Organization And Summary Of Significant Accounting Policies [Abstract]
Organization And Summary Of Significant Accounting Policies	1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES  Organization and General  Evans Bancorp, Inc. (the “Company”) was organized as a New York business corporation and incorporated under the laws of the State of New York on October 28, 1988 for the purpose of becoming a bank holding company. Through August 2004, the Company was registered with the Federal Reserve Board (“FRB”) as a bank holding company under the Bank Holding Company Act of 1956, as amended. In August 2004, the Company filed for, and was approved as, a Financial Holding Company under the Bank Holding Company Act. The Company currently conducts its business through its two subsidiaries: Evans Bank, N.A. (the “Bank”), a nationally chartered bank, and its subsidiary, Evans National Holding Corp. (“ENHC”); and Evans National Financial Services, LLC (“ENFS”) and its subsidiary, The Evans Agency LLC (“TEA”). Unless the context otherwise requires, the term “Company” refers collectively to Evans Bancorp, Inc. and its subsidiaries. The Company conducts its business through its subsidiaries. It does not engage in any other substantial business.  Regulatory Requirements  The Company is subject to the rules, regulations, and reporting requirements of various regulatory bodies, including the FRB, the Federal Deposit Insurance Corporation (“FDIC”), the Office of the Comptroller of the Currency (“OCC”), the New York State Department of Financial Services (“the NYSDFS”), and the SEC.  Principles of Consolidation  The consolidated financial statements include the accounts of the Company, the Bank, ENFS and their subsidiaries. All material inter-company accounts and transactions are eliminated in consolidation.  Accounting Estimates  Management has made a number of estimates and assumptions relating to the reporting of assets and liabilities and disclosure of contingent assets and liabilities in order to prepare these consolidated financial statements in conformity with U.S. generally accepted accounting principles. The estimates and assumptions that management deems to be critical involve our accounting policies relating to the determination of our allowance for loan losses and the valuation of goodwill. These estimates and assumptions are based on management’s best estimates and judgment and management evaluates them on an ongoing basis using historical experience and other factors, including the current economic environment, which management believes to be reasonable under the circumstances. We adjust our estimates and assumptions when facts and circumstances dictate. As future events cannot be determined with precision, actual results could differ significantly from our estimates. Changes in those estimates resulting from continuing changes in the economic environment will be reflected in the consolidated financial statements in periods as they occur.  Cash and Cash Equivalents  For purposes of reporting cash flows, cash and cash equivalents include cash and due from banks and interest-bearing deposits at banks.  Securities  Securities which the Bank has the positive intent and ability to hold to maturity are classified as held to maturity and are stated at cost, adjusted for discounts and premiums that are recognized in interest income over the period to the earlier of the call date or maturity using the level yield method. These securities represent debt issuances of local municipalities in the Bank’s market area for which market prices are not readily available. Management periodically evaluates the financial condition of the municipalities for any indication that the Bank does not expect to recover the entire amortized cost basis of their bonds. Securities classified as available for sale are stated at fair value with unrealized gains and losses excluded from earnings and reported, net of deferred income taxes, in accumulated other comprehensive income or loss, a component of stockholders’ equity. Gains and losses on sales of securities are computed using the specific identification method.  Declines in the fair value of investment securities (with certain exceptions for debt securities noted below) that are deemed to be other-than-temporary are charged to earnings as a realized loss and a new cost basis for the securities is established. Declines in the fair value of debt securities below amortized cost are deemed to be other-than-temporary in circumstances where: (1) the Bank has the intent to sell a security; (2) it is more likely than not that the Bank will be required to sell the security before recovery of its amortized cost basis; or (3) the Bank does not expect to recover the entire amortized cost basis of the security. If the Bank intends to sell a security or if it is more likely than not that the Bank will be required to sell the security before recovery, an other-than-temporary impairment write-down is recognized in earnings equal to the difference between the security’s amortized cost basis and its fair value. If the Bank does not intend to sell the security or it is not more likely than not that it will be required to sell the security before recovery, the other-than-temporary impairment write-down is separated into an amount representing credit loss, which is recognized in earnings, and an amount related to all other factors, which is recognized in other comprehensive income. There were no charges associated with other-than-temporary impairment declines in fair value of securities in 2017, 2016, or 2015.  The Bank does not engage in securities trading activities.  Loans  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 unamortized deferred fees or costs. Interest income is accrued on the unpaid principal balance and is recognized using the interest method. Loan origination fees, net of certain direct origination costs, are deferred and recognized as an adjustment of the related loan yield using the effective yield method of accounting for amortizing loans and straight line over an estimated life for lines of credit.  Loans become past due when the payment date has been missed. If payment has not been received within 30 days, then the loan is delinquent. Delinquent loans are placed into three categories; 30-59 days past due, 60-89 days past due, or 90+ days past due. Loans 90 or more days past due are considered non-performing.  The accrual of interest on loans is discontinued at the time the loan is 90 days delinquent, unless the credit is well secured and in process of collection. If the credit is not well secured and in the process of collection, the loan is placed on non-accrual status and is subject to charge-off if collection of principal or interest is considered doubtful. A loan can also be placed on nonaccrual before it is 90 days delinquent if management determines that it is probable that the Bank will be unable to collect principal or interest due according to the contractual terms of the loan.  All interest due but not collected for loans that are placed on non-accrual status or charged off is reversed against interest income. The interest on these loans is accounted for on the cost-recovery method, until it again qualifies for an accrual basis. Any cash receipts on non-accrual loans reduce the carrying value of the loans. Loans are returned to accrual status when all principal and interest amounts contractually due are brought current, the adverse circumstances which resulted in the delinquent payment status are resolved, and payments are made in a timely manner for a period of time sufficient to reasonably assure their future dependability.  The Bank considers a loan impaired when, based on current information and events, it is probable that it will be unable to collect principal or interest due according to the contractual terms of the loan. These loans are individually assessed for any impairment. Loan impairment is measured based on the present value of expected cash flows discounted at the loan’s effective interest rate or, as a practical expedient, at the loan’s observable market price or the fair value of the collateral, less costs to sell, if the loan is collateral dependent. Appraised and reported values may be discounted based on management’s historical knowledge, changes in market conditions from the time of valuation, estimated costs to sell, and/or management’s expertise and knowledge of the client and the client’s business. The Company has an appraisal policy in which appraisals are obtained upon a loan being downgraded on the Company’s internal loan rating scale to a 5 (special mention) or a 6 (substandard) depending on the amount of the loan, the type of loan and the type of collateral. All impaired nonaccrual loans are either graded a 6 or 7 on the internal loan rating scale. Subsequent to the downgrade, if the loan remains outstanding and impaired for at least one year more, management may require another follow-up appraisal. Between receipts of updated appraisals, if necessary, management may perform an internal valuation based on any known changing conditions in the marketplace such as sales of similar properties, a change in the condition of the collateral, or feedback from local appraisers. The Bank monitors the credit risk in its loan portfolio by reviewing certain credit quality indicators (“CQI”). The primary CQI for its commercial mortgage and commercial and industrial (“C&I”) portfolios is the individual loan’s credit risk rating. The following list provides a description of the credit risk ratings that are used internally by the Bank when assessing the adequacy of its allowance for loan losses:  · 1-3-Pass: Risk Rated 1-3 loans are loans with a slight risk of loss. The loan is secured by collateral of sufficient value to cover the loan by an acceptable margin. The financial statements of the company demonstrate sufficient net worth and repayment ability. The company has established an acceptable credit history with the bank and typically has a proven track record of performance. Management is experienced, and has an at least average ability to manage the company. The industry has an average or less than average susceptibility to wide fluctuations in business cycles. · 4-Watch: Although generally acceptable, a higher degree of risk is evident in these watch credits. Obligor assessment factors may have elements which reflect marginally acceptable conditions warranting more careful review and analysis and monitoring.  The obligor’s balance sheet reflects generally acceptable asset quality with some elements weak or marginally acceptable. Liquidity may be somewhat strained, but is at an acceptable level to support operations. Obligor may be fully leveraged with ratios higher than industry averages. High leverage is negatively impacting the company, leaving it vulnerable to adverse change. Inconsistent or declining capability to service existing debt requirements evidenced by debt service coverage temporarily below or near acceptable level. The margin of collateral may be adequate, but declining or fluctuating in value. Company management may be unproven, but capable. Rapid expansion or acquisition may increase leverage or reduce cash flow.  Negative industry conditions or weaker management could also be characteristic. Proper consideration should be given to companies in a high growth phase or in development business segments that may not have achieved sustainable earnings.  Obligors demonstrate sufficient financial flexibility to react to and positively address the root cause of the adverse financial trends without significant deviations from their current business strategy. The rating is also used for borrowers that have made significant progress in resolving their financial weaknesses.  · 5-O.A.E.M. (Other Assets Especially Mentioned): Special Mention (“SM”) – A special mention asset has potential weaknesses that warrant management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the asset or in the institution’s credit position at some future date.  SM assets have potential weaknesses that may, if not checked or corrected, weaken the asset or inadequately protect the institution’s position at some future date. These assets pose elevated risk, but their weakness does not yet justify a substandard classification. Borrowers may be experiencing adverse operating trends (declining revenues or margins) or an ill proportioned balance sheet (e.g. increasing inventory without an increase in sales, high leverage, tight liquidity).  Adverse economic or market conditions, such as interest rate increases or the entry of a new competitor, may also support a special mention rating. Nonfinancial reasons for rating a credit exposure special mention include management problems, pending litigation, an ineffective loan agreement or other material structural weakness, and any other significant deviation from prudent lending practices.  The SM rating is designed to identify a specific level of risk and concern about asset quality. Although an SM asset has a higher probability of default than a pass asset, its default is not imminent.  · 6-Substandard: A substandard asset is inadequately protected by the current sound worth and paying capacity of the obligor or of the collateral pledged, if any. Assets so classified must have a well-defined weakness, or weaknesses, that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the Bank will sustain some loss if the deficiencies are not corrected.  Substandard assets have a high probability of payment default, or they have other well-defined weaknesses. They require more intensive supervision by Bank management.  Substandard assets are generally characterized by current or expected unprofitable operations, inadequate debt service coverage, inadequate liquidity, or marginal capitalization. Repayment may depend on collateral or other credit risk subsidies. For some substandard assets, the likelihood of full collection of interest and principal may be in doubt; such assets should be placed on non-accrual. Although substandard assets in the aggregate will have distinct potential for loss, an individual asset’s loss potential does not have to be distinct for the asset to be rated substandard. These loans are periodically reviewed and tested for impairment.  · 7-Doubtful: An asset classified doubtful has all the weaknesses inherent in one classified substandard with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable.  A doubtful asset has a high probability of total or substantial loss, but because of specific pending events that may strengthen the asset, its classification of loss is deferred.  Doubtful borrowers are usually in default, lack adequate liquidity or capital, and lack the resources necessary to remain an operating entity. Pending events can include mergers, acquisitions, liquidations, capital injections, the perfection of liens on additional collateral, the valuation of collateral, and refinancing.  Generally, pending events should be resolved within a relatively short period and the ratings will be adjusted based on the new information. Because of high probability of loss, non-accrual accounting treatment is required for doubtful assets.  · 8-Loss: Assets classified loss are considered uncollectable and of such little value that their continuance as bankable assets is not warranted. This classification does not mean that the assets have absolutely no recovery or salvage value, but rather that it is not practical or desirable to defer writing off this basically worthless asset even though partial recovery may be affected in the future.  With loss assets, the underlying borrowers are often in bankruptcy, have formally suspended debt repayments, or have otherwise ceased normal business operations. Once an asset is classified loss, there is little prospect of collecting either its principal or interest. When access to collateral, rather than the value of the collateral, is a problem, a less severe classification may be appropriate. Losses are to be recorded in the period an obligation becomes uncollectible.  The Company’s consumer loans, including residential mortgages and home equities, are not individually risk rated or reviewed in the Company’s loan review process. Consumers are not required to provide the Company with updated financial information as is a commercial customer. Consumer loans also carry smaller balances. Given the lack of updated information since the initial underwriting of the loan and small size of individual loans, the Company does not have credit risk ratings for consumer loans and instead uses delinquency status as the credit quality indicator for consumer loans. However, once a consumer loan is identified as impaired, it is individually evaluated for impairment.  Allowance for Loan Losses  The provision for loan losses represents the amount charged against the Bank’s earnings to maintain an allowance for loan losses inherent in the portfolio based on management’s evaluation of the loan portfolio at the balance sheet date. Factors considered by the Bank’s management in establishing the allowance include: the collectability of individual loans, current loan concentrations, charge-off history, loss emergence period, delinquent loan percentages, the fair value of the collateral, input from regulatory agencies, and general economic conditions.  On a quarterly basis, management of the Bank meets to review and determine the adequacy of the allowance for loan losses. In making this determination, the Bank’s management analyzes the ultimate collectability of the loans in its portfolio by incorporating feedback provided by the Bank’s internal loan staff, an independent internal loan review function and information provided by examinations performed by regulatory agencies.  The analysis of the allowance for loan losses is composed of two components: specific credit allocation and general portfolio allocation. The specific credit allocation includes a detailed review of each impaired loan and allocation is made based on this analysis. Factors may include the appraisal value of the collateral, the age of the appraisal, the type of collateral, the performance of the loan to date, the performance of the borrower’s business based on financial statements, and legal judgments involving the borrower. The general portfolio allocation consists of an assigned reserve percentage based on the historical loss experience, the loss emergence period, and other qualitative factors of the loan category.  The general portfolio allocation is segmented into homogeneous pools of loans with similar characteristics. Separate pools of loans include loans pooled by loan grade and by portfolio segment. An average historical loss rate over the past six years multiplied by the loss emergence period factor is applied against these loans.  For both the criticized and non-criticized loan pools in the general portfolio allocation, additional qualitative factors are applied. The qualitative factors applied to the general portfolio allocation reflect management’s evaluation of various conditions. The conditions evaluated include the following: levels and trends in delinquencies, non-accruals, and criticized loans; trends in volume and terms of loans; effects of any changes in lending policies and credit quality underwriting standards; experience, ability, and depth of management; national and economic trends and conditions; changes in the quality of the loan review system; concentrations of credit risk; changes in collateral value; and large loan risk. The total possible qualitative allocation is determined by comparing peer bank historical charge-off rates to the Bank’s historical charge-off rate. The actual qualitative allocation is determined by qualitative factor by loan type based on metrics that management believes are appropriate indicators of whether the Bank is in a low, moderate, or high risk range relative to historical experience for each qualitative factor.  Foreclosed Real Estate  Foreclosed real estate is initially recorded at the lower of carrying or fair value (net of costs of disposal) at the date of foreclosure. Costs relating to development and improvement of property are capitalized, whereas costs relating to the holding of property are expensed. Assessments are periodically performed by management, and an allowance for losses is established through a charge to operations if the carrying value of a property exceeds fair value. The Company held no foreclosed real estate at December 31, 2017 or December 31, 2016.    Insurance Commissions and Fees  Commission revenue is recognized as of the effective date of the insurance policy. The Company also receives contingent commissions from insurance companies which are based on the overall profitability of their relationship based primarily on the loss experience of the insurance placed by the Company. Contingent commissions from insurance companies are recognized when determinable.  Goodwill and Other Intangible Assets  The Company accounts for goodwill and other intangible assets in accordance with ASC Topic 350, "Intangibles – Goodwill and Other." The Company records the excess of the cost of acquired entities over the fair value of identifiable tangible and intangible assets acquired, less liabilities assumed, as goodwill. The Company amortizes acquired intangible assets with definite useful economic lives over their useful economic lives utilizing the straight-line method. On a periodic basis, management assesses whether events or changes in circumstances indicate that the carrying amounts of the intangible assets may be impaired. The Company does not amortize goodwill and any acquired intangible asset with an indefinite useful economic life, but reviews them for impairment at a reporting unit level on an annual basis, or when events or changes in circumstances indicate that the carrying amounts may be impaired. A reporting unit is defined as any distinct, separately identifiable component of one of our operating segments for which complete, discrete financial information is available and reviewed regularly by the segment’s management. The only reporting unit with goodwill as of December 31, 2017 was the insurance agency activities reporting unit.  The fair value of the insurance agency activities reporting unit is measured annually as of December 31st utilizing the average of a discounted cash flow model and a market value based on a multiple to earnings before interest, taxes, depreciation, and amortization (“EBITDA”) for similar companies. The calculated value of the insurance agency reporting unit was in excess of the carrying amount at December 31, 2017. The Company has performed the required goodwill impairment tests and has determined that goodwill was not impaired as of December 31, 2017.  Bank-Owned Life Insurance  The Bank has purchased insurance on the lives of Company directors and certain members of the Bank's and TEA's management. The policies accumulate asset values to meet future liabilities, including the payment of employee benefits, such as retirement benefits. Increases in the cash surrender value are recorded as other income in the Company’s Consolidated Statements of Income.  Properties and Equipment  Properties and equipment are stated at cost less accumulated depreciation. Depreciation is computed using the straight-line method over the estimated useful lives of the assets, which range from 3 to 39 years. Impairment losses on properties and equipment are realized if the carrying amount is not recoverable from its undiscounted cash flows and exceeds its fair value in accordance with ASC Topic 360, “Property, Plant, and Equipment.”  Income Taxes  Deferred tax assets and liabilities are recognized for the future tax effects attributable to differences between the financial statement value of existing assets and liabilities and their respective tax bases and carryforwards. Deferred tax assets and liabilities are reflected at currently enacted income tax rates applicable to the periods in which the deferred tax assets or liabilities are expected to be realized or settled. As changes in tax laws or rates are enacted, deferred tax assets and liabilities are adjusted through income tax expense.  The Bank has invested in partnerships that incur expenses related to the rehabilitation of a certified historic structure located in New York State. At the time the historic structure is placed in service, the Bank is eligible for a federal and New York State tax credit. At the same time, the Bank evaluates its investment, which is valued at the present value of the expected cash flows from its partnership interest. If the investment is determined to be impaired, the Bank will record that impairment loss on its income statement in non-interest income. The federal tax credit impact is included in the Company’s estimated effective tax rate calculation and recorded in income tax expense. For New York State, any new credit earned from rehabilitated historic properties placed in service on or after January 1, 2015 not used in the current tax year will be treated as a refund or overpayment of tax to be credited to the next year’s tax. Since the realization of the tax credit does not depend on the Bank’s generation of future taxable income or the Bank’s ongoing tax status or tax position, the refund is not considered an element of income tax accounting (ASC 740). In such cases, the Bank would not record the credit as a reduction of income tax expense; rather, the Bank includes the refundable New York State tax credit in non-interest income with a corresponding receivable recorded in other assets.  The Tax Cuts and Jobs Act (“TCJA”), which represents one of the most significant overhauls to the United States federal tax code since 1986, was signed into law on December 22, 2017. The TCJA reduces the Company’s marginal federal income tax rate from 35% to 21%, but also reduces the benefit of historic tax credit investments. The impact of the TCJA on the Company is detailed in Note 13 to the Consolidated Financial Statements. In addition to the decrease in the marginal federal income tax rate, there are many other provisions in the TCJA that affect corporations generally but are not expected to impact the Company including limits on the deductibility of FDIC insurance premium for banks with more than $10 billion in assets, various provisions related to companies with international operations, and limitations on the deductibility of interest expense.  Earnings Per Share  Earnings per common share is determined by dividing net income by the weighted average number of shares outstanding during the period. Diluted earnings per common share is based on increasing the weighted-average number of shares of common stock by the number of shares of common stock that would be issued assuming the exercise of stock options. Such adjustments to weighted-average number of shares of common stock outstanding are made only when such adjustments are expected to dilute earnings per common share. There were 122,434 , 76,632 , and 72,320 potentially dilutive shares of common stock included in calculating diluted earnings per share for the years ended December 31, 2017, 2016, and 2015, respectively. Potential common shares that would have the effect of increasing diluted earnings per share are considered to be anti-dilutive. In accordance with ASC Topic 260, "Earnings Per Share," these shares were not included in calculating diluted earnings per share. There were no anti-dilutive shares at each of December 31, 2017 and 2016. As of December 31, 2015, there were 36 thousand shares that were not included in calculating diluted earnings per share because their effect was anti-dilutive.  Treasury Stock  Repurchases of shares of Evans Bancorp, Inc. stock are recorded at cost as a reduction of shareholders’ equity. Reissuances of shares of treasury stock are recorded at market value.  Comprehensive Income  Comprehensive income includes both net income and other comprehensive income, including the change in unrealized gains and losses on securities available for sale, and the change in the liability related to pension costs, net of tax.  Employee Benefits  The Bank maintains a non-contributory, qualified, defined benefit pension plan (the “Pension Plan”) that covered substantially all employees before it was frozen on January 31, 2008. All benefits eligible participants had accrued in the Pension Plan until the freeze date have been retained. Employees have not accrued additional benefits in the Pension Plan from that date. The actuarially determined pension benefit in the form of a life annuity is based on the employee’s combined years of service, age and compensation. The Bank’s policy is to fund the minimum amount required by government regulations. Employees are eligible to receive these benefits at normal retirement age.  The Bank maintains a defined contribution 401(k) plan and accrues contributions due under this plan as earned by employees. In addition, the Bank maintains a non-qualified Supplemental Executive Retirement Plan for certain members of senior management, a non-qualified Deferred Compensation Plan for directors and certain members of management, and a non-qualified Executive Incentive Retirement Plan for certain members of management, as described more fully in Note 11 to these Consolidated Financial Statements, “Employee Benefits and Deferred Compensation Plans.”  Stock-based Compensation  Stock-based compensation expense is recognized over the vesting period of the stock-based grant based on the estimated grant date value of the stock-based compensation that is expected to vest. Information on the determination of the estimated value of stock-based awards used to calculate stock-based compensation expense is included in Note 12 to these Consolidated Financial Statements, “Stock-Based Compensation.”  ASU 2016-09, Improvements to Employee Share-Based Payment Accounting , was adopted effective January 1, 2017. This ASU is part of the FASB’s Simplification Initiative. The areas for simplification in this Update involve several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. Some of the areas of simplification apply only to nonpublic entities. One part of this ASU that impacted the Company was the elimination of the concept of a tax windfall pool. Previously, an entity determined for each award whether the difference between the deduction for tax purposes and the compensation cost recognized for financial reporting purposes resulted in either an excess benefit or a tax deficiency. Excess tax benefits were recognized in additional paid-in-capital; tax deficiencies were recognized either as an offset to accumulated excess tax benefits, if any, or in the income statement. Excess tax benefits were not recognized until the deduction reduced taxes payable. Under the new standard, all excess tax benefits and tax deficiencies are recognized as income tax expense or benefit in the income statement in the period in which they are incurred. The impact on the Company was a tax benefit of $0.2 million for the year ended December 31, 2017.  In addition, the Company made the accounting policy election effective January 1, 2017 to account for forfeitures of stock awards when they occur rather than estimating the number of awards that are expected to vest. When stock awards are granted, the Company assumes that the service condition will be achieved when determining the initial amount of compensation cost recognized. This election has not had a material impact on the Company’s financial statements.  Loss Contingencies  Loss contingencies, including claims and legal actions arising in the ordinary course of business, are recorded as liabilities when the likelihood of loss is probable and an amount or range of loss can be reasonably estimated.  Financial Instruments with Off-Balance Sheet Risk  In the ordinary course of business, the Bank has entered into off-balance sheet financial arrangements consisting of commitments to extend credit and

The scheduled maturity of debt and mortgage-backed securities at December 31, 2017 and 2016 is summarized below. All maturity amounts are contractual maturities.

There were no realized gains and losses from gross sales of securities in 2017, 2016 or 2015.  Information regarding unrealized losses within the Company’s available for sale securities at December 31, 2017 and 2016 is summarized below. The securities are primarily U.S. government-guaranteed agency securities or municipal securities.

In making this determination, management considered the period of time the securities were in a loss position, the percentage decline in comparison to the securities’ amortized cost, and the financial condition of the issuer (primarily government or government-sponsored enterprises). In addition, management does not intend to sell these securities and it is not more likely than not that the Company will be required to sell these securities before recovery of their amortized cost. Management believes the decline in fair value is primarily related to market interest rate fluctuations and not to the credit deterioration of the individual issuers. The Company holds no securities backed by sub-prime or Alt-A residential mortgages or commercial mortgages and also does not hold any trust-preferred securities.  The Company did not record any other-than-temporary impairment charges in 2017, 2016, or 2015. The credit worthiness of the Company’s portfolio is largely reliant on the ability of U.S. government agencies such as the Federal Home Loan Bank (“FHLB”), Federal National Mortgage Association (“FNMA”), and the Federal Home Loan Mortgage Corporation (“FHLMC”), and municipalities throughout New York State to meet their obligations. In addition, dysfunctional markets could materially alter the liquidity, interest rate, and pricing risk of the portfolio. The stable past performance is not a guarantee for similar performance going forward.

Loans And The Allowance For Loan Losses [Abstract]
Loans And The Allowance For Loan Losses	3. LOANS AND THE ALLOWANCE FOR LOAN LOSSES  Major categories of loans at December 31, 2017 and 2016 are summarized as follows:    December 31, 2017 December 31, 2016  Mortgage loans on real estate: (in thousands)  Residential mortgages $ 131,208 $ 118,542  Commercial and multi-family 519,902 462,385  Construction-Residential 2,134 2,540  Construction-Commercial 107,274 93,240  Home equities 69,745 66,234  Total real estate loans 830,263 742,941   Commercial and industrial loans 232,211 197,371  Consumer and other loans 1,654 1,417  Net deferred loan origination costs 1,187 783  Total gross loans 1,065,315 942,512   Allowance for loan losses (14,019) (13,916)   Loans, net $ 1,051,296 $ 928,596   Residential Mortgages : The Company originates adjustable-rate and fixed-rate, one-to-four-family residential real estate loans for the construction, purchase, or refinancing of a mortgage. These loans are collateralized by owner-occupied properties located in the Company’s market area and are amortized over a period of 10 to 30 years. Loans on one-to-four-family residential real estate are mostly originated in amounts of no more than 80% of the property’s appraised value or have private mortgage insurance. Mortgage title insurance and hazard insurance are normally required. Construction loans have a unique risk, because they are secured by an incomplete dwelling.  The Bank, in its normal course of business, sells certain residential mortgages which it originates to FNMA. The Company maintains servicing rights on the loans that it sells to FNMA and earns a fee thereon. The Bank determines with each origination of residential real estate loans which desired maturities, within the context of overall maturities in the loan portfolio, provide the appropriate mix to optimize the Bank’s ability to absorb the corresponding interest rate risk within the Company’s tolerance ranges. This practice allows the Company to manage interest rate risk, liquidity risk, and credit risk. At December 31, 2017 and 2016, the Company had approximately $78 million and $76 million, respectively, in unpaid principal balances of loans that it services for FNMA. For the years ended December 31, 2017 and 2016, the Company sold $11 million and $10 million, respectively, in loans to FNMA and realized gains on those sales of $ 156 thousand and $ 93 thousand, respectively. Gains or losses recognized upon the sale of loans are determined on a specific identification basis. The Company had a related asset of approximately $0.6 and $0.5 million for the servicing portfolio rights as of December 31, 2017 and 2016, respectively. No loans were held for sale at December 31, 2017 compared with $0.3 million in loans held for sale at December 31, 2016. Loans held for sale are typically in the portfolio for less than a month. As a result, the carrying value approximates fair value. The Company has never been contacted by FNMA to repurchase any loans due to improper documentation or fraud.  Due to the lack of foreclosure activity and absence of any ongoing litigation at December 31, 2017 and 2016, the Company had no accrual for loss contingencies or potential costs associated with foreclosure-related activities at those dates.  Commercial and Multi-Family Mortgages and Commercial Construction Loans : Commercial real estate loans are made to finance the purchases of real estate with completed structures or in the midst of being constructed. These commercial real estate loans are secured by first liens on the real estate, which may include apartments, hotels, retail stores or plazas, healthcare facilities, and other non-owner-occupied facilities. These loans are generally less risky than commercial and industrial loans, since they are secured by real estate and buildings. The Company offers commercial mortgage loans with up to an 80% LTV ratio for up to 20 years on a variable and fixed rate basis. Many of these mortgage loans either mature or are subject to a rate call after three to five years. The Company’s underwriting analysis includes credit verification, independent appraisals, a review of the borrower's financial condition, and the underlying cash flows. Construction loans have a unique risk, because they are secured by an incomplete dwelling.  As of December 31, 2017, there were $228 million in residential and commercial mortgage loans pledged to FHLBNY to serve as collateral for borrowings.  Home Equities : The Company originates home equity lines of credit and second mortgage loans (loans secured by a second lien position on one-to-four-family residential real estate). These loans carry a higher risk than first mortgage residential loans because they are in a second position with respect to collateral. Risk is reduced through underwriting criteria, which include credit verification, appraisals, a review of the borrower's financial condition, and personal cash flows. A security interest, with title insurance when necessary, is taken in the underlying real estate.  Commercial and Industrial Loans: These loans generally include term loans and lines of credit. Such loans are made available to businesses for working capital (including inventory and receivables), business expansion (including acquisition of real estate, expansion, and improvements) and equipment purchases. As a general practice, a collateral lien is placed on equipment or other assets owned by the borrower. These loans generally carry a higher risk than commercial real estate loans based on the nature of the underlying collateral, which can be business assets such as equipment and accounts receivable. To reduce the risk, management also attempts to secure real estate as collateral and obtain personal guarantees of the borrowers. To further reduce risk and enhance liquidity, these loans generally carry variable rates of interest, re-pricing in three - to five -year periods, and have a maturity of five years or less. Lines of credit generally carry floating rates of interest (e.g. prime plus a margin).  Consumer Loans : The Company funds a variety of consumer loans, including direct automobile loans, recreational vehicle loans, boat loans, home improvement loans, and personal loans (collateralized and uncollateralized). Most of these loans carry a fixed rate of interest with principal repayment terms typically ranging up to five years, based upon the nature of the collateral and the size of the loan. The majority of consumer loans are underwritten on a secured basis using the underlying collateral being financed. A minimal amount of loans are unsecured, which carry a higher risk of loss. These loans included overdrawn deposit accounts classified as loans of less than $0.1 million at December 31, 2017 and 2016.  The Company maintains an allowance for loan losses in order to capture the probable losses inherent in its loan portfolio. There is a risk that the Company may experience significant loan losses in 2018 and beyond which could exceed the allowance for loan losses. If the Company's assumptions and judgments prove to be incorrect or bank regulators require the Company to increase its provision for loan losses or recognize further loan charge-offs, the Company may have to increase its allowance for loan losses or loan charge-offs which could have a material adverse effect on the Company's operating results and financial condition. There can be no assurance that the Company's allowance for loan losses will be adequate to protect the Company against loan losses that it may incur.

Each commercial relationship is individually assigned a risk rating. The Company also maintains a loan review process that monitors the management of the Company’s commercial loan portfolio by the relationship managers. The Company’s loan review function reviews at least 40% of the commercial loan portfolio annually.  The Company’s consumer loans, including residential mortgages and home equity loans and lines of credit, are not individually risk rated or reviewed as part of the Company’s loan review process. Unlike commercial customers, consumer loan customers are not required to provide the Company with updated financial information. Consumer loans also carry smaller dollar balances. Given the lack of updated information since the initial underwriting of the loan and the small size of individual loans, the Company uses delinquency status as the primary credit quality indicator for consumer loans. Once a consumer loan reaches 60 days past due, management orders an independent appraisal of the underlying collateral and produces a credit report on the borrower. After discounting for potential selling costs and other factors specific to the property or borrower, the book value of the loan is then compared to the collateral value as determined by the appraisal. In situations where the Company holds a junior lien, management accounts for the amount of the senior liens held by other lenders, and the collateral value is more heavily discounted to account for the increased risk. If the loan is ultimately determined to be impaired, it is placed in non-accrual status. Unless the loan is well secured and in the process of collection, all consumer loans that are more than 90 days past due are placed in non-accrual status.

As management identifies impaired loans that are collateral dependent, new appraisals are ordered to determine the fair value of the collateral. It should also be noted that when estimating the fair value of collateral for the purpose of performing an impairment test, management further reduces the appraised value of the collateral to account for estimated selling or carrying costs, age of the appraisal, if applicable, or any other perceived market or borrower-specific risks to the value of the collateral.  The interest income in the preceding table was interest income recognized on accruing TDRs and interest paid prior to loans being identified as non-accrual. The interest income foregone in the preceding table represents interest income that the Company did not recognize on those loans while they were on non-accrual.  The Bank had no loan commitments to borrowers in non-accrual status at December 31, 2017 and 2016.  Troubled debt restructurings (“TDRs”)  The Company had $7.3 million in loans that were restructured and deemed to be TDRs at December 31, 2017 with $4.4 million of those balances in non-accrual status. Any new TDR that is placed on non-accrual is not returned to accruing status until the borrower makes timely payments as contracted for at least six months and future collection under the revised terms is probable. All of the restructurings were allowed in an effort to maximize the Company’s ability to collect on loans where borrowers were experiencing financial difficulty. The reserve for a TDR is based upon the present value of the future expected cash flows discounted at the loan’s original effective rate or upon the fair value of the collateral less costs to sell, if the loan is deemed collateral dependent. This reserve methodology is used because all TDR loans are considered impaired.  The following table presents the Company’s TDR loans as of December 31, 2017, and 2016, respectively:      December 31, 2017  (in thousands)  Total Nonaccruing Accruing Related Allowance  Commercial and industrial $ 734 $ 220 $ 514 $ 8  Residential real estate:  Residential 1,656 271 1,385 -  Construction - - - -  Commercial real estate:  Commercial and multi-family 3,854 3,767 87 236  Construction 187 - 187 -  Home equities 794 128 666 -  Consumer and other 25 - 25 24  Total TDR loans $ 7,250 $ 4,386 $ 2,864 $ 268       December 31, 2016  (in thousands)  Total Nonaccruing Accruing Related Allowance  Commercial and industrial $ 574 $ 532 $ 42 $ 147  Residential real estate:  Residential 1,949 227 1,722 -  Construction - - - -  Commercial real estate:  Commercial and multi-family 1,617 313 1,304 -  Construction 257 - 257 -  Home equities 667 175 492 1  Consumer and other 26 - 26 26  Total TDR loans $ 5,090 $ 1,247 $ 3,843 $ 174   The Company’s TDRs have various agreements that involve deferral of principal payments, or interest-only payments, for a period (usually 12 months or less) to allow the customer time to improve cash flow or sell the property. Other common types of concessions leading to the designation of a TDR are lines of credit that are termed-out and extensions of maturities at rates that are less than prevailing market rates given the risk profile of the borrower.

All of the C&I and commercial real estate TDRs were already considered impaired and sufficiently reserved for prior to being identified as a TDR.  At December 31, 2017, there were no commitments to lend additional funds to debtors owing loans whose terms have been modified in TDRs.  The general practice of the Bank is to work with borrowers so that they are able to repay their loan in full. If a borrower continues to be delinquent or cannot meet the terms of a TDR and the loan is determined to be uncollectible, the loan will be charged-off to its collateral value. A loan is considered in default when the loan is 90 days past due.

Goodwill And Intangible Assets	6. GOODWILL AND INTANGIBLE ASSETS  The Company had $8.1 million in goodwill at each of December 31, 2017 and 2016. The entire amount of goodwill is within the insurance agency activities segment. The Company measures the fair value of the insurance agency reporting unit annually, as of December 31, utilizing market value EBITDA multiples based on industry data and cash flow modeling. When modeling future cash flows, management considered historical information, the operating budget, and strategic goals in projecting net income and cash flows for the next five years. No impairment was recognized as a result of the goodwill impairment test as of December 31, 2017 and 2016, respectively. Further discussion of the Company’s goodwill impairment testing is included in Note 1.  TEA purchased the assets of A.M. Smith Group, Inc., a local insurance agency in Lockport, NY, on December 31, 2016 and Mietus Agency in Derby, N.Y on January 1, 2017.

BORROWED FUNDS AND JUNIOR SUBORDINATED DEBENTURES  Other borrowings at December 31, 2017 consist of a $10 million advance from the FHLB with a fixed interest rate of 1.73% that matures in 2020 and a FHLB Overnight Line of Credit advance of $78 million.   The Bank has the ability to borrow additional funds from the FHLB based on the securities or real estate loans that can be used as collateral and to purchase additional federal funds through one of the Bank’s correspondent banks. Given the current collateral available, additional advances of up to $164 million can be drawn on the FHLB via the Bank’s Overnight Line of Credit Agreement. The Bank also has the ability to purchase up to $1 8 million in federal funds from its correspondent banks.  As a member of the Federal Home Loan Bank System, the Bank is required to hold stock in FHLBNY. The Bank held FHLBNY stock with a carrying value of $5 million and $2 million as of December 31, 2017 and December 31, 2016, respectively.  The amounts and interest rates of other borrowed funds were as follows:     FHLB Overnight Line of Credit FHLB Advances Total Other Borrowings  (in thousands)  At December 31, 2017  Amount outstanding $ 78,250 $ 10,000 $ 88,250  Weighted-average interest rate 1.53 % 1.73 % 1.55 %   For the year ended December 31, 2017  Highest amount at a month end $ 78,250 $ 10,000  Daily average amount outstanding $ 16,491 $ 10,000 $ 26,491  Weighted-average interest rate 1.36 % 1.73 % 1.50 %   At December 31, 2016  Amount outstanding $ 18,200 $ 10,000 $ 28,200  Weighted-average interest rate 0.74 % 1.73 % 1.09 %   For the year ended December 31, 2016  Highest amount at a month end $ 49,100 $ 10,000  Daily average amount outstanding $ 16,011 $ 10,000 $ 26,011  Weighted-average interest rate 0.61 % 1.73 % 1.05 %   At December 31, 2015  Amount outstanding $ - $ 10,000 $ 10,000  Weighted-average interest rate - % 1.73 % 1.73 %   For the year ended December 31, 2015  Highest amount at a month end $ 17,700 $ 10,000  Daily average amount outstanding $ 2,504 $ 7,151 $ 9,655  Weighted-average interest rate 0.33 % 1.79 % 1.41 %  On October 1, 2004 , Evans Capital Trust I, a statutory business trust wholly-owned by the Company (the “Trust”), issued $11.0 million in aggregate principal amount of floating rate preferred capital securities due November 23, 2034 (the “Capital Securities”) classified on the Company’s consolidated balance sheets as Junior Subordinated Debentures. The distribution rate on the Capital Securities of the Trust adjusts quarterly based on changes in the three-month London Interbank Offered Rate (“LIBOR”) and was 4.10% at December 31, 2017.  The Capital Securities have a distribution rate of three-month LIBOR plus 2.65% , and the distribution dates are February 23, May 23, August 23, and November 23.  The common securities of the Trust (the “Common Securities”) are wholly-owned by the Company and are the only class of the Trust’s securities possessing general voting powers. The Capital Securities represent preferred undivided interests in the assets of the Trust. Under the Federal Reserve Board’s current risk-based capital guidelines, the Capital Securities are includable in the Company’s Tier 1 (Core) capital.  The proceeds from the issuances of the Capital Securities and Common Securities were used by the Trust to purchase $11.3 million in aggregate liquidation amount of floating rate junior subordinated deferrable interest debentures (“Junior Subordinated Debentures”) of the Company, due October 1, 2037 , which are comprised of $11.0 million of Capital Securities and $330 thousand of Common Securities. The $330 thousand of Common Securities represent the initial capital contribution of the Company to the Trust, which, in accordance with the provisions of ASC Topic 810 "Consolidation," have not been consolidated and are included in “Other Assets” on the consolidated balance sheet.  The Junior Subordinated Debentures represent the sole assets of the Trust, and payments under the Junior Subordinated Debentures are the sole source of cash flow for the Trust. The interest rate payable on the Junior Subordinated Debentures was 4.10% at December 31, 2017.  Holders of the Capital Securities receive preferential cumulative cash distributions on each distribution date at the stated distribution rate, unless the Company exercises its right to extend the payment of interest on the Junior Subordinated Debentures for up to twenty quarterly periods, in which case payment of distributions on the respective Capital Securities will be deferred for comparable periods. During an extended interest period, in accordance with terms as defined in the indenture relating to the Capital Securities, the Company may not pay dividends or distributions on, or repurchase, redeem, or acquire any shares of its capital stock. The agreements governing the Capital Securities, in the aggregate, provide a full, irrevocable, and unconditional guarantee by the Company of the payment of distributions on, the redemption of, and any liquidation distribution with respect to the Capital Securities. The obligations under such guarantee and the Capital Securities are subordinate and junior in right of payment to all senior indebtedness of the Company.  The Capital Securities will remain outstanding until the Junior Subordinated Debentures are repaid at maturity, are redeemed prior to maturity, or are distributed in liquidation to the Trust. The Capital Securities are mandatorily redeemable in whole, but not in part, upon repayment at the stated maturity dates of the Junior Subordinated Debentures or the earlier redemption of the Junior Subordinated Debentures in whole upon the occurrence of one or more events (“Events”) set forth in the indentures relating to the Capital Securities, and in whole or in part at any time contemporaneously with the optional redemption of the related Junior Subordinated Debentures in whole or in part. The Junior Subordinated Debentures are redeemable prior to their stated maturity dates at the Company’s option: (i) on or after the stated optional redemption dates, in whole at any time, or in part from time to time; or (ii) in whole, but not in part, at any time within 90 days following the occurrence and during the continuation of one or more of the Events, in each case subject to possible regulatory approval. The redemption price of the Capital Securities and the related Junior Subordinated Debentures upon early redemption would be at the liquidation amount plus accumulated but unpaid distributions.

Employee Benefits And Deferred Compensation Plans [Abstract]
Employee Benefits And Deferred Compensation Plans	 11. EMPLOYEE BENEFITS AND DEFERRED COMPENSATION PLANS  Employees’ Pension Plan The Bank has a defined benefit pension plan that covered substantially all employees of the Company and its subsidiaries (the “Pension Plan”). The Pension Plan provides benefits that are based on the employees’ compensation and years of service. The Bank uses an actuarial method of amortizing prior service cost and unrecognized net gains or losses which result from actual experience and assumptions being different than those that are projected. The amortization method the Bank uses recognizes the prior service cost and net gains or losses over the average remaining service period of active employees which exceeds the required amortization. The Pension Plan was frozen effective January 31, 2008. Under the freeze, eligible employees will receive the benefits already earned through January 31, 2008 at retirement, but will not be able to accrue any additional benefits. As a result, service cost will no longer be incurred.  Selected Financial Information for the Pension Plan is as follows:      12/31/2017 12/31/2016  Change in benefit obligation: (in thousands)  Benefit obligation at the beginning of the year $ 5,524 $ 5,384  Service cost - -  Interest cost 216 221  Assumption change 245 97  Actuarial (gain) loss 62 11  Benefits paid (205) (189)  Benefit obligation at the end of the year 5,842 5,524   Change in plan assets:  Fair value of plan assets at the beginning of year 4,266 4,067  Actual return on plan assets 726 248  Employer contributions 1,000 140  Benefits paid (205) (189)  Fair value of plan assets at the end of year 5,787 4,266   Funded status $ (55) $ (1,258)   Amount recognized in the Consolidated Balance Sheets consist of:  Accrued benefit liabilities $ (55) $ (1,258)   Amount recognized in the Accumulated Other Comprehensive Loss consists of:  Net actuarial loss $ 2,192 $ 2,429  Prior service cost - -  Net amount recognized in equity - pre-tax $ 2,192 $ 2,429   Net amount recognized on Consolidated Balance Sheets in Other Liabilities $ 2,137 $ 1,171   Accumulated benefit obligation at year end $ 5,842 $ 5,524   Assumptions used by the Bank in the determination of Pension Plan information consisted of the following:       2017 2016 2015  Discount rate for projected benefit obligation 3.55 % 3.95 % 4.17 %  Discount rate for net periodic pension cost 3.95 % 4.17 % 3.83 %  Rate of increase in compensation levels - % - % - %  Expected long-term rate of return of plan assets 6.50 % 6.50 % 7.50 %   The components of net periodic benefit cost consisted of the following:       2017 2016 2015  (in thousands)  Service cost $ - $ - $ -  Interest cost 216 221 205  Expected return on plan assets (275) (263) (308)  Net amortization and deferral 92 85 71  Net periodic benefit cost $ 33 $ 43 $ (32)   The estimated amounts to be amortized from accumulated other comprehensive loss into net periodic cost in 2018 for amortization of actuarial loss will be $80 thousand.  The Company contributed $1 million to the Pension Plan in 2017 and expects that it will no t contribute to the Pension Plan in 2018.  The expected long-term rate of return on Pension Plan assets assumption was determined based on historical returns earned by equity and fixed income securities, adjusted to reflect future return expectations based on plan targeted asset allocation. Equity and fixed income securities were assumed to earn returns in the ranges of 5% to 10% and 5% to 6% , respectively. When these overall return expectations are applied to the Pension Plan’s targeted allocation, the expected rate of return was determined to be 6.50% , which is within the range of expected return. The Company’s management will continue to evaluate its actuarial assumptions, including the expected rate of return, at least annually, and will adjust as necessary.  The weighted average asset allocation of the Pension Plan at December 31, 2017 and 2016, the Pension Plan measurement date, was as follows:      Asset Category: 2017 2016  Equity mutual funds 25.93 % 67.97 %  Fixed income mutual funds 72.17 % 30.20 %  Cash/Short-term investments 1.90 % 1.83 %  100.00 % 100.00 %  The portfolio is invested in accordance with sound investment practices that emphasize long-term investment fundamentals. Consistent with this approach, the investment strategy is to diversify the portfolio in order to reduce risk and to maintain sufficient liquidity to meet the obligations of the Plan. The Plan’s long-term asset allocation under normal market conditions shifted during 2017 from 65% equity investments and 35% in fixed income assets and other short term cash equivalents to 25% and 75% , respectively. The investment objective of the allocation in equity investments emphasizes long term capital appreciation. These equity investments are diversified across market capitalization, industries, style and geographical location. The investment objective of the fixed income allocation is to generally provide a diversified source of income with an awareness of capital preservation. Management decided to fully fund the Plan in 2017 with a $1 million contribution. As a result, the primary objective of the investment philosophy shifted from long term capital appreciation to capital preservation.  The major categories of assets in the Bank’s Pension Plan as of year-end are presented in the following table. Assets are segregated according to their investment objective by the level of the valuation inputs within the fair value hierarchy established by ASC Topic 820 utilized to measure fair value (see Note 19 – Fair Value of Financial Instruments).      2017 2016  (in thousands)  Level 1:  Mutual funds:  Short-term investments:  Money market $ 110 $ 78  Fixed Income: 4,176 1,288  Equities:  Small cap 243 307  Large cap 520 1,008  Real estate - 101  International large cap 497 923  International small cap 123 201  Emerging markets 118 254  Commodity - 106  $ 5,787 $ 4,266  The mutual funds are actively traded with market quotes available on at least a daily basis. Therefore, they are Level 1 assets.  The discount rate utilized by the Company for determining future pension obligations is based on a review of long-term bonds that receive one of the two highest ratings given by a recognized rating agency. The discount rate determined on this basis decreased from 3.95% at December 31, 2016 to 3.55% at December 31, 2017 for the Company's Pension Plan.  Expected benefit payments under the Pension Plan over the next ten years at December 31, 2017 are as follows:     (in thousands)  2018 $ 216  2019 214  2020 212  2021 227  2022 261  Year 2023 - 2027 1,629  Supplemental Executive Retirement Plans The Bank also maintains a non-qualified supplemental executive retirement plan (the “SERP”) covering certain members of the Company’s senior management. The SERP was amended during 2003 to provide a benefit based on a percentage of final average earnings, as opposed to the fixed benefit that was provided for in the superseded plan. On April 8, 2010, the Compensation Committee of the Board of Directors of the Company approved the adoption of the Evans Bank, N.A. Supplemental Executive Retirement Plan for Senior Executives (“the Senior Executive SERP”). The “old” SERP plan will keep its participants at the time of the creation of the Senior Executive SERP, but any future executives identified by the Board of Directors as eligible for SERP benefits will participate in the Senior Executive SERP. A participant is generally entitled to receive a benefit under the Senior Executive SERP upon a termination of employment, other than for “cause”, after the participant has completed 10 full calendar years of service with the Bank. No benefit is payable under the Senior Executive SERP if the participant’s employment is terminated for “cause” or if the participant voluntarily terminates before completing 10 full calendar years of service with the Bank. In addition, the payment of benefits under the Senior Executive SERP is conditioned upon certain agreements of the participant related to confidentiality, cooperation, non-competition, and non-solicitation. A participant will be entitled to a retirement benefit under the Senior Executive SERP if his or her employment with the Bank terminates other than for “cause”. The “accrued benefit” is based on a percentage of the participant’s final average earnings, which is determined based upon the participant’s total annual compensation over the highest consecutive five calendar years of the participant’s employment with the Bank, accrued over the participant’s “required benefit service”. The percentages and years of service requirements are set forth in each participant’s Participation Agreement, and range from 25% to 35% and from 15 to 20 years. The obligations related to the two SERP plans are indirectly funded by various life insurance contracts naming the Bank as beneficiary. The Bank has also indirectly funded the SERPs, as well as other benefits provided to other employees, through bank-owned life insurance. The Bank uses an actuarial method of amortizing unrecognized net gains or losses which result from actual experience and assumptions being different than those that are projected. The amortization method the Bank is using recognizes the net gains or losses over the average remaining service period of active employees, which exceeds the required amortization.  Selected financial information for the two SERP plans is as follows:      12/31/2017 12/31/2016  Change in benefit obligation: (in thousands)  Benefit obligation at the beginning of the year $ 4,255 $ 4,349  Service cost 168 188  Interest cost 137 144  Actuarial (gain) loss 175 (234)  Benefits paid (193) (192)  Benefit obligation at the end of the year 4,542 4,255   Change in plan assets:  Fair value of plan assets at the beginning of year - -  Actual return on plan assets - -  Employer contributions 193 192  Benefits paid (193) (192)  Fair value of plan assets at the end of year - -   Funded status $ (4,542) $ (4,255)   Amount recognized in the Consolidated Balance Sheets consist of:  Accrued benefit liabilities $ (4,542) $ (4,255)   Amount recognized in the Accumulated Other Comprehensive Loss consists of:  Net actuarial loss $ 841 $ 747  Prior service cost 156 187  Net amount recognized in equity - pre-tax $ 997 $ 934   Net amount recognized on Consolidated Balance Sheets in Other Liabilities $ (3,545) $ (3,321)   Accumulated benefit obligation at year end $ 4,007 $ 3,902  Assumptions used by the Bank in both years in the determination of SERP information consisted of the following:      2017 2016 2015  Discount rate for projected benefit obligation 3.09 % 3.30 % 3.38 %  Discount rate for net periodic pension cost 3.30 % 3.38 % 3.30 %  Salary scale 3.00 % 3.00 % 3.50 %  The discount rate utilized by the Company for determining future pension obligations is based on a review of long-term bonds that receive one of the two highest ratings given by a recognized rating agency. The discount rate determined on this basis decreased from 3.30% at December 31, 2016 to 3.09% at December 31, 2017 (i.e. the measurement date) for the SERP.  The components of net periodic benefit cost consisted of the following:     2017 2016 2015  (in thousands)  Service cost $ 168 $ 188 $ 194  Interest cost 137 144 146  Net amortization and deferral 112 167 161  Net periodic benefit cost $ 417 $ 499 $ 501   The estimated amounts to be amortized from accumulated other comprehensive loss into net periodic benefit cost in 2018 for prior service costs and actuarial loss will be $31 thousand and $86 thousand, respectively.  Expected benefit payments under the SERP over the next ten years at December 31, 2017 are as follows:      (in thousands)  2018 $ 193  2019 193  2020 193  2021 277  2022 2,841  Year 2023 - 2027 1,185 Other Compensation Plans  The Company has a non-qualified deferred compensation plan whereby directors and certain officers may defer a portion of their base pre-tax compensation. Additionally, the Company has a non-qualified executive incentive retirement plan, whereby the Company defers on behalf of certain officers a portion of their base compensation until retirement or termination of service, subject to certain vesting arrangements. Aggregate expense under these plans was approximately $107 thousand in 2017, $110 thousand in 2016, and $105 thousand in 2015. The benefit obligation, included in other liabilities in the Company’s consolidated balance sheets, was $2.0 million at December 31, 2017 and $2.2 million at each of December 31, 2016 and 2015.  These benefit plans are indirectly funded by bank-owned life insurance contracts with a total aggregate cash surrender value of approximately $27.7 million and $21.5 million at December 31, 2017 and 2016, respectively. Increases in cash surrender value are included in other non-interest income on the Company’s Consolidated Statements of Income. Endorsement split-dollar life insurance benefits have also been provided to directors and certain officers of the Bank and its subsidiaries during employment.  The Bank also has a defined contribution retirement and thrift 401(k) Plan (the “401(k) Plan”) for its employees who meet certain length of service and age requirements. The provisions of the 401(k) Plan allow eligible employees to contribute a portion of their annual salary, up to the IRS statutory limit. The 401(k) plan includes a Qualified Automatic Contribution Arrangement (“QACA”). This arrangement features automatic deferred contributions with annual escalation, a QACA matching contribution, and an additional matching contribution. Employees vest in employer contributions over six years. The Company’s expense under the 401(k) Plan was approximately $818 thousand, $727 thousand, and $751 thousand for the years ended December 31, 2017, 2016, and 2015, respectively.

Stock-Based Compensation [Abstract]
Stock-Based Compensation	12. STOCK-BASED COMPENSATION  At December 31, 2017, the Company had two stock-based compensation plans, which are described below. The Company accounts for the fair value of its grants under these plans in accordance with ASC Topic 718, “Compensation – Stock Compensation”. The compensation cost charged against income for those plans was $456 thousand, $380 thousand, and $318 thousand for 2017, 2016, and 2015, respectively, and is included in “Salaries and Employee Benefits” in the Company’s Consolidated Statements of Income. All stock option and restricted stock expense is recorded on a straight-line basis over the expected vesting term. In addition, expenses for director stock-based compensation were recognized to reflect $120 thousand, $98 thousand, and $106 thousand in 2017, 2016, and 2015, respectively, as part of “Other” expense in the Company’s Consolidated Statements of Income.  2009 Long-Term Equity Incentive Plan  Under the Company’s 2009 Long-Term Equity Incentive Plan (the “2009 Plan”) and, prior to the adoption of the 2009 Plan by shareholders in April 2009, under the Company’s 1999 Employee Stock Option and Long-Term Incentive Plan (the “1999 Plan” and together with the 2009 Plan, the “Equity Plans”), the Company has granted options or restricted stock to officers, directors and key employees of the Company and its subsidiaries. Under the Equity Plans, the Company was authorized to issue up to 629,796 shares of common stock. Under the Equity Plans, the exercise price of each option is not to be less than 100% of the market price of the Company’s stock on the date of grant and an option’s maximum term is ten years. If available, the Company normally issues shares out of its treasury for any options exercised or restricted shares issued. The options have vesting schedules from 12 months through 4 years. At December 31, 2017, there were a total of 107,824 shares available for grant under the 2009 Plan. The Company may no longer make grants under the 1999 Plan.  The fair value of each option grant is estimated on the date of grant using the Black-Scholes option-pricing model with the following weighted-average assumptions:    2017 2016 2015  Dividend Yield 2.03 % 2.88 % 2.93 %  Expected Life (years) 6.95 6.77 6.36  Expected Volatility 17.34 % 17.25 % 19.62 %  Risk-free Interest Rate 2.24 % 1.78 % 1.90 %  Weighted Average Fair Value $ 6.41 $ 3.05 $ 3.49   The Company used historical volatility calculated using daily closing prices for its common stock over periods that match the expected term of the option granted to estimate the expected volatility. The risk-free interest rate assumption was based upon U.S. Treasury yields appropriate for the expected term of the Company's stock options based upon the date of grant. The expected dividend yield was based upon the Company's recent history of paying dividends. The expected life was based upon the options’ expected vesting schedule and historical exercise patterns.  Stock options activity for 2017 was as follows:    Options Weighted Average Exercise Price Weighted Average Remaining Contractual Term (years) Aggregate Intrinsic Value (in thousands)  Balance, December 31, 2016 251,702 $ 18.66  Granted 24,990 39.50  Exercised (26,199) 17.66  Expired - -  Forfeited (9,273) 29.06  Balance, December 31, 2017 241,220 $ 20.53 5.18 $ 5,156   Exercisable, December 31, 2017 169,119 $ 16.79 3.89 $ 4,247   Future compensation cost expected to be expensed over the weighted average remaining contractual term for remaining outstanding options is $220 thousand.

The unrecognized compensation cost is scheduled to be recognized as follows:      (in thousands)  2018 $ 366  2019 240  2020 127  2021 23  During fiscal years 2017, 2016, and 2015, the following activity occurred under the Company’s plans:      2017 2016 2015  (in thousands)  Total intrinsic value of stock options exercised $ 567 $ 92 $ 409  Total fair value of restricted stock awards vested $ 645 $ 349 $ 287  Employee Stock Purchase Plan  The Company also maintains the Evans Bancorp, Inc. Employee Stock Purchase Plan (the “Purchase Plan”). As of December 31, 2017, there were 114,944 shares of common stock available to issue to full-time employees of the Company and its subsidiaries, nearly all of whom are eligible to participate. Under the terms of the Purchase Plan, employees can choose each year to have up to 15% of their annual base earnings withheld to purchase the Company’s common stock. Prior to 2017, the Company granted options on January 1 and July 1 of each year during the term of the Purchase Plan. The purchase price of the stock was 85% of the lower of its price on the grant date (January 1 and July 1) or the exercise date (June 30 and December 31). Starting in 2017, employees can purchase stock only on June 30 and December 31 each year during the term of the Purchase Plan for 85% of the price on the purchase date. The Company no longer grants employees the option to purchase the stock at the lower of the price at the beginning or end or the purchase periods. Under the Purchase Plan, the Company issued 7,610 , 10,596 , and 10,574 shares to employees in 2017, 2016, and 2015, respectively. In 2017, the compensation cost is calculated by the value of the 15% discount only. In 2015 and 2016, compensation cost was recognized for the fair value of the employees’ purchase rights, which was estimated using the Black-Scholes model with assumptions depicted in the following table.     2016 2015  Dividend Yield 2.93 % 3.01 %  Expected Life (years) 0.50 0.50  Expected Volatility 22.97 % 16.47 %  Risk-free Interest Rate 0.43 % 0.19 %  Weighted Average Fair Value $ 7.71 $ 6.92  The compensation cost that was charged against income for the Purchase Plan was $47 thousand, $75 thousand, and $71 thousand for 2017, 2016, and 2015, respectively.

Income Taxes [Abstract]
Income Taxes	13. INCOME TAXES  The components of the provision for income taxes were as follows:       2017 2016 2015  (in thousands)  Current federal tax expense $ 2,041 $ 1,990 $ 2,784  Current state tax expense 18 4 3  Total current tax expense 2,059 1,994 2,787   Deferred federal tax expense (benefit) $ 2,441 $ (405) $ 435  Deferred state tax expense 709 334 545  Total deferred tax expense (benefit) 3,150 (71) 980   Total income tax provision $ 5,209 $ 1,923 $ 3,767   The Company’s provision for income taxes differs from the amounts computed by applying the federal income tax statutory rates to income before income taxes. A reconciliation of the differences is as follows:       2017 2016 2015  Amount Percent Amount Percent Amount Percent  (in thousands)  Tax provision at statutory rate $ 5,334 34 % $ 3,466 34 % $ 3,947 34 %  Change in taxes resulting from:  Tax-exempt income (589) (4) (522) (5) (617) (5)  Historic tax credit (1,869) (12) (1,413) (14) - -  State taxes, net of federal benefit 455 2 236 2 362 3  Deferred tax asset remeasurement 2,074 13 - - - -  Other items, net (196) - 156 2 75 -  Income tax provision $ 5,209 33 % $ 1,923 19 % $ 3,767 32 %  In 2017, the Company recognized the impact of its investments in partnerships that incurred expenses related to the rehabilitation of certified historic structures located in New York State after the historic structures were placed in service. At the time a historic structure is placed in service, the Bank is eligible for a federal and New York State tax credit. As noted in Note 1, f or New York State, any new credit earned from rehabilitated historic properties placed in service on or after January 1, 2015 not used in the current tax year will be treated as a refund or overpayment of tax to be credited to the next year’s tax. Since the realization of the tax credit does not depend on the Bank’s generation of future taxable income or the Bank’s ongoing tax status or tax position, the refund is not considered an element of income tax accounting (ASC 740). In such cases, the Bank would not record the credit as a reduction of income tax expense; rather, the Bank includes the refundable New York State tax credit in non-interest income with a corresponding receivable recorded in other assets.  The following table presents the impact to the results of operations from the Bank’s historic tax credit activity for the years ended December 31, 2017 and 2016. There was no impact to the 2015 results of operations from historic rehabilitation tax credits.      2017 2016  (in thousands)   Loss on tax credit investment $ (3,997) $ (3,022)  Refundable state historic tax credit 2,843 2,117  Income tax benefit 1,869 1,413  Total HTC income $ 715 $ 508  At December 31, 2017 and 2016 the components of the net deferred tax asset were as follows:     2017 2016  (in thousands)  Deferred tax assets:  Pension and SERP plans $ 1,184 $ 2,094  Allowance for loan and lease losses 3,566 5,222  Non accrued interest 58 34  Deferred compensation 594 950  Litigation accrual 1 61  Loss on investment in tax credit 454 636  Stock options granted 137 169  Historic tax credit carryforward 518 786  Leases 109 157  Net unrealized losses on securities 364 224  Gross deferred tax assets $ 6,985 $ 10,333   Deferred tax liabilities:  Depreciation and amortization $ 1,428 $ 2,071  Prepaid expenses 479 476  Deferred dividend income 192 -  Mortgage servicing asset 151 200  Gross deferred tax liabilities $ 2,250 $ 2,747   Valuation allowance (285) (276)  Net deferred tax asset $ 4,450 $ 7,310   The net deferred tax asset at December 31, 2017 and 2016 is included in “other assets” in the Company’s consolidated balance sheets.  In assessing the ability of the Company to realize the benefit of the deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. Management considers the scheduled reversal of deferred tax liabilities, availability of operating loss carrybacks, projected future taxable income, and tax planning strategies in making this assessment. Based upon the level of historical taxable income, the opportunity for net operating loss carrybacks, and projections for future taxable income over the periods which deferred tax assets are deductible, management believes it is more likely than not the Company will generate sufficient taxable income to realize the benefits of these deductible differences at December 31, 2017, except for a valuation allowance of $171 thousand on the net deferred tax asset for the investment in a historic tax credits of $454 thousand and an allowance of $114 thousand on the net deferred tax asset for pension and SERP plans of $1.2 million. In assessing the need for a valuation allowance for the deferred tax assets for the investments in historic tax credits and for the SERP, the Company considered all positive and negative evidence in assessing whether the weight of available evidence supports the recognition of some or all of the deferred tax assets.  In regard to historic tax credit investments, because of the tax nature of the loss to be recognized when the investment is ultimately sold (which for tax purposes will give rise to a capital loss), the Company does not have any known capital gains in the future to be able to utilize the capital losses from these investments. Therefore, the Company’s assessment of the deferred tax asset warrants the need for a valuation allowance to be recognized on the deferred tax asset that it determined is more-likely-than-not to not be realized. The amount of remaining capital loss includes the projected capital basis after taking the tax credit, expected losses, and cash distributions.  In regard to the deferred tax asset related to the SERP, given the lump sum distribution election made by one of the Company’s executives, the Company expects it will pay that executive a SERP benefit of more than $1 million in a single fiscal year. Per Section 162(m) of the Internal Revenue Code, the amount exceeding $1 million is not deductible for income tax purposes. The Company therefore determined it is more-likely-than-not that the projected benefit obligation for the executive’s SERP benefit exceeding $1 million will not be deductible.  The state historic tax credit carryforward has an indefinite life with no expiration date in which to utilize the credit.  The Company did no t have any unrecognized tax benefits for the years ended December 31, 2017, 2016, and 2015.  There were no accrued penalties and interest at December 31, 2017 and 2016.  The Company is subject to routine audits of its tax returns by the Internal Revenue Service (“IRS”) and various state taxing authorities. During 2017, the Company concluded a NYS audit covering the years 2011-2014. The most recent IRS audit was completed in 2010 and covered the years 2006-2008. These audits concluded with no material adverse findings. The tax years 2015 - 2016 for NYS and 2014 - 2016 for the IRS remain subject to examination.  The most significant impact of the TCJA is on the Company’s marginal federal tax rate in 2018 and beyond, which will decrease from 35% to 21% . The change in the corporate tax rate resulted in a $2.0 million expense related to the remeasurement of the Company’s deferred tax asset as of December 31, 2017. The impact from the TCJA may differ from this estimate, due to, among other things, further refinement of the Company’s calculations, changes in interpretations and assumptions the Company has made, guidance that may be issued and actions the Company may take as a result of tax reform. Approximately $0.6 million of the $2.0 million expense is associated with deferred taxes related to unrealized gains on available-for-sale investment securities and the unamortized actuarial losses on the Pension Plan and the SERPs which were originally created through other comprehensive income. The Company reclassified the $0.6 million charge related to deferred tax expense for items originally recorded through OCI from OCI to retained earnings per ASU 2018-02, “Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income,” released in February 2018 and early adopted by the Company for the period ended December 31, 2017.  Other significant aspects of the TCJA that have a direct impact on the Company include:  · The Company is active in the historic rehabilitation tax credit (“HRTC”) market. Before TCJA, HRTC’s were allowed for 20% of qualified rehabilitation expenses (“QRE”) in the year the property is placed in service. For properties owned before December 31, 2017 in which construction is started by June 22, 2018 and completed by December 22, 2019, the old rules still apply. The Company has two remaining projects that fit these criteria. For all other projects, the HRTC for 20% of QRE will now be taken over a 5 year period rather than all in the first year. This delay in cash flows to investors will negatively impact the pricing on HRTC’s. The Company earned $0.7 million in net income on HRTC investments in 2017. The Company had historic tax credit investments valued at $1.2 million as of December 31, 2017.  · The TCJA limits the deductibility of executive compensation. The TCJA expands the definition of “covered employees” for purposes of Section 162(m) of the Internal Revenue Code to include the CFO, CEO, and the three most highly compensated officers for the tax year and designates covered employees as covered employees forever. Previously, if a covered employee retired, the individual would no longer be considered covered in retirement and therefore post-retirement payments to that individual would not be limited by Section 162(m). This change impacts the SERP for one of the Company’s executive officers, who has agreed to receive his benefit in a lump sum payment. The Company anticipates that this lump sum payment will exceed $1 million and the excess of the payment over $1 million will therefore be non-deductible. As of December 31, 2017, the executive’s projected benefit obligation was $1.4 million. As a result, the Company recorded a $114 thousand valuation allowance as an estimate of the non-deductible portion of the future benefit payment.

The Bank received the funds for the full loan amount, including the participating bank’s portion, but did not remit funds to the participating bank until the first business day of 2018. Therefore, the funds received on December 29, 2017 for the participating bank’s portion of the paid off loan was recorded as a liability as of December 31, 2017.

RELATED PARTY TRANSACTIONS  The Bank has entered into loan transactions with certain directors, executive officers, significant shareholders and their affiliates (related parties) in the ordinary course of its business. The aggregate outstanding principal balance of loans to such related parties on December 31, 2017 and 2016 was $3.3 million and $3.1 million, respectively. During 2017, there were $3.3 million of advances and new loans to such related parties, and repayments amounted to $3.1 million. Terms of these loans have prevailing market pricing that would be offered to similarly-situated non-affiliated third parties. Deposits from related parties were $2.4 million and $2.2 million as of December 31, 2017 and 2016, respectively.

Contingent Liabilities And Commitments [Abstract]
Contingent Liabilities And Commitments	16. CONTINGENT LIABILITIES AND COMMITMENTS  The Company’s consolidated financial statements do not reflect various commitments and contingent liabilities which arise in the normal course of business and which involve elements of credit risk, interest rate risk, and liquidity risk. These commitments and contingent liabilities are commitments to extend credit and standby letters of credit. A summary of the Bank’s commitments and contingent liabilities at December 31, 2017 and 2016 is as follows:     December 31, December 31,  2017 2016  (in thousands)   Commitments to extend credit $ 247,540 $ 217,581  Standby letters of credit 3,115 3,736  Total $ 250,655 $ 221,317  Commitments to extend credit and standby letters of credit all include exposure to some credit loss in the event of non-performance of the customer. The Bank’s credit policies and procedures for credit commitments and financial guarantees are the same as those for extensions of credit that are recorded on the Consolidated Balance Sheets. Because these instruments have fixed maturity dates, and because they may expire without being drawn upon, they do not necessarily represent cash requirements to the Bank. The Bank has no t incurred any losses on its commitments during the past three years and has no t recorded a reserve for its commitments.  The Company has entered into contracts with third parties, some of which include indemnification clauses. Examples of such contracts include contracts with third-party service providers, brokers and dealers, correspondent banks, and purchasers of residential mortgages. Additionally, the Company has bylaws, policies, and agreements under which it agrees to indemnify its officers and directors from liability for certain events or occurrences while the directors or officers are, or were, serving at the Company’s request in such capacities. The Company indemnifies its officers and directors to the fullest extent allowed by law. The maximum potential amount of future payments that the Company could be required to make under these indemnification provisions is unlimited, but would be affected by all relevant defenses to such claims, as well as directors’ and officers’ liability insurance maintained by the Company. Due to the nature of these indemnification provisions, it is not possible to quantify the aggregate exposure to the Company resulting from them.  Certain lending commitments for construction residential mortgage loans are considered derivative instruments under the guidelines of GAAP. The changes in the fair value of these commitments, due to interest rate risk, are not recorded on the consolidated balance sheets as the fair value of these derivatives is not considered to be material.  The Company leases certain offices, land and equipment under long-term operating leases. The aggregate minimum annual rental commitments under these leases total approximately $662 thousand in 2018; $650 thousand in 2019; $595 thousand in 2020; $538 thousand in 2021; $547 thousand in 2022, and $2.5 million thereafter. The rental expense under operating leases contained in the Company’s Consolidated Statements of Income included $651 thousand, $626 thousand, and $645 thousand, in 2017, 2016, and 2015, respectively.

Concentrations Of Credit	17. CONCENTRATIONS OF CREDIT  All of the Bank’s loans, commitments, and standby letters of credit have been granted to customers in the Bank’s primary market area, which is Western New York. Investments in state and municipal securities also involve governmental entities within the Bank’s primary market area. The concentrations of credit by type of loan are set forth in Note 3 to these Consolidated Financial Statements, "Loans and the Allowance for Loan Losses." The distribution of commitments to extend credit approximates the distribution of loans outstanding. Standby letters of credit were granted primarily to commercial borrowers. The Bank, as a matter of policy, does not extend credit to any single borrower or group in excess of 15% of capital.

Segment Information [Abstract]
Segment Information	18. SEGMENT INFORMATION  The Company is comprised of two primary business segments: banking activities and insurance agency activities. The operating segments are separately managed and their performance is evaluated based on net income. The banking business segment includes both commercial and consumer banking services, including a wide array of lending and depository services as well as offering non-deposit investment products, such as annuities and mutual funds. The insurance agency segment includes the activities of selling various premium-based insurance policies on a commission basis, including business and personal insurance, employee benefits, surety bonds, risk management, life, disability and long-term care coverage, as well as providing claims adjusting services to various insurance companies. All sources of segment specific revenues and expenses contributed to management’s definition of net income. Revenues from transactions between the two segments are not significant. The accounting policies of the segments are the same as those described in Note 1 of these “Notes to Consolidated Financial Statements.”  The following tables set forth information regarding these segments for the years ended December 31, 2017, 2016, and 2015.     2017  Banking Insurance Agency  Activities Activities Total  (in thousands)   Net interest income (expense) $ 42,119 $ (102) $ 42,017  Provision for loan losses 738 - 738  Net interest income (expense) after  provision for loan losses 41,381 (102) 41,279  Non-interest income 5,105 - 5,105  Insurance service and fees 416 7,482 7,898  Amortization expense - 113 113  Non-interest expense 32,610 5,871 38,481  Income before income taxes 14,292 1,396 15,688  Income tax provision 4,674 535 5,209  Net income $ 9,618 $ 861 $ 10,479     2016  Banking Insurance Agency  Activities Activities Total  (in thousands)   Net interest income (expense) $ 35,371 $ (123) $ 35,248  Provision for loan losses 1,209 - 1,209  Net interest income (expense) after  provision for loan losses 34,162 (123) 34,039  Non-interest income 4,733 - 4,733  Insurance service and fees 400 6,119 6,519  Non-interest expense 30,438 4,658 35,096  Income before income taxes 8,857 1,338 10,195  Income tax provision 1,408 515 1,923  Net income $ 7,449 $ 823 $ 8,272     2015  Banking Insurance Agency  Activities Activities Total  (in thousands)   Net interest income (expense) $ 31,921 $ (117) $ 31,804  Provision for loan losses 1,216 - 1,216  Net interest income (expense) after  provision for loan losses 30,705 (117) 30,588  Non-interest income 6,526 - 6,526  Insurance service and fees 672 6,522 7,194  Non-interest expense 28,103 4,595 32,698  Income before income taxes 9,800 1,810 11,610  Income tax provision (benefit) 3,071 696 3,767  Net income $ 6,729 $ 1,114 $ 7,843       December 31, December 31,  2017 2016  (in thousands)  Identifiable Assets, Net  Banking activities $ 1,285,173 $ 1,091,291  Insurance agency activities 10,460 9,418  Consolidated Total Assets $ 1,295,633 $ 1,100,709  

Fair Value Of Financial Instrum

Fair Value Of Financial Instruments [Abstract]
Fair Value Of Financial Instruments	19. FAIR VALUE OF FINANCIAL INSTRUMENTS  Fair value is defined in ASC Topic 820 “Fair Value Measurements and Disclosures” as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.  There are three levels of inputs to fair value measurements: · Level 1 inputs are quoted prices for identical instruments in active markets; · Level 2 inputs are inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly; and · Level 3 inputs are unobservable inputs.  Observable market data should be used when available.  FINANCIAL INSTRUMENTS MEASURED AT FAIR VALUE ON A RECURRING BASIS  The following table presents for each of the fair-value hierarchy levels as defined in this footnote, those financial instruments which are measured at fair value on a recurring basis at December 31, 2017 and 2016:      (in thousands) Level 1 Level 2 Level 3 Fair Value   December 31, 2017  Securities available-for-sale:  U.S. government agencies $ - $ 28,053 $ - $ 28,053  States and political subdivisions - 29,373 - 29,373  Mortgage-backed securities - 86,392 - 86,392  Mortgage servicing rights - - 586 586   December 31, 2016  Securities available-for-sale:  U.S. government agencies $ - $ 12,872 $ - $ 12,872  States and political subdivisions - 35,142 - 35,142  Mortgage-backed securities - 47,208 - 47,208  Mortgage servicing rights - - 527 527  Securities available for sale  Fair values for available for sale securities are determined using independent pricing services and market-participating brokers. The Company utilizes a third-party for these pricing services. The third-party utilizes evaluated pricing models that vary by asset class and incorporate available trade, bid and other market information for structured securities, cash flow and, when available, loan performance data. Because many fixed income securities do not trade on a daily basis, the third-party service provider’s evaluated pricing applications apply information as applicable through processes, such as benchmarking of like securities, sector groupings, and matrix pricing, to prepare evaluations. In addition, our third-party pricing service provider uses model processes, such as the Option Adjusted Spread model, to assess interest rate impact and develop prepayment scenarios. The models and the process take into account market convention. For each asset class, a team of evaluators gathers information from market sources and integrates relevant credit information, perceived market movements and sector news into the evaluated pricing applications and models. The third-party, at times, may determine that it does not have sufficient verifiable information to value a particular security. In these cases the Company will utilize valuations from another pricing service.  Management believes that it has a sufficient understanding of the third-party service’s valuation models, assumptions and inputs used in determining the fair value of securities to enable management to maintain an appropriate system of internal control. On a quarterly basis the Company reviews changes, as submitted by our third-party pricing service provider, in the market value of its securities portfolio. Individual changes in valuations are reviewed for consistency with general interest rate movements and any known credit concerns for specific securities. Additionally, on an annual basis the Company has its entire securities portfolio priced by a second pricing service to determine consistency with another market evaluator. If, on the Company’s review or in comparing with another servicer, a material difference between pricing evaluations were to exist, the Company may submit an inquiry to our third-party pricing service provider regarding the data used to value a particular security. If the Company determines it has market information that would support a different valuation than our third-party service provider’s evaluation it can submit a challenge for a change to that security’s valuation. There were no material differences in valuations noted in 2017 or 2016.  Securities available for sale are classified as Level 2 in the fair value hierarchy as the valuation provided by the third-party provider uses observable market data.  Mortgage servicing rights  Mortgage servicing rights (“MSRs”) do not trade in an active, open market with readily observable prices. Accordingly, the Company obtains the fair value of the MSRs using a third-party pricing provider. The provider determines the fair value by discounting projected net servicing cash flows of the remaining servicing portfolio. The valuation model used by the provider considers market loan prepayment predictions and other economic factors. The fair value of MSRs is mostly affected by changes in mortgage interest rates since rate changes cause the loan prepayment acceleration factors to increase or decrease. All assumptions are market driven. Management has a sufficient understanding of the third-party service’s valuation models, assumptions and inputs used in determining the fair value of MSRs to enable management to maintain an appropriate system of internal control. Mortgage servicing rights are classified within Level 3 of the fair value hierarchy as the valuation is model driven and primarily based on unobservable inputs.  The following table summarizes the changes in fair value for items measured at fair value (Level 3) on a recurring basis using significant unobservable inputs during the years ended December 31:      (in thousands) 2017 2016 2015  Mortgage servicing rights - January 1 $ 527 $ 557 $ 518  Losses included in earnings (48) (123) (93)  Additions from loan sales 107 93 132  Mortgage servicing rights - December 31 $ 586 $ 527 $ 557   Quantitative information about the significant unobservable inputs used in the fair value measurement of MSRs at the respective dates is as follows:      December 31, 2017 December 31, 2016  Servicing fees 0.25 % 0.25 %  Discount rate 9.50 % 9.52 %  Prepayment rate (CPR) 10.56 % 8.12 %  FINANCIAL INSTRUMENTS MEASURED AT FAIR VALUE ON A NONRECURRING BASIS  The Company is required, on a nonrecurring basis, to adjust the carrying value of certain assets or provide valuation allowances related to certain assets using fair value measurements. The following table presents for each of the fair-value hierarchy levels as defined in this footnote, those financial instruments which are measured at fair value on a nonrecurring basis at December 31, 2017 and 2016:        (in thousands) Level 1 Level 2 Level 3 Fair Value   December 31, 2017  Collateral dependent impaired loans $ - $ - $ 14,464 $ 14,464   December 31, 2016  Collateral dependent impaired loans $ - $ - $ 13,114 $ 13,114  Impaired loans  The Company evaluates and values impaired loans at the time the loan is identified as impaired, and the fair values of such loans are estimated using Level 3 inputs in the fair value hierarchy. Each loan’s collateral value has a unique appraisal and management’s discount of the value is based on factors unique to each impaired loan. The significant unobservable input in determining the fair value is management’s subjective discount on appraisals of the collateral securing the loan, which ranges from 10% - 50% . Fair value is estimated based on the value of the collateral securing these loans. Collateral may consist of real estate and/or business assets including equipment, inventory and/or accounts receivable and the value of these assets is determined based on appraisals by qualified licensed appraisers hired by the Company. Appraised and reported values may be discounted based on management’s historical knowledge, changes in market conditions from the time of valuation, estimated costs to sell, and/or management’s expertise and knowledge of the client and the client’s business.  The Company has an appraisal policy in which appraisals are obtained upon a commercial loan being downgraded on the Company internal loan rating scale to a 5 (special mention) or a 6 (substandard) depending on the amount of the loan, the type of loan, and the type of collateral. All impaired commercial loans are either graded a 6 or 7 on the internal loan rating scale, unless the commercial loan is impaired due to a troubled debt restructure and is now performing. For consumer loans, the Company obtains appraisals when a loan becomes 60 days past due or is determined to be impaired, whichever occurs first. Subsequent to the downgrade or reaching 60 days past due, if the loan remains outstanding and impaired for at least one year more, management may require another follow-up appraisal. Between receipts of updated appraisals, if necessary, management may perform an internal valuation based on any known changing conditions in the marketplace such as sales of similar properties, a change in the condition of the collateral, or feedback from local appraisers. Collateral dependent impaired loans had a gross value of $15.5 million, with a valuation allowance of $1.1 million, at December 31, 2017, compared to a gross value for collateral dependent impaired loans of $15.1 million, with a valuation allowance of $2.0 million, at December 31, 2016.  At December 31, 2017 and 2016, the estimated fair values of the Company’s financial instruments, including those that are not measured and reported at fair value on a recurring basis or nonrecurring basis, were as follows:      December 31, 2017 December 31, 2016  Carrying Fair Carrying Fair  Amount Value Amount Value  (in thousands) (in thousands)  Financial assets:  Level 1:  Cash and cash equivalents $ 21,330 $ 21,330 $ 13,084 $ 13,084  Level 2:  Available for sale securities 143,818 143,818 95,222 95,222  FHLB and FRB stock 6,779 6,779 3,731 3,731  Level 3:  Held to maturity securities 5,334 5,261 1,983 1,959  Loans, net 1,051,296 1,047,967 928,596 945,998  Mortgage servicing rights 586 586 527 527   Financial liabilities:  Level 1:  Demand deposits $ 219,664 $ 219,664 $ 201,741 $ 201,741  NOW deposits 109,378 109,378 88,632 88,632  Savings deposits 535,730 535,730 508,652 508,652  Level 2:  Securities sold under agreement to  repurchase 9,289 9,289 10,159 10,159  Other borrowed funds 88,250 88,132 28,200 28,152  Junior subordinated debentures 11,330 11,330 11,330 11,330  Level 3:  Time deposits 186,457 187,782 140,949 141,758   The following methods and assumptions were used to estimate the fair value of each class of financial instruments for which it is practicable to estimate that value.  Cash and Cash Equivalents  For these short-term instruments, the carrying amount is a reasonable estimate of fair value. “Cash and Cash Equivalents” includes cash and due from banks and interest-bearing deposits at other banks.  Securities Held to Maturity  The Company holds certain municipal bonds as held-to-maturity. These bonds are generally small in dollar amount and are issued only by certain local municipalities within the Company’s market area. The original terms are negotiated directly and on an individual basis consistent with our loan and credit guidelines. These bonds are not traded on the open market and management intends to hold the bonds to maturity. The fair value of held-to-maturity securities is estimated by discounting the future cash flows using the current rates at which similar agreements would be made with municipalities with similar credit ratings and for the same remaining maturities.  FHLB and FRB stock  The carrying value of FHLB and FRB stock, which are non-marketable equity investments, approximates fair value.  Loans Receivable  The fair value of fixed rate loans is estimated by discounting the future cash flows using the current rates at which similar loans would be made to borrowers with similar credit ratings and for the same remaining maturities, net of the appropriate portion of the allowance for loan losses. For variable rate loans, the carrying amount is a reasonable estimate of fair value. This fair value calculation is not necessarily indicative of the exit price, as defined in ASC Topic 820.  Deposits  The fair value of demand deposits, NOW accounts, muni-vest accounts and regular savings accounts is the amount payable on demand at the reporting date. The fair value of time deposits is estimated using the rates currently offered for deposits of similar remaining maturities.  Borrowed Funds and Securities Sold Under Agreement to Repurchase  The fair value of securities sold under agreement to repurchase approximates its carrying value. The fair value of other borrowed funds was estimated using a discounted cash flow analysis based on the Company’s current incremental borrowing rates for similar types of borrowing arrangements.  Junior Subordinated Debentures  There is no active market for the Company’s debentures and there have been no issuances of similar instruments in recent years. The Company looked at a market bond index to estimate a discount margin to value the debentures. The discount margin was very similar to the spread to LIBOR established at the issuance of the debentures. As a result, the Company determined that the fair value of the adjustable-rate debentures approximates their face amount.  Pension Plan Assets  Refer to Note 11 to these Consolidated Financial Statements, “Employee Benefits and Deferred Compensation Plans” for the fair value analysis of the Pension Plan assets.

Regulatory Matters [Abstract]
Regulatory Matters	20. REGULATORY MATTERS  Quantitative measures established by regulation to ensure capital adequacy require the Company to maintain minimum amounts and ratios (set forth in the table that follows) of Common Equity Tier I, Total Capital, and Tier I Capital (as defined in FRB regulations) to risk-weighted assets (as defined in FRB regulations), and of Tier I capital (as defined in FRB regulations) to average assets (as defined in FRB regulations). Management believes that as of December 31, 2017 and 2016, the Company and the Bank met all capital adequacy requirements to which they are subject.  The most recent notification from their regulators categorized the Company and the Bank as well capitalized under the regulatory framework for prompt corrective action. To be categorized as well capitalized, the Company and the Bank must maintain minimum Common Equity Tier I, total risk-based, Tier I risk-based, and Tier I leverage ratios as set forth in the table. There are no conditions or events since that notification that management believes have changed the Company’s or Bank’s category rating.  The Company’s and the Bank’s actual capital amounts and ratios were as follows:     December 31, 2017  (in thousands)  Company Bank Minimum for Capital Adequacy Purposes Minimum to be Well Capitalized Under Prompt Corrective Action Provisions  Amount Ratio Amount Ratio Amount Ratio Amount Ratio   Common Equity Tier I  (to Risk Weighted Assets) $ 125,283 11.72 % $ 122,421 11.48 % $ 48,102 4.5 % $ 69,481 6.5 %   Total Capital  (to Risk Weighted Assets) $ 138,654 12.97 % $ 135,764 12.73 % $ 85,515 8.0 % $ 106,894 10.0 %   Tier I Capital  (to Risk Weighted Assets) $ 125,283 11.72 % $ 122,421 11.48 % $ 64,136 6.0 % $ 85,515 8.0 %   Tier I Capital  (to Average Assets) $ 125,283 10.11 % $ 122,421 9.90 % $ 49,586 4.0 % $ 61,983 5.0 %   The Company is subject to the dividend restrictions imposed by the FRB and the OCC. Dividends are paid as declared by the Board of Directors. The Company may pay dividends only if it is solvent and would not be rendered insolvent by the dividend payment and only from unrestricted and unreserved earned surplus and under some circumstances capital surplus. The Bank’s dividend restrictions apply indirectly to the Company since cash available for dividend distribution will initially come from dividends paid to the Company by the Bank.  Dividends may be paid by the Bank only if it would not impair the Bank’s capital structure, if the Bank’s surplus is at least equal to its common capital and if the dividends declared in any year do not exceed the total of net profits in that year combined with undivided profits of the preceding two years less any required transfers to surplus, and if no losses have been sustained equal to or exceeding its undivided profits.  In addition, federal regulators have the ability to restrict dividend payments. If the Bank or the Company approaches well-capitalized or minimum capital adequacy levels, regulators could restrict or forbid dividend payments.

Organization And Summary Of Significant Accounting Policies [Abstract]
Organization And General	Organization and General  Evans Bancorp, Inc. (the “Company”) was organized as a New York business corporation and incorporated under the laws of the State of New York on October 28, 1988 for the purpose of becoming a bank holding company. Through August 2004, the Company was registered with the Federal Reserve Board (“FRB”) as a bank holding company under the Bank Holding Company Act of 1956, as amended. In August 2004, the Company filed for, and was approved as, a Financial Holding Company under the Bank Holding Company Act. The Company currently conducts its business through its two subsidiaries: Evans Bank, N.A. (the “Bank”), a nationally chartered bank, and its subsidiary, Evans National Holding Corp. (“ENHC”); and Evans National Financial Services, LLC (“ENFS”) and its subsidiary, The Evans Agency LLC (“TEA”). Unless the context otherwise requires, the term “Company” refers collectively to Evans Bancorp, Inc. and its subsidiaries. The Company conducts its business through its subsidiaries. It does not engage in any other substantial business. 
Regulatory Requirements	Regulatory Requirements  The Company is subject to the rules, regulations, and reporting requirements of various regulatory bodies, including the FRB, the Federal Deposit Insurance Corporation (“FDIC”), the Office of the Comptroller of the Currency (“OCC”), the New York State Department of Financial Services (“the NYSDFS”), and the SEC. 
Principles Of Consolidation	Principles of Consolidation  The consolidated financial statements include the accounts of the Company, the Bank, ENFS and their subsidiaries. All material inter-company accounts and transactions are eliminated in consolidation. 
Accounting Estimates	Accounting Estimates  Management has made a number of estimates and assumptions relating to the reporting of assets and liabilities and disclosure of contingent assets and liabilities in order to prepare these consolidated financial statements in conformity with U.S. generally accepted accounting principles. The estimates and assumptions that management deems to be critical involve our accounting policies relating to the determination of our allowance for loan losses and the valuation of goodwill. These estimates and assumptions are based on management’s best estimates and judgment and management evaluates them on an ongoing basis using historical experience and other factors, including the current economic environment, which management believes to be reasonable under the circumstances. We adjust our estimates and assumptions when facts and circumstances dictate. As future events cannot be determined with precision, actual results could differ significantly from our estimates. Changes in those estimates resulting from continuing changes in the economic environment will be reflected in the consolidated financial statements in periods as they occur. 
Cash And Cash Equivalents	Cash and Cash Equivalents  For purposes of reporting cash flows, cash and cash equivalents include cash and due from banks and interest-bearing deposits at banks. 
Securities	Securities  Securities which the Bank has the positive intent and ability to hold to maturity are classified as held to maturity and are stated at cost, adjusted for discounts and premiums that are recognized in interest income over the period to the earlier of the call date or maturity using the level yield method. These securities represent debt issuances of local municipalities in the Bank’s market area for which market prices are not readily available. Management periodically evaluates the financial condition of the municipalities for any indication that the Bank does not expect to recover the entire amortized cost basis of their bonds. Securities classified as available for sale are stated at fair value with unrealized gains and losses excluded from earnings and reported, net of deferred income taxes, in accumulated other comprehensive income or loss, a component of stockholders’ equity. Gains and losses on sales of securities are computed using the specific identification method.  Declines in the fair value of investment securities (with certain exceptions for debt securities noted below) that are deemed to be other-than-temporary are charged to earnings as a realized loss and a new cost basis for the securities is established. Declines in the fair value of debt securities below amortized cost are deemed to be other-than-temporary in circumstances where: (1) the Bank has the intent to sell a security; (2) it is more likely than not that the Bank will be required to sell the security before recovery of its amortized cost basis; or (3) the Bank does not expect to recover the entire amortized cost basis of the security. If the Bank intends to sell a security or if it is more likely than not that the Bank will be required to sell the security before recovery, an other-than-temporary impairment write-down is recognized in earnings equal to the difference between the security’s amortized cost basis and its fair value. If the Bank does not intend to sell the security or it is not more likely than not that it will be required to sell the security before recovery, the other-than-temporary impairment write-down is separated into an amount representing credit loss, which is recognized in earnings, and an amount related to all other factors, which is recognized in other comprehensive income. There were no charges associated with other-than-temporary impairment declines in fair value of securities in 2017, 2016, or 2015.  The Bank does not engage in securities trading activities. 
Loans	Loans  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 unamortized deferred fees or costs. Interest income is accrued on the unpaid principal balance and is recognized using the interest method. Loan origination fees, net of certain direct origination costs, are deferred and recognized as an adjustment of the related loan yield using the effective yield method of accounting for amortizing loans and straight line over an estimated life for lines of credit.  Loans become past due when the payment date has been missed. If payment has not been received within 30 days, then the loan is delinquent. Delinquent loans are placed into three categories; 30-59 days past due, 60-89 days past due, or 90+ days past due. Loans 90 or more days past due are considered non-performing.  The accrual of interest on loans is discontinued at the time the loan is 90 days delinquent, unless the credit is well secured and in process of collection. If the credit is not well secured and in the process of collection, the loan is placed on non-accrual status and is subject to charge-off if collection of principal or interest is considered doubtful. A loan can also be placed on nonaccrual before it is 90 days delinquent if management determines that it is probable that the Bank will be unable to collect principal or interest due according to the contractual terms of the loan.  All interest due but not collected for loans that are placed on non-accrual status or charged off is reversed against interest income. The interest on these loans is accounted for on the cost-recovery method, until it again qualifies for an accrual basis. Any cash receipts on non-accrual loans reduce the carrying value of the loans. Loans are returned to accrual status when all principal and interest amounts contractually due are brought current, the adverse circumstances which resulted in the delinquent payment status are resolved, and payments are made in a timely manner for a period of time sufficient to reasonably assure their future dependability.  The Bank considers a loan impaired when, based on current information and events, it is probable that it will be unable to collect principal or interest due according to the contractual terms of the loan. These loans are individually assessed for any impairment. Loan impairment is measured based on the present value of expected cash flows discounted at the loan’s effective interest rate or, as a practical expedient, at the loan’s observable market price or the fair value of the collateral, less costs to sell, if the loan is collateral dependent. Appraised and reported values may be discounted based on management’s historical knowledge, changes in market conditions from the time of valuation, estimated costs to sell, and/or management’s expertise and knowledge of the client and the client’s business. The Company has an appraisal policy in which appraisals are obtained upon a loan being downgraded on the Company’s internal loan rating scale to a 5 (special mention) or a 6 (substandard) depending on the amount of the loan, the type of loan and the type of collateral. All impaired nonaccrual loans are either graded a 6 or 7 on the internal loan rating scale. Subsequent to the downgrade, if the loan remains outstanding and impaired for at least one year more, management may require another follow-up appraisal. Between receipts of updated appraisals, if necessary, management may perform an internal valuation based on any known changing conditions in the marketplace such as sales of similar properties, a change in the condition of the collateral, or feedback from local appraisers. The Bank monitors the credit risk in its loan portfolio by reviewing certain credit quality indicators (“CQI”). The primary CQI for its commercial mortgage and commercial and industrial (“C&I”) portfolios is the individual loan’s credit risk rating. The following list provides a description of the credit risk ratings that are used internally by the Bank when assessing the adequacy of its allowance for loan losses:  · 1-3-Pass: Risk Rated 1-3 loans are loans with a slight risk of loss. The loan is secured by collateral of sufficient value to cover the loan by an acceptable margin. The financial statements of the company demonstrate sufficient net worth and repayment ability. The company has established an acceptable credit history with the bank and typically has a proven track record of performance. Management is experienced, and has an at least average ability to manage the company. The industry has an average or less than average susceptibility to wide fluctuations in business cycles. · 4-Watch: Although generally acceptable, a higher degree of risk is evident in these watch credits. Obligor assessment factors may have elements which reflect marginally acceptable conditions warranting more careful review and analysis and monitoring.  The obligor’s balance sheet reflects generally acceptable asset quality with some elements weak or marginally acceptable. Liquidity may be somewhat strained, but is at an acceptable level to support operations. Obligor may be fully leveraged with ratios higher than industry averages. High leverage is negatively impacting the company, leaving it vulnerable to adverse change. Inconsistent or declining capability to service existing debt requirements evidenced by debt service coverage temporarily below or near acceptable level. The margin of collateral may be adequate, but declining or fluctuating in value. Company management may be unproven, but capable. Rapid expansion or acquisition may increase leverage or reduce cash flow.  Negative industry conditions or weaker management could also be characteristic. Proper consideration should be given to companies in a high growth phase or in development business segments that may not have achieved sustainable earnings.  Obligors demonstrate sufficient financial flexibility to react to and positively address the root cause of the adverse financial trends without significant deviations from their current business strategy. The rating is also used for borrowers that have made significant progress in resolving their financial weaknesses.  · 5-O.A.E.M. (Other Assets Especially Mentioned): Special Mention (“SM”) – A special mention asset has potential weaknesses that warrant management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the asset or in the institution’s credit position at some future date.  SM assets have potential weaknesses that may, if not checked or corrected, weaken the asset or inadequately protect the institution’s position at some future date. These assets pose elevated risk, but their weakness does not yet justify a substandard classification. Borrowers may be experiencing adverse operating trends (declining revenues or margins) or an ill proportioned balance sheet (e.g. increasing inventory without an increase in sales, high leverage, tight liquidity).  Adverse economic or market conditions, such as interest rate increases or the entry of a new competitor, may also support a special mention rating. Nonfinancial reasons for rating a credit exposure special mention include management problems, pending litigation, an ineffective loan agreement or other material structural weakness, and any other significant deviation from prudent lending practices.  The SM rating is designed to identify a specific level of risk and concern about asset quality. Although an SM asset has a higher probability of default than a pass asset, its default is not imminent.  · 6-Substandard: A substandard asset is inadequately protected by the current sound worth and paying capacity of the obligor or of the collateral pledged, if any. Assets so classified must have a well-defined weakness, or weaknesses, that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the Bank will sustain some loss if the deficiencies are not corrected.  Substandard assets have a high probability of payment default, or they have other well-defined weaknesses. They require more intensive supervision by Bank management.  Substandard assets are generally characterized by current or expected unprofitable operations, inadequate debt service coverage, inadequate liquidity, or marginal capitalization. Repayment may depend on collateral or other credit risk subsidies. For some substandard assets, the likelihood of full collection of interest and principal may be in doubt; such assets should be placed on non-accrual. Although substandard assets in the aggregate will have distinct potential for loss, an individual asset’s loss potential does not have to be distinct for the asset to be rated substandard. These loans are periodically reviewed and tested for impairment.  · 7-Doubtful: An asset classified doubtful has all the weaknesses inherent in one classified substandard with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable.  A doubtful asset has a high probability of total or substantial loss, but because of specific pending events that may strengthen the asset, its classification of loss is deferred.  Doubtful borrowers are usually in default, lack adequate liquidity or capital, and lack the resources necessary to remain an operating entity. Pending events can include mergers, acquisitions, liquidations, capital injections, the perfection of liens on additional collateral, the valuation of collateral, and refinancing.  Generally, pending events should be resolved within a relatively short period and the ratings will be adjusted based on the new information. Because of high probability of loss, non-accrual accounting treatment is required for doubtful assets.  · 8-Loss: Assets classified loss are considered uncollectable and of such little value that their continuance as bankable assets is not warranted. This classification does not mean that the assets have absolutely no recovery or salvage value, but rather that it is not practical or desirable to defer writing off this basically worthless asset even though partial recovery may be affected in the future.  With loss assets, the underlying borrowers are often in bankruptcy, have formally suspended debt repayments, or have otherwise ceased normal business operations. Once an asset is classified loss, there is little prospect of collecting either its principal or interest. When access to collateral, rather than the value of the collateral, is a problem, a less severe classification may be appropriate. Losses are to be recorded in the period an obligation becomes uncollectible.  The Company’s consumer loans, including residential mortgages and home equities, are not individually risk rated or reviewed in the Company’s loan review process. Consumers are not required to provide the Company with updated financial information as is a commercial customer. Consumer loans also carry smaller balances. Given the lack of updated information since the initial underwriting of the loan and small size of individual loans, the Company does not have credit risk ratings for consumer loans and instead uses delinquency status as the credit quality indicator for consumer loans. However, once a consumer loan is identified as impaired, it is individually evaluated for impairment. 
Allowance For Loan Losses	Allowance for Loan Losses  The provision for loan losses represents the amount charged against the Bank’s earnings to maintain an allowance for loan losses inherent in the portfolio based on management’s evaluation of the loan portfolio at the balance sheet date. Factors considered by the Bank’s management in establishing the allowance include: the collectability of individual loans, current loan concentrations, charge-off history, loss emergence period, delinquent loan percentages, the fair value of the collateral, input from regulatory agencies, and general economic conditions.  On a quarterly basis, management of the Bank meets to review and determine the adequacy of the allowance for loan losses. In making this determination, the Bank’s management analyzes the ultimate collectability of the loans in its portfolio by incorporating feedback provided by the Bank’s internal loan staff, an independent internal loan review function and information provided by examinations performed by regulatory agencies.  The analysis of the allowance for loan losses is composed of two components: specific credit allocation and general portfolio allocation. The specific credit allocation includes a detailed review of each impaired loan and allocation is made based on this analysis. Factors may include the appraisal value of the collateral, the age of the appraisal, the type of collateral, the performance of the loan to date, the performance of the borrower’s business based on financial statements, and legal judgments involving the borrower. The general portfolio allocation consists of an assigned reserve percentage based on the historical loss experience, the loss emergence period, and other qualitative factors of the loan category.  The general portfolio allocation is segmented into homogeneous pools of loans with similar characteristics. Separate pools of loans include loans pooled by loan grade and by portfolio segment. An average historical loss rate over the past six years multiplied by the loss emergence period factor is applied against these loans.  For both the criticized and non-criticized loan pools in the general portfolio allocation, additional qualitative factors are applied. The qualitative factors applied to the general portfolio allocation reflect management’s evaluation of various conditions. The conditions evaluated include the following: levels and trends in delinquencies, non-accruals, and criticized loans; trends in volume and terms of loans; effects of any changes in lending policies and credit quality underwriting standards; experience, ability, and depth of management; national and economic trends and conditions; changes in the quality of the loan review system; concentrations of credit risk; changes in collateral value; and large loan risk. The total possible qualitative allocation is determined by comparing peer bank historical charge-off rates to the Bank’s historical charge-off rate. The actual qualitative allocation is determined by qualitative factor by loan type based on metrics that management believes are appropriate indicators of whether the Bank is in a low, moderate, or high risk range relative to historical experience for each qualitative factor. 
Foreclosed Real Estate	Foreclosed Real Estate  Foreclosed real estate is initially recorded at the lower of carrying or fair value (net of costs of disposal) at the date of foreclosure. Costs relating to development and improvement of property are capitalized, whereas costs relating to the holding of property are expensed. Assessments are periodically performed by management, and an allowance for losses is established through a charge to operations if the carrying value of a property exceeds fair value. The Company held no foreclosed real estate at December 31, 2017 or December 31, 2016.   
Insurance Commissions And Fees	Insurance Commissions and Fees  Commission revenue is recognized as of the effective date of the insurance policy. The Company also receives contingent commissions from insurance companies which are based on the overall profitability of their relationship based primarily on the loss experience of the insurance placed by the Company. Contingent commissions from insurance companies are recognized when determinable. 
Goodwill And Other Intangible Assets	  Goodwill and Other Intangible Assets  The Company accounts for goodwill and other intangible assets in accordance with ASC Topic 350, "Intangibles – Goodwill and Other." The Company records the excess of the cost of acquired entities over the fair value of identifiable tangible and intangible assets acquired, less liabilities assumed, as goodwill. The Company amortizes acquired intangible assets with definite useful economic lives over their useful economic lives utilizing the straight-line method. On a periodic basis, management assesses whether events or changes in circumstances indicate that the carrying amounts of the intangible assets may be impaired. The Company does not amortize goodwill and any acquired intangible asset with an indefinite useful economic life, but reviews them for impairment at a reporting unit level on an annual basis, or when events or changes in circumstances indicate that the carrying amounts may be impaired. A reporting unit is defined as any distinct, separately identifiable component of one of our operating segments for which complete, discrete financial information is available and reviewed regularly by the segment’s management. The only reporting unit with goodwill as of December 31, 2017 was the insurance agency activities reporting unit.  The fair value of the insurance agency activities reporting unit is measured annually as of December 31st utilizing the average of a discounted cash flow model and a market value based on a multiple to earnings before interest, taxes, depreciation, and amortization (“EBITDA”) for similar companies. The calculated value of the insurance agency reporting unit was in excess of the carrying amount at December 31, 2017. The Company has performed the required goodwill impairment tests and has determined that goodwill was not impaired as of December 31, 2017. 
Bank-Owned Life Insurance	Bank-Owned Life Insurance  The Bank has purchased insurance on the lives of Company directors and certain members of the Bank's and TEA's management. The policies accumulate asset values to meet future liabilities, including the payment of employee benefits, such as retirement benefits. Increases in the cash surrender value are recorded as other income in the Company’s Consolidated Statements of Income. 
Properties And Equipment	 Properties and Equipment  Properties and equipment are stated at cost less accumulated depreciation. Depreciation is computed using the straight-line method over the estimated useful lives of the assets, which range from 3 to 39 years. Impairment losses on properties and equipment are realized if the carrying amount is not recoverable from its undiscounted cash flows and exceeds its fair value in accordance with ASC Topic 360, “Property, Plant, and Equipment.” 
Income Taxes	Income Taxes  Deferred tax assets and liabilities are recognized for the future tax effects attributable to differences between the financial statement value of existing assets and liabilities and their respective tax bases and carryforwards. Deferred tax assets and liabilities are reflected at currently enacted income tax rates applicable to the periods in which the deferred tax assets or liabilities are expected to be realized or settled. As changes in tax laws or rates are enacted, deferred tax assets and liabilities are adjusted through income tax expense.  The Bank has invested in partnerships that incur expenses related to the rehabilitation of a certified historic structure located in New York State. At the time the historic structure is placed in service, the Bank is eligible for a federal and New York State tax credit. At the same time, the Bank evaluates its investment, which is valued at the present value of the expected cash flows from its partnership interest. If the investment is determined to be impaired, the Bank will record that impairment loss on its income statement in non-interest income. The federal tax credit impact is included in the Company’s estimated effective tax rate calculation and recorded in income tax expense. For New York State, any new credit earned from rehabilitated historic properties placed in service on or after January 1, 2015 not used in the current tax year will be treated as a refund or overpayment of tax to be credited to the next year’s tax. Since the realization of the tax credit does not depend on the Bank’s generation of future taxable income or the Bank’s ongoing tax status or tax position, the refund is not considered an element of income tax accounting (ASC 740). In such cases, the Bank would not record the credit as a reduction of income tax expense; rather, the Bank includes the refundable New York State tax credit in non-interest income with a corresponding receivable recorded in other assets.  The Tax Cuts and Jobs Act (“TCJA”), which represents one of the most significant overhauls to the United States federal tax code since 1986, was signed into law on December 22, 2017. The TCJA reduces the Company’s marginal federal income tax rate from 35% to 21%, but also reduces the benefit of historic tax credit investments. The impact of the TCJA on the Company is detailed in Note 13 to the Consolidated Financial Statements. In addition to the decrease in the marginal federal income tax rate, there are many other provisions in the TCJA that affect corporations generally but are not expected to impact the Company including limits on the deductibility of FDIC insurance premium for banks with more than $10 billion in assets, various provisions related to companies with international operations, and limitations on the deductibility of interest expense.
Earnings Per Share	 Earnings Per Share  Earnings per common share is determined by dividing net income by the weighted average number of shares outstanding during the period. Diluted earnings per common share is based on increasing the weighted-average number of shares of common stock by the number of shares of common stock that would be issued assuming the exercise of stock options. Such adjustments to weighted-average number of shares of common stock outstanding are made only when such adjustments are expected to dilute earnings per common share. There were 122,434 , 76,632 , and 72,320 potentially dilutive shares of common stock included in calculating diluted earnings per share for the years ended December 31, 2017, 2016, and 2015, respectively. Potential common shares that would have the effect of increasing diluted earnings per share are considered to be anti-dilutive. In accordance with ASC Topic 260, "Earnings Per Share," these shares were not included in calculating diluted earnings per share. There were no anti-dilutive shares at each of December 31, 2017 and 2016. As of December 31, 2015, there were 36 thousand shares that were not included in calculating diluted earnings per share because their effect was anti-dilutive. 
Treasury Stock	Treasury Stock  Repurchases of shares of Evans Bancorp, Inc. stock are recorded at cost as a reduction of shareholders’ equity. Reissuances of shares of treasury stock are recorded at market value.
Comprehensive Income	Comprehensive Income  Comprehensive income includes both net income and other comprehensive income, including the change in unrealized gains and losses on securities available for sale, and the change in the liability related to pension costs, net of tax. 
Employee Benefits	Employee Benefits  The Bank maintains a non-contributory, qualified, defined benefit pension plan (the “Pension Plan”) that covered substantially all employees before it was frozen on January 31, 2008. All benefits eligible participants had accrued in the Pension Plan until the freeze date have been retained. Employees have not accrued additional benefits in the Pension Plan from that date. The actuarially determined pension benefit in the form of a life annuity is based on the employee’s combined years of service, age and compensation. The Bank’s policy is to fund the minimum amount required by government regulations. Employees are eligible to receive these benefits at normal retirement age.  The Bank maintains a defined contribution 401(k) plan and accrues contributions due under this plan as earned by employees. In addition, the Bank maintains a non-qualified Supplemental Executive Retirement Plan for certain members of senior management, a non-qualified Deferred Compensation Plan for directors and certain members of management, and a non-qualified Executive Incentive Retirement Plan for certain members of management, as described more fully in Note 11 to these Consolidated Financial Statements, “Employee Benefits and Deferred Compensation Plans.”
Stock-Based Compensation	 Stock-based Compensation  Stock-based compensation expense is recognized over the vesting period of the stock-based grant based on the estimated grant date value of the stock-based compensation that is expected to vest. Information on the determination of the estimated value of stock-based awards used to calculate stock-based compensation expense is included in Note 12 to these Consolidated Financial Statements, “Stock-Based Compensation.”  ASU 2016-09, Improvements to Employee Share-Based Payment Accounting , was adopted effective January 1, 2017. This ASU is part of the FASB’s Simplification Initiative. The areas for simplification in this Update involve several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. Some of the areas of simplification apply only to nonpublic entities. One part of this ASU that impacted the Company was the elimination of the concept of a tax windfall pool. Previously, an entity determined for each award whether the difference between the deduction for tax purposes and the compensation cost recognized for financial reporting purposes resulted in either an excess benefit or a tax deficiency. Excess tax benefits were recognized in additional paid-in-capital; tax deficiencies were recognized either as an offset to accumulated excess tax benefits, if any, or in the income statement. Excess tax benefits were not recognized until the deduction reduced taxes payable. Under the new standard, all excess tax benefits and tax deficiencies are recognized as income tax expense or benefit in the income statement in the period in which they are incurred. The impact on the Company was a tax benefit of $0.2 million for the year ended December 31, 2017.  In addition, the Company made the accounting policy election effective January 1, 2017 to account for forfeitures of stock awards when they occur rather than estimating the number of awards that are expected to vest. When stock awards are granted, the Company assumes that the service condition will be achieved when determining the initial amount of compensation cost recognized. This election has not had a material impact on the Company’s financial statements. 
Loss Contingencies	Loss Contingencies  Loss contingencies, including claims and legal actions arising in the ordinary course of business, are recorded as liabilities when the likelihood of loss is probable and an amount or range of loss can be reasonably estimated. 
Financial Instruments With Off-Balance Sheet Risk	Financial Instruments with Off-Balance Sheet Risk  In the ordinary course of business, the Bank has entered into off-balance sheet financial arrangements consisting of commitments to extend credit and standby letters of credit. The Bank provides guarantees in the form of standby letters of credit, which represent an irrevocable obligation to make payments to a third party if the borrower defaults on its obligation under a borrowing or other contractual arrangement with the third party. The Bank could potentially be required to make payments to the extent of the amount guaranteed by the standby letters of credit based on the terms of the agreement. The maximum potential amount of future payments under standby letters of credit was $3.1 million and $3.7 million as of December 31, 2017 and 2016, respectively. There were no liabilities recorded on the Consolidated Balance Sheets related to standby letters of credit as of December 31, 2017 and 2016, respectively, reflecting management’s assessment of the value of the guarantee given the lack of historical activity and the likelihood of current customers to draw on the letters of credit. The Bank has not incurred any losses on its commitments during the past three years and has not recorded a reserve for its commitments. 
Advertising Costs	Advertising costs  Advertising costs are expensed as incurred.
Recent Accounting Pronouncements And Developments	RECENT ACCOUNTING PRONOUNCEMENTS AND DEVELOPMENTS  Below are accounting policies recently issued or proposed but not yet required to be adopted as of December 31, 2017. To the extent management believes the adoption of new accounting standards materially affects the Company’s financial condition, results of operations, or liquidity, the impacts are discussed below.  Accounting Standards Update (“ASU”) 2014-09, Revenue from Contracts with Customers. The objective of this ASU is to require entities to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. This ASU modifies the guidance used to recognize revenue from contracts with customers for transfers of goods or services and transfers of nonfinancial assets, unless those contracts are within the scope of other guidance. The ASU also requires new qualitative and quantitative disclosures, including disaggregation of revenues and descriptions of performance obligations. The Company adopted the guidance on January 1, 2018 using the modified retrospective method with a cumulative-effect adjustment to opening retained earnings. Because the guidance does not apply to revenue associated with financial instruments, including loans and securities that are accounted for under other U.S. GAAP, the new revenue recognition standard did not have a material impact on the Company’s consolidated financial statements. The Company’s implementation efforts included the identification of revenue within the scope of the guidance, as well as the evaluation of revenue contracts. The Company did identify one revenue source, variable profit-sharing revenue for TEA, which will be accounted for differently in 2018 and beyond. Profit-sharing revenue is variable consideration that TEA earns based on the loss ratio of its customers at insurance companies. TEA typically receives the cash consideration the following year, mostly in the first quarter, for the profit-sharing revenue earned in the previous year. Prior to January 1, 2018, the Company recognized profit-sharing revenue when the cash was received. After January 1, 2018, the Company will estimate this variable consideration based on past performance and loss experience known during the year and make subsequent adjustments to revenue when the uncertainty associated with the variable revenue is resolved. The Company recorded a cumulative-effect adjustment to retained earnings of $0.4 million as of January 1, 2018 related to TEA’s variable profit-sharing revenue.  ASU 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities. The main objective of this ASU is to enhance the reporting model for financial instruments to provide users of financial statements with more decision-useful information. The amendments in this ASU are effective for annual reporting periods beginning after December 15, 2017, including interim periods within those fiscal years. The ASU will not impact results of operations or the financial position of the Company, but will impact its fair value disclosures in the notes to the financial statements.  ASU 2016-02, Leases . The objective of this ASU is to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements to meet that objective. Under this new guidance, a lessee should recognize in the statement of financial position a liability to make lease payments and a right-of-use asset representing its right to use the underlying asset for the lease term. The recognition, measurement, and presentation of expenses and cash flows arising from a lease by a lessee have not significantly changed from previous GAAP. Information about the Company’s operating lease obligations is disclosed in Note 16 to the Company’s Consolidated Financial Statements included in Item 8 of this Annual Report on Form 10-K. The amendments in this ASU are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. The Company is currently evaluating the impact of the standard on its financial reporting.  ASU 2016-13, Financial Instruments – Credit Losses: Measurement of Credit Losses on Financial Instruments . Current GAAP requires an “incurred loss” methodology for recognizing credit losses that delays recognition until it is probable a loss has been incurred. Both financial institutions and users of their financial statements expressed concern that current GAAP restricts the ability to record credit losses that are expected, but do not yet meet the “probable” threshold. The main objective of this ASU (commonly known as the Current Expected Credit Loss Impairment Model, or CECL, in the industry) is to provide financial statement users with more decision-useful information about the expected credit losses on financial instruments and other commitments to extend credit held by a reporting entity at each reporting date. To achieve this objective, the amendments in CECL replace the incurred loss impairment methodology in current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. The amendments in CECL are effective for the Company for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. The FASB expects that an entity will be able to leverage its current systems and methods for recording the allowance for credit losses. However, many financial institutions, particularly community banks similar in size to the Company and industry groups like the American Bankers Association, have expressed concern about the impact of CECL. The life of loan loss concept presents complexities that can decrease capital, and add both volatility to the allowance for loan losses (“ALLL”) estimates and additional costs. CECL may increase the ALLL, though many factors will determine the impact for each bank. Changes in expectations of future economic conditions play a large role in CECL and can significantly affect the credit loss estimate. A challenge for the Company could be the operational impact. Costly new systems and processes to track loan performance may need to be purchased or developed. Significant procedural challenges may be faced both in implementation and on an ongoing basis. The total impact of CECL to the Company’s financial statements is unknown but may be material. Implementation of CECL will be a significant project for the Company through the projected implementation date of January 1, 2020.  ASU 2017-04, Simplifying the Test for Goodwill Impairment. The objective of this ASU is to simplify how an entity is required to test goodwill 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. Under the amendments in this ASU, an entity will perform its annual goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity would recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value. The amendments in this ASU are effective for annual reporting periods beginning after December 15, 2019, including interim periods within those fiscal years. The Company does not expect the standard to have a material impact on the Company’s financial reporting.  ASU 2017-08, Premium Amortization on Purchased Callable Debt Securities . The objective of this ASU is to amend the amortization period for certain purchased callable debt securities held at a premium. The FASB is shortening the amortization period for the premium to the earliest call date. Under current GAAP, entities generally amortize the premium as an adjustment of yield over the contractual life of the investment. Current GAAP excludes certain callable debt securities from consideration of early repayment of principal even if the holder is certain that the call will be exercised. As a result, upon the exercise of a call on a callable debt security held at a premium, the unamortized premium is recorded as a loss in earnings. The amendments do no not require an accounting change for securities held at a discount; the discount continues to be amortized to maturity. The amendments in this ASU are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. The Company does hold callable debt securities that were purchased at a premium and is currently evaluating the impact of the standard on its financial reporting.  ASU 2018-02, Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. This ASU allows a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the TCJA. Consequently, the ASU eliminates the stranded tax effects resulting from the TCJA. This ASU was issued in response to concern expressed by stakeholders about the guidance in current GAAP that requires deferred tax liabilities and assets to be adjusted for the effect of a change in tax laws or rates with the effect included in income from continuing operations in the reporting period that includes the enactment date. That guidance is applicable even in situations in which the related income tax effects of items in accumulated other comprehensive income were originally recorded in other comprehensive income (rather than in income from continuing operations). The ASU is effective for fiscal years beginning after December 15, 2018 and interim periods within those fiscal years. Early adoption is permitted for reporting periods for which financial statements have not yet been issued or been made available for issuance. Given that the ASU was issued before the issuance of the Company’s Consolidated Financial Statements in this Form 10-K, the Company early adopted the ASU and recorded a reclassification from accumulated other comprehensive income to retained earnings as of December 31, 2017 of $0.6 million.
