Organization, Consolidation and Presentation of Financial Statements [Abstract]
Consolidated Financial Statements	Consolidated Financial Statements Basis of Presentation The consolidated financial statements are comprised of the accounts of Northfield Bancorp, Inc. and its wholly owned subsidiaries, Northfield Investments, Inc. and Northfield Bank (the “Bank”), and the Bank’s wholly-owned subsidiaries, NSB Services Corp. and NSB Realty Trust (collectively the “Company”). All significant intercompany accounts and transactions have been eliminated in consolidation. In the opinion of management, all adjustments (consisting solely of normal and recurring adjustments) necessary for the fair presentation of the consolidated balance sheets and the consolidated statements of comprehensive income for the unaudited periods presented have been included. The results of operations and other data presented for the three and nine months ended September 30, 2022 are not necessarily indicative of the results of operations that may be expected for the year ending December 31, 2022 or for any other period. Whenever necessary, certain prior year amounts are reclassified to conform to the current year presentation. In preparing the unaudited consolidated financial statements in conformity with U.S. generally accepted accounting principles (“U.S. GAAP”), management has made estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the consolidated balance sheets and for the periods indicated in the consolidated statements of comprehensive income. Material estimates that are particularly susceptible to change are: the allowance for credit losses, estimated cash flows of our purchased credit-deteriorated (“PCD”, or, previously, purchased credit-impaired “PCI”) loans and the valuation allowance against deferred tax assets. Estimates and assumptions are reviewed periodically and the effects of revisions are reflected in the consolidated financial statements in the period they are deemed necessary. While management uses its best judgment, actual amounts or results could differ significantly from those estimates.

Certain debt 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 September 30, 2022 and December 31, 2021, the fair value of debt securities available-for-sale that were pledged to secure borrowings and deposits was $552.5 million and $522.1 million, respectively. For the three months ended September 30, 2022, the Company had no sales of debt securities available-for-sale, and no gross realized gains or losses. For the nine months ended September 30, 2022, the Company had gross proceeds of $41.5 million on sales and calls of debt securities available-for-sale, with gross realized gains of $264,000 related to the sales of securities and no gross realized losses. For the three months ended September 30, 2021, the Company had gross proceeds of $112.5 million on sales of debt securities available-for-sale, with gross realized gains of $370,000 and no gross realized losses. For the nine months ended September 30, 2021, the Company had gross proceeds of $208.0 million on sales and calls of debt securities available-for-sale, with gross realized gains of $976,000 related to sales of securities and no gross realized losses. The Company recognized net losses of $426,000 and $2.8 million on its trading securities portfolio during the three and nine months ended September 30, 2022, respectively. During the three and nine months ended September 30, 2021, the Company recognized net losses of $75,000 and net gains of $1.1 million, respectively, on its trading securities portfolio. Gross unrealized losses on mortgage-backed securities and other debt securities available-for-sale, and the estimated fair value of the related securities, aggregated by security category and length of time that individual securities have been in a continuous unrealized loss position, at September 30, 2022 and December 31, 2021, were as follows (in thousands): September 30, 2022 Less than 12 months 12 months or more Total Unrealized Estimated Unrealized Estimated Unrealized Estimated losses fair value losses fair value losses fair value U.S. Government agency securities $ (4,174) $ 70,826 $ (136) $ 1,014 $ (4,310) $ 71,840 Mortgage-backed securities: Pass-through certificates: GSE (35,357) 353,695 (12,556) 100,734 (47,913) 454,429 REMICs: GSE (7,643) 199,686 (6,890) 82,483 (14,533) 282,169 Other debt securities: Corporate bonds (4,311) 129,617 (3,798) 46,201 (8,109) 175,818 Total $ (51,485) $ 753,824 $ (23,380) $ 230,432 $ (74,865) $ 984,256 December 31, 2021 Less than 12 months 12 months or more Total Unrealized Estimated Unrealized Estimated Unrealized Estimated losses fair value losses fair value losses fair value U.S. Government agency securities $ — $ — $ (54) $ 2,290 $ (54) $ 2,290 Mortgage-backed securities: Pass-through certificates: GSE (2,543) 417,291 (318) 14,625 (2,861) 431,916 REMICs: GSE (1,350) 125,725 (94) 4,413 (1,444) 130,138 Other debt securities: Corporate bonds (744) 146,853 — — (744) 146,853 Total $ (4,637) $ 689,869 $ (466) $ 21,328 $ (5,103) $ 711,197 The Company held 23 pass-through mortgage-backed securities issued or guaranteed by GSEs, 31 REMIC mortgage-backed securities issued or guaranteed by GSEs, six corporate bonds, and one U.S. Government agency security that were in a continuous unrealized loss position of twelve months or greater at September 30, 2022. There were 102 pass-through mortgage-backed securities issued or guaranteed by GSEs, 55 REMIC mortgage-backed securities issued or guaranteed by GSEs, 23 corporate bonds and four U.S. Government agency securities that were in an unrealized loss position of less than twelve months at September 30, 2022. All securities referred to above were rated investment grade at September 30, 2022. 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 all 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 as of September 30, 2022 or December 31, 2021. 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 $2.4 million and $2.5 million, respectively, at September 30, 2022 and December 31, 2021 was reported in accrued interest receivable on the consolidated balance sheets.

There were no sales of held-to-maturity securities for the nine months ended September 30, 2022 or September 30, 2021. At September 30, 2022 and December 31, 2021, debt securities held-to-maturity with a carrying value of $2.0 million and $2.1 million, respectively, were pledged to secure borrowings and deposits. Gross unrealized losses on mortgage-backed securities held-to-maturity, and the estimated fair value of the related securities, aggregated by security category and length of time that individual securities have been in a continuous unrealized loss position at September 30, 2022 were as follows (in thousands): September 30, 2022 Less than 12 months 12 months or more Total Unrealized Estimated Unrealized Estimated Unrealized Estimated losses fair value losses fair value losses fair value Mortgage-backed securities: Pass-through certificates: GSE $ (462) $ 4,110 $ — $ — $ (462) $ 4,110 Total $ (462) $ 4,110 $ — $ — $ (462) $ 4,110 The Company held six pass-through mortgage-backed debt securities held-to-maturity issued or guaranteed by GSEs that were in an unrealized loss position of less than twelve months at September 30, 2022 and no held-to-maturity securities in an unrealized loss position of greater than twelve months at September 30, 2022. There were no held-to-maturity securities in an unrealized loss position at December 31, 2021. 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 $14,000 and $15,000, respectively, at September 30, 2022 and December 31, 2021 was reported in accrued interest receivable on the consolidated balance sheets.

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 $2.4 million and $2.5 million, respectively, at September 30, 2022 and December 31, 2021 was reported in accrued interest receivable on the consolidated balance sheets.

Receivables [Abstract]
Loans	Loans The following table summarizes the Company’s loans held-for-investment (in thousands): September 30, December 31, 2022 2021 Real estate loans: Multifamily $ 2,856,322 $ 2,518,065 Commercial mortgage 889,390 808,597 One-to-four family residential mortgage 176,251 183,665 Home equity and lines of credit 146,546 109,956 Construction and land 21,668 27,495 Total real estate loans 4,090,177 3,647,778 Commercial and industrial loans (1) 141,873 141,005 Other loans 2,158 2,015 Total commercial and industrial and other loans 144,031 143,020 Loans held-for-investment, net (excluding PCD) 4,234,208 3,790,798 PCD loans 11,973 15,819 Total loans held-for-investment, net 4,246,181 3,806,617 Allowance for credit losses (41,883) (38,973) Net loans held-for-investment $ 4,204,298 $ 3,767,644 (1) Included in commercial and industrial loans at September 30, 2022 and December 31, 2021 are Payment Protection Program ("PPP") loans totaling $5.5 million and $40.5 million, respectively. The Company had $504,000 of loans held-for-sale at September 30, 2022 and no loans held-for-sale at December 31, 2021. 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 $12.0 million at September 30, 2022, as compared to $15.8 million at December 31, 2021. The majority of the PCD loan balance is attributable to loans acquired as part of a Federal Deposit Insurance Corporation-assisted transaction. At September 30, 2022, PCD loans consisted of approximately 10% home equity loans, 28% commercial real estate loans, 51% commercial and industrial loans, and 12% in one-to-four family residential loans. At December 31, 2021, PCD loans consisted of approximately 16% one-to-four family residential loans, 25% commercial real estate loans, 48% commercial and industrial loans, and 11% in construction and land and 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 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. Loan-to-value ( “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. 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. 1. Strong 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 recorded investment of these non-accrual loans was $9.8 million and $7.6 million at September 30, 2022, and December 31, 2021, 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 troubled debt restructurings ("TDRs") are individually evaluated. The non-accrual amounts included in loans individually evaluated for impairment were $5.3 million and $4.2 million at September 30, 2022, and December 31, 2021, respectively. Loans on non-accrual status with principal balances less than $500,000, and therefore not meeting the Company's definition of an impaired loan, amounted to $4.5 million at September 30, 2022, and $3.4 million at December 31, 2021. Loans past due 90 days or more and still accruing interest were $54,000 and $384,000 at September 30, 2022 and December 31, 2021, respectively, and consisted of loans that are well secured and in the process of collection.

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. Collateral values are generally based on appraisals which are adjusted for changes in market indices. As of September 30, 2022 and December 31, 2021, the Company had $7.8 million and $7.4 million of collateral-dependent impaired loans, respectively. The collateral-dependent loans at September 30, 2022 consisted of $5.1 million of commercial real estate loans, $2.3 million of multifamily loans, and $343,000 of one-to-four family residential loans. For the nine months ended September 30, 2022, there was no significant deterioration or changes in the collateral securing these loans. Troubled Debt Restructured Loan There were no loans modified as a TDR during the three or nine months ended September 30, 2022. The following table summarizes loans that were modified in a TDR during the nine months ended September 30, 2021: Nine Months Ended September 30, 2021 Number of Relationships Pre-Modification Outstanding Recorded Investment Post-Modification Outstanding Recorded Investment (1) (in thousands) Troubled Debt Restructurings Commercial and industrial 1 $ 75 75 Total Troubled Debt Restructurings 1 $ 75 $ 75 (1) Amounts are at time of modification There were three commercial and industrial loans to one borrower modified as a TDR during the nine months ended September 30, 2021, which were modified to reduce the interest rate, extend the maturity date, and restructure payment terms of the loans. In response to the novel Coronavirus Disease 2019 ("COVID-19") pandemic and its economic impact to customers, a short-term modification program that complied with Section 4013 of the CARES Act and the Interagency Statement on Loan Modifications and Reporting for Financial Institutions Working with Customers Affected by the Coronavirus was implemented to provide temporary payment relief to those borrowers directly impacted by COVID-19. The program allowed for deferral of payments for 90 days, which may extend for an additional 90 day period, with modifications in the form of payment deferrals, fee waivers, extensions of repayment terms, or other delays in payment. As of September 30, 2022, substantially all of the borrowers who had requested relief have returned to contractual payments. At September 30, 2022 and December 31, 2021, the Company had TDRs of $7.2 million and $9.0 million, respectively. Management classifies all TDRs as loans individually evaluated for impairment. 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 impaired 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 under TDRs which are not collateral-dependent is inherently subjective and requires, among other things, an evaluation of the borrower’s current and projected financial condition. Actual results may be significantly different than our projections and our established allowance for credit losses on these loans, which could have a material effect on our financial results. At September 30, 2022 and September 30, 2021, there were no restructured TDRs during the preceding twelve months that subsequently defaulted.

Allowance for Credit Losses (“ACL”) on Loans	9 Months Ended

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”). Management utilizes five different Moody's scenarios so as to incorporate uncertainties related to the economic environment arising from the COVID-19 pandemic. 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 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 impaired 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 under troubled debt restructurings which are not collateral-dependent is inherently subjective and requires, among other things, an evaluation of the borrower’s current and projected financial condition. Actual results may be significantly different than our projections and our established allowance for credit losses on these loans, which could have a material effect on our financial results. Individually impaired loans that have no impairment losses are not considered for collective allowances described earlier. At September 30, 2022 and December 31, 2021, the ACL for loans individually evaluated for impairment was $45,600 and $30,200, respectively. 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 on books already). 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 Current Expected Credit Losses (“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 three and nine months ended September 30, 2022, and September 30, 2021 (in thousands): Three Months Ended September 30, Nine Months Ended September 30, 2022 2021 2022 2021 Balance at beginning of period $ 2,480 $ 1,808 $ 1,852 $ 1,545 (Benefit)/provision for credit losses (1,888) 265 (1,260) 528 Balance at end of period $ 592 $ 2,073 $ 592 $ 2,073 The following tables set forth activity in our allowance for credit losses on loans, by loan type, as of, and for the three and nine months ended September 30, 2022, and September 30, 2021 (in thousands): Three Months Ended September 30, 2022 Real Estate Commercial (1) One-to-Four Family Home Equity and Lines of Credit Construction and Land Commercial and Industrial Other Total Loans (excluding PCD) PCD Total Allowance for credit losses: Beginning balance $ 28,065 $ 3,005 $ 802 $ 285 $ 2,705 $ 11 $ 34,873 $ 4,158 $ 39,031 Charge-offs — — — — — — — (75) (75) Recoveries 4 7 19 — 12 4 46 178 224 Provisions (credit) 2,117 553 53 (10) 238 (9) 2,942 (239) 2,703 Ending balance $ 30,186 $ 3,565 $ 874 $ 275 $ 2,955 $ 6 $ 37,861 $ 4,022 $ 41,883 Three Months Ended September 30, 2021 Real Estate Commercial (1) One-to-Four Family Home Equity and Lines of Credit Construction and Land Commercial and Industrial Other Total Loans (excluding PCD) PCD Total Allowance for credit losses: Beginning balance 26,540 4,610 663 259 2,594 7 34,673 4,820 39,493 Charge-offs — — — — (541) (3) (544) — (544) Recoveries — 27 25 — 6 3 61 — 61 Provisions (credit) (297) (230) (46) (69) 542 (1) (101) (47) (148) Ending balance $ 26,243 $ 4,407 $ 642 $ 190 $ 2,601 $ 6 $ 34,089 $ 4,773 $ 38,862 (1) Commercial includes commercial real estate loans collateralized by owner-occupied, non-owner occupied, and multifamily properties.

The allowance for credit losses on loans increased to $41.9 million at September 30, 2022, compared to $39.0 million as of December 31, 2021, primarily due to growth in the loan portfolio and a declining macroeconomic outlook. The following tables detail the amount of loans receivable held-for-investment, net of deferred loan fees and costs, that are evaluated, individually and collectively, for impairment, and the related portion of the allowance for credit losses that is allocated to each loan portfolio segment, at September 30, 2022 and December 31, 2021 (in thousands): September 30, 2022 Real Estate Commercial (1) One-to-Four Family Home Equity and Lines of Credit Construction and Land Commercial and Industrial Other Total Loans (excluding PCD) PCD Total Allowance for credit losses: Ending balance: individually evaluated for impairment $ 25 $ — $ 3 $ — $ 18 $ — $ 46 $ — $ 46 Ending balance: collectively evaluated for impairment 30,160 3,565 871 275 2,938 6 37,815 — 37,815 Ending balance: PCD loans evaluated for impairment (2) — — — — — — — 4,022 4,022 Loans, net: Ending balance $ 3,745,712 $ 176,251 $ 146,546 $ 21,668 $ 141,873 $ 2,158 $ 4,234,208 $ 11,973 $ 4,246,181 Ending balance: individually evaluated for impairment 8,566 680 27 — 97 9,370 — 9,370 Ending balance: collectively evaluated for impairment 3,737,146 175,571 146,519 21,668 136,269 2,158 4,219,331 — 4,219,331 Ending balance: PCD loans evaluated for impairment (2) — — — — — — — 11,973 11,973 PPP loans not evaluated for impairment (3) — — — — 5,507 — 5,507 — 5,507 December 31, 2021 Real Estate Commercial (1) One-to-Four Family Home Equity and Lines of Credit Construction and Land Commercial and Industrial Other Total Loans (excluding PCD) PCD Total Allowance for credit losses: Ending balance: individually evaluated for impairment $ 25 $ 2 $ 2 $ — $ 1 $ — $ 30 $ — $ 30 Ending balance: collectively evaluated for impairment 26,760 3,543 558 169 3,172 9 34,211 — 34,211 Ending balance: PCD loans evaluated for impairment (2) — — — — — — — 4,732 4,732 Loans, net: Ending balance $ 3,326,662 $ 183,665 $ 109,956 $ 27,495 $ 141,005 $ 2,015 $ 3,790,798 $ 15,819 $ 3,806,617 Ending balance: individually evaluated for impairment 8,352 1,562 38 — 34 — 9,986 — 9,986 Ending balance: collectively evaluated for impairment 3,318,310 182,103 109,918 27,495 100,454 2,015 3,740,295 — 3,740,295 Ending balance: PCD loans evaluated for impairment (2) — — — — — — — 15,819 15,819 PPP loans not evaluated for impairment (3) — — — — 40,517 — 40,517 — 40,517 (1) Commercial includes commercial real estate loans collateralized by owner-occupied, non-owner occupied, and multifamily properties. (2) Upon adoption of CECL, the Company elected to maintain pools of PCD loans that were previously accounted for under ASC 310-30, and will continue to evaluate PCD loans under this guidance. (3) PPP loans are guaranteed by the SBA and therefore excluded from the allowance for credit losses.

Debt Disclosure [Abstract]
Subordinated Debt	Subordinated Debt On June 17, 2022, the Company issued $62.0 million in aggregate principal amount of fixed-to-floating subordinated notes (the “Notes”) to certain institutional investors. The Notes mature on June 30, 2032, unless redeemed earlier. The Notes initially bear interest, payable semi-annually in arrears, at a fixed rate of 5.00% per annum until June 30, 2027. Beginning June 30, 2027 and until maturity or redemption, the interest rate applicable to the outstanding principal amount of the Notes due will reset quarterly to an interest rate per annum equal to the then current three-month Secured Overnight Financing Rate plus 200 basis points, payable quarterly in arrears. The Company has the option to redeem the Notes, at par and in whole or in part, beginning on June 30, 2027 and to redeem the Notes at any time in whole upon certain other events. Any redemption of the Notes will be subject to prior regulatory approval to the extent required. Debt issuance costs totaled $1.1 million and are being amortized to maturity. The Company recognized amortization expense of $56,000 for the three months ended September 30, 2022. The Company intends to use the net proceeds from the issuance of the Notes for general corporate purposes, including to fund potential repurchases of shares of the Company’s outstanding common stock. On August 17, 2022, the SEC declared effective a Registration Statement on Form S-4 with respect to the exchange of the Notes for publicly registered subordinated notes with the same terms as the Notes. On September 16, 2022, the Company completed the exchange of the Notes for the publicly registered subordinated notes. All of the Notes were exchanged by the holders thereof.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements The following tables present the assets reported on the consolidated balance sheets at their estimated fair value as of September 30, 2022, and December 31, 2021, by level within the fair value hierarchy as required by the Fair Value Measurements and Disclosures Topic of the FASB ASC. 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 methods of determining the fair value of assets and liabilities presented in this note are consistent with our methodologies disclosed in Note 16 to the Consolidated Financial Statements of the Company’s 2021 Annual Report on Form 10-K.

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 nine months ended September 30, 2022 or September 30, 2021. 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 September 30, 2022 and December 31, 2021, the Company had loans individually evaluated for impairment (excluding PCD loans) with outstanding principal balances of $4.3 million and $5.8 million, respectively, which were recorded at their estimated fair value of $2.8 million and $3.8 million, respectively. The Company recorded a net increase in the specific reserve for impaired loans of $15,400 and a net decrease of $42,000 for the nine months ended September 30, 2022 and September 30, 2021, respectively. Net charge-offs of $345,000 and $2.9 million were recorded for the nine months ended September 30, 2022 and September 30, 2021, 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 and TDRs. Other Real Estate Owned: At September 30, 2022, the Company had no assets acquired through foreclosure. At December 31, 2021, the Company had other real estate owned of approximately $100,000, recorded at estimated fair value, less estimated selling costs when acquired, thus establishing a new cost basis. The property was located in New Jersey and was sold during the second quarter of 2022 for a small gain. Estimated fair value is generally based on independent appraisals. These appraisals include adjustments to comparable assets based on the appraisers’ market knowledge and experience, and are considered Level 3 inputs. When an asset is acquired, the excess of the loan balance over fair value, less estimated selling costs, is charged to the allowance for credit losses. If the estimated fair value of the asset declines, a write-down is recorded through non-interest expense. The valuation of foreclosed assets is subjective in nature and may be adjusted in the future because of changes in the economic conditions. In addition, the Company may be required, from time to time, to measure the fair value of certain other financial assets on a nonrecurring 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) Federal Home Loan Bank of New York Stock The fair value for Federal Home Loan Bank of New York ("FHLBNY") stock is its carrying value, since this is the amount for which it could be redeemed and 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 September 30, 2022 and December 31, 2021, are presented in the following tables (in thousands): September 30, 2022 Estimated Fair Value Carrying Value Level 1 Level 2 Level 3 Total Financial assets: Cash and cash equivalents $ 70,665 $ 70,665 $ — $ — $ 70,665 Trading securities 10,074 10,074 — — 10,074 Debt securities available-for-sale 1,002,231 — 1,002,231 — 1,002,231 Debt securities held-to-maturity 4,572 — 4,110 — 4,110 Equity securities (1) 1,023 1,023 — — 1,023 FHLBNY stock, at cost 22,417 — 22,417 — 22,417 Net loans held-for-investment 4,204,298 — — 4,025,778 4,025,778 Derivative assets 5,541 — 5,541 — 5,541 Financial liabilities: Deposits $ 4,404,159 $ — $ 4,404,974 $ — $ 4,404,974 Borrowed funds 407,678 — 387,749 — 387,749 Subordinated debentures 60,940 — 54,547 — 54,547 Advance payments by borrowers for taxes and insurance 26,137 — 26,137 — 26,137 Derivative liabilities 5,541 — 5,541 — 5,541 (1) Excludes investment measured at net asset value of $7.5 million at September 30, 2022, which has not been classified in the fair value hierarchy.

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.

Earnings Per Share [Abstract]
Earnings Per Share	Earnings Per Share Basic earnings per share is computed by dividing net income available to common stockholders by the weighted average number of shares outstanding during the period. For purposes of calculating basic earnings per share, weighted average common shares outstanding excludes unallocated employee stock ownership plan (“ESOP”) shares that have not been committed for release and unvested restricted stock and performance-based restricted stock units. Diluted earnings per share is computed using the same method as basic earnings per share, but reflects the potential dilution that could occur if stock options were exercised and converted into common stock and unvested shares of restricted stock and performance-based restricted stock units vested. These potentially dilutive shares are then included in the weighted average number of shares outstanding for the period using the treasury stock method. When applying the treasury stock method we added the assumed proceeds from option exercises and the average unamortized compensation costs related to unvested shares of restricted stock, performance-based restricted stock units 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. The following is a summary of the Company’s earnings per share calculations and reconciliation of basic to diluted earnings per share for the periods indicated (in thousands, except per share data): Three Months Ended September 30, Nine Months Ended September 30, 2022 2021 2022 2021 Net income available to common stockholders $ 16,979 $ 16,080 $ 46,980 $ 54,551 Weighted average shares outstanding-basic 46,047,104 48,095,473 46,486,086 48,838,396 Effect of non-vested restricted stock and stock, performance-based restricted stock units and options outstanding 189,557 390,623 170,997 298,641 Weighted average shares outstanding-diluted 46,236,661 48,486,096 46,657,083 49,137,037 Earnings per share-basic $ 0.37 $ 0.33 $ 1.01 $ 1.12 Earnings per share-diluted $ 0.37 $ 0.33 $ 1.01 $ 1.11 Anti-dilutive shares 738,103 125,744 978,187 417,955

Leases [Abstract]
Leases	Leases The Company’s leases primarily relate to real estate property for branches and office space with terms extending from six months up to 32.8 years. At September 30, 2022, 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 At September 30, 2022, the Company’s operating lease right-of-use assets and operating lease liabilities included on the consolidated balance sheet were $35.4 million and $41.1 million, respectively. At December 31, 2021, the Company’s operating lease right-of-use assets and operating lease liabilities included on the consolidated balance sheet were $33.9 million and $39.9 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 three and nine months ended September 30, 2022, and September 30, 2021 is as follows (dollars in thousands): Three Months Ended September 30, Nine Months Ended September 30, 2022 2021 2022 2021 Operating lease cost $ 1,499 $ 1,409 $ 4,489 $ 4,317 Variable lease cost 964 974 2,792 3,219 Net lease cost $ 2,463 $ 2,383 $ 7,281 $ 7,536 Cash paid for amounts included in measurement of operating lease liabilities $ 1,590 $ 1,568 $ 4,751 $ 4,967 Right-of-use assets obtained in exchange for new operating lease liabilities $ — $ 1,596 $ 4,983 $ 1,596 Weighted average remaining lease term 11.29 years 11.89 years Weighted average discount rate 3.53 % 3.55 % The following table summarizes lease payment obligations for each of the next five years and thereafter in addition to a reconcilement to the Company's current lease liability (in thousands): Year Amount 2022 $ 1,596 2023 6,490 2024 6,069 2025 5,729 2026 4,967 Thereafter 26,564 Total lease payments 51,415 Less: imputed interest 10,364 Present value of lease liabilities $ 41,051 As of September 30, 2022, the Company had not entered into any leases that have not yet commenced.

Revenue from Contract with Customer [Abstract]
Revenue Recognition	Revenue Recognition The Company records revenue from contracts with customers in accordance with Accounting Standards Update 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, overdraft 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 three and nine months ended September 30, 2022, other income primarily included rental income from subleasing one of the Company's branches to a third party and loan servicing fees. For the three and nine months ended September 30, 2021, other income primarily included rental income from subleasing one of the Company's branches to a third party and loan servicing fees. The following table summarizes non-interest income for the periods indicated (in thousands): Three Months Ended September 30, Nine Months Ended September 30, 2022 2021 2022 2021 Fees and service charges for customer services: Service charges $ 907 $ 763 $ 2,461 $ 2,173 ATM and card interchange fees 487 515 1,433 1,397 Investment fees 106 92 312 324 Total fees and service charges for customer services 1,500 1,370 4,206 3,894 Income on bank-owned life insurance (1) 861 862 2,548 2,567 Gains on available-for-sale debt securities, net (1) — 370 264 976 (Losses)/gains on trading securities, net (1) (426) (75) (2,791) 1,096 Gains on sales of loans (1) 273 — 273 1,401 Other 78 101 264 246 Total non-interest income $ 2,286 $ 2,628 $ 4,764 $ 10,180 (1) Not in scope of Topic 606

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 September 30, 2022, the Company had seven interest rate swaps with a notional amount of $37.3 million. At December 31, 2021, the Company had seven interest rate swaps with a notional amount of $38.1 million. The Company recorded no fee income related to these swaps for the three and nine months ended September 30, 2022 and 2021. The table below presents the fair value of the derivatives as well as their location on the consolidated balance sheets (in thousands): Fair Value Balance Sheet Location September 30, 2022 December 31, 2021 Other assets $ 5,541 $ 923 Other liabilities 5,541 925

Consolidated Financial Statem_2

Consolidated Financial Statements (Policies)	9 Months Ended
	Sep. 30, 2022
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	The consolidated financial statements are comprised of the accounts of Northfield Bancorp, Inc. and its wholly owned subsidiaries, Northfield Investments, Inc. and Northfield Bank (the “Bank”), and the Bank’s wholly-owned subsidiaries, NSB Services Corp. and NSB Realty Trust (collectively the “Company”). All significant intercompany accounts and transactions have been eliminated in consolidation. In the opinion of management, all adjustments (consisting solely of normal and recurring adjustments) necessary for the fair presentation of the consolidated balance sheets and the consolidated statements of comprehensive income for the unaudited periods presented have been included. The results of operations and other data presented for the three and nine months ended September 30, 2022 are not necessarily indicative of the results of operations that may be expected for the year ending December 31, 2022 or for any other period. Whenever necessary, certain prior year amounts are reclassified to conform to the current year presentation. In preparing the unaudited consolidated financial statements in conformity with U.S. generally accepted accounting principles (“U.S. GAAP”), management has made estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the consolidated balance sheets and for the periods indicated in the consolidated statements of comprehensive income. Material estimates that are particularly susceptible to change are: the allowance for credit losses, estimated cash flows of our purchased credit-deteriorated (“PCD”, or, previously, purchased credit-impaired “PCI”) loans and the valuation allowance against deferred tax assets. Estimates and assumptions are reviewed periodically and the effects of revisions are reflected in the consolidated financial statements in the period they are deemed necessary. While management uses its best judgment, actual amounts or results could differ significantly from those estimates.
Fair Value Measurements	The following tables present the assets reported on the consolidated balance sheets at their estimated fair value as of September 30, 2022, and December 31, 2021, by level within the fair value hierarchy as required by the Fair Value Measurements and Disclosures Topic of the FASB ASC. 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	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) Federal Home Loan Bank of New York Stock The fair value for Federal Home Loan Bank of New York ("FHLBNY") stock is its carrying value, since this is the amount for which it could be redeemed and 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.
Earnings Per Share	Basic earnings per share is computed by dividing net income available to common stockholders by the weighted average number of shares outstanding during the period. For purposes of calculating basic earnings per share, weighted average common shares outstanding excludes unallocated employee stock ownership plan (“ESOP”) shares that have not been committed for release and unvested restricted stock and performance-based restricted stock units.Diluted earnings per share is computed using the same method as basic earnings per share, but reflects the potential dilution that could occur if stock options were exercised and converted into common stock and unvested shares of restricted stock and performance-based restricted stock units vested. These potentially dilutive shares are then included in the weighted average number of shares outstanding for the period using the treasury stock method. When applying the treasury stock method we added the assumed proceeds from option exercises and the average unamortized compensation costs related to unvested shares of restricted stock, performance-based restricted stock units 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.
