Camden National Corporation, a Maine corporation (the “Company”), is the bank holding company for Camden National Bank (the “Bank”) and is headquartered in Camden, Maine. The primary business of the Company is to attract deposits from and to extend loans to consumer, institutional, municipal, non-profit and commercial customers. The Company, through the Bank, offers commercial and consumer banking products and services, and through Camden Financial Consultants, a division of the Bank, and Camden National Wealth Management, a department of the Bank, offers brokerage and insurance services as well as investment management and fiduciary services. The Bank's deposits are insured by the FDIC, subject to regulatory limits. Principles of Consolidation . The accompanying consolidated financial statements include the accounts of the Company and the Bank (which includes the consolidated accounts of 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, 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 CCTA and UBCT. These entities are unconsolidated subsidiaries of the Company. Reclassifications . Certain reclassifications have been made to prior year amounts, without impact to net income or total shareholders' equity, to conform to the current year's presentation. Use of Estimates . The preparation of the financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could vary from these estimates as a result of changing conditions and future events. Several estimates are particularly critical and are susceptible to significant near-term change, such as the ACL, including the allowance for loan losses, off-balance sheet credit exposures, and AFS and HTM debt securities; the accounting for business combinations including subsequent impairment analyses for goodwill and other intangible assets; accounting for income taxes; and postretirement benefits. Subsequent Events . The Company has evaluated events and transactions subsequent to December 31, 2022 for potential recognition or disclosure as required by GAAP and have been disclosed in Note 12. Significant Concentration of Credit Risk. The Company makes loans primarily to customers in Maine, Massachusetts and New Hampshire. Although it has a diversified loan portfolio, a large portion of the Company's loans are secured by commercial or residential real estate and are subject to real estate market volatility within these states. Furthermore, the debtors' ability to honor their contracts is highly dependent upon other economic factors throughout Maine, Massachusetts and New Hampshire. The Company does not generally engage in non-recourse lending and typically will require the principals of any commercial borrower to obligate themselves personally on the loan. Refer to Note 3 for further discussion of credit concentrations. Cash, Cash Equivalents and Restricted Cash . For the purpose of reporting, cash and cash equivalents consist of cash on hand and amounts due from banks. In March 2020, the FRB reduced its reserve requirement ratios to 0%, effectively eliminating cash reserve requirements for all depository institutions. Certain cash balances will be designated as restricted as required by certain contracts with unrelated third parties. Investments. Debt investments for which the Company has the positive intent and ability to hold to maturity are classified as HTM and recorded at amortized cost on the consolidated statements of condition. Debt investments that are not classified as HTM or trading are classified as AFS and are carried at fair value on the Company's consolidated statements of condition with subsequent changes to fair value recorded within AOCI, net of tax. Trading securities and equity investments with a readily determinable fair value are carried at fair value on the Company's consolidated statements of condition, with the change in fair value recognized between periods recognized within net income on the consolidated statements of income. Purchase premiums and discounts are recognized in interest income on the consolidated statements of income using the interest method over the period to maturity or issuer call option date, if earlier, and are recorded on the trade date. Upon sale of an investment security, the realized gain or loss on the sale is recognized within non-interest income on the consolidated statements of income. The cost basis of our investments sold is determined using the specific identification method. ACL on (or Write-off of) AFS Debt Securities. Management assesses its AFS debt securities in an unrealized loss position for the following: (i) whether it intends to sell the security, or (ii) it is more likely than not that it will be required to sell the security before recovery of its amortized cost basis. If either of the criteria regarding intent or requirement to sell is met, the security’s amortized cost basis is written down to fair value through net income. For AFS debt securities that do not meet either of the two criteria, management evaluates whether the decline in fair value resulted from credit losses or other factors. In making this assessment, management considers the following: (i) the extent to which fair value is less than amortized cost, (ii) credit rating of the security, (iii) macroeconomic trends of the industry specific to the security, and (iv) any other adverse conditions specifically related to the security, among other factors. If this assessment indicates that a credit loss exists, the present value of cash flows expected to be collected from the security are compared to the amortized cost basis of the security. If the present value of cash flows expected to be collected is less than the amortized cost basis, a credit loss exists and an allowance on AFS debt securities is recorded for the credit loss, limited by the amount that the fair value is less than the amortized cost basis. When assessing an AFS debt security for credit loss, securities with identical CUSIPs are pooled together to assess for impairment using the average cost basis. Any impairment that has not been recorded through an allowance is recognized in AOCI. A change in the ACL on AFS debt securities or write-off of an AFS debt security, which may be in full or a portion thereof, is recorded as expense (credit) within provision for credit losses on the consolidated statements of income. Losses are charged against the allowance when management believes the uncollectibility of an AFS debt security is confirmed or when either of the criteria regarding intent or requirement to sell is met. As of December 31, 2022 and 2021, there was no allowance carried on the Company's AFS debt securities nor were there any permanent write-offs for the years ended December 31, 2022, 2021, or 2020. Refer to Note 2 of the consolidated financial statements for further discussion. ACL on (or Write-off of) HTM Debt Securities. The Company estimates expected credit losses on its HTM debt securities and carry an allowance for such. Management measures expected credit losses on HTM debt securities on a collective basis by major security types that share similar risk characteristics, which may include, but is not limited to, credit ratings, financial asset type, collateral type, size, effective interest rate, term, geographical location, industry, and vintage. The estimate of expected credit losses on the HTM portfolio is based on the expected cash flows of each individual CUSIP over its contractual life and considers historical credit loss information, current conditions and reasonable and supportable forecasts. Under ASU 2016-13 the Company has the ability to exclude certain securities when the historical credit loss information, adjusted for current conditions and forecasts, resulting in zero risk of nonpayment of the amortized cost basis of the security. The Company has evaluated and determined zero risk of nonpayment on all securities guaranteed by the U.S government agencies. Given the rarity of municipal and corporate bond defaults and losses, the Company will utilize external third party loss forecast models as the sole source of municipal and corporate bond default and loss rates. As with the loan portfolio, cash flows are modeled over a reasonable and supportable forecast period and then revert to the long-term average economic conditions on a straight line basis. Management may exercise discretion to make adjustments based on various qualitative factors. An HTM debt security is written-off in the period in which a determination is made that all or a portion of the financial asset is uncollectible. Any previously recorded allowance, if any, is reversed and then the amortized cost basis is written-down to the amount deemed to be collectible, if any. A change in the ACL on HTM debt securities or write-off of an HTM debt security, which may be in full or a portion thereof, is recorded as expense (credit) within provision for credit losses on the consolidated statements of income. As of December 31, 2022 and 2021, there was no allowance carried on the Company’s HTM debt securities nor were there any permanent write-offs for the years ended December 31, 2022, 2021, or 2020. Refer to Note 2 of the consolidated financial statements for further discussion. FHLBB and FRBB Stock. The Company, through the Bank, is a member of the FHLBB and FRBB, and, as a member, is required to hold a certain amount of FHLBB and FRB common stock. These equity stocks are non-marketable and are reported at cost within other investments on the consolidated statements of condition. The Company evaluates its FHLBB and FRB common stock for impairment based on the ultimate recoverability of the par value rather than by recognizing temporary declines in value. Loans Held for Sale. The Company has elected the fair value option for loans classified as held for sale on the consolidated statements of condition. Designation of loans as held for sale is determined based on intent and is generally completed as the loans are underwritten. The fair value for loans held for sale is determined using quoted secondary market prices. Management consistently evaluates the Company's loan portfolio in conjunction with asset/liability management practices, and will opt to sell certain residential mortgage loans to manage the Company's interest rate exposure and for other business purposes, including generating fee income through mortgage sale gains and managing its liquidity position. Loans Held for Investment and Acquired Loans . Loans held for investment are reported at amortized cost, adjusted for any partial charge-offs and net of any deferred loan fees or costs. Interest income is accrued based upon the daily principal amount outstanding, except for loans on non-accrual status. Loan fees and certain direct origination costs are deferred and amortized into interest income over the contractual term of the loan using the level-yield method. When a loan is paid off, the unamortized portion is recognized in interest income. Loans acquired through a business or asset purchase are reported at fair value, as of acquisition date. Interest income is accrued based upon the daily principal amount outstanding and is then further adjusted by the accretion of any discount or amortization of any premium associated with the loan that was recognized based on the acquisition date fair value using the level-yield method. When a loan is paid off, the unamortized portion is recognized in interest income. A loan is classified as non-accrual generally when it becomes 90 days past due as to interest or principal payments, or sooner if management considers such action to be prudent. All previously accrued but unpaid interest on non-accrual loans is reversed from interest income in the period in which the loan is considered delinquent and the amortization of any unamortized net deferred origination loan fees/costs stops. Interest payments received on non-accrual loans are applied as a reduction of principal. A loan remains on non-accrual status until all principal and interest amounts contractually due are brought current and future payments are reasonably assured. Should a loan transition from non-accrual to accrual, the unrecognized interest earned during the period the loan was on non-accrual and unamortized deferred origination fees and costs are recognized over the remaining contractual life of the loan using the level-yield method. ACL on Loans. Upon adoption of ASU 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”), as amended; effective January 1, 2020, using a modified-prospective approach. Upon adoption, the Company recorded a cumulative-effect adjustment of $2.8 million reducing retained earnings, with a corresponding adjustment of $233,000 increasing the ACL on loans, an adjustment of $3.3 million increasing other liabilities for the ACL on off-balance sheet credit exposures, and an adjustment of $769,000 increasing deferred tax assets. The ACL on loans is based on the amortized cost basis of a loan, which is comprised of the unpaid principal balance of the loan, net deferred loan fees (costs), acquired premium (discount), and any write-downs previously taken on the loan. The ACL on loans is increased by charges to provision for credit losses and reduced by charge-offs, net of recoveries. Management evaluates the appropriateness of the ACL on loans quarterly. This evaluation is inherently subjective as it requires material estimates that may be susceptible to significant change from period to period. The ACL on loans is presented on the consolidated statements of condition. Loans past due 30 days or more are considered delinquent. In general, secured loans that are delinquent for 90 consecutive days are placed on non-accrual status and may be subject to individual loss assessment in accordance with established internal policy. In general, unsecured loans that are delinquent for 90 consecutive days are charged-off. In cases where a borrower experiences financial difficulties and the Company makes certain concessionary modifications to contractual terms, the loan is classified as a TDR, with the exception of loan modifications or concessions resulting directly from the effects of the COVID-19 pandemic during 2020 and 2021 that were granted to customers who were otherwise in current payment status at the time of the modification or concession. The ACL on loans reduces the loan portfolio to the net amount expected to be collected, and represents the expected losses over the life of all loans at the reporting date. The allowance incorporates forward-looking information and applies a reversion methodology beyond the reasonable and supportable forecast. The ACL on loans represents the Company's estimated risk of loss within its loan portfolio as of the reporting date. To appropriately measure expected credit losses, management disaggregates the loan portfolio into pools of similar risk characteristics ( i.e. “segments”). The Company utilizes a discounted cash flow approach to calculate the expected loss for each segment. Within the discounted cash flow model, a PD and LGD assumption is applied to calculate the expected loss for each segment. PD is the probability the asset will default within a given timeframe and LGD is the percentage of assets not expected to be collected due to default. The Company's PD and LGD assumptions may be derived from internal historical default and loss experience or from external data where there are not statistically meaningful loss events for a loan segment or it does not have default and loss data that covers a full economic cycle. As of December 31, 2022 and 2021, the primary macroeconomic drivers used within the discounted cash flow model included forecasts of Maine Unemployment, changes in Maine and National GDP, and changes in the Maine Housing Price Index. Management monitors and assesses its macroeconomic drivers at least annually (generally in the fourth quarter) to determine if or that they continue to be the most predictive indicator of losses within the Company’s loan portfolio, and these macroeconomic drivers may change from time to time. To determine its reasonable and supportable forecast, management may leverage macroeconomic forecasts obtained from various reputable sources, which may include, but is not limited to, the Federal Open Market Committee forecast and other publicly available forecasts from well recognized, leading economists or firms. The Company’s reasonable and supportable forecast period generally ranges from one to three years, depending on the facts and circumstances of the current state of the economy, portfolio segment and management’s judgement of what can be reasonably supported. The model reversion period generally ranges from one to six years, and it also depends on the current state of the economy and management’s judgments of such. Management monitors and assesses the forecast and reversion period at least annually. The Company used a one-year forecast and reversion period to calculate the ACL on loans as of December 31, 2022 and 2021. The ACL on loans is calculated over a loan’s contractual life. For term loans, the contractual life is calculated based on the maturity date. For commercial revolving loans with no stated maturity date, the contractual life is calculated based on the internal review date. For all other revolving loans, the contractual life is based on either the estimated maturity date or a default date. The contractual term does not include expected extension, renewals or modifications. The Company's loan portfolio is segmented as follows based on the various risk profiles of the Company's loans: • The commercial loan portfolio is segmented into three categories – (i) commercial real estate, which is collateralized by real estate; (ii) commercial, which is typically utilized for general business purposes; and (iii) SBA PPP loans, which were originated by the Company during the years ended December 31, 2021 and 2020 in response to the COVID-19 pandemic. Commercial real estate is further segmented between non-owner-occupied ( i.e . investment properties) and owner-occupied properties. • Retail loans are a homogenous group, generally consisting of standardized products that are smaller in amount and distributed over a large number of individual borrowers. Retail loans are segmented into three categories – (i) residential real estate, (ii) home equity and (iii) consumer. In calculating the ACL on loans, the contractual life of a loan must be adjusted for prepayments to arrive at expected cash flows. The Company models term loans using an annualized prepayment. When the Company has a specific expectation of differing payment behavior for a given loan, the loan may be evaluated individually. For revolving loans that do not have a principal payment schedule, a curtailment rate is factored into the cash flow. The ACL on loans evaluation may also consider various qualitative factors, such as: (i) actual or expected changes in economic trends and conditions, (ii) changes in the value of underlying collateral for loans, (iii) changes to lending policies, underwriting standards and/or management personnel performing such functions, (iv) delinquency and other credit quality trends, (v) credit risk concentrations, if any, (vi) changes to the nature of the Company's business impacting the loan portfolio, (vii) and other external factors, that may include, but are not limited to, results of internal loan reviews, examinations by bank regulatory agencies, or other such events such as a natural disaster. Certain loans are individually evaluated for estimated credit losses, including those (i) greater than $500,000 that are classified as substandard or doubtful and are on non-accrual, (ii) a TDR, or (iii) that have other unique characteristics differing from the segment. Specific reserves are established when appropriate for such loans based on the present value of expected future cash flows of the loan or the estimated realizable value of the collateral, if any. Management may also adjust its assumptions to account for differences between expected and actual losses from period-to-period. The variability of management’s assumptions could alter the ACL on loans materially and impact future results of operations and financial condition. The loss estimation models and methods used to determine the allowance for credit losses are continually refined and enhanced. Accrued Interest. Accrued interest receivable balances are presented within other assets on the consolidated statements of condition, and excluded from the measurement of the ACL, including investments and loans. Accrued interest receivable is written-off by reversing previously recognized interest income. The Company has a robust policy in place to write-off accrued interest when a loan is placed on non-accrual. For loans, write-off typically occurs when a loan has been in default for 90 days or more. Goodwill and Core Deposit Intangible Assets . Goodwill represents the price paid in an acquisition that is in excess of the fair value of the net assets acquired. Goodwill is not subject to amortization but rather is evaluated at least annually for impairment, or as events and circumstances dictate, at the reporting unit level, and for which the Company has determined it has a single reporting unit. Any impairment is charged to non-interest expense on the consolidated statements of income. The Company evaluates goodwill for impairment annually as of November 30 th , or more frequently as warranted by external and/or internal factors. The Company may utilize a qualitative analysis and/or a quantitative analysis to evaluate goodwill for impairment. The Company has the option to by-pass the qualitative analysis for any given year and perform the quantitative analysis. Using a qualitative analysis to assess goodwill for impairment, the Company will consider various factors to determine if it is more-likely-than-not that its carrying value of its reporting unit exceeds its fair value. These factors include, but are not limited to, the overall macro-economic environment; industry economic and regulatory environment; and company specific factors, including, but not limited to, performance, Company common stock share price, competition and/or significant changes in senior management. Should the Company determine it is more-likely-than-not that the carrying value of its reporting unit exceeds its fair value, then it would then perform the next step of the goodwill impairment test, which is a quantitative analysis. If the Company were to determine it is not more-likely-than-not that the carrying value of its reporting unit exceeds its fair value, the Company would have completed its goodwill impairment evaluation and concluded goodwill was not impaired. After performing the qualitative analysis and determining it is more-likely-than-not that the carrying value of its reporting unit exceeds its fair value or if the Company by-passed the qualitative analysis, it would perform a quantitative analysis to determine if the carrying value of its reporting unit exceeds its fair value. Alternatively, the Company may bypass the qualitative analysis and use a quantitative analysis. In completing the quantitative analysis, the Company may use various valuation techniques such as a discounted cash flow model, a comparative market transaction multiple approach and/or other valuation methods to determine the reporting unit's fair value. Goodwill impairment is recognized the extent the carrying value of a reporting unit exceeds its fair value. The Company completed its testing for impairment of goodwill for the years ended December 31, 2022, 2021 and 2020 and concluded goodwill was not impaired. Refer to Note 4 of the consolidated financial statements for further details. Core deposit intangible assets represents the estimated value of acquired customer relationships and is amortized on a straight-line basis 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. If necessary, management will test the core deposit intangibles for impairment by comparing their carrying value to the expected undiscounted cash flows of the assets. If the undiscounted cash flows of the intangible assets exceed their carrying value then the intangible assets are deemed to be fully recoverable and not impaired. However, if the undiscounted cash flows of the intangible assets are less than their carrying value then management must compare the fair value of the intangible assets to its carrying value. If the fair value of the intangible assets exceeds their carrying value then the intangible assets are not impaired. If the fair value of the intangible assets is less than its carrying value, then an impairment charge is recorded to mark the carrying value of the intangible assets to fair value. For the years ended December 31, 2022, 2021 and 2020, there were no events or changes in circumstances that indicated the carrying amount may not be recoverable. BOLI . BOLI represents the cash surrender value of life insurance policies on the lives of certain active and retired employees where the Company is the beneficiary and is recorded as an asset on the consolidated statements of condition. Increases in the cash surrender values of the policies, as well as death benefits received, net of any cash surrender value, are recorded in non-interest income on the consolidated statements of income, and are not subject to income taxes. The Company reviews the financial strength of the insurance carriers prior to the purchase of life insurance policies and no less than annually thereafter. A life insurance policy with any individual carrier is limited to 10% of Tier 1 capital (as defined for regulatory purposes) and the total cash surrender value of life insurance policies is limited to 25% of Tier 1 capital. Premises and Equipment . Premises and equipment purchased in normal course are stated at cost less accumulated depreciation, while premises and equipment obtained through the acquisition of a company or branch acquisition are stated at their estimated fair values as of the acquisition date less accumulated depreciation that occurred subsequent to the acquisition date. Depreciation and amortization are computed using the straight-line method over the estimated useful lives of the related assets. Leasehold improvements are amortized over the lesser of the term of the respective lease or the estimated life of the improvement. Land is carried at cost. Repairs and maintenance costs that are not an improvement or do not extend the estimated useful life of the asset are expensed as incurred. Software costs, including cloud-based software licenses that qualify as internal-use software, are stated at cost less accumulated amortization within other assets on the consolidated statements of condition. Amortization expense is calculated using the straight-line method over the estimated useful lives of the related assets. Cloud-based software costs that do not qualify as internal-use software are capitalized as service contracts within other assets on the consolidated statements of condition and expensed ratably over the term of the contract period. Long-lived assets, including premises and equipment and certain identifiable intangibles, are reviewed for impairment whenever events or changes in circumstances indicate the carrying amount of an asset may not be recoverable. The amount of the impairment loss, if any, is based on the asset’s fair value. No impairment losses were recognized in 2022, 2021, or 2020. Leases. The Company leases office space, space for ATM locations and certain branch locations under noncancellable operating leases, several of which have renewal options to extend lease terms. Upon commencement of a new lease, the Company will recognize a ROU asset and corresponding lease liability. The Company makes the decision on whether to renew an option to extend a lease by considering various factors. The Company will recognize an adjustment to ROU asset and lease liability when lease agreements are amended and executed. The discount rate used in determining the present value of lease payments is based on the lessor’s implicit rate in the lease if known or on the Company's incremental borrowing rate for borrowing terms similar to each lease at commencement date. The Company has lease agreements with lease and non-lease components, which are generally accounted for separately. For real estate leases, non-lease components and other non-components, such as common area maintenance charges, real estate taxes and insurance, are not included in the measurement of the lease liability since they are generally able to be segregated. The Company has elected the short-term lease recognition exemption for all leases that qualify. OREO . OREO properties acquired through foreclosure or deed-in-lieu of foreclosure are recorded initially at estimated fair value less estimated costs to sell. Any write-down of the recorded investment in the related loan is charged to the ACL on loans 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. Any subsequent declines in the fair value of a property are recorded as a valuation all

Investments, Debt and Equity Securities [Abstract]
Investments	INVESTMENTS Trading Securities Trading securities are reported on the Company's consolidated statements of condition at fair value. As of December 31, 2022 and 2021, the fair value of the Company's trading securities were $4.0 million and $4.4 million, respectively. 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 December 31, 2022 Obligations of states and political subdivisions $ 49,678 $ 11 $ (463) $ 49,226 Mortgage-backed securities issued or guaranteed by U.S. government-sponsored enterprises 598,845 131 (84,957) 514,019 Collateralized mortgage obligations issued or guaranteed by U.S. government-sponsored enterprises 122,760 — (13,413) 109,347 Subordinated corporate bonds 25,677 3 (2,397) 23,283 Total AFS debt securities $ 796,960 $ 145 $ (101,230) $ 695,875 December 31, 2021 Obligations of U.S. government-sponsored enterprises $ 8,585 $ — $ (241) $ 8,344 Obligations of states and political subdivisions 112,086 5,392 — 117,478 Mortgage-backed securities issued or guaranteed by U.S. government-sponsored enterprises 1,003,869 7,856 (11,468) 1,000,257 Collateralized mortgage obligations issued or guaranteed by U.S. government-sponsored enterprises 361,781 2,835 (5,767) 358,849 Subordinated corporate bonds 22,660 152 (254) 22,558 Total AFS debt securities $ 1,508,981 $ 16,235 $ (17,730) $ 1,507,486 As of December 31, 2022 and 2021, 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 the 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 interest income on the consolidated statements of income. At December 31, 2022, the net unrealized losses on the transferred securities reported within AOCI were $52.2 million, net of a deferred tax asset of $14.3 million. At December 31, 2022, net unrealized losses on AFS debt securities reported within AOCI (excluding the aforementioned securities transferred from AFS to HTM) were $79.4 million, net of a deferred tax asset of $21.7 million. At December 31, 2021, net unrealized losses on AFS debt securities were $1.2 million, net of a deferred tax asset of $321,000. The following table details the Company’s sales of AFS debt securities for the periods indicated below: For the Year Ended (In thousands) 2022 2021 2020 Proceeds from sales of AFS debt securities $ 36,280 $ — $ — Gross realized gains 13 — — Gross realized losses (925) — — The following table presents 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 Holdings Fair Value Unrealized Losses Fair Value Unrealized Losses Fair Value Unrealized Losses December 31, 2022 Obligations of states and political subdivisions 83 $ 42,276 $ (463) $ — $ — $ 42,276 $ (463) Mortgage-backed securities issued or guaranteed by U.S. government-sponsored enterprises 175 118,290 (11,521) 381,355 (73,436) 499,645 (84,957) Collateralized mortgage obligations issued or guaranteed by U.S. government-sponsored enterprises 64 47,340 (4,589) 62,007 (8,824) 109,347 (13,413) Subordinated 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) December 31, 2021 Obligations of U.S. government-sponsored enterprises 4 $ 8,344 $ (241) $ — $ — $ 8,344 $ (241) Mortgage-backed securities issued or guaranteed by U.S. government-sponsored enterprises 113 659,851 (8,999) 61,978 (2,469) 721,829 (11,468) Collateralized mortgage obligations issued or guaranteed by U.S. government-sponsored enterprises 56 191,456 (4,602) 38,117 (1,165) 229,573 (5,767) Subordinated corporate bonds 7 11,932 (232) 979 (22) 12,911 (254) Total AFS debt securities 180 $ 871,583 $ (14,074) $ 101,074 $ (3,656) $ 972,657 $ (17,730) As of December 31, 2022 and 2021, the unrealized losses on 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, were not reflective of credit events and the issuers continue to make timely principal and interest payments on the bonds. Agency-backed and government-sponsored enterprise securities have a long 40-year 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. Subordinate corporate bonds are primarily comprised of investment grade senior notes and senior subordinated notes on other financial institutions. At December 31, 2022 and 2021, total accrued interest receivable on AFS debt securities, which has been excluded from reported amortized cost basis on AFS debt securities, was $1.9 million and $3.4 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. At December 31, 2022, the amortized cost and estimated fair values of the Company’s AFS debt securities by contractual maturity 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. Mortgage-related securities are shown in total, as their maturities are highly variable.

In June of 2022, the Company transferred securities with a fair value of $520.3 million from AFS to HTM. See earlier discussion within “AFS Debt Securities” for further details. 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. Subordinate corporate bonds are primarily comprised of investment grade senior notes and senior subordinated notes on other financial institutions. Accordingly, the Company determined that the expected credit loss on its HTM portfolio was immaterial, and therefore, an allowance was not carried on its HTM debt securities at December 31, 2022 or 2021. As of December 31, 2022 and 2021, none of the Company's HTM debt securities were past due or on non-accrual status. The Company did not recognize any interest income on non-accrual HTM debt securities during the years ended December 31, 2022, 2021, and 2020. At December 31, 2022 and 2021, total accrued interest receivable on HTM debt securities, which has been excluded from reported amortized cost basis on HTM debt securities, was $1.7 million and $10,000, 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. At December 31, 2022, the amortized cost and estimated fair values of HTM debt securities by contractual maturity 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.

The Company's lending activities are primarily conducted in Maine, but also include loan production offices in Massachusetts and New Hampshire. The Company originates single- and multi-family residential loans, commercial real estate loans, business loans, municipal loans and a variety of consumer loans. 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. Related Party Loans. In the normal course of business, the Company makes loans to certain officers, directors and their associated companies, under terms that are consistent with the Company’s lending policies and regulatory requirements and do not involve more than the normal risk of collectability or present other unfavorable features. At December 31, 2022 and 2021, outstanding loans to certain officers, directors and their associated companies were less than 5% of the Company's shareholders' equity. ACL on Loans The Company manages its loan portfolio proactively to effectively identify problem credits and assess trends early, implement effective work-out strategies, and take charge-offs as promptly as practical. In addition, the Company continuously reassesses its underwriting standards in response to credit risk posed by changes in economic conditions. The Company monitors and manages credit risk through the following governance structure: • The Credit Risk team, Collection and Special Assets team and the Credit Risk Policy Committee, which is an internal management committee comprised of various executives and senior managers across business lines, including Accounting and Finance, Credit Underwriting, Collections and Special Assets, Risk, and Commercial and Retail Banking, oversee the Company's systems and procedures to monitor the credit quality of its loan portfolio, conduct a loan review program, and maintain the integrity of the loan rating system. • The adequacy of the ACL is overseen by the Management Provision Committee, which is an internal management committee comprised of various Company executives and senior managers across business lines, including Accounting and Finance, Credit Underwriting, Collections and Special Assets, Compliance, and Commercial and Retail Banking. 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 December 31, 2022 and 2021, the Company's loan portfolio segments, as determined based on the unique risk characteristics of each, included 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. Also included within the non-owner-occupied commercial real estate loan segment are construction projects until they are completed. 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 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 are primarily paid by the operating cash flow of the borrower. Commercial loans may be secured or unsecured. SBA PPP. SBA PPP loans are unsecured, fully-guaranteed commercial loans backed by the SBA, issued to qualifying small businesses as part of federal stimulus issued in response to the COVID-19 pandemic. Loans made under the program have terms of two or five years and are to be used by the borrower to offset certain payroll and other operating costs, such as rent and utilities. The loan and accrued interest, or a portion thereof, is eligible for forgiveness by the SBA should the qualifying small business meet certain conditions. These loans were originated under the guidance of the SBA, which has been subject to change. Effective May 31, 2021, the SBA PPP loan program ended and the Company is no longer originating loans under this program. At December 31, 2022, five loans remained outstanding with a total principal balance of $632,000. 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. The home equity loan has a fixed rate and is billed as equal payments comprised of principal and interest. The 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 including 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. Borrower qualifications include favorable credit history combined with supportive income and collateral requirements within established policy guidelines, as applicable. Consumer loans may be secured or unsecured. ACL on Loans. The following table presents the activity in the ACL on loans, as reported under CECL, for the periods indicated: Commercial Real Estate (In thousands) Non-Owner-Occupied Owner- Occupied Commercial SBA PPP Residential Real Estate Home Equity Consumer Total At or For the Year Ended December 31, 2022 Beginning balance, December 31, 2021 $ 18,834 $ 2,539 $ 4,183 $ 19 $ 6,133 $ 1,469 $ 79 $ 33,256 Loans charged-off — — (1,042) — (66) — (134) (1,242) Recoveries 3 2 379 — — 87 7 478 (Credit) provision for loan losses (1,541) (179) 1,925 (18) 3,022 669 552 4,430 Ending balance, December 31, 2022 $ 17,296 $ 2,362 $ 5,445 $ 1 $ 9,089 $ 2,225 $ 504 $ 36,922 At or For the Year Ended December 31, 2021 Beginning balance, December 31, 2020 $ 21,778 $ 2,832 $ 6,703 $ 69 $ 3,474 $ 2,616 $ 393 $ 37,865 Loans charged-off — — (799) — (92) (162) (111) (1,164) Recoveries — 9 220 — 107 4 32 372 (Credit) provision for loan losses (2,944) (302) (1,941) (50) 2,644 (989) (235) (3,817) Ending balance, December 31, 2021 $ 18,834 $ 2,539 $ 4,183 $ 19 $ 6,133 $ 1,469 $ 79 $ 33,256 In the fourth quarter of 2022, the Company completed its annual reassessment of significant model inputs and assumptions within its discounted cash flow analysis used for estimating its ACL on loans as of December 31, 2022. The Company has engaged with a third party to help provide economic forecasts that align with management’s expectations to help drive the model and allows the Company to use qualitative factors to use multiple economic scenarios. This update enhanced the quantitative model and allowed the Company to eliminate certain other qualitative factors. The ACL on loans at December 31, 2022, was $36.9 million, an increase of $3.6 million, or 11%, since December 31, 2021. As of December 31, 2022 and 2021, the significant model inputs and assumptions used within the discounted cash flow model for purposes of estimating the ACL on loans were: • Macroeconomic (loss) drivers: As of December 31, 2022 and 2021, the following loss drivers for each loan segment were used to calculate the expected PD over the forecast and reversion period: (i) commercial real estate – non-owner-occupied used Maine Unemployment and change in Maine GDP; (ii) commercial real estate – owner-occupied used Maine Unemployment and change in Maine GDP, (iii) commercial used Maine Unemployment and change in National GDP; (iv) residential real estate used Maine Unemployment and change in Maine House Price Index, (v) home equity used Maine Unemployment and change in Maine House Price Index and (vi) consumer used Maine Unemployment and change in National GDP. Though the SBA PPP loans are fully guaranteed by the SBA, the Company applied an insignificant expected credit loss factor to its SBA PPP loan segment based on its past historical experience with similar loans and guarantees as of December 31, 2022 and 2021. • Reasonable and Supportable Forecast Period: As of December 31, 2022 and 2021, the ACL on loans estimate used a reasonable and supportable forecast period of one year. • Reversion Period: As of December 31, 2022 and 2021, the ACL on loans estimate used a reversion period of one year. • Prepayment Speeds: The estimate of prepayment speed for each loan segment continued to be derived used internally-sourced prepayment data as of December 31, 2022 and 2021. • Qualitative Factors: As of December 31, 2022 and 2021, the ACL on loans estimate incorporated various qualitative factors into the calculation. The ACL on loans at December 31, 2022, was $36.9 million, compared to $33.3 million at December 31, 2021. The overall increase in ACL was driven by the increase in the volume of loans, coupled with the volatility of the global markets and the high degree of uncertainty. Given the strong loan growth and the future economic uncertainty, the reserve increased $3.6 million during 2022. This increase was partially offset by the release of certain qualitative factors due to strong asset quality and the continued maturity of the overall model. The increase in the reserve represents the elevated risk of credit loss within the Company's portfolio. 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. As of December 31, 2022, the Company's total exposure to the lessors of nonresidential buildings' industry and lessors of residential buildings’ industry were 14% and 11% of total loans and 34% and 28% of total commercial real estate loans, respectively. There were no other industry concentrations exceeding 10% of the Company's total loan portfolio as of December 31, 2022. 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, are considered non-performing. Based on the most recent analysis performed, the risk category of loans by portfolio segment by vintage, reported under the CECL methodology, was as follows as of the periods indicated: (In thousands) 2022 2021 2020 2019 2018 Prior Revolving Loans Revolving Loans Total As of December 31, 2022 Commercial real estate - non-owner-occupied Risk rating Pass (Grades 1-6) $ 339,171 $ 287,749 $ 160,621 $ 125,029 $ 108,823 $ 242,024 $ — $ — $ 1,263,417 Special mention (Grade 7) — 167 364 259 75 321 — — 1,186 Substandard (Grade 8) — 127 1,306 203 7,798 18,406 — — 27,840 Doubtful (Grade 9) — — — — — — — — — Total commercial real estate - non-owner-occupied 339,171 288,043 162,291 125,491 116,696 260,751 — — 1,292,443 Commercial real estate - owner-occupied Risk rating Pass (Grades 1-6) 60,127 80,781 28,378 23,381 39,554 70,568 — — 302,789 Special mention (Grade 7) — 2,053 — 19,992 — 411 — — 22,456 Substandard (Grade 8) 17 — — — 3,266 3,966 — — 7,249 Doubtful (Grade 9) — — — — — — — — — Total commercial real estate - owner-occupied 60,144 82,834 28,378 43,373 42,820 74,945 — — 332,494 Commercial Risk rating Pass (Grades 1-6) 73,537 69,478 32,272 33,491 22,271 26,245 135,157 30,191 422,642 Special mention (Grade 7) — — 93 141 70 189 1,196 12 1,701 Substandard (Grade 8) 149 52 133 216 846 1,524 50 2,186 5,156 Doubtful (Grade 9) — — — — — — — — — Total commercial 73,686 69,530 32,498 33,848 23,187 27,958 136,403 32,389 429,499 SBA PPP Risk rating Pass (Grades 1-6) — 632 — — — — — — 632 Special mention (Grade 7) — — — — — — — — — Substandard (Grade 8) — — — — — — — — — Doubtful (Grade 9) — — — — — — — — — Total SBA PPP — 632 — — — — — — 632 Residential Real Estate Risk rating Pass (Grades 1-6) 533,035 579,216 244,691 79,492 50,214 210,262 340 — 1,697,250 Special mention (Grade 7) — — — — — 23 — — 23 Substandard (Grade 8) — — — — 163 2,830 — — 2,993 Doubtful (Grade 9) — — — — — — — — — Total residential real estate 533,035 579,216 244,691 79,492 50,377 213,115 340 — 1,700,266 Home equity Risk rating Performing 26,712 693 341 4,842 7,730 8,551 173,338 11,735 233,942 Non-performing — — — — — 27 377 82 486 Total home equity 26,712 693 341 4,842 7,730 8,578 173,715 11,817 234,428 Consumer Risk rating Performing 8,009 3,816 1,702 1,188 345 2,462 3,069 — 20,591 Non-performing — — — — — — — — — Total consumer 8,009 3,816 1,702 1,188 345 2,462 3,069 — 20,591 Total Loans $ 1,040,757 $ 1,024,764 $ 469,901 $ 288,234 $ 241,155 $ 587,809 $ 313,527 $ 44,206 $ 4,010,353 (In thousands) 2021 2020 2019 2018 2017 Prior Revolving Loans Revolving Loans Total As of December 31, 2021 Commercial real estate - non-owner-occupied Risk rating Pass (Grades 1-6) $ 286,428 $ 179,565 $ 161,695 $ 118,196 $ 96,169 $ 274,731 $ — $ — $ 1,116,784 Special mention (Grade 7) 171 7,266 286 119 4,294 10,590 — — 22,726 Substandard (Grade 8) 350 1,518 217 9,942 391 26,257 — — 38,675 Doubtful (Grade 9) — — — — — — — — — Total commercial real estate - non-owner-occupied 286,949 188,349 162,198 128,257 100,854 311,578 — — 1,178,185 Commercial real estate - owner-occupied Risk rating Pass (Grades 1-6) 91,328 39,082 31,409 43,786 46,466 56,682 — — 308,753 Special mention (Grade 7) — — — 3,396 362 1,708 — — 5,466 Substandard (Grade 8) — — 54 — 1,785 1,217 — — 3,056 Doubtful (Grade 9) — — — — — — — — — Total commercial real estate - owner-occupied 91,328 39,082 31,463 47,182 48,613 59,607 — — 317,275 Commercial Risk rating Pass (Grades 1-6) 91,102 43,757 44,925 23,895 13,818 27,743 80,775 31,586 357,601 Special mention (Grade 7) 145 117 590 115 383 222 967 244 2,783 Substandard (Grade 8) — 339 320 492 293 1,209 360 298 3,311 Doubtful (Grade 9) — — — — — — — — — Total commercial 91,247 44,213 45,835 24,502 14,494 29,174 82,102 32,128 363,695 SBA PPP Risk rating Pass (Grades 1-6) 35,164 319 — — — — — — 35,483 Special mention (Grade 7) 470 — — — — — — — 470 Substandard (Grade 8) — — — — — — — — — Doubtful (Grade 9) — — — — — — — — — Total SBA PPP 35,634 319 — — — — — — 35,953 Residential Real Estate Risk rating Pass (Grades 1-6) 586,637 281,804 103,228 63,403 46,696 219,983 903 — 1,302,654 Special mention (Grade 7) — — — — — 230 — — 230 Substandard (Grade 8) — — — — — 3,563 — — 3,563 Doubtful (Grade 9) — — — — — — — — — Total residential real estate 586,637 281,804 103,228 63,403 46,696 223,776 903 — 1,306,447 Home equity Risk rating Performing 760 554 6,179 10,995 2,464 10,792 165,189 12,295 209,228 Non-performing — — — 41 — 174 847 113 1,175 Total home equity 760 554 6,179 11,036 2,464 10,966 166,036 12,408 210,403 Consumer Risk rating Performing 6,860 3,523 3,089 1,051 548 2,014 2,399 — 19,484 Non-performing — 9 21 — — 2 — — 32 Total consumer 6,860 3,532 3,110 1,051 548 2,016 2,399 — 19,516 Total Loans $ 1,099,415 $ 557,853 $ 352,013 $ 275,431 $ 213,669 $ 637,117 $ 251,440 $ 44,536 $ 3,431,474 Past Due and Non-Accrual Loans. The Company closely monitors the performance of its loan portfolio. A loan is placed on non-accrual 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, all other loans to the borrower are re-evaluated to determine if they should also be placed on non-accrual. All previously accrued and unpaid interest is reversed at this time. A loan will return to accrual 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 because they are 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 Past Due 60 – 89 Days Past Due 90 Days or Greater Past Due Total Past Due Current Total Loans Outstanding Loans > 90 Days Past Due and Accruing 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 67 640 1,374 428,125 429,499 — SBA PPP — 67 — 67 565 632 — 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 $ — December 31, 2021: Commercial real estate - non-owner-occupied $ — $ — $ 51 $ 51 $ 1,178,134 $ 1,178,185 $ — Commercial real estate - owner-occupied 47 — 133 180 317,095 317,275 — Commercial 282 174 787 1,243 362,452 363,695 — SBA PPP — 68 — 68 35,885 35,953 — Residential real estate 379 475 1,210 2,064 1,304,383 1,306,447 — Home equity 456 50 445 951 209,452 210,403 — Consumer 95 1 32 128 19,388 19,516 — Total $ 1,259 $ 768 $ 2,658 $ 4,685 $ 3,426,789 $ 3,431,474 $ — The following table presents the amortized cost basis of loans on non-accrual status (including non-accruing TDRs) by portfolio segment as of the dates indicated: December 31, 2022 2021 (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 $ — $ 11 $ 11 $ 38 $ 13 $ 51 Commercial real estate - owner-occupied — 46 46 86 47 133 Commercial 415 300 715 785 44 829 Residential real estate 1,314 419 1,733 1,780 327 2,107 Home equity 421 65 486 1,064 111 1,175 Consumer — — — 32 — 32 Total $ 2,150 $ 841 $ 2,991 $ 3,785 $ 542 $ 4,327 The following table presents the amortized cost basis of collateral-dependent non-accrual loans (including non-accruing TDRs) by portfolio segment and collateral type, as of the date indicated: December 31, December 31, Collateral Type Total Collateral -Dependent Non-Accrual Loans Collateral Type Total Collateral -Dependent Non-Accrual Loans (In thousands) Real Estate Real Estate Residential real estate $ 387 $ 387 $ 268 $ 268 Home equity — — 111 111 Total $ 387 $ 387 $ 379 $ 379 Collateral-dependent loans are loans for which the 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 for the years ended December 31, 2022, 2021, and 2020 is estimated to have been $145,000, $256,000, and $335,000, respectively. The Company's policy is to reverse previously recorded interest income when a loan is placed on non-accrual, as such, the Company did not record any interest income on its non-accrual for the years ended December 31, 2022, 2021, and 2020. As of December 31, 2022 and 2021, total accrued interest receivable on loans, which has been excluded from reported amortized cost basis on loans, was $10.3 million and $7.8 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. TDRs. The Company takes a conservative approach with credit risk management and remains focused on community lending and reinvesting. The Company works closely with borrowers experiencing credit problems to assist in loan repayment or term modifications. TDR loans consist 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, involve 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, by portfolio segment, and the associated specific reserve included within the ACL for the dates indicated: Number of Contracts Recorded Investment Specific Reserve (In thousands, except number of contracts) December 31, December 31, December 31, 2022 2021 2022 2021 2022 2021 Commercial real estate - owner-occupied 1 1 $ 113 $ 118 $ 50 $ 43 Commercial — 2 — 74 — — Residential real estate 18 19 2,208 2,341 307 348 Consumer and home equity 3 3 245 253 9 6 Total 22 25 $ 2,566 $ 2,786 $ 366 $ 397 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.

For the years ended December 31, 2022, 2021 and 2020, no loans were modified as TDRs within the previous 12 months for which the borrower subsequently defaulted. Effective January 1, 2023, the Company adopted ASU No. 2022-02, Financial Instruments - Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures ("ASU 2022-02") which eliminates the TDR recognition and measurement guidance and now requires the Company to evaluate if any modifications represent a new loan or continuation of an existing loan. Refer to Note 1 of the consolidated financial statements for further discussion of the Company's accounting recently adopted policy for the TDRs. In-Process Foreclosure Proceedings

Leases [Abstract]
Leases	LEASES The Company enters into noncancellable lease arrangements primarily for office space, space for ATM locations and some of its branches. Certain lease arrangements contain clauses requiring increasing rental payments over the lease term, which may be linked to an index (commonly the Consumer Price Index) or contractually stipulated. The Company's lease agreements do not contain any material residual value guarantees or material restrictive covenants. The Company entered into a lease arrangement with two of its employees as landlords. The lease was renewed for a period of five years, expiring in 2024, at which time a five-year extension period is available at the option of the Company. The lease arrangement contains certain termination clauses whereby the Company has the right to terminate the lease arrangement, as well as a right to terminate the lease after two years with the required notice without penalty. The Company entered into a lease agreement in 2019 to rent office space as a sub-tenant from another company in which a director of the Company serves as the Chairman and Chief Executive Officer of the other company.

Mortgage Banking

Transfers and Servicing [Abstract]
Mortgage Banking	MORTGAGE BANKING Loans Sold For the years ended December 31, 2022, 2021 and 2020, the Company sold $152.7 million, $471.5 million and $625.5 million, respectively, of residential mortgage loans on the secondary market, which resulted in a net gain on sale of loans (net of costs, including direct and indirect origination costs) of $3.4 million, $13.3 million, and $15.3 million, respectively. Loans Held for Sale At December 31, 2022 and 2021, the Company had identified and designated loans with an unpaid principal balance of $5.3 million and $5.8 million, respectively, as held for sale. The Company has elected the fair value option of accounting for its loans designated as held for sale, and, at December 31, 2022 and 2021, the unrealized (loss) gain recorded was ($62,000) and $29,000, respectively. The unrealized gain or loss on its loans held for sale portfolio was driven by changes in market interest rates and not due to deteriorated credit quality as this risk is mitigated by the short duration between the time of loan closing and transfer of the financial assets to the secondary market investor. Included within the Company's mortgage banking income, net on the consolidated statements of income for the years ended December 31, 2022, 2021 and 2020 was the change in unrealized (losses) gains on loans held for sale of ($91,000), ($1.0) million and $1.1 million, respectively. The Company mitigates its interest rate exposure on its loans designated as held for sale through forward delivery commitments with certain approved secondary market investors at the onset of the mortgage origination process, typically on a “best-efforts” basis. For the years ended December 31, 2022, 2021 and 2020, net unrealized gains (losses) from the change in fair value on its forward delivery commitments were $140,000, ($35,000), and ($182,000), respectively. Refer to Note 12 for further discussion of the Company's forward delivery commitments. Servicing Assets At December 31, 2022 and 2021, the Company's unpaid principal balances on its servicing assets were $389.4 million and $411.9 million, respectively. For the years ended December 31, 2022, 2021 and 2020, the Company recorded servicing fee income for its servicing assets of $1.2 million, $1.3 million and $1.0 million, respectively, which was presented in mortgage banking income, net on the consolidated statements of income. The Company's servicing assets, net of a valuation allowance, at December 31, 2022 and 2021 was $2.5 million. Servicing assets, net of a valuation allowance, are presented in other assets on the consolidated statements of condition. The Company obtains third party valuations of its servicing assets portfolio quarterly. The servicing assets valuation is based on loan level data stratified by note rate of the underlying loans to determine its amortization and fair value. A discounted cash flow model is used to value each servicing asset strata and it incorporates current market assumption commonly used by buyers of these types of mortgage production in U.S. servicing markets. The calculated valuation using the discounted cash flow method is then compared to recent servicing trades on portfolios with similar characteristics in the U.S. The valuation model utilizes a variety of assumptions, the most significant of which are loan prepayment assumptions and the discount rate used to discount future cash flows. At December 31, 2022 and 2021, the prepayment assumption used within the valuation model was 7.5% and 12.9%, respectively, and the discount rate was 9.6% for both years. At December 31, 2022, the estimated effect of a 10% and 20% increase to the prepayment assumption was a decrease of $137,000 and $266,000, respectively, to the valuation of the servicing assets. At December 31, 2022, the estimated effect of a 100 and 200 basis point increase to the discount rate assumption was a decrease of $175,000 and $338,000, respectively, to the valuation of the servicing assets. Other assumptions include, but are not limited to, delinquency rates, foreclosure rates, and loan servicing cost. The following summarizes servicing assets capitalized and amortized, along with the activity in the related valuation allowance as of and for the periods indicated: As of and For the Year Ended (In thousands) 2022 2021 2020 Servicing Assets: Balance at beginning of year $ 2,470 $ 2,196 $ 877 Capitalized servicing right fees upon sale (1) 370 790 1,763 Amortization charged against mortgage servicing fee income (2) (382) (515) (419) Valuation adjustment — (1) (25) Balance at end of year $ 2,458 $ 2,470 $ 2,196 Valuation Allowance: Balance at beginning of year $ (1) $ (27) $ (2) Decrease (increase) in impairment reserve 1 26 (25) Balance at end of year $ — $ (1) $ (27) Fair value, beginning of year $ 3,310 $ 2,447 $ 1,496 Fair value, end of year $ 4,412 $ 3,310 $ 2,447 (1) Associated income was reported within mortgage banking income, net on the consolidated statements of income. (2) Associated amortization expense was reported within mortgage banking income, net on the consolidated statements of income. Servicer Net Worth and Liquidity Requirements. The Bank, as a servicer of loans, must maintain certain net worth and liquidity requirements for certain agencies and certain secondary market investors. As lender and servicer of Federal Housing Authority (“FHA”) loans, the Bank is required to maintain a minimum net worth of $1.0 million plus 1.0% of total FHA loans exceeding $25.0 million (“minimum net worth required”) and maintain liquid assets equal to at least 20.0% of its minimum net worth required. The Bank is required to maintain a minimum net worth of $2.5 million plus 25 basis points of the unpaid principal balance of serviced loans and must meet the minimum regulatory capital requirement to be classified as “well capitalized” by both FNMA and FHLMC. Should the Bank fail to maintain the net worth and liquidity requirements above, the secondary market investor may take remedial action and the Company may lose the right to service the loans, which may result in an impairment of its servicing assets and/or loss of revenue. At December 31, 2022 and 2021, the Bank met all of the aforementioned minimum net worth, regulatory capital, and liquidity requirements. Refer to Note 14 for further details of the Company and Bank's regulatory capital requirements at December 31, 2022 and 2021.

FHLBB Borrowings The terms of the Company's outstanding FHLBB borrowings, including overnight funding, were as follows as of December 31, 2022. The Company had no FHLBB borrowings at December 31, 2021. December 31, (Dollars in thousands) 2022 Stated Maturity Outstanding Balance Weighted Average Contractual Rate January 2023 $ 18,725 4.38 % March 2023 50,000 4.93 % Total $ 68,725 In February 2021, the Company terminated its $25.0 million FHLBB borrowing contract, with a maturity date in 2025, and incurred a one-time prepayment penalty of $514,000. FHLBB borrowings, if any, are collateralized by a blanket lien on qualified collateral consisting primarily of loans with first mortgages secured by one-to-four family properties, certain commercial real estate loans, certain pledged investment securities and other qualified assets. The carrying value of residential real estate and commercial loans pledged as collateral was $1.8 billion and $1.4 billion at December 31, 2022 and 2021, respectively. The carrying value of investment securities pledged as collateral at the FHLBB was $22,000 and $26,000 at December 31, 2022 and 2021, respectively. Junior Subordinated Debentures In April 2006, the Company formed CCTA, which issued and sold trust preferred securities to the public. The Company received $36.1 million from the issuance of the trust preferred securities in return for junior subordinated debentures issued by the Company to CCTA. The Company owns all of the $1.1 million of outstanding common securities of CCTA and was presented within other assets on the consolidated statements of condition. The contract interest rate of the trust preferred securities is three-month LIBOR plus 140 basis points, and in accordance with the LIBOR Act effective June 30, 2023, the index will transition to three month CME term SOFR plus the spread adjustment of 26.161 basis points. At December 31, 2022 and 2021, the interest rate on the trust preferred securities was 5.07% and 1.62%, respectively. The proceeds from the offering were used to repurchase Company common stock under the tender offer completed in May 2006. The trust preferred securities, which pay interest quarterly at the same rate as the junior subordinated debentures held by CCTA, are mandatorily redeemable on June 30, 2036, or may be redeemed by CCTA at par at any time. In connection with an acquisition in 2008, the Company assumed $8.0 million of trust preferred securities, held through a Delaware trust affiliate, UBCT. In 2006, an aggregate principal amount of $8.2 million of 30-year junior subordinated debt securities were issued to UBCT. The Company owns all of the $248,000 of outstanding common securities of UBCT, and was presented within other assets on the consolidated statements of condition. The Company is obligated to pay interest on their principal sum quarterly. The contract interest rate of the trust preferred securities is three-month LIBOR plus 1.42%, and in accordance with the LIBOR Act effective June 30, 2023 the index will transition to three month CME term SOFR plus the spread adjustment of 26.161 basis points. At December 31, 2022 and 2021, the interest rate on the trust preferred securities was 5.50% and 1.54%, respectively. The debt securities mature on April 7, 2036, but may be redeemed by the Company at par, in whole or in part, on any interest payment date. The debt securities may also be redeemed by the Company in whole or in part, within 90 days of the occurrence of certain special redemption events. CCTA and UBCT are Delaware statutory trusts created for the sole purpose of issuing trust preferred securities and investing the proceeds in junior subordinated debentures of the Company. The junior subordinated debentures are the sole assets of the trusts. The Company is the owner of all of the common securities of CCTA and UBCT and fully and unconditionally guarantees each trust’s securities obligations. In accordance with GAAP, CCTA and UBCT are treated as unconsolidated subsidiaries. The common stock investment in the statutory trusts is included in other assets on the consolidated statements of condition. At December 31, 2022, $43.0 million of the trust preferred securities were included in the Company’s total Tier 1 capital and amounted to 8.3% of Tier 1 capital of the Company, or 106 basis points of the Tier 1 capital ratio. The Company has a notional amount of $43.0 million in interest rate swap agreements on its junior subordinated debentures. Further discussion on the terms and accounting for the interest rate swap agreements is included within Note 12 of the consolidated financial statements. Interest expense on the subordinated debentures, including the effective portion of the associated interest rate swaps on these debt instruments reclassified from OCI into earnings, totaled $2.1 million, $2.5 million, and $3.5 million for the years ended December 31, 2022, 2021 and 2020, respectively. Refer to Note 12 of the consolidated financial statements for information pertaining to the reclassification of OCI into earnings on the interest rate swaps. Credit Lines At December 31, 2022, the Company has the following lines of credit available to it, for which it had no outstanding balances: • The Bank had an available line of credit with the FHLBB of $9.9 million at December 31, 2022 and 2021. This line of credit serves as overdraft protection should the Company overdraw its account with the FHLBB. The interest rate for this line of credit is set daily by the FHLBB. • The Company has an unsecured $10.0 million line of credit with PNC Bank that has a maturity date of December 15, 2023, for which the interest rate is SOFR-based and is set daily by PNC Bank. • The Company, through the Bank, has an unsecured $50.0 million line of credit with PNC Bank for which the interest rate is set daily by PNC Bank. • The Company, through the Bank, has a secured line of credit of $42.4 million through the FRB's Discount Window for which the interest rate is set by the FRB daily. At December 31, 2022, the Bank pledged investment securities of $51.4 million.

Repurchase Agreements

Banking and Thrift, Other Disclosure [Abstract]
Repurchase Agreements	REPURCHASE AGREEMENTSThe 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 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 as interest expense on the consolidated statements of income. The securities underlying the agreements are delivered to counterparties as security 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, allocated by source of collateral, as of the dates indicated: December 31, (In thousands) 2022 2021 Customer Repurchase Agreements (1)(2) : Mortgage-backed securities issued or guaranteed by U.S. government-sponsored enterprises $ 99,105 $ 120,846 Collateralized mortgage obligations issued or guaranteed by U.S. government-sponsored enterprises 94,328 88,749 Obligations of states and political subdivisions 3,018 2,013 Total $ 196,451 $ 211,608 (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 December 31, 2022 and 2021, certain customers held CDs totaling $616,000 and $728,000, 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: December 31, (In thousands) 2022 2021 Commitments to extend credit $ 817,772 $ 834,533 Standby letters of credit 6,801 7,952 Total $ 824,573 $ 842,485 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 December 31, 2022 and 2021, the ACL on off-balance sheet credit exposures was $3.3 million and $3.2 million, respectively. The ACL on off-balance sheet credit exposures was presented within accrued interest and other liabilities on the consolidated statements of condition. For the years ended December 31, 2022, 2021 and 2020, the provision (credit) for credit losses on off-balance sheet credit exposures was $70,000, $627,000 and ($797,000), respectively. Refer to Note 1 of the consolidated financial statements for further discussion of the Company's accounting policy for the ACL on off-balance sheet credit exposures. 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 December 31, 2022 and 2021.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives and Hedging	DERIVATIVES AND HEDGING The 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 - Cash Flow Hedges of Interest Rate Risk Interest Rate Contracts. 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 years ended December 31, 2022 and 2021, 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 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 $3.0 million will be reclassified as a decrease to interest expense and an additional $3.1 million will be reclassified as a decrease to interest income over the next 12 months. 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 December 31, 2022 and 2021, 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 $14.8 million and $26.1 million, respectively. As of December 31, 2022 and 2021, the Company has minimum collateral posting thresholds with certain of its derivative counterparties and has posted cash collateral of $0 and $30.7 million, respectively. If the Company had breached any of these provisions at December 31, 2022 or 2021, it could have been required to settle its obligations under the agreements at their termination value of $14.8 million and $26.1 million, respectively. Subsequent to December 31, 2022, the Company executed four fixed-for-floating interest rate swaps for a total of $300.0 million of notional on a designated pool of fixed rate residential real estate loans. The derivative transaction was designated as a “fair value hedge” under ASC 815.

Offsetting [Abstract]
Balance Sheet Offsetting	DERIVATIVES AND HEDGING The 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 - Cash Flow Hedges of Interest Rate Risk Interest Rate Contracts. 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 years ended December 31, 2022 and 2021, 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 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 $3.0 million will be reclassified as a decrease to interest expense and an additional $3.1 million will be reclassified as a decrease to interest income over the next 12 months. 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 December 31, 2022 and 2021, 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 $14.8 million and $26.1 million, respectively. As of December 31, 2022 and 2021, the Company has minimum collateral posting thresholds with certain of its derivative counterparties and has posted cash collateral of $0 and $30.7 million, respectively. If the Company had breached any of these provisions at December 31, 2022 or 2021, it could have been required to settle its obligations under the agreements at their termination value of $14.8 million and $26.1 million, respectively. Subsequent to December 31, 2022, the Company executed four fixed-for-floating interest rate swaps for a total of $300.0 million of notional on a designated pool of fixed rate residential real estate loans. The derivative transaction was designated as a “fair value hedge” under ASC 815.

Shareholders' Equity

Shareholders' Equity	12 Months Ended
	Dec. 31, 2022
Stockholders' Equity Note [Abstract]
Shareholders' Equity	SHAREHOLDERS' EQUITY 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 capital rules, 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 December 31, 2022 and 2021, and the Bank's capital ratios met the requirements for the Bank 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 December 31, 2022 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: December 31, 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” Amount Ratio Amount Ratio Camden National Corporation: Total risk-based capital ratio $ 557,571 13.80 % 10.50 % 10.00 % $ 522,714 14.71 % 10.50 % 10.00 % Tier 1 risk-based capital ratio 517,385 12.81 % 8.50 % 6.00 % 486,263 13.68 % 8.50 % 6.00 % Common equity Tier 1 risk-based capital ratio (1) 474,385 11.74 % 7.00 % N/A 443,263 12.47 % 7.00 % N/A Tier 1 leverage capital ratio (1) 517,385 9.22 % 4.00 % N/A 486,263 8.92 % 4.00 % N/A Camden National Bank: Total risk-based capital ratio $ 525,346 13.03 % 10.50 % 10.00 % $ 488,070 13.78 % 10.50 % 10.00 % Tier 1 risk-based capital ratio 485,160 12.03 % 8.50 % 8.00 % 451,620 12.75 % 8.50 % 8.00 % Common equity Tier 1 risk-based capital ratio 485,160 12.03 % 7.00 % 6.50 % 451,620 12.75 % 7.00 % 6.50 % Tier 1 leverage capital ratio 485,160 8.65 % 4.00 % 5.00 % 451,620 8.31 % 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 December 31, 2022 and 2021, $43.0 million of the junior subordinated debentures were induced 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 impact of proposed and pending changes as a result of new and/or amended GAAP standards and regulatory changes. Dividends The primary source of funds available to the Company for the payment of dividends to its shareholders is dividends paid to the Company by its wholly-owned subsidiary, the Bank. The Bank is subject to certain requirements imposed by federal banking laws and regulations. These requirements, among other things, establish minimum levels of capital and restrict the amount of dividends that a bank subsidiary may distribute. Under OCC regulations, the Bank generally may not declare a dividend in excess of the Bank's undivided profits or, absent OCC approval, if the total amount of dividends declared by the Bank in any calendar year exceeds the total of the Bank's net income for the current year plus its retained net income for the prior two years. For the years ended December 31, 2022, 2021, and 2020, the Bank declared dividends for payment to the Company in the amount of $31.7 million, $41.7 million, and $39.4 million, respectively. For the years ended December 31, 2022, 2021 and 2020, the Company declared $23.7 million, $22.1 million and $19.8 million, respectively, in dividends payable to its shareholders. Common Stock Repurchase In January 2020, the Company's Board of Directors authorized the repurchase of up to 750,000 shares of the Company's common stock, representing approximately 5.0% of the Company's issued and outstanding shares of common stock as of December 31, 2019. For the year ended December 31, 2020, the Company purchased 274,354 shares of its common stock at a weighted-average price of $35.36. This program has since terminated. In February 2021, the Company's Board of Directors authorized the repurchase of up to 750,000 shares of the Company's common stock, representing approximately 5.0% of the Company's issued and outstanding shares of common stock as of December 31, 2020. For the year ended December 31, 2021, the Company purchased 217,931 shares of its common stock at a weighted-average price of $46.25. This program terminated on January 3, 2022. In January 2022, the Company's Board of Directors authorized the repurchase of up to 750,000 shares of the Company's common stock, representing approximately 5.0% of the Company's issued and outstanding shares of common stock as of December 31, 2021. For the year ended December 31, 2022, the Company purchased 225,245 shares of its common stock at a weighted-average price of $45.46. This program terminated on January 3, 2023. On January 3, 2023, the Company's Board of Directors authorized the repurchase of up to 750,000 shares of the Company's common stock, representing approximately 5.0% of the Company's issued and outstanding shares of common stock as of December 31, 2022. This program replaces the 2022 program and will continue until the earlier of: (1) the authorized number of shares are repurchased, (2) the Company's Board of Directors terminates the program or (3) January 3, 2024.

Revenue from Contract with Customer [Abstract]
Revenue from Contracts with Customer	REVENUE FROM CONTRACTS WITH CUSTOMERS 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 customer within the scope of ASC 606 closely aligns with the presentation revenue categories presented within non-interest income on the consolidated statements of income. The following table presents the revenue streams with the scope of ASC 606 for the periods indicated: For the Year Ended (In thousands) Location on Consolidated 2022 2021 2020 Debit card interchange income Debit card income $ 13,340 $ 13,105 $ 10,420 Services charges on deposit accounts Service charges on deposit accounts 7,587 6,626 6,697 Fiduciary services income Income from fiduciary services 6,407 6,516 6,115 Investment program income Brokerage and insurance commissions 4,147 3,913 2,832 Other non-interest income Other income 1,793 1,794 1,672 Total non-interest income within the scope of ASC 606 33,274 31,954 27,736 Total non-interest income not in scope of ASC 606 7,428 17,781 22,754 Total non-interest income $ 40,702 $ 49,735 $ 50,490 In each of the revenue streams identified above, there were no significant judgments made in determining or allocating the transaction price, as the consideration and services are generally explicitly identified in the associated contracts. Additional information related to each revenue stream is discussed below. Debit Card Interchange Income. The Company has separate contracts with intermediaries and earns interchange revenue and incurs related expenses on debit card transactions of its deposit customers. Income earned and expenses incurred by the Company are dependent on its depositors' debit card usage, including depositor spend, transaction type and merchant. The rates earned are determined by the intermediaries. The Company determined that although the contract for which revenues are directly earned is with the intermediary rather than the depositor, that an underlying contract with each depositor is required for the generation of debit card interchange income and it is the depositors' debit card usage that drives the revenues earned and related expenses incurred. The contract with the depositor is day-to-day and can be closed by the customer or the Company at any time. As such, the Company recognizes revenue at the time of the transaction as the performance obligation has been met. The Company's debit card interchange revenue and related expenses are presented on a gross basis as it has control of the specified service prior to transfer to the depositor through the extension of credit. The Company pays to certain depositors cash rewards for debit card usage to promote usage and increase interchange revenue. Because the consideration paid to depositors is not for any separate or distinct service, these costs are accounted for as a reduction of debit card interchange income. For the years ended December 31, 2022, 2021 and 2020, cash rewards totaled $525,000, $477,000 and $603,000, respectively. Service charges on deposit accounts.

Due to Internal Revenue Code Section 382(g) limitations, the Company's use of the federal net operating losses acquired is limited to $3.9 million annually, which was determined using the applicable federal rate and the fair value of consideration paid for the acquisition at the acquisition date. The acquired federal net operating losses will expire between 2030 and 2034. The Company expects that it will be able to fully utilize the acquired allowable federal net operating losses prior to expiration, as the Company has a history of generating taxable income well in excess of the limitation. The Company continuously monitors and assesses the need for a valuation allowance on its deferred tax assets and, at December 31, 2022 and 2021 determined that no valuation allowance was necessary. As of December 31, 2022, the Company's federal and state income tax returns for the years ended December 31, 2021, 2020 and 2019 were open to audit by federal and state authorities.

Earnings per Share	EPS The following is an analysis of basic and diluted EPS, reflecting the application of the two-class method, as described below: For the Year Ended (In thousands, except number of shares and per share data) 2022 2021 2020 Net income $ 61,439 $ 69,014 $ 59,486 Dividends and undistributed earnings allocated to participating securities (1) (162) (190) (149) Net income available to common shareholders $ 61,277 $ 68,824 $ 59,337 Weighted-average common shares outstanding for basic EPS 14,644,170 14,903,855 14,985,235 Dilutive effect of stock-based awards (2) 56,840 67,723 38,532 Weighted-average common and potential common shares for diluted EPS 14,701,010 14,971,578 15,023,767 Earnings per common share: Basic EPS $ 4.18 $ 4.62 $ 3.96 Diluted EPS $ 4.17 $ 4.60 $ 3.95 Awards excluded from the calculation of diluted EPS (3) : Performance-based share units — 2,403 1,849 Stock options — — 1,000 (1) Represents dividends paid and undistributed earnings allocated to non-vested stock-based awards that contain non-forfeitable rights to dividends. (2) Represents the assumed dilutive effect of unexercised and/or unvested stock options, restricted shares and 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. Net income is allocated between the common stock and participating securities pursuant to the two-class method. Basic EPS is computed by dividing net income available to common shareholders by the weighted-average number of common shares outstanding during the period, excluding participating non-vested stock-based awards. Diluted EPS is computed in a similar manner, except that the denominator includes the number of additional common shares that would have been outstanding if potentially dilutive common shares were issued using the treasury stock method.

Fair Value

Fair Value Disclosures [Abstract]
Fair Value	FAIR VALUE 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 more clearly align 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 December 31, 2022 and 2021, 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 are 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 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 are 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 Value Readily Available Market Prices Observable Market Data Company Determined Fair Value December 31, 2022 Financial assets: Trading securities $ 3,990 $ 3,990 $ — $ — AFS debt securities: Obligations of states and political subdivisions 49,226 — 49,226 — Mortgage-backed securities issued or guaranteed by U.S. government-sponsored enterprises 514,019 — 514,019 — Collateralized mortgage obligations issued or guaranteed by U.S. government-sponsored enterprises 109,347 — 109,347 — Subordinated 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 — Forward delivery commitments — — — — December 31, 2021 Financial assets: Trading securities $ 4,428 $ 4,428 $ — $ — AFS debt securities: Obligations of U.S. government-sponsored enterprises 8,344 — 8,344 — Obligations of states and political subdivisions 117,478 — 117,478 — Mortgage-backed securities issued or guaranteed by U.S. government-sponsored enterprises 1,000,257 — 1,000,257 — Collateralized mortgage obligations issued or guaranteed by U.S. government-sponsored enterprises 358,849 — 358,849 — Subordinated corporate bonds 22,558 — 22,558 — Loans held for sale 5,815 — 5,815 — Customer loan swaps 19,297 — 19,297 — Interest rate contracts 5,589 — 5,589 — Fixed rate mortgage interest rate lock commitments 371 — 371 — Forward delivery commitments 86 — 86 — Financial liabilities: Deferred compensation $ 4,428 $ 4,428 $ — $ — Customer loan swaps 19,485 — 19,485 — Interest rate contracts 7,872 — 7,872 — Fixed rate mortgage interest rate lock commitments 91 — 91 — Forward delivery commitments 6 — 6 — The Company did not have any transfers between Level 1 and Level 2 of the fair value hierarchy for the years ended December 31, 2022 or 2021. 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 December 31, 2022 and 2021, 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 determined servicing assets are Level 3 of the fair value hierarchy. Non-Financial Instruments Recorded at Fair Value on a Nonrecurring Basis The Company had no non-financial assets or non-financial liabilities measured at fair value on a nonrecurring basis as of December 31, 2022 and 2021. Non-financial assets measured at fair value on a nonrecurring basis may 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 December 31, 2022 and December 31, 2021, 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. Through its assessments, management concluded goodwill was not impaired for the years ended December 31, 2022 or, 2021. Core Deposit Intangible Assets. 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 indications or triggering events for the years ended December 31, 2022 or 2021, 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: (In thousands) Carrying Amount Fair Value Readily Available Market Prices Observable Market Prices Company Determined Market Prices 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) 424,054 413,706 — — 413,706 SBA PPP loans (2) 631 647 — — 647 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 — Subordinated debentures 44,331 31,032 — 31,032 — December 31, 2021 Financial assets: HTM debt securities $ 1,291 $ 1,380 $ — $ 1,380 $ — Commercial real estate loans (1)(2) 1,474,087 1,435,794 — — 1,435,794 Commercial loans (2) 359,512 356,463 — — 356,463 SBA PPP loans (2) 35,934 37,133 — — 37,133 Residential real estate loans (2) 1,300,314 1,297,592 — — 1,297,592 Home equity loans (2) 208,934 205,920 — — 205,920 Consumer loans (2) 19,437 17,551 — — 17,551 Servicing assets 2,471 3,310 — — 3,310 Financial liabilities: Time deposits $ 409,668 $ 409,264 $ — $ 409,264 $ — Short-term borrowings 211,608 211,586 — 211,586 — Subordinated debentures 44,331 33,248 — 33,248 — (1) Commercial real estate loans includes non-owner-occupied and owner-occupied properties.

Business and Summary of Signi_2

Business and Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2022
Accounting Policies [Abstract]
Principles of Consolidation	Principles of Consolidation . The accompanying consolidated financial statements include the accounts of the Company and the Bank (which includes the consolidated accounts of 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, 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 CCTA and UBCT. These entities are unconsolidated subsidiaries of the Company.
Reclassifications	Reclassifications . Certain reclassifications have been made to prior year amounts, without impact to net income or total shareholders' equity, to conform to the current year's presentation.
Use of Estimates	Use of Estimates . The preparation of the financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could vary from these estimates as a result of changing conditions and future events. Several estimates are particularly critical and are susceptible to significant near-term change, such as the ACL, including the allowance for loan losses, off-balance sheet credit exposures, and AFS and HTM debt securities; the accounting for business combinations including subsequent impairment analyses for goodwill and other intangible assets; accounting for income taxes; and postretirement benefits.
Subsequent Events	Subsequent Events . The Company has evaluated events and transactions subsequent to December 31, 2022 for potential recognition or disclosure as required by GAAP and have been disclosed in Note 12.
Significant Concentration of Credit Risk	Significant Concentration of Credit Risk. The Company makes loans primarily to customers in Maine, Massachusetts and New Hampshire. Although it has a diversified loan portfolio, a large portion of the Company's loans are secured by commercial or residential real estate and are subject to real estate market volatility within these states. Furthermore, the debtors' ability to honor their contracts is highly dependent upon other economic factors throughout Maine, Massachusetts and New Hampshire. The Company does not generally engage in non-recourse lending and typically will require the principals of any commercial borrower to obligate themselves personally on the loan. Refer to Note 3 for further discussion of credit concentrations.
Cash, Cash Equivalents and Restricted Cash	Cash, Cash Equivalents and Restricted Cash . For the purpose of reporting, cash and cash equivalents consist of cash on hand and amounts due from banks. In March 2020, the FRB reduced its reserve requirement ratios to 0%, effectively eliminating cash reserve requirements for all depository institutions. Certain cash balances will be designated as restricted as required by certain contracts with unrelated third parties.
Investments	Investments. Debt investments for which the Company has the positive intent and ability to hold to maturity are classified as HTM and recorded at amortized cost on the consolidated statements of condition. Debt investments that are not classified as HTM or trading are classified as AFS and are carried at fair value on the Company's consolidated statements of condition with subsequent changes to fair value recorded within AOCI, net of tax. Trading securities and equity investments with a readily determinable fair value are carried at fair value on the Company's consolidated statements of condition, with the change in fair value recognized between periods recognized within net income on the consolidated statements of income. Purchase premiums and discounts are recognized in interest income on the consolidated statements of income using the interest method over the period to maturity or issuer call option date, if earlier, and are recorded on the trade date. Upon sale of an investment security, the realized gain or loss on the sale is recognized within non-interest income on the consolidated statements of income. The cost basis of our investments sold is determined using the specific identification method. ACL on (or Write-off of) AFS Debt Securities. Management assesses its AFS debt securities in an unrealized loss position for the following: (i) whether it intends to sell the security, or (ii) it is more likely than not that it will be required to sell the security before recovery of its amortized cost basis. If either of the criteria regarding intent or requirement to sell is met, the security’s amortized cost basis is written down to fair value through net income. For AFS debt securities that do not meet either of the two criteria, management evaluates whether the decline in fair value resulted from credit losses or other factors. In making this assessment, management considers the following: (i) the extent to which fair value is less than amortized cost, (ii) credit rating of the security, (iii) macroeconomic trends of the industry specific to the security, and (iv) any other adverse conditions specifically related to the security, among other factors. If this assessment indicates that a credit loss exists, the present value of cash flows expected to be collected from the security are compared to the amortized cost basis of the security. If the present value of cash flows expected to be collected is less than the amortized cost basis, a credit loss exists and an allowance on AFS debt securities is recorded for the credit loss, limited by the amount that the fair value is less than the amortized cost basis. When assessing an AFS debt security for credit loss, securities with identical CUSIPs are pooled together to assess for impairment using the average cost basis. Any impairment that has not been recorded through an allowance is recognized in AOCI. A change in the ACL on AFS debt securities or write-off of an AFS debt security, which may be in full or a portion thereof, is recorded as expense (credit) within provision for credit losses on the consolidated statements of income. Losses are charged against the allowance when management believes the uncollectibility of an AFS debt security is confirmed or when either of the criteria regarding intent or requirement to sell is met. As of December 31, 2022 and 2021, there was no allowance carried on the Company's AFS debt securities nor were there any permanent write-offs for the years ended December 31, 2022, 2021, or 2020. Refer to Note 2 of the consolidated financial statements for further discussion. ACL on (or Write-off of) HTM Debt Securities. The Company estimates expected credit losses on its HTM debt securities and carry an allowance for such. Management measures expected credit losses on HTM debt securities on a collective basis by major security types that share similar risk characteristics, which may include, but is not limited to, credit ratings, financial asset type, collateral type, size, effective interest rate, term, geographical location, industry, and vintage. The estimate of expected credit losses on the HTM portfolio is based on the expected cash flows of each individual CUSIP over its contractual life and considers historical credit loss information, current conditions and reasonable and supportable forecasts. Under ASU 2016-13 the Company has the ability to exclude certain securities when the historical credit loss information, adjusted for current conditions and forecasts, resulting in zero risk of nonpayment of the amortized cost basis of the security. The Company has evaluated and determined zero risk of nonpayment on all securities guaranteed by the U.S government agencies. Given the rarity of municipal and corporate bond defaults and losses, the Company will utilize external third party loss forecast models as the sole source of municipal and corporate bond default and loss rates. As with the loan portfolio, cash flows are modeled over a reasonable and supportable forecast period and then revert to the long-term average economic conditions on a straight line basis. Management may exercise discretion to make adjustments based on various qualitative factors. An HTM debt security is written-off in the period in which a determination is made that all or a portion of the financial asset is uncollectible. Any previously recorded allowance, if any, is reversed and then the amortized cost basis is written-down to the amount deemed to be collectible, if any. A change in the ACL on HTM debt securities or write-off of an HTM debt security, which may be in full or a portion thereof, is recorded as expense (credit) within provision for credit losses on the consolidated statements of income. As of December 31, 2022 and 2021, there was no allowance carried on the Company’s HTM debt securities nor were there any permanent write-offs for the years ended December 31, 2022, 2021, or 2020. Refer to Note 2 of the consolidated financial statements for further discussion. FHLBB and FRBB Stock. The Company, through the Bank, is a member of the FHLBB and FRBB, and, as a member, is required to hold a certain amount of FHLBB and FRB common stock. These equity stocks are non-marketable and are reported at cost within other investments on the consolidated statements of condition. The Company evaluates its FHLBB and FRB common stock for impairment based on the ultimate recoverability of the par value rather than by recognizing temporary declines in value.
Loans Held for Sale	Loans Held for Sale. The Company has elected the fair value option for loans classified as held for sale on the consolidated statements of condition. Designation of loans as held for sale is determined based on intent and is generally completed as the loans are underwritten. The fair value for loans held for sale is determined using quoted secondary market prices. Management consistently evaluates the Company's loan portfolio in conjunction with asset/liability management practices, and will opt to sell certain residential mortgage loans to manage the Company's interest rate exposure and for other business purposes, including generating fee income through mortgage sale gains and managing its liquidity position.
Loans Held for Investment and Acquired Loans	Loans Held for Investment and Acquired Loans . Loans held for investment are reported at amortized cost, adjusted for any partial charge-offs and net of any deferred loan fees or costs. Interest income is accrued based upon the daily principal amount outstanding, except for loans on non-accrual status. Loan fees and certain direct origination costs are deferred and amortized into interest income over the contractual term of the loan using the level-yield method. When a loan is paid off, the unamortized portion is recognized in interest income. Loans acquired through a business or asset purchase are reported at fair value, as of acquisition date. Interest income is accrued based upon the daily principal amount outstanding and is then further adjusted by the accretion of any discount or amortization of any premium associated with the loan that was recognized based on the acquisition date fair value using the level-yield method. When a loan is paid off, the unamortized portion is recognized in interest income. A loan is classified as non-accrual generally when it becomes 90 days past due as to interest or principal payments, or sooner if management considers such action to be prudent. All previously accrued but unpaid interest on non-accrual loans is reversed from interest income in the period in which the loan is considered delinquent and the amortization of any unamortized net deferred origination loan fees/costs stops. Interest payments received on non-accrual loans are applied as a reduction of principal. A loan remains on non-accrual status until all principal and interest amounts contractually due are brought current and future payments are reasonably assured. Should a loan transition from non-accrual to accrual, the unrecognized interest earned during the period the loan was on non-accrual and unamortized deferred origination fees and costs are recognized over the remaining contractual life of the loan using the level-yield method.
ALL	ACL on Loans. Upon adoption of ASU 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”), as amended; effective January 1, 2020, using a modified-prospective approach. Upon adoption, the Company recorded a cumulative-effect adjustment of $2.8 million reducing retained earnings, with a corresponding adjustment of $233,000 increasing the ACL on loans, an adjustment of $3.3 million increasing other liabilities for the ACL on off-balance sheet credit exposures, and an adjustment of $769,000 increasing deferred tax assets. The ACL on loans is based on the amortized cost basis of a loan, which is comprised of the unpaid principal balance of the loan, net deferred loan fees (costs), acquired premium (discount), and any write-downs previously taken on the loan. The ACL on loans is increased by charges to provision for credit losses and reduced by charge-offs, net of recoveries. Management evaluates the appropriateness of the ACL on loans quarterly. This evaluation is inherently subjective as it requires material estimates that may be susceptible to significant change from period to period. The ACL on loans is presented on the consolidated statements of condition. Loans past due 30 days or more are considered delinquent. In general, secured loans that are delinquent for 90 consecutive days are placed on non-accrual status and may be subject to individual loss assessment in accordance with established internal policy. In general, unsecured loans that are delinquent for 90 consecutive days are charged-off. In cases where a borrower experiences financial difficulties and the Company makes certain concessionary modifications to contractual terms, the loan is classified as a TDR, with the exception of loan modifications or concessions resulting directly from the effects of the COVID-19 pandemic during 2020 and 2021 that were granted to customers who were otherwise in current payment status at the time of the modification or concession. The ACL on loans reduces the loan portfolio to the net amount expected to be collected, and represents the expected losses over the life of all loans at the reporting date. The allowance incorporates forward-looking information and applies a reversion methodology beyond the reasonable and supportable forecast. The ACL on loans represents the Company's estimated risk of loss within its loan portfolio as of the reporting date. To appropriately measure expected credit losses, management disaggregates the loan portfolio into pools of similar risk characteristics ( i.e. “segments”). The Company utilizes a discounted cash flow approach to calculate the expected loss for each segment. Within the discounted cash flow model, a PD and LGD assumption is applied to calculate the expected loss for each segment. PD is the probability the asset will default within a given timeframe and LGD is the percentage of assets not expected to be collected due to default. The Company's PD and LGD assumptions may be derived from internal historical default and loss experience or from external data where there are not statistically meaningful loss events for a loan segment or it does not have default and loss data that covers a full economic cycle. As of December 31, 2022 and 2021, the primary macroeconomic drivers used within the discounted cash flow model included forecasts of Maine Unemployment, changes in Maine and National GDP, and changes in the Maine Housing Price Index. Management monitors and assesses its macroeconomic drivers at least annually (generally in the fourth quarter) to determine if or that they continue to be the most predictive indicator of losses within the Company’s loan portfolio, and these macroeconomic drivers may change from time to time. To determine its reasonable and supportable forecast, management may leverage macroeconomic forecasts obtained from various reputable sources, which may include, but is not limited to, the Federal Open Market Committee forecast and other publicly available forecasts from well recognized, leading economists or firms. The Company’s reasonable and supportable forecast period generally ranges from one to three years, depending on the facts and circumstances of the current state of the economy, portfolio segment and management’s judgement of what can be reasonably supported. The model reversion period generally ranges from one to six years, and it also depends on the current state of the economy and management’s judgments of such. Management monitors and assesses the forecast and reversion period at least annually. The Company used a one-year forecast and reversion period to calculate the ACL on loans as of December 31, 2022 and 2021. The ACL on loans is calculated over a loan’s contractual life. For term loans, the contractual life is calculated based on the maturity date. For commercial revolving loans with no stated maturity date, the contractual life is calculated based on the internal review date. For all other revolving loans, the contractual life is based on either the estimated maturity date or a default date. The contractual term does not include expected extension, renewals or modifications. The Company's loan portfolio is segmented as follows based on the various risk profiles of the Company's loans: • The commercial loan portfolio is segmented into three categories – (i) commercial real estate, which is collateralized by real estate; (ii) commercial, which is typically utilized for general business purposes; and (iii) SBA PPP loans, which were originated by the Company during the years ended December 31, 2021 and 2020 in response to the COVID-19 pandemic. Commercial real estate is further segmented between non-owner-occupied ( i.e . investment properties) and owner-occupied properties. • Retail loans are a homogenous group, generally consisting of standardized products that are smaller in amount and distributed over a large number of individual borrowers. Retail loans are segmented into three categories – (i) residential real estate, (ii) home equity and (iii) consumer. In calculating the ACL on loans, the contractual life of a loan must be adjusted for prepayments to arrive at expected cash flows. The Company models term loans using an annualized prepayment. When the Company has a specific expectation of differing payment behavior for a given loan, the loan may be evaluated individually. For revolving loans that do not have a principal payment schedule, a curtailment rate is factored into the cash flow. The ACL on loans evaluation may also consider various qualitative factors, such as: (i) actual or expected changes in economic trends and conditions, (ii) changes in the value of underlying collateral for loans, (iii) changes to lending policies, underwriting standards and/or management personnel performing such functions, (iv) delinquency and other credit quality trends, (v) credit risk concentrations, if any, (vi) changes to the nature of the Company's business impacting the loan portfolio, (vii) and other external factors, that may include, but are not limited to, results of internal loan reviews, examinations by bank regulatory agencies, or other such events such as a natural disaster. Certain loans are individually evaluated for estimated credit losses, including those (i) greater than $500,000 that are classified as substandard or doubtful and are on non-accrual, (ii) a TDR, or (iii) that have other unique characteristics differing from the segment. Specific reserves are established when appropriate for such loans based on the present value of expected future cash flows of the loan or the estimated realizable value of the collateral, if any. Management may also adjust its assumptions to account for differences between expected and actual losses from period-to-period. The variability of management’s assumptions could alter the ACL on loans materially and impact future results of operations and financial condition. The loss estimation models and methods used to determine the allowance for credit losses are continually refined and enhanced. Accrued Interest. Accrued interest receivable balances are presented within other assets on the consolidated statements of condition, and excluded from the measurement of the ACL, including investments and loans. Accrued interest receivable is
Goodwill and Core Deposit Intangible Assets	Goodwill and Core Deposit Intangible Assets . Goodwill represents the price paid in an acquisition that is in excess of the fair value of the net assets acquired. Goodwill is not subject to amortization but rather is evaluated at least annually for impairment, or as events and circumstances dictate, at the reporting unit level, and for which the Company has determined it has a single reporting unit. Any impairment is charged to non-interest expense on the consolidated statements of income. The Company evaluates goodwill for impairment annually as of November 30 th , or more frequently as warranted by external and/or internal factors. The Company may utilize a qualitative analysis and/or a quantitative analysis to evaluate goodwill for impairment. The Company has the option to by-pass the qualitative analysis for any given year and perform the quantitative analysis. Using a qualitative analysis to assess goodwill for impairment, the Company will consider various factors to determine if it is more-likely-than-not that its carrying value of its reporting unit exceeds its fair value. These factors include, but are not limited to, the overall macro-economic environment; industry economic and regulatory environment; and company specific factors, including, but not limited to, performance, Company common stock share price, competition and/or significant changes in senior management. Should the Company determine it is more-likely-than-not that the carrying value of its reporting unit exceeds its fair value, then it would then perform the next step of the goodwill impairment test, which is a quantitative analysis. If the Company were to determine it is not more-likely-than-not that the carrying value of its reporting unit exceeds its fair value, the Company would have completed its goodwill impairment evaluation and concluded goodwill was not impaired. After performing the qualitative analysis and determining it is more-likely-than-not that the carrying value of its reporting unit exceeds its fair value or if the Company by-passed the qualitative analysis, it would perform a quantitative analysis to determine if the carrying value of its reporting unit exceeds its fair value. Alternatively, the Company may bypass the qualitative analysis and use a quantitative analysis. In completing the quantitative analysis, the Company may use various valuation techniques such as a discounted cash flow model, a comparative market transaction multiple approach and/or other valuation methods to determine the reporting unit's fair value. Goodwill impairment is recognized the extent the carrying value of a reporting unit exceeds its fair value. The Company completed its testing for impairment of goodwill for the years ended December 31, 2022, 2021 and 2020 and concluded goodwill was not impaired. Refer to Note 4 of the consolidated financial statements for further details. Core deposit intangible assets represents the estimated value of acquired customer relationships and is amortized on a straight-line basis 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. If necessary, management will test the core deposit intangibles for impairment by comparing their carrying value to the expected undiscounted cash flows of the assets. If the undiscounted cash flows of the intangible assets exceed their carrying value then the intangible assets are deemed to be fully recoverable and not impaired. However, if the undiscounted cash flows of the intangible assets are less than their carrying value then management must compare the fair value of the intangible assets to its carrying value. If the fair value of the intangible assets exceeds their carrying value then the intangible assets are not impaired. If the fair value of the intangible assets is less than its carrying value, then an impairment charge is recorded to mark the carrying value of the intangible assets to fair value. For the years ended December 31, 2022, 2021 and 2020, there were no events or changes in circumstances that indicated the carrying amount may not be recoverable.
BOLI	BOLI . BOLI represents the cash surrender value of life insurance policies on the lives of certain active and retired employees where the Company is the beneficiary and is recorded as an asset on the consolidated statements of condition. Increases in the cash surrender values of the policies, as well as death benefits received, net of any cash surrender value, are recorded in non-interest income on the consolidated statements of income, and are not subject to income taxes. The Company reviews the financial strength of the insurance carriers prior to the purchase of life insurance policies and no less than annually thereafter. A life insurance policy with any individual carrier is limited to 10% of Tier 1 capital (as defined for regulatory purposes) and the total cash surrender value of life insurance policies is limited to 25% of Tier 1 capital.
Premises and Equipment	Premises and Equipment . Premises and equipment purchased in normal course are stated at cost less accumulated depreciation, while premises and equipment obtained through the acquisition of a company or branch acquisition are stated at their estimated fair values as of the acquisition date less accumulated depreciation that occurred subsequent to the acquisition date. Depreciation and amortization are computed using the straight-line method over the estimated useful lives of the related assets. Leasehold improvements are amortized over the lesser of the term of the respective lease or the estimated life of the improvement. Land is carried at cost. Repairs and maintenance costs that are not an improvement or do not extend the estimated useful life of the asset are expensed as incurred. Software costs, including cloud-based software licenses that qualify as internal-use software, are stated at cost less accumulated amortization within other assets on the consolidated statements of condition. Amortization expense is calculated using the straight-line method over the estimated useful lives of the related assets. Cloud-based software costs that do not qualify as internal-use software are capitalized as service contracts within other assets on the consolidated statements of condition and expensed ratably over the term of the contract period. Long-lived assets, including premises and equipment and certain identifiable intangibles, are reviewed for impairment whenever events or changes in circumstances indicate the carrying amount of an asset may not be recoverable. The amount of the impairment loss, if any, is based on the asset’s fair value. No impairment losses were recognized in 2022, 2021, or 2020. Leases. The Company leases office space, space for ATM locations and certain branch locations under noncancellable operating leases, several of which have renewal options to extend lease terms. Upon commencement of a new lease, the Company will recognize a ROU asset and corresponding lease liability. The Company makes the decision on whether to renew an option to extend a lease by considering various factors. The Company will recognize an adjustment to ROU asset and lease liability when lease agreements are amended and executed. The discount rate used in determining the present value of lease payments is based on the lessor’s implicit rate in the lease if known or on the Company's incremental borrowing rate for borrowing terms similar to each lease at commencement date. The Company has lease agreements with lease and non-lease components, which are generally accounted for separately. For real estate leases, non-lease components and other non-components, such as common area maintenance charges, real estate taxes and insurance, are not included in the measurement of the lease liability since they are generally able to be segregated. The Company has elected the short-term lease recognition exemption for all leases that qualify.
OREO	OREO . OREO properties acquired through foreclosure or deed-in-lieu of foreclosure are recorded initially at estimated fair value less estimated costs to sell. Any write-down of the recorded investment in the related loan is charged to the ACL on loans 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. Any subsequent declines in the fair value of a property are recorded as a valuation allowance on the asset. Any subsequent increases in the fair value of a property are recorded as reductions of the valuation allowance, but not below zero. At December 31, 2022 and 2021, OREO properties were carried within other assets on the consolidated statements of condition at $0 and $165,000, respectively. Upon a sale of an OREO property, any excess of the carrying value over the sale proceeds is recognized as a loss on sale. Any excess of sale proceeds over the carrying value of the OREO property is first applied as a recovery to the valuation allowance, if any, with the remainder being recognized as a gain on sale. The recognized gain or loss upon sale of OREO property is recognized within other real estate owned and collection costs, net on the consolidated statements of income. Operating expenses, including legal and other direct expenses, and changes in the valuation allowance relating to foreclosed assets are included in other real estate owned and collection costs, net on the consolidated statements of income.
Mortgage Banking	Mortgage Banking . Residential real estate mortgage loans are originated for purposes of being (i) held for investment and (ii) held for sale into the secondary market. The transfer of these financial assets is accounted for as a sale when control over the asset has been surrendered. Control is deemed to be surrendered when (i) the asset has been isolated from the Company, (ii) the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred asset, and (iii) the Company does not maintain effective control over the transferred asset through an agreement to repurchase it before its maturity. The Company records the gain on sale of the financial asset within mortgage banking income, net on the consolidated statements of income, net of direct and indirect costs incurred to originate the loan. Servicing assets are recognized as separate assets when servicing rights are acquired through the sale of residential mortgage loans with servicing rights retained. Capitalized servicing rights are initially recorded at fair value and reported within other assets on the consolidated statements of condition and recognized as income within mortgage banking income, net on the consolidated statements of income. Servicing rights are amortized in proportion to, and over the period of, the estimated future servicing of the underlying mortgages (typically, the contractual life of the mortgage). The amortization of mortgage servicing rights is recorded as a reduction of income within non-interest income on the consolidated statements of income.
Short-Term and Long-Term Borrowings	Short-Term and Long-Term Borrowings. Short-term borrowings are those that upon origination are scheduled to mature within one year. The Company's short-term borrowings may include, but are not limited to, FHLBB overnight and FHLBB advances, customer repurchase agreements, federal funds purchased, and line of credit advances. Long-term borrowings are those that upon origination are scheduled to mature in one or more years. The Company's long-term borrowings may include, but are not limited to, FHLBB advances, subordinated debentures, and wholesale repurchase agreements. Short-term and long-term borrowings on the consolidated statements of income are presented net of unamortized issuance costs, if any, and amortized over the life of the borrowing. The Company is required to post collateral for certain borrowings, for which it generally posts loans and/or investment securities as collateral.
Income Taxes	Income Taxes . Income taxes are accounted for using the asset and liability method. Under this method, deferred tax assets and liabilities are recognized for the future tax implications attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. If current information suggests that it is not more-likely than-not that the Company will not be able to realize the deferred tax assets, a valuation allowance is established. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. The Company assesses quarterly whether or not a valuation allowance on its deferred tax assets is necessary. If it is more- likely-than-not that the Company will not be able to realize the benefit of the deferred tax assets, then a valuation allowance is established on the deferred tax asset not expected to be realized. At December 31, 2022 and 2021, the Company did not carry a valuation allowance on its deferred tax assets. The Company accounts for its windfall tax benefits and shortfalls within income tax expense on the consolidated statements of income as a discrete period item in the period generated.
EPS	EPS . Basic EPS excludes dilution and is computed by dividing net income applicable to common stock by the weighted-average number of common shares outstanding for the period. Diluted EPS reflects the potential dilution that could occur if certain securities or other contracts to issue common stock (such as stock options) were exercised or converted into additional common shares that would then share in the earnings of the Company. Diluted EPS is computed by dividing net income applicable to common stock by the weighted-average number of common shares outstanding for the period, plus an incremental number of common-equivalent shares computed using the treasury stock method. Unvested share-based payment awards which include the right to receive non-forfeitable dividends are considered to participate with common stock in undistributed earnings for purposes of computing EPS. Restricted share grants and management stock purchase grants awarded under the 2012 Equity and Incentive Plan, are considered participating securities for this purpose. Accordingly, the Company is required to calculate basic and diluted EPS using the two-class method. The calculation of EPS using the two-class method (i) excludes any dividends paid or owed on participating securities and any undistributed earnings considered to be attributable to participating securities from the numerator and (ii) excludes the dilutive impact of the participating securities from the denominator.
Postretirement Plans	Postretirement Plans . The Company sponsors various retirement plans for current and former employees, including a SERP for certain officers of the Company and a postretirement health care and life insurance plan to certain eligible retired employees. The SERP and postretirement benefit plans are unfunded and have no plan assets, and the Company has recorded a liability on the consolidated statements of condition. For the SERP, benefit obligations are estimated using the projected unit credit method. Under this method, each participant's benefits are attributed to years of service, taking into consideration future salary increases and the SERP's benefit allocation formula. Thus, the estimated total pension to which each participant is expected to become entitled to at retirement is broken down into units, each associated with a year of past or future credited service. For the SERP, an individual's estimated attributed benefit for valuation purposes related to a particular separation date is the benefit described under the SERP based on credited service as of the measurement date, but determined using the projected salary that would be used in the calculation estimate of the benefit on the expected separation date. The Company has obligations with various active and retired employees related to certain postretirement benefits. The obligations are based on the employee's date of hire and years of service through retirement, with the associated cost recognized over the requisite service period. Under the plan, the postretirement benefit amount the Company will pay for any given year for an individual is capped. The accrual methodology results in an accrued amount at the full eligibility date equal to the then present value of all of the future benefits expected to be paid. Net periodic benefits cost (credit) includes service costs and interest costs based on the assumed discount rate, amortization of prior service costs due to plan amendments and/or amortization of actuarial gains or losses. As prior service costs and actuarial gains or losses are amortized, they are reclassified from AOCI on the consolidated statements of condition into other expenses on the consolidated statements of income. The amortization of actuarial gains and losses is determined using the 10% corridor minimum amortization approach and is taken over the average remaining future working lifetime of the plan participants.
Revenue from Contracts with Customers	Revenue from Contracts with Customers. The Company receives a portion of its non-interest income from contracts with customers, which is accounted for in accordance with ASC 606. 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 in recording revenues from contracts with customers in accordance with ASC 606.
Stock-Based Compensation	Stock-Based Compensation .
Off-Balance Sheet Credit Related Financial Instruments	Off-Balance Sheet Credit Exposures . In the ordinary course of business, the Company enters into commitments to extend credit, including commercial letters of credit and standby letters of credit. Such financial instruments are recorded as loans when they are funded. ACL on Off-Balance Sheet Credit Exposures. The ACL on off-balance sheet credit exposures, excluding those that are unconditionally cancellable by the Company, estimates the expected losses on the unfunded commitments and standby letters of credit at each reporting date. To appropriately measure expected credit losses, management disaggregates the loan portfolio into similar risk characteristics, identical to those determined for the loan portfolio. An estimated funding rate is then applied to the qualifying unfunded loan commitments and standby letters of credit using the Company’s own historical experience to estimate the expected funded for each loan segment as of the reporting date. Once the expected funded amount for each loan segment is determined, the loss rate, which is the calculated expected loan loss as a percent of the amortized cost basis for each loan segment, is applied to calculate the ACL on off-balance sheet credit exposures as of the reporting date. The ACL on off-balance sheet credit exposures is presented within accrued interest and other liabilities on the consolidated statements of condition. A charge (credit) to provision for credit losses on the consolidated statements of income is made to account for the change in the ACL on off-balance sheet exposures between reporting periods.
Derivative Financial Instruments Designated as Hedges	Derivative Financial Instruments Designated as Hedges . The Company records all derivatives on the balance sheet 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
Segment Reporting	Segment Reporting . Operating segments are the components of an entity for which separate financial information is available and evaluated regularly by the chief operating decision-maker in order to allocate resources and assess performance. The Company's chief operating decision-maker assesses consolidated financial results to make operating and strategic decisions, assess performance, and allocate resources. Therefore, the Company has determined that its business is conducted in one reportable segment and represents the consolidated financial statements of the Company.
Recent Accounting Pronouncements	Recent Accounting Pronouncements: The following provides a brief description of recently issued accounting pronouncements that have been adopted by the Company subsequent to December 31, 2022: 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 write-offs for entities that have adopted ASU 2016-13. ASU 2022-02 is effective for fiscal years beginning after December 15, 2022, with early adoption permitted. The Company has evaluated the effect of ASU 2022-02 on its consolidated financial statements and adopted effective January 1, 2023. ASU 2022-02 does not have a material impact to the Company’s consolidated financial statements. 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 amendment is effective for fiscal years beginning after December 15, 2022. The Company adopted ASU 2022-01, as amended, effective January 1, 2023 and has leveraged the “portfolio layer” method to enter into interest rate swaps to hedge fixed-rate residential mortgages during the first quarter of 2023.
