(the “Parent Corporation”) is incorporated under the laws of the State of New Jersey and is a registered bank holding company under the Bank Holding Company Act of 1956, 1, The Bank is a community-based, full-service New Jersey-chartered commercial bank that was founded in 2005. 301 24 Basis of Presentation and Principals of Consolidation The consolidated financial statements have been prepared in conformity with U.S. generally accepted accounting principles. 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. Segments FASB ASC 28, one not one 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 Recent events impacting the financial services industry, including the failures of Silicon Valley Bank, Signature Bank and First Republic Bank, have resulted in increased volatility and reduced valuations of equity and other securities of banks in the capital markets. In addition, the Federal Reserve, in order to combat inflation, has employed quantitative tightening in order to reduce the size of its balance sheet, resulting in increased competition and costs for bank deposits and an increased risk of an economic recession. These recent events have, and could continue to, increase competition for deposits and adversely impact the market price and volatility of the Company’s common stock. The United States economy is currently experiencing a level of price inflation not 1970’s 1980’s. may Cash and Cash Equivalents Cash and cash equivalents include cash, deposits with other financial institutions with maturities of less than 90 Investment Securities Effective January 1, 2021, 320 10 05. 1 2 3 not two may 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 available-for-sale are carried at fair value, with unrealized holding gains and losses reported in comprehensive income, net of tax. Interest income includes amortization of purchase premiums or discounts. Premiums and discounts on securities are generally amortized using the level-yield method without estimating prepayments, except for mortgage-backed securities, where prepayment rates are estimated. Premiums on callable investment securities are amortized to their earliest call date. Gains and losses on sales of securities are recorded on the trade date and determined using the specific identification method. For available-for-sale investment securities which are in an unrealized loss position, the Company will first not, not not zero no Equity Securities The Company’s investments in equity securities are recorded at fair value, with unrealized gains and losses included in earnings. Loans Held-for-Sale Residential mortgage loans, originated and intended for sale in the secondary market, are carried at the lower of aggregate cost or estimated fair value as determined by outstanding commitments from investors. For these loans originated and intended for sale, gains and losses on loan sales (sale proceeds minus carrying value) are recorded in other income and direct loan origination costs and fees are deferred at origination of the loan and are recognized in other income upon sale of the loan. Other loans held-for-sale are carried at the lower of aggregate cost or estimated fair value. Fair value on these loans is determined based on the terms of the loan, such as interest rate, maturity date, and 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 credit 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 certain cases, loans are placed on nonaccrual or charged-off at an earlier date if collection of principal or interest is considered doubtful. Nonaccrual loans include both smaller balance homogeneous loans that are collectively evaluated for credit losses and loans individually analyzed for credit losses. All interest accrued but not The policy of the Company is to grant commercial, residential and consumer loans to residents and businesses within the market-areas served by its offices in New Jersey, New York and Florida. 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 credit 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 Credit Losses The allowance for credit losses is an estimate of current expected credit losses considering available information relevant to assessing collectability of cash flows over the contractual term of the financial assets necessary to cover lifetime expected credit losses inherent in financial assets at the balance sheet date. The measurement of expected credit losses is applicable to loans receivable and investment securities measured at amortized cost. It also applies to off-balance sheet credit exposures such as loan commitments and unused lines of credit. Loan losses are charged against the allowance for credit losses when the Company believes the uncollectibility of a loan balance is confirmed. Subsequent recoveries, if any, are credited to the allowance for credit losses. The allowance is established through a provision for credit losses that is charged against income. The methodology for determining the allowance for credit losses is considered a critical accounting policy by management because of the high degree of judgment involved, the subjectivity of the assumptions used, and the potential for changes in the forecasted economic environment that could result in changes to the amount of the recorded allowance for credit losses. The expected credit loss for unfunded loan commitments is reported on the consolidated statement of financial condition in other liabilities. For financial assets, the allowance for credit losses is a valuation account that is deducted from, or added to, the amortized cost basis of the financial assets to present the net amount expected to be collected on the financial assets. The Company's methodology to estimate the allowance for credit losses has two not Information relevant to establishing an estimate of current expected credit losses includes historical credit loss experience on financial assets with similar risk characteristics, current conditions, and reasonable and supportable forecasts that affect the collectability of the remaining cash flows over the contractual term of the financial assets. The Company reports in net income (as a credit loss expense) the amount necessary to adjust the allowance for credit losses and liabilities for credit losses on off-balance-sheet credit exposures for the current estimate of expected credit losses. Expected credit losses of financial assets are measured on a collective (pool) basis when similar risk characteristic(s) exist. If the Company determines that a financial asset does not may one not 1 2 3 4 5 6 7 8 9 10 The Company’s quantitative analysis also considers relevant available information from internal and external sources related to past events and current conditions, as well as the incorporation of reasonable and supportable forecasts. The Company evaluates a variety of factors including third Included in the allowance for credit losses are qualitative reserves to cover losses that are expected but, in the Company’s assessment, may not may The Bank evaluates individual instruments for expected credit losses when those instruments do not Nonaccrual loans that are $250,000 or higher and all purchased credit-deteriorated ("PCD") loans are individually analyzed. For loans designated as nonaccrual with balances of less than $250,000, these loans are collectively evaluated, and, accordingly, are not not For collateral dependent loans, when it is determined that a foreclosure is probable, the allowance for credit losses is determined on a loan level basis using the fair value of the collateral as of the reporting date, less estimated disposition costs (“net fair value”), which will ensure that the credit loss is not not Purchased Credit-Deteriorated Loans Loans acquired in a business combination that have experienced a more-than-significant deterioration in credit quality since origination are considered PCD loans. The Company evaluates acquired loans for deterioration in credit quality based on any of, but not 1 2 3 4 5 no 2016 13 PCD loans that met the criteria for nonaccrual may may no may Derivatives 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 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 no no no When hedge accounting is discontinued, subsequent changes in fair value of the derivative are recorded as noninterest income. When a cash flow hedge is discontinued but the hedged cash flows or forecasted transactions are still expected to occur, gains or losses that were accumulated in other comprehensive income are amortized into earnings over the same periods which the hedged transactions will affect earnings. Restricted Stock The Bank is a member of the Federal Home Loan Bank (“FHLB”) of New York. Members are required to own a certain amount of stock based on the level of borrowings and other factors and may 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 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 not 12 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, September 30, 2007 1974. The Company accounts for its defined benefit pension plan in accordance with FASB ASC 715 30. 715 30 715 30 The Company maintains a 401 401 Stock-Based Compensation Stock compensation accounting guidance (FASB ASC 718, 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.

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 Fair Value of Financial Instruments The 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” 50% not not” no Advertising Costs The Company recognizes its marketing and advertising costs as incurred.

This data forms the basis for the construction of a best-estimate range of real investment returns for each asset class. A weighted average real-return range is computed reflecting the plan’s expected asset mix, and that range, when combined with an expected inflation range, produces an overall best-estimate expected return range. Specific factors such as the plan’s investment policy, reinvestment risk and investment volatility are taken into consideration during the construction of the best estimate real return range, as well as in the selection of the final return assumption from within the range. Plan Assets The general investment policy of the Pension Trust is for the fund to experience growth in assets that will allow the market value to exceed the value of benefit obligations over time.

Actual results could differ significantly from those estimates.
Risks and Uncertainties [Policy Text Block]	Risks and Uncertainties Recent events impacting the financial services industry, including the failures of Silicon Valley Bank, Signature Bank and First Republic Bank, have resulted in increased volatility and reduced valuations of equity and other securities of banks in the capital markets. In addition, the Federal Reserve, in order to combat inflation, has employed quantitative tightening in order to reduce the size of its balance sheet, resulting in increased competition and costs for bank deposits and an increased risk of an economic recession. These recent events have, and could continue to, increase competition for deposits and adversely impact the market price and volatility of the Company’s common stock. The United States economy is currently experiencing a level of price inflation not 1970’s 1980’s. may

Financing Receivable, Held-for-Sale [Policy Text Block]	Loans Held-for-Sale Residential mortgage loans, originated and intended for sale in the secondary market, are carried at the lower of aggregate cost or estimated fair value as determined by outstanding commitments from investors. For these loans originated and intended for sale, gains and losses on loan sales (sale proceeds minus carrying value) are recorded in other income and direct loan origination costs and fees are deferred at origination of the loan and are recognized in other income upon sale of the loan. Other loans held-for-sale are carried at the lower of aggregate cost or estimated fair value. Fair value on these loans is determined based on the terms of the loan, such as interest rate, maturity date, and reset term, as well as sales of similar assets.
Policy Loans Receivable, Policy [Policy Text Block]	Loans Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are reported at the principal balance outstanding, net of deferred loan fees and costs, purchase premium and discounts and an allowance for credit 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 certain cases, loans are placed on nonaccrual or charged-off at an earlier date if collection of principal or interest is considered doubtful. Nonaccrual loans include both smaller balance homogeneous loans that are collectively evaluated for credit losses and loans individually analyzed for credit losses. All interest accrued but not The policy of the Company is to grant commercial, residential and consumer loans to residents and businesses within the market-areas served by its offices in New Jersey, New York and Florida. 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 credit 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.
Loans and Leases Receivable, Allowance for Loan Losses Policy [Policy Text Block]	Allowance for Credit Losses The allowance for credit losses is an estimate of current expected credit losses considering available information relevant to assessing collectability of cash flows over the contractual term of the financial assets necessary to cover lifetime expected credit losses inherent in financial assets at the balance sheet date. The measurement of expected credit losses is applicable to loans receivable and investment securities measured at amortized cost. It also applies to off-balance sheet credit exposures such as loan commitments and unused lines of credit. Loan losses are charged against the allowance for credit losses when the Company believes the uncollectibility of a loan balance is confirmed. Subsequent recoveries, if any, are credited to the allowance for credit losses. The allowance is established through a provision for credit losses that is charged against income. The methodology for determining the allowance for credit losses is considered a critical accounting policy by management because of the high degree of judgment involved, the subjectivity of the assumptions used, and the potential for changes in the forecasted economic environment that could result in changes to the amount of the recorded allowance for credit losses. The expected credit loss for unfunded loan commitments is reported on the consolidated statement of financial condition in other liabilities. For financial assets, the allowance for credit losses is a valuation account that is deducted from, or added to, the amortized cost basis of the financial assets to present the net amount expected to be collected on the financial assets. The Company's methodology to estimate the allowance for credit losses has two not Information relevant to establishing an estimate of current expected credit losses includes historical credit loss experience on financial assets with similar risk characteristics, current conditions, and reasonable and supportable forecasts that affect the collectability of the remaining cash flows over the contractual term of the financial assets. The Company reports in net income (as a credit loss expense) the amount necessary to adjust the allowance for credit losses and liabilities for credit losses on off-balance-sheet credit exposures for the current estimate of expected credit losses. Expected credit losses of financial assets are measured on a collective (pool) basis when similar risk characteristic(s) exist.

Derivatives, Policy [Policy Text Block]	Derivatives 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 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 no no no When hedge accounting is discontinued, subsequent changes in fair value of the derivative are recorded as noninterest income.
