’s Consolidated Financial Statements. The market values of rate lock commitments and best efforts forward delivery commitments are not readily ascertainable with precision because they are not actively traded in stand-alone markets. The Company determines the fair value of rate lock commitments, delivery contracts, and forward sales contracts of MBS by measuring the change in the value of the underlying asset, while taking into consideration the probability that the rate lock commitments will close or will be funded. Certain risks arise from the forward delivery contracts in that the counterparties to the contracts may not be able to meet the terms of the contracts. Additional risks inherent in mandatory delivery programs include the risk that, if the Company does not close the loans subject to rate lock commitments, it will still be obligated to deliver MBS to the counterparty under the forward sales agreement. Affordable Housing Entities - The Company invests in private investment funds that make equity investments in multifamily affordable housing properties that provide affordable housing and historic tax credits for these investments. The activities of these entities are financed with a combination of invested equity capital and debt. The Company accounts for its affordable housing entities using the proportional amortization method. Under the proportional amortization method, the Company amortizes the initial cost of the investment in proportion to the tax credits and other tax benefits received, and recognizes the net investment performance in the income statement as a component of income tax expense (benefit). For the years ended December 31, 2021 and 2020, the Company recognized amortization of $3.6 million and $3.0 million, respectively, and tax credits and tax savings of $4.3 ​ Stock Compensation Plan The Company’s outstanding stock options related to shares assumed with the acquisition of Access. For the options assumed, the fair value of the stock options was estimated based on the date of acquisition, using the Black-Scholes option valuation. The converted option price of the Company’s common stock at acquisition was used for determining the associated compensation expense for nonvested stock awards. The valuation was used in 2021, 2020, and 2019 to determine the valuation of the stock options. Key assumptions used in the valuation were dividend yield, expected life, expected volatility, and the risk free rate. For the years ended December 2021, 2020, and 2019, the fair value of PSUs are determined and fixed on the grant date based on the Company’s stock price, adjusted for the exclusion of dividend equivalents, and the Monte Carlo simulation valuation was used to determine the grant date fair value of PSUs granted. The fair value of RSAs and stock awards are based on the trading price of the Company’s stock on the date of the grant. ASC 718 requires the Company to estimate forfeitures when recognizing compensation expense and that this estimate of forfeitures be adjusted over the requisite service period or vesting schedule based on the extent to which actual forfeitures differ from such estimates. Changes in estimated forfeitures are recognized through a cumulative catch-up adjustment, which is recognized in the period of change, and also will affect the amo

ACQUISITIONS AND DISPOSITIONS [Abstract]
ACQUISITIONS AND DISPOSITIONS	2. ACQUISITIONS Access Acquisition On February 1, 2019, the Company completed its acquisition of Access National Corporation (and its subsidiaries), a bank holding company based in Reston, Virginia. Holders of shares of Access’s common stock received 0.75 shares of the Company’s common stock in exchange for each share of Access’s common stock, resulting in the Company issuing 15,842,026 shares of the Company’s common stock at a fair value of approximately $500.0 million. In addition, the Company paid cash of approximately $12,000 in lieu of fractional shares. The transaction was accounted for using the acquisition method of accounting and, accordingly, assets acquired, liabilities assumed, and consideration exchanged were recorded at estimated fair values on the acquisition date. Fair values are preliminary and subject to refinement for up to one year after the closing date of the acquisition, in accordance with ASC 350. The measurement period was formally closed as of February 1, 2020, and the Company did not make any measurement period adjustments in 2020. There were no merger-related costs associated with the acquisition of Access for the years ended December 31, 2021 and 2020. Merger-related costs associated with the acquisition of Access were $26.2 million for the year ended December 31, 2019. Such costs include legal and accounting fees, lease and contract termination expenses, system conversion, and employee severances, which have been expensed as incurred.

The Company has evaluated AFS securities in an unrealized loss position for credit related impairment at December 31, 2021 and 2020 and concluded no impairment existed based on several factors which included: (1) the majority of these securities are of high credit quality, (2) unrealized losses are primarily the result of market volatility, (3) the contractual terms of the investments do not permit the issuer(s) to settle the securities at a price less than the cost basis of each investment, (4) issuers continue to make timely principal and interest payments, and (5) the Company does not intend to sell any of the investments and the accounting standard of “more likely than not” has not been met for the Company to be required to sell any of the investments before recovery of its amortized cost basis. ​ Additionally, the majority of the Company’s MBS are issued by FNMA, FHLMC, and GNMA and do not have credit risk given the implicit and explicit government guarantees associated with these agencies. In addition, the non-agency mortgage-backed and asset-backed securities generally received a 20% SSFA rating. ​ The following table presents the amortized cost and estimated fair value of AFS securities as of December 31, 2021 and 2020, by contractual maturity (dollars in thousands).

See Note 1 “Summary of Significant Accounting Policies” for additional information on the Company’s policies for nonaccrual loans. ​ ​ Troubled Debt Restructurings ​ The CARES Act, as amended by the CAA, permits financial institutions to suspend requirements under GAAP for loan modifications to borrowers affected by COVID-19 that would otherwise be characterized as TDRs and suspend any determination related thereto if (i) the loan modification is made between March 1, 2020 and the earlier of January 1, 2022 or 60 days after the end of the COVID-19 emergency declaration and (ii) the applicable loan was not more than 30 days past due as of December 31, 2019. In addition, federal bank regulatory authorities also issued guidance to encourage financial institutions to make loan modifications for borrowers affected by COVID-19 and have assured financial institutions that they will neither receive supervisory criticism for such prudent loan modifications, nor be required by examiners to automatically categorize COVID-19-related loan modifications as TDRs. As of December 31, 2021, there were no material loans still under their modified terms. As of December 31, 2020, the Company had approximately $146.1 million in loans still under their modified terms. The Company’s modification program primarily included payment deferrals and interest only modifications. As of December 31, 2021, the Company has TDRs totaling $18.0 million with an estimated $859,000 of allowance for those loans for the current period. As of December 31, 2020, the Company had TDRs totaling $20.6 million with an estimated $1.6 million of allowance for those loans. ​ A TDR occurs when a lender, for economic or legal reasons, grants a concession to the borrower related to the borrower’s financial difficulties, that it would not otherwise consider. All loans that are considered to be TDRs are evaluated for credit losses in accordance with the Company’s ALLL methodology. For the years ended December 31, 2021 and 2020, the recorded investment in TDRs prior to modifications was not materially impacted by the modifications. ​ The following table provides a summary, by class, of TDRs that continue to accrue interest under the terms of the applicable restructuring agreement, which are considered to be performing, and TDRs that have been placed on nonaccrual status, which are considered to be nonperforming, as of December 31, 2021 and 2020 (dollars in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, 2021 ​ December 31, 2020 ​ No. of Recorded Outstanding No. of Recorded Outstanding ​ ​ Loans ​ Investment ​ Commitment ​ Loans ​ Investment ​ Commitment Performing ​ ​ ​ ​ Construction and Land Development 4 ​ $ 201 ​ $ — 4 ​ $ 215 ​ $ — Commercial Real Estate - Owner Occupied 3 ​ 572 ​ — 6 ​ 2,033 ​ 176 Commercial Real Estate - Non-Owner Occupied — ​ — ​ — 1 ​ 1,089 ​ — Commercial & Industrial — ​ — ​ — 4 ​ 727 ​ — Residential 1-4 Family - Commercial — ​ — ​ — 3 ​ 245 ​ — Residential 1-4 Family - Consumer 75 ​ 9,021 ​ — 77 ​ 8,943 ​ — Residential 1-4 Family - Revolving 3 ​ 265 ​ 4 3 ​ 277 ​ — Consumer 2 ​ 15 ​ — 3 ​ 22 ​ — Other Commercial ​ 1 ​ ​ 239 ​ ​ — ​ 1 ​ ​ 410 ​ ​ — Total performing 88 ​ $ 10,313 ​ $ 4 102 ​ $ 13,961 ​ $ 176 Nonperforming ​ ​ ​ ​ Commercial Real Estate - Owner Occupied 2 ​ $ 830 ​ $ — 1 ​ $ 20 ​ $ — Commercial Real Estate - Non-Owner Occupied ​ 3 ​ ​ 1,357 ​ ​ — ​ 1 ​ ​ 134 ​ ​ — Commercial & Industrial 3 ​ 729 ​ — 3 ​ 237 ​ — Residential 1-4 Family - Commercial 3 ​ 388 ​ — 4 ​ 1,296 ​ — Residential 1-4 Family - Consumer 24 ​ 4,239 ​ — 23 ​ 4,865 ​ — Residential 1-4 Family - Revolving 3 ​ 99 ​ — 3 ​ 103 ​ — Total nonperforming 38 ​ $ 7,642 ​ $ — 35 ​ $ 6,655 ​ $ — Total performing and nonperforming 126 ​ $ 17,955 ​ $ 4 137 ​ $ 20,616 ​ $ 176 ​ The Company considers a default of a TDR to occur when the borrower is 90 days past due following the restructure or a foreclosure and repossession of the applicable collateral occurs. During the years ended December 31, 2021 and 2020, the Company did not have any material loans that went into default that had been restructured in the twelve-month period prior to the time of default. ​ The following table shows, by class and modification type, TDRs that occurred during the year ended December 31, 2021 and 2020 (dollars in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ All Restructurings ​ ​ 2021 ​ 2020 ​ ​ Recorded ​ Recorded ​ ​ No. of ​ Investment at ​ No. of ​ Investment at ​ ​ Loans ​ Period End ​ Loans ​ Period End Modified to interest only, at a market rate ​ ​ Residential 1-4 Family - Commercial ​ — ​ $ — ​ 1 ​ ​ 644 Total interest only at market rate of interest — ​ $ — 1 ​ $ 644 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Term modification, at a market rate ​ ​ Commercial & Industrial — ​ $ — 3 ​ 103 Commercial Real Estate - Non-Owner Occupied 1 ​ ​ 153 — ​ — Residential 1-4 Family - Commercial — ​ — 1 ​ 294 Residential 1-4 Family - Consumer ​ 2 ​ ​ 101 ​ 4 ​ ​ 320 Consumer ​ — ​ ​ — ​ 1 ​ ​ 9 Total loan term extended at a market rate 3 ​ $ 254 9 ​ $ 726 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Term modification, below market rate ​ ​ Construction and Land Development ​ — ​ $ — ​ 1 ​ $ 34 Commercial & Industrial — ​ — 2 ​ 355 Residential 1-4 Family - Commercial ​ — ​ ​ — ​ 1 ​ ​ 287 Residential 1-4 Family - Consumer 12 ​ ​ 1,810 18 ​ 2,519 Residential 1-4 Family - Revolving — ​ — 2 ​ 275 Consumer 1 ​ 15 — ​ — Total loan term extended at a below market rate 13 ​ $ 1,825 24 ​ $ 3,470 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Interest rate modification, below market rate ​ ​ Residential 1-4 Family - Commercial 1 ​ $ 45 — ​ $ — Total interest only at below market rate of interest 1 ​ $ 45 — ​ $ — ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Total 17 ​ $ 2,124 34 ​ $ 4,840 ​ ​ Allowance for Loan and Lease Losses ​ ALLL on the loan portfolio is a material estimate for the Company. The Company estimates its ALLL on its loan portfolio on a quarterly basis. The Company models the ALLL using two primary segments, Commercial and Consumer. Each loan segment is further disaggregated into classes based on similar risk characteristics. The Company has identified the following classes within each loan segment: ● Commercial : Construction and Land Development, Commercial Real Estate – Owner Occupied, Commercial Real Estate – Non-Owner Occupied, Multifamily Real Estate, Commercial & Industrial, Residential 1-4 Family – Commercial, and Other Commercial ● Consumer : Residential 1-4 Family – Consumer, Residential 1-4 Family – Revolving, Auto, and Consumer ​ The following tables show the ALLL activity by loan segment for the years ended December 31, 2021 and 2020 (dollars in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Year Ended December 31, 2021 ​ Year Ended December 31, 2020 ​ ​ Commercial ​ Consumer ​ Total Commercial ​ Consumer ​ Total Balance at beginning of period ​ $ 117,403 ​ $ 43,137 ​ $ 160,540 $ 30,941 ​ $ 11,353 ​ $ 42,294 Impact of ASC 326 adoption on non-PCD loans ​ — ​ — ​ — ​ 4,432 ​ 40,666 ​ 45,098 Impact of ASC 326 adoption on PCD loans ​ — ​ — ​ — 1,752 ​ 634 ​ 2,386 Impact of adopting ASC 326 ​ — ​ — ​ — ​ 6,184 ​ 41,300 ​ 47,484 Loans charged-off ​ (5,186) ​ (4,897) ​ (10,083) (6,671) ​ (11,522) ​ (18,193) Recoveries credited to allowance ​ 4,915 ​ 3,303 ​ 8,218 3,517 ​ 3,238 ​ 6,755 Provision charged to operations ​ (39,230) ​ (19,658) ​ (58,888) 83,432 ​ (1,232) ​ 82,200 Balance at end of period ​ $ 77,902 ​ $ 21,885 ​ $ 99,787 ​ $ 117,403 ​ $ 43,137 ​ $ 160,540 ​ ​ ​ Credit Quality Indicators ​ Credit quality indicators are utilized to help estimate the collectability of each loan class within the Commercial and Consumer loan segments. For classes of loans within the Commercial segment, the primary credit quality indicator used for evaluating credit quality and estimating the ALLL is risk rating categories of Pass, Watch, Special Mention, Substandard, and Doubtful. For classes of loans within the Consumer segment, the primary credit quality indicator used for evaluating credit quality and estimating the ALLL is delinquency bands of Current, 30-59, 60-89, 90+, and Nonaccrual. While other credit quality indicators are evaluated and analyzed as part of the Company’s credit risk management activities, these indicators are primarily used in estimating the ALLL. The Company evaluates the credit risk of its loan portfolio on at least a quarterly basis. ​ Commercial Loans ​ The Company uses a risk rating system as the primary credit quality indicator for classes of loans within the Commercial segment. The risk rating system on a scale of 0 through 9 is used to determine risk level as used in the calculation of the ACL. The risk levels, as described below, do not necessarily follow the regulatory definitions of risk levels with the same name. A general description of the characteristics of the risk levels follows: ​ Pass is determined by the following criteria: ● Risk rated 0 loans have little or no risk and are with General Obligation Municipal Borrowers; ● Risk rated 1 loans have little or no risk and are generally secured by cash or cash equivalents; ● Risk rated 2 loans have minimal risk to well qualified borrowers and no significant questions as to safety; ● Risk rated 3 loans are satisfactory loans with strong borrowers and secondary sources of repayment; ● Risk rated 4 loans are satisfactory loans with borrowers not as strong as risk rated 3 loans and may exhibit a greater degree of financial risk based on the type of business supporting the loan. ​ Watch is determined by the following criteria: ● Risk rated 5 loans are watch loans that warrant more than the normal level of supervision and have the possibility of an event occurring that may weaken the borrower’s ability to repay; ​ Special Mention is determined by the following criteria: ● Risk rated 6 loans have increasing potential weaknesses beyond those at which the loan originally was granted and if not addressed could lead to inadequately protecting the Company’s credit position. ​ Substandard is determined by the following criteria: ● Risk rated 7 loans are substandard loans and are inadequately protected by the current sound worth or paying capacity of the obligor or the collateral pledged; these have well defined weaknesses that jeopardize the liquidation of the debt with the distinct possibility the Company will sustain some loss if the deficiencies are not corrected. ​ Doubtful is determined by the following criteria: ● Risk rated 8 loans are doubtful of collection and the possibility of loss is high but pending specific borrower plans for recovery, its classification as a loss is deferred until its more exact status is determined; ● Risk rated 9 loans are loss loans which are considered uncollectable and of such little value that their continuance as bankable assets is not warranted. ​ The table below details the amortized cost of the classes of loans within the Commercial segment by risk level and year of origination as of December 31, 2021 (dollars in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, 2021 ​ ​ ​ Term Loans Amortized Cost Basis by Origination Year ​ ​ ​ ​ ​ ​ ​ ​ 2021 ​ 2020 ​ 2019 ​ 2018 ​ 2017 ​ Prior ​ Revolving Loans ​ Total Construction and Land Development ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Pass ​ $ 430,764 ​ $ 218,672 ​ $ 39,937 ​ $ 40,128 ​ $ 11,299 ​ $ 50,908 ​ $ 22,996 ​ $ 814,704 Watch ​ ​ 395 ​ ​ 185 ​ ​ 12,923 ​ ​ 129 ​ ​ 349 ​ ​ 4,026 ​ ​ -

Core deposit intangibles are being amortized over the period of expected benefit, which ranges from 4 to 10 years, using an accelerated method. Other amortizable intangible assets are being amortized over the period of expected benefit, which ranges from 4 to 10 years, using various methods. The Company determined that there was no impairment to its goodwill or intangible assets. In the normal course of business, the Company routinely monitors the impact of the changes in the financial markets and includes these assessments in the Company’s goodwill impairment process. The Company analyzed its intangible assets on a quarterly basis throughout 2021, and concluded no impairment existed as of the balance sheet date. Information concerning intangible assets with a finite life is presented in the following table (dollars in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Gross ​ ​ Net ​ ​ Carrying ​ Accumulated ​ Carrying ​ ​ Value ​ Amortization ​ Value December 31, 2021 ​ ​ ​ Core deposit intangibles ​ $ 101,724 ​ $ 66,739 ​ $ 34,985 Other amortizable intangibles ​ 14,893 ​ 6,566 ​ 8,327 December 31, 2020 ​ ​ ​ Core deposit intangibles ​ $ 135,300 ​ $ 88,109 ​ $ 47,191 Other amortizable intangibles ​ 15,240 ​ 5,246 ​ 9,994 ​ Amortization expense of intangibles for the years ended December 31, 2021, 2020, and 2019 totaled $13.9 million, $16.6 million, and $18.5 million, respectively.

Leases [Abstract]
LEASES	​ 7. LEASES The Company enters into both lessor and lessee arrangements and determines if an arrangement is a lease at inception. As both a lessee and lessor, the Company elected the practical expedient permitted under the transition guidance within the standard to account for lease and non-lease components as a single lease component for all asset classes. Lessor Arrangements The Company’s lessor arrangements consist of sales-type and direct financing leases for equipment. Lease payment terms are fixed and are typically payable in monthly installments with terms ranging from 14 months to 125 months. The lease arrangements may contain renewal options and purchase options that allow the lessee to purchase the leased equipment at the end of the lease term. The leases generally do not contain non-lease components. The Company has no material sale leaseback transactions and no lease transactions with related parties. At lease inception the Company estimates the expected residual value of the leased property at the end of the lease term by considering both internal and third-party appraisals. In certain cases, the Company obtains lessee-provided residual value guarantees and third-party RVI to reduce its residual asset risk. At December 31, 2021 and December 31, 2020, the carrying value of residual assets covered by residual value guarantees and RVI was $23.0 million and $14.7 million, respectively. The net investment in sales-type and direct financing leases consists of the carrying amount of the lease receivables plus unguaranteed residual assets, net of unearned income and any deferred selling profit on direct financing leases. The lease receivables include the lessor’s right to receive lease payments and the guaranteed residual asset value the lessor expects to derive from the underlying assets at the end of the lease term. The Company’s net investment in sales-type and direct financing leases are included in “Loans held for investment, net of deferred fees and costs” on the Company’s Consolidated Balance Sheets. Lease income is recorded in “Interest and fees on loans” on the Company’s Consolidated Statements of Income. Total net investment in sales-type and direct financing leases consists of the following (dollars in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, 2021 ​ ​ December 31, 2020 Sales-type and direct financing leases: ​ ​ ​ ​ ​ ​ ​ Lease receivables, net of unearned income and deferred selling profit ​ $ 199,423 ​ ​ $ 141,180 Unguaranteed residual values, net of unearned income and deferred selling profit ​ ​ 8,911 ​ ​ ​ 4,796 Total net investment in sales-type and direct financing leases $ 208,334 ​ ​ $ 145,976 ​ ​ Lessee Arrangements The Company’s lessee arrangements consist of operating and finance leases; however, the majority of the leases have been classified as non-cancellable operating leases and are primarily for real estate leases with remaining lease terms of up to 24 years . The Company’s real estate lease agreements do not contain residual value guarantees and most agreements do not contain restrictive covenants. The Company does not have any material arrangements where the Company is in a sublease contract. Lessee arrangements with an initial term of 12 months or less are not recorded on the Consolidated Balance Sheets. The ROU assets and lease liabilities associated with operating and finance leases greater than 12 months are recorded in the Company’s Consolidated Balance Sheets; ROU assets within “Other assets” and lease liabilities within “Other liabilities.” ROU assets represent the Company’s right to use an underlying asset over the course of the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. The initial measurement of lease liabilities and ROU assets are the same for operating and finance leases. Lease liabilities are recognized at the commencement date based on the present value of the remaining lease payments, discounted using the incremental borrowing rate. As most of the Company’s leases do not provide an implicit rate, the Company uses an incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. ROU assets are recognized at commencement date based on the initial measurement of the lease liability, any lease payments made excluding lease incentives, and any initial direct costs incurred. Most of the Company’s operating leases include one or more options to renew and if the Company is reasonably certain to exercise those options, it would be included in the measurement of the operating ROU assets and lease liabilities. Lease expense for operating lease payments is recognized on a straight-line basis over the lease term and recorded in “Occupancy expenses” on the Company’s Consolidated Statements of Income. Finance lease expenses consist of straight-line amortization expense of the ROU Assets recognized over the lease term and interest expense on the lease liability. Total finance lease expenses for the amortization of the ROU assets are recorded in “Occupancy expenses” on the Company’s Consolidated Statements of Income and interest expense on the finance lease liability is recorded in “Interest on long-term borrowings” on the Company’s Consolidated Statements of Income.

Borrowings [Abstract]
BORROWINGS	9. BORROWINGS Short-term Borrowings The Company classifies all borrowings that will mature within a year from the date on which the Company enters into them as short-term borrowings. Total short-term borrowings consist primarily of securities sold under agreements to repurchase, which are secured transactions with customers and generally mature the day following the date sold, advances from the FHLB, and federal funds purchased (which are secured overnight borrowings from other financial institutions), and other lines of credit. ​ Total short-term borrowings as of December 31, 2021 and 2020 (dollars in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ 2021 ​ 2020 Securities sold under agreements to repurchase ​ $ 117,870 ​ $ 100,888 ​ Federal Funds Purchased ​ ​ — ​ ​ 150,000 ​ FHLB Advances ​ — ​ 100,000 ​ Total short-term borrowings ​ $ 117,870 ​ $ 350,888 ​ ​ ​ ​ ​ ​ ​ ​ ​ Average outstanding balance during the period ​ $ 113,030 ​ $ 213,932 ​ Average interest rate during the period ​ 0.10 % 0.79 % Average interest rate at end of period ​ 0.07 % 0.13 % ​ The Bank maintains federal funds lines with several correspondent banks; the available balance was $997.0 million and $847.0 million at December 31, 2021 and 2020, respectively. The Company maintains an alternate line of credit at a correspondent bank; the available balance was $25.0 million at both December 31, 2021 and 2020. The Company has certain restrictive covenants related to certain asset quality, capital, and profitability metrics associated with these lines and is in compliance with these covenants as of December 31, 2021 and 2020. Additionally, the Company had a collateral dependent line of credit with the FHLB of up to Long-term Borrowings During the fourth quarter of 2021, the company issued the 2031 Notes. The 2031 Notes were sold at par resulting in net proceeds, after underwriting discounts and offering expenses, of approximately million. The Company used a portion of the net proceeds from the 2031 Notes issuance to repay its outstanding In connection with several previous bank acquisitions, the Company issued $58.5 million and acquired $87.0 million of trust preferred capital notes. Most recently, in connection with the acquisition of Access on February 1, 2019, the Company acquired additional trust preferred capital notes totaling $5.0 million. The remaining fair value discount on all acquired trust preferred capital notes was $13.3 million and $14.1 million at December 31, 2021 and 2020, respectively. On August 23, 2012, the Company modified its fixed rate FHLB advances to floating rate advances, which resulted in reducing the Company’s FHLB borrowing costs. In connection with this modification, the Company incurred a prepayment penalty of $19.6 million on the original advances which was deferred and to be amortized over the term of the modified advances using the effective rate method. On August 29, 2019, the Company repaid the floating rate FHLB advances. In connection with this repayment, the remaining unamortized prepayment penalty of $7.4 million was immediately recognized as a component of noninterest expense during the third quarter of 2019. In response to the current interest rate environment, the Company prepaid a $200.0 million long-term FHLB advance on February 26, 2021 and $550.0 million of long-term FHLB advances in 2020, which resulted in prepayment penalties of $14.7 million and $31.2 million, respectively. In addition, on November 30, 2020, the Company redeemed $8.5 million in subordinated debt that was originally acquired as part of the Xenith acquisition. ​ ​ Total long-term borrowings consist of the following as of December 31, 2021 (dollars in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Spread to ​ ​ ​ ​ ​ ​ ​ ​ ​ Principal ​ 3-Month LIBOR ​ Rate (1) ​ Maturity ​ Investment (2) Trust Preferred Capital Securities ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Trust Preferred Capital Note - Statutory Trust I ​ $ 22,500 2.75 % 2.96 % 6/17/2034 ​ $ 696 Trust Preferred Capital Note - Statutory Trust II ​ 36,000 1.40 % 1.61 % 6/15/2036 ​ 1,114 VFG Limited Liability Trust I Indenture ​ 20,000 2.73 % 2.94 % 3/18/2034 ​ 619 FNB Statutory Trust II Indenture ​ 12,000 3.10 % 3.31 % 6/26/2033 ​ 372 Gateway Capital Statutory Trust I ​ 8,000 3.10 % 3.31 % 9/17/2033 ​ 248 Gateway Capital Statutory Trust II ​ 7,000 2.65 % 2.86 % 6/17/2034 ​ 217 Gateway Capital Statutory Trust III ​ 15,000 1.50 % 1.71 % 5/30/2036 ​ 464 Gateway Capital Statutory Trust IV ​ 25,000 1.55 % 1.76 % 7/30/2037 ​ 774 MFC Capital Trust II ​ 5,000 2.85 % 3.06 % 1/23/2034 ​ 155 Total Trust Preferred Capital Securities ​ $ 150,500 ​ $ 4,659 Subordinated Debt (3)(4) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ 2031 Subordinated Debt ​ ​ 250,000 ​ - % 2.875 % 12/15/2031 ​ ​ ​ Total Subordinated Debt (5) ​ $ 250,000 ​ ​ ​ ​ ​ ​ ​ ​ ​ Fair Value Discount (6) ​ ​ (16,435) ​ ​ ​ ​ ​ ​ ​ ​ ​ Investment in Trust Preferred Capital Securities ​ ​ 4,659 ​ ​ ​ ​ ​ ​ ​ ​ ​ Total Long-term Borrowings ​ $ 388,724 ​ ​ ​ ​ ​ ​ ​ ​ ​ (1) Rate as of December 31, 2021.

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	10. COMMITMENTS AND CONTINGENCIES Litigation Matters In the ordinary course of its operations, the Company and its subsidiaries are involved in various legal and regulatory proceedings. The amount, if any, of ultimate liability with respect to such matters cannot be determined. Despite the uncertainties of such litigation and investigations, and based on the information presently available and after consultation with legal counsel, management believes that the ultimate outcome in such legal proceedings, in the aggregate, will not have a material adverse effect on the business or the financial condition or results of operations of the Company subject to the potential outcomes of the matter discussed below. On February 9, 2022, pursuant to the CFPB’s NORA process, the CFPB Office of Enforcement notified the Bank that it is considering recommending that the CFPB take legal action against the Bank in connection with alleged violations of Regulation E, 12 C.F.R. § 1005.17, and the Consumer Financial Protection Act, 12 U.S.C. §§ 5531 and 5536, in connection with the Bank’s overdraft practices and policies. The purpose of the NORA process is to ensure that potential subjects of enforcement actions have the opportunity to respond to alleged violations and present their positions to the CFPB before an enforcement action is recommended or commenced. Should the CFPB commence a legal action, it may seek restitution to affected customers, civil monetary penalties, injunctive relief, or other corrective action. While a loss is reasonably possible related to this matter, an estimate is not possible at this time. The Company and the Bank are unable at this time to determine how or when the matter will be resolved or the significance, if any, to our business, financial condition, or results of operations. Financial Instruments with Off-Balance Sheet Risk The Company is a party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers and to reduce its own exposure to fluctuations in interest rates. These financial instruments include commitments to extend credit and letters of credit. These instruments involve elements of credit and interest rate risk in excess of the amount recognized on the Company’s Consolidated Balance Sheets. The contractual amounts of these instruments reflect the extent of the Company’s involvement in particular classes of financial instruments. The Company’s exposure to credit loss in the event of nonperformance by the other party to the financial instruments for commitments to extend credit and letters of credit written is represented by the contractual amount of these instruments. The Company uses the same credit policies in making commitments and conditional obligations as it does for on-balance sheet instruments. Unless noted otherwise, the Company does not require collateral or other security to support off-balance sheet financial instruments with credit risk. The Company considers credit losses related to off-balance sheet commitments by undergoing a similar process in evaluating losses for loans that are carried on the balance sheet. The Company considers historical loss and funding information, current and future economic conditions, risk ratings, and past due status among other factors in the consideration of expected credit losses in the Company’s off-balance sheet commitments to extend credit. The Company also records an indemnification reserve that includes balances relating to mortgage loans previously sold based on historical statistics and loss rates. As of December 31, 2021 and 2020, the Company’s reserves for unfunded commitment and indemnification were $8.4 million and $10.8 million, respectively. Commitments to extend credit are agreements to lend to customers as long as there are no violations of any conditions established in the contracts. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Because many of the commitments may expire without being completely drawn upon, the total commitment amounts do not necessarily represent future cash requirements. Letters of credit are conditional commitments issued by the Company to guarantee the performance of customers to third parties. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loans to customers. ​ ​ The following table presents the balances of commitments and contingencies as of December 31, (dollars in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ 2021 2020 Commitments with off-balance sheet risk: ​ ​ Commitments to extend credit (1) ​ $ 5,825,557 ​ $ 4,722,412 Letters of credit ​ 152,506 ​ 161,827 Total commitments with off-balance sheet risk ​ $ 5,978,063 ​ $ 4,884,239 (1) Includes unfunded overdraft protection. ​ ​ ​ ​ ​ ​ ​ As of December 31, 2021, the Company had approximately $187.4 million in deposits in other financial institutions of which $82.3 million served as collateral for cash flow and loan swap derivatives. As of December 31, 2020, the Company had approximately $290.5 million in deposits in other financial institutions of which $251.0 million served as collateral for cash flow and loan swap derivatives. For asset/liability management purposes, the Company uses interest rate contracts to hedge various exposures or to modify the interest rate characteristics of various balance sheet accounts.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVES	11. DERIVATIVES The Company is exposed to economic risks arising from its business operations and uses derivatives primarily to manage risk associated with changing interest rates, and to assist customers with their risk management objectives. The Company designates certain derivatives as hedging instruments in a qualifying hedge accounting relationship (cash flow or fair value hedge). The remaining are classified as free-standing derivatives that do not qualify for hedge accounting and consist of interest rate contracts, which include loan swaps and interest rate cap agreements, as well as interest rate lock commitments. Derivatives Counterparty Credit Risk Derivative instruments contain an element of credit risk that arises from the potential failure of a counterparty to perform according to the terms of the contract. The Company’s exposure to derivative counterparty credit risk, at any point in time, is equal to the amount reported as a derivative asset on the Company’s Consolidated Balance Sheets, assuming no recoveries of underlying collateral. The Company clears certain OTC derivatives with central clearinghouses through FCMs due to applicable regulatory requirements, which reduces the Company’s counterparty risk. ​ The Company also enters into legally enforceable master netting agreements and collateral agreements, where possible, with certain derivative counterparties to mitigate the risk of default on a bilateral basis. These bilateral agreements typically provide the right to offset exposures and require one counterparty to post collateral on derivative instruments in a net liability position to the other counterparty. For the OTC derivatives cleared with central clearinghouses, the variation margin is treated as settlement of the related derivatives fair values. Cash Flow Hedges The Company designates derivatives as cash flow hedges when they are used to manage exposure to variability in cash flows related to forecasted transactions on variable rate financial instruments. The Company uses interest rate swap agreements as part of its hedging strategy by exchanging a notional amount, equal to the principal amount of the borrowings or commercial loans, for fixed-rate interest based on benchmarked interest rates. The original terms and conditions of the interest rate swaps vary and range in length. Amounts receivable or payable are recognized as accrued under the terms of the agreements. ​ All swaps were entered into with counterparties that met the Company’s credit standards, and the agreements contain collateral provisions protecting the at-risk party. The Company concluded that the credit risk inherent in the contract is not significant. ​ For derivatives designated and qualifying as cash flow hedges, ineffectiveness is not measured or separately disclosed. Rather, as long as the hedging relationship continues to qualify for hedge accounting, the entire change in the fair value of the hedging instrument is recorded in OCI and recognized in earnings as the hedged transaction affects earnings. Derivative amounts affecting earnings are recognized consistent with the classification of the hedged item. During the period ended December 31, 2021, the Company executed four interest rate swaps designated and qualifying as cash flow hedges of the Company’s forecasted variable interest receipts on variable rate loans due to changes in the interest rate with a notional amount of $500 million at December 31, 2021. The Company did t have any derivatives designated as cash flow hedges at December 31, 2020. For each agreement, the Company receives interest at a fixed rate and pays at a variable rate. During the period ended December 31, 2020, the Company terminated interest rate swaps designated as cash flow hedges prior to their respective maturity dates resulting in net losses of approximately $1.8 million, which resulted in the losses being recognized immediately in earnings as the forecasted transactions will not occur. Fair Value Hedges Derivatives are designated as fair value hedges when they are used to manage exposure to changes in the fair value of certain financial assets and liabilities, referred to as the hedged items, which fluctuate in value as a result of movements in interest rates. ​ Loans : ​ AFS Securities: The Company has entered into a swap agreement to hedge the interest rate risk on a portion of its fixed rate AFS securities. For the years ended December 31, 2021 and 2020, the aggregate notional amount of the related hedged items of the AFS securities totaled ​ The Company applies hedge accounting in accordance with ASC 815, Derivatives and Hedging, and the fair value hedge and the underlying hedged item, attributable to the risk being hedged, are recorded at fair value with unrealized gains and losses being recorded on the Company’s Consolidated Statements of Income. The Company assesses the effectiveness of each hedging relationship by comparing the changes in fair value or cash flows on the derivative hedging instrument with the changes in fair value or cash flows on the designated hedged item or transactions for the risk being hedged. If a hedging relationship ceases to qualify for hedge accounting, the relationship is discontinued and future changes in the fair value of the derivative instrument are recognized in current period earnings. For a discontinued or terminated fair value hedging relationship, all remaining basis adjustments to the carrying amount of the hedged item are amortized to interest income or expense over the remaining life of the hedged item consistent with the amortization of other discounts or premiums. Previous balances deferred in AOCI from discontinued or terminated cash flow hedges are reclassified to interest income or expense as the hedged transactions affect earnings or over the originally specified term of the hedging relationship. The Company’s hedges continue to be highly effective and had no material impact on the Consolidated Statements of Income. Interest Rate Contracts During the normal course of business, the Company enters into interest rate contracts with borrowers to help meet their financing needs. Upon entering into interest rate contracts, the Company enters into offsetting positions with a third party in order to minimize interest rate risk. These interest rate contracts qualify as financial derivatives with fair values as reported in “Other Assets” and “Other Liabilities” on the Company’s Consolidated Balance Sheets. ​ The following table summarizes key elements of the Company’s derivative instruments as of December 31, 2021 and 2020, segregated by derivatives that are considered accounting hedges and those that are not (dollars in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, 2021 December 31, 2020 ​ ​ ​ ​ ​ Derivative (2) ​ ​ ​ ​ Derivative (2) ​ Notional or ​ ​ ​ ​ Notional or ​ ​ ​ ​ ​ ​ Contractual ​ ​ ​ ​ ​ ​ ​ Contractual ​ ​ ​ ​ ​ ​ ​ ​ Amount (1) ​ Assets ​ Liabilities ​ Amount (1) ​ Assets ​ Liabilities Derivatives designated as accounting hedges: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Interest rate contracts: (3) ​ ​ ​ ​ ​ ​ ​ ​ ​ Cash flow hedges ​ $ 500,000 ​ $ — ​ $ — ​ $ — ​ $ — ​ $ — Fair value hedges ​ 138,606 ​ — ​ 5,387 ​ 124,726 ​ — ​ 12,483 Derivatives not designated as accounting hedges: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Interest rate contracts (3) ​ 5,017,574 ​ 73,696 ​ 49,051 ​ 4,712,906 ​ 163,360 ​ 163,360 (1) Notional amounts are not recorded on the Company’s Consolidated Balance Sheets and are generally used only as a basis on which interest and other payments are determined. (2) Balances represent fair value of derivative financial instruments. (3) The Company’s cleared derivatives are classified as a single-unit of accounting, resulting in the fair value of the designated swap being reduced by the variation margin, which is treated as settlement of the related derivatives fair value for accounting purposes and is reported on a net basis at December 31, 2021. The previous periods presented do not include the offsetting impact of variation margin. ​ The following table summarizes the carrying value of the Company’s hedged assets in fair value hedges and the associated cumulative basis adjustments included in those carrying values as of December 31, 2021 and 2020 (dollars in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, 2021 ​ December 31, 2020 ​ ​ ​ Cumulative ​ Cumulative ​ ​ ​ ​ ​ Amount of Basis ​ ​ ​ Amount of Basis ​ ​ ​ ​ ​ Adjustments ​ ​ ​ Adjustments ​ ​ ​ ​ ​ Included in the ​ ​ ​ Included in the ​ ​ Carrying Amount ​ Carrying ​ Carrying Amount ​ Carrying ​ ​ of Hedged ​ Amount of the ​ of Hedged ​ Amount of the ​ ​ Assets/(Liabilities) ​ Hedged ​ Assets/(Liabilities) ​ Hedged ​ ​ Amount (1) Assets/(Liabilities) ​ Amount (1) Assets/(Liabilities) Line items on the Consolidated Balance Sheets in which the hedged item is included: ​ ​ ​ ​ Securities available-for-sale (1) (2) ​ $ 112,562 ​ $ 4,051 ​ $ 166,413 ​ $ 7,297 Loans ​ 88,606 ​ 546 ​ 74,726 ​ 5,088 (1) These amounts include the amortized cost basis of the investment securities designated in hedging relationships for which the hedged item is the last layer expected to be remaining at the end of the hedging relationship. For the periods ended December 31, 2021 and 2020, the amortized cost basis of this portfolio was $113 million and $166 million, respectively, and the cumulative basis adjustment associated with this hedge was $4.1 million and $7.3 million, respectively. The amount of the designated hedged item at December 31, 2021 and 2020 totaled $50 million. (2) Carrying value represents amortized cost. ​

REGULATORY MATTERS AND CAPITAL

Regulatory Capital Requirements [Abstract]
REGULATORY MATTERS AND CAPITAL	13. REGULATORY MATTERS AND CAPITAL Capital resources represent funds, earned or obtained, over which financial institutions can exercise greater or longer control in comparison with deposits and borrowed funds. Management seeks to maintain a capital structure that will assure an adequate level of capital to support anticipated asset growth and to absorb potential losses, yet allow management to effectively leverage its capital to maximize return to shareholders. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on financial statements of the Company and the Bank. Under capital adequacy guidelines and the regulatory framework for PCA, the Company and the Bank must meet specific capital guidelines that involve quantitative measures of their assets, liabilities, and certain off-balance sheet items as calculated under regulatory accounting practices. The capital amounts and classifications are also subject to qualitative judgments by the regulators about components, risk weightings, and other factors. PCA provisions are not applicable to financial holding companies and bank holding companies, but only to their bank subsidiaries. As of December 31, 2021 and 2020, the most recent notification from the FRB categorized the Bank as “well capitalized” under the regulatory framework for PCA. To be categorized as “well-capitalized,” an institution must maintain minimum total risk-based, Tier 1 risk-based, Tier 1 leverage, and common equity Tier 1 ratios as set forth in the following tables. There are no conditions or events since that notification that management believes have changed the Bank’s category. On March 27, 2020, the banking agencies issued an interim final rule that allows the Company to phase in the impact of adopting the CECL methodology up to two years, with a three-year transition period to phase out the cumulative benefit to regulatory capital provided during the two-year delay. The Company is allowed to include the impact of the CECL transition, which is defined as the CECL Day 1 impact to capital plus 25% of the Company’s provision for credit losses during 2020, in regulatory capital through 2021. The Company elected to phase in the regulatory capital impact as permitted under the aforementioned interim final rule. Beginning in 2022, the transition amount will begin to impact regulatory capital by phasing it in over a three-year period ending in 2024. ​ The Company and the Bank’s capital amounts and ratios are also presented in the following table at December 31, 2021 and 2020 (dollars in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Required in Order to Be ​ ​ ​ ​ ​ ​ ​ Required for Capital ​ Well Capitalized Under ​ ​ Actual ​ Adequacy Purposes ​ PCA ​ Amount Ratio Amount Ratio Amount Ratio As of December 31, 2021 ​ ​ ​ Common equity Tier 1 capital to risk weighted assets: ​ ​ ​ Consolidated ​ $ 1,569,752 10.24 % $ 689,832 ​ 4.50% ​ NA ​ NA ​ Atlantic Union Bank ​ 1,990,753 13.03 % 687,520 ​ 4.50% ​ 993,085 ​ 6.50% ​ Tier 1 capital to risk weighted assets: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Consolidated ​ 1,736,108 11.32 % 920,199 ​ 6.00% ​ NA ​ NA ​ Atlantic Union Bank ​ 1,990,753 13.03 % 916,694 ​ 6.00% ​ 1,222,258 ​ 8.00% ​ Total capital to risk weighted assets: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Consolidated ​ 2,173,543 14.17 % 1,227,124 ​ 8.00% ​ NA ​ NA ​ Atlantic Union Bank ​ 2,044,123 13.38 % 1,222,196 ​ 8.00% ​ 1,527,745 ​ 10.00% ​ Tier 1 capital to average adjusted assets: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Consolidated ​ 1,736,108 9.01 % 770,747 ​ 4.00% ​ NA ​ NA ​ Atlantic Union Bank ​ 1,990,753 10.37 % 767,889 ​ 4.00% ​ 959,862 ​ 5.00% ​ As of December 31, 2020 ​ ​ ​ Common equity Tier 1 capital to risk weighted assets: ​ ​ ​ Consolidated ​ $ 1,512,507 10.26 % $ 663,380 4.50% ​ NA NA ​ Atlantic Union Bank ​ 1,824,693 12.42 % 661,121 4.50% ​ 954,952 6.50% ​ Tier 1 capital to risk weighted assets: ​ ​ ​ ​ Consolidated ​ 1,678,863 11.39 % 884,388 6.00% ​ NA NA ​ Atlantic Union Bank ​ 1,824,693 12.42 % 881,494 6.00% ​ 1,175,326 8.00% ​ Total capital to risk weighted assets: ​ ​ ​ ​ Consolidated ​ 2,063,356 14.00 % 1,179,061 8.00% ​ NA NA ​ Atlantic Union Bank ​ 1,924,016 13.09 % 1,175,869 8.00% ​ 1,469,837 10.00% ​ Tier 1 capital to average adjusted assets: ​ ​ ​ ​ Consolidated ​ 1,678,863 8.95 % 750,330 4.00% ​ NA NA ​ Atlantic Union Bank ​ 1,824,693 9.75 % 748,592 4.00% ​ 935,740 5.00% ​ ​

FAIR VALUE MEASUREMENTS

FAIR VALUE MEASUREMENTS	12 Months Ended
	Dec. 31, 2021
Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENTS	14. FAIR VALUE MEASUREMENTS The Company follows ASC 820 to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures. ASC 820 clarifies that fair value of certain assets and liabilities is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between willing market participants. ASC 820 specifies a hierarchy of valuation techniques based on whether the inputs to those valuation techniques are observable or unobservable. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect the Company’s market assumptions. The three levels of the fair value hierarchy under ASC 820 based on these two types of inputs are as follows: ​ ​ Level 1 Valuation is based on quoted prices in active markets for identical assets and liabilities. Level 2 Valuation is based on observable inputs including quoted prices in active markets for similar assets and liabilities, quoted prices for identical or similar assets and liabilities in less active markets, and model-based valuation techniques for which significant assumptions can be derived primarily from or corroborated by observable data in the markets. Level 3 Valuation is based on model-based techniques that use one or more significant inputs or assumptions that are unobservable in the market. These unobservable inputs reflect the Company’s assumptions about what market participants would use and information that is reasonably available under the circumstances without undue cost and effort. ​ Assets and Liabilities Measured at Fair Value on a Recurring Basis The following describes the valuation techniques used by the Company to measure certain financial assets and liabilities recorded at fair value on a recurring basis in the financial statements. Derivative Instruments As discussed in Note 11 “Derivatives,” the Company records derivative instruments at fair value on a recurring basis. The Company utilizes derivative instruments as part of the management of interest rate risk to modify the re-pricing characteristics of certain portions of the Company’s interest-bearing assets and liabilities. The Company has contracted with a third-party vendor to provide valuations for derivatives using standard valuation techniques and therefore classifies such valuations as Level 2. Third party valuations are validated by the Company using Bloomberg Valuation Service’s derivative pricing functions. No material differences were identified during the validation as of December 31, 2021 and 2020. The Company has considered counterparty credit risk in the valuation of its derivative assets and has considered its own credit risk in the valuation of its derivative liabilities. Mortgage banking derivatives as of December 31, 2021 and 2020 did not have a material impact on the Company’s Consolidated Financial Statements. ​ AFS Securities AFS securities are recorded at fair value on a recurring basis. Fair value measurement is based upon quoted market prices, when available (Level 1). If quoted market prices are not available, fair values are measured utilizing independent valuation techniques of identical or similar securities for which significant assumptions are derived primarily from or corroborated by observable market data (Level 2). If the inputs used to provide the evaluation for certain securities are unobservable and/or there is little, if any, market activity, then the security would fall to the lowest level of the hierarchy (Level 3). ​ The Company’s investment portfolio is primarily valued using fair value measurements that are considered to be Level 2. The Company has contracted with a third-party portfolio accounting service vendor for valuation of its securities portfolio. The vendor’s primary source for security valuation is ICE, which evaluates securities based on market data. ICE utilizes evaluated pricing models that vary by asset class and include available trade, bid, and other market information. Generally, the methodology includes broker quotes, proprietary models, vast descriptive terms and conditions databases, as well as extensive quality control programs. The vendor utilizes proprietary valuation matrices for valuing all municipals securities. The initial curves for determining the price, movement, and yield relationships within the municipal matrices are derived from industry benchmark curves or sourced from a municipal trading desk. The securities are further broken down according to issuer, credit support, state of issuance, and rating to incorporate additional spreads to the industry benchmark curves. The Company primarily uses Bloomberg Valuation Service, an independent information source that draws on quantitative models and market data contributed from over 4,000 market participants, to validate third party valuations. Any material differences between valuation sources are researched by further analyzing the various inputs that are utilized by each pricing source. No material differences were identified during the validation as of December 31, 2021 and 2020. The carrying value of restricted FRB and FHLB stock approximates fair value based on the redemption provisions of each entity and is therefore excluded from the table below. Loans Held for Sale Residential loans originated for sale in the open market are carried at fair value. Fair value is based on the price secondary markets are currently offering for similar loans using observable market data which is not materially different than cost due to the short duration between origination and sale (Level 2). Gains and losses on the sale of loans are recorded in current period earnings as a component of “Mortgage banking income” on the Company’s Consolidated Statements of Income. ​ The following table presents the balances of financial assets and liabilities measured at fair value on a recurring basis at December 31, 2021 and 2020 (dollars in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Fair Value Measurements at December 31, 2021 using ​ ​ ​ Significant ​ ​ ​ ​ ​ ​ Quoted Prices in ​ Other ​ Significant ​ ​ ​ ​ ​ Active Markets for ​ Observable ​ Unobservable ​ ​ ​ ​ ​ Identical Assets ​ Inputs ​ Inputs ​ ​ ​ ​ ​ Level 1 ​ Level 2 ​ Level 3 ​ Balance ASSETS ​ ​ ​ ​ ​ AFS securities: ​ ​ ​ ​ ​ U.S. government and agency securities ​ $ 64,474 ​ $ 9,375 ​ $ — ​ $ 73,849 Obligations of states and political subdivisions ​ — ​ 1,008,396 ​ — ​ 1,008,396 Corporate and other bonds (1) ​ — ​ 153,376 ​ — ​ 153,376 MBS ​ — ​ 2,244,389 ​ — ​ 2,244,389 Other securities ​ — ​ 1,640 ​ — ​ 1,640 LHFS ​ — ​ 20,861 ​ — ​ 20,861 Derivatives: ​ ​ ​ ​ Interest rate contracts ​ — ​ 73,696 ​ — ​ 73,696 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ LIABILITIES ​ ​ ​ ​ Derivatives: ​ ​ ​ ​ Interest rate contracts ​ $ — ​ $ 49,051 ​ $ — ​ $ 49,051 Fair value hedges ​ — ​ 5,387 ​ — ​ 5,387 (1) Other bonds include asset-backed securities. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Fair Value Measurements at December 31, 2020 using ​ ​ ​ Significant ​ ​ ​ ​ ​ ​ Quoted Prices in ​ Other ​ Significant ​ ​ ​ ​ ​ Active Markets for ​ Observable ​ Unobservable ​ ​ ​ ​ ​ Identical Assets ​ Inputs ​ Inputs ​ ​ ​ ​ ​ Level 1 ​ Level 2 ​ Level 3 ​ Balance ASSETS ​ ​ ​ ​ ​ AFS securities: ​ ​ ​ ​ ​ U.S. government and agency securities ​ $ — ​ $ 13,394 ​ $ — ​ $ 13,394 Obligations of states and political subdivisions ​ ​ — ​ ​ 837,326 ​ ​ — ​ ​ 837,326 Corporate and other bonds (1) ​ — ​ 151,078 ​ — ​ 151,078 MBS ​ — ​ 1,536,996 ​ — ​ 1,536,996 Other securities ​ — ​ 1,625 ​ — ​ 1,625 LHFS ​ ​ — ​ ​ 96,742 ​ ​ — ​ ​ 96,742 Derivatives: ​ ​ ​ ​ Interest rate contracts ​ — ​ 163,360 ​ — ​ 163,360 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ LIABILITIES ​ ​ ​ ​ Derivatives: ​ ​ ​ ​ Interest rate contracts ​ $ — ​ $ 163,360 ​ $ — ​ $ 163,360 Fair value hedges ​ — ​ 12,483 ​ — ​ 12,483 (1) Other bonds include asset-backed securities. ​ Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis Certain assets are measured at fair value on a nonrecurring basis in accordance with U.S. GAAP. Adjustments to the fair value of these assets usually result from the application of lower-of-cost-or-market accounting or write-downs of individual assets after they are evaluated for impairment. The primary assets accounted for at fair value on a nonrecurring basis are related to foreclosed properties, former bank premises, and collateral-dependent loans that are individually assessed. When the asset is secured by real estate, the Company measures the fair value utilizing an income or market valuation approach based on an appraisal conducted by an independent, licensed appraiser using observable market data. Management may discount the value from the appraisal in determining the fair value if, based on its understanding of the market conditions, the collateral had been impaired below the appraised value (Level 3). The assets for which a nonrecurring fair value measurement was recorded during the period ended December 31, 2021 and 2020 was million, respectively. The nonrecurring valuation adjustments for these assets did not have a material impact on the Company’s consolidated financial statements. Fair Value of Financial Instruments ASC 825, Financial Instruments Cash and Cash Equivalents For those short-term instruments, the carrying amount is a reasonable estimate of fair value. ​ HTM Securities The Company’s investment portfolio is primarily valued using fair value measurements that are considered to be Level 2. The Company has contracted with a third-party portfolio accounting service vendor for valuation of its securities portfolio. The vendor’s primary source for security valuation is ICE, which evaluates securities based on market data. ICE utilizes evaluated pricing models that vary by asset class and include available trade, bid, and other market information. Generally, the methodology includes broker quotes, proprietary models, vast descriptive terms and conditions databases, as well as extensive quality control programs. The vendor utilizes proprietary valuation matrices for valuing all municipals securities. The initial curves for determining the price, movement, and yield relationships within the municipal matrices are derived from industry benchmark curves or sourced from a municipal trading desk. The securities are further broken down according to issuer, credit support, state of issuance, and rating to incorporate additional spreads to the industry benchmark curves. The Company primarily uses Bloomberg Valuation Service, an independent information source that draws on quantitative models and market data contributed from over 4,000 market participants, to validate third party valuations. Any material differences between valuation sources are researched by further analyzing the various inputs that are utilized by each pricing source. No material differences were identified during the validation as of December 31, 2021 and 2020. The Company’s Level 3 securities are a result of the Access acquisition and are comprised of asset-backed securities and municipal bonds. Valuations of the asset-backed securities are provided by a third party vendor specializing in the SBA markets, and are based on underlying loan pool information, market data, and recent trading activity for similar securities. Valuations of the municipal bonds are provided by a third party vendor that specializes in hard-to-value securities, and are based on a discounted cash flow model and considerations for the complexity of the instrument, likelihood it will be called and credit ratings. The Company reviews the valuation of both security types for reasonableness in the context of market conditions and to similar bonds in the Company’s portfolio. Any material differences between valuation sources are researched by further analyzing the various inputs that are utilized by each pricing source. No material differences were identified during the validation as of December 31, 2021 and 2020. Loans and Leases The fair value of loans and leases were estimated using an exit price, representing the amount that would be expected to be received if the Company sold the loans and leases. The fair value of performing loans and leases were estimated through use of discounted cash flows. Credit loss assumptions were based on market PD/LGD for loan and lease cohorts. The discount rate was based primarily on recent market origination rates. Fair value of loans and leases individually assessed and their respective levels within the fair value hierarchy are described in the previous section related to fair value measurements of assets that are measured on a nonrecurring basis. Bank Owned Life Insurance The carrying value of BOLI approximates fair value. The Company records these policies at their cash surrender value, which is estimated using information provided by insurance carriers. Deposits The fair value of demand deposits, savings accounts, and certain money market deposits is the amount payable on demand at the reporting date. The fair value of certificates of deposits were valued using a discounted cash flow calculation that includes a market rate analysis of the current rates offered by market participants for certificates of deposits that mature in the same period. Accrued Interest The carrying amounts of accrued interest approximate fair value. ​ The carrying values and estimated fair values of the Company’s financial instruments as of December 31, 2021 and 2020 are as follows (dollars in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Fair Value Measurements at December 31, 2021 using ​ ​ ​ Quoted Prices Significant ​ ​ ​ ​ ​ ​ ​ ​ ​ in Active ​ Other ​ Significant ​ ​ ​ ​ ​ ​ ​ ​ Markets for ​ Observable ​ Unobservable ​ Total Fair ​ ​ ​ ​ ​ Identical Assets ​ Inputs ​ Inputs ​ Value ​ ​ Carrying ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Value ​ Level 1 ​ Level 2 ​ Level 3 ​ Balance ASSETS ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Cash and cash equivalents ​ $ 802,501 ​ $ 802,501 ​ $ — ​ $ — ​ $ 802,501 AFS securities ​ 3,481,650 ​ 64,474 ​ 3,417,176 ​ — ​ 3,481,650 HTM securities ​ 628,000 ​ — ​ 686,733 ​ 7,041 ​ 693,774 Restricted stock ​ 76,825 ​ — ​ 76,825 ​ — ​ 76,825 LHFS ​ 20,861 ​ — ​ 20,861 ​ — ​ 20,861 Net loans ​ 13,096,056 ​ — ​ — ​ 12,861,274 ​ 12,861,274 Derivatives: ​ ​ ​ ​ ​ Interest rate contracts ​ 73,696 ​ — ​ 73,696 ​ — ​ 73,696 Accrued interest receivable ​ 65,015 ​ — ​ 65,015 ​ — ​ 65,015 BOLI ​ 431,517 ​ — ​ 431,517 ​ — ​ 431,517 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ LIABILITIES ​ ​ ​ ​ ​ Deposits ​ $ 16,611,068 ​ $ — ​ $ 16,630,087 ​ $ — ​ $ 16,630,087 Borrowings ​ 506,594 ​ — ​ 488,796 ​ — ​ 488,796 Accrued interest payable ​ 933 ​ — ​ 933 ​ — ​ 933 Derivatives: ​ ​ ​ ​ ​ Interest rate contracts ​ 49,051 ​ — ​ 49,051 ​ — ​ 49,051 Fair value hedges ​ 5,387 ​ — ​ 5,387 ​ — ​ 5,387 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Fair Value Measurements at December 31, 2020 using ​ ​ ​ ​ ​ Quoted Prices ​ Significant ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ in Active ​ Other ​ Significant ​ ​ ​ ​ ​ ​ ​ ​ Markets for ​ Observable ​ Unobservable ​ Total Fair ​ ​ ​ ​ ​ Identical Assets ​ Inputs ​ Inputs ​ Value ​ ​ Carrying ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Value ​ Level 1 ​ Level 2 ​ Level 3 ​ Balance ASSETS ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Cash and cash equivalents ​ $ 493,294 ​ $ 493,294 ​ $ — ​ $ — ​ $ 493,294 AFS securities ​ 2,540,419 ​ — ​ 2,540,419 ​ — ​ 2,540,419 HTM securities ​ 544,851 ​ — ​ 606,496 ​ 13,269 ​ 619,765 Restricted stock ​ 94,782 ​ — ​ 94,782 ​ — ​ 94,782 LHFS ​ ​ 96,742 ​ ​ — ​ 96,742 ​ — ​ ​ 96,742 Net loans ​ 13,860,774 ​ — ​ — ​ 13,710,640 ​ 13,710,640 Derivatives: ​ ​ ​ ​ ​ Interest rate contracts ​ 163,360 ​ — ​ 163,360 ​ — ​ 163,360 Accrued interest receivable ​ 75,757 ​ — ​ 75,757 ​ — ​ 75,757 BOLI ​ 326,892 ​ — ​ 326,892 ​ — ​ 326,892 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ LIABILITIES ​ ​ ​ ​ ​ Deposits ​ $ 15,722,765 ​ $ — ​ $ 15,763,991 ​ $ — ​ $ 15,763,991 Borrowings ​ 840,717 ​ — ​ 821,516 ​ — ​ 821,516 Accrued interest payable ​ 2,516 ​ — ​ 2,516 ​ — ​ 2,516 Derivatives: ​ ​ ​ ​ ​ Interest rate contracts ​ 163,360 ​ — ​ 163,360 ​ — ​ 163,360 Fair value hedges ​ 12,483 ​ — ​ 12,483 ​ — ​ 12,483 ​ The Company assumes interest rate risk (the risk that general interest rate levels will change) as a result of its normal operations. As a result, the fair values of the Company’s financial instruments will change when interest rate levels change and that change may be either favorable or unfavorable to the Company. Management attempts to match maturities of assets and liabilities to the extent believed necessary to minimize interest rate risk. Borrowers with fixed rate obligations, however, are less likely to prepay in a rising rate environment and more likely to prepay in a falling rate environment. Conversely, depositors who are receiving fixed rates are more likely to withdraw funds before maturity in a rising rate environment and less likely to do so in a falling rate environment. Management monitors rates and maturities of assets and liabilities and attempts to minimize interest rate risk by adjusting terms of new loans and deposits and by investing in securities with terms that mitigate the Company’s overall interest rate risk.

Revenue from Contract with Customer [Abstract]
REVENUE	15. REVENUE The majority of the Company’s noninterest income comes from short term contracts associated with fees for services provided on deposit accounts, credit cards, and wealth management accounts and is being accounted for in accordance with Topic 606. Typically, the duration of a contract does not extend beyond the services performed; therefore, the Company concluded that discussion regarding contract balances is immaterial. The Company’s performance obligations on revenue from interchange fees and deposit accounts are generally satisfied immediately, when the transaction occurs, or by month-end. Performance obligations on revenue from fiduciary and asset management fees are generally satisfied monthly or quarterly. For a majority of fee income on deposit accounts the Company is a principal, controlling the promised good or service before transferring it to the customer. For the majority of income related to wealth management income, the Company is an agent, responsible for arranging for the provision of goods and services by another party. Mortgage banking income is earned when the originated loans are sold to an investor on the secondary market. The loans are classified as LHFS prior to being sold. Additionally, the changes in fair value of the LHFS, loan commitments, and related derivatives are included in mortgage banking income. Noninterest income disaggregated by major source for the years ended December 31, 2021, 2020, and 2019 consisted of the following (dollars in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ 2021 ​ 2020 ​ 2019 Noninterest income: ​ ​ ​ Deposit Service Charges (1) ​ ​ ​ Overdraft fees ​ $ 17,126 ​ $ 17,792 ​ $ 24,092 Maintenance fees & other ​ 9,996 ​ 7,459 ​ 6,110 Other service charges, commissions, and fees (1) ​ 6,595 ​ 6,292 ​ 6,423 Interchange fees (1) ​ 8,279 ​ 7,184 ​ 14,619 Fiduciary and asset management fees (1) ​ ​ ​ ​ ​ Trust asset management fees ​ 12,571 ​ 10,804 ​ 9,141 Registered advisor management fees ​ 9,856 ​ 8,657 ​ 10,107 Brokerage management fees ​ 5,135 ​ 4,189 ​ 4,117 Mortgage banking income ​ 21,022 ​ 25,857 ​ 10,303 Gains on securities transactions ​ 87 ​ 12,294 ​ 7,675 Bank owned life insurance income ​ 11,488 ​ 9,554 ​ 8,311 Loan-related interest rate swap fees ​ 5,620 ​ 15,306 ​ 14,126 Other operating income (2)(3)(4) ​ 18,031 ​ 6,098 ​ 17,791 Total noninterest income ​ $ 125,806 ​ $ 131,486 ​ $ 132,815 (1) Income within scope of Topic 606.

EMPLOYEE BENEFITS AND STOCK BASED COMPENSATION	16. EMPLOYEE BENEFITS AND STOCK BASED COMPENSATION The Company has a 401(k) Plan designed to qualify under Section 401 of the Code that allows employees to defer a portion of their salary compensation as savings for retirement. The 401(k) Plan provides for the Company to match employee contributions based on each employee’s elected contribution percentage. For each employee’s 1% through 3% dollar contributions, the Company will match 100% of such dollar contributions, and for each employee’s 4% through 5% dollar contributions, the Company will match 50% of such dollar contributions. All employees are eligible to participate in the 401(k) Plan after meeting minimum age and service requirements. The Company also has an ESOP. All employees of the Company meeting minimum age and service requirements are eligible to participate in the ESOP plan. The Company makes discretionary profit-sharing contributions into the 401(k) Plan, ESOP, and in cash bonus payments. Company discretionary contributions to both the 401(k) Plan and the ESOP are allocated to participant accounts in proportion to each participant’s compensation and vest according to the respective plan’s vesting schedule. Employee contributions to the ESOP are not allowed. The 2019 information presented includes discontinued operations. Refer to Note 1 “Summary of Significant Accounting Policies” in this Form 10-K for further discussion regarding discontinued operations.

Under these deferred compensation plans, the Company had an obligation of $17.5 million at December 31, 2021 and $15.8 million at December 31, 2020. The Company owns life insurance policies on plan beneficiaries as an informal funding vehicle to meet future benefit obligations. The Atlantic Union Bankshares Corporation Stock and Incentive Plan (the “Plan”) was amended and restated by the Board of Directors of the Company on February 23, 2021, which amendment and restatement became effective on May 4, 2021 when approved by shareholders of the Company. The Plan was originally adopted by the Board as the Union First Market Bankshares Corporation 2011 Stock Incentive Plan (the “2011 Plan”) on November 2, 2010, and became effective on January 1, 2011, subject to the approval by the Company’s shareholders, which was obtained on April 26, 2011. The 2011 Plan was amended and restated as the Union Bankshares Corporation Stock and Incentive Plan (the “2015 Plan”) by the Board on January 29, 2015, which amendment and restatement became effective on April 21, 2015 when approved by shareholders of the Company. The 2015 Plan amended the 2011 Plan to, among other things, increase the maximum number of shares of the Company’s common stock issuable under the plan from 1,000,000 to 2,500,000 and add non-employee directors of the Company and certain subsidiaries, as well as regional advisory boards, as potential participants in the plan. The 2015 Plan was further amended by the Board effective May 20, 2019 to reflect the new name of the Company. The 2021 amendment and restatement amended and restated the 2015 Plan to, among other things, increase the maximum number of shares of the Company’s common stock issuable under the plan from 2,500,000 to 4,000,000. The Company may grant awards under the Plan until May 3, 2031. As of December 31, 2021, there were 1,855,601 shares available for future issuance in the Plan. ​ The Plan provides for the granting of stock-based awards to key employees and non-employee directors of the Company and its subsidiaries in the form of: (i) stock options; (ii) RSAs, (iii) RSUs, (iv) stock awards; (v) PSUs; and performance cash awards. The Company issues new shares to satisfy stock-based awards. For option awards, the option price cannot be less than the fair market value of the stock on the grant date. Stock option awards have a maximum term of ten years from the date of grant, and generally become exercisable over a 5 year period beginning on the first anniversary of the date of grant. No stock options have been granted since February 2012. In 2019 the Company assumed additional stock options with the acquisition of Access. The stock option awards have a maximum term of five years from the date of grant, and generally become exercisable over a 4 year period beginning on the first anniversary of the date of grant.

SUMMARY OF SIGNIFICANT ACCOUN_2

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	12 Months Ended
	Dec. 31, 2021
The Company	The Company Effective October 1, 2021, Old Dominion Capital Management, Inc., and its subsidiary, Outfitter Advisors, Ltd., merged with and into DHFB, as part of an internal reorganization to streamline operations. Old Dominion Capital Management now operates as a division of DHFB. Effective March 1, 2021, Middleburg Financial, the Bank’s wealth management division was rebranded to Atlantic Union Bank Wealth Management, and Middleburg Investment Services, LLC changed its name to Atlantic Union Financial Consultants, LLC. Effective May 17, 2019, Union Bankshares Corporation changed its name to Atlantic Union Bankshares Corporation and Union Bank & Trust changed its name to Atlantic Union Bank.
Basis of Financial Information	Basis of Financial Information The preparation of the consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from these estimates. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the ALLL, acquired loans, the valuation of goodwill, deferred tax assets and liabilities, and the fair value of financial instruments.
Principles of Consolidation	Principles of Consolidation – The accompanying consolidated financial statements include financial information related to Atlantic Union Bankshares Corporation and its majority-owned subsidiaries and those variable interest entities where the Company is the primary beneficiary, if any. In preparing the consolidated financial statements, all significant inter-company accounts and transactions have been eliminated. Assets held in an agency or fiduciary capacity are not included in the consolidated financial statements. Accounting guidance states that if a business enterprise is the primary beneficiary of a variable interest entity, the assets, liabilities, and results of the activities of the variable interest entity should be included in the consolidated financial statements of the business enterprise. An entity is deemed to be the primary beneficiary of a variable interest entity if that entity has both the power to direct the activities that most significantly impact its economic performance; and the obligation to absorb losses or the right to receive benefits that could potentially be significant to the variable interest entity .
Segment Reporting	Segment Reporting On May 30, 2019, the Bank notified TFSB that the Bank was terminating its primary agreement with TFSB and will no longer allow TFSB to offer residential mortgages from Bank locations. UMG operations remain discontinued, although the Company continues to offer residential mortgages through a division of the Bank. As of December 31, 2021 and 2020, the assets and liabilities, as well as the operating results, of the discontinued mortgage segment were not considered material. Management believes there are no material on-going obligations with respect to UMG’s business that have not been recorded or disclosed in the Company’s consolidated financial statements.
Cash and Cash Equivalents	Cash and Cash Equivalents - Restricted cash is disclosed in Note 10 “Commitments and Contingencies” 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 on 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.
Investment Securities	Investment Securities Available for Sale Held to Maturity - debt securities that the Company has the positive intent and ability to hold to maturity are classified as HTM. HTM securities are reported at carrying value. Transfers of debt securities into the HTM category from the AFS category are made at fair value at the date of transfer. The unrealized holding gain or loss at the date of transfer is retained in OCI and in the carrying value of the HTM securities. Such amounts are amortized over the remaining life of the security. Equity Investments significant influence are accounted for using the cost method of accounting. Under the cost method, investments are carried at cost and are adjusted only for other-than-temporary declines in fair value, certain distributions, and additional investments. Equity investments in unconsolidated entities with a readily determinable fair value that are not accounted for under the equity method will be measured at fair value through net income. Restricted Stock, at cost Interest income includes amortization of purchase premium or discount. Premiums and discounts on securities are generally amortized on the level-yield method without anticipating prepayments, except for MBS where prepayments are anticipated. Premiums on callable debt securities are amortized to their earliest call date. Discounts on callable debt securities are amortized to their maturity date. Gains and losses on sales are recorded on the trade date and determined using the specific identification method. The Company regularly evaluates AFS securities whose values have declined below amortized cost to assess whether the decline in fair value is the result of credit impairment. For AFS securities, the Company evaluates the fair value and credit quality of its AFS securities on at least a quarterly basis. In the event the fair value of a security falls below its amortized cost basis, the security will be evaluated to determine whether the decline in value was caused by changes in market interest rates or security credit quality. The primary indicators of credit quality for the Company’s AFS portfolio are security type and credit rating, which are influenced by a number of security-specific factors that may include obligor cash flow, geography, seniority, structure, credit enhancement and other factors. There is currently no ACL held against the Company’s AFS securities portfolio at December 31, 2021, consistent with December 31, 2020. See Note 3 “Securities,” for additional information on the Company’s ACL analysis. If unrealized losses are related to credit quality, the Company estimates the credit related loss by evaluating the present value of cash flows expected to be collected from the security with the amortized cost basis of the security. If the present value of cash flows expected to be collected is less than the amortized cost basis of the security and a credit loss exists, an ACL shall be recorded for the credit loss, limited by the amount that the fair value is less than amortized cost basis. Non-credit related declines in fair value are recognized in OCI, net of applicable taxes. Changes in the ACL are recorded as a provision for or reversal of credit loss expense. Charge-offs are recorded against the ACL when management believes the AFS security is no longer collectible. A debt security is placed on nonaccrual status at the time any principal or interest payments become 90 days delinquent. The Company evaluates the credit risk of its HTM securities on at least a quarterly basis. Management estimates expected credit losses on held-to-maturity debt securities based on an individual basis based on the PD/LGD methodology primarily using security-level credit ratings. Management has an immaterial ACL on HTM securities at December 31, 2021 and 2020. ​
Loans Held for Sale	Loans Held for Sale
Loans Held for Investment	Loans Held for Investment Loans that management has the intent and ability to hold for the foreseeable future or until maturity or pay-off generally are reported at their outstanding unpaid principal balances adjusted for any charge-offs, the ALLL, and any deferred fees and costs on originated loans. Interest income is accrued on the unpaid principal balance. Loan origination fees, net of certain direct origination costs, are deferred and recognized as an adjustment of the related loan yield using the interest method. Below is a summary of the current loan portfolios: Construction and Land Development Also, included in this category are loans generally made to residential home builders to support their lot and home construction inventory needs. Repayment relies upon the sale of the underlying residential real estate project. This type of lending carries a higher level of risk as compared to other commercial lending. This class of lending manages risks related to residential real estate market conditions, a functioning primary and secondary market in which to finance the sale of residential properties, and the borrower’s ability to manage inventory and run projects. The Company manages this risk by lending to experienced builders and developers by using specific underwriting policies and procedures for these types of loans and by avoiding excessive concentrations with any particular customer or geographic region. Commercial Real Estate – Owner Occupied Commercial Real Estate – Non-Owner Occupied Multifamily Real Estate Commercial & Industrial Residential 1-4 Family - Commercial Residential 1-4 Family - Consumer Residential 1-4 Family - Revolving Auto Consumer Other Commercial - portfolios carry risks associated with the creditworthiness of the borrower and changes in the economic environment. The Company manages these risks by using general underwriting policies and procedures for these types of loans and experienced underwriting. Loans that support small business lines of credit and agricultural lending are included in this category; however, neither are a material source of business for the Company. Nonaccruals, Past Dues, and Charge-offs The policy for placing commercial and consumer loans on nonaccrual status is generally when the loan is 90 days delinquent unless the credit is well secured and in process of collection. Consumer loans are typically charged-off when management judges the loan to be uncollectible but generally no later than 120 days past due for non-real estate secured loans and 180 days for real estate secured loans. Non-real estate secured consumer loans are generally not placed on nonaccrual status prior to charge off. Commercial loans are typically written down to net realizable value when it is determined that the Company will be unable to collect the principal amount in full and the amount is a confirmed loss. Loans in all classes of portfolios are considered past due or delinquent when a contractual payment has not been satisfied. Loans are placed on nonaccrual status or charged off at an earlier date if collection of principal and interest is considered doubtful and in accordance with regulatory requirements. In response to the COVID-19 pandemic, the Company offered short-term loan modifications to assist borrowers. The Company enhanced the monitoring over loans that received modifications, specifically full principal and interest payment deferrals, and considered nonaccrual treatment at which time the Company no longer expected to collect all principal and interest over the life of the loan. The process for charge-offs is discussed in detail within the “Allowance for Loan and Lease Losses” section of this Note 1. For both the commercial and consumer loan segments, all interest accrued but not collected for loans placed on nonaccrual status or charged-off is reversed against interest income and accrual of interest income is terminated. Payments and interest on these loans are accounted for using the cost-recovery method by applying all payments received as a reduction to the outstanding principal balance until qualifying for return to accrual. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured. The determination of future payments being reasonably assured varies depending on the circumstances present with the loan; however, the timely payment of contractual amounts owed for six consecutive months is a primary indicator. The authority to move loans into or out of accrual status is limited to senior Special Assets Officers and the Chief Credit Officer, though reclassification of certain loans may require approval of the Special Assets Loan Committee.
Allowance for Loan and Lease Losses	Allowance for Loan and Lease Losses - valuation account that is deducted from the loans' amortized cost basis to present the net amount expected to be collected on the loans. Loans are charged off against the ALLL when management believes the loan balance is no longer collectible. Subsequent recoveries of previously charged off amounts are recorded as increases to the ALLL; however, expected recoveries do not exceed the aggregate of amounts previously charged-off. Management’s determination of the adequacy of the ALLL is based on an evaluation of the composition of the loan portfolio, the value and adequacy of collateral, current economic conditions, historical loan loss experience, reasonable and supportable forecasts, and other risk factors. The ALLL is estimated using a loan-level PD/LGD method for all loans with the exception of its overdraft, auto and third party consumer lending portfolios. For auto and third party consumer lending portfolios, the Company has elected to pool those loans based on similar risk characteristics to determine the ALLL using vintage and loss rate methods. The Company considers a number of economic variables in developing the ALLL of which the Virginia unemployment rate is the most significant. The ALLL quantitative estimate is sensitive to changes in the forecast of the Virginia unemployment rate over the two-year reasonable and supportable period, with the commercial portfolio being the most sensitive to fluctuations in unemployment. To forecast Virginia unemployment, the Company utilizes Moody’s economic forecasts. At December 31, 2021, the baseline scenario used in the two-year reasonable and supportable period forecast included the Virginia unemployment rate at an average of 2.6%, compared to an average of 5.0% Virginia unemployment rate in the baseline scenario forecast used for the December 31, 2020 estimate. Because current economic conditions and forecasts can change and future events are inherently difficult to predict, the anticipated amount of estimated credit losses on loans, and therefore the appropriateness of the ALLL, could change significantly. It is difficult to estimate how potential changes in any one economic factor or input might affect the overall allowance because a wide variety of factors and inputs are considered in estimating the allowance and changes in those factors and inputs considered may not occur at the same rate and may not be consistent across all loan types. Additionally, changes in factors and inputs may be directionally inconsistent, such that improvement in one factor may offset deterioration in others. While management uses available information to estimate expected losses on loans, future changes in the ALLL may be necessary based on changes in portfolio composition, portfolio credit quality, and/or economic conditions. Determining the Contractual Term Expected credit losses are estimated over the contractual term of the loans, adjusted for expected prepayments when appropriate. The contractual term excludes expected extensions, renewals, and modifications unless either of the following applies: management has a reasonable expectation at the reporting date that a TDR will be executed with an individual borrower or the extensions or renewal options are included in the original or modified contract at the reporting date and are not unconditionally legally cancelable by the Company. The Company’s ALLL measures the expected lifetime loss using pooled assumptions and loan-level details for financial assets that share common risk characteristics and evaluates an individual reserve in instances where the financial assets do not share the same risk characteristics. Collectively Assessed Reserve Consideration Loans that share common risk characteristics are considered collectively assessed. Loss estimates within the collectively assessed population are based on a combination of pooled assumptions and loan-level characteristics. Quantitative loss estimation models have been developed based largely on internal historical data at the loan and portfolio levels from 2005 through the current period and the economic conditions during the same time period. Expected losses for the Company’s collectively assessed loan segments are estimated using a number of quantitative methods including PD/LGD, Vintage, and Loss Rate. As part of its qualitative framework, the Company evaluates its current underwriting standards, geographic footprint, national and international current and forecasted economic conditions, expected government stimulus, and other factors to estimate the impact that changes in these factors may have on expected loan losses. The Company’s ALLL for the current period is based on a two-year reasonable and supportable forecast period with a straight-line reversion over the next two years to long-term average loss factors. Individually Assessed Reserve Consideration Loans that do not share risk characteristics are evaluated on an individual basis. The individual reserve component relates to loans that have shown substantial credit deterioration as measured by risk rating and/or delinquency status. In addition, the Company has elected the practical expedient that would include loans for individual assessment consideration if the repayment of the loan is expected substantially through the operation or sale of collateral because the borrower is experiencing financial difficulty. Where the source of repayment is the sale of collateral, the ALLL is based on the fair value of the underlying collateral, less selling costs, compared to the amortized cost basis of the loan. If the ALLL is based on the operation of the collateral, the reserve is calculated based on the fair value of the collateral calculated as the present value of expected cash flows from the operation of the collateral, compared to the amortized cost basis. If the Company determines that the value of a collateral dependent loan is less than the recorded investment in the loan, the Company charges off the deficiency if it is determined that such amount is deemed uncollectible. Typically, a loss is confirmed when the Company is moving toward foreclosure or final disposition. The Company obtains appraisals from a pre-approved list of independent, third party appraisers located in the market in which the collateral is located. The Company’s approved appraiser list is continuously maintained by the Company’s REVG to ensure the list only includes such appraisers that have the experience, reputation, character, and knowledge of the respective real estate market. At a minimum, it is ascertained that the appraiser is currently licensed in the state in which the property is located, experienced in the appraisal of properties similar to the property being appraised, has knowledge of current real estate market conditions and financing trends, and is reputable. The Company’s internal REVG, which reports to the Enterprise Risk Management group, performs either a technical or administrative review of all appraisals obtained in accordance with the Company’s Appraisal Policy. The Appraisal Policy mirrors the Federal regulations governing appraisals, specifically the Interagency Appraisal and Evaluation Guidelines and FIRREA. A technical review will ensure the overall quality of the appraisal, while an administrative review ensures that all of the required components of an appraisal are present. Independent appraisals or valuations are obtained on all individually assessed loans, as well as updated every twelve months for all individually assessed loans. Adjustments to real estate appraised values are only permitted to be made by the REVG. The individually assessed analysis is reviewed and approved by senior Credit Administration officers and the Special Assets Loan Committee. External valuation sources are the primary source to value collateral dependent loans; however, the Company may also utilize values obtained through other valuation sources. These alternative sources of value are used only if deemed to be more representative of value based on updated information regarding collateral resolution. The ALLL on loans individually assessed is updated, reviewed, and approved on a quarterly basis at or near the end of each reporting period. The Company performs regular credit reviews of the loan portfolio to review the credit quality and adherence to its underwriting standards. The credit reviews include annual commercial loan reviews performed by the Company’s commercial bankers in accordance with CLP, relationship reviews that accompany annual loan renewals, and independent reviews by its Loan Review Group. Upon origination, each commercial loan is assigned a risk rating ranging from one to nine, with loans closer to one having less risk. This risk rating scale is the Company’s primary credit quality indicator. Consumer loans are not risk rated unless past due status, bankruptcy, or other event results in the assignment of a Substandard or worse risk rating in accordance with the consumer loan policy. Governance The Company’s Allowance Committee, which reports to the Audit Committee and contains representatives from both the Company’s finance and risk teams, is responsible for approving the Company’s estimate of expected credit losses and resulting ALLL. The Allowance Committee considers the quantitative model results and qualitative factors when approving the final ALLL. The Company’s ALLL model is subject to the Company’s models risk management program which is overseen by the Model Risk Management Committee which reports to the Company’s Board Risk Committee. Allowance for loan and lease losses – prior to the adoption of ASC 326 A loan was considered impaired when, based on current information and events, it was probable that the Company will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement. Factors considered in determining impairment include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due. Loans that experienced insignificant payment delays and payment shortfalls generally were not classified as impaired. Management determined the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record, and the amount of the shortfall in relation to the principal and interest owed. Impairment was measured on a loan-by-loan basis by either the present value of expected future cash flows discounted at the loan’s effective interest rate, the loan’s obtainable market price, or the fair value of the collateral. The impairment loan policy was the same for all segments within the commercial loan segment. For the consumer loan segment, large groups of smaller balance homogeneous loans were collectively evaluated for impairment. This evaluation subjected each of the Company’s homogenous pools to a historical loss factor derived from net charge-offs experienced over the preceding 24 quarters. The Company applied payments received on impaired loans to principal and interest based on the contractual terms until they were placed on nonaccrual status. All payments received were then applied to reduce the principal balance and recognition of interest income is terminated as previously discussed. The Company’s ALL consisted of specific, general, and qualitative components. The specific reserve component related to impaired loans. Upon being identified as impaired, for loans not considered to be collateral-dependent, an ALL was established when the discounted cash flows of the impaired loan was lower than the carrying value of that loan. The impairment of significant collateral-dependent loans was measured based on the fair value of the underlying collateral, less selling costs, compared to the carrying value of the loan. If the Company determined that the value of an impaired collateral dependent loan was less than the recorded investment in the loan, the Company charged off the deficiency if it was determined that such amount represented a confirmed loss. Typically, a loss was confirmed when the Company was moving towards foreclosure or final disposition. The general reserve component covered non-impaired loans and was quantitatively derived from an estimate of credit losses adjusted for various qualitative factors applicable to both commercial and consumer loan segments. The estimate of credit losses was a function of the net charge-off historical loss experience to the average loan balance of the portfolio averaged during a period that management had determined to adequately reflect the losses inherent in the loan portfolio. The Company had implemented a rolling 24-quarter look back period, which was re-evaluated on a periodic basis to ensure the reasonableness of the period being used. The qualitative component included adjustments for current portfolio specific credit risks and local and national economic trends. Acquired loans were recorded at their fair value at acquisition date without carryover of the acquiree’s previously established ALL, as credit discounts were included in the determination of fair value. The fair value of the loans were determined using market participant assumptions in estimating the amount and timing of both principal and interest cash flows expected to be collected on the loans and then applying a market-based discount rate to those cash flows. During evaluation upon acquisition, acquired loans were also classified as either acquired impaired (or PCI) or acquired performing. Acquired performing loans were accounted for under ASC 310-20, Receivables – Nonrefundable Fees and Other Costs. The difference between the fair value and unpaid principal balance of the loan at acquisition date (premium or discount) was amortized or accreted into interest income over the life of the loans. If the acquired performing loan has revolving privileges, it was accounted for using the straight-line method; otherwise, the effective interest method is used. Acquired impaired loans reflected credit quality deterioration since origination, as it was probable at acquisition that the Company would not be able to collect all contractually required payments. These PCI loans were accounted for under ASC 310-30, Receivables – Loans and Debt Securities Acquired with Deteriorated Credit Quality. The PCI loans were segregated into pools based on loan type and credit risk. Loan type was determined based on collateral type, purpose, and lien position. Credit risk characteristics included risk rating groups, nonaccrual status, and past due status. For valuation purposes, these pools were further disaggregated by maturity, pricing characteristics, and re-payment structure. PCI loans were written down at acquisition to fair value using an estimate of cash flows deemed to be collectible. Accordingly, such loans were no longer classified as nonaccrual even though they may be contractually past due because the Company expected to fully collect the new carrying values of such loans, which is the new cost basis arising from purchase accounting. Quarterly, management performed a recast of PCI loans based on updated future expected cash flows, which was updated through reassessment of default rates, loss severity, and prepayment speed assumptions. The excess of the cash flows expected to be collected over a pool’s carrying value was considered to be the accretable yield and was recognized as interest income over the estimated life of the loan or pool using the effective yield method. The excess of the undiscounted contractual balances due over the cash flows expected to be collected was considered to be the nonaccretable difference, which represented the estimate of credit losses expected to occur and was considered in determining the fair value of loan at the acquisition date. Any subsequent increases in expected cash flows over those expected at the acquisition date in excess of fair value were adjusted through an increase in the accretable yield on a prospective basis; any decreases in expected cash flows attributable to credit deterioration are recognized by recording a provision for loan losses. The PCI loans were subject to the Company’s internal and external credit review and monitoring. If further credit deterioration was experienced, such deterioration was measured and the provision for loan losses was increased. A loan was removed from the pool (at its carrying value) if the loan was sold, foreclosed, or assets were received in full satisfaction of the loan.
Acquired Loans	Acquired Loans – The Company has purchased loans, some of which have experienced more than insignificant credit deterioration since origination. Acquired loans are recorded at their fair value at acquisition date without carryover of the acquiree’s previously established ALLL, as credit discounts are included in the determination of fair value. The fair value of the loans is determined using market participant assumptions in estimating the amount and timing of both principal and interest cash flows expected to be collected on the loans and then applying a market-based discount rate to those cash flows. During evaluation upon acquisition, acquired loans are also classified as either or PCD or acquired performing. The acquired loans are subject to the Company’s ALLL Policy upon acquisition. Acquired performing loans are accounted for under ASC 310-20, Receivables – Nonrefundable Fees and Other Costs PCD loans reflect loans that have experienced more-than-insignificant credit deterioration since origination, as it is probable at acquisition that the Company will not be able to collect all contractually required payments. These PCD loans are accounted for under ASC 326 . The PCD loans are segregated into pools based on loan type and credit risk. Loan type is determined based on collateral type, purpose, and lien position. Credit risk characteristics include risk rating groups, nonaccrual status, and past due status. For valuation purposes, these pools are further disaggregated by maturity, pricing characteristics, and re-payment structure. ​ PCD loans are recorded at the amount paid. An ALLL is determined using the same methodology as other loans held for investment. The initial ALLL is determined on a collective basis and is allocated to individual loans. The sum of the loan's purchase price and ALLL becomes its initial amortized cost basis. The difference between the initial amortized cost basis and the par value of the loan is a noncredit discount or premium, which is amortized into interest income over the life of the loan. Subsequent changes to the ALLL are recorded through provision expense.
Troubled Debt Restructurings	Troubled Debt Restructurings - The Company reviews previously restructured loans quarterly in order to determine whether any have performed, subsequent to the restructure, at a level that would allow for them to be removed from reportable TDR status. The Company generally would consider a change in this classification if the borrower is no longer experiencing financial difficulty, the loan is current or less than 30 days past due at the time the status change is being considered, and the loan has performed under the restructured terms for a consecutive twelve-month period. A loan may also be considered for removal from TDR status as a result of a subsequent restructure under certain restrictive circumstances. The removal of TDR designations must be approved by the Company's Special Asset Loan Committee. Loan modifications made under the Joint Guidance and CARES Act, as amended by the CAA, were suspended from TDR evaluation.

Goodwill and Intangible Assets	Goodwill and Intangible Assets - Goodwill and Other Intangible Assets, Intangible assets with definite useful lives are amortized over their estimated useful lives, which range from 4 to 10 years, to their estimated residual values. Long-lived assets, including purchased intangible assets subject to amortization, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to estimated undiscounted future cash flows expected to be generated by the asset. If the carrying amount of an asset exceeds its estimated future cash flows, an impairment charge is recognized in the amount by which the carrying amount of the asset exceeds the fair value of the asset. Assets to be disposed of would be separately presented on the Company’s Consolidated Balance Sheets and reported at the lower of the carrying amount or fair value less costs to sell, would no longer depreciated. Management concluded that no circumstances indicating an impairment of these assets existed as of the balance sheet date. The Company performs the analysis annually on April 30 of each year at the reporting unit level whereby the Company compares the estimated fair value of the reporting unit to its carrying value. If the estimated fair value of a reporting unit exceeds its carrying value, goodwill is not considered impaired. The Company engaged a third-party valuation specialist to assist management in performing its annual goodwill impairment analysis. The last goodwill impairment analysis was conducted on April 30, 2021. To determine the fair value of a reporting unit, the Company utilizes a combination of two separate quantitative methods, the market value approach, which considers comparable publicly-traded companies, and the income approach which estimates future cash flows. Critical assumptions that are used as part of these calculations include: the selection of comparable publicly-traded companies and selection of market comparable acquisition transactions. In addition, other key assumptions include the discount rate, the forecast of future earnings and cash flows of the reporting unit, economic conditions, which impact the assumptions related to interest and growth rates, and loss rates, the cost savings expected to be realized by a market participant, the control premium associated with the reporting unit and a relative weight given to the valuations derived by the two valuation methods. At April 30, 2021, the Company determined that there was no impairment to its goodwill. The Company performed a sensitivity analysis on key assumptions and concluded that no impairment existed as of the balance sheet date.

Derivatives	Derivatives During the normal course of business, the Company enters into commitments to originate mortgage loans whereby the interest rate on the loan is determined prior to funding (“rate lock commitments”). For commitments issued in connection with potential loans intended for sale, the Bank enters into positions of forward month MBS to be announced (“TBA”) contracts on a mandatory basis or on a one-to-one forward sales contract on a best efforts basis. The Company enters into TBA contracts in order to control interest rate risk during the period between the rate lock commitment and mandatory sale of the mortgage loan. Both the rate lock commitment and the forward TBA contract are considered to be derivatives. A mortgage loan sold on a best efforts basis is locked into a forward sales contract with a counterparty on the same day as the rate lock commitment to control interest rate risk during the period between the commitment and the sale of the mortgage loan. Both the rate lock commitment and the forward sales contract are considered to be derivatives. Mortgage banking derivatives as of December 31, 2021 and 2020 did not have a material impact on the Company’s Consolidated Financial Statements. The market values of rate lock commitments and best efforts forward delivery commitments are not readily ascertainable with precision because they are not actively traded in stand-alone markets. The Company determines the fair value of rate lock commitments, delivery contracts, and forward sales contracts of MBS by measuring the change in the value of the underlying asset, while taking into consideration the probability that the rate lock commitments will close or will be funded. Certain risks arise from the forward delivery contracts in that the counterparties to the contracts may not be able to meet the terms of the contracts. Additional risks inherent in mandatory delivery programs include the risk that, if the Company does not close the loans subject to rate lock commitments, it will still be obligated to deliver MBS to the counterparty under the forward sales agreement.
Affordable Housing Entities	Affordable Housing Entities - The Company invests in private investment funds that make equity investments in multifamily affordable housing properties that provide affordable housing and historic tax credits for these investments. The activities of these entities are financed with a combination of invested equity capital and debt. The Company accounts for its affordable housing entities using the proportional amortization method. Under the proportional amortization method, the Company amortizes the initial cost of the investment in proportion to the tax credits and other tax benefits received, and recognizes the net investment performance in the income statement as a component of income tax expense (benefit). For the years ended December 31, 2021 and 2020, the Company recognized amortization of $3.6 million and $3.0 million, respectively, and tax credits and tax savings of $4.3
Stock Compensation Plan	Stock Compensation Plan The Company’s outstanding stock options related to shares assumed with the acquisition of Access. For the options assumed, the fair value of the stock options was estimated based on the date of acquisition, using the Black-Scholes option valuation. The converted option price of the Company’s common stock at acquisition was used for determining the associated compensation expense for nonvested stock awards. The valuation was used in 2021, 2020, and 2019 to determine the valuation of the stock options. Key assumptions used in the valuation were dividend yield, expected life, expected volatility, and the risk free rate. For the years ended December 2021, 2020, and 2019, the fair value of PSUs are determined and fixed on the grant date based on the Company’s stock price, adjusted for the exclusion of dividend equivalents, and the Monte Carlo simulation valuation was used to determine the grant date fair value of PSUs granted. The fair value of RSAs and stock awards are based on the trading price of the Company’s stock on the date of the grant. ASC 718 requires the Company to estimate forfeitures when recognizing compensation expense and that this estimate of forfeitures be adjusted over the requisite service period or vesting schedule based on the extent to which actual forfeitures differ from such estimates. Changes in estimated forfeitures are recognized through a cumulative catch-up adjustment, which is recognized in the period of change, and also will affect the amount of estimated unamortized compensation expense to be recognized in future periods. For more information and tables refer to Note 16 “Employee Benefits and Stock Based Compensation.”
Income Taxes	Income Taxes When tax returns are filed, it is highly certain that some positions taken would be sustained upon examination by the taxing authorities, while others are subject to uncertainty about the merits of the position taken or the amount of the position that would be ultimately sustained. The benefit of a tax position is recognized in the financial statements in the period during which, based on all available evidence, management believes it is more likely than not that the position will be sustained upon examination, including the resolution of appeals or litigation processes, if any. Tax positions taken are not offset or aggregated with other positions. Tax positions that meet the more-likely-than-not recognition threshold are measured as the largest amount of tax benefit that is more than 50% likely to be realized upon settlement with the applicable taxing authority. The portion of the benefits associated with tax positions taken that exceeds the amount measured as described above is reflected as a liability for unrecognized tax benefits on the Company’s Consolidated Balance Sheets along with any associated interest and penalties that would be payable to the taxing authorities upon examination. Interest and penalties associated with unrecognized tax benefits are classified as additional income taxes on the Company’s Consolidated Statements of Income. The Company did not record any material interest or penalties for the periods ending December 31, 2021, 2020, or 2019 related to tax positions taken. As of December 31, 2021 and 2020, there were no accruals for uncertain tax positions. The Company and its wholly-owned subsidiaries file a consolidated income tax return. Each entity provides for income taxes based on its contribution to income or loss of the consolidated group.

Fair Value	Fair Value ASC 820 specifies a hierarchy of valuation techniques based on whether the inputs to those valuation techniques are observable or unobservable. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect the Company’s market assumptions. The three levels of the fair value hierarchy under ASC 820 based on these two types of inputs are as follows: Level 1 valuation is based on quoted prices in active markets for identical assets and liabilities; Level 2 valuation is based on observable inputs including quoted prices in active markets for similar assets and liabilities, quoted prices for identical or similar assets and liabilities in less active markets, and model-based valuation techniques for which significant assumptions can be derived primarily from or corroborated by observable data in the markets; and Level 3 valuation is based on model-based techniques that use one or more significant inputs or assumptions that are unobservable in the market. These unobservable inputs reflect the Company’s assumptions about what market participants would use and information that is reasonably available under the circumstances without undue cost and effort. For more specific information on the valuation techniques used by the Company to measure certain financial assets and liabilities recorded at fair value in the financial statements refer to Note 14 “Fair Value Measurements.”

The PPP loan funding program expired on May 31, 2021. The Company had PPP loans with a recorded investment of million as of December 31, 2021 and 2020, respectively. The loans carry a 1% interest rate.
Adoption of New Accounting Standards	Adoption of New Accounting Standards On January 1, 2021, the Company adopted Topic 740. This guidance was issued to simplify accounting for income taxes by removing specific technical exceptions that often produce information difficult for users of financial statements to understand. The amendments also improve consistent application of and simplify GAAP for other areas of Topic 740 by clarifying and amending existing guidance. The Company’s adoption of Topic 740 did not have a material impact on the consolidated financial statements. On January 1, 2020, the Company adopted ASC 326. This ASU updates the existing guidance to provide financial statement users with more decision-useful information about the expected credit losses on financial instruments and other commitments to extend credit held by a reporting entity at each reporting date. This ASU replaces the incurred loss impairment methodology in current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. The measurement of expected credit losses under the CECL methodology is applicable to financial assets measured at amortized cost, including loan receivables and HTM debt securities. It also applies to unfunded credit exposures not accounted for as insurance (loan commitments, letters of credit, financial guarantees, and other similar instruments). The Company established a cross-functional governance structure to oversee the Company’s implementation of the CECL methodology, which included evaluating key assumptions used and assessing the internal controls over financial reporting related to the adoption of ASC 326. The Company adopted ASC 326 using the modified retrospective method for all financial assets measured at amortized cost and unfunded credit exposures. Results for reporting periods beginning after January 1, 2020 are presented under ASC 326, while prior period amounts continue to be reported in accordance with previously applicable GAAP. As a result of adopting ASC 326, the Company recorded a net decrease to retained earnings of $39.1 million. ASC 326 also replaced the Company’s current accounting for PCI loans. With the adoption of ASC 326, previously classified PCI loans are now classified as PCD loans. In accordance with ASC 326, the Company did not re-assess whether individual modifications were needed to individual acquired financial assets accounted for in the pools with TDRs as of the date of adoption. The Company adopted ASC 326 using the prospective transition approach for financial assets with PCD that were previously identified as PCI and accounted for under ASC 310-30. On January 1, 2020, the amortized cost basis of the PCD assets were adjusted to reflect the addition of $2.4 million to the ALLL. The remaining noncredit discount (based on the adjusted amortized cost basis) will be accreted into interest income at the effective interest rate as of January 1, The Company adopted ASC 326 using the prospective transition approach for debt securities. The effective interest rate on these debt securities was not changed. Upon adoption of ASC 326, the Company did not have any securities included in its portfolio where OTTI had previously been The following table illustrates the impact of ASC ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, ​ January 1, ​ January 1, ​ ​ 2019 ​ 2020 ​ 2020 ​ ​ As Previously Reported (Incurred Loss) ​ Impact of CECL Adoption ​ As Reported Under CECL Assets: ​ ​ ​ ​ ​ ​ Loans ​ ​ ​ ​ ​ ​ Commercial $ 30,941 $ 6,184 $ 37,125 Consumer ​ 11,353 ​ 41,300 ​ 52,653 Allowance for loan and lease losses ​ 42,294 ​ 47,484 ​ 89,778 Liabilities: ​ ​ ​ ​ ​ ​ Allowance for credit losses on unfunded credit exposure ​ 900 ​ 4,160 ​ 5,060 Total Allowance for credit losses $ 43,194 $ 51,644 $ 94,838
