Summary of Significant Accounting Policies	'
	Note 1.	Summary of Significant Accounting Policies
	Nature of Operations
	Unless the context suggests otherwise, the use of the term “Company” refers to First Community Bancshares, Inc. (“the Company”) and its subsidiaries as a consolidated entity. The Company is a financial holding company headquartered in Bluefield, Virginia that provides banking products and services to individuals and commercial customers through its wholly-owned subsidiary, First Community Bank (the “Bank”), a Virginia-chartered banking institution, from 71 locations. The Bank operates under the trade names First Community Bank in Virginia, West Virginia, and North Carolina and Peoples Community Bank, a Division of First Community Bank, in South Carolina and Tennessee. The Company offers personal and commercial insurance products and services from 9 locations through its wholly-owned subsidiary Greenpoint Insurance Group, Inc. (“Greenpoint”), which is headquartered in High Point, North Carolina. Greenpoint operates under the Greenpoint name and under the trade names First Community Insurance Services (“FCIS”) and Carolina Insurers Associates in North Carolina, Carr &Hyde Insurance and FCIS in Virginia, and FCIS in West Virginia. The Bank offers wealth management services and investment advice through its Trust Division and wholly-owned subsidiary First Community Wealth Management (“FCWM”), a registered investment advisory firm. The Trust Division and FCWM managed $706 million in combined assets as of December 31, 2013. These assets are not assets of the Company, but are managed under various fee-based arrangements as fiduciary or agent. The Company reported consolidated assets of $2.60 billion as of December 31, 2013.
	The Company operates in one business segment, Community Banking, which consists of all operations, including commercial and consumer banking, lending activities, wealth management, and insurance services.
	Principles of Consolidation
	The accounting and reporting policies of the Company conform to generally accepted accounting principles (“GAAP”) in the United States and to predominant practices in the banking industry. The Company’s consolidated financial statements include the accounts of all wholly-owned subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation. Assets held in an agency or fiduciary capacity are not assets of the Company and are not included in the Company’s consolidated balance sheets.
	The Company has investments in certain entities that are considered variable interest entities (“VIEs”) under GAAP. These VIEs include the Company’s trust subsidiary, FCBI Capital Trust (the “Trust”), certain tax credit limited partnerships, and limited liability companies that provide aviation services, insurance brokerage, title insurance, and other related financial services. VIEs are legal entities in which the equity investors do not have sufficient equity at risk for the entity to independently finance its activities or the collective holders do not have the power through voting or similar rights to direct the activities of the entity that most significantly impact its economic performance, the obligation to absorb the expected losses of the entity, or the right to receive expected residual returns of the entity. Consolidation of a VIE is considered appropriate if a reporting entity is the primary beneficiary, the party that has both significant influence and control over the VIE. Management periodically performs a qualitative analysis to determine if the Company is the primary beneficiary of a VIE. This analysis includes review of the VIEs’ capital structures, contractual terms, and primary activities, including the Company’s ability to direct the activities of the VIEs and obligations to absorb losses, or the right to receive benefits, significant to the VIEs. Based on the Company’s analysis for the periods presented in this report, it is not the primary beneficiary of its VIEs. Accordingly, these entities do not meet the criteria for consolidation and, therefore, are reported in other assets in the Company’s consolidated balance sheets. The carrying value and maximum potential loss exposure of VIEs totaled $2.89 million as of December 31, 2013, and $3.04 million as of December 31, 2012.
	Use of Estimates
	In preparing consolidated financial statements in conformity with GAAP, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the balance sheet and reported amounts of revenues and expenses during the reporting period. The Company has identified the items that require the most subjective assumptions or complex judgments: investment securities, the allowance for loan losses, the provision for income taxes, and business combination, including intangible assets.
	Reclassification
	Certain amounts reported in prior years have been reclassified to conform to the current year’s presentation. These reclassifications had no effect on the Company’s results of operations, financial position, or cash flow.
	Cash and Cash Equivalents
	Cash and cash equivalents include cash and due from banks, time deposits with other banks, federal funds sold, and interest-bearing balances on deposit with the Federal Home Loan Bank (“FHLB”) that are available for immediate withdrawal.
	Investment Securities
	Management determines the appropriate classification of securities at the time of purchase. Debt securities that management has the intent and ability to hold to maturity are classified as held-to-maturity securities and carried at amortized cost. Securities not classified as held to maturity, including equity securities with readily determinable fair values, are classified as available-for-sale securities and carried at estimated fair value. Securities classified as available for sale consist of securities management intends to hold for indefinite periods of time, including securities to be used as part of the Company’s asset/liability management strategy and securities that may be sold in response to changes in interest rates, prepayment risk, or other similar factors. Unrealized appreciation or depreciation in fair value above or below amortized cost is included in stockholders’ equity, net of income taxes, under the category of accumulated other comprehensive income (“AOCI”). Gains or losses on the call, maturity, or sale of investment securities are recorded based on the specific identification method. Purchase premiums and discounts are amortized or accreted over the life of a security into interest income.
	The Company performs an extensive quarterly review to determine if impairment exists in the investment portfolio. If a security is deemed impaired, management evaluates the causes of unrealized losses to determine whether the impairment is temporary or other-than-temporary in nature. If a security is determined to be other-than-temporarily impaired, the value of the security is reduced and a corresponding charge to noninterest income is recognized. If the other-than-temporary impairment (“OTTI”) is related to a debt security, the Company determines the amount of the impairment related to the credit loss, which is recognized in noninterest income, and the amount related to all other factors, which is recognized in other comprehensive income (“OCI”).
	Loans Held for Sale
	Loans originated with the intent to sell in the secondary market are classified as held for sale. Loans held for sale consist primarily of one to four family residential loans and are carried at the lower of cost or estimated fair value as determined on an aggregate basis. These long-term, fixed rate loans are sold to investors on a best efforts basis; consequently, the Company does not absorb the interest rate risk involved in these loans. The fair value of loans held for sale is determined by quoted market prices for loans with similar coupon rates and terms.
	The Company enters into interest rate lock commitments (“IRLCs”) with customers on mortgage loans intended to be sold in the secondary market and commitments to sell mortgages. These IRLCs and forward sale loan commitments are recorded at fair value in other assets and liabilities with any changes in fair value recognized in other income. These derivative instruments do not qualify as hedges. The fair value of IRLC derivatives is determined by quoted market prices for loans with similar coupon rates and terms. The fair value of forward sale loan commitments is based on changes in the value of the commitment, principally because of changes in interest rates.
	Loans Held for Investment
	Loans originated with the intent to hold for an indefinite period of time, until maturity, or until pay-off are classified as held for investment. Loans held for investment are carried at the principal amount outstanding, net of unearned income, less any write-downs necessary to reduce individual loans to net realizable value. Loan origination fees, including loan commitment and underwriting fees, are reduced by direct costs associated with loan processing, including salaries, legal review, and appraisal fees. Net deferred loan fees are deferred and amortized over the life of the related loan or commitment period.
	The Company maintains an active and robust problem credit identification system through its ongoing credit review function. When a credit is identified as exhibiting characteristics of weakening, the Company assesses the credit for potential impairment. Loans are considered impaired when, in the opinion of management and based on current information and events, the collection of principal and interest payments due under the contractual terms of the loan agreements are doubtful. The impairment allowances allocated to individual loans, including individual credit relationships, and loan pools, grouped by similar risk characteristics, are reviewed by management on a quarterly basis. Factors considered in determining impairment include, but are not limited to, the borrower’s cash flow and capacity for debt repayment, the valuation of collateral, historical loss percentages, and economic conditions.
	The Company’s Special Assets staff reviews loans $250 thousand and greater on a quarterly basis. Accrual of interest on loans is generally based on the daily amount of principal outstanding. Loans are considered past due when either principal or interest payments become contractually delinquent by 30 or more days. Consumer loans are generally charged off against the allowance for loan losses when the loans become 120 days past due (180 days if secured by residential real estate and 90 days if unsecured). All other loans are charged off against the allowance for loan losses after collection attempts have been exhausted, which generally is within 120 days. It is the Company’s policy to discontinue the accrual of interest, if warranted, on loans based on the payment status, evaluation of the related collateral, and the financial strength of the borrower. The accrual of interest income is normally discontinued when a loan becomes 90 days past due. Management may elect to continue the accrual of interest when the loan is well secured and in process of collection. When interest accruals are discontinued, interest accrued and not collected in the current year is reversed from income, and interest accrued and not collected from prior years is charged to the allowance for loan losses. Interest income realized on impaired loans is recognized upon receipt if the impaired loan is on a nonaccrual basis. Nonaccrual loans may be returned to accrual status if the loan is brought current and follows a period of sustained performance, including six months of regular principal and interest payments. Accrual of interest on impaired loans is generally continued unless the loan becomes delinquent 90 days or more. Recoveries of loans previously charged off are credited to the allowance for loan losses in the period received.
	Loans are considered troubled debt restructurings (“TDRs”) when the Company grants concessions, for legal or economic reasons, to borrowers experiencing financial difficulty that would not otherwise be considered. The Company generally makes concessions in interest rates, loan terms, and/or amortization terms. All TDRs $250 thousand or greater are evaluated for a specific reserve based on either the collateral or net present value method, whichever is most applicable. TDRs under $250 thousand are subject to the reserve calculation for classified loans based primarily on the historical loss rate. At the date of modification, nonaccrual loans are classified as nonaccrual TDRs. TDRs classified as nonperforming at the date of modification 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.
	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 provisions and recoveries of prior loan charge-offs and decreased by loans charged off. The provision is calculated and charged to earnings to bring the allowance to a level that, according to a systematic process of measurement, reflects the amount management estimates is needed to absorb probable losses in 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: the performance of the Company’s loan portfolio, the economy, changes in interest rates, the view of regulatory authorities towards loan classifications, and other factors. While management has allocated the allowance for loan losses to specific loans and general portfolio segments, the entire allowance is available for use against any type of loan loss deemed appropriate by management.
	Management performs quarterly assessments to determine the appropriate level of the allowance for loan losses. The Company’s allowance is segmented into commercial, consumer real estate, and consumer and other loans with each segment divided into classes with similar characteristics, such as the type of loan and collateral. The allowance for loan losses includes specific allocations to significant individual loans and credit relationships and general reserves to the remaining loans that have been deemed impaired. Loans not specifically identified are grouped into pools based on similar risk characteristics. A loan that becomes adversely classified or graded is moved into a group of adversely classified or graded loans with similar risk characteristics for evaluation. Management’s general reserve allocations are based on judgments of qualitative and quantitative factors about macro and micro economic conditions reflected in the loan portfolio and the economy.
	No allowance for loan losses is carried over or established at acquisition for purchased loans acquired in business combinations. A provision for loan losses is recorded for any credit deterioration in purchased performing loans after the acquisition date. Purchased credit impaired (“PCI”) loans are grouped into pools and evaluated separately from the non-PCI portfolio. The Company estimates cash flows to be collected on PCI loans and discounts those cash flows at a market rate of interest. If cash flows for PCI loans are expected to decline, generally a provision for loan losses is charged to earnings, resulting in an increase to the allowance for loan losses. If cash flows for PCI loans are expected to improve, any previously established allowance is first reversed to the extent of prior charges and then interest income is increased using prospective yield adjustment over the remaining life of the loan, or pool of loans. Any provision established for PCI loans covered under the Federal Deposit Insurance Corporation (“FDIC”) loss share agreements is offset by an adjustment to the FDIC indemnification asset to reflect the indemnified portion of the post-acquisition exposure.
	Other Real Estate Owned
	Other real estate owned (“OREO”) and acquired through foreclosure, or other settlement, is carried at the lower of cost or fair value less estimated selling costs. The fair value is generally based on current third-party appraisals. When a property is transferred into OREO, any excess of the loan balance over the net realizable fair value is charged against the allowance for loan losses. Operating expenses, gains, and losses on the sale of OREO are included in other noninterest expense in the Company’s consolidated statements of income after any fair value write-downs are recorded as valuation adjustments.
	Business Combinations
	The Company may engage in business combinations with other companies. These transactions are accounted for using Topic 805 of the Financial Accounting Standards Board’s (“FASB”) Accounting Standards Codification (“ASC”), which requires the use of the acquisition method of accounting. In accordance with the acquisition method of accounting, all identifiable assets acquired, including purchased loans, and liabilities are recorded at fair value. Any excess of the purchase price over the fair value of net assets acquired is recorded as goodwill. In instances where the price of the acquired business is less than the net assets acquired, a gain on the purchase is recorded.
	Management makes significant estimates and judgments in accounting for business combinations. Fair values are assigned based on quoted prices for similar assets, if readily available, or appraisals by qualified independent parties for relevant asset and liability categories. Management must also make estimates for the useful or economic lives of certain acquired assets and liabilities. These lives are used in establishing the amortization and accretion of some intangible assets and liabilities, such as core deposits obtained in the acquisition of commercial banks. Fair values are subject to refinement for up to one year after the closing date of the acquisition as additional information regarding the closing date fair values becomes available. The results of operations of an acquired entity are included in the Company’s consolidated results of operations from the closing date of the merger.
	Purchased loans are recorded using the fair value methodology outlined in Topic 820 of the FASB ASC, exclusive of loss share agreements with the FDIC. The fair value estimates associated with loans include expected prepayments and the amount and timing of expected principal, interest, and other cash flows. No allowance for loan losses is recorded at acquisition for purchased loans because the fair values of the acquired loans incorporate assumptions regarding credit risk.
	When purchased loans exhibit evidence of credit deterioration after the acquisition date, and it is probable at acquisition the Company will not collect all contractually required principal and interest payments, the loans are referred to as PCI loans. PCI loans are accounted for using Topic 310-30 of the FASB ASC, formerly the American Institute of Certified Public Accountants’ Statement of Position 03-3, “Accounting for Certain Loans or Debt Securities Acquired in a Transfer.” PCI loans are initially measured at fair value, which includes estimated future credit losses expected to be incurred over the life of the loans. In accordance with the guidance, the Company aggregates PCI loans that have common risk characteristics into loan pools. The Company has established the following loan pools related to the acquisitions of Peoples Bank of Virginia (“Peoples”) and Waccamaw Bank (“Waccamaw”) for evaluation: Waccamaw commercial, Waccamaw lines of credit, Peoples commercial, Waccamaw serviced home equity lines, Waccamaw residential, Peoples residential, and Waccamaw consumer. Evidence of credit quality deterioration at acquisition may include measures such as nonaccrual status, credit scores, declines in collateral value, current loan to value percentages, and days past due. The Company considers expected prepayments and estimates the amount and timing of expected principal, interest, and other cash flows for each loan or pool of loans identified as credit impaired. If the contractually required payments at acquisition exceed the cash flows expected to be collected, the excess is the non-accretable difference, which is available to absorb credit losses on those loans or pools of loans. If the cash flows expected at acquisition exceed the estimated fair values, the excess is the accretable yield, which is recognized in interest income over the remaining lives of those loans or pools of loans when there is a reasonable expectation about the amount and timing of such cash flows.
	Purchased performing loans are accounting for using the contractual cash flow method of accounting, which results in these loans being recorded at fair value with a credit discount. The fair value discount is accreted as an adjustment to yield over the estimated contractual lives of the loans. Additional information regarding the accounting and valuation of the allowance for loan losses related to purchased loans, intangible assets, and receivables resulting from FDIC-assisted transactions is found in this note of the consolidated financial statements.
	Federal Deposit Insurance Corporation Indemnification Asset
	The FDIC indemnification asset represents the carrying amount of the right to receive payments from the FDIC for losses incurred on specified assets purchased from the FDIC that are covered by loss share agreements. The FDIC indemnification asset is measured separately from related covered assets because it is not contractually embedded in the assets or transferable should the assets be disposed. In accordance with the acquisition method of accounting, the FDIC indemnification asset was recorded at fair value using projected cash flows based on expected reimbursements and applicable loss share percentages as outlined in the loss share agreements with the FDIC. The expected reimbursements did not include reimbursable amounts related to future covered expenditures. The cash flows were discounted to reflect the timing and receipt of reimbursements from the FDIC. The discount is accreted through noninterest income over future periods. The Company regularly reviews the fair value of the FDIC indemnification asset with input from a third-party provider. Post-acquisition adjustments to the indemnification asset are measured on the same basis as the underlying covered assets. Increases in the cash flows of covered loans reduce the FDIC indemnification asset balance, which is recognized as amortization through noninterest income over the shorter of the remaining life of the FDIC indemnification asset or the underlying loans. Decreases in the cash flows of covered loans increase the FDIC indemnification asset balance, which is recognized as accretion through noninterest income. The realization of the FDIC indemnification asset ultimately depends on the performance of the underlying covered assets, the passage of time, and claims paid by the FDIC; therefore, the amount the Company realizes could differ materially from the carrying value.
	Premises and Equipment
	Premises and equipment are stated at cost less accumulated depreciation and amortization. Depreciation and amortization are computed by the straight-line method over the estimated useful lives of the respective assets. Useful lives range from 5 to 10 years for furniture, fixtures, and equipment; 3 to 5 years for software, hardware, and data handling equipment; and 10 to 40 years for buildings and building improvements. Land improvements are amortized over a period of 20 years and leasehold improvements are amortized over the lesser of the term of the respective leases plus the first optional renewal period, when renewal is reasonably assured, or the estimated useful lives of the improvements. The Company leases various properties within its branch network. Leases generally have initial terms of up to 20 years and most contain options to renew with reasonable increases in rent. All leases are accounted for as operating leases. Maintenance and repairs are charged to current operations while improvements that extend the economic useful life of the underlying asset are capitalized. Disposition gains and losses are reflected in current operations.
	Goodwill and Other Intangible Assets
	Intangible assets consist of goodwill, core deposit intangible assets, and other identifiable intangible assets that result from business combinations. Goodwill represents the excess of the purchase price over the fair value of net assets acquired, and it is allocated to the appropriate reporting unit when acquired. The Company maintains two reporting units, Community Banking and Insurance Services. Goodwill is not amortized, but is tested annually in the fourth quarter using a qualitative assessment to determine if it is more likely than not that the fair value of each reporting unit is less than its carrying amount. If the Company concludes that it is more likely than not that the fair value of either reporting unit is less than its carrying amount, the two-step quantitative goodwill impairment test is performed. Step 1 consists of calculating and comparing the fair value of each reporting unit to its carrying amount, including goodwill. If the fair value of a reporting unit is greater than its book value, no goodwill impairment exists. If the carrying amount of a reporting unit is greater than its calculated fair value, goodwill impairment may exist and Step 2 is required to determine the amount of the impairment loss. The Company performed its annual impairment test of goodwill as of October 31, 2013, and determined that qualitatively that it was more likely than not that goodwill was not impaired; therefore, the Step 1 and Step 2 tests were not deemed necessary. Qualitative factors considered in the analysis included macroeconomic conditions, industry and market considerations, overall financial performance, changes in stock price, and the Company’s progress towards stated objectives as compared to prior years. An impairment charge to goodwill and other intangible assets may be required in the future if the Company’s future earnings and cash flows decline or discount rates used in determining fair value increase. No events have occurred after the 2013 analysis to indicate additional impairment.
	Core deposit intangible assets represent the future earnings potential of acquired deposit relationships and are amortized over their estimated remaining useful lives. Other identifiable intangible assets primarily represent the rights arising from contractual arrangements and are amortized using the straight-line method.
	Other Investments
	As a condition of membership in the FHLB and the Federal Reserve Bank (“FRB”), the Company is required to subscribe to a minimum level of stock in the FHLB of Atlanta (“FHLBA”) and FRB of Richmond. These securities are reported in other assets in the Company’s consolidated balance sheets. There is no market for these securities and ownership is restricted; therefore, readily determinable fair values are not available. The Company carries these nonmarketable securities at cost and reviews the FHLB of Atlanta stock quarterly for impairment. The Company believes the FHLB of Atlanta ownership position provides access to relatively inexpensive wholesale and overnight funding. During 2013 and 2012 the FHLBA repurchased excess activity-based stock and paid quarterly cash dividends. Based on publicly available information as of December 31, 2013, the Company believed that its FHLBA stock was not impaired. The investment in FHLBA stock was $10.72 million as of December 31, 2013, and $11.30 million as of December 31, 2012. The investment in FRB of Richmond stock was $5.58 million as of December 31, 2013, and $5.57 million as of December 31, 2012.
	The Company maintains long-term investments in various entities, including the Trust, certain tax credit limited partnerships, and other limited liability companies that provide aviation services, insurance brokerage, title insurance, and other related financial services. These entities are reported in other assets in the Company’s consolidated balance sheets. Investments in entities that the Company has no significant influence or control over, generally ownership interests of less than 20%, are recorded using the cost method of accounting. In accordance with the cost method, these investments do not have readily determinable fair values and dividends received are generally recorded as income. Investments in entities that the Company has the ability to exercise significant influence over but not control, generally ownership interests ranging from 20% to 50%, are recorded using the equity method of accounting. In accordance with the equity method, dividends received generally reduce the carrying amount of the investment, and the investment is adjusted to recognize the Company’s share of the entity’s earnings, losses, and changes in capital, if any. Management believes any future adjustments to equity investments will be immaterial. All long-term investments are reviewed periodically for possible impairment. The carrying value and maximum potential loss of equity investments totaled $786 thousand as of December 31, 2013, and $782 thousand as of December 31, 2012.
	Securities Sold Under Agreements to Repurchase
	Securities sold under agreements to repurchase are generally accounted for as collateralized financing transactions. Securities, generally U.S. government and federal agency securities, pledged as collateral under these arrangements can be sold or repledged only if replaced by the secured party. The fair value of the collateral provided to a third party is continually monitored and additional collateral is provided as appropriate.
	Advertising Expenses
	Advertising costs are generally expensed as incurred. The Company may establish accruals for anticipated advertising expenses in the course of a fiscal year.
	Equity-Based Compensation
	The cost of employee services received in exchange for equity instruments, such as stock options and restricted stock awards, is generally measured at fair value on the grant date. A Black-Scholes model is utilized to estimate the fair value of stock options, while the market price of the Company’s common stock at the date of grant is used as the fair value of restricted stock awards. Compensation cost is recognized over the required service period, generally defined as the vesting period for stock option awards and as the restriction period for restricted stock awards. For awards with graded vesting, compensation cost is recognized on a straight-line basis over the requisite service period for the entire award.
	Income Taxes
	Income tax expense is comprised of the current and deferred tax consequences of events and transactions already recognized. The Company includes interest and penalties related to income tax liabilities in income tax expense. The effective tax rate, income tax expense as a percentage of pre-tax income, may vary significantly from statutory rates due to tax credits and permanent differences. Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the tax bases of assets and liabilities and their carrying amounts for financial reporting purposes. As changes in tax laws or rates are enacted, deferred tax assets and liabilities are adjusted through the provision for income taxes.
	The Company and its subsidiaries’ tax filings for the years ended December 31, 2009 through 2012 are currently open to audit under statutes of limitation by the Internal Revenue Service and various state tax departments.
	Earnings per Common Share
	Basic earnings per common share is calculated by dividing net income available to common shareholders by the weighted average number of common shares outstanding during the period. Diluted earnings per common share includes the dilutive effect of potential common stock that could be issued by the Company. In accordance with the treasury stock method of accounting, potential common stock could be issued for stock options, nonvested restricted stock awards, performance based stock awards, and convertible preferred stock. Diluted earnings per common share is calculated by dividing net income by the weighted average number of common shares outstanding for the period plus the number of dilutive potential common shares. The calculation of diluted earnings per common share excludes potential common shares that have an exercise price greater than the average market value of the Company’s common stock because the effect would be antidilutive.
	The following table presents the calculation of basic and diluted earnings per common share for the periods indicated:
			Year Ended December 31,
	(Amounts in thousands, except share and per share data)		2013		2012		2011

The Company’s Series A Noncumulative Convertible Preferred Stock (“Series A Preferred Stock”) carries a 6% dividend rate. Each share of the Series A Preferred Stock is convertible into 69 shares of the Company’s common stock at any time and mandatorily converts after five years. The Company may redeem the shares at face value after May 20, 2014. The number of Series A Preferred Stock outstanding was 15,251 as of December 31, 2013, 17,421 as of December 31, 2012, and 18,921 shares as of December 31, 2011.
Derivative Instruments
A derivative is an instrument whose value is derived from an underlying instrument or index, such as interest rates, equity security prices, currencies, commodity prices, or credit spreads. Derivatives include futures, forwards, swaps, option contracts, and other financial instruments with similar characteristics. Derivative contracts often involve future commitments to exchange interest payment streams or currencies based on a notional or contractual amount (e.g., interest rate swaps or currency forwards) or to purchase or sell other financial instruments at specified terms on a specified date (e.g., options to buy or sell securities or currencies). The Company enters into derivative transactions principally 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. All derivative instruments are reported at fair value in the balance sheets.
If certain conditions are met, a derivative may be designated as a hedge related to fair value, cash flow, or foreign exposure risk. Changes in the fair value of a derivative instrument vary depending on the intended use of the derivative and the resulting designation. The Company accounts for fair value hedges using the regression analysis method. The hedged item is regressed with the hedging instrument and if the coefficient of determination is at least 0.80 the hedge will be deemed effective. The change in fair value of the hedging derivative and the change in fair value of the hedged exposure are recorded in earnings. Any hedge ineffectiveness is also reflected in current earnings. Changes in the fair value of derivatives not designated as hedging instruments are recognized as a gain or loss in earnings. The Company formally documents any relationships between hedging instruments and hedged items and the risk management objective and strategy for undertaking each hedged transaction. As of December 31, 2013, the Company had one interest rate swap that qualified as a fair value hedging instrument. The Company’s other derivative instruments include various IRLCs and forward sale loan commitments that do not qualify as hedging instruments.
Fair Value Measurements
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 before 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 independent, knowledgeable, able to transact, and 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 principally derived from observable market data.
Level 3 Inputs –		Unobservable inputs for determining the fair values of assets or liabilities when there is little or no 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.
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.
Accounting Standards Updates
In February 2013, the FASB issued Accounting Standards Update (“ASU”) 2013-02, “Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income,” which requires an entity to provide information about the amounts reclassified out of accumulated other comprehensive income. An entity is required to present, either on the face of the statement where net income is presented or in the notes, significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income but only if the amount reclassified is required under GAAP to be reclassified to net income in its entirety in the same reporting period. For other amounts not required under GAAP to be reclassified in their entirety to net income, an entity is required to cross-reference to other disclosures required under GAAP that provide additional detail about these amounts. This update is effective prospectively for interim and annual periods beginning on or after December 15, 2012. The Company adopted the guidance in 2013 and has included the related disclosures in Note 17, “Accumulated Other Comprehensive Income,” to the Consolidated Financial Statements of this report.
In October 2012, the FASB issued ASU 2012-06, “Business Combinations (Topic 805) – Subsequent Accounting for an Indemnification Asset Recognized at the Acquisition Date as a Result of a Government-Assisted Acquisition of a Financial Institution (a consensus of the FASB Emerging Issues Task Force),” to address the diversity in practice about how to subsequently measure an indemnification asset recognized as a result of a government-assisted acquisition of a financial institution. The amendments in ASU 2012-06 require a reporting entity to subsequently account for a change in the measurement of the indemnification asset on the same basis as the change in the assets subject to indemnification. ASU 2012-06 further requires that any amortization of changes in value be limited to the lesser of the term of the indemnification agreement and the remaining life of the indemnified assets. The amendments in ASU 2012-06 are effective prospectively for fiscal years beginning on or after December 15, 2012, and early adoption is permitted. The Company adopted the guidance in 2013 and has recognized negative accretion related to the indemnification asset.

At acquisition, Peoples had total assets of $275.76 million, loans of $184.84 million, and deposits of $232.75 million. The purchase price was $40.28 million, including common stock valued at $26.47 million and cash consideration of $12.26 million. The Company issued 2,157,005 shares of common stock with an estimated fair value of $12.27 per share. Each outstanding share of Peoples was exchanged for $6.08 in cash and 1.07 shares of the Company’s common stock. The Company recorded goodwill of $10.32 million from the acquisition.
	Waccamaw Bank
	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 deposits and certain liabilities of Waccamaw, headquartered in Whiteville, North Carolina. Waccamaw, a full service community bank, operated 16 branches throughout North Carolina and South Carolina. At acquisition, Waccamaw had total assets of $500.64 million, loans of $318.35 million, and deposits of $414.13 million. Under the loss share agreements, the FDIC covers 80% of most loan and foreclosed real estate losses. The Company recorded an indemnification asset of $49.76 million at acquisition representing the present value of estimated losses on covered assets to be reimbursed by the FDIC. The Company recorded goodwill of $10.62 million from the acquisition.
	Insurance Services
	In 2013 the Company issued cash consideration of $150 thousand to purchase one agency. The acquisition terms call for further cash consideration of $253 thousand if certain operating targets are met. The fair value of these payments was booked at acquisition and added $324 thousand of goodwill and other intangibles to the Company’s consolidated balance sheet as of December 31, 2013. In 2011 Greenpoint received cash of $1.58 million from the sale of two agencies.
	Acquisitions that occurred before 2009 call for issuing further cash consideration if certain operating targets are met. If those targets are met, the value of the consideration will be added to the cost of the acquisition. Earn-out payments related to these acquisitions totaled $442 thousand in 2013, $692 thousand in 2012, and $680 thousand in 2011.

The carrying value of securities pledged to secure public deposits and other purposes was $284.77 million as of December 31, 2013, and $292.88 million as of December 31, 2012.
The Company reviews its investment portfolio on a quarterly basis for indications of OTTI. Debt securities not beneficially owned by the Company include securities issued from the U.S. Department of the Treasury (the “Treasury”), municipal securities, and single issue trust preferred securities. For debt securities not beneficially owned, the Company analyzes 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. If the evaluation suggests that the impairment will not be recovered, the Company calculates the present value of the security to determine the amount of OTTI. The security is then written down to its current present value and the Company calculates and records the amount of the loss due to credit factors in earnings through noninterest income and the amount due to other factors in stockholders’ equity through OCI. During 2013 and 2012, the Company incurred no OTTI charges related to debt securities not beneficially owned. Temporary impairment on these securities is primarily related to changes in interest rates, certain disruptions in the credit markets, destabilization in the Eurozone, and other current economic factors.
Debt securities beneficially owned by the Company consist of corporate FDIC securities and mortgage-backed securities (“MBS”). For debt securities beneficially owned, the Company analyzes the cash flows for each applicable security to determine if an adverse change in cash flows expected to be collected has occurred. If the projected value of cash flows at the current reporting date is less than the present value previously projected, and less than the current book value, an adverse change has occurred. The Company then compares the current present value of cash flows to the current net book value to determine the credit-related portion of the OTTI. The credit-related OTTI is recorded in earnings through noninterest income and any remaining noncredit-related OTTI is recorded in stockholders’ equity through OCI. The Company incurred credit-related OTTI charges related to debt securities beneficially owned of $320 thousand in 2013 and $942 thousand in 2012. These charges were related to a non-Agency MBS.
The Company uses a discounted cash flow model for the non-Agency Alt-A residential MBS with the following assumptions: constant voluntary prepayment rate of 2%, a customized constant default rate scenario that assumes approximately 16% of the remaining underlying mortgages will default over the life of the security, and a customized loss severity rate scenario that ramps the loss rate down from 55% to 10% over the course of approximately three years. The following table presents the activity for credit-related losses recognized in earnings on debt securities where a portion of an OTTI was recognized in OCI for the periods indicated:
		Year Ended December 31,
(Amounts in thousands)		2013			2012			2011
Beginning balance (1)		$	7,478		$	6,536		$	4,251

Reduction for securities sold/realized losses			—			—			—
Ending balance		$	7,798		$	7,478		$	6,536
-1	The beginning balance includes credit related losses included in OTTI charges recognized on debt securities in prior periods.
For equity securities, the Company considers its intent to hold or sell the security before recovery, the severity and duration of the decline in fair value of the security below its cost, the financial condition and near-term prospects of the issuer, and whether the decline appears to be related to issuer, general market, or industry conditions to determine if the impairment will be recovered. If the Company deems the impairment other-than-temporary in nature, the security is written down to its current present value and the OTTI loss is charged to earnings. During 2013 and 2012, the Company recognized no OTTI charges related to equity securities.

	Purchased Credit Impaired Loans
	When the fair values of purchased loans are established at acquisition, certain loans are identified as impaired. These PCI loans are aggregated into loan pools that have common risk characteristics. The Company’s loan pools consist of Waccamaw commercial, Waccamaw lines of credit, Peoples commercial, Waccamaw serviced home equity lines, Waccamaw residential, Peoples residential, and Waccamaw consumer. The Company estimates cash flows to be collected on PCI loans and discounts those cash flows at a market rate of interest. The following table presents the carrying and contractual unpaid principal balance of PCI loans, by acquisition, as of the dates indicated:

	Note 5.	Credit Quality
	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 the Company determines that it is probable all principal and interest amounts contractually due will not be collected, the loan is generally deemed to be impaired.
	The following tables present the recorded investment and related information for loans considered to be impaired, excluding PCI loans, as of the periods indicated:

As part of the ongoing monitoring of the Company’s loan portfolio, management tracks certain credit quality indicators that include: 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 analyzes all commercial loan relationships greater than $3.0 million on an annual basis and at various times during the year. In addition, smaller commercial and retail loans are sampled for review during the year. Loan risk ratings may be upgraded or downgraded to reflect current information identified during the loan review process. The Company uses a risk grading matrix to assign a risk grade to each loan in its portfolio. The general characteristics of each risk grade are as follows:
	•		Pass – This grade is assigned to loans with acceptable credit quality and risk. The Company further segments this grade based on borrower characteristics that include: capital strength, earnings stability, liquidity leverage, and industry conditions.
	•		Special Mention – This grade is assigned to loans that require an above average degree of supervision and attention. These loans have the characteristics of an asset with acceptable credit quality and risk; however, adverse economic or financial conditions exist that create potential weaknesses deserving of management’s close attention. If potential weaknesses are not corrected, the prospect of repayment may worsen.
	•		Substandard – This grade is assigned to loans that have well defined weaknesses that may make payment default, or principal exposure, possible. In order to meet repayment terms, these loans will likely be dependent on collateral liquidation, secondary repayment sources, or events outside the normal course of business.
	•		Doubtful – This grade is assigned to loans on nonaccrual status. These loans have the weaknesses inherent in substandard loans; however, the weaknesses are so severe that collection or liquidation in full is extremely unlikely based on current facts, conditions, and values. Due to certain specific pending factors, the amount of loss cannot yet be determined.
	•		Loss – This grade is assigned to loans that will be charged off or charged down when payments, including the timing and value of payments, are determined to be uncertain. This risk grade does not imply that the asset has no recovery or salvage value, but simply means that it is not practical or desirable to defer writing off, either all or a portion of, the loan balance even though partial recovery may be realized in the future.
Losses on covered loans are generally reimbursable by the FDIC at the applicable loss share percentage, 80%; therefore, covered loans are disclosed separately in the following credit quality discussion. PCI loan pools are disaggregated and included in their applicable loan class in the following discussion. In addition, PCI loans are generally not classified as nonaccrual or nonperforming due to the accrual of interest income under the accretion method of accounting.
The following tables present loans held for investment, by internal credit risk grade, as of the periods indicated:

As of December 31, 2013, non-covered special mention and classified loans decreased $42.99 million, or 27.68%, compared to December 31, 2012, which was primarily due to loan workout activity across the portfolio coupled with continued credit improvement. Credit quality also significantly improved in the covered loan portfolio with special mention and classified loans declining $84.15 million, or 66.97%, as of December 31, 2013, compared to December 31, 2012.

The Company may make concessions in interest rates, loan terms and/or amortization terms when restructuring loans for borrowers experiencing financial difficulty. 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. Specific reserves in the allowance for loan losses attributed to TDRs totaled $1.84 million as of December 31, 2013, and $1.87 million as of December 31, 2012. 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 Company recognized interest income on TDRs of $551 thousand in 2013, $640 thousand in 2012, and $411 thousand in 2011.
Loans acquired with credit deterioration, with a discount, are generally not considered a TDR as long as the loan remains in the assigned loan pool. There were no covered loans recorded as TDRs as of December 31, 2013 or 2012. The following table presents loans modified as TDRs, by loan class, segregated by accrual status, as of the dates indicated:

Allowance_for_Loan_Losses

Allowance for Loan Losses	12 Months Ended
	Dec. 31, 2013
Allowance for Loan Losses	'
	Note 6.	Allowance for Loan Losses
	The allowance for loan losses is maintained at a level management deems adequate to absorb probable loan losses inherent in the loan portfolio. The allowance is increased by provisions charges to operations and reduced by net charge-offs. While management utilizes its best judgment and information available, the ultimate adequacy of the allowance is dependent on a variety of factors that may be beyond the Company’s control: the performance of the Company’s loan portfolio, the economy, changes in interest rates, the view of regulatory authorities towards loan classifications, and other factors. These uncertainties may result in a material change to the allowance for loan losses in the near term; however, the amount of the change cannot reasonably be estimated.
	The Company’s allowance is comprised of specific reserves related to loans individually evaluated, including credit relationships, and general reserves related to loans not individually evaluated that are segmented into groups with similar risk characteristics, based on an internal risk grading matrix. General reserve allocations are based on management’s judgments of qualitative and quantitative factors about macro and micro economic conditions reflected within the loan portfolio and the economy. For loans acquired in a business combination, loans identified as credit impaired at the acquisition date are grouped into pools and evaluated separately from the non-PCI portfolio. The Company has aggregated PCI loans into the following pools: Waccamaw commercial, Waccamaw lines of credit, Peoples commercial, Waccamaw serviced home equity lines, Waccamaw residential, Peoples residential, and Waccamaw consumer. Provisions calculated for PCI loans are offset by an adjustment to the FDIC indemnification asset to reflect the indemnified portion, 80%, of the post-acquisition exposure. While allocations are made to specific loans, various portfolio segments, and loan pools, the allowance for loan losses is available for use against any loan loss management deems appropriate. As of December 31, 2013, management believed the allowance was adequate to absorb probable loan losses inherent in the loan portfolio.
	The following table presents the aggregate activity in the allowance for loan losses in the periods indicated:

	Goodwill
	Goodwill represents the excess of the purchase price over the fair value of net assets acquired. Goodwill is allocated to the appropriate reporting unit when acquired, if applicable. Before 2009, the cash consideration for meeting certain operating targets, under the agreement terms, was added to goodwill when paid. Beginning in 2009, the estimated future value of the cash consideration is recognized as goodwill at the acquisition date. As of December 31, 2013, the total potential cash consideration remaining to be paid in connection with acquisitions that occurred before 2009 was $353 thousand, which is allocated to the Insurance Services reporting unit. The Company analyzed the carrying value of goodwill as of October 31, 2013, and determined that no impairment charge was necessary.

	Total borrowings		$	300,396	$	313,553
	Short-term borrowings consist of federal funds purchased and retail repurchase agreements, which are typically collateralized with agency MBSs. The weighted average rate of federal funds purchased was 0.36% as of December 31, 2013. The weighted average rate of retail repurchase agreements was 0.38% as of December 31, 2013, and 0.57% as of December 31, 2012.
	Long-term borrowings consist of wholesale repurchase agreements; FHLB borrowings, including fixed rate credit and convertible and callable advances; and other obligations. The weighted average contractual rate of wholesale repurchase agreements was 3.71% as of December 31, 2013, and 3.34% as of December 31, 2012. As of December 31, 2013, the weighted average contractual maturity of wholesale repurchase agreements was 4.08 years. The weighted average contractual rate of FHLB borrowings was 4.12% as of December 31, 2013, and 3.86% as of December 31, 2012. As of December 31, 2013, the weighted average contractual maturity of FHLB borrowings was 4.57 years.

	FHLB callable advances may be redeemed by the FHLB at quarterly intervals after various lockout periods that could substantially shorten the lives of the advances. If called, the advance may be paid in full or converted into another FHLB credit product. Prepayment of an advance may result in substantial penalties based on the differential between the contractual note and current advance rate for similar maturities. FHLB advances were secured by qualifying loans that totaled $1.13 billion as of December 31, 2013, and $998.14 million as of December 31, 2012. Unused borrowing capacity with the FHLB was $324.34 million as of December 31, 2013. In 2013, the Company prepaid $8.15 million in wholesale repurchase agreements and $11.47 million in FHLB borrowings resulting in a $296 thousand gain.
	Subordinated debt consists of junior subordinated debentures (“Debentures”) of $15.46 million that were issued by the Company in October 2003 to the Trust. The Debentures had an interest rate of three-month LIBOR plus 2.95%. 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. 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. The preferred securities issued by the Trust are not included in the Company’s consolidated balance sheets; however, these securities qualify as Tier 1 capital for regulatory purposes, subject to guidelines issued by the Board of Governors of the Federal Reserve System (the “Federal Reserve”). The Federal Reserve’s quantitative limits did not prevent the Company from including all $15.46 million in trust preferred securities outstanding in Tier 1 capital as of December 31, 2013 and 2012.

Derivative Instruments and Hedging Activities	12 Months Ended

Derivative Instruments and Hedging Activities	'
	Note 12.	Derivative Instruments and Hedging Activities
	The Company primarily uses derivative instruments 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. 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. These derivative instruments may consist of interest rate swaps, floors, caps, collars, futures, forward contracts, and written and purchased options. Derivative instruments are subject to counterparty credit risk due to the possibility that the Company will incur a loss because a counterparty, which may be a bank, a broker-dealer or a customer, 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.
	As of December 31, 2013, the Company’s derivative instruments consisted of IRLCs, forward sale loan commitments, and interest rate swaps. Generally, derivative instruments help the Company manage exposure to market risk and 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.
	IRLCs and forward sale loan commitments. In the normal course of business, the Company enters into interest rate lock commitments (“IRLCs”) with customers on mortgage loans intended to be sold in the secondary market and commitments to sell those originated mortgage loans. 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 date we issue the commitment 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 declines when interest rates increase and rise when interest rates decrease. The fair values of the Company’s IRLCs and forward sale loan commitments are recorded at fair value as a component of other assets and other liabilities in the consolidated balance sheets. These derivatives do not qualify as hedging instruments; therefore, changes in fair value are recorded in earnings.
	Interest rate swaps. The Company uses interest rate swap contracts to modify its exposure to interest rate risk caused by changes in the London InterBank Offered Rate (“LIBOR”) curve in relation to certain designated fixed rate loans. These instruments are used to convert these fixed rate loans to an effective floating rate. If the LIBOR rate falls below the loan’s stated fixed rate for a given period, the Company will owe the floating rate payer the notional amount times the difference between LIBOR and the stated fixed rate. If LIBOR is above the stated rate for a given period, the Company will receive payments based on the notional amount times the difference between LIBOR and the stated fixed rate. The Company’s interest rate swaps qualify as fair value hedging instruments; therefore, changes in the fair value of the derivative and of the hedged item attributable to the hedged risk are recognized in earnings in the same period.
	In October 2013, the Company entered into a ten-year, $3.50 million notional interest rate swap agreement that was accounted for as a fair value hedge. The swap and loan hedged by the swap are recorded at fair value. The hedge was effective as of December 31, 2013.

	Note 13.	Employee Benefit Plans
	Employee Stock Ownership and Savings Plan
	The Company maintains the Employee Stock Ownership and Savings Plan (“KSOP”). Coverage under the plan is provided to all employees who meet minimum eligibility requirements. The KSOP held 499,075 shares of the Company’s common stock as of December 31, 2013, 561,551 shares as of December 31, 2012, and 588,656 shares as of December 31, 2011.
	Employer Stock Fund
	The Company made annual contributions to the stock feature within the KSOP at the discretion of the Board of Directors until December 31, 2006, when the plan was frozen to future contributions. Substantially all plan assets are invested in the Company’s common stock. All KSOP contributions beginning in 2007 have been made to the employee savings feature of the plan.
	Employee Savings Plan
	The Company provides a 401(k) savings feature within the KSOP. The Company makes matching contributions to employee deferrals at levels determined by the Board of Directors on an annual basis. The cost of the Company’s 100% matching contributions to qualified deferrals under the 401(k) savings component of the KSOP was $1.61 million in 2013, $1.27 million in 2012, and $1.34 million in 2011. In 2013 and 2011, all matching contributions were made in the Company’s common stock. In 2012, matching contributions were made in cash and the Company’s common stock.
	Employee Welfare Plan
	The Company provides various medical, dental, vision, life, accidental death and dismemberment, and long-term disability insurance benefits to all full-time employees who elect coverage under this program. The health plan is managed by a third-party administrator. Monthly employer and employee contributions are made to a tax-exempt employee benefits trust where the third-party administrator processes and pays claims. Stop-loss insurance coverage limits the Company’s risk of loss to $100 thousand for individual claims and $3.98 million aggregate claims. Expenses related to the health plan were $3.02 million in 2013, $2.25 million in 2012, and $3.49 million in 2011.
	Deferred Compensation Plan
	The Company maintains deferred compensation agreements with certain current and former officers that provide benefit payments, over various periods, commencing at retirement or death. Accrued benefits are based on the present values of expected payments and estimated life expectancies and totaled $455 thousand as of December 31, 2013, and $459 thousand as of December 31, 2012. Expenses related to the deferred compensation plan were $60 thousand in each of the three years ended December 31, 2013.
	Supplemental Executive Retention Plan
	The Company maintains the Supplemental Executive Retention Plan (the “SERP”) for key members of senior management. The domestic noncontributory, nonqualified SERP provides for a defined benefit, at normal retirement age, targeted at 35% of the participant’s projected final average compensation, subject to a defined maximum annual benefit. Benefits under the SERP generally become payable at age 62. The SERP is an unfunded plan; accordingly, there are no plan assets.

Equity-Based Compensation	'
	Note 14.	Equity-Based Compensation
	The Company maintains equity-based compensation plans to promote the long-term success of the Company by encouraging officers, employees, directors, and other individuals performing services for the Company to focus on critical long-range objectives. The Company’s equity-based compensation plans include the 2012 Omnibus Equity Compensation Plan (“2012 Plan”), 2004 Omnibus Stock Option Plan, 2001 Director’s Option Plan, 1999 Stock Option Plan, and various other option plans. As of December 31, 2013, the 2012 Plan was the only plan available for the issuance of future grants. All plans before the 2012 Plan are frozen and no new grants may be issued; however, any options or awards unexercised and outstanding under those plans remain in effect in accordance with their respective terms.
	The 2012 Plan made available up to 600,000 shares for potential grants of incentive stock options, nonqualified stock options, performance awards, restricted stock, restricted stock units, stock appreciation rights, bonus stock, and stock awards. Options granted pursuant to the 2012 Plan shall state the period of time the grant may be exercised, not to exceed more than ten years from the date granted. The Company’s Compensation and Retirement Committee shall determine the vesting period for each grant; however, if no vesting period is specified the vesting shall occur in 25% increments on the first four anniversaries of the grant date.
	The following table presents the pre-tax compensation expense and excess tax benefit recognized in earnings for all equity-based compensation plans in the periods indicated:
			Year Ended December 31,

	Pre-tax compensation expense		$	574	$	206	$	98
	Excess tax benefit			9		6		5
	Stock Options
	The fair value of stock options is estimated at the date of grant using the Black-Scholes-Merton valuation model with the following assumptions: expected volatility is based on the weekly historical volatility of the Company’s common stock price over the expected term of the option; the expected term is generally calculated using the shortcut method; the risk-free interest rate is based on the Treasury yield curve on the grant date with a term comparable to the grant; and the dividend yield is based on the Company’s dividend yield using the most recent dividend rate paid per share and trading price of the Company’s common stock.
	The following table presents the assumptions used to estimate the fair values of stock options at the date of grant in the periods indicated. No stock options were granted in 2013 or 2012.

	The aggregate intrinsic value of options exercised was $22 thousand as of December 31, 2013, $16 thousand as of December 31, 2012, and $13 thousand as of December 31, 2011.
	As of December 31, 2013, unrecognized compensation expense related to nonvested stock options was $61 thousand, which is expected to be recognized over a weighted average period of 0.44 years. The actual compensation cost recognized will differ from this estimate due to a number of items, including new grants and changes in estimated forfeitures.
	Restricted Stock Awards
	Restricted stock awards represent shares issued upon grant that are restricted and generally use a three-year vesting schedule from the grant date. The fair value of restricted stock awards is calculated using the Company’s common stock price on the grant date. The following table presents restricted stock activity under the equity-based compensation plans in the period indicated:
			Shares		Weighted Average
					Grant-Date
					Fair  Value
	Nonvested, January 1, 2013			18,950	$	12.67

	Canceled			13,000		12.68
	Nonvested, December 31, 2013			2,600	$	15.09
	As of December 31, 2013, unrecognized compensation cost related to nonvested restricted stock awards was $23 thousand, which is expected to be recognized over a weighted average period of 0.87 years. The actual compensation cost recognized will differ from this estimate due to a number of items, including new awards granted and changes in estimated forfeitures.
	Performance Stock Awards
	Performance stock awards represent shares potentially issuable in the future. In 2013, the Company awarded 80,872 shares with a three-year performance period. Approximately 48% of each award vested on the grant date and the remaining shares vest in three equal installments, subject to the annual performance requirement and the recipient’s continued employment on the applicable vesting date. The performance requirement is based on an annual three-year average minimum growth rate in earnings per share. The fair value of performance stock awards is calculated using the Company’s stock price on the grant date. The following table presents performance stock activity under the 2012 Plan in the period indicated:
			Shares		Weighted Average
					Grant-Date
					Fair Value
	Nonvested, January 1, 2013			—	$	—
	Granted			80,872		15.75
	Vested			39,084		15.75
	Canceled			4,854		15.56
	Nonvested, December 31, 2013			36,934	$	15.78
	As of December 31, 2013, unrecognized compensation cost related to nonvested performance stock awards was $216 thousand, which is expected to be recognized over a weighted average period of 1.08 years. The actual compensation cost recognized will differ from this estimate due to a number of items, including new awards granted and changes in estimated forfeitures.

Fair_Value

Fair Value	12 Months Ended

Fair Value	'
	Note 18.	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 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 presented in the following discussion. The fair value hierarchy prioritizes the inputs used in measuring fair value as follows:
		•		Level 1 – Observable, unadjusted quoted prices in active markets
		•		Level 2 – Inputs other than quoted prices included in Level 1 that are directly or indirectly observable for the asset or liability
		•		Level 3 – Unobservable inputs with little or no market activity that require the Company to use reasonable inputs and assumptions
	The Company uses fair value measurements to record adjustments to certain financial assets and liabilities on a recurring basis. Additionally, the Company may be required to record certain assets at fair value on a nonrecurring basis in specific circumstances, such as evidence of impairment. Methodologies used to determine fair value may be highly subjective and judgmental in nature, such as cash flow estimates, risk characteristics, credit quality measurements, and interest rates; therefore, valuations may not be precise. Since fair values are estimated as of a specific date, the amounts actually realized or paid on the settlement or maturity of these instruments may be significantly different from estimates. See Note 1, “Summary of Significant Accounting Policies,” to the Consolidated Financial Statements of this report.
	Assets and Liabilities Reported at Fair Value on a Recurring Basis
	Available-for-Sale Securities. Securities available for sale are reported at fair value on a recurring basis. The fair value of Level 1 securities is based on quoted market prices in active markets, if available. The Company also uses Level 1 inputs to value equity securities that are traded in active markets. If quoted market prices are not available, fair values are measured utilizing independent valuation techniques of identical or similar securities for which significant assumptions are primarily derived from or corroborated by observable market data. Level 2 securities use fair value measurements from independent pricing services obtained by the Company. These fair value measurements consider observable data that may include dealer quotes, market spreads, cash flows, the Treasury yield curve, live trading levels, trade execution data, market consensus prepayment speeds, credit information, and bond terms and conditions. The Company’s Level 2 securities include U.S. Treasury securities, single issue trust preferred securities, corporate securities, MBS, and certain equity securities that are not actively traded. Securities are based on Level 3 inputs 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. For Level 3 securities, the Company obtains the cash flow of specific securities from third parties that use modeling software to determine cash flows based on market participant data and knowledge of the structures of each individual security. The fair value of Level 3 securities are determined by applying appropriate market observable discount rates to the cash flow derived from third-party models. Discount rates are developed by determining credit spreads above a benchmark rate, such as LIBOR, and adding premiums for illiquidity, which are based on a comparison of initial issuance spread to LIBOR versus a financial sector curve for recently issued debt to LIBOR. Securities with 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.
	Deferred Compensation Assets and Liabilities. Securities held for trading purposes are recorded at fair value on a recurring basis and included in other assets in the consolidated balance sheets. These securities include assets related to employee deferred compensation plans, which are generally invested in Level 1 equity securities. The liability associated with these deferred compensation plans are carried at the fair value of the obligation to the employee, which corresponds to the fair value of the invested assets.
	Derivative Assets and Liabilities. Derivatives are recorded at fair value on a recurring basis. The Company obtains dealer quotes, Level 2 inputs, based on observable data to value derivatives.
	The following tables summarize financial assets and liabilities recorded at fair value on a recurring basis, segregated by the level of valuation inputs in the fair value hierarchy, as of the dates indicated:

	There were no changes in valuation techniques during the years ended December 31, 2013 or 2012. If the Company determines that a valuation technique change is necessary, the change is assumed to have occurred at the end of the respective reporting period. In addition, there were no transfers in to or out of Level 3 of the fair value hierarchy during the years ended December 31, 2013 or 2012.
	Assets Measured at Fair Value on a Nonrecurring Basis
	Impaired Loans. Impaired loans are recorded at fair value on a nonrecurring basis when repayment is expected solely from the sale of the loan’s collateral. Fair value is based on appraised value adjusted for customized discounting criteria, Level 3 inputs.
	The Company maintains an active and robust problem credit identification system. The impairment review includes obtaining third-party collateral valuations to assist management in identifying potential credit impairment and determining the amount of impairment to record. The Company’s Special Assets staff assumes the management and monitoring of all loans determined to be impaired. Internal collateral valuations are generally performed within two to four weeks of identifying the initial potential impairment. The internal valuation compares the original appraisal to current local real estate market conditions and considers experience and expected liquidation costs. A third-party valuation is typically received within thirty to forty-five days of completing the internal valuation. When a third-party valuation is received, it is reviewed for reasonableness. Once the valuation is reviewed and accepted, discounts are applied to fair market value, based on, but not limited to, our historical liquidation experience for like collateral, resulting in an estimated net realizable value. The estimated net realizable value is compared to the outstanding loan balance to determine the appropriate amount of specific impairment reserve.
	Specific reserves are generally recorded for impaired loans while third-party valuations are in process and for impaired loans that continue to make some form of payment. While waiting to receive the third-party appraisal, the Company regularly reviews the relationship to identify any potential adverse developments and begins the tasks necessary to gain control of the collateral and prepare it for liquidation, including, but not limited to, engagement of counsel, inspection of collateral, and continued communication with the borrower, if appropriate. Generally, the only difference between the current appraised value, less liquidation costs, and the carrying amount of the loan, less the specific reserve, is any downward adjustment to the appraised value that the Company deems appropriate, such as the costs to sell the property and a deflator for the devaluation of property when banks are the sellers. Impaired loans that do not meet the aforementioned criteria and do not have a specific reserve have typically been written down through partial charge-offs to net realizable value. Based on prior experience, the Company rarely returns loans to performing status after they have been partially charged off. Credits identified as impaired move quickly through the process towards ultimate resolution except in cases involving bankruptcy and various state judicial processes, which may extend the time for ultimate resolution.
	Other Real Estate Owned. OREO is recorded at fair value on a nonrecurring basis using Level 3 inputs. The Company calculates the fair value of OREO from current or prior appraisals that have been adjusted for valuation declines, estimated selling costs, and other proprietary qualitative adjustments that are deemed necessary.
	Goodwill. Goodwill is recorded at fair value on a nonrecurring basis when impairment has occurred. The fair value of the Company’s reporting units use Level 3 inputs based on discounted cash flow and market multiple models.
	The following tables summarize assets measured at fair value on a nonrecurring basis, segregated by the level of valuation inputs in the fair value hierarchy, in the periods indicated:

Fair Value of Financial Instruments
The Company uses various methodologies and assumptions to estimate the fair value of certain financial instruments. A description of the valuation methodologies used for instruments not previously discussed is as follows:
Cash and Cash Equivalents. Cash and cash equivalents are reported at their carrying amount, which is considered a reasonable estimate due to the short-term nature of these instruments.
Held-to-Maturity Securities. Securities held to maturity are reported at fair value using quoted market prices or dealer quotes.
Loans Held for Sale. Loans held for sale are reported at the lower of cost or estimated fair value. Estimated fair value is based on the market price of similar loans.
Loans Held for Investment. Loans held for investment are reported at fair value using discounted future cash flows that apply current interest rates for loans with similar terms and borrower credit quality.
FDIC Indemnification Asset. The FDIC indemnification asset is reported at fair value using discounted future cash flows that apply current discount rates.
Accrued Interest Receivable/Payable. Accrued interest receivable/payable is reported at their carrying amount, which is considered a reasonable estimate due to the short-term nature of these instruments.
Deposits and Securities Sold Under Agreements to Repurchase. Deposits without a stated maturity, such as demand, interest-bearing demand, and savings, are reported at their carrying amount, the amount payable on demand as of the reporting date, which is considered a reasonable estimate of fair value. Deposits and repurchase agreements with fixed maturities and rates are reported at fair value using discounted future cash flows that apply interest rates currently available in the market for instruments with similar characteristics and maturities.
FHLB and Other Indebtedness. FHLB and other indebtedness is reported at fair value using discounted future cash flows that apply interest rates currently available to the Company for borrowings with similar characteristics and maturities. Trust preferred obligations are reported at fair value using current credit spreads in the market for similar issues.
Off-Balance Sheet Instruments. The Company believes that fair values of unfunded commitments to extend credit, standby letters of credit, and financial guarantees are not meaningful; therefore, off-balance sheet instruments are not addressed in the fair value disclosures. Due to the uncertainty and difficulty in assessing the likelihood and timing of advancing available proceeds, the lack of an established market for these instruments, and the diversity in fee structures, the Company believes it is not feasible or practicable to accurately disclose the fair values of off-balance sheet instruments. For additional information regarding the unfunded, contractual value of off-balance sheet financial instruments see Note 20, “Litigation, Commitments and Contingencies,” to the Consolidated Financial Statements of this report.

Litigation, Commitments and Contingencies	'
	Note 20.	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 in the balance sheets. The contractual amounts of these instruments reflect the extent of involvement the Company has in particular classes of financial instruments. If the other party to a financial instrument does not perform, the Company’s credit loss exposure is the same as the contractual amount of the instrument. 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, is based on management’s credit evaluation of the customer. Collateral may include accounts receivable, inventory, property, plant and equipment, and income producing commercial properties. Commitments to extend credit also include outstanding commitments related to mortgage loans that are sold on a best efforts basis into the secondary loan market. The Company maintains a reserve for the risk inherent in unfunded lending commitments, which is included in other liabilities in the consolidated balance sheets.
	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 credit to customers. The amount of collateral obtained, if deemed necessary, to secure the customer’s performance under certain letters of credit is based on management’s credit evaluation of the customer.
	The following table presents the Company’s off-balance sheet financial instruments as of the dates indicated:
			December 31,
			2013		2012
	(Amounts in thousands)
	Commitments to extend credit		$	216,179	$	215,770

	Reserve for unfunded commitments		$	326	$	326
	The Company issued $15.46 million of trust preferred securities in a private placement through the Trust. In connection with the issuance, 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.

Regulatory Capital Requirements and Restrictions	'
	Note 21.	Regulatory Capital Requirements and Restrictions
	The Company and the Bank are subject to various regulatory capital requirements administered by state and federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the Company’s consolidated financial statements. Under the capital adequacy guidelines and the regulatory framework for prompt corrective action, which applies only to the Bank, the Bank must meet specific capital guidelines that involve quantitative measures of the entity’s assets, liabilities, and certain off-balance sheet items as calculated under regulatory accounting practices. The Bank’s capital amounts and classifications are also subject to qualitative judgments by the regulators about components, risk weightings, and other factors. Quantitative measures established by regulation to ensure capital adequacy require the Company and the Bank to maintain minimum amounts and ratios for total and Tier 1 capital, as defined in the regulations, to risk-weighted assets, as defined, and of Tier 1 capital, as defined, to average assets, as defined.
	To be categorized as well capitalized, the Bank must maintain minimum total capital to risk-weighted assets, Tier 1 capital to risk-weighted assets, and Tier 1 capital to average assets (leverage) ratios established by banking regulators. As of December 31, 2013, the Company and the Bank continued to meet all capital adequacy requirements. As of December 31, 2013, the most recent notifications from regulators continued to categorize the Bank as well capitalized under the regulatory framework for prompt corrective action. Management believes there have been no conditions or events since those notifications that would change the Bank’s classification. The following table presents the Company’s and the Bank’s capital ratios as of the dates indicated:

	The primary source of funds for dividends paid by the Company to shareholders is dividends received from the Bank, which are subject to banking regulation restrictions. Approval by regulatory authorities is required to declare dividends if the dividends are to be paid in something other than cash, if the cumulative dividend payment exceeds the net retained income of the current year to date plus the retained net income of the preceding two years, or if payment of the dividend would cause the Bank to become undercapitalized.
	The Bank issues mortgages insured by the U.S. Department of Housing and Urban Development (“HUD”) as a HUD-approved Title II Supervised Mortgagee. A Title II Supervised Mortgagee must maintain an adjusted minimum net worth of $1 million. Not complying with this minimum net worth requirement may result in penalties, such as the revocation of the Bank’s license to issue HUD insured mortgages, which may have a material adverse effect on the Company’s financial condition and results of operations. The Bank’s adjusted net worth was $201.92 million as of December 31, 2013, and $205.54 million as of December 31, 2012, which significantly exceeds minimum net worth requirements.

Summary_of_Significant_Account1

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2013
Principles of Consolidation	'
	Principles of Consolidation
	The accounting and reporting policies of the Company conform to generally accepted accounting principles (“GAAP”) in the United States and to predominant practices in the banking industry. The Company’s consolidated financial statements include the accounts of all wholly-owned subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation. Assets held in an agency or fiduciary capacity are not assets of the Company and are not included in the Company’s consolidated balance sheets.
	The Company has investments in certain entities that are considered variable interest entities (“VIEs”) under GAAP. These VIEs include the Company’s trust subsidiary, FCBI Capital Trust (the “Trust”), certain tax credit limited partnerships, and limited liability companies that provide aviation services, insurance brokerage, title insurance, and other related financial services. VIEs are legal entities in which the equity investors do not have sufficient equity at risk for the entity to independently finance its activities or the collective holders do not have the power through voting or similar rights to direct the activities of the entity that most significantly impact its economic performance, the obligation to absorb the expected losses of the entity, or the right to receive expected residual returns of the entity. Consolidation of a VIE is considered appropriate if a reporting entity is the primary beneficiary, the party that has both significant influence and control over the VIE. Management periodically performs a qualitative analysis to determine if the Company is the primary beneficiary of a VIE. This analysis includes review of the VIEs’ capital structures, contractual terms, and primary activities, including the Company’s ability to direct the activities of the VIEs and obligations to absorb losses, or the right to receive benefits, significant to the VIEs. Based on the Company’s analysis for the periods presented in this report, it is not the primary beneficiary of its VIEs. Accordingly, these entities do not meet the criteria for consolidation and, therefore, are reported in other assets in the Company’s consolidated balance sheets. The carrying value and maximum potential loss exposure of VIEs totaled $2.89 million as of December 31, 2013, and $3.04 million as of December 31, 2012.
Use of Estimates	'
	Use of Estimates
	In preparing consolidated financial statements in conformity with GAAP, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the balance sheet and reported amounts of revenues and expenses during the reporting period. The Company has identified the items that require the most subjective assumptions or complex judgments: investment securities, the allowance for loan losses, the provision for income taxes, and business combination, including intangible assets.
Reclassification	'
	Reclassification
	Certain amounts reported in prior years have been reclassified to conform to the current year’s presentation. These reclassifications had no effect on the Company’s results of operations, financial position, or cash flow.
Cash and Cash Equivalents	'
	Cash and Cash Equivalents
	Cash and cash equivalents include cash and due from banks, time deposits with other banks, federal funds sold, and interest-bearing balances on deposit with the Federal Home Loan Bank (“FHLB”) that are available for immediate withdrawal.
Investment Securities	'
	Investment Securities
	Management determines the appropriate classification of securities at the time of purchase. Debt securities that management has the intent and ability to hold to maturity are classified as held-to-maturity securities and carried at amortized cost. Securities not classified as held to maturity, including equity securities with readily determinable fair values, are classified as available-for-sale securities and carried at estimated fair value. Securities classified as available for sale consist of securities management intends to hold for indefinite periods of time, including securities to be used as part of the Company’s asset/liability management strategy and securities that may be sold in response to changes in interest rates, prepayment risk, or other similar factors. Unrealized appreciation or depreciation in fair value above or below amortized cost is included in stockholders’ equity, net of income taxes, under the category of accumulated other comprehensive income (“AOCI”). Gains or losses on the call, maturity, or sale of investment securities are recorded based on the specific identification method. Purchase premiums and discounts are amortized or accreted over the life of a security into interest income.
	The Company performs an extensive quarterly review to determine if impairment exists in the investment portfolio. If a security is deemed impaired, management evaluates the causes of unrealized losses to determine whether the impairment is temporary or other-than-temporary in nature. If a security is determined to be other-than-temporarily impaired, the value of the security is reduced and a corresponding charge to noninterest income is recognized. If the other-than-temporary impairment (“OTTI”) is related to a debt security, the Company determines the amount of the impairment related to the credit loss, which is recognized in noninterest income, and the amount related to all other factors, which is recognized in other comprehensive income (“OCI”).
Loans Held for Sale	'
	Loans Held for Sale
	Loans originated with the intent to sell in the secondary market are classified as held for sale. Loans held for sale consist primarily of one to four family residential loans and are carried at the lower of cost or estimated fair value as determined on an aggregate basis. These long-term, fixed rate loans are sold to investors on a best efforts basis; consequently, the Company does not absorb the interest rate risk involved in these loans. The fair value of loans held for sale is determined by quoted market prices for loans with similar coupon rates and terms.
	The Company enters into interest rate lock commitments (“IRLCs”) with customers on mortgage loans intended to be sold in the secondary market and commitments to sell mortgages. These IRLCs and forward sale loan commitments are recorded at fair value in other assets and liabilities with any changes in fair value recognized in other income. These derivative instruments do not qualify as hedges. The fair value of IRLC derivatives is determined by quoted market prices for loans with similar coupon rates and terms. The fair value of forward sale loan commitments is based on changes in the value of the commitment, principally because of changes in interest rates.
Loans Held for Investment	'
	Loans Held for Investment
	Loans originated with the intent to hold for an indefinite period of time, until maturity, or until pay-off are classified as held for investment. Loans held for investment are carried at the principal amount outstanding, net of unearned income, less any write-downs necessary to reduce individual loans to net realizable value. Loan origination fees, including loan commitment and underwriting fees, are reduced by direct costs associated with loan processing, including salaries, legal review, and appraisal fees. Net deferred loan fees are deferred and amortized over the life of the related loan or commitment period.
	The Company maintains an active and robust problem credit identification system through its ongoing credit review function. When a credit is identified as exhibiting characteristics of weakening, the Company assesses the credit for potential impairment. Loans are considered impaired when, in the opinion of management and based on current information and events, the collection of principal and interest payments due under the contractual terms of the loan agreements are doubtful. The impairment allowances allocated to individual loans, including individual credit relationships, and loan pools, grouped by similar risk characteristics, are reviewed by management on a quarterly basis. Factors considered in determining impairment include, but are not limited to, the borrower’s cash flow and capacity for debt repayment, the valuation of collateral, historical loss percentages, and economic conditions.
	The Company’s Special Assets staff reviews loans $250 thousand and greater on a quarterly basis. Accrual of interest on loans is generally based on the daily amount of principal outstanding. Loans are considered past due when either principal or interest payments become contractually delinquent by 30 or more days. Consumer loans are generally charged off against the allowance for loan losses when the loans become 120 days past due (180 days if secured by residential real estate and 90 days if unsecured). All other loans are charged off against the allowance for loan losses after collection attempts have been exhausted, which generally is within 120 days. It is the Company’s policy to discontinue the accrual of interest, if warranted, on loans based on the payment status, evaluation of the related collateral, and the financial strength of the borrower. The accrual of interest income is normally discontinued when a loan becomes 90 days past due. Management may elect to continue the accrual of interest when the loan is well secured and in process of collection. When interest accruals are discontinued, interest accrued and not collected in the current year is reversed from income, and interest accrued and not collected from prior years is charged to the allowance for loan losses. Interest income realized on impaired loans is recognized upon receipt if the impaired loan is on a nonaccrual basis. Nonaccrual loans may be returned to accrual status if the loan is brought current and follows a period of sustained performance, including six months of regular principal and interest payments. Accrual of interest on impaired loans is generally continued unless the loan becomes delinquent 90 days or more. Recoveries of loans previously charged off are credited to the allowance for loan losses in the period received.
	Loans are considered troubled debt restructurings (“TDRs”) when the Company grants concessions, for legal or economic reasons, to borrowers experiencing financial difficulty that would not otherwise be considered. The Company generally makes concessions in interest rates, loan terms, and/or amortization terms. All TDRs $250 thousand or greater are evaluated for a specific reserve based on either the collateral or net present value method, whichever is most applicable. TDRs under $250 thousand are subject to the reserve calculation for classified loans based primarily on the historical loss rate. At the date of modification, nonaccrual loans are classified as nonaccrual TDRs. TDRs classified as nonperforming at the date of modification 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.
Allowance for Loan Losses	'
	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 provisions and recoveries of prior loan charge-offs and decreased by loans charged off. The provision is calculated and charged to earnings to bring the allowance to a level that, according to a systematic process of measurement, reflects the amount management estimates is needed to absorb probable losses in 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: the performance of the Company’s loan portfolio, the economy, changes in interest rates, the view of regulatory authorities towards loan classifications, and other factors. While management has allocated the allowance for loan losses to specific loans and general portfolio segments, the entire allowance is available for use against any type of loan loss deemed appropriate by management.
	Management performs quarterly assessments to determine the appropriate level of the allowance for loan losses. The Company’s allowance is segmented into commercial, consumer real estate, and consumer and other loans with each segment divided into classes with similar characteristics, such as the type of loan and collateral. The allowance for loan losses includes specific allocations to significant individual loans and credit relationships and general reserves to the remaining loans that have been deemed impaired. Loans not specifically identified are grouped into pools based on similar risk characteristics. A loan that becomes adversely classified or graded is moved into a group of adversely classified or graded loans with similar risk characteristics for evaluation. Management’s general reserve allocations are based on judgments of qualitative and quantitative factors about macro and micro economic conditions reflected in the loan portfolio and the economy.
	No allowance for loan losses is carried over or established at acquisition for purchased loans acquired in business combinations. A provision for loan losses is recorded for any credit deterioration in purchased performing loans after the acquisition date. Purchased credit impaired (“PCI”) loans are grouped into pools and evaluated separately from the non-PCI portfolio. The Company estimates cash flows to be collected on PCI loans and discounts those cash flows at a market rate of interest. If cash flows for PCI loans are expected to decline, generally a provision for loan losses is charged to earnings, resulting in an increase to the allowance for loan losses. If cash flows for PCI loans are expected to improve, any previously established allowance is first reversed to the extent of prior charges and then interest income is increased using prospective yield adjustment over the remaining life of the loan, or pool of loans. Any provision established for PCI loans covered under the Federal Deposit Insurance Corporation (“FDIC”) loss share agreements is offset by an adjustment to the FDIC indemnification asset to reflect the indemnified portion of the post-acquisition exposure.
Other Real Estate Owned	'
	Other Real Estate Owned
	Other real estate owned (“OREO”) and acquired through foreclosure, or other settlement, is carried at the lower of cost or fair value less estimated selling costs. The fair value is generally based on current third-party appraisals. When a property is transferred into OREO, any excess of the loan balance over the net realizable fair value is charged against the allowance for loan losses. Operating expenses, gains, and losses on the sale of OREO are included in other noninterest expense in the Company’s consolidated statements of income after any fair value write-downs are recorded as valuation adjustments.
Business Combinations	'
	Business Combinations
	The Company may engage in business combinations with other companies. These transactions are accounted for using Topic 805 of the Financial Accounting Standards Board’s (“FASB”) Accounting Standards Codification (“ASC”), which requires the use of the acquisition method of accounting. In accordance with the acquisition method of accounting, all identifiable assets acquired, including purchased loans, and liabilities are recorded at fair value. Any excess of the purchase price over the fair value of net assets acquired is recorded as goodwill. In instances where the price of the acquired business is less than the net assets acquired, a gain on the purchase is recorded.
	Management makes significant estimates and judgments in accounting for business combinations. Fair values are assigned based on quoted prices for similar assets, if readily available, or appraisals by qualified independent parties for relevant asset and liability categories. Management must also make estimates for the useful or economic lives of certain acquired assets and liabilities. These lives are used in establishing the amortization and accretion of some intangible assets and liabilities, such as core deposits obtained in the acquisition of commercial banks. Fair values are subject to refinement for up to one year after the closing date of the acquisition as additional information regarding the closing date fair values becomes available. The results of operations of an acquired entity are included in the Company’s consolidated results of operations from the closing date of the merger.
	Purchased loans are recorded using the fair value methodology outlined in Topic 820 of the FASB ASC, exclusive of loss share agreements with the FDIC. The fair value estimates associated with loans include expected prepayments and the amount and timing of expected principal, interest, and other cash flows. No allowance for loan losses is recorded at acquisition for purchased loans because the fair values of the acquired loans incorporate assumptions regarding credit risk.
	When purchased loans exhibit evidence of credit deterioration after the acquisition date, and it is probable at acquisition the Company will not collect all contractually required principal and interest payments, the loans are referred to as PCI loans. PCI loans are accounted for using Topic 310-30 of the FASB ASC, formerly the American Institute of Certified Public Accountants’ Statement of Position 03-3, “Accounting for Certain Loans or Debt Securities Acquired in a Transfer.” PCI loans are initially measured at fair value, which includes estimated future credit losses expected to be incurred over the life of the loans. In accordance with the guidance, the Company aggregates PCI loans that have common risk characteristics into loan pools. The Company has established the following loan pools related to the acquisitions of Peoples Bank of Virginia (“Peoples”) and Waccamaw Bank (“Waccamaw”) for evaluation: Waccamaw commercial, Waccamaw lines of credit, Peoples commercial, Waccamaw serviced home equity lines, Waccamaw residential, Peoples residential, and Waccamaw consumer. Evidence of credit quality deterioration at acquisition may include measures such as nonaccrual status, credit scores, declines in collateral value, current loan to value percentages, and days past due. The Company considers expected prepayments and estimates the amount and timing of expected principal, interest, and other cash flows for each loan or pool of loans identified as credit impaired. If the contractually required payments at acquisition exceed the cash flows expected to be collected, the excess is the non-accretable difference, which is available to absorb credit losses on those loans or pools of loans. If the cash flows expected at acquisition exceed the estimated fair values, the excess is the accretable yield, which is recognized in interest income over the remaining lives of those loans or pools of loans when there is a reasonable expectation about the amount and timing of such cash flows.
	Purchased performing loans are accounting for using the contractual cash flow method of accounting, which results in these loans being recorded at fair value with a credit discount. The fair value discount is accreted as an adjustment to yield over the estimated contractual lives of the loans. Additional information regarding the accounting and valuation of the allowance for loan losses related to purchased loans, intangible assets, and receivables resulting from FDIC-assisted transactions is found in this note of the consolidated financial statements.
Federal Deposit Insurance Corporation Indemnification Asset	'
	Federal Deposit Insurance Corporation Indemnification Asset
	The FDIC indemnification asset represents the carrying amount of the right to receive payments from the FDIC for losses incurred on specified assets purchased from the FDIC that are covered by loss share agreements. The FDIC indemnification asset is measured separately from related covered assets because it is not contractually embedded in the assets or transferable should the assets be disposed. In accordance with the acquisition method of accounting, the FDIC indemnification asset was recorded at fair value using projected cash flows based on expected reimbursements and applicable loss share percentages as outlined in the loss share agreements with the FDIC. The expected reimbursements did not include reimbursable amounts related to future covered expenditures. The cash flows were discounted to reflect the timing and receipt of reimbursements from the FDIC. The discount is accreted through noninterest income over future periods. The Company regularly reviews the fair value of the FDIC indemnification asset with input from a third-party provider. Post-acquisition adjustments to the indemnification asset are measured on the same basis as the underlying covered assets. Increases in the cash flows of covered loans reduce the FDIC indemnification asset balance, which is recognized as amortization through noninterest income over the shorter of the remaining life of the FDIC indemnification asset or the underlying loans. Decreases in the cash flows of covered loans increase the FDIC indemnification asset balance, which is recognized as accretion through noninterest income. The realization of the FDIC indemnification asset ultimately depends on the performance of the underlying covered assets, the passage of time, and claims paid by the FDIC; therefore, the amount the Company realizes could differ materially from the carrying value.
Premises and Equipment	'
	Premises and Equipment
	Premises and equipment are stated at cost less accumulated depreciation and amortization. Depreciation and amortization are computed by the straight-line method over the estimated useful lives of the respective assets. Useful lives range from 5 to 10 years for furniture, fixtures, and equipment; 3 to 5 years for software, hardware, and data handling equipment; and 10 to 40 years for buildings and building improvements. Land improvements are amortized over a period of 20 years and leasehold improvements are amortized over the lesser of the term of the respective leases plus the first optional renewal period, when renewal is reasonably assured, or the estimated useful lives of the improvements. The Company leases various properties within its branch network. Leases generally have initial terms of up to 20 years and most contain options to renew with reasonable increases in rent. All leases are accounted for as operating leases. Maintenance and repairs are charged to current operations while improvements that extend the economic useful life of the underlying asset are capitalized. Disposition gains and losses are reflected in current operations.
Goodwill and Other Intangible Assets	'
	Goodwill and Other Intangible Assets
	Intangible assets consist of goodwill, core deposit intangible assets, and other identifiable intangible assets that result from business combinations. Goodwill represents the excess of the purchase price over the fair value of net assets acquired, and it is allocated to the appropriate reporting unit when acquired. The Company maintains two reporting units, Community Banking and Insurance Services. Goodwill is not amortized, but is tested annually in the fourth quarter using a qualitative assessment to determine if it is more likely than not that the fair value of each reporting unit is less than its carrying amount. If the Company concludes that it is more likely than not that the fair value of either reporting unit is less than its carrying amount, the two-step quantitative goodwill impairment test is performed. Step 1 consists of calculating and comparing the fair value of each reporting unit to its carrying amount, including goodwill. If the fair value of a reporting unit is greater than its book value, no goodwill impairment exists. If the carrying amount of a reporting unit is greater than its calculated fair value, goodwill impairment may exist and Step 2 is required to determine the amount of the impairment loss. The Company performed its annual impairment test of goodwill as of October 31, 2013, and determined that qualitatively that it was more likely than not that goodwill was not impaired; therefore, the Step 1 and Step 2 tests were not deemed necessary. Qualitative factors considered in the analysis included macroeconomic conditions, industry and market considerations, overall financial performance, changes in stock price, and the Company’s progress towards stated objectives as compared to prior years. An impairment charge to goodwill and other intangible assets may be required in the future if the Company’s future earnings and cash flows decline or discount rates used in determining fair value increase. No events have occurred after the 2013 analysis to indicate additional impairment.
	Core deposit intangible assets represent the future earnings potential of acquired deposit relationships and are amortized over their estimated remaining useful lives. Other identifiable intangible assets primarily represent the rights arising from contractual arrangements and are amortized using the straight-line method.
Other Investments	'
	Other Investments
	As a condition of membership in the FHLB and the Federal Reserve Bank (“FRB”), the Company is required to subscribe to a minimum level of stock in the FHLB of Atlanta (“FHLBA”) and FRB of Richmond. These securities are reported in other assets in the Company’s consolidated balance sheets. There is no market for these securities and ownership is restricted; therefore, readily determinable fair values are not available. The Company carries these nonmarketable securities at cost and reviews the FHLB of Atlanta stock quarterly for impairment. The Company believes the FHLB of Atlanta ownership position provides access to relatively inexpensive wholesale and overnight funding. During 2013 and 2012 the FHLBA repurchased excess activity-based stock and paid quarterly cash dividends. Based on publicly available information as of December 31, 2013, the Company believed that its FHLBA stock was not impaired. The investment in FHLBA stock was $10.72 million as of December 31, 2013, and $11.30 million as of December 31, 2012. The investment in FRB of Richmond stock was $5.58 million as of December 31, 2013, and $5.57 million as of December 31, 2012.
	The Company maintains long-term investments in various entities, including the Trust, certain tax credit limited partnerships, and other limited liability companies that provide aviation services, insurance brokerage, title insurance, and other related financial services. These entities are reported in other assets in the Company’s consolidated balance sheets. Investments in entities that the Company has no significant influence or control over, generally ownership interests of less than 20%, are recorded using the cost method of accounting. In accordance with the cost method, these investments do not have readily determinable fair values and dividends received are generally recorded as income. Investments in entities that the Company has the ability to exercise significant influence over but not control, generally ownership interests ranging from 20% to 50%, are recorded using the equity method of accounting. In accordance with the equity method, dividends received generally reduce the carrying amount of the investment, and the investment is adjusted to recognize the Company’s share of the entity’s earnings, losses, and changes in capital, if any. Management believes any future adjustments to equity investments will be immaterial. All long-term investments are reviewed periodically for possible impairment. The carrying value and maximum potential loss of equity investments totaled $786 thousand as of December 31, 2013, and $782 thousand as of December 31, 2012.
Securities Sold Under Agreements to Repurchase	'
	Securities Sold Under Agreements to Repurchase
	Securities sold under agreements to repurchase are generally accounted for as collateralized financing transactions. Securities, generally U.S. government and federal agency securities, pledged as collateral under these arrangements can be sold or repledged only if replaced by the secured party. The fair value of the collateral provided to a third party is continually monitored and additional collateral is provided as appropriate.
Advertising Expenses	'
	Advertising Expenses
	Advertising costs are generally expensed as incurred. The Company may establish accruals for anticipated advertising expenses in the course of a fiscal year.
Equity-Based Compensation	'
	Equity-Based Compensation
	The cost of employee services received in exchange for equity instruments, such as stock options and restricted stock awards, is generally measured at fair value on the grant date. A Black-Scholes model is utilized to estimate the fair value of stock options, while the market price of the Company’s common stock at the date of grant is used as the fair value of restricted stock awards. Compensation cost is recognized over the required service period, generally defined as the vesting period for stock option awards and as the restriction period for restricted stock awards. For awards with graded vesting, compensation cost is recognized on a straight-line basis over the requisite service period for the entire award.
Income Taxes	'
	Income Taxes
	Income tax expense is comprised of the current and deferred tax consequences of events and transactions already recognized. The Company includes interest and penalties related to income tax liabilities in income tax expense. The effective tax rate, income tax expense as a percentage of pre-tax income, may vary significantly from statutory rates due to tax credits and permanent differences. Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the tax bases of assets and liabilities and their carrying amounts for financial reporting purposes. As changes in tax laws or rates are enacted, deferred tax assets and liabilities are adjusted through the provision for income taxes.
	The Company and its subsidiaries’ tax filings for the years ended December 31, 2009 through 2012 are currently open to audit under statutes of limitation by the Internal Revenue Service and various state tax departments.
Earnings per Common Share	'
	Earnings per Common Share
	Basic earnings per common share is calculated by dividing net income available to common shareholders by the weighted average number of common shares outstanding during the period. Diluted earnings per common share includes the dilutive effect of potential common stock that could be issued by the Company. In accordance with the treasury stock method of accounting, potential common stock could be issued for stock options, nonvested restricted stock awards, performance based stock awards, and convertible preferred stock. Diluted earnings per common share is calculated by dividing net income by the weighted average number of common shares outstanding for the period plus the number of dilutive potential common shares. The calculation of diluted earnings per common share excludes potential common shares that have an exercise price greater than the average market value of the Company’s common stock because the effect would be antidilutive.
	The following table presents the calculation of basic and diluted earnings per common share for the periods indicated:
		Year Ended December 31,
	(Amounts in thousands, except share and per share data)	2013		2012		2011

	Restricted stock		271		—		2,343
	Total potential antidilutive shares		317,691		420,802		395,476
	The Company’s Series A Noncumulative Convertible Preferred Stock (“Series A Preferred Stock”) carries a 6% dividend rate. Each share of the Series A Preferred Stock is convertible into 69 shares of the Company’s common stock at any time and mandatorily converts after five years. The Company may redeem the shares at face value after May 20, 2014. The number of Series A Preferred Stock outstanding was 15,251 as of December 31, 2013, 17,421 as of December 31, 2012, and 18,921 shares as of December 31, 2011.
Derivative Instruments	'
	Derivative Instruments
	A derivative is an instrument whose value is derived from an underlying instrument or index, such as interest rates, equity security prices, currencies, commodity prices, or credit spreads. Derivatives include futures, forwards, swaps, option contracts, and other financial instruments with similar characteristics. Derivative contracts often involve future commitments to exchange interest payment streams or currencies based on a notional or contractual amount (e.g., interest rate swaps or currency forwards) or to purchase or sell other financial instruments at specified terms on a specified date (e.g., options to buy or sell securities or currencies). The Company enters into derivative transactions principally 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. All derivative instruments are reported at fair value in the balance sheets.
	If certain conditions are met, a derivative may be designated as a hedge related to fair value, cash flow, or foreign exposure risk. Changes in the fair value of a derivative instrument vary depending on the intended use of the derivative and the resulting designation. The Company accounts for fair value hedges using the regression analysis method. The hedged item is regressed with the hedging instrument and if the coefficient of determination is at least 0.80 the hedge will be deemed effective. The change in fair value of the hedging derivative and the change in fair value of the hedged exposure are recorded in earnings. Any hedge ineffectiveness is also reflected in current earnings. Changes in the fair value of derivatives not designated as hedging instruments are recognized as a gain or loss in earnings. The Company formally documents any relationships between hedging instruments and hedged items and the risk management objective and strategy for undertaking each hedged transaction. As of December 31, 2013, the Company had one interest rate swap that qualified as a fair value hedging instrument. The Company’s other derivative instruments include various IRLCs and forward sale loan commitments that do not qualify as hedging instruments.
Fair Value Measurements	'
	Fair Value Measurements
	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 before 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 independent, knowledgeable, able to transact, and 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 principally derived from observable market data.
	Level 3 Inputs –	Unobservable inputs for determining the fair values of assets or liabilities when there is little or no 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.
	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.
Accounting Standards Updates	'
	Accounting Standards Updates
	In February 2013, the FASB issued Accounting Standards Update (“ASU”) 2013-02, “Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income,” which requires an entity to provide information about the amounts reclassified out of accumulated other comprehensive income. An entity is required to present, either on the face of the statement where net income is presented or in the notes, significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income but only if the amount reclassified is required under GAAP to be reclassified to net income in its entirety in the same reporting period. For other amounts not required under GAAP to be reclassified in their entirety to net income, an entity is required to cross-reference to other disclosures required under GAAP that provide additional detail about these amounts. This update is effective prospectively for interim and annual periods beginning on or after December 15, 2012. The Company adopted the guidance in 2013 and has included the related disclosures in Note 17, “Accumulated Other Comprehensive Income,” to the Consolidated Financial Statements of this report.
	In October 2012, the FASB issued ASU 2012-06, “Business Combinations (Topic 805) – Subsequent Accounting for an Indemnification Asset Recognized at the Acquisition Date as a Result of a Government-Assisted Acquisition of a Financial Institution (a consensus of the FASB Emerging Issues Task Force),” to address the diversity in practice about how to subsequently measure an indemnification asset recognized as a result of a government-assisted acquisition of a financial institution. The amendments in ASU 2012-06 require a reporting entity to subsequently account for a change in the measurement of the indemnification asset on the same basis as the change in the assets subject to indemnification. ASU 2012-06 further requires that any amortization of changes in value be limited to the lesser of the term of the indemnification agreement and the remaining life of the indemnified assets. The amendments in ASU 2012-06 are effective prospectively for fiscal years beginning on or after December 15, 2012, and early adoption is permitted. The Company adopted the guidance in 2013 and has recognized negative accretion related to the indemnification asset.
