Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation Overview Brookline Bancorp, Inc. (the "Company") is a bank holding company (within the meaning of the Bank Holding Company Act of 1956, as amended) and the parent of Brookline Bank, a Massachusetts-chartered trust company; Bank Rhode Island ("BankRI"), a Rhode Island-chartered financial institution; and PCSB Bank, a New York-chartered commercial bank (collectively referred to as the "Banks"). The Banks are members of the Federal Reserve System. The Company is also the parent of Brookline Securities Corp. ("BSC") and Clarendon Private, LLC ("Clarendon Private"). The Company's primary business is to provide commercial, business and retail banking services to its corporate, municipal and retail customers through the Banks and its non-bank subsidiaries. Brookline Bank, which includes its wholly-owned subsidiaries, Longwood Securities Corp. ("LSC"), Eastern Funding LLC ("Eastern Funding") and First Ipswich Insurance Agency, operates 29 full-service banking offices in the greater Boston metropolitan area with two additional lending offices. BankRI, which includes its wholly-owned subsidiaries, Acorn Insurance Agency, BRI Realty Corp., BRI Investment Corp. and its wholly-owned subsidiary, BRI MSC Corp., operates 20 full-service banking offices in the greater Providence, Rhode Island area. Macrolease Corporation, previously a subsidiary of BankRI, was merged into Eastern Funding LLC in the second quarter of 2022. PCSB Bank, which includes its wholly-owned subsidiary, UpCounty Realty Corp., operates 14 full-service banking offices in the Lower Hudson Valley of New York. Clarendon Private is a registered investment advisor with the Securities and Exchange Commission ("SEC"). Through Clarendon Private, the Company offers a wide range of wealth management services to individuals, families, endowments and foundations to help these clients meet their long-term financial goals. The Banks' activities include acceptance of commercial, municipal and retail deposits, origination of mortgage loans on commercial and residential real estate located principally in Central New England and the Lower Hudson Valley of New York State, origination of commercial loans and leases to small- and mid-sized businesses, investment in debt and equity securities, and the offering of cash management and investment advisory services. The Company also provides specialty equipment financing through it subsidiary Eastern Funding, which operates in New York City, New York, and Plainview, New York. The Company and the Banks are supervised, examined and regulated by the Board of Governors of the Federal Reserve System (the "FRB"). As a Massachusetts-chartered trust company, Brookline Bank is subject to supervision, examination and regulation by the Massachusetts Division of Banks (the "MDOB"). As a Rhode Island-chartered financial institution, BankRI is subject to supervision, examination and regulation by the Banking Division of the Rhode Island Department of Business Regulation (the "RIBD"). As a New York- chartered commercial bank, PCSB Bank is subject to supervision, examination and regulation by the New York State Department of Financial Services. Clarendon Private is also subject to regulation by the SEC. The Federal Deposit Insurance Corporation ("FDIC") offers insurance coverage on all deposits up to $250,000 per depositor at each of the Banks. As FDIC-insured depository institutions, the Banks are also subject to supervision, examination and regulation by the FDIC. As previously disclosed, on July 31, 2019, Brookline Bank converted to a Massachusetts-chartered trust company and ended its membership in the Depositors Insurance Fund (the “DIF”), a private industry-sponsored fund which insures Massachusetts-chartered bank deposit balances in excess of federal deposit insurance coverage. Brookline Bank’s growth in deposit size necessitated its withdrawal from the DIF and the concurrent charter conversion. Term deposits in excess of the FDIC insurance coverage as of July 31, 2019 will continue to be insured by the DIF until they reach maturity. Basis of Financial Statement Presentation The unaudited consolidated financial statements of the Company presented herein have been prepared pursuant to the rules of the SEC for quarterly reports on Form 10-Q and do not include all of the information and note disclosures required by U.S. generally accepted accounting principles (“GAAP”). In the opinion of management, all adjustments (consisting of normal recurring adjustments) and disclosures considered necessary for the fair presentation of the accompanying consolidated financial statements have been included. Interim results are not necessarily reflective of the results of the entire year. The accompanying unaudited consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Annual Report on Form 10-K for the fiscal year ended December 31, 2022. The unaudited consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All significant intercompany transactions and balances are eliminated in consolidation. In preparing these consolidated financial statements, management is required to make significant estimates and assumptions that affect the reported amounts of assets, liabilities, income, expenses and disclosure of contingent assets and liabilities. Actual results could differ from those estimates based upon changing conditions, including economic conditions and future events. Material estimates that are particularly susceptible to significant changes in the near-term include the determination of the allowance for credit losses, the determination of fair market values of acquired assets and liabilities, including acquired loans, the review of goodwill and intangible assets for impairment and the review of deferred tax assets for valuation allowances. The judgments used by management in applying these critical accounting policies may be affected by a further and prolonged deterioration in the economic environment, which may result in changes to future financial results. For example, subsequent evaluations of the loan and lease portfolio, in light of the factors then prevailing, may result in significant changes in the allowance for loan and lease losses in future periods, and the inability to collect outstanding principal may result in increased loan and lease losses. Reclassification Certain previously reported amounts have been reclassified to conform to the current year's presentation. Recent Accounting Pronouncements In March 2020, the FASB issued ASU 2020-04, "Reference Rate Reform (Topic 848)-Facilitation of the Effects of Reference Rate Reform on Financial Reporting" ("ASU 2020-04") to provide optional expedients and exceptions for applying GAAP to certain contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. The amendments in this update apply only to contracts, hedging relationships, and other transactions that reference the London Interbank Offered Rate ("LIBOR") or another reference rate expected to be discontinued because of reference rate reform. The expedients and exceptions provided by the amendments do not apply to contract modifications made and hedging relationships existing as of December 31, 2022, for which an entity has elected certain optional expedients provided that those elections are retained through the end of the hedging relationship. The amendments in this update are effective for all entities as of March 12, 2020 through December 31, 2022 and do not apply to contract modifications made after December 31, 2022. In January 2021, FASB issued ASU 2021-01, "Reference Rate Reform (Topic 848)" an update to address concerns around structural risk of interbank offered rates ("IBORs"), particularly, the risk of cessation of the LIBOR. The amendments in this update clarify that certain optional expedients and exceptions in Topic 848 for contract modifications and hedge accounting apply to derivatives that are affected by the discounting transition. In December 2022, FASB issued ASU 2022-06, "Reference Rate Reform (Topic 848)" which deferred the sunset date of Topic 848 to December 31, 2024, to allow for a transition period after the sunset of LIBOR. The Company has adopted the amendments in these updates and established a LIBOR transition committee to guide the Company’s transition from LIBOR. The Company has completed much of the work to transition off the LIBOR index consistent with industry timelines. The working group has identified its products that utilize LIBOR and has implemented fallback language to facilitate the transition to alternative rates. The Company has also evaluated its infrastructure and identified fallback rates as well as started offering alternative indices and new products tied to these alternative indices. The Company does not anticipate the adoption of these standards to have a material impact to the consolidated financial statements. In October 2021, the FASB issued ASU 2021-08, "Business Combinations (Topic 805), Accounting for Contract Assets and Contract Liabilities from Contracts with Customers" which requires that an acquirer recognize and measure contract assets and contract liabilities acquired in a business combination in accordance with Topic 606, Revenue from Contracts with Customers. At the acquisition date, an acquirer should account for the related revenue contracts in accordance with Topic 606 as if it had originated the contracts. The Company adopted ASU 2021-08 as of January 1, 2023 on a prospective basis. The adoption did not have a material impact on the Company's consolidated financial statements. In March 2022, the FASB issued ASU 2022-02, "Financial Instruments - Credit Losses (Topic 326), Troubled Debt Restructurings and Vintage Disclosures" which addresses concerns regarding the complex accounting for loans modified as troubled debt restructurings (“TDRs”) and also the disclosure of gross writeoff information included in required vintage disclosures. The Company adopted ASU 2022-02 as of January 1, 2023. The enhanced disclosure requirements provided for by ASU 2022-02 were adopted on a prospective basis. Reporting periods prior to the adoption of ASU 2022-02 are presented in accordance with the applicable GAAP. The adoption did not have a material impact on the Company’s consolidated financial statements. Additional details can be found in Note 5, "Allowance for Credit Losses".

Business Combination and Asset Acquisition [Abstract]
Acquisitions	Acquisitions PCSB Financial Corporation On January 1, 2023, the Company completed its previously announced acquisition (the “merger”) of PCSB Financial Corporation (“PCSB”). Pursuant to the merger agreement, each share of PCSB common stock outstanding at the effective time of the merger was converted into the right to receive, at the holder’s election, either $22.00 in cash consideration or 1.3284 shares of Company common stock for each share of PCSB common stock, subject to allocation procedures to ensure that 60% of the outstanding shares of PCSB common stock was converted to Company common stock. PCSB’s bank subsidiary, PCSB Bank, operates as a separate subsidiary of the Company and has 15 banking offices throughout the Lower Hudson Valley of New York State. The transaction was accounted for as a business combination. Accordingly, the purchase price was allocated to the assets acquired and liabilities assumed based on their fair values as of the merger effective date. The determination of fair value required management to make estimates about discount rates, future expected cash flows, market conditions, and other future events that are highly subjective in nature and are subject to change. Fair value estimates of the assets acquired and liabilities assumed may be adjusted for a period up to one year (the measurement period) from the closing date of the merger if new information is obtained about facts and circumstances that existed as of the merger effective date that, if known, would have affected the measurement of the amounts recognized as of that date. During the three and six months ended June 30, 2023, the Company incurred merger-related expenses totaling $1.0 million and $7.4 million, respectively. The following table summarizes the preliminary purchase price allocation to the estimated fair value of the assets acquired and liabilities assumed as of the date of the acquisition: Net Assets Acquired at Fair Value (In Thousands) Purchase price consideration $ 297,791 ASSETS Cash 42,373 Investments 366,790 Loans 1,336,737 Allowance for credit losses on PCD loans (2,344) Premises and equipment 14,631 Core deposit and other intangibles 30,265 Other assets 104,654 Total assets acquired $ 1,893,106 LIABILITIES Deposits $ 1,570,563 Borrowings 52,923 Other liabilities 52,624 Total liabilities assumed $ 1,676,110 Net assets acquired 216,996 Goodwill $ 80,795 In connection with the merger, the Company recorded $80.8 million of goodwill, which represents the excess of the purchase price over the fair value of the net assets acquired. Fair values of the major categories of assets acquired and liabilities assumed were determined as follows: Cash and Cash Equivalents The fair values of cash and cash equivalents approximate the respective carrying amounts because the instruments are payable on demand or have short-term maturities. Investments The fair values for investment securities available-for-sale were based on quoted market prices, where available. If quoted market prices were not available, fair value estimates are based on observable inputs, including quoted market prices for similar instruments. Investment securities held-to-maturity were reclassified to investment securities available-for-sale based on the Company's intent at closing. During the six months ended June 30, 2023, the Company restructured the investment portfolio acquired from PCSB. The Company sold approximately 75% of the portfolio which equates to $228.3 million of book value of predominantly longer dated Agency MBS, Agency CMOs, Corporate and Municipal securities. The weighted average duration of these securities was 6.1 years with an average risk weighting of assets of 33%. The Company recognized a $1.7 million gain from selling these securities. Proceeds from the sale and additional cash on hand was used to purchase $295.6 million of short duration securities, the majority of which are US Treasuries, Agency MBS, and a small position of short term Municipal Bond Anticipation Notes. Additional details can be found in Note 3, "Investment Securities". The weighted average duration of these securities was 2.1 years with an average risk weighting of assets of 4%. Loans The fair value of the loan portfolio was calculated on an individual loan basis using discounted cash flow analysis, with results presented and assumptions applied on a summary basis. This analysis took into consideration the contractual terms of the loans and assumptions related to the cost of debt, cost of equity, servicing cost and other liquidity/risk premium considerations to estimate the projected cash flows. The loss rates for the loans were estimated using Probability of Default (cumulative) and Loss Given Default assumptions. The assumptions used in determining the fair value of the loan portfolio were considered reasonable from a market-participant viewpoint. The Company recorded a $49.8 million discount from the results of the loan accounting valuation. Deposits - Core Deposits Intangible ("CDI") Accounts included in the CDI include demand deposits, NOW accounts, money market accounts and savings accounts. The fair value of the CDI was derived from using a financial institution-specific income approach. Factors examined in the valuation of the CDI include customer attrition, deposit interest rates, service charge income, overhead expense, and costs of alternative funding. The Company recorded a $30.3 million CDI from the results of the deposit valuation. The CDI is being amortized at an accelerated rate over 7 years using the sum-of-the-years method. Certificates of Deposits The certificates of deposits were recorded at fair value. The determination of the fair value was calculated using discounted cash flow analysis, which involved present valuing the contractual payments over the remaining life of the certificate of deposit at market based-rates. The Company recorded a $3.2 million discount from the results of the certificate of deposit valuation. Borrowings The fair value of the FHLB advances were ascertained by using discounted cash flow analysis of the contractual payments over the remaining life of the advances at market-based interest rates. The FHLB advances were disaggregated on an individual advance basis and management used FHLB of New York rates as of December 30, 2022 as the market rate in the present value calculation. The Company recorded a $0.3 million discount on the assumed FHLB advances. PCD Loans and Leases Purchased loans and leases that have experienced more-than-insignificant deterioration in credit quality since origination are considered purchase credit deteriorated ("PCD"). For PCD loans and leases, the initial estimate of expected credit losses was established through an adjustment to the unpaid principal balance and non-credit discount at acquisition. The following table reconciles the unpaid principal balance to the fair value of PCD loans and leases: (In Thousands) Total unpaid principal balance $ 16,824 Allowance for credit losses at acquisition (2,344) Non-credit discount (974) Fair value $ 13,506 Supplemental Pro Forma Financial Information The following table summarizes supplemental pro forma financial information giving effect to the merger as if it had been completed on January 1, 2022: Three Months Ended June 30, Six Months Ended June 30, 2023 2022 2023 2022 (In Thousands) Net interest income 86,037 88,366 172,086 170,606 Non-interest income 5,459 8,016 16,695 14,468 Net income 23,445 28,460 47,942 37,648 The supplemental pro forma financial information does not necessarily reflect the results of operations that would have occurred had Brookline Bancorp, Inc. merged with PCSB on January 1, 2022. The supplemental pro forma financial information includes the impact of (i) accreting and amortizing the discounts and premiums associated with the estimated fair value adjustments to acquired loans and leases, investment securities, deposits, and borrowings, (ii) the amortization of recognized intangible assets, (iii) accreting and amortizing the discounts and premiums associated with acquired premises and leases, and (iv) the related estimated income tax effects. Costs savings and other business synergies related to the merger are not included in the supplemental pro forma financial information. In addition, the supplemental pro forma financial information was adjusted to include the $1.0 million and $7.4 million of merger-related expenses recognized during the three and six months ended June 30, 2023, respectively, as summarized in the following table: Three Months Ended June 30, 2023 Six Months Ended June 30, 2023 (In Thousands) Compensation and benefits (1) $ 529 $ 1,750 Technology and equipment (2) 29 1,857 Professional and outside services (3) 364 3,563 Other expense (4) 80 242 Total merger-related expenses $ 1,003 $ 7,413 ______________________________________________________________________ (1) Comprised primarily of severance and employee retention costs. (2) Comprised primarily of technology contract termination fees. (3) Comprised primarily of advisory, legal, accounting, and other professional fees. (4) Comprised primarily of costs of travel and other miscellaneous expenses.

As of June 30, 2023, $862.8 million, or 94.8% of the portfolio, had gross unrealized losses of $80.7 million, compared to $630.5 million, or 96.0% of the portfolio, with gross unrealized losses of $77.5 million as of December 31, 2022. As of June 30, 2023 and December 31, 2022, the Company held no securities as held to maturity; all securities were held as available-for-sale. Investment Securities as Collateral As of June 30, 2023 and December 31, 2022, respectively, $575.0 million and $387.9 million of investment securities were pledged as collateral for repurchase agreements; municipal deposits; treasury, tax and loan deposits; swap agreements; FRB borrowings; and FHLB of Boston and FHLB of New York borrowings. The Banks had no outstanding FRB borrowings as of June 30, 2023 and December 31, 2022. Allowance for Credit Losses-Available-for-Sale Securities For available-for-sale securities in an unrealized loss position, management first assesses whether (i) the Company intends to sell the security, or (ii) it is more likely than not that the Company will be required to sell the security before recovery of its amortized cost basis. If either criterion is met, any previously recognized allowances are charged-off and the security's amortized cost is written down to fair value through income. If neither criterion is met, the security is evaluated to determine whether the decline in fair value has resulted from credit losses or other factors. In making this assessment, management considers the extent to which fair value is less than amortized cost, any changes to the rating of the security by a rating agency and any adverse conditions specifically related to the security, among other factors. If this assessment indicates that a credit loss exists, the present value of cash flows expected to be collected from the security is compared to the amortized cost basis of the security. If the present value of cash flows expected to be collected is less than the amortized cost basis, an allowance for credit loss is recorded, limited by the amount that the fair value is less than the amortized cost basis. Any impairment that has not been recorded through the Allowance for Credit Losses ("ACL") is recognized in other comprehensive income. Adjustments to the allowance are reported as a component of credit loss expense. Available-for-sale securities are charged-off against the allowance or, in the absence of any allowance, written down through income when deemed uncollectible or when either of the aforementioned criteria regarding intent or requirement to sell is met. The Company has made the accounting policy election to exclude accrued interest receivable on available-for-sale securities from the estimate of credit losses. Accrued interest receivables associated with debt securities available-for-sale totaled $4.0 million as of June 30, 2023 compared $2.6 million to as of December 31, 2022. A debt security is placed on nonaccrual status at the time any principal or interest payments become more than 90 days delinquent or if full collection of interest or principal becomes uncertain. Accrued interest for a debt security placed on nonaccrual is reversed against interest income. There were no debt securities on nonaccrual status and therefore there was no accrued interest related to debt securities reversed against interest income for the six months ended June 30, 2023 and 2022. Assessment for Available for Sale Securities for Impairment Investment securities as of June 30, 2023 and December 31, 2022 that have been in a continuous unrealized loss position for less than twelve months or twelve months or longer are as follows: At June 30, 2023 Less than Twelve Months Total Estimated Unrealized Estimated Unrealized Estimated Unrealized (In Thousands) Investment securities available-for-sale: GSE debentures $ 33,040 $ 346 $ 126,061 $ 22,719 $ 159,101 $ 23,065 GSE CMOs 48,240 2,471 16,206 1,735 64,446 4,206 GSE MBSs 47,966 1,021 130,212 18,411 178,178 19,432 Municipal obligations 7,303 247 — — 7,303 247 Corporate debt obligations 15,765 867 13,830 201 29,595 1,068 U.S. Treasury bonds 200,139 2,611 223,570 30,053 423,709 32,664 Foreign government obligations — — 477 23 477 23 Total temporarily impaired investment securities $ 352,453 $ 7,563 $ 510,356 $ 73,142 $ 862,809 $ 80,705 At December 31, 2022 Less than Twelve Months Total Estimated Unrealized Estimated Unrealized Estimated Unrealized (In Thousands) Investment securities available-for-sale: GSE debentures $ 56,719 $ 1,255 $ 95,703 $ 23,076 $ 152,422 $ 24,331 GSE CMOs 16,411 1,563 1,809 192 18,220 1,755 GSE MBSs 97,858 9,823 42,500 9,426 140,358 19,249 Corporate debt obligations 13,764 312 — — 13,764 312 U.S. Treasury bonds 139,103 3,723 166,150 28,100 305,253 31,823 Foreign government obligations 477 23 — — 477 23 Temporarily impaired investment securities available-for-sale 324,332 16,699 306,162 60,794 630,494 77,493 Total temporarily impaired investment securities $ 324,332 $ 16,699 $ 306,162 $ 60,794 $ 630,494 $ 77,493 The Company performs regular analyses of the investment securities available-for-sale portfolio to determine whether a decline in fair value indicates that an investment security is impaired. In making these impairment determinations, management considers, among other factors, projected future cash flows; credit subordination and the creditworthiness; capital adequacy and near-term prospects of the issuers. Management also considers the Company's capital adequacy, interest-rate risk, liquidity and business plans in assessing whether it is more likely than not that the Company will sell or be required to sell the investment securities before recovery. If the Company determines that a security investment is impaired and that it is more likely than not that the Company will not sell or be required to sell the investment security before recovery of its amortized cost, the credit portion of the impairment loss is recognized in the Company's consolidated statement of income and the noncredit portion is recognized in accumulated other comprehensive income. The credit portion of the impairment represents the difference between the amortized cost and the present value of the expected future cash flows of the investment security. If the Company determines that a security is impaired and it is more likely than not that it will sell or be required to sell the investment security before recovery of its amortized cost, the entire difference between the amortized cost and the fair value of the security will be recognized in the Company's consolidated statement of income. Investment Securities Available-For-Sale Impairment Analysis The following discussion summarizes, by investment security type, the basis for evaluating if the applicable investment securities within the Company’s available-for-sale portfolio were impaired as of June 30, 2023. The Company has determined it is more likely than not that the Company will not sell or be required to sell the investment securities before recovery of its amortized cost. The Company's ability and intent to hold these investment securities until recovery is supported by the Company's strong capital and liquidity positions as well as its historically low portfolio turnover. As such, management has determined that the investment securities are not impaired as of June 30, 2023. If market conditions for investment securities worsen or the creditworthiness of the underlying issuers deteriorates, it is possible that the Company may recognize additional impairment in future periods. U.S. Government-Sponsored Enterprises The Company invests in securities issued by U.S. Government-sponsored enterprises ("GSEs"), including GSE debentures, mortgage-backed securities ("MBSs"), and collateralized mortgage obligations ("CMOs"). GSE securities include obligations issued by the Federal National Mortgage Association ("FNMA"), the Federal Home Loan Mortgage Corporation ("FHLMC"), the Government National Mortgage Association ("GNMA"), the FHLB and the Federal Farm Credit Bank. As of June 30, 2023, the Company held GNMA MBSs and CMOs, and Small Business Administration ("SBA") commercial loan asset-backed securities in its available-for-sale portfolio with an estimated fair value of $33.8 million, all of which were backed explicitly by the full faith and credit of the U.S. Government, compared to $2.7 million as of December 31, 2022. As of June 30, 2023, the Company owned 41 GSE debentures with a total fair value of $166.0 million, and a net unrealized loss of $23.1 million. The acquisition of PCSB accounted for $40.0 million of the total fair value at June 30, 2023.

During the six months ended June 30, 2023 and 2022, the Company did not purchase GSE debentures. As of June 30, 2023, the Company owned 60 GSE CMOs with a total fair value of $64.4 million and a net unrealized loss of $4.2 million. The acquisition of PCSB accounted for $48.2 million of the total fair value at June 30, 2023. As of December 31, 2022, the Company held 32 GSE CMOs with a total fair value of $18.2 million with a net unrealized loss of $1.8 million. As of June 30, 2023 and December 31, 2022 , all of the securities in this portfolio were in an unrealized loss position. All securities are performing and backed by the implicit (FHLB/FNMA/FHLMC) or explicit (GNMA) guarantee of the U.S Government. During the six months ended June 30, 2023 and 2022, the Company did not purchase any GSE CMOs. As of June 30, 2023, the Company owned 150 GSE MBSs with a total fair value of $179.7 million and a net unrealized loss of $19.4 million. The acquisition of PCSB accounted for $48.6 million of the total fair value at June 30, 2023. As of December 31, 2022, the Company held 134 GSE MBSs with a total fair value of $140.6 million with a net unrealized loss of $19.2 million. As of June 30, 2023, 143 of the 150 securities in this portfolio were in an unrealized loss position. As of December 31, 2022, 128 of the 134 securities in this portfolio were in an unrealized loss position. All securities are performing and backed by the implicit (FHLB/FNMA/FHLMC) or explicit (GNMA) guarantee of the U.S Government. During the six months ended June 30, 2023 the Company purchased $39.4 million of GSE MBSs compared to the same period in 2022 when the Company did not purchase any GSE MBSs. Municipal Obligations The Company invests in certain state and municipal securities with high credit ratings for portfolio diversification and tax planning purposes. As of June 30, 2023, the Company owned 47 municipal obligation securities with a total fair value of $15.6 million which approximates cost. The acquisition of PCSB, and purchases year to date accounted for all of the total fair value at June 30, 2023. As of December 31, 2022, the Company did not hold any municipal securities. As of June 30, 2023,12 of the 47 securities in this portfolio were in an unrealized loss position. During the six months ended June 30, 2023, the Company purchased $5.6 million of municipal securities compared to the same period in 2022 when the Company did not purchase any municipal securities. Corporate Obligations The Company may invest in high-quality corporate obligations to provide portfolio diversification and improve the overall yield on the portfolio. As of June 30, 2023, the Company held 13 corporate obligation securities with a total fair value of $31.9 million and a net unrealized loss of $1.1 million. The acquisition of PCSB accounted for $18.1 million of the total fair value at June 30, 2023.

As of December 31, 2022, all of the securities in this portfolio were in an unrealized loss position. Full collection of the obligations is expected because the financial condition of the issuers is sound, they have not defaulted on scheduled payments, the obligations are rated investment grade, and the Company has the ability and intent to hold the obligations for a period of time to recover the amortized cost. During the six months ended June 30, 2023 and 2022, the Company did not purchase any corporate obligations. U.S. Treasury Bonds The Company invests in securities issued by the U.S. government.

Additions to the allowance for credit losses are made by charges to the provision for credit losses. Losses on loans and leases are charged off against the allowance when all or a portion of a loan or lease is considered uncollectible. Subsequent recoveries on loans previously charged off, if any, are credited to the allowance when realized. To calculate the allowance for loans collectively evaluated, management uses models developed by a third party. Commercial real estate ("CRE"), commercial and industrial ("C&I"), and retail lifetime loss rate models calculate the expected losses over the life of the loan based on exposure at default loan attributes and reasonable, supportable economic forecasts. The exposure at default considers the current unpaid balance, prepayment assumptions and expected utilization assumptions. The expected loss estimates for two small commercial portfolios are based on historical loss rates. Key assumptions used in the models include portfolio segmentation, prepayments, and the expected utilization of unfunded commitments, among others. The portfolios are segmented by loan level attributes such as loan type, loan size, date of origination, and delinquency status to create homogenous loan pools. Pool level metrics are calculated and loss rates are subsequently applied to the pools as the loans have like characteristics. Prepayment assumptions are embedded within the models and are based on the same data used for model development and incorporate adjustments for reasonable and supportable forecasts. Model development data and developmental time periods vary by model, but all use at least ten years of historical data and capture at least one recessionary period. Expected utilization is based on current utilization and a loan equivalency ("LEQ") factor. LEQ varies by current utilization and provides a reasonable estimate of expected draws and borrower behavior. Assumptions and model inputs are reviewed in accordance with model monitoring practices and as information becomes available . The ACL estimate incorporates reasonable and supportable forecasts of various macro-economic variables over the remaining life of loans and leases. The development of the reasonable and supportable forecast assume each macro-economic variable will revert to long-term expectations, with reversion characteristics unique to specific economic indicators and forecasts. Reversion towards long-term expectations generally begins two Management elected to use multiple economic forecasts in determining the reserve to account for economic uncertainty. The forecasts include various projections of gross domestic product ("GDP"), interest rates, property price indices, and employment measures. Scenario weighting and model parameters are reviewed for each calculation and updated to reflect facts and circumstances as of the financial statement date. The forecasts utilized at June 30, 2023 reflect the immediate and longer-term effects of a rising interest rate environment and inflationary conditions. As of June 30, 2023, management applied qualitative adjustments to the CRE lifetime loss rate, C&I lifetime loss rate, and Retail lifetime loss rate models. These adjustments addressed model limitations, were based on historical loss patterns, and targeted specific risks within the certain portfolios. A general qualitative adjustment was applied to all models to account for general economic uncertainty by placing a greater probability on negative economic forecasts. Additional qualitative adjustments were applied to the commercial, multifamily, and commercial real estate (includes owner occupied, non-owner occupied, and construction) portfolios based on the Company’s historical loss experience and the loss experience of the Company’s peer group. High risk segments of the Eastern Funding portfolios also received additional qualitative adjustments based on recent loss history and expected liquidation values. These qualitative adjustments resulted in additions to reserves for all portfolios, as compared to the model output. Specific reserves are established for loans individually evaluated for impairment when amortized cost basis is greater than the discounted present value of expected future cash flows or, in the case of collateral-dependent loans, when there is an excess of a loan's amortized cost basis over the fair value of its underlying collateral. When loans and leases do not share risk characteristics with other financial assets they are evaluated individually. Individually evaluated loans are reviewed quarterly with adjustments made to the calculated reserve as necessary. The general allowance for loan and lease losses was $111.0 million as of June 30, 2023, compared to $95.4 million as of December 31, 2022. The increase in the general allowance was primarily driven by the acquisition of PCSB Bank during the year, which contributed $14.8 million of the $15.6 million increase, and secondarily by loan growth during the year. The specific allowance for loan and lease losses was $14.8 million as of June 30, 2023, compared to $3.1 million as of December 31, 2022. The specific allowance increased by $11.7 million during the six months ended June 30, 2023 primarily due to specific reserves on two C&I accounts totaling $6 million, as well as specific reserve increases totaling $2.9 million for commercial real estate loans and $2.2 million in equipment financing loans. As of June 30, 2023, management believes that the methodology for calculating the allowance is sound and that the allowance provides a reasonable basis for determining and reporting on expected losses over the lifetime of the Company’s loan portfolios. Credit Quality Assessment At the time of loan origination, a rating is assigned based on the capacity to pay and general financial strength of the borrower, the value of assets pledged as collateral, and the evaluation of third party support such as a guarantor. The Company continually monitors the credit quality of the loan portfolio using all available information. The officer responsible for handling each loan is required to initiate changes to risk ratings when changes in facts and circumstances occur that warrant an upgrade or downgrade in a loan rating. Based on this information, loans demonstrating certain payment issues or other weaknesses may be categorized as delinquent, adversely risk-rated, nonperforming and/or put on nonaccrual status. Additionally, in the course of resolving such loans, the Company may choose to restructure the contractual terms of certain loans to match the borrower's ability to repay the loan based on their current financial condition. If a restructured loan meets certain criteria, it may be categorized as a modified loan. The Company reviews numerous credit quality indicators when assessing the risk in its loan portfolio. For all loans, the Company utilizes an eight-grade loan rating system, which assigns a risk rating to each borrower based on a number of quantitative and qualitative factors associated with a loan transaction. Factors considered include industry and market conditions; position within the industry; earnings trends; operating cash flow; asset/liability values; debt capacity; guarantor strength; management and controls; financial reporting; collateral; and other considerations. In addition, the Company's independent loan review group evaluates the credit quality and related risk ratings in all loan portfolios. The results of these reviews are reported to the Risk Committee of the Board of Directors on a periodic basis and annually to the Board of Directors. For the consumer loans, the Company heavily relies on payment status for calibrating credit risk. The ratings categories used for assessing credit risk in the commercial real estate, multi-family mortgage, construction, commercial, equipment financing, condominium association and other consumer loan and lease classes are defined as follows: 1 -4 Rating—Pass Loan rating grades "1" through "4" are classified as "Pass," which indicates borrowers are performing in accordance with the terms of the loan and are less likely to result in loss due to the capacity of the borrower to pay and the adequacy of the value of assets pledged as collateral. 5 Rating—Other Assets Especially Mentioned ("OAEM") Borrowers exhibit potential credit weaknesses or downward trends deserving management's attention. If not checked or corrected, these trends will weaken the Company's asset and position. While potentially weak, currently these borrowers are marginally acceptable; no loss of principal or interest is envisioned. 6 Rating—Substandard Borrowers exhibit well defined weaknesses that jeopardize the orderly liquidation of debt. Substandard loans may be inadequately protected by the current net worth and paying capacity of the obligors or by the collateral pledged, if any. Normal repayment from the borrower is in jeopardy. Although no loss of principal is envisioned, there is a distinct possibility that a partial loss of interest and/or principal will occur if the deficiencies are not corrected. Collateral coverage may be inadequate to cover the principal obligation. 7 Rating—Doubtful Borrowers exhibit well-defined weaknesses that jeopardize the orderly liquidation of debt with the added provision that the weaknesses make collection of the debt in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable. Serious problems exist to the point where partial loss of principal is likely. 8 Rating—Definite Loss Borrowers deemed incapable of repayment. Loans to such borrowers are considered uncollectible and of such little value that continuation as active assets of the Company is not warranted. Assets rated as "OAEM," "substandard" or "doubtful" based on criteria established under banking regulations are collectively referred to as "criticized" assets.

The loans and leases risk-rated "substandard" or worse are considered impaired. The Company has also defined the population of impaired loans to include nonaccrual loans and modified loans. Impaired loans and leases which do not share similar risk characteristics with other loans are individually evaluated for credit losses. Specific reserves are established for loans and leases with deterioration in the present value of expected future cash flows or, in the case of collateral-dependent loans and leases, any increase in the loan or lease amortized cost basis over the fair value of the underlying collateral discounted for estimated selling costs. In contrast, the loans and leases which share similar risk characteristics and are not included in the individually evaluated population are collectively evaluated for credit losses. The following tables present information regarding individually evaluated and collectively evaluated allowance for loan and lease losses for credit losses on loans and leases at the dates indicated.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives and Hedging Activities	Derivatives and Hedging Activities The Company executes loan level derivative products such as interest rate swap agreements with commercial banking customers to aid them in managing their interest rate risk. The interest rate swap contracts allow the commercial banking customers to convert floating rate loan payments to fixed rate loan payments. The Company concurrently enters into offsetting swaps with a third party financial institution, effectively minimizing its net risk exposure resulting from such transactions. The third party financial institution exchanges the customer's fixed rate loan payments for floating rate loan payments. As the interest rate swap agreements associated with this program do not meet hedge accounting requirements, changes in the fair value are recognized directly in earnings. Based on the Company's intended use for the loan level derivatives at inception, the Company designates the derivative as either an economic hedge of an asset or liability, or a hedging instrument subject to the hedge accounting provisions of FASB ASC Topic 815, "Derivatives and Hedging". The Company believes using interest rate derivatives adds stability to interest income and expense and allows the Company to manage its exposure to interest rate movements. The Company enters into interest rate swaps as part of its interest rate risk management strategy. These interest rate swaps are designated as cash flow hedges and involve the receipt of variable rate amounts from a counterparty in exchange for the Company making fixed payments. The Company enters into interest rate swaps as hedging instruments against the interest rate risk associated with the Company's FHLB borrowings and loan portfolio. For derivative instruments that are designated and qualify as cash flow hedging instruments, the effective portion of the gains or losses is reported as a component of other comprehensive income ("OCI"), and is reclassified into earnings in the period that the hedged forecasted transaction affects earnings. The following table reflects the Company's derivative positions as of the date indicated below for interest rate derivatives which qualify as cash flow hedges for accounts purposes. At June 30, 2023 Notional Amount Average Maturity Weighted Average Rate Fair Value Current Rate Paid Received Fixed Swap Rate (in thousands) (in years) (in thousands) Interest rate swaps on loans $ 225,000 3.40 5.07 % 3.39 % $ (5,842) At December 31, 2022 Notional Amount Average Maturity Weighted Average Rate Fair Value Current Rate Paid Received Fixed Swap Rate (in thousands) (in years) (in thousands) Interest rate swaps on loans $ 150,000 3.77 4.11 % 3.26 % $ (3,030) The Company utilizes risk participation agreements with other banks participating in commercial loan arrangements. Participating banks guarantee the performance on borrower-related interest rate swap contracts. Risk participation agreements are derivative financial instruments and are recorded at fair value. These derivatives are not designated as hedges and therefore, changes in fair value are recorded directly through earnings in other non-interest income at each reporting period. Under a risk participation-out agreement, a derivative asset, the Company participates out a portion of the credit risk associated with the interest rate swap position executed with the commercial borrower, for a fee paid to the participating bank. The Company offers foreign exchange contracts to commercial borrowers to accommodate their business needs. These foreign exchange contracts do not qualify as hedges for accounting purposes. To mitigate the market and liquidity risk associated with these foreign exchange contracts, the Company enters into similar offsetting positions. Asset derivatives and liability derivatives are included in other assets and accrued expenses and other liabilities on the unaudited consolidated balance sheets. The following tables present the Company's customer related derivative positions for the periods indicated below for those derivatives not designated as hedging.

A portion of the balance reported in accumulated other comprehensive income related to derivatives will be reclassified to interest expense as interest payments are made or received on the Company’s interest rate swaps. The Company monitors the risk of counterparty default on an ongoing basis.

Stock Based Compensation	Stock Based Compensation As of June 30, 2023, the Company had one active equity plan: the Brookline Bancorp, Inc. 2021 Stock Option and Incentive Plan ("2021 Plan"). As a result of the 2021 Plan having been approved by the Company's stockholders at the 2021 annual meeting of stockholders, the Company discontinued granting awards under the Brookline Bancorp, Inc. 2014 Equity Incentive Plan (the "2014 Plan"), and no further shares will be granted as awards under the 2014 Plan. The Brookline Bancorp, Inc. 2011 Restricted Stock Plan (the "2011 Plan") expired in July 2021, and the Company has not issued shares from the 2011 Plan since the adoption of the 2014 Plan. The 2021 Plan and the 2014 Plan are together referred to as the "Plans." Of the awarded shares under the Plans, generally 50% vest ratably over three years with one-third of such shares vesting at each of the first, second and third anniversary dates of the awards. These are referred to as "time-based shares". The remaining 50% of each award will vest three years after the award date based on the level of the Company's achievement of identified performance targets in comparison to the level of achievement of such identified performance targets by a defined peer group. These are referred to as "performance-based shares". If a participant leaves the Company prior to the third anniversary date of an award, any unvested shares are usually forfeited. Dividends declared with respect to shares awarded will be held by the Company and paid to the participant only when the shares vest. Under the Plans, shares of the Company's common stock are reserved for issuance as restricted stock awards to officers, employees, and non-employee directors of the Company. Shares issued upon vesting may be either authorized but unissued shares or reacquired shares held by the Company as treasury shares. Any shares not issued because vesting requirements are not met will be retired back to treasury and be made available again for issuance under the Plans. During the three and six months ended June 30, 2023 and June 30, 2022, no shares were issued, respectively, upon satisfaction of required conditions of the Plans. Total expense for the Plans was $0.9 million and $0.8 million for the three months ended June 30, 2023 and 2022, respectively. Total expense for the Plan was $1.8 million and $1.6 million for the six months ended June 30, 2023 and 2022, respectively.

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	Fair Value of Financial InstrumentsA description of the valuation methodologies used for assets and liabilities measured at fair value on a recurring and non-recurring basis, as well as the general classification of such instruments pursuant to the valuation hierarchy, is set forth below. There were no changes in the valuation techniques used during the three and six months ended June 30, 2023 and June 30, 2022. Assets and Liabilities Recorded at Fair Value on a Recurring Basis The following tables set forth the carrying value of assets and liabilities measured at fair value on a recurring basis at the dates indicated: Carrying Value as of June 30, 2023 Level 1 Level 2 Level 3 Total (In Thousands) Assets: Investment securities available-for-sale: GSE debentures $ — $ 166,018 $ — $ 166,018 GSE CMOs — 64,446 — 64,446 GSE MBSs — 179,659 — 179,659 Municipal obligations — 3,280 12,334 15,614 Corporate debt obligations — 24,630 7,268 31,898 U.S. Treasury bonds — 452,098 — 452,098 Foreign government obligations — 477 — 477 Total investment securities available-for-sale $ — $ 890,608 $ 19,602 $ 910,210 Assets: Interest rate derivatives — — — — Derivatives not designated as hedging instruments: Loan level derivatives — 126,985 — 126,985 Risk participation-out agreements — 1,561 — 1,561 Foreign exchange contracts — 415 — 415 Liabilities: Interest rate derivatives $ — $ 5,842 $ — $ 5,842 Derivatives not designated as hedging instruments: Loan level derivatives — 126,985 — 126,985 Risk participation-in agreements — 22 — 22 Foreign exchange contracts — 398 — 398 Carrying Value as of December 31, 2022 Level 1 Level 2 Level 3 Total (In Thousands) Assets: Investment securities available-for-sale: GSE debentures $ — $ 152,422 $ — $ 152,422 GSE CMOs — 18,220 — 18,220 GSE MBSs — 140,576 — 140,576 Corporate debt obligations — 13,764 — 13,764 U.S. Treasury bonds — 331,307 — 331,307 Foreign government obligations — 477 — 477 Total investment securities available-for-sale $ — $ 656,766 $ — $ 656,766 Interest rate derivatives — 34 — 34 Loan level derivatives — 108,963 — 108,963 Risk participation-out agreements — 347 — 347 Foreign exchange contracts — 130 — 130 Liabilities: Interest rate derivatives $ — $ 3,170 $ — $ 3,170 Loan level derivatives — 108,963 — 108,963 Risk participation-in agreements — 31 — 31 Foreign exchange contracts — 112 — 112 Investment Securities Available-for-Sale The fair value of investment securities is based principally on market prices and dealer quotes received from third-party and nationally-recognized pricing services for identical investment securities such as U.S. Treasury and agency securities. These prices are validated by comparing the primary pricing source with an alternative pricing source when available. When quoted market prices for identical securities are unavailable, the Company uses market prices provided by independent pricing services based on recent trading activity and other observable information, including but not limited to market interest-rate curves, referenced credit spreads and estimated prepayment speeds, where applicable. These investments include GSE debentures, GSE mortgage-related securities, SBA commercial loan asset backed securities, corporate debt obligations, municipal obligations and trust preferred securities, all of which are included in Level 2. As of June 30, 2023, $19.6 million of investment securities available-for-sale are included in Level 3 within the investment portfolio. The composition of these assets are primarily composed of subordinated debt of local banks and private placement municipal securities. Of these securities, approximately $14.6 million are private placement municipal Bond Anticipation Notes. As of December 31, 2022, none of the investment securities were valued using pricing models included in Level 3. Additionally, management reviews changes in fair value from period to period and performs testing to ensure that prices received from the third parties are consistent with management's expectation of the market. Changes in the prices obtained from the pricing service are analyzed from month to month, taking into consideration changes in market conditions including changes in mortgage spreads, changes in U.S. Treasury security yields and changes in generic pricing of 15-year and 30-year securities. Additional analysis may include a review of prices provided by other independent parties, a yield analysis, a review of average life changes using Bloomberg analytics and a review of historical pricing for a particular security. Derivatives and Hedging Instruments The fair value of interest rate derivatives designated as hedging instruments, loan level derivatives, risk participation agreements (RPA in/out), and foreign exchange contracts represent a Level 2 valuation and are based on settlement values adjusted for credit risks associated with the counterparties and the Company and observable market interest rate curves and foreign exchange rates where applicable. Credit risk adjustments consider factors such as the likelihood of default by the Company and its counterparties, its net exposures and remaining contractual life. To date, the Company has not realized any losses due to a counterparty's inability to pay any net uncollateralized position. Refer also to Note 8, "Derivatives and Hedging Activities." There were no transfers between levels for assets and liabilities recorded at fair value on a recurring basis at June 30, 2023 and December 31, 2022, respectively. The following tables summarize information about significant unobservable inputs related to the Company's categories of Level 3 financial assets and liabilities measured on a recurring basis.

Other Real Estate Owned ("OREO") The Company records OREO at the lower of cost or fair value. In estimating fair value, the Company utilizes purchase and sales agreements (Level 2) or comparable sales, recent appraisals or cash flows discounted at an interest rate commensurate with the risk associated with these cash flows (Level 3), adjusted for selling costs and other expenses. As of June 30, 2023 and December 31, 2022, the Company did not record any OREO. Repossessed Assets Repossessed assets are carried at estimated fair value less costs to sell based on auction pricing (Level 2). The table below presents quantitative information about significant unobservable inputs (Level 3) for assets measured at fair value on a non-recurring basis at the dates indicated. Fair Value Valuation Technique At June 30, At December 31, 2022 (Dollars in Thousands) Collateral-dependent impaired loans and leases $ 7,737 $ 779 Appraisal of collateral (1) ________________________________________________________________________ (1) Fair value is generally determined through independent appraisals of the underlying collateral. The Company may also use another available source of collateral assessment to determine a reasonable estimate of the fair value of the collateral. Appraisals may be adjusted by management for qualitative factors such as economic factors and estimated liquidation expenses. The range of the unobservable inputs used may vary but is generally 0% - 10% on the discount for costs to sell and 0% - 15% on appraisal adjustments. Summary of Estimated Fair Values of Financial Instruments The following table presents the carrying amount, estimated fair value, and placement in the fair value hierarchy of the Company's financial instruments at the dates indicated. This table excludes financial instruments for which the carrying amount approximates fair value. Financial assets for which the fair value approximates carrying value include cash and cash equivalents, restricted equity securities, and accrued interest receivable. Financial liabilities for which the fair value approximates carrying value include non-maturity deposits, short-term borrowings, and accrued interest payable.

These categories were further disaggregated based upon significant financial characteristics such as type of interest rate (fixed / variable) and payment status (current / past-due). Using the exit price valuation method, the Company discounts the contractual cash flows for each loan category using interest rates currently being offered for loans with similar terms to borrowers of similar quality and incorporates estimates of future loan prepayments. Deposits The fair values of deposit liabilities with no stated maturity (demand, NOW, savings and money market savings accounts) are equal to the carrying amounts payable on demand. The fair value of certificates of deposit represents contractual cash flows discounted using interest rates currently offered on deposits with similar characteristics and remaining maturities. The fair value estimates for deposits do not include the benefit that results from the low-cost funding provided by the Company's core deposit relationships (deposit-based intangibles). Borrowed Funds The fair value of federal funds purchased is equal to the amount borrowed. The fair value of FHLB advances and repurchase agreements represents contractual repayments discounted using interest rates currently available for borrowings with similar characteristics and remaining maturities. The fair values reported for retail repurchase agreements are based on the discounted value of contractual cash flows. The discount rates used are representative of approximate rates currently offered on borrowings with similar characteristics and maturities. The fair values reported for subordinated deferrable interest debentures are based on the discounted value of contractual cash flows. The discount rates used are representative of approximate rates currently offered on instruments with similar terms and maturities.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Off-Balance Sheet Financial Instruments The Company is party to off-balance sheet financial instruments in the normal course of business to meet the financing needs of its customers and to reduce its own exposure to fluctuations in interest rates. These financial instruments include loan commitments, standby and commercial letters of credit, and loan level derivatives. According to GAAP, these financial instruments are not recorded in the financial statements until they are funded or related fees are incurred or received. The contract amounts reflect the extent of the involvement the Company has in particular classes of these instruments. Such commitments involve, to varying degrees, elements of credit risk and interest-rate risk in excess of the amount recognized in the consolidated balance sheets. The Company's exposure to credit loss in the event of non-performance by the counterparty is represented by the fair value of the instruments. The Company uses the same policies in making commitments and conditional obligations as it does for on-balance sheet instruments. Financial instruments with off-balance-sheet risk at the dates indicated follow: At June 30, 2023 At December 31, 2022 (In Thousands) Financial instruments whose contract amounts represent credit risk: Commitments to originate loans and leases: Commercial real estate $ 125,226 $ 414,217 Commercial 245,667 291,188 Residential mortgage 16,317 14,036 Unadvanced portion of loans and leases 1,311,073 1,202,738 Unused lines of credit: Home equity 756,009 700,201 Other consumer 113,817 97,313 Other commercial 511 526 Unused letters of credit: Financial standby letters of credit 14,611 13,584 Performance standby letters of credit 29,434 31,330 Commercial and similar letters of credit 4,817 2,619 Interest rate derivatives 225,000 150,000 Loan level derivatives (Notional principal amounts): Receive fixed, pay variable 1,762,448 1,489,709 Pay fixed, receive variable 1,762,448 1,489,709 Risk participation-out agreements 510,611 393,624 Risk participation-in agreements 74,297 75,223 Foreign exchange contracts (Notional amounts): Buys foreign currency, sells U.S. currency 2,283 2,383 Sells foreign currency, buys U.S. currency 2,300 2,400 Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require the payment of a fee by the customer. Since some of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. The Company evaluates each customer's creditworthiness on a case-by-case basis. The amount of collateral obtained, if any, is based on management's credit evaluation of the borrower. Standby and commercial letters of credit are conditional commitments issued by the Company to guarantee performance of a customer to a third party. These standby and commercial letters of credit are primarily issued to support the financing needs of the Company's commercial customers. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loans to customers. From time to time, the Company enters into loan level derivatives, risk participation agreements or foreign exchange contracts with commercial customers and third-party financial institutions. These derivatives allow the Company to offer long-term fixed-rate commercial loans while mitigating the interest-rate or foreign exchange risk of holding those loans. In a loan level derivative transaction, the Company lends to a commercial customer on a floating-rate basis and then enters into a loan level derivative with that customer. Concurrently, the Company enters into offsetting swaps with a third-party financial institution, effectively minimizing its net interest-rate risk exposure resulting from such transactions. The fair value of these derivatives are presented in Note 8. Lease Commitments The Company leases certain office space under various noncancellable operating leases as well as certain other assets. These leases have original terms ranging from 1 year to over 25 years. Certain leases contain renewal options and escalation clauses which can increase rental expenses based principally on the consumer price index and fair market rental value provisions. All of the Company's current outstanding leases are classified as operating leases. The Company considered the following criteria when determining whether a contract contains a lease, the existence of an identifiable asset and the right to obtain substantially all of the economic benefits from use of the asset through the period. The Company uses the FHLB classic advance rates available as of the lease's start dates as the discount rate to determine the net present value of the remaining lease payments. Total lease commitments increased from $19.5 million as of December 31, 2022 to $33.0 million as of June 30, 2023. The increase is due to the addition of 12 leases for PCSB Bank branch locations.

Revenue from Contract with Customer [Abstract]
Revenue from Contracts with Customers	Revenue from Contracts with Customers Overview Revenue from contracts with customers in the scope of ASC 606 ("Topic 606") is measured based on the consideration specified in the contract with a customer and excludes amounts collected on behalf of third parties. The Company recognizes revenue from contracts with customers when it satisfies its performance obligations. The Company’s performance obligations are generally satisfied as services are rendered and can either be satisfied at a point in time or over time. Unsatisfied performance obligations at the report date are not material to our consolidated financial statements. In certain cases, other parties are involved with providing services to our customers. If the Company is a principal in the transaction (providing services itself or through a third party on its behalf), revenues are reported based on the gross consideration received from the customer and any related expenses are reported in gross noninterest expense. If the Company is an agent in the transaction (referring to another party to provide services), the Company reports its net fee or commission retained as revenue. A substantial portion of the Company’s revenue is specifically excluded from the scope of Topic 606. This exclusion is associated with financial instruments, including interest income on loans and investment securities, in addition to loan derivative income and gains on loan and investment sales. For the revenue that is in-scope of Topic 606, the following is a description of principal activities from which the Company generates its revenue from contracts with customers, separated by the timing of revenue recognition. Revenue Recognized at a Point in Time The Company recognizes revenue that is transactional in nature and such revenue is earned at a point in time. Revenue that is recognized at a point in time includes card interchange fees (fee income related to debit card transactions), ATM fees, wire transfer fees, overdraft charge fees, and stop-payment and returned check fees. Additionally, revenue is collected from loan fees, such as letters of credit, line renewal fees and application fees. Such revenue is derived from transactional information and is recognized as revenue immediately as the transactions occur or upon providing the service to complete the customer’s transaction. Revenue Recognized Over Time The Company recognizes revenue over a period of time, generally monthly, as services are performed and performance obligations are satisfied. Such revenue includes commissions on investments, insurance sales and service charges on deposit accounts. Fee revenue from service charges on deposit accounts represents the service charges assessed to customers who hold deposit accounts at the Banks.

Accounting Policies
Basis of Financial Statement Presentation	Basis of Financial Statement PresentationThe unaudited consolidated financial statements of the Company presented herein have been prepared pursuant to the rules of the SEC for quarterly reports on Form 10-Q and do not include all of the information and note disclosures required by U.S. generally accepted accounting principles (“GAAP”). In the opinion of management, all adjustments (consisting of normal recurring adjustments) and disclosures considered necessary for the fair presentation of the accompanying consolidated financial statements have been included. Interim results are not necessarily reflective of the results of the entire year. The accompanying unaudited consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Annual Report on Form 10-K for the fiscal year ended December 31, 2022.
Consolidation	The unaudited consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All significant intercompany transactions and balances are eliminated in consolidation.
Use of Estimates	In preparing these consolidated financial statements, management is required to make significant estimates and assumptions that affect the reported amounts of assets, liabilities, income, expenses and disclosure of contingent assets and liabilities. Actual results could differ from those estimates based upon changing conditions, including economic conditions and future events. Material estimates that are particularly susceptible to significant changes in the near-term include the determination of the allowance for credit losses, the determination of fair market values of acquired assets and liabilities, including acquired loans, the review of goodwill and intangible assets for impairment and the review of deferred tax assets for valuation allowances. The judgments used by management in applying these critical accounting policies may be affected by a further and prolonged deterioration in the economic environment, which may result in changes to future financial results. For example, subsequent evaluations of the loan and lease portfolio, in light of the factors then prevailing, may result in significant changes in the allowance for loan and lease losses in future periods, and the inability to collect outstanding principal may result in increased loan and lease losses.
Reclassification	ReclassificationCertain previously reported amounts have been reclassified to conform to the current year's presentation.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In March 2020, the FASB issued ASU 2020-04, "Reference Rate Reform (Topic 848)-Facilitation of the Effects of Reference Rate Reform on Financial Reporting" ("ASU 2020-04") to provide optional expedients and exceptions for applying GAAP to certain contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. The amendments in this update apply only to contracts, hedging relationships, and other transactions that reference the London Interbank Offered Rate ("LIBOR") or another reference rate expected to be discontinued because of reference rate reform. The expedients and exceptions provided by the amendments do not apply to contract modifications made and hedging relationships existing as of December 31, 2022, for which an entity has elected certain optional expedients provided that those elections are retained through the end of the hedging relationship. The amendments in this update are effective for all entities as of March 12, 2020 through December 31, 2022 and do not apply to contract modifications made after December 31, 2022. In January 2021, FASB issued ASU 2021-01, "Reference Rate Reform (Topic 848)" an update to address concerns around structural risk of interbank offered rates ("IBORs"), particularly, the risk of cessation of the LIBOR. The amendments in this update clarify that certain optional expedients and exceptions in Topic 848 for contract modifications and hedge accounting apply to derivatives that are affected by the discounting transition. In December 2022, FASB issued ASU 2022-06, "Reference Rate Reform (Topic 848)" which deferred the sunset date of Topic 848 to December 31, 2024, to allow for a transition period after the sunset of LIBOR. The Company has adopted the amendments in these updates and established a LIBOR transition committee to guide the Company’s transition from LIBOR. The Company has completed much of the work to transition off the LIBOR index consistent with industry timelines. The working group has identified its products that utilize LIBOR and has implemented fallback language to facilitate the transition to alternative rates. The Company has also evaluated its infrastructure and identified fallback rates as well as started offering alternative indices and new products tied to these alternative indices. The Company does not anticipate the adoption of these standards to have a material impact to the consolidated financial statements. In October 2021, the FASB issued ASU 2021-08, "Business Combinations (Topic 805), Accounting for Contract Assets and Contract Liabilities from Contracts with Customers" which requires that an acquirer recognize and measure contract assets and contract liabilities acquired in a business combination in accordance with Topic 606, Revenue from Contracts with Customers. At the acquisition date, an acquirer should account for the related revenue contracts in accordance with Topic 606 as if it had originated the contracts. The Company adopted ASU 2021-08 as of January 1, 2023 on a prospective basis. The adoption did not have a material impact on the Company's consolidated financial statements.
