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”), The 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”). Certain reclassifications have been made in the consolidated financial statements to conform with current year classifications. 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 maturity dates less than 90 days. Securities Securities include investment securities held to maturity and securities available for sale. Securities that the Company has the positive intent and ability to hold to maturity are classified as “investment securities held to maturity” and reported at amortized cost. Securities to be held for indefinite periods of time and not intended to be held to maturity are classified as “securities available for sale” and are reported at estimated fair value, with unrealized gains and losses excluded from earnings and reported as a separate component of stockholders’ equity, net of deferred taxes. The estimated fair values of the Company’s securities are affected by changes in interest rates, credit spreads, and market illiquidity. The Company 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. To determine if a decline in value is other-than-temporary, the Company evaluates 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 such a decline were deemed other-than-temporary, the Company 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. In general, as interest rates rise, the market value of fixed-rate securities decreases and as interest rates fall, the market value of fixed-rate securities increases. The market for non-investment grade, privately issued mortgage-backed securities remains illiquid and prices have not appreciated despite favorable movements in interest rates. To determine if a decline in value is other-than-temporary, the Company evaluates 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. Premiums and discounts on securities are amortized and accreted to income using a method that approximates the interest method over the remaining period to 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 such amounts as an adjustment to 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 collectibility is reasonably assured. An impaired loan is defined as a loan for which it is probable, based on current information, that the lender 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 (generally 25 to 40 years for buildings, and 3 to 5 years for furniture and equipment). 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 income in the period that includes the enactment date. 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 Trust Company) 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 30 th . 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, 2015. 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 acquisition of Beacon and MDE, and are amortized on an accelerated basis over 12.0 years and 10.4 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, 2015 , there were 372,817 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 Consolidated 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 existing interest rate derivatives result from a service provided to certain qualifying 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 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 Federal Home Loan Bank borrowings. The effective portion of changes in the fair value of these derivatives are recorded in accumulated other comprehensive income, and are subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. The ineffective portion of the change in fair value of these derivatives are recognized directly in earnings. The fair value of the Company's derivatives are determined using discounted cash flow analyses using observable market-based inputs. Comprehensive Income Comprehensive income is divided into net income and other comprehensive income. Other comprehensive income includes items previously recorded directly to equity, such as unrealized gains and losses on securities available for sale, 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 In February 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 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. The Company is currently assessing the impact that the guidance will have on the Company's consolidated financial statements. In January 2016, the FASB issued ASU No. 2016-01, "Financial Instruments - Overall: Recognition and Measurement of Financial Assets and Liabilities." This ASU addresses certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. This amendment supersedes the guidance to classify equity securities with readily determinable fair values into different categories, requires equity securities to be measured at fair value with changes in the fair value recognized through net income, and simplifies the impairment assessment of equity investments without readily determinable fair values. The amendment requires public business entities that are required to disclose the fair value of financial instruments measured at amortized cost on the balance sheet to measure that fair value using the exit price notion. The amendment requires an entity to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected to measure the liability at fair value in accordance with the fair value option. The amendment requires separate presentation of financial assets and financial liabilities by measurement category and form of financial asset on the balance sheet or in the accompanying notes to the financial statements. The amendment reduces diversity in current practice by clarifying that an entity should evaluate the need for a valuation allowance on a deferred tax asset related to available for sale securities in combination with the entity’s other deferred tax assets. This amendment is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Entities should apply the amendment by means of a cumulative-effect adjustment as of the beginning of the fiscal year of adoption, with the exception of the amendment related to equity securities without readily determinable fair values, which should be applied prospectively to equity investments that exist as of the date of adoption. The Company intends to adopt the accounting standard during the first quarter of 2018, as required, and is currently evaluating the impact that the guidance will have on the Company's consolidated financial statements. In September 2015, the FASB issued ASU No. 2015-16, "Business Combinations, Simplifying the Accounting for Measurement - Period Adjustments." The amendments in this update apply to all entities that have reported provisional amounts for items in a business combination for which the accounting is incomplete by the end of the reporting period in which the combination occurs and during the measurement period have an adjustment to provisional amounts recognized. In these cases, the acquirer must record, in the same period’s financial statements, the effect on earnings of changes in depreciation, amortization, or other income effects, if any, as a result of the change to the provisional amounts, calculated as if the accounting had been completed at the acquisition date. The amendments in this update are effective for fiscal years beginning after December 15, 2015 including interim periods within those fiscal years. The Company’s adoption of this ASU is not expected to have a material impact on its consolidated financial statements. In August 2014, the FASB issued ASU No. 2014-14, “Receivables - Troubled Debt Restructurings by Creditors: Classification of Certain Government-Guaranteed Mortgage Loans upon Foreclosure.” The amendments in this update affect creditors that hold government guaranteed mortgage loans, including those guaranteed by the Federal Housing Administration and the U.S. Department of Veterans Affairs. The amendments in this update require that a mortgage loan be derecognized and that a separate other receivable be recognized upon foreclosure if the following conditions are met: (i) the loan has a government guarantee that is not separable from the loan before foreclosure; (ii) at the time of foreclosure, the creditor has the intent to convey the real estate property to the guarantor and make a claim on the guarantee, and the creditor has the ability to recover under that claim; and (iii) at the time of foreclosure, any amount of the claim that is determined on the basis of the fair value of the real estate is fixed. Upon foreclosure, the separate other receivable should be measured based on the amount of the loan balance (principal and interest) expected to be recovered from the guarantor. The amendments in this update are effective for public business entities for annual periods, and interim periods within those annual periods, beginning after December 15, 2014. The Company's adoption of this ASU did not have a significant impact on its consolidated financial statements. In June 2014, the FASB issued ASU No. 2014-12, "Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period," which requires that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition. This update is effective for interim and annual periods beginning after December 15, 2015. The amendments can be applied prospectively to all awards granted or modified after the effective date or retrospectively to all awards with performance targets that are outstanding as of the beginning of the earliest annual period presented and to all new or modified awards thereafter. Early adoption is permitted. The Company does not expect that the adoption of this guidance will have a significant impact on the Company’s consolidated financial statements. Also in June 2014, the FASB issued ASU No. 2014-11, "Repurchase-to-Maturity Transactions, Repurchase Financings, and Disclosures" which aligns the accounting for repurchase to maturity transactions and repurchase agreements executed as a repurchase financing with the accounting for other typical repurchase agreements. Going forward, these transactions would all be accounted for as secured borrowings. This update is effective for the first interim or annual period beginning after December 15, 2014. In addition the disclosure of certain transactions accounted for as a sale is effective for the first interim or annual period beginning on or after December 15, 2014, and the disclosure for transactions accounted for as secured borrowings is required for annual periods beginning after December 15, 2014, and interim periods beginning after March 15, 2015. Early adoption was prohibited. The Company's adoption of this ASU did not have an impact on its consolidated financial statements.

Equity [Abstract]
Stockholders' Equity and Acquisition	Stockholders’ Equity and Acquisitions Stockholders’ Equity On January 15, 2003, the Bank completed its plan of conversion, and the Bank became a wholly owned subsidiary of the Company. The Company sold 59.6 million shares of common stock (par value $0.01 per share) at $10.00 per share. The Company received net proceeds in the amount of $567.2 million . In connection with the Bank’s commitment to its community, the plan of conversion provided for the establishment of a charitable foundation. Provident donated $4.8 million in cash and 1.92 million of authorized but unissued shares of common stock to the foundation, which amounted to $24.0 million in aggregate. The Company recognized an expense, net of income tax benefit, equal to the cash and fair value of the stock during 2003. Conversion costs were deferred and deducted from the proceeds of the shares sold in the offering. Upon completion of the plan of conversion, a “liquidation account” was established in an amount equal to the total equity of the Bank as of the latest practicable date prior to the conversion. The liquidation account was established to provide a limited priority claim to the assets of the Bank to “eligible account holders” and “supplemental eligible account holders” as defined in the Plan, who continue to maintain deposits in the Bank after the conversion. In the unlikely event of a complete liquidation of the Bank, and only in such event, each eligible account holder and supplemental eligible account holder would receive a liquidation distribution, prior to any payment to the holder of the Bank’s common stock. This distribution would be based upon each eligible account holder’s and supplemental eligible account holder’s proportionate share of the then total remaining qualifying deposits. At December 31, 2015 , the liquidation account, which is an off-balance sheet memorandum account, amounted to $13.9 million . Acquisitions On April 1, 2015, Beacon Trust Company ("Beacon"), a wholly owned subsidiary of The Provident Bank, completed its acquisition of certain assets and liabilities of The MDE Group, Inc. and the equity interests of Acertus Capital Management, LLC (together "MDE"), both Morristown, New Jersey-based registered investment advisory firms that manage assets for affluent and high net-worth clients. MDE was acquired with both cash and contingent consideration. The Company recognized goodwill of $18.3 million and a customer relationship intangible of $7.0 million related to the acquisition. The Company recognized a contingent consideration liability at its fair value of $338,000 . The contingent consideration arrangement requires the Company to pay additional cash consideration to MDE’s former stakeholders four years after the closing of the acquisition if certain revenue targets are met. The fair value of the contingent consideration was estimated using a discounted cash flow model. The acquisition agreement limits the total payment to a maximum of $12.5 million , to be determined based on actual future results. On October 31, 2014, Beacon acquired the fiduciary account relationships of Suffolk County National Bank, a subsidiary of Suffolk Bancorp, in Suffolk County, New York. On May 30, 2014, the Company completed its acquisition of Team Capital Bank ("Team Capital"), which after purchase accounting adjustments added $964.0 million to total assets, $631.2 million to loans, and $769.9 million to deposits. Total consideration paid for Team Capital was $115.1 million : $31.6 million in cash and 4.9 million shares of common stock valued at $83.5 million on the acquisition date. Team Capital was merged with and into the Company's subsidiary, The Provident Bank as of the close of business on the date of acquisition. The transaction was accounted for under the acquisition method of accounting. Under this method of accounting, the purchase price has been allocated to the respective assets acquired and liabilities assumed based upon their estimated fair values, net of tax. The excess of consideration paid over the fair value of the net assets acquired has been recorded as goodwill. The following table summarizes the estimated fair values of the assets acquired and the liabilities assumed at the date of acquisition from Team Capital, net of cash consideration paid (in thousands): At May 30, 2014 Assets acquired: Cash and cash equivalents, net $ 68,650 Securities available for sale 157,635 Loans 631,209 Bank-owned life insurance 22,319 Banking premises and equipment 24,778 Accrued interest receivable 3,060 Goodwill 40,897 Other intangibles assets 9,868 Foreclosed assets, net 653 Other assets 4,905 Total assets acquired 963,974 Liabilities assumed: Deposits 769,936 Borrowed Funds 112,835 Other liabilities (2,314 ) Total liabilities assumed 880,457 Net assets acquired $ 83,517 Upon the completion and filing of the Team Capital short-period tax return for the period ended May 30, 2014, a net operating loss carryback claim was filed with the Internal Revenue Service to reclaim taxes previously paid by Team Capital in the prior two years. As a result of the claim process, the Company determined that the tax receivable established by Team Capital at the May 30, 2014 acquisition date was overstated by $543,000 . In May 2015, the Company decreased the tax receivable recorded at the date of acquisition by $543,000 , along with a corresponding increase to goodwill. The purchase accounting for the Team Capital transaction is complete, and is reflected in both the table above and the Company's Consolidated Financial Statements. Fair Value Measurement of Assets Acquired and Liabilities Assumed The methods used to determine the fair value of the assets acquired and liabilities assumed in the Team Capital acquisition were as follows: Securities Available for Sale The estimated fair values of the investment securities classified as available for sale were calculated utilizing Level 1 and Level 2 inputs. Management reviewed the data and assumptions used by its third party provider in pricing the securities to ensure the highest level of significant inputs is derived from observable market data. These prices were validated against other pricing sources and broker-dealer indications. Loans The acquired loan portfolio was valued based on current guidance which defines fair value as the price that would be received to sell an asset or transfer a liability in an orderly transaction between market participants at the measurement date. Level 3 inputs were utilized to value the portfolio and included the use of present value techniques employing cash flow estimates and the incorporated assumptions that marketplace participants would use in estimating fair values. In instances where reliable market information was not available, the Company used its own assumptions in an effort to determine reasonable fair value. Specifically, Management utilized three separate fair value analyses which a market participant would employ in estimating the total fair value adjustment. The three separate fair valuation methodologies used were: 1) interest rate loan fair value analysis; 2) general credit fair value adjustment; and 3) specific credit fair value adjustment. To prepare the interest rate fair value analysis, loans were grouped by characteristics such as loan type, term, collateral and rate. Market rates for similar loans were obtained from various external data sources and reviewed by Company management for reasonableness. The average of these rates was used as the fair value interest rate a market participant would utilize. A present value approach was utilized to calculate the interest rate fair value adjustment. The general credit fair value adjustment was calculated using a two part general credit fair value analysis: 1) expected lifetime losses; and 2) estimated fair value adjustment for qualitative factors. The expected lifetime losses were calculated using an average of historical losses of the Company, the acquired bank and peer banks. The adjustment related to qualitative factors was impacted by general economic conditions and the risk related to lack of familiarity with the originator's underwriting process. To calculate the specific credit fair value adjustment, management reviewed the acquired loan portfolio for loans meeting the definition of an impaired loan with deteriorated credit quality. Loans meeting this definition were reviewed by comparing the contractual cash flows to expected collectible cash flows. The aggregate expected cash flows less the acquisition date fair value resulted in an accretable yield amount. The accretable yield amount will be recognized over the life of the loans on a level yield basis as an adjustment to yield. Deposits and Core Deposit Premium Core deposit premium represents the value assigned to demand, interest checking, money market and savings accounts acquired as part of an acquisition. The core deposit premium value represents the future economic benefit, including the present value of future tax benefits, of the potential cost savings from acquiring core deposits as part of an acquisition compared to the cost alternative funding sources and was valued utilizing Level 2 inputs. Time deposits are not considered to be core deposits as they are assumed to have a low expected average life upon acquisition. The fair value of time deposits represents the present value of the expected contractual payments discounted by market rates for similar time deposits and was valued utilizing Level 2 inputs. Borrowed Funds The fair value for borrowed funds was obtained from actual prepayment rates from the FHLB - Pittsburgh, a Level 2 input. These borrowings were redeemed after the acquisition date and the fair value adjustment was fully amortized in the quarter ended June 30, 2014.

Investments, Debt and Equity Securities [Abstract]
Investment Securities Held to Maturity	Investment Securities Held to Maturity Investment securities held to maturity at December 31, 2015 and 2014 are summarized as follows (in thousands): 2015 Amortized cost Gross unrealized gains Gross unrealized losses Fair value Agency obligations $ 4,096 9 (8 ) 4,097 Mortgage-backed securities 1,597 61 — 1,658 State and municipal obligations 458,062 15,094 (495 ) 472,661 Corporate obligations 9,929 11 (25 ) 9,915 $ 473,684 15,175 (528 ) 488,331 2014 Amortized cost Gross unrealized gains Gross unrealized losses Fair value Agency obligations $ 6,813 17 (20 ) 6,810 Mortgage-backed securities 2,816 123 — 2,939 State and municipal obligations 449,410 13,814 (986 ) 462,238 Corporate obligations 10,489 29 (32 ) 10,486 $ 469,528 13,983 (1,038 ) 482,473 The Company generally purchases securities for long-term investment purposes, and differences between carrying and fair values may fluctuate during the investment period. Investment securities held to maturity having a carrying value of $378,538,000 and $343,127,000 at December 31, 2015 and 2014 , respectively, were pledged to secure other borrowings, securities sold under repurchase agreements and government deposits. The amortized cost and fair value of investment securities held to maturity at December 31, 2015 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. 2015 Amortized cost Fair value Due in one year or less $ 9,081 9,151 Due after one year through five years 52,625 53,554 Due after five years through ten years 218,488 227,203 Due after ten years 191,893 196,765 $ 472,087 486,673 Mortgage-backed securities totaling $1.6 million at amortized cost and $1.7 million at fair value are excluded from the table above as their expected lives are expected to be shorter than the contractual maturity date due to principal prepayments. During 2015 , the Company recognized gains of $8,000 and no losses related to calls on certain securities in the held to maturity portfolio, with total proceeds from the calls totaling $26,973,000 . There were no sales of securities from the held to maturity portfolio for the year ended December 31, 2015 . In 2014 , the Company recognized gains of $23,000 and no losses related to calls on certain securities in the held to maturity portfolio, with total proceeds from the calls totaling $15,156,000 . In addition, for the year ended December 31, 2014 , the Company recognized a gross loss of $3,000 , and no gross gains, related to the sales of certain securities, with the proceeds totaling $524,000 . The sales of these securities were in response to the credit deterioration of the issuers. The following table represents the Company’s disclosure on investment securities held to maturity with temporary impairment (in thousands): December 31, 2015 Unrealized Losses Less than 12 months 12 months or longer Total Fair value Gross unrealized losses Fair value Gross unrealized losses Fair value Gross unrealized losses Agency obligations $ 1,244 (6 ) 278 (2 ) 1,522 (8 ) State and municipal obligations 24,266 (165 ) 17,746 (330 ) 42,012 (495 ) Corporate obligations 5,840 (18 ) 744 (7 ) 6,584 (25 ) $ 31,350 (189 ) 18,768 (339 ) 50,118 (528 ) December 31, 2014 Unrealized Losses Less than 12 months 12 months or longer Total Fair value Gross unrealized losses Fair value Gross unrealized losses Fair value Gross unrealized losses Agency obligations $ 3,735 (20 ) — — 3,735 (20 ) State and municipal obligations 27,679 (217 ) 47,079 (769 ) 74,758 (986 ) Corporate obligations 6,888 (32 ) — — 6,888 (32 ) $ 38,302 (269 ) 47,079 (769 ) 85,381 (1,038 ) Based on its detailed review of the securities portfolio, the Company believes that as of December 31, 2015 , securities with unrealized loss positions shown above do not represent impairments that are other-than-temporary. The review of the portfolio for other-than-temporary impairment considered the percentage and length of time the fair value of an investment is below book value as well as general market conditions, changes in interest rates, credit risk, whether the Company has the intent to sell the securities and whether it is not more likely than not that the Company would be required to sell the securities before the anticipated recovery. The number of securities in an unrealized loss position as of December 31, 2015 totaled 99 , compared with 163 at December 31, 2014 . All temporarily impaired investment securities were investment grade at December 31, 2015 .

Investments, Debt and Equity Securities [Abstract]
Securities Available for Sale	Securities Available for Sale Securities available for sale at December 31, 2015 and 2014 are summarized as follows (in thousands): 2015 Amortized cost Gross unrealized gains Gross unrealized losses Fair value U.S. Treasury obligations $ 8,006 — (2 ) 8,004 Agency obligations 82,396 82 (148 ) 82,330 Mortgage-backed securities 857,430 9,828 (3,397 ) 863,861 State and municipal obligations 4,193 115 — 4,308 Corporate obligations 5,516 6 (10 ) 5,512 Equity securities 397 122 — 519 $ 957,938 10,153 (3,557 ) 964,534 2014 Amortized cost Gross unrealized gains Gross unrealized losses Fair value U.S. Treasury obligations $ 8,016 3 (3 ) 8,016 Agency obligations 94,871 268 (63 ) 95,076 Mortgage-backed securities 944,796 15,610 (3,149 ) 957,257 State and municipal obligations 6,855 147 — 7,002 Corporate obligations 6,526 9 (15 ) 6,520 Equity securities 397 127 — 524 $ 1,061,461 16,164 (3,230 ) 1,074,395 Securities available for sale having a carrying value of $614,824,000 and $585,928,000 at December 31, 2015 and 2014 , respectively, are pledged to secure other borrowings and securities sold under repurchase agreements. The amortized cost and fair value of securities available for sale at December 31, 2015 , 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. 2015 Amortized cost Fair value Due in one year or less $ 27,044 27,058 Due after one year through five years 67,106 67,037 Due after five years through ten years 3,681 3,701 Due after ten years 2,280 2,358 $ 100,111 100,154 Mortgage-backed securities totaling $857.4 million at amortized cost and $863.9 million at fair value are excluded from the table above as their expected lives are expected to be shorter than the contractual maturity date due to principal prepayments. Also excluded from the table above are equity securities of $ 397,000 at amortized cost and $ 519,000 at fair value. During 2015 , proceeds from the sale of securities available for sale were $14,005,000 , resulting in gross gains of $643,000 and no gross losses. Also, for the year ended December 31, 2015 , proceeds from calls on securities available for sale totaled $1,110,000 , with gross gains of $3,000 and no gross losses recognized. For the 2014 period, proceeds from the sale of securities available for sale were $24,509,000 resulting in gross gains of $632,000 and gross losses of 404,000 losses. Also, for the year ended December 31, 2014 , proceeds from calls on securities available for sale totaled $740,000 , with gross gains of $2,000 and no gross losses recognized. The Company estimates the loss projections for each non-agency mortgage-backed security by stressing the individual loans collateralizing the security and applying a range of expected default rates, loss severities, and prepayment speeds in conjunction with the underlying credit enhancement for each security. Based on specific assumptions about collateral and vintage, a range of possible cash flows was identified to determine whether other-than-temporary impairment existed during the year ended December 31, 2015 . The following table presents a roll-forward of the credit loss component of other-than-temporary impairment (“OTTI”) on debt securities for which a non-credit component of OTTI was recognized in other comprehensive income. OTTI recognized in earnings after that date for credit-impaired debt securities is presented as an addition in two components, based upon whether the current period is the first time a debt security was credit-impaired (initial credit impairment) or is not the first time a debt security was credit impaired (subsequent credit impairment). Changes in the credit loss component of credit-impaired debt securities were as follows (in thousands): December 31, 2015 2014 2013 Beginning credit loss amount $ — 1,674 1,240 Add: Initial OTTI credit losses — — — Subsequent OTTI credit losses — — 434 Less: Realized losses for securities sold — 1,674 — Securities intended or required to be sold — — — Increases in expected cash flows on debt securities — — — Ending credit loss amount $ — — 1,674 For the years ended December 31, 2015 and 2014 , the Company did not incur a net other-than-temporary impairment charge on securities available for sale. In 2014 , the Company realized a $59,000 gain and a $365,000 loss on the sale of previously impaired non-Agency mortgage-backed securities, respectively. The Company previously incurred cumulative credit losses of $1.7 million on these securities. Prior to these charges, any impairment was considered temporary and was recorded as an unrealized loss on securities available for sale and reflected as a reduction of equity, net of tax, through accumulated other comprehensive income. The following table represents the Company’s disclosure on securities available for sale with temporary impairment (in thousands): December 31, 2015 Unrealized Losses Less than 12 months 12 months or longer Total Fair value Gross unrealized losses Fair value Gross unrealized losses Fair value Gross unrealized losses U.S. Treasury obligations $ 8,004 (2 ) — — 8,004 (2 ) Agency obligations 59,197 (148 ) — — 59,197 (148 ) Mortgage-backed securities 327,263 (2,427 ) 47,911 (970 ) 375,174 (3,397 ) Corporate obligations 500 — 992 (10 ) 1,492 (10 ) $ 394,964 (2,577 ) 48,903 (980 ) 443,867 (3,557 ) December 31, 2014 Unrealized Losses Less than 12 months 12 months or longer Total Fair value Gross unrealized losses Fair value Gross unrealized losses Fair value Gross unrealized losses U.S Treasury obligations $ 5,937 (3 ) — — 5,937 (3 ) Agency obligations 24,404 (40 ) 5,010 (23 ) 29,414 (63 ) Mortgage-backed securities 55,488 (221 ) 206,669 (2,928 ) 262,157 (3,149 ) Corporate obligations 3,466 (15 ) — — 3,466 (15 ) $ 89,295 (279 ) 211,679 (2,951 ) 300,974 (3,230 ) The temporary loss position associated with debt securities is the result of changes in interest rates relative to the coupon of the individual security and changes in credit spreads. In addition, there remains a lack of liquidity in certain sectors of the mortgage-backed securities market. Increases in delinquencies and foreclosures have resulted in limited trading activity and significant price declines, regardless of favorable movements in interest rates. The Company does not have the intent to sell securities in a temporary loss position at December 31, 2015 , nor is it more likely than not that the Company will be required to sell the securities before the anticipated recovery. The number of securities in an unrealized loss position as of December 31, 2015 totaled 64 , compared with 43 at December 31, 2014 . There were three private label mortgage-backed securities in an unrealized loss position at December 31, 2015 , with an amortized cost of $773,000 and unrealized losses totaling $5,000 . All three private label mortgage-backed securities were investment grade at December 31, 2015 .

Loans Receivable and Allowance for Loan Losses	Loans Receivable and Allowance for Loan Losses Loans receivable at December 31, 2015 and 2014 are summarized as follows (in thousands): 2015 2014 Mortgage loans: Residential $ 1,254,036 1,251,445 Commercial 1,714,923 1,694,359 Multi-family 1,233,792 1,041,582 Construction 331,649 221,102 Total mortgage loans 4,534,400 4,208,488 Commercial loans 1,433,447 1,262,422 Consumer loans 566,175 611,467 Total gross loans 6,534,022 6,082,377 Purchased credit-impaired ("PCI") loans 3,435 4,510 Premiums on purchased loans 5,740 5,307 Unearned discounts (41 ) (53 ) Net deferred fees (5,482 ) (6,636 ) $ 6,537,674 6,085,505 Premiums and discounts on purchased loans are amortized over the lives of the loans as an adjustment to yield. Required reductions due to loan prepayments are charged against interest income. For the years ended December 31, 2015 , 2014 and 2013 , $ $1,100,000 , $694,000 and $1,286,000 , respectively, decreased interest income as a result of prepayments and normal amortization. The following table summarizes the aging of loans receivable by portfolio segment and class of loans, excluding PCI loans (in thousands): At December 31, 2015 30-59 Days 60-89 Days Non-accrual 90 days or more past due and accruing Total Past Due Current Total Loans Receivable Mortgage loans: .

The principal amount of these nonaccrual loans was $44.4 million and $53.9 million at December 31, 2015 and 2014 , respectively. At December 31, 2015 , there was one commercial loan for $ 165,000 which was ninety days or greater past due and still accruing interest. This loan was past maturity and well secured at December 31, 2015, which subsequent to the end of the year was refinanced by the Company. There were no loans ninety days or greater past due and still accruing interest in 2014 . If the non-accrual loans had performed in accordance with their original terms, interest income would have increased by $1,200,000 , $1,877,000 and $1,913,000 , for the years ended December 31, 2015 , 2014 and 2013 , respectively. The amount of cash basis interest income that was recognized on impaired loans during the years ended December 31, 2015 , 2014 and 2013 was not material for the periods presented. The Company defines an impaired loan as a non-homogenous loan greater than $1.0 million 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 also include all loans modified as troubled debt restructurings (“TDRs”). A loan is deemed to be a TDR when a loan modification resulting in a concession is made by the Bank in an effort to mitigate potential loss arising from a borrower’s financial difficulty. Smaller balance homogeneous loans including residential mortgages and other consumer loans are evaluated collectively for impairment and are excluded from the definition of impaired loans, unless modified as TDRs. The Company separately calculates the reserve for loan loss on impaired loans. The Company may recognize impairment of a loan based upon: (1) the present value of expected cash flows discounted at the effective interest rate; or (2) if a loan is collateral dependent, the fair value of collateral; or (3) the market price of the loan. Additionally, if impaired loans have risk characteristics in common, those loans may be aggregated and historical statistics may be used as a means of measuring those impaired loans. The Company uses third-party appraisals to determine the fair value of the underlying collateral in its analysis of collateral dependent impaired loans. A third-party appraisal is generally ordered as soon as a loan is designated as a collateral dependent impaired loan and updated annually, or more frequently if required. A specific allocation of the allowance for loan losses is established for each impaired loan with a carrying balance greater than the collateral’s fair value, less estimated costs to sell. Charge-offs are generally taken for the amount of the specific allocation when operations associated with the respective property cease and it is determined that collection of amounts due will be derived primarily from the disposition of the collateral. At each fiscal quarter end, if a loan is designated as a collateral dependent impaired loan 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. The Company believes there have been no significant time lapses as a result of this process. At December 31, 2015 , there were 148 impaired loans totaling $50.9 million , of which 143 loans totaling $43.9 million were TDRs. Included in this total were 122 TDRs related to 120 borrowers totaling $26.0 million that were performing in accordance with their restructured terms and which continued to accrue interest at December 31, 2015 . At December 31, 2014 , there were 147 impaired loans totaling $85.4 million , of which 143 loans totaling $81.7 million were TDRs. Included in this total were 123 TDRs related to 120 borrowers totaling $54.8 million that were performing in accordance with their restructured terms and which continued to accrue interest at December 31, 2014 . Loans receivable summarized by portfolio segment and impairment method, excluding PCI loans are as follows (in thousands): At December 31, 2015 Mortgage loans Commercial loans Consumer loans Total Portfolio Segments Individually evaluated for impairment $ 26,743 21,756 2,368 50,867 Collectively evaluated for impairment 4,507,657 1,411,691 563,807 6,483,155 Total gross loans $ 4,534,400 1,433,447 566,175 6,534,022 At December 31, 2014 Mortgage loans Commercial loans Consumer loans Total Portfolio Segments Individually evaluated for impairment $ 66,548 16,463 2,384 85,395 Collectively evaluated for impairment 4,141,940 1,245,959 609,083 5,996,982 Total gross loans $ 4,208,488 1,262,422 611,467 6,082,377 The allowance for loan losses is summarized by portfolio segment and impairment classification, excluding PCI loans as follows (in thousands): At December 31, 2015 Mortgage loans Commercial loans Consumer loans Total Portfolio Segments Unallocated (1) Total Individually evaluated for impairment $ 2,086 91 94 2,271 — 2,271 Collectively evaluated for impairment 30,008 25,738 3,407 59,153 — 59,153 Total $ 32,094 25,829 3,501 61,424 — 61,424 (1) For the year ended December 31, 2015, the Company enhanced its allowance for loan losses process and allocated the previously unallocated allowance using both qualitative and quantitative factors. At December 31, 2014 Mortgage loans Commercial loans Consumer loans Total Portfolio Segments Unallocated Total Individually evaluated for impairment $ 4,696 2,318 113 7,127 — 7,127 Collectively evaluated for impairment 27,281 22,063 4,768 54,112 495 54,607 Total $ 31,977 24,381 4,881 61,239 495 61,734 Loan modifications to customers experiencing financial difficulties that are considered TDRs primarily involve lowering the monthly payments on such loans through either a reduction in interest rate below a market rate, an extension of the term of the loan without a corresponding adjustment to the risk premium reflected in the interest rate, or a combination of these two methods. These modifications generally do not result in the forgiveness of principal or accrued interest. In addition, the Company 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 tables present the number of loans modified as TDRs during the years ended December 31, 2015 and 2014 and their balances immediately prior to the modification date and post-modification as of December 31, 2015 and 2014 .

Estimated collateral values of collateral dependent impaired loans modified during the years ended December 31, 2015 and 2014 exceeded the carrying amounts of such loans. As a result, there were $465,000 of charge-offs recorded on collateral dependent impaired loans for the year ended December 31, 2015 . There were no charge-offs recorded on collateral dependent impaired loans for the year ended December 31, 2014 . The allowance for loan losses associated with the TDRs presented in the preceding tables totaled $99,000 and $419,000 at December 31, 2015 and 2014 , respectively and were included in the allowance for loan losses for loans individually evaluated for impairment. The TDRs presented in the preceding tables had a weighted average modified interest rate of approximately 5.25% and 4.58% , compared to a yield of 5.71% and 5.69% prior to modification for the years ended December 31, 2015 and 2014 , respectively. The following table presents loans modified as TDRs within the previous 12 months from December 31, 2015 and 2014 , and for which there was a payment default (90 days or more past due) during the years ended December 31, 2015 and 2014 : Year Ended December 31, 2015 Year Ended December 31, 2014 Troubled Debt Restructurings Subsequently Defaulted Number of Loans Outstanding Recorded Investment Number of Loans Outstanding Recorded Investment ($ in thousands) ($ in thousands) Mortgage loans: Construction 1 $ 2,351 — $ — Total mortgage loans 1 2,351 — — Commercial loans 4 6,822 — — Total restructured loans 5 $ 9,173 — $ — TDRs that subsequently default are considered collateral dependent impaired loans and are evaluated for impairment based on the estimated fair value of the underlying collateral less expected selling costs. PCI loans are loans acquired at a discount primarily due to deteriorated credit quality. As part of the Team Capital acquisition, $5.2 million of the loans purchased at May 30, 2014 were determined to be PCI loans. PCI loans are accounted for at fair value, based upon the present value of expected future cash flows, with no related allowance for loan losses. The following table presents information regarding the estimates of the contractually required payments, the cash flows expected to be collected and the estimated fair value of the PCI loans acquired from Team Capital at May 30, 2014 (in thousands): May 30, 2014 Contractually required principal and interest $ 12,505 Contractual cash flows not expected to be collected (non-accretable discount) (6,475 ) Expected cash flows to be collected at acquisition 6,030 Interest component of expected cash flows (accretable yield) (810 ) Fair value of acquired loans $ 5,220 PCI loans totaled $3.4 million at December 31, 2015 , compared to $4.5 million at December 31, 2014 and $5.2 million at acquisition from Team Capital on May 30, 2014. The $1.1 million and $1.8 million decrease from December 31, 2014 and the May 31, 2014 acquisition date was largely due to the full repayment and greater than projected cash flows on certain PCI loans. This resulted in a $230,000 and a $348,000 increase in interest income for the years ended December 31, 2015 and 2014, respectively, due to the acceleration of accretable and non-accretable discount on these loans. The following table summarizes the changes in the accretable yield for PCI loans for the years ended December 31, 2015 and 2014 (in thousands): Year ended December 31, 2015 2014 Beginning balance $ 695 $ — Acquisition — 810 Accretion (810 ) (592 ) Reclassification from non-accretable difference 791 477 Ending balance $ 676 $ 695 The activity in the allowance for loan losses for the years ended December 31, 2015 , 2014 and 2013 is as follows (in thousands): Years Ended December 31, 2015 2014 2013 Balance at beginning of period $ 61,734 64,664 70,348 Provision charged to operations 4,350 4,650 5,500 Recoveries of loans previously charged off 4,168 3,292 3,222 Loans charged off (8,828 ) (10,872 ) (14,406 ) Balance at end of period $ 61,424 61,734 64,664 The activity in the allowance for loan losses by portfolio segment for the years ended December 31, 2015 and 2014 are as follows (in thousands): For the Year Ended December 31, 2015 Mortgage loans Commercial loans Consumer loans Total Portfolio Segments Unallocated Total Balance at beginning of period $ 31,977 24,381 4,881 61,239 495 61,734 Provision charged to operations 2,357 1,898 590 4,845 (495 ) 4,350 Recoveries of loans previously charged off 247 2,413 1,508 4,168 — 4,168 Loans charged off (2,487 ) (2,863 ) (3,478 ) (8,828 ) — (8,828 ) Balance at end of period $ 32,094 25,829 3,501 61,424 — 61,424 For the Year ended December 31, 2014 Mortgage loans Commercial loans Consumer loans Total Portfolio Segments Unallocated Total Balance at beginning of period $ 34,144 24,107 4,929 63,180 1,484 64,664 Provision charged to operations 1,455 2,947 1,237 5,639 (989 ) 4,650 Recoveries of loans previously charged off 286 1,776 1,230 3,292 — 3,292 Loans charged off (3,908 ) (4,449 ) (2,515 ) (10,872 ) — (10,872 ) Balance at end of period $ 31,977 24,381 4,881 61,239 495 61,734 Impaired loans receivable by class, excluding PCI loans are summarized as follows (in thousands): At December 31, 2015 At December 31, 2014 Unpaid Principal Balance Recorded Investment Related Allowance Average Recorded Investment Interest Income Recognized Unpaid Principal Balance Recorded Investment Related Allowance Average Recorded Investment Interest Income Recognized Loans with no related allowance Mortgage loans: Residential $ 12,144 8,799 — 9,079 451 $ 14,942 10,629 — 11,138 357 Commercial — — — — — 4,971 4,708 — 4,713 — Multi-family — — — — — — — — — — Construction 2,358 2,351 — 1,170 16 — — — — — Total 14,502 11,150 — 10,249 467 19,913 15,337 — 15,851 357 Commercial loans 23,754 21,144 — 21,875 747 2,718 2,179 — 1,823 4 Consumer loans 1,560 1,082 — 1,121 48 1,250 830 — 870 28 Total loans $ 39,816 33,376 — 33,245 1,262 $ 23,881 18,346 — 18,544 389 Loans with an allow-ance recorded Mortgage loans: Residential $ 14,997 14,353 1,901 14,500 505 $ 15,523 14,906 2,367 15,106 555 Commercial 1,240 1,240 185 1,361 63 37,555 36,306 2,329 36,674 914 Multi-family — — — — — — — — — — Construction — — — — — — — — — — Total 16,237 15,593 2,086 15,861 568 53,078 51,212 4,696 51,780 1,469 Commercial loans 612 612 91 807 52 15,990 14,283 2,318 15,967 390 Consumer loans 1,297 1,286 94 1,312 67 1,565 1,554 113 1,578 80 Total loans $ 18,146 17,491 2,271 17,980 687 $ 70,633 67,049 7,127 69,325 1,939 Total Mortgage loans: Residential $ 27,141 23,152 1,901 23,579 956 $ 30,465 25,535 2,367 26,244 912 Commercial 1,240 1,240 185 1,361 63 42,526 41,014 2,329 41,387 914 Multi-family — — — — — — — — — — Construction 2,358 2,351 — 1,170 16 — — — — — Total 30,739 26,743 2,086 26,110 1,035 72,991 66,549 4,696 67,631 1,826 Commercial loans 24,366 21,756 91 22,682 799 18,708 16,462 2,318 17,790 394 Consumer loans 2,857 2,368 94 2,433 115 2,815 2,384 113 2,448 108 Total loans $ 57,962 50,867 2,271 51,225 1,949 $ 94,514 85,395 7,127 87,869 2,328 At December 31, 2015 , impaired loans consisted of 148 residential, commercial and commercial mortgage loans totaling $50,867,000 , of which 26 loans totaling $24,894,000 were included in nonaccrual loans. At December 31, 2014 , impaired loans consisted of 147 residential, commercial and commercial mortgage loans totaling $85,395,000 , of which 24 loans totaling $30,619,000 were included in nonaccrual loans. Specific allocations of the allowance for loan losses attributable to impaired loans totaled $2,271,000 and $7,127,000 at December 31, 2015 and 2014 , respectively. At December 31, 2015 and 2014 , impaired loans for which there was no related allowance for loan losses totaled $33,376,000 and $18,346,000 , respectively. The average balances of impaired loans during the years ended December 31, 2015 and 2014 were $51,225,000 and $87,869,000 , respectively. In the normal course of conducting its business, the Bank extends credit to meet the financing needs of its customers through commitments. Commitments and contingent liabilities, such as commitments to extend credit (including loan commitments of $866,403,000 and $908,581,000 , at December 31, 2015 and 2014 , respectively, and undisbursed home equity and personal credit lines of $287,942,000 and $300,029,000 , at December 31, 2015 and 2014 , respectively) exist, which are not reflected in the accompanying consolidated financial statements. These instruments involve elements of credit and interest rate risk in excess of the amount recognized in the consolidated financial statements. The Bank uses the same credit policies and collateral requirements in making commitments and conditional obligations as it does for on-balance sheet loans. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since the commitments may expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. The Bank evaluates each customer’s creditworthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary by the Bank upon extension of credit, is based on management’s credit evaluation of the borrower. The Bank grants residential real estate loans on single- and multi-family dwellings to borrowers primarily in New Jersey. Its borrowers’ abilities to repay their obligations are dependent upon various factors, including the borrowers’ income and net worth, cash flows generated by the underlying collateral, value of the underlying collateral, and priority of the Bank’s lien on the property. Such factors are dependent upon various economic conditions and individual circumstances beyond the Bank’s control; the Bank is therefore subject to risk of loss. The Bank believes that its lending policies and procedures adequately minimize the potential exposure to such risks and that adequate provisions for loan losses are provided for all known and inherent risks. Collateral and/or guarantees are required for virtually all loans. The Company 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 his or her portfolio. These risk ratings are then reviewed by the department manager and/or the Chief Lending Officer and by the Credit Administration Department. The risk ratings are also confirmed through periodic loan review examinations, which are currently performed by an independent third party. Reports by the independent third party are presented directly to the Audit Committee of the Board of Directors.

Compensation and Retirement Disclosure [Abstract]
Benefit Plans	Benefit Plans Pension and Post-retirement Benefits 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 pension 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. Based on the measurement date of December 31, 2015 , no contributions will be made to the pension plan in 2016 . In an effort to lower and reduce the volatility of its future pension costs, the Company offered a lump sum pension distribution option to its terminated vested employees in the quarter ended June 30, 2014. For the year ended December 31, 2014, the Plan paid $4.3 million to those employees that elected to receive lump sum pension distributions and the Company realized an associated charge of $1.3 million . This charge was a pro rata share of the unrecognized losses recorded in other comprehensive income. In addition to pension benefits, certain healthcare 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 to new entrants and retiree life insurance benefits were eliminated for employees with less than ten years of service as of December 31, 2006. The following table sets forth information regarding the pension plan and post-retirement healthcare and life insurance plans (in thousands): Pension Post-retirement 2015 2014 2013 2015 2014 2013 Change in benefit obligation: Benefit obligation at beginning of year $ 28,921 28,605 32,189 28,333 22,086 25,116 Service cost — — — 168 169 240 Interest cost 1,137 1,271 1,273 1,122 1,087 981 Actuarial loss (gain) 78 51 114 122 51 (210 ) Benefits paid (1,179 ) (5,326 ) (969 ) (644 ) (670 ) (624 ) Change in actuarial assumptions (683 ) 4,320 (4,002 ) (3,407 ) 5,610 (3,417 ) Benefit obligation at end of year $ 28,274 28,921 28,605 25,694 28,333 22,086 Change in plan assets: Fair value of plan assets at beginning of year $ 42,744 45,202 40,072 — — — Actual return on plan assets (117 ) 2,868 6,099 — — — Employer contributions — — — 644 670 624 Benefits paid (1,179 ) (5,326 ) (969 ) (644 ) (670 ) (624 ) Fair value of plan assets at end of year $ 41,448 42,744 45,202 — — — Funded status at end of year $ 13,174 13,823 16,597 (25,694 ) (28,333 ) (22,086 ) For the years ended December 31, 2015 and 2014, the Company, in the measurement of its pension plan and post-retirement obligations updated its mortality assumptions to the RP 2014 mortality table with the fully generational projection scale MP 2015 and MP 2014 issued by The Society of Actuaries ("SOA") in October 2015 and 2014, respectively. For the year ended December 31, 2014, the introduction of the updated mortality data resulted in an actuarial loss of $1.5 million and $3.0 million for the pension and post-retirement plans, respectively, and was reflected in other comprehensive income. The prepaid pension benefits of $ 13.2 million and the unfunded post-retirement healthcare and life insurance benefits of $ 25.7 million at December 31, 2015 are included in other assets and other liabilities, respectively, in the consolidated statement of financial condition. The components of accumulated other comprehensive loss (gain) related to the pension plan and other post-retirement benefits, on a pre-tax basis, at December 31, 2015 and 2014 are summarized in the following table (in thousands): Pension Post-retirement 2015 2014 2015 2014 Unrecognized prior service cost $ — — — (1 ) Unrecognized net actuarial loss (gain) 12,155 10,887 (1,498 ) 1,788 Total accumulated other comprehensive loss (gain) $ 12,155 10,887 (1,498 ) 1,787 Net periodic benefit cost (increase) for the years ending December 31, 2015 , 2014 and 2013 , included the following components (in thousands): Pension Post-retirement 2015 2014 2013 2015 2014 2013 Service cost $ — — — 168 169 240 Interest cost 1,137 1,271 1,273 1,122 1,087 981 Return on plan assets (2,530 ) (3,463 ) (3,167 ) — — — Amortization of: Net gain (loss) 774 441 1,352 1 (204 ) 15 Lump sum pension distribution — 1,336 — — — — Unrecognized prior service cost — — — (1 ) (4 ) (4 ) Net periodic benefit (increase) cost $ (619 ) (415 ) (542 ) 1,290 1,048 1,232 The weighted average actuarial assumptions used in the plan determinations at December 31, 2015 , 2014 and 2013 were as follows: Pension Post-retirement 2015 2014 2013 2015 2014 2013 Discount rate 4.50 % 4.00 % 5.00 % 4.50 % 4.00 % 5.00 % Rate of compensation increase — — — — — — Expected return on plan assets 6.00 8.00 8.00 — — — Medical and life insurance benefits cost rate of increase — — — 6.00 6.00 6.00 The Company provides its actuary with certain rate assumptions used in measuring the benefit obligation. The most significant of these is the discount rate used to calculate the period-end present value of the benefit obligations, and the expense to be included in the following year’s financial statements. A lower discount rate will result in a higher benefit obligation and expense, while a higher discount rate will result in a lower benefit obligation and expense. The discount rate assumption was determined based on a cash flow-yield curve model specific to the Company’s pension and post-retirement plans. The Company compares this rate to certain market indices, such as long-term treasury bonds, or the Citigroup pension liability indices, for reasonableness. A discount rate of 4.50% was selected for the December 31, 2015 measurement date. Assumed health care cost trend rates have a significant effect on the amounts reported for health care plans. A 1% change in the assumed health care cost trend rate would have had the following effects on post-retirement benefits at December 31, 2015 (in thousands): 1% increase 1% decrease Effect on total service cost and interest cost $ 270 (210 ) Effect on post-retirement benefits obligation $ 4,460 (3,560 ) Estimated future benefit payments, which reflect expected future service, as appropriate for the next five years, are as follows (in thousands): Pension Post-retirement 2016 $ 1,090,000 $ 810,000 2017 1,137,000 843,000 2018 1,164,000 883,000 2019 1,189,000 924,000 2020 1,247,000 949,000 The weighted-average asset allocation of pension plan assets at December 31, 2015 and 2014 were as follows: Asset Category 2015 2014 Domestic equities 36 % 41 % Foreign equities 11 % 12 % Fixed income 51 % 45 % Real estate 2 % 2 % Cash 0 % 0 % Total 100 % 100 % The Company’s expected return on pension plan assets assumption is based on historical investment return experience and evaluation of input from the Investment Consultant and the Company's Benefits Committee which manages the pension plan’s assets. The expected return on pension plan assets is also impacted by the target allocation of assets, which is based on the Company’s goal of earning the highest rate of return while maintaining risk at acceptable levels. Management strives to have pension plan assets sufficiently diversified so that adverse or unexpected results from one security class will not have a significant detrimental impact on the entire portfolio. The target allocation of assets and acceptable ranges around the targets are as follows: Asset Category Target Allowable Range Domestic equities 44 % 35-55% Foreign equities 14 % 5-25% Fixed income 40 % 30-50% Real estate 2 % 0-10% Cash 0 % 0-35% Total 100 % The following tables present the assets that are measured at fair value on a recurring basis by level within the U.S. GAAP fair value hierarchy as reported on the statements of net assets available for Plan benefits at December 31, 2015 and 2014 , respectively. Financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement.

For 2015 , 2014 and 2013 , the Bank matched 25% of the first 6% contributed by the participants. The contribution percentage is determined by the Board of Directors in its sole discretion. The Bank’s aggregate contributions to the 401(k) Plan for 2015 , 2014 and 2013 were $770,000 , $674,000 and $587,000 , respectively. Supplemental Executive Retirement Plan The Bank maintains a non-qualified supplemental retirement plan for certain senior officers of the Bank. This plan was frozen as of April 1, 2003. The Supplemental Executive Retirement Plan, which is unfunded, provides benefits in excess of the benefits permitted to be paid by the pension plan under provisions of the tax law. Amounts expensed under this supplemental retirement plan amounted to $93,000 , $102,000 and $162,000 for the years 2015 , 2014 and 2013 , respectively. At December 31, 2015 , and 2014 , $2,110,000 and $2,166,000 , respectively, were recorded in other liabilities on the consolidated statements of condition for this supplemental retirement plan. A decrease of $82,000 , a decrease of $198,000 , and an increase of $56,000 , net of tax, were recorded in other comprehensive income for 2015 , 2014 and 2013 , respectively, in connection with this supplemental retirement plan. Retirement Plan for the Board of Directors of The Provident Bank The Bank maintains a Retirement Plan for the Board of Directors of the Bank, a non-qualified plan that provides cash payments for up to 10 years to eligible retired board members based on age and length of service requirements. The maximum payment under this plan to a board member, who terminates service on or after the age of 72 with at least ten years of service on the board, is forty quarterly payments of $1,250 . The Bank may suspend payments under this plan if it does not meet Federal Deposit Insurance Corporation or New Jersey Department of Banking and Insurance minimum capital requirements. The Bank may terminate this plan at any time although such termination may not reduce or eliminate any benefit previously accrued to a board member without his or her consent. The plan was amended in December 2005 to terminate benefits under this plan for any directors who had less than ten years of service on the board of directors of the Bank as of December 31, 2006. The plan further provides that, in the event of a change in control (as defined in the plan), the undistributed balance of a director’s accrued benefit will be distributed to him or her within 60 days of the change in control. The Bank paid $15,000 to former board members under this plan for each of the years ended December 31, 2015 , 2014 and 2013 . At December 31, 2015 and 2014 , $158,000 and $169,000 , respectively, were recorded in other liabilities on the consolidated statements of financial condition for this retirement plan. An increase of $1,800 , a decrease of $7,400 , and an increase of $6,000 , net of tax, were recorded in other comprehensive income for 2015 , 2014 and 2013 , respectively, in connection with this plan. Employee Stock Ownership Plan The ESOP is a tax-qualified plan designed to invest primarily in the Company’s common stock that provides employees with the opportunity to receive a funded retirement benefit from the Bank, based primarily on the value of the Company’s common stock. The ESOP purchased 4,769,464 shares of the Company’s common stock at an average price of $17.09 per share with the proceeds of a loan from the Company to the ESOP. The outstanding loan principal at December 31, 2015 , was $49.9 million . Shares of the Company’s common stock pledged as collateral for the loan are released from the pledge for allocation to participants as loan payments are made. For the ESOP years ending December 31, 2015 and 2014 , 209,631 shares and 201,512 shares were released, respectively. Unallocated ESOP shares held in suspense totaled 2,442,414 at December 31, 2015 , and had a fair value of $49.2 million . ESOP compensation expense for the years ended December 31, 2015 , 2014 and 2013 was $2,997,000 , $2,654,000 and $2,559,000 , respectively. Non-Qualified Supplemental Defined Contribution Plan (“the Supplemental Employee Stock Ownership Plan”) Effective January 1, 2004, the Bank established a deferred compensation plan for executive management and key employees of the Bank, known as The Provident Bank Non-Qualified Supplemental Employee Stock Ownership Plan (the “Supplemental ESOP”). The Supplemental ESOP was amended and restated as the Non-Qualified Supplemental Defined Contribution Plan (the “Supplemental DC Plan”), effective January 1, 2010. The Supplemental DC Plan is a non-qualified plan that provides additional benefits to certain executives whose benefits under the 401(k) Plan and ESOP are limited by tax law limitations applicable to tax-qualified plans. The Supplemental DC Plan requires a contribution by the Bank for each participant who also participates in the 401(k) Plan and ESOP equal to the amount that would have been contributed under the terms of the of the 401(k) Plan and ESOP but for the tax law limitations, less the amount actually contributed under the 401(k) Plan and ESOP. The Supplemental DC Plan provides for a phantom stock allocation for qualified contributions that may not be accrued in the qualified ESOP and for matching contributions that may not be accrued in the qualified 401(k) Plan due to tax law limitations. Under the Supplemental 401(k) provision, the estimated expense for the year ending December 31, 2015 , 2014 and 2013 was $11,500 , $10,500 and $7,000 , respectively, and included the matching contributions plus interest credited at an annual rate equal to the ten-year bond-equivalent yield on U.S. Treasury securities. Under the Supplemental ESOP provision, the estimated expense for the year ending December 31, 2015 , 2014 and 2013 was $54,000 , $48,000 and $45,000 , respectively. The phantom equity is treated as equity awards (expensed at the time of allocation) and not liability awards which would require periodic adjustment to market, as participants do not have an option to take their distribution in cash. The Amended and Restated Long-Term Incentive Plan Upon stockholders’ approval of the Amended and Restated Long-Term Incentive Plan on April 4, 2014, shares available for stock awards and stock options under the 2008 Long-Term Equity Incentive Plan were reserved for issuance under the new Amended and Restated Long-Term Incentive Plan. No additional grants of stock awards and stock options will be made under the 2008 Long-Term Equity Incentive Plan. The new plan authorized the issuance of up to 3,686,510 shares of Company common stock with no more than 2,100,000 shares permitted to be issued as stock awards. Shares previously awarded under the 2008 plans that are subsequently forfeited or expire may also be issued under the new plan. Stock Awards As a general rule, restricted stock grants are held in escrow for the benefit of the award recipient until vested. Awards outstanding generally vest in three or five annual installments, commencing one year from the date of the award. Additionally, certain awards are two and three -year performance vesting awards, which may or may not vest depending upon the attainment of certain corporate financial targets. Expense attributable to stock awards amounted to $4,625,000 , $6,359,000 and $4,869,000 for the years ended December 31, 2015 , 2014 and 2013 , respectively. A summary status of the granted but unvested stock awards as of December 31, and changes during the year, is presented below: Restricted Stock Awards 2015 2014 2013 Outstanding at beginning of year 846,462 782,213 846,883 Granted 339,936 426,726 386,669 Forfeited (240,191 ) (126,743 ) (68,954 ) Vested (354,461 ) (235,734 ) (382,385 ) Outstanding at the end of year 591,746 846,462 782,213 As of December 31, 2015 , unrecognized compensation cost relating to unvested restricted stock totaled $1.8 million . This amount will be recognized over a remaining weighted average period of 2.1 years. Stock Options Each stock option granted entitles the holder to purchase one share of the Company’s common stock at an exercise price not less than the fair value of a share of the Company’s common stock at the date of grant. Options generally vest over a five -year period from the date of grant and expire no later than 10 years following the grant date. Additionally, certain options are three -year performance vesting options, which may or may not vest depending upon the attainment of certain corporate financial targets. A summary of the status of the granted but unexercised stock options as of December 31, and changes during the year is presented below: 2015 2014 2013 Number of stock options Weighted average exercise price Number of stock options Weighted average exercise price Number of stock options Weighted average exercise price Outstanding at beginning of year 1,284,321 $ 15.32 1,233,742 $ 15.24 4,152,016 $ 17.50 Granted 65,972 16.38 171,935 16.44 85,250 15.23 Exercised (201,320 ) 15.72 (9,678 ) 12.11 (28,464 ) 12.41 Forfeited (62,287 ) 14.93 (4,178 ) 14.50 (53,444 ) 10.34 Expired (2,000 ) 17.94 (107,500 ) 16.54 (2,921,616 ) 18.57 Outstanding at the end of year 1,084,686 $ 15.32 1,284,321 $ 15.32 1,233,742 $ 15.24 The total fair value of options vesting during 2015 , 2014 and 2013 was $274,000 , $438,000 and $696,000 , respectively. Compensation expense of approximately $130,000 , $96,000 and $21,000 is projected for 2016 , 2017 and 2018 , respectively, on stock options outstanding at December 31, 2015 . The following table summarizes information about stock options outstanding at December 31, 2015 : Options Outstanding Options Exercisable Range of exercise prices Number of options outstanding Average remaining contractual life Weighted average exercise price Number of options exercisable Weighted average exercise price $10.27-15.23 506,478 4.2 years $ 12.49 465,478 $ 12.27 $16.38-18.87 578,208 3.9 years $ 17.63 355,134 $ 18.05 The stock options outstanding and stock options exercisable at December 31, 2015 have an aggregate intrinsic value of $5,720,000 and $4,703,000 , respectively. The expense related to stock options is based on the fair value of the options at the date of the grant and is recognized ratably over the vesting period of the options. Compensation expense related to the Company’s stock option plan totaled $272,000 , $298,000 and $297,000 for 2015 , 2014 and 2013 , respectively. The estimated fair values were determined on the dates of grant using the Black-Scholes Option pricing model. The fair value of the Company’ stock option awards are expensed on a straight-line basis over the vesting period of the stock option. The risk-free rate is based on the implied yield on a U.S. Treasury bond with a term approximating the expected term of the option. The expected volatility computation is based on historical volatility over a period approximating the expected term of the option. The dividend yield is based on the annual dividend payment per share, divided by the grant date stock price. The expected option term is a function of the option life and the vesting period. The fair value of the option grants was estimated on the date of grant using the Black-Scholes option-pricing model with the following weighted average assumptions: For the year ended December 31, 2015 2014 2013 Expected dividend yield 3.49 % 3.66 % 3.41 % Expected volatility 21.29 % 20.04 % 33.38 % Risk-free interest rate 1.58 % 0.96 % 0.88 % Expected option life 8 years 6.5 years 8 years The weighted average fair value of options granted during 2015 , 2014 and 2013 was $2.52 , $1.64 and $3.49 per option, respectively.

The tax effects of temporary differences that give rise to significant portions of the deferred tax assets and deferred tax liabilities at December 31, 2015 and 2014 are as follows (in thousands): 2015 2014 Deferred tax assets: Allowance for loan losses $ 23,778 24,160 Post-retirement benefit 10,869 10,658 Deferred compensation 2,825 3,009 Intangibles 481 499 Purchase accounting adjustments 1,464 387 Depreciation 3,868 3,963 SERP 941 949 ESOP 3,254 3,264 Stock-based compensation 5,791 5,734 Non-accrual interest 4,915 5,202 State NOL 139 430 Federal NOL 1,058 1,376 Pension liability adjustments 4,311 5,178 Other 2,048 1,073 Total gross deferred tax assets 65,742 65,882 Valuation Reserve — (242 ) Deferred tax liabilities: Pension expense 10,124 9,925 Deferred loan costs 5,156 4,089 Investment securities, principally due to accretion of discounts 146 311 Originated mortgage servicing rights 347 395 Unrealized gain on securities 2,646 5,191 Total gross deferred tax liabilities 18,419 19,911 Net deferred tax asset $ 47,323 45,729 The 2014 deferred tax expense does not equal the change in net deferred tax assets as a result of deferred taxes recorded in connection with the Team Capital acquisition in the amount of $486,000 . Retained earnings at December 31, 2015 includes approximately $51,800,000 for which no provision for income tax has been made. This amount represents an allocation of income to bad debt deductions for tax purposes only. Events that would result in taxation of these reserves include the failure to qualify as a bank for tax purposes, distributions in complete or partial liquidation, stock redemptions and excess distributions to stockholders. At December 31, 2015 , the Company had an unrecognized tax liability of $20,802,880 with respect to this reserve. At December 31, 2014, the Company had a valuation allowance of $242,000 related to approximately $648,000 of capital loss carryforwards. At December 31, 2015 , the Company did not require a valuation allowance as the statute of limitation on these capital loss carryforwards expired. As a result of the Beacon acquisition in 2011, the Company acquired federal net operating loss carryforwards. There are approximately $3,000,000 of NOL carryforwards available to offset future taxable income as of December 31, 2015 . If not utilized, these carryforwards will expire in 2030. Also, the Company's New Jersey NOL carryforwards in the amount of $1,000,000 which are scheduled to expire in 2033 and Pennsylvania NOL carryforwards in the amount of $1,000,000 , which are set to expire in 2016. The federal NOLs are subject to a combined annual Code Section 382 limitation in the amount of approximately $900,000 . Management has determined that it is more likely than not that it will realize the net deferred tax asset based upon the nature and timing of the items listed above. In order to fully realize the net deferred tax asset, the Company will need to generate future taxable income. Management has projected that the Company will generate sufficient taxable income to utilize the net deferred tax asset; however, there can be no assurance that such levels of taxable income will be generated. The Company’s policy is to report interest and penalties, if any, related to unrecognized tax benefits in income tax expense. The Company did not have any liabilities for uncertain tax positions or any known unrecognized tax benefits at December 31, 2015 and 2014 . The Company and its subsidiaries file a consolidated U.S. Federal income tax return and each entity files a separate state income tax return. The Company's federal income tax returns are open for examination from 2012 and the state income tax returns are open for examination from 2011.

Commitments and Contingencies Disclosure [Abstract]
Commitments, Contingencies and Concentrations of Credit Risk	Commitments, Contingencies and Concentrations of Credit Risk In the normal course of business, various commitments and contingent liabilities are outstanding which are not reflected in the accompanying consolidated financial statements. In the opinion of management, the consolidated financial position of the Company will not be materially affected by the outcome of such commitments or contingent liabilities. A substantial portion of the Bank’s loans are one- to four-family residential first mortgage loans secured by real estate located in New Jersey. Accordingly, the collectability of a substantial portion of the Bank’s loan portfolio and the recovery of a substantial portion of the carrying amount of other real estate owned are susceptible to changes in local real estate market conditions.

Regulatory Capital Requirements

Regulatory Capital Requirements	12 Months Ended
	Dec. 31, 2015
Banking and Thrift [Abstract]
Regulatory Capital Requirements	Regulatory Capital Requirements FDIC regulations require banks to maintain minimum levels of regulatory capital. Under the regulations in effect at December 31, 2015 , the Bank is required to maintain: (1) a Tier 1 capital to total assets leverage ratio of 4.0% ; (2) a common equity Tier 1 capital to risk-based assets ratio of 4.5% ; (3) a Tier 1 capital to risk-based assets ratio of 6.0% ; and (4) a total capital to risk-based assets ratio of 8.0% . In addition to establishing the minimum regulatory capital requirements, the regulations limit capital distributions and certain discretionary bonus payments to management if the institution does not hold a “capital conservation buffer” consisting of 2.5% of common equity Tier 1 capital to risk-weighted asset above the amount necessary to meet its minimum risk-based capital requirements. The capital conservation buffer requirement is being phased in beginning January 1, 2016 at 0.625% of risk-weighted assets and increasing each year until fully implemented at 2.5% on January 1, 2019. Under its prompt corrective action regulations, the FDIC is required to take certain supervisory actions (and may take additional discretionary actions) with respect to an undercapitalized institution. Such actions could have a direct material effect on an institution’s financial statements. The regulations establish a framework for the classification of savings institutions into five categories: well capitalized, adequately capitalized, undercapitalized, significantly undercapitalized, and critically undercapitalized. Generally, an institution is considered well capitalized if it has: a leverage (Tier 1) capital ratio of at least 5.00% ; a common equity Tier 1 risk-based capital ratio of 6.50% ; a Tier 1 risk-based capital ratio of at least 8.00% ; and a total risk-based capital ratio of at least 10.00% . The foregoing capital ratios are based in part on specific quantitative measures of assets, liabilities and certain off-balance sheet items as calculated under regulatory accounting practices. Capital amounts and classifications are also subject to qualitative judgments by the FDIC about capital components, risk weightings and other factors. As of December 31, 2015 and 2014 , the Bank exceeded all minimum capital adequacy requirements to which it is subject. Further, the most recent FDIC notification categorized the Bank as a well-capitalized institution under the prompt corrective action regulations. There have been no conditions or events since that notification that management believes have changed the Bank’s capital classification. The Company is regulated as a bank holding company, and as such, is subject to examination, regulation and periodic reporting under the Bank Holding Company Act, as administered by the Federal Reserve Board (“FRB”). The FRB has adopted capital adequacy guidelines for bank holding companies on a consolidated basis substantially similar to those of the FDIC for the Bank. As of December 31, 2015 and 2014 , the Company was “well capitalized” under FRB guidelines. Regulations of the FRB provide that a bank holding company must serve as a source of strength to any of its subsidiary banks and must not conduct its activities in an unsafe or unsound manner. Under the prompt corrective action provisions discussed above, a bank holding company parent of an undercapitalized subsidiary bank would be directed to guarantee, within limitations, the capital restoration plan that is required of such an undercapitalized bank.

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements The Company utilizes fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures. The determination of fair values of financial instruments often requires the use of estimates. Where quoted market values in an active market are not readily available, the Company 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 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 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 December 31, 2015 and December 31, 2014 . Securities Available for Sale For securities available for sale, 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 which 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 or 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 the Company 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, the Company compares the prices received from the pricing service to a secondary pricing source. Additionally, the Company 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 not historically resulted in adjustment in the prices obtained from the pricing service. The Company also may hold equity securities and debt instruments issued by the U.S. government and U.S. government-sponsored agencies that are traded in active markets with readily accessible quoted market prices that are considered Level 1 inputs. Derivatives The Company records all derivatives on the balance sheet 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. Currently, none of the Company’s derivatives are designated in qualifying hedging relationships. The existing interest rate derivatives result from a service provided to certain qualifying 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 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. The effective portion of changes in the fair value of these derivatives are recorded in accumulated other comprehensive income, and are subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. The ineffective portion of the change in fair value of these derivatives are recognized directly in earnings. The fair value of the Company's derivatives are 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 December 31, 2015 and 2014 . 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 of up to 6% . The Company 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 costs to sell of up to 6% . 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 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. There were no changes to the valuation techniques for fair value measurements during the years ended December 31, 2015 and 2014 . The following tables present the assets and liabilities reported on the consolidated statements of financial condition at their fair value as of December 31, 2015 and 2014 , by level within the fair value hierarchy (in thousands).

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. Investment Securities Held to Maturity For investment securities held to maturity, 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 which 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 or 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 the Company 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, the Company compares the prices received from the pricing service to a secondary pricing source. Additionally, the Company 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 not historically 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. FHLBNY Stock The carrying value of FHLBNY stock was 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. 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 was 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 fair value estimates of commitments to extend credit and letters of credit are deemed immaterial. 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 December 31, 2015 and December 31, 2014 .

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 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 qualifying commercial borrowers in a loan related transaction and, therefore, are not used to manage interest rate risk in the Company’s assets or liabilities. The Company executes interest rate swaps with 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. As the interest rate swaps associated with this program do not meet the strict hedge accounting requirements, changes in the fair value of both the customer swaps and the offsetting swaps are recognized directly in earnings. For the years ended December 31, 2015 and December 31, 2014 , the Company had 23 and 9 interest rate swaps with an aggregate notional amount of $391.4 million and $94.9 million related to this program. Cash flow Hedges of Interest Rate Risk. The Company’s objectives in using interest rate derivatives are 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 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. The effective portion of changes in the fair value of derivatives designated and that qualify as cash flow hedges are recorded in accumulated other comprehensive income and are subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. During the year ended December 31, 2015 , such derivatives were used to hedge the variable cash outflows associated with Federal Home Loan Bank borrowings. The ineffective portion of the change in fair value of the derivatives are recognized directly in earnings. The Company implemented this program during the quarter ended September 30, 2015. During the year ended December 31, 2015 , the Company’s did not record any hedge ineffectiveness. 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 debt. During the next twelve months, the Company estimates that $297,000 will be reclassified as an increase to interest expense. As of December 31, 2015 , the Company had one outstanding interest rate derivative with a notional amount of $40 million that was designated as a cash flow hedge of interest rate risk. The table below presents the fair value of the Company’s derivative financial instruments as well as their classification on the Consolidated Statements of Financial Condition as of December 31, 2015 and 2014 (in thousands): As of December 31, 2015: Asset Derivatives Liability Derivatives Consolidated Statements of Financial Condition Fair Value Consolidated Statements of Financial Condition Fair Value Derivatives not designated as a hedging instruments: Interest rate products Other assets $ 6,849 Other liabilities $ 6,623 Credit contracts Other assets 5 — Total derivatives not designated as hedging instruments $ 6,854 $ 6,623 Derivatives designated as a hedging instrument: Interest rate products Other assets $ — Other liabilities $ 122 Total derivatives designated as hedging instruments $ — $ 122 As of December 31, 2014: Asset Derivatives Liability Derivatives Consolidated Statements of Financial Condition Fair Value Consolidated Statements of Financial Condition Fair Value Derivatives not designated as a hedging instruments: Interest rate products Other assets $ 2,040 Other liabilities $ 2,052 Credit contracts Other assets 6 — Total derivatives not designated as hedging instruments $ 2,046 $ 2,052 The tables below present the effect of the Company’s derivative financial instruments on the Consolidated Statements of Income for the year ended December 31, 2015 and 2014 (in thousands).

The Company also has agreements with certain of its derivative counterparties that contain a provision that if the Company fails to maintain its status as a well / adequate capitalized institution, then the counterparty could terminate the derivative positions and the Company would be required to settle its obligations under the agreements. As of December 31, 2015 , the termination value of derivatives in a net liability position, which includes accrued interest, was $6.8 million. The Company has minimum collateral posting thresholds with certain of its derivative counterparties, and has posted collateral of $7.8 million against its obligations under these agreements. If the Company had breached any of these provisions at December 31, 2015 , it could have been required to settle its obligations under the agreements at the termination value.

Summary of Significant Accounting Policies (Policies)	12 Months Ended

Accounting Policies [Abstract]
Principles of Consolidation	Principles of Consolidation The consolidated financial statements include the accounts of Provident Financial Services, Inc. (the “Company”), The 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	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	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”). Certain reclassifications have been made in the consolidated financial statements to conform with current year classifications. 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	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 maturity dates less than 90 days.
Securities	Securities Securities include investment securities held to maturity and securities available for sale. Securities that the Company has the positive intent and ability to hold to maturity are classified as “investment securities held to maturity” and reported at amortized cost. Securities to be held for indefinite periods of time and not intended to be held to maturity are classified as “securities available for sale” and are reported at estimated fair value, with unrealized gains and losses excluded from earnings and reported as a separate component of stockholders’ equity, net of deferred taxes. The estimated fair values of the Company’s securities are affected by changes in interest rates, credit spreads, and market illiquidity. The Company 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. To determine if a decline in value is other-than-temporary, the Company evaluates 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 such a decline were deemed other-than-temporary, the Company 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. In general, as interest rates rise, the market value of fixed-rate securities decreases and as interest rates fall, the market value of fixed-rate securities increases. The market for non-investment grade, privately issued mortgage-backed securities remains illiquid and prices have not appreciated despite favorable movements in interest rates. To determine if a decline in value is other-than-temporary, the Company evaluates 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. Premiums and discounts on securities are amortized and accreted to income using a method that approximates the interest method over the remaining period to 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	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	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 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 such amounts as an adjustment to 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 collectibility is reasonably assured. An impaired loan is defined as a loan for which it is probable, based on current information, that the lender 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	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	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	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 (generally 25 to 40 years for buildings, and 3 to 5 years for furniture and equipment). 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	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 income in the period that includes the enactment date. 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 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 Trust Company) are not included in the accompanying consolidated statements of financial condition because such properties are not assets of the Bank.
Intangible Assets	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 30 th . 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, 2015. 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 acquisition of Beacon and MDE, and are amortized on an accelerated basis over 12.0 years and 10.4 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 Bank-owned life insurance is accounted for using the cash surrender value method and is recorded at its realizable value.
Employee Benefit Plans	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, 2015 , there were 372,817 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.
Postretirement Benefits Other Than Pensions	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	Derivatives The Company records all derivatives on the Consolidated 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 existing interest rate derivatives result from a service provided to certain qualifying 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 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 Federal Home Loan Bank borrowings. The effective portion of changes in the fair value of these derivatives are recorded in accumulated other comprehensive income, and are subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. The ineffective portion of the change in fair value of these derivatives are recognized directly in earnings. The fair value of the Company's derivatives are determined using discounted cash flow analyses using observable market-based inputs.
Comprehensive Income	Comprehensive Income Comprehensive income is divided into net income and other comprehensive income. Other comprehensive income includes items previously recorded directly to equity, such as unrealized gains and losses on securities available for sale, 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	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	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	Impact of Recent Accounting Pronouncements In February 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 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. The Company is currently assessing the impact that the guidance will have on the Company's consolidated financial statements. In January 2016, the FASB issued ASU No. 2016-01, "Financial Instruments - Overall: Recognition and Measurement of Financial Assets and Liabilities." This ASU addresses certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. This amendment supersedes the guidance to classify equity securities with readily determinable fair values into different categories, requires equity securities to be measured at fair value with changes in the fair value recognized through net income, and simplifies the impairment assessment of equity investments without readily determinable fair values. The amendment requires public business entities that are required to disclose the fair value of financial instruments measured at amortized cost on the balance sheet to measure that fair value using the exit price notion. The amendment requires an entity to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected to measure the liability at fair value in accordance with the fair value option. The amendment requires separate presentation of financial assets and financial liabilities by measurement category and form of financial asset on the balance sheet or in the accompanying notes to the financial statements. The amendment reduces diversity in current practice by clarifying that an entity should evaluate the need for a valuation allowance on a deferred tax asset related to available for sale securities in combination with the entity’s other deferred tax assets. This amendment is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Entities should apply the amendment by means of a cumulative-effect adjustment as of the beginning of the fiscal year of adoption, with the exception of the amendment related to equity securities without readily determinable fair values, which should be applied prospectively to equity investments that exist as of the date of adoption. The Company intends to adopt the accounting standard during the first quarter of 2018, as required, and is currently evaluating the impact that the guidance will have on the Company's consolidated financial statements. In September 2015, the FASB issued ASU No. 2015-16, "Business Combinations, Simplifying the Accounting for Measurement - Period Adjustments." The amendments in this update apply to all entities that have reported provisional amounts for items in a business combination for which the accounting is incomplete by the end of the reporting period in which the combination occurs and during the measurement period have an adjustment to provisional amounts recognized. In these cases, the acquirer must record, in the same period’s financial statements, the effect on earnings of changes in depreciation, amortization, or other income effects, if any, as a result of the change to the provisional amounts, calculated as if the accounting had been completed at the acquisition date. The amendments in this update are effective for fiscal years beginning after December 15, 2015 including interim periods within those fiscal years. The Company’s adoption of this ASU is not expected to have a material impact on its consolidated financial statements. In August 2014, the FASB issued ASU No. 2014-14, “Receivables - Troubled Debt Restructurings by Creditors: Classification of Certain Government-Guaranteed Mortgage Loans upon Foreclosure.” The amendments in this update affect creditors that hold government guaranteed mortgage loans, including those guaranteed by the Federal Housing Administration and the U.S. Department of Veterans Affairs. The amendments in this update require that a mortgage loan be derecognized and that a separate other receivable be recognized upon foreclosure if the following conditions are met: (i) the loan has a government guarantee that is not separable from the loan before foreclosure; (ii) at the time of foreclosure, the creditor has the intent to convey the real estate property to the guarantor and make a claim on the guarantee, and the creditor has the ability to recover under that claim; and (iii) at the time of foreclosure, any amount of the claim that is determined on the basis of the fair value of the real estate is fixed. Upon foreclosure, the separate other receivable should be measured based on the amount of the loan balance (principal and interest) expected to be recovered from the guarantor. The amendments in this update are effective for public business entities for annual periods, and interim periods within those annual periods, beginning after December 15, 2014. The Company's adoption of this ASU did not have a significant impact on its consolidated financial statements. In June 2014, the FASB issued ASU No. 2014-12, "Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period," which requires that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition. This update is effective for interim and annual periods beginning after December 15, 2015. The amendments can be applied prospectively to all awards granted or modified after the effective date or retrospectively to all awards with performance targets that are outstanding as of the beginning of the earliest annual period presented and to all new or modified awards thereafter. Early adoption is permitted. The Company does not expect that the adoption of this guidance will have a significant impact on the Company’s consolidated financial statements. Also in June 2014, the FASB issued ASU No. 2014-11, "Repurchase-to-Maturity Transactions, Repurchase Financings, and Disclosures" which aligns the accounting for repurchase to maturity transactions and repurchase agreements executed as a repurchase financing with the accounting for other typical repurchase agreements. Going forward, these transactions would all be accounted for as secured borrowings. This update is effective for the first interim or annual period beginning after December 15, 2014. In addition the disclosure of certain transactions accounted for as a sale is effective for the first interim or annual period beginning on or after December 15, 2014, and the disclosure for transactions accounted for as secured borrowings is required for annual periods beginning after December 15, 2014, and interim periods beginning after March 15, 2015. Early adoption was prohibited. The Company's adoption of this ASU did not have an impact on its consolidated financial statements.
