Organization, Consolidation and Presentation of Financial Statements [Abstract]
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. (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 Hooper Holdings, LLC., TRREO Holdings LLC, Casaba Real Estate Holdings Corporation, Cohensey Bridge, L.L.C., Prosperis Financial, LLC, CBNJ Investments Corp., Country Property Holdings, Inc., and TRCB Investment Corp. All significant intercompany accounts and transactions have been eliminated in consolidation. 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 and nine months ended September 30, 2020 are not necessarily indicative of the results of operations that may be expected for the full year 2020. 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, 2019. Recently Adopted Accounting Pronouncements In June 2016, the FASB issued ASU 2016-13, “Measurement of Credit Losses on Financial Instruments (Topic 326).” This ASU significantly changed how entities measure credit losses for financial assets and certain other instruments that are measured at amortized cost. The standard replaced the “incurred loss” approach with an “expected loss” model, which necessitates a forecast of lifetime losses. The new model, referred to as the 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. The standard’s provisions are to be applied 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 adopted ASU 2016-13 As allowed by ASC 326, the Company elected not to maintain pools of loans accounted for under ASC 310-30. At December 31, 2019, purchase credit impaired (“PCI”) loans totaled $13.3 million. In accordance with the standard, management did not reassess whether modifications individually acquired financial assets accounted for in pools were troubled debt restructured loans as of the date of adoption. Upon adoption, the Company’s PCI loans were converted to PCD loans as defined by ASC 326. The transition adjustment for the PCI loans to PCD loans resulted in a reclassification of $3.2 million from the specific credit fair value adjustment to the allowance for credit losses on loans. Management estimates the allowance balance using relevant available information, from internal and external sources, relating to past events, current conditions, and reasonable and supportable forecasts. Historical credit loss experience provides the basis for the estimation of expected credit losses. Adjustments to historical loss information are made for differences in current loan-specific risk characteristics such as differences in underwriting standards, portfolio mix, delinquency level, or term as well as changes in environmental conditions, such as changes in unemployment rates, property values, or other relevant factors. At September 30, 2020, the Company utilized the September 15, 2020 forecast, from Oxford Economics, the most recent forecast available as of quarter end, to provide the macroeconomic forecasts for select variables. Expected credit losses are estimated over the contractual term of the loans, adjusted for expected prepayments when appropriate. The contractual term excludes expected extensions, renewals, and modifications. 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. The adoption of this update did not have an 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 did not have an impact on the Company’s consolidated financial statements. Refer to Note 7 Fair Value Measurements, for additional information.

Supplemental Pro Forma Financial Information The following table presents financial information regarding the former Two River and Country Bank operations included in the Consolidated Statements of Income from the date of the acquisition (January 1, 2020) through September 30, 2020. The table also 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 September 30, 2020. In addition, the table provides unaudited condensed pro forma financial information assuming the Two River, Country Bank, and Capital Bank acquisitions had been completed as of January 1, 2019 for the nine months ended September 30, 2019. 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 Two River, Country Bank, and 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 7, 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 or historical loss experiences of peer groups where deemed appropriate. 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, subsequent to January 1, 2020, the Company identified loans that have experienced more-than-insignificant deterioration in credit quality since origination. Loans meeting this 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, Capital Bank, Two River and Country Bank operated one, 14, and five properties, respectively, subject to lease agreements. 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 $2.7 million, $12.1 million, and $2.1 million, for the acquisitions of Capital Bank, Two River, and Country 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 September 30, 2020. 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. Additionally, there are private label commercial mortgage-backed securities with credit ratings from multiple credit rating services ranging between Aaa and Aa2. The Company considers the unrealized losses to be the result of changes in interest rates, and not credit quality, 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 September 30, 2020. The Company monitors the credit quality of debt securities held-to-maturity on a quarterly basis through the use of credit ratings. The following table summarized the amortized cost of debt securities held-to-maturity at September 30, 2020, aggregated by credit quality indicator (in thousands): AAA AA A BBB BB Total As of September 30, 2020 Investment securities: U.S. government and agency obligations $ — $ 4,997 $ — $ — $ — $ 4,997 State and municipal obligations 35,280 128,128 46,390 5,067 — 214,865 Corporate debt securities — 1,495 11,960 47,502 11,332 72,289 Total investment securities 35,280 134,620 58,350 52,569 11,332 292,151 Mortgage-backed securities: CMO 16,909 32,836 — — — 49,745 Total mortgage-backed securities 16,909 32,836 — — — 49,745 Total debt securities held-to-maturity $ 52,189 $ 167,456 $ 58,350 $ 52,569 $ 11,332 $ 341,896 A debt security is considered to be past due once it is 30 days past due under the terms of the agreement.

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. This includes borrowers that have been negatively affected by the pandemic but demonstrate some degree of liquidity. This liquidity may or may not be adequate to resume operations. 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. This includes borrowers whose operations were negatively affected by the pandemic and whom, in our assessment, do not have adequate liquidity available to resume operations at levels sufficient to service their current debt levels. 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.

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. At September 30, 2020 and December 31, 2019, troubled debt restructured (“TDR”) loans totaled $22.6 million and $24.6 million, respectively. Included in the non-accrual loan total at September 30, 2020, and December 31, 2019, were $9.9 million and $6.6 million, respectively, of troubled debt restructurings. At September 30, 2020, and December 31, 2019, the Company had $448,000 and $476,000, 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 September 30, 2020 and December 31, 2019, which totaled $12.8 million and $18.0 million, respectively. The following table presents information about troubled debt restructurings which occurred during the three and nine months ended September 30, 2020 and September 30, 2019, and troubled debt restructurings modified within the previous year and which defaulted during the three and nine months ended September 30, 2020 and September 30, 2019 (dollars in thousands): Number of Loans Pre-modification Post-modification Three months ended September 30, 2020 Troubled Debt Restructurings: Consumer 1 $ 16 $ 16 Commercial real estate – investor 1 928 993 Residential real estate 1 418 418 Number of Loans Recorded Investment Troubled Debt Restructurings Which Subsequently Defaulted: None None Number of Loans Pre-modification Post-modification Nine months ended September 30, 2020 Troubled Debt Restructurings: Consumer 5 $ 175 $ 193 Commercial real estate – owner occupied 1 1,112 1,143 Commercial real estate – investor 1 928 993 Residential real estate 5 849 865 Number of Loans Recorded Investment Troubled Debt Restructurings Which Subsequently Defaulted: None None Number of Loans Pre-modification Post-modification Three Months Ended September 30, 2019 Troubled Debt Restructurings: Consumer 1 $ 54 $ 54 Number of Loans Recorded Investment Troubled Debt Restructurings Which Subsequently Defaulted None None Number of Loans Pre-modification Post-modification Nine months ended September 30, 2019 Troubled Debt Restructurings: Consumer 5 $ 496 $ 516 Residential real estate 5 921 972 Number of Loans Recorded Investment Troubled Debt Restructurings Which Subsequently Defaulted: None None In response to the COVID-19 pandemic and its economic impact on customers, short-term modification programs that comply with the CARES Act were implemented to provide temporary payment relief to those borrowers directly impacted by COVID-19. The Commercial Borrower Relief Program allowed for the deferral of principal and interest or principal only. For principal and interest deferrals as well as principal only deferrals, all payments received will first be applied to all accrued and unpaid interest and the balance, if any, on account of unpaid principal, then to fees, expenses and other amounts due to the Bank. Monthly payments shall continue until the maturity date when all then unpaid principal, interest, fees, and all other charges are due and payable to the Bank. The Consumer Borrower Relief Program allowed for the deferral of principal and interest. The deferred payments along with interest accrued during the deferral period are due and payable on the maturity date. Provided these loans were current as of either year end or the date of the modification, these loans are not considered TDR loans at September 30, 2020 and will not be reported as past due during the deferral period. As part of the Two River and Country Bank acquisitions, the Company has purchased loans, for which there was, at acquisition, evidence of more than insignificant deterioration of credit quality since origination. The carrying amount of those loans is as follows (in thousands): Two River Country Bank January 1, 2020 Purchase price of loans at acquisition $ 26,354 $ 24,667 Allowance for credit losses at acquisition 1,343 1,296 Non-credit discount at acquisition 3,589 5,334 Par value of acquired loans at acquisition $ 31,286 $ 31,297 In accordance with ASC 310, prior to the adoption of ASU 2016-13, the following table summarizes the changes in accretable yield for PCI loans during the three and nine months ended September 30, 2019 (in thousands): Three Months Ended Nine Months Ended 2019 2019 Beginning balance $ 3,183 $ 3,630 Acquisition — 691 Accretion (599) (1,783) Reclassification from non-accretable difference 69 115 Ending balance $ 2,653 $ 2,653

Fair Value Measurements

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 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 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 three and nine months ended September 30, 2020. 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) and Level 3 inputs which were utilized for certain state and municipal obligations known as bond anticipation notes (“BANs”). 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 September 30, 2020 and December 31, 2019, 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 Level 1 Level 2 Level 3 September 30, 2020 Items measured on a recurring basis: Debt securities available-for-sale $ 169,634 $ — $ 167,232 $ 2,402 Equity investments 63,846 63,846 — — Interest rate swap asset 55,516 — 55,516 — Interest rate swap liability (55,719) — (55,719) — Items measured on a non-recurring basis: Other real estate owned 106 — — 106 Loans measured for impairment based on the fair value of the underlying collateral 27,562 — — 27,562 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 The following table reconciles, for the three and nine months ended September 30, 2020, the beginning and ending balances for debt securities available-for-sale that are recognized at fair value on a recurring basis, in the consolidated statements of financial condition, using significant unobservable inputs (in thousands): Three Months Ended September 30, 2020 Nine Months Ended September 30, 2020 Beginning Balance $ 2,402 $ 25 Total gains (losses) included in earnings — — Purchases — 2,377 Transfers into Level 3 — — Transfers out of Level 3 — — Ending Balance $ 2,402 $ 2,402 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 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 of Philadelphia 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 September 30, 2020 and December 31, 2019 are presented in the following tables (in thousands): Fair Value Measurements at Reporting Date Using: Book Level 1 Level 2 Level 3 September 30, 2020 Financial Assets: Cash and due from banks $ 980,870 $ 980,870 $ — $ — Debt securities held-to-maturity 871,688 — 900,099 2,320 Restricted equity investments 67,505 — — 67,505 Loans receivable, net and loans held-for-sale 8,332,153 — — 8,400,464 Financial Liabilities: Deposits other than time deposits 7,721,521 — 7,721,521 — Time deposits 1,561,767 — 1,578,325 — Federal Home Loan Bank advances and other borrowings 590,393 — 619,102 — Securities sold under agreements to repurchase with retail customers 142,823 142,823 — — 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 — — 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. In general, the derivative transactions entered into by the Company fall into one of two types: an economic hedge of a derivative offering to Bank customers, or a cash flow hedge related to counter the cash variability of a recognized financial asset or liability. 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 gains of $15,000 and $364,000, respectively, in other income resulting from fair value adjustments for the three and nine months ended September 30, 2020 as compared to losses of $407,000 and $602,000, respectively, during the three and nine months ended September 30, 2019. The notional amount of derivatives not designated as hedging instruments was $711.4 million and $337.6 million at September 30, 2020 and December 31, 2019, 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. 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, which 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, which has a lease term through 2029.

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, the Company uses 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.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
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 Hooper Holdings, LLC., TRREO Holdings LLC, Casaba Real Estate Holdings Corporation, Cohensey Bridge, L.L.C., Prosperis Financial, LLC, CBNJ Investments Corp., Country Property Holdings, Inc., and TRCB Investment Corp. All significant intercompany accounts and transactions have been eliminated in consolidation.
Recent Accounting Pronouncements	In June 2016, the FASB issued ASU 2016-13, “Measurement of Credit Losses on Financial Instruments (Topic 326).” This ASU significantly changed how entities measure credit losses for financial assets and certain other instruments that are measured at amortized cost. The standard replaced the “incurred loss” approach with an “expected loss” model, which necessitates a forecast of lifetime losses. The new model, referred to as the 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. The standard’s provisions are to be applied 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 adopted ASU 2016-13 As allowed by ASC 326, the Company elected not to maintain pools of loans accounted for under ASC 310-30. At December 31, 2019, purchase credit impaired (“PCI”) loans totaled $13.3 million. In accordance with the standard, management did not reassess whether modifications individually acquired financial assets accounted for in pools were troubled debt restructured loans as of the date of adoption. Upon adoption, the Company’s PCI loans were converted to PCD loans as defined by ASC 326. The transition adjustment for the PCI loans to PCD loans resulted in a reclassification of $3.2 million from the specific credit fair value adjustment to the allowance for credit losses on loans. Management estimates the allowance balance using relevant available information, from internal and external sources, relating to past events, current conditions, and reasonable and supportable forecasts. Historical credit loss experience provides the basis for the estimation of expected credit losses. Adjustments to historical loss information are made for differences in current loan-specific risk characteristics such as differences in underwriting standards, portfolio mix, delinquency level, or term as well as changes in environmental conditions, such as changes in unemployment rates, property values, or other relevant factors. At September 30, 2020, the Company utilized the September 15, 2020 forecast, from Oxford Economics, the most recent forecast available as of quarter end, to provide the macroeconomic forecasts for select variables. Expected credit losses are estimated over the contractual term of the loans, adjusted for expected prepayments when appropriate. The contractual term excludes expected extensions, renewals, and modifications. 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. The adoption of this update did not have an 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 did not have an impact on the Company’s consolidated financial statements. Refer to Note 7 Fair Value Measurements, for additional information.
