Summary of Significant Accounti

Summary of Significant Accounting Policies	12 Months Ended
	Dec. 31, 2017
Disclosure Text Block [Abstract]
Summary of Significant Accounting Policies [Text Block]	Note 1 - Summary of Significant Accounting Policies Business ConnectOne Bancorp, Inc. (the “Parent Corporation”) is incorporated under the laws of the State of New Jersey and is a registered bank holding company. The Parent Corporation’s business currently consists of the operation of its wholly-owned subsidiary, ConnectOne Bank (the “Bank” and, collectively with the Parent Corporation and the Parent Corporation’s subsidiaries, the “Company”). The Bank’s subsidiaries include Union Investment Co. (a New Jersey investment company), Twin Bridge Investment Co. (a Delaware investment company), ConnectOne Preferred Funding Corp. (a New Jersey real estate investment trust), Center Financial Group, LLC (a New Jersey financial services company), Center Advertising, Inc. (a New Jersey advertising company), Morris Property Company, LLC, (a New Jersey limited liability company), Volosin Holdings, LLC, (a New Jersey limited liability company), and NJCB Spec-1, LLC (a New Jersey limited liability company). The Bank is a community-based, full-service New Jersey-chartered commercial bank that was founded in 2005. The Bank operates from its headquarters located at 301 Sylvan Avenue in the Borough of Englewood Cliffs, Bergen County, New Jersey and through its twenty other banking offices. Substantially all loans are secured with various types of collateral, including business assets, consumer assets and commercial/residential real estate. Each borrower’s ability to repay its loans is dependent on the conversion of assets, cash flows generated from the borrowers’ business, real estate rental and consumer wages. Basis of Financial Statement Presentation The consolidated financial statements of the Parent Corporation are prepared on an accrual basis and include the accounts of the Parent Corporation and the Company. All significant intercompany accounts and transactions have been eliminated from the accompanying consolidated financial statements. The consolidated financial statements have been prepared in conformity with U.S. generally accepted accounting principles. Segments FASB ASC 28, “Segment Reporting,” requires companies to report certain information about operating segments. The Company is managed as one segment: a community bank. All decisions including but not limited to loan growth, deposit funding, interest rate risk, credit risk and pricing are determined after assessing the effect on the totality of the organization. For example, loan growth is dependent on the ability of the organization to fund this growth through deposits or other borrowings. As a result, the Company is managed as one operating segment. Use of Estimates In preparing the consolidated financial statements, management has made estimates and assumptions that affect the reported amounts of assets and liabilities as of the dates of the consolidated statements of condition and that affect the results of operations for the periods presented. Actual results could differ significantly from those estimates. Cash and Cash Equivalents Cash and cash equivalents include cash, deposits with other financial institutions with maturities of less than 90 days, and federal funds sold. Net cash flows are reported for customer loan and deposit transactions, interest-bearing deposits in other financial institutions, and federal funds purchased and repurchase agreements. Investment Securities The Company accounts for its investment securities in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 320-10-05. Investments are classified into the following categories: (1) held-to-maturity securities, for which the Company has both the positive intent and ability to hold until maturity, which are reported at amortized cost; (2) trading securities, which are purchased and held principally for the purpose of selling in the near term and are reported at fair value with unrealized gains and losses included in earnings; and (3) available-for-sale securities, which do not meet the criteria of the other two categories and which management believes may be sold prior to maturity due to changes in interest rates, prepayment risk, liquidity or other factors, and are reported at fair value, with unrealized gains and losses, net of applicable income taxes, reported as a component of accumulated other comprehensive income, which is included in stockholders’ equity and excluded from earnings. Investment securities are adjusted for amortization of premiums and accretion of discounts as adjustments to interest income, which are recognized on a level yield method without anticipating prepayments, except for mortgage backed securities where prepayments are anticipated. Investment securities gains or losses are determined using the specific identification method. Securities are evaluated on at least a quarterly basis, and more frequently when market conditions warrant such an evaluation, to determine whether a decline in their value is other-than-temporary. FASB ASC 320-10-65 clarifies the interaction of the factors that should be considered when determining whether a debt security is other-than-temporarily impaired. For debt securities, management must assess whether (a) it has the intent to sell the security and (b) it is more likely than not that it will be required to sell the security prior to its anticipated recovery. These steps are done before assessing whether the entity will recover the cost basis of the investment. In instances when a determination is made that an other-than-temporary impairment exists but the investor does not intend to sell the debt security and it is not more likely than not that it will be required to sell the debt security prior to its anticipated recovery, FASB ASC 320-10-65 changed the presentation and amount of the other-than-temporary impairment recognized in the Consolidated Statement of Income. The other-than-temporary impairment is separated into (a) the amount of the total other-than-temporary impairment related to a decrease in cash flows expected to be collected from the debt security (the credit loss) and (b) the amount of the total other-than-temporary impairment related to all other factors. The amount of the total other-than-temporary impairment related to the credit loss is recognized through earnings. The amount of the total other-than-temporary impairment related to all other factors is recognized through other comprehensive income. Loans Held-for-Sale Residential mortgage loans, originated and intended for sale in the secondary market, are carried at the lower of aggregate cost or estimated fair value as determined by outstanding commitments from investors. For these loans originated and intended for sale, gains and losses on loan sales (sale proceeds minus carrying value) are recorded in other income and direct loan origination costs and fees are deferred at origination of the loan and are recognized in other income upon sale of the loan. Other loans held-for-sale are carried at the lower of aggregate cost or estimated fair value. Fair value on these loans is determined based on the terms of the loan, such as interest rate, maturity date, reset term, as well as sales of similar assets. Loans Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are reported at the principal balance outstanding, net of deferred loan fees and costs, and an allowance for loan losses. Interest income is accrued on the unpaid principal balance. Loan origination fees, net of certain direct origination costs, are deferred and recognized in interest income using the level-yield method without anticipating prepayments. Loan segments are defined as a group of loans, which share similar initial measurement attributes, risk characteristics, and methods for monitoring and assessing credit risk. Management has determined that the Company has five segments of loans: commercial, commercial real estate, commercial construction, residential real estate (including home equity) and consumer. Loans that are 90 days past due are placed on nonaccrual and previously accrued interest is reversed and charged against interest income unless the loans is both well-secured and in the process of collection. Past due status is based on the contractual terms of the loan. In all cases, loans are placed on nonaccrual or charged-off at an earlier date if collection of principal or interest is considered doubtful. Nonaccrual loans and loans 90 days or greater past due and still accruing include both smaller balance homogeneous loans that are collectively evaluated for impairment and loans individually evaluated for impairment. All interest accrued but not received for loans placed on nonaccrual are reversed against interest income. Interest received on such loans is accounted for on the cash-basis or cost-recovery method, until qualifying for return to accrual. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured. The policy of the Company is to generally grant commercial, residential and consumer loans to residents and businesses within its New Jersey and New York market area. The borrowers’ abilities to repay their obligations are dependent upon various factors including the borrowers’ income and net worth, cash flows generated by the borrowers’ underlying collateral, value of the underlying collateral, and priority of the lender’s lien on the property. Such factors are dependent upon various economic conditions and individual circumstances beyond the control of the Company. The Company is therefore subject to risk of loss. The Company believes its lending policies and procedures adequately minimize the potential exposure to such risks and that adequate provisions for loan losses are provided for all known and inherent risks. Collateral and/or personal guarantees are required for a large majority of the Company’s loans. Allowance for Loan Losses The allowance for loan losses is a valuation allowance for probable incurred credit losses. Loan losses are charged against the allowance when management believes the uncollectibility of a loan balance is confirmed. Subsequent recoveries, if any, are credited to the allowance. Management estimates the allowance balance required using past loan loss experience, the nature and volume of the portfolio, information about specific borrower situations and estimated collateral values, economic conditions, and other factors. Allocations of the allowance may be made for specific loans, but the entire allowance is available for any loan that, in management’s judgment, should be charged off. The allowance consists of specific and general components. The specific component relates to loans that are individually classified as impaired. A loan is considered impaired when, based on current information and events, it is probable that the Bank will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement. Factors considered by management in determining impairment include payment status and the probability of collecting scheduled principal and interest payments when due. Loans for which the terms have been modified as a concession to the borrower due to the borrower experiencing financial difficulties are considered troubled debt restructurings (“TDR”) and are classified as impaired. The impairment of a loan can be measured at (1) the fair value of the collateral less costs to sell, if the loan is collateral dependent, (2) at the value of expected future cash flows using the loan’s effective interest rate, or (3) at the loan’s observable market price. Generally, the Bank measures impairment of such loans by reference to the fair value of the collateral less costs to sell. Loans that experience minor payment delays and payment shortfall generally are not classified as impaired. Loans $250,000 and over are individually evaluated for impairment. If a loan that is identified as impaired and the individual test results in an impairment, a portion of the allowance is allocated so that the loan is reported, net, at the fair value of collateral less costs to sell if repayment is expected solely from the collateral or at the present value of estimated future cash flows using the loan’s existing rate if the loan is dependent on cash flow. Loans with balances less than $250,000 are collectively evaluated for impairment, and accordingly, are not separately identified for impairment disclosures. Factors considered by management in determining impairment include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record, and the amount of the shortfall in relation to the principal and interest owed. Troubled debt restructurings are separately identified for impairment disclosures and are measured at the present value of estimated future cash flows using the loan’s effective rate at inception. If a troubled debt restructuring is considered to be a collateral dependent loan, the loan is reported, net, at the fair value of the collateral. For troubled debt restructurings that subsequently default, the Company determines the amount of reserve in accordance with the accounting policy for the allowance for loan losses. The general component covers non-impaired loans and is based on historical loss experience adjusted for current factors. The historical loss experience, the primary factor, is determined by loan segment and is based on the actual loss history experienced by the Bank over an actual three year rolling calculation. This actual loss experience is supplemented with other economic factors based on the risks present for each portfolio segment. This actual loss experience is supplemented with the exogenous factor adjustments based on the risks present for each loan category. These exogenous factors (nine total) include consideration of the following: concentrations of credit; delinquency & nonaccrual trends; economic & business conditions including evaluation of the national and regional economies and industries with significant loan concentrations; external factors including legal, regulatory or competitive pressures that may impact the loan portfolio; changes in the experience, ability, or size of the lending staff, management, or board of directors that may impact the loan portfolio; changes in underwriting standards, collection procedures, charge-off practices, or other changes in lending policies and procedures that may impact the loan portfolio; loss and recovery trends; changes in portfolio size and mix; and trends in problem loans. Purchased Credit-Impaired Loans The Company acquires groups of loans in conjunction with mergers, some of which have shown evidence of credit deterioration since origination. These purchased credit-impaired loans are recorded at their estimated fair value, such that there is no carryover of the seller’s allowance for loan losses. After acquisition, losses are recognized by an increase in the allowance for loan losses. Such purchased credit-impaired loans (“PCI”) are identified on an individual basis. The Company estimates the amount and timing of expected cash flows for each loan and the expected cash flows in excess of amount paid is recorded as interest income over the remaining life of the loan (accretable yield). The excess of the loan’s contractual principal and interest over expected cash flows is not recorded (nonaccretable difference). A PCI loan may be resolved either through a sale of the loan, by working with the customer and obtaining partial or full repayment, by short sale of the collateral, or by foreclosure. A gain or loss on resolution would be recognized based on the difference between the proceeds received and the carrying amount of the loan. PCI loans that met the criteria for nonaccrual may be considered performing, regardless of whether the customer is contractually delinquent, if management can reasonably estimate the timing and amount of the expected cash flows on such loans and if management expects to fully collect the new carrying value of the loans. As such, management may no longer consider the loans to be nonaccrual or nonperforming and may accrue interest on these loans, including the impact of any accretable discount. Derivatives The Company records cash flow hedges at the inception of the derivative contract based on the Company’s intentions and belief as to likely effectiveness as a hedge. Cash flow hedges represent a hedge of a forecasted transaction or the variability of cash flows to be received or paid related to a recognized asset or liability. For a cash flow hedge, the gain or loss on the derivative is reported in other comprehensive income and is reclassified into earnings in the same periods during which the hedged transaction affects earnings. The changes in the fair value of derivatives that are not highly effective in hedging the changes in fair value or expected cash flows of the hedged item are recognized immediately in current earnings. Changes in the fair value of derivatives that do not qualify for hedge accounting are reported currently in earnings, as noninterest income. Net cash settlements on derivatives that qualify for hedge accounting are recorded in interest income or interest expense, based on the item being hedged. Net cash settlements on derivatives that do not qualify for hedge accounting are reported in noninterest income. Cash flows on hedges are classified in the cash flow statement the same as the cash flows of the items being hedged. The Company formally documents the relationship between derivatives and hedged items, as well as the risk-management objective and the strategy for undertaking hedge transactions at the inception of the hedging relationship. This documentation includes linking cash flow hedges to specific assets and liabilities on the balance sheet or to specific firm commitments or forecasted transactions. The Company also formally assesses, both at the hedge’s inception and on an ongoing basis, whether the derivative instruments that are used are highly effective in offsetting changes in fair values or cash flows of the hedged items. The Company discontinues hedge accounting when it determines that the derivative is no longer effective in offsetting changes in the fair value or cash flows of the hedged item, the derivative is settled or terminates, a hedged forecasted transaction is no longer probable, a hedged firm commitment is no longer firm, or treatment of the derivative as a hedge is no longer appropriate or intended. When hedge accounting is discontinued, subsequent changes in fair value of the derivative are recorded as noninterest income. When a cash flow hedge is discontinued but the hedged cash flows or forecasted transactions are still expected to occur, gains or losses that were accumulated in other comprehensive income are amortized into earnings over the same periods which the hedged transactions will affect earnings. Restricted Stock The Bank is a member of the Federal Home Loan Bank (“FHLB”) of New York. Members are required to own a certain amount of stock based on the level of borrowings and other factors, and may invest in additional amounts. FHLB stock is carried at cost, classified as a restricted security, and periodically evaluated for impairment based on ultimate recovery of par value. Cash dividends on the stock are reported as income. Transfers of Financial Assets Transfers of financial assets are accounted for as sales, when control over the assets has been relinquished. Control over transferred assets is deemed to be surrendered when the assets have been isolated from the Company, 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 the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity. Premises and Equipment Land is carried at cost and premises and equipment are stated at cost less accumulated depreciation. Buildings and related components are depreciated using the straight-line method with useful lives ranging from 4 to 39 years. Furniture, fixtures and equipment are depreciated using the straight-line (or accelerated) method with useful lives ranging from 3 to 10 years. Other Real Estate Owned Other real estate owned (“OREO”), representing property acquired through foreclosure and held-for-sale, is initially recorded at fair value less cost to sell at the date of foreclosure, establishing a new cost basis. Subsequently, valuations are periodically performed by management and the assets are carried at the lower of carrying amount or fair value less cost to sell. Costs relating to holding the assets are charged to expenses. Employee Benefit Plans The Company has a noncontributory pension plan that covered all eligible employees up until September 30, 2007, at which time the Company froze its defined benefit pension plan. As such, all future benefit accruals in this pension plan were discontinued and all retirement benefits that employees would have earned as of September 30, 2007 were preserved. The Company’s policy is to fund at least the minimum contribution required by the Employee Retirement Income Security Act of 1974. The costs associated with the plan are accrued based on actuarial assumptions and included in salaries and employee benefits expense. The Company accounts for its defined benefit pension plan in accordance with FASB ASC 715-30. FASB ASC 715-30 requires that the funded status of defined benefit postretirement plans be recognized on the Company’s statement of financial condition and changes in the funded status be reflected in other comprehensive income. FASB ASC 715-30 also requires companies to measure the funded status of the plan as of the date of its fiscal year-end. The Company maintains a 401(k) employee savings plan to provide for defined contributions which covers substantially all employees of the Company. Employee 401(k) and profit sharing plan expense is the amount of matching contributions. Stock-Based Compensation Stock compensation accounting guidance (FASB ASC 718, “Compensation-Stock Compensation”) requires that the compensation cost related to share-based payment transactions be recognized in financial statements. That cost will be measured based on the grant date fair value of the equity or liability instruments issued. The stock compensation accounting guidance covers a wide range of share-based compensation arrangements including stock options, restricted share plans, performance-based awards, share appreciation rights and employee share purchase plans. Stock compensation accounting guidance requires that compensation cost for all stock awards be calculated and recognized over the employees’ service period, generally defined as the vesting period. For awards with graded-vesting, compensation cost is recognized on a straight-line basis over the requisite service period for the entire award. A Black-Scholes model is used to estimate the fair value of stock options while the market price of the Company’s common stock at the date of grant is used for restricted stock awards. See Note 19 of the Notes to Consolidated Financial Statements for a further discussion. Treasury Stock Subject to limitations applicable to the Parent Corporation, treasury stock purchases may be made from time to time as, in the opinion of management, market conditions warrant, in the open market or in privately negotiated transactions. Shares repurchased are added to the corporate treasury and will be used for future stock dividends and other issuances. The repurchased shares are recorded as treasury stock, which results in a decrease in stockholders’ equity. Treasury stock is recorded using the cost method and accordingly is presented as a reduction of stockholders’ equity. During the years ended December 31, 2017, 2016 and 2015, the Parent Corporation did not purchase any of its shares. Goodwill Goodwill arises from business combinations and is generally determined as of the excess of the fair value of the consideration transferred, plus the fair value of any noncontrolling interests in the acquiree, over the fair value of the net assets acquired and liabilities assumed as of the acquisition date. Goodwill and intangible assets acquired in a purchase business combination and determined to have an indefinite useful life are not amortized, but tested for impairment annually or more frequently if events and circumstances exists that indicate that a goodwill impairment test should be performed. The Company has selected December 31, as the date to perform the annual impairment test. No impairment charge was deemed necessary for the years ended December 31, 2017, 2016 and 2015. Other Intangible Assets Other intangible assets consist of core deposits arising from business combinations that are amortized over their estimated useful lives to their estimated residual value. Comprehensive Income Total comprehensive income includes all changes in equity during a period from transactions and other events and circumstances from nonowner sources. The Company’s other comprehensive income is comprised of unrealized holding gains and losses on securities available-for-sale, unrecognized actuarial gains and losses of the Company’s defined benefit pension plan and unrealized gains and losses on cash flow hedges, net of taxes. Restrictions on Cash Cash on hand or on deposit with the Federal Reserve Bank is required to meet regulatory reserve and clearing requirements. Dividend Restriction Banking regulations require maintaining certain capital levels and may limit the dividends paid by the Bank to the Parent Corporation or by the Parent Corporation to the stockholders. Fair Value of Financial Instruments Fair values of financial instruments are estimated using relevant market information and other assumptions, as more fully disclosed in a separate note. Fair value estimates involve uncertainties and matters of significant judgment regarding interest rates, credit risk, prepayments, and other factors, especially in the absence of broad markets for particular items. Changes in assumptions or in market conditions could significantly affect the estimates. Bank Owned Life Insurance The Company invests in Bank Owned Life Insurance (“BOLI”) to help offset the cost of employee benefits. The change in the cash surrender value of the BOLI is recorded as a component of noninterest income. Income Taxes Income tax expense is the total of the current year income tax due or refundable and the change in deferred tax assets and liabilities. Deferred tax assets and liabilities are the expected future tax amounts for the temporary differences between carrying amounts and tax bases of assets and liabilities, computed using enacted tax rates. A valuation allowance, if needed, reduces deferred tax assets to the amount expected to be realized. A tax position is recognized as a benefit only if it is “more likely than not” that the tax position would be sustained in a tax examination, with a tax examination being presumed to occur. 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. Advertising Costs The Company recognizes its marketing and advertising cost as incurred. Reclassifications Certain reclassifications have been made in the consolidated financial statements and footnotes for 2016 and 2015 to conform to the classifications presented in 2017. Such reclassifications had no impact on net income or stockholders’ equity.

Earnings Per Share [Abstract]
Earnings per Common Share	Note 3. Earnings per Common Share Financial Accounting Standards Board Accounting Standards Codification (“FASB ASC”) No. 260-10-45 addresses whether instruments granted in share-based payment transactions are participating securities prior to vesting and, therefore, need to be included in the earnings allocation in computing earnings per share (“EPS”). The restricted stock awards and certain restricted stock units granted by the Company contain non-forfeitable rights to dividends and therefore are considered participating securities. The two-class method for calculating basic EPS excludes dividends paid to participating securities and any undistributed earnings attributable to participating securities. Earnings per common share have been computed based on the following: Years Ended December 31, 2017 2016 2015 (in thousands, except per share amounts) Net income available to common stockholders $ 43,220 $ 31,060 $ 41,199 Earnings allocated to participating securities (141) (147) (157) Income attributable to common stock $ 43,079 $ 30,913 $ 41,042 Weighted average common shares outstanding, including participating securities 31,943 30,453 29,989 Weighted average participating securities (41) (54) (51) Weighted average common shares outstanding 31,902 30,399 29,938 Incremental shares from assumed conversions of options, performance units and restricted shares 335 291 346 Weighted average common and equivalent shares outstanding 32,237 30,690 30,284 Earnings per common share: Basic $ 1.35 $ 1.02 $ 1.37 Diluted 1.34 1.01 1.36 There were no antidilutive common share equivalents as of December 31, 2017, 2016 and 2015.

Investments, Debt and Equity Securities [Abstract]
Investments in Debt and Marketable Equity Securities (and Certain Trading Assets) Disclosure [Text Block]	Note 4 - Investment Securities The Company’s investment securities are classified as available-for-sale at December 31, 2017 and December 31, 2016. Investment securities available-for-sale are reported at fair value with unrealized gains or losses included in stockholders’ equity, net of tax. Accordingly, the carrying value of such securities reflects their fair value as of December 31, 2017 and December 31, 2016. Fair value is based upon either quoted market prices, or in certain cases where there is limited activity in the market for a particular instrument, assumptions are made to determine their fair value. See Note 22 of the Notes to Consolidated Financial Statements for a further discussion. Transfers of debt securities from the held-to-maturity category to the available-for-sale category are made at fair value at the date of transfer. For transfers from the available-for-sale category to the held-to maturity category the unrealized holding gain or loss at the date of transfer remains in accumulated other comprehensive income, a component of stockholders’ equity and in the carrying value of the held-to-maturity investment security. Unrealized holding gains or losses that remain in accumulated other comprehensive income are amortized or accreted out of other comprehensive income with an offsetting entry to interest income as a yield adjustment through earnings over the remaining terms of the securities. For transfers from the held-to-maturity category to the available-for-sale category unrealized holding gain or loss at the date of the transfer shall be recognized in accumulated other comprehensive income, net of tax. During the year ended December 31, 2016, the Company transferred all securities previously categorized as held-to-maturity to available-for-sale classification. The transfer resulted in an increase of approximately $210 million in amortized cost basis of available-for-sale securities and resulted in a net increase to accumulated other comprehensive income of $7.4 million, net of tax. The transfer enhanced liquidity and increased flexibility with regard to asset-liability management and balance sheet composition. As a result of the transfer, the Company believes it has tainted its held-to-maturity classification and judgment will be required in the future in determining when circumstances have changed such that management can assert that it has the intent and ability to hold debt securities to maturity. Based on this guidance, the Company does not expect to classify any securities as held-to-maturity within the near future. The following tables present information related to the Company’s portfolio of securities available-for-sale and held-to-maturity at December 31, 2017 and 2016. Amortized Gross Gross Fair (dollars in thousands) December 31, 2017 Investment securities available-for-sale Federal agency obligations $ 56,297 $ 141 $ (416) $ 56,022 Residential mortgage pass-through securities 183,509 330 (1,948) 181,891 Commercial mortgage pass-through securities 4,054 3 (3) 4,054 Obligations of U.S. states and political subdivisions 130,723 1,739 (1,334) 131,128 Trust preferred securities 4,577 205 (111) 4,671 Corporate bonds and notes 29,801 163 (271) 29,693 Asset-backed securities 12,021 66 (37) 12,050 Certificates of deposit 621 4 - 625 Equity securities 11,843 235 (350) 11,728 Other securities 3,422 - - 3,422 Total securities available-for-sale $ 436,868 $ 2,886 $ (4,470) $ 435,284 Amortized Gross Gross Fair December 31, 2016 (dollars in thousands) Investment securities available-for-sale Federal agency obligations $ 52,826 $ 282 $ (271) $ 52,837 Residential mortgage pass-through securities 72,922 519 (944) 72,497 Commercial mortgage pass-through securities 4,186 23 - 4,209 Obligations of U.S. states and political subdivisions 148,747 2,789 (931) 150,605 Trust preferred securities 5,575 242 (151) 5,666 Corporate bonds and notes 36,717 586 (375) 36,928 Asset-backed securities 14,867 2 (286) 14,583 Certificates of deposit 973 10 - 983 Equity securities 11,843 192 (325) 11,710 Other securities 3,272 - - 3,272 Total securities available-for-sale $ 351,928 $ 4,645 $ (3,283) $ 353,290 Investment securities having a carrying value of approximately $157.8 million and $121.9 million at December 31, 2017 and December 31, 2016, respectively, were pledged to secure public deposits, borrowings, repurchase agreements, Federal Reserve Discount Window borrowings and Federal Home Loan Bank advances and for other purposes required or permitted by law. As of December 31, 2017 and December 31, 2016, there were no holdings of securities of any one issuer, other than the U.S. Government and its agencies, in an amount greater than 10% of stockholders’ equity. The following table presents information for investments in securities available-for-sale at December 31, 2017, based on scheduled maturities. Actual maturities can be expected to differ from scheduled maturities due to prepayment or early call options of the issuer. Securities not due at a single maturity date are shown separately. December 31, 2017 Amortized Fair (dollars in thousands) Investment Securities Available-for-Sale: Due in one year or less $ 7,964 $ 7,985 Due after one year through five years 28,056 28,294 Due after five years through ten years 39,646 40,069 Due after ten years 158,374 157,841 Residential mortgage pass-through securities 183,509 181,891 Commercial mortgage pass-through securities 4,054 4,054 Equity securities 11,843 11,728 Other securities 3,422 3,422 Total securities available-for-sale $ 436,868 $ 435,284 Gross gains and losses from the sales, calls, and maturities of investment securities for the years ended December 31, 2017, 2016 and 2015 were as follows: Years Ended December 31, 2017 2016 2015 (dollars in thousands) Proceeds $ 29,543 $ 85,253 $ 65,231 Gross gains on sales of investment securities 1,596 $ 4,234 $ 3,931 Gross losses on sales of investment securities - - - Net gains on sales of investment securities 1,596 4,234 3,931 Less: tax provision on net gains (579) (1,682) (1,564) Net gains on sales of investment securities, after tax $ 1,017 $ 2,552 $ 2,367 Other-than-Temporarily Impaired Investments The Company reviews all securities for potential recognition of other-than-temporary impairment. The Company maintains a watch list for the identification and monitoring of securities experiencing problems that require a heightened level of review. This could include credit rating downgrades. The Company’s assessment of whether an impairment in the portfolio is other-than temporary includes factors such as whether the issuer has defaulted on scheduled payments, announced a restructuring and/or filed for bankruptcy, has disclosed severe liquidity problems that cannot be resolved, disclosed deteriorating financial condition or sustained significant losses. Temporarily Impaired Investments The Company does not believe that any of the unrealized losses, which were comprised of 112 and 84 investment securities as of December 31, 2017 and December 31, 2016, respectively, represent an other-than-temporary impairment. The gross unrealized losses associated with U.S. Treasury and agency securities, federal agency obligations, mortgage-backed securities, corporate bonds, tax-exempt securities, asset-backed securities, trust preferred securities, mutual funds and equity securities are not considered to be other-than-temporary because management believes these unrealized losses are related to changes in interest rates and do not affect the expected cash flows of the underlying collateral or issuer. Factors which may contribute to unrealized losses include credit risk, market risk, changes in interest rates, economic cycles, and liquidity risk. The magnitude of any unrealized loss may be affected by the relative concentration of the Company’s investment in any one issuer or industry. The Company has established policies to reduce exposure through diversification of the investment portfolio including limits on concentrations to any one issuer. The Company believes the investment portfolio is prudently diversified. The unrealized losses included in the tables below are primarily related to changes in interest rates and credit spreads. All of the Company’s investment securities are performing and are expected to continue to perform in accordance with their respective contractual terms and conditions. These are largely intermediate duration holdings and, in certain cases, monthly principal payments can further reduce loss exposure resulting from an increase in rates. The Company evaluates all securities with unrealized losses quarterly to determine whether the loss is other-than-temporary. Unrealized losses in the corporate debt securities category consist primarily of senior unsecured corporate debt securities issued by large financial institutions, insurance companies and other corporate issuers. Single issuer corporate trust preferred securities are also included, and in the case of one holding the market valuation loss is largely based upon the floating rate coupon and corresponding market valuation. Neither that trust preferred issuer, nor any other corporate issuers, have defaulted on interest payments. The unrealized loss in equity securities consists of losses on other bank equities. The decline in fair value is due in large part to the lack of an active trading market for these securities, changes in market credit spreads and rating agency downgrades. Management concluded that these securities were not other-than-temporarily impaired at December 31, 2017. In determining whether or not securities are OTTI, the Company must exercise considerable judgment. Accordingly, there can be no assurance that the actual results will not differ from the Company’s judgments and that such differences may not require the future recognition of other-than-temporary impairment charges that could have a material effect on the Company’s financial position and results of operations. In addition, the value of, and the realization of any loss on, an investment security is subject to numerous risks as cited above. The following tables indicate gross unrealized losses not recognized in income and fair value, aggregated by investment category and the length of time individual securities have been in a continuous unrealized loss position at December 31, 2017 and 2016. There were no investments held-to-maturity as of December 31, 2017 and 2016.

Loans, Notes, Trade and Other Receivables Disclosure	Note 5 - Loans and the Allowance for Loan Losses Loans Receivable: 2017 2016 (dollars in thousands) Commercial $ 824,082 $ 553,576 Commercial real estate 2,592,909 2,204,710 Commercial construction 483,216 486,228 Residential real estate 271,795 232,547 Consumer 2,808 2,380 Gross loans 4,174,810 3,479,441 Net deferred fees (3,354) (3,609) Loans receivable $ 4,171,456 $ 3,475,832 At December 31, 2017 and 2016, loan balances of approximately $1.9 billion and $1.7 billion, respectively, were pledged to secure borrowings from the Federal Home Loan Bank. The loan segments in the above table have unique risk characteristics with respect to credit quality: · The repayment of commercial loans is generally dependent on the creditworthiness and cash flow of borrowers, and if applicable, guarantors, which may be negatively impacted by adverse economic conditions. While the majority of these loans are secured, collateral type, marketing, coverage, valuation and monitoring is not as uniform as in other portfolio classes and recovery from liquidation of such collateral may be subject to greater variability. · Payment on commercial mortgages is driven principally by operating results of the managed properties or underlying business and secondarily by the sale or refinance of such properties. Both primary and secondary sources of repayment, and value of the properties in liquidation, may be affected to a greater extent by adverse conditions in the real estate market or the economy in general. · Properties underlying construction, land and land development loans often do not generate sufficient cash flows to service debt and thus repayment is subject to ability of the borrower and, if applicable, guarantors, to complete development or construction of the property and carry the project, often for extended periods of time. As a result, the performance of these loans is contingent upon future events whose probability at the time of origination is uncertain. · The ability of borrowers to service debt in the residential and consumer loan portfolios is generally subject to personal income which may be impacted by general economic conditions, such as increased unemployment levels. These loans are predominately collateralized by first and/or second liens on single family properties. If a borrower cannot maintain the loan, the Company’s ability to recover against the collateral in sufficient amount and in a timely manner may be significantly influenced by market, legal and regulatory conditions. Loans Held-For-Sale: 2017 2016 (dollars in thousands) Commercial $ - $ 70,105 Commercial real estate 24,475 7,712 Residential mortgage loans 370 188 Total carrying amount $ 24,845 $ 78,005 As of December 31, 2016, the commercial loans held-for-sale segment included the Company’s entire taxi medallion portfolio, with a carrying value of $65.6 million (with an unpaid principal balance of $102.1 million). During the fourth quarter of 2017, the Bank’s entire taxi medallion loan portfolio was transferred back to loans held-for-investment from the held-for-sale designation. As of December 31, 2017, the loans secured by NYC taxi medallions, predominantly corporate medallions, had a carrying value of $46.8 million, compared to $65.6 million as of December 31, 2016.

The $36.7 million charge on the taxi medallion portfolio occurred in conjunction with the transfer of the taxi medallion loans to loans held-for-sale. The amount transferred to loans held-for-sale as of December 31, 2016 had a carrying value of $65.6 million following the charge-off. Troubled Debt Restructurings Loans are considered to have been modified in a troubled debt restructuring (“TDRs”) when due to a borrower’s financial difficulties, the Company makes certain concessions to the borrower that it would not otherwise consider. Modifications may include interest rate reductions, principal or interest forgiveness, forbearance, and other actions intended to minimize economic loss and to avoid foreclosure or repossession of collateral. Generally, a nonaccrual loan that has been modified in a troubled debt restructuring remains on nonaccrual status for a period of six months to demonstrate that the borrower is able to meet the terms of the modified loan. However, performance prior to the modification, or significant events that coincide with the modification, are included in assessing whether the borrower can meet the new terms and may result in the loan being returned to accrual status at the time of loan modification or after a shorter performance period. If the borrower’s ability to meet the revised payment schedule is uncertain, the loan remains on nonaccrual status. At December 31, 2017, there were no commitments to lend additional funds to borrowers whose loans were on nonaccrual status or were contractually past due 90 days or greater and still accruing interest, or whose terms have been modified in troubled debt restructurings. The following table presents loans by segment modified as troubled debt restructurings and the related changes to the allowance for loan and leases losses that occurred during the year ended December 31, 2017 and December 31, 2016: December 31, 2017 December 31, 2016 (dollars in thousands) Recorded Investment ALLL Recorded Investment ALLL Troubled debt restructurings Balance January 1, $ 13,818 $ - $ 86,629 $ 4,500 Additions 10,378 - 26,325 8,250 Payoffs/paydowns (3,098) (2,616) Transfers (580) - (96,520) - Other - - - (12,750) Balance December 31, $ 20,518 $ - $ 13,818 $ - TDRs totaled $20.5 million at December 31, 2017, of which $5.6 million were on nonaccrual status and $14.9 million were performing under restructured terms. At December 31, 2016, TDRs totaled $13.8 million, of which $0.5 million were on nonaccrual status and $13.3 million were performing under restructured terms. As of December 31, 2017, the taxi medallion loans that were modified in a troubled debt restructuring in 2016 and 2015 were transferred back to the loans held-for-investment category from the loans held-for-sale category.

The modifications consisted of a deferral of principal amortization from approximately 25-30 year amortization to interest-only. There was no extension of the loans’ contractual maturity dates, there was no forgiveness of principal, and the interest rates on these loans were increased from approximately 3%-3.25% to 3.75%. These loans were accruing prior to modification and remained in accrual status post-modification. There were no charge-offs in connection with a loan modification at the time of modification during the year ended December 31, 2015. There were no troubled debt restructurings for which there was a payment default within twelve months following the modification during the year ended December 31, 2015.

Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill and Intangible Assets Disclosure [Text Block]	Note 7 - Goodwill and Other Intangible Assets A goodwill impairment test is required under ASC 350, Intangibles – Goodwill and Other, and the FASB issued ASU No. 2011-08, “Testing Goodwill for Impairment,” allowing an initial qualitative assessment of goodwill commonly known as step zero impairment testing. In general, the step zero test allows an entity to first assess qualitative factors to determine whether it is more likely than not (i.e., more than 50%) that the fair value of a reporting unit is less than its carrying value. If a step zero impairment test results in the conclusion that it is more likely than not that the fair value of the reporting unit exceeds its carrying value, then no further testing is required.

Three of the FHLB notes ($2.5 million and $7.5 million each due April 2, 2018, and $5.0 million due July 16, 2018) contain a convertible option which allows the FHLB, at quarterly intervals, to convert the fixed convertible advance into replacement funding for the same or lesser principal based on any advance then offered by the FHLB at its current market rate. The Company has the option to repay these advances, if converted, without penalty. The remaining advances are payable at stated maturity, with a prepayment penalty for fixed rate advances. All FHLB advances are fixed rate. The advances at December 31, 2017 were primarily collateralized by approximately $1.5 billion of commercial mortgage loans, net of required over collateralization amounts, under a blanket lien arrangement. At December 31, 2017 the Company had remaining borrowing capacity of approximately $829 million with the FHLB.

Securities Sold under Agreements to Repurchase [Text Block]	Note 10 – Securities Sold under Agreements to Repurchase The Company has entered into agreements under which it has sold securities subject to an obligation to repurchase the same or similar securities. Under these arrangements, the Company may transfer legal control over the assets but still retain effective control through an agreement that both entitles and obligates the Company to repurchase the assets. The obligation to repurchase the securities is reflected as a liability in the Company’s consolidated statement of condition, while the securities underlying the securities sold under agreements to repurchase remain in the respective asset accounts and are delivered to and held as collateral by third party trustees. Repurchase agreements are secured borrowings. The Company pledges investment securities to secure those borrowings. Information concerning repurchase agreements is summarized as follows: 2017 2016 2015 (dollars in thousands) Average daily balance during the year $ 6,781 $ 15,000 $ 22,890 Average interest rate during the year 5.95 % 5.95 % 5.92 % Maximum month-end balance during the year $ 15,000 $ 15,000 $ 31,000 Weighted average interest rate during the year 5.95 % 5.95 % 5.92 % The table below shows the remaining contractual maturity of repurchase agreements by fair value of collateral pledged: December 31, 2017 Remaining Contractual Maturity of the Agreements Overnight and Continuous Up to 30 30-90 Days Greater Than 90 Days Total Repurchase agreements and repurchase-to-maturity transactions: U.S. Treasury and agency securities $ - $ - $ - $ - $ - Residential mortgage pass-through securities - - - - - Total Borrowings $ - $ - $ - $ - $ - Amounts related to repurchase agreements not included in offsetting disclosure in Note 13. $ - December 31, 2016 Remaining Contractual Maturity of the Agreements (dollars in thousands) Overnight and Continuous Up to 30 30-90 Days Greater Than 90 Days Total Repurchase agreements and repurchase-to-maturity transactions: U.S. Treasury and agency securities $ - $ - $ - $ - $ - Residential mortgage pass-through securities - - - 16,826 16,826 Total Borrowings $ - $ - $ - $ 16,826 $ 16,826 Amounts related to agreements not included in offsetting disclosure in Note 13. $ 1,826 The fair value of securities pledged to secure repurchase agreements may decline.

Subordinated Debentures	Note 11 - Subordinated Debentures During 2003, the Company formed a statutory business trust, which exists for the exclusive purpose of (i) issuing Trust Securities representing undivided beneficial interests in the assets of the Trust; (ii) investing the gross proceeds of the Trust securities in junior subordinated deferrable interest debentures (subordinated debentures) of the Company; and (iii) engaging in only those activities necessary or incidental thereto. On December 19, 2003, Center Bancorp Statutory Trust II, a statutory business trust and wholly-owned subsidiary of the Parent Corporation issued $5.0 million of, MMCapS capital securities to investors due on January 23, 2034. The capital securities presently qualify as Tier 1 capital. The trust loaned the proceeds of this offering to the Company and received in exchange $5.2 million of the Parent Corporation’s subordinated debentures. The subordinated debentures are redeemable in whole or in part prior to maturity. The floating interest rate on the subordinate debentures is three-month LIBOR plus 2.85% and reprices quarterly. The rate at December 31, 2017 was 4.23%. These subordinated debentures and the related income effects are not eliminated in the consolidated financial statements as the statutory business trust is not consolidated in accordance with FASB ASC 810-10. Distributions on the subordinated debentures owned by the subsidiary trust have been classified as interest expense in the Consolidated Statements of Income. The following table summarizes the mandatory redeemable trust preferred securities of the Company’s Statutory Trust II at December 31, 2017 and December 31, 2016. Issuance Date Securities Liquidation Value Coupon Rate Maturity Redeemable by 12/19/2003 $ 5,000,000 $1,000 per Capital Security Floating 3-month LIBOR + 285 Basis Points 01/23/2034 01/23/2009 In June 2015, the Parent Corporation issued $50.0 million in aggregate principal amount of fixed-to-floating rate subordinated notes (the “Notes”). The Notes are non-callable for five years, have a stated maturity of July 1, 2025, and bear interest at a fixed rate of 5.75% per year, from and including June 30, 2015 to, but excluding July 1, 2020. From and including July 1, 2020 to the maturity date or early redemption date, the interest rate will reset quarterly to a level equal to the then current three-month LIBOR rate plus 393 basis points. As of December 31, 2017, unamortized costs related to the debt issuance were $456,000.

Income Tax Disclosure	Note 12 - Income Taxes The current and deferred amounts of income tax expense for 2017, 2016 and 2015 are as follows: 2017 2016 2015 Current: (dollars in thousands) Federal $ 21,090 $ 10,173 $ 22,512 State 505 (366) 907 Subtotal 21,595 9,807 23,419 Deferred: Federal 3,876 2,682 (3,835) State (177) (713) 342 Subtotal 3,699 1,969 (3,493) Income tax expense $ 25,294 $ 11,776 $ 19,926 The Tax Reform Act was signed into law on December 22, 2017. Pursuant to the Securities and Exchange Commission Staff Accounting Bulletin No. 118, Income Tax Accounting Implications of the Tax Cuts and Jobs Act (“SAB 118”), given the amount and complexity of the changes in tax law resulting from the Tax Reform Act, the Company has not finalized the accounting for the income tax effects of the Tax Reform Act. This includes the re-measurement of deferred taxes. The impact of the Tax Reform Act may differ from this estimate, during the one-year measurement period due to, among other things, further refinement of the Company’s calculations, changes in interpretations and assumptions the Company has made, guidance that may be issued and actions the Company may take as a result of the Tax Reform Act. As a result of the Tax Reform Act, the Company recorded a tax charge of approximately $5.6 million primarily due to a re-measurement of deferred tax assets and liabilities. Actual income tax expense differs from the tax computed based on pre-tax income and the applicable statutory federal tax rate for the following reasons: 2017 2016 2015 (dollars in thousands) Income before income tax expense $ 68,514 $ 42,858 $ 61,237 Federal statutory rate 35 % 35 % 35% Computed “expected” Federal income tax expense 23,980 15,000 21,433 State tax, net of federal tax benefit 213 (701) 812 Impact of Tax Reform Act 5,623 - - Bank owned life insurance (1,113) (896) (624) Tax-exempt interest and dividends (2,123) (1,714) (1,584) Tax benefits from stock based compensation (348) - - Other, net (938) 87 (111) Income tax expense $ 25,294 $ 11,776 $19,926 The tax effects of temporary differences that give rise to significant portions of the deferred tax asset and deferred tax liability at December 31, 2017 and 2016 are presented in the following table: 2017 2016 Deferred tax assets: (dollars in thousands) Allowance for loan losses 8,848 10,374 Purchase accounting 2,310 4,881 Pension actuarial losses 1,647 2,439 New Jersey net operating loss 1,310 1,004 Deferred compensation 1,184 2,277 Unrealized losses on securities and swaps 483 - Deferred loan costs, net of fees 474 613 Accrued rent 459 617 Capital lease 211 139 Nonaccrual interest 158 470 Other 7 14 Total deferred tax assets $ 17,091 $ 22,828 Deferred tax liabilities: Employee benefit plans $ (1,501) $ (2,275) Depreciation (434) (1,039) Prepaid expenses (174) (345) Market discount accretion (60) (235) Unrealized gains on securities and swaps (224) (449) Other (28) (33) Total deferred tax liabilities (2,421) (4,376) Net deferred tax assets $ 14,670 $ 18,452 In assessing the realization of 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 for state purposes is dependent upon the generation of future taxable income during periods in which those temporary differences become deductible, while for Federal purposes the deferred tax assets can also be realized through tax carrybacks. Management considers the scheduled reversal of deferred tax liabilities, the projected future taxable income, and tax planning strategies in making this assessment. During 2017 and 2016, based on the level of historical taxable income and projections for future taxable income over the periods in which the deferred tax assets are deductible, the Company believes the net deferred tax assets are more likely than not to be realized. There are no unrecorded tax benefits and the Company does not expect the total amount of unrecognized income tax benefits to significantly increase in the next twelve months. The Company’s federal income tax returns are open and subject to examination from the 2014 tax return year and forward. The Company’s state income tax returns are generally open from the 2013 and later tax return years based on individual state statutes of limitations.

Offsetting [Abstract]
Offsetting Assets and Liabilities [Text Block]	Note 13 – Offsetting Assets and Liabilities Certain financial instrument-related assets and liabilities may be eligible for offset on the consolidated statements of condition because they are subject to master netting agreements or similar agreements. However, the Company does not elect to offset such arrangements on the consolidated financial statements. The Company enters into interest rate swap agreements with financial institution counterparties. For additional detail regarding interest rate swap agreements refer to Note 21 within this section. In the event of default on, or termination of, any one contract, both parties have the right to net settle multiple contracts. Also, certain interest rate swap agreements may require the Company to receive or pledge cash or financial instrument collateral based on the contract provisions. The Company also entered into an agreement to sell securities subject to an obligation to repurchase the same or similar securities, referred to as a repurchase agreement. Under this agreement, the Company may transfer legal control over the assets but still retain effective control through an agreement that both entitles and obligates the Company to repurchase the assets. The obligation to repurchase the securities is reflected as a liability in the Company’s consolidated statement of condition, while the securities underlying the repurchase agreements remain in the respective investment securities account, therefore there is no offsetting or netting of the investment securities assets with the repurchase agreement liability. The following table presents information about financial instruments that are eligible for offset as of December 31, 2017 and December 31, 2016: Gross Amounts Not Offset Gross Gross Amounts Net Amounts Financial Cash or Net (dollars in thousands) December 31, 2017 Assets: Interest rate swaps $ 798 $ - $ 798 $ - $ - $ 798 Liabilities: Repurchase agreements $ - $ - $ - $ - $ - $ - December 31, 2016 Assets: Interest rate swaps $ 88 $ - $ 88 $ - $ - $ 88 Liabilities: Repurchase agreements $ 15,000 $ - $ 15,000 $ - $ 15,000 $ - For the year ended December 31, 2017 and 2016 there was no financial collateral pledged to our interest rate swaps.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies Disclosure	Note 14 - Commitments, Contingencies and Concentrations of Credit Risk In the normal course of business, the Company has outstanding commitments and contingent liabilities, such as standby and commercial letters of credit, unused portions of lines of credit and commitments to extend various types of credit. Commitments to extend credit and standby letters of credit generally do not exceed one year. These financial instruments involve, to varying degrees, elements of credit risk in excess of the amounts recognized in the consolidated financial statements. The commitment or contract amount of these financial instruments is an indicator of the Company’s level of involvement in each type of instrument as well as the exposure to credit loss in the event of nonperformance by the other party to the financial instrument. The Company controls the credit risk of these financial instruments through credit approvals, limits and monitoring procedures. To minimize potential credit risk, the Company generally requires collateral and other credit-related terms and conditions from the customer. In the opinion of management, the financial condition of the Company will not be materially affected by the final outcome of these commitments and contingent liabilities. A substantial portion of the Bank’s loans are secured by real estate located in New Jersey and New York. Accordingly, the collectability of a substantial portion of the loan portfolio of the Bank is susceptible to changes in the metropolitan New York real estate market. The following table provides a summary of financial instruments with off-balance sheet risk at December 31, 2017 and 2016: 2017 2016 (dollars in thousands) Commitments under commercial loans and lines of credit $ 344,142 $ 267,865 Home equity and other revolving lines of credit 44,483 52,788 Outstanding commercial mortgage loan commitments 254,710 263,395 Standby letters of credit 34,114 18,331 Overdraft protection lines 688 733 Total $ 678,137 $ 603,112 The Company is subject to claims and lawsuits that arise in the ordinary course of business. Based upon the information currently available in connection with such claims, it is the opinion of management that the disposition or ultimate determination of such claims will not have a material adverse impact on the consolidated financial position, results of operations, or liquidity of the Company.

Stockholders' Equity Note [Abstract]
Stockholders' Equity Note Disclosure [Text Block]	Note 16 - Stockholders’ Equity and Regulatory Requirements Banks and bank holding companies are subject to regulatory capital requirements administered by federal banking agencies. Capital adequacy guidelines and, additionally for banks, prompt corrective action regulations, involve quantitative measures of assets, liabilities, and certain off-balance-sheet items calculated under regulatory accounting practices. Capital amounts and classifications are also subject to qualitative judgments by regulators. Failure to meet capital requirements can initiate regulatory action. The final rules implementing the Basel Committee on Banking Supervisions’ capital guidelines for U.S. banks (Basel III rules) became effective for the Company on January 1, 2015 with full compliance with all of the requirements being phased in over a multi-year schedule, and fully phased in by January 1, 2019. The net unrealized gain or loss on available for sale securities is not included in computing regulatory capital. Management believes as of December 31, 2017, the Bank and the Parent Corporation meet all capital adequacy requirements to which they are subject. Prompt corrective action regulations provide five classifications: well capitalized, adequately capitalized, undercapitalized, significantly undercapitalized and critically undercapitalized, although these terms are not used to represent overall financial condition. If adequately capitalized, regulatory approval is required to accept brokered deposits. If undercapitalized, capital distributions are limited, as is growth and expansion, and capital restoration plans are required. As of December 31, 2017 and 2016, the most recent regulatory notifications categorized the Bank as well capitalized under the regulatory framework for prompt corrective action. There are no conditions or events since that notification that management believes have changed the institution’s category. The following is a summary of the Bank’s and the Parent Corporation’s actual capital amounts and ratios as of December 31, 2017 and 2016, compared to the FRB and FDIC minimum capital adequacy requirements and the FDIC requirements for classification as a well-capitalized institution.

When fully phased in on January 1, 2019, each of the Company and the Bank will be required to maintain a 2.5% capital conservation buffer, above and beyond the capital levels otherwise required under applicable regulation. The implementation of this capital conservation buffer began on January 1, 2016 at a level of 0.625%, and will increase by 0.625% on each subsequent January 1 until it reaches 2.5% on January 1, 2019. Under this guidance banking institutions with a CET1, Tier 1 Capital Ratio and Total Risk Based Capital Ratio above the minimum regulatory adequate capital ratios but below the capital conservation buffer will face constraints on their ability to pay dividends, repurchase equity and pay discretionary bonuses to executive officers, based on the amount of the shortfall. As of December 31, 2017 both the Company and Bank satisfy the capital conservation buffer requirements applicable to them. The lowest ratio at the Company is the Total Risk Based Capital Ratio which was 1.79% above the minimum buffer ratio and, at the Bank, the lowest ratio was the Total Risk Based Capital Ratio which was 1.65% above the minimum buffer ratio.

Pension and Other Benefits Disclosure [Text Block]	Note 18 - Pension and Other Benefits Defined Benefit Plans The Company maintains a frozen noncontributory pension plan covering employees of the Company prior to the Merger. The benefits are based on years of service and the employee’s compensation over the prior five-year period. The plan’s benefits are payable in the form of a ten year certain and life annuity. The plan is intended to be a tax-qualified defined benefit plan under Section 401(a) of the Internal Revenue Code. Payments may be made under the Pension Plan once attaining the normal retirement age of 65 and are generally equal to 44% of a participant’s highest average compensation over a 5-year period. The following table sets forth changes in projected benefit obligation, changes in fair value of plan assets, funded status, and amounts recognized in the consolidated statements of condition for the Company’s pension plans at December 31, 2017 and 2016. 2017 2016 (dollars in thousands) Change in Benefit Obligation: Projected benefit obligation at January 1, $ 12,682 $ 13,068 Interest cost 478 514 Actuarial (gain) loss 642 216 Benefits paid - - Settlements (910) (1,116) Projected benefit obligation at December 31, $ 12,892 $ 12,682 Change in Plan Assets: Fair value of plan assets at January 1, $ 12,002 $ 10,287 Actual return on plan assets 1,517 831 Employer contributions - 2,000 Benefits paid - - Settlements (910) (1,116) Fair value of plan assets at December 31, $ 12,609 $ 12,002 Funded status $ (283) $ (680) The accumulated benefit obligation was $12.9 million and $12.7 million as of the year ended December 31, 2017 and 2016, respectively. Amounts recognized as a component of accumulated other comprehensive loss as of year-end that have not been recognized as a component of the net periodic pension expense for the plan are presented in the following table. The Company expects to recognize approximately $366,000 of the net actuarial loss reported in the following table as of December 31, 2017 as a component of net periodic pension expense during 2018. 2017 2016 (dollars in thousands) Net actuarial loss recognized in accumulated other comprehensive income $ 5,860 $ 6,272 The net periodic pension expense and other comprehensive income (before tax) for 2017, 2016 and 2015 includes the following: 2017 2016 2015 (dollars in thousands) Interest cost $ 478 $ 514 $ 519 Expected return on plan assets (640) (617) (562) Net amortization 412 407 433 Recognized settlement loss - - 650 Total net periodic pension expense $ 250 $ 304 $ 1,040 Total gain recognized in other comprehensive income (410) (405) (918) Total recognized in net periodic expense and other comprehensive income (before tax) $ (160) $ (101) $ 122 The following table presents the weighted average assumptions used to determine the pension benefit obligations at December 31, for the following three years. 2017 2016 2015 Discount rate 3.41 % 3.88 % 4.06 % Rate of compensation increase N/A N/A N/A The following table presents the weighted average assumptions used to determine net periodic pension cost for the following three years: 2017 2016 2015 (dollars in thousands) Discount rate 3.88 % 4.06 % 3.76 % Expected long-term return on plan assets 5.50 % 5.50 % 5.50 % Rate of compensation increase N/A N/A N/A The process of determining the overall expected long-term rate of return on plan assets begins with a review of appropriate investment data, including current yields on fixed income securities, historical investment data, historical plan performance and forecasts of inflation and future total returns for the various asset classes. This data forms the basis for the construction of a best-estimate range of real investment return for each asset class. An average, weighted real-return range is computed reflecting the plan’s expected asset mix, and that range, when combined with an expected inflation range, produces an overall best-estimate expected return range. Specific factors such as the plan’s investment policy, reinvestment risk and investment volatility are taken into consideration during the construction of the best estimate real return range, as well as in the selection of the final return assumption from within the range. Plan Assets The general investment policy of the Pension Trust is for the fund to experience growth in assets that will allow the market value to exceed the value of benefit obligations over time. The Company’s pension plan asset allocation as of December 31, 2017 and 2016, target allocation, and expected long-term rate of return by asset are as follows: Target Allocation % of Plan Assets – Year Ended 2017 % of Plan Assets – Year Ended 2016 Weighted Average Expected Long-Term Rate of Return Equity Securities Domestic 42% 41% 44% 3.2% International 10% 8% 8% 0.7% Debt and/or fixed income securities 46% 49% 47% 1.6% Cash and other alternative investments, including real estate funds, hedge funds and equity structured notes 2% 2% 1% 0% Total 100% $ 100% $ 100% $ 5.5% The fair values of the Company’s pension plan assets at December 31, 2017 and 2016, by asset class, are as follows: December 31, Fair Value Measurements at Reporting Date Using Asset Class Quoted Prices Significant Significant (dollars in thousands) Cash $ 175 $ 175 $ - $ - Equity securities: U.S. companies 5,175 5,175 - - International companies 1,056 1,056 - - Debt and/or fixed income securities 6,139 6,139 Real estate funds 64 64 - - Total $ 12,609 $ 12,609 $ - $ - December 31, Fair Value Measurements at Reporting Date Using Asset Class Quoted Prices Significant Significant (dollars in thousands) Cash $ 19 $ 19 $ - $ - Equity securities: U.S. companies 5,221 5,221 - - International companies 1,005 1,005 - - Debt and/or fixed income securities 5,689 5,689 Real estate funds 68 68 - - Total $ 12,002 $ 12,002 $ - $ - Fair Value of Plan Assets The Company used the following valuation methods and assumptions to estimate the fair value of assets held by the plan (for further information on fair value methods, see Note 22): Equity securities and real estate funds Debt and fixed income securities The investment manager is not authorized to purchase, acquire or otherwise hold certain types of market securities (subordinated bonds, real estate investment trusts, limited partnerships, naked puts, naked calls, stock index futures, oil, gas or mineral exploration ventures or unregistered securities) or to employ certain types of market techniques (margin purchases or short sales) or to mortgage, pledge, hypothecate, or in any manner transfer as security for indebtedness, any security owned or held by the Plan. Cash Flows Contributions The Bank expects to contribute $2,000,000 to its Pension Trust in 2018. Estimated Future Benefit Payments The following benefit payments, which reflect expected future service, as appropriate, for the following years are as follows (dollars in thousands): 2018 $ 719 2019 729 2020 728 2021 739 2022 728 2023-2027 3,559 401(k) Benefit Plan The Company maintains a 401(k) employee savings plan to provide for defined contributions which covers substantially all employees of the Company. Beginning with the 2013 Plan Year, the Plan was amended to provide for a 3% non-elective safe harbor contribution for all participants. For 2017, 2016 and 2015, employer contributions amounted to $383,000, $351,000 and $338,000, respectively.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Disclosure of Compensation Related Costs, Share-based Payments [Text Block]	Note 19 - Stock Based Compensation The Company’s stockholders approved the 2017 Equity Compensation Plan (“the Plan”) on May 23, 2017. The Plan eliminates all remaining issuable shares under previous plans and is the only outstanding plan as of December 31, 2017. The maximum number of shares of common stock or equivalents, which may be issued under the Plan, is 750,000. Grants under the Plan can be in the form of stock options (qualified or non-qualified), restricted shares, restricted share units or performance units. Shares available for grant and issuance under the Plan as of December 31, 2017 are 750,000. The Company intends to issue all shares under the Plan in the form of newly issued shares. Restricted stock and option awards typically have a three-year vesting period starting one year after the date of grant with one-third vesting each year. The options generally expire ten years from the date of grant. Restricted stock awards granted to new employees and board members may be granted with shorter vesting periods. Grants of performance units typically have a cliff vesting after three years or upon a change of control. All issuances are subject to forfeiture if the recipient leaves or is terminated prior to the awards vesting. Restricted shares have the same dividend and voting rights as common stock, while options and performance units do not. All awards are issued at fair value of the underlying shares at the grant date. The Company expenses the cost of the awards ratably over the vesting period. Forfeiture rates are not estimated but are handled on a case-by-case basis. No options were issued during the year ended December 31, 2017 or 2016. An aggregate of 57,164 restricted shares and 24,891 performance units were granted and awarded, respectively, during the year ended December 31, 2017 compared to 72,920 and 64,434 granted and awarded, respectively, for the year ended December 31, 2016. Option activity under the Company’s option plans as of and for the year ended December 31, 2017 were as follows: Shares Weighted- Weighted- Aggregate Outstanding at December 31, 2016 358,367 $ 6.26 Granted - - Exercised (66,389) 6.61 Forfeited/cancelled/expired - - Outstanding at December 31, 2017 291,978 $ 6.18 1.97 $ 5,714,355 Exercisable at December 31, 2017 288,446 $ 6.08 1.93 $ 5,673,725 The aggregate intrinsic value of outstanding and exercisable options above represents the total pre-tax intrinsic value (the difference between the Company’s closing stock price on December 31, 2017 and the exercise price, multiplied by the number of in-the-money options) that would have been received by the option holders had all option holders exercised their options on December 31, 2017. This amount changes based on the fair market value of the Parent Corporation’s stock.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments and Hedging Activities Disclosure [Text Block]	Note 21 – Derivatives The Company utilizes interest rate swap agreements as part of its asset liability management strategy to help manage its interest rate risk position. The notional amount of the interest rate swap does not represent amounts exchanged by the parties. The amount exchanged is determined by reference to the notional amount and the other terms of the individual interest rate swap agreements. Interest rate swaps were entered into on April 13, 2017, August 24, 2015, October 15, 2014 and December 30, 2014, each with a respective notional amount of $25.0 million and were designated as a cash flow hedge of a Federal Home Loan Bank advance. The swaps were determined to be fully effective during the period presented and therefore no amount of ineffectiveness has been included in net income. Therefore, the aggregate fair value of the swaps is recorded in other assets (liabilities) with changes in fair value 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 Company expects the hedges to remain fully effective during the remaining term of the swaps. Summary information about the interest rate swap designated as a cash flow hedges as of year-end is as follows (dollars in thousands): December 31, December 31, Notional amount $ 100,000 $ 75,000 Weighted average pay rates 1.66 % 1.59 % Weighted average receive rates 1.23 % 0.69 % Weighted average maturity 2.4 years 2.8 years Fair value $ 798 $ 88 Interest expense recorded on these swap transactions totaled approximately $406,200, $668,300, and $763,500 during 2017, 2016, and 2015 is reported as a component of interest expense on FHLB Advances.

Fair Value Measurements and Fai

Fair Value Measurements and Fair Value of Financial Instruments	12 Months Ended

Fair Value Disclosures [Abstract]
Fair Value Disclosures [Text Block]	Note 22 - Fair Value Measurements and Fair Value of Financial Instruments Fair value is the exchange price that would be received for an asset or paid to transfer a liability (exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. FASB ASC 820-10-05 defines fair value, establishes a framework for measuring fair value, establishes a three-level valuation hierarchy for disclosure of fair value measurements and enhances disclosure requirements for fair value measurements. The valuation hierarchy is based upon the transparency of inputs to the valuation of an asset or liability as of the measurement date. FASB ASC 820-10-65 provides additional guidance for estimating fair value in accordance with FASB ASC 820-10-05 when the volume and level of activity for the asset or liability have significantly decreased. This ASC also includes guidance on identifying circumstances that indicate a transaction is not orderly. FASB ASC 820-10-05 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 (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy under FASB ASC 820-10-05 are as follows: Level 1: Level 2: Level 3: 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. The following information should not be interpreted as an estimate of the fair value of the entire Company since a fair value calculation is only provided for a limited portion of the Company’s assets and liabilities. Due to a wide range of valuation techniques and the degree of subjectivity used in making the estimates, comparisons between the Company’s disclosures and those of other companies may not be meaningful. Assets and Liabilities Measured at Fair Value on a Recurring Basis The following methods and assumptions were used to estimate the fair values of the Company’s assets measured at fair value on a recurring basis at December 31, 2017 and December 31, 2016: Securities Available-for-Sale Where quoted prices are available in an active market, securities are classified within Level 1 of the valuation hierarchy. Level 1 inputs include securities that have quoted prices in active markets for identical assets. If quoted market prices are not available, then fair values are estimated by using pricing models, quoted prices of securities with similar characteristics, or discounted cash flows. Examples of instruments, which would generally be classified within Level 2 of the valuation hierarchy include municipal bonds and certain agency collateralized mortgage obligations. In certain cases where there is limited activity in the market for a particular instrument, assumptions must be made to determine the fair value of the instruments and these are classified as Level 3. When measuring fair value, the valuation techniques available under the market approach, income approach and/or cost approach are used. The Company’s evaluations are based on market data and the Company employs combinations of these approaches for its valuation methods depending on the asset class. Derivatives The fair value of derivatives are based on valuation models using observable market data as of the measurement date (level 2). Our derivatives are traded in an over-the-counter market where quoted market prices are not always available. Therefore, the fair values of derivatives are determined using quantitative models that utilize multiple market inputs. The inputs will vary based on the type of derivative, but could include interest rates, prices and indices to generate continuous yield or pricing curves, prepayment rate, and volatility factors to value the position. The majority of market inputs are actively quoted and can be validated through external sources, including brokers, market transactions and third-party pricing services. For financial assets and liabilities measured at fair value on a recurring basis, the fair value measurements by level within the fair value hierarchy used at December 31, 2017 and December 31, 2016 are as follows: December 31, 2017 Quoted Prices Significant Significant (dollars in thousands) Recurring fair value measurements: Assets Investment securities Available-for-sale: Federal agency obligations $ 56,022 $ - $ 56,022 $ - Residential mortgage pass-through securities 181,891 - 181,891 - Commercial mortgage pass-through securities 4,054 - 4,054 - Obligations of U.S. states and political subdivision 131,128 - 121,496 9,632 Trust preferred securities 4,671 - 4,671 - Corporate bonds and notes 29,693 - 29,693 - Asset-backed securities 12,050 - 12,050 - Certificates of deposit 625 - 625 - Equity securities 11,728 11,728 - - Other securities 3,422 3,422 - - Total available-for-sale 435,284 15,150 410,502 9,632 Derivatives 798 - 798 - Total assets $ 436,082 $ 15,150 $ 411,300 $ 9,632 December 31, 2016 Quoted Prices Significant Significant (dollars in thousands) Recurring fair value measurements: Assets Investment securities Available-for-sale: Federal agency obligations $ 52,837 $ - $ 52,837 $ - Residential mortgage pass-through securities 72,497 - 72,497 - Commercial mortgage pass-through securities 4,209 - 4,209 - Obligations of U.S. states and political subdivision 150,605 - 132,387 18,218 Trust preferred securities 5,666 - 5,666 - Corporate bonds and notes 36,928 - 36,928 - Asset-backed securities 14,583 - 14,583 - Certificates of deposit 983 - 983 - Equity securities 11,710 11,710 - - Other securities 3,272 3,272 - - Total available-for-sale 353,290 14,982 320,090 18,218 Derivatives 88 - 88 - Total assets $ 353,378 $ 14,982 $ 320,178 $ 18,218 There were no transfers between Level 1 and Level 2 during the years ended December 31, 2017 and 2016. Assets Measured at Fair Value on a Non-Recurring Basis The Company may be required periodically to measure certain assets at fair value on a non-recurring basis in accordance with GAAP. These adjustments to fair value usually result from the application of lower of cost or fair value accounting or impairment write-downs of individual assets. The following methods and assumptions were used to estimate the fair values of the Company’s assets measured at fair value on a non-recurring basis at December 31, 2017 and December 31, 2016: Loans Held-for-Sale Residential mortgage loans, originated and intended for sale in the secondary market, are carried at the lower of aggregate cost or estimated fair value as determined by outstanding commitments from investors. For these loans originated and intended for sale, gains and losses on loan sales (sale proceeds minus carrying value) are recorded in other income and direct loan origination costs and fees are deferred at origination of the loan and are recognized in other income upon sale of the loan. Management obtains quotes or bids on all or part of these loans directly from the purchasing financial institutions (Level 2). Other loans held-for-sale are carried at the lower of aggregate cost or estimated fair value. A portion of these loans, taxi medallion loans, have no material observable trading in any market. The approach to determining fair value involved several steps, including a detailed collateral analysis of the underlying medallions, performance projections for individual loans, discounted cash flow modeling and consideration of indicative bids, which at December 31, 2016 did not necessarily contemplate whole loan sales (Level 3). Impaired Loans The Company may record adjustments to the carrying value of loans based on fair value measurements, generally as partial charge-offs of the uncollectible portions of these loans. These adjustments also include certain impairment amounts for collateral dependent loans calculated in accordance with GAAP. Impairment amounts are generally based on the fair value of the underlying collateral supporting the loan and, as a result, the carrying value of the loan less the calculated impairment amount applicable to that loan does not necessarily represent the fair value of the loan. Real estate collateral is valued using independent appraisals or other indications of value based on recent comparable sales of similar properties or assumptions generally observable by market participants. However, due to the substantial judgment applied and limited volume of activity as compared to other assets, fair value is based on Level 3 inputs. Estimates of fair value used for collateral supporting commercial loans generally are based on assumptions not observable in the market place and are also based on Level 3 inputs. For assets measured at fair value on a non-recurring basis, the fair value measurements at December 31, 2017 and December 31, 2016 are as follows: Fair Value Measurements at Reporting Date Using Assets measured at fair value on a nonrecurring basis: December 31, Quoted Significant Significant Impaired loans: (dollars in thousands) Commercial real estate $ 1,094 $ - $ - $ 1,094 Fair Value Measurements at Reporting Date Using Assets measured at fair value on a nonrecurring basis: December 31, Quoted Significant Significant Impaired loans: (dollars in thousands) Commercial real estate $ 1,099 $ - $ - $ 1,099 Loans held-for-sale: Commercial 70,105 - 4,509 65,596 Commercial real estate 7,712 - 7,712 - Impaired Loans - Assets Measured With Significant Unobservable Level 3 Inputs Recurring basis The tables below present a reconciliation of all assets measured at fair value on a recurring basis using significant unobservable inputs (Level 3) for the year ended December 31, 2017 and year ended December 31, 2016: Municipal (dollars in thousands) Beginning balance, January 1, 2017 $ 18,218 Principal paydowns (8,586) Ending balance, December 31, 2017 $ 9,632 Municipal (dollars in thousands) Beginning balance, January 1, 2016 $ - Other (1) 18,335 Principal paydowns (117) Ending balance, December 31, 2016 $ 18,218 (1) Includes transfers from held-to-maturity to available-for-sale designation The following methods and assumptions were used to estimate the fair values of the Company’s assets measured at fair value on a recurring basis at December 31, 2017 and December 31, 2016.

For the Company, as for most financial institutions, the majority of its assets and liabilities are considered financial instruments as defined in FASB ASC 825-10. Many of the Company’s financial instruments, however, lack an available trading market as characterized by a willing buyer and willing seller engaging in an exchange transaction. It is also the Company’s general practice and intent to hold its financial instruments to maturity and not to engage in trading or sales activities except for loans held-for-sale and investment securities available-for-sale.

For fixed-rate loan commitments, fair value also considers the difference between current levels of interest rates and the committed rates. The fair values of letters of credit and lines of credit are based on fees currently charged for similar agreements or on the estimated cost to terminate or otherwise settle the obligations with the counterparties at the reporting date. The fair value of commitments to originate loans is immaterial and not included in the tables above. Changes in assumptions or estimation methodologies may have a material effect on these estimated fair values. The Company’s remaining assets and liabilities, which are not considered financial instruments, have not been valued differently than has been customary with historical cost accounting. No disclosure of the relationship value of the Company’s core deposit base is required by FASB ASC 825-10. Fair value estimates are based on existing balance sheet financial instruments, without attempting to estimate the value of anticipated future business and the value of assets and liabilities that are not considered financial instruments. For example, there are certain significant assets and liabilities that are not considered financial assets or liabilities, such as the brokerage network, deferred taxes, premises and equipment, and goodwill. In addition, the tax ramifications related to the realization of the unrealized gains and losses can have a significant effect on fair value estimates and have not been considered in the estimates. Management believes that reasonable comparability between financial institutions may not be likely, due to the wide range of permitted valuation techniques and numerous estimates which must be made, given the absence of active secondary markets for many of the financial instruments. This lack of uniform valuation methodologies also introduces a greater degree of subjectivity to these estimated fair values.

Income taxes for the fourth quarter of 2017 had a notable increase that was mainly attributable to a charge against the Company’s deferred tax assets of $5.6 million due to the impact of Tax Cuts and Jobs Act of 2017. The provision for loan losses for the fourth quarter 2016 was a notable increase that was mainly attributable to the transfer of the Company’s taxi medallion portfolio to loans held-for-sale.

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2017
Accounting Policies [Abstract]
Business Policy [Policy Text Block]	Business ConnectOne Bancorp, Inc. (the “Parent Corporation”) is incorporated under the laws of the State of New Jersey and is a registered bank holding company. The Parent Corporation’s business currently consists of the operation of its wholly-owned subsidiary, ConnectOne Bank (the “Bank” and, collectively with the Parent Corporation and the Parent Corporation’s subsidiaries, the “Company”). The Bank’s subsidiaries include Union Investment Co. (a New Jersey investment company), Twin Bridge Investment Co. (a Delaware investment company), ConnectOne Preferred Funding Corp. (a New Jersey real estate investment trust), Center Financial Group, LLC (a New Jersey financial services company), Center Advertising, Inc. (a New Jersey advertising company), Morris Property Company, LLC, (a New Jersey limited liability company), Volosin Holdings, LLC, (a New Jersey limited liability company), and NJCB Spec-1, LLC (a New Jersey limited liability company). The Bank is a community-based, full-service New Jersey-chartered commercial bank that was founded in 2005. The Bank operates from its headquarters located at 301 Sylvan Avenue in the Borough of Englewood Cliffs, Bergen County, New Jersey and through its twenty other banking offices. Substantially all loans are secured with various types of collateral, including business assets, consumer assets and commercial/residential real estate. Each borrower’s ability to repay its loans is dependent on the conversion of assets, cash flows generated from the borrowers’ business, real estate rental and consumer wages.
Basis of Financial Statement Presentation, Policy [Policy Text Block]	Basis of Financial Statement Presentation The consolidated financial statements of the Parent Corporation are prepared on an accrual basis and include the accounts of the Parent Corporation and the Company. All significant intercompany accounts and transactions have been eliminated from the accompanying consolidated financial statements. The consolidated financial statements have been prepared in conformity with U.S. generally accepted accounting principles.
Segment Policy [Policy Text Block]	Segments FASB ASC 28, “Segment Reporting,” requires companies to report certain information about operating segments. The Company is managed as one segment: a community bank. All decisions including but not limited to loan growth, deposit funding, interest rate risk, credit risk and pricing are determined after assessing the effect on the totality of the organization. For example, loan growth is dependent on the ability of the organization to fund this growth through deposits or other borrowings. As a result, the Company is managed as one operating segment.
Use of Estimates, Policy [Policy Text Block]	Use of Estimates In preparing the consolidated financial statements, management has made estimates and assumptions that affect the reported amounts of assets and liabilities as of the dates of the consolidated statements of condition and that affect the results of operations for the periods presented. Actual results could differ significantly from those estimates.
Cash and Cash Equivalents, Policy [Policy Text Block]	Cash and Cash Equivalents Cash and cash equivalents include cash, deposits with other financial institutions with maturities of less than 90 days, and federal funds sold. Net cash flows are reported for customer loan and deposit transactions, interest-bearing deposits in other financial institutions, and federal funds purchased and repurchase agreements.
Investment Securities, Policy [Policy Text Block]	Investment Securities The Company accounts for its investment securities in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 320-10-05. Investments are classified into the following categories: (1) held-to-maturity securities, for which the Company has both the positive intent and ability to hold until maturity, which are reported at amortized cost; (2) trading securities, which are purchased and held principally for the purpose of selling in the near term and are reported at fair value with unrealized gains and losses included in earnings; and (3) available-for-sale securities, which do not meet the criteria of the other two categories and which management believes may be sold prior to maturity due to changes in interest rates, prepayment risk, liquidity or other factors, and are reported at fair value, with unrealized gains and losses, net of applicable income taxes, reported as a component of accumulated other comprehensive income, which is included in stockholders’ equity and excluded from earnings. Investment securities are adjusted for amortization of premiums and accretion of discounts as adjustments to interest income, which are recognized on a level yield method without anticipating prepayments, except for mortgage backed securities where prepayments are anticipated. Investment securities gains or losses are determined using the specific identification method. Securities are evaluated on at least a quarterly basis, and more frequently when market conditions warrant such an evaluation, to determine whether a decline in their value is other-than-temporary. FASB ASC 320-10-65 clarifies the interaction of the factors that should be considered when determining whether a debt security is other-than-temporarily impaired. For debt securities, management must assess whether (a) it has the intent to sell the security and (b) it is more likely than not that it will be required to sell the security prior to its anticipated recovery. These steps are done before assessing whether the entity will recover the cost basis of the investment. In instances when a determination is made that an other-than-temporary impairment exists but the investor does not intend to sell the debt security and it is not more likely than not that it will be required to sell the debt security prior to its anticipated recovery, FASB ASC 320-10-65 changed the presentation and amount of the other-than-temporary impairment recognized in the Consolidated Statement of Income. The other-than-temporary impairment is separated into (a) the amount of the total other-than-temporary impairment related to a decrease in cash flows expected to be collected from the debt security (the credit loss) and (b) the amount of the total other-than-temporary impairment related to all other factors. The amount of the total other-than-temporary impairment related to the credit loss is recognized through earnings. The amount of the total other-than-temporary impairment related to all other factors is recognized through other comprehensive income.
Loan, Held-for-sale, Policy [Policy Text Block]	Loans Held-for-Sale Residential mortgage loans, originated and intended for sale in the secondary market, are carried at the lower of aggregate cost or estimated fair value as determined by outstanding commitments from investors. For these loans originated and intended for sale, gains and losses on loan sales (sale proceeds minus carrying value) are recorded in other income and direct loan origination costs and fees are deferred at origination of the loan and are recognized in other income upon sale of the loan. Other loans held-for-sale are carried at the lower of aggregate cost or estimated fair value. Fair value on these loans is determined based on the terms of the loan, such as interest rate, maturity date, reset term, as well as sales of similar assets.
Loans Policy [Policy Text Block]	Loans Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are reported at the principal balance outstanding, net of deferred loan fees and costs, and an allowance for loan losses. Interest income is accrued on the unpaid principal balance. Loan origination fees, net of certain direct origination costs, are deferred and recognized in interest income using the level-yield method without anticipating prepayments. Loan segments are defined as a group of loans, which share similar initial measurement attributes, risk characteristics, and methods for monitoring and assessing credit risk. Management has determined that the Company has five segments of loans: commercial, commercial real estate, commercial construction, residential real estate (including home equity) and consumer. Loans that are 90 days past due are placed on nonaccrual and previously accrued interest is reversed and charged against interest income unless the loans is both well-secured and in the process of collection. Past due status is based on the contractual terms of the loan. In all cases, loans are placed on nonaccrual or charged-off at an earlier date if collection of principal or interest is considered doubtful. Nonaccrual loans and loans 90 days or greater past due and still accruing include both smaller balance homogeneous loans that are collectively evaluated for impairment and loans individually evaluated for impairment. All interest accrued but not received for loans placed on nonaccrual are reversed against interest income. Interest received on such loans is accounted for on the cash-basis or cost-recovery method, until qualifying for return to accrual. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured. The policy of the Company is to generally grant commercial, residential and consumer loans to residents and businesses within its New Jersey and New York market area. The borrowers’ abilities to repay their obligations are dependent upon various factors including the borrowers’ income and net worth, cash flows generated by the borrowers’ underlying collateral, value of the underlying collateral, and priority of the lender’s lien on the property. Such factors are dependent upon various economic conditions and individual circumstances beyond the control of the Company. The Company is therefore subject to risk of loss. The Company believes its lending policies and procedures adequately minimize the potential exposure to such risks and that adequate provisions for loan losses are provided for all known and inherent risks. Collateral and/or personal guarantees are required for a large majority of the Company’s loans.
Allowance for Loan and Lease Loss Policy [Policy Text Block]	Allowance for Loan Losses The allowance for loan losses is a valuation allowance for probable incurred credit losses. Loan losses are charged against the allowance when management believes the uncollectibility of a loan balance is confirmed. Subsequent recoveries, if any, are credited to the allowance. Management estimates the allowance balance required using past loan loss experience, the nature and volume of the portfolio, information about specific borrower situations and estimated collateral values, economic conditions, and other factors. Allocations of the allowance may be made for specific loans, but the entire allowance is available for any loan that, in management’s judgment, should be charged off. The allowance consists of specific and general components. The specific component relates to loans that are individually classified as impaired. A loan is considered impaired when, based on current information and events, it is probable that the Bank will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement. Factors considered by management in determining impairment include payment status and the probability of collecting scheduled principal and interest payments when due. Loans for which the terms have been modified as a concession to the borrower due to the borrower experiencing financial difficulties are considered troubled debt restructurings (“TDR”) and are classified as impaired. The impairment of a loan can be measured at (1) the fair value of the collateral less costs to sell, if the loan is collateral dependent, (2) at the value of expected future cash flows using the loan’s effective interest rate, or (3) at the loan’s observable market price. Generally, the Bank measures impairment of such loans by reference to the fair value of the collateral less costs to sell. Loans that experience minor payment delays and payment shortfall generally are not classified as impaired. Loans $250,000 and over are individually evaluated for impairment. If a loan that is identified as impaired and the individual test results in an impairment, a portion of the allowance is allocated so that the loan is reported, net, at the fair value of collateral less costs to sell if repayment is expected solely from the collateral or at the present value of estimated future cash flows using the loan’s existing rate if the loan is dependent on cash flow. Loans with balances less than $250,000 are collectively evaluated for impairment, and accordingly, are not separately identified for impairment disclosures. Factors considered by management in determining impairment include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record, and the amount of the shortfall in relation to the principal and interest owed. Troubled debt restructurings are separately identified for impairment disclosures and are measured at the present value of estimated future cash flows using the loan’s effective rate at inception. If a troubled debt restructuring is considered to be a collateral dependent loan, the loan is reported, net, at the fair value of the collateral. For troubled debt restructurings that subsequently default, the Company determines the amount of reserve in accordance with the accounting policy for the allowance for loan losses. The general component covers non-impaired loans and is based on historical loss experience adjusted for current factors. The historical loss experience, the primary factor, is determined by loan segment and is based on the actual loss history experienced by the Bank over an actual three year rolling calculation. This actual loss experience is supplemented with other economic factors based on the risks present for each portfolio segment. This actual loss experience is supplemented with the exogenous factor adjustments based on the risks present for each loan category. These exogenous factors (nine total) include consideration of the following: concentrations of credit; delinquency & nonaccrual trends; economic & business conditions including evaluation of the national and regional economies and industries with significant loan concentrations; external factors including legal, regulatory or competitive pressures that may impact the loan portfolio; changes in the experience, ability, or size of the lending staff, management, or board of directors that may impact the loan portfolio; changes in underwriting standards, collection procedures, charge-off practices, or other changes in lending policies and procedures that may impact the loan portfolio; loss and recovery trends; changes in portfolio size and mix; and trends in problem loans.
Purchased Credit-Impaired Loans , Policy [Policy Text Block]	Purchased Credit-Impaired Loans The Company acquires groups of loans in conjunction with mergers, some of which have shown evidence of credit deterioration since origination. These purchased credit-impaired loans are recorded at their estimated fair value, such that there is no carryover of the seller’s allowance for loan losses. After acquisition, losses are recognized by an increase in the allowance for loan losses. Such purchased credit-impaired loans (“PCI”) are identified on an individual basis. The Company estimates the amount and timing of expected cash flows for each loan and the expected cash flows in excess of amount paid is recorded as interest income over the remaining life of the loan (accretable yield). The excess of the loan’s contractual principal and interest over expected cash flows is not recorded (nonaccretable difference). A PCI loan may be resolved either through a sale of the loan, by working with the customer and obtaining partial or full repayment, by short sale of the collateral, or by foreclosure. A gain or loss on resolution would be recognized based on the difference between the proceeds received and the carrying amount of the loan. PCI loans that met the criteria for nonaccrual may be considered performing, regardless of whether the customer is contractually delinquent, if management can reasonably estimate the timing and amount of the expected cash flows on such loans and if management expects to fully collect the new carrying value of the loans. As such, management may no longer consider the loans to be nonaccrual or nonperforming and may accrue interest on these loans, including the impact of any accretable discount.
Derivatives, Policy [Policy Text Block]	Derivatives The Company records cash flow hedges at the inception of the derivative contract based on the Company’s intentions and belief as to likely effectiveness as a hedge. Cash flow hedges represent a hedge of a forecasted transaction or the variability of cash flows to be received or paid related to a recognized asset or liability. For a cash flow hedge, the gain or loss on the derivative is reported in other comprehensive income and is reclassified into earnings in the same periods during which the hedged transaction affects earnings. The changes in the fair value of derivatives that are not highly effective in hedging the changes in fair value or expected cash flows of the hedged item are recognized immediately in current earnings. Changes in the fair value of derivatives that do not qualify for hedge accounting are reported currently in earnings, as noninterest income. Net cash settlements on derivatives that qualify for hedge accounting are recorded in interest income or interest expense, based on the item being hedged. Net cash settlements on derivatives that do not qualify for hedge accounting are reported in noninterest income. Cash flows on hedges are classified in the cash flow statement the same as the cash flows of the items being hedged. The Company formally documents the relationship between derivatives and hedged items, as well as the risk-management objective and the strategy for undertaking hedge transactions at the inception of the hedging relationship. This documentation includes linking cash flow hedges to specific assets and liabilities on the balance sheet or to specific firm commitments or forecasted transactions. The Company also formally assesses, both at the hedge’s inception and on an ongoing basis, whether the derivative instruments that are used are highly effective in offsetting changes in fair values or cash flows of the hedged items. The Company discontinues hedge accounting when it determines that the derivative is no longer effective in offsetting changes in the fair value or cash flows of the hedged item, the derivative is settled or terminates, a hedged forecasted transaction is no longer probable, a hedged firm commitment is no longer firm, or treatment of the derivative as a hedge is no longer appropriate or intended. When hedge accounting is discontinued, subsequent changes in fair value of the derivative are recorded as noninterest income. When a cash flow hedge is discontinued but the hedged cash flows or forecasted transactions are still expected to occur, gains or losses that were accumulated in other comprehensive income are amortized into earnings over the same periods which the hedged transactions will affect earnings.
Restricted Stock [Policy Text Block]	Restricted Stock The Bank is a member of the Federal Home Loan Bank (“FHLB”) of New York. Members are required to own a certain amount of stock based on the level of borrowings and other factors, and may invest in additional amounts. FHLB stock is carried at cost, classified as a restricted security, and periodically evaluated for impairment based on ultimate recovery of par value. Cash dividends on the stock are reported as income.
Transfers of Financial Assets, Policy [Policy Text Block]	Transfers of Financial Assets Transfers of financial assets are accounted for as sales, when control over the assets has been relinquished. Control over transferred assets is deemed to be surrendered when the assets have been isolated from the Company, 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 the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity.
Premises and Equipment	Premises and Equipment Land is carried at cost and premises and equipment are stated at cost less accumulated depreciation. Buildings and related components are depreciated using the straight-line method with useful lives ranging from 4 to 39 years. Furniture, fixtures and equipment are depreciated using the straight-line (or accelerated) method with useful lives ranging from 3 to 10 years.
Other Real Estate Owned Policy [Policy Text Block]	Other Real Estate Owned Other real estate owned (“OREO”), representing property acquired through foreclosure and held-for-sale, is initially recorded at fair value less cost to sell at the date of foreclosure, establishing a new cost basis. Subsequently, valuations are periodically performed by management and the assets are carried at the lower of carrying amount or fair value less cost to sell. Costs relating to holding the assets are charged to expenses.
Employee Benefit Plans, Policy [Policy Text Block]	Employee Benefit Plans The Company has a noncontributory pension plan that covered all eligible employees up until September 30, 2007, at which time the Company froze its defined benefit pension plan. As such, all future benefit accruals in this pension plan were discontinued and all retirement benefits that employees would have earned as of September 30, 2007 were preserved. The Company’s policy is to fund at least the minimum contribution required by the Employee Retirement Income Security Act of 1974. The costs associated with the plan are accrued based on actuarial assumptions and included in salaries and employee benefits expense. The Company accounts for its defined benefit pension plan in accordance with FASB ASC 715-30. FASB ASC 715-30 requires that the funded status of defined benefit postretirement plans be recognized on the Company’s statement of financial condition and changes in the funded status be reflected in other comprehensive income. FASB ASC 715-30 also requires companies to measure the funded status of the plan as of the date of its fiscal year-end. The Company maintains a 401(k) employee savings plan to provide for defined contributions which covers substantially all employees of the Company. Employee 401(k) and profit sharing plan expense is the amount of matching contributions.
Stock-Based Compensation Policy [Policy Text Block]	Stock-Based Compensation Stock compensation accounting guidance (FASB ASC 718, “Compensation-Stock Compensation”) requires that the compensation cost related to share-based payment transactions be recognized in financial statements. That cost will be measured based on the grant date fair value of the equity or liability instruments issued. The stock compensation accounting guidance covers a wide range of share-based compensation arrangements including stock options, restricted share plans, performance-based awards, share appreciation rights and employee share purchase plans. Stock compensation accounting guidance requires that compensation cost for all stock awards be calculated and recognized over the employees’ service period, generally defined as the vesting period. For awards with graded-vesting, compensation cost is recognized on a straight-line basis over the requisite service period for the entire award. A Black-Scholes model is used to estimate the fair value of stock options while the market price of the Company’s common stock at the date of grant is used for restricted stock awards. See Note 19 of the Notes to Consolidated Financial Statements for a further discussion.
Treasury Stock Policy [Policy Text Block]	Treasury Stock Subject to limitations applicable to the Parent Corporation, treasury stock purchases may be made from time to time as, in the opinion of management, market conditions warrant, in the open market or in privately negotiated transactions. Shares repurchased are added to the corporate treasury and will be used for future stock dividends and other issuances. The repurchased shares are recorded as treasury stock, which results in a decrease in stockholders’ equity. Treasury stock is recorded using the cost method and accordingly is presented as a reduction of stockholders’ equity. During the years ended December 31, 2017, 2016 and 2015, the Parent Corporation did not purchase any of its shares.
Goodwill, Policy [Policy Text Block]	Goodwill Goodwill arises from business combinations and is generally determined as of the excess of the fair value of the consideration transferred, plus the fair value of any noncontrolling interests in the acquiree, over the fair value of the net assets acquired and liabilities assumed as of the acquisition date. Goodwill and intangible assets acquired in a purchase business combination and determined to have an indefinite useful life are not amortized, but tested for impairment annually or more frequently if events and circumstances exists that indicate that a goodwill impairment test should be performed. The Company has selected December 31, as the date to perform the annual impairment test. No impairment charge was deemed necessary for the years ended December 31, 2017, 2016 and 2015.
Other Intangible Assets, Policy [Policy Text Block]	Other Intangible Assets Other intangible assets consist of core deposits arising from business combinations that are amortized over their estimated useful lives to their estimated residual value.
Comprehensive Income, Policy [Policy Text Block]	Comprehensive Income Total comprehensive income includes all changes in equity during a period from transactions and other events and circumstances from nonowner sources. The Company’s other comprehensive income is comprised of unrealized holding gains and losses on securities available-for-sale, unrecognized actuarial gains and losses of the Company’s defined benefit pension plan and unrealized gains and losses on cash flow hedges, net of taxes.
Restrictions on Cash [Policy Text Block]	Restrictions on Cash Cash on hand or on deposit with the Federal Reserve Bank is required to meet regulatory reserve and clearing requirements.
Dividend Restriction, Policy [Policy Text Block]	Dividend Restriction Banking regulations require maintaining certain capital levels and may limit the dividends paid by the Bank to the Parent Corporation or by the Parent Corporation to the stockholders.
Fair Value of Financial Instruments, Policy [Policy Text Block]	Fair Value of Financial Instruments Fair values of financial instruments are estimated using relevant market information and other assumptions, as more fully disclosed in a separate note. Fair value estimates involve uncertainties and matters of significant judgment regarding interest rates, credit risk, prepayments, and other factors, especially in the absence of broad markets for particular items. Changes in assumptions or in market conditions could significantly affect the estimates.
Bank-Owned Life Insurance, Policy [Policy Text Block]	Bank Owned Life Insurance The Company invests in Bank Owned Life Insurance (“BOLI”) to help offset the cost of employee benefits. The change in the cash surrender value of the BOLI is recorded as a component of noninterest income.
Income Tax, Policy [Policy Text Block]	Income Taxes Income tax expense is the total of the current year income tax due or refundable and the change in deferred tax assets and liabilities. Deferred tax assets and liabilities are the expected future tax amounts for the temporary differences between carrying amounts and tax bases of assets and liabilities, computed using enacted tax rates. A valuation allowance, if needed, reduces deferred tax assets to the amount expected to be realized. A tax position is recognized as a benefit only if it is “more likely than not” that the tax position would be sustained in a tax examination, with a tax examination being presumed to occur. 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.
Advertising Costs, Policy [Policy Text Block]	Advertising Costs The Company recognizes its marketing and advertising cost as incurred.
Reclassification, Policy [Policy Text Block]	Reclassifications Certain reclassifications have been made in the consolidated financial statements and footnotes for 2016 and 2015 to conform to the classifications presented in 2017. Such reclassifications had no impact on net income or stockholders’ equity.

General Discussion of Pension and Other Postretirement Benefits		The Company maintains a frozen noncontributory pension plan covering employees of the Company prior to the Merger. The benefits are based on years of service and the employee's compensation over the prior five-year period. The plan's benefits are payable in the form of a ten year certain and life annuity. The plan is intended to be a tax-qualified defined benefit plan under Section 401(a) of the Internal Revenue Code. Payments may be made under the Pension Plan once attaining the normal retirement age of 65 and are generally equal to 44% of a participant's highest average compensation over a 5-year period.
