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, 2011.

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 estimated costs to sell. If the fair value, less estimated costs to sell at the time of foreclosure, is less than the loan balance, the deficiency is charged against the allowance for loan losses. If the fair value, less 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.

In July 2012, the Financial Accounting Standards Board issued Accounting Standards Update No. 2012-02, Testing Indefinite-Lived Intangible Assets for Impairment (the revised standard). It allows companies to perform a “qualitative” assessment to determine whether further impairment testing of indefinite-lived intangible assets is necessary, similar in approach to the goodwill impairment test. The revised standard is effective for annual and interim impairment tests performed for fiscal years beginning after September 15, 2012, and entities can choose to early adopt the revised guidance. It is not expected to have a material impact on United’s financial position, results of operations or disclosures.

- 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.

Mergers and Acquisitions

Note 3 – Mergers and Acquisitions

On June 19, 2009, United Community Bank (“UCB” or the “Bank”) purchased substantially all the assets and assumed substantially all the liabilities of Southern Community Bank (“SCB”) from the Federal Deposit Insurance Corporation (“FDIC”), as Receiver of SCB. UCB and the FDIC entered loss sharing agreements regarding future losses incurred on loans and foreclosed loan collateral existing at June 19, 2009. Under the terms of the loss sharing agreements, the FDIC will absorb 80 percent of losses and share 80 percent of loss recoveries on the first $109 million of losses and, absorb 95 percent of losses and share in 95 percent of loss recoveries on losses exceeding $109 million. The term for loss sharing on 1-4 Family loans is ten years, while the term for loss sharing on all other loans is five years.

Under the loss sharing agreement, the portion of the losses expected to be indemnified by the FDIC is considered an indemnification asset in accordance with ASC 805 Business Combinations. The indemnification asset, referred to as “estimated loss reimbursement from the FDIC,” is included in the balance of “Assets covered by loss sharing agreements with the FDIC” on the Consolidated Balance Sheet. The indemnification asset was recognized at fair value, which was estimated at the acquisition date based on the terms of the loss sharing agreement. The indemnification asset is expected to be collected over a four-year average life. No valuation allowance was required.

Loans, foreclosed property and the estimated FDIC reimbursement resulting from the loss sharing agreements with the FDIC are reported as “Assets covered by loss sharing agreements with the FDIC” in the consolidated balance sheet.

The table below shows the components of covered assets at June 30, 2012 (in thousands).

At June 30, 2012, there were 36 available for sale securities and no 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 June 30, 2012 were primarily attributable to changes in interest rates, however the unrealized losses in corporate bonds also reflect downgrades in the underlying securities ratings. The bonds remain above investment grade and United does not consider them to be impaired. Unrealized losses at June 30, 2011 were primarily attributable to changes in interest rates.

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 analyst’s reports. No impairment charges were recognized during the second quarter or six months ended June 30, 2012 or 2011.

The amortized cost and fair value of held to maturity and available for sale securities at June 30, 2012, by contractual maturity, are presented in the following table (in thousands).

In calculating specific reserves, United reviews all loans that are on nonaccrual with a balance of $500,000 or greater for impairment, as well as accruing substandard relationships greater than $2 million and all troubled debt restructurings (“TDRs”). 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 troubled debt restructurings are considered impaired regardless of accrual status. Impaired loans are measured based on the present value of expected future cash flows, discounted at the loan’s effective interest rate, at the loan’s observable market price, or the fair value of the collateral if the loan is collateral dependent. 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.

At June 30, 2012, December 31, 2011 and June 30, 2011, loans with a carrying value of $1.61 billion, $1.52 billion and $991 million were pledged as collateral to secure FHLB advances and other contingent funding sources.

In the first quarter of 2011, United’s Board of Directors adopted an accelerated problem asset disposition plan which included the bulk sale of $267 million in classified loans. Those loans were classified as held for sale at the end of the first quarter and were written down to the expected proceeds from the sale. The charge-offs on the loans transferred to held for sale in anticipation of the bulk loan sale which closed on April 18, 2011, increased first quarter 2011 loan charge-offs by $186 million. The actual loss on the bulk loan sale at closing was less than the amount charged-off in the first quarter, resulting in a $7.27 million reduction of second quarter 2011 charge-offs.

The recorded investments in individually evaluated impaired loans at June 30, 2012, December 31, 2011 and June 30, 2011 were as follows (in thousands).

As of June 30, 2012 and December 31, 2011, $10.3 million and $8.65 million of specific reserves were allocated to customers whose loan terms have been modified in troubled debt restructurings. There were no specific reserves established for loans considered to be troubled debt restructurings at June 30, 2011. United committed to lend additional amounts totaling up to $490,000, $1.12 million, and $396,000 as of June 30, 2012 and December 31, 2011, and June 30, 2011 respectively, to customers with outstanding loans that are classified as TDRs.

The modification of the terms of the troubled debt restructurings included one or a combination of the following: a reduction of the stated interest rate of the loan; an extension of the maturity date or an extension of the amortization period, any of which are not available in the current market for new debt with similar risk; a permanent reduction of the principal amount; or a restructuring of the borrower’s debt into an A/B note structure.

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, 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 the Company 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 June 30, 2012, December 31, 2011 and June 30, 2011, and based on the most recent analysis performed, the risk category of loans by class of loans is as follows (in thousands).

Earnings Per Share

Note 8 – Earnings Per Share

United is required to report on the face of the consolidated statement of operations, earnings (loss) 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 (loss) 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 and six months ended June 30, 2012 and 2011, United accrued dividends on preferred stock, including accretion of discounts, as shown in the following table (in thousands).

Total preferred stock dividends	$	3,032	$	3,016	$	6,062	$	5,794

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 (loss) in order to arrive at net income (loss) available to common shareholders. There is no dilution from potentially dilutive securities for the six months ended June 30, 2011, due to the anti-dilutive effect of the net loss for that period.

The following table sets forth the computation of basic and diluted loss per share for the three and six months ended June 30, 2012 and 2011 (in thousands, except per share data).

Derivatives and Hedging Activities [Abstract]

Derivatives and Hedging Activities

Note 9 – Derivatives and Hedging Activities

Risk Management Objective of Using Derivatives

United is exposed to certain risks arising from both its business operations and economic conditions. United principally manages its exposures to a wide variety of business and operational risks through management of its core business activities. United manages interest rate risk primarily by managing the amount, sources, and duration of its investment securities portfolio and debt 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 June 30, 2012, December 31, 2011 and June 30, 2011 (in thousands).

Derivatives accounted for as hedges under ASC 815


		Fair Value

Asset derivatives	Other assets	$	68	$	—	$	—

Asset derivatives	Other assets	$	155	$	—	$	—

Liability derivatives	Other liabilities	$	155	$	—	$	—

Derivative contracts that are not accounted for as hedges under ASC 815 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 June 30, 2012, 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 the company in a rising rate environment. The swaps are forward starting and do not become effective until 2014. At June 30, 2012, United had five swap contracts outstanding with a total notional amount of $400 million that were designated as cash flow hedges. United had no active derivative contracts outstanding at December 31, 2011 or June 30, 2011 that were designated as cash flow hedges of interest rate risk.

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 in 2014 as interest payments are made on United’s LIBOR based variable-rate wholesale borrowings and indexed deposit accounts. At June 30, 2012, 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 and six months ended June 30, 2012, United accelerated the reclassification of $43,000 and $124,000, 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 an additional $2.23 million of the deferred gains on terminated cash flow hedging positions will be reclassified as an increase to interest revenue.

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 LIBOR, a benchmark interest rate. United uses interest rate swaps to manage its exposure to changes in fair value on these instruments attributable to changes in the benchmark interest rate. Interest rate swaps designated as fair value hedges 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. At June 30, 2012, United had seven interest rate swaps with an aggregate notional amount of $104 million that were designated as fair value hedges of interest rate risk. As of June 30, 2011, United had no active derivatives designated as fair value hedges of interest rate risk.

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 and six months ended June 30, 2012, United recognized net losses of $223,000 and $189,000, respectively, related to ineffectiveness of the fair value hedging relationships. United also recognized a net reduction of interest expense of $550,000 and $828,000 for the three and six months ended June 30, 2012, related to United’s fair value hedges, which includes net settlements on the derivatives. There were no active fair value hedges during the first six months of 2011.

Credit-risk-related Contingent Features

United manages its credit exposure on derivatives transactions by entering into a bi-lateral 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.

United’s agreements with each of its derivative counterparties contain a provision where if either party defaults on any of its indebtedness, then it could also be declared in default on its derivative obligations. The agreements with derivatives counterparties also include provisions that if not met, could result in United being declared in default. United has agreements with certain of its derivative counterparties that contain a provision where if United fails to maintain its status as a well-capitalized institution or is subject to a prompt corrective action directive, the counterparty could terminate the derivative positions and United would be required to settle its obligations under the agreements.

Stock-Based Compensation

6 Months Ended

Jun. 30, 2012

Stock-Based Compensation [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 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 awards provide for accelerated vesting if there is a change in control (as defined in the plan). As of June 30, 2012, 1,351,000 additional awards could be granted under the plan. Through June 30, 2012, incentive stock options, nonqualified stock options, restricted stock awards and units and base salary stock grants had been granted under the plan.

The following table shows stock option activity for the first six months of 2012.


Options	Shares			Weighted- Average Exercise Price		Weighted- Average Remaining Contractual Term (Years)		Aggregate Intrinisic Value ($000)
Outstanding at December 31, 2011		583,647		$	94.48
Forfeited		(2,472	)		48.22
Expired		(78,432	)		73.89

Outstanding at June 30, 2012		502,743			97.92		4.0	$	—

Exercisable at June 30, 2012		478,452			101.71		3.8		—

The fair value of each option is estimated on the date of grant using the Black-Scholes model. No stock options were granted during the six month periods ended June 30, 2012 or 2011.

Compensation expense relating to stock options of $131,000 and $465,000 was included in earnings for the six months ended June 30, 2012 and 2011, respectively. Deferred tax benefits of $50,000 and $181,000, respectively, were included in the determination of income tax expense for the six month periods ended June 30, 2012 and 2011. 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 six months of 2012 or 2011.

The table below presents the activity in restricted stock awards for the first six months of 2012.


Restricted Stock	Shares			Weighted- Average Grant- Date Fair Value
Outstanding at December 31, 2011		414,644		$	12.19
Granted		29,491			9.36
Excercised		(18,690	)		39.13
Cancelled		(11,400	)		10.25

Outstanding at June 30, 2012		414,045			11.43

Vested at June 30, 2012		15,490			35.62

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 six months ended June 30, 2012 and 2011, compensation expense of $815,000 and $293,000, respectively, was recognized related to restricted stock awards. The total intrinsic value of the restricted stock was $3.55 million at June 30, 2012.

As of June 30, 2012, there was $3.10 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 1.93 years. The aggregate grant date fair value of options and restricted stock awards that vested during the six months ended June 30, 2012, was $1.54 million.

Common and Preferred Stock Issued / Common Stock Issuable And Reclassifications and Reverse Stock Split [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 six months ended June 30, 2012 and 2011, United issued 60,982 and 78,584 shares, respectively, and increased capital by $501,000 and $744,000, 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 June 30, 2012 and 2011, 94,657 and 83,575 shares, respectively, were issuable under the deferred compensation plan.

On February 22, 2011, United entered into a Share Exchange Agreement with the Elm Ridge Parties. Under the Share Exchange Agreement, the Elm Ridge Parties agreed to transfer to United 1,551,126 shares of United’s common stock in exchange for 16,613 shares of United’s cumulative perpetual preferred stock, Series D, and warrants to purchase 1,551,126 common shares with an exercise price of $12.50 per share that expires on August 22, 2013. This exchange transaction did not result in a net increase or decrease to total shareholder’s equity for the year ended December 31, 2011.

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 June 30, 2012, December 31, 2011 and June 30, 2011, aggregated by the level in the fair value hierarchy within which those measurements fall (in thousands).

Assets and Liabilities Not Measured at Fair Value

For financial instruments that have quoted market prices, those quotes are used to determine fair value. Financial instruments that have no defined maturity, have a remaining maturity of 180 days or less, or reprice frequently to a market rate, are assumed to have a fair value that approximates reported book value, after taking into consideration any applicable credit risk. If no market quotes are available, financial instruments are valued by discounting the expected cash flows using an estimated current market interest rate for the financial instrument. For off-balance sheet derivative instruments, fair value is estimated as the amount that United would receive or pay to terminate the contracts at the reporting date, taking into account the current unrealized gains or losses on open contracts.

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, federal funds purchased, repurchase agreements and other short-term borrowings. The fair value of securities available for sale equals the balance sheet 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 June 30, 2012, December 31, 2011, and June 30, 2011 are as follows (in thousands).

Reclassification and Reverse Stock Split

Note 13 – Reclassification and Reverse Stock Split

Certain 2011 amounts have been reclassified to conform to the 2012 presentation. On June 17, 2011, United completed a 1-for-5 reverse stock split, or recombination, whereby each five shares of United’s common stock was reclassified into one share of common stock and each five shares of United’s non-voting common stock was reclassified into one share of non-voting common stock. All share and per share amounts for all periods presented have been adjusted to reflect the reverse split as though it had occurred prior to the earliest period presented.

Accounting Policies (Policies)	6 Months Ended
Accounting Policies (Policies)	Jun. 30, 2012
Accounting Policies [Abstract]
Real Estate Sales	Foreclosed property is initially recorded at fair value, less estimated costs to sell. If the fair value, less estimated costs to sell at the time of foreclosure, is less than the loan balance, the deficiency is charged against the allowance for loan losses. If the fair value, less 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	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.
Testing Indefinite-Lived Intangible Assets for Impairment	In July 2012, the Financial Accounting Standards Board issued Accounting Standards Update No. 2012-02, Testing Indefinite-Lived Intangible Assets for Impairment (the revised standard). It allows companies to perform a “qualitative” assessment to determine whether further impairment testing of indefinite-lived intangible assets is necessary, similar in approach to the goodwill impairment test. The revised standard is effective for annual and interim impairment tests performed for fiscal years beginning after September 15, 2012, and entities can choose to early adopt the revised guidance. It is not expected to have a material impact on United’s financial position, results of operations or 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.
