Assets and Liabilities Measured at Fair Value

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).

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, U.S. Treasury securities that are traded by dealers or brokers in active over-the-counter markets and money market funds. Level 2 securities include mortgage-backed securities issued by government sponsored entities, municipal bonds, corporate debt securities and asset-backed securities and are valued based on observable inputs that 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 are valued based on estimates obtained from broker-dealers.

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

Mortgage loans held for sale are carried at the lower of cost or market value. The fair value of mortgage loans held for sale is based on what secondary markets are currently offering for portfolios with similar characteristics.

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. 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.

Foreclosed Assets

Foreclosed assets are adjusted to fair value, less cost to sell, upon transfer of the loans to foreclosed assets. Subsequently, foreclosed assets are carried at the lower of carrying value or fair value. Fair value is based upon independent market prices, appraised values of the collateral or management’s estimation of the value of the collateral. When the fair value of the collateral is based on an observable market price or a current appraised value, United records the foreclosed asset 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 foreclosed asset 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 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.

The fair values of interest rate options are determined using the market standard methodology of discounting the future expected cash receipts that would occur if variable interest rates fell below the strike rate of the floors.  The variable interest rates used in the calculation of projected receipts on the floor are based on an expectation of future interest rates derived from observable market interest rate curves and volatilities.  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 United 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, 2013, United 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.  As a result, United has determined that its derivative valuations in their entirety are classified in Level 2 of the fair value hierarchy.

At March 31, 2014, United had two securities that have Level 3 valuations.  They are trust preferred securities in community banks that have shown deteriorating financial condition during the financial crisis, and both are currently deferring interest payments.  Since both investments are not actively traded, there is no recent trade activity upon which to assess value.  The values assigned to the investments are based on sales price estimates from brokers.  Both investments have a par amount of $1 million.  One was considered impaired in 2010 and was written down to $50,000 with a $950,000 impairment charge to earnings.  The other is carried at its original cost basis of $1 million with a $700,000 negative mark to fair value through other comprehensive income.  United does not consider this investment to be other-than-temporarily impaired, as the community bank was recapitalized by a private equity investment that management believes will result in full payment at maturity.

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 include assets that are measured at the lower of cost or market that were recognized at fair value below cost at the end of the period.  The table below presents United’s assets and liabilities measured at fair value on a nonrecurring basis as of March 31, 2014, December 31, 2013 and March 31, 2013, aggregated by the level in the fair value hierarchy within which those measurements fall (in thousands).

Loans that are reported above as being measured at fair value on a non-recurring 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.  Foreclosed properties that are included above as measured at fair value on a nonrecurring basis are those properties that resulted from a loan that had been charged down or have been written down subsequent to foreclosure.  Foreclosed properties are generally recorded at the lower of 80% of appraised value or 90% of the asking price which considers the estimated cost to sell.

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 the 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.

The short maturity of United’s assets and liabilities results in having a significant number of financial instruments whose fair value equals or closely approximates carrying value.  Such financial instruments are reported in the following balance sheet captions: cash and cash equivalents, mortgage loans held for sale and short-term borrowings.  The fair value of securities available-for-sale equals the balance sheet value.  Due to the short-term settlement of accrued interest receivable and payable, the carrying amount closely approximates fair value.

Fair value estimates are made at a specific point in time, based on relevant market information and information about the financial instrument.  These estimates do not reflect the premium or discount on any particular financial instrument that could result from the sale of United’s entire holdings.  Because no ready market exists for a significant portion of United’s financial instruments, fair value estimates are based on many judgments.  These estimates are subjective in nature and involve uncertainties and matters of significant judgment and therefore cannot be determined with precision.  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 financial instruments (commitments to extend credit and standby letters of credit) are generally short-term and at variable rates.  Therefore, both the carrying amount and the estimated fair value associated with these instruments are immaterial.

The carrying amount and fair values for other financial instruments that are not measured at fair value on a recurring basis in United’s balance sheet at March 31, 2014, December 31, 2013, and March 31, 2013 are as follows (in thousands).

Reclassifications

Reclassifications

Certain 2013 amounts have been reclassified to conform to the 2014 presentation.  During the fourth quarter of 2013, United reclassified hedge ineffectiveness gains and losses from other fee revenue to net interest revenue.  The impact of the reclassification has been reflected in all periods and was not material to any period.

Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity

In April 2014, the Financial Accounting Standards Board issued Accounting Standards Update (“ASU”) No. 2014-08, Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity.  This ASU limits the definition of discontinued operations to disposals of components of an entity that represent strategic shifts that have a major effect on an entity’s operations and financial results.  It also requires expanded disclosures for discontinued operations.  The standard is effective for disposals that occur within annual periods beginning on or after December 15, 2014, and interim periods within those years. This guidance is not expected to have a material impact on United’s financial position or results of operations.

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 three months ended March 31, 2014 and 2013, United accrued dividends on preferred stock, including accretion of discounts, as shown in the following table (in thousands).

	Three Months Ended

Series D - LIBOR plus 9.6875%, resets quarterly		280		419
Total preferred stock dividends	$	439	$	3,052

All preferred stock dividends are payable quarterly.

Series B preferred stock was issued at a discount. Dividend amounts shown include discount accretion for each period.

The preferred stock dividends were subtracted from net income in order to arrive at net income available to common shareholders.  There were no dilutive securities outstanding for the three months ended March 31, 2013.

The following table sets forth the computation of basic and diluted earnings per share for the three months ended March 31, 2014 and 2013 (in thousands, except per share data).

At March 31, 2014, United had the following potentially dilutive stock options and warrants outstanding: a warrant to purchase 219,909 common shares at $61.40 per share originally issued to the U.S. Treasury; 348,860 common shares issuable upon exercise of stock options granted to employees with a weighted average exercise price of $98.02; 1.10 million shares issuable upon completion of vesting of restricted stock awards; and warrants to purchase common stock equivalent junior preferred stock that would be convertible into 1,411,765 common shares exercisable at $21.25 per share granted to Fletcher International Ltd. (“Fletcher”) in connection with a 2010 asset purchase and sale agreement.  Pursuant to a settlement agreement with Fletcher, United has agreed to repurchase the warrant and resolve all claims between the parties.  The settlement agreement and the transactions contemplated thereby have been approved by the bankruptcy court but remain subject to an appeal.

At March 31, 2013, United had the following potentially dilutive stock options and warrants outstanding: a warrant to purchase 219,909 common shares at $61.40 per share originally issued to the U.S. Treasury; 129,670 common shares issuable upon exercise of warrants attached to trust preferred securities with an exercise price of $100 per share; 476,311 common shares issuable upon exercise of stock options granted to employees with a weighted average exercise price of $97.85; 497,800 shares issuable upon completion of vesting of restricted stock awards; warrants to purchase common stock equivalent junior preferred stock that would be convertible into 1,411,765 common shares exercisable at $21.25 per share granted to Fletcher in connection with a 2010 asset purchase and sale agreement; and 1,551,126 common shares issuable upon exercise of warrants granted in connection with United’s tax benefits preservation plan, exercisable at $12.50 per share.

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.  United’s derivative financial instruments are used to manage differences in the amount, timing, and duration of United’s known or expected cash receipts and its known or expected cash payments principally related to United’s loans, investment securities, wholesale borrowings and deposits.

In conjunction with the Financial Accounting Standards Board’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 United’s derivative financial instruments as well as their classification on the consolidated balance sheet as of March 31, 2014, December 31, 2013 and March 31, 2013 (in thousands).

Customer swap positions	Other assets	$	1,359	$	898	$	617
Dealer offsets to customer swap positions	Other assets		825		1,347		36
Bifurcated embedded derivatives	Other assets		13,753		12,867		—

Dealer offsets to bifurcated embedded derivatives	Other liabilities		18,931		18,324		—
		$	21,133	$	20,586	$	663

Derivative contracts that are not accounted for as hedging instruments under ASC 815, Derivatives and Hedging, and are described as “customer derivatives,” are between United and certain commercial loan customers with offsetting positions to dealers under a back-to-back swap program.  United also has three interest rate swap contracts that are not designated as hedging instruments but are economic hedges of market linked brokered certificates of deposit.  The market linked brokered certificates of deposit contain embedded derivatives that are bifurcated from the host instruments and marked to market through earnings.  The marks on the market linked swaps and the bifurcated embedded derivatives tend to move in opposite directions with changes in 90-day LIBOR and therefore provide an effective economic hedge.

Cash Flow Hedges of Interest Rate Risk

United’s objectives in using interest rate derivatives are to add stability to net interest revenue and to manage its exposure to interest rate movements. To accomplish this objective, United primarily uses interest rate swaps as part of its interest rate risk management strategy.  At March 31, 2014, United’s interest rate swaps designated as cash flow hedges involved the payment of fixed-rate amounts to a counterparty in exchange for United receiving variable-rate payments over the life of the agreements without exchange of the underlying notional amount.  United’s current cash flow hedges are for the purpose of converting variable rate deposits and wholesale borrowings to a fixed rate to protect United in a rising rate environment.  The swaps are forward starting with $100 million in notional  becoming effective in the first quarter of 2014 and the rest becoming effective later in 2014 and in 2015.  United had three swap contracts outstanding with a total notional amount of $200 million that were designated as cash flow hedges of three-month brokered deposits or other LIBOR based floating rate wholesale borrowings and three swap contracts outstanding with a total notional amount of $375 million that were designated as cash flow hedges of indexed money market accounts at March 31, 2014 and December 31, 2013. At March 31, 2013, United had three swap contracts outstanding with a notional amount of $200 million that were designated as cash flow hedges of future issuances of three-month brokered deposits or other LIBOR based floating-rate wholesale borrowings and two swap contracts outstanding with a total notional amount of $200 million that were designated as cash flow hedges of indexed money market accounts.

The effective portion of changes in the fair value of derivatives designated and that qualify as cash flow hedges is recorded in accumulated other comprehensive income and is subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings.  Amounts reported in accumulated other comprehensive income related to derivatives will be reclassified to interest expense when the swaps become effective, as interest payments are made on United’s LIBOR based, variable-rate wholesale borrowings and indexed deposit accounts.  United’s active cash flow hedges of floating rate liabilities began to become effective in the first quarter of 2014.  United recognized $35,000 in hedge ineffectiveness gains in deposit interest expense on active cash flow hedges during the first quarter of 2014.  No such hedge ineffectiveness gains or losses were recognized on active cash flow hedges during the first quarter of 2013.  United expects that $5.02 million will be reclassified as an increase to deposit interest expense over the next twelve months related to these cash flow hedges.

During the three months ended March 31, 2013, United accelerated the reclassification of $1,000 in gains from terminated positions, as a result of the forecasted transactions becoming probable not to occur.  These amounts are recognized in loan interest revenue as hedge ineffectiveness.  At March 31, 2014, there were no remaining unamortized balances from terminated positions.

Fair Value Hedges of Interest Rate Risk

United is exposed to changes in the fair value of certain of its fixed rate investments and 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 amounts 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 March 31, 2014, United had 24 interest rate swaps with an aggregate notional amount of $285 million that were designated as fair value hedges of interest rate risk.  Eight of the interest rate swaps outstanding at March 31, 2014 with an aggregate notional amount of $86 million were receive-variable / pay-fixed swaps that were used for the purpose of hedging changes in the fair value of corporate bonds resulting from changes in interest rates.  The other 16 were pay-variable / receive-fixed swaps hedging changes in the fair value of fixed rate brokered time deposits resulting from changes in interest rates.  At March 31, 2013, United had 18 interest rate swaps with an aggregate notional amount of $220 million that were designated as fair value hedges.  Two of the interest rate swaps with an aggregate notional amount of $21 million were receive-variable / pay-fixed swaps that were used for the purpose of hedging changes in the fair value of corporate bonds resulting from changes in interest rates.  The other 16 were pay-variable / receive-fixed swaps hedging changes in fair value of fixed rate brokered time deposits resulting from changes in interest rates.

For derivatives designated and that qualify as fair value hedges, the gain or loss on the derivative as well as the offsetting loss or gain on the hedged item attributable to the hedged risk are recognized in earnings. United includes the gain or loss on the hedged items in the same income statement line item as the offsetting loss or gain on the related derivatives.  During the three months ended March 31, 2014 and 2013 United recognized net losses of $389,000 and net losses of $86,000, respectively, related to ineffectiveness of the fair value hedging relationships.  United also recognized net reductions of interest expense of $1.21 million and $1.06 million, respectively, for the three months ended March 31, 2014 and 2013 related to United’s fair value hedges of brokered time deposits, which include net settlements on the derivatives.  United recognized reductions of interest revenue on securities during the first quarter of 2014 and 2013 in the amounts of $530,000 and $12,000, respectively, related to United’s 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 the issuing bank at par upon the death of the holder.  When these death 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 death 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 March 31, 2014, collateral totaling $35.8 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.

Accounting Standards Updates and Recently Adopted Standards

Note 2 –Accounting Standards Updates and Recently Adopted Standards

In April 2014, the Financial Accounting Standards Board issued Accounting Standards Update (“ASU”) No. 2014-08, Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity.  This ASU limits the definition of discontinued operations to disposals of components of an entity that represent strategic shifts that have a major effect on an entity’s operations and financial results.  It also requires expanded disclosures for discontinued operations.  The standard is effective for disposals that occur within annual periods beginning on or after December 15, 2014, and interim periods within those years. This guidance is not expected to have a material impact on United’s financial position or results of operations.

Commitments and Contingencies

Note 14 – Commitments and Contingencies

United and the Bank are parties to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of their 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 the Bank has in particular classes of financial instruments.  The exposure to credit loss in the event of nonperformance by the other party to the financial instrument for commitments to extend credit and letters of credit written is represented by the contractual amount of these instruments. United uses the same credit policies in making commitments and conditional obligations as it uses for underwriting on-balance sheet instruments. In most cases, collateral or other security is required to support financial instruments with credit risk.

The following table summarizes, as of March 31, 2014, December 31, 2013 and March 31, 2013, the contractual amount of off-balance sheet instruments (in thousands):

	March 31, 2014		December 31, 2013		March 31, 2013
Financial instruments whose contract amounts represent credit risk:
Commitments to extend credit	$	720,891	$	747,170	$	565,685
Letters of credit		19,960		19,846		12,818

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.

Stock-Based Compensation

Note 10 – Stock-Based Compensation

United has an equity compensation plan that allows for grants of incentive stock options, nonqualified stock options, restricted stock and restricted stock unit awards (also referred to as “nonvested stock” awards), stock awards, performance share awards or stock appreciation rights.  Options granted under the plan can have an exercise price no less than the fair market value of the underlying stock at the date of grant.  The general terms of the plan include a vesting period (usually four years) with an exercisable period not to exceed ten years.  Certain options, restricted stock and restricted stock unit awards provide for accelerated vesting if there is a change in control (as defined in the plan).  As of March 31, 2014, 525,800 additional awards could be granted under the plan. Through March 31, 2014, incentive stock options, nonqualified stock options, restricted stock and restricted stock unit awards, base salary stock grants and performance share awards have been granted under the plan.

The following table shows stock option activity for the first three months of 2014.

Options	Shares			Weighted- Average Exercise Price		Weighted-Average Remaining Contractual Term (Years)		Aggregate Intrinisic Value ($000)
Outstanding at December 31, 2013		350,772		$	97.87
Expired		(1,912	)		69.61
Outstanding at March 31, 2014		348,860			98.02		3.1	$	104
Exercisable at March 31, 2014		338,785			100.55		2.9		42

No stock options were granted during the three months ended March 31, 2014 or 2013.  Most of United’s outstanding stock options were granted prior to the economic downturn during which time United’s stock price decreased sharply.  The lower stock price has rendered most of United’s outstanding options severely out of the money and potentially worthless to the grantee.  Therefore, historical exercise patterns do not provide a reasonable basis for determining the expected life of new option grants.  United therefore uses the formula provided by the SEC in Staff Accounting Bulletin No. 107 to determine the expected life of options.

United recognized no compensation expense related to stock options in the three months ended March 31, 2014.  Compensation expense relating to stock options of $64,000 was included in earnings for the three months ended March 31, 2013.  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.  The forfeiture rate for new options issued is estimated to be approximately 3% per year.  No options were exercised during the first three months of 2014 or 2013.

The table below presents restricted stock activity for the first three months of 2014.

Restricted Stock	Shares			Weighted- Average Grant- Date Fair Value
Outstanding at December 31, 2013		1,073,676		$	13.73
Granted		25,750			19.14
Excercised		(1,667	)		10.77
Cancelled		(833	)		13.16
Outstanding at March 31, 2014		1,096,926			13.86
Vested at March 31, 2014		22,462			10.11

Compensation expense for restricted stock is based on the fair value of restricted stock awards at the time of grant, which is equal to the value of United’s common stock on the date of grant.  The value of restricted stock grants that are expected to vest is amortized into expense over the vesting period.  For the three months ended March 31, 2014 and 2013, compensation expense of $1.10 million and $445,000, respectively, was recognized related to restricted stock awards.  In addition, for the three months ended March 31, 2014 and 2013, $25,000 and $17,000, respectively, was recognized in other operating expense for restricted stock units granted to members of United’s board of directors.  The total intrinsic value of restricted stock was $21.4 million at March 31, 2014.

As of March 31, 2014, there was $11.9 million of unrecognized compensation cost related to non-vested stock options and restricted stock awards granted under the plan.  That cost is expected to be recognized over a weighted-average period of 3.32 years.  The aggregate grant date fair value of options and restricted stock awards that vested during the three months ended March 31, 2014, was $20,000.

Securities with a carrying value of $1.48 billion, $1.53 billion and $1.25 billion were pledged to secure public deposits and other secured borrowings at March 31, 2014, December 31, 2013 and March 31, 2013, respectively.  Substantial borrowing capacity remains available under borrowing arrangements with the Federal Home Loan Bank of Atlanta (“FHLB”) with currently pledged securities.

In the fourth quarter of 2013, securities available-for-sale with a fair value of $301 million were transferred to held-to-maturity.  The securities were transferred at their fair value on the date of transfer.  The unrealized loss of $8.31 million on the transferred securities is being amortized into interest revenue as an adjustment to the yield on those securities over the remaining life of the transferred securities.

The cost basis, gross unrealized gains and losses and fair value of securities held-to-maturity at March 31, 2014, December 31, 2013 and March 31, 2013 are as follows (in thousands).

Management evaluates securities for other-than-temporary impairment at least 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 months ended March 31, 2014 or 2013.

At March 31, 2014, there were 113 available-for-sale securities and 35 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 March 31, 2014 and December 31, 2013 were primarily attributable to changes in interest rates.  Unrealized losses at March 31, 2013 were primarily related to changes in interest rates; however, the unrealized losses in corporate bonds also reflect downgrades in the underlying securities ratings since the time of acquisition.  The bonds remain above investment grade and have recovered much of their initial market value loss. Therefore, United does not consider them to be impaired.

The amortized cost and fair value of held-to-maturity and available-for-sale securities at March 31, 2014, by contractual maturity, are presented in the following table (in thousands).

At March 31, 2014, December 31, 2013 and March 31, 2013, loans with a carrying value of $2.07 billion, $1.77 billion and $1.94 billion, respectively, were pledged as collateral to secure FHLB advances and other contingent funding sources.

During the second quarter of 2013, United executed a plan to accelerate the disposition of classified assets including performing classified loans, nonperforming loans and foreclosed properties.  The purpose of the accelerated classified asset disposition plan was to resolve legacy credit problems remaining from the recent financial crisis and to accelerate the improvement of United’s credit measures toward pre-crisis levels.  The classified asset sales included individual note and foreclosed property sales and a large bulk sale of classified assets to a single investor.  The bulk sale included performing and nonperforming classified loans and foreclosed properties.  The assets were divided into four separate pools that were bid separately by potential buyers.  A single purchaser was the high bidder for each of the four pools.  The table below shows the allocation among impaired loans, loans that were not considered impaired and foreclosed properties, including United’s recorded investment in those assets, the sales proceeds and the resulting net charge-offs of assets sold in the bulk sale transaction (in thousands).

	Recorded Investment		Net Sales Proceeds		Net Charge-Off
Loans considered impaired	$	96,829	$	56,298	$	(40,531	)
Loans not considered impaired		25,687		15,227		(10,460	)
Foreclosed properties		8,398		5,933		(2,465	)
Total assets sold	$	130,914	$	77,458	$	(53,456	)

The loans considered impaired in the table above were assigned specific reserves of $6.86 million in the most recent analysis of the allowance for loan losses prior to the sale.  Because the assets were sold at liquidation prices in a bulk transaction with no recourse, the sales price was generally lower than the appraised value of the foreclosed properties and loan collateral.  Although the classified asset sales increased charge-offs during the second quarter of 2013, they accomplished management’s goal of moving classified asset levels toward the pre-crisis range.

The allowance for loan losses represents management’s estimate of probable incurred losses in the loan portfolio as of the end of the period.  In 2013, United established an allowance for unfunded commitments separate from the allowance for loan losses due to significant growth in unfunded loan commitments.  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.

The following table presents the balance and activity in the allowance for credit losses by portfolio segment for the three months ended March 31, 2014 and 2013 (in thousands).

United considers all substandard loan relationships that are on nonaccrual with a balance of $500,000 or greater and all troubled debt restructurings (“TDRs”) to be individually impaired.  In addition, United reviews all accruing substandard loan relationships greater than $2 million to determine if the loan is individually impaired.  A loan is considered individually impaired when, based on current events and circumstances, it is probable that all amounts due, according to the contractual terms of the loan, will not be collected.  All TDRs are considered individually impaired regardless of accrual status.  Impairment is measured based on the present value of expected future cash flows, discounted at the loan’s effective interest rate, the loan’s observable market price, or the fair value of the collateral if the loan is collateral dependent.  A specific reserve is established for individually impaired loans for the amount of calculated impairment.  Interest payments received on individually impaired nonaccrual loans are applied as a reduction of the outstanding principal balance.  For impaired loans not on nonaccrual status, interest is accrued according to the terms of the loan agreement.  Loans are evaluated for individual impairment quarterly and specific reserves are established in the allowance for loan losses for any measured specific impairment on individually impaired loans.

Each quarter, United’s management prepares an analysis of the allowance for credit losses to determine the appropriate balance that measures and quantifies the amount of probable incurred loss in the loan portfolio.  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.  United uses eight quarters of historical loss experience weighted toward the most recent four quarters to determine the loss factors to be used in the reserve calculation for loans evaluated in the aggregate.  Eight quarters has been determined to be an appropriate time period as it is recent enough to be relevant to current conditions and covers a length of time sufficient to minimize distortions caused by nonrecurring and unusual activity that might otherwise influence a shorter time period.  In previous periods, the weighted average was calculated by multiplying each quarter’s annualized historical net charge-off rate by 1 through 8, with 8 representing the most recent quarter and 1 representing the oldest quarter.  United adopted this method of weighting quarterly loss rates to capture the rapidly deteriorating credit conditions in its loss factors during the financial crisis.  Now that credit conditions have begun to stabilize, management concluded in the first quarter of 2014 that it was appropriate to apply a more level weighting to capture the full range and impacts of credit losses experienced during the most recent economic and credit cycle.  Therefore in the first quarter of 2014, United applied different weighting factors to the eight quarters of losses.  For the four most recent quarters, United applied a weighting factor of 1.75.  For the four oldest quarters, United applied a weighting of 1.00 for each quarterly loss factor.  Management believes the current weightings are more appropriate to measure the unconfirmed losses incurred within the loan portfolio.

Also, beginning in the first quarter of 2014, United updated its measurement of the loss emergence period in the calculation of the allowance for credit losses.  The rapidly deteriorating credit conditions during the peak of the credit cycle shortened the length of time between management’s estimation of the incurrence of a loss and its recognition as a charge off.  In most cases, the loss emergence period was within a twelve month period which made the use of annualized loss factors appropriate for measuring the amount of incurred yet unconfirmed credit losses within the loan portfolio.  As United has moved out beyond the peak of the financial crisis, management has observed that the loss emergence period has extended. United calculates the loss emergence period for each pool of loans based on the average length of time between the date a loan first exceeds 30 days past due and the date the loan is charged off.

The updates to the weightings of the eight quarters of loss history and the update to our estimation of the loss emergence period did not have a material effect on the total allowance for loan losses or the provision for loan losses for the first quarter of 2014.  These updates resulted in the full allocation of the previously unallocated portion of the allowance for loan losses.

On junior lien home equity loans, United has limited ability to monitor the delinquency status of the first lien unless the first lien is also held by United.  As a result, United 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, acceleration or delays in timing of recognition of losses that may affect historical loss emergence periods, and other macro environmental factors such as changes in unemployment rates, lease vacancy rates and trends in property values and absorption rates.

United’s management believes that its method of determining the balance of the allowance for loan losses provides a reasonable and reliable basis for measuring and reporting losses that are inherent 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 charged off.  Full or partial charge-offs may also be recommended by the Collections Department, the Special Assets Department and the Foreclosure / OREO department.  Nonaccrual real estate loans that are collateral dependent are generally charged down to 80% of the appraised value of the underlying collateral at the time they are placed on nonaccrual status.

A committee consisting of the Chief Risk Officer, Senior Risk Officer and the Senior Credit Officers meets monthly to review charge-offs that have occurred during the previous month.

Closed-end retail loans (installment and residential mortgage loans) and open-end (revolving) retail loans past due 90 cumulative days are charged off unless the loan is secured and in process of collection (within the next 90 days).

There were no loans more than 90 days past due and still accruing interest at March 31, 2014, December 31, 2013 or March 31, 2013.  Nonaccrual loans include both homogeneous loans that are collectively evaluated for impairment and individually evaluated impaired loans.  United’s policy is to place loans on nonaccrual status when, in the opinion of management, the principal and interest on a loan is not likely to be repaid in accordance with the loan terms 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 outstanding principal.

The gross additional interest income that would have been earned if the loans classified as nonaccrual had performed in accordance with the original terms was approximately $460,000, and $1.14 million for the three months ended March 31, 2014 and 2013, respectively. The gross additional interest income that would have been earned in for the three months ended March 31, 2014 and 2013 had performing TDRs performed in accordance with the original terms is immaterial.

Collateral dependent TDRs that subsequently default and are placed on nonaccrual are charged down to the fair value of the collateral consistent with United’s policy for nonaccrual loans.  Impairment on TDRs that are not collateral dependent continues to be measured on discounted cash flows regardless of whether the loan has subsequently defaulted.

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 continuous 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.  Beginning in the first quarter of 2014, United began to apply a pass / fail grading system to all consumer purpose loans.  Under the pass / fail grading system, consumer purpose loans meeting the criteria of substandard 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 performing substandard or nonaccrual columns and all other consumer purpose loans are reported in the “pass” column.  The first quarter grading change resulted in decreases in loans categorized as “watch” for the consumer installment, residential mortgage and home equity lines of credit loan classifications.  Loan balances reported in the “watch” column for residential mortgage in the first quarter are generally commercial purpose loans secured by the borrower’s residence.

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

Income Taxes

3 Months Ended

Income Tax Disclosure [Abstract]

Income taxes

Note 12 – Income Taxes

The income tax provision for the three months ended March 31, 2014 was $9.04 million which represents an effective tax rate of 37.0%.  The income tax provision for the three months ended March 31, 2013 was $585,000 which represents an effective tax rate of 4.7%.  The first quarter 2013 tax provision was lower due to the full valuation allowance in United’s net deferred tax asset, most of which was reversed in the second quarter of 2013.  At March 31, 2014, December 31, 2013 and March 31, 2013, the valuation allowance on deferred tax assets was $4.08 million, $4.10 million and $271 million, respectively.  Management assesses the valuation allowance recorded against deferred tax assets at each reporting period.  The determination of whether a valuation allowance for deferred tax assets is appropriate is subject to considerable judgment and requires an evaluation of all the positive and negative evidence.

In the second quarter of 2013, United reversed $272 million of its valuation allowance on its net deferred tax asset.  United established a full valuation allowance on its net deferred tax asset in 2010 due to the realization of significant losses and uncertainty about United’s future earnings forecasts.

United evaluated the need for a valuation allowance again at March 31, 2014.  Based on the assessment of all the positive and negative evidence, management concluded that it is more likely than not that nearly all of the net deferred tax asset will be realized based upon future taxable income.  The remaining valuation allowance of $4.08 million is related to specific state income tax credits that have short carryforward periods and are expected to expire unused.  The positive evidence considered by management in arriving at the conclusion that a full valuation allowance is not necessary included consecutive profitable quarters beginning with the fourth quarter of 2011, United’s strong pre-crisis earnings history and growth in pre-tax, pre-credit earnings, which demonstrate demand for United’s products and services, and United’s significant improvement in credit measures, which improve both the sustainability of profitability and management’s ability to forecast future credit losses.  The negative evidence previously considered by management included a three-year cumulative loss position and informal memorandum of understanding (“MOU”) with the banking regulatory agencies.  The MOUs were terminated in the fourth quarter of 2013 and first quarter of 2014 and United exited the three-year cumulative loss position in the first quarter of 2014, based on a rolling twelve quarters.

The valuation allowance could fluctuate in future periods based on the assessment of the positive and negative evidence.  Management’s conclusion at March 31, 2014 that it was more likely than not that the net deferred tax assets of $244 million will be realized is based upon management’s estimate of future taxable income.  Management’s estimate of future taxable income is based on internal forecasts that consider historical performance, various internal estimates and assumptions, as well as certain external data all of which management believes to be reasonable although inherently subject to significant judgment.  If actual results differ significantly from the current estimates of future taxable income, even if caused by adverse macro-economic conditions, the valuation allowance may need to be increased for some or all of the deferred tax asset.  Such an increase to the 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 2010.  Although United is unable to determine the ultimate outcome of future examinations, United believes that the liability recorded for uncertain tax positions is appropriate.

At March 31, 2014, December 31, 2013 and March 31, 2013, unrecognized income tax benefits totaled $4.59 million, $4.50 million and $5.20 million, respectively.  In the first quarter of 2014, United adopted the provisions of ASU 2013-11, Presentations of an Unrecognized Tax Benefit when a Net Operating Loss Carryfoward, a Similar Tax Loss, or a Tax Credit Carryforward exists. ASU 2013-11 requires unrecognized tax benefits to be presented as a reduction of a deferred tax asset unless certain conditions are present. Prior to adoption, unrecognized tax benefits were presented as a component of the current tax liabilty payable. Upon adoption, United reclassified $4.59 million in unrecognized tax benefits from other liabilities to its net deferred tax asset. The reclassification resulted in decreases in United’s net deferred tax asset and other liabilities.

Summary Of Significant 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 of America (“GAAP”) and general banking industry practices.  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, 2013.

In management’s opinion, all accounting adjustments necessary to accurately reflect the financial position and results of operations on the accompanying financial statements have been made. These adjustments are normal and recurring accruals considered necessary for a fair and accurate presentation. The results for interim periods are not necessarily indicative of results for the full year or any other interim periods.

Reclassifications

Certain 2013 amounts have been reclassified to conform to the 2014 presentation.  During the fourth quarter of 2013, United reclassified hedge ineffectiveness gains and losses from other fee revenue to net interest revenue.  The impact of the reclassification has been reflected in all periods and was not material to any period.

Common and Preferred Stock Issued / Common Stock Issuable

3 Months Ended

Mar. 31, 2014

Equity [Abstract]

Common and Preferred Stock Issued / Common Stock Issuable

Note 11 – Common and Preferred Stock Issued / Common Stock Issuable

United sponsors a Dividend Reinvestment and Share Purchase Plan (“DRIP”) that allows participants who already own United’s common stock to purchase additional shares directly from United.  The DRIP also allows participants to automatically reinvest their quarterly dividends in additional shares of common stock without a commission.  The DRIP is currently suspended and no shares were issued in 2013 or the first quarter of 2014.

United’s 401(k) retirement plan regularly purchases shares of United’s common stock directly from United.  In addition, United has an Employee Stock Purchase Program that allows eligible employees to purchase shares of common stock at a 5% discount, with no commission charges.  For the three months ended March 31, 2014 and 2013, United issued 11,837 and 18,170 shares, respectively, and increased capital by $209,000 and $189,000, respectively, through these programs.

United offers its common stock as an investment option in its deferred compensation plan.  United also allows for the deferral of restricted stock 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 stock and settlement must be accomplished in shares at the time the deferral period is completed. At March 31, 2014 and 2013, 237,763 and 133,469 shares, respectively, were issuable under the deferred compensation plan.
