Summary of Significant Accounting Policies

Accounting Policies [Abstract]  
Summary of Significant Accounting Policies Summary of Significant Accounting Policies
 
The following significant accounting and reporting policies of Northfield Bancorp, Inc. and subsidiaries (collectively, the “Company”) conform to U.S. generally accepted accounting principles (“U.S. GAAP”) and are used in preparing and presenting these consolidated financial statements.
 
(a)    Basis of Presentation
 
The consolidated financial statements are comprised of the accounts of Northfield Bancorp, Inc. and its wholly owned subsidiaries, Northfield Investment, Inc. and Northfield Bank (the “Bank”), and the Bank’s wholly-owned subsidiaries, NSB Services Corp. and NSB Realty Trust.  All significant intercompany accounts and transactions have been eliminated in consolidation.
 
In preparing the consolidated financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the balance sheets and revenues and expenses during the reporting periods. Actual results may differ significantly from those estimates and assumptions. A material estimate that is particularly susceptible to significant change in the near term is the allowance for credit losses. In connection with the determination of this allowance, management generally obtains independent appraisals for significant properties. In addition, judgments related to the amount and timing of expected cash flows from purchased credit-deteriorated (“PCD”) loans, goodwill, securities valuation and impairment, and deferred income taxes, involve a higher degree of complexity and subjectivity and require estimates and assumptions about uncertain matters. Actual results may differ from the estimates and assumptions. 
 
(b)    Recent Accounting Pronouncements Adopted

Accounting Standards Update (“ASU”) No. 2023-07. In November 2023, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) ASU No. 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures”. The amendments in this ASU require improved reportable segment information on an annual and interim basis, primarily through enhanced disclosures about significant segment expenses and information used to assess segment performance by the Company's chief operating decision maker (“CODM”). The Company's CODM is its President and Chief Executive Officer. This update is effective for financial statements issued for fiscal years beginning after December 15, 2023, and interim periods for fiscal years beginning after December 15, 2024. ASU 2023-07 should be applied retrospectively to all prior periods presented in the financial statements. The adoption of ASU 2023-07 did not have a material effect on the Company's financial position, results of operations or financial statement disclosures as the Company operates one operating segment. See Note 23 to the consolidated financial statements.

Accounting Standards Update (“ASU”) No. 2020-04. In March 2020, the FASB issued ASU No. 2020-04, “Reference Rate Reform (“Topic 848”): Facilitation of the Effects of Reference Rate Reform on Financial Reporting” (“ASU 2020-04”), which provides temporary optional guidance to ease the potential burden in accounting for reference rate reform. The ASU provides optional expedients and exceptions for applying generally accepted accounting principles to contract modifications and hedging relationships, subject to meeting certain criteria, that reference the London Inter-Bank Offered Rate (“LIBOR”) or another reference rate expected to be discontinued. It is intended to help stakeholders during the global market-wide reference rate transition period. The guidance was effective for all entities as of March 12, 2020 through December 31, 2022. However, in December 2022, the FASB issued ASU 2022-06, deferring the sunset date to December 31, 2024. The Company has reviewed all of its LIBOR-based products and all products have been adjusted to another index or are scheduled to be adjusted at their next repricing, as LIBOR ceased to be published after June 30, 2023. The adoption of this ASU did not have a material impact on the Company's consolidated financial statements.
ASU No. 2022-02. In March 2022, the FASB issued ASU No. 2022-02, “Financial Instruments - Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures” (“ASU 2022-02”). The amendments in this ASU were issued to (1) eliminate accounting guidance for Troubled Debt Restructurings (“TDRs”) by creditors, while enhancing disclosure requirements for certain loan refinancings and restructurings by creditors when a borrower is experiencing financial difficulty; (2) require disclosures of current period gross write-offs by year of origination for financing receivables and net investments in leases. Under ASU 2022-02, the Company assesses all loan modifications to determine whether one is granted to a borrower experiencing financial difficulty, regardless of whether the modified loan terms include a concession. Modifications granted to borrowers experiencing financial difficulty may be in the form of an interest rate reduction, an other-than-insignificant payment delay, a term extension, principal forgiveness or a combination thereof. The Company adopted ASU 2022-02 on a prospective basis on January 1, 2023. The adoption of this update did not have a material effect on the Company’s consolidated financial statements. Additional disclosures are included in Note 5 to the consolidated financial statements.

(c)    Business
 
The Company, through its principal subsidiary, the Bank, provides a full range of banking services primarily to individuals and corporate customers in Richmond and Kings counties in New York, and Hunterdon, Mercer, Union and Middlesex counties in New Jersey. The Company is subject to competition from other financial institutions and to the regulations of certain federal and state agencies, and undergoes periodic examinations by those regulatory authorities.

(d)    Cash Equivalents
 
Cash equivalents consist of cash on hand, due from banks, and interest-bearing deposits in other financial institutions with an original term of three months or less. 
 
(e)    Securities
 
Securities are classified at the time of purchase, based on management’s intention, as debt securities held-to-maturity, debt securities available-for-sale, trading account securities or equity securities. Debt securities held-to-maturity are those that management has the positive intent and ability to hold until maturity. Debt securities held-to-maturity are carried at amortized cost, adjusted for amortization of premiums and accretion of discounts using the level-yield method over the contractual term of the securities, adjusted for actual prepayments. Debt securities available-for-sale represents all securities not classified as either held-to-maturity, trading, or equity. Debt securities available-for-sale are carried at estimated fair value with unrealized holding gains and losses (net of related tax effects) on such securities excluded from earnings, but included as a separate component of stockholders’ equity, titled “Accumulated other comprehensive income (loss).” The cost of securities sold is determined using the specific-identification method. Security transactions are recorded on a trade-date basis.

For securities available-for-sale, the Company determines if impairment is related to credit loss or non-credit loss. In making the assessment of whether a loss is from credit or other factors, management considers the extent to which fair value is less than amortized cost, any changes to the rating of the security by a rating agency and adverse conditions related to the security, among other factors. If this assessment indicates that a credit loss exists, the present value of cash flows expected to be collected from the security are compared to the amortized cost basis of the security. If the present value of cash flows is less than the amortized cost basis, a credit loss exists and an allowance is created, limited by the amount that the fair value is less than the amortized cost basis. Subsequent activity related to the credit loss component in the form of write-offs or recoveries is recognized as part of the allowance for credit losses on securities available-for-sale.

Management measures expected credit losses on held-to-maturity debt securities on a collective basis by major security type. All of the held-to-maturity securities in the Company's portfolio are issued by U.S. government agencies and are either explicitly or implicitly guaranteed by the U.S Government and therefore the expectation of nonpayment is zero. Therefore, the Company is not required to estimate an allowance for credit losses related to these securities.

The estimated fair value of debt securities, including mortgage-backed securities and corporate debt obligations is furnished by an independent third-party pricing service. The third-party pricing service primarily utilizes pricing models and methodologies that incorporate observable market inputs, including among other things, benchmark yields, reported trades, and projected prepayment and default rates. Management reviews the data and assumptions used in pricing the securities by its third-party provider for reasonableness.
The Company has made the accounting policy election to exclude accrued interest receivable on securities from the estimate of credit losses. Accrued interest receivable totaled $3.1 million and $2.4 million at December 31, 2024 and 2023, respectively, and is reported in accrued interest receivable on the consolidated balance sheets.
Trading securities are securities that are bought and may be held for the purpose of selling them in the near term. Trading securities are reported at estimated fair value, using quoted prices in active markets, with unrealized holding gains and losses reported as a component of gain (loss) on securities, net in non-interest income.

Equity securities with readily determinable fair values are stated at fair value with unrealized gains and losses reported as a component of gain (loss) on securities, net in non-interest income. Equity securities without readily determinable fair values are recorded at net asset value less any impairment, if any.
 
(f)    Loans and Allowance for Credit Losses
 
The accounting and reporting for PCD loans and loans classified as held-for-sale differs substantially from those loans classified by the Company as held-for-investment. For purposes of reporting, discussion and analysis, management has classified its loan portfolio into three categories: (1) loans originated by the Company and held-for-sale, which are carried at the lower of aggregate cost or estimated fair value, less costs to sell, and therefore have no associated allowance for loan losses, (2) PCD loans, which are held-for-investment, and recorded at the purchase price, including non-credit discounts, plus the allowance for credit losses at the time of acquisition, and (3) loans held-for-investment, which include originated loans carried at amortized cost, and acquired loans, with no evidence of credit deterioration, initially valued at fair value on the date of acquisition, less net charge-offs and the allowance for credit losses.
 
Net loans held-for-investment are stated at unpaid principal balance, adjusted by unamortized premiums and unearned discounts, deferred origination fees and certain direct origination costs, and the allowance for credit losses. Interest income on loans is accrued and credited to income as earned. Net loan origination fees/costs are deferred and accreted/amortized to interest income over the loan’s contractual life using the level-yield method, adjusted for actual prepayments. Generally, loans held-for-sale are designated at time of origination and generally consist of newly originated fixed-rate residential loans and are recorded at the lower of aggregate cost or estimated fair value in the aggregate. Transfers of loans from held-for-investment to held-for-sale are infrequent and occur at fair value less costs to sell, with any charge-off to allowance for credit losses. Gains are recognized on a settlement-date basis and are determined by the difference between the net sales proceeds and the carrying value of the loans, including any net deferred fees or costs.
 
Net loans held-for-investment are deemed impaired when it is probable, based on current information, that the Company will not collect all amounts due in accordance with the contractual terms of the loan agreement. The Company has defined the population of loans individually evaluated for impairment to be all non-accrual loans held-for-investment with an outstanding balance of $500,000 or greater and all loans restructured as TDRs prior to the adoption of ASU 2022-02. Loan held-for-investment are individually assessed to determine that the loan’s carrying value is not in excess of the expected future cash flows, discounted at the loan's original effective interest rate, or the fair value of the underlying collateral (less estimated costs to sell) if the loan is collateral dependent. Impairments, if any, are recognized through a charge to the allowance for credit losses on loans for the amount that the loan’s carrying value exceeds the discounted cash flow analysis or estimated fair value of collateral (less estimated costs to sell) if the loan is collateral dependent.  Such amounts are charged-off when considered appropriate.  
 
Allowance for Credit Losses on Loans

Under the current expected credit losses (“CECL”) methodology adopted on January 1, 2021, the Company determines the allowance for credit losses on loans based upon a consideration of its historical portfolio loss experience, current borrower-specific risk characteristics, current conditions, forecasts of future economic conditions, reversion period, prepayments, and qualitative adjustments. The allowance is measured on a collective (loan segment) basis when similar risk characteristics exist. Loans that do not share common risk characteristics are evaluated on an individual basis and are excluded from the collective evaluation. Accrued interest on loans is excluded from the calculation of the allowance for credit losses due to the Company's non-accrual policy, which results in the reversal of uncollectible accrued interest on non-accrual loans against interest income in a timely manner. Accrued interest receivable on loans held-for-investment totaled $12.5 million and $12.8 million, respectively, at December 31, 2024 and 2023 and is reported in accrued interest receivable on the consolidated balance sheets.
Allowance for Collectively Evaluated Loans Held-for-Investment. In estimating the quantitative component of the allowance on a collective basis, the Company uses a risk rating migration model which calculates an expected life of loan loss percentage for each loan by generating probability of default and loss given default metrics. These metrics are multiplied by the exposure at default, taking into consideration prepayments, to calculate the quantitative component of the allowance. The metrics are based on the migration of loans from performing to loss by credit risk rating or delinquency categories using historical life-of-loan analysis periods for each loan portfolio pool, and the severity of loss, based on the aggregate net lifetime losses incurred using the Company's own historical loss experience and comparable peer data loss history. The model's expected losses based on loss history are adjusted for qualitative adjustments to address risks that may not be adequately represented in the risk rating migration model. Among other things, these adjustments include and account for differences in: (i) changes in lending policies and procedures; (ii) changes in local, regional, national, and international economic and business conditions and developments that affect the collectability of our portfolio, including the condition of various market segments; (iii) changes in the experience, ability and depth of lending management and other relevant staff; (iv) changes in the quality of our loan review system; (v) the existence and effect of any concentrations of credit, and changes in the level of such concentrations; and (vi) the effect of other external factors such as competition and legal and regulatory requirements on the level of estimated credit losses in our existing portfolio.

The Company utilizes a two-year reasonable and supportable forecast period after which estimated losses revert to historical loss experience immediately for the remaining life of the loan. In establishing its estimate of expected credit losses, the Company utilizes five externally-sourced forward-looking economic scenarios developed by Moody's Analytics (“Moody's”) so as to incorporate uncertainties related to the economic environment. These scenarios, which range from more benign to more severe economic outlooks, include a ‘most likely outcome’ (the “Baseline” scenario) and four less likely scenarios referred to as the “Upside” and “Downside” scenarios. Each scenario is assigned a weighting with a majority of the weighting placed on the Baseline scenario and lower weights placed on both the Upside and Downside scenarios. The weighting assigned by management is based on the economic outlook and available information at the reporting date. The model projects economic variables under each scenario based on detailed statistical analyses. The Company has identified and selected key variables that most closely correlated to its historical credit performance, which include: Gross domestic product, unemployment, and three collateral indices: the Commercial Property Price Index, the Commercial Property Price Apartment Index and the Case-Shiller Home Price Index.

Allowance for Individually Evaluated Loans. The Company measures specific reserves for individual loans that do not share common risk characteristics with other loans, consisting of all TDRs (prior to the adoption of ASU 2022-02) and non-accrual loans with an outstanding balance of $500,000 or greater. Loans individually evaluated for impairment are assessed to determine that the loan’s carrying value is not in excess of the estimated fair value of the collateral less cost to sell, if the loan is collateral-dependent, or the present value of the expected future cash flows, if the loan is not collateral-dependent. Management performs an evaluation of each individually evaluated loan and generally obtains updated appraisals as part of the evaluation. In addition, management adjusts estimated fair values down to appropriately consider recent market conditions, our willingness to accept a lower sales price to effect a quick sale, and costs to dispose of any supporting collateral. Determining the estimated fair value of underlying collateral (and related costs to sell) can be difficult in illiquid real estate markets and is subject to significant assumptions and estimates. Management employs an independent third-party management firm that specializes in appraisal preparation and review to ascertain the reasonableness of updated appraisals. Projecting the expected cash flows for historical TDRs (prior to adoption of ASU 2022-02) which are not collateral-dependent is inherently subjective and requires, among other things, an evaluation of the borrower’s current and projected financial condition. Individually evaluated loans that have no impairment losses are not considered for collective allowances described above. Upon adoption of ASU 2022-02, the Company no longer establishes a specific reserve for loan modifications to borrowers experiencing financial difficulty. Instead, these modified loans are included in their respective pool and a historical loss rate is applied to the current loan balance to arrive at the quantitative and qualitative baseline portion of the allowance for credit losses.
PCD Loans. Loans classified as PCD loans are acquired loans where there is evidence of more than insignificant credit deterioration since their origination. We consider various factors in connection with the determination of the amount of the allowance for these loans, including past due or non-accrual status, credit risk rating declines, and any write downs recorded based on the collectability of the asset, among other factors. Under the CECL methodology, the Company elected to maintain pools of loans that were previously accounted for under Accounting Standards Codification (“ASC”) Subtopic 310-30, “Loans and Debt Securities Acquired with Deteriorated Credit Quality, and will continue to account for these pools as a unit of account. Loans are only removed from existing pools if they are written off, paid off, or sold. Under CECL, the allowance for credit losses was determined for each pool and added to the pool's carrying amount to establish a new amortized cost basis. The difference between the unpaid principal balance of the pool and the new amortized cost basis is the noncredit premium or discount which will be amortized into interest income over the remaining life of the pool. Subsequent increases or decreases in the allowance for credit losses related to PCD loans is recorded as provision expense.
Off-Balance Sheet. The Company also maintains a reserve for estimated losses on off-balance sheet credit risks related to loan commitments and stand-by letters of credit. The reserve for off-balance sheet exposures is determined using the CECL reserve factor in the related funded loan segment, adjusted for an average historical funding rate. The allowance for credit losses for off-balance sheet credit exposures is recorded in other liabilities on the consolidated balance sheets and the corresponding provision is included in other non-interest expense.
 
While management uses available information to estimate credit losses on loans, future additions may be necessary based on changes in conditions, including changes in economic conditions and forecasts, particularly in Richmond and Kings counties in New York, and Hunterdon, Mercer, Union and Middlesex counties in New Jersey and, to a lesser extent, eastern Pennsylvania. Accordingly, as with most financial institutions in the market area, the ultimate collectability of a substantial portion of the Company’s loan portfolio is susceptible to changes in conditions in the Company’s marketplace. In addition, future changes in laws and regulations could make it more difficult for the Company to collect all contractual amounts due on its loans.
 
In addition, various regulatory agencies, as an integral part of their examination process, periodically review the Company’s allowance for credit losses. Such agencies may require the Company to recognize additions to the allowance based on their judgments about information available to them at the time of their examination.
 
Prior to the adoption of ASU 2022-02, the Company classified certain loans as TDRs, which are loans where terms have been modified because of deterioration in the financial condition of the borrower. Modifications could include extension of the repayment terms of the loan, reduced interest rates, or forgiveness of accrued interest and/or principal. Once an obligation has been restructured because of such credit problems, it continues to be considered restructured until paid in full or, if the obligation yields a market rate (a rate equal to the rate the Company was willing to accept at the time of the restructuring for a new loan with comparable risk), until the year subsequent to the year in which the restructuring takes place, provided the borrower has performed under the modified terms for a consecutive six-month period. The Company records an impairment charge equal to the difference between the present value of estimated future cash flows under the restructured terms discounted at the original loan’s effective interest rate, or the underlying collateral value, less estimated costs to sell, if the loan is collateral dependent. Changes in present values attributable to the passage of time are recorded as a component of the provision for credit losses. Since the adoption of ASU 2022-02, the Company has ceased to recognize or measure new TDRs but those existing at December 31, 2022 remain until settled.
A loan is considered past due when it is not paid in accordance with its contractual terms. The accrual of income on loans, including impaired loans held-for-investment, and other loans in the process of foreclosure, is generally discontinued when a loan becomes 90 days or more delinquent, or sooner when certain factors indicate that the ultimate collection of principal and interest is in doubt. Loans on which the accrual of income has been discontinued are designated as non-accrual loans. All previously accrued interest is reversed against interest income, and income is recognized subsequently only in the period that cash is received, provided no principal payments are due and the remaining principal balance outstanding is deemed collectible. A non-accrual loan is not returned to accrual status until both principal and interest payments are brought current and factors indicating doubtful collection no longer exist, including performance by the borrower under the loan terms for a consecutive six-month period.

(g)        Federal Home Loan Bank (“FHLB”) Stock
 
The Bank, as a member of the FHLB of New York (“FHLBNY”), is required to hold shares of capital stock in the FHLB as a condition to both becoming a member and engaging in certain transactions with the FHLB. The minimum investment requirement is determined by a “membership” investment component and an “activity-based” investment component. The membership investment component is the greater of 0.125% of the Bank’s mortgage-related assets, as defined by the FHLB, or $1,000. The activity-based investment component is equal to 4.5% of the Bank’s outstanding advances with the FHLB. The activity-based investment component also considers other transactions, including assets originated for or sold to the FHLB, and delivery commitments issued by the FHLB. The Company currently does not enter into these other types of transactions with the FHLB. 
    
On at least a quarterly basis, we perform an impairment analysis of FHLB stock in which we evaluate, among other things, (i) its earnings performance, including the significance of any decline in net assets of the FHLB as compared to the regulatory capital amount of the FHLB, (ii) the commitment by the FHLB to continue dividend payments, and (iii) the liquidity position of the FHLB. We did not consider our investment in FHLB stock to be impaired at December 31, 2024 or 2023.
 
(h)    Operating Leases
During the normal course of business, the Company enters into agreements, and at inception it determines if a particular agreement is a lease. The Company's operating lease agreements relate primarily to its corporate offices and bank branch offices. The agreements are recorded as operating lease right-of-use assets and operating lease liabilities on the consolidated balance sheets. Operating lease right-of-use assets and operating lease liabilities are recognized at the commencement date based on the present value of lease payments over the lease term, and represent the right to use an underlying asset for the lease term and the obligation to make lease payments arising from the lease. As the Company's leases do not provide an implicit rate, the Company uses its incremental borrowing rate in determining the present value of lease payments. The Company's lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the term of the lease.

(i)    Premises and Equipment, Net
 
Premises and equipment, including leasehold improvements, are carried at cost, less accumulated depreciation and amortization. Depreciation and amortization of premises and equipment, including capital leases, are computed on a straight-line basis over the estimated useful lives of the related assets.  The estimated useful lives of significant classes of assets are generally as follows: buildings - forty years; furniture and equipment - five to seven years; and purchased computer software - three years. Leasehold improvements are amortized over the shorter of the term of the related lease or the estimated useful lives of the improvements. Major improvements are capitalized, while repairs and maintenance costs are charged to operations as incurred. Upon retirement or sale, any gain or loss is credited or charged to operations.
 
(j)    Bank-Owned Life Insurance
 
The Company has purchased bank-owned life insurance contracts to help fund its obligations for certain employee benefit costs. The Company’s investment in such insurance contracts has been reported on the consolidated balance sheets at their cash surrender values. Changes in cash surrender values and death benefit proceeds received in excess of the related cash surrender values are recorded as non-interest income.
 
(k)    Goodwill
 
Intangible assets resulting from acquisitions under the purchase method of accounting consist of goodwill and other intangible assets.

Goodwill is allocated to Northfield’s reporting unit at the date goodwill is actually recorded. As of December 31, 2024, the carrying value of goodwill totaled $41.0 million. The Company qualitatively assessed the current economic environment, including macroeconomic conditions, industry and market conditions and overall financial performance of the Company, among others. After consideration of the results of the interim and annual 2024 impairment tests and the results for the year ended December 31, 2024, the Company determined that it was more-likely-than-not that the fair value of its reporting unit was above its book value as of December 31, 2024, which did not indicate impairment for our reporting unit, nor was our reporting unit at risk. The Company will test goodwill for impairment between annual test dates if an event occurs or circumstances change that would indicate the fair value of the reporting unit is below its carrying amount. The Company completed its annual impairment test as of December 31, 2024.

(l)    Income Taxes
 
Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to temporary differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply in the year in which those temporary differences are expected to be recovered or settled.  When applicable, deferred tax assets are reduced by a valuation allowance for any portions determined not likely to be realized. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date.
 
    Income tax benefits are recognized and measured based upon a two-step model: 1) a tax position must be more-likely-than-not to be sustained based solely on its technical merits in order to be recognized, and 2) the benefit is measured as the largest dollar amount of that position that is more-likely-than-not to be sustained upon settlement. The difference between the benefit recognized and the tax benefit claimed on a tax return is referred to as an unrecognized tax benefit. The Company records income tax-related interest and penalties, if applicable, within income tax expense.
 
(m)    Impairment of Long-Lived Assets
 
Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to future undiscounted (and without interest) net cash flows expected to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the fair value of the assets. Assets to be disposed of are reported at the lower of the carrying amount or fair value, less estimated costs to sell.
 
(n)    Securities Sold Under Agreements to Repurchase and Other Borrowings
 
The Company enters into sales of securities under agreements to repurchase (Repurchase Agreements) and collateral pledge agreements (Pledge Agreements) with selected dealers and banks. Such agreements are accounted for as secured financing transactions since the Company maintains effective control over the transferred or pledged securities and the transfer meets the other accounting and recognition criteria as required by the transfer and servicing topic of the FASB Accounting Standards. Obligations under these agreements are reflected as a liability on the consolidated balance sheets. Securities underlying the agreements are maintained at selected dealers and banks as collateral for each transaction executed and may be sold or pledged by the counterparty. Collateral underlying Repurchase Agreements that permit the counterparty to sell or pledge the underlying collateral is disclosed on the consolidated balance sheets as “encumbered.” The Company retains the right under all Repurchase Agreements and Pledge Agreements to substitute acceptable collateral throughout the terms of the agreement. 
 
(o)    Comprehensive Income (Loss)
 
Comprehensive income (loss) includes net income and the change in unrealized holding gains and losses on debt securities available-for-sale, change in actuarial gains and losses on other post-retirement benefits, and change in service cost on other postretirement benefits, net of taxes. Comprehensive income (loss) and its components is presented on the consolidated statements of comprehensive income.
 
(p)   Benefits
 
The Company sponsors a defined postretirement benefit plan that provides for medical and life insurance coverage to a limited number of retirees, as well as life insurance to all qualifying employees of the Company. The estimated cost of postretirement benefits earned is accrued during an individual’s estimated service period to the Company. The Company recognizes on its balance sheet the over-funded or under-funded status of a defined benefit postretirement plan measured as the difference between the fair value of plan assets and the benefit obligation at the end of our calendar year. The actuarial gains and losses and the prior service costs and credits that arise during the period are recognized as a component of other comprehensive income (loss), net of tax.    
 
Funds borrowed by the Employee Stock Ownership Plan (the “ESOP”) from the Company to purchase the Company’s common stock are being repaid from the Bank’s contributions over a period of up to 30 years. The Company’s common stock not yet allocated to participants is recorded as a reduction of stockholders’ equity at cost. The Company records compensation expense related to the ESOP at an amount equal to the shares committed to be released by the ESOP multiplied by the average fair value of our common stock during the reporting period.
 
The Company recognizes the grant-date fair value of stock-based awards issued to participants' as compensation cost on the consolidated statements of comprehensive income. The fair value of common stock awards is based on the closing price of our common stock as reported on the NASDAQ Stock Market on the grant date. The expense related to stock options is based on the estimated fair value of the options at the date of the grant using the Black-Scholes pricing model. The awards are fixed in nature and compensation cost related to stock-based awards is recognized on a straight-line basis over the requisite service periods. The Company accounts for forfeitures as they occur.
 
The Bank has a 401(k) plan covering substantially all employees.  Contributions to the plan are expensed as incurred. 
(q)    Segment Reporting
 
As a community-focused financial institution, substantially all of the Company’s operations involve the delivery of loan and deposit products to customers. Management makes operating decisions and assesses performance based on an ongoing review of these community banking operations, which constitute the Company’s only operating segment for financial reporting purposes. 

(r)    Net Income per Common Share
 
Net income per common share-basic is computed by dividing the net income available to common stockholders by the weighted average number of common shares outstanding, excluding unallocated ESOP shares and unearned common stock award shares. The weighted average common shares outstanding includes the average number of shares of common stock outstanding, including shares allocated or committed to be released ESOP shares. Net income per common share-diluted is computed using the same method as basic earnings per share, but reflects the potential dilution that could occur if stock options and unvested shares of restricted stock were exercised and converted into common stock.

When applying the treasury stock method we add the assumed proceeds from option exercises and the average unamortized compensation costs related to unvested shares of restricted stock and stock options. We then divided this sum by our average stock price for the period to calculate assumed shares repurchased. The excess of the number of shares issuable over the number of shares assumed to be repurchased is added to basic weighted average common shares to calculate diluted earnings per share.

At December 31, 2024, 2023, and 2022, there were 61,290, 77,772, and 203,997 dilutive shares outstanding, respectively.    

(s)    Other Real Estate Owned
 
Assets acquired through loan foreclosure, or deed-in-lieu of, are held for sale and are initially recorded at estimated fair value, less estimated selling costs, when acquired, thus establishing a new cost basis. Costs after acquisition are generally expensed. If the estimated fair value of the asset subsequently declines, a write-down is recorded through other non-interest expense.

(t)    Advertising Costs

Advertising costs are expensed in the period they are incurred.

(u)    Derivatives

The Company records all derivatives on the Consolidated Balance Sheets at fair value. The Company has interest rate derivatives resulting from a service provided to certain qualified borrowers in a loan-related transaction and, therefore, are not used to manage interest rate risk in the Company’s assets or liabilities. As such, all changes in fair value of the Company’s interest rate derivatives are recognized directly in earnings. The fair value of the Company's derivatives is determined using discounted cash flow analysis using observable market-based inputs, which are considered Level 2 inputs.

Contractual maturities for mortgage-backed securities are not included above, as expected maturities on mortgage-backed securities may differ from contractual maturities as borrowers may have the right to call or prepay obligations with or without penalties.
 
Certain securities available-for-sale are pledged or encumbered to secure borrowings under Pledge Agreements and Repurchase Agreements and for other purposes required by law. At December 31, 2024, and December 31, 2023, the fair value of debt securities available-for-sale that were pledged to secure borrowings and deposits was $420.4 million and $272.9 million, respectively. See Note 9 - “Borrowings” for further discussion regarding securities pledged or encumbered for borrowings.

For the year ended December 31, 2024, the Company had no proceeds on sales of debt securities available-for-sale, with gross realized gains of $1,000 and gross realized losses of $7,000 related to calls of securities. For the year ended December 31, 2023, the Company had no proceeds of on sales of debt securities available-for-sale with gross realized gains of $22,000 and gross realized losses of $39,000 related to calls of securities. For the year ended December 31, 2022, the Company had gross proceeds of $41.5 million on sales of debt securities available-for-sale with gross realized gains of $279,000 and no gross realized losses. The Company recognized net gains of $1.7 million in each of the years ended December 31, 2024 and December 31, 2023, and net losses of $2.2 million during the year ended December 31, 2022, on its trading securities portfolio. The Company routinely sells securities when market pricing presents, in management’s assessment, an economic benefit that outweighs holding such security, and when smaller balance securities become cost prohibitive to carry.

The Company held 108 pass-through mortgage-backed securities issued or guaranteed by GSEs, 70 REMIC mortgage-backed securities issued or guaranteed by GSEs, five U.S. Government agency securities, and three corporate bonds that were in a continuous unrealized loss position of twelve months or greater at December 31, 2024. There were seven REMIC mortgage-backed securities issued or guaranteed by GSEs and six pass-through mortgage-backed securities issued or guaranteed by GSEs that were in an unrealized loss position of less than twelve months at December 31, 2024. Substantially all securities referred to above were rated investment grade at December 31, 2024. 

Available-for-sale debt securities in unrealized loss positions are evaluated for impairment related to credit losses on a quarterly basis. In performing an assessment of whether any decline in fair value is due to a credit loss, the Company considers the extent to which the fair value is less than the amortized cost, changes in credit ratings, any adverse economic conditions, as well as relevant information at the individual security level such as credit deterioration of the issuer or collateral underlying the security. In assessing the impairment, the Company compares the present value of cash flows expected to be collected with the amortized cost basis of the security. If it is determined that the decline in fair value was due to credit losses, an allowance for credit losses is recorded, limited to the amount the fair value is less than amortized cost basis. The Company did not recognize any allowance for credit losses on its available-for-sale debt securities during the years ended December 31, 2024 or 2023. The Company does not intend to sell its available-for-sale debt securities in an unrealized loss position and it is likely that it will not be required to sell the securities before their anticipated recovery.
 
The non-credit related decrease in the fair value, such as a decline due to changes in market interest rates, is recorded in other comprehensive income, net of tax. The Company also assesses its intent to sell the securities (as well as the likelihood of a near-term recovery). If the Company intends to sell an available-for-sale debt security or it is more likely than not that it will be required to sell the security before recovery of its amortized cost basis, the debt security is written down to its fair value and the write down is charged to the debt security’s fair value at the reporting date with any incremental impairment reported in earnings.

The Company has made the accounting policy election to exclude accrued interest receivable on available-for-sale securities from the estimate of credit losses. Accrued interest receivable associated with debt securities available-for-sale totaled $3.1 million and $2.4 million at December 31, 2024 and December 31, 2023, respectively, and was reported in accrued interest receivable on the consolidated balance sheets. The Company elected not to measure an allowance for credit losses on accrued interest receivable, as an allowance on possible uncollectible accrued interest is not warranted.
Equity Securities At December 31, 2024 and December 31, 2023, equity securities totaled $14.3 million and $10.6 million, respectively. Equity securities consisted of money market mutual funds, recorded at fair value of $4.3 million and $330,000, at December 31, 2024 and December 31, 2023, respectively, and an investment in a private Small Business Administration (“SBA”) Loan Fund (the "SBA Loan Fund") recorded at net asset value of $10.0 million and $10.3 million at December 31, 2024 and December 31, 2023, respectively. As the SBA Loan Fund operates as a private fund, its shares are not publicly traded and, therefore, have no readily determinable market value. The SBA Loan Fund was recorded at net asset value as a practical expedient for reporting fair value.

Contractual maturities for mortgage-backed securities are not presented, as expected maturities on mortgage-backed securities may differ from contractual maturities as borrowers may have the right to call or prepay obligations with or without penalties. There were no sales of held-to-maturity securities for the years ended December 31, 2024, 2023 or 2022.
At December 31, 2024, and December 31, 2023, debt securities held-to-maturity with a carrying value of $9.1 million and $9.7 million, respectively, were pledged to secure repurchase agreements and deposits.

The Company held nine pass-through mortgage-backed debt securities held-to-maturity issued or guaranteed by GSEs that were in a continuous unrealized loss position of twelve months or greater at December 31, 2024.

The Company's held-to-maturity securities are residential mortgage-backed securities issued by Ginnie Mae, Freddie Mac and Fannie Mae, and it is expected that the securities will not be settled at prices less than the amortized cost bases of the securities as such securities are backed by the full faith and credit of and/or guaranteed by the U.S. Government. Accordingly, no allowance for credit losses has been recorded for these securities.

The Company has made the accounting policy election to exclude accrued interest receivable on held-to-maturity securities from the estimate of credit losses. Accrued interest receivable associated with held-to-maturity securities totaling $33,000 and $36,000, respectively, at December 31, 2024 and December 31, 2023 was reported in accrued interest receivable on the consolidated balance sheets. The Company elected not to measure an allowance for credit losses on accrued interest receivable, as an allowance on possible uncollectible accrued interest is not warranted.

The Company had loans held-for-sale of $4.9 million and $0 at December 31, 2024 and December 31, 2023, respectively.

In addition to originating loans, the Company may acquire loans through portfolio purchases or acquisitions of other companies. Purchased loans that have evidence of more than insignificant credit deterioration since origination are deemed PCD loans. For PCD loans, each loan pool is accounted for as a single asset with a single composite interest rate and an aggregate expectation of cash flows. PCD loans totaled $9.2 million at December 31, 2024, as compared to $9.9 million at December 31, 2023. The majority of the PCD loan balances were acquired as part of an FDIC-assisted transaction. At December 31, 2024, PCD loans consisted of approximately 9% one-to-four family residential loans, 25% commercial real estate loans, 55% commercial and industrial loans, and 11% in home equity loans. At December 31, 2023, PCD loans consisted of approximately 7% one-to-four family residential loans, 25% commercial real estate loans, 57% commercial and industrial loans, and 11% in home equity loans.

Credit Quality Indicators

The Company monitors the credit quality of its loan portfolio on a regular basis. Credit quality is monitored by reviewing certain credit quality indicators. Management has determined that loan-to-value (“LTV”) ratios (at period end) and internally assigned credit risk ratings by loan type are the key credit quality indicators that best measure the credit quality of the Company’s loan receivables. LTV ratios used by management in monitoring credit quality are based on current period loan balances and original appraised values at the time of origination (unless a current appraisal has been obtained as a result of the loan being deemed impaired). 
 
The Company maintains a credit risk rating system as part of the risk assessment of its loan portfolio. The Company’s lending officers are required to assign a credit risk rating to each loan in their portfolio at origination. This risk rating is reviewed periodically and adjusted if necessary. Monthly, management presents monitored assets to the Loan Committee of the Board of Directors. In addition, the Company engages a third-party independent loan reviewer that performs semi-annual reviews of a sample of loans, validating the credit risk ratings assigned to such loans. The credit risk ratings play an important role in the establishment of the provision for credit losses on loans and the allowance for credit losses for loans held-for-investment. After determining the loss factor for each portfolio segment held-for-investment, the collectively evaluated for impairment balance of the held-for-investment portfolio is multiplied by the collectively evaluated for impairment loss factor for the respective portfolio segment in order to determine the allowance for loans collectively evaluated for impairment.
When assigning a credit risk rating to a loan, management utilizes the Bank’s internal nine-point credit risk rating system.

2.Good
3.Acceptable
4.Adequate
5.Watch
6.Special Mention
7.Substandard
8.Doubtful
9.Loss
 
Loans rated 1 to 5 are considered pass ratings. An asset is classified substandard if it is inadequately protected by the current net worth and paying capacity of the obligor or of the collateral pledged, if any. Substandard assets have well defined weaknesses based on objective evidence, and are characterized by the distinct possibility that the Company will sustain some loss if the deficiencies are not corrected. Assets classified as doubtful have all of the weaknesses inherent in those classified substandard with the added characteristic that the weaknesses present make collection or liquidation in full highly questionable and improbable based on current circumstances. Assets classified as loss are those considered uncollectible and of such little value that their continuance as assets is not warranted. Assets which do not currently expose the Company to sufficient risk to warrant classification in one of the aforementioned categories, but possess weaknesses, are required to be designated special mention.
The following tables presents the Company’s loans held-for-investment and current period gross charge-offs, excluding PCD loans, by loan class, credit risk ratings and year of origination, at December 31, 2024, and December 31, 2023, (in thousands):

Past Due and Non-Accrual Loans

Included in loans receivable held-for-investment are loans for which the accrual of interest income has been discontinued due to deterioration in the financial condition of the borrowers. The recorded investment of these non-accrual loans was $14.3 million and $10.1 million at December 31, 2024, and December 31, 2023, respectively. Generally, originated loans are placed on non-accrual status when they become 90 days or more delinquent, or sooner if considered appropriate by management, and remain on non-accrual status until they are brought current, have six consecutive months of performance under the loan terms, and factors indicating reasonable doubt about the timely collection of payments no longer exist. Therefore, loans may be current in accordance with their loan terms, or may be less than 90 days delinquent and still be on a non-accruing status.
 
When an individual loan no longer demonstrates the similar credit risk characteristics as other loans within its current segment, the Company evaluates each for expected credit losses on an individual basis. All non-accrual loans $500,000 and above and all loans designated as TDRs prior to adoption of ASU 2022-02 are individually evaluated. The non-accrual amounts included in loans individually evaluated for impairment were $9.6 million and $6.0 million at December 31, 2024, and December 31, 2023, respectively. Loans on non-accrual status with principal balances less than $500,000, and therefore not meeting the Company’s definition of an individually evaluated loan, amounted to $4.7 million at December 31, 2024, and $4.1 million at December 31, 2023. Loans past due 90 days or more and still accruing interest were $1.2 million and $1.3 million at December 31, 2024, and December 31, 2023, respectively, and consisted of loans that are well-secured and in the process of collection. 

The following tables set forth the detail, and delinquency status, of non-performing loans (non-accrual loans and loans past due 90 days or more and still accruing), net of deferred fees and costs, at December 31, 2024, and December 31, 2023, excluding PCD loans (in thousands):

Collateral-Dependent Loans

Loans for which the borrower is experiencing financial difficulty and repayment is expected to be provided substantially through the operation or sale of the collateral are considered to be collateral-dependent loans. Collateral can have a significant financial effect in mitigating exposure to credit risk and, where there is sufficient collateral, an allowance for credit losses is not recognized or is minimal. For collateral-dependent loans, the allowance for credit losses is individually assessed based on the fair value of the collateral less estimated costs of sale. The Company's collateral-dependent loans are secured by real estate, inventory and equipment. Collateral values are generally based on appraisals, which are adjusted for changes in market indices. As of December 31, 2024 and December 31, 2023, the Company had $8.7 million and $7.9 million of collateral-dependent impaired loans, respectively. The collateral-dependent loans at December 31, 2024 consisted of $5.2 million of commercial real estate loans, $1.7 million of multifamily loans, $1.5 million of commercial and industrial loans, and $264,000 of one-to-four family residential loans. The collateral-dependent loans at December 31, 2023 consisted of $5.7 million of commercial real estate loans, $1.9 million of multifamily loans, and $298,000 of one-to-four family residential loans. For the years ended December 31, 2024 and 2023, there were no significant deterioration or changes in the collateral securing these loans.

Loan Modifications Made to Borrowers Experiencing Financial Difficulty

Effective January 1, 2023, the Company adopted ASU 2022-02, which eliminated the accounting for TDRs while expanding loan modification and vintage disclosure requirements. See Note 1- “Summary of Significant Accounting Policies” for further information.

The following tables present the amortized cost basis at December 31, 2024 and 2023 of loan modifications made to borrowers experiencing financial difficulty that were modified during the years ended December 31, 2024 and 2023 by class and by type of modification (dollars in thousands):

During the third quarter of 2024, the loan experienced credit deterioration and was put on non-accrual status. The loan received principal forgiveness of $878,000 in the third quarter of 2024 and made a payment of $10.0 million during the fourth quarter of 2024. The remaining $2.5 million balance of this loan was current as of December 31, 2024, but remains on non-accrual status.

For modified loans, a subsequent payment default is defined in terms of delinquency, when a principal or interest payment is 90 days past due or classified into non-accrual status during the reporting period. during the preceding twelve months, there were six commercial and industrial loans with a balance of approximately $1.1 million that subsequently defaulted and were charged-off during the year ended December 31, 2024.

The Company closely monitors the performance of loans that are modified to borrowers experiencing financial difficulty to understand the effectiveness of the modification efforts. The following tables present the aging analysis of loan modifications made to borrowers experiencing financial difficulty during the years ended December 31, 2024 and 2023 (in thousands):

During the third quarter of 2024, the loan experienced credit deterioration and was put on non-accrual status. The loan received principal forgiveness of $878,000 in the third quarter of 2024 and made a payment of $10.0 million during the fourth quarter of 2024. The remaining $2.5 million balance of this loan was current as of December 31, 2024, but remains on non-accrual status.

Allowance for Credit Losses (“ACL”) on Loans

Credit Loss [Abstract]  
Allowance for Credit Losses (“ACL”) on Loans Allowance for Credit Losses ("ACL") on Loans 
Allowance for Collectively Evaluated Loans Held-for-Investment

In estimating the quantitative component of the allowance on a collective basis, the Company uses a risk rating migration model which calculates an expected life of loan loss percentage for each loan by generating probability of default and loss given default metrics. These metrics are multiplied by the exposure at the potential default, taking into consideration estimated prepayments, to calculate the quantitative component of the ACL. The metrics are based on the migration of loans from performing to loss by credit risk rating or delinquency categories using historical life-of-loan analysis periods for each loan portfolio pool, and the severity of loss, based on the aggregate net lifetime losses incurred using the Company's own historical loss experience and comparable peer data loss history. The model's expected losses based on loss history are adjusted for qualitative adjustments to address risks that may not be adequately represented in the risk rating migration model. Among other things, these adjustments include and account for differences in: (i) changes in lending policies and procedures; (ii) changes in local, regional, national, and international economic and business conditions and developments that affect the collectability of our portfolio, including the condition of various market segments; (iii) changes in the experience, ability and depth of lending management and other relevant staff; (iv) changes in the quality of our loan review system; (v) the existence and effect of any concentrations of credit, and changes in the level of such concentrations; and (vi) the effect of other external factors such as competition and legal and regulatory requirements on the level of estimated credit losses in our existing portfolio.

The Company utilizes a two-year reasonable and supportable forecast period after which estimated losses revert to historical loss experience immediately for the remaining life of the loan. In establishing its estimate of expected credit losses, the Company utilizes five externally-sourced forward-looking economic scenarios developed by Moody's Analytics (“Moody's”) so as to incorporate uncertainties related to the economic environment. These scenarios, which range from more benign to more severe economic outlooks, include a “most likely outcome” (the “Baseline” scenario) and four less likely scenarios referred to as the “Upside” and “Downside” scenarios. Each scenario is assigned a weighting with a majority of the weighting placed on the Baseline scenario and lower weights placed on both the Upside and Downside scenarios. The weighting assigned by management is based on the economic outlook and available information at the reporting date. The model projects economic variables under each scenario based on detailed statistical analyses. The Company has identified and selected key variables that most closely correlated to its historical credit performance, which include: Gross domestic product, unemployment, and three collateral indices: the Commercial Property Price Index, the Commercial Property Price Apartment Index and the Case-Shiller Home Price Index.

Allowance for Individually Evaluated Loans

The Company measures specific reserves for individual loans that do not share common risk characteristics with other loans, consisting of all loans previously modified as TDRs (prior to the adoption of ASU 2022-02) and non-accrual loans with an outstanding balance of $500,000 or greater. Loans individually evaluated for impairment are assessed to determine whether the loan’s carrying value is not in excess of the estimated fair value of the collateral less cost to sell, if the loan is collateral-dependent, or the present value of the expected future cash flows, if the loan is not collateral-dependent. Management performs an evaluation of each individually evaluated loan and generally obtains updated appraisals as part of the evaluation. In addition, management adjusts estimated fair values down to appropriately consider recent market conditions, our willingness to accept a lower sales price to effect a quick sale, and costs to dispose of any supporting collateral. Determining the estimated fair value of underlying collateral (and related costs to sell) can be difficult in illiquid real estate markets and is subject to significant assumptions and estimates. Management employs an independent third-party management firm that specializes in appraisal preparation and review to ascertain the reasonableness of updated appraisals. Projecting the expected cash flows for TDRs (prior to the adoption of ASU 2022-02) which are not collateral-dependent is inherently subjective and requires, among other things, an evaluation of the borrower’s current and projected financial condition. Individually evaluated loans that have no impairment losses are not considered for collective allowances described above. Upon adoption of ASU 2022-02, the Company no longer establishes a specific reserve for loan modifications to borrowers experiencing financial difficulty. Instead, these loan modifications are included in their respective pool and a historical loss rate is applied to the current loan balance to arrive at the quantitative and qualitative baseline portion of the allowance for credit losses.
Allowance for Credit Losses – Off-Balance Sheet Exposures

An ACL for off-balance-sheet exposures represents an estimate of expected credit losses arising from off-balance sheet exposures such as loan commitments, standby letters of credit and unused lines of credit (loans already on the books). Commitments to fund unused lines of credit are agreements to lend additional funds to customers as long as there have been no violations of any of the conditions established in the agreements (original or restructured). Commitments to originate loans generally have a fixed expiration or other termination clauses, which may require payment of a fee. Since some of these loan commitments are expected to expire without being drawn upon, total commitments do not necessarily represent future cash requirements. The reserve for off-balance sheet exposures is determined using the CECL reserve factor in the related funded loan segment, adjusted for an average historical funding rate. The allowance for credit losses for off-balance sheet credit exposures is recorded in other liabilities on the consolidated balance sheets and the corresponding provision is included in other non-interest expense.

The table below summarizes the allowance for credit losses for off-balance sheet credit exposures as of, and for the years ended December 31, 2024 and 2023 (in thousands):

The allowance for credit losses on loans decreased to $35.2 million at December 31, 2024, compared to $37.5 million at December 31, 2023, primarily due to a decrease in loan balances and an improvement in the macroeconomic forecast. The decreases were partially offset by increases in the reserves related to the commercial and industrial and home equity loan portfolios due to an increase in non-performing loans in these categories and loan balances.

The BTFP was established by the Board of Governors of the Federal Reserve System. The BTFP was created in March 2023 in response to industry events to provide banks with additional liquidity via a secured line of credit collateralized by eligible pledged securities. In January 2024, the Company borrowed $300 million from the Federal Reserve Bank through the BTFP program at favorable terms and conditions and invested the proceeds at higher rates. These borrowings were repaid in full as of December 31, 2024. The BTFP ceased providing borrowings in March 2024.
    
The Company has the ability to obtain additional funding from the FHLB and Federal Reserve Bank discount window of approximately $1.62 billion, utilizing unencumbered and unpledged securities of $683.4 million and multifamily loans of $934.8 million at December 31, 2024. The Company expects to have sufficient funds available to meet current commitments in the normal course of business.

The Company has determined that it is not required to establish a valuation reserve for the deferred tax asset since it is “more likely than not” that the deferred tax asset will be realized through future reversals of existing taxable temporary differences.  The conclusion that it is “more likely than not” that the deferred tax asset will be realized is based on the history of earnings and the prospects for continued profitability.  Management will continue to review the tax criteria related to the recognition of deferred tax assets.
 
As a savings institution, the Bank is subject to a special federal tax provision regarding its frozen tax bad debt reserve. At December 31, 2024 and December 31, 2023, the Bank’s federal tax bad debt base-year reserve was $5.9 million, with a related net deferred tax liability of $1.7 million, which has not been recognized since the Bank does not expect that this reserve will become taxable in the foreseeable future. Events that would result in taxation of this reserve include redemptions of the Bank’s stock or certain excess distributions by the Bank to the Company.

Retirement Benefits [Abstract]  
Retirement Benefits Retirement Benefits 
 
The Company has a 401(k) plan for its employees, which grants eligible employees (those salaried employees with at least 30 days of service) the opportunity to invest from 2% to 100% (subject to certain IRS limitations) of their base compensation in certain investment alternatives. The Company contributes an amount equal to 25% of employee contributions on the first 6% of base compensation contributed by eligible employees for the first three years of participation. After three years of participation, the Company's matching contribution increases from 25% to 50% of an employee’s contributions, on the first 6% of base compensation contributed by eligible employees. A member becomes fully vested in the Company’s contributions upon (a) completion of five years of service, or (b) normal retirement, early retirement, permanent disability, or death. The Company’s contribution to this plan amounted to approximately $736,000, $629,000, and $553,000 for the years ended December 31, 2024, 2023, and 2022, respectively. 
 
The Company maintains the Northfield Bank ESOP. The ESOP is a tax-qualified plan invested in the Company’s common stock. The ESOP provides employees with the opportunity to receive a funded retirement benefit from the Bank, based on the value of the Company’s common stock. The ESOP purchased 2,463,884 shares of the Company’s common stock in the Company’s initial public offering at a price of $7.13 per share, as adjusted. This purchase was funded with a loan from Northfield Bancorp, Inc. to the ESOP. The outstanding balance of the loan at December 31, 2024 and 2023 was $5.9 million and $6.7 million, respectively. The shares of the Company’s common stock purchased in the initial public offering are pledged as collateral for the loan. Shares are released for allocation to participants as loan payments are made. A total of 106,215 and 105,463 shares were released and allocated to participants of the ESOP for the years ended December 31, 2024 and 2023, respectively. Cash dividends on unallocated shares are utilized to satisfy required debt payments, which releases additional shares to participants.
 
Upon completion of the Company’s second-step conversion, a second ESOP was established for employees in 2013, which purchased 1,422,357 shares of the Company’s common stock at a price of $10.00 per share. The purchase was funded with a loan from Northfield Bancorp, Inc. to the second ESOP. The outstanding balance at December 31, 2024 and 2023 was $9.4 million and $9.8 million, respectively. The shares of the Company’s common stock purchased in the second-step conversion are pledged as collateral for the loan. Shares are released for allocation to participants as loan payments are made. A total of 54,083 and 54,581 shares were released and allocated to participants of the second ESOP for the years ended December 31, 2024 and 2023, respectively. Cash dividends on unallocated shares are utilized to satisfy required debt payments. Dividends on allocated shares are utilized to prepay debt which releases additional shares to participants.
 
ESOP compensation expense for both plans for the years ended December 31, 2024, 2023, and 2022 was $1.1 million, $1.3 million, and $1.7 million, respectively.  
The Company maintains a Supplemental Employee Stock Ownership Plan (the “SESOP”), a non-qualified plan, that provides supplemental benefits to certain executives who are prevented from receiving the full benefits contemplated by the ESOP’s benefit formula due to tax law limits for tax-qualified plans. The supplemental payments for the SESOP consist of cash payments representing the value of Company shares that cannot be allocated to participants under the ESOP due to legal limitations imposed on tax-qualified plans. The Company's required contributions to the SESOP plan were $30,000, $53,000, and $54,000 for the years ended December 31, 2024, 2023, and 2022, respectively. 
 
The Company provides post-retirement medical and life insurance to a limited number of retired individuals. The Company also provides retiree life insurance benefits to all qualified employees, up to certain limits.

Benefit payments of approximately $109,000, $106,000, and $81,000 were made in 2024, 2023, and 2022, respectively. The benefits expected to be paid under the postretirement health benefits plan for the next five years are as follows: $107,000 in 2025; $103,000 in 2026; $100,000 in 2027; $96,000 in 2028; and $91,000 in 2029. The benefit payments expected to be paid in the aggregate for the years 2030 through 2034 are $385,000. The expected benefits are based on the same assumptions used to measure the Company’s benefit obligation at December 31, 2024, and include estimated future employee service.
 
The Company maintains a nonqualified plan to provide for the elective deferral of all or a portion of director fees by members of the Board of Directors, deferral of all or a portion of the compensation and/or annual incentive compensation payable to eligible employees of the Company, and to provide to certain officers of the Company benefits in excess of those permitted to be paid by the Company’s savings plan, ESOP, and profit-sharing plan under the applicable Internal Revenue Code. The plan obligation was approximately $15.8 million and $14.7 million at December 31, 2024 and 2023, respectively, and is included in accrued expenses and other liabilities on the consolidated balance sheets. Income (loss) under this plan was $1.7 million for the year ended December 31, 2024, $1.7 million for the year ended December 31, 2023, and $(2.2) million for the year ended December 31, 2022. The Company invests to fund this future obligation, in various mutual funds designated as trading securities. The securities are marked-to-market through current period earnings as a component of non-interest income. Accrued obligations under this plan are credited or charged with the return on the trading securities portfolio as a component of compensation and benefits expense.

Equity Incentive Plans Equity Incentive Plans
 
In 2019, the Northfield Bancorp, Inc. 2019 Equity Incentive Plan (the “2019 EIP”) was approved by stockholders of the Company. Under the 2019 EIP, the maximum number of shares of stock that may be delivered to participants in the form of stock options and stock appreciation rights (“SARs”) is 6,000,000. To the extent an equity award is issued in the form of a restricted stock grant, or restricted stock unit, the number of stock options/SARs that can be granted is reduced by 4.5. The maximum number of shares of stock that may be delivered to participants in the form of restricted stock awards and restricted stock units is 1,333,333 shares. As of December 31, 2024, a total of 2,436,734 stock options, SARs and restricted stock awards or restricted stock units remained available for issuance under the 2019 EIP, of which the maximum number of restricted stock awards and restricted stock units available for issuance was 541,496.

Previously, the Company maintained the Northfield Bancorp, Inc. 2014 Equity Incentive Plan (the “2014 EIP”), which allowed the Company to grant common stock or options to purchase common stock at specific prices to directors and employees of the Company. The 2014 EIP provided for the issuance or delivery of up to 4,978,249 shares (1,422,357 restricted shares and 3,555,892 stock options) of Northfield Bancorp, Inc. common stock subject to certain plan limitations. Upon approval of the 2019 EIP, the 2014 EIP was frozen and equity awards that would otherwise have been available for issuance were no longer available for grant, however, options previously granted under the 2014 EIP still remain outstanding and exercisable.

There were no stock options granted in 2024, 2023 or 2022.

During the years ended December 31, 2024, 2023, and 2022, the Company recorded $2.3 million, $2.4 million, and $1.8 million of stock-based compensation, respectively.
The following table is a summary of the Company’s stock options as of December 31, 2024, and changes therein during the year then ended:

Commitments and Contingencies Disclosure [Abstract]  
Commitments and Contingencies Commitments and Contingencies
 
The Company, in the normal course of business, is party to commitments that involve, to varying degrees, elements of risk in excess of the amounts recognized in the consolidated financial statements. These commitments include unused lines of credit and commitments to extend credit.
 
At December 31, 2024 and 2023, the following commitment and contingent liabilities existed that are not reflected in the accompanying consolidated financial statements (in thousands):
 December 31,
 20242023
Commitments to extend credit$51,260 $6,972 
Unused lines of credit261,783 292,721 
Standby letters of credit5,362 6,391 
The Company’s maximum exposure to credit losses in the event of nonperformance by the other party to these commitments is represented by the contractual amount. The Company uses the same credit policies in granting commitments and conditional obligations as it does for amounts recorded on the consolidated balance sheets. These commitments and obligations do not necessarily represent future cash flow requirements.  The Company evaluates each customer’s creditworthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary, is based on management’s assessment of risk. Standby letters of credit are conditional commitments issued by the Company to guarantee the performance of a customer to a third-party. The guarantees generally extend for a term of up to one year and are fully collateralized. For each guarantee issued, if the customer defaults on a payment to the third party, the Company would have to perform under the guarantee. The unamortized fee on standby letters of credit approximates their fair value; such fees were insignificant at both December 31, 2024 and 2023.
The Company maintains an allowance for credit losses on commitments to extend credit. The reserve for off-balance sheet exposures is determined using the CECL reserve factor in the related funded loan segment, adjusted for an average historical funding rate. At December 31, 2024 and 2023, the allowance was $518,000 and $236,000, respectively, and is recorded in other liabilities on the consolidated balance sheets. The corresponding provision is included in other non-interest expense. For further details on the allowance for credit losses on off-balance sheet exposures refer to Note 6 - “Allowance for Credit Losses (“ACL”) on Loans.”
 
At December 31, 2024, the Company was obligated under non-cancelable operating leases on property used for banking purposes. Most leases contain escalation clauses and renewal options which provide for increased rentals as well as for increases in certain property costs including real estate taxes, common area maintenance, and insurance. For further details on leases see Note 20 - “Leases.”
 
In the normal course of business, the Company may be a party to various outstanding legal proceedings and claims. In the opinion of management, the consolidated financial statements will not be materially affected by the outcome of such legal proceedings and claims.
 
The Bank has entered into employment and change in control agreements with its President and Chief Executive Officer and the other executive officers of the Company to ensure the continuity of executive leadership, to clarify the roles and responsibilities of executives, and to make explicit the terms and conditions of executive employment. These agreements are for a term of three years subject to review and annual renewal, and provide for certain levels of base annual salary and in the event of a change in control, as defined, or in the event of termination, as defined, certain levels of base salary, bonus payments, and benefits for a period of up to three years.

Regulatory Requirements [Abstract]  
Regulatory Requirements Regulatory Requirements
 
Federal regulations require federally insured depository institutions to meet several minimum capital standards: a common equity Tier 1 capital to risk-based assets ratio of 4.5%, a Tier 1 capital to risk-based assets ratio of 6.0%, a total capital to risk-based assets of 8.0%, and a 4.0% Tier 1 capital to total assets leverage ratio.

Under prompt corrective action regulations, the OCC is required to take certain supervisory actions (and may take additional discretionary actions) with respect to an undercapitalized institution.  Such actions could have a direct material effect on the institution’s financial statements.  The regulations establish a framework for the classification of savings institutions into five categories: well capitalized, adequately capitalized, undercapitalized, significantly undercapitalized, and critically undercapitalized.  Generally, an institution is considered well capitalized if it has a leverage (Tier 1) ratio of 5.0% or greater, a common equity Tier 1 ratio of 6.5% or greater, a Tier 1 risk-based capital ratio of 8.0% or greater, and a total risk-based capital ratio of 10.0% or greater.

The foregoing capital ratios are based in part on specific quantitative measures of assets, liabilities, and certain off-balance-sheet items as calculated under regulatory accounting practices. Capital amounts and classifications also are subject to qualitative judgments by the regulators about capital components, risk weighting, and other factors.
 
Under the U.S. Basel III capital framework, both Northfield Bank and the Company must maintain minimum capital requirements which include: (i) a common equity Tier 1 capital to risk-based assets ratio of 4.5%; (ii) a Tier 1 capital to risk-based assets ratio of 6%; (iii) a total capital to risk-based assets of 8%; and (iv) a Tier 1 capital to total assets leverage ratio of 4%. In addition to establishing the minimum regulatory capital requirements, the regulations limit capital distributions and certain discretionary bonus payments to management if the institution does not hold a “capital conservation buffer” consisting of 2.5% of common equity Tier 1 capital to risk-weighted assets in addition to the amount necessary to meet its minimum risk-based capital requirements.

The federal banking agencies developed a “Community Bank Leverage Ratio” (“CBLR”) (the ratio of a bank’s tangible equity capital to average total consolidated assets) for financial institutions with assets of less than $10 billion. A qualifying community bank that exceeds this ratio will be deemed to be in compliance with all other capital and leverage requirements, including the capital requirements to be considered “well capitalized” under Prompt Corrective Action statutes. The federal banking agencies have approved 9% as the minimum capital for the CBLR. Northfield Bank and Northfield Bancorp elected to opt into the CBLR framework.

At December 31, 2024, and 2023, as set forth in the following tables, both Northfield Bank and the Company exceeded all of the regulatory capital requirements to which they were subject at such dates.

The following tables present the assets reported on the consolidated balance sheets at their estimated fair value as of December 31, 2024 and 2023, by level within the fair value hierarchy as required by the Fair Value Measurements and Disclosures Topic of the FASB Accounting Standards Codification. Financial assets and liabilities are classified in their entirety based on the level of input that is significant to the fair value measurement.  The fair value hierarchy is as follows:
Level 1 Inputs – Unadjusted quoted prices in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date.
Level 2 Inputs – Inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. These include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability (for example, interest rates, volatilities, prepayment speeds, loss severities, credit risks and default rates) or inputs that are derived principally from or corroborated by observable market data by correlations or other means.
Level 3 Inputs – Significant unobservable inputs that reflect the Company’s own assumptions that market participants would use in pricing the assets or liabilities.

    The valuation techniques described below were used to measure fair value of financial instruments in the tables below on a recurring basis and a non-recurring basis as of December 31, 2024 and 2023.
Debt Securities Available-for-Sale: The estimated fair values for mortgage-backed securities, corporate, and other debt securities are obtained from an independent nationally recognized third-party pricing service. The estimated fair values are derived primarily from cash flow models, which include assumptions for interest rates, credit losses, and prepayment speeds. Broker/dealer quotes are utilized as well, when such quotes are available and deemed representative of the market. The significant inputs utilized in the cash flow models are based on market data obtained from sources independent of the Company (Observable Inputs), and are therefore classified as Level 2 within the fair value hierarchy. There were no transfers of securities between Level 1 and Level 2 during the years ended December 31, 2024 and 2023. 
Trading Securities: Fair values are derived from quoted market prices in active markets.  The assets consist of publicly traded mutual funds.
Equity Securities: Fair values of equity securities consisting of publicly traded mutual funds are derived from quoted market prices in active markets.
Loans Individually Evaluated for Impairment: At December 31, 2024, and December 31, 2023, the Company had loans individually evaluated for impairment (excluding PCD loans) with outstanding principal balances of $7.2 million and $6.0 million, respectively, which were recorded at their estimated fair value of $4.1 million and $4.3 million, respectively. The Company recorded a net increase in the specific reserve for impaired loans of $1.2 million and $7,000 for the years ended December 31, 2024 and 2023, respectively. Net charge-offs of $6.6 million and $6.4 million were recorded for the years ended December 31, 2024 and 2023, respectively, utilizing Level 3 inputs. For purposes of estimating the fair value of impaired loans, management utilizes independent appraisals, if the loan is collateral-dependent, adjusted downward by management, as necessary, for changes in relevant valuation factors subsequent to the appraisal date, or the present value of expected future cash flows for non-collateral-dependent loans.
     Other Real Estate Owned: At December 31, 2024 and December 31, 2023 the Company had no assets acquired through foreclosure.
In addition, the Company may be required, from time to time, to measure the fair value of certain other financial assets on a non-recurring basis in accordance with U.S. GAAP. The adjustments to fair value usually result from the application of lower-of-cost-or-market accounting or write downs of individual assets.
Fair Value of Financial Instruments
 The FASB ASC Topic for Financial Instruments requires disclosure of the fair value of financial assets and financial liabilities, including those financial assets and financial liabilities that are not measured and reported at fair value on a recurring or non-recurring basis. The methodologies for estimating the fair value of financial assets and financial liabilities that are measured at fair value on a recurring or non-recurring basis are discussed above. The following methods and assumptions were used to estimate the fair value of other financial assets and financial liabilities not already discussed above:
(a)    Cash and Cash Equivalents
Cash and cash equivalents are short-term in nature with original maturities of three months or less; the carrying amount approximates fair value. Certificates of deposit having original terms of six-months or less; the carrying value generally approximates fair value. Certificates of deposit with an original maturity of six months or greater; the fair value is derived from discounted cash flows.
     (b)    Debt Securities (Held-to-Maturity)
The estimated fair values for substantially all of our securities are obtained from an independent, nationally recognized pricing service. The independent pricing service utilizes market prices of same or similar securities whenever such prices are available. Prices involving distressed sellers are not utilized in determining fair value. Where necessary, the independent third-party pricing service estimates fair value using models employing techniques such as discounted cash flow analysis. The assumptions used in these models typically include assumptions for interest rates, credit losses, and prepayments, utilizing market observable data where available.
(c)    Investments in Equity Securities at Net Asset Value Per Share
The Company uses net asset value as a practical expedient to record its investment in a private SBA Loan Fund since the shares in the fund are not publicly traded, do not have a readily determinable fair value, and the net asset value per share is calculated in a manner consistent with the measurement principles of an investment company.
(d)    FHLBNY Stock
FHLBNY stock is carried at cost, which approximates fair value, since this is the amount for which it could be redeemed and there is no active market for this stock. Due to restrictions placed on the transferability of FHLBNY stock it is not practical to determine the fair value as there is no active market for this stock.
(e)    Loans (Held-for-Investment)
Fair values are estimated for portfolios of loans with similar financial characteristics. Loans are segregated by type such as originated and purchased, and further segregated by residential mortgage, construction, land, multifamily, commercial and consumer. Each loan category is further segmented into amortizing and non-amortizing and fixed and adjustable rate interest terms and by performing and non-performing categories. The fair value of loans is estimated using a discounted cash flow analysis. The discount rates used to determine fair value use interest rate spreads that reflect factors such as liquidity, credit, and non-performance risk of the loans.
(f)    Loans (Held-for-Sale)
Held-for-sale loans are carried at the lower of aggregate cost or estimated fair value, less costs to sell, and therefore fair value is equal to carrying value.
 (g)    Deposits
 The fair value of deposits with no stated maturity, such as interest and non-interest-bearing demand deposits, savings, NOW and money market accounts, is equal to the amount payable on demand. The fair value of certificates of deposit is based on the discounted value of contractual cash flows. The discount rate is estimated using the rates currently offered for deposits of similar remaining maturities.
 
(h)    Commitments to Extend Credit and Standby Letters of Credit
 
The fair value of commitments to extend credit and standby letters of credit is estimated using the fees currently charged to enter into similar agreements, taking into account 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 value of off-balance-sheet commitments is insignificant and therefore not included in the following table.

(i)    Borrowings

The fair value of borrowed funds is estimated by discounting future cash flows based on rates currently available for debt with similar terms and remaining maturity.

(j)    Advance Payments by Borrowers for Taxes and Insurance
 
Advance payments by borrowers for taxes and insurance have no stated maturity; the fair value is equal to the amount currently payable.

(k)    Derivatives

The fair value of the Company's derivatives is determined using discounted cash flow analysis using observable market-based inputs, which are considered Level 2 inputs.

The estimated fair values of the Company’s significant financial instruments at December 31, 2024 and 2023, are presented in the following tables (in thousands):

Limitations
 
Fair value estimates are made at a specific point in time, based on relevant market information and information about the financial instrument. These estimates do not reflect any premium or discount that could result from offering for sale at one time the Company’s entire holdings of a particular financial instrument. Because no market exists for a significant portion of the Company’s financial instruments, fair value estimates are based on judgments regarding future expected losses, current economic conditions, risk characteristics of various financial instruments, and other factors. These estimates are subjective in nature and involve uncertainties and matters of significant judgment and, therefore, cannot be determined with precision. Changes in assumptions could significantly affect the estimates.

Fair value estimates are based on existing on- and off-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. 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.

Revenue from Contract with Customer [Abstract]  
Revenue Recognition Revenue Recognition
The Company records revenue from contracts with customers in accordance with ASU 2014-09, Revenue from Contracts with Customers ("Topic 606"). The standard’s core principle is that a company will recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. Topic 606 does not apply to revenue associated with financial instruments, including revenue from loans and securities, which comprise the majority of the Company’s revenue.
The Company’s revenue streams that are within the scope of Topic 606 include service charges on deposit accounts, ATM and card interchange fees, investment services fees, and other miscellaneous income. Fees and service charges for customer services include: (i) service charges on deposit accounts, including account maintenance fees, analysis fees, insufficient funds fees, wire fees, and other deposit related fees; (ii) ATM and card interchange fees, which include fees generated when a Bank cardholder uses a non-Bank ATM or a non-Bank cardholder uses a Bank ATM, and fees earned whenever the Bank's debit cards are processed through card payment networks such as Visa; and (iii) investment services fees earned through partnering with a third-party investment and brokerage service firm to provide insurance and investment products to customers. The Company's performance obligation for fees and service charges is satisfied and related revenue recognized immediately or in the month of performance of services. For the years ended December 31, 2024 and 2023, other income primarily included fee income on interest rate swaps and rental income from subleasing one of the Company's branches to a third party. For the year ended December 31, 2022, other income primarily included rental income from subleasing one of the Company's branches to a third party, loan servicing fees, and fee income on interest rate swaps.

Leases [Abstract]  
Leases Leases
The Company’s leases primarily relate to real estate property for branches and office space with terms extending from two months up to 31.5 years. At December 31, 2024, all of the Company's leases are classified as operating leases, which are required to be recognized on the consolidated balance sheets as a right-of-use asset and a corresponding lease liability.

The Company determines if an arrangement is a lease at inception. Operating leases are included in operating lease right-of-use assets and operating lease liabilities on the consolidated balance sheets. Right-of-use assets represent the right to use an underlying asset for the lease term and lease liabilities represent the obligation to make lease payments arising from the lease. Operating lease right-of-use assets and liabilities are recorded at the present value of lease payments over the lease term. As the Company's leases do not provide an implicit rate, the Company uses its incremental borrowing rate, at lease inception, over a similar term in determining the present value of lease payments. Certain leases include options to renew, with one or more renewal terms ranging from five to ten years. If the exercise of a renewal option is considered to be reasonably certain, the Company includes the extended term in the calculation of the right-of-use asset and lease liability.

At December 31, 2024, the Company’s operating lease right-of-use assets and operating lease liabilities included on the consolidated balance sheet were $27.8 million and $32.2 million, respectively. At December 31, 2023, the Company’s operating lease right-of-use assets and operating lease liabilities included on the consolidated balance sheet were $30.2 million and $35.2 million, respectively. Operating lease expense is recognized on a straight-line basis over the lease term, while variable lease payments are recognized as incurred. Variable lease payments include common area maintenance charges, real estate taxes, repairs and maintenance costs and utilities. Operating and variable lease expenses are recorded in occupancy expense on the consolidated statements of comprehensive income.
Supplemental lease information at or for the years ended December 31, 2024, 2023, and 2022 is as follows (dollars in thousands):

Derivative Instruments and Hedging Activities Disclosure [Abstract]  
Derivatives Derivatives
The Company has interest rate derivatives resulting from a service provided to certain qualified borrowers in a loan-related transaction and, therefore, are not used to manage interest rate risk in the Company’s assets or liabilities. The interest rate swap agreement which the Company executed with the commercial borrower is collateralized by the borrower’s commercial real estate financed by the Company. The collateral exceeds the maximum potential amount of future payments under the credit derivative. As these interest rate swaps do not meet the hedge accounting requirements, changes in the fair value of both the customer swaps and the offsetting swaps are recognized directly in earnings.

At December 31, 2024, the Company had 13 interest rate swaps with a notional amount of $95.7 million. At December 31, 2023, the Company had ten interest rate swaps with a notional amount of $72.7 million. The Company recorded fee income related to these swaps of $685,000 and $383,000 for the years ended December 31, 2024 and 2023, respectively.

Segment Reporting [Abstract]  
Segment Information Segment Information
The Company's reportable segment is determined by the CODM, based upon information provided about the Company's products and services offered, primarily banking operations, originating loans and offering a variety of deposit products. The segment is also distinguished by the level of information provided by the CODM, who uses such information to review performance of various components of the business (such as branches) which are then aggregated if operating performance, products and services, and customers are similar. The CODM will evaluate the performance of the Company's business components such as by evaluating revenue streams, significant expenses, and budget to actual results in assessing the Company's segment and in the determination of allocating resources. The CODM uses the revenue streams to evaluate product pricing and significant expenses to assess performance and evaluate return on assets. The CODM uses consolidated net income to benchmark the Company against its competitors. The benchmarking analysis coupled with monitoring of budget to actual results are used in assessment performance and in establishing compensation. Loans and investments provide the revenues in the banking operations. Interest expense, provisions for credit losses, and payroll provide the significant expenses in the banking operations. The Company's operations are all domestic.
Segment performance is evaluated using consolidated net income. Information reported internally for performance assessment by the CODM follows, inclusive of reconciliations of significant segment totals to the consolidated financial statements.

Cybersecurity Risk Management and Strategy
Our cybersecurity risk management program is an integrated component of the Enterprise Risk Management strategy designed to protect the confidentiality, integrity and availability of our critical systems and information.
We design and evaluate our program based on industry recognized standards such as the National Institute of Standards and Technology Cybersecurity Framework and the Center for Internet Security Controls. This does not imply that we meet any particular technical standards, specifications, or requirements, but rather that we use these standards as a guide to help us identify, assess, and manage cybersecurity risks relevant to our business.
Our cybersecurity risk management program is closely aligned with the Company’s business strategy. It shares common methodologies, reporting channels and governance processes that apply to other areas of enterprise risk, including third-party relationships, legal, compliance, strategic, operational, and financial. Key elements of our enterprise cybersecurity risk management program include:
implementation of policies and procedures in the areas of Information Security, Business Continuity, Disaster Recovery, Privacy, Third-Party Relationship Risk Management, Risk Management, and Incident Response;
risk assessments designed to help identify material cybersecurity risks to our critical systems, data, products, services, and our broader enterprise information technology environment;
an independent second line function, the Information Security Department, which is principally responsible for managing our cybersecurity risk assessment processes, executing our incident response plan, and monitoring of our security controls;
the use of external service providers, where appropriate, to assess, test and enhance our security controls, including penetration testing, training, and table top exercises;
a comprehensive employee training and awareness program which includes periodic security assessments to test knowledge and reinforce adoption of security processes and controls that include simulated phishing attacks;
membership with the Financial Services Information Sharing and Analysis Center (FS-ISAC) and annual participation in the Cyber Attacks against Payment Systems (CAPS) exercises;
regular reporting of cybersecurity metrics and other risk/threat information matters to both the Management Risk and CIT Committees;
a cybersecurity incident response plan that includes procedures for responding to cybersecurity incidents; and
a third-party relationships risk management process for service providers, suppliers and vendors which analyses, monitors, reports, and mitigates cyber risks associated with third-party relationships.
Risks from cybersecurity threats, including any previous cybersecurity events, have not materially affected or are reasonably likely to materially affect the Company, including its business strategy, results of operations, or financial conditions, and any expenses incurred from cybersecurity incidents have been immaterial. For a discussion of whether and how any risks from cybersecurity threats, including as a result of any previous cybersecurity incidents, have materially affected or are reasonably likely to materially affect us, including our business strategy, results of operations or financial condition, refer to Item 1A. Risk Factors – “Risks Related to Operational Matters”.

Summary of Significant Accounting Policies (Policies)
12 Months Ended
Dec. 31, 2024
Accounting Policies [Abstract]  
Basis of Presentation Basis of Presentation
 
The consolidated financial statements are comprised of the accounts of Northfield Bancorp, Inc. and its wholly owned subsidiaries, Northfield Investment, Inc. and Northfield Bank (the “Bank”), and the Bank’s wholly-owned subsidiaries, NSB Services Corp. and NSB Realty Trust.  All significant intercompany accounts and transactions have been eliminated in consolidation.
 
In preparing the consolidated financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the balance sheets and revenues and expenses during the reporting periods. Actual results may differ significantly from those estimates and assumptions. A material estimate that is particularly susceptible to significant change in the near term is the allowance for credit losses. In connection with the determination of this allowance, management generally obtains independent appraisals for significant properties. In addition, judgments related to the amount and timing of expected cash flows from purchased credit-deteriorated (“PCD”) loans, goodwill, securities valuation and impairment, and deferred income taxes, involve a higher degree of complexity and subjectivity and require estimates and assumptions about uncertain matters. Actual results may differ from the estimates and assumptions.
Recent Accounting Pronouncements Adopted Recent Accounting Pronouncements Adopted
Accounting Standards Update (“ASU”) No. 2023-07. In November 2023, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) ASU No. 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures”. The amendments in this ASU require improved reportable segment information on an annual and interim basis, primarily through enhanced disclosures about significant segment expenses and information used to assess segment performance by the Company's chief operating decision maker (“CODM”). The Company's CODM is its President and Chief Executive Officer. This update is effective for financial statements issued for fiscal years beginning after December 15, 2023, and interim periods for fiscal years beginning after December 15, 2024. ASU 2023-07 should be applied retrospectively to all prior periods presented in the financial statements. The adoption of ASU 2023-07 did not have a material effect on the Company's financial position, results of operations or financial statement disclosures as the Company operates one operating segment. See Note 23 to the consolidated financial statements.

Accounting Standards Update (“ASU”) No. 2020-04. In March 2020, the FASB issued ASU No. 2020-04, “Reference Rate Reform (“Topic 848”): Facilitation of the Effects of Reference Rate Reform on Financial Reporting” (“ASU 2020-04”), which provides temporary optional guidance to ease the potential burden in accounting for reference rate reform. The ASU provides optional expedients and exceptions for applying generally accepted accounting principles to contract modifications and hedging relationships, subject to meeting certain criteria, that reference the London Inter-Bank Offered Rate (“LIBOR”) or another reference rate expected to be discontinued. It is intended to help stakeholders during the global market-wide reference rate transition period. The guidance was effective for all entities as of March 12, 2020 through December 31, 2022. However, in December 2022, the FASB issued ASU 2022-06, deferring the sunset date to December 31, 2024. The Company has reviewed all of its LIBOR-based products and all products have been adjusted to another index or are scheduled to be adjusted at their next repricing, as LIBOR ceased to be published after June 30, 2023. The adoption of this ASU did not have a material impact on the Company's consolidated financial statements.
ASU No. 2022-02. In March 2022, the FASB issued ASU No. 2022-02, “Financial Instruments - Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures” (“ASU 2022-02”). The amendments in this ASU were issued to (1) eliminate accounting guidance for Troubled Debt Restructurings (“TDRs”) by creditors, while enhancing disclosure requirements for certain loan refinancings and restructurings by creditors when a borrower is experiencing financial difficulty; (2) require disclosures of current period gross write-offs by year of origination for financing receivables and net investments in leases. Under ASU 2022-02, the Company assesses all loan modifications to determine whether one is granted to a borrower experiencing financial difficulty, regardless of whether the modified loan terms include a concession. Modifications granted to borrowers experiencing financial difficulty may be in the form of an interest rate reduction, an other-than-insignificant payment delay, a term extension, principal forgiveness or a combination thereof. The Company adopted ASU 2022-02 on a prospective basis on January 1, 2023. The adoption of this update did not have a material effect on the Company’s consolidated financial statements. Additional disclosures are included in Note 5 to the consolidated financial statements.
Business Business
 
The Company, through its principal subsidiary, the Bank, provides a full range of banking services primarily to individuals and corporate customers in Richmond and Kings counties in New York, and Hunterdon, Mercer, Union and Middlesex counties in New Jersey. The Company is subject to competition from other financial institutions and to the regulations of certain federal and state agencies, and undergoes periodic examinations by those regulatory authorities.
Cash Equivalents Cash Equivalents
 
Cash equivalents consist of cash on hand, due from banks, and interest-bearing deposits in other financial institutions with an original term of three months or less.
Securities Securities
 
Securities are classified at the time of purchase, based on management’s intention, as debt securities held-to-maturity, debt securities available-for-sale, trading account securities or equity securities. Debt securities held-to-maturity are those that management has the positive intent and ability to hold until maturity. Debt securities held-to-maturity are carried at amortized cost, adjusted for amortization of premiums and accretion of discounts using the level-yield method over the contractual term of the securities, adjusted for actual prepayments. Debt securities available-for-sale represents all securities not classified as either held-to-maturity, trading, or equity. Debt securities available-for-sale are carried at estimated fair value with unrealized holding gains and losses (net of related tax effects) on such securities excluded from earnings, but included as a separate component of stockholders’ equity, titled “Accumulated other comprehensive income (loss).” The cost of securities sold is determined using the specific-identification method. Security transactions are recorded on a trade-date basis.

For securities available-for-sale, the Company determines if impairment is related to credit loss or non-credit loss. In making the assessment of whether a loss is from credit or other factors, management considers the extent to which fair value is less than amortized cost, any changes to the rating of the security by a rating agency and adverse conditions related to the security, among other factors. If this assessment indicates that a credit loss exists, the present value of cash flows expected to be collected from the security are compared to the amortized cost basis of the security. If the present value of cash flows is less than the amortized cost basis, a credit loss exists and an allowance is created, limited by the amount that the fair value is less than the amortized cost basis. Subsequent activity related to the credit loss component in the form of write-offs or recoveries is recognized as part of the allowance for credit losses on securities available-for-sale.

Management measures expected credit losses on held-to-maturity debt securities on a collective basis by major security type. All of the held-to-maturity securities in the Company's portfolio are issued by U.S. government agencies and are either explicitly or implicitly guaranteed by the U.S Government and therefore the expectation of nonpayment is zero. Therefore, the Company is not required to estimate an allowance for credit losses related to these securities.

The estimated fair value of debt securities, including mortgage-backed securities and corporate debt obligations is furnished by an independent third-party pricing service. The third-party pricing service primarily utilizes pricing models and methodologies that incorporate observable market inputs, including among other things, benchmark yields, reported trades, and projected prepayment and default rates. Management reviews the data and assumptions used in pricing the securities by its third-party provider for reasonableness.
The Company has made the accounting policy election to exclude accrued interest receivable on securities from the estimate of credit losses. Accrued interest receivable totaled $3.1 million and $2.4 million at December 31, 2024 and 2023, respectively, and is reported in accrued interest receivable on the consolidated balance sheets.
Trading securities are securities that are bought and may be held for the purpose of selling them in the near term. Trading securities are reported at estimated fair value, using quoted prices in active markets, with unrealized holding gains and losses reported as a component of gain (loss) on securities, net in non-interest income.
Equity securities with readily determinable fair values are stated at fair value with unrealized gains and losses reported as a component of gain (loss) on securities, net in non-interest income. Equity securities without readily determinable fair values are recorded at net asset value less any impairment, if any.
Loans and Allowance for Credit Losses Loans and Allowance for Credit Losses
 
The accounting and reporting for PCD loans and loans classified as held-for-sale differs substantially from those loans classified by the Company as held-for-investment. For purposes of reporting, discussion and analysis, management has classified its loan portfolio into three categories: (1) loans originated by the Company and held-for-sale, which are carried at the lower of aggregate cost or estimated fair value, less costs to sell, and therefore have no associated allowance for loan losses, (2) PCD loans, which are held-for-investment, and recorded at the purchase price, including non-credit discounts, plus the allowance for credit losses at the time of acquisition, and (3) loans held-for-investment, which include originated loans carried at amortized cost, and acquired loans, with no evidence of credit deterioration, initially valued at fair value on the date of acquisition, less net charge-offs and the allowance for credit losses.
 
Net loans held-for-investment are stated at unpaid principal balance, adjusted by unamortized premiums and unearned discounts, deferred origination fees and certain direct origination costs, and the allowance for credit losses. Interest income on loans is accrued and credited to income as earned. Net loan origination fees/costs are deferred and accreted/amortized to interest income over the loan’s contractual life using the level-yield method, adjusted for actual prepayments. Generally, loans held-for-sale are designated at time of origination and generally consist of newly originated fixed-rate residential loans and are recorded at the lower of aggregate cost or estimated fair value in the aggregate. Transfers of loans from held-for-investment to held-for-sale are infrequent and occur at fair value less costs to sell, with any charge-off to allowance for credit losses. Gains are recognized on a settlement-date basis and are determined by the difference between the net sales proceeds and the carrying value of the loans, including any net deferred fees or costs.
 
Net loans held-for-investment are deemed impaired when it is probable, based on current information, that the Company will not collect all amounts due in accordance with the contractual terms of the loan agreement. The Company has defined the population of loans individually evaluated for impairment to be all non-accrual loans held-for-investment with an outstanding balance of $500,000 or greater and all loans restructured as TDRs prior to the adoption of ASU 2022-02. Loan held-for-investment are individually assessed to determine that the loan’s carrying value is not in excess of the expected future cash flows, discounted at the loan's original effective interest rate, or the fair value of the underlying collateral (less estimated costs to sell) if the loan is collateral dependent. Impairments, if any, are recognized through a charge to the allowance for credit losses on loans for the amount that the loan’s carrying value exceeds the discounted cash flow analysis or estimated fair value of collateral (less estimated costs to sell) if the loan is collateral dependent.  Such amounts are charged-off when considered appropriate.  
 
Allowance for Credit Losses on Loans

Under the current expected credit losses (“CECL”) methodology adopted on January 1, 2021, the Company determines the allowance for credit losses on loans based upon a consideration of its historical portfolio loss experience, current borrower-specific risk characteristics, current conditions, forecasts of future economic conditions, reversion period, prepayments, and qualitative adjustments. The allowance is measured on a collective (loan segment) basis when similar risk characteristics exist. Loans that do not share common risk characteristics are evaluated on an individual basis and are excluded from the collective evaluation. Accrued interest on loans is excluded from the calculation of the allowance for credit losses due to the Company's non-accrual policy, which results in the reversal of uncollectible accrued interest on non-accrual loans against interest income in a timely manner. Accrued interest receivable on loans held-for-investment totaled $12.5 million and $12.8 million, respectively, at December 31, 2024 and 2023 and is reported in accrued interest receivable on the consolidated balance sheets.
Allowance for Collectively Evaluated Loans Held-for-Investment. In estimating the quantitative component of the allowance on a collective basis, the Company uses a risk rating migration model which calculates an expected life of loan loss percentage for each loan by generating probability of default and loss given default metrics. These metrics are multiplied by the exposure at default, taking into consideration prepayments, to calculate the quantitative component of the allowance. The metrics are based on the migration of loans from performing to loss by credit risk rating or delinquency categories using historical life-of-loan analysis periods for each loan portfolio pool, and the severity of loss, based on the aggregate net lifetime losses incurred using the Company's own historical loss experience and comparable peer data loss history. The model's expected losses based on loss history are adjusted for qualitative adjustments to address risks that may not be adequately represented in the risk rating migration model. Among other things, these adjustments include and account for differences in: (i) changes in lending policies and procedures; (ii) changes in local, regional, national, and international economic and business conditions and developments that affect the collectability of our portfolio, including the condition of various market segments; (iii) changes in the experience, ability and depth of lending management and other relevant staff; (iv) changes in the quality of our loan review system; (v) the existence and effect of any concentrations of credit, and changes in the level of such concentrations; and (vi) the effect of other external factors such as competition and legal and regulatory requirements on the level of estimated credit losses in our existing portfolio.

The Company utilizes a two-year reasonable and supportable forecast period after which estimated losses revert to historical loss experience immediately for the remaining life of the loan. In establishing its estimate of expected credit losses, the Company utilizes five externally-sourced forward-looking economic scenarios developed by Moody's Analytics (“Moody's”) so as to incorporate uncertainties related to the economic environment. These scenarios, which range from more benign to more severe economic outlooks, include a ‘most likely outcome’ (the “Baseline” scenario) and four less likely scenarios referred to as the “Upside” and “Downside” scenarios. Each scenario is assigned a weighting with a majority of the weighting placed on the Baseline scenario and lower weights placed on both the Upside and Downside scenarios. The weighting assigned by management is based on the economic outlook and available information at the reporting date. The model projects economic variables under each scenario based on detailed statistical analyses. The Company has identified and selected key variables that most closely correlated to its historical credit performance, which include: Gross domestic product, unemployment, and three collateral indices: the Commercial Property Price Index, the Commercial Property Price Apartment Index and the Case-Shiller Home Price Index.

Allowance for Individually Evaluated Loans. The Company measures specific reserves for individual loans that do not share common risk characteristics with other loans, consisting of all TDRs (prior to the adoption of ASU 2022-02) and non-accrual loans with an outstanding balance of $500,000 or greater. Loans individually evaluated for impairment are assessed to determine that the loan’s carrying value is not in excess of the estimated fair value of the collateral less cost to sell, if the loan is collateral-dependent, or the present value of the expected future cash flows, if the loan is not collateral-dependent. Management performs an evaluation of each individually evaluated loan and generally obtains updated appraisals as part of the evaluation. In addition, management adjusts estimated fair values down to appropriately consider recent market conditions, our willingness to accept a lower sales price to effect a quick sale, and costs to dispose of any supporting collateral. Determining the estimated fair value of underlying collateral (and related costs to sell) can be difficult in illiquid real estate markets and is subject to significant assumptions and estimates. Management employs an independent third-party management firm that specializes in appraisal preparation and review to ascertain the reasonableness of updated appraisals. Projecting the expected cash flows for historical TDRs (prior to adoption of ASU 2022-02) which are not collateral-dependent is inherently subjective and requires, among other things, an evaluation of the borrower’s current and projected financial condition. Individually evaluated loans that have no impairment losses are not considered for collective allowances described above. Upon adoption of ASU 2022-02, the Company no longer establishes a specific reserve for loan modifications to borrowers experiencing financial difficulty. Instead, these modified loans are included in their respective pool and a historical loss rate is applied to the current loan balance to arrive at the quantitative and qualitative baseline portion of the allowance for credit losses.
PCD Loans. Loans classified as PCD loans are acquired loans where there is evidence of more than insignificant credit deterioration since their origination. We consider various factors in connection with the determination of the amount of the allowance for these loans, including past due or non-accrual status, credit risk rating declines, and any write downs recorded based on the collectability of the asset, among other factors. Under the CECL methodology, the Company elected to maintain pools of loans that were previously accounted for under Accounting Standards Codification (“ASC”) Subtopic 310-30, “Loans and Debt Securities Acquired with Deteriorated Credit Quality, and will continue to account for these pools as a unit of account. Loans are only removed from existing pools if they are written off, paid off, or sold. Under CECL, the allowance for credit losses was determined for each pool and added to the pool's carrying amount to establish a new amortized cost basis. The difference between the unpaid principal balance of the pool and the new amortized cost basis is the noncredit premium or discount which will be amortized into interest income over the remaining life of the pool. Subsequent increases or decreases in the allowance for credit losses related to PCD loans is recorded as provision expense.
Off-Balance Sheet. The Company also maintains a reserve for estimated losses on off-balance sheet credit risks related to loan commitments and stand-by letters of credit. The reserve for off-balance sheet exposures is determined using the CECL reserve factor in the related funded loan segment, adjusted for an average historical funding rate. The allowance for credit losses for off-balance sheet credit exposures is recorded in other liabilities on the consolidated balance sheets and the corresponding provision is included in other non-interest expense.
 
While management uses available information to estimate credit losses on loans, future additions may be necessary based on changes in conditions, including changes in economic conditions and forecasts, particularly in Richmond and Kings counties in New York, and Hunterdon, Mercer, Union and Middlesex counties in New Jersey and, to a lesser extent, eastern Pennsylvania. Accordingly, as with most financial institutions in the market area, the ultimate collectability of a substantial portion of the Company’s loan portfolio is susceptible to changes in conditions in the Company’s marketplace. In addition, future changes in laws and regulations could make it more difficult for the Company to collect all contractual amounts due on its loans.
 
In addition, various regulatory agencies, as an integral part of their examination process, periodically review the Company’s allowance for credit losses. Such agencies may require the Company to recognize additions to the allowance based on their judgments about information available to them at the time of their examination.
 
Prior to the adoption of ASU 2022-02, the Company classified certain loans as TDRs, which are loans where terms have been modified because of deterioration in the financial condition of the borrower. Modifications could include extension of the repayment terms of the loan, reduced interest rates, or forgiveness of accrued interest and/or principal. Once an obligation has been restructured because of such credit problems, it continues to be considered restructured until paid in full or, if the obligation yields a market rate (a rate equal to the rate the Company was willing to accept at the time of the restructuring for a new loan with comparable risk), until the year subsequent to the year in which the restructuring takes place, provided the borrower has performed under the modified terms for a consecutive six-month period. The Company records an impairment charge equal to the difference between the present value of estimated future cash flows under the restructured terms discounted at the original loan’s effective interest rate, or the underlying collateral value, less estimated costs to sell, if the loan is collateral dependent. Changes in present values attributable to the passage of time are recorded as a component of the provision for credit losses. Since the adoption of ASU 2022-02, the Company has ceased to recognize or measure new TDRs but those existing at December 31, 2022 remain until settled.
A loan is considered past due when it is not paid in accordance with its contractual terms. The accrual of income on loans, including impaired loans held-for-investment, and other loans in the process of foreclosure, is generally discontinued when a loan becomes 90 days or more delinquent, or sooner when certain factors indicate that the ultimate collection of principal and interest is in doubt. Loans on which the accrual of income has been discontinued are designated as non-accrual loans. All previously accrued interest is reversed against interest income, and income is recognized subsequently only in the period that cash is received, provided no principal payments are due and the remaining principal balance outstanding is deemed collectible. A non-accrual loan is not returned to accrual status until both principal and interest payments are brought current and factors indicating doubtful collection no longer exist, including performance by the borrower under the loan terms for a consecutive six-month period.
Federal Home Loan Bank ("FHLB") Stock Federal Home Loan Bank (“FHLB”) Stock
 
The Bank, as a member of the FHLB of New York (“FHLBNY”), is required to hold shares of capital stock in the FHLB as a condition to both becoming a member and engaging in certain transactions with the FHLB. The minimum investment requirement is determined by a “membership” investment component and an “activity-based” investment component. The membership investment component is the greater of 0.125% of the Bank’s mortgage-related assets, as defined by the FHLB, or $1,000. The activity-based investment component is equal to 4.5% of the Bank’s outstanding advances with the FHLB. The activity-based investment component also considers other transactions, including assets originated for or sold to the FHLB, and delivery commitments issued by the FHLB. The Company currently does not enter into these other types of transactions with the FHLB. 
    
On at least a quarterly basis, we perform an impairment analysis of FHLB stock in which we evaluate, among other things, (i) its earnings performance, including the significance of any decline in net assets of the FHLB as compared to the regulatory capital amount of the FHLB, (ii) the commitment by the FHLB to continue dividend payments, and (iii) the liquidity position of the FHLB. We did not consider our investment in FHLB stock to be impaired at December 31, 2024 or 2023.
Operating Leases Operating Leases
During the normal course of business, the Company enters into agreements, and at inception it determines if a particular agreement is a lease. The Company's operating lease agreements relate primarily to its corporate offices and bank branch offices. The agreements are recorded as operating lease right-of-use assets and operating lease liabilities on the consolidated balance sheets. Operating lease right-of-use assets and operating lease liabilities are recognized at the commencement date based on the present value of lease payments over the lease term, and represent the right to use an underlying asset for the lease term and the obligation to make lease payments arising from the lease. As the Company's leases do not provide an implicit rate, the Company uses its incremental borrowing rate in determining the present value of lease payments. The Company's lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the term of the lease.
Premises and Equipment, Net Premises and Equipment, Net
 
Premises and equipment, including leasehold improvements, are carried at cost, less accumulated depreciation and amortization. Depreciation and amortization of premises and equipment, including capital leases, are computed on a straight-line basis over the estimated useful lives of the related assets.  The estimated useful lives of significant classes of assets are generally as follows: buildings - forty years; furniture and equipment - five to seven years; and purchased computer software - three years. Leasehold improvements are amortized over the shorter of the term of the related lease or the estimated useful lives of the improvements. Major improvements are capitalized, while repairs and maintenance costs are charged to operations as incurred. Upon retirement or sale, any gain or loss is credited or charged to operations.
Bank Owned Life Insurance Bank-Owned Life Insurance
 
The Company has purchased bank-owned life insurance contracts to help fund its obligations for certain employee benefit costs. The Company’s investment in such insurance contracts has been reported on the consolidated balance sheets at their cash surrender values. Changes in cash surrender values and death benefit proceeds received in excess of the related cash surrender values are recorded as non-interest income.
Goodwill Goodwill
 
Intangible assets resulting from acquisitions under the purchase method of accounting consist of goodwill and other intangible assets.

Goodwill is allocated to Northfield’s reporting unit at the date goodwill is actually recorded. As of December 31, 2024, the carrying value of goodwill totaled $41.0 million. The Company qualitatively assessed the current economic environment, including macroeconomic conditions, industry and market conditions and overall financial performance of the Company, among others. After consideration of the results of the interim and annual 2024 impairment tests and the results for the year ended December 31, 2024, the Company determined that it was more-likely-than-not that the fair value of its reporting unit was above its book value as of December 31, 2024, which did not indicate impairment for our reporting unit, nor was our reporting unit at risk. The Company will test goodwill for impairment between annual test dates if an event occurs or circumstances change that would indicate the fair value of the reporting unit is below its carrying amount. The Company completed its annual impairment test as of December 31, 2024.
Income Taxes Income Taxes
 
Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to temporary differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply in the year in which those temporary differences are expected to be recovered or settled.  When applicable, deferred tax assets are reduced by a valuation allowance for any portions determined not likely to be realized. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date.
 
    Income tax benefits are recognized and measured based upon a two-step model: 1) a tax position must be more-likely-than-not to be sustained based solely on its technical merits in order to be recognized, and 2) the benefit is measured as the largest dollar amount of that position that is more-likely-than-not to be sustained upon settlement. The difference between the benefit recognized and the tax benefit claimed on a tax return is referred to as an unrecognized tax benefit. The Company records income tax-related interest and penalties, if applicable, within income tax expense.
Impairment of Long-Lived Assets Impairment of Long-Lived Assets
 
Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to future undiscounted (and without interest) net cash flows expected to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the fair value of the assets. Assets to be disposed of are reported at the lower of the carrying amount or fair value, less estimated costs to sell.
Securities Sold Under Agreements to Repurchase and Other Borrowings Securities Sold Under Agreements to Repurchase and Other Borrowings
 
The Company enters into sales of securities under agreements to repurchase (Repurchase Agreements) and collateral pledge agreements (Pledge Agreements) with selected dealers and banks. Such agreements are accounted for as secured financing transactions since the Company maintains effective control over the transferred or pledged securities and the transfer meets the other accounting and recognition criteria as required by the transfer and servicing topic of the FASB Accounting Standards. Obligations under these agreements are reflected as a liability on the consolidated balance sheets. Securities underlying the agreements are maintained at selected dealers and banks as collateral for each transaction executed and may be sold or pledged by the counterparty. Collateral underlying Repurchase Agreements that permit the counterparty to sell or pledge the underlying collateral is disclosed on the consolidated balance sheets as “encumbered.” The Company retains the right under all Repurchase Agreements and Pledge Agreements to substitute acceptable collateral throughout the terms of the agreement.
Comprehensive Income (Loss) Comprehensive Income (Loss)
 
Comprehensive income (loss) includes net income and the change in unrealized holding gains and losses on debt securities available-for-sale, change in actuarial gains and losses on other post-retirement benefits, and change in service cost on other postretirement benefits, net of taxes. Comprehensive income (loss) and its components is presented on the consolidated statements of comprehensive income.
Benefits Benefits
 
The Company sponsors a defined postretirement benefit plan that provides for medical and life insurance coverage to a limited number of retirees, as well as life insurance to all qualifying employees of the Company. The estimated cost of postretirement benefits earned is accrued during an individual’s estimated service period to the Company. The Company recognizes on its balance sheet the over-funded or under-funded status of a defined benefit postretirement plan measured as the difference between the fair value of plan assets and the benefit obligation at the end of our calendar year. The actuarial gains and losses and the prior service costs and credits that arise during the period are recognized as a component of other comprehensive income (loss), net of tax.    
 
Funds borrowed by the Employee Stock Ownership Plan (the “ESOP”) from the Company to purchase the Company’s common stock are being repaid from the Bank’s contributions over a period of up to 30 years. The Company’s common stock not yet allocated to participants is recorded as a reduction of stockholders’ equity at cost. The Company records compensation expense related to the ESOP at an amount equal to the shares committed to be released by the ESOP multiplied by the average fair value of our common stock during the reporting period.
 
The Company recognizes the grant-date fair value of stock-based awards issued to participants' as compensation cost on the consolidated statements of comprehensive income. The fair value of common stock awards is based on the closing price of our common stock as reported on the NASDAQ Stock Market on the grant date. The expense related to stock options is based on the estimated fair value of the options at the date of the grant using the Black-Scholes pricing model. The awards are fixed in nature and compensation cost related to stock-based awards is recognized on a straight-line basis over the requisite service periods. The Company accounts for forfeitures as they occur.
 
The Bank has a 401(k) plan covering substantially all employees.  Contributions to the plan are expensed as incurred.
Segment Reporting Segment Reporting
 
As a community-focused financial institution, substantially all of the Company’s operations involve the delivery of loan and deposit products to customers. Management makes operating decisions and assesses performance based on an ongoing review of these community banking operations, which constitute the Company’s only operating segment for financial reporting purposes.
Net Income per Common Share Net Income per Common Share
 
Net income per common share-basic is computed by dividing the net income available to common stockholders by the weighted average number of common shares outstanding, excluding unallocated ESOP shares and unearned common stock award shares. The weighted average common shares outstanding includes the average number of shares of common stock outstanding, including shares allocated or committed to be released ESOP shares. Net income per common share-diluted is computed using the same method as basic earnings per share, but reflects the potential dilution that could occur if stock options and unvested shares of restricted stock were exercised and converted into common stock.
When applying the treasury stock method we add the assumed proceeds from option exercises and the average unamortized compensation costs related to unvested shares of restricted stock and stock options. We then divided this sum by our average stock price for the period to calculate assumed shares repurchased. The excess of the number of shares issuable over the number of shares assumed to be repurchased is added to basic weighted average common shares to calculate diluted earnings per share.
Other Real Estate Owned Other Real Estate Owned
 
Assets acquired through loan foreclosure, or deed-in-lieu of, are held for sale and are initially recorded at estimated fair value, less estimated selling costs, when acquired, thus establishing a new cost basis. Costs after acquisition are generally expensed. If the estimated fair value of the asset subsequently declines, a write-down is recorded through other non-interest expense.
Advertising Costs Advertising Costs
Advertising costs are expensed in the period they are incurred.
Derivatives Derivatives
The Company records all derivatives on the Consolidated Balance Sheets at fair value. The Company has interest rate derivatives resulting from a service provided to certain qualified borrowers in a loan-related transaction and, therefore, are not used to manage interest rate risk in the Company’s assets or liabilities. As such, all changes in fair value of the Company’s interest rate derivatives are recognized directly in earnings. The fair value of the Company's derivatives is determined using discounted cash flow analysis using observable market-based inputs, which are considered Level 2 inputs.
Fair Value Measurement Fair Value Measurements
 
The following tables present the assets reported on the consolidated balance sheets at their estimated fair value as of December 31, 2024 and 2023, by level within the fair value hierarchy as required by the Fair Value Measurements and Disclosures Topic of the FASB Accounting Standards Codification. Financial assets and liabilities are classified in their entirety based on the level of input that is significant to the fair value measurement.  The fair value hierarchy is as follows:
Level 1 Inputs – Unadjusted quoted prices in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date.
Level 2 Inputs – Inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. These include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability (for example, interest rates, volatilities, prepayment speeds, loss severities, credit risks and default rates) or inputs that are derived principally from or corroborated by observable market data by correlations or other means.
Level 3 Inputs – Significant unobservable inputs that reflect the Company’s own assumptions that market participants would use in pricing the assets or liabilities.
Fair Value of Financial Instruments
Fair Value of Financial Instruments
 The FASB ASC Topic for Financial Instruments requires disclosure of the fair value of financial assets and financial liabilities, including those financial assets and financial liabilities that are not measured and reported at fair value on a recurring or non-recurring basis. The methodologies for estimating the fair value of financial assets and financial liabilities that are measured at fair value on a recurring or non-recurring basis are discussed above. The following methods and assumptions were used to estimate the fair value of other financial assets and financial liabilities not already discussed above:
(a)    Cash and Cash Equivalents
Cash and cash equivalents are short-term in nature with original maturities of three months or less; the carrying amount approximates fair value. Certificates of deposit having original terms of six-months or less; the carrying value generally approximates fair value. Certificates of deposit with an original maturity of six months or greater; the fair value is derived from discounted cash flows.
     (b)    Debt Securities (Held-to-Maturity)
The estimated fair values for substantially all of our securities are obtained from an independent, nationally recognized pricing service. The independent pricing service utilizes market prices of same or similar securities whenever such prices are available. Prices involving distressed sellers are not utilized in determining fair value. Where necessary, the independent third-party pricing service estimates fair value using models employing techniques such as discounted cash flow analysis. The assumptions used in these models typically include assumptions for interest rates, credit losses, and prepayments, utilizing market observable data where available.
(c)    Investments in Equity Securities at Net Asset Value Per Share
The Company uses net asset value as a practical expedient to record its investment in a private SBA Loan Fund since the shares in the fund are not publicly traded, do not have a readily determinable fair value, and the net asset value per share is calculated in a manner consistent with the measurement principles of an investment company.
(d)    FHLBNY Stock
FHLBNY stock is carried at cost, which approximates fair value, since this is the amount for which it could be redeemed and there is no active market for this stock. Due to restrictions placed on the transferability of FHLBNY stock it is not practical to determine the fair value as there is no active market for this stock.
(e)    Loans (Held-for-Investment)
Fair values are estimated for portfolios of loans with similar financial characteristics. Loans are segregated by type such as originated and purchased, and further segregated by residential mortgage, construction, land, multifamily, commercial and consumer. Each loan category is further segmented into amortizing and non-amortizing and fixed and adjustable rate interest terms and by performing and non-performing categories. The fair value of loans is estimated using a discounted cash flow analysis. The discount rates used to determine fair value use interest rate spreads that reflect factors such as liquidity, credit, and non-performance risk of the loans.
(f)    Loans (Held-for-Sale)
Held-for-sale loans are carried at the lower of aggregate cost or estimated fair value, less costs to sell, and therefore fair value is equal to carrying value.
 (g)    Deposits
 The fair value of deposits with no stated maturity, such as interest and non-interest-bearing demand deposits, savings, NOW and money market accounts, is equal to the amount payable on demand. The fair value of certificates of deposit is based on the discounted value of contractual cash flows. The discount rate is estimated using the rates currently offered for deposits of similar remaining maturities.
 
(h)    Commitments to Extend Credit and Standby Letters of Credit
 
The fair value of commitments to extend credit and standby letters of credit is estimated using the fees currently charged to enter into similar agreements, taking into account 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 value of off-balance-sheet commitments is insignificant and therefore not included in the following table.

(i)    Borrowings

The fair value of borrowed funds is estimated by discounting future cash flows based on rates currently available for debt with similar terms and remaining maturity.

(j)    Advance Payments by Borrowers for Taxes and Insurance
 
Advance payments by borrowers for taxes and insurance have no stated maturity; the fair value is equal to the amount currently payable.

(k)    Derivatives

The fair value of the Company's derivatives is determined using discounted cash flow analysis using observable market-based inputs, which are considered Level 2 inputs.
