Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Principles of Consolidation The consolidated financial statements include the accounts of Provident Financial Services, Inc. (the “Company”), Provident Bank (the “Bank”) and their wholly owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. Certain reclassifications have been made in the consolidated financial statements to conform with current year classifications. Business The Company, through the Bank, provides a full range of banking services to individual and business customers through branch offices in New Jersey and eastern Pennsylvania. The Bank is subject to competition from other financial institutions and to the regulations of certain federal and state agencies, and undergoes periodic examinations by those regulatory authorities. Basis of Financial Statement Presentation The consolidated financial statements of the Company have been prepared in conformity with U.S. generally accepted accounting principles (“GAAP”). In preparing the consolidated financial statements, management is required to make estimates and assumptions about future events. These estimates and the underlying assumptions affect the reported amounts of assets and liabilities and disclosures about contingent assets and liabilities as of the dates of the consolidated statements of financial condition, and revenues and expenses for the periods then ended. Such estimates are used in connection with the determination of the allowance for loan losses, evaluation of goodwill for impairment, evaluation of other-than-temporary impairment on securities, evaluation of the need for valuation allowances on deferred tax assets, and determination of liabilities related to retirement and other post-retirement benefits, among others. These estimates and assumptions are based on management’s best estimates and judgment. Management evaluates its estimates and assumptions on an ongoing basis using historical experience and other factors, including the current economic environment, which management believes to be reasonable under the circumstances. Such estimates and assumptions are adjusted when facts and circumstances dictate. Illiquid credit markets, volatile securities markets, and declines in the housing market and the economy generally have combined to increase the uncertainty inherent in such estimates and assumptions. As future events and their effects cannot be determined with precision, actual results could differ significantly from these estimates. Changes in estimates resulting from continuing changes in the economic environment will be reflected in the financial statements in future periods. Cash and Cash Equivalents For purposes of reporting cash flows, cash and cash equivalents include cash and due from banks, Federal funds sold and commercial paper with original maturity dates less than 90 days. Securities Securities include held to maturity debt securities and available for sale debt securities. The available for sale debt securities portfolio is carried at estimated fair value, with any unrealized gains or losses, net of taxes, reported as accumulated other comprehensive income or loss in Stockholders’ Equity. Estimated fair values are based on market quotations or matrix pricing. Securities which the Company has the positive intent and ability to hold to maturity are classified as held to maturity debt securities and carried at amortized cost. Management conducts a periodic review and evaluation of the securities portfolio to determine if any declines in the fair values of securities are other-than-temporary. In this evaluation, if such a decline were deemed other-than-temporary, management would measure the total credit-related component of the unrealized loss, and recognize that portion of the loss as a charge to current period earnings. The remaining portion of the unrealized loss would be recognized as an adjustment to accumulated other comprehensive income (loss). The fair value of the securities portfolio is significantly affected by changes in interest rates. In general, as interest rates rise, the fair value of fixed-rate securities decreases and as interest rates fall, the fair value of fixed-rate securities increases. The Company determines if it has the intent to sell these securities or if it is more likely than not that the Company would be required to sell the securities before the anticipated recovery. If either exists, the entire decline in value is considered other-than-temporary and would be recognized as an expense in the current period. Premiums on securities are amortized to income using a method that approximates the interest method over the remaining period to the earliest call date or contractual maturity, adjusted for anticipated prepayments. Discounts on securities are accreted to income over the remaining period to the contractual maturity, adjusted for anticipated prepayments.. Dividend and interest income are recognized when earned. Realized gains and losses are recognized when securities are sold or called based on the specific identification method. Fair Value of Financial Instruments 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). 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. Federal Home Loan Bank of New York Stock The Bank, as a member of the Federal Home Loan Bank of New York (“FHLBNY”), is required to hold shares of capital stock of the FHLBNY at cost based on a specified formula. The Bank carries this investment at cost, which approximates fair value. Loans Loans receivable are carried at unpaid principal balances plus unamortized premiums, purchase accounting mark-to-market adjustments, certain deferred direct loan origination costs and deferred loan origination fees and discounts, less the allowance for loan losses. The Bank defers loan origination fees and certain direct loan origination costs and accretes or amortizes such amounts as an adjustment to the yield over the expected lives of the related loans using the interest method. Premiums and discounts on loans purchased are amortized or accreted as an adjustment of yield over the contractual lives of the related loans, adjusted for prepayments when applicable, using methodologies which approximate the interest method. Loans are generally placed on non-accrual status when they are past due 90 days or more as to contractual obligations or when other circumstances indicate that collection is questionable. When a loan is placed on non-accrual status, any interest accrued but not received is reversed against interest income. Payments received on a non-accrual loan are either applied to the outstanding principal balance or recorded as interest income, depending on an assessment of the ability to collect the loan. A non-accrual loan is restored to accrual status when principal and interest payments become less than 90 days past due and its future collectability is reasonably assured. An impaired loan is defined as a loan for which it is probable, based on current information, that the Bank will not collect all amounts due under the contractual terms of the loan agreement. Impaired loans are individually assessed to determine that each loan’s carrying value is not in excess of the fair value of the related collateral or the present value of the expected future cash flows. Residential mortgage and consumer loans are deemed smaller balance homogeneous loans which are evaluated collectively for impairment and are therefore excluded from the population of impaired loans. Purchased Credit-Impaired (“PCI”) loans, are loans acquired at a discount primarily due to deteriorated credit quality. PCI loans are recorded at fair value at the date of acquisition, with no allowance for loan losses. The difference between the undiscounted cash flows expected at acquisition and the fair value of the PCI loans at acquisition represents the accretable yield and is recognized as interest income over the life of the loans. Contractually required payments for interest and principal that exceed the undiscounted cash flows expected at acquisition represent the non-accretable discount and are not recognized as a yield adjustment or a valuation allowance. Reclassifications of the non-accretable to accretable yield may occur subsequent to the loan acquisition dates due to an increase in expected cash flows of the loans and results in an increase in interest income on a prospective basis. Allowance for Loan Losses Losses on loans are charged to the allowance for loan losses. Additions to this allowance are made by recoveries of loans previously charged off and by a provision charged to expense. The determination of the balance of the allowance for loan losses is based on an analysis of the loan portfolio, economic conditions, historical loan loss experience and other factors that warrant recognition in providing for an adequate allowance. While management uses available information to recognize losses on loans, future additions to the allowance for loan losses may be necessary based on changes in economic conditions in the Bank’s market area. In addition, various regulatory agencies, as an integral part of their examination process, periodically review the Bank’s allowance for loan losses. Such agencies may require the Bank to recognize additions to the allowance or additional write-downs based on their judgments about information available to them at the time of their examination. Foreclosed Assets Assets acquired through foreclosure or deed in lieu of foreclosure are carried at the lower of the outstanding loan balance at the time of foreclosure or fair value, less estimated costs to sell. Fair value is generally based on recent appraisals. When an asset is acquired, the excess of the loan balance over fair value, less estimated costs to sell, is charged to the allowance for loan 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. Banking Premises and Equipment Land is carried at cost. Banking premises, furniture, fixtures and equipment are carried at cost, less accumulated depreciation, computed using the straight-line method based on their estimated useful lives. Leasehold improvements, carried at cost, net of accumulated depreciation, are amortized over the terms of the leases or the estimated useful lives of the assets, whichever are shorter, using the straight-line method. Maintenance and repairs are charged to expense as incurred. Income Taxes The Company uses the asset and liability method of accounting for income taxes. Under this method, deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates in effect for the year in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in tax expense in the period that includes the enactment date. Deferred tax assets and liabilities are reported as a component of other assets on the Consolidated Statements of Financial Condition. The determination of whether deferred tax assets will be realizable is predicated on estimates of future taxable income. Such estimates are subject to management’s judgment. A valuation reserve is established when management is unable to conclude that it is more likely than not that it will realize deferred tax assets based on the nature and timing of these items. The Company recognizes, when applicable, interest and penalties related to unrecognized tax benefits in the provision for income taxes. Trust Assets Trust assets consisting of securities and other property (other than cash on deposit held by the Bank in fiduciary or agency capacities for customers of the Bank’s wholly owned subsidiary, Beacon) are not included in the accompanying consolidated statements of financial condition because such properties are not assets of the Bank. Intangible Assets Intangible assets of the Bank consist of goodwill, core deposit premiums, customer relationship premium and mortgage servicing rights. Goodwill 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 each year at September 30th. 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 annual goodwill impairment test as of September 30, 2019. Based upon its qualitative assessment of goodwill, the Company concluded that goodwill was not impaired and no further quantitative analysis was warranted. Core deposit premiums represent the intangible value of depositor relationships assumed in purchase acquisitions and are amortized on an accelerated basis over 8.8 years. Customer relationship premiums represent the intangible value of customer relationships assumed in the purchase acquisitions of Beacon Trust Company ("Beacon"), The MDE Group, Inc. ("MDE") and Tirschwell & Loewy, Inc. ("T&L"), and are amortized on an accelerated basis over 12.0 years, 10.4 years and 10.0 years, respectively. Mortgage servicing rights are recorded when purchased or when originated mortgage loans are sold, with servicing rights retained. Mortgage servicing rights are amortized on an accelerated method based upon the estimated lives of the related loans, adjusted for prepayments. Mortgage servicing rights are carried at the lower of amortized cost or fair value. Bank-owned Life Insurance Bank-owned life insurance is accounted for using the cash surrender value method and is recorded at its realizable value. Employee Benefit Plans The Bank maintains a pension plan which covers full-time employees hired prior to April 1, 2003, the date on which the pension plan was frozen. The Bank’s policy is to fund at least the minimum contribution required by the Employee Retirement Income Security Act of 1974. GAAP requires an employer to: (a) recognize in its statement of financial position the over-funded or under-funded status of a defined benefit postretirement plan measured as the difference between the fair value of plan assets and the benefit obligation; (b) measure a plan’s assets and its obligations that determine its funded status at the end of the employer’s fiscal year (with limited exceptions); and (c) recognize as a component of other comprehensive income, net of tax, the actuarial gains and losses and the prior service costs and credits that arise during the period. The Bank has a 401(k) plan covering substantially all employees of the Bank. The Bank may match a percentage of the first 6% contributed by participants. The Bank’s matching contribution, if any, is determined by the Board of Directors in its sole discretion. The Bank has an Employee Stock Ownership Plan (“ESOP”). The funds borrowed by the ESOP from the Company to purchase the Company’s common stock are being repaid from the Bank’s contributions and dividends paid on unallocated ESOP shares over a period of up to 30 years. The Company’s common stock not allocated to participants is recorded as a reduction of stockholders’ equity at cost. Compensation expense for the ESOP is based on the average price of the Company’s stock during each quarter and the amount of shares allocated during the quarter. The Bank has an Equity Plan designed to provide competitive compensation for demonstrated performance and to align the interests of participants directly to increases in shareholder value. The Equity Plan provides for performance-vesting grants as well as time-vesting grants. Time-vesting stock awards, stock options and performance vesting stock awards that are based on a performance condition, such as return on average assets are valued on the closing stock price on the date of grant. Performance vesting stock awards and options that are based on a market condition, such as Total Shareholder Return, would be valued using a generally accepted statistical technique to simulate future stock prices for Provident and the components of the Peer Group which Provident would be measured against. Expense related to time vesting stock awards and stock options is based on the fair value of the common stock on the date of the grant and on the fair value of the stock options on the date of the grant, respectively, and is recognized ratably over the vesting period of the awards. Performance vesting stock awards and stock options are either dependent upon a market condition or a performance condition. A market condition performance metric is tied to a stock price, either on an absolute basis, or a relative basis against peers, while a performance-condition is based on internal operations, such as earnings per share. The expense related to a market condition performance-vesting stock award or stock option requires an initial Monte Carlo simulation to determine grant date fair value, which will be recognized as a compensation expense regardless of actual payout, assuming that the executive is still employed at the end of the requisite service period. If pre-vesting termination (forfeiture) occurs, then any expense recognized to date can be reversed. The grant date fair value is recognized ratably over the performance period. The expense related to a performance condition stock award or stock option is based on the fair value of the award on the date of grant, adjusted periodically based upon the number of awards or options expected to be earned, recognized over the performance period. In connection with the First Sentinel acquisition in July 2004, the Company assumed the First Savings Bank Directors’ Deferred Fee Plan (the “DDFP”). The DDFP was frozen prior to the acquisition. The Company recorded a deferred compensation equity instrument and corresponding contra-equity account for the value of the shares held by the DDFP at the July 14, 2004 acquisition date. These accounts will be liquidated as shares are distributed from the DDFP in accordance with the plan document. At December 31, 2019, there were 219,281 shares held by the DDFP. The Bank maintains a non-qualified plan that provides supplemental benefits to certain executives who are prevented from receiving the full benefits contemplated by the 401(k) Plan’s and the ESOP’s benefit formulas under tax law limits for tax-qualified plans. Post-retirement Benefits Other Than Pensions The Bank provides post-retirement health care and life insurance plans to certain of its employees. The life insurance coverage is noncontributory to the participant. Participants contribute to the cost of medical coverage based on the employee’s length of service with the Bank. 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. On December 31, 2002, the Bank eliminated postretirement healthcare benefits for employees with less than 10 years of service. GAAP requires an employer to: (a) recognize in its statement of financial position the over-funded or under-funded status of a defined benefit post-retirement plan measured as the difference between the fair value of plan assets and the benefit obligation; (b) measure a plan’s assets and its obligations that determine its funded status as of the end of the employer’s fiscal year (with limited exceptions); and (c) recognize as a component of other comprehensive income, net of tax, the actuarial gains and losses and the prior service costs and credits that arise during the period. 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 and, therefore, are not used to manage interest rate risk in the Company’s assets or liabilities. As such, all changes in fair value of the Company’s interest rate derivatives not used to manage interest rate risk 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 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. 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 income and are subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. These derivatives were used to hedge the variable cash outflows associated with Federal Home Loan Bank borrowings. 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. Comprehensive Income Comprehensive income is divided into net income and other comprehensive income (loss). Other comprehensive income (loss) includes items previously recorded directly to equity, such as unrealized gains and losses on available for sale debt securities, unrealized gains and losses on derivatives and amortization related to post-retirement obligations. Comprehensive income is presented in a separate Consolidated Statement of Comprehensive Income. Segment Reporting The Company’s operations are solely in the financial services industry and include providing traditional banking and other financial services to its customers. The Company operates primarily in the geographical regions of northern and central New Jersey and eastern Pennsylvania. Management makes operating decisions and assesses performance based on an ongoing review of the Bank’s consolidated financial results. Therefore, the Company has a single operating segment for financial reporting purposes. Earnings Per Share Basic earnings per share is computed by dividing income available to common stockholders by the weighted average number of shares outstanding for the period. Diluted earnings per share reflects the potential dilution that could occur if securities or other contracts to issue common stock (such as stock options) were exercised or resulted in the issuance of common stock. These potentially dilutive shares would then be included in the weighted average number of shares outstanding for the period using the treasury stock method. Shares issued and shares reacquired during the period are weighted for the portion of the period that they were outstanding. Impact of Recent Accounting Pronouncements Accounting Pronouncements Adopted in 2019 In October 2018, the Financial Accounting Standards Board ("FASB") issued ASU No. 2018-16, “Derivatives and Hedging (Topic 815) – Inclusion of the Secured Overnight Financing Rate (SOFR) Overnight Index Swap (OIS) Rate as a Benchmark Interest Rate for Hedge Accounting Purposes.” This ASU permits the use of the OIS rate based upon SOFR as a U.S. benchmark interest rate for hedge accounting purposes under Topic 815 in addition to the UST, the LIBOR swap rate, the OIS rate based on the Fed Funds Effective Rate, and the SIFMA Municipal Swap Rate. The amendments in ASU 2018-16 are required to be adopted concurrently with ASU 2017-12, "Derivatives and Hedging: Targeted Improvements to Accounting for Hedging," which was effective for public business entities for fiscal years beginning after December 15, 2018, with early adoption, including adoption in an interim period, permitted. ASU 2018-16 should be adopted on a prospective basis for qualifying new or redesignated hedging relationships entered into on or after the date of adoption. The Company adopted this guidance effective January 1, 2019. The adoption of this guidance had no impact on the Company’s consolidated financial statements. In August 2017, the FASB issued ASU 2017-12, "Derivatives and Hedging: Targeted Improvements to Accounting for Hedging." The purpose of this updated guidance is to better align a company’s financial reporting for hedging activities with the economic objectives of those activities. ASU 2017-12 was effective for public business entities for fiscal years beginning after December 15, 2018. ASU 2017-12 requires a modified retrospective transition method in which the Company will recognize the cumulative effect of the change on the opening balance of each affected component of equity in the statement of financial position as of the date of adoption. The Company adopted this guidance effective January 1, 2019. The adoption of this guidance had no impact on the Company’s consolidated financial statements. In March 2017, the FASB issued ASU 2017-08, “Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities.” This ASU shortens the amortization period for premiums on callable debt securities by requiring that premiums be amortized to the first (or earliest) call date instead of as an adjustment to the yield over the contractual life. This change more closely aligns the accounting with the economics of a callable debt security and the amortization period with expectations that already are included in market pricing on callable debt securities. This ASU does not change the accounting for discounts on callable debt securities, which will continue to be amortized to the maturity date. This guidance only includes instruments that are held at a premium and have explicit call features. It does not include instruments that contain prepayment features, such as mortgage backed securities; nor does it include call options that are contingent upon future events or in which the timing or amount to be paid is not fixed. This ASU was effective for fiscal years beginning after December 15, 2018, including interim periods within the reporting period, with early adoption permitted. The Company adopted this guidance effective January 1, 2019. The adoption of this guidance had no impact on the Company’s consolidated financial statements. In February 2016, the FASB issued ASU 2016-02, "Leases (Topic 842).” This ASU requires all lessees to recognize a lease liability and a right-of-use asset, measured at the present value of the future minimum lease payments, at the lease commencement date. Lessor accounting remains largely unchanged under the new guidance. The guidance is effective for fiscal years beginning after December 15, 2018, including interim reporting periods within that reporting period, with early adoption permitted. A modified retrospective approach must be applied for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. In July 2018, the FASB issued ASU No. 2018-11, “Leases - Targeted Improvements” to provide entities with relief from the costs of implementing certain aspects of ASU No. 2016-02. Specifically, under the amendments in ASU 2018-11: (1) entities may elect not to recast the comparative periods presented when transitioning to the new leasing standard, and (2) lessors may elect not to separate lease and non-lease components when certain conditions are met. The amendments have the same effective date as ASU 2016-02. In the first quarter of 2018, the Company formed a working group to guide the implementation efforts, including the identification and review of all lease agreements within the scope of the guidance. The working group has identified the inventory of leases and actively accumulated the requisite lease data necessary to apply the guidance. Also, the working group purchased and implemented a software platform to properly record and track all leases, monitor right-of-use assets and lease liabilities and support all accounting and disclosure requirements of the guidance. The Company adopted both ASU No. 2016-02 and ASU No. 2018-11 effective January 1, 2019 and elected to apply the guidance as of the beginning of the period of adoption (January 1, 2019) and not restate comparative periods. The Company also elected certain optional practical expedients, which allow the Company to forego a reassessment of (1) whether any expired or existing contracts are or contain leases, (2) the lease classification for any expired or existing leases, and (3) the initial direct costs for any existing leases. The adoption of the new standard resulted in the Company recording a right-of-use and an additional lease liability on its consolidated statement of financial condition of $44.9 million and $46.1 million, respectively, based on the present value of the expected remaining lease payments at January 1, 2019. It also resulted in additional footnote disclosures (see Note 22 - "Leases").

The consolidated financial statements of the Company have been prepared in conformity with U.S. generally accepted accounting principles (“GAAP”). In preparing the consolidated financial statements, management is required to make estimates and assumptions about future events. These estimates and the underlying assumptions affect the reported amounts of assets and liabilities and disclosures about contingent assets and liabilities as of the dates of the consolidated statements of financial condition, and revenues and expenses for the periods then ended. Such estimates are used in connection with the determination of the allowance for loan losses, evaluation of goodwill for impairment, evaluation of other-than-temporary impairment on securities, evaluation of the need for valuation allowances on deferred tax assets, and determination of liabilities related to retirement and other post-retirement benefits, among others. These estimates and assumptions are based on management’s best estimates and judgment. Management evaluates its estimates and assumptions on an ongoing basis using historical experience and other factors, including the current economic environment, which management believes to be reasonable under the circumstances. Such estimates and assumptions are adjusted when facts and circumstances dictate. Illiquid credit markets, volatile securities markets, and declines in the housing market and the economy generally have combined to increase the uncertainty inherent in such estimates and assumptions. As future events and their effects cannot be determined with precision, actual results could differ significantly from these estimates. Changes in estimates resulting from continuing changes in the economic environment will be reflected in the financial statements in future periods.

Securities include held to maturity debt securities and available for sale debt securities. The available for sale debt securities portfolio is carried at estimated fair value, with any unrealized gains or losses, net of taxes, reported as accumulated other comprehensive income or loss in Stockholders’ Equity. Estimated fair values are based on market quotations or matrix pricing. Securities which the Company has the positive intent and ability to hold to maturity are classified as held to maturity debt securities and carried at amortized cost. Management conducts a periodic review and evaluation of the securities portfolio to determine if any declines in the fair values of securities are other-than-temporary. In this evaluation, if such a decline were deemed other-than-temporary, management would measure the total credit-related component of the unrealized loss, and recognize that portion of the loss as a charge to current period earnings. The remaining portion of the unrealized loss would be recognized as an adjustment to accumulated other comprehensive income (loss). The fair value of the securities portfolio is significantly affected by changes in interest rates. In general, as interest rates rise, the fair value of fixed-rate securities decreases and as interest rates fall, the fair value of fixed-rate securities increases. The Company determines if it has the intent to sell these securities or if it is more likely than not that the Company would be required to sell the securities before the anticipated recovery. If either exists, the entire decline in value is considered other-than-temporary and would be recognized as an expense in the current period.

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). 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.

Loans are generally placed on non-accrual status when they are past due 90 days or more as to contractual obligations or when other circumstances indicate that collection is questionable. When a loan is placed on non-accrual status, any interest accrued but not received is reversed against interest income. Payments received on a non-accrual loan are either applied to the outstanding principal balance or recorded as interest income, depending on an assessment of the ability to collect the loan. A non-accrual loan is restored to accrual status when principal and interest payments become less than 90 days past due and its future collectability is reasonably assured.

An impaired loan is defined as a loan for which it is probable, based on current information, that the Bank will not collect all amounts due under the contractual terms of the loan agreement. Impaired loans are individually assessed to determine that each loan’s carrying value is not in excess of the fair value of the related collateral or the present value of the expected future cash flows. Residential mortgage and consumer loans are deemed smaller balance homogeneous loans which are evaluated collectively for impairment and are therefore excluded from the population of impaired loans.

Purchased Credit-Impaired (“PCI”) loans, are loans acquired at a discount primarily due to deteriorated credit quality. PCI loans are recorded at fair value at the date of acquisition, with no allowance for loan losses. The difference between the undiscounted cash flows expected at acquisition and the fair value of the PCI loans at acquisition represents the accretable yield and is recognized as interest income over the life of the loans. Contractually required payments for interest and principal that exceed the undiscounted cash flows expected at acquisition represent the non-accretable discount and are not recognized as a yield adjustment or a valuation allowance. Reclassifications of the non-accretable to accretable yield may occur subsequent to the loan acquisition dates due to an increase in expected cash flows of the loans and results in an increase in interest income on a prospective basis.

Assets acquired through foreclosure or deed in lieu of foreclosure are carried at the lower of the outstanding loan balance at the time of foreclosure or fair value, less estimated costs to sell. Fair value is generally based on recent appraisals. When an asset is acquired, the excess of the loan balance over fair value, less estimated costs to sell, is charged to the allowance for loan 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.

Land is carried at cost. Banking premises, furniture, fixtures and equipment are carried at cost, less accumulated depreciation, computed using the straight-line method based on their estimated useful lives. Leasehold improvements, carried at cost, net of accumulated depreciation, are amortized over the terms of the leases or the estimated useful lives of the assets, whichever are shorter, using the straight-line method. Maintenance and repairs are charged to expense as incurred.

The Company uses the asset and liability method of accounting for income taxes. Under this method, deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates in effect for the year in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in tax expense in the period that includes the enactment date. Deferred tax assets and liabilities are reported as a component of other assets on the Consolidated Statements of Financial Condition. The determination of whether deferred tax assets will be realizable is predicated on estimates of future taxable income. Such estimates are subject to management’s judgment. A valuation reserve is established when management is unable to conclude that it is more likely than not that it will realize deferred tax assets based on the nature and timing of these items. The Company recognizes, when applicable, interest and penalties related to unrecognized tax benefits in the provision for income taxes.

Intangible assets of the Bank consist of goodwill, core deposit premiums, customer relationship premium and mortgage servicing rights. Goodwill 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 each year at September 30th. 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 annual goodwill impairment test as of September 30, 2019. Based upon its qualitative assessment of goodwill, the Company concluded that goodwill was not impaired and no further quantitative analysis was warranted.

Core deposit premiums represent the intangible value of depositor relationships assumed in purchase acquisitions and are amortized on an accelerated basis over 8.8 years. Customer relationship premiums represent the intangible value of customer relationships assumed in the purchase acquisitions of Beacon Trust Company ("Beacon"), The MDE Group, Inc. ("MDE") and Tirschwell & Loewy, Inc. ("T&L"), and are amortized on an accelerated basis over 12.0 years, 10.4 years and 10.0 years,

The Bank maintains a pension plan which covers full-time employees hired prior to April 1, 2003, the date on which the pension plan was frozen. The Bank’s policy is to fund at least the minimum contribution required by the Employee Retirement Income Security Act of 1974. GAAP requires an employer to: (a) recognize in its statement of financial position the over-funded or under-funded status of a defined benefit postretirement plan measured as the difference between the fair value of plan assets and the benefit obligation; (b) measure a plan’s assets and its obligations that determine its funded status at the end of the employer’s fiscal year (with limited exceptions); and (c) recognize as a component of other comprehensive income, net of tax, the actuarial gains and losses and the prior service costs and credits that arise during the period.

The Bank has an Employee Stock Ownership Plan (“ESOP”). The funds borrowed by the ESOP from the Company to purchase the Company’s common stock are being repaid from the Bank’s contributions and dividends paid on unallocated ESOP shares over a period of up to 30 years. The Company’s common stock not allocated to participants is recorded as a reduction of stockholders’ equity at cost. Compensation expense for the ESOP is based on the average price of the Company’s stock during each quarter and the amount of shares allocated during the quarter.

The Bank has an Equity Plan designed to provide competitive compensation for demonstrated performance and to align the interests of participants directly to increases in shareholder value. The Equity Plan provides for performance-vesting grants as well as time-vesting grants. Time-vesting stock awards, stock options and performance vesting stock awards that are based on a performance condition, such as return on average assets are valued on the closing stock price on the date of grant. Performance vesting stock awards and options that are based on a market condition, such as Total Shareholder Return, would be valued using a generally accepted statistical technique to simulate future stock prices for Provident and the components of the Peer Group which Provident would be measured against.

Expense related to time vesting stock awards and stock options is based on the fair value of the common stock on the date of the grant and on the fair value of the stock options on the date of the grant, respectively, and is recognized ratably over the vesting period of the awards. Performance vesting stock awards and stock options are either dependent upon a market condition or a performance condition. A market condition performance metric is tied to a stock price, either on an absolute basis, or a relative basis against peers, while a performance-condition is based on internal operations, such as earnings per share. The expense related to a market condition performance-vesting stock award or stock option requires an initial Monte Carlo simulation to determine grant date fair value, which will be recognized as a compensation expense regardless of actual payout, assuming that the executive is still employed at the end of the requisite service period. If pre-vesting termination (forfeiture) occurs, then any expense recognized to date can be reversed. The grant date fair value is recognized ratably over the performance period. The expense related to a performance condition stock award or stock option is based on the fair value of the award on the date of grant, adjusted periodically based upon the number of awards or options expected to be earned, recognized over the performance period.

In connection with the First Sentinel acquisition in July 2004, the Company assumed the First Savings Bank Directors’ Deferred Fee Plan (the “DDFP”). The DDFP was frozen prior to the acquisition. The Company recorded a deferred compensation equity instrument and corresponding contra-equity account for the value of the shares held by the DDFP at the July 14, 2004 acquisition date. These accounts will be liquidated as shares are distributed from the DDFP in accordance with the plan document. At December 31, 2019, there were 219,281 shares held by the DDFP.

The Bank provides post-retirement health care and life insurance plans to certain of its employees. The life insurance coverage is noncontributory to the participant. Participants contribute to the cost of medical coverage based on the employee’s length of service with the Bank. 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. On December 31, 2002, the Bank eliminated postretirement healthcare benefits for employees with less than 10 years of service. GAAP requires an employer to: (a) recognize in its statement of financial position the over-funded or under-funded status of a defined benefit post-retirement plan measured as the difference between the fair value of plan assets and the benefit obligation; (b) measure a plan’s assets and its obligations that determine its funded status as of the end of the employer’s fiscal year (with limited exceptions); and (c) recognize as a component of other comprehensive income, net of tax, the actuarial gains and losses and the prior service costs and credits that arise during the period.

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 and, therefore, are not used to manage interest rate risk in the Company’s assets or liabilities. As such, all changes in fair value of the Company’s interest rate derivatives not used to manage interest rate risk 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 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. 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 income and are subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. These derivatives were used to hedge the variable cash outflows associated with Federal Home Loan Bank borrowings.

The Company’s operations are solely in the financial services industry and include providing traditional banking and other financial services to its customers. The Company operates primarily in the geographical regions of northern and central New Jersey and eastern Pennsylvania. Management makes operating decisions and assesses performance based on an ongoing review of the Bank’s consolidated financial results. Therefore, the Company has a single operating segment for financial reporting purposes.

Basic earnings per share is computed by dividing income available to common stockholders by the weighted average number of shares outstanding for the period. Diluted earnings per share reflects the potential dilution that could occur if securities or other contracts to issue common stock (such as stock options) were exercised or resulted in the issuance of common stock. These potentially dilutive shares would then be included in the weighted average number of shares outstanding for the period using the treasury stock method. Shares issued and shares reacquired during the period are weighted for the portion of the period that they were outstanding.

In October 2018, the Financial Accounting Standards Board ("FASB") issued ASU No. 2018-16, “Derivatives and Hedging (Topic 815) – Inclusion of the Secured Overnight Financing Rate (SOFR) Overnight Index Swap (OIS) Rate as a Benchmark Interest Rate for Hedge Accounting Purposes.” This ASU permits the use of the OIS rate based upon SOFR as a U.S. benchmark interest rate for hedge accounting purposes under Topic 815 in addition to the UST, the LIBOR swap rate, the OIS rate based on the Fed Funds Effective Rate, and the SIFMA Municipal Swap Rate. The amendments in ASU 2018-16 are required to be adopted concurrently with ASU 2017-12, "Derivatives and Hedging: Targeted Improvements to Accounting for Hedging," which was effective for public business entities for fiscal years beginning after December 15, 2018, with early adoption, including adoption in an interim period, permitted. ASU 2018-16 should be adopted on a prospective basis for qualifying new or redesignated hedging relationships entered into on or after the date of adoption. The Company adopted this guidance effective January 1, 2019. The adoption of this guidance had no impact on the Company’s consolidated financial statements.

In August 2017, the FASB issued ASU 2017-12, "Derivatives and Hedging: Targeted Improvements to Accounting for Hedging." The purpose of this updated guidance is to better align a company’s financial reporting for hedging activities with the economic objectives of those activities. ASU 2017-12 was effective for public business entities for fiscal years beginning after December 15, 2018. ASU 2017-12 requires a modified retrospective transition method in which the Company will recognize the cumulative effect of the change on the opening balance of each affected component of equity in the statement of financial position as of the date of adoption. The Company adopted this guidance effective January 1, 2019. The adoption of this guidance had no impact on the Company’s consolidated financial statements.

In March 2017, the FASB issued ASU 2017-08, “Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities.” This ASU shortens the amortization period for premiums on callable debt securities by requiring that premiums be amortized to the first (or earliest) call date instead of as an adjustment to the yield over the contractual life. This change more closely aligns the accounting with the economics of a callable debt security and the amortization period with expectations that already are included in market pricing on callable debt securities. This ASU does not change the accounting for discounts on callable debt securities, which will continue to be amortized to the maturity date. This guidance only includes instruments that are held at a premium and have explicit call features. It does not include instruments that contain prepayment features, such as mortgage backed securities; nor does it include call options that are contingent upon future events or in which the timing or amount to be paid is not fixed. This ASU was effective for fiscal years beginning after December 15, 2018, including interim periods within the reporting period, with early adoption permitted. The Company adopted this guidance effective January 1, 2019. The adoption of this guidance had no impact on the Company’s consolidated financial statements.

In February 2016, the FASB issued ASU 2016-02, "Leases (Topic 842).” This ASU requires all lessees to recognize a lease liability and a right-of-use asset, measured at the present value of the future minimum lease payments, at the lease commencement date. Lessor accounting remains largely unchanged under the new guidance. The guidance is effective for fiscal years beginning after December 15, 2018, including interim reporting periods within that reporting period, with early adoption permitted. A modified retrospective approach must be applied for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. In July 2018, the FASB issued ASU No. 2018-11, “Leases - Targeted Improvements” to provide entities with relief from the costs of implementing certain aspects of ASU No. 2016-02. Specifically, under the amendments in ASU 2018-11: (1) entities may elect not to recast the comparative periods presented when transitioning to the new leasing standard, and (2) lessors may elect not to separate lease and non-lease components when certain conditions are met. The amendments have the same effective date as ASU 2016-02. In the first quarter of 2018, the Company formed a working group to guide the implementation efforts, including the identification and review of all lease agreements within the scope of the guidance. The working group has identified the inventory of leases and actively accumulated the requisite lease data necessary to apply the guidance. Also, the working group purchased and implemented a software platform to properly record and track all leases, monitor right-of-use assets and lease liabilities and support all accounting and disclosure requirements of the guidance. The Company adopted both ASU No. 2016-02 and ASU No. 2018-11 effective January 1, 2019 and elected to apply the guidance as of the beginning of the period of adoption (January 1, 2019) and not restate comparative periods. The Company also elected certain optional practical expedients, which allow the Company to forego a reassessment of (1) whether any expired or existing contracts are or contain leases, (2) the lease classification for any expired or existing leases, and (3) the initial direct costs for any existing leases. The adoption of the new
