Accounting Policies [Abstract]	'
Nature of Banking Activities and Significant Accounting Policies	'
	1	NATURE OF BANKING ACTIVITIES AND SIGNIFICANT ACCOUNTING POLICIES
	Organization
	Community Bankers Trust Corporation (the “Company”) is a bank holding company that was incorporated under Delaware law on April 6, 2005. The Company is headquartered in Glen Allen, Virginia and is the holding company for Essex Bank (the “Bank”), a Virginia state bank with 19 full-service offices in Virginia and Maryland as of November 12, 2013. The Bank also operates two loan production offices.
	The Bank engages in a general commercial banking business and provides a wide range of financial services primarily to individuals and small businesses, including individual and commercial demand and time deposit accounts, commercial and industrial loans, consumer and small business loans, real estate and mortgage loans, investment services, on-line and mobile banking products, and safe deposit box facilities. Thirteen offices are located in Virginia, from the Chesapeake Bay to just west of Richmond and six are located in Maryland along the Baltimore-Washington corridor.
	Prior to November 8, 2013, the Bank also had four full-service offices in Georgia. The Bank sold those offices and related deposits to Community and Southern Bank on November 8, 2013. See Note 13 for additional information.
	Financial Statements
	The consolidated statements presented include accounts of the Company and the Bank, its wholly-owned subsidiary. All material intercompany balances and transactions have been eliminated. The statements should be read in conjunction with the Company’s consolidated financial statements and the accompanying notes to consolidated financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2012. The accounting and reporting policies of the Company conform to generally accepted accounting principles (GAAP) and to the general practices within the banking industry. The interim financial statements have not been audited; however, in the opinion of management, all adjustments, consisting of normal accruals, were made that are necessary to present fairly the balance sheet of the Company as of September 30, 2013, changes in stockholders’ equity and cash flows for the nine months ended September 30, 2013, and the income statement and statement of comprehensive income for the three and nine months ended September 30, 2013. Results for the nine month period ended September 30, 2013 are not necessarily indicative of the results that may be expected for the year ended December 31, 2013.
	The financial information contained within the statements is, to a significant extent, financial information that is based on measures of the financial effects of transactions and events that have already occurred. A variety of factors could affect the ultimate value that is obtained when either earning income, recognizing an expense, recovering an asset or relieving a liability. The Company uses historical loss factors as one factor in determining the inherent loss that may be present in its loan portfolio. Actual losses could differ significantly from the historical factors that the Company uses. In addition, GAAP itself may change from one previously acceptable method to another method. Although the economics of the Company’s transactions would be the same, the timing of events that would impact its transactions could change.
	Certain reclassifications have been made to prior period balances to conform to the current period presentation.
	In preparing these financial statements, the Company has evaluated subsequent events and transactions for potential recognition or disclosure through the date the financial statements were issued.
	Recent Accounting Pronouncements
	In July 2013, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2013-11, Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists (a consensus of the FASB Emerging Issues Task Force). U.S. GAAP does not include explicit guidance on the financial statement presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. The amendments in this ASU state that an unrecognized tax benefit, or a portion of an unrecognized tax benefit, should be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward, except as follows. To the extent a net operating loss carryforward, a similar tax loss, or a tax credit carryforward is not available at the reporting date under the tax law of the applicable jurisdiction to settle any additional income taxes that would result from the disallowance of a tax position or the tax law of the applicable jurisdiction does not require the entity to use, and the entity does not intend to use, the deferred tax asset for such purpose, the unrecognized tax benefit should be presented in the financial statements as a liability and should not be combined with deferred tax assets.
	The amendments in this ASU are effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. Early adoption is permitted. Retrospective application is permitted. The Company currently presents these tax items in accordance with this guidance; therefore, no changes are necessary for adoption.
	In February 2013, the FASB issued ASU No. 2013-02, Comprehensive Income (Topic 220): Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income, to improve the transparency of reporting these reclassifications. Other comprehensive income includes gains and losses that are initially excluded from net income for an accounting period. Those gains and losses are later reclassified out of accumulated other comprehensive income into net income. The amendments in this ASU do not change the current requirements for reporting net income or other comprehensive income in financial statements. All of the information that this ASU requires is already required to be disclosed elsewhere in the financial statements under U.S. GAAP. The new amendments will require an organization to:

		•	Present (either on the face of the statement where net income is presented or in the notes) the effects on the line items of net income of significant amounts reclassified out of accumulated other comprehensive income - but only if the item reclassified is required under U.S. GAAP to be reclassified to net income in its entirety in the same reporting period.

		•	Cross-reference to other disclosures currently required under U.S. GAAP for other reclassification items, which are not required under U.S. GAAP to be reclassified directly to net income in their entirety in the same reporting period.
	The amendments apply to all public and private companies that report items of other comprehensive income. Public companies are required to comply with these amendments for all reporting periods (interim and annual). The amendments are effective for reporting periods beginning after December 15, 2012. Early adoption is permitted. The Company adopted this guidance with no material impact on its consolidated financial statements.

Proceeds from sales of securities available for sale were $12.2 million and $29.8 million during the three months ended September 30, 2013 and 2012, respectively, and $66.8 million and $139.6 million during the nine months ended September 30, 2013 and 2012, respectively. Gains and losses on the sale of securities are determined using the specific identification method. Gross realized gains and losses on sales of securities available for sale during the periods were as follows (dollars in thousands):




		Three Months Ended						Nine Months Ended

In estimating other than temporary impairments (OTTI) losses, management considers the length of time and the extent to which the fair value has been less than cost, the financial condition and short-term prospects for the issuer, and the intent and ability of management to hold its investment for a period of time to allow a recovery in fair value. There were no investments held that had OTTI losses for the three and nine months ended September 30, 2013 and 2012.



The fair value and gross unrealized losses for securities available for sale, segregated by the length of time that individual securities have been in a continuous gross unrealized loss position, at September 30, 2013 and December 31, 2012 were as follows (dollars in thousands):

The unrealized losses in the investment portfolio at September 30, 2013 and December 31, 2012 are generally a result of market fluctuations that occur daily. The unrealized losses are from 234 securities at September 30, 2013. Of those, 229 are investment grade, U.S. government agency guarantees, or the full faith and credit of local municipalities throughout the United States. Five investment grade corporate obligations comprise the remaining securities with unrealized losses at September 30, 2013. The Company considers the reason for impairment, length of impairment and ability to hold until the full value is recovered in determining if the impairment is temporary in nature. Based on this analysis, the Company has determined these impairments to be temporary in nature. The Company does not intend to sell and it is more likely than not that the Company will not be required to sell these securities until they recover in value.

Market prices are affected by conditions beyond the control of the Company. Investment decisions are made by the management group of the Company and reflect the overall liquidity and strategic asset/liability objectives of the Company. Management analyzes the securities portfolio frequently and manages the portfolio to provide an overall positive impact to the Company’s income statement and balance sheet.

Securities with amortized costs of $73.4 million and $111.7 million at September 30, 2013 and December 31, 2012, respectively, were pledged to secure deposits and for other purposes required or permitted by law. At each of September 30, 2013 and December 31, 2012, there were no securities purchased from a single issuer, other than U.S. Treasury issue and other U.S. Government agencies that comprised more than 10% of the consolidated shareholders’ equity.

	The Company’s non-covered loans at September 30, 2013 and December 31, 2012 were comprised of the following (dollars in thousands):

	The Company held $39.7 million and $40.9 million in balances of loans guaranteed by the United States Department of Agriculture (USDA), which are included in various categories in the table above, at September 30, 2013 and December 31, 2012, respectively. As these loans are 100% guaranteed by the USDA, no loan loss provision is required. These loan balances included an unamortized purchase premium of $2.8 million and $3.4 million at September 30, 2013 and December 31, 2012, respectively. Unamortized purchase premium is recognized as an adjustment of the related loan yield using the interest method.

	At September 30, 2013 and December 31, 2012, the Company’s allowance for credit losses was comprised of the following: (i) specific valuation allowances calculated in accordance with FASB ASC 310, Receivables, (ii) general valuation allowances calculated in accordance with FASB ASC 450, Contingencies, based on economic conditions and other qualitative risk factors, and (iii) historical valuation allowances calculated using historical loan loss experience. Management identified loans subject to impairment in accordance with ASC 310.

	At September 30, 2013 and December 31, 2012, a portion of the construction and land development loans presented above contained interest reserve provisions. The Company follows standard industry practice to include interest reserves and capitalized interest in a construction loan. This practice recognizes interest as an additional cost of the project and, as a result, requires the borrower to put additional equity into the project. In order to monitor the project throughout its life to make sure the property is moving along as planned to ensure appropriateness of continuing to capitalize interest, the Company coordinates an independent property inspection in connection with each disbursement of loan funds. Until completion, there is generally no cash flow from which to make the interest payment. The Company does not advance additional interest reserves to keep a loan from becoming nonperforming.

	There were no significant amounts of interest reserves recognized as interest income on construction loans with interest reserves for each of the three and nine months ended September 30, 2013 and 2012. Nonperforming construction loans with interest reserves were $4.1 million at each of September 30, 2013 and December 31, 2012.

	Interest income on nonaccrual loans, if recognized, is recorded using the cash basis method of accounting. There were no significant amounts recognized during either of the three and nine months ended September 30, 2013 and 2012. For the three months ended September 30, 2013 and 2012, estimated interest income of $259,000 and $473,000, respectively, would have been recorded if all such loans had been accruing interest according to their original contractual terms. For the nine months ended September 30, 2013 and 2012, estimated interest income of $774,000 and $1.2 million, respectively, would have been recorded if all such loans had been accruing interest according to their original contractual terms.

(1)	The category “Individually Evaluated for Impairment” includes loans individually evaluated for impairment and determined not to be impaired. These loans totalled $11.0 million and $19.0 million at September 30, 2013 and December 31, 2012, respectively. The allowance for loans losses allocated to these loans was $308,000 and $714,000 at September 30, 2013 and December 31, 2012, respectively.
Non-covered loans are monitored for credit quality on a recurring basis. These credit quality indicators are defined as follows:

Pass - A pass loan is not adversely classified, as it does not display any of the characteristics for adverse classification. This category includes purchased loans that are 100% guaranteed by U.S. Government agencies of $39.7 million and $40.9 million at September 30, 2013 and December 31, 2012, respectively.

Special Mention - A special mention loan has potential weaknesses that deserve management’s close attention. If left uncorrected, such potential weaknesses may result in deterioration of the repayment prospects or collateral position at some future date. Special mention loans are not adversely classified and do not warrant adverse classification.

Substandard - A substandard loan is inadequately protected by the current net worth and paying capacity of the obligor or of the collateral pledged, if any. Loans classified as substandard generally have a well defined weakness, or weaknesses, that jeopardize the liquidation of the debt. These loans are characterized by the distinct possibility of loss if the deficiencies are not corrected.

Doubtful - A doubtful loan has all the weaknesses inherent in a loan classified as substandard with the added characteristics that the weaknesses make collection or liquidation in full highly questionable and improbable, on the basis of currently existing facts, conditions, and values.

In accordance with FASB ASU 2011-02, Receivables (Topic 310): A Creditor’s Determination of Whether a Restructuring is a Troubled Debt Restructuring, the Company assesses all loan modifications to determine whether they are considered troubled debt restructurings (TDRs) under the guidance. During the three months ended September 30 2013, there were no loans modified, that were considered to be TDRs. During the nine months ended September 30, 2013, the Company modified one residential 1-4 family loan that was considered to be a TDR. The Company extended the term and lowered the interest rate for this loan, which had a pre- and post-modification balance of $174,000.



During the three months ended September 30, 2012, the Company modified two loans that were considered to be TDRs. The Company extended the terms for one of these loans and lowered the interest rate for one of these loans. The following table presents information relating to loans modified as TDRs during the three months ended September 30, 2012 (dollars in thousands):

A loan is considered to be in default if it is 90 days or more past due. There was one TDR that had been restructured during the previous 12 months that resulted in default during the three and nine months ended September 30, 2013. This residential 1-4 family loan had a recorded investment of $173,000.

There were two TDRs that had been restructured during the previous 12 months that resulted in default during each of the three and nine months ended September 30, 2012. The following table presents information relating to TDRs that resulted in default during the three and nine months ended September 30, 2012 (dollars in thousands):

In the determination of the allowance for loan losses, management considers TDRs and subsequent defaults in these restructures by reviewing for impairment in accordance with FASB ASC 310-10-35, Receivables, Subsequent Measurement.



On September 30, 2013, the Company entered into an agreement to sell $25.1 million of loans in the Georgia branches to Pinnacle Bank at a $250,000 premium (see Note 13). These loans were classified as loans held for sale at September 30, 2013.

At September 30, 2013, the Company had 1-4 family mortgages in the amount of $149.2 million pledged as collateral to the Federal Home Loan Bank for a total borrowing capacity of $92.4 million.

	4	LOANS COVERED BY FDIC SHARED-LOSS AGREEMENTS (COVERED LOANS) AND RELATED ALLOWANCE FOR LOAN LOSSES
	On January 30, 2009, the Company entered into a Purchase and Assumption Agreement with the Federal Deposit Insurance Corporation (FDIC) to assume all of the deposits and certain other liabilities and acquire substantially all assets of Suburban Federal Savings Bank (SFSB). The Company is applying the provisions of FASB ASC 310-30, Loans and Debt Securities Acquired with Deteriorated Credit Quality, to all loans acquired in the SFSB transaction (the “covered loans”). Of the total $198.3 million in loans acquired, $49.1 million met the criteria of FASB ASC 310-30. These loans, consisting mainly of construction loans, were deemed impaired at the acquisition date. The remaining $149.1 million of loans acquired, comprised mainly of residential 1-4 family, were analogized to meet the criteria of FASB ASC 310-30. Analysis of this portfolio revealed that SFSB utilized weak underwriting and documentation standards, which led the Company to believe that significant losses were probable given the economic environment at the time.
	As of September 30, 2013 and December 31, 2012, the outstanding contractual balance of the covered loans was $123.8 million and $137.2 million, respectively. The carrying amount, by loan type, as of these dates is as follows (dollars in thousands):

	5	FDIC AGREEMENTS AND FDIC INDEMNIFICATION ASSET
	On January 30, 2009, the Company entered into a Purchase and Assumption Agreement with the FDIC to assume all of the deposits and certain other liabilities and acquire substantially all assets of SFSB. Under the shared-loss agreements that are part of that agreement, the FDIC will reimburse the Bank for 80% of losses arising from covered loans and foreclosed real estate assets, on the first $118 million in losses on such covered loans and foreclosed real estate assets, and for 95% of losses on covered loans and foreclosed real estate assets thereafter. Under the shared-loss agreements, a “loss” on a covered loan or foreclosed real estate is defined generally as a realized loss incurred through a permitted disposition, foreclosure, short-sale or restructuring of the covered loan or foreclosed real estate. The reimbursements for losses on single family one-to-four residential mortgage assets are to be made quarterly through March 2019, and the reimbursements for losses on other covered assets are to be made quarterly through March 2014. The shared-loss agreements provide for indemnification from the first dollar of losses without any threshold requirement. The reimbursable losses from the FDIC are based on the book value of the relevant loan as determined by the FDIC at the date of the transaction, January 30, 2009. New loans made after that date are not covered by the shared-loss agreements. The fair value of the shared-loss agreements is detailed below.
	The Company is accounting for the shared-loss agreements as an indemnification asset pursuant to the guidance in FASB ASC 805, Business Combinations. The FDIC indemnification asset is required to be measured in the same manner as the asset or liability to which it relates. The FDIC indemnification asset is measured separately from the covered loans and other real estate owned assets (OREO) because it is not contractually embedded in the covered loan and OREO and is not transferable should the Company choose to dispose of them. Fair value was estimated using projected cash flows available for loss sharing based on the credit adjustments estimated for each loan pool and other real estate owned and the loss sharing percentages outlined in the shared-loss agreements with the FDIC. These cash flows were discounted to reflect the uncertainty of the timing and receipt of the loss sharing reimbursement from the FDIC.
	Because the acquired loans are subject to shared-loss agreements and a corresponding indemnification asset exists to represent the value of expected payments from the FDIC, increases and decreases in loan accretable yield due to changing loss expectations will also have an impact to the valuation of the FDIC indemnification asset. Improvement in loss expectations will typically increase loan accretable yield and decrease the value of the FDIC indemnification asset and, in some instances, result in an amortizable premium on the FDIC indemnification asset. Increases in loss expectations will typically be recognized as impairment in the current period through allowance for loan losses, resulting in additional noninterest income for the amount of the increase in the FDIC indemnification asset.
	In addition to the premium amortization, the balance of the FDIC indemnification asset is affected by expected payments from the FDIC. Under the terms of the shared-loss agreements, the FDIC will reimburse the Company for loss events incurred related to the covered loan portfolio. These events include such things as future writedowns due to decreases in the fair market value of OREO, net loan charge-offs and recoveries, and net gains and losses on OREO sales.
	As discussed above, the shared-loss agreement for assets other than single family one-to-four residential mortgage assets expires March 2014. The portion of the FDIC indemnification asset related to those assets was $383,000 at September 30, 2013, of which $35,000 represented estimated losses to be reimbursed by the FDIC.

	The following table presents the balances of the FDIC indemnification asset at September 30, 2013 and December 31, 2012 (dollars in thousands):

Fair Values of Assets and Liabilities	Sep. 30, 2013
Fair Value Disclosures [Abstract]	'
Fair Values of Assets and Liabilities	'
	9. FAIR VALUES OF ASSETS AND LIABILITIES
	FASB ASC 820, Fair Value Measurements and Disclosures, defines fair value as the exchange price that would be received for an asset or paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. FASB ASC 820 requires that valuation techniques maximize the use of observable inputs and minimize the use of unobservable inputs and also establishes a fair value hierarchy that prioritizes the valuation inputs into three broad levels. The Company groups assets and liabilities at fair value in three levels, based on the markets in which the assets and liabilities are traded and the reliability of the assumptions used to determine fair value. These levels are:

		•		Level 1—Valuation is based upon quoted prices for identical instruments traded in active markets.

		•		Level 2—Valuation is based upon quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-based valuation techniques for which all significant assumptions are observable in the market or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

		•		Level 3—Valuation is determined using model-based techniques with significant assumptions not observable in the market. These unobservable assumptions reflect the Company’s own estimates of assumptions that market participants would use in pricing the asset or liability. Valuation techniques include the use of third party pricing services, option pricing models, discounted cash flow models and similar techniques.
	FASB ASC 825, Financial Instruments, allows an entity the irrevocable option to elect fair value for the initial and subsequent measurement for certain financial assets and liabilities on a contract-by-contract basis. The Company has not made any material FASB ASC 825 elections as of September 30, 2013.

	Assets and Liabilities Recorded at Fair Value on a Recurring Basis
	The Company utilizes fair value measurements to record adjustments to certain assets to determine fair value disclosures. Securities available for sale and loans held for sale are recorded at fair value on a recurring basis. The tables below present the recorded amount of assets and liabilities measured at fair value on a recurring basis (dollars in thousands):

	Total liabilities at fair value		$	—		$	—		$	—		$	—

	Investment securities available for sale
	Investment securities available for sale are recorded at fair value each reporting period. Fair value measurement is based upon quoted prices, if available. If quoted prices are not available, fair values are measured using independent pricing models or other model-based valuation techniques such as the present value of future cash flows, adjusted for the security’s credit rating, prepayment assumptions and other factors such as credit loss assumptions.
	The Company utilizes a third party vendor to provide fair value data for purposes of determining the fair value of its available for sale securities portfolio. The third party vendor uses a reputable pricing company for security market data. The third party vendor has controls and edits in place for month-to-month market checks and zero pricing, and a Statement on Standards for Attestation Engagements No. 16 report is obtained from the third party vendor on an annual basis. The Company makes no adjustments to the pricing service data received for its securities available for sale.
	Level 1 securities include those traded on an active exchange, such as the New York Stock Exchange, U.S. Treasury securities that are traded by dealers or brokers in active over-the-counter markets and money market funds. Level 2 securities include mortgage-backed securities issued by government sponsored entities, municipal bonds and corporate debt securities. Securities classified as Level 3 include asset-backed securities in less liquid markets.

	Loans held for sale
	The carrying amounts of loans held for sale approximate fair value.
	Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis
	The Company is also required to measure and recognize certain other financial assets at fair value on a nonrecurring basis on the consolidated balance sheet. The following table presents assets measured at fair value on a nonrecurring basis for the period ended September 30, 2013 and December 31, 2012 (dollars in thousands):

Impaired loans, non-covered
Loans for which it is probable that payment of interest and principal will not be made in accordance with the contractual terms of the loan agreement are considered impaired. Once a loan is identified as individually impaired, management measures the impairment in accordance with FASB ASC 310, Receivables. The fair value of impaired loans is estimated using one of several methods, including collateral value and discounted cash flows. Those impaired loans not requiring an allowance represent loans for which the fair value of the expected repayments or collateral exceeds the recorded investments in such loans. At September 30, 2013 and December 31, 2012, a majority of total impaired loans were evaluated based on the fair value of the collateral. The Company frequently obtains appraisals prepared by external professional appraisers for classified loans greater than $250,000 when the most recent appraisal is greater than 12 months old. When the fair value of the collateral is based on an observable market price or a current appraised value, the Company records the impaired loan within Level 2.
The Company may also identify collateral deterioration based on current market sales data, including price and absorption, as well as input from real estate sales professionals and developers, county or city tax assessments, market data and on-site inspections by Company personnel. Internally prepared estimates generally result from current market data and actual sales data related to the Company’s collateral or where the collateral is located. When management determines that the fair value of the collateral is further impaired below the appraised value and there is no observable market price, the Company records the impaired loan as nonrecurring Level 3. In instances where an appraisal received subsequent to an internally prepared estimate reflects a higher collateral value, management does not revise the carrying amount. Impaired loans can also be evaluated for impairment using the present value of expected future cash flows discounted at the loan’s effective interest rate. The measurement of impaired loans using future cash flows discounted at the loan’s effective interest rate rather than the market rate of interest rate is not a fair value measurement and is therefore excluded from fair value disclosure requirements. Reviews of classified loans are performed by management on a quarterly basis.

Bank premises and equipment held for sale
The fair value of bank premises and equipment held for sale relates to the pending branch sale (see Note 13) and reflects the value agreed upon in the branch sale agreement.
Other real estate owned, covered and non-covered
Other real estate owned (OREO) assets are adjusted to fair value less estimated selling costs upon transfer of the related loans to OREO property. Subsequent to the transfer, valuations are periodically performed by management and the assets are carried at the lower of carrying value or fair value less estimated selling costs. Fair value is based upon independent market prices, appraised values of the collateral or management’s estimation of the value of the collateral. When the fair value of the collateral is based on an observable market price or a current appraised value, the Company records the foreclosed asset within Level 2. When an appraised value is not available or management determines that the fair value of the collateral is further impaired below the appraised value due to such things as absorption rates and market conditions, the Company records the foreclosed asset within Level 3 of the fair value hierarchy.
Fair Value of Financial Instruments
FASB ASC 825, Financial Instruments, requires disclosure of the fair value of financial assets and financial liabilities, including those financial assets and financial liabilities that are not measured and reported at fair value on a recurring or nonrecurring basis. FASB ASC 825 excludes certain financial instruments and all nonfinancial instruments from its disclosure requirements. Accordingly, the aggregate fair value amounts presented may not necessarily represent the underlying fair value of the Company.
The following reflects the fair value of financial instruments, whether or not recognized on the consolidated balance sheet, at fair value measures by level of valuation assumptions used for those assets. This table excludes financial instruments for which the carrying value approximates fair value (dollars in thousands):

Borrowings			53,952			54,569			—			54,569			—

The following methods were used to estimate the fair value of all other financial instruments recognized in the accompanying balance sheets at amounts other than fair value as of September 30, 2013. The Company applied the provisions of FASB ASC 820 to the fair value measurements of financial instruments not recognized on the consolidated balance sheet at fair value. The provisions requiring the Company to maximize the use of observable inputs and to measure fair value using a notion of exit price were factored into the Company’s selection of inputs into its established valuation techniques.
Financial Assets
Cash and cash equivalents
The carrying amounts of cash and due from banks, interest bearing bank deposits, and federal funds sold approximate fair value.
Securities held for investment
For securities held for investment, fair values are based on quoted market prices or dealer quotes.
Restricted securities
The carrying value of restricted securities approximates their fair value based on the redemption provisions of the respective issuer.
Loans held for resale
The carrying amounts of loans held for resale approximate fair value except for loans sold related to the Georgia operations (see Note 13). Only those loans are reported in the table above. The fair value disclosed reflects the value agreed upon in the sale agreement.
Loans not covered by FDIC shared-loss agreement (non-covered loans)
The fair value of loans is estimated by discounting the future cash flows using the current rates at which similar loans would be made to borrowers with similar credit ratings and for the same remaining maturities. The fair value of impaired loans is consistent with the methodology used for the FASB ASC 820 disclosure for assets recorded at fair value on a nonrecurring basis presented above.
Loans covered by FDIC shared-loss agreement (covered loans)
Fair values for covered loans are based on a discounted cash flow methodology that considers various factors including the type of loan and related collateral, classification status, term of loan and whether or not the loans are amortizing. Loans were pooled together according to similar characteristics and were treated in the aggregate when applying various valuation techniques. The discount rates used for loans are based on the rates used at acquisition (which were based on market rates for new originations of comparable loans) adjusted for any material changes in interest rates since acquisition. Increases in cash flow expectations since acquisition resulted in estimated fair value being higher than carrying value. The increase in cash flows is also reflected in a transfer from unaccretable yield to accretable yield as disclosed in Note 4.

FDIC indemnification asset
Loss sharing assets are measured separately from the related covered assets as they are not contractually embedded in the covered assets and are not transferable with the assets should the Company choose to dispose of them. Fair value is estimated using projected cash flows related to the obligations under the shared-loss agreements based on the expected reimbursements for losses and the applicable loss sharing percentages. These expected reimbursements do not include reimbursable amounts related to future covered expenditures. These cash flows were discounted to reflect the uncertainty of the timing and receipt of the loss sharing reimbursement from the FDIC. A reduction in loss expectations has resulted in the estimated fair value of the FDIC indemnification asset being lower than its carrying value. This creates a premium that is amortized over the life of the asset and is reflected in Note 5.
Accrued interest receivable
The carrying amounts of accrued interest receivable approximate fair value.
Financial Liabilities
Noninterest bearing deposits
The carrying amount of noninterest bearing deposits approximates fair value.
Interest bearing deposits
The fair value of NOW accounts, savings accounts, and certain money market deposits is the amount payable on demand at the reporting date. The fair value of fixed-maturity certificates of deposit is estimated using the rates currently offered for deposits of similar remaining maturities.
Deposits held for sale
The fair value of deposits held for sale relates to the pending branch sale (see Note 13) and reflects the value agreed upon in the branch sale agreement.
Federal funds purchased
The carrying amount of federal funds purchased approximates fair value.
Borrowings
The fair values of the Company’s borrowings, such as FHLB advances, are estimated using discounted cash flow analyses based on the Company’s current incremental borrowing rates for similar types of borrowing arrangements.
Accrued interest payable
The carrying amounts of accrued interest payable approximate fair value.

Off-balance sheet financial instruments
The fair value of commitments to extend credit is estimated using the fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreements and the present creditworthiness of the counterparties. For fixed-rate loan commitments, fair value also considers the difference between current levels of interest rates and the committed rates. The fair value of stand-by letters of credit is based on fees currently charged for similar agreements or on the estimated cost to terminate them or otherwise settle the obligations with the counterparties at the reporting date. The Company’s off-balance sheet commitments are funded at current market rates at the date they are drawn upon. It is management’s opinion that the fair value of these commitments would approximate their carrying value, if drawn upon.
The Company assumes interest rate risk (the risk that general interest rate levels will change) as a result of its normal operations. As a result, the fair values of the Company’s financial instruments will change when interest rate levels change, and that change may be either favorable or unfavorable. Management attempts to match maturities of assets and liabilities to the extent believed necessary to minimize interest rate risk. However, borrowers with fixed rate obligations are less likely to prepay in a rising rate environment and more likely to prepay in a falling rate environment. Conversely, depositors who are receiving fixed rates are more likely to withdraw funds before maturity in a rising rate environment and less likely to do so in a falling rate environment. Management monitors rates and maturities of assets and liabilities and attempts to minimize interest rate risk by adjusting terms of new loans and deposits and by investing in securities with terms that mitigate the Company’s overall interest rate risk.

	Basic earnings per common share (EPS) is computed by dividing net income or loss available to common stockholders by the weighted average number of common shares outstanding during the period. Diluted EPS is computed using the weighted average number of common shares outstanding during the period, including the effect of all potentially dilutive common shares outstanding attributable to stock instruments (dollars and shares in thousands, except per share data):

	Excluded from the computation of diluted earnings per common share were 846,000 and 66,000 common shares issuable under awards, options or warrants during the three and nine months ended September 30, 2013, because their inclusion would be anti-dilutive. Anti-dilutive common shares issuable under awards, options or warrants of 1.3 million were excluded for the three and nine months ended September 30, 2012.
	In December 2008, the Company issued 17,680 shares of its Fixed Rate Cumulative Perpetual Preferred Stock, Series A to the United States Department of Treasury in connection with the Company’s participation in the Treasury’s TARP Capital Purchase Program. Under the terms of the Series A Preferred Stock, the Company is required to pay cumulative dividends on a quarterly basis at a rate of 5% per year on such amount through the February 2014 payment. After the February 2014 payment, the dividend rate automatically increases to 9% per year. The Company may defer dividend payments, but the dividend is a cumulative dividend that accrues for payment in the future. Deferred dividends also accrue interest at the same rate as the dividend. The failure to pay dividends for six dividend periods triggers the right for the holder of the Series A Preferred Stock to appoint two directors to the Company’s board.
	On July 24, 2013, the Company repurchased 4,500 shares of the original 17,680 shares of Series A Preferred Stock. The Company funded the repurchase through the earnings of its banking subsidiary. The form of the repurchase was a redemption under the terms of the TARP preferred stock. The Company paid the Treasury $4.5 million, which represented 100% of the par value of the preferred stock repurchased plus accrued dividends with respect to such shares.
	As of September 30, 2013, the Company was current in its payment of dividends, payable quarterly in the amount of $165,000, with respect to the Series A Preferred Stock.

	13	BRANCH SALE
	On August 19, 2013, the Company entered into a definitive agreement to sell the four branches located in Georgia and related deposits to Community & Southern Bank, headquartered in Atlanta, Georgia (the “Branch Sale”). The Branch Sale was completed November 8, 2013. The Branch Sale resulted in the transfer of $193.2 million of deposits and $20,000 of consumer loans associated with such deposits to Community & Southern Bank in exchange for the payment of a deposit premium of $2.6 million. At September 30, 2013, $192.2 million of deposits and $47,000 of consumer loans were classified as held for sale. Certain fixed assets with a fair value at September 30, 2013 of $5.2 million (cost, net of accumulated depreciation of $1.2 million), which were also classified as held for sale, were also sold. In addition, $1.5 million of remaining unamortized intangible assets at September 30, 2013 related to customers and deposits associated with the pending Branch Sale.

	The following table summarizes estimated deposits at September 30, 2013 related to the Branch Sale (dollars in thousands):




	Deposits
	Noninterest bearing		$	16,140
	Interest bearing			176,059

	Total deposits		$	192,199

	On September 30, 2013, the Company entered into a definitive agreement to sell up to $25.1 million in loans held at the Georgia branches to Pinnacle Bank, headquartered in Elberton, Georgia (the “Loan Sale”) at a premium of 1.0%. These loans were classified as held for sale at September 30, 2013 and were carried at the lower of cost or fair value. The Loan Sale was completed October 25, 2013, at which time $24.3 million in loans were sold.

	The following summarizes estimated loans at September 30, 2013 related to the Loan Sale (dollars in thousands):




	Mortgage loans on real estate:
	Residential 1-4 family		$	2,642

	Total loans		$	25,081

	Based on the premiums outlined above, the Company recorded a net gain on the two transactions combined of $254,000 subsequent to September 30, 2013. This gain was net of the deposit premium of $2.6 million, a write off of $1.5 million of existing core deposit intangibles, a $827,000 loss on the sale of fixed assets, a $243,000 gain on the sale of loans and $259,000 in transaction related costs.

Organization	'
	Organization
	Community Bankers Trust Corporation (the “Company”) is a bank holding company that was incorporated under Delaware law on April 6, 2005. The Company is headquartered in Glen Allen, Virginia and is the holding company for Essex Bank (the “Bank”), a Virginia state bank with 19 full-service offices in Virginia and Maryland as of November 12, 2013. The Bank also operates two loan production offices.
	The Bank engages in a general commercial banking business and provides a wide range of financial services primarily to individuals and small businesses, including individual and commercial demand and time deposit accounts, commercial and industrial loans, consumer and small business loans, real estate and mortgage loans, investment services, on-line and mobile banking products, and safe deposit box facilities. Thirteen offices are located in Virginia, from the Chesapeake Bay to just west of Richmond and six are located in Maryland along the Baltimore-Washington corridor.
	Prior to November 8, 2013, the Bank also had four full-service offices in Georgia. The Bank sold those offices and related deposits to Community and Southern Bank on November 8, 2013. See Note 13 for additional information.
Financial Statements	'
	Financial Statements
	The consolidated statements presented include accounts of the Company and the Bank, its wholly-owned subsidiary. All material intercompany balances and transactions have been eliminated. The statements should be read in conjunction with the Company’s consolidated financial statements and the accompanying notes to consolidated financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2012. The accounting and reporting policies of the Company conform to generally accepted accounting principles (GAAP) and to the general practices within the banking industry. The interim financial statements have not been audited; however, in the opinion of management, all adjustments, consisting of normal accruals, were made that are necessary to present fairly the balance sheet of the Company as of September 30, 2013, changes in stockholders’ equity and cash flows for the nine months ended September 30, 2013, and the income statement and statement of comprehensive income for the three and nine months ended September 30, 2013. Results for the nine month period ended September 30, 2013 are not necessarily indicative of the results that may be expected for the year ended December 31, 2013.
	The financial information contained within the statements is, to a significant extent, financial information that is based on measures of the financial effects of transactions and events that have already occurred. A variety of factors could affect the ultimate value that is obtained when either earning income, recognizing an expense, recovering an asset or relieving a liability. The Company uses historical loss factors as one factor in determining the inherent loss that may be present in its loan portfolio. Actual losses could differ significantly from the historical factors that the Company uses. In addition, GAAP itself may change from one previously acceptable method to another method. Although the economics of the Company’s transactions would be the same, the timing of events that would impact its transactions could change.
	Certain reclassifications have been made to prior period balances to conform to the current period presentation.
	In preparing these financial statements, the Company has evaluated subsequent events and transactions for potential recognition or disclosure through the date the financial statements were issued.
Recent Accounting Pronouncements	'
	Recent Accounting Pronouncements
	In July 2013, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2013-11, Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists (a consensus of the FASB Emerging Issues Task Force). U.S. GAAP does not include explicit guidance on the financial statement presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. The amendments in this ASU state that an unrecognized tax benefit, or a portion of an unrecognized tax benefit, should be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward, except as follows. To the extent a net operating loss carryforward, a similar tax loss, or a tax credit carryforward is not available at the reporting date under the tax law of the applicable jurisdiction to settle any additional income taxes that would result from the disallowance of a tax position or the tax law of the applicable jurisdiction does not require the entity to use, and the entity does not intend to use, the deferred tax asset for such purpose, the unrecognized tax benefit should be presented in the financial statements as a liability and should not be combined with deferred tax assets.
	The amendments in this ASU are effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. Early adoption is permitted. Retrospective application is permitted. The Company currently presents these tax items in accordance with this guidance; therefore, no changes are necessary for adoption.
	In February 2013, the FASB issued ASU No. 2013-02, Comprehensive Income (Topic 220): Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income, to improve the transparency of reporting these reclassifications. Other comprehensive income includes gains and losses that are initially excluded from net income for an accounting period. Those gains and losses are later reclassified out of accumulated other comprehensive income into net income. The amendments in this ASU do not change the current requirements for reporting net income or other comprehensive income in financial statements. All of the information that this ASU requires is already required to be disclosed elsewhere in the financial statements under U.S. GAAP. The new amendments will require an organization to:

		•	Present (either on the face of the statement where net income is presented or in the notes) the effects on the line items of net income of significant amounts reclassified out of accumulated other comprehensive income - but only if the item reclassified is required under U.S. GAAP to be reclassified to net income in its entirety in the same reporting period.

		•	Cross-reference to other disclosures currently required under U.S. GAAP for other reclassification items, which are not required under U.S. GAAP to be reclassified directly to net income in their entirety in the same reporting period.
	The amendments apply to all public and private companies that report items of other comprehensive income. Public companies are required to comply with these amendments for all reporting periods (interim and annual). The amendments are effective for reporting periods beginning after December 15, 2012. Early adoption is permitted. The Company adopted this guidance with no material impact on its consolidated financial statements.
Financing Receivable Allowance for Credit Losses	'
	At September 30, 2013 and December 31, 2012, the Company’s allowance for credit losses was comprised of the following: (i) specific valuation allowances calculated in accordance with FASB ASC 310, Receivables, (ii) general valuation allowances calculated in accordance with FASB ASC 450, Contingencies, based on economic conditions and other qualitative risk factors, and (iii) historical valuation allowances calculated using historical loan loss experience. Management identified loans subject to impairment in accordance with ASC 310.
Loans Receivable Troubled Debt Restructuring	'
	In accordance with FASB ASU 2011-02, Receivables (Topic 310): A Creditor’s Determination of Whether a Restructuring is a Troubled Debt Restructuring, the Company assesses all loan modifications to determine whether they are considered troubled debt restructurings (TDRs) under the guidance.
Loans and Debt Securities Acquired	'
	The Company is applying the provisions of FASB ASC 310-30, Loans and Debt Securities Acquired with Deteriorated Credit Quality, to all loans acquired in the SFSB transaction (the “covered loans”).
Business Combinations	'
	The Company is accounting for the shared-loss agreements as an indemnification asset pursuant to the guidance in FASB ASC 805, Business Combinations.
Intangible Assets Finite Lived	' Core deposit intangibles are recognized, amortized and evaluated for impairment as required by FASB ASC 350, Intangibles.
Fair Value Measurement	'
	FASB ASC 820, Fair Value Measurements and Disclosures, defines fair value as the exchange price that would be received for an asset or paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date.
Fair Value of Financial Instruments	'
	FASB ASC 825, Financial Instruments, allows an entity the irrevocable option to elect fair value for the initial and subsequent measurement for certain financial assets and liabilities on a contract-by-contract basis.
Impaired Financing Receivable	'
	Once a loan is identified as individually impaired, management measures the impairment in accordance with FASB ASC 310, Receivables.
