Accounting Policies [Abstract]
Summary of Significant Accounting Policies	(1) Summary of Significant Accounting Policies
	Principles of Consolidation
	The consolidated financial statements include the accounts of OceanFirst Financial Corp. (the “Company”) and its wholly-owned subsidiary, OceanFirst Bank (the “Bank”) and its wholly-owned subsidiaries, OceanFirst REIT Holdings, Inc, and its wholly-owned subsidiary OceanFirst Realty Corp., OceanFirst Services, LLC and its wholly-owned subsidiary OFB Reinsurance, Ltd., 975 Holdings, LLC. All significant intercompany accounts and transactions have been eliminated in consolidation.
	Certain amounts previously reported have been reclassified to conform to the current year’s presentation.
	Business
	The Bank provides a range of community banking services to customers through a network of branches and offices in Ocean, Monmouth, Middlesex and Mercer Counties in New Jersey. The Bank is subject to competition from other financial institutions; it is also subject to the regulations of certain regulatory agencies and undergoes periodic examinations by those regulatory authorities.
	Basis of Financial Statement Presentation
	The consolidated financial statements have been prepared in conformity with U.S. generally accepted accounting principles. The preparation of the accompanying consolidated financial statements in conformity with these accounting principles requires management to make estimates and assumptions about future events. These estimates and the underlying assumptions affect the amounts of assets and liabilities reported, disclosures about contingent assets and liabilities, and reported amounts of revenues and expenses. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for loan losses, the determination of the reserve for repurchased loans and loss sharing obligations, the valuation of mortgage servicing rights and the evaluation of securities for other-than-temporary impairment. These estimates and assumptions are based on management’s best estimates and judgment. Management evaluates its estimates and assumptions on an ongoing basis using historical experience and other factors, including the current economic environment, which management believes to be reasonable under the circumstances. Such estimates and assumptions are adjusted when facts and circumstances dictate. As future events and their effects cannot be determined with precision, actual results could differ significantly from these estimates. Changes in those estimates resulting from continuing changes in the economic environment will be reflected in the financial statements in future periods.
	Cash Equivalents
	Cash equivalents consist of interest-bearing deposits in other financial institutions and loans of Federal funds. For purposes of the consolidated statements of cash flows, the Company considers all highly liquid debt instruments with original maturities of three months or less to be cash equivalents.
	Securities
	Securities include securities held-to-maturity and securities available-for-sale. Management determines the appropriate classification at the time of purchase. If management has the positive intent not to sell and the Company would not be required to sell prior to maturity, the securities are classified as held-to-maturity securities. Such securities are stated at amortized cost. During 2013, the Company transferred $536.0 million of previously designated available-for-sale securities to held-to-maturity designation at estimated fair value. The Company has the ability and intent to hold these securities as an investment until maturity or call. The securities transferred had an unrealized loss of $13.3 million at the time of transfer which continues to be reflected in accumulated other comprehensive income, net of subsequent amortization, which is being recognized over the life of the securities. Securities in the available-for-sale category are securities which the Company may sell prior to maturity as part of its asset/liability management strategy and all marketable equity securities. Such securities are carried at estimated fair value and unrealized gains and losses, net of related tax effect, are excluded from earnings, but are included as a separate component of stockholders’ equity and as part of comprehensive income. Discounts and premiums on securities are accreted or amortized using the level-yield method over the estimated lives of the securities, including the effect of prepayments. Gains or losses on the sale of such securities are included in other income using the specific identification method.
	Other-Than-Temporary Impairments on Securities
	One of the significant estimates related to securities is the evaluation for other-than-temporary impairments. If a determination is made that a debt security is other-than-temporarily impaired, the Company will estimate the amount of the unrealized loss that is attributable to credit and all other non-credit related factors. The credit related component will be recognized as an other-than-temporary impairment charge in non-interest income as a component of gain (loss) on securities, net. The non-credit related component will be recorded as an adjustment to accumulated other comprehensive income, net of tax. If a determination is made that an equity security is other-than-temporarily impaired, the unrealized loss will be recognized as an other-than-temporary impairment charge in non-interest income as a component of gain (loss) on securities, net.
	The evaluation of securities for impairments is a quantitative and qualitative process, which is subject to risks and uncertainties and is intended to determine whether declines in the estimated fair value of investments should be recognized in current period earnings. The risks and uncertainties include changes in general economic conditions, the issuer’s financial condition and/or future prospects, the effects of changes in interest rates or credit spreads and the expected recovery period.
	On a quarterly basis the Company evaluates the securities portfolio for other-than-temporary impairment. Securities that are in an unrealized loss position are reviewed to determine if an other-than-temporary impairment is present based on certain quantitative factors. The primary factors considered in evaluating whether a decline in value is other-than-temporary include: (a) the length of time and extent to which the estimated fair value has been less than cost or amortized cost and the expected recovery period of the security, (b) the financial condition, credit rating and future prospects of the issuer, (c) whether the debtor is current on contractually obligated interest and principal payments and (d) whether the Company intends to sell the security and whether it is more likely than not that the Company will not be required to sell the security.
	Loans Receivable
	Loans receivable, other than loans held-for-sale, are stated at unpaid principal balance, plus unamortized premiums less unearned discounts, net of deferred loan origination and commitment fees and costs, and the allowance for loan losses.
	Loan origination and commitment fees and certain direct loan origination costs are deferred and the net fee or cost is recognized in interest income using the level-yield method over the contractual life of the specifically identified loans, adjusted for actual prepayments. For each loan class, a loan is considered past due when a payment has not been received in accordance with the contractual terms. Loans which are more than 90 days past due, including impaired loans, and other loans in the process of foreclosure are placed on non-accrual status. Interest income previously accrued on these loans, but not yet received, is reversed in the current period. Any interest subsequently collected is credited to income in the period of recovery only after the full principal balance has been brought current. A loan is returned to accrual status when all amounts due have been received and the remaining principal balance is deemed collectible.
	A loan is considered impaired when it is deemed probable that the Company will not collect all amounts due according to the contractual terms of the loan agreement. The Company has defined the population of impaired loans to be all non-accrual commercial real estate, multi-family, land, construction and commercial and industrial loans in excess of $250,000. Impaired loans are individually assessed to determine that the loan’s carrying value is not in excess of the estimated fair value of the collateral or the present value of the loan’s expected future cash flows. Smaller balance homogeneous loans that are collectively evaluated for impairment, such as residential mortgage loans and consumer loans, are specifically excluded from the impaired loan portfolio, except when they are modified in a trouble debt restructuring.
	Loan losses are charged-off in the period the loans, or portion, thereof are deemed uncollectible, generally after the loan becomes 120 days delinquent. The Company will record a loan charge-off (including a partial charge-off) to reduce a loan to the estimated fair value of the underlying collateral, less cost to sell, if it is determined that it is probable that recovery will come primarily from the sale of the collateral.
	Mortgage Loans Held-for-sale
	The Company regularly sells part of its mortgage loan originations in order to manage interest rate risk and liquidity. The Bank has generally sold fixed-rate mortgage loans with final maturities in excess of 15 years.
	In determining whether to retain mortgages, management considers the Company’s overall interest rate risk position, the volume of such loans, the loan yield and the types and amount of funding sources. The Company may also retain mortgage loan production in order to improve yields and increase balance sheet leverage.
	Mortgage loans held-for-sale are carried at the lower of unpaid principal balance, net, or estimated fair value on an aggregate basis. Estimated fair value is determined based on bid quotations from securities dealers.
	Allowance for Loan Losses
	The allowance for loan losses is a valuation account that reflects probable incurred losses in the loan portfolio. The adequacy of the allowance for loan losses is based on management’s evaluation of the Company’s past loan loss experience, known and inherent risks in the portfolio, adverse situations that may affect the borrower’s ability to repay, estimated fair value of any underlying collateral and current economic conditions. Additions to the allowance arise from charges to operations through the provision for loan losses or from the recovery of amounts previously charged-off. The allowance is reduced by loan charge-offs.
	The allowance for loan losses is maintained at an amount management considers sufficient to provide for probable losses. The analysis considers known and inherent risks in the loan portfolio resulting from management’s continuing review of the factors underlying the quality of the loan portfolio.
	The Bank’s allowance for loan losses includes specific allowances and a general allowance, each updated on a quarterly basis. A specific allowance is determined for all non-accrual loans where the estimated fair value of the underlying collateral can reasonably be evaluated. For these loans, the specific allowance represents the difference between the Bank’s recorded investment in the loan, net of any interim charge-offs, and the estimated fair value of the collateral, less estimated selling costs.
	If a loan becomes 90 days delinquent, the Bank obtains an updated collateral appraisal. For residential real estate loans, the appraisal is updated annually if the loan remains delinquent for an extended period. For non-accrual commercial real estate loans, the Bank assesses whether there has been an adverse change in the collateral value supporting the loan. The Bank utilizes information based on its knowledge of changes in real estate conditions in its lending area to identify whether a possible deterioration of collateral value has occurred. Based on the severity of the changes in market conditions, management determines if an updated commercial real estate appraisal is warranted or if downward adjustments to the previous appraisal are warranted. If it is determined that the deterioration of the collateral value is significant enough to warrant ordering a new appraisal, an estimate of the downward adjustments to the existing appraised value is used in assessing if additional specific reserves are necessary until the updated appraisal is received.
	A general allowance is determined for all loans that are not individually evaluated for a specific allowance. In determining the level of the general allowance, the Bank segments the loan portfolio into various loan segments and classes as follows:


	Loan Portfolio Segment		Loan Class
	Residential real estate:	–	Residential
		–	Residential construction
	Commercial real estate:	–	Commercial
		–	Construction and land
	Consumer:	–	Consumer
	Commercial and industrial:	–	Commercial and industrial
	The loan portfolio is further segmented by delinquency status and risk rating (Pass, Special Mention, Substandard and Doubtful). An estimated loss factor is then applied to each risk tranche. To determine the loss factor, the Bank utilizes historical loss experience as a percent of loan principal adjusted for certain qualitative factors and the loss emergence period.
	The Bank’s historical loss experience is based on a rolling 24-month look-back period for all loan segments. This was selected based on (1) management’s judgment that this period captures sufficient loss events (in both dollar terms and number of individual events) to be relevant; and (2) that the Bank’s underwriting criteria and risk characteristics have remained relatively stable throughout this period.
	The historical loss experience is adjusted for certain qualitative factors including, but not limited to, (1) delinquency trends, (2) net charge-off trends, (3) nature and volume of the loan portfolio, (4) loan policies and underwriting standards, (5) experience and ability of lending personnel, (6) changes in current economic conditions, (7) concentrations of credit, (8) loan review system, and external factors such as (9) local competition and (10) regulation. The Bank considers the applicability of each of these qualitative factors in estimating the general allowance for each loan portfolio segment. Each quarter, the conditions that existed in the 24-month look-back period are compared to current conditions to support a conclusion as to which qualitative adjustments are (or are not) deemed necessary for a particular portfolio segment.
	The Bank calculates and analyzes the loss emergence period on an annual basis or more frequently if conditions warrant. The Bank’s methodology is to use loss events in the past 8 quarters to determine the loss emergence period for each loan segment. The loss emergence period is specific to each loan segment and determined based on (1) the occurrence of a loss event which resulted in a potential loss and (2) confirmation of the potential loss is deemed to occur when the Bank records an initial charge-off on the loan or downgrades the risk-weighting to substandard or doubtful.
	The adjusted loss factors are then applied to each risk tranche. Existing economic conditions which the Bank considered to estimate the allowance for loan losses include local and regional trends in economic growth, unemployment and real estate values. In evaluating the qualitative factors as of December 31, 2014, the Company considered the potential adverse impact of actual and proposed increases to flood insurance premiums which may stress borrowers’ ability to repay their loans or lower real estate values in certain flood prone areas; the recent recruitment of commercial lenders and the related accelerated growth in commercial real estate loans; and the Company’s recent emphasis on construction-to-permanent residential construction loans attributable to local rebuilding after the damage caused by superstorm Sandy.
	The Bank also maintains an unallocated portion of the allowance for loan losses. The primary purpose of the unallocated component is to account for the inherent imprecision of the overall loss estimation process including the periodic updating of appraisals, commercial loan risk ratings, and continued economic uncertainty that may not be fully captured in the Company’s loss history or the qualitative factors.
	Upon completion of the aforementioned procedures, an overall management review is performed including ratio analyses to identify divergent trends compared with the Bank’s own historical loss experience, the historical loss experience of the Bank’s peer group and management’s understanding of general regulatory expectations. Based on that review, management may identify issues or factors that previously had not been considered in the estimation process, which may warrant further analysis or adjustments to estimated loss factors or the allowance for loan losses.
	Reserve for Repurchased Loans and Loss Sharing Obligations
	The reserve for repurchased loans and loss sharing obligations relates to potential losses on loans sold which may have to be repurchased due to a violation of representations and warranties and an estimate of the Bank’s obligation under a loss sharing arrangement for loans sold to the Federal Home Loan Bank (“FHLB”). Provisions for losses are charged to gain on sale of loans and credited to the reserve while actual losses are charged to the reserve. The reserve represents the Company’s estimate of the total losses expected to occur and is considered to be adequate by management based upon the Company’s evaluation of the potential exposure related to the loan sale agreements over the period of repurchase risk. The reserve for repurchased loans and loss sharing obligations is included in other liabilities on the Company’s consolidated statement of financial condition.
	Mortgage Servicing Rights (“MSR”)
	The Company recognizes as a separate asset the rights to service mortgage loans, whether those rights are acquired through purchase or loan origination activities. MSR are amortized in proportion to and over the estimated period of net servicing income. The estimated fair value of MSR is determined through a discounted analysis of future cash flows, incorporating numerous assumptions including servicing income, servicing costs, market discount rates, prepayment speeds and default rates, as well as the information obtained from the Company’s recent sale of MSR. Impairment of the MSR is assessed on a quarterly basis on the estimated fair value of those rights with any impairment recognized as a component of loan servicing fee income. Impairment is measured by risk strata based on the interest rate of the underlying mortgage loans. Fees earned for servicing loans are reported as income when the related mortgage loan payments are collected.
	Other Real Estate Owned (“OREO”)
	Other real estate owned is carried at the lower of cost or estimated fair value, less estimated costs to sell. When a property is acquired, the excess of the loan balance over estimated fair value is charged to the allowance for loan losses. Operating results from real estate owned, including rental income, operating expenses, gains and losses realized from the sales of other real estate owned and subsequent write-downs are recorded as incurred.
	Premises and Equipment
	Land is carried at cost and premises and equipment, including leasehold improvements, are stated at cost less accumulated depreciation and amortization. Depreciation and amortization are computed using the straight-line method over the estimated useful lives of the assets or leases. Depreciable lives are as follows: computer equipment: 3 years; furniture, fixtures and other electronic equipment: 5 years; building improvements: 10 years; and buildings: 30 years. Repair and maintenance items are expensed and improvements are capitalized. Gains and losses on dispositions are reflected in current operations.
	Income Taxes
	The Company utilizes the asset and liability method of accounting for income taxes. Under this method, deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. Any interest and penalties on taxes payable are included as part of the provision for income taxes.
	Impact of New Accounting Pronouncements
	In January 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-04, “Receivables – Troubled Debt Restructurings by Creditors (Subtopic 310-40) Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure”, which applies to all creditors who obtain physical possession of residential real estate property collateralizing a consumer mortgage loan in satisfaction of a receivable. The amendments in this update clarify when an in substance repossession or foreclosure occurs and requires disclosure of both (1) the amount of foreclosed residential real estate property held by a creditor and (2) the recorded investment in consumer mortgage loans collateralized by residential real estate property that are in the process of foreclosure. The amendments in ASU 2014-04 are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2014. The adoption of this standard is not expected to have a material impact on the Company’s consolidated financial statements.
	Comprehensive Income
	Comprehensive income is comprised of net income and other comprehensive income (loss). Other comprehensive income (loss) includes items recorded directly in equity, such as unrealized gains or losses on securities available-for-sale and accretion of unrealized loss on securities reclassified to held-to-maturity.
	Bank Owned Life Insurance (“BOLI”)
	Bank Owned Life Insurance is accounted for using the cash surrender value method and is recorded at its realizable value. The Company’s BOLI is invested in a separate account insurance product which is invested in a fixed income portfolio. The separate account includes stable value protection which maintains realizable value at book value with investment gains and losses amortized over future periods. The change in the net asset value is included in other non-interest income.
	Segment Reporting
As a community-oriented financial institution, substantially all of the Bank’s operations involve the delivery of loan and deposit products to customers. The Bank makes operating decisions and assesses performance based on an ongoing review of these community banking operations, which constitute the only operating segment for financial reporting purposes.
Earnings Per Share
Basic earnings per share is computed by dividing net income available to common stockholders by the weighted average number of shares of common stock outstanding. Diluted earnings per share is calculated by dividing net income available to common stockholders by the weighted average number of shares of common stock outstanding plus potential common stock, utilizing the treasury stock method. All share amounts exclude unallocated shares of stock held by the Employee Stock Ownership Plan (“ESOP”) and the Incentive Plan.

	Applicable regulations require the Bank to maintain minimum levels of regulatory capital. Under the regulations in effect at December 31, 2014, the Bank was required to maintain a minimum ratio of tangible capital to total adjusted assets of 1.5%; a minimum ratio of Tier 1 capital to risk weighted assets of 4.0%; and, a minimum ratio of total (core and supplementary) capital to risk-weighted assets of 8.0%.
	Under the regulatory framework for prompt corrective action, Federal regulators are required to take certain supervisory actions (and may take additional discretionary actions) with respect to an undercapitalized institution. Such actions could have a direct material effect on the institution’s financial statements. The regulations establish a framework for the classification of banking institutions into five categories: well-capitalized, adequately capitalized, undercapitalized, significantly undercapitalized and critically undercapitalized. Generally an institution is considered well-capitalized if it has a Tier 1 risk-based ratio of at least 6.0% and a total risk-based capital ratio of at least 10.0%. At December 31, 2014 and 2013, the Bank was considered well-capitalized.
	The following is a summary of the Bank’s actual capital amounts and ratios as of December 31, 2014 and 2013 compared to the regulatory minimum capital adequacy requirements and the regulatory requirements for classification as a well-capitalized institution (in thousands).

	Applicable regulations impose limitations upon all capital distributions by the Bank, such as dividends and payments to repurchase or otherwise acquire shares. The Bank may not declare or pay cash dividends on or repurchase any of its shares of common stock if the effect thereof would cause stockholders’ equity to be reduced below applicable regulatory capital maintenance requirements or if such declaration and payment would otherwise violate regulatory requirements.

For the year ended December 31, 2013, $536.0 million of previously-designated available-for-sale securities were transferred to a held-to-maturity designation at estimated fair value. The reclassification for the year ended December 31, 2013 is permitted as the Company has appropriately determined the ability and intent to hold these securities as an investment until maturity or call. The securities transferred had an unrealized net loss of $13.3 million at the time of transfer which continues to be reflected in accumulated other comprehensive loss on the consolidated balance sheet, net of subsequent amortization, which is being recognized over the life of the securities. The carrying value of the held-to-maturity investment securities at December 31, 2014 and 2013 are as follows (in thousands):

Realized gains on the sale of securities were $1,031,000, $46,000 and $226,000 for the years ended December 31, 2014, 2013 and 2012, respectively. There were no realized losses during 2014, 2013 and 2012 on the sale of securities available-for-sale.
The amortized cost and estimated fair value of investment securities at December 31, 2014 by contractual maturity, are shown below (in thousands). Actual maturities will differ from contractual maturities because issuers may have the right to call or prepay obligations with or without call or prepayment penalties. At December 31, 2014, corporate debt securities with an amortized cost and estimated fair value of $55.0 million and $45.3 million, respectively, were callable prior to the maturity date.

At December 31, 2014, the estimated fair value of each corporate debt security was below cost. However, the total estimated fair value of the corporate debt securities has steadily increased over the past several years. The corporate debt securities are issued by other financial institutions with credit ratings ranging from a high of A3 to a low of Ba1 as rated by one of the internationally-recognized credit rating services. These floating-rate securities were purchased in 1998 and have paid coupon interest continuously since issuance. Floating-rate debt securities such as these pay a fixed interest rate spread over 90-day LIBOR. Following the purchase of these securities, the required credit spread increased for these types of securities causing a decline in the market price. The Company concluded that unrealized losses on corporate debt securities were only temporarily impaired at December 31, 2014. 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. All of the financial institutions were also considered well-capitalized. Credit spreads have now decreased for these types of securities and market prices have improved. 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 have the intent to sell these corporate debt securities and it is more likely than not that the Company will not be required to sell the securities. The Company has held the securities continuously since 1998 and expects to receive its full principal at maturity in 2028 or prior if called by the issuer. Historically, the Company has not utilized security 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”) or Federal National Mortgage Association (“FNMA”), 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 or negative impact on the estimated fair value of the mortgage-backed securities. The Company does not intend to sell these securities and it is more likely than not that the Company will not be required to sell the securities before recovery of their amortized cost. As a result, the Company concluded that these securities were only temporarily impaired at December 31, 2014.

	The Bank’s mortgage loans are pledged to secure FHLB advances.
	At December 31, 2014, 2013 and 2012 loans in the amount of $18,307,000, $45,360,000, and $43,374,000, respectively, were three or more months delinquent or in the process of foreclosure and the Company was not accruing interest income on these loans and has reversed previously accrued interest. There were no loans 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 defines an impaired loan as all non-accrual commercial real estate, multi-family, land, construction and commercial and industrial loans in excess of $250,000. Impaired loans also include all loans modified as troubled debt restructurings. At December 31, 2014, the impaired loan portfolio totaled $36,979,000 for which there was a specific allocation in the allowance for loan losses of $2,161,000. At December 31, 2013, the impaired loan portfolio totaled $39,903,000 for which there was a specific allocation in the allowance for loan losses of $3,647,000. The average balance of impaired loans for the years ended December 31, 2014, 2013 and 2012 was $41,023,000, $38,587,000, and $36,574,000, respectively. If interest income on non-accrual loans and impaired loans had been current in accordance with their original terms, approximately $1,630,000, $2,513,000 and $2,370,000, of interest income for the years ended December 31, 2014, 2013 and 2012, respectively, would have been recorded. At December 31, 2014, there were no commitments to lend additional funds to borrowers whose loans are in non-accrual status.

(A)	The reduction in the unallocated portion of the allowance for loan losses is due to the improved risk profile of the loan portfolio and related credit metrics, and the lower level of uncertainty relating to future loan losses. As a result of the bulk sale of most non-performing residential loans, the total amount of non-performing loans decreased, non-performing loans as percent of total loans decreased, and the allowance for loan losses as a percent of total non-performing loans increased, as compared to December 31, 2013

The Company categorizes all commercial and industrial, 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. This analysis is performed on a quarterly basis. The Company uses the following definitions for risk ratings:
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.
Loans not meeting the criteria above that are analyzed individually as part of the above described process are considered to be Pass related loans. Loans not rated are included in groups of homogeneous loans. As of December 31, 2014 and 2013, and based on the most recent analysis performed, the risk category of loans by class of loans is as follows (in thousands):

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 December 31, 2014 and 2013 (in thousands):

The Company classifies certain loans as troubled debt restructurings (“TDR”) when credit terms to a borrower in financial difficulty are modified. The modifications may include a reduction in rate, an extension in term and/or the capitalization of past due amounts. One-to-four family and consumer loans where the borrower’s debt is discharged in a bankruptcy filing are also considered troubled debt restructurings. For these loans, the Bank retains its security interest in the real estate collateral. Included in the non-accrual loan total at December 31, 2014, 2013 and 2012 were $2,031,000, $9,663,000 and $18,160,000, respectively, of troubled debt restructurings. At December 31, 2014, 2013 and 2012, the Company has allocated $419,000, $1,816,000 and $2,418,000, respectively, of specific reserves to loans which 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 troubled debt restructuring which are accruing at December 31, 2014, 2013 and 2012 which totaled $21,462,000, $21,456,000 and $17,733,000, respectively. All troubled debt restructurings, regardless of payment status, are considered impaired loans and are individually evaluated as part of the determination of the allowance for loan losses.
The following table presents information about troubled debt restructurings which occurred during the years ended December 31, 2014 and 2013, and troubled debt restructurings modified within the previous year and which defaulted during the years ended December 31, 2014 and 2013 (dollars in thousands):

At December 31, 2014, the servicing asset had an estimated fair value of $1,143,000 and was valued based on expected future cash flows considering a weighted average discount rate of 9.7%, a weighted average constant prepayment rate on mortgages of 11.9% and a weighted average life of 7.3 years. At December 31, 2013, the servicing asset had an estimated fair value of $7,458,000 and was valued based on expected future cash flows, considering a weighted average discount rate of 9.5%, a weighted average constant prepayment rate on mortgages of 8.6% and a weighted average life of 9.5 years. As of December 31, 2014, estimated future servicing amortization through 2019 based on the prepayment assumptions utilized in the December 31, 2014 valuation, is as follows: $244,000 for 2015, $166,000 for 2016, $95,000 for 2017, $66,000 for 2018 and $48,000 for 2019. Actual results will vary depending upon the level of repayments on the loans currently serviced.

Net deferred tax assets		$	15,589			$	15,354

At December 31, 2014, 2013 and 2012, the Company determined that it is not required to establish a valuation reserve for the remaining net deferred tax assets since it is “more likely than not” that the net deferred tax assets will be realized through future reversals of existing taxable temporary differences, future taxable income and tax planning strategies. The conclusion that it is “more likely than not” that the remaining net deferred tax assets will be realized is based on the history of earnings and the prospects for continued growth. Management will continue to review the tax criteria related to the recognition of deferred tax assets.
Retained earnings at December 31, 2014 includes approximately $10,750,000 for which no provision for income tax has been made. This amount represents an allocation of income to bad debt deductions for tax purposes only. Events that would result in taxation of these reserves include failure to qualify as a bank for tax purposes, distributions in complete or partial liquidation, stock redemptions and excess distributions to shareholders. At December 31, 2014, the Company had an unrecognized deferred tax liability of $4,391,000 with respect to this reserve.
There were no unrecognized tax benefits for the years ended December 31, 2014, 2013 and 2012. The tax years that remain subject to examination by the Federal government include the year ended December 31, 2011 and forward. The tax years that remain subject to examination by the States of New Jersey and New York include the years ended December 31, 2010 and forward.

Employee Stock Ownership Plan	Dec. 31, 2014
Compensation and Retirement Disclosure [Abstract]
Employee Stock Ownership Plan	(11) Employee Stock Ownership Plan
	As part of its mutual to stock conversion, the Bank established an Employee Stock Ownership Plan and in 2006 the Bank established a Matching Contribution Employee Stock Ownership Plan (collectively the “ESOP”) to provide retirement benefits for eligible employees. All full-time employees are eligible to participate in the ESOP after they attain age 21 and complete one year of service during which they work at least 1,000 hours. ESOP shares are allocated among participants on the basis of compensation earned during the year. Employees are fully vested in their ESOP account after the completion of five years of credited service or completely if service was terminated due to death, retirement, disability or change in control of the Company. ESOP participants are entitled to receive distributions from the ESOP account only upon termination of service, which includes retirement and death except that a participant may elect to have dividends distributed as a cash payment on a quarterly basis.
	The ESOP originally borrowed $13,421,000 from the Company to purchase 2,013,137 shares of common stock issued in the conversion. On May 12, 1998, the initial loan agreement was amended to allow the ESOP to borrow an additional $8,200,000 in order to fund the purchase of 633,750 shares of common stock. At the same time the term of the loan was extended from the initial twelve years to thirty years. As part of the establishment of the Matching Contribution Employee Stock Ownership Plan the term of the loan was reduced by one year and now expires in 2026. The amended loan is to be repaid from contributions by the Bank to the ESOP trust. The Bank is required to make contributions to the ESOP in amounts at least equal to the principal and interest requirement of the debt, assuming a fixed interest rate of 8.25%.
	The Bank’s obligation to make such contributions is reduced to the extent of any dividends paid by the Company on unallocated shares and any investment earnings realized on such dividends. As of December 31, 2014 and 2013, contributions to the ESOP, which were used to fund principal and interest payments on the ESOP debt, totaled $512,000 and $515,000, respectively. During 2014 and 2013, $209,000 and $221,000, respectively, of dividends paid on unallocated ESOP shares were used for debt service. At December 31, 2014 and 2013, the loan had an outstanding balance of $3,707,000 and $3,897,000, respectively, and the ESOP had unallocated shares of 394,816 and 428,749, respectively. At December 31, 2014, the unallocated shares had a fair value of $6,767,000. The unamortized balance of the ESOP is shown as unallocated common stock held by the ESOP and is reflected as a reduction of stockholders’ equity.
	For the years ended December 31, 2014, 2013 and 2012, the Bank recorded compensation expense related to the ESOP of $570,000, $538,000 and $480,000, respectively, including $284,000, $250,000 and $191,000, respectively, representing additional compensation expense to reflect the increase in the average fair value of committed to be released and allocated shares in excess of the Bank’s cost. As of December 31, 2014, 2,218,138 shares had been allocated to participants and 33,932 shares were committed to be released.

Incentive Plan	(12) Incentive Plan
	The Company has established the Amended and Restated OceanFirst Financial Corp. 1997 Incentive Plan (the “Incentive Plan”) which authorizes the granting of stock options and awards of Common Stock and the OceanFirst Financial Corp. 2000 Stock Option Plan which authorizes the granting of stock options. On April 24, 2003 the Company’s shareholders ratified an amendment of the OceanFirst Financial Corp. 2000 Stock Option Plan which increased the number of shares available under option. On April 20, 2006 the OceanFirst Financial Corp. 2006 Stock Incentive Plan was approved which authorizes the granting of stock options or awards of common stock. On May 5, 2011, the OceanFirst Financial Corp. 2011 Stock Incentive Plan was approved which also authorizes the granting of stock options or awards of common stock. The purpose of these plans is to attract and retain qualified personnel in key positions, provide officers, employees and non-employee directors (“Outside Directors”) with a proprietary interest in the Company as an incentive to contribute to the success of the Company, align the interests of management with those of other stockholders and reward employees for outstanding performance. All officers, other employees and Outside Directors of the Company and its affiliates are eligible to receive awards under the plans.

	Under the 2011 Stock Incentive Plan, the Company is authorized to issue up to an additional 2,400,000 shares subject to option or, in lieu of options, up to 960,000 shares in the form of stock awards. At December 31, 2014, 1,483,039 options or 593,216 awards remain to be issued. Under the 2006 Stock Incentive Plan, the Company is authorized to issue up to an additional 1,000,000 shares subject to options, or in lieu of options, up to 333,333 shares in the form of stock awards. At December 31, 2014, 36,815 options or 12,272 awards remain to be issued. All options expire 10 years from the date of grant and generally vest at the rate of 20% per year. The exercise price of each option equals the closing market price of the Company’s stock on the date of grant. The Company typically issues Treasury shares to satisfy stock option exercises.
	The Company recognizes the grant-date fair value of stock options and other stock-based compensation issued to employees in the income statement. The modified prospective transition method was adopted and, as a result, the income statement includes $657,000, $502,000 and $442,000, of expense for stock option grants for the years ended December 31, 2014, 2013 and 2012, respectively. At December 31, 2014, the Company had $1.9 million in compensation cost related to non-vested awards not yet recognized. This cost will be recognized over the remaining vesting period of 2.6 years.
	The fair value of stock options granted by the Company was estimated through the use of the Black-Scholes option pricing model applying the following assumptions:


		2014				2013				2012
	Risk-free interest rate		2.29	%			1.47	%			1.4	%
	Expected option life		7 years				7 years				7 years

	Intrinsic value of options exercised during the year (in thousands)		131				11				106
	The risk-free interest rate is based on the U.S. Treasury rate with a term equal to the expected option life. The expected option life conforms to the Company’s actual experience. Expected volatility is based on actual historical results. Compensation cost is recognized on a straight line basis over the vesting period.

Commitments and Contingencies Disclosure [Abstract]
Commitments, Contingencies and Concentrations of Credit Risk	(13) Commitments, Contingencies and Concentrations of Credit Risk
	The Company, in the normal course of business, is party to financial instruments and commitments which involve, to varying degrees, elements of risk in excess of the amounts recognized in the consolidated financial statements. These financial instruments and commitments include unused consumer lines of credit and commitments to extend credit.
	At December 31, 2014, the following commitments and contingent liabilities existed which are not reflected in the accompanying consolidated financial statements (in thousands):


		December 31, 2014
	Unused consumer and construction loan lines of credit (primarily floating-rate)	$	120,205
	Unused commercial loan lines of credit (primarily floating-rate)		200,020
	Other commitments to extend credit:
	Fixed-Rate		61,868
	Adjustable-Rate		3,033
	Floating-Rate		5,494
	The Company’s fixed-rate loan commitments expire within 90 days of issuance and carried interest rates ranging from 3.0% to 5.49% at December 31, 2014.

	The Company’s maximum exposure to credit losses in the event of nonperformance by the other party to these financial instruments and commitments is represented by the contractual amounts. The Company uses the same credit policies in granting commitments and conditional obligations as it does for financial instruments recorded in the consolidated statements of financial condition.
	These commitments and obligations do not necessarily represent future cash flow requirements. The Company evaluates each customer’s creditworthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary, is based on management’s assessment of risk. Substantially all of the unused consumer and construction loan lines of credit are collateralized by mortgages on real estate.
	At December 31, 2014, the Company is obligated under noncancelable operating leases for premises and equipment. Rental expense under these leases aggregated approximately $1,984,000, $2,378,000 and $2,034,000 for the years ended December 31, 2014, 2013 and 2012, respectively.

	The Company grants one-to-four family and commercial first mortgage real estate loans to borrowers primarily located in Ocean, Monmouth, Middlesex and Mercer Counties, New Jersey. The Company previously offered interest-only one-to-four family mortgage loans on a limited basis, in which the borrower makes only interest payments for the first five, seven or ten years of the mortgage loan term. This feature will result in future increases in the borrower’s loan repayment when the contractually required repayments increase due to the required amortization of the principal amount. These payment increases could affect a borrower’s ability to repay the loan. The amount of interest-only one-to-four family mortgage loans at December 31, 2014 and 2013 was $17.6 million and $28.8 million, respectively. There were no interest-only one-to-four family mortgage loans on non-accrual status at December 31, 2014, compared to $2.2 million at December 31, 2013. The Company previously originated stated income loans on a limited basis through November 2010. These loans were only offered to self-employed borrowers for purposes of financing primary residences and second home properties. The amount of stated income loans at December 31, 2014 and 2013 was $27.3 million and $36.6 million, respectively. The amount of stated income loans on non-accrual status at December 31, 2014 and 2013 was $259,000 and $6.4 million, respectively. The ability of borrowers to repay their obligations is dependent upon various factors including the borrowers’ income and net worth, cash flows generated by the underlying collateral, value of the underlying collateral and priority of the Company’s lien on the property. Such factors are dependent upon various economic conditions and individual circumstances beyond the Company’s control; the Company is, therefore, subject to risk of loss. A decline in real estate values could cause some residential and commercial mortgage loans to become inadequately collateralized, which would expose the Bank to a greater risk of loss.
	The Company believes its lending policies and procedures adequately minimize the potential exposure to such risks. Collateral and/or guarantees are required for all loans.
	The Company is a defendant in certain claims and legal actions arising in the ordinary course of business. Management and its legal counsel are of the opinion that the ultimate disposition of these matters will not have a material adverse effect on the Company’s consolidated financial condition, results of operations or liquidity.

Reserve for Repurchased Loans and Loss Sharing Obligations	(14) Reserve for Repurchased Loans and Loss Sharing Obligations
	The reserve for repurchased loans and loss sharing obligations was established to provide for expected losses related to repurchase requests which may be received on residential mortgage loans previously sold to investors and other loss sharing obligations. The Company prepares a comprehensive analysis of the adequacy of the reserve for repurchased loans and loss sharing obligations at each quarter-end. The reserve includes a specific loss estimate on the outstanding loan repurchase requests based on the estimated fair value of the underlying collateral modified by the likelihood of loss which is estimated based on historical experience. The reserve also includes a general loss estimate based on an estimate of loans likely to be returned for repurchase and the estimated loss on those loans. Finally, the reserve also includes an estimate of the Bank’s obligation under a loss sharing arrangement with the FHLB relating to loans sold into their Mortgage Partnership Finance (“MPF”) program. Under this program, the Bank and the FHLB share credit risk for loans sold. The first loss position, equal to 1% of the aggregate amount of the loan pool, is absorbed by the FHLB through a reduction in credit enhancement fees paid to the Bank. The second loss position, generally covering the next 1.5% to 4.0% of the aggregate loan pool, is absorbed by the Bank. Loan losses above the combination of these two thresholds are fully absorbed by the FHLB. In establishing the reserve, the Company considered recent and historical experience, product type and volume of loan sales and the general economic environment.

Fair Value Measurements	Dec. 31, 2014
Fair Value Disclosures [Abstract]
Fair Value Measurements	(16) 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 market 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 years ended December 31, 2014, 2013 and 2012. 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).
	Securities Available-for-Sale
	Securities classified as available-for-sale are reported at fair value utilizing Level 1 and Level 2 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 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 securities without relying exclusively on quoted prices for the specific securities, but comparing the securities to benchmark or comparable securities.
	Fair value estimates are made at a point in time, based on relevant market data as well as the best information available about the security. Illiquid credit markets have resulted in inactive markets for certain of the Company’s securities. As a result, there is limited observable market data for these assets. Fair value estimates for securities for which limited observable market data is available are based on judgments regarding current economic conditions, liquidity discounts, credit and interest rate risks, and other factors. These estimates involve significant uncertainties and judgments and cannot be determined with precision. As a result, such calculated fair value estimates may not be realizable in a current sale or immediate settlement of the security.
	The Company utilizes third-party pricing services to obtain market values for its corporate bonds. Management’s policy is to obtain and review all available documentation from the third-party pricing service relating to their market value determinations, including their methodology and summary of inputs. Management reviews this documentation, makes inquiries of the third-party pricing service and makes a determination 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. The significant observable inputs include benchmark yields, reported trades, broker/dealer quotes, issuer spreads, two-sided markets, benchmark securities, bids, offers, other market information and observations of equity and credit default swap curves related to the issuer.
	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 of 15%. Fair value is based on independent appraisals.

	The following table summarizes financial assets and financial liabilities measured at fair value as of December 31, 2014 and 2013, segregated by the level of the valuation inputs within the fair value hierarchy utilized to measure fair value (in thousands):

	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.
	Securities Held-to-Maturity
	Securities classified as held-to-maturity are carried at amortized cost, as the Company has the positive intent and ability to hold these securities to maturity. The Company determines the fair value of the 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 securities. Prices obtained from these sources include market quotations and matrix pricing. Matrix pricing is a mathematical technique used principally to value certain securities without relying exclusively on quoted prices for the specific securities, but comparing the securities to benchmark or comparable securities.
	Fair value estimates are made at a point in time, based on relevant market data as well as the best information available about the security. Illiquid credit markets have resulted in inactive markets for certain of the Company’s securities. As a result, there is limited observable market data for these assets. Fair value estimates for securities for which limited observable market data is available are based on judgments regarding current economic conditions, liquidity discounts, credit and interest rate risks, and other factors. These estimates involve significant uncertainties and judgments and cannot be determined with precision. As a result, such calculated fair value estimates may not be realizable in a current sale or immediate settlement of the security.
	The Company utilizes third-party pricing services to obtain fair values for most of its securities held-to-maturity. 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 makes a determination 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. In the case of the Level 2 securities, the significant observable inputs include benchmark yields, reported trades, broker/dealer quotes, issuer spreads, two-sided markets, benchmark securities, bids, offers, other market information and observations of equity and credit default swap curves related to the issuer. Management based its fair value estimate of the BANs on the local nature of the issuing entities, the short-term life of the security and current economic conditions.
	Federal Home Loan Bank of New York Stock
	The fair value for Federal Home Loan Bank of New York 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 based upon the outstanding balance of mortgage related assets and outstanding borrowings.
	Loans
	Fair values are estimated for portfolios of loans with similar financial characteristics. Loans are segregated by type such as residential mortgage, construction, 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. Fair values estimated in this manner do not fully incorporate an exit price approach to fair value, but instead are based on a comparison to current market rates for comparable loans.
	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 are, 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 are based on the discounted value of contractual cash flows. The discount rate is estimated using the rates currently offered for deposits of similar remaining maturities.
	Securities Sold Under Agreements to Repurchase with Retail Customers
	Fair value approximates the carrying amount as these borrowings are payable on demand and the interest rate adjusts monthly.
	Borrowed Funds
	Fair value estimates are based on discounting contractual cash flows using rates which approximate the rates offered for borrowings of similar remaining maturities.

	The book value and estimated fair value of the Bank’s significant financial instruments not recorded at fair value as of December 31, 2014 and December 31, 2013 are presented in the following tables (in thousands):

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 deferred tax assets, and premises and equipment. In addition, the tax ramifications related to the realization of the unrealized gains and losses can have a significant effect on fair value estimates and have not been considered in the estimates.

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2014
Accounting Policies [Abstract]
Principles of Consolidation	Principles of Consolidation
	The consolidated financial statements include the accounts of OceanFirst Financial Corp. (the “Company”) and its wholly-owned subsidiary, OceanFirst Bank (the “Bank”) and its wholly-owned subsidiaries, OceanFirst REIT Holdings, Inc, and its wholly-owned subsidiary OceanFirst Realty Corp., OceanFirst Services, LLC and its wholly-owned subsidiary OFB Reinsurance, Ltd., 975 Holdings, LLC. All significant intercompany accounts and transactions have been eliminated in consolidation.
	Certain amounts previously reported have been reclassified to conform to the current year’s presentation.
Business	Business
	The Bank provides a range of community banking services to customers through a network of branches and offices in Ocean, Monmouth, Middlesex and Mercer Counties in New Jersey. The Bank is subject to competition from other financial institutions; it is also subject to the regulations of certain regulatory agencies and undergoes periodic examinations by those regulatory authorities.
Basis of Financial Statement Presentation	Basis of Financial Statement Presentation
	The consolidated financial statements have been prepared in conformity with U.S. generally accepted accounting principles. The preparation of the accompanying consolidated financial statements in conformity with these accounting principles requires management to make estimates and assumptions about future events. These estimates and the underlying assumptions affect the amounts of assets and liabilities reported, disclosures about contingent assets and liabilities, and reported amounts of revenues and expenses. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for loan losses, the determination of the reserve for repurchased loans and loss sharing obligations, the valuation of mortgage servicing rights and the evaluation of securities for other-than-temporary impairment. These estimates and assumptions are based on management’s best estimates and judgment. Management evaluates its estimates and assumptions on an ongoing basis using historical experience and other factors, including the current economic environment, which management believes to be reasonable under the circumstances. Such estimates and assumptions are adjusted when facts and circumstances dictate. As future events and their effects cannot be determined with precision, actual results could differ significantly from these estimates. Changes in those estimates resulting from continuing changes in the economic environment will be reflected in the financial statements in future periods.
Cash Equivalents	Cash Equivalents
	Cash equivalents consist of interest-bearing deposits in other financial institutions and loans of Federal funds. For purposes of the consolidated statements of cash flows, the Company considers all highly liquid debt instruments with original maturities of three months or less to be cash equivalents.
Securities	Securities
	Securities include securities held-to-maturity and securities available-for-sale. Management determines the appropriate classification at the time of purchase. If management has the positive intent not to sell and the Company would not be required to sell prior to maturity, the securities are classified as held-to-maturity securities. Such securities are stated at amortized cost. During 2013, the Company transferred $536.0 million of previously designated available-for-sale securities to held-to-maturity designation at estimated fair value. The Company has the ability and intent to hold these securities as an investment until maturity or call. The securities transferred had an unrealized loss of $13.3 million at the time of transfer which continues to be reflected in accumulated other comprehensive income, net of subsequent amortization, which is being recognized over the life of the securities. Securities in the available-for-sale category are securities which the Company may sell prior to maturity as part of its asset/liability management strategy and all marketable equity securities. Such securities are carried at estimated fair value and unrealized gains and losses, net of related tax effect, are excluded from earnings, but are included as a separate component of stockholders’ equity and as part of comprehensive income. Discounts and premiums on securities are accreted or amortized using the level-yield method over the estimated lives of the securities, including the effect of prepayments. Gains or losses on the sale of such securities are included in other income using the specific identification method.
Other-Than-Temporary Impairments on Securities	Other-Than-Temporary Impairments on Securities
	One of the significant estimates related to securities is the evaluation for other-than-temporary impairments. If a determination is made that a debt security is other-than-temporarily impaired, the Company will estimate the amount of the unrealized loss that is attributable to credit and all other non-credit related factors. The credit related component will be recognized as an other-than-temporary impairment charge in non-interest income as a component of gain (loss) on securities, net. The non-credit related component will be recorded as an adjustment to accumulated other comprehensive income, net of tax. If a determination is made that an equity security is other-than-temporarily impaired, the unrealized loss will be recognized as an other-than-temporary impairment charge in non-interest income as a component of gain (loss) on securities, net.
	The evaluation of securities for impairments is a quantitative and qualitative process, which is subject to risks and uncertainties and is intended to determine whether declines in the estimated fair value of investments should be recognized in current period earnings. The risks and uncertainties include changes in general economic conditions, the issuer’s financial condition and/or future prospects, the effects of changes in interest rates or credit spreads and the expected recovery period.
	On a quarterly basis the Company evaluates the securities portfolio for other-than-temporary impairment. Securities that are in an unrealized loss position are reviewed to determine if an other-than-temporary impairment is present based on certain quantitative factors. The primary factors considered in evaluating whether a decline in value is other-than-temporary include: (a) the length of time and extent to which the estimated fair value has been less than cost or amortized cost and the expected recovery period of the security, (b) the financial condition, credit rating and future prospects of the issuer, (c) whether the debtor is current on contractually obligated interest and principal payments and (d) whether the Company intends to sell the security and whether it is more likely than not that the Company will not be required to sell the security.
Loans Receivable	Loans Receivable
	Loans receivable, other than loans held-for-sale, are stated at unpaid principal balance, plus unamortized premiums less unearned discounts, net of deferred loan origination and commitment fees and costs, and the allowance for loan losses.
	Loan origination and commitment fees and certain direct loan origination costs are deferred and the net fee or cost is recognized in interest income using the level-yield method over the contractual life of the specifically identified loans, adjusted for actual prepayments. For each loan class, a loan is considered past due when a payment has not been received in accordance with the contractual terms. Loans which are more than 90 days past due, including impaired loans, and other loans in the process of foreclosure are placed on non-accrual status. Interest income previously accrued on these loans, but not yet received, is reversed in the current period. Any interest subsequently collected is credited to income in the period of recovery only after the full principal balance has been brought current. A loan is returned to accrual status when all amounts due have been received and the remaining principal balance is deemed collectible.
	A loan is considered impaired when it is deemed probable that the Company will not collect all amounts due according to the contractual terms of the loan agreement. The Company has defined the population of impaired loans to be all non-accrual commercial real estate, multi-family, land, construction and commercial and industrial loans in excess of $250,000. Impaired loans are individually assessed to determine that the loan’s carrying value is not in excess of the estimated fair value of the collateral or the present value of the loan’s expected future cash flows. Smaller balance homogeneous loans that are collectively evaluated for impairment, such as residential mortgage loans and consumer loans, are specifically excluded from the impaired loan portfolio, except when they are modified in a trouble debt restructuring.
	Loan losses are charged-off in the period the loans, or portion, thereof are deemed uncollectible, generally after the loan becomes 120 days delinquent. The Company will record a loan charge-off (including a partial charge-off) to reduce a loan to the estimated fair value of the underlying collateral, less cost to sell, if it is determined that it is probable that recovery will come primarily from the sale of the collateral.
Mortgage Loans Held-for-sale	Mortgage Loans Held-for-sale
	The Company regularly sells part of its mortgage loan originations in order to manage interest rate risk and liquidity. The Bank has generally sold fixed-rate mortgage loans with final maturities in excess of 15 years.
	In determining whether to retain mortgages, management considers the Company’s overall interest rate risk position, the volume of such loans, the loan yield and the types and amount of funding sources. The Company may also retain mortgage loan production in order to improve yields and increase balance sheet leverage.
	Mortgage loans held-for-sale are carried at the lower of unpaid principal balance, net, or estimated fair value on an aggregate basis. Estimated fair value is determined based on bid quotations from securities dealers.
Allowance for Loan Losses	Allowance for Loan Losses
	The allowance for loan losses is a valuation account that reflects probable incurred losses in the loan portfolio. The adequacy of the allowance for loan losses is based on management’s evaluation of the Company’s past loan loss experience, known and inherent risks in the portfolio, adverse situations that may affect the borrower’s ability to repay, estimated fair value of any underlying collateral and current economic conditions. Additions to the allowance arise from charges to operations through the provision for loan losses or from the recovery of amounts previously charged-off. The allowance is reduced by loan charge-offs.
	The allowance for loan losses is maintained at an amount management considers sufficient to provide for probable losses. The analysis considers known and inherent risks in the loan portfolio resulting from management’s continuing review of the factors underlying the quality of the loan portfolio.
	The Bank’s allowance for loan losses includes specific allowances and a general allowance, each updated on a quarterly basis. A specific allowance is determined for all non-accrual loans where the estimated fair value of the underlying collateral can reasonably be evaluated. For these loans, the specific allowance represents the difference between the Bank’s recorded investment in the loan, net of any interim charge-offs, and the estimated fair value of the collateral, less estimated selling costs.
	If a loan becomes 90 days delinquent, the Bank obtains an updated collateral appraisal. For residential real estate loans, the appraisal is updated annually if the loan remains delinquent for an extended period. For non-accrual commercial real estate loans, the Bank assesses whether there has been an adverse change in the collateral value supporting the loan. The Bank utilizes information based on its knowledge of changes in real estate conditions in its lending area to identify whether a possible deterioration of collateral value has occurred. Based on the severity of the changes in market conditions, management determines if an updated commercial real estate appraisal is warranted or if downward adjustments to the previous appraisal are warranted. If it is determined that the deterioration of the collateral value is significant enough to warrant ordering a new appraisal, an estimate of the downward adjustments to the existing appraised value is used in assessing if additional specific reserves are necessary until the updated appraisal is received.
	A general allowance is determined for all loans that are not individually evaluated for a specific allowance. In determining the level of the general allowance, the Bank segments the loan portfolio into various loan segments and classes as follows:


	Loan Portfolio Segment		Loan Class
	Residential real estate:	–	Residential
		–	Residential construction
	Commercial real estate:	–	Commercial
		–	Construction and land
	Consumer:	–	Consumer
	Commercial and industrial:	–	Commercial and industrial
	The loan portfolio is further segmented by delinquency status and risk rating (Pass, Special Mention, Substandard and Doubtful). An estimated loss factor is then applied to each risk tranche. To determine the loss factor, the Bank utilizes historical loss experience as a percent of loan principal adjusted for certain qualitative factors and the loss emergence period.
	The Bank’s historical loss experience is based on a rolling 24-month look-back period for all loan segments. This was selected based on (1) management’s judgment that this period captures sufficient loss events (in both dollar terms and number of individual events) to be relevant; and (2) that the Bank’s underwriting criteria and risk characteristics have remained relatively stable throughout this period.
	The historical loss experience is adjusted for certain qualitative factors including, but not limited to, (1) delinquency trends, (2) net charge-off trends, (3) nature and volume of the loan portfolio, (4) loan policies and underwriting standards, (5) experience and ability of lending personnel, (6) changes in current economic conditions, (7) concentrations of credit, (8) loan review system, and external factors such as (9) local competition and (10) regulation. The Bank considers the applicability of each of these qualitative factors in estimating the general allowance for each loan portfolio segment. Each quarter, the conditions that existed in the 24-month look-back period are compared to current conditions to support a conclusion as to which qualitative adjustments are (or are not) deemed necessary for a particular portfolio segment.
	The Bank calculates and analyzes the loss emergence period on an annual basis or more frequently if conditions warrant. The Bank’s methodology is to use loss events in the past 8 quarters to determine the loss emergence period for each loan segment. The loss emergence period is specific to each loan segment and determined based on (1) the occurrence of a loss event which resulted in a potential loss and (2) confirmation of the potential loss is deemed to occur when the Bank records an initial charge-off on the loan or downgrades the risk-weighting to substandard or doubtful.
	The adjusted loss factors are then applied to each risk tranche. Existing economic conditions which the Bank considered to estimate the allowance for loan losses include local and regional trends in economic growth, unemployment and real estate values. In evaluating the qualitative factors as of December 31, 2014, the Company considered the potential adverse impact of actual and proposed increases to flood insurance premiums which may stress borrowers’ ability to repay their loans or lower real estate values in certain flood prone areas; the recent recruitment of commercial lenders and the related accelerated growth in commercial real estate loans; and the Company’s recent emphasis on construction-to-permanent residential construction loans attributable to local rebuilding after the damage caused by superstorm Sandy.
	The Bank also maintains an unallocated portion of the allowance for loan losses. The primary purpose of the unallocated component is to account for the inherent imprecision of the overall loss estimation process including the periodic updating of appraisals, commercial loan risk ratings, and continued economic uncertainty that may not be fully captured in the Company’s loss history or the qualitative factors.
	Upon completion of the aforementioned procedures, an overall management review is performed including ratio analyses to identify divergent trends compared with the Bank’s own historical loss experience, the historical loss experience of the Bank’s peer group and management’s understanding of general regulatory expectations. Based on that review, management may identify issues or factors that previously had not been considered in the estimation process, which may warrant further analysis or adjustments to estimated loss factors or the allowance for loan losses.
Reserve for Repurchased Loans and Loss Sharing Obligations	Reserve for Repurchased Loans and Loss Sharing Obligations
	The reserve for repurchased loans and loss sharing obligations relates to potential losses on loans sold which may have to be repurchased due to a violation of representations and warranties and an estimate of the Bank’s obligation under a loss sharing arrangement for loans sold to the Federal Home Loan Bank (“FHLB”). Provisions for losses are charged to gain on sale of loans and credited to the reserve while actual losses are charged to the reserve. The reserve represents the Company’s estimate of the total losses expected to occur and is considered to be adequate by management based upon the Company’s evaluation of the potential exposure related to the loan sale agreements over the period of repurchase risk. The reserve for repurchased loans and loss sharing obligations is included in other liabilities on the Company’s consolidated statement of financial condition.
Mortgage Servicing Rights ("MSR")	Mortgage Servicing Rights (“MSR”)
	The Company recognizes as a separate asset the rights to service mortgage loans, whether those rights are acquired through purchase or loan origination activities. MSR are amortized in proportion to and over the estimated period of net servicing income. The estimated fair value of MSR is determined through a discounted analysis of future cash flows, incorporating numerous assumptions including servicing income, servicing costs, market discount rates, prepayment speeds and default rates, as well as the information obtained from the Company’s recent sale of MSR. Impairment of the MSR is assessed on a quarterly basis on the estimated fair value of those rights with any impairment recognized as a component of loan servicing fee income. Impairment is measured by risk strata based on the interest rate of the underlying mortgage loans. Fees earned for servicing loans are reported as income when the related mortgage loan payments are collected.
Other Real Estate Owned ("OREO")	Other Real Estate Owned (“OREO”)
	Other real estate owned is carried at the lower of cost or estimated fair value, less estimated costs to sell. When a property is acquired, the excess of the loan balance over estimated fair value is charged to the allowance for loan losses. Operating results from real estate owned, including rental income, operating expenses, gains and losses realized from the sales of other real estate owned and subsequent write-downs are recorded as incurred.
Premises and Equipment	Premises and Equipment
	Land is carried at cost and premises and equipment, including leasehold improvements, are stated at cost less accumulated depreciation and amortization. Depreciation and amortization are computed using the straight-line method over the estimated useful lives of the assets or leases. Depreciable lives are as follows: computer equipment: 3 years; furniture, fixtures and other electronic equipment: 5 years; building improvements: 10 years; and buildings: 30 years. Repair and maintenance items are expensed and improvements are capitalized. Gains and losses on dispositions are reflected in current operations.
Income Taxes	Income Taxes
	The Company utilizes the asset and liability method of accounting for income taxes. Under this method, deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. Any interest and penalties on taxes payable are included as part of the provision for income taxes.
Impact of New Accounting Pronouncements	Impact of New Accounting Pronouncements
	In January 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-04, “Receivables – Troubled Debt Restructurings by Creditors (Subtopic 310-40) Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure”, which applies to all creditors who obtain physical possession of residential real estate property collateralizing a consumer mortgage loan in satisfaction of a receivable. The amendments in this update clarify when an in substance repossession or foreclosure occurs and requires disclosure of both (1) the amount of foreclosed residential real estate property held by a creditor and (2) the recorded investment in consumer mortgage loans collateralized by residential real estate property that are in the process of foreclosure. The amendments in ASU 2014-04 are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2014. The adoption of this standard is not expected to have a material impact on the Company’s consolidated financial statements.
Comprehensive Income	Comprehensive Income
	Comprehensive income is comprised of net income and other comprehensive income (loss). Other comprehensive income (loss) includes items recorded directly in equity, such as unrealized gains or losses on securities available-for-sale and accretion of unrealized loss on securities reclassified to held-to-maturity.
Bank Owned Life Insurance ("BOLI")	Bank Owned Life Insurance (“BOLI”)
	Bank Owned Life Insurance is accounted for using the cash surrender value method and is recorded at its realizable value. The Company’s BOLI is invested in a separate account insurance product which is invested in a fixed income portfolio. The separate account includes stable value protection which maintains realizable value at book value with investment gains and losses amortized over future periods. The change in the net asset value is included in other non-interest income.
Segment Reporting	Segment Reporting
	As a community-oriented financial institution, substantially all of the Bank’s operations involve the delivery of loan and deposit products to customers. The Bank makes operating decisions and assesses performance based on an ongoing review of these community banking operations, which constitute the only operating segment for financial reporting purposes.
Earnings Per Share	Earnings Per Share
	Basic earnings per share is computed by dividing net income available to common stockholders by the weighted average number of shares of common stock outstanding. Diluted earnings per share is calculated by dividing net income available to common stockholders by the weighted average number of shares of common stock outstanding plus potential common stock, utilizing the treasury stock method. All share amounts exclude unallocated shares of stock held by the Employee Stock Ownership Plan (“ESOP”) and the Incentive Plan.

	(A)	The reduction in the unallocated portion of the allowance for loan losses is due to the improved risk profile of the loan portfolio and related credit metrics, and the lower level of uncertainty relating to future loan losses. As a result of the bulk sale of most non-performing residential loans, the total amount of non-performing loans decreased, non-performing loans as percent of total loans decreased, and the allowance for loan losses as a percent of total non-performing loans increased, as compared to December 31, 2013
