The accompanying interim consolidated financial statements have not been audited. All material intercompany balances and transactions have been eliminated. A more detailed description of United’s accounting policies is included in its 2021 10-K. In management’s opinion, all accounting adjustments necessary to accurately reflect the financial position and results of operations on the accompanying financial statements have been made. These adjustments are normal and recurring accruals considered necessary for a fair and accurate presentation. The results for interim periods are not necessarily indicative of results for the full year or any other interim periods.

Accounting Changes and Error Corrections [Abstract]
Accounting Standards Updates and Recently Adopted Standards	Accounting Standards Updates and Recently Adopted Standards Recently Adopted Standards 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. United adopted this update as of January 1, 2022, with no material impact on the consolidated financial statements. Recently Issued Standards In March 2022, the FASB issued ASU No. 2022-01, Derivatives and Hedging (Topic 815): Fair Value Hedging - Portfolio Layer Method . The update expands the current last-of-layer method to a portfolio layer method which allows multiple hedged layers of a single closed portfolio and non-prepayable financial assets. In addition, the update specifies that eligible hedging instruments may include spot-starting or forward-starting swaps and that the number of hedged layers corresponds with the number of hedges designated. Finally, the update provides additional guidance on the accounting for and disclosure of hedge basis adjustments. For public entities, this guidance is effective for fiscal years beginning after December 15, 2022. United does not expect the new guidance to have a material impact on the consolidated financial statements. In March 2022, the FASB issued ASU No. 2022-02, Financial Instruments - Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures . The update eliminates the previous accounting guidance for TDRs by creditors, while enhancing disclosure requirements for certain loan refinancings and restructurings when a borrower is experiencing financial difficulty. The update also requires that an entity disclose current-period gross charge-offs by year of origination. For public entities, this guidance is effective for fiscal years beginning after December 15, 2022. United does not expect the new guidance to have a material impact on the consolidated financial statements. In June 2022, the FASB issued ASU No. 2022-03, Fair Value Measurement (Topic 820) - Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions

Acquisitions	Acquisitions Acquisition of Reliant On January 1, 2022, United acquired all of the outstanding common stock of Reliant in a stock transaction. Reliant operated a 25-branch network primarily located in Middle Tennessee. United’s operating results for the three and nine months ended September 30, 2022 include the operating results of the acquired business for the period subsequent to the acquisition date of January 1, 2022. The purchased assets and assumed liabilities were recorded at their acquisition date fair values and are summarized in the table below (in thousands) . Reliant Fair Value Recorded by United (1) January 1, 2022 Assets Cash and cash equivalents $ 62,867 Debt securities 249,107 Loans held for sale 116,406 Loans held for investment 2,320,737 Premises and equipment 35,631 Bank-owned life insurance 78,170 Accrued interest receivable 12,027 Net deferred tax asset 5,793 Core deposit intangible 14,500 Other assets 59,768 Total assets acquired $ 2,955,006 Liabilities Deposits $ 2,504,823 Short-term borrowings 27,000 Long-term debt 76,730 Other liabilities 48,620 Total liabilities assumed 2,657,173 Total identifiable net assets 297,833 Consideration transferred Cash 624 Common stock issued (16,571,545 shares) 595,581 Options converted 795 Total fair value of consideration transferred 597,000 Goodwill $ 299,167 (1) Fair values are preliminary and 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. Goodwill represents the intangible value of Reliant’s business and reputation within the markets it served and is not expected to be deductible for income tax purposes. The Reliant core deposit intangible will be amortized over its expected useful life of 10 years using the sum-of-the-years-digits method.

Investments, Debt and Equity Securities [Abstract]
Investment Securities	Investment Securities During the first nine months of 2022, United transferred AFS debt securities to HTM with a fair value on the transfer date of $1.29 billion, which included unrealized losses recorded in AOCI totaling $87.4 million. No securities were transferred from AFS to HTM during the third quarter of 2022. Transfer date unrealized losses are amortized and reclassified out of AOCI as a yield adjustment, which is offset by discount accretion of the transferred HTM securities. Amortization of transfer date unrealized losses and discount accretion are recognized over the remaining life of the securities. The amortized cost basis, unrealized gains and losses and fair value of HTM debt securities as of the dates indicated are as follows (in thousands) .

United does not intend to sell nor does it believe it will be required to sell securities in an unrealized loss position prior to the recovery of their amortized cost basis. Unrealized losses at September 30, 2022 were primarily attributable to changes in interest rates. At September 30, 2022 and December 31, 2021, estimated credit losses and, thus, the related ACL on HTM debt securities were de minimis due to the high credit quality of the portfolio, which included securities issued or guaranteed by U.S. Government agencies, GSEs, high credit quality municipalities and supranational entities. As a result, no ACL was recorded on the HTM portfolio at September 30, 2022 or December 31, 2021. In addition, based on the assessments performed at September 30, 2022 and December 31, 2021, there was no ACL required related to the AFS portfolio.

United analyzes loans individually by classifying the loans as to credit risk. This analysis is performed on a continual basis. United uses the following definitions for its risk ratings: Pass. Loans in this category are considered to have a low probability of default and do not meet the criteria of the risk categories below. Special Mention. Loans in this category are presently protected from apparent loss; however, weaknesses exist that could cause future impairment, including the deterioration of financial ratios, past due status and questionable management capabilities. These loans require more than the ordinary amount of supervision. Collateral values generally afford adequate coverage, but may not be immediately marketable. Substandard. These loans are inadequately protected by the current net worth and paying capacity of the obligor or by the collateral pledged. Specific and well-defined weaknesses exist that may include poor liquidity and deterioration of financial ratios. The loan may be past due and related deposit accounts experiencing overdrafts. There is the distinct possibility that United will sustain some loss if deficiencies are not corrected. If possible, immediate corrective action is taken. Doubtful. Specific weaknesses characterized as Substandard that are severe enough to make collection in full highly questionable and improbable. There is no reliable secondary source of full repayment. Loss. Loans categorized as Loss have the same characteristics as Doubtful; however, probability of loss is certain. Loans classified as Loss are charged off. Equipment Financing Receivables and Consumer Purpose Loans. United applies a pass / fail grading system to all equipment financing receivables and consumer purpose loans. Under this system, loans that are on nonaccrual status, become past due 90 days, or are in bankruptcy and 30 or more days past due are classified as “fail” and all other loans are classified as “pass”. For reporting purposes, loans in these categories that are classified as “fail” are reported as substandard and all other loans are reported as pass.

The ACL related to unfunded commitments is included in other liabilities in the consolidated balance sheet. At both September 30, 2022 and December 31, 2021, United used a one-year reasonable and supportable forecast period. Expected credit losses were estimated using a regression model for each segment based on historical data from peer banks combined with a third party vendor’s baseline economic forecast to predict the change in credit losses. These estimates were then combined with a starting value that was based on United’s recent default experience, with the results subject to a floor. At September 30, 2022, United applied qualitative adjustments to the model output for the income producing commercial real estate, commercial construction, HELOCs, residential mortgage and residential construction portfolios. With regard to income producing commercial real estate, the qualitative adjustments reflected continued credit concerns related to the senior care portfolio, elevated criticized loans relative to the pre-pandemic period and inflationary concerns related to the impact of rising rates on commercial real estate values. Qualitative adjustments for the other categories lowered the amount of required allowance due to management’s expectation with respect to the timing of deteriorating economic conditions in the forecast. For periods beyond the reasonable and supportable forecast period of one year, United reverted to historical credit loss information on a straight line basis over two years. For all collateral types excluding residential mortgage and manufactured housing, United reverted to through-the-cycle average default rates using peer data from 2000 to 2017. For loans secured by residential mortgages and manufactured housing, the peer data was adjusted to account for the changes in lending practices designed to prevent the magnitude of losses observed during the mortgage crisis.

CME rules legally characterize variation margin payments for centrally cleared derivatives as settlements of the derivatives’ exposure rather than as collateral. As a result, the variation margin payment and the related derivative instruments are considered a single unit of account for accounting purposes. Variation margin, as determined by the CME, is settled daily. As a result, derivative contracts that clear through the CME have an estimated fair value of zero. Hedging Derivatives Cash Flow Hedges of Interest Rate Risk United enters into cash flow hedges to mitigate exposure to the variability of future cash flows or other forecasted transactions. As of September 30, 2022 and December 31, 2021, United utilized interest rate caps and swaps to hedge the variability of cash flows due to changes in interest rates on certain of its variable-rate subordinated debt and trust preferred securities. United considers these derivatives to be highly effective at achieving offsetting changes in cash flows attributable to changes in interest rates. Therefore, changes in the fair value of these derivative instruments are recognized in OCI. Gains and losses related to changes in fair value are reclassified into earnings in the periods the hedged forecasted transactions occur. Losses representing amortization of the premium recorded on cash flow hedges, which is a component excluded from the assessment of effectiveness, are recognized in earnings on a straight-line basis in the same caption as the hedged item over the term of the hedge. Over the next twelve months, United expects to reclassify $2.34 million of gains from AOCI into earnings related to these agreements. Fair Value Hedges of Interest Rate Risk United is exposed to changes in the fair value of certain of its fixed-rate obligations due to changes in interest rates. United uses interest rate derivatives to manage its exposure to changes in fair value on these instruments attributable to changes in interest rates. For derivatives designated and that qualify as fair value hedges, the gain or loss on the derivative as well as the offsetting loss or gain on the hedged item attributable to the hedged risk are recognized in earnings. United includes the gain or loss on the hedged items in the same income statement line item as the offsetting loss or gain on the related derivatives. At December 31, 2021, United had an interest rate swap that was designated as a fair value hedge of fixed-rate brokered time deposits. During the first quarter of 2022, the hedged brokered deposit and the associated swap matured. The swap involved the receipt of fixed-rate amounts from a counterparty in exchange for United making variable rate payments over the life of the agreements. The table below presents the effect of derivatives in hedging relationships, all of which are interest rate contracts, on the consolidated statement of income for the periods indicated (in thousands) . Three Months Ended September 30, Nine Months Ended September 30, 2022 2021 2022 2021 Total interest expense presented in the consolidated statements of income $ (14,113) $ (6,636) $ (29,855) $ (23,547) Effect of hedging relationships on interest expense: Net income recognized on fair value hedges — 43 28 167 Net expense recognized on cash flow hedges (1) (48) (153) (295) (444) (1) Includes premium amortization expense excluded from the assessment of hedge effectiveness of $119,000 for both the three months ended September 30, 2022 and 2021, and $353,000 for both the nine months ended September 30, 2022 and 2021. Derivatives Not Designated as Hedging Instruments Customer derivative positions include swaps, caps, and collars between United and certain commercial loan customers with offsetting positions to dealers under a back-to-back program. In addition, United occasionally enters into credit risk participation agreements with counterparty banks to accept or transfer a portion of the credit risk related to interest rate swaps. The agreements, which are typically executed in conjunction with a participation in a loan with the same customer, allow customers to execute an interest rate swap with one bank while allowing for the distribution of the credit risk among participating members. United also has three interest rate swap contracts that are not designated as hedging instruments but are economic hedges of market-linked brokered certificates of deposit. The market-linked brokered certificates of deposit contain embedded derivatives that are bifurcated from the host instruments and are marked to market through earnings. The fair value marks on the market-linked swaps and the bifurcated embedded derivatives tend to move in opposite directions with changes in 90-day LIBOR and therefore provide an economic hedge. In addition, 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, United 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. Fair value adjustments on these derivative instruments are recorded within mortgage loan gains and other related fee income in the consolidated statements of income. The table below presents the gains and losses recognized in income on derivatives not designated as hedging instruments for the periods indicated (in thousands) .

The credit support agreements require collateralization of exposures beyond specified minimum threshold amounts. The details of these agreements, including the minimum thresholds, vary by counterparty.

Assets and Liabilities Measured

Assets and Liabilities Measured at Fair Value	9 Months Ended
	Sep. 30, 2022
Fair Value Disclosures [Abstract]
Assets and Liabilities Measured at Fair Value	Assets and Liabilities Measured at Fair Value 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 when 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. The 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 MBS issued by GSEs, municipal bonds, corporate debt securities, asset-backed securities and supranational entity 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 or models which incorporate unobservable inputs. Deferred Compensation Plan Assets and Liabilities Included in other assets in the consolidated balance sheet 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 sheet. Mortgage Loans Held for Sale United has elected the fair value option for most of its 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. In connection with the Reliant acquisition, United acquired certain mortgage loans held for sale for which the fair value option was not elected; these loans are carried at the lower of aggregate cost or fair value. 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 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 and SBA/USDA Loans United recognizes servicing rights upon the sale of residential and SBA/USDA loans sold with servicing retained. Management has elected to carry these assets at fair value. Given the nature of these assets, the key valuation inputs are unobservable and management classifies these assets as Level 3.

Interest income on these loans is calculated based on the note rate of the loan and is recorded in interest revenue. In connection with the Reliant acquisition, United acquired mortgage loans held for sale accounted for under the lower of cost or fair value method. These loans are separately disclosed under the heading “Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis” within this footnote. The following tables present the fair value and outstanding principal balance of loans accounted for under the fair value option, as well as the gain or loss recognized from the change in fair value for the periods indicated (in thousands) . Mortgage Loans Held for Sale September 30, 2022 December 31, 2021 Outstanding principal balance $ 20,180 $ 42,581 Fair value 19,888 44,109 Gain (Loss) from Change in Fair Value on Mortgage Loans Held for Sale Location Three Months Ended Nine Months Ended 2022 2021 2022 2021 Mortgage loan gains and other related fees $ (809) $ (1,609) $ (1,820) $ (3,330) Changes in fair value were mostly offset by hedging activities. An immaterial portion of these amounts was attributable to changes in instrument-specific credit risk. Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis United may be required, from time to time, to measure certain assets at fair value on a nonrecurring basis. These adjustments to fair value usually result from the application of the lower of the amortized cost or fair value accounting or write-downs of individual assets due to impairment. The following table presents the fair value hierarchy and carrying value of assets that were still held as of September 30, 2022 and December 31, 2021, for which a nonrecurring fair value adjustment was recorded during the year-to-date periods presented (in thousands) . Level 1 Level 2 Level 3 Total September 30, 2022 Loans held for investment $ — $ — $ 1,820 $ 1,820 Mortgage loans held for sale — — 2,079 2,079 December 31, 2021 Loans held for investment $ — $ — $ 2,536 $ 2,536 Mortgage loans held for sale that were acquired from Reliant were subject to a nonrecurring fair value adjustment resulting from the application of the lower of the amortized cost or fair value accounting. As of September 30, 2022, these loans were classified as nonrecurring Level 3 because the valuation of these loans was based on indicative bids provided by a broker, not corroborated by market transactions. Loans held for investment that are reported above as being measured at fair value on a nonrecurring basis are generally impaired loans that have either been partially charged off or have specific reserves assigned to them. Nonaccrual loans that are collateral dependent are generally written down to net realizable value, which reflects fair value less the estimated costs to sell. Specific reserves that are established based on appraised value of collateral are considered nonrecurring fair value adjustments as well. When the fair value of the collateral is based on an observable market price or a current appraised value, United records the impaired loan as nonrecurring Level 2. When an appraised value is not available or management determines the fair value of the collateral is further impaired below the appraised value and there is no observable market price, United records the impaired loan as nonrecurring Level 3. Assets and Liabilities Not Measured at Fair Value For financial instruments that have quoted market prices, those quotes are used to determine fair value. Financial instruments that have no defined maturity, have a remaining maturity of 180 days or less, or reprice frequently to a market rate, are assumed to have a fair value that approximates reported book value, after taking into consideration any applicable credit risk. If no market quotes are available, financial instruments are valued by discounting the expected cash flows using an estimated current market interest rate for the financial instrument. For off-balance sheet derivative instruments, fair value is estimated as the amount that United would receive or pay to terminate the contracts at the reporting date, taking into account the current unrealized gains or losses on open contracts. Cash and cash equivalents and repurchase agreements have short maturities and therefore the carrying value approximates fair value. Due to the short-term settlement of accrued interest receivable and payable, the carrying amount closely approximates fair value. Fair value estimates are made at a specific point in time, based on relevant market information and information about the financial instrument. These estimates do not reflect the premium or discount on any particular financial instrument that could result from the sale of United’s entire holdings. All estimates are inherently subjective in nature. Changes in assumptions could significantly affect the estimates. Fair value estimates are based on existing on and off-balance sheet financial instruments without attempting to estimate the value of anticipated future business and the value of assets and liabilities that are not considered financial instruments. Significant assets and liabilities that are not considered financial instruments include the mortgage banking operation, brokerage network, deferred income taxes, premises and equipment and goodwill. In addition, the tax ramifications related to the realization of the unrealized gains and losses can have a significant effect on fair value estimates and have not been considered in the estimates. Off-balance sheet instruments (commitments to extend credit and standby letters of credit) for which draws can be reasonably predicted are generally short-term in maturity and are priced at variable rates. Therefore, the estimated fair value associated with these instruments is immaterial. The carrying amount and fair values as of the dates indicated for other financial instruments that are not measured at fair value on a recurring basis are as follows (in thousands) . Fair Value Level Carrying Amount Level 1 Level 2 Level 3 Total September 30, 2022 Assets: HTM debt securities $ 2,676,405 $ 17,253 $ 2,223,907 $ — $ 2,241,160 Loans and leases, net 14,733,982 — — 14,250,071 14,250,071 Liabilities: Deposits 20,321,142 — 20,315,750 — 20,315,750 Long-term debt 324,515 — — 313,944 313,944 December 31, 2021 Assets: HTM debt securities $ 1,156,098 $ — $ 1,148,804 $ — $ 1,148,804 Loans and leases, net 11,657,814 — — 11,607,821 11,607,821 Liabilities: Deposits 18,241,179 — 18,239,934 — 18,239,934 Long-term debt 247,360 — — 267,064 267,064

Stock-Based Compensation

Stock-Based Compensation	9 Months Ended

Share-Based Payment Arrangement [Abstract]
Stock-Based Compensation	Stock-Based Compensation United has an equity compensation plan that allows for grants of various share-based compensation. The general terms of the plan include a vesting period (usually four years) with an exercisable period not to exceed ten years. Certain options and restricted stock unit awards provide for accelerated vesting if there is a change in control (as defined in the plan document). As of September 30, 2022, 2.80 million additional awards could be granted under the plan. The table below presents restricted stock unit and option activity for the nine months ended September 30, 2022. Restricted Stock Unit Awards Options Shares Weighted- Aggregate Shares Weighted- Weighted- Aggregate Outstanding at December 31, 2021 808,474 $ 25.15 35,460 $ 8.38 Granted 335,866 32.81 48,239 20.88 Released / Exercised (289,860) 25.11 $ 10,252 (16,257) 20.77 $ 252 Cancelled (29,925) 26.06 — — Outstanding at September 30, 2022 824,555 28.25 27,293 67,442 14.33 3.0 1,266 Vested / Exercisable at September 30, 2022 — — 67,442 14.33 3.0 1,266 Options granted in 2022 reflect options assumed in the Reliant acquisition, with the weighted average exercise price of Reliant’s fully vested converted options determined pursuant to the purchase agreement. The value of the Reliant options was determined using a Black-Scholes model and was included in the purchase price for the acquisition. No compensation expense relating to options was included in earnings for the nine months ended September 30, 2022 and 2021. Compensation expense for restricted stock units and performance stock units without market conditions is based on the market value of United’s common stock on the date of grant. Compensation expense for performance stock units with market conditions is based on the grant date per share fair value, which was estimated using the Monte Carlo Simulation valuation model. United recognizes the impact of forfeitures as they occur. The value of restricted stock unit and performance stock unit awards is amortized into expense over the service period. For the nine months ended September 30, 2022 and 2021, expense of $6.24 million and $4.42 million, respectively, was recognized related to restricted stock unit and performance stock unit awards granted to United employees, which was included in salaries and employee benefits expense. In addition, for the nine months ended September 30, 2022 and 2021, $412,000 and $397,000, respectively, was recognized in other expense for restricted stock unit awards granted to members of United’s Board of Directors.

Regulatory Capital Requirements Under Banking Regulations [Abstract]
Regulatory Matters	Regulatory Matters As of September 30, 2022, United and the Bank were categorized as well-capitalized under the regulatory requirements in effect at that time. To be categorized as well-capitalized, United and the Bank must have exceeded the well-capitalized guideline ratios in effect at the time, as set forth in the table below, and have met certain other requirements. Management believes that United and the Bank exceeded all well-capitalized requirements at September 30, 2022, and there have been no conditions or events since quarter-end that would change the status of well-capitalized. Regulatory capital ratios at September 30, 2022 and December 31, 2021, along with the minimum amounts required for capital adequacy purposes and to be well-capitalized under regulatory requirements in effect at such times, are presented below for United and the Bank (dollars in thousands) : United Community Banks, Inc.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies United is party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit and letters of credit. These instruments involve, to varying degrees, elements of credit risk in excess of the amount recognized in the balance sheet. The contract amounts of these instruments reflect the extent of involvement United has in particular classes of financial instruments. The exposure to credit loss in the event of nonperformance by the other party to the financial instrument for commitments to extend credit and letters of credit written is represented by the contractual amount of these instruments. United uses the same credit policies in making commitments and conditional obligations as it uses for underwriting on-balance sheet instruments. In most cases, collateral or other security is required to support financial instruments with credit risk. The following table summarizes the contractual amount of off-balance sheet instruments as of the dates indicated (in thousands) . September 30, 2022 December 31, 2021 Financial instruments whose contract amounts represent credit risk: Commitments to extend credit $ 4,592,092 $ 3,591,975 Letters of credit 53,526 29,312 United holds minor investments in certain entities for tax credit and Community Reinvestment Act purposes. As of September 30, 2022 and December 31, 2021, the Bank had a recorded investment of $79.8 million and $52.7 million, respectively, in such investments, which is included in other assets on the consolidated balance sheet. As of September 30, 2022, United had committed to fund an additional $6.96 million related to future capital calls that are not reflected in the consolidated balance sheet. As of September 30, 2022, the Holding Company also had $18.1 million in commitments for future capital calls to fintech fund limited partnerships that have not been reflected in the consolidated balance sheet. United, in the normal course of business, is subject to various pending and threatened lawsuits in which claims for monetary damages are asserted. Although it is not possible to predict the outcome of these lawsuits, or the range of any possible loss, management, after consultation with legal counsel, does not anticipate that the ultimate aggregate liability, if any, arising from these lawsuits will have a material adverse effect on United’s financial position or results of operations.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	United’s accounting and financial reporting policies conform to GAAP and reporting guidelines of banking regulatory authorities. The accompanying interim consolidated financial statements have not been audited. All material intercompany balances and transactions have been eliminated. A more detailed description of United’s accounting policies is included in its 2021 10-K. In management’s opinion, all accounting adjustments necessary to accurately reflect the financial position and results of operations on the accompanying financial statements have been made. These adjustments are normal and recurring accruals considered necessary for a fair and accurate presentation. The results for interim periods are not necessarily indicative of results for the full year or any other interim periods. The accompanying unaudited consolidated financial statements should be read in conjunction with the consolidated financial statements and related notes appearing in United’s 2021 10-K.
Recently Adopted Standards and Recently Issued Standards	Recently Adopted Standards 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. United adopted this update as of January 1, 2022, with no material impact on the consolidated financial statements. Recently Issued Standards In March 2022, the FASB issued ASU No. 2022-01, Derivatives and Hedging (Topic 815): Fair Value Hedging - Portfolio Layer Method . The update expands the current last-of-layer method to a portfolio layer method which allows multiple hedged layers of a single closed portfolio and non-prepayable financial assets. In addition, the update specifies that eligible hedging instruments may include spot-starting or forward-starting swaps and that the number of hedged layers corresponds with the number of hedges designated. Finally, the update provides additional guidance on the accounting for and disclosure of hedge basis adjustments. For public entities, this guidance is effective for fiscal years beginning after December 15, 2022. United does not expect the new guidance to have a material impact on the consolidated financial statements. In March 2022, the FASB issued ASU No. 2022-02, Financial Instruments - Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures . The update eliminates the previous accounting guidance for TDRs by creditors, while enhancing disclosure requirements for certain loan refinancings and restructurings when a borrower is experiencing financial difficulty. The update also requires that an entity disclose current-period gross charge-offs by year of origination. For public entities, this guidance is effective for fiscal years beginning after December 15, 2022. United does not expect the new guidance to have a material impact on the consolidated financial statements. In June 2022, the FASB issued ASU No. 2022-03, Fair Value Measurement (Topic 820) - Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions
