UNITED COMMUNITY BANKS, INC. AND SUBSIDIARIES

Notes to Consolidated Financial Statements

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 nine months ended September 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.

Note 2 –Accounting Standards Updates and Recently Adopted Standards

Accounting Standards Updates

In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers.  This ASU provides guidance on the recognition of revenue from contracts with customers.  The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services.  This guidance is effective for public entities for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period, and will be applied retrospectively either to each prior reporting period or with a cumulative effect recognized at the date of initial application. Because the guidance does not apply to revenue associated with financial instruments, including loans and securities, United does not expect the new revenue recognition guidance to have a material impact on the consolidated financial statements. United continues to evaluate the changes in disclosures required by the new guidance.

In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). This update requires a lessee to recognize in the statement of financial position a liability to make lease payments (the lease liability) and a right-of-use asset representing its right to use the underlying asset for the lease term. For leases with a term of 12 months or less, a lessee is permitted to make an accounting policy election not to recognize lease assets and lease liabilities. For public entities, this update is effective for fiscal years beginning after December 15, 2018, with modified retrospective application to prior periods presented. Upon adoption, United expects to report higher assets and liabilities as a result of including leases on the consolidated balance sheet. At December 31, 2016, future minimum lease payments amounted to $29.1 million. United does not expect the new guidance to have a material impact on the consolidated statement of income or the consolidated statement of shareholders’ equity.

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. The new guidance replaces the incurred loss impairment methodology in current GAAP with an expected credit loss methodology and requires consideration of a broader range of information to determine credit loss estimates. Financial assets measured at amortized cost will be presented at the net amount expected to be collected by using an allowance for credit losses. Purchased credit impaired loans will receive an allowance account at the acquisition date that represents a component of the purchase price allocation. Credit losses relating to available-for-sale debt securities will be recorded through an allowance for credit losses, with such allowance limited to the amount by which fair value is below amortized cost. Application of this update will primarily be on a modified retrospective approach, although the guidance for debt securities for which an other-than-temporary impairment has been recognized before the effective date and for loans previously covered by ASC 310-30, Receivables – Loans and Debt Securities Acquired with Deteriorated Credit Quality will be applied on a prospective basis. For public entities, this update is effective for fiscal years beginning after December 15, 2019. Upon adoption, United expects that the allowance for credit losses will be higher given the change to estimated losses for the estimated life of the financial asset, however management is still in the process of determining the magnitude of the increase. Management has formed a steering committee and has begun developing a project plan to ensure it is prepared for implementation by the effective date.

Notes to Consolidated Financial Statements

In March 2017, the FASB issued ASU No. 2017-07, Compensation – Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost. This ASU requires that an employer disaggregate the service cost component from the other components of net benefit cost. The amendments also provide explicit guidance on how to present the service cost component and the other components of net benefit cost and allow only the service cost component to be eligible for capitalization. For public entities, this update is effective for fiscal years beginning after December 15, 2017, with retrospective presentation of the service cost and other components and prospective application for any capitalization of service cost. The adoption of this update is not expected to have a material impact on the consolidated financial statements.

In March 2017, the FASB issued ASU No. 2017-08, Receivables – Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities. This update shortens the amortization period for certain callable debt securities held at a premium. Specifically, the amendments require the premium to be amortized to the earliest call date. For securities held at a discount, the discount will continue to be amortized to maturity. For public entities, this update is effective for fiscal years beginning after December 15, 2018, with modified retrospective application. The adoption of this update is not expected to have a material impact on the consolidated financial statements.

In May 2017, the FASB issued ASU No. 2017-09, Compensation – Stock Compensation (Topic 718): Scope of Modification Accounting. This update clarifies which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting. Specifically, modification accounting should be applied unless the fair value of the modified award is the same as the original award immediately before modification, the vesting conditions of the modified award are the same as the original award immediately before modification, and the classification of the modified award as an equity instrument or a liability instrument is the same as the classification of the original award immediately before modification. For public entities, this update is effective for fiscal years beginning after December 15, 2017, with prospective application. The adoption of this update is not expected to have a material impact on the consolidated financial statements.

In August 2017, The FASB issued ASU No. 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities. This update expands and refines hedge accounting for both nonfinancial and financial risk components and aligns the recognition and presentation of the effects of the hedging instrument and the hedged item in the financial statements. This update also makes certain targeted improvements to simplify the application of hedge accounting guidance and ease the administrative burden of hedge documentation requirements and assessing hedge effectiveness. For public entities, this update is effective for fiscal years beginning after December 15, 2018. For cash flow and net investment hedges existing at the date of adoption, an entity should apply a cumulative-effect adjustment related to eliminating the separate measurement of ineffectiveness to accumulated other comprehensive income with a corresponding adjustment to the opening balance of retained earnings. The amended presentation and disclosure guidance is required prospectively. The adoption of this update is not expected to have a material impact on the consolidated financial statements.

Recently Adopted Standards

In March 2016, the FASB issued ASU No. 2016-09, Compensation – Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. This update simplified several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. United adopted this standard effective January 1, 2017, with no material impact on the consolidated financial statements, although management expects more volatility in the effective tax rate as excess tax benefits and deficiencies on stock compensation transactions flow through income tax expense rather than capital surplus. United prospectively adopted the amendment requiring that excess tax benefits and deficiencies be recognized as income tax expense or benefit in the income statement and as an operating activity in the statement of cash flows. In addition, United elected to account for forfeitures as they occur, rather than estimate the number of awards expected to vest. United retrospectively implemented the clarification that cash paid by an employer when directly withholding shares for tax-withholding purposes should be classified as a financing activity.

Note 3 – Acquisitions

Acquisition of HCSB Financial Corporation

On July 31, 2017, United completed the acquisition of HCSB Financial Corporation (“HCSB”) and its wholly-owned bank subsidiary, Horry County State Bank. HCSB operated eight branches in coastal South Carolina. In connection with the acquisition, United acquired $390 million of assets and assumed $347 million of liabilities. Under the terms of the merger agreement, HCSB shareholders received .0050 shares of United common stock for each share of HCSB common stock issued and outstanding at the closing date. 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 $23.9 million, representing the intangible value of HCSB’s 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 $3.48 million using the sum-of-the-years-digits method over six years, which represents the expected useful life of the asset. United will amortize the related noncompete agreements of $2.24 million using the straight line method over the terms of the agreements, which vary between one year and two years.

United’s operating results for the period ended September 30, 2017 include the operating results of the acquired assets and assumed liabilities for the period subsequent to the acquisition date of July 31, 2017.

The purchased assets and assumed liabilities were recorded at their acquisition date fair values and are summarized in the table below (in thousands).

Unrealized losses at September 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 nine months ended September 30, 2017 or 2016.

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, 2017 and 2016 (in thousands).

At September 30, 2017 and December 31, 2016, loans totaling $3.57 billion and $3.33 billion, respectively, were pledged as collateral to secure Federal Home Loan Bank advances and other contingent funding sources.

At September 30, 2017, the carrying value and outstanding balance of purchased credit impaired (“PCI”) loans accounted for under ASC 310-30 were $68.7 million and $104 million, respectively. At December 31, 2016, the carrying value and outstanding balance of PCI loans were $62.8 million and $87.9 million, respectively. The following table presents changes in the value of the accretable yield for PCI loans for the periods indicated (in thousands):

	Three Months Ended September 30,						Nine Months Ended September 30,
	2017			2016			2017			2016
Balance at beginning of period	$	11,365		$	5,337		$	7,981		$	4,279

Changes in expected cash flows that do not affect nonaccretable difference		735			362			2,505			1,909
Balance at end of period	$	14,598		$	8,151		$	14,598		$	8,151

In addition to the accretable yield on PCI loans, the fair value adjustments on purchased loans outside the scope of ASC 310-30 are also accreted to interest revenue over the life of the loans. At September 30, 2017 and December 31, 2016, the remaining accretable fair value marks on loans acquired through a business combination and not accounted for under ASC 310-30 were $9.19 million and $7.14 million, respectively. In addition, indirect auto loans purchased at a premium outside of a business combination have a remaining premium of $9.19 million and $11.4 million, respectively, as of September 30, 2017 and December 31, 2016. During the three months ended September 30, 2017, United did not purchase indirect auto loans. During the nine months ended September 30, 2017, United purchased indirect auto loans of $81.7 million. During the three and nine months ended September 30, 2016, United purchased indirect auto loans of $38.8 million and $149 million, respectively.

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.

Management individually evaluates for impairment all non-PCI relationships that are on nonaccrual with a balance of $500,000 or greater, all troubled debt restructurings (“TDRs”), and all accruing substandard loans greater than $2 million. 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.

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.

Notes to Consolidated Financial Statements

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.

The following table presents loans individually evaluated for impairment by class of loans as of the dates indicated (in thousands).

As of September 30, 2017 and December 31, 2016, $2.98 million and $2.90 million, respectively, of specific reserves were allocated to customers whose loan terms have been modified in TDRs. United committed to lend additional amounts totaling up to $45,000 and $95,000, respectively, at September 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 nine months ended September 30, 2017 and 2016 are presented in the table below. In addition, the following table presents loans modified under the terms of a TDR that defaulted (became 90 days or more delinquent) during the periods presented and were initially restructured within one year prior to default (dollars in thousands).

Nonaccrual loans include both homogeneous loans that are collectively evaluated for impairment and individually evaluated impaired loans, based on the size of the loan. 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 September 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 $291,000 and $262,000 for the three months ended September 30, 2017 and 2016, respectively, and $814,000 and $686,000 for the nine months ended September 30, 2017 and 2016, respectively.

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. Loans in this category are presently protected from apparent loss; however, weaknesses exist that could cause future impairment, including the deterioration of financial ratios, past due status and questionable management capabilities. These loans require more than the ordinary amount of supervision. Collateral values generally afford adequate coverage, but may not be immediately marketable.

Substandard. These loans are inadequately protected by the current net worth and paying capacity of the obligor or by the collateral pledged. Specific and well-defined weaknesses exist that may include poor liquidity and deterioration of financial ratios. The loan may be past due and related deposit accounts experiencing overdrafts. There is the distinct possibility that United will sustain some loss if deficiencies are not corrected. If possible, immediate corrective action is taken.

23

UNITED COMMUNITY BANKS, INC. AND SUBSIDIARIES

Notes to Consolidated Financial Statements

Doubtful. Specific weaknesses characterized as Substandard that are severe enough to make collection in full highly questionable and improbable. There is no reliable secondary source of full repayment.

Loss. Loans categorized as Loss have the same characteristics as Doubtful; however, probability of loss is certain. Loans classified as Loss are charged off.

Consumer Purpose Loans. United applies a pass / fail grading system to all consumer purpose loans. Under the pass / fail grading system, consumer purpose loans that become past due 90 days or are in bankruptcy are classified as “fail” and all other loans are classified as “pass”. For reporting purposes, consumer purpose loans classified as “fail” are reported in the substandard column and all other consumer purpose loans are reported in the “pass” column.

Loans not meeting the criteria above that are analyzed individually as part of the above described process are considered to be pass rated loans.

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 in 2017 or the third 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					Nine Months Ended

At September 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; 60,489 shares of common stock issuable upon exercise of stock options granted to employees with a weighted average exercise price of $24.15; and 710,145 shares of common stock issuable upon the vesting of restricted stock unit awards.

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 the vesting of restricted stock unit awards.

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 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.

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.

Notes to Consolidated Financial Statements

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 September 30, 2017 and December 31, 2016 United did not have any designated 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 $545,000 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).

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, 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 September 30, 2017, United had one interest rate swap with a notional value of $30.0 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 nine months ended September 30, 2017, United recognized net losses of $160,000 and $612,000, respectively, related to ineffectiveness in the fair value hedging relationships. 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. United also recognized net reductions of interest expense of $40,000 and $137,000, respectively, for the three and nine months ended September 30, 2017 and net reductions of interest expense of $388,000 and $1.63 million, respectively, for the three and nine months ended September 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 nine months ended September 30, 2017 of $71,000 and $244,000, respectively, and reductions of interest revenue on securities during the three and nine months ended September 30, 2016 of $262,000 and $508,000, respectively, related to fair value hedges of corporate bonds.

In certain cases, the estate of deceased brokered certificate of deposit holders may put the certificate of deposit back to United at par upon the death of the holder. When these estate puts occur, a gain or loss is recognized for the difference between the fair value and the par amount of the deposits put back. The change in the fair value of brokered time deposits that are being hedged in fair value hedging relationships reported in the table above includes gains and losses from estate puts 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, 2017, collateral totaling $20.9 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.

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). Through September 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 September 30, 2017, 1.94 million additional shares remained available for grant under the plan.

The following table shows stock option activity for the first nine months of 2017.

Options	Shares			Weighted- Average Exercise Price		Weighted- Average Remaining Contractual Term (Years)		Aggregate Intrinisic Value ($000)
Outstanding at December 31, 2016		72,665		$	34.34
Expired		(1,538	)		147.60
Cancelled		(10,638	)		75.91
Outstanding at September 30, 2017		60,489			24.15		3.3	$	365
Exercisable at September 30, 2017		55,489			24.82		3.0		306

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, 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 $22,000 and $23,000, respectively, in compensation expense related to stock options during the nine months ended September 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 nine months of 2017 or 2016.

The table below presents restricted stock units activity for the first nine months of 2017.

Restricted Stock Unit Awards	Shares			Weighted- Average Grant- Date Fair Value		Weighted- Average Remaining Contractual Term (Years)		Aggregate Intrinisic Value ($000)
Outstanding at December 31, 2016		690,970		$	18.60
Granted		259,220			26.48
Vested		(230,080	)		17.09			$	6,326
Cancelled		(9,965	)		19.99

UNITED COMMUNITY BANKS, INC. AND SUBSIDIARIES

Notes to Consolidated Financial Statements

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 nine months ended September 30, 2017 and 2016, expense of $4.13 million and $3.16 million, respectively, was recognized related to employee restricted stock unit awards. Of the expense recognized related to restricted stock unit awards during the nine months ended September 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 $3.43 million was recognized in compensation expense. In addition, for the nine months ended September 30, 2017 and 2016, $212,000 and $75,000, respectively, was recognized in other operating expense for restricted stock unit awards granted to members of United’s board of directors.

As of September 30, 2017, there was $12.4 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 3.14 years.

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, 2017 and 2016, 2,842 shares and 2,938 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 2017 and 2016, United issued 10,265 shares and 12,906 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, 2017 and December 31, 2016, 588,445 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 nine months of 2017, United did not repurchase any shares under the program. As of September 30, 2017, $36.3 million of United’s outstanding common stock may be repurchased under the program. In November of 2017, the Board of Directors extended this program through December 31, 2018.

Note 12 – Income Taxes

The income tax provision for the three and nine months ended September 30, 2017 was $15.7 million and $50.7 million, respectively, which represents effective tax rates of 36.0% and 38.9%, respectively, for each period. 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. 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 nine months of 2016.

At September 30, 2017 and December 31, 2016, United maintained a valuation allowance on its net deferred tax asset of $4.20 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 September 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 $4.20 million is related to specific state income tax credits that have short carryforward periods and are expected to expire unused.

32

UNITED COMMUNITY BANKS, INC. AND SUBSIDIARIES

Notes to Consolidated Financial Statements

The valuation allowance could fluctuate in future periods based on the assessment of the positive and negative evidence. Management's conclusion at September 30, 2017 that it was more likely than not that the net deferred tax asset of $129 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 2014. 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, 2017 and December 31, 2016, unrecognized income tax benefits totaled $3.87 million and $3.89 million, respectively.

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

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

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

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

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

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, impaired loans where an allowance is established based on the fair value of collateral require classification in the fair value hierarchy. When the fair value of the collateral is based on an observable market price or a current appraised value, United records the impaired loan as nonrecurring Level 2. When an appraised value is not available or management determines the fair value of the collateral is further impaired below the appraised value and there is no observable market price, United records the impaired loan as nonrecurring Level 3.

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, 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.

Fair Value Option

At September 30, 2017, mortgage loans held for sale for which the fair value option was elected had an aggregate fair value and outstanding principal balance of $30.1 million and $29.1 million, respectively. 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 nine months ended September 30, 2017, net gains resulting from changes in fair value of these loans of $264,000 and $708,000, 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 nine months ended September 30, 2016, net gains resulting from changes in fair value of these loans of $11,000 were recorded in mortgage loan and other related fees.

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 September 30, 2017 and December 31, 2016, for which a nonrecurring fair value adjustment was recorded during the year-to-date periods presented (in thousands).

	Level 1		Level 2		Level 3		Total
September 30, 2017
Loans	$	-	$	-	$	8,843	$	8,843
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.

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 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).

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, 2017, the Bank had invested $4.13 million in these limited partnerships and had committed to fund an additional $5.37 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.

Note 16 – Subsequent Events

On October 15, 2017, United paid off $35 million of maturing long-term debt that had an interest rate of 9%. On November 3, 2017, United's Board of Directors approved a regular quarterly cash dividend of ten cents per common share. The dividend is payable January 5, 2018, to shareholders of record on December 15, 2017.

Four Oaks Fincorp, Inc.

On November 1, 2017, United completed its previously announced acquisition of Four Oaks Fincorp, Inc. (“FOFN”) and its wholly-owned bank subsidiary, Four Oaks Bank & Trust Company. As of June 30, 2017, FOFN had total assets of $740 million, loans of $498 million and deposits of $560 million. Four Oaks Bank & Trust Company, which operated 14 banking offices in the Raleigh, North Carolina metropolitan statistical area, will operate under the Four Oaks Bank & Trust Company brand until the system conversions are completed in the second quarter of 2018, at which time it will begin to operate as United Community Bank.

Under the terms of the merger agreement, FOFN shareholders received .6178 shares of United common stock and $1.90 for each share of FOFN common stock, or an aggregate of approximately $128 million based on United’s closing price of $27.42 on October 31, 2017.

The acquisition will be accounted for as a business combination, subject to the provisions of ASC 805-10-50, Business Combinations. 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.

Overview

The following discussion is intended to provide insight into the results of operations and financial condition of United Community Banks, Inc. (“United”) and its subsidiaries and should be read in conjunction with the consolidated financial statements and accompanying notes.

United is a bank holding company registered with the Board of Governors of the Federal Reserve under the Bank Holding Company Act of 1956 that was incorporated under the laws of the State of Georgia in 1987 and commenced operations in 1988. At September 30, 2017, United had total consolidated assets of $11.1 billion, total loans of $7.20 billion, total deposits of $9.13 billion, and shareholders’ equity of $1.22 billion.

United conducts substantially all of its operations through its wholly-owned Georgia bank subsidiary, United Community Bank (the “Bank”), which as of September 30, 2017, operated at 142 locations throughout the Atlanta-Sandy Springs-Roswell, Georgia, and Gainesville, Georgia metropolitan statistical areas, upstate and coastal South Carolina, north and coastal Georgia, western North Carolina, and east Tennessee, as well as a commercial loan office in Charlotte, North Carolina.

On July 1, 2016, United completed its previously announced acquisition of Tidelands Bancshares, Inc. (“Tidelands”) and its wholly-owned bank subsidiary, Tidelands Bank.  Tidelands’ results are included in United’s consolidated results beginning on the acquisition date.

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.  HCSB’s results are included in United’s consolidated results beginning on the acquisition date.

United reported net income of $27.9 million, or $.38 per diluted share, for the third quarter of 2017, compared to net income of $25.9 million, or $.36 per diluted share, for the third quarter of 2016. For the nine months ended September 30, 2017, United reported net income of $79.7 million, or $1.10 per diluted share, compared to $73.4 million, or $1.02 per diluted share, for the first nine months of 2016. The increase in earnings per share resulted from an increase in net interest revenue, partially offset by a decrease in fee revenue and an increase in operating expenses.

Net interest revenue increased to $89.8 million for the third quarter of 2017, compared to $79.0 million for the third quarter of 2016, primarily due to higher loan volume, much of which resulted from the acquisition of HCSB. Net interest margin increased to 3.54% for the three months ended September 30, 2017 from 3.34% for the same period in 2016 mostly due to the effect of rising interest rates on floating rate loans and investment securities. Growth in the loan portfolio also led to a more favorable earning asset mix. For the nine months ended September 30, 2017, net interest revenue was $258 million and the net interest margin was 3.49% compared to net interest revenue of $229 million and net interest margin of 3.36% for the same period in 2016.

The provision for credit losses was $1.00 million for the third quarter of 2017, compared to a release of provision of $300,000 for the third quarter of 2016. For the nine months ended September 30, 2017, the provision for credit losses was $2.60 million, compared to a release of provision of $800,000 for the same period in 2016. Net charge-offs for the third quarter of 2017 were $1.64 million, compared to $1.36 million for the third quarter of 2016.

As of September 30, 2017, the allowance for loan losses was $58.6 million, or .81% of loans, compared to $61.4 million, or .89% of loans, at December 31, 2016 reflecting continued asset quality improvement and the effect of loans acquired through a business combination which are recorded at fair value with credit losses reflected in the value rather than in the allowance for loan losses. Nonperforming assets of $25.7 million were .23% of total assets at September 30, 2017, down from .28% at December 31, 2016 primarily due to sales of foreclosed properties. During the third quarter of 2017, $7.96 million in loans were placed on nonaccrual compared with $6.68 million in the third quarter of 2016.

Fee revenue of $20.6 million for the third quarter of 2017 was down $5.79, or 22%, from the third quarter of 2016. Service charges and fees decreased 24% compared to third quarter of 2016 due to the effect of the Durbin Amendment of the Dodd-Frank Act, which took effect for United in the third quarter of 2017 and limited the amount of interchange fees United could earn on debit card transactions. For the first nine months of 2017, fee revenue of $66.3 million decreased $2.13 million, or 3%, from the same period in 2016, primarily due to the same factors that affected the quarterly results.

For the third quarter and first nine months of 2017, operating expenses of $65.7 million and $192 million, respectively, were up $1.65 million and $11.8 million from the same periods of 2016, primarily due to the addition of HCSB and (for the year to date period) Tidelands operating expenses since acquisition. Salaries and benefits expense increased $1.55 million from third quarter 2016 and $8.94 million from the first nine months of 2016, also due to the addition of HCSB and Tidelands and higher incentives and commissions in connection with increased lending activities and improvement in earnings performance.

Recent Developments

On November 1, 2017, United completed its previously announced acquisition of Four Oaks Fincorp, Inc. (“FOFN”) and its wholly-owned bank subsidiary, Four Oaks Bank & Trust Company. As of June 30, 2017, FOFN had total assets of $740 million, loans of $498 million and deposits of $560 million. Four Oaks Bank & Trust Company, which operated 14 banking offices in the Raleigh, North Carolina metropolitan statistical area, will operate under the Four Oaks Bank & Trust Company brand until the system conversions are completed in the second quarter of 2018, at which time it will begin to operate as United Community Bank.

Under the terms of the merger agreement, FOFN shareholders received .6178 shares of United common stock and $1.90 for each share of FOFN common stock, or an aggregate of approximately $128 million based on United’s closing price of $27.42 on October 31, 2017.

Critical Accounting Policies

The accounting and reporting policies of United are in accordance with accounting principles generally accepted in the United States (“GAAP”) and conform to general practices within the banking industry. The more critical accounting and reporting policies include United’s accounting for the allowance for loan losses, fair value measurements, and income taxes which involve the use of estimates and require significant judgments to be made by management. Different assumptions in the application of these policies could result in material changes in United’s consolidated financial position or consolidated results of operations. See “Asset Quality and Risk Elements” herein for additional discussion of United’s accounting methodologies related to the allowance for loan losses.

GAAP Reconciliation and Explanation

This Form 10-Q contains financial information determined by methods other than in accordance with GAAP. Such non-GAAP financial information includes the following measures: “tangible book value per common share,” “average tangible equity to average assets,” “tangible equity to assets,” “average tangible common equity to average assets,” “tangible common equity to assets” and “tangible common equity to risk-weighted assets.” In addition, management presents non-GAAP operating performance measures, which exclude merger-related and other items that are not part of United’s ongoing business operations. Operating performance measures include “expenses – operating,” “net income – operating,” “net income available to common shareholders – operating,” “diluted net income per common share – operating,” “return on common equity – operating,” “return on tangible common equity – operating,” “return on assets – operating,” “dividend payout ratio – operating” and “efficiency ratio – operating.” Management has developed internal processes and procedures to capture and account for merger-related and other charges and those charges are reviewed with the audit committee of United’s Board of Directors each quarter. Management uses these non-GAAP measures because it believes they may provide useful supplemental information for evaluating United’s operations and performance over periods of time, as well as in managing and evaluating United’s business and in discussions about United’s operations and performance. Management believes these non-GAAP measures may also provide users of United’s financial information with a meaningful measure for assessing United’s financial results and credit trends, as well as a comparison to financial results for prior periods. These non-GAAP measures should be viewed in addition to, and not as an alternative to or substitute for, measures determined in accordance with GAAP and are not necessarily comparable to other similarly titled measures used by other companies. To the extent applicable, reconciliations of these non-GAAP measures to the most directly comparable measures as reported in accordance with GAAP are included in the table on page 45.

Results of Operations

United reported net income of $27.9 million for the third quarter of 2017. This compared to net income of $25.9 million for the same period in 2016. For the third quarter of 2017, diluted earnings per common share were $.38 compared to $.36 for the third quarter of 2016. For the nine months ended September 30, 2017, United reported net income of $79.7 million compared to net income of $73.4 million for the same period in 2016.

United reported operating net income of $30.2 million and $87.9 million, respectively, for the third quarter and first nine months of 2017, compared to $27.8 million and $77.8 million, respectively, for the same periods in 2016. For the third quarter of 2017, operating net income excludes merger-related charges and impairment charges on surplus bank properties, which, net of the associated income tax benefit, totaled $2.27 million. For the first nine months of 2017, operating net income excludes merger-related charges, impairment charges on surplus bank properties, executive retirement charges and the release from accumulated other comprehensive income of the disproportionate tax effect related to cash flow hedges, which, net of tax, totaled $8.12 million. For the third quarter and first nine months of 2016, operating net income excludes merger-related charges, which, net of tax, totaled $1.96 million and $4.34 million, respectively.

Net Interest Revenue

Net interest revenue (the difference between the interest earned on assets and the interest paid on deposits and borrowed funds) is the single largest component of total revenue. Management seeks to optimize this revenue while balancing interest rate, credit and liquidity risks. Net interest revenue for the third quarter of 2017 was $89.8 million. Taxable equivalent net interest revenue for the third quarter of 2017 was $90.4 million, which represents an increase of $11.2 million from the same period in 2016. The combination of the larger earning asset base from the acquisition of HCSB and growth in the loan portfolio were responsible for the increase in net interest revenue.

Average loans increased $474 million, or 7%, from the third quarter of last year, while the yield on loans increased 32 basis points, reflecting the effect of rising interest rates on the floating rate loans in the portfolio.

Average interest-earning assets for the third quarter of 2017 increased $689 million, or 7%, from the third quarter of 2016, which was due primarily to the increase in loans, including the acquisition of HCSB loans. Average investment securities for the third quarter of 2017 increased $190 million from a year ago, partially due to the HCSB acquisition. The average yield on the taxable investment portfolio increased 19 basis points from a year ago, primarily due to the impact of higher short-term interest rates on the floating rate portion of the securities portfolio as well as accelerated discount accretion on called asset-backed securities and a higher reinvestment rate on maturing fixed rate investments.

Average interest-bearing liabilities of $6.82 billion for the third quarter of 2017 increased $196 million from the third quarter of 2016. Average non-interest-bearing deposits increased $347 million from the third quarter of 2016 to $2.84 billion for the third quarter of 2017. The average cost of interest-bearing liabilities for the third quarter of 2017 was .53% compared to .39% for the same period in 2016, reflecting higher average rates on money market deposits, NOW deposits, time deposits and brokered time deposits.

The banking industry uses two ratios to measure relative profitability of net interest revenue. The net interest spread measures the difference between the average yield on interest-earning assets and the average rate paid on interest-bearing liabilities. The net interest spread eliminates the effect of non-interest-bearing deposits and gives a direct perspective on the effect of market interest rate movements. The net interest margin is an indication of the profitability of a company’s balance sheet, and is defined as net interest revenue as a percent of average total interest-earning assets, which includes the positive effect of funding a portion of interest-earning assets with non-interest-bearing deposits and stockholders’ equity.

For the third quarters of 2017 and 2016, the net interest spread was 3.37% and 3.22%, while the net interest margin was 3.54% and 3.34%, respectively. The increase in the net interest margin reflects the impact of higher short-term interest rates on floating-rate loans and securities, which exceeded the increase in deposit and other funds pricing from the prior year.

For the first nine months of 2017, net interest revenue was $258 million, an increase of $29.6 million, or 13%, from the first nine months of 2016. Similarly, fully taxable equivalent net interest revenue for the first nine months of 2017 was $260 million, an increase of $30.2 million, or 13%, from the first nine months of 2016. Average earning assets increased 9% to $9.97 billion during the first nine months of 2017 compared to the same period a year ago, primarily due to the increase in loans, including the acquisition of HCSB and Tidelands loans. The yield on earning assets increased 18 basis points to 3.81% in the first nine months of 2017 primarily due to higher loan and securities yields. The higher loan portfolio yield reflects the effect of rising interest rates on the floating rate loans in the portfolio. Investment yield increased 16 basis points for the first nine months of 2017 compared to the same period in 2016, which further improved the net interest margin. The rate on interest-bearing liabilities over the same period increased 10 basis points. The higher yield on interest-earning assets more than offset the higher cost of interest-bearing liabilities and resulted in a 13 basis point increase in the net interest margin from the first nine months of 2016 to the first nine months of 2017.

Provision for Credit Losses

The provision for credit losses is based on management’s evaluation of probable incurred losses in the loan portfolio and corresponding analysis of the allowance for credit losses at quarter-end. Provision for credit losses was $1.00 million for the third quarter of 2017, compared to a release of provision of $300,000 in the third quarter of 2016. The provision for credit losses for the nine months ended September 30, 2017 and 2016 was provision expense of $2.60 million and a release of provision expense of $800,000, respectively. The amount of provision recorded in each period was the amount required such that the total allowance for loan losses reflected the appropriate balance, in the estimation of management, sufficient to cover incurred losses in the loan portfolio. For the three months ended September 30, 2017, net loan charge-offs as an annualized percentage of average outstanding loans were .09% compared to .08% for the same period in 2016.

The allowance for unfunded commitments represents probable incurred losses on unfunded loan commitments that are expected to result in outstanding loan balances. The allowance for unfunded loan commitments was established through the provision for credit losses.

Additional discussion on credit quality and the allowance for loan losses is included in the “Asset Quality and Risk Elements” section of this report on page 54.

Fee Revenue

Fee revenue for the three and nine months ended September 30, 2017 was $20.6 million and $66.3 million, respectively, a decrease of $5.79 million, or 22%, compared to the third quarter of 2016 and a decrease of $2.13 million, or 3%, compared to the first nine months of 2016. The following table presents the components of fee revenue for the periods indicated.

Service charges and fees of $8.22 million and $29.5 million for the third quarter and first nine months of 2017 were down $2.60 million, or 24%, from the third quarter of 2016 and $1.94 million, or 6%, from the first nine months of 2016. The decrease in both periods was primarily due to the impact of the Durbin Amendment to the Dodd Frank Act which became effective for United on July 1, 2017 and reduced United’s debit card interchange fees in the third quarter of 2017 by approximately $2.7 million compared to the second quarter of 2017 and $2.47 million compared to the third quarter of 2016.

Mortgage loan and related fees for the third quarter and first nine months of 2017 were down $1.84 million, or 30%, and $341,000, or 2%, respectively, from the same periods in 2016. The decrease reflects the impact of moving to mandatory delivery of loans to the secondary market from best efforts in late 2016, which accelerated revenue recognition to the time of the rate lock. Also, in the third quarter of 2017, the fair value mark on the mortgage servicing asset was a decrease in value of $419,000. United elected to carry its mortgage servicing asset at fair value effective January 1, 2017. In the third quarter of 2017, United closed 848 loans totaling $193 million compared with 904 loans totaling $194 million in the third quarter of 2016. Year-to-date mortgage production in 2017 amounted to 2,433 loans totaling $548 million, compared to 2,407 loans totaling $522 million for the same period in 2016. United had $117 million and $351 million, respectively, in home purchase mortgage originations in the third quarter and first nine months of 2017, compared with $99.7 million and $292 million, respectively, for the same periods a year ago. The volume of home purchase mortgages relative to total mortgages (both purchases and refinances) in the third quarter of 2017 was 60% compared with 51% in the third quarter of 2016.

Brokerage fees in the third quarter of 2017 decreased 16% compared to the same period of 2016, primarily due to the United States Department of Labor’s new fiduciary rules, effective in June 2017, which implemented a level compensation requirement throughout the industry. Brokerage fees in the first nine months of 2017 increased 6% compared to the same period in 2016, reflecting the addition of several new financial advisors since early 2016.

In the third quarter and first nine months of 2017, United realized $2.81 million and $7.39 million, respectively, in gains from the sales of the guaranteed portion of SBA/USDA loans, compared to $2.48 million and $6.52 million, respectively, in the same periods of 2016. United’s SBA/USDA lending strategy includes selling a portion of the loan production each quarter. United retains the servicing rights on the sold loans and earns a fee for servicing the loans. In the third quarter and first nine months of 2017, United sold the guaranteed portion of loans in the amount of $29.9 million and $83.6 million, respectively, compared to $32.2 million and $78.6 million, respectively, for the same periods a year ago.

Customer derivative fees were down $892,000 and $1.48 million from the third quarter and first nine months of 2016 due to lower demand for this product in the current rate environment.

Other fee revenue was down $522,000, or 13%, for the third quarter of 2017 due to a number of small gains on disposition of assets in 2016. For the first nine months of 2017, other fee revenue was up $1.28 million, or 14%, primarily due to volume driven increases in earnings on bank owned life insurance, increases in miscellaneous banking fees, decreases in losses attributable to hedge ineffectiveness, and increases in the value of equity investments held by United.

Operating expenses for the third quarter of 2017 totaled $65.7 million, up $1.65 million, or 3%, from the third quarter of 2016, primarily due to the inclusion of operating expenses of HCSB. For the nine months ended September 30, 2017, operating expenses totaled $192 million, an increase of $11.8 million, or 7%, from the same period in 2016. The increase year over year reflects the inclusion of the operating expenses of both the Tidelands and the HCSB acquisitions.

Salaries and employee benefits for the third quarter of 2017 were $38.0 million, up $1.55 million, or 4%, from the third quarter of 2016. The increase was due to a number of factors including additional staff resulting from the HCSB acquisition and higher incentives and commissions. For the first nine months of 2017, salaries and employee benefits of $112 million were up $8.94 million, or 9%, from the same period in 2016. Full time equivalent headcount totaled 2,020 at September 30, 2017, up from 1,939 at September 30, 2016, reflecting the addition of HCSB personnel.

Communications and equipment and occupancy expenses decreased in third quarter 2017 relative to the same period in 2016 primarily due to lower telephone charges and service contract charges and lower building maintenance and rental charges. For the first nine months of 2017, communications and equipment and occupancy expenses increased primarily due to the Tidelands acquisition.

Professional fees for the third quarter and first nine months of 2017 were down 6% and 7%, respectively, from the same periods in 2016 due primarily to lower fees related to outsourcing functions.

Amortization of intangibles in the third quarter and first nine months of 2017 decreased from the same periods in 2016 due to the accelerated method used to amortize core deposit intangibles, which more than offset the additional amortization resulting from the HCSB acquisition.

In the third quarter of 2017, merger-related and other charges of $3.18 million consisted of merger costs of $2.04 million and impairment charges on surplus properties of $1.14 million. In the first nine months of 2017, merger-related and other charges of $7.06 million included these costs as well as executive retirement costs, severance, branch closure costs and technology equipment write offs. In the third quarter and first nine months of 2016, merger-related charges of $3.15 million and $6.98 million, respectively, consisted primarily of severance, conversion costs, and legal and professional fees.

Other expense of $6.23 million for the third quarter of 2017 increased $115,000, or 2%, from the third quarter of 2016. Year-to-date, other expenses of $19.7 million increased $1.70 million, or 9%, from the first nine months of 2016. The increase was primarily due to writedowns on foreclosed property and higher lending support costs resulting from higher production volume in the Commercial Banking areas.

Income Taxes

The income tax provision for the three and nine months ended September 30, 2017 was $15.7 million and $50.7 million, respectively, as compared with $15.8 million and $44.7 million, respectively, for the same periods in 2016. The income tax provision represents effective tax rates of 36.0% and 38.9%, respectively, for the third quarter and first nine months of 2017, compared to 37.8% for both periods of 2016. 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 nine months of 2016.

51

At September 30, 2017 and December 31, 2016, United maintained a valuation allowance on its net deferred tax asset of $4.20 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 September 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 $4.20 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, 2017 that it was more likely than not that the net deferred tax asset of $129 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, 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 2014. 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.

Additional information regarding income taxes, including a reconciliation of the differences between the recorded income tax provision and the amount of income tax computed by applying the statutory federal income tax rate to income before income taxes, can be found in Note 17 to the consolidated financial statements filed with United’s Annual Report on Form 10-K for the year ended December 31, 2016.

Balance Sheet Review

Total assets at September 30, 2017 and December 31, 2016 were $11.1 billion and $10.7 billion, respectively. Average total assets for the third quarter and first nine months of 2017 were $11.0 billion and $10.8 billion, respectively, up from $10.3 billion and $9.91 billion, respectively, in the third quarter and first nine months of 2016.

Substantially all of United’s loans are to customers located in the immediate market areas of its community banks in Georgia, North Carolina, South Carolina and Tennessee, including customers who have a seasonal residence in United’s market areas, or are generated by United’s Commercial Banking Solutions division (formerly referred to as Specialized Lending) that focuses on specific commercial loan businesses, such as SBA and franchise lending. More than 77% of the loans were secured by real estate. Total loans averaged $7.15 billion in the third quarter of 2017, compared with $6.68 billion in the third quarter of 2016, an increase of 7% which includes the acquisition of HCSB. At September 30, 2017, total loans were $7.20 billion, an increase of $282 million from December 31, 2016.

53

United’s home equity lines generally require the payment of interest only for a set period after origination. After this initial period, the outstanding balance begins amortizing and requires the payment of both principal and interest. At September 30, 2017 and December 31, 2016, the funded portion of home equity lines totaled $689 million and $655 million, respectively. Approximately 3% of the home equity lines at September 30, 2017 were amortizing. Of the $689 million in balances outstanding at September 30, 2017, $403 million, or 58%, were secured by first liens. At September 30, 2017, 55% of the total available home equity lines were drawn upon.

United monitors the performance of its home equity loans and lines secured by second liens similar to other consumer loans and utilizes assumptions specific to these loans in determining the necessary allowance. United also receives notification when the first lien holder is in the process of foreclosure and upon that notification, management reviews current valuations to determine if any charge-offs are warranted and whether it is in United’s best interest to pay off the first lien holder, in order to potentially limit losses on the second lien.

Asset Quality and Risk Elements

United manages asset quality and controls credit risk through review and oversight of the loan portfolio as well as adherence to policies designed to promote sound underwriting and loan monitoring practices. United’s credit administration function is responsible for monitoring asset quality and Board of Directors approved portfolio limits, establishing credit policies and procedures and enforcing the consistent application of these policies and procedures among all lending units. Additional information on the credit administration function is included in Item 1 under the heading Loan Review and Nonperforming Assets in United’s Annual Report on Form 10-K for the year ended December 31, 2016.

United classifies commercial performing loans as “substandard” when there is a well-defined weakness or weaknesses that jeopardizes the repayment by the borrower and there is a distinct possibility that United could sustain some loss if the deficiency is not corrected. United classifies consumer performing loans as “fail” when the loan is in bankruptcy or voluntary repossession.

The table below presents performing classified loans for the last five quarters.

At September 30, 2017, performing classified loans totaled $100 million and increased $8.74 million from the prior quarter-end, and decreased $21.1 million from a year ago. Performing classified loans reflect a general downward trend, offset by acquisition activity. The increase in performing classified loans in South Carolina in the third quarter of 2017 was attributable to the HCSB acquisition.

Reviews of classified performing and non-performing loans, past due loans and larger credits are conducted on a regular basis and are designed to identify risk migration and potential charges to the allowance for loan losses. These reviews are presented by the responsible lending officers or respective credit officer and specific action plans are discussed along with the financial strength of borrowers, the value of the applicable collateral, past loan loss experience, anticipated loan losses, changes in risk profile, the effect of prevailing economic conditions on the borrower and other factors specific to the borrower and its industry. In addition to the reviews mentioned above, United also has an internal loan review team which directly reviews the portfolio in conjunction with external loan review to ensure the objectivity of the loan review process.

The provision for credit losses charged to earnings is based upon management’s judgment of the amount necessary to maintain the allowance at a level appropriate to absorb probable incurred losses in the loan portfolio at the balance sheet date. The amount each quarter is dependent upon many factors, including growth and changes in the composition of the loan portfolio, net charge-offs, delinquencies, management’s assessment of loan portfolio quality, the value of collateral, and other macro-economic factors and trends. The evaluation of these factors is performed quarterly by management through an analysis of the appropriateness of the allowance for loan losses.

The allowance for credit losses, which includes a portion related to unfunded commitments, totaled $61.1 million at September 30, 2017, compared with $63.4 million at December 31, 2016. At September 30, 2017, the allowance for loan losses was $58.6 million, or .81% of loans, compared with $61.4 million, or .89% of total loans, at December 31, 2016.

Management believes that the allowance for credit losses at September 30, 2017 reflects the probable incurred losses in the loan portfolio and unfunded loan commitments. This assessment involves uncertainty and judgment and is subject to change in future periods. The amount of any changes could be significant if management’s assessment of loan quality or collateral values change substantially with respect to one or more loan relationships or portfolios. In addition, bank regulatory authorities, as part of their periodic examination of the Bank, may require adjustments to the provision for credit losses in future periods if, in their opinion, the results of their review warrant such additions. See the “Critical Accounting Policies” section for additional information on the allowance for loan losses.

Nonperforming Assets

The table below summarizes nonperforming assets.

Nonperforming assets as a percentage of total loans and OREO		.36			.43
Nonperforming assets as a percentage of total assets		.23			.28

At September 30, 2017, nonperforming loans were $22.9 million compared to $21.5 million at December 31, 2016. Nonperforming assets, which include nonperforming loans and foreclosed real estate, totaled $25.7 million at September 30, 2017 and $29.5 million at December 31, 2016.

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. 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.

Purchased credit impaired (“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 as 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, 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 following table summarizes nonperforming assets by category and market as of the dates indicated.

Foreclosed property is initially recorded at fair value, less estimated costs to sell. If the fair value, less estimated costs to sell at the time of foreclosure is less than the loan balance, the deficiency is charged against the allowance for loan losses. If the lesser of fair value, less estimated costs to sell or the listed selling price, less the costs to sell, of the foreclosed property decreases during the holding period, a valuation allowance is established with a charge to foreclosed property expense. When the foreclosed property is sold, a gain or loss is recognized on the sale for the difference between the sales proceeds and the carrying amount of the property. Financed sales of foreclosed property are accounted for in accordance with ASC 360-20, Real Estate Sales.

Impaired Loans

At September 30, 2017 and December 31, 2016, United had $65.2 million and $73.2 million, respectively, in loans with terms that have been modified in TDRs. Included therein were $5.65 million and $5.35 million, respectively, of TDRs that were classified as nonaccrual and were included in nonperforming loans. The remaining TDRs with an aggregate balance of $59.6 million and $67.8 million, respectively, were performing according to their modified terms and are therefore not considered to be nonperforming assets.

At September 30, 2017 and December 31, 2016, there were $83.6 million and $85.7 million, respectively, of loans classified as impaired under the definition outlined in the Accounting Standards Codification, including TDRs which are by definition considered impaired. Included in impaired loans at September 30, 2017 and December 31, 2016 was $29.2 million and $28.3 million, respectively, that did not require specific reserves or had previously been charged down to net realizable value. The balance of impaired loans at September 30, 2017 and December 31, 2016 of $54.4 million and $57.4 million, respectively, had specific reserves that totaled $4.44 million and $3.45 million, respectively. The average recorded investment in impaired loans for the third quarters of 2017 and 2016 was $84.2 million and $93.0 million, respectively. For the nine months ended September 30, 2017 and 2016, the average recorded investment in impaired loans was $84.2 million and $92.0 million, respectively. For the three and nine months ended September 30, 2017, United recognized $931,000 and $2.89 million in interest revenue on impaired loans compared to $1.13 million and $3.26 million, respectively, for the same periods of the prior year.

 Investment Securities

The composition of the investment securities portfolio reflects United’s investment strategy of maintaining an appropriate level of liquidity while providing a relatively stable source of revenue. The investment securities portfolio also provides a balance to interest rate risk and credit risk in other categories of the balance sheet while providing a vehicle for the investment of available funds, furnishing liquidity, and supplying securities to pledge as required collateral for certain deposits and borrowings, including repurchase agreements.

At September 30, 2017 and December 31, 2016, United had securities held-to-maturity with a carrying amount of $307 million and $330 million, respectively, and securities available-for-sale totaling $2.54 billion and $2.43 billion, respectively. At September 30, 2017 and December 31, 2016, the securities portfolio represented approximately 26% of total assets.

The investment securities portfolio primarily consists of Treasury securities, U.S. government agency securities, U.S. government sponsored agency mortgage-backed securities, non-agency mortgage-backed securities, corporate securities, municipal securities and asset-backed securities. Mortgage-backed securities rely on the underlying pools of mortgage loans to provide a cash flow of principal and interest. The actual maturities of these securities will usually differ from contractual maturities because loans underlying the securities can prepay. Decreases in interest rates will generally cause an acceleration of prepayment levels. In a declining or prolonged low interest rate environment, United may not be able to reinvest the proceeds from these prepayments in assets that have comparable yields. In a rising rate environment, the opposite occurs - prepayments tend to slow and the weighted average life extends. This is referred to as extension risk which can lead to lower levels of liquidity due to the delay of cash receipts and can result in the holding of a below market yielding asset for a longer period of time. United’s asset-backed securities include collateralized loan obligations and securities backed by student loans.

Management evaluates its securities portfolio each quarter to determine if any security is considered to be other than temporarily impaired. In making this evaluation, management considers its ability and intent to hold securities to recover current market losses. Losses on United’s fixed income securities at September 30, 2017 primarily reflect the effect of changes in interest rates. United did not recognize any other than temporary impairment losses on its investment securities during the third quarter of 2017 or 2016.

At September 30, 2017 and December 31, 2016, 16% and 22%, respectively, of the securities portfolio was invested in floating-rate securities or fixed-rate securities that were swapped to floating rates in order to manage exposure to rising interest rates.

Goodwill and Core Deposit Intangibles

Goodwill represents the premium paid for acquired companies above the fair value of the assets acquired and liabilities assumed, including separately identifiable intangible assets.

Core deposit intangibles, representing the value of acquired deposit relationships, are amortizing intangible assets that are required to be tested for impairment only when events or circumstances indicate that impairment may exist. There were no events or circumstances that led management to believe that any impairment exists in goodwill or other intangible assets.

Deposits

Total customer deposits, excluding brokered deposits, as of September 30, 2017 were $8.76 billion, compared to $8.31 billion at December 31, 2016. Total core transaction deposits (demand, NOW, money market and savings deposits, excluding public funds deposits) of $6.45 billion at September 30, 2017 increased $532 million since December 31, 2016, partly due to the HCSB acquisition. United’s high level of service, as evidenced by its strong customer satisfaction scores, has been instrumental in attracting and retaining core transaction deposit accounts.

Borrowing Activities

The Bank is a shareholder in the Federal Home Loan Bank of Atlanta (“FHLB”). Through this affiliation, FHLB secured advances totaled $494 million and $709 million, respectively, as of September 30, 2017 and December 31, 2016. United anticipates continued use of this short and long-term source of funds. Additional information regarding FHLB advances is provided in Note 13 to the consolidated financial statements included in United’s Annual Report on Form 10-K for the year ended December 31, 2016.

Contractual Obligations

There have not been any material changes to United’s contractual obligations since December 31, 2016.

Off-Balance Sheet Arrangements

United is a party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of customers. These financial instruments include commitments to extend credit, letters of credit and financial guarantees.

A commitment to extend credit is an agreement to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Letters of credit and financial guarantees are conditional commitments issued to guarantee a customer’s performance to a third party and have essentially the same credit risk as extending loan facilities to customers. Those commitments are primarily issued to local businesses.

59

The exposure to credit loss in the event of nonperformance by the other party to the commitments to extend credit, letters of credit and financial guarantees is represented by the contractual amount of these instruments. United uses the same credit underwriting procedures for making commitments, letters of credit and financial guarantees, as it uses for underwriting on-balance sheet instruments. Management evaluates each customer’s creditworthiness on a case-by-case basis and the amount of the collateral, if deemed necessary, is based on the credit evaluation. Collateral held varies, but may include unimproved and improved real estate, certificates of deposit, personal property or other acceptable collateral.

All of these instruments involve, to varying degrees, elements of credit risk in excess of the amount recognized in the balance sheet. The total amount of these instruments does not necessarily represent future cash requirements because a significant portion of these instruments expire without being used. United is not involved in off-balance sheet contractual relationships, other than those disclosed in this report, that could result in liquidity needs or other commitments, or that could significantly affect earnings. See Note 14 to the consolidated financial statements for additional information on off-balance sheet arrangements.

Interest Rate Sensitivity Management

The absolute level and volatility of interest rates can have a significant effect on profitability. The objective of interest rate risk management is to identify and manage the sensitivity of net interest revenue to changing interest rates, consistent with United’s overall financial goals. Based on economic conditions, asset quality and various other considerations, management establishes tolerance ranges for interest rate sensitivity and manages within these ranges.

United’s net interest revenue, and the fair value of its financial instruments, are influenced by changes in the level of interest rates. United limits its exposure to fluctuations in interest rates through policies developed by the Asset/Liability Management Committee (“ALCO”) and approved by the Board of Directors. ALCO meets periodically and has responsibility for formulating and recommending asset/liability management policies to the Board of Directors, formulating and implementing strategies to improve balance sheet positioning and/or earnings, and reviewing interest rate sensitivity.

One of the tools management uses to estimate and manage the sensitivity of net interest revenue to changes in interest rates is an asset/liability simulation model. Resulting estimates are based upon a number of assumptions for each scenario, including loan and deposit re-pricing characteristics and the rate of prepayments. ALCO periodically reviews the assumptions for reasonableness based on historical data and future expectations; however, actual net interest revenue may differ from model results. The primary objective of the simulation model is to measure the potential change in net interest revenue over time using multiple interest rate scenarios. The base scenario assumes rates remain flat and is the scenario to which all others are compared in order to measure the change in net interest revenue. Policy limits are based on immediate rate shock scenarios, as well as gradually rising and falling rate scenarios, which are all compared to the base scenario. Another commonly analyzed scenario is a most-likely scenario that projects the expected change in rates based on the slope of the forward yield curve. Other scenarios analyzed may include delayed rate shocks, yield curve steepening or flattening, or other variations in rate movements. While the primary policy scenarios focus on a twelve month time frame, longer time horizons are also modeled.

United’s policy is based on the 12-month impact on net interest revenue of interest rate shocks and ramps that increase from 100 to 400 basis points or decrease 100 basis points from the base scenario. In the shock scenarios, rates immediately change the full amount at the scenario onset. In the ramp scenarios, rates change by 25 basis points per month. United’s policy limits the projected change in net interest revenue over the first 12 months to a 5% decrease for each 100 basis point change in the increasing and decreasing rate ramp and shock scenarios. Historically low rates on September 30, 2016 made use of the down scenarios irrelevant. The following table presents United’s interest sensitivity position at the dates indicated.

Table 13 - Interest Sensitivity

	Increase (Decrease) in Net Interest Revenue from Base Scenario at September 30,
	2017						2016
Change in Rates	Shock			Ramp			Shock			Ramp
100 basis point increase		0.6	%		0.0	%		0.6	%		0.0	%
100 basis point decrease		(8.7	)		(6.7	)		n/a			n/a

Interest rate sensitivity is a function of the re-pricing characteristics of the portfolio of assets and liabilities. These re-pricing characteristics are the time frames within which the interest-earning assets and interest-bearing liabilities are subject to change in interest rates either at replacement, re-pricing or maturity. Interest rate sensitivity management focuses on the maturity structure of assets and liabilities and their re-pricing characteristics during periods of changes in market interest rates. Effective interest rate sensitivity management seeks to ensure that both assets and liabilities respond to changes in interest rates on a net basis within an acceptable timeframe, thereby minimizing the potentially adverse effect of interest rate changes on net interest revenue.

United has some discretion in the extent and timing of deposit re-pricing depending upon the competitive pressures in the markets in which it operates. Changes in the mix of earning assets or supporting liabilities can either increase or decrease the net interest margin without affecting interest rate sensitivity. The interest rate spread between an asset and its supporting liability can vary significantly even when the timing of re-pricing for both the asset and the liability remains the same, due to the two instruments re-pricing according to different indices. This is commonly referred to as basis risk.

60

Management uses derivative financial instruments to assist in the management of interest rate sensitivity. Derivative financial instruments can be a cost-effective and capital-effective means of modifying the re-pricing characteristics of on-balance sheet assets and liabilities. These contracts generally consist of interest rate swaps under which United pays a variable rate (or fixed rate, as the case may be) and receives a fixed rate (or variable rate, as the case may be), interest rate caps that fix the maximum amount of interest paid on a variable rate borrowing and interest rate floors that fix the minimum amount of interest received for floating rate loans. In addition to derivative instruments, management uses a variety of balance sheet instruments to manage interest rate risk such as investment securities, wholesale funding, and bank-issued deposits.

Derivative financial instruments that are designated as accounting hedges are classified as either cash flow or fair value hedges. The change in fair value of cash flow hedges is recognized in other comprehensive income. Fair value hedges recognize in earnings both the effect of the change in the fair value of the derivative financial instrument and the offsetting effect of the change in fair value of the hedged asset or liability associated with the particular risk of that asset or liability being hedged. United has other derivative financial instruments that are not designated as accounting hedges but are used for interest rate risk management purposes and as effective economic hedges. Derivative financial instruments that are not accounted for as accounting hedges are marked to market through earnings.

From time to time, United will terminate hedging positions when conditions change and the position is no longer necessary to manage overall sensitivity to changes in interest rates. In those situations where the terminated contract was in an effective hedging relationship at the time of termination and the hedging relationship is expected to remain effective throughout the original term of the contract, the resulting gain or loss is amortized over the remaining life of the original contract. For swap contracts, the gain or loss is amortized over the remaining original contract term using the straight line method of amortization. United expects that $545,000 will be reclassified as an increase to interest expense from other comprehensive income over the next twelve months related to these terminated cash flow hedges.

United’s policy requires all non-customer facing derivative financial instruments be used only for asset/liability management through the hedging of specific transactions or positions, and not for trading or speculative purposes. Management believes that the risk associated with using derivative financial instruments to mitigate interest rate risk sensitivity is appropriately monitored and controlled and will not have any material adverse effect on financial condition or results of operations. In order to mitigate potential credit risk, from time to time United may require the counterparties to derivative contracts to pledge cash and/or securities as collateral to cover the net exposure.

Liquidity Management

The objective of liquidity management is to ensure that sufficient funding is available, at a reasonable cost, to meet ongoing operational cash needs and to take advantage of revenue producing opportunities as they arise. While the desired level of liquidity will vary depending upon a variety of factors, it is the primary goal of United to maintain a sufficient level of liquidity in all expected economic environments. To assist in determining the adequacy of its liquidity, United performs a variety of liquidity stress tests including idiosyncratic, systemic and combined scenarios for both moderate and severe events. Liquidity is defined as the ability to convert assets into cash or cash equivalents without significant loss and to raise additional funds by increasing liabilities. Liquidity management involves maintaining the ability to meet the daily cash flow requirements of customers, both depositors and borrowers. United maintains an unencumbered liquid asset reserve to help ensure its ability to meet its obligations under normal conditions for at least a 12-month period and under severely adverse liquidity conditions for a minimum of 30 days.

An important part of the Bank’s liquidity resides in the asset portion of the balance sheet, which provides liquidity primarily through loan interest and principal repayments and the maturities and sales of securities, as well as the ability to use these assets as collateral for borrowings on a secured basis. The Bank also maintains excess funds in short-term interest-bearing assets that provide additional liquidity.

The Bank’s main source of liquidity is customer interest-bearing and noninterest-bearing deposit accounts. Liquidity is also available from wholesale funding sources consisting primarily of Federal funds purchased, FHLB advances, brokered deposits and securities sold under agreements to repurchase. These sources of liquidity are generally short-term in nature and are used as necessary to fund asset growth and meet other short-term liquidity needs.

In addition, because United’s holding company is a separate entity and apart from the Bank, it must provide for its own liquidity. United’s holding company is responsible for the payment of dividends declared for its common shareholders, and interest and principal on any outstanding debt or trust preferred securities. United’s holding company currently has internal capital resources to meet these obligations. While United’s holding company has access to the capital markets, the ultimate source of holding company liquidity is subsidiary service fees and dividends from the Bank, which are limited by applicable law and regulations.

At September 30, 2017, United had cash and cash equivalent balances of $247 million and had sufficient qualifying collateral to increase FHLB advances by $834 million and Federal Reserve discount window borrowing capacity of $1.17 billion. United also has the ability to raise substantial funds through brokered deposits. In addition to these wholesale sources, United has the ability to attract retail deposits by competing more aggressively on pricing.

61

As disclosed in the consolidated statement of cash flows, net cash provided by operating activities was $147 million for the nine months ended September 30, 2017. Net income of $79.7 million for the nine month period included deferred income tax expense of $51.8 million, and non-cash expenses for the following: depreciation, amortization and accretion of $20.1 million and stock-based compensation expense of $4.36 million. Other sources of cash from operating activities included a decrease in other assets and accrued interest receivable of $4.11 million. These sources of cash from operating activities were offset by a decrease in accrued expenses and other liabilities of $8.38 million. Net cash used in investing activities of $198,000 consisted primarily of a $57.3 million net increase in loans, purchases of investment securities available-for-sale totaling $710 million and purchases of investment securities held-to-maturity of $21.6 million. These uses of cash were partially offset by $44.9 million in proceeds from maturities and calls of investment securities held-to-maturity, $276 million in proceeds from the sale of investment securities available-for-sale and $466 million in proceeds from maturities and calls of investment securities available-for-sale. Net cash used in financing activities of $117 million consisted primarily of a net decrease in FHLB advances of $239 million, repayment of long-term debt of $40.0 million, and $18.7 million in dividends to common shareholders, partially offset by a net increase in deposits of $172 million. In the opinion of management, United’s liquidity position at September 30, 2017, was sufficient to meet its expected cash flow requirements.

Capital Resources and Dividends

Shareholders’ equity at September 30, 2017 was $1.22 billion, an increase of $145 million from December 31, 2016 due to year-to-date earnings less dividends declared, stock issued for the HCSB acquisition, an increase in the value of available-for-sale securities and the release of the disproportionate tax effect related to terminated cash flow hedges. Accumulated other comprehensive loss, which includes unrealized gains and losses on securities available-for-sale, the unrealized gains and losses on derivatives qualifying as cash flow hedges and unamortized prior service cost and actuarial gains and losses on United’s modified retirement plan, is excluded in the calculation of regulatory capital adequacy ratios.

The following table shows United’s capital ratios, as calculated under applicable regulatory guidelines, at September 30, 2017 and December 31, 2016. As of September 30, 2017, capital levels remained characterized as “well-capitalized” under the Basel III Capital Rules in effect at the time.

Effect of Inflation and Changing Prices

A bank’s asset and liability structure is substantially different from that of an industrial firm in that primarily all assets and liabilities of a bank are monetary in nature with relatively little investment in fixed assets or inventories. Inflation has an important effect on the growth of total assets and the resulting need to increase equity capital at higher than normal rates in order to maintain an appropriate equity to assets ratio.

Management believes the effect of inflation on financial results depends on United's ability to react to changes in interest rates, and by such reaction, reduce the inflationary effect on performance. United has an asset/liability management program to manage interest rate sensitivity. In addition, periodic reviews of banking services and products are conducted to adjust pricing in view of current and expected costs.

Item 3. Quantitative and Qualitative Disclosure About Market Risk

There have been no material changes in United’s market risk as of September 30, 2017 from that presented in the Annual Report on Form 10-K for the year ended December 31, 2016. The interest rate sensitivity position at September 30, 2017 is included in management’s discussion and analysis on page 59 of this report.

Item 4. Controls and Procedures

United’s management, including the Chief Executive Officer and Chief Financial Officer, supervised and participated in an evaluation of United’s disclosure controls and procedures as of September 30, 2017. Based on, and as of the date of that evaluation, United’s Chief Executive Officer and Chief Financial Officer have concluded that the disclosure controls and procedures were effective in accumulating and communicating information to management, including the Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosures of that information under the SEC’s rules and forms and that the disclosure controls and procedures are designed to ensure that the information required to be disclosed in reports that are filed or submitted by United under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms.

Part II. Other Information

Item 1. Legal Proceedings

In the ordinary course of operations, United and the Bank are defendants in various legal proceedings. Additionally, in the ordinary course of business, United and the Bank are subject to regulatory examinations and investigations. Based on our current knowledge and advice of counsel, in the opinion of management there is no such pending or threatened legal matter which would result in a material adverse change in the consolidated financial condition or results of operations of United.

Item 1A. Risk Factors

There have been no material changes from the risk factors previously disclosed in United’s Annual Report on Form 10-K for the year ended December 31, 2016.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds

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. As of September 30, 2017, the remaining authorization was $36.3 million. In November of 2017, the Board of Directors extended this program through December 31, 2018.

The following table contains information for shares repurchased during the third quarter of 2017.

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 nine months ended September 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.

Accounting Standards Updates and Recently Adopted Standards

Accounting Standards Updates [Abstract]

Accounting Standards Updates and Recently Adopted Standards

Note 2 –Accounting Standards Updates and Recently Adopted Standards

Accounting Standards Updates

In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers.  This ASU provides guidance on the recognition of revenue from contracts with customers.  The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services.  This guidance is effective for public entities for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period, and will be applied retrospectively either to each prior reporting period or with a cumulative effect recognized at the date of initial application. Because the guidance does not apply to revenue associated with financial instruments, including loans and securities, United does not expect the new revenue recognition guidance to have a material impact on the consolidated financial statements. United continues to evaluate the changes in disclosures required by the new guidance.

In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). This update requires a lessee to recognize in the statement of financial position a liability to make lease payments (the lease liability) and a right-of-use asset representing its right to use the underlying asset for the lease term. For leases with a term of 12 months or less, a lessee is permitted to make an accounting policy election not to recognize lease assets and lease liabilities. For public entities, this update is effective for fiscal years beginning after December 15, 2018, with modified retrospective application to prior periods presented. Upon adoption, United expects to report higher assets and liabilities as a result of including leases on the consolidated balance sheet. At December 31, 2016, future minimum lease payments amounted to $29.1 million. United does not expect the new guidance to have a material impact on the consolidated statement of income or the consolidated statement of shareholders’ equity.

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. The new guidance replaces the incurred loss impairment methodology in current GAAP with an expected credit loss methodology and requires consideration of a broader range of information to determine credit loss estimates. Financial assets measured at amortized cost will be presented at the net amount expected to be collected by using an allowance for credit losses. Purchased credit impaired loans will receive an allowance account at the acquisition date that represents a component of the purchase price allocation. Credit losses relating to available-for-sale debt securities will be recorded through an allowance for credit losses, with such allowance limited to the amount by which fair value is below amortized cost. Application of this update will primarily be on a modified retrospective approach, although the guidance for debt securities for which an other-than-temporary impairment has been recognized before the effective date and for loans previously covered by ASC 310-30, Receivables – Loans and Debt Securities Acquired with Deteriorated Credit Quality will be applied on a prospective basis. For public entities, this update is effective for fiscal years beginning after December 15, 2019. Upon adoption, United expects that the allowance for credit losses will be higher given the change to estimated losses for the estimated life of the financial asset, however management is still in the process of determining the magnitude of the increase. Management has formed a steering committee and has begun developing a project plan to ensure it is prepared for implementation by the effective date.

In March 2017, the FASB issued ASU No. 2017-07, Compensation – Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost. This ASU requires that an employer disaggregate the service cost component from the other components of net benefit cost. The amendments also provide explicit guidance on how to present the service cost component and the other components of net benefit cost and allow only the service cost component to be eligible for capitalization. For public entities, this update is effective for fiscal years beginning after December 15, 2017, with retrospective presentation of the service cost and other components and prospective application for any capitalization of service cost. The adoption of this update is not expected to have a material impact on the consolidated financial statements.

In March 2017, the FASB issued ASU No. 2017-08, Receivables – Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities. This update shortens the amortization period for certain callable debt securities held at a premium. Specifically, the amendments require the premium to be amortized to the earliest call date. For securities held at a discount, the discount will continue to be amortized to maturity. For public entities, this update is effective for fiscal years beginning after December 15, 2018, with modified retrospective application. The adoption of this update is not expected to have a material impact on the consolidated financial statements.

In May 2017, the FASB issued ASU No. 2017-09, Compensation – Stock Compensation (Topic 718): Scope of Modification Accounting. This update clarifies which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting. Specifically, modification accounting should be applied unless the fair value of the modified award is the same as the original award immediately before modification, the vesting conditions of the modified award are the same as the original award immediately before modification, and the classification of the modified award as an equity instrument or a liability instrument is the same as the classification of the original award immediately before modification. For public entities, this update is effective for fiscal years beginning after December 15, 2017, with prospective application. The adoption of this update is not expected to have a material impact on the consolidated financial statements.

In August 2017, The FASB issued ASU No. 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities. This update expands and refines hedge accounting for both nonfinancial and financial risk components and aligns the recognition and presentation of the effects of the hedging instrument and the hedged item in the financial statements. This update also makes certain targeted improvements to simplify the application of hedge accounting guidance and ease the administrative burden of hedge documentation requirements and assessing hedge effectiveness. For public entities, this update is effective for fiscal years beginning after December 15, 2018. For cash flow and net investment hedges existing at the date of adoption, an entity should apply a cumulative-effect adjustment related to eliminating the separate measurement of ineffectiveness to accumulated other comprehensive income with a corresponding adjustment to the opening balance of retained earnings. The amended presentation and disclosure guidance is required prospectively. The adoption of this update is not expected to have a material impact on the consolidated financial statements.

Recently Adopted Standards

In March 2016, the FASB issued ASU No. 2016-09, Compensation – Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. This update simplified several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. United adopted this standard effective January 1, 2017, with no material impact on the consolidated financial statements, although management expects more volatility in the effective tax rate as excess tax benefits and deficiencies on stock compensation transactions flow through income tax expense rather than capital surplus. United prospectively adopted the amendment requiring that excess tax benefits and deficiencies be recognized as income tax expense or benefit in the income statement and as an operating activity in the statement of cash flows. In addition, United elected to account for forfeitures as they occur, rather than estimate the number of awards expected to vest. United retrospectively implemented the clarification that cash paid by an employer when directly withholding shares for tax-withholding purposes should be classified as a financing activity.

Acquisitions

Note 3 – Acquisitions

Acquisition of HCSB Financial Corporation

On July 31, 2017, United completed the acquisition of HCSB Financial Corporation (“HCSB”) and its wholly-owned bank subsidiary, Horry County State Bank. HCSB operated eight branches in coastal South Carolina. In connection with the acquisition, United acquired $390 million of assets and assumed $347 million of liabilities. Under the terms of the merger agreement, HCSB shareholders received .0050 shares of United common stock for each share of HCSB common stock issued and outstanding at the closing date. 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 $23.9 million, representing the intangible value of HCSB’s 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 $3.48 million using the sum-of-the-years-digits method over six years, which represents the expected useful life of the asset. United will amortize the related noncompete agreements of $2.24 million using the straight line method over the terms of the agreements, which vary between one year and two years.

United’s operating results for the period ended September 30, 2017 include the operating results of the acquired assets and assumed liabilities for the period subsequent to the acquisition date of July 31, 2017.

The purchased assets and assumed liabilities were recorded at their acquisition date fair values and are summarized in the table below (in thousands).

At September 30, 2017, there were 116 available-for-sale securities and 37 held-to-maturity securities that were in an unrealized loss position. 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, 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 nine months ended September 30, 2017 or 2016.

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, 2017 and 2016 (in thousands).

At September 30, 2017 and December 31, 2016, loans totaling $3.57 billion and $3.33 billion, respectively, were pledged as collateral to secure Federal Home Loan Bank advances and other contingent funding sources.

At September 30, 2017, the carrying value and outstanding balance of purchased credit impaired (“PCI”) loans accounted for under ASC 310-30 were $68.7 million and $104 million, respectively. At December 31, 2016, the carrying value and outstanding balance of PCI loans were $62.8 million and $87.9 million, respectively. The following table presents changes in the value of the accretable yield for PCI loans for the periods indicated (in thousands):

	Three Months Ended September 30,						Nine Months Ended September 30,
	2017			2016			2017			2016
Balance at beginning of period	$	11,365		$	5,337		$	7,981		$	4,279

Balance at end of period	$	14,598		$	8,151		$	14,598		$	8,151

In addition to the accretable yield on PCI loans, the fair value adjustments on purchased loans outside the scope of ASC 310-30 are also accreted to interest revenue over the life of the loans. At September 30, 2017 and December 31, 2016, the remaining accretable fair value marks on loans acquired through a business combination and not accounted for under ASC 310-30 were $9.19 million and $7.14 million, respectively. In addition, indirect auto loans purchased at a premium outside of a business combination have a remaining premium of $9.19 million and $11.4 million, respectively, as of September 30, 2017 and December 31, 2016. During the three months ended September 30, 2017, United did not purchase indirect auto loans. During the nine months ended September 30, 2017, United purchased indirect auto loans of $81.7 million. During the three and nine months ended September 30, 2016, United purchased indirect auto loans of $38.8 million and $149 million, respectively.

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.

Management individually evaluates for impairment all non-PCI relationships that are on nonaccrual with a balance of $500,000 or greater, all troubled debt restructurings (“TDRs”), and all accruing substandard loans greater than $2 million. 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.

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.

As of September 30, 2017 and December 31, 2016, $2.98 million and $2.90 million, respectively, of specific reserves were allocated to customers whose loan terms have been modified in TDRs. United committed to lend additional amounts totaling up to $45,000 and $95,000, respectively, at September 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 nine months ended September 30, 2017 and 2016 are presented in the table below. In addition, the following table presents loans modified under the terms of a TDR that defaulted (became 90 days or more delinquent) during the periods presented and were initially restructured within one year prior to default (dollars in thousands).

TDRs that subsequently default and are placed on nonaccrual are charged down to the fair value, less costs of disposal, of the collateral consistent with United’s policy for nonaccrual loans.

Nonaccrual loans include both homogeneous loans that are collectively evaluated for impairment and individually evaluated impaired loans, based on the size of the loan. 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 September 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 $291,000 and $262,000 for the three months ended September 30, 2017 and 2016, respectively, and $814,000 and $686,000 for the nine months ended September 30, 2017 and 2016, respectively.

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. Loans in this category are presently protected from apparent loss; however, weaknesses exist that could cause future impairment, including the deterioration of financial ratios, past due status and questionable management capabilities. These loans require more than the ordinary amount of supervision. Collateral values generally afford adequate coverage, but may not be immediately marketable.

Substandard. These loans are inadequately protected by the current net worth and paying capacity of the obligor or by the collateral pledged. Specific and well-defined weaknesses exist that may include poor liquidity and deterioration of financial ratios. The loan may be past due and related deposit accounts experiencing overdrafts. There is the distinct possibility that United will sustain some loss if deficiencies are not corrected. If possible, immediate corrective action is taken.

Doubtful. Specific weaknesses characterized as Substandard that are severe enough to make collection in full highly questionable and improbable. There is no reliable secondary source of full repayment.

Loss. Loans categorized as Loss have the same characteristics as Doubtful; however, probability of loss is certain. Loans classified as Loss are charged off.

Consumer Purpose Loans. United applies a pass / fail grading system to all consumer purpose loans. Under the pass / fail grading system, consumer purpose loans that become past due 90 days or are in bankruptcy are classified as “fail” and all other loans are classified as “pass”. For reporting purposes, consumer purpose loans classified as “fail” are reported in the substandard column and all other consumer purpose loans are reported in the “pass” column.

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 as of the dates indicated is as follows (in thousands).

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 in 2017 or the third 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).

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 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

Offsetting positions for de-designated hedges	Derivative assets		-		1,977
		$	20,905	$	23,423

Mortgage banking - forward sales commitment	Derivative liabilities		3		96
Dealer offsets to bifurcated embedded derivatives	Derivative liabilities		13,210		14,341
De-designated hedges	Derivative liabilities		297		1,980
		$	21,110	$	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 September 30, 2017 and December 31, 2016 United did not have any designated 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 $545,000 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).

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, 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 September 30, 2017, United had one interest rate swap with a notional value of $30.0 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 nine months ended September 30, 2017, United recognized net losses of $160,000 and $612,000, respectively, related to ineffectiveness in the fair value hedging relationships. 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. United also recognized net reductions of interest expense of $40,000 and $137,000, respectively, for the three and nine months ended September 30, 2017 and net reductions of interest expense of $388,000 and $1.63 million, respectively, for the three and nine months ended September 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 nine months ended September 30, 2017 of $71,000 and $244,000, respectively, and reductions of interest revenue on securities during the three and nine months ended September 30, 2016 of $262,000 and $508,000, 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 income for the periods indicated (in thousands).

		$	(615	)	$	737		$	3		$	1,628

In certain cases, the estate of deceased brokered certificate of deposit holders may put the certificate of deposit back to United at par upon the death of the holder. When these estate puts occur, a gain or loss is recognized for the difference between the fair value and the par amount of the deposits put back. The change in the fair value of brokered time deposits that are being hedged in fair value hedging relationships reported in the table above includes gains and losses from estate puts 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, 2017, collateral totaling $20.9 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

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). Through September 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 September 30, 2017, 1.94 million additional shares remained available for grant under the plan.

The following table shows stock option activity for the first nine months of 2017.

Options	Shares			Weighted- Average Exercise Price		Weighted- Average Remaining Contractual Term (Years)		Aggregate Intrinisic Value ($000)
Outstanding at December 31, 2016		72,665		$	34.34
Expired		(1,538	)		147.60
Cancelled		(10,638	)		75.91
Outstanding at September 30, 2017		60,489			24.15		3.3	$	365
Exercisable at September 30, 2017		55,489			24.82		3.0		306

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, 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 $22,000 and $23,000, respectively, in compensation expense related to stock options during the nine months ended September 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 nine months of 2017 or 2016.

The table below presents restricted stock units activity for the first nine months of 2017.

Outstanding at December 31, 2016		690,970		$	18.60
Granted		259,220			26.48
Vested		(230,080	)		17.09			$	6,326
Cancelled		(9,965	)		19.99
Outstanding at September 30, 2017		710,145			22.06		3.2		20,268

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 nine months ended September 30, 2017 and 2016, expense of $4.13 million and $3.16 million, respectively, was recognized related to employee restricted stock unit awards. Of the expense recognized related to restricted stock unit awards during the nine months ended September 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 $3.43 million was recognized in compensation expense. In addition, for the nine months ended September 30, 2017 and 2016, $212,000 and $75,000, respectively, was recognized in other operating expense for restricted stock unit awards granted to members of United’s board of directors.

As of September 30, 2017, there was $12.4 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 3.14 years.

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, 2017 and 2016, 2,842 shares and 2,938 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 2017 and 2016, United issued 10,265 shares and 12,906 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, 2017 and December 31, 2016, 588,445 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 nine months of 2017, United did not repurchase any shares under the program. As of September 30, 2017, $36.3 million of United’s outstanding common stock may be repurchased under the program. In November of 2017, the Board of Directors extended this program through December 31, 2018.

Income Tax Disclosure [Abstract]

Income Taxes

Note 12 – Income Taxes

The income tax provision for the three and nine months ended September 30, 2017 was $15.7 million and $50.7 million, respectively, which represents effective tax rates of 36.0% and 38.9%, respectively, for each period. 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. 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 nine months of 2016.

At September 30, 2017 and December 31, 2016, United maintained a valuation allowance on its net deferred tax asset of $4.20 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 September 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 $4.20 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, 2017 that it was more likely than not that the net deferred tax asset of $129 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 2014. 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, 2017 and December 31, 2016, unrecognized income tax benefits totaled $3.87 million and $3.89 million, respectively.

Assets and Liabilities Measured at Fair Value

Sep. 30, 2017

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

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

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

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

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

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, impaired loans where an allowance is established based on the fair value of collateral require classification in the fair value hierarchy. When the fair value of the collateral is based on an observable market price or a current appraised value, United records the impaired loan as nonrecurring Level 2. When an appraised value is not available or management determines the fair value of the collateral is further impaired below the appraised value and there is no observable market price, United records the impaired loan as nonrecurring Level 3.

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, 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.

Pension Plan Assets

For information on the fair value of pension plan assets, see Note 18 in the Annual Report on Form 10-K for the year ended December 31, 2016.

Fair Value Option

At September 30, 2017, mortgage loans held for sale for which the fair value option was elected had an aggregate fair value and outstanding principal balance of $30.1 million and $29.1 million, respectively. 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 nine months ended September 30, 2017, net gains resulting from changes in fair value of these loans of $264,000 and $708,000, 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 nine months ended September 30, 2016, net gains resulting from changes in fair value of these loans of $11,000 were recorded in mortgage loan and other related fees.

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 September 30, 2017 and December 31, 2016, for which a nonrecurring fair value adjustment was recorded during the year-to-date periods presented (in thousands).

	Level 1		Level 2		Level 3		Total
September 30, 2017
Loans	$	-	$	-	$	8,843	$	8,843
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).

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 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).

Financial instruments whose contract amounts represent credit risk:

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, 2017, the Bank had invested $4.13 million in these limited partnerships and had committed to fund an additional $5.37 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.

Note 16 – Subsequent Events

On October 15, 2017, United paid off $35 million of maturing long-term debt that had an interest rate of 9%. On November 3, 2017, United's Board of Directors approved a regular quarterly cash dividend of ten cents per common share. The dividend is payable January 5, 2018, to shareholders of record on December 15, 2017.

Four Oaks Fincorp, Inc.

On November 1, 2017, United completed its previously announced acquisition of Four Oaks Fincorp, Inc. (“FOFN”) and its wholly-owned bank subsidiary, Four Oaks Bank & Trust Company. As of June 30, 2017, FOFN had total assets of $740 million, loans of $498 million and deposits of $560 million. Four Oaks Bank & Trust Company, which operated 14 banking offices in the Raleigh, North Carolina metropolitan statistical area, will operate under the Four Oaks Bank & Trust Company brand until the system conversions are completed in the second quarter of 2018, at which time it will begin to operate as United Community Bank.

Under the terms of the merger agreement, FOFN shareholders received .6178 shares of United common stock and $1.90 for each share of FOFN common stock, or an aggregate of approximately $128 million based on United’s closing price of $27.42 on October 31, 2017.

The acquisition will be accounted for as a business combination, subject to the provisions of ASC 805-10-50, Business Combinations. 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 nine months ended September 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.
