General Business. 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. as of and for the year ended December 31, 2020, 2019 and 2018, and HPFC, Property A, Inc. and Property P, Inc. as of and for the year ended December 31, 2019 and 2018). 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, including the ACL, including the allowance for loan losses, off-balance sheet credit exposures, and AFS and HTM debt securities (effective for periods on or after January 1, 2020, upon adoption of ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326): M easurement of Credit Losses on Financial Instruments ("ASU 2016-13"), as amended), the accounting for business combinations including subsequent impairment analyses for goodwill and other intangible assets, accounting for income taxes, postretirement benefits, and asset impairment assessments, including the assessment of OTTI of investment securities (for periods prior to January 1, 2020). Subsequent Events. The Company has evaluated events and transactions subsequent to December 31, 2020 for potential recognition or disclosure as required by GAAP. 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. Cash, Cash Equivalents and Restricted Cash. For the purposes of reporting, cash and cash equivalents consist of cash on hand and amounts due from banks. During the first quarter of 2020, the Company was required by the FRB to maintain cash reserves equal to a percentage of deposits. In response to the COVID-19 pandemic, in March 2020, the FRB reduced reserve requirement ratios to 0%, effectively eliminating cash reserve requirements for the reserve maintenance period beginning March 26, 2020. 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. Effective January 1, 2018, the Company adopted ASU No. 2016-01, Income Statement - Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Liabilities ("ASU 2016-01"), and recorded a cumulative-effect adjustment of $198,000 to reclassify the unrealized gain, net of tax, on the Company's equity securities with a readily determinable fair value as of January 1, 2018, previously designated as AFS, from AOCI to retained earnings. 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 (effective January 1, 2020). Upon adoption of ASU 2016-13, effective January 1, 2020, but has been applied to reporting periods on or after October 1, 2020, management now 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 OCI. 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, 2020 and January 1, 2020 (i.e. ASU 2016-13 adoption), there was no allowance carried on the Company's AFS debt securities. Refer to Note 2 of the consolidated financial statements for further discussion. ACL on (or Write-off of) HTM Debt Securities (effective January 1, 2020). The Company adopted ASU 2016-13, which is commonly referred to as "CECL" (i.e. current expected credit losses), effective January 1, 2020, but has been applied to reporting periods on or after October 1, 2020. ASU 2016-13 requires companies to estimate 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. Given the rarity of municipal defaults and losses, the Company will utilize external third party loss forecast models as the sole source of municipal 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, 2020 and January 1, 2020, there was no allowance carried on the Company’s HTM debt securities. Refer to Note 2 of the consolidated financial statements for further discussion. OTII Assessment (periods prior to January 1, 2020). For periods p rior to the adoption of ASU No. 2016-13, effective January 1, 2020, management conducted a quarterly review and evaluation of its AFS and HTM debt investments to determine if the decline in fair value of any security appeared to be other-than-temporary. The factors considered included, but were not limited to: the length of time and the extent to which the fair value has been less than cost, the financial condition and near-term prospects of the issuer, the credit ratings of the security or issuer, whether the decline in fair value appears to be issuer specific or, alternatively, a reflection of general market or industry conditions, and the Company’s intent and ability to hold the security for a period of time sufficient to allow for a recovery in fair value. For its AFS and HTM debt investments that it did not intend to sell and was not more-likely-than-not required to sell before recovery of its amortized cost basis, the other-than-temporary decline in the fair value of the debt security related to: (i) credit loss was recognized in non-interest income on the consolidated statements of income; and (ii) other factors was recognized in AOCI, net of tax. Debt securities it intended to sell or was more-likely-than-not required to sell before recovery of amortized cost, an OTTI was recorded equal to the entire difference between the debt investment's amortized cost basis and its fair value within non-interest income on the consolidated statements of income. 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 outside the scope of ASU 2016-01, 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, typically, 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. Originated Loans 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. For originated loans, interest income is accrued based upon the daily principal amount outstanding except for loans on non-accrual status. As of acquisition date, each acquired loan is reported at fair value. For acquired loans, 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. For originated loans, 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. 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, including impaired 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 status back to accrual status, the unrecognized interest earned during the period the loan was on non-accrual status 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. On March 27, 2020, the CARES Act was signed into law in response to COVID-19. Under Section 4014 of the CARES Act, the Company was permitted to delay its compliance with ASU 2016-13, commonly referred to as "CECL," until the earlier of (1) the date on which the national emergency concerning the COVID-19 pandemic that the President of the United States declared on March 15, 2020 terminated, or (2) December 31, 2020. The Company delayed its compliance with CECL as permitted under the CARES Act and adopted CECL on December 31, 2020, effective January 1, 2020, but applied to reporting periods on or after October 1, 2020 using a modified-prospective approach. As a result, the allowance for credit losses for annual and interim periods before October 1, 2020 continue to be reported under prior accounting guidance, commonly referred to as the "incurred loss model." Upon adoption, a cumulative-effect adjustment of $2.8 million was recorded 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 calculation under CECL and the incurred loss methodology 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, under CECL, may be subject to individual loss assessment in accordance with established internal policy. Under the incurred loss model, these loans were subject to impairment and/or 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 those loans deferred and/or modified in accordance with the provisions of the CARES Act or regulatory guidance in response to COVID-19. Modifications may include adjustments to interest rates, extensions of maturity, and other actions intended to minimize economic loss and avoid foreclosure or repossession of collateral. An allowance is established on a loan classified as a TDR if the present value of expected future cash flows (or, alternatively, the observable market price of the loan or the fair value of the collateral if the loan is collateral-dependent) is less than the recorded investment of the loan. Non-accrual loans that are restructured as TDRs remain on non-accrual status for a period of at least six months to demonstrate that the borrower can meet the restructured terms. If the restructured loan is on accrual status prior to being modified, it is reviewed to determine if the modified loan should remain on accrual status. If the borrower’s ability to meet the revised payment schedule is not reasonably assured, the loan is classified as a non-accrual loan. Loans classified as TDRs remain classified as such for the life of the loan, except in limited circumstances, when it is determined that the borrower is performing under the modified terms and the restructuring agreement specified an interest rate greater than or equal to an acceptable market rate for a comparable new loan at the time of the restructuring. In response to COVID-19, the Company worked with businesses and consumers to provide temporary debt payment relief that generally provided principal and/or interest payment deferrals for a period of 180 days or less. For loans temporarily modified due to COVID-19, under the CARES Act and regulatory guidance, the Company applied the following accounting treatment in this order: 1.The Company may account for a loan modification in accordance with Section 4013 of the CARES Act if the loan modification (i) meets the criteria set forth in Section 4013 of the CARES Act and (ii) the Company elects to apply Section 4013 of the CARES Act. Section 4013 of the CARES Act suspended TDR designation for loan modifications related to the COVID-19 pandemic. In order for the loan modification to qualify under Section 4013 of the CARES Act, the loan must not have been more than 30 days past due as of December 31, 2019. This guidance is applicable for loan modifications beginning on March 1, 2020 and ending on the earlier of (i) December 31, 2020, or (ii) the date that is 60 days after the date the national emergency concerning the COVID-19 pandemic declared by the President on March 13, 2020 under the National Emergencies Act terminates. 2.Should a loan modification (i) not meet the criteria set forth in Section 4013 of the CARES Act or (ii) the Company elects to not apply Section 4013 of the CARES Act, but the loan modification (a) meets the criteria provided in the "Interagency Statement on Loan Modifications and Reporting for Financial Institutions Working with Customers Affected by the Coronavirus (Revised)," issued by the banking agencies on April 7, 2020, and (b) the Company elects to apply this guidance, then the Company may account for the loan modification in accordance with the interagency guidance. Under this guidance, if the loan was no more than 30 days past due at the time the loan modification program was implemented, the modification was short-term in duration (generally, less than six months), and the modification was related to COVID-19, then it may be presumed that the borrower is not experiencing financial difficulty, and, therefore, that the modification does not qualify as a TDR. 3.Should a loan modification (i) not meet the criteria set forth in Section 4013 of the CARES Act or the interagency guidance described above, or (ii) the Company elects not to apply the guidance, then the Company would assess the loan modification under its existing accounting policies. In December 2020, the President signed the Consolidated Appropriations Act of 2021 into law, which provided additional relief to consumers and businesses impacted by COVID-19. The act extended the provisions within the CARES Act that provided TDR accounting relief to the earlier of: (i) December 31, 2021 or (ii) the date that is 60 days after the date the national emergency concerning the COVID-19 pandemic declared by the President on March 13, 2020 under the National Emergencies Act terminates. Under CECL, 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 reflects the risk of loss on the loan portfolio. To appropriately measure expected credit losses, management disaggregates the loan portfolio into pools of similar risk characteristics. The Company utilizes a discounted cash flow approach to calculate the expected loss for each segment. Within the discounted cash flow model, a probability of default (“PD”) and loss given default (“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 the assets not expected to be collected due to default. PD and LGD data are derived from internal historical default and loss experience as well as the use of external data where there are not statistically meaningful loss events for a loan segment. The primary macroeconomic drivers used within the discounted cash flow model include forecasts of Maine Unemployment, changes in Maine and National GDP, as well as changes in Maine Retail Trade and Housing Price Index. Management will monitor and assess its macroeconomic drivers at least annually 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 the Federal Open Market Committee forecast and/or 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. 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. Upon adoption of CECL, effective January 1, 2020, but applied to reporting periods on or after October 1, 2020, the loan portfolio has been segmented as follows based on the various risk profiles of the Company's loans: •The commercial loan portfolio has been segmented between (i) commercial real estate, which is collateralized by real estate, and (ii) commercial, which is typically utilized for general business purposes. 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. The group is segmented into three categories – residential real estate, home equity and consumer. Contractual terms 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 also considers 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 tested individually 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 troubled debt restructuring or (iii) that have unique characteristics. 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 level of the allowance for credit losses and may have a material impact on 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. Incurred Loss Methodology. For annual and interim reporting periods prior to October 1, 2020, the Company estimated the allowance for loan losses using the incurred loss methodology. In determining the appropriate allowance, the Company used a methodology to systematically measure the amount of estimated loan loss exposure inherent in the loan portfolio. The methodology included three elements: (1) identification of loss allocations for certain specific loans, (2) loss allocation factors for certain loan types based on credit risk and loss experience, and (3) general loss allocations for other qualitative and economic factors. The allocations for specific loans were determined based on loans that have a principal balance of $500,000 or more that were classified as substandard or doubtful and were on non-accrual status. Such loans were classified as impaired and an allowance was established when the discounted expected future cash flows (or collateral value or observable market price) of the impaired loan was lower than the recorded investment of that loan. Loans that did not meet the above criteria were separated into risk pools by portfolio segment and risk ratings. The Company would then evaluate each risk pool collectively for impairment through loss allocation factors. The Company uses a risk rating system for certain loan segments to determine the credit quality of these loan pools and applied the related loss allocation factors. In assessing the risk rating of a particular loan, the Company considers, among other factors, the obligor’s debt capacity, financial condition, the level of the obligor’s earnings, the amount and sources of repayment, the performance with respect to loan terms, the adequacy of collateral, the level and nature of contingent liabilities, management strength, and the industry in which the obligor operates. These factors are based on an evaluation of historical information, as well as subjective assessment and interpretation of current conditions. Emphasizing one factor over another, or considering additional factors that may be relevant in determining the risk rating of a particular loan but which are not an explicit part of the Company's methodology, could impact the risk rating assigned to that loan. The Company would at least annually, and more frequently as deemed prudent by management, reassess and revise the loss allocation factors used in the assignment of loss exposure to appropriately reflect the analysis of loss experience. Portfolios of more homogeneous populations of loans including home equity and consumer loans are analyzed as groups taking into account delinquency rates and other economic conditions that may affect the ability of borrowers to meet debt service requirements, including interest rates and energy costs. The Company also considers regulatory guidance, historical loss ranges, portfolio composition, and other changes in the portfolio. An additional allocation is determined based on a judgmental process whereby management considers qualitative and quantitative assessments of other environmental factors. Accrued Interest. Upon adoption of CECL, effective as of January 1, 2020, the Company made the following elections regarding accrued interest receivable: (i) present accrued interest receivable balances within other assets on the consolidated statements of condition; (ii) exclude accrued interest from the measurement of the allowance for credit losses, including investments and loans; and (iii) continue to write-off accrued interest receivable by reversing interest income. The Company has a robust policy in place to write-off accrued interest when a loan is placed on non-accrual. Accrued interest is written-off by reversing previously recorded interest income. For loans, write-off typically occurs when a loan has been in default for 90 days or more. Accrued interest on non-accrual loans was written off during the year ended December 31, 2020, by reversing interest income. Historically, the Company has not experienced uncollectible accrued interest receivable on investment debt securities. Goodwill and Core Deposit Intangible Assets. Goodwill represents the excess cost of an acquisition over 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. 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. Effective January 1, 2020, the Company adopted ASU No. 2017-04, Intangibles - Goodwill and Other (TOPIC 350): Simplifying the Test for Goodwill Impairment ("ASU 2017-04"), and accordingly will now recognize an impairment of goodwill to the extent the carrying value of a reporting unit exceeds its fair value. ASU 2017-04 eliminated the need to calculate the implied fair value of goodwill for a reporting unit and recognize an impairment to the extent the carrying value of goodwill exceeded its implied fair value. ASU 2017-04 was applied prospectively as of the effective date. For periods prior to adoption of ASU 2017-04, if the reporting unit's fair value exceeded its carrying value, then goodwill was not impaired and no further assessment was required. However, if the reporting unit's fair value was less than its carrying value, then it was required to derive an implied fair value of goodwill for the reporting unit. If the reporting unit's implied fair value of goodwill exceeded its carrying value, then goodwill was not impaired. However, if the reporting unit's implied fair value of goodwill was less than its carrying value, an impairment charge was recorded to reduce goodwill to its calculated implied fair value. The Company completed its testing for impairment of goodwill for the year ended December 31, 2020, 2019 and 2018 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 year ended December 31, 2020, 2019 or 2018, 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 15% 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. 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, 2020 and 2019, OREO properties were carried within other assets on the consolidated statements of condition at $236,000 and $94,000, 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. 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. Servicing assets are evaluated for impairment quarterly based upon the fair value of the rights as compared to amortized cost. Impairment is determined by stratifying rights by predominant characteristics, such as interest rates and terms. Fair value is determined using prices for similar assets with similar characteristics, when available, or based upon discounted cash flows using market-based assumptions. Impairment of the servicing assets is recognized through a valuation allowance to the extent that fair value is less than the capitalized amount. If it is later determined that all or a portion of the impairment no longer exists, a reduction of the allowance may be recorded increasing income, but not below zero. Servicing fee income is recorded for fees earned for servicing loans for investors. The fees are based on a contractual percentage of the outstanding principal or a fixed amount per loan and are recorded as income within non-interest income on the consolidated statements of income when earned. 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. 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 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, 2020 and 2019, 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. 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 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. 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. Furthermore, the Company's obligation exists until the participant qualifies for Medicare. 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. The Company receives a portion of its non-interest income from contracts with customers, which is accounted for in accordance with ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) ("ASC 606"). Refer to Note 16 of the consolidated financial statements for further details. Stock-Based Compensation. The fair value of restricted stock awards, restricted stock units and stock options is determined on the grant date. For restricted stock awards and units, compensation is recognized ratably over the requisite service period equal to the fair value of the award. For stock option awards, the fair value is determined using the Black-Scholes option-pricing model. Compensation expense for stock option awards is recognized ratably over the requisite service period equal to the fair value of the award. For performance-based share awards, the Company estimates the degree to which performance conditions will be met to determine the number of shares that will vest and the related compensation expense. Compensation expense is adjusted in the period such estimates change. The Company does not assume an estimated forfeiture rate on its nonvested share-based awards in its reporting of share-based compensation expense. Should a share-based award be forfeited, the Company would reverse all associated compensation expense previously recorded on the nonvested shares. 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 Company established an ACL on off-balance sheet credit exposures by recording a liability for expected credit losses on certain unfunded loan commitments and standby letters of credit. Prior to the adoption of CECL, effective January 1, 2020, but has been applied to reporting periods on or after October 1, 2020, the ACL on off-balance sheet credit exposures represented management's best estimate of probable inherent losses on unfunded loan commitments and standby letters of credit. Upon adoption of CECL, 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 CECL 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. Refer to Note 11 of the consolidated financial statements for further details as of each reporting period. Derivative Financial Instruments Designated as Hedges. The Company recognizes all derivatives in the consolidated statements of condition at fair value. On the date the Company enters into the derivative contract, the Company designates the derivative as a hedge of either a forecasted transaction or the variability of cash flows to be received or paid related to a recognized asset or liability (“cash flow hedge”), a hedge of the fair value of a recognized asset or liability or of an unrecognized firm commitment (“fair value hedge”), or a held for trading instrument (“trading instrument”). The Company formally documents relationships between hedging instruments and hedged items, as well as its risk management objectives and strategy for undertaking various hedge transactions. The Company also assesses, both at the hedge’s inception and on an ongoing basis, whether the derivatives that are used in hedging transactions are effective in offsetting changes in cash flows or fair values of hedged items. Changes in fair value of a derivative that is effective and that qualifies as a cash flow hedge are recorded in OCI and are reclassified into earnings when the forecasted transaction or related cash flows affect earnings. Changes in fair value of a derivative that qualifies as a fair value hedge and the change in fair value of the hedged item are both recorded in earnings and offset each other when the transaction is effective. Those derivatives that are classified as trading instruments are recorded at fair value with changes in fair value recorded in earnings. The Company discontinues hedge accounting when it determines that the derivative is no longer effective in offsetting changes in the cash flows of the hedged item, that it is unlikely that the forecasted transaction will occur, or that the designation of the derivative as a hedging instrument is no longer appropriate. The Company adopted ASU 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities ("ASU 2017-12") in the fourth quarter of 2018. ASU 2017-12 required the Company to apply the requirements to existing hedging relationships on the date of adoption, and the effect of the adoption on retained earnings was reflected as of January 1, 2018. The guidance did not have an impact on the Company's derivatives that qualified as hedges on the date of adoption, and, thus, no adjustment was made to beginning retained earnings. In conjunction with the adoption of ASU 2017-12, the Company made the transition election to reclassify $92.0 million in book value of securities from HTM to AFS that qualified. 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 Adopted: ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326): M easurement of Credit Losses on Financial Instruments ("ASU 2016-13"), updated by ASU No. 2018-19 - Financial Instruments - Credit Losses (Topic 326): Codification improvements to Topic 326 ("ASU 2018-19"), ASU No. 2019-04, Codification Improvements to Topic 326 ("ASU 2019-04"), ASU No. 2019-05, Financial Instruments - Credit Losses (Topic 326): Targeted Transition Relief ("ASU 2019-05") and ASU No. 2019-11, Codification Improvements to Topic 326 ("ASU 2019-11"). The FASB issued ASU 2016-13 to require more timely recording of credit losses on loans and other financial instruments held by financial institutions and other organizations. The Company adopted ASU 2016-13 and the related updates to the standard on December 31, 2020, effective January 1, 2020, but applied to reporting periods on or after October 1, 2020. Refer to the aforementioned sections Investments, ACL on Loans, Accrued Interest and ACL on Off-Balance Sheet Credit Exposures for further details surrounding the adoption of ASU 2016-13 and its related updates. ASU No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes ("ASU 2019-12"). The FASB issued ASU 2019-12 to simplify the accounting for income taxes by removing certain technical exceptions and by clarifying and amending certain areas. ASU 2019-12 is effective for interim and annual periods beginning after December 15, 2020, and as such the Company adopted effective January 1, 2021. The Company does not expect the adoption of ASU 2019-12 to have a material impact on its consolidated financial statements. Recent Accounting Pronouncements Issued but not yet Adopted: ASU No. 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform ("ASU 2020-04"), updated by ASU No. 2021-01, Reference Rate Reform (Topic 848) Scope ("ASU 2021-01"). The FASB issued ASU 2020-04 to ease the potential burden in accounting for recognizing the effects of reference rate reform on financial reporting. The ASU provides optional expedients and exceptions for applying GAAP to contracts, hedging relationships, and other transactions that are affected by reference rate reform, if certain criteria are met. The amendments in this update apply only to contracts, hedging relationships, and other transactions that reference LIBOR or another reference rate expected to be discontinued due to reference rate reform. ASU 2021-01 was subsequently issued to clarify that certain optional expedients and exceptions in Topic 848 for contract modifications and hedge accounting apply to derivatives that are affected by the discounting transition. ASU 2020-04 and ASU 2020-01 are effective as of March 12, 2020 through December 31, 2022, with adoption permitted prospectively from a date within an interim period that includes or is subsequent to March 12, 2020. Once elected, the amendments must be applied prospectively for all eligible contract modifications. The Company, which has not yet adopted the amendments in these updates, has assembled a cross-functional project team that is currently reviewing contracts and existing processes in order to assess the risks and potential impact to the Company of the transition away from LIBOR to a new reference rate.
