Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Financial Statement Presentation	Basis of Financial Statement Presentation The accompanying consolidated financial statements include the accounts of Columbia Financial, Inc. ("Columbia Financial"), its wholly-owned subsidiaries, Columbia Bank ("Columbia") and Freehold Bank ("Freehold") and Columbia's wholly-owned subsidiaries, Columbia Investment Services, Inc., 2500 Broadway Corp., 1901 Residential Management Co. LLC, First Jersey Title Services, Inc., 1901 Commercial Management Co. LLC, Stewardship Realty LLC, CSB Realty Corp., and RSI Insurance Agency, Inc., (collectively, the “Company”). In consolidation, all intercompany accounts and transactions are eliminated. Columbia Financial, Inc. is a majority-owned subsidiary of Columbia Bank, MHC (the "MHC"). The accounts of the MHC are not consolidated in the accompanying consolidated financial statements of the Company. In preparing the interim unaudited consolidated financial statements, management is required to make estimates, significant judgments and assumptions that affect the reported amounts of assets and liabilities as of the dates of the Consolidated Statements of Financial Condition and Consolidated Statements of Income for the periods presented. Actual results could differ from these judgments and estimates under different conditions, resulting in a change that could have a material impact on the carrying values of our assets and liabilities and our results of operations. Material estimates that involve significant judgments and assumptions that are particularly susceptible to change are the determination of the adequacy of the allowance for credit losses, evaluation of the need for valuation allowances on deferred tax assets, and determination of liabilities related to retirement and other post-retirement benefits. These estimates, significant judgments and assumptions are evaluated on an ongoing basis and are adjusted when facts and circumstances dictate. The interim unaudited 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 six month periods ended June 30, 2023 are not necessarily indicative of the results of operations that may be expected for the entire fiscal year or any other period. The interim unaudited consolidated financial statements of the Company presented herein have been prepared in accordance with the rules of the Securities and Exchange Commission (“SEC”) for quarterly reports on Form 10-Q and U.S. generally accepted accounting principles (“GAAP”). Certain information and note disclosures have been condensed or omitted pursuant to the rules and regulations of the SEC.

Business Combination and Asset Acquisition [Abstract]
Acquisitions	Acquisitions Freehold Bank On December 1, 2021, the Company completed its acquisition of Freehold Bancorp, MHC, Freehold Bancorp, Inc. and Freehold Bank (collectively, the "Freehold Entities" or "Freehold"). Pursuant to the terms of the merger agreement, Freehold Bancorp, MHC merged with and into the MHC, with the MHC as the surviving entity; and Freehold Bancorp, Inc. merged with and into Columbia Financial, with Columbia Financial as the surviving entity. In connection with the merger, Freehold Bank converted to a federal savings bank and will operate as a wholly-owned subsidiary of Columbia Financial until November 6, 2023, the effective date of the merger of Freehold Bank into Columbia Bank. Under the terms of the merger agreement, depositors of Freehold Bank became depositors of Columbia Bank and have the same rights and privileges in the MHC as if their accounts had been established at Columbia Bank on the date established at Freehold Bank. The Company issued 2,591,007 shares of its common stock to the MHC, representing an amount equal to the fair value of the Freehold Entities as determined by an independent appraiser, at the effective time of the holding company mergers. Merger-related expenses are recorded in the Consolidated Statements of Income and are expensed as incurred. Direct acquisition and other charges incurred in connection with the acquisition of the Freehold Entities totaled $73,866 during both the three and six months ended June 30, 2023, and $7,000 during both the three and six months ended June 30, 2022. 2. Acquisitions (continued) RSI Bank On May 1, 2022, the Company completed its acquisition of RSI Bancorp, M.H.C., RSI Bancorp, Inc. and RSI Bank (collectively, the “RSI Entities” or "RSI"). Pursuant to the terms of the merger agreement, RSI Bancorp, M.H.C. merged with and into the MHC, with the MHC as the surviving entity; RSI Bancorp, Inc. merged with and into Columbia Financial, with Columbia Financial as the surviving entity; and RSI Bank merged with and into Columbia Bank, with Columbia Bank as the surviving institution. Under the terms of the merger agreement, depositors of RSI Bank became depositors of Columbia Bank and have the same rights and privileges in the MHC as if their accounts had been established at Columbia Bank on the date established at RSI Bank. The Company issued 6,086,314 shares of its common stock to the MHC, representing an amount equal to the discounted fair value of the RSI Entities as determined by an independent appraiser, at the effective time of the merger. Merger-related expenses are recorded in the Consolidated Statements of Income and are expensed as incurred. Direct acquisition and other charges incurred in connection with the acquisition of the RSI Entities totaled $192,099 during both the three and six months ended June 30, 2023. Direct acquisition and other charges incurred in connection with the acquisition of the RSI Entities totaled $1.3 million and $1.5 million, respectively, during the three and six months ended June 30, 2022. The following table sets forth assets acquired, and liabilities assumed in the acquisition of the RSI Entities, at their estimated fair values as of the closing date of the transaction: May 1, 2022 (In thousands) Assets acquired: Cash and cash equivalents $ 140,769 Debt securities available for sale 79,024 Equity securities 1,075 Federal Home Loan Bank Stock 906 Loans receivable 335,501 Accrued interest receivable 910 Office properties and equipment, net 7,296 Bank-owned life insurance 13,033 Deferred tax asset, net 3,633 Core deposit intangibles 10,271 Other assets 2,723 Total assets acquired $ 595,141 Liabilities assumed: Deposits $ 502,732 Borrowings 5,762 Advance payments by borrowers for taxes and insurance 1,341 Accrued expenses and other liabilities 10,568 Total liabilities assumed $ 520,403 Net assets acquired $ 74,738 Fair market value of stock issued to Columbia Bank MHC for purchase 102,741 Goodwill recorded at merger $ 28,003 2. Acquisitions (continued) The assets acquired and liabilities assumed have been accounted for under the acquisition method of accounting. The assets and liabilities were recorded at their fair values as of May 1, 2022, and resulted in the recognition of goodwill of $28.0 million. The determination of the fair value of assets acquired and liabilities assumed 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 subject to change. During the third quarter of 2022, the Company completed all tax returns related to the operation of RSI Bank and its impact on the Company's income taxes, which resulted in a $2.0 million adjustment to deferred income taxes, net, and a corresponding decrease in goodwill. During the fourth quarter of 2022, the Company recorded an adjustment of $490,922 to the original discounted fair value, which resulted in a decrease in additional paid-in-capital, and a corresponding decrease in goodwill. At June 30, 2023 and December 31, 2022, goodwill related to the acquisition of the RSI Entities totaled $25.5 million. Fair Value Measurement of Assets Acquired and Liabilities Assumed Described below are the methods used to determine the fair values of the significant assets acquired and liabilities assumed in the RSI acquisition: Cash and cash equivalents . The estimated fair values of cash and cash equivalents approximate their stated face amounts, as these financial instruments are either due on demand or have short-term maturities. Debt securities available for sale . The estimated fair values of the debt securities were calculated utilizing Level 2 inputs. The majority of the acquired securities were fixed income instruments that are not quoted on an exchange but are traded in active markets. The prices for these instruments are obtained through an independent pricing service when available, or dealer market participants with whom the Company has historically transacted with for both purchases and sales of securities. The prices are derived from market quotations and matrix pricing. The fair value measurements consider observable data that may include dealer quotes, market spreads, cash flows, the U.S. Treasury yield curve, and the bond's terms and conditions, among other things. Management reviewed the data and assumptions used in pricing securities by its third party provider to ensure the highest level of significant inputs are derived from market observable data. Loans receivable . The acquired loan portfolio was segregated into pools for valuation purposes primarily based on loan type, non-accrual status, and credit risk rating. The estimated fair values were computed by discounting the expected cash flows from the respective pools. Cash flows were estimated by using valuation models that incorporated estimates of current key assumptions such as prepayment speeds, default rates, and loss severity rates. The process included: (1) projecting monthly principal and/or interest cash flows based on the contractual terms of the loans, including both maturity and contractual amortization; (2) adjusting projected cash flows for expected losses and prepayments, where appropriate; (3) developing a discount rate based on the relative risk of the cash flows, considering the loan type, liquidity risk, the maturity of the loans, servicing costs, and a required return on capital; and (4) discounting the projected cash flows to a present value, to arrive at the calculated value of the loans. The methods used to estimate the fair values of loans are extremely sensitive to the assumptions and estimates used. While management attempted to use assumptions and estimates that best reflected the acquired loan portfolios and current market conditions, a greater degree of subjectivity is inherent in the values than in those determined in active markets. Office properties and equipment, net . The fair value of land and buildings was estimated using current appraisals. Acquired equipment was not material. Buildings are amortized over their estimated useful lives. Equipment is amortized or depreciated over their estimated useful lives usually ranging from three Goodwill . Goodwill is not amortized for book purposes: however, it is reviewed at least annually for impairment and is not deductible for tax purposes. Core deposit intangibles . Core deposit intangibles ("CDI") are the measure of the value of non-maturity deposits in a business combination. The fair value of the CDI was calculated utilizing the cost savings approach, the expected cost savings attributable to the core deposits funding relative to an alternative source of funding, using a discounted cash flow present value methodology. Key inputs and assumptions utilized in the discounted cash flow present value methodology include core deposit balances and rates paid, the cost of an additional funding source, the aggregate life of deposits and truncation points, non-interest deposit costs, and the immediate deposit outflow assumption. 2. Acquisitions (continued) Deposits . The fair values of deposit liabilities with no stated maturity (i.e., non-interest-bearing and interest-bearing demand deposit accounts, money market and savings and club accounts) are equal to the carrying amounts payable on demand. The fair value of certificates of deposit represents contractual cash flows, discounted to present value using interest rates currently offered on deposits with similar characteristics and remaining maturities. Borrowings . The fair values of borrowings consisting of FHLB advances were estimated by discounting future cash flows using market discount rates for borrowings with similar characteristics, terms and remaining maturities.

Earnings Per Share [Abstract]
Earnings Per Share	Earnings per Share Basic earnings per share ("EPS") is computed by dividing net income available to common shareholders by the weighted average number of common shares outstanding during the period. For purposes of calculating basic EPS, weighted average common shares outstanding excludes treasury stock, unallocated employee stock ownership plan shares that have not been committed for release and deferred compensation obligations required to be settled in shares of Company stock. Diluted EPS is computed using the same method as basic EPS and reflects the potential dilution which could occur if stock options and unvested shares were exercised and converted into common stock. The potentially diluted shares would then be included in the weighted average number of shares outstanding for the period using the treasury stock method. The following is a reconciliation of the numerators and denominators of the basic and diluted earnings per share calculations for the three and six months ended June 30, 2023 and 2022: For the Three Months Ended June 30, For the Six Months Ended June 30, 2023 2022 2023 2022 (In thousands, except per share data) Net income $ 1,664 $ 22,959 $ 20,387 $ 43,363 Shares: Weighted average shares outstanding - basic 102,409,035 106,204,230 103,514,169 104,684,765 Weighted average diluted shares outstanding 108,549 546,327 321,066 561,539 Weighted average shares outstanding - diluted 102,517,584 106,750,557 103,835,235 105,246,304 Earnings per share: Basic $ 0.02 $ 0.22 $ 0.20 $ 0.41 Diluted $ 0.02 $ 0.22 $ 0.20 $ 0.41 During the three and six months ended June 30, 2023 and 2022, the average number of stock options which could potentially dilute basic earnings per share in the future that were not included in the computation of diluted earnings per share because to do so would have been anti-dilutive totaled 527,338 and 438,712, and 237,110 and 73,753, respectively.

Accounting Standards Update and Change in Accounting Principle [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Accounting Pronouncements Adopted In March 2022, the FASB issued ASU 2022-01, Derivatives and Hedging (Topic 815): Fair Value Hedging – Portfolio Layer Method . The purpose of this updated guidance is to further align risk management objectives with hedge accounting results on the application of the last-of-layer method, which was first introduced in ASU 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities. ASU 2022-01 is effective for public business entities for fiscal years beginning after December 15, 2022, with early adoption in the interim period, permitted. For entities who have already adopted ASU 2017-12, immediate adoption is allowed. ASU 2022-01 requires a modified retrospective transition method for basis adjustments in which the entity will recognize the cumulative effect of the change on the opening balance of each affected component of equity in the statement of financial position as of the date of adoption. The Company adopted this ASU on January 1, 2023 on a prospective basis; therefore, there was no impact to 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 . ASU 2022-02 addresses areas identified by the FASB as part of its post-implementation review of the credit losses standard (ASU 2016-13) that introduced the CECL model. The amendments eliminated the accounting guidance for troubled debt restructurings by creditors that have adopted the CECL model and enhanced the disclosure requirements for loan refinancing and restructurings made with borrowers experiencing financial difficulty. In addition, the amendments required a public business entity to disclose current period gross write-offs for financing receivables and net investment in leases by year of origination in the vintage disclosures. For entities that adopted ASU 2016-13, this ASU was effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. The Company adopted this pronouncement effective January 1, 2023. The update was applied on a prospective basis to disclosures and did not have a significant impact on the Company's consolidated financial statements. In June 2016, the FASB issued ASU 2016-13, Financial Instruments- Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments ("CECL") , further amended by ASU 2019-04, Codification Improvements to Topic 326, Financial Instruments-Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments . Topic 326 pertains to the measurement of credit losses on financial instruments. This update requires the measurement of all expected credit losses for financial instruments held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. Financial institutions and other organizations will now use forward-looking information to better determine their credit loss estimates. This update is intended to improve financial reporting by requiring timelier recording of credit losses on loans and other financial instruments held by financial institutions and other organizations. This update was effective for financial statements issued for fiscal years and interim periods beginning after December 15, 2019. The Company elected to defer the adoption of the CECL methodology until December 31, 2020 as permitted by the enacted Coronavirus Aid, Relief and Economic Security Act ("CARES Act"). In late December 2020, the Consolidated Appropriations Act, 2021 was enacted, and extended certain provisions of the CARES Act, which allowed the Company to extend the adoption of CECL until January 1, 2022. The Company elected to extend its adoption of CECL in accordance with this legislation, and adopted the above mentioned ASUs related to Financial Instruments -Credit Losses (Topic 326) using a modified retrospective approach. 5. Summary of Significant Accounting Policies (continued) Accounting Pronouncements Adopted (continued) The Company adopted ASU 2016-13 on January 1, 2022 for all financial assets measured at amortized cost and off-balance- sheet credit exposures. Results are presented under Accounting Standards Codification 326, Financial Instruments - Credit Losses.

All temporarily impaired securities were investment grade as of June 30, 2023 and December 31, 2022. For available for sale securities, the Company assesses whether a loss is from credit or other factors and 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 adverse conditions 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 are compared to the amortized cost basis of the security. If the present value of cash flows is less than the amortized cost, a credit loss would be recorded through an allowance for credit losses, limited by the amount that the fair value is less than the amortized cost basis. The following table presents the activity in the allowance for credit losses on debt securities available for sale for the three and six months ended June 30, 2023 and 2022: For the Three Months Ended June 30, For the Six Months Ended June 30, 2023 2022 2023 2022 (In thousands) Allowance for Credit Losses: Beginning balance $ — $ 1,144 $ — $ — Impact of adopting ASU 2016-13 (CECL) effective January 1, 2022 — — — 490 Provision for credit losses — (1,144) — (490) Ending balance $ — $ — $ — $ — The Company made an accounting policy election to exclude accrued interest receivable from the amortized cost basis of debt securities available for sale.

All temporarily impaired securities were investment grade as of June 30, 2023 and December 31, 2022. For held to maturity securities, management measures expected credit losses on a collective basis by major security type. All of the mortgage-backed securities are issued by U.S. government agencies and are either explicitly or implicitly guaranteed by the U.S. government, are highly rated by major rating agencies and have a long history of no credit losses and, therefore, the expectation of non-payment is zero and the Company is not required to estimate an allowance for credit losses on these securities under the CECL standard. All these securities reflect a credit quality rating of AAA by Moody's Investors Service. The Company made an accounting policy election to exclude accrued interest receivable from the amortized cost basis of debt securities held to maturity. Accrued interest receivable on debt securities held to maturity is reported as a component of accrued interest receivable on the Consolidated Statement of Financial Condition, which totaled $987,000 and $1.0 million at June 30, 2023 and December 31, 2022, respectively, and is excluded from the estimate of credit losses. The Company has an equity securities portfolio which consists of stock in other financial institutions, a payment technology company, a community bank correspondent services company, preferred stock in U.S. Government agencies, and a Community Reinvestment Act qualifying bond fund which are reported at fair value on the Company's Consolidated Statements of Financial Condition. The fair value of the equities portfolio at June 30, 2023 and December 31, 2022 was $3.7 million and $3.4 million, respectively. The Company recorded a net increase (decrease) in the fair value of equity securities of $162,000 and $330,000, and $(147,000) and $(68,000), respectively, during the three and six months ended June 30, 2023 and 2022, respectively, as a component of non-interest income.

Loans Receivable and Allowance for Credit Losses (continued) At June 30, 2023 and December 31, 2022, the carrying value of loans serviced by the Company for investors was $552.0 million and $497.1 million, respectively. These loans are not included in the Consolidated Statements of Financial Condition. The following tables summarize the aging of loans receivable by portfolio segment, including non-accrual loans and excluding PCD loans at June 30, 2023 and December 31, 2022: June 30, 2023 30-59 Days 60-89 Days 90 Days or More Total Past Due Non-accrual Current Total (In thousands) Real estate loans: One-to-four family $ 7,826 $ 3,154 $ 2,493 $ 13,473 $ 4,077 $ 2,775,796 $ 2,789,269 Multifamily 2,101 — — 2,101 — 1,374,898 1,376,999 Commercial real estate 203 1,942 3,745 5,890 3,744 2,381,006 2,386,896 Construction — — — — — 378,988 378,988 Commercial business loans — 228 2,915 3,143 3,067 502,381 505,524 Consumer loans: Home equity loans and advances 229 59 148 436 203 268,874 269,310 Other consumer loans — 17 — 17 — 2,535 2,552 Total loans $ 10,359 $ 5,400 $ 9,301 $ 25,060 $ 11,091 $ 7,684,478 $ 7,709,538 December 31, 2022 30-59 Days 60-89 Days 90 Days or More Total Past Due Non-accrual Current Total (In thousands) Real estate loans: One-to-four family $ 4,063 $ 1,149 $ 1,808 $ 7,020 $ 2,730 $ 2,853,164 $ 2,860,184 Multifamily — — — — — 1,239,207 1,239,207 Commercial real estate — 853 2,892 3,745 2,892 2,409,649 2,413,394 Construction 5,218 — — 5,218 — 331,335 336,553 Commercial business loans 220 — 474 694 801 496,775 497,469 Consumer loans: Home equity loans and advances 465 33 286 784 286 273,518 274,302 Other consumer loans 3 1 12 16 12 3,409 3,425 Total loans $ 9,969 $ 2,036 $ 5,472 $ 17,477 $ 6,721 $ 7,607,057 $ 7,624,534 The Company considers a loan to be delinquent when we have not received a payment within 30 days of its contractual due date. Generally, a loan is designated as a non-accrual loan when the payment of interest is 90 days or more in arrears of its contractual due date. Non-accruing loans are returned to accrual status after there has been a sustained period of repayment performance (generally six consecutive months of payments) and both principal and interest are deemed collectible. The Company identifies loans that may need to be charged-off as a loss, by reviewing all delinquent loans, classified loans and other loans that management may have concerns about collectability. At June 30, 2023 and December 31, 2022, non-accrual loans totaled $11.1 million and $6.7 million, respectively. Included in non-accrual loans at June 30, 2023 and December 31, 2022, are 12 and 7 loans totaling $1.8 million and $1.2 million, respectively, which are less than 90 days in arrears. 9. Loans Receivable and Allowance for Credit Losses (continued) At June 30, 2023 there were no loans past due 90 days or more still accruing interest. At June 30, 2023 and December 31, 2022, there were no loans past due 90 days or more still accruing interest other than COVID-19 related loan forbearances and deferrals. In accordance with the CARES Act, these loans were not included in the aging of loans receivable by portfolio segment in the table above, and the Company continued to accrue interest income during the forbearance or deferral period. Purchased credit impaired loans ("PCI") were loans acquired at a discount primarily due to deteriorated credit quality. These loans were initially recorded at fair value at acquisition, based upon the present value of expected future cash flows, with no related allowance for credit losses. In connection with the adoption of CECL on January 1, 2022, all loans considered PCI loans prior to that date were converted to purchase credit-deteriorated ("PCD") loans. Loans acquired in a business combination after January 1, 2022 are recorded in accordance with ASC Topic 326, which requires loans as of the acquisition date, that have experienced a more than insignificant deterioration in credit quality since origination to be classified as PCD loans. At June 30, 2023 and December 31, 2022, PCD loans acquired in the Stewardship Financial Corporation ("Stewardship") acquisition totaled $1.8 million and $2.0 million, respectively, PCD loans acquired in the Roselle Bank acquisition totaled $0 and $184,000, respectively, PCD loans acquired in the Freehold Bank acquisition totaled $3.6 million and $3.7 million, respectively, and PCD loans acquired in the RSI Bank acquisition totaled $10.7 million and $11.3 million, respectively. We may obtain physical possession of real estate collateralizing a residential mortgage loan via foreclosure or through an in-substance repossession. At June 30, 2023 and December 31, 2022, the Company had no real estate owned. At June 30, 2023 we had one one-to-four family loan with a carrying value of $641,000 and two home equity loans with a total carrying value of $148,000, collateralized by residential real estate which were in the process of foreclosure. At December 31, 2022, we had two home equity loans with a total carrying value of $81,000, collateralized by residential real estate which were in the process of foreclosure. On January 1, 2022, the Company adopted CECL (ASC Topic 326), which replaced the historical incurred loss methodology with an expected loss methodology. The loan portfolio segmentation was expanded to seven portfolio segments taking into consideration common loan attributes and risk characteristics, as well as historical reporting metrics and data availability. The Company made an accounting policy election to exclude accrued interest receivable from the amortized cost basis of loans receivable. Accrued interest receivable on loans receivable is reported as a component of accrued interest receivable in the Consolidated Statement of Financial Condition, which totaled $30.8 million and $29.4 million at June 30, 2023 and December 31, 2022, respectively, and is excluded from the estimate of credit losses. The allowance for credit losses on loans reflects management’s evaluation of the current expected credit losses in the loan portfolio. The Company maintains the allowance for credit losses through provisions for credit losses that are charged to income. Charge-offs against the allowance for credit losses are taken on loans where management determines that the collection of loan principal and interest is unlikely. Recoveries made on loans that have been charged-off are credited to the allowance for credit losses. Management estimates the allowance balance using relevant available information, from internal and external sources, related to past events, current conditions, and a reasonable and supportable forecast. Historical credit loss experience for both the Company and peers provides the basis for the estimation of expected credit losses, where observed credit losses are converted to probability of default rate through the use of segment-specific loss given default risk factors that convert default rates to loss severity based on industry-level, observed relationships between the two variables for each segment, primarily due to the nature of the underlying collateral. These risk factors were assessed for reasonableness against the Company’s own loss experience and adjusted in certain cases when the relationship between the Company’s historical default and loss severity deviate from that of the wider industry. The historical probability of default ("PD") curves, together with corresponding economic conditions, establish a quantitative relationship between economic conditions and loan performance through an economic cycle. Using the historical relationship between economic conditions and loan performance, management’s expectation of future loan performance is incorporated using an externally developed economic forecast. This forecast is applied over a period that management has determined to be reasonable and supportable. Beyond the period over which management can develop or source a reasonable and supportable forecast, the model will revert to long-term average economic conditions using a straight-line, time-based methodology. The Company's current forecast period is six quarters, with a four quarter reversion period to historical average macroeconomic factors. 9. Loans Receivable and Allowance for Credit Losses (continued) The allowance for credit losses is measured on a collective (pool) basis, with both a quantitative and qualitative analysis that is applied on a quarterly basis, when similar risk characteristics exist. The respective quantitative allowance for each segment is measured using an economic forecast, discounted cash flow modeling methodology in which distinct, segment-specific multi-variate regression models are applied to an external economic forecast. Under the discounted cash flows methodology, expected credit losses are estimated over the effective life of the loans by measuring the difference between the net present value of modeled cash flows and amortized cost basis. Contractual cash flows over the contractual life of the loans are the basis for modeled cash flows, adjusted for modeled defaults and expected prepayments and discounted at the loan-level effective interest rate. The contractual term excludes expected extensions, renewals, and modifications. After quantitative considerations, management applies additional qualitative adjustments so that the allowance for credit loss is reflective of the estimate of lifetime losses that exist in the loan portfolio at the balance sheet date. Portfolio segment is defined as the level at which an entity develops and documents a systematic methodology to determine its allowance for credit losses. Management developed segments for estimating loss based on type of borrower and collateral, which is generally based upon federal call report segmentation. The segments have been combined or sub-segmented as needed to ensure loans of similar risk profiles are appropriately pooled. The allowance for credit losses on loans individually analyzed for impairment is based upon loans that have been identified through the Company’s loan monitoring process. This process includes the review of delinquent, restructured, and charged-off loans. Management believes the primary risks inherent in the portfolio are a general decline in the economy, a decline in real estate market values, rising unemployment, and increases in interest rates in the absence of economic improvement. Any one or a combination of these events may adversely affect a borrower's ability to repay its loan, resulting in increased delinquencies and loan losses. Accordingly, the Company has recorded loan losses at a level which is estimated to represent the current risk in its loan portfolio. Management considers it important to maintain the ratio of the allowance for credit losses to total loans at an acceptable level considering the current composition of the loan portfolio. 9.

This guidance was applied on a prospective basis. Modifications made to borrowers experiencing financial difficulty may include principal or interest forgiveness, forbearance, interest rate reductions, term extensions, or a combination of these events intended to minimize economic loss and to avoid foreclosure or repossession of collateral. For the three and six months ended June 30, 2023, the Company modified one construction loan with an outstanding balance of $2.3 million and one commercial business loan with an outstanding balance of $240,000, to borrowers experiencing financial difficulty. All loans to borrowers experiencing financial difficulty that have been modified during the three and six months ended June 30, 2023 were current as to their contractual payments at June 30, 2023. For the three and six months ended June 30, 2022 there were no modifications. 9.

The categorization of loans into risk categories is based upon relevant information about the borrower's ability to service their debt. The Company utilizes an eight-point risk rating system to summarize its loan portfolio into categories with similar risk characteristics. Loans deemed to be “acceptable quality” are rated 1 through 4 (Pass), with a rating of 1 established for loans with minimal risk. Loans that are deemed to be of “questionable quality” are rated 5 (Special Mention) or 6 (Substandard). Loans with adverse classifications are rated 7 (Doubtful) or 8 (Loss). The risk ratings are also confirmed through periodic loan review examinations which are currently performed by both an independent third-party and the Company's credit risk review department. The Company requires an annual review be performed above certain dollar thresholds, depending on loan type, to help determine the appropriate risk ratings. Results from examinations are presented to the Audit Committee of the Board of Directors. 9.

Loans Receivable and Allowance for Credit Losses (continued) The Company is required to include unfunded commitments that are expected to be funded in the future within the allowance calculation, other than those that are unconditionally cancellable. To arrive at that reserve, the reserve percentage for each applicable segment is applied to the unused portion of the expected commitment balance and is multiplied by the expected funding rate. To determine the expected funding rate, the Company uses a historical utilization rate for each segment. The allowance for credit losses for off-balance-sheet exposures is reported in other liabilities in the Consolidated Statements of Financial Condition. The liability represents an estimate of expected credit losses arising from off-balance-sheet exposures such as unfunded commitments. At June 30, 2023 and December 31, 2022, the balance of the allowance for credit losses on unfunded commitments, included in other liabilities, totaled $6.3 million and $7.0 million, respectively. The Company recorded a (reversal of) provision for credit losses on unfunded commitments, included in other non-interest expense in the Consolidated Statements of Income, of $(111,900) and $(640,000) and $(488,200) and $160,000 during the three and six months ended June 30, 2023 and 2022, respectively. The following table presents the activity in the allowance for credit losses on off-balance-sheet exposures for the three and six months ended June 30, 2023 and 2022: Three Months Ended June 30, Six Months Ended June 30, 2023 2022 2023 2022 (In thousands) Allowance for Credit Losses: Beginning balance $ 6,442 $ 8,846 $ 6,970 $ 524 Impact of adopting ASU 2016-13 ("CECL") effective January 1, 2022 — — — 7,674 (Reversal of) provision for credit losses (112) (488) (640) 160 Balance at end of period $ 6,330 $ 8,358 $ 6,330 $ 8,358

Leases

Leases	6 Months Ended

Leases [Abstract]
Leases	Leases The Company's leases real estate property for branches and office space. At June 30, 2023 and December 31, 2022, all of the Company's leases are classified as operating leases. The Company determines if an arrangement is a lease at inception. Topic 842 requires lessees to recognize a right-of-use asset and a lease liability, measured at the present value of the future minimum lease payments, at the lease commencement date. The calculated amount of the right-of-use asset and lease liabilities are impacted by the length of the lease term and the discount rate used to calculate the present value of minimum lease payments. At June 30, 2023 and December 31, 2022, the weighted average remaining lease term for operating leases was 6.1 years and 6.5 years, respectively, and the weighted average discount rate used in the measurement of operating lease liabilities was 2.49% and 2.35%, respectively. The Company elected to account for the lease and non-lease components separately since such amounts are readily determinable under the Company's lease contracts. Operating lease expense is recognized on a straight-line basis over the lease term, while variable lease payments are recognized as incurred. Variable lease payments include common area maintenance charges, real estate taxes, repairs and maintenance costs and utilities. Operating and variable lease expenses are recorded in occupancy expense in the Consolidated Statements of Income. During the three months ended June 30, 2023 and 2022, operating and variable lease expenses totaled approximately $680,000 and $607,000, respectively. During the six months ended June 30, 2023 and 2022, operating and variable lease expenses totaled approximately $1.3 million for both periods. There were no sale and leaseback transactions, leveraged leases or lease transactions with related parties during the three and six months ended June 30, 2023 and 2022. At June 30, 2023, the Company had not entered into any leases which had not yet commenced. 10. Leases (continued) The following table summarizes lease payment obligations for each of the next five years and thereafter as follows: Lease Payment Obligations at June 30, 2023 December 31, 2022 (In thousands) One year or less $ 2,301 $ 4,290 After one year to two years 4,030 3,745 After two years to three years 3,265 3,075 After three years to four years 2,883 2,773 After four years to five years 2,000 2,000 Thereafter 4,345 4,345 Total undiscounted cash flows 18,824 20,228 Discount on cash flows (1,451) (1,613) Total lease liability $ 17,373 $ 18,615

Restricted shares granted under the 2019 Plan generally vest in equal installments, over performance or service periods ranging from 1 year to 5 years, beginning 1 year from the date of grant. A portion of restricted shares awarded are performance awards, which vest upon the satisfactory attainment of certain corporate financial targets. Management recognizes compensation expense for the fair value of restricted shares on a straight-line basis over the requisite performance or service period. During the three months ended June 30, 2023 and 2022, approximately $1.1 million and $1.4 million in expense was recognized in regard to these awards. The expected future compensation expense related to the 618,750 non-vested restricted shares outstanding at June 30, 2023 is approximately $7.4 million over a weighted average period of 1.8 years. During the six months ended June 30, 2023 and 2022, approximately $2.0 million and $2.5 million in expense was recognized in regard to these awards. 12. Stock Based Compensation (continued) The following is a summary of the Company's restricted stock activity during the three and six months ended June 30, 2023 and 2022: Number of Restricted Shares Weighted Average Grant Date Fair Value Non-vested at January 1, 2023 430,954 $ 17.31 Vested (26,424) 21.16 Forfeited (1,929) 21.12 Non-vested at March 31, 2023 402,601 $ 17.10 Grants 226,574 16.19 Forfeited (10,425) 18.51 Non-vested at June 30, 2023 618,750 $ 16.74 Number of Restricted Shares Weighted Average Grant Date Fair Value Non-vested at January 1, 2022 1,054,335 $ 15.78 Grants 51,746 21.79 Vested (27,775) 17.86 Forfeited (31,570) 16.91 Non-vested at March 31, 2022 1,046,736 $ 15.98 Forfeited (5,182) 18.34 Non-vested at June 30, 2022 1,041,554 $ 15.97 On March 21, 2022, options to purchase 130,951 shares of Company common stock were awarded with a grant date fair value of $6.51 per option. These stock options granted under the 2019 Plan on such date, vest in equal installments over the service period of three years beginning from the date of grant. These stock options were granted at an exercise price of $21.79, which represents the fair value of the Company's common stock price on the grant date based on the closing market price, and have an expiration period of approximately 10 years. The fair value of stock options granted was estimated utilizing the Black-Scholes option pricing model using the following assumptions: expected life of six years risk-free rate of return of 2.34%, volatility of 25.31%, and a dividend yield of 0.00%. On October 31, 2022, options to purchase 173,766 shares of Company common stock were awarded with a grant date fair value of $7.22 per option. Stock options granted under the 2019 Plan vest in equal installments over the service period of three years beginning one year from the date of grant. These stock options were granted at an exercise price of $20.54, which represents the fair value of the Company's common stock price on the grant date based on the closing market price and have an expiration period of 10 years. The fair value of stock options granted was estimated utilizing the Black-Scholes option pricing model using the following assumptions: expected life of 6 years, risk-free rate of return of 4.19%, volatility of 26.25%, and a dividend yield of 0.00%. On December 19, 2022, options to purchase 58,912 shares of Company common stock were awarded with a grant date fair value of $6.79 per option. Stock options granted under the 2019 Plan generally vest in equal installments over the service period of one year beginning one year from the date of grant. These stock options were granted at an exercise price of $21.07, which represents the fair value of the Company's common stock price on the grant date based on the closing market price and have an expiration period of approximately 10 years. The fair value of stock options granted was estimated utilizing the Black-Scholes option pricing model using the following assumptions: expected life of 5.5 years, risk-free rate of return of 3.71%, volatility of 26.11%, and a dividend yield of 0.00%. 12. Stock Based Compensation (continued) On May 1, 2023, options to purchase 286,016 shares of Company common stock were awarded with a grant date fair value of $5.48 per option. Stock options granted under the 2019 Plan generally vest in equal installments over the service period of one year beginning one year from the date of grant. These stock options were granted at an exercise price of $15.94, which represents the fair value of the Company's common stock price on the grant date based on the closing market price and have an expiration period of approximately 10 years. The fair value of stock options granted was estimated utilizing the Black-Scholes option pricing model using the following assumptions: expected life of 6 years, risk-free rate of return of 3.60%, volatility of 27.07%, and a dividend yield of 0.00%. The expected life of the options represents the period of time that stock options are expected to be outstanding and is estimated using the simplified approach, which assumes that all outstanding options will be exercised at the midpoint of the vesting date and full contractual term. The risk-free rate of return is based on the rates on the grant date of a U.S. Treasury Note with a term equal to the expected option life. Since the Company recently converted to a public company and does not have sufficient historical price data, the expected volatility is based on the historical daily stock prices of Company stock plus a peer group of similar entities based on factors such as industry, stage of life cycle, size and financial leverage. The Company has not paid any cash dividends on its common stock. Management recognizes expense for the fair value of these awards on a straight-line basis over the requisite service period. During the three months ended June 30, 2023 and 2022, approximately $954,000 and $811,000 in expense was recognized in regard to these awards. The expected future compensation expense related to the 1,785,804 non-vested options outstanding at June 30, 2023 is $5.8 million over a weighted average period of 1.7 years. During the six months ended June 30, 2023 and 2022, approximately $1.9 million and $1.6 million in expense was recognized in regard to these awards.

Retirement Benefits [Abstract]
Components of Periodic Benefit Cost	Components of Net Periodic Benefit Cost Pension Plan, Retirement Income Maintenance Plan (the "RIM Plan") Post-retirement Plan, and Split-Dollar Life Insurance Plans The Company maintains a single employer, tax-qualified defined benefit pension plan (the "Pension Plan") which covers full-time employees that satisfy the Pension Plan's eligibility requirements. The benefits are based on years of service and the employee's average compensation for the highest five The Company also maintains a Retirement Income Maintenance Plan (the "RIM Plan") which is a non-qualified defined benefit plan which provides benefits to all employees of the Company if their benefits under the Pension Plan are limited by Internal Revenue Code Sections 415 and 401(a)(17). In addition, the Company provides certain health care and life insurance benefits to eligible retired employees under a Post-retirement Plan. The Company accrues the cost of retiree health care and other benefits during the employee's period of active service. Effective January 1, 2019, the Post-retirement Plan has been closed to new hires. The Company also provides life insurance benefits to eligible employees under an endorsement split-dollar life insurance program. The Company recognizes a liability for future benefits applicable to endorsement split-dollar life insurance arrangements that provide death benefits post-retirement. Through its mergers, the Company recognized additional liability for future benefits applicable to endorsement split-dollar life insurance arrangements that provide death benefits post-retirement under those respective Bank's program. 13. Components of Net Periodic Benefit Cost (continued) Net periodic (income) benefit cost for the Pension Plan, RIM Plan, Post-retirement Plan and Split-Dollar Life Insurance plan benefits for the three and six months ended June 30, 2023 and 2022, includes the following components: For the Three Months Ended June 30, Pension Plan RIM Plan Post-retirement Plan Split-Dollar Life Insurance 2023 2022 2023 2022 2023 2022 2023 2022 Affected Line Item in the Consolidated Statements of Income (In thousands) Service cost $ 1,199 $ 1,966 $ 69 $ 93 $ 54 $ 87 $ 69 $ 128 Compensation and employee benefits Interest cost 2,790 2,031 158 97 242 150 204 153 Other non-interest expense Expected return on plan assets (7,480) (7,559) — — — — — — Other non-interest expense Amortization: Prior service cost — — 14 — — — 14 14 Other non-interest expense Net loss — — — 111 — 78 — 151 Other non-interest expense Net periodic (income) benefit cost $ (3,491) $ (3,562) $ 241 $ 301 $ 296 $ 315 $ 287 $ 446 For the Six Months Ended June 30, Pension Plan RIM Plan Post-retirement Plan Split-Dollar Life Insurance 2023 2022 2023 2022 2023 2022 2023 2022 Affected Line Item in the Consolidated Statements of Income (In thousands) Service cost $ 2,398 $ 3,932 $ 138 $ 186 $ 108 $ 174 $ 139 $ 253 Compensation and employee benefits Interest cost 5,581 4,062 316 194 485 300 409 295 Other non-interest expense Expected return on plan assets (14,960) (15,118) — — — — — — Other non-interest expense Amortization: Prior service cost — — 28 — — — 28 28 Other non-interest expense Net loss — — — 222 — 156 — 302 Other non-interest expense Net periodic (income) benefit cost $ (6,981) $ (7,124) $ 482 $ 602 $ 593 $ 630 $ 576 $ 878 13.

Fair Value Measurements

Fair Value Measurements	6 Months Ended

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements The Company utilizes fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures. The determination of fair values of financial instruments often requires the use of estimates. Where quoted market values in an active market are not readily available, the Company utilizes various valuation techniques to estimate fair value. 14. Fair Value Measurements (continued) Fair value is the exchange price that would be received for an asset or paid to transfer a liability (exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. There are three levels of inputs that may be used to measure fair values: Level 1: Unadjusted quoted prices for identical assets or liabilities in active markets that the Company has the ability to access on the measurement date. Level 2: Inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. These might include quoted prices for similar instruments in markets that are active or not active, or inputs that are observable or can be corroborated by observable market data for substantially the full term of the asset or liability. Level 3: Prices or valuation techniques that require unobservable inputs that are both significant to the fair value measurement and unobservable (i.e., supported by minimal or no market activity). Valuation techniques include the use of option pricing models, discounted cash flow models and similar techniques. A financial instrument’s level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement. Assets and Liabilities Measured at Fair Value on a Recurring Basis The methods described below were used to measure fair value of financial instruments as reflected in the tables below on a recurring basis at June 30, 2023 and December 31, 2022. Debt Securities Available for Sale, at Fair Value For debt securities available for sale, fair value was estimated using a market approach. The majority of these securities are fixed income instruments that are not quoted on an exchange but are traded in active markets. Prices for these instruments are obtained through third-party data service providers or dealer market participants with which the Company has historically transacted both purchases and sales of securities. Prices obtained from these sources include market quotations, matrix pricing and discounted cash flow pricing. Matrix pricing, a Level 2 input, is a mathematical technique used principally to value certain securities to a benchmark or to comparable securities. The Company evaluates the quality of Level 2 matrix pricing through comparison to similar assets with greater liquidity and evaluation of projected cash flows. Discounted cash flows, a Level 3 input, is estimated by discounting the expected future cash flows using the current rates for securities with similar credit ratings and similar remaining maturities. As the Company is responsible for the determination of fair value, it performs quarterly analysis on the prices received from the pricing service to determine whether the prices are reasonable estimates of fair value. Specifically, the Company compares the prices received from the pricing service to a secondary pricing source. Additionally, the Company compares changes in the reported market values and returns to relevant market indices to assess the reasonableness of the reported prices. The Company’s internal price verification procedures and review of fair value methodology documentation provided by independent pricing services has not historically resulted in an adjustment in the prices obtained from the pricing service. The Company may hold debt instruments issued by the U.S. government and U.S. government-sponsored agencies that are traded in active markets with readily accessible quoted market prices that are considered Level 1 inputs. The Company classifies the estimated fair value of its loan portfolio as Level 3. Equity Securities, at Fair Value The Company holds equity securities that are traded in active markets with readily accessible quoted market prices that are considered Level 1 inputs. A trust preferred security that is not traded in an active market and Federal Home Loan Mortgage Corporation ("FHLMC") and Federal National Mortgage Association ("FNMA") preferred stock are considered Level 2 instruments. In addition, Level 2 instruments include Atlantic Community Bankers Bank ("ACCB") stock, which is based on redemption at par value and can only be sold to the issuing ACBB or another institution that holds ACBB stock. 14. Fair Value Measurements (continued) Derivatives The Company records all derivatives included in other assets and liabilities on the Consolidated Statements of Financial Condition at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, whether the Company has elected to designate a derivative in a hedging relationship and apply hedge accounting, and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. See note 16 for disclosures related to the accounting treatment for derivatives. The fair value of the Company's derivatives is determined using discounted cash flow analysis using observable market-based inputs, which are considered Level 2 inputs. The following tables present the assets and liabilities reported on the Consolidated Statements of Financial Condition at their fair values at June 30, 2023 and December 31, 2022, by level within the fair value hierarchy: June 30, 2023 Fair Value Measurements Fair Value Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) (In thousands) Debt securities available for sale: U.S. government and agency obligations $ 20,926 $ 13,250 $ 7,676 $ — Mortgage-backed securities and collateralized mortgage obligations 896,819 — 896,819 — Municipal obligations 3,586 — 886 2,700 Corporate debt securities 76,128 — 67,747 8,381 Total debt securities available for sale 997,459 13,250 973,128 11,081 Equity securities 3,714 3,393 321 — Derivative assets 27,074 — 27,074 — $ 1,028,247 $ 16,643 $ 1,000,523 $ 11,081 Derivative liabilities $ 18,710 $ — $ 18,710 $ — 14.

Fair Value Measurements (continued) The fair value of investments placed in Level 3 is estimated by discounting the expected future cash flows using reasonably available current rates for comparable new issue securities with similar structure, including original maturity, call date, and assumptions about risk. Discounted cash flow estimated valuations are subsequently validated against comparable structures as an approximation of value. Expected cash flows were projected based on contractual cash flows. At both June 30, 2023 and December 31, 2022, two private placement corporate debt securities classified as available for sale and three private placement municipal obligations classified as available for sale were included in Level 3 assets. There were no transfers to Level 3 assets during the three and six months ended June 30, 2023. Private placement debt security cash flows were discounted to a market yield of 11.00% (weighted average is 11.00%), and the cash flows for private placement municipal obligations were discounted to a market yield ranging from 3.62% to 4.45% (weighted average is 3.94%). The period end valuations were support by an analysis prepared by an independent third party market participant and approved by management. Assets Measured at Fair Value on a Non-Recurring Basis The valuation techniques described below were used to estimate fair value of financial instruments measured on a non-recurring basis at June 30, 2023 and December 31, 2022. Individually Analyzed Collateral Dependent Loans/Impaired Loans The fair value of collateral dependent loans that are individually analyzed or were previously deemed impaired is measured based on the present value of expected future cash flows discounted at the loan's effective interest rate or, as a practical expedient, at the loan's observable market price or the fair value of the collateral if the loan is collateral dependent. For individually analyzed loans measured for impairment based on the fair value of the underlying collateral, fair value was estimated using a market approach. The Company measures the fair value of collateral underlying impaired loans primarily through obtaining independent appraisals that rely upon quoted market prices for similar assets in active markets. These appraisals include adjustments, on an individual case-by-case basis, to comparable assets based on the appraisers’ market knowledge and experience, as well as adjustments for estimated costs to sell between 6% and 8%. For non-collateral dependent loans, management estimates fair value using discounted cash flows based on inputs that are largely observable. The Company classifies these loans as Level 3 within the fair value hierarchy. Mortgage Servicing Rights, Net ("MSR's") Mortgage servicing rights are carried at the lower of cost or estimated fair value. The estimated fair value of MSRs is obtained through an analysis of future cash flows, incorporating assumptions that market participants would use in determining fair value including market discount rates, prepayments speeds, servicing income, servicing costs, default rates and other market driven data, including the market's perception of future interest rate movements. The prepayment speed and the discount rate are considered two of the most significant inputs in the model. A significant degree of judgment is involved in valuing the mortgage servicing rights using Level 3 inputs. The use of different assumptions could have a significant effect on this fair value estimate. 14. Fair Value Measurements (continued) The following tables present the assets and liabilities reported on the Consolidated Statements of Financial Condition at their fair values on a non-recurring basis at June 30, 2023 and December 31, 2022, by level within the fair value hierarchy: June 30, 2023 Fair Value Measurements Fair Value Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) (In thousands) Impaired loans - Commercial real estate $ 1,542 $ — $ — $ 1,542 Impaired loans - Commercial business 1,064 — — 1,064 Mortgage servicing rights 2,829 — — 2,829 $ 5,435 $ — $ — $ 5,435 December 31, 2022 Fair Value Measurements Fair Value Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) (In thousands) Mortgage servicing rights $ 2,107 $ — $ — $ 2,107 $ 2,107 $ — $ — $ 2,107 The following table presents information for Level 3 assets measured at fair value on a non-recurring basis at June 30, 2023 and December 31, 2022: June 30, 2023 Fair Value Valuation Methodology Unobservable Inputs Range of Inputs Weighted Average Rate (Dollars in thousands) Impaired loans - Commercial real estate $ 1,542 Other Contracted sale price of collateral — — Impaired loans - Commercial business 1,064 Other Contracted sale price of collateral /adjustments to reflect current conditions — — Mortgage servicing rights 2,829 Discounted cash flow Prepayment speeds and discount rates (1) 4.6% - 24.1% 8.2 % 14.

(2) Value of SBA servicing rights based on a discount rate of 14.50%. Other Fair Value Disclosures The Company is required to disclose estimated fair value of financial instruments, both assets and liabilities on and off the balance sheet, for which it is practicable to estimate fair value. A description of the valuation methodologies used for those assets and liabilities not recorded at fair value on a recurring or non-recurring basis are set forth below. Cash and Cash Equivalents For cash and due from banks, federal funds sold and short-term investments, the carrying amount approximates fair value due to their nature and short-term maturities. Debt Securities Held to Maturity For debt securities held to maturity, fair value was estimated using a market approach. The majority of the Company’s securities are fixed income instruments that are not quoted on an exchange, but are traded in active markets. Prices for these instruments are obtained through third-party data service providers or dealer market participants with which the Company has historically transacted both purchases and sales of securities. Prices obtained from these sources include market quotations and matrix pricing. Matrix pricing, a Level 2 input, is a mathematical technique used principally to value certain securities to a benchmark or to comparable securities. The Company evaluates the quality of Level 2 matrix pricing through comparison to similar assets with greater liquidity and evaluation of projected cash flows. As the Company is responsible for the determination of fair value, it performs quarterly analysis on the prices received from the pricing service to determine whether the prices are reasonable estimates of fair value. Specifically, the Company compares the prices received from the pricing service to a secondary pricing source. Additionally, the Company compares changes in the reported market values and returns to relevant market indices to assess the reasonableness of the reported prices. The Company’s internal price verification procedures and review of fair value methodology documentation provided by independent pricing services has not historically resulted in an adjustment in the prices obtained from the pricing service. The Company also holds debt instruments issued by the U.S. government and U.S. government-sponsored agencies that are traded in active markets with readily accessible quoted market prices that are considered Level 1 inputs within the fair value hierarchy. Federal Home Loan Bank Stock ("FHLB") The fair value of FHLB stock is based on redemption at par value and can only be sold to the issuing FHLB, to other FHLBs, or to other member banks. As such, the Company's FHLB stock is recorded at cost, or par value, and is evaluated for impairment each reporting period by considering the ultimate recoverability of the investment rather than temporary declines in value. The Company classifies the estimated fair value as Level 2 within the fair value hierarchy. 14. Fair Value Measurements (continued) Loans Receivable Fair values are estimated for portfolios of loans with similar financial characteristics. Loans are segregated by type such as commercial mortgage, residential mortgage, commercial, construction, consumer, and other. Each loan category is further segmented into fixed and adjustable rate interest terms and into performing and non-performing categories. The fair value of performing loans was estimated using a combination of techniques, including a discounted cash flow model that utilizes a discount rate that reflects the Company's current pricing for loans with similar characteristics and remaining maturity, adjusted by an amount for estimated credit losses inherent in the portfolio at the balance sheet date. The rates take into account the expected yield curve, as well as an adjustment for prepayment risk, when applicable. The Company classifies the estimated fair value of its loan portfolio as Level 3. The fair value for significant non-performing loans was based on recent external appraisals of collateral securing such loans, adjusted for the timing of anticipated cash flows. The Company classifies the estimated fair value of its non-performing loan portfolio as Level 3. Deposits The fair value of deposits with no stated maturity, such as demand, money market, and savings and club deposits are payable on demand at each reporting date and classified as Level 2. The estimated fair value of certificates of deposit was based on the discounted value of contractual cash flows. The discount rate was estimated using the Company’s current rates offered for deposits with similar remaining maturities. The Company classifies the estimated fair value of its certificates of deposit portfolio as Level 2. Borrowings The fair value of borrowings was estimated by discounting future cash flows using rates available for debt with similar terms and maturities and is classified by the Company as Level 2 within the fair value hierarchy. Commitments to Extend Credit and Letters of Credit The fair value of commitments to extend credit and letters of credit was estimated using the fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreements and the present creditworthiness of the counter-parties. For fixed rate loan commitments, fair value also considers the difference between current levels of interest rates and the committed rates. The fair value estimates of commitments to extend credit and letters of credit are deemed immaterial. 14.

Fair Value Measurements (continued) 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 limited markets exist 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 factors. 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 on and off-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. Other significant assets and liabilities that are not considered financial assets or liabilities include goodwill and intangible assets, deferred tax assets and liabilities, office properties and equipment, and bank-owned life insurance.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives and Hedging Activities	Derivatives and Hedging Activities The Company uses derivative financial instruments as components of its market risk management, principally to manage interest rate risk. Certain derivatives are entered into in connection with transactions with commercial customers. Derivatives are not used for speculative purposes. All derivatives are recognized as either assets or liabilities in the Consolidated Statements of Financial Condition, reported at fair value and presented on a gross basis. Until a derivative is settled, a favorable change in fair value results in an unrealized gain that is recognized as an asset, while an unfavorable change in fair value results in an unrealized loss that is recognized as a liability. The Company generally applies hedge accounting to its derivatives used for market risk management purposes. Hedge accounting is permitted only if specific criteria are met, including a requirement that a highly effective relationship exists between the derivative instrument and the hedged item, both at inception of the hedge and on an ongoing basis. Changes in the fair value of effective fair value hedges are recognized in current earnings (with the change in fair value of the hedged asset or liability also recognized in earnings). Changes in the fair value of effective cash flow hedges are recognized in other comprehensive income (loss) until earnings are affected by the variability in cash flows of the designated hedged item. Ineffective portions of hedge results are recognized in current earnings. Changes in the fair value of derivatives for which hedge accounting is not applied are recognized in current earnings. The Company formally documents at inception all relationships between the derivative instruments and the hedged items, as well as its risk management objectives and strategies for undertaking the hedge transactions. This process includes linking all derivatives that are designated as hedges to specific assets and liabilities, or to specific firm commitments. The Company also formally assesses, both at inception of the hedge and on an ongoing basis, whether the derivatives that are used in hedging transactions are highly effective in offsetting changes in the fair values or cash flows of the hedged items. If it is determined that a derivative is not highly effective or has ceased to be a highly effective hedge, the Company would discontinue hedge accounting prospectively. Gains or losses resulting from the termination of a derivative accounted for as a cash flow hedge remain in other comprehensive income (loss) and is (accreted) amortized to earnings over the remaining period of the former hedging relationship. Certain derivative financial instruments are offered to certain commercial banking customers to manage their risk of exposure and risk management strategies. These derivative instruments consist primarily of currency forward contracts and interest rate swap contracts. The risk associated with these transactions is mitigated by simultaneously entering into similar transactions having essentially offsetting terms with a third party. In addition, the Company executes interest rate swaps with third parties in order to hedge the interest rate risk of short-term FHLB advances. Currency Forward Contracts. At June 30, 2023 and December 31, 2022, the Company had no currency forward contracts in place with commercial banking customers. Interest Rate Swaps. At June 30, 2023 and December 31, 2022, the Company had 70 and 54 interest rate swaps in place with commercial banking customers executed by offsetting interest rate swaps with third parties, with aggregated notional amounts of $256.2 million and $205.0 million, respectively. These derivatives are not designated as hedges and are not speculative. These interest rate swaps do not meet hedge accounting requirements. At June 30, 2023 and December 31, 2022, the Company had 18 and 20 interest rate swaps with notional amounts of $280.0 million and $290.0 million, respectively, hedging certain FHLB advances. These interest rate swaps meet the cash flow hedge accounting requirements. Interest rate swaps designated as cash flow hedges involve the receipt of variable amounts from a counter-party in exchange for the Company making fixed-rate payments over the life of the agreements without the exchange of the underlying notional amount. At both June 30, 2023 and December 31, 2022, the Company had two interest rate swaps hedged against pools of floating rate commercial loans with notional amounts totaling $100.0 million. These swaps meet the cash flow hedge accounting requirements. Interest rate swaps designated as cash flow hedges involve the receipt of variable amounts from a counter-party in exchange for the Company making fixed-rate payments over the life of the agreements without the exchange of the underlying notional amount. At June 30, 2023, the Company had five interest rate fair value swaps with notional amounts totaling $400.0 million. These swaps meet the cash flow hedge accounting requirements. The Company is exposed to changes in the fair value of certain of its fixed-rate pools of assets due to changes in benchmark interest rates. The Company uses interest rate swaps to manage its exposure to changes in fair value on these instruments attributable to changes in the designated benchmark interest rate, the Secured Overnight Financing Rate ("SOFR"). At December 31, 2022, the Company did not have any fair value swaps. 16. Derivatives and Hedging Activities (continued) Interest rate swaps designated as fair value hedges involve the payment of fixed-rate amounts to a counterparty in exchange for the Company receiving variable-rate payments over the life of the agreements without the exchange of the underlying notional amount. For the three and six months ended June 30, 2023, the Company recorded hedge ineffectiveness associated with these contracts totaling $23,000 and $27,000, respectively. For the three and six months ended June 30, 2022, the Company did not record any hedge ineffectiveness associated with these contracts. The tables below present the fair value of the Company’s derivative financial instruments as well as their classification in the Consolidated Statements of Financial Condition at June 30, 2023 and December 31, 2022: June 30, 2023 Asset Derivative Liability Derivative Consolidated Statements of Financial Condition Fair Value Consolidated Statements of Financial Condition Fair Value (In thousands) Derivatives: Interest rate products - designated hedges Other Assets $ 11,032 Other Liabilities $ 2,778 Interest rate products - non-designated hedges Other Assets 16,042 Other Liabilities 15,932 Total derivative instruments $ 27,074 $ 18,710 December 31, 2022 Asset Derivative Liability Derivative Consolidated Statements of Financial Condition Fair Value Consolidated Statements of Financial Condition Fair Value (In thousands) Derivatives: Interest rate products - designated hedges Other Assets $ 4,290 Other Liabilities $ 3,918 Interest rate products - non-designated hedges Other Assets 15,466 Other Liabilities 15,154 Total derivative instruments $ 19,756 $ 19,072 For the three months ended June 30, 2023 and 2022, (losses) gains of $(9,000) and $226,000, respectively, were recorded for changes in fair value of interest rate swaps with third parties. For the six months ended June 30, 2023 and 2022, (losses) gains of $(202,000) and $475,000, respectively, were recorded for changes in fair value of interest rate swaps with third parties. At June 30, 2023 and December 31, 2022, accrued interest was $461,000 and $22,000. The Company has agreements with counterparties that contain a provision that if the Company defaults on any of its indebtedness, including default where repayment of the indebtedness has not been accelerated by the lender, then the Company could also be declared in default of its derivative obligations. At June 30, 2023, the termination value of derivatives in a net liability position, which includes accrued interest, was $8.4 million. The Company normally has collateral posting thresholds with certain of its derivative counterparties, but as of June 30, 2023 has no posted collateral against its obligations under these agreements. 16. Derivatives and Hedging Activities (continued) Fair Value Hedges of Interest Rate Risk. The Company is exposed to changes in the fair value of certain of its fixed-rate pools of assets due to changes in benchmark interest rates. The Company uses interest rate swaps to manage its exposure to changes in fair value on these instruments attributable to changes in the designated benchmark interest rate, SOFR. Interest rate swaps designated as fair value hedges involve the payment of fixed-rate amounts to a counterparty in exchange for the Company receiving variable-rate payments over the life of the agreements without the exchange of the underlying notional amount. For derivatives designated and that qualify as fair value hedges, the gain or loss on the derivative as well as the offsetting gain or loss on the hedged item attributable to the hedged risk are recognized in interest income. At June 30, 2023, the following amounts were recorded on the Consolidated Statements of Financial Condition related to cumulative basis adjustment for fair value hedges: Carrying Amount of Hedged Assets/(Liabilities) Cumulative Amount of Fair Value Hedging Adjustment included in the Carrying Amount of Hedged Assets/(Liabilities) At June 30, 2023 (In thousands) Fair value interest rate products $ 395,390 $ (4,610)

Revenue from Contract with Customer [Abstract]
Revenue Recognition	Revenue Recognition The Company's revenue includes net interest income on financial instruments and non-interest income. Most of the Company's revenue is not within the scope of Accounting Standards Codification Topic 606 which does not apply to revenue associated with financial instruments, including interest income on loans and securities, which comprise the majority of the Company's revenue. Revenue-generating activities that are within the scope of this guidance are components of non-interest income. These revenue streams can generally be classified as demand deposit account fees, title insurance fees, insurance agency income and other fees. The following table presents non-interest income, segregated by revenue streams in-scope and out-of-scope of Topic 606, for the three and six months ended June 30, 2023 and 2022. For the Three Months Ended June 30, For the Six Months Ended June 30, 2023 2022 2023 2022 (In thousands) Non-interest income In-scope of Topic 606: Demand deposit account fees $ 1,291 $ 1,449 $ 2,467 $ 2,619 Title insurance fees 624 1,035 1,211 1,992 Insurance agency income 40 45 77 45 Other non-interest income 2,448 2,106 4,964 4,139 Total in-scope non-interest income 4,403 4,635 8,719 8,795 Total out-of-scope non-interest income (4,949) 3,034 (1,191) 5,915 Total non-interest income $ (546) $ 7,669 $ 7,528 $ 14,710 Demand deposit account fees include monthly maintenance fees and service charges. These fees are generally derived as a result of either transaction-based or serviced-based services. The Company's performance obligation for these services is generally satisfied, and revenue recognized, at the time the transaction is completed, or the service rendered. Fees for these services are generally received from the customer either at the time of the transaction or monthly. 17. Revenue Recognition (continued) Title insurance fees are generally recognized at the time the transaction closes or when the service is rendered. RSI Insurance Agency, Inc. performs the function of an insurance intermediary, by introducing the policyholder and insurer for life and health, and property and casualty insurance, and is compensated by a commission fee for placement of an insurance policy. Commission and fees are generally recognized as of the effective date of the insurance policy. Commission revenues related to installment billings are recognized on the invoice date. Subsequent commission adjustments are recognized upon the receipt of notification from insurance companies concerning matters necessitating such adjustments. Other non-interest income includes check printing fees, traveler's check fees, gift card fees, branch service fees, overdraft fees, account analysis fees, other deposit related fees, wealth management related fee income which includes annuity fees, brokerage commissions, and asset management fees. Wealth management related fee income represent fees earned from customers as consideration for asset management and investment advisory services provided by a third party. The Company's performance obligation is generally satisfied monthly, and the resulting fees are recognized monthly based upon the month-end market value of the assets under management and the applicable fee rate. The Company does not earn performance-based incentives. The Company's performance obligation for these transaction-based services are generally satisfied, and related revenue recognized, at the time the transaction closes or when the service is rendered or a point in time when the service is completed. Also included in other fees are debit card and ATM fees which are transaction-based. Debit card revenue is primarily comprised of interchange fees earned when a customer's Company card is processed through a card payment network. ATM fees are largely generated when a Company cardholder uses a non-Company ATM, or a non-Company cardholder uses a Company ATM. The Company's performance obligation for these services is satisfied when the service is rendered. Payment is generally received at time of transaction or monthly. Out-of-scope non-interest income primarily consists of income from bank-owned life insurance, loan prepayment and servicing fees, net fees loan level swaps, gains and losses on the sale of loans and securities, credit card interchange income, and changes in the fair value of equity securities. None of these revenue streams are subject to the requirements of Topic 606.

Accounting Standards Update and Change in Accounting Principle [Abstract]
Acquisitions	Described below are the methods used to determine the fair values of the significant assets acquired and liabilities assumed in the RSI acquisition: Cash and cash equivalents . The estimated fair values of cash and cash equivalents approximate their stated face amounts, as these financial instruments are either due on demand or have short-term maturities. Debt securities available for sale . The estimated fair values of the debt securities were calculated utilizing Level 2 inputs. The majority of the acquired securities were fixed income instruments that are not quoted on an exchange but are traded in active markets. The prices for these instruments are obtained through an independent pricing service when available, or dealer market participants with whom the Company has historically transacted with for both purchases and sales of securities. The prices are derived from market quotations and matrix pricing. The fair value measurements consider observable data that may include dealer quotes, market spreads, cash flows, the U.S. Treasury yield curve, and the bond's terms and conditions, among other things. Management reviewed the data and assumptions used in pricing securities by its third party provider to ensure the highest level of significant inputs are derived from market observable data. Loans receivable . The acquired loan portfolio was segregated into pools for valuation purposes primarily based on loan type, non-accrual status, and credit risk rating. The estimated fair values were computed by discounting the expected cash flows from the respective pools. Cash flows were estimated by using valuation models that incorporated estimates of current key assumptions such as prepayment speeds, default rates, and loss severity rates. The process included: (1) projecting monthly principal and/or interest cash flows based on the contractual terms of the loans, including both maturity and contractual amortization; (2) adjusting projected cash flows for expected losses and prepayments, where appropriate; (3) developing a discount rate based on the relative risk of the cash flows, considering the loan type, liquidity risk, the maturity of the loans, servicing costs, and a required return on capital; and (4) discounting the projected cash flows to a present value, to arrive at the calculated value of the loans. The methods used to estimate the fair values of loans are extremely sensitive to the assumptions and estimates used. While management attempted to use assumptions and estimates that best reflected the acquired loan portfolios and current market conditions, a greater degree of subjectivity is inherent in the values than in those determined in active markets. Office properties and equipment, net . The fair value of land and buildings was estimated using current appraisals. Acquired equipment was not material. Buildings are amortized over their estimated useful lives. Equipment is amortized or depreciated over their estimated useful lives usually ranging from three Goodwill . Goodwill is not amortized for book purposes: however, it is reviewed at least annually for impairment and is not deductible for tax purposes. Core deposit intangibles . Core deposit intangibles ("CDI") are the measure of the value of non-maturity deposits in a business combination. The fair value of the CDI was calculated utilizing the cost savings approach, the expected cost savings attributable to the core deposits funding relative to an alternative source of funding, using a discounted cash flow present value methodology. Key inputs and assumptions utilized in the discounted cash flow present value methodology include core deposit balances and rates paid, the cost of an additional funding source, the aggregate life of deposits and truncation points, non-interest deposit costs, and the immediate deposit outflow assumption. 2. Acquisitions (continued) Deposits . The fair values of deposit liabilities with no stated maturity (i.e., non-interest-bearing and interest-bearing demand deposit accounts, money market and savings and club accounts) are equal to the carrying amounts payable on demand. The fair value of certificates of deposit represents contractual cash flows, discounted to present value using interest rates currently offered on deposits with similar characteristics and remaining maturities. Borrowings . The fair values of borrowings consisting of FHLB advances were estimated by discounting future cash flows using market discount rates for borrowings with similar characteristics, terms and remaining maturities.
Recent Accounting Pronouncements	Accounting Pronouncements Adopted In March 2022, the FASB issued ASU 2022-01, Derivatives and Hedging (Topic 815): Fair Value Hedging – Portfolio Layer Method . The purpose of this updated guidance is to further align risk management objectives with hedge accounting results on the application of the last-of-layer method, which was first introduced in ASU 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities. ASU 2022-01 is effective for public business entities for fiscal years beginning after December 15, 2022, with early adoption in the interim period, permitted. For entities who have already adopted ASU 2017-12, immediate adoption is allowed. ASU 2022-01 requires a modified retrospective transition method for basis adjustments in which the entity will recognize the cumulative effect of the change on the opening balance of each affected component of equity in the statement of financial position as of the date of adoption. The Company adopted this ASU on January 1, 2023 on a prospective basis; therefore, there was no impact to 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 . ASU 2022-02 addresses areas identified by the FASB as part of its post-implementation review of the credit losses standard (ASU 2016-13) that introduced the CECL model. The amendments eliminated the accounting guidance for troubled debt restructurings by creditors that have adopted the CECL model and enhanced the disclosure requirements for loan refinancing and restructurings made with borrowers experiencing financial difficulty. In addition, the amendments required a public business entity to disclose current period gross write-offs for financing receivables and net investment in leases by year of origination in the vintage disclosures. For entities that adopted ASU 2016-13, this ASU was effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. The Company adopted this pronouncement effective January 1, 2023. The update was applied on a prospective basis to disclosures and did not have a significant impact on the Company's consolidated financial statements. In June 2016, the FASB issued ASU 2016-13, Financial Instruments- Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments ("CECL") , further amended by ASU 2019-04, Codification Improvements to Topic 326, Financial Instruments-Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments . Topic 326 pertains to the measurement of credit losses on financial instruments. This update requires the measurement of all expected credit losses for financial instruments held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. Financial institutions and other organizations will now use forward-looking information to better determine their credit loss estimates. This update is intended to improve financial reporting by requiring timelier recording of credit losses on loans and other financial instruments held by financial institutions and other organizations. This update was effective for financial statements issued for fiscal years and interim periods beginning after December 15, 2019. The Company elected to defer the adoption of the CECL methodology until December 31, 2020 as permitted by the enacted Coronavirus Aid, Relief and Economic Security Act ("CARES Act"). In late December 2020, the Consolidated Appropriations Act, 2021 was enacted, and extended certain provisions of the CARES Act, which allowed the Company to extend the adoption of CECL until January 1, 2022. The Company elected to extend its adoption of CECL in accordance with this legislation, and adopted the above mentioned ASUs related to Financial Instruments -Credit Losses (Topic 326) using a modified retrospective approach. 5. Summary of Significant Accounting Policies (continued) Accounting Pronouncements Adopted (continued) The Company adopted ASU 2016-13 on January 1, 2022 for all financial assets measured at amortized cost and off-balance- sheet credit exposures. Results are presented under Accounting Standards Codification 326, Financial Instruments - Credit Losses.
Loans Receivable and Allowance for Credit Losses	On January 1, 2022, the Company adopted CECL (ASC Topic 326), which replaced the historical incurred loss methodology with an expected loss methodology. The loan portfolio segmentation was expanded to seven portfolio segments taking into consideration common loan attributes and risk characteristics, as well as historical reporting metrics and data availability. The Company made an accounting policy election to exclude accrued interest receivable from the amortized cost basis of loans receivable. Accrued interest receivable on loans receivable is reported as a component of accrued interest receivable in the Consolidated Statement of Financial Condition, which totaled $30.8 million and $29.4 million at June 30, 2023 and December 31, 2022, respectively, and is excluded from the estimate of credit losses. The allowance for credit losses on loans reflects management’s evaluation of the current expected credit losses in the loan portfolio. The Company maintains the allowance for credit losses through provisions for credit losses that are charged to income. Charge-offs against the allowance for credit losses are taken on loans where management determines that the collection of loan principal and interest is unlikely. Recoveries made on loans that have been charged-off are credited to the allowance for credit losses. Management estimates the allowance balance using relevant available information, from internal and external sources, related to past events, current conditions, and a reasonable and supportable forecast. Historical credit loss experience for both the Company and peers provides the basis for the estimation of expected credit losses, where observed credit losses are converted to probability of default rate through the use of segment-specific loss given default risk factors that convert default rates to loss severity based on industry-level, observed relationships between the two variables for each segment, primarily due to the nature of the underlying collateral. These risk factors were assessed for reasonableness against the Company’s own loss experience and adjusted in certain cases when the relationship between the Company’s historical default and loss severity deviate from that of the wider industry. The historical probability of default ("PD") curves, together with corresponding economic conditions, establish a quantitative relationship between economic conditions and loan performance through an economic cycle. Using the historical relationship between economic conditions and loan performance, management’s expectation of future loan performance is incorporated using an externally developed economic forecast. This forecast is applied over a period that management has determined to be reasonable and supportable. Beyond the period over which management can develop or source a reasonable and supportable forecast, the model will revert to long-term average economic conditions using a straight-line, time-based methodology. The Company's current forecast period is six quarters, with a four quarter reversion period to historical average macroeconomic factors. 9. Loans Receivable and Allowance for Credit Losses (continued) The allowance for credit losses is measured on a collective (pool) basis, with both a quantitative and qualitative analysis that is applied on a quarterly basis, when similar risk characteristics exist. The respective quantitative allowance for each segment is measured using an economic forecast, discounted cash flow modeling methodology in which distinct, segment-specific multi-variate regression models are applied to an external economic forecast. Under the discounted cash flows methodology, expected credit losses are estimated over the effective life of the loans by measuring the difference between the net present value of modeled cash flows and amortized cost basis. Contractual cash flows over the contractual life of the loans are the basis for modeled cash flows, adjusted for modeled defaults and expected prepayments and discounted at the loan-level effective interest rate. The contractual term excludes expected extensions, renewals, and modifications. After quantitative considerations, management applies additional qualitative adjustments so that the allowance for credit loss is reflective of the estimate of lifetime losses that exist in the loan portfolio at the balance sheet date. Portfolio segment is defined as the level at which an entity develops and documents a systematic methodology to determine its allowance for credit losses. Management developed segments for estimating loss based on type of borrower and collateral, which is generally based upon federal call report segmentation. The segments have been combined or sub-segmented as needed to ensure loans of similar risk profiles are appropriately pooled. The allowance for credit losses on loans individually analyzed for impairment is based upon loans that have been identified through the Company’s loan monitoring process. This process includes the review of delinquent, restructured, and charged-off loans. Management believes the primary risks inherent in the portfolio are a general decline in the economy, a decline in real estate market values, rising unemployment, and increases in interest rates in the absence of economic improvement. Any one or a combination of these events may adversely affect a borrower's ability to repay its loan, resulting in increased delinquencies and loan losses. Accordingly, the Company has recorded loan losses at a level which is estimated to represent the current risk in its loan portfolio. Management considers it important to maintain the ratio of the allowance for credit losses to total loans at an acceptable level considering the current composition of the loan portfolio.
Fair Value Measurements	Debt Securities Available for Sale, at Fair Value For debt securities available for sale, fair value was estimated using a market approach. The majority of these securities are fixed income instruments that are not quoted on an exchange but are traded in active markets. Prices for these instruments are obtained through third-party data service providers or dealer market participants with which the Company has historically transacted both purchases and sales of securities. Prices obtained from these sources include market quotations, matrix pricing and discounted cash flow pricing. Matrix pricing, a Level 2 input, is a mathematical technique used principally to value certain securities to a benchmark or to comparable securities. The Company evaluates the quality of Level 2 matrix pricing through comparison to similar assets with greater liquidity and evaluation of projected cash flows. Discounted cash flows, a Level 3 input, is estimated by discounting the expected future cash flows using the current rates for securities with similar credit ratings and similar remaining maturities. As the Company is responsible for the determination of fair value, it performs quarterly analysis on the prices received from the pricing service to determine whether the prices are reasonable estimates of fair value. Specifically, the Company compares the prices received from the pricing service to a secondary pricing source. Additionally, the Company compares changes in the reported market values and returns to relevant market indices to assess the reasonableness of the reported prices. The Company’s internal price verification procedures and review of fair value methodology documentation provided by independent pricing services has not historically resulted in an adjustment in the prices obtained from the pricing service. The Company may hold debt instruments issued by the U.S. government and U.S. government-sponsored agencies that are traded in active markets with readily accessible quoted market prices that are considered Level 1 inputs. The Company classifies the estimated fair value of its loan portfolio as Level 3. Equity Securities, at Fair Value The Company holds equity securities that are traded in active markets with readily accessible quoted market prices that are considered Level 1 inputs. A trust preferred security that is not traded in an active market and Federal Home Loan Mortgage Corporation ("FHLMC") and Federal National Mortgage Association ("FNMA") preferred stock are considered Level 2 instruments. In addition, Level 2 instruments include Atlantic Community Bankers Bank ("ACCB") stock, which is based on redemption at par value and can only be sold to the issuing ACBB or another institution that holds ACBB stock. 14. Fair Value Measurements (continued) Derivatives The Company records all derivatives included in other assets and liabilities on the Consolidated Statements of Financial Condition at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, whether the Company has elected to designate a derivative in a hedging relationship and apply hedge accounting, and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. See note 16 for disclosures related to the accounting treatment for derivatives. The fair value of the Company's derivatives is determined using discounted cash flow analysis using observable market-based inputs, which are considered Level 2 inputs. Individually Analyzed Collateral Dependent Loans/Impaired Loans The fair value of collateral dependent loans that are individually analyzed or were previously deemed impaired is measured based on the present value of expected future cash flows discounted at the loan's effective interest rate or, as a practical expedient, at the loan's observable market price or the fair value of the collateral if the loan is collateral dependent. For individually analyzed loans measured for impairment based on the fair value of the underlying collateral, fair value was estimated using a market approach. The Company measures the fair value of collateral underlying impaired loans primarily through obtaining independent appraisals that rely upon quoted market prices for similar assets in active markets. These appraisals include adjustments, on an individual case-by-case basis, to comparable assets based on the appraisers’ market knowledge and experience, as well as adjustments for estimated costs to sell between 6% and 8%. For non-collateral dependent loans, management estimates fair value using discounted cash flows based on inputs that are largely observable. The Company classifies these loans as Level 3 within the fair value hierarchy. Mortgage Servicing Rights, Net ("MSR's") Mortgage servicing rights are carried at the lower of cost or estimated fair value. The estimated fair value of MSRs is obtained through an analysis of future cash flows, incorporating assumptions that market participants would use in determining fair value including market discount rates, prepayments speeds, servicing income, servicing costs, default rates and other market driven data, including the market's perception of future interest rate movements. The prepayment speed and the discount rate are considered two of the most significant inputs in the model. A significant degree of judgment is involved in valuing the mortgage servicing rights using Level 3 inputs. The use of different assumptions could have a significant effect on this fair value estimate. Other Fair Value Disclosures The Company is required to disclose estimated fair value of financial instruments, both assets and liabilities on and off the balance sheet, for which it is practicable to estimate fair value. A description of the valuation methodologies used for those assets and liabilities not recorded at fair value on a recurring or non-recurring basis are set forth below. Cash and Cash Equivalents For cash and due from banks, federal funds sold and short-term investments, the carrying amount approximates fair value due to their nature and short-term maturities. Debt Securities Held to Maturity For debt securities held to maturity, fair value was estimated using a market approach. The majority of the Company’s securities are fixed income instruments that are not quoted on an exchange, but are traded in active markets. Prices for these instruments are obtained through third-party data service providers or dealer market participants with which the Company has historically transacted both purchases and sales of securities. Prices obtained from these sources include market quotations and matrix pricing. Matrix pricing, a Level 2 input, is a mathematical technique used principally to value certain securities to a benchmark or to comparable securities. The Company evaluates the quality of Level 2 matrix pricing through comparison to similar assets with greater liquidity and evaluation of projected cash flows. As the Company is responsible for the determination of fair value, it performs quarterly analysis on the prices received from the pricing service to determine whether the prices are reasonable estimates of fair value. Specifically, the Company compares the prices received from the pricing service to a secondary pricing source. Additionally, the Company compares changes in the reported market values and returns to relevant market indices to assess the reasonableness of the reported prices. The Company’s internal price verification procedures and review of fair value methodology documentation provided by independent pricing services has not historically resulted in an adjustment in the prices obtained from the pricing service. The Company also holds debt instruments issued by the U.S. government and U.S. government-sponsored agencies that are traded in active markets with readily accessible quoted market prices that are considered Level 1 inputs within the fair value hierarchy. Federal Home Loan Bank Stock ("FHLB") The fair value of FHLB stock is based on redemption at par value and can only be sold to the issuing FHLB, to other FHLBs, or to other member banks. As such, the Company's FHLB stock is recorded at cost, or par value, and is evaluated for impairment each reporting period by considering the ultimate recoverability of the investment rather than temporary declines in value. The Company classifies the estimated fair value as Level 2 within the fair value hierarchy. 14. Fair Value Measurements (continued) Loans Receivable Fair values are estimated for portfolios of loans with similar financial characteristics. Loans are segregated by type such as commercial mortgage, residential mortgage, commercial, construction, consumer, and other. Each loan category is further segmented into fixed and adjustable rate interest terms and into performing and non-performing categories. The fair value of performing loans was estimated using a combination of techniques, including a discounted cash flow model that utilizes a discount rate that reflects the Company's current pricing for loans with similar characteristics and remaining maturity, adjusted by an amount for estimated credit losses inherent in the portfolio at the balance sheet date. The rates take into account the expected yield curve, as well as an adjustment for prepayment risk, when applicable. The Company classifies the estimated fair value of its loan portfolio as Level 3. The fair value for significant non-performing loans was based on recent external appraisals of collateral securing such loans, adjusted for the timing of anticipated cash flows. The Company classifies the estimated fair value of its non-performing loan portfolio as Level 3. Deposits The fair value of deposits with no stated maturity, such as demand, money market, and savings and club deposits are payable on demand at each reporting date and classified as Level 2. The estimated fair value of certificates of deposit was based on the discounted value of contractual cash flows. The discount rate was estimated using the Company’s current rates offered for deposits with similar remaining maturities. The Company classifies the estimated fair value of its certificates of deposit portfolio as Level 2. Borrowings The fair value of borrowings was estimated by discounting future cash flows using rates available for debt with similar terms and maturities and is classified by the Company as Level 2 within the fair value hierarchy. Commitments to Extend Credit and Letters of Credit The fair value of commitments to extend credit and letters of credit was estimated using the fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreements and the present creditworthiness of the counter-parties. For fixed rate loan commitments, fair value also considers the difference between current levels of interest rates and the committed rates. The fair value estimates of commitments to extend credit and letters of credit are deemed immaterial. 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 limited markets exist 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 factors. 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 on and off-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. Other significant assets and liabilities that are not considered financial assets or liabilities include goodwill and intangible assets, deferred tax assets and liabilities, office properties and equipment, and bank-owned life insurance.
