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 and nine months ended September 30, 2023 are not necessarily indicative of the results of operations that may be expected for all of 2023. 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, 2022 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 and nine months ended September 30, 2023 and 2022 (dollars in thousands, except per share amounts): Three months ended September 30, 2023 2022 Net Weighted Per Net Weighted Per Net income $ 28,547 $ 43,421 Basic earnings per share: Income available to common stockholders $ 28,547 74,909,083 $ 0.38 $ 43,421 74,297,237 $ 0.58 Dilutive shares 5,122 96,143 Diluted earnings per share: Income available to common stockholders $ 28,547 74,914,205 $ 0.38 $ 43,421 74,393,380 $ 0.58 Nine months ended September 30, 2023 2022 Net Weighted Per Net Weighted Per Net income $ 101,086 $ 126,613 Basic earnings per share: Income available to common stockholders $ 101,086 74,793,530 $ 1.35 $ 126,613 74,808,358 $ 1.69 Dilutive shares 23,076 88,135 Diluted earnings per share: Income available to common stockholders $ 101,086 74,816,606 $ 1.35 $ 126,613 74,896,493 $ 1.69 Anti-dilutive stock options and awards at September 30, 2023 and 2022, totaling 1.2 million shares and 921,834 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 and nine months ended September 30, 2023, a worsened economic forecast and related deterioration in the projected commercial property price indices over the expected life of the loan portfolio within our CECL model led to increases to the provisions for credit losses and 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

Investments, Debt and Equity Securities [Abstract]
Investment Securities	Investment Securities At September 30, 2023, the Company had $1.66 billion and $370.4 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 at September 30, 2023 totaled 1,065, compared with 914 at December 31, 2022. The increase in the number of securities in an unrealized loss position at September 30, 2023 was due to higher current market interest rates compared to rates at December 31, 2022. Available for Sale Debt Securities The following tables present the amortized cost, gross unrealized gains, gross unrealized losses and the fair value for available for sale debt securities at September 30, 2023 and December 31, 2022 (in thousands): September 30, 2023 Amortized Gross Gross Fair U.S. Treasury obligations $ 276,364 — (31,037) 245,327 Agency obligations 28,208 62 (22) 28,248 Mortgage-backed securities 1,503,545 8 (240,409) 1,263,144 Asset-backed securities 33,100 625 (211) 33,514 State and municipal obligations 64,697 — (12,657) 52,040 Corporate obligations 40,472 — (6,440) 34,032 $ 1,946,386 695 (290,776) 1,656,305 December 31, 2022 Amortized Gross Gross Fair U.S. Treasury obligations $ 275,620 — (29,804) 245,816 Mortgage-backed securities 1,636,913 209 (209,983) 1,427,139 Asset-backed securities 37,706 278 (363) 37,621 State and municipal obligations 67,706 — (10,842) 56,864 Corporate obligations 40,540 50 (4,482) 36,108 $ 2,058,485 537 (255,474) 1,803,548 The amortized cost and fair value of available for sale debt securities at September 30, 2023, 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.

There were no sales of securities from the available for sale debt securities portfolio for the three and nine months ended September 30, 2023 and 2022. For the three and nine months ended September 30, 2023, there were no proceeds from calls on securities in the available for sale debt securities portfolio. For the three and nine months ended September 30, 2022, proceeds from calls on securities in the available for sale debt securities portfolio totaled $5.4 million with gains of $84,000 and $26,000 of losses recognized, respectively. The number of available for sale debt securities in an unrealized loss position at September 30, 2023 totaled 474, compared with 475 at December 31, 2022. The decline in the number of securities in an unrealized loss position at September 30, 2023 was due to maturities and calls of securities in the quarter. All securities in an unrealized loss position were investment grade at September 30, 2023. Held to Maturity Debt Securities The following tables present the amortized cost, gross unrealized gains, gross unrealized losses and the estimated fair value for held to maturity debt securities at September 30, 2023 and December 31, 2022 (in thousands): September 30, 2023 Amortized Gross Gross Fair Treasury Obligations $ 1,135 — — 1,135 Agency obligations 12,098 — (897) 11,201 State and municipal obligations 348,493 2 (25,905) 322,590 Corporate obligations 8,724 — (568) 8,156 $ 370,450 2 (27,370) 343,082 December 31, 2022 Amortized Gross Gross Fair Agency obligations $ 9,997 — (1,033) 8,964 State and municipal obligations 366,164 268 (13,015) 353,417 Corporate obligations 11,789 1 (703) 11,087 $ 387,950 269 (14,751) 373,468 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 and nine months ended September 30, 2023 and 2022. For the three and nine months ended September 30, 2023, proceeds from calls on securities in the held to maturity debt securities portfolio totaled $3.2 million and $9.8 million, respectively. As to these calls on securities, for the three months ended September 30, 2023, there were gross gains of $16,000 and gross losses of $3,000, while for the nine months ended September 30, 2023, gross gains totaled $45,000, with gross losses of $8,000. For the three and nine months ended September 30, 2022, proceeds from calls on securities in the held to maturity debt securities portfolio totaled $10.3 million and $36.4 million, respectively. As to these calls on securities, for the three months ended September 30, 2022, gross gains totaled $26,000, with gross losses of $29,000, while for the nine months ended September 30, 2022, gross gains totaled $129,000, with $33,000 of gross losses. The amortized cost and fair value of investment securities in the held to maturity debt securities portfolio at September 30, 2023 by contractual maturity are shown below (in thousands).

The number of held to maturity debt securities in an unrealized loss position at September 30, 2023 totaled 591, compared with 439 at December 31, 2022. The increase in the number of securities in an unrealized loss position at September 30, 2023, was due to higher current market interest rates compared to rates at December 31, 2022. 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 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 at September 30, 2023 no lower than A 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 at September 30, 2023 and December 31, 2022 (in thousands): September 30, 2023 Total Portfolio AAA AA A BBB Not Rated Total Treasury obligations $ 1,135 — — — — 1,135 Agency obligations 12,098 — — — — 12,098 State and municipal obligations 44,978 162,676 139,146 — 1,693 348,493 Corporate obligations 505 2,062 6,132 — 25 8,724 $ 58,716 164,738 145,278 — 1,718 370,450 December 31, 2022 Total Portfolio AAA AA A BBB Not Rated Total Agency obligations $ 9,997 — — — — 9,997 State and municipal obligations 48,453 171,934 143,829 770 1,178 366,164 Corporate obligations 507 3,592 7,415 — 275 11,789 $ 58,957 175,526 151,244 770 1,453 387,950 Credit quality indicators are metrics that provide information regarding the relative credit risk of debt securities.

The increase in provision was attributable to a worsened economic forecast and related deterioration in the projected commercial property price indices used in our CECL model. For the three months ended September 30, 2023, net charge-offs totaled $5.5 million, which was primarily attributable to one commercial loan. For the nine months ended September 30, 2023, net charge-offs totaled $7.3 million, which was primarily attributable to two commercial loans. The following table summarizes the Company's gross charge-offs recorded during the three months ended September 30, 2023 by year of origination (in thousands): 2023 2022 2021 2020 2019 Prior to 2019 Total Loans Mortgage loans: Residential $ — — — — — 3 3 Total mortgage loans — — — — — 3 3 Commercial loans $ — — — 5,000 — 1,019 6,019 Consumer loans (1) 7 — — — — — 7 Total gross loans $ 7 — — 5,000 — 1,022 6,029 (1) During the three months ended September 30, 2023, charge-offs on consumer overdraft accounts totaled $75,000, which are not included in the table above. The following table summarizes the Company's gross charge-offs recorded during the nine months ended September 30, 2023 by year of origination (in thousands): 2023 2022 2021 2020 2019 Prior to 2019 Total Loans Mortgage loans: Commercial $ — — — — — 707 707 Residential — — — — — 24 24 Total mortgage loans — — — — — 731 731 Commercial loans $ — — — 5,000 — 2,445 7,445 Consumer loans (1) 16 — — — — 13 29 Total gross loans $ 16 — — 5,000 — 3,189 8,205 (1) During the nine months ended September 30, 2023, charge-offs on consumer overdraft accounts totaled $221,000, 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. At September 30, 2023, there were 18 loans totaling $30.4 million, compared to 10 loans totaling $42.8 million at December 31, 2022, 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. At September 30, 2023, the Company had collateral-dependent loans with a fair value of $5.0 million secured by business assets and $2.0 million secured by commercial real estate. At December 31, 2022, the Company had collateral-dependent loans with a fair value of $21.3 million secured by commercial real estate, $1.9 million secured by business assets and $800,000 secured by residential real estate. 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. Automobile/ Direct Installment Term extension greater than three months. These modifications extend the term of the loan, which reduces the monthly payment requirement. Effective January 1, 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 (“TDRs”) 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 historical loss rate is applied to the current loan balance to arrive at the quantitative and qualitative baseline portion of the allowance for credit losses. 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.

However, our TDR accounting described herein was suspended for most of our loss mitigation activities through our election to account for certain eligible loss mitigation activities occurring between March 2020 and January 1, 2022 under the COVID-19 relief granted pursuant to the CARES Act and the Consolidated Appropriations Act of 2021. Effective January 1, 2023, we adopted ASU 2022-02, which eliminated TDR accounting prospectively for all restructurings occurring on or after January 1, 2023. The following tables present the number of loans modified as TDRs during the three and nine months ended September 30, 2022, along with their balances immediately prior to the modification date and post-modification as of September 30, 2022 (in thousands): For the three months ended September 30, 2022 Troubled Debt Restructurings Number of Pre-Modification Post-Modification Consumer loans 1 108 88 Total restructured loans 1 $ 108 88 For the nine months ended September 30, 2022 Troubled Debt Restructurings Number of Pre-Modification Post-Modification Mortgage loans: Residential 2 $ 265 $ 204 Multi-family 1 1,618 1,583 Total mortgage loans 3 1,883 1,787 Commercial loans 2 378 273 Consumer loans 1 108 88 Total restructured loans 6 $ 2,369 $ 2,148 Durin g the nine months ended September 30, 2022, $921,000 of charge-offs were recorded on collateral-dependent impaired loans. There was one loan totaling $209,000 which had a payment default (90 days or more past due) for a loan modified as a TDR within the 12 month period ending September 30, 2023. For TDRs that subsequently defaulted, the Company determined the amount of the allowance for the respective loans in accordance with the accounting policy for the allowance for credit losses on loans individually evaluated for impairment. 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. At September 30, 2023, the balance of PCD loans totaled $166.9 million with a related allowance for credit losses of $1.5 million. The balance of PCD loans at December 31, 2022 was $193.0 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. Reports by the independent third-party are presented to the Audit Committee of the Board of Directors. The Company participated in the Paycheck Protection Program (“PPP”) through the United States Department of the Treasury and Small Business Administration. PPP loans were fully guaranteed by the SBA and were eligible for forgiveness by the SBA to the extent that the proceeds were used to cover eligible payroll costs, interest costs, rent, and utility costs over a period of up to 24 weeks after the loan was made as long as certain conditions were met regarding employee retention and compensation levels. PPP loans deemed eligible for forgiveness by the SBA are to be repaid by the SBA to the Company. Eligibility ended for this program in May of 2021. PPP loans are included in our commercial loan portfolio. Under the PPP, the Company secured 2,067 PPP loans for its customers totaling $682.0 million. As of September 30, 2023, 2,054 PPP loans totaling $679.4 million were forgiven and repaid by the SBA. The balance of PPP loans at September 30, 2023 was $2.6 million.

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 nine months ended September 30, 2023 and 2022 includes the following components (in thousands): Three months ended September 30, Nine months ended September 30, Pension benefits Other post-retirement benefits Pension benefits Other post-retirement benefits 2023 2022 2023 2022 2023 2022 2023 2022 Service cost $ — — 3 7 $ — — 9 21 Interest cost 302 214 150 111 906 642 450 333 Expected return on plan assets (706) (864) — — (2,118) (2,592) — — Amortization of prior service cost — — — — — — — — Amortization of the net loss (gain) 177 — (532) (326) 531 — (1,598) (978) Net periodic (decrease) increase in benefit cost $ (227) (650) (379) (208) $ (681) (1,950) (1,139) (624) In its consolidated financial statements for the year ended December 31, 2022, the Company previously disclosed that it does not expect to contribute to the pension plan in 2023. As of September 30, 2023, 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 and nine months ended September 30, 2023 were calculated using the January 1, 2023 pension and other post-retirement benefits actuarial valuations.

Impact of Recent Accounting Pro

Accounting Changes and Error Corrections [Abstract]
Impact of Recent Accounting Pronouncements	Impact of Recent Accounting Pronouncements Accounting Pronouncements Adopted This Year In March 2022, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2022-02, "Financial Instruments-Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures," which addresses areas identified by the FASB as part of its post-implementation review of the credit losses standard (ASU 2016-13) that introduced the CECL model. The amendments eliminate the accounting guidance for troubled debt restructurings by creditors that have adopted the CECL model and enhance the disclosure requirements for loan refinancing and restructurings made with borrowers experiencing financial difficulty. In addition, the amendments require a public business entity to disclose current-period gross write-offs for financing receivables and net investment in leases by year of origination in the vintage disclosures. For entities that have adopted ASU 2016-13, ASU 2022-02 was effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. Early adoption was permitted if an entity had adopted ASU 2016-13. The Company adopted this ASU on January 1, 2023 using the modified retrospective method for all financial assets measured at amortized cost. Results for reporting periods beginning after January 1, 2023 are presented under ASC 326 while prior period amounts continue to be recorded with previously applicable GAAP. 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. In March 2022, the FASB issued Accounting Standards Update (ASU) 2022-01, Derivatives and Hedging (Topic 815): Fair Value Hedging – Portfolio Layer Method . The purpose of this updated guidance is to further align risk management objectives with hedge accounting results on the application of the last-of-layer method, which was first introduced in ASU 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities. ASU 2022-01 is effective for public business entities for fiscal years beginning after December 15, 2022, 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. In March 2020, the FASB issued ASU 2020-04, "Reference Rate Reform (Topic 848)," which provides optional expedients and exceptions for applying GAAP to loan and lease agreements, derivative contracts, and other transactions affected by the anticipated transition away from LIBOR toward new interest rate benchmarks. For transactions that are modified because of reference rate reform and that meet certain scope guidance: (i) modifications of loan agreements should be accounted for by prospectively adjusting the effective interest rate and the modification will be considered "minor" so that any existing unamortized origination fees/costs would carry forward and continue to be amortized; and (ii) modifications of lease agreements should be accounted for as a continuation of the existing agreement with no reassessments of the lease classification and the discount rate or re-measurements of lease payments that otherwise would be required for modifications not accounted for as separate contracts. ASU 2020-04 also provides numerous optional expedients for derivative accounting. In addition, in January 2021, the FASB issued ASU No. 2021-01 “Reference Rate Reform — Scope,” which clarified the scope of ASC 848 relating to contract modifications. The Company has reviewed all of its LIBOR-based products and all products have been adjusted to another index or are scheduled to be adjusted at their next repricing, as LIBOR ceased to be published after June 30,

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 Provident Bank in the Superior Court of New Jersey, which alleges that Provident 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 Provident Bank 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. Provident 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 we are vigorously defending the litigation, the ultimate outcome of this litigation described in this section, 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. Therefore, if this matter was resolved against us, our results of operations and financial condition, including in a particular reporting period in which any such outcome becomes probable and estimable, could be adversely affected.

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 and nine months ended September 30, 2023, the Company recorded a $1.5 million and a $1.6 million provision for credit losses for off-balance sheet credit exposures, respectively. For the three and nine months ended September 30, 2022, the Company recorded a $1.6 million provision for credit losses for off-balance sheet credit exposures and a $1.8 million provision benefit for credit losses for off-balance sheet credit exposures, respectively. The $43,000 decrease in the provision for the three months ended September 30, 2023, compared to the same period in 2022, was primarily the result of the period-over-period relative change in line of credit utilization. The $3.4 million increase in the provision for the nine months ended September 30, 2023, compared to the nine months ended September 30, 2022, was primarily the result of the period-over-period relative change in line of credit utilization and an increase in loans approved and awaiting closing. The allowance for credit losses for off-balance sheet credit exposures was $4.8 million at September 30, 2023 and $3.2 million at December 31, 2022, and are included in other liabilities on the Consolidated Statements of Financial Condition.

Fair Value Measurements

Fair Value Measurements	9 Months Ended

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 September 30, 2023 and December 31, 2022. 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. 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 the Company’s 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 September 30, 2023 and December 31, 2022. 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 September 30, 2023 or December 31, 2022. The following tables present the assets and liabilities reported on the consolidated statements of financial condition at their fair values as of September 30, 2023 and December 31, 2022, by level within the fair value hierarchy (in thousands): Fair Value Measurements at Reporting Date Using: September 30, 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 $ 245,327 245,327 — — Agency obligations 28,248 — 28,248 — Mortgage-backed securities 1,263,144 — 1,263,144 — Asset-backed securities 33,514 — 33,514 — State and municipal obligations 52,040 — 52,040 — Corporate obligations 34,032 — 34,032 — Total available for sale debt securities 1,656,305 245,327 1,410,978 — Equity securities 1,210 1,210 — — Derivative assets 151,103 — 151,103 — $ 1,808,618 246,537 1,562,081 — Derivative liabilities $ 129,271 — 129,271 — Measured on a non-recurring basis: Loans measured for impairment based on the fair value of the underlying collateral $ 7,017 — — 7,017 Foreclosed assets 16,487 — — 16,487 $ 23,504 — — 23,504 Fair Value Measurements at Reporting Date Using: December 31, 2022 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 $ 245,816 245,816 — — Mortgage-backed securities 1,427,139 — 1,427,139 — Asset-backed securities 37,621 — 37,621 — State and municipal obligations 56,864 — 56,864 — Corporate obligations 36,108 — 36,108 — Total available for sale debt securities 1,803,548 245,816 1,557,732 — Equity Securities 1,147 1,147 — — Derivative assets 148,151 — 148,151 — $ 1,952,846 246,963 1,705,883 — Derivative liabilities $ 120,896 — 120,896 — Measured on a non-recurring basis: Loans measured for impairment based on the fair value of the underlying collateral $ 23,988 — — 23,988 Foreclosed assets 2,124 — — 2,124 $ 26,112 — — 26,112 There were no transfers into or out of Level 3 during the three and nine months ended September 30, 2023. 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. At September 30, 2023 and December 31, 2022, $70,000 was included in cash and cash equivalents, representing cash collateral pledged to secure loan level swaps, risk participation agreements and reserves required by banking regulations. 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 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 September 30, 2023 and December 31, 2022. Fair values are presented by level within the fair value hierarchy.

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. At September 30, 2023 and December 31, 2022, the Company had 152 loan related interest rate swaps with aggregate notional amounts of $2.22 billion and $2.40 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 September 30, 2023 and December 31, 2022, the Company had 12 and 14 credit derivatives, respectively, with aggregate notional amounts of $143.3 million and $157.9 million, respectively, from participations in interest rate swaps as part of these loan participation arrangements. At September 30, 2023, the asset and liability positions of these fair value credit derivatives totaled $9,000 and $4,000, respectively, compared to $26,000 and $12,000, respectively, at December 31, 2022. 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 its 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 and nine months ended September 30, 2023 and 2022, such derivatives were used to hedge the variable cash outflows associated with FHLBNY borrowings and brokered demand deposits. 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 $15.5 million will be reclassified as a reduction to interest expense. At September 30, 2023, the Company had 9 outstanding interest rate derivatives with an aggregate notional amount of $455.0 million that were each designated as a cash flow hedge of interest rate risk, compared to 11 outstanding interest rate derivatives with an aggregate notional amount of $460.0 million, at December 31, 2022. 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. The Company does not offset asset and liabilities under such arrangements in the Consolidated Statements of Financial Condition. The tables below present a gross presentation, the effects of offsetting, and a net presentation of the Company’s financial instruments that are eligible for offset in the Consolidated Statements of Condition at September 30, 2023 and December 31, 2022 (in thousands).

In addition, the Company has agreements with certain of its dealer counterparties which contain a provision that if the Company fails to maintain its status as a well or adequately capitalized institution, then the counterparty could terminate the derivative positions and the Company would be required to settle its obligations under the agreements.

Revenue Recognition

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 both the three and nine months ended September 30, 2023, the out-of-scope revenue related to financial instruments was 89.1% and 88.1% of the Company's total revenue, compared to 81.1% and 82.56% for the three and nine months ended September 30, 2022, 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 and nine months ended September 30, 2023 and 2022 (in thousands): Three months ended September 30, Nine months ended September 30, 2023 2022 2023 2022 Non-interest income In-scope of Topic 606: Wealth management fees $ 6,992 6,785 20,826 21,274 Insurance agency income 3,224 2,865 11,175 9,135 Banking service charges and other fees: Service charges on deposit accounts 3,234 3,288 9,647 9,321 Debit card and ATM fees 745 756 2,210 2,372 Total banking service charges and other fees 3,979 4,044 11,857 11,693 Total in-scope non-interest income 14,195 13,694 43,858 42,102 Total out-of-scope non-interest income 5,125 14,751 17,003 27,421 Total non-interest income $ 19,320 28,445 60,861 69,523 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 ("AUM") 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 are 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 are 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.

Leases	Leases The following table represents the consolidated statements of financial condition classification of the Company’s right-of use-assets and lease liabilities at September 30, 2023 and December 31, 2022 (in thousands): Classification September 30, 2023 December 31, 2022 Lease Right-of-Use Assets: Operating lease right-of-use assets Other assets $ 59,031 60,577 Lease Liabilities: Operating lease liabilities Other liabilities $ 62,184 63,372 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. At September 30, 2023, the weighted-average remaining lease term and the weighted-average discount rate for the Company's operating leases were 8.1 years and 2.72%, respectively. The following tables represent lease costs and other lease information for the Company's operating leases.

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 and nine months ended September 30, 2023 are not necessarily indicative of the results of operations that may be expected for all of 2023.
Loans Receivable and Allowance for Credit Losses	Loans Receivable and Allowance for Credit LossesThe 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 and nine months ended September 30, 2023, a worsened economic forecast and related deterioration in the projected commercial property price indices over the expected life of the loan portfolio within our CECL model led to increases to the provisions for credit losses and 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. At September 30, 2023, the Company performed an analysis 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	Accounting Pronouncements Adopted This Year In March 2022, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2022-02, "Financial Instruments-Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures," which addresses areas identified by the FASB as part of its post-implementation review of the credit losses standard (ASU 2016-13) that introduced the CECL model. The amendments eliminate the accounting guidance for troubled debt restructurings by creditors that have adopted the CECL model and enhance the disclosure requirements for loan refinancing and restructurings made with borrowers experiencing financial difficulty. In addition, the amendments require a public business entity to disclose current-period gross write-offs for financing receivables and net investment in leases by year of origination in the vintage disclosures. For entities that have adopted ASU 2016-13, ASU 2022-02 was effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. Early adoption was permitted if an entity had adopted ASU 2016-13. The Company adopted this ASU on January 1, 2023 using the modified retrospective method for all financial assets measured at amortized cost. Results for reporting periods beginning after January 1, 2023 are presented under ASC 326 while prior period amounts continue to be recorded with previously applicable GAAP. 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. In March 2022, the FASB issued Accounting Standards Update (ASU) 2022-01, Derivatives and Hedging (Topic 815): Fair Value Hedging – Portfolio Layer Method . The purpose of this updated guidance is to further align risk management objectives with hedge accounting results on the application of the last-of-layer method, which was first introduced in ASU 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities. ASU 2022-01 is effective for public business entities for fiscal years beginning after December 15, 2022, 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. In March 2020, the FASB issued ASU 2020-04, "Reference Rate Reform (Topic 848)," which provides optional expedients and exceptions for applying GAAP to loan and lease agreements, derivative contracts, and other transactions affected by the anticipated transition away from LIBOR toward new interest rate benchmarks. For transactions that are modified because of reference rate reform and that meet certain scope guidance: (i) modifications of loan agreements should be accounted for by prospectively adjusting the effective interest rate and the modification will be considered "minor" so that any existing unamortized origination fees/costs would carry forward and continue to be amortized; and (ii) modifications of lease agreements should be accounted for as a continuation of the existing agreement with no reassessments of the lease classification and the discount rate or re-measurements of lease payments that otherwise would be required for modifications not accounted for as separate contracts. ASU 2020-04 also provides numerous optional expedients for derivative accounting. In addition, in January 2021, the FASB issued ASU No. 2021-01 “Reference Rate Reform — Scope,” which clarified the scope of ASC 848 relating to contract modifications. The Company has reviewed all of its LIBOR-based products and all products have been adjusted to another index or are scheduled to be adjusted at their next repricing, as LIBOR ceased to be published after June 30,
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 September 30, 2023 and December 31, 2022. 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. 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 the Company’s 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 September 30, 2023 and December 31, 2022. 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
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 ("AUM") 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 are 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 are 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.

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.
