Organization and Nature of Operations [Abstract]
Organization and Nature of Operations	N ote 1 - Organization and Nature of Operations  Organizational Structure  Lake Shore Bancorp, Inc. (the “Company,” “us,” “our,” or “we”) and the parent mutual holding company, Lake Shore, MHC (the “MHC”) were formed on April 3, 2006 to serve as the stock holding companies for Lake Shore Savings Bank (the “Bank”) as part of the Bank’s conversion and reorganization from a New York State chartered mutual savings and loan association to the federal mutual holding company form of organization.  The MHC, whose activity is not included in these consolidated financial statements, held 3,636,875 shares, or 60.6 % of the Company’s outstanding common stock as of December 31, 2018.  Charter  Lake Shore Bancorp, Inc. and the parent mutual holding company, Lake Shore, MHC are federally chartered and regulated by the Federal Reserve Board. Lake Shore Savings Bank, subsidiary of Lake Shore Bancorp, Inc., is a federally chartered savings bank and regulated by the Office of the Comptroller of the Currency (the “OCC”).  Regulations of the Board of Governors of the Federal Reserve System (the “Federal Reserve”) prohibit the waiver of dividends by the MHC unless the waiver has been approved by its members, consisting of depositors of the Bank. The MHC held a special meeting on February 6, 2019 of its members to vote on a proposal to authorize the MHC to waive its right to receive dividends aggregating up to $ 0. 48 per share that may be declared by the Company in the twelve months subsequent to the approval of the proposal by members. At the special meeting, a majority of the eligible member votes of the MHC approved the waiver of the receipt of dividends on shares owned by the MHC. Lake Shore, MHC submitted the results of this vote along with other information to the Federal Reserve for final approval of the dividend waiver. As of March 7, 2019, Lake Shore, MHC received notice of the non-objection of the Federal Reserve Board to waive its right to receive dividends paid by the Company during the twelve months ending February 6, 2020. In prior periods, the MHC elected to waive its right to receive cash dividends upon receipt of the non-objection of the Federal Reserve Board. The waiving of dividends by the MHC will increase Company resources available for stock repurchases, payment of dividends to minority stockholders, and investments. As of December 31, 2018, the MHC elected to waive approximately $ 10.8 million on a cumulative basis. The dividends waived by the MHC are considered a restriction on the retained earnings of the Company.  Nature of Business  The Company’s primary business is the ownership and operation of its subsidiary, the Bank. The Bank is engaged primarily in the business of retail banking through eleven branch offices located in Erie and Chautauqua Counties of New York State. Its primary deposit products are checking, savings and term certificate accounts and its primary lending products are residential mortgages and commercial real estate loans.

Summary of Significant Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Note 2 - Summary of Significant Accounting Policies  Basis of Presentation The consolidated financial statements include the accounts of the Company and the Bank. All material inter-company accounts and transactions have been eliminated. The accompanying consolidated financial statements have been prepared in conformity with generally accepted accounting principles in the United States of America (“GAAP”).  Use of Estimates To prepare these consolidated financial statements in conformity with GAAP, management of the Company made a number of estimates and assumptions relating to the reporting of assets and liabilities, the reporting of revenue and expenses and notes to the consolidated financial statements. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for loan losses, securities valuation estimates, evaluation of impairment of securities, income taxes and deferred compensation liabilities. Cash and Cash Equivalents Cash and cash equivalents include cash on hand, amounts due from banks, interest earning deposits at other financial institutions and overnight federal funds sold which are generally sold for one to three-day periods. Investment Securities All investment securities are classified as available for sale and are carried at fair value with unrealized gains and losses, net of the related deferred income tax effect, excluded from earnings and reported as a separate component of accumulated other comprehensive income until realized. Realized gains and losses are determined using the specific identification method. Declines in the fair value of available for sale securities are evaluated for other-than-temporary impairment (“OTTI”) on a quarterly basis. Impairment is assessed at the individual security level. This assessment considers factors such as the severity, length of time and anticipated recovery period of the impairment, recent events specific to the issuer, including investment downgrades by rating agencies and economic conditions of its industry, and the issuer’s financial condition, capital strength, the presence of credit enhancements, if any, and near-term prospects. The Company also considers its intent and ability to retain the security for a period of time sufficient to allow for a recovery in fair value, or until maturity. The assessment of a security’s ability to recover any decline in fair value, the ability of the issuer to meet contractual obligations, and the Company’s intent and ability to retain the security require considerable judgment. All securities are reviewed for OTTI under the guidance of the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 320, “ Investments - Debt and Equity Securities ” (“ASC 320”). When impairment of a debt security is considered other-than-temporary, the amount of OTTI recorded as a loss within non-interest income and thereby recognized in earnings depends on whether the Company intends to sell the security or whether it is more likely than not that the Company will be required to sell the security before recovery of its amortized cost basis. If the Company intends to (has decided to) sell the debt security or more likely than not will be required to sell the security before recovery of its amortized cost basis, OTTI is recognized in earnings equal to the entire difference between the investment’s amortized cost basis and its fair value. If the Company does not intend to sell the debt security and it is not more likely than not the Company will be required to sell the security before recovery of its amortized cost basis, OTTI is separated into the amount representing credit loss and the amount related to all other market factors. The amount related to credit loss is recognized against earnings. The amount related to other market factors is recognized in other comprehensive income, net of applicable taxes. For equity securities, the entire amount of OTTI is recognized in earnings. Federal Home Loan Bank Stock Federal law requires a member institution of the Federal Home Loan Bank (“FHLB”) system to hold restricted stock of its district Federal Home Loan Bank according to a predetermined formula. This stock is restricted in that it can only be sold to the FHLB or to another member institution and all sales of FHLB stock must be at par. As a result of these restrictions, FHLB stock is carried at cost. Loans Receivable Loans receivable that management has the intent and ability to hold until maturity or payoff are stated at their outstanding unpaid principal balances, net of allowance for loan losses and any deferred fees and costs. Interest income is accrued on the unpaid principal balance. Loan origination fees and costs are deferred and recognized as an adjustment of the yield (interest income) of the related loans. The Company is generally amortizing these amounts over the contractual life of the loan. Management considers a loan to be in delinquency status when the contractual payment of principal or interest has become greater than 30 days past due. The accrual of interest is generally discontinued when the contractual payment of principal or interest has become 90 days past due or management has serious doubts about further collectability of principal or interest, even though the loan is currently performing. A loan may remain on accrual status if it is in the process of collection and is either guaranteed or well secured. When a loan is placed on non-accrual status, unpaid interest credited to income is reversed in the current year. Interest received on non-accrual loans generally is either applied against principal or reported as interest income, according to management’s judgment as to the collectability of principal. Generally, loans are restored to accrual status when the obligation is brought current, has performed in accordance with the contractual terms for a reasonable period of time, and the ultimate collectability of the total contractual principal and interest is no longer in doubt. Allowance for Loan Losses The allowance for loan losses is established through provisions for loan losses charged against income. Loans deemed to be uncollectible are charged against the allowance for loan losses, and subsequent recoveries, if any, are credited to the allowance. Management estimates the allowance for loan losses pursuant to FASB ASC Topic 450, “Contingencies” (“ASC 450”), and FASB ASC Topic 310, “Receivables” (“ASC 310”). Commercial and commercial real estate loans that are considered impaired as defined in ASC 310 are reviewed individually to assess the likelihood and severity of loss exposure. A loan is considered impaired when, based on current information and events, it is probable that the Company will be unable to collect the scheduled payments of principal and interest when due according to the contractual terms of the loan agreement. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis. Factors considered by management in determining impairment include payment status, collateral value, cash flow and the probability of collecting scheduled principal and interest payments when due. Loans subject to individual review are, where appropriate, reserved for according to the present value of expected future cash flows available to repay the loan or the estimated fair value less estimated selling costs of the collateral, if the loan is collateral dependent. Commercial loans excluded from individual assessment, as well as smaller balance homogeneous loans, such as consumer, residential real estate and home equity loans, are evaluated for loss exposure under ASC 450 based upon historical loss rates for each of these categories of loans, adjusted for qualitative factors. The Company does not separately identify individual consumer, home equity, or residential real estate loans for impairment disclosure, unless the loan has been modified as a troubled debt restructuring. The Company records cash receipts on impaired loans that are non-performing as a reduction to principal before applying amounts to interest or late charges unless specifically directed otherwise by the Bankruptcy Court. The Company may continue to recognize interest income on impaired loans where there is no confirmed loss. Loans may be periodically modified in a troubled debt restructuring (“TDR”) to make concessions to help a borrower remain current on the loan and/or to avoid foreclosure, in accordance with FASB Accounting Standard Update (“ASU”) 2012-02, “Receivables (“Subtopic 310”): A Creditor’s Determination of Whether a Restructuring is a Troubled Debt Restructuring” (“ASU 2012-02”). Generally, we do not forgive principal or interest on a loan or modify the interest rate on loans that are below market rates. When we modify loans in a TDR, we evaluate any possible impairment similar to other impaired loans. If we determine that the value of a modified loan is less than the recorded investment in the loan, impairment is recognized through a specific allowance estimate or charge-off to the allowance. The allowance for loan losses is maintained at a level to provide for losses that are inherent within the loan portfolio. This evaluation is inherently subjective as it requires material estimates that may be susceptible to significant change, including the amounts and timing of future cash flows expected to be received on impaired loans. The allowance consists of specific, general and unallocated components. The specific component relates to loans that are classified as either special mention, doubtful, substandard or loss. For such loans that are also classified as impaired, an allowance is established when the discounted cash flows (or collateral value or observable market price) of the impaired loan is lower than the carrying value for that loan. The general component covers non-classified loans and is based on historical loss experience adjusted for qualitative factors. An unallocated component is maintained to cover uncertainties that could affect management’s estimate of probable losses. The unallocated component of the allowance reflects the margin of imprecision inherent in the underlying assumptions used in the methodologies for estimating specific and general losses in the portfolio. Premises and Equipment Land is carried at cost. Buildings, improvements, furniture and equipment are carried at cost, net of accumulated depreciation. Depreciation is computed on the straight-line basis over the estimated useful lives of assets (generally thirty-nine years for buildings and three to fifteen years for furniture and equipment). Leasehold improvements are amortized on the straight-line method over the lesser of the life of the improvements or the lease term. Maintenance and repairs are charged to expense as incurred, while major improvements are capitalized and amortized to operating expense over the identified useful life. Transfers of Financial Assets Transfers of financial assets are accounted for as sales, when control over the assets has been surrendered. Control over transferred assets is deemed to be surrendered when (1) the assets have been isolated from the Company, (2) the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and (3) the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity. Foreclosed Real Estate Foreclosed real estate consists of property acquired in settlement of loans which is carried at its fair value less estimated selling costs. Write-downs from cost to fair value less estimated selling costs are recorded at the date of acquisition or repossession and are charged to the allowance for loan losses. Subsequent write-downs to fair value, net of estimated selling costs, are recorded in non-interest expense along with direct operating expenses. Gains or losses not previously recognized, resulting from the sale of foreclosed assets are recognized in non-interest expense on the date of sale. Foreclosed real estate was $678,000 and $435,000 at December 31, 2018 and 2017, respectively, and was included as a component of other assets in the consolidated statement of financial condition. Proceeds from the sale of foreclosed real estate for the years ended December 31, 2018, 2017 and 2016 were $1.5 million , $331,000 , and $619,000 , respectively. This resulted in a net gain on sale of $44,000 , $8,000 and $9,000 for the years ended December 31, 2018, 2017 and 2016, respectively, and was included as a component of other non-interest expenses in the consolidated statement of income. Bank Owned Life Insurance The Company invests in bank owned life insurance (“BOLI”) as a source of funding for employee benefit obligations. BOLI involves the purchase of life insurance by the Company on a chosen group of employees. The Company is the owner and beneficiary of the policies. This life insurance investment is carried at the cash surrender value of the underlying policies. Income from the increase in the cash surrender value of the underlying policies is included in non-interest income in the consolidated statements of income . Advertising Costs The Company follows the policy of charging the costs of advertising to expense as incurred. Total advertising expense for the years ended December 31, 2018, 2017 and 2016 was $606,000 , $596,000 , and $536,000 , respectively. Income Taxes The Company files a consolidated federal income tax return. The provision for federal and state income taxes is based on income reported on the consolidated financial statements, rather than the amounts reported on the respective income tax returns. Deferred taxes are recorded using the liability method whereby deferred tax assets are recognized for deductible temporary differences and deferred tax liabilities are recognized for taxable temporary differences. Temporary differences are the differences between the reported amounts of assets and liabilities and their tax basis. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion of the deferred tax assets will not be realized. Deferred tax assets and liabilities are adjusted for the effects of changes in tax laws and rates on the date of enactment and the effect of a change in tax rates is recognized in income at that time. In the fourth quarter of 2017, the Tax Cuts and Jobs Act (the “Tax Act”) was signed into law which required the deferred tax assets and liabilities to be revalued using the 21% federal tax rate enacted for tax years beginning after December 31, 2017 from the previous valuation under the prior federal tax rate of 34% . The effect of the revaluation was $262,000 and was recorded in the fourth quarter 2017 tax provision. Refer to Note 10 for more information on the impact of the Tax Act. The Company makes certain estimates and judgments in determining income tax expense for financial statement purposes. These estimates and judgments are applied in the calculation of certain tax credits and in the calculation of deferred income tax expense or benefit associated with certain deferred tax assets and liabilities. Significant changes to these estimates may result in an increase or decrease to the Company’s tax provision in a subsequent period. The Company recognizes interest and/or penalties related to income tax matters in income tax expense. The Company periodically reviews its tax positions and applies a “more likely than not” recognition threshold for all tax uncertainties. The amount recognized is the largest amount of tax benefit that is greater than 50% likely of being realized on examination. For tax positions not meeting the “more likely than not” test, no tax benefit is recorded. Employee Stock Ownership Plan (“ESOP”) Compensation expense is recognized based on the current market price of shares committed to be released to employees. All shares released and committed to be released are deemed outstanding for purposes of earnings per share calculations. Dividends declared and paid on allocated shares held by the ESOP are charged to retained earnings. The value of unearned shares to be allocated to ESOP participants for future services not yet performed is reflected as a reduction of stockholders’ equity. Dividends declared on unallocated shares held by the ESOP are recorded as a reduction of the ESOP’s loan payment to the Company. Stock Compensation Plans At December 31, 2018, the Company had stock-based employee and non-employee compensation plans, which are described more fully in Note 12. The Company accounts for these plans under FASB ASC Topic 718 “ Compensation – Stock Compensation ” (“ASC Topic 718”). The Company accounts for the plans using a fair value-based method, which measures compensation cost at the grant date based on the fair value of the award. Compensation is then recognized over the service period, which is usually the vesting period. The fair value of stock option grants are estimated on the date of grant using the Black-Scholes options-pricing model. Common shares are issued from the Company’s authorized common shares when a share option is exercised. Common shares awarded as restricted stock are expensed based on the fair market value at the grant date. The stock option plan, restricted stock plan and equity incentive plan expenses are recognized in salaries and employee benefits expense on the consolidated statement of income. Earnings per Common Share Basic earnings per share is computed by dividing net income by the weighted average number of common shares outstanding, less unallocated shares held by the Company’s ESOP, 2006 Recognition and Retention Plan (“RRP”) and 2012 Equity Incentive Plan (“EIP”), during the period. Diluted earnings per share reflects additional common shares that would have been outstanding if dilutive potential common shares had been issued, as well as any adjustment to income that would result from the assumed conversion. Potential common shares that may be issued by the Company relate solely to outstanding stock options and restricted stock awards, and are determined using the treasury stock method. Off-Balance Sheet Credit Related Financial Instruments In the ordinary course of business, the Company has entered into commitments to extend credit. Such commitments are recorded in the consolidated statement of financial condition when they are funded. Comprehensive Income Accounting principles generally require that recognized revenue, expenses, gains, and losses be included in net income. Although certain changes in assets and liabilities, such as unrealized gains and losses on available for sale securities and OTTI related to non-credit factors, are reported as a separate component of the stockholders’ equity section of the consolidated statement of financial condition, such items, along with net income, are components of comprehensive income. Restrictions on Cash and Due from Banks The Company is required to maintain reserve funds in cash or on deposit with the Federal Reserve Bank. The required reserve at December 31, 2018 and 2017 was $2,790,000 and $2,738,000 , respectively. Subsequent Events The Company evaluated events occurring subsequent to December 31, 2018 through the date the consolidated financial statements are being issued, and other than as set forth in Note 22, did not identify any subsequent events requiring disclosure pursuant to the provisions of FASB ASC Topic 855. Impact of Adoption of Recent Accounting Standards The Company adopted FASB ASU 2014-09 “Revenue from Contracts with Customers (Topic 606)” (“ASU 2014-09”) on January 1, 2018. The objective of ASU 2014-09 is to align the recognition of revenue with the transfer of promised goods or services provided to customers in an amount that reflects consideration which the entity expects to be entitled in exchange for those goods or services. The guidance in this update supersedes the revenue recognition requirements in ASC Topic 605 “Revenue Recognition” , and most industry-specific guidance throughout the industry topics of Codification. Based on management’s evaluation of ASU 2014-09, substantially all of the Company’s interest income and non-interest income were not impacted by the adoption of ASU 2014-09 because the revenue from those contracts with customers is covered by other guidance in U.S. GAAP or the revenue recognition outcomes are similar to the Company’s current revenue recognition practices. The Company evaluated certain noninterest revenue streams, including, deposit related fees, service and interchange fees, merchant income and gains (losses) on the sale of owned real estate (“OREO”) to determine the potential impact of the guidance on the Company’s consolidated financial statements. The Company concluded that a prior period adjustment was not needed upon adoption of ASU 2014-09 using the modified retrospective method. Since the guidance does not apply to revenue associated with financial instruments, the adoption of ASU 2014-09 did not have a material effect on the Company’s consolidated financial statements. The additional disclosures required by ASU 2014-09 have been included in Note 21. The Company adopted FASB ASU 2016-01 “Financial Instruments – Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities” (“ASU 2016-01”) on January 1, 2018. The update enhances the reporting model for financial instruments to provide users of financial statements with more decision-useful information by updating certain aspects of recognition, measurement, presentation and disclosure of financial instruments. Among other changes, the update requires public business entities to: a) use the exit price notion when measuring the fair value of financial instruments for disclosure purposes; b) requires equity investments (except those accounted for under the equity method of accounting or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income; and c) clarifies that entities should evaluate the need for a valuation allowance on a deferred tax asset related to available for sale securities in combination with the entities’ other deferred tax assets. The requirement to use the exit price method for the fair value measurement of financial instruments did not have an impact on the Company’s consolidated financial statements upon adoption of ASU 2016-01, as the Company had elected to use this method in prior reporting periods. The requirement to record changes in the fair value of equity securities in net income did not have a material impact on the Company’s consolidated financial statements upon adoption of ASU 2016-01. The adoption of ASU 2016-01 did not have any impact on the valuation allowance of deferred tax assets related to available for sale securities. The Company adopted FASB ASU 2018-02, “Income Statement – Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income” (ASU 2018-02) on January 1, 2018. ASU 2018-02 was issued to address the income tax accounting treatment of the stranded tax effects within other comprehensive income. This issue came about from the enactment of the Tax Act on December 22, 2017 that changed the Company’s tax rate from 34% to 21%. ASU 2018-02 allowed an entity to elect a reclassification from accumulated other comprehensive income (“AOCI”) to retained earnings for stranded tax effects resulting from the Tax Act. The amount of that reclassification includes the effect of tax rate changes on the deferred tax amount, any related valuation allowance and other income tax effects on the items in AOCI. Upon adoption of ASU 2018-02, the Company reclassified the income tax effect of the Tax Act from AOCI to retained earnings. The reclassification increased AOCI and decreased retained earnings by $156,000 , with zero net effect on total stockholders’ equity. The Company uses the individual security approach for all available for sale securities when releasing income tax effects remaining in AOCI. New Accounting Standards The following are new accounting standards that have been previously disclosed but not yet adopted and includes additional information on the impact the adoption of the standard will have on the Company’s consolidated financial statements: In February 2016, the FASB issued ASU 2016-02 “Leases (Topic 842)” (“ASU 2016-02”). The guidance in the update supersedes the requirements in ASC Topic 840, Leases. The guidance is intended to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet for leases with lease terms of more than 12 months. For public companies, this update will be effective for interim and annual periods beginning after December 15, 2018, and can be applied on a modified retrospective or a transition approach basis. The Company expects to use the transition approach basis, which will allow us to apply ASU 2016-02 at the adoption date, as opposed to applying ASU 2016-02 at the beginning of the earliest period presented. The Company currently has two operating leases that will result in recognition of lease assets and lease liabilities on the consolidated statements of financial condition. The amount of assets and liabilities added to the consolidated statements of financial condition are not expected to have a material impact on the Company’s consolidated financial statements per preliminary estimates. In June 2016, the FASB issued ASU 2016-13, “Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments” (ASU 2016-13). ASU 2016-13 requires credit losses on most financial assets measured at amortized cost and certain other instruments to be measured using an expected credit loss model (referred to as the current expected credit loss (“CECL”) model). Under the CECL model entities will estimate credit losses over the entire contractual term of the instrument (considering estimated prepayments, but not expected extensions or modifications unless reasonable expectation of a troubled debt restructuring exists) from the date of initial recognition of that instrument. Further, ASU 2016-13 made certain targeted amendments to the existing impairment standards for available for sale (“AFS”) debt securities. For an AFS debt security for which there is neither the intent nor a more-likely-than-not requirement to sell, an entity will record credit losses as an allowance rather than a write-down of the amortized cost basis. ASU 2016-13 is effective for public companies that are U.S. Securities and Exchange Commission (“SEC”) filers for fiscal periods beginning after December 15, 2019, including interim reporting periods within those periods. An entity will apply the amendments in ASU 2016-13 through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective. The Company is developing its approach for determining the expected credit losses under the new guidance. Alternative methodologies are being considered, data requirements and integrity are being reviewed and enhancements to the current process are being considered. We expect that the new guidance will result in an increase to the allowance for loan losses given that the allowance will be required to cover the full remaining expected life of the portfolio, rather than the incurred loss under the current accounting standard. The extent of this increase is still being evaluated. We are also reviewing the impact of additional disclosures required under ASU 2016-13 on our ongoing financial reporting procedures . Reclassifications Certain amounts in the 2017 and 2016 consolidated financial statements have been reclassified to conform with the 2018 presentation format. These reclassifications had no effect on net income.

At December 31, 2018, thirty-two municipal bonds with a cost of $ 11.0 million and fair value of $ 11.2 million were pledged under a collateral agreement with the Federal Reserve Bank (“FRB”) of New York for liquidity borrowing. At December 31, 2017, thirty-three municipal bonds with a cost of $11.3 million and fair value of $11.7 million were pledged with the FRB. In addition, at December 31, 2018, twenty-two municipal bonds with a cost and fair value of $ 5.6 million were pledged as collateral for customer deposits in excess of Federal Deposit Insurance Corporation (“FDIC”) insurance limits. At December 31, 2017, twenty municipal bonds with a cost of $5.1 million and fair value of $5.3 million were pledged as collateral for customer deposits in excess of FDIC insurance limits.

At December 31, 2018, the Company’s investment portfolio included several debt securities in the “unrealized losses less than twelve months” category. The debt securities were not evaluated further for OTTI as the unrealized losses on the individual securities were less than 20% of book value, which management deemed to be immaterial, the securities were issued by government sponsored enterprises and management has the intent and ability to hold these securities.  At December 31, 2018, the Company had several securities in the “unrealized losses twelve months or more” category. These securities were not evaluated further for OTTI, as the unrealized losses were less than 20% of book value and management has the intent and ability to hold these securities. Management believes the temporary impairments were due to declines in fair value resulting from changes in interest rates and/or increased credit liquidity spreads since the securities were purchased. Management completed an OTTI analysis for two private label asset-backed securities, which did not have unrealized losses as of December 31, 2018. Management concluded that there was a limited risk of principal losses for these securities and that additional OTTI charges were not required as of December 31, 2018 on these securities. The unrealized losses on debt securities shown in the previous tables were recorded as a component of other comprehensive loss, net of tax benefit on the Company’s consolidated statements of stockholders’ equity. The following table presents a summary of the credit-related OTTI charges recognized as components of income:   For The Years Ended December 31,  2018 2017  (Dollars in thousands)  Beginning balance $ 435 $ 554  Additions:  Credit loss not previously recognized - -  Reductions:  Losses realized during the period on OTTI previously recognized - -  Receipt of cash flows on previously recorded OTTI (88) (119)  Ending balance $ 347 $ 435  A deterioration in credit quality and/or other factors that may limit the liquidity of a security in our portfolio might adversely affect the fair values of the Company’s investment portfolio and may increase the potential that certain unrealized losses will be designated as “other-than-temporary” and that the Company may incur additional write-downs in future periods.  During the year ended December 31, 2018, the Company did no t sell any available for sale debt securities. During the year ended December 31, 2017, the Company sold eighteen municipal bonds for total proceeds of $6.5 million resulting in realized gains of $244,000 . During the year ended December 31, 2016, the Company sold nine U.S. Treasury Bonds for total proceeds of $14.4 million resulting in realized gains of $1.6 million.  Equity Securities  At December 31, 2018 and 2017, available for sale equity securities consisted of 22,368 shares of Federal Home Loan Mortgage Corporation (“FHLMC”) common stock. During the year ended December 31, 2018, the Company recognized an unrealized gain of $2,000 on the equity securities, which was recorded in non-interest income in the consolidated statements of income. There were no sales of equity securities during the years ended December 31, 2018, 2017 or 2016.

Residential real estate loans serviced for others by the Company totaled $20.1 million and $21.8 million at December 31, 2018 and 2017, respectively.  At December 31, 2018, $107.8 million of one- to four-family residential real estate loans were pledged as collateral for advances from the FHLB.  Most loans made by the Company are secured by borrowers’ personal or business assets. The Company considers a concentration of credit to a particular industry to exist when the aggregate credit exposure to a borrower or group of borrowers in that industry exceeds 25% of the Bank’s capital plus reserves or 10% of total loans. At December 31, 2018, the Company held concentrations of credit in the particular industries noted below:  • $73.7 million in investor owned multifamily real estate loans, which equated to 92.4% of the Bank’s capital reserves; and • $32.4 million in real estate loans on office properties, which equated to 40.6% of the Bank’s capital reserves.  Although these loan categories exceeded the concentration parameter, borrowers within these loan types are diversified and the properties are located in various locations throughout western New York.  The ability of the Company’s residential and consumer borrowers to honor their repayment commitments is generally dependent on the level of overall economic activity within the geographical area they reside. Commercial borrowers’ ability to repay is generally dependent upon the general health of the economy. Substantially all of the Company’s loans are in western New York State and, accordingly, the ultimate collectability of a substantial portion of the loans is susceptible to changes in market conditions in this primary market area.

Allowance for Loan Losses

Allowance for Loan Losses [Abstract]
Allowance for Loan Losses	Note 5 - Allowance for Loan Losses  Management segregates the loan portfolio into loan types and analyzes the risk level for each loan type when determining its allowance for loan losses. The loan types are as follows:  Real Estate Loans: · One- to Four-Family – are loans secured by first lien collateral on residential real estate primarily held in the Western New York region. These loans can be affected by economic conditions and the value of underlying properties. Western New York’s housing market has consistently demonstrated stability in home prices despite economic conditions. Furthermore, the Company has conservative underwriting standards and its residential lending policies and procedures ensure that its one- to four-family residential mortgage loans generally conform to secondary market guidelines. · Home Equity - are loans or lines of credit secured by first or second liens on owner-occupied residential real estate primarily held in the Western New York region. These loans can also be affected by economic conditions and the values of underlying properties. Home equity loans may have increased risk of loss if the Company does not hold the first mortgage resulting in the Company being in a secondary position in the event of collateral liquidation. The Company does not originate interest only home equity loans. · Commercial Real Estate – are loans used to finance the purchase of real property, which generally consists of developed real estate that is held as first lien collateral for the loan. These loans are secured by real estate properties that are primarily held in the Western New York region. Commercial real estate lending involves additional risks compared with one- to four-family residential lending, because payments on loans secured by commercial real estate properties are often dependent on the successful operation or management of the properties, and/or the collateral value of the commercial real estate securing the loan, and repayment of such loans may be subject to adverse conditions in the real estate market or economic conditions to a greater extent than one- to four-family residential mortgage loans. Also, commercial real estate loans typically involve relatively large loan balances concentrated with single borrowers or groups of related borrowers. · Construction – are loans to finance the construction of either one- to four-family owner occupied homes or commercial real estate. At the end of the construction period, the loan automatically converts to either a one- to four-family or commercial mortgage, as applicable. Risk of loss on a construction loan depends largely upon the accuracy of the initial estimate of the value of the property at completion compared to the actual cost of construction. The Company limits its risk during construction as disbursements are not made until the required work for each advance has been completed and an updated lien search is performed. The completion of the construction progress is verified by a Company loan officer or inspections performed by an independent appraisal firm. Construction loans also expose us to the risk of construction delays which may impair the borrower’s ability to repay the loan.  Other Loans: · Commercial – includes business installment loans, lines of credit, and other commercial loans. Most of our commercial loans have fixed interest rates, and are for terms generally not in excess of 5 years. Whenever possible, we collateralize these loans with a lien on business assets and equipment and require the personal guarantees from principals of the borrower. Commercial loans generally involve a higher degree of credit risk . As commercial loans can involve relatively large loan balances to a single borrower or groups of related borrowers, with the repayment of such loans typically dependent on the successful operation of the commercial business and the income stream of the borrower. Such risks can be significantly affected by economic conditions. Although commercial loans may be collateralized by equipment or other business assets, the liquidation of collateral in the event of a borrower default may be an insufficient source of repayment because the equipment or other business assets may be obsolete or of limited use, among other things. Accordingly, the repayment of a commercial loan depends primarily on the credit worthiness of the borrowers (and any guarantors), while liquidation of collateral is a secondary and often insufficient source of repayment. · Consumer – consist of loans secured by collateral such as an automobile or a deposit account, unsecured loans and lines of credit. Consumer loans tend to have a higher credit risk due to the loans being either unsecured or secured by rapidly depreciable assets. Furthermore, consumer loan payments are dependent on the borrower’s continuing financial stability, and therefore are more likely to be adversely affected by job loss, divorce, illness or personal bankruptcy.  The allowance for loan losses is a valuation account that reflects the Company’s evaluation of the losses inherent in its loan portfolio. In order to determine the adequacy of the allowance for loan losses, the Company estimates losses by loan type using historical loss factors, as well as other environmental factors, such as trends in loan volume and loan type, loan concentrations, changes in the experience, ability and depth of the Company’s lending management, and national and local economic conditions. The Company's determination as to the classification of loans and the amount of loss allowances are subject to review by bank regulators, which can require the establishment of additional loss allowances.  The Company also reviews all loans on which the collectability of principal may not be reasonably assured, by reviewing payment status, financial conditions and estimated value of loan collateral. These loans are assigned an internal loan grade, and the Company assigns an amount of loss allowances to these classified loans based on loan grade.  Although the allocations noted below are by loan type, the allowance for loan losses is general in nature and is available to offset losses from any loan in the Company’s portfolio. The unallocated component of the allowance for loan losses reflects the margin of imprecision inherent in the underlying assumptions used in the methodologies for existing specific and general losses in the portfolio.  The fol lowing tables summarize the activity in the allowance for loan losses for the years ended December 31, 2018, 2017 and 2016 and the distribution of the allowance for loan losses and loan receivable by loan portfolio class and impairment method as of December 31, 2018 and December 31, 2017:    Real Estate Loans Other Loans  One- to Four-Family (2) Home Equity Commercial Construction - Commercial Commercial Consumer Unallocated Total  (Dollars in thousands)  December 31, 2018  Allowance for Loan Losses:  Balance – January 1, 2018 $ 511 $ 122 $ 1,663 $ 347 $ 544 $ 35 $ 61 $ 3,283  Charge-offs (23) - (181) - - (51) - (255)  Recoveries 19 2 1 - 1 7 - 30  Provision (Credit) (36) (33) 537 (97) (38) 34 23 390  Balance – December 31, 2018 $ 471 $ 91 $ 2,020 $ 250 $ 507 $ 25 $ 84 $ 3,448  Ending balance: individually evaluated for impairment $ - $ - $ 30 $ - $ - $ - $ - $ 30  Ending balance: collectively evaluated for impairment $ 471 $ 91 $ 1,990 $ 250 $ 507 $ 25 $ 84 $ 3,418   Gross Loans Receivable (1) :  Ending balance $ 155,024 $ 41,830 $ 150,475 $ 22,252 $ 21,825 $ 1,156 $ - $ 392,562  Ending balance: individually evaluated for impairment $ 178 $ - $ 382 $ - $ - $ - $ - $ 560  Ending balance: collectively evaluated for impairment $ 154,846 $ 41,830 $ 150,093 $ 22,252 $ 21,825 $ 1,156 $ - $ 392,002  (1) Gross Loans Receivable does not include allowance for loan losses of $ (3,448) or deferred loan costs of $ 3,357 .

A loan is considered impaired when, based on current information and events, it is probable that the Company will not be able to collect the scheduled payments of principal and interest when due according to the contractual terms of the loan agreement. Factors considered in determining impairment include payment status, collateral value and the probability of collecting scheduled payments when due. Impairment is measured on a loan-by-loan basis for commercial real estate loans and commercial loans. Larger groups of smaller balance homogeneous loans are collectively evaluated for impairment. Accordingly, the Company does not separately identify individual consumer, home equity, or one- to four-family loans for impairment disclosure, unless they are subject to a troubled debt restructuring.  The following is a summary of information pertaining to impaired loans at or for the periods indicated:   Unpaid Average Interest  Recorded Principal Related Recorded Income  Investment Balance Allowance Investment Recognized  For the Year Ended  At December 31, 2018 December 31, 2018  (Dollars in thousands)  With no related allowance recorded:  Residential, one- to four-family $ 178 $ 178 $ - $ 180 $ 12  Home equity (1) - - - 17 -  Commercial real estate 134 134 - 356 -  Commercial loan (1) - - - 59 1  Total impaired loans with no related allowance 312 312 - 612 13   With an allowance recorded:  Commercial real estate ( 2 ) 248 248 30 1,249 4  Total impaired loans with an allowance 248 248 30 1,249 4   Total of impaired loans:  Residential, one- to four-family 178 178 - 180 12  Home equity - - - 17 -  Commercial real estate 382 382 30 1,605 4  Commercial loans - - - 59 1  Total impaired loans $ 560 $ 560 $ 30 $ 1,861 $ 17  (1) These loans were either paid off or foreclosed upon during the year ended December 31, 2018.

The accrual of interest on loans is discontinued when, in management’s opinion, the borrower may be unable to meet payments as they become due. A loan does not have to be 90 days delinquent in order to be classified as non-accrual. When interest accrual is discontinued, all unpaid accrued interest is reversed. If ultimate collection of principal is in doubt, all cash receipts on impaired loans are applied to reduce the principal balance. Interest income not recognized on non-accrual loans during the years ended December 31, 2018, 2017 and 2016 was $ 237,000 , $ 265,000 , and $ 366,000 , respectively.  The Company’s policies provide for the classification of loans as follows: · Pass/Performing; · Special Mention – does not currently expose the Company to a sufficient degree of risk but does possess credit deficiencies or potential weaknesses deserving the Company’s close attention; · Substandard – has one or more well-defined weaknesses and are characterized by the distinct possibility that the Company will sustain some loss if the deficiencies are not corrected. A substandard asset would be one inadequately protected by the current net worth and paying capacity of the obligor or pledged collateral, if applicable; · Doubtful – has all the weaknesses inherent in substandard loans with the additional characteristic that the weaknesses present make collection or liquidation in full on the basis of currently existing facts, conditions and values questionable, and there is a high possibility of loss; and · Loss – loan is considered uncollectible and continuance without the establishment of a specific valuation reserve is not warranted.  The Company’s Asset Classification Committee is responsible for monitoring risk ratings and making changes as deemed appropriate. Each commercial loan is individually assigned a loan classification. The Company’s consumer loans, including residential one- to four-family loans and home equity loans, are not classified as described above. Instead, the Company uses the delinquency status as the basis for classifying these loans. Generally, all consumer loans more than 90 days past due are classified and placed in non-accrual. Such loans that are well-secured and in the process of collection will remain in accrual status.  The following tables summarize the internal loan grades applied to the Company’s loan portfolio as of December 31, 2018 and December 31, 2017:    Pass/Performing Special Mention Substandard Doubtful Loss Total  (Dollars in thousands)  December 31, 2018  Real Estate Loans:  Residential, one- to four-family (1) $ 152,039 $ - $ 2,985 $ - $ - $ 155,024  Home equity 41,346 - 484 - - 41,830  Commercial 148,149 376 1,950 - - 150,475  Construction - Commercial 22,252 - - - - 22,252  Other Loans:  Commercial 20,722 61 1,042 - - 21,825  Consumer 1,153 - 3 - - 1,156  Total $ 385,661 $ 437 $ 6,464 $ - $ - $ 392,562  (1) Includes one- to four-family construction loans.

Troubled debt restructurings (“TDRs”) occur when we grant borrowers concessions that we would not otherwise grant but for economic or legal reasons pertaining to the borrower’s financial difficulties. A concession is made when the terms of the loan modification are more favorable than the terms the borrower would have received in the current market under similar financial difficulties. These concessions may include, but are not limited to, modifications of the terms of the debt, the transfer of assets or the issuance of an equity interest by the borrower to satisfy all or part of the debt, or the addition of borrower(s). The Company identifies loans for potential TDRs primarily through direct communication with the borrower and evaluation of the borrower’s financial statements, revenue projections, tax returns, and credit reports. Even if the borrower is not presently in default, management will consider the likelihood that cash flow shortages, adverse economic conditions, and negative trends may result in a payment default in the near future. Generally, we will not return a TDR to accrual status until the borrower has demonstrated the ability to make principal and interest payments under the restructured terms for at least six consecutive months. The Company’s TDRs are impaired loans, which may result in specific allocations and subsequent charge-offs if appropriate.  Some loan modifications classified as TDRs may not ultimately result in full collection of principal and interest, as modified, which may result in potential losses. These potential losses have been factored into our overall estimate of the allowance for loan losses. The following table summarizes the loans that were classified as TDRs as of the dates indicated:     Non-Accruing Accruing TDRs That Have Defaulted on Modified Terms Year to Date  Number of Loans Recorded Investment Number of Loans Recorded Investment Number of Loans Recorded Investment Number of Loans Recorded Investment  (Dollars in thousands)  At December 31, 2018  Real Estate Loans:  Residential, one- to four-family 5 $ 178 1 $ 34 4 $ 144 1 $ 34    At December 31, 2017  Real Estate Loans:  Residential, one- to four-family 5 $ 184 - $ - 5 $ 184 - $ -  Home equity 2 21 1 19 1 2 - -  Total 7 $ 205 1 $ 19 6 $ 186 - $ -  No additional loan commitments were outstanding to these borrowers at December 31, 2018 and 2017.  There were no loans restructured and classified as TDRs during the year ended December 31, 2018.  The following table details the activity in loans which were first deemed to be TDRs during the year ended December 31, 2017:     For The Years Ended December 31, 2017  Number of Loans Pre-Modification Outstanding Recorded Investment Post-Modification Outstanding Recorded Investment  (Dollars in thousands)  Real Estate Loans:  Residential, one- to four-family 1 $ 29 $ 29  Foreclosed real estate consists of property acquired in settlement of loans which is carried at its fair value less estimated selling costs. Write-downs from cost to fair value less estimated selling costs are recorded at the date of acquisition or repossession and are charged to the allowance for loan losses. Foreclosed real estate was $ 678,000 and $435,000 at December 31, 2018 and 2017, respectively, and was included as a component of other assets on the consolidated statements of financial condition. The recorded investment of consumer mortgage loans secured by residential real estate properties for which formal foreclosure proceedings are in process according to local requirements of the applicable jurisdiction was $1.1 million and $965,000 at December 31, 2018 and December 31, 2017, respectively.

At December 31, 2018, the Company had written agreements with the FHLBNY which allows it to borrow up to the maximum lending values designated by the type of collateral pledged. As of December 31, 2018 and 2017, our maximum lending value was $ 107.8 million and $ 105.9 million, respectively, and was collateralized by a pledge of certain, fixed-rate residential, one- to four-family loans. At December 31, 2018 and 2017, we had advances outstanding under this agreement of $ 24.7 million and $27.0 million, respectively. All of the advances outstanding at December 31, 2018 and 2017 were term borrowings at fixed rates. We have a written agreement with the Federal Reserve Bank discount window for overnight borrowings which is collateralized by a pledge of our securities, and allows us to borrow up to the value of the securities pledged, which was equal to a book value of $ 11.0 million and $11.3 million at December 31, 2018 and 2017, respectively. Fair value of the pledged securities was equal to $11.2 million and $11.7 million as of December 31, 2018 and 2017, respectively. There were no balances outstanding with the Federal Reserve Bank as of December 31, 2018 and 2017.

Income Taxes [Abstract]
Income Taxes	Note 10- Income Taxes On December 22, 2017, the U.S. government enacted the Tax Act, a comprehensive tax legislation which, among other things, reduced the federal income tax rate for corporations from 34% to 21% effective on January 1, 2018. The Tax Act resulted in broad and complex changes to the Internal Revenue Code which will impact the Company, including updates to business-related tax exclusions, deductions and credits.  The Company’s deferred federal and state income tax and related valuation accounts represent the estimated impact of temporary differences between how we recognize our assets and liabilities under GAAP and how such assets and liabilities are recognized under federal and state tax law. Deferred tax assets and liabilities are determined based on the difference between the financial statement and tax bases of assets and liabilities as measured by the enacted tax rates which will be in effect when these differences reverse. GAAP accounting required that the impact of the Tax Act be accounted for in the period of enactment. As a result of the reduction in the U.S. corporate income tax rate from 34% to 21% under the Tax Act, the Company revalued its ending net deferred tax assets as of December 31, 2017. The Company recognized a $262,000 net tax expense in the Company’s consolidated statements of income for the year ended December 31, 2017 as a result of the enactment of the Tax Act and revaluation of the Company’s net deferred tax assets.  The deferred tax liability related to available for sale (“AFS”) security gains that were revalued as of December 31, 2017 as a result of the Tax Act, created “stranded tax effects” in Accumulated Other Comprehensive Income (“AOCI”). In February 2018, FASB issued ASU 2018-02 “Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income (Topic 220)” (“ASU 2018-02”), which allowed an entity to elect to reclassify from AOCI to retained earnings the stranded tax effects resulting from the Tax Act. The Company elected not to early adopt the provisions of the ASU 2018-02 for the year ended December 31, 2017. The Company retrospectively recorded a one-time reclassification of $156,000 from AOCI to retained earnings in the consolidated statement of equity for stranded tax effects resulting from the newly enacted corporate tax rate for the quarter ended March 31, 2018. The amount of the reclassification represents the difference between the 34 percent historical corporate tax rate and the newly enacted 21 percent corporate tax rate.  The provision for income tax expense consists of the following:   Years Ended December 31,  2018 2017 2016  (Dollars in thousands)   Current:  Federal $ 446 $ 960 $ 989  State 4 6 8  Total Current 450 966 997   Deferred:  Federal  Federal - expected 135 (43) (222)  Federal - Deferred tax asset remeasurement (1) - 262 -  State - - -  Total Deferred 135 219 (222)   Total Income Tax Expense $ 585 $ 1,185 $ 775  (1) Represents a charge to write-down deferred tax assets due to the enactment of the Tax Act.  A reconciliation of the statutory federal income tax at a rate of 21% for the year ended December 31, 2018 and 34% for the years ended December 31, 2017 and 2016 to the income tax expense included in the statements of income is as follows:   Years Ended December 31,  2018 2017 2016   Federal income tax at statutory rate 21.0 % 34.0 % 34.0 %  State benefit, net of federal expense (2.9) (2.2) (0.8)  Tax-exempt interest income (7.3) (12.3) (14.7)  Deferred tax valuation allowance 3.0 2.3 1.0  Deferred tax remeasurement due to Tax Act - 5.8 -  Life insurance income (1.8) (2.7) (2.2)  Other 0.8 1.1 0.8  Total Income Tax Expense 12.8 % 26.0 % 18.1 %  The tax effects of temporary differences that give rise to significant portions of deferred tax assets and liabilities are as follows:    December 31,  2018 2017  (Dollars in thousands)  Deferred tax assets:  Deferred compensation $ 1,091 $ 1,062  Allowance for loan losses 879 838  Net Operating Loss ("NOL") 347 223  Impairment of equity investments 127 128  Accrued expenses 111 103  Stock options granted 9 5  Alternative Minimum Tax ("AMT") credit - 180  Other 50 5  Total Deferred Tax Assets 2,614 2,544   Deferred tax liabilities:  Deferred loan origination costs (856) (801)  Depreciation (322) (296)  Prepaid expenses (79) (92)  Unrealized gains on securities available for sale (34) (251)  Total Deferred Tax Liabilities (1,291) (1,440)   Deferred tax valuation allowance (638) (502)   Net Deferred Tax Asset $ 685 $ 602  The net deferred tax asset was recorded in other assets on the consolidated statements of financial condition at December 31, 2018 and 2017. 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 carry-backs, 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 carry-backs, 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, 2018, except for the following:  · Valuation allowance of $ 127,000 on the deferred tax asset for the 2011 other than temporary impairment charge; and · Valuation allowance of $ 511,000 on state deferred tax assets.  Management believes that the Company will not generate sufficient income of the appropriate character (i.e. capital gains) to utilize any of the deferred tax asset created by the 2011 other than temporary impairment charge. Management believes that it is more likely than not that the Company will not realize its state deferred tax assets because of reform in New York State corporate tax law. Beginning in 2015, the most significant change in the tax law allows the Company to deduct up to 50 % of its net interest income received from qualifying loans. This change effectively eliminates the Company’s New York State tax on income resulting in the Company being taxed on its apportioned capital. Because of this tax reform, the Company will not generate sufficient taxable income within New York State to realize its existing state deferred tax assets and therefore, a deferred tax valuation allowance of $137,000 and $ 167,000 was recorded during 2018 and 2017, respectively.  The accounting for the effects of the tax rate change resulting from the Tax Act on deferred tax balances is complete and no provisional amounts were recorded for this item.  Under prior federal law, tax bad debt reserves created prior to January 1, 1998 were subject to recapture into taxable income should the Company fail to meet certain qualifying asset and definition tests. The 1996 federal legislation eliminated these thrift related recapture rules. However, under current law, pre-1988 reserves remain subject to recapture should the Company make certain non-dividend distributions or cease to maintain a thrift or bank charter. Management has no intention of taking any such actions. At December 31, 2018 and 2017, the Company’s total pre-1988 tax bad debt reserve was $ 2.2 million. This reserve reflects the cumulative effect of federal tax deductions by the Company for which no federal income tax provision has been made.  ASC 740 “Income Taxes” prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return, and also provides guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure and transition. The Company recognized no adjustment for unrecognized income tax benefits for the years ended December 31, 2018 and 2017. As of December 31, 2018, there has been no material change in any uncertain tax position. The Company’s policy is to recognize interest and penalties on unrecognized tax benefits in income tax expense in the Consolidated Statements of Income.  The Company’s Federal and New York State tax returns, constituting the returns of the major taxing jurisdictions, are subject to examination by the taxing authorities for all open years as prescribed by applicable statute. No waivers have been executed that would extend the period subject to examination beyond the period prescribed by statute. The federal tax returns for the years ended December 31, 2015 , 2016 and 2017 remain subject to examination by the IRS. The tax returns for the years ended December 31, 2015 , 2016 and 2017 for New York State also remain subject to examination.

Employee and Director Benefit Plans [Abstract]
Employee and Director Benefit Plans	Note 11 - Employee and Director Benefit Plans  401K Plan  The Company maintains a 401(k) savings plan covering employees who have completed three months of service and attained age 21. Participants may make contributions to the 401(k) Plan in the form of salary deferrals of up to 75 % of their total compensation subject to certain IRS limitations. The plan consists of three components: 401(k), Profit Sharing and Safe Harbor. For the 401(k) component, the Company makes a matching contribution equal to 40 % of the participant salary deferral, up to 6 % of such employee’s compensation after one year of service. For the profit sharing component, the Company makes a discretionary contribution, up to 5.1 % of an eligible employee’s salary, depending on years of service. Lastly, the Company contributes 3.4 % of an eligible employee’s salary based on years of service, which is a discretionary contribution to the Safe Harbor component of the plan. The Company’s expense for all three components of the 401(k) plan for the years ended December 31, 2018, 2017 and 2016 was $ 485,000 , $ 434,000 , and $ 426,000 , respectively.  1999 Supplemental Benefit Plans  Effective October 1, 1999, the Company initiated a non-qualified Executive Supplemental Benefit Plan and a non-qualified Directors Supplemental Benefit Plan. Both plans are unfunded and provide a predefined annual benefit to be paid to executives and directors for fifteen years upon their retirement. Although the plans are unfunded, the Company has purchased bank owned life insurance for the purpose of funding the liability. The cash surrender value of bank owned life insurance amounted to $ 7.4 million and $ 7.3 million at December 31, 2018 and 2017, respectively. Annual benefits increase at a predetermined amount until the executive or director reaches a predetermined retirement age. Predefined benefits are 100% vested at all times and in the event of death, are guaranteed to continue at the full amount to their designated beneficiaries. The Company had a liability under such plans of $ 1.0 million and $ 1.2 million at December 31, 2018 and 2017, respectively. This liability was recorded in other liabilities on the consolidated statement of financial condition and was calculated using an assumed discount rate of 6.17 % in 2018 and 2017.  The Company’s expense for the 1999 Plans was $ 69,000 for the year ended December 31, 2018 and $75,000 and $96,000 for the years ended December 31, 2017 and 2016, respectively.  2001 and 2012 Supplemental Benefit Plans  Effective October 1, 2001, the Company initiated a non-qualified Executive Supplemental Benefit Plan and a non-qualified Director’s Supplemental Benefit Plan (collectively, the “2001 Plans”). The Company amended and restated the 2001 plans effective November 1, 2015.  Effective January 27, 2016, the Company amended the 2001 Supplemental Benefit Plan for Directors, resulting in a change to the benefit formula from a fixed, pre-determined dollar benefit. The formula provides a benefit equal to a percentage of the director’s average pay. The average pay is multiplied by number of years of service, not to exceed 20 years of service or 40% of average final pay. The benefit is payable over a period of fifteen years beginning the month following age 72, unless termination occurs due to disability, death or a change in control.  Effective May 18, 2016, the Company amended the 2001 Supplemental Benefit Plan for Executives resulting in a change in the benefit formula from a fixed, pre-determined dollar benefit to a formula-based benefit. The formula provides a benefit equal to a percentage of the executive’s average pay. The average pay is multiplied by number of years of service, not to exceed 20 years of service or 40% of average final pay. A reduced benefit is payable if a termination of service occurs prior to age 65. The benefit is payable over a period of fifteen years beginning the month following age 65, unless termination occurs due to disability, death or a change in control.  The 2001 Plans are unfunded. The Company had a liability under these plans of $2.3 million and $2.2 million at December 31, 2018 and 2017, respectively. This liability was recorded in other liabilities on the consolidated statements of financial condition and was calculated using an assumed discount rate of 6.17% in 2018 and 2017.  Effective June 30, 2012, the Company implemented a Supplemental Executive Benefit Plan (the “2012 Plan”) with one executive. The 2012 Plan provides that when the Executive attains age 67 , the Executive will be entitled to a fixed, pre-determined annual benefit under the 2012 Plan, which will be paid in monthly installments for 15 years. The 2012 Plan was amended on May 18, 2016 to update the fixed, pre-determined annual benefit amount. The 2012 Plan provides for a reduced benefit in the event the Executive terminates his employment for a reason other than death, disability, cause or a change in control, before the Executive attains the age 67 , which will be paid in monthly installments for 15 years. In the event of death, the vested benefit is payable to the beneficiary as a lump sum payment. The Company had a liability under this plan of $ 587,000 and $ 450,000 as of December 31, 2018 and 2017, respectively. This liability was recorded in the other liabilities section on the consolidated statements of financial condition and was calculated using an assumed discount rate of 5.12% in 2018 and 2017.  Under the 2001 Plans and the 2012 Plan, the Company can set aside assets to fund the liability which will be subject to claims of the Company’s creditors upon liquidation of the Company. The Company purchased bank owned life insurance for the purpose of funding this liability. The cash surrender value of the bank owned life insurance for these plans amounted to $11.0 million and $10.8 million at December 31, 2018 and 2017, respectively. An additional $2.5 million of bank owned life insurance was purchased during the fourth quarter of 2016 to fund the increase in liability arising from the amendments to the 2001 and 2012 plans.  The Company’s expense for the 2001 and 2012 Plans was $404,000 for the year ended December 31, 2018 and $338,000 and $406,000 for the years ended December 31, 2017 and 2016, respectively.  2018 Retention Agreement  Effective March 29, 2018, the Company entered into a Retention Agreement with one executive. The agreement provides that the Executive will receive a payment of $1.4 million (the "Normal Retention Payment") provided that the Executive remains continuously employed with the Bank through March 29, 2028 (the "Retention Date"). The Normal Retention Payment will be paid in three equal installments on March 29, 2028, January 2, 2029, and January 2, 2030. If the Executive's employment is terminated without cause or for good reason (as defined in the agreement) prior to the Retention Date, the Executive will receive the vested account balance as set forth in the agreement. In the event that the Executive's employment terminates prior to the Retention Date due to death or disability, the Executive or his beneficiary, as applicable, will generally receive the vested account balance. If the Executive's employment is terminated prior to the Retention Date, and within two years of a change in control (as defined in the agreement), the Executive will receive the Normal Retention Payment in a lump sum payment. The Company had a liability under this plan of $65,000 as of December 31, 2018. This liability was recorded in the other liabilities section on the consolidated statements of financial condition and was calculated using an assumed discount rate of 5.12% in 2018.  Although the agreement is unfunded, the Company purchased $3.0 million of bank owned life insurance during 2018 to fund the increase in liability. The cash surrender value of the bank owned life insurance for this agreement was $3.0 million at December 31, 2018.  The Company’s expense for the 2018 Plan was $65,000 for the year ended December 31, 2018.

Stock-based Compensation [Abstract]
Stock-based Compensation	Note 12 – Stock-based Compensation As of December 31, 2018, the Company had four stock-based compensation plans, which are described below. The compensation cost that has been recorded under salary and benefits expense in the non-interest expense section of the consolidated statements of income for these plans was $ 575,000 , $ 566,000 , and $ 331,000 for the years ended December 31, 2018, 2017 and 2016, respectively. 2006 Stock Option Plan The Company’s 2006 Stock Option Plan (the “Stock Option Plan”), which was approved by the Company’s stockholders, permitted the grant of options to its employees and non-employee directors for up to 297,562 shares of common stock. The Stock Option Plan expired on October 24, 2016, and grants of options can no longer be awarded. Both incentive stock options and non-qualified stock options have been granted under the Stock Option Plan. The exercise price of each stock option equals the market price of the Company’s common stock on the date of grant and an option’s maximum term is ten years. The stock options generally vest over a five year period. A summary of the status of the Stock Option Plan during the year ended December 31, 2018, 2017 and 2016 is presented below:    December 31, 2018 December 31, 2017 December 31, 2016  Options Weighted Average Exercise Price Remaining Contractual Life Options Weighted Average Exercise Price Remaining Contractual Life Options Weighted Average Exercise Price Remaining Contractual Life  Outstanding at beginning of year 82,321 $ 12.98 82,826 $ 12.95 118,087 $ 10.68  Granted - - - - 64,547 14.38  Exercised - - (505) 8.01 (99,808) 11.19  Forfeited - - - - - -  Outstanding at end of period 82,321 $ 12.98 6.4 years 82,321 $ 12.98 7.4 years 82,826 $ 12.95 8.3 years   Options exercisable at end of period 43,591 $ 11.73 6.4 years 30,681 $ 10.61 7.4 years 18,279 $ 7.88 8.3 years   Fair value of options granted $ - $ - $ 2.64  At December 31, 2018, stock options outstanding had an intrinsic value of $ 172,000 and there were no remaining options available for grant under the Stock Option Plan. There were no stock options exercised during the year ended 2018. The intrinsic value of stock options exercised was $4,000 and $218,000 for the years ended December 31, 2017 and 2016, respectively. Compensation expense related to the Stock Option Plan amounted to $ 34,000 for the years ended December 31, 2018 and 2017, and $7,000 for the years ended December 31, 2016. At December 31, 2018, $96,000 of unrecognized compensation cost related to the Stock Option Plan is expected to be recognized over a period of 34 months. 2006 Recognition and Retention Plan The Company’s 2006 Recognition and Retention Plan (“RRP”), which was approved by the Company’s stockholders, permitted the grant of restricted stock awards (“Awards”) to employees and non-employee directors for up to 119,025 shares of common stock. The RRP expired on October 24, 2016, and as of October 24, 2016 all shares permitted under the plan have been granted.  As of December 31, 2018, there were 108,837 shares vested or distributed to eligible participants under the RRP. Compensation expense amounted to $ 89,000 for the years ended December 31, 2018 and 2017, and $70,000 for the year ended December 31, 2016. At December 31, 2018, $ 107,000 of unrecognized compensation cost related to the RRP is expected to be recognized over a period of 34 months. A summary of the status of unvested shares under the RRP for the years ended December 31, 2018, 2017 and 2016 is as follows:    2018 Weighted Average Grant Price (per Share) 2017 Weighted Average Grant Price (per Share) 2016 Weighted Average Grant Price (per Share)  Unvested shares outstanding at beginning of year 17,119 $ 13.06 24,110 $ 12.96 21,397 $ 12.25  Granted - - - - 8,087 14.38  Vested (6,931) 12.75 (6,991) 12.73 (5,374) 12.23  Unvested shares outstanding at end of period 10,188 $ 13.27 17,119 $ 13.06 24,110 $ 12.96  2012 Equity Incentive Plan  The Company’s 2012 Equity Incentive Plan (the “EIP”), which was approved by the Company’s stockholders on May 23, 2012, authorizes the issuance of up to 180,000 shares of common stock pursuant to grants of restricted stock awards and up to 20,000 shares of common stock pursuant to grants of incentive stock options and non-qualified stock options, subject to permitted adjustments for certain corporate transactions. Employees and directors of Lake Shore Bancorp or its subsidiaries are eligible to receive awards under the EIP, except that non-employees may not be granted incentive stock options.  The Board of Directors granted restricted stock awards under the EIP during 2018 as follows:     Grant Date Number of Restricted Stock Awards Vesting Fair Value per Share of Award on Grant Date Awardees   February 7, 2018 5,285 100% on December 14, 2018 $ 17.00 Non-employee directors  April 24, 2018 44 100% on December 14, 2018 16.88 Non-employee director  A summary of the status of unvested restricted stock awards under the EIP for the years ended December 31, 2018, 2017, and 2016 is as follows:    2018 Weighted Average Grant Price (per Share) 2017 Weighted Average Grant Price (per Share) 2016 Weighted Average Grant Price (per Share)  Unvested shares outstanding at beginning of year 42,915 $ 14.40 26,072 $ 12.77 27,769 $ 12.64  Granted 5,329 17.00 27,348 15.90 20,354 13.38  Vested (22,128) 14.00 (9,880) 14.31 (10,230) 12.91  Forfeited (795) 14.85 (625) 13.76 (11,821) 13.37  Unvested shares outstanding at end of period 25,321 $ 15.28 42,915 $ 14.40 26,072 $ 12.77  As of December 31, 2018, there were 53,925 shares of restricted stock vested or distributed to eligible participants under the EIP. Compensation expense related to restricted stock awards under the EIP amounted to $311,000 for the year ended December 31, 2018, $306,000 for the year ended December 31, 2017, and $ 144,000 for the year ended December 31, 2016. During the year ended December 31, 2016, the Company reversed $91,000 of previously accrued compensation expense associated with 10,117 restricted stock awards that were awarded in 2015. Management concluded that it was more likely than not that the performance metric associated with these stock awards could not be achieved, and that the awards would not vest in 2017. At December 31, 2018, $143,000 of unrecognized compensation cost related to unvested awards is expected to be recognized over a period of 12 months.  A summary of the status of stock options under the EIP for the years ended December 31, 2018, 2017, and 2016 is as follows:    December 31, 2018 December 31, 2017 December 31, 2016  Options Exercise Price Remaining Contractual Life Options Exercise Price Remaining Contractual Life Options Exercise Price Remaining Contractual Life  Outstanding at beginning of year 20,000 $ 14.38 20,000 $ 14.38 - $ -  Granted - - - - 20,000 14.38  Exercised - - - - - -  Forfeited - - - - - -  Outstanding at end of period 20,000 $ 14.38 7.8 years 20,000 $ 14.38 8.8 years 20,000 $ 14.38 9.8 years   Options exercisable at end of period 7,997 $ 14.38 7.8 years 3,998 $ 14.38 8.8 years - $ -   Fair value of options granted - - 2.64  At December 31, 2018, stock options outstanding had an intrinsic value of $14,000 and there were no remaining options available for grant under the EIP.

At December 31, 2018, $30,000 of unrecognized compensation cost related to unvested stock options is expected to be recognized over a period of 34 months.  Employee Stock Ownership Plan (“ESOP”) The Company established the ESOP for the benefit of eligible employees of the Company and Bank. All Company and Bank employees meeting certain age and service requirements are eligible to participate in the ESOP. Participants’ benefits become fully vested after five years of service once the employee is eligible to participate in the ESOP. The Company utilized $ 2.6 million of the proceeds of its 2006 stock offering to extend a loan to the ESOP and the ESOP used such proceeds to purchase 238,050 shares of stock on the open market at an average price of $ 10.70 per share, plus commission expenses. As a result of the purchase of shares by the ESOP, total stockholders’ equity of the Company was reduced by $ 2.6 million. As of December 31, 2018, the balance of the loan to the ESOP was $ 1.6 million and the fair value of unallocated shares was $ 2.0 million. As of December 31, 2018, there were 77,874 allocated shares and 134,895 unallocated shares compared to 70,353 allocated shares and 142,830 unallocated shares at December 31, 2017 and 69,333 allocated shares and 150,765 unallocated shares at December 31, 2016. The ESOP compensation expense was $ 130,000 for the year ended December 31, 2018, $126,000 for the year ended December 31, 2017, and $108,000 for the year ended December 31, 2016 based on 7,935 shares earned in each of those years.

Fair Value of Financial Instruments [Abstract]
Fair Value of Financial Instruments	Note 13 - Fair Value of Financial Instruments Management uses its best judgment in estimating the fair value of the Company’s financial instruments; however, there are inherent weaknesses in any estimation technique. Therefore, for substantially all financial instruments, the fair value estimates herein are not necessarily indicative of the amounts the Company could have realized in a sale transaction on the dates indicated. The estimated fair value amounts have been measured as of December 31, 2018 and 2017 and have not been re-evaluated or updated for purposes of these consolidated financial statements subsequent to those respective dates. The estimated fair values of these financial instruments subsequent to the respective reporting dates may be different than the amounts reported here. The measurement of fair value under FASB ASC Topic 820, “Fair Value Measurements and Disclosures” (“ASC Topic 820”) establishes a fair value hierarchy that prioritizes the inputs to valuation methods used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities measurements (Level 1) and the lowest priority to unobservable input measurements (Level 3). The three levels of the fair value hierarchy under ASC Topic 820 are as follows: Level 1: Unadjusted quoted prices in active markets for identical assets or liabilities that the reporting entity can access at the measurement date.  Level 2: Inputs other than quoted prices included in Level 1 that are observable for the asset or liability either directly or indirectly.  Level 3: Unobservable inputs for determining the fair values of assets or liabilities that reflect an entity’s own assumptions about the assumptions that market participants would use in pricing the assets or liabilities.  An asset’s or liability’s level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement.  For assets measured at fair value on a recurring basis, the fair value measurements by level within the fair value hierarchy used at December 31, 2018 and 2017 were as follows:    Fair Value Measurements at December 31, 2018  Quoted Prices in Active Markets for Identical Assets Significant Other Observable Inputs Significant Other Unobservable Inputs  Fair Value (Level 1) (Level 2) (Level 3)  (Dollars in thousands)  Measured at fair value on a recurring basis:  Securities available for sale:  Debt Securities  U.S. Government Agencies $ 1,961 $ 1,961 $ - $ -  Municipal bonds 44,942 - 44,942 -  Mortgage-backed securities:  Collateralized mortgage obligations-private label 27 - 27 -  Collateralized mortgage obligations-government sponsored entities 32,453 - 32,453 -  Government National Mortgage Association 199 - 199 -  Federal National Mortgage Association 2,385 - 2,385 -  Federal Home Loan Mortgage Corporation 3,888 - 3,888 -  Asset-backed securities:  Private label 270 - 270 -  Government sponsored entities 44 - 44 -  Total Debt Securities $ 86,169 $ 1,961 $ 84,208 $ -  Equity Securities 24 - 24 -  Total Securities Available for Sale $ 86,193 $ 1,961 $ 84,232 $ -     Fair Value Measurements at December 31, 2017  Quoted Prices in Active Markets for Identical Assets Significant Other Observable Inputs Significant Other Unobservable Inputs  Fair Value (Level 1) (Level 2) (Level 3)  (Dollars in thousands)  Measured at fair value on a recurring basis:  Securities available for sale:  Debt Securities  U.S. Government Agencies $ 1,987 $ 1,987 $ - $ -  Municipal bonds 45,562 - 45,562 -  Mortgage-backed securities:  Collateralized mortgage obligations-private label 30 - 30 -  Collateralized mortgage obligations-government sponsored entities 27,654 - 27,654 -  Government National Mortgage Association 245 - 245 -  Federal National Mortgage Association 2,929 - 2,929 -  Federal Home Loan Mortgage Corporation 1,553 - 1,553 -  Asset-backed securities:  Private label 344 - - 344  Government sponsored entities 60 - 60 -  Total Debt Securities $ 80,364 $ 1,987 $ 78,033 $ 344  Equity Securities 57 - 57 -  Total Securities Available for Sale $ 80,421 $ 1,987 $ 78,090 $ 344  Any transfers between levels would be recognized as of the actual date of event or change in circumstances that caused the transfer. There were no reclassifications between the Level 1 and Level 2 categories for the years ended December 31, 2018 and 2017. During the year ended December 31, 2018, asset-backed securities – private label were transferred from the Level 3 category to the Level 2 category. These securities were transferred to Level 2 because the Company changed its method of valuing these securities and that method now uses Level 2 inputs. These securities are now valued using Level 2 inputs because the price volatility associated with these securities has been reduced and management considers the quoted market price for these securities to be reasonable.  Level 2 inputs for assets or liabilities measured at fair value on a recurring basis might include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability (such as interest rates, volatilities, prepayment speeds, credit risks, etc.) or inputs that are derived principally from or corroborated by market data by correlation or other means.  The fair value of securities available for sale are determined by obtaining quoted market prices on nationally recognized securities exchanges (Level 1) or matrix pricing (Level 2), which is a mathematical technique used widely in the industry to value debt securities without relying exclusively on quoted market prices for the specific securities, but rather by relying on the securities’ relationship to other benchmark quoted prices. The fair value measurements consider observable data that may include dealer quotes, market spreads, cash flows, the U.S. treasury yield curve, live trading levels, trade execution date, market consensus prepayment speeds, credit information, and the security’ terms and conditions, among other things. Level 2 securities which are fixed income instruments that are not quoted on an exchange, but are traded in active markets, are valued using prices obtained from our custodian, who use third party data service providers. Securities available for sale measured within the Level 3 Category as of December 31, 2017 consisted of private label asset-backed securities.  The following table presents a reconciliation of the securities available for sale measured at fair value on a recurring basis using significant unobservable inputs (Level 3), specifically, asset-backed securities - private label, for the years ended December 31, 2018 and 2017:   2018 2017  (Dollars in thousands)  Beginning Balance $ 344 $ 832  Total gains - realized/unrealized:  Included in earnings - -  Included in other comprehensive loss - 13  Total losses - realized/unrealized: -  Included in earnings - -  Included in other comprehensive loss - (86)  Sales - -  Principal paydowns - (415)  Transfers to (out of) Level 3 (344) -  Ending Balance $ - $ 344  Both observable and unobservable inputs may be used to determine the fair value of assets and liabilities measured on a recurring basis that the Company has classified within the Level 3 category. As a result, any unrealized gains and losses for assets within the Level 3 category may include changes in fair value attributable to both observable (e.g., changes in market interest rates) and unobservable (e.g., changes in unobservable long-dated volatilities) inputs.  The following table presents additional quantitative information about the Level 3 inputs for the asset-backed securities - private label category. The fair values for this category were developed using the discounted cash flow technique with the following unobservable input ranges as of December 31, 2017 (dollars in thousands):    Unobservable Inputs  Security Category Fair Value Loan Type/Collateral Credit Ratings Constant Prepayment Speed (CPR) Probability of Default (Annual Default Rate) Loss Severity   December 31, 2017  Asset-backed securities - private label $ 344 Sub-prime First and Prime Second Lien - Residential Real Estate B- thru D 5 - 12 3.0 - 5.0% 75.0% - 100.0%  At December 31, 2017, Level 3 inputs were determined by the Company’s management using inputs from its third party financial advisor on a quarterly basis. The significant unobservable inputs used in the fair value measurement of the reporting entity’s asset-backed, private label securities are prepayment rates, probability of default and loss severity in the event of default. Significant increases or decreases in any of those inputs in isolation would result in a significantly lower or higher fair value measurement. Generally, a change in the assumption used for the probability of default is accompanied by a directionally similar change in the assumption used for the loss severity and a directionally opposite change in the assumption used for prepayment rates.  In addition to disclosure of the fair value of assets on a recurring basis, ASC Topic 820 requires disclosures for assets and liabilities measured at fair value on a non-recurring basis, such as impaired assets and foreclosed real estate. Loans are generally not recorded at fair value on a recurring basis. Periodically, the Company records non-recurring adjustments to the carrying value of loans based on fair value measurements for partial charge-offs of the uncollectible portions of these loans. Non-recurring adjustments also include certain impairment amounts for collateral-dependent loans calculated as required by ASC Topic 310, “ Receivables – Loan Impairment ,” when establishing the allowance for loan losses. An impaired loan is carried at fair value based on either a recent appraisal less estimated selling costs of underlying collateral or discounted cash flows based on current market conditions.  For assets measured at fair value on a non-recurring basis, the fair value measurements by level within the fair value hierarchy used at December 31, 2018 and 2017 were as follows:   Fair Value Measurements  Quoted Prices in Active Markets for Identical Assets Significant Other Observable Inputs Significant Other Unobservable Inputs  Fair Value (Level 1) (Level 2) (Level 3)  (Dollars in thousands)  Measured at fair value on a non-recurring basis:   At December 31, 2018  Impaired loans $ 252 $ - $ - $ 252  Foreclosed real estate 184 - - 184   At December 31, 2017  Impaired loans $ 35 $ - $ - $ 35  Foreclosed real estate 438 - - 438             The following table presents additional quantitative information about assets measured at fair value on a non-recurring basis and for which the Company has utilized Level 3 inputs to determine fair value:   Quantitative Information about Level 3 Fair Value Measurements  (Dollars in thousands) Fair Value Estimate Valuation Technique Unobservable Input Range  At December 31, 2018  Impaired loans $ 252 Market valuation of underlying collateral (1) Direct Disposal Costs (2) 7.00 - 20.33 %  Foreclosed real estate 184 Market valuation of property (1) Direct Disposal Costs (2) 7.00 - 10.00 %  At December 31, 2017  Impaired loans $ 35 Market valuation of underlying collateral (1) Direct Disposal Costs (2) 7.00%  Foreclosed real estate 438 Market valuation of property (1) Direct Disposal Costs (2) 7.00 - 16.80 %  (1) Fair value is generally determined through independent third-party appraisals of the underlying collateral, which generally includes various Level 3 inputs which are not observable . (2) The fair value basis of impaired loans and foreclosed real estate may be adjusted to reflect management estimates of disposal costs including, but not necessarily limited to, real estate brokerage commissions, legal fees, and delinquent property taxes.  At December 31, 2018, impaired loans valued using Level 3 inputs had a carrying amount of $282,000 and valuation allowances of $30,000 . By comparison, at December 31, 2017, impaired loans valued using Level 3 inputs had a carrying amount of $35,000 and no valuation allowances.  Once a loan is determined to be impaired, the fair value of the loan continues to be evaluated based upon the market value of the underlying collateral securing the loan or by using a discounted future cash flow method if the loan is not collateral dependent. At December 31, 2018, impaired loans whose carrying amount was written down utilizing Level 3 inputs during the year ended December 31, 2018 comprised of one loan with a fair value of $226,000 and resulted in an additional provision for loan loss of $ 30,000 .  At December 31, 2018, foreclosed real estate valued using Level 3 inputs had a carrying amount of $ 260,000 and valuation allowances of $76,000 . By comparison at December 31, 2017, foreclosed real estate valued using Level 3 inputs had a carrying amount of $557,000 and valuation allowances of $119,000 .  Once a loan is foreclosed, the fair value of the real estate owned continues to be evaluated based upon the market value of the repossessed real estate originally securing the loan. At December 31, 2018, foreclosed real estate whose carrying value was written down utilizing Level 3 inputs during the year ended December 31, 2018 comprised of two properties with a fair value of $ 203,000 and resulted in additional provision for loan losses of $20,000 and subsequent write-downs recorded in non-interest expense of $40,000 . At December 31, 2017, foreclosed real estate whose carrying value was written down utilizing Level 3 inputs during the year ended December 31, 2017 comprised of two properties with a fair value of $ 399,000 and resulted in an additional provision for loan losses of $75,000 and subsequent write-downs recorded in non-interest expense of $15,000 .  The carrying amount and estimated fair value of the Company’s financial instruments, whether carried at cost or fair value, are as follows:     Fair Value Measurements at December 31, 2018  Carrying Estimated Quoted Prices in Active Markets for Identical Assets Significant Other Observable Inputs Significant Other Unobservable Inputs  Amount Fair Value (Level 1) (Level 2) (Level 3)  (Dollars in thousands)  Financial assets:  Cash and cash equivalents $ 30,751 $ 30,751 $ 30,751 $ - $ -  Securities available for sale 86,193 86,193 1,961 84,232 -  Federal Home Loan Bank stock 1,545 1,545 - 1,545 -  Loans receivable, net 392,471 376,774 - - 376,774  Accrued interest receivable 1,913 1,913 - 1,913 -  Financial liabilities:  Deposits 432,458 435,547 - 435,547 -  Long-term debt 24,650 24,292 - 24,292 -  Accrued interest payable 63 63 - 63 -  Off-balance-sheet financial instruments - - - - -      Fair Value Measurements at December 31, 2017  Carrying Estimated Quoted Prices in Active Markets for Identical Assets Significant Other Observable Inputs Significant Other Unobservable Inputs  Amount Fair Value (Level 1) (Level 2) (Level 3)  (Dollars in thousands)  Financial assets:  Cash and cash equivalents $ 40,913 $ 40,913 $ 40,913 $ - $ -  Securities available for sale 80,421 80,421 1,987 78,090 344  Federal Home Loan Bank stock 1,631 1,631 - 1,631 -  Loans receivable, net 365,063 356,275 - - 356,275  Accrued interest receivable 1,801 1,801 - 1,801 -  Financial liabilities:  Deposits 405,153 408,348 - 408,348 -  Long-term debt 26,950 26,634 - 26,634 -  Accrued interest payable 57 57 - 57 -  Off-balance-sheet financial instruments - - - - - 

Regulatory Capital Requirements

Regulatory Capital Requirements [Abstract]
Regulatory Capital Requirements	Note 14 - Regulatory Capital Requirements Lake Shore Savings Bank is subject to various regulatory capital requirements administered by federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory and possible additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the Company’s consolidated financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Bank must meet specific capital guidelines that involve quantitative measures of the Bank’s assets, liabilities, and certain off-balance-sheet items as calculated under regulatory accounting practices. The Bank’s capital amounts and classifications are also subject to qualitative judgments by the regulators about components, risk-weightings and other factors. As of January 1, 2015, new federal regulations that substantially revised the minimum capital standards and the method for calculating risk-weighted assets became applicable to the Company. The revised regulations are now consistent with the Basel III regulatory capital reforms and changes required by the Dodd-Frank Act. The revised regulations established a new common equity Tier 1 (“CET1”) minimum capital requirement, increased the minimum Tier 1 capital ratio, changed the risk weight of certain assets for purposes of calculating the risk-based capital ratios, created an additional capital conservation buffer over the required capital ratios and changed what qualifies as capital for purposes of meeting these various capital requirements. As of January 2016, failure to maintain the required capital conservation buffer limits the ability of the Bank to pay dividends or discretionary bonuses. The Company is exempt from consolidated capital requirements as those requirements do not apply to certain small savings and loan holding companies or bank holding companies with assets under $1 billion. Under the revised capital requirements, the minimum capital ratios are: (1) a CET1 capital ratio of 4.5% of risk-weighted assets; (2) a Tier 1 capital ratio of 6.0% of risk-weighted assets; (3) a total capital ratio of 8% of risk-weighted assets; and (4) a leverage ratio of 4.0%. CET1 capital generally consists of common stock and retained earnings, subject to applicable regulatory adjustments and deductions. There are a number of changes in what constitutes regulatory capital, some of which are subject to transition periods. These changes include the phasing-out of certain instruments as qualifying capital. The Bank does not use any of these instruments. Under the new requirements for total capital, Tier 2 capital is no longer limited to the amount of Tier 1 capital included in total capital. Mortgage servicing rights, certain deferred tax assets and investments in unconsolidated subsidiaries over designated percentages of CET1 will be deducted from capital. The Bank has elected to permanently opt-out of the inclusion of accumulated other comprehensive income in the Bank’s capital calculations, as permitted by the regulations. This opt-out will reduce the impact of market volatility on the Bank’s investment portfolio for purposes of calculating the Bank’s regulatory capital. The new requirements also include changes in the risk-weights of assets to better reflect credit risk and other risk exposures. These include a 150% risk weight (increased from 100%) for certain high volatility commercial real estate facilities that finance the acquisition, development or construction of real property and for all loans (except one- to four-family real estate loans) that are 90 days past due or otherwise in non-accrual status; a 20% (increased from 0%) credit conversion factor for the unused portion of a commitment with an original maturity of one year or less that is not unconditionally cancellable; a 250% risk weight (increased from 100%) for mortgage servicing and deferred tax assets that are not deducted from capital; and increased risk weights (0% to 600%) for equity exposures. In addition to the minimum CET1, Tier 1 and total capital ratios, the Bank will have to maintain a capital conservation buffer consisting of additional CET1 capital greater than 2.5% of risk-weighted assets above the required minimum levels in order to avoid limitations on paying dividends and discretionary bonuses. This new capital conservation buffer requirement has a phase-in period which began in January 2016 at 0.625% of risk-weighted assets and increases each year until full implementation in January 2019. The OCC’s prompt corrective action standards changed effective January 1, 2015. Under the new standards, in order to be considered well-capitalized, the Bank must have a CET1 ratio of 6.5% (new), a Tier 1 ratio of 8.0% (increased from 6.0%), a total risk-based capital ratio of 10.0% (unchanged) and a leverage ratio of 5.0% (unchanged). As of December 31, 2018, the Bank met all of the new requirements, including the full capital conservation buffer that will be required by January 2019. The most recent notification from the Federal banking agencies categorized the Bank as well capitalized at December 31, 2018 under the regulatory framework for prompt corrective action. To be categorized as well capitalized, the Bank must maintain minimum ratios as set forth in the following table. There are no conditions or events since that notification that management believes have changed the Bank’s category. The Bank’s actual capital amounts and ratios at December 31, 2018 and 2017 are presented in the following table:   Actual Minimum Ratio For Capital Adequacy Purposes Minimum Ratio To Be Well Capitalized Under Prompt Corrective Action Provisions Capital Conservation Buffer  Amount Ratio Amount Ratio Amount Ratio Actual Required  At December 31, 2018  Total capital (to risk-weighted assets) $ 79,662 20.59 % 30,948 8.00 % 38,685 10.00 % 12.592 % 1.875 %  Tier 1 capital (to risk-weighted assets) 76,218 19.70 % 23,211 6.00 % 30,948 8.00 % 13.702 % 1.875 %  CET 1 capital (to risk-weighted assets) 76,218 19.70 % 17,408 4.50 % 25,145 6.50 % 15.202 % 1.875 %  Tier 1 Leverage (to adjusted total assets) 76,218 13.99 % 21,785 4.00 % 27,232 5.00 % 9.994 % 1.875 %  At December 31, 2017  Total capital (to risk-weighted assets) $ 77,220 21.75 % 28,403 8.00 % 35,503 10.00 % 13.750 % 1.250 %  Tier 1 capital (to risk-weighted assets) 73,925 20.82 % 21,302 6.00 % 28,403 8.00 % 14.822 % 1.250 %  CET 1 capital (to risk-weighted assets) 73,925 20.82 % 15,977 4.50 % 23,077 6.50 % 16.322 % 1.250 %  Tier 1 Leverage (to adjusted total assets) 73,925 14.40 % 20,537 4.00 % 25,671 5.00 % 10.398 % 1.250 %   Following is a reconciliation of Lake Shore Savings Bank’s consolidated GAAP capital to regulatory Tier 1 and CET 1 capital, as well as to Total capital at December 31, 2018 and December 31, 2017:    December 31,  2018 2017  (Dollars in thousands)   GAAP (Equity) Capital: $ 76,347 $ 74,745  Plus: -  Unrealized gains on available-for-sale securities, net of tax (129) (791)  Less:  Additional tier 1 capital deductions - (29)   Tier 1 Capital and CET1 Capital 76,218 73,925   Plus:  Allowance for loan losses 3,448 3,283  Unrealized gains on available-for-sale securities includible in regulatory capital - 16  Less:  Other investments required to be deducted (4) (4)   Total Regulatory Capital $ 79,662 $ 77,220

Earnings per Share [Abstract]
Earnings per Share	Note 15 – Earnings per Share Earnings per share was calculated for the years ended December 31, 2018, 2017 and 2016, respectively. Basic earnings per share is based upon the weighted average number of common shares outstanding, exclusive of unearned shares held by the ESOP, RRP and EIP. Diluted earnings per share is based upon the weighted average number of common shares outstanding and common share equivalents that would arise from the exercise of dilutive securities. Stock options are regarded as potential common stock and are considered in the diluted earnings per share calculations to the extent they would be dilutive and computed using the treasury stock method.  The calculated basic and diluted earnings per share are as follows:    Years Ended December 31,  2018 2017 2016  Numerator – net income $ 4,000,000 $ 3,378,000 $ 3,515,000  Denominator:  Basic weighted average shares outstanding 6,075,798 6,110,365 6,014,973  Increase in weighted average shares outstanding due to:  Stock options 9,902 8,930 7,676  Diluted weighted average shares outstanding (1) 6,085,700 6,119,295 6,022,649   Earnings per share:  Basic $ 0.66 $ 0.55 $ 0.58  Diluted $ 0.66 $ 0.55 $ 0.58  (1) Stock options to purchase 64,547 shares under the Stock Option Plan and 20,000 shares under the EIP at $14.38 were outstanding during 2017 and 2016, but were not included in the calculation of diluted earnings per share because to do so would have been anti-dilutive.

Commitments to Extend Credit [Abstract]
Commitments to Extend Credit	Note 16 – Commitments to Extend Credit The Company has commitments to extend credit with off-balance sheet risk in the normal course of business to meet the financing needs of its customers. Such commitments involve, to varying degrees, elements of credit and interest rate risk in excess of the amount recognized in the consolidated statements of financial condition. The Company’s exposure to credit loss is represented by the contractual amount of these commitments. There were no loss reserves associated with these commitments at December 31, 2018 and 2017. The Company follows the same credit policies in making commitments as it does for on-balance sheet instruments. The following commitments to extend credit were outstanding as of the dates specified:   Contract Amount  December 31, December 31,  2018 2017  (Dollars in thousands)   Commitments to grant loans $ 41,901 $ 16,426  Unfunded commitments under lines of credit $ 52,371 $ 41,395  Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses. The commitments for lines of credit may expire without being drawn upon. Therefore, the total commitment amounts do not necessarily represent future cash requirements. The amount of collateral obtained, if it is deemed necessary by the Company, is based on management’s credit evaluation of the customer.

Revenue Recognition

Revenue Recognition [Abstract]
Revenue Recognition	Note 21 – Revenue Recognition  As of January 1, 2018, the Company adopted FASB ASU 2014-09 “Revenue from Contracts with Customers (Topic 606)” (“ASU 2014-09”) for non-interest revenue streams. The Company has elected to apply ASU 2014-09 using the modified retrospective method. The implementation of the new standard did not have a material impact on the measurement or recognition of revenue; and as such, a cumulative effect adjustment to retained earnings was not deemed necessary under the modified retrospective implementation method. The adoption of ASU 2014-09 did, however, require additional disclosures.  The Company’s non-interest revenue streams primarily result from services it provides to its deposit customers. When a customer makes a deposit, the Company records a liability under ASC 405 “Liabilities” because the Company has an obligation to deliver cash to its customer on demand. A contract between the Company and a deposit account customer is typically documented in writing and is often terminable at will by the customer alone or by both the customer and the Company without penalty. The term of a deposit contract between a customer and the Company will likely be day-to-day or minute-to-minute, and the termination clause is likely similar to a renewal right where each day or minute represents the renewal of the contract. The Company generally fully satisfies its performance obligations on its contracts with customers as services are rendered and the transaction prices are typically fixed; charged either on a periodic basis or based on activity. Because performance obligations are satisfied as services are rendered and the transaction prices are fixed, there is little judgment involved in applying Topic 606 that significantly affects the determination of the amount and timing of revenue from contracts with customers. The Company’s primary non-interest revenue streams within the scope of ASU 2014-09 are described in further detail below. The Company has no material unsatisfied performance obligations as of December 31, 2018.  Service Charges on Deposit Accounts Service charges and fees on deposit accounts consist of transaction-based fees, account maintenance fees, and overdraft service fees for various retail and business deposit customers. Transaction-based fees, such as stop payment charges, are recognized at the time the Company fulfills the customer’s request. Account maintenance fees, which relate primarily to monthly maintenance, are earned over the course of a month, representing the period over which the Company satisfies the performance obligation. Overdraft fees are recognized at the point in time that the overdraft occurs. Service charges on deposits are withdrawn directly from the customer’s account balance.  Fees, Interchange Income, and Other Service Charges Fees, interchange income, and other service charges are primarily comprised of debit card income, ATM fees, merchant services income and other service charges. Debit card income is primarily comprised of interchange fees earned whenever the Company’s debit cards are used to purchase goods or services from a merchant via a card payment network, such as MasterCard. Interchange fees from cardholder transactions represent a percentage of the underlying transaction value. ATM fees are comprised of fees earned whenever a Company’s ATM or debit card is used at a non-Company ATM or a non-Company cardholder uses a Company ATM. ATM fees represent a fixed fee for the convenience to cardholders for accessibility of funds. Merchant services income mainly represents fees charged to merchants serviced by a third party vendor under contract with the Company for debit or credit card processing, and represents a percentage of the underlying transaction value. Other service charges include revenue from services provided to our retail or business customers, which may include fees for wire transfer processing, bill pay services, cashier’s checks and other services. The Company’s performance obligation for fees, interchange income and other service charges are largely satisfied, and related revenue recognized, when the services are rendered or upon completion. Payment is typically immediately or in the following month.  Other Other non-interest income consists of safe deposit rental fees. Safe deposit box rental fees are charged to the customer on an annual basis and recognized upon receipt of payment. The Company determined that since rentals and renewals occur fairly consistently over time, revenue is recognized on a basis consistent with the duration of the performance obligation.  Gain/Losses on Sale of OREO The Company records a gain or loss from the sale of other real estate owned (“OREO”) when control of the property transfers to the buyer, which generally occurs at the time of an executed deed. When the Company finances the sale of OREO to the buyer, the Company assesses whether the buyer is committed to perform their obligations under the contract and whether collectability of the transaction price is probable. Once these criteria are met, the OREO asset is derecognized and the gain or loss on sale is recorded upon the transfer of control of the property to the buyer. In determining the gain or loss on the sale, the Company adjusts the transaction price and related gain (loss) on sale if a significant financing component is present. Gains (losses) on the sale of OREO are generally recorded in non-interest expense on the consolidated statement of income as an offset to OREO expenses. During the year ended December 31, 2018, the Company financed the sale of an OREO property to a buyer. After assessing the applicable criteria under ASU 2014-09, the Company recognized a $33,000 gain on sale of the property. There were no sales of OREO during the year ended December 31, 2017 where the Company financed the sale of the property. Contract Balances The Company’s non-interest revenue streams are largely based on transactional activity. Consideration is often received immediately or shortly after the Company satisfies its performance obligation and revenue is recognized. The Company does not typically enter into long-term revenue contracts with customers, and therefore, does not experience significant contract balances. As of December 31, 2018 and 2017, the Company did not have any significant contract balances.  The following presents non-interest income, segregated by revenue streams in-scope and out-of-scope of Topic 606, for the years ended December 31, 2018, 2017 and 2016:      For the years ended December 31,  2018 2017 2016  (Dollars in thousands)  Non-Interest Income  In-Scope of Topic 606:  Service charges on deposit accounts $ 880 $ 912 $ 922  Fees, interchange income and other service charges 804 741 716  Other 40 39 40  Non-interest Income (in-scope of Topic 606) 1,724 1,692 1,678  Non-interest Income (out of scope of Topic 606) 750 963 2,392  Total Non-Interest Income $ 2,474 $ 2,655 $ 4,070

Subsequent Events [Abstract]
Subsequent Events	Note 22 – Subsequent Events  On February 6, 2019, the Board of Directors declared a quarterly cash dividend of $0.12 per share on the Company’s common stock, payable on March 15, 2019 to shareholders of record as of February 21, 2019 . Lake Shore, MHC, which holds 3,636,875 shares, or approximately 60.6% of the Company’s total outstanding stock as of the record date, elected to waive its right to receive this cash dividend of approximately $436,000 . On February 6, 2019, a special meeting of the MHC members (i.e., Lake Shore Savings Bank depositors) was held to vote on a proposal to authorize the MHC to waive its right to receive dividends aggregating up to $0.48 per share that may be declared by the Company in the 12 months subsequent to the approval by members (in accordance with the regulation of the Board of Governors of the Federal Reserve System). At the special meeting, a majority of the eligible member votes of the MHC approved the waiver of the receipt of dividends on shares owned by the MHC. Lake Shore, MHC submitted the results of this vote along with other information to the Federal Reserve Board in order to obtain their non-objection of the dividend waiver. As of March 7, 2019, Lake Shore, MHC received notice of the non-objection of the Federal Reserve Bank of Philadelphia to waive its right to receive dividends paid by the Company during the twelve months ending February 6, 2020, aggregating up to $0.48 per share. The MHC waived $1.5 million of dividends during the year ended December 31, 2018. Cumulatively, Lake Shore, MHC has waived approximately $10.8 million of cash dividends as of December 31, 2018. The dividends waived by Lake Shore, MHC are considered a restriction on the retained earnings of the Company.

Organization and Nature of Operations [Abstract]
Organizational Structure	Organizational Structure  Lake Shore Bancorp, Inc. (the “Company,” “us,” “our,” or “we”) and the parent mutual holding company, Lake Shore, MHC (the “MHC”) were formed on April 3, 2006 to serve as the stock holding companies for Lake Shore Savings Bank (the “Bank”) as part of the Bank’s conversion and reorganization from a New York State chartered mutual savings and loan association to the federal mutual holding company form of organization.  The MHC, whose activity is not included in these consolidated financial statements, held 3,636,875 shares, or 60.6 % of the Company’s outstanding common stock as of December 31, 2018.  Charter  Lake Shore Bancorp, Inc. and the parent mutual holding company, Lake Shore, MHC are federally chartered and regulated by the Federal Reserve Board. Lake Shore Savings Bank, subsidiary of Lake Shore Bancorp, Inc., is a federally chartered savings bank and regulated by the Office of the Comptroller of the Currency (the “OCC”).  Regulations of the Board of Governors of the Federal Reserve System (the “Federal Reserve”) prohibit the waiver of dividends by the MHC unless the waiver has been approved by its members, consisting of depositors of the Bank. The MHC held a special meeting on February 6, 2019 of its members to vote on a proposal to authorize the MHC to waive its right to receive dividends aggregating up to $ 0. 48 per share that may be declared by the Company in the twelve months subsequent to the approval of the proposal by members. At the special meeting, a majority of the eligible member votes of the MHC approved the waiver of the receipt of dividends on shares owned by the MHC. Lake Shore, MHC submitted the results of this vote along with other information to the Federal Reserve for final approval of the dividend waiver. As of March 7, 2019, Lake Shore, MHC received notice of the non-objection of the Federal Reserve Board to waive its right to receive dividends paid by the Company during the twelve months ending February 6, 2020. In prior periods, the MHC elected to waive its right to receive cash dividends upon receipt of the non-objection of the Federal Reserve Board. The waiving of dividends by the MHC will increase Company resources available for stock repurchases, payment of dividends to minority stockholders, and investments. As of December 31, 2018, the MHC elected to waive approximately $ 10.8 million on a cumulative basis. The dividends waived by the MHC are considered a restriction on the retained earnings of the Company.  Nature of Business  The Company’s primary business is the ownership and operation of its subsidiary, the Bank. The Bank is engaged primarily in the business of retail banking through eleven branch offices located in Erie and Chautauqua Counties of New York State. Its primary deposit products are checking, savings and term certificate accounts and its primary lending products are residential mortgages and commercial real estate loans.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policy)	12 Months Ended

Summary of Significant Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The consolidated financial statements include the accounts of the Company and the Bank. All material inter-company accounts and transactions have been eliminated. The accompanying consolidated financial statements have been prepared in conformity with generally accepted accounting principles in the United States of America (“GAAP”). 
Use of Estimates	Use of Estimates To prepare these consolidated financial statements in conformity with GAAP, management of the Company made a number of estimates and assumptions relating to the reporting of assets and liabilities, the reporting of revenue and expenses and notes to the consolidated financial statements. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for loan losses, securities valuation estimates, evaluation of impairment of securities, income taxes and deferred compensation liabilities.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents include cash on hand, amounts due from banks, interest earning deposits at other financial institutions and overnight federal funds sold which are generally sold for one to three-day periods.
Investment Securities	Investment Securities All investment securities are classified as available for sale and are carried at fair value with unrealized gains and losses, net of the related deferred income tax effect, excluded from earnings and reported as a separate component of accumulated other comprehensive income until realized. Realized gains and losses are determined using the specific identification method. Declines in the fair value of available for sale securities are evaluated for other-than-temporary impairment (“OTTI”) on a quarterly basis. Impairment is assessed at the individual security level. This assessment considers factors such as the severity, length of time and anticipated recovery period of the impairment, recent events specific to the issuer, including investment downgrades by rating agencies and economic conditions of its industry, and the issuer’s financial condition, capital strength, the presence of credit enhancements, if any, and near-term prospects. The Company also considers its intent and ability to retain the security for a period of time sufficient to allow for a recovery in fair value, or until maturity. The assessment of a security’s ability to recover any decline in fair value, the ability of the issuer to meet contractual obligations, and the Company’s intent and ability to retain the security require considerable judgment. All securities are reviewed for OTTI under the guidance of the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 320, “ Investments - Debt and Equity Securities ” (“ASC 320”). When impairment of a debt security is considered other-than-temporary, the amount of OTTI recorded as a loss within non-interest income and thereby recognized in earnings depends on whether the Company intends to sell the security or whether it is more likely than not that the Company will be required to sell the security before recovery of its amortized cost basis. If the Company intends to (has decided to) sell the debt security or more likely than not will be required to sell the security before recovery of its amortized cost basis, OTTI is recognized in earnings equal to the entire difference between the investment’s amortized cost basis and its fair value. If the Company does not intend to sell the debt security and it is not more likely than not the Company will be required to sell the security before recovery of its amortized cost basis, OTTI is separated into the amount representing credit loss and the amount related to all other market factors. The amount related to credit loss is recognized against earnings. The amount related to other market factors is recognized in other comprehensive income, net of applicable taxes. For equity securities, the entire amount of OTTI is recognized in earnings.
Federal Home Loan Bank Stock	Federal Home Loan Bank Stock Federal law requires a member institution of the Federal Home Loan Bank (“FHLB”) system to hold restricted stock of its district Federal Home Loan Bank according to a predetermined formula. This stock is restricted in that it can only be sold to the FHLB or to another member institution and all sales of FHLB stock must be at par. As a result of these restrictions, FHLB stock is carried at cost.
Loans Receivable	Loans Receivable Loans receivable that management has the intent and ability to hold until maturity or payoff are stated at their outstanding unpaid principal balances, net of allowance for loan losses and any deferred fees and costs. Interest income is accrued on the unpaid principal balance. Loan origination fees and costs are deferred and recognized as an adjustment of the yield (interest income) of the related loans. The Company is generally amortizing these amounts over the contractual life of the loan. Management considers a loan to be in delinquency status when the contractual payment of principal or interest has become greater than 30 days past due. The accrual of interest is generally discontinued when the contractual payment of principal or interest has become 90 days past due or management has serious doubts about further collectability of principal or interest, even though the loan is currently performing. A loan may remain on accrual status if it is in the process of collection and is either guaranteed or well secured. When a loan is placed on non-accrual status, unpaid interest credited to income is reversed in the current year. Interest received on non-accrual loans generally is either applied against principal or reported as interest income, according to management’s judgment as to the collectability of principal. Generally, loans are restored to accrual status when the obligation is brought current, has performed in accordance with the contractual terms for a reasonable period of time, and the ultimate collectability of the total contractual principal and interest is no longer in doubt.
Allowance for Loan Losses	Allowance for Loan Losses The allowance for loan losses is established through provisions for loan losses charged against income. Loans deemed to be uncollectible are charged against the allowance for loan losses, and subsequent recoveries, if any, are credited to the allowance. Management estimates the allowance for loan losses pursuant to FASB ASC Topic 450, “Contingencies” (“ASC 450”), and FASB ASC Topic 310, “Receivables” (“ASC 310”). Commercial and commercial real estate loans that are considered impaired as defined in ASC 310 are reviewed individually to assess the likelihood and severity of loss exposure. A loan is considered impaired when, based on current information and events, it is probable that the Company will be unable to collect the scheduled payments of principal and interest when due according to the contractual terms of the loan agreement. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis. Factors considered by management in determining impairment include payment status, collateral value, cash flow and the probability of collecting scheduled principal and interest payments when due. Loans subject to individual review are, where appropriate, reserved for according to the present value of expected future cash flows available to repay the loan or the estimated fair value less estimated selling costs of the collateral, if the loan is collateral dependent. Commercial loans excluded from individual assessment, as well as smaller balance homogeneous loans, such as consumer, residential real estate and home equity loans, are evaluated for loss exposure under ASC 450 based upon historical loss rates for each of these categories of loans, adjusted for qualitative factors. The Company does not separately identify individual consumer, home equity, or residential real estate loans for impairment disclosure, unless the loan has been modified as a troubled debt restructuring. The Company records cash receipts on impaired loans that are non-performing as a reduction to principal before applying amounts to interest or late charges unless specifically directed otherwise by the Bankruptcy Court. The Company may continue to recognize interest income on impaired loans where there is no confirmed loss. Loans may be periodically modified in a troubled debt restructuring (“TDR”) to make concessions to help a borrower remain current on the loan and/or to avoid foreclosure, in accordance with FASB Accounting Standard Update (“ASU”) 2012-02, “Receivables (“Subtopic 310”): A Creditor’s Determination of Whether a Restructuring is a Troubled Debt Restructuring” (“ASU 2012-02”). Generally, we do not forgive principal or interest on a loan or modify the interest rate on loans that are below market rates. When we modify loans in a TDR, we evaluate any possible impairment similar to other impaired loans. If we determine that the value of a modified loan is less than the recorded investment in the loan, impairment is recognized through a specific allowance estimate or charge-off to the allowance. The allowance for loan losses is maintained at a level to provide for losses that are inherent within the loan portfolio. This evaluation is inherently subjective as it requires material estimates that may be susceptible to significant change, including the amounts and timing of future cash flows expected to be received on impaired loans. The allowance consists of specific, general and unallocated components. The specific component relates to loans that are classified as either special mention, doubtful, substandard or loss. For such loans that are also classified as impaired, an allowance is established when the discounted cash flows (or collateral value or observable market price) of the impaired loan is lower than the carrying value for that loan. The general component covers non-classified loans and is based on historical loss experience adjusted for qualitative factors. An unallocated component is maintained to cover uncertainties that could affect management’s estimate of probable losses. The unallocated component of the allowance reflects the margin of imprecision inherent in the underlying assumptions used in the methodologies for estimating specific and general losses in the portfolio.
Premises and Equipment	Premises and Equipment Land is carried at cost. Buildings, improvements, furniture and equipment are carried at cost, net of accumulated depreciation. Depreciation is computed on the straight-line basis over the estimated useful lives of assets (generally thirty-nine years for buildings and three to fifteen years for furniture and equipment). Leasehold improvements are amortized on the straight-line method over the lesser of the life of the improvements or the lease term. Maintenance and repairs are charged to expense as incurred, while major improvements are capitalized and amortized to operating expense over the identified useful life.
Transfers of Financial Assets	Transfers of Financial Assets Transfers of financial assets are accounted for as sales, when control over the assets has been surrendered. Control over transferred assets is deemed to be surrendered when (1) the assets have been isolated from the Company, (2) the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and (3) the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity.
Foreclosed Real Estate	Foreclosed Real Estate Foreclosed real estate consists of property acquired in settlement of loans which is carried at its fair value less estimated selling costs. Write-downs from cost to fair value less estimated selling costs are recorded at the date of acquisition or repossession and are charged to the allowance for loan losses. Subsequent write-downs to fair value, net of estimated selling costs, are recorded in non-interest expense along with direct operating expenses. Gains or losses not previously recognized, resulting from the sale of foreclosed assets are recognized in non-interest expense on the date of sale. Foreclosed real estate was $678,000 and $435,000 at December 31, 2018 and 2017, respectively, and was included as a component of other assets in the consolidated statement of financial condition. Proceeds from the sale of foreclosed real estate for the years ended December 31, 2018, 2017 and 2016 were $1.5 million , $331,000 , and $619,000 , respectively. This resulted in a net gain on sale of $44,000 , $8,000 and $9,000 for the years ended December 31, 2018, 2017 and 2016, respectively, and was included as a component of other non-interest expenses in the consolidated statement of income.
Bank Owned Life Insurance	Bank Owned Life Insurance The Company invests in bank owned life insurance (“BOLI”) as a source of funding for employee benefit obligations. BOLI involves the purchase of life insurance by the Company on a chosen group of employees. The Company is the owner and beneficiary of the policies. This life insurance investment is carried at the cash surrender value of the underlying policies. Income from the increase in the cash surrender value of the underlying policies is included in non-interest income in the consolidated statements of income .
Advertising Costs	Advertising Costs The Company follows the policy of charging the costs of advertising to expense as incurred. Total advertising expense for the years ended December 31, 2018, 2017 and 2016 was $606,000 , $596,000 , and $536,000 , respectively.
Income Taxes	Income Taxes The Company files a consolidated federal income tax return. The provision for federal and state income taxes is based on income reported on the consolidated financial statements, rather than the amounts reported on the respective income tax returns. Deferred taxes are recorded using the liability method whereby deferred tax assets are recognized for deductible temporary differences and deferred tax liabilities are recognized for taxable temporary differences. Temporary differences are the differences between the reported amounts of assets and liabilities and their tax basis. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion of the deferred tax assets will not be realized. Deferred tax assets and liabilities are adjusted for the effects of changes in tax laws and rates on the date of enactment and the effect of a change in tax rates is recognized in income at that time. In the fourth quarter of 2017, the Tax Cuts and Jobs Act (the “Tax Act”) was signed into law which required the deferred tax assets and liabilities to be revalued using the 21% federal tax rate enacted for tax years beginning after December 31, 2017 from the previous valuation under the prior federal tax rate of 34% . The effect of the revaluation was $262,000 and was recorded in the fourth quarter 2017 tax provision. Refer to Note 10 for more information on the impact of the Tax Act. The Company makes certain estimates and judgments in determining income tax expense for financial statement purposes. These estimates and judgments are applied in the calculation of certain tax credits and in the calculation of deferred income tax expense or benefit associated with certain deferred tax assets and liabilities. Significant changes to these estimates may result in an increase or decrease to the Company’s tax provision in a subsequent period. The Company recognizes interest and/or penalties related to income tax matters in income tax expense. The Company periodically reviews its tax positions and applies a “more likely than not” recognition threshold for all tax uncertainties. The amount recognized is the largest amount of tax benefit that is greater than 50% likely of being realized on examination. For tax positions not meeting the “more likely than not” test, no tax benefit is recorded.
Employee Stock Ownership Plan (“ESOP”)	Employee Stock Ownership Plan (“ESOP”) Compensation expense is recognized based on the current market price of shares committed to be released to employees. All shares released and committed to be released are deemed outstanding for purposes of earnings per share calculations. Dividends declared and paid on allocated shares held by the ESOP are charged to retained earnings. The value of unearned shares to be allocated to ESOP participants for future services not yet performed is reflected as a reduction of stockholders’ equity. Dividends declared on unallocated shares held by the ESOP are recorded as a reduction of the ESOP’s loan payment to the Company.
Stock Compensation Plans	Stock Compensation Plans At December 31, 2018, the Company had stock-based employee and non-employee compensation plans, which are described more fully in Note 12. The Company accounts for these plans under FASB ASC Topic 718 “ Compensation – Stock Compensation ” (“ASC Topic 718”). The Company accounts for the plans using a fair value-based method, which measures compensation cost at the grant date based on the fair value of the award. Compensation is then recognized over the service period, which is usually the vesting period. The fair value of stock option grants are estimated on the date of grant using the Black-Scholes options-pricing model. Common shares are issued from the Company’s authorized common shares when a share option is exercised. Common shares awarded as restricted stock are expensed based on the fair market value at the grant date. The stock option plan, restricted stock plan and equity incentive plan expenses are recognized in salaries and employee benefits expense on the consolidated statement of income.
Earnings per Common Share	Earnings per Common Share Basic earnings per share is computed by dividing net income by the weighted average number of common shares outstanding, less unallocated shares held by the Company’s ESOP, 2006 Recognition and Retention Plan (“RRP”) and 2012 Equity Incentive Plan (“EIP”), during the period. Diluted earnings per share reflects additional common shares that would have been outstanding if dilutive potential common shares had been issued, as well as any adjustment to income that would result from the assumed conversion. Potential common shares that may be issued by the Company relate solely to outstanding stock options and restricted stock awards, and are determined using the treasury stock method.
Off-Balance Sheet Credit Related Financial Instruments	Off-Balance Sheet Credit Related Financial Instruments In the ordinary course of business, the Company has entered into commitments to extend credit. Such commitments are recorded in the consolidated statement of financial condition when they are funded.
Comprehensive Income	Comprehensive Income Accounting principles generally require that recognized revenue, expenses, gains, and losses be included in net income. Although certain changes in assets and liabilities, such as unrealized gains and losses on available for sale securities and OTTI related to non-credit factors, are reported as a separate component of the stockholders’ equity section of the consolidated statement of financial condition, such items, along with net income, are components of comprehensive income.
Restrictions on Cash and Due from Banks	Restrictions on Cash and Due from Banks The Company is required to maintain reserve funds in cash or on deposit with the Federal Reserve Bank. The required reserve at December 31, 2018 and 2017 was $2,790,000 and $2,738,000 , respectively.
Subsequent Events	Subsequent Events The Company evaluated events occurring subsequent to December 31, 2018 through the date the consolidated financial statements are being issued, and other than as set forth in Note 22, did not identify any subsequent events requiring disclosure pursuant to the provisions of FASB ASC Topic 855.
Impact of Adoption of Recent Accounting Standards and New Accounting Standards	Impact of Adoption of Recent Accounting Standards The Company adopted FASB ASU 2014-09 “Revenue from Contracts with Customers (Topic 606)” (“ASU 2014-09”) on January 1, 2018. The objective of ASU 2014-09 is to align the recognition of revenue with the transfer of promised goods or services provided to customers in an amount that reflects consideration which the entity expects to be entitled in exchange for those goods or services. The guidance in this update supersedes the revenue recognition requirements in ASC Topic 605 “Revenue Recognition” , and most industry-specific guidance throughout the industry topics of Codification. Based on management’s evaluation of ASU 2014-09, substantially all of the Company’s interest income and non-interest income were not impacted by the adoption of ASU 2014-09 because the revenue from those contracts with customers is covered by other guidance in U.S. GAAP or the revenue recognition outcomes are similar to the Company’s current revenue recognition practices. The Company evaluated certain noninterest revenue streams, including, deposit related fees, service and interchange fees, merchant income and gains (losses) on the sale of owned real estate (“OREO”) to determine the potential impact of the guidance on the Company’s consolidated financial statements. The Company concluded that a prior period adjustment was not needed upon adoption of ASU 2014-09 using the modified retrospective method. Since the guidance does not apply to revenue associated with financial instruments, the adoption of ASU 2014-09 did not have a material effect on the Company’s consolidated financial statements. The additional disclosures required by ASU 2014-09 have been included in Note 21. The Company adopted FASB ASU 2016-01 “Financial Instruments – Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities” (“ASU 2016-01”) on January 1, 2018. The update enhances the reporting model for financial instruments to provide users of financial statements with more decision-useful information by updating certain aspects of recognition, measurement, presentation and disclosure of financial instruments. Among other changes, the update requires public business entities to: a) use the exit price notion when measuring the fair value of financial instruments for disclosure purposes; b) requires equity investments (except those accounted for under the equity method of accounting or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income; and c) clarifies that entities should evaluate the need for a valuation allowance on a deferred tax asset related to available for sale securities in combination with the entities’ other deferred tax assets. The requirement to use the exit price method for the fair value measurement of financial instruments did not have an impact on the Company’s consolidated financial statements upon adoption of ASU 2016-01, as the Company had elected to use this method in prior reporting periods. The requirement to record changes in the fair value of equity securities in net income did not have a material impact on the Company’s consolidated financial statements upon adoption of ASU 2016-01. The adoption of ASU 2016-01 did not have any impact on the valuation allowance of deferred tax assets related to available for sale securities. The Company adopted FASB ASU 2018-02, “Income Statement – Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income” (ASU 2018-02) on January 1, 2018. ASU 2018-02 was issued to address the income tax accounting treatment of the stranded tax effects within other comprehensive income. This issue came about from the enactment of the Tax Act on December 22, 2017 that changed the Company’s tax rate from 34% to 21%. ASU 2018-02 allowed an entity to elect a reclassification from accumulated other comprehensive income (“AOCI”) to retained earnings for stranded tax effects resulting from the Tax Act. The amount of that reclassification includes the effect of tax rate changes on the deferred tax amount, any related valuation allowance and other income tax effects on the items in AOCI. Upon adoption of ASU 2018-02, the Company reclassified the income tax effect of the Tax Act from AOCI to retained earnings. The reclassification increased AOCI and decreased retained earnings by $156,000 , with zero net effect on total stockholders’ equity. The Company uses the individual security approach for all available for sale securities when releasing income tax effects remaining in AOCI. New Accounting Standards The following are new accounting standards that have been previously disclosed but not yet adopted and includes additional information on the impact the adoption of the standard will have on the Company’s consolidated financial statements: In February 2016, the FASB issued ASU 2016-02 “Leases (Topic 842)” (“ASU 2016-02”). The guidance in the update supersedes the requirements in ASC Topic 840, Leases. The guidance is intended to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet for leases with lease terms of more than 12 months. For public companies, this update will be effective for interim and annual periods beginning after December 15, 2018, and can be applied on a modified retrospective or a transition approach basis. The Company expects to use the transition approach basis, which will allow us to apply ASU 2016-02 at the adoption date, as opposed to applying ASU 2016-02 at the beginning of the earliest period presented. The Company currently has two operating leases that will result in recognition of lease assets and lease liabilities on the consolidated statements of financial condition. The amount of assets and liabilities added to the consolidated statements of financial condition are not expected to have a material impact on the Company’s consolidated financial statements per preliminary estimates. In June 2016, the FASB issued ASU 2016-13, “Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments” (ASU 2016-13). ASU 2016-13 requires credit losses on most financial assets measured at amortized cost and certain other instruments to be measured using an expected credit loss model (referred to as the current expected credit loss (“CECL”) model). Under the CECL model entities will estimate credit losses over the entire contractual term of the instrument (considering estimated prepayments, but not expected extensions or modifications unless reasonable expectation of a troubled debt restructuring exists) from the date of initial recognition of that instrument. Further, ASU 2016-13 made certain targeted amendments to the existing impairment standards for available for sale (“AFS”) debt securities. For an AFS debt security for which there is neither the intent nor a more-likely-than-not requirement to sell, an entity will record credit losses as an allowance rather than a write-down of the amortized cost basis. ASU 2016-13 is effective for public companies that are U.S. Securities and Exchange Commission (“SEC”) filers for fiscal periods beginning after December 15, 2019, including interim reporting periods within those periods. An entity will apply the amendments in ASU 2016-13 through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective. The Company is developing its approach for determining the expected credit losses under the new guidance. Alternative methodologies are being considered, data requirements and integrity are being reviewed and enhancements to the current process are being considered. We expect that the new guidance will result in an increase to the allowance for loan losses given that the allowance will be required to cover the full remaining expected life of the portfolio, rather than the incurred loss under the current accounting standard. The extent of this increase is still being evaluated. We are also reviewing the impact of additional disclosures required under ASU 2016-13 on our ongoing financial reporting procedures .
Reclassifications	Reclassifications Certain amounts in the 2017 and 2016 consolidated financial statements have been reclassified to conform with the 2018 presentation format. These reclassifications had no effect on net income.

Allowance for Loan Losses (Poli

Allowance for Loan Losses [Abstract]
Impaired Financing Receivable	A loan is considered impaired when, based on current information and events, it is probable that the Company will not be able to collect the scheduled payments of principal and interest when due according to the contractual terms of the loan agreement. Factors considered in determining impairment include payment status, collateral value and the probability of collecting scheduled payments when due. Impairment is measured on a loan-by-loan basis for commercial real estate loans and commercial loans. Larger groups of smaller balance homogeneous loans are collectively evaluated for impairment. Accordingly, the Company does not separately identify individual consumer, home equity, or one- to four-family loans for impairment disclosure, unless they are subject to a troubled debt restructuring.
Nonaccrual Loan Status	The accrual of interest on loans is discontinued when, in management’s opinion, the borrower may be unable to meet payments as they become due. A loan does not have to be 90 days delinquent in order to be classified as non-accrual. When interest accrual is discontinued, all unpaid accrued interest is reversed. If ultimate collection of principal is in doubt, all cash receipts on impaired loans are applied to reduce the principal balance.
Financing Receivable Credit Quality	The Company’s policies provide for the classification of loans as follows: · Pass/Performing; · Special Mention – does not currently expose the Company to a sufficient degree of risk but does possess credit deficiencies or potential weaknesses deserving the Company’s close attention; · Substandard – has one or more well-defined weaknesses and are characterized by the distinct possibility that the Company will sustain some loss if the deficiencies are not corrected. A substandard asset would be one inadequately protected by the current net worth and paying capacity of the obligor or pledged collateral, if applicable; · Doubtful – has all the weaknesses inherent in substandard loans with the additional characteristic that the weaknesses present make collection or liquidation in full on the basis of currently existing facts, conditions and values questionable, and there is a high possibility of loss; and · Loss – loan is considered uncollectible and continuance without the establishment of a specific valuation reserve is not warranted.  The Company’s Asset Classification Committee is responsible for monitoring risk ratings and making changes as deemed appropriate. Each commercial loan is individually assigned a loan classification. The Company’s consumer loans, including residential one- to four-family loans and home equity loans, are not classified as described above. Instead, the Company uses the delinquency status as the basis for classifying these loans. Generally, all consumer loans more than 90 days past due are classified and placed in non-accrual. Such loans that are well-secured and in the process of collection will remain in accrual status.
Loans and Leases Receivable, Troubled Debt Restructuring	Troubled debt restructurings (“TDRs”) occur when we grant borrowers concessions that we would not otherwise grant but for economic or legal reasons pertaining to the borrower’s financial difficulties. A concession is made when the terms of the loan modification are more favorable than the terms the borrower would have received in the current market under similar financial difficulties. These concessions may include, but are not limited to, modifications of the terms of the debt, the transfer of assets or the issuance of an equity interest by the borrower to satisfy all or part of the debt, or the addition of borrower(s). The Company identifies loans for potential TDRs primarily through direct communication with the borrower and evaluation of the borrower’s financial statements, revenue projections, tax returns, and credit reports. Even if the borrower is not presently in default, management will consider the likelihood that cash flow shortages, adverse economic conditions, and negative trends may result in a payment default in the near future. Generally, we will not return a TDR to accrual status until the borrower has demonstrated the ability to make principal and interest payments under the restructured terms for at least six consecutive months. The Company’s TDRs are impaired loans, which may result in specific allocations and subsequent charge-offs if appropriate.  Some loan modifications classified as TDRs may not ultimately result in full collection of principal and interest, as modified, which may result in potential losses. These potential losses have been factored into our overall estimate of the allowance for loan losses.
Foreclosed Real Estate	Foreclosed Real Estate Foreclosed real estate consists of property acquired in settlement of loans which is carried at its fair value less estimated selling costs. Write-downs from cost to fair value less estimated selling costs are recorded at the date of acquisition or repossession and are charged to the allowance for loan losses. Subsequent write-downs to fair value, net of estimated selling costs, are recorded in non-interest expense along with direct operating expenses. Gains or losses not previously recognized, resulting from the sale of foreclosed assets are recognized in non-interest expense on the date of sale. Foreclosed real estate was $678,000 and $435,000 at December 31, 2018 and 2017, respectively, and was included as a component of other assets in the consolidated statement of financial condition. Proceeds from the sale of foreclosed real estate for the years ended December 31, 2018, 2017 and 2016 were $1.5 million , $331,000 , and $619,000 , respectively. This resulted in a net gain on sale of $44,000 , $8,000 and $9,000 for the years ended December 31, 2018, 2017 and 2016, respectively, and was included as a component of other non-interest expenses in the consolidated statement of income.

Fair Value of Financial Instruments [Abstract]
Fair Value of Financial Instruments	The measurement of fair value under FASB ASC Topic 820, “Fair Value Measurements and Disclosures” (“ASC Topic 820”) establishes a fair value hierarchy that prioritizes the inputs to valuation methods used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities measurements (Level 1) and the lowest priority to unobservable input measurements (Level 3). The three levels of the fair value hierarchy under ASC Topic 820 are as follows: Level 1: Unadjusted quoted prices in active markets for identical assets or liabilities that the reporting entity can access at the measurement date.  Level 2: Inputs other than quoted prices included in Level 1 that are observable for the asset or liability either directly or indirectly.  Level 3: Unobservable inputs for determining the fair values of assets or liabilities that reflect an entity’s own assumptions about the assumptions that market participants would use in pricing the assets or liabilities.  An asset’s or liability’s level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement.
Fair Value Transfer	Any transfers between levels would be recognized as of the actual date of event or change in circumstances that caused the transfer.

Revenue Recognition [Abstract]
Revenue Recognition	As of January 1, 2018, the Company adopted FASB ASU 2014-09 “Revenue from Contracts with Customers (Topic 606)” (“ASU 2014-09”) for non-interest revenue streams. The Company has elected to apply ASU 2014-09 using the modified retrospective method. The implementation of the new standard did not have a material impact on the measurement or recognition of revenue; and as such, a cumulative effect adjustment to retained earnings was not deemed necessary under the modified retrospective implementation method. The adoption of ASU 2014-09 did, however, require additional disclosures.  The Company’s non-interest revenue streams primarily result from services it provides to its deposit customers. When a customer makes a deposit, the Company records a liability under ASC 405 “Liabilities” because the Company has an obligation to deliver cash to its customer on demand. A contract between the Company and a deposit account customer is typically documented in writing and is often terminable at will by the customer alone or by both the customer and the Company without penalty. The term of a deposit contract between a customer and the Company will likely be day-to-day or minute-to-minute, and the termination clause is likely similar to a renewal right where each day or minute represents the renewal of the contract. The Company generally fully satisfies its performance obligations on its contracts with customers as services are rendered and the transaction prices are typically fixed; charged either on a periodic basis or based on activity. Because performance obligations are satisfied as services are rendered and the transaction prices are fixed, there is little judgment involved in applying Topic 606 that significantly affects the determination of the amount and timing of revenue from contracts with customers. The Company’s primary non-interest revenue streams within the scope of ASU 2014-09 are described in further detail below. The Company has no material unsatisfied performance obligations as of December 31, 2018.  Service Charges on Deposit Accounts Service charges and fees on deposit accounts consist of transaction-based fees, account maintenance fees, and overdraft service fees for various retail and business deposit customers. Transaction-based fees, such as stop payment charges, are recognized at the time the Company fulfills the customer’s request. Account maintenance fees, which relate primarily to monthly maintenance, are earned over the course of a month, representing the period over which the Company satisfies the performance obligation. Overdraft fees are recognized at the point in time that the overdraft occurs. Service charges on deposits are withdrawn directly from the customer’s account balance.  Fees, Interchange Income, and Other Service Charges Fees, interchange income, and other service charges are primarily comprised of debit card income, ATM fees, merchant services income and other service charges. Debit card income is primarily comprised of interchange fees earned whenever the Company’s debit cards are used to purchase goods or services from a merchant via a card payment network, such as MasterCard. Interchange fees from cardholder transactions represent a percentage of the underlying transaction value. ATM fees are comprised of fees earned whenever a Company’s ATM or debit card is used at a non-Company ATM or a non-Company cardholder uses a Company ATM. ATM fees represent a fixed fee for the convenience to cardholders for accessibility of funds. Merchant services income mainly represents fees charged to merchants serviced by a third party vendor under contract with the Company for debit or credit card processing, and represents a percentage of the underlying transaction value. Other service charges include revenue from services provided to our retail or business customers, which may include fees for wire transfer processing, bill pay services, cashier’s checks and other services. The Company’s performance obligation for fees, interchange income and other service charges are largely satisfied, and related revenue recognized, when the services are rendered or upon completion. Payment is typically immediately or in the following month.  Other Other non-interest income consists of safe deposit rental fees. Safe deposit box rental fees are charged to the customer on an annual basis and recognized upon receipt of payment. The Company determined that since rentals and renewals occur fairly consistently over time, revenue is recognized on a basis consistent with the duration of the performance obligation.  Gain/Losses on Sale of OREO The Company records a gain or loss from the sale of other real estate owned (“OREO”) when control of the property transfers to the buyer, which generally occurs at the time of an executed deed. When the Company finances the sale of OREO to the buyer, the Company assesses whether the buyer is committed to perform their obligations under the contract and whether collectability of the transaction price is probable. Once these criteria are met, the OREO asset is derecognized and the gain or loss on sale is recorded upon the transfer of control of the property to the buyer. In determining the gain or loss on the sale, the Company adjusts the transaction price and related gain (loss) on sale if a significant financing component is present. Gains (losses) on the sale of OREO are generally recorded in non-interest expense on the consolidated statement of income as an offset to OREO expenses. During the year ended December 31, 2018, the Company financed the sale of an OREO property to a buyer. After assessing the applicable criteria under ASU 2014-09, the Company recognized a $33,000 gain on sale of the property. There were no sales of OREO during the year ended December 31, 2017 where the Company financed the sale of the property. Contract Balances The Company’s non-interest revenue streams are largely based on transactional activity. Consideration is often received immediately or shortly after the Company satisfies its performance obligation and revenue is recognized. The Company does not typically enter into long-term revenue contracts with customers, and therefore, does not experience significant contract balances. As of December 31, 2018 and 2017, the Company did not have any significant contract balances.

Although the plans are unfunded, the Company has purchased bank owned life insurance for the purpose of funding the liability. The cash surrender value of bank owned life insurance amounted to $7.4 million and $7.3 million at December 31, 2018 and 2017, respectively. Annual benefits increase at a predetermined amount until the executive or director reaches a predetermined retirement age.

Benefit plan amendment description					Effective January 27, 2016, the Company amended the 2001 Supplemental Benefit Plan for Directors, resulting in a change to the benefit formula from a fixed, pre-determined dollar benefit. The formula provides a benefit equal to a percentage of the director's average pay. The average pay is multiplied by number of years of service, not to exceed 20 years of service or 40% of average final pay. The benefit is payable over a period of fifteen years beginning the month following age 72, unless termination occurs due to disability, death or a change in control. Effective May 18, 2016, the Company amended the 2001 Supplemental Benefit Plan for Executives resulting in a change in the benefit formula from a fixed, pre-determined dollar benefit to a formula-based benefit. The formula provides a benefit equal to a percentage of the executive's average pay. The average pay is multiplied by number of years of service, not to exceed 20 years of service or 40% of average final pay. A reduced benefit is payable if a termination of service occurs prior to age 65. The benefit is payable over a period of fifteen years beginning the month following age 65, unless termination occurs due to disability, death or a change in control.

The 2012 Plan was amended on May 18, 2016 to update the fixed, pre-determined annual benefit amount. The 2012 Plan provides for a reduced benefit in the event the Executive terminates his employment for a reason other than death, disability, cause or a change in control, before the Executive attains the age 67, which will be paid in monthly installments for 15 years. In the event of death, the vested benefit is payable to the beneficiary as a lump sum payment.

Defined benefit plan description					Effective May 18, 2016, the Company amended the 2001 Supplemental Benefit Plan for Executives resulting in a change in the benefit formula from a fixed, pre-determined dollar benefit to a formula-based benefit. The formula provides a benefit equal to a percentage of the executive's average pay. The average pay is multiplied by number of years of service, not to exceed 20 years of service or 40% of average final pay. A reduced benefit is payable if a termination of service occurs prior to age 65. The benefit is payable over a period of fifteen years beginning the month following age 65, unless termination occurs due to disability, death or a change in control.

Defined benefit plan description					Effective March 29, 2018, the Company entered into a Retention Agreement with one executive. The agreement provides that the Executive will receive a payment of $1.4 million (the "Normal Retention Payment") provided that the Executive remains continuously employed with the Bank through March 29, 2028 (the "Retention Date"). The Normal Retention Payment will be paid in three equal installments on March 29, 2028, January 2, 2029, and January 2, 2030. If the Executive's employment is terminated without cause or for good reason (as defined in the agreement) prior to the Retention Date, the Executive will receive the vested account balance as set forth in the agreement. In the event that the Executive's employment terminates prior to the Retention Date due to death or disability, the Executive or his beneficiary, as applicable, will generally receive the vested account balance. If the Executive's employment is terminated prior to the Retention Date, and within two years of a change in control (as defined in the agreement), the Executive will receive the Normal Retention Payment in a lump sum payment.

Fair value measurements, valuation techniques	Periodically, the Company records non-recurring adjustments to the carrying value of loans based on fair value measurements for partial charge-offs of the uncollectible portions of these loans. Non-recurring adjustments also include certain impairment amounts for collateral-dependent loans calculated as required by ASC Topic 310, "Receivables – Loan Impairment," when establishing the allowance for loan losses. An impaired loan is carried at fair value based on either a recent appraisal less estimated selling costs of underlying collateral or discounted cash flows based on current market conditions.

Asset-backed securities – private label transferred from Level 3 category to Level 2 category, description	During the year ended December 31, 2018, asset-backed securities – private label were transferred from the Level 3 category to the Level 2 category. These securities were transferred to Level 2 because the Company changed its method of valuing these securities and that method now uses Level 2 inputs. These securities are now valued using Level 2 inputs because the price volatility associated with these securities has been reduced and management considers the quoted market price for these securities to be reasonable.
Fair Value Inputs Level 1 And Level 2 [Member] | Available-for-sale Securities [Member] | Fair Value, Measurements, Recurring [Member]
Fair Value, Assets and Liabilities Measured on Recurring and Nonrecurring Basis [Line Items]
Fair value measurements, valuation techniques	The fair value of securities available for sale are determined by obtaining quoted market prices on nationally recognized securities exchanges (Level 1) or matrix pricing (Level 2), which is a mathematical technique used widely in the industry to value debt securities without relying exclusively on quoted market prices for the specific securities, but rather by relying on the securities' relationship to other benchmark quoted prices. The fair value measurements consider observable data that may include dealer quotes, market spreads, cash flows, the U.S. treasury yield curve, live trading levels, trade execution date, market consensus prepayment speeds, credit information, and the security' terms and conditions, among other things. Level 2 securities which are fixed income instruments that are not quoted on an exchange, but are traded in active markets, are valued using prices obtained from our custodian, who use third party data service providers.
Reclassifications between the Level 1 and Level 2, description	Any transfers between levels would be recognized as of the actual date of event or change in circumstances that caused the transfer. There were no reclassifications between the Level 1 and Level 2 categories for the years ended December 31, 2018 and 2017.

Fair Value, Assets and Liabilities Measured on Recurring and Nonrecurring Basis [Line Items]
Fair value measurements, valuation techniques	Level 2 inputs for assets or liabilities measured at fair value on a recurring basis might include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability (such as interest rates, volatilities, prepayment speeds, credit risks, etc.) or inputs that are derived principally from or corroborated by market data by correlation or other means.
Significant Other Unobservable Inputs (Level 3) [Member]
Fair Value, Assets and Liabilities Measured on Recurring and Nonrecurring Basis [Line Items]
Fair value measurements, valuation techniques	At December 31, 2017, Level 3 inputs were determined by the Company's management using inputs from its third party financial advisor on a quarterly basis. The significant unobservable inputs used in the fair value measurement of the reporting entity's asset-backed, private label securities are prepayment rates, probability of default and loss severity in the event of default. Significant increases or decreases in any of those inputs in isolation would result in a significantly lower or higher fair value measurement. Generally, a change in the assumption used for the probability of default is accompanied by a directionally similar change in the assumption used for the loss severity and a directionally opposite change in the assumption used for prepayment rates.

As a result, any unrealized gains and losses for assets within the Level 3 category may include changes in fair value attributable to both observable (e.g., changes in market interest rates) and unobservable (e.g., changes in unobservable long-dated volatilities) inputs.
