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, 2015. 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 2015 amounts have been reclassified to conform to the 2016 presentation.

Acquisitions	Note 3 – Acquisitions Acquisition of Tidelands Bancshares, Inc. On July 1, 2016, United completed the acquisition of Tidelands Bancshares, Inc. (“Tidelands”) and its wholly-owned bank subsidiary Tidelands Bank. Tidelands operated seven branches in coastal South Carolina. In connection with the acquisition, United acquired $440 million of assets and assumed $440 million of liabilities. Under the terms of the merger agreement, Tidelands shareholders received cash equal to $0.52 per common share, or an aggregate of $2.22 million. Additionally, at closing, United redeemed all of Tidelands’ fixed-rate cumulative preferred stock that was issued to the United States Department of the Treasury (the “Treasury”) under the Treasury’s Capital Purchase Program, plus unpaid dividends, for $8.98 million in aggregate. The fair value of consideration paid exceeded the fair value of the identifiable assets and liabilities acquired and resulted in the establishment of goodwill in the amount of $10.7 million, representing the intangible value of Tidelands’ business and reputation within the market it served. None of the goodwill recognized is expected to be deductible for income tax purposes. United will amortize the related core deposit intangible of $1.57 million using the sum-of-the-years-digits method over five years, which represents the expected useful life of the asset. As of the acquisition date, United assumed long-term debt obligations with an aggregate balance of $14.4 million and an aggregate fair value of $10.8 million related to Tidelands’ outstanding trust preferred securities and paid all amounts required to bring current the payment of interest (including deferred interest) on such trust preferred securities. The $8.25 million of debt related to Tidelands Statutory Trust I has a stated maturity date of March 30, 2036 and a rate equal to LIBOR plus 1.38%, which resets quarterly. The $6.19 million of debt related to Tidelands Statutory Trust II has a stated maturity date of June 30, 2038 and a rate equal to LIBOR plus 5.075%, which resets quarterly. United’s operating results for the period ended September 30, 2016 include the operating results of the acquired assets and assumed liabilities for the period subsequent to the acquisition date of July 1, 2016. The purchased assets and assumed liabilities were recorded at their acquisition date fair values and are summarized in the table below (in thousands) As Recorded Fair Value As Recorded by by Tidelands Adjustments (1) United Assets Cash and cash equivalents $ 13,121 $ - $ 13,121 Securities 65,676 (155 ) 65,521 Loans held for sale 139 3 142 Loans, net 317,938 (12,035 ) 305,903 Premises and equipment, net 19,133 (7,944 ) 11,189 Bank owned life insurance 16,917 - 16,917 Accrued interest receivable 1,086 (167 ) 919 Net deferred tax asset 73 15,639 15,712 Core deposit intangible - 1,570 1,570 Other real estate owned 9,881 (2,386 ) 7,495 Other assets 1,920 (164 ) 1,756 Total assets acquired $ 445,884 $ (5,639 ) $ 440,245 Liabilities Deposits $ 398,108 $ 1,765 $ 399,873 Repurchase agreements 10,000 155 10,155 Federal Home Loan Bank advances 13,000 354 13,354 Long-term debt 14,434 (3,668 ) 10,766 Other liabilities 11,587 (5,986 ) 5,601 Total liabilities assumed 447,129 (7,380 ) 439,749 Excess of assets acquired over liabilities assumed $ (1,245 ) Aggregate fair value adjustments $ 1,741 Total identifiable net assets $ 496 Consideration transferred Cash paid to redeem common stock 2,224 Cash paid to redeem preferred stock issued under the Treasury's Capital Purchase Program 8,985 Total fair value of consideration transferred 11,209 Goodwill $ 10,713 (1) The following table presents additional information related to the acquired loan portfolio at the acquisition date (in thousands) July 1, 2016 Accounted for pursuant to ASC 310-30: Contractually required principal and interest $ 50,660 Non-accretable difference 13,483 Cash flows expected to be collected 37,177 Accretable yield 2,113 Fair value $ 35,064 Excluded from ASC 310-30: Fair value $ 270,839 Gross contractual amounts receivable 302,331 Estimate of contractual cash flows not expected to be collected 3,859 Acquisition of Palmetto Bancshares, Inc. On September 1, 2015, United completed the acquisition of Palmetto Bancshares, Inc. (“Palmetto”) and its wholly-owned bank subsidiary The Palmetto Bank. Information related to the fair value of assets and liabilities acquired from Palmetto is included in United’s Annual Report on Form 10-K for the year ended December 31, 2015. During second quarter 2016, within the one year measurement period, United received additional information regarding the acquisition date fair values of premises and equipment and other real estate owned (“OREO”). As a result the provisional values assigned to the acquired premises and equipment and OREO have been adjusted to $17.0 million and $2.63 million, respectively, which represent a decrease of $640,000 and $497,000, respectively, from amounts previously disclosed. The tax effect of these adjustments was reflected as an increase to the deferred tax asset of $437,000, with the net amount of $700,000 reflected as an increase to goodwill. Acquisition of MoneyTree Corporation On May 1, 2015, United completed the acquisition of MoneyTree Corporation (“MoneyTree”) and its wholly-owned bank subsidiary, First National Bank. Information related to the fair value of assets and liabilities acquired from MoneyTree is included in United’s Annual Report on Form 10-K for the year ended December 31, 2015. Pro forma information The following table discloses the impact of the mergers with Tidelands, Palmetto and MoneyTree since their respective acquisition dates through September 30 of the year of acquisition. The table also presents certain pro forma information as if Tidelands had been acquired on January 1, 2015 and Palmetto and MoneyTree had been acquired on January 1, 2014. These results combine the historical results of the acquired entities 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 acquisition taken place in earlier years.

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 September 30, 2016 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 nine months ended September 30, 2016 or 2015. 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 nine months ended September 30, 2016 and 2015 (in thousands) Three Months Ended Nine Months Ended 2016 2015 2016 2015 Proceeds from sales $ 100,867 $ 137,702 $ 189,164 $ 274,519 Gross gains on sales $ 607 $ 328 $ 1,565 $ 1,880 Gross losses on sales (346 ) (3 ) (643 ) (3 ) Net gains on sales of securities $ 261 $ 325 $ 922 $ 1,877 Income tax expense attributable to sales $ 101 $ 121 $ 348 $ 724 The amortized cost and fair value of held-to-maturity and available-for-sale securities at September 30, 2016, by contractual maturity, are presented in the following table (in thousands) Available-for-Sale Held-to-Maturity Amortized Cost Fair Value Amortized Cost Fair Value US Treasuries: 1 to 5 years $ 65,957 $ 67,453 $ - $ - 5 to 10 years 74,543 77,421 - - 140,500 144,874 - - US Government agencies: 1 to 5 years 990 995 - - 5 to 10 years 18,180 18,443 - - More than 10 years 1,035 1,017 20,205 20,455 - - State and political subdivisions: Within 1 year 1,252 1,263 4,012 4,077 1 to 5 years 31,964 32,790 12,860 13,681 5 to 10 years 23,673 24,516 22,152 24,774 More than 10 years 6,112 6,317 18,887 18,863 63,001 64,886 57,911 61,395 Corporate bonds: 1 to 5 years 233,824 237,475 - - 5 to 10 years 72,416 74,584 - - More than 10 years 1,000 500 - - 307,240 312,559 - - Asset-backed securities: 1 to 5 years 17,250 17,459 - - 5 to 10 years 333,434 333,831 - - More than 10 years 144,602 144,143 - - 495,286 495,433 - - Other: More than 10 years 1,125 1,125 - - 1,125 1,125 - - Total securities other than mortgage-backed securities: Within 1 year 1,252 1,263 4,012 4,077 1 to 5 years 349,985 356,172 12,860 13,681 5 to 10 years 522,246 528,795 22,152 24,774 More than 10 years 153,874 153,102 18,887 18,863 Mortgage-backed securities 1,151,570 1,175,781 287,006 296,155 $ 2,178,927 $ 2,215,113 $ 344,917 $ 357,550 Expected maturities may differ from contractual maturities because issuers and borrowers may have the right to call or prepay obligations.

At September 30, 2016 and December 31, 2015, the remaining accretable fair value marks on loans acquired through a business combination and not accounted for under ASC 310-30 were $8.30 million and $7.03 million, respectively. In addition, indirect auto loans purchased at a premium outside of a business combination have a remaining premium of $11.8 million and $12.0 million, respectively, as of September 30, 2016 and December 31, 2015. The allowance for loan losses represents management’s estimate of probable incurred losses in the loan portfolio as of the end of the period. The allowance for unfunded commitments is included in other liabilities in the consolidated balance sheet. Combined, the allowance for loan losses and allowance for unfunded commitments are referred to as the allowance for credit losses.

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 had previously used eight quarters of historical loss experience look-back period to determine the loss factors to be used in the reserve calculation for loans evaluated in the aggregate. Beginning in the third quarter of 2016, management extended the look-back period to 17 quarters to better capture the full range of the loss cycle balanced with the availability of reliable historical data. The look-back period will be extended by one quarter each quarter going forward. Management weights each quarter in the look-back period equally to capture the full range of the cycle. Management believes the weightings are appropriate to measure the probable losses incurred within the loan portfolio. 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 and charged off. 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 consisting of the Chief Credit Officer, Senior Risk Officers and Senior Credit Officers meet monthly to review charge-offs that have occurred during the previous month. 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.

Nonaccrual loans include both homogeneous loans that are collectively evaluated for impairment and individually evaluated impaired loans. 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 covered 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 September 30, 2016 or December 31, 2015 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 $262,000 for the three months ended September 30, 2016 and 2015 and $686,000 for the nine months ended September 30, 2016 and 2015.

United committed to lend additional amounts totaling up to $55,000 and $224,000 as of September 30, 2016 and December 31, 2015, respectively, to customers with outstanding loans that are classified as TDRs. The modification of the terms of the TDRs 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.

Risk Ratings United categorizes commercial loans 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: 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. Based on the most recent analysis performed, the risk category of loans by class of loans is as follows (in thousands) Doubtful / As of September 30, 2016 Pass Watch (1) Substandard Loss Total Owner occupied commercial real estate $ 1,443,160 $ 19,613 $ 30,764 $ - $ 1,493,537 Income producing commercial real estate 1,054,769 2,622 23,269 - 1,080,660 Commercial & industrial 978,008 5,007 10,288 - 993,303 Commercial construction 381,336 1,333 997 - 383,666 Total commercial 3,857,273 28,575 65,318 - 3,951,166 Residential mortgage 1,007,944 7,470 33,801 - 1,049,215 Home equity lines of credit 685,670 26 5,272 - 690,968 Residential construction 359,126 4,871 9,828 - 373,825 Consumer installment 125,540 - 757 - 126,297 Indirect auto 463,186 - 2,908 - 466,094 Total loans, excluding PCI loans $ 6,498,739 $ 40,942 $ 117,884 $ - $ 6,657,565 Owner occupied commercial real estate $ 2,211 $ 3,379 $ 13,058 $ - $ 18,648 Income producing commercial real estate 12,667 10,028 1,938 - 24,633 Commercial & industrial 92 117 838 - 1,047 Commercial construction 1,594 299 3,302 - 5,195 Total commercial 16,564 13,823 19,136 - 49,523 Residential mortgage 722 666 4,563 - 5,951 Home equity lines of credit 6,419 - 969 - 7,388 Residential construction 2,588 1,281 635 - 4,504 Consumer installment 168 - 3 - 171 Indirect auto - - 8 - 8 Total PCI loans $ 26,461 $ 15,770 $ 25,314 $ - $ 67,545 As of December 31, 2015 Owner occupied commercial real estate $ 1,414,353 $ 24,175 $ 41,764 $ - $ 1,480,292 Income producing commercial real estate 771,792 4,151 20,015 - 795,958 Commercial & industrial 770,287 8,171 6,304 - 784,762 Commercial construction 335,571 3,069 1,296 - 339,936 Total commercial 3,292,003 39,566 69,379 - 3,400,948 Residential mortgage 985,109 5,070 35,308 - 1,025,487 Home equity lines of credit 589,749 24 6,345 - 596,118 Residential construction 335,341 3,813 11,423 - 350,577 Consumer installment 114,178 - 892 - 115,070 Indirect auto 453,935 - 1,987 - 455,922 Total loans, excluding PCI loans $ 5,770,315 $ 48,473 $ 125,334 $ - $ 5,944,122 Owner occupied commercial real estate $ 1,811 $ 6,705 $ 4,809 $ 349 $ 13,674 Income producing commercial real estate 9,378 5,766 12,627 - 27,771 Commercial & industrial 17 83 505 50 655 Commercial construction 1,698 6 438 - 2,142 Total commercial 12,904 12,560 18,379 399 44,242 Residential mortgage - 410 3,766 - 4,176 Home equity lines of credit 214 - 1,474 - 1,688 Residential construction 345 39 227 512 1,123 Consumer installment 1 - 40 - 41 Indirect auto - - 49 - 49 Total PCI loans $ 13,464 $ 13,009 $ 23,935 $ 911 $ 51,319 (1)

Earnings Per Share [Abstract]
Earnings Per Share	Note 8 – 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 nine months ended September 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 for the third quarter of 2016. The preferred stock dividends were subtracted from net income in order to arrive at net income available to common shareholders. During the three and nine months ended September 30, 2015, United accrued dividends of $25,000 and $42,000, respectively, on its Series H preferred stock. 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 Nine Months Ended September 30, September 30, 2016 2015 2016 2015 Net income available to common shareholders $ 25,874 $ 17,862 $ 73,414 $ 53,328 Weighted average shares outstanding: Basic 71,556 66,294 71,992 63,297 Effect of dilutive securities Stock options 5 6 4 5 Diluted 71,561 66,300 71,996 63,302 Net income per common share: Basic $ .36 $ .27 $ 1.02 $ .84 Diluted $ .36 $ .27 $ 1.02 $ .84 At September 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; 185,688 shares of common stock issuable upon exercise of stock options granted to employees with a weighted average exercise price of $77.63; and 674,862 shares of common stock issuable upon completion of vesting of restricted stock unit awards. At September 30, 2015, 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; 255,229 shares of common stock issuable upon exercise of stock options granted to employees with a weighted average exercise price of $90.10; and 735,280 shares of common stock issuable upon completion of vesting of restricted stock unit awards.

Derivatives and Hedging Activities [Abstract]
Derivatives and Hedging Activities	Note 9 – 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 its 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 September 30, December 31, Fair value hedge of corporate bonds Derivative assets $ - $ 31 $ - $ 31 Fair value hedge of brokered CD's Derivative liabilities $ 1,070 $ 2,169 Fair value hedge of corporate bonds Derivative liabilities 2,114 - $ 3,184 $ 2,169 Derivatives not designated as hedging instruments under ASC 815 Fair Value Interest Rate Products Balance Sheet September 30, December 31, Customer swap positions Derivative assets $ 16,018 $ 6,185 Dealer offsets to customer swap positions Derivative assets - 31 Mortgage banking - loan commitment Derivative assets 1,072 188 Mortgage banking - forward sales commitment Derivative assets 3 1 Bifurcated embedded derivatives Derivative assets 3,793 9,230 Offsetting positions for de-designated cash flow hedges Derivative assets 4,577 4,416 $ 25,463 $ 20,051 Customer swap positions Derivative liabilities $ - $ 31 Dealer offsets to customer swap positions Derivative liabilities 16,170 6,339 Risk participations Derivative liabilities 38 - Mortgage banking - forward sales commitment Derivative liabilities 70 22 Dealer offsets to bifurcated embedded derivatives Derivative liabilities 8,507 15,794 De-designated cash flow hedges Derivative liabilities 4,579 4,470 $ 29,364 $ 26,656 Customer swap positions are between United and certain commercial loan customers with offsetting positions to dealers under a back-to-back swap 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 marked to market through earnings. The 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, the Company is subject to the risk of variability in market prices. United also enters into forward sale agreements to mitigate risk and to protect the expected gain on the eventual loan sale. Most of this activity is 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. Cash Flow Hedges of Interest Rate Risk At September 30, 2016 and December 31, 2015 United did not have any active cash flow hedges. Changes in United’s balance sheet composition and interest rate risk position made cash flow hedges no longer necessary as protection against rising interest rates and as a result, United de-designated its former cash flow hedges. 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 $1.21 million 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 2016 2015 Location 2016 2015 Location 2016 2015 Three Months Ended September 30, Interest rate swaps $ - $ - Interest expense $ (466 ) $ (550 ) Interest expense $ - $ - Nine Months Ended September 30, Interest rate swaps $ - $ (471 ) Interest expense $ (1,426 ) $ (1,430 ) Interest expense $ - $ (7 ) 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 September 30, 2016, United had one interest rate swap with a notional amount of $12.8 million that was designated as a fair value hedge of interest rate risk and was a pay-variable / receive-fixed swap hedging the changes in the fair value of fixed-rate brokered time deposits resulting from changes in interest rates. Also at September 30, 2016, United had one interest rate swap with a notional 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, 2015, United had 13 interest rate swaps with an aggregate notional amount of $156 million that were designated as fair value hedges of interest rate risk. These contracts were pay-variable / receive-fixed swaps hedging changes in the fair value of fixed-rate brokered time deposits resulting from changes in interest rates. Also at December 31, 2015, United had one interest rate swap with a notional 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 nine months ended September 30, 2016, United recognized net gains of $1.51 million and $2.37 million, respectively, related to ineffectiveness in the fair value hedging relationships. The ineffectiveness gains were almost entirely offset by the write-off of unamortized prepaid broker fees that were incurred as part of the original brokered certificates of deposit. The 2016 ineffectiveness gains mostly resulted from called hedging transactions where United was short the call option in the swap and long the call option on the hedged items (brokered certificates of deposit). Since the instruments were called at par, the difference between the carrying amount of the swap (fair value) and the carrying amount of the hedged item (fair value) on the call date created the ineffectiveness gains. During the three and nine months ended September 30, 2015, United recognized net gains of $14,000 and $184,000, respectively, related to ineffectiveness in the fair value hedging relationships. United also recognized net reductions of interest expense of $388,000 and $1.63 million, respectively, for the three and nine months ended September 30, 2016 and net reductions of interest expense of $1.12 million and $3.39 million, respectively, for the three and nine months ended September 30, 2015 related to United’s 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 nine months ended September 30, 2016 of $262,000 and $508,000, respectively, and reductions of interest revenue on securities during the three and nine months ended September 30, 2015 of $142,000 and $361,000, respectively, related to fair value hedges of corporate bonds. The table below presents the effect of derivatives in fair value hedging relationships on the consolidated statement of operations for the periods indicated (in thousands) Location of Gain Amount of Gain (Loss) Amount of Gain (Loss) (Loss) Recognized Recognized in Income Recognized in Income in Income on on Derivative on Hedged Item Derivative 2016 2015 2016 2015 Three Months Ended September 30, Fair value hedges of brokered CD's Interest expense $ (389 ) $ 4,374 $ 1,945 $ (4,247 ) Fair value hedges of corporate bonds Interest revenue 262 (1,365 ) (307 ) 1,252 $ (127 ) $ 3,009 $ 1,638 $ (2,995 ) Nine Months Ended September 30, Fair value hedges of brokered CD's Interest expense $ 2,882 $ 3,599 $ (268 ) $ (3,365 ) Fair value hedges of corporate bonds Interest revenue (2,145 ) (395 ) 1,896 345 $ 737 $ 3,204 $ 1,628 $ (3,020 ) In certain cases, the estate of deceased brokered certificate of deposit holders may put the certificate of deposit back to the issuing bank 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 and such gains and losses are included in the amount of reported ineffectiveness gains or losses. Credit-Risk-Related Contingent Features United manages its credit exposure on derivatives transactions by entering into a bilateral credit support agreement with each 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. As of September 30, 2016, collateral totaling $32.0 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

Disclosure Of Compensation Related Costs, Share-Based Payments [Abstract]
Stock-Based Compensation	Note 10 – 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). As of September 30, 2016, 2.12 million additional awards could be granted under the plan. Through September 30, 2016, 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. The following table shows stock option activity for the first nine months of 2016. Options Shares Weighted- Weighted- Aggregate Outstanding at December 31, 2015 241,493 $ 89.92 Expired (51,606 ) 134.83 Forfeited (4,199 ) 81.21 Outstanding at September 30, 2016 185,688 77.63 2.2 $ 172 Exercisable at September 30, 2016 176,938 80.66 1.9 132 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 nine months ended September 30, 2016 and 2015. Most of United’s outstanding stock options were granted prior to the economic downturn during which time United’s stock price decreased sharply. The lower stock price has rendered most of United’s outstanding options severely out of the money and potentially 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 $23,000 and $28,000, respectively, in compensation expense related to stock options during the nine months ended September 30, 2016 and 2015. 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 nine months of 2016 or 2015. The table below presents restricted stock units activity for the first nine months of 2016. Restricted Stock Unit Awards Shares Weighted- Outstanding at December 31, 2015 712,667 $ 16.44 Granted 225,886 19.42 Vested (223,733 ) 15.70 Cancelled (39,958 ) 17.01 Outstanding at September 30, 2016 674,862 17.65 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. The value of restricted stock unit awards that are expected to vest is amortized into expense over the vesting period. For the nine months ended September 30, 2016 and 2015, compensation expense of $3.16 million and $3.22 million, respectively, was recognized related to restricted stock unit awards. In addition, for the nine months ended September 30, 2016 and 2015, $75,000 and $95,000, respectively, was recognized in other operating expense for restricted stock unit awards granted to members of United’s board of directors. The total intrinsic value of outstanding restricted stock unit awards was $14.2 million at September 30, 2016. As of September 30, 2016, there was $9.39 million of unrecognized compensation cost 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 2.62 years. The aggregate grant date fair value of options and restricted stock unit awards that vested during the nine months ended September 30, 2016 was $3.51 million.

Equity [Abstract]
Common and Preferred Stock Issued / Common Stock Issuable	Note 11 – 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 nine months ended September 30, 2016 and 2015, 2,938 shares and 1,564 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 nine months of 2016 and 2015, United issued 12,906 shares and 10,197 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 September 30, 2016 and December 31, 2015, 520,014 and 458,953 shares of common stock, respectively, were issuable under the deferred compensation plan. In the first quarter of 2016, United redeemed all of its outstanding Series H preferred stock. The preferred stock was redeemed at par and did not result in any gain or loss. In the second quarter of 2016, United amended its articles of incorporation to increase the number of authorized shares of common stock from 100 million to 150 million shares. On March 22, 2016, United announced that its Board of Directors had authorized a new 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 nine months of 2016, United repurchased 764,000 shares under the program. As of September 30, 2016, $36.3 million of United’s outstanding common stock may be repurchased under the program.

Income Tax Disclosure [Abstract]
Income Taxes	Note 12 – Income Taxes The income tax provision for the three and nine months ended September 30, 2016 was $15.8 million and $44.7 million, respectively, which represents an effective tax rate of 37.8% for both periods. The income tax provision for the three and nine months ended September 30, 2015 was $10.9 million and $32.4 million, respectively, which represents an effective tax rate of 37.8% for both periods. At September 30, 2016 and December 31, 2015, United maintained a valuation allowance on its net deferred tax asset of $4.71 million and $4.28 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 September 30, 2016. 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 $4.71 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 September 30, 2016 that it was more likely than not that United’s net deferred tax asset of $156 million will be realized is based upon management’s estimate of future taxable income. Management’s estimate of future taxable income is based on 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 September 30, 2016 and December 31, 2015, unrecognized income tax benefits totaled $3.79 million and $3.98 million, respectively.

Assets and Liabilities Measured

Assets and Liabilities Measured at Fair Value	9 Months Ended
	Sep. 30, 2016
Fair Value [Abstract]
Assets and Liabilities Measured at Fair Value	Note 13 – 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 September 30, 2016, 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 Government Guaranteed Loans United recognizes servicing rights upon the sale of government guaranteed 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. Pension Plan Assets For information on the fair value of pension plan assets, see Note 17 in the Annual Report on Form 10-K for the year ended December 31, 2015.

Interest income on these loans is calculated based on the note rate of the loan and is recorded in interest revenue. During the third quarter of 2016, net gains resulting from changes in fair value of these loans of $11,000 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. 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 assets are not measured at fair value on a recurring basis, but are subject to fair value adjustments in certain circumstances. 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 September 30, 2016 and December 31, 2015, for which a nonrecurring fair value adjustment was recorded during the year-to-date periods presented (in thousands) September 30, 2016 Level 1 Level 2 Level 3 Total Loans $ - $ - $ 7,556 $ 7,556 December 31, 2015 Loans $ - $ - $ 7,589 $ 7,589 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. United’s cash and cash equivalents and repurchase agreements have short maturities and therefore the carrying value approximates fair value. The fair value of securities available-for-sale equals the balance sheet 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. Because no ready market exists for a significant portion of United’s financial instruments, fair value estimates are based on many judgments. These 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 and at variable rates. Therefore, both the carrying amount and the estimated fair value associated with these instruments are 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 September 30, 2016 Amount Level 1 Level 2 Level 3 Total Assets: Securities held to maturity $ 344,917 $ - $ 357,550 $ - $ 357,550 Loans, net 6,662,149 - - 6,620,163 6,620,163 Mortgage loans held for sale 30,535 - 31,596 - 31,596 Residential mortgage servicing rights 3,673 - - 3,694 3,694 Liabilities: Deposits 8,441,599 - 8,447,293 - 8,447,293 Federal Home Loan Bank advances 449,407 - 449,415 - 449,415 Long-term debt 174,959 - - 174,946 174,946 December 31, 2015 Assets: Securities held to maturity $ 364,696 $ - $ 371,658 $ - $ 371,658 Loans, net 5,926,993 - - 5,840,554 5,840,554 Mortgage loans held for sale 24,231 - 24,660 - 24,660 Residential mortgage servicing rights 3,370 - - 3,521 3,521 Liabilities: Deposits 7,873,193 - 7,881,109 - 7,881,109 Federal Home Loan Bank advances 430,125 - 430,119 - 430,119 Long-term debt 163,836 - - 166,668 166,668

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Note 14 – Commitments and Contingencies United is party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit and letters of credit. These instruments involve, to varying degrees, elements of credit risk in excess of the amount recognized in the balance sheet. The contract amounts of these instruments reflect the extent of involvement United has in particular classes of financial instruments. The exposure to credit loss in the event of nonperformance by the other party to the financial instrument for commitments to extend credit and letters of credit written is represented by the contractual amount of these instruments. United uses the same credit policies in making commitments and conditional obligations as it uses for underwriting on-balance sheet instruments. In most cases, collateral or other security is required to support financial instruments with credit risk. The following table summarizes the contractual amount of off-balance sheet instruments as of the dates indicated (in thousands) September 30, December 31, 2016 2015 Financial instruments whose contract amounts represent credit risk: Commitments to extend credit $ 1,418,846 $ 1,351,446 Letters of credit 19,728 23,373 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 September 30, 2016, the Bank had invested $2.51 million in these limited partnerships and had committed to fund an additional $1.99 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.
