Nature of Banking Activities and Significant Accounting Policies [Abstract]
Nature of Banking Activities and Significant Accounting Policies	Note 1. Nature of Banking Activities and Significant Accounting Policies  Organization Community Bankers Trust Corporation (the “Company”) is headquartered in Richmond, Virginia and is the holding company for Essex Bank (the “Bank”), a Virginia state bank with 25 full-service offices in Virginia and Maryland. The Bank engages in a general commercial banking business and provides a wide range of financial services primarily to individuals, small businesses and larger commercial companies, 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 cash management services. 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, 2017. The accounting and reporting policies of the Company conform to U.S. 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, 2018, the statements of income and comprehens ive income for the three and nine months ended September 30, 2018, and the statements of changes in shareholders’ e quity and cash flows for the nine months ended September 30, 2018. Results for the nine month period ended September 30, 2018 are not necessarily indicative of the results that may be expected for the year ending December 31, 2018. 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. 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. Certain reclassifications have been made to prior period balances to conform to the current year presentations. Such reclassifications had no impact on net income or shareholders ’ equity. Recent Accounting Pron oun cements  In August 2018 the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement. The ASU removes, modifies, and adds to existing fair value measurement disclosure requirements.  The following public company disclosure requirements are removed: · Transfers between Level 1 and Level 2 of the fair value hierarchy · The policy for determining when transfers between any of the three levels have occurred · The valuation processes used for Level 3 measurements  The following public company disclosure requirements are modified: · For certain investments that calculate the net asset value, timing of liquidation and redemption restrictions lapsing if the latter has been communicated to the reporting entity · A clarification that the Level 3 measurement uncertainty disclosure should communicate information about the uncertainty at the balance sheet date  The following public company disclosure requirements are new: · The changes in unrealized gains and losses for the period included in other comprehensive income for recurring Level 3 instruments held at the balance sheet date · The range and weighted average of significant unobservable inputs used for Level 3 measurements. For certain unobservable inputs, an option to disclose other quantitative information in place of the weighted average is available to the extent that it would be a more reasonable and rational method to reflect the distribution of unobservable inputs.  The ASU is effective for all entities in fiscal years beginning after December 15, 2019 and interim periods within those fiscal years. Early adoption is permitted. In addition, an entity may early adopt any of the removed or modified disclosures immediately and delay adoption of the new disclosures until the effective date. The Company does not expect the adoption of ASU 2018-13 to have a material impact on its consolidated financial statements.  Also in August 2018, the FASB issued ASU 2018-14, Compensation—Retirement Benefits—Defined Benefit Plans—General (Topic 715-20): Disclosure Framework—Changes to the Disclosure Requirements for Defined Benefit Plan . This ASU modifies the disclosure requirements for employers that sponsor defined benefit pension or other postretirement plans by eliminating the requirement to disclose the amounts in accumulated other comprehensive income expected to be recognized as components of net periodic benefit cost over the next fiscal year and adding a requirement to disclose an explanation of the reasons for significant gains and losses related to changes in the benefit obligation for the period. The ASU is effective for fiscal years ending after December 15, 2020. Early adoption is permitted. The Company does not expect the adoption of ASU 2018-14 to have a material impact on its consolidated financial statements.                    · In June 2018, the FASB issued ASU 2018-07, Compensation- Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting . The amendments expand the scope of Topic 718 to include share-based payments issued to nonemployees for goods or services, which were previously excluded. The amendments will align the accounting for share-based payments to nonemployees and employees more similarly. The amendments are effective for fiscal years beginning after December 15, 2018 and interim periods within those fiscal years. Early adoption is permitted. The Company does not expect the adoption of ASU 2018-07 to have a material impact on its consolidated financial statements.

Gains and losses on the sale of securities are determined using the specific identification method.

The unrealized losses are from 2 43 securities at September 30, 2018. Of those , 234 are investment grade, have U.S. government agency guarantees, or are backed by the full faith and credit of local municipalities throughout the United States. F ive investment grade asset-backed securities comprised of student loan pools included in corporate obligations and four corporate bonds make up the remaining securities with unrealized losses at September 30, 2018. The Company considers the reason for impairment, length of impairment, and ability and intent 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 or reach maturity. 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 $ 59 . 4 million and $71.7 million at September 30, 2018 and December 31, 2017, respectively, were pledged to secure public deposits as required or permitted by law. Securities with amortized costs of $7.0 million at each of September 30, 2018 and December 31, 2017 were pledged to secure lines of credit at the Federal Reserve discount window. At each of September 30, 2018 and December 31, 2017, 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.

Loans and Related Allowance for Loan Losses	 Note 3. Loans and Related Allowance for Loan Losses  The Company’s loans, net o f deferred fees and costs, at September 30, 2018 and December 31, 2017 were comprised of the following (dollars in thousands):    September 30, 2018 December 31, 2017  Amount % of Loans Amount % of Loans  Mortgage loans on real estate:  Residential 1-4 family $ 216,203 22.46 % $ 227,542 24.16 %  Commercial 358,490 37.25 366,331 38.89  Construction and land development 135,021 14.03 107,814 11.44  Second mortgages 7,179 0.75 8,410 0.89  Multifamily 52,255 5.43 59,024 6.27  Agriculture 8,066 0.84 7,483 0.79  Total real estate loans 777,214 80.76 776,604 82.44  Commercial loans 170,310 17.70 159,024 16.88  Consumer installment loans 13,135 1.36 5,169 0.55  All other loans 1,766 0.18 1,221 0.13  Total loans $ 962,425 100.00 % $ 942,018 100.00 %  The Company held $18.0 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, 2018 and December 31, 2017 . As these loans are 100% guaranteed by the USDA, no loan loss allowance is required. These loan balances included a purchase premium of $ 1.3 million and $ 824,000 at September 30, 2018 and December 31, 2017, respectively. The purchase premium is amortized as an adjustment of the related loan yield on a straight line basis, which is substantially equivalent to the results obtained using the effective interest method. At September 30, 2018 and December 31, 2017, the Company’s allowance for loan losses was comprised of the following: (i) a specific valuation component calculated in accordance with FASB Accounting Standards Codification (ASC) 310, Receivables, (ii) a general valuation component calculated in accordance with FASB ASC 450, Contingencies , based on historical loan loss experience, current economic conditions and other qualitative risk factors, and (iii) an unallocated component to cover uncertainties that could affect management’s estimate of probable losses. Management identified loans subject to impairment in accordance with ASC 310.  The following table summarizes information related to impaired loans as of September 30, 2018 (dollars in thousands):     Three months ended Nine months ended  September 30, 2018 September 30, 2018 September 30, 2018  With no related allowance recorded: Recorded Investment (1) Unpaid Principal Balance (2) Related Allowance Average Investment Interest Recognized Average Investment Interest Recognized  Mortgage loans on real estate:  Residential 1-4 family $ 1,579 $ 1,898 $ — $ 1,716 $ 11 $ 1,802 $ 33  Commercial 3,544 4,202 — 3,561 38 3,702 112  Construction and land development 464 464 — 426 — 318 —  Multifamily 2,559 2,559 — 2,559 31 1,279 92  Total real estate loans 8,146 9,123 — 8,262 80 7,101 237  Commercial loans — — — 136 — 589 —  Subtotal impaired loans with no valuation allowance 8,146 9,123 — 8,398 80 7,690 237  With an allowance recorded:  Mortgage loans on real estate:  Residential 1-4 family 2,404 2,901 317 2,298 20 2,266 57  Commercial 1,653 2,127 472 1,600 4 1,063 13  Construction and land development 4,146 5,414 507 4,471 — 4,589 —  Agriculture — — — — — 34 —  Total real estate loans 8,203 10,442 1,296 8,369 24 7,952 70  Commercial loans 711 717 179 478 1 383 3  Consumer installment loans 5 5 1 3 — 4 —  Subtotal impaired loans with a valuation allowance 8,919 11,164 1,476 8,850 25 8,339 73  Total:  Mortgage loans on real estate:  Residential 1-4 family 3,983 4,799 317 4,014 31 4,068 90  Commercial 5,197 6,329 472 5,161 42 4,765 125  Construction and land development 4,610 5,878 507 4,897 — 4,907 —  Multifamily 2,559 2,559 — 2,559 31 1,279 92  Agriculture — — — — — 34 —  Total real estate loans 16,349 19,565 1,296 16,631 104 15,053 307  Commercial loans 711 717 179 614 1 972 3  Consumer installment loans 5 5 1 3 — 4 —  Total impaired loans $ 17,065 $ 20,287 $ 1,476 $ 17,248 $ 105 $ 16,029 $ 310  (1) The amount of the investment in a loan, which is not net of a valuation allowance, but which does reflect any direct write-down of the investment .

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 $18.0 million and $18.0 million at September 30, 2018 and December 31, 2017, 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. The possibility of loss is extremely high.  The following tables present the composition of loans by credit quality indicator at September 30, 2018 and December 31, 2017 (dollars in thousands):     September 30, 2018  Pass Special Mention Substandard Doubtful Total  Mortgage loans on real estate:  Residential 1-4 family $ 211,550 $ 3,016 $ 1,637 $ — $ 216,203  Commercial 350,683 4,072 3,735 — 358,490  Construction and land development 130,213 198 4,610 — 135,021  Second mortgages 7,084 95 — — 7,179  Multifamily 49,089 607 2,559 — 52,255  Agriculture 8,066 — — — 8,066  Total real estate loans 756,685 7,988 12,541 — 777,214  Commercial loans 167,431 2,342 537 — 170,310  Consumer installment loans 13,122 8 5 — 13,135  All other loans 1,766 — — — 1,766  Total loans $ 939,004 $ 10,338 $ 13,083 $ — $ 962,425     December 31, 2017  Pass Special Mention Substandard Doubtful Total  Mortgage loans on real estate:  Residential 1-4 family $ 222,026 $ 3,442 $ 2,074 $ — $ 227,542  Commercial 355,188 8,145 2,998 — 366,331  Construction and land development 103,356 182 4,276 — 107,814  Second mortgages 8,187 223 — — 8,410  Multifamily 56,452 — 2,572 — 59,024  Agriculture 7,010 385 88 — 7,483  Total real estate loans 752,219 12,377 12,008 — 776,604  Commercial loans 156,604 1,171 1,249 — 159,024  Consumer installment loans 5,137 25 7 — 5,169  All other loans 1,221 — — — 1,221  Total loans $ 915,181 $ 13,573 $ 13,264 $ — $ 942,018  In accordance with FASB Accounting Standards Update (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. The Company had 24 and 23 loans that met the definition of a TDR at September 30, 2018 and 2017, respectively.   During the three months ended September 30, 2018, the Company modified one commercial real estate loan that was considered to be a TDR. The Company restructured the terms for this loan, which had a pre- and post -modification balance of $126,000 . During the nine months ended September 30, 2018, the Company modified one multifamily loan and one commercial real estate loan that w ere considered to be TDR s, which had a total pre- and post-modification balance of $2.6 million and $126,000 , respectively. The Company restructured the terms for both loans.  During the three months ended September 30, 2017, the Company modified two 1-4 family loans that were considered to be TDRs. The Company lowered the interest rate and extended the term for each of the 1-4 family loans, which had a pre- and post -modification balance of $354,000 . During the nine months ended September 30, 2017, the Company modified three 1-4 family loans and one agriculture loan that were considered to be TDRs. The Company extended the terms for two of the 1-4 family loans and lowered the interest rate for each of these loans, which had a pre- and post -modification balance of $1.1 million. The Company extended the term for the agriculture loan, which had a pre- and post -modification balance of $258,000 . A loan is considered to be in default if it is 90 days or more past due. There were no TDRs that had been restructured during the previous 12 months that resulted in default during either of the three and nine months ended September 30, 2018 and 2017. 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 .  At September 30, 2018, the Company had 1-4 family mortgages in the amount of $112.3 million pledged to the Federal Home Loan Bank with a lendable collateral value of $89.8 million .

PCI Loans and Related Allowance for Loan Losses [Abstract]
PCI Loans and Related Allowance for Loan Losses	Note 4. PCI 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 “PCI 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, 2018 and December 31, 2017, the outstanding contractual balance of the PCI loans was $63.4 million and $71.0 million, respectively. The carrying amount, by loan type, as of these dates is as follows (dollars in thousands):      September 30, 2018 December 31, 2017  Amount % of PCI Loans Amount % of PCI Loans  Mortgage loans on real estate:  Residential 1-4 family $ 35,053 89.55 % $ 39,805 89.79 %  Commercial 759 1.94 547 1.23  Construction and land development 1,350 3.45 1,588 3.58  Second mortgages 1,735 4.43 2,136 4.82  Multifamily 247 0.63 257 0.58  Total real estate loans 39,144 100.00 44,333 100.00  Total PCI loans $ 39,144 100.00 % $ 44,333 100.00 %  During the three and nine months ended September 30, 2018, the Company recorded charge-offs of $63,000 on PCI loans in the residential 1-4 family loan category. There was no activity in the allowance for loan losses on PCI loans for the three and nine months ended September 30, 2017.   The following table presents information on the PCI loans collectively evaluated for impairment in the allowance for loan losses at September 30, 2018 and December 31, 2017 (dollars in thousands):     September 30, 2018 December 31, 2017  Allowance for loan losses Recorded investment in loans Allowance for loan losses Recorded investment in loans  Mortgage loans on real estate:  Residential 1-4 family $ 137 $ 35,053 $ 200 $ 39,805  Commercial — 759 — 547  Construction and land development — 1,350 — 1,588  Second mortgages — 1,735 — 2,136  Multifamily — 247 — 257  Total real estate loans 137 39,144 200 44,333  Total PCI loans $ 137 $ 39,144 $ 200 $ 44,333  The change in the accr etable yield balance for the nine months ended September 30, 2018 and the year ended December 31, 2017, is as follows (dollars in thousands):       Balance, January 1, 2017 $ 48,355  Accretion (5,729)  Reclassification from nonaccretable difference 1,500  Balance, December 31, 2017 $ 44,126  Accretion (3,935)  Reclassification to nonaccretable difference (1,400)  Balance, September 30, 2018 $ 38,791  The PCI loans were not classified as nonperforming assets as of September 30, 2018, as the loans are accounted for on a pooled basis, and interest income, through accretion of the difference between the carrying amount of the loans and the expected cash flows, is being recognized on all PCI loans.

Fair Values of Assets and Liabilities [Abstract]
Fair Values of Assets and Liabilities	  Note 8. 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, 2018.    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 the cash flow hedge 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):      September 30, 2018  Total Level 1 Level 2 Level 3  Investment securities available for sale  U.S. Treasury issue and other U.S. Gov’t agencies $ 26,037 $ 1,984 $ 24,053 $ -  U.S. Gov’t sponsored agencies 8,424 - 8,424 -  State, county and municipal 115,744 1,447 114,297 -  Corporate and other bonds 9,651 - 9,651 -  Mortgage backed – U.S. Gov’t agencies 14,254 - 14,254 -  Mortgage backed – U.S. Gov’t sponsored agencies 26,493 1,387 25,106 -  Total investment securities available for sale 200,603 4,818 195,785 -  Cash flow hedge 353 - 353 -  Total assets at fair value $ 200,956 $ 4,818 $ 196,138 $ -  Total liabilities at fair value $ - $ - $ - $ -      December 31, 2017  Total Level 1 Level 2 Level 3  Investment securities available for sale  U.S. Treasury issue and other U.S. Gov’t agencies $ 27,183 $ - $ 27,183 $ -  U.S. Gov’t sponsored agencies 9,278 - 9,278 -  State, county and municipal 125,760 332 125,428 -  Corporate and other bonds 7,460 - 7,460 -  Mortgage backed – U.S. Gov’t agencies 18,515 - 18,515 -  Mortgage backed – U.S. Gov’t sponsored agencies 16,638 - 16,638 -  Total investment securities available for sale 204,834 332 204,502 -  Cash flow hedge 177 - 177 -  Total assets at fair value $ 205,011 $ 332 $ 204,679 $ -  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 (Level 1). Quoted prices are available within the same month as the settlement date of the related security transaction. As a result, investment securities held at December 31, 2017 priced as Level 1 that were still held at September 30, 2018 were priced as Level 2 securities. 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 (Level 2).  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 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. Cash flow hedge The fair values of interest rate swaps are determined using the market standard methodology of netting the discounted future fixed cash receipts (or payments) and the discounted expected variable cash payments (or receipts). The variable cash payments (or receipts) are based on an expectation of future interest rates (forward curves) derived from observable market interest rate curves. 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 tables present assets measured at fair value on a nonrecurring basis as of September 30, 2018 and December 31, 2017 (dollars in thousands):     September 30, 2018  Total Level 1 Level 2 Level 3  Impaired loans $ 8,825 $ — $ — $ 8,825  Bank premises and equipment held for sale 1,252 — 700 552  Other real estate owned 1,732 — — 1,732  Total assets at fair value $ 11,809 $ — $ 700 $ 11,109  Total liabilities at fair value $ — $ — $ — $ —     December 31, 2017  Total Level 1 Level 2 Level 3  Impaired loans $ 7,915 $ — $ 1,306 $ 6,609  Other real estate owned 2,791 — 1,203 1,588  Total assets at fair value $ 10,706 $ — $ 2,509 $ 8,197  Total liabilities at fair value $ — $ — $ — $ —  Impaired loans  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, 2018 and December 31, 2017, 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 18 months old and/or deemed to be invalid. The Company may also utilize internally prepared estimates that generally result from current market data and actual sales data related to the Company’s collateral. When the fair value of the collateral is based on an observable market price or a current appraised value without further adjustment for unobservable inputs , 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. When 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, and there is no observable market price, the Company records the impaired loan as nonrecurring Level 3. At September 30, 2018 and December 31, 2017, the Level 3 weighted average adjustments related to impaired loans were 19.0% and 38.0% , respectively. 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 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 was determined using the adjusted appraisal methodology described in the other real estate owned (OREO) asset section below.  Other real estate owned  OREO assets are adjusted to fair value less estimated disposal costs upon transfer of the related loans to OREO, establishing a new cost basis. 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 disposal 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. These tables exclude financial instruments for which the carrying value approximates fair value (dollars in thousands):    September 30, 2018  Carrying Value Estimated Fair Value Level 1 Level 2 Level 3 Financial assets:  Securities held to maturity $43,559 $43,195 $ — $43,195 $ —  Loans, net of allowance 953,432 958,935 — — 958,935  PCI loans, net of allowance 39,007 42,519 — — 42,519  Financial liabilities:  Interest bearing deposits 975,034 973,178 — 973,178 —  Borrowings 67,944 67,591 — 67,591 —    December 31, 2017  Carrying Value Estimated Fair Value Level 1 Level 2 Level 3 Financial assets:  Securities held to maturity $46,146 $46,888 $ — $46,888 $ —  Loans, net of allowance 933,049 933,938 — 927,329 6,609  PCI loans, net of allowance 44,133 48,655 — — 48,655  Financial liabilities:  Interest bearing deposits 942,736 943,037 — 943,037 —  Borrowings 105,553 105,363 — 105,363 —

Earnings Per Common Share [Abstract]
Earnings Per Common Share	 Note 9. Earnings Per Common Share  Basic earnings per common share (EPS) is computed by dividing net income 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. The following table presents basic and diluted EPS for the three and nine months ended September 30, 2018 and 2017 (dollars and shares in thousands, except per share data):    Net Income (Numerator) Weighted Average Common Shares (Denominator) Per Common Share Amount  For the three months September 30, 2018  Basic EPS $ 3,955 22,115 $ 0.18  Effect of dilutive stock awards — 512 (0.01)  Diluted EPS $ 3,955 22,627 $ 0.17   For the three months ended September 30, 2017  Basic EPS $ 2,416 22,041 $ 0.11  Effect of dilutive stock awards — 501 —  Diluted EPS $ 2,416 22,542 $ 0.11   For the nine months ended September 30, 2018  Basic EPS $ 10,331 22,095 $ 0.47  Effect of dilutive stock awards — 481 (0.01)  Diluted EPS $ 10,331 22,576 $ 0.46   For the nine months ended September 30, 2017  Basic EPS $ 7,843 22,000 $ 0.36  Effect of dilutive stock awards — 491 (0.01)  Diluted EPS $ 7,843 22,491 $ 0.35 T here were no antidilutive exclusions from the computation of diluted earnings per common share for the three and nine months ended September 30, 2018 and 2017, respectively.

Cash Flow Hedge [Abstract]
Cash Flow Hedge	Note 11. Cash Flow Hedge  On November 7, 2014, the Company entered into an interest rate swap with a total notional amount of $30 million. The Company designated the swap as a cash flow hedge intended to protect against the variability in the expected future cash flows on the designated variable rate borrowings. The swap hedges the interest rate risk, wherein the Company will receive an interest rate based on the three month LIBOR from the counterparty and pays an interest rate of 1.69% to the same counterparty calculated on the notional amount for a term of five years. The Company intends to sequentially issue a series of three month fixed rate debt as part of a planned roll-over of short term debt for five years. The forecasted funding will be provided through one of the following wholesale funding sources: a new FHLB advance, a new repurchase agreement, or a pool of brokered CDs, based on whichever market offers the most advantageous pricing at the time that pricing is first initially determined for the effective date of the swap and each reset period thereafter. Each quarter when the Company rolls over the three month debt, it will decide at that time which funding source to use for that quarterly period. The swap was entered into with a counterparty that met the Company’s credit standards, and the agreement contains collateral provisions protecting the at-risk party. The Company believes that the credit risk inherent in the contract is not significant. The Company had $0 and $390,000 of cash pledged as collateral for the periods ended September 30, 2018 and December 31, 2017, respectively. Amounts receivable or payable are recognized as accrued under the terms of the agreements. In accordance with FASB ASC 815, Derivatives and Hedging , the Company has designated the swap as a cash flow hedge, with the effective portions of the derivatives’ unrealized gains or losses recorded as a component of other comprehensive income. The ineffective portions of the unrealized gains or losses, if any, would be recorded in other operating expense. The Company has assessed the effectiveness of each hedging relationship by comparing the changes in cash flows on the designated hedged item. The Company’s cash flow hedge was deemed to be effective for the three and nine months ended September 30, 2018 and 2017. The fair value of the Company’s cash flow hedge was an unrealized gain of $353,000 and $177,000 at September 30, 2018 and December 31, 2017, respectively, and was recorded in other assets. The gain was recorded as a component of other comprehensive (loss) income net of associated tax effects.

Revenue from Contract with Customer [Abstract]
Revenue Recognition	Note 12. Revenue Recognition  On January 1, 2018, the Company adopted FASB ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606), and all subsequent ASUs that modified Topic 606. The implementation of the new standard did not have a material impact on the measurement or recognition of revenue; as such, a cumulative effect adjustment to opening retained earnings was not deemed necessary. Topic 606 does not apply to revenue associated with financial instruments, including revenue from loans and securities. In addition, certain noninterest income streams such as fees associated with mortgage servicing rights, financial guarantees, derivatives, and certain credit card fees are also not in scope of the new guidance. Topic 606 is applicable to noninterest revenue streams such as deposit related fees, interchange fees, merchant income, and brokerage fees and commissions. However, the recognition of these revenue streams did not change significantly upon adoption of Topic 606. Substantially all of the Company ’ s revenue is generated from contracts with customers. Noninterest revenue streams in-scope of Topic 606 are discussed below.  Service charges on deposit accounts The Company earns fees from its deposit customers for transaction-based, account maintenance, and overdraft services. Transaction-based fees, which include services such as stop payment charges, statement rendering, and ACH fees, are recognized at the time the transaction is executed as that is the point in time the Company fulfills the customer’s request. Account maintenance fees, which relate primarily to monthly maintenance, are earned over the course of a month, representing the period over which the Company satisfies the performance obligation. Overdraft fees are recognized at the point in time that the overdraft occurs. Service charges on deposits are withdrawn from the customer’s account balance.  Interchange and ATM fees  The Company earns interchange and ATM fees from debit/credit cardholder transactions conducted through the Visa and ATM payment networks. Interchange fees from cardholder transactions represent a percentage of the underlying transaction value and are recognized daily, concurrently with the transaction processing services provided to the cardholder. Because the Company acts as an agent and does not control the services rendered to the customers, related costs are netted against the fee income. These costs were included in other operating expenses prior to the adoption of Topic 606.  Brokerage fees and commissions  Brokerage fees and commissions consist of other recurring revenue streams such as commissions from sales of mutual funds and other investments to customers by a third-party service provider and investment advisor fees. The Company receives commissions from the third-party service provider on a monthly basis based upon customer activity for the month. The investment advisor fees are charged to the customer ’ s account in advance on the first month of the quarter, and the revenue is recognized over the following three-month period. The following table presents noninterest income, segregated by revenue streams in-scope and out-of-scope of Topic 606, for the three and nine months ended September 30, 2018 and 2017 (dollars in thousands):      Three months ended Nine months ended  September 30, 2018 September 30, 2017 September 30, 2018 September 30, 2017  Noninterest income  In-scope of Topic 606:  Service charges o n deposit accounts $ 411 $ 376 $ 1,192 $ 1,130  Interchange and ATM fees 215 183 626 535  Brokerage fee s and commissions 76 68 272 208  Noninterest income (in-scope of Topic 606) 702 627 2,090 1,873  Noninterest income (out-of-scope of Topic 606) 509 371 1,289 1,155  Total noninterest income $ 1,211 $ 998 $ 3,379 $ 3,028

Bank Premises and Equopment Held for Sale	Note 13. B ank Premises and Equipment Held for Sale  The Company closed its Prince Street branch located in Tappahan n ock, Virginia as of the close of business June 29, 2018. From a historical perspective, when the Company opened its Dillard branch, also in Tappahannock, the Company’s intention was to consolidate the Prince Street branch into the newer Dillard branch, which was built as a larger and modern banking facility. The Company is now following through with its intention.  The Prince Street branch building is being marketed for sale.
