Basis of Presentation	Basis of Presentation The consolidated financial statements include the accounts of OceanFirst Financial Corp. (the “Company”) and its wholly-owned subsidiaries, OceanFirst Bank N.A.

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. The interim consolidated financial statements reflect all normal and recurring adjustments which are, in the opinion of management, considered necessary for a fair presentation of the financial condition and results of operations for the periods presented. The results of operations for the three months ended March 31, 2019 are not necessarily indicative of the results of operations that may be expected for all of 2019 . In preparing the consolidated financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the statements of financial condition and the results of operations for the period. Actual results could differ from these estimates. Certain information and note disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles have been condensed or omitted, pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”). These unaudited consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018 .

Business Combinations [Abstract]
Business Combinations	Business Combinations Sun Bancorp, Inc. Acquisition On January 31, 2018, the Company completed its acquisition of Sun Bancorp, Inc. (“Sun”), which after purchase accounting adjustments added $2.0 billion to assets, $1.5 billion to loans, and $1.6 billion to deposits. Total consideration paid for Sun was $474.9 million , including cash consideration of $72.4 million . Sun was merged with and into the Company on the date of acquisition. The acquisition was accounted for under the acquisition method of accounting. Under this method of accounting, the purchase price has been allocated to the respective assets acquired and liabilities assumed based upon their estimated fair values, net of tax. The excess of consideration paid over the estimated fair value of the net assets acquired has been recorded as goodwill. The following table summarizes the estimated fair values of the assets acquired and the liabilities assumed at the date of the acquisition for Sun, net of the total consideration paid (in thousands): At January 31, 2018 Fair Value Total Purchase Price: $ 474,930 Assets acquired: Cash and cash equivalents $ 68,632 Securities 254,522 Loans 1,517,345 Accrued interest receivable 5,621 Bank Owned Life Insurance 85,238 Deferred tax asset 57,597 Other assets 43,202 Core deposit intangible 11,897 Total assets acquired 2,044,054 Liabilities assumed: Deposits (1,616,073 ) Borrowings (127,727 ) Other liabilities (13,242 ) Total liabilities assumed (1,757,042 ) Net assets acquired $ 287,012 Goodwill recorded in the merger $ 187,918 The calculation of goodwill is subject to change for up to one year after the date of acquisition as additional information relative to the closing date estimates and uncertainties become available. On January 31, 2019, the Company finalized its review of the acquired assets and liabilities and will not be recording any further adjustments to the carrying value. Capital Bank of New Jersey Acquisition On January 31, 2019, the Company completed its acquisition of Capital Bank of New Jersey (“Capital Bank”), which after purchase accounting adjustments added $494.2 million to assets, $307.0 million to loans, and $449.0 million to deposits. Total consideration paid for Capital Bank was $76.8 million , including cash consideration of $353,000 . Capital Bank was merged with and into the Company on the date of acquisition. The acquisition was accounted for under the acquisition method of accounting. Under this method of accounting, the purchase price has been allocated to the respective assets acquired and liabilities assumed based upon their estimated fair values, net of tax. The excess of consideration paid over the estimated fair value of the net assets acquired has been recorded as goodwill. The following table summarizes the estimated fair values of the assets acquired and the liabilities assumed at the date of the acquisition for Capital Bank, net of total consideration paid (in thousands): At January 31, 2019 Capital Bank Book Value Purchase Estimated Total Purchase Price: $ 76,834 Assets acquired: Cash and cash equivalents $ 59,748 $ — $ 59,748 Securities 103,798 (23 ) 103,775 Loans 312,320 (5,303 ) 307,017 Accrued interest receivable 1,387 — 1,387 Bank Owned Life Insurance 10,460 — 10,460 Deferred tax asset 1,605 2,373 3,978 Other assets 9,384 (4,185 ) 5,199 Core deposit intangible — 2,662 2,662 Total assets acquired 498,702 (4,476 ) 494,226 Liabilities assumed: Deposits (448,792 ) (226 ) (449,018 ) Other liabilities (827 ) (4,224 ) (5,051 ) Total liabilities assumed (449,619 ) (4,450 ) (454,069 ) Net assets acquired $ 49,083 $ (8,926 ) $ 40,157 Goodwill recorded in the merger $ 36,677 The calculation of goodwill is subject to change for up to one year after the date of acquisition as additional information relative to the closing date estimates and uncertainties become available. As the Company finalizes its review of the acquired assets and liabilities, certain adjustments to the recorded carrying values may be required. Supplemental Pro Forma Financial Information The following table presents financial information regarding the former Capital Bank operations included in the Consolidated Statements of Income from the date of the acquisition (January 31, 2019) through March 31, 2019 . In addition, the table provides unaudited condensed pro forma financial information assuming the Capital Bank acquisition had been completed as of January 1, 2019 for the three months ended March 31, 2019 and as of January 1, 2018 for the three months ended March 31, 2018. The table below has been prepared for comparative purposes only and is not necessarily indicative of the actual results that would have been attained had the acquisition occurred as of the beginning of the periods presented, nor is it indicative of future results. Furthermore, the unaudited pro forma information does not reflect management’s estimate of any revenue-enhancing opportunities nor anticipated cost savings or the impact of conforming certain accounting policies of the acquired company to the Company’s policies that may have occurred as a result of the integration and consolidation of Capital Bank’s operations. The pro forma information shown reflects adjustments related to certain purchase accounting fair value adjustments; amortization of core deposit and other intangibles; and related income tax effects.

Refer to Note 8, 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 21 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. Borrowings Fair value estimates are based on discounting contractual cash flows using rates which approximate the rates offered for borrowings of similar remaining maturities.

The Company concluded that these corporate debt securities were only temporarily impaired at March 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 March 31, 2019 .

At March 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 homogenous 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 March 31, 2019 and December 31, 2018 , and based on the most recent analysis performed, the risk category of loans by loan portfolio segment follows, excluding PCI loans (in thousands) is as follows: Pass Special Mention Substandard Doubtful Total March 31, 2019 Commercial and industrial $ 369,701 $ 4,589 $ 6,057 $ — $ 380,347 Commercial real estate – owner occupied 775,723 6,514 19,053 — 801,290 Commercial real estate – investor 2,103,459 22,542 23,890 — 2,149,891 $ 3,248,883 $ 33,645 $ 49,000 $ — $ 3,331,528 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 loan classes, 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 March 31, 2019 and December 31, 2018 , excluding PCI loans (in thousands): Residential Consumer March 31, 2019 Performing $ 2,153,711 $ 464,655 Non-performing 8,611 3,364 $ 2,162,322 $ 468,019 December 31, 2018 Performing $ 2,036,897 $ 472,033 Non-performing 7,389 2,914 $ 2,044,286 $ 474,947 The recorded investment in mortgage and consumer loans collateralized by residential real estate, which are in the process of foreclosure, amounted to $2.1 million at March 31, 2019 . The amount of foreclosed residential real estate property held by the Company was $841,000 at March 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 March 31, 2019 , and December 31, 2018 , were $6.5 million and $3.6 million , respectively, of troubled debt restructurings. At March 31, 2019 , and December 31, 2018 , the Company had $487,000 and $0 , respectively, of specific reserves allocated to loans that are 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 restructurings at March 31, 2019 and December 31, 2018 , which totaled $19.7 million and $22.9 million , respectively. Troubled debt restructurings are considered in the allowance for loan losses similar to other impaired loans. The following table presents information about troubled debt restructurings which occurred during the three months ended March 31, 2019 and 2018 , and troubled debt restructurings modified within the previous year and which defaulted during the three months ended March 31, 2019 and 2018 (dollars in thousands): Number of Loans Pre-modification Recorded Investment Post-modification Recorded Investment Three months ended March 31, 2019 Troubled Debt Restructurings: Residential real estate 3 589 621 Number of Loans Recorded Investment Troubled Debt Restructurings Which Subsequently Defaulted: None None Number of Loans Pre-modification Recorded Investment Post-modification Recorded Investment Three Months Ended March 31, 2018 Troubled Debt Restructurings: Commercial and industrial 1 $ 237 $ 243 Commercial real estate – investor 1 179 180 Residential real estate 2 257 270 Number of Loans Recorded Investment Troubled Debt Restructurings Which Subsequently Defaulted: None None As part of the Capital Bank acquisition, PCI loans were acquired at a discount primarily due to deteriorated credit quality. PCI loans are accounted for at fair value, based upon the present value of expected future cash flows, with no related allowance for loan losses.

Accounting Changes and Error Corrections [Abstract]
Recent Accounting Pronouncements	Recent Accounting Pronouncements 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 10, Leases, for additional information. In June 2016, the FASB issued ASU 2016-13, “Measurement of Credit Losses on Financial Instruments.” This ASU significantly changes how entities will measure credit losses for most financial assets and certain other instruments that aren’t measured at fair value through net income. The standard will replace today’s “incurred loss” approach with an “expected loss” model. The new model, referred to as the current expected credit loss (“CECL”) model, will apply 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. For AFS debt securities with unrealized losses, entities will measure credit losses in a manner similar to what they do today, except that the losses will be recognized as allowances rather than reductions in the amortized cost of the securities. As a result, entities will recognize improvements to estimated credit losses immediately in earnings rather than as interest income over time, as they do today. The ASU also simplifies the accounting model for purchased credit-impaired debt securities and loans. ASU 2016-13 also expands the disclosure requirements regarding an entity’s assumptions, models, and methods for estimating the allowance for loan and lease losses. In addition, entities will need to disclose the amortized cost balance for each class of financial asset by credit quality indicator, disaggregated by the year of origination. 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 has begun its evaluation of the amended guidance including the potential impact on its consolidated financial statements. As a result of the required change in approach toward determining estimated credit losses from the current “incurred loss” model to one based on estimated cash flows over a loan’s contractual life, adjusted for prepayments (a “life of loan” model), the Company expects that the new guidance may result in an increase in the allowance for loan losses, particularly for longer duration loan portfolios. The Company also expects that the new guidance may result in an allowance for debt securities. In both cases, the extent of the change is indeterminable at this time as it will be dependent upon portfolio composition and credit quality at the adoption date, as well as economic conditions and forecasts at that time. 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 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. 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.

Fair Value Measurements

Fair Value Measurements	3 Months Ended

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 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 three months ended March 31, 2019 . 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 Securities 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 security 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 March 31, 2019 and December 31, 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 March 31, 2019 Items measured on a recurring basis: Debt securities available-for-sale $ 122,558 $ — $ 122,558 $ — Equity investments 9,816 9,816 — — Interest rate swap asset 2,902 — 2,902 — Interest rate swap liability (3,047 ) — (3,047 ) — Items measured on a non-recurring basis: Other real estate owned 1,594 — — 1,594 Loans measured for impairment based on the fair value of the underlying collateral 9,199 — — 9,199 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 1, Level 2 and, infrequently, Level 3 inputs. In general, fair value is based upon quoted market prices, where available. Most of the Company’s investment and mortgage-backed securities, however, 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 mortgage, 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 March 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 March 31, 2019 Financial Assets: Cash and due from banks $ 134,235 $ 134,235 $ — $ — Debt securities held-to-maturity 900,614 — 888,177 8,635 Restricted equity investments 55,663 — — 55,663 Loans receivable, net and loans held-for-sale 5,968,830 — — 5,893,831 Financial Liabilities: Deposits other than time deposits 5,340,892 — 5,340,892 — Time deposits 949,593 — 941,672 — Federal Home Loan Bank advances and other borrowings 517,595 — 525,476 — Securities sold under agreements to repurchase with retail customers 66,174 66,174 — — 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. The Company recognized losses of $54,000 and $2,000 in other income resulting from fair value adjustments during the quarters ended March 31, 2019 , and March 31, 2018 , respectively. The table below presents the notional and fair value of derivatives not designated as hedging instruments as well as their location on the consolidated statements of financial condition as of March 31, 2019 (in thousands): March 31, 2019 December 31, 2018 Balance Sheet Location Notional Fair Value Notional Fair Value Other assets $ 81,205 $ 2,902 $ 59,305 $ 1,722 Other liabilities 81,205 3,047 59,305 1,813 Credit risk-related Contingent Features The Company is a party to an International Swaps and Derivatives Association agreement 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 $4.9 million , and $4.1 million at March 31, 2019 , and December 31, 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 $3.0 million and $1.8 million at March 31, 2019 , and December 31, 2018 , respectively .

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 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”) and a corresponding lease liability. The Company had two existing finance leases (previously referred to as capital leases), which were acquired in the Sun acquisition and have lease terms through 2029. These leases were 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 these leases. The following table represents the classification of the Company’s ROU assets and lease liabilities on the consolidated statements of financial condition (in thousands): March 31, 2019 Lease ROU Assets Classification Operating lease ROU asset Other Assets $ 20,617 Finance lease ROU asset Premises and equipment, net 3,388 Total Lease ROU Asset $ 24,005 Lease Liabilities Operating lease liability Other Liabilities $ 20,651 Finance lease liability Other Borrowings 5,269 Total Lease Liability $ 25,920 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, 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 leases, the Company utilized its incremental borrowing rate at lease inception.

Accounting Changes and Error Corrections [Abstract]
Recent Accounting Pronouncements	Recent Accounting Pronouncements 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 10, Leases, for additional information. In June 2016, the FASB issued ASU 2016-13, “Measurement of Credit Losses on Financial Instruments.” This ASU significantly changes how entities will measure credit losses for most financial assets and certain other instruments that aren’t measured at fair value through net income. The standard will replace today’s “incurred loss” approach with an “expected loss” model. The new model, referred to as the current expected credit loss (“CECL”) model, will apply 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. For AFS debt securities with unrealized losses, entities will measure credit losses in a manner similar to what they do today, except that the losses will be recognized as allowances rather than reductions in the amortized cost of the securities. As a result, entities will recognize improvements to estimated credit losses immediately in earnings rather than as interest income over time, as they do today. The ASU also simplifies the accounting model for purchased credit-impaired debt securities and loans. ASU 2016-13 also expands the disclosure requirements regarding an entity’s assumptions, models, and methods for estimating the allowance for loan and lease losses. In addition, entities will need to disclose the amortized cost balance for each class of financial asset by credit quality indicator, disaggregated by the year of origination. 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 has begun its evaluation of the amended guidance including the potential impact on its consolidated financial statements. As a result of the required change in approach toward determining estimated credit losses from the current “incurred loss” model to one based on estimated cash flows over a loan’s contractual life, adjusted for prepayments (a “life of loan” model), the Company expects that the new guidance may result in an increase in the allowance for loan losses, particularly for longer duration loan portfolios. The Company also expects that the new guidance may result in an allowance for debt securities. In both cases, the extent of the change is indeterminable at this time as it will be dependent upon portfolio composition and credit quality at the adoption date, as well as economic conditions and forecasts at that time. 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 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. 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.
