Accounting Policies [Abstract]
Accounting Policies	Accounting Policies The accounting and financial reporting policies of United Community Banks, Inc. and its subsidiaries (collectively referred to herein as “United”) conform to accounting principles generally accepted in the United States (“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. In addition to those items mentioned below, a more detailed description of United’s accounting policies is included in its Annual Report on Form 10-K for the year ended December 31, 2019 (the “2019 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 2019 10-K. Certain amounts reported in prior periods' consolidated financial statements have been reclassified to conform to the current presentation. Debt Securities Debt securities are classified as held-to-maturity and carried at amortized cost when management has the positive intent and ability to hold them to maturity. Debt securities are classified as available-for-sale when they might be sold before maturity. Securities available-for-sale 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 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 available-for-sale to held-to-maturity are included in the balance of accumulated other comprehensive income in the consolidated balance sheets. These unrealized holding gains or losses are amortized 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 non-accrual is reversed against interest income. Allowance for Credit Losses (“ACL”) - Held-to-Maturity Securities: Management measures expected credit losses on held-to-maturity debt securities on a collective basis by major security type. Accrued interest receivable on held-to-maturity debt securities totaled $1.00 million at June 30, 2020 and was excluded from the estimate of credit losses. The estimate of expected credit losses considers historical credit loss information that is adjusted for current conditions and reasonable and supportable forecasts. Management classifies the held-to-maturity portfolio into the following major security types: State and political subdivisions, residential mortgage-backed, agency and commercial mortgage-backed, agency. All of the residential and commercial mortgage-backed securities held by United are issued by U.S. government agencies. 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. As a result, no ACL was recorded on the held-to-maturity portfolio at June 30, 2020. ACL - Available-For-Sale Securities: For available-for-sale 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 debt securities available-for-sale 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. 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 available-for-sale security is confirmed or when either of the criteria regarding intent or requirement to sell is met. At June 30, 2020, there was no ACL related to the available-for-sale portfolio. Accrued interest receivable on available-for-sale debt securities totaled $7.72 million at June 30, 2020 and was excluded from the estimate of credit losses. 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. Accrued interest receivable related to loans totaled $28.0 million at June 30, 2020 and was reported in accrued interest receivable on the consolidated balance sheets. 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 using methods that approximate a level yield without anticipating prepayments. The accrual of interest is discontinued when a loan becomes 90 days past due and is not well collateralized and in the process of collection, or when management believes, after considering economic and business conditions and collection efforts, that the principal or interest will not be collectible in the normal course of business. Past due status is based on contractual terms of the loan. All interest accrued but not received for loans placed on nonaccrual is reversed against interest income. Interest received on such loans is accounted for on the cost-recovery method, until qualifying for return to accrual. Under the cost-recovery method, 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. 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 estimated or contractual residual values less unearned income and security deposits. The determination of residual 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. Purchased Credit Deteriorated (“PCD”) Loans: Upon adoption of Accounting Standards Codification (“ASC”) Topic 326, Financial Instruments - Credit Losses (“ASC 326”), loans that were designated as purchased credit impaired (“PCI”) loans under the previous accounting guidance were classified as PCD loans without reassessment. In future acquisitions, United may purchase 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 the amount paid. An initial ACL is determined using the same methodology as other loans held for investment, but with no impact to earnings. The initial ACL determined on a collective basis is allocated to individual loans. 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. ACL - Loans 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. Expected recoveries do not exceed the aggregate of amounts previously charged-off and expected to be charged-off. 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. The ACL 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. Home equity lines of credit - Risks common to home equity lines of credit are general economic conditions, including an increase in unemployment rates, and declining real estate values which 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. 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 troubled debt restructuring will be executed with an individual borrower or the extension or renewal options are included in the original or modified contract at the reporting date and are not unconditionally cancellable by United. Troubled Debt Restructurings (“TDR”s): 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. 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. As discussed in Note 2, in accordance with the Coronavirus Aid, Relief, and Economic Security Act (“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. 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.

Accounting Changes and Error Corrections [Abstract]
Accounting Standards Updates and Recently Adopted Standards	Accounting Standards Updates and Recently Adopted Standards On January 1, 2020, United adopted ASC 326, which replaced the incurred loss impairment framework in prior GAAP with a current expected credit loss (“CECL”) framework, which requires an estimate of credit losses for the remaining estimated life of the financial asset using historical experience, current conditions, and reasonable and supportable forecasts and generally applies to financial assets measured at amortized cost, including loan receivables and held-to-maturity debt securities, and some off-balance sheet credit exposures such as unfunded commitments to extend credit. Financial assets measured at amortized cost will be presented at the net amount expected to be collected by using an ACL. PCD loans will receive an initial allowance at the acquisition date that represents an adjustment to the amortized cost basis of the loan, with no impact to earnings. Credit losses relating to available-for-sale debt securities will be recorded through an ACL prospectively, with such allowance limited to the amount by which fair value is below amortized cost. United adopted ASC 326 as of January 1, 2020 using the modified retrospective method for loans, leases and off-balance sheet credit exposures. Adoption of this guidance resulted in an $8.75 million increase in the ACL, comprised of increases in the ACL for loans of $6.88 million and the ACL for unfunded commitments of $1.87 million, with $3.59 million of the increase reclassified from the amortized cost basis of PCD financial assets that were previously classified as PCI. The cumulative effect adjustment to retained earnings was $3.53 million, net of tax. Calculated credit losses on held-to-maturity debt securities were not material and there was no impact to the available-for-sale securities portfolio or other financial instruments. Results for reporting periods beginning after January 1, 2020 are presented under ASC 326 while prior period amounts continue to be reported in accordance with previously applicable GAAP (“Incurred Loss”). The ACL for the majority of loans and leases was 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. In connection with the adoption, management has implemented changes to relevant systems, processes and controls where necessary. Model validation was completed during the fourth quarter of 2019 and implementation of the accounting, reporting and governance processes to comply with the new guidance was completed in the first quarter of 2020. United’s CECL allowance will fluctuate over time due to macroeconomic conditions and forecasts as well as the size and composition of the loan portfolios. United has adopted the relief provided by federal banking regulatory agencies for the delay of the adverse capital impact of CECL at adoption and during the subsequent two-year period following adoption. This optional two-year delay is followed by an optional three-year transition period to phase out the aggregate amount of capital benefit provided during the initial two-year delay. Under the transition provision, the amount of aggregate capital benefit is phased out by 25% each year with the full impact of adoption completely recognized by the beginning of the sixth year. United adopted ASC 326 using the prospective transition approach for PCD assets that were previously classified as PCI. In accordance with the standard, management did not reassess whether PCI assets met the criteria of PCD assets as of the date of adoption. As mentioned above, the amortized cost basis of the PCD assets was adjusted to reflect the addition of $3.59 million of the ACL. The remaining noncredit discount (based on the adjusted amortized cost basis) will be accreted into interest income at a rate that approximates the effective interest rate as of January 1, 2020. With regard to PCD assets, because United elected to disaggregate the former PCI pools and no longer considers these pools to be the unit of account, contractually delinquent PCD loans will be reported as nonaccrual loans using the same criteria as other loans. Similarly, although management did not reassess whether modifications to individual acquired financial assets accounted for in pools were TDRs as of the date of adoption, PCD loans that are restructured and meet the definition of troubled debt restructurings after the adoption of CECL will be reported as such. United elected not to measure an allowance for credit losses for accrued interest receivable and instead to reverse interest income on those loans that are 90 days past due, to exclude accrued interest receivable from the amortized cost basis of financial instruments subject to CECL and to separately state the balance of accrued interest receivable on the consolidated balance sheet. In addition, United elected to adjust the discount rate used to calculate credit losses for expected prepayments and will include all changes in discounted cash flows as credit loss. As a practical expedient, United has also elected to use the fair value of collateral when determining the ACL for loans if repayment is expected to be provided substantially through the operation or sale of the collateral when the borrower is experiencing financial difficulty (collateral-dependent loans). On March 27, 2020, the CARES Act was signed into law. The CARES Act included a number of provisions that were applicable to United, including the following: •Accounting Relief for TDRs: The CARES Act provided that modifications under certain forbearance conditions for loans that were not more than 30 days past due at December 31, 2019 will not be considered TDRs for regulatory reporting and GAAP. •Optional Delay and Regulatory Relief for CECL Implementation: The CARES Act stipulated that large SEC filers have the option of delaying the adoption of CECL from January 1, 2020 to the earlier of the end of the COVID-19 emergency period or December 31, 2020. Banks that were required to implement CECL by the end of 2020 were granted the option to defer any impact of CECL on regulatory capital for two years before beginning the original three-year regulatory phase-in period, for a total five-year phase-in period. Although United did not elect to delay the adoption of CECL, the Company did elect the five-year phase-in period for regulatory capital purposes, as discussed above. •Paycheck Protection Program (“PPP”): The CARES Act created the PPP through the Small Business Administration (“SBA”), which allowed United to lend money to small businesses to maintain employee payrolls through the crisis with guarantees from the SBA. Under this program, loan amounts may be forgiven if the borrower maintains employee payrolls or restores payrolls afterwards. In March 2020, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2020-03, Codification Improvements to Financial Instruments. This update clarified certain minor issues within the codification, including, among other things, debt securities disclosure for financial institutions and determination of the contractual term of a net investment in a lease. The standard was effective immediately, and did not have a material impact on the consolidated financial statements. In March 2020, the FASB issued ASU No. 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting. This update provides expedients for contracts that are modified because of reference rate reform, including receivables, debt, leases, and certain derivatives. In addition, the update provides a one-time election to sell or transfer debt securities classified as held-to-maturity that reference a rate that is affected by reference rate reform. The update is effective as of March 12, 2020 through December 31, 2022. Adoption of this update did not have a material impact on the consolidated financial statements. In April 2019, the FASB issued ASU No. 2019-04, Codification Improvements to Topic 326, Financial Instruments - Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825 Financial Instruments. In addition to amending guidance related to the new CECL standard, this update clarifies certain aspects of hedge accounting and recognition and measurement of financial instruments. United adopted this update as of January 1, 2020, with no material impact on the consolidated financial statements. In January 2017, the FASB issued ASU No. 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. This update eliminates Step 2 from the goodwill impairment test, which required an entity to calculate the implied fair value of goodwill by valuing a reporting unit’s assets and liabilities using the same process that would be required to value assets and liabilities in a business combination. Instead, the amendments require that an entity perform its annual goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. United adopted this update as of January 1, 2020, with no material impact on the consolidated financial statements.

At June 30, 2020, there were 21 debt securities available-for-sale and 4 debt securities held-to-maturity that were in an unrealized loss position. 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 June 30, 2020 were primarily attributable to changes in interest rates.

No impairment charges were recognized during the three and six months ended June 30, 2019. At adoption of CECL on January 1, 2020 and at June 30, 2020, calculated credit losses on held-to-maturity debt securities were not material due to the high credit quality of the portfolio, which included securities issued or guaranteed by U.S. Government agencies and high credit quality municipal securities. As a result, no ACL was recorded on the held-to-maturity portfolio at June 30, 2020. In addition, at June 30, 2020, there was no ACL related to the available-for-sale portfolio. See Note 1 for additional details on the adoption of CECL as it relates to the securities portfolio.

Realized gains and losses are derived using the specific identification method for determining the cost of securities sold. The following table summarizes available-for-sale securities sales activity for the three and six months ended June 30, 2020 and 2019 (in thousands).

Risk Ratings

United categorizes commercial loans, with the exception of equipment financing receivables, into risk categories based on relevant information about the ability of borrowers to service their debt such as: current financial information, historical payment experience, credit documentation, public information, and current industry and economic trends, among other factors. 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.

Watch. 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 the pass / fail grading system, loans that are on nonaccrual status, become past due 90 days, or are in bankruptcy are classified as “fail” and all other loans are classified as “pass”. For purposes of the table below, loans in these categories that are classified as “fail” are reported as substandard and all other loans are reported as pass.

Based on the most recent analysis performed, the amortized cost of loans by risk category by vintage year as of the date indicated is as follows (in thousands).

As of June 30, 2020, United used a one-year reasonable and supportable forecast period. The changes in loss rates used as the basis for the estimate of credit losses during this period were modeled using historical data from peer banks and macroeconomic forecast data obtained from a third party vendor, which were then applied to United’s recent default experience as a starting point. At June 30, 2020, the forecast indicated that the markets in which United operates will experience a decline in economic conditions and an increase in the unemployment rate over the next year, primarily as a result of the COVID-19 pandemic. The increase in the ACL compared to January 1, 2020 and March 31, 2020 was primarily attributable to the worsening trends in the forecast at June 30, 2020 compared to the earlier forecasts used, with the primary economic forecast driver being the change in the unemployment rate. United adjusted the economic forecast by eliminating the initial spike in unemployment to account for the impact of government stimulus programs, which mitigated some of the negative impact on forecasted losses. In addition, United further adjusted the economic forecast for residential mortgage loans and income producing commercial real estate to moderate losses in those portfolios.

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, United reverted to through-the-cycle average default rates using peer data from 2000 to 2017. For loans secured by residential mortgages, the peer data was adjusted for changes in lending practices designed to prevent the magnitude of losses observed during the mortgage crisis.

PPP loans were considered low risk assets due to the related 100% guarantee by the SBA.

Goodwill	6 Months Ended
Goodwill	Jun. 30, 2020
Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill	Goodwill Goodwill represents the premium paid for acquired companies above the net fair value of the assets acquired and liabilities assumed, including separately identifiable intangible assets. At June 30, 2020 and December 31, 2019, the net carrying value of goodwill was $327 million. Goodwill is not amortized but is assessed for impairment on an annual basis, or more often if events or circumstances indicate there may be impairment, referred to as a triggering event. Upon the occurrence of a triggering event, accounting guidance allows for an assessment of qualitative factors to determine whether it is more likely than not, or a greater than 50% likelihood, that the fair value of the entity is less than its carrying amount, including goodwill. When it is more likely than not that impairment has occurred, management is required to perform a quantitative analysis and, if necessary, adjust the carrying amount of goodwill by recording a goodwill impairment loss. During the latter part of the first quarter and the second quarter of 2020, as a result of market concerns about the potential impact of COVID-19, United’s stock price declined such that it traded below book value for much of that time period. As a result of this triggering event, management has qualitatively assessed and concluded that there is not a greater than 50% likelihood that United’s fair value is less than its carrying amount as of June 30, 2020, given the anticipated short duration of the change in macroeconomic conditions and excess of value as of the latest annual test performed as of September 30, 2019. Management will continue to monitor and assess the impact of the pandemic on the Company’s value.

Derivatives and Hedging Activities

Risk Management Objective of Using Derivatives

United is exposed to certain risks arising from both its business operations and economic conditions. United principally manages its exposures to a wide variety of business and operational risks through management of its core business activities. United manages interest rate risk through a combination of pricing and term structure of deposit product offerings, the amount and duration of its investment securities portfolio and wholesale funding and, to a lesser degree, through the use of derivative financial instruments. From time to time, United enters into derivative financial instruments to manage interest rate risk exposures that arise from business activities that result in the receipt or payment of future known and uncertain cash amounts, the value of which are determined by interest rates. Derivative financial instruments are used to manage differences in the amount, timing, and duration of known or expected cash receipts and known or expected cash payments principally related to loans, investment securities, wholesale borrowings and deposits.

United has master netting agreements with the derivatives dealers with which it does business, but has elected to reflect gross assets and liabilities on the consolidated balance sheets.

United clears certain derivatives centrally through the Chicago Mercantile Exchange (“CME”). 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.

The table below presents the fair value of derivative financial instruments as of the dates indicated as well as their classification on the consolidated balance sheets (in thousands):

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. During the second quarter of 2020, United entered into three cash flow hedges using interest rate caps and swaps with an aggregate notional amount of $120 million 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 other comprehensive income. 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 $576,000 of losses from accumulated other comprehensive income into earnings related to these agreements.

At December 31, 2019 United had no active cash flow hedges. The loss remaining in other comprehensive income from prior hedges that had previously been de-designated was being amortized into earnings over the original term of the swaps as the forecasted transactions that the swaps were originally designated to hedge were still expected to occur. During the second quarter of 2019, United amortized the remaining balance of losses on terminated hedging positions from other comprehensive income, which was the only effect of cash flow hedges on the consolidated statements of income for the three and six months ended June 30, 2019. See Note 11 for further detail.

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 June 30, 2020 and December 31, 2019, United had three and four, respectively, interest rate swaps with an aggregate notional amount of $27.9 million and $37.9 million, respectively, that were designated as fair value hedges of fixed-rate brokered time deposits. The swaps involved the receipt of fixed-rate amounts from a counterparty in exchange for United making variable rate payments over the life of the agreements.

In certain cases, the estate of deceased brokered certificate of deposit holders may put the certificate of deposit back to United at par upon the death of the holder. When these estate puts occur, a gain or loss is recognized for the difference between the fair value and the par amount of the deposits put back. The change in the fair value of brokered time deposits that are being hedged in fair value hedging relationships reported in the table above includes gains and losses from estate puts.

The table below presents the effect of derivatives in hedging relationships on the consolidated statement of income for the periods indicated (in thousands).

Derivatives Not Designated as Hedging Instruments

Customer derivative positions include swaps, caps, and corridors 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 London Interbank Offered Rate (“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. United accounts for most newly originated mortgage loans at fair value pursuant to the fair value option, and these loans are not reflected in the table above. 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).

Credit-Risk-Related Contingent Features

United manages its credit exposure on derivatives transactions by entering into a bilateral credit support agreement with each non-customer counterparty. 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.

United’s agreements with each of its derivative counterparties provide that if either party defaults on any of its indebtedness, then it could also be declared in default on its derivative obligations. The agreements with derivatives counterparties also include provisions that if not met, could result in United being declared in default. United has agreements with certain of its derivative counterparties that provide that if United fails to maintain its status as a well-capitalized institution or is subject to a prompt corrective action directive, the counterparty could terminate the derivative positions and United would be required to settle its obligations under the agreements. Derivatives that are centrally cleared do not have credit-risk-related features that would require additional collateral if United’s credit rating were downgraded.

Assets and Liabilities Measured at Fair Value

6 Months Ended

Jun. 30, 2020

Fair Value Disclosures [Abstract]

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

Debt securities available-for-sale 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 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 (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. During the second quarter of 2020, certain derivative assets were transferred from Level 2 to Level 3 of the fair value hierarchy due to a change in the assessment of significance of the CVA.

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.

Fair Value Option

United records mortgage loans held for sale at fair value under the fair value option. Interest income on these loans is calculated based on the note rate of the loan and is recorded in interest revenue. The following tables present the fair value and outstanding principal balance of these loans, as well as the gain or loss recognized resulting from the change in fair value for the periods indicated (in thousands).


	Mortgage Loans Held for Sale
	June 30, 2020		December 31, 2019
Outstanding principal balance	$	94,335	$	56,613
Fair value	99,477		58,484

	2020		2019		2020		2019
Mortgage loan gains and other related fees	$	1,546	$	569	$	3,271	$	875

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 all assets that were still held as of June 30, 2020 and December 31, 2019, 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
June 30, 2020
Loans	$	—	$	—	$	12,654	$	12,654

December 31, 2019
Loans	$	—	$	—	$	20,977	$	20,977

Loans 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 80% of appraised value which considers 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).

Common and Preferred Stock	6 Months Ended
Common and Preferred Stock	Jun. 30, 2020
Equity [Abstract]
Common and Preferred Stock	Common and Preferred Stock In November of 2019, United’s Board of Directors authorized an expansion of the existing common stock repurchase plan to authorize the repurchase of its common stock up to $50 million. The program is scheduled to expire on the earlier of United’s repurchase of its common stock having an aggregate purchase price of $50 million or December 31, 2020. Under the program, shares may be repurchased in the open market or in privately negotiated transactions, from time to time, subject to market conditions. During the six months ended June 30, 2020 and 2019, 826,482 and 305,052 shares, respectively, were repurchased under the program. No shares were purchased during the three months ended June 30, 2020 and 2019. As of June 30, 2020, United had remaining authorization to repurchase up to $29.2 million of outstanding common stock under the program. During the second quarter of 2020, United issued $100 million, or 4,000 shares, of Series I perpetual non-cumulative preferred stock (“Preferred Stock”) with a dividend rate of 6.875% per annum for net proceeds of $96.7 million and corresponding depositary shares each representing a 1/1,000th interest in one share of Preferred Stock. If declared, dividends will be payable quarterly in arrears beginning on September 15, 2020. The Preferred Stock has no stated maturity and redemption is solely at the option of United in whole, but not in part, upon the occurrence of a regulatory capital treatment event, as defined. In addition, the Preferred Stock may be redeemed on or after September 15, 2025 at a cash redemption price equal to $25,000 per share (equivalent to $25 per depositary share) plus any declared and unpaid dividends. As of June 30, 2020, the Preferred Stock had a carrying amount of $96.7 million.

Stock-Based Compensation

6 Months Ended

Jun. 30, 2020

Share-based Payment Arrangement [Abstract]

Stock-Based Compensation

United has an equity compensation plan that allows for grants of various share-based compensation. Options granted under the plan have an exercise price no less than the fair market value of the underlying stock at the date of grant. 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 June 30, 2020, 1.28 million additional awards could be granted under the plan.

The following table shows stock option activity for the first six months of June 30, 2020.


Options	Shares	Weighted- Average Exercise Price		Weighted- Average Remaining Contractual Term (Years)	Aggregate Intrinsic Value ($000)
Outstanding at December 31, 2019	1,500	$	27.95


Expired	(1,500)	27.95
Outstanding at June 30, 2020	—	—		0.00	$	—

Exercisable at June 30, 2020	—	—		0.00	—

The fair value of each option is estimated on the date of grant using the Black-Scholes model. No stock options were granted during the six months ended June 30, 2020 and 2019. United recognized no compensation expense related to stock options during the six months ended June 30, 2020 and 2019.

The table below presents restricted stock unit activity for the first six months of June 30, 2020.


Restricted Stock Unit Awards	Shares	Weighted- Average Grant- Date Fair Value		Weighted- Average Remaining Contractual Term (Years)	Aggregate Intrinsic Value ($000)
Outstanding at December 31, 2019	808,424	$	27.94
Granted	62,055	23.20
Vested	(113,748)	27.83			$	2,798
Cancelled	(18,754)	26.45
Outstanding at June 30, 2020	737,977	27.47		3.6	14,848

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 market 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 six months ended June 30, 2020 and 2019, expense of $4.04 million and $5.83 million, respectively, was recognized related to restricted stock unit and performance stock unit awards granted to United employees. Of the expense related to restricted stock unit awards during the six months ended June 30, 2019, $1.38 million related to the modification of existing awards resulting from an acceleration of vesting of awards due to retirement and $740,000 related to awards granted in conjunction with an acquisition, both of which were recognized in merger-related and other charges in the consolidated statement of income. The remaining expense of $3.71 million for the six months ended June 30, 2019 was recognized in salaries and employee benefits expense, as was the entire amount for the six months ended June 30, 2020. In addition, for the six months ended June 30, 2020 and 2019, $217,000 and $169,000, respectively, was recognized in other operating expense for restricted stock unit awards granted to members of United’s Board of Directors.

A deferred income tax benefit related to stock-based compensation expense of $1.09 million and $1.53 million was included in the determination of income tax expense for the six months ended June 30, 2020 and 2019, respectively. As of June 30, 2020, there was $11.4 million of unrecognized expense related to non-vested restricted stock unit and performance stock unit awards granted under the plan. That cost is expected to be recognized over a weighted-average period of 2.2 years. As of June 30, 2020, there was no unrecognized expense related to non-vested stock options granted under the plan.

Regulatory Capital Requirements Under Banking Regulations [Abstract]

Regulatory Matters

As of June 30, 2020, United and the Bank were categorized as well-capitalized under the regulatory framework for prompt corrective action in effect at such time. To be categorized as well-capitalized at June 30, 2020, United and the Bank must have exceeded the well-capitalized guideline ratios in effect at such 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 June 30, 2020, and there have been no conditions or events since year-end that would change the status of well-capitalized.

Pursuant to the CARES Act, United has adopted relief provided by federal banking regulatory agencies for the delay of the adverse capital impact of CECL at adoption and during the subsequent two-year period after adoption. This optional two-year delay is followed by an optional three-year transition period to phase out the aggregate amount of capital benefit provided during the initial two-year delay. Under the transition provision, the amount of aggregate capital benefit is phased out by 25% each year with the full impact of adoption completely recognized by the beginning of the sixth year.

Regulatory capital ratios at June 30, 2020 and December 31, 2019, along with the minimum amounts required for capital adequacy purposes and to be well-capitalized under prompt corrective action provisions in effect at such times are presented below for United and the Bank (dollars in thousands):

Commitments and Contingencies Disclosure [Abstract]

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).


	June 30, 2020		December 31, 2019
Financial instruments whose contract amounts represent credit risk:
Commitments to extend credit	$	2,291,128	$	2,126,275
Letters of credit	26,554		22,533

United holds minor investments in certain limited partnerships for Community Reinvestment Act purposes. As of June 30, 2020, United had committed to fund an additional $10.1 million related to future capital calls that are not 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.

Business Combinations [Abstract]

Acquisitions

Acquisition of Three Shores Bancorporation, Inc.

Subsequent to quarter-end, on July 1, 2020, United completed its previously announced acquisition of Three Shores Bancorporation, Inc. (“Three Shores”), including its wholly-owned subsidiary, Seaside National Bank & Trust (“Seaside”), headquartered in Orlando, Florida. Seaside operated a 14 branch network located in key Florida metropolitan markets. As of June 30, 2020, Three Shores had total assets of $2.16 billion, loans of $1.47 billion and deposits of $1.79 billion. Seaside has merged into the Bank, but will operate under the brand name Seaside Bank and Trust.

Under the terms of the merger agreement, Three Shores shareholders received $188 million in total consideration, of which $164 million was United common stock and $24.1 million was cash. United issued 8.13 million shares to Three Shores shareholders in the acquisition. The acquisition will be accounted for as a business combination. Due to the timing of the acquisition, United is currently in the process of completing the purchase accounting and has not made all of the remaining required disclosures, such as the fair value of assets acquired and supplemental pro forma information, which will be disclosed in subsequent filings.

Acquisition of First Madison Bank and Trust

On May 1, 2019, United completed the acquisition of First Madison Bank & Trust (“FMBT”). Information related to the fair value of assets acquired and liabilities assumed is included in United’s 2019 10-K. The following table discloses the impact of the acquisition of FMBT since the acquisition date through June 30, 2019, and certain pro forma information as if FMBT had been acquired on January 1, 2018. These results combine the historical results of FMBT with United’s consolidated statement of income and, while adjustments were made for the estimated impact of certain fair value adjustments and other acquisition-related activity, they are not necessarily indicative of what would have occurred had the acquisitions taken place in earlier years.

Merger-related costs from the FMBT acquisition of $924,000 and $1.02 million, respectively, have been excluded from the three and six months 2019 pro forma information presented below. The actual results and pro forma information were as follows (in thousands):

Accounting Policies (Policies)	6 Months Ended
Accounting Policies (Policies)	Jun. 30, 2020
Accounting Policies [Abstract]
Basis of Presentation and Consolidation	The accounting and financial reporting policies of United Community Banks, Inc. and its subsidiaries (collectively referred to herein as “United”) conform to accounting principles generally accepted in the United States (“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. In addition to those items mentioned below, a more detailed description of United’s accounting policies is included in its Annual Report on Form 10-K for the year ended December 31, 2019 (the “2019 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 2019 10-K. Certain amounts reported in prior periods' consolidated financial statements have been reclassified to conform to the current presentation.
Debt Securities	Debt Securities Debt securities are classified as held-to-maturity and carried at amortized cost when management has the positive intent and ability to hold them to maturity. Debt securities are classified as available-for-sale when they might be sold before maturity. Securities available-for-sale 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 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 available-for-sale to held-to-maturity are included in the balance of accumulated other comprehensive income in the consolidated balance sheets. These unrealized holding gains or losses are amortized 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 non-accrual is reversed against interest income.
Allowance for Credit Losses - Held-to-Maturity and Available-for-Sale Securities and Off-Balance Sheet Credit Exposures	Allowance for Credit Losses (“ACL”) - Held-to-Maturity Securities: Management measures expected credit losses on held-to-maturity debt securities on a collective basis by major security type. Accrued interest receivable on held-to-maturity debt securities totaled $1.00 million at June 30, 2020 and was excluded from the estimate of credit losses. The estimate of expected credit losses considers historical credit loss information that is adjusted for current conditions and reasonable and supportable forecasts. Management classifies the held-to-maturity portfolio into the following major security types: State and political subdivisions, residential mortgage-backed, agency and commercial mortgage-backed, agency. All of the residential and commercial mortgage-backed securities held by United are issued by U.S. government agencies. 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. As a result, no ACL was recorded on the held-to-maturity portfolio at June 30, 2020. ACL - Available-For-Sale Securities: For available-for-sale 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 debt securities available-for-sale 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. 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 available-for-sale security is confirmed or when either of the criteria regarding intent or requirement to sell is met. At June 30, 2020, there was no ACL related to the available-for-sale portfolio. Accrued interest receivable on available-for-sale debt securities totaled $7.72 million at June 30, 2020 and was excluded from the estimate of credit losses. 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 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. Accrued interest receivable related to loans totaled $28.0 million at June 30, 2020 and was reported in accrued interest receivable on the consolidated balance sheets. 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 using methods that approximate a level yield without anticipating prepayments. The accrual of interest is discontinued when a loan becomes 90 days past due and is not well collateralized and in the process of collection, or when management believes, after considering economic and business conditions and collection efforts, that the principal or interest will not be collectible in the normal course of business. Past due status is based on contractual terms of the loan. All interest accrued but not received for loans placed on nonaccrual is reversed against interest income. Interest received on such loans is accounted for on the cost-recovery method, until qualifying for return to accrual. Under the cost-recovery method, 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. 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 estimated or contractual residual values less unearned income and security deposits. The determination of residual 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. Purchased Credit Deteriorated (“PCD”) Loans: Upon adoption of Accounting Standards Codification (“ASC”) Topic 326, Financial Instruments - Credit Losses (“ASC 326”), loans that were designated as purchased credit impaired (“PCI”) loans under the previous accounting guidance were classified as PCD loans without reassessment. In future acquisitions, United may purchase 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 the amount paid. An initial ACL is determined using the same methodology as other loans held for investment, but with no impact to earnings. The initial ACL determined on a collective basis is allocated to individual loans. 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.
ACL Loans	ACL - Loans 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. Expected recoveries do not exceed the aggregate of amounts previously charged-off and expected to be charged-off. 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. The ACL 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. Home equity lines of credit - Risks common to home equity lines of credit are general economic conditions, including an increase in unemployment rates, and declining real estate values which 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. 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 troubled debt restructuring will be executed with an individual borrower or the extension or renewal options are included in the original or modified contract at the reporting date and are not unconditionally cancellable by United. Troubled Debt Restructurings (“TDR”s): 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. 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. As discussed in Note 2, in accordance with the Coronavirus Aid, Relief, and Economic Security Act (“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.
Accounting Standards Updates and Recently Adopted Standards	Accounting Standards Updates and Recently Adopted Standards On January 1, 2020, United adopted ASC 326, which replaced the incurred loss impairment framework in prior GAAP with a current expected credit loss (“CECL”) framework, which requires an estimate of credit losses for the remaining estimated life of the financial asset using historical experience, current conditions, and reasonable and supportable forecasts and generally applies to financial assets measured at amortized cost, including loan receivables and held-to-maturity debt securities, and some off-balance sheet credit exposures such as unfunded commitments to extend credit. Financial assets measured at amortized cost will be presented at the net amount expected to be collected by using an ACL. PCD loans will receive an initial allowance at the acquisition date that represents an adjustment to the amortized cost basis of the loan, with no impact to earnings. Credit losses relating to available-for-sale debt securities will be recorded through an ACL prospectively, with such allowance limited to the amount by which fair value is below amortized cost. United adopted ASC 326 as of January 1, 2020 using the modified retrospective method for loans, leases and off-balance sheet credit exposures. Adoption of this guidance resulted in an $8.75 million increase in the ACL, comprised of increases in the ACL for loans of $6.88 million and the ACL for unfunded commitments of $1.87 million, with $3.59 million of the increase reclassified from the amortized cost basis of PCD financial assets that were previously classified as PCI. The cumulative effect adjustment to retained earnings was $3.53 million, net of tax. Calculated credit losses on held-to-maturity debt securities were not material and there was no impact to the available-for-sale securities portfolio or other financial instruments. Results for reporting periods beginning after January 1, 2020 are presented under ASC 326 while prior period amounts continue to be reported in accordance with previously applicable GAAP (“Incurred Loss”). The ACL for the majority of loans and leases was 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. In connection with the adoption, management has implemented changes to relevant systems, processes and controls where necessary. Model validation was completed during the fourth quarter of 2019 and implementation of the accounting, reporting and governance processes to comply with the new guidance was completed in the first quarter of 2020. United’s CECL allowance will fluctuate over time due to macroeconomic conditions and forecasts as well as the size and composition of the loan portfolios. United has adopted the relief provided by federal banking regulatory agencies for the delay of the adverse capital impact of CECL at adoption and during the subsequent two-year period following adoption. This optional two-year delay is followed by an optional three-year transition period to phase out the aggregate amount of capital benefit provided during the initial two-year delay. Under the transition provision, the amount of aggregate capital benefit is phased out by 25% each year with the full impact of adoption completely recognized by the beginning of the sixth year. United adopted ASC 326 using the prospective transition approach for PCD assets that were previously classified as PCI. In accordance with the standard, management did not reassess whether PCI assets met the criteria of PCD assets as of the date of adoption. As mentioned above, the amortized cost basis of the PCD assets was adjusted to reflect the addition of $3.59 million of the ACL. The remaining noncredit discount (based on the adjusted amortized cost basis) will be accreted into interest income at a rate that approximates the effective interest rate as of January 1, 2020. With regard to PCD assets, because United elected to disaggregate the former PCI pools and no longer considers these pools to be the unit of account, contractually delinquent PCD loans will be reported as nonaccrual loans using the same criteria as other loans. Similarly, although management did not reassess whether modifications to individual acquired financial assets accounted for in pools were TDRs as of the date of adoption, PCD loans that are restructured and meet the definition of troubled debt restructurings after the adoption of CECL will be reported as such. United elected not to measure an allowance for credit losses for accrued interest receivable and instead to reverse interest income on those loans that are 90 days past due, to exclude accrued interest receivable from the amortized cost basis of financial instruments subject to CECL and to separately state the balance of accrued interest receivable on the consolidated balance sheet. In addition, United elected to adjust the discount rate used to calculate credit losses for expected prepayments and will include all changes in discounted cash flows as credit loss. As a practical expedient, United has also elected to use the fair value of collateral when determining the ACL for loans if repayment is expected to be provided substantially through the operation or sale of the collateral when the borrower is experiencing financial difficulty (collateral-dependent loans). On March 27, 2020, the CARES Act was signed into law. The CARES Act included a number of provisions that were applicable to United, including the following: •Accounting Relief for TDRs: The CARES Act provided that modifications under certain forbearance conditions for loans that were not more than 30 days past due at December 31, 2019 will not be considered TDRs for regulatory reporting and GAAP. •Optional Delay and Regulatory Relief for CECL Implementation: The CARES Act stipulated that large SEC filers have the option of delaying the adoption of CECL from January 1, 2020 to the earlier of the end of the COVID-19 emergency period or December 31, 2020. Banks that were required to implement CECL by the end of 2020 were granted the option to defer any impact of CECL on regulatory capital for two years before beginning the original three-year regulatory phase-in period, for a total five-year phase-in period. Although United did not elect to delay the adoption of CECL, the Company did elect the five-year phase-in period for regulatory capital purposes, as discussed above. •Paycheck Protection Program (“PPP”): The CARES Act created the PPP through the Small Business Administration (“SBA”), which allowed United to lend money to small businesses to maintain employee payrolls through the crisis with guarantees from the SBA. Under this program, loan amounts may be forgiven if the borrower maintains employee payrolls or restores payrolls afterwards. In March 2020, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2020-03, Codification Improvements to Financial Instruments. This update clarified certain minor issues within the codification, including, among other things, debt securities disclosure for financial institutions and determination of the contractual term of a net investment in a lease. The standard was effective immediately, and did not have a material impact on the consolidated financial statements. In March 2020, the FASB issued ASU No. 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting. This update provides expedients for contracts that are modified because of reference rate reform, including receivables, debt, leases, and certain derivatives. In addition, the update provides a one-time election to sell or transfer debt securities classified as held-to-maturity that reference a rate that is affected by reference rate reform. The update is effective as of March 12, 2020 through December 31, 2022. Adoption of this update did not have a material impact on the consolidated financial statements. In April 2019, the FASB issued ASU No. 2019-04, Codification Improvements to Topic 326, Financial Instruments - Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825 Financial Instruments. In addition to amending guidance related to the new CECL standard, this update clarifies certain aspects of hedge accounting and recognition and measurement of financial instruments. United adopted this update as of January 1, 2020, with no material impact on the consolidated financial statements. In January 2017, the FASB issued ASU No. 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. This update eliminates Step 2 from the goodwill impairment test, which required an entity to calculate the implied fair value of goodwill by valuing a reporting unit’s assets and liabilities using the same process that would be required to value assets and liabilities in a business combination. Instead, the amendments require that an entity perform its annual goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. United adopted this update as of January 1, 2020, with no material impact on the consolidated financial statements.

- Definition

Total of all stockholders' equity (deficit) items, net of receivables from officers, directors, owners, and affiliates of the entity which are attributable to the parent. The amount of the economic entity's stockholders' equity attributable to the parent excludes the amount of stockholders' equity which is allocable to that ownership interest in subsidiary equity which is not attributable to the parent (noncontrolling interest, minority interest). This excludes temporary equity and is sometimes called permanent equity.
