Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies A. Basis of Financial Statement Presentation The accompanying unaudited consolidated financial statements include the accounts of Provident Financial Services, Inc. (the "Company") and its wholly owned subsidiary, Provident Bank (the “Bank") and its wholly owned subsidiaries. In preparing the interim unaudited 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 consolidated statements of financial condition and the consolidated statements of income for the periods presented. Actual results could differ from these estimates. The allowance for credit losses is a material estimate that is particularly susceptible to near-term change. The interim unaudited consolidated financial statements reflect all normal and recurring adjustments, which are, in the opinion of management, considered necessary for a fair presentation of the financial condition and results of operations for the periods presented. The results of operations for the three months ended March 31, 2024 are not necessarily indicative of the results of operations that may be expected for all of 2024. Certain information and note disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) have been condensed or omitted pursuant to the rules and regulations of the Securities and Exchange Commission. Additionally, certain comparative balances on the interim unaudited consolidated financial statements have been reclassified to conform to the current year’s presentation. These unaudited consolidated financial statements should be read in conjunction with the December 31, 2023 Annual Report to Stockholders on Form 10-K. B. Earnings Per Share The following is a reconciliation of the numerators and denominators of the basic and diluted earnings per share calculations for the three months ended March 31, 2024 and 2023 (dollars in thousands, except per share amounts): Three months ended March 31, 2024 2023 Net Weighted Per Net Weighted Per Net income $ 32,082 $ 40,536 Basic earnings per share: Income available to common stockholders $ 32,082 75,260,029 $ 0.43 $ 40,536 74,645,336 $ 0.54 Dilutive shares 15,631 57,191 Diluted earnings per share: Income available to common stockholders $ 32,082 75,275,660 $ 0.43 $ 40,536 74,702,527 $ 0.54 Anti-dilutive stock options and awards as of March 31, 2024 and 2023, totaling 1.4 million shares and 984,877 shares, respectively, were excluded from the earnings per share calculations. C. Loans Receivable and Allowance for Credit Losses The impact of utilizing the current expected credit loss ("CECL") methodology approach to calculate the allowance for credit losses on loans is significantly influenced by the composition, characteristics and quality of the Company’s loan portfolio, as well as the prevailing economic conditions and forecast utilized. Material changes to these and other relevant factors may result in greater volatility to the allowance for credit losses, and therefore, greater volatility to the Company’s reported earnings. For the three months ended March 31, 2024, an increase in specific reserves on impaired credits, partially offset by an improved economic forecast for the current quarter within our CECL model, led to a provisions charge for credit losses, while a decrease in loans approved and awaiting closing led to a provision benefit for credit losses on off-balance sheet credit exposures. See Notes 4 and 10 to the Consolidated Financial Statements for more information on the allowance for credit losses on loans and off-balance sheet credit exposures. D. Goodwill

Investment Securities	Investment Securities As of March 31, 2024, the Company had $1.67 billion and $354.7 million in available for sale debt securities and held to maturity debt securities, respectively. Many factors, including lack of liquidity in the secondary market for certain securities, variations in pricing information, changes in interest rates, regulatory actions, changes in the business environment or any changes in the competitive marketplace, could have an adverse effect on the Company’s investment portfolio. The total number of available for sale and held to maturity debt securities in an unrealized loss position as of March 31, 2024 totaled 954, compared with 808 as of December 31, 2023. The increase in the number of securities in an unrealized loss position as of March 31, 2024 was due to higher current market interest rates compared to rates as of December 31, 2023.

The amortized cost and fair value of available for sale debt securities as of March 31, 2024, by contractual maturity, are shown below (in thousands).

Accrued interest on held to maturity debt securities, which is excluded from the amortized cost, totaled $2.4 million and $3.1 million as of March 31, 2024 and December 31, 2023, respectively, and is presented within total accrued interest receivable on the consolidated statements of financial condition. The Company generally purchases securities for long-term investment purposes, and differences between amortized cost and fair value may fluctuate during the investment period. There were no sales of securities from the held to maturity debt securities portfolio for the three months ended March 31, 2024 and 2023. For the three months ended March 31, 2024, proceeds from calls on securities in the held to maturity debt securities portfolio totaled $1.2 million. As to these calls on securities, for the three months ended March 31, 2024, there were no gross gains and gross losses of $1,200. For the three months ended March 31, 2023, proceeds from calls on securities in the held to maturity debt securities portfolio totaled $3.1 million with no gross gains and gross losses of $5,000. The amortized cost and fair value of investment securities in the held to maturity debt securities portfolio as of March 31, 2024 by contractual maturity are shown below (in thousands). Expected maturities may differ from contractual maturities due to prepayment or early call privileges of the issuer.

The number of held to maturity debt securities in an unrealized loss position as of March 31, 2024 totaled 520, compared with 372 as of December 31, 2023. The increase in the number of securities in an unrealized loss position as of March 31, 2024, was due to higher current market interest rates compared to rates as of December 31, 2023. Management measures expected credit losses on held to maturity debt securities on a collective basis by security type. Management classifies the held to maturity debt securities portfolio into the following security types: • Agency-sponsored obligations; • Mortgage-backed securities; • State and municipal obligations; and • Corporate obligations. All of the agency obligations held by the Company are issued by U.S. government entities and agencies. These securities are either explicitly or implicitly guaranteed by the U.S. government, are highly rated by major rating agencies and have a long history of no credit losses. The majority of the state and municipal and corporate obligations carry credit ratings from the rating agencies as of March 31, 2024, that were no lower than an A rating and the Company had no securities rated BBB or worse by Moody’s Investors Service. Credit Quality Indicators. The following table provides the amortized cost of held to maturity debt securities by credit rating as of March 31, 2024 and December 31, 2023 (in thousands): March 31, 2024 Total Portfolio AAA AA A BBB Not Rated Total Treasury obligations $ 5,767 — — — — 5,767 Agency-sponsored obligations 11,058 — — — — 11,058 State and municipal obligations 45,728 252,805 30,211 — 2,548 331,292 Corporate obligations 503 2,497 3,546 — 25 6,571 $ 63,056 255,302 33,757 — 2,573 354,688 December 31, 2023 Total Portfolio AAA AA A BBB Not Rated Total Treasury obligations $ 5,146 — — — — 5,146 Agency-sponsored obligations $ 11,058 — — — — 11,058 State and municipal obligations 43,749 156,438 137,231 — 2,398 339,816 Corporate obligations 504 2,510 4,052 — 25 7,091 $ 60,457 158,948 141,283 — 2,423 363,111 Credit quality indicators are metrics that provide information regarding the relative credit risk of debt securities.

The principal amounts of these non-accrual loans were $47.6 million and $49.6 million as of March 31, 2024 and December 31, 2023, respectively. Included in non-accrual loans were $4.6 million and $23.2 million of loans which were less than 90 days past due as of March 31, 2024 and December 31, 2023, respectively. There were no loans 90 days or greater past due and still accruing interest as of March 31, 2024 and December 31, 2023. The activity in the allowance for credit losses by portfolio segment for the three months ended March 31, 2024 and 2023 was as follows (in thousands): Three months ended March 31, Mortgage loans Commercial loans Consumer loans Total 2024 Balance at beginning of period $ 73,407 31,475 2,318 107,200 Provision charge (benefit) to operations (7,580) 7,924 (144) 200 Recoveries of loans previously charged-off 63 687 145 895 Loans charged-off — (1,794) (72) (1,866) Balance at end of period $ 65,890 38,292 2,247 106,429 2023 Balance at beginning of period $ 58,218 27,413 2,392 88,023 Cumulative effect of adopting ASU 2022-02 (510) (43) (41) (594) Provision charge to operations 6,212 (308) 96 6,000 Recoveries of loans previously charged-off 3 168 85 256 Loans charged-off (728) (113) (86) (927) Balance at end of period $ 63,195 27,117 2,446 92,758 For the three months ended March 31, 2024, the Company recorded a $200,000 provision for credit losses on loans, compared to a $6.0 million provision for the same period in 2023. The decrease in the provision for credit losses was largely a function of the period-over-period improvement in the economic forecast within our CECL model. For the three months ended March 31, 2024, net charge-offs totaled $971,000. The following table summarizes the Company's gross charge-offs recorded during the three months ended March 31, 2024 by year of origination (in thousands): 2024 2023 2022 2021 2020 Prior to 2020 Total Loans Commercial loans $ — — — — 1,606 188 1,794 Consumer loans (1) 6 — — — — 1 7 Total gross loans $ 6 — — — 1,606 189 1,801 (1) During the three months ended March 31, 2024, charge-offs on consumer overdraft accounts totaled $65,000, which are not included in the table above. The Company defines a loan individually evaluated for impairment as a non-homogeneous loan greater than $1.0 million, for which, based on current information, it is not expected to collect all amounts due under the contractual terms of the loan agreement. As of March 31, 2024, there were 14 loans totaling $40.1 million, compared to 17 loans totaling $42.3 million as of December 31, 2023, that were individually evaluated for impairment. A financial asset is considered collateral-dependent when the debtor is experiencing financial difficulty and repayment is expected to be provided substantially through the sale or operation of the collateral. For all classes of loans deemed collateral-dependent, the Company estimates expected credit losses based on the collateral’s fair value less any selling costs. A specific allocation of the allowance for credit losses is established for each collateral-dependent loan with a carrying balance greater than the collateral’s fair value, less estimated selling costs. In most cases, the Company records a partial charge-off to reduce the loan’s carrying value to the collateral’s fair value less estimated selling costs. The Company uses third-party appraisals to determine the fair value of the underlying collateral in its analysis of collateral-dependent loans. A third-party appraisal is generally ordered as soon as a loan is designated as a collateral-dependent loan and updated annually, or more frequently if required. At each fiscal quarter end, if a loan is designated as collateral-dependent and the third-party appraisal has not yet been received, an evaluation of all available collateral is made using the best information available at the time, including rent rolls, borrower financial statements and tax returns, prior appraisals, management’s knowledge of the market and collateral, and internally prepared collateral valuations based upon market assumptions regarding vacancy and capitalization rates, each as and where applicable. Once the appraisal is received and reviewed, the specific reserves are adjusted to reflect the appraised value and evaluated for charge offs. The Company believes there have been no significant time lapses resulting from this process. As of March 31, 2024 and December 31, 2023, the Company had collateral-dependent loans with fair values of $20.9 million and $24.1 million secured by commercial real estate, respectively. Loan modifications to borrowers experiencing financial difficulty may include interest rate reductions, principal or interest forgiveness, forbearance, term extensions, and other actions intended to minimize economic loss and to avoid foreclosure or repossession of collateral. In addition, management attempts to obtain additional collateral or guarantor support when modifying such loans. If the borrower has demonstrated performance under the previous terms and our underwriting process shows the borrower has the capacity to continue to perform under the restructured terms, the loan will continue to accrue interest. Non-accruing restructured loans may be returned to accrual status when there has been a sustained period of repayment performance (generally six consecutive months of payments) and both principal and interest are deemed collectible. The following illustrates the most common loan modifications by loan classes offered by the Company that are required to be disclosed pursuant to the requirements of ASU 2022-02: Loan Classes Modification types Commercial Term extension, interest rate reductions, payment delay, or combination thereof. These modifications extend the term of the loan, lower the payment amount, or otherwise delay payments during a defined period for the purpose of providing borrowers additional time to return to compliance with the original loan term. Residential Mortgage/ Home Equity Forbearance period greater than six months. These modifications require reduced or no payments during the forbearance period for the purpose of providing borrowers additional time to return to compliance with the original loan term, as well as term extension and rate adjustment. These modifications extend the term of the loan and provides for an adjustment to the interest rate, which reduces the monthly payment requirement. Direct Installment Term extension greater than three months. These modifications extend the term of the loan, which reduces the monthly payment requirement. In 2023, the Company adopted ASU 2022-02, “Financial Instruments - Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures” (“ASU 2022-02”), which eliminated the accounting guidance for troubled debt restructurings while enhancing disclosure requirements for certain loan refinancing and restructurings by creditors when a borrower is experiencing financial difficulty. This guidance was applied on a modified retrospective basis. Upon adoption of this guidance, 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 projected loss rate is applied to the current loan balance to arrive at the quantitative and qualitative baseline portion of the allowance for credit losses. As a result, the Company recorded a $594,000 reduction to the allowance for credit losses, which resulted in a $433,000 cumulative effect adjustment increase, net of tax, to retained earnings. The following table presents the amortized cost basis of loan modifications made to borrowers experiencing financial difficulty during the three months ended March 31, 2024 (in thousands): For the three months ended March 31, 2024 Term Extension Interest Rate Increase Interest Rate Reduction and Term Extension % of Total Class of Loans and Leases Commercial loans $ — 7,187 — 0.29 % Total gross loans $ — 7,187 — 0.07 % The following table presents the financial effect of loan modifications made to borrowers experiencing financial difficulty during the three months ended March 31, 2024 (in thousands): Weighted-Average Months of Term Extension Weighted-Average Rate Increase Commercial loans 0 2.00 % Total gross loans 0 2.00 % There were no loan modifications made to borrowers experiencing financial difficulty during the three months ended March 31, 2024, that subsequently defaulted. The following table presents the aging analysis of loan modifications made to borrowers experiencing financial difficulty during the three months ended March 31, 2024 (in thousands): Current 30-59 Days Past Due 60-89 Days Past Due 90 days or more Past Due Non- Accrual Total Commercial loans $ 7,187 — — — — 7,187 Total gross loans $ 7,187 — — — — 7,187 As allowed by CECL, loans acquired by the Company that experience more-than-insignificant deterioration in credit quality after origination, are classified as Purchased Credit Deteriorated ("PCD") loans. As of March 31, 2024, the balance of PCD loans totaled $160.6 million with a related allowance for credit losses of $1.6 million. The balance of PCD loans as of December 31, 2023 was $165.1 million with a related allowance for credit losses of $1.7 million. Management utilizes an internal nine-point risk rating system to summarize its loan portfolio into categories with similar risk characteristics. Loans deemed to be “acceptable quality” are rated 1 through 4, with a rating of 1 established for loans with minimal risk. Loans that are deemed to be of “questionable quality” are rated 5 (watch) or 6 (special mention). Loans with adverse classifications (substandard, doubtful or loss) are rated 7, 8 or 9, respectively. Commercial mortgage, commercial, multi-family and construction loans are rated individually, and each lending officer is responsible for risk rating loans in their portfolio. These risk ratings are then reviewed by the department manager and/or the Chief Lending Officer and by the Credit Department. The risk ratings are also reviewed periodically through loan review examinations which are currently performed by an independent third-party.

Retirement Benefits [Abstract]
Components of Net Periodic Benefit Cost	Components of Net Periodic Benefit Cost The Bank has a noncontributory defined benefit pension plan covering its full-time employees who had attained age 21 with at least one year of service as of April 1, 2003. The pension plan was frozen on April 1, 2003. All participants in the Plan are 100% vested. The pension plan’s assets are invested in investment funds and group annuity contracts currently managed by the Principal Financial Group and Allmerica Financial. In addition to pension benefits, certain health care and life insurance benefits are currently made available to certain of the Bank’s retired employees. The costs of such benefits are accrued based on actuarial assumptions from the date of hire to the date the employee is fully eligible to receive the benefits. Effective January 1, 2003, eligibility for retiree health care benefits was frozen as to new entrants, and benefits were eliminated for employees with less than ten years of service as of December 31, 2002. Effective January 1, 2007, eligibility for retiree life insurance benefits was frozen as to new entrants and retiree life insurance benefits were eliminated for employees with less than ten years of service as of December 31, 2006. Net periodic (benefit) increase cost for pension benefits and other post-retirement benefits for the three and three months ended March 31, 2024 and 2023, includes the following components (in thousands): Three months ended March 31, Pension benefits Other post-retirement benefits 2024 2023 2024 2023 Service cost $ — — 3 3 Interest cost 289 302 135 150 Expected return on plan assets (778) (706) — — Amortization of prior service cost — — — — Amortization of the net loss (gain) 14 177 (530) (533) Net periodic (decrease) increase in benefit cost $ (475) (227) (392) (380) In its consolidated financial statements for the year ended December 31, 2023, the Company previously disclosed that it does not expect to contribute to the pension plan in 2024. As of March 31, 2024, no contributions have been made to the pension plan. The changes in net periodic benefit cost for pension benefits and other post-retirement benefits for the three months ended March 31, 2024 were calculated using the January 1, 2023 pension and other post-retirement benefits actuarial valuations.

Accounting Changes and Error Corrections [Abstract]
Impact of Recent Accounting Pronouncements	Impact of Recent Accounting Pronouncements Accounting Pronouncements Adopted This Year In June 2022, FASB issued ASU 2022-03, “Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions”. The amendments in this ASU clarify that a contractual restriction on the sale of an equity security is not considered part of the unit of account of the equity security and, therefore, is not considered in measuring fair value. The amendments also clarify that an entity cannot, as a separate unit of account, recognize and measure a contractual sale restriction. In addition, this update introduces new disclosure requirements to provide information about the contractual sales restriction including the nature and remaining duration of the restriction. This update will be effective for financial statements issued for fiscal years and interim periods beginning after December 15, 2023, with early adoption in the interim period permitted. The Company adopted this standard on January 1, 2023 on a prospective basis; with no impact to the consolidated financial statements. Accounting Pronouncements Not Yet Adopted In December 2023, FASB issued ASU 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures”. The amendments in this ASU require improved annual income tax disclosures surrounding rate reconciliation, income taxes paid, and other disclosures. This update will be effective for financial statements issued for fiscal years beginning after December 15, 2024, with early adoption in the interim period permitted. The Company is currently evaluating the impact of this standard on the consolidated financial statements.

Commitments and Contingencies Disclosure [Abstract]
Contingencies	Contingencies The Company is involved in various litigation and claims arising in the normal course of business. Liabilities for loss contingencies arising from such litigation and claims are recorded when it is probable that a liability has been incurred and the amount can be reasonably estimated. On May 2, 2022, a purported class action complaint was filed against the Bank in the Superior Court of New Jersey, which alleges that the Bank wrongfully assessed overdraft fees related to debit card transactions. The complaint asserts claims for breach of contract and breach of the covenant of good faith and fair dealing as well as an alleged violation of the New Jersey Consumer Fraud Act. Plaintiff seeks to represent a proposed class of all the Bank's checking account customers who were charged overdraft fees on transactions that were authorized into a positive available balance. Plaintiff seeks unspecified damages, costs, attorneys’ fees, pre-judgment interest, an injunction, and other relief as the Court deems proper for the plaintiff and the proposed class. The Bank denies the allegations and is vigorously defending the matter. The parties had an initial mediation meeting on October 20, 2023, and the matter remains pending. Although the Bank is vigorously defending the litigation, the ultimate outcome of this litigation, such as whether the likelihood of loss is remote, reasonably possible, or probable, or if and when the reasonably possible range of loss is estimable, is inherently uncertain. As a result of this analysis, a $3.0 million charge was recorded in the fourth quarter of 2023 for estimated contingent litigation reserves.

Allowance for Credit Losses on

Credit Loss [Abstract]
Allowance for Credit Losses on Off-Balance Sheet Credit Exposures	Allowance for Credit Losses on Off-Balance Sheet Credit Exposures Management analyzes the Company's exposure to credit losses for both on-balance sheet and off-balance sheet activity using a consistent methodology for the quantitative framework as well as the qualitative framework. For purposes of estimating the allowance for credit losses for off-balance sheet credit exposures, the exposure that may default includes an estimated drawdown of unused credit based on historical credit utilization factors and current loss factors. For the three months ended March 31, 2024, the Company recorded a $506,000 provision benefit for credit losses on off-balance sheet credit exposures. For the three months ended March 31, 2023, the Company recorded a $739,000 provision charge for credit losses for off-balance sheet credit exposures. The $1.2 million decrease in the provision for the three months ended March 31, 2024, compared to the same period in 2023, was primarily due to a decrease in loans approved and awaiting closing. The allowance for credit losses for off-balance sheet credit exposures was $2.9 million as of March 31, 2024 and $3.4 million as of December 31, 2023, and is included in other liabilities on the Consolidated Statements of Financial Condition.

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements The Company utilizes fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures. The determination of fair values of financial instruments often requires the use of estimates. Where quoted market values in an active market are not readily available, management utilizes various valuation techniques to estimate fair value. Fair value is an estimate of the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. However, in many instances fair value estimates may not be substantiated by comparison to independent markets and may not be realized in an immediate sale of the financial instrument. GAAP establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy are as follows: Level 1: Unadjusted quoted market prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities; Level 2: Quoted prices in markets that are not active, or inputs that are observable either directly or indirectly, for substantially the full term of the asset or liability; and Level 3: Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (i.e., supported by little or no market activity). A financial instrument’s level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement. The valuation techniques are based upon the unpaid principal balance only, and exclude any accrued interest or dividends at the measurement date. Interest income and expense and dividend income are recorded within the consolidated statements of income depending on the nature of the instrument using the effective interest method based on acquired discount or premium. Assets and Liabilities Measured at Fair Value on a Recurring Basis The valuation techniques described below were used to measure fair value of financial instruments in the table below on a recurring basis as of March 31, 2024 and December 31, 2023. Available for Sale Debt Securities, at Fair Value For available for sale debt securities, fair value was estimated using a market approach. The majority of the Company’s securities are fixed income instruments that are not quoted on an exchange, but are traded in active markets. Prices for these instruments are obtained through third-party data service providers or dealer market participants with whom the Company has historically transacted both purchases and sales of securities. Prices obtained from these sources include market quotations and matrix pricing. Matrix pricing, a Level 2 input, is a mathematical technique used principally to value certain securities to benchmark to comparable securities. The Company evaluates the quality of Level 2 matrix pricing through comparison to similar assets with greater liquidity and evaluation of projected cash flows. As management is responsible for the determination of fair value, it performs quarterly analyses on the prices received from the pricing service to determine whether the prices are reasonable estimates of fair value. Specifically, management compares the prices received from the pricing service to a secondary pricing source. Additionally, management compares changes in the reported market values and returns to relevant market indices to test the reasonableness of the reported prices. The Company’s internal price verification procedures and review of fair value methodology documentation provided by independent pricing services has generally not resulted in an adjustment in the prices obtained from the pricing service. The Company also holds debt instruments issued by the U.S. government that are traded in active markets with readily accessible quoted market prices that are considered Level 1 within the fair value hierarchy. Equity Securities at Fair Value The Company holds equity securities that are traded in active markets with readily accessible quoted market prices that are considered Level 1 inputs. Derivatives The Company records all derivatives on the statements of financial condition at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, whether the Company has elected to designate a derivative in a hedging relationship and apply hedge accounting and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. The Company has interest rate derivatives resulting from a service provided to certain qualified borrowers in a loan related transaction which, therefore, are not used to manage interest rate risk in the Company’s assets or liabilities. As such, all changes in fair value of these derivatives are recognized directly in earnings. The Company also uses interest rate swaps as part of its interest rate risk management strategy. Interest rate swaps designated as cash flow hedges, and which satisfy hedge accounting requirements, involve the receipt of variable amounts from a counterparty in exchange for the Company making fixed-rate payments over the life of the agreements without the exchange of the underlying notional amount. These derivatives were used to hedge the variable cash outflows associated with FHLBNY borrowings and brokered demand deposits. The change in the fair value of these derivatives is recorded in accumulated other comprehensive income (loss), and is subsequently reclassified into earnings in the period that the forecasted transactions affect 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. Assets Measured at Fair Value on a Non-Recurring Basis The valuation techniques described below were used to estimate fair value of financial instruments measured on a non-recurring basis as of March 31, 2024 and December 31, 2023. Collateral-Dependent Impaired Loans For loans measured for impairment based on the fair value of the underlying collateral, fair value was estimated using a market approach. The Company measures the fair value of collateral underlying impaired loans primarily through obtaining independent appraisals that rely upon quoted market prices for similar assets in active markets. These appraisals include adjustments, on an individual case-by-case basis, to comparable assets based on the appraisers’ market knowledge and experience, as well as adjustments for estimated costs to sell between 5% and 10%. Management classifies these loans as Level 3 within the fair value hierarchy. Foreclosed Assets Assets acquired through foreclosure or deed in lieu of foreclosure are carried at fair value, less estimated selling costs, which range between 5% and 10%. Fair value is generally based on independent appraisals that rely upon quoted market prices for similar assets in active markets. These appraisals include adjustments, on an individual case basis, to comparable assets based on the appraisers’ market knowledge and experience, and are classified as Level 3. 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. A reserve for foreclosed assets may be established to provide for possible write-downs and selling costs that occur subsequent to foreclosure. Foreclosed assets are carried net of the related reserve. Operating results from real estate owned, including rental income, operating expenses, and gains and losses realized from the sales of real estate owned, are recorded as incurred. There were no changes to the valuation techniques for fair value measurements as of March 31, 2024 or December 31, 2023. The following tables present the assets and liabilities reported on the consolidated statements of financial condition at their fair values as of March 31, 2024 and December 31, 2023, by level within the fair value hierarchy (in thousands): Fair Value Measurements at Reporting Date Using: March 31, 2024 Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Measured on a recurring basis: Available for sale debt securities: U.S. Treasury obligations $ 252,387 252,387 — — Agency-guaranteed obligations 23,518 — 23,518 — Mortgage-backed securities 1,259,881 — 1,259,881 — Asset-backed securities 30,517 — 30,517 — State and municipal obligations 55,765 — 55,765 — Corporate obligations 44,238 — 44,238 — Total available for sale debt securities 1,666,306 252,387 1,413,919 — Equity securities 1,341 1,341 — — Derivative assets 114,427 — 114,427 — $ 1,782,074 253,728 1,528,346 — Derivative liabilities $ 101,256 — 101,256 — Measured on a non-recurring basis: Loans measured for impairment based on the fair value of the underlying collateral $ 20,854 — — 20,854 Foreclosed assets 11,324 — — 11,324 $ 32,178 — — 32,178 Fair Value Measurements at Reporting Date Using: December 31, 2023 Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Measured on a recurring basis: Available for sale debt securities: U.S. Treasury obligations $ 253,878 253,878 — — Agency-guaranteed obligations 27,498 — 27,498 — Mortgage-backed securities 1,285,609 — 1,285,609 — Asset-backed securities 32,235 — 32,235 — State and municipal obligations 56,584 — 56,584 — Corporate obligations 34,308 — 34,308 — Total available for sale debt securities 1,690,112 253,878 1,436,234 — Equity Securities 1,270 1,270 — — Derivative assets 101,754 — 101,754 — $ 1,793,136 255,148 1,537,988 — Derivative liabilities $ 88,835 — 88,835 — Measured on a non-recurring basis: Loans measured for impairment based on the fair value of the underlying collateral $ 24,139 — — 24,139 Foreclosed assets 11,651 — — 11,651 $ 35,790 — — 35,790 There were no transfers into or out of Level 3 during the three months ended March 31, 2024. Other Fair Value Disclosures The Company is required to disclose estimated fair value of financial instruments, both assets and liabilities on- and off- the balance sheet, for which it is practicable to estimate fair value. The following is a description of valuation methodologies used for those assets and liabilities. Cash and Cash Equivalents For cash and due from banks, federal funds sold and short-term investments, the carrying amount approximates fair value. As of March 31, 2024 and December 31, 2023, $70,000 was included in cash and cash equivalents, representing cash collateral pledged to secure loan level swaps and risk participation agreements. Held to Maturity Debt Securities For held to maturity debt securities, fair value was estimated using a market approach. The majority of the Company’s securities are fixed income instruments that are not quoted on an exchange, but are traded in active markets. Prices for these instruments are obtained through third party data service providers or dealer market participants with whom the Company has historically transacted both purchases and sales of securities. Prices obtained from these sources include market quotations and matrix pricing. Matrix pricing, a Level 2 input, is a mathematical technique used principally to value certain securities to benchmark to comparable securities. Management evaluates the quality of Level 2 matrix pricing through comparison to similar assets with greater liquidity and evaluation of projected cash flows. As management is responsible for the determination of fair value, it performs quarterly analyses on the prices received from the pricing service to determine whether the prices are reasonable estimates of fair value. Specifically, management compares the prices received from the pricing service to a secondary pricing source. Additionally, management compares changes in the reported market values and returns to relevant market indices to test the reasonableness of the reported prices. The Company’s internal price verification procedures and review of fair value methodology documentation provided by independent pricing services has generally not resulted in adjustment in the prices obtained from the pricing service. The Company also holds debt instruments issued by the U.S. government and U.S. government-sponsored agencies that are traded in active markets with readily accessible quoted market prices that are considered Level 1 within the fair value hierarchy. Federal Home Loan Bank of New York ("FHLBNY") Stock The carrying value of FHLBNY stock is its cost. The fair value of FHLBNY stock is based on redemption at par value. The Company classifies the estimated fair value as Level 1 within the fair value hierarchy. Loans Fair values are estimated for portfolios of loans with similar financial characteristics. Loans are segregated by type such as commercial mortgage, residential mortgage, commercial, construction and consumer. Each loan category is further segmented into fixed and adjustable-rate interest terms and into performing and non-performing categories. The fair value of performing loans was estimated using a combination of techniques, including a discounted cash flow model that utilizes a discount rate that reflects the Company’s current pricing for loans with similar characteristics and remaining maturity, adjusted by an amount for estimated credit losses inherent in the portfolio at the balance sheet date (i.e. exit pricing). The rates take into account the expected yield curve, as well as an adjustment for prepayment risk, when applicable. The Company classifies the estimated fair value of its loan portfolio as Level 3. The fair value for significant non-performing loans was based on recent external appraisals of collateral securing such loans, adjusted for the timing of anticipated cash flows. The Company classifies the estimated fair value of its non-performing loan portfolio as Level 3. Deposits The fair value of deposits with no stated maturity, such as non-interest bearing demand deposits and savings deposits, was equal to the amount payable on demand and classified as Level 1. The estimated fair value of certificates of deposit was based on the discounted value of contractual cash flows. The discount rate was estimated using the Company’s current rates offered for deposits with similar remaining maturities. The Company classifies the estimated fair value of its certificates of deposit portfolio as Level 2. Borrowed Funds The fair value of borrowed funds was estimated by discounting future cash flows using rates available for debt with similar terms and maturities and is classified by the Company as Level 2 within the fair value hierarchy. Commitments to Extend Credit and Letters of Credit The fair value of commitments to extend credit and letters of credit was 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 Company classifies these commitments as Level 3 within 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 loss experience, 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. Significant assets and liabilities that are not considered financial assets or liabilities include goodwill and other intangibles, deferred tax assets and premises and equipment. 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. The following tables present the Company’s financial instruments at their carrying and fair values as of March 31, 2024 and December 31, 2023. Fair values are presented by level within the fair value hierarchy.

Derivatives and Hedging Activit

Derivatives and Hedging Activities	3 Months Ended

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative and Hedging Activities	Derivative and Hedging Activities The Company is exposed to certain risks arising from both its business operations and economic conditions. The Company principally manages its exposures to a wide variety of business and operational risks through the management of its core business activities. The Company manages economic risks, including interest rate, liquidity, and credit risk, primarily by managing the amount, sources, and duration of its assets and liabilities. Non-designated Hedges. Derivatives not designated in qualifying hedging relationships are not speculative and result from a service the Company provides to certain qualified commercial borrowers in loan related transactions which, therefore, are not used to manage interest rate risk in the Company’s assets or liabilities. The Company may execute interest rate swaps with qualified commercial banking customers to facilitate their respective risk management strategies. Those interest rate swaps are simultaneously hedged by offsetting interest rate swaps that the Company executes with a third party, such that the Company minimizes its net risk exposure resulting from such transactions. The interest rate swap agreement which the Company executes with the commercial borrower is collateralized by the borrower's commercial real estate financed by the Company. As the Company has not elected to apply hedge accounting and 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. As of March 31, 2024 and December 31, 2023, the Company had 152 and 154 loan related interest rate swaps with aggregate notional amounts of $2.23 billion and $2.30 billion, respectively. The Company periodically enters into risk participation agreements ("RPAs"), with the Company functioning as either the lead institution, or as a participant when another company is the lead institution on a commercial loan. These RPAs are entered into to manage the credit exposure on interest rate contracts associated with these loan participation agreements. Under the RPAs, the Company will either receive or make a payment in the event the borrower defaults on the related interest rate contract. The Company has minimum collateral posting thresholds with certain of its risk participation counterparties, and has posted collateral of $70,000 against the potential risk of default by the borrower under these agreements. For March 31, 2024 and December 31, 2023, the Company had 12 credit derivatives, respectively, with aggregate notional amounts of $188.4 million and $142.8 million, respectively, from participations in interest rate swaps as part of these loan participation arrangements. As of March 31, 2024, the asset and liability positions of these fair value credit derivatives totaled $9,000 and $5,000, respectively, compared to $17,000 and $8,000, respectively, as of December 31, 2023. Cash Flow Hedges of Interest Rate Risk. The Company’s objective in using interest rate derivatives is to add stability to interest expense and to manage exposure to interest rate movements. To accomplish this objective, the Company primarily uses interest rate swaps as part of its interest rate risk management strategy. Interest rate swaps designated as cash flow hedges involve the receipt of variable payment amounts from a counterparty in exchange for the Company making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount. Changes in the fair value of derivatives designated and that qualify as cash flow hedges of interest rate risk are recorded in accumulated other comprehensive (loss) income and are subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. During the three months ended March 31, 2024 and 2023, such derivatives were used to hedge the variable cash outflows associated with FHLBNY borrowings. Amounts reported in accumulated other comprehensive income related to derivatives will be reclassified to interest expense as interest payments are made on the Company’s borrowings or demand deposits. During the next twelve months, the Company estimates that $11.1 million will be reclassified as a reduction to interest expense. As of March 31, 2024, the Company had 7 outstanding interest rate derivatives with an aggregate notional amount of $375.0 million that were each designated as a cash flow hedge of interest rate risk, compared to 9 outstanding interest rate derivatives with an aggregate notional amount of $455.0 million, as of December 31, 2023. Assets and liabilities relating to certain financial instruments, including derivatives, may be eligible for offset in the Consolidated Statements of Financial Condition and/or subject to enforceable master netting arrangements or similar agreements.

Revenue from Contract with Customer [Abstract]
Revenue Recognition	Revenue Recognition The Company generates revenue from several business channels. The guidance in ASU 2014-09, Revenue from Contracts with Customers (Topic 606) does not apply to revenue associated with financial instruments, including interest income on loans and investments, which comprise the majority of the Company's revenue. For the three months ended March 31, 2024, the out-of-scope revenue related to financial instruments was 88.7% of the Company's total revenue, compared to 86.6% for the three months ended March 31, 2023, respectively. Revenue-generating activities that are within the scope of Topic 606, are components of non-interest income. These revenue streams are generally classified into three categories: wealth management revenue, insurance agency income and banking service charges and other fees. The following table presents non-interest income, segregated by revenue streams in-scope and out-of-scope of Topic 606, for the three months ended March 31, 2024 and 2023 (in thousands): Three months ended March 31, 2024 2023 Non-interest income In-scope of Topic 606: Wealth management fees $ 7,488 6,915 Insurance agency income 4,793 4,102 Banking service charges and other fees: Service charges on deposit accounts 3,316 3,362 Debit card and ATM fees 688 706 Total banking service charges and other fees 4,004 4,068 Total in-scope non-interest income 16,285 15,085 Total out-of-scope non-interest income 4,522 7,067 Total non-interest income $ 20,807 22,152 Wealth management fee income represents fees earned from customers as consideration for asset management, investment advisory and trust services. The Company’s performance obligation is generally satisfied monthly and the resulting fees are recognized monthly. The fee is generally based upon the average market value of the assets under management for the month and the applicable fee rate. The monthly accrual of wealth management fees is recorded in other assets on the Company's Consolidated Statements of Financial Condition. Fees are received from the customer on a monthly basis. The Company does not earn performance-based incentives. To a lesser extent, optional services such as tax return preparation and estate settlement are also available to existing customers. The Company’s performance obligation for these transaction-based services is generally satisfied, and related revenue recognized, at either a point in time when the service is completed, or in the case of estate settlement, over a relatively short period of time, as each service component is completed. Insurance agency income, consisting of commissions and fees, is generally recognized as of the effective date of the insurance policy. Commission revenues related to installment billings are recognized on the invoice date. Subsequent commission adjustments are recognized upon the receipt of notification from insurance companies concerning matters necessitating such adjustments. Profit-sharing contingent commissions are recognized when determinable, which is generally when such commissions are received from insurance companies, or when the Company receives formal notification of the amount of such payments. Service charges on deposit accounts include account analysis fees and other deposit-related fees. These fees are generally transaction-based, or time-based services. The Company's performance obligation for these services is generally satisfied, and revenue recognized, at the time the transaction is completed, or the service rendered. Fees for these services are generally received from the customer either at the time of transaction, or monthly. Debit card and ATM fees are generally transaction-based. Debit card revenue is primarily comprised of interchange fees earned when a customer's Company card is processed through a card payment network. ATM fees are largely generated when a Company cardholder uses a non-Company ATM, or a non-Company cardholder uses a Company ATM. The Company's performance obligation for these services is satisfied when the service is rendered. Payment is generally received at the time of transaction or monthly. Out-of-scope non-interest income primarily consists of Bank-owned life insurance and net fees on loan level interest rate swaps, along with gains and losses on the sale of loans and foreclosed real estate, loan prepayment fees and loan servicing fees. None of these revenue streams are subject to the requirements of Topic 606.

Leases [Abstract]
Leases	Leases The following table represents the consolidated statements of financial condition classification of the Company’s right-of use-assets and lease liabilities as of March 31, 2024 and December 31, 2023 (in thousands): Classification March 31, 2024 December 31, 2023 Lease Right-of-Use Assets: Operating lease right-of-use assets Other assets $ 55,506 56,907 Lease Liabilities: Operating lease liabilities Other liabilities $ 58,611 60,039 The calculated amount of the right-of-use assets and lease liabilities in the table above are impacted by the length of the lease term and the discount rate used to present value the minimum lease payments. The Company’s lease agreements often include one or more options to renew at the Company’s discretion. If at lease inception the Company considers the exercising of a renewal option to be reasonably certain, the Company will include the extended term in the calculation of the right-of-use asset and lease liability. Regarding the discount rate, Topic 842 requires the use of the rate implicit in the lease whenever this rate is readily determinable. As this rate is rarely determinable, the Company utilizes its incremental borrowing rate at lease inception based upon the term of the lease. For operating leases existing prior to January 1, 2019, the rate for the remaining lease term as of January 1, 2019 was applied. All of the leases in which the Company is the lessee are classified as operating leases and are primarily comprised of real estate properties for branches and administrative offices with terms extending through 2040. As of March 31, 2024, the weighted-average remaining lease term and the weighted-average discount rate for the Company's operating leases were 7.7 years and 2.71%, respectively. The following tables represent lease costs and other lease information for the Company's operating leases. The variable lease cost primarily represents variable payments such as common area maintenance and utilities (in thousands): Three months ended March 31, 2024 Three months ended March 31, 2023 Lease Costs Operating lease cost $ 2,627 2,628 Variable lease cost 785 880 Total lease cost $ 3,412 3,508 Cash paid for amounts included in the measurement of lease liabilities: Three months ended March 31, 2024 Three months ended March 31, 2023 Operating cash flows from operating leases $ 2,557 2,349 Future minimum payments for operating leases with initial or remaining terms of one year or more as of March 31, 2024, were as follows (in thousands): Operating leases Twelve months ended: Remainder of 2024 $ 7,605 2025 9,701 2026 8,813 2027 7,985 2028 7,103 Thereafter 23,843 Total future minimum lease payments 65,050 Amounts representing interest 6,439 Present value of net future minimum lease payments $ 58,611

Accounting Policies [Abstract]
Basis of Financial Statement Presentation	Basis of Financial Statement Presentation The accompanying unaudited consolidated financial statements include the accounts of Provident Financial Services, Inc. (the "Company") and its wholly owned subsidiary, Provident Bank (the “Bank") and its wholly owned subsidiaries. In preparing the interim unaudited 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 consolidated statements of financial condition and the consolidated statements of income for the periods presented. Actual results could differ from these estimates. The allowance for credit losses is a material estimate that is particularly susceptible to near-term change. The interim unaudited consolidated financial statements reflect all normal and recurring adjustments, which are, in the opinion of management, considered necessary for a fair presentation of the financial condition and results of operations for the periods presented. The results of operations for the three months ended March 31, 2024 are not necessarily indicative of the results of operations that may be expected for all of 2024.
Loans Receivable and Allowance for Credit Losses	Loans Receivable and Allowance for Credit Losses The impact of utilizing the current expected credit loss ("CECL") methodology approach to calculate the allowance for credit losses on loans is significantly influenced by the composition, characteristics and quality of the Company’s loan portfolio, as well as the prevailing economic conditions and forecast utilized. Material changes to these and other relevant factors may result in greater volatility to the allowance for credit losses, and therefore, greater volatility to the Company’s reported earnings. For the three months ended March 31, 2024, an increase in specific reserves on impaired credits, partially offset by an improved economic forecast for the current quarter within our CECL model, led to a provisions charge for credit losses, while a decrease in loans approved and awaiting closing led to a provision benefit for credit losses on off-balance sheet credit exposures. See Notes 4 and 10 to the Consolidated Financial Statements for more information on the allowance for credit losses on loans and off-balance sheet credit exposures.
Goodwill	GoodwillGoodwill represents the excess of the purchase price over the estimated fair value of identifiable net assets acquired through purchase acquisitions. In accordance with GAAP, goodwill with an indefinite useful life is not amortized, but is evaluated for impairment on an annual basis, or more frequently if events or changes in circumstances indicate potential impairment between annual measurement dates. Goodwill is analyzed for impairment at least once a year. As permitted by GAAP, the Company prepares a qualitative assessment in determining whether goodwill may be impaired. The factors considered in the assessment include macroeconomic conditions, industry and market conditions and overall financial performance of the Company, among others. The Company completed its most recent annual goodwill impairment test as of July 1, 2023. As of March 31, 2024, the Company performed a qualitative analysis of goodwill and concluded that no triggering events were identified and therefore a test for impairment between annual tests was not required.
Accounting Pronoucements Adopted This Year and Not Yet Adopted
Fair Value Measurements	The Company utilizes fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures. The determination of fair values of financial instruments often requires the use of estimates. Where quoted market values in an active market are not readily available, management utilizes various valuation techniques to estimate fair value. Fair value is an estimate of the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. However, in many instances fair value estimates may not be substantiated by comparison to independent markets and may not be realized in an immediate sale of the financial instrument. GAAP establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy are as follows: Level 1: Unadjusted quoted market prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities; Level 2: Quoted prices in markets that are not active, or inputs that are observable either directly or indirectly, for substantially the full term of the asset or liability; and Level 3: Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (i.e., supported by little or no market activity). A financial instrument’s level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement. The valuation techniques are based upon the unpaid principal balance only, and exclude any accrued interest or dividends at the measurement date. Interest income and expense and dividend income are recorded within the consolidated statements of income depending on the nature of the instrument using the effective interest method based on acquired discount or premium. Assets and Liabilities Measured at Fair Value on a Recurring Basis The valuation techniques described below were used to measure fair value of financial instruments in the table below on a recurring basis as of March 31, 2024 and December 31, 2023. Available for Sale Debt Securities, at Fair Value For available for sale debt securities, fair value was estimated using a market approach. The majority of the Company’s securities are fixed income instruments that are not quoted on an exchange, but are traded in active markets. Prices for these instruments are obtained through third-party data service providers or dealer market participants with whom the Company has historically transacted both purchases and sales of securities. Prices obtained from these sources include market quotations and matrix pricing. Matrix pricing, a Level 2 input, is a mathematical technique used principally to value certain securities to benchmark to comparable securities. The Company evaluates the quality of Level 2 matrix pricing through comparison to similar assets with greater liquidity and evaluation of projected cash flows. As management is responsible for the determination of fair value, it performs quarterly analyses on the prices received from the pricing service to determine whether the prices are reasonable estimates of fair value. Specifically, management compares the prices received from the pricing service to a secondary pricing source. Additionally, management compares changes in the reported market values and returns to relevant market indices to test the reasonableness of the reported prices. The Company’s internal price verification procedures and review of fair value methodology documentation provided by independent pricing services has generally not resulted in an adjustment in the prices obtained from the pricing service. The Company also holds debt instruments issued by the U.S. government that are traded in active markets with readily accessible quoted market prices that are considered Level 1 within the fair value hierarchy. Equity Securities at Fair Value The Company holds equity securities that are traded in active markets with readily accessible quoted market prices that are considered Level 1 inputs. Derivatives The Company records all derivatives on the statements of financial condition at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, whether the Company has elected to designate a derivative in a hedging relationship and apply hedge accounting and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. The Company has interest rate derivatives resulting from a service provided to certain qualified borrowers in a loan related transaction which, therefore, are not used to manage interest rate risk in the Company’s assets or liabilities. As such, all changes in fair value of these derivatives are recognized directly in earnings. The Company also uses interest rate swaps as part of its interest rate risk management strategy. Interest rate swaps designated as cash flow hedges, and which satisfy hedge accounting requirements, involve the receipt of variable amounts from a counterparty in exchange for the Company making fixed-rate payments over the life of the agreements without the exchange of the underlying notional amount. These derivatives were used to hedge the variable cash outflows associated with FHLBNY borrowings and brokered demand deposits. The change in the fair value of these derivatives is recorded in accumulated other comprehensive income (loss), and is subsequently reclassified into earnings in the period that the forecasted transactions affect 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. Assets Measured at Fair Value on a Non-Recurring Basis The valuation techniques described below were used to estimate fair value of financial instruments measured on a non-recurring basis as of March 31, 2024 and December 31, 2023. Collateral-Dependent Impaired Loans For loans measured for impairment based on the fair value of the underlying collateral, fair value was estimated using a market approach. The Company measures the fair value of collateral underlying impaired loans primarily through obtaining independent appraisals that rely upon quoted market prices for similar assets in active markets. These appraisals include adjustments, on an individual case-by-case basis, to comparable assets based on the appraisers’ market knowledge and experience, as well as adjustments for estimated costs to sell between 5% and 10%. Management classifies these loans as Level 3 within the fair value hierarchy.
Revenue Recognition	Wealth management fee income represents fees earned from customers as consideration for asset management, investment advisory and trust services. The Company’s performance obligation is generally satisfied monthly and the resulting fees are recognized monthly. The fee is generally based upon the average market value of the assets under management for the month and the applicable fee rate. The monthly accrual of wealth management fees is recorded in other assets on the Company's Consolidated Statements of Financial Condition. Fees are received from the customer on a monthly basis. The Company does not earn performance-based incentives. To a lesser extent, optional services such as tax return preparation and estate settlement are also available to existing customers. The Company’s performance obligation for these transaction-based services is generally satisfied, and related revenue recognized, at either a point in time when the service is completed, or in the case of estate settlement, over a relatively short period of time, as each service component is completed. Insurance agency income, consisting of commissions and fees, is generally recognized as of the effective date of the insurance policy. Commission revenues related to installment billings are recognized on the invoice date. Subsequent commission adjustments are recognized upon the receipt of notification from insurance companies concerning matters necessitating such adjustments. Profit-sharing contingent commissions are recognized when determinable, which is generally when such commissions are received from insurance companies, or when the Company receives formal notification of the amount of such payments. Service charges on deposit accounts include account analysis fees and other deposit-related fees. These fees are generally transaction-based, or time-based services. The Company's performance obligation for these services is generally satisfied, and revenue recognized, at the time the transaction is completed, or the service rendered. Fees for these services are generally received from the customer either at the time of transaction, or monthly. Debit card and ATM fees are generally transaction-based. Debit card revenue is primarily comprised of interchange fees earned when a customer's Company card is processed through a card payment network. ATM fees are largely generated when a Company cardholder uses a non-Company ATM, or a non-Company cardholder uses a Company ATM. The Company's performance obligation for these services is satisfied when the service is rendered. Payment is generally received at the time of transaction or monthly. Out-of-scope non-interest income primarily consists of Bank-owned life insurance and net fees on loan level interest rate swaps, along with gains and losses on the sale of loans and foreclosed real estate, loan prepayment fees and loan servicing fees. None of these revenue streams are subject to the requirements of Topic 606.
