Accounting Policies

Accounting Policies [Abstract]
Accounting Policies	Note 1 – Accounting Policies The accounting and financial reporting policies of United Community Banks, Inc. (“United”) and its subsidiaries conform to accounting principles generally accepted in the United States (“GAAP”) and reporting guidelines of banking regulatory authorities and regulators. The accompanying interim consolidated financial statements have not been audited. All material intercompany balances and transactions have been eliminated. A more detailed description of United’s accounting policies is included in its Annual Report on Form 10-K for the year ended December 31, 2016. Effective January 1, 2017, management elected to begin measuring residential mortgage servicing rights at fair value. The cumulative effect adjustment of this election to retained earnings, net of income tax effect, was $437,000. 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 statement. The results for interim periods are not necessarily indicative of results for the full year or any other interim periods. Certain 2016 amounts have been reclassified to conform to the 2017 presentation. As discussed in the Form 10-K for the year ended December 31, 2016, certain loan balances previously shown as retail loans were reclassified to several commercial categories to better align the reporting with the business purpose or underlying credit risk of the loans, rather than the collateral type. The reclassifications moved residential mortgages and home equity lines from the residential mortgage and home equity lines of credit categories to the owner-occupied and income-producing commercial real estate categories. Although these loans were secured by one-to-four family residential properties, their purpose was commercial since they included residential home rental property and business purpose loans secured by the borrower’s primary residence. In addition, residential construction loans were reclassified to the commercial construction category. These reclassified loans are to builders and developers of residential properties. Reclassifying these balances better aligned the loan categories with the management of credit risk. For the three and six months ended June 30, 2016, historic charge-offs and recoveries on these same loans have been reclassified, as well as the corresponding allowance for loan loss balances, average impaired loan balances, and new troubled debt restructurings.

United does not intend to sell nor believes 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, 2017 were primarily attributable to changes in interest rates and spread relationships. Management evaluates securities for other-than-temporary impairment on a quarterly basis, and more frequently when economic or market concerns warrant such evaluation. Consideration is given to the length of time and the extent to which the fair value has been less than cost, the financial condition and near-term prospects of the issuer, among other factors. In analyzing an issuer’s financial condition, management considers whether the securities are issued by the federal government or its agencies, whether downgrades by bond rating agencies have occurred, and industry analysts’ reports. No impairment charges were recognized during the three or six months ended June 30, 2017 or 2016. Realized gains and losses are derived using the specific identification method for determining the cost of securities sold.

In addition, management reviews all accruing substandard loans greater than $2 million to determine if the loan is impaired. A loan is considered impaired when, based on current events and circumstances, it is probable that all amounts due according to the original contractual terms of the loan will not be collected. All TDRs are considered impaired regardless of accrual status. Impairment is measured based on the present value of expected future cash flows, discounted at the loan’s effective interest rate, the loan’s observable market price, or the fair value of the collateral if the loan is collateral dependent. A specific reserve is established for impaired loans for the amount of calculated impairment. Interest payments received on impaired nonaccrual loans are applied as a reduction of the recorded investment in the loan. For impaired loans not on nonaccrual status, interest is accrued according to the terms of the loan agreement. Loans are evaluated for impairment quarterly and specific reserves are established in the allowance for loan losses for any measured impairment. Each quarter, management prepares an analysis of the allowance for credit losses to determine the appropriate balance that measures and quantifies the amount of probable incurred losses in the loan portfolio and unfunded loan commitments. The allowance is comprised of specific reserves on individually impaired loans, which are determined as described above, and general reserves which are determined based on historical loss experience as adjusted for current trends and economic conditions multiplied by a loss emergence period factor. Management calculates the loss emergence period for each pool of loans based on the weighted average length of time between the date a loan first exceeds 30 days past due and the date the loan is charged off. On junior lien home equity loans, management has limited ability to monitor the delinquency status of the first lien unless the first lien is also held by United. As a result, management applies the weighted average historical loss factor for this category and appropriately adjusts it to reflect the increased risk of loss from these credits. Management carefully reviews the resulting loss factors for each category of the loan portfolio and evaluates whether qualitative adjustments are necessary to take into consideration recent credit trends such as increases or decreases in past due, nonaccrual, criticized and classified loans, and other macro environmental factors such as changes in unemployment rates, lease vacancy rates and trends in property values and absorption rates. Management believes that its method of determining the balance of the allowance for credit losses provides a reasonable and reliable basis for measuring and reporting losses that are incurred in the loan portfolio as of the reporting date. When a loan officer determines that a loan is uncollectible, he or she is responsible for recommending that the loan be placed on nonaccrual status, evaluating the loan for impairment, and, if necessary, fully or partially charging off the loan. Full or partial charge-offs may also be recommended by the Collections Department, the Special Assets Department, the Loss Mitigation Department and the Foreclosure/OREO Department. Nonaccrual real estate loans are generally charged down to fair value less costs to sell at the time they are placed on nonaccrual status. Commercial and consumer asset quality committees meet monthly to review charge-offs that have occurred during the previous month. Participants include the Chief Credit Officer, Senior Risk Officers, Senior Credit Officers, and Regional Credit Managers. Generally, closed-end retail loans (installment and residential mortgage loans) past due 90 cumulative days are written down to their collateral value less estimated selling costs. Open-end (revolving) unsecured retail loans which are past due 90 cumulative days from their contractual due date are generally charged-off.

United committed to lend additional amounts totaling up to $95,000 at both June 30, 2017 and December 31, 2016 to customers with outstanding loans that are classified as TDRs. The modification of the TDR terms included one or a combination of the following: a reduction of the stated interest rate of the loan or an extension of the amortization period that would not otherwise be considered in the current market for new debt with similar risk characteristics; a restructuring of the borrower’s debt into an “A/B note structure” where the A note would fall within the borrower’s ability to pay and the remainder would be included in the B note; a mandated bankruptcy restructuring; or interest-only payment terms greater than 90 days where the borrower is unable to amortize the loan. Modified PCI loans are not accounted for as TDRs because they are not separated from the pools, and as such are not classified as impaired loans. Loans modified under the terms of a TDR during the three and six months ended June 30, 2017 and 2016 are presented in the table below.

United’s policy is to place loans on nonaccrual status when, in the opinion of management, the principal and interest on a loan is not likely to be repaid in full or when the loan becomes 90 days past due and is not well secured and in the process of collection. When a loan is classified on nonaccrual status, interest previously accrued but not collected is reversed against current interest revenue. Principal and interest payments received on a nonaccrual loan are applied to reduce the loan’s recorded investment. PCI loans are considered past due or delinquent when the contractual principal or interest due in accordance with the terms of the loan agreement remains unpaid after the due date of the scheduled payment. However, these loans are considered to be performing, even though they may be contractually past due, as any non-payment of contractual principal or interest is considered in the periodic re-estimation of expected cash flows and is included in the resulting recognition of current period loan loss provision or future period yield adjustments. The accrual of interest is discontinued on PCI loans if management can no longer reliably estimate future cash flows on the loan. No PCI loans were classified as nonaccrual at June 30, 2017 or December 31, 2016 as the carrying value of the respective loan or pool of loans cash flows were considered estimable and probable of collection. Therefore, interest revenue, through accretion of the difference between the carrying value of the loans and the expected cash flows, is being recognized on all PCI loans. The gross additional interest revenue that would have been earned if the loans classified as nonaccrual had performed in accordance with the original terms was approximately $246,000 and $170,000 for the three months ended June 30, 2017 and 2016, respectively, and $523,000 and $425,000 for the six months ended June 30, 2017 and 2016, respectively.

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: Watch. Substandard. Doubtful. Loss. Consumer Purpose Loans. Loans not meeting the criteria above that are analyzed individually as part of the above described process are considered to be pass rated loans.

Earnings Per Share [Abstract]
Earnings Per Share	Note 7 – Earnings Per Share United is required to report on the face of the consolidated statement of income, earnings per common share with and without the dilutive effects of potential common stock issuances from instruments such as options, convertible securities and warrants. Basic earnings per common share is based on the weighted average number of common shares outstanding during the period while the effects of potential common shares outstanding during the period are included in diluted earnings per common share. During the six months ended June 30, 2016, United accrued dividends of $21,000 on its Series H preferred stock. The Series H preferred stock was redeemed in the first quarter of 2016; accordingly, United did not accrue any dividends in 2017 or the second quarter of 2016. The following table sets forth the computation of basic and diluted earnings per share for the periods indicated (in thousands, except per share data) Three Months Ended Six Months Ended June 30, June 30, 2017 2016 2017 2016 Net income available to common shareholders $ 28,267 $ 25,266 $ 51,791 $ 47,540 Weighted average shares outstanding: Basic 71,810 72,202 71,798 72,187 Effect of dilutive securities Stock options 10 5 11 4 Diluted 71,820 72,207 71,809 72,191 Net income per common share: Basic $ .39 $ .35 $ .72 $ .66 Diluted $ .39 $ .35 $ .72 $ .66 At June 30, 2017, United had the following potentially dilutive stock options and warrants outstanding: a warrant to purchase 219,909 shares of common stock at $61.40 per share; 63,404 shares of common stock issuable upon exercise of stock options granted to employees with a weighted average exercise price of $25.45; and 595,188 shares of common stock issuable upon the vesting of restricted stock unit awards. At June 30, 2016, United had the following potentially dilutive stock options and warrants outstanding: a warrant to purchase 219,909 shares of common stock at $61.40 per share; 187,541 shares of common stock issuable upon exercise of stock options granted to employees with a weighted average exercise price of $77.65; and 581,760 shares of common stock issuable upon the vesting of restricted stock unit awards.

Derivatives and Hedging Activities [Abstract]
Derivatives and Hedging Activities	Note 8 – 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 primarily by managing the amount, sources, and duration of its investment securities portfolio and wholesale funding and through the use of derivative financial instruments. Specifically, United enters into derivative financial instruments to manage 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. In conjunction with the FASB’s fair value measurement guidance, United made an accounting policy election to measure the credit risk of its derivative financial instruments that are subject to master netting agreements on a gross basis. 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 sheet (in thousands) Derivatives designated as hedging instruments under ASC 815 Fair Value Interest Rate Products Balance Sheet June 30, December 31, Fair value hedge of corporate bonds Derivative assets $ 47 $ 265 $ 47 $ 265 Fair value hedge of brokered CDs Derivative liabilities $ 1,713 $ 1,980 $ 1,713 $ 1,980 Derivatives not designated as hedging instruments under ASC 815 Fair Value Interest Rate Products Balance Sheet June 30, 2017 December 31, 2016 Customer derivative positions Derivative assets $ 4,499 $ 5,266 Dealer offsets to customer derivative positions Derivative assets 4,641 3,869 Mortgage banking - loan commitment Derivative assets 1,424 1,552 Mortgage banking - forward sales commitment Derivative assets 119 534 Bifurcated embedded derivatives Derivative assets 10,432 10,225 Interest rate caps Derivative assets 478 - Offsetting positions for de-designated hedges Derivative assets - 1,977 $ 21,593 $ 23,423 Customer derivative positions Derivative liabilities $ 3,327 $ 3,897 Dealer offsets to customer derivative positions Derivative liabilities 4,723 5,328 Risk participations Derivative liabilities 21 26 Mortgage banking - forward sales commitment Derivative liabilities 119 96 Dealer offsets to bifurcated embedded derivatives Derivative liabilities 14,030 14,341 De-designated hedges Derivative liabilities 327 1,980 $ 22,547 $ 25,668 Customer derivative positions are between United and certain commercial loan customers with offsetting positions to dealers under a back-to-back swap/cap program. United also has three interest rate swap contracts that are not designated as hedging instruments but are economic hedges of market-linked brokered certificates of deposit. The market-linked brokered certificates of deposit contain embedded derivatives that are bifurcated from the host instruments and are marked to market through earnings. The fair value marks on the market linked swaps and the bifurcated embedded derivatives tend to move in opposite directions with changes in 90-day LIBOR and therefore provide an economic hedge. To accommodate customers, United occasionally enters into credit risk participation agreements with counterparty banks to accept a portion of the credit risk related to interest rate swaps. This allows customers to execute an interest rate swap with one bank while allowing for the distribution of the credit risk among participating members. Credit risk participation agreements arise when United contracts with other financial institutions, as a guarantor, to share credit risk associated with certain interest rate swaps. These agreements provide for reimbursement of losses resulting from a third party default on the underlying swap. These transactions are typically executed in conjunction with a participation in a loan with the same customer. Collateral used to support the credit risk for the underlying lending relationship is also available to offset the risk of the credit risk participation. 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. Most of this hedging activity is executed on a matched basis, with a loan sale commitment hedging a specific loan. The commitments to originate residential mortgage loans and forward loan sales commitments are freestanding derivative instruments. Beginning late in the third quarter of 2016 for newly originated mortgage loans, United began to account for the underlying 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 and other related fee income in the consolidated statement of income. In the second quarter of 2017, United purchased interest rate caps with a notional amount of $200 million to serve as an economic macro hedge of exposure to rising interest rates. Cash Flow Hedges of Interest Rate Risk At June 30, 2017 and December 31, 2016 United did not have any active cash flow hedges. Changes in balance sheet composition and interest rate risk position made cash flow hedges no longer necessary as protection against rising interest rates. The loss remaining in other comprehensive income on the de-designated swaps is being amortized into earnings over the original term of the swaps as the forecasted transactions that the swaps were originally designated to hedge are still expected to occur. United expects that $591,000 will be reclassified as an increase to interest expense over the next twelve months related to these cash flow hedges. The table below presents the effect of cash flow hedges on the consolidated statement of income for the periods indicated (in thousands) Amount of Gain (Loss) Gain (Loss) Reclassified from Gain (Loss) Recognized in Income on 2017 2016 Location 2017 2016 Location 2017 2016 Three Months Ended June 30, Interest rate swaps $ - $ - Interest expense $ (177 ) $ (460 ) Interest expense $ - $ - Six Months Ended June 30, Interest rate swaps $ - $ - Interest expense $ (590 ) $ (960 ) Interest expense $ - $ - 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 swaps to manage its exposure to changes in fair value on these instruments attributable to changes in interest rates. Interest rate swaps designated as fair value hedges of brokered deposits involve the receipt of fixed-rate amounts from a counterparty in exchange for United making variable rate payments over the life of the agreements without the exchange of the underlying notional amount. Interest rate swaps designated as fair value hedges of fixed-rate investments involve the receipt of variable-rate payments from a counterparty in exchange for United making fixed-rate payments over the life of the instrument without the exchange of the underlying notional amount. At June 30, 2017, United had four interest rate swaps with a notional amount of $40.7 million that were designated as fair value hedges of interest rate risk and were pay-variable / receive-fixed swaps hedging the changes in the fair value of fixed-rate brokered time deposits resulting from changes in interest rates. Also at June 30, 2017, United had one interest rate swap with a notional value of $30 million that was designated as a pay-fixed / receive-variable fair value hedge of changes in the fair value of a fixed-rate corporate bond. At December 31, 2016, United had one interest rate swap with an aggregate notional amount of $12.8 million that was designated as a fair value hedge of interest rate risk and was pay-variable / receive-fixed, hedging the changes in the fair value of fixed-rate brokered time deposits resulting from changes in interest rates. Also at December 31, 2016, United had one interest rate swap with a notional value of $30 million that was designated as a pay-fixed / receive-variable fair value hedge of changes in the fair value of a fixed-rate corporate bond. 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. During the three and six months ended June 30, 2017, United recognized net losses of $327,000 and $452,000, respectively, related to ineffectiveness in the fair value hedging relationships. During the three and six months ended June 30, 2016, United recognized net gains of $216,000 and $854,000, respectively, related to ineffectiveness in the fair value hedging relationships. United also recognized net reductions of interest expense of $65,000 and $97,000, respectively, for the three and six months ended June 30, 2017 and net reductions of interest expense of $448,000 and $1.24 million, respectively, for the three and six months ended June 30, 2016 related to fair value hedges of brokered time deposits, which includes net settlements on the derivatives. United recognized reductions of interest revenue on securities during the three and six months ended June 30, 2017 of $80,000 and $173,000, respectively, and reductions of interest revenue on securities during the three and six months ended June 30, 2016 of $117,000 and $246,000, respectively, related to fair value hedges of corporate bonds.

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 and such gains and losses are included in the amount of reported ineffectiveness gains or losses.

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. As of June 30, 2017, collateral totaling $19.1 million was pledged toward derivatives in a liability position. United’s agreements with each of its derivative counterparties contain a provision where 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 contain a provision where 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.

Stock-Based Compensation

Stock-Based Compensation	6 Months Ended

Disclosure Of Compensation Related Costs, Share-Based Payments [Abstract]
Stock-Based Compensation	Note 9 – Stock-Based Compensation United has an equity compensation plan that allows for grants of incentive stock options, nonqualified stock options, restricted stock and restricted stock unit awards (also referred to as “nonvested stock” awards), stock awards, performance share awards or stock appreciation rights. Options granted under the plan can 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, restricted stock and restricted stock unit awards provide for accelerated vesting if there is a change in control (as defined in the plan). Through June 30, 2017, incentive stock options, nonqualified stock options, restricted stock and restricted stock unit awards, base salary stock grants and performance share awards have been granted under the plan. As of June 30, 2017, 2.16 million additional shares remained available for grant under the plan. The following table shows stock option activity for the first six months of 2017. Options Shares Weighted- Weighted- Aggregate Outstanding at December 31, 2016 72,665 $ 34.34 Expired (1,538 ) 147.60 Cancelled (7,723 ) 84.78 Outstanding at June 30, 2017 63,404 25.45 3.5 $ 346 Exercisable at June 30, 2017 57,154 26.44 3.1 275 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, 2017 and 2016. United’s stock option exercise patterns were significantly impacted by the past economic downturn, which rendered most of United’s outstanding options worthless to the grantee. Therefore, historical exercise patterns do not provide a reasonable basis for determining the expected life of new option grants. United therefore uses the formula provided in ASC 718-10-S99 to determine the expected life of options. United recognized $15,000 in compensation expense related to stock options during both the six months ended June 30, 2017 and 2016. The amount of compensation expense was determined based on the fair value of the options at the time of grant, multiplied by the number of options granted that were expected to vest, which was then amortized over the vesting period. No options were exercised during the first six months of 2017 or 2016. The table below presents restricted stock units activity for the first six months of 2017. Restricted Stock Unit Awards Shares Weighted- Weighted- Aggregate Outstanding at December 31, 2016 690,970 $ 18.60 Granted 37,737 27.30 Vested (123,554 ) 17.08 $ 3,557 Cancelled (9,965 ) 19.99 Outstanding at June 30, 2017 595,188 19.58 2.5 16,546 Compensation expense for restricted stock units is based on the fair value of restricted stock unit awards at the time of grant, which is equal to the value of United’s common stock on the date of grant. United recognizes the impact of forfeitures as they occur. The value of restricted stock unit awards is amortized into expense over the vesting period. For the six months ended June 30, 2017 and 2016, expense of $3.02 million and $1.76 million, respectively, was recognized related to employee restricted stock unit awards. Of the expense recognized related to restricted stock unit awards during the six months ended June 30, 2017, $696,000 relates to the modification of existing awards resulting from an acceleration of vesting of unvested awards due to retirement which was recognized in merger-related and other charges. The remaining expense of $2.33 million was recognized in compensation expense. In addition, for the six months ended June 30, 2017 and 2016, $113,000 and $51,000, respectively, was recognized in other operating expense for restricted stock unit awards granted to members of United’s board of directors. As of June 30, 2017, there was $7.72 million of unrecognized expense related to non-vested stock options and restricted stock unit awards granted under the plan. That cost is expected to be recognized over a weighted-average period of 2.51 years.

Equity [Abstract]
Common and Preferred Stock Issued / Common Stock Issuable	Note 10 – Common and Preferred Stock Issued / Common Stock Issuable United sponsors a Dividend Reinvestment and Share Purchase Plan (“DRIP”) that allows participants who already own United’s common stock to purchase additional shares directly from United. The DRIP also allows participants to automatically reinvest their quarterly dividends in additional shares of common stock without a commission. In the six months ended June 30, 2017 and 2016, 1,714 shares and 1,775 shares, respectively, were issued through the DRIP. In addition, United has an Employee Stock Purchase Program (“ESPP”) that allows eligible employees to purchase shares of common stock at a 10% discount, with no commission charges. During the first six months of 2017 and 2016, United issued 6,855 shares and 8,585 shares, respectively, through the ESPP. United offers its common stock as an investment option in its deferred compensation plan. United also allows for the deferral of restricted stock unit awards. The common stock component of the deferred compensation plan is accounted for as an equity instrument and is reflected in the consolidated financial statements as common stock issuable. The deferred compensation plan does not allow for diversification once an election is made to invest in United’s common stock and settlement must be accomplished in shares at the time the deferral period is completed. At June 30, 2017 and December 31, 2016, 550,449 and 519,874 shares of common stock, respectively, were issuable under the deferred compensation plan. On March 22, 2016, United announced that its Board of Directors had authorized a program to repurchase up to $50 million of United’s outstanding common stock through December 31, 2017. Under the program, the shares may be repurchased periodically in open market transactions at prevailing market prices, in privately negotiated transactions, or by other means in accordance with federal securities laws. The actual timing, number and value of shares repurchased under the program depends on a number of factors, including the market price of United’s common stock, general market and economic conditions, and applicable legal requirements. During the first six months of 2017, United did not repurchase any shares under the program. As of June 30, 2017, $36.3 million of United’s outstanding common stock may be repurchased under the program.

Income Tax Disclosure [Abstract]
Income Taxes	Note 11 – Income Taxes The income tax provision for the three and six months ended June 30, 2017 was $16.5 million and $35.0 million, respectively, which represents an effective tax rate of 36.9% and 40.3%, respectively, for each period. The income tax provision for the three and six months ended June 30, 2016 was $15.4 million and $29.0 million, respectively, which represents an effective tax rate of 37.9% for both periods. Upon reversal of United’s former full deferred tax valuation allowance in 2013, certain disproportionate tax effects were retained in accumulated other comprehensive income (loss). During the first quarter of 2017, with the maturity and termination of certain dedesignated cash flow hedges, the disproportionate tax effect associated with these hedges was reversed and recorded as a tax expense of $3.40 million, which was the primary reason for the increase in the effective tax rate compared to the first six months of 2016. At June 30, 2017 and December 31, 2016, United maintained a valuation allowance on its net deferred tax asset of $4.09 million and $3.88 million, respectively. Management assesses the valuation allowance recorded against its net deferred tax asset at each reporting period. The determination of whether a valuation allowance for its net deferred tax asset is appropriate is subject to considerable judgment and requires an evaluation of all the positive and negative evidence. United evaluated the need for a valuation allowance at June 30, 2017. Based on the assessment of all the positive and negative evidence, management concluded that it is more likely than not that nearly all of its net deferred tax asset will be realized based upon future taxable income. The remaining valuation allowance of $4.09 million is related to specific state income tax credits that have short carryforward periods and are expected to expire unused. The valuation allowance could fluctuate in future periods based on the assessment of the positive and negative evidence. Management's conclusion at June 30, 2017 that it was more likely than not that the net deferred tax asset of $120 million will be realized is based upon internal forecasts that consider historical performance, various internal estimates and assumptions, as well as certain external data all of which management believes to be reasonable although inherently subject to significant judgment. If actual results differ significantly from the current estimates of future taxable income, even if caused by adverse macro-economic conditions, the valuation allowance may need to be increased for some or all of its net deferred tax asset. Such an increase to the net deferred tax asset valuation allowance could have a material adverse effect on United’s financial condition and results of operations. United is subject to income taxation in the United States and various state jurisdictions. United’s federal and state income tax returns are filed on a consolidated basis. Currently, no years for which United filed a federal income tax return are under examination by the IRS, and there are no state tax examinations currently in progress. United is no longer subject to income tax examinations from state and local income tax authorities for years before 2013. Although it is not possible to know the ultimate outcome of future examinations, management believes that the liability recorded for uncertain tax positions is appropriate. At June 30, 2017 and December 31, 2016, unrecognized income tax benefits totaled $4.11 million and $3.89 million, respectively.

Assets and Liabilities Measured

Assets and Liabilities Measured at Fair Value	6 Months Ended
	Jun. 30, 2017
Fair Value [Abstract]
Assets and Liabilities Measured at Fair Value	Note 12 – 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 Level 2 Level 3 In instances where the determination of the fair value measurement is based on inputs from different levels of the fair value hierarchy, the level in the fair value hierarchy within which the entire fair value measurement falls is based on the lowest level input that is significant to the fair value measurement in its entirety. United’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment, and considers factors specific to the asset or liability. The following is a description of the valuation methodologies used for assets and liabilities recorded at fair value. Securities Available-for-Sale Investment securities available-for-sale 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, United States Department of Treasury (“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 asset-backed securities in less liquid markets. Securities classified as Level 3 are valued based on estimates obtained from broker-dealers and 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 Beginning in the third quarter of 2016, United elected the fair value option for newly originated mortgage loans held for sale. United elected the fair value option for its portfolio of 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). Loans United does not record loans at fair value on a recurring basis. However, from time to time, a loan is considered impaired and an allowance for loan losses is established. Loans for which it is probable that payment of interest and principal will not be made in accordance with the contractual terms of the loan agreement are considered impaired. Once a loan is identified as individually impaired, management measures impairment based on the present value of expected future cash flows discounted at the loan's effective interest rate, except that as a practical expedient, a creditor may measure impairment based on a loan's observable market price, or the fair value of the collateral if repayment of the loan is dependent upon the sale of the underlying collateral. Those impaired loans not requiring an allowance represent loans for which the fair value of the expected repayments or collateral exceed the recorded investments in such loans. In accordance with ASC 820, Fair Value Measures and Disclosures Derivative Financial Instruments United uses interest rate swaps and interest rate floors to manage its 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. To comply with the provisions of ASC 820, United incorporates credit valuation adjustments to appropriately reflect both its own nonperformance risk and 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, mutual puts, and guarantees. Although management has determined that the majority of the inputs used to value its derivatives fall within Level 2 of the fair value hierarchy, the credit valuation adjustments associated with its derivatives utilize Level 3 inputs, such as estimates of current credit spreads to evaluate the likelihood of default by itself and its counterparties. However, as of June 30, 2017, management had assessed the significance of the effect of the credit valuation adjustments on the overall valuation of its derivative positions and has determined that the credit valuation adjustments are not significant to the overall valuation of its derivatives. Derivatives classified as Level 3 included structured derivatives for which broker quotes, used as a key valuation input, were not observable consistent with a Level 2 disclosure. The fair value of risk participations incorporates Level 3 inputs to evaluate the likelihood of customer default. The fair value of interest rate lock commitments, which is related to mortgage loan commitments, is categorized as Level 3 based on unobservable inputs for commitments that United does not expect to fund. Servicing Rights for SBA/USDA Loans United recognizes servicing rights upon the sale of Small Business Administration and United States Department of Agriculture (“SBA/USDA”) loans sold with servicing retained. Management has elected to carry this asset at fair value. Given the nature of the asset, the key valuation inputs are unobservable and management classifies this asset as Level 3. Residential Mortgage Servicing Rights United recognizes servicing rights upon the sale of residential mortgage loans sold with servicing retained. Effective January 1, 2017, management has elected to carry this asset at fair value. Given the nature of the asset, the key valuation inputs are unobservable and management classifies this asset as Level 3. The cumulative effect adjustment of this election to retained earnings, net of income tax effect, was $437,000.

At December 31, 2016, mortgage loans held for sale for which the fair value option was elected had an aggregate fair value and outstanding principal balance of $27.9 million and $27.6 million, respectively. Interest income on these loans is calculated based on the note rate of the loan and is recorded in interest revenue. During the three and six months ended June 30, 2017, net gains resulting from changes in fair value of these loans of $192,000 and $444,000, respectively, were recorded in mortgage loan and other related fees. These 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. During the three and six months ended June 30, 2016, no such gains were recorded. 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, 2017 and December 31, 2016, for which a nonrecurring fair value adjustment was recorded during the year-to-date periods presented (in thousands) June 30, 2017 Level 1 Level 2 Level 3 Total Loans $ - $ - $ 8,625 $ 8,625 December 31, 2016 Loans $ - $ - $ 7,179 $ 7,179 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 impaired loans that are collateral dependent are generally written down to 80% of appraised value which considers the estimated costs to sell. Specific reserves are established for impaired loans based on appraised value of collateral or discounted cash flows, although only those specific reserves based on the fair value of collateral are considered nonrecurring fair value adjustments. 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) Carrying Fair Value Level June 30, 2017 Amount Level 1 Level 2 Level 3 Total Assets: Securities held to maturity $ 312,002 $ - $ 316,583 $ - $ 316,583 Loans, net 6,981,432 - - 6,898,237 6,898,237 Mortgage loans held for sale 1,602 - 1,627 - 1,627 Liabilities: Deposits 8,735,735 - 8,736,957 - 8,736,957 Federal Home Loan Bank advances 669,065 - 668,997 - 668,997 Long-term debt 175,363 - - 176,721 176,721 December 31, 2016 Assets: Securities held to maturity $ 329,843 $ - $ 333,170 $ - $ 333,170 Loans, net 6,859,214 - - 6,824,229 6,824,229 Mortgage loans held for sale 1,987 - 2,018 - 2,018 Residential mortgage servicing rights 4,372 - - 5,175 5,175 Liabilities: Deposits 8,637,558 - 8,635,811 - 8,635,811 Federal Home Loan Bank advances 709,209 - 709,174 - 709,174 Long-term debt 175,078 - - 175,750 175,750

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Note 13 – 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 many 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, December 31, 2017 2016 Financial instruments whose contract amounts represent credit risk: Commitments to extend credit $ 1,675,090 $ 1,542,186 Letters of credit 28,108 26,862 United’s wholly-owned bank subsidiary, United Community Bank (the“Bank”), holds minor investments in certain limited partnerships for Community Reinvestment Act purposes. As of June 30, 2017, the Bank had invested $3.81 million in these limited partnerships and had committed to fund an additional $5.69 million related to future capital calls. 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]
Mergers and Acquisitions	Note 14 – Mergers and Acquisitions Four Oaks Fincorp, Inc. On June 27, 2017, United announced that it had reached a definitive merger agreement to acquire Four Oaks Fincorp, Inc. (“FOFN”) and its wholly-owned bank subsidiary, Four Oaks Bank & Trust Company. As of March 31, 2017, FOFN had total assets of $737 million, loans of $513 million and deposits of $560 million. Four Oaks Bank & Trust Company, which currently operates 14 banking offices in the Raleigh, North Carolina metropolitan statistical area, will merge into and operate under the brand of United Community Bank, United’s wholly-owned bank subsidiary. Under the terms of the merger agreement, which has been unanimously approved by the Boards of Directors of both companies, FOFN shareholders will receive .6178 shares of United common stock and $1.90 for each share of FOFN common stock. Based on United’s closing price of $26.48 per share on June 23, 2017, the aggregate deal value is approximately $124 million. The merger, which is subject to regulatory approval, the approval of shareholders of FOFN, and other customary conditions, is expected to close in the fourth quarter of 2017. HCSB Financial Corporation On July 31, 2017, United completed its previously announced acquisition of HCSB Financial Corporation (“HCSB”) and its wholly-owned bank subsidiary, Horry County State Bank. As of March 31, 2017, HCSB had total assets of $384 million, loans of $229 million and deposits of $322 million. Horry County State Bank, which operated eight branches in the Myrtle Beach-Conway-North Myrtle Beach area of South Carolina, will operate under the HCSB brand until system conversions are completed in the fourth quarter of 2017, at which time it will begin to operate as United Community Bank. Under the terms of the merger agreement, HCSB shareholders received .0050 shares of United common stock for each share of HCSB common stock, or an aggregate of approximately $69 million, based on United’s closing price of $27.76 on July 31, 2017. 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 disclosures required by ASC 805-10-50, such as the fair value of assets acquired and supplemental pro forma information, which will be disclosed in subsequent filings.

Accounting Policies [Abstract]
Accounting Policies	Accounting Policies The accounting and financial reporting policies of United Community Banks, Inc. (“United”) and its subsidiaries conform to accounting principles generally accepted in the United States (“GAAP”) and reporting guidelines of banking regulatory authorities and regulators. The accompanying interim consolidated financial statements have not been audited. All material intercompany balances and transactions have been eliminated. A more detailed description of United’s accounting policies is included in its Annual Report on Form 10-K for the year ended December 31, 2016. Effective January 1, 2017, management elected to begin measuring residential mortgage servicing rights at fair value. The cumulative effect adjustment of this election to retained earnings, net of income tax effect, was $437,000. 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 statement. The results for interim periods are not necessarily indicative of results for the full year or any other interim periods. Certain 2016 amounts have been reclassified to conform to the 2017 presentation. As discussed in the Form 10-K for the year ended December 31, 2016, certain loan balances previously shown as retail loans were reclassified to several commercial categories to better align the reporting with the business purpose or underlying credit risk of the loans, rather than the collateral type. The reclassifications moved residential mortgages and home equity lines from the residential mortgage and home equity lines of credit categories to the owner-occupied and income-producing commercial real estate categories. Although these loans were secured by one-to-four family residential properties, their purpose was commercial since they included residential home rental property and business purpose loans secured by the borrower’s primary residence. In addition, residential construction loans were reclassified to the commercial construction category. These reclassified loans are to builders and developers of residential properties. Reclassifying these balances better aligned the loan categories with the management of credit risk. For the three and six months ended June 30, 2016, historic charge-offs and recoveries on these same loans have been reclassified, as well as the corresponding allowance for loan loss balances, average impaired loan balances, and new troubled debt restructurings.
