Disclosure Text Block [Abstract]
Nature of Business, Basis of Financial Statement Presentation and Summary of Significant Accounting Policies	Note 1a – Nature of Business, Basis of Financial Statement Presentation and 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 New Jersey 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), NJCB Spec-1, LLC (a New Jersey limited liability company) and BoeFly, Inc. (a New Jersey online business lending marketplace). 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-seven 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. Principals of Consolidation 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. Risks and Uncertainties As previously disclosed, on March 11, 2020, the World Health Organization declared the outbreak of COVID-19 as a global pandemic, which continues to spread throughout the United States and around the world. On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security Act - 59 - Table of Contents CONNECTONE BANCORP, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS Note 1a – Nature of Business, Basis of Financial Statement Presentation and Summary of Significant Accounting Policies – (continued) Federal Reserve reductions in interest rates and other effects of the COVID-19 pandemic may adversely affect the Company's financial condition and results of operations in future periods. It is unknown how long the adverse conditions associated with the COVID-19 pandemic will last and what the complete financial effect will be to the Company. It is reasonably possible that estimates made in the financial statements could be materially and adversely impacted in the near term as a result of these conditions, including the determination of the allowance for loan losses, fair value of financial instruments, impairment of goodwill and other intangible assets and income taxes. 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. Equity Securities The Company’s equity securities are recorded at fair value, with unrealized gains and losses included in earnings beginning January 1, 2018 after adoption of Accounting Standards Update No. 2016-01, “Financial Instruments – Overall: Recognition and Measurement of Financial Assets and Financial Liabilities. 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. - 60 - Table of Contents CONNECTONE BANCORP, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS Note 1a – Nature of Business, Basis of Financial Statement Presentation and Summary of Significant Accounting Policies – (continued) 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, purchase premium and discounts 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 are 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 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 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. Loans for which the terms have been modified as a concession to the borrower due to the borrower experiencing financial difficulties (other than with regard to loans meeting the requirements of the CARES Act or regulatory guidance regarding mitigating the impact of the COVID-19 pandemic) 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 of $250,000 and over are individually evaluated for impairment. If a loan 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. - 61 - Table of Contents CONNECTONE BANCORP, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS Note 1a – Nature of Business, Basis of Financial Statement Presentation and Summary of Significant Accounting Policies – (continued) 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 - 62 - Table of Contents CONNECTONE BANCORP, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS Note 1a – Nature of Business, Basis of Financial Statement Presentation and Summary of Significant Accounting Policies – (continued) 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. - 63 - Table of Contents CONNECTONE BANCORP, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS Note 1a – Nature of Business, Basis of Financial Statement Presentation and Summary of Significant Accounting Policies – (continued) 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 30 years. Leasehold improvements are depreciated using the straight-line method over the terms of the respective leases, or the estimated useful lives of the improvements, whichever is shorter. Furniture, fixtures and equipment are depreciated using the straight-line method with useful lives ranging from 3 to 10 years. Leases Leases are classified as operating or finance leases at the lease commencement date. Lease expense for operating leases and short-term leases is recognized on a straight-line basis over the lease team. The Company includes lease extension and termination options in the lease term if, after considering relevant economic factors, it is reasonably certain the Company will exercise the option. Right-of-use assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. Right-of-use assets and lease liabilities are recognized at the lease commencement date based on the estimated present value of the lease payments over the lease term. The Company uses its incremental borrowing rate at lease commencement to calculate the present value of lease payments when the rate implicit in a lease is not known. The Company has elected not to recognize leases with original terms of 12 months or less on the consolidated balance sheet. 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. - 64 - Table of Contents CONNECTONE BANCORP, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS Note 1a – Nature of Business, Basis of Financial Statement Presentation and Summary of Significant Accounting Policies – (continued) 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. See Note 18 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 year ended December 31, 2020 and December 31, 2019, the Parent Corporation repurchased 54,693 and 540,018 shares under a board-approved share repurchase program. During the year ended December 31, 2018, the Parent Corporation did not repurchase any of its shares. Goodwill Goodwill arises from business combinations and is generally determined as 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 exist 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 as of the years ended December 31, 2020, 2019 and 2018. Other Intangible Assets Other intangible assets consist of core deposit intangibles 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 (loss) 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. - 65 - Table of Contents CONNECTONE BANCORP, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS Note 1a – Nature of Business, Basis of Financial Statement Presentation and Summary of Significant Accounting Policies – (continued) 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 2019 and 2018 to conform to the classifications presented in 2020. Such reclassifications had no impact on net income or stockholders’ equity.

Accounting Changes and Error Corrections [Abstract]
Authoritative Accounting Guidance	Note 1b – Authoritative Accounting Guidance Adoption of New Accounting Standards in 2021 ASU No. 2016-13, “Financial Instruments – Credit Losses (Topic 326): Assets Measured at Amortized Cost.” (modified by ASU 2018-19, ASU 2019-04 and ASU 2019-05). ASU 2016-13 requires a financial asset (or a group of financial assets) measured at amortized cost basis to be presented at the net amount expected to be collected. The amendments in this update replace the incurred loss impairment methodology in current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates and affects loans, debt securities, trade receivables, off-balance-sheet credit exposures, reinsurance receivables, and any other financial assets not excluded from the scope that have the contractual right to receive cash. For SEC filers that are not smaller reporting companies, the amendments in this update are effective for the fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. In December 2018, the OCC, the Board of Governors of the Federal Reserve System, and the FDIC approved a final rule to address changes to credit loss accounting under GAAP, including banking organizations’ implementation of ASU No. 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“CECL”). Under the CARES Act, the effective date for the implementation of ASU No. 2016-13 was delayed until the earlier of the end of the health crises caused by the COVID-19 Pandemic or December 31, 2020. The Economic Aid Act then further delayed implementation until the earlier of the end of the health crises caused by the COVID-19 Pandemic or December 31, 2022. The Company is adopting Topic 326, as of January 1, 2021. While the Company has not finalized the impact of implementing CECL, the Company expects to recognize a one-time cumulative effect adjustment to the allowance and beginning retained earnings, net of tax, upon adoption. The future impact of CECL on the Company’s allowance for credit losses and provision expense subsequent to the initial adoption will depend on changes in the loan portfolio, economic conditions and refinements to key assumptions including forecasting and qualitative factors. The Company measured its allowance under its current incurred loan loss model as of December 31, 2020.

Business combinations:
Business Combination	Note 2 – Business Combination On January 2, 2020, Bancorp of New Jersey, Inc. (“BNJ”) merged with and into the Company, with the Company as the surviving entity. As a result of the merger, the Company acquired nine branch offices all located in Bergen County, New Jersey. Subject to the allocation and proration procedures set forth in the merger agreement, holders of BNJ common stock had the right to elect, with respect to each share of BNJ common stock, to receive either (i) $16.25 in cash or (ii) 0.780 of a share of Company common stock (plus cash in lieu of any fractional shares of Company common stock to which such holder would otherwise be entitled). The allocation and proration procedures set forth in the merger agreement required that approximately 20% of the shares of BNJ common stock be converted into cash and the remaining approximately 80% of BNJ common shares be converted into shares of the Company’s common stock. - 67 - Table of Contents CONNECTONE BANCORP, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS Note 2 – Business Combination – (continued) The acquisition of BNJ was accounted for using the acquisition method of accounting and, accordingly, assets acquired, liabilities assumed, and consideration paid were recorded at their estimated fair values as of the acquisition date. The application of the acquisition method of accounting resulted in the recognition of goodwill of $45.8 million and a core deposit intangible of $8.1 million. The assets acquired and liabilities assumed, and consideration paid in the acquisition of BNJ were recorded at their estimated fair values based on management’s best estimates using information available at the date of the acquisition. In connection with the acquisition, the consideration paid, and the fair value of identifiable assets acquired, and liabilities assumed as of the date of acquisition are summarized in the following table: Estimated FairValue at January 2, 2020 (in thousands) Consideration paid: Common stock issued in acquisition $ 118,375 Cash paid in acquisition 23,977 Total consideration paid: 142,352 Assets acquired Cash and cash equivalents 111,368 Securities available-for-sale 20,073 Loans, net 774,720 Premises and equipment, net 12,826 Accrued interest receivable 2,910 Core deposit intangibles 8,076 Other assets 19,309 Total assets acquired 949,282 Liabilities assumed Deposits 785,378 Borrowings 49,742 Other liabilities 17,608 Total liabilities assumed 852,728 Net assets acquired 96,554 Goodwill recorded in acquisition $ 45,798 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. Loans acquired in the BNJ acquisition were recorded at fair value, and there was no carryover related allowance for loan losses. The fair values of loans acquired from BNJ were estimated based on the value of the expected cash flows, which were projected based on the contractual terms of the loans, including both maturity and contractual amortization. The monthly principal and interest cash flows were adjusted for expected losses and prepayments, where appropriate. Expected losses assumptions were developed using peer group loss data. Projected cash flows were then discounted to present value using a discount rate developed based on the relative risk of the cash flows, considering the loan type, liquidity risk, the maturity of the loans, servicing costs and a required return on capital. - 68 - Table of Contents CONNECTONE BANCORP, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS Note 2 – Business Combination – (continued) The following is a summary of the loans accounted for in accordance with ASC 310-30 that were acquired in the BNJ acquisition as of the Merger date: Estimated FairValue at January 2, 2020 (in thousands) Contractually required principal and interest acquisition $ 14,416 Contractual cash flows not expected to be collected (non-accretable discount) (2,111 ) Expected cash flows at acquisition 12,305 Interest component of expected cash flows (accretable discount) (605 ) Fair value of acquired loans $ 11,700 Goodwill related to BNJ 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 those 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 BNJ acquisition were expensed as incurred. These items were recorded as merger expenses on the consolidated statement of income. During the year ended December 31, 2020, merger expenses related to the BNJ acquisition were $11.6 million.

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 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, 2020 2019 2018 (in thousands, except per share amounts) Net income available to common stockholders $ 71,289 $ 73,395 $ 60,352 Earnings allocated to participating securities (356) (295) (139) Income attributable to common stock $ 70,933 $ 73,100 $ 60,213 Weighted average common shares outstanding, including participating securities 39,643 35,289 32,198 Weighted average participating securities (131) (84) (74) Weighted average common shares outstanding 39,512 35,205 32,124 Incremental shares from assumed conversions of options, restricted stock units, performance units and restricted stock 132 88 233 Weighted average common and equivalent shares outstanding 39,644 35,293 32,357 Earnings per common share: Basic $ 1.80 $ 2.08 $ 1.87 Diluted 1.79 2.07 1.86 There were no antidilutive common share equivalents as of December 31, 2020, 2019 and 2018.

Investments, Debt and Equity Securities [Abstract]
Investment Securities	Note 4 – Investment Securities The Company’s investment securities are classified as available-for-sale as of December 31, 2020 and December 31, 2019. 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, 2020 and December 31, 2019. 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 21 of the Notes to Consolidated Financial Statements for a further discussion.

AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS Note 4 – Investment Securities – (continued) 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 21 and 53 securities as of December 31, 2020 and December 31, 2019, respectively, represent an other-than-temporary impairment (“OTTI”). The gross unrealized losses associated with U.S. Treasury and agency securities, federal agency obligations, mortgage-backed securities, corporate bonds, tax-exempt securities, and asset-backed securities are not considered to be other-than-temporary because 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 securities portfolio including limits on concentrations to any one issuer. The Company believes the securities 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 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. 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 OTTI 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, a security is subject to numerous risks as cited above. - 72 - Table of Contents CONNECTONE BANCORP, INC.

Loans and the Allowance for Loan Losses	Note 5 – Loans and the Allowance for Loan Losses Loans Receivable : 2020 2019 (dollars in thousands) Commercial (1) $ 1,521,967 $ 1,129,661 Commercial real estate 3,783,550 3,041,959 Commercial construction 617,747 623,326 Residential real estate 322,564 320,020 Consumer 1,853 3,328 Gross loans 6,247,681 5,118,294 Net deferred fees (11,374) (4,767) Loans receivable $ 6,236,307 $ 5,113,527 (1) Included in commercial loans as of December 31, 2020 were PPP loans of $397.5 million. As of December 31, 2020, and 2019, loan balances of approximately $2.7 billion and $2.5 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. • The Company considers loan classes and loan segments to be one and the same.

A summary of the activity in the allowance for loan losses by loan segment is as follows: Commercial Commercial real estate Commercial construction Residential real estate Consumer Unallocated Total (dollars in thousands) Balance as of January 1, 2020 $ 8,349 $ 20,853 $ 7,304 $ 1,685 $ 3 $ 99 $ 38,293 Loan charge-offs (552) - - (341) (7) - (900) Recoveries 4 802 - 23 4 - 833 Provision for loan losses 20,642 17,675 890 1,320 4 469 41,000 Balance as of December 31, 2020 $ 28,443 $ 39,330 $ 8,194 $ 2,687 $ 4 $ 568 $ 79,226 Commercial Commercial real estate Commercial construction Residential real estate Consumer Unallocated Total (dollars in thousands) Balance as of January 1, 2019 $ 9,875 $ 18,847 $ 4,519 $ 1,266 $ 2 $ 445 $ 34,954 Loan charge-offs ( 1,029 ) (3,470) - (557) (20) - (5,076) Recoveries 265 30 - 3 17 - 315 Provision for loan losses ( 762 ) 5,446 2,785 973 4 (346) 8,100 Balance as of December 31, 2019 $ 8,349 $ 20,853 $ 7,304 $ 1,685 $ 3 $ 99 $ 38,293 Commercial Commercial real estate Commercial construction Residential real estate Consumer Unallocated Total (dollars in thousands) Balance as of January 1, 2018 $ 8,233 $ 17,112 $ 4,747 $ 1,050 $ 1 $ 605 $ 31,748 Loan charge-offs (17,066) (915) - (23) (7) - (18,011) Recoveries 109 - - 2 6 - 117 Provision for loan losses 18,599 2,650 (228) 237 2 (160) 21,100 Balance as of December 31, 2018 $ 9,875 $ 18,847 $ 4,519 $ 1,266 $ 2 $ 445 $ 34,954 For the year ended December 31, 2018, the loan charge-offs within the commercial loan segment were primarily made up of $17.0 million in charge-offs related to the taxi medallion portfolio. Troubled Debt Restructurings Loans are considered to have been modified in a troubled debt restructuring (“TDRs”) when, except as discussed below, 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. As of December 31, 2020, 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. - 81 - Table of Contents CONNECTONE BANCORP, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS Note 5 – Loans and the Allowance for Loan Losses – (continued) As of December 31, 2020, TDRs totaled $49.4 million, of which $25.7 million were on nonaccrual status and $23.7 million were performing under their restructured terms. As of December 31, 2019, TDRs totaled $52.0 million, of which $30.6 million were on nonaccrual status and $21.4 million were performing under their restructured terms. The Company has allocated $-0- and $1.3 million of specific allowance as of December 31, 2020 and December 31, 2019, respectively. There were no charge-offs in connection with a loan modification at the time of modification during the year ended December 31, 2020, 2019 and 2018. There were no TDRs for which there was a payment default within twelve months following the modification during the year ended December 31, 2020, 2019 and 2018. The following table presents loans by class modified as TDRs that occurred during year ended December 31, 2020: Number of Loans Pre-Modification Outstanding Recorded Investment Post-Modification Outstanding Recorded Investment (dollars in thousands) Troubled debt restructurings: Commercial 1 $ 188 $ 188 Commercial real estate 1 93 93 Commercial construction 1 4,021 4,021 Residential real estate 2 2,184 2,184 Total 5 $ 6,486 $ 6,486 The five loan modifications during the year ended December 31, 2020 were maturity extensions.

All 27 taxi medallion loans included above were on nonaccrual status prior to modification and remain on nonaccrual status post-modification. All loan modifications during the year ended December 31, 2018 included interest rate reductions and/or maturity extensions. In March 2020, various regulatory agencies, including the Board of Governors of the Federal Reserve System and the Federal Deposit Insurance Corporation, (“the agencies”) issued an interagency statement on loan modifications and reporting for financial institutions working with customers affected by COVID-19. The interagency statement was effective immediately and impacted accounting for loan modifications. The agencies confirmed with the staff of the FASB that short-term modifications made on a good faith basis in response to COVID-19 to borrowers who were current prior to any relief, are not to be considered TDRs. This includes short-term (e.g., three to six months) modifications such as payment deferrals, fee waivers, extensions of repayment terms, or other delays in payment that are insignificant. Provisions of the CARES Act largely mirrored the provisions of the interagency statement, providing that modified loans would not be considered TDR’s if they were performing at year-end 2019, and the other conditions set forth in the interagency statement were met. Borrowers considered current are those that are less than 30 days past due on their contractual payments at the time a modification program is implemented or at year-end 2019. As of December 31, 2020, the Bank had 113 deferred loans totaling approximately $207.1 million. The majority of these loans were deferred between 90 and 120 days. The following table sets forth the composition of these loans by loan segments as of December 31, 2020: Number of Loans Unpaid Principal Balance (dollars in thousands) Commercial 49 $ 17,637 Commercial real estate 63 188,778 Residential real estate 1 666 Total 113 $ 207,081 As of December 31, 2020, there were no deferred loans that were delinquent or on nonaccrual status. As of December 31, 2020, $40.3 million of deferred loans were risk rated “special mention” or worse. The Company evaluates its deferred loans after the initial deferral period and will either return the deferred loans to its original loan terms or the loan will be reassessed at that time to determine if a further deferment should be granted and if a downgrade in risk rating is appropriate.

Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill and Other Intangible Assets	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. In accordance with ASC 350, the Company performs goodwill impairment test at least annually, or more frequently if triggering event occurs. In the second quarter of 2020, the impact of COVID-19, prompted the Company to quantitively evaluate goodwill for impairment. The Company engaged an independent third-party to evaluate the fair value of the Company compared to its carrying value. To estimate the fair value of the Company, the third-party relied on a weighted discounted cash flow method, guideline public company method, and transaction method. The results concluded that the fair value of the Company exceeded its current carrying value and goodwill impairment did not exist as of June 30, 2020. Based upon management’s review through December 31, 2020, the Company’s goodwill was not impaired. Management concludes that the ASC 350 goodwill step zero test has been passed, and no further testing is required.

Subordinated Debentures	Note 10 – 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 as of December 31, 2020 was 3.06%. 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 as of December 31, 2020 and December 31, 2019. 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 On June 10, 2020, the Parent Corporation issued $75 million in aggregate principal amount of fixed-to-floating rate subordinated notes (the “2020 Notes”). The 2020 Notes bear interest at 5.75% annually from, and including, the date of initial issuance to, but excluding, June 15, 2025 or the date of earlier redemption, payable semi-annually in arrears on June 15 and December 15 of each year, commencing December 15, 2020. From and including June 15, 2025 through maturity or earlier redemption, the interest rate shall reset quarterly to an interest rate per annum equal to a benchmark rate, which is expected to be Three-Month Term SOFR (as defined in the Second Supplemental Indenture), plus 560.5 basis points, payable quarterly in arrears on March 15, June 15, September 15 and December 15 of each year, commencing on September 15, 2025. Notwithstanding the foregoing, if the benchmark rate is less than zero, then the benchmark rate shall be deemed to be zero. On January 11, 2018, the Parent Corporation issued $75 million in aggregate principal amount of fixed-to-floating rate subordinated notes (the “2018 Notes”). The 2018 Notes bear interest at 5.20% annually from, and including, the date of initial issuance to, but excluding, February 1, 2023, payable semi-annually in arrears. From and including February 1, 2023 through maturity or earlier redemption, the interest rate shall reset quarterly to an interest rate per annum equal to the then current three-month LIBOR rate plus 284 basis points (2.84%) payable quarterly in arrears. If three-month LIBOR is not available for any reason, then the rate for that interest period will be determined by such alternate method as provided in the Supplemental Indenture. Interest on the 2018 Notes will be paid on February 1, and August 1, commencing August 1, 2018 to but not including February 1, 2023, and from and including February 1, 2023, on February 1, May 1, August 1, and November 1, of each year to but excluding the stated maturity date, unless in any case previously redeemed. During June 2015, the Parent Corporation issued $50 million in aggregate principal amount of fixed-to-floating rate subordinated notes (the “2015 Notes”). As of December 31, 2020, the 2015 Notes have a stated maturity of July 1, 2025, and bear interest until the maturity date or early redemption date at a variable rate equal to the then current three-month LIBOR rate plus 393 basis points. As of December 31, 2020, the variable interest rate was 4.16% and all costs related to 2015 issuance have been amortized. The 2015 Notes were redeemed in full on January 1, 2021.

The legislation imposes a temporary surtax on corporations earning New Jersey allocated income in excess of $1 million of 2.5% for tax years beginning on or after January 1, 2018 through December 31, 2019, and of 1.5% for tax years beginning on or after January 1, 2020 through December 31, 2021. However, in 2020, this surtax was extended through December 31, 2023, at the 2.5% level. The legislation also requires combined filing for members of an affiliated group for tax years beginning on or after January 1, 2019, changing New Jersey’s current status as a separate return state, and limits the deductibility of dividends received.

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 2020 and 2019, 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 2017 tax return year and forward. The Company’s state income tax returns are generally open from the 2015 and later tax return years based on individual state statutes of limitations.

Offsetting [Abstract]
Offsetting Assets and Liabilities	Note 12 – 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 20 within this section.

Commitments and Contingencies Disclosure [Abstract]
Commitments, Contingencies and Concentrations of Credit Risk	Note 13 – 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 as of December 31, 2020 and 2019: 2020 2019 (dollars in thousands) Commitments under commercial loans and lines of credit $ 525,606 $ 564,444 Home equity and other revolving lines of credit 65,690 47,278 Outstanding commercial mortgage loan commitments 327,745 392,225 Standby letters of credit 28,738 32,155 Overdraft protection lines 1,020 752 Total $ 948,799 $ 1,036,854 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 and Regulatory Requirements	Note 15 – 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 net unrealized gain or loss on available for sale securities is not included in computing regulatory capital. Management believes as of December 31, 2020, 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 an institution is classified as adequately capitalized or lower, 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, 2020, and 2019, 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, 2020 and 2019, compared to the FRB and FDIC minimum capital adequacy requirements and the FDIC requirements for classification as a well-capitalized institution.

Pension and Other Benefits	CONNECTONE BANCORP, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS Note 17 – Pension and Other Benefits Defined Benefit Plans The Company maintains a frozen noncontributory pension plan covering employees of the Company prior to the merger with Legacy ConnectOne. 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.

This data forms the basis for the construction of a best-estimate range of real investment returns 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. - 97 - Table of Contents CONNECTONE BANCORP, INC.

Share-based Payment Arrangement [Abstract]
Stock Based Compensation	Note 18 – 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, 2020. 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, 2020 are approximately 435,674. The Company intends to issue all shares under the Plan in the form of newly issued shares. Restricted stock, options and restricted stock units 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 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, performance units and restricted stock units do not. All awards are issued at the fair value of the underlying shares at the grant date. The Company expenses the cost of the awards, which is determined to be the fair market value of the awards at the date of grant, ratably over the vesting period. Forfeiture rates are not estimated but are recorded as incurred. Stock-based compensation expense was $2.9 million, $2.7 million and $1.9 million for the years ended December 31, 2020, 2019 and 2018 respectively. Activity under the Company’s options for the year ended December 31, 2020 was as follows: Number of Stock Options Weighted- Average Exercise Price Weighted- Average Remaining Contractual Term (in years) Aggregate Intrinsic Value Outstanding as of December 31, 2019 73,426 $ 8.19 0 $ 0 Granted - - Exercised ( 35,413 ) 7.28 Forfeited/cancelled/expired - - Outstanding as of December 31, 2020 38,013 9.04 1.2 $ 409,000 Exercisable as of December 31, 2020 38,013 $ 9.04 1.2 $ 409,000 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, 2020 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, 2020. This amount changes based on the fair market value of the Company’s stock.

The cost is expected to be recognized over a weighted average period of 1.3 years. A summary of the status of unearned performance unit awards and the change during the period is presented in the table below: Units (expected) Units (maximum) Weighted Average Grant Date Fair Value Unearned as of December 31, 2019 90,097 0 $ 23.85 Awarded 82,579 10.77 Change in estimate 12,297 29.61 Vested shares (37,337) 22.75 Unearned as of December 31, 2020 147,636 206,744 $ 17.29 As of December 31, 2020, the specific number of shares related to performance units that were expected to vest was 147,636 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. As of December 31, 2020, the maximum number of shares related to performance units that ultimately could vest if performance targets were exceeded is 206,744. During the year ended December 31, 2020, 37,337 shares vested. A total of 14,935 shares were netted from the vested shares to satisfy employee tax obligations. The net shares issued from vesting of performance units during the year ended December 31, 2020 were 22,402 shares. As of December 31, 2020, compensation cost of approximately $1.0 million related to non-vested performance units not yet recognized is expected to be recognized over a weighted-average period of 1.7 years. A summary of the status of unearned restricted stock units and the changes in restricted stock units during the period is presented in the table below: Units (expected) Weighted Average Grant Date Fair Value Unearned as of December 31, 2019 73,069 $ 23.62 Awarded 123,870 10.77 Vested shares (27,626) 24.53 Unearned as of December 31, 2020 169,313 $ 14.07 Any forfeitures would result in previously recognized expense being reversed. A portion of the shares that vest will be netted out to satisfy the tax obligations of the recipient. During the year ended December 31, 2020, 27,626 shares vested. A total of 11,085 shares were netted from the vested shares to satisfy employee tax obligations. The net shares issued from vesting of restricted stock units during the year ended December 31, 2020 were 16,541 shares. As of December 31, 2020, compensation cost of approximately $1.5 million related to non-vested restricted stock units, not yet recognized, is expected to be recognized over a weighted-average period of 1.8 years.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives	Note 20 – 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, January 27, 2020 and March 3, 2020 each with a respective notional amount of $25.0 million and were designated as a cash flow hedge of a Federal Home Loan Bank (“FHLB”) advance. In addition, interest rate swaps were entered into on June 4, 2019 and August 6, 2019, each with a respective notional amount of $50.0 million and were designated as a cash flow hedge of a FHLB 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).

Fair Value Disclosures [Abstract]
Fair Value Measurements and Fair Value of Financial Instruments	Note 21 – 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 as of December 31, 2020 and December 31, 2019: Securities Available-for-Sale: - 104 - Table of Contents CONNECTONE BANCORP, INC.

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. - 109 - Table of Contents CONNECTONE BANCORP, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS Note 21 – Fair Value Measurements and Fair Value of Financial Instruments – (continued) Fair values for financial instruments must be estimated by management using techniques such as discounted cash flow analysis and comparison to similar instruments. These estimates are highly subjective and require judgments regarding significant matters, such as the amount and timing of future cash flows and the selection of discount rates that appropriately reflect market and credit risks. Changes in these judgments often have a material effect on the fair value estimates. Since these estimates are made as of a specific point in time, they are susceptible to material near-term changes. Fair values disclosed in accordance with ASC Topic 825 do not reflect any premium or discount that could result from the sale of a large volume of a particular financial instrument, nor do they reflect possible tax ramifications or estimated transaction costs.

AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS Note 21 – Fair Value Measurements and Fair Value of Financial Instruments – (continued) The fair value of commitments to originate loans is estimated using the fees currently charged to enter into similar agreements, considering the remaining terms of the agreements and the present creditworthiness of the counterparties. 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.

Accounting Policies [Abstract]
Business	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 New Jersey 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), NJCB Spec-1, LLC (a New Jersey limited liability company) and BoeFly, Inc. (a New Jersey online business lending marketplace). 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-seven 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.
Principals of Consolidation	Principals of Consolidation 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	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	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.
Risks and Uncertainties	Risks and Uncertainties As previously disclosed, on March 11, 2020, the World Health Organization declared the outbreak of COVID-19 as a global pandemic, which continues to spread throughout the United States and around the world. On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security Act - 59 - Table of Contents CONNECTONE BANCORP, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS Note 1a – Nature of Business, Basis of Financial Statement Presentation and Summary of Significant Accounting Policies – (continued) Federal Reserve reductions in interest rates and other effects of the COVID-19 pandemic may adversely affect the Company's financial condition and results of operations in future periods. It is unknown how long the adverse conditions associated with the COVID-19 pandemic will last and what the complete financial effect will be to the Company. It is reasonably possible that estimates made in the financial statements could be materially and adversely impacted in the near term as a result of these conditions, including the determination of the allowance for loan losses, fair value of financial instruments, impairment of goodwill and other intangible assets and income taxes.
Cash and Cash Equivalents	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	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.
Equity Securities	Equity Securities The Company’s equity securities are recorded at fair value, with unrealized gains and losses included in earnings beginning January 1, 2018 after adoption of Accounting Standards Update No. 2016-01, “Financial Instruments – Overall: Recognition and Measurement of Financial Assets and Financial Liabilities.
Loans Held-for-Sale	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. - 60 - Table of Contents CONNECTONE BANCORP, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS Note 1a – Nature of Business, Basis of Financial Statement Presentation and Summary of Significant Accounting Policies – (continued) 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 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, purchase premium and discounts 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 are 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 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 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	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. Loans for which the terms have been modified as a concession to the borrower due to the borrower experiencing financial difficulties (other than with regard to loans meeting the requirements of the CARES Act or regulatory guidance regarding mitigating the impact of the COVID-19 pandemic) 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 of $250,000 and over are individually evaluated for impairment. If a loan 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. - 61 - Table of Contents CONNECTONE BANCORP, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS Note 1a – Nature of Business, Basis of Financial Statement Presentation and Summary of Significant Accounting Policies – (continued) 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
Purchased Credit-Impaired 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	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	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 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 30 years. Leasehold improvements are depreciated using the straight-line method over the terms of the respective leases, or the estimated useful lives of the improvements, whichever is shorter. Furniture, fixtures and equipment are depreciated using the straight-line method with useful lives ranging from 3 to 10 years.
Leases	Leases Leases are classified as operating or finance leases at the lease commencement date. Lease expense for operating leases and short-term leases is recognized on a straight-line basis over the lease team. The Company includes lease extension and termination options in the lease term if, after considering relevant economic factors, it is reasonably certain the Company will exercise the option. Right-of-use assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. Right-of-use assets and lease liabilities are recognized at the lease commencement date based on the estimated present value of the lease payments over the lease term. The Company uses its incremental borrowing rate at lease commencement to calculate the present value of lease payments when the rate implicit in a lease is not known. The Company has elected not to recognize leases with original terms of 12 months or less on the consolidated balance sheet.
Other Real Estate Owned	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	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-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. See Note 18 of the Notes to Consolidated Financial Statements for a further discussion.
Treasury Stock	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 year ended December 31, 2020 and December 31, 2019, the Parent Corporation repurchased 54,693 and 540,018 shares under a board-approved share repurchase program. During the year ended December 31, 2018, the Parent Corporation did not repurchase any of its shares.
Goodwill	Goodwill Goodwill arises from business combinations and is generally determined as 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 exist 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 as of the years ended December 31, 2020, 2019 and 2018.
Other Intangible Assets	Other Intangible Assets Other intangible assets consist of core deposit intangibles arising from business combinations that are amortized over their estimated useful lives to their estimated residual value.
Comprehensive Income	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 (loss) 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	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	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 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	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 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	Advertising Costs The Company recognizes its marketing and advertising cost as incurred.
Reclassifications	Reclassifications Certain reclassifications have been made in the consolidated financial statements and footnotes for 2019 and 2018 to conform to the classifications presented in 2020. Such reclassifications had no impact on net income or stockholders’ equity.
Adoption of New Accounting Standards in 2020 and 2021	Adoption of New Accounting Standards in 2021 ASU No. 2016-13, “Financial Instruments – Credit Losses (Topic 326): Assets Measured at Amortized Cost.” (modified by ASU 2018-19, ASU 2019-04 and ASU 2019-05). ASU 2016-13 requires a financial asset (or a group of financial assets) measured at amortized cost basis to be presented at the net amount expected to be collected. The amendments in this update replace the incurred loss impairment methodology in current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates and affects loans, debt securities, trade receivables, off-balance-sheet credit exposures, reinsurance receivables, and any other financial assets not excluded from the scope that have the contractual right to receive cash. For SEC filers that are not smaller reporting companies, the amendments in this update are effective for the fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. In December 2018, the OCC, the Board of Governors of the Federal Reserve System, and the FDIC approved a final rule to address changes to credit loss accounting under GAAP, including banking organizations’ implementation of ASU No. 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“CECL”). Under the CARES Act, the effective date for the implementation of ASU No. 2016-13 was delayed until the earlier of the end of the health crises caused by the COVID-19 Pandemic or December 31, 2020. The Economic Aid Act then further delayed implementation until the earlier of the end of the health crises caused by the COVID-19 Pandemic or December 31, 2022. The Company is adopting Topic 326, as of January 1, 2021. While the Company has not finalized the impact of implementing CECL, the Company expects to recognize a one-time cumulative effect adjustment to the allowance and beginning retained earnings, net of tax, upon adoption. The future impact of CECL on the Company’s allowance for credit losses and provision expense subsequent to the initial adoption will depend on changes in the loan portfolio, economic conditions and refinements to key assumptions including forecasting and qualitative factors. The Company measured its allowance under its current incurred loan loss model as of December 31, 2020.

Schedule of Effective Income Tax Rate Reconciliation [Table Text Block]	On July 1, 2018 New Jersey Governor Phil Murphy signed Assembly Bill 4202 (“the Bill”) into law. The legislation imposes a temporary surtax on corporations earning New Jersey allocated income in excess of $1 million of 2.5% for tax years beginning on or after January 1, 2018 through December 31, 2019, and of 1.5% for tax years beginning on or after January 1, 2020 through December 31, 2021. However, in 2020, this surtax was extended through December 31, 2023, at the 2.5% level. The legislation also requires combined filing for members of an affiliated group for tax years beginning on or after January 1, 2019, changing New Jersey’s current status as a separate return state, and limits the deductibility of dividends received.

Retirement Benefits [Abstract]
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 with Legacy ConnectOne. 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.
