(the “Company”) and its wholly-owned subsidiaries, OceanFirst Bank N.A. (the “Bank”) and OceanFirst Risk Management, Inc., and the Bank’s direct and indirect wholly-owned subsidiaries, OceanFirst REIT Holdings, Inc., OceanFirst Management Corp., OceanFirst Realty Corp. Casaba Real Estate Holdings Corporation, CBNJ Investments Corp., Country Property Holdings, Inc., and TRCB Investment Corp. Certain other subsidiaries were dissolved in 2020 and are included in the consolidated financial statements for previous periods. All significant intercompany accounts and transactions have been eliminated in consolidation. Certain amounts previously reported have been reclassified to conform to the current year’s presentation. The interim consolidated financial statements reflect all normal and recurring adjustments which are, in the opinion of management, considered necessary for a fair presentation of the financial condition and results of operations for the periods presented. The results of operations for the three and nine months ended September 30, 2021 are not necessarily indicative of the results of operations that may be expected for the full year 2021 or any other period. In preparing the consolidated financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the statements of financial condition and the results of operations for the period. Actual results could differ from these estimates. Certain information and note disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles have been condensed or omitted, pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”). These unaudited consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2020.

Business Combination and Asset Acquisition [Abstract]
Business Combinations	Business Combinations Two River Bancorp Acquisition On January 1, 2020, the Company completed its acquisition of Two River Bancorp (“Two River”), which after purchase accounting adjustments added $1.11 billion of assets, $940.1 million of loans, and $941.8 million of deposits. Total consideration paid for Two River was $197.1 million, including cash consideration of $48.4 million. Two River was merged with and into the Company on the date of acquisition. The acquisition was accounted for under the acquisition method of accounting. Under this method of accounting, the purchase price has been allocated to the respective assets acquired and liabilities assumed based upon their estimated fair values, net of tax. The excess of consideration paid over the estimated fair value of the net assets acquired has been recorded as goodwill. The following table summarizes the estimated fair values of the assets acquired and the liabilities assumed at the date of the acquisition for Two River, net of total consideration paid (in thousands): At January 1, 2020 Estimated Total purchase price: $ 197,050 Assets acquired: Cash and cash equivalents $ 51,102 Securities 64,381 Loans 940,072 Accrued interest receivable 2,382 Bank owned life insurance 22,440 Deferred tax assets, net 3,158 Other assets 15,956 Core deposit intangible 12,130 Total assets acquired 1,111,621 Liabilities assumed: Deposits (941,750) Other liabilities (59,026) Total liabilities assumed (1,000,776) Net assets acquired $ 110,845 Goodwill recorded in the merger $ 86,205 The calculation of goodwill is subject to change for up to one year after the date of acquisition as additional information relative to the estimates and uncertainties used to determine fair value as of the closing date become available. As of January 1, 2021, the Company finalized its review of the acquired assets and liabilities and will not be recording any further adjustments to the carrying value. Country Bank Holding Company, Inc. Acquisition On January 1, 2020, the Company completed its acquisition of Country Bank Holding Company, Inc. (“Country Bank”), which after purchase accounting adjustments added $793.7 million of assets, $618.4 million of loans, and $652.7 million of deposits. Total consideration paid for Country Bank was $112.8 million. Country Bank was merged with and into the Company on the date of acquisition. The acquisition was accounted for under the acquisition method of accounting. Under this method of accounting, the purchase price has been allocated to the respective assets acquired and liabilities assumed based upon their estimated fair values, net of tax. The excess of consideration paid over the estimated fair value of the net assets acquired has been recorded as goodwill. The following table summarizes the estimated fair values of the assets acquired and the liabilities assumed at the date of the acquisition for Country Bank, net of total consideration paid (in thousands): At January 1, 2020 Estimated Total purchase price: $ 112,836 Assets acquired: Cash and cash equivalents $ 20,799 Securities 144,499 Loans 618,408 Accrued interest receivable 1,779 Deferred tax assets, net (3,117) Other assets 9,195 Core deposit intangible 2,117 Total assets acquired 793,680 Liabilities assumed: Deposits (652,653) Other liabilities (67,240) Total liabilities assumed (719,893) Net assets acquired $ 73,787 Goodwill recorded in the merger $ 39,049 The calculation of goodwill is subject to change for up to one year after the date of acquisition as additional information relative to the estimates and uncertainties used to determine fair value as of the closing date become available. As of January 1, 2021, the Company finalized its review of the acquired assets and liabilities and will not be recording any further adjustments to the carrying value. Fair Value Measurement of Assets Assumed and Liabilities Assumed The methods used to determine the fair value of the assets acquired and liabilities assumed in the Two River and Country Bank acquisitions were as follows. Refer to Note 7, Fair Value Measurements, for a discussion of the fair value hierarchy. Securities The estimated fair values of the securities were calculated utilizing Level 2 inputs. The securities acquired are bought and sold in active markets. Prices for these instruments were obtained through security industry sources that actively participate in the buying and selling of securities. Loans The acquired loan portfolio was valued utilizing Level 3 inputs and included the use of present value techniques employing cash flow estimates and incorporated assumptions that marketplace participants would use in estimating fair values. In instances where reliable market information was not available, the Company used its own assumptions in an effort to determine reasonable fair value. Specifically, the Company utilized three separate fair value analyses which a market participant would employ in estimating the total fair value adjustment. The three separate fair valuation methodologies used were: 1) interest rate loan fair value analysis; 2) general credit fair value adjustment; and 3) specific credit fair value adjustment. To prepare the interest rate fair value analysis, loans were grouped by characteristics such as loan type, term, collateral and rate. Market rates for similar loans were obtained from various external data sources and reviewed by Company management for reasonableness. The average of these rates was used as the fair value interest rate a market participant would utilize. A present value approach was utilized to calculate the interest rate fair value adjustment. The general credit fair value adjustment was calculated using a two part general credit fair value analysis: 1) expected lifetime losses and 2) estimated fair value adjustment for qualitative factors. The expected lifetime losses were calculated using an average of historical losses of the acquired bank or historical loss experiences of peer groups where deemed appropriate. The adjustment related to qualitative factors was impacted by general economic conditions and the risk related to lack of experience with the originator’s underwriting process. To calculate the specific credit fair value adjustment, subsequent to January 1, 2020, the Company identified loans that have experienced more-than-insignificant deterioration in credit quality since origination. Loans meeting this criteria were reviewed by comparing the contractual cash flows to expected collectible cash flows. The aggregate expected cash flows less the acquisition date fair value resulted in an accretable yield amount which will be recognized over the life of the loans on a level yield basis as an adjustment to yield. Premises and Equipment Fair values are based upon appraisals from independent third parties. In addition to owned properties, Two River operated 14 properties and Country Bank operated five properties, subject to lease agreements. Deposits and Core Deposit Premium Core deposit premium represents the value assigned to non-interest-bearing demand deposits, interest-bearing checking, money market and saving accounts acquired as part of an acquisition. The core deposit premium value represents the future economic benefit, including the present value of future tax benefits, of the potential cost savings from acquiring the core deposits as part of an acquisition compared to the cost of alternative funding sources and is valued utilizing Level 2 inputs. The core deposit premium totaled $12.1 million and $2.1 million, for the acquisitions of Two River and Country Bank, respectively, and is being amortized over its estimated useful life of approximately 10 years using an accelerated method. Time deposits are not considered to be core deposits as they are assumed to have a low expected average life upon acquisition. The fair value of time deposits represents the present value of the expected contractual payments discounted by market rates for similar time deposits and is valued utilizing Level 2 inputs. Borrowings Fair value estimates are based on discounting contractual cash flows using rates which approximate the rates offered for borrowings of similar remaining maturities.

The Company noted that each issuer made all the contractually due payments when required. There were no defaults on principal or interest payments, and no interest payments were deferred. Based on management’s analysis of each individual security, the issuers appear to have the ability to meet debt service requirements over the life of the security. Furthermore, the Company does not intend to sell these corporate debt securities and it is more likely than not that the Company will not be required to sell the securities. Historically, the Company has not utilized securities sales as a source of liquidity and 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 FHLMC, FNMA, GNMA or the SBA, corporations which are chartered by the United States Government and whose debt obligations are rated AA+/Aaa by S&P and Moody’s, respectively. Additionally, there are private label commercial mortgage-backed securities with credit ratings ranging between Aaa and Aa3. The Company considers the unrealized losses to be the result of changes in interest rates, and not credit quality, which over time can have both a positive and negative impact on the estimated fair value of the mortgage-backed securities. The Company does not intend to sell these securities and it is more likely than not that the Company will not be required to sell the securities before recovery of their amortized cost. As a result, the Company concluded that these securities were not impaired at September 30, 2021. State, municipal, and sovereign debt obligations are securities issued by state, local and national governments for various purposes. The Company is not aware of any information subsequent to the purchase of any state, municipal, and sovereign debt obligations that indicates an inability on the part of an issuer to meet all of its financial commitments. The credit rating of these securities is between Aaa/AAA and Baa2/BBB. The Company has the ability and stated intention to hold these securities to maturity at which time the Company expects to receive full repayment. Current unrealized losses are considered to be the result of changes in interest rates which over time can have both a positive and negative impact on the estimated fair value of the securities. As a result, the Company concluded that these securities were not impaired as of September 30, 2021. The Company monitors the credit quality of debt securities held-to-maturity on a quarterly basis through the use of internal credit analysis supplemented by external credit ratings. The following table summarized the amortized cost of debt securities held-to-maturity at September 30, 2021, aggregated by credit quality indicator (in thousands): AAA AA A BBB BB Total As of September 30, 2021 State, municipal and sovereign debt obligations $ 31,053 $ 145,704 $ 85,435 $ 30,034 $ — $ 292,226 Corporate debt securities — 7,534 4,748 47,538 10,523 70,343 Mortgage-backed securities - other 11,093 21,067 — — — 32,160 Total debt securities held-to-maturity $ 42,146 $ 174,305 $ 90,183 $ 77,572 $ 10,523 $ 394,729 Equity Investments At September 30, 2021 and December 31, 2020, the Company held equity investments of $101.3 million and $107.1 million, respectively.

The Company categorizes all 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. Generally, risk ratings for loans on forbearance pursuant to the Coronavirus Aid, Relief and Economic Security (“CARES”) Act, extended by the Coronavirus Response and Relief Supplemental Appropriations (“CRRSA”) Act of 2021, are not re-evaluated until the initial 90-day forbearance period ends. At that time, risk ratings are updated with an emphasis on industries that were heavily impacted by the pandemic, as well as individual borrower liquidity, and other measures of resiliency as described below. The Company evaluates risk ratings on an ongoing basis and as such, adversely rated loans will be re-evaluated as government restrictions end and businesses resume normal operations. The Company uses the following definitions for risk ratings: Pass : Loans classified as Pass are well protected by the paying capacity and net worth of the borrower. Special Mention : Loans classified as Special Mention have a potential weakness that deserves management’s close attention. This includes borrowers that have been negatively affected by the pandemic but demonstrate some degree of liquidity. This liquidity may or may not be adequate to resume operations. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loan or of the Bank’s credit position at some future date. Substandard : Loans classified as Substandard are inadequately protected by the current net worth and paying capacity of the borrower or of the collateral pledged, if any. Loans so classified have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. This includes borrowers whose operations were negatively affected by the pandemic and whom, in the assessment, do not have adequate liquidity available to resume operations at levels sufficient to service their current debt levels. They are characterized by the distinct possibility that the Company will sustain some loss if the deficiencies are not corrected. Doubtful : Loans classified as Doubtful have all the weaknesses inherent in those classified as Substandard, with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions and values, highly questionable and improbable.

The modifications may include a reduction in rate, an extension in term, the capitalization of past due amounts and/or the restructuring of scheduled principal payments. Residential real estate and consumer loans where the borrower’s debt is discharged in a bankruptcy filing are also considered TDR loans. For these loans, the Bank retains its security interest in the real estate collateral. At September 30, 2021 and December 31, 2020, TDR loans totaled $19.6 million and $17.5 million, respectively. Included in the non-accrual loan total at September 30, 2021 and December 31, 2020 were $10.0 million and $5.5 million, respectively, of TDR loans. At September 30, 2021 and December 31, 2020, the Company had no specific reserves allocated to loans that are classified as TDR loans. Non-accrual loans which become TDR loans are generally returned to accrual status after six months of performance. In addition to the TDR loans included in non-accrual loans, the Company also has loans classified as accruing loans which totaled $9.6 million and $12.0 million at September 30, 2021 and December 31, 2020, respectively. The following table presents information about TDR loans which occurred during the three and nine months ended September 30, 2021 and 2020 (dollars in thousands): Number of Loans Pre-modification Post-modification Three months ended September 30, 2021 Troubled debt restructurings: Commercial real estate - owner occupied 1 $ 93 $ 110 Three months ended September 30, 2020 Troubled debt restructurings: Commercial real estate – investor 1 $ 928 $ 993 Residential real estate 1 418 418 Consumer 1 16 16 Nine months ended September 30, 2021 Troubled debt restructurings: Commercial real estate - owner occupied 1 $ 93 $ 110 Commercial real estate – investor 1 4,903 4,903 Residential real estate 3 244 336 Consumer 2 26 33 Nine months ended September 30, 2020 Troubled debt restructurings: Commercial real estate - owner occupied 1 $ 1,112 $ 1,143 Commercial real estate – investor 1 928 993 Residential real estate 5 849 865 Consumer 5 175 193 There were no TDR loans that defaulted during the three months ended September 30, 2021 which were modified within the preceding year. There was one TDR commercial real estate - investor loan for $923,000 that defaulted during the nine months ended September 30, 2021 which was modified within the preceding year and the loan is now current. There were no TDR loans that defaulted during the three and nine months ended September 30, 2020 which were modified within the preceding year. In response to the COVID-19 pandemic and its economic impact on customers, short-term modification programs that comply with the CARES Act, extended by the CRRSA Act, were implemented to provide temporary payment relief to those borrowers directly impacted by COVID-19. The Commercial Borrower Relief Program allowed for the deferral of principal and interest or principal only. All payments received will first be applied to all accrued and unpaid interest and the balance, if any, on account of unpaid principal, then to fees, expenses and other amounts due to the Bank. Monthly payments will continue until the maturity date when all then unpaid principal, interest, fees, and all other charges are due and payable to the Bank. The Consumer Borrower Relief Program allowed for the deferral of principal and interest. The deferred payments along with interest accrued during the deferral period are due and payable on the maturity date. Provided these loans were current as of either December 31, 2019 or the date of the modification, these loans are not considered TDR loans at September 30, 2021 and will not be reported as past due during the deferral period.

Fair Value Measurements

Fair Value Measurements	9 Months Ended

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. A fair value measurement assumes that the transaction to sell the asset or transfer the liability occurs in the principal market for the asset or liability or in the absence of a principal market, the most advantageous market for the asset or liability. The price in the principal (or most advantageous) market used to measure the fair value of the asset or liability shall not be adjusted for transaction costs. An orderly transaction is a transaction that assumes exposure to the market for a period prior to the measurement date to allow for marketing activities that are usual and customary for transactions involving such assets and liabilities; it is not a forced transaction. Market participants are buyers and sellers in the principal market that are (i) independent, (ii) knowledgeable, (iii) able to transact and (iv) willing to transact. The Company uses valuation techniques that are consistent with the market approach, the income approach and/or the cost approach. The market approach uses prices and other relevant information generated by market transactions involving identical or comparable assets and liabilities. The income approach uses valuation techniques to convert future amounts, such as cash flows or earnings, to a single present amount on a discounted basis. The cost approach is based on the amount that currently would be required to replace the service capacity of an asset (replacement costs). Valuation techniques should be consistently applied. Inputs to valuation techniques refer to the assumptions that market participants would use in pricing the asset or liability. Inputs may be observable, meaning those that reflect the assumptions market participants would use in pricing the asset or liability and developed based on market data obtained from independent sources, or unobservable, meaning those that reflect the reporting entity’s own assumptions about the assumptions market participants would use in pricing the asset or liability and developed based on the best information available in the circumstances. In that regard, a fair value hierarchy has been established for valuation inputs that gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities and the lowest priority to unobservable inputs. The fair value hierarchy is as follows: Level 1 Inputs – Unadjusted quoted prices in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date. Level 2 Inputs – Inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. These include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability (for example, interest rates, volatilities, prepayment speeds, loss severities, credit risks and default rates) or inputs that are derived principally from or corroborated by observable market data by correlations or other means. Level 3 Inputs – Significant unobservable inputs that reflect an entity’s own assumptions that market participants would use in pricing the assets or liabilities. Assets and Liabilities Measured at Fair Value A description of the valuation methodologies used for assets and liabilities measured at fair value, as well as the general classification of such instruments pursuant to the valuation hierarchy, is set forth below. Certain financial assets and financial liabilities are measured at fair value on a non-recurring basis, that is, the instruments are not measured at fair value on an ongoing basis but are subject to fair value adjustments in certain circumstances (for example, when there is evidence of impairment). Debt Securities Available-for-Sale Debt securities classified as available-for-sale are reported at fair value. Fair value for these debt securities is determined using inputs other than quoted prices that are based on market observable information (Level 2). Level 2 debt securities are priced through third-party pricing services or security industry sources that actively participate in the buying and selling of securities. Prices obtained from these sources include market quotations and matrix pricing. Matrix pricing is a mathematical technique used principally to value certain debt securities without relying exclusively on quoted prices for the specific securities, but comparing the debt securities to benchmark or comparable debt securities. Equity Investments Equity investments with readily determinable fair value are reported at fair value. Fair value for these investments is primarily determined using a quoted price in an active market or exchange (Level 1) or using inputs other than quoted prices that are based on market observable information (Level 2). Fair value for certain securities, including convertible preferred stock, was determined using broker or dealer quotes with limited levels of activity and price transparency (Level 3). Equity securities without readily determinable fair values are carried at cost less impairment, if any, plus or minus adjustments resulting from observable price changes in orderly transactions for the identical or similar investment of the same issuer. Interest Rate Derivatives The Company’s interest rate swaps and cap contracts are reported at fair value utilizing discounted cash flow models provided by an independent, third-party and observable market data (Level 2). When entering into an interest rate swap or cap contract, the Company is exposed to fair value changes due to interest rate movements, and also the potential nonperformance of the contract counterparty. Other Real Estate Owned and Loans Individually Measured for Impairment Other real estate owned and loans measured for impairment based on the fair value of the underlying collateral are recorded at estimated fair value, less estimated selling costs. Fair value is based on independent appraisals (Level 3). The following table summarizes financial assets and financial liabilities measured at fair value as of September 30, 2021 and December 31, 2020, segregated by the level of the valuation inputs within the fair value hierarchy utilized to measure fair value (in thousands): Fair Value Measurements at Reporting Date Using: Total Fair Level 1 Level 2 Level 3 September 30, 2021 Items measured on a recurring basis: Debt securities available-for-sale $ 314,620 $ — $ 314,620 $ — Equity investments 91,191 13,658 75,177 2,356 Interest rate derivative asset 27,503 — 27,503 — Interest rate derivative liability (27,589) — (27,589) — Items measured on a non-recurring basis: Equity investments 10,123 — — 10,123 Other real estate owned 106 — — 106 Loans measured for impairment based on the fair value of the underlying collateral 22,114 — — 22,114 December 31, 2020 Items measured on a recurring basis: Debt securities available-for-sale $ 183,302 $ — $ 183,302 $ — Equity investments 107,079 104,539 — 2,540 Interest rate derivative asset 45,289 — 45,289 — Interest rate derivative liability (45,429) — (45,429) — Items measured on a non-recurring basis: Other real estate owned 106 — — 106 Loans measured for impairment based on the fair value of the underlying collateral 35,366 — — 35,366 The following table reconciles, for the three and nine months ended September 30, 2021 and 2020, the beginning and ending balances for equity investments and debt securities available-for-sale that are recognized at fair value on a recurring basis, in the consolidated statements of financial condition, using significant unobservable inputs (in thousands): For the Three Months Ended September 30, For the Nine Months Ended September 30, 2021 2020 2021 2020 Equity Investments Debt Securities Equity Investments Debt Securities Beginning balance $ 2,978 $ 2,402 $ 2,540 $ 25 Total losses included in earnings (622) — (184) — Purchases — — — 2,377 Ending balance $ 2,356 $ 2,402 $ 2,356 $ 2,402 There were no debt securities in Level 3 for the three and nine months ended September 30, 2021. There were no equity securities in Level 3 for the three and nine months ended September 30, 2020. The Company recognizes transfers between levels of the valuation hierarchy at the end of the applicable reporting periods. There were no transfers into or out of Level 3 assets or liabilities in the fair value hierarchy for the three and nine months ended September 30, 2021 and 2020. Assets and Liabilities Disclosed at Fair Value A description of the valuation methodologies used for assets and liabilities disclosed at fair value, as well as the general classification of such instruments pursuant to the valuation hierarchy is set forth below. Cash and Due from Banks For cash and due from banks, the carrying amount approximates fair value. Debt Securities Held-to-Maturity Debt securities classified as held-to-maturity are carried at amortized cost, as the Company has the positive intent and ability to hold these debt securities to maturity. The Company determines the fair value of the debt securities utilizing Level 2 and, infrequently, Level 3 inputs. Most of the Company’s investment and mortgage-backed securities are fixed income instruments that are not quoted on an exchange, but are bought and sold in active markets. Prices for these instruments are obtained through third-party pricing vendors or security industry sources that actively participate in the buying and selling of debt securities. Prices obtained from these sources include market quotations and matrix pricing. Matrix pricing is a mathematical technique used principally to value certain debt securities without relying exclusively on quoted prices for the specific debt securities, but comparing the debt securities to benchmark or comparable debt securities. Management’s policy is to obtain and review all available documentation from the third-party pricing service relating to their fair value determinations, including their methodology and summary of inputs. Management reviews this documentation, makes inquiries of the third-party pricing service and decides as to the level of the valuation inputs. Based on the Company’s review of the available documentation from the third-party pricing service, management concluded that Level 2 inputs were utilized for all securities except for certain state and municipal obligations, known as Bond Anticipation Notes (“BANs”), as well as certain debt securities where management utilized Level 3 inputs, such as broker or dealer quotes with limited levels of activity and price transparency. Restricted Equity Investments The fair value for Federal Home Loan Bank of New York and Federal Reserve Bank stock is its carrying value since this is the amount for which it could be redeemed. There is no active market for this stock and the Company is required to maintain a minimum investment as stipulated by the respective agencies. Loans Receivable and Loans Held-for-Sale Fair values are estimated for portfolios of loans with similar financial characteristics. Loans are segregated by type such as residential real estate, consumer and commercial. Each loan category is further segmented into fixed and adjustable rate interest terms. Fair value of performing and non-performing loans was estimated by discounting the future cash flows, net of estimated prepayments, at a rate for which similar loans would be originated to new borrowers with similar terms. The fair value of loans was measured using the exit price notion. Deposits Other than Time Deposits The fair value of deposits with no stated maturity, such as non-interest-bearing demand deposits, savings, and interest-bearing checking accounts and money market accounts is, by definition, equal to the amount payable on demand. The related insensitivity of the majority of these deposits to interest rate changes creates a significant inherent value which is not reflected in the fair value reported. Time Deposits The fair value of time deposits is based on the discounted value of contractual cash flows. The discount rate is estimated using the rates currently offered for deposits of similar remaining maturities. Securities Sold Under Agreements to Repurchase with Retail Customers Fair value approximates the carrying amount as these borrowings are payable on demand and the interest rate adjusts monthly. Borrowed Funds Fair value estimates are based on discounting contractual cash flows using rates which approximate the rates offered for borrowings of similar remaining maturities. The book value and estimated fair value of the Company’s significant financial instruments not recorded at fair value as of September 30, 2021 and December 31, 2020 are presented in the following tables (in thousands): Fair Value Measurements at Reporting Date Using: Book Level 1 Level 2 Level 3 September 30, 2021 Financial Assets: Cash and due from banks $ 981,126 $ 981,126 $ — $ — Debt securities held-to-maturity 1,125,382 — 1,125,486 17,895 Restricted equity investments 53,017 — — 53,017 Loans receivable, net and loans held-for-sale 8,153,389 — — 8,140,267 Financial Liabilities: Deposits other than time deposits 8,918,655 — 8,918,655 — Time deposits 855,442 — 857,767 — Other borrowings 228,887 — 256,577 — Securities sold under agreements to repurchase with retail customers 143,292 143,292 — — December 31, 2020 Financial Assets: Cash and due from banks $ 1,272,134 $ 1,272,134 $ — $ — Debt securities held-to-maturity 937,253 — 952,365 16,101 Restricted equity investments 51,705 — — 51,705 Loans receivable, net and loans held-for-sale 7,750,381 — — 7,806,743 Financial Liabilities: Deposits other than time deposits 8,054,833 — 8,054,833 — Time deposits 1,372,783 — 1,383,173 — FHLB advances and other borrowings 235,471 — 251,798 — Securities sold under agreements to repurchase with retail customers 128,454 128,454 — — Limitations Fair value estimates are made at a specific point in time, based on relevant market information and information about the financial instrument. These estimates do not reflect any premium or discount that could result from offering for sale at one time the Company’s entire holdings of a particular financial instrument. Because a limited market exists for a significant portion of the Company’s financial instruments, fair value estimates are based on judgments regarding future expected loss experience, current economic conditions, risk characteristics of various financial instruments and other significant unobservable inputs. These estimates are subjective in nature and involve uncertainties and matters of significant judgment and, therefore, cannot be determined with precision. Changes in assumptions could significantly affect the estimates. Fair value estimates are based on existing balance sheet financial instruments without attempting to estimate the value of anticipated future business and the value of assets and liabilities that are not considered financial instruments. Significant assets and liabilities that are not considered financial assets or liabilities include premises and equipment, bank owned life insurance, deferred tax assets and goodwill. In addition, the tax ramifications related to the realization of the unrealized gains and losses can have a significant effect on fair value estimates and have not been considered in the estimates.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives, Hedging Activities, and Other Financial Instruments	Derivatives, Hedging Activities and Other Financial Instruments The Company enters into derivative financial instruments which involve, to varying degrees, interest rate, market and credit risk. The Company manages these risks as part of its asset and liability management process and through credit policies and procedures, seeking to minimize counterparty credit risk by establishing credit limits and collateral agreements. The Company utilizes certain derivative financial instruments to enhance its ability to manage interest rate risk that exists as part of its ongoing business operations. The derivative financial instruments entered into by the Company are an economic hedge of a derivative offering to Bank customers. The Company does not use derivative financial instruments for trading purposes. Customer Derivatives – Interest Rate Swaps and Cap Contracts The Company enters into interest rate swaps that allow commercial loan customers to effectively convert a variable-rate commercial loan agreement to a fixed-rate commercial loan agreement. Under these agreements, the Company enters into a variable-rate loan agreement with a customer in addition to an interest rate swap agreement, which serves to effectively swap the customer’s variable-rate loan into a fixed-rate loan. The Company then enters into a corresponding swap agreement with a third party in order to economically hedge its exposure through the customer agreement. The Company also enters into interest rate cap contracts that enable commercial loan customers to lock in a cap on a variable-rate commercial loan agreement. This feature prevents the loan from repricing to a level that exceeds the cap contract’s specified interest rate, which serves to hedge the risk from rising interest rates. The Company then enters into an offsetting interest rate cap contract with a third party in order to economically hedge its exposure through the customer agreement. The interest rate swaps and cap contracts with both the customers and third parties are not designated as hedges under FASB Accounting Standards Codification (“ASC”) Topic 815, Derivatives and Hedging, and are marked to market through earnings. As the interest rate swaps and cap contracts are structured to offset each other, changes to the underlying benchmark interest rates considered in the valuation of these instruments do not result in an impact to earnings; however, there may be fair value adjustments related to credit quality variations between counterparties, which may impact earnings as required by FASB ASC Topic 820, Fair Value Measurements. The Company recognized gains of $14,000 and $55,000 in other income resulting from fair value adjustments for the three and nine months ended September 30, 2021, respectively, as compared to gains of $15,000 and $364,000 in other income resulting from fair value adjustments for the three and nine months ended September 30, 2020, respectively. The notional amount of derivatives not designated as hedging instruments was $925.4 million and $725.9 million at September 30, 2021 and December 31, 2020, respectively. The table below presents the fair value of derivatives not designated as hedging instruments as well as their location on the consolidated statements of financial condition (in thousands): Fair Value Balance Sheet Location September 30, December 31, 2021 2020 Other assets $ 27,503 $ 45,289 Other liabilities 27,589 45,429 Credit Risk-Related Contingent Features

Leases [Abstract]
Leases	Leases A lease is defined as a contract, or part of a contract, that conveys the right to control the use of identified property, plant or equipment for a period of time in exchange for consideration. The Company’s leases are comprised of real estate property for branches, automated teller machine locations and office space with terms extending through 2050. The Company has one existing finance lease, which has a lease term through 2029. The following table represents the classification of the Company’s right-of-use (“ROU”) assets and lease liabilities on the consolidated statements of financial condition (in thousands): September 30, December 31, 2021 2020 Lease ROU Assets Classification Operating lease ROU assets Other assets $ 21,117 $ 22,555 Finance lease ROU asset Premises and equipment, net 1,545 1,694 Total lease ROU assets $ 22,662 $ 24,249 Lease Liabilities Operating lease liabilities (1) Other liabilities $ 21,713 $ 22,990 Finance lease liability Other borrowings 1,954 2,100 Total lease liabilities $ 23,667 $ 25,090 (1) Operating lease liabilities excludes liabilities for future rent and lease termination payments related to closed branches of $5.3 million and $7.4 million as of September 30, 2021 and December 31, 2020, respectively. The calculated amount of the ROU assets and lease liabilities are impacted by the lease term and the discount rate used to calculate the present value of the minimum lease payments. Lease agreements often include one or more options to renew the lease at the Company’s discretion. If the exercise of a renewal option is considered to be reasonably certain, the Company includes the extended term in the calculation of the ROU asset and lease liability. For the discount rate, Leases (Topic 842) requires the Company to use the rate implicit in the lease, provided the rate is readily determinable. As this rate is rarely determinable, the Company utilizes its incremental borrowing rate, at lease inception, over a similar term. For operating leases existing prior to January 1, 2019, the Company used the incremental borrowing rate for the remaining lease term as of January 1, 2019. For the finance lease, the Company utilized its incremental borrowing rate at lease inception.
