FORWARD-LOOKING STATEMENTS

The discussions set forth below and in the documents we incorporate by reference herein contain certain statements that may be considered forward-looking statements under the Private Securities Litigation Reform Act of 1995, including certain plans, exceptions, goals, projections, and statements, which are subject to numerous risks, assumptions, and uncertainties. Forward-looking statements can be identified by the use of the words “believe,” “expect,” “anticipate,” “intend,” “estimate,” “assume,” “plan,” “target,” or “goal” or future or conditional verbs such as “will,” “may,” “might,” “should,” “could” and other expressions which predict or indicate future events or trends and which do not relate to historical matters. Forward-looking statements should not be relied on, because they involve known and unknown risks, uncertainties and other factors, some of which are beyond the control of Camden National Corporation (the "Company"). These risks, uncertainties and other factors may cause the actual results, performance or achievements of the Company to be materially different from the anticipated future results, performance or achievements expressed or implied by the forward-looking statements.

The following factors, among others, could cause the Company’s financial performance to differ materially from the Company’s goals, plans, objectives, intentions, expectations and other forward-looking statements:

• weakness in the United States economy in general and the regional and local economies within the New England region and Maine, which could result in a deterioration of credit quality, an increase in the allowance for loan losses or a reduced demand for the Company’s credit or fee-based products and services;

• changes in trade, monetary, and fiscal policies and laws, including interest rate policies of the Board of Governors of the Federal Reserve System;

• inflation, interest rate, market, and monetary fluctuations;

• competitive pressures, including continued industry consolidation and the increased financial services provided by non-banks;

• volatility in the securities markets that could adversely affect the value or credit quality of the Company’s assets, impairment of goodwill, or the availability and terms of funding necessary to meet the Company’s liquidity needs, and that could lead to impairment in the value of securities in the Company's investment portfolio;

• changes in information technology that require increased capital spending;

• changes in consumer spending and savings habits;

• changes in tax, banking, securities and insurance laws and regulations; and

• changes in accounting policies, practices and standards, as may be adopted by the regulatory agencies as well as the Financial Accounting Standards Board ("FASB"), and other accounting standard setters.

You should carefully review all of these factors, and be aware that there may be other factors that could cause the Company's actual results to differ materially from those anticipated, including the risk factors listed in Part I, Item 1A, “Risk Factors,” beginning on page 12. Readers should carefully review the risk factors described therein and should not place undue reliance on our forward-looking statements.

These forward-looking statements were based on information, plans and estimates at the date of this report, and we do not promise to update any forward-looking statements for any reason, including to reflect changes in underlying assumptions or factors, new information, future events or other changes.

PART I

Item 1. Business

Overview. Camden National Corporation (hereafter referred to as “we,” “our,” “us,” or the “Company”) is a publicly-held bank holding company, with $4.4 billion in assets at December 31, 2019, incorporated under the laws of the State of Maine and headquartered in Camden, Maine. Camden National Bank (the "Bank"), a wholly-owned subsidiary of the Company, was founded in 1875. The Company was founded in 1984, went public in 1997 and is now registered with NASDAQ Global Market (“NASDAQ”) under the ticker symbol "CAC."

Our consolidated financial statements accompanying this Form 10-K include the accounts of the Company, the Bank and its subsidiaries and divisions. All inter-company accounts and transactions have been eliminated in consolidation.

Who We Are. Since our founding, we have been a values-guided, community-oriented bank that is dedicated to our customers, employees, communities and shareholders.

We are a trusted corporate partner who cares for our neighbors and employees, and we strive to follow responsible business practices under transparent, ethical governance. Our commitment to enhancing environmental, social and governance practices reinforces our focus on building a strong corporate culture across our company. Several characteristics define our culture and approach:

• We are a values-based, socially-responsible organization

• We are committed to our Vision to “Deliver your best banking experience”

• We demonstrate dedication to our four core constituents: customers, employees, communities, and shareholders

Everything we do, both in the office and in the community, is guided and inspired by our Core Values:

• Honesty and integrity - above all else

• Trust - built on fairness

• Service - second to none

• Responsibility - to use our resources for the greater good

• Excellence - through hard work and lifelong learning

Our culture and values are strengths that support our strategic goal to generate consistent, sustainable long-term value for all our constituents.

What We Do. The Company, as a diversified financial services provider, pursues the objective of achieving long-term sustainable growth by balancing growth opportunities against profit, while mitigating risks inherent in the financial services industry. The primary business of the Company and the Bank is to attract deposits from, and to extend loans to, consumer, institutional, municipal, non-profit and commercial customers. The Company, through the Bank, provides a broad array of banking and other financial services, including wealth management and trust services, brokerage, investment advisory and insurance services, to consumer, business, non-profit and municipal customers. For the year ended December 31, 2019, 2018 and 2017, net interest income was our primary revenue source, representing 75%, 76%, and 75%, respectively, of our total revenues (sum of net interest income and non-interest income). Net interest income is the interest earned on our lending activities, investment securities and other interest-earning assets, less the interest paid on interest-bearing deposits and borrowings.

We have achieved a five-year compounded annual asset growth rate of 10%, resulting in $4.4 billion in total assets at December 31, 2019. Asset growth over the past five years of $1.6 billion has come by way of acquisition and organically, each representing 50% of our growth over this time horizon.

In October 2015, we completed the acquisition of SBM Financial, Inc. ("SBM"), the parent company of The Bank of Maine. This was and continues to be our largest acquisition over the Company's long history, with total acquired assets of $816.3 million, including loans of $628.0 million, and deposits and borrowings of $721.2 million. The acquisition provided us with an expanded presence in Southern and Central Maine, significant low-cost deposits (including interest and non-interest checking, savings and money market), and enhanced our mortgage banking platform.

Organic asset growth of $823.4 million over the past five years has been driven by organic loan growth of $694.4 million, which equated to a five-year compounded growth rate of 7% at December 31, 2019. Our organic growth over the past five

2

years was driven by market expansion in Southern and Central Maine and New Hampshire, as well as other strategic investments in people, technology and facilities over recent years.

The financial services industry continues to experience consolidations through mergers that could create opportunities for us to promote our value proposition to other financial institutions and financial service companies. We continue to evaluate the possibility of expansion into new markets through both de novo expansion and acquisitions. In addition, we are focused on maximizing growth across our current markets, and particularly those markets seen as growth markets where we currently have less of a presence and market share. Further details of our financial information can be found within the consolidated financial statements within Item 8. Financial Statements and Supplementary Data of this report.

Competition. We compete throughout Maine, and select areas of New Hampshire and Massachusetts. Our primary markets have historically been and continue to be within Maine. Within Maine, we operate in 13 of the state's 16 counties, with our primary markets and presence being throughout coastal and central Maine. Many of these markets are characterized as rural areas. Major competitors in our primary market area include local branches of large regional and national banking organizations and brokerage houses, as well as local independent banks, financial advisors, thrift institutions and credit unions. Other competitors for deposits and loans within our primary market area include insurance companies, money market funds, consumer finance companies and financing affiliates of consumer durable goods manufacturers.

3

We have effectively competed with other financial institutions by emphasizing customer service, highlighted by local decision-making, establishing long-term customer relationships, building customer loyalty and providing products and services designed to meet the needs of customers. Through Camden National Wealth Management and Camden Financial Consultants, we compete for trust, trust-related, investment management, individual retirement, foundation and endowment management services and brokerage services with local banks and non-banks, as well as with a number of brokerage firms and investment advisors with offices in our market area. In addition, most of these services are widely available to our customers by telephone, online and mobile channels through firms located outside our market area.

Employees. The Company employed639 people on a full- or part-time basis as of December 31, 2019.

Investor Relations. The Company’s Investor Relations information can be obtained through our internet address, CamdenNational.com. The Company makes available on or through its Investor Relations page, without charge, its annual reports on Form 10-K, quarterly reports on Form 10-Q, and current reports on Form 8-K and amendments to those reports filed or furnished pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934, as amended, as soon as reasonably practicable after such reports are electronically filed with, or furnished to, the SEC. The Company’s reports filed with, or furnished to, the SEC are also available at the SEC’s website at www.sec.gov. In addition, the Company makes available, free of charge, its press releases and Code of Ethics through the Company’s Investor Relations page. Information on our website is not incorporated by reference into this document and should not be considered part of this report.

Information Security. Information security, including cybersecurity, is a high priority for the Company. Recent, highly publicized events have highlighted the importance of cybersecurity, including cyberattacks against financial institutions, government agencies and other organizations that resulted in the compromise of personal and/or confidential information, the theft or destruction of corporate information, and demands for ransom payments to release corporate information encrypted by so-called “ransomware.” A successful cyberattack could harm the Company’s reputation and/or impair its ability to provide services to its customers. The Company has developed policies and technology designed to protect our own and our customers’ information from cyberattacks or loss, allow for the continuity of our business in the event of disruptions to the Company’s or its vendors’ critical systems and comply with regulatory requirements related to the protection of customer data, but cannot assure that it will be able to anticipate, detect, or implement effective preventative measures against all potential threats. Refer to related risk factors in Item 1A. Risk Factors below for additional information.

Supervision and Regulation

The following discussion addresses elements of the regulatory framework applicable to bank holding companies and their subsidiaries. This regulatory framework is intended primarily for the protection of depositors, the Federal Deposit Insurance Fund (“DIF”), and the banking system as a whole, rather than the protection of shareholders or non-depository creditors of a bank holding company such as the Company.

As a bank holding company, the Company is subject to regulation, supervision and examination by the Board of Governors of the Federal Reserve System (“FRB”) under the Bank Holding Company Act of 1956, as amended (“BHCA”). As a national bank, the Bank is subject to regulation, supervision and examination by the Office of the Comptroller of the Currency (“OCC”).

The following is a summary of certain aspects of various statutes and regulations applicable to the Company and its direct and indirect subsidiaries. This summary is not a comprehensive analysis of all applicable laws, and you should refer to the applicable statutes and regulations for more information. Changes in applicable laws or regulations, and in their interpretation and application by regulatory agencies and other governmental authorities, cannot be predicted, but may have a material effect on our business, financial condition or results of operations.

Regulation of the Company

As a bank holding company, the Company is subject to regulation, supervision and examination by the FRB, which has the authority, among other things, to order bank holding companies to cease and desist from unsafe or unsound banking practices; to assess civil money penalties; and to order termination of non-banking activities or termination of ownership and control of a non-banking subsidiary by a bank holding company.

Source of Strength. Under the Dodd-Frank Wall Street Reform and Consumer Protection Act (“Dodd-Frank Act”), the Company is required to serve as a source of financial strength for the Bank. This support may be required at times when the

5

Company may not have the resources to provide it. In the event of a bank holding company’s bankruptcy, any commitment by the bank holding company to a federal bank regulatory agency to maintain the capital of a bank subsidiary will be assumed by the bankruptcy trustee and entitled to a priority of payment.

Acquisitions and Activities. The BHCA prohibits a bank holding company, without prior approval of the FRB, from acquiring all or substantially all the assets of a bank, acquiring control of a bank, merging or consolidating with another bank holding company, or acquiring direct or indirect ownership or control of any voting shares of another bank or bank holding company if, after such acquisition, the acquiring bank holding company would control more than 5% of any class of the voting shares of such other bank or bank holding company. The BHCA also prohibits a bank holding company from engaging directly or indirectly in activities other than those of banking, managing or controlling banks or furnishing services to its subsidiary banks. However, a bank holding company may engage in and may own shares of companies engaged in activities that the FRB has determined, by order or regulation, to be so closely related to banking as to be a proper incident thereto.

Limitations on Acquisitions of Company Common Stock. The Change in Bank Control Act prohibits a person or group of persons acting in concert from acquiring “control” of a bank holding company unless the FRB has been notified and has not objected to the transaction. Under a rebuttable presumption established by the FRB, the acquisition of 10% or more of a class of voting securities of a bank holding company with a class of securities registered under Section 12 of the Exchange Act would generally constitute the acquisition of control of a bank holding company. In addition, the BHCA prohibits any company from acquiring control of a bank or bank holding company without first having obtained the approval of the FRB. Under the BHCA, a company is deemed to control a bank or bank holding company if the company owns, controls or holds with power to vote 25% or more of a class of voting securities of the bank or bank holding company, controls in any manner the election of a majority of directors or trustees of the bank or bank holding company, or the FRB determines that the company has the power to exercise a controlling influence over the management or policies of the bank or bank holding company.

Regulation of the Bank

The Bank is subject to regulation, supervision, and examination by the OCC. Additionally, the Federal Deposit Insurance Corporation (“FDIC”) has secondary supervisory authority as the insurer of the Bank’s deposits. The Bank is also subject to regulations issued by the Consumer Financial Protection Bureau (“CFPB”), as enforced by the OCC. Pursuant to the Dodd-Frank Act, the FRB may directly examine the subsidiaries of the Company, including the Bank. The enforcement powers available to the federal banking regulators include, among other things, the ability to issue cease and desist or removal orders; to terminate insurance of deposits; to assess civil money penalties; to issue directives to increase capital; to place the Bank into receivership; and to initiate injunctive actions against banking organizations and institution-affiliated parties.

Deposit Insurance. The deposit obligations of the Bank are insured by the FDIC’s DIF up to the applicable limits. Under the Federal Deposit Insurance Act (“FDIA”), insurance of deposits may be terminated by the FDIC if the FDIC finds that the insured depository institution has engaged in unsafe and unsound practices, is in an unsafe or unsound condition to continue operations or has violated any applicable law, regulation, rule, order or condition imposed by the FDIC.

The Bank’s deposits are subject to deposit insurance assessments to maintain the DIF. The Bank’s deposit insurance assessments are based on its assets. To determine its deposit insurance assessment, the Bank computes the base amount of its average consolidated assets less its average tangible equity (defined as the amount of Tier I capital) and the applicable assessment rate. The rule for calculating assessment rates for established small banks, including the Bank, utilizes the CAMELS rating system, which is a supervisory rating system designed to take into account and reflect all financial and operational risks that a bank may face, including capital adequacy, asset quality, management capability, earnings, liquidity and sensitivity to market risk. Each of the seven financial ratios and a weighted average of CAMELS component ratings is multiplied by a corresponding pricing multiplier. The sum of these products is added to a uniform amount, with the resulting sum being an institution’s initial base assessment rate (subject to minimum or maximum assessment rates based on a bank’s CAMELS composite rating). This method takes into account various measures, including an institution’s leverage ratio, brokered deposit ratio, one year asset growth, the ratio of net income before taxes to total assets and considerations related to asset quality. Assessments for established small banks range from 1.5 to 30 basis points, after adjustments. The FDIC has the power to adjust deposit insurance assessment rates at any time, and the Company is not able to predict the amount or timing of any adjustment.

The FDIA, as amended by the Federal Deposit Insurance Reform Act and the Dodd-Frank Act, establishes a minimum reserve ratio of the DIF to estimated insured deposits of 1.15% prior to September 2020 and 1.35% thereafter. Further, the Dodd-Frank Act required that, in setting assessments, the FDIC offset the effect of the increase in the minimum reserve ratio from 1.15% to 1.35% on banks with less than $10 billion in assets.

6

To offset the effect of the increase in the reserve ratio on small banks, including the Bank, those banks will receive credits for the portion of their assessments that helped to raise the reserve ratio from 1.15% to 1.35%. Credits will be applied automatically to reduce a small bank’s regular assessment in each quarter that the reserve ratio is at least 1.38%, up to the entire amount of the credit or assessment.

Activities and Investments of National Banking Associations. National banking associations must comply with the National Bank Act and the regulations promulgated thereunder by the OCC, which limit the activities of national banking associations to those that are deemed to be part of, or incidental to, the “business of banking.” Activities that are part of, or incidental to, the business of banking include taking deposits, borrowing and lending money and discounting or negotiating promissory notes, drafts, bills of exchange, and other evidences of debt. Subsidiaries of national banking associations generally may only engage in activities permissible for the parent national bank.

Lending Restrictions. Federal law limits a bank’s authority to extend credit to its insiders, including its directors, executive officers and 10% shareholders, as well as to entities controlled by such persons. Among other things, extensions of credit to insiders are required to be made on terms that are substantially the same as, and follow credit underwriting procedures that are not less stringent than, those prevailing for comparable transactions with unaffiliated persons. Also, the terms of such extensions of credit may not involve more than the normal risk of repayment or present other unfavorable features and may not exceed certain limitations on the amount of credit extended to such persons, individually and in the aggregate, which limits are based, in part, on the amount of the bank’s capital. The Dodd-Frank Act explicitly provides that an extension of credit to an insider includes credit exposure arising from a derivatives transaction, repurchase agreement, reverse repurchase agreement, securities lending transaction or securities borrowing transaction. Additionally, the Dodd-Frank Act requires that asset sale transactions with insiders must be on market terms, and if the transaction represents more than 10% of the capital and surplus of the Bank, be approved by a majority of the disinterested directors of the Bank.

Brokered Deposits. Section 29 of the FDIA and FDIC regulations generally limit the ability of an insured depository institution to accept, renew or roll over any brokered deposit unless the institution’s capital category is “well capitalized” under the prompt corrective action framework described below or, with a waiver from the FDIC, “adequately capitalized.” A bank that is “adequately capitalized” and that accepts or renews brokered deposits subject to a waiver from the FDIC is subject to additional restrictions on the interest rates it may offer. Depository institutions that have brokered deposits in excess of 10% of total assets will be subject to increased FDIC deposit insurance premium assessments. The Economic Growth, Regulatory Relief, and Consumer Protection Act (“EGRRCPA”) amended Section 29 of the FDIA to exempt a capped amount of reciprocal deposits from treatment as brokered deposits. In December 2018, the FDIC adopted a final rule that permits an institution that is “well capitalized” and has a CAMELS composite rating of 1 or 2 to exempt reciprocal deposits from treatment as brokered deposits up to the lesser of $5 billion or 20% of the institution’s total liabilities. Institutions that are not well rated or “well capitalized” may treat reciprocal deposits as non-brokered up to an amount equal to a “special cap” set forth in the final rule. In addition, in December 2019, the FDIC issued a proposed rule that is intended to bring the brokered deposits regulations in line with modern deposit taking methods and that may reduce the amount of deposits that would be classified as brokered. The impact on the Bank from any changes to the brokered deposit regulations will depend on the final form of the proposed rule.

Community Reinvestment Act. The Community Reinvestment Act (“CRA”) requires the OCC to evaluate the Bank’s performance in helping to meet the credit needs of the entire communities it serves, including low and moderate-income neighborhoods, consistent with its safe and sound banking operations, and to take this record into consideration when evaluating certain applications. The OCC’s CRA regulations are generally based upon objective criteria of the performance of institutions under three key assessment tests: (i) a lending test, to evaluate the institution’s record of making loans in its service areas; (ii) an investment test, to evaluate the institution’s record of investing in community development projects, affordable housing, and programs benefiting low- or moderate-income individuals and businesses; and (iii) a service test, to evaluate the institution’s delivery of services through its branches, ATMs, and other offices. The OCC rates a national bank’s compliance with the CRA as “Outstanding,” “Satisfactory,” “Needs to Improve” or “Substantial Noncompliance.” Failure of the Bank to receive at least a “Satisfactory” rating could inhibit the Bank or the Company from undertaking certain activities, including acquisitions of other financial institutions. The Bank currently has an “Outstanding” CRA rating.

In December 2019, the OCC and the FDIC proposed a rule that would seek to expand the types of activities that qualify for CRA credit; revise how banks delineate their CRA assessment areas; and establish new standards for evaluating banks with more than $500 million in assets, including, among others, the number of qualifying retail loan originations to low- and moderate-income individuals. The impact on the Bank from any changes to the CRA regulations will depend on the final form of the proposed rule and how it is implemented and applied.

Capital Adequacy and Safety and Soundness

Regulatory Capital Requirements. The Companyand the Bank are subject to risk-based capital requirements and rules issued by the FRB, the OCC and the FDIC (the “Capital Rules”) that are based on the Basel Committee on Banking Supervision’s (“Basel Committee”) framework for strengthening capital and liquidity regulation (referred to as Basel III). The Capital Rules are intended to reflect the relationship between the banking organization’s capital and the degree of risk associated with its operations based on transactions recorded on-balance sheet as well as off-balance sheet items. The FRB and the OCC may from time to time require that a banking organization maintain capital above the minimum levels discussed below, due to the banking organization’s financial condition or actual or anticipated growth. Under the Capital Rules, the Company and the Bank apply the Standardized Approach in measuring their risk-weighted assets (“RWA”) and regulatory capital.

The Capital Rules define qualifying capital instruments and specify minimum amounts of capital as a percentage of assets that banking organizations are required to maintain.

Under the Capital Rules, risk-based capital ratios are calculated by dividing Common Equity Tier 1 (“CET1”) capital, Tier 1 capital and total risk-based capital, respectively, by RWA. Assets and off-balance sheet credit equivalents are assigned a risk weight based primarily on supervisory assessments of relative credit risk.

Under the Capital Rules, the Company and the Bank are each required to maintain a minimum CET1 capital to RWA ratio of 4.5%, a minimum Tier 1 capital to RWA ratio of 6%, a minimum total capital to RWA ratio of 8% and a minimum leverage ratio of 4%. Additionally, the Capital Rules require an institution to establish a capital conservation buffer of CET1 capital in an amount above the minimum risk-based capital requirements for “adequately capitalized” institutions equal to 2.5% of total RWA, resulting in a requirement for the Company and the Bank effectively to maintain CET1, Tier 1 and total capital ratios of 7%, 8.5% and 10.5%, respectively. Banking institutions with a ratio of CET1 capital to RWA above the minimum requirement but below the capital conservation buffer face 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, four quarter trailing net income, net of distributions and tax effects not reflected in net income).

The Capital Rules provide for a number of deductions from and adjustments to CET1 capital, including, for example, goodwill, other intangible assets, and deferred tax assets (“DTAs”) that arise from net operating loss and tax credit carryforwards net of any related valuation allowance. Mortgage servicing rights (“MSRs”), DTAs arising from temporary differences that could not be realized through net operating loss carrybacks and significant investments in non-consolidated financial institutions must also be deducted from CET1 capital to the extent that they exceed certain thresholds. In November 2017, the federal bank regulators revised the Capital Rules to extend the transitional treatment of certain DTAs, MSRs, investments in non-consolidated financial institutions and minority interests for non-advanced approaches banking organizations, such as the Company and the Bank, until January 1, 2020, when the revisions to simplify the regulatory capital treatment of those items took effect.

The Company and the Bank, as non-advanced approaches banking organizations, made a one-time, permanent election under the Capital Rules to exclude the effects of certain components of accumulated other comprehensive income (“AOCI”) included in shareholders’ equity under U.S. GAAP in determining regulatory capital ratios.

The EGRRCPA requires the federal bank regulators to adopt regulations to implement an exemption from the Capital Rules for smaller banking organizations, including the Company and the Bank, that maintain a “Community Bank Leverage Ratio” of at least 8% to 10%. Specifically, the legislation provides that if any depository institution or depository institution holding company with less than $10 billion in total consolidated assets maintains tangible equity in excess of this leverage ratio, as implemented by the federal bank regulators, it would be deemed to be in compliance with (i) the leverage and risk-based capital requirements promulgated by the federal banking agencies; (ii) in the case of a depository institution, the capital ratio requirements to be considered “well-capitalized” under the federal banking agencies’ “prompt corrective action” regime (see “—Prompt Corrective Action” below); and (iii) “any other capital or leverage requirements” to which the depository institution or holding company is subject, unless the appropriate federal banking agency determines otherwise based on the particular institution’s risk profile.

In November 2019, the FRB, OCC and FDIC issued a final rule to implement the Community Bank Leverage Ratio. Under the final rule, a “qualifying small banking organization” can choose to apply the Community Bank Leverage Ratio framework if its Community Bank Leverage Ratio (i.e., the ratio of its Tier 1 capital to average total consolidated assets minus certain deductions from total assets), is greater than 9%. The Company has evaluated the potential impact of this rule and has elected not to apply the Community Bank Leverage Ratio framework to its operations at this time, and will instead continue to measure

8

its capital adequacy under the Capital Rules as described above. Under the final rule, as long as the Company and the Bank continue to meet the requirements to be qualifying small banking organizations (i.e., they have less than $10 billion in total consolidated assets and meet certain risk-based criteria), they are permitted to opt into (or out of) the Community Bank Leverage Ratio framework at any time and for any reason. The Company will continue to evaluate the impact of the Community Bank Leverage Ratio and may opt into that framework in the future. The Company cannot guarantee, however, that it or the Bank will continue to meet the conditions to be eligible to apply the Community Bank Leverage Ratio, nor can the Company predict at this time whether it or the Bank will choose to apply the Community Bank Leverage Ratio in the future.

In December 2017, the Basel Committee published standards that it described as the finalization of the Basel III post-crisis regulatory reforms (the standards are commonly referred to as “Basel IV”). Among other things, these standards revise the Basel Committee's standardized approach for credit risk (including by recalibrating risk weights and introducing new capital requirements for certain "unconditionally cancellable commitments," such as home equity lines of credit) and provides a new standardized approach for operational risk capital. Under the Basel framework, these standards will generally be effective on January 1, 2022, with an aggregate output floor phasing in through January 1, 2027. Under the current U.S. capital rules, operational risk capital requirements and a capital floor apply only to advanced approaches institutions, and not to the Company or Bank. The impact of Basel IV on the Company and the Bank will depend on the manner in which it is implemented by the federal bank regulators.

Prompt Corrective Action. The FDIA requires the federal banking agencies to take prompt corrective action with respect to depository institutions that do not meet the minimum capital requirements described above. The FDIA establishes five capital categories (“well capitalized,” “adequately capitalized,” “undercapitalized,” “significantly undercapitalized” and “critically undercapitalized”).The federal banking regulators must take certain mandatory supervisory actions, and are authorized to take other discretionary actions, with respect to institutions that are less than adequately capitalized, with supervisory actions progressively becoming more punitive as the institution’s capital category declines. Supervisory actions include: (i) restrictions on payment of capital distributions and management fees, (ii) requirements that a federal bank regulator monitor the condition of the institution and its efforts to restore its capital, (iii) submission of a capital restoration plan, (iv) restrictions on the growth of the institution’s assets and (v) requirements for prior regulatory approval of certain expansion proposals. A bank that is “critically undercapitalized” (i.e., has a ratio of tangible equity to total assets that is equal to or less than 2.0%) will be subject to further restrictions and generally will be placed in conservatorship or receivership within 90 days. An insured depository institution is considered “well capitalized” if it (i) has a total risk-based capital ratio of 10.0% or greater; (ii) has a Tier 1 risk-based capital ratio of 8.0% or greater; (iii) has a CET1 ratio of at least 6.5% or greater; (iv) has a leverage capital ratio of 5.0% or greater; and (v) is not subject to any written agreement, order, capital directive, or prompt corrective action directive to meet and maintain a specific capital level for any capital measure.

The FDIA’s prompt corrective action provisions apply only to depository institutions such as the Bank, and not to bank holding companies. Under the FRB’s regulations, a bank holding company, such as the Company, is considered “well capitalized” if the bank holding company (i) has a total risk based capital ratio of at least 10%, (ii) has a Tier 1 risk-based capital ratio of at least 6%, and (iii) is not subject to any written agreement order, capital directive or prompt corrective action directive to meet and maintain a specific capital level for any capital measure. Although prompt corrective action regulations apply only to depository institutions and not tobank holding companies, a bank that is required to submit a capital restoration plan generally must concurrently submit a performance guarantee by its parent holding company. The liability of the parent holding company under any such guarantee is limited to the lesser of five percent of the bank’s assets at the time it became “undercapitalized” or the amount needed to comply.

Information concerning the Company and the Bank with respect to capital requirements is incorporated by reference

from Item 7. "Management’s Discussion and Analysis of Financial Condition and Results of Operations—Capital

Resources" and Note 14 of the consolidated financial statements included within this report.

The Bank and the Company meet all capital requirements under the Capital Rules, including the capital conservation buffer, and each meet the capital ratio requirements to be “well capitalized” for purposes of the prompt corrective action provisions of the FDIA and applicable FRB regulations, respectively.

Safety and Soundness Standards. The FDIA requires the federal bank regulatory agencies to prescribe safety and soundness standards, by regulations or guidelines, as the agencies deem appropriate. Guidelines adopted by the federal bank regulatory agencies establish general standards relating to internal controls and information systems, internal audit systems, loan documentation, credit underwriting, interest rate exposure, asset growth, asset quality, earnings and compensation, fees and benefits. In general, these guidelines require, among other things, appropriate systems and practices to identify and manage the risk and exposures specified in the guidelines. The guidelines prohibit excessive compensation as an unsafe and unsound practice and describe compensation as excessive when the amounts paid are unreasonable or disproportionate to the services

9

performed by an executive officer, employee, director or principal shareholder. In addition, the federal banking agencies adopted regulations that authorize, but do not require, an agency to order an institution that has been given notice by an agency that it is not satisfying any of such safety and soundness standards to submit a compliance plan. If, after being so notified, an institution fails to submit an acceptable compliance plan or fails in any material respect to implement an acceptable compliance plan, the agency must issue an order directing action to correct the deficiency and may issue an order restricting asset growth, requiring an institution to increase its ratio of tangible equity to assets or directing other actions of the types to which an undercapitalized institution is subject under the “prompt corrective action” provisions of the FDIA. See “—Prompt Corrective Action” above. If an institution fails to comply with such an order, the agency may seek to enforce such order in judicial proceedings and to impose civil money penalties.

Dividend and Share Repurchase Restrictions

The Company is a legal entity separate and distinct from its subsidiaries. The revenue of the Company (on a parent-only basis) is derived primarily from interest and dividends paid to it by the Bank. The right of the Company, and consequently the right of shareholders of the Company, to participate in any distribution of the assets or earnings of the Bank through the payment of such dividends or otherwise is necessarily subject to the prior claims of creditors of the Bank (including depositors), except to the extent that certain claims of the Company in a creditor capacity may be recognized. The Company and the Bank are subject to various federal and state restrictions on their ability to pay dividends as described below.

Restrictions on Bank Holding Company Dividends. The FRB has the authority to prohibit bank holding companies from paying dividends if such payment is deemed to be an unsafe or unsound practice. The FRB has indicated generally that it may be an unsafe or unsound practice for bank holding companies to pay dividends unless the bank holding company’s net income over the preceding year is sufficient to fund the dividends and the expected rate of earnings retention is consistent with the organization’s capital needs, asset quality and overall financial condition. Further, the Company’s ability to pay dividends is restricted if it does not maintain the capital conservation buffer. See “—Capital Adequacy and Safety and Soundness—Regulatory Capital Requirements” above.

Under Maine law, a corporation’s Board of Directors may declare, and the corporation may pay, dividends on its outstanding shares, in cash or other property, generally only out of the corporation’s unreserved and unrestricted earned surplus, or out of the unreserved and unrestricted net earnings of the current fiscal year and the next preceding fiscal year taken as a single period, except under certain circumstances, including when the corporation is insolvent, or when the payment of the dividend would render the corporation insolvent or when the declaration would be contrary to the corporation’s charter.

Restrictions on Bank Dividends. Under OCC regulations, national banks 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 national bank in any calendar year exceeds the total of the national bank’s retained net income year-to-date combined with its retained net income for the preceding two years. National banks also are prohibited from declaring or paying any dividend if, after making the dividend, the national bank would be considered “undercapitalized” (as defined by reference to other OCC regulations). The OCC has the authority to use its enforcement powers to prohibit a national bank, such as the Bank, from paying dividends if, in its opinion, the payment of dividends would constitute an unsafe or unsound practice. Further, the Bank’s ability to pay dividends is restricted if it does not maintain the capital conservation buffer. See “—Capital Adequacy and Safety and Soundness—Regulatory Capital Requirements” above.

Restrictions on Share Repurchases. In July 2019, the FRB eliminated the standalone prior approval requirement in the Capital Rules for a bank holding company’s repurchase or redemption of its common stock. In certain circumstances, however, the Company’s repurchases of its common stock may be subject to a prior approval or notice requirement under the regulations or policies of the FRB.

Certain Transactions by Banks with their Affiliates

Sections 23A and 23B of the Federal Reserve Act and the FRB’s Regulation W restrict transactions between a bank and its affiliates, including its parent bank holding company. The Bank is subject to these restrictions, which include quantitative and qualitative limits on the amounts and types of transactions that may occur, including extensions of credit (which include credit exposure arising from repurchase and reverse repurchase agreements, securities borrowing and derivative transactions) to affiliates, investments in the stock or securities of affiliates, purchases of assets from affiliates and other “covered transactions.” Generally, a bank’s (including its subsidiaries) covered transactions with any affiliate are subject to the following limits: (i) the aggregate amount of covered transactions with any one affiliate cannot exceed 10% of the bank’s capital stock and surplus; and (ii) the aggregate amount of covered transactions with all affiliates cannot exceed 20% of the bank’s capital stock and surplus.

10

Transactions between a bank and its affiliates, including a parent holding company, must be on market terms and not otherwise unduly favorable to an affiliate, and, in the case of extensions of credit, be secured by specified amounts and types of collateral.

Anti-Tying Restrictions

Generally, a bank is prohibited from extending credit, leasing or selling property, furnishing any service or fixing or varying the consideration for any of the foregoing on the condition that (i) the customer obtains additional credit, property or services from the bank’s parent holding company or any subsidiary of the holding company, or (ii) the customer will not obtain credit, property or services from a competitor of the bank or its affiliates (except to the extent the restriction is a reasonable condition imposed to assure the soundness of the credit extended).

Consumer Protection Regulation

The Company and the Bank are subject to federal and state laws designed to protect consumers and prohibit unfair or deceptive business practices, including the Equal Credit Opportunity Act, the Fair Housing Act, the Home Ownership Protection Act, the Fair Credit Reporting Act, as amended by the Fair and Accurate Credit Transactions Act of 2003 (“FACT Act”), the Gramm-Leach-Bliley Act of 1999 (“GLBA”), the Truth in Lending Act, the CRA, the Home Mortgage Disclosure Act, the Real Estate Settlement Procedures Act, the National Flood Insurance Act and various state law counterparts. These laws and regulations mandate certain disclosure requirements and regulate the manner in which financial institutions must interact with customers when taking deposits, making loans, collecting loans and providing other services. In addition, the CFPB has a broad mandate to prohibit unfair, deceptive or abusive acts and practices, is specifically empowered to require certain disclosures to consumers and draft model disclosure forms, and is responsible for making rules and regulations under the federal consumer protection laws relating to financial products and services. Failure to comply with consumer protection laws and regulations can subject financial institutions to enforcement actions, fines and other penalties. The OCC examines the Bank for compliance with CFPB rules and enforces CFPB rules with respect to the Bank.

Mortgage Reform. The Dodd-Frank Act prescribes certain standards that mortgage lenders must consider before making a residential mortgage loan, including verifying a borrower’s ability to repay such mortgage loan, and allows borrowers to assert violations of certain provisions of the Truth in Lending Act as a defense to foreclosure proceedings. Under the Dodd-Frank Act, prepayment penalties are prohibited for certain mortgage transactions and creditors are prohibited from financing insurance policies in connection with a residential mortgage loan or home equity line of credit. In addition, the Dodd-Frank Act prohibits mortgage originators from receiving compensation based on the terms of residential mortgage loans and generally limits the ability of a mortgage originator to be compensated by others if compensation is received from a consumer. The Dodd-Frank Act requires mortgage lenders to make additional disclosures prior to the extension of credit, in each billing statement and for negative amortization loans and hybrid adjustable rate mortgages.

Privacy and Customer Information Security. The GLBA requires financial institutions to implement policies and procedures regarding the disclosure of nonpublic personal information about consumers to nonaffiliated third parties. In general, the Bank must provide its customers with an initial and annual disclosure that explains its policies and procedures regarding the disclosure of such nonpublic personal information, and, except as otherwise required or permitted by law, the Bank is prohibited from disclosing such information except as provided in such policies and procedures. However, an annual disclosure is not required to be provided by a financial institution if the financial institution only discloses information under exceptions from GLBA that do not require an opt out to be provided and if there has been no change in its privacy policies and practices since its most recent disclosure provided to consumers. The GLBA also requires that the Bank develop, implement and maintain a comprehensive written information security program designed to ensure the security and confidentiality of customer information (as defined under GLBA), to protect against anticipated threats or hazards to the security or integrity of such information; and to protect against unauthorized access to or use of such information that could result in substantial harm or inconvenience to any customer. The Bank is also required to send a notice to customers whose sensitive information has been compromised if unauthorized use of this information is reasonably possible. Most states, including the states where the Bank operates, have enacted legislation concerning breaches of data security and Congress is considering federal legislation that would require consumer notice of data security breaches. Pursuant to the FACT Act, the Bank must develop and implement a written identity theft prevention program to detect, prevent, and mitigate identity theft in connection with the opening of certain accounts or certain existing accounts. Additionally, the FACT Act amends the Fair Credit Reporting Act to generally prohibit a person from using information received from an affiliate to make a solicitation for marketing purposes to a consumer, unless the consumer is given notice and a reasonable opportunity and a reasonable and simple method to opt out of the making of such solicitations.

11

Anti-Money Laundering

The Bank Secrecy Act. Under the Bank Secrecy Act (“BSA”), as amended by the USA PATRIOT Act of 2001, a financial institution is required to have systems in place to detect certain transactions, based on the size and nature of the transaction, and to monitor and report suspicious activity to appropriate law enforcement or regulatory authorities. Financial institutions, such as the Bank, are also required to adopt and implement policies and procedures with respect to, among other things, anti-money laundering (“AML”) compliance, suspicious activity, currency transaction reporting, customer identity verification and customer risk analysis. In addition, financial institutions are required to take steps to monitor their correspondent banking and private banking relationships as well as, if applicable, their relationships with “shell banks.” In evaluating an application under Section 3 of the BHCA to acquire a bank or an application under the Bank Merger Act to merge banks or affect a purchase of assets and assumption of deposits and other liabilities, the applicable federal banking regulator must consider the AML compliance record of both the applicant and the target.

OFAC. The U.S. has imposed economic sanctions that affect transactions with designated foreign countries, nationals and others. These sanctions, which are administered by the U.S. Treasury’s Office of Foreign Assets Control (“OFAC”), take many different forms. Generally, however, they contain one or more of the following elements: (i) restrictions on trade with or investment in a sanctioned country, including prohibitions against direct or indirect imports from and exports to a sanctioned country and prohibitions on “U.S. persons” engaging in financial or other transactions relating to a sanctioned country or with certain designated persons and entities; (ii) a blocking of assets in which the government or specially designated nationals of the sanctioned country have an interest, by prohibiting transfers of property subject to U.S. jurisdiction (including property in the possession or control of U.S. persons); and (iii) restrictions on transactions with or involving certain persons or entities. Blocked assets (for example, property and bank deposits) cannot be paid out, withdrawn, set off or transferred in any manner without a license from OFAC. Failure to comply with these sanctions could have serious legal and reputational consequences for the Company.

Regulation of Other Activities

Volcker Rule Restrictions on Proprietary Trading and Sponsorship of Hedge Funds and Private Equity Funds. Since its enactment, the Dodd-Frank Act has barred banking organizations, such as the Company and the Bank, from engaging in proprietary trading and from sponsoring and investing in hedge funds and private equity funds, except as permitted under certain circumstances, in a provision commonly referred to as the “Volcker Rule.”

The EGRRCPA amended the Volcker Rule to exclude smaller banking organizations, effective immediately following enactment of the EGRRCPA. In July 2019, the OCC, FRB, FDIC, SEC and Commodity Futures Trading Commission jointly issued a final rule to implement the EGRRCPA’s exclusion with respect to small banking organizations. Under the final rule, an insured depository institution, such as the Bank, that has, and is controlled only by companies that have, (i) total consolidated assets of $10 billion or less, and (ii) total trading assets and liabilities that are 5% or less of total assets generally would not be a “banking entity” and therefore would not be subject to the Volcker Rule. As a result, the Company and the Bank are no longer subject to the Volcker Rule. We do not expect this change to have a material impact on the Company.

12

Item 1A. Risk Factors

An investment in the Company involves risk, which could be substantial. Market, liquidity, credit, operational, legal, compliance, reputational and strategic risks are inherent in our business. The material risks and uncertainties that management believes affect the Company are described below. Any of the following risks could affect the Company’s financial condition and results of operations and could be material and/or adverse in nature. You should consider all of the following risks together with all of the other information in this Annual Report on Form 10-K.

Risks Related to the Operation of Our Business

Our loans are concentrated in certain areas of Maine and adverse conditions in those markets could adversely affect our operations.

We primarily serve individuals and businesses located in the state of Maine, with 76% of our loan portfolio concentrated among borrowers in Maine as of December 31, 2019, with higher concentrations of exposure in Cumberland, Hancock, Kennebec, Knox, Penobscot and York counties. Further, because a substantial portion of the loan portfolio is secured by real estate in this area, the value of the associated collateral is also subject to regional real estate market conditions. Adverse economic, political or business developments or natural hazards may affect these areas and the ability of property owners in these areas to make payments of principal and interest on the underlying mortgages. If these regions experience adverse economic, political or business conditions, we would likely experience higher rates of loss and delinquency on these loans than if the loans were more geographically diverse.

We experience strong competition within our markets, which may impact our profitability.

Competition in the banking and financial services industry is strong. In our market areas, we compete for loans, deposits and other financial products and services with large financial companies, local independent banks, thrift institutions, savings institutions, mortgage brokerage firms, credit unions, finance companies, mutual funds, insurance companies, brokerage and investment banking firms, and other financial intermediaries that offer similar services. Some of these competitors have substantially greater resources and lending limits than those of the Bank and may offer services that the Bank does not or cannot provide. Some of our non-bank competitors are not subject to the same extensive regulations we are, and, as a result, may be able to compete more effectively for business. In particular, the activity of marketplace lenders and other financial technology companies (“fintechs”) has grown significantly over recent years and is expected to continue to grow. Fintechs have and may continue to offer bank or bank-like products. For example, a number of fintechs have applied for bank or industrial loan charters. In addition, other fintechs have partnered with existing banks to allow them to offer deposit products to their customers. Regulatory changes, such as the recently proposed revisions to the FDIC’s rules on brokered deposits, may also make it easier for fintechs to partner with banks and offer deposit products. There is also increased competition by out-of-market competitors through online and mobile channels. Our long-term success depends on our ability to compete successfully with other financial institutions and fintechs. Because we maintain a smaller staff and have fewer financial and other resources than larger institutions with which we compete, we may be limited in our ability to attract customers. If we are unable to attract and retain customers, we may be unable to achieve growth in the loan and core deposit portfolios, and our results of operations and financial condition may be negatively impacted.

Our loan portfolio includes commercial real estate and commercial loans, which are generally riskier than other types of loans.

At December 31, 2019, our commercial real estate and commercial loan portfolios comprised 54% of our total loan balances. Commercial loans generally carry larger loan balances and involve a higher risk of nonpayment or late payment than residential mortgage loans. Commercial loans may lack standardized terms and may include a balloon payment feature. The ability of a borrower to make or refinance a balloon payment may be affected by a number of factors, including the financial condition of the borrower, prevailing economic conditions and prevailing interest rates. Repayment of these loans is generally more dependent on the economy and the successful operation of a business. Because of the risks associated with commercial loans, we may experience higher rates of default than if the portfolio were more heavily weighted toward residential mortgage loans. Higher rates of default could have an adverse effect on our financial condition and results of operations.

As of December 31, 2019, the most significant industry concentration within our loan portfolio was nonresidential building operators (operators of commercial and industrial buildings, retail establishments, theaters, banks and insurance buildings), which was 12% of our total loans and 31% of our total commercial real estate portfolio. As of December 31, 2019, we had no other industry concentrations in excess of 10% of total loans.

13

If our allowance for loan losses is not adequate to cover actual loan losses, our earnings could decrease.

We make various assumptions and judgments about the collectability of our loan portfolio and provide an allowance for probable loan losses based on a number of factors. On a monthly basis, management reviews the allowance for loan losses to assess recent asset quality trends and impact on the Company's financial condition. On a quarterly basis, the allowance for loan losses is reviewed and approved at the Bank's Board of Directors meeting. If our assumptions are incorrect, the allowance for loan losses may not be sufficient to cover the losses we could experience, which would have an adverse effect on operating results, and may also cause us to increase the allowance for loan losses in the future. In addition, bank regulators periodically review our allowance for loan losses and may require us to increase our provisions for credit losses or recognize further loan charge-offs. Any increase in our allowance for loan losses or loan charge-offs as required by regulatory authorities could have a material adverse effect on our consolidated results of operations and financial condition. If additional amounts are provided to the allowance for loan losses, our earnings could decrease.

Fluctuations in market interest rates may adversely affect our performance.

Our profitability depends to a large extent upon our net interest income, which is the difference between interest income earned from loans and investments and the interest expense paid on deposits and borrowings. Net interest income is our largest source of revenue and can be affected significantly by changes in market interest rates. In particular, changes in relative interest rates may reduce our net interest income as the difference between interest income and interest expense decreases. As a result, we have adopted asset and liability management policies to minimize the potential adverse effects of changes in interest rates on net interest income, primarily by altering the mix and maturity of loans, investments and funding sources.

As of December 31, 2019, our balance sheet composition supported an asset sensitive interest rate risk position over a one- and two-year period. This would suggest that if interest rates were to decrease, then net interest income would decrease, reducing revenue and net income, while an increase in interest rates would increase net interest income, increasing revenue and net income. However, there can be no assurance that a change in interest rates will not negatively impact our results of operations or financial condition. Because market interest rates may change by differing magnitudes and at different times, significant changes in interest rates over an extended period of time could reduce overall net interest income. An increase in interest rates could also have a negative impact on our results of operations by slowing loan production, and specifically, loan refinance activity, and/or reducing the ability of borrowers to repay their current loan obligations, which could not only result in increased loan defaults, foreclosures and write-offs, but also necessitate further increases to our allowance for loan losses.

A downgrade or potential downgrade of the U.S. Government's sovereign credit rating by one or more credit ratings agencies could adversely affect our business.

Future uncertainty over U.S. fiscal policy could result in a downgrade or a reduction in the outlook of the U.S. long-term sovereign credit rating by one or more credit ratings agencies. Any downgrade, or perceived future downgrade, in the U.S. sovereign credit rating or outlook could adversely affect global financial markets and economic conditions and may result in, among other things, increased volatility and illiquidity in the capital markets, declines in consumer confidence, increased unemployment levels and declines in the value of U.S. Treasury securities and securities guaranteed by the U.S. government. As a result, our business, liquidity, results of operations and financial conditions may be adversely affected. Additionally, the economic conditions resulting from any such downgrade or perceived future downgrade may significantly exacerbate the other risks we face.

Our cost of funds may increase as a result of loss of deposits or a change in deposit mix.

Deposits are a low cost, stable source of funding. We compete with banks, other financial institutions and fintechs for deposits. Funding costs may increase if we lose deposits and are forced to replace them with more expensive sources of funding, if clients shift their deposits into higher cost products or if we need to raise interest rates to avoid losing deposits. Higher funding costs reduce our net interest margin, net interest income and net income.

As of December 31, 2019, brokered deposits made up 5% of our total deposits. We have and will continue to utilize brokered deposits when it is a more cost effective source of funding compared to alternative funding sources. Should we become less than well-capitalized under the prompt corrective action framework, our use of brokered deposits may be limited, which could result in the use of more costly funding sources that would reduce our net interest margin, net interest income and net income. See “Supervision and Regulation-Capital Adequacy and Safety and Soundness-Prompt Corrective Action”and“Supervision and Regulations-Regulation of the Bank-Brokered Deposits” for additional information on the prompt corrective action framework and the regulation of brokered deposits.

14

Wholesale funding sources may prove insufficient to replace deposits and support our operations and future growth.

The Company and the Bank must maintain sufficient funds to respond to the needs of depositors and borrowers. To manage liquidity, we draw upon a number of funding sources in addition to core deposit growth and repayments and maturities of loans and investments. These sources include brokered deposits, borrowings through the Federal Home Loan Bank and correspondent banks, proceeds from the sale of investments and loans, and liquidity resources at the holding company. Our ability to manage liquidity will be severely constrained if we are unable to maintain access to funding or if adequate financing is not available to accommodate future growth at acceptable costs. In addition, if we are required to rely more heavily on more expensive funding sources to support future growth, our revenues may not increase proportionately to cover our costs. In this case, operating margins and profitability would be adversely affected. Turbulence in the capital and credit markets may adversely affect our liquidity and financial condition and the willingness of certain counterparties and customers to do business with us.

We could be adversely affected by the actions and commercial soundness of other financial institutions.

Our ability to engage in routine funding transactions could be adversely affected by the actions and commercial soundness of other financial institutions. Financial services institutions are interrelated as a result of trading, clearing, counterparty and other relationships. We maintain a diversified securities portfolio and have exposure to many different counterparties, and we routinely execute transactions with counterparties in the financial industry, including brokers and dealers, other commercial banks, investment banks, mutual and hedge funds, and other financial institutions. As a result, defaults by, or even rumors or questions about, one or more financial services institutions, or the financial services industry generally, could lead to market-wide liquidity problems and losses or defaults by us or by other institutions and organizations. Many of these transactions expose us to credit risk in the event of default of our counterparty or client. Furthermore, our credit risk may be exacerbated when the collateral held by us cannot be liquidated or is liquidated at prices not sufficient to recover the full amount of the financial instrument exposure due to us. There is no assurance that any such losses would not materially and adversely affect our results of operations.

We believe that we have adequately reviewed our investment securities for impairment and we did not recognize any other-than-temporary impairments on our investment securities portfolio in 2019. However, over time, the economic and market environment may provide additional insight regarding the fair value of certain securities, which could change our judgment regarding impairment. In addition, if a counterparty should default, become insolvent, declare bankruptcy, or otherwise cease to exist, the value of our investment may be impaired. This could result in realized losses relating to other-than-temporary declines being charged against future income. Given the significant judgments involved, there is risk that material other-than-temporary impairments may be charged to income in future periods, resulting in realized losses.

Market changes may adversely affect demand for our services and impact results of operations.

Channels for servicing our customers are evolving rapidly, with less reliance on traditional branches, more use of online and mobile banking, and increased demand for universal bankers and other relationship managers who can service multiple product lines. We compete with larger providers that are rapidly evolving their service offerings, thereby escalating the costs of evolving the Bank’s efforts to keep pace. We have a process for evaluating the profitability of our branches and other office and operational facilities. The identification of unprofitable operations and facilities can lead to restructuring charges and introduce the risk of disruptions to revenues and customer relationships.

Our financial condition and results of operations have been adversely affected, and may continue to be adversely affected, by the U.S. and international financial market and economic conditions.

We have been, and continue to be, impacted by general business and economic conditions in the United States and, to a lesser extent, abroad. These conditions include short-term and long-term interest rates, inflation, money supply, political issues, legislative and regulatory changes, fluctuations in both debt and equity capital markets, broad trends in industry and finance, unemployment and investor confidence, all of which are beyond our control. Although there has been gradual improvement in the U.S. economy over the past decade, deterioration in any of these conditions could result in increases in loan delinquencies and non-performing assets, decreases in loan collateral values, the value of our investment portfolio and demand for our products and services. Higher credit or collateral related losses, or decreases in the value of our investment portfolio or demand for our products and services, could negatively impact our financial condition or results of operations.

15

Prepayments of loans may negatively impact our business.

Generally, our customers may prepay the principal amount of their outstanding loans at any time, frequently without financial penalty to the borrower. The speeds at which such prepayments occur, as well as the size of such prepayments, are within our customers’ discretion. Fluctuations in interest rates, in certain circumstances, may also lead to high levels of loan prepayments. If customers prepay the principal amount of their loans, and we are unable to lend those funds to other borrowers or invest the funds at the same or higher interest rates, interest income will be reduced. A significant reduction in interest income could have a negative impact on our results of operations and financial condition.

We may become involved in lawsuits and legal proceedings that may lead to adverse consequences.

As a participant in the financial services industry, many aspects of the Company’s business involve substantial risk of legal liability. From time to time, we are named or threatened to be named as defendants in various lawsuits, including class actions, arising from our business activities. In addition, when other financial institutions receive adverse judgments in litigation or

agree to settlements, that may encourage plaintiffs and their attorneys to bring and maintain claims, including class actions,

against other financial institutions, including the Company. There is no assurance that litigation with private parties will not increase in the future. Future actions against us may result in judgments, settlements, fines, penalties or other results adverse to us, which could materially adversely affect our business, financial condition or results of operations, or cause serious reputational harm to us. Although we maintain insurance, the scope of this coverage may not provide us with full, or even partial, coverage in any particular case. As a result, a judgment against us in any such litigation and/or legal costs incurred in defending us against such litigation could have a material adverse effect on our financial condition and results of operation.

We may incur fines, penalties and other negative consequences from regulatory violations, possibly even inadvertent or unintentional violations.

The financial services industry is subject to intense scrutiny from bank supervisors in the examination process and aggressive enforcement of federal and state regulations, particularly with respect to mortgage-related practices and other consumer compliance matters, and compliance with AML, BSA and OFAC regulations, and economic sanctions against certain foreign countries and nationals. Enforcement actions may be initiated for violations of laws and regulations and unsafe or unsound practices. In addition, some legal/regulatory frameworks provide for the imposition of fines or penalties for noncompliance even though the noncompliance was inadvertent or unintentional and even though there were systems and procedures designed to ensure compliance in place at the time. There have been a number of significant enforcement actions in recent years by regulators, state attorneys general and the Department of Justice against banks and other non-bank financial institutions with respect to AML and sanctions laws, and some have resulted in substantial penalties including criminal pleas. Although the Company and the Bank have adopted policies and procedures designed to comply with these laws, any failure to comply with these laws and other regulations, or to maintain an adequate compliance program, could result in significant fines, penalties, lawsuits, regulatory sanctions, reputational damage, or restrictions on our business.

We are subject to numerous laws designed to meet the credit needs of low- and moderate-income communities and to protect consumers, including the Community Reinvestment Act and fair lending laws, and failure to comply with these laws could lead to a wide variety of sanctions.

The Community Reinvestment Act, the Equal Credit Opportunity Act, the Fair Housing Act and other fair lending laws and regulations impose community investment and nondiscriminatory lending requirements on financial institutions. The FRB, OCC, CFPB, the Department of Justice and other federal agencies are responsible for enforcing these laws and regulations. A successful regulatory challenge to an institution’s performance under the Community Reinvestment Act, the Equal Credit Opportunity Act, the Fair Housing Act or other fair lending laws and regulations could result in a wide variety of sanctions, including damages and civil money penalties, injunctive relief, restrictions on mergers and acquisitions, restrictions on expansion and restrictions on entering new business lines. Private parties may also have the ability to challenge an institution’s performance under fair lending laws in private class action litigation. Such actions could have a material adverse effect on our business, financial condition and results of operations.

Damage to our reputation could significantly harm our business.

We are dependent on our reputation within our market area, as a trusted and responsible financial company, for all aspects of our relationships with customers, employees, vendors, third-party service providers and others with whom we conduct business or potential future business, particularly because our business is primarily concentrated in certain areas of Maine. Our actual or perceived failure to (i) identify and address potential conflicts of interest, ethical issues, money-laundering, or privacy issues; (ii) meet legal and regulatory requirements applicable to the Bank and to the Company; (iii) maintain the privacy of

16

customer and accompanying personal information; (iv) maintain adequate record keeping; (v) engage in proper sales and trading practices; and (vi) identify the legal, reputational, credit, liquidity and market risks inherent in our products; or any action of one of our employees that results in actual or perceived misconduct or error, among other things, could give rise to reputational risk that could cause harm to the Bank and our business prospects. If we fail to address any of these issues in an appropriate manner, we could be subject to additional legal risks, which, in turn, could increase the size and number of litigation claims and damages asserted or subject us to enforcement actions, fines and penalties and cause us to incur related costs and expenses. Because we primarily serve individuals and businesses located in Maine, any negative impact resulting from reputational harm, including any impact on our ability to attract and retain customers and employees, likely would be greater than if our business were more geographically diverse. Moreover, the advent and expansion of social media creates the potential for rapid and widespread dissemination of information, including inaccurate, misleading, or false information, that could damage our reputation and affect our ability to attract and retain customers and employees.

We may incur significant losses as a result of ineffective risk management processes and strategies.

We seek to monitor and control our risk exposure through a risk and control framework encompassing a variety of separate but complementary financial, credit, operational, compliance and legal reporting systems, internal controls, management review processes and other mechanisms. While we employ a broad and diversified set of risk monitoring and risk mitigation techniques, those techniques and the judgments that accompany their application may not be effective and may not anticipate every economic and financial outcome in all market environments or the specifics and timing of such outcomes. Market conditions over the last several years have involved unprecedented dislocations and highlight the limitations inherent in using historical data to manage risk. If our risk and control framework, or the assumptions underlying our framework, prove ineffective, we may not be able to mitigate our risk exposures effectively, and, as a result, we could incur litigation, negative regulatory consequences, reputational damage or other adverse consequences, and we could suffer unexpected losses that may affect our business, financial condition or results of operations.

Our business may be adversely affected if we are unable to attract and retain qualified employees.

The Company’s employees are its most important resource, and in many areas of the financial services industry, competition for qualified personnel is intense. If the Company provides inadequate succession planning, or is unable to continue to retain and attract qualified employees, this could result in a material adverse effect on the Company’s performance, including its competitive position.

We could be held responsible for environmental liabilities of properties we acquired through foreclosure.

In the course of business, we may acquire, through foreclosure, properties securing loans originated or purchased that are in default. Particularly in commercial real estate lending, there is a risk that material environmental violations could be discovered on these properties. In this event, we might be required to remedy these violations at the affected properties at our sole cost and expense. The cost of remedial action could substantially exceed the value of affected properties. We may not have adequate remedies against the prior owner or other responsible parties and could find it difficult or impossible to sell the affected properties. These events could have an adverse effect on our financial condition and results of operations.

Systems failures, interruptions or breaches of security concerning ourinformation base, including the information we maintain relating to our customers, could have an adverse effect on our financial condition and results of operations.

In the ordinary course of business, we rely on electronic communications and information systems to conduct our business and to store sensitive data, including financial information regarding customers. We are subject to certain operational risks, including, but not limited to, data processing system failures and errors, inadequate or failed internal processes, customer or employee fraud, cyberattacks, hacking, identity theft and catastrophic failures resulting from terrorist acts or natural disasters. We depend upon data processing, software, communication, and information exchange on a variety of computing platforms and networks and over the internet, and we rely on the services of a variety of vendors to meet our data processing and communication needs. Despite instituted safeguards, we cannot be certain that all of our systems are entirely free from vulnerability to attack or other technological difficulties or failures. If information security is breached or other technology difficulties or failures occur, information may be lost or misappropriated, services and operations may be interrupted and we could be exposed to claims from customers. While we maintain a system of internal controls and procedures, any of these results could have a material adverse effect on our reputation, business, financial condition, results of operations or liquidity.

We regularly assess and test our security systems and disaster preparedness, including back-up systems, but the risks are substantially escalating. As a result, cybersecurity and the continued enhancement of our controls and processes to protect our systems, data and networks from attacks, unauthorized access or significant damage remain a priority. We have expended

17

substantial resources to protect our systems, and may be required to expend significant additional resources to modify our protective measures or to investigate and remediate vulnerabilities or other exposures in our computer systems and networks, and we may be subject to litigation and financial losses that are either not insured against or not fully covered through insurance maintained by us. Any such losses, which may be difficult to detect, could adversely affect our financial condition or results of operations. In addition, the occurrence of such a loss could expose the Company and the Bank to reputational risk, the loss of customers and additional regulatory scrutiny.

We are subject to a variety of cybersecurity risks that, if realized, could adversely affect our business, financial condition and results of operations.

Information security risks for financial institutions such as the Company and the Bank have increased significantly in recent years due to the use of online, telephone and mobile banking channels by customers and the increased sophistication and activities of organized crime, hackers, terrorists and other external parties. Third parties with whom we or our customers do business also present operational and information security risks to us, including security breaches or failures of their own systems. Our operations rely on the secure processing, transmission and storage of confidential information in our computer systems and networks. Our businesses rely on our digital technologies, computer and email systems, software, and networks to conduct their operations. Our technologies, systems, networks and our customers’ devices are periodically the target of cyberattacks, and may be the target of future cyberattacks, including through the introduction of computer viruses, and/or malicious code, or by means of phishing attacks, social engineering or other information security breaches. Malicious actors may also attempt to fraudulently induce employees, customers or other users of our systems to disclose sensitive information, including passwords and other identifying information, in order to gain access to data or our systems.

In recent years, there have been several well-publicized attacks on various companies, including in the financial services industry, and personal, proprietary, and public e-mail systems in which the perpetrators gained unauthorized access to confidential information and customer data, often through the introduction of computer viruses or malware, cyberattacks, phishing, or other means. Even if not directed at the Company or the Bank specifically, attacks on other entities with whom we do business or on whom we otherwise rely or attacks on financial or other institutions important to the overall functioning of the financial system could adversely affect, directly or indirectly, aspects of our business.

Furthermore, as cyber threats continue to evolve, we may be required to expend significant additional resources to continue to modify or enhance our systems or to investigate and remediate vulnerabilities. System enhancements and updates may also create risks associated with implementing and integrating new systems. Due to the complexity and interconnectedness of information technology systems, the process of enhancing our systems can itself create a risk of systems disruptions and security issues.

Although we believe we have appropriate information security controls and procedures, we may not be able to anticipate, detect, or implement effective preventative measures against all potential threats, particularly because the techniques used by cyber criminals change frequently, often are not recognized until launched and can be initiated from a variety of sources. In the event one or more of the events described above occurs, this could result in the unauthorized release, gathering, monitoring, misuse, loss or destruction of our or our customers’ confidential, proprietary and other information, the theft of customer assets through fraudulent transactions or disruption of our or our customers’ or other third parties’ business operations, which could result in legal or regulatory action, significant losses, increased compliance costs or reputational damage, any of which could adversely affect our business, financial condition or results of operations.

We must adapt to information technology changes in the financial services industry, which could present operational issues, require significant capital spending, or impact our reputation.

The financial services industry is constantly undergoing technological changes, with frequent introductions of new technology-driven products and services. We invest significant resources in information technology system enhancements in order to provide functionality and security at an appropriate level. The effective use of technology increases efficiency and enables financial institutions to better serve customers and reduce costs. Our future success will depend, in part, upon our ability to address the needs of our customers by using technology to provide products and services that will satisfy customer demands for convenience, as well as to create additional efficiencies in our operations. We may not be able to effectively implement new technology-driven products and services or be successful in marketing these products and services to our customers. Failure to successfully implement and integrate future system enhancements could adversely impact the ability to provide timely and accurate financial information in compliance with legal and regulatory requirements, which could result in sanctions from regulatory authorities. Such sanctions could include fines and suspension of trading in our stock, among others. In addition, future system enhancements could have higher than expected costs and/or result in operating inefficiencies, which could increase the costs associated with the implementation as well as ongoing operations.

18

Failure to properly utilize system enhancements that are implemented in the future could result in impairment charges that adversely impact our financial condition and results of operations and could result in significant costs to remediate or replace the defective components. In addition, we may incur significant training, licensing, maintenance, consulting and amortization expenses during and after systems implementations, and any such costs may continue for an extended period of time.

We rely on other companies to provide key components of our business infrastructure.

Third party vendors provide key components of our business infrastructure such as internet connections, network access and core application processing. While we have selected these third party vendors carefully, we do not control their actions. Any problems caused by these third parties, including as a result of their not providing us their services for any reason or their performing their services poorly, could adversely affect our ability to deliver products and services to our customers or otherwise conduct our business efficiently and effectively. Replacing these third party vendors could also entail significant delay and expense.

Third parties with which we do business could also be sources of information security risk to us, including from breakdowns, systems failures or cyber threats through their systems to our systems. Any of these occurrences could impact our ability to operate our business, or cause financial loss, potential liability to clients, reputational damage or regulatory consequences, any of which could have a material adverse effect on our financial condition or results of operations.

Natural disasters, acts of terrorism and other external events could harm our business.

Natural disasters can disrupt our operations, result in damage to our properties, reduce or destroy the value of the collateral for our loans and negatively affect the economies in which we operate, which could have a material adverse effect on our results of operations and financial condition. A significant natural disaster, such as a tornado, hurricane, earthquake, fire or flood, could have a material adverse impact on our ability to conduct business, and our insurance coverage may be insufficient to compensate for losses that may occur. Because we primarily serve individuals and businesses located in Maine, a natural disaster likely would have a greater impact on our business, operations and financial condition than if our business were more geographically diverse. Acts of terrorism, war, civil unrest, violence or human error could cause disruptions to our business or the economy as a whole. While we have established and regularly test disaster recovery procedures, the occurrence of any such event could have a material adverse effect on our business, operations and financial condition.

In addition, there have been reports that the recent coronavirus outbreak which originated in China, has significantly impacted other countries, including disrupting or restricting supply chains, which has resulted in closures of facilities and reduction in demand across companies in a variety of industries. Recent developments and reports relating to the coronavirus have coincided with heightened volatility in financial markets in the U.S. and globally. If the coronavirus affects (i) the ability of our borrowers to satisfy their obligations; (ii) the demand for our products and services; (iii) causes our business to be interrupted; and/or (iv) leads to a significant or sustained impact on global markets or economic growth, our business, operations and financial condition could be adversely affected.

Camden National Wealth Management may be negatively affected by changes in economic and market conditions.

A substantial portion of income from fiduciary services is dependent on the market value of wealth management assets under administration, which are primarily marketable securities. Changes in domestic and foreign economic conditions, volatility in financial markets, and general trends in business and finance, all of which are beyond our control, could adversely impact the market value of these assets and the fee revenues derived from the management of these assets. For example, the uncertainty surrounding the terms of the U.K.’s exit from the European Union (“EU”), or Brexit, could negatively impact markets and cause weaker macroeconomic conditions that extend beyond the U.K. and the EU that could continue for the foreseeable future.

Due to strong competition, Camden National Wealth Management may not be able to attract and retain clients at current levels. Competition is strong as there are numerous well-established and successful investment management and wealth advisory firms including commercial banks and trust companies, investment advisory firms, mutual fund companies, stock brokerage firms, and other financial companies. Our ability to attract and retain wealth management clients is dependent upon our ability to compete with competitors’ investment products, level of investment performance, client services, and marketing and distribution capabilities. If we are not successful, our results of operations and financial condition may be negatively impacted.

19

If we do not maintain net income growth, the market price of our common stock could be adversely affected.

Return on shareholders’ equity and other measures of profitability, which affect the market price of our common stock, depend in part on continued growth and expansion. Our growth strategy has two principal components: internal growth and external growth. The ability to generate internal growth is affected by the competitive factors described herein as well as by the primarily rural characteristics and related demographic features of the markets we serve. The ability to continue to identify and invest in suitable acquisition candidates on acceptable terms is an important component of our external growth strategy. In pursuing acquisition opportunities, we may be in competition with other companies having similar growth strategies. As a result, we may not be able to identify or acquire promising acquisition candidates on acceptable terms. Competition for these acquisitions could result in increased acquisition prices and a diminished pool of acquisition opportunities. An inability to find suitable acquisition candidates at reasonable prices could slow our growth rate and have a negative effect on the market price of our common stock.

Our financial statements are based in part on assumptions and estimates, which, if wrong, could cause unexpected losses in the future.

Pursuant to U.S. generally accepted accounting principles, we are required to use certain assumptions and estimates in preparing our financial statements, including in determining credit loss reserves, reserves related to litigation and the fair value of certain assets and liabilities, among other items. If assumptions or estimates underlying our financial statements are incorrect, we may experience material losses. For additional information, see Item 7. "Management’s Discussion and Analysis of Financial Condition and Results of Operations—Critical Accounting Policies."

We may be required to write down goodwill and other identifiable intangible assets.

When we acquire a business, a portion of the purchase price of the acquisition may be allocated to goodwill and other identifiable intangible assets. The excess of the purchase price over the fair value of the net identifiable tangible and intangible assets acquired determines the amount of the purchase price that is allocated to goodwill. At December 31, 2019, our goodwill and other identifiable intangible assets totaled $98.2 million. Under current accounting standards, if we determine goodwill or intangible assets are impaired, we would be required to write down the value of these assets to fair value. We conduct an annual review, or more frequently if events or circumstances warrant such additional review, to determine whether goodwill is impaired. We recently completed our goodwill impairment analysis as of November 30, 2019 and concluded goodwill was not impaired. We conduct a review of our other intangible assets for impairment should events or circumstances warrant such review. There were no triggers for such review for impairment for other intangible assets for the year ended December 31, 2019. We cannot provide assurance that we will not be required to take an impairment charge in the future. Any impairment charge would have a negative effect on our shareholders’ equity and financial results and may cause a decline in our stock price.

Continued market volatility may impact our business and the value of our common stock.

Our business performance and the trading price of shares of our common stock may be affected by many factors affecting financial institutions, including volatility in the credit, mortgage and housing markets, the markets for securities relating to mortgages or housing, and the value of debt and mortgage-backed and other securities that we hold in our investment portfolio. Government action and legislation may also impact us and the value of our common stock. We cannot predict what impact, if any, volatility will have on our business or share price and for these and other reasons our shares of common stock may trade at a price lower than that at which they were purchased.

We are a holding company and dependent upon our subsidiary for dividends, distributions and other payments.

We are a legal entity separate and distinct from our direct and indirect subsidiaries. Our revenue (on a parent-only basis) is derived primarily from interest and dividends paid to us by the Bank. Our right, and consequently the right of our shareholders, to participate in any distribution of the assets or earnings of the Bank through the payment of such dividends or otherwise is necessarily subject to the prior claims of creditors of the Bank (including depositors), except to the extent that certain claims of us in a creditor capacity may be recognized.

Holders of our common stock are entitled to receive dividends only when, and if declared by our Board of Directors. Although we have historically declared cash dividends on our common stock, we are not required to do so and our Board of Directors may reduce or eliminate our common stock dividend in the future. The FRB has authority to prohibit bank holding companies from paying dividends if such payment is deemed to be an unsafe or unsound practice. Additionally, the OCC has the authority to use its enforcement powers to prohibit a bank from paying dividends if, in its opinion, the payment of dividends would constitute an unsafe or unsound practice. Further, our ability to pay dividends would be restricted under current

20

regulatory capital rules if we do not maintain a capital conservation buffer. A reduction or elimination of dividends could adversely affect the market price of our common stock. See Item 1. “Business—Supervision and Regulation—Dividend Restrictions” and “Business—Supervision and Regulation—Regulatory Capital Requirements.”

Reforms to London Interbank Offered Rate ("LIBOR") and other indices, and related uncertainty, may adversely affect our business, financial condition or results of operations.

In July 2017, the U.K. Financial Conduct Authority announced that after 2021 it will no longer persuade or require banks to submit rates for LIBOR. This announcement, and, more generally, financial benchmark reforms and changes in the interbank lending markets, have resulted in uncertainty about the future of LIBOR and certain other rates or indices that are used as interest rate benchmarks. These actions may result in future changes in the rules or methodologies used to calculate benchmarks or in the discontinuance or unavailability of certain benchmarks. The possible impact of these actions is uncertain and cannot be predicted at this time, and the potential or actual discontinuance of benchmark quotes may have a material, adverse effect on the value of, return on and trading market for our financial assets and liabilities that are based on or are linked to benchmarks, including our hedge contracts, or our financial condition or results of operations. In addition, we cannot assure that we and other market participants will adequately be prepared for a discontinuation of LIBOR or other benchmarks, and such discontinuation may have an unpredictable impact on our contracts and/or cause significant disruption to financial markets that are relevant to our business, which may have a material, adverse effect on our financial condition or results of operations.

Risks Arising From the Legal and Regulatory Framework in which Our Business Operates

Our banking business is highly regulated, and we may be adversely affected by changes in law and regulation.

We are subject to regulation and supervision by the FRB, and the Bank is subject to regulation and supervision by the OCC and the FDIC, as well as regulations issued by the CFPB. Federal laws and regulations govern numerous matters affecting us, including changes in the ownership or control of banks and bank holding companies, maintenance of adequate capital and the financial condition of a financial institution, permissible types, amounts and terms of extensions of credit and investments, permissible nonbanking activities, the level of reserves against deposits and restrictions on dividend payments. The OCC possesses the power to issue cease and desist orders to prevent or remedy unsafe or unsound practices or violations of law by banks subject to their regulation, and the FRB possesses similar powers with respect to bank holding companies. These and other restrictions limit the manner in which we may conduct business and obtain financing.

Our business is highly regulated and the laws, rules, regulations, and supervisory guidance and policies applicable to us are subject to regular modification and change, and there have been significant revisions to the laws and regulations applicable to banks and bank holding companies that have been enacted or proposed in recent years. Changes to statutes, regulations, or regulatory policies, including changes in interpretation or implementation of statutes, regulations, or policies, have and could in the future subject us to additional costs, limit the types of financial services and products we may offer, and/or increase the ability of non-banks to offer competing financial services and products, among other things. Failure to comply with laws, regulations, policies or supervisory guidance could result in enforcement and other legal actions by federal or state authorities, including criminal and civil penalties, the loss of FDIC insurance, revocation of a banking charter, other sanctions by regulatory agencies, civil money penalties, and/or reputational damage, which could have a material adverse effect on our business, financial condition, and results of operations. See Item 1. “Business-Supervision and Regulation.”

We are required to maintain sufficient capital and adequate liquidity.

As a banking organization, our capital and liquidity are subject to regulation and supervision by banking regulators. We are required to maintain minimum levels of capital. In addition, our banking regulators could require us to maintain more and higher quality capital than previously expected. Our banking regulators could also require us to hold higher levels of short-term investments, thereby limiting our ability to invest in longer-term or less liquid assets at higher yields. The need to maintain capital and liquidity could result in our being required to take steps to increase our regulatory capital and may dilute shareholder value or limit our ability to pay dividends or otherwise return capital to our investors through stock repurchases. In addition, if we fail to maintain appropriate levels of capital or liquidity, we could become subject to formal or informal enforcement actions that may impose restrictions on our business, including limiting our lending activities or our ability to expand, requiring us to raise additional capital (which may be dilutive to shareholders) or requiring regulatory approval to pay dividends or otherwise return capital to shareholders. See Item 1. “Business-Supervision and Regulation-Regulatory Capital Requirements” for additional information on capital requirements applicable to us and the Bank.

21

Changes in accounting standards can be difficult to predict and can materially impact how we record and report our financial condition and results of operations.

Our accounting policies and methods are fundamental to how we record and report our financial condition and results of operations. From time to time, the FASB and the SEC change the financial accounting and reporting standards that govern the preparation of our financial statements. These changes can be hard to anticipate and implement and can materially impact how we record and report our financial condition and results of operations. For example, we implemented FASB’s guidance on the measurement of credit losses (ASU 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments), commonly known as “CECL,” effective as of January 1, 2020. CECL introduces a forward-looking “expected loss” model to estimate credit losses, rather than the “incurred loss” model previously required under GAAP. CECL substantially changes how we calculate our allowance for credit losses. See Note 1 to our financial statements, Business and Summary of Significant Accounting Changes and Item 7. "Management's Discussion and Analysis of Financial Condition and Results of Operations—Critical Accounting Policies" for additional information on CECL and its impact on our financial reporting. Other future changes in accounting standards could materially impact how we report our financial condition, and we cannot predict whether such standards will be adopted or their resultant impact.

Changes in tax laws and regulations and differences in interpretation of tax laws and regulations may adversely impact our financial statements.

Local, state or federal tax authorities may interpret tax laws and regulations differently than we do and challenge tax positions that we have taken on tax returns. This may result in differences in the treatment of revenues, deductions, credits and/or differences in the timing of these items. The differences in treatment may result in payment of additional taxes, interest or penalties that could have a material adverse effect on our results. In addition, there may be future changes to tax laws, administrative rulings or court decisions that could adversely affect our financial condition, including an increased provision for income taxes and/or reduced net income. We are not able to predict the timing or impact of any changes in local, state or federal tax laws.

(2) Includes space leased to third parties.

For additional information regarding the Company's premises and equipment and lease obligations see Notes 5 and 6 of the consolidated financial statementswithin Item 8. Financial Statements and Supplementary Data.

Item 3. Legal Proceedings

The Company is currently involved, and from time to time in the future may become involved, in various legal claims that arise in the normal course of the Company’s business. The Company may also in the future become involved in other regulatory, judicial and/or arbitration proceedings relating to matters that arise in connection with the conduct of the Company’s business. Because of the difficulty in predicting the outcome of these matters, particularly when they are in their early stages, the Company cannot predict what the final outcome of each legal proceeding may be, or what the eventual loss, fine or penalty related to each proceeding may be, if any. Based on currently available information, in our opinion the results of legal proceedings that are currently pending are not expected to have a material effect on our 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. 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. As of December 31, 2019 and 2018, the Company did not maintain material reserves against legal claims.

Item 4. Mine Safety Disclosures

Not applicable.

Item 5. Market for Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities

The Company’s common stock is currently traded on the NASDAQ Global Market (“NASDAQ”) under the ticker symbol “CAC.” The Company has paid quarterly dividends since its foundation in 1984. The high and low closing sales prices (as quoted by NASDAQ for 2019 and 2018) and cash dividends declared per share of the Company’s common stock, by calendar quarter for the past two years, were as follows:

	2019						2018
	Market Price				Dividends Declared per Share		Market Price				Dividends Declared per Share
	High		Low				High		Low
First Quarter	$	45.72	$	35.94	$	0.30	$	45.74	$	41.91	$	0.25
Second Quarter	46.95		41.79		0.30		47.43		43.54		0.30
Third Quarter	45.57		40.40		0.30		47.05		42.58		0.30
Fourth Quarter	46.82		41.89		0.33		42.23		34.05		0.30

As of February 24, 2020, there were 15,148,441 shares of the Company’s common stock outstanding by approximately 1,100 shareholders, as obtained through our transfer agent. Such number of shareholders does not reflect the number of persons or entities holding stock in nominee name through banks, brokerage firms and other nominees.

Although the Company has historically paid quarterly dividends on its common stock, the Company’s ability to pay such dividends depends on a number of factors, including restrictions under federal laws and regulations on the Company’s ability to pay dividends, and as a result, there can be no assurance that dividends will be paid in the future. For further information on dividend restrictions, refer to Item 1. "Business—Supervision and Regulation" and Item 7. "Management’s Discussion and Analysis of Financial Condition and Results of Operations—Capital Resources."

The following graph illustrates the annual percentage change in the cumulative total shareholder return of the Company’s common stock for the period December 31, 2014 through December 31, 2019. For purposes of comparison, the graph illustrates comparable shareholder returns of the SNL $1B – $5B Bank Index and the Russell 2000 Stock Index. The graph assumes a $100 investment on December 31, 2014 in each case and measures the amount by which the market value, assuming reinvestment of dividends, has changed as of December 31, 2019.

NON-GAAP FINANCIAL MEASURES AND RECONCILIATION TO GAAP

In addition to evaluating the Company’s results of operations in accordance with GAAP, management supplements this evaluation with an analysis of certain non-GAAP financial measures, such as return on average tangible equity; the efficiency ratio; tax equivalent net interest income; tangible book value per share; tangible common equity ratio; and core deposits and average core deposits. We utilize these non-GAAP financial measures for purposes of measuring our performance against our peer group and other financial institutions and analyzing our internal performance. We also believe these non-GAAP financial measures help investors better understand the Company’s operating performance and trends and allow for better performance comparisons to other banks. In addition, these non-GAAP financial measures remove the impact of unusual items that may obscure trends in the Company’s underlying performance. These disclosures should not be viewed as a substitute for GAAP operating results, nor are they necessarily comparable to non-GAAP performance measures that may be presented by other financial institutions.

Return on Average Tangible Equity. The following table provides a reconciliation of return on average equity to return on average tangible equity. Return on average equity and return on average tangible equity represent a shareholders' return on capital and tangible capital, respectively, deployed in our business and is a common measure by financial institutions.

Efficiency Ratio. The efficiency ratio represents an approximate measure of the cost required for the Company to generate a dollar of revenue. This is a common measure used by financial institutions and is a key ratio for evaluating Company performance. The efficiency ratio is calculated as the ratio of (i) total non-interest expense, adjusted for certain operating expenses to (ii) net interest income on a tax equivalent basis plus total non-interest income, adjusted for certain other income items.

Tangible Book Value per Share and Tangible Common Equity Ratio. Tangible book value per share is the ratio of (i) shareholders’ equity less goodwill, premium on deposits and other acquisition-related intangibles to (ii) total common shares outstanding at period end. Tangible book value per share is a common measure within our industry when assessing the value of a company as it removes goodwill and other intangible assets generated within purchase accounting upon a business combination.

Tangible common equity is the ratio of (i) shareholders’ equity less goodwill and other intangible assets to (ii) total assets less goodwill and other intangible assets. This ratio is a measure used within our industry to assess whether or not a company is highly leveraged.

CRITICAL ACCOUNTING POLICIES

Critical accounting policies are defined as those that are reflective of significant judgments and uncertainties, and could potentially result in materially different results under different assumptions and conditions. In preparing the Company’s consolidated financial statements, management is required to make significant estimates and assumptions that affect assets, liabilities, revenues, and expenses reported. Actual results could materially differ from our current estimates, as a result of changing conditions and future events. Several estimates are particularly critical and are susceptible to significant near-term change, including (i) the ALL; (ii) accounting for acquisitions and the subsequent review of goodwill and intangible assets generated in an acquisition for impairment; (iii) OTTI of investments; (iv) income taxes; and (v) accounting for defined benefit and postretirement plans.

Refer to Note 1 of the consolidated financial statements for additional details of the Company's accounting policies, including new accounting standards recently adopted and those yet to be adopted.

Allowance for Loan Losses. Management is committed to maintaining an ALL that is appropriate to absorb likely loss exposure in the loan portfolio. Evaluating the appropriateness of the ALL is a key management function and one that requires the most significant amount of management estimates and assumptions. The ALL, which is established through a charge to the provision for credit losses, consists of two components: (i) a reduction to total gross loans in the asset section of the consolidated statements of condition, and (ii) the reserve for unfunded commitments included in other liabilities on the consolidated statements of condition. We regularly evaluate the ALL for adequacy by taking into consideration, among other factors, historical trends in charge-offs and delinquencies, overall risk characteristics and size of the portfolios, ongoing review of significant individual loans, trends in levels of watched or criticized assets, business and economic conditions, regulatory guidance, and other relevant factors.

In determining the appropriate level of ALL, we use a methodology to systematically measure the amount of estimated loan loss exposure inherent in the loan portfolio. The methodology focuses on three key elements: (i) identification of loss allocations for specific loans, (ii) loss allocation factors for certain loan types based on credit grade and loss experience, and (iii) general loss allocations for other qualitative and environmental factors.

Loans for which a specific loss allocation may be required are identified and assessed at least quarterly by reviewing individual loans with an outstanding principal balance of $500,000 or more that are risk rated as substandard or doubtful and are on non-accrual status in accordance with our internal policy. We believe loans that meet the above criteria most often demonstrate the qualities and characteristics of an impaired loan and are individually significant enough to the Company to warrant individual assessment. Once a loan is deemed to be impaired, an allowance may be established to reduce its net carrying value to its estimated value, if the estimated value of an impaired loan is lower than its recorded investment. The estimated value of an impaired loan is determined using one of three methods: (i) calculating the present value of expected future cash flows discounted at the loan's effective interest rate (i.e. discounted cash flow method); (ii) the loan's observable market price; or (iii) the fair value of the collateral if the loan is collateral dependent and repayment of the loan is expected to be provided solely by the underlying collateral.

The remaining loan portfolio is separated into risk pools by portfolio segment and subject to a general reserve factor. At least annually, we reassess and revise the loss allocation factor used in constructing the reserve for each risk pool. The factors we consider in constructing each risk pool include: (i) risk rating; (ii) historical losses; (iii) market conditions; and (iv) other economic factors.

In assessing the risk rating of a particular loan, we consider, 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 a 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 currently an explicit part of our methodology, could impact the risk rating assigned to that loan.

Three times a year, management conducts a thorough review of adversely risk rated commercial and commercial real estate exposures exceeding certain thresholds to re-evaluate the risk rating and identify impaired loans. This extensive review takes into account the obligor’s repayment history and financial condition, collateral value, guarantor support, local economic and industry trends, and other factors relevant to the particular loan relationship.

31

Because the methodology is based upon historical experience and trends, and significant judgments, there are factors that may arise that result in different estimations. Significant factors that could give rise to changes in these estimates may include, but are not limited to, changes in economic conditions in our market area, concentration of risk, declines in local property values, and the results of regulatory examinations. As of December 31, 2019, the recorded ALL of $25.2 million represents our best estimate, however, under adversely different conditions or assumptions the ALL may need to be increased. The ALL is reviewed on a monthly basis to assess recent asset quality trends and impact on the Company's financial condition. The ALL is reviewed and approved on a quarterly basis at each of the Bank's Board of Directors meetings.

The Company will adopt the new accounting standard for credit losses, ASU No. 2016-13, Financial Instruments - Credit Losses(Topic 326):Measurement of Credit Losses on Financial Instruments, as amended, effective January 1, 2020. This new accounting standard, commonly referred to as "CECL," significantly changes the Company's accounting for reserves on loans, unfunded loan commitments, and certain guarantees, as well as introduces the consideration for establishment of a reserve on HTM investments. Under CECL, companies are required to estimate future credit losses over the contractual life of certain assets, adjusted for expected prepayments, including homogeneous pools of loans and HTM investments, as well as establish reserves for unfunded loan commitments and certain guarantees.

CECL became effective for the Company on January 1, 2020. The initial adjustment will not be reported in net income, but as a cumulative-effect adjustment to retained earnings. We have worked steadily over the past several years in anticipation of our implementation of CECL, which included: (i) the creation of an internal project team comprised of members from Credit Risk, Accounting, Treasury, Operations, Information Technology and Internal Audit; (ii) engaging third party consultants to assist with internal data validation, CECL software implementation, review of the control framework design, including review and changes to our overall governance structure for CECL oversight, and other general consultative matters; and (iii) performing parallel calculations and analyzing differences between today’s incurred model and CECL.

The Company has performed a parallel calculation as of December 31, 2019 and is in the process of finalizing its calculation, internal CECL policy and internal controls framework. Based on our fourth quarter parallel calculation, we believe that the adoption of CECL will result in an immaterial impact to the Company’s retained earnings and the Company and Bank’s regulatory capital ratios as of January 1, 2020. The Company and Bank will continue to exceed regulatory guidelines, and the Bank's capital ratios will meet the requirements for it to be considered "well capitalized" under prompt correct action. As such, the Company does not anticipate adopting the transition relief provided by the regulatory agencies for regulatory capital purposes.

The Company expects that CECL may create more volatility in the level of allowance for credit losses from quarter to quarter as changes in the level of allowance for credit losses will be dependent upon, among other things, macroeconomic forecasts and conditions, loan portfolio volumes and credit quality.

Refer to Note 1 of the consolidated financial statements for further details on CECL.

Purchase Price Allocation and Impairment of Goodwill and Identifiable Intangible Assets. We record all acquired assets and liabilities at fair value, which is an estimate determined by the use of internal valuation techniques. We also may engage external valuation services to assist with the valuation of material assets and liabilities acquired, including, but not limited to, loans, core deposit intangibles and/or other intangible assets, real estate and time deposits. As part of purchase accounting, we typically acquire goodwill and other intangible assets as part of the purchase price. These assets are subject to ongoing periodic impairment tests under differing accounting models. We did not acquire any other company or assets for the year ended December 31, 2019 or 2018.

Goodwill impairment evaluations are required to be performed at least annually, but may be required more frequently if certain conditions indicate a potential impairment may exist. Our policy is to perform the goodwill impairment analysis annually as of November 30^th, or more frequently as warranted. The goodwill impairment evaluation is required to be performed at the reporting unit level and is performed using the two-step process outlined in ASC 350-20, Goodwill ("ASC 350-20").

As of November 30, 2019, we assessed goodwill for impairment at the consolidated Company-level as the Company's operating segment was also its only reporting unit. We used the qualitative analysis (i.e. "step zero") outlined in ASC 350-20 to test goodwill for impairment, and considered such factors as the macroeconomic environment; overall industry environment and performance; company specific factors, including, but not limited to, competition, performance and personnel. Through completion of our analysis, we concluded it was not more-likely-than-not that the Company's carrying value exceeded its fair value. Thus, no further goodwill impairment analysis was warranted and we concluded that goodwill was not impaired as of

32

November 30, 2019. Furthermore, we are not aware of any indications and/or triggers subsequent to our goodwill impairment analysis performed as of November 30, 2019 that would lead us to believe there may be subsequent impairment of goodwill.

For the year ended December 31, 2018 and 2017, we assessed goodwill for impairment and concluded goodwill was not impaired.

Effective January 1, 2020, the Company adopted ASU No. 2017-04, Intangibles - Goodwill and Other (Topic 350):Simplifying the Test for Goodwill Impairment, which eliminates the performance of "Step 2" of the goodwill impairment analysis. Thus, should the carrying value of a reporting unit exceed its fair value, "Step 1", the reporting unit is impaired and goodwill is written down by the amount the reporting unit's carrying value exceeds its fair value. Refer to Note 1 of the consolidated financial statements for an overview of "Step 1" and "Step 2" of the goodwill impairment analysis.

Core deposit intangible assets have a finite life and are amortized over their estimated useful lives. Core deposit intangible assets are subject to impairment tests if events or circumstances indicate a possible inability to realize the carrying amount. Core deposit intangible assets are measured for impairment utilizing a cost recovery model. We did not identify any events or circumstances that occurred for the year ended December 31, 2019 or 2018 that would indicate that our core deposit intangible assets may be impaired and should be evaluated for such.

OTTI of Investments. 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"). Upon adoption, equity investments with readily determinable fair values may no longer be designated as AFS, and thus, the change in fair value for these investments is now accounted for within the consolidated statements of income. As of December 31, 2019 and 2018, the fair value of equity investments with a readily determinable fair value recorded on the consolidated statements of condition was $1.7 million and $746,000, respectively. For the year ended December 31, 2019 and 2018, an unrealized gain (loss) of $928,000 and ($50,000), respectively, was recorded within other income on the consolidated statements of income for the year ended December 31, 2018.

Equity investments with a readily determinable fair value are no longer assessed for OTTI as the change in fair value is now recorded within net income.

As of December 31, 2019 and 2018, the Company did not have any equity securities without a readily determinable fair value within the scope of ASU 2016-01.

We assess our investments in debt securities designated as AFS and HTM for OTTI quarterly, in conjunction with each reporting period. In determining whether OTTI has occurred, we review information about the underlying investment that is publicly available, analysts’ reports, applicable industry data and other pertinent information, and assess our intent and ability to hold the security for the foreseeable future until recovered. To the extent that the fair value of the debt security is below its carrying amount, we will assess if the impairment is due to credit-related or other factors. If it is due to credit-related factors, the investment is written down to its current fair value at the time the impairment is deemed to have occurred. If it is due to other factors, then no asset impairment is recorded. For the year ended December 31, 2019, 2018 and 2017, we did not record OTTI on any debt investments. Future adverse changes in market conditions, continued poor operating results of underlying investments or other factors could result in further losses that may not be reflected in an investment’s current carrying value, possibly requiring an additional impairment charge in the future.

As of December 31, 2019 and 2018, we did not have any equity or debt investments for which fair value was determined using level 3 valuation techniques and assumptions. The fair value of all equity and debt investments were measured using level 2 techniques. Refer to Note 21 of the consolidated financial statements for further details of fair value.

Effective January 1, 2020, the Company adopted ASU No. 2016-13, Financial Instruments - Credit Losses(Topic 326): Measurement of Credit Losses on Financial Instruments, including its updates and amendments, which changed the impairment model for AFS debt securities. Under this standard, AFS debt securities are still considered impaired and required to be written down if the fair value of the security is less than its carrying value and the Company does not have the intent and/or ability to hold the security for the foreseeable future until recovered. The new AFS debt security model differs from the current OTTI model in that it no longer allows consideration of the length of time which the fair value has been less than its carrying value when determining whether a credit loss exists. Thus, an OTTI due to a credit-related factor may be recorded earlier under the new impairment model for AFS debt securities than the current OTTI model. Furthermore, under the new model, if OTTI is recorded it is accounted for as a valuation allowance on AFS investments, and it is recoverable to the extent of the valuation allowance.

33

Income Taxes. We account for income taxes by deferring income taxes based on the estimated future tax effects of differences between the book and tax bases of assets and liabilities considering the provisions of enacted tax laws. These differences result in deferred tax assets and liabilities, which are included in the consolidated statements of condition. We must also assess the likelihood that any deferred tax assets will be recovered from future taxable income and establish a valuation allowance for those assets determined not likely to be recoverable. Judgment is required in determining the amount and timing of recognition of the resulting deferred tax assets and liabilities, including projections of future taxable income. Although we have determined a valuation allowance is not required for our deferred tax assets, there is no guarantee that these assets will be realized.

On December 22, 2017, the Tax Act was enacted reducing the federal corporate income tax rate from 35.0% to 21.0%, effective January 1, 2018. In accordance with ASC 740, Income Taxes, we revalued our deferred tax assets and liabilities as of the enactment date, and, as a result, we recorded additional income tax expense for the year ended December 31, 2017 of $14.3 million. Refer to "—Results of Operations—Income Tax Expense" for further discussion.

As of December 31, 2019, our federal and state income tax returns for the year ended December 31, 2018, 2017 and 2016 were open to audit by federal and various state authorities. If, as a result of an audit, we were to be assessed interest and penalties, the amounts would be recorded through other non-interest expense on the consolidated statements of income.

Defined Benefit and Postretirement Plans. We use a December 31^stmeasurement date to determine the expenses for the Company's defined benefit and postretirement plans and related financial disclosure information. Postretirement plan expense is sensitive to changes in the number of eligible employees, changes in the discount rate, mortality rate, and other expected

rates, such as medical cost trends rates and salary scale assumptions.

EXECUTIVE OVERVIEW

The Company reported record net income and diluted EPS for 2019 of $57.2 million and $3.69, respectively. Net income for 2019 increased $4.1 million, or 8%, over 2018, while diluted EPS increased $0.30, or 9%, over the same period. Earnings growth in 2019 was attributable to an all-around successful year which is summarized by revenue (sum of net interest income and non-interest income) growth of 7% that outpaced expense growth of 4%, and superior asset quality that is highlighted by a non-performing assets to total assets ratio of 0.25% at December 31, 2019. Strong earnings growth in 2019 led to favorable financial performance metrics for the year, including a return on average assets of 1.30%, return on average equity of 12.44%, and a return on average tangible equity (non-GAAP) of 15.99%.

The Company's total revenue for 2019 totaled $169.7 million and was 75% net interest income and 25% non-interest income. We continue to manage our mix of revenue sources as we believe that a diversified revenue stream is important to our long-term success and ability to maintain financial margins. Net interest income for 2019 grew 6% over last year as we were able to hold our net interest margin relatively stable, decreasing 1 basis point to 3.15% for 2019, and growing average interest-earning assets 6% and average deposits 14%. Over the same period, non-interest income increased 10% as we continue to grow mortgage banking income, core banking service fees and wealth management services.

Non-interest expense for 2019 totaled $95.3 million, an increase of $3.4 million over 2018. We remain focused on managing costs to prudently grow the Company efficiently. For 2019, our ratio of non-interest expense to total revenues was 56.15%, and, on a non-GAAP basis adjusted for certain items, was 55.77%, compared to 57.98% and 57.71%, respectively, for 2018.

We are committed to driving shareholder value and we actively manage our usage of Company capital to drive financial returns. Throughout 2019, we took certain actions to redeploy capital and drive shareholder returns, including a 10% increase in the Company's fourth quarter cash dividend, and repurchasing 488,052 shares of Company common stock.

The following graphs depict the Company's financial performance over the last three years:

RESULTS OF OPERATIONS

Net Interest Income and Net Interest Margin

Net interest income is the interest earned on loans, securities, and other interest-earning assets, plus net loan fees, origination costs and fair value marks on loans and/or time deposits created in purchase accounting, less the interest paid on interest-bearing deposits and borrowings. Net interest income, which is our largest source of revenue, accounted for 75% and 76% of total revenues (sum of net interest income and non-interest income) for 2019 and 2018, respectively. Net interest income is affected by factors including, but not limited to, changes in interest rates, loan and deposit pricing strategies and competitive conditions, loan prepayment speeds, the volume and mix of interest-earning assets and interest-bearing liabilities, and the level of non-performing assets. Net interest margin is calculated as net interest income, on a fully-taxable equivalent basis, as a percentage of average interest-earning assets. Our net interest margin on a fully-taxable equivalent basis for 2019 and 2018 was 3.15% and 3.16%, respectively.

Net interest income on a fully-taxable equivalent basis for 2019 was $128.7 million, an increase of $7.2 million, or 6%, over 2018. The increase was driven by average loan growth of $223.3 million, or 8%, but was partially offset by a decline in the net interest margin on a fully-taxable equivalent basis of 1 basis point to 3.15% for 2019. The decrease in net interest margin on a fully-taxable equivalent basis was primarily driven by the decrease in fair value mark accretion and recoveries from charged-off acquired loans of $692,000. Adjusted for fair value mark accretion and recoveries from charged-off acquired loans, net interest margin on a fully-taxable equivalent basis increased 1 basis point to 3.11% for 2019, compared 2018.

The interest rate environment in 2019 was the tale of two halves. Interest rate momentum in 2018, which included four federal fund rate increases for a total of 100 basis points, carried forward into the first half of 2019. For the first half of 2019, the average federal funds effective rate was 2.40%, and the average 10-year U.S. treasury rate was 2.48%, including a rate range during this period of 2.00% – 2.79%. In the second half of 2019, the federal funds rate was cut three times for a total of 75 basis points. By the end of 2019, the federal funds effective rate was 1.55%, and the average 10-year U.S. treasury rate for the second half of 2019 was 1.79%, including a range during this period of 1.47% – 2.13%.

Our interest-earning asset yield for 2019 was 4.15%, an increase of 18 basis points over 2018. Loan yields increased 16 basis points to 4.65% for 2019, and cash and investment yields increased 18 basis points to 2.60% for 2019. The increase in loan yields was driven by strong net loan growth for the 12-months leading up to June 30, 2019 of $232.8 million, or 8%, in the period in which interest rates were rising. However, as interest rates decreased in the second half of 2019, new loans were priced at lower yields and existing loans re-priced to lower yields, causing our loan yield to steadily decrease throughout the second half of 2019. The increase in our yield on cash and investments year over year was attributable to various investment portfolio restructuring activities we completed in 2018 and 2019, and continued re-investment of cash flows into higher yielding securities, which included increasing the duration of our debt investments portfolio. Refer to "—Financial Condition—Investments" for additional details.

Our cost of funds for 2019 was 1.05%, an increase of 20 basis points over 2018. Deposit and borrowing costs each increased 29 basis points to 0.81% and 2.25%, respectively, for 2019. Average deposits grew $390.9 million, or 14%, in 2019, compared to 2018, and increased the Company's ratio of average deposits to total funding liabilities for 2019 to 83%, compared to 78% for 2018. The change in our funding mix in 2019 is due to strong average deposits growth which enabled us to manage the increase in cost of funds year over year.

The following table presents, for the periods noted, average balances, interest income, interest expense, and the corresponding average yields earned and rates paid, as well as net interest income, net interest rate spread and net interest margin:

Provision for Credit Losses

The provision for credit losses is primarily made up of our provision for loan losses, but also includes the provision for unfunded commitments.

The provision for loan losses is a recorded expense determined by management that adjusts the ALL to a level that, in management’s best estimate, is necessary to absorb probable losses within the existing loan portfolio. The provision for loan losses reflects loan quality, including, among other factors, the levels of and trends related to non-accrual loans, past due loans, potential problem loans, criticized loans, net charge-offs or recoveries and growth in the loan portfolio. Accordingly, the amount of the provision for loan losses reflects the necessary increases in the ALL related to newly identified criticized loans, as well as the actions taken related to other loans including, among other things, any necessary increases or decreases in required allowances for specific loans or loan pools.

The provision for loan losses for 2019 was $2.9 million, or 0.09% of average loans, compared to $845,000, or 0.03% of average loans for 2018. For 2019, net charge-offs to average loans were 0.08%, compared to 0.01% for 2018. Our ratio of net charge-offs to average loans for 2018 was lower primarily due to the favorable resolution of a significant commercial credit relationship that resulted in a large recovery.

The provision for unfunded commitments represents management's estimate of the amount required to reflect the probable inherent losses on outstanding letters and unused lines of credit. The reserve for unfunded commitments is presented within accrued interest and other liabilities on the consolidated statement of condition. The provision for unfunded commitments for 2019 and 2018 was immaterial. Refer to Note 3 of the consolidated financial statements for further discussion.

Non-Interest Income

The following table sets forth information regarding non-interest income for the periods indicated:

(1) Revenue is the sum of net interest income and non-interest income.

Debit card income represents theinterchange fees earned from debit card transactions of our business and consumer checking account customers. The increase for 2019 over 2018 was driven by an increase in customer transactions of 8%, which also resulted in an annual incentive bonus from our network provider of $579,000 for 2019, compared $530,000 for 2018.

Service charges on deposit accounts represents the fees earned from providing various services to deposit customers, including non-sufficient funds fees, normal fees for servicing deposit accounts, and cash management fees for business customers. The increase for 2019 over 2018 was driven by an increase in cash management fees as we continue to grow business checking account customers.

Mortgage banking income, net is generated through the sales of residential mortgage loans in the secondary market and also includes any income recognized upon the sale of a residential mortgage in which we maintain the servicing rights, net of

40

related amortization of the capitalized asset. Our current practice has been to sell the servicing rights for residential mortgages originated, except for certain third party relationships that require the Company to service the loan. The increase in mortgage banking income for 2019 over 2018 was primarily driven by an increase in residential mortgage sales of 32%, in part driven by higher refinance activity due to the interest rate environment, and an increase in the fair value of loans held for sale and interest rate lock commitments between periods.

Income from fiduciary services represents the fees earned for investment advisory and trust services provided by Camden National Wealth Management. The fees earned are primarily a percentage of our clients' assets under management. In 2019, assets under management increased 20% to $1.0 billion as of December 31, 2019. In 2019, Camden National Wealth Management reached a new milestone with $96.1 million of new business.

Brokerage and insurance commissions represent the fees earned for brokerage services, investment advisory and insurance services provided by the Bank, doing business as Camden Financial Consultants. The increase for 2019 over 2018 was driven by fees for advisory services and annuity product sales.

Bank-owned life insurance represents the change in cash surrender value of the Company's various BOLI policies in place for certain current and former officers of the Company and Bank. The change in cash surrender value reflects the performance of the underlying investments of the policies. The decrease in income for 2019, compared to 2018 was due to the change in cash surrender value of our BOLI policies.

Customer loan swap fees represents fees earned from the counterparty upon execution of a back-to-back commercial loan swap with our customers. Refer to "—Contractual Obligations and Off-Balance Sheet Commitments" and Note 12 of the consolidated financial statements for further discussion of our back-to-back commercial loan swap program.

Net (loss) gain on sale of securities represents the realized (loss) gain upon sale of various investments. In 2019, we executed various investment portfolio restructure strategies to improve our investment yield. In doing so, we sold investments designated as AFS with a book value of $207.1 million and realized losses of $105,000. In 2018, we sold all of our shares of Visa Inc. Class B common stock for a gain of $938,000 and sold certain debt investments and recognized a net loss of $663,000 as we restructured our investments portfolio to increase our investment yield in future periods. This resulted in a net gain on sale of securities of $275,000 for 2018.

Other Income. Other income includes third party merchant and credit card commissions, other miscellaneous fees, and, for 2019 and 2018, the unrealized gain (loss) on the change in fair value of equity securities. The increase in 2019 over 2018 was primarily driven by an increase in the unrealized gain (loss) on change in fair value of our investment in another bank's stock of $928,000 upon the announcement of its intent to merge with another bank in 2020. The fair value of our investment in bank stock is determined using Level 2 valuation techniques. Refer to Note 21 for further details on the Company's valuation methodology.

Efficiency ratio (non-GAAP)	55.77		%	57.71		%	57.05		%

(1) Revenue is the sum of net interest income and non-interest income.

Salaries and employee benefits include employee wages, commissions, incentives, equity compensation, employer-related taxes, insurance benefits, and other certain employee-related costs, net of direct employee-related costs incurred for loan originations. The increase in 2019 over 2018 was driven by (i) an increase in wages and related taxes of 5%; (ii) increased health insurance costs of 10%; and (iii) an increase in bonuses and incentives based on annual performance to budget, including an additional special bonus of $750 to certain non-executive, non-senior management employees accrued at December 31, 2019 and paid in February 2020.

Furniture, equipment and data processing includes depreciation expense of capitalized furniture, equipment and data-related costs, and ongoing system and other data processing costs, including outsourced solutions. The increase in 2019 over 2018 was driven by the technology and data-related investments made over the past several years to support the Company's strategic initiatives and enhance the customer experience.

Net occupancy costs include building and property costs associated with the operation of our branches, loan production offices and service centers, including, but not limited to, rent, depreciation, maintenance and related taxes, net of rental income earned from the lease of office space. The increase in 2019 over 2018 was driven by our continued investment in our branches and facilities, with a focus and priority on our strategic markets and locations.

Consulting and professional fees include third party consulting services and other professional fees, such as audit and tax services, legal services, and Company and Bank director fees.

Debit card expense is the costs incurred in the generation of debit card income, including third party switch network provider fees and related data transmission costs, and plastic card costs for the generation of debit cards for checking account customers. The increase in 2019 over 2018 was directly related to the increase in customer activity.

Regulatory assessments are the costs incurred and paid to various regulatory agencies, including the FDIC and OCC. The decrease in 2019 compared to 2018 was driven by receipt of a Small Bank Assessment Credit from the FDIC for our second and third quarter 2019 assessment periods. It is anticipated that the Company will receive further FDIC fee credits in the first half of 2020, should the FDIC continue to meet and exceed its required Deposit Insurance Fund reserve ratio.

OREO and collection costs, net include the costs associated with OREO, collection and foreclosure efforts on Bank loans. The decrease in 2019 compared to 2018 reflects our excellent asset quality through 2019 and reimbursements of collection-related costs in 2019 that were incurred in 2018.

Amortization of core deposit intangible assets represents the amortization expense on core deposit intangible assets.

42

Other expenses include employee-related costs, such as certain SERP and other postretirement benefits expenses; hiring, training, education, meeting and business travel costs; donations and marketing costs; postage, freight and courier costs; and other expenses.

Income Tax Expense

Income tax expense for 2019 and 2018 was $14.4 million and $12.7 million, respectively, which resulted in an effective income tax rate of 20.1% for 2019 and 19.3% for 2018. The change in our effective tax rate between periods was driven by a decrease in windfall tax benefits recognized upon vesting of equity awards and exercise of stock options, offset by an increase in state income taxes, net of federal benefit, as the Company continues to expand its presence outside of Maine into higher corporate income tax states for financial institutions, including Massachusetts and New Hampshire.

Our effective income tax rate for 2019 of 20.1% was lower than our marginal tax rate of 22.5%, which includes a 21.0% federal income tax rate and 1.5% state income tax rate, net of federal tax benefit, due to non-taxable interest income from municipal bonds and certain qualifying loans, non-taxable BOLI, tax credits received on qualifying investments, and windfall tax benefits upon vesting of equity awards and/or exercise of stock options.

At December 31, 2019 and 2018, we had $48.2 million and $52.1 million, respectively, of acquired federal net operating losses. Due to Internal Revenue Code Section 382(g) limitations, our use of the acquired federal net operating losses is limited to $3.9 million annually. These acquired federal net operating losses will expire between 2030 and 2034, and we expect to fully utilize them prior to expiration, as we have a history of generating taxable income well in excess of this usage limitation.

We continuously monitor and assess the need for a valuation allowance on our deferred tax assets. At December 31, 2019 and 2018, we determined that no valuation allowance was necessary.

Refer to Note 19 of the consolidated financial statements for further discussion of income taxes and related deferred tax assets and liabilities.

2018 Operating Results as Compared to 2017 Operating Results

The Company's net income for 2018 of $53.1 million, was an increase of $24.6 million, or 86%, over 2017. Over the same period, diluted EPS increased $1.57, or 86%, to $3.39 per share for 2018. For 2018, the Company's ratio of non-interest expense to total revenues was 57.98%, and on a non-GAAP basis adjusted for certain items, was 57.71% compared to 57.51% and 57.05%, respectively, for 2017. The 2018 operating results compared to 2017 were driven by the following:

Net Interest Income and Net Interest Margin. Net interest income on a fully-taxable equivalent basis for 2018 was $121.4 million, an increase of $4.0 million, or 3%, over 2017. The increase was driven by average loan growth of $155.9 million, or 6%, but was partially offset by a decline in the net interest margin on a fully-taxable equivalent basis of 3 basis points to 3.16% for 2018. The decrease in net margin on a fully-taxable equivalent basis was primarily driven by the decrease in fair value mark accretion and recoveries from charged-off acquired loans of $902,000. Adjusted for fair value mark accretion and recoveries from charged-off acquired loans, net interest margin on a fully-taxable equivalent basis was 3.10% for 2018 and 2017.

Provision for Credit Losses. The provision for credit losses for 2018 was $847,000, a decrease of $2.1 million compared to 2017. The provision for credit losses consists of the provision for loan losses and unfunded commitments.

• For 2018, the provision for loan losses was $845,000, or 0.03% of average loans, compared to $3.0 million, or 0.11% of average loans for 2017. The decrease in the provision for loan losses between periods of $2.2 million was driven by (i) a decrease in net charge-offs of $1.7 million, primarily due to the favorable resolution of a significant commercial credit relationship previously on non-accrual, resulting in a net charge-offs to average loans ratio for 2018 of 0.01% compared to 0.07% for 2017, and (ii) improved asset quality, highlighted by a decrease in our ratio of non-performing loans to total loans of 25 basis points to 0.48% at December 31, 2018, compared to December 31, 2017.

• For 2018, the provision for unfunded commitments was $2,000, compared to $9,000 for 2017.

Non-Interest Income. Non-interest income for 2018 was $38.2 million, compared to $38.6 million for 2017. The decrease of $423,000, or 1%, was driven by (i) a decrease in mortgage banking income of $1.4 million due to lower sales production and a decline in the fair value of loans held for sale and interest rate lock commitments between periods; (ii) a decrease in customer loan swaps of $618,000; and (iii) a decrease in net gain on sale of securities of $580,000. These decreases were partially offset by (i) an increase in debit card income of 12% driven by an increase in transactions and a $506,000 increase in our annual bonus from our network provider; and (ii) an increase in brokerage service income and fiduciary income of 10%.

43

Non-Interest Expense.Non-interest expense for 2018 was $91.9 million, compared to $88.5 million for 2017. The increase of $3.4 million, or 4%, was driven by (i) an increase in salaries and employee benefits expense of 5% driven by normal merit increases, additional positions added throughout 2018, and an 11% increase in health insurance costs; (ii) an increase in other expenses of 7% driven by an increase in external recruiting fees due to the hiring of various key positions in 2018, and an increase in training costs as we launched a new employee training program; (iii) an increase in consulting and professional fees of $634,000 driven by the support of various strategic initiatives and ongoing legal services; (iv) an increase in furniture, equipment and data processing costs of 5% driven by ongoing technology and data-related investments in support of strategic initiatives; and (v) an increase in debit card expense of $425,000 due to the increase in customer transactional activity, which also drives the corresponding increase of debit card income. These increases were partially offset by decreases in intangible asset amortization of $1.1 million and regulatory assessment fees of $229,000.

Income Tax Expense. Income tax expense for 2018 was $12.7 million, with an effective tax rate of 19.3%, compared to $33.9 million for 2017, with an effective tax rate of 54.3%. The decrease in the effective tax rate between periods was driven by a $14.3 million income tax charge in the fourth quarter of 2017 upon enactment of the Tax Act, and a reduction in the federal corporate income tax rate from 35.0% to 21.0%, effective for 2018.

Impact of Inflation and Changing Prices

The consolidated financial statements and the notes to the consolidated financial statements presented within have been prepared in accordance with GAAP, which requires the measurement of the financial position and operating results in terms of historical dollars and, in some cases, current fair values without considering changes in the relative purchasing power of money over time due to inflation. Unlike many industrial companies, substantially all of our assets and virtually all of our liabilities are monetary in nature. As a result, interest rates have a more significant impact on our performance than the general level of inflation. Over short periods of time, interest rates and the yield curve may not necessarily move in the same direction or in the same magnitude as inflation.

44

FINANCIAL CONDITION

Cash and Cash Equivalents

Total cash and cash equivalents at December 31, 2019 were $75.6 million, compared to $67.0 million at December 31, 2018. The increase in cash and cash equivalent balances of $8.6 million between periods was driven by an increase in reserve requirements by the FRB, resulting primarily from transactional deposit account growth during 2019, which included non-interest and interest checking account growth of $185.7 million, or 12%. We continuously monitor our cash levels to ensure compliance with applicable regulatory requirements, including liquidity and FRB reserve requirements.

Investments

The Company utilizes the investment portfolio to manage liquidity, interest rate risk, and regulatory capital, as well as to take advantage of market conditions to generate a favorable return on investments without undue risk. The Company’s investment portfolio consists of debt securities we have designated as AFS, debt securities we have designated as HTM and common stock of the FHLBB, FRB and certain banks. Investments increased $6.4 million, or 1%, at December 31, 2019. The increase was attributable to periodic purchases throughout the year totaling $353.0 million, partially offset by paydowns, calls and sales of $371.3 million and a $27.8 million increase in the fair value of certain securities based on changes in market interest rates. The ratio of investments to total assets was 21% at December 31, 2019, compared to 22% at December 31, 2018.

The investment portfolio has limited credit risk due to its composition, which includes securities with credit ratings in the highest category by nationally recognized rating agencies and securities backed by the U.S. Government and government sponsored agencies. At December 31, 2019 and 2018, these investments represented approximately 85% and 86%, respectively, of the investment portfolio. The majority of the municipal bonds, which represented 13% and 10% of the investment portfolio at December 31, 2019 and 2018, respectively, had a credit rating of "AA" or higher.

Our investments in FHLBB and FRB common stock are carried at cost. These investments are presented within other investments on the consolidated statements of condition. We are required to maintain a level of investment in FHLBB stock based on our level of FHLBB advances, and maintain a level of investment in FRB common stock based on the Bank's capital levels. As of December 31, 2019 and 2018, our investment in FHLBB stock totaled $6.6 million and $8.6 million, respectively, and our investment in FRB stock was $5.4 million.

The Company monitors its investment securities for the presence of OTTI. For debt securities, which made up 98% of our investment portfolio at December 31, 2019, the primary consideration in determining whether impairment is OTTI is whether or not the Bank expects to collect all contractual cash flows. There was no OTTI recorded on investments in 2019, 2018 or 2017. Refer to "—Results of Operations—Critical Accounting Policies" and Note 2 of the consolidated financial statements for further discussion.

(1) Upon adoption of ASU No. 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities, effective as of January 1, 2018, re-designated $92.0 million of qualifying HTM investments to AFS.

(2) Upon adoption of ASU 2016-01, effective as of January 1, 2018, equity investments with a readily determinable fair value are no longer designated and accounted for as AFS, instead were presented within other investments at fair value.

(3) The decrease in FHLBB stock of $9.7 million since December 31, 2017 to $8.6 million at December 31, 2018 was driven by the decrease FHLBB overnight borrowings and advances of $272.2 million between periods to $35.0 million at December 31, 2018.

We continuously monitor and evaluate our investment securities portfolio to identify and assess risks within our portfolio, including, but not limited to, the impact of the current rate environment and the related prepayment risk, and review credit ratings. The overall mix of debt securities at December 31, 2019 compared to December 31, 2018 remains relatively unchanged and well positioned to provide a stable source of cash flow. The duration of our debt investment securities portfolio at December 31, 2019 was 4.7 years, compared to 4.1 years at December 31, 2018. We are currently investing in longer duration debt securities, or those with call protection, to limit prepayment risk and to protect against a lower interest rate environment.

The following table presents the book value (i.e. amortized cost) and fully-taxable equivalent weighted-average yields of debt investments by contractual maturity for the periods indicated. Actual maturities will differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties.

Residential Real Estate. Residential real estate loans consist of loans secured by one-to four-family properties, including for investment purposes. We generally retain in our portfolio adjustable rate mortgages, fixed rate mortgages with original terms of 30 years or less, and jumbo/non-conforming residential mortgages.

For the year ended December 31, 2019, our total residential mortgage production totaled $570.3 million, an increase of 15% over 2018. In 2019, we sold 50% of our residential mortgage production to secondary market participants, compared to 44% for 2018. Refinancing activity was 37% of residential real estate originations, compared to 24% in 2018.

As part of our overall asset/liability management strategy, we will sell residential mortgages we originate to secondary market participants to manage our interest rate risk position and generate non-interest income. Factors we consider in determining which loans to sell, include, but are not limited to, current and future outlook of the interest rate environment; loan terms, including loan size, interest rate, fixed or variable and maturity date; and estimated prepayment speed.

Commercial Real Estate. Commercial real estate loans consist of loans secured by income and non-income producing commercial real estate. We focus on lending to financially sound business customers primarily within our geographic marketplace, as well as offering loans for the acquisition, development and construction of commercial real estate.

In 2019, commercial real estate loans decreased $26.1 million, or 2%, primarily due to elevated prepayments. Commercial real estate loan activity was steady and competitive within our markets throughout 2019. In 2019, commercial real estate loan

production reached a new milestone with $361.0 million of originations, of which $137.5 million were construction loans yet to fund as of December 31, 2019.

The most significant industry concentration within our commercial real estate loan portfolio at December 31, 2019 and 2018 was the non-residential building operators industry (operators of commercial and industrial buildings, retail establishments, theaters, banks and insurance buildings). At December 31, 2019, the non-residential building operators' industry concentration was 31% of our total commercial real estate portfolio and 12% of total loans. At December 31, 2019, there were no other industry concentrations within our loan portfolio that exceeded 10% of total loans.

Commercial. Commercial loans consist of loans secured by various corporate assets, as well as loans to provide working capital in the form of lines of credit, including syndication loans, which may be secured or unsecured. Commercial loans also consist of municipal loans which are primarily short-term tax anticipation notes made to municipalities for fixed asset or construction-related purposes.

In 2019, commercial loans grew $39.3 million, or 10%. Commercial loan originations totaled $212.3 million in 2019, driven primarily by small business loans. Syndication loans were 10% of total loan originations in 2019. At December 31, 2019 and 2018, syndication loans made up 17% of total commercial loans.

Consumer and Home Equity. Consumer and home equity loans are originated for a wide variety of purposes designed to meet the needs of our customers. Consumer loans include overdraft protection, automobile, boat, recreational vehicle, and mobile home loans, home equity loans and lines, and secured and unsecured personal loans.

In 2019, consumer loans grew $5.1 million, or 25%, to $25.8 million at December 31, 2019. At December 31, 2019 and 2018, 36% and 41%, respectively, of the consumer loan portfolio was unsecured.

In 2019, home equity loans decreased $15.0 million, or 5%, to $312.8 million at December 31, 2019. At December 31, 2019 and 2018, 54% of home equity loans were secured by first lien positions, and 46% were secured by junior lien positions.

HPFC. HPFC is a wholly-owned subsidiary of the Bank that provided commercial lending to dentists, optometrists and veterinarians, many of which are start-up companies. HPFC's loan portfolio consists of term loan obligations extended for the purpose of financing working capital and/or purchase of equipment. Collateral may consist of pledges of business assets including, but not limited to, accounts receivable, inventory, and/or equipment. These loans are primarily paid by the operating cash flow of the borrower and the terms range from seven to ten years. We discontinued HPFC's operations in February 2016, and the HPFC loan portfolio will continue to decrease until all loans have matured.

In 2019, the HPFC loan portfolio decreased $12.1 million, or 36%.

48

Related Party Transactions

The Bank is permitted, in its normal course of business, to make loans to certain officers and directors of the Company and Bank under terms that are consistent with the Bank’s lending policies and regulatory requirements. In addition to extending loans to certain officers and directors of the Company and Bank on terms consistent with the Bank’s lending policies, federal banking regulations also require training, audit and examination of the adherence to this policy by representatives of the federal and national regulators (also known as “Regulation O” requirements). Note 3 and Note 8 of the consolidated financial statements provide related party lending and deposit information, respectively. We have not entered into significant non-lending related party transactions.

Asset Quality

The Bank's Board of Directors monitors credit risk through the Directors’ Loan Review Committee, which reviews large credit exposures, monitors external loan reviews, 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, concentration levels, and the ALL methodology. Credit Risk Administration and the Credit Risk Policy Committee oversee management’s systems and procedures to monitor the credit quality of the loan portfolio, conduct a loan review program, maintain the integrity of the loan rating system, determine the adequacy of the ALL, and support the oversight efforts of the Directors' Loan Review Committee and the Board of Directors. Our practice is to manage the portfolio proactively such that management can identify problem credits early, assess and implement effective work-out strategies, and take charge-offs as promptly as practical. In addition, management continuously reassesses its underwriting standards in response to credit risk posed by changes in economic conditions.

Non-Performing Assets. Non-performing assets include non-accrual loans, accruing loans 90 days or more past due, accruing renegotiated loans, and OREO. The level of our non-performing assets over the past five years is shown in the table below.

Generally, a loan is classified as non-accrual when interest and/or principal payments are 90 days past due or when management believes collecting all principal and interest owed is in doubt. All previously accrued but unpaid interest on non-accrual loans is reversed from interest income in the current period. 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, all future principal and interest payments are reasonably assured, and a consistent repayment record, generally six consecutive payments, has been demonstrated. At this time, we may reclassify the

49

loan to performing. For loans that qualify as TDRs, we will classify the interest collected as interest income once the aforementioned criteria for non-accrual loans is met and demonstrated. However, 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 (i) the loan is subsequently restructured and re-written in a new agreement at an interest rate greater than or equal to an acceptable market rate for a comparable new loan at the time of the restructuring, and (ii) there has been no principal forgiveness.

The following table highlights the interest income that would have been recognized if loans on non-accrual status had been current in accordance with their original terms ("foregone interest income") and the interest income recognized on non-performing loans and performing TDRs for the periods indicated.

	For The Year Ended December 31,
(In thousands)	2019		2018		2017
Foregone interest income	$	420	$	600	$	843
Interest income recognized on non-performing loans and performing TDRs	162		193		215

Potential Problem Loans. Potential problem loans consist of classified accruing commercial and commercial real estate loans that were between 30 and 89 days past due. Such loans are characterized by weaknesses in the financial condition of our borrowers or collateral deficiencies. Based on historical experience, the credit quality of some of these loans may improve due to changes in collateral values or the financial condition of the borrowers, while the credit quality of other loans may deteriorate, resulting in some amount of loss. These loans are not included in the above analysis of non-accrual loans. At December 31, 2019 potential problem loans amounted to $1.4 million, or 0.05% of total loans.

Past Due Loans. Past due loans consist of accruing loans that were between 30 and 89 days past due. The following table presents the recorded investment of past due loans at the dates indicated:

	December 31,
(Dollars in thousands)	2019			2018
Loans 30 – 89 days past due:
Residential real estate	$	2,227		$	4,833

ALL. We use a methodology to systematically measure the amount of estimated loan loss exposure inherent in the loan portfolio for purposes of establishing a sufficient ALL. The ALL is management’s best estimate of the probable loan losses as of the balance sheet date. The allowance is increased by provisions charged to earnings and by recoveries of amounts previously charged-off, and is reduced by charge-offs on loans.

As part of normal course, we continuously monitor, and, at least annually, update our factors used to determine the general allowance for each loan portfolio segment. To derive our general allowance loss factors we utilize: (i) our historical loss data for each respective loan portfolio segment; (ii) identify other inherent risks within each portfolio segment, including, but not limited to, concentration risks, loans approved that are an exception to our internal loan policy, and construction loans; and (iii) consider certain qualitative factors that may influence a borrower's ability to repay their loan.

The Company completed its annual ALL policy review in the fourth quarter of 2019, and no significant changes to its ALL

methodology were made.

50

Reserve for Unfunded Commitments. The reserve for unfunded commitments is based on management’s estimate of the amount required to reflect the probable inherent losses on outstanding letters and unused loan credit lines. Adequacy of the reserve is determined using a methodology similar to the one that analyzes the allowance for loan losses. Additionally, management must also estimate the likelihood that these commitments would be funded and become loans.

Goodwill and Core Deposit Intangible Assets

Upon completion of an acquisition the Company will generate goodwill and other intangible assets. Goodwill represents the price paid in excess of the fair value of acquired assets and liabilities. Through the acquisition of other financial institutions, core deposit intangible assets are recognized at the estimated fair value of the acquired non-maturity deposit customer relationships. Goodwill is reviewed for impairment as of November 30^th annually, or more frequently as needed, and core deposit intangible assets are reviewed when a triggering event suggests such is necessary.

At December 31, 2019 and 2018, goodwill totaled $94.7 million. Through our annual impairment analysis, we determined goodwill was not impaired. At December 31, 2019 and 2018, core deposit intangible assets totaled $3.5 million and $4.2 million, respectively, and related amortization was $480,000, $935,000, and $971,000 for 2019, 2018 and 2017, respectively. There were no indications of potential risk of impairment of core deposit intangible assets for any of the aforementioned years.

Investment in BOLI

BOLI is presented in the consolidated statements of condition at its cash surrender value. Increases in BOLI’s cash surrender value are reported as a component of non-interest income in the consolidated statements of income.

BOLI was $92.3 million and $89.9 million at December 31, 2019 and 2018, respectively. The increase year-over-year reflects the increase in the cash surrender value. BOLI provides a means to mitigate increasing employee benefit costs. We expect to benefit from the BOLI contracts as a result of the tax-free growth in cash surrender value and death benefits that are expected to be generated over time. The largest risk to the BOLI program is credit risk of the insurance carriers. To mitigate this risk, annual financial condition reviews are completed on all carriers. BOLI is invested in the “general account” of quality insurance companies or in separate account products. 94% of the insurance carriers had an A.M. Best rating of "B++" or better at December 31, 2019.

Deposits

The Company receives checking, savings and time deposits primarily from customers located within our geographic market area. Other forms of deposits include brokered deposits and deposits with the Certificate of Deposit Account Registry System ("CDARS"). Total deposits at December 31, 2019 were $3.5 billion, which included brokered deposits of $191.0 million. Total deposits at December 31, 2019 increased $73.3 million, or 2%, over December 31, 2018. At December 31, 2019 and 2018, deposits were 91% of the Company's total funding of $3.9 billion and $3.8 billion, respectively. The components of the Company's net deposit growth in 2019 included:

• Checking account growth of $185.7 million, or 12%, even though one large municipal depositor shifted $70.0 million of interest checking balances to CDs in 2019.

• CD growth of $77.8 million, or 18%, was primarily attributable to one large municipal depositor shifting $70.0 million of interest checking balances to CDs in 2019.

52

• Brokered deposits decreased $172.1 million, or 47%, driven by strong checking and CD deposit growth in 2019. At December 31, 2019, brokered deposits were 5% of total deposits, compared to 10% of total deposits at December 31, 2018.

• Savings and money market accounts decreased $18.2 million, or 2%.

At December 31, 2019, the Company had no customer relationships that exceeded 10% of total deposits.

Borrowings and Advances

We utilize a variety of funding sources to manage our borrowings, including, but not limited to, FHLBB and correspondent bank overnight borrowings, FHLBB advances, customer and wholesale repurchase agreements, and subordinated debentures. We proactively monitor our borrowings through Management and Board ALCO as part of prudent balance sheet, earnings, and liquidity management. As part of our liquidity management, we use internal designations of "short-term" and "long-term" borrowings, and manage our borrowings within each designation:

• Short-term borrowings include, but are not limited to, FHLBB and correspondent bank overnight borrowings, FHLBB advances with maturity within one year of origination, and customer repurchase agreements.

• Long-term borrowings include, but are not limited to, FHLBB advances with maturity greater than one year, wholesale repurchase agreements, and subordinated debentures.

At December 31, 2019, short-term borrowings were $268.8 million, representing a decrease of $2.1 million, or 1%, since December 31, 2018. At December 31, 2019, long-term borrowings, including subordinated debentures, totaled $69.1 million, a decrease of $1.6 million, or 2%, since December 31, 2019. In 2019, we did not enter into any new long-term borrowing contracts.

Long-Term Borrowings. As of December 31, 2019 and 2018, we had $10.0 million of FHLBB advances outstanding at an interest rate of 1.87% that were scheduled to mature in April 2020.

As of December 31, 2019 and 2018, we had $15.0 million of subordinated debt issued and outstanding that qualified as Tier 2 regulatory capital. The interest rate on the subordinated debt was 5.50% per annum, fixed for the ten-year term and payable semi-annually. The subordinated debt is schedule to mature on October 15, 2025. We have the ability to exercise our call option on the subordinated debt on October 15, 2020. Refer to Note 9 of the consolidated financial statements for additional details.

In connection with the formation of CCTA and UBCT, and the issuance and sale of trust preferred securities to the public, we received and have outstanding at December 31, 2019 and 2018, junior subordinated debentures totaling $44.3 million and $44.4 million, respectively. We have five tranches of interest rate swaps on a total notional amount of $43.0 million of our junior subordinated debentures. The interest rate swaps were entered into as cash flow hedges to mitigate interest rate risk on variable rate debt. The interest rate swaps have various maturity dates beginning June 2021 through July 2031 at various fixed interest rates. Refer to Note 12 of the consolidated financial statements for additional details.

FHLBB Collateral. FHLBB short-term and long-term borrowings 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 $1.4 billion and $1.1 billion at December 31, 2019 and 2018, respectively. The carrying value of securities pledged as collateral at the FHLBB was $150,000 and $172,000 at December 31, 2019 and 2018, respectively.

Shareholders’ Equity

Total shareholders’ equity at December 31, 2019 was $473.4 million, which was an increase of $37.6 million, or 9%, since December 31, 2018. The increase was driven by normal operating activity, including, but not limited to, net income of $57.2 million for the year ended December 31, 2019, partially offset by dividends declared to shareholders of $18.9 million.

54

The Company's Board of Directors declared aggregate cash dividends for 2019 of $1.23 per share, compared to $1.15 per share for 2018 and $0.94 per share for 2017. The increase in cash dividends to shareholders highlights the financial and capital strength of the Company. At December 31, 2019 and 2018, the Company and the Bank exceeded all regulatory capital guidelines, and, specifically, the Bank met the capital ratios necessary to be considered "well capitalized" under prompt correct action provisions for each period. There were no changes to the Company or the Bank's capital that occurred subsequent to December 31, 2019 that would change the Company or Bank's regulatory capital categorization.

In January 2020, the Company's Board of Directors approved a new share repurchase program for up to 750,000 shares of the Company's common stock, or approximately 5% of shares outstanding at December 31, 2019, as the Company's current share repurchase program expired in January 2020. Repurchases under the new program may be made at the Company's discretion from time to time in the open market, through block trades or otherwise, and in privately negotiated transactions, subject to market conditions and other factors, and in accordance with applicable legal and regulatory requirements. If any share repurchases are made, they will be over a period of not greater than 12 months.

Refer to "—Capital Resources" and Note 14 of the consolidated financial statements for further discussion of the Company's capital position.

LIQUIDITY

Our liquidity needs require the availability of cash to meet the withdrawal demands of depositors and credit commitments to borrowers. Liquidity is defined as our ability to maintain availability of funds to meet customer needs, as well as to support our asset base. The primary objective of liquidity management is to maintain a balance between sources and uses of funds to meet our cash flow needs in the most economical and expedient manner. Due to the potential for unexpected fluctuations in both deposits and loans, active management of liquidity is necessary. We maintain various sources of funding and levels of liquid assets in excess of regulatory guidelines in order to satisfy their varied liquidity demands. We monitor liquidity in accordance with internal guidelines and all applicable regulatory requirements. At December 31, 2019 and 2018, our level of liquidity exceeded target levels. We believe that we currently have appropriate liquidity available to respond to liquidity demands. Sources of funds that we utilize consist of deposits, borrowings from the FHLBB and other sources, cash flows from operations, prepayments and maturities of outstanding loans, investments and mortgage-backed securities and the sale of mortgage loans.

Deposits continue to represent our primary source of funds. For 2019, average deposits (excluding brokered deposits) of $3.2 billion increased $390.9 million, or 14%, compared to 2018. The increase in average deposit balances (excluding brokered deposits) reflects organic deposit growth during 2019. Included within average money market deposits for 2019 and 2018 were $70.9 million and $48.4 million, respectively, of deposits from Camden National Wealth Management, which represent client funds. These deposits fluctuate with changes in the portfolios of the clients of Camden National Wealth Management. At December 31, 2019 and 2018, Camden National Wealth Management money market deposits were $84.5 million and $63.0 million, respectively.

Borrowings are used to supplement deposits as a source of liquidity. In addition to borrowings and advances from the FHLBB, we utilize brokered deposits, purchase federal funds, and sell securities under agreements to repurchase. For the year ended December 31, 2019, average total borrowings, including brokered deposits, decreased $175.5 million to $646.5 million compared to the same period last year. We secure borrowings from the FHLBB, with qualified residential real estate loans, certain investment securities and certain other assets available to be pledged. Customer repurchase agreements are secured by mortgage-backed securities and government-sponsored enterprises. Through the Bank, we have available lines of credit with the FHLBB of $9.9 million, with a correspondent bank of $50.0 million, and with the FRB Discount Window of $114.7 million as of December 31, 2019. The Company also has a $10.0 million line of credit with a correspondent bank that matures on December 18, 2020.

We believe the investment portfolio and residential loan portfolio provide a significant amount of contingent liquidity that could be accessed in a reasonable time period through sales of those portfolios. We also believe that we have additional untapped access to the brokered deposit market, wholesale reverse repurchase transaction market and the FRB discount window. These sources are considered as liquidity alternatives in our contingent liquidity plan. We believe that the level of liquidity is sufficient to meet current and future funding requirements; however, changes in economic conditions, including consumer saving habits and the availability or access to the national brokered deposit and wholesale repurchase markets, could significantly impact our liquidity position.

The maturity dates of CDs, including brokered CDs, in denominations of $100,000 or more as of December 31, 2019 are set forth in the table below. We did not hold any other time deposits in denominations of $100,000 or more at December 31, 2019. These deposits are generally considered to be more interest rate sensitive than other deposits and, therefore, more likely to be withdrawn to obtain higher yields elsewhere if available.

CAPITAL RESOURCES

As part of our goal to operate a safe, sound and profitable financial organization, we are committed to maintaining a strong capital base. Shareholders’ equity totaled $473.4 million and $435.8 million at December 31, 2019 and December 31, 2018, respectively, which amounted to 11% and 10% of total assets as of the respective dates. Refer to "— Financial Condition — Shareholders' Equity" for discussion regarding changes in shareholders' equity since December 31, 2018.

Our principal cash requirement is the payment of dividends on our common stock, as and when declared by the Company's Board of Directors. We declared dividends to shareholders in the aggregate amount of $18.9 million, $18.0 million and $14.6 million for the year ended December 31, 2019, 2018 and 2017, respectively. The Company's Board of Directors approves cash dividends on a quarterly basis after careful analysis and consideration of various factors, including the following: (i) capital position relative to total assets, (ii) risk-based assets, (iii) total classified assets, (iv) economic conditions, (v) growth rates for total assets and total liabilities, (vi) earnings performance and projections and (vii) strategic initiatives and related capital requirements. All dividends declared and distributed by the Company will be in compliance with applicable regulatory requirements and state corporate law.

We are primarily dependent upon the payment of cash dividends by the Bank, our wholly-owned subsidiary, to service our commitments. We, as the sole shareholder of the Bank, are entitled to dividends, when and as declared by the Bank's Board of Directors from legally available funds. For the year ended December 31, 2019, 2018, and 2017, the Bank declared dividends payable to the Company in the amount of $36.9 million, $28.1 million, and $16.8 million, respectively. Under regulations prescribed by the OCC, the Bank may not declare dividends in excess of the Bank’s net income for the current year plus its retained net income for the prior two years without prior approval from the OCC. If we are required to use dividends from the Bank to service unforeseen commitments in the future, we may be required to reduce the dividends paid to our shareholders going forward.

Please refer to Note 14 of the consolidated financial statements for discussion and details of the Company and Bank's capital regulatory requirements. At December 31, 2019 and 2018, the Company and Bank met all regulatory capital requirements and the Bank continues to be classified as "well capitalized" under prompt correction action provisions.

CONTRACTUAL OBLIGATIONS AND OFF-BALANCE SHEET COMMITMENTS

Off-Balance Sheet Financial Instruments

Credit Commitments and Standby Letters of Credit.In the normal course of business, we are a party to credit related financial instruments with off-balance sheet risk, which are not reflected in the consolidated statements of condition. These financial instruments include commitments to extend credit and standby letters of credit. Those instruments involve varying degrees of credit risk in excess of the amount recognized in the consolidated statements of condition. We follow the same credit policies in making commitments to extend credit and conditional obligations as we do for on-balance sheet instruments, including requiring similar collateral or other security to support financial instruments with credit risk. Our exposure to credit loss in the event of nonperformance by the customer is represented by the contractual amount of those instruments. Since many of the commitments are expected to expire without being drawn upon, the total amount does not necessarily represent future cash requirements. In the event of nonperformance by the borrower, we are entitled to underlying collateral, as applicable, which generally consists of pledges of business assets including, but not limited to, accounts receivable, inventory, plant and equipment, and/or real estate.

Derivatives.We use derivative financial instruments for risk management purposes (primarily interest rate risk) and not for trading or speculative purposes. We control the credit risk of these instruments through collateral, credit approvals and monitoring procedures. Additionally, as part of our normal mortgage origination process, we provide the borrower with the option to lock their interest rate based on current market prices. During the period from commitment date to the loan closing date, we are subject to the risk of interest rate change. In an effort to mitigate such risk, we may enter into forward delivery sales commitments, typically on a "best-effort" basis, with certain approved investors. We account for interest rate lock commitments on loans that will be held for sale as derivative instruments. Furthermore, we record a derivative for our "best-effort" forward delivery commitments upon origination of a loan identified as held for sale. Should we enter into a forward delivery commitment on a "mandatory delivery" arrangement with an investor, we account for the forward delivery commitment as a derivative upon execution of the mandatory delivery contract.

Hedge Instruments.From time to time, we may enter into derivative instruments as partial hedges against large fluctuations in interest rates. We may also enter into fixed rate interest rate swaps and floor instruments to partially hedge against potentially lower yields on the variable prime rate loan category in a declining rate environment. If interest rates were to decline, resulting in reduced income on the adjustable rate loans, there would be an increased income flow from the interest rate swap and floor instrument. We may also enter into variable rate interest rate swaps and cap instruments to partially hedge against increases in short-term borrowing rates. If interest rates were to rise, resulting in an increased interest cost, there would be an increased income flow from the interest rate swaps and cap instruments. These financial instruments are factored into our overall interest rate risk position. We regularly review the credit quality of the counterparty from which the instruments have been purchased.

Refer to Note 12 of the consolidated financial statements for further discussion of our derivatives and hedge instruments.

At December 31, 2019, we had the following levels of off-balance sheet financial instruments:

Contractual Obligations and Commitments

We are a party to several contractual obligations through lease agreements on a number of branches. Effective January 1, 2019, we adopted ASU 2016-02, Leases. In conjunction with the adoption of the new lease accounting standard, renewal options within the various lease contracts, as applicable, were considered to determine the lease term and estimate the contractual obligation and commitment for the Company's operating and finance leases. Furthermore, certain lease contracts of the Company contain language that subject its rent payment to variability, such as those tied to an index or change in an index. As a result, the future contractual obligation and commitment may materially differ from that estimated and disclosed within the table below. Upon adoption of the new lease accounting standard, the Company's estimated lease liability for its various operating and finance leases was reported within other liabilities on our consolidated statements of condition. Please refer to Notes 1 and 6 of the consolidated financial statements for discussion and details of our leases.

We enter into agreements routinely as part of our normal business to manage deposits and borrowings.

At December 31, 2019, we had an obligation and commitment to make future payments under each of these contracts as follows:

(In thousands)	Total Amount Committed		Payments Due Per Period
Contractual obligations and commitments			< 1 Year		1 – 3 Years		3 – 5 Years		> 5 Years
Operating leases	$	16,970	$	1,452	$	2,738	$	2,439	$	10,341

Total	$	358,824	$	281,608	$	3,086	$	2,787	$	71,343

Borrowings from the FHLBB consist of short- and long-term fixed and variable rate borrowings that are collateralized by all stock in the FHLBB and a blanket lien on qualified collateral consisting primarily of loans with first mortgages secured by one-to four-family properties, certain pledged investment securities and other qualified assets.

We have an obligation and commitment to repay all short- and long-term borrowings. These commitments and borrowings and the related payments are made during the normal course of business.

RISK MANAGEMENT

The Company’s Board of Directors and management have identified significant risk categories which affect the Company. The risk categories include: credit; liquidity; market; interest rate; capital; operational and technology, including cybersecurity; vendor and third party; people and compensation; compliance and legal; and strategic alignment and reputation. The Board of Directors has approved an Enterprise Risk Management ("ERM") Policy that addresses each category of risk. The direct oversight and responsibility for the Company's risk management program has been delegated to the Company's Executive Vice President of Risk Management, who is a member of the Executive Committee and reports directly to the Chief Executive Officer.

The Company is, and may become, subject to other risks, refer to Item 1A. Risk Factors for further description.

Credit risk is the current and prospective risk to earnings or capital arising from an obligor's failure to meet the terms of any contract with the Company or otherwise to perform as agreed. It is found in all activities in which success depends on counterparty, issuer or borrower performance. It arises any time funds are extended, committed, invested or otherwise exposed through actual or implied contractual agreements, whether reflected on or off the Company's balance sheet. The Company makes various assumptions and judgments about the collectability of its loan portfolio, including the creditworthiness of its borrowers and counterparties and the value of the real estate and other assets serving as collateral for the repayment of loans. For further discussion regarding credit risk and the credit quality of the Company’s loan portfolio, refer to "—Financial Condition—Asset Quality" and Note 3 of the consolidated financial statements.

Liquidity risk is the current and prospective risk to earnings or capital arising from the Company’s inability to meet its obligations when they come due, without incurring unacceptable losses. Liquidity risk includes the inability to manage unplanned decreases or changes in funding sources. Liquidity risk also arises from the failure to recognize or address changes in market conditions that affect the ability to liquidate assets quickly and with minimal loss in value. For further discussion regarding the Company's management of liquidity risk, refer to "—Liquidity" section.

Market risk is the risk of loss in a financial instrument arising from adverse changes in market rates and prices, such as interest rates, foreign currency exchange rates, commodity prices and equity prices. Our primary market risk exposure is interest rate risk. The ongoing monitoring and management of this risk is an important component of our asset and liability management process, which is governed by policies established by the Bank’s Board of Directors that are reviewed and approved annually. The Board ALCO delegates responsibility for carrying out the asset/liability management policies to Management ALCO. In this capacity, Management ALCO develops guidelines and strategies impacting our asset/liability management-related activities based upon estimated market risk sensitivity, policy limits and overall market interest rate levels and trends. Board ALCO meets on a quarterly basis to review strategies, policies, economic conditions and various activities as part of the management of these risks.

Certain of the Company's revenues are asset-based and determined as a percentage of the value of a client's assets under management. Such values are affected by changes in financial markets, such as interest rate risk, equity prices, and foreign exchange rates, and, accordingly, declines in the financial market may negatively impact its revenue. At December 31, 2019, client assets under management by Camden National Wealth Management were $1.0 billion. It is estimated that a 1% increase or decrease in client assets under management would have resulted in an annualized increase or decrease in reported 2019 income from fiduciary services of $59,000, which was estimated using average client assets under management and average fee rate earned for 2019.

Interest rate risk represents the sensitivity of earnings to changes in market interest rates. As interest rates change, the interest income and expense streams associated with our financial instruments also change, thereby impacting net interest income, the primary component of our earnings. Board ALCO and Management ALCO utilize the results of a detailed and dynamic simulation model to quantify the estimated exposure of net interest income to sustained interest rate changes. While Board ALCO and Management ALCO routinely monitor simulated net interest income sensitivity over a rolling two-year horizon, they also utilize additional tools to monitor potential longer-term interest rate risk.

The simulation model captures the impact of changing interest rates on the interest income received and interest expense paid on all interest-earning assets and interest-bearing liabilities reflected on our consolidated statements of condition, as well as for derivative financial instruments. This sensitivity analysis is compared to ALCO policy limits, which specify a maximum tolerance level for net interest income exposure over a one- and two-year horizon, assuming no balance sheet growth, given a 200 basis point upward and downward shift in interest rates. Although our policy specifies a downward shift of 200 basis points, this would have resulted in negative rates as of December 31, 2019 and 2018 as many deposit and funding rates were below 2.00%. In this case, a downward shift of 100 basis points was the only down scenario performed. A parallel and pro rata

61

shift in rates over a 12-month period is assumed. Using this approach, we are able to produce simulation results that illustrate the effect that both a gradual change of rates and a “rate shock” have on earnings expectations. In the down 100 and 200 basis points scenario, Federal Funds and Treasury yields are floored at 0.01% while Prime is floored at 3.00%. All other market rates are floored at 0.25%.

As of December 31, 2019, 2018 and 2017, our net interest income sensitivity analysis reflected the following changes to net interest income assuming no balance sheet growth and a parallel shift in interest rates. All rate changes were “ramped” over the first 12-month period and then maintained at those levels over the remainder of the ALCO simulation horizon.

	Estimated Changes in Net Interest Income
	As of December 31,
Rate Change from Year 1 – Base	2019		2018		2017
Year 1
+200 basis points	(0.59	)%	0.09	%	(0.22	)%
-100 basis points	(0.44	)%	(0.63	)%	(3.06	)%
-200 basis points(1)	Not measured		(1.63	)%	Not measured
Year 2
+200 basis points	3.96	%	6.79	%	6.86	%
-100 basis points	(5.55	)%	(0.90	)%	(8.08	)%
-200 basis points(1)	Not measured		(7.74	)%	Not measured

(1) The down 200 basis points scenario was not performed as of December 31, 2019 and 2017 as part of net interest income sensitivity analysis given market interest rates at that time.

The preceding sensitivity analysis does not represent a forecast and should not be relied upon as being indicative of expected operating results. These hypothetical estimates are based upon numerous assumptions including, among others, the nature and timing of interest rate levels, yield curve shape, prepayments on loans and securities, deposit decay rates, pricing decisions on loans and deposits and reinvestment/replacement of asset and liability cash flows. While assumptions are developed based upon current economic and local market conditions, we cannot make any assurances as to the predictive nature of these assumptions, including how customer preferences or competitor influences might change.

If rates remain at or near current levels, net interest income is projected to trend slightly upward as assets continue to settle into marginally higher rates while funding costs increase to a lesser extent. Beyond the first year, net interest income increases slightly. If rates decrease 200 basis points, net interest income is projected to decrease as loans reprice into lower yields and funding costs have limited capacity to reduce the cost of funds in the first year. In the second year, net interest income is projected to continue to decrease as loan and investment cash flow reprice into lower yields as prepayments increase while reduction in the cost of funds becomes limited. If rates increase 200 basis points, net interest income is projected to be flat in the first year due to the repricing of assets to match increases in short-term funding. In the second year, net interest income is projected to increase as loan and investment yields continue to reprice/reset into higher yields and the cost of funds lags.

Periodically, if deemed appropriate, we use interest rate swaps, floors and caps, which are common derivative financial instruments, to hedge our interest rate risk position. The Board of Directors has approved hedging policy statements governing the use of these instruments. As of December 31, 2019, we had interest rate swap agreements with a total notional of $43.0 million related to our junior subordinated debentures, $100.0 million of notional interest swap agreements on variable rate loans to mitigate exposure to falling interest rates, and $416.5 million of notional interest rate swap agreements related to commercial loan level derivative program with both our commercial customers and a corresponding swap dealer. The Board and Management ALCO monitor derivative activities relative to their expectations and our hedging policies.

LIBOR is a benchmark interest rate for certain floating rate loans, deposits and borrowings, and off-balance sheet exposures of the Company. In 2017, the U.K. Financial Conduct Authority, which regulates LIBOR, announced that it will not compel panel banks to contribute to LIBOR after 2021. As such, we have begun an internal project that is focused on an orderly transition from LIBOR to alternative reference rates. The markets for alternative rates are developing. We will continue to assess the use of alternative rates, and expect to transition to alternative rates as the markets and best practices develop.

Capital risk is the risk that an investor may lose all or part of the principal amount invested. The Company faces this risk as it manages its balance sheet and has investments or loans that may lose all or part of the principal amount the Company has

62

invested, which can have an impact on shareholders' equity. The Company also faces capital risk in that the entity may lose value on components of its shareholders' equity. The regulatory environment mandates the Company and Bank maintain certain levels of capital. These capital levels can change based upon regulatory changes, which can then impact what the Company is able to accomplish from a strategic perspective. For further discussion regarding capital risk and management of this risk, refer to "—Capital Resources" and Note 14 of the consolidated financial statements.

Operational risk is the current and prospective risk to earnings and capital arising from fraud, error and the inability to deliver products or services, maintain a competitive position and manage information. Risk is inherent in efforts to gain strategic advantage and in the failure to keep pace with changes in the financial services marketplace. Operational risk is evident in each product and service offered by the Company and encompasses product development and delivery, transaction processing, systems development, change management, complexity of products and services, human resource elements and the internal control environment. The risk that transactions may not be processed on time or correctly can have significant impact on the Bank’s reputation, which can result in compliance violations and fines, and/or other financial risks.

The Company manages operational risk through a series of internal programs, as well as through the assistance of third parties. These programs include various internal and external audit programs, internal committees to oversee compliance with programs and remedial actions, if necessary, and various documented policies, procedures and framework for addressing such risks.

Technology risk, including cybersecurity, is the risk offinancial loss, disruption or damage to the reputation of an organization resulting from the failure of its information technology systems, weak computing infrastructure, or a breach of information technology systems. Technology and cybersecurity risk could materialize in a variety of ways, such as unpatched or vulnerable computing systems, deliberate and unauthorized breaches of security to gain access to information systems, unintentional or accidental breaches of security, operational information technology risks due to factors such as poor system integrity, weak computing infrastructure and/or a weak Cybersecurity protection program.

Poorly managed technology and cybersecurity risk can leave an institution exposed to a variety of cybercrimes, with consequences ranging from data disruption to economic destitution. Reputation risk due to a technology and/or cybersecurity event can be significant to overcome depending on the severity of the event.

The Company manages technology and cybersecurity risks through its internal programs, as well as through the assistance of third parties. These programs include various internal and external audit programs, internal committees to oversee compliance with programs and remedial actions, if necessary, and various documented policies, procedures and framework for addressing such risks. Additionally, the Board actively oversees risks related to cybersecurity through various committees that are responsible for developing a comprehensive technology plan and monitoring and testing the Company's information security. The Company has also developed a Cybersecurity Incident Response Team ("CSIRT") that is responsible for monitoring, detecting, responding to and reporting cybersecurity incidents. The CSIRT uses a variety of monitoring and testing techniques to protect the integrity of the Company's systems and the security of confidential information.

Vendor and third party risk represents the risk related to outsourced activities and in certain situations includes reliance on vendors to deliver services on our behalf. The Company has many service partners and an increasing reliance on outsourced services, which places greater risk on the Company through these many partners. These relationships are controlled by contracts and service level agreements, but represent increasing risk to the Company.

The Company manages vendor and third party risk through its vendor management program, which includes robust due diligence and risk assessment prior to engaging a new vendor, annual review of certain vendors dependent on the services provided by the vendor and the risk the vendor may present to the Company through our reliance on its services.

People and compensation risk includes: the risk of employee dishonesty, incompetence or error; the risk of not having individuals with adequate training and experience to properly discharge their responsibilities; the risk of not having sufficient depth of personnel to provide back up for critical functions; the risk of lawsuit by employees alleging improper actions by or on behalf of the Company; succession planning; and compensation risk, which includes having compensation plans that effectively allow the Company to hire and keep the right talent, and properly designed compensation and incentive programs to promote ethical behavior and assure that excessive risk is not encouraged.

The Company manages people and compensation risk through annual risk assessments of various compensation and incentive plans, oversight by the Compensation Committee of the Board of Directors, the use of third party compensation consultants, and various insurance programs.

63

Compliance and legal risk is the current and prospective risk to earnings or capital arising from violations of, or nonconformance with, laws, rules, regulations, prescribed practices, internal policies and procedures, or ethical standards. This risk exposes the Company to fines, civil money penalties, payment of damages, and the voiding of contracts. Compliance risk can lead to diminished reputation, reduced franchise value, limited business opportunities, reduced expansion potential, and an inability to enforce contracts. Legal risk exists in generally all activity of the Company where there is any possibility that the Company will become subject to liability for improper actions.

The Company manages compliance and legal risk through various internal and external audit programs, use of third parties for consulting and legal support, ongoing compliance risk assessments, the ERM Committee and various insurance programs.

Strategic alignment risk is the current and prospective impact on earnings or capital arising from adverse business decisions, improper implementation of decisions, or lack of responsiveness to industry changes. This risk is a function of the compatibility of the Company's strategic goals, the business strategies developed to achieve those goals, the resources deployed against these goals, and the quality of implementation.

Reputation risk is the current and prospective impact on earnings and capital arising from negative public opinion. The reputation of financial services companies can be based on brand and trust, and the loss of brand or trust can negatively impact the Company's operations and financial results. Reputation risk exposure is present throughout the organization and our interactions with our various stakeholders, including, but not limited to, our customers, communities and investors.

The Company manages its strategic alignment and reputation risk through various internal policies and programs, including, but not limited to, the Company's core values, code of ethics policy, financial code of ethics policy, Audit Committee complaint policy, employee handbook, and other policies and programs, as well as through strategic planning and oversight by the Board of Directors.

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, Property A, Inc. and Property P, 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 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 ALL, 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.

Subsequent Events. The Company has evaluated events and transactions subsequent to December 31, 2019 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 is 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. The Company is required by the FRB to maintain cash reserves equal to a percentage of deposits. The Company maintains the reserve balances in cash on hand or at the FRB.

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.

For periods prior to January 1, 2018, the Company's investments in equity securities with a readily determinable fair value may have been classified as trading or AFS. The classification was determined at the time of purchase and reflected the Company's corporate goals and objectives. For such periods, equity securities with a readily determinable fair value classified as AFS were carried on the consolidated statements of condition at fair value. Subsequent changes to fair value were accounted for within AOCI, net of tax, on consolidated statements of condition. The Company did not have any equity securities with a readily determinable fair value classified as trading as of December 31, 2017.

Effective January 1, 2018, upon adoption of ASU No. 2016-01, Income Statement- Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Liabilities ("ASU 2016-01"), equity investments may no longer be designated and accounted for as AFS securities, with the change in fair value recognized within AOCI, net of tax. Instead, the change in fair value of equity investments with a readily determinable fair value are to be recognized within net income and carried at fair value on the balance sheet. Upon adoption of ASU 2016-01, a cumulative-effect adjustment of

71

$198,000 was recorded 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. This provision of ASU 2016-01 was applied prospectively. For the year ended December 31, 2019 and 2018, the Company recorded the change in fair value for its equity securities with a readily determinable fair value within other income on the consolidated statements of income. Refer to Note 2 for further details.

Management conducts a quarterly review and evaluation of its debt investments designated as AFS or HTM and, prior to the adoption of ASU 2016-01, effective January 1, 2018, conducted a quarterly review of its equity investments designated as AFS 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 debt investments classified as AFS or HTM that it does not intend to sell and is not more-likely-than-not will be 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 is recognized in non-interest income on the consolidated statements of income; and (ii) other factors is recognized in AOCI, net of tax. For the Company's debt securities it intends to sell and/or more-likely-than-not will be required to sell before recovery of amortized cost, an OTTI is 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.

Prior to the adoption of ASU 2016-01, for the Company's equity investments with a readily determinable fair value classified as AFS, for which the Company determined that the decline in the fair value was other-than-temporary, the Company would recognize the impairment within non-interest income on the consolidated statements of income when identified. Upon adoption of ASU 2016-01, effective January 1, 2018, the change in fair value of the Company's equity investments with a readily determinable fair value are recorded within net income and are no longer assessed for OTTI.

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.

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.

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 the Company's 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 are reported at amortized cost, or fair value in the case of acquired loans, 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. For acquired loans, interest income is also 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.

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

72

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.

ALL. The ALL is established through provisions for loan losses charged to income. Losses on loans, including impaired loans, are charged to the ALL when all or a portion of a loan is deemed to be uncollectible. Recoveries of loans previously charged off are credited to the ALL when realized.

In determining the appropriate level of ALL, the Company uses a methodology to systematically measure the amount of estimated loan loss exposure inherent in the loan portfolio. The methodology includes 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 is determined based on loans that have a principal balance of $500,000 or more that are classified as substandard or doubtful and are on non-accrual status. Such loans are classified as impaired and an allowance is established when the discounted expected future cash flows (or collateral value or observable market price) of the impaired loan is lower than the recorded investment of that loan. Loans that do not meet the above criteria are separated into risk pools by portfolio segment and risk ratings. The Company then evaluates 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 applies 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 currently an explicit part of the Company's methodology, could impact the risk rating assigned to that loan.

The Company at least annually, and more frequently as deemed prudent by management, reassesses and revises 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.

Since the methodology is based upon historical experience and trends, as well as management’s judgment, factors may arise that result in different estimations. Significant factors that could give rise to changes in these estimates may include, but are not limited to, changes in economic conditions in the Company’s market areas, concentration of risk, declines in local property values, and regulatory guidance.

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 are 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. 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

73

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.

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. 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 (commonly referred to as "Step Zero") 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 (i.e. "Step 1"). 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. If the reporting unit's fair value exceeds its carrying value, then goodwill is not impaired and no further assessment is required. However, if the reporting unit's fair value is less than its carrying value, the Company would then be required to determine the fair value of tangible and identifiable intangible assets and liabilities for the reporting unit, to derive an implied fair value of goodwill (i.e. "Step 2"). If the reporting unit's implied fair value of goodwill exceeds its carrying value, then goodwill is not impaired. However, if the reporting unit's implied fair value of goodwill is less than its carrying value, an impairment charge is recorded to carry goodwill at its calculated implied fair value.

The Company completed its annual goodwill impairment testing for its reporting unit as of November 30, 2019 using the qualitative analysis and it was determined that it was not more-likely-than-not that its carrying value exceeded its fair value. As such, goodwill was not impaired as of November 30, 2019.

Goodwill was tested for impairment as of November 30, 2018 and 2017 and was not impaired.

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, 2019, 2018 or 2017, 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.

74

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 ALL 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, 2019 and 2018, OREO properties were carried within other assets on the consolidated statements of condition at $94,000 and $130,000, 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.

Operating expenses, including legal and other direct expenses, and changes in the valuation allowance relating to foreclosed assets are included in other non-interest expense on the consolidated statements of income.

Mortgage Banking. Residential real estate mortgages are originated by the Company both for its portfolio and 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 non-interest income 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 loan servicing fee 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.

75

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, 2019 and 2018, 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

76

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. ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) ("ASC 606") was adopted by the Company on January 1, 2018. Refer to Note 16 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 Related Financial Instruments. 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. Refer to Note 11 for further details.

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

77

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 in 2019

ASU No. 2016-02, Leases (Topic 842) ("ASU 2016-02"): In February 2016, the FASB issued ASU 2016-02 to increase transparency and comparability among organizations by recognizing lease assets and liabilities (including operating leases) on the balance sheet and disclosing key information about leasing arrangements. Current lease accounting does not require the inclusion of operating leases in the balance sheet.

Effective January 1, 2019, the Company adopted ASU 2016-02, using the following practical expedients for transitional relief provided for within the subsequent issuance of ASU No. 2018-11, Leases (Topic 842): Targeted Improvements ("ASU 2018-11"):

• An entity need not reassess whether any expired or existing contract is or contains a lease.

• An entity need not reassess the lease classification for any expired or existing leases.

• An entity need not reassess initial direct costs for any existing leases.

• An entity may elect to apply hindsight to leases that existed during the period from the beginning of the earliest period presented in the financial statements until the effective date.

• A modified retrospective transition method, which allows companies to apply ASU 2016-02 at the date of adoption and recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption.

In conjunction with the adoption of Topic 842, the Company made the following accounting policy elections:

• For leases with a term of 12 months or less, a right-of-use asset or lease liability will not be recognized on the consolidated statements of condition.

• For non-real estate leased assets with individual undiscounted contractual cash flows of less than $500,000 over the reasonable certain term of the lease, a right-of -use asset or lease liability will not be recognized on the consolidated statements of condition as the lease is considered immaterial to the Company's financial statements.

The Company completed its assessment and implementation process for ASU 2016-02 and recorded operating and finance lease right-of-use assets of $12.1 million and lease liabilities of $12.3 million on the consolidated statements of condition within other assets and other liabilities, respectively, on January 1, 2019. Because the modified retrospective transition method was used, the Company did not revise prior period presentation on its consolidated statement of income. The adoption of the ASU did not have a material effect on the consolidated financial statements, which included a cumulative-effect adjustment of $254,000 to retained earnings on January 1, 2019. Refer to Note 6 for further details.

Recent Accounting Pronouncements to be Adopted in 2020

ASU No. 2016-13, Financial Instruments - Credit Losses(Topic 326): Measurement 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"), and ASU No. 2019-05, Financial Instruments - Credit Losses (Topic 326): Targeted Transition Relief ("ASU 2019-05").The FASB issued ASU 2016-13, commonly referred to as “CECL,” to require timelier recording of credit losses on loans and other financial instruments held by financial institutions and other organizations.

The Company will adopt ASU 2016-13, as amended, effective January 1, 2020, using a modified retrospective approach and will record a cumulative-effect adjustment to retained earnings. The measurement of expected credit losses under CECL is applicable to financial assets measured at amortized cost, including loan receivables and HTM debt securities. CECL also applies to certain off-balance sheet credit exposures, such as loan commitments, standby letters of credit, financial guarantees and other similar investments. In addition, ASU 2016-13 made changes to the accounting for AFS debt securities as a company will no longer immediately write-down a security for any impairment deemed to be a credit loss. Instead, a company will be required to present credit losses on AFS debt securities as an allowance on investments if it does not intend to sell the impaired security or it is not more-likely-than-not required to sell the impaired security before recovery of its amortized cost basis.

The Company assembled a cross-functional project team that met regularly to address the additional data requirements, to determine the approach for implementation and to identify new internal controls over enhanced accounting processes for estimating the allowance for credit losses (“ACL”). This included assessing the adequacy of existing loan and loss data, as well as assessing

78

models for default and loss estimates. The Company is currently working to finalize its internal CECL policy and internal control framework.

The Company has substantially completed the development of its process for estimation of the allowance for loan losses and off-balance sheet exposures (i.e. ACL). To estimate the allowance for loan losses, the Company will primarily utilize a discounted cash flow model that contains additional assumptions to calculate credit losses over the estimated life of financial assets and will include the impact of forecasted economic conditions. To estimate the off-balance sheet credit exposures, which are primarily unfunded loan commitments, the Company will apply certain assumptions, including, but not limited to, a funding assumption and expected loss rate.

The Company has performed a parallel calculation as of December 31, 2019, comparing the allowance for loan losses calculated under current accounting guidance, commonly referred to as the “Incurred Model,” to the ACL calculated under CECL. Upon adoption of CECL in the first quarter of 2020, the Company anticipates that it will result in an immaterial impact to its consolidated financial statements, including the ACL and retained earnings, as well as the Company and Bank’s regulatory capital ratios.

ASU No. 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment ("ASU 2017-04"):The FASB issued ASU 2017-04 to reduce the cost and complexity of the goodwill impairment test. To simplify the subsequent measurement of goodwill, "Step 2" of the goodwill impairment test was eliminated. Instead, in accordance with ASU 2017-04, a Company will recognize an impairment of goodwill to the extent the carrying value of a reporting unit exceeds its fair value (i.e. "Step 1"). The Company will adopt ASU 2017-04 on January 1, 2020.

Effective January 1, 2020, prospectively the Company will no longer give consideration to "Step 2" when performing its goodwill impairment test. The Company does not expect the ASU to have a material impact on its consolidated financial statements.

Net unrealized gains on AFS investments reported within in AOCI at December 31, 2019, were $3.3 million, net of a deferred tax liability of $890,000. Net unrealized losses on AFS investments reported within AOCI at December 31, 2018, were $17.8 million, net of a deferred tax benefit of $4.9 million, respectively.

Impaired AFS and HTM Investments

Quarterly, management reviews the Company’s AFS and HTM investments to determine the cause, magnitude and duration of declines in the fair value of each security. Thorough evaluations of the causes of the unrealized losses are performed to determine whether the impairment is temporary or other-than-temporary in nature. Considerations such as the ability of the securities to meet cash flow requirements, levels of credit enhancements, risk of curtailment, and recoverability of invested amount over a reasonable period of time, and the length of time the security is in a loss position, for example, are applied in determining OTTI. Once a decline in value is determined to be other-than-temporary, the cost basis of the security is permanently reduced and a corresponding charge to earnings is recognized.

80

The following table presents the estimated fair values and gross unrealized losses on AFS and HTM investments that were in a continuous loss position that was considered temporary, by length of time that an individual security in each category has been in a continuous loss position as of the dates indicated:

At December 31, 2019 and 2018, unrealized losses within the AFS and HTM investment portfolios were reflective of current interest rates in excess of the yield received on debt investments and were not indicative of an overall change in credit quality or other factors. At December 31, 2019 and 2018, gross unrealized losses on the Company's AFS and HTM investments were 1% and 3%, respectively, of their respective fair values.

At December 31, 2019, the Company had the intent and ability to retain its debt investments that were in an unrealized loss position at December 31, 2019, until the decline in value has recovered.

The loan balances for each portfolio segment presented above are net of their respective net unamortized fair value mark discount on acquired loans and net unamortized loan origination costs for the dates indicated:

	December 31,
(In thousands)	2019			2018

Net unamortized loan origination costs	(3,111		)	(1,865		)
Total	$	(518	)	$	2,071

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

83

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.

The HPFC loan portfolio is an acquired loan portfolio. It consists of niche commercial lending to the small business medical field, including dentists, optometrists and veterinarians across the U.S. The ability and willingness of borrowers to honor their repayment commitments is generally dependent on the success of the borrower's business. In 2016, the Company closed HPFC's operations and is no longer originating HPFC 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, 2019 and 2018, outstanding loans to certain officers, directors and their associated companies was less than 5% of the Company's shareholders' equity.

The ALL is management’s best estimate of the inherent risk of loss in the Company’s loan portfolio as of the consolidated statement of condition date. Management makes various assumptions and judgments about the collectability of the loan portfolio and provides an allowance for potential losses based on a number of factors including historical losses. If those assumptions are incorrect, the ALL may not be sufficient to cover losses and may cause an increase in the allowance in the future. Among the factors that could affect the Company’s ability to collect loans and require an increase to the allowance in the future are: (i) financial condition of borrowers; (ii) real estate market changes; (iii) state, regional, and national economic conditions; and (iv) a requirement by federal and state regulators to increase the provision for loan losses or recognize additional charge-offs.

The Company completed its annual ALL policy review in the fourth quarter of 2019, and no significant changes to its ALL methodology were made.

The Board of Directors monitors credit risk through the Directors' Loan Review Committee, which reviews large credit exposures, monitors external loan reviews, 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, concentration levels, and the ALL methodology. Credit Risk Administration and the Credit Risk Policy Committee oversee the Company's systems and procedures to monitor the credit quality of its loan portfolio, conduct a loan review program, maintain the integrity of the loan rating system, determine the adequacy of the ALL and support the oversight efforts of the Directors' Loan Review Committee and the Board of Directors. The Company's practice is to manage the portfolio proactively such that management can identify problem credits early, assess and 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.

For purposes of determining the ALL, the Company disaggregates its loans into portfolio segments, which include residential real estate, commercial real estate, commercial, home equity, consumer and HPFC. Each portfolio segment possesses unique risk characteristics that are considered when determining the appropriate level of allowance. These risk characteristics unique to each portfolio segment include the following:

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.

Commercial Real Estate. Commercial real estate loans consist of mortgage loans to finance investments in real property such as multi-family residential, commercial/retail, office, industrial, hotels, educational, health care 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. Loan-to-value ratios at origination are governed by established policy and regulatory guidelines. Commercial real estate loans are primarily paid by the cash flow generated from the real property, such as operating leases, rents, or other operating cash flows from the borrower.

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

84

applicable. Commercial loans are primarily paid by the operating cash flow of the borrower. Commercial loans may be secured or unsecured.

Home Equity. Home equity loans and lines are made to qualified individuals for legitimate purposes 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. Consumer loans may be secured or unsecured.

HPFC. Prior to the Company's closing of HPFC's operations in 2016, it provided commercial lending to dentists, optometrists and veterinarians, many of which were start-up companies. HPFC's loan portfolio consists of term loan obligations extended for the purpose of financing working capital and/or purchase of equipment. Collateral consists of pledges of business assets including, but not limited to, accounts receivable, inventory, and/or equipment. These loans are primarily paid by the operating cash flow of the borrower and the original terms ranged from seven to ten years.

(1) The provision (credit) for loan losses excludes any impact for the change in the reserve for unfunded commitments, which represents management's estimate of the amount required to reflect the probable inherent losses on outstanding letters of credit and unused lines of credit. The reserve for unfunded commitments was presented within accrued interest and other liabilities on the consolidated statements of condition. At December 31, 2019, 2018, and 2017, the reserve for unfunded commitments was $21,000, $22,000 and $20,000, respectively.

The following table reconciles the provision for loan losses to the provision for credit losses as presented on the consolidated statement of income for the periods indicated:

	For the Year Ended December 31,
(In thousands)	2019			2018		2017
Provision for loan losses	$	2,862		$	845	$	3,026
Change in reserve for unfunded commitments	(1		)	2		9
Provision for credit losses	$	2,861		$	847	$	3,035

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 ensure that credit concentrations can be effectively identified, all commercial and commercial real estate loans are assigned Standard Industrial Classification codes, North American Industry Classification System codes, and state and county codes. Shifts in portfolio concentrations are monitored. As of December 31, 2019, the Company's total exposure to the lessors of nonresidential buildings' industry was 12% of total loans and 31% of total commercial real estate loans. There were no other industry concentrations exceeding 10% of the Company's total loan portfolio as of December 31, 2019.

87

 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, commercial real estate, residential real estate, and HPFC loans 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 ALL:

• 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.

Asset quality indicators are periodically reassessed to appropriately reflect 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.

The Company closely monitors the performance of its loan portfolio. A loan is placed on non-accrual status when the financial condition of the borrower is deteriorating, payment in full of both principal and interest is not expected as scheduled or principal or interest has been in default for 90 days or more. Exceptions may be made if the asset is secured by collateral sufficient to satisfy both the principal and accrued interest in full and collection is reasonably assured. When one loan to a borrower is placed on non-accrual status, all other loans to the borrower are re-evaluated to determine if they should also be placed on non-accrual status. All previously accrued and unpaid interest is reversed at this time. A loan will return to accrual status when collection of principal and interest is assured and the borrower has demonstrated timely payments of principal and interest for a reasonable period, generally at least six months. Unsecured loans, however, are not normally placed on non-accrual status because they are 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 a summary of non-accrual loans, which include TDRs, and loans past due over 90 days and accruing as of the following dates:

Interest income that would have been recognized if loans on non-accrual status had been current in accordance with their original terms for the year ended December 31, 2019, 2018, and 2017 is estimated to have been $420,000, $600,000, and $843,000, respectively.

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 ALL for the dates indicated:

NOTE 6 – LEASES

Effective January 1, 2019, the Company adopted the new lease accounting standard, ASU 2016-02, using the modified retrospective method. As such, for reporting periods beginning on or after January 1, 2019, leases are recognized, presented and disclosed in accordance with ASU 2016-02, while periods prior to the adoption date were not adjusted and are reported in accordance with ASC 840, Leases ("ASC 840"). Refer to Note 1 for further details.

The Company enters into noncancellable lease arrangements primarily for its office buildings and 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. Many of these lease arrangements provide the Company with the option to renew the lease arrangement after the initial lease term. These options are included in determining the lease

93

term used to establish the right-of-use assets and lease liabilities, when it is reasonably certain the Company will exercise its renewal option. As most of the Company's leases do not have a readily determinable implicit rate, the incremental borrowing rate is primarily used to determine the discount rate for purposes of measuring the right-of-use assets and lease liabilities. 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 Company Director serves as the Chairman and Chief Executive Officer of the other company. The term of the lease is through 2022.

The following right-of-use assets and lease liabilities have been reported within other assets and other liabilities on the consolidated statements of condition for the period indicated:

At December 31, 2019 and 2018, the Company had identified and designated loans with an unpaid principal balance of $11.9 million and $4.3 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, 2019 and 2018, the unrealized (loss) gain recorded was ($61,000) and $89,000, 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 year ended December 31, 2019, 2018 and 2017 was the change in unrealized (losses) gains on loans held for sale of ($150,000), $52,000 and $326,000, 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 year ended December 31, 2019, 2018 and 2017, net unrealized gains (losses) from the change in fair value on its forward delivery commitments were $282,000, ($127,000), and ($136,000), respectively. Refer to Note 12 for further discussion of the Company's forward delivery commitments.

Servicing Assets

At December 31, 2019 and 2018, the Company's unpaid principal balances on its servicing assets were $227.8 million and $235.4 million, respectively.

For the year ended December 31, 2019, 2018 and 2017, the Company recorded servicing fee income for its servicing assets of $898,000, $949,000 and $1.0 million, respectively, and 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, 2019 and 2018 was $877,000 and $831,000, respectively. 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, 2019 and 2018, the prepayment assumption used within the valuation model was 14.4% and 11.5%, respectively, and the discount rate was 11.2% and 11.1%. The estimated effect of a 10% and 20% increase to the prepayment assumption at December 31, 2019 was a decrease of $65,000 and $126,000, respectively, while a 100 and 200 basis point increase to the discount rate assumption was a decrease of $47,000 and $90,000. Other assumptions include, but are not limited to, delinquency rates, foreclosure rates, and loan servicing cost.

Servicer and Sub-Servicer Net Worth and Liquidity Requirements

The Bank, as a servicer and sub-servicer of loans, must maintain certain net worth and liquidity requirements for certain secondary market investors, including HUD, FNMA and FHLMC.

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 but would not materially affect the Company's consolidated financial statements.

At December 31, 2019 and 2018, 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, 2019 and 2018.

The Company's outstanding FHLBB borrowings at December 31, 2019 and 2018 did not contain any call options.

FHLBB borrowings 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

99

and other qualified assets. The carrying value of residential real estate and commercial loans pledged as collateral was $1.4 billion and $1.1 billion at December 31, 2019 and 2018. The carrying value of investment securities pledged as collateral at the FHLBB was $150,000 and $172,000 at December 31, 2019 and 2018, respectively.

Subordinated Debentures

The Company issued $15.0 million of subordinated debt on October 8, 2015, which qualifies as Tier 2 regulatory capital. The interest rate on the subordinated debt is 5.50% per annum, fixed for the ten-year term and payable semi-annually on April 15 and October 15 each year. The Company can redeem the subordinated debt at par starting on October 15, 2020 plus accrued and unpaid interest, or earlier if (i) they no longer qualify as Tier 2 capital for regulatory capital purposes; (ii) a change in law that prevents the Company from deducting interest payable for U.S. federal income tax purposes, or (iii) the Company is required to register as an investment company pursuant to the Investment Company Act of 1940. The subordinated debt is scheduled to mature on October 15, 2025.

The Company incurred certain costs associated with the issuance of $15.0 million of subordinated debt. The Company capitalized these costs and they have been presented within subordinated debentures on the consolidated statements of condition. At December 31, 2019 and 2018, net debt issuance costs were $251,000 and $366,000, respectively. Debt issuance costs amortize over the expected life of the related debt. For the year ended December 31, 2019 and 2018 the amortization expense for debt issuance costs were $115,000 and $54,000, respectively, and were recognized as an increase to interest expense within the consolidated statements of income.

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. At December 31, 2019 and 2018, the interest rate on the trust preferred securities was 3.36% and 4.20%, 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 the average three-month LIBOR plus 1.42%. At December 31, 2019 and 2018, the interest rate on the trust preferred securities was 3.41% and 3.86%, 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, 2019, $43.0 million of the trust preferred securities were included in the Company’s total Tier 1 capital and amounted to 10.3% of Tier 1 capital of the Company.

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 $3.3 million, $3.4 million, and $3.4 million for the year ended December 31, 2019, 2018 and 2017, 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, 2019, 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, 2019 and 2018. 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 18, 2020 for which the interest rate is LIBOR-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 $114.7 million through the FRB's Discount Window for which the interest rate is set by the FRB daily. At December 31, 2019, the Bank pledged commercial loans with a carrying value of $161.5 million and investment securities of $13,000.

NOTE 10 – REPURCHASE AGREEMENTS

The Company can raise additional liquidity by entering into repurchase agreements at its discretion. In a security repurchase agreement transaction, the Company will generally sell a security, agreeing to repurchase either the same or 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 statement of income. The securities underlying the agreements are delivered to counterparties as security for the repurchase obligations. Since 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 tables 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)	2019		2018
Customer Repurchase Agreements(1)(2):
Collateralized mortgage obligations issued or guaranteed by U.S. government-sponsored enterprises	$	118,969	$	118,823
Mortgage-backed securities issued or guaranteed by U.S. government-sponsored enterprises	117,654		125,590
Obligations of states and political subdivisions	1,361		1,455
Total	$	237,984	$	245,868

(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.

Certain customers held CDs totaling $1.0 million and $923,000 at December 31, 2019 and 2018, 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.

NOTE 11 – 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 for the dates indicated:

	December 31,
(In thousands)	2019		2018
Commitments to extend credit	$	734,649	$	654,575
Standby letters of credit	5,211		3,063
Total	$	739,860	$	657,638

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. Of the total commitments to extend credit, $274.6 million and $270.8 million were unconditionally cancellable by the Company at December 31, 2019 and 2018, respectively.

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.

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, we may be unable to estimate

reasonably possible losses with respect to every litigation matter we face.

As of December 31, 2019 and 2018, the Company did not have any material loss contingencies that were provided for and/or that are required to be disclosed.

NOTE 12 – DERIVATIVES AND HEDGING

The Company uses derivative financial instruments for risk management purposes (primarily interest rate risk) and not for trading or speculative purposes. The Company controls the credit risk associated with these derivative financial instruments through collateral, credit approvals and monitoring procedures.

102

Derivative financial instruments are carried at fair value on the consolidated statements of condition. The accounting for changes in the fair value of a derivative instrument is dependent upon whether or not it has been designated as a hedge for accounting purposes and, if so, the type of hedge it has been designated as. The changes in fair value of the Company's derivative instruments not designated as hedges are accounted for within the consolidated statements of income.

Quarterly, in conjunction with financial reporting, each cash flow hedge is assessed for ineffectiveness. To the extent ineffectiveness is identified, this amount is recorded within the consolidated statements of income. The gain or loss on the effective portion of the cash flow hedge is reclassified from AOCI into interest within the consolidated statements of income in the period the hedged transaction affects earnings.

Derivatives Not Designated as Hedges

Customer Loan Swaps

The Company will enter into interest rate swaps with its commercial customers to provide them with a means to lock into a long-term fixed rate, while simultaneously entering into an arrangement with a counterparty to swap the fixed rate to a variable rate to manage interest rate exposure effectively. As the interest rate swap agreements have substantially equivalent and offsetting terms, they do not materially change the Company's interest rate risk or present any material exposure to its consolidated statements of income. Customer loan swaps are presented on a gross basis within other assets and accrued interest and other liabilities on the consolidated statements of condition.

The following table presents the total positions, notional and fair value of the Company's customer loans swaps with each party for the dates indicated:

		December 31,
		2019						2018
(In thousands, except number of positions)	Presentation on Consolidated Statements of Condition	Number of Positions	Notional Amount		Fair Value			Number of Positions	Notional Amount		Fair Value
Receive fixed, pay variable	Accrued interest and other liabilities	10	$	45,243	$	(514	)	57	$	297,624	$	(7,841	)
Receive fixed, pay variable	Other assets	75	366,351		17,756			25	118,891		3,467
Pay fixed, receive variable	(Accrued interest and other liabilities)/other assets	85	411,594		(17,242		)	82	416,515		4,374
Total		170	$	823,188	$	—		164	$	833,030	$	—

The Company mitigates its customer counterparty credit risk exposure through its loan policy and underwriting process, which includes credit approval limits, monitoring procedures, and obtaining collateral, where appropriate. The Company mitigates its institutional counterparty credit risk exposure by limiting the institutions for which it will enter into interest swap arrangements through an approved listing by its Board of Directors.

The Company has entered into a master netting arrangement with its institutional counterparty and settles payments with the counterparty as necessary. The Company's arrangement with its institutional counterparty requires it to post cash or other assets as collateral for its contracts in a net liability position based on their aggregate fair value and the Company's credit rating. The Company may also receive cash collateral for contracts in a net asset position as requested. At December 31, 2019, the Company posted $18.4 million of cash as collateral and it was presented within other assets on the consolidated statements of condition. At December 31, 2018, the institutional counterparty posted $5.1 million of cash as collateral and it was presented within interest-bearing deposits in other banks as restricted cash with a matching liability within accrued interest and other liabilities on the consolidated statements of condition. Refer to Note 13 for further discussion of master netting arrangements and presentation within the Company's consolidated financial statements.

103

Fixed-Rate Mortgage Interest Rate Locks 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. The Company's pipeline of mortgage loans with fixed-rate interest rate lock commitments for which it intends to sell the loan upon origination was as follows for the dates indicated:

		December 31,
		2019					2018
(In thousands)	Presentation on Consolidated Statements of Condition	Notional Amount		Fair Value			Notional Amount		Fair Value
Fixed-rate mortgage interest rate locks	Other assets	$	27,087	$	480		$	8,239	$	95
Fixed-rate mortgage interest rate locks	Accrued interest and other liabilities	2,519		(18		)	3,838		(28		)
Total		$	29,606	$	462		$	12,077	$	67

For the year ended December 31, 2019, 2018 and 2017, the net unrealized gain (loss) from the change in fair value on the Company's fixed-rate mortgage rate locks reported within mortgage banking income, net, on the consolidated statements of income was $395,000, ($218,000), and $98,000, respectively.

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 has been 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.

The Company's forward delivery commitments on loans held for sale for the dates indicated were as follows:

		December 31,
		2019					2018
(In thousands)	Presentation on Consolidated Statements of Condition	Notional Amount		Fair Value			Notional Amount		Fair Value
Forward delivery commitments ("best effort")	Other assets	$	10,846	$	312		$	2,593	$	32

Interest Rate Swap on Loans

On June 12, 2019, the Company entered into a $100.0 million interest rate swap contract with a counterparty to manage interest rate risk associated with its variable-rate loans. The Company has entered into a master netting arrangement with its institutional counterparty and settles payments monthly on a net basis. The arrangement with the institutional counterparty requires it to post collateral for its interest rate swap on loans when it is in a net liability position based on its fair value. If the interest rate swap is in a net asset position based on its fair value, the institutional counterparty will post collateral to the Company as requested. At December 31, 2019, the institutional counterparty posted $560,000 of cash as collateral, which was presented within interest-bearing deposits in other banks as restricted cash with a matching liability within accrued interest and other liabilities on the consolidated statements of condition. Refer to Note 13 for further discussion of master netting arrangements and presentation within the Company's consolidated financial statements.

Junior Subordinated Debt Interest Rate Swaps

The Company entered into five interest rate swap agreements with an institutional counterparty to manage interest rate risk associated with the Company's variable rate borrowings. The Company has entered into a master netting arrangement with its institutional counterparty and settles payments quarterly on a net basis. The interest rate swap arrangements contain provisions that require the Company to post cash or other assets as collateral with the counterparty for contracts that are in a net liability position based on their aggregate fair value and the Company’s credit rating. If the interest rate swaps are in a net asset position based on their aggregate fair value, the institutional counterparty will post collateral to the Company as requested. At December 31, 2019 and 2018, the Company posted $8.8 million and $5.8 million, respectively, of cash as collateral to the institutional counterparty, which is presented within other assets on the consolidated statements of condition. Refer to Note 13 for further discussion of master netting arrangements and presentation within the Company's consolidated financial statements.

NOTE 14 – 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

107

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 guidelines apply to the Company on a consolidated basis.

Under the current guidelines, 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, four quarter trailing net income, net of distributions and tax effects not reflected in net income).

The Company and Bank's risk-based capital ratios exceeded regulatory requirements, including the capital conservation buffer, at December 31, 2019 and 2018, and the Bank's capital ratios met the requirements for the Bank to be considered "well capitalized" under prompt correct action provisions for each period. There were no changes to the Company or Bank's capital ratios that occurred subsequent to December 31, 2019 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, 2019				Minimum Regulatory Capital Required for Capital Adequacy plus Capital Conservation Buffer		Minimum Regulatory Provision To Be "Well Capitalized" Under Prompt Corrective Action Provisions		December 31, 2018				Minimum Regulatory Capital Required For Capital Adequacy plus Capital Conservation Buffer		Minimum Regulatory Provision To Be "Well Capitalized" Under Prompt Corrective Action Provisions

In 2015, the Company issued $15.0 million of subordinated debentures, and in 2006 and 2008, it issued $43.0 million of junior subordinated debentures in connection with the issuance of trust preferred securities. Although the subordinated debentures and 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, subject to certain limits, each within its calculation of risk-based capital. At December 31, 2019 and 2018, $15.0 million of subordinated debentures were included as Tier 2 capital and were included in the calculation of the Company's total risk-based capital, and, at December 31, 2019 and 2018, $43.0 million of the junior subordinated debentures were included in Tier 1 and total risk-based capital for the Company. The Company's $15.0 million of subordinated debentures are subject to phase-out of 20% annually beginning on its six year anniversary, and 20% a year thereafter until it is fully phased out.

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 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 regulations prescribed by the OCC, without prior OCC approval, a bank subsidiary may not declare dividends in any year in excess of the bank’s (i) net income for the current year, (ii) plus its retained net income for the prior two years.

For the year ended December 31, 2019, 2018, and 2017, the Bank declared dividends for payment to the Company in the amount of $36.9 million, $28.1 million, and $16.8 million, respectively. For the year ended December 31, 2019, 2018 and 2017, the Company declared $18.9 million, $18.0 million and $14.6 million, respectively, in dividends payable to its shareholders.

Common Stock Repurchase

In September 2013, the Company's Board of Directors authorized the 2013 Repurchase Plan which allowed for the repurchase of up to 375,000 shares of the Company’s outstanding common stock. During the year ended December 31, 2018, the Company purchased the remaining 750 shares of its common stock and completed its repurchase of the total allotment of 375,000 shares at a weighted-average price of $26.57.

In January 2019, the Company's Board of Directors authorized the purchase of up to 775,000 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, 2018. For the year ended December 31, 2019, the Company purchased 488,052 shares of its common stock at a weighted-average price of $42.61. This program is now closed.

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. This program replaces the 2019 program and is open for 12 months.

NOTE 16 – REVENUE FROM CONTRACTS WITH CUSTOMERS

On January 1, 2018, the Company adopted ASC 606, the new revenue recognition standard,using the modified retrospective transition method.

A portion of the Company's non-interest income is derived from contracts with customers, and as such, the revenue recognized depicts the transfer of promised goods or services to its customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The Company considers the terms of the contract and all relevant facts and circumstances when applying this guidance.

The Company has disaggregated its revenue from contracts with customers into categories based on the nature of the revenue. The categorization of revenues from contracts with 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 December 31,
(In thousands)	Income Statement Line Item	2019		2018
Debit card interchange income	Debit card income	$	9,701	$	9,067
Services charges on deposit accounts	Service charges on deposit accounts	8,393		8,253
Fiduciary services income	Income from fiduciary services	5,901		5,376
Investment program income	Brokerage and insurance commissions	2,625		2,615
Other non-interest income	Other income	1,710		1,508
Total non-interest income within the scope of ASC 606		28,330		26,819
Total non-interest income not in scope of ASC 606		13,783		11,357
Total non-interest income		$	42,113	$	38,176

111

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 year ended December 31, 2019 and 2018, cash rewards totaled $554,000 and $438,000, respectively.

• Service charges on deposit accounts:Deposit-related fees, include, but are not limited to, overdraft income, service charge income, and other fees generated by the depositor relationship with the Company. For each depositor relationship, an agreement and related disclosures outline the terms of the contract between the depositor and the Bank, including the assessment of fees and fee structure for its various products. The contract 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.

• Fiduciary services income:The Company, through its wealth management and trust services department, doing business as Camden National Wealth Management, earns fees for its investment management and related services for its clients. Fees earned for its services are largely dependent on assets under management as of the last day of the month and do not contain performance clauses. Should the applicable services contract be terminated by either party, fees for services are earned up to the effective date of contract termination. As such, fiduciary services income is earned and recognized daily.

• Investment program income:Under an investment program offered by the Company, doing business as Camden Financial Consultant (“Program”), its clients are provided access to brokerage, advisory and insurance products offered through an unaffiliated third party. Certain Company employees are registered securities representatives and/or registered investment advisor representatives of the third party, operating in such capacity under Camden Financial Consultants to provide clients with brokerage, investment advisory and insurance related services. The Company receives a portion of the commissions and fees received by the unaffiliated third party brokerage firm from the sale of investment products and investment advisory services, in accordance with the terms of the contract between the two parties.

The revenues earned by the Company are net of administrative expenses and the portion retained by the unaffiliated third party brokerage firm. The Company does not have control of the specified services provided to its clients by the unaffiliated third party brokerage firm under the Program. Revenues earned from Program-related services are presented on the consolidated statements of income on a net basis.

NOTE 17 – STOCK-BASED COMPENSATION PLANS

Stock-Based Compensation

On April 29, 2003 and May 1, 2012, the shareholders of the Company approved the 2003 Plan and 2012 Plan, respectively. The maximum number of shares of stock reserved and available for issuance under each the 2003 Plan and 2012 Plan is 1.2 million shares. As shares or units are vested or options are exercised, new shares are issued out of either the 2003 or 2012 Plan. Awards may be granted in the form of incentive stock options, non-qualified stock options, stock appreciation rights, restricted stock, restricted stock units, unrestricted stock, performance shares and dividend equivalent rights, or any combination of the preceding, and the exercise price will not be less than 100% of the fair market value on the date of grant in the case of incentive stock options, or 85% of the fair market value on the date of grant in the case of non-qualified stock options. No stock option is exercisable more than ten years after the date the stock option was granted. The exercise price of all options granted equaled the market price of the Company's stock on the date of grant, except for certain non-qualified stock options that were issued in conjunction with an acquisition.

The amount of cash used to settle stock-based compensation transactions for the year ended December 31, 2019, 2018 and 2017 was $455,000, $848,000 and $902,000, respectively.

Stock Option Awards

Stock options granted under the 2003 Plan and the 2012 Plan include both incentive stock options and non-qualified stock options. Incentive stock options and non-qualified stock options granted vest pro-rata over a five year period, or earlier if an employee retires and has met the retirement eligibility requirements of the plan, and have a contractual life of ten years.

On the date of each grant, the fair value of each award is derived using the Black-Scholes option pricing model based on assumptions made by the Company as follows:

• Dividend yield is based on the dividend rate of the Company’s stock at the date of grant.

• Risk-free interest rate is based on the U.S. Treasury bond rate with a term equaling the expected life of the granted options.

• Expected volatility is based on the historical volatility of the Company’s stock price calculated over the expected life of the option.

• Expected life represents the period of time that granted options are expected to be outstanding based on historical trends.

For the year ended December 31, 2019, 2018 and 2017, the Company issued stock options with a grant-date fair value of $0, $8,000 and $0, respectively. The following table presents the option pricing assumptions and the estimated fair value of the options using these assumptions for grants made for the year ended:

	December 31,
	2019	2018			2017
Weighted-average dividend yield	N/A	2.36		%	N/A
Weighted-average risk-free interest rate	N/A	2.38		%	N/A

Weighted-average expected life (in years)	N/A	5.3			N/A
Weighted-average fair value of options granted	N/A	$	7.78		N/A

For the year ended December 31, 2019, 2018 and 2017, the compensation expense recognized was $7,000, $10,000 and $20,000, respectively. The Company does not receive any tax benefit on its issuance of incentive stock options, unless upon exercise a disqualifying disposition is made. The total tax benefit to the Company upon exercise of incentive stock options for the year ended December 31, 2019, 2018 and 2017 was $8,000, $50,000, and $21,000, respectively.

DCRP

The DCRP is an unfunded deferred compensation plan for the benefit of certain Company executives. Annually, participants will receive a credit to an account administered by the Company of 10% of each participant’s annual base salary and bonus for the prior performance period.

	SERP						Other Postretirement Benefits
	2019		2018		2017		2019		2018		2017
Weighted-average assumptions as of end of year:

(1) On December 22, 2017, the Tax Act was enacted, reducing the U.S. federal corporate income tax rate from 35.0% to 21.0%. The Company recognized the effect of the tax law changes in the period of enactment, which resulted in a reduction to net deferred tax assets and a corresponding charge to income tax expense of $14.3 million.

At December 31, 2019 and 2018, the Company had $48.2 million and $52.1 million, respectively, in unused federal net operating losses that were acquired in 2015. 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, 2019 and 2018 determined that no valuation allowance was necessary.

As of December 31, 2019, the Company's federal and state income tax returns for the year ended December 31, 2018, 2017 and 2016 were open to audit by federal and state authorities.

NOTE 20 – EPS

The following is an analysis of the calculation of basic and diluted EPS, reflecting the application of the two-class method, for the periods indicated:

	For The Year Ended December 31,
(In thousands, except number of shares and per share data)	2019			2018			2017
Net income	$	57,203		$	53,071		$	28,476
Dividends and undistributed earnings allocated to participating securities(1)	(120		)	(148		)	(118		)
Net income available to common shareholders	$	57,083		$	52,923		$	28,358
Weighted-average common shares outstanding for basic EPS	15,407,289			15,571,387			15,509,665
Dilutive effect of stock-based awards(2)	45,733			54,916			78,682
Weighted-average common and potential common shares for diluted EPS	15,453,022			15,626,303			15,588,347
Earnings per common share:
Basic EPS	$	3.70		$	3.40		$	1.83
Diluted EPS	$	3.69		$	3.39		$	1.82

(1) Represents dividends paid and undistributed earnings allocated to nonvested stock-based awards that contain non-forfeitable rights to dividends.

(2) Represents the effect of the assumed exercise of stock options, vesting of restricted shares and restricted stock units, and issuance of LTIP awards that have met the performance criteria, utilizing the treasury stock method.

122

For the year ended December 31, 2019, 2018 and 2017 there were no anti-dilutive stock based awards that have been excluded from the computation of potential common shares for purposes of calculating diluted EPS, because the average market price of the Company's common stock is greater than the exercise prices.

Nonvested 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 nonvested 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 nonvested 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.

NOTE 21 – 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

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.

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.

123

Equity Securities: The fair value of equity securities in bank stock is determined using market prices based on recent trading activity and dealer quotes. These equity securities are traded on inactive markets and are 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 by the Company and its counterparties. As of December 31, 2019 and 2018, the Company has assessed the significance of the impact of the credit valuation adjustments on the overall valuation of its derivative positions and has determined that the credit valuation adjustments are not significant to the overall valuation of its derivatives due to collateral postings.

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.

124

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:

The Company did not have any transfers between Level 1 and Level 2 of the fair value hierarchy for the year ended December 31, 2019. 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.

125

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. 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.

Collateral-Dependent Impaired Loans:  Loans for which it is probable that payment of interest and principal will not be made in accordance with the contractual terms of the loan agreement are considered impaired. The Company's policy is to individually evaluate for impairment loans with a principal balance of $500,000 or more, that are classified as substandard or doubtful and are on non-accrual status. Once the population of loans is identified for individual impairment assessment, the Company measures these loans for impairment by comparing net realizable value, which is the fair value of the collateral, less estimated costs to sell, to the carrying value of the loan. If the net realizable value of the loan is less than the carrying value of the loan, then a loss is recognized as part of the ALL to adjust the loan's carrying value to net realizable value. Accordingly, certain collateral-dependent impaired loans are subject to measurement at fair value on a non-recurring basis. Management has estimated 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. At December 31, 2019 and 2018, the Company's mortgage servicing assets were not carried at fair value.

Non-Financial Instruments Recorded at Fair Value on a Non-recurring Basis

The Company has no non-financial assets or non-financial liabilities measured at fair value on a recurring basis. Non-financial assets measured at fair value on a non-recurring basis consist of OREO, goodwill and core deposit intangible assets.

OREO:OREO properties acquired through foreclosure or deed in lieu of foreclosure are recorded at net realizable value, which is the fair value of the real estate, less estimated costs to sell. Any write-down of the recorded investment in the related loan is charged to the ALL 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 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.

Goodwill and Core Deposit Intangible Assets: Goodwill represents the excess cost of an acquisition over the fair value of the net assets acquired. The fair value of goodwill is estimated by utilizing several standard valuation techniques, including discounted cash flow analyses, bank merger multiples, and/or an estimation of the impact of business conditions and investor activities on the long-term value of the goodwill. Should an impairment occur, the associated goodwill is written-down to fair value and the impairment charge is recorded within non-interest expense in the consolidated statements of income. The Company conducts an annual impairment test of goodwill in the fourth quarter each year, or more frequently as necessary. There have been no indications or triggering events for the year ended December 31, 2019 or 2018 for which management believed that it was more-likely-than-not that goodwill is impaired.

The Company's core deposit intangible assets represent the estimated value of acquired customer relationships and are 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. There were no indications or triggering events for the year ended December 31, 2019 or 2018 that indicated the carrying amount may not be recoverable.

We have audited the accompanying consolidated statements of condition of Camden National Corporation and Subsidiary (the Company) as of December 31, 2019 and 2018, the related consolidated statements of income, comprehensive income, changes in shareholders’ equity and cash flows for each of the three years in the period ended December 31, 2019, and the related notes to the consolidated financial statements (collectively, the financial statements). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2019 and 2018, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2019, in conformity with accounting principles generally accepted in the United States of America.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company's internal control over financial reporting as of December 31, 2019, based on criteria established in Internal Control - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission in 2013, and our report dated March 11, 2020 expressed an unqualified opinion on the effectiveness of the Company's internal control over financial reporting.

Basis for Opinion

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Report of Independent Registered Public Accounting Firm

To the Shareholders and Board of Directors

Camden National Corporation

Opinion on the Internal Control Over Financial Reporting

We have audited Camden National Corporation and Subsidiary’s (the Company) internal control over financial reporting as of December 31, 2019, based on criteria established in Internal Control - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission in 2013. In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2019, based on criteria established in Internal Control - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission in 2013.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated statements of condition of the Company as of December 31, 2019 and 2018, and the related consolidated statements of income, comprehensive income, changes in shareholders’ equity and cash flows for each of the three years in the period ended December 31, 2019, and our report dated March 11, 2020 expressed an unqualified opinion.

Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting in the accompanying Management’s Annual Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control Over Financial Reporting

A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the company's assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Item 9. Changes in and Disagreements with Accountants on Accounting and Financial Disclosure

Not applicable.

Item 9A. Controls and Procedures

As required by Rule 13a-15 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), the Company’s management conducted an evaluation with the participation of the Company’s Chief Executive Officer and Chief Operating Officer and Chief Financial Officer & Principal Financial and Accounting Officer, regarding the effectiveness of the Company’s disclosure controls and procedures, as of the end of the last fiscal year. In designing and evaluating the Company’s disclosure controls and procedures, the Company and its management recognize that any controls and procedures, no matter how well designed and operated, can provide only a reasonable assurance of achieving the desired control objectives, and management necessarily was required to apply its judgment in evaluating and implementing possible controls and procedures. Based upon that evaluation, the Chief Executive Officer and Chief Operating Officer and Chief Financial Officer & Principal Financial and Accounting Officer concluded that they believe the Company’s disclosure controls and procedures are effective to ensure that information required to be disclosed by the Company in the reports it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms. We intend to continue to review and document our disclosure controls and procedures, including our internal controls and procedures for financial reporting, and we may from time to time make changes to the disclosure controls and procedures to enhance their effectiveness and to ensure that our systems evolve with our business.

There was no change in our internal control over financial reporting that occurred during the period covered by this Annual Report on Form 10-K that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

MANAGEMENT’S ANNUAL REPORT

ON INTERNAL CONTROL OVER FINANCIAL REPORTING

The Management of the Company is responsible for the preparation and fair presentation of the financial statements and other financial information contained in this Form 10-K. Management is also responsible for establishing and maintaining adequate internal control over financial reporting and for identifying the framework used to evaluate its effectiveness. Management has designed processes, internal controls and a business culture that foster financial integrity and accurate reporting. The Company’s comprehensive system of internal control over financial reporting was designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of the consolidated financial statements of the Company in accordance with accounting principles generally accepted in the United States of America. The Company’s accounting policies and internal control over financial reporting, established and maintained by management, is under the general oversight of the Company’s Board of Directors, including the Board of Directors’ Audit Committee.

Management has made a comprehensive review, evaluation, and assessment of the Company’s internal control over financial reporting as of December 31, 2019. The standard measures adopted by management in making its evaluation are the measures in Internal Control — Integrated Framework (2013) published by the Committee of Sponsoring Organizations of the Treadway Commission. Based upon its review and evaluation, management concluded that, as of December 31, 2019, the Company’s internal control over financial reporting was effective and that there were no material weaknesses. However, Management recognizes a control system, no matter how well designed and operated, has inherent limitations and can provide only reasonable, not absolute, assurance that the control system’s objectives will be met and may not prevent or detect all error and fraud. Therefore, even a system determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation.

RSM US LLP, an independent registered public accounting firm, which has audited and reported on the consolidated financial statements contained in this Form 10-K, has issued its written attestation report on management’s assessment of the Company’s internal control over financial reporting which precedes this report.

Exhibit 4.1

DESCRIPTION OF CAPITAL STOCK

A brief summary of the material terms of our capital stock is set forth below. The description is qualified in its entirety by reference to our Articles of Incorporation, as amended (the “Articles”) and Amended and Restated Bylaws (the “Bylaws”) that are filed as exhibits to the Form 10-K of which this Exhibit is a part. The following description of our capital stock and provisions of our Articles and Bylaws is only a summary of such provisions and instruments, and does not purport to be complete. As used in this Exhibit, the terms “Camden National Corporation,” “Camden,” the “Company,” “we,” “us,” “our,” and other similar references refer only to Camden National Corporation and not to any of its subsidiaries.

Authorized Capital Stock

Our authorized capital stock consists of 40,000,000 shares of common stock, without par value (the “common stock”). The number of authorized shares of our common stock may be increased or decreased (but not below the number of shares then outstanding) by the affirmative vote of a majority of our stock entitled to vote. At this time, we are not authorized under the terms of our Articles to issue any class or series of preferred stock, and we have no shares of preferred stock issued or outstanding.

Common Stock

The following is a description of the material terms and provisions of our common stock. See the Articles and Bylaws for a more complete description of the terms of our common stock.

General

As of December 31, 2019, we had 15,144,719 shares of common stock issued and outstanding. All shares of common stock will, when issued, be duly authorized, fully paid and nonassessable.

Dividends

Subject to the preferential rights of any other class or series of stock, holders of shares of our common stock will be entitled to receive dividends out of funds legally available for distribution, if and when they are authorized and declared by our board of directors, in such amounts as our board of directors may determine.

Our ability to pay dividends on our common stock:

• depends primarily upon the ability of our subsidiary, Camden National Bank, to pay dividends or otherwise transfer funds to us; and

• is subject to policies established by our banking regulators (see “Item 1. Business - Supervision and Regulation” of the Form 10-K of which this Exhibit is a part for a more detailed description of limitations on our ability to pay dividends).

Liquidation Rights

In the event we are liquidated, dissolved or our affairs are wound up, after we pay or make adequate provision for all of our known debts and liabilities, each holder of common stock will receive dividends pro rata out of assets that we can legally use to pay distributions, subject to any rights that are granted to the holders of any class or series of preferred stock.

Preemptive, Redemption, and Conversion Rights

The holders of our common stock do not have any preemptive rights. There are no subscription, redemption, conversion or sinking fund provisions with respect to our common stock.

Voting Rights

Except as otherwise required by law and except as provided by the terms of any other class or series of stock, holders of common stock have the exclusive power to vote on all matters presented to our stockholders, including the election of directors. Holders of common stock are entitled to one vote per share.

Generally, matters to be voted on by our stockholders must be approved by a majority of the votes cast at a meeting of stockholders in which a quorum is present, including the election of directors in an uncontested election, subject to state law

Exhibit 4.1

and any voting rights granted to any holders of preferred stock. In any meeting in which directors are to be elected, however, if the number of nominees exceeds the number of directors to be elected, directors will be elected by a plurality of the votes cast.

Other Rights

Subject to the preferential rights of any other class or series of stock, all shares of common stock have equal dividend, distribution, liquidation and other rights, and have no preference, appraisal or exchange rights, except for any appraisal rights provided by Maine law.

Certain Anti-Takeover Provisions

Certain provisions of our Articles and Bylaws, and certain provisions of Maine law applicable to our business, may discourage or make more difficult a takeover attempt that a stockholder might consider in his or her best interest. These provisions may also adversely affect prevailing market prices for our common stock. We believe that the benefits of increased protection give us the potential ability to negotiate with the proponent of an unsolicited proposal to acquire or restructure us and outweigh the disadvantage of discouraging those proposals.

Classified Board

Our board of directors is divided into three classes, each of which serves until the third annual meeting of shareholders after their election, with one class being elected each year.

Advance Notice Provision

Our Bylaws require that shareholders provide the Company’s Secretary notice not less than 90 days nor more than 120 days before the first anniversary of the preceding year’s annual meeting for the purpose of nominating any director candidate. If the date of the annual meeting is advanced by more than 30 days before or delayed by more than 60 days after the preceding year’s annual meeting, notice will be timely if it is delivered not earlier than 120 days before and not later than 90 days before the annual meeting or 10 days after public announcement of the date of the annual meeting is first made.

Maine Business Corporation Act

As a Maine corporation, we are subject to the Maine Business Corporation Act (the “Act”), certain provisions of which may have an anti-takeover effect.

Section 702 of the Act

Section 702 of the Act provides that special meetings of shareholders may be called only (i) by a majority of the board of directors, (ii) by the person or persons authorized to do so by the Articles or Bylaws, or (iii) by the holders of at least 10% of all the votes entitled to be cast on any issue proposed to be considered at the special meeting. We may amend our Articles to fix a lower percentage, or a higher percentage not exceeding 25% of all the votes entitled to vote on any issue proposed to be considered, of the requisite holders to call a special meeting.

Section 1109 of the Act

Section 1109 of the Act is an antitakeover law that generally prohibits us from engaging in a “business combination” with an “interested shareholder” for a period of five years after the date of the transaction in which the person becomes an interested shareholder, unless either (1) the business combination is approved by our board of directors prior to that person becoming an interested shareholder or (2) subsequent to the date of the transaction in which the person becomes an interested shareholder, the business combination is approved by our board of directors and authorized by the holders of a majority of our outstanding voting stock not beneficially owned by the interested shareholder or any affiliate or associate of the interested shareholder or by persons who are either directors or officers and also employees of the Company.

An “interested shareholder” is any person, firm or entity that is directly or indirectly the beneficial owner of 25% or more of our outstanding voting stock, other than by reason of a revocable proxy given in response to a proxy solicitation conducted in accordance with the Exchange Act which is not then reportable on a Schedule 13D under the Exchange Act.

We may at any time amend our Articles or Bylaws, by vote of the holders of at least 66 2/3% of our voting stock, to elect not to be governed by Section 1109.

Exhibit 4.1

Section 1110 of the Act

Section 1110 of the Act generally provides our shareholders with the right to demand payment from a person or group of persons which become a “controlling person” of an amount equal to the fair value of each voting share in the Company held by the shareholder. A “controlling person” generally is defined to mean an individual, firm or entity (or group thereof) that has voting power over at least 25% of our outstanding voting shares. Such a demand must be submitted to the controlling person within 30 days after the controlling person provides required notice to our shareholders of the acquisition or transactions which resulted in such person or group becoming a controlling person.

The EIP is designed to:

• Attract and retain talent needed for the Company’s success

• Be competitive with the market

Plan Year

The EIP plan year follows the Company’s fiscal year, January 1^st to December 31^st.

Eligibility

Following is a summary of the general guidelines for eligibility to receive an award under the Program. The Committee may establish different or additional eligibility criteria from time to time and has the discretion to make all determinations under the Program.

• Eligibility each year may include members of the Executive team and other key positions, as identified by the CEO and approved by the Compensation Committee (“Committee”) for those on the Executive team. Selection as a participant in one year does not guarantee selection for participation in any future year.

• Participants must be employed by October 1^st of the plan year in order to be eligible for that year’s incentive. Employees hired between January 1^st and October 1^st will be eligible to receive a prorated award based on hire date. For example: if an employee were to be hired on May 1^st, the employee would be eligible to receive two-thirds of his or her eligible EIP, if any, for the plan year. Employees hired on or after October 1^st of a year are not eligible to receive an award under the Program for that year.

• Participants must be an active employee as of the award payout date to receive an award (for exceptions, see “Death or Disability”).

• Participant’s performance must be in good standing for the performance period and at the time of payment. Unless otherwise determined by the Committee, participants who terminate employment during the plan year will not be eligible to receive an award and participants who have given notice of resignation or terminate employment after the plan year and before payout are not eligible to receive the incentive award payment (see exceptions for Death or Disability below).

Incentive Opportunity

Each participant will have an annual target incentive opportunity based on the competitive market for his/her role as determined by the Committee. Unless otherwise determined by the Committee, the target incentive will reflect a percentage of base earnings for the plan year with actual award amounts, if any, to be determined by the Committee and varying based on performance. The maximum payout for each participant will be capped at 200% of his/her target opportunity.

Performance Measures and Payout Range

The incentive award payout may be based on annual Net Income Before Taxes (NIBT) as compared to budgeted NIBT or such other performance measure or measures as determined by the Committee. The Company’s annual budget includes an assumed incentive award payout at target for each participant, and, as the applicable performance measure exceeds or falls below the budgeted level the incentive pool is adjusted to ensure appropriate funding for the participants. The Committee may set forth on an appendix to this Program summary from time to time, an illustration of the EIP pool funding amount as a percentage of budget based on achievement of the applicable performance measure. Unless otherwise determined by the Committee, EIP pool funding will begin once the level of the applicable performance measure reaches 96% of budget (threshold), and threshold performance (or minimum acceptable performance) will fund the incentive pool at 50% of target. To fund the

Exhibit 10.23

incentive pool at target, unless otherwise determined by the Committee, performance measure achievement at 100% of budget is needed. To fund the maximum of the incentive pool, unless otherwise determined by the Committee, performance measure achievement of 110% of budget must be achieved. Applicable performance measure results may be adjusted for extraordinary, one-time or other events as determined and approved by the Committee.

Payout can vary from 0% for below threshold performance, 50% for threshold achievement, 100% for target achievement and 200% for stretch performance achievement. Performance between payout levels at or above threshold (i.e., threshold, target and stretch) will be calculated using straight line interpolation as determined by the Committee.

Individual Performance

Unless otherwise determined by the Committee, each participant’s payout will be based 60% on the Company’s financial results and 40% on each individual’s achievements, accomplishments and performance as measured by the CEO of the Company in his discretion, except that the Committee shall determine the CEO’s individual performance in its discretion.

The CEO, with approval from the Committee, may have discretion to provide additional individual funding above 40% for the individual component for exceptional individual performance.

In applying individual performance discretion, the CEO must remain cost neutral to the funding pool. Any additions to the pool may be requested and approved by the Committee.

Committee Discretion

The Committee reserves the right to apply discretion to all determinations it makes under the Program, including the payouts as needed to reflect business environment, market conditions, budgetary constraints, compliance, asset credit quality and risk management considerations. The Committee also reserves the right to amend, modify and adjust payouts as necessary.

Exhibit 10.23

EIP Terms and Conditions

______________________________________________________________________________________________________

Effective Date

This Program summary is applicable to EIP plan years beginning effective January 1, 2020. The Program will be reviewed from time to time as needed to ensure proper alignment with the Company’s business objectives. The Committee retains the rights as described below to amend, modify or discontinue the Program and this summary at any time during the specified period.

Program Administration; Program Changes

The Program is administered by the Committee. The Committee has the sole authority to interpret the Program and to make or nullify any rules and procedures, as necessary, for proper administration. Any determinations by the Committee will be final and binding on all participants. The Committee may, in its sole discretion, terminate, discontinue, amend or modify the Program. The Committee may exercise its discretion to delegate its authority under the Program to a subcommittee of its members or the CEO, and references to the Committee under this summary shall include any such delegees.

EIP Award Payments

Incentive awards under the EIP are payable in cash after the Committee reviews and approves the performance results and payouts. Awards will be paid by March 15^th of the year following the last day of the performance period. Each participant’s payout is calculated on base earnings for the applicable plan year. “Base earnings” means gross base salary or base wages paid to the participant during the plan year, excluding any other compensation or benefits. In order for any award to be paid, the funding of the incentive pool must be approved by the Committee and the payments to the Executive team (in aggregate and individually) must be approved by the Committee. Unless otherwise determined by the Committee, the participant must be employed on the date of payment and have satisfactory performance (as determined by the Committee).

Termination Due to Death or Disability

In the event of a participant’s death or termination of employment due to disability, the Company will pay to the participant or the participant’s estate, as applicable, the prorata portion of the incentive award that had been earned by the participant during his/her period of employment based on actual Company performance through the end of the performance period.

Clawback and Ethical Standards

Amounts paid or payable under the EIP will be subject to the Company’s clawback policy, as in effect from time to time. The altering, inflating, and/or inappropriate manipulation of performance/financial results or any other infraction of recognized ethical business standards by a participant, whether or not such actions would impact the level of payout under the Program, will subject the participant to disciplinary action up to and including termination of employment. In addition, any incentive award paid or payable under the Program to which the participant would otherwise be entitled or eligible will be subject to recoupment or forfeiture, as applicable.

Participants who have willfully engaged in any activity injurious to the Company will, upon termination of employment, death or disability, be obligated to repay any incentive award earned for the performance period in which the wrongful conduct occurred.

Miscellaneous

Neither this summary nor the existence of the Program will be deemed to give any participant the right to be retained in the employment of the Company, nor will the Program interfere with, limit or impede the right of the Company to terminate the employment of any participant at any time for any reason.

Incentive awards are considered taxable income to participants in the year paid and will be subject to withholding for required income and other applicable taxes.

Any rights accruing to a participant or his/her estate under the Program shall be solely those of an unsecured general creditor of the Company. Nothing contained in this summary, and no action taken pursuant to the provisions of this summary under the Program, will create or be construed to create a trust of any kind, or a pledge, or a fiduciary relationship between the Company, the Board of Directors, the Committee or management and the

Exhibit 10.23

participant or any other person. Nothing herein will be construed to require the Company to maintain any fund or to segregate any amount for a participant’s benefit.

The relationship between the participants and the Company is one of at-will employment. The Program does not alter the relationship. The Program and the awards and payments under the Program shall, in all respect, be governed by, and construed and enforced in accordance with the laws of Maine.

Exhibit 10.23

Appendix

The table below illustrates the incentive funding based on NIBT as it compares to budgeted NIBT. Funding will begin once NIBT reaches 96% of budget (threshold). Threshold performance (or minimum acceptable performance) will fund the incentive pool at 50% of target. To fund the incentive pool at target, a NIBT at 100% of budget is needed. To fund the maximum of the incentive pool, NIBT of 110% of budget must be achieved. The following table outlines the funding mechanism:

Offsetting [Abstract]

Balance Sheet Offsetting

DERIVATIVES AND HEDGING

The Company uses derivative financial instruments for risk management purposes (primarily interest rate risk) and not for trading or speculative purposes. The Company controls the credit risk associated with these derivative financial instruments through collateral, credit approvals and monitoring procedures.

Derivative financial instruments are carried at fair value on the consolidated statements of condition. The accounting for changes in the fair value of a derivative instrument is dependent upon whether or not it has been designated as a hedge for accounting purposes and, if so, the type of hedge it has been designated as. The changes in fair value of the Company's derivative instruments not designated as hedges are accounted for within the consolidated statements of income.

Quarterly, in conjunction with financial reporting, each cash flow hedge is assessed for ineffectiveness. To the extent ineffectiveness is identified, this amount is recorded within the consolidated statements of income. The gain or loss on the effective portion of the cash flow hedge is reclassified from AOCI into interest within the consolidated statements of income in the period the hedged transaction affects earnings.

Derivatives Not Designated as Hedges

Customer Loan Swaps

The Company will enter into interest rate swaps with its commercial customers to provide them with a means to lock into a long-term fixed rate, while simultaneously entering into an arrangement with a counterparty to swap the fixed rate to a variable rate to manage interest rate exposure effectively. As the interest rate swap agreements have substantially equivalent and offsetting terms, they do not materially change the Company's interest rate risk or present any material exposure to its consolidated statements of income. Customer loan swaps are presented on a gross basis within other assets and accrued interest and other liabilities on the consolidated statements of condition.

The following table presents the total positions, notional and fair value of the Company's customer loans swaps with each party for the dates indicated:

		December 31,
		2019						2018
(In thousands, except number of positions)	Presentation on Consolidated Statements of Condition	Number of Positions	Notional Amount		Fair Value			Number of Positions	Notional Amount		Fair Value
Receive fixed, pay variable	Accrued interest and other liabilities	10	$	45,243	$	(514	)	57	$	297,624	$	(7,841	)
Receive fixed, pay variable	Other assets	75	366,351		17,756			25	118,891		3,467
Pay fixed, receive variable	(Accrued interest and other liabilities)/other assets	85	411,594		(17,242		)	82	416,515		4,374
Total		170	$	823,188	$	—		164	$	833,030	$	—

The Company mitigates its customer counterparty credit risk exposure through its loan policy and underwriting process, which includes credit approval limits, monitoring procedures, and obtaining collateral, where appropriate. The Company mitigates its institutional counterparty credit risk exposure by limiting the institutions for which it will enter into interest swap arrangements through an approved listing by its Board of Directors.

The Company has entered into a master netting arrangement with its institutional counterparty and settles payments with the counterparty as necessary. The Company's arrangement with its institutional counterparty requires it to post cash or other assets as collateral for its contracts in a net liability position based on their aggregate fair value and the Company's credit rating. The Company may also receive cash collateral for contracts in a net asset position as requested. At December 31, 2019, the Company posted $18.4 million of cash as collateral and it was presented within other assets on the consolidated statements of condition. At December 31, 2018, the institutional counterparty posted $5.1 million of cash as collateral and it was presented within interest-bearing deposits in other banks as restricted cash with a matching liability within accrued interest and other liabilities on the consolidated statements of condition. Refer to Note 13 for further discussion of master netting arrangements and presentation within the Company's consolidated financial statements.

Fixed-Rate Mortgage Interest Rate Locks 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. The Company's pipeline of mortgage loans with fixed-rate interest rate lock commitments for which it intends to sell the loan upon origination was as follows for the dates indicated:

		December 31,
		2019					2018
(In thousands)	Presentation on Consolidated Statements of Condition	Notional Amount		Fair Value			Notional Amount		Fair Value
Fixed-rate mortgage interest rate locks	Other assets	$	27,087	$	480		$	8,239	$	95
Fixed-rate mortgage interest rate locks	Accrued interest and other liabilities	2,519		(18		)	3,838		(28		)
Total		$	29,606	$	462		$	12,077	$	67

For the year ended December 31, 2019, 2018 and 2017, the net unrealized gain (loss) from the change in fair value on the Company's fixed-rate mortgage rate locks reported within mortgage banking income, net, on the consolidated statements of income was $395,000, ($218,000), and $98,000, respectively.

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 has been 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.

The Company's forward delivery commitments on loans held for sale for the dates indicated were as follows:

		December 31,
		2019					2018
(In thousands)	Presentation on Consolidated Statements of Condition	Notional Amount		Fair Value			Notional Amount		Fair Value
Forward delivery commitments ("best effort")	Other assets	$	10,846	$	312		$	2,593	$	32
Forward delivery commitments ("best effort")	Accrued interest and other liabilities	1,069		(15		)	1,722		(17		)
Total		$	11,915	$	297		$	4,315	$	15

For the year ended December 31, 2019, 2018 and 2017, the net unrealized gain (loss) from the change in fair value on the Company's forward delivery commitments reported within mortgage banking income, net on the consolidated statements of income were $282,000, ($127,000), and ($136,000), respectively.

Derivatives Designated as Hedges

Interest Rate Swap on Loans

On June 12, 2019, the Company entered into a $100.0 million interest rate swap contract with a counterparty to manage interest rate risk associated with its variable-rate loans. The Company has entered into a master netting arrangement with its institutional counterparty and settles payments monthly on a net basis. The arrangement with the institutional counterparty requires it to post collateral for its interest rate swap on loans when it is in a net liability position based on its fair value. If the interest rate swap is in a net asset position based on its fair value, the institutional counterparty will post collateral to the Company as requested. At December 31, 2019, the institutional counterparty posted $560,000 of cash as collateral, which was presented within interest-bearing deposits in other banks as restricted cash with a matching liability within accrued interest and other liabilities on the consolidated statements of condition. Refer to Note 13 for further discussion of master netting arrangements and presentation within the Company's consolidated financial statements.

The details of the interest rate swap for the date indicated were as follows:

(Dollars in thousands)					December 31, 2019
Trade Date	Maturity Date	Variable Index Paid	Fixed Rate Received	Presentation on Consolidated Statements of Condition	Notional Amount		Fair Value
6/12/2019	6/10/2024	1-Month USD LIBOR	1.693%	Other assets	$	100,000	$	483

For the year ended December 31, 2019, the Company did not record any ineffectiveness within the consolidated statements of income.

Net payments paid to the institutional counterparty for the year ended December 31, 2019 were $214,000, and were classified as cash flows from operating activities in the Company's consolidated statements of cash flow.

Junior Subordinated Debt Interest Rate Swaps

The Company entered into five interest rate swap agreements with an institutional counterparty to manage interest rate risk associated with the Company's variable rate borrowings. The Company has entered into a master netting arrangement with its institutional counterparty and settles payments quarterly on a net basis. The interest rate swap arrangements contain provisions that require the Company to post cash or other assets as collateral with the counterparty for contracts that are in a net liability position based on their aggregate fair value and the Company’s credit rating. If the interest rate swaps are in a net asset position based on their aggregate fair value, the institutional counterparty will post collateral to the Company as requested. At December 31, 2019 and 2018, the Company posted $8.8 million and $5.8 million, respectively, of cash as collateral to the institutional counterparty, which is presented within other assets on the consolidated statements of condition. Refer to Note 13 for further discussion of master netting arrangements and presentation within the Company's consolidated financial statements.

The Company expects approximately $833,000 (pre-tax) to be reclassified to interest expense from OCI, related to the Company’s cash flow hedges, in the next 12 months. This reclassification is due to anticipated payments that will be made and/or received on the swaps based upon the forward curve as of December 31, 2019.

BALANCE SHEET OFFSETTING

The Company does not offset the carrying value for derivative instruments or repurchase agreements on the consolidated statements of condition. The Company does net the amount recognized for the right to reclaim cash collateral against the obligation to return cash collateral arising from instruments executed with the same counterparty under a master netting arrangement. Collateral legally required to be pledged or received is monitored and adjusted as necessary. Refer to Note 10 for further discussion of repurchase agreements and Note 12 for further discussion of derivative instruments.

Stock-Based Compensation Plans

STOCK-BASED COMPENSATION PLANS

Stock-Based Compensation

On April 29, 2003 and May 1, 2012, the shareholders of the Company approved the 2003 Plan and 2012 Plan, respectively. The maximum number of shares of stock reserved and available for issuance under each the 2003 Plan and 2012 Plan is 1.2 million shares. As shares or units are vested or options are exercised, new shares are issued out of either the 2003 or 2012 Plan. Awards may be granted in the form of incentive stock options, non-qualified stock options, stock appreciation rights, restricted stock, restricted stock units, unrestricted stock, performance shares and dividend equivalent rights, or any combination of the preceding, and the exercise price will not be less than 100% of the fair market value on the date of grant in the case of incentive stock options, or 85% of the fair market value on the date of grant in the case of non-qualified stock options. No stock option is exercisable more than ten years after the date the stock option was granted. The exercise price of all options granted equaled the market price of the Company's stock on the date of grant, except for certain non-qualified stock options that were issued in conjunction with an acquisition.

The amount of cash used to settle stock-based compensation transactions for the year ended December 31, 2019, 2018 and 2017 was $455,000, $848,000 and $902,000, respectively.

Stock Option Awards

Stock options granted under the 2003 Plan and the 2012 Plan include both incentive stock options and non-qualified stock options. Incentive stock options and non-qualified stock options granted vest pro-rata over a five year period, or earlier if an employee retires and has met the retirement eligibility requirements of the plan, and have a contractual life of ten years.

On the date of each grant, the fair value of each award is derived using the Black-Scholes option pricing model based on assumptions made by the Company as follows:

• Dividend yield is based on the dividend rate of the Company’s stock at the date of grant.

• Risk-free interest rate is based on the U.S. Treasury bond rate with a term equaling the expected life of the granted options.

• Expected volatility is based on the historical volatility of the Company’s stock price calculated over the expected life of the option.

• Expected life represents the period of time that granted options are expected to be outstanding based on historical trends.

For the year ended December 31, 2019, 2018 and 2017, the Company issued stock options with a grant-date fair value of $0, $8,000 and $0, respectively. The following table presents the option pricing assumptions and the estimated fair value of the options using these assumptions for grants made for the year ended:

	December 31,
	2019	2018			2017
Weighted-average dividend yield	N/A	2.36		%	N/A
Weighted-average risk-free interest rate	N/A	2.38		%	N/A
Weighted-average expected volatility	N/A	22.80		%	N/A
Weighted-average expected life (in years)	N/A	5.3			N/A
Weighted-average fair value of options granted	N/A	$	7.78		N/A

Compensation expense is recognized on a straight-line basis over the vesting period. For the year ended December 31, 2019, 2018 and 2017, the compensation expense recognized was $7,000, $10,000 and $20,000, respectively. The Company does not receive any tax benefit on its issuance of incentive stock options, unless upon exercise a disqualifying disposition is made. The total tax benefit to the Company upon exercise of incentive stock options for the year ended December 31, 2019, 2018 and 2017 was $8,000, $50,000, and $21,000, respectively. Additionally, for the year ended December 31, 2019, 2018 and 2017, the Company received a tax benefit upon the exercise of non-qualified stock options, of $1,000, $0 and $7,000, respectively.

LTIP

The LTIP is intended to attract and retain executives who will contribute to the Company’s future success. The long-term performance period is a period of three consecutive years beginning on January 1 of the first year and ending on December 31 of the third year. Awards granted are 50% weighted on the attainment of certain performance targets approved by the Board of Directors and 50% weighted on meeting the requisite service period.

DCRP

The DCRP is an unfunded deferred compensation plan for the benefit of certain Company executives. Annually, participants will receive a credit to an account administered by the Company of 10% of each participant’s annual base salary and bonus for the prior performance period. Annual credits to a participant’s account will be denominated in deferred stock awards (the right to receive a share of common stock of the Company upon the satisfaction of certain restrictions) based on the fair market value of the common stock of the Company on the date of grant. For all active participants vesting occurs ratably from the date of participation until the participant reaches the age of 65, at which time the participant is 100% vested. In 2018, the DCRP was amended providing the ability to tailor vesting terms for new participants.

For the year ended December 31, 2019, 2018 and 2017, the Company issued DCRP awards with a grant-date fair value of $153,000, $155,000 and $118,000, respectively. The grant-date fair value is calculated utilizing the Company's closing market share price as of the date the awards are granted.

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

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.

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.

Equity Securities: The fair value of equity securities in bank stock is determined using market prices based on recent trading activity and dealer quotes. These equity securities are traded on inactive markets and are 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 by the Company and its counterparties. As of December 31, 2019 and 2018, the Company has assessed the significance of the impact of the credit valuation adjustments on the overall valuation of its derivative positions and has determined that the credit valuation adjustments are not significant to the overall valuation of its derivatives due to collateral postings.

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:

The Company did not have any transfers between Level 1 and Level 2 of the fair value hierarchy for the year ended December 31, 2019. 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. 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.

Collateral-Dependent Impaired Loans:  Loans for which it is probable that payment of interest and principal will not be made in accordance with the contractual terms of the loan agreement are considered impaired. The Company's policy is to individually evaluate for impairment loans with a principal balance of $500,000 or more, that are classified as substandard or doubtful and are on non-accrual status. Once the population of loans is identified for individual impairment assessment, the Company measures these loans for impairment by comparing net realizable value, which is the fair value of the collateral, less estimated costs to sell, to the carrying value of the loan. If the net realizable value of the loan is less than the carrying value of the loan, then a loss is recognized as part of the ALL to adjust the loan's carrying value to net realizable value. Accordingly, certain collateral-dependent impaired loans are subject to measurement at fair value on a non-recurring basis. Management has estimated 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. At December 31, 2019 and 2018, the Company's mortgage servicing assets were not carried at fair value.

Non-Financial Instruments Recorded at Fair Value on a Non-recurring Basis

The Company has no non-financial assets or non-financial liabilities measured at fair value on a recurring basis. Non-financial assets measured at fair value on a non-recurring basis consist of OREO, goodwill and core deposit intangible assets.

OREO:OREO properties acquired through foreclosure or deed in lieu of foreclosure are recorded at net realizable value, which is the fair value of the real estate, less estimated costs to sell. Any write-down of the recorded investment in the related loan is charged to the ALL 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 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.

Goodwill and Core Deposit Intangible Assets: Goodwill represents the excess cost of an acquisition over the fair value of the net assets acquired. The fair value of goodwill is estimated by utilizing several standard valuation techniques, including discounted cash flow analyses, bank merger multiples, and/or an estimation of the impact of business conditions and investor activities on the long-term value of the goodwill. Should an impairment occur, the associated goodwill is written-down to fair value and the impairment charge is recorded within non-interest expense in the consolidated statements of income. The Company conducts an annual impairment test of goodwill in the fourth quarter each year, or more frequently as necessary. There have been no indications or triggering events for the year ended December 31, 2019 or 2018 for which management believed that it was more-likely-than-not that goodwill is impaired.

The Company's core deposit intangible assets represent the estimated value of acquired customer relationships and are 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. There were no indications or triggering events for the year ended December 31, 2019 or 2018 that indicated the carrying amount may not be recoverable.

The carrying value of residential real estate and commercial loans pledged as collateral was $1.4 billion and $1.1 billion at December 31, 2019 and 2018. The carrying value of investment securities pledged as collateral at the FHLBB was $150,000 and $172,000 at December 31, 2019 and 2018, respectively.

Subordinated Debentures

The Company issued $15.0 million of subordinated debt on October 8, 2015, which qualifies as Tier 2 regulatory capital. The interest rate on the subordinated debt is 5.50% per annum, fixed for the ten-year term and payable semi-annually on April 15 and October 15 each year. The Company can redeem the subordinated debt at par starting on October 15, 2020 plus accrued and unpaid interest, or earlier if (i) they no longer qualify as Tier 2 capital for regulatory capital purposes; (ii) a change in law that prevents the Company from deducting interest payable for U.S. federal income tax purposes, or (iii) the Company is required to register as an investment company pursuant to the Investment Company Act of 1940. The subordinated debt is scheduled to mature on October 15, 2025.

The Company incurred certain costs associated with the issuance of $15.0 million of subordinated debt. The Company capitalized these costs and they have been presented within subordinated debentures on the consolidated statements of condition. At December 31, 2019 and 2018, net debt issuance costs were $251,000 and $366,000, respectively. Debt issuance costs amortize over the expected life of the related debt. For the year ended December 31, 2019 and 2018 the amortization expense for debt issuance costs were $115,000 and $54,000, respectively, and were recognized as an increase to interest expense within the consolidated statements of income.

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. At December 31, 2019 and 2018, the interest rate on the trust preferred securities was 3.36% and 4.20%, 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 the average three-month LIBOR plus 1.42%. At December 31, 2019 and 2018, the interest rate on the trust preferred securities was 3.41% and 3.86%, 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, 2019, $43.0 million of the trust preferred securities were included in the Company’s total Tier 1 capital and amounted to 10.3% of Tier 1 capital of the Company.

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 $3.3 million, $3.4 million, and $3.4 million for the year ended December 31, 2019, 2018 and 2017, 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.

• The Bank had an available line of credit with the FHLBB of $9.9 million at December 31, 2019 and 2018. 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.

Diluted EPS	$	3.69		$	3.39		$	1.82

(1) Represents dividends paid and undistributed earnings allocated to nonvested stock-based awards that contain non-forfeitable rights to dividends.

(2) Represents the effect of the assumed exercise of stock options, vesting of restricted shares and restricted stock units, and issuance of LTIP awards that have met the performance criteria, utilizing the treasury stock method.

For the year ended December 31, 2019, 2018 and 2017 there were no anti-dilutive stock based awards that have been excluded from the computation of potential common shares for purposes of calculating diluted EPS, because the average market price of the Company's common stock is greater than the exercise prices.

Nonvested 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 nonvested 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 nonvested 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.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivatives and Hedging

DERIVATIVES AND HEDGING

The Company uses derivative financial instruments for risk management purposes (primarily interest rate risk) and not for trading or speculative purposes. The Company controls the credit risk associated with these derivative financial instruments through collateral, credit approvals and monitoring procedures.

Derivative financial instruments are carried at fair value on the consolidated statements of condition. The accounting for changes in the fair value of a derivative instrument is dependent upon whether or not it has been designated as a hedge for accounting purposes and, if so, the type of hedge it has been designated as. The changes in fair value of the Company's derivative instruments not designated as hedges are accounted for within the consolidated statements of income.

Quarterly, in conjunction with financial reporting, each cash flow hedge is assessed for ineffectiveness. To the extent ineffectiveness is identified, this amount is recorded within the consolidated statements of income. The gain or loss on the effective portion of the cash flow hedge is reclassified from AOCI into interest within the consolidated statements of income in the period the hedged transaction affects earnings.

Derivatives Not Designated as Hedges

Customer Loan Swaps

The Company will enter into interest rate swaps with its commercial customers to provide them with a means to lock into a long-term fixed rate, while simultaneously entering into an arrangement with a counterparty to swap the fixed rate to a variable rate to manage interest rate exposure effectively. As the interest rate swap agreements have substantially equivalent and offsetting terms, they do not materially change the Company's interest rate risk or present any material exposure to its consolidated statements of income. Customer loan swaps are presented on a gross basis within other assets and accrued interest and other liabilities on the consolidated statements of condition.

The following table presents the total positions, notional and fair value of the Company's customer loans swaps with each party for the dates indicated:

		December 31,
		2019						2018
(In thousands, except number of positions)	Presentation on Consolidated Statements of Condition	Number of Positions	Notional Amount		Fair Value			Number of Positions	Notional Amount		Fair Value

The Company mitigates its customer counterparty credit risk exposure through its loan policy and underwriting process, which includes credit approval limits, monitoring procedures, and obtaining collateral, where appropriate. The Company mitigates its institutional counterparty credit risk exposure by limiting the institutions for which it will enter into interest swap arrangements through an approved listing by its Board of Directors.

The Company has entered into a master netting arrangement with its institutional counterparty and settles payments with the counterparty as necessary. The Company's arrangement with its institutional counterparty requires it to post cash or other assets as collateral for its contracts in a net liability position based on their aggregate fair value and the Company's credit rating. The Company may also receive cash collateral for contracts in a net asset position as requested. At December 31, 2019, the Company posted $18.4 million of cash as collateral and it was presented within other assets on the consolidated statements of condition. At December 31, 2018, the institutional counterparty posted $5.1 million of cash as collateral and it was presented within interest-bearing deposits in other banks as restricted cash with a matching liability within accrued interest and other liabilities on the consolidated statements of condition. Refer to Note 13 for further discussion of master netting arrangements and presentation within the Company's consolidated financial statements.

Fixed-Rate Mortgage Interest Rate Locks 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. The Company's pipeline of mortgage loans with fixed-rate interest rate lock commitments for which it intends to sell the loan upon origination was as follows for the dates indicated:

		December 31,
		2019					2018
(In thousands)	Presentation on Consolidated Statements of Condition	Notional Amount		Fair Value			Notional Amount		Fair Value
Fixed-rate mortgage interest rate locks	Other assets	$	27,087	$	480		$	8,239	$	95
Fixed-rate mortgage interest rate locks	Accrued interest and other liabilities	2,519		(18		)	3,838		(28		)
Total		$	29,606	$	462		$	12,077	$	67

For the year ended December 31, 2019, 2018 and 2017, the net unrealized gain (loss) from the change in fair value on the Company's fixed-rate mortgage rate locks reported within mortgage banking income, net, on the consolidated statements of income was $395,000, ($218,000), and $98,000, respectively.

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 has been 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.

The Company's forward delivery commitments on loans held for sale for the dates indicated were as follows:

		December 31,
		2019					2018
(In thousands)	Presentation on Consolidated Statements of Condition	Notional Amount		Fair Value			Notional Amount		Fair Value
Forward delivery commitments ("best effort")	Other assets	$	10,846	$	312		$	2,593	$	32

Total		$	11,915	$	297		$	4,315	$	15

For the year ended December 31, 2019, 2018 and 2017, the net unrealized gain (loss) from the change in fair value on the Company's forward delivery commitments reported within mortgage banking income, net on the consolidated statements of income were $282,000, ($127,000), and ($136,000), respectively.

Derivatives Designated as Hedges

Interest Rate Swap on Loans

On June 12, 2019, the Company entered into a $100.0 million interest rate swap contract with a counterparty to manage interest rate risk associated with its variable-rate loans. The Company has entered into a master netting arrangement with its institutional counterparty and settles payments monthly on a net basis. The arrangement with the institutional counterparty requires it to post collateral for its interest rate swap on loans when it is in a net liability position based on its fair value. If the interest rate swap is in a net asset position based on its fair value, the institutional counterparty will post collateral to the Company as requested. At December 31, 2019, the institutional counterparty posted $560,000 of cash as collateral, which was presented within interest-bearing deposits in other banks as restricted cash with a matching liability within accrued interest and other liabilities on the consolidated statements of condition. Refer to Note 13 for further discussion of master netting arrangements and presentation within the Company's consolidated financial statements.

The details of the interest rate swap for the date indicated were as follows:

(Dollars in thousands)					December 31, 2019
Trade Date	Maturity Date	Variable Index Paid	Fixed Rate Received	Presentation on Consolidated Statements of Condition	Notional Amount		Fair Value

For the year ended December 31, 2019, the Company did not record any ineffectiveness within the consolidated statements of income.

Net payments paid to the institutional counterparty for the year ended December 31, 2019 were $214,000, and were classified as cash flows from operating activities in the Company's consolidated statements of cash flow.

Junior Subordinated Debt Interest Rate Swaps

The Company entered into five interest rate swap agreements with an institutional counterparty to manage interest rate risk associated with the Company's variable rate borrowings. The Company has entered into a master netting arrangement with its institutional counterparty and settles payments quarterly on a net basis. The interest rate swap arrangements contain provisions that require the Company to post cash or other assets as collateral with the counterparty for contracts that are in a net liability position based on their aggregate fair value and the Company’s credit rating. If the interest rate swaps are in a net asset position based on their aggregate fair value, the institutional counterparty will post collateral to the Company as requested.

BALANCE SHEET OFFSETTING

The Company does not offset the carrying value for derivative instruments or repurchase agreements on the consolidated statements of condition. The Company does net the amount recognized for the right to reclaim cash collateral against the obligation to return cash collateral arising from instruments executed with the same counterparty under a master netting arrangement. Collateral legally required to be pledged or received is monitored and adjusted as necessary. Refer to Note 10 for further discussion of repurchase agreements and Note 12 for further discussion of derivative instruments.

Revenue from Contracts with Customer

Revenue from Contract with Customer [Abstract]

Revenue from Contracts with Customer

REVENUE FROM CONTRACTS WITH CUSTOMERS

On January 1, 2018, the Company adopted ASC 606, the new revenue recognition standard,using the modified retrospective transition method.

A portion of the Company's non-interest income is derived from contracts with customers, and as such, the revenue recognized depicts the transfer of promised goods or services to its customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The Company considers the terms of the contract and all relevant facts and circumstances when applying this guidance.

The Company has disaggregated its revenue from contracts with customers into categories based on the nature of the revenue. The categorization of revenues from contracts with 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 December 31,
(In thousands)	Income Statement Line Item	2019		2018
Debit card interchange income	Debit card income	$	9,701	$	9,067
Services charges on deposit accounts	Service charges on deposit accounts	8,393		8,253
Fiduciary services income	Income from fiduciary services	5,901		5,376
Investment program income	Brokerage and insurance commissions	2,625		2,615
Other non-interest income	Other income	1,710		1,508
Total non-interest income within the scope of ASC 606		28,330		26,819
Total non-interest income not in scope of ASC 606		13,783		11,357
Total non-interest income		$	42,113	$	38,176

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 year ended December 31, 2019 and 2018, cash rewards totaled $554,000 and $438,000, respectively.

• Service charges on deposit accounts:Deposit-related fees, include, but are not limited to, overdraft income, service charge income, and other fees generated by the depositor relationship with the Company. For each depositor relationship, an agreement and related disclosures outline the terms of the contract between the depositor and the Bank, including the assessment of fees and fee structure for its various products. The contract 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.

• Fiduciary services income:The Company, through its wealth management and trust services department, doing business as Camden National Wealth Management, earns fees for its investment management and related services for its clients. Fees earned for its services are largely dependent on assets under management as of the last day of the month and do not contain performance clauses. Should the applicable services contract be terminated by either party, fees for services are earned up to the effective date of contract termination. As such, fiduciary services income is earned and recognized daily.

• Investment program income:Under an investment program offered by the Company, doing business as Camden Financial Consultant (“Program”), its clients are provided access to brokerage, advisory and insurance products offered through an unaffiliated third party. Certain Company employees are registered securities representatives and/or registered investment advisor representatives of the third party, operating in such capacity under Camden Financial Consultants to provide clients with brokerage, investment advisory and insurance related services. The Company receives a portion of the commissions and fees received by the unaffiliated third party brokerage firm from the sale of investment products and investment advisory services, in accordance with the terms of the contract between the two parties.

The revenues earned by the Company are net of administrative expenses and the portion retained by the unaffiliated third party brokerage firm. The Company does not have control of the specified services provided to its clients by the unaffiliated third party brokerage firm under the Program. Revenues earned from Program-related services are presented on the consolidated statements of income on a net basis.

Net unrealized gains on AFS investments reported within in AOCI at December 31, 2019, were $3.3 million, net of a deferred tax liability of $890,000. Net unrealized losses on AFS investments reported within AOCI at December 31, 2018, were $17.8 million, net of a deferred tax benefit of $4.9 million, respectively.

Impaired AFS and HTM Investments

Quarterly, management reviews the Company’s AFS and HTM investments to determine the cause, magnitude and duration of declines in the fair value of each security. Thorough evaluations of the causes of the unrealized losses are performed to determine whether the impairment is temporary or other-than-temporary in nature. Considerations such as the ability of the securities to meet cash flow requirements, levels of credit enhancements, risk of curtailment, and recoverability of invested amount over a reasonable period of time, and the length of time the security is in a loss position, for example, are applied in determining OTTI. Once a decline in value is determined to be other-than-temporary, the cost basis of the security is permanently reduced and a corresponding charge to earnings is recognized.

The following table presents the estimated fair values and gross unrealized losses on AFS and HTM investments that were in a continuous loss position that was considered temporary, by length of time that an individual security in each category has been in a continuous loss position as of the dates indicated:

At December 31, 2019 and 2018, unrealized losses within the AFS and HTM investment portfolios were reflective of current interest rates in excess of the yield received on debt investments and were not indicative of an overall change in credit quality or other factors. At December 31, 2019 and 2018, gross unrealized losses on the Company's AFS and HTM investments were 1% and 3%, respectively, of their respective fair values.

At December 31, 2019, the Company had the intent and ability to retain its debt investments that were in an unrealized loss position at December 31, 2019, until the decline in value has recovered.

As such, for reporting periods beginning on or after January 1, 2019, leases are recognized, presented and disclosed in accordance with ASU 2016-02, while periods prior to the adoption date were not adjusted and are reported in accordance with ASC 840, Leases ("ASC 840"). Refer to Note 1 for further details.

The Company enters into noncancellable lease arrangements primarily for its office buildings and 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. Many of these lease arrangements provide the Company with the option to renew the lease arrangement after the initial lease term. These options are included in determining the lease term used to establish the right-of-use assets and lease liabilities, when it is reasonably certain the Company will exercise its renewal option. As most of the Company's leases do not have a readily determinable implicit rate, the incremental borrowing rate is primarily used to determine the discount rate for purposes of measuring the right-of-use assets and lease liabilities. 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 Company Director serves as the Chairman and Chief Executive Officer of the other company. The term of the lease is through 2022.

Repurchase Agreements

12 Months Ended

Dec. 31, 2019

Banking and Thrift [Abstract]

Repurchase Agreements

REPURCHASE AGREEMENTS

The Company can raise additional liquidity by entering into repurchase agreements at its discretion. In a security repurchase agreement transaction, the Company will generally sell a security, agreeing to repurchase either the same or 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 statement of income. The securities underlying the agreements are delivered to counterparties as security for the repurchase obligations. Since 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 tables 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)	2019		2018

Total	$	237,984	$	245,868

(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.

Certain customers held CDs totaling $1.0 million and $923,000 at December 31, 2019 and 2018, 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.

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 guidelines apply to the Company on a consolidated basis.

Under the current guidelines, 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, four quarter trailing net income, net of distributions and tax effects not reflected in net income).

The Company and Bank's risk-based capital ratios exceeded regulatory requirements, including the capital conservation buffer, at December 31, 2019 and 2018, and the Bank's capital ratios met the requirements for the Bank to be considered "well capitalized" under prompt correct action provisions for each period. There were no changes to the Company or Bank's capital ratios that occurred subsequent to December 31, 2019 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, 2019				Minimum Regulatory Capital Required for Capital Adequacy plus Capital Conservation Buffer		Minimum Regulatory Provision To Be "Well Capitalized" Under Prompt Corrective Action Provisions		December 31, 2018				Minimum Regulatory Capital Required For Capital Adequacy plus Capital Conservation Buffer		Minimum Regulatory Provision To Be "Well Capitalized" Under Prompt Corrective Action Provisions

In 2015, the Company issued $15.0 million of subordinated debentures, and in 2006 and 2008, it issued $43.0 million of junior subordinated debentures in connection with the issuance of trust preferred securities. Although the subordinated debentures and 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, subject to certain limits, each within its calculation of risk-based capital. At December 31, 2019 and 2018, $15.0 million of subordinated debentures were included as Tier 2 capital and were included in the calculation of the Company's total risk-based capital, and, at December 31, 2019 and 2018, $43.0 million of the junior subordinated debentures were included in Tier 1 and total risk-based capital for the Company. The Company's $15.0 million of subordinated debentures are subject to phase-out of 20% annually beginning on its six year anniversary, and 20% a year thereafter until it is fully phased out.

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 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 regulations prescribed by the OCC, without prior OCC approval, a bank subsidiary may not declare dividends in any year in excess of the bank’s (i) net income for the current year, (ii) plus its retained net income for the prior two years.

For the year ended December 31, 2019, 2018, and 2017, the Bank declared dividends for payment to the Company in the amount of $36.9 million, $28.1 million, and $16.8 million, respectively. For the year ended December 31, 2019, 2018 and 2017, the Company declared $18.9 million, $18.0 million and $14.6 million, respectively, in dividends payable to its shareholders.

Common Stock Repurchase

In September 2013, the Company's Board of Directors authorized the 2013 Repurchase Plan which allowed for the repurchase of up to 375,000 shares of the Company’s outstanding common stock. During the year ended December 31, 2018, the Company purchased the remaining 750 shares of its common stock and completed its repurchase of the total allotment of 375,000 shares at a weighted-average price of $26.57.

In January 2019, the Company's Board of Directors authorized the purchase of up to 775,000 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, 2018. For the year ended December 31, 2019, the Company purchased 488,052 shares of its common stock at a weighted-average price of $42.61. This program is now closed.

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. This program replaces the 2019 program and is open for 12 months.

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, Property A, Inc. and Property P, 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 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 ALL, 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.

Subsequent Events. The Company has evaluated events and transactions subsequent to December 31, 2019 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 is 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. The Company is required by the FRB to maintain cash reserves equal to a percentage of deposits. The Company maintains the reserve balances in cash on hand or at the FRB.

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.

For periods prior to January 1, 2018, the Company's investments in equity securities with a readily determinable fair value may have been classified as trading or AFS. The classification was determined at the time of purchase and reflected the Company's corporate goals and objectives. For such periods, equity securities with a readily determinable fair value classified as AFS were carried on the consolidated statements of condition at fair value. Subsequent changes to fair value were accounted for within AOCI, net of tax, on consolidated statements of condition. The Company did not have any equity securities with a readily determinable fair value classified as trading as of December 31, 2017.

Effective January 1, 2018, upon adoption of ASU No. 2016-01, Income Statement- Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Liabilities ("ASU 2016-01"), equity investments may no longer be designated and accounted for as AFS securities, with the change in fair value recognized within AOCI, net of tax. Instead, the change in fair value of equity investments with a readily determinable fair value are to be recognized within net income and carried at fair value on the balance sheet. Upon adoption of ASU 2016-01, a cumulative-effect adjustment of $198,000 was recorded 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. This provision of ASU 2016-01 was applied prospectively. For the year ended December 31, 2019 and 2018, the Company recorded the change in fair value for its equity securities with a readily determinable fair value within other income on the consolidated statements of income. Refer to Note 2 for further details.

Management conducts a quarterly review and evaluation of its debt investments designated as AFS or HTM and, prior to the adoption of ASU 2016-01, effective January 1, 2018, conducted a quarterly review of its equity investments designated as AFS 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 debt investments classified as AFS or HTM that it does not intend to sell and is not more-likely-than-not will be 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 is recognized in non-interest income on the consolidated statements of income; and (ii) other factors is recognized in AOCI, net of tax. For the Company's debt securities it intends to sell and/or more-likely-than-not will be required to sell before recovery of amortized cost, an OTTI is 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.

Prior to the adoption of ASU 2016-01, for the Company's equity investments with a readily determinable fair value classified as AFS, for which the Company determined that the decline in the fair value was other-than-temporary, the Company would recognize the impairment within non-interest income on the consolidated statements of income when identified. Upon adoption of ASU 2016-01, effective January 1, 2018, the change in fair value of the Company's equity investments with a readily determinable fair value are recorded within net income and are no longer assessed for OTTI.

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.

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.

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 the Company's 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 are reported at amortized cost, or fair value in the case of acquired loans, 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. For acquired loans, interest income is also 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.

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.

ALL. The ALL is established through provisions for loan losses charged to income. Losses on loans, including impaired loans, are charged to the ALL when all or a portion of a loan is deemed to be uncollectible. Recoveries of loans previously charged off are credited to the ALL when realized.

In determining the appropriate level of ALL, the Company uses a methodology to systematically measure the amount of estimated loan loss exposure inherent in the loan portfolio. The methodology includes 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 is determined based on loans that have a principal balance of $500,000 or more that are classified as substandard or doubtful and are on non-accrual status. Such loans are classified as impaired and an allowance is established when the discounted expected future cash flows (or collateral value or observable market price) of the impaired loan is lower than the recorded investment of that loan. Loans that do not meet the above criteria are separated into risk pools by portfolio segment and risk ratings. The Company then evaluates 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 applies 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 currently an explicit part of the Company's methodology, could impact the risk rating assigned to that loan.

The Company at least annually, and more frequently as deemed prudent by management, reassesses and revises 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.

Since the methodology is based upon historical experience and trends, as well as management’s judgment, factors may arise that result in different estimations. Significant factors that could give rise to changes in these estimates may include, but are not limited to, changes in economic conditions in the Company’s market areas, concentration of risk, declines in local property values, and regulatory guidance.

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 are 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. 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.

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. 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 (commonly referred to as "Step Zero") 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 (i.e. "Step 1"). 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. If the reporting unit's fair value exceeds its carrying value, then goodwill is not impaired and no further assessment is required. However, if the reporting unit's fair value is less than its carrying value, the Company would then be required to determine the fair value of tangible and identifiable intangible assets and liabilities for the reporting unit, to derive an implied fair value of goodwill (i.e. "Step 2"). If the reporting unit's implied fair value of goodwill exceeds its carrying value, then goodwill is not impaired. However, if the reporting unit's implied fair value of goodwill is less than its carrying value, an impairment charge is recorded to carry goodwill at its calculated implied fair value.

The Company completed its annual goodwill impairment testing for its reporting unit as of November 30, 2019 using the qualitative analysis and it was determined that it was not more-likely-than-not that its carrying value exceeded its fair value. As such, goodwill was not impaired as of November 30, 2019.

Goodwill was tested for impairment as of November 30, 2018 and 2017 and was not impaired.

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, 2019, 2018 or 2017, 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 ALL 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, 2019 and 2018, OREO properties were carried within other assets on the consolidated statements of condition at $94,000 and $130,000, 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.

Operating expenses, including legal and other direct expenses, and changes in the valuation allowance relating to foreclosed assets are included in other non-interest expense on the consolidated statements of income.

Mortgage Banking. Residential real estate mortgages are originated by the Company both for its portfolio and 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 non-interest income 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 loan servicing fee 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, 2019 and 2018, 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. ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) ("ASC 606") was adopted by the Company on January 1, 2018. Refer to Note 16 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 Related Financial Instruments. 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. Refer to Note 11 for further details.

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 in 2019

ASU No. 2016-02, Leases (Topic 842) ("ASU 2016-02"): In February 2016, the FASB issued ASU 2016-02 to increase transparency and comparability among organizations by recognizing lease assets and liabilities (including operating leases) on the balance sheet and disclosing key information about leasing arrangements. Current lease accounting does not require the inclusion of operating leases in the balance sheet.

Effective January 1, 2019, the Company adopted ASU 2016-02, using the following practical expedients for transitional relief provided for within the subsequent issuance of ASU No. 2018-11, Leases (Topic 842): Targeted Improvements ("ASU 2018-11"):

• An entity need not reassess whether any expired or existing contract is or contains a lease.

• An entity need not reassess the lease classification for any expired or existing leases.

• An entity need not reassess initial direct costs for any existing leases.

• An entity may elect to apply hindsight to leases that existed during the period from the beginning of the earliest period presented in the financial statements until the effective date.

• A modified retrospective transition method, which allows companies to apply ASU 2016-02 at the date of adoption and recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption.

In conjunction with the adoption of Topic 842, the Company made the following accounting policy elections:

• For leases with a term of 12 months or less, a right-of-use asset or lease liability will not be recognized on the consolidated statements of condition.

• For non-real estate leased assets with individual undiscounted contractual cash flows of less than $500,000 over the reasonable certain term of the lease, a right-of -use asset or lease liability will not be recognized on the consolidated statements of condition as the lease is considered immaterial to the Company's financial statements.

The Company completed its assessment and implementation process for ASU 2016-02 and recorded operating and finance lease right-of-use assets of $12.1 million and lease liabilities of $12.3 million on the consolidated statements of condition within other assets and other liabilities, respectively, on January 1, 2019. Because the modified retrospective transition method was used, the Company did not revise prior period presentation on its consolidated statement of income. The adoption of the ASU did not have a material effect on the consolidated financial statements, which included a cumulative-effect adjustment of $254,000 to retained earnings on January 1, 2019. Refer to Note 6 for further details.

Recent Accounting Pronouncements to be Adopted in 2020

ASU No. 2016-13, Financial Instruments - Credit Losses(Topic 326): Measurement 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"), and ASU No. 2019-05, Financial Instruments - Credit Losses (Topic 326): Targeted Transition Relief ("ASU 2019-05").The FASB issued ASU 2016-13, commonly referred to as “CECL,” to require timelier recording of credit losses on loans and other financial instruments held by financial institutions and other organizations.

The Company will adopt ASU 2016-13, as amended, effective January 1, 2020, using a modified retrospective approach and will record a cumulative-effect adjustment to retained earnings. The measurement of expected credit losses under CECL is applicable to financial assets measured at amortized cost, including loan receivables and HTM debt securities. CECL also applies to certain off-balance sheet credit exposures, such as loan commitments, standby letters of credit, financial guarantees and other similar investments. In addition, ASU 2016-13 made changes to the accounting for AFS debt securities as a company will no longer immediately write-down a security for any impairment deemed to be a credit loss. Instead, a company will be required to present credit losses on AFS debt securities as an allowance on investments if it does not intend to sell the impaired security or it is not more-likely-than-not required to sell the impaired security before recovery of its amortized cost basis.

The Company assembled a cross-functional project team that met regularly to address the additional data requirements, to determine the approach for implementation and to identify new internal controls over enhanced accounting processes for estimating the allowance for credit losses (“ACL”). This included assessing the adequacy of existing loan and loss data, as well as assessing models for default and loss estimates. The Company is currently working to finalize its internal CECL policy and internal control framework.

The Company has substantially completed the development of its process for estimation of the allowance for loan losses and off-balance sheet exposures (i.e. ACL). To estimate the allowance for loan losses, the Company will primarily utilize a discounted cash flow model that contains additional assumptions to calculate credit losses over the estimated life of financial assets and will include the impact of forecasted economic conditions. To estimate the off-balance sheet credit exposures, which are primarily unfunded loan commitments, the Company will apply certain assumptions, including, but not limited to, a funding assumption and expected loss rate.

The Company has performed a parallel calculation as of December 31, 2019, comparing the allowance for loan losses calculated under current accounting guidance, commonly referred to as the “Incurred Model,” to the ACL calculated under CECL. Upon adoption of CECL in the first quarter of 2020, the Company anticipates that it will result in an immaterial impact to its consolidated financial statements, including the ACL and retained earnings, as well as the Company and Bank’s regulatory capital ratios.

ASU No. 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment ("ASU 2017-04"):The FASB issued ASU 2017-04 to reduce the cost and complexity of the goodwill impairment test. To simplify the subsequent measurement of goodwill, "Step 2" of the goodwill impairment test was eliminated. Instead, in accordance with ASU 2017-04, a Company will recognize an impairment of goodwill to the extent the carrying value of a reporting unit exceeds its fair value (i.e. "Step 1"). The Company will adopt ASU 2017-04 on January 1, 2020.

Effective January 1, 2020, prospectively the Company will no longer give consideration to "Step 2" when performing its goodwill impairment test. The Company does not expect the ASU to have a material impact on its consolidated financial statements.

Employee Benefit Plans

EMPLOYEE BENEFIT PLANS

401(k) and Profit Sharing Plan

The Company has a 401(k)/profit sharing plan and the majority of employees participate in the plan. Employees may contribute pre-tax contributions to the 401(k) plan up to the maximum amount allowed by federal tax laws. The Company makes matching contributions of up to 4% of an employee’s eligible compensation. The Company, at its discretion, may make profit sharing contributions to employees' 401(k) accounts in addition to its regular 401(k) plan matching contribution. For the year ended December 31, 2019, 2018 and 2017, these additional contributions totaled 3% of employee eligible compensation. For the year ended December 31, 2019, 2018 and 2017, expenses under the 401(k) and profit sharing plan totaled $2.4 million, $2.3 million, and $2.3 million, respectively.

SERP and Other Postretirement Benefit Plan

The Company sponsors unfunded, non-qualified SERPs for certain officers. These agreements are designed to make up the shortfall (when compared to a non-highly compensated employee) in replacing income at retirement due to IRS compensation and benefit limits under the 401(k) plan and Social Security. The SERP provides for a minimum 15-year guaranteed benefit for all vested participants.

The Company also provides medical and life insurance to certain eligible retired employees under the other postretirement benefit plan. This postretirement plan is a benefit only available to qualifying participants who were grandfathered.

The following table summarizes changes in the benefit obligation and plan assets for each postretirement benefit plan as of the dates indicated:

The accumulated benefit obligation for the SERP at December 31, 2019 and 2018 was $14.2 million and $12.1 million, respectively.

For the year ending December 31, 2020, the estimated actuarial loss on the SERP that will be amortized from AOCI into net periodic benefit cost is $623,000. All prior service costs have been fully amortized.

For the year ending December 31, 2020, the estimated actuarial loss and prior service credit on other postretirement benefits that will be amortized from AOCI into net periodic benefit cost is $78,000 and $24,000, respectively.

The components of net periodic benefit cost and other amounts recognized in OCI, before taxes, were as follows for the year ended December 31:

	SERP									Other Postretirement Benefits

The following assumptions were used in determining benefit obligations and net period benefit costs:

	SERP						Other Postretirement Benefits
	2019		2018		2017		2019		2018		2017
Weighted-average assumptions as of end of year:
Discount rate for benefit obligation	3.2	%	4.2	%	3.6	%	3.2	%	4.2	%	3.6	%
Discount rate for net periodic benefit cost	4.2	%	3.6	%	4.0	%	4.2	%	3.6	%	4.0	%
Rate of compensation increase for benefit obligation	3.0	%	3.0	%	5.0	%	N/A		N/A		N/A
Rate of compensation increase for net periodic benefit cost	3.0	%	3.0	%	5.0	%	N/A		N/A		N/A
Health care cost trend rate assumed for future years	N/A		N/A		N/A		4.5% - 7.0%		5.0% - 6.0%		5.0% - 6.0%

A 1.0% increase or decrease in the assumed health care cost trend rate would not materially increase or decrease the Company's accumulated postretirement benefit obligation and the related service and interest cost as of December 31, 2019.

For the year ended December 31, 2020, the expected contribution is $486,000 for the SERP and $268,000 for the other postretirement benefits plan. The expected benefit payments for the next ten years are presented in the following table:

(1) On December 22, 2017, the Tax Act was enacted, reducing the U.S. federal corporate income tax rate from 35.0% to 21.0%. The Company recognized the effect of the tax law changes in the period of enactment, which resulted in a reduction to net deferred tax assets and a corresponding charge to income tax expense of $14.3 million.

Temporary differences between the financial statements carrying amounts and the tax bases of assets and liabilities gave rise to the following deferred tax assets and liabilities as of the dates indicated:

	December 31,
	2019					2018
(In thousands)	Asset		Liability			Asset		Liability

Valuation allowance on deferred tax assets			—					—
Net deferred tax assets			$	16,823				$	23,053

At December 31, 2019 and 2018, the Company had $48.2 million and $52.1 million, respectively, in unused federal net operating losses that were acquired in 2015. 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, 2019 and 2018 determined that no valuation allowance was necessary.

As of December 31, 2019, the Company's federal and state income tax returns for the year ended December 31, 2018, 2017 and 2016 were open to audit by federal and state authorities.

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 for the dates indicated:

	December 31,
(In thousands)	2019		2018
Commitments to extend credit	$	734,649	$	654,575
Standby letters of credit	5,211		3,063
Total	$	739,860	$	657,638

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. Of the total commitments to extend credit, $274.6 million and $270.8 million were unconditionally cancellable by the Company at December 31, 2019 and 2018, respectively.

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.

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, we may be unable to estimate

reasonably possible losses with respect to every litigation matter we face.

As of December 31, 2019 and 2018, the Company did not have any material loss contingencies that were provided for and/or that are required to be disclosed.

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.

The HPFC loan portfolio is an acquired loan portfolio. It consists of niche commercial lending to the small business medical field, including dentists, optometrists and veterinarians across the U.S. The ability and willingness of borrowers to honor their repayment commitments is generally dependent on the success of the borrower's business. In 2016, the Company closed HPFC's operations and is no longer originating HPFC 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, 2019 and 2018, outstanding loans to certain officers, directors and their associated companies was less than 5% of the Company's shareholders' equity.

The ALL is management’s best estimate of the inherent risk of loss in the Company’s loan portfolio as of the consolidated statement of condition date. Management makes various assumptions and judgments about the collectability of the loan portfolio and provides an allowance for potential losses based on a number of factors including historical losses. If those assumptions are incorrect, the ALL may not be sufficient to cover losses and may cause an increase in the allowance in the future. Among the factors that could affect the Company’s ability to collect loans and require an increase to the allowance in the future are: (i) financial condition of borrowers; (ii) real estate market changes; (iii) state, regional, and national economic conditions; and (iv) a requirement by federal and state regulators to increase the provision for loan losses or recognize additional charge-offs.

The Company completed its annual ALL policy review in the fourth quarter of 2019, and no significant changes to its ALL methodology were made.

The Board of Directors monitors credit risk through the Directors' Loan Review Committee, which reviews large credit exposures, monitors external loan reviews, 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, concentration levels, and the ALL methodology. Credit Risk Administration and the Credit Risk Policy Committee oversee the Company's systems and procedures to monitor the credit quality of its loan portfolio, conduct a loan review program, maintain the integrity of the loan rating system, determine the adequacy of the ALL and support the oversight efforts of the Directors' Loan Review Committee and the Board of Directors. The Company's practice is to manage the portfolio proactively such that management can identify problem credits early, assess and 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.

For purposes of determining the ALL, the Company disaggregates its loans into portfolio segments, which include residential real estate, commercial real estate, commercial, home equity, consumer and HPFC. Each portfolio segment possesses unique risk characteristics that are considered when determining the appropriate level of allowance. These risk characteristics unique to each portfolio segment include the following:

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.

Commercial Real Estate. Commercial real estate loans consist of mortgage loans to finance investments in real property such as multi-family residential, commercial/retail, office, industrial, hotels, educational, health care 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. Loan-to-value ratios at origination are governed by established policy and regulatory guidelines. Commercial real estate loans are primarily paid by the cash flow generated from the real property, such as operating leases, rents, or other operating cash flows from the borrower.

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.

Home Equity. Home equity loans and lines are made to qualified individuals for legitimate purposes 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. Consumer loans may be secured or unsecured.

HPFC. Prior to the Company's closing of HPFC's operations in 2016, it provided commercial lending to dentists, optometrists and veterinarians, many of which were start-up companies. HPFC's loan portfolio consists of term loan obligations extended for the purpose of financing working capital and/or purchase of equipment. Collateral consists of pledges of business assets including, but not limited to, accounts receivable, inventory, and/or equipment. These loans are primarily paid by the operating cash flow of the borrower and the original terms ranged from seven to ten years.

(1) The provision (credit) for loan losses excludes any impact for the change in the reserve for unfunded commitments, which represents management's estimate of the amount required to reflect the probable inherent losses on outstanding letters of credit and unused lines of credit. The reserve for unfunded commitments was presented within accrued interest and other liabilities on the consolidated statements of condition. At December 31, 2019, 2018, and 2017, the reserve for unfunded commitments was $21,000, $22,000 and $20,000, respectively.

The following table reconciles the provision for loan losses to the provision for credit losses as presented on the consolidated statement of income for the periods indicated:

	For the Year Ended December 31,
(In thousands)	2019			2018		2017

Provision for credit losses	$	2,861		$	847	$	3,035

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 ensure that credit concentrations can be effectively identified, all commercial and commercial real estate loans are assigned Standard Industrial Classification codes, North American Industry Classification System codes, and state and county codes. Shifts in portfolio concentrations are monitored. As of December 31, 2019, the Company's total exposure to the lessors of nonresidential buildings' industry was 12% of total loans and 31% of total commercial real estate loans. There were no other industry concentrations exceeding 10% of the Company's total loan portfolio as of December 31, 2019.

 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, commercial real estate, residential real estate, and HPFC loans 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 ALL:

• 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.

Asset quality indicators are periodically reassessed to appropriately reflect 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.

The Company closely monitors the performance of its loan portfolio. A loan is placed on non-accrual status when the financial condition of the borrower is deteriorating, payment in full of both principal and interest is not expected as scheduled or principal or interest has been in default for 90 days or more. Exceptions may be made if the asset is secured by collateral sufficient to satisfy both the principal and accrued interest in full and collection is reasonably assured. When one loan to a borrower is placed on non-accrual status, all other loans to the borrower are re-evaluated to determine if they should also be placed on non-accrual status. All previously accrued and unpaid interest is reversed at this time. A loan will return to accrual status when collection of principal and interest is assured and the borrower has demonstrated timely payments of principal and interest for a reasonable period, generally at least six months. Unsecured loans, however, are not normally placed on non-accrual status because they are 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 a summary of non-accrual loans, which include TDRs, and loans past due over 90 days and accruing as of the following dates:

Interest income that would have been recognized if loans on non-accrual status had been current in accordance with their original terms for the year ended December 31, 2019, 2018, and 2017 is estimated to have been $420,000, $600,000, and $843,000, respectively.

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 ALL for the dates indicated:

	Number of Contracts		Recorded Investment				Specific Reserve

As of December 31, 2019, the Company did not have any other commitments to lend additional funds to borrowers with loans classified as TDRs.

For the year ended December 31, 2019 and 2017, no loans were modified as TDRs within the previous 12 months for which the borrower subsequently defaulted. For the year ended December 31, 2018, one home equity loan with a recorded investment of $299,000 at December 31, 2018 was modified as a TDR within the previous 12 months for which the borrower subsequently defaulted. At December 31, 2018, the Company carried a specific reserve on this redefaulted TDR of $162,000.

In-Process Foreclosure Proceedings

At December 31, 2019 and 2018, the Company had $1.3 million and $2.3 million, respectively, of consumer mortgage loans secured by residential real estate properties for which foreclosure proceedings were in process. The Company continues to work these consumer mortgage loans through the foreclosure process to resolution; however, the foreclosure process typically will take 18 to 24 months due to the state of Maine foreclosure laws.

MORTGAGE BANKING

Loans Sold

For the year ended December 31, 2019, 2018 and 2017, the Company sold $271.8 million, $205.9 million and $218.6 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 $6.4 million, $5.5 million, and $6.3 million, respectively.

Loans Held for Sale

At December 31, 2019 and 2018, the Company had identified and designated loans with an unpaid principal balance of $11.9 million and $4.3 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, 2019 and 2018, the unrealized (loss) gain recorded was ($61,000) and $89,000, 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 year ended December 31, 2019, 2018 and 2017 was the change in unrealized (losses) gains on loans held for sale of ($150,000), $52,000 and $326,000, 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 year ended December 31, 2019, 2018 and 2017, net unrealized gains (losses) from the change in fair value on its forward delivery commitments were $282,000, ($127,000), and ($136,000), respectively. Refer to Note 12 for further discussion of the Company's forward delivery commitments.

Servicing Assets

At December 31, 2019 and 2018, the Company's unpaid principal balances on its servicing assets were $227.8 million and $235.4 million, respectively.

For the year ended December 31, 2019, 2018 and 2017, the Company recorded servicing fee income for its servicing assets of $898,000, $949,000 and $1.0 million, respectively, and 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, 2019 and 2018 was $877,000 and $831,000, respectively. 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, 2019 and 2018, the prepayment assumption used within the valuation model was 14.4% and 11.5%, respectively, and the discount rate was 11.2% and 11.1%. The estimated effect of a 10% and 20% increase to the prepayment assumption at December 31, 2019 was a decrease of $65,000 and $126,000, respectively, while a 100 and 200 basis point increase to the discount rate assumption was a decrease of $47,000 and $90,000. 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:

Servicer and Sub-Servicer Net Worth and Liquidity Requirements

The Bank, as a servicer and sub-servicer of loans, must maintain certain net worth and liquidity requirements for certain secondary market investors, including HUD, FNMA and FHLMC.

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 but would not materially affect the Company's consolidated financial statements.

At December 31, 2019 and 2018, 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, 2019 and 2018.

Business and Summary of Significant Accounting Policies (Policies)

12 Months Ended

Dec. 31, 2019

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, Property A, Inc. and Property P, 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 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, including the ALL, 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.

Subsequent Events

Subsequent Events. The Company has evaluated events and transactions subsequent to December 31, 2019 for potential recognition or disclosure as required by GAAP.

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 is 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

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. The Company is required by the FRB to maintain cash reserves equal to a percentage of deposits. The Company maintains the reserve balances in cash on hand or at the FRB.

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.

For periods prior to January 1, 2018, the Company's investments in equity securities with a readily determinable fair value may have been classified as trading or AFS. The classification was determined at the time of purchase and reflected the Company's corporate goals and objectives. For such periods, equity securities with a readily determinable fair value classified as AFS were carried on the consolidated statements of condition at fair value. Subsequent changes to fair value were accounted for within AOCI, net of tax, on consolidated statements of condition. The Company did not have any equity securities with a readily determinable fair value classified as trading as of December 31, 2017.

Effective January 1, 2018, upon adoption of ASU No. 2016-01, Income Statement- Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Liabilities ("ASU 2016-01"), equity investments may no longer be designated and accounted for as AFS securities, with the change in fair value recognized within AOCI, net of tax. Instead, the change in fair value of equity investments with a readily determinable fair value are to be recognized within net income and carried at fair value on the balance sheet. Upon adoption of ASU 2016-01, a cumulative-effect adjustment of $198,000 was recorded 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. This provision of ASU 2016-01 was applied prospectively. For the year ended December 31, 2019 and 2018, the Company recorded the change in fair value for its equity securities with a readily determinable fair value within other income on the consolidated statements of income. Refer to Note 2 for further details.

Management conducts a quarterly review and evaluation of its debt investments designated as AFS or HTM and, prior to the adoption of ASU 2016-01, effective January 1, 2018, conducted a quarterly review of its equity investments designated as AFS 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 debt investments classified as AFS or HTM that it does not intend to sell and is not more-likely-than-not will be 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 is recognized in non-interest income on the consolidated statements of income; and (ii) other factors is recognized in AOCI, net of tax. For the Company's debt securities it intends to sell and/or more-likely-than-not will be required to sell before recovery of amortized cost, an OTTI is 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.

Prior to the adoption of ASU 2016-01, for the Company's equity investments with a readily determinable fair value classified as AFS, for which the Company determined that the decline in the fair value was other-than-temporary, the Company would recognize the impairment within non-interest income on the consolidated statements of income when identified. Upon adoption of ASU 2016-01, effective January 1, 2018, the change in fair value of the Company's equity investments with a readily determinable fair value are recorded within net income and are no longer assessed for OTTI.

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.

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.

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 the Company's 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

Originated Loans and Acquired Loans. Loans are reported at amortized cost, or fair value in the case of acquired loans, 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. For acquired loans, interest income is also 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.

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.

ALL

ALL. The ALL is established through provisions for loan losses charged to income. Losses on loans, including impaired loans, are charged to the ALL when all or a portion of a loan is deemed to be uncollectible. Recoveries of loans previously charged off are credited to the ALL when realized.

In determining the appropriate level of ALL, the Company uses a methodology to systematically measure the amount of estimated loan loss exposure inherent in the loan portfolio. The methodology includes 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 is determined based on loans that have a principal balance of $500,000 or more that are classified as substandard or doubtful and are on non-accrual status. Such loans are classified as impaired and an allowance is established when the discounted expected future cash flows (or collateral value or observable market price) of the impaired loan is lower than the recorded investment of that loan. Loans that do not meet the above criteria are separated into risk pools by portfolio segment and risk ratings. The Company then evaluates 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 applies 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 currently an explicit part of the Company's methodology, could impact the risk rating assigned to that loan.

The Company at least annually, and more frequently as deemed prudent by management, reassesses and revises 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.

Since the methodology is based upon historical experience and trends, as well as management’s judgment, factors may arise that result in different estimations. Significant factors that could give rise to changes in these estimates may include, but are not limited to, changes in economic conditions in the Company’s market areas, concentration of risk, declines in local property values, and regulatory guidance.

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 are 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. 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.

Goodwill and Core Deposit Intangible Assets

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. 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 (commonly referred to as "Step Zero") 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 (i.e. "Step 1"). 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. If the reporting unit's fair value exceeds its carrying value, then goodwill is not impaired and no further assessment is required. However, if the reporting unit's fair value is less than its carrying value, the Company would then be required to determine the fair value of tangible and identifiable intangible assets and liabilities for the reporting unit, to derive an implied fair value of goodwill (i.e. "Step 2"). If the reporting unit's implied fair value of goodwill exceeds its carrying value, then goodwill is not impaired. However, if the reporting unit's implied fair value of goodwill is less than its carrying value, an impairment charge is recorded to carry goodwill at its calculated implied fair value.

The Company completed its annual goodwill impairment testing for its reporting unit as of November 30, 2019 using the qualitative analysis and it was determined that it was not more-likely-than-not that its carrying value exceeded its fair value. As such, goodwill was not impaired as of November 30, 2019.

Goodwill was tested for impairment as of November 30, 2018 and 2017 and was not impaired.

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, 2019, 2018 or 2017, 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 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. 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. 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 ALL 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, 2019 and 2018, OREO properties were carried within other assets on the consolidated statements of condition at $94,000 and $130,000, 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.

Operating expenses, including legal and other direct expenses, and changes in the valuation allowance relating to foreclosed assets are included in other non-interest expense on the consolidated statements of income.

Mortgage Banking

Mortgage Banking. Residential real estate mortgages are originated by the Company both for its portfolio and 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 non-interest income 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 loan servicing fee 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 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. 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, 2019 and 2018, 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 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. 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

Revenue from Contracts with Customers. The Company receives a portion of its non-interest income from contracts with customers. ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) ("ASC 606") was adopted by the Company on January 1, 2018. Refer to Note 16 for further details.

Stock-Based Compensation

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 Related Financial Instruments

Off-Balance Sheet Credit Related Financial Instruments. 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. Refer to Note 11 for further details.

Derivative Financial Instruments Designated as Hedges

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

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 Adopted in 2019

ASU No. 2016-02, Leases (Topic 842) ("ASU 2016-02"): In February 2016, the FASB issued ASU 2016-02 to increase transparency and comparability among organizations by recognizing lease assets and liabilities (including operating leases) on the balance sheet and disclosing key information about leasing arrangements. Current lease accounting does not require the inclusion of operating leases in the balance sheet.

Effective January 1, 2019, the Company adopted ASU 2016-02, using the following practical expedients for transitional relief provided for within the subsequent issuance of ASU No. 2018-11, Leases (Topic 842): Targeted Improvements ("ASU 2018-11"):

• An entity need not reassess whether any expired or existing contract is or contains a lease.

• An entity need not reassess the lease classification for any expired or existing leases.

• An entity need not reassess initial direct costs for any existing leases.

• An entity may elect to apply hindsight to leases that existed during the period from the beginning of the earliest period presented in the financial statements until the effective date.

• A modified retrospective transition method, which allows companies to apply ASU 2016-02 at the date of adoption and recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption.

In conjunction with the adoption of Topic 842, the Company made the following accounting policy elections:

• For leases with a term of 12 months or less, a right-of-use asset or lease liability will not be recognized on the consolidated statements of condition.

• For non-real estate leased assets with individual undiscounted contractual cash flows of less than $500,000 over the reasonable certain term of the lease, a right-of -use asset or lease liability will not be recognized on the consolidated statements of condition as the lease is considered immaterial to the Company's financial statements.

The Company completed its assessment and implementation process for ASU 2016-02 and recorded operating and finance lease right-of-use assets of $12.1 million and lease liabilities of $12.3 million on the consolidated statements of condition within other assets and other liabilities, respectively, on January 1, 2019. Because the modified retrospective transition method was used, the Company did not revise prior period presentation on its consolidated statement of income. The adoption of the ASU did not have a material effect on the consolidated financial statements, which included a cumulative-effect adjustment of $254,000 to retained earnings on January 1, 2019. Refer to Note 6 for further details.

Recent Accounting Pronouncements to be Adopted in 2020

ASU No. 2016-13, Financial Instruments - Credit Losses(Topic 326): Measurement 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"), and ASU No. 2019-05, Financial Instruments - Credit Losses (Topic 326): Targeted Transition Relief ("ASU 2019-05").The FASB issued ASU 2016-13, commonly referred to as “CECL,” to require timelier recording of credit losses on loans and other financial instruments held by financial institutions and other organizations.

The Company will adopt ASU 2016-13, as amended, effective January 1, 2020, using a modified retrospective approach and will record a cumulative-effect adjustment to retained earnings. The measurement of expected credit losses under CECL is applicable to financial assets measured at amortized cost, including loan receivables and HTM debt securities. CECL also applies to certain off-balance sheet credit exposures, such as loan commitments, standby letters of credit, financial guarantees and other similar investments. In addition, ASU 2016-13 made changes to the accounting for AFS debt securities as a company will no longer immediately write-down a security for any impairment deemed to be a credit loss. Instead, a company will be required to present credit losses on AFS debt securities as an allowance on investments if it does not intend to sell the impaired security or it is not more-likely-than-not required to sell the impaired security before recovery of its amortized cost basis.

The Company assembled a cross-functional project team that met regularly to address the additional data requirements, to determine the approach for implementation and to identify new internal controls over enhanced accounting processes for estimating the allowance for credit losses (“ACL”). This included assessing the adequacy of existing loan and loss data, as well as assessing models for default and loss estimates. The Company is currently working to finalize its internal CECL policy and internal control framework.

The Company has substantially completed the development of its process for estimation of the allowance for loan losses and off-balance sheet exposures (i.e. ACL). To estimate the allowance for loan losses, the Company will primarily utilize a discounted cash flow model that contains additional assumptions to calculate credit losses over the estimated life of financial assets and will include the impact of forecasted economic conditions. To estimate the off-balance sheet credit exposures, which are primarily unfunded loan commitments, the Company will apply certain assumptions, including, but not limited to, a funding assumption and expected loss rate.

The Company has performed a parallel calculation as of December 31, 2019, comparing the allowance for loan losses calculated under current accounting guidance, commonly referred to as the “Incurred Model,” to the ACL calculated under CECL. Upon adoption of CECL in the first quarter of 2020, the Company anticipates that it will result in an immaterial impact to its consolidated financial statements, including the ACL and retained earnings, as well as the Company and Bank’s regulatory capital ratios.

ASU No. 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment ("ASU 2017-04"):The FASB issued ASU 2017-04 to reduce the cost and complexity of the goodwill impairment test. To simplify the subsequent measurement of goodwill, "Step 2" of the goodwill impairment test was eliminated. Instead, in accordance with ASU 2017-04, a Company will recognize an impairment of goodwill to the extent the carrying value of a reporting unit exceeds its fair value (i.e. "Step 1"). The Company will adopt ASU 2017-04 on January 1, 2020.

Effective January 1, 2020, prospectively the Company will no longer give consideration to "Step 2" when performing its goodwill impairment test. The Company does not expect the ASU to have a material impact on its consolidated financial statements.
