Organization, Consolidation and Presentation of Financial Statements [Abstract]
BASIS OF PRESENTATION	BASIS OF PRESENTATION The accompanying unaudited consolidated interim financial statements were prepared in accordance with instructions for Form 10-Q and, therefore, do not include all disclosures required by accounting principles generally accepted in the United States of America for complete presentation of financial statements. In the opinion of management, the consolidated financial statements contain all adjustments (consisting only of normal recurring accruals) necessary to present fairly the consolidated statements of condition of Camden National Corporation (the "Company") as of September 30, 2023 and December 31, 2022, the consolidated statements of income for the three and nine months ended September 30, 2023 and 2022, the consolidated statements of comprehensive income (loss) for the three and nine months ended September 30, 2023 and 2022, the consolidated statements of changes in shareholders' equity for the three and nine months ended September 30, 2023 and 2022, and the consolidated statements of cash flows for the nine months ended September 30, 2023 and 2022. The consolidated financial statements include the accounts of the Company and Camden National Bank (the "Bank"), a wholly-owned subsidiary of the Company (which includes the consolidated accounts of Healthcare Professional Funding Corporation ("HPFC") and Property A, Inc.). All intercompany accounts and transactions have been eliminated in consolidation. Assets held by the Bank in a fiduciary capacity, through Camden National Wealth Management, a division of the Bank, are not assets of the Company and, therefore, are not included in the consolidated statements of condition. The Company also owns 100% of the common stock of Camden Capital Trust A and Union Bankshares Capital Trust I. These entities are unconsolidated subsidiaries of the Company. Certain reclassifications may have been made to prior period amounts to conform to the current period presentation. Any such reclassifications did not impact net income or shareholders' equity as previously reported. Net income reported for the three and nine months ended September 30, 2023, is not necessarily indicative of the results that may be expected for the full year. The information in this report should be read in conjunction with the consolidated financial statements and accompanying notes included in the Company's Annual Report on Form 10-K for the year ended December 31, 2022. The acronyms, abbreviations and definitions identified below are used throughout this Form 10-Q, including Part I. "Financial Information" and Part II.

RECENT ACCOUNTING PRONOUNCEMENT

RECENT ACCOUNTING PRONOUNCEMENTS	9 Months Ended
	Sep. 30, 2023
Accounting Standards Update and Change in Accounting Principle [Abstract]
RECENT ACCOUNTING PRONOUNCEMENTS	RECENT ACCOUNTING PRONOUNCEMENTS The Company adopted and updated its accounting policies for the following accounting standards that have been applied to the Company's interim consolidated financial statements for the three and nine months ended September 30, 2023: ASU No. 2022-01, Derivatives and Hedging ( Topic 815): Fair Value Hedging - Portfolio Layer Method ("ASU 2022-01"). The FASB issued ASU 2022-01 to amend ASU 2017-12, which was adopted by the Company in 2018. This amendment renames the "last-of-layer" method to the "portfolio layer" method, permits non-repayable financial assets to be included in a closed portfolio hedged using the portfolio layer method, and provides additional guidance for entities that apply the portfolio layer method of hedge accounting in accordance with Topic 815. The Company adopted ASU 2022-01, as amended, effective January 1, 2023 and leveraged the "portfolio layer" method to enter into interest rate swaps to hedge fixed-rate residential mortgages during the nine months ended September 30, 2023. There was no impact to the Company's consolidated financial statements upon adoption. Refer to Note 8 of the consolidated financial statements for further details. ASU No. 2022-02, Financial Instruments - Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures ("ASU 2022-02"). The FASB issued ASU 2022-02 to provide new guidance on TDRs and charge-offs for entities that have adopted ASU 2016-13. The Company adopted ASU 2022-02 effective January 1, 2023 on a prospective basis, and upon adoption there was no impact to the consolidated financial statements. The adoption of ASU 2022-02 eliminates the accounting and disclosure requirements for TDRs, including the requirement to measure the allowance using a discounted cash flow ("DCF") methodology. Beginning January 1, 2023, the Company no longer establishes a specific reserve for newly modified loans to borrowers experiencing financial difficulty. Instead, these modifications are included in their respective segments, and the ACL is calculated utilizing models that consider the borrowers' probability of default, loss given default and exposure at default. ASU 2022-02 also requires disclosure of modifications of loans to borrowers experiencing financial difficulty if the modification involves principal forgiveness, an interest rate reduction, an other-than-insignificant payment delay, a term extension, or a combination of any of these types of modifications. Additionally, ASU 2022-02 requires the disclosure of current period gross charge-offs by year of loss origination (vintage) which are required to be applied prospectively as of January 1, 2023, the Company's date of adoption. Refer to Note 4 of the consolidated financial statements for further details. The following provides a brief description of recently issued accounting pronouncements that have yet to be adopted by the Company: ASU No. 2023-02, Investments - Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method ("ASU 2023-02"). The FASB issued ASU 2023-02 to permit reporting entities to elect to account for tax equity investments, regardless of the tax credit program from which the income tax credits are received, using the proportional amortization method if certain conditions are met. Under the proportional amortization method, the initial cost of the investment is amortized in proportion to the income tax credits or other tax benefits received. ASU 2023-02 is effective for interim and annual periods beginning after December 15, 2023. Although the Company continues to evaluate the potential effects of ASU 2023-02, it does not expect the adoption of ASU 2023-02 to have a material impact on its consolidated financial statements.

These securities are held in a rabbi trust account and invested in mutual funds. The trading securities will be used for future payments associated with the Company's deferred compensation plan for eligible employees and directors. AFS Debt Securities AFS debt securities are reported on the Company's consolidated statements of condition at fair value. The following table summarizes the amortized cost, estimated fair value, and unrealized gains (losses) of AFS debt securities, as of the dates indicated: (In thousands) Amortized Unrealized Unrealized Fair September 30, 2023 Obligations of states and political subdivisions $ 42,652 $ — $ (1,983) $ 40,669 MBS issued or guaranteed by U.S. government-sponsored enterprises 521,794 19 (96,837) 424,976 CMO issued or guaranteed by U.S. government-sponsored enterprises 118,890 25 (14,099) 104,816 Corporate bonds 21,683 — (3,141) 18,542 Total AFS debt securities $ 705,019 $ 44 $ (116,060) $ 589,003 December 31, 2022 Obligations of states and political subdivisions $ 49,678 $ 11 $ (463) $ 49,226 MBS issued or guaranteed by U.S. government-sponsored enterprises 598,845 131 (84,957) 514,019 CMO issued or guaranteed by U.S. government-sponsored enterprises 122,760 — (13,413) 109,347 Corporate bonds 25,677 3 (2,397) 23,283 Total AFS debt securities $ 796,960 $ 145 $ (101,230) $ 695,875 As of September 30, 2023 and December 31, 2022, there was no allowance carried on AFS debt securities. In June of 2022, the Company transferred securities with a fair value of $520.3 million from AFS to HTM. The unrealized losses on the AFS debt securities at the time of transfer were $72.1 million, pre-tax, and were reported within AOCI. These unrealized losses are being amortized over the remaining life of the securities from AOCI into the HTM securities on the consolidated statements of condition. At September 30, 2023, the net unrealized losses on the transferred securities reported within AOCI were $48.2 million, net of a deferred tax asset of $13.2 million and at December 31, 2022 were $52.2 million, net of a deferred tax asset of $14.3 million. The net unrealized losses on AFS debt securities reported within AOCI (excluding the aforementioned securities transferred from AFS to HTM) at September 30, 2023 and December 31, 2022, were $91.1 million and $79.4 million, respectively, and were net of a deferred tax asset of $24.9 million and $21.7 million, respectively. The following table presents the Company's AFS debt securities with gross unrealized losses, for which an ACL has not been recorded, segregated by the length of time the securities have been in a continuous loss position, as of the dates indicated: Less Than 12 Months 12 Months or More Total (In thousands, except number of holdings) Number of Fair Unrealized Fair Unrealized Fair Unrealized September 30, 2023 Obligations of states and political subdivisions 82 $ 29,363 $ (1,272) $ 11,306 $ (711) $ 40,669 $ (1,983) MBS issued or guaranteed by U.S. government-sponsored enterprises 153 12,086 (274) 405,769 (96,563) 417,855 (96,837) CMO issued or guaranteed by U.S. government-sponsored enterprises 50 21,429 (172) 78,344 (13,927) 99,773 (14,099) Corporate bonds 12 2,705 (910) 15,837 (2,231) 18,542 (3,141) Total AFS debt securities 297 $ 65,583 $ (2,628) $ 511,256 $ (113,432) $ 576,839 $ (116,060) December 31, 2022 Obligations of states and political subdivisions 83 $ 42,276 $ (463) $ — $ — $ 42,276 $ (463) MBS issued or guaranteed by U.S. government-sponsored enterprises 175 118,290 (11,521) 381,355 (73,436) 499,645 (84,957) CMO issued or guaranteed by U.S. government-sponsored enterprises 64 47,340 (4,589) 62,007 (8,824) 109,347 (13,413) Corporate bonds 13 7,687 (384) 14,593 (2,013) 22,280 (2,397) Total AFS debt securities 335 $ 215,593 $ (16,957) $ 457,955 $ (84,273) $ 673,548 $ (101,230) For the three and nine months ended September 30, 2023 and 2022, the unrealized losses on the Company's AFS debt securities have not been recognized into income because management does not intend to sell and it is not more-likely-than-not it will be required to sell any of the AFS debt securities before recovery of its amortized cost basis. Furthermore, the unrealized losses were due to changes in interest rates and other market conditions and were not reflective of credit events. Agency-backed and government-sponsored enterprise securities have a long history with no credit losses, including during times of severe stress. The principal and interest payments on agency guaranteed debt is backed by the U.S. government. Government-sponsored enterprises similarly guarantee principal and interest payments and carry an implicit guarantee from the U.S. Department of the Treasury. Additionally, government-sponsored enterprise securities are exceptionally liquid, readily marketable, and provide a substantial amount of price transparency and price parity, indicating a perception of zero credit losses. AFS municipal debt holdings are comprised solely of high credit quality (rated A- or higher) state and municipal obligations. High credit quality state and municipal obligations have a history of zero to near-zero credit loss. Corporate bonds are primarily comprised of investment grade senior notes and senior subordinated notes of other financial institutions. The following table details the Company's sales of AFS debt securities for the periods indicated below: Three Months Ended Nine Months Ended (In thousands) 2023 2022 2023 2022 Proceeds from sales of investments $ 61,343 $ — $ 61,343 $ 8,723 Gross realized gains — — — 13 Gross realized losses (5,335) — (5,335) (22) At September 30, 2023 and December 31, 2022, total accrued interest receivable on AFS debt securities, which has been excluded from reported amortized cost basis on AFS debt securities, was $1.8 million and $1.9 million respectively, and was reported within other assets on the consolidated statements of condition. An allowance was not carried on the accrued interest receivable at either date. The amortized cost and estimated fair values of the Company's AFS debt securities by contractual maturity at September 30, 2023, are shown below.

Agency-backed and government-sponsored enterprise securities have a long history with no credit losses, including during times of severe stress. The principal and interest payments on agency-guaranteed debt is backed by the U.S. government. Government-sponsored enterprises similarly guarantee principal and interest payments and carry an implicit guarantee from the U.S. Department of the Treasury. Additionally, government-sponsored enterprise securities are exceptionally liquid, readily marketable, and provide a substantial amount of price transparency and price parity, indicating a perception of zero credit losses. HTM municipal debt holdings are comprised solely of high credit quality (rated A- or higher) state and municipal obligations. High credit quality state and municipal obligations have a history of zero to near-zero credit loss. Corporate bonds are primarily comprised of investment grade senior notes and senior subordinated notes of other financial institutions. For the three months ended September 30, 2023 and 2022, the Company did not record a provision for credit losses on its HTM debt security portfolio. For the nine months ended September 30, 2023 and 2022, the Company recorded a provision for credit losses on its HTM debt securities portfolio of $1.8 million and $0, respectively. The provision for credit losses recorded during the nine months ended September 30, 2023, was due to the write-off of a corporate bond issued by Signature Bank, which was designated as HTM and previously carried no ACL, resulting from Signature Bank's failure during the quarter ended March 31, 2023. Accordingly, the Company also wrote-off accrued interest receivable of $8,000 that was due from the Signature Bank corporate bond during the nine months ended September 30, 2023, the write-off was recorded as a reversal of interest income on the consolidated statements of income. The Company did not write-off any accrued interest for the nine months ended September 30, 2022. The Company evaluated its HTM debt securities with an amortized cost as of September 30, 2023 and December 31, 2022, and determined that the expected credit loss on its HTM portfolio was immaterial, and therefore it did not carry an ACL on the HTM portfolio at either date. As of September 30, 2023 and December 31, 2022, none of the Company's HTM debt securities were past due or on non-accrual status. For the three and nine months ended September 30, 2023 and 2022, the Company did not recognize any interest income on non-accrual HTM debt securities. At September 30, 2023 and December 31, 2022, total accrued interest receivable on HTM debt securities, which has been excluded from reported amortized cost basis of HTM debt securities, was $1.5 million and $1.7 million, respectively, and was reported within other assets on the consolidated statements of condition. An allowance was not carried on the HTM debt securities accrued interest receivable at either date. The amortized cost and estimated fair values of HTM debt securities by contractual maturity at September 30, 2023 are shown below. Expected maturities will differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties.

In addition, the Company makes loans for the construction of residential homes, multi-family properties and commercial real estate properties. The ability and willingness of borrowers to honor their repayment commitments is generally dependent on the level of overall economic activity within the geographic area and the general economy. SBA PPP Loans. Beginning in April 2020, the Company originated SBA PPP loans issued to qualifying businesses as part of the federal stimulus packages issued due to the COVID-19 pandemic. This program provided qualifying businesses a specialized, low-interest-rate loan by the U.S. Treasury Department and was administered by the SBA. SBA PPP loans provided borrower guarantees for lenders, as well as loan forgiveness incentives for borrowers that utilized the loan proceeds to cover employee compensation-related business operating costs, as well as certain other costs up to pre-established limits. Effective May 31, 2021, the SBA PPP loan program ended and the Company ceased originating loans under this program.

The Management Provision Committee supports the oversight efforts of the Audit Committee of the Board of Directors. • The Directors' Credit Committee of the Board of Directors reviews large credit exposures, monitors external loan review reports, reviews the lending authority for individual loan officers when required, and has approval authority and responsibility for all matters regarding the loan policy and other credit-related policies, including reviewing and monitoring asset quality trends, and concentration levels. • The Audit Committee of the Board of Directors has approval authority and oversight responsibility for the ACL adequacy and methodology. Segmentation. For purposes of determining the ACL on loans, the Company disaggregates its loans into portfolio segments. Each portfolio segment possesses unique risk characteristics that are considered when determining the appropriate level of allowance. As of September 30, 2023 and December 31, 2022, the Company's loan portfolio segments, as determined based on the unique risk characteristics of each, include the following: Commercial Real Estate - Non-Owner-Occupied. Non-owner-occupied commercial real estate loans are, in substance, all commercial real estate loans that are not categorized by the Company as owner-occupied commercial real estate loans. Non-owner-occupied commercial estate loans are investment properties in which the primary source for repayment of the loan by the borrower is derived from rental income associated with the property or the proceeds of the sale, refinancing, or permanent refinancing of the property. Non-owner-occupied commercial real estate loans consist of mortgage loans to finance investments in real property that may include, but are not limited to, multi-family residential, commercial/retail office space, industrial/warehouse space, hotels, assisted living facilities and other specific use properties. Construction projects are also included within the non-owner-occupied commercial real estate loan segment until they are completed. Commercial real estate loans typically are written with amortizing payment structures. Collateral values are determined based upon appraisals and evaluations in accordance with established policy guidelines. Maximum loan-to-value ratios at origination are governed by established policy and regulatory guidelines. Commercial Real Estate - Owner-Occupied. Generally, owner-occupied commercial real estate loans are properties that are owned and operated by the borrower, and the primary source for repayment is the cash flow from the ongoing operations and activities conducted by the borrower's business. Owner-occupied commercial real estate loans consist of mortgage loans to finance investments in real property that may include, but are not limited to, commercial/retail office space, restaurants, educational and medical practice facilities and other specific use properties. Commercial real estate loans are typically written with amortizing payment structures. Collateral values are determined based upon appraisals and evaluations in accordance with established policy guidelines. Maximum loan-to-value ratios at origination are governed by established policy and regulatory guidelines. Commercial. Commercial loans consist of revolving and term loan obligations extended to business and corporate enterprises for the purpose of financing working capital and/or capital investment. Collateral generally consists of pledges of business assets including, but not limited to, accounts receivable, inventory, plant and equipment, and/or real estate, if applicable. Commercial loans primarily are paid by the operating cash flow of the borrower. Commercial loans may be secured or unsecured. Residential Real Estate . Residential real estate loans held in the Company's loan portfolio are made to borrowers who demonstrate the ability to make scheduled payments with full consideration to underwriting factors. Borrower qualifications include favorable credit history combined with supportive income requirements and combined loan-to-value ratios within established policy guidelines. Collateral consists of mortgage liens on one- to four-family residences, including for investment purposes. Home Equity. Home equity loans and lines of credit are made to qualified individuals and are secured by senior or junior mortgage liens on owner-occupied one- to four-family homes, condominiums, or vacation homes. Each home equity loan has a fixed rate and is billed as equal payments comprised of principal and interest. Each home equity line of credit has a variable rate and is billed as interest-only payments during the draw period. At the end of the draw period, the home equity line of credit is billed as a percentage of the principal balance plus all accrued interest. Borrower qualifications include favorable credit history combined with supportive income requirements and combined loan-to-value ratios within established policy guidelines. Consumer. Consumer loan products include personal lines of credit and amortizing loans made to qualified individuals for various purposes such as education, auto loans, debt consolidation, personal expenses or overdraft protection.

The net decrease over this period was primarily driven by: • An increase of $954,000 in the ACL on loans for the residential real estate loan portfolio, primarily due to the deterioration in the economic outlook primarily for the Maine unemployment forecast over the Company's forecast period, as compared to December 31, 2022, and 3% loan growth in this loan portfolio during the forecast period; and • A combined $1.5 million decrease in commercial and commercial real estate non-owner occupied ACL on loans, primarily due to the forecasted improvement in U.S. and Maine GDP over the Company's forecast period, as compared to December 31, 2022. Additionally, charge offs for the commercial loans for the first nine months of 2023 decreased the ACL $1.1 million primarily due to a few large commercial relationships charges off that were considered to be isolated and not part of a trend for higher charge offs. Credit Concentrations The Company focuses on maintaining a well-balanced and diversified loan portfolio. Despite such efforts, it is recognized that credit concentrations may occasionally emerge as a result of economic conditions, changes in local demand, natural loan growth and runoff. To identify credit concentrations effectively, all commercial and commercial real estate loans are assigned Standard Industrial Classification codes, North American Industry Classification System codes, and state and county codes. Shifts in portfolio concentrations are monitored. As of September 30, 2023, the Company's total exposure to the lessors of nonresidential buildings' industry and lessors of residential buildings' industry were 13% and 12% of total loans and 33% and 28% of total commercial real estate loans, respectively. There were no other industry exposures exceeding 10% of the Company's total loan portfolio as of September 30, 2023. Credit Quality Indicators To further identify loans with similar risk profiles, the Company categorizes each portfolio segment into classes by credit risk characteristic and applies a credit quality indicator to each portfolio segment. The indicators for commercial real estate - non-owner-occupied and owner-occupied, commercial and residential real estate portfolio segments are represented by Grades 1 through 10 as outlined below. In general, risk ratings are adjusted periodically throughout the year as updated analysis and review warrants. This process may include, but is not limited to, annual credit and loan reviews, periodic reviews of loan performance metrics, such as delinquency rates, and quarterly reviews of adversely risk rated loans. The Company uses the following definitions when assessing grades for the purpose of evaluating the risk and adequacy of the ACL on loans: • Grade 1 through 6 — Grades 1 through 6 represent groups of loans that are not subject to adverse criticism as defined in regulatory guidance. Loans in these groups exhibit characteristics that represent low to moderate risks, which is measured using a variety of credit risk criteria, such as cash flow coverage, debt service coverage, balance sheet leverage, liquidity, management experience, industry position, prevailing economic conditions, support from secondary sources of repayment and other credit factors that may be relevant to a specific loan. In general, these loans are supported by properly margined collateral and guarantees of principal parties. • Grade 7 — Loans with potential weakness (Special Mention) . Loans in this category are currently protected based on collateral and repayment capacity and do not constitute undesirable credit risk, but have potential weakness that may result in deterioration of the repayment process at some future date. This classification is used if a negative trend is evident in the obligor’s financial situation. Special mention loans do not sufficiently expose the Company to warrant adverse classification. • Grade 8 — Loans with definite weakness (Substandard) . Loans classified as substandard are inadequately protected by the current sound worth and paying capacity of the obligor or by collateral pledged. Borrowers experience difficulty in meeting debt repayment requirements. Deterioration is sufficient to cause the Company to look to the sale of collateral. • Grade 9 — Loans with potential loss (Doubtful) . Loans classified as doubtful have all the weaknesses inherent in the substandard grade with the added characteristic that the weaknesses make collection or liquidation of the loan in full highly questionable and improbable. The possibility of some loss is extremely high, but because of specific pending factors that may work to the advantage and strengthening of the asset, its classification as an estimated loss is deferred until its more exact status may be determined. • Grade 10 — Loans with definite loss (Loss) . Loans classified as loss are considered uncollectible. The loss classification does not mean that the asset has absolutely no recovery or salvage value, but rather that it is not practical or desirable to defer writing off the asset because recovery and collection time may be protracted. The Company periodically reassesses asset quality indicators to reflect appropriately the risk composition of the Company’s loan portfolio. Home equity and consumer loans are not individually risk rated, but rather analyzed as groups taking into account delinquency rates and other economic conditions which may affect the ability of borrowers to meet debt service requirements, including interest rates and energy costs. Performing loans include loans that are current and loans that are past due less than 90 days. Loans that are past due over 90 days and non-accrual loans, including TDRs prior to adoption of ASU 2022-02, are considered non-performing.

A loan is placed on non-accrual status when the financial condition of the borrower is deteriorating, payment in full of both principal and interest is not expected as scheduled, or principal or interest has been in default for 90 days or more. Exceptions may be made if the asset is secured by collateral sufficient to satisfy both the principal and accrued interest in full and collection is reasonably assured. When one loan to a borrower is placed on non-accrual status, all other loans to the borrower are re-evaluated to determine if they should also be placed on non-accrual status. All previously accrued and unpaid interest is reversed at this time. A loan will return to accrual status when collection of principal and interest is assured and the borrower has demonstrated timely payments of principal and interest for a reasonable period, generally at least six months. Unsecured loans, however, are not normally placed on non-accrual status because they are generally charged-off once their collectability is in doubt. The following is a loan aging analysis by portfolio segment (including loans past due over 90 days and non-accrual loans) and loans past due over 90 days and accruing as of the following dates: (In thousands) 30-59 Days 60-89 Days 90 Days or Greater Total Current Total Loans Loans > 90 September 30, 2023 Commercial real estate - non-owner-occupied $ 45 $ — $ 92 $ 137 $ 1,349,326 $ 1,349,463 $ — Commercial real estate - owner-occupied — 142 — 142 303,683 303,825 Commercial 1,975 820 515 3,310 396,721 400,031 — Residential real estate 507 527 1,024 2,058 1,750,343 1,752,401 — Home equity 585 14 281 880 232,572 233,452 — Consumer 30 6 7 43 19,198 19,241 — Total $ 3,142 $ 1,509 $ 1,919 $ 6,570 $ 4,051,843 $ 4,058,413 $ — December 31, 2022 Commercial real estate - non-owner-occupied $ 267 $ — $ 11 $ 278 $ 1,292,165 $ 1,292,443 $ — Commercial real estate - owner-occupied 55 — 47 102 332,392 332,494 — Commercial 667 134 640 1,441 428,690 430,131 — Residential real estate 852 186 524 1,562 1,698,704 1,700,266 — Home equity 357 — 171 528 233,900 234,428 — Consumer 23 11 — 34 20,557 20,591 — Total $ 2,221 $ 331 $ 1,393 $ 3,945 $ 4,006,408 $ 4,010,353 $ — The following table presents the amortized cost basis of loans on non-accrual status (including non-accruing TDRs prior to adoption of ASU 2022-02) by portfolio segment as of the dates indicated: September 30, December 31, (In thousands) Non-Accrual Loans With an Allowance Non-Accrual Loans Without an Allowance Total Non-Accrual Loans Non-Accrual Loans With an Allowance Non-Accrual Loans Without an Allowance Total Non-Accrual Loans Commercial real estate - non-owner-occupied $ 83 $ 9 $ 92 $ — $ 11 $ 11 Commercial real estate - owner-occupied — — — — 46 46 Commercial 978 105 1,083 415 300 715 Residential real estate 1,943 832 2,775 1,314 419 1,733 Home equity 570 63 633 421 65 486 Consumer 41 — 41 — — — Total $ 3,615 $ 1,009 $ 4,624 $ 2,150 $ 841 $ 2,991 The following table presents the amortized cost basis of collateral-dependent non-accrual loans (including non-accruing TDRs prior to adoption of ASU 2022-02) by portfolio segment and collateral type, as of the dates indicated: September 30, December 31, Collateral Type Total Collateral -Dependent Collateral Type Total Collateral -Dependent (In thousands) Real Estate General Business Assets Real Estate General Business Assets Residential real estate $ 144 $ — $ 144 $ 387 $ — $ 387 Total $ 144 $ — $ 144 $ 387 $ — $ 387 Collateral-dependent loans are loans for which repayment is expected to be provided substantially by the underlying collateral and there are no other available and reliable sources of repayment. Interest income that would have been recognized if loans on non-accrual status had been current in accordance with their original terms is estimated to have been $34,000 and $30,000 for the three months ended September 30, 2023 and 2022, respectively. For the nine months ended September 30, 2023 and 2022, the interest income that is estimated to have been recognized if loans on non-accrual status had been current in accordance with their original terms was $84,000 and $115,000, respectively. The Company's policy is to reverse previously recorded interest income when a loan is placed on non-accrual. As a result, the Company did not record any interest income on its non-accruals for the three or nine months ended September 30, 2023 and 2022. At September 30, 2023 and December 31, 2022, total accrued interest receivable on loans, which has been excluded from reported amortized cost basis on loans, was $11.6 million and $8.9 million, respectively, and reported within other assets on the consolidated statements of condition. An allowance was not carried on the accrued interest receivable at either date. Loan Modifications for Borrowers Experiencing Financial Difficulty Effective January 1, 2023, the Company adopted prospectively ASU No. 2022-02, Financial Instruments - Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures ("ASU 2022-02"). ASU 2022-02 provided guidance that eliminated the recognition and measurement of TDRs. Following the adoption of this guidance, the Company evaluates all loan modifications made to borrowers experiencing financial difficulty according to the accounting guidance for loan refinancing and restructuring to determine whether such loan modification should be accounted for as a new loan or a continuation of the existing loan. Our loan modifications for borrowers experiencing financial difficulty are generally accounted for as a continuation of the existing loan. The Company offers several types of loans and receivables modification programs to borrowers experiencing financial difficulty, primarily interest rate reductions and term extensions. In such instances, the Company may modify loans and receivables with the intention to minimize future losses and improve collectability, while providing customers with temporary or permanent financial relief. There were no modified loans that required disclosure for the three and nine months ended September 30, 2023. TDR Disclosures Prior to Adoption of ASU 2022-02 Prior to the Company's adoption of ASU 2022-02, which became effective for the Company on January 1, 2023, TDRs consisted of loans where the Company, for economic or legal reasons related to the borrower’s financial difficulties, granted a concession to the borrower that it would not otherwise consider. TDRs typically involved term modifications or a reduction of either interest or principal. Once such an obligation has been restructured, it will remain a TDR until paid in full, or until the loan is again restructured at current market rates and no concessions are granted. The specific reserve allowance was determined by discounting the total expected future cash flows from the borrower at the original loan interest rate, or if the loan is currently collateral-dependent, using net realizable value, which was obtained through independent appraisals and internal evaluations. The following is a summary of TDRs prior to adoption of ASU 2022-02, by portfolio segment, and the associated specific reserve included within the ACL as of December 31, 2022: (In thousands, except number of contracts) Number of Contracts Recorded Investment Specific Reserve Commercial real estate - owner-occupied 1 $ 113 $ 50 Commercial — — — Residential real estate 18 2,208 307 Consumer and home equity 3 245 9 Total 22 $ 2,566 $ 366 At December 31, 2022, the Company had performing and non-performing TDRs with a recorded investment balance of $2.1 million and $452,000, respectively.

REPURCHASE AGREEMENTS	REPURCHASE AGREEMENTS The Company can raise additional liquidity by entering into repurchase agreements at its discretion. In a security repurchase agreement transaction, the Company will generally sell a security, agreeing to repurchase either the same or a substantially identical security on a specified later date, at a greater price than the original sales price. The difference between the sale price and purchase price is the cost of the proceeds, which is recorded within interest on borrowings on the consolidated statements of income. The securities underlying the agreements are delivered to counterparties as collateral for the repurchase obligations. Because the securities are treated as collateral and the agreement does not qualify for a full transfer of effective control, the transactions do not meet the criteria to be classified as sales, and are therefore considered secured borrowing transactions for accounting purposes. Payments on such borrowings are interest only until the scheduled repurchase date. In a repurchase agreement the Company is subject to the risk that the purchaser may default at maturity and not return the securities underlying the agreements. In order to minimize this potential risk, the Company either deals with established firms when entering into these transactions, or with customers whose agreements stipulate that the securities underlying the agreement are not delivered to the customer and instead are held in segregated safekeeping accounts by the Company's safekeeping agents. The table below sets forth information regarding the Company’s repurchase agreements accounted for as secured borrowings and types of collateral as of the dates indicated: (In thousands) September 30, December 31, Customer Repurchase Agreements (1)(2) : Mortgage-backed securities issued or guaranteed by U.S. government-sponsored enterprises $ 177,453 $ 99,105 Collateralized mortgage obligations issued or guaranteed by U.S. government-sponsored enterprises 32,687 94,328 Obligations of states and political subdivisions — 3,018 Total $ 210,140 $ 196,451 (1) Presented within short-term borrowings on the consolidated statements of condition. (2) All customer repurchase agreements mature continuously or overnight for the dates indicated. At September 30, 2023 and December 31, 2022, certain customers held CDs totaling $617,000 and $616,000, respectively, that were collateralized by CMO and MBS securities that were overnight repurchase agreements. Certain counterparties monitor collateral, and may request additional collateral to be posted from time to time.

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES Commitments In the normal course of business, the Company is a party to both on- and off-balance sheet financial instruments involving, to varying degrees, elements of credit risk and interest rate risk in addition to the amounts recognized in the consolidated statements of condition. The following is a summary of the Company's contractual off-balance sheet commitments as of the dates indicated: (In thousands) September 30, December 31, Commitments to extend credit $ 741,482 $ 817,772 Standby letters of credit 5,880 6,801 Total $ 747,362 $ 824,573 The Company’s commitments to extend credit from its lending activities do not necessarily represent future cash requirements since certain of these instruments may expire without being funded and others may not be fully drawn upon. These commitments are subject to the Company’s credit approval process, including an evaluation of the customer’s creditworthiness and related collateral requirements. Commitments generally have fixed expiration dates or other termination clauses. Standby letters of credit are conditional commitments issued to guarantee the performance of a borrower to a third party. In the event of nonperformance by the borrower, the Company would be required to fund the commitment and would be entitled to the underlying collateral, if applicable, which generally consists of pledges of business assets including, but not limited to, accounts receivable, inventory, plant and equipment, and/or real estate. The maximum potential future payments are limited to the contractual amount of the commitment. The Company establishes an ACL on off-balance sheet credit exposures on its contractual off-balance sheet commitments, except those that are unconditionally cancellable by the Company. As of September 30, 2023 and December 31, 2022, the ACL on off-balance sheet credit exposures was $2.7 million and $3.3 million, respectively. The ACL on off-balance sheet credit exposure was presented within accrued interest and other liabilities on the consolidated statements of condition. For the three months ended September 30, 2023 and 2022, the (credit) provision for credit losses on off-balance sheet credit exposures was ($118,000) and $251,000, respectively. For the nine months ended September 30, 2023 and 2022, the (credit) provision for credit losses on off-balance sheet credit exposures was ($595,000) and $246,000, respectively. Legal Contingencies In the normal course of business, the Company and its subsidiaries are subject to pending and threatened litigation, claims investigations and legal and administrative cases and proceedings. Although the Company is not able to predict the outcome of such actions, after reviewing pending and threatened actions with counsel, management believes that, based on the information currently available, the outcome of such actions, individually or in the aggregate, will not have a material adverse effect on the Company’s consolidated financial statements. Reserves are established for legal claims only when losses associated with the claims are judged to be probable, and the loss can be reasonably estimated. Assessments of litigation exposure are difficult because they involve inherently unpredictable factors including, but not limited to: whether the proceeding is in the early stages; whether damages are unspecified, unsupported, or uncertain; whether there is a potential for punitive or other pecuniary damages; whether the matter involves legal uncertainties, including novel issues of law; whether the matter involves multiple parties and/or jurisdictions; whether discovery has begun or is not complete; whether meaningful settlement discussions have commenced; and whether the lawsuit involves class allegations. In many lawsuits and arbitrations, it is not possible to determine whether a liability has been incurred or to estimate the ultimate or minimum amount of that liability until the case is close to resolution, in which case a reserve will not be recognized until that time. Assessments of class action litigation, which is generally more complex than other types of litigation, are particularly difficult, especially in the early stages of the proceeding when it is not known whether a class will be certified or how a potential class, if certified, will be defined. As a result, the Company may be unable to estimate reasonably possible losses with respect to every litigation matter it faces. The Company did not have any material loss contingencies that were provided for and/or that are required to be disclosed as of September 30, 2023 and December 31, 2022, respectively.

DERIVATIVES AND HEDGING

Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVES AND HEDGING	DERIVATIVES AND HEDGINGThe Company is exposed to certain risk arising from both its business operations and economic conditions. The Company principally manages its exposures to a wide variety of business and operational risks through management of its core business activities. The Company manages economic risks, including interest rate, liquidity, and credit risk primarily by managing the amount, sources, and duration of its assets and liabilities and the use of derivative financial instruments. Specifically, the Company enters into derivative financial instruments to manage exposures that arise from business activities that result in the receipt or payment of future known and uncertain cash amounts, the value of which are determined by interest rates. The Company’s credit derivatives result from loan participation arrangements, and therefore are not used to manage interest rate risk in the Company’s assets or liabilities. Derivatives Designated as Hedging Instruments - Hedges of Interest Rate Risk Interest Rate Contracts - Cash Flow Hedges. The Company’s objectives in using interest rate derivatives are to add stability to interest income and expense and to manage its exposure to interest rate movements. To accomplish this objective, the Company primarily uses interest rate swaps as part of its interest rate risk management strategy. Interest rate swaps designated as cash flow hedges involve the receipt of variable amounts from a counterparty in exchange for the Company making fixed rate payments or the receipt of fixed rate amounts from a counterparty in exchange for the Company making variable-rate payments over the life of the agreements without exchange of the underlying notional amount. For the three and nine months ended September 30, 2023 and 2022, such derivatives were used to hedge the variable cash flows associated with existing variable-rate assets or liabilities or forecasted issuances of debt. For derivatives designated, and that qualify as, cash flow hedges of interest rate risk, the gain or loss on the derivative is recorded in AOCI and subsequently is reclassified into interest expense or interest income in the same period(s) during which the hedged transaction affects earnings. Amounts reported in AOCI related to derivatives will be reclassified to interest expense or interest income as interest payments are made or received on the Company’s variable-rate liabilities or assets. The Company estimates that an additional $3.5 million will be reclassified as a decrease to interest expense and an additional $2.6 million will be reclassified as a decrease to interest income over the next 12 months. Interest Rate Contracts - Fair Value Hedges. Derivatives designated as fair value hedges are utilized to mitigate the risk of changes in the fair values of recognized assets and liabilities. The Company uses interest rate contracts in this manner to manage its exposure to changes in the fair value of hedged items caused by changes in interest rates. Changes in the fair value of the derivatives and changes in the fair value of the hedged item due to changes in the hedged risk are recognized in earnings in the same line item. If a hedge is terminated, but the hedged item was not derecognized, all remaining adjustments to the carrying amount of the hedged item are amortized over a period that is consistent with the amortization of other discounts or premiums associated with the hedged item. Derivatives not Designated as Hedges Customer Loan Swaps. Derivatives not designated as hedges are not speculative and result from a service the Company provides to certain customers. The Company executes interest rate swaps with commercial banking customers to facilitate their respective risk management strategies. Those interest rate swaps are simultaneously hedged by offsetting derivatives that the Company executes with a third party, such that the Company minimizes its net risk exposure resulting from such transactions. As the interest rate derivatives associated with this program do not meet the strict hedge accounting requirements, changes in the fair value of both the customer derivatives and the offsetting derivatives are recognized directly in earnings. Fixed Rate Mortgage Interest Rate Lock Commitments. As part of the origination process of a residential loan, the Company may enter into rate lock agreements with its borrower, which is considered an interest rate lock commitment. If the Company intends to sell the loan upon origination, it will account for the interest rate lock commitment as a derivative. Forward Delivery Commitments. The Company typically enters into a forward delivery commitment with a secondary market investor, which has been approved by the Company within its normal governance process, at the onset of the loan origination process. The Company may enter into these arrangements with the secondary market investors on a "best effort" or "mandatory delivery" basis. The Company's normal practice is typically to enter into these arrangements on a "best effort" basis. The Company enters into these arrangements with the secondary market investors to manage its interest rate exposure. The Company accounts for the forward delivery commitment as a derivative upon origination of a loan identified as held for sale. Risk Participation Agreements. The Company’s existing credit derivatives result from participations in or out of interest rate swaps provided by or to external lenders as part of loan participation arrangements, therefore, are not used to manage interest rate risk in the Company’s assets or liabilities. Derivatives not designated as hedges are not speculative and result from a service the Company provides to certain lenders which participate in loans.

Should a counterparty fail to perform under the terms of a derivative contract, the Company’s credit exposure on interest rate swaps is limited to the net positive fair value and accrued interest of all swaps with each counterparty. The Company seeks to minimize counterparty credit risk through credit approvals, limits, monitoring procedures, and obtaining collateral, where appropriate. As such, management believes the risk of incurring credit losses on derivative contracts with institutional counterparties is remote. The Company has agreements with its derivative counterparties that contain a provision where 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 on its derivative obligations. In addition, the Company also has agreements with certain of its derivative counterparties that contain a provision where if the Company fails to maintain its status as a well- capitalized institution, then the counterparty could terminate the derivative position(s) and the Company could be required to settle its obligations under the agreements. As of September 30, 2023 and December 31, 2022, the fair value of derivatives in a net liability position, which includes accrued interest but excludes any adjustment for non-performance risk, related to these agreements was $19.8 million and $14.8 million, respectively. As of September 30, 2023 and December 31, 2022, the Company has minimum collateral posting thresholds with certain of its derivative counterparties and has posted cash collateral of $0 and $0, respectively. If the Company had breached any of these provisions at September 30, 2023 or December 31, 2022, it could have been required to settle its obligations under the agreements at their termination value of $19.8 million and $14.8 million, respectively.

REGULATORY CAPITAL REQUIREMENTS

REGULATORY CAPITAL REQUIREMENTS	9 Months Ended
	Sep. 30, 2023
Broker-Dealer, Net Capital Requirement, SEC Regulation [Abstract]
REGULATORY CAPITAL REQUIREMENTS	REGULATORY CAPITAL REQUIREMENTS The Company and Bank are subject to various regulatory capital requirements administered by the FRB and the OCC. Failure to meet minimum capital requirements can result in mandatory and possible additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the Company’s consolidated financial statements. The Company and Bank are required to maintain certain levels of capital based on risk-adjusted assets. These capital requirements represent quantitative measures of their assets, liabilities and certain off-balance sheet items as calculated under regulatory accounting practices. The Company and Bank's capital classification is also subject to qualitative judgments by our regulators about components, risk weightings and other factors. The quantitative measures established to ensure capital adequacy require the Company and Bank to maintain minimum amounts and ratios of total capital, Tier 1 capital, and common equity Tier 1 capital to risk-weighted assets, and of Tier 1 capital to average assets, or the leverage ratio. These requirements apply to the Company on a consolidated basis. Under the current requirements, banking organizations must have a minimum total risk-based capital ratio of 8.0%, a minimum Tier 1 risk-based capital ratio of 6.0%, a minimum common equity Tier 1 risk-based capital ratio of 4.5%, and a minimum leverage ratio of 4.0% in order to be "adequately capitalized." In addition to these requirements, banking organizations must maintain a capital conservation buffer consisting of common Tier 1 equity in an amount above the minimum risk-based capital requirements for "adequately capitalized" institutions equal to 2.5% of total risk-weighted assets, resulting in a requirement for the Company and the Bank effectively to maintain common equity Tier 1, Tier 1 and total capital ratios of 7.0%, 8.5% and 10.5%, respectively. The Company and the Bank must maintain the capital conservation buffer to avoid restrictions on the ability to pay dividends, pay discretionary bonuses and to engage in share repurchases based on the amount of the shortfall and the institution's "eligible retained income" (that is, the greater of (i) net income for the preceding four quarters, net of distributions and associated tax effects not reflected in net income and (ii) average net income over the preceding four quarters). The Company and Bank's risk-based capital ratios exceeded regulatory requirements, including the capital conservation buffer, at September 30, 2023 and December 31, 2022, and the Bank's capital ratios met the requirements for it to be considered "well capitalized" under prompt corrective action provisions for each period. There were no changes to the Company or Bank's capital ratios that occurred subsequent to September 30, 2023 that would change the Company or Bank's regulatory capital categorization. The following table presents the Company and Bank's regulatory capital ratios at the periods indicated: September 30, Minimum Regulatory Capital Required for Capital Adequacy plus Capital Conservation Buffer Minimum Regulatory Provision to Be "Well Capitalized" December 31, Minimum Regulatory Capital Required for Capital Adequacy plus Capital Conservation Buffer Minimum Regulatory Provision to Be "Well Capitalized" (Dollars in thousands) Amount Ratio Amount Ratio Camden National Corporation: Total risk-based capital ratio $ 573,773 14.19 % 10.50 % 10.00 % $ 557,571 13.80 % 10.50 % 10.00 % Tier 1 risk-based capital ratio 534,696 13.22 % 8.50 % 6.00 % 517,385 12.81 % 8.50 % 6.00 % Common equity Tier 1 risk-based capital ratio (1) 491,696 12.16 % 7.00 % N/A 474,385 11.74 % 7.00 % N/A Tier 1 leverage capital ratio (1) 534,696 9.35 % 4.00 % N/A 517,385 9.22 % 4.00 % N/A Camden National Bank: Total risk-based capital ratio $ 544,093 13.48 % 10.50 % 10.00 % $ 525,346 13.03 % 10.50 % 10.00 % Tier 1 risk-based capital ratio 505,017 12.51 % 8.50 % 8.00 % 485,160 12.03 % 8.50 % 8.00 % Common equity Tier 1 risk-based capital ratio 505,017 12.51 % 7.00 % 6.50 % 485,160 12.03 % 7.00 % 6.50 % Tier 1 leverage capital ratio 505,017 8.84 % 4.00 % 5.00 % 485,160 8.65 % 4.00 % 5.00 % (1) “Minimum Regulatory Provisions to Be ‘Well Capitalized’” are not formally defined under applicable banking regulations for bank holding companies. In 2006 and 2008, the Company issued $43.0 million of junior subordinated debentures in connection with the issuance of trust preferred securities. Although the junior subordinated debentures are recorded as liabilities on the Company's consolidated statements of condition, the Company is permitted, in accordance with applicable regulation, to include the debentures within its calculation of risk-based capital, subject to certain limits. At September 30, 2023 and December 31, 2022, $43.0 million of the junior subordinated debentures were included in Tier 1 and Tier 2 capital for the Company. The Company and Bank's regulatory capital and risk-weighted assets fluctuate due to normal business, including profits and losses generated by the Company and Bank as well as changes to their asset mix. Of particular significance are changes within the Company and Bank's loan portfolio mix due to the differences in regulatory risk-weighting between retail and commercial loans. Furthermore, the Company and Bank's regulatory capital and risk-weighted assets are subject to change due to changes in GAAP and regulatory capital standards. The Company and Bank proactively monitor their regulatory capital and risk-weighted assets, and the impact of changes to their asset mix, and the impact of proposed and pending changes as a result of new and/or amended GAAP standards and regulatory changes.

Revenue from Contract with Customer [Abstract]
REVENUE FROM CONTRACTS WITH CUSTOMERS	REVENUE FROM CONTRACTS WITH CUSTOMERSA portion of the Company's non-interest income is derived from contracts with customers, and, as such, the revenue recognized depicts the transfer of promised goods or services to its customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The Company considers the terms of the contract and all relevant facts and circumstances when applying this guidance. The Company has disaggregated its revenue from contracts with customers into categories based on the nature of the revenue. The categorization of revenues from contracts with customers that are within the scope of ASC 606 closely aligns with the presentation of revenue categories presented within non-interest income on the consolidated statements of income. The following table presents the revenue streams within the scope of ASC 606 for the periods indicated: Location on Consolidated Statements of Income Three Months Ended September 30, Nine Months Ended September 30, (In thousands) 2023 2022 2023 2022 Debit card interchange income Debit card income $ 3,130 $ 3,234 $ 9,147 $ 9,371 Services charges on deposit accounts Service charges on deposit accounts 2,040 1,941 5,737 5,705 Fiduciary services income Income from fiduciary services 1,641 1,535 5,016 4,847 Investment program income Brokerage and insurance commissions 1,217 1,003 3,462 3,269 Other non-interest income Other income 505 509 1,392 1,360 Total non-interest income within the scope of ASC 606 8,533 8,222 24,754 24,552 Total non-interest income not in scope of ASC 606 (3,461) 1,732 294 6,368 Total non-interest income $ 5,072 $ 9,954 $ 25,048 $ 30,920

(2) Represents the assumed dilutive effect of unexercised and/or unvested stock options, restricted shares, restricted share units and contingently issuable performance-based awards utilizing the treasury stock method. (3) Represents stock-based awards not included in the computation of potential common shares for purposes of calculating diluted EPS as the exercise prices were greater than the average market price of the Company's common stock, and, therefore, are considered anti-dilutive. Non-vested stock-based payment awards that contain non-forfeitable rights to dividends are participating securities and are included in the computation of EPS pursuant to the two-class method. The two-class method is an earnings allocation formula that determines EPS for each class of common stock and participating security according to dividends declared (or accumulated) and participation rights in undistributed earnings. Certain of the Company’s non-vested stock-based awards qualify as participating securities.

FAIR VALUE MEASUREMENT AND DISC

FAIR VALUE MEASUREMENT AND DISCLOSURE	9 Months Ended

Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENT AND DISCLOSURE	FAIR VALUE MEASUREMENT AND DISCLOSURE Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value is best determined using quoted market prices. However, in many instances, quoted market prices are not available. In such instances, fair values are determined using various valuation techniques. Various assumptions and observable inputs must be relied upon in applying these techniques. GAAP establishes a fair value hierarchy for valuation inputs that gives the highest priority to quoted prices in active markets for identical assets or liabilities and the lowest priority to unobservable inputs. GAAP permits an entity to choose to measure eligible financial instruments and other items at fair value. The Company has elected the fair value option for its loans held for sale. Electing the fair value option for loans held for sale enables the Company’s financial position to align more clearly with the economic value of the actively traded asset. The fair value hierarchy for valuation of an asset or liability is as follows: Level 1: Valuation is based upon unadjusted quoted prices in active markets for identical assets and liabilities that the entity has the ability to access as of the measurement date. Level 2: Valuation is determined from quoted prices for similar assets or liabilities in active markets, from quoted prices for identical or similar instruments in markets that are not active or by model-based techniques in which all significant inputs are observable in the market. Level 3: Valuation is derived from model-based and other techniques in which at least one significant input is unobservable and which may be based on the Company’s own estimates about the assumptions that market participants would use to value the asset or liability. In general, fair value is based upon quoted market prices, where available. If such quoted market prices are not available, fair value is based upon model-based techniques incorporating various assumptions including interest rates, prepayment speeds and credit losses. Assets and liabilities valued using model-based techniques are classified as either Level 2 or Level 3, depending on the lowest level classification of an input that is considered significant to the overall valuation. A description of the valuation methodologies used for instruments measured at fair value, as well as the general classification of such instruments pursuant to the valuation hierarchy, is set forth below. Financial Instruments Recorded at Fair Value on a Recurring Basis Trading Securities and Deferred Compensation: The fair value of trading securities and deferred compensation is reported using market quoted prices and has been classified as Level 1 as such securities and underlying securities are actively traded and no valuation adjustments have been applied. Debt Securities : The fair value of investments in debt securities is reported utilizing prices provided by an independent pricing service based on recent trading activity and other observable information including, but not limited to, dealer quotes, market spreads, cash flows, market interest rate curves, market consensus prepayment speeds, credit information, and the bond’s terms and conditions. The fair value of debt securities is classified as Level 2. Loans Held For Sale: The fair value of loans held for sale is determined on an individual loan basis using quoted secondary market prices and is classified as Level 2. Derivatives : The fair value of interest rate swaps is determined using inputs that are observable in the market place obtained from third parties including yield curves, publicly available volatilities, and floating indexes and, accordingly, are classified as Level 2 inputs. The credit value adjustments associated with derivatives utilize Level 3 inputs, such as estimates of current credit spreads to evaluate the likelihood of default. As of September 30, 2023 and December 31, 2022, the credit valuation adjustment on the overall valuation of its derivative positions and was not significant to the overall valuation of its derivatives, and, thus, the Company's interest rate swaps were classified as Level 2. The fair value of the Company's fixed rate interest rate lock commitments were determined using secondary market pricing for loans with similar structures, including term, rate and borrower credit quality, adjusted for the Company's pull-through rate estimate (i.e. estimate of loans within its loan pipeline that will ultimately complete the origination process and be funded). The Company has classified its fixed rate interest rate lock commitments as Level 2, as the quoted secondary market prices are the more significant input, and, although the Company's internal pull-through rate estimate is a Level 3 estimate, it is less significant to the ultimate valuation. The fair value of the Company's forward delivery commitments is determined using secondary market pricing for loans with similar structures, including term, rate and borrower credit quality, and the locked and agreed to price with the secondary market investor. The Company has classified its fixed rate interest rate lock commitments as Level 2. The following table summarizes financial assets and financial liabilities measured at fair value on a recurring basis, segregated by the level of the valuation inputs within the fair value hierarchy utilized to measure fair value, for the dates indicated: (In thousands) Fair Readily Observable Company September 30, 2023 Financial assets: Trading securities $ 4,195 $ 4,195 $ — $ — AFS debt securities: Obligations of states and political subdivisions 40,669 — 40,669 — MBS issued or guaranteed by U.S. government-sponsored enterprises 424,976 — 424,976 — CMO issued or guaranteed by U.S. government-sponsored enterprises 104,816 — 104,816 — Corporate bonds 18,542 — 18,542 — Loans held for sale 11,187 — 11,187 — Customer loan swaps 19,785 — 19,785 — Interest rate contracts 23,853 — 23,853 — Fixed rate mortgage interest rate lock commitments 26 — 26 — Forward delivery commitments 198 — 198 — Financial liabilities: Deferred compensation $ 4,195 $ 4,195 $ — $ — Customer loan swaps 19,834 — 19,834 — Interest rate contracts 2,817 — 2,817 — Fixed rate mortgage interest rate lock commitments 154 — 154 — Forward delivery commitments 2 — 2 — December 31, 2022 Financial assets: Trading securities $ 3,990 $ 3,990 $ — $ — AFS debt securities: Obligations of states and political subdivisions 49,226 — 49,226 — MBS issued or guaranteed by U.S. government-sponsored enterprises 514,019 — 514,019 — CMO issued or guaranteed by U.S. government-sponsored enterprises 109,347 — 109,347 — Corporate bonds 23,283 — 23,283 — Loans held for sale 5,197 — 5,197 — Customer loan swaps 14,802 — 14,802 — Interest rate contracts 13,051 — 13,051 — Fixed rate mortgage interest rate lock commitments 31 — 31 — Forward delivery commitments 114 — 114 — Financial liabilities: Deferred compensation $ 3,990 $ 3,990 $ — $ — Customer loan swaps 14,850 — 14,850 — Interest rate contracts 5,515 — 5,515 — Fixed rate mortgage interest rate lock commitments 87 — 87 — The Company did not have any transfers between Level 1 and Level 2 of the fair value hierarchy during the nine months ended September 30, 2023. The Company’s policy for determining transfers between levels occurs at the end of the reporting period when circumstances in the underlying valuation criteria change and result in transfer between levels. Financial Instruments Recorded at Fair Value on a Nonrecurring Basis The Company may be required, from time to time, to measure certain financial assets and financial liabilities at fair value on a nonrecurring basis in accordance with GAAP, which may consist of collateral-dependent loans and servicing assets. These include assets that are measured at the lower of cost or market value that were recognized at fair value below cost at the end of the period. As of September 30, 2023 and December 31, 2022, the Company did not have any material financial instruments measured and reported at fair value. Collateral-Dependent Loans : Expected credit losses on individually assessed loans deemed to be collateral dependent are valued based upon the lower of amortized cost or fair value of the underlying collateral less costs to sell. Management estimates the fair values of these assets using Level 2 inputs, such as the fair value of collateral based on independent third-party market approach appraisals for collateral-dependent loans, and Level 3 inputs where circumstances warrant an adjustment to the appraised value based on the age of the appraisal and/or comparable sales, condition of the collateral, and market conditions. Servicing Assets : The Company accounts for mortgage servicing assets at cost, subject to impairment testing. When the carrying value of a tranche exceeds fair value, a valuation allowance is established to reduce the carrying cost to fair value. Fair value is based on a valuation model that calculates the present value of estimated net servicing income. The Company obtains a third-party valuation based upon loan level data including note rate, type and term of the underlying loans. The model utilizes two significant unobservable inputs, namely loan prepayment assumptions and the discount rate used, to calculate the fair value of each tranche, and, as such, the Company has classified the model within Level 3 of the fair value hierarchy. Non-Financial Instruments Recorded at Fair Value on a Non-Recurring Basis The Company had no non-financial assets or non-financial liabilities measured at fair value on a non-recurring basis as of September 30, 2023 and December 31, 2022. Non-financial assets measured at fair value on a non-recurring basis consist of OREO, goodwill and core deposit intangible assets. OREO : OREO properties acquired through foreclosure or deed in lieu of foreclosure are recorded at net realizable value, which is the fair value of the real estate, less estimated costs to sell. Any write-down of the recorded investment in the related loan is charged to the ACL upon transfer to OREO. Upon acquisition of a property, a current appraisal is used or an internal valuation is prepared to substantiate fair value of the property. After foreclosure, management periodically, but at least annually, obtains updated valuations of the OREO properties and, if additional impairments are deemed necessary, the subsequent write-downs for declines in value are recorded through a valuation allowance and a provision for credit losses charged to other non-interest expense within the consolidated statements of income. As management considers appropriate, adjustments are made to the appraisal obtained for the OREO property to account for recent sales activity of comparable properties, changes in the condition of the property, and changes in market conditions. These adjustments are not observable in an active market and are classified as Level 3. At September 30, 2023 and December 31, 2022, the Company did not have any OREO properties. Goodwill : Goodwill represents the excess cost of an acquisition over the fair value of the net assets acquired. The fair value of goodwill is estimated by utilizing several standard valuation techniques, including discounted cash flow analyses, bank merger multiples, and/or an estimation of the impact of business conditions and investor activities on the long-term value of the goodwill. Should an impairment occur, the associated goodwill is written-down to fair value and the impairment charge is recorded within non-interest expense in the consolidated statements of income. The Company conducts an annual impairment test of goodwill in the fourth quarter each year, or more frequently as necessary. There have been no indications or triggering events during the nine months ended September 30, 2023, for which management believes it is more likely than not that goodwill is impaired. Core Deposit Intangible Assets : The Company's core deposit intangible assets represent the estimated value of acquired customer relationships and are amortized over the estimated life of those relationships. Core deposit intangibles are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. There were no events or changes in circumstances for the nine months ended September 30, 2023, that indicated the carrying amount may not be recoverable. The estimated fair values and related carrying amounts for assets and liabilities for which fair value is only disclosed are shown below as of the dates indicated: Carrying Fair Value Readily Observable Company September 30, 2023 Financial assets: HTM debt securities $ 549,961 $ 483,547 $ — $ 483,547 $ — Commercial real estate loans (1)(2) 1,634,347 1,532,605 — — 1,532,605 Commercial loans (2) 395,549 379,502 — — 379,502 Residential real estate loans (2) 1,742,359 1,460,556 — — 1,460,556 Home equity loans (2) 231,155 228,878 — — 228,878 Consumer loans (2) 18,596 16,385 — — 16,385 Servicing assets 2,316 4,321 — — 4,321 Financial liabilities: Time deposits $ 617,609 $ 609,195 $ — $ 609,195 $ — Short-term borrowings 470,140 469,103 — 469,103 — Junior subordinated debentures 44,331 31,475 — 31,475 — December 31, 2022 Financial assets: HTM debt securities $ 546,583 $ 506,193 $ — $ 506,193 $ — Commercial real estate loans (1)(2) 1,605,279 1,550,379 — — 1,550,379 Commercial loans (2) 424,685 414,353 — — 414,353 Residential real estate loans (2) 1,691,177 1,494,707 — — 1,494,707 Home equity loans (2) 232,203 237,967 — — 237,967 Consumer loans (2) 20,087 17,853 — — 17,853 Servicing assets 2,458 4,412 — — 4,412 Financial liabilities: Time deposits $ 300,451 $ 291,568 $ — $ 291,568 $ — Short-term borrowings 265,176 264,779 — 264,779 — Junior subordinated debentures 44,331 31,032 — 31,032 — (1) Commercial real estate loan includes non-owner-occupied and owner-occupied properties.

RECENT ACCOUNTING PRONOUNCEME_2

RECENT ACCOUNTING PRONOUNCEMENTS (Policies)	9 Months Ended

Accounting Standards Update and Change in Accounting Principle [Abstract]
Accounting Standards Adopted	The Company adopted and updated its accounting policies for the following accounting standards that have been applied to the Company's interim consolidated financial statements for the three and nine months ended September 30, 2023: ASU No. 2022-01, Derivatives and Hedging ( Topic 815): Fair Value Hedging - Portfolio Layer Method ("ASU 2022-01"). The FASB issued ASU 2022-01 to amend ASU 2017-12, which was adopted by the Company in 2018. This amendment renames the "last-of-layer" method to the "portfolio layer" method, permits non-repayable financial assets to be included in a closed portfolio hedged using the portfolio layer method, and provides additional guidance for entities that apply the portfolio layer method of hedge accounting in accordance with Topic 815. The Company adopted ASU 2022-01, as amended, effective January 1, 2023 and leveraged the "portfolio layer" method to enter into interest rate swaps to hedge fixed-rate residential mortgages during the nine months ended September 30, 2023. There was no impact to the Company's consolidated financial statements upon adoption. Refer to Note 8 of the consolidated financial statements for further details. ASU No. 2022-02, Financial Instruments - Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures ("ASU 2022-02"). The FASB issued ASU 2022-02 to provide new guidance on TDRs and charge-offs for entities that have adopted ASU 2016-13. The Company adopted ASU 2022-02 effective January 1, 2023 on a prospective basis, and upon adoption there was no impact to the consolidated financial statements. The adoption of ASU 2022-02 eliminates the accounting and disclosure requirements for TDRs, including the requirement to measure the allowance using a discounted cash flow ("DCF") methodology. Beginning January 1, 2023, the Company no longer establishes a specific reserve for newly modified loans to borrowers experiencing financial difficulty. Instead, these modifications are included in their respective segments, and the ACL is calculated utilizing models that consider the borrowers' probability of default, loss given default and exposure at default. ASU 2022-02 also requires disclosure of modifications of loans to borrowers experiencing financial difficulty if the modification involves principal forgiveness, an interest rate reduction, an other-than-insignificant payment delay, a term extension, or a combination of any of these types of modifications. Additionally, ASU 2022-02 requires the disclosure of current period gross charge-offs by year of loss origination (vintage) which are required to be applied prospectively as of January 1, 2023, the Company's date of adoption. Refer to Note 4 of the consolidated financial statements for further details. The following provides a brief description of recently issued accounting pronouncements that have yet to be adopted by the Company: ASU No. 2023-02, Investments - Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method ("ASU 2023-02"). The FASB issued ASU 2023-02 to permit reporting entities to elect to account for tax equity investments, regardless of the tax credit program from which the income tax credits are received, using the proportional amortization method if certain conditions are met. Under the proportional amortization method, the initial cost of the investment is amortized in proportion to the income tax credits or other tax benefits received. ASU 2023-02 is effective for interim and annual periods beginning after December 15, 2023. Although the Company continues to evaluate the potential effects of ASU 2023-02, it does not expect the adoption of ASU 2023-02 to have a material impact on its consolidated financial statements.
