Summary of Significant Accounting Policies (Policies)	12 Months Ended
Dec. 31, 2021
Accounting Policies [Abstract]
Basis of accounting	The accounting principles followed by United and the methods of applying these principles conform with GAAP and with general practices within the banking industry. The following is a description of the significant policies.
Organization and Basis of Presentation	Organization and Basis of Presentation The Holding Company is a bank holding company under the BHC Act and, as of July 1, 2021, a financial holding company under the GLB Act. Financial holding company status allows for engagement in a broader range of financial activities. Prior to that the Holding Company was a bank holding company. The Holding Company’s principal business is conducted by its wholly-owned commercial bank subsidiary, United Community Bank. United is subject to regulation under the BHC Act. The consolidated financial statements include the accounts of the Holding Company, the Bank and other wholly-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation. Effective July 1, 2021, the Bank moved its headquarters from Blairsville, Georgia to Greenville, South Carolina and became a South Carolina state-chartered bank subject to examination and reporting requirements of the SCBFI. Prior to that date, the Bank was a Georgia state-chartered bank subject to examination and reporting requirements of the GADBF. The Bank serves both rural and metropolitan markets in Georgia, South Carolina, North Carolina, Tennessee and Florida and provides a full range of banking services. The Bank is insured by and subject to the regulation of the FDIC.
Use of Estimates	Use of Estimates In preparing the consolidated financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the dates of the balance sheet and revenue and expenses for the years then ended. Actual results could differ significantly from those estimates. Material estimates that are particularly susceptible to significant change are the determination of the ACL, the valuation of acquired loans, the valuation of real estate acquired in connection with foreclosures or in satisfaction of loans, the valuation of goodwill and separately identifiable intangible assets associated with mergers and acquisitions, and the valuation of deferred tax assets.
Operating Segments	Operating Segments Operating segments are components of a business about which separate financial information is available and evaluated regularly by the chief operating decision maker in deciding how to allocate resources and assessing performance. Public companies are required to report certain financial information about operating segments in interim and annual financial statements. United’s community banking operations are divided among geographic regions and local community banks within those regions. Those regions and banks have similar economic characteristics and are therefore considered to be one operating segment. Additionally, management assessed other operating units to determine if they should be classified and reported as segments, including Mortgage, Wealth Management and Commercial Banking Solutions. Qualitatively, these business units are primarily operating in the same geographic footprint as the community banks and face many of the same customers as the community banks. While the chief operating decision maker does have some limited production information for these entities, that information is not complete since it does not include a full allocation of revenue, costs and capital from key corporate functions. The business units are currently viewed more as a product line extension of the community banks. However, management will continue to evaluate these business units for separate reporting as facts and circumstances change. Based on this analysis, United concluded that it has one operating and reportable segment.
Cash and Cash Equivalents	Cash and Cash EquivalentsCash equivalents include amounts due from banks, interest-bearing deposits in banks, federal funds sold, commercial paper, reverse repurchase agreements and short-term investments and are carried at cost. Federal funds are generally sold for one-day periods, interest-bearing deposits in banks are available on demand and commercial paper investments and reverse repurchase agreements mature within a period of less than 90 days.
Investment Securities	Investment Securities Debt Securities: Debt securities are classified as HTM and carried at amortized cost when management has the positive intent and ability to hold them to maturity. Debt securities are classified as AFS when they may be sold before maturity. AFS securities are carried at fair value, with unrealized holding gains and losses reported in other comprehensive income, net of tax. Interest income includes amortization of purchase premiums or discounts. Premiums and discounts on securities are generally amortized or accreted on the level-yield method without anticipating prepayments, except for mortgage-backed securities where prepayments are anticipated. Premiums on callable debt securities are amortized to their earliest call date. Gains and losses on sales are recorded on the trade date and determined using the specific identification method. Transfers of securities between categories are recorded at fair value at the date of transfer. Unrealized holding gains or losses associated with transfers of securities from AFS to HTM are included in the balance of AOCI in the consolidated balance sheets. These unrealized holding gains or losses are amortized/accreted into income over the remaining life of the security as an adjustment to the yield in a manner consistent with the amortization or accretion of the original purchase premium or discount on the associated security. A debt security is placed on nonaccrual status at the time any principal or interest payments become 90 days delinquent. Interest accrued but not received for a security placed on nonaccrual is reversed against interest income. Equity securities: Equity securities are included in other assets on the consolidated balance sheets. Those with readily determinable fair values are carried at fair value with changes in fair value recognized in net income. Those without readily determinable fair values include, among others, FHLB stock held to meet FHLB requirements related to outstanding advances and CRA equity investments, including those where the returns are primarily derived from LIHTC. FHLB stock, which totaled $9.23 million at December 31, 2021, is accounted for using the cost method of accounting. LIHTC investments are accounted for using the proportional amortization method of accounting for qualified affordable housing investments which results in the amortization being reported as a component of income tax expense. Obligations related to unfunded commitments for LIHTC investments are reported in other liabilities. Other CRA investments are accounted for using the equity method of accounting. As conditions warrant, management reviews investments for impairment and adjusts the carrying value of the investment if it is deemed to be impaired.
ACL - Held-to-Maturity Securities, Available-For-Sale Securities, and Off-Balance Sheet Credit Exposures	United implemented CECL upon adoption of ASC 326 on January 1, 2020. The CECL framework requires an estimate of expected credit losses for the remaining estimated life of the financial asset using historical experience, current conditions, and reasonable and supportable forecasts. The following discussion provides a description of the methodology applied to calculate the ACL under CECL. Prior to the adoption of ASC 326, management evaluated securities for other-than-temporary impairment at least on a quarterly basis, and more frequently when economic or market concerns warranted such evaluation. ACL - HTM Debt Securities: Management measures current expected credit losses on HTM debt securities on a collective basis by major security type. The estimate of current expected credit losses considers historical credit loss information that is adjusted for current conditions and reasonable and supportable forecasts. Management classifies the HTM portfolio into the following major security types: U.S. Treasuries, U.S. Government agencies and GSEs, state and political subdivisions, residential mortgage-backed, agency and GSEs, commercial mortgage-backed, agency and GSEs and supranational entities. Accrued interest receivable on HTM debt is excluded from the estimate of credit losses. All of the residential and commercial mortgage-backed securities held by United as HTM are issued by U.S. Government agencies and GSEs. These securities are either explicitly or implicitly guaranteed by the U.S. government, are highly rated by major rating agencies and have a long history of no credit losses. The state and political subdivision securities are highly rated by major rating agencies. ACL - AFS Debt Securities: For AFS debt securities in an unrealized loss position, United first assesses whether it intends to sell, or whether it is more likely than not that it will be required to sell the security before recovery of its amortized cost basis. If either of the criteria regarding intent or requirement to sell is met, the security's amortized cost basis is written down to fair value through income. For AFS debt securities that do not meet the aforementioned criteria, United evaluates whether the decline in fair value has resulted from credit losses or other factors. In making this assessment, management considers the extent to which fair value is less than amortized cost, any changes to the rating of the security by a rating agency, and adverse conditions specifically related to the security, among other factors. If this assessment indicates that a credit loss exists, the present value of cash flows expected to be collected from the security are compared to the amortized cost basis of the security. If the present value of cash flows expected to be collected is less than the amortized cost basis, a credit loss exists and an ACL is recorded for the credit loss, limited by the amount that the fair value is less than the amortized cost basis. Any amount of unrealized loss that has not been recorded through an ACL is recognized in other comprehensive income. Accrued interest receivable on AFS debt securities is excluded from the estimate of credit losses. Changes in the ACL are recorded as provision for (or reversal of) credit loss expense. Losses are charged against the ACL 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.ACL - Off-Balance Sheet Credit Exposures Management estimates expected credit losses on commitments to extend credit over the contractual period during which United is exposed to credit risk on the underlying commitments. The ACL on off-balance sheet credit exposures is adjusted as a provision for credit loss expense. The estimate includes consideration of the likelihood that funding will occur and an estimate of expected credit losses on commitments expected to be funded over its estimated life. The ACL is calculated using the same aggregate reserve rates calculated for the funded portion of loans at the portfolio level applied to the amount of commitments expected to fund.
Loans Held for Sale	Loans Held for SaleUnited has elected the fair value option for mortgage loans held for sale in order to reduce certain timing differences and match changes in fair values of the loans with changes in the fair value of derivative instruments used to economically hedge them.
Loans and Leases	Loans and Leases Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are reported at amortized cost. Amortized cost is the principal balance outstanding, net of purchase premiums and discounts and deferred fees and costs. Interest income is accrued on the unpaid principal balance. Loan origination fees, net of certain direct origination costs, are deferred and recognized in interest income over the life of the loan. Equipment Financing Lease Receivables: Equipment financing lease receivables, which are classified as sales-type or direct financing leases, are recorded as the sum of the future minimum lease payments, initial deferred costs and, if applicable, estimated or contractual residual values less unearned income and security deposits. For lease receivables with a residual value, the determination of such value is derived from a variety of sources including equipment valuation services, appraisals, and publicly available market data on recent sales transactions on similar equipment. The length of time until contract termination, the cyclical nature of equipment values and the limited marketplace for re-sale of certain leased assets are important variables considered in making this determination. Interest income, which is included in loan interest revenue in the consolidated statements of income, is recognized as earned using the effective interest method. Direct fees and costs associated with the origination of leases are deferred and included as a component of equipment financing receivables. Net deferred fees or costs are recognized as an adjustment to interest income over the contractual life of the lease using the effective interest method. These lease agreements may include options to renew and for the lessee to purchase the leased equipment at the end of the lease term. United excludes sales taxes from consideration in these lease contracts. PCD Loans (CECL): In acquisitions, United may acquire loans, some of which have experienced more than insignificant credit deterioration since origination. In those cases, United will consider internal loan grades, delinquency status and other relevant factors in assessing whether purchased loans are PCD. PCD loans are recorded at their fair value at the acquisition date. An initial ACL is determined using the same methodology as other loans held for investment and recognized as an adjustment to the acquisition price of the asset; thus, the sum of the loan's purchase price and ACL becomes its initial amortized cost basis. The difference between the initial amortized cost basis and the par value of the loan is a noncredit discount or premium, which is amortized into interest income over the life of the loan. Subsequent to initial recognition, PCD loans are subject to the same interest income recognition and impairment model as non-PCD loans, with changes to the ACL recorded through provision expense. Nonaccrual Loans: The accrual of interest is generally discontinued when a loan becomes 90 days past due or when management believes, after considering economic and business conditions and collection efforts, that the principal or interest will not be collectable in the normal course of business. A loan may continue to accrue interest after 90 days if it is well collateralized and in the process of collection. Past due status is based on contractual terms of the loan. During 2020 and 2021, United granted loan payment deferrals in accordance with the CARES Act and interagency guidance for certain borrowers experiencing temporary cash flow shortages as a result of the COVID-19 pandemic. During the temporary payment deferral period, these loans are not considered past due. All interest accrued but not received for loans placed on nonaccrual is reversed against interest income. Interest received on such loans is accounted for using the cost-recovery method, until qualifying for return to accrual. Under the cost-recovery method, interest payments are reflected as a reduction of the carrying amount of the loan and interest income is not recognized until the loan balance is reduced to zero. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current, there is a sustained period of repayment performance and future payments are reasonably assured. TDRs: A loan for which the terms have been modified resulting in a more than insignificant concession, and for which the borrower is experiencing financial difficulties, is generally considered to be a TDR. Modified terms that result in a TDR include one or a combination of the following: a reduction of the stated interest rate of the loan, an extension of the amortization period that would not otherwise be considered in the current market for new debt with similar risk characteristics; a restructuring of the borrower’s debt into an “A/B note structure” in which the A note would fall within the borrower’s ability to pay and the remainder would be included in the B note; a mandated bankruptcy restructuring; or interest-only payment terms greater than 90 days where the borrower is unable to amortize the loan. Collateral dependent TDRs that subsequently default or are placed on nonaccrual are charged down to the fair value of the collateral consistent with United’s policy for nonaccrual loans. In accordance with the CARES Act, United implemented loan modification programs in response to the COVID-19 pandemic in order to provide borrowers with flexibility with respect to repayment terms. These loan modifications were not considered TDRs to the extent that the borrower was impacted by the COVID-19 pandemic and was not more than 30 days past due at December 31, 2019, or in certain circumstances, at the time that the COVID-19 loan modification program was implemented, unless the loan was previously classified as a TDR.
Concentration of Credit Risk	Concentration of Credit Risk: Most of United’s business activity is with customers located within the markets where it has banking operations. Therefore, United’s exposure to credit risk is significantly affected by changes in the economy within its markets. Approximately 73% of United’s loan portfolio is secured by real estate and is therefore susceptible to changes in real estate valuations.
ACL - Loans	ACL- Loans United implemented CECL upon adoption of ASC 326 on January 1, 2020. The CECL framework requires an estimate of expected credit losses for the remaining estimated life of the financial asset using historical experience, current conditions, and reasonable and supportable forecasts. The following discussion provides a description of the methodology applied to calculate the ACL under CECL. The Incurred Loss method was utilized in periods prior to 2020 and is outlined in detail in our previously filed reports on Form 10-K. The ACL is a valuation account that is deducted from the loans' amortized cost basis to present the net amount expected to be collected on the loans. Loans are charged off against the ACL when management believes the uncollectibility of a loan balance is confirmed. Accrued interest receivable is excluded from the estimate of credit losses. Management determines the ACL balance using relevant available information from internal and external sources, relating to past events, current conditions, and reasonable and supportable forecasts. Historical credit behaviors along with model judgments provide the basis for the estimation of expected credit losses. Adjustments to modeled loss estimates may be made for differences in current loan-specific risk characteristics such as differences in underwriting standards, portfolio mix, delinquency level, or term as well as for changes in environmental conditions, such as changes in economic conditions, property values, or other relevant factors. For the majority of loans and leases the ACL is calculated using a discounted cash flow methodology applied at a loan level with a one-year reasonable and supportable forecast period and a two-year straight-line reversion period. The ACL-loans is measured on a collective basis when similar risk characteristics exist. United has identified the following portfolio segments and calculates the ACL for each using a discounted cash flow methodology at the loan level, with loss rates, prepayment assumptions and curtailment assumptions driven by each loan’s collateral type: Owner occupied commercial real estate - Loans in this category are susceptible to business failure and general economic conditions. Income producing commercial real estate - Common risks for this loan category are declines in general economic conditions, declines in real estate value, declines in occupancy rates, and lack of suitable alternative use for the property. Commercial & industrial - Risks to this loan category include the inability to monitor the condition of the collateral, which often consists of inventory, accounts receivable and other non-real estate assets. Equipment and inventory obsolescence can also pose a risk. Declines in general economic conditions and other events can cause cash flows to fall to levels insufficient to service debt. Commercial construction - Risks common to commercial construction loans are cost overruns, changes in market demand for property, inadequate long-term financing arrangements and declines in real estate values. Equipment financing - Risks associated with equipment financing are similar to those described for commercial and industrial loans, including general economic conditions, as well as appropriate lien priority on equipment, equipment obsolescence and the general mobility of the collateral. Residential mortgage - Residential mortgage loans are susceptible to weakening general economic conditions, increases in unemployment rates and declining real estate values. HELOC - Risks common to home equity lines of credit are general economic conditions, including an increase in unemployment rates, and declining real estate values that reduce or eliminate the borrower’s home equity. Residential construction - Residential construction loans are susceptible to the same risks as residential mortgage loans. Changes in market demand for property lead to longer marketing times resulting in higher carrying costs and declining values. Consumer - Risks common to consumer direct loans include unemployment and changes in local economic conditions as well as the inability to monitor collateral consisting of personal property. 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, expected credit losses are based on the fair value of the collateral at the reporting date, adjusted for selling costs as appropriate. When the discounted cash flow method is used to determine the ACL, management adjusts the effective interest rate used to discount expected cash flows to incorporate expected prepayments. The ACL on a TDR is measured using the same method as all other loans held for investment, except that the original interest rate is used to discount the expected cash flows, not the rate specified within the restructuring. Determining the Contractual Term: Expected credit losses are estimated over the contractual term of the loans, adjusted for expected prepayments when appropriate. The contractual term excludes expected extensions, renewals, and modifications unless either of the following applies: management has a reasonable expectation at the reporting date that a TDR will be executed with an individual borrower or the extension or renewal options are included in the original or modified contract at the reporting date and are not unconditionally cancellable by United.
Premises and Equipment	Premises and Equipment Premises and equipment are stated at cost less accumulated depreciation. Depreciation is computed primarily using the straight line method over the estimated useful lives of the related assets. Costs incurred for maintenance and repairs are expensed as incurred. The range of estimated useful lives for buildings and improvements is 10 to 40 years, for land improvements, 10 years, and for furniture and equipment, 3 to 10 years. United periodically reviews the carrying value of premises and equipment for impairment whenever events or circumstances indicate that the carrying amount of such assets may not be fully recoverable.
Foreclosed Properties (Other Real Estate Owned)	Foreclosed Properties (Other Real Estate Owned)Foreclosed property is initially recorded at fair value, less cost to sell. If the fair value, less cost to sell at the time of foreclosure is less than the loan balance, the deficiency is recorded as a loan charge-off against the ACL. If the fair value, less cost to sell, of the foreclosed property decreases during the holding period, a valuation allowance is established with a charge to operating expenses. When the foreclosed property is sold, a gain or loss is recognized on the sale for the difference between the sales proceeds and the carrying amount of the property.
Goodwill and Other Intangible Assets	Goodwill and Other Intangible Assets Goodwill is an asset representing the future economic benefits from other assets acquired that are not individually identified and separately recognized. Goodwill is measured as the excess of the consideration transferred, net of the fair value of identifiable assets acquired and liabilities assumed at the acquisition date. Goodwill is not amortized, but instead is tested for impairment annually or more frequently if events or circumstances exist that indicate a goodwill impairment test should be performed. Other intangible assets, which are initially recorded at fair value, consist of core deposit and customer list intangibles resulting from acquisitions. Core deposit intangible assets are amortized over their estimated useful lives using the sum-of-the-years-digits method. Customer list intangibles are amortized over their estimated useful lives using the straight-line method. Management evaluates other intangible assets for impairment whenever events or changes in circumstances indicate the carrying amount of the asset may not be recoverable.
Transfers of Financial Assets	Transfers of Financial Assets Transfers of financial assets are accounted for as sales when control over the assets has been relinquished. Control over transferred assets is deemed to be surrendered when the assets have been isolated from United, the transferee obtains the right, free of conditions that constrain it from taking advantage of that right, to pledge or exchange the transferred assets and United does not maintain effective control over the transferred assets through an agreement to repurchase them before maturity.
Servicing Rights	Servicing Rights United records a separate servicing asset for SBA loans, USDA loans, and residential mortgage loans when the loan is sold but servicing is retained. This asset represents the right to service the loans and receive a fee in compensation. Servicing assets are initially recorded at their fair value as a component of the sale proceeds. The fair value of the servicing assets is based on an analysis of discounted cash flows that incorporates estimates of (1) market servicing costs, (2) market-based prepayment rates, and (3) market profit margins. Servicing assets are included in other assets. United has elected to subsequently measure the servicing assets for government guaranteed loans and residential mortgage loans at fair value. The rate of prepayment of loans serviced is the most significant estimate involved in the measurement process. Estimates of prepayment rates are based on market expectations of future prepayment rates, industry trends, and other considerations. Actual prepayment rates will differ from those projected by management due to changes in a variety of economic factors, including prevailing interest rates and the availability of alternative financing sources to borrowers. If actual prepayments of the loans being serviced were to occur more quickly than projected, the carrying value of servicing assets might have to be written down through a charge to earnings in the current period. If actual prepayments of the loans being serviced were to occur more slowly than had been projected, the carrying value of servicing assets could increase, and servicing income would exceed previously projected amounts. United accounts for the servicing liabilities associated with sold equipment financing loans using the amortization method. Servicing liabilities are included in accrued expenses and other liabilities.
BOLI	BOLI United has purchased life insurance policies on certain key executives and members of management. United has also received life insurance policies on members of acquired bank management teams through acquisitions of other banks. BOLI is recorded at the amount that can be realized under the insurance contract at the balance sheet date, which is the cash surrender value adjusted for other changes or other amounts due that are probable at settlement.
Operating Leases	Operating Leases United records a ROU asset, included in other assets, and a related lease liability, included in other liabilities, for eligible operating leases for which it is the lessee, which include leases for land, buildings, and equipment. At lease commencement, United records the ROU asset and related lease liability based on the present value of lease payments over the lease term. Absent a readily determinable interest rate in the lease agreement, United utilizes the Bank’s incremental borrowing rate for secured borrowings as the discount rate used in the present value calculation. Payments related to these leases consist primarily of base rent and, in the case of building leases, additional operating costs associated with the leased property such as common area maintenance and utilities. In most cases these operating costs vary over the term of the lease, and therefore are classified as variable lease costs, which are recognized as incurred in the consolidated statement of income. In addition, certain operating leases include costs such as property taxes and insurance, which are recognized as incurred in the consolidated statement of income. Many of United’s operating leases contain renewal options, which are included in the measurement of the ROU asset and lease liability to the extent they are reasonably certain to be exercised. United also subleases and leases certain real estate properties to third parties under operating leases. United does not recognize a lease liability or ROU asset on the consolidated balance sheet related to short-term leases with a term of less than one year. Lease payments for short-term leases are recognized as expense over the lease term.
Loan Commitments and Related Financial Instruments	Loan Commitments and Related Financial Instruments Financial instruments include off-balance sheet credit instruments such as commitments to make loans and commercial letters of credit issued to meet customer financing needs. The face amount for these items represents the exposure to loss before considering customer collateral or ability to repay. Such financial instruments are recorded when they are funded.
Revenue from Contracts with Customers	Revenue from Contracts with Customers In addition to lending and related activities, United offers various services to customers that generate revenue, certain of which are governed by ASC Topic 606 Revenue from Contracts with Customers. United’s services that fall within the scope of this topic are presented within noninterest income and include service charges and fees, wealth management fees, and other transaction-based fees. Revenue is recognized when the transactions occur or as services are performed over primarily monthly or quarterly periods. Payment is typically received in the period the transactions occur. Fees may be fixed or, where applicable, based on a percentage of transaction size.
Income Taxes	Income Taxes DTAs and DTLs are recorded for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Future tax benefits are recognized to the extent that realization of such benefits is more likely than not. DTAs and DTLs are measured using enacted tax rates expected to apply to taxable income in the years in which the assets and liabilities are expected to be recovered or settled. The effect of a change in tax rates on DTAs and DTLs is recognized in income tax expense during the period that includes the enactment date. In the event the future tax consequences of differences between the financial reporting bases and the tax bases of assets and liabilities results in DTAs, an evaluation of the probability of being able to realize the future benefits indicated by such asset is required. A valuation allowance is provided for the portion of the DTA when it is more likely than not that some or all of the DTA will not be realized. In assessing the realizability of the DTAs, management considers the scheduled reversals of DTLs, projected future taxable earnings and prudent and feasible tax planning strategies. Management weighs both the positive and negative evidence, giving more weight to evidence that can be objectively verified. The income tax benefit or expense is the total of the current year income tax due or refundable and the change in DTAs and DTLs. A tax position is recognized as a benefit only if it is “more likely than not” that the tax position would be sustained in a tax examination, with a tax examination being presumed to occur. The amount recognized is the largest amount of tax benefit that is greater than 50 percent likely of being realized on examination. For tax positions not meeting the “more likely than not” test, no tax benefit is recorded. United recognizes interest and / or penalties related to income tax matters in income tax expense.
Derivative Instruments and Hedging Activities	Derivative Instruments and Hedging Activities United’s interest rate risk management strategy incorporates the use of derivative instruments to minimize fluctuations in net income that are caused by interest rate volatility. The objective is to manage interest rate sensitivity by modifying the repricing or maturity characteristics of certain balance sheet assets and liabilities so that net interest revenue and certain interest sensitive components of noninterest revenue are not, on a material basis, adversely affected by movements in interest rates. United views this strategy as a prudent management of interest rate risk, such that net income is not exposed to undue risk presented by changes in interest rates. In carrying out this part of its interest rate risk management strategy, management uses derivatives, primarily interest rate swaps. Interest rate swaps generally involve the exchange of fixed- and variable-rate interest payments between two parties, based on a common notional principal amount and maturity date. United has also occasionally used interest rate caps to serve as an economic macro hedge of exposure to rising interest rates. United originates certain residential mortgage loans with the intention of selling these loans. Between the time United enters into an interest-rate lock commitment to originate a residential mortgage loan that is to be held for sale and the time the loan is funded and eventually sold, the Company is subject to the risk of variability in market prices. United enters into forward sale agreements to mitigate risk and to protect the expected gain on the eventual loan sale. The commitments to originate residential mortgage loans and forward loan sales commitments are freestanding derivative instruments which are entered into as part of an economic hedging strategy to manage exposure related to mortgage loans held for sale. To accommodate customers, United enters into interest rate swaps, caps or collars with certain commercial loan customers, with offsetting positions to dealers under a back-to-back swap/cap/collar program. In addition, United occasionally enters into credit risk participation agreements with counterparty banks to accept a portion of the credit risk related to interest rate swaps. This allows customers to execute an interest rate swap with one bank while allowing for the distribution of the credit risk among participating members. Credit risk participation agreements arise when United contracts with other financial institutions, as a guarantor, to share credit risk associated with certain interest rate swaps. These agreements provide for reimbursement of losses resulting from a third party default on the underlying swap. These transactions are typically executed in conjunction with a participation in a loan with the same customer. Collateral used to support the credit risk for the underlying lending relationship is also available to offset the risk of the credit risk participation. United classifies its derivative financial instruments as either (1) a hedge of an exposure to changes in the fair value of a recorded asset or liability (“fair value hedge”), (2) a hedge of an exposure to changes in the cash flows of a recognized asset, liability or forecasted transaction (“cash flow hedge”), or (3) derivatives not designated as accounting hedges. Changes in the fair value of derivatives not designated as hedges are recognized in current period earnings. United has master netting agreements with the derivatives dealers with which it does business, but reflects gross assets and liabilities at fair value on the consolidated balance sheets. United assesses hedge effectiveness at inception and over the life of the hedge. Management documents, at inception, its analysis of actual and expected hedge effectiveness. This analysis includes techniques such as regression analysis and hypothetical derivatives to demonstrate that the hedge is expected to be highly effective in offsetting corresponding changes in the fair value or cash flows of the hedged item. At least quarterly thereafter, the terms of the hedging instrument and the hedged item are assessed to determine whether a material change has occurred relating to the hedge relationship. If it is determined that a change has occurred, a quantitative analysis as described will occur to determine whether the hedge is expected to be highly effective in offsetting future corresponding changes in the fair value or cash flows of the hedged item. For a qualifying fair value hedge, the changes in the value of derivatives are recognized in current period earnings along with the corresponding changes in the fair value of the designated hedged item attributable to the risk being hedged. For a qualifying cash flow hedge, the changes in the fair value of the derivatives that have been highly effective are recognized in other comprehensive income until the related cash flows from the hedged item are recognized in earnings. For fair value hedges and cash flow hedges, ineffectiveness is recognized in the same income statement line as interest accruals on the hedged item to the extent that changes in the value of the derivative instruments do not perfectly offset changes in the value of the hedged items. If the hedge ceases to be highly effective, United discontinues hedge accounting and recognizes the changes in fair value in current period earnings. If a derivative that qualifies as a fair value or cash flow hedge is terminated or the designation removed, the realized or then unrealized gain or loss is recognized into income over the life of the hedged item (fair value hedge) or over the time when the hedged item was forecasted to impact earnings (cash flow hedge). Immediate recognition in earnings is required upon sale or extinguishment of the hedged item (fair value hedge) or if it is probable that the hedged cash flows will not occur (cash flow hedge). By using derivative instruments, United is exposed to credit and market risk. If the counterparty fails to perform, credit risk is represented by the fair value gain in a derivative. When the fair value of a derivative contract is positive, this situation generally indicates that the counterparty is obligated to pay United, and, therefore, creates a repayment risk for United. When the fair value of a derivative contract is negative, United is obligated to pay the counterparty and, therefore, has no repayment risk. United minimizes the credit risk in non-customer derivative instruments by entering into transactions with high-quality counterparties that are reviewed periodically by management. United also requires non-customer counterparties to pledge cash as collateral to cover the net exposure. All new non-customer derivatives that can be cleared are cleared through a central clearinghouse, which reduces counterparty exposure. Derivative activities are monitored by the ALCO as part its oversight of asset/liability and treasury functions. The ALCO is responsible for implementing various hedging strategies that are developed through its analysis of data from financial simulation models and other internal and industry sources. The resulting hedging strategies are then incorporated into the overall interest-rate risk management process.
Acquisition Activities	Acquisition Activities United accounts for business combinations under the acquisition method of accounting. Assets acquired and liabilities assumed are measured and recorded at fair value at the date of acquisition, including identifiable intangible assets. If the fair value of net assets purchased exceeds the fair value of consideration paid, a bargain purchase gain is recognized at the date of acquisition. Conversely, if the consideration paid exceeds the fair value of the net assets acquired, goodwill is recognized at the acquisition date. Fair values are subject to refinement for a period not to exceed one year after the closing date of an acquisition as information relative to closing date fair values becomes available. Fair values for acquired loans are generally based on a discounted cash flow methodology that considers credit loss expectations, market interest rates and other market factors such as liquidity from the perspective of a market participant. Loans are grouped together according to similar characteristics and are generally treated in the aggregate when applying various valuation techniques. The probability of default, loss given default and prepayment assumptions are the key factors driving credit losses which are embedded into the estimated cash flows. These assumptions are informed by internal data on loan characteristics, historical loss experience, and current and forecasted economic conditions. The interest and liquidity component of the estimate is determined by discounting interest and principal cash flows through the expected life of each loan. The discount rates used for loans are based on current market rates for new originations of comparable loans and include adjustments for liquidity. The discount rate does not include a factor for credit losses as that has been included as a reduction to the estimated cash flows. For additional information about the accounting for purchased loans see PCD Loans (CECL) under the Loans and Leases section of this footnote. All identifiable intangible assets that are acquired in a business combination are recognized at fair value on the acquisition date. Identifiable intangible assets are recognized separately if they arise from contractual or other legal rights or if they are separable (i.e., capable of being sold, transferred, licensed, rented, or exchanged separately from the entity). Deposit liabilities and the related depositor relationship intangible assets may be exchanged in observable exchange transactions. As a result, the depositor relationship intangible asset is considered identifiable, because the separability criterion has been met.
Earnings Per Common Share	Earnings Per Common ShareBasic earnings per common share is net income available to common shareholders divided by the weighted average number of shares of common stock outstanding during the period. All outstanding unvested share-based payment awards that contain rights to nonforfeitable dividends are considered participating securities for this calculation. Additionally, shares issuable to participants in United’s deferred compensation plan are considered to be participating securities for purposes of calculating basic earnings per share. Accordingly, net income available to common shareholders is calculated pursuant to the two-class method, whereby net income after subtracting preferred stock dividends is allocated between common shareholders and participating securities. Diluted earnings per common share includes the dilutive effect of additional potential shares of common stock issuable under stock options, unvested restricted stock units without nonforfeitable rights to dividends, warrants and securities convertible into common stock.
Loss Contingencies	Loss ContingenciesLoss contingencies, including claims and legal actions arising in the ordinary course of business, are recorded as liabilities when the likelihood of loss is probable and an amount or range of loss can be reasonably estimated. Management does not believe there are such matters that will have a material effect on the financial statements.
Dividend Restrictions	Dividend RestrictionsBanking regulations require maintaining certain capital levels and may limit dividends paid by the Bank to the Holding Company or by the Holding Company to shareholders. As a South Carolina state-chartered bank, the Bank is permitted to pay a dividend of up to 100% of its current year earnings without requesting approval of the SCBFI, provided certain conditions are met. Prior to July 1, 2021, as a Georgia state-chartered bank, the Board could declare dividends from the Bank to the Holding Company out of retained earnings of up to fifty percent of the Bank’s net income from the previous year without notifying or seeking approval from the GADBF, provided certain conditions were met.
Fair Value of Financial Instruments	Fair Value of Financial InstrumentsFair values of financial instruments are estimated using relevant market information and other assumptions as more fully disclosed in Note 14. Fair value estimates involve uncertainties and matters of significant judgment regarding interest rates, credit risk, prepayments, and other factors, especially in the absence of broad markets for particular items. Changes in assumptions or in market conditions could significantly affect these estimates. Fair value measurements are determined based on the assumptions that market participants would use in pricing the asset or liability. As a basis for considering market participant assumptions in fair value measurements, United uses a fair value hierarchy that distinguishes between market participant assumptions based on market data obtained from sources independent of the reporting entity (observable inputs that are classified within Levels 1 and 2 of the hierarchy) and the reporting entity’s own assumptions about market participant assumptions (unobservable inputs classified within Level 3 of the hierarchy). United has processes in place to review the significant valuation inputs and to reassess how the instruments are classified in the valuation framework. Fair Value Hierarchy Level 1 Valuation is based upon quoted prices (unadjusted) in active markets for identical assets or liabilities that United has the ability to access. Level 2 Valuation is based upon quoted prices for similar assets and liabilities in active markets, as well as inputs that are observable for the asset or liability (other than quoted prices), such as interest rates, foreign exchange rates, and yield curves that are observable at commonly quoted intervals. Level 3 Valuation is generated from model-based techniques that use at least one significant assumption based on unobservable inputs for the asset or liability, which are typically based on an entity’s own assumptions, as there is little, if any, related market activity. In instances where the determination of the fair value measurement is based on inputs from different levels of the fair value hierarchy, the level in the fair value hierarchy within which the entire fair value measurement falls is based on the lowest level input that is significant to the fair value measurement in its entirety. United’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment, and considers factors specific to the asset or liability. The following is a description of the valuation methodologies used for assets and liabilities recorded at fair value. Investment Securities AFS debt securities and equity securities with readily determinable fair values are recorded at fair value on a recurring basis. Fair value measurement is based upon quoted prices, if available. If quoted prices are not available, fair values are measured using independent pricing models or other model-based valuation techniques such as the present value of future cash flows, adjusted for the security’s credit rating, prepayment assumptions and other factors such as credit loss assumptions. Level 1 securities include those traded on an active exchange, such as the New York Stock Exchange, U.S. Treasury securities that are traded by dealers or brokers in active over-the-counter markets and money market funds. Level 2 securities include mortgage-backed securities issued by government sponsored entities, municipal bonds, corporate debt securities and asset-backed securities and are valued based on observable inputs that include: quoted market prices for similar assets, quoted market prices that are not in an active market or other inputs that are observable in the market and can be corroborated by observable market data for substantially the full term of the securities. Securities classified as Level 3 include those traded in less liquid markets and are valued based on estimates obtained from broker-dealers that are not directly observable. Deferred Compensation Plan Assets and Liabilities Included in other assets in the consolidated balance sheets are assets related to employee deferred compensation plans. The assets associated with these plans are invested in mutual funds and classified as Level 1. Deferred compensation liabilities, also classified as Level 1, are carried at the fair value of the obligation to the employee, which mirrors the fair value of the invested assets and is included in other liabilities in the consolidated balance sheets. Mortgage Loans Held for Sale United has elected the fair value option for newly originated mortgage loans held for sale in order to reduce certain timing differences and better match changes in fair values of the loans with changes in the value of derivative instruments used to economically hedge them. The fair value of mortgage loans held for sale is determined using quoted prices for a similar asset, adjusted for specific attributes of that loan and are classified as Level 2. Derivative Financial Instruments United uses derivatives to manage interest rate risk. The valuation of these instruments is typically determined using widely accepted valuation techniques including discounted cash flow analysis on the expected cash flows of each derivative. This analysis reflects the contractual terms of the derivatives, including the period to maturity, and uses observable market-based inputs, including interest rate curves and implied volatilities. The fair values of interest rate swaps are determined using the market standard methodology of netting the discounted future fixed cash receipts and the discounted expected variable cash payments. The variable cash payments are based on an expectation of future interest rates (forward curves) derived from observable market interest rate curves. United also uses best effort and mandatory delivery forward loan sale commitments to hedge risk in its mortgage lending business. United incorporates credit valuation adjustments (“CVAs”) as necessary to appropriately reflect the respective counterparty’s nonperformance risk in the fair value measurements. In adjusting the fair value of its derivative contracts for the effect of nonperformance risk, United has considered the effect of netting and any applicable credit enhancements, such as collateral postings, thresholds and guarantees. Management has determined that the majority of the inputs used to value its derivatives fall within Level 2 of the fair value hierarchy. However, the CVAs associated with these derivatives utilize Level 3 inputs, such as estimates of current credit spreads, to evaluate the likelihood of default by itself and its counterparties. Generally, management’s assessment of the significance of the CVAs has indicated that they are not a significant input to the overall valuation of the derivatives. In cases where management’s assessment indicates that the CVA is a significant input, the related derivative is disclosed as a Level 3 value. Other derivatives classified as Level 3 include structured derivatives for which broker quotes, used as a key valuation input, were not observable. Risk participation agreements are classified as Level 3 instruments due to the incorporation of significant Level 3 inputs used to evaluate the probability of funding and the likelihood of customer default. Interest rate lock commitments, which relate to mortgage loan commitments, are categorized as Level 3 instruments as the fair value of these instruments is based on unobservable inputs for commitments that United does not expect to fund. Servicing Rights for Residential Mortgage and SBA/USDA Loans United recognizes servicing rights upon the sale of residential mortgage and SBA/USDA loans sold with servicing retained. Management has elected to carry these assets at fair value. Given the nature of the assets, the key valuation inputs are unobservable and management considers these Level 3 assets. For disclosure regarding the fair value of servicing rights, see Note 10.
Stock-Based Compensation	Stock-Based CompensationUnited uses the fair value method of recognizing expense for stock-based compensation based on the fair value of option and restricted stock unit awards at the date of grant. United accounts for forfeitures as they occur.
Accounting Standards Updates and Recently Adopted Standards	Recently Adopted Standards In August 2021, the FASB issued ASU No. 2021-06, Presentation of Financial Statements (Topic 205), Financial Services - Depository and Lending (Topic 942) and Financial Services - Investment Companies (Topic 946): August 2021 Amendments to SEC Paragraphs Pursuant to SEC Final Rule Releases No. 33-10786, Amendments to Financial Disclosures about Acquired and Disposed Businesses, and No. 33-10835, Update of Statistical Disclosures for Bank and Savings and Loan Registrants. Among other things, this update eliminates redundancies for items covered elsewhere in GAAP, such as loan category presentation. United adopted this update immediately, with no material impact on the consolidated financial statements. In October 2020, the FASB issued ASU No. 2020-10, Codification Improvements. In addition to consolidating existing disclosure guidance into a single codification section to reduce the likelihood of a required disclosure being missed, this update clarifies the application of select guidance in cases where the original guidance may have been unclear. United adopted this update as of January 1, 2021, with no material impact on the consolidated financial statements. In October 2020, the FASB issued ASU No. 2020-08, Codification Improvements to Subtopic 310-20, Receivables—Nonrefundable Fees and Other Costs. This update clarifies that an entity should reevaluate whether a callable debt security meets the criteria to adjust the amortization period of any related premium at each reporting period. United adopted this update as of January 1, 2021, with no material impact on the consolidated financial statements. In January 2020, the FASB issued ASU No. 2020-01, Investments—Equity Securities (Topic 321), Investments—Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815)—Clarifying the Interactions between Topic 321, Topic 323, and Topic 815 (a consensus of the Emerging Issues Task Force). This update clarifies whether an entity should consider observable transactions that require it to either apply or discontinue the equity method of accounting for the purposes of applying the measurement alternative and how to account for certain forward contracts and purchased options to purchase securities. United adopted this update as of January 1, 2021, with no material impact on the consolidated financial statements. In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes. This update removes several exceptions related to intraperiod tax allocation when there is a loss from continuing operations and income from other items, foreign subsidiaries becoming equity method investments and vice versa, and calculating income taxes in an interim period when a year-to-date loss exceeds the anticipated loss for the year. The guidance also amends requirements related to franchise tax that is partially based on income, a step up in the tax basis of goodwill, allocation of consolidated tax expense to a legal entity not subject to tax in its separate financial statements, the effects of enacted changes in tax laws and other minor codification improvements regarding employee stock ownership plans and investments in qualified affordable housing projects. United adopted this update as of January 1, 2021, with no material impact on the consolidated financial statements. In August 2018, the FASB issued ASU No. 2018-14, Compensation - Retirement Benefits - Defined Benefit Plans - General (Subtopic 715-20): Disclosure Framework - Changes to the Disclosure Requirements for Defined Benefit Plans. The update removes disclosures that are no longer considered cost beneficial, clarifies specific requirements of disclosures, and adds disclosure requirements identified as relevant. United adopted this update as of January 1, 2021, with no material impact on the consolidated financial statements. Accounting Standards Updates Not Yet Adopted as of December 31, 2021 In October 2021, the FASB issued ASU No. 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from contracts with Customers. The update requires that an acquiring entity apply the guidance from Revenue from Contracts with Customers (Topic 606) to recognize and measure contract assets and contract liabilities in a business combination, rather than fair value. For public entities, this guidance is effective for fiscal years beginning after December 15, 2022, with early adoption permitted, and requires prospective application. United does not expect the new guidance to have a material impact on the consolidated financial statements. In July 2021, the FASB issued ASU No. 2021-05, Leases (Topic 842): Lessors - Certain Leases with Variable Lease Payments. The update amends the lease classification requirements for lessors to align them with practice under the former lease accounting standard. Specifically, lessors should classify a lease with variable lease payments that do not depend on a reference index or rate as an operating lease if certain criteria are met. Adoption of this update as of January 1, 2022 did not have a material impact on the consolidated financial statements.

Summary of Significant Accounting Policies (Policies)

12 Months Ended

Dec. 31, 2021

The accounting principles followed by United and the methods of applying these principles conform with GAAP and with general practices within the banking industry. The following is a description of the significant policies.

Organization and Basis of Presentation

The Holding Company is a bank holding company under the BHC Act and, as of July 1, 2021, a financial holding company under the GLB Act. Financial holding company status allows for engagement in a broader range of financial activities. Prior to that the Holding Company was a bank holding company. The Holding Company’s principal business is conducted by its wholly-owned commercial bank subsidiary, United Community Bank. United is subject to regulation under the BHC Act. The consolidated financial statements include the accounts of the Holding Company, the Bank and other wholly-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation.

Effective July 1, 2021, the Bank moved its headquarters from Blairsville, Georgia to Greenville, South Carolina and became a South Carolina state-chartered bank subject to examination and reporting requirements of the SCBFI. Prior to that date, the Bank was a Georgia state-chartered bank subject to examination and reporting requirements of the GADBF. The Bank serves both rural and metropolitan markets in Georgia, South Carolina, North Carolina, Tennessee and Florida and provides a full range of banking services. The Bank is insured by and subject to the regulation of the FDIC.

Use of Estimates

In preparing the consolidated financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the dates of the balance sheet and revenue and expenses for the years then ended. Actual results could differ significantly from those estimates. Material estimates that are particularly susceptible to significant change are the determination of the ACL, the valuation of acquired loans, the valuation of real estate acquired in connection with foreclosures or in satisfaction of loans, the valuation of goodwill and separately identifiable intangible assets associated with mergers and acquisitions, and the valuation of deferred tax assets.

Operating Segments

Operating segments are components of a business about which separate financial information is available and evaluated regularly by the chief operating decision maker in deciding how to allocate resources and assessing performance. Public companies are required to report certain financial information about operating segments in interim and annual financial statements. United’s community banking operations are divided among geographic regions and local community banks within those regions. Those regions and banks have similar economic characteristics and are therefore considered to be one operating segment.

Additionally, management assessed other operating units to determine if they should be classified and reported as segments, including Mortgage, Wealth Management and Commercial Banking Solutions. Qualitatively, these business units are primarily operating in the same geographic footprint as the community banks and face many of the same customers as the community banks. While the chief operating decision maker does have some limited production information for these entities, that information is not complete since it does not include a full allocation of revenue, costs and capital from key corporate functions. The business units are currently viewed more as a product line extension of the community banks. However, management will continue to evaluate these business units for separate reporting as facts and circumstances change.

Based on this analysis, United concluded that it has one operating and reportable segment.

Cash and Cash Equivalents

Cash and Cash EquivalentsCash equivalents include amounts due from banks, interest-bearing deposits in banks, federal funds sold, commercial paper, reverse repurchase agreements and short-term investments and are carried at cost. Federal funds are generally sold for one-day periods, interest-bearing deposits in banks are available on demand and commercial paper investments and reverse repurchase agreements mature within a period of less than 90 days.

Investment Securities

Debt Securities: Debt securities are classified as HTM and carried at amortized cost when management has the positive intent and ability to hold them to maturity. Debt securities are classified as AFS when they may be sold before maturity. AFS securities are carried at fair value, with unrealized holding gains and losses reported in other comprehensive income, net of tax.

Interest income includes amortization of purchase premiums or discounts. Premiums and discounts on securities are generally amortized or accreted on the level-yield method without anticipating prepayments, except for mortgage-backed securities where prepayments are anticipated. Premiums on callable debt securities are amortized to their earliest call date. Gains and losses on sales are recorded on the trade date and determined using the specific identification method.

Transfers of securities between categories are recorded at fair value at the date of transfer. Unrealized holding gains or losses associated with transfers of securities from AFS to HTM are included in the balance of AOCI in the consolidated balance sheets. These unrealized holding gains or losses are amortized/accreted into income over the remaining life of the security as an adjustment to the yield in a manner consistent with the amortization or accretion of the original purchase premium or discount on the associated security.

A debt security is placed on nonaccrual status at the time any principal or interest payments become 90 days delinquent. Interest accrued but not received for a security placed on nonaccrual is reversed against interest income.

Equity securities: Equity securities are included in other assets on the consolidated balance sheets. Those with readily determinable fair values are carried at fair value with changes in fair value recognized in net income. Those without readily determinable fair values include, among others, FHLB stock held to meet FHLB requirements related to outstanding advances and CRA equity investments, including those where the returns are primarily derived from LIHTC. FHLB stock, which totaled $9.23 million at December 31, 2021, is accounted for using the cost method of accounting. LIHTC investments are accounted for using the proportional amortization method of accounting for qualified affordable housing investments which results in the amortization being reported as a component of income tax expense. Obligations related to unfunded commitments for LIHTC investments are reported in other liabilities. Other CRA investments are accounted for using the equity method of accounting. As conditions warrant, management reviews investments for impairment and adjusts the carrying value of the investment if it is deemed to be impaired.

ACL - Held-to-Maturity Securities, Available-For-Sale Securities, and Off-Balance Sheet Credit Exposures

United implemented CECL upon adoption of ASC 326 on January 1, 2020. The CECL framework requires an estimate of expected credit losses for the remaining estimated life of the financial asset using historical experience, current conditions, and reasonable and supportable forecasts. The following discussion provides a description of the methodology applied to calculate the ACL under CECL. Prior to the adoption of ASC 326, management evaluated securities for other-than-temporary impairment at least on a quarterly basis, and more frequently when economic or market concerns warranted such evaluation.

ACL - HTM Debt Securities: Management measures current expected credit losses on HTM debt securities on a collective basis by major security type. The estimate of current expected credit losses considers historical credit loss information that is adjusted for current conditions and reasonable and supportable forecasts. Management classifies the HTM portfolio into the following major security types: U.S. Treasuries, U.S. Government agencies and GSEs, state and political subdivisions, residential mortgage-backed, agency and GSEs, commercial mortgage-backed, agency and GSEs and supranational entities. Accrued interest receivable on HTM debt is excluded from the estimate of credit losses.

All of the residential and commercial mortgage-backed securities held by United as HTM are issued by U.S. Government agencies and GSEs. These securities are either explicitly or implicitly guaranteed by the U.S. government, are highly rated by major rating agencies and have a long history of no credit losses. The state and political subdivision securities are highly rated by major rating agencies.

ACL - AFS Debt Securities: For AFS debt securities in an unrealized loss position, United first assesses whether it intends to sell, or whether it is more likely than not that it will be required to sell the security before recovery of its amortized cost basis. If either of the criteria regarding intent or requirement to sell is met, the security's amortized cost basis is written down to fair value through income. For AFS debt securities that do not meet the aforementioned criteria, United evaluates whether the decline in fair value has resulted from credit losses or other factors. In making this assessment, management considers the extent to which fair value is less than amortized cost, any changes to the rating of the security by a rating agency, and adverse conditions specifically related to the security, among other factors. If this assessment indicates that a credit loss exists, the present value of cash flows expected to be collected from the security are compared to the amortized cost basis of the security. If the present value of cash flows expected to be collected is less than the amortized cost basis, a credit loss exists and an ACL is recorded for the credit loss, limited by the amount that the fair value is less than the amortized cost basis. Any amount of unrealized loss that has not been recorded through an ACL is recognized in other comprehensive income. Accrued interest receivable on AFS debt securities is excluded from the estimate of credit losses.

Changes in the ACL are recorded as provision for (or reversal of) credit loss expense. Losses are charged against the ACL 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.ACL - Off-Balance Sheet Credit Exposures Management estimates expected credit losses on commitments to extend credit over the contractual period during which United is exposed to credit risk on the underlying commitments. The ACL on off-balance sheet credit exposures is adjusted as a provision for credit loss expense. The estimate includes consideration of the likelihood that funding will occur and an estimate of expected credit losses on commitments expected to be funded over its estimated life. The ACL is calculated using the same aggregate reserve rates calculated for the funded portion of loans at the portfolio level applied to the amount of commitments expected to fund.

Loans Held for Sale

Loans Held for SaleUnited has elected the fair value option for mortgage loans held for sale in order to reduce certain timing differences and match changes in fair values of the loans with changes in the fair value of derivative instruments used to economically hedge them.

Loans and Leases

Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are reported at amortized cost. Amortized cost is the principal balance outstanding, net of purchase premiums and discounts and deferred fees and costs. Interest income is accrued on the unpaid principal balance. Loan origination fees, net of certain direct origination costs, are deferred and recognized in interest income over the life of the loan.

Equipment Financing Lease Receivables: Equipment financing lease receivables, which are classified as sales-type or direct financing leases, are recorded as the sum of the future minimum lease payments, initial deferred costs and, if applicable, estimated or contractual residual values less unearned income and security deposits. For lease receivables with a residual value, the determination of such value is derived from a variety of sources including equipment valuation services, appraisals, and publicly available market data on recent sales transactions on similar equipment. The length of time until contract termination, the cyclical nature of equipment values and the limited marketplace for re-sale of certain leased assets are important variables considered in making this determination. Interest income, which is included in loan interest revenue in the consolidated statements of income, is recognized as earned using the effective interest method. Direct fees and costs associated with the origination of leases are deferred and included as a component of equipment financing receivables. Net deferred fees or costs are recognized as an adjustment to interest income over the contractual life of the lease using the effective interest method. These lease agreements may include options to renew and for the lessee to purchase the leased equipment at the end of the lease term. United excludes sales taxes from consideration in these lease contracts.

PCD Loans (CECL): In acquisitions, United may acquire loans, some of which have experienced more than insignificant credit deterioration since origination. In those cases, United will consider internal loan grades, delinquency status and other relevant factors in assessing whether purchased loans are PCD. PCD loans are recorded at their fair value at the acquisition date. An initial ACL is determined using the same methodology as other loans held for investment and recognized as an adjustment to the acquisition price of the asset; thus, the sum of the loan's purchase price and ACL becomes its initial amortized cost basis. The difference between the initial amortized cost basis and the par value of the loan is a noncredit discount or premium, which is amortized into interest income over the life of the loan. Subsequent to initial recognition, PCD loans are subject to the same interest income recognition and impairment model as non-PCD loans, with changes to the ACL recorded through provision expense.

Nonaccrual Loans: The accrual of interest is generally discontinued when a loan becomes 90 days past due or when management believes, after considering economic and business conditions and collection efforts, that the principal or interest will not be collectable in the normal course of business. A loan may continue to accrue interest after 90 days if it is well collateralized and in the process of collection. Past due status is based on contractual terms of the loan. During 2020 and 2021, United granted loan payment deferrals in accordance with the CARES Act and interagency guidance for certain borrowers experiencing temporary cash flow shortages as a result of the COVID-19 pandemic. During the temporary payment deferral period, these loans are not considered past due.

All interest accrued but not received for loans placed on nonaccrual is reversed against interest income. Interest received on such loans is accounted for using the cost-recovery method, until qualifying for return to accrual. Under the cost-recovery method, interest payments are reflected as a reduction of the carrying amount of the loan and interest income is not recognized until the loan balance is reduced to zero. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current, there is a sustained period of repayment performance and future payments are reasonably assured.

TDRs: A loan for which the terms have been modified resulting in a more than insignificant concession, and for which the borrower is experiencing financial difficulties, is generally considered to be a TDR. Modified terms that result in a TDR include one or a combination of the following: a reduction of the stated interest rate of the loan, an extension of the amortization period

that would not otherwise be considered in the current market for new debt with similar risk characteristics; a restructuring of the borrower’s debt into an “A/B note structure” in which the A note would fall within the borrower’s ability to pay and the remainder would be included in the B note; a mandated bankruptcy restructuring; or interest-only payment terms greater than 90 days where the borrower is unable to amortize the loan.

Collateral dependent TDRs that subsequently default or are placed on nonaccrual are charged down to the fair value of the collateral consistent with United’s policy for nonaccrual loans.

In accordance with the CARES Act, United implemented loan modification programs in response to the COVID-19 pandemic in order to provide borrowers with flexibility with respect to repayment terms. These loan modifications were not considered TDRs to the extent that the borrower was impacted by the COVID-19 pandemic and was not more than 30 days past due at December 31, 2019, or in certain circumstances, at the time that the COVID-19 loan modification program was implemented, unless the loan was previously classified as a TDR.

Concentration of Credit Risk

Concentration of Credit Risk: Most of United’s business activity is with customers located within the markets where it has banking operations. Therefore, United’s exposure to credit risk is significantly affected by changes in the economy within its markets. Approximately 73% of United’s loan portfolio is secured by real estate and is therefore susceptible to changes in real estate valuations.

ACL - Loans

ACL- Loans

United implemented CECL upon adoption of ASC 326 on January 1, 2020. The CECL framework requires an estimate of expected credit losses for the remaining estimated life of the financial asset using historical experience, current conditions, and reasonable and supportable forecasts. The following discussion provides a description of the methodology applied to calculate the ACL under CECL. The Incurred Loss method was utilized in periods prior to 2020 and is outlined in detail in our previously filed reports on Form 10-K.

The ACL is a valuation account that is deducted from the loans' amortized cost basis to present the net amount expected to be collected on the loans. Loans are charged off against the ACL when management believes the uncollectibility of a loan balance is confirmed. Accrued interest receivable is excluded from the estimate of credit losses.

Management determines the ACL balance using relevant available information from internal and external sources, relating to past events, current conditions, and reasonable and supportable forecasts. Historical credit behaviors along with model judgments provide the basis for the estimation of expected credit losses. Adjustments to modeled loss estimates may be made for differences in current loan-specific risk characteristics such as differences in underwriting standards, portfolio mix, delinquency level, or term as well as for changes in environmental conditions, such as changes in economic conditions, property values, or other relevant factors. For the majority of loans and leases the ACL is calculated using a discounted cash flow methodology applied at a loan level with a one-year reasonable and supportable forecast period and a two-year straight-line reversion period.

The ACL-loans is measured on a collective basis when similar risk characteristics exist. United has identified the following portfolio segments and calculates the ACL for each using a discounted cash flow methodology at the loan level, with loss rates, prepayment assumptions and curtailment assumptions driven by each loan’s collateral type:

Owner occupied commercial real estate - Loans in this category are susceptible to business failure and general economic conditions.

Income producing commercial real estate - Common risks for this loan category are declines in general economic conditions, declines in real estate value, declines in occupancy rates, and lack of suitable alternative use for the property.

Commercial & industrial - Risks to this loan category include the inability to monitor the condition of the collateral, which often consists of inventory, accounts receivable and other non-real estate assets. Equipment and inventory obsolescence can also pose a risk. Declines in general economic conditions and other events can cause cash flows to fall to levels insufficient to service debt.

Commercial construction - Risks common to commercial construction loans are cost overruns, changes in market demand for property, inadequate long-term financing arrangements and declines in real estate values.

Equipment financing - Risks associated with equipment financing are similar to those described for commercial and industrial loans, including general economic conditions, as well as appropriate lien priority on equipment, equipment obsolescence and the general mobility of the collateral.

Residential mortgage - Residential mortgage loans are susceptible to weakening general economic conditions, increases in unemployment rates and declining real estate values.

HELOC - Risks common to home equity lines of credit are general economic conditions, including an increase in unemployment rates, and declining real estate values that reduce or eliminate the borrower’s home equity.

Residential construction - Residential construction loans are susceptible to the same risks as residential mortgage loans. Changes in market demand for property lead to longer marketing times resulting in higher carrying costs and declining values.

Consumer - Risks common to consumer direct loans include unemployment and changes in local economic conditions as well as the inability to monitor collateral consisting of personal property.

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, expected credit losses are based on the fair value of the collateral at the reporting date, adjusted for selling costs as appropriate.

When the discounted cash flow method is used to determine the ACL, management adjusts the effective interest rate used to discount expected cash flows to incorporate expected prepayments. The ACL on a TDR is measured using the same method as all other loans held for investment, except that the original interest rate is used to discount the expected cash flows, not the rate specified within the restructuring.

Determining the Contractual Term: Expected credit losses are estimated over the contractual term of the loans, adjusted for expected prepayments when appropriate. The contractual term excludes expected extensions, renewals, and modifications unless either of the following applies: management has a reasonable expectation at the reporting date that a TDR will be executed with an individual borrower or the extension or renewal options are included in the original or modified contract at the reporting date and are not unconditionally cancellable by United.

Premises and Equipment

Premises and equipment are stated at cost less accumulated depreciation. Depreciation is computed primarily using the straight line method over the estimated useful lives of the related assets. Costs incurred for maintenance and repairs are expensed as incurred. The range of estimated useful lives for buildings and improvements is 10 to 40 years, for land improvements, 10 years, and for furniture and equipment, 3 to 10 years. United periodically reviews the carrying value of premises and equipment for impairment whenever events or circumstances indicate that the carrying amount of such assets may not be fully recoverable.

Foreclosed Properties (Other Real Estate Owned)

Foreclosed Properties (Other Real Estate Owned)Foreclosed property is initially recorded at fair value, less cost to sell. If the fair value, less cost to sell at the time of foreclosure is less than the loan balance, the deficiency is recorded as a loan charge-off against the ACL. If the fair value, less cost to sell, of the foreclosed property decreases during the holding period, a valuation allowance is established with a charge to operating expenses. When the foreclosed property is sold, a gain or loss is recognized on the sale for the difference between the sales proceeds and the carrying amount of the property.

Goodwill and Other Intangible Assets

Goodwill is an asset representing the future economic benefits from other assets acquired that are not individually identified and separately recognized. Goodwill is measured as the excess of the consideration transferred, net of the fair value of identifiable assets acquired and liabilities assumed at the acquisition date. Goodwill is not amortized, but instead is tested for impairment annually or more frequently if events or circumstances exist that indicate a goodwill impairment test should be performed.

Other intangible assets, which are initially recorded at fair value, consist of core deposit and customer list intangibles resulting from acquisitions. Core deposit intangible assets are amortized over their estimated useful lives using the sum-of-the-years-digits method. Customer list intangibles are amortized over their estimated useful lives using the straight-line method.

Management evaluates other intangible assets for impairment whenever events or changes in circumstances indicate the carrying amount of the asset may not be recoverable.

Transfers of Financial Assets

Transfers of financial assets are accounted for as sales when control over the assets has been relinquished. Control over transferred assets is deemed to be surrendered when the assets have been isolated from United, the transferee obtains the right, free of conditions that constrain it from taking advantage of that right, to pledge or exchange the transferred assets and United does not maintain effective control over the transferred assets through an agreement to repurchase them before maturity.

Servicing Rights

United records a separate servicing asset for SBA loans, USDA loans, and residential mortgage loans when the loan is sold but servicing is retained. This asset represents the right to service the loans and receive a fee in compensation. Servicing assets are initially recorded at their fair value as a component of the sale proceeds. The fair value of the servicing assets is based on an analysis of discounted cash flows that incorporates estimates of (1) market servicing costs, (2) market-based prepayment rates, and (3) market profit margins. Servicing assets are included in other assets.

United has elected to subsequently measure the servicing assets for government guaranteed loans and residential mortgage loans at fair value. The rate of prepayment of loans serviced is the most significant estimate involved in the measurement process. Estimates of prepayment rates are based on market expectations of future prepayment rates, industry trends, and other considerations. Actual prepayment rates will differ from those projected by management due to changes in a variety of economic factors, including prevailing interest rates and the availability of alternative financing sources to borrowers. If actual prepayments of the loans being serviced were to occur more quickly than projected, the carrying value of servicing assets might have to be written down through a charge to earnings in the current period. If actual prepayments of the loans being serviced were to occur more slowly than had been projected, the carrying value of servicing assets could increase, and servicing income would exceed previously projected amounts.

United accounts for the servicing liabilities associated with sold equipment financing loans using the amortization method. Servicing liabilities are included in accrued expenses and other liabilities.

BOLI

United has purchased life insurance policies on certain key executives and members of management. United has also received life insurance policies on members of acquired bank management teams through acquisitions of other banks. BOLI is recorded at the amount that can be realized under the insurance contract at the balance sheet date, which is the cash surrender value adjusted for other changes or other amounts due that are probable at settlement.

Operating Leases

United records a ROU asset, included in other assets, and a related lease liability, included in other liabilities, for eligible operating leases for which it is the lessee, which include leases for land, buildings, and equipment. At lease commencement, United records the ROU asset and related lease liability based on the present value of lease payments over the lease term. Absent a readily determinable interest rate in the lease agreement, United utilizes the Bank’s incremental borrowing rate for secured borrowings as the discount rate used in the present value calculation. Payments related to these leases consist primarily of base rent and, in the case of building leases, additional operating costs associated with the leased property such as common area maintenance and utilities. In most cases these operating costs vary over the term of the lease, and therefore are classified as variable lease costs, which are recognized as incurred in the consolidated statement of income. In addition, certain operating leases include costs such as property taxes and insurance, which are recognized as incurred in the consolidated statement of

income. Many of United’s operating leases contain renewal options, which are included in the measurement of the ROU asset and lease liability to the extent they are reasonably certain to be exercised. United also subleases and leases certain real estate properties to third parties under operating leases. United does not recognize a lease liability or ROU asset on the consolidated balance sheet related to short-term leases with a term of less than one year. Lease payments for short-term leases are recognized as expense over the lease term.

Loan Commitments and Related Financial Instruments

Financial instruments include off-balance sheet credit instruments such as commitments to make loans and commercial letters of credit issued to meet customer financing needs. The face amount for these items represents the exposure to loss before considering customer collateral or ability to repay. Such financial instruments are recorded when they are funded.

Revenue from Contracts with Customers

In addition to lending and related activities, United offers various services to customers that generate revenue, certain of which are governed by ASC Topic 606 Revenue from Contracts with Customers. United’s services that fall within the scope of this topic are presented within noninterest income and include service charges and fees, wealth management fees, and other transaction-based fees. Revenue is recognized when the transactions occur or as services are performed over primarily monthly or quarterly periods. Payment is typically received in the period the transactions occur. Fees may be fixed or, where applicable, based on a percentage of transaction size.

Income Taxes

DTAs and DTLs are recorded for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Future tax benefits are recognized to the extent that realization of such benefits is more likely than not. DTAs and DTLs are measured using enacted tax rates expected to apply to taxable income in the years in which the assets and liabilities are expected to be recovered or settled. The effect of a change in tax rates on DTAs and DTLs is recognized in income tax expense during the period that includes the enactment date.

In the event the future tax consequences of differences between the financial reporting bases and the tax bases of assets and liabilities results in DTAs, an evaluation of the probability of being able to realize the future benefits indicated by such asset is required. A valuation allowance is provided for the portion of the DTA when it is more likely than not that some or all of the DTA will not be realized. In assessing the realizability of the DTAs, management considers the scheduled reversals of DTLs, projected future taxable earnings and prudent and feasible tax planning strategies. Management weighs both the positive and negative evidence, giving more weight to evidence that can be objectively verified.

The income tax benefit or expense is the total of the current year income tax due or refundable and the change in DTAs and DTLs.

A tax position is recognized as a benefit only if it is “more likely than not” that the tax position would be sustained in a tax examination, with a tax examination being presumed to occur. The amount recognized is the largest amount of tax benefit that is greater than 50 percent likely of being realized on examination. For tax positions not meeting the “more likely than not” test, no tax benefit is recorded.

United recognizes interest and / or penalties related to income tax matters in income tax expense.

Derivative Instruments and Hedging Activities

United’s interest rate risk management strategy incorporates the use of derivative instruments to minimize fluctuations in net income that are caused by interest rate volatility. The objective is to manage interest rate sensitivity by modifying the repricing or maturity characteristics of certain balance sheet assets and liabilities so that net interest revenue and certain interest sensitive components of noninterest revenue are not, on a material basis, adversely affected by movements in interest rates. United views this strategy as a prudent management of interest rate risk, such that net income is not exposed to undue risk presented by changes in interest rates. In carrying out this part of its interest rate risk management strategy, management uses derivatives, primarily interest rate swaps. Interest rate swaps generally involve the exchange of fixed- and variable-rate interest payments between two parties, based on a common notional principal amount and maturity date. United has also occasionally used interest rate caps to serve as an economic macro hedge of exposure to rising interest rates.

United originates certain residential mortgage loans with the intention of selling these loans. Between the time United enters into an interest-rate lock commitment to originate a residential mortgage loan that is to be held for sale and the time the loan is funded and eventually sold, the Company is subject to the risk of variability in market prices. United enters into forward sale agreements to mitigate risk and to protect the expected gain on the eventual loan sale. The commitments to originate residential mortgage loans and forward loan sales commitments are freestanding derivative instruments which are entered into as part of an economic hedging strategy to manage exposure related to mortgage loans held for sale.

To accommodate customers, United enters into interest rate swaps, caps or collars with certain commercial loan customers, with offsetting positions to dealers under a back-to-back swap/cap/collar program. In addition, United occasionally enters into credit risk participation agreements with counterparty banks to accept a portion of the credit risk related to interest rate swaps. This allows customers to execute an interest rate swap with one bank while allowing for the distribution of the credit risk among participating members. Credit risk participation agreements arise when United contracts with other financial institutions, as a guarantor, to share credit risk associated with certain interest rate swaps. These agreements provide for reimbursement of losses resulting from a third party default on the underlying swap. These transactions are typically executed in conjunction with a participation in a loan with the same customer. Collateral used to support the credit risk for the underlying lending relationship is also available to offset the risk of the credit risk participation.

United classifies its derivative financial instruments as either (1) a hedge of an exposure to changes in the fair value of a recorded asset or liability (“fair value hedge”), (2) a hedge of an exposure to changes in the cash flows of a recognized asset, liability or forecasted transaction (“cash flow hedge”), or (3) derivatives not designated as accounting hedges. Changes in the fair value of derivatives not designated as hedges are recognized in current period earnings. United has master netting agreements with the derivatives dealers with which it does business, but reflects gross assets and liabilities at fair value on the consolidated balance sheets.

United assesses hedge effectiveness at inception and over the life of the hedge. Management documents, at inception, its analysis of actual and expected hedge effectiveness. This analysis includes techniques such as regression analysis and hypothetical derivatives to demonstrate that the hedge is expected to be highly effective in offsetting corresponding changes in the fair value or cash flows of the hedged item. At least quarterly thereafter, the terms of the hedging instrument and the hedged item are assessed to determine whether a material change has occurred relating to the hedge relationship. If it is determined that a change has occurred, a quantitative analysis as described will occur to determine whether the hedge is expected to be highly effective in offsetting future corresponding changes in the fair value or cash flows of the hedged item. For a qualifying fair value hedge, the changes in the value of derivatives are recognized in current period earnings along with the corresponding changes in the fair value of the designated hedged item attributable to the risk being hedged. For a qualifying cash flow hedge, the changes in the fair value of the derivatives that have been highly effective are recognized in other comprehensive income until the related cash flows from the hedged item are recognized in earnings.

For fair value hedges and cash flow hedges, ineffectiveness is recognized in the same income statement line as interest accruals on the hedged item to the extent that changes in the value of the derivative instruments do not perfectly offset changes in the value of the hedged items. If the hedge ceases to be highly effective, United discontinues hedge accounting and recognizes the changes in fair value in current period earnings. If a derivative that qualifies as a fair value or cash flow hedge is terminated or the designation removed, the realized or then unrealized gain or loss is recognized into income over the life of the hedged item (fair value hedge) or over the time when the hedged item was forecasted to impact earnings (cash flow hedge). Immediate recognition in earnings is required upon sale or extinguishment of the hedged item (fair value hedge) or if it is probable that the hedged cash flows will not occur (cash flow hedge).

By using derivative instruments, United is exposed to credit and market risk. If the counterparty fails to perform, credit risk is represented by the fair value gain in a derivative. When the fair value of a derivative contract is positive, this situation generally indicates that the counterparty is obligated to pay United, and, therefore, creates a repayment risk for United. When the fair value of a derivative contract is negative, United is obligated to pay the counterparty and, therefore, has no repayment risk. United minimizes the credit risk in non-customer derivative instruments by entering into transactions with high-quality counterparties that are reviewed periodically by management. United also requires non-customer counterparties to pledge cash as collateral to cover the net exposure. All new non-customer derivatives that can be cleared are cleared through a central clearinghouse, which reduces counterparty exposure.

Derivative activities are monitored by the ALCO as part its oversight of asset/liability and treasury functions. The ALCO is responsible for implementing various hedging strategies that are developed through its analysis of data from financial simulation

models and other internal and industry sources. The resulting hedging strategies are then incorporated into the overall interest-rate risk management process.

Acquisition Activities

United accounts for business combinations under the acquisition method of accounting. Assets acquired and liabilities assumed are measured and recorded at fair value at the date of acquisition, including identifiable intangible assets. If the fair value of net assets purchased exceeds the fair value of consideration paid, a bargain purchase gain is recognized at the date of acquisition. Conversely, if the consideration paid exceeds the fair value of the net assets acquired, goodwill is recognized at the acquisition date. Fair values are subject to refinement for a period not to exceed one year after the closing date of an acquisition as information relative to closing date fair values becomes available.

Fair values for acquired loans are generally based on a discounted cash flow methodology that considers credit loss expectations, market interest rates and other market factors such as liquidity from the perspective of a market participant. Loans are grouped together according to similar characteristics and are generally treated in the aggregate when applying various valuation techniques. The probability of default, loss given default and prepayment assumptions are the key factors driving credit losses which are embedded into the estimated cash flows. These assumptions are informed by internal data on loan characteristics, historical loss experience, and current and forecasted economic conditions. The interest and liquidity component of the estimate is determined by discounting interest and principal cash flows through the expected life of each loan. The discount rates used for loans are based on current market rates for new originations of comparable loans and include adjustments for liquidity. The discount rate does not include a factor for credit losses as that has been included as a reduction to the estimated cash flows. For additional information about the accounting for purchased loans see PCD Loans (CECL) under the Loans and Leases section of this footnote.

All identifiable intangible assets that are acquired in a business combination are recognized at fair value on the acquisition date. Identifiable intangible assets are recognized separately if they arise from contractual or other legal rights or if they are separable (i.e., capable of being sold, transferred, licensed, rented, or exchanged separately from the entity). Deposit liabilities and the related depositor relationship intangible assets may be exchanged in observable exchange transactions. As a result, the depositor relationship intangible asset is considered identifiable, because the separability criterion has been met.

Earnings Per Common Share

Earnings Per Common ShareBasic earnings per common share is net income available to common shareholders divided by the weighted average number of shares of common stock outstanding during the period. All outstanding unvested share-based payment awards that contain rights to nonforfeitable dividends are considered participating securities for this calculation. Additionally, shares issuable to participants in United’s deferred compensation plan are considered to be participating securities for purposes of calculating basic earnings per share. Accordingly, net income available to common shareholders is calculated pursuant to the two-class method, whereby net income after subtracting preferred stock dividends is allocated between common shareholders and participating securities. Diluted earnings per common share includes the dilutive effect of additional potential shares of common stock issuable under stock options, unvested restricted stock units without nonforfeitable rights to dividends, warrants and securities convertible into common stock.

Loss Contingencies

Loss ContingenciesLoss contingencies, including claims and legal actions arising in the ordinary course of business, are recorded as liabilities when the likelihood of loss is probable and an amount or range of loss can be reasonably estimated. Management does not believe there are such matters that will have a material effect on the financial statements.

Dividend Restrictions

Dividend RestrictionsBanking regulations require maintaining certain capital levels and may limit dividends paid by the Bank to the Holding Company or by the Holding Company to shareholders. As a South Carolina state-chartered bank, the Bank is permitted to pay a dividend of up to 100% of its current year earnings without requesting approval of the SCBFI, provided certain conditions are met. Prior to July 1, 2021, as a Georgia state-chartered bank, the Board could declare dividends from the Bank to the Holding Company out of retained earnings of up to fifty percent of the Bank’s net income from the previous year without notifying or seeking approval from the GADBF, provided certain conditions were met.

Fair Value of Financial Instruments

Fair Value of Financial InstrumentsFair values of financial instruments are estimated using relevant market information and other assumptions as more fully disclosed in Note 14. Fair value estimates involve uncertainties and matters of significant judgment regarding interest rates, credit risk, prepayments, and other factors, especially in the absence of broad markets for particular items. Changes in assumptions or in market conditions could significantly affect these estimates.

Fair value measurements are determined based on the assumptions that market participants would use in pricing the asset or liability. As a basis for considering market participant assumptions in fair value measurements, United uses a fair value hierarchy that distinguishes between market participant assumptions based on market data obtained from sources independent of the reporting entity (observable inputs that are classified within Levels 1 and 2 of the hierarchy) and the reporting entity’s own assumptions about market participant assumptions (unobservable inputs classified within Level 3 of the hierarchy). United has processes in place to review the significant valuation inputs and to reassess how the instruments are classified in the valuation framework.

Fair Value Hierarchy

Level 1 Valuation is based upon quoted prices (unadjusted) in active markets for identical assets or liabilities that United has the ability to access.

Level 2 Valuation is based upon quoted prices for similar assets and liabilities in active markets, as well as inputs that are observable for the asset or liability (other than quoted prices), such as interest rates, foreign exchange rates, and yield curves that are observable at commonly quoted intervals.

Level 3 Valuation is generated from model-based techniques that use at least one significant assumption based on unobservable inputs for the asset or liability, which are typically based on an entity’s own assumptions, as there is little, if any, related market activity.

In instances where the determination of the fair value measurement is based on inputs from different levels of the fair value hierarchy, the level in the fair value hierarchy within which the entire fair value measurement falls is based on the lowest level input that is significant to the fair value measurement in its entirety. United’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment, and considers factors specific to the asset or liability.

The following is a description of the valuation methodologies used for assets and liabilities recorded at fair value.

Investment Securities

AFS debt securities and equity securities with readily determinable fair values are recorded at fair value on a recurring basis. Fair value measurement is based upon quoted prices, if available. If quoted prices are not available, fair values are measured using independent pricing models or other model-based valuation techniques such as the present value of future cash flows, adjusted for the security’s credit rating, prepayment assumptions and other factors such as credit loss assumptions. Level 1 securities include those traded on an active exchange, such as the New York Stock Exchange, U.S. Treasury securities that are traded by dealers or brokers in active over-the-counter markets and money market funds. Level 2 securities include mortgage-backed securities issued by government sponsored entities, municipal bonds, corporate debt securities and asset-backed securities and are valued based on observable inputs that include: quoted market prices for similar assets, quoted market prices that are not in an active market or other inputs that are observable in the market and can be corroborated by observable market data for substantially the full term of the securities. Securities classified as Level 3 include those traded in less liquid markets and are valued based on estimates obtained from broker-dealers that are not directly observable.

Deferred Compensation Plan Assets and Liabilities

Included in other assets in the consolidated balance sheets are assets related to employee deferred compensation plans. The assets associated with these plans are invested in mutual funds and classified as Level 1. Deferred compensation liabilities, also classified as Level 1, are carried at the fair value of the obligation to the employee, which mirrors the fair value of the invested assets and is included in other liabilities in the consolidated balance sheets.

Mortgage Loans Held for Sale

United has elected the fair value option for newly originated mortgage loans held for sale in order to reduce certain timing differences and better match changes in fair values of the loans with changes in the value of derivative instruments used to economically hedge them. The fair value of mortgage loans held for sale is determined using quoted prices for a similar asset, adjusted for specific attributes of that loan and are classified as Level 2.

Derivative Financial Instruments

United uses derivatives to manage interest rate risk. The valuation of these instruments is typically determined using widely accepted valuation techniques including discounted cash flow analysis on the expected cash flows of each derivative. This analysis reflects the contractual terms of the derivatives, including the period to maturity, and uses observable market-based inputs, including interest rate curves and implied volatilities. The fair values of interest rate swaps are determined using the market standard methodology of netting the discounted future fixed cash receipts and the discounted expected variable cash payments. The variable cash payments are based on an expectation of future interest rates (forward curves) derived from observable market interest rate curves. United also uses best effort and mandatory delivery forward loan sale commitments to hedge risk in its mortgage lending business.

United incorporates credit valuation adjustments (“CVAs”) as necessary to appropriately reflect the respective counterparty’s nonperformance risk in the fair value measurements. In adjusting the fair value of its derivative contracts for the effect of nonperformance risk, United has considered the effect of netting and any applicable credit enhancements, such as collateral postings, thresholds and guarantees.

Management has determined that the majority of the inputs used to value its derivatives fall within Level 2 of the fair value hierarchy. However, the CVAs associated with these derivatives utilize Level 3 inputs, such as estimates of current credit spreads, to evaluate the likelihood of default by itself and its counterparties. Generally, management’s assessment of the significance of the CVAs has indicated that they are not a significant input to the overall valuation of the derivatives. In cases where management’s assessment indicates that the CVA is a significant input, the related derivative is disclosed as a Level 3 value.

Other derivatives classified as Level 3 include structured derivatives for which broker quotes, used as a key valuation input, were not observable. Risk participation agreements are classified as Level 3 instruments due to the incorporation of significant Level 3 inputs used to evaluate the probability of funding and the likelihood of customer default. Interest rate lock commitments, which relate to mortgage loan commitments, are categorized as Level 3 instruments as the fair value of these instruments is based on unobservable inputs for commitments that United does not expect to fund.

Servicing Rights for Residential Mortgage and SBA/USDA Loans

United recognizes servicing rights upon the sale of residential mortgage and SBA/USDA loans sold with servicing retained. Management has elected to carry these assets at fair value. Given the nature of the assets, the key valuation inputs are unobservable and management considers these Level 3 assets. For disclosure regarding the fair value of servicing rights, see Note 10.

Stock-Based Compensation

Stock-Based CompensationUnited uses the fair value method of recognizing expense for stock-based compensation based on the fair value of option and restricted stock unit awards at the date of grant. United accounts for forfeitures as they occur.
