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 23 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 6 . 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 7 , and the statements of income , comprehensive income , changes in shareholders’ equity and cash flows for the three months ended March 31, 2017 . Results for the three month period ended March 3 1 , 201 7 are not necessarily indicative of the results that may be expected for the year ending December 31, 201 7 . 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.  Recent Accounting Pronouncements In March 2017, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2017-08, Receivables—Nonrefundable Fees and Other Costs (Subtopic 310-20), Premium Amortization on Purchased Callable Debt Securities. The ASU shortens the amortization period for certain callable debt securities held at a premium to the earliest call date. Under current GAAP, entities normally amortize the premium as an adjustment of yield over the contractual life of the instrument. Stakeholders have expressed concerns with the current approach on the basis that current GAAP excludes certain callable debt securities from consideration of early repayment of principal even if the holder is certain that the call will be exercised. As a result, upon the exercise of a call on a callable debt security held at a premium, the unamortized premium is recorded as a loss in earnings. Further, there is diversity in practice (1) in the amortization period for premiums of callable debt securities, and (2) in how the potential for exercise of a call is factored into current impairment assessments. The ASU shortens the amortization period for certain callable debt securities held at a premium and requires the premium to be amortized to the earliest call date. However, the amendments do not require an accounting change for securities held at a discount; the discount continues to be amortized to maturity. The amendments are effective for public business entities for annual periods beginning after December 15, 2018, including interim periods within those annual periods. Early adoption is permitted. The Company is currently in compliance with this guidance; therefore, its adoption will have no impact on its financial statements. Also in March 2017, the FASB issued ASU No. 2017-07, Compensation — Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost . The amendments apply to all employers, including not-for-profit entities, that offer to their employees defined benefit pension plans, other postretirement benefit plans, or other types of benefits accounted for under Topic 715, Compensation — Retirement Benefits . The amendments require that an employer report the service cost component in the same line item or items as other compensation costs arising from services rendered by the pertinent employees during the period. The other components of net benefit cost are required to be presented in the income statement separately from the service cost component. The line item or items used in the income statement to present the other components of net benefit cost must be disclosed. The amendments are effective for public business entities for annual periods beginning after December 15, 2017, including interim periods within those annual periods. Early adoption is permitted as of the beginning of an annual period for which financial statements (interim or annual) have not been issued or made available for issuance. The Company does not expect the adoption of this guidance to have a material impact on its financial statements. The Company does not offer a post retirement benefit plan. As the Company’s pension plan is frozen, no additional service cost will be incurred. The remaining components of net periodic benefit cost are not expected to be significant. See Note 10 for further details.

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 three months ended March 3 1 , 201 7 and 201 6 were as follows (dollars in thousands) :      Three Months Ended  March 31, 2017 March 31, 2016  Gross realized gains $ 130 $ 754  Gross realized losses (35) (495)  Net securities gains $ 95 $ 259  In estimating other than temporary impairment (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 months ended March 3 1 , 201 7 and 201 6 .

The unrealized losses are from 147 securities at March 3 1 , 201 7 . Of those, 131 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. Sixteen investment grade corporate and other bond obligations comprise the remaining securities with unrealized losses at March 3 1 , 201 7 . 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 $72.3 million and $75.8 million at March 3 1 , 201 7 and December 31, 201 6 , respectively, were pledged to secure public deposits as required or permitted by law . Securities with amortized costs of $4.2 m illion and $4.4 million at March 3 1 , 201 7 and December 31, 201 6 , respectively, were pledged to secure lines of credit at the Federal Reserve discount window. At each of March 3 1 , 201 7 and December 31, 201 6 , 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 $ 718,000 and $ 749,000 at March 3 1 , 201 7 and December 31, 201 6 , 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 March 3 1 , 201 7 and December 31, 201 6 , the Company’s allowance for credit losses was comprised of the following: (i) a specific valuation component calculated in accordance with FASB ASC 310, Receivables, (ii) a general valuation component calculated in accordance with FASB Accounting Standards Codification (ASC) 450, Contingencies , based on historical loan loss experience, 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.

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 $15.7 million and $15.8 million at March 3 1 , 201 7 and December 31, 201 6 , 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 March 3 1 , 201 7 and December 31, 201 6 (dollars in thousands):     March 31, 2017  Pass Special Mention Substandard Doubtful Total  Mortgage loans on real estate:  Residential 1-4 family $ 203,046 $ 4,171 $ 3,300 $ — $ 210,517  Commercial 334,557 3,330 5,717 — 343,604  Construction and land development 91,659 189 4,304 — 96,152  Second mortgages 7,245 479 — — 7,724  Multifamily 46,883 — 2,586 — 49,469  Agriculture 7,224 113 112 — 7,449  Total real estate loans 690,614 8,282 16,019 — 714,915  Commercial loans 123,179 5,111 2,439 — 130,729  Consumer installment loans 5,256 23 42 — 5,321  All other loans 1,261 — — — 1,261  Total loans $ 820,310 $ 13,416 $ 18,500 $ — $ 852,226     December 31, 2016  Pass Special Mention Substandard Doubtful Total  Mortgage loans on real estate:  Residential 1-4 family $ 199,973 $ 4,612 $ 3,278 $ — $ 207,863  Commercial 330,851 3,168 5,785 — 339,804  Construction and land development 92,556 234 5,492 — 98,282  Second mortgages 7,474 437 — — 7,911  Multifamily 36,474 — 2,610 — 39,084  Agriculture 7,067 118 — — 7,185  Total real estate loans 674,395 8,569 17,165 — 700,129  Commercial loans 122,129 5,879 1,292 — 129,300  Consumer installment loans 5,563 20 44 — 5,627  All other loans 1,243 — — — 1,243  Total loans $ 803,330 $ 14,468 $ 18,501 $ — $ 836,299  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. The Company had 17 loans that met the definition of a TDR at each of March 3 1 , 201 7 and 201 6, respectively .  The Company had no loan modifications considered to be TDRs during the three months ended March 31, 2017. During the three months ended March 31, 2016, the Company modified one consumer installment loan that was considered to be a TDR. The Company extended the terms and lowered the interest rate for this loan, which had a pre- and post -modification balance of $248,000 .  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 months ended March 3 1 , 201 7 and 201 6 .  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 7 , the Company had 1-4 family mortgages in the amount of $149.4 million pledged to the Federal Home Loan Bank with a lendable collateral value of $135.0 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 7 and December 31, 201 6 , the outstanding contractual balance of the PCI loans was $78. 3 million and $81.1 million, respectively. The carrying amount, by loan type, as of these dates is as follows (dollars in thousands):      March 31, 2017 December 31, 2016  Amount % of PCI Loans Amount % of PCI Loans  Mortgage loans on real estate:  Residential 1-4 family $ 44,465 89.40 % $ 46,623 89.72 %  Commercial 622 1.25 649 1.25  Construction and land development 1,935 3.89 1,969 3.79  Second mortgages 2,450 4.93 2,453 4.72  Multifamily 266 0.53 270 0.52  Total real estate loans 49,738 100.00 51,964 100.00  Total PCI loans $ 49,738 100.00 % $ 51,964 100.00 %  There was no activity in the allowance for loan losses on PCI loans for the three months ended March 3 1 , 201 7 and 201 6 .  The following table presents information on the PCI loans collectively evaluated for impairment in the allowance for loan losses at March 3 1 , 201 7 and December 31, 201 6 (dollars in thousands):     March 31, 2017 December 31, 2016  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 $ 44,465 $ 200 $ 46,623  Commercial — 622 — 649  Construction and land development — 1,935 — 1,969  Second mortgages — 2,450 — 2,453  Multifamily — 266 — 270  Total real estate loans 200 49,738 200 51,964  Total PCI loans $ 200 $ 49,738 $ 200 $ 51,964           The change in the accretable yield balance for the three months ended March 3 1 , 201 7 and the year ended December 31, 201 6 , is as follows (dollars in thousands):       Balance, January 1, 2016 $ 49,128  Accretion (6,206)  Reclassification from nonaccretable yield 5,433  Balance, December 31, 2016 $ 48,355  Accretion (1,479)  Reclassification from nonaccretable yield 45  Balance, March 31, 2017 $ 46,921  The PCI loans were not classified as nonperforming assets as of March 3 1 , 201 7 , 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	N ote 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 7 .  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, 2017  Total Level 1 Level 2 Level 3  Investment securities available for sale  U.S. Treasury issue and other U.S. Gov’t agencies $ 48,954 $ 1,790 $ 47,164 $ -  U.S. Gov’t sponsored agencies 2,862 - 2,862 -  State, county and municipal 127,087 3,328 123,759 -  Corporate and other bonds 16,061 - 16,061 -  Mortgage backed – U.S. Gov’t agencies 3,476 - 3,476 -  Mortgage backed – U.S. Gov’t sponsored agencies 15,273 1,066 14,207 -  Total investment securities available for sale 213,713 6,184 207,529 -  Cash flow hedge $ 12 $ - $ 12 $ -  Total assets at fair value $ 213,725 $ 6,184 $ 207,541 $ -  Total liabilities at fair value $ - $ - $ - $ -        December 31, 2016  Total Level 1 Level 2 Level 3  Investment securities available for sale  U.S. Treasury issue and other U.S. Gov’t agencies $ 57,976 $ 11,055 $ 46,921 $ -  U.S. Gov’t sponsored agencies 3,336 952 2,384 -  State, county and municipal 122,773 2,345 120,428 -  Corporate and other bonds 15,503 - 15,503 -  Mortgage backed – U.S. Gov’t agencies 3,495 - 3,495 -  Mortgage backed – U.S. Gov’t sponsored agencies 13,038 - 13,038 -  Total investment securities available for sale 216,121 14,352 201,769 -  Total assets at fair value $ 216,121 $ 14,352 $ 201,769 $ -  Cash flow hedge $ (70) $ - $ (70) $ -  Total liabilities at fair value $ (70) $ - $ (70) $ -  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) . 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 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. 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 7 and December 31, 201 6 (dollars in thousands):     March 31, 2017  Total Level 1 Level 2 Level 3  Impaired loans $ 8,557 $ — $ 1,969 $ 6,588  Other real estate owned 3,569 — 1,995 1,574  Total assets at fair value $ 12,126 $ — $ 3,964 $ 8,162  Total liabilities at fair value $ — $ — $ — $ —     December 31, 2016  Total Level 1 Level 2 Level 3  Impaired loans $ 9,536 $ — $ 2,168 $ 7,368  Other real estate owned 4,427 — 3,408 1,019  Total assets at fair value $ 13,963 $ — $ 5,576 $ 8,387  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 7 and December 31, 201 6 , 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 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 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 7  Carrying Value Estimated Fair Value Level 1 Level 2 Level 3 Financial assets:  Securities held to maturity $46,500 $46,881 $ — $46,881 $ —  Loans, net of allowance 842,713 846,180 — 839,592 6,588  PCI loans, net of allowance 49,538 55,408 — — 55,408  Financial liabilities:  Interest bearing deposits 923,630 924,471 — 924,471 —  Long-term borrowings 85,816 85,711 — 85,711 —     December 31, 201 6  Carrying Value Estimated Fair Value Level 1 Level 2 Level 3 Financial assets:  Securities held to maturity $46,608 $46,858 $1,093 $45,765 $ —  Loans, net of allowance 826,806 829,349 — 821,981 7,368  PCI loans, net of allowance 51,764 57,100 — — 57,100  Financial liabilities:  Interest bearing deposits 908,407 909,627 — 909,627 —  Long-term borrowings 87,681 87,611 — 87,611 —  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 March 3 1 , 201 7 . 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 (Level 1) .  Securities held to maturity For securities held to maturity , fair values are based on quoted market prices or dealer quotes (Level 1 and 2) .  Restricted securities The carrying value of restricted securities approximates their fair value based on the redemption provisions of the respective issuer (Level 2) .  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.  PCI loans  Fair values for PCI 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.  Accrued interest receivable The carrying amounts of accrued interest receivable approximate fair value (Level 2) .  Financial Liabilities  Noninterest bearing deposits The carrying amount of noninterest bearing deposits approximates fair value (Level 2) .  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.  Federal funds purchased  The carrying amount of federal funds purchased approximates fair value (Level 2).  Long-term borrowings  The fair values of the Company’s long-term borrowings, such as FHLB advances and long-term debt, 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 (Level 2) .  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 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.  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.

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 7 and 201 6 (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 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   For the three months ended March 31, 2016  Basic EPS $ 2,420 21,873 $ 0.11  Effect of dilutive stock awards — 192 —  Diluted EPS $ 2,420 22,065 $ 0.11  There were no antidilutive exclusions from the computation of diluted earnings per common share for the three months ended March 31, 2017. Antidilutive common shares issuable under awards or options of 263,000 were excluded from the computation of diluted earnings per common share for the three months ended March 31, 2016.

Employee Benefit Plan [Abstract]
Employee Benefit Plan	  Note 1 0 . Employee Benefit Plan The Company adopted the Bank of Essex noncontributory, defined benefit pension plan for all full-time pre-merger Bank of Essex employees over 21 years of age. Benefits are generally based upon years of service and the employees’ compensation. The Company funds pension costs in accordance with the funding provisions of the Employee Retirement Income Security Act. The Company has frozen the plan benefits for all the defined benefit plan participants effective December 31, 2010.  The following table provides the components of net periodic benefit cost for the plan for the three months ended March 3 1 , 201 7 and 201 6 (dollars in thousands):       Three months ended  March 31, 2017 March 31, 2016  Interest cost $ 39 $48  Expected return on plan assets (70) (82)  Amortization of prior service cost 1 1  Recognized net loss due to settlement — 13  Recognized net actuarial loss 12 13  Net periodic benefit cost $ (18) $ (7)        In accordance with FASB ASC 715, Compensation-Retirement Benefits , settlement accounting is triggered when lump sum payments to plan participants exceed the sum of the plan’s service cost and interest cost for the year. The impact of settlement accounting is that a percentage of any outstanding losses that the plan is currently amortizing must be recognized immediately. This percentage is calculated as the ratio of lump sums paid to the total liability for the plan. This amount changes as plan participants retire during the year.

Cash Flow Hedge [Abstract]
Cash Flow Hedge	Note 1 1 . 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. T he Company had $390,000 of cash pledged as collateral for each of the periods ended March 31, 2017 and December 31, 2016. 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 31, 2017 and 2016 . T he fair value of the Company’s cash flow hedge was an unrealized gain of $12,000 and an unrealized loss of $70,000 at March 31, 2017 and December 31, 2016, respectively, and was recorded in other assets and other liabilities , respectively . The gain and loss were recorded as a component of other comprehensive income net of associated tax effects .
