Regulatory Matters

Regulatory Matters	12 Months Ended
	Dec. 31, 2019
Banking and Thrift [Abstract]
Regulatory Matters	Regulatory Matters Applicable regulations require the Bank to maintain minimum levels of regulatory capital. Under the regulations in effect at December 31, 2019 , the Bank was required to maintain a minimum ratio of Tier 1 capital to total adjusted assets of 4.0% ; a minimum ratio of common equity T ier 1 capital to risk-weighted assets of 7.0% ; a minimum ratio of Tier 1 capital to risk weighted assets of 8.5% ; and, a minimum ratio of total (core and supplementary) capital to risk-weighted assets of 10.5% . These ratios include the impact of the required capital conservation buffer. With its conversion to a bank holding company on January 31, 2018, the Company became subject to substantially similar consolidated capital requirements imposed by FRB regulation. Under the regulatory framework for prompt corrective action, Federal regulators are 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 the institution’s financial statements. The regulations establish a framework for the classification of banking 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 Tier 1 capital ratio of 5.0% ; a common equity Tier 1 risk-based ratio of at least 6.5% ; a Tier 1 risk-based ratio of at least 8.0% ; and a total risk-based capital ratio of at least 10.0% . At December 31, 2019 and 2018 , the Company and the Bank exceeded all regulatory capital requirements currently applicable . The following is a summary of the Bank and the Company’s regulatory capital amounts and ratios as of December 31, 2019 and 2018 compared to the regulatory minimum capital adequacy requirements and the regulatory requirements for classification as a well-capitalized institution then in effect (dollars in thousands): As of December 31, 2019 Actual For capital adequacy To be well-capitalized Bank: Amount Ratio Amount Ratio Amount Ratio Tier 1 capital (to average assets) $ 779,108 10.03 % $ 310,798 4.00 % $ 388,498 5.00 % Common equity Tier 1 (to risk-weighted assets) 779,108 12.98 420,106 7.00 (1) 390,099 6.50 Tier 1 capital (to risk-weighted assets) 779,108 12.98 510,129 8.50 (1) 480,121 8.00 Total capital (to risk-weighted assets) 797,339 13.29 630,159 10.50 (1) 600,152 10.00 OceanFirst Financial Corp: Tier 1 capital (to average assets) $ 791,746 10.17 % $ 311,289 4.00 % N/A N/A Common equity Tier 1 (to risk-weighted assets) 729,095 12.14 420,273 7.00 (1) N/A N/A Tier 1 capital (to risk-weighted assets) 791,746 13.19 510,331 8.50 (1) N/A N/A Total capital (to risk-weighted assets) 844,977 14.07 630,409 10.50 (1) N/A N/A As of December 31, 2018 Actual For capital adequacy To be well-capitalized Bank: Amount Ratio Amount Ratio Amount Ratio Tier 1 capital (to average assets) $ 712,900 10.01 % $ 284,772 4.000 % $ 355,965 5.00 % Common equity Tier 1 (to risk-weighted assets) 712,900 13.39 339,513 6.375 (2) 346,170 6.50 Tier 1 capital (to risk-weighted assets) 712,900 13.39 419,398 7.875 (2) 426,056 8.00 Total capital (to risk-weighted assets) 730,484 13.72 525,912 9.875 (2) 532,570 10.00 OceanFirst Financial Corp: Tier 1 capital (to average assets) $ 709,972 9.96 % $ 285,199 4.000 % N/A N/A Common equity Tier 1 (to risk-weighted assets) 647,773 12.15 339,791 6.375 (2) N/A N/A Tier 1 capital (to risk-weighted assets) 709,972 13.32 419,742 7.875 (2) N/A N/A Total capital (to risk-weighted assets) 762,556 14.31 526,343 9.875 (2) N/A N/A (1) Includes the Capital Conservation Buffer of 2.500% . (2) Includes the Capital Conservation Buffer of 1.875% . The Bank satisfies the criteria to be “well-capitalized” under the Prompt Corrective Action Regulations. The capital conservation buffer requirement has been phased in, incrementally, over the past four years beginning January 1, 2016. The phase in of the capital conservation buffer started at 0.625% on January 1, 2016, and increased to 1.25% on January 1, 2017, 1.875% on January 1, 2018, and 2.50% on January 1, 2019, when the full capital conservation buffer requirement became effective. Capital distributions and certain discretionary bonus payments are limited if the capital conservation buffer is not maintained. Applicable regulations also impose limitations upon capital distributions by the Company, such as dividends and payments to repurchase or otherwise acquire shares. The Company may not declare or pay cash dividends on or repurchase any of its shares of common stock if the effect thereof would cause stockholders’ equity to be reduced below applicable regulatory capital minimum requirements or if such declaration and payment would otherwise violate regulatory requirements.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Principles of Consolidation The consolidated financial statements include the accounts of OceanFirst Financial Corp. (the “Company”) and its wholly-owned subsidiaries, OceanFirst Bank N.A. (the “Bank”) and OceanFirst Risk Management, Inc., and the Bank’s wholly-owned subsidiaries, OceanFirst REIT Holdings, Inc., and its wholly-owned subsidiary OceanFirst Management Corp., and its wholly-owned subsidiary OceanFirst Realty Corp., OceanFirst Services, LLC and its wholly-owned subsidiary OFB Reinsurance, Ltd., Hooper Holdings, LLC., TRREO Holdings LLC, Casaba Real Estate Holdings Corporation, Cohensey Bridge, L.L.C., Prosperis Financial, LLC and CBNJ Investments Corp. All significant intercompany accounts and transactions have been eliminated in consolidation. Certain amounts previously reported have been reclassified to conform to the current year’s presentation. Business The Bank provides a range of community banking services to customers through a network of branches and offices throughout New Jersey and the metropolitan areas of Philadelphia and New York City. The Bank is subject to competition from other financial institutions and certain technology companies; it is also subject to the regulations of certain regulatory agencies and undergoes periodic examinations by those regulatory authorities. Basis of Financial Statement Presentation The consolidated financial statements have been prepared in conformity with U.S. generally accepted accounting principles. The preparation of the accompanying consolidated financial statements in conformity with these accounting principles requires management to make estimates and assumptions about future events. These estimates and the underlying assumptions affect the amounts of assets and liabilities reported, disclosures about contingent assets and liabilities, and reported amounts of revenues and expenses. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for loan losses, and the evaluation of securities and goodwill for other-than-temporary impairment. 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. As future events and their effects cannot be determined with precision, actual results could differ significantly from these estimates. Changes in those estimates resulting from continuing changes in the economic environment will be reflected in the financial statements in future periods. Cash Equivalents Cash equivalents consist of interest-bearing deposits in other financial institutions. For purposes of the consolidated statements of cash flows, the Company considers all highly liquid debt instruments with original maturities of three months or less to be cash equivalents. Securities Securities include debt securities held-to-maturity, and debt and equity securities available-for-sale. Management determines the appropriate classification at the time of purchase. If management has the positive intent not to sell and the Company would not be required to sell prior to maturity, the securities are classified as held-to-maturity debt securities. Such securities are stated at amortized cost. During 2013, the Company transferred $536.0 million of previously designated available-for-sale debt securities to held-to-maturity designation at estimated fair value. The Company has the ability and intent to hold these securities as an investment until maturity or call. The securities transferred had an unrealized loss of $13.3 million at the time of transfer which continues to be reflected in accumulated other comprehensive income, net of subsequent amortization, which is being recognized over the remaining life of the securities. Securities in the available-for-sale category are securities which the Company may sell prior to maturity as part of its asset/liability management strategy. Such securities are carried at estimated fair value and unrealized gains and losses, net of related tax effect, are excluded from earnings, but are included as a separate component of stockholders’ equity and as part of comprehensive income. Discounts and premiums on securities are accreted or amortized using the level-yield method over the estimated lives of the securities, including the effect of prepayments. Gains or losses on the sale of such securities are included in other income using the specific identification method. Other-Than-Temporary Impairment on Securities One of the significant estimates related to securities is the evaluation for other-than-temporary impairment. If a determination is made that a debt security is other-than-temporarily impaired, the Company will estimate the amount of the unrealized loss that is attributable to credit and all other non-credit related factors. The credit related component will be recognized as an other-than-temporary impairment charge in non-interest income as a component of gain (loss) on securities, net. The non-credit related component will be recorded as an adjustment to accumulated other comprehensive income, net of tax. The evaluation of securities for impairment is a quantitative and qualitative process, which is subject to risks and uncertainties and is intended to determine whether declines in the estimated fair value of investments should be recognized in current period earnings. The risks and uncertainties include changes in general economic conditions, the issuer’s financial condition and/or future prospects, the effects of changes in interest rates or credit spreads and the expected recovery period. On a quarterly basis the Company evaluates the securities portfolio for other-than-temporary impairment. Securities that are in an unrealized loss position are reviewed to determine if an other-than-temporary impairment is present based on certain quantitative factors. The primary factors considered in evaluating whether a decline in value is other-than-temporary include: (a) the length of time and extent to which the estimated fair value has been less than cost or amortized cost and the expected recovery period of the security, (b) the financial condition, credit rating and future prospects of the issuer, (c) whether the debtor is current on contractually obligated interest and principal payments and (d) whether the Company intends to sell the security and whether it is more likely than not that the Company will not be required to sell the security. Loans Receivable Loans receivable, other than loans held-for-sale, are stated at unpaid principal balance, plus unamortized premiums less unearned discounts, net of deferred loan origination and commitment fees and costs, and the allowance for loan losses. Loan origination and commitment fees and certain direct loan origination costs are deferred and the net fee or cost is recognized in interest income using the level-yield method over the contractual life of the specifically identified loans, adjusted for actual prepayments. For each loan class, a loan is considered past due when a payment has not been received in accordance with the contractual terms. Loans which are more than 90 days past due, including impaired loans, and other loans in the process of foreclosure are placed on non-accrual status. Interest income previously accrued on these loans, but not yet received, is reversed in the current period. Any interest subsequently collected is credited to income in the period of recovery only after the full principal balance has been brought current. A loan is returned to accrual status when all amounts due have been received and the remaining principal balance is deemed collectible. A loan is considered impaired when it is deemed probable that the Company will not collect all amounts due according to the contractual terms of the loan agreement. The Company has defined the population of impaired loans to be all non-accrual commercial real estate, multi-family, land, construction and commercial and industrial loans in excess of $250,000 . Impaired loans are individually assessed to determine that the loan’s carrying value is not in excess of the estimated fair value of the collateral or the present value of the loan’s expected future cash flows. Smaller balance homogeneous loans that are collectively evaluated for impairment, such as residential mortgage loans and consumer loans, are specifically excluded from the impaired loan portfolio, except when they are modified in a trouble debt restructuring. Loan losses are charged-off in the period the loans, or portion, thereof are deemed uncollectible, generally after the loan becomes 120 days delinquent. The Company will record a loan charge-off (including a partial charge-off) to reduce a loan to the estimated fair value of the underlying collateral, less cost to sell, if it is determined that it is probable that recovery will come primarily from the sale of the collateral. Purchased credit-impaired (“PCI”) loans are acquired at a discount that is due, in part, to credit quality. PCI loans are initially recorded at fair value (as determined by the present value of expected future cash flows) with no allowance for loan losses. Interest income on loans acquired at a discount is based on the acquired loans’ expected cash flows. The acquired loans may be aggregated and accounted for as a pool of loans if the loans being aggregated have common risk characteristics. A pool is accounted for as a single asset with a single composite interest rate and an aggregate expectation of cash flow. The difference between the undiscounted cash flows expected at acquisition and the investment in the loans, or the “accretable yield”, is recognized as interest income utilizing the level-yield method over the life of each pool. Increases in expected cash flows subsequent to the acquisition are recognized prospectively through adjustment of the yield on the pool over its remaining life, while decreases in expected cash flows are recognized as impairment through a loss provision and an increase in the allowance for loan losses. Therefore, the allowance for loan losses on these impaired pools reflect only losses incurred after the acquisition (representing the present value of all cash flows that were expected at acquisition but currently are not expected to be received). The Bank periodically evaluates the remaining contractual required payments due and estimates of cash flows expected to be collected. These evaluations require the continued use of key assumptions and estimates, similar to the initial estimate of fair value. Changes in the contractually required payments due and estimated cash flows expected to be collected may result in changes in the accretable yield and non-accretable difference or reclassifications between accretable yield and the non-accretable difference. For the pools with better than expected cash flows, the forecasted increase is recorded as an additional accretable yield that is recognized as a prospective increase to interest income on loans. Loans Held for Sale The Company may sell part of its mortgage loan originations in order to manage interest rate risk and liquidity. Prior to 2017, the Bank had generally sold fixed-rate mortgage loans with final maturities in excess of 15 years . However, with few exceptions, since the beginning of 2017 and through 2019, the Bank generally retained newly originated mortgage loans in its portfolio. Given the recent decline in the interest rate environment, the Bank will evaluate the portfolio for potential sales in the future. In determining whether to retain mortgages, management considers the Company’s overall interest rate risk position, the volume of such loans, the loan yield and the types and amount of funding sources. The Company may also retain mortgage loan production in order to improve yields and increase balance sheet leverage. In addition, management periodically considers the sale of commercial and other loans as part of its management of credit risk. Loans held for sale are carried at the lower of unpaid principal balance, net, or estimated fair value on an aggregate basis. Estimated fair value is determined based on bid quotations from securities dealers. Allowance for Loan Losses The allowance for loan losses is a valuation account that reflects probable incurred losses in the loan portfolio. The adequacy of the allowance for loan losses is based on management’s evaluation of the Bank’s past loan loss experience, known and inherent risks in the portfolio, adverse situations that may affect the borrower’s ability to repay, estimated value of any underlying collateral, current economic and regulatory conditions, as well as organizational changes. Additions to the allowance arise from charges to operations through the provision for loan losses or from the recovery of amounts previously charged-off. The allowance is reduced by loan charge-offs. The allowance for loan losses is maintained at an amount management considers sufficient to provide for probable losses. A cquired loans are marked to fair value on the date of acquisition and are evaluated on a quarterly basis to ensure the necessary purchase accounting updates are made in parallel with the allowance for loan loss calculation. Acquired loans that have been renewed since acquisition are included in the allowance for loan loss calculation since these loans have been underwritten to the Bank’s guidelines. Acquired loans that have not been renewed since acquisition, or that have a PCI mark, are excluded from the allowance for loan loss calculation. The Bank calculates a general valuation allowance for these excluded acquired loans without a PCI mark and compares that to the remaining general credit and interest rate marks. To the extent the remaining general credit and interest rate marks exceed the calculated general valuation allowance, no additional reserve is required. If the calculated general valuation allowance exceeds the remaining general credit and interest rate marks, the Bank would record an adjustment to the extent necessary. The Bank’s allowance for loan losses includes specific allowances and a general allowance, each updated on a quarterly basis. A specific allowance is determined for all impaired loans (excluding PCI loans). The Bank defines an impaired loan as all non-accrual commercial real estate, multi-family, land, construction and commercial loans in excess of $250,000 for which it is probable, based on current information, that the Company 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. For collateral dependent loans, the specific allowance represents the difference between the Bank’s recorded investment in the loan, net of any interim charge-offs, and the estimated fair value of the collateral, less estimated selling costs. Impairment for all other impaired loans is calculated based on a combination of the estimated fair value of non-real estate collateral, personal guarantees, or the present value of the expected future cash flows. Generally, for collateral dependent real estate loans, the Bank obtains an updated collateral appraisal once the loan is impaired. For impaired residential real estate loans, the appraisal is generally updated annually if the loan remains delinquent for an extended period. For impaired commercial real estate loans, the Bank assesses whether there has likely been an adverse change in the collateral value supporting the loan. The Bank utilizes information based on its knowledge of changes in real estate conditions in its lending area to identify whether a possible deterioration of collateral value has occurred. Based on the severity of the changes in market conditions, management determines if an updated commercial real estate appraisal is warranted or if downward adjustments to the previous appraisal are warranted. If it is determined that the deterioration of the collateral value is significant enough to warrant ordering a new appraisal, an estimate of the downward adjustments to the existing appraised value is used in assessing if additional specific reserves are necessary until the updated appraisal is received. A general allowance is determined for all loans that are not individually evaluated for impairment (excluding acquired loans that have not been renewed under the Bank’s underwriting criteria). In determining the level of the general allowance, the Bank segments the loan portfolio into the following portfolio segments: residential real estate; consumer; investor-owned commercial real estate; owner-occupied commercial real estate; construction and land; and commercial and industrial. The portfolio segments are further segmented by delinquency status or risk rating. An estimated loss factor is then applied to the outstanding principal loan balance of the delinquency status or risk rating category for each portfolio segment. To determine the loss factor, the Bank utilizes historical loss experience adjusted for certain qualitative factors and the loss emergence period. The Bank’s historical loss experience is based on a rolling 36 -month look-back period for each portfolio segment. The look-back period was selected based on (1) management’s judgment that this period captures sufficient loss events (in both dollar terms and number of individual events) to be relevant; and (2) that the Bank’s underwriting criteria and risk characteristics have remained relatively stable throughout this period. The historical loss experience is adjusted for certain qualitative factors including, but not limited to, (1) delinquency trends, (2) net charge-off trends, (3) nature and volume of the loan portfolio, (4) loan policies and underwriting standards, (5) experience and ability of lending personnel, (6) concentrations of credit, (7) loan review system, and external factors such as (8) changes in current economic conditions, (9) local competition and (10) regulation. Economic factors that the Bank considers in its estimate of the allowance for loan losses include: local and regional trends in economic growth, unemployment and real estate values. The Bank considers the applicability of each of these qualitative factors in estimating the general allowance for each portfolio segment. Each quarter, the Bank considers the current conditions for each of the qualitative factors, as well as a forward looking view on trends and events, to support an assessment unique to each portfolio segment. The Bank calculates and analyzes the loss emergence period on an annual basis or more frequently if conditions warrant. The Bank’s methodology is to use loss events in the past 12 quarters to determine the loss emergence period for each loan segment. The loss emergence period is specific to each portfolio segment. It represents the amount of time that has elapsed between (1) the occurrence of a loss event, which resulted in a potential loss and (2) the confirmation of the potential loss, when the Bank records an initial charge-off or downgrades the risk-rating of the loan to substandard. The Bank also maintains an unallocated portion of the allowance for loan losses. The primary purpose of the unallocated component is to account for the inherent factors that cannot be practically assigned to individual loss categories, including the periodic update of appraisals, subjectivity of the Bank’s credit review and risk rating process, and economic conditions that may not be fully captured in the Bank’s loss history or qualitative factors. Upon completion of the aforementioned procedures, an overall management review is performed including ratio analyses to identify divergent trends compared with the Bank’s own historical loss experience, the historical loss experience of the Bank’s peer group and management’s understanding of general regulatory expectations. Based on that review, management may identify issues or factors that previously had not been considered in the estimation process, which may warrant further analysis or adjustments to estimated loss or qualitative factors applied in the calculation of the allowance for loan losses. Reserve for Repurchased Loans and Loss Sharing Obligations The reserve for repurchased loans and loss sharing obligations relates to potential losses on loans sold which may have to be repurchased due to a violation of representations and warranties and an estimate of the Bank’s obligation under a loss sharing arrangement for loans sold to the Federal Home Loan Bank (“FHLB”) as well as the potential repair requests for guaranteed loans sold to the Small Business Administration (“SBA”). Provisions for losses are charged to gain on sale of loans and credited to the reserve while actual losses are charged to the reserve. The reserve represents the Company’s estimate of the total losses expected to occur and is considered to be adequate by management based upon the Company’s evaluation of the potential exposure related to the loan sale agreements over the period of repurchase risk. The reserve for repurchased loans and loss sharing obligations is included in other liabilities on the Company’s consolidated statement of financial condition as well as SBA repair requests. Other Real Estate Owned Other real estate owned (“OREO”) is carried at the lower of cost or estimated fair value, less estimated costs to sell. When a property is acquired, the excess of the loan balance over estimated fair value is charged to the allowance for loan losses. Operating results from other real estate owned, including rental income, operating expenses, gains and losses realized from the sales of other real estate owned and subsequent write-downs are recorded as incurred. Premises and Equipment Land is carried at cost and premises and equipment, including leasehold improvements, are stated at cost less accumulated depreciation and amortization or, in the case of acquired premises, the value on the acquisition date. Depreciation and amortization are computed using the straight-line method over the estimated useful lives of the assets or leases. Generally, depreciable lives are as follows: computer equipment: 3 years ; furniture, fixtures and other electronic equipment: 5 years ; building improvements: 10 years ; and buildings: 30 years . Repair and maintenance items are expensed and improvements are capitalized. Gains and losses on dispositions are reflected in current operations. Income Taxes The Company utilizes the asset and liability method of accounting for income taxes. Under this method, deferred tax assets and liabilities are recognized for the 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 expected to apply to taxable income in the years 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. Any interest and penalties on taxes payable are included as part of the provision for income taxes. Comprehensive Income Comprehensive income is comprised of net income and other comprehensive income. Other comprehensive income includes items recorded directly in equity, such as unrealized gains or losses on debt securities available-for-sale and accretion of unrealized loss on debt securities reclassified to held-to-maturity. Bank Owned Life Insurance Bank Owned Life Insurance (“BOLI”) is accounted for using the cash surrender value method and is recorded at its realizable value. Part of the Company’s BOLI is invested in a separate account insurance product which is invested in a fixed income portfolio. The separate account includes stable value protection which maintains realizable value at book value with investment gains and losses amortized over future periods. Increases in cash surrender value are included in other non-interest income, while proceeds from death benefits are generally recorded as a reduction to the carrying value. Intangible Assets Intangible assets resulting from acquisitions under the acquisition method of accounting consist of goodwill and core deposit intangible. Goodwill represents the excess of the purchase price over the estimated fair value of identifiable net assets acquired through purchase acquisitions. 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. 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 August 31, 2019 . Based upon its qualitative assessment of goodwill, the Company concluded that goodwill was not impaired and no further quantitative analysis was warranted. 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 throughout New Jersey and the metropolitan areas of Philadelphia and New York City . 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 net income available to common stockholders by the weighted average number of shares of common stock outstanding. Diluted earnings per share is calculated by dividing net income available to common stockholders by the weighted average number of shares of common stock outstanding plus potential common stock, utilizing the treasury stock method. All share amounts exclude unallocated shares of stock held by the Employee Stock Ownership Plan (“ESOP”) and the 2006 and 2011 Incentive Plans (refer to Note 12 Incentive Plan, for further discussion). Impact of New Accounting Pronouncements Accounting Pronouncements Adopted in 2019 In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842).” This ASU requires all lessees to recognize a lease liability and a right-of-use asset, measured at the present value of the future minimum lease payments, at the lease commencement date. Lessor accounting remains largely unchanged under the new guidance. The guidance is effective for fiscal years beginning after December 15, 2018, including interim reporting periods within that reporting period, with early adoption permitted. A modified retrospective approach may be applied for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements On July 30, 2018, the FASB issued ASU 2018-11, “Leases (Topic 842) Targeted Improvements”, which provided an option to apply the transition provisions of the new standard at the adoption date rather than the earliest comparative period presented. Additionally, the ASU provides a practical expedient permitting lessors to not separate non-lease components from the associated lease component if certain conditions are met. The Company adopted this ASU in its entirety on January 1, 2019, and has appropriately reflected the changes throughout the Company’s consolidated financial statements. The Company elected to apply the new standard as of the adoption date and will not restate comparative prior periods. Additionally, the Company elected to apply the package of practical expedients standard under which the Company need not reassess whether any expired or existing contracts are leases or contain leases, the Company need not reassess the lease classification for any expired or existing lease, and the Company need not reassess initial direct costs for any existing leases. The adoption of this ASU resulted in the recognition of a right-of-use asset of $20.6 million in other assets and a lease liability of $20.7 million in other liabilities. Refer to Note 17 Leases, for additional information. In March 2017, the FASB issued ASU 2017-08, “Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20) - Premium Amortization on Purchased Callable Debt Securities.” This ASU requires the amortization of premiums to the earliest call date on debt securities with call features that are explicit, noncontingent and callable at fixed prices and on preset dates. This ASU does not impact securities held as a discount, as the discount continues to be amortized to the contractual maturity. The guidance is effective for fiscal years beginning after December 15, 2018, with early adoption permitted, including adoption in an interim period. The amendments in this ASU should be applied on a modified retrospective basis through a cumulative-effect adjustment directly to retained earnings as of the beginning of the period of adoption. The adoption of this update did not have an impact on the Company’s consolidated financial statements. In August 2017, the FASB issued ASU 2017-12, “Derivatives and Hedging (Topic 815) - Targeted Improvements to Accounting for Hedging Activities.” The amendments in this ASU was issued to better align an entity’s risk management activities and financial reporting for hedging relationships through changes to both the designation and measurement guidance for qualifying hedging relationships and the presentation of hedge results. As a result, the amendments expand and refine hedge accounting for both nonfinancial and financial risk components and align the recognition and presentation of the effects of the hedging instrument and the hedged item in the financial statements. Current GAAP contains limitations on how an entity can designate the hedged risk in certain cash flow and fair value hedging relationships. To address those current limitations, the amendments in this ASU permit hedge accounting for risk components in hedging relationships involving nonfinancial risk and interest rate risk. In addition, the amendments in this ASU change the guidance for designating fair value hedges of interest rate risk and for measuring the change in fair value of the hedged item in fair value hedges of interest rate risk. The amendments in this ASU are effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Early adoption was permitted. The Company does not enter into derivatives that are designated as hedging instruments and as such, the adoption of this ASU did not have an impact on the Company’s consolidated financial statements. In February 2018, the FASB issued ASU 2018-02, “Income Statement - Reporting Comprehensive Income (Topic 220) - Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income.” This ASU was issued to address a narrow-scope financial reporting issue that arose as a result of the enactment of the Tax Cuts and Jobs Act (“Tax Reform”) on December 22, 2017. The objective of ASU 2018-02 is to address the tax effects of items within accumulated other comprehensive income (referred to as “stranded tax effects”) that do not reflect the appropriate tax rate enacted in the Tax Reform. As a result, the ASU 2018-02 allows a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the newly enacted federal corporate income tax rate. The amount of the reclassification would be the difference between the historical corporate income tax rate of 35 percent and the newly enacted corporate income tax rate of 21 percent. ASU 2018-02 is effective for fiscal years beginning after December 15, 2018, with early adoption permitted, including adoption in an interim period. The amendments in this ASU may be applied retrospectively to each period in which the effect of the change in the U.S. Federal corporate income tax rate in the Tax Reform is recognized. The Company has early adopte

Refer to Note 15 Fair Value Measurements, for a discussion of the fair value hierarchy. Securities The estimated fair values of the securities were calculated utilizing Level 2 inputs. The securities acquired are bought and sold in active markets. Prices for these instruments were obtained through security industry sources that actively participate in the buying and selling of securities. Loans The acquired loan portfolio was valued utilizing Level 3 inputs and included the use of present value techniques employing cash flow estimates and 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, the Company 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 acquired bank. The adjustment related to qualitative factors was impacted by general economic conditions and the risk related to lack of experience with the originator’s underwriting process. To calculate the specific credit fair value adjustment, the Company reviewed the acquired loan portfolio for loans meeting the definition of an impaired loan with deteriorated credit quality. Loans meeting these criteria 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 which will be recognized over the life of the loans on a level yield basis as an adjustment to yield. Premises and Equipment Fair values are based upon appraisals from independent third parties. In addition to owned properties, Sun operated twenty one properties subject to lease agreements, and Capital Bank operated one property subject to a lease agreement. Deposits and Core Deposit Premium Core deposit premium represents the value assigned to non-interest-bearing demand deposits, interest-bearing checking, money market and saving accounts acquired as part of the acquisition. The core deposit premium value represents the future economic benefit, including the present value of future tax benefits, of the potential cost saving from acquiring the core deposits as part of an acquisition compared to the cost of alternative funding sources and is valued utilizing Level 2 inputs. The core deposit premium totaled $11.9 million and $2.7 million , for the acquisitions of Sun and Capital Bank, respectively, and is being amortized over its estimated useful life of approximately 10 years using an accelerated method. 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 is valued utilizing Level 2 inputs.

The Company concluded that these corporate debt securities were only temporarily impaired at December 31, 2019 . In concluding that the impairments were only temporary, the Company considered several factors in its analysis. The Company noted that each issuer made all the contractually due payments when required. There were no defaults on principal or interest payments and no interest payments were deferred. Based on management’s analysis of each individual security, the issuers appear to have the ability to meet debt service requirements over the life of the security. Furthermore, the Company does not intend to sell these corporate debt securities and it is more likely than not that the Company will not be required to sell the securities. Historically, the Company has not utilized securities sales as a source of liquidity. The Company’s long range liquidity plans indicate adequate sources of liquidity outside the securities portfolio. The mortgage-backed securities are issued and guaranteed by either the Federal Home Loan Mortgage Corporation (“FHLMC”), the Federal National Mortgage Association (“FNMA”), the Government National Mortgage Association (“GNMA”), or the Small Business Administration (“SBA”), corporations which are chartered by the United States Government and whose debt obligations are typically rated AA+ by one of the internationally-recognized credit rating services. The Company considers the unrealized losses to be the result of changes in interest rates which over time can have both a positive and negative impact on the estimated fair value of the mortgage-backed securities. The Company does not intend to sell these securities and it is more likely than not that the Company will not be required to sell the securities before recovery of their amortized cost. As a result, the Company concluded that these securities were only temporarily impaired at December 31, 2019 . State and municipal obligations are securities issued by state and local governments for various purposes. The Company is not aware of any information subsequent to the purchase of any state and municipal obligation that indicates an inability on the part of an issuer to meet all of its financial commitments. The weighted average credit rating of these securities is Aa/AA with no credit rating below A3/A-. The Company has the ability and stated intention to hold these securities to maturity at which time the Company expects to receive full repayment. Current unrealized losses are considered to be the result of changes in interest rates which over time can have both a positive and negative impact on the estimated fair value of the securities. As a result, the Company concluded that these securities were only temporarily impaired as of December 31, 2019 .

At December 31, 2019, there were no loans that were ninety days or greater past due and still accruing interest. Non-accrual loans include both smaller balance homogeneous loans that are collectively evaluated for impairment and individually classified impaired loans. The Company categorizes all commercial and commercial real estate loans, except for small business loans, into risk categories based on relevant information about the ability of borrowers to service their debt such as: current financial information, historical payment experience, credit documentation and current economic trends, among other factors. The Company uses the following definitions for risk ratings: Pass : Loans classified as Pass are well protected by the paying capacity and net worth of the borrower. Special Mention : Loans classified as Special Mention have a potential weakness that deserves management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loan or of the Bank’s credit position at some future date. Substandard : Loans classified as Substandard are inadequately protected by the current net worth and paying capacity of the borrower or of the collateral pledged, if any. Loans so classified have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the Company will sustain some loss if the deficiencies are not corrected. Doubtful : Loans classified as Doubtful have all the weaknesses inherent in those classified as Substandard, with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions and values, highly questionable and improbable. As of December 31, 2019 and 2018 , and based on the most recent analysis performed, the risk category of loans by loan portfolio segment, excluding PCI loans, is as follows (in thousands): Pass Special Substandard Doubtful Total December 31, 2019 Commercial and industrial $ 378,154 $ 2,657 $ 15,280 $ — $ 396,091 Commercial real estate – owner occupied 756,592 3,985 31,364 — 791,941 Commercial real estate – investor 2,240,104 23,559 21,035 — 2,284,698 $ 3,374,850 $ 30,201 $ 67,679 $ — $ 3,472,730 December 31, 2018 Commercial and industrial $ 291,265 $ 2,777 $ 10,952 $ — $ 304,994 Commercial real estate – owner occupied 706,825 3,000 30,550 — 740,375 Commercial real estate – investor 1,966,495 23,727 24,988 — 2,015,210 $ 2,964,585 $ 29,504 $ 66,490 $ — $ 3,060,579 For residential and consumer loans, the Company evaluates credit quality based on the aging status of the loan, which was previously presented, and by payment activity. The following table presents the recorded investment in residential and consumer loans based on payment activity as of December 31, 2019 and 2018 , excluding PCI loans (in thousands): Residential Consumer December 31, 2019 Performing $ 2,313,640 $ 405,103 Non-performing 7,181 2,733 $ 2,320,821 $ 407,836 December 31, 2018 Performing $ 2,036,897 $ 472,033 Non-performing 7,389 2,914 $ 2,044,286 $ 474,947 The recorded investment in residential and consumer loans collateralized by residential real estate, which are in the process of foreclosure, amounted to $1.8 million at December 31, 2019 . The amount of foreclosed residential real estate property held by the Company was $51,000 at December 31, 2019 . The Company classifies certain loans as troubled debt restructurings when credit terms to a borrower in financial difficulty are modified. The modifications may include a reduction in rate, an extension in term, the capitalization of past due amounts and/or the restructuring of scheduled principal payments. One-to-four family and consumer loans where the borrower’s debt is discharged in a bankruptcy filing are also considered troubled debt restructurings. For these loans, the Bank retains its security interest in the real estate collateral. Included in the non-accrual loan total at December 31, 2019 , 2018 and 2017 were $6.6 million , $3.6 million , and $8.8 million , respectively, of troubled debt restructurings. At December 31, 2019 , there were $476,000 specific reserves allocated to loans which were classified as troubled debt restructurings. At December 31, 2018 and 2017, there were no specific reserves allocated to loans which were classified as troubled debt restructurings. Non-accrual loans which become troubled debt restructurings are generally returned to accrual status after six months of performance. In addition to the troubled debt restructurings included in non-accrual loans, the Company also has loans classified as accruing troubled debt restructuring at December 31, 2019 , 2018 and 2017 , which totaled $18.0 million , $22.9 million , and $33.3 million , respectively. Troubled debt restructurings are considered in the allowance for loan losses similar to other impaired loans.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The provision (benefit) for income taxes for the years ended December 31, 2019 , 2018 and 2017 consists of the following (in thousands): For the Year Ended December 31, 2019 2018 2017 Current Federal $ 1,991 $ 18,030 $ (12,754 ) State 740 108 169 Total current 2,731 18,138 (12,585 ) Deferred Federal 18,846 (4,568 ) 35,440 State (2,793 ) — — Total deferred 16,053 (4,568 ) 35,440 $ 18,784 $ 13,570 $ 22,855 Included in other comprehensive income is income tax expense attributable to the net accretion of unrealized losses on debt securities available-for-sale arising during the year in the amount of $874,000 , $1.1 million , and $276,000 for the years ended December 31, 2019 , 2018 and 2017 , respectively. Effective January 1, 2017, the Company adopted ASU 2016-09 “Compensation - Stock Compensation,” which decreased income tax expense by $1.8 million for the year ended December 31, 2017. Under the ASU, the tax benefits of exercised stock options and vested stock awards are recognized as a benefit to income tax expense in the reporting period which they occur. A reconciliation between the provision for income taxes and the expected amount computed by multiplying income before the provision for income taxes times the applicable statutory Federal income tax rate for the years ended December 31, 2019 , 2018 and 2017 is as follows (in thousands): For the Year Ended December 31, 2019 2018 2017 Income before provision for income taxes $ 107,358 $ 85,502 $ 65,325 Applicable statutory Federal income tax rate 21.0 % 21.0 % 35.0 % Computed “expected” Federal income tax expense $ 22,545 $ 17,955 $ 22,864 (Decrease) increase in Federal income tax expense resulting from Tax exempt interest (665 ) (615 ) (839 ) ESOP fair market value adjustment 77 125 223 ESOP dividends (151 ) (136 ) (230 ) Earnings on BOLI (1,138 ) (1,072 ) (1,155 ) Merger related expenses 297 322 478 State income taxes net of Federal benefit 583 85 110 Stock compensation (386 ) (758 ) (1,823 ) Revaluation of state deferred tax asset (2,205 ) — — Impact of Tax Cuts and Jobs Act (“Tax Reform”) — (1,854 ) 3,643 Reclassification of certain tax effect from accumulated other comprehensive income (221 ) (586 ) — Other items, net 48 104 (416 ) $ 18,784 $ 13,570 $ 22,855 The tax effects of temporary differences that give rise to significant portions of the deferred tax assets and deferred tax liabilities at December 31, 2019 and 2018 are presented in the following table (in thousands): December 31, 2019 2018 Deferred tax assets: Allowance for loan losses $ 4,107 $ 3,501 Reserve for repurchased loans 112 55 Reserve for uncollected interest 212 119 Incentive compensation 1,397 1,302 Deferred compensation 591 529 Other reserves 2,737 334 Stock plans 1,270 950 ESOP 178 142 Purchase accounting adjustments 8,475 16,142 Net operating loss carryforward related to acquisition 39,519 44,436 Other real estate owned — 90 Unrealized loss on securities 826 1,225 Unrealized loss on properties available-for-sale 1,438 1,266 Federal and state alternative minimum tax 4,746 1,410 Total gross deferred tax assets 65,608 71,501 Deferred tax liabilities: Investments, discount accretion (380 ) (232 ) Deferred loan and commitment costs, net (2,379 ) (1,478 ) Premises and equipment, differences in depreciation (7,340 ) (4,350 ) Undistributed REIT income (4,735 ) (1,730 ) Other (707 ) (334 ) Total gross deferred tax liabilities (15,541 ) (8,124 ) Net deferred tax assets $ 50,067 $ 63,377 The 2019 deferred tax expense does not equal the change in net deferred tax assets as a result of deferred taxes recorded in connection with the Capital Bank acquisition of approximately $3.1 million . The Company has Federal net operating losses from the acquisitions of Colonial American, Cape and Sun. At December 31, 2019 and 2018 , the net operating losses from Colonial American were $4.9 million and $5.3 million , respectively. These net operating losses are subject to annual limitation under Code Section 382 of approximately $330,000 , and will expire between 2029 and 2034. At December 31, 2019 and 2018 , the net operating losses from Cape were $0 and $3.0 million , respectively. These net operating losses were subject to annual limitation under Code Section 382 of approximately $4.5 million . At December 31, 2019 and 2018 , the net operating losses from Sun were $175.9 million and $198.9 million , respectively. These net operating losses are subject to annual limitation under Code Section 382 of approximately $23.3 million , which will expire in 2022 and $9.3 million , which will expire between 2029 and 2036. As of December 31, 2019 and 2018 , the Company had $1.8 million of New Jersey AMA Tax Credits. These credits do not expire. As of December 31, 2019 and 2018 , the Company had $1.0 million of AMT Tax Credits that were part of the Cape acquisition and $2.3 million of AMT Tax Credits that were part of the Sun acquisition. These credits are subject to the same Code Section 382 limitation as indicated above but do not expire. At December 31, 2019 , 2018 and 2017 , the Company determined that it is not required to establis h a valuation reserve for the remaining net deferred tax assets since it is “more likely than not” that the net deferred tax assets will be realized through future reversals of existing taxable temporary differences, future taxable income and tax planning strategies. The conclusion that it is “more likely than not” that the remaining net deferred tax assets will be realized is based on the history of earnings and the prospects for continued growth. Management will continue to review the tax criteria related to the recognition of deferred tax assets. Retained earnings at December 31, 2019 includes approximately $10.8 million 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 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, 2019 , the Company had an unrecognized deferred tax liability of $2.6 million with respect to this reserve. There were no unrecognized tax benefits for the years ended December 31, 2019 , 2018 and 2017 . The tax years that remain subject to examination by the Federal government and the state of New York include the years ended December 31, 2016 and forward. The tax years that remain subject to examination by the state of New Jersey include the years ended December 31, 2015 and forward. On July 1, 2018, New Jersey enacted changes to the corporate business tax laws. This legislation required a combined group to file combined returns for tax years beginning in 2019 and thereafter. However, due to technical issues and inconsistencies with existing tax law, it was initially determined that the tax law change did not have an impact on deferred taxes. In December 2019, the State of New Jersey issued a clarifying technical bulletin related to the impact of the new tax legislation enacted in July 2018. This technical bulletin provided clarification to the combined income tax reporting for certain members of a unitary business group. Accordingly, this required a revaluation of some of the Company’s deferred tax assets. As a result of the revaluation of the state deferred tax assets, the Company recognized additional income tax benefit of $2.2 million for the year ended December 31, 2019 . With the enactment of the Tax Reform on December 22, 2017, the federal corporate income tax rate was reduced from 35% to 21% effective January 1, 2018. Accounting guidance requires that the effect of income tax law changes on deferred taxes should be recognized as a component of income tax expense related to continuing operations, but also to items initially recognized in other comprehensive income. As a result of the reduction in the U.S. federal statutory income tax rate, the Company recognized additional income tax benefit of $1.9 million for the year ended December 31, 2018 and additional income tax expense of $3.6 million for the year ended December 31, 2017. Because accounting guidance requires the effect of income tax law changes on deferred taxes to be recognized as a component of income tax expense related to continuing operations, this additional income tax expense included $1.8 million related to items recognized in other comprehensive income. These amounts will continue to be reported as separate components of accumulated other comprehensive income until such time as the underlying transactions from which such amounts arose are settled through continuing operations. At such time, the reclassification from accumulated other comprehensive income will be recognized as a net tax benefit. The amount included in accumulated other comprehensive income at December 31, 2019 , subject to reclassification, was $1.1 million .

Employee Stock Ownership Plan

Employee Stock Ownership Plan	12 Months Ended

Retirement Benefits [Abstract]
Employee Stock Ownership Plan	Employee Stock Ownership Plan The Bank maintains an Employee Stock Ownership Plan (“ESOP”). All full-time employees are eligible to participate in the ESOP after they attain age 21 and complete one year of service during which they work at least 1000 hours . ESOP shares are allocated among participants on the basis of compensation earned during the year. Employees are fully vested in their ESOP account after the completion of five years of credited service or completely if service was terminated due to death, retirement, disability or change in control of the Company. ESOP participants are entitled to receive distributions from the ESOP account only upon termination of service, which includes retirement and death except that a participant may elect to have dividends distributed as a cash payment on a quarterly basis. The ESOP originally borrowed $13.4 million from the Company to purchase 2,013,137 shares of common stock. On May 12, 1998, the initial loan agreement was amended to allow the ESOP to borrow an additional $8.2 million in order to fund the purchase of 633,750 shares of common stock. At the same time, the term of the loan was extended from the initial twelve years to thirty years . On May 1, 2018, the loan agreement was amended to allow the ESOP to borrow an additional $8.4 million in order to fund the purchase of 292,592 shares of common stock. At the same time, the fixed interest rate of the loan was reduced from 8.25% to 3.25% . The amended loan is to be repaid from contributions by the Bank to the ESOP trust. The Bank is required to make contributions to the ESOP in amounts at least equal to the principal and interest requirement of the debt. The Bank’s obligation to make such contributions is reduced to the extent of any dividends paid by the Company on unallocated shares and any investment earnings realized on such dividends. As of December 31, 2019 and 2018 , contributions to the ESOP, which were used to fund principal and interest payments on the ESOP debt, totaled $1.5 million and $1.4 million , respectively. During 2019 and 2018 , $357,000 and $287,000 , respectively, of dividends paid on unallocated ESOP shares were used for debt service. At December 31, 2019 and 2018 , the loan had an outstanding balance of $9.3 million and $10.4 million , respectively, and the ESOP had unallocated shares of 459,711 and 525,241 , respectively. At December 31, 2019 , the unallocated shares had a fair value of $11.7 million . The unamortized balance of the ESOP is shown as unallocated common stock held by the ESOP and is reflected as a reduction of stockholders’ equity. For the years ended December 31, 2019 , 2018 and 2017 , the Bank recorded compensation expense related to the ESOP of $1.6 million , $1.6 million , and $919,000 , respectively, including $366,000 , $596,000 , and $637,000 , respectively, representing additional compensation expense to reflect the increase in the average fair value of committed to be released and allocated shares in excess of the Bank’s cost. As of December 31, 2019 , 2,412,132 shares had been allocated to participants and 65,531 shares were committed to be released.

Incentive Plan

Incentive Plan	12 Months Ended

Share-based Payment Arrangement [Abstract]
Incentive Plan	Incentive Plan On April 20, 2006, the OceanFirst Financial Corp. 2006 Stock Incentive Plan, which authorizes the granting of stock options or awards of common stock, was approved by stockholders. On May 5, 2011, the OceanFirst Financial Corp. 2011 Stock Incentive Plan, which also authorizes the granting of stock options or awards of common stock, was approved by stockholders. This plan was subsequently amended on June 2, 2017. In January 2018, the Company implemented a performance-based stock plan for directors and select senior management executives. The purpose of these plans is to attract and retain qualified personnel in key positions, provide officers, employees and non-employee directors (“Outside Directors”) with a proprietary interest in the Company as an incentive to contribute to the success of the Company, align the interests of management with those of other stockholders and reward employees for outstanding performance. All officers, other employees and Outside Directors of the Company and its affiliates are eligible to receive awards under the plans. Under the amended 2011 Stock Incentive Plan, the Company is authorized to issue up to an additional 4,000,000 shares subject to option or, in lieu of options, up to 1,600,000 shares in the form of stock awards. At December 31, 2019 , 261,527 options or 104,611 awards remain to be issued. Under the 2006 Stock Incentive Plan, the Company was authorized to issue up to an additional 1,000,000 shares subject to options, or in lieu of options, up to 333,333 shares in the form of stock awards. At December 31, 2019 , no options or awards remain to be issued. As part of the Cape acquisition, 599,373 options were granted in 2016 for the conversion of outstanding Cape options. These options had a weighted average exercise price of $10.34 per option and were fully vested upon acquisition. As part of the Ocean Shore acquisition, 287,595 options were granted in 2016 for the conversion of outstanding Ocean Shore options. These options had a weighted average exercise price of $9.37 per option and were fully vested upon acquisition. As part of the Sun acquisition, 491,248 options were granted in 2018 for the conversion of outstanding Sun options. These options had a weighted average exercise price of $21.92 per option and were fully vested upon acquisition. The Company will not recognize compensation expense in the future on these options as they have been accounted for as part of the acquisition. Stock awards generally vest at the rate of 20% per year. In 2019 and 2018, the Company granted performance-based awards, which vest in equal amounts over a 3 year period when a specific performance metric has been attained or exceeded. Options expire 10 years from the date of grant and generally vest at the rate of 20% per year. The exercise price of each option equals the closing market price of the Company’s stock on the date of grant. The Company typically issues Treasury shares or authorized but unissued shares to satisfy stock option exercises. The Company recognizes the grant-date fair value of stock options and other stock-based compensation issued to employees in the income statement. The modified prospective transition method was adopted and, as a result, the income statement includes $973,000 , $1.0 million , and $1.2 million , of expense for stock option grants and $2.9 million , $2.0 million , and $1.0 million , of expense for stock award grants, for the years ended December 31, 2019 , 2018 and 2017 , respectively. At December 31, 2019 , the Company had $10.4 million in compensation cost related to non-vested options and stock awards not yet recognized. This cost will be recognized over the remaining vesting period of 3.35 years. The fair value of stock options granted by the Company was estimated through the use of the Black-Scholes option pricing model applying the following assumptions: 2019 2018 2017 Risk-free interest rate 2.63 % 2.65 % 2.31 % Expected option life 7 years 7 years 7 years Expected volatility 21 % 21 % 21 % Expected dividend yield 2.70 % 2.19 % 2.07 % Weighted average fair value of an option share granted during the year $ 4.47 $ 5.44 $ 5.62 Intrinsic value of options exercised during the year (in thousands) 2,994 8,513 7,882 The risk-free interest rate is based on the U.S. Treasury rate with a term equal to the expected option life. The expected option life conforms to the Company’s actual experience. Expected volatility is based on actual historical results. Compensation cost is recognized on a straight line basis over the vesting period. A summary of option activity for the years ended December 31, 2019 , 2018 and 2017 is as follows: 2019 2018 2017 Number of Shares Weighted Average Exercise Price Number of Shares Weighted Average Exercise Price Number of Shares Weighted Average Exercise Price Outstanding at beginning of year 2,340,842 $ 18.25 2,489,314 $ 16.91 2,758,833 $ 14.94 Granted 461,407 25.20 135,107 27.39 335,150 29.01 Assumed in acquisition — — 491,248 21.92 — — Exercised (227,189 ) 11.24 (765,624 ) 17.69 (567,153 ) 14.39 Forfeited (149,158 ) 24.71 (9,203 ) 28.42 (35,099 ) 18.42 Expired (1,870 ) 29.59 — — (2,417 ) 11.70 Outstanding at end of year 2,424,032 $ 19.80 2,340,842 $ 18.25 2,489,314 $ 16.91 Options exercisable 1,612,946 1,604,576 1,608,762 The following table summarizes information about stock options outstanding at December 31, 2019 : Options Outstanding Options Exercisable Exercise Prices Number of Options Weighted Average Remaining Contractual Life Weighted Average Exercise Price Number of Options Weighted Average Remaining Contractual Life Weighted Average Exercise Price $8.45 to 12.95 293,334 1.3 years $ 9.78 290,334 1.3 years $ 9.76 12.95 to 17.45 900,520 3.7 15.45 765,149 3.3 15.13 17.45 to 21.95 196,744 4.2 17.98 196,744 4.2 17.98 21.95 to 26.45 457,563 8.8 24.99 34,570 4.8 23.18 26.45 to 30.95 575,871 5.9 28.21 326,149 4.6 28.04 2,424,032 4.9 years $ 19.80 1,612,946 3.3 years $ 17.29 The aggregate intrinsic value for stock options outstanding and stock options exercisable at December 31, 2019 is $15.4 million and $14.1 million , respectively.

Commitments and Contingencies Disclosure [Abstract]
Commitments, Contingencies and Concentrations of Credit Risk	Commitments, Contingencies and Concentrations of Credit Risk The Company, in the normal course of business, is party to financial instruments and commitments which involve, to varying degrees, elements of risk in excess of the amounts recognized in the consolidated financial statements. These financial instruments and commitments include unused consumer lines of credit and commitments to extend credit. At December 31, 2019 , the following commitments and contingent liabilities existed which are not reflected in the accompanying consolidated financial statements (in thousands): December 31, 2019 Unused consumer and construction loan lines of credit (primarily floating-rate) $ 333,074 Unused commercial loan lines of credit (primarily floating-rate) 451,535 Other commitments to extend credit: Fixed-Rate 197,940 Adjustable-Rate 2,764 Floating-Rate 127,010 The Company’s fixed-rate loan commitments expire within 90 days of issuance and carried interest rates ranging from 2.25% to 6.75% at December 31, 2019 . The Company’s maximum exposure to credit losses in the event of nonperformance by the other party to these financial instruments and commitments is represented by the contractual amounts. The Company uses the same credit policies in granting commitments and conditional obligations as it does for financial instruments recorded in the consolidated statements of financial condition. These commitments and obligations do not necessarily represent future cash flow requirements. The Company evaluates each customer’s creditworthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary, is based on management’s assessment of risk. Substantially all of the unused consumer and construction loan lines of credit are collateralized by mortgages on real estate. At December 31, 2019 , the Company is obligated under noncancelable operating leases for premises and equipment. Rental and lease expense under these leases aggregated approximately $5.0 million , $5.2 million , and $3.2 million for the years ended December 31, 2019 , 2018 and 2017 , respectively. Refer to Note 17 Leases, for the projected minimum lease commitments as of December 31, 2019 . The Company grants one-to-four family and commercial first mortgage real estate loans to borrowers primarily located throughout New Jersey and the metropolitan areas of Philadelphia and New York City. The ability of borrowers to repay their obligations is 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 Company’s lien on the property. Such factors are dependent upon various economic conditions and individual circumstances beyond the Company’s control; the Company is, therefore, subject to risk of loss. A decline in real estate values could cause some residential and commercial real estate loans to become inadequately collateralized, which would expose the Bank to a greater risk of loss. The Company believes its lending policies and procedures adequately minimize the potential exposure to such risks. Collateral and/or guarantees are required for all loans. The Company is a defendant in certain claims and legal actions arising in the ordinary course of business. Management and its legal counsel are of the opinion that the ultimate disposition of these matters will not have a material adverse effect on the Company’s consolidated financial condition, results of operations or liquidity.

Fair Value Measurements

Fair Value Measurements	12 Months Ended
	Dec. 31, 2019
Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. A fair value measurement assumes that the transaction to sell the asset or transfer the liability occurs in the principal market for the asset or liability or in the absence of a principal market, the most advantageous market for the asset or liability. The price in the principal (or the most advantageous) market used to measure the fair value of the asset or liability shall not be adjusted for transaction costs. An orderly transaction is a transaction that assumes exposure to the market for a period prior to the measurement date to allow for marketing activities that are usual and customary for transactions involving such assets and liabilities; it is not a forced transaction. Market participants are buyers and sellers in the principal market that are (i) independent, (ii) knowledgeable, (iii) able to transact, and (iv) willing to transact. The Company uses valuation techniques that are consistent with the market approach, the income approach and/or the cost approach. The market approach uses prices and other relevant information generated by market transactions involving identical or comparable assets and liabilities. The income approach uses valuation techniques to convert future amounts, such as cash flows or earnings, to a single present amount on a discounted basis. The cost approach is based on the amount that currently would be required to replace the service capacity of an asset (replacement costs). Valuation techniques should be consistently applied. Inputs to valuation techniques refer to the assumptions that market participants would use in pricing the asset or liability. Inputs may be observable, meaning those that reflect the assumptions market participants would use in pricing the asset or liability and developed based on market data obtained from independent sources, or unobservable, meaning those that reflect the reporting entity’s own assumptions about the assumptions market participants would use in pricing the asset or liability and developed based on the best information available in the circumstances. In that regard, a fair value hierarchy has been established for valuation inputs that gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities and the lowest priority to unobservable inputs. Movements within the fair value hierarchy are recognized at the end of the applicable reporting period. There were no transfers between the levels of the fair value hierarchy for the years ended December 31, 2019 , 2018 and 2017 . The fair value hierarchy is as follows: Level 1 Inputs – Unadjusted quoted prices in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date. Level 2 Inputs – Inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. These include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability (for example, interest rates, volatilities, prepayment speeds, loss severities, credit risks and default rates) or inputs that are derived principally from or corroborated by observable market data by correlations or other means. Level 3 Inputs – Significant unobservable inputs that reflect an entity’s own assumptions that market participants would use in pricing the assets or liabilities. Assets and Liabilities Measured at Fair Value A description of the valuation methodologies used for assets and liabilities measured at fair value, as well as the general classification of such instruments pursuant to the valuation hierarchy, is set forth below. Certain financial assets and financial liabilities are measured at fair value on a non-recurring basis, that is, the instruments are not measured at fair value on an ongoing basis but are subject to fair value adjustments in certain circumstances (for example, when there is evidence of impairment). Debt Secur ities Available-For-Sale Debt securities classified as available-for-sale are reported at fair value. Fair value for these debt securities is determined using inputs other than quoted prices that are based on market observable information (Level 2). Level 2 debt securities are priced through third-party pricing services or s ecurity industry sources that actively participate in the buying and selling of securities. Prices obtained from these sources include market quotations and matrix pricing. Matrix pricing is a mathematical technique used principally to value certain debt securities without relying exclusively on quoted prices for the specific securities, but comparing the debt securities to benchmark or comparable debt securities. Equity Investments Equity investments are reported at fair value. Fair value for these investments is determined using a quoted price in an active market or exchange (Level 1). Interest Rate Swaps The Company’s interest rate swaps are reported at fair value utilizing models provided by an independent, third-party and observable market data. When entering into an interest rate swap agreement, the Company is exposed to fair value changes due to interest rate movements, and also the potential nonperformance of our contract counterparty. Other Real Estate Owned and Impaired Loans Other real estate owned and loans measured for impairment based on the fair value of the underlying collateral are recorded at estimated fair value, less estimated selling costs. Fair value is based on independent appraisals. The following table summarizes financial assets and financial liabilities measured at fair value as of December 31, 2019 and 2018 , segregated by the level of the valuation inputs within the fair value hierarchy utilized to measure fair value (in thousands): Fair Value Measurements at Reporting Date Using: Total Fair Value Level 1 Inputs Level 2 Inputs Level 3 Inputs December 31, 2019 Items measured on a recurring basis: Debt securities available-for-sale $ 150,960 $ — $ 150,935 $ 25 Equity investments 10,136 10,136 — — Interest rate swap asset 10,141 — 10,141 — Interest rate swap liability (10,708 ) — (10,708 ) — Items measured on a non-recurring basis: Other real estate owned 264 — — 264 Loans measured for impairment based on the fair value of the underlying collateral 8,794 — — 8,794 December 31, 2018 Items measured on a recurring basis: Debt securities available-for-sale $ 100,717 $ — $ 100,717 $ — Equity investments 9,655 9,655 — — Interest rate swap asset 1,722 — 1,722 — Interest rate swap liability (1,813 ) — (1,813 ) — Items measured on a non-recurring basis: Other real estate owned 1,381 — — 1,381 Loans measured for impairment based on the fair value of the underlying collateral 11,639 — — 11,639 Assets and Liabilities Disclosed at Fair Value A description of the valuation methodologies used for assets and liabilities disclosed at fair value, as well as the general classification of such instruments pursuant to the valuation hierarchy, is set forth below. Cash and Due from Banks For cash and due from banks, the carrying amount approximates fair value. Debt Securities Held-to-Maturity Debt securities classified as held-to-maturity are carried at amortized cost, as the Company has the positive intent and ability to hold these debt securities to maturity. The Company determines the fair value of the debt securities utilizing Level 2 and, infrequently, Level 3 inputs. Most of the Company’s investment and mortgage-backed securities, are fixed income instruments that are not quoted on an exchange, but are bought and sold in active markets. Prices for these instruments are obtained through third-party pricing vendors or security industry sources that actively participate in the buying and selling of debt securities. Prices obtained from these sources include market quotations and matrix pricing. Matrix pricing is a mathematical technique used principally to value certain debt securities without relying exclusively on quoted prices for the specific debt securities, but comparing the debt securities to benchmark or comparable debt securities. Management’s policy is to obtain and review all available documentation from the third-party pricing service relating to their fair value determinations, including their methodology and summary of inputs. Management reviews this documentation, makes inquiries of the third-party pricing service and decides as to the level of the valuation inputs. Based on the Company’s review of the available documentation from the third-party pricing service, management concluded that Level 2 inputs were utilized for all securities except for certain state and municipal obligations known as bond anticipation notes (“BANs”) where management utilized Level 3 inputs. Restricted Equity Investments The fair value for Federal Home Loan Bank of New York and Federal Reserve Bank stock is its carrying value since this is the amount for which it could be redeemed. There is no active market for this stock and the Company is required to maintain a minimum investment as stipulated by the respective agencies. Loans Fair values are estimated for portfolios of loans with similar financial characteristics. Loans are segregated by type such as residential real estate, consumer and commercial. Each loan category is further segmented into fixed and adjustable rate interest terms. Fair value of performing and non-performing loans was estimated by discounting the future cash flows, net of estimated prepayments, at a rate for which similar loans would be originated to new borrowers with similar terms. In accordance with the prospective adoption of ASU 2016-01, the fair value of loans was measured using the exit price notion. Deposits Other than Time Deposits The fair value of deposits with no stated maturity, such as non-interest-bearing demand deposits, savings, and interest-bearing checking accounts and money market accounts is, by definition, equal to the amount payable on demand. The related insensitivity of the majority of these deposits to interest rate changes creates a significant inherent value which is not reflected in the fair value reported. Time Deposits The fair value of time deposits is based on the discounted value of contractual cash flows. The discount rate is estimated using the rates currently offered for deposits of similar remaining maturities. Securities Sold Under Agreements to Repurchase with Retail Customers Fair value approximates the carrying amount as these borrowings are payable on demand and the interest rate adjusts monthly. Borrowed Funds Fair value estimates are based on discounting contractual cash flows using rates which approximate the rates offered for borrowings of similar remaining maturities. The book value and estimated fair value of the Bank’s significant financial instruments not recorded at fair value as of December 31, 2019 and December 31, 2018 are presented in the following tables (in thousands): Fair Value Measurements at Reporting Date Using: Book Value Level 1 Inputs Level 2 Inputs Level 3 Inputs December 31, 2019 Financial Assets: Cash and due from banks $ 120,544 $ 120,544 $ — $ — Debt securities held-to-maturity 768,873 — 774,805 2,485 Restricted equity investments 62,356 — — 62,356 Loans receivable, net and loans held-for-sale 6,207,680 — — 6,173,237 Financial Liabilities: Deposits other than time deposits 5,393,145 — 5,393,145 — Time deposits 935,632 — 936,318 — Federal Home Loan Bank advances and other borrowings 616,061 — 626,225 — Securities sold under agreements to repurchase with retail customers 71,739 71,739 — — December 31, 2018 Financial Assets: Cash and due from banks $ 120,792 $ 120,792 $ — $ — Debt securities held-to-maturity 846,810 — 830,999 1,816 Restricted equity investments 56,784 — — 56,784 Loans receivable, net and loans held-for-sale 5,579,222 — — 5,474,306 Financial Liabilities: Deposits other than time deposits 4,948,325 — 4,948,325 — Time deposits 866,244 — 853,678 — Federal Home Loan Bank advances and other borrowings 548,913 — 554,692 — Securities sold under agreements to repurchase with retail customers 61,760 61,760 — — 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 a limited 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 significant unobservable inputs. 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 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 premises and equipment, Bank Owned Life Insurance, deferred tax assets and goodwill. 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.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives, Hedging Activities and Other Financial Instruments	Derivatives, Hedging Activities and Other Financial Instruments The Company enters into derivative financial instruments which involve, to varying degrees, interest rate, market and credit risk. The Company manages these risks as part of its asset and liability management process and through credit policies and procedures, seeking to minimize counterparty credit risk by establishing credit limits and collateral agreements. The Company utilizes certain derivative financial instruments to enhance its ability to manage interest rate risk that exists as part of its ongoing business operations. The derivative financial instruments entered into by the Company are an economic hedge of a derivative offering to Bank customers. The Company does not use derivative financial instruments for trading purposes. Customer Derivatives – Interest Rate Swaps The Company enters into interest rate swaps that allow commercial loan customers to effectively convert a variable-rate commercial loan agreement to a fixed-rate commercial loan agreement. Under these agreements, the Company enters into a variable-rate loan agreement with a customer in addition to an interest rate swap agreement, which serves to effectively swap the customer’s variable-rate loan into a fixed-rate loan. The Company then enters into a corresponding swap agreement with a third party in order to economically hedge its exposure through the customer agreement. The interest rate swaps with both the customers and third parties are not designated as hedges under FASB Accounting Standards Codification (“ASC”) Topic 815, Derivatives and Hedging, and are marked to market through earnings. As the interest rate swaps are structured to offset each other, changes to the underlying benchmark interest rates considered in the valuation of these instruments do not result in an impact to earnings; however, there may be fair value adjustments related to credit quality variations between counterparties, which may impact earnings as required by FASB ASC Topic 820, Fair Value Measurements. For the periods ended December 31, 2019 and 2018, the Company recognized a loss of $478,000 and $87,000 , respectively, in other income resulting from a fair value adjustment. The notional amount of derivatives not designated as hedging instruments was $337.6 million and $59.3 million at December 31, 2019 and 2018, respectively. The table below presents the fair value of derivatives not designated as hedging instruments as well as their location on the consolidated statements of financial condition (in thousands): Fair Value December 31, Balance Sheet Location 2019 2018 Other assets $ 10,141 $ 1,722 Other liabilities 10,708 1,813 Credit Risk-Related Contingent Features The Company is a party to International Swaps and Derivatives Association agreements with third party broker-dealers that require a minimum dollar transfer amount upon a margin call. This requirement is dependent on certain specified credit measures. The amount of collateral posted with third parties was $13.7 million and $4.1 million at December 31, 2019 and 2018, respectively. The amount of collateral posted with third parties is deemed to be sufficient to collateralize both the fair market value change as well as any additional amounts that may be required as a result of a change in the specified credit measures. The aggregate fair value of all derivative financial instruments in a liability position with credit measure contingencies and entered into with third parties was $10.7 million and $1.8 million at December 31, 2019

Leases [Abstract]
Leases	Leases A lease is defined as a contract, or part of a contract, that conveys the right to control the use of identified property, plant or equipment for a period of time in exchange for consideration. On January 1, 2019, the Company adopted ASU No. 2016-02, “Leases (Topic 842)” and all subsequent ASUs that modified Leases (Topic 842). For the Company, Leases (Topic 842) primarily affected the accounting treatment for operating lease agreements in which the Company is the lessee. The Company’s leases are comprised of real estate property for branches, ATM locations and office space with terms extending through 2050. The majority of the Company’s leases are classified as operating leases, and therefore, were not previously included on the consolidated statements of financial condition. As part of the adoption of Leases (Topic 842), operating lease agreements are required to be recognized on the consolidated statements of financial condition as a right-of-use (“ROU”) asset and a corresponding lease liability. The Company has one existing finance lease (previously referred to as capital leases), which was acquired in the Sun acquisition and has a lease term through 2029. This lease was previously required to be recorded on the Company’s consolidated statements of financial condition. As such, the adoption of Leases (Topic 842) did not have a material impact on the accounting for this lease. The following table represents the classification of the Company’s ROU assets and lease liabilities on the consolidated statements of financial condition (in thousands): December 31, 2019 Lease ROU Assets Classification Operating lease ROU asset Other assets $ 18,682 Finance lease ROU asset Premises and equipment, net 1,534 Total Lease ROU Asset $ 20,216 Lease Liabilities Operating lease liability Other liabilities $ 18,893 Finance lease liability Other borrowings 1,953 Total Lease Liability $ 20,846 The calculated amount of the ROU assets and lease liabilities are impacted by the lease term and the discount rate used to calculate the present value of the minimum lease payments. Lease agreements often include one or more options to renew the lease at the Company’s discretion. If the exercise of a renewal option is considered to be reasonably certain, the Company includes the extended term in the calculation of the ROU asset and lease liability. For the discount rate, Leases (Topic 842) requires the Company to use the rate implicit in the lease, provided the rate is readily determinable. As this rate is rarely determinable, the Company utilizes its incremental borrowing rate, at lease inception, over a similar term. For operating leases existing prior to January 1, 2019, the Company used the incremental borrowing rate for the remaining lease term as of January 1, 2019. For the finance lease, the Company utilized its incremental borrowing rate at lease inception.

(the “Bank”) and OceanFirst Risk Management, Inc., and the Bank’s wholly-owned subsidiaries, OceanFirst REIT Holdings, Inc., and its wholly-owned subsidiary OceanFirst Management Corp., and its wholly-owned subsidiary OceanFirst Realty Corp., OceanFirst Services, LLC and its wholly-owned subsidiary OFB Reinsurance, Ltd., Hooper Holdings, LLC., TRREO Holdings LLC, Casaba Real Estate Holdings Corporation, Cohensey Bridge, L.L.C., Prosperis Financial, LLC and CBNJ Investments Corp. All significant intercompany accounts and transactions have been eliminated in consolidation. Certain amounts previously reported have been reclassified to conform to the current year’s presentation.
Business	Business The Bank provides a range of community banking services to customers through a network of branches and offices throughout New Jersey and the metropolitan areas of Philadelphia and New York City. The Bank is subject to competition from other financial institutions and certain technology companies; it is also subject to the regulations of certain regulatory agencies and undergoes periodic examinations by those regulatory authorities.
Basis of Financial Statement Presentation	Basis of Financial Statement Presentation The consolidated financial statements have been prepared in conformity with U.S. generally accepted accounting principles. The preparation of the accompanying consolidated financial statements in conformity with these accounting principles requires management to make estimates and assumptions about future events. These estimates and the underlying assumptions affect the amounts of assets and liabilities reported, disclosures about contingent assets and liabilities, and reported amounts of revenues and expenses. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for loan losses, and the evaluation of securities and goodwill for other-than-temporary impairment. 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. As future events and their effects cannot be determined with precision, actual results could differ significantly from these estimates. Changes in those estimates resulting from continuing changes in the economic environment will be reflected in the financial statements in future periods.
Cash Equivalents	Cash Equivalents Cash equivalents consist of interest-bearing deposits in other financial institutions. For purposes of the consolidated statements of cash flows, the Company considers all highly liquid debt instruments with original maturities of three months or less to be cash equivalents.
Securities and Other-Than-Temporary Impairments on Securities	Securities Securities include debt securities held-to-maturity, and debt and equity securities available-for-sale. Management determines the appropriate classification at the time of purchase. If management has the positive intent not to sell and the Company would not be required to sell prior to maturity, the securities are classified as held-to-maturity debt securities. Such securities are stated at amortized cost. During 2013, the Company transferred $536.0 million of previously designated available-for-sale debt securities to held-to-maturity designation at estimated fair value. The Company has the ability and intent to hold these securities as an investment until maturity or call. The securities transferred had an unrealized loss of $13.3 million at the time of transfer which continues to be reflected in accumulated other comprehensive income, net of subsequent amortization, which is being recognized over the remaining life of the securities. Securities in the available-for-sale category are securities which the Company may sell prior to maturity as part of its asset/liability management strategy. Such securities are carried at estimated fair value and unrealized gains and losses, net of related tax effect, are excluded from earnings, but are included as a separate component of stockholders’ equity and as part of comprehensive income. Discounts and premiums on securities are accreted or amortized using the level-yield method over the estimated lives of the securities, including the effect of prepayments. Gains or losses on the sale of such securities are included in other income using the specific identification method. Other-Than-Temporary Impairment on Securities One of the significant estimates related to securities is the evaluation for other-than-temporary impairment. If a determination is made that a debt security is other-than-temporarily impaired, the Company will estimate the amount of the unrealized loss that is attributable to credit and all other non-credit related factors. The credit related component will be recognized as an other-than-temporary impairment charge in non-interest income as a component of gain (loss) on securities, net. The non-credit related component will be recorded as an adjustment to accumulated other comprehensive income, net of tax. The evaluation of securities for impairment is a quantitative and qualitative process, which is subject to risks and uncertainties and is intended to determine whether declines in the estimated fair value of investments should be recognized in current period earnings. The risks and uncertainties include changes in general economic conditions, the issuer’s financial condition and/or future prospects, the effects of changes in interest rates or credit spreads and the expected recovery period. On a quarterly basis the Company evaluates the securities portfolio for other-than-temporary impairment. Securities that are in an unrealized loss position are reviewed to determine if an other-than-temporary impairment is present based on certain quantitative factors. The primary factors considered in evaluating whether a decline in value is other-than-temporary include: (a) the length of time and extent to which the estimated fair value has been less than cost or amortized cost and the expected recovery period of the security, (b) the financial condition, credit rating and future prospects of the issuer, (c) whether the debtor is current on contractually obligated interest and principal payments and (d) whether the Company intends to sell the security and whether it is more likely than not that the Company will not be required to sell the security.
Loans Receivable	Loans Receivable Loans receivable, other than loans held-for-sale, are stated at unpaid principal balance, plus unamortized premiums less unearned discounts, net of deferred loan origination and commitment fees and costs, and the allowance for loan losses. Loan origination and commitment fees and certain direct loan origination costs are deferred and the net fee or cost is recognized in interest income using the level-yield method over the contractual life of the specifically identified loans, adjusted for actual prepayments. For each loan class, a loan is considered past due when a payment has not been received in accordance with the contractual terms. Loans which are more than 90 days past due, including impaired loans, and other loans in the process of foreclosure are placed on non-accrual status. Interest income previously accrued on these loans, but not yet received, is reversed in the current period. Any interest subsequently collected is credited to income in the period of recovery only after the full principal balance has been brought current. A loan is returned to accrual status when all amounts due have been received and the remaining principal balance is deemed collectible. A loan is considered impaired when it is deemed probable that the Company will not collect all amounts due according to the contractual terms of the loan agreement. The Company has defined the population of impaired loans to be all non-accrual commercial real estate, multi-family, land, construction and commercial and industrial loans in excess of $250,000 . Impaired loans are individually assessed to determine that the loan’s carrying value is not in excess of the estimated fair value of the collateral or the present value of the loan’s expected future cash flows. Smaller balance homogeneous loans that are collectively evaluated for impairment, such as residential mortgage loans and consumer loans, are specifically excluded from the impaired loan portfolio, except when they are modified in a trouble debt restructuring. Loan losses are charged-off in the period the loans, or portion, thereof are deemed uncollectible, generally after the loan becomes 120 days delinquent. The Company will record a loan charge-off (including a partial charge-off) to reduce a loan to the estimated fair value of the underlying collateral, less cost to sell, if it is determined that it is probable that recovery will come primarily from the sale of the collateral. Purchased credit-impaired (“PCI”) loans are acquired at a discount that is due, in part, to credit quality. PCI loans are initially recorded at fair value (as determined by the present value of expected future cash flows) with no allowance for loan losses. Interest income on loans acquired at a discount is based on the acquired loans’ expected cash flows. The acquired loans may be aggregated and accounted for as a pool of loans if the loans being aggregated have common risk characteristics. A pool is accounted for as a single asset with a single composite interest rate and an aggregate expectation of cash flow. The difference between the undiscounted cash flows expected at acquisition and the investment in the loans, or the “accretable yield”, is recognized as interest income utilizing the level-yield method over the life of each pool. Increases in expected cash flows subsequent to the acquisition are recognized prospectively through adjustment of the yield on the pool over its remaining life, while decreases in expected cash flows are recognized as impairment through a loss provision and an increase in the allowance for loan losses. Therefore, the allowance for loan losses on these impaired pools reflect only losses incurred after the acquisition (representing the present value of all cash flows that were expected at acquisition but currently are not expected to be received). The Bank periodically evaluates the remaining contractual required payments due and estimates of cash flows expected to be collected. These evaluations require the continued use of key assumptions and estimates, similar to the initial estimate of fair value. Changes in the contractually required payments due and estimated cash flows expected to be collected may result in changes in the accretable yield and non-accretable difference or reclassifications between accretable yield and the non-accretable difference. For the pools with better than expected cash flows, the forecasted increase is recorded as an additional accretable yield that is recognized as a prospective increase to interest income on loans.
Loans Held-for-sale	Loans Held for Sale The Company may sell part of its mortgage loan originations in order to manage interest rate risk and liquidity. Prior to 2017, the Bank had generally sold fixed-rate mortgage loans with final maturities in excess of 15 years . However, with few exceptions, since the beginning of 2017 and through 2019, the Bank generally retained newly originated mortgage loans in its portfolio. Given the recent decline in the interest rate environment, the Bank will evaluate the portfolio for potential sales in the future. In determining whether to retain mortgages, management considers the Company’s overall interest rate risk position, the volume of such loans, the loan yield and the types and amount of funding sources. The Company may also retain mortgage loan production in order to improve yields and increase balance sheet leverage. In addition, management periodically considers the sale of commercial and other loans as part of its management of credit risk. Loans held for sale are carried at the lower of unpaid principal balance, net, or estimated fair value on an aggregate basis. Estimated fair value is determined based on bid quotations from securities dealers.
Allowance for Loan Losses	Allowance for Loan Losses The allowance for loan losses is a valuation account that reflects probable incurred losses in the loan portfolio. The adequacy of the allowance for loan losses is based on management’s evaluation of the Bank’s past loan loss experience, known and inherent risks in the portfolio, adverse situations that may affect the borrower’s ability to repay, estimated value of any underlying collateral, current economic and regulatory conditions, as well as organizational changes. Additions to the allowance arise from charges to operations through the provision for loan losses or from the recovery of amounts previously charged-off. The allowance is reduced by loan charge-offs. The allowance for loan losses is maintained at an amount management considers sufficient to provide for probable losses. A cquired loans are marked to fair value on the date of acquisition and are evaluated on a quarterly basis to ensure the necessary purchase accounting updates are made in parallel with the allowance for loan loss calculation. Acquired loans that have been renewed since acquisition are included in the allowance for loan loss calculation since these loans have been underwritten to the Bank’s guidelines. Acquired loans that have not been renewed since acquisition, or that have a PCI mark, are excluded from the allowance for loan loss calculation. The Bank calculates a general valuation allowance for these excluded acquired loans without a PCI mark and compares that to the remaining general credit and interest rate marks. To the extent the remaining general credit and interest rate marks exceed the calculated general valuation allowance, no additional reserve is required. If the calculated general valuation allowance exceeds the remaining general credit and interest rate marks, the Bank would record an adjustment to the extent necessary. The Bank’s allowance for loan losses includes specific allowances and a general allowance, each updated on a quarterly basis. A specific allowance is determined for all impaired loans (excluding PCI loans). The Bank defines an impaired loan as all non-accrual commercial real estate, multi-family, land, construction and commercial loans in excess of $250,000 for which it is probable, based on current information, that the Company 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. For collateral dependent loans, the specific allowance represents the difference between the Bank’s recorded investment in the loan, net of any interim charge-offs, and the estimated fair value of the collateral, less estimated selling costs. Impairment for all other impaired loans is calculated based on a combination of the estimated fair value of non-real estate collateral, personal guarantees, or the present value of the expected future cash flows. Generally, for collateral dependent real estate loans, the Bank obtains an updated collateral appraisal once the loan is impaired. For impaired residential real estate loans, the appraisal is generally updated annually if the loan remains delinquent for an extended period. For impaired commercial real estate loans, the Bank assesses whether there has likely been an adverse change in the collateral value supporting the loan. The Bank utilizes information based on its knowledge of changes in real estate conditions in its lending area to identify whether a possible deterioration of collateral value has occurred. Based on the severity of the changes in market conditions, management determines if an updated commercial real estate appraisal is warranted or if downward adjustments to the previous appraisal are warranted. If it is determined that the deterioration of the collateral value is significant enough to warrant ordering a new appraisal, an estimate of the downward adjustments to the existing appraised value is used in assessing if additional specific reserves are necessary until the updated appraisal is received. A general allowance is determined for all loans that are not individually evaluated for impairment (excluding acquired loans that have not been renewed under the Bank’s underwriting criteria). In determining the level of the general allowance, the Bank segments the loan portfolio into the following portfolio segments: residential real estate; consumer; investor-owned commercial real estate; owner-occupied commercial real estate; construction and land; and commercial and industrial. The portfolio segments are further segmented by delinquency status or risk rating. An estimated loss factor is then applied to the outstanding principal loan balance of the delinquency status or risk rating category for each portfolio segment. To determine the loss factor, the Bank utilizes historical loss experience adjusted for certain qualitative factors and the loss emergence period. The Bank’s historical loss experience is based on a rolling 36 -month look-back period for each portfolio segment. The look-back period was selected based on (1) management’s judgment that this period captures sufficient loss events (in both dollar terms and number of individual events) to be relevant; and (2) that the Bank’s underwriting criteria and risk characteristics have remained relatively stable throughout this period. The historical loss experience is adjusted for certain qualitative factors including, but not limited to, (1) delinquency trends, (2) net charge-off trends, (3) nature and volume of the loan portfolio, (4) loan policies and underwriting standards, (5) experience and ability of lending personnel, (6) concentrations of credit, (7) loan review system, and external factors such as (8) changes in current economic conditions, (9) local competition and (10) regulation. Economic factors that the Bank considers in its estimate of the allowance for loan losses include: local and regional trends in economic growth, unemployment and real estate values. The Bank considers the applicability of each of these qualitative factors in estimating the general allowance for each portfolio segment. Each quarter, the Bank considers the current conditions for each of the qualitative factors, as well as a forward looking view on trends and events, to support an assessment unique to each portfolio segment. The Bank calculates and analyzes the loss emergence period on an annual basis or more frequently if conditions warrant. The Bank’s methodology is to use loss events in the past 12 quarters to determine the loss emergence period for each loan segment. The loss emergence period is specific to each portfolio segment. It represents the amount of time that has elapsed between (1) the occurrence of a loss event, which resulted in a potential loss and (2) the confirmation of the potential loss, when the Bank records an initial charge-off or downgrades the risk-rating of the loan to substandard. The Bank also maintains an unallocated portion of the allowance for loan losses. The primary purpose of the unallocated component is to account for the inherent factors that cannot be practically assigned to individual loss categories, including the periodic update of appraisals, subjectivity of the Bank’s credit review and risk rating process, and economic conditions that may not be fully captured in the Bank’s loss history or qualitative factors. Upon completion of the aforementioned procedures, an overall management review is performed including ratio analyses to identify divergent trends compared with the Bank’s own historical loss experience, the historical loss experience of the Bank’s peer group and management’s understanding of general regulatory expectations. Based on that review, management may identify issues or factors that previously had not been considered in the estimation process, which may warrant further analysis or adjustments to estimated loss or qualitative factors applied in the calculation of the allowance for loan losses.
Reserve for Repurchased Loans and Loss Sharing Obligations	Reserve for Repurchased Loans and Loss Sharing Obligations The reserve for repurchased loans and loss sharing obligations relates to potential losses on loans sold which may have to be repurchased due to a violation of representations and warranties and an estimate of the Bank’s obligation under a loss sharing arrangement for loans sold to the Federal Home Loan Bank (“FHLB”) as well as the potential repair requests for guaranteed loans sold to the Small Business Administration (“SBA”). Provisions for losses are charged to gain on sale of loans and credited to the reserve while actual losses are charged to the reserve. The reserve represents the Company’s estimate of the total losses expected to occur and is considered to be adequate by management based upon the Company’s evaluation of the potential exposure related to the loan sale agreements over the period of repurchase risk. The reserve for repurchased loans and loss sharing obligations is included in other liabilities on the Company’s consolidated statement of financial condition as well as SBA repair requests.
Other Real Estate Owned	Other Real Estate Owned Other real estate owned (“OREO”) is carried at the lower of cost or estimated fair value, less estimated costs to sell. When a property is acquired, the excess of the loan balance over estimated fair value is charged to the allowance for loan losses. Operating results from other real estate owned, including rental income, operating expenses, gains and losses realized from the sales of other real estate owned and subsequent write-downs are recorded as incurred.
Premises and Equipment	Premises and Equipment Land is carried at cost and premises and equipment, including leasehold improvements, are stated at cost less accumulated depreciation and amortization or, in the case of acquired premises, the value on the acquisition date. Depreciation and amortization are computed using the straight-line method over the estimated useful lives of the assets or leases. Generally, depreciable lives are as follows: computer equipment: 3 years ; furniture, fixtures and other electronic equipment: 5 years ; building improvements: 10 years ; and buildings: 30 years . Repair and maintenance items are expensed and improvements are capitalized. Gains and losses on dispositions are reflected in current operations.
Income Taxes	Income Taxes The Company utilizes the asset and liability method of accounting for income taxes. Under this method, deferred tax assets and liabilities are recognized for the 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 expected to apply to taxable income in the years 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. Any interest and penalties on taxes payable are included as part of the provision for income taxes.
Comprehensive Income	Comprehensive Income Comprehensive income is comprised of net income and other comprehensive income. Other comprehensive income includes items recorded directly in equity, such as unrealized gains or losses on debt securities available-for-sale and accretion of unrealized loss on debt securities reclassified to held-to-maturity.
Bank Owned Life Insurance	Bank Owned Life Insurance Bank Owned Life Insurance (“BOLI”) is accounted for using the cash surrender value method and is recorded at its realizable value. Part of the Company’s BOLI is invested in a separate account insurance product which is invested in a fixed income portfolio. The separate account includes stable value protection which maintains realizable value at book value with investment gains and losses amortized over future periods. Increases in cash surrender value are included in other non-interest income, while proceeds from death benefits are generally recorded as a reduction to the carrying value.
Intangible Assets	Intangible Assets Intangible assets resulting from acquisitions under the acquisition method of accounting consist of goodwill and core deposit intangible. Goodwill represents the excess of the purchase price over the estimated fair value of identifiable net assets acquired through purchase acquisitions. 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. 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 August 31, 2019 . Based upon its qualitative assessment of goodwill, the Company concluded that goodwill was not impaired and no further quantitative analysis was warranted.
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 throughout New Jersey and the metropolitan areas of Philadelphia and New York City . 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 net income available to common stockholders by the weighted average number of shares of common stock outstanding. Diluted earnings per share is calculated by dividing net income available to common stockholders by the weighted average number of shares of common stock outstanding plus potential common stock, utilizing the treasury stock method. All share amounts exclude unallocated shares of stock held by the Employee Stock Ownership Plan (“ESOP”) and the 2006 and 2011 Incentive Plans (refer to Note 12 Incentive Plan, for further discussion).
Impact of New Accounting Pronouncements	Impact of New Accounting Pronouncements Accounting Pronouncements Adopted in 2019 In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842).” This ASU requires all lessees to recognize a lease liability and a right-of-use asset, measured at the present value of the future minimum lease payments, at the lease commencement date. Lessor accounting remains largely unchanged under the new guidance. The guidance is effective for fiscal years beginning after December 15, 2018, including interim reporting periods within that reporting period, with early adoption permitted. A modified retrospective approach may be applied for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements On July 30, 2018, the FASB issued ASU 2018-11, “Leases (Topic 842) Targeted Improvements”, which provided an option to apply the transition provisions of the new standard at the adoption date rather than the earliest comparative period presented. Additionally, the ASU provides a practical expedient permitting lessors to not separate non-lease components from the associated lease component if certain conditions are met. The Company adopted this ASU in its entirety on January 1, 2019, and has appropriately reflected the changes throughout the Company’s consolidated financial statements. The Company elected to apply the new standard as of the adoption date and will not restate comparative prior periods. Additionally, the Company elected to apply the package of practical expedients standard under which the Company need not reassess whether any expired or existing contracts are leases or contain leases, the Company need not reassess the lease classification for any expired or existing lease, and the Company need not reassess initial direct costs for any existing leases. The adoption of this ASU resulted in the recognition of a right-of-use asset of $20.6 million in other assets and a lease liability of $20.7 million in other liabilities. Refer to Note 17 Leases, for additional information. In March 2017, the FASB issued ASU 2017-08, “Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20) - Premium Amortization on Purchased Callable Debt Securities.” This ASU requires the amortization of premiums to the earliest call date on debt securities with call features that are explicit, noncontingent and callable at fixed prices and on preset dates. This ASU does not impact securities held as a discount, as the discount continues to be amortized to the contractual maturity. The guidance is effective for fiscal years beginning after December 15, 2018, with early adoption permitted, including adoption in an interim period. The amendments in this ASU should be applied on a modified retrospective basis through a cumulative-effect adjustment directly to retained earnings as of the beginning of the period of adoption. The adoption of this update did not have an impact on the Company’s consolidated financial statements. In August 2017, the FASB issued ASU 2017-12, “Derivatives and Hedging (Topic 815) - Targeted Improvements to Accounting for Hedging Activities.” The amendments in this ASU was issued to better align an entity’s risk management activities and financial reporting for hedging relationships through changes to both the designation and measurement guidance for qualifying hedging relationships and the presentation of hedge results. As a result, the amendments expand and refine hedge accounting for both nonfinancial and financial risk components and align the recognition and presentation of the effects of the hedging instrument and the hedged item in the financial statements. Current GAAP contains limitations on how an entity can designate the hedged risk in certain cash flow and fair value hedging relationships. To address those current limitations, the amendments in this ASU permit hedge accounting for risk components in hedging relationships involving nonfinancial risk and interest rate risk. In addition, the amendments in this ASU change the guidance for designating fair value hedges of interest rate risk and for measuring the change in fair value of the hedged item in fair value hedges of interest rate risk. The amendments in this ASU are effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Early adoption was permitted. The Company does not enter into derivatives that are designated as hedging instruments and as such, the adoption of this ASU did not have an impact on the Company’s consolidated financial statements. In February 2018, the FASB issued ASU 2018-02, “Income Statement - Reporting Comprehensive Income (Topic 220) - Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income.” This ASU was issued to address a narrow-scope financial reporting issue that arose as a result of the enactment of the Tax Cuts and Jobs Act (“Tax Reform”) on December 22, 2017. The objective of ASU 2018-02 is to address the tax effects of items within accumulated other comprehensive income (referred to as “stranded tax effects”) that do not reflect the appropriate tax rate enacted in the Tax Reform. As a result, the ASU 2018-02 allows a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the newly enacted federal corporate income tax rate. The amount of the reclassification would be the difference between the historical corporate income tax rate of 35 percent and the newly enacted corporate income tax rate of 21 percent. ASU 2018-02 is effective for fiscal years beginning after December 15, 2018, with early adoption permitted, including adoption in an interim period. The amendments in this ASU may be applied retrospectively to each period in which the effect of the change in the U.S. Federal corporate income tax rate in the Tax Reform is recognized. The Company has early adopted ASU 2018-02 for the year ended December 31, 2017, and has elected not to reclassify the income tax effects of the Tax Reform from accumulated other comprehensive loss to retained earnings. Accounting Pronouncements Not Yet Adopted In June 2016, the FASB issued ASU 2016-13, “Measurement of Credit Losses on Financial Instruments.” This ASU significantly changed how entities will measure credit losses for financial assets and certain other instruments that are measured at amortized cost. The standard replaced today’s “incurred loss” approach with an “expected loss” model, which necessitates a forecast of lifetime losses. The new model, referred to as the current expected credit loss (“CECL”) model, applies to: (1) financial assets subject to credit losses and measured at amortized cost, and (2) certain off-balance sheet credit exposures. This includes, but is not limited to, loans, leases, held-to-maturity securities, loan commitments, and financial guarantees. The CECL model does not apply to available-for-sale (“AFS”) debt securities. The ASU simplifies the accounting model for purchased credit-impaired debt securities and loans. ASU No. 2016-13 is effective for interim and annual reporting periods beginning after December 15, 2019; early adoption is permitted for interim and annual reporting periods beginning after December 15, 2018. Entities will apply the standard’s provisions as a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective (i.e., modified retrospective approach). The Company will utilize the modified retrospective approach. The Company’s CECL implementation efforts are in process and continue to focus on model validation, developing new disclosures, establishing formal policies and procedures and other governance and control documentation. Certain elements of the calculation are pending finalization, including refinement of the model assumptions, the qualitative framework, internal control design, model validation, and the operational control framework to support the new process. Furthermore, changes to the economic forecasts within the model could positively or negatively impact the actual results. Due to these items, the quantitative impact to the consolidated financial statements cannot yet be reasonably estimated. In January 2017, the FASB issued ASU 2017-04, “Intangibles - Goodwill and Other (Topic 350) - Simplifying the Test for Goodwill Impairment.” This ASU intends to simplify the subsequent measurement of goodwill, eliminating Step 2 from the goodwill impairment test. Instead, an entity should perform its annual goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity should recognize an impairment charge by which the carrying amount exceeds the reporting unit’s fair value; however the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. The ASU also eliminates the requirement for any reporting unit with a zero or negative carrying amount to perform a qualitative assessment. ASU No. 2017-04 is effective for fiscal years beginning after December 15, 2019; early adoption is permitted for annual goodwill impairment tests performed on testing dates after January 1, 2017. The adoption of this update will not have a material impact on the Company’s consolidated financial statements. In August 2018, the FASB issued ASU 2018-13, “Fair Value Measurement (Topic 820) - Changes to the Disclosure Requirements for Fair Value Measurement.” This ASU updates the disclosure requirements on Fair Value measurements by 1) removing: the disclosures for transfers between Level 1 and Level 2 of the fair value hierarchy, the policy for timing of transfers between levels, and the valuation processes for Level 3 fair value measurements; 2) modifying: disclosures for timing of liquidation of an investee’s assets and disclosures for uncertainty in measurement as of reporting date; and 3) adding: disclosures for changes in unrealized gains and losses included in other comprehensive income for recurring level 3 fair value measurements and disclosures for the range and weighted average of the significant unobservable inputs used to develop Level 3 fair value measurements. ASU 2018-13 is effective for fiscal years beginning after December 15, 2019, with early adoption permitted to any removed or modified disclosures and delay adoption of additional disclosures until the effective date. With the exception of the following, which should be applied prospectively, disclosures relating to changes in unrealized gains and losses, the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements, and the disclosures for uncertainty measurement, all other changes should be applied retrospectively to all periods presented upon the effective date. The adoption of this update will not have a material impact on the Company’s consolidated financial statements.
