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. Foreclosed property is initially recorded at fair value, less the estimated cost to sell. If the fair value less the estimated cost 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 fair value less the estimated cost to sell of the foreclosed property decreases during the holding period, a valuation allowance is established with a charge to operating expenses. 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 the Financial Accounting Standards Board’s (“FASB”) Accounting Standards Codification (“ASC”) 360-20, Real Estate Sales. Certain 2012 amounts have been reclassified to conform to the 2013 presentation. The 2012 reclassifications were not material to the financial statement presentation.

Accounting Standards Updates [Abstract]
Accounting Standards Updates and Recently Adopted Standards	Note 2 –Accounting Standards Updates and Recently Adopted Standards In January 2013, the FASB issued Accounting Standards Update No. 2013-01, Clarifying the Scope of Disclosures about Offsetting Assets and Liabilities. This ASU limits the scope of the new balance sheet offsetting disclosures to derivatives, repurchase agreements, and securities lending transactions to the extent that they are (1) offset in the financial statements or (2) subject to an enforceable master netting agreement. The disclosure requirements were effective for annual reporting periods beginning on or after January 1, 2013 and interim periods within those annual periods. It did not have a material impact on United’s financial position or results of operations, and resulted in additional disclosures. In February 2013, the FASB issued Accounting Standards Update No. 2013-02, Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income. The amendments in this update require an entity to provide information about the amounts reclassified out of accumulated other comprehensive income by component and by the respective line items of net income. The standard was effective for fiscal years, and interim periods within those years, beginning after December 15, 2012. This guidance did not have a material impact on United’s financial position or results of operations, and resulted in additional disclosures. There were no Accounting Standards Updates issued by the FASB since the filing of United’s 2012 Annual Report on Form 10-K that were applicable to United.

- Definition

The entire disclosure for reporting accounting changes and error corrections. It includes the conveyance of information necessary for a user of the Company's financial information to understand all aspects and required disclosure information concerning all changes and error corrections reported in the Company's financial statements for the period.

Offsetting Assets and Liabilities

Note 3 – Offsetting Assets and Liabilities

United enters into reverse repurchase agreements in order to invest short-term funds. In addition, United enters into repurchase agreements and reverse repurchase agreements with the same counterparty in transactions commonly referred to as collateral swaps that are subject to master netting agreements under which the balances are netted in the balance sheet in accordance with ASC 210-20, Offsetting.

United also enters into derivative transactions that are subject to master netting arrangements; however there were no offsetting positions at March 31, 2013, December 31, 2012 or March 31, 2012.

The following table presents a summary of amounts outstanding under master netting agreements as of March 31, 2013 and December 31, 2012, and March 31, 2012 (in thousands).

Securities with a carrying value of $1.25 billion, $1.40 billion, and $1.38 billion were pledged to secure public deposits and other secured borrowings at March 31, 2013, December 31, 2012 and March 31, 2012, respectively. Substantial borrowing capacity remains available under borrowing arrangements with the FHLB with currently pledged securities.

Securities are classified as held-to-maturity when management has the positive intent and ability to hold them until maturity. Securities held-to-maturity are carried at amortized cost.

The amortized cost, gross unrealized gains and losses and fair value of securities held-to-maturity at March 31, 2013, December 31, 2012 and March 31, 2012 are as follows (in thousands).

At March 31, 2013, there were 68 available-for-sale securities and three 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, 2013, December 31, 2012 and March 31, 2012 were primarily attributable 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 United does not consider them to be impaired.

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, 2013 or 2012.

The amortized cost and fair value of held-to-maturity and available-for-sale securities at March 31, 2013, by contractual maturity, are presented in the following table (in thousands).

The Bank makes loans and extends credit to individuals and a variety of firms and corporations located primarily in counties in north Georgia, the Atlanta, Georgia metropolitan statistical area, the Gainesville, Georgia metropolitan statistical area, coastal Georgia, western North Carolina, east Tennessee and the Greenville, South Carolina metropolitan statistical area. Although the Bank has a diversified loan portfolio, a substantial portion of its loan portfolio is collateralized by improved and unimproved real estate and is dependent upon the real estate market.

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

Each quarter, United’s management prepares an analysis of the allowance for loan losses to determine the appropriate balance that measures and quantifies the amount of loss inherent in the loan portfolio. The allowance is comprised of specific reserves which are determined as described above, general reserves which are determined based on historical loss experience as adjusted for current trends and economic conditions and an unallocated portion. United uses eight quarters of historical loss experience weighted toward the most recent quarters to determine the loss factors to be used. 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 normalize for nonrecurring and unusual activity that might otherwise influence a shorter time period. The weighted average is 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 uses annualized charge-off rates under the broad assumption that losses inherent in the loan portfolio will generally be resolved within twelve months. Problem loans that are not resolved within twelve months are generally larger loans that are more complex in nature requiring more time to either rehabilitate or work out of the bank. These credits are subject to impairment testing and specific reserves.

The weighted loss factor results for each quarter are added together and divided by 36 (the sum of 1, 2, 3, 4, 5, 6, 7 and 8) to arrive at the weighted average historical loss factor for each category of loans. United calculates loss factors for each major category of loans (commercial real estate, commercial & industrial, commercial construction, residential construction and consumer installment) except residential real estate loans which are further divided into home equity first lien, home equity junior lien and all other residential real estate loans and a loss factor is calculated for each category.

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 render the use of annualized charge-off rates to be inappropriate, and other macro environmental factors such as changes in unemployment rates, lease vacancy rates and trends in property values and absorption rates.

To validate the results, management closely monitors the loan portfolio to determine the range of potential losses based upon probability of default and losses upon default for each major loan category. The potential range of losses resulting from this analysis is compared to the resulting loss factors for each major loan category to validate the loss factors and determine if qualitative adjustments are necessary. 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.

The following table presents the balance and activity in the allowance for loan losses by portfolio segment and the recorded investment in loans by portfolio segment based on the impairment method as of March 31, 2013, December 31, 2012 and March 31, 2012 (in thousands).

When a loan officer determines that a loan is uncollectible, he or she is responsible for recommending to the local bank president 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 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. The 10 largest charge-offs are reported quarterly to the Board of Directors.

Generally, closed-end retail loans (installment and residential mortgage loans) past due 120 cumulative days are charged-off unless the loan is well secured and in process of collection (within the next 90 days). Open-end (revolving) retail loans which are past due 180 cumulative days from their contractual due date are generally charged-off.

At March 31, 2013, December 31, 2012 and March 31, 2012, loans with a carrying value of $1.94 billion, $1.90 billion and $1.58 billion, respectively, were pledged as collateral to secure FHLB advances and other contingent funding sources.

There were no loans more than 90 days past due and still accruing interest at March 31, 2013, December 31, 2012 or March 31, 2012. 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 following table presents the recorded investment (unpaid principal less amounts charged-off) in nonaccrual loans by loan class as of March 31, 2013, December 31, 2012 and March 31, 2102 (in thousands).

As of March 31, 2013, December 31, 2012, and March 31, 2012, $8.12 million, $9.50 million and $12.2 million of specific reserves were allocated to customers whose loan terms have been modified in TDRs. United committed to lend additional amounts totaling up to $613,000, $689,000, and $891,000 as of March 31, 2013, December 31, 2012 and March 31, 2012, respectively, to customers with outstanding loans that are classified as TDRs.

The modification of the terms of the TDRs included one or a combination of the following: a reduction of the stated interest rate of the loan or an extension of the amortization period that would not otherwise be considered in the current market for new debt with similar risk characteristics; a permanent reduction of the principal amount; 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, or a mandated bankruptcy restructuring.

The following table presents additional information on TDRs including the number of loan contracts restructured and the pre- and post-modification recorded investment as of March 31, 2013, December 31, 2012 and March 31, 2012 (dollars in thousands).

Collateral dependent TDRs that subsequently default or are otherwise 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 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.

Loans not meeting the criteria above that are analyzed individually as part of the above described process are considered to be pass rated loans. Loans listed as not rated are generally deposit account overdrafts that have not been assigned a grade.

As of March 31, 2013, December 31, 2012 and March 31, 2012, and based on the most recent analysis performed, the risk category of loans by class of loans is as follows (in thousands).

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, 2013 and 2012, 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		419		419
Total preferred stock dividends	$	3,052	$	3,030

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 and 2012.

The following table sets forth the computation of basic and diluted earnings per share for the three months ended March 31, 2013 and 2012 (in thousands, except per share data).

Derivatives and Hedging Activities

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. 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, 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 net basis by counterparty portfolio.

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, 2013, December 31, 2012 and March 31, 2012 (in thousands).

Derivatives accounted for as hedges under ASC 815

		Fair Value
	Balance Sheet	March 31,		December 31,		March 31,
Interest Rate Products	Location	2013		2012		2012
Asset derivatives	Other assets	$	21	$	23	$	—
Liability derivatives	Other liabilities	$	13,964	$	11,900	$	2,526

Asset derivatives	Other assets	$	581	$	635	$	73
Liability derivatives	Other liabilities	$	592	$	643	$	73

Derivative contracts that are not accounted for as hedges under ASC 815, Derivatives and Hedging are between United and certain commercial loan customers with offsetting positions to dealers under a back-to-back swap program.

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, 2013, United’s interest rate swaps designated as cash flow hedges involve 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 and do not become effective until 2014. United had five swap contracts outstanding with a total notional amount of $400 million that were designated as cash flow hedges of brokered deposits at March 31, 2013 and December 31, 2012. United had no active derivative contracts outstanding at March 31, 2012, that were designated as cash flow hedges of interest rate risk.

The effective portion of changes in the fair value of derivatives designated as, 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 in 2014 as interest payments are made on United’s LIBOR based variable-rate wholesale borrowings and indexed deposit accounts. At March 31, 2013, a portion of the amount included in other comprehensive income represents deferred gains from terminated cash flow hedges where the forecasted hedging transaction is expected to remain effective over the remaining unexpired term of the original contract.

Such gains are being deferred and recognized over the remaining life of the contract on a straight line basis. During the three months ended March 31, 2013 and 2012, United accelerated the reclassification of $1,000 and $81,000, respectively, in gains from terminated positions as a result of the forecasted transactions becoming probable not to occur. During the next twelve months, United estimates that the remaining $365,000 of the deferred gains on terminated cash flow hedging positions will be reclassified as an increase to loan interest revenue. In addition, United’s forward starting active cash flow hedges of floating rate liabilities will begin to become effective over the next twelve months. United expects that $83,000 will be reclassified as an increase to deposit interest expense over the next twelve months related to these cash flow hedges.

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 involve the receipt of fixed-rate or variable rate amounts from a counterparty in exchange for United making variable rate or fixed rate payments over the life of the agreements without the exchange of the underlying notional amount. 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 of interest rate risk. Two of the interest rate swaps outstanding at March 31, 2013 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 fixed rate 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. As of March 31, 2012, United had four interest rate swaps with an aggregate notional amount of $64.5 million that were designated as fair value hedges.

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 line item as the offsetting loss or gain on the related derivatives. During the three months ended March 31, 2013 and 2012, United recognized net losses of $86,000 and net gains of $34,000, respectively, related to ineffectiveness of the fair value hedging relationships. United also recognized a net reduction of interest expense of $1.06 million and $278,000 for the three months ended March 31, 2013 and 2012, respectively, related to United’s fair value hedges of brokered time deposits, which includes net settlements on the derivatives. United recognized a $12,000 reduction of interest revenue on securities during the first quarter of 2013 related to United’s fair value hedges of corporate bonds.

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, 2013, collateral totaling $14.6 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.

Change in Valuation Methodology

As of January 1, 2013, United changed its valuation methodology for over-the-counter derivatives to discount cash flows based on Overnight Index Swap (“OIS”) rates. Fully collateralized trades are discounted using OIS with no additional economic adjustments to arrive at fair value. Uncollateralized or partially collateralized trades are also discounted at OIS, but include appropriate economic adjustments for funding costs (i.e. LIBOR-OIS basis adjustment to approximate uncollateralized cost of funds) and credit risk. United changed its methodology to better align its inputs, assumptions and pricing methodologies with those used in its principal market by most dealers and major market participants. The changes in valuation methodology are applied prospectively as a change in accounting estimate and are not material to United’s financial position or results of operations.

Stock-Based Compensation

3 Months Ended

Mar. 31, 2013

Disclosure Of Compensation Related Costs, Share-Based Payments [Abstract]

Stock-Based Compensation

Note 10 – Stock-Based Compensation

United has an equity compensation plan that allows for grants of incentive stock options, nonqualified stock options, restricted stock and restricted stock unit awards (also referred to as “nonvested stock” awards), stock awards, performance share awards or stock appreciation rights. Options granted under the plan can have an exercise price no less than the fair market value of the underlying stock at the date of grant. The general terms of the plan include a vesting period (usually four years) with an exercisable period not to exceed ten years. Certain option and 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, 2013, 1,194,000 additional awards could be granted under the plan. Through March 31, 2013, 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 2013.

						Weighted-
						Average		Aggregate
				Weighted-		Remaining		Intrinisic
				Average Exercise		Contractual		Value
Options	Shares			Price		Term (Years)		($000)

Outstanding at December 31, 2012		482,528		$	97.73
Forfeited		(859	)		30.11
Expired		(5,358	)		98.55
Outstanding at March 31, 2013		476,311			97.85		3.1	$	1

Exercisable at March 31, 2013		456,514			101.07		2.9		—

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 three month period ended March 31, 2013. Recent decreases in United’s stock price have rendered most of its 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. No options were granted during the three months ended March 31, 2013 and 2012.

Compensation expense relating to stock options of $64,000 and $180,000 was included in earnings for the three months ended March 31, 2013 and 2012, respectively. The amount of compensation expense for both periods was determined based on the fair value of the options at the time of grant, multiplied by the number of options granted that are expected to vest, which was then amortized over the vesting period. The forfeiture rate for options is estimated to be approximately 3% per year. No options were exercised during the first three months of 2013 or 2012.

The table below presents the activity in restricted stock and restricted stock unit awards for the first three months of 2013.

				Weighted-
				Average Grant-
Restricted Stock	Shares			Date Fair Value

Outstanding at December 31, 2012		485,584		$	10.72
Granted		21,517			10.26
Excercised		(4,301	)		14.03
Cancelled		(5,000	)		10.25
Outstanding at March 31, 2013		497,800			10.68

Vested at March 31, 2013		43,100			21.98

Compensation expense for restricted stock and restricted stock units is based on the fair value of restricted stock and restricted stock unit awards at the time of grant, which is equal to the value of United’s common stock on the date of grant. The value of restricted stock and restricted stock unit grants that are expected to vest is amortized into expense over the vesting period. For the three months ended March 31, 2013 and 2012, compensation expense of $445,000 and $405,000, respectively, was recognized related to restricted stock and restricted stock unit awards. In addition, for the three months ended March 31, 2013, $17,000 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 and restricted stock units was $5.65 million at March 31, 2013.

As of March 31, 2013, there was $2.85 million of unrecognized compensation cost related to non-vested stock options and restricted stock and restricted stock unit awards granted under the plan. That cost is expected to be recognized over a weighted-average period of 1.76 years. The aggregate grant date fair value of options and restricted stock and restricted stock unit awards that vested during the three months ended March 31, 2013, was $461,000.

Common and Preferred Stock Issued / Common Stock Issuable	3 Months Ended
	Mar. 31, 2013
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 the Company. 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. 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 (“ESPP”) 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, 2013 and 2012, United issued 18,170 and 35,648 shares, respectively, and increased capital by $189,000 and $278,000, respectively, through these programs. United offers its common stock as an investment option in its deferred compensation plan. 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, 2013 and 2012, 133,469 and 90,126 shares, respectively, were issuable under the deferred compensation plan.

Assets and Liabilities Measured at Fair Value

3 Months Ended

Mar. 31, 2013

Fair Value [Abstract]

Assets and Liabilities Measured at Fair Value

Note 12 – Assets and Liabilities Measured at Fair Value

Fair value measurements are determined based on the assumptions that market participants would use in pricing the asset or liability. As a basis for considering market participant assumptions in fair value measurements, the Financial Accounting Standards Board’s Accounting Standards Codification Topic 820 (“ASC 820”) Fair Value Measurements and Disclosures establishes 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 and corporate debt securities. Securities classified as Level 3 include asset-backed securities in less liquid markets.

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. Generally, book value approximates fair value.

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, 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.

Goodwill and Other Intangible Assets

Goodwill and identified intangible assets are subject to impairment testing. United’s approach to testing goodwill for impairment is to compare the business unit’s carrying value to the implied fair value based on multiples of earnings and tangible book value for recently completed merger transactions. In the event the fair value is determined to be less than the carrying value, the asset is recorded at fair value as determined by the valuation model. As such, United classifies goodwill and other intangible assets subjected to nonrecurring fair value adjustments as 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 March 31, 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.

United has 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, 2013, December 31, 2012 and March 31, 2012, 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 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) 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, 2013, December 31, 2012, and March 31, 2012 are as follows (in thousands).

Commitments and Contingencies Disclosure [Abstract]

Commitments and Contingencies

Note 13 – Commitments and Contingencies

United and its wholly-owned subsidiary, United Community Bank, (“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, 2013, December 31, 2012 and March 31, 2012, the contractual amount of off-balance sheet instruments (in thousands):

Financial instruments whose contract amounts represent credit risk:		March 31, 2013		December 31, 2012		March 31, 2012
	Commitments to extend credit	$	565,685	$	313,798	$	429,672
	Letters of credit		12,818		13,683		16,655

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.

Accounting Policies (Policies)	3 Months Ended
Accounting Policies (Policies)	Mar. 31, 2013
Summary Of Significant Accounting Policies [Abstract]
Real Estate Sales	Foreclosed property is initially recorded at fair value, less the estimated cost to sell. If the fair value less the estimated cost 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 fair value less the estimated cost to sell of the foreclosed property decreases during the holding period, a valuation allowance is established with a charge to operating expenses. 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 the Financial Accounting Standards Board’s (“FASB”) Accounting Standards Codification (“ASC”) 360-20, Real Estate Sales.
Master Netting Agreements	United enters into reverse repurchase agreements in order to invest short-term funds. In addition, United enters into repurchase agreements and reverse repurchase agreements with the same counterparty in transactions commonly referred to as collateral swaps that are subject to master netting agreements under which the balances are netted in the balance sheet in accordance with ASC 210-20, Offsetting.
Clarifying the Scope of Disclosures about Offsetting Assets and Liabilities	In January 2013, the FASB issued Accounting Standards Update No. 2013-01, Clarifying the Scope of Disclosures about Offsetting Assets and Liabilities. This ASU limits the scope of the new balance sheet offsetting disclosures to derivatives, repurchase agreements, and securities lending transactions to the extent that they are (1) offset in the financial statements or (2) subject to an enforceable master netting agreement. The disclosure requirements were effective for annual reporting periods beginning on or after January 1, 2013 and interim periods within those annual periods. It did not have a material impact on United’s financial position or results of operations, and resulted in additional disclosures.
Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income	In February 2013, the FASB issued Accounting Standards Update No. 2013-02, Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income. The amendments in this update require an entity to provide information about the amounts reclassified out of accumulated other comprehensive income by component and by the respective line items of net income. The standard was effective for fiscal years, and interim periods within those years, beginning after December 15, 2012. This guidance did not have a material impact on United’s financial position or results of operations, and resulted in additional disclosures.

- Definition

Tabular disclosure of the fair value measurement of assets using significant unobservable inputs (Level 3), a reconciliation of the beginning and ending balances, separately presenting changes during the period attributable to the following: (1) total gains or losses for the period (realized and unrealized), segregating those gains or losses included in earnings (or changes in net assets) and gains or losses recognized in other comprehensive income (loss), and a description of where those gains or losses included in earnings (or changes in net assets) are reported in the statement of income (or activities); (2) purchases, sales, issues, and settlements (each type disclosed separately); and (3) transfers in and transfers out of Level 3 (for example, transfers due to changes in the observability of significant inputs), by class of asset.
