	Note 1. General
	The accompanying unaudited condensed consolidated financial statements of First Community Bancshares, Inc. and subsidiaries (“First Community” or the “Company”) have been prepared in accordance with generally accepted accounting principles in the United States (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. In the opinion of management, all adjustments, including normal recurring accruals, necessary for a fair presentation have been made. All significant intercompany balances and transactions have been eliminated in consolidation. Operating results for the interim period are not necessarily indicative of the results that may be expected for the full calendar year.
	The condensed consolidated balance sheet as of December 31, 2012, has been derived from the audited consolidated financial statements included in the Company’s 2012 Annual Report on Form 10-K (the “2012 Form 10-K”), as filed with the Securities and Exchange Commission (the “SEC”) on March 15, 2013. Certain information and footnote disclosures normally included in annual consolidated financial statements prepared in accordance with GAAP have been omitted in accordance with standards for the preparation of interim consolidated financial statements. These consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s 2012 Form 10-K.
	The Company operates in one business segment, Community Banking. The Community Banking segment consists of all operations, including commercial and consumer banking, lending activities, wealth management, and insurance services.
	Significant Accounting Policies
	A complete and detailed description of the Company’s significant accounting policies is included in Note 1, “Summary of Significant Accounting Policies,” of the Notes to Consolidated Financial Statements in Part II, Item 8, “Financial and Supplementary Data,” of the Company’s 2012 Form 10-K and Note 1, “General,” of the Notes to Condensed Consolidated Financial Statements (Unaudited) in Part I, Item 1, “Financial Statements,” herein. Additional discussion of the Company’s application of critical accounting estimates is included within “Application of Critical Accounting Estimates” in Item 2, “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” herein.
	Reclassifications and Corrections
	The Company has made certain reclassifications of prior years’ amounts necessary to conform to the current year’s presentation. These reclassifications had no effect on the Company’s financial position, stockholders’ equity, or results of operations.
	Recent Accounting Pronouncements
	There were no recent accounting pronouncements that had, or are likely to have, a material effect on the Company’s financial position or results of operations.
	Earnings per Common Share
	Basic earnings per common share is determined by dividing net income available to common shareholders by the weighted average common shares outstanding. Diluted earnings per common share is determined by dividing net income by the weighted average common shares outstanding, including diluted shares for stock options, warrants, contingently issuable shares, and convertible preferred shares. The calculation for basic and diluted earnings per common share follows:

	Diluted earnings per common share	$	0.26	$	0.47	$	0.85	$	1
	The Company’s Series A Noncumulative Convertible Preferred Stock (“Series A Preferred Stock”) carries a 6% dividend rate. Each share is convertible into 69 shares of the Company’s Common Stock (“Common Stock”) at any time and mandatorily converts after five years. The Company may redeem the shares at face value after May 20, 2014. There were 15,471 shares of Series A Preferred Stock outstanding at September 30, 2013, 17,421 shares outstanding at December 31, 2012, and 17,921 shares outstanding at September 30, 2012.
	The following outstanding options to purchase Common Stock were excluded from the calculation of diluted earnings per share because the exercise price was greater than the market value of the Common Stock, which would result in an antidilutive effect on diluted earnings per share:

The Company reviews its investment portfolio on a quarterly basis for indications of other-than-temporary impairment (“OTTI”). The analysis differs depending upon the type of investment security being analyzed. For debt securities, the Company has determined that it does not intend to sell securities that are impaired and has asserted that it is not more likely than not that the Company will have to sell impaired securities before recovery of the impairment occurs. This determination is based upon the Company’s investment strategy for the particular type of debt security and its cash flow needs, liquidity position, capital adequacy, and interest rate risk position.
For nonbeneficial interest debt securities, the Company analyzes several qualitative factors such as the severity and duration of the impairment, adverse conditions within the issuing industry, prospects for the issuer, performance of the security, changes in rating by rating agencies, and other qualitative factors to determine if the impairment will be recovered. Nonbeneficial interest debt securities consist of U.S. Treasury securities, municipal securities, and single issue trust preferred securities. If it is determined that there is evidence that the impairment will not be recovered, the Company performs a present value calculation to determine the amount of impairment and records any credit-related OTTI through earnings and noncredit-related OTTI through other comprehensive income (“OCI”). During the three and nine months ended September 30, 2013 and 2012, the Company incurred no OTTI charges related to nonbeneficial interest debt securities. Temporary impairment on these securities is primarily related to changes in interest rates, certain disruptions in credit markets, destabilization in the Eurozone, and other current economic factors.
For beneficial interest debt securities, the Company reviews cash flow analyses on each applicable security to determine if an adverse change in cash flows expected to be collected has occurred. Beneficial interest debt securities consist of corporate securities and mortgage-backed securities (“MBS”). An adverse change in cash flows expected to be collected has occurred if the present value of cash flows previously projected is greater than the present value of cash flows projected at the current reporting date and less than the current book value. If an adverse change in cash flows is deemed to have occurred, then an OTTI has occurred. The Company then compares the present value of cash flows using the current yield for the current reporting period to the reference amount, or current net book value, to determine the credit-related OTTI. The credit-related OTTI is then recorded through earnings and the noncredit-related OTTI is accounted for in OCI. During the three and nine months ended September 30, 2013, the Company incurred no credit-related OTTI charges associated with beneficial interest debt securities. During the three and nine months ended September 30, 2012, the Company incurred credit-related OTTI charges on beneficial interest debt securities of $942 thousand. These charges were related to a non-Agency MBS. Temporary impairment on the Agency MBS is primarily related to changes in interest rates.
For the non-Agency Alt-A residential MBS, the Company uses a discounted cash flow model with the following assumptions: constant prepayment rate of 9.7%, a customized constant default rate scenario that assumes approximately 12% of the remaining underlying mortgages will default within three years, and a customized loss severity rate scenario that ramps the loss rate down from 66% to 15% over the course of approximately six years.
The following table provides a cumulative roll forward of credit losses recognized in earnings for debt securities for which a portion of the OTTI is recognized in OCI:

-1	The beginning balance includes credit related losses included in OTTI charges recognized on debt securities in prior periods.
For equity securities, the Company reviews for OTTI based upon the prospects of the underlying companies, analysts’ expectations, and certain other qualitative factors to determine if impairment is recoverable over a foreseeable period of time. During the three and nine months ended September 30, 2013 and 2012, the Company recognized no OTTI charges on equity securities.

Allowance for Loan Losses and Credit Quality Indicators	'
	Note 4. Allowance for Loan Losses and Credit Quality Indicators
	Allowance for Loan Losses
	The allowance for loan losses is maintained at a level management deems sufficient to absorb probable loan losses inherent in the loan portfolio. The allowance is increased by charges to earnings in the form of provision for loan losses and recoveries of prior loan charge-offs, and decreased by loans charged off. The provision is calculated to bring the allowance to a level which, according to a systematic process of measurement, reflects the amount management estimates is needed to absorb probable losses within the portfolio. While management utilizes its best judgment and information available, the ultimate adequacy of the allowance is dependent upon a variety of factors beyond the Company’s control, including, among other things, the performance of the Company’s loan portfolio, the economy, changes in interest rates, and the view of the regulatory authorities toward loan classifications. Purchased credit impaired loan pools are evaluated separately from the non-purchased credit impaired portfolio for impairment.
	Management performs quarterly assessments to determine the appropriate level of the allowance for loan losses. Differences between actual loan loss experience and estimates are reflected through adjustments that are made by increasing or decreasing the allowance based upon current measurement criteria. Commercial, consumer real estate, and non-real estate consumer loan portfolios are evaluated separately for purposes of determining the allowance. The specific components of the allowance include allocations to individual commercial loans and credit relationships and allocations to the remaining nonhomogeneous and homogeneous pools of loans that have been deemed impaired. Additionally, a loan that becomes adversely classified is removed from a group of loans with similar risk characteristics that are not classified to evaluate the removed loan collectively in a group of adversely classified loans with similar risk characteristics. Management’s general reserve allocations are based on judgment of qualitative and quantitative factors about macro and micro economic conditions reflected within the portfolio of loans and the economy as a whole. Factors considered in this evaluation include, but are not necessarily limited to, probable losses from loan and other credit arrangements, general economic conditions, changes in credit concentrations or pledged collateral, historical loan loss experience, and trends in portfolio volume, maturities, composition, delinquencies, and nonaccruals. Historical loss rates for each risk grade of commercial loans are adjusted by environmental factors to estimate the amount of reserve needed by segment. While management has allocated the allowance for loan losses to various portfolio segments, the entire allowance is available for use against any type of loan loss deemed appropriate by management.
	Purchased performing loans are recorded at fair value and include credit and interest rate marks associated with acquisition accounting adjustments, as accounted for under the contractual cash flow method of accounting. The fair value adjustment is accreted as an adjustment to yield over the estimated contractual lives of the loans. There is no allowance for loan losses established at the acquisition date for acquired performing loans. In accordance with GAAP, there was no carryover of previously established allowance for loan losses on acquired portfolios. A provision for loan losses is recorded for any credit deterioration in these acquired loans subsequent to the acquisition. The provision established for covered acquired impaired loans is offset by an adjustment to the FDIC loss share receivable to reflect the indemnified portion of the post-acquisition exposure.

	Credit Quality Indicators
	The Company identifies loans for potential impairment through a variety of means including, but not limited to, ongoing loan review, renewal processes, delinquency data, market communications, and public information. If it is determined that it is probable that the Company will not collect all principal and interest amounts contractually due, the loan is generally deemed to be impaired.
	The following tables present the Company’s recorded investment in loans considered to be impaired, excluding purchased credit impaired loans, and related information on those loans for the periods indicated:

As part of the ongoing monitoring of the credit quality of the Company’s loan portfolio, management tracks certain credit quality indicators including trends related to the risk rating of commercial loans, the level of classified commercial loans, net charge-offs, nonperforming loans, and general economic conditions. The Company’s loan review function generally reviews all commercial loan relationships greater than $3.0 million on an annual basis and at various times through the year. Smaller commercial and retail loans are sampled for review throughout the year by our internal loan review department. Through the loan review process, loans are identified for upgrade or downgrade in risk rating and changed to reflect current information as part of the process.
The Company utilizes a risk grading matrix to assign a risk grade to each of its loans. A description of the general characteristics of the risk grades is as follows:
	•		Pass – This grade includes loans to borrowers of acceptable credit quality and risk. The Company further differentiates within this grade based upon borrower characteristics which include: capital strength, earnings stability, liquidity leverage, and industry.
	•		Special Mention – This grade includes loans that require more than a normal degree of supervision and attention. These loans have all the characteristics of an adequate asset, but due to being adversely affected by economic or financial conditions have a potential weakness that deserves management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loan.
	•		Substandard – This grade includes loans that have well defined weaknesses which make payment default or principal exposure possible, but not yet certain. Such loans are apt to be dependent upon collateral liquidation, a secondary source of repayment, or an event outside of the normal course of business to meet the repayment terms.
	•		Doubtful – This grade includes loans that are placed on nonaccrual status. These loans have all the weaknesses inherent in a substandard loan with the added factor that the weaknesses are so severe that collection or liquidation in full, on the basis of current existing facts, conditions and values, is extremely unlikely, but because of certain specific pending factors, the amount of loss cannot yet be determined.
	•		Loss – This grade includes loans that are to be charged off or charged down when payment is acknowledged to be uncertain or when the timing or value of payments cannot be determined. “Loss” is not intended to imply that the asset has no recovery or salvage value, but simply that it is not practical or desirable to defer writing off all or some portion of the loan, even though partial recovery may be realized in the future.
The following tables present the Company’s investment in loans held for investment by internal credit grade indicator at September 30, 2013, and December 31, 2012. Purchased credit impaired loan pools have been disaggregated in the following tables for disclosure purposes. Non-covered special mention and substandard loans declined between December 31, 2012, and September 30, 2013, due primarily to loan work-out activity across the portfolio coupled with continued credit improvement in the Peoples’ acquired loan portfolio.

There were no non-covered accruing loans contractually past due 90 days or more at September 30, 2013, and December 31, 2012. There were no covered accruing loans contractually past due 90 days or more at December 31, 2012, and $82 thousand at September 30, 2013. Acquired loans that are past due continue to accrue interest through the accretable yield under the accretion method of accounting and therefore are not considered to be nonaccrual. Purchased credit impaired loan pools have been disaggregated in the following tables for disclosure purposes.

The Company’s troubled debt restructurings (“TDRs”) totaled $11.92 million at September 30, 2013, and $12.05 million at December 31, 2012, which are reported net of those on nonaccrual status of $2.66 million and $3.83 million, respectively. Accruing nonperforming TDRs amounted to $2.23 million, or 18.69% of total accruing TDRs at September 30, 2013, and $6.01 million, or 49.88% of total TDRs at December 31, 2012. The allowance for loan losses included reserves related to TDRs of $1.69 million and $1.87 million at September 30, 2013, and December 31, 2012, respectively. Interest income recognized on TDRs for the three and nine months ended September 30, 2013, totaled $183 thousand and $422 thousand, respectively. Interest income recognized on TDRs for the three and nine months ended September 30, 2012, totaled $62 thousand and $237 thousand, respectively. There were no covered loans recorded as TDRs at September 30, 2013. A loan acquired with credit deterioration through a business combination, for which a discount exists, is generally not considered a TDR as long as the loan remains in the loan pool.
When restructuring loans for borrowers experiencing financial difficulty, the Company may make concessions in interest rates, loan terms and/or amortization terms. All restructured loans to borrowers experiencing financial difficulty in excess of $250 thousand are evaluated for a specific reserve based on either the collateral or net present value method, whichever is most applicable. Restructured loans under $250 thousand are subject to the reserve calculation at the historical loss rate for classified loans. Certain TDRs are classified as nonperforming at the time of restructuring and are returned to performing status after six months of satisfactory payment performance; however, these loans remain identified as impaired until full payment or other satisfaction of the obligation occurs.
The following tables detail loans modified as TDRs that were restructured during the three and nine months ended September 30, 2013 and 2012 by type of concession made and loan class. The post-modification recorded investment represents the loan balance immediately following modification.

FDIC Indemnification Asset	'
	Note 5. FDIC Indemnification Asset
	On June 8, 2012, the Company entered into a purchase and assumption agreement with loss share arrangements with the FDIC to purchase certain assets and assume substantially all of the customer deposits and certain liabilities of Waccamaw Bank. The FDIC indemnification asset is measured separately from the related covered asset, as it is not contractually embedded in the assets and is not transferable with the assets should the Company choose to dispose of them. Fair value was estimated at the acquisition date using projected cash flows related to the loss share agreements based on the expected reimbursements for losses and the applicable loss share percentages. Under the loss share agreements, the FDIC has agreed to cover 80% of most loan and foreclosed real estate losses. These expected reimbursements do not include reimbursable amounts related to future covered expenditures. These cash flows were discounted to reflect the uncertainty of the timing and receipt of the loss sharing reimbursement from the FDIC. The Company will offset any recorded provision for loan losses related to acquired covered loans by recording an increase in the FDIC indemnification asset by the increase in expected cash flows, which is the result of a decrease in expected cash flows of acquired loans. An increase in cash flows on acquired loans results in a decrease in cash flows on the FDIC indemnification asset, which is recognized in the future as amortization through noninterest income over the shorter of the remaining life of the FDIC indemnification asset or the underlying loans. The Company incurs expenses related to the assets indemnified by the FDIC, and pursuant to the loss share agreements certain costs are reimbursable by the FDIC and are included in monthly and quarterly claims made by the Company. The estimates of reimbursements are netted against these covered expenses in the income statement.

	Securities sold under agreements to repurchase consisted of retail overnight and term repurchase agreements of $64.65 million at September 30, 2013, and $77.92 million at December 31, 2012, and wholesale repurchase agreements of $50.00 million at September 30, 2013, and $58.20 million at December 31, 2012. During the first quarter of 2013, the Company prepaid wholesale repurchase agreements totaling $8.15 million that resulted in a $79 thousand gain. The weighted average rate of wholesale repurchase agreements was 3.71% at September 30, 2013, and 3.34% at December 31, 2012. Securities sold under agreements to repurchase are collateralized with agency MBS and municipal securities.
	FHLB borrowings included convertible and callable advances totaling $150.00 million at September 30, 2013, and $155.28 million at December 31, 2012, and fixed rate credit of $6.27 million at December 31, 2012. During the first quarter of 2013, the Company prepaid FHLB borrowings totaling $11.47 million that resulted in a $217 thousand gain. The callable advances may be redeemed at quarterly intervals. These call options may substantially shorten the lives of these instruments. If these advances are called, the debt may be paid in full or converted to another FHLB credit product. Prepayment of the advances may result in substantial penalties based upon the differential between contractual note rates and current advance rates for similar maturities. The weighted average rate of FHLB borrowings was 4.12% at September 30, 2013, and 3.86% at December 31, 2012. Advances from the FHLB were secured by qualifying loans of $1.10 billion at September 30, 2013, and $998.14 million at December 31, 2012. At September 30, 2013, unused borrowing capacity with the FHLB totaled $325.72 million.
	At September 30, 2013, the FHLB borrowings had approximate contractual maturities between three and eight years. The scheduled maturities of the advances are as follows:

The Trust was able to purchase the Debentures through the issuance of trust preferred securities which had substantially identical terms as the Debentures. The Debentures mature on October 8, 2033, and are currently callable. The net proceeds from the offering were contributed as capital to the Bank to support further growth. The Company’s obligations under the Debentures and other relevant Trust agreements, in aggregate, constitute a full and unconditional guarantee by the Company of the Trust’s obligations.

Derivative Instruments and Hedging Activities	'
	Note 9. Derivative Instruments and Hedging Activities
	The Company uses derivative instruments primarily to protect against the risk of adverse price or interest rate movements on the value of certain assets and liabilities and on future cash flows. These derivatives may consist of interest rate swaps, floors, caps, collars, futures, forward contracts, and written and purchased options. Derivative instruments represent contracts between parties that usually require little or no initial net investment and result in one party delivering cash or another asset to the other party based on a notional amount and an underlying asset as specified in the contract. Derivative assets and liabilities are recorded at fair value on the balance sheet.
	Like other financial instruments, derivatives contain an element of credit risk due to the possibility the Company may incur a loss if a counterparty fails to meet its contractual obligations. This risk is measured as the expected positive replacement value of contracts. All derivative contracts may be executed only with exchanges or counterparties approved by the Company’s Asset/Liability Management Committee.
	The primary derivative instrument the Company uses is interest rate lock commitments (“IRLCs”). Generally, this instrument helps the Company meet customer financing needs. Market risk represents the possibility that economic value or net interest income will be adversely affected by fluctuations in external factors such as interest rates, market-driven loan rates, prices, or other economic factors.
	In the normal course of business, the Company sells originated mortgage loans into the secondary mortgage loan market. The Company enters into IRLCs to provide potential borrowers an interest rate guarantee. Once a mortgage loan is closed and funded, it is included within loans held for sale and awaits sale and delivery into the secondary market. From the loan closing date through the date of sale into the secondary market, the Company has exposure to interest rate movement resulting from the risk that interest rates will change from the rate quoted to the borrower. Due to these interest rate fluctuations, the Company’s balance of mortgage loans held for sale is subject to changes in fair value. Typically, the fair value of these loans decline when interest rates increase and rise when interest rates decrease.
	The following table presents the aggregate contractual or notional amounts of derivative financial instruments as of the dates indicated:

Fair_Value

Fair Value	9 Months Ended

Fair Value	'
	Note 10. Fair Value
	Financial Instruments Measured at Fair Value
	Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. A fair value measurement assumes that the transaction to sell the asset or transfer the liability occurs in the principal market for the asset or liability or, in the absence of a principal market, the most advantageous market for the asset or liability. The price in the principal, or most advantageous, market used to measure the fair value of the asset or liability shall not be adjusted for transaction costs. An orderly transaction is a transaction that assumes exposure to the market for a period prior to the measurement date to allow for marketing activities that are usual and customary for transactions involving such assets and liabilities; it is not a forced transaction. Market participants are buyers and sellers in the principal market that are (i) independent, (ii) knowledgeable, (iii) able to transact, and (iv) willing to transact.
	The fair value hierarchy is as follows:
		Level 1 Inputs –	Unadjusted quoted prices in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date.
		Level 2 Inputs –	Inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. These might include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability and provide a reasonable basis for fair value determination, such as interest rates, yield curves, volatilities, prepayment speeds, default rates, and credit risks, or inputs that are derived principally from observable market data.
		Level 3 Inputs –	Unobservable inputs for determining the fair values of assets or liabilities for which there is little, if any, market activity at the measurement date, using reasonable inputs and assumptions based on the best information at the time, to the extent that inputs are available without undue cost and effort. These inputs and assumptions may include model-derived inputs that are not corroborated by observable market data and an entity’s own assumptions.
	A description of the valuation methodologies used for instruments measured at fair value, as well as the general classification of such instruments pursuant to the valuation hierarchy, is set forth below. These valuation methodologies were applied to all of the Company’s assets and liabilities carried at fair value. In general, fair value is based upon quoted market prices, where available. If such quoted market prices are not available, fair value is based upon third party models that primarily use, as inputs, observable market-based parameters. Valuation adjustments may be made to ensure that financial instruments are recorded at fair value. These adjustments may include amounts to reflect counterparty credit quality, the Company’s creditworthiness, among other things, as well as unobservable parameters. Any such valuation adjustments are applied consistently over time. The Company’s valuation methodologies may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. While management believes the Company’s valuation methodologies are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different estimate of fair value at the reporting date.
	Securities Available-for-Sale. Securities classified as available-for-sale are reported at fair value utilizing Level 1, Level 2, and Level 3 inputs. Securities are classified as Level 1 within the valuation hierarchy when quoted prices are available in an active market. This includes securities whose value is based on quoted market prices in active markets for identical assets. The Company also uses Level 1 inputs for the valuation of equity securities traded in active markets.
	Securities are classified as Level 2 within the valuation hierarchy when the Company obtains fair value measurements from an independent pricing service. The fair value measurements consider observable data that may include dealer quotes, market spreads, cash flows, the U.S. Treasury yield curve, live trading levels, trade execution data, market consensus prepayment speeds, credit information, and the bond’s terms and conditions, among other things. Level 2 inputs are used to value U.S. government agency securities, single issue trust preferred securities, corporate securities, MBS, and certain equity securities that are not actively traded.
	Securities are classified as Level 3 within the valuation hierarchy in certain cases when there is limited activity or less transparency to the valuation inputs. In the absence of observable or corroborated market data, internally developed estimates that incorporate market-based assumptions are used when such information is available.
	Fair value models may be required when trading activity has declined significantly or does not exist, prices are not current or pricing variations are significant. The Company’s fair value from third party models utilizes modeling software that uses market participant data and knowledge of the structures of each individual security to develop cash flows specific to each security. The fair values of the securities are determined by using the cash flows developed by the fair value model and applying appropriate market observable discount rates. The discount rates are developed by determining credit spreads above a benchmark rate, such as LIBOR, and adding premiums for illiquidity developed based on a comparison of initial issuance spread to LIBOR versus a financial sector curve for recently issued debt to LIBOR. Specific securities that have increased uncertainty regarding the receipt of cash flows are discounted at higher rates due to the addition of a deal specific credit premium based on assumptions about the performance of the underlying collateral. Finally, internal fair value model pricing and external pricing observations are combined by assigning weights to each pricing observation. Pricing is reviewed for reasonableness based on the direction of the specific markets and the general economic indicators.
	Other Assets and Associated Liabilities. Securities held for trading purposes are recorded at fair value and included in “other assets” on the consolidated balance sheets. Securities held for trading purposes include assets related to employee deferred compensation plans. The assets associated with these plans are generally invested in equities and classified as Level 1. Deferred compensation liabilities, also classified as Level 1, are carried at the fair value of the obligation to the employee, which corresponds to the fair value of the invested assets.
	Derivatives. Derivatives are reported at fair value utilizing Level 2 inputs. The Company obtains dealer quotations based on observable data to value its derivatives.
	Impaired Loans. Certain impaired loans are reported on a nonrecurring basis at the fair value of the underlying collateral if repayment is expected solely from the collateral. Collateral values are estimated using Level 3 inputs based on appraisals adjusted for customized discounting criteria.
	The Company maintains an active and robust problem credit identification system. When a credit is identified as exhibiting characteristics of weakening, the Company will assess the credit for potential impairment. Examples of weakening include delinquency and deterioration of the borrower’s capacity to repay as determined by the Company’s regular credit review function. As part of the impairment review, the Company will evaluate the current collateral value. It is the Company’s standard practice to obtain updated third party collateral valuations to assist management in measuring potential impairment of a credit and the amount of the impairment to be recorded.
	Internal collateral valuations are generally performed within two to four weeks of the original identification of potential impairment and receipt of the third party valuation. The internal valuation is performed by comparing the original appraisal to current local real estate market conditions and experience and considers liquidation costs. The result of the internal valuation is compared to the outstanding loan balance, and, if warranted, a specific impairment reserve will be established at the completion of the internal evaluation.
	A third party evaluation is typically received within thirty to forty-five days of the completion of the internal evaluation. Once received, the third party evaluation is reviewed for reasonableness. Once the evaluation is reviewed and accepted, discounts to fair market value are applied based upon such factors as the bank’s historical liquidation experience of like collateral, and an estimated net realizable value is established. That estimated net realizable value is then compared to the outstanding loan balance to determine the amount of specific impairment reserve. The specific impairment reserve, if necessary, is adjusted to reflect the results of the updated evaluation. A specific impairment reserve is generally maintained on impaired loans during the time period while awaiting receipt of the third party evaluation as well as on impaired loans that continue to make some form of payment and liquidation is not imminent. Impaired loans not meeting the aforementioned criteria and that do not have a specific impairment reserve have usually been previously written down through a partial charge-off, to their net realizable value.
	The Company’s Special Assets staff assumes the management and monitoring of all loans determined to be impaired. While awaiting the completion of the third party appraisal, the Company generally begins to complete the tasks necessary to gain control of the collateral and prepare for liquidation, including, but not limited to engagement of counsel, inspection of collateral, and continued communication with the borrower, if appropriate. Special Assets staff also regularly reviews the relationship to identify any potential adverse developments during this time.
	Generally, the only difference between current appraised value, adjusted for liquidation costs, and the carrying amount of the loan less the specific reserve is any downward adjustment to the appraised value that the Company determines appropriate. These differences generally consist of costs to sell the property, as well as a deflator for the devaluation of property seen when banks are the sellers, and the Company deemed these adjustments as fair value adjustments.
	In the Company’s experience, it rarely returns loans to performing status after they have been partially charged off. Generally, credits identified as impaired move quickly through the process towards ultimate resolution.
	Other Real Estate Owned. The fair value of the Company’s other real estate owned is determined on a nonrecurring basis using Level 3 inputs based on current and prior appraisals, estimates of costs to sell, and proprietary qualitative adjustments.
	Goodwill. The fair value of the Company’s goodwill is reported on a nonrecurring basis when it has been adjusted to fair value. The values of the Company’s reporting units are determined using Level 3 inputs based on discounted cash flow and market multiple models.

Fair Value of Financial Instruments
Information used to determine fair value is highly subjective and judgmental in nature; therefore, the results may not be precise. Subjective factors may include estimates of cash flows, risk characteristics, credit quality, and interest rates, all of which are subject to change. Since the fair value is estimated as of the balance sheet date, the amounts that will actually be realized or paid upon settlement or maturity on these various instruments could be significantly different. The following summary describes the methodologies and assumptions used by the Company to estimate the fair value of certain financial instruments:
Cash and Cash Equivalents: The carrying amount of cash and due from banks and federal funds sold/purchased is considered equal to the fair value as a result of the short-term nature of these instruments.
Investment Securities: The determination of the fair value of available-for-sale securities is described within “Fair Value Measurements” presented above. The determination of the fair value of held-to-maturity securities is based on quoted market prices or dealer quotes.
Loans Held for Sale: Loans held for sale are recorded at the lower of cost or estimated fair value. The determination of the fair value of loans held for sale is based on the market price of similar loans.
Loans Held for Investment: The determination of the fair value of loans held for investment is based on discounted future cash flows using current rates for similar loans.
FDIC Receivable under Loss Share Agreements: The determination of the fair value is based on discounted future cash flows using current discount rates.
Accrued Interest Receivable/Payable: The carrying amount of accrued interest receivable/payable is considered equal to the fair value as a result of the short-term nature of these instruments.
Derivative Financial Instruments: The determination of the fair value of derivative financial instruments is described within “Fair Value Measurements” presented above.
Deferred Compensation Instruments: The determination of the fair value of deferred compensation instruments is described within “Fair Value Measurements” presented above.
Deposits and Securities Sold Under Agreements to Repurchase: The fair value of deposits without a stated maturity, including demand, interest-bearing demand, and savings, is considered equal to the carrying amount which is the amount payable on demand at the reporting date. The fair value of deposits and repurchase agreements with fixed maturities and rates is estimated using discounted future cash flows that apply interest rates currently being offered on instruments with similar characteristics and maturities.
FHLB and Other Indebtedness: The determination of the fair value of FHLB and other indebtedness is based on interest rates currently available to the Company for borrowings with similar characteristics and maturities. The determination of fair value for trust preferred obligations is based on credit spreads seen in the marketplace for similar issues.
Off-Balance Sheet Instruments: The value of off-balance sheet instruments, including commitments to extend credit, standby letters of credit, and financial guarantees, is considered equal to fair value. Due to the uncertainty involved in assessing the likelihood and timing of commitments being drawn upon, coupled with the lack of an established market and the wide diversity of fee structures, the Company does not believe it is meaningful to provide an estimate of fair value that differs from the given value of the commitment.

Litigation, Commitments and Contingencies	'
	Note 12. Litigation, Commitments and Contingencies
	Litigation
	In the normal course of business, the Company is a defendant in various legal actions and asserted claims. While the Company and its legal counsel are unable to assess the ultimate outcome of each of these matters with certainty, the Company believes the resolution of these actions, singly or in the aggregate, should not have a material adverse effect on the financial condition, results of operations or cash flows of the Company.
	Commitments and Contingencies
	The Company is a party to financial instruments with off balance sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit, standby letters of credit, and financial guarantees. These instruments involve, to varying degrees, elements of credit and interest rate risk beyond the amount recognized on the balance sheet. The contractual amounts of these instruments reflect the extent of involvement the Company has in particular classes of financial instruments. The Company’s exposure to credit loss in the event of nonperformance by the other party to the financial instrument for commitments to extend credit, standby letters of credit, and financial guarantees is represented by the contractual amount of those instruments. The Company uses the same credit policies in making commitments and conditional obligations as it does for on balance sheet instruments.
	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 Company evaluates each customer’s creditworthiness on a case by case basis. The amount of collateral obtained, if deemed necessary upon extension of credit, is based on management’s credit evaluation of the counterparty. Collateral may include accounts receivable, inventory, plant and equipment, and income producing commercial real estate. Commitments to extend credit, including availability on lines of credit, totaled $209.00 million at September 30, 2013, and $215.77 million at December 31, 2012. Additionally, the Company had gross notional amounts of outstanding commitments related to secondary market mortgage loans of $1.09 million at September 30, 2013, and $14.84 million at December 31, 2012.
	Standby letters of credit and financial guarantees are conditional commitments issued by the Company to guarantee the performance of a customer to a third party. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to customers. To the extent deemed necessary, collateral of varying types and amounts is held to secure customer performance under certain of those letters of credit outstanding. Standby letters of credit and financial guarantees totaled $1.77 million at September 30, 2013, and $6.81 million at December 31, 2012. The Company maintained a reserve for unfunded lending commitments of $326 thousand at September 30, 2013, and December 31, 2012.
	The Company has issued, through the Trust, $15.0 million of trust preferred securities in a private placement. In connection with the issuance of the trust preferred securities, the Company has committed to irrevocably and unconditionally guarantee the following payments or distributions with respect to the trust preferred securities to the holders thereof to the extent that the Trust has not made such payments or distributions and has the funds therefore: (i) accrued and unpaid distributions, (ii) the redemption price, and (iii) upon a dissolution or termination of the Trust, the lesser of the liquidation amount and all accrued and unpaid distributions and the amount of assets of the Trust remaining available for distribution.

Earnings per Common Share	'
	Earnings per Common Share
	Basic earnings per common share is determined by dividing net income available to common shareholders by the weighted average common shares outstanding. Diluted earnings per common share is determined by dividing net income by the weighted average common shares outstanding, including diluted shares for stock options, warrants, contingently issuable shares, and convertible preferred shares. The calculation for basic and diluted earnings per common share follows:
