Organization, Consolidation and Presentation of Financial Statements [Abstract]
Nature of Banking Activities and Significant Accounting Policies	Nature of Banking Activities and Significant Accounting Policies Eagle Financial Services, Inc. (the “Company” or “Corporation”) and Subsidiary grant commercial, financial, agricultural, residential and consumer loans to customers in Virginia and the Eastern Panhandle of West Virginia. The loan portfolio is well diversified and generally is collateralized by assets of the customers. The loans are expected to be repaid from cash flows or proceeds from the sale of selected assets of the borrowers. The accounting and reporting policies of the Company conform to accounting principles generally accepted in the United States of America and to accepted practices within the banking industry. Principles of Consolidation The Company owns 100% of Bank of Clarke County (the “Bank”). The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiary. All significant intercompany accounts and transactions between the Company and the Bank have been eliminated. Trust Assets Eagle Investment Group (“EIG”), as a division of the Bank offers both a trust department and investment services. The trust services division of EIG offers a full range of personal and retirement plan services, which include serving as agent for bill paying and custody of assets, as investment manager with full authority or advisor, as trustee or co-trustee for trusts under will or under agreement, as trustee of life insurance trusts, as guardian or committee, as agent under a power of attorney, as executor or co-executor for estates, as custodian or investment advisor for individual retirement plans, and as trustee or trust advisor for corporate retirement plans such as profit sharing and 401(k) plans. The brokerage division of EIG offers a full range of investment services, which include tax-deferred annuities, IRAs and rollovers, mutual funds, retirement plans, 529 college savings plans, life insurance, long term care insurance, fixed income investing, brokerage CDs, and full service or discount brokerage services. Securities and other property held by the Eagle Investment Group in a fiduciary or agency capacity are not assets of the Company and are not included in the accompanying consolidated financial statements. Cash and Cash Equivalents For purposes of reporting cash flows, cash and cash equivalents include cash on hand, amounts due from banks, federal funds sold, and interest bearing deposits. Generally, federal funds are purchased and sold for one-day periods. Securities Debt securities that management has the positive intent and ability to hold to maturity are classified as “held to maturity” and recorded at amortized cost. Securities not classified as held to maturity, including equity securities with readily determinable fair values, are classified as “available for sale” and recorded at fair value, with unrealized gains and losses excluded from earnings and reported in other comprehensive income. Purchase premiums and discounts are recognized in interest income using the interest method over the terms of the securities. Declines in the fair value of held to maturity and available for sale securities below their cost that are deemed to be “other than temporary” are reflected in earnings as realized losses. In estimating “other than temporary” impairment losses, management considers (1) the length of time and the extent to which the fair value has been less than cost, (2) the financial condition and near-term prospects of the issuer, and (3) the intent and ability of the Company to retain its investment in the issuer for a period of time sufficient to allow for any anticipated recovery of fair value. Gains and losses on the sale of securities are recorded on the trade date and are determined using the specific identification method. The Bank is required to maintain an investment in the capital stock of certain correspondent banks. No readily available market exists for this stock and it has no quoted market value. The investment in these securities is recorded at cost and they are reported on the Company’s consolidated balance sheet as restricted investments. Loans The Company grants mortgage, commercial and consumer loans to customers. A substantial portion of the loan portfolio is represented by mortgage loans throughout the Counties of Clarke, Frederick, and Loudoun, Virginia and the City of Winchester, Virginia. The ability of the Company’s debtors to honor their contracts is dependent upon the real estate and general economic conditions in this area. Loans that management has the intent and ability to hold for the foreseeable future or until maturity or pay-off generally are reported at their outstanding unpaid principal balances adjusted for the allowance for loan losses. Interest income is accrued on the unpaid principal balance. Loan fees collected and certain costs incurred related to loan originations are deferred and amortized as an adjustment to interest income over the life of the related loans. Deferred fees and costs are recorded as an adjustment to interest income using a method that approximates a constant yield. The accrual of interest on mortgage and commercial loans is discontinued at the time the loan is 120 and 90 days delinquent, respectively, unless the credit is well-secured and in process of collection. Credit card loans and other personal loans are typically charged off no later than 180 days past due. Past due status is based on the contractual terms of the loan. In all cases, loans are placed on nonaccrual or charged-off at an earlier date if collection of principal and interest is considered doubtful. All interest accrued but not collected for loans that are placed on nonaccrual or charged off is reversed against interest income. The interest on these loans is accounted for on the cash-basis or cost-recovery method, until qualifying for return to accrual. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured. Troubled Debt Restructurings (TDR) In situations where, for economic or legal reasons related to a borrower’s financial condition, management may grant a concession to the borrower that it would not otherwise consider, the related loan is classified as a TDR. TDRs are considered impaired loans. Upon designation as a TDR, the Company evaluates the borrower’s payment history, past due status and ability to make payments based on the revised terms of the loan. If a loan was accruing prior to being modified as a TDR and if the Company concludes that the borrower is able to make such payments, and there are no other factors or circumstances that would cause it to conclude otherwise, the loan will remain on an accruing status. If a loan was on non-accrual status at the time of the TDR, the loan will remain on non-accrual status following the modification and may be returned to accrual status based on the policy for returning loans to accrual status as noted above. Risks by Loan Portfolio Segments One-to-Four-Family Residential Real Estate Lending Residential mortgage loans generally are made on the basis of the borrower’s ability to make repayment from employment and other income and are secured by real estate whose value tends to be readily ascertainable. As part of the application process, information is gathered concerning income, employment and credit history of the applicant. The valuation of residential collateral is provided by independent fee appraisers who have been approved by the Bank’s Directors Loan Committee. Commercial Real Estate Lending Commercial real estate lending entails significant additional risk as compared with residential mortgage lending. Commercial real estate loans typically involve larger loan balances concentrated with single borrowers or groups of related borrowers. Additionally, the repayment of loans secured by income producing properties is typically dependent on the successful operation of a business or a real estate project and thus may be subject, to a greater extent, to adverse conditions in the real estate market or the economy, in general. Construction and Land Development Lending There are two characteristics of construction lending which impact its overall risk as compared to residential mortgage lending. First, there is more concentration risk due to the extension of a large loan balance through several lines of credit to a single developer or contractor. Second, there is more collateral risk due to the fact that loan funds are provided to the borrower based upon the estimated value of the collateral after completion. This could cause an inaccurate estimate of the amount needed to complete construction or an excessive loan-to-value ratio. To mitigate the risks associated with construction lending, the Bank generally limits loan amounts to 80% of the estimated appraised value of the finished home. Commercial and Industrial Lending Commercial business loans generally have more risk than residential mortgage loans, but have higher yields. To manage these risks, the Bank generally obtains appropriate collateral and personal guarantees from the borrower’s principal owners and monitors the financial condition of the borrower. Commercial business loans typically are made on the basis of the borrower’s ability to make repayment from cash flow from its business and are secured by business assets, such as commercial real estate, accounts receivable, equipment and inventory. As a result, the availability of funds for the repayment of commercial business loans is substantially dependent on the success of the business itself. Furthermore, the collateral for commercial business loans may depreciate over time and generally cannot be appraised with as much precision as residential real estate. Consumer Lending Consumer loans generally entail greater risk than residential mortgage loans, particularly in the case of consumer loans which are unsecured or secured by rapidly depreciable assets such as automobiles. In such cases, any repossessed collateral on a defaulted consumer loan may not provide an adequate source of repayment of the outstanding loan balance as a result of the greater likelihood of damage, loss or depreciation. Allowance for Loan Losses The allowance for loan losses is established as losses are estimated to have occurred through a provision for (recovery of) loan losses charged to earnings. Loan losses are charged against the allowance when management believes the uncollectability of a loan balance is confirmed. Subsequent recoveries, if any, are credited to the allowance. The allowance for loan losses is evaluated on a regular basis by management and is based upon management’s periodic review of the collectability of the loans in light of historical experience, the nature and volume of the loan portfolio, adverse situations that may affect the borrower’s ability to repay, estimated value of any underlying collateral and prevailing economic conditions. This evaluation is inherently subjective as it requires estimates that are susceptible to significant revision as more information becomes available. The allowance consists of specific, general and unallocated components. The specific component relates to loans that are impaired. An allowance is established when the discounted cash flows (or collateral value or observable market price) of the impaired loan is lower than the carrying value of that loan. The general component covers non-impaired loans and is based on historical loss experience and other qualitative factors. Other qualitative factors considered in the general component include the levels and trends in delinquencies and nonperforming loans, trends in volume and terms of loans, the effects of any changes in lending policies, the experience, ability, and depth of management, national and local economic trends and conditions, concentrations of credit, the quality of the Company’s loan review system, competition and regulatory requirements. An unallocated component is maintained to cover uncertainties that could affect management’s estimate of probable losses. The unallocated component of the allowance reflects the margin of imprecision inherent in the underlying assumptions used in the methodologies for estimating specific and general losses in the portfolio. A loan is considered impaired when, based on current information and events, it is probable that the Company will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement. Factors considered by management in determining impairment include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record, and the amount of the shortfall in relation to the principal and interest owed. Impairment is measured on a loan-by-loan basis for commercial and construction loans by either the present value of expected future cash flows discounted at the loan’s effective interest rate, the loan’s obtainable market price, or the fair market value less estimated liquidation costs of the collateral if the loan is collateral dependent. Large groups of smaller balance homogeneous loans are collectively evaluated for impairment. Accordingly, the Company does not separately identify individual consumer and residential loans for impairment disclosures, unless such loans are the subject of a restructuring agreement. Bank Premises and Equipment Land is carried at cost. Buildings and equipment are carried at cost, less accumulated depreciation computed on the straight-line method over the estimated useful lives of the assets. Estimated useful lives range from 10 to 39 years for buildings and 3 to 10 years for furniture and equipment. Other Real Estate Owned Assets acquired through, or in lieu of, loan foreclosure are held for sale and are initially recorded at the fair value of the property, less estimated selling costs at the date of foreclosure. Any write-downs based on the asset’s fair value at the date of acquisition are charged to the allowance for loan losses. After foreclosure, valuations are periodically performed by management and property held for sale is carried at the lower of the new cost basis or fair value less estimated cost to sell. Impairment losses on property to be held and used are measured as the amount by which the carrying amount of a property exceeds its fair value. Costs of significant property improvements are capitalized, whereas costs relating to holding property are expensed. The portion of interest costs relating to development of real estate is capitalized. Valuations are periodically performed by management, and any subsequent write-downs are recorded as a charge to operations, if necessary, to reduce the carrying value of a property to the lower of its cost or fair value less cost to sell. Revenue and expenses from operations and changes in the valuation allowance are included in the net expenses from foreclosed assets. Retirement Plans The Company sponsors a 401(k) savings plan under which eligible employees may defer a portion of their compensation on a pretax basis. The Company also provides a match to participants in this plan, as described more fully in Note 12. Stock-Based Compensation Plan During 2014, the Company’s shareholders approved a stock incentive plan which allows key employees and directors to increase their personal financial interest in the Company. This plan permits the issuance of incentive stock options and non-qualified stock options and the award of stock appreciation rights, common stock, restricted stock, and phantom stock. The plan, as adopted, authorized the issuance of up to 500,000 shares of common stock. This plan is discussed more fully in Note 11. Income Taxes Deferred income tax assets and liabilities are determined using the liability (or balance sheet) method. Under this method, the net deferred tax asset or liability is determined based on the tax effects of the temporary differences between the book and tax bases of the various assets and liabilities and gives current recognition to changes in tax rates and laws. When tax returns are filed, it is likely that some positions taken would be sustained upon examination by the applicable taxing authority, while others are subject to uncertainty about the merits of the position taken or the amount of the position that would be ultimately sustained. The benefit of a tax position is recognized in the financial statements in the period during which, based on all available evidence, the Company believes it is “more likely than not” that the position will be sustained upon examination, including the resolution of appeals or litigation processes, if any. Tax positions taken are not offset or aggregated with other positions. Tax positions that meet the “more likely than not” recognition threshold are measured as the largest amount of tax benefit that is more than fifty percent ( 50% ) likely of being realized upon settlement with the applicable taxing authority. The portion of the benefits associated with tax positions taken that exceeds the amount measured as described above is reflected as a liability for unrecognized tax benefits in the balance sheet along with any associated interest and penalties that would be payable to the applicable taxing authority upon examination. Interest and penalties associated with unrecognized tax benefits are classified as additional income taxes in the statement of income. The Company has no uncertain tax positions. Advertising The Company follows the policy of charging the costs of advertising to expense as incurred. Reclassifications Certain reclassifications have been made to the 2016 financial statements to conform to reporting for 2017 . The results of the reclassifications are not considered material and had no effect on prior years' net income or shareholders' equity. Earnings Per Common Share Basic earnings per share represents income available to common shareholders divided by the weighted average number of common shares outstanding during the period. Nonvested restricted shares are included in the weighted average number of common shares used to compute basic earnings per share because of dividend participation and voting rights. Diluted earnings per share reflects additional common shares that would have been outstanding if dilutive potential common shares had been issued, as well as any adjustment to income that would result from the assumed issuance. The number of potential common shares is determined using the treasury method. The following table shows the weighted average number of shares used in computing earnings per share and the effect on the weighted average number of shares of dilutive potential common stock. 2017 2016 2015 Weighted average number of common shares outstanding used to calculate basic earnings per share 3,468,275 3,518,848 3,495,334 Effect of dilutive common stock — — — Weighted average number of common shares outstanding used to calculate diluted earnings per share 3,468,275 3,518,848 3,495,334 There were no potentially dilutive securities outstanding in 2017 , 2016 or 2015 . Comprehensive Income Accounting principles generally accepted in the United States of America require that recognized revenue, expenses, gains and losses be included in net income. Certain changes in assets and liabilities, net of income taxes, are reported within the balance sheet as a separate component of shareholders’ equity. These changes, along with net income, are components of comprehensive income and are reported in the statement of comprehensive income. In addition to net income, the Company’s comprehensive income includes changes in the benefit obligations and plan assets for postretirement benefit plans, unrealized gains or losses on interest rate swaps, and unrealized gains or losses on available for sale securities. Derivative Financial Instruments The Company follows GAAP to account for derivative and hedging activities. Accordingly, a derivative is recognized in the balance sheet at its fair value. The fair value of a derivative is determined by quoted market prices and mathematical models using current and historical data. If certain hedging criteria are met, including testing for hedge effectiveness, special hedge accounting may be applied. The Company assesses each hedge, both at inception and on an ongoing basis, to determine whether the derivative used in a hedging transaction is effective in offsetting changes in the fair value or cash flows of the hedged item and whether the derivative is expected to remain effective during subsequent periods. The Company discontinues hedge accounting when (a) it determines that a derivative is no longer effective in offsetting changes in fair value or cash flows of a hedged item; (b) the derivative expires or is sold, terminated or exercised; (c) probability exists that the forecasted transaction will no longer occur or (d) management determines that designating the derivative as a hedging instrument is no longer appropriate. When hedge accounting is discontinued and a derivative remains outstanding, the Company recognizes the derivative in the balance sheet at its fair value and changes in the fair value are recognized in net income. At inception, the Company designates a derivative as (a) a fair value hedge of recognized assets or liabilities or of unrecognized firm commitments (fair-value hedge) or (b) a hedge of forecasted transactions or variable cash flows to be received or paid in conjunction with recognized assets or liabilities (cash-flow hedge). For a derivative treated as a fair-value hedge, a change in fair value is recorded as an adjustment to the hedged item and recognized in net income. For a derivative treated as a cash flow hedge, the effective portion of a change in fair value is recorded as an adjustment to the hedged item and recognized as a component of accumulated other comprehensive income (loss) within shareholders’ equity. For a derivative treated as a cash flow hedge, the ineffective portion of a change in fair value is recorded as an adjustment to the hedged item and recognized in net income. For more information on derivative financial instruments see Note 14 to the Consolidated Financial Statements. Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for loan losses, valuation of other real estate owned, and the evaluation for other-than-temporary impairment of investment securities. Stock Repurchase Program On June 21, 2017 , the Corporation renewed the stock repurchase program to repurchase up to 150,000 shares of its common stock prior to June 30, 2018 . During 2017 , the Company purchased 52,936 shares of its Common Stock under its stock repurchase program at an average price of $29.54 . During 2016 , the Company purchased 89,607 shares of its Common Stock under its stock repurchase program at an average price of $23.92 . All of these shares we retired. There was no repurchase activity during 2015 . The maximum number of shares that may yet be purchased under the plan as of December 31, 2017 are 111,115 . Recent Accounting Pronouncements In May 2014, the FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers: Topic 606.” This ASU revised guidance for the recognition, measurement, and disclosure of revenue from contracts with customers. The original guidance has been amended through subsequent accounting standard updates that resulted in technical corrections, improvements, and a one-year deferral of the effective date to January 1, 2018. The guidance, as amended, is applicable to all entities and, once effective, will replace significant portions of existing industry and transaction-specific revenue recognition rules with a more principles-based recognition model. Most revenue associated with financial instruments, including interest income, loan origination fees, and credit card fees, is outside the scope of the guidance. Gains and losses on investment securities, derivatives, and sales of financial instruments are similarly excluded from the scope. Entities can elect to adopt the guidance either on a full or modified retrospective basis. Full retrospective adoption will require a cumulative effect adjustment to retained earnings as of the beginning of the earliest comparative period presented. Modified retrospective adoption will require a cumulative effect adjustment to retained earnings as of the beginning of the reporting period in which the entity first applies the new guidance. The Company plans to adopt this guidance on the effective date, January 1, 2018 via the modified retrospective approach. The Company has completed its assessment of the adoption of this ASU, noting the standard will result in expanded disclosures related to non-interest income and enhance the qualitative disclosures on the revenues within the scope of the new guidance. The Company has concluded the adoption of ASU 2014-09 will not have a material impact on its consolidated financial statements. In January 2016, the FASB issued ASU 2016-01, “Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities.” The amendments in ASU 2016-01, among other things: 1) Requires equity investments (except those accounted for under the equity method of accounting, or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income. 2) Requires public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes. 3) Requires separate presentation of financial assets and financial liabilities by measurement category and form of financial asset (i.e., securities or loans and receivables). 4) Eliminates the requirement for public business entities to disclose the method(s) and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost. The amendments in this ASU are effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. This ASU has been discussed with the Company's current vendor to address updated disclosure requirements of 2016-01. The Company does not expect the adoption of ASU 2016-01 to have a material impact on its consolidated financial statements. In February 2016, the FASB issued ASU No. 2016-02, “Leases (Topic 842).” Among other things, in the amendments in ASU 2016-02, lessees will be required to recognize the following for all leases (with the exception of short-term leases) at the commencement date: (1) A lease liability, which is a lessee‘s obligation to make lease payments arising from a lease, measured on a discounted basis; and (2) A right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. Under the new guidance, lessor accounting is largely unchanged. Certain targeted improvements were made to align, where necessary, lessor accounting with the lessee accounting model and Topic 606, Revenue from Contracts with Customers. The amendments in this ASU are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early application is permitted upon issuance. Lessees (for capital and operating leases) and lessors (for sales-type, direct financing, and operating leases) must apply a modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. The modified retrospective approach would not require any transition accounting for leases that expired before the earliest comparative period presented. Lessees and lessors may not apply a full retrospective transition approach. The Company is currently assessing the impact that ASU 2016-02 will have on its consolidated financial statements. The Company has been gathering the lease agreement data and has begun to analyze the monetary impact to the consolidated financial statements. At December 31, 2017, the Company had only one lease. In June 2016, the FASB issued ASU No. 2016-13, “Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments.” The amendments in this ASU, among other things, require the measurement of all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. Financial institutions and other organizations will now use forward-looking information to better inform their credit loss estimates. Many of the loss estimation techniques applied today will still be permitted, although the inputs to those techniques will change to reflect the full amount of expected credit losses. In addition, the ASU amends the accounting for credit losses on available-for-sale debt securities and purchased financial assets with credit deterioration. The amendments in this ASU are effective for SEC filers for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. The Company is currently assessing the impact that ASU 2016-13 will have on its consolidated financial statements. The Company formed a CECL committee during 2016 which continues to meet monthly to address the compliance requirements. Historic loan data is currently being gathered and reviewed for completeness and accuracy. In addition, the committee is in the process of selecting a model that will assist in calculating the financial impact of ASU 2016-13 and anticipates running parallel allowance models under the current and new standard well in advance of the required implementation date. In August 2016, the FASB issued ASU No. 2016-15, “Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments”, to address diversity in how certain cash receipts and cash payments are presented and classified in the statement of cash flows. The amendments are effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. The amendments should be applied using a retrospective transition method to each period presented. If retrospective application is impractical for some of the issues addressed by the update, the amendments for those issues would be applied prospectively as of the earliest date practicable. Early adoption is permitted, including adoption in an interim period. The Company does not expect the adoption of ASU 2016-15 to have a material impact on its consolidated financial statements. In January 2017, the FASB issued ASU No. 2017-01, “Business Combinations (Topic 805): Clarifying the Definition of a Business”. The amendments in this ASU clarify the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. Under the current implementation guidance in Topic 805, there are three elements of a business-inputs, processes, and outputs. While an integrated set of assets and activities (collectively referred to as a “set”) that is a business usually has outputs, outputs are not required to be present. In addition, all the inputs and processes that a seller uses in operating a set are not required if market participants can acquire the set and continue to produce outputs. The amendments in this ASU provide a screen to determine

During the twelve months ended December 31, 2015 , the Company sold $3.7 million in available for sale securities with gross gains of $124 thousand . The fair value and gross unrealized losses for securities available for sale, totaled by the length of time that individual securities have been in a continuous gross unrealized loss position, at December 31, 2017 and 2016 were as follows: Less than 12 months 12 months or more Total Fair Value Gross Unrealized Losses Fair Value Gross Unrealized Losses Fair Value Gross Unrealized Losses December 31, 2017 (in thousands) Obligations of U.S. government corporations and agencies $ 4,455 $ 58 $ 7,810 $ 200 $ 12,265 $ 258 Mortgage-backed securities 11,885 59 17,931 287 29,816 346 Obligations of states and political subdivisions 4,071 27 4,692 159 8,763 186 $ 20,411 $ 144 $ 30,433 $ 646 $ 50,844 $ 790 December 31, 2016 (in thousands) Obligations of U.S. government corporations and agencies $ 19,129 $ 279 $ — $ — $ 19,129 $ 279 Mortgage-backed securities 28,013 456 — — 28,013 456 Obligations of states and political subdivisions 16,823 592 — — 16,823 592 $ 63,965 $ 1,327 $ — $ — $ 63,965 $ 1,327 Gross unrealized losses on available for sale securities included fifty-four ( 54 ) and eighty ( 80 ) debt securities at December 31, 2017 and December 31, 2016 , respectively. The Company evaluates securities for other-than-temporary impairment on at least a quarterly basis, and more frequently when economic or market concerns warrant such evaluation. The Company’s mortgage-backed securities are issued by U.S. government agencies, which guarantee payments to investors regardless of the status of the underlying mortgages. Consideration is given to the length of time and the amount of an unrealized loss, the financial condition of the issuer, and the intent and ability of the Company to retain its investment in the issuer long enough to allow for an anticipated recovery in fair value. The fair value of a security reflects its liquidity as compared to similar instruments, current market rates on similar instruments, and the creditworthiness of the issuer. Absent any change in the liquidity of a security or the creditworthiness of the issuer, prices will decline as market rates rise and vice-versa. The primary cause of the unrealized losses at December 31, 2017 and December 31, 2016 was changes in market interest rates. Since the losses can be primarily attributed to changes in market interest rates and not expected cash flows or an issuer’s financial condition, the unrealized losses are deemed to be temporary and management does not intend to sell and it is unlikely that management will be required to sell the securities prior to their anticipated recovery. The Company monitors the financial condition of these issuers continuously and will record other-than-temporary impairment if the recovery of value is unlikely. The Company’s securities are exposed to various risks, such as interest rate, market, currency and credit risks. Due to the level of risk associated with certain securities and the level of uncertainty related to changes in the value of securities, it is at least reasonably possible that changes in risks in the near term would materially affect securities reported in the financial statements. In addition, recent economic uncertainty and market events have led to unprecedented volatility in currency, commodity, credit and equity markets culminating in failures of some banking and financial services firms and government intervention to solidify others. These events underscore the level of investment risk associated with the current economic environment, and accordingly the level of risk in the Company’s securities. Securities having a carrying value of $2.6 million at December 31, 2017 were pledged for various purposes required by law.

For the year ended December 31, 2015 , the average recorded investment of impaired loans was $14.4 million . The interest income recognized on impaired loans was $404 thousand in 2015 . When the ultimate collectability of the total principal of an impaired loan is in doubt and the loan is in nonaccrual status, all payments are applied to principal under the cost-recovery method. For financial statement purposes, the recorded investment in nonaccrual loans is the actual principal balance reduced by payments that would otherwise have been applied to interest. When reporting information on these loans to the applicable customers, the unpaid principal balance is reported as if payments were applied to principal and interest under the original terms of the loan agreements. Therefore, the unpaid principal balance reported to the customer would be higher than the recorded investment in the loan for financial statement purposes. When the ultimate collectability of the total principal of the impaired loan is not in doubt and the loan is in nonaccrual status, contractual interest is credited to interest income when received under the cash-basis method. The Company uses a rating system for evaluating the risks associated with non-consumer loans. Consumer loans are not evaluated for risk unless the characteristics of the loan fall within classified categories. Descriptions of these ratings are as follows: Pass Pass loans exhibit acceptable history of profits, cash flow ability and liquidity. Sufficient cash flow exists to service the loan. All obligations have been paid by the borrower in an as agreed manner. Pass Monitored Pass monitored loans may be experiencing income and cash volatility, inconsistent operating trends, nominal liquidity and/or a leveraged balance sheet. A higher level of supervision is required for these loans as the potential for a negative event could impact the borrower’s ability to repay the loan. Special mention Special mention loans exhibit negative trends and potential weakness that, if left uncorrected, may negatively affect the borrower’s ability to repay its obligations. The risk of default is not imminent and the borrower still demonstrates sufficient financial strength to service debt. Substandard Substandard loans exhibit well defined weaknesses resulting in a higher probability of default. The borrowers exhibit adverse financial trends and a diminishing ability or willingness to service debt. Doubtful Doubtful loans exhibit all of the characteristics inherent in substandard loans; however given the severity of weaknesses, the collection of 100% of the principal is unlikely under current conditions. Loss Loss loans are considered uncollectible over a reasonable period of time and of such little value that its continuance as a bankable asset is not warranted.

Troubled Debt Restructuring Note, Debtor [Abstract]
Troubled Debt Restructurings	Troubled Debt Restructurings All loans deemed a troubled debt restructuring, or “TDR”, are considered impaired, and are evaluated for collateral and cash-flow sufficiency. A loan is considered a TDR when the Company, for economic or legal reasons related to a borrower’s financial difficulties, grants a concession to the borrower that the Company would not otherwise consider. All of the following factors are indicators that the Bank has granted a concession (one or multiple items may be present): • The borrower receives a reduction of the stated interest rate to a rate less than the institution is willing to accept at the time of the restructure for a new loan with comparable risk. • The borrower receives an extension of the maturity date or dates at a stated interest rate lower than the current market interest rate for new debt with similar risk characteristics. • The borrower receives a reduction of the face amount or maturity amount of the debt as stated in the instrument or other agreement. • The borrower receives a deferral of required payments (principal and/or interest). • The borrower receives a reduction of the accrued interest. There were twenty-one ( 21 ) troubled debt restructured loans totaling $4.4 million at December 31, 2017 . At December 31, 2016 , there were twenty-six ( 26 ) troubled debt restructured loans totaling $7.3 million . One loan, totaling $44 thousand , was in nonaccrual status at December 31, 2017 .

During the twelve months ended December 31, 2016 , the Company restructured five loans by granting concessions to borrowers experiencing financial difficulties. One residential loan and one commercial real estate loan was modified by extending the amortization period and reducing the interest rate. Two residential loans were modified by reducing the payments to be affordable for the borrower. One residential loan was modified by changing payments to interest-only in order to reduce the monthly payment for a period of time. During the twelve months ended December 31, 2015 , the Company restructured three loans by granting concessions to borrowers experiencing financial difficulties. Two single family residential loans were modified by changing the amortization period. One single family residential loan was modified by changing the amortization period and interest rate in order to reduce the monthly payments.

Income Taxes	Income Taxes The Company files income tax returns with the United States of America,the Commonwealth of Virginia and West Virginia. With few exceptions, the Company is no longer subject to federal, state, or local income tax examinations for years prior to 2014. The net deferred tax asset at December 31, 2017 and 2016 consisted of the following components: December 31, 2017 2016 (in thousands) Deferred tax assets: Allowance for loan losses $ 922 $ 1,525 Deferred compensation 72 117 Accrued postretirement benefits 23 40 Home equity origination costs 46 73 Nonaccrual interest 101 151 Securities available for sale — 32 Other 53 193 $ 1,217 $ 2,131 Deferred tax liabilities: Property and equipment $ 506 $ 814 Securities available for sale 71 — $ 577 $ 814 Net deferred tax asset $ 640 $ 1,317 The Company has not recorded a valuation allowance for deferred tax assets because management believes that it is more likely than not that they will be ultimately realized. Income tax expense for the years ended December 31, 2017 , 2016 and 2015 consisted of the following components: December 31, 2017 2016 2015 (in thousands) Current tax expense $ 3,094 $ 2,346 $ 2,001 Deferred tax expense 135 207 432 Deferred tax adjustment for enacted rate change 397 — — $ 3,626 $ 2,553 $ 2,433 The following table reconciles income tax expense to the statutory federal corporate income tax amount, which was calculated by applying the federal corporate income tax rate to pre-tax income for the years ended December 31, 2017 , 2016 and 2015 . December 31, 2017 2016 2015 (in thousands) Statutory federal corporate tax amount $ 3,880 $ 3,034 $ 3,172 Tax-exempt interest (income) (417 ) (387 ) (404 ) Officer insurance (income) loss (92 ) 15 11 Net tax credits (165 ) (126 ) (105 ) Corporate tax rate change 397 — — Other, net 23 17 (241 ) $ 3,626 $ 2,553 $ 2,433 The effective tax rates were 31.77% , 28.62% , and 26.08% , for years ended December 31, 2017 , 2016 , and 2015 , respectively. This increase in the effective tax rate resulted mostly from the Tax Cuts and Jobs Act that was signed into law on December 22, 2017. The Company's deferred tax assets and liabilities were adjusted at December 31, 2017, for the reduction of our applicable corporate income tax rate from 34% to 21%, effective January 1, 2018. This adjustment resulted in a write-down of our net deferred tax assets and an increase in our federal income tax expense of $397 thousand.

Defined Benefit Plan [Abstract]
Pension and Postretirement Benefit Plans	Postretirement Benefit Plans The Company provides certain health care and life insurance benefits for nine retired employees who have met certain eligibility requirements. All other employees retiring after reaching age 65 and having at least 15 years of service with the Company will be allowed to stay on the Company’s group life and health insurance policies, but will be required to pay premiums. The Company’s share of the estimated costs that will be paid after retirement is generally being accrued by charges to expense over the employees’ active service periods to the dates they are fully eligible for benefits. Generally Accepted Accounting Principles (“GAAP”) requires the Company to recognize the funded status (i.e. the difference between the fair value of plan assets and the projected benefit obligations) of its postretirement benefit plans in the consolidated balance sheet, with a corresponding adjustment to accumulated other comprehensive income, net of taxes. The following amounts that have not been recognized in the net periodic benefit cost of the postretirement benefit plan for the year ended December 31, 2017 but are included in other comprehensive income: unrecognized net actuarial gain of $44 thousand . The actuarial gain included in other comprehensive income and expected to be recognized in the net periodic benefit cost of the postretirement benefit plan during 2018 is $7 thousand . The following tables provide a reconciliation of the changes in the benefit obligations and fair value of assets for 2017 , 2016 , and 2015 and a statement of the funded status at December 31, 2017 , 2016 and 2015 for the postretirement benefit plans of the Company. The Company uses a December 31st measurement date for its plans.

For measurement purposes, a 8.00% annual rate of increase in the per capita cost of covered health care benefits was assumed for 2018 and 2019 , 7.00% for 2020 and 2021 , and 5.00% for 2022 and thereafter. If these rates were increased by 1.00% in each year, the benefit obligation at December 31, 2017 would have increased by $3 thousand and the net periodic benefit cost for 2017 would have increased by less than $1 thousand . If these rates were decreased by 1.00% in each year, the benefit obligation at December 31, 2017 would have decreased by $3 thousand and the net periodic benefit cost for 2017 would have decreased by less than $1 thousand . Estimated future benefit payments at December 31, 2017 , which reflect expected future service, as appropriate, were as follows: Postretirement Benefits (in thousands) 2018 $ 15 2019 14 2020 14 2021 13 2022 12 2023 - 2027 39

Share-based Compensation [Abstract]
Stock-Based Compensation	Stock-Based Compensation Restricted Stock provides grantees with rights to shares of common stock upon completion of a service period or achievement of Company performance measures. During the restriction period, all shares are considered outstanding and dividends are paid to the grantee. Outside directors are periodically granted restricted shares which vest over a period of less than nine months. During 2017 , executive officers were granted restricted shares which vest over a three year service period and restricted shares which vest based on meeting performance measures over a one year period. Vesting schedules were unchanged from the two prior years. The following table presents the activity for Restricted Stock for the years ended December 31, 2017 , 2016 and 2015 : Twelve Months Ended December 31, 2017 2016 2015 Shares Weighted Average Grant Date Fair Value Shares Weighted Average Grant Date Fair Value Shares Weighted Average Grant Date Fair Value Nonvested, beginning of period 14,901 $ 23.05 14,401 $ 22.98 15,151 $ 22.27 Granted 14,650 27.46 14,650 23.07 14,650 23.85 Vested (14,493 ) 25.90 (13,196 ) 23.00 (14,363 ) 23.09 Forfeited (657 ) 23.00 (954 ) 23.00 (1,037 ) 23.50 Nonvested, end of period 14,401 $ 24.68 14,901 $ 23.05 14,401 $ 22.98 The Company recognizes compensation expense over the vesting period based on the fair value of the Company's stock on the grant date. Compensation expense was $382 thousand , $314 thousand , and $328 thousand during December 31, 2017 , 2016 , and 2015 , respectively. The total grant date fair value of Restricted Stock which vested was $375 thousand and $303 thousand for the years ended December 31, 2017 and 2016 , respectively. Unrecognized compensation cost related to unvested Restricted Stock was $69 thousand at December 31, 2017 . This amount is expected to be recognized over a weighted average period of one year. The Company's policy is to recognize forfeitures as they occur.

Defined Contribution Plan [Abstract]
Employee Benefits	Employee Benefits The Company has established an Employee Stock Ownership Plan (ESOP) to provide additional retirement benefits to substantially all employees. Contributions can be made to the Bank of Clarke County Employee Retirement Trust to be used to purchase the Company’s common stock. There were no contributions in 2017 , 2016 , and 2015 . The Company sponsors a 401(k) savings plan under which eligible employees may defer a portion of salary on a pretax basis, subject to certain IRS limits. Prior to January 1, 2007 , the Company matched 50 percent of employee contributions, on a maximum of six percent of salary deferred, with Company common stock or cash, as elected by each employee. The shares for this purpose are provided principally by the Company’s employee stock ownership plan (ESOP), supplemented, as needed, by newly issued shares. In conjunction with amending the pension plan, the 401(k) plan was amended, effective January 1, 2007 , to include a non-elective safe-harbor employer contribution and an age-weighted employer contribution. Each December 31 st , qualifying employees will receive a non-elective safe-harbor contribution equal to three percent of their salary for that year. Also, each December 31 st , qualifying employees will receive an additional contribution based on their age and years of service. The percentage of salary for the age-weighted contribution increases on both factors, age and years of service, with a minimum of one percent of salary and a maximum of ten percent of salary. Contributions under the plan amounted to $1.0 million in 2017 , $990 thousand in 2016 , and $956 thousand in 2015 . The Company has established an Executive Supplemental Income Plan for certain key employees. Benefits are to be paid in monthly installments following retirement or death. The agreement provides that if employment is terminated for reasons other than death or disability prior to age 65 , the amount of benefits could be reduced or forfeited. The executive supplemental income benefit liability was $56 thousand and $64 thousand at December 31, 2017 and 2016 , respectively. The executive supplemental income benefit expense, based on the present value of the retirement benefits, was $29 thousand in 2017 , $29 thousand in 2016 , and $29 thousand in 2015 . The plan is unfunded; however, life insurance has been acquired on the lives of these employees in amounts sufficient to discharge the plan’s obligations.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies In the normal course of business, the Company makes various commitments and incurs certain contingent liabilities, which are not reflected in the accompanying financial statements. These commitments and contingent liabilities include various guarantees, commitments to extend credit and standby letters of credit. The Company does not anticipate any material losses as a result of these commitments. During the normal course of business, various legal claims arise from time to time which, in the opinion of management, will have no material effect on the Company’s consolidated financial statements. As a member of the Federal Reserve System, the Bank is required to maintain certain average reserve balances. These reserve balances include usable vault cash and amounts on deposit with the Federal Reserve Bank. For the final weekly reporting period in the years ended December 31, 2017 and 2016 , the amount of daily average required balances were approximately $1.5 million and $1.3 million , respectively. For both periods, these required amounts were met by vault cash and no additional amount was required to be on deposit with the Federal Reserve Bank. In addition, the Bank was required to maintain a total compensating balance on deposit with two correspondent banks in the amount of $250 thousand at December 31, 2017 and 2016 . See Note 19 with respect to financial instruments with off-balance-sheet risk.

General Discussion of Derivative Instruments and Hedging Activities [Abstract]
Derivative Instruments and Hedging Activities	Derivative Instruments and Hedging Activities Interest Rate Swaps The Company has used interest rate swaps to reduce interest rate risk and to manage interest expense. By entering into these agreements, the Company converts floating rate debt into fixed rate debt, or alternatively, converts fixed rate debt into floating rate debt. Interest differentials paid or received under the swap agreements are reflected as adjustments to interest expense. These interest rate swap agreements are derivative instruments that qualify for hedge accounting as discussed in Note 1. The notional amounts of the interest rate swaps are not exchanged and do not represent exposure to credit loss. In the event of default by a counterparty, the risk in these transactions is the cost of replacing the agreements at current market rates. On December 4, 2008 , the Company entered into an interest rate swap agreement related to the outstanding trust preferred capital notes. The swap agreement became effective on December 1, 2008 . The notional amount of the interest rate swap was $7.0 million and had an expiration date of December 1, 2016 . Under the terms of the agreement, the Company paid interest quarterly at a fixed rate of 2.85% and received interest quarterly at a variable rate of three month LIBOR. The variable rate reset on each interest payment date. This agreement was designated as a cash-flow hedge at inception of the contract until the redemption of the trust preferred capital notes on July 29, 2015. As a result of the redemption, the derivative contract was no longer classified as a cash flow hedge and was recorded in the balance sheet at its fair value with changes in fair value recorded in Other operating income in the Consolidated Statements of Income. The following tables present the effect of the derivative instrument on the Consolidated Statements of Income for December 31, 2017 , 2016 , and 2015 : Derivatives not designated as hedging instruments under GAAP Location of Gain (Loss) Amount of Gain (Loss) 2017 2016 2015 (dollars in thousands) Interest rate swap contracts, net of tax Other operating income $ — $ 149 88 The balance of the interest rate swap liability was $237 thousand at the time of the redemption of the Company's trust preferred debt on July 29, 2015. The total amount recorded in accumulated other comprehensive income at that date was reclassified to earnings due to the derecognition of the cash flow hedge. Subsequent to the redemption of the debt and reclassification, the interest rate swap derivative was adjusted to its fair value resulting in a $149 thousand and $88 thousand gain recorded in Other operating income in the Consolidated Statements of Income for the twelve months ended December 31, 2016 and 2015 , respectively.

The aggregate balance of loans to directors, principal officers and their related parties was $4.1 million and $4.7 million at December 31, 2017 and 2016 , respectively. These balances reflect total principal additions of $9.4 million and total principal payments of $10.0 million , during 2017 . The aggregate balance of deposits from directors, principal officers and their related parties was $19.4 million and $15.6 million at December 31, 2017 and 2016 , respectively.

Capital Requirements

Capital Requirements	12 Months Ended

Banking and Thrift [Abstract]
Capital Requirements	Capital Requirements The Company (on a consolidated basis) and the Bank are subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the Company’s and Bank’s financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Company and the Bank must meet specific capital guidelines that involve quantitative measures of their assets, liabilities, and certain off-balance-sheet items as calculated under regulatory accounting practices. The capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings, and other factors. Prompt corrective action provisions are not applicable to bank holding companies. In July 2013, the Federal Reserve Bank issued a final rule that makes technical changes to its market risk capital rules to align them with the BASEL III regulatory capital framework and meet certain requirements of the Dodd-Frank Act. The phase-in period for the final rules began January 1, 2015 with full compliance with the final rules to be phased in by January 1, 2019. As a part of this final rule, the Bank was required to begin calculating and disclosing Common Equity Tier 1 Capital to risk weighted assets in 2015. Although not required by the final rule, the Company also began calculating and disclosing Common Equity Tier 1 Capital to risk weighted assets in 2015. In addition to the minimum regulatory capital required for capital adequacy purposes , the Company is required to maintain a minimum Capital Conservation Buffer, in the form of common equity, in order to avoid restrictions on capital distributions and discretionary bonuses. The required amount of the Capital Conservation Buffer was 0.625% on January 1, 2016 and will increase by 0.625% each year until it reaches 2.5% on January 1, 2019. The Capital Conservation Buffer is applicable to all ratios except the leverage ratio, which is noted below as Tier 1 Capital to Average Assets. The Bank's institution specific capital conservation buffer at December 31, 2017 was 6.86%. Quantitative measures established by regulation to ensure capital adequacy require the Company and the Bank to maintain minimum amounts and ratios (set forth in the table below) of total capital, Tier 1 capital, and common equity Tier 1 capital (as defined in the regulations) to risk-weighted assets (as defined), and of Tier 1 capital to average assets (as defined). Management believes that the Company and the Bank met all capital adequacy requirements to which they are subject at December 31, 2017 and 2016 . At December 31, 2017 , the most recent notification from the Federal Reserve Bank categorized the Bank as well capitalized under the regulatory framework for prompt corrective action. To be categorized as well capitalized, an institution must maintain minimum total risk-based, Tier 1 risk-based, Tier 1 leverage, and common equity Tier 1 ratios as set forth in the following tables. There are no conditions or events since the notification that management believes have changed the Bank’s category. The following table presents the Company’s and the Bank’s actual capital amounts and ratios at December 31, 2017 and 2016 : Minimum To Be Well Minimum Capital Capitalized Under Prompt Corrective Actual Requirement Action Provisions Amount Ratio Amount Ratio Amount Ratio (dollars in thousands) December 31, 2017: Common Equity Tier 1 Capital to Risk Weighted Assets Consolidated $ 83,507 14.45 % $ 26,003 4.50 % N/A Bank of Clarke County $ 80,150 14.08 % $ 25,622 4.50 % $ 37,009 6.50 % Total Capital to Risk Weighted Assets Consolidated $ 87,959 15.22 % $ 46,228 8.00 % N/A Bank of Clarke County $ 84,583 14.86 % $ 45,550 8.00 % $ 56,938 10.00 % Tier 1 Capital to Risk Weighted Assets Consolidated $ 83,507 14.45 % $ 34,671 6.00 % N/A Bank of Clarke County $ 80,150 14.08 % $ 34,163 6.00 % $ 45,550 8.00 % Tier 1 Capital to Average Assets Consolidated $ 83,507 11.21 % $ 29,810 4.00 % N/A Bank of Clarke County $ 80,150 10.86 % $ 29,511 4.00 % $ 36,889 5.00 % December 31, 2016: Common Equity Tier 1 Capital to Risk Weighted Assets Consolidated $ 79,440 15.68 % $ 22,798 4.50 % N/A Bank of Clarke County $ 76,124 15.11 % $ 22,666 4.50 % $ 32,740 6.50 % Total Capital to Risk Weighted Assets Consolidated $ 83,977 16.58 % $ 40,531 8.00 % N/A Bank of Clarke County $ 80,640 16.01 % $ 40,295 8.00 % $ 50,369 10.00 % Tier 1 Capital to Risk Weighted Assets Consolidated $ 79,440 15.68 % $ 30,398 6.00 % N/A Bank of Clarke County $ 76,124 15.11 % $ 30,221 6.00 % $ 40,295 8.00 % Tier 1 Capital to Average Assets Consolidated $ 79,440 11.84 % $ 26,848 4.00 % N/A Bank of Clarke County $ 76,124 11.40 % $ 26,711 4.00 % $ 33,389 5.00 %

Disclosure of Restrictions on Dividends, Loans and Advances Disclosure [Abstract]
Restrictions On Dividends, Loans and Advances	Restrictions On Dividends, Loans and Advances Federal and state banking regulations place certain restrictions on dividends paid and loans or advances made by the Bank to the Company. The total amount of dividends which may be paid at any date is generally limited to the lesser of the Bank’s retained earnings or the three preceding years’ undistributed net income of the Bank. Loans or advances are limited to 10% of the Bank’s capital stock and surplus on a secured basis. In addition, dividends paid by the Bank to the Company would be prohibited if the effect thereof would cause the Bank’s capital to be reduced below applicable minimum capital requirements. At December 31, 2017 , the Bank’s retained earnings available for the payment of dividends to the Company was $5.3 million . Accordingly, $75.2 million of the Company’s equity in the net assets of the Bank was restricted at December 31, 2017 . Funds available for loans or advances by the Bank to the Company amounted to $1.1 million at December 31, 2017 .

Dividend Investment Plan [Abstract]
Dividend Investment Plan	Dividend Investment Plan The Company has a Dividend Investment Plan, which allows participants’ dividends to purchase additional shares of common stock at its fair market value on each dividend record date. During 2016, the Company amended the Plan to provide that shares of common stock purchased through the Plan would be purchased at a price equal to the market price of the shares. Prior to this date, the Plan allowed participants' dividends to purchase additional shares of common stock at 95% of its fair market value. Our board of directors determined to eliminate the discount for purchases of shares in order to reflect current best practices and market standards for dividend reinvestment plans generally and among our peers. No other changes have been made to the operation of the dividend reinvestment features of the Plan, and current participants will remain enrolled in the Plan under their current methods of participation unless they choose to alter their enrollment following the procedures described in this prospectus.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Financial Instruments with Off-Balance-Sheet Risk	Financial Instruments with Off-Balance-Sheet Risk The Company, through its subsidiary bank, is a party to credit related financial instruments with off-balance-sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit, unfunded commitments under lines of credit, and commercial and standby letters of credit. Such commitments involve, to varying degrees, elements of credit and interest rate risk in excess of the amount recognized in the consolidated balance sheets. The Company’s exposure to credit loss is represented by the contractual amount of these instruments. The Company uses the same credit policies in making commitments as it does for on-balance-sheet instruments. At December 31, 2017 and 2016 , the following financial instruments were outstanding whose contract amounts represent credit risk: 2017 2016 (dollar in thousands) Commitments to extend credit $ 3,959 $ 27,144 Unfunded commitments under lines of credit 108,483 100,530 Commercial and standby letters of credit 8,437 5,897 Commitments to extend credit are agreements to lend to a customer as long as the terms offered are acceptable and certain other conditions are met. Commitments generally have fixed expiration dates or other termination clauses. Since these commitments may expire or terminate, the total commitment amounts do not necessarily represent future cash requirements. The amount of collateral obtained, with regards to these commitments, is based on management’s credit evaluation of the customer. Unfunded commitments under lines of credit are contracts for possible future extensions of credit to existing customers. Unfunded commitments under lines of credit include, but are not limited to, home equity lines of credit, overdraft protection lines of credit, credit cards, and unsecured and secured commercial lines of credit. The terms and conditions of these commitments vary depending on the line of credit’s purpose, collateral, and maturity. The amount disclosed above represents total unused lines of credit for which a contract with the Bank has been established. Commercial and standby letters of credit are conditional commitments issued by the Bank to guarantee the performance of a customer to a third party. These letters of credit are primarily issued to support public and private borrowing arrangements. Essentially all letters of credit issued have expiration dates within one year. The credit risk involved in issuing letters of credit is essentially the same as that involved in granting loans to customers. The Bank holds collateral supporting these commitments if it is deemed necessary. At December 31, 2017 , $7.5 million of the outstanding letters of credit were collateralized. The Bank has cash accounts in other commercial banks. The amount on deposit in these banks at December 31, 2017 exceeded the insurance limits of the Federal Deposit Insurance Corporation by $1.7 million .

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements GAAP requires the Company to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures. The fair value of certain assets and liabilities is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. “Fair Value Measurements” defines fair value, establishes a framework for measuring fair value, establishes a three-level valuation hierarchy for disclosure of fair value measurement and enhances disclosure requirements for fair value measurements. The valuation hierarchy is based upon the transparency of inputs to the valuation of an asset or liability as of the measurement date. The three levels are defined as follows: • Level 1 Inputs to the valuation methodology are quoted prices (unadjusted) for identical assets or liabilities in active markets. • Level 2 Inputs to the valuation methodology include quoted prices for similar assets and liabilities in active markets, and inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument. • Level 3 Inputs to the valuation methodology are unobservable and significant to the fair value measurement. The following sections provide a description of the valuation methodologies used for instruments measured at fair value, as well as the general classification of such instruments pursuant to the valuation hierarchy: Securities Available for Sale: Where quoted prices are available in an active market, securities are classified within Level 1 of the valuation hierarchy. Level 1 securities would include highly liquid government bonds, mortgage products and exchange traded equities. If quoted market prices are not available, then fair values are estimated by using pricing models, quoted prices of securities with similar characteristics, or discounted cash flow. Level 2 securities would include U.S. agency securities, mortgage-backed agency securities, obligations of states and political subdivisions and certain corporate, asset backed and other securities. In certain cases where there is limited activity or less transparency around inputs to the valuation, securities are classified within Level 3 of the valuation hierarchy. The following table presents balances of financial assets and liabilities measured at fair value on a recurring basis at December 31, 2017 and December 31, 2016 : Fair Value Measurements at December 31, 2017 Using Balance as of Quoted Prices Significant Significant December 31, 2017 (Level 1) (Level 2) (Level 3) (in thousands) Assets: Securities available for sale Obligations of U.S. government corporations and agencies $ 21,520 $ — $ 21,520 $ — Mortgage-backed securities 61,244 — 61,244 — Obligations of states and political subdivisions 49,802 — 49,259 543 Total assets at fair value $ 132,566 $ — $ 132,023 $ 543 Liabilities: Total liabilities at fair value $ — $ — $ — $ — Fair Value Measurements at December 31, 2016 Using Balance as of Quoted Prices Significant Significant December 31, 2016 (Level 1) (Level 2) (Level 3) (in thousands) Assets: Securities available for sale Obligations of U.S. government corporations and agencies $ 30,441 $ — $ 30,441 $ — Mortgage-backed securities 42,372 — 42,372 — Obligations of states and political subdivisions 46,449 — 45,835 614 Total assets at fair value $ 119,262 $ — $ 118,648 $ 614 Liabilities: Total liabilities at fair value $ — $ — $ — $ — The table below presents a reconciliation for all assets measured and recognized at fair value on a recurring basis using significant unobservable inputs (Level 3) for the twelve months ended December 31, 2017 and 2016 . Level 3 Recurring Fair Value Measurements As of and for the Year Ended December 31, 2017 December 31, 2016 (in thousands) Beginning balance $ 614 $ 684 Purchases — — Sales — — Issuances — — Settlements (71 ) (70 ) Total assets at fair value $ 543 $ 614 Certain financial assets are measured at fair value on a nonrecurring basis in accordance with GAAP. Adjustments to the fair value of these assets usually result from the application of lower of cost or market accounting or write downs of individual assets. The following describes the valuation techniques used by the Company to measure certain financial and nonfinancial assets recorded at fair value on a nonrecurring basis in the financial statements: Impaired Loans: Loans are designated as impaired when, in the judgment of management based on current information and events, it is probable that all amounts due according to the contractual terms of the loan agreement will not be collected when due. The measurement of loss associated with impaired loans can be based on the present value of its expected future cash flows discounted at the loan's coupon rate, or at the loans' observable market price or the fair value of the collateral securing the loans, if they are collateral dependent. Collateral may be in the form of real estate or business assets including equipment, inventory, and accounts receivable. The vast majority of the collateral is real estate. The value of real estate collateral is determined utilizing a market valuation approach based on an appraisal conducted by an independent, licensed appraiser using observable market data within the last twelve months (Level 2). However, if the collateral is a house or building in the process of construction or if an appraisal of the property is more than one year old and not solely based on observable market comparables or management determines the fair value of the collateral is further impaired below the appraised value, then a Level 3 valuation is considered to measure the fair value. The value of business equipment is based upon an outside appraisal, of one year or less, if deemed significant, or the net book value on the applicable business’s financial statements if not considered significant using observable market data. Likewise, values for inventory and accounts receivables collateral are based on financial statement balances or aging reports (Level 3). Impaired loans allocated to the allowance for loan losses are measured at fair value on a nonrecurring basis. Any fair value adjustments are recorded in the period incurred as provision for loan losses on the Consolidated Statements of Income. Other Real Estate Owned: Assets acquired through, or in lieu of, loan foreclosure are held for sale and are initially recorded at the fair value of the property, less estimated selling costs, establishing a new costs basis. Any write-downs based on the asset’s fair value at the date of acquisition are charged to the allowance for loan losses. Costs of significant property improvements are capitalized, whereas costs relating to holding property are expensed. The portion of interest costs relating to development of real estate is capitalized. Valuations are periodically obtained by management, and any subsequent write-downs are recorded as a charge to operations, if necessary, to reduce the carrying value of a property to the lower of its cost or fair value less cost to sell. The fair value measurement of real estate held in other real estate owned is assessed in the same manner as impaired loans described above. We believe that the fair value component in its valuation follows the provisions of GAAP. The following table displays quantitative information about Level 3 Fair Value Measurements for certain financial assets measured at fair value on a nonrecurring basis for December 31, 2017 and December 31, 2016 : Quantitative information about Level 3 Fair Value Measurements for December 31, 2017 Valuation Technique(s) Unobservable Input Range Weighted Average Assets: Impaired loans Discounted appraised value Selling cost 6% - 12% 7% Impaired loans Present value of cash flows Discount rate 4% - 10% 5% Other real estate owned Discounted appraised value Selling cost 6% 6% Quantitative information about Level 3 Fair Value Measurements for December 31, 2016 Valuation Technique(s) Unobservable Input Range Weighted Average Assets: Impaired loans Discounted appraised value Selling cost 12% 12% Impaired loans Present value of cash flows Discount rate 4% - 7% 5% Other real estate owned Discounted appraised value Selling cost 6% 6% The following table summarizes the Company’s financial and nonfinancial assets that were measured at fair value on a nonrecurring basis at December 31, 2017 and December 31, 2016 : Carrying value at December 31, 2017 Balance as of Identical Assets Observable Inputs Unobservable Inputs December 31, 2017 (Level 1) (Level 2) (Level 3) (in thousands) Financial Assets: Impaired loans $ 2,248 $ — $ — $ 2,248 Nonfinancial Assets: Other real estate owned 106 — — 106 Carrying value at December 31, 2016 Balance as of Quoted Prices in Active Markets for Identical Assets Significant Other Observable Inputs Significant Unobservable Inputs December 31, 2016 (Level 1) (Level 2) (Level 3) (in thousands) Financial Assets: Impaired loans $ 2,671 $ — $ — $ 2,671 Nonfinancial Assets: Other real estate owned 370 — — 370 The fair value of a financial instrument is the current amount that would be exchanged between willing parties, other than in a forced liquidation. Fair value is best determined based upon quoted market prices. However, in many instances, there are no quoted market prices for the Company’s various financial instruments. In cases where quoted market prices are not available, fair values are based on estimates using present value or other valuation techniques. Those techniques are significantly affected by the assumptions used, including the discount rate and estimates of future cash flows. Accordingly, the fair value estimates may not be realized in an immediate settlement of the instrument. The aggregate fair value amounts presented may not necessarily represent the underlying fair value of the Company. The following methods and assumptions were used to estimate the fair value of the Company’s financial instruments: Cash and short-term investments/restricted investments/accrued interest: The fair value was equal to the carrying amount. Securities: The fair value, excluding restricted securities, was based on quoted market prices. The fair value of restricted securities approximated the carrying amount based on the redemption provisions of the issuers. Loans: The fair value of variable rate loans, which reprice frequently and with no significant change in credit risk, was equal to the carrying amount. The fair value of all other loans was determined using discounted cash flow analysis. The discount rate was equal to the current interest rate on similar products. Bank owned life insurance: The carrying amount of bank owned life insurance was a reasonable estimate of fair value. Deposits and borrowings: The fair value of demand deposits, savings accounts, and certain money market deposits was equal to the carrying amount. The fair value of all other deposits and borrowings was determined using discounted cash flow analysis. The discount rate was equal to the current interest rate on similar products. Off-balance-sheet financial instruments: The fair value of commitments to extend credit was estimated using the fees currently charged to enter similar agreements, taking into account the remaining terms of the agreements and the credit worthiness of the counterparties. The fair value of fixed rate loan commitments also considered the difference between current interest rates and the committed interest rates. The fair value of standby letters of credit was estimated using the fees currently charged for similar agreements or on the estimated cost to terminate or otherwise settle the obligations with the counterparties. The carrying amount and fair value of the Company’s financial instruments at December 31, 2017 and 2016 were as follows: Fair Value Measurements at December 31, 2017 Using Carrying Value as of Quoted Prices Significant Significant Fair Value as of December 31, 2017 (Level 1) (Level 2) (Level 3) December 31, 2017 (in thousands) Financial Assets: Cash and short-term investments $ 35,848 $ 35,848 $ — $ — $ 35,848 Securities 132,566 — 132,023 543 132,566 Restricted Investments 1,107 — 1,107 — 1,107 Loans, net 564,406 — — 559,665 559,665 Bank owned life insurance 486 — 486 — 486 Accrued interest receivable 1,955 — 1,955 — 1,955 Financial Liabilities: Deposits $ 663,414 $ — $ 662,696 $ — $ 662,696 Accrued interest payable 44 — 44 — 44 Fair Value Measurements at December 31, 2016 Using Carrying Value Quoted Prices Significant Significant Fair Value as of December 31, 2016 (Level 1) (Level 2) (Level 3) December 31, 2016 (in thousands) Financial assets: Cash and short-term investments $ 35,281 $ 35,281 $ — $ — $ 35,281 Securities 119,262 — 118,648 614 119,262 Restricted Investments 1,068 — 1,068 — 1,068 Loans, net 512,437 — — 512,181 512,181 Bank owned life insurance 1,769 — 1,769 — 1,769 Accrued interest receivable 588 — 588 — 588 Financial liabilities: Deposits $ 603,877 $ — $ 603,516 $ — $ 603,516 Accrued interest payable 34 — 34 — 34 The Company assumes interest rate risk (the risk that general interest rate levels will change) during its normal operations. As a result, the fair value of the Company’s financial instruments will change when interest rate levels change and that change may be either favorable or unfavorable to the Company. Management attempts to match maturities of assets and liabilities in order to minimize interest rate risk. However, borrowers with fixed rate obligations are less likely to prepay their principal balance in a rising rate environment and more likely to do so in a falling rate environment. Conversely, depositors who are receiving fixed rate interest payments 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 the terms of new loans and deposits and by investing in securities with terms that mitigate the Company’s overall interest rate risk.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Principles of Consolidation	Principles of Consolidation The Company owns 100% of Bank of Clarke County (the “Bank”). The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiary. All significant intercompany accounts and transactions between the Company and the Bank have been eliminated.
Trust Assets	Trust Assets Eagle Investment Group (“EIG”), as a division of the Bank offers both a trust department and investment services. The trust services division of EIG offers a full range of personal and retirement plan services, which include serving as agent for bill paying and custody of assets, as investment manager with full authority or advisor, as trustee or co-trustee for trusts under will or under agreement, as trustee of life insurance trusts, as guardian or committee, as agent under a power of attorney, as executor or co-executor for estates, as custodian or investment advisor for individual retirement plans, and as trustee or trust advisor for corporate retirement plans such as profit sharing and 401(k) plans. The brokerage division of EIG offers a full range of investment services, which include tax-deferred annuities, IRAs and rollovers, mutual funds, retirement plans, 529 college savings plans, life insurance, long term care insurance, fixed income investing, brokerage CDs, and full service or discount brokerage services. Securities and other property held by the Eagle Investment Group in a fiduciary or agency capacity are not assets of the Company and are not included in the accompanying consolidated financial statements.
Cash and Cash Equivalents	Cash and Cash Equivalents For purposes of reporting cash flows, cash and cash equivalents include cash on hand, amounts due from banks, federal funds sold, and interest bearing deposits. Generally, federal funds are purchased and sold for one-day periods.
Securities	Securities Debt securities that management has the positive intent and ability to hold to maturity are classified as “held to maturity” and recorded at amortized cost. Securities not classified as held to maturity, including equity securities with readily determinable fair values, are classified as “available for sale” and recorded at fair value, with unrealized gains and losses excluded from earnings and reported in other comprehensive income. Purchase premiums and discounts are recognized in interest income using the interest method over the terms of the securities. Declines in the fair value of held to maturity and available for sale securities below their cost that are deemed to be “other than temporary” are reflected in earnings as realized losses. In estimating “other than temporary” impairment losses, management considers (1) the length of time and the extent to which the fair value has been less than cost, (2) the financial condition and near-term prospects of the issuer, and (3) the intent and ability of the Company to retain its investment in the issuer for a period of time sufficient to allow for any anticipated recovery of fair value. Gains and losses on the sale of securities are recorded on the trade date and are determined using the specific identification method. The Bank is required to maintain an investment in the capital stock of certain correspondent banks. No readily available market exists for this stock and it has no quoted market value. The investment in these securities is recorded at cost and they are reported on the Company’s consolidated balance sheet as restricted investments.
Loans	Loans The Company grants mortgage, commercial and consumer loans to customers. A substantial portion of the loan portfolio is represented by mortgage loans throughout the Counties of Clarke, Frederick, and Loudoun, Virginia and the City of Winchester, Virginia. The ability of the Company’s debtors to honor their contracts is dependent upon the real estate and general economic conditions in this area. Loans that management has the intent and ability to hold for the foreseeable future or until maturity or pay-off generally are reported at their outstanding unpaid principal balances adjusted for the allowance for loan losses. Interest income is accrued on the unpaid principal balance. Loan fees collected and certain costs incurred related to loan originations are deferred and amortized as an adjustment to interest income over the life of the related loans. Deferred fees and costs are recorded as an adjustment to interest income using a method that approximates a constant yield. The accrual of interest on mortgage and commercial loans is discontinued at the time the loan is 120 and 90 days delinquent, respectively, unless the credit is well-secured and in process of collection. Credit card loans and other personal loans are typically charged off no later than 180 days past due. Past due status is based on the contractual terms of the loan. In all cases, loans are placed on nonaccrual or charged-off at an earlier date if collection of principal and interest is considered doubtful. All interest accrued but not collected for loans that are placed on nonaccrual or charged off is reversed against interest income. The interest on these loans is accounted for on the cash-basis or cost-recovery method, until qualifying for return to accrual. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured.
Troubled Debt Restructurings (TDR)	Troubled Debt Restructurings (TDR) In situations where, for economic or legal reasons related to a borrower’s financial condition, management may grant a concession to the borrower that it would not otherwise consider, the related loan is classified as a TDR. TDRs are considered impaired loans. Upon designation as a TDR, the Company evaluates the borrower’s payment history, past due status and ability to make payments based on the revised terms of the loan. If a loan was accruing prior to being modified as a TDR and if the Company concludes that the borrower is able to make such payments, and there are no other factors or circumstances that would cause it to conclude otherwise, the loan will remain on an accruing status. If a loan was on non-accrual status at the time of the TDR, the loan will remain on non-accrual status following the modification and may be returned to accrual status based on the policy for returning loans to accrual status as noted above.
Risks by Loan Portfolio Segments	Risks by Loan Portfolio Segments One-to-Four-Family Residential Real Estate Lending Residential mortgage loans generally are made on the basis of the borrower’s ability to make repayment from employment and other income and are secured by real estate whose value tends to be readily ascertainable. As part of the application process, information is gathered concerning income, employment and credit history of the applicant. The valuation of residential collateral is provided by independent fee appraisers who have been approved by the Bank’s Directors Loan Committee. Commercial Real Estate Lending Commercial real estate lending entails significant additional risk as compared with residential mortgage lending. Commercial real estate loans typically involve larger loan balances concentrated with single borrowers or groups of related borrowers. Additionally, the repayment of loans secured by income producing properties is typically dependent on the successful operation of a business or a real estate project and thus may be subject, to a greater extent, to adverse conditions in the real estate market or the economy, in general. Construction and Land Development Lending There are two characteristics of construction lending which impact its overall risk as compared to residential mortgage lending. First, there is more concentration risk due to the extension of a large loan balance through several lines of credit to a single developer or contractor. Second, there is more collateral risk due to the fact that loan funds are provided to the borrower based upon the estimated value of the collateral after completion. This could cause an inaccurate estimate of the amount needed to complete construction or an excessive loan-to-value ratio. To mitigate the risks associated with construction lending, the Bank generally limits loan amounts to 80% of the estimated appraised value of the finished home. Commercial and Industrial Lending Commercial business loans generally have more risk than residential mortgage loans, but have higher yields. To manage these risks, the Bank generally obtains appropriate collateral and personal guarantees from the borrower’s principal owners and monitors the financial condition of the borrower. Commercial business loans typically are made on the basis of the borrower’s ability to make repayment from cash flow from its business and are secured by business assets, such as commercial real estate, accounts receivable, equipment and inventory. As a result, the availability of funds for the repayment of commercial business loans is substantially dependent on the success of the business itself. Furthermore, the collateral for commercial business loans may depreciate over time and generally cannot be appraised with as much precision as residential real estate. Consumer Lending Consumer loans generally entail greater risk than residential mortgage loans, particularly in the case of consumer loans which are unsecured or secured by rapidly depreciable assets such as automobiles. In such cases, any repossessed collateral on a defaulted consumer loan may not provide an adequate source of repayment of the outstanding loan balance as a result of the greater likelihood of damage, loss or depreciation.
Allowance For Loan Losses	Allowance for Loan Losses The allowance for loan losses is established as losses are estimated to have occurred through a provision for (recovery of) loan losses charged to earnings. Loan losses are charged against the allowance when management believes the uncollectability of a loan balance is confirmed. Subsequent recoveries, if any, are credited to the allowance. The allowance for loan losses is evaluated on a regular basis by management and is based upon management’s periodic review of the collectability of the loans in light of historical experience, the nature and volume of the loan portfolio, adverse situations that may affect the borrower’s ability to repay, estimated value of any underlying collateral and prevailing economic conditions. This evaluation is inherently subjective as it requires estimates that are susceptible to significant revision as more information becomes available. The allowance consists of specific, general and unallocated components. The specific component relates to loans that are impaired. An allowance is established when the discounted cash flows (or collateral value or observable market price) of the impaired loan is lower than the carrying value of that loan. The general component covers non-impaired loans and is based on historical loss experience and other qualitative factors. Other qualitative factors considered in the general component include the levels and trends in delinquencies and nonperforming loans, trends in volume and terms of loans, the effects of any changes in lending policies, the experience, ability, and depth of management, national and local economic trends and conditions, concentrations of credit, the quality of the Company’s loan review system, competition and regulatory requirements. An unallocated component is maintained to cover uncertainties that could affect management’s estimate of probable losses. The unallocated component of the allowance reflects the margin of imprecision inherent in the underlying assumptions used in the methodologies for estimating specific and general losses in the portfolio. A loan is considered impaired when, based on current information and events, it is probable that the Company will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement. Factors considered by management in determining impairment include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record, and the amount of the shortfall in relation to the principal and interest owed. Impairment is measured on a loan-by-loan basis for commercial and construction loans by either the present value of expected future cash flows discounted at the loan’s effective interest rate, the loan’s obtainable market price, or the fair market value less estimated liquidation costs of the collateral if the loan is collateral dependent. Large groups of smaller balance homogeneous loans are collectively evaluated for impairment. Accordingly, the Company does not separately identify individual consumer and residential loans for impairment disclosures, unless such loans are the subject of a restructuring agreement.
Bank Premises and Equipment	Bank Premises and Equipment Land is carried at cost. Buildings and equipment are carried at cost, less accumulated depreciation computed on the straight-line method over the estimated useful lives of the assets. Estimated useful lives range from 10 to 39 years for buildings and 3 to 10 years for furniture and equipment.
Other Real Estate Owned	Other Real Estate Owned Assets acquired through, or in lieu of, loan foreclosure are held for sale and are initially recorded at the fair value of the property, less estimated selling costs at the date of foreclosure. Any write-downs based on the asset’s fair value at the date of acquisition are charged to the allowance for loan losses. After foreclosure, valuations are periodically performed by management and property held for sale is carried at the lower of the new cost basis or fair value less estimated cost to sell. Impairment losses on property to be held and used are measured as the amount by which the carrying amount of a property exceeds its fair value. Costs of significant property improvements are capitalized, whereas costs relating to holding property are expensed. The portion of interest costs relating to development of real estate is capitalized. Valuations are periodically performed by management, and any subsequent write-downs are recorded as a charge to operations, if necessary, to reduce the carrying value of a property to the lower of its cost or fair value less cost to sell. Revenue and expenses from operations and changes in the valuation allowance are included in the net expenses from foreclosed assets.
Retirement Plans	Retirement Plans The Company sponsors a 401(k) savings plan under which eligible employees may defer a portion of their compensation on a pretax basis. The Company also provides a match to participants in this plan, as described more fully in Note 12.
Stock-Based Compensation Plan	Stock-Based Compensation Plan During 2014, the Company’s shareholders approved a stock incentive plan which allows key employees and directors to increase their personal financial interest in the Company. This plan permits the issuance of incentive stock options and non-qualified stock options and the award of stock appreciation rights, common stock, restricted stock, and phantom stock. The plan, as adopted, authorized the issuance of up to 500,000 shares of common stock. This plan is discussed more fully in Note 11.
Income Taxes	Income Taxes Deferred income tax assets and liabilities are determined using the liability (or balance sheet) method. Under this method, the net deferred tax asset or liability is determined based on the tax effects of the temporary differences between the book and tax bases of the various assets and liabilities and gives current recognition to changes in tax rates and laws. When tax returns are filed, it is likely that some positions taken would be sustained upon examination by the applicable taxing authority, while others are subject to uncertainty about the merits of the position taken or the amount of the position that would be ultimately sustained. The benefit of a tax position is recognized in the financial statements in the period during which, based on all available evidence, the Company believes it is “more likely than not” that the position will be sustained upon examination, including the resolution of appeals or litigation processes, if any. Tax positions taken are not offset or aggregated with other positions. Tax positions that meet the “more likely than not” recognition threshold are measured as the largest amount of tax benefit that is more than fifty percent ( 50% ) likely of being realized upon settlement with the applicable taxing authority. The portion of the benefits associated with tax positions taken that exceeds the amount measured as described above is reflected as a liability for unrecognized tax benefits in the balance sheet along with any associated interest and penalties that would be payable to the applicable taxing authority upon examination. Interest and penalties associated with unrecognized tax benefits are classified as additional income taxes in the statement of income. The Company has no uncertain tax positions.
Advertising	Advertising The Company follows the policy of charging the costs of advertising to expense as incurred.
Reclassifications	Reclassifications Certain reclassifications have been made to the 2016 financial statements to conform to reporting for 2017 . The results of the reclassifications are not considered material and had no effect on prior years' net income or shareholders' equity.
Earnings Per Common Share	Earnings Per Common Share Basic earnings per share represents income available to common shareholders divided by the weighted average number of common shares outstanding during the period. Nonvested restricted shares are included in the weighted average number of common shares used to compute basic earnings per share because of dividend participation and voting rights. Diluted earnings per share reflects additional common shares that would have been outstanding if dilutive potential common shares had been issued, as well as any adjustment to income that would result from the assumed issuance. The number of potential common shares is determined using the treasury method
Comprehensive Income	Comprehensive Income Accounting principles generally accepted in the United States of America require that recognized revenue, expenses, gains and losses be included in net income. Certain changes in assets and liabilities, net of income taxes, are reported within the balance sheet as a separate component of shareholders’ equity. These changes, along with net income, are components of comprehensive income and are reported in the statement of comprehensive income. In addition to net income, the Company’s comprehensive income includes changes in the benefit obligations and plan assets for postretirement benefit plans, unrealized gains or losses on interest rate swaps, and unrealized gains or losses on available for sale securities.
Derivative Financial Instruments	Derivative Financial Instruments The Company follows GAAP to account for derivative and hedging activities. Accordingly, a derivative is recognized in the balance sheet at its fair value. The fair value of a derivative is determined by quoted market prices and mathematical models using current and historical data. If certain hedging criteria are met, including testing for hedge effectiveness, special hedge accounting may be applied. The Company assesses each hedge, both at inception and on an ongoing basis, to determine whether the derivative used in a hedging transaction is effective in offsetting changes in the fair value or cash flows of the hedged item and whether the derivative is expected to remain effective during subsequent periods. The Company discontinues hedge accounting when (a) it determines that a derivative is no longer effective in offsetting changes in fair value or cash flows of a hedged item; (b) the derivative expires or is sold, terminated or exercised; (c) probability exists that the forecasted transaction will no longer occur or (d) management determines that designating the derivative as a hedging instrument is no longer appropriate. When hedge accounting is discontinued and a derivative remains outstanding, the Company recognizes the derivative in the balance sheet at its fair value and changes in the fair value are recognized in net income. At inception, the Company designates a derivative as (a) a fair value hedge of recognized assets or liabilities or of unrecognized firm commitments (fair-value hedge) or (b) a hedge of forecasted transactions or variable cash flows to be received or paid in conjunction with recognized assets or liabilities (cash-flow hedge). For a derivative treated as a fair-value hedge, a change in fair value is recorded as an adjustment to the hedged item and recognized in net income. For a derivative treated as a cash flow hedge, the effective portion of a change in fair value is recorded as an adjustment to the hedged item and recognized as a component of accumulated other comprehensive income (loss) within shareholders’ equity. For a derivative treated as a cash flow hedge, the ineffective portion of a change in fair value is recorded as an adjustment to the hedged item and recognized in net income. For more information on derivative financial instruments see Note 14 to the Consolidated Financial Statements.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for loan losses, valuation of other real estate owned, and the evaluation for other-than-temporary impairment of investment securities.
Stock Repurchase Program	Stock Repurchase Program On June 21, 2017 , the Corporation renewed the stock repurchase program to repurchase up to 150,000 shares of its common stock prior to June 30, 2018 . During 2017 , the Company purchased 52,936 shares of its Common Stock under its stock repurchase program at an average price of $29.54 . During 2016 , the Company purchased 89,607 shares of its Common Stock under its stock repurchase program at an average price of $23.92 . All of these shares we retired. There was no repurchase activity during 2015 . The maximum number of shares that may yet be purchased under the plan as of December 31, 2017 are 111,115 .
Recent Accounting Pronouncements	Recent Accounting Pronouncements In May 2014, the FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers: Topic 606.” This ASU revised guidance for the recognition, measurement, and disclosure of revenue from contracts with customers. The original guidance has been amended through subsequent accounting standard updates that resulted in technical corrections, improvements, and a one-year deferral of the effective date to January 1, 2018. The guidance, as amended, is applicable to all entities and, once effective, will replace significant portions of existing industry and transaction-specific revenue recognition rules with a more principles-based recognition model. Most revenue associated with financial instruments, including interest income, loan origination fees, and credit card fees, is outside the scope of the guidance. Gains and losses on investment securities, derivatives, and sales of financial instruments are similarly excluded from the scope. Entities can elect to adopt the guidance either on a full or modified retrospective basis. Full retrospective adoption will require a cumulative effect adjustment to retained earnings as of the beginning of the earliest comparative period presented. Modified retrospective adoption will require a cumulative effect adjustment to retained earnings as of the beginning of the reporting period in which the entity first applies the new guidance. The Company plans to adopt this guidance on the effective date, January 1, 2018 via the modified retrospective approach. The Company has completed its assessment of the adoption of this ASU, noting the standard will result in expanded disclosures related to non-interest income and enhance the qualitative disclosures on the revenues within the scope of the new guidance. The Company has concluded the adoption of ASU 2014-09 will not have a material impact on its consolidated financial statements. In January 2016, the FASB issued ASU 2016-01, “Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities.” The amendments in ASU 2016-01, among other things: 1) Requires equity investments (except those accounted for under the equity method of accounting, or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income. 2) Requires public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes. 3) Requires separate presentation of financial assets and financial liabilities by measurement category and form of financial asset (i.e., securities or loans and receivables). 4) Eliminates the requirement for public business entities to disclose the method(s) and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost. The amendments in this ASU are effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. This ASU has been discussed with the Company's current vendor to address updated disclosure requirements of 2016-01. The Company does not expect the adoption of ASU 2016-01 to have a material impact on its consolidated financial statements. In February 2016, the FASB issued ASU No. 2016-02, “Leases (Topic 842).” Among other things, in the amendments in ASU 2016-02, lessees will be required to recognize the following for all leases (with the exception of short-term leases) at the commencement date: (1) A lease liability, which is a lessee‘s obligation to make lease payments arising from a lease, measured on a discounted basis; and (2) A right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. Under the new guidance, lessor accounting is largely unchanged. Certain targeted improvements were made to align, where necessary, lessor accounting with the lessee accounting model and Topic 606, Revenue from Contracts with Customers. The amendments in this ASU are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early application is permitted upon issuance. Lessees (for capital and operating leases) and lessors (for sales-type, direct financing, and operating leases) must apply a modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. The modified retrospective approach would not require any transition accounting for leases that expired before the earliest comparative period presented. Lessees and lessors may not apply a full retrospective transition approach. The Company is currently assessing the impact that ASU 2016-02 will have on its consolidated financial statements. The Company has been gathering the lease agreement data and has begun to analyze the monetary impact to the consolidated financial statements. At December 31, 2017, the Company had only one lease. In June 2016, the FASB issued ASU No. 2016-13, “Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments.” The amendments in this ASU, among other things, require the measurement of all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. Financial institutions and other organizations will now use forward-looking information to better inform their credit loss estimates. Many of the loss estimation techniques applied today will still be permitted, although the inputs to those techniques will change to reflect the full amount of expected credit losses. In addition, the ASU amends the accounting for credit losses on available-for-sale debt securities and purchased financial assets with credit deterioration. The amendments in this ASU are effective for SEC filers for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. The Company is currently assessing the impact that ASU 2016-13 will have on its consolidated financial statements. The Company formed a CECL committee during 2016 which continues to meet monthly to address the compliance requirements. Historic loan data is currently being gathered and reviewed for completeness and accuracy. In addition, the committee is in the process of selecting a model that will assist in calculating the financial impact of ASU 2016-13 and anticipates running parallel allowance models under the current and new standard well in advance of the required implementation date. In August 2016, the FASB issued ASU No. 2016-15, “Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments”, to address diversity in how certain cash receipts and cash payments are presented and classified in the statement of cash flows. The amendments are effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. The amendments should be applied using a retrospective transition method to each period presented. If retrospective application is impractical for some of the issues addressed by the update, the amendments for those issues would be applied prospectively as of the earliest date practicable. Early adoption is permitted, including adoption in an interim period. The Company does not expect the adoption of ASU 2016-15 to have a material impact on its consolidated financial statements. In January 2017, the FASB issued ASU No. 2017-01, “Business Combinations (Topic 805): Clarifying the Definition of a Business”. The amendments in this ASU clarify the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. Under the current implementation guidance in Topic 805, there are three elements of a business-inputs, processes, and outputs. While an integrated set of assets and activities (collectively referred to as a “set”) that is a business usually has outputs, outputs are not required to be present. In addition, all the inputs and processes that a seller uses in operating a set are not required if market participants can acquire the set and continue to produce outputs. The amendments in this ASU provide a screen to determine when a set is not a business. If the screen is not met, the amendments (1) require that to be considered a business, a set must include, at a minimum, an input and a substantive process that together significantly contribute to the ability to create output and (2) remove the evaluation of whether a market participant could replace missing elements. The ASU provides a framework to assist entities in evaluating whether both an input and a substantive process are present. The amendments in this ASU are effective for annual periods beginning after December 15, 2017, including interim periods within those annual periods. The amendments in this ASU should be applied prospectively on or after the effective date. No disclosures are required at transition. The Company does not expect the adoption of ASU 2017-01 to have a material impact on its consolidated financial statements. In January 2017, the FASB issued ASU No. 2017-04, “Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment”. The amendments in this ASU simplify how an entity is required to test goodwill for impairment by eliminating Step 2 from the goodwill impairment test. Step 2 measures a goodwill impairment loss by comparing the implied fair value of a reporting unit’s goodwill with the carrying amount of that goodwill. Instead, under the amendments in this ASU, an entity should perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity still has the option to perform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary. Public business entities that are U.S. Securities and Exchange Commission (SEC) filers should adopt the amendments in this ASU for annual or interim goodwill impairment tests in fiscal years beginning after December 15, 2019. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The Company does not expect the adoption of ASU 2017-04 to have a material impact on its consolidated financial statements. In March 2017, the FASB issued ASU 2017-07, “Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost.” The amendments in this ASU require an employer that offers defined benefit pension plans, other postretirement benefit plans, or other types of benefits accounted for under Topic 715 to report the service cost component of net periodic benefit cost in the same line item(s) as other compensation costs arising from services rendered during the period. The other components of net periodic benefit cost are required to be presented in the income statement separately from the service cost component. If the other components of net periodic benefit cost are not presented on a separate line or lines, the line item(s) used in the income statement must be disclosed. In addition, only the service cost component will be eligible for capitalization as part of an asset, when applicable. The amendments are effective for annual periods beginning after December 15, 2017, including interim periods within those annual periods. Early adoption is permitted. The Company does not expect the adoption of ASU 2017-07 to have a material impact on its consolidated financial statements. In March 2017, the FASB issued ASU 2017‐08, “Receivables-Nonrefundable Fees and Other Costs (Subtopic 310‐20), Premium Amortization on Purchased Callable Debt Securities.” The amendments in this ASU shorten the amortization period for certain callable debt securities purchased at a premium. Upon adoption of the standard, premiums on these qualifying callable debt securities will be amortized to the earliest call date. Discounts on purchased debt securities will continue to be accreted to maturity. The amendments are effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Early adoption is permitted, including adoption in an interim period. Upon transition, entities should apply the guidance on a modified retrospective basis, with a cumulative-effect adjustment to retained earnings as of the beginning of the period of adoption and provide the disclosures required for a change in accounting principle. The Company is currently assessing the impact that ASU 2017‐08 will have on its consolidated financial statements. During May 2017, the FASB issued ASU 2017‐09, “Compensation - Stock Compensation (Topic 718): Scope of Modification Accounting.” The amendments provide guidance on determining which changes to the terms and conditions of share-based payment awards require an entity to apply modification accounting under Topic 718. The amendments are effective for annual periods, including interim periods within those annual periods, beginning after December 15, 2017. Early adoption is permitted, including adoption in any interim period, for reporting periods for which financial statements have not yet been issued. The Company is currently assessing the impact that ASU 2017‐09 will have on its consolidated)financial statements. In August 2017, the FASB issued ASU 2017-12, “Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities.” The amendments in this ASU modify the designation and measurement guidance for hedge accounting as well as provide for increased transparency regarding the presentation of economic results on both the financial statements and related footnotes. Certain aspects of hedge effectiveness assessments will also be simplified upon implementation of this update. The amendments are effective for annual periods, including interim periods within those annual periods, beginning after December 15, 2018. Early adoption is permitted, including adoption in any interim period. The Company does not expect the adoption of ASU 2017-12 to have a material impact on its consolidated financial statements. In February 2018, the FASB issued ASU 2018-02, “Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income.” The amendments provide financial statement preparers with an option to reclassify stranded tax effects within accumulated other comprehensive income to retained earnings in each period in which the effect of the change in the U.S. federal corporate income tax rate in the Tax Cuts and Jobs Act (or portion thereof) is recorded. The amendments are effective for all organizations for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Early adoption is permitted. Organizations should apply the proposed amendments either in the period of adoption or retrospectively to each period (or periods) in which the effect of the change in the U.S. federal corporate income tax rate in the Tax Cuts and Jobs Act is recognized. The Company has elected to reclassify the stranded income tax effects from the Tax Cuts and Jobs Act in the consolidated financial statements for the period ending December 31, 2017. The amount of this reclassification in 2017 was $51 thousand.

Loans and Leases Receivable, Troubled Debt Restructuring Policy [Policy Text Block]	Troubled Debt Restructurings (TDR) In situations where, for economic or legal reasons related to a borrower’s financial condition, management may grant a concession to the borrower that it would not otherwise consider, the related loan is classified as a TDR. TDRs are considered impaired loans. Upon designation as a TDR, the Company evaluates the borrower’s payment history, past due status and ability to make payments based on the revised terms of the loan. If a loan was accruing prior to being modified as a TDR and if the Company concludes that the borrower is able to make such payments, and there are no other factors or circumstances that would cause it to conclude otherwise, the loan will remain on an accruing status. If a loan was on non-accrual status at the time of the TDR, the loan will remain on non-accrual status following the modification and may be returned to accrual status based on the policy for returning loans to accrual status as noted above.
