Accounting Policies [Abstract]
Summary of Significant Accounting Policies	NOTE A—SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Nature of Operations: Operating Segments: Basis of Presentation: United determines whether it has a controlling financial interest in an entity by first evaluating whether the entity is a voting interest entity or a variable interest entity (“VIE”) under U.S. generally accepted accounting principles. Voting interest entities are entities in which the total equity investment at risk is sufficient to enable the entity to finance itself independently and provides the equity holders with the obligation to absorb losses, the right to receive residual returns and the right to make decisions about the entity’s activities. United consolidates voting interest entities in which it has all, or at least a majority of, the voting interest. As defined in applicable accounting standards, VIEs are entities that lack one or more of the characteristics of a voting interest entity. A controlling financial interest in a VIE is present when an enterprise has both the power to direct the activities of the VIE that most significantly impact the VIE’s economic performance and an obligation to absorb losses or the right to receive benefits that could potentially be significant to the VIE. The enterprise with a controlling financial interest, known as the primary beneficiary, consolidates the VIE. United’s wholly owned and indirect wholly owned statutory trust subsidiaries are VIEs for which United is not the primary beneficiary. Accordingly, its accounts are not included in United’s consolidated financial statements. The accounting and reporting policies of United conform with U.S. generally accepted accounting principles. In preparing the consolidated financial statements, management is required to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. To conform to the 2022 presentation, certain reclassifications have been made to prior period amounts, which had no impact on net income, comprehensive income or shareholders’ equity. In the opinion of management, all adjustments necessary for a fair presentation of financial position and results of operations have been made. Such adjustments are of a normal and recurring nature. In addition, $1,483,987,000 was reclassed from noninterest-bearing deposits to interest-bearing deposits on United’s Consolidated Balance Sheets for the period ended December 31, 2021 due to the nature of the underlying deposit accounts and a misclassification in the previous presentation. This reclassification did not impact any other amounts reported or disclosed in the consolidated financial statements. In the opinion of management, all adjustments necessary for a fair presentation of financial position and results of operations have been made. The Company has evaluated events and transactions subsequent to December 31, 2022 through the date these financial statements were issued. Based on definitions and requirements of generally accepted accounting principles for “Subsequent Events,” the Company has not identified any events that would require adjustments to, or disclosure in the financial statements. Cash and Cash Equivalents: Debt securities HTM securities are accounted for at amortized cost, but the Company must have both the positive intent and the ability to hold those securities to maturity. There are very limited circumstances under which securities in the HTM category can be sold without jeopardizing the cost basis of accounting for the remainder of the securities in this category. Substantially all of the Company’s HTM debt securities are issued by state and political subdivisions (municipalities). As of December 31, 2022, United considers its HTM debt securities portfolio to be immaterial. AFS securities are accounted for at fair value. Gains and losses realized on the sale of these securities are accounted for based on the specific identification method. Unrealized gains and losses for AFS securities are excluded from earnings and reported net of the related tax effect in the accumulated other comprehensive income component of shareholders’ equity. Allowance for Credit Losses (HTM Debt Securities) Allowance for Credit Losses (AFS Debt Securities) available-for-sale An entity may no longer consider the length of time fair value has been less than amortized cost. Changes in the allowance for credit losses are recorded as a provision (or release) for credit losses. Losses are charged against the allowance when management believes the uncollectibility of an AFS security is confirmed or when either of the criteria regarding intent or requirement to sell is met. As of December 31, 2022, the Company determined that the unrealized loss positions in AFS securities were not the result of credit losses, and therefore, an allowance for credit losses was not recorded. United has the intent and the ability to hold these securities until such time as the value recovers or the securities mature. Equity securities: Other investment securities: (non-marketable) (non-marketable), Securities Purchased Under Resale Agreements and Securities Sold Under Agreements to Repurchase: Loans: A loan is categorized as a troubled debt restructuring (“TDR”) if a concession is granted and there is deterioration in the financial condition of the borrower. A loan classified as a TDR will generally retain such classification until the loan is paid in full. However, a one-to-four-family TDRs can take the form of a reduction of the stated interest rate, splitting a loan into separate loans and leases with market terms on one loan and concessionary terms on the other loan, receipts of assets from a debtor in partial or full satisfaction of a loan, the extension of the maturity date or dates at a stated interest rate lower than the current market rate for new debt with similar risk, the reduction of the face amount or maturity amount of the debt as stated in the instrument or other agreement, or the reduction of accrued interest or any other concessionary type of renegotiated debt. Under United’s current loan policy, a loan is not recognized as a TDR until it becomes probable that the loan will be a TDR. In response to the coronavirus (“COVID-19”) COVID-19 Loans Acquired Through Transfer: Loans acquired in a business combination that have experienced more-than-insignificant deterioration in credit quality since origination are considered purchased credit deteriorated (“PCD”) loans. At the acquisition date, an estimate of expected credit losses is made for groups of PCD loans with similar risk characteristics and individual PCD loans without similar risk characteristics. This initial allowance for credit losses is allocated to individual PCD loans and added to the purchase price or acquisition date fair values to establish the initial amortized cost basis of the PCD loans. As the initial allowance for credit losses is added to the purchase price, there is no credit loss expense recognized upon acquisition of a PCD loan. Any difference between the unpaid principal balance of PCD loans and the amortized cost basis is considered to relate to noncredit factors and results in a discount or premium. Discounts and premiums are recognized through interest income on a level-yield method over the life of the loans. For loans and leases acquired after the adoption of ASC Topic 326, United will likely take several factors into consideration when determining if loans and leases meet the definition of PCD. ASC Topic 326 lists some, but not all, factors for consideration in the bifurcation of PCD versus non-PCD · Financial assets that are delinquent as of the acquisition date · Financial assets that have been downgraded since origination · Financial assets that have been placed on nonaccrual status For acquired loans not deemed purchased credit deteriorated at acquisition, the differences between the initial fair value and the unpaid principal balance are recognized as interest income on a level-yield basis over the lives of the related loans. Loans Held for Sale: one-to-four Loans held for sale are recorded under the fair value option at a fair value measured using valuations from investors for loans with similar characteristics adjusted for the Company’s actual sales experience versus the investor’s indicated pricing. Gains and losses on sale of loans are recorded within income from mortgage banking activities. Allowance for Loan and Lease Losses: charged-off, charged-off, United made a policy election to present the accrued interest receivable balance separately in its consolidated balance sheets from the amortized cost of a loan. United estimates the allowance balance using relevant available information, from internal and external sources, relating to past events, current conditions and reasonable and supportable forecasts. Historical credit loss experience provides the basis for the estimation of expected credit losses. Adjustments to historical loss information are made for differences in current loan-specific risk characteristics such as differences in underwriting standards, portfolio mix, delinquency level or term as well as reasonable and supportable forecast adjustments for changes in environmental conditions, such as changes in unemployment rates, property values or other relevant factors. A reversion to historical loss data occurs via a straight-line method during the year following the one-year United pools its loans and leases based on similar risk characteristics in estimating expected credit losses. United has identified the following portfolio segments and measures the allowance for credit losses using the following methods: · Method: Probability of Default/Loss Given Default (PD/LGD) Ø Commercial Real Estate Owner-Occupied Ø Commercial Real Estate Nonowner-Occupied Ø Commercial Other · Method: Cohort Ø Residential Real Estate Ø Construction & Land Development Ø Consumer Ø Bankcard Risk characteristics of commercial real estate owner-occupied loans and commercial other loans and leases are similar in that they are normally dependent upon the borrower’s internal cash flow from operations to service debt. Commercial real estate nonowner-occupied loans differ in that cash flow to service debt is normally dependent on external income from third parties for use of the real estate such as rents, leases and room rates. Residential real estate loans are dependent upon individual borrowers who are affected by changes in general economic conditions, demand for housing and resulting residential real estate valuation. Construction and land development loans are impacted mainly by demand whether for new residential housing or for retail, industrial, office and other types of commercial construction within a given area. Consumer loan pool risk characteristics are influenced by general, regional and local economic conditions. Loans that do not share risk characteristics are evaluated on an individual basis. Loans evaluated individually are not also included in the collective evaluation. When management determines that foreclosure is probable or when the borrower is experiencing financial difficulty at the reporting date and repayment is expected to be provided substantially through the operation or sale of the collateral but may also include other non-performing Expected credit losses are estimated over the contractual term of the loans and leases, 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 troubled debt restructuring will be executed with an individual borrower, or the extension or renewal options are included in the original or modified contract at the reporting date and are not unconditionally cancelable by United. At the acquisition date, an initial allowance for expected credit losses for non-PCD Bank Premises and Equipment: three five Other Real Estate Owned , allowance for loan losses. Any subsequent valuation adjustments as well as any costs relating to operating, holding or disposing of the property are recorded in other expense in the period incurred. At December 31, 2022 and 2021, the recorded investment of consumer mortgage loans secured by residential real estate properties for which formal foreclosure proceedings are in process was $ and $ , respectively. Intangible Assets: one ten-year , , Goodwill is tested for impairment at least annually or sooner if indicators of impairment exist. United may elect to perform a qualitative analysis to determine whether or not it is more-likely-than not that the fair value of a reporting unit is less than its carrying amount. If United elects to bypass this qualitative analysis, or concludes via qualitative analysis that it is more-likely-than-not , 000 ,000 Mortgage Servicing Rights, Fees and Costs: MSRs are amortized in proportion to, and over the period of, estimated net servicing income. The amortization of the MSRs is analyzed periodically and is adjusted to reflect changes in prepayment rates and other estimates. The Company evaluates potential impairment of MSRs based on the difference between the carrying amount and current estimated fair value of the servicing rights. In determining impairment, the Company aggregates all servicing rights and stratifies them into tranches based on predominant risk characteristics. If impairment exists, a valuation allowance is established for any excess of amortized cost over the current estimated fair value by a charge to income. If the Company later determines that all or a portion of the impairment no longer exists for a particular tranche, a reduction of the allowance may be recorded as an increase to income. Service fee income is recorded for fees earned for servicing mortgage loans under servicing agreements with the Federal National Mortgage Association (“FNMA”), the Federal Home Loan Mortgage Corporation (“FHLMC”), Government National Mortgage Association (“GNMA”) and certain private investors. The fees are based on a contractual percentage of the outstanding principal balance of the loans serviced and are recorded in noninterest income. Amortization of MSRs and mortgage servicing costs are charged to expense when incurred. Accrued Interest Receivable • Presenting accrued interest receivable balances separately from their underlying instruments within the consolidated statements of financial condition. • Excluding accrued interest receivable that is included in the amortized cost of financing receivables from related disclosure requirements. • Continuing our policy to write off accrued interest receivable by reversing interest income in cases where the Company does not reasonably expect to receive payment. • Generally, not measuring an allowance for credit losses for accrued interest receivable due to the Company’s policy of writing off uncollectible accrued interest receivable balances in a timely manner. However, due to loan interest payment deferrals on certain loans and leases granted by United under the CARES Act, United assessed the collectability of the accrued interest receivables on these deferring loans and leases. As a result of this assessment, United did not record an allowance for credit losses for accrued interest receivables not expected to be collected as of December 31, 2022 as compared to an allowance for credit losses of $8,000 as of December 31, 2021 Revenue Recognition Descriptions of our revenue-generating activities that are within the scope of ASC Topic 606, which are presented in our Consolidated Statements of Income as components of Other Income are discussed below. There are no significant judgements relating to the amount and timing of revenue recognition for those revenue streams under the scope of ASC Topic 606. Fees from Trust Services Revenue from trust services primarily is comprised of fees earned from the management and administration of trusts and other customer assets. Trust services include custody of assets, investment management, escrow services, and similar fiduciary activities. The Company’s performance obligation is generally satisfied over time and the resulting fees are recognized monthly, based upon the month-end Fees from Brokerage Services Revenue from brokerage services are recorded as the income is earned at the time the related service is performed. In return for such services, the Company charges a commission for the sales of various securities products primarily consisting of investment company shares, annuity products, and corporate debt and equity securities, for its selling and administrative efforts. For account supervision, advisory and administrative services, revenue is recognized over a period of time as earned based on customer account balances and activity. Fees from Deposit Services Service charges on deposit accounts consist of account analysis fees (i.e., net fees earned on analyzed business and public checking accounts), monthly service fees, check orders, ATM activity fees, debit card fees, and other deposit account related fees. Revenue is recognized when our performance obligation is completed which is generally monthly for account maintenance services or when a transaction has been completed (ATM or debit card activity). Bankcard Fees and Merchant Discounts Bankcard fees and merchant discounts are primarily comprised of credit card income and merchant services income. Credit card income is primarily comprised of interchange fees earned whenever the Company’s credit cards are processed through card payment networks such as Visa. Merchant services income mainly represents fees charged to merchants to process their credit card transactions. The Company’s performance obligation for bankcard fees and interchange are largely satisfied, and related revenue recognized at the time services are rendered. Payment is typically received immediately or in the following month. Advertising Costs: Income Taxes: more-likely-than-not For uncertain income tax positions, United records a liability based on a recognition threshold of more-likely-than-not, United files a consolidated income tax return with its subsidiaries. Federal income tax expense or benefit has been allocated to subsidiaries on a separate return basis. Derivative Financial Instruments: Derivative instruments designated in a hedge relationship to mitigate exposure to changes in the fair value of an asset, liability, or firm commitment attributable to a particular risk, such as interest rate risk, are considered fair value hedges. Derivative instruments designated in a hedge relationship to mitigate exposure to variability in expected future cash flows, or other types of forecasted transactions, are considered cash flow hedges. For a fair value hedge, the fair value of the interest rate swap is recognized on the balance sheet as either a freestanding asset or liability with a corresponding adjustment to the hedged financial instrument. Subsequent adjustments due to changes in the fair value of a derivative that qualifies as a fair value hedge are offset in current period earnings either in interest income or interest expense depending on the nature of the hedged financial instrument. For a cash flow hedge, the fair value of the interest rate swap is recognized on the balance sheet as either a freestanding asset or liability with a corresponding adjustment to accumulated other comprehensive income within shareholders’ equity, net of tax. Subsequent adjustments due to changes in the fair value of a derivative that qualifies as a cash flow hedge are offset to accumulated other comprehensive income, net of tax and reclassified into earnings in the same line associated with the forecasted transaction when the forecasted transaction affects earnings. Fair value hedges may be eligible for offset on the consolidated balance sheets because they are subject to master netting arrangements or similar agreements. United has elected not to offset the assets and liabilities subject to such arrangements on the consolidated financial statements. At inception of a hedge relationship, United formally documents the hedged item, the particular risk management objective, the nature of the risk being hedged, the derivative being used, how effectiveness of the hedge will be assessed and how the ineffectiveness of the hedge will be measured. United also assesses hedge effectiveness at inception and on an ongoing basis using regression analysis. Hedge ineffectiveness is measured by using the change in fair value method. The change in fair value method compares the change in the fair value of the hedging derivative to the change in the fair value of the hedged exposure, attributable to changes in the benchmark rate. United through its mortgage banking subsidiaries enters into interest rate lock commitments to finance residential mortgage loans with its customers. These commitments, which contain fixed expiration dates, offer the borrower an interest rate guarantee provided the loan meets underwriting guidelines and closes within the timeframe established by United. Interest rate risk arises on these commitments and subsequently closed loans if interest rates change between the time of the interest rate lock and the delivery of the loan to the investor. Market risk on interest rate lock commitments and mortgage loans held for sale is managed using corresponding forward mortgage loan sales contracts. United is a party to these forward mortgage loan sales contracts to sell loans with servicing either released or retained and short sales of mortgage-backed securities. When the interest rate is locked with the borrower, the rate lock commitment, forward sale agreement, and mortgage-backed security position are undesignated derivatives and marked to fair value through earnings. The fair value of the rate lock derivative is measured using valuations from investors for loans with similar characteristics as well as considering the probability of the loan closing (i.e. the “pull-through” rate) with some adjusted for the Company’s actual sales experience versus the investor’s indicated pricing. Fair values of TBA mortgage-backed securities are measured using valuations from investors for mortgage-backed securities with similar characteristics. Income from mortgage banking activities includes the gain recognized for the period presented and associated elements of fair value. United is subject to the Dodd-Frank Act clearing requirement for eligible derivatives. United has executed and cleared eligible derivatives through the London Clearing House (“LCH”). Variation margin at the LCH is distinguished as settled-to-market collateralized-to-market. For derivatives that are not designated in a hedge relationship, changes in the fair value of the derivatives are recognized in earnings in the same period as the change in the fair value. Off-balance-sheet : off-balance Stock-Based Compensation Stock-based compensation expense was $9,881,000 in 2022, $8,018,000 in 2021, and $5,980,000 in 2020. Treasury Stock Trust Assets and Income: Earnings Per Common Share: two-class non-vested Under the two-class The reconciliation of the numerator and denominator of basic earnings per share with that of diluted earnings per share is presented as follows: Year Ended December 31 (Dollars in thousands, except per share) 2022 2021 2020 Distributed earnings allocated to common stock $ 194,052 $ 181,614 $ 171,403 Undistributed earnings allocated to common stock 184,572 185,082 116,879 Net earnings allocated to common shareholders $ 378,624 $ 366,696 $ 288,282 Average common shares outstanding 134,776,241 129,276,452 120,017,247 Dilutive effect of stock compensation 341,271 236,401 72,985 Average diluted shares outstanding 135,117,512 129,512,853 120,090,232 Earnings per basic common share $ 2.81 $ 2.84 $ 2.40 Earnings per diluted common share $ 2.80 $ 2.83 $ 2.40 Fair Value Measurements ASC Topic 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 United’s market assumptions. The three levels of the fair value hierarchy 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 market. Level 3 - Valuation is based on model-based techniques that use one or more significant inputs or assumptions that are unobservable in the market. When determining the fair value measurements for assets and liabilities, United looks to active and observable markets to price identical assets or liabilities whenever possible and classifies such items in Level 1. When identical assets and liabilities are not traded in active markets, United looks to market observable data for similar assets and liabilities and classifies such items as Level 2. Nevertheless, certain assets and liabilities are not actively traded in observable markets and United must use alternative valuation techniques using unobservable inputs to determine a fair value and classifies such items as Level 3. For assets and liabilities that are not actively traded, the fair value measurement is based primarily upon estimates that require significant judgment. Therefore, the results may not be realized in an actual sale or immediate settlement of the asset or liability. Additionally, there are inherent weaknesses in any calculation technique, and changes in the underlying assumptions used, including discount rates and estimates of future cash flows, could significantly affect the results of current or future values. The level within the fair value hierarchy is based on the lowest level of input that is significant in the fair value measurement.

Business Combinations [Abstract]
Mergers and Acquisitions	NOTE B—MERGERS AND ACQUISITIONS On December 3, 2021 (the “Acquisition Date”), United completed its acquisition of Community Bankers Trust Corporation (“Community Bankers Trust”). Community Bankers Trust was merged with and into United (the “Merger”), pursuant to the terms of the Agreement and Plan of Reorganization, dated June 2, 2021, by and between United and Community Bankers Trust (the “Agreement”). Under the terms of the Agreement, each outstanding share of common stock of Community Bankers Trust was converted into the right to receive 0.3173 shares of United common stock, par value $2.50 per share. Also, pursuant to the Agreement, at the effective time of the Merger, each outstanding Community Bankers Trust stock option granted under a Community Bankers Trust stock plan, whether vested or unvested as of the date of the Merger, vested as provided pursuant to the terms of such Community Bankers Trust stock plan and converted into an option to acquire United common stock adjusted based on the 0.3173 exchange ratio. Also, at the effective time of the Merger, each restricted stock unit granted under a Community Bankers Trust stock plan that was outstanding immediately prior to the effective time of the Merger vested in accordance with the formula and other terms of the Community Bankers Trust stock plan and converted into the right to receive shares of United common stock based on the 0.3173 exchange ratio. Immediately following the Merger, Essex Bank, a wholly-owned subsidiary of Community Bankers Trust, merged with and into United Bank, a wholly-owned subsidiary of United (the “Bank Merger”) pursuant to an Agreement and Plan of Merger, dated June 2, 2021. United Bank survived the Bank Merger and continues to exist as a Virginia banking corporation. The Merger was accounted for under the acquisition method of accounting. The results of operations of Community Bankers Trust are included in the consolidated results of operations from the Acquisition Date. The acquisition of Community Bankers Trust enhanced United’s existing presence in the DC Metro MSA and took United into new markets including Baltimore, Annapolis, Lynchburg, Richmond, and the Northern Neck of Virginia. It also strategically connected our Mid-Atlantic non-PCD The aggregate purchase price was approximately $260,304,000, including common stock valued at $252,321,000, stock options assumed valued at $7,958,000, and cash paid for fractional shares of $25,000. The number of shares issued in the transaction was 7,135,771, which were valued based on the closing market price of $35.36 for United’s common shares on December 3, 2021. The purchase price was allocated to the identifiable tangible and intangible assets resulting in additions to goodwill, and core deposit intangibles of $78,849,000 and $3,398,000, respectively. The goodwill recognized results from the expected synergies and potential earnings from the combination of United and Community Bankers Trust. The core deposit intangible is expected to be amortized on an accelerated basis over ten years. Because the consideration paid was greater than the net fair value of the acquired assets and liabilities, the Company recorded goodwill as part of the acquisition. None of the goodwill from the Community Bankers Trust acquisition is expected to be deductible for tax purposes. United used an independent third party to help determine the fair values of the assets and liabilities acquired from Community Bankers Trust. As a result of the merger, United recorded fair value discounts of $7,744,000 on the loans and leases acquired, $230,000 on land acquired, $50,000 on OREO properties acquired and $415,000 on a trust preferred issuance, and premiums of $6,766,000 on investment securities acquired, $492,000 on buildings acquired, $2,741,000 on interest-bearing deposits, and $457,000 on long-term FHLB advances, respectively. United also recorded an allowance for credit losses, including a reserve for unfunded commitments, of $25,920,000 on the loans and commitments acquired split between $12,788,000 for purchased credit deteriorated (“PCD”) loans which is part of the acquisition date fair value, $12,288,000 for non-PCD non-PCD Portfolio loans and leases acquired from Community Bankers Trust were recorded at their fair value at the Acquisition Date based on a discounted cash flow methodology. The estimated fair value incorporates adjustments related to market loss assumptions and prevailing market interest rates for comparable assets and other market factors such as liquidity from the perspective of a market participant. Also, acquired portfolio loans and leases were evaluated upon acquisition and classified as either PCD, which indicates that the loan has experienced a more-than-insignificant deterioration in credit quality since origination, or non-PCD. non-PCD non-PCD non-PCD The following table provides a reconciliation of the difference between the purchase price and the par value of portfolio PCD loans and leases acquired from Community Bankers Trust as of the Acquisition Date: (Dollars in thousands) Purchase price of PCD loans and leases at acquisition $ 360,638 Allowance for credit losses at acquisition 12,629 Non-credit 3,559 Par value (UPB) of acquired PCD loans and leases at acquisition $ 376,826 The consideration paid for Community Bankers Trust’s common equity and the amounts of acquired identifiable assets and liabilities assumed as of the Community Bankers Trust Acquisition Date were as follows: (Dollars in thousands) Purchase price: Value of common shares issued (7,135,771 shares) $ 252,321 Fair value of stock options assumed 7,958 Cash for fractional shares 25 Total purchase price 260,304 Identifiable assets: Cash and cash equivalents 39,445 Investment securities 395,249 Net loans and leases 1,280,016 Premises and equipment 25,857 Operating lease right-of-use 8,127 Core deposit intangible 3,398 Other assets 50,851 Total identifiable assets $ 1,802,943 Identifiable liabilities: Deposits $ 1,520,243 Short-term borrowings 26,755 Long-term borrowings 51,500 Operating lease liability 8,127 Other liabilities 14,863 Total identifiable liabilities 1,621,488 Fair value of net assets acquired including identifiable intangible assets 181,455 Resulting goodwill $ 78,849

Securities with the most significant gross unrealized losses at December 31, 2022 consisted primarily of agency residential mortgage-backed securities, state and political subdivision securities, agency commercial mortgage-backed securities, asset-backed securities and other corporate securities. In determining whether or not a security is impaired, management considered the severity of the loss in conjunction with United’s positive intent and the more likely than not ability to hold these securities to recovery of their cost basis or maturity. State and political subdivisions United’s state and political subdivisions portfolio relates to securities issued by various municipalities located throughout the United States. The total amortized cost of available for sale state and political subdivision securities was $820,167,000 at December 31, 2022. As of December 31, 2022, approximately 53% of the portfolio was supported by the general obligation of the issuing municipality, which allows for the securities to be repaid by any means available to the municipality. The majority of the portfolio was rated AA or higher, and no securities within the portfolio were rated below investment grade as of December 31, 2022. In addition to monitoring the credit ratings of these securities, management also evaluates the financial performance of the underlying issuers on an ongoing basis. Based upon management’s analysis and judgment, it was determined that none of the state and political subdivision securities had credit losses at December 31, 2022. Mortgage-backed securities The fair value of mortgage-backed mortgage-backed United’s agency mortgage-backed securities portfolio relates to securities issued by Fannie Mae, Freddie Mac, and Ginnie Mae. The total amortized cost of available for sale agency mortgage-backed securities was $1,997,239,000 at December 31, 2022. Of the $1,997,239,000 amount, $627,768,000 was related to agency commercial mortgage-backed securities and $1,369,471,000 was related to agency residential mortgage-backed securities. Each of the agency mortgage-backed securities provides a guarantee of full and timely payments of principal and interest by the issuing agency. Based upon management’s analysis and judgment, it was determined that none of the agency mortgage-backed securities had credit losses at December 31, 2022. United’s non-agency non-agency non-agency Asset-backed securities As of December 31, 2022, United’s asset-backed securities portfolio had a total amortized cost balance of $943,813,000. 100% of the portfolio was investment grade rated as of December 31, 2022. Approximately 27% of the portfolio relates to securities that are backed by Federal Family Education Loan Program (“FFELP”) student loan collateral which includes a minimum of a 97% government repayment guaranty, as well as additional credit support and subordination in excess of the government guaranteed portion. Approximately 73% of the portfolio relates to collateralized loan obligation securities that are all AAA rated. Upon reviewing this portfolio as of December 31, 2022, it was determined that none of the asset-backed securities had credit losses. Single issue trust preferred securities The majority of United’s single issue trust preferred portfolio consists of obligations from large cap banks (i.e. banks with market capitalization in excess of $10 billion). All single issue trust preferred securities are currently receiving interest payments. The amortized cost of available for sale single issue trust preferred securities as of December 31, 2022 consisted of $8,468,000 in investment grade bonds, $3,086,000 in split rated bonds, and $5,788,000 in unrated bonds. Management reviews each issuer’s current and projected earnings trends, asset quality, capitalization levels, and other key factors. Upon completing the review for the fourth quarter of 2022, it was determined that none of the single issue trust preferred securities had credit losses. Corporate securities As of December 31, 2022, United’s Corporate securities portfolio had a total amortized cost balance of $563,425,000. The majority of the portfolio consisted of debt issuances of corporations representing a variety of industries, including financial institutions. Of the $563,425,000, 98% had at least one rating above investment grade, none were below investment grade rated, and 2% was unrated. For corporate securities, management has evaluated the near-term prospects of the investment in relation to the severity of any unrealized loss. Based upon management’s analysis and judgment, it was determined that none of the corporate securities had credit losses at December 31, 2022. The amortized cost and estimated fair value of securities available for sale at December 31, 2022 by contractual maturity are shown below. Expected maturities may differ from contractual maturities because the issuers may have the right to call or prepay obligations without penalties. Maturities of mortgage-backed securities with an amortized cost of $2,118,575,000 and an estimated fair value of $1,849,470,000 at December 31, 2022 are included below based upon contractual maturity.

United determined that there was no individual security that experienced an adverse event during the fourth quarter. There were no other events or changes in circumstances during the fourth quarter which would have an adverse effect on the recorded fair value of its cost method securities. The carrying value of securities pledged to secure public deposits, securities sold under agreements to repurchase, and for other purposes as required or permitted by law, approximated $2,412,820,000 and $1,871,328,000 at December 31, 2022 and December 31, 2021, respectively.

Credit Quality	NOTE E—CREDIT QUALITY Management monitors the credit quality of its loans and leases on an ongoing basis. Measurement of delinquency and past due status are based on the contractual terms of each loan. United considers a loan to be past due when it is 30 days or more past its contractual payment due date. For all loan classes, past due loans and leases are reviewed on a monthly basis to identify loans and leases for nonaccrual status. Generally, when collection in full of the principal and interest is jeopardized, the loan is placed on nonaccrual status. The accrual of interest income on commercial and most consumer loans generally is discontinued when a loan becomes 90 to 120 days past due as to principal or interest. However, regardless of delinquency status, if a loan is fully secured and in the process of collection and resolution of collection is expected in the near term (generally less than 90 days), then the loan will not be placed on nonaccrual status. When interest accruals are discontinued, unpaid interest recognized in income in the current year is reversed, and unpaid interest accrued in prior years is charged to the allowance for credit losses. United’s method of income recognition for loans and leases that are classified as nonaccrual is to recognize interest income on a cash basis or apply the cash receipt to principal when the ultimate collectibility of principal is in doubt. Nonaccrual loans and leases will not normally be returned to accrual status unless all past due principal and interest has been paid and the borrower has evidenced their ability to meet the contractual provisions of the note. Generally, a loan is categorized as a TDR if a concession is granted and there is deterioration in the financial condition of the borrower. The portfolio of TDR loans is monitored monthly. In response to the coronavirus (“COVID-19”) COVID-19 under the CARES Act, these loan modifications were exempt by law from classification as a TDR as defined by GAAP. As of December 31, 2022, United no longer has any eligible loan modifications in deferral under section 4013, “Temporary Relief from Troubled Debt Restructurings,” of the CARES Act as compared to 188 eligible loan modifications in deferral on $18,039 ,000 As of December 31, 2022, United had TDRs of $19,388 ,000 ,000 ,000 ,000 30-89 ,000 ,000 ,000 The following tables sets forth the balances of TDRs at December 31, 2022 and December 31, 2021 and the reasons for modification: (In thousands) Reason for modification December 31, 2022 December 31, 2021 Interest rate reduction $ 736 $ 3,163 Interest rate reduction and change in terms 792 1,412 Forgiveness of principal 0 0 Concession of principal and term 15 19 Extended maturity 4,616 4,831 Transfer of asset 0 5,407 Change in terms 13,229 21,024 Total $ 19,388 $ 35,856 The following table sets forth United’s troubled debt restructurings that have been restructured during the year ended December 31, 2022 and 2021, segregated by class of loans: Troubled Debt Restructurings For the Year Ended December 31, 2022 December 31, 2021 (Dollars in thousands) Number of Pre- Modification Post- Number of Pre- Modification Post- Commercial real estate: Owner-occupied 2 $ 2,945 $ 2,817 5 $ 2,155 $ 2,293 Nonowner-occupied 0 0 0 3 6,362 6,130 Other commercial 1 132 0 2 328 328 Residential real estate 0 0 0 9 1,660 1,651 Construction & land development 0 0 0 0 0 0 Consumer: Bankcard 0 0 0 0 0 0 Other consumer 0 0 0 0 0 0 Total 3 $ 3,077 $ 2,817 19 $ 10,505 $ 10,402 The following table sets forth United’s troubled debt restructurings, based on their post-modification outstanding recorded balance, that have been restructured during the year ended December 31, 2022 and 2021, segregated by the reason for modification: Year Ended (In thousands) Reason for modification December 31, December 31, Interest rate reduction $ 143 $ 155 Interest rate reduction and change in terms 0 1,412 Forgiveness of principal 0 0 Year Ended (In thousands) Reason for modification December 31, December 31, Concession of principal and term 0 0 Transfer of asset 0 5,407 Extended maturity 0 2,754 Change in terms 2,674 674 Total $ 2,817 $ 10,402 The loans and leases were evaluated individually for allocation within United’s allowance for loan losses.

United uses the following definitions for risk ratings: · Pass · Special Mention · Substandard · Doubtful For United’s loans with a corporate credit exposure, United analyzes loans individually to classify the loans as to credit risk. Review and analysis of criticized (special mention-rated loans in the amount of $1,000,000 or greater) and classified (substandard-rated and worse in the amount of $500,000 and greater) loans is completed once per quarter. Review of notes with committed exposure of $2,000,000 or greater is completed at least annually. For loans with a consumer credit exposure, United internally assigns a grade based upon an individual loan’s delinquency status. United reviews and updates, as necessary, these grades on a quarterly basis. Special mention loans, with a corporate credit exposure, have potential weaknesses that deserve management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loans or in the Company’s credit position at some future date. Borrowers may be experiencing adverse operating trends (declining revenues or margins) or an ill proportioned balance sheet (e.g., increasing inventory without an increase in sales, high leverage, tight liquidity). Adverse economic or market conditions, such as interest rate increases or the entry of a new competitor, may also support a special mention rating. Nonfinancial reasons for rating a credit exposure special mention include management problems, pending litigation, an ineffective loan agreement or other material structural weakness, and any other significant deviation from prudent lending practices. For loans with a consumer credit exposure, loans that are past due 30-89 A substandard loan with a corporate credit exposure is inadequately protected by the current sound worth and paying capacity of the obligor or of the collateral pledged, if any. Loans so classified have a well-defined weakness, or weaknesses, that jeopardize the liquidation of the debt by the borrower. They are characterized by the distinct possibility that the Company will sustain some loss if the deficiencies are not corrected. They require more intensive supervision by management. Substandard loans are generally characterized by current or expected unprofitable operations, inadequate debt service coverage, inadequate liquidity, or marginal capitalization. Repayment may depend on collateral or other credit risk mitigants. For some substandard loans, the likelihood of full collection of interest and principal may be in doubt and thus, placed on nonaccrual. For loans with a consumer credit exposure, loans that are 90 days or more past due or that have been placed on nonaccrual are considered substandard. A loan with corporate credit exposure is classified as doubtful if it has all the weaknesses inherent in one classified as substandard with the added characteristic that the weaknesses make collection in full, on the basis of currently existing facts, conditions, and values, highly questionable. A doubtful loan has a high probability of total or substantial loss, but because of specific pending events that may strengthen the loan, its classification as loss is deferred. Doubtful borrowers are usually in default, lack adequate liquidity or capital, and lack the resources necessary to remain an operating entity. Pending events can include mergers, acquisitions, liquidations, capital injections, the perfection of liens on additional collateral, the valuation of collateral, and refinancing. Generally, there are not any loans with a consumer credit exposure that are classified as doubtful. Usually, they are charged-off Based on the most recent analysis performed, the risk category of loans and leases by class of loans is as follows: Commercial Real Estate – Owner-occupied Revolving (In

Allowance for Credit Losses

Allowance for Credit Losses	12 Months Ended

Receivables [Abstract]
Allowance for Credit Losses	N OTE F—ALLOWANCE FOR CREDIT LOSSES The allowance for loan losses is an estimate of the expected credit losses on financial assets measured at amortized cost to present the net amount expected to be collected as of the balance sheet date. Such allowance is based on the credit losses expected to arise over the life of the asset (contractual term). Assets are charged off when United determines that such financial assets are deemed uncollectible or based on regulatory requirements, whichever is earlier. Charge-offs are recognized as a deduction from the allowance for credit losses. Expected recoveries of amounts previously charged-off, charged-off, United made a policy election to present the accrued interest receivable balance separately in its consolidated balance sheets from the amortized cost of a loan. Accrued interest receivable was $70,332,000 (no allowance for credit losses) and $49,029,000 (net of an allowance for credit losses of $8,000) at December 31, 2022 and December 31, 2021, respectively, related to loans and leases are included separately in “Accrued interest receivable” in the consolidated balance sheets. Due to loan interest payment deferrals granted by United under the CARES Act, United assessed the collectability of the accrued interest receivables on these deferring loans and leases. As a result of this assessment, United did not record an allowance for credit losses for accrued interest receivables not expected to be collected as of December 31, 2022 as compared to an allowance for credit losses of $8,000 as of December 31, 2021. For all classes of loans and leases receivable, the accrual of interest is discontinued when the contractual payment of principal or interest has become 90 days past due, unless the loan is well secured and in the process of collection. Interest received on nonaccrual loans and leases, generally is either applied against principal or reported as interest income, according to management’s judgment as to the collectability of principal. The following table represents the accrued interest receivable as of December 31, 2022 and December 31, 2021: Accrued Interest Receivable (In thousands) At December 31, 2022 At December 31, 2021 Commercial Real Estate: Owner-occupied $ 4,855 $ 4,172 Nonowner-occupied 19,801 14,901 Other Commercial 10,904 9,335 Accrued Interest Receivable (In thousands) At December 31, 2022 At December 31, 2021 Residential Real Estate 16,117 10,347 Construction 15,195 7,411 Consumer: Bankcard 0 0 Other consumer 3,460 2,871 $ 70,332 $ 49,037 Less: Allowance for credit losses 0 (8 ) Total $ 70,332 $ 49,029 The following table represents the accrued interest receivables written off by reversing interest income for the year ended December 31, 2022 and December 31, 2021: Accrued Interest Receivables Written Off (In thousands) Year Ended 2022 2021 Commercial Real Estate: Owner-occupied $ 20 $ 33 Nonowner-occupied 4 114 Other Commercial 77 40 Residential Real Estate 105 419 Construction 0 8 Consumer: Bankcard 0 0 Other consumer 304 176 Total $ 510 $ 790 United maintains an allowance for loan losses and a reserve for lending-related commitments such as unfunded loan commitments and letters of credit. For a detailed discussion of the methodology used to estimate the reserve for lending-related commitments, see Note A, “Summary of Significant Accounting Policies.” The reserve for lending-related commitments of $46,189,000 and $31,442,000 at December 31, 2022 and December 31, 2021, respectively, is separately classified on the balance sheet and is included in other liabilities. The combined allowance for loan losses and reserve for lending-related commitments is considered the allowance for credit losses. United continuously evaluates any risks which may impact its loan and lease portfolios. Reserves are initially determined based on losses identified from the PD/LGD and Cohort models which utilize the Company’s historical information.

Leases [Abstract]
Leases	NOTE H—LEASES United determines if an arrangement is a lease at inception. United and certain subsidiaries have entered into various noncancelable-operating leases for branch and loan production offices as well as operating facilities. Operating leases are included in operating lease right-of-use United’s operating leases are subject to renewal options under various terms. United’s operating leases have remaining terms of 1 to 15 years, some of which include options to extend leases generally for periods of 5 years. United rents or subleases certain real estate to third parties. Our sublease portfolio generally consists of operating leases to other organizations for former branch offices. ROU assets represent United’s right to use an underlying asset for the lease term and lease liabilities represent United’s obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As most of United’s leases do not provide an implicit rate, the Company uses its incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. The operating lease ROU asset also includes any lease payments made and excludes lease incentives. Lease terms may include options to extend the lease when it is reasonably certain that United will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term. The components of lease expense were as follows: Year Ended Year Ended (In thousands) Classification December 31, December 31, Operating lease cost Net occupancy expense $ 20,987 $ 21,466 Sublease income Net occupancy expense (328 ) (1,256 ) Net lease cost $ 20,659 $ 20,210 Supplemental balance sheet information related to leases was as follows: (In thousands) Classification December 31, December 31, Operating lease right-of-use Operating lease right-of-use $ 71,144 $ 81,942 Operating lease liabilities Operating lease liabilities $ 75,749 $ 86,703 Other information related to leases was as follows: December 31, 2022 Weighted-average remaining lease term: Operating leases 6.70 years Weighted-average discount rate: Operating leases 2.25 % Supplemental cash flow information related to leases was as follows: Year Ended (In thousands) December 31, 2022 December 31, 2021 Cash paid for amounts in the measurement of lease liabilities: Operating cash flows from operating leases $ 21,240 $ 22,153 ROU assets obtained in the exchange for lease liabilities 9,184 22,719 Maturities of lease liabilities by year and in the aggregate, under operating leases with initial or remaining terms of one year or more, for years subsequent to December 31, 2022, consists of the following: Year Amount (Dollars in thousands) 2023 $ 19,157 2024 13,795 2025 10,167 2026 8,872 2027 7,036 Thereafter 22,447 Total lease payments 81,474 Less: imputed interest (5,725 ) Total $ 75,749

Income taxes paid approximated $93,680,000, $101,227,000, and $65,378,000 in 2022, 2021 and 2020, respectively. Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. At December 31, 2022, United had no federal or state net operating loss carryforwards. Taxes not on income, which consists mainly of business franchise taxes, were $13,537,000, $12,412,000, and $12,122,000, for the years ended December 31, 2022, 2021 and 2020, respectively. These amounts are recorded in other expense in the Consolidated Statements of Income. Significant components of United’s deferred tax assets and liabilities (included in other assets in the Consolidated Balance Sheets) at December 31, 2022 and 2021 are as follows: (In thousands) 2022 2021 Deferred tax assets: Allowance for credit losses $ 65,453 $ 57,659 Accrued benefits payable 17,333 17,204 Other accrued liabilities 655 655 Unrealized loss on securities available for sale 109,185 0 Other real estate owned 531 1,706 Lease liabilities under operating leases 17,650 20,202 Deferred mortgage points 4,094 5,413 Total deferred tax assets 214,901 102,839 Deferred tax liabilities: Premises and equipment 6,707 6,750 Unrealized gain on securities available for sale 0 2,890 Right-of-use 16,576 19,092 Pension plan accruals 5,858 4,497 Derivatives 16,104 4,970 Purchase accounting intangibles 5,241 6,369 Other 365 957 Total deferred tax liabilities 50,851 45,525 Net deferred tax assets $ 164,050 $ 57,314 At December 31, 2022 and 2021, United believes that all of the deferred tax amounts shown above are more likely than not to be realized based on an assessment of all available positive and negative evidence and therefore no valuation allowance has been recorded. In accordance with ASC Topic 740, “Income Taxes,” United records a liability for uncertain income tax positions based on a recognition threshold of more-likely-than-not, Below is a reconciliation of the total amounts of unrecognized tax benefits: December 31 (In thousands) 2022 2021 Unrecognized tax benefits at beginning of year $ 1,667 $ 2,203 Increase in unrecognized tax benefits as a result of tax positions taken during the current period 1,423 199 Decreases in the unrecognized tax benefits as a result of a lapse of the applicable statute of limitations (569 ) (735 ) Unrecognized tax benefits at end of year $ 2,521 $ 1,667 The entire amount of unrecognized tax benefits, if recognized, would impact United’s effective tax rate. Over the next 12 months, the statute of limitations will close on certain income tax returns. However, at this time, United cannot reasonably estimate the amount of tax benefits, if any, it may recognize over the next 12 months. United is currently open to audit under the statute of limitations by the Internal Revenue Service for the years ended December 31, 2019, 2020 and 2021 and certain State Taxing authorities for the years ended December 31, 2019 through 2021. As of December 31, 2022, and 2021, the total amount of accrued interest related to uncertain tax positions was $525,000 and $727,000, respectively. United accounts for interest and penalties related to uncertain tax positions as part of its provision for federal and state income taxes. No interest or penalties were recognized in the results of operations for the years of 2022, 2021 and 2020.

Retirement Benefits [Abstract]
Employee Benefit Plans	NOTE P—EMPLOYEE BENEFIT PLANS United has a defined benefit retirement plan covering qualified employees. Pension benefits are based on years of service and the average of the employee’s highest five consecutive plan years of basic compensation paid during the ten plan years preceding the date of determination. Contributions by United are intended to provide not only for benefits attributed to service to date, but also for those expected to be earned in the future. In September of 2007, after a recommendation by United’s Pension Committee and approval by United’s Board of Directors, the United Bankshares, Inc. Pension Plan (the “Plan”) was amended to change the participation rules. The decision to change the participation rules for the Plan followed current industry trends, as many large and medium size companies have taken similar steps. The amendment provided that employees hired on or after October 1, 2007, will not be eligible to participate in the Plan. However, new employees will continue to be eligible to participate in United’s Savings and Stock Investment 401(k) plan. This change had no impact on current employees hired prior to October 1, 2007 as they will continue to participate in the Plan, with no change in benefit provisions, and will continue to be eligible to participate in United’s Savings and Stock Investment 401(k) Plan. Net periodic pension costs, except for service cost, are recognized in employee benefits on the consolidated statements of income. Service cost is recognized in employee compensation. Net consolidated periodic pension cost included the following components: (Dollars in thousands) Year Ended December 31, 2022 2021 2020 Service cost $ 2,669 $ 2,936 $ 2,742 Interest cost 4,988 4,241 5,222 Expected return on plan assets (12,942 ) (11,874 ) (11,010 ) Recognized net actuarial loss 3,645 6,770 6,050 Net periodic pension (income) cost $ (1,640 ) $ 2,073 $ 3,004 Weighted-Average Assumptions: Discount rate 3.08 % 2.81 % 3.42 % Expected return on assets 6.25 % 6.25 % 6.75 % Rate of compensation increase (prior to age 40) 5.00 % 5.00 % 5.00 % Rate of compensation increase (ages 40-54) 4.00 % 4.00 % 4.00 % Rate of compensation increase (otherwise) 3.50 % 3.50 % 3.50 % Amounts related to the Plan recognized as a component of other comprehensive income were as follows: (In thousands) Year Ended December 31, 2022 2021 2020 Net actuarial (gain) loss $ (2,195 ) $ (14,286 ) $ 10,583 Amortization of actuarial loss (3,645 ) (6,770 ) (6,050 ) Total recognized in other comprehensive income $ (5,840 ) $ (21,056 ) $ 4,533 Included in accumulated other comprehensive income at December 31, 2022 are unrecognized actuarial losses of $38,530,000 ($29,553,000 net of tax) that have not yet been recognized in net periodic pension cost. The reconciliation of the beginning and ending balances of the projected benefit obligation and the fair value of plan assets for the years ended December 31, 2022 and 2021 and the accumulated benefit obligation at December 31, 2022 and 2021 are as follows: (Dollars in thousands) December 31, 2022 2021 Change in Projected Benefit Obligation Projected Benefit Obligation at the Beginning of the Year $ 192,973 $ 194,775 Service Cost 2,669 2,936 Interest Cost 4,988 4,241 Actuarial Gain (46,617 ) (2,369 ) Annuity Purchase Payment (7,312 ) 0 Benefits Paid (6,092 ) (6,610 ) Projected Benefit at the End of the Year $ 140,609 $ 192,973 Accumulated Benefit Obligation at the End of the Year $ 129,927 $ 175,953 Change in Plan Assets Fair Value of Plan Assets at the Beginning of the Year $ 210,204 $ 193,022 Actual Return on Plan Assets (31,480 ) 23,792 Annuity Purchase Payment (7,312 ) 0 Benefits Paid (6,092 ) (6,610 ) Fair value of plan assets at end of year $ 165,320 $ 210,204 Net Amount Recognized Funded Status $ 24,710 $ 17,230 Unrecognized Net Loss 38,530 44,370 Net Amount Recognized $ 63,240 $ 61,600 Weighted-Average Assumptions at the End of the Year Discount Rate 5.25 % 3.08 % Rate of compensation Increase (prior to age 40) 5.00 % 5.00 % Rate of compensation Increase (ages 40-54) 4.00 % 4.00 % Rate of compensation Increase (otherwise) 3.50 % 3.50 % Asset allocation for the defined benefit pension plan as of the measurement date, by asset category, is as follows: Plan Assets Target Allocation 2023 Allowable Allocation Range Percentage of Plan Assets at December 31, December 31, Equity Securities 60 % 50-70 % 66% 65% Debt Securities 30 % 20-50 % 32% 34% Other 10 % 3-15 % 2% 1% Total 100% 100% Equity securities include United common stock in the amounts of $4,285,000 (4%) at December 31, 2022 and $3,839,000 (3%) at December 31, 2021 . The policy, as established by the Pension Committee, primarily consisting of United’s Executive Management, is to invest assets based upon the target allocations stated above. The assets are reallocated periodically to meet the above target allocations. The investment policy is reviewed at least annually, subject to the approval of the Pension Committee, to determine if the policy should be changed. Prohibited investments include, but are not limited to, futures contracts, private placements, uncovered options, real estate, the use of margin, short sales, derivatives for speculative purposes, and other investments that are speculative in nature. In order to achieve a prudent level of portfolio diversification, the securities of any one company are not to exceed 10% of the total plan assets, and no more than the 15% of total plan assets is to be invested in any one industry (other than securities of U.S. Government or Agencies). Additionally, no more than 15% of the plan assets is to be invested in foreign securities, both equity and fixed. The expected long-term rate of return for the plan’s total assets is based on the expected return of each of the above categories, weighted based on the median of the target allocation for each class. United uses the corridor approach based on 10% of the greater of the projected benefit obligation and the market-related value of plan assets to amortize actuarial gains and losses. At December 31, 2022, the benefits expected to be paid in each of the next five fiscal years, and in the aggregate for the five years thereafter are as follows: Year Amount (Dollars in thousands) 2023 $ 6,671 2024 6,727 2025 7,206 2026 7,650 2027 8,104 2028 through 2032 45,637 United made a discretionary contribution of $20,000,000 during the third quarter of 2020. United did not contribute to the plan in 2022 or in 2021 as no contributions were required by funding regulations or law. For 2023, no contributions to the plan are required by funding regulations or law. However, United may make a discretionary contribution in 2023, the amount of which cannot be reasonably estimated at this time. In accordance with ASC Topic 715 and using the guidance contained in ASC Topic 820, the following is a description of the valuation methodologies used to measure the plan assets at fair value. Cash and Cash Equivalents: Debt Securities Common and Preferred Stock: Mutual Funds: The following tables present the balances of the plan assets, by fair value hierarchy level, as of December 31, 2022 and 2021: Fair Value Measurements at December 31, 2022 Using (In thousands) Description Balance as of December 31, Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Cash and Cash equivalents $ 3,384 $ 3,384 $ 0 $ 0 Fixed Income Debt Securities: U.S. Government and agencies 3,882 3,882 Fixed Income Mutual Funds: General 49,107 49,107 0 0 Equity Securities: Common stock 28,765 28,765 0 0 Equity Mutual Funds: Global equity 1,953 1,953 0 0 Domestic equity large cap 35,738 35,738 0 0 Domestic equity small cap 15,750 15,750 0 0 Alternative equity 8,277 8,277 International emerging equity 4,925 4,925 0 0 International equity developed 13,539 13,539 0 0 Total $ 165,320 $ 165,320 $ 0 $ 0 Fair Value Measurements at December 31, 2021 Using (In thousands) Description Balance as of December 31, Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Cash and Cash equivalents $ 1,641 $ 1,641 $ 0 $ 0 Fixed Income Mutual Funds: General 72,075 72,075 0 0 Equity Securities: Common stock 34,198 34,198 0 0 Equity Mutual Funds: Global equity 5,407 5,407 0 0 Domestic equity large cap 47,387 47,387 0 0 Domestic equity small cap 30,176 30,176 0 0 International emerging equity 5,435 5,435 0 0 International equity developed 13,885 13,885 0 0 Total $ 210,204 $ 210,204 $ 0 $ 0 Common stock investments are diversified amongst various industries with no industry representing more than 5% of the total plan assets. The United Bankshares, Inc. Savings and Stock Investment Plan (the Plan) is a defined contribution plan under Section 401(k) of the Internal Revenue Code. Each employee of United, who completes ninety (90) days of qualified service, is eligible to participate in the Plan. Each participant may contribute from 1% to 100% of compensation to his/her account, subject to Internal Revenue Service maximum deferral limits. United matches 100% of the first 5% of salary deferred with United stock, subject to certain imposed limitations. Vesting is 100% for employee deferrals and the company match at the time the employee makes his/her deferral. United’s expense relating to the Plan approximated $8,242,000, $7,984,000, and $6,531,000 in 2022, 2021 and 2020, respectively. The assets of United’s defined benefit plan and 401(k) Plan each include investments in United common stock. At December 31, 2022 and 2021, the combined plan assets included 1,662,179 and 1,578,389 shares, respectively, of United common stock with an approximate fair value of $67,302,000 and $57,264,000, respectively. Dividends paid on United common stock held by the plans approximated $2,340,000, $2,060,000, and $1,776,000 for the years ended December 31, 2022, 2021, and 2020, respectively. United has certain other supplemental deferred compensation plans covering various key employees. Periodic charges are made to operations so that the liability due each employee is fully recorded as of the date of their retirement. Amounts charged to expense have not been significant in any year.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Stock Based Compensation	NOTE Q—STOCK BASED COMPENSATION On May 12, 2020, United’s shareholders approved the 2020 Long-Term Incentive Plan (“2020 LTI Plan”). The 2020 LTI Plan became effective May 13, 2020. An award granted under the 2020 LTI Plan may consist of any non-qualified non-employee non-employee S-8 During the year of 2022, a total of 156,988 shares of restricted stock and 147,511 of restricted stock units were granted under the 2020 LTI Plan. No non-qualified Stock Options United currently has options outstanding from various option plans other than the 2020 LTI Plan (the “Prior Plans”); however, no common shares of United stock are available for grants under the Prior Plans as these plans have expired. Awards outstanding under the Prior Plans will remain in effect in accordance with their respective terms. The maximum term for options granted under the plans is ten (10) years. A summary of activity under the United’s stock option plans as of December 31, 2022, and the changes during the year of 2022 are presented below: Year ended December 31, 2022 Weighted Average (Dollars in thousands, except per share amounts) Aggregate Intrinsic Remaining Contractual Exercise Shares Value Term (Yrs.) Price Outstanding at January 1, 2022 2,149,117 $ 32.01 Exercised (484,682 ) 25.16 Forfeited or expired (163,223 ) 27.88 Outstanding at December 31, 2022 1,501,212 $ 9,911 4.5 $ 34.64 Exercisable at December 31, 2022 1,330,320 $ 8,890 4.2 $ 34.66 The following table summarizes the status of United’s nonvested awards for the year ended December 31, 2022: Shares Weighted-Average Nonvested at January 1, 2022 395,034 $ 7.33 Vested (215,926 ) 8.11 Forfeited or expired (8,216 ) 11.06 Nonvested at December 31, 2022 170,892 $ 6.16 As of December 31, 2022, the total unrecognized compensation cost related to nonvested option awards was $410,000 with a weighted-average expense recognition period of 0.5 years. The total fair value of awards vested during the year ended December 31, 2022, was $1,751,000. Cash received from options exercised under the Plans for the years ended December 31, 2022, 2021 and 2020 was $10,295,000, $5,206,000, and $1,241,000, respectively. During 2022 and 2021, 484,682 and 232,777 shares, respectively, were issued in connection with stock option exercises. All shares issued in connection with stock option exercises for 2022 and 2021 were issued from authorized and unissued stock. No options were granted in 2022. The weighted-average grant-date fair value of options granted in the year of 2021 and 2020 was $5.83 and $5.65, respectively. The total intrinsic value of options exercised under the Plans during the years ended December 31, 2022, 2021, and 2020 was $6,325,000, $2,337,000, and $1,917,000, respectively. ASC Topic 230, “Statement of Cash Flows,” requires the benefits of tax deductions in excess of recognized compensation cost to be reported as an operating cash flow. This requirement reduces net operating cash flows. While the company cannot estimate what those amounts will be in the future (because they depend on, among other things, the date employees exercise stock options), United recognized cash flows used in operating activities of $1,040,000, $303,000, and $351,000 from excess tax benefits related to share-based compensation arrangements for the year of 2022, 2021 and 2020, respectively. Restricted Stock Under the 2020 LTI Plan, United may award restricted common shares to key employees and non-employee three 120 Table of Contents The following summarizes the changes to United’s restricted common shares for the year ended December 31, 2022: Number of Weighted-Average Grant Date Fair Value Per Share Outstanding at January 1, 2022 383,971 $ 35.21 Granted 156,988 36.23 Vested (158,668 ) 35.67 Forfeited (9,071 ) 35.98 Outstanding at December 31, 2022 373,220 $ 35.43 Restricted Stock Units Under the 2020 LTI Plan, United may grant restricted stock units (“RSUs”) to key employees. These awards help align the interests of these employees with the interests of the shareholders of United by providing economic value directly related to the performance of the Company. These RSU grants could be time-vested RSUs, performance-vested RSUs, or a combination of both. Currently, time-vested RSUs vest ratably over three years from the date of grant. Performance-vested RSUs cliff-vest after assessment of the Company’s performance over a period of three years. The number of performance-vested RSUs that vest is determined by two metrics measured relative to peers: Return on Average Tangible Common Equity (“ROATCE”) and Total Shareholder Return (“TSR”). Based on ASC Topic 718, the ROATCE comparison is considered a performance condition while the TSR comparison is considered a market condition. There will be no payout of the performance-vested awards if the threshold performance is not achieved. United communicates the specific threshold, target, and maximum performance-vested RSU awards and performance targets to the applicable key employees at the beginning of a performance period. Dividends are accrued but not paid in respect to the awards until the RSUs vest. The holder does not have the right to vote the shares during the time and performance periods. The value of the time-vested RSUs and the performance-vested, based on the performance condition, RSUs awarded is established as the fair market value of the stock at the time of the grant. The value of the performance-vested, based on the market condition, RSUs awarded is estimated through the use of a Monte Carlo valuation model as of the grant date. The Company recognizes expense on the RSUs in accordance with ASC Topic 718. The following table summarizes the status of United’s nonvested RSUs during the year ended December 31, 2022: Shares Weighted-Average Nonvested at January 1, 2022 136,896 $ 35.65 Granted 147,511 35.46 Vested (18,248 ) 37.05 Nonvested at December 31, 2022 266,159 $ 35.45 As of December 31, 2022, the total unrecognized compensation cost related to nonvested restricted stock units was $5,259,000 with a weighted-average expense recognition period of 0.9 years.

Commitments and Contingent Liab

Commitments and Contingent Liabilities	12 Months Ended

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingent Liabilities	NOTE R—COMMITMENTS AND CONTINGENT LIABILITIES Lending-related Commitments United is a party to financial instruments with off-balance-sheet United’s maximum exposure to credit loss in the event of nonperformance by the counterparty to the financial instrument for the loan commitments and standby letters of credit is the contractual or notional amount of those instruments. United uses the same policies in making commitments and conditional obligations as it does for on-balance 121 Table of Contents Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the commitment contract. Commitments generally have fixed expiration dates or other termination clauses and may require the payment of a fee. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily, and historically do not, represent future cash requirements. The amount of collateral obtained, if deemed necessary upon the extension of credit, is based on management’s credit evaluation of the counterparty. United had approximately $7,250,155,000 and $7,419,342,000 of loan commitments outstanding as of December 31, 2022 and December 31, 2021, respectively, approximately 34% of which contractually expire within one year. Excluded in the December 31, 2022 and December 31, 2021 amounts above are commitments to extend credit of $719,841,000 and $571,792,000, respectively, related to mortgage loan funding commitments of United’s mortgage banking segment and are of a short-term nature. Commercial and standby letters of credit are agreements used by United’s customers as a means of improving their credit standing in their dealings with others. Under these agreements, United guarantees certain financial commitments of its customers. A commercial letter of credit is issued specifically to facilitate trade or commerce. Typically, under the terms of a commercial letter of credit, a commitment is drawn upon when the underlying transaction is consummated as intended between the customer and a third party. As of December 31, 2022 and December 31, 2021, United had $16,389,000 and $14,774,000 of commercial letters of credit outstanding. A standby letter of credit is generally contingent upon the failure of a customer to perform according to the terms of an underlying contract with a third party. United has issued standby letters of credit of $147,511,000 and $164,743,000 as of December 31, 2022 and December 31, 2021, respectively. In accordance with the Contingencies Topic of the FASB Accounting Standards Codification, United has determined that substantially all of its letters of credit are renewed on an annual basis and the fees associated with these letters of credit are immaterial. Mortgage Banking United’s mortgage banking segment provides for its estimated exposure to repurchase loans previously sold to investors for which borrowers failed to provide full and accurate information on their loan application or for which appraisals have not been acceptable or where the loan was not underwritten in accordance with the loan program specified by the loan investor, and for other exposure to its investors related to loan sales activities. United evaluates the merits of each claim and estimates its reserve based on actual and expected claims received and considers the historical amounts paid to settle such claims. United’s mortgage banking segment has a reserve of $1,081,000 and $1,150,000 as of December 31, 2022 and 2021, respectively. United has derivative counter-party risk that may arise from the possible inability of United’s mortgage banking segment’s third party investors to meet the terms of their forward sales contracts. United’s mortgage banking segment works with third-party investors that are generally well-capitalized, are investment grade and exhibit strong financial performance to mitigate this risk. United does not expect any third-party investor to fail to meet its obligation. Legal Proceedings United and its subsidiaries are currently involved in various legal proceedings in the normal course of business. On at least a quarterly basis, United assesses its liabilities and contingencies in connection with all pending or threatened claims and litigation, utilizing the most recent information available. On a matter-by-matter At September 30, 2022, United accrued a $5,000,000 estimated liability related to a litigation matter with a former commercial customer. This accrual was based upon available information at that time and was subject to adjustment to reflect any subsequent developments. During the fourth quarter of 2022, the litigation was settled resulting in a reduction of $3,905,000 in the estimated liability related to this matter. Management is vigorously pursuing all its legal and factual defenses and, after consultation with legal counsel, believes that all such litigation will be resolved with no material effect on United’s financial statements. Regulatory Matters A variety of consumer products, including mortgage and deposit products, and certain fees and charges related to such products, have come under increased regulatory scrutiny. It is possible that regulatory authorities could bring enforcement actions, including civil money penalties, or take other actions against United in regard to these consumer products. United could also determine of its own accord, or be required by regulators, to refund or otherwise make remediation payments to customers in connection with these products. It is not possible at this time for management to assess the probability of a material adverse outcome or reasonably estimate the amount of any potential loss related to such matters.

Derivative Financial Instruments	NOTE S—DERIVATIVE FINANCIAL INSTRUMENTS United uses derivative instruments to help aid against adverse price changes or interest rate movements on the value of certain assets or liabilities and on future cash flows. These derivatives may consist of interest rate swaps, caps, floors, collars, futures, forward contracts, written and purchased options. United also executes derivative instruments with its commercial banking customers to facilitate its risk management strategies. During 2020, United entered into two interest rate swap derivatives designated as cash flow hedges. The notional amount of these cash flow hedge derivatives totaled $500,000,000. The derivatives are intended to hedge the changes in cash flows associated with floating rate FHLB borrowings. As of December 31, 2022, United has determined that no forecasted transactions related to its cash flow hedges resulted in gains or losses pertaining to cash flow hedge reclassification from AOCI to income because the forecasted transactions became probable of not occurring. United estimates that $22,043,000 will be reclassified from AOCI as a decrease to interest expense over the next 12-months United is subject to the Dodd-Frank Act clearing requirement for eligible derivatives. United has executed and cleared eligible derivatives through the London Clearing House (“LCH”). Variation margin at the LCH is distinguished as settled-to-market collateralized-to-market. The following tables disclose the derivative instruments’ location on the Company’s Consolidated Balance Sheets and the notional amount and fair value of those instruments at December 31, 2022 and December 31, 2021.

United’s exposure is limited to the replacement value of the contracts rather than the notional amount of the contract. The Company’s agreements generally contain provisions that limit the unsecured exposure up to an agreed upon threshold.

Regulatory Matters	NOTE V—REGULATORY MATTERS United Bank maintains average reserve balances with its Federal Reserve Bank. The average amount of those consolidated reserve balances maintained for the year ended December 31, 2022 and 2021 were approximately $1,577,485,000 and $3,119,391,000, respectively. No reserve balance for the year ended December 31, 2022 and 2021 was required. The primary source of funds for the dividends paid by United to its shareholders is dividends received from United Bank. Dividends paid by United Bank are subject to certain regulatory limitations. Generally, the most restrictive provision requires regulatory approval if dividends declared in any year exceed that year’s net income, as defined, plus the retained net profits of the two preceding years. During 2023, the retained net profits available for distribution to United by United Bank as dividends without regulatory approval, are approximately $201,101,000, plus net income for the interim period through the date of declaration. Under Federal Reserve regulation, United Bank is also limited as to the amount they may loan to affiliates, including the parent company. Loans from United Bank to the parent company are limited to 10% of the banking subsidiaries’ capital and surplus, as defined, or $395,066,000 at December 31, 2022, and must be secured by qualifying collateral. United’s subsidiary banks are subject to various regulatory capital requirements administered by federal banking agencies. Pursuant to capital adequacy guidelines, United’s subsidiary banks must meet specific capital guidelines that involve various quantitative measures of the banks’ assets, liabilities, and certain off-balance-sheet As previously mentioned, the new Basel III Capital Rules became effective for United and United Bank on January 1, 2015 (subject to a phase-in 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 United’s financial statements. As of December 31, 2022, United exceeds all capital adequacy requirements to which it is subject. At December 31, 2022, the most recent notification from its regulators, United and United Bank were categorized as well-capitalized. To be categorized as well-capitalized, United must maintain minimum total risk-based, Tier I risk-based, Common Tier I risk-based, and Tier I leverage ratios as set forth in the following table. There are no conditions or events since that notification that management believes would impact United’s well-capitalized status. United’s and United Bank’s capital amounts (in thousands of dollars) and ratios are presented in the following table.

Failure to meet minimum capital requirements of HUD can result in certain mandatory and possibly additional discretionary actions that, if undertaken, could have a direct material effect on George Mason’s and Crescent’s operations. For George Mason and Crescent, the maximum net worth requirement of HUD at December 31, 2022 was $2,500,000. George Mason’s net worth and Crescent’s net worth were $154,700,000 and $101,116,000 at December 31, 2022, which both exceeded the HUD requirements.

Fair Value Disclosures [Abstract]
Fair Values of Financial Instruments	NOTE W—FAIR VALUES OF FINANCIAL INSTRUMENTS In accordance with ASC Topic 820, the following describes the valuation techniques used by United to measure certain financial assets and liabilities recorded at fair value on a recurring basis in the financial statements. Securities available for sale and equity securities bid-ask available-for-sale Loans held for sale Derivatives For a fair value hedge, the fair value of the interest rate swap is recognized on the balance sheet as either a freestanding asset or liability with a corresponding adjustment to the hedged financial instrument. Subsequent adjustments due to changes in the fair value of a derivative that qualifies as a fair value hedge are offset in current period earnings either in interest income or interest expense depending on the nature of the hedged financial instrument. For a cash flow hedge, the fair value of the interest rate swap is recognized on the balance sheet as either a freestanding asset or liability with a corresponding adjustment to accumulated other comprehensive income within shareholders’ equity, net of tax. Subsequent adjustments due to changes in the fair value of a derivative that qualifies as a cash flow hedge are offset to accumulated other comprehensive income, net of tax and reclassified into earnings in the same line associated with the forecasted transaction when the forecasted transaction affects earnings. The Company records its interest rate lock commitments and forward loan sales commitments at fair value determined as the amount that would be required to settle each of these derivative financial instruments at the balance sheet date. In the normal course of business, United’s mortgage banking subsidiaries enter into contractual interest rate lock commitments to extend credit to borrowers with fixed expiration dates. The commitments become effective when the borrowers “lock-in” For derivatives that are not designated in a hedge relationship within the mortgage banking segment, changes in the fair value of these derivatives are recognized in income from mortgage banking activities in the same period as the change in the fair value. Unrealized gains and losses due to changes in the fair value of other derivative financial instruments not in hedge relationship, if any, are included in noninterest income and noninterest expense, respectively. The following table presents the balances of financial assets and liabilities measured at fair value on a recurring basis as of December 31, 2022 and 2021, segregated by the level of the valuation inputs within the fair value hierarchy: Fair Value at December 31, 2022 Using (In thousands) Description Balance as of December 31, 2022 Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Assets Available for sale debt securities: U.S. Treasury securities and obligations of U.S. Government corporations and agencies $ 529,492 $ 0 $ 529,492 $ 0 State and political subdivisions 709,530 0 709,530 0 Residential mortgage-backed securities Agency 1,174,944 0 1,174,944 0 Non-agency 111,973 0 111,973 0 Commercial mortgage-backed securities Agency 562,553 0 562,553 0 Asset-backed securities 911,611 0 911,611 0 Single issue trust preferred securities 16,284 0 16,284 0 Other corporate securities 525,538 5,367 520,171 0 Total available for sale securities 4,541,925 5,367 4,536,558 0 Equity securities: Financial services industry 270 270 0 0 Equity mutual funds (1) 2,221 2,221 0 0 Fixed income mutual funds 5,138 5,138 0 0 Total equity securities 7,629 7,629 0 0 Loans held for sale 56,879 0 12,008 44,871 Derivative financial assets: Fair Value at December 31, 2022 Using Description Balance as of December 31, 2022 Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Interest rate swap contracts 4,038 0 4,038 0 Forward sales commitments 220 0 214 6 TBA mortgage-backed securities 146 0 120 26 Interest rate lock commitments 1,146 0 302 844 Total derivative financial assets 5,550 0 4,674 876 Liabilities Derivative financial liabilities: TBA mortgage-backed securities 213 0 0 213 Interest rate lock commitments 348 0 0 348 Total derivative financial liabilities 561 0 0 561 Fair Value at December 31, 2021 Using (In thousands) Description Balance as of December 31, 2021 Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Assets Available for sale debt securities: U.S. Treasury securities and obligations of U.S. Government corporations and agencies $ 81,850 $ 0 $ 81,850 $ 0 State and political subdivisions 847,298 0 847,298 0 Residential mortgage-backed securities Agency 1,113,774 0 1,113,774 0 Non-agency 74,545 0 74,545 0 Commercial mortgage-backed securities Agency 639,925 0 639,925 0 Asset-backed securities 656,572 0 656,572 0 Single issue trust preferred securities 16,811 0 16,811 0 Other corporate securities 611,924 5,758 606,166 0 Total available for sale securities 4,042,699 5,758 4,036,941 0 Equity securities: Financial services industry 187 187 0 0 Equity mutual funds (1) 6,406 6,406 0 0 Fixed income mutual funds 5,811 5,811 0 0 Total equity securities 12,404 12,404 0 0 Loans held for sale 504,416 0 40,307 464,109 Derivative financial assets: Forward sales commitments 430 0 430 0 TBA mortgage-backed securities 127 0 66 61 Interest rate lock commitments 10,380 0 936 9,444 Total derivative financial assets 10,937 0 1,432 9,505 Liabilities Derivative financial liabilities: Interest rate swap contracts 3,197 0 3,197 0 Forward sales commitments 36 0 0 36 TBA mortgage-backed securities 470 0 0 470 Interest rate lock commitments 25 0 0 25 Total derivative financial liabilities 3,728 0 3,197 531 (1) The equity mutual funds are within a rabbi trust for the payment of benefits under a deferred compensation plan for certain key officers of United and its subsidiaries.

Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis Certain financial assets are measured at fair value on a nonrecurring basis in accordance with GAAP. Adjustments to the fair value of these assets usually result from the application of lower-of-cost-or-market The following describes the valuation techniques used by United to measure certain financial assets recorded at fair value on a nonrecurring basis in the financial statements. Individually assessed loans appropriate. Fair value is measured using a market approach based on the value of the collateral securing the loans. Collateral may be in the form of real estate or business assets including equipment, inventory, and accounts receivable. The vast majority of the collateral is real estate. The value of real estate collateral is determined utilizing an appraisal conducted by an independent, licensed appraiser outside of the Company using comparable property sales (“Level 2”). However, if the collateral is a house or building in the process of construction or if an appraisal of the real estate property is over two years old, then the fair value is considered Level 3. The value of business equipment is based upon an outside appraisal if deemed significant, or the net book value on the applicable business’ financial statements if not considered significant using observable market data. Likewise, values for inventory and accounts receivables collateral are based on financial statement balances or aging reports (“Level 3”). For individually assessed loans, a specific reserve is established through the allowance for loan losses, if necessary, by estimating the fair value of the underlying collateral on a nonrecurring basis. Any fair value adjustments are recorded in the period incurred as provision for credit losses expense on the Consolidated Statements of Income. OREO bi-annual Intangible Assets more-likely-than-not COVID-19 Mortgage Servicing Rights (“MSRs”): some are based on unobservable inputs and therefore are classified in Level 3 of the valuation hierarchy. The unobservable inputs for Level 3 valuations are market discount rates, anticipated prepayment speeds, projected delinquency rates, and ancillary fee income net of servicing costs. For the unobservable inputs used in the valuation of mortgage servicing rights at December 31, 2022 and 2021, refer to Note J of these Notes to Consolidated Financial Statements.

Variable Interest Entities

Variable Interest Entities	12 Months Ended
	Dec. 31, 2022
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Variable Interest Entities	NOTE X—VARIABLE INTEREST ENTITIES Variable interest entities (“VIEs”) are entities that either have a total equity investment that is insufficient to permit the entity to finance its activities without additional subordinated financial support or whose equity investors lack the characteristics of a controlling financial interest (i.e., ability to make significant decisions, through voting rights, right to receive the expected residual returns of the entity, and obligation to absorb the expected losses of the entity). VIEs can be structured as corporations, trusts, partnerships, or other legal entities. United’s business practices include relationships with certain VIEs. For United, the business purpose of these relationships primarily consists of funding activities in the form of issuing trust preferred securities. United currently sponsors twenty statutory business trusts that were created for the purpose of raising funds that originally qualified for Tier I regulatory capital. As previously discussed, these trusts now are considered Tier II regulatory capital. These trusts, of which several were acquired through bank acquisitions, issued or participated in pools of trust preferred capital securities to third-party investors with the proceeds invested in junior subordinated debt securities of United. The Company, through a small capital contribution, owns 100% of the voting equity shares of each trust. The assets, liabilities, operations, and cash flows of each trust are solely related to the issuance, administration, and repayment of the preferred equity securities held by third-party investors. United fully and unconditionally guarantees the obligations of each trust and is obligated to redeem the junior subordinated debentures upon maturity. United does not consolidate these trusts as it is not the primary beneficiary of these entities because United’s wholly owned and indirect wholly owned statutory trust subsidiaries do not have a controlling financial interest in the VIEs. A controlling financial interest is present when an enterprise has both the power to direct the activities of the VIE that most significantly impact the VIE’s economic performance and an obligation to absorb losses or the right to receive benefits that could potentially be significant to the VIE. The enterprise with a controlling financial interest, known as the primary beneficiary, consolidates the VIE. At December 31, 2022 and 2021, United’s investment (maximum exposure to loss) in these trusts were $11,277,000 and $11,032,000, respectively. United, through its banking subsidiary, also makes limited partner equity investments in various low income housing and community development partnerships sponsored by independent third-parties. United invests in these partnerships to either realize tax credits on its consolidated federal income tax return or for purposes of earning a return on its investment. These partnerships are considered VIEs as the limited partners lack a controlling financial interest in the entities through their inability to make decisions that have a significant effect on the operations and success of the partnerships. These partnerships are not consolidated as United is not deemed to be the primary beneficiary. At December 31, 2022 and 2021, United’s investment (maximum exposure to loss) in these low income housing and community development partnerships were $75,021,000 and $62,235,000, respectively, while related unfunded commitments were $77,143,000 and $69,894,000, respectively. As of December 31, 2022, United expects to recover its remaining investments through the use of the tax credits that are generated by the investments.

Segment Information

Segment Reporting [Abstract]
Segment Information	NOTE Y—SEGMENT INFORMATION United operates in two business segments: community banking and mortgage banking. Through its community banking segment, United offers a full range of products and services through various delivery channels. In particular, the community banking segment includes both commercial and consumer lending and provides customers with such products as commercial loans, real estate loans, business financing and consumer loans. In addition, this segment provides customers with several choices of deposit products including demand deposit accounts, savings accounts and certificates of deposit as well as investment and financial advisory services to businesses and individuals, including financial planning, retirement/estate planning, and investment management. The mortgage banking segment engages primarily in the origination and acquisition of residential mortgages for sale into the secondary market though United’s mortgage banking subsidiaries, George Mason and Crescent. Crescent may retain servicing rights on their mortgage loans sold. At certain times, Crescent may purchase or sell rights to service loans from or to third parties. These rights are known as mortgage servicing rights provide the owner with the contractual right to receive a stream of cash flows in exchange for performing specified mortgage servicing functions. The community banking segment provides the mortgage banking segment (George Mason and Crescent) with short-term funds to originate mortgage loans through a warehouse line of credit and charges the mortgage banking segment interest based on a Fed Funds target rate. These transactions are eliminated in the consolidation process. The Company does not have any operating segments other than those reported. The “Other” category consists of financial information not directly attributable to a specific segment, including interest income from investments and net securities gains or losses of parent companies and their non-banking non-segment Information about the reportable segments and reconciliation of this information to the consolidated financial statements at and for the years ended December 31, 2022, 2021 and 2020 is as follows: At and For the Year Ended December 31, 2022 (In thousands) Community Mortgage Other Intersegment Eliminations Consolidated Net interest income $ 890,575 $ 10,599 $ (13,274 ) $ 8,531 $ 896,431 Provision for credit losses 18,822 0 0 0 18,822 Other income 99,133 69,307 3,294 (18,473 ) 153,261 Other expense 472,813 88,983 3,233 (9,942 ) 555,087 Income taxes 100,758 (1,858 ) (2,744 ) 0 96,156 Net income (loss) $ 397,315 $ (7,219 ) $ (10,469 ) $ 0 $ 379,627 Total assets (liabilities) $ 29,106,176 $ 428,727 $ 58,971 $ (104,494 ) $ 29,489,380 Average assets (liabilities) 28,726,395 442,184 34,876 (129,607 ) 29,073,848 At and For the Year Ended December 31, 2021 (In thousands) Community Mortgage Other Intersegment Eliminations Consolidated Net interest income $ 731,305 $ 10,497 $ (8,378 ) $ 9,310 $ 742,734 Provision for credit losses (23,970 ) 0 0 0 (23,970 ) Other income 100,010 183,216 3,769 (8,867 ) 278,128 Other expense 443,493 138,508 (465 ) 443 581,979 Income taxes 84,715 11,275 (875 ) 0 95,115 Net income (loss) $ 327,077 $ 43,930 $ (3,269 ) $ 0 $ 367,738 Total assets (liabilities) $ 29,022,170 $ 691,642 $ 39,182 $ (424,092 ) $ 29,328,902 Average assets (liabilities) 26,910,956 659,105 27,445 (341,411 ) 27,256,095 At and For the Year Ended December 31, 2020 (In thousands) Community Mortgage Other Intersegment Eliminations Consolidated Net interest income $ 677,907 $ 8,853 $ (9,658 ) $ 12,671 $ 689,773 Provision for credit losses 106,562 0 0 0 106,562 Other income 90,121 276,185 730 (12,261 ) 354,775 Other expense 423,963 140,628 13,245 410 578,246 Income taxes 47,162 27,698 (4,143 ) 0 70,717 Net income (loss) $ 190,341 $ 116,712 $ (18,030 ) $ 0 $ 289,023 Total assets (liabilities) $ 25,892,396 $ 870,151 $ 31,623 $ (609,923 ) $ 26,184,247 Average assets (liabilities) 23,927,889 651,778 7,283 (449,880 ) 24,137,070

Accounting Policies [Abstract]
Nature of Operations	Nature of Operations:
Operating Segments	Operating Segments:
Basis of Presentation	Basis of Presentation: United determines whether it has a controlling financial interest in an entity by first evaluating whether the entity is a voting interest entity or a variable interest entity (“VIE”) under U.S. generally accepted accounting principles. Voting interest entities are entities in which the total equity investment at risk is sufficient to enable the entity to finance itself independently and provides the equity holders with the obligation to absorb losses, the right to receive residual returns and the right to make decisions about the entity’s activities. United consolidates voting interest entities in which it has all, or at least a majority of, the voting interest. As defined in applicable accounting standards, VIEs are entities that lack one or more of the characteristics of a voting interest entity. A controlling financial interest in a VIE is present when an enterprise has both the power to direct the activities of the VIE that most significantly impact the VIE’s economic performance and an obligation to absorb losses or the right to receive benefits that could potentially be significant to the VIE. The enterprise with a controlling financial interest, known as the primary beneficiary, consolidates the VIE. United’s wholly owned and indirect wholly owned statutory trust subsidiaries are VIEs for which United is not the primary beneficiary. Accordingly, its accounts are not included in United’s consolidated financial statements. The accounting and reporting policies of United conform with U.S. generally accepted accounting principles. In preparing the consolidated financial statements, management is required to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. To conform to the 2022 presentation, certain reclassifications have been made to prior period amounts, which had no impact on net income, comprehensive income or shareholders’ equity. In the opinion of management, all adjustments necessary for a fair presentation of financial position and results of operations have been made. Such adjustments are of a normal and recurring nature. In addition, $1,483,987,000 was reclassed from noninterest-bearing deposits to interest-bearing deposits on United’s Consolidated Balance Sheets for the period ended December 31, 2021 due to the nature of the underlying deposit accounts and a misclassification in the previous presentation. This reclassification did not impact any other amounts reported or disclosed in the consolidated financial statements. In the opinion of management, all adjustments necessary for a fair presentation of financial position and results of operations have been made.
Cash and Cash Equivalents	Cash and Cash Equivalents:
Debt securities	Debt securities HTM securities are accounted for at amortized cost, but the Company must have both the positive intent and the ability to hold those securities to maturity. There are very limited circumstances under which securities in the HTM category can be sold without jeopardizing the cost basis of accounting for the remainder of the securities in this category. Substantially all of the Company’s HTM debt securities are issued by state and political subdivisions (municipalities). As of December 31, 2022, United considers its HTM debt securities portfolio to be immaterial.

Securities Purchased Under Resale Agreements and Securities Sold Under Agreements to Repurchase	Securities Purchased Under Resale Agreements and Securities Sold Under Agreements to Repurchase:
Loans	Loans: A loan is categorized as a troubled debt restructuring (“TDR”) if a concession is granted and there is deterioration in the financial condition of the borrower. A loan classified as a TDR will generally retain such classification until the loan is paid in full. However, a one-to-four-family (“COVID-19”) COVID-19
Loans Acquired Through Transfer	Loans Acquired Through Transfer: Loans acquired in a business combination that have experienced more-than-insignificant deterioration in credit quality since origination are considered purchased credit deteriorated (“PCD”) loans. At the acquisition date, an estimate of expected credit losses is made for groups of PCD loans with similar risk characteristics and individual PCD loans without similar risk characteristics. This initial allowance for credit losses is allocated to individual PCD loans and added to the purchase price or acquisition date fair values to establish the initial amortized cost basis of the PCD loans. As the initial allowance for credit losses is added to the purchase price, there is no credit loss expense recognized upon acquisition of a PCD loan. Any difference between the unpaid principal balance of PCD loans and the amortized cost basis is considered to relate to noncredit factors and results in a discount or premium. Discounts and premiums are recognized through interest income on a level-yield method over the life of the loans. For loans and leases acquired after the adoption of ASC Topic 326, United will likely take several factors into consideration when determining if loans and leases meet the definition of PCD. ASC Topic 326 lists some, but not all, factors for consideration in the bifurcation of PCD versus non-PCD · Financial assets that are delinquent as of the acquisition date · Financial assets that have been downgraded since origination · Financial assets that have been placed on nonaccrual status
Loans Held for Sale	Loans Held for Sale: one-to-four Loans held for sale are recorded under the fair value option at a fair value measured using valuations from investors for loans with similar characteristics adjusted for the Company’s actual sales experience versus the investor’s indicated pricing.

Intangible Assets	Intangible Assets: one ten-year , , more-likely-than-not , 000 ,000
Mortgage Servicing Rights, Fees and Costs	Mortgage Servicing Rights, Fees and Costs: MSRs are amortized in proportion to, and over the period of, estimated net servicing income. The amortization of the MSRs is analyzed periodically and is adjusted to reflect changes in prepayment rates and other estimates. The Company evaluates potential impairment of MSRs based on the difference between the carrying amount and current estimated fair value of the servicing rights. In determining impairment, the Company aggregates all servicing rights and stratifies them into tranches based on predominant risk characteristics. If impairment exists, a valuation allowance is established for any excess of amortized cost over the current estimated fair value by a charge to income. If the Company later determines that all or a portion of the impairment no longer exists for a particular tranche, a reduction of the allowance may be recorded as an increase to income.
Accrued interest receivable	Accrued Interest Receivable • Presenting accrued interest receivable balances separately from their underlying instruments within the consolidated statements of financial condition. • Excluding accrued interest receivable that is included in the amortized cost of financing receivables from related disclosure requirements. • Continuing our policy to write off accrued interest receivable by reversing interest income in cases where the Company does not reasonably expect to receive payment. • Generally, not measuring an allowance for credit losses for accrued interest receivable due to the Company’s policy of writing off uncollectible accrued interest receivable balances in a timely manner. However, due to loan interest payment deferrals on certain loans and leases granted by United under the CARES Act, United assessed the collectability of the accrued interest receivables on these deferring loans and leases. As a result of this assessment, United did not record an allowance for credit losses for accrued interest receivables not expected to be collected as of December 31, 2022 as compared to an allowance for credit losses of $8,000 as of December 31, 2021
Revenue Recognition	Revenue Recognition Descriptions of our revenue-generating activities that are within the scope of ASC Topic 606, which are presented in our Consolidated Statements of Income as components of Other Income are discussed below. There are no significant judgements relating to the amount and timing of revenue recognition for those revenue streams under the scope of ASC Topic 606. Fees from Trust Services Revenue from trust services primarily is comprised of fees earned from the management and administration of trusts and other customer assets. Trust services include custody of assets, investment management, escrow services, and similar fiduciary activities. The Company’s performance obligation is generally satisfied over time and the resulting fees are recognized monthly, based upon the month-end Fees from Brokerage Services Revenue from brokerage services are recorded as the income is earned at the time the related service is performed. In return for such services, the Company charges a commission for the sales of various securities products primarily consisting of investment company shares, annuity products, and corporate debt and equity securities, for its selling and administrative efforts. For account supervision, advisory and administrative services, revenue is recognized over a period of time as earned based on customer account balances and activity. Fees from Deposit Services Service charges on deposit accounts consist of account analysis fees (i.e., net fees earned on analyzed business and public checking accounts), monthly service fees, check orders, ATM activity fees, debit card fees, and other deposit account related fees. Revenue is recognized when our performance obligation is completed which is generally monthly for account maintenance services or when a transaction has been completed (ATM or debit card activity).

Income Taxes	Income Taxes: more-likely-than-not For uncertain income tax positions, United records a liability based on a recognition threshold of more-likely-than-not,
Derivative Financial Instruments	Derivative Financial Instruments: Derivative instruments designated in a hedge relationship to mitigate exposure to changes in the fair value of an asset, liability, or firm commitment attributable to a particular risk, such as interest rate risk, are considered fair value hedges. Derivative instruments designated in a hedge relationship to mitigate exposure to variability in expected future cash flows, or other types of forecasted transactions, are considered cash flow hedges. For a fair value hedge, the fair value of the interest rate swap is recognized on the balance sheet as either a freestanding asset or liability with a corresponding adjustment to the hedged financial instrument. Subsequent adjustments due to changes in the fair value of a derivative that qualifies as a fair value hedge are offset in current period earnings either in interest income or interest expense depending on the nature of the hedged financial instrument. For a cash flow hedge, the fair value of the interest rate swap is recognized on the balance sheet as either a freestanding asset or liability with a corresponding adjustment to accumulated other comprehensive income within shareholders’ equity, net of tax. Subsequent adjustments due to changes in the fair value of a derivative that qualifies as a cash flow hedge are offset to accumulated other comprehensive income, net of tax and reclassified into earnings in the same line associated with the forecasted transaction when the forecasted transaction affects earnings. Fair value hedges may be eligible for offset on the consolidated balance sheets because they are subject to master netting arrangements or similar agreements. United has elected not to offset the assets and liabilities subject to such arrangements on the consolidated financial statements. At inception of a hedge relationship, United formally documents the hedged item, the particular risk management objective, the nature of the risk being hedged, the derivative being used, how effectiveness of the hedge will be assessed and how the ineffectiveness of the hedge will be measured. United also assesses hedge effectiveness at inception and on an ongoing basis using regression analysis. Hedge ineffectiveness is measured by using the change in fair value method. The change in fair value method compares the change in the fair value of the hedging derivative to the change in the fair value of the hedged exposure, attributable to changes in the benchmark rate. United through its mortgage banking subsidiaries enters into interest rate lock commitments to finance residential mortgage loans with its customers. These commitments, which contain fixed expiration dates, offer the borrower an interest rate guarantee provided the loan meets underwriting guidelines and closes within the timeframe established by United. Interest rate risk arises on these commitments and subsequently closed loans if interest rates change between the time of the interest rate lock and the delivery of the loan to the investor. Market risk on interest rate lock commitments and mortgage loans held for sale is managed using corresponding forward mortgage loan sales contracts. United is a party to these forward mortgage loan sales contracts to sell loans with servicing either released or retained and short sales of mortgage-backed securities. When the interest rate is locked with the borrower, the rate lock commitment, forward sale agreement, and mortgage-backed security position are undesignated derivatives and marked to fair value through earnings. The fair value of the rate lock derivative is measured using valuations from investors for loans with similar characteristics as well as considering the probability of the loan closing (i.e. the “pull-through” rate) with some adjusted for the Company’s actual sales experience versus the investor’s indicated pricing. Fair values of TBA mortgage-backed securities are measured using valuations from investors for mortgage-backed securities with similar characteristics. Income from mortgage banking activities includes the gain recognized for the period presented and associated elements of fair value. United is subject to the Dodd-Frank Act clearing requirement for eligible derivatives. United has executed and cleared eligible derivatives through the London Clearing House (“LCH”). Variation margin at the LCH is distinguished as settled-to-market collateralized-to-market.

Fair Value Measurements	Fair Value Measurements ASC Topic 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 United’s market assumptions. The three levels of the fair value hierarchy 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 market. Level 3 - Valuation is based on model-based techniques that use one or more significant inputs or assumptions that are unobservable in the market. When determining the fair value measurements for assets and liabilities, United looks to active and observable markets to price identical assets or liabilities whenever possible and classifies such items in Level 1. When identical assets and liabilities are not traded in active markets, United looks to market observable data for similar assets and liabilities and classifies such items as Level 2. Nevertheless, certain assets and liabilities are not actively traded in observable markets and United must use alternative valuation techniques using unobservable inputs to determine a fair value and classifies such items as Level 3. For assets and liabilities that are not actively traded, the fair value measurement is based primarily upon estimates that require significant judgment. Therefore, the results may not be realized in an actual sale or immediate settlement of the asset or liability. Additionally, there are inherent weaknesses in any calculation technique, and changes in the underlying assumptions used, including discount rates and estimates of future cash flows, could significantly affect the results of current or future values. The level within the fair value hierarchy is based on the lowest level of input that is significant in the fair value measurement.
