Disclosure Text Block [Abstract]
Organization, Consolidation and Presentation of Financial Statements Disclosure [Text Block]	Note 1. Nature of Operations and Principles of Consolidation The consolidated financial statements of ConnectOne Bancorp, Inc. (the “Parent Corporation”) are prepared on an accrual basis and include the accounts of the Parent Corporation and its wholly-owned subsidiary, ConnectOne Bank (the “Bank” and, collectively with the Parent Corporation and the Parent Corporation’s other direct and indirect subsidiaries, the “Company”). All significant intercompany accounts and transactions have been eliminated from the accompanying consolidated financial statements. 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-one other banking offices. Substantially all loans are secured by specific items of collateral including business assets, consumer assets, and commercial and residential real estate. Commercial loans are expected to be repaid from cash flow from business operations. There are no significant concentrations of loans to any one industry or client. However, the clients’ ability to repay their loans is dependent on the cash flows, real estate and general economic conditions in the area. The following unaudited consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X, and, accordingly, do not include all of the information and footnotes required by U.S. generally accepted accounting principles for complete financial statements. However, in the opinion of management, all adjustments (consisting only of normal recurring accruals) considered necessary for a fair presentation have been included. Operating results for the three months ended September 30, 2015 are not necessarily indicative of the results that may be expected for the full year ending December 31, 2015, or for any other interim period. The Company’s 2014 Annual Report on Form 10-K, should be read in conjunction with these financial statements. 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. The consolidated financial statements have been prepared in conformity with U.S. generally accepted accounting principles (“U.S. GAAP”). Some items in the prior year financial statements were reclassified to conform to current presentation. Reclassifications had no effect on prior year net income or stockholders’ equity.

Accounting Changes and Error Corrections [Text Block]	Note 2. New Authoritative Accounting Guidance ASU No. 2015-03, “Interest—Imputation of Interest (Subtopic 835-30) Simplifying the Presentation of Debt Issuance Costs” requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The recognition and measurement guidance for debt issuance costs are not affected by the amendments in the ASU No. 2015-03. ASU No. 2015-03 will be effective for reporting periods (including interim periods) beginning after December 15, 2015. ASU No. 2015-03 became effective for the Company on January 1, 2015 and did not have a significant impact on its consolidated financial statements.

Business Combinations [Abstract]
Business Combination Disclosure [Text Block]	Note 3. Business Combinations On January 20, 2014, the Parent Corporation entered into an Agreement and Plan of Merger (the “Merger Agreement”) with ConnectOne Bancorp, Inc., a New Jersey Company (“Legacy ConnectOne”). Effective July 1, 2014 (the “Effective Time”), the Parent Corporation completed the merger contemplated by the Merger Agreement (the “Merger”) with Legacy ConnectOne. At closing, Legacy ConnectOne merged with and into the Parent Corporation, with the Parent Corporation as the surviving Company. Also at closing, the Parent Corporation changed its name from “Center Bancorp, Inc.” to “ConnectOne Bancorp, Inc.” and changed its NASDAQ trading symbol to “CNOB” from “CNBC.” Pursuant to the Merger Agreement, holders of Legacy ConnectOne common stock, no par value per share (the “Legacy ConnectOne Common Stock”), received 2.6 shares of common stock of the Parent Corporation, no par value per share (the “Company Common Stock”), for each share of Legacy ConnectOne Common Stock held immediately prior to the effective time of the Merger, with cash to be paid in lieu of fractional shares. Each outstanding share of Company Common Stock remained outstanding and was unaffected by the Merger. Each option granted by Legacy ConnectOne to purchase shares of Legacy ConnectOne Common Stock was converted into an option to purchase Company Common Stock on the same terms and conditions as were applicable prior to the Merger (taking into account any acceleration or vesting by reason of the consummation of the Merger and its related transactions), subject to adjustment of the exercise price and the number of shares of Company Common Stock issuable upon exercise of such option based on the 2.6 exchange ratio. Immediately following the Merger, Union Center National Bank, a bank organized pursuant to the laws of the United States, and a wholly owned subsidiary of the Parent Corporation (“UNCB”), merged (the “Bank Merger”) with and into ConnectOne Bank, a New Jersey state-chartered commercial bank and a wholly owned subsidiary of Legacy ConnectOne, with ConnectOne Bank as the surviving entity (the “Bank”). The Bank now conducts business only in the name of and under the brand of ConnectOne. The assets acquired and liabilities assumed have been accounted for under the acquisition method of accounting. The assets and liabilities, both tangible and intangible, were recorded at their fair values as of July 1, 2014 based on management’s best estimate using the information available as of the Merger date. The application of the acquisition method of accounting resulted in the recognition of goodwill of $129,105,000 and a core deposit intangible of $5,308,000. As of July 1, 2014, Legacy ConnectOne had assets with a carrying value of approximately $1.5 billion, including loans with a carrying value of approximately $1.2 billion, and deposits with a carrying value of approximately $1.1 billion. The table below summarizes the amounts recognized as of the Merger date for each major class of assets acquired and liabilities assumed, the estimated fair value adjustments and the amounts recorded in the Company’s financial statements at fair value at the Merger date (in thousands): Consideration paid through Parent Corporation common stock issued to Legacy ConnectOne shareholders and fair value of stock options acceleration was: $ 264,231 Legacy Fair value As recorded Cash and cash equivalents $ 70,318 $ — $ 70,318 Investment securities 28,436 16 (a) 28,452 Restricted stock 13,646 — 13,646 Loans held for sale 190 — 190 Loans 1,304,600 (5,316 ) (b) 1,299,284 Bank owned life insurance 15,481 — 15,481 Premises and equipment 7,380 (905) (c) 6,475 Accrued interest receivable 4,470 — 4,470 Core deposit and other intangibles — 5,308 (d) 5,308 Other real estate owned 2,455 — 2,455 Other assets 10,636 3,650 (e) 14,286 Deposits (1,049,666 ) (1,676 ) (f) (1,051,342 ) FHLB borrowings (262,046 ) (1,324 ) (g) (263,370 ) Other liabilities (10,527 ) — (10,527 ) Total identifiable net assets $ 135,373 $ (247 ) $ 135,126 Goodwill recorded in the Merger $ 129,105 The following provides an explanation of certain fair value adjustments presented in the above table: a) Represents the fair value adjustment on investment securities held to maturity. b) Represents the elimination of Legacy ConnectOne’s allowance for loan and lease losses, deferred fees, deferred costs and an adjustment of the amortized cost of loans to estimated fair value, which includes an interest rate mark and credit mark. c) Represent an adjustment to reflect the fair value of above-market rent on leased premises. The above-market rent adjustment will be amortized on a straight-line basis over the remaining term of the respective leases. d) Represents intangible assets recorded to reflect the fair value of core deposits. The core deposit asset was recorded as an identifiable intangible asset and will be amortized on an accelerated basis over the estimated average life of the deposit base. e) Consist primarily of adjustments in net deferred tax assets resulting from the fair value adjustments related to acquired assets, liabilities assumed and identifiable intangibles recorded. f) Represents fair value adjustment on time deposits as the weighted average interest rates of time deposits assumed exceeded the costs of similar funding available in the market at the time of the Merger, as well as the elimination of fees paid on brokered time deposits. g) Represents the fair value adjustment on FHLB borrowings as the weighted average interest rate of FHLB borrowings assumed exceeded the cost of similar funding available in the market at the time of the Merger. The amount of goodwill recorded represents the excess purchase price over the estimated fair value of the net assets acquired by the Company and reflects the economies of scale, increased market share and lending capabilities, greater access to best-in-class banking technology, and related synergies that are expected to result from the acquisition. Except for collateral dependent loans with deteriorated credit quality, the fair values for loans acquired from Legacy ConnectOne were estimated using cash flow projections based on the remaining maturity and repricing terms. Cash flows were adjusted by estimated future credit losses and the rate of prepayments. Projected monthly cash flows were then discounted to present value using a risk-adjusted market rate for similar loans. For collateral dependent loans with deteriorated credit quality, fair value was estimated by analyzing the value of the underlying collateral, assuming the fair values of the loans were derived from the eventual sale of the collateral. These values were discounted using market derived rates of returns, with consideration given to the period of time and costs associated with the foreclosure and disposition of the collateral. There was no carryover of Legacy ConnectOne allowance for loan and lease losses associated with the loans that were acquired, as the loans were initially recorded at fair value on the date of the Merger. The acquired loan portfolio subject to purchased credit impairment accounting guidance (ASC 310-30) as of July 1, 2014 was comprised of collateral dependent loans with deteriorated credit quality as follows (in thousands): ASC 310-30 Contractual principal and accrued interest at acquisition $ 23,284 Principal not expected to be collected (non-accretable discount) (6,942 ) Expected cash flows at acquisition 16,342 Interest component of expected cash flows (accretable discount) (5,013 ) Fair value of acquired loans $ 11,329 The core deposit intangible asset recognized is being amortized over its estimated useful life of approximately 10 years utilizing the accelerated method. Other intangibles consist of below market rents, which are amortized over the remaining life of each lease using the straight-line method. Goodwill is not amortized for book purposes; however, it is reviewed at least annually for impairment and is not deductible for tax purposes. The fair value of retail demand and interest bearing deposit accounts was assumed to approximate the carrying value as these accounts have no stated maturity and are payable on demand. The fair value of time deposits was estimated by discounting the contractual future cash flows using market rates offered for time deposits of similar remaining maturities. The fair value of borrowed funds was estimated by discounting the future cash flows using market rates for similar borrowings. Direct acquisition and integration costs of the Merger were expensed as incurred and totaled $12.4 million for the full year 2014. These items were recorded as merger-related expenses on the statement of operations.

Earnings Per Share [Abstract]
Earnings Per Share [Text Block]	Note 4. Earnings per Common Share Basic earnings per common share is computed by dividing income available to common stockholders by the weighted average number of common shares outstanding. Diluted EPS includes any additional common shares as if all potentially dilutive common shares were issued (e.g., stock options). The Company’s weighted average common shares outstanding for diluted EPS include the effect of stock options and restricted stock awards outstanding using the Treasury Stock Method, which are not included in the calculation of basic EPS. Earnings per common share have been computed as follows: Three Months Ended Nine Months Ended (in thousands, except per share amounts) 2015 2014 2015 2014 Net income $ 10,842 $ 1,766 $ 31,743 $ 10,542 Less: preferred stock dividends (28 ) (28 ) (84 ) (84 ) Net income available to common stockholders $ 10,814 $ 1,738 31,659 10,458 Basic weighted average common shares outstanding 30,046 29,636 29,786 20,819 Plus: effect of dilutive options and awards 290 472 537 466 Diluted weighted average common shares outstanding 30,336 30,108 30,323 21,285 Earnings per common share: Basic $ 0.36 $ 0.06 $ 1.06 $ 0.50 Diluted 0.36 0.06 1.04 0.49

Investments, Debt and Equity Securities [Abstract]
Investments in Debt and Marketable Equity Securities (and Certain Trading Assets) Disclosure [Text Block]	Note 5. Investment Securities The Company’s investment securities are classified as available-for-sale and held-to-maturity at September 30, 2015 and December 31, 2014. Investment securities available-for-sale are reported at fair value with unrealized gains or losses included in equity, net of tax. Accordingly, the carrying value of such securities reflects their fair value as of September 30, 2015. 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 8 of the Notes to Consolidated Financial Statements for a further discussion. Transfers of debt securities from the available-for-sale category to the held-to-maturity category are made at fair value at the date of transfer. The unrealized holding gain or loss at the date of transfer remains in accumulated other comprehensive income and in the carrying value of the held-to-maturity investment security. Premiums or discounts on investment securities are amortized or accreted using the effective interest method over the life of the security as an adjustment of yield. Unrealized holding gains or losses that remain in accumulated other comprehensive income are amortized or accreted over the remaining life of the security as an adjustment of yield, offsetting the related amortization of the premium or accretion of the discount. The following tables present information related to the Company’s investment securities at September 30, 2015 and December 31, 2014.

FASB ASC 320-10 requires companies to record other-than-temporary impairment (“OTTI”) charges, through earnings, if they have the intent to sell, or more likely than not will be required to sell, an impaired debt security before recovery of its amortized cost basis. If the Company intends to sell or it is more likely than not it will be required to sell the security before recovery of its amortized cost basis, less any current period credit loss, the OTTI is recognized in earnings equal to the entire difference between the investment’s amortized cost basis and its estimated fair value at the balance sheet date. If the Company does not intend to sell the security and it is more likely than not that the entity will be required to sell the security before recovery of its amortized cost basis less any current period loss, and as such, it determines that a decline in fair value is other than temporary, the OTTI is separated into the amount representing the credit loss and the amount related to all other factors. The amount of the OTTI related to the credit loss is determined based on the present value of cash flows expected to be collected and is recognized in earnings. The amount of the total OTTI related to other factors is recognized in other comprehensive income, net of applicable taxes. The previous amortized cost basis less the OTTI recognized in earnings becomes the new amortized cost basis of the investment. 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 restructuring and/or filed for bankruptcy, has disclosed severe liquidity problems that cannot be resolved, disclosed deteriorating financial condition or sustained significant losses. The following table presents detailed information for each single issuer trust preferred security held by the Company at September 30, 2015, of which all but one has at least one rating below investment grade (in thousands): Lowest Gross Credit Amortized Fair Unrealized Rating Issuer Cost Value Gain (Loss) Assigned Countrywide Capital IV $ 1,771 $ 1,804 $ 33 BB+ Countrywide Capital V 2,747 2,829 82 BB+ Countrywide Capital V 250 257 7 BB+ Nationsbank Cap Trust III 1,576 1,426 (150 ) BB+ Morgan Stanley Cap Trust IV 2,500 2,537 37 BB Morgan Stanley Cap Trust IV 1,743 1,775 32 BB Goldman Sachs 1,000 1,149 149 BB Stifel Financial 4,500 4,545 45 BBB- Total $ 16,087 $ 16,322 $ 235 Temporarily Impaired Investments The Company does not believe that the unrealized losses, for all securities, which were comprised of 57 and 54 investment securities as of September 30, 2015 and December 31, 2014, 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- Factors affecting the market price include credit risk, market risk, 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 concentration of the investment portfolio including limits on concentrations to any one issuer. The Company believes the investment portfolio is prudently diversified. The decline in value is related to a change in interest rates and subsequent change in credit spreads required for these issues affecting market price. All issues are performing and are expected to continue to perform in accordance with their respective contractual terms and conditions. Short to intermediate average durations and in certain cases monthly principal payments should reduce further market value exposure to increases 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 September 30, 2015. In determining that the securities giving rise to the previously mentioned unrealized losses were not other than temporary, the Company evaluated the factors cited above, which the Company considers when assessing whether a security is other-than-temporarily impaired. In making these evaluations 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 September 30, 2015 and December 31, 2014: September 30, 2015 Total Less than 12 Months 12 Months or Longer Fair Unrealized Fair Unrealized Fair Unrealized (in thousands) Investment securities available-for-sale: Federal agency obligation $ 3,743 $ (7 ) $ 3,478 $ (5 ) $ 265 $ (2 ) Residential mortgage pass-through securities 2,283 (14 ) 2,162 (13 ) 121 (1 ) Trust preferred securities 1,426 (150 ) — — 1,426 (150 ) Corporate bonds and notes 8,389 (81 ) 6,437 (58 ) 1,952 (23 ) Asset-backed securities 19,628 (275 ) 18,359 (235 ) 1,269 (40 ) Certificates of deposit 220 (3 ) 220 (3 ) — — Equity securities 338 (38 ) — — 338 (38 ) Other securities 5,597 (97 ) — — 5,597 (97 ) Total $ 41,624 $ (665 ) $ 30,656 $ (314 ) $ 10,968 $ (351 ) Investment securities held-to-maturity: Federal agency obligation $ 5,443 $ (47 ) $ 4,614 $ (47 ) $ 829 $ — Residential mortgage pass-through securities 438 (1 ) 391 (1 ) 47 — Obligations of U.S. states and political subdivisions 7,313 (46 ) 7,313 (46 ) — — Corporate bonds and notes 2,670 (78 ) 2,670 (78 ) — — Total $ 15,864 $ (172 ) $ 14,988 $ (172 ) $ 876 $ — Total temporarily impaired securities $ 57,488 $ (837 ) $ 45,644 $ (486 ) $ 11,844 $ (351 ) December 31, 2014 Total Less than 12 Months 12 Months or Longer Fair Unrealized Fair Unrealized Fair Unrealized (in thousands) Investment securities available-for-sale: Federal agency obligation $ 6,755 $ (50 ) $ 2,770 $ (9 ) $ 3,985 $ (41 ) Residential mortgage pass-through securities 5,694 (11 ) 5,694 (11 ) — — Trust preferred securities 1,307 (269 ) — — 1,307 (269 ) Corporate bonds and notes 1,961 (11 ) 1,961 (11 ) — — Asset-backed securities 9,773 (31 ) 9,773 (31 ) — — Certificates of deposit 369 (2 ) 369 (2 ) — — Equity securities 307 (69 ) — — 307 (69 ) Other securities 5,417 (82 ) 1,978 (21 ) 3,439 (61 ) Total $ 31,583 $ (525 ) $ 22,545 $ (85 ) $ 9,038 $ (440 ) Investment securities held-to-maturity: Federal agency obligation $ 3,228 $ (28 ) $ 3,228 $ (28 ) $ — $ — Obligations of U.S. states and political subdivisions 8,341 (60 ) 1,401 (3 ) 6,940 (57 ) Corporate bonds and notes 993 (7 ) 993 (7 ) — — Total $ 12,562 $ (95 ) $ 5,622 $ (38 ) $ 6,940 $ (57 ) Total temporarily impaired securities $ 44,145 $ (620 ) $ 28,167 $ (123 ) $ 15,978 $ (497 ) Investment securities having a carrying value of approximately $142.8 million and $224.7 million at September 30, 2015 and December 31, 2014, respectively, were pledged to secure public deposits, borrowings, Federal Reserve Discount Window and Federal Home Loan Bank advances and for other purposes required or permitted by law.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments and Hedging Activities Disclosure [Text Block]	Note 6 - 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 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 while 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 swaps designated as cash flow hedges as of September 30, 2015 and 2014 and December 31, 2014 is presented in the following table.

Loans and the Allowance for Loa

Loans and the Allowance for Loan and Lease Losses	9 Months Ended

Receivables [Abstract]
Loans, Notes, Trade and Other Receivables Disclosure [Text Block]	Note 7. Loans and the Allowance for Loan and Lease Losses 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 and lease 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 and leases, 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 and leases: commercial (including lease financing), commercial real estate, commercial construction, residential real estate (including home equity) and consumer. Interest income on commercial, commercial real estate, commercial construction and residential loans are discontinued at the time the loan is 90 days delinquent unless the loan is well-secured and in 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 past due 90 days still on accrual include both smaller balance homogeneous loans that are collectively evaluated for impairment and individually classified impaired loans. A loan is moved to nonaccrual status in accordance with the Company’s policy, typically after 90 days of non-payment. All interest accrued but not received for loans placed on nonaccrual is 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 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 and lease 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 Losses The allowance for loan and lease losses is a valuation allowance for probable incurred credit losses. 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 and lease 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 impaired when, based on current information and events, it is probable that the Company will be unable to collect all amounts due according to the contractual terms of the loan agreement. Loans, for which the terms have been modified, and for which the borrower is experiencing financial difficulties, are considered troubled debt restructurings (“TDRs”) and classified as impaired. As part of the evaluation of impaired loans, the Company individually reviews for impairment all non-homogeneous loans internally classified as substandard or below. Generally, smaller impaired non-homogeneous loans and impaired homogeneous loans are collectively evaluated for impairment. The Bank has defined its population of impaired loans to include all loans on nonaccrual status; all troubled debt restructuring loans; and all loans (above an established dollar threshold of $250,000) internally classified as “Special Mention” or below that require a specific reserve. 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 and lease 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 class 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 purchases 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 the amount paid, such that there is no carryover of the seller’s allowance for loan and lease losses. After acquisition, losses are recognized by an increase in the allowance for loan and lease losses. Such purchased credit impaired loans are accounted for individually. 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). Over the life of the loan, expected cash flows continue to be estimated. If the present value of expected cash flows is less than the carrying amount, a loss is recorded. If the present value of expected cash flows is greater than the carrying amount, it is recognized as part of future interest income. Composition of Loan Portfolio The following table sets forth the composition of the Company’s loan portfolio, including net deferred loan fees, at September 30, 2015 and December 31, 2014: September 30, December 31, 2014 (in thousands) Commercial $ 569,605 $ 499,816 Commercial real estate 1,873,714 1,634,510 Commercial construction 283,623 167,359 Residential real estate 225,158 234,967 Consumer 3,569 2,879 Gross loans 2,955,669 2,539,531 Net deferred loan fees (2,288 ) (890 ) Total loans receivable $ 2,953,381 $ 2,538,641 At September 30, 2015 and December 31, 2014, loan balances of approximately $1.6 billion and $1.0 billion, respectively, were pledged to secure borrowings from the Federal Home Loan Bank of New York. Purchased Credit-Impaired Loans The Company holds purchased loans for which there was, at their acquisition date, evidence of deterioration of credit quality since their origination and it was probable, at acquisition, that all contractually required payments would not be collected. The carrying amount of those loans is as follows at September 30, 2015 and December 31, 2014. September 30, December 31, 2014 (in thousands) Commercial $ 7,046 $ 7,199 Commercial real estate 1,799 1,816 Residential real estate 323 806 Total carrying amount $ 9,168 $ 9,821 For those purchased loans disclosed above, the Company did not increase the allowance for loan and lease losses for the nine months ended September 30, 2015. The accretable yield, or income expected to be collected, on the purchased loans disclosed above for the three and nine months ended September 30, 2015 is as follows (in thousands): Three Months Three Months Nine Months Beginning balance $ 5,013 $ 4,678 $ 4,805 New loans purchased — — — Accretion of income (76 ) (53 ) (180 ) Reclassifications from nonaccretable difference — — — Disposals — — — Ending balance $ 4,937 $ 4,625 $ 4,625 The following table presents information about the recorded investment in loan receivables on nonaccrual status by segment at September 30, 2015 and December 31, 2014: Loans Receivable on Nonaccrual Status September 30, December 31, 2014 (in thousands) Commercial $ 5,051 $ 616 Commercial real estate 3,467 8,197 Commercial construction 1,479 — Residential real estate 2,891 2,796 Total loans receivable on nonaccrual status $ 12,888 $ 11,609 Nonaccrual loans and loans past due 90 days still on accrual include both smaller balance homogenous loans that are collectively evaluated for impairment and individually classified impaired loans. The Company continuously monitors the credit quality of its loans receivable. In addition to its internal staff, the Company utilizes the services of a third party loan review firm to rate the credit quality of its loans receivable. Credit quality is monitored by reviewing certain credit quality indicators. Assets classified “Pass” are deemed to possess average to superior credit quality, requiring no more than normal attention. Assets classified as “Special Mention” have generally acceptable credit quality yet possess higher risk characteristics/circumstances than satisfactory assets. Such conditions include strained liquidity, slow pay, stale financial statements, or other conditions that require more stringent attention from the lending staff. These conditions, if not corrected, may weaken the loan quality or inadequately protect the Company’s credit position at some future date. Assets are classified “Substandard” if the asset has a well-defined weakness that requires management’s attention to a greater degree than for loans classified special mention. Such weakness, if left uncorrected, could possibly result in the compromised ability of the loan to perform to contractual requirements. An asset is classified as “Doubtful” if it is inadequately protected by the net worth and/or paying capacity of the obligor or of the collateral, if any, that secures the obligation. Assets classified as doubtful include assets for which there is a “distinct possibility” that a degree of loss will occur if the inadequacies are not corrected.

The policy of the Company generally is to grant commercial, mortgage and consumer loans to residents and businesses within its 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 and lease losses are provided for all known and inherent risks. Collateral and/or personal guarantees are required for virtually all loans. A loan is considered to be in payment default once it is 90 days contractually past due under the modified terms. Loans modified in a troubled debt restructuring totaled a recorded investment of $77.1 million at September 30, 2015, of which $1.1 million were on nonaccrual status. The remaining loans modified were current and have complied with the terms of their restructure agreement. At December 31, 2014, loans modified in a troubled debt restructuring totaled $2.8 million, of which $1.0 million were on nonaccrual status. The remaining loans modified were current at the time of the restructuring and have complied with the terms of their restructure agreement. The Company has allocated $2.0 million in specific allocations with respect to loans whose loan terms had been modified in troubled debt restructurings as of September 30, 2015. There were no specific allocations with respect to troubled debt restructurings as of September 30, 2014. The TDRs presented as of September 30, 2015 increased the allowance for loan and lease losses by $2.0 million for the three and nine months ended September 30, 2015. The TDRs presented as of September 30, 2014 did not increase the allowance for loan and lease losses for the three and nine months ended September 30, 2014. The $2.0 million in specific allocations associated with taxi medallion lending referred to above was calculated based on the present value of estimated cash flows, including contractual debt interest service through maturity and principal repayments based on the fair value of the collateral, and excludes any consideration for the personal guarantees of borrowers, which provides an additional source of repayment but cannot be relied upon. The valuation per corporate medallion used for the calculation at September 30, 2015 was $814,000. A specific allocation was required at September 30, 2015 due to a decline in the valuation of taxi medallions from June 30, 2015, when there was no specific allocation required. The following table presents loans by class modified as troubled debt restructurings that occurred during the nine months ended September 30, 2015 (dollars in thousands): Pre-Modification Post-Modification Outstanding Outstanding Number of Recorded Recorded Loans Investment Investment Troubled debt restructurings: Commercial 47 $ 75,363 $ 75,363 Commercial real estate — — — Commercial construction — — — Residential real estate — — — Consumer — — — Total 47 $ 75,363 $ 75,363 The increase in TDRs was due to loans secured by New York City taxi medallions that were modified during the second quarter of 2015. 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 principle, 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 0 charge-offs in connection with a loan modification at the time of modification during the nine months ended September 30, 2015. There were 0 troubled debt restructurings for which there was a payment default within twelve months following the modification during the nine months ended September 30, 2015. The following table presents loans by class modified as troubled debt restructurings that occurred during the nine months ended September 30, 2014 (dollars in thousands): Pre-Modification Post-Modification Outstanding Outstanding Number of Recorded Recorded Loans Investment Investment Troubled debt restructurings: Commercial 1 $ 672 $ 315 Commercial real estate — — — Commercial construction — — — Residential real estate 1 53 51 Consumer — — — Total 2 $ 725 $ 366 The Company had a $333,000 charge-off in connection with a loan modification at the time of modification during the nine months ended September 30, 2014.

Fair Value Disclosures [Abstract]
Fair Value Disclosures [Text Block]	Note 8. Fair Value Measurements and Fair Value of Financial Instruments ASC Topic 820, “Fair Value Measurements and Disclosures,” establishes a fair value hierarchy that prioritizes the inputs to valuation techniques 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 are described below: 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. 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 September 30, 2015 and December 31, 2014: Securities available-for-sale Derivatives Loans held for sale Loans receivable Off-balance sheet financial instruments The fair value of financial standby letters of credit is based on fees currently charged for similar agreements or on the estimated cost to terminate them or otherwise settle the obligations with the counterparties. Assets and Liabilities Measured at Fair Value on a Recurring Basis 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 September 30, 2015 and December 31, 2014 are as follows: September 30, 2015 Fair Value Measurements at Reporting Date Using Quoted Prices Significant Significant (in thousands) Recurring fair value measurements: Assets Investment securities Available-for-sale Federal agency obligations $ 30,905 $ — $ 30,905 $ — Residential mortgage pass-through securities 48,091 — 48,091 — Commercial mortgage pass-through securities 3,055 — 3,055 — Obligations of U.S. states and political subdivision 8,382 — 8,382 — Trust preferred securities 16,322 — 16,322 — Corporate bonds and notes 78,386 — 78,386 — Asset-backed securities 21,130 — 21,130 — Certificates of deposit 1,920 — 1,920 — Equity securities 338 338 — — Other securities 15,685 15,685 — — Total available-for-sale 224,214 16,023 208,191 — Loans held for sale 990 — 990 — Total assets $ 225,204 $ 16,023 $ 209,181 $ — Liabilities Derivatives $ 1,105 $ — $ 1,105 $ — Total liabilities $ 1,105 $ — $ 1,105 $ — December 31, 2014 Fair Value Measurements at Reporting Date Using Quoted Prices Significant Significant (in thousands) Recurring fair value measurements: Assets Investment securities: Available-for-sale: Federal agency obligations $ 32,817 $ — $ 32,817 $ — Residential mortgage pass-through securities 60,356 — 60,356 — Commercial mortgage pass-through securities 3,046 — 3,046 — Obligations of U.S. states and political subdivision 8,406 — 8,406 — Trust preferred securities 16,306 — 16,306 — Corporate bonds and notes 125,777 — 125,777 — Asset-backed securities 27,502 — 27,502 — Certificates of deposit 2,123 — 2,123 — Equity securities 307 307 — — Other securities 12,892 12,892 — — Total available-for-sale 289,532 13,199 276,333 — Derivatives 48 — 48 — Total assets $ 289,580 $ 13,199 $ 276,381 $ — For the nine months ended September 30, 2015, there were no transfers of investment securities available-for-sale into or out of Level 1, Level 2, or Level 3 assets. Assets Measured at Fair Value on a Non-Recurring Basis For assets measured at fair value on a non-recurring basis, the unobservable inputs used to derive fair value measurements at September 30, 2015 and December 31, 2014 were as follows: September 30, 2015 Range Impaired loans Valuation Techniques Range of Unobservable Inputs Minimum Maximum Commercial Appraisals of collateral value Adjustment for age of comparable sales 0% 15% Commercial real estate Appraisals of collateral value Market capitalization rates, Market rental rates for similar properties 8% 12% December 30, 2014 Range Impaired loans Valuation Techniques Range of Unobservable Inputs Minimum Maximum Commercial Appraisals of collateral value Adjustment for age of comparable sales 0% 15% Commercial real estate Appraisals of collateral value Market capitalization rates, Market rental rates for similar properties 8% 12% Fair Value Measurements at Reporting Date Using Assets measured at fair value on a nonrecurring basis: September 30, 2015 Quoted Significant Significant Impaired loans (in thousands) Commercial $ 3,360 $ — $ — $ 3,360 Fair Value Measurements at Reporting Date Using Assets Measured at Fair Value on a Non-Recurring Basis December 31, Quoted Significant Significant Impaired loans (in thousands) Commercial $ 276 $ — $ — $ 276 Commercial real estate 3,369 — — 3,369 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 September 30, 2015 and December 31, 2014. Impaired loans Fair Value of Financial Instruments FASB ASC 825-10 requires all entities to disclose the estimated fair value of their financial instrument assets and liabilities. 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. Therefore, significant estimations and assumptions, as well as present value calculations, were used by the Company for the purposes of this disclosure. Cash and cash equivalents FHLB stock Investment securities held-to-maturity Loans Noninterest-bearing deposits Interest-bearing deposits Borrowings and subordinated debentures Accrued interest receivable/payable The following presents the carrying amount, fair value, and placement in the fair value hierarchy of the Company’s financial instruments as of September 30, 2015 and December 31, 2014.

For fixed-rate loan commitments, fair value also considers the difference between current market 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. 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 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.

Disclosure of Compensation Related Costs, Share-based Payments [Text Block]	Note 10. Stock-Based Compensation The Company’s stock-based compensation plans permit Parent Corporation common stock to be issued to key employees and directors of the Company and its subsidiaries. The options granted under the plans are intended to be either incentive stock options or non-qualified options. Under the 2009 Equity Incentive Plan, a total of 303,615 shares are available for grant and issuance as of September 30, 2015. In addition, a total of 114,327 shares remain available for grant and issuance under Legacy ConnectOne equity plans. Options may be exercised with shares issued from Treasury shares, newly issued shares or a combination of both. Options have been granted to purchase common stock at the fair market value of the stock at the date of grant. Options granted to date are exercisable after a three to five-year vesting period starting one year after the date of grant and generally expire ten years from the date of grant. Restricted shares granted to date have a vesting schedule ranging from one to three years. Stock-based compensation expense for share-based payment awards is based on the grant date fair value estimated on the date of grant. The Company recognizes compensation costs for those shares expected to vest on a straight-line basis over the requisite service period of the award, which is generally the option vesting term of three years. The Company estimates the forfeiture rate based on its historical experience during the preceding seven fiscal years. Under the principal stock-based compensation plans, the Company may also grant stock awards to certain employees. Stock awards are independent of option grants and are generally subject to forfeiture if employment terminates prior to the release of any applicable restrictions. During that period, ownership of the shares cannot be transferred. Restricted stock and stock awards that are fully vested at the time of grant have the same cash dividend and voting rights as other common stock and are considered to be currently issued and outstanding. The Company expenses the cost of stock awards, which is determined to be the fair market value of the shares at the date of grant, ratably over the period during which any restrictions lapse. There were 97,544 and 50,303 restricted stock awards outstanding at September 30, 2015 and December 31, 2014, respectively. These awards were issued with an award price equal to the market price of the Company’s common stock on the award date and with a three year vesting period. Forfeiture provisions exist for personnel that separate employment before the vesting period expires. There were 0 shares of common stock underlying options that were granted during the three and nine months ended September 30, 2015 and 2014, respectively. Options activity under the stock-based compensation plans as of September 30, 2015 and changes during the nine months ended September 30, 2015 were as follows: Shares Weighted- Weighted- Aggregate Outstanding at December 31, 2014 882,657 $ 5.65 Exercised (340,492 ) $ 4.19 Canceled/expired — Forfeited (4,731 ) Outstanding at September 30, 2015 537,434 $ 6.50 3.43 $ 6,878,825 Exercisable at September 30, 2015 532,636 $ 6.44 3.38 $ 6,829,750 The aggregate intrinsic value of options above represents the total pre-tax intrinsic value (the difference between the Company’s closing stock price on the last trading day of the third quarter of 2015 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 September 30, 2015. This amount changes based on the fair value of the Company’s stock. In conjunction with the plans above, the Company granted restricted shares to certain executive officers. Compensation expense is recognized over the vesting period of the awards based on the fair value of the stock at issue date. The fair value of the stock granted was based on the closing market price of the Company’s common stock as of the grant date. Generally, grants of restricted shares to date vest one-third, each, on the first, second and third anniversaries of the grant date. Nonvested Weighted- Nonvested at December 31, 2014 50,203 $ 11.79 Granted 67,906 18.50 Vested (20,565 ) 10.76 Forfeited/cancelled/expired — — Outstanding at September 30, 2015 97,544 $ 16.62 As of September 30, 2015, there was approximately $30,500 of total unrecognized compensation expense relating to unvested stock options. As of September 30, 2015, there was approximately $1,167,500 of total unrecognized compensation expense relating to unvested restricted stock awards. These costs are expected to be recognized over a weighted average period of 1.6 years. On April 30, 2015, the Company granted to various key employees performance unit awards (which are classified as equity awards), with each unit entitling the holder to one share of the Company’s common stock contingent upon the Company meeting or exceeding certain return on asset targets over the course of a three-year period ending April 30, 2018. Under the agreement, and assuming the Company has met or exceeded the applicable targets, grants of performance unit awards will vest on the third anniversary of the grant date or on an earlier date in the event of a change in control, as defined in the grant agreement. At September 30, 2015, the specific number of shares related to performance unit awards that were expected to vest was 94,585, determined by actual performance in consideration of the established range of the performance targets, which is consistent with the level of expense currently being recognized over the vesting period. Should this expectation change, additional compensation expense could be recorded in future periods or previously recognized expense could be reversed. The maximum amount of performance unit awards is 113,502. A summary of the status of unearned performance unit awards and the change during the period is presented in the table below: Shares Weighted- Unearned at June 30, 2015 94,585 $ 19.46 Awarded — — Forfeited — — Expired — — Unearned at September 30, 2015 94,585 $ 19.46 The Company recognized $256,000 in compensation expense related to the performance units for the quarter ended September 30, 2015. As of September 30, 2015, there was approximately $1,584,985 of unrecognized compensation expense related to unearned performance units. These costs are expected to be recognized over a period of 2.5 years.

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. Three of the FHLB notes ($2,500,000 and $7,500,000 each due April 2, 2018, and $5,000,000 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 while the REPOs are variable rate advances. The advances at September 30, 2015 were collateralized by approximately $1.1 billion of commercial mortgage loans, net of required over collateralization amounts, under a blanket lien arrangement. At September 30, 2015 the Company had remaining borrowing capacity of approximately $550 million.

Subordinated Borrowings [Abstract]
Subordinated Borrowings Disclosure [Text Block]	Note 13 - 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 I 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 September 30, 2015 was 3.15%. 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 September 30, 2015. Issuance Date Securities Issued Liquidation Value Coupon Rate Maturity Redeemable by Issuer Beginning 12/19/2003 $ 5,000,000 $1,000 per Capital Security Floating 3-month LIBOR + 285 Basis Points 01/23/2034 01/23/2009 The following table summarizes the mandatory redeemable trust preferred securities of the Company’s Statutory Trust II at December 31, 2014.

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 September 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 September 30, 2015, there were costs related to the debt issuance of $828,000. The net proceeds from the sale of the Notes will be used to redeem, on or before January 1, 2016, $11.3 million of Senior Noncumulative Perpetual Preferred Stock issued in 2011 to the U.S. Treasury under the Small Business Lending Fund Program, and for general corporate purposes, which included the Parent Corporation contributing $35.0 million of common equity to the Bank on September 30, 2015. In connection with the issuance of the Notes, the Parent Corporation obtained ratings from Kroll Bond Rating Agency (“KBRA”). KBRA assigned investment grade ratings of BBB- for the Company’s subordinated debt and a senior deposit rating of BBB+ for the Bank.

Accounting Policies [Abstract]
Consolidation, Policy [Policy Text Block]	The consolidated financial statements of ConnectOne Bancorp, Inc. (the “Parent Corporation”) are prepared on an accrual basis and include the accounts of the Parent Corporation and its wholly-owned subsidiary, ConnectOne Bank (the “Bank” and, collectively with the Parent Corporation and the Parent Corporation’s other direct and indirect subsidiaries, the “Company”). All significant intercompany accounts and transactions have been eliminated from the accompanying consolidated financial statements.
Use of Estimates, Policy [Policy Text Block]	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.
Basis of Accounting, Policy [Policy Text Block]	The consolidated financial statements have been prepared in conformity with U.S. generally accepted accounting principles (“U.S. GAAP”). Some items in the prior year financial statements were reclassified to conform to current presentation. Reclassifications had no effect on prior year net income or stockholders’ equity.
Interest Expense, Policy [Policy Text Block]	ASU No. 2015-03, “Interest—Imputation of Interest (Subtopic 835-30) Simplifying the Presentation of Debt Issuance Costs” requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The recognition and measurement guidance for debt issuance costs are not affected by the amendments in the ASU No. 2015-03. ASU No. 2015-03 will be effective for reporting periods (including interim periods) beginning after December 15, 2015. ASU No. 2015-03 became effective for the Company on January 1, 2015 and did not have a significant impact on its consolidated financial statements.
Fair Value of Financial Instruments, Policy [Policy Text Block]	Fair Value of Financial Instruments FASB ASC 825-10 requires all entities to disclose the estimated fair value of their financial instrument assets and liabilities. 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. Therefore, significant estimations and assumptions, as well as present value calculations, were used by the Company for the purposes of this disclosure.

Stock-Based Compensation (Details) [Line Items]
Share-based Compensation Arrangement by Share-based Payment Award, Award Vesting Rights				The Company’s stock-based compensation plans permit Parent Corporation common stock to be issued to key employees and directors of the Company and its subsidiaries. The options granted under the plans are intended to be either incentive stock options or non-qualified options. Under the 2009 Equity Incentive Plan, a total of 303,615 shares are available for grant and issuance as of September 30, 2015. In addition, a total of 114,327 shares remain available for grant and issuance under Legacy ConnectOne equity plans. Options may be exercised with shares issued from Treasury shares, newly issued shares or a combination of both.Options have been granted to purchase common stock at the fair market value of the stock at the date of grant. Options granted to date are exercisable after a three to five-year vesting period starting one year after the date of grant and generally expire ten years from the date of grant. Restricted shares granted to date have a vesting schedule ranging from one to three years.Stock-based compensation expense for share-based payment awards is based on the grant date fair value estimated on the date of grant. The Company recognizes compensation costs for those shares expected to vest on a straight-line basis over the requisite service period of the award, which is generally the option vesting term of three years. The Company estimates the forfeiture rate based on its historical experience during the preceding seven fiscal years.
