	1. GENERAL
	The accompanying unaudited interim condensed consolidated financial statements include the accounts of United Security Bancshares, Inc. (“USBI”) and its subsidiaries (collectively, the “Company”). USBI is the parent holding company of First United Security Bank (the “Bank” or “FUSB”). The Bank operates a finance company, Acceptance Loan Company, Inc. (“ALC”). All significant intercompany transactions and accounts have been eliminated.
	The unaudited interim condensed consolidated financial statements, in the opinion of management, reflect all adjustments necessary for a fair presentation of consolidated financial position, results of operations and cash flows for the periods presented. Such adjustments are of a normal, recurring nature. The results of operations for any interim period are not necessarily indicative of results expected for the fiscal year ending December 31, 2014. While certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) have been condensed or omitted pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”), management believes that the disclosures herein are adequate to make the information presented not misleading. These unaudited interim condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto contained in USBI’s Annual Report on Form 10-K for the year ended December 31, 2013. The accounting policies followed by the Company are set forth in Note 2, “Summary of Significant Accounting Policies,” of the Notes to Consolidated Financial Statements in USBI’s Annual Report on Form 10-K for the year ended December 31, 2013. Certain amounts in the 2013 condensed consolidated financial statements have been reclassified to conform to the 2014 method of presentation.

Recent Accounting Pronouncements	'
	2. RECENT ACCOUNTING PRONOUNCEMENTS
	In January 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-04, Receivables – Troubled Debt Restructurings by Creditors (Subtopic 310-40): Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure (a consensus of the FASB Emerging Issues Task Force). ASU 2014-04 clarifies when an “in substance repossession or foreclosure” occurs, that is, when a creditor should be considered to have received physical possession of residential real estate property collateralizing a consumer mortgage loan, such that all or a portion of the loan should be derecognized and the real estate property recognized. ASU 2014-04 states that a creditor is considered to have received physical possession of residential real estate property collateralizing a consumer mortgage loan, upon either the creditor obtaining legal title to the residential real estate property upon completion of a foreclosure, or the borrower conveying all interest in the residential real estate property to the creditor to satisfy that loan through completion of a deed in lieu of foreclosure or through a similar legal agreement. The amendments of ASU 2014-04 also require interim and annual disclosure of both the amount of foreclosed residential real estate property held by the creditor and the recorded investment in consumer mortgage loans collateralized by residential real estate properties that are in the process of foreclosure. The amendments of ASU 2014-04 are effective for interim and annual periods beginning after December 15, 2014 and may be applied using either a modified retrospective transition method or a prospective transition method as described in ASU 2014-04. The adoption of ASU 2014-04 is not expected to have a significant impact on the Company’s consolidated financial position, results of operations or cash flows.
	In January 2014, the FASB issued ASU 2014-01, Investments – Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Qualified Affordable Housing Projects (a consensus of the FASB Emerging Issues Task Force). ASU 2014-01 permits reporting entities that invest in qualified affordable housing projects to elect to account for those investments using the “proportional amortization method” if certain conditions are met. Under this method, an entity amortizes the initial cost of the investment in proportion to the tax credits and other tax benefits received and recognizes the net investment performance in the income statement as a component of income tax expense (benefit). The decision to apply the proportional amortization method of accounting is an accounting policy decision and should be applied consistently to all qualifying affordable housing project investments. ASU 2014-01 should be applied retrospectively to all periods presented and is effective for annual and interim reporting periods beginning after December 15, 2014. The Company does not have a significant amount of investments in qualified affordable housing projects that qualify for the low income housing tax credit. Such investments are currently either consolidated in the Company’s financial statements or accounted for as cost method investments. The adoption of ASU 2014-01 is not expected to have a significant impact on the Company’s consolidated financial position, results of operations or cash flows.
	In July 2013, the FASB issued ASU 2013-11, Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists (a consensus of the FASB Emerging Issues Task Force). ASU 2013-11 provides that an entity’s unrecognized tax benefit, or a portion of its unrecognized tax benefit, should be presented in its financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward, with one exception. The exception states that to the extent a net operating loss carryforward, a similar tax loss, or a tax credit carryforward is not available at the reporting date under the tax law of the applicable jurisdiction to settle any additional income taxes that would result from the disallowance of a tax position, or the tax law of the applicable jurisdiction does not require the entity to use, and the entity does not intend to use, the deferred tax asset for such purpose, the unrecognized tax benefit should be presented in the financial statements as a liability and should not be combined with deferred tax assets. ASU 2013-11 applies prospectively for all entities that have unrecognized tax benefits when a net operating loss carryforward, a similar tax loss, or tax credit carryforward exists at the reporting date. ASU 2013-11 is effective for fiscal years, and interim periods within those years beginning after December 15, 2013. The Company adopted ASU 2013-11 on January 1, 2014. The adoption of ASU 2013-11 did not have a significant impact on the Company’s consolidated financial position, results of operations or cash flows.

	3. NET INCOME PER SHARE
	Basic net income per share is computed by dividing net income by the weighted average shares during the three-month periods ended March 31, 2014 and 2013. Diluted net income per share for the three-month periods ended March 31, 2014 and 2013 is computed based on the weighted average shares outstanding during the period plus the dilutive effect of all potentially dilutive instruments outstanding. In March 2014, the Company granted 10,750 nonqualified stock options to employees with a grant date fair value of $39,000. The options are exercisable upon completion of one year of service from the date of grant. Compensation expense associated with the grant totaled approximately $1,000 for the quarter ended March 31, 2014. All of the options remained outstanding as of March 31, 2014, and were considered potentially dilutive; however, net income per share was the same under both the basic and diluted calculations as of March 31, 2014. There were no outstanding potentially dilutive instruments impacting net income per share as of March 31, 2013.
	The following table represents the basic and diluted net income per share calculations for the three-month periods ended March 31, 2014 and 2013:

Comprehensive Income	'
	4. COMPREHENSIVE INCOME
	Comprehensive income consists of net income and the change in the unrealized gains or losses on the Company’s available-for-sale securities portfolio arising during the period. In the calculation of comprehensive income, certain reclassification adjustments are made for any sale of investment securities to avoid double counting items that are displayed as part of net income for a period that also had been displayed as part of other comprehensive income in that period or earlier periods.

Fair Value Disclosures [Abstract]	'
Fair Value of Financial Instruments	'
	5. FAIR VALUE OF FINANCIAL INSTRUMENTS
	The Company follows the provisions of ASC Topic 820, Fair Value Measurements and Disclosures, which defines fair value, establishes a framework for measuring fair value and expands disclosures about fair value measurements.
	Fair Value Hierarchy
	The assumptions used in the estimation of the fair value of the Company’s financial instruments are detailed below. Where quoted prices are not available, fair values are based on estimates using discounted cash flows and other valuation techniques. The use of discounted cash flows can be significantly affected by the assumptions used, including the discount rate and estimates of future cash flows. The following disclosures should not be considered a surrogate of the liquidation value of the Company, but rather represent a good-faith estimate of the increase or decrease in value of financial instruments held by the Company since purchase, origination or issuance.
	Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between willing market participants at the measurement date. In determining fair value, the Company uses various methods, including market, income and cost approaches. Based on these approaches, the Company often utilizes certain assumptions that market participants would use in pricing the asset or liability, including assumptions about risk and/or the risks inherent in the inputs to the valuation technique. These inputs can be readily observable, market corroborated or generally unobservable inputs. The Company utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs. Based on the observability of the inputs used in the valuation techniques, the Company is required to provide the following information according to the fair value hierarchy. The fair value hierarchy ranks the quality and reliability of the information used to determine fair values. Assets and liabilities carried at fair value will be classified and disclosed in one of the following three categories:
		•		Level 1 — Valuations for assets and liabilities traded in active exchange markets, such as the New York Stock Exchange or NASDAQ. Valuations are obtained from readily available pricing sources for market transactions involving identical assets or liabilities.
		•		Level 2 — Valuations for assets and liabilities traded in less active dealer or broker markets. Valuations are obtained from third-party pricing services for identical or similar assets or liabilities.
		•		Level 3 — Valuations for assets and liabilities that are derived from other valuation methodologies, including option pricing models, discounted cash flow models and similar techniques, and not based on market exchange, dealer or broker-traded transactions. Level 3 valuations incorporate certain assumptions and projections in determining the fair value assigned to such assets or liabilities.
	The Company rarely transfers assets and liabilities measured at fair value between Level 1 and Level 2 measurements. Trading account assets and securities available-for-sale may be periodically transferred to or from Level 3 valuation based on management’s conclusion regarding the best method of pricing for an individual security. Such transfers are accounted for as if they occurred at the beginning of a reporting period. There were no such transfers during the periods ended March 31, 2014 or December 21, 2013.
	Fair Value Measurements on a Recurring Basis
	Available-for-Sale Securities
	Where quoted market prices are available in an active market, securities are classified within Level 1 of the valuation hierarchy. Level 1 securities would include exchange traded equities. Level 2 securities include U.S. treasury and agency securities, mortgage-backed agency securities, obligations of states and political subdivisions and certain corporate, asset-backed and other securities. Level 2 fair values are obtained from quoted prices of securities with similar characteristics. In certain cases, where Level 1 or Level 2 inputs are not available, securities are classified within Level 3 of the hierarchy.
	The following table presents the balances of available-for-sale securities measured at fair value on a recurring basis as of March 31, 2014 and December 31, 2013.

	Fair Value Measurements on a Non-recurring Basis
	Impaired Loans
	Estimates of fair value for impaired loans are determined based on a variety of information, including the use of available appraisals, estimates of market value by licensed appraisers or local real estate brokers and the knowledge and experience of the Company’s management related to the assessment of collateral associated with loans. Management takes into consideration the type, location and occupancy of the collateral, as well as current economic conditions in the area in which the collateral is located, in assessing estimates of fair value.
	Loan impairment is reported when full payment under the loan terms is not expected. Impaired loans are carried at the present value of estimated future cash flows using the loan’s existing rate or the fair value of collateral if the loan is collateral dependent. A portion of the allowance for loan losses is allocated to impaired loans if the value of such loans is deemed to be less than the unpaid balance. If these allocations cause the allowance for loan losses to increase, such increase is reported as a component of the provision for loan losses. When an impaired loan is determined to be collateral dependent, the fair value is determined through the utilization of a third-party appraisal. It is the policy of the Company to update appraisals every 18-24 months. The types of collateral influence the frequency of obtaining updated appraisals. Management knows the market trends of collateral values well and monitors trends in sales and valuations in all of the various categories of collateral. These trends influence how often new appraisals are obtained within the 18-24 month timeframe. An example would be loans collateralized by residential subdivision lots. The values of this type of collateral have been volatile in recent years, and, therefore, appraisals are generally updated at the lower end of the timeframe (i.e., closer to 18 months), while timberland appraisals, which have been less volatile in recent years, would be updated closer to the upper end of the timeframe (i.e., closer to 24 months). Any observed trend indicating significant changes in valuations would require updated appraisals. Based on experience, current appraisals are discounted 9% for estimated costs associated with foreclosures and costs to sell. If a loan is evaluated for impairment under ASC Topic 310-10-35, Accounting by Creditors for Impairment of a Loan, and the appraisal is outdated, a new appraisal is ordered. If the new appraisal is not received in sufficient time to assess any required impairment to meet financial reporting obligations, the old appraisal may be adjusted to reflect values observed in similar properties. After a new appraisal is obtained, the analysis is updated to reflect the new valuation. Loan losses are charged against the allowance when management believes that the uncollectability of a loan is confirmed. Loans, net of specific allowances for fair-value impairment, amounted to $3.4 million and $11.4 million as of March 31, 2014 and December 31, 2013, respectively. This valuation was derived using Level 3 inputs, consisting of appraisals of underlying collateral and discounted cash flow analysis.
	Foreclosed Assets
	Estimates of fair values for foreclosed assets are determined based on a variety of information, including the use of available appraisals, estimates of market value by licensed appraisers or local real estate brokers and the knowledge and experience of the Company’s management related to the assessment of the values of foreclosed properties. Management takes into consideration the type, location and occupancy of the property, as well as current economic conditions in the area in which the property is located, in assessing estimates of fair value.
	The fair value of a foreclosed asset, upon initial recognition, is estimated using Level 2 inputs based on observable market data or Level 3 inputs based on customized discounting criteria and/or market data. Foreclosed assets measured at fair value upon initial recognition totaled $0.1 million and $0.5 million (utilizing Level 3 valuation inputs) as of March 31, 2014 and December 31, 2013, respectively. In connection with the measurement and initial recognition of the foregoing foreclosed assets, the Company recognized charge-offs of the allowance for loan losses totaling approximately zero and $0.3 million as of March 31, 2014 and March 31, 2013, respectively. Other foreclosed assets totaling $2.1 million and $5.3 million (utilizing Level 3 valuation inputs) were remeasured at fair value as of March 31, 2014 and December 31, 2013, respectively. The remeasurement resulted in no impairment of other real estate owned as of March 31, 2014, and impairment of $1.3 million as of December 31, 2013.
	The following table presents the balances of impaired loans and foreclosed assets measured at fair value on a non-recurring basis as of March 31, 2014 and December 31, 2013.

Impaired loans
Impaired loans are valued based on multiple data points indicating the fair value for each loan. The primary data point for non-performing loans is the appraisal value of the underlying collateral to which a discount is applied. Management establishes this discount or comparability adjustment based on recent sales of similar property types. As liquidity in the market increases or decreases, the comparability adjustment and the resulting asset valuation are impacted.
Foreclosed property and other real estate
Foreclosed property and other real estate under a binding contract for sale are valued based on contract price. If no sales contract is pending for a specific property, management establishes a comparability adjustment to the appraised value based on historical activity considering proceeds for properties sold versus the corresponding appraised value. Increases or decreases in realization for properties sold impact the comparability adjustment for similar assets remaining on the balance sheet.
Fair Value of Financial Instruments
ASC Topic 825, Financial Instruments, requires disclosure of fair value information about financial instruments, whether or not recognized on the face of the balance sheet, for which it is practicable to estimate that value. The following methods and assumptions were used by the Company in estimating the fair value of its financial instruments:
Cash, due from banks and federal funds sold: The carrying amount of cash, due from banks and federal funds sold approximates fair value.
Federal Home Loan Bank (“FHLB”): Based on the redemption provision of the FHLB, the stock has no quoted market value and is carried at cost.
Securities: Fair values of securities are based on quoted market prices where available. If quoted market prices are not available, estimated fair values are based on market prices of comparable instruments.
Accrued interest receivable and payable: The carrying amount of accrued interest approximates fair value.
Loans, net: For variable-rate loans, fair values are based on carrying values. Fixed-rate commercial loans, other installment loans and certain real estate mortgage loans are valued using discounted cash flows. The discount rate used to determine the present value of these loans is based on interest rates currently being charged by the Company on comparable loans as to credit risk and term.
Demand and savings deposits: The fair values of demand deposits are equal to the carrying value of such deposits. Demand deposits include non-interest bearing demand deposits, savings accounts, NOW accounts and money market demand accounts.
Time deposits: The fair values of relatively short-term time deposits are equal to their carrying values. Discounted cash flows are used to value long-term time deposits. The discount rate used is based on interest rates currently being offered by the Company on comparable deposits as to amount and term.
Short-term borrowings: These borrowings may consist of federal funds purchased, securities sold under agreements to repurchase and the floating rate borrowings from the FHLB account. Due to the short-term nature of these borrowings, fair values approximate carrying values.
Long-term debt: The fair value of this debt is estimated using discounted cash flows based on the Company’s current incremental borrowing rate for similar types of borrowing arrangements as of March 31, 2014 and December 31, 2013.
Off-balance sheet instruments: The carrying amount of commitments to extend credit and standby letters of credit approximates fair value. The carrying amount of the off-balance sheet financial instruments is based on fees currently charged to enter into such agreements.
The estimated fair value and related carrying or notional amounts, as well as the level within the fair value hierarchy, of the Company’s financial instruments as of March 31, 2014 and December 31, 2013, are as follows:

	For purposes of the maturity table, mortgage-backed securities, which are not due at a single maturity date, have been allocated over maturity groupings based on the weighted-average contractual maturities of underlying collateral. The mortgage-backed securities generally mature earlier than their weighted-average contractual maturities because of principal prepayments.
	Management evaluates securities for other-than-temporary impairment no less frequently than quarterly and more frequently when economic or market concerns warrant such evaluation. Consideration is given to (1) the length of time and the extent to which fair value has been less than cost, (2) the financial condition and near-term prospects of the issuer and (3) whether the Company does not intend to sell these securities, and it is not more likely than not that the Company will be required to sell the securities before recovery of their amortized cost bases. At March 31, 2014 and December 31, 2013, based on the aforementioned considerations, management did not record an other-than-temporary impairment on any security that was in an unrealized loss position.
	The following table reflects the Company’s investments’ gross unrealized losses and fair value, aggregated by investment category and length of time that individual securities have been in a continuous unrealized loss position, at March 31, 2014 and December 31, 2013.

As of March 31, 2014, one debt security had been in a loss position for more than twelve months, and forty debt securities had been in a loss position for less than twelve months. The losses for all securities are considered to be a direct result of the effect that the current interest rate environment has on the value of debt securities and not related to the creditworthiness of the issuers. Further, the Company has the current intent and ability to retain its investments in the issuer for a period of time sufficient to allow for any anticipated recovery in fair value. Therefore, the Company has not recognized any other-than-temporary impairments.
Investment securities available-for-sale with a carrying value of $74.2 million and $72.7 million as of March 31, 2014 and December 31, 2013, respectively, were pledged to secure public deposits and for other purposes.
Gains realized on sales of securities available-for-sale were approximately $0.1 million and $0.5 million as of March 31, 2014 and December 31, 2013, respectively. The gains on sales as of December 31, 2013 resulted from a non-recurring fee received by the Bank in connection with the early payoff of a mortgage-backed pool. There were no losses on sales of securities as of both March 31, 2014 and December 31, 2013.

Investment in Limited Partnerships	'
	7. INVESTMENTS IN LIMITED PARTNERSHIPS
	The Company has investments in affordable housing projects for which it provides funding as a limited partner and receives tax credits related to its investments in the projects based on its partnership share. The Company’s investments include both direct investments and investments in funds that invest solely in affordable housing projects. The Company has determined that these structures require evaluation as a variable interest entity (“VIE”) under ASC Topic 810, Consolidation. The Company consolidates one of the funds in which it has a 99.9% limited partnership interest. Assets recorded by the Company as a result of the consolidation totaled approximately $53,000 as of both March 31, 2014 and December 31, 2013. The remaining limited partnership investments are unconsolidated and are accounted for under the cost method as allowed under ASC Topic 325, Accounting for Tax Benefits Resulting from Investments in Affordable Housing Projects. The Company amortizes the excess of carrying value of the investment over its estimated residual value during the period in which tax credits are allocated to the investors. The Company’s maximum exposure to future loss related to these limited partnerships was limited to the $0.8 million recorded investment as of both March 31, 2014 and December 31, 2013.
	The assets and liabilities of these partnerships consist primarily of apartment complexes and related mortgages. The Company’s carrying value approximates cost of its underlying equity in the net assets of the partnerships. Market quotations are not available for any of the aforementioned partnerships. Management has no knowledge of intervening events since the date of the partnerships’ financial statements that would have had a material effect on the Company’s consolidated financial position or results of operations.
	The Bank had no remaining cash commitments to these partnerships as of March 31, 2014 or December 31, 2013.

	The Company grants commercial, real estate and installment loans to its customers. Although the Company has a diversified loan portfolio, 73.3% and 69.2% of the portfolio was concentrated in loans secured by real estate located primarily within a single geographic region of the United States as of March 31, 2014 and December 31, 2013, respectively.
	Portfolio Segments:
	The Company has divided the loan portfolio into eight portfolio segments, each with different risk characteristics and methodologies for assessing the risk described as follows:
	Construction, land development and other land loans – Commercial construction, land and land development loans include the development of residential housing projects, loans for the development of commercial and industrial use property and loans for the purchase and improvement of raw land. These loans are secured in whole or in part by the underlying real estate collateral and are generally guaranteed by the principals of the borrowing entity.
	Secured by 1–4 family residential properties – These loans include conventional mortgage loans on one-to-four family residential properties. These properties may serve as the borrower’s primary residence, vacation home or investment property. Also included in this portfolio are home equity loans and lines of credit. This type of lending, which is secured by a first or second mortgage on the borrower’s residence, allows customers to borrow against the equity in their home.
	Secured by multi-family residential properties – These are mortgage loans secured by apartment buildings.
	Secured by non-farm, non-residential properties – Commercial real estate loans include loans secured by commercial and industrial properties, office or mixed-use facilities, strip shopping centers or other commercial property. These loans are generally guaranteed by the principals of the borrowing entity.
	Other real estate loans – Other real estate loans are loans primarily for agricultural production, secured by mortgages on farm land.
	Commercial and industrial loans – Includes loans to commercial customers for use in the normal course of business. These credits may be loans and lines to financially strong borrowers, secured by inventories, equipment or receivables, and are generally guaranteed by the principals of the borrowing entity.
	Consumer loans – Includes a variety of secured and unsecured personal loans, including automobile loans, loans for household and personal purposes and all other direct consumer installment loans.
	Other loans – Other loans comprise credit cards, overdrawn checking accounts reclassified to loans and overdraft lines of credit.
	Related Party Loans:
	In the ordinary course of business, the Bank makes loans to certain officers and directors of the Company, including companies with which they are associated. These loans are made on the same terms as those prevailing for comparable transactions with others. Management believes such loans do not represent more than normal risk of collectability, nor do they present other unfavorable features. The aggregate balances of such related party loans and commitments as of March 31, 2014 and December 31, 2013 were $3.4 million and $3.6 million, respectively. During the period ended March 31, 2014, there were no new loans to these parties, and repayments by active related parties were $0.2 million. During the year ended December 31, 2013, new loans to these related parties totaled $1.7 million, and repayments by active related parties were $0.6 million.
	Allowance for Loan Losses:
	The following tables present changes in the allowance for loan losses by reporting segment and loan type as of March 31, 2014 and December 31, 2013:

Credit Quality Indicators:
The Bank utilizes a model to evaluate the credit quality of its loan portfolio that includes categorizing loans into groupings by credit quality indicator. The model establishes a uniform framework and common language for assessing and monitoring risk in the portfolio. Under the model, loans have historically been categorized into one of eight risk grades which can be further summarized into categories described as pass, special mention, substandard, doubtful and loss, as described in further detail below. As of January 1, 2014, management established a nine-grade rating system, which had the effect of adding an additional risk grade to the pass category. The additional risk grade provides management with the ability to evaluate loans at a more granular level; however, it did not result in any change to the calculation of the allowance for loan losses as of either of the quarters ended March 31, 2014 or 2013, respectively, or the year ended December 31, 2013.
The following summarizes the credit quality indicators used in the nine-grade system:
	•		Pass (Risk Grades 1-5) – Loans in this category include obligations where the probability of default is considered low.
	•		Special Mention (Risk Grade 6): Borrowers in this category exhibit potential credit weaknesses or downward trends deserving Bank management’s close attention. If left uncorrected, these potential weaknesses may result in the deterioration of the repayment prospects for the asset or in the Bank’s credit position at some future date. Special mention loans are not adversely classified and do not expose the Bank to sufficient risk to warrant adverse classification. Although a special mention asset has a higher probability of default than pass rated categories, its default is not imminent.
	•		Substandard (Risk Grade 7): These are borrowers with defined weaknesses that jeopardize the orderly liquidation of debt. A substandard loan is inadequately protected by the current sound worth and paying capacity of the obligor or by the collateral pledged, if any. Normal repayment from the borrower is in jeopardy, although no loss of principal is envisioned. There is a distinct possibility that a partial loss of interest and/or principal will occur if the deficiencies are not corrected. Loss potential, while existing in the aggregate amount of substandard assets, does not have to exist in individual assets classified substandard.
	•		Doubtful (Risk Grade 8): Borrowers classified doubtful have all the weaknesses found in substandard borrowers with the added provision that the weaknesses make collection of debt in full, based on currently existing facts, conditions and values, highly questionable and improbable. Serious problems exist to the point where partial loss of principal is likely. The possibility of loss is extremely high, but because of certain important, reasonably specific pending factors that may work to strengthen the assets, the loans’ classification as estimated losses is deferred until a more exact status may be determined. Pending factors include proposed merger, acquisition or liquidation procedures, capital injection, perfecting liens on additional collateral and refinancing plans. Management of borrowers classified doubtful may have demonstrated a history of failing to live up to agreements.
	•		Loss (Risk Grade 9): Borrowers deemed incapable of repayment of unsecured debt. Loans to such borrowers are considered uncollectible and of such little value that continuance as active assets of the Bank is not warranted. This classification does not mean that the loan has absolutely no recovery or salvage value, but rather it is not prudent to defer writing off these worthless assets, even though partial recovery may be affected in the future.

Impaired Loans:
A loan is considered impaired when, based on current information and events, it is probable that the Company will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the related loan agreement. If a loan is impaired, a specific valuation allowance is allocated, if necessary, so that the loan is reported net, at the present value of estimated future cash flows using the loan’s existing rate or at the fair value of collateral if repayment is expected solely from the collateral. All loans of $0.5 million or more that are classified as non-accrual are identified for impairment analysis. The policy for recognizing income on impaired loans is consistent with the non-accrual policy. Impaired loans, or portions thereof, are charged off when deemed uncollectible.

Loans on which the accrual of interest has been discontinued amounted to $7.4 million and $10.6 million as of March 31, 2014 and December 31, 2013, respectively. If interest on those loans had been accrued, such income would have approximated $0.1 and $0.6 million as of March 31, 2014 and December 31, 2013, respectively. No interest income was recorded related to these loans as of March 31, 2014, and $0.1 million of interest income was recorded as of December 31, 2013. Accruing loans past due 90 days or more amounted to $1.5 million and $1.7 million as of March 31, 2014 and December 31, 2013, respectively.
Troubled Debt Restructurings:
Loans are considered restructured loans if concessions have been granted to borrowers that are experiencing financial difficulty. The concessions granted generally involve the modification of terms of the loan, such as changes in payment schedule or interest rate, which generally would not otherwise be considered. Restructured loans can involve loans remaining on non-accrual, moving to non-accrual or continuing on accrual status, depending on the individual facts and circumstances of the borrower. Non-accrual restructured loans are included and treated with all other non-accrual loans. In addition, all accruing restructured loans are being reported as troubled debt restructurings. Generally, restructured loans remain on non-accrual until the customer has attained a sustained period of repayment performance under the modified loan terms (generally a minimum of six months). However, performance prior to the restructuring, or significant events that coincide with the restructuring, are considered in assessing whether the borrower can meet the new terms and whether the loan should be returned to or maintained on non-accrual status. If the borrower’s ability to meet the revised payment schedule is not reasonably assured, the loan remains on non-accrual. Based on the above, the Company had $4.9 million and $5.7 million of non-accruing loans that were restructured and remained on non-accrual status as of March 31, 2014 and December 31, 2013, respectively. In addition, the Company had $1.7 million of restructured loans that were restored to accrual status based on a sustained period of repayment performance as of March 31, 2014, compared to $2.0 million as of December 31, 2013.

		March 31,		December 31,			Change
		2014		2013
		(Dollars in Thousands)
Loans secured by real estate:
Construction, land development and other land loans		$	3,724	$	3,837		$	(113	)
Secured by 1-4 family residential properties			763		1,067			(304	)
Secured by non-farm, non-residential properties			1,504		2,418			(914	)
Commercial and industrial loans			340		344			(4	)
Total		$	6,331	$	7,666		$	(1,335	)
All loans $0.5 million and over, modified in a troubled debt restructuring and rated substandard or lower, are evaluated for impairment. The nature and extent of impairment of restructured loans, including those which have experienced a subsequent payment default, are considered in the determination of an appropriate level of allowance for loan losses. This evaluation resulted in an allowance for loan losses on these restructured loans of $0.2 million and $0.8 million as of March 31, 2014 and December 31, 2013, respectively.

	Valuation adjustments are primarily recorded in other non-interest expense; adjustments are also recorded as a charge to the allowance for loan losses if incurred within 60 days after the date of transfer from loans. Valuation adjustments are primarily post-foreclosure write-downs that are a result of continued declining property values based on updated appraisals or other indications of value, such as offers to purchase.

	10. SHORT-TERM BORROWINGS
	Short-term borrowings consist of federal funds purchased and securities sold under repurchase agreements. Federal funds purchased generally mature within one to four days. There were no federal funds purchased outstanding as of March 31, 2014 or December 31, 2013.
	Securities sold under repurchase agreements, which are secured borrowings, generally are reflected at the amount of cash received in connection with the transaction. The Company may be required to provide additional collateral based on the fair value of the underlying securities. The Company monitors the fair value of the underlying securities on a daily basis. Securities sold under repurchase agreements as of March 31, 2014 and December 31, 2013 were $0.8 and $1.2 million, respectively.
	As of March 31, 2014, the Bank had $18.8 million in available federal fund lines from correspondent banks.

	The Company uses FHLB advances as an alternative to funding sources with similar maturities, such as certificates of deposit or other deposit programs. These advances generally offer more attractive rates when compared to other mid-term financing options. They are also flexible, allowing the Company to quickly obtain the necessary maturities and rates that best suit its overall asset/liability strategy. The Company had FHLB advances outstanding of $5.0 million as of March 31, 2014 and December 31, 2013, and assets pledged associated with these advances of $6.4 million and $5.1 million, respectively.
	As of March 31, 2014, the Bank had $167.7 million in available credit from the FHLB.

	The Company files a consolidated income tax return with the Federal government and the State of Alabama. ALC files a Mississippi state income tax return related to operations from its Mississippi branches. The Company is currently open to audit under the statute of limitations by the Internal Revenue Service and the states in which it files for the years ended December 31, 2010 through 2013.
	As of March 31, 2014, the Company had no unrecognized tax benefits related to federal or state income tax matters and does not anticipate any material increase or decrease in unrecognized tax benefits relative to any tax positions taken prior to March 31, 2014. As of March 31, 2014, the Company had accrued no interest and no penalties related to uncertain tax positions.
	The consolidated tax expense differed from the amount computed by applying the federal statutory income tax rate of 34.0%, as described in the following table:

	The Company had a net deferred tax asset of $9.6 million and $10.8 million as of March 31, 2014 and December 31, 2013, respectively. The reduction in the net deferred tax asset resulted primarily from decreases in deferred tax assets and liabilities related to book-tax timing differences associated with the provision for loan losses, OREO write-downs and increases in net unrealized gains on securities available-for-sale.

Commitments And Contingencies Disclosure [Abstract]	'
Guarantees, Commitments and Contingencies	'
	14. GUARANTEES, COMMITMENTS AND CONTINGENCIES
	The Bank’s exposure to credit loss in the event of nonperformance by the other party for commitments to make loans and standby letters of credit is represented by the contractual amount of those instruments. The Bank uses the same credit policies in making these commitments as it does for on-balance sheet instruments. For interest rate swap transactions and commitments to purchase or sell securities for forward delivery, the contract or notional amounts do not represent exposure to credit loss. The Bank controls the credit risk of these derivative instruments through credit approvals, limits and monitoring procedures. Certain derivative contracts have credit risk for the carrying value plus the amount to replace such contracts in the event of counterparty default. All of the Bank’s financial instruments are held for risk management and not for trading purposes. During the quarters ended March 31, 2014 and 2013, there were no credit losses associated with derivative contracts.
	In the normal course of business, there are outstanding commitments and contingent liabilities, such as commitments to extend credit, letters of credit and others that are not included in the consolidated financial statements. The financial instruments involve, to varying degrees, elements of credit and interest rate risk in excess of amounts recognized in the financial statements. A summary of these commitments and contingent liabilities is presented below:
		March 31,		December 31,
		2014		2013
		(Dollars in Thousands)
	Standby Letters of Credit	$	931	$	931
	Commitments to Extend Credit	$	24,672	$	28,875
	Standby letters of credit are contingent commitments issued by the Bank generally to guarantee the performance of a customer to a third party. The Bank has recourse against the customer for any amount that it is required to pay to a third party under a standby letter of credit. Revenues are recognized over the lives of the standby letters of credit. The potential amount of future payments that the Bank could be required to make under its standby letters of credit, which represents the Bank’s total credit risk, are listed in the table above.
	Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. The Bank evaluates each customer’s creditworthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary by the Bank upon extension of credit, is based on management’s credit evaluation of the counterparty. Collateral held varies but may include accounts receivable, inventory, property, plant and equipment and income-producing commercial properties.
	Commitments to purchase securities for delayed delivery require the Bank to purchase a specified security at a specified price for delivery on a specified date. Similarly, commitments to sell securities for delayed delivery require the Bank to sell a specified security at a specified price for delivery on a specified date. Market risk arises from potential movements in security values and interest rates between the commitment and delivery dates. As of March 31, 2014, there was $3.0 million in outstanding commitments to purchase securities for delayed delivery and no outstanding commitments to sell securities for delayed delivery. As of December 31, 2013, there was $3.0 million outstanding commitments to purchase securities for delayed delivery and no outstanding commitments to sell securities for delayed delivery.
	Litigation
	On September 27, 2007, Malcomb Graves Automotive, LLC (“Graves Automotive”), Malcomb Graves and Tina Graves filed a lawsuit in the Circuit Court of Shelby County, Alabama against USBI, the Bank, ALC and their respective directors and officers seeking an unspecified amount of compensatory and punitive damages. The original complaint asserted eighteen separate counts against USBI, the Bank, ALC and their respective directors and officers, all related to an alleged oral agreement under which Graves Automotive would sell automobiles repossessed by ALC in return for a fee. Among other things, the complaint alleged that the defendants committed fraud in allegedly misrepresenting to Graves Automotive the amounts that Graves Automotive owed on certain loans and in failing to reimburse Graves Automotive for amounts owed to Graves Automotive in connection with its sale of repossessed ALC automobiles. Through a series of motions to dismiss, all defendants have been dismissed except for ALC. Further, through a series of motions to dismiss and amendments to the complaint, only two counts remain pending against ALC – one for unjust enrichment and one for breach of contract. Because Graves Automotive had been unable to produce any documents supporting these remaining claims, on September 30, 2013, the court entered an order requiring Graves Automotive to produce a number of categories of specific documents evidencing the amounts allegedly owed to it by ALC. After the deadline to produce the documents had passed, ALC filed a Motion to Dismiss for failure to comply with the discovery order or, in the alternative, Motion for Summary Judgment based upon Graves Automotive’s inability to produce evidence supporting its claims. In response, Graves recently submitted an affidavit and produced a number of documents purportedly supporting its claims and damages. ALC is currently in the process of supplementing its Motion to Dismiss, or in the Alternative, Motion for Summary Judgment to address Graves Automotive’s recent production. This motion is currently set for hearing on May 20, 2014, but the parties anticipate that the hearing date will be continued while ALC and Graves Automotive work to schedule a mediation. ALC has previously made a nominal settlement offer to avoid the costs associated with additional litigation. ALC has yet to receive a response to this offer. ALC continues to deny the allegations against it in the lawsuit with respect to the remaining claims and intends to vigorously defend itself in this matter. Given the lack of discovery conducted, it is too early to assess the likelihood of a resolution of the remaining claims in this matter or the possibility of an unfavorable outcome.
	On December 2, 2013, Wayne Allen Russell filed a lawsuit against the Bank in the Circuit Court of Tuscaloosa County, alleging that the Bank wrongfully foreclosed on a parcel of property owned by Russell that was subject to a mortgage in favor of the Bank. Mr. Russell alleges that the loan secured by the mortgage had been satisfied in full from the proceeds of a prior foreclosure of additional properties subject to the same mortgage. Mr. Russell seeks an unspecified amount of damages. The Bank denies Mr. Russell’s allegations and will vigorously defend the lawsuit.
	The Company is also party to other litigation, and the Company intends to vigorously defend itself in all such litigation. In the opinion of the Company, based on review and consultation with legal counsel, the outcome of such other litigation should not have a material adverse effect on the Company’s consolidated financial statements or results of operations.

Accounting Changes And Error Corrections [Abstract]	'
Recent Accounting Pronouncements	'
	In January 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-04, Receivables – Troubled Debt Restructurings by Creditors (Subtopic 310-40): Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure (a consensus of the FASB Emerging Issues Task Force). ASU 2014-04 clarifies when an “in substance repossession or foreclosure” occurs, that is, when a creditor should be considered to have received physical possession of residential real estate property collateralizing a consumer mortgage loan, such that all or a portion of the loan should be derecognized and the real estate property recognized. ASU 2014-04 states that a creditor is considered to have received physical possession of residential real estate property collateralizing a consumer mortgage loan, upon either the creditor obtaining legal title to the residential real estate property upon completion of a foreclosure, or the borrower conveying all interest in the residential real estate property to the creditor to satisfy that loan through completion of a deed in lieu of foreclosure or through a similar legal agreement. The amendments of ASU 2014-04 also require interim and annual disclosure of both the amount of foreclosed residential real estate property held by the creditor and the recorded investment in consumer mortgage loans collateralized by residential real estate properties that are in the process of foreclosure. The amendments of ASU 2014-04 are effective for interim and annual periods beginning after December 15, 2014 and may be applied using either a modified retrospective transition method or a prospective transition method as described in ASU 2014-04. The adoption of ASU 2014-04 is not expected to have a significant impact on the Company’s consolidated financial position, results of operations or cash flows.
	In January 2014, the FASB issued ASU 2014-01, Investments – Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Qualified Affordable Housing Projects (a consensus of the FASB Emerging Issues Task Force). ASU 2014-01 permits reporting entities that invest in qualified affordable housing projects to elect to account for those investments using the “proportional amortization method” if certain conditions are met. Under this method, an entity amortizes the initial cost of the investment in proportion to the tax credits and other tax benefits received and recognizes the net investment performance in the income statement as a component of income tax expense (benefit). The decision to apply the proportional amortization method of accounting is an accounting policy decision and should be applied consistently to all qualifying affordable housing project investments. ASU 2014-01 should be applied retrospectively to all periods presented and is effective for annual and interim reporting periods beginning after December 15, 2014. The Company does not have a significant amount of investments in qualified affordable housing projects that qualify for the low income housing tax credit. Such investments are currently either consolidated in the Company’s financial statements or accounted for as cost method investments. The adoption of ASU 2014-01 is not expected to have a significant impact on the Company’s consolidated financial position, results of operations or cash flows.
	In July 2013, the FASB issued ASU 2013-11, Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists (a consensus of the FASB Emerging Issues Task Force). ASU 2013-11 provides that an entity’s unrecognized tax benefit, or a portion of its unrecognized tax benefit, should be presented in its financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward, with one exception. The exception states that to the extent a net operating loss carryforward, a similar tax loss, or a tax credit carryforward is not available at the reporting date under the tax law of the applicable jurisdiction to settle any additional income taxes that would result from the disallowance of a tax position, or the tax law of the applicable jurisdiction does not require the entity to use, and the entity does not intend to use, the deferred tax asset for such purpose, the unrecognized tax benefit should be presented in the financial statements as a liability and should not be combined with deferred tax assets. ASU 2013-11 applies prospectively for all entities that have unrecognized tax benefits when a net operating loss carryforward, a similar tax loss, or tax credit carryforward exists at the reporting date. ASU 2013-11 is effective for fiscal years, and interim periods within those years beginning after December 15, 2013. The Company adopted ASU 2013-11 on January 1, 2014. The adoption of ASU 2013-11 did not have a significant impact on the Company’s consolidated financial position, results of operations or cash flows.
Fair Value Measurement and Disclosures	'
	The Company follows the provisions of ASC Topic 820, Fair Value Measurements and Disclosures, which defines fair value, establishes a framework for measuring fair value and expands disclosures about fair value measurements.
	Fair Value Hierarchy
	The assumptions used in the estimation of the fair value of the Company’s financial instruments are detailed below. Where quoted prices are not available, fair values are based on estimates using discounted cash flows and other valuation techniques. The use of discounted cash flows can be significantly affected by the assumptions used, including the discount rate and estimates of future cash flows. The following disclosures should not be considered a surrogate of the liquidation value of the Company, but rather represent a good-faith estimate of the increase or decrease in value of financial instruments held by the Company since purchase, origination or issuance.
	Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between willing market participants at the measurement date. In determining fair value, the Company uses various methods, including market, income and cost approaches. Based on these approaches, the Company often utilizes certain assumptions that market participants would use in pricing the asset or liability, including assumptions about risk and/or the risks inherent in the inputs to the valuation technique. These inputs can be readily observable, market corroborated or generally unobservable inputs. The Company utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs. Based on the observability of the inputs used in the valuation techniques, the Company is required to provide the following information according to the fair value hierarchy. The fair value hierarchy ranks the quality and reliability of the information used to determine fair values. Assets and liabilities carried at fair value will be classified and disclosed in one of the following three categories:
		•		Level 1 — Valuations for assets and liabilities traded in active exchange markets, such as the New York Stock Exchange or NASDAQ. Valuations are obtained from readily available pricing sources for market transactions involving identical assets or liabilities.
		•		Level 2 — Valuations for assets and liabilities traded in less active dealer or broker markets. Valuations are obtained from third-party pricing services for identical or similar assets or liabilities.
		•		Level 3 — Valuations for assets and liabilities that are derived from other valuation methodologies, including option pricing models, discounted cash flow models and similar techniques, and not based on market exchange, dealer or broker-traded transactions. Level 3 valuations incorporate certain assumptions and projections in determining the fair value assigned to such assets or liabilities.
Accounting by Creditors for Impairment of a Loan	'
	Loan impairment is reported when full payment under the loan terms is not expected. Impaired loans are carried at the present value of estimated future cash flows using the loan’s existing rate or the fair value of collateral if the loan is collateral dependent. A portion of the allowance for loan losses is allocated to impaired loans if the value of such loans is deemed to be less than the unpaid balance. If these allocations cause the allowance for loan losses to increase, such increase is reported as a component of the provision for loan losses. When an impaired loan is determined to be collateral dependent, the fair value is determined through the utilization of a third-party appraisal. It is the policy of the Company to update appraisals every 18-24 months. The types of collateral influence the frequency of obtaining updated appraisals. Management knows the market trends of collateral values well and monitors trends in sales and valuations in all of the various categories of collateral. These trends influence how often new appraisals are obtained within the 18-24 month timeframe. An example would be loans collateralized by residential subdivision lots. The values of this type of collateral have been volatile in recent years, and, therefore, appraisals are generally updated at the lower end of the timeframe (i.e., closer to 18 months), while timberland appraisals, which have been less volatile in recent years, would be updated closer to the upper end of the timeframe (i.e., closer to 24 months). Any observed trend indicating significant changes in valuations would require updated appraisals. Based on experience, current appraisals are discounted 9% for estimated costs associated with foreclosures and costs to sell. If a loan is evaluated for impairment under ASC Topic 310-10-35, Accounting by Creditors for Impairment of a Loan, and the appraisal is outdated, a new appraisal is ordered. If the new appraisal is not received in sufficient time to assess any required impairment to meet financial reporting obligations, the old appraisal may be adjusted to reflect values observed in similar properties. After a new appraisal is obtained, the analysis is updated to reflect the new valuation. Loan losses are charged against the allowance when management believes that the uncollectability of a loan is confirmed. Loans, net of specific allowances for fair-value impairment, amounted to $3.4 million and $11.4 million as of March 31, 2014 and December 31, 2013, respectively. This valuation was derived using Level 3 inputs, consisting of appraisals of underlying collateral and discounted cash flow analysis.
Consolidation	'
	The Company has determined that these structures require evaluation as a variable interest entity (“VIE”) under ASC Topic 810, Consolidation. The Company consolidates one of the funds in which it has a 99.9% limited partnership interest. Assets recorded by the Company as a result of the consolidation totaled approximately $53,000 as of both March 31, 2014 and December 31, 2013.
Accounting for Tax Benefits Resulting from Investments in Affordable Housing Projects	'
	The remaining limited partnership investments are unconsolidated and are accounted for under the cost method as allowed under ASC Topic 325, Accounting for Tax Benefits Resulting from Investments in Affordable Housing Projects. The Company amortizes the excess of carrying value of the investment over its estimated residual value during the period in which tax credits are allocated to the investors.
Segment Reporting	'
	Under ASC Topic 280, Segment Reporting, certain information is disclosed for the two reportable operating segments of the Company. The reportable segments were determined using the internal management reporting system. These segments are comprised of USBI’s and the Bank’s significant subsidiaries. The accounting policies for each segment are the same as those described in Note 2, “Summary of Significant Accounting Policies,” of the Notes to Consolidated Financial Statements in USBI’s Annual Report on Form 10-K for the period ended December 31, 2013. The segment results include certain overhead allocations and intercompany transactions that were recorded at current market prices. All intercompany transactions have been eliminated to determine the consolidated balances. The results for the two reportable segments of the Company are included in the following table:
