Basis Of Presentation [Abstract]
Basis Of Presentation	1 - BASIS OF PRESENTATION The accounting and reporting policies of The First of Long Island Corporation (“Corporation”) reflect banking industry practice and conform to generally accepted accounting principles (“GAAP”) in the United States. In preparing the consolidated financial statements, management is required to make estimates, such as the allowance for loan losses, and assumptions that affect the reported asset and liability balances, revenue and expense amounts, and the disclosure of contingent assets and liabilities. Actual results could differ significantly from those estimates. The consolidated financial statements include the accounts of the Corporation and its wholly-owned subsidiary, The First National Bank of Long Island (“Bank”). The Bank has two wholly owned subsidiaries: FNY Service Corp. and The First of Long Island Agency, Inc. The Bank and FNY Service Corp. jointly own another subsidiary, The First of Long Island REIT, Inc., a real estate investment trust. The consolidated entity is referred to as the “Corporation” and the Bank and its subsidiaries are collectively referred to as the “Bank.” All intercompany balances and amounts have been eliminated. For further information refer to the consolidated financial statements and notes thereto included in the Corporation's Annual Report on Form 10-K for the year ended December 31, 201 8 . The consolidated financial information included herein as of and for the periods ended September 30, 2019 and 2018 is unaudited. However, such information reflects all adjustments which are, in the opinion of management, necessary for a fair statement of results for the interim periods. The December 31, 201 8 consolidated balance sheet was derived from the Corporation's December 31, 201 8 audited consolidated financial statements. When appropriate, items in the prior year financial statements are reclassified to conform to the current period presentation.

For purposes of computing EPS, these RSUs were considered to participate with common stock in the earnings of the Corporation and, therefore, the Corporation calculated basic and diluted EPS using the two-class method. Substantially all of the RSUs awarded in 2016 vested on December 31, 2018. As a result, beginning in 2019, the Corporation calculates basic and dilutive EPS using the trea sury stock method.

Comprehensive Income	3 - COMPREHENSIVE INCOME Comprehensive income includes net income and other comprehensive income (loss). Other comprehensive income (loss) includes revenues, expenses, gains and losses that under GAAP are included in comprehensive income but excluded from net income. Other comprehensive income (loss) for the Corporation consists of unrealized holding gains or losses on available-for-sale securities and derivative instruments and changes in the funded status of the Bank’s defined benefit pension plan, all net of related income taxes. Accumulated other comprehensive income (loss) is recognized as a separate component of stockholders’ equity. The components of other comprehensive income (loss) and the related tax effects are as follows: Nine Months Ended Three Months Ended September 30, September 30, (in thousands) 2019 2018 2019 2018 Change in net unrealized holding gains (losses) on available-for-sale securities: Change arising during the period $ 16,479 $ ( 22,059 ) $ 848 $ ( 7,231 ) Reclassification adjustment for net loss included in net income (1) — 4,960 — 4,960 16,479 ( 17,099 ) 848 ( 2,271 ) Tax effect 4,941 ( 5,166 ) 254 ( 686 ) 11,538 ( 11,933 ) 594 ( 1,585 ) Change in funded status of pension plan: Amortization of net actuarial loss included in net income (2) 264 — 88 — Tax effect 118 — 26 — 146 — 62 — Change in net unrealized gains (loss) on derivative instruments: Change arising during the period ( 4,757 ) ( 34 ) ( 516 ) 462 Reclassification adjustment for net interest expense included in net income (3) 423 315 240 225 ( 4,334 ) 281 ( 276 ) 687 Tax effect ( 1,295 ) 85 ( 83 ) 207 ( 3,039 ) 196 ( 193 ) 480 Other comprehensive income (loss) $ 8,645 $ ( 11,737 ) $ 463 $ ( 1,105 ) (1) Represents net realized loss arising from the sale of available-for-sale securities.

Troubled Debt Restructurings. A restructuring constitutes a troubled debt restructuring when it includes a concession by the Bank and the borrower is experiencing financial difficulty. In order to determine whether a borrower is experiencing financial difficulty, an evaluation is performed of the probability that the borrower will be in payment default on any of its debt in the foreseeable future without the modification. The Bank performs the evaluation under its internal underwriting policy. The Bank did no t modify any loans in troubled debt restructurings during the first nine months of 2019. During the nine months ended September 30, 2018, the Bank modified two consumer loans to a single borrower into one loan in a troubled debt restructuring amounting to $ 350,000 . The term of the restructured loan was extended for 12 months and the post-modification interest rate was lower than the current market rate for new debt with similar risk . At September 30, 2019 and December 31, 2018, the Bank had an allowance for loan losses of $ 15,000 and $ 16,000 , respectively, allocated to specific troubled debt restructurings. The Bank had no commitments to lend additional amounts in connection with loans that were classified as troubled debt restructurings. There were no troubled debt restructurings for which there was a payment default during the nine months ended September 30, 2019 and 2018 that were modified during the 12-month period prior to default. A loan is considered to be in payment default once it is 90 days contractually past due under the modified terms. Risk Characteristics . Credit risk within the Bank’s loan portfolio primarily stems from factors such as changes in the borrower’s financial condition, credit concentrations, changes in collateral values, economic conditions and environmental contamination of properties securing mortgage loans. The Bank’s commercial loans, including those secured by real estate mortgages, are primarily made to small and medium-sized businesses. Such loans sometimes involve a higher degree of risk than those to larger companies because such businesses may have shorter operating histories, higher debt-to-equity ratios and may lack sophistication in internal record keeping and financial and operational controls. In addition, most of the Bank’s loans are made to businesses and consumers on Long Island and in the boroughs of New York City (“NYC”), and a large percentage of these loans are mortgage loans secured by properties located in those areas. The primary sources of repayment for residential and commercial mortgage loans include employment and other income of the borrowers, the businesses of the borrowers and cash flows from the underlying properties. In the case of multifamily mortgage loans, a substantial portion of the underlying properties are rent stabilized or rent controlled. These sources of repayment are dependent on, among other things, the strength of the local economy. Credit Quality Indicators. The Corporation categorizes loans into risk categories based on relevant information about the borrower’s ability to service their debt including, but not limited to, current financial information for the borrower and any guarantors, payment experience, credit underwriting documentation, public records, due diligence checks and current economic trends. Commercial and industrial loans and commercial mortgage loans are risk rated utilizing a ten point rating system. The ten point risk rating system is described hereinafter. Internally Assigned Risk Rating 1 – 2 Cash flow is of high quality and stable. Borrower has very good liquidity and ready access to traditional sources of credit. This category also includes loans to borrowers secured by cash and/or marketable securities within approved margin requirements. 3 – 4 Cash flow quality is strong, but shows some variability. Borrower has good liquidity and asset quality. Borrower has access to traditional sources of credit with minimal restrictions. 5 – 6 Cash flow quality is acceptable but shows some variability. Liquidity varies with operating cycle and assets provide an adequate margin of protection. Borrower has access to traditional sources of credit, but generally on a secured basis. 7 Watch - Cash flow has a high degree of variability and subject to economic downturns. Liquidity is strained and the ability of the borrower to access traditional sources of credit is diminished. 8 Special Mention - The borrower has potential weaknesses that deserve management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loan or in the Bank’s credit position at some future date. Special mention assets are not adversely classified and do not expose the Bank to risk sufficient to warrant adverse classification. 9 Substandard - Loans are inadequately protected by the current sound worth and paying capacity of the borrower or the collateral pledged, if any. Loans so classified have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the Bank will sustain some loss if the deficiencies are not corrected. 10 Doubtful - Loans have all the inherent weaknesses of those classified substandard with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions and values, highly questionable and improbable. Risk ratings on commercial and industrial loans and commercial mortgages are initially assigned during the underwriting process and affirmed as part of the approval process. The ratings are periodically reviewed and evaluated based on borrower contact, credit department review or independent loan review. The Bank's loan risk rating and review policy establishes requirements for the annual review of commercial real estate and commercial and industrial loans. The requirements include details of the scope of coverage and selection process based on loan-type and risk rating. Among other things, at least 80 % of the recorded investment of commercial real estate loans as of December 31 of the prior year must be reviewed annually. Lines of credit are also reviewed annually at each proposed reaffirmation. The frequency of the review of other loans is determined by the Bank’s ongoing assessments of the borrower’s condition. Residential mortgage loans, revolving home equity lines and other consumer loans are risk rated utilizing a three point rating system. In most cases, the borrower’s credit score dictates the risk rating. However, regardless of credit score, loans that are on management’s watch list or have been criticized or classified by management are assigned a risk rating of 3. A credit score is a tool used in the Bank’s loan approval process, and a minimum score of 680 is generally required for new loans. Credit scores for each borrower are updated at least annually. The risk ratings along with their definitions are as follows: Internally Assigned Risk Rating 1 Credit score is equal to or greater than 680. 2 Credit score is 635 to 679. 3 Credit score is below 635 or, regardless of credit score, the loan has been classified, criticized or placed on watch by management. The following tables present the recorded investment in commercial and industrial loans and commercial mortgage loans by class of loans and risk rating. Loans shown as Pass are all loans other than those risk rated Watch, Special Mention, Substandard or Doubtful.

Fair Value Of Financial Instruments [Abstract]
Fair Value Of Financial Instruments	8 - FAIR VALUE OF FINANCIAL INSTRUMENTS Financial Instruments Recorded at Fair Value . When measuring fair value, the Corporation uses a fair value hierarchy, which is designed to maximize the use of observable inputs and minimize the use of unobservable inputs. The hierarchy involves three levels of inputs that may be used to measure fair value: Level 1: Quoted prices (unadjusted) in active markets for identical assets or liabilities that the Corporation has the ability to access at the measurement date. Level 2: Significant other observable inputs other than Level 1 prices such as 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; or inputs other than quoted prices that are observable or can be corroborated by observable market data. Level 3: Significant unobservable inputs that reflect the Corporation’s own assumptions about the assumptions that market participants would use in pricing an asset or liability. The Corporation deems transfers between levels of the fair value hierarchy to have occurred on the date of the event or change in circumstance that caused the transfer. There were no transfers between levels of the fair value hierarchy during the nine months ended September 30, 2019 or 2018. The fair values of the Corporation’s financial assets and liabilities measured at fair value on a recurring basis are set forth in the table that follows. The fair values of available-for-sale securities are determined on a recurring basis using matrix pricing (Level 2 inputs). Matrix pricing, which is a mathematical technique widely used in the industry to value debt securities, does not rely exclusively on quoted prices for the specific securities but rather on the relationship of such securities to other benchmark quoted securities. Where no significant other observable inputs were available, Level 3 inputs were used. The fair values of interest rate swaps are based on valuation models using observable market data as of the measurement date resulting in a Level 2 classification.

Financial Instruments Not Recorded at Fair Value. Fair value estimates are made at a specific point in time. Such estimates are generally subjective in nature and dependent upon a number of significant assumptions associated with each financial instrument or group of similar financial instruments, including estimates of discount rates, liquidity, risks associated with specific financial instruments, estimates of future cash flows, and relevant available market information. Changes in assumptions could significantly affect the estimates. In addition, fair value estimates do not reflect the value of anticipated future business, premiums or discounts that could result from offering for sale at one time the Corporation’s entire holdings of a particular financial instrument, or the income tax consequences of realizing gains or losses on the sale of financial instruments. The following table sets forth the carrying amounts and estimated fair values of financial instruments that are not recorded at fair value in the Corporation’s financial statements.

Leases [Abstract]
Leases	9 – LEASES As described in “Note 12 – Adoption of New Accounting Standards,” the Bank adopted Accounting Standards Update (“ASU”) 2016-02 “Leases” and all subsequent amendments on January 1, 2019. The Bank leases certain branch and back-office locations under long-term, non-cancelable operating lease agreements. The leases expire at various dates through 2032 and have a weighted average remaining term of 7. 61 years at September 30, 2019. Many of the Bank’s leases include renewal options of up to 10 years. The exercise of lease renewal options is at the Bank’s sole discretion. Rental payments required by the Bank’s lease agreements may increase over time based on certain variable components such as real estate taxes and common area maintenance charges. The Bank determines if an arrangement is a lease at inception. ASU 2016-02 requires the recognition of a right-of-use (“ROU”) asset and lease liability at the commencement date based on the present value of lease payments over the lease term. As most of the Bank’s leases do not provide an implicit interest rate, the Bank uses its incremental borrowing rate to determine the present value of the lease payments. The weighted average discount rate for leases in place at September 30, 2019 was 3.09 % . For leases entered into on a going forward basis, the Bank’s ROU asset and lease liability may include options to extend the lease when it is reasonably certain that the Bank will exercise that option. Lease expense will be recognized on a straight-line basis over the lease term. Leases with an initial term of 12 months or less are not recorded on the balance sheet. The Bank has one such lease at September 30, 2019 and recognizes lease expense for this lease on a straight-line basis over the lease term. The components of lease expense for the nine and three months ended September 30, 2019 are as follows: Nine Month Ended Three Months Ended (in thousands) September 30, 2019 September 30, 2019 Operating lease cost $ 1,969 $ 662 Variable lease cost 345 104 Short-term lease cost 3 — $ 2,317 $ 766 The following is a maturity analysis of the operating lease liability as of September 30, 2019.

Revenue From Contracts With Customers [Abstract]
Revenue From Contracts With Customers	10 – REVENUE FROM CONTRACTS WITH CUSTOMERS The noninterest income section of the consolidated statements of income includes the following types of revenues earned from the Bank's contracts with customers. Investment Management Division (“IMD”) Revenues. The Bank holds customer assets in a fiduciary capacity and provides various services, including trust account services, estate settlement, custody and asset management. The services are performed for customers over time, requiring a time-based measure of progress. Fees are assessed based on market values of customer assets held or under management as of a certain point in time, and income cannot be estimated prior to the end of the measurement period. Volatility in equity and other market values will impact the amount of revenue that will be earned. Fees are generally earned and collected on a monthly or quarterly basis, accrued to income as earned and included in the consolidated statements of income in the line item "Investment Management Division income." Deposit Account Revenues. Fees are earned and collected on a monthly basis for account maintenance and activity-based service charges on deposit accounts. The services are performed for customers over time, requiring a time-based measure of progress. Customers may be required to maintain minimum balances and average balances. Additional fees may also be earned for overdrafts, replacement of debit cards, bill payment, lockbox services and ACH services, among others, and are earned and collected as transactions take place. All deposit account fees are accrued to income as earned, either monthly or at the point of sale, and included in the consolidated statements of income in the line item "Service charges on deposit accounts." Transaction and Branch Service Fees. The following revenue streams are components of “Other noninterest income” on the consolidated statements of income. These components totaled $ 1,717,000 and $ 1,567,000 for the nine months ended September 30, 2019 and 2018, respectively. Other items included in “Other noninterest income,” such as bank-owned life insurance (“BOLI”) income, non-service components of net pension cost and real estate tax refunds are excluded from revenue from contracts with customers. Debit/Credit Card Revenues . The Bank earns a fee when its customers use their debit or credit cards in point-of-sale transactions. These fees are generally known as interchange fees. Interchange fees from cardholder transactions represent a percentage of the underlying transaction value and are recorded daily, concurrently with the transaction processing services provided to the cardholder. Branch Services Revenues. The Bank charges fees for safe deposit box rentals, wire transfers, money orders, checkbook printing, official checks and ATM usage. Fees are earned, collected and generally recorded as revenue when the service is provided. Investment Advisory Services. The Bank provides branch space to a third party who sells financial products to the Bank’s customers and pays commissions to the Bank based on the products sold. Commissions are variable and based on the market values of financial assets sold. Commissions are accrued to income as earned.

Derivatives [Abstract]
Derivatives	11 – DERIVATIVES As part of its asset liability management activities, the Corporation utilizes interest rate swaps to help manage its interest rate risk position. The notional amount of an interest rate swap does not represent the amount exchanged by the parties. The exchange of cash flows is determined by reference to the notional amount and the other terms of the interest rate swap agreements. The Bank entered into an interest rate swap with a notional amount totaling $ 150 million on May 22, 2018 and a second interest rate swap with a notional amount of $ 50 million on January 17, 2019. The interest rate swaps were designated as cash flow hedges of certain Federal Home Loan Bank (“FHLB”) advances and brokered certificates of deposit (“CDs”). The swaps were determined to be fully effective during the periods presented and therefore no amount of ineffectiveness has been included in net income. The aggregate fair value of the swaps is recorded in other liabilities, with changes in fair value net of related income taxes recorded in other comprehensive income (loss). The amount included in accumulated other comprehensive income (loss) would be reclassified to current earnings should the hedges no longer be considered effective. The Corporation expects the hedges to remain fully effective during the remaining term of the swaps. The following table summarizes information about the interest rate swaps designated as cash flow hedges. September 30, 2019 December 31, 2018 Notional amount $ 200 million $ 150 million Weighted average fixed pay rate 2.83 % 2.90 % Weighted average 3-month LIBOR receive rate 2.36 % 2.38 % Weighted average maturity 2.31 Years 2.43 Years Interest expense recorded on the swap transactions, which totaled $ 423,000 for the nine months ended September 30, 2019, is recorded as a component of interest expense in the consolidated statements of income. Amounts reported in accumulated other comprehensive income (loss) related to swaps will be reclassified to interest expense as interest payments are made on the Bank’s variable-rate liabilities. During the nine months ended September 30, 2019, the Corporation had $ 423,000 of reclassifications to interest expense. During the next 12 months, the Corporation estimates that $ 2,114,000 will be reclassified as an increase to interest expense. The following table presents the net (gains) losses recorded in the consolidated statements of income and the consolidated statements of comprehensive income relating to interest rate swaps for the nine and three months ended September 30, 2019 and 2018.

The Bank’s agreement with its interest rate swap counterparty sets forth minimum collateral posting thresholds. If the termination value of the swap is a net asset position, the counterparty may be required to post collateral against its obligations to the Bank under the agreement. However, if the termination value of the swap is a net liability position, the Bank may be required to post collateral to the counterparty. At September 30, 2019, the Bank is in compliance with the collateral posting provisions to its counterparty under the agreement of approximately $ 5.6 million. If the Bank had breached any of these provisions at September 30, 2019, it could have been required to settle its obligations under the agreement at the termination value.

Basis Of Presentation [Abstract]
Adoption of New Accounting Standards	12 – ADOPTION OF NEW ACCOUNTING STANDARDS In February 2016, the Financial Accounting Standards Board (“FASB”) issued ASU 2016-02 “Leases.” ASU 2016-02 affects any entity that enters into a lease and is intended to increase the transparency and comparability of financial statements among organizations. The ASU requires, among other changes, a lessee to recognize on its balance sheet a lease asset and a lease liability for those leases previously classified as operating leases. The lease asset represents the right to use the underlying asset for the lease term and the lease liability represents the discounted value of the required lease payments to the lessor. The ASU also requires entities to disclose key information about leasing arrangements. The Corporation implemented ASU 2016-02 on January 1, 2019 utilizing the transition method described in ASU 2018-11 “Leases – Targeted Improvements.” Upon adoption of the ASU, the Corporation recorded a right-of-use asset and lease liability of $ 15.7 million and $ 16.5 million, respectively, for its outstanding operating leases. Implementation did not significantly impact the Corporation’s results of operations, cash flows or regulatory capital ratios. See “Note 9 – Leases” for disclosures required by ASU 2016-02. The Corporation elected the package of practical expedients permitted in ASU 2016-02. Accordingly, the Bank accounted for its existing operating leases as operating leases under the new guidance, without reassessing (a) whether the contracts contain a lease under ASU 2016-02, (b) whether classification of the operating leases would be different in accordance with ASU 2016-02, or (c) whether the unamortized initial direct costs before transition adjustments (as of December 31, 2018) would have met the definition of initial direct costs in ASU 2016-02 at lease commencement. In July 2019, the FASB issued ASU 2019-07 “Codification Updates to SEC Sections” which discusses amendments pursuant to SEC Final Rule Release No. 33-10532, Disclosure Update and Simplification. The ASU provides, among other changes, updated disclosure rules with regards to the Statements of Changes in Stockholders’ Equity (“SCSE”) and is effective immediately for interim financial statements. The ASU provides two options for presentation of the SCSE. The entity may choose either a reconciliation for the current and comparative year-to-date periods, with subtotals for each interim period, or a reconciliation for the current quarter and year-to-date interim periods as well as the comparative periods of the prior year. The Corporation adopted ASU 2019-07 and its SCSE is presented as a year-to-date reconciliation with subtotals for each interim period for the nine months ended 2019 and 2018.

Impact Of Issued But Not Yet Effective Accounting Standards [Abstract]
Impact Of Issued But Not Yet Effective Accounting Standards	13 – IMPACT OF IS SUED BUT NOT YET EFFECTIVE ACCOUNTING STANDARDS The pronouncements discussed in this section are not intended to be an all-inclusive list, but rather only those pronouncements that could potentially have an impact on the Corporation’s financial position, results of operations or disclosures. In June 2016, the FASB issued ASU 2016-13 “Measurement of Credit Losses on Financial Instruments.” ASU 2016-13 affects entities holding financial assets that are not accounted for at fair value, including loans, debt securities and other financial assets. The ASU requires financial assets measured at amortized cost to be presented at the net amount expected to be collected by recording an allowance for credit losses. ASU 2016-13 is effective for interim and annual reporting periods beginning after December 15, 2019. Management has established an internal committee to manage the implementation of the ASU. The committee is led by the Bank’s Chief Accounting Officer and includes the EVP/CEO Successor, Chief Financial Officer, Chief Risk Officer, Chief Credit Officer, Controller, Manager of Accounting Controls and Chief Auditor. A broader group of Bank staff has been identified to assist in implementing the ASU, including representatives of the Bank’s loan operations, credit administration, lending, investments and technology functions. The committee has engaged a third-party software provider, developed an implementation timeline, and accumulated and reconciled all necessary historical data. An independent firm is currently conducting model validation. Decisions have been made regarding all substantive aspects of the implementation including, among others, loan pools and segmentation, methodologies, historical look-back period, forecasting and qualitative factors. The committee has begun parallel testing which is focused on model outputs, reporting, documentation and internal controls. In August 2018, the FASB issued ASU 2018-13 “Changes to the Disclosure Requirements for Fair Value Measurement” and ASU 2018-14 “Changes to the Disclosure Requirements for Defined Benefit Plans.” These ASUs modify certain disclosure requirements pertaining to fair value measurements and defined benefit plans, respectively, as part of the FASB’s disclosure framework project, and are intended to improve the effectiveness of disclosures in the notes to financial statements. ASU 2018-13 is effective for fiscal years and interim periods within those fiscal years beginning after December 15, 2019. ASU 2018-14 is effective for fiscal years ending after December 15, 2020. Early adoption is permitted. The adoption of these ASUs will modify the Corporation’s disclosures but will not impact its financial position or results of operations.

For purposes of computing EPS, these RSUs were considered to participate with common stock in the earnings of the Corporation and, therefore, the Corporation calculated basic and diluted EPS using the two-class method. Substantially all of the RSUs awarded in 2016 vested on December 31, 2018. As a result, beginning in 2019, the Corporation calculates basic and dilutive EPS using the trea sury stock method.

[1]	Restricted stock units (“RSUs”) awarded in 2016 accrued dividends at the same rate as the dividends declared by the Board of Directors on the Corporation’s common stock. For purposes of computing EPS, these RSUs were considered to participate with common stock in the earnings of the Corporation and, therefore, the Corporation calculated basic and diluted EPS using the two-class method. Substantially all of the RSUs awarded in 2016 vested on December 31, 2018. As a result, beginning in 2019, the Corporation calculates basic and dilutive EPS using the trea sury stock method.
