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 26 full-service offices in Virginia and Maryland. The Bank also operates one loan production office in Virginia. 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. 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, 201 7 . 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 March 3 1 , 201 8 , the statements of income and comprehensive income for the three months ended March 3 1 , 201 8 , and the statements of changes in shareholders’ equity and cash flows for the three months ended March 3 1 , 201 8 . Results for the three month period ended March 3 1 , 201 8 are not necessarily indicative of the results that may be expected for the year ending December 31, 201 8 . 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 shareholder’s equity.

There were no investments held that had OTTI losses for the three months ended March 3 1 , 201 8 and 201 7 .

The unrealized losses are from 176 securities at March 3 1 , 201 8 . Of those, 169 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. Five investment grade asset-backed securities comprised of student loan pools included in corporate obligations and two corporate bond s make up the remaining securities with unrealized losses at March 3 1 , 201 8 . 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 $68.6 million and $71.7 million at March 3 1 , 201 8 and December 31, 201 7 , respectively, were pledged to secure public deposits as required or permitted by law. Securities with amortized costs of $7.0 million and $7.0 million at March 3 1 , 201 8 and December 31, 201 7 , respectively, were pledged to secure lines of credit at the Federal Reserve discount window. At each of March 3 1 , 201 8 and December 31, 201 7 , 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.

As these loans are 100% guaranteed by the USDA, no loan loss allowance is required. These loan balances included a purchase premium of $ 785,000 and $ 824,000 at March 3 1 , 201 8 and December 31, 201 7 , 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.

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 $17.7 million and $18.0 million at March 3 1 , 201 8 and December 31, 201 7 , 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 Company had 23 and 17 loans that met the definition of a TDR at March 3 1 , 201 8 and 201 7 , respectively.   The Company had no loan modifications considered to be TDRs during the three months ended March 3 1 , 201 8 and 2017 .  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 months ended March 3 1 , 201 8 and 201 7 .  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 March 3 1 , 201 8 , the Company had 1-4 family mortgages in the amount of $137.1 million pledged to the Federal Home Loan Bank with a lendable collateral value of $110.3 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 March 3 1 , 201 8 and December 31, 201 7 , the outstanding contractual balance of the PCI loans was $68.2 million and $71.0 million, respectively. The carrying amount, by loan type, as of these dates is as follows (dollars in thousands):      March 31, 2018 December 31, 2017  Amount % of PCI Loans Amount % of PCI Loans  Mortgage loans on real estate:  Residential 1-4 family $ 37,980 89.97 % $ 39,805 89.79 %  Commercial 503 1.19 547 1.23  Construction and land development 1,526 3.61 1,588 3.58  Second mortgages 1,953 4.63 2,136 4.82  Multifamily 253 0.60 257 0.58  Total real estate loans 42,215 100.00 44,333 100.00  Total PCI loans $ 42,215 100.00 % $ 44,333 100.00 %  There was no activity in the allowance for loan losses on PCI loans for the three months ended March 3 1 , 201 8 and 201 7 .  The following table presents information on the PCI loans collectively evaluated for impairment in the allowance for loan losses at March 3 1 , 201 8 and December 31, 201 7 (dollars in thousands):     March 31, 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 $ 200 $ 37,980 $ 200 $ 39,805  Commercial — 503 — 547  Construction and land development — 1,526 — 1,588  Second mortgages — 1,953 — 2,136  Multifamily — 253 — 257  Total real estate loans 200 42,215 200 44,333  Total PCI loans $ 200 $ 42,215 $ 200 $ 44,333   The change in the accretable yield balance for the three months ended March 3 1 , 201 8 and the year ended December 31, 201 7 , 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 (1,397)  Reclassification to nonaccretable difference (113)  Balance, March 31, 2018 $ 42,616    The PCI loans were not classified as nonperforming assets as of March 3 1 , 201 8 , 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 March 3 1 , 201 8 .  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):      March 31, 2018  Total Level 1 Level 2 Level 3  Investment securities available for sale  U.S. Treasury issue and other U.S. Gov’t agencies $ 37,601 $ - $ 37,601 $ -  U.S. Gov’t sponsored agencies 9,227 - 9,227 -  State, county and municipal 123,574 1,468 122,106 -  Corporate and other bonds 7,814 - 7,814 -  Mortgage backed – U.S. Gov’t agencies 5,272 - 5,272 -  Mortgage backed – U.S. Gov’t sponsored agencies 18,677 1,046 17,631 -  Total investment securities available for sale 202,165 2,514 199,651 -  Cash flow hedge 363 - 363 -  Total assets at fair value $ 202,528 $ 2,514 $ 200,014 $ -  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 $ 40,256 $ - $ 40,256 $ -  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 5,442 - 5,442 -  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 March 31, 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 March 3 1 , 201 8 and December 31, 201 7 (dollars in thousands):     March 31, 2018  Total Level 1 Level 2 Level 3  Impaired loans $ 8,983 $ — $ 1,716 $ 7,267  Bank premises and equipment held for sale 525 — — 525  Other real estate owned 3,166 — 1,183 1,983  Total assets at fair value $ 12,674 $ — $ 2,899 $ 9,775  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 March 3 1 , 201 8 and December 31, 201 7 , 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, 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. 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 property, 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):    March 3 1 , 201 8  Carrying Value Estimated Fair Value Level 1 Level 2 Level 3 Financial assets:  Securities held to maturity $44,534 $44,578 $ — $44,578 $ —  Loans, net of allowance 955,343 961,245 — 961,245  PCI loans, net of allowance 42,015 46,345 — — 46,345  Financial liabilities:  Interest bearing deposits 946,283 945,267 — 945,267 —  Long-term borrowings 105,185 104,859 — 104,859 —     December 31, 201 7  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 —  Long-term 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 months ended March 3 1 , 201 8 and 201 7 (dollars and shares in thousands, except per share data):    Net Income (Loss) (Numerator) Weighted Average Common Shares (Denominator) Per Common Share Amount  For the three months ended March 31, 2018  Basic EPS $ 2,594 22,076 $ 0.12  Effect of dilutive stock awards — 445 —  Diluted EPS $ 2,594 22,521 $ 0.12   For the three months ended March 31, 2017  Basic EPS $ 2,493 21,962 $ 0.11  Effect of dilutive stock awards — 471 —  Diluted EPS $ 2,493 22,433 $ 0.11  Antidilutive common shares issuable under awards or options of 279,000 were excluded from the computation of diluted earnings per common share for the three months ended March 31, 2018. There were no antidilutive exclusions from the computation of diluted earnings per common share for the three months ended March 3 1 , 201 7 .

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 March 3 1 , 201 8 and December 31, 201 7, 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 months ended March 3 1 , 201 8 and 201 7 . The fair value of the Company’s cash flow hedge was an unrealized gain of $363,000 and $177,000 at March 3 1 , 201 8 and December 31, 2017, respectively, and was recorded in other assets. The gain w as recorded as a component of other comprehensive income net of associated tax effects. 

Revenue Recognition

Revenue from Contract with Customer [Abstract]
Revenue Recognition	Note 12 . Revenue Recognition  On January 1, 2018, the Company adopted 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 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 consists of other recurring revenue streams such as commissions from sales of mutual funds and other investments to its customers by a third - party service provider and investment advisor fees. The Company receive s 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 months ended March 31, 2018 and 2017 (dollars in thousands):      Three months ended  March 31, 2018 March 31, 2017  Noninterest income  In-scope of Topic 606:  Service charges on deposit accounts $ 391 $ 370  Interchange fees 190 155  Brokerage fees and commissions 61 80  Noninterest income (in-scope of Topic 606) 642 605  Noninterest income (out-of-scope of Topic 606) 440 430  Total noninterest income $ 1,082 $ 1,035
