Shown below is a profile and geographical footprint of the Bank as of December 31, 2020:

The Bank serves affluent and growing markets in Maine, New Hampshire and Vermont with more than 37 thousand, 32 thousand and 16 thousand customers, respectively. Within these markets, tourism, agriculture and fishing industries remain strong and continue to drive economic activity. These core markets have also maintained their strength through diversification into various service industries.

Maine

The Bank operates 23 full-service branches principally located in the regions of downeast, midcoast and central Maine, which can generally be characterized as rural areas. The Bank also has a commercial loan office in Portland, Maine. In Maine, the Bank considers its primary market areas to be Hancock, Penobscot, Washington, Kennebec, Knox and Sagadahoc counties. The economies in these counties are based primarily on tourism, healthcare, fishing and lobstering, agriculture, state government, and small local businesses and are also supported by a large contingent of retirees.

New Hampshire

The Bank operates 20 full-service branches and 3 wealth management offices in New Hampshire located in the regions of Lake Sunapee, Upper Valley and Merrimack Valley. A new full-service branch was opened in Bedford, New Hampshire on January 4, 2021. There are several distinct markets within each of these regions. The towns or cities of Nashua, Manchester, and Concord are considered part of the Merrimack Valley. Nashua, New Hampshire is a regional commercial, entertainment and dining destination and with its border with Massachusetts, also enjoys a vibrant high-tech industry and a robust retail industry due in part to the state’s absence of a sales tax. The upper valley region of New Hampshire includes the towns of Lebanon and Hanover, which are home to Dartmouth-Hitchcock Medical Center and Dartmouth College, respectively. The Lake Sunapee market is a popular year-round recreation and resort area that includes both Lake Sunapee and Mount Sunapee and includes the towns of Claremont, New London, and Newport.

Vermont

The Bank operates 10 full-service branches in Vermont. The branches are primarily located in central Vermont within the counties of Rutland, Windsor and Orange.

Commercial Real Estate

Commercial real estate loans are secured primarily by multifamily dwellings, industrial/warehouse buildings, retail centers, office buildings and hospitality properties, primarily located in the Company’s market area in New England. The Company’s loans secured by commercial real estate are originated with either a fixed or an adjustable interest rate. Interest rates on adjustable rate loans are based on a variety of indices, generally determined through negotiations with borrowers. The Bank’s commercial real estate underwriting guidelines call for loan-to-value ratios not to exceed 80 percent of the appraised value of the underlying property securing the loan. Loans generally require monthly payments containing balloon payments with maturities of 10 years or less based on 25 year or less amortization schedules for commercial real estate and multifamily loans.

Commercial and Industrial Loans

Commercial and industrial loans are made to finance operations, provide working capital, finance the purchase of fixed assets, and business acquisitions. Additionally, commercial and industrial loans attract multifaceted relationships, which include deposit and treasury management services. A borrower’s cash flow from operations is generally the primary source of repayment. Accordingly, the Company’s loan policy provides specific guidelines regarding debt service coverage and other financial ratios. Commercial and industrial loans include lines of credit, commercial term loans and owner-occupied commercial real estate loans. Commercial lines of credit are extended to businesses generally to finance operations and working capital needs. Commercial term loans are typically made to finance the acquisition of fixed assets, refinance short-term debt originally used to purchase fixed assets or make business acquisitions. Commercial and industrial loans are extended based on the financial strength and integrity of the borrower and guarantor(s) and are generally collateralized by the borrower’s assets such as accounts receivable, inventory, equipment or real estate, typically with a term based on the collateral’s useful life of 1-10 years. The interest rates on these loans generally are adjustable and usually are indexed to The Wall Street Journal’s prime rate (Prime Rate) or London Interbank Offered Rate (LIBOR) and the spread will vary based on market conditions and perceived credit risk.

In order to mitigate the risk of loss, the Company generally requires collateral and personal guarantees to support commercial and industrial loans. The Company attempts to mitigate risk by limiting advance rates against eligible collateral to no more than 80%, though appropriate advance rates can vary depending on asset class.

The Company participates in the Small Business Administration’s (SBA) Paycheck Protection Program (PPP) initiated by the CARES Act of 2020. The program was designed to provide short-term relief to help small businesses sustain operations. Borrowers have the opportunity to have these loans forgiven upon acceptance of their documentation by the SBA. Upon forgiveness the SBA will reimburse the Company for any principal and accrued interest on the loan. The Company began offering PPP loans to customers in 2020 and is currently accepting loan applications for additional PPP loans under the Consolidated Appropriations Act of 2021.

Residential Real Estate

The Company offers fixed-rate and adjustable-rate residential mortgage loans to individuals with maturities of up to 30 years that are fully amortizing with monthly loan payments. Certain loans are originated for sale with rate lock commitments which are recorded as derivative financial instruments. Mortgages are generally underwritten according to U.S. government sponsored enterprise guidelines designated as “conforming loans”. The Company also originates jumbo loans above conforming loan amounts which generally are consistent with secondary market guidelines for these loans; however, these are typically held for investment. The Company does not offer a subprime mortgage lending program. Mortgage loans sold on the secondary market are sold on a servicing-retained basis.

Consumer Loans

The Company offers a variety of secured consumer loans, including second deed-of-trust home equity loans, home equity lines of credit ("HELOCs"), personal property and loans secured by deposits. The Company also offers a limited amount of unsecured loans. The Company originates consumer loans primarily in its market area. Consumer loans generally have shorter terms to maturity or variable interest rates, which reduce the Company’s exposure to changes in interest rates, and carry higher rates of interest than residential real estate loans. The Company believes that offering consumer loan products is critical to community banking by providing customer service at the holistic relationship level.

HELOCs have a 10 or 15 year draw period followed by a 20 year amortization and require either interest-only payments during the draw period or the payment of 1.0% or 1.5% of the outstanding loan balance per month (depending on the terms). Following receipt of payments, the available credit includes amounts repaid up to the credit limit. HELOCs with a 10 year draw period have a balloon payment due at the end of the draw period and then amortize for the remaining term. For loans with shorter-term draw periods, once the draw period has lapsed, generally the payment is fixed based on the loan balance and prevailing market interest rates at that time.

​

Problem Assets

The Bank prefers to work with borrowers to resolve problems rather than proceeding to foreclosure. For commercial loans, this may result in a period of forbearance or restructuring of the loan, which is normally done at current market terms and may not result in a “troubled” loan designation. For residential mortgage loans, the Bank generally follows the Consumer Financial Protection Bureau (“CFPB”) guidelines to attempt a restructuring that will enable owner-occupants to remain in their home. However, if these processes fail to result in a performing loan, the Bank generally will initiate foreclosure or other proceedings no later than the 120th day of a delinquency, as necessary, to minimize any potential loss. Management reports on delinquent loans and non-performing assets to the Board monthly. Loans are generally removed from accruing status when they reach 90 days delinquent, except for certain loans which are well secured and in the process of collection.

Loan collections are managed by a combination of the related business units and the Bank’s managed assets group, which focuses on larger, riskier collections and the recovery of purchased credit impaired loans.

Allowance for Loan Losses

The Bank’s loan portfolio is regularly reviewed by management to evaluate the adequacy of the allowance for loan losses. The allowance represents management’s estimate of inherent losses that are probable and estimable as of the date of the financial statements. The allowance includes a specific component for impaired loans (a “specific loan loss reserve”) and a general component for portfolios of all outstanding loans (a “general loan loss reserve”). At the time of acquisition, no allowance for loan losses is assigned to loans acquired in business combinations. These loans are carried at fair value, including the impact of expected losses, as of the acquisition date. The loan loss allowance is discussed further in Note 1 - Summary of Significant Accounting Policies of the Consolidated Financial Statements.

The following table presents year-end data for the approximate allocation of the allowance for loan losses by loan categories at the dates indicated. The table shows for each category the amount of the allowance allocated to that category as a percentage of the outstanding loans in that category. Management believes that the allowance can be allocated by category only on an approximate basis. The allocation of the allowance to each category is not indicative of future losses and does not restrict the use of any of the allowance to absorb losses in any category. Due to the impact of accounting standards for acquired loans, data in the accompanying tables may not be comparable between accounting periods.

INVESTMENT SECURITIES ACTIVITIES

The general objectives of the Company’s investment portfolio are to provide liquidity when loan demand is high, and to absorb excess funds when demand is low.

DERIVATIVE FINANCIAL INSTRUMENTS

The Company utilizes interest swap derivatives to minimize fluctuations in earnings and cash flows caused by interest rate volatility either in the form of interest rate swaps on wholesale funding designated as cash flow hedges or partial interest rate hedges on securities accounted for as fair value hedges. For further discussion on derivatives see Note 11 - Derivative Financial Instruments and Hedging Activities of the Consolidated Financial Statements.

​

The Company offers derivative products in the form of interest rate swaps and interest rate caps, to commercial loan customers to facilitate their risk management strategies. The Company enters into an interest rate swap with a customer, while at the same time entering into an offsetting interest rate swap with another financial institution. These interest rate swap transactions allows customers to effectively fix the interest rate on their loans. Customer loan derivative income is recognized for the upfront fee paid by the customer at origination. These swaps are designated as economic hedges and transactions are cleared through arrangements with third-party financial institutions.

Table of Contents

The Company’s mortgage banking activities result in two types of derivative instruments. Interest rate lock commitments are offered to residential loan customers, to allow them the ability to lock into a fixed interest rate prior to closing, for loans the Company intends to sell are classified as non-hedging derivatives. To offset this risk the Company often enters into offsetting forward sale commitments with national financial institutions to purchase the loans selected for sale under a best efforts or mandatory delivery contract accounted for as an economic hedge.

​

The Company’s floating-rate funding, certain hedging transactions and certain of the Company’s products, such as floating-rate loans and mortgages, determine the applicable interest rate or payment amount by reference to a benchmark rate, such as the London Interbank Offered Rate (“LIBOR”), or to an index, currency, basket or other financial metric. LIBOR and certain other benchmark rates are the subject of recent national, international, and other regulatory guidance and proposals for reform. Further accounting guidance has been issued regarding rate reform in relation to derivative instruments as further described in Note 1- Summary of Significant Accounting Policies under ASU 2020-04.

​

DEPOSIT ACTIVITIES

The Company offers a variety of deposit products to consumers, businesses and institutional customers with a wide range of interest rates and terms. The Company’s deposits consist of interest-bearing and non-interest-bearing demand accounts, savings accounts, money market deposit accounts, and certificates of deposit. The Company solicits deposits primarily in its market area, excluding brokered deposits. The Company primarily relies on competitive pricing policies, marketing and customer service to attract and retain deposits.

Additionally, customer related deposit fees are a significant source of fee income and principally derived from debit card interchange fees earned from transaction fees that merchants pay whenever a customer uses a debit card to make a purchase. Customer deposit fees are also earned from a variety of deposit accounts with various fee schedules and terms, which are designed to meet the customer’s financial needs. Other depositor related fee services provided to customers include ATMs, remote deposit capture, ACH origination, wire transfers, internet bill pay, and other cash management services.

The Company manages pricing of deposits in keeping with the Company’s asset/liability management, liquidity and profitability objectives, subject to market competitive factors. Based on experience, the Company believes that their deposits are relatively stable sources of funds. Despite this stability, the Company’s ability to attract and maintain these deposits and rates are significantly affected by market conditions.

The following table presents the average balances and weighted average rates for deposits for the three years indicated:

BORROWING ACTIVITIES

The Company may utilize borrowings as an alternative source of funds which can be invested at a positive interest rate spread when the Company desires additional capacity to fund loan demand or when they meet the Company’s asset/liability management goals to diversify funding sources and enhance interest rate risk management.

​

The Company’s borrowings historically have included advances from the Federal Home Loan Bank of Boston ("FHLB"), securities sold under repurchase agreements, and a correspondent bank unsecured line of credit. The Company also has the ability to borrow from the Federal Reserve Bank of Boston ("FRB"), which was used as a lending facility for Paycheck Protection Program (“PPP”) loans, as well as through unsecured federal funds lines with a correspondent bank. The Company may obtain advances from the FHLB by collateralizing the advances with certain loans and investment securities of the Company. These advances may be made pursuant to several different credit programs, each of which has its own interest rate, range of maturities and call features.

​

The Company has $60 million in subordinated notes to accredited investors that provides funds for ongoing operations and future growth. Subordinated notes consist of $40 million issued in November 2019 and an additional $20 million from the Lake Sunapee acquisition.

Certain Laws and Regulations Applicable to the Company

The BHC Act and other federal laws subject bank holding companies to particular restrictions on the types of activities in which the Company may engage, and to a range of supervisory requirements and activities, including regulatory enforcement actions for violations of laws and regulations. Below is a summary of certain provisions of the BHC Act and certain other laws and regulations applicable to the Company. These laws or regulations may be amended or changed by Congress or through other governmental or legal processes, which could have a material effect on the results of the Company.

Permitted Activities

Generally, bank holding companies are prohibited under the BHC Act from engaging in non-banking activities, or acquiring direct or indirect control of any company engaged in non-banking activities. The Federal Reserve Board has allowed by regulation some exceptions based on activities closely related to banking including: (i) making or servicing loans; (ii) performing certain data processing services; (iii) providing discount brokerage services; (iv) acting as fiduciary,

14

Table of Contents

investment or financial advisor; and (v) acquiring a savings and loan association whose direct and indirect activities are limited to those permitted for bank holding companies. The Federal Reserve Board has the authority to require a bank holding company to terminate an activity or terminate control of or liquidate or divest certain subsidiaries or affiliates when the Federal Reserve Board believes the activity or the control of the subsidiary or affiliate constitutes a significant risk to the financial safety, soundness, or stability of any of its banking subsidiaries.

​

A bank holding company that qualifies and elects to become a financial holding company is permitted to engage in additional activities that are financial in nature or incidental or complementary to financial activity. The Company currently has no plans to make a financial holding company election.

Safe and Sound Banking Practices

Bank holding companies and their non-banking subsidiaries are prohibited from engaging in activities that represent unsafe and unsound banking practices. For example, under certain circumstances the Federal Reserve Board’s Regulation Y requires a holding company to give the Federal Reserve Board prior notice of any redemption or repurchase of its own equity securities if the consideration to be paid, together with the consideration paid for any repurchases during the preceding 12 months, is equal to 10% or more of the company’s consolidated net worth. The Federal Reserve Board may oppose the transaction if it believes that the transaction would constitute an unsafe or unsound practice or would violate a regulation. As another example, a holding company is prohibited from impairing its subsidiary bank’s safety and soundness by causing the bank to make funds available to non-banking subsidiaries or their customers if the Federal Reserve Board believes it not prudent to do so. The Federal Reserve Board has the power to assess civil money penalties for knowing or reckless violations, if the activities leading to a violation caused a substantial loss to a depository institution. Potential penalties are as high as $1,000,000 for each day the activity continues.

Dividends

Dividends from the Bank are the Company’s principal source of cash revenues. The Company’s earnings and activities are affected by federal and state legislation, regulations, local legislative and administrative bodies, and decisions of courts in the jurisdictions in which business is conducted. These include limitations on the ability of the Bank to pay dividends to the Company and the Company’s ability to pay dividends to its stockholders. It is the policy of the Federal Reserve Board that bank holding companies should pay cash dividends on common stock only out of income available over the past year and only if prospective earnings retention is consistent with the organization’s expected future needs and financial condition. The policy provides that bank holding companies should not maintain a level of cash dividends that undermines the bank holding company’s ability to serve as a source of strength to its banking subsidiary. Consistent with such policy, a banking organization should have comprehensive policies on dividend payments that clearly articulate the organization’s objectives and approaches for maintaining a strong capital position and achieving the objectives of the policy statement.

The FDIC 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. Federal law also prohibits the payment of dividends by a bank that will result in the bank failing to meet its applicable capital requirements on a pro forma basis. Maine law requires the approval of the BFI for any dividend that would reduce a bank’s capital below prescribed limits.

Source of Strength

In accordance with Federal Reserve Board policy, the Company is expected to act as a source of financial and managerial strength to the Bank. Section 616 of the Dodd-Frank Wall Street Reform and Consumer Protection Act (“Dodd-Frank Act”) codifies the requirement that bank holding companies serve as a source of financial strength to their subsidiary depository institutions. Under this policy, the holding company is expected to commit resources to support its bank subsidiary, including at times when the holding company may not be in a financial position to provide it. As discussed below, the Company could be required to guarantee the capital plan of the Bank if it becomes undercapitalized for purposes of banking regulations. Any capital loans by a bank holding company to its subsidiary bank are subordinate in right of payment to deposits and to certain other indebtedness of such subsidiary bank. The BHC Act provides that, 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 priority of payment.

Anti-tying Restrictions

Bank holding companies and their affiliates are prohibited from tying the provision of services, such as extensions of credit, to other services offered by a holding company or its affiliates.

Mergers & Acquisitions

The BHC Act, the federal Bank Merger Act, the laws of the State of Maine applicable to financial institutions and other federal and state statutes regulate acquisitions of banks and their holding companies. The BHC Act generally limits acquisitions by bank holding companies to banks and companies engaged in activities that the Federal Reserve Board has determined to be so closely related to banking as to be a proper incident thereto. The BHC Act requires every bank holding company to obtain the prior approval of the Federal Reserve Board before (i) acquiring more than 5% of the voting stock of any bank or other bank holding company, (ii) acquiring all or substantially all of the assets of any bank or bank holding company, or (iii) merging or consolidating with any other bank holding company.

In reviewing applications seeking approval of merger and acquisition transactions, the bank regulatory authorities generally consider, among other things, the competitive effect and public benefits of the transactions, the financial and managerial resources and future prospects of the combined organization (including the capital position of the combined organization), the applicant’s performance record under the federal Community Reinvestment Act (see Community Reinvestment Act included in Item I), fair housing laws and the effectiveness of the subject organizations in combating money laundering activities.

Limitations on Acquisitions of Bar Harbor Bankshares Common Stock

The federal Change in Bank Control Act prohibits a person or group of persons from acquiring “control” of a bank holding company unless the appropriate federal bank regulator has been notified and has not objected to the transaction. Under a rebuttable presumption established by the federal bank regulator, 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 constitute the acquisition of control of a bank holding company. In addition, the BHC Act prohibits any company from acquiring control of a bank or bank holding company without first having obtained the approval of the federal bank regulator. Among other circumstances, under the BHC Act, a company has control of 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 federal bank regulator has determined, after notice and opportunity for hearing, that the company has the power to exercise a controlling influence over the management or policies of the bank or bank holding company.

Transactions with Affiliates

The holding company and the Bank are considered “affiliates” of each other under the Federal Reserve Act, and transactions between a bank and its affiliates are subject to certain restrictions, under Sections 23A and 23B of the Federal Reserve Act and the Federal Reserve Board’s implementing Regulation W. Generally, Sections 23A and 23B: (1) limit the extent to which an insured depository or its subsidiaries may engage in covered transactions (a) with an affiliate (as defined in such sections) to an amount equal to 10% of such institution’s capital and surplus, and (b) with all affiliates, in the aggregate to an amount equal to 20% of such capital and surplus; and (2) require all transactions with an affiliate, whether or not covered transactions, to be on terms substantially the same, or at least as favorable to the institution or subsidiary, as the terms provided or that would be provided to a non-affiliate. The term “covered transaction” includes the making of loans, purchase of assets, issuance of a guarantee and other similar types of transactions.

State Law Restrictions

As a Maine corporation, the Company is subject to certain limitations and restrictions under applicable Maine corporate law. For example, state law restrictions in Maine include limitations and restrictions relating to indemnification of directors, distributions and dividends to stockholders, transactions involving directors, officers or interested stockholders, maintenance of books, records, and minutes, and observance of certain corporate formalities. Further, as a Maine financial institution holding company, the Company is also subject to certain requirements and restrictions under applicable Maine banking law.

Capital Adequacy and Prompt Corrective Action

In July 2013, the Federal Reserve Board, the FDIC and the Office of the Comptroller of the Currency issued final rules (the “Capital Rules”) that established the current capital framework for U.S. banking organizations. The Capital Rules generally implement the Basel Committee on Banking Supervision’s December 2010 final capital framework referred to as “Basel III” for strengthening international capital standards. In addition, the Capital Rules implement certain provisions of the Dodd-Frank Act, including the requirements of Section 939A to remove references to credit ratings from the federal banking agencies’ rules. The Capital Rules substantially revised the risk-based capital requirements applicable to bank holding companies and their depository institution subsidiaries. The risk based capital guidelines are designed to make regulatory capital requirements sensitive to differences in risk profiles among banks and bank holding companies, to account for off-balance sheet exposures and to minimize disincentives for holding liquid, low-risk assets.

The Capital Rules: (i) require a capital measure called “Common Equity Tier 1” (“CET1”) and related regulatory capital ratio of CET1 to risk-weighted assets; (ii) specify that Tier 1 capital consists of CET1 and “Additional Tier 1 capital” instruments meeting certain revised requirements; (iii) mandate that most deductions/adjustments to regulatory capital measures be made to CET1 and not to the other components of capital; and (iv) expand the scope of the deductions from and adjustments to capital as compared to existing regulations. The Capital Rules revised the definitions and the components of regulatory capital and impacted the calculation of the numerator in banking institutions’ regulatory capital ratios.

The Capital Rules prescribe a standardized approach for risk weightings, generally ranging from 0% for U.S. government and agency securities to 600% for certain equity exposures, resulting in higher risk weights for a variety of asset classes.

Pursuant to Section 38 of the Federal Deposit Insurance Act (“FDI Act”), federal banking agencies are required to take “prompt corrective action” should an insured depository institutions fail to meet certain capital adequacy standards. At each successive lower capital category, an insured depository institution is subject to more restrictions and prohibitions, including restrictions on growth, restrictions on interest rates paid on deposits, restrictions or prohibitions on payment of dividends and restrictions on the acceptance of brokered deposits. Furthermore, if an insured depository institution is classified in one of the undercapitalized categories, it is required to submit a capital restoration plan to the appropriate federal banking agency, and the holding company must guarantee the performance of that plan. Based upon its capital levels, a bank that is classified as well-capitalized, adequately capitalized, or undercapitalized may be treated as though it were in the next lower capital category if the appropriate federal banking agency, after notice and opportunity for hearing, determines that an unsafe or unsound condition, or an unsafe or unsound practice, warrants such treatment.

For purposes of Section 38 of the FDI Act, for an insured depository institution to be well-capitalized it must have a:

(i) total risk-based capital ratio of at least 10%,

(ii) Tier 1 risk-based capital ratio of at least 8%,

(iii) CET1 risk-based capital ratio of at least 6.5%, and

(iv) leverage ratio of at least 5%.

​

Both the Company and the Bank have always maintained the capital ratios and leverage ratio above the levels to be considered quantitatively well-capitalized. For information regarding the capital ratios and leverage ratio of the Company and the Bank as of December 31, 2020, and December 31, 2019, see the discussion under the section captioned Capital Resources included in Item 7 - Management’s Discussion and Analysis of Financial Condition and Results of Operations included in Item 7 and Note 13 - Shareholders’ Equity and Earnings Per Common Share in the Notes to Consolidated Financial Statements, elsewhere in this report.

Significant Banking Regulations Applicable to the Bank

Deposit Insurance

The Bank’s deposit accounts are fully insured by the Deposit Insurance Fund ("DIF") of the FDIC up to the deposit insurance limits set forth in applicable law and regulations.

The FDIC uses a risk-based assessment system that imposes insurance premiums based upon a risk matrix that accounts for a bank’s capital level and supervisory rating (CAMELS rating). The risk matrix uses different risk categories

17

Table of Contents

distinguished by capital levels and supervisory ratings. The base for deposit insurance assessments is consolidated average assets less average tangible equity. Assessment rates are calculated using formulas that take into account the risk of the institution being assessed. The FDIC may increase or decrease the assessment rate schedule in order to manage the DIF to prescribed statutory target levels. An increase in the risk category for the Bank or in the assessment rates could have an adverse effect on the Bank’s and consequently the Company’s earnings. The FDIC may terminate deposit insurance if it determines the institution involved has engaged in or is engaging in unsafe or unsound banking practices, is in an unsafe or unsound condition, or has violated applicable laws, regulations or orders.

In addition to deposit insurance assessments, the FDI Act provides for additional assessments to be imposed on insured depository institutions to pay for the cost of Financing Corporation (“FICO”) funding. The FICO is a mixed-ownership government corporation established by the Competitive Equality Banking Act of 1987, whose sole purpose was to function as a financing vehicle for the now defunct Federal Savings & Loan Insurance Corporation. The FICO assessments are adjusted quarterly to reflect changes in the assessment base of the DIF and do not vary depending upon a depository institution’s capitalization or supervisory evaluation. The current annualized assessment rate is approximately six basis points and the rate is adjusted quarterly. These assessments continued until the FICO bonds matured in 2020.

Consumer Financial Protection

The Company is subject to a number of federal and state consumer protection laws that govern its relationship with its customers. These laws include, for example, the Equal Credit Opportunity Act, the Fair Credit Reporting Act, the Truth in Lending Act, the Truth in Savings Act, the Electronic Fund Transfer Act, the Expedited Funds Availability Act, the Home Mortgage Disclosure Act, the Fair Housing Act, the Real Estate Settlement Procedures Act, the Fair Debt Collection Practices Act, the Right to Financial Privacy Act, the Service Members Civil Relief Act and these federal laws’ respective state law counterparts, as well as state usury laws and laws regarding unfair and deceptive acts and practices. These and other federal laws, among other things, require disclosures of the cost of credit and terms of deposit accounts, provide substantive consumer rights, prohibit discrimination in credit transactions, regulate the use of credit report information, provide financial privacy protections, prohibit unfair, deceptive and abusive practices, restrict the Bank’s ability to raise interest rates and subject the Bank to substantial regulatory oversight. Violations of applicable consumer protection laws can result in significant potential liability from litigation brought by customers, including actual damages, restitution and attorneys’ fees.

Further, the Consumer Financial Protection Bureau ("CFPB") has broad rulemaking authority for a wide range of consumer financial laws that apply to all banks, including, among other things, the authority to prohibit “unfair, deceptive or abusive” acts and practices. Abusive acts or practices are defined as those that materially interfere with a consumer’s ability to understand a term or condition of a consumer financial product or service or take unreasonable advantage of a consumer’s: (i) lack of understanding on the part of the consumer of the material risks, costs, or conditions of the product or service, (ii) inability of the consumer to protect its interests in selecting or using a consumer financial product or service, or (iii) reasonable reliance on a covered entity to act in the consumer’s interests.

Neither the Dodd-Frank Act nor the individual consumer financial protection laws prevent states from adopting stricter consumer protection standards.

Brokered Deposit Restrictions

Under the FDIC Improvement Act, banks may be restricted in their ability to accept brokered deposits, depending on their classification. “Well-capitalized” institutions are permitted to accept brokered deposits, but all banks that are not well- capitalized could be restricted from accepting such deposits. The Bank is currently well-capitalized and not restricted from accepting brokered deposits.

Community Reinvestment Act

The Community Reinvestment Act of 1977 (“CRA”), requires depository institutions to assist in meeting the credit needs of their market areas consistent with safe and sound banking practice. Under the CRA, each depository institution is required to help meet the credit needs of its market areas by, among other things, providing credit to low- and moderate-income individuals and communities. These factors are also considered in evaluating mergers, acquisitions and applications to open a branch or facility. The applicable federal regulators regularly conduct CRA examinations to assess

18

Table of Contents

the performance of financial institutions and assign one of four ratings to the institution’s records of meeting the credit needs of its community. During its last examination, the Bank received a CRA rating of “satisfactory”.

Insider Credit Transactions

Section 22(h) of the Federal Reserve Act and its implementing Regulation O, restricts loans to directors, executive officers, and principal stockholders (“insiders”). Under Section 22(h), loans to insiders and their related interests may not exceed, together with all other outstanding loans to such persons and affiliated entities, the institution’s total capital and surplus. Loans to insiders above specified amounts must receive the prior approval of the Board of Directors. Further, under Section 22(h) of the FRA, loans to directors, executive officers and principal stockholders must be made on terms substantially the same as offered in comparable transactions to other persons, except that such insiders may receive preferential loans made under a benefit or compensation program that is widely available to the bank’s employees and does not give preference to the insider over the employees. Section 22(g) of the FRA places additional limitations on loans to executive officers. A violation of these restrictions may result in the assessment of substantial civil monetary penalties on the affected bank or any officer, director, employee, agent or other person participating in the conduct of the affairs of that bank, the imposition of a cease and desist order, and other regulatory sanctions.

Safety and Soundness

Under the FDI Act, each federal banking agency has prescribed, by regulation, non-capital safety and soundness standards for institutions under its authority. These standards cover internal controls, information and internal audit systems, loan documentation, credit underwriting, interest rate exposure, asset growth, compensation, fees and benefits, such other operational and managerial standards as the agency determines to be appropriate, and standards for asset quality, earnings and stock valuation. An institution that fails to meet these standards must develop a plan acceptable to the agency, specifying the steps that the institution will take to meet the standards. Failure to submit or implement such a plan may subject the institution to regulatory sanctions.

Financial Privacy

Section V of the Gramm-Leach-Bliley Act ("GLBA") and its implementing regulations require all financial institutions, including the Company and the Bank and the Bank’s subsidiaries, to adopt privacy policies, restrict the sharing of nonpublic customer data with non-affiliated parties at the customer’s request, limit the reuse of certain consumer information received from non-affiliated financial institutions, and establish procedures and practices to protect customer data from unauthorized access. In addition, the Fair Credit Reporting Act (“FCRA”), as amended by the Fair and Accurate Credit Transactions Act of 2003 (the "FACT Act”), includes many provisions affecting the Company, Bank, and/or their affiliates, including provisions concerning obtaining consumer reports, furnishing information to consumer reporting agencies, maintaining a program to prevent identity theft, sharing of certain information among affiliated companies, and other provisions. The FACT Act requires entities subject to FCRA to notify their customers if they report negative information about them to a credit bureau or if they are granted credit on terms less favorable than those generally available. The CFPB and the Federal Trade Commission (“FTC”) have extensive rulemaking authority under the FACT Act, and the Company and the Bank are subject to the rules that have been promulgated under the FACT Act, including rules requiring financial institutions with covered accounts (e.g. consumer bank accounts and loans) to develop, implement, and administer an identity theft protection program, as well as rules regarding limitations on affiliate marketing and implementation of programs to identify, detect and mitigate certain identity theft red flags. The Company has developed policies and procedures for itself and its subsidiaries, including the Bank, and believes it is in compliance with all privacy, information sharing, and notification provisions of the GLBA and the FACT Act. The Bank is also subject to data security standards, privacy and data breach notice requirements, primarily those issued by the FDIC, as well as under state laws.

Anti-Money Laundering Initiatives and the USA Patriot Act

A major focus of governmental policy on financial institutions over the last two decades has been combating money laundering and terrorist financing. The USA PATRIOT Act of 2001 (“USA Patriot Act”), substantially broadened the scope of United States anti-money laundering laws and regulations by imposing significant new compliance and due diligence obligations, creating new crimes and penalties and expanding the extra-territorial jurisdiction of the United States. The U.S. Treasury Department has issued a number of regulations that apply various requirements of the USA Patriot Act to financial institutions such as the Bank. These regulations impose obligations on financial institutions to maintain appropriate policies, procedures and controls to detect, prevent and report money laundering and terrorist financing and to verify the identities of their customers. Financial institutions are also prohibited from entering into

19

Table of Contents

specified financial transactions and account relationships and must use enhanced due diligence procedures in their dealings with certain types of high-risk customers and implement a written customer identification program. Financial institutions must take certain steps to assist government agencies in detecting and preventing money laundering and report certain types of suspicious transactions. Regulatory authorities routinely examine financial institutions for compliance with these obligations, and failure of a financial institution to maintain and implement adequate programs to combat money laundering and terrorist financing, or to comply with all of the relevant laws or regulations, can have serious legal and reputational consequences for the institution.

Office of Foreign Assets Control Regulation

The United States has imposed economic sanctions that affect transactions with designated foreign countries, nationals and others. These are typically known as the “OFAC” rules based on their administration by the U.S. Treasury Department Office of Foreign Assets Control (“OFAC”). The OFAC-administered sanctions targeting countries 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 transactions relating to making investments in, or providing investment-related advice or assistance to, a sanctioned country; and (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). Blocked assets (e.g., property and bank deposits) cannot be paid out, withdrawn, set off or transferred in any manner without a license from OFAC. The Company is responsible for, among other things, blocking accounts of, and transactions with, such targets and countries, prohibiting unlicensed trade and financial transactions with them and reporting blocked transactions after their occurrence. Failure to comply with these sanctions could have serious legal and reputational consequences.

Guidance on Sound Compensation Policies

The Dodd-Frank Act requires publicly traded companies to give stockholders a non-binding vote on executive compensation at least every three years (the so-called “say-on-pay vote”) and on so-called “golden parachute” payments in connection with approvals of mergers and acquisitions. In addition, the Dodd-Frank Act requires publicly traded companies to give stockholders a non-binding vote, at least once every six years, on how frequently to hold the “say on pay” vote.

The Dodd-Frank Act also requires the federal banking agencies and the SEC to establish joint regulations or guidelines prohibiting incentive-based payment arrangements at specified regulated entities with at least $1 billion in total consolidated assets that encourage inappropriate risks by providing an executive officer, employee, director or principal shareholder with excessive compensation, fees, or benefits that could lead to material financial loss to the entity. The federal banking agencies and the SEC most recently proposed such regulations in 2016, but the regulations have not yet been finalized. If the regulations are adopted in the form initially proposed, they will restrict the manner in which executive compensation is structured.

Changing Regulatory Structure and Future Legislation and Regulation

Congress may enact further legislation that affects the regulation of the financial services industry, and state legislatures may enact further legislation affecting the regulation of financial institutions. Federal and state regulatory agencies also periodically propose and adopt changes to their regulations or change the manner in which existing regulations are applied. The Company cannot predict the substance or impact of pending or future legislation or regulations, or the application thereof, although enactment of the proposed legislation could impact the regulatory structure under which the Company operates and may significantly increase costs, impede the efficiency of internal business processes, require an increase in regulatory capital, require modifications to the Company’s business strategy, and limit the Company’s ability to pursue business opportunities in an efficient manner. A change in statutes, regulations or regulatory policies applicable to the Company or any of its subsidiaries could have a material effect on its business.

Other Laws and Regulations

The Company is not only subject to federal laws applicable to it, it is also subject to the rules and regulations of the various federal agencies charged with the responsibility of implementing these federal laws.

ITEM 1A. RISK FACTORS

An investment in the Company involves risk, some of which, including market, liquidity, credit, operational, legal, compliance, reputational and strategic risks, could be substantial and is inherent in the Company’s business. This risk also includes the possibility that the value of the investment could decrease considerably, and dividends or other distributions concerning the investment could be reduced or eliminated. Discussed below are risk factors that could adversely affect financial results and condition, as well as the value of, and return on investments made in the Company. Although the Company believes that these risks are the most important for you to consider, you should read this section in conjunction with the Consolidated Financial Statements, the notes to those Financial Statements and management’s discussion and analysis of financial condition and results of operations.

Risks Related to the Company’s Lending Activities

Deterioration in local economies or real estate market may adversely affect financial performance.

The Company serves individuals and businesses located in Maine, New Hampshire, and Vermont. A substantial portion of the loan portfolio is secured by real estate in these areas and the value of the associated collateral is subject to local real estate market conditions. Furthermore, many customers in the hospitality industry rely upon a high number of tourists to vacation destinations and attractions within the Company’s markets. The Company’s success is largely dependent on the economic conditions, including employment levels, population growth, income levels, savings trends and government policies in those market areas. A downturn in the local economies may adversely affect collateral values, sources of funds, and demand for products, all of which could have a negative impact on results of operations, financial condition and business expansion.

High concentrations of commercial loans may increase exposure to credit loss upon borrower default.

As of December 31, 2020, approximately 60% of the Banks’s loan portfolio consisted of commercial real estate, commercial and industrial and construction loans. Commercial loan portfolio concentration generally exposes lenders to greater risk of delinquency and loss than residential real estate loans because repayment of the loans often depends on the successful operation and income streams from the property. Commercial loans typically involve larger balances to single borrowers or groups of related borrowers as compared to residential real estate loans. As the Bank’s loan portfolio contains a significant number of large commercial loans, the deterioration of one or a few of these loans could cause a significant increase in non-performing loans, provision for loan losses, and/or an increase in loan charge-offs, all of which could adversely affect the Company’s financial condition and results of operations.

Prepayments of loans may negatively impact the Company’s business. Generally, customers may prepay the principal amount of their outstanding loans at any time.

The speeds at which such prepayments occur, as well as the size of such prepayments, are within the customers’ discretion. Fluctuations in interest rates, in certain circumstances, may also lead to high levels of loan prepayments, which may also have an adverse impact on net interest income. If customers prepay the principal amount of their loans, and the Company is 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 results of operations and financial condition.

Secondary mortgage market conditions may adversely affect financial condition and earnings.

The secondary mortgage markets are impacted by interest rates and investor demand for residential mortgage loans and increased investor yield requirements for these loans. These conditions may fluctuate in the future. As a result, a prolonged period of secondary market illiquidity may reduce the Company’s loan production volumes, change loan portfolio composition, and reduce operating results. Secondary markets are affected by Fannie Mae, Freddie Mac, and Ginny Mae (collectively, the "Agencies") for loan purchases that meet their conforming loan requirements. These agencies could limit purchases of conforming loans due to capital constraints, changes in conforming loan criteria or other factors. Proposals to reform mortgage finance could affect the role of the Agencies and the market for conforming loans.

The Bank is exposed to risk of environmental liabilities with respect to properties to which it takes title.

In the course of business, the Bank may own or foreclose and take title to real estate that may be subject to environmental liabilities with respect to subject property. As a result, the Company may be held liable for property damage, personal

21

Table of Contents

injury, investigation and restoration costs. The cost associated with investigation or restoration activities could be substantial. In addition, as the owner or former owner of a contaminated site, the Company may be subject to common law claims by third parties based on damages and costs resulting from environmental contamination emanating from the property.

Greater than anticipated credit losses in the loan portfolios may adversely affect earnings.

Credit losses are inherent in the business of making loans and could have a material adverse effect on operating results. The Company makes various assumptions and judgments about the collectability of the loan portfolio and provides an allowance for loan losses based on a number of factors. The allowance for loan losses is evaluated on a periodic basis using current information, including the quality of the loan portfolio, economic conditions, values of the underlying collateral and the level of non-accrual loans. Although the Company believes the allowance for loan losses is appropriate to absorb probable losses in the loan portfolio, this allowance may not be adequate. Increases in the allowance will result in an expense for the period, thereby reducing reported net income.

The Financial Accounting Standards Board has issued Accounting Standards Update 2016-13, Measurement of Credit Losses on Financial Instruments. This standard, often referred to as CECL requires companies to recognize an allowance for credit losses using a new current expected credit loss model. Any increase in the allowance for credit losses or expenses incurred to determine the appropriate level of the allowance for loan losses may have a material adverse effect on the Company’s financial condition and results of operations. This is discussed further in Note 1- Summary of Significant Accounting Policies of the Consolidated Financial Statements in this Annual Report on Form 10-K. The Company has adopted CECL as of January 1, 2021.

Risks Related to the Company’s Business

The COVID-19 pandemic may adversely impact our business and financial results, as it is highly uncertain and cannot be predicted, including the scope and duration of the pandemic and actions taken by governmental authorities in response to the pandemic.

The COVID-19 pandemic is creating extensive disruptions to the economy and to the lives of individuals. Governments, businesses, and the public are taking unprecedented actions to contain the spread of COVID-19 and to mitigate its effects, including quarantines, travel bans, shelter-in-place orders, closures of businesses and schools, fiscal stimulus, and legislation designed to deliver monetary aid and other relief. While the scope, duration, and full effects of COVID-19 are rapidly evolving, the pandemic and related efforts to contain it have disrupted economic activity, adversely affected the functioning of financial markets, impacted interest rates, increased economic and market uncertainty, and disrupted trade and supply chains. If these effects continue for a prolonged period or result in sustained economic stress or recession, many of the risk factors identified in our Form 10-K could be exacerbated and such effects could have an adverse impact on us in a number of ways related to credit quality, collateral values, customer demand, funding, operations, interest rate risk, and human capital.

Expansion, growth, and acquisitions could negatively impact earnings if not successful.

The Company may grow organically both by geographic expansion and through business line expansion, as well as through acquisitions. Success of these activities depends on the Company’s ability to continue to maintain and develop an infrastructure appropriate to support and integrate such growth. Success may also depends on acceptance of the Bank by customers in these new markets and, in the case of expansion through acquisitions, these factors include the long-term recruitment and retention of key personnel and acquired customer relationships. Profitability depends on whether the marginal revenue generated in the new markets will offset the increased expenses of operating a larger entity, with more staff, more locations, and more product offerings. Failure to achieve any of these success factors may have a negative impact on the Company’s financial condition and results of operations.

The Company may be adversely affected by continuous technological change.

The financial services industry is continually undergoing rapid technological change with frequent introductions of new technology-driven products and services. The effective use of technology increases efficiency and enables financial institutions to better serve customers and to reduce costs. The Company’s future success depends, in part, upon its ability to address the needs of its customers by using technology to provide products and services that will satisfy customer demands, as well as to create additional operational efficiencies.

22

Table of Contents

The introduction of new products and services can entail significant time and resources. The Company’s failure to manage risks and uncertainties associated with new products and services exposes it to enhanced risk of operational lapses which may result in the recognition of financial statement liabilities. Regulatory and internal control requirements, capital requirements, competitive alternatives, vendor relationships and shifting market preferences may also determine if such initiatives can be brought to market in a manner that is timely and attractive to the Company’s clients. Products and services relying on internet and mobile technologies may expose the Company to fraud and cybersecurity risks. Failure to successfully manage these risks in the development and implementation of new products or services could have a material adverse effect on the Company’s business and reputation.

​

Strong competition within the Company’s markets may significantly impact profitability.

The Company competes with an ever-increasing array of financial service providers. See the section entitled “Competition” of Item 1 of this Annual Report on Form 10-K for additional competitor information. Competition from nationwide banks, as well as local institutions, continues to mount in the Company’s markets. To compete, the Company focuses on quality customer service, making decisions at the local level, maintaining long-term customer relationships, building customer loyalty, and providing products and services designed to address the specific needs of customers. Failure to perform in any of these areas could significantly weaken the Company’s competitive position, which could adversely affect growth and profitability.

Market changes may adversely affect demand for services and impact revenue, costs, and earnings.

Channels for servicing the Company’s customers are evolving rapidly, with less reliance on traditional branch facilities, increased use of e-commerce channels, and demand for universal bankers and other relationship managers who can service multiple product lines. The Company has an ongoing process for evaluating the profitability of its branch system 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. The Company competes with larger financial institutions who are rapidly evolving their service channels and escalating the costs of evolving the service process.

Disruptions to the Company’s information systems and security breaches may adversely affect its business and reputation.

In the ordinary course of business, the Company relies on electronic communications and information systems to conduct its businesses and to store sensitive data, including financial information regarding its customers. The integrity of information systems are under significant threat from cyberattacks by third parties, including through coordinated attacks sponsored by foreign nations and criminal organizations to disrupt business operations and other compromises to data and systems for political or criminal purposes. The Company employs an in-depth, layered, defense approach that leverages people, processes and technology to manage and maintain cybersecurity controls. Notwithstanding the strength of defensive measures, the threat from cyberattacks is severe, attacks are sophisticated and attackers respond rapidly to changes in defensive measures. Cybersecurity risks may also occur with the Company’s third-party service providers, and may interfere with their ability to fulfill their contractual obligations to us, with additional potential for financial loss or liability that could adversely affect the Company’s financial condition or results of operations. The Company offers its customers the ability to bank remotely and provide other technology-based products and services, which services include the secure transmission of confidential information over the Internet and other remote channels. To the extent that the Company’s customers’ systems are not secure or are otherwise compromised, its network could be vulnerable to unauthorized access, malicious software, phishing schemes and other security breaches. To the extent that the Company’s activities or the activities of its clients or third-party service providers involve the storage and transmission of confidential information, security breaches and malicious software could expose the Company to claims, regulatory scrutiny, litigation and other possible liabilities.

While to date the Company has not experienced a significant compromise, significant data loss or material financial losses related to cybersecurity attacks, the Company’s systems and those of its customers and third-party service providers, are under constant threat and may experience a significant event in the future. The Company may suffer material financial losses related to these risks or be subject to liability for compromises to its customers or third-party providers. Any such losses or liabilities could adversely affect the Company’s financial condition or results of operations, and could expose us to reputation risk, the loss of client business, increased operational costs, as well as additional regulatory scrutiny, possible litigation, and related financial liability. These risks also include possible business interruption, including the inability to access critical information and systems.

Table of Contents

The Company’s operations is reliant on outside vendors.

The Company’s operations is dependent on the use of certain outside vendors for its day-to-day operations. The vendor may not perform in accordance with established performance standards required in its agreements for any number of reasons including a change in the vendor’s senior management, financial condition, product line or mix and how they support existing customers, or simply change their strategic focus putting the Company at risk. While the Company has a comprehensive policies and procedures in place to mitigate risk in all phases of vendor management from selection, to performance monitoring, the failure of a vendor to perform in accordance with contractual agreements could be disruptive to its business, which could have a material adverse effect on its financial condition and results of operations.

The Company is subject to a variety of operational risks, including reputational risk, and the risk of fraud or theft by employees or outsiders, which may adversely affect the Company’s business and results of operations.

The Company is exposed to many types of operational risks, including reputational risk, legal and compliance risk, the risk of fraud or theft by employees or outsiders, and unauthorized transactions by employees or operational errors, including clerical or record-keeping errors or those resulting from faulty or disabled computer or telecommunications systems. If personal, non-public, confidential, or proprietary information of customers in the Company’s possession were to be mishandled or misused, the Company could suffer significant regulatory consequences, reputational damage, and financial loss.

Because the nature of the financial services business involves a high volume of transactions, certain errors may be repeated or compounded before they are discovered and successfully rectified. The Company’s necessary dependence upon automated systems to record and process transactions and its large transaction volume may further increase the risk that technical flaws or employee tampering or manipulation of those systems will result in losses that are difficult to detect. The Company may also be subject to disruptions of its operating systems arising from events that are wholly or partially beyond its control (i.e., computer viruses or electrical or telecommunications outages, natural disaster, disease pandemics, or other damage to property or physical assets), which may give rise to disruption of service to customers and to financial loss or liability. The Company is further exposed to the risk that its external vendors may be unable to fulfill their contractual obligations (or will be subject to the same risk of fraud or operational errors by their respective employees) and to the risk that the Company’s vendors’ business continuity and data security systems prove to be inadequate. The occurrence of any of these risks could result in a diminished ability to operate (i.e., by requiring the Company to expend significant resources to correct the defect), as well as potential liability to clients, reputational damage, and regulatory intervention.

The Company may be adversely affected by the soundness of other financial institutions.

The Company’s ability to engage in routine funding transactions could be adversely affected by the actions and commercial soundness of other financial institutions. Bank and non-bank financial services companies are interrelated as a result of trading, clearing, counterparty and other relationships. The Company has exposure to different industries and counterparties through transactions with counterparties in the bank and non-bank financial services industries, including brokers and dealers, commercial banks, investment banks and other institutional clients. As a result, defaults by, or even rumors or questions about, one or more bank or non-bank financial services companies, or the bank or non-bank financial services industries generally, have led to market-wide liquidity problems and could lead to losses or defaults by us or by other institutions. These losses or defaults could have an adverse effect on the Company’s business, financial condition and results of operations.

The Company may be unable to attract and retain key personnel.

The Company’s success depends, in large part, on its ability to attract and retain key personnel. Competition for qualified personnel in the financial services industry can be intense and the Company and its subsidiaries may not be able to hire or retain the key personnel that it depends upon for success. In addition, the Bank’s rural geographic marketplace, combined with relatively expensive real estate purchase prices in the many tourist communities the Company serves, create additional risks for the Company’s ability to attract and retain key personnel. The unexpected loss of key personnel could have an adverse impact on the Company’s business because of their skills, knowledge of the markets in which the Company operates, years of industry experience and the difficulty of promptly finding qualified replacement personnel.

24

Table of Contents

The Company is subject to possible claims and litigation pertaining to fiduciary responsibilities.

From time to time, customers make claims and take legal action pertaining to the Company’s performance of its fiduciary responsibilities. Whether customer claims and legal action related to the Company’s performance of fiduciary responsibilities are founded or unfounded, if such claims and legal actions are not resolved in a favorable manner, they may result in significant financial liability and/or adversely affect the market perception of the Company and products and services as well as impact customer demand for products and services.

Societal responses to climate change could adversely affect the Company’s business and performance, including indirectly through impacts on the Company’s customers.

Concerns over the long-term impacts of climate change have led and will continue to lead to governmental efforts around the world to mitigate those impacts. Consumers and businesses also may change their behavior on their own as a result of these concerns. The Company and its customers will need to respond to new laws and regulations as well as consumer and business preferences resulting from climate change concerns. The Company and its customers may face cost increases, asset value reductions and operating process changes, among other impacts. The impact on the Company’s customers will likely vary depending on their specific attributes. In addition, the Company could face reductions in creditworthiness on the part of some customers or in the value of assets securing loans. The Company’s efforts to take these risks into account in making lending and other decisions may not be effective in protecting the Company from the negative impact of new laws and regulations or changes in consumer or business behavior.

​

Severe weather, natural disasters, acts of war or terrorism, and other external events could significantly impact the Company’s business and the business of its customers.

Severe weather, natural disasters, acts of war or terrorism, and other adverse external events could have a significant impact on the Company’s ability to conduct business. Such events could affect the stability of borrowers to repay outstanding loans, impair the value of collateral securing loans, cause significant property damage, result in loss of revenue and/or cause us to incur additional expenses. In particular, such events may have a particularly negative impact upon the business of customers who are engaged in the hospitality in the Company’s market area, which could have a direct negative impact on the Company’s business and results of operations.

Risks Related to Liquidity

​

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.

​

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

The Company and banking subsidiaries must maintain sufficient funds to respond to the needs of customers. To manage liquidity, the Company draws upon a number of funding sources in addition to core deposit growth, loan repayments and maturities of loans and securities. These sources include FHLB and FRB advances, proceeds from the sale of securities and loans and liquidity resources at the holding company. The Company’s ability to manage liquidity will be severely constrained if unable to maintain access to funding or if adequate financing is not available to accommodate future growth at acceptable costs. In addition, if the Company is required to rely more heavily on more expensive funding sources to support future growth, revenues may not increase proportionately to cover costs. In this case, operating margins and profitability would be adversely affected.

25

Table of Contents

The Company’s access to funds from subsidiaries may be restricted.

Bar Harbor Bankshares is a separate and distinct legal entity from the Bank and non-banking subsidiaries. Bar Harbor Bankshares depends on dividends, distributions and other payments from its banking and non-banking subsidiaries to fund dividend payments on its common stock, debt service of subordinated borrowings, fund stock repurchase program and to fund strategic initiatives or other obligations. The Company’s subsidiaries are subject to laws that authorize regulatory bodies to block or reduce the flow of funds from those subsidiaries to Bar Harbor Bankshares based on assertion that certain payments from subsidiaries are considered an unsafe or unsound practice.

​

Changes in the general economy or the financial markets could adversely affect financial performance.

A deterioration of general economic conditions could adversely affect local economies and have a negative impact on results of operations and financial condition. Deterioration or defaults made by issuers of the underlying collateral of investment securities may cause additional credit-related other-than-temporary impairment charges to the income statement. The Company’s ability to borrow from other financial institutions or to access the debt or equity capital markets on favorable terms or at all could be adversely affected by disruptions in the capital markets or other events, including actions by rating agencies or deteriorating investor expectations.

Monetary Policy and Economic Environment

The earnings of the Company are significantly affected by the monetary and fiscal policies of governmental authorities, including the Federal Reserve Board. Among the instruments of monetary policy used by the Federal Reserve Board to implement these objectives are open-market operations in U.S. Government securities and federal funds, changes in the discount rate on member bank borrowings, and changes in reserve requirements against member bank deposits. These instruments of monetary policy are used in varying combinations to influence the overall level of bank loans, investments, and deposits, and the interest rates charged on loans and paid for deposits. The Federal Reserve Board frequently uses these instruments of monetary policy, especially its open-market operations and the discount rate, to influence the level of interest rates, thereby affecting the strength of the economy, the level of inflation, or the price of the dollar in foreign exchange markets. The monetary policies of the Federal Reserve Board have had a significant effect on the operating results of banking institutions in the past and are expected to continue to do so in the future. It is not possible to predict the nature of future changes in monetary and fiscal policies, or the effect which they may have on the Company’s business and earnings.

Interest rate volatility could significantly reduce the Company’s profitability.

The Bank’s earnings and cash flows are largely dependent upon its net interest income. Net interest income is the difference between interest income earned on interest-bearing assets such as loans and securities and interest expense paid on interest-bearing liabilities such as deposits and borrowed funds. Interest rates are highly sensitive to many factors that are beyond the Company’s control, including general economic conditions, demand for loans, securities and deposits, policies of various governmental and regulatory agencies. Changes in monetary policy, including changes in interest rates, or the slope of the yield curve could influence not only the interest received on loans and securities and the amount of interest paid on deposits and borrowings, but such changes could also affect (i) the ability to originate loans and obtain deposits, (ii) the fair value of the Company’s financial assets and liabilities, and (iii) the average duration of loans and securities that are collateralized by mortgages. If the interest rates paid on deposits and other borrowings increase at a faster rate than the interest rates received on loans and other investments, net interest income, and therefore earnings, could be adversely affected. Earnings could also be adversely affected if the interest rates received on loans and other investments fall more quickly than the interest rates paid on deposits and other borrowings. If interest rates decline, the Bank’s higher- rate loans and investments may be subject to prepayment risk, which could negatively impact its net interest margin. Conversely, if interest rates increase, the Bank’s loans and investment securities may be subject to extension risk, which could negatively impact its net interest margin as well.

Loss of deposits or a change in deposit mix could increase the cost of funding.

Deposits are a low cost and stable source of funding. The Company competes with banks and other financial institutions for deposits. Funding costs may increase if deposits are lost and are forced to replace them with more expensive sources of funding, if customers shift their deposits into higher cost products or if the Company needs to raise interest rates to avoid losing deposits. Higher funding costs reduce the net interest margin, net interest income and net income.

Risks Related to Regulatory Matters

The Company is subject to extensive government regulation and supervision, which may interfere with the ability to conduct business and may negatively impact financial results.

The Company is subject to extensive federal and state regulation and supervision. Banking regulations are primarily intended to protect depositors’ funds, the Federal Deposit Insurance Fund and the safety and soundness of the banking system as a whole, not stockholders. These regulations affect the Company’s lending practices, capital structure, investment practices, dividend policy and growth, among other things. Congress and federal regulatory agencies continually review banking laws, regulations and policies for possible changes. Changes to statutes, regulations or regulatory policies, including changes in interpretation or implementation of statutes, regulations or policies, could affect the Company in substantial and unpredictable ways. Such changes could subject the Company to additional costs, limit the types of financial services and products the Company may offer, and/or limit the pricing the Company may charge on certain banking services, among other things. Compliance personnel and resources may increase costs of operations and adversely impact earnings.

Failure to comply with laws, regulations or policies could result in sanctions by regulatory agencies, civil money penalties and/or reputation damage, which could have a material adverse effect on the Company’s business, financial condition and results of operations. While the Company has policies and procedures designed to prevent any such violations, there can be no assurance that such violations will not occur.

Changes in tax laws and regulations and differences in interpretation of tax laws and regulations may adversely impact the Company’s financial statements.

Federal, state, and local tax authorities may change tax laws and regulations, which could result in a decrease or increase to net deferred tax assets. In December 2017, the Company recognized a write-down of $4.0 million in net deferred tax assets in connection with the adoption of the Tax Cuts and Jobs Act of 2017 ("TCJA"). Federal, state, and local tax authorities may interpret tax laws and regulations differently and challenge tax positions that the Company has 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 results.

​

Goodwill from acquisitions could become impaired.

Applicable accounting standards require that the purchase method of accounting be used for all business combinations. Under purchase accounting, if the purchase price of an acquired company exceeds the fair value of the acquired company’s net assets, the excess is carried on the balance sheet as goodwill, by the acquirer. A significant decline in expected future cash flows, a continuing period of market disruption, market capitalization to book value deterioration, or slower growth rates may require the Company to record charges in the future related to the impairment of goodwill. If the Company concludes that a future write-down is necessary, the impact could have an adverse effect on financial condition and results of operations.

ITEM 3. LEGAL PROCEEDINGS

From time to time the Company may become involved in legal proceedings or may be subject to claims arising in the ordinary course of business. Although the results of litigation and claims cannot be predicted with certainty, the Company currently believes that the final outcome of these ordinary course matters will not have a material adverse effect on business, operating results, financial condition or cash flows. Regardless of the outcome, litigation can have an adverse impact on the Company because of defense and settlement costs, diversion of management resources and other factors.

(1) | Earning assets includes non-accruing loans and interest-bearing deposits with other banks. Securities are valued at amortized cost.

(2) | Net revenue is defined as net interest income plus non-interest income.

(3) | In December 2017, the Tax Cuts and Jobs Act of 2017 was enacted, and the Company recognized a $4.0 million write-down of its deferred tax assets and liabilities upon revaluation using the lower federal corporate income tax rate of 21.0%

(4) | All performance ratios are based on average balance sheet amounts, where applicable.

(5) | Fully taxable equivalent considers the impact of tax advantaged securities and loans.

(6) | Generally accepted accounting principles require that loans acquired in a business combination be recorded at fair value, whereas loans from business activities are recorded at cost. The fair value of loans acquired in a business combination includes expected loan losses, and there is no loan loss allowance recorded for these loans at the time of acquisition. Accordingly, the ratio of the loan loss allowance to total loans is reduced as a result of the existence of such loans, and this measure is not directly comparable to prior periods. Similarly, net loan charge-offs are normally reduced for loans acquired in a business combination since these loans are recorded net of expected loan losses. Therefore, the ratio of net loan charge-offs to average loans is reduced as a result of the existence of such loans, and this measure is not directly comparable to prior periods. Other institutions may have loans acquired in a business combination, and therefore there may be no direct comparability of these ratios between and among other institutions.

NON-GAAP FINANCIAL MEASURES

​

This document contains certain non-GAAP financial measures in addition to results presented in accordance with accounting principles generally accepted in the United States of America ("GAAP"). These non-GAAP measures are intended to provide the reader with additional supplemental perspectives on operating results, performance trends, and financial condition. Non-GAAP financial measures are not a substitute for GAAP measures; they should be read and used in conjunction with the Company’s GAAP financial information. A reconciliation of non-GAAP financial measures to GAAP measures is provided below. In all cases, it should be understood that non-GAAP measures do not depict amounts that accrue directly to the benefit of shareholders. An item that management excludes when computing non- GAAP adjusted earnings can be of substantial importance to the Company’s results for any particular quarter or year. The Company’s non-GAAP adjusted earnings information set forth is not necessarily comparable to non- GAAP information that may be presented by other companies. Each non-GAAP measure used by the Company in this report as supplemental financial data should be considered in conjunction with the Company’s GAAP financial information.

​

The Company utilizes the non-GAAP measure of adjusted earnings in evaluating operating trends, including components for adjusted revenue and expense. These measures exclude amounts that the Company views as unrelated to its normalized operations, including gains/losses on securities, premises, equipment and other real estate owned, acquisition costs, restructuring costs, legal settlements, and systems conversion costs. Non-GAAP adjustments are presented net of an adjustment for income tax expense.

​

The Company also calculates adjusted earnings per share based on its measure of adjusted earnings. The Company views these amounts as important to understanding its operating trends, particularly due to the impact of accounting standards related to acquisition activity. Analysts also rely on these measures in estimating and evaluating the Company’s performance. Management also believes that the computation of non-GAAP adjusted earnings and adjusted earnings per share may facilitate the comparison of the Company to other companies in the financial services industry. The Company also adjusts certain equity related measures to exclude intangible assets due to the importance of these measures to the investment community.

ITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

GENERAL

Management’s discussion and analysis is intended to assist in understanding the financial condition and results of operations of the Company. The information in this section should be read in conjunction with the Consolidated Financial Statements and accompanying Notes contained in this Form 10-K.

​

EXECUTIVE SUMMARY

​

The Company is focused on providing core banking products and services, including customized and innovative banking and lending solutions, designed to cater to the unique needs of its diverse communities, businesses and entrepreneurs through over 50 locations throughout Maine, New Hampshire and Vermont. Through over 500 dedicated professionals, the Company is committed to servicing and building enduring relationships by providing a higher standard of banking. The Company offers a variety of financial products and services designed around our target clients in order to serve all of their banking and financial needs. The Company continues to focus on three main initiatives designed to improve its franchise and profitability on an ongoing basis: attracting noninterest-bearing deposits and reducing our cost of deposits, optimizing the balance sheet to focus on higher-margin products while managing credit risk, and appropriately managing down expenses to the size and complexity of the business. Through these efforts, the Company continues to transform its franchise into a relationship-focused business bank within its footprint.

​

Financial Highlights

Bar Harbor Bankshares recorded 2020 net income of $33 million, or $2.18 per diluted share, compared to $23 million, or $1.45 per diluted share, in 2019. Adjusted income (non-GAAP measure) in 2020 was $35 million, or $2.26 per diluted share, and $30 million, or $1.91 per diluted share, for the same period of 2019. Non-recurring expenses in 2020 included swap termination costs and profitability initiative costs while 2019 included acquisition, conversion and balance sheet optimization costs.

​

Non-interest income reached record levels in 2020 driven by mortgage banking income, gains on sold securities and other fee income. The Company sold fixed rate residential mortgage production in the secondary market in lieu of taking interest rate and credit risk on the balance sheet, producing $7 million in fee revenue. The Company also took advantage of unrealized gains in the securities portfolio by selling certain investments for a net gain of $5 million. Customer service fees increased 12% on an expanded customer base from the prior year acquisition and a significant number of organic accounts opened throughout 2020. Additionally, the Company’s continued focus on commercial customers generated higher derivative and treasury income in 2020, and produced cross-sell opportunities within the retail and wealth management lines.

​

Wealth management remains a significant contributor to fee income in 2020; increasing 11% and serving as a foundation for deepening customer relationships with $2.3 billion in assets under management. During the year the Company consolidated leadership and combined operations onto a common platform in its wealth management business. This consolidation allowed for unified policies under one environment driven by best practices.

​

In 2020, the Company maintained its earning assets through commercial loan growth of $212 million or 17% through its strategy to grow variable rate loans. Non-maturity deposits grew $445 million or 25% through new accounts and the impacts of government stimulus. Excess liquidity generated from deposits was used to further delever the Company’s balance sheet by reducing wholesale funding $520 million or 49%. The reduction in wholesale funding consisted of repayments of $195 million in senior borrowings and maturities of $325 million in brokered deposits. These collective actions reduced the Company’s overall loan to deposit ratio to 88% at year-end 2020 compared to 98% in the prior year.

Table of Contents

The Company maintains a strong capital position; building tangible equity excluding security adjustments (non-GAAP measure) in 2020 to a higher level than before the branch acquisition in the fourth quarter of 2019. The Company furthered its return on capital programs in 2020 in the form of stock purchases and dividend payments. Stock repurchases during the year totaled 720 thousand shares at a cost of $13.9 million. An additional 61 thousand shares remain available to be repurchased before the plan expires in 2021. The Company distributed regular cash dividends on its common stock in the aggregate amount of $13 million representing a payout ratio of 40%.

​

Return on assets in 2020 was 0.88% compared to 0.62% in 2019, while adjusted return on assets (non-GAAP measure) was 0.92% in 2020 compared to 0.82% in 2019. In a similar trend, return on equity was 8.17% in 2020 from 5.82% in 2019 and adjusted return on equity (non-GAAP measure) was 8.48% in 2020 from 7.65% in 2019.

​

COVID-19 Pandemic

On March 13, 2020, a national emergency was announced related to the COVID-19 pandemic, which has since been extended. The COVID-19 pandemic has resulted in significant economic uncertainties that have had, and could continue to have, an adverse impact on the Company's operating income, financial condition and cash flows. The extent to which the COVID-19 pandemic will impact the Company's operations and financial results during 2021 cannot be reasonably or reliably estimated at this time. The Company has taken careful measures in an effort to ensure the safety of its employees and customers. That includes restricting nonessential employee travel, expanding remote access availability, distancing work stations, professional cleaning of its facilities, and signs and distancing reminders for customers in the banking centers. Further, the Company remains committed to providing uninterrupted and reliable banking service and has business continuity plans and protocols in place to ensure critical operations are able to continue without disruption. See further discussion in Item 1A – Risk Factors of this Form 10-K.

​

Credit Quality

The Company has experienced continuous positive trends in credit quality in 2020. Disciplined risk management has guided the Company through volatility created by the pandemic while also allowing the Company to focus on long-term goals. The Company had low levels of non-performing assets at 0.33% and past dues at 0.58% by year end 2020 including a 34% decrease in commercial loan delinquencies.

​

Starting in the second quarter 2020, the Company began stress testing the loan portfolio in addition to normal migration analysis. The stress testing of commercial loans included the most affected industries by COVID-19 within the Company’s footprint, specifically hospitality. However, the Company’s customers in the hospitality industry benefited from a better than expected summer tourism season for Northern New England. Testing results throughout the year affirm the Company’s risk-based credit philosophy with no significant risk-rating downgrades or changes to reserves.

​

Paycheck Protection Program Loans

In response to the COVID-19 pandemic the CARES Act went into law on March 27, 2020, which provides assistance for American workers, families and small businesses. The Paycheck Protection Program ("PPP"), established by the CARES Act and implemented by the Small Business Administration ("SBA") provides small businesses with funds to pay payroll costs, pay interest on mortgages, rent, and utilities and are 100% guaranteed by the SBA. PPP loans have a two year term, carry an interest rate at 1% and earn an amortizing SBA fee between 1 to 5% depending of the size of the loan. These loans are recorded on the Company’s balance sheet as commercial and industrial loans. In 2020, the Company obtained SBA approvals on approximately $132 million with $5 million of fees on 1,900 PPP loans. As of December 31, 2020, the Company had an outstanding balance of loans totaling $54 million and $1 million of deferred fees. The Company expects the majority of remaining forgiveness to occur by the end of the second quarter 2021.

​

On December 27, 2020, the Consolidated Appropriations Act of 2021 ("CAA") was signed into law, which extended certain provisions of the CARES Act and provided additional funding. The CAA extended the PPP application period to March 31, 2021 and permits eligible companies to obtain a second PPP loan with a maximum amount of $2.0 million. This second round of loans carry similar terms and conditions as the first round and lenders are eligible for the same range of SBA processing fees. The Company plans to continue the PPP program into the first quarter of 2021.

Loan Modifications

Also in response to the COVID-19 pandemic the Company has supported its customers through loan deferrals. Under the CARES Act and the CAA Act, banks may deem that loan modifications do not result in troubled debt restructurings if they are (1) related to COVID-19; (2) executed on a loan that was not more than 30 days past due as of December 31, 2019; and (3) executed between March 1, 2020, and the earlier of (A) 60 days after the date of termination of the COVID-19 national emergency declaration by the President of the United States or (B) January 1, 2022. Additionally, other short-term modifications made on a good faith basis in response to COVID-19 to borrowers who were current prior to any relief are not troubled debt restructurings under ASC Subtopic 310-40 and federal banking agencies' interagency guidance.

​

Over the course of the year the Company modified over 800 loans totaling about $400 million, which were mostly temporary principal deferrals with normal interest accruals. The loans modified under deferment plans are still accruing interest and all contractual principal and interest is expected to be collected. As of December 31, 2020, the Company had 69 COVID-19 modified loans totaling $69 million.

​

CECL

In 2020, the Company implemented the CECL methodology and ran it concurrently with the historical incurred method. Under a provision provided by the CARES Act of 2020, the Company elected to delay the adoption of the CECL standard. On December 27, 2020, the Consolidated Appropriations Act, 2021 was signed into law. This law extended relief for troubled debt restructurings and provided for further delay of the current expected credit losses adoption under the CARES Act to January 1, 2022, with early adoption permitted. The Company elected to remain on the incurred loan loss methodology for 2020 and will adopt the CECL standard during the first quarter of 2021, effective January 1, 2021. Had the Company adopted CECL at year end 2020, the loan loss reserve as a percentage of total loans would have been 95 basis points compared to 74 basis points reported under the incurred loss model. The 95 basis points may change in the first quarter of 2021 based primarily on any changes in economic forecasts.

​

COMPARISON OF FINANCIAL CONDITION AT DECEMBER 31, 2020 AND 2019

Summary

The Company offers a competitive mix of loan and deposit products to serve the retail and commercial markets in its footprint. Loans and investment securities are the Company’s primary earning assets and net interest income from these products is its primary revenue source. Funding of the Company’s earning assets is achieved through its management of liabilities, attempting to provide stable and flexible sources of funding within well-defined credit, investment, interest rate and liquidity guidelines. The Company’s objective is to optimize its balance sheet position and enhance profitability with controlled risk. The Company maintains adequate liquidity under both prevailing and forecasted economic conditions achieved primarily through an appropriate mix of deposits and borrowed funds. Total assets were $3.7 billion in 2020, remaining steady with 2019.

Cash and Cash Equivalents

The Company maintains cash vaults and teller drawers to service customers along with transactional cash accounts to service the needs of the Company and its subsidiaries that are non-interest bearing. Interest-bearing deposits are maintained with other banks such as the Federal Reserve Bank, Federal Home Loan Bank, and other correspondent banks. These accounts are used to fund reserve requirements, debt service on senior borrowings, and serve as collateral for correspondent bank relationships. In addition, these accounts hold any excess liquidity used to fund higher earning assets. The Company continuously monitors cash levels to ensure compliance with applicable regulatory requirements, including liquidity and reserve requirements.

​

Total cash and cash equivalents at December 31, 2020 were $226 million, compared to $57 million at December 31, 2019. The increase in cash and cash equivalent balances of $169 million between periods was driven by unanticipated extensive growth in non-maturity deposits from new accounts and government stimulus outpacing the growth in other earning assets. The biggest portion of the growth is in Federal Reserve balances reflected in interest bearing deposits with other banks that grew by $168 million. The average earning yield on interest bearing deposits in 2020 is 0.15% compared to 0.96% in 2021, which reduces net interest margin 16 basis points and one basis point, respectively from excess liquidity.

Securities

The Company maintains a relatively high quality and liquid securities portfolio primarily consisting of US Government-sponsored enterprises and US Government agency mortgage-backed securities, obligations of states and political subdivisions, corporate bonds, and to a much lesser extent other asset backed securities and non-agency mortgage securities. The securities portfolio is managed in accordance with achieving the Company’s asset-liability objectives which includes managing liquidity, funding, capital, and structural interest rate risks. Investments are evaluated within this framework and policy guidelines which have been established by the Company’s Board of Directors. The Company continuously evaluates and monitors the securities portfolio tied to credit, liquidity, duration, suitability and other metrics. Included in the Company’s total securities is FHLB stock which is a non-marketable equity security and, therefore, is reported at cost.

Securities in 2020 decreased $85 million as the Company focused on meeting overall asset-liability objectives when interest rates increase from their current low levels. Securities activity during the year included purchases of $216 million offset by maturities, calls and pay downs of $152 million and sales of $153 million. The proceeds from sales and amortizing securities supported asset-liability objectives to increase liquidity, reduce prepayment and reinvestment risk, and improve risk adjusted returns.

The Company monitors our securities portfolio to ensure adequate credit support. As of December 31, 2020, the Company has identified no credit impairment. There is no current intent to sell securities with a fair value below amortized cost at December 31, 2020, and it is more likely than not that the Company will not be required to sell such securities prior to the recovery of their amortized cost basis. We consider the lowest credit rating and industrial analysis for identification of potential credit impairment.

In 2020, the Company sold securities of $153 million with a net gain of $5 million. The sales strategy took advantage of favorable market conditions with attractive prices allowing the Company to sell securities projected to have sub-optimal returns and lower liquidity profiles at sizable gains. The Company was then able to repurchase more liquid securities with reduced prepayment risk and improved risk adjusted returns. The execution of the fourth quarter trades led to slight increase in profitability metrics and availability to pledge additional securities with the FHLB. Although the sales generating realized gains the Company still improved December 31, 2020 unrealized gains, net of tax to $10 million compared to $6 million at December 31, 2019.

The weighted average yield on the Company’s securities portfolio was 2.96% in 2020 compared to 3.42% in the prior year. The weighted average life of the securities portfolio at December 31, 2020 was estimated to be 4.8 years, with a duration of approximately 4.3 years. These metrics compare with an estimated weighted average life of 5.0 years, with a duration of approximately 3.6 years for the portfolio at December 31, 2019.

Loans Held For Sale

Held for sale loans increased by $18 million to $24 million at December 31, 2020 from $6 million at December 31, 2019 as a result of strong mortgage refinancing demand in response to the low interest rate environment. This asset category is subject to a high degree of variability depending on, among other things, recent mortgage loan rates and the timing of loan sales into the secondary market. In 2020, the Company’s strategy was to sell most of its residential mortgage originations on the secondary market. Proceeds from sales totaled $223 million in 2020, $63 million in 2019 and $58 million in 2018.

​

Loans

The Company’s loan portfolio is comprised of the following segments: commercial real estate, commercial and industrial, residential real estate, and consumer loans. Commercial real estate loans include multi-family, commercial construction and land development, and other commercial real estate classes. Commercial and industrial loans include loans to commercial businesses and tax exempt entities including PPP loans to small businesses. Residential real estate loans consist of mortgages for 1-4 family housing. Consumer loans include home equity loans, lines of credit and auto and other installment lending.

During 2020 total loans decreased $72 million to $2.6 billion. Given the current economic environment, the Company selectively grew total commercial loans to $1.5 billion or at a pace of 17%. Commercial and industrial loans grew 18%

40

Table of Contents

during the year, and 2% excluding PPP loans as the Company closely monitored risk associated with growth prospects in the portfolio. Commercial loan growth was offset by a decline in residential loan balances of $221 million or 20% as the Company strategically moved a majority of production to the secondary market platform to generate fee income. Residential loan production was led by refinancing activity given the lower interest rate environment and originations totaled $246 million in 2020 compared to $67 million in 2019.

The Company offered PPP loans in an effort to assist its business partners and communities. The Company will continue the program with the second round of PPP loans authorized by the new stimulus bill in 2021. The Company originated over 1,900 first-round PPP loans totaling $132 million, of which many have been submitted for forgiveness by the SBA. The remaining first round PPP loans total $54 million with an associated $1 million of deferred fees not yet recognized in income and are expected to be forgiven by the end of the second quarter 2021. The Company also offered borrowers COVID-19 loan modifications consisting mostly of temporary deferrals with normal interest accruals. The modifications totaled over 800 loans or about $400 million over the course of the year.

The Company’s loan portfolio remains diverse among many different industries over several geographies. However, commercial loans represent 60% of the total portfolio and typically involve larger balances and gives rise to concentration risk.

​

All commercial loans are assigned Standard Industrial Classification codes, North American Industry Classification System codes, and state and county codes. The following table summarizes the major industries of the Company’s commercial loan portfolio as of December 31, 2020:

(in thousands) |  | Amount |  | Percent of Portfolio

​

The largest concentrations in the commercial loan portfolio are commercial real estate and hospitality representing 42% and 18%, respectively. Concentrations are managed through a serious of loan policy limits and stringent underwriting requirements to minimize exposures. Loan policy limits are based on Tier 1 Risk Based Capital (TRBC) as computed in quarterly regulatory reporting. At December 31, 2020, none of these TRBC thresholds were exceeded. In regard to stringent underwriting requirements the Company has established minimum thresholds for loan to value ratios, debt service coverage rations, and requirements for personal guarantees. The Company also performs a borrower revenue/margin sensitively analysis on current financials to determine the impact of decreases in borrower revenues on cash flow and ability to cover debt service.

Allowance for loan losses

The determination of the allowance for loan losses is a critical accounting estimate. The Company’s methodologies for determining the loan loss allowance are discussed in Note 1 - Summary of Significant Accounting Policies of the Consolidated Financial Statements.

The year-end 2020 allowance for loan losses increased to $19 million from $15 million in 2019 largely due to commercial loan growth and increased qualitative economic factors associated with the pandemic. The allowance for loan losses to total loans ratio expanded at year-end 2020 to 0.74% from 0.58% at year-end 2019. As noted above the Company has adopted CECL as of January 1, 2021 which will result in a higher allowance coverage ratio. Non-accruing loans in 2020 decreased primarily due to $2 million in commercial and residential payoffs during the fourth quarter.

Due to the impacts of the pandemic the Company began and expanded quarterly stress testing of its commercial loan portfolio throughout 2020. Fourth quarter testing covered 54% of the portfolio including the top 50 relationships, all criticized loans greater than $1.0 million, hospitality loans greater than $250 thousand, all loans over $150 thousand with a pandemic modification and any seasonal payment, restaurant, or 2021 maturing term loans greater than $500 thousand. Results of the stress testing led to no significant downgrades or changes to reserves.

Other Assets

The Company identifies on its balance sheet premises and equipment, other real estate owned, goodwill, other intangible assets, bank-owned life insurance, net deferred tax assets and other assets consisting of derivative fair values, right of use asset, community investments, and receivables. These collective assets totaled $333 million at the end of 2020 compared to $303 million as of December 31, 2019. The increase is primarily from the $26 million gross up of the fair value in customer loan derivatives and $3 million in community limited partnership investments made during 2020 reflected in the cash flow from investing activities. Community limited partnership investments provide affordable loans or equity funding typically for multifamily or residential real estate in qualified community reinvestment areas, some of which may involve low income housing tax credits. Partnerships can also include loans for commercial purposes used in economic development in qualified community reinvestment areas.

Deposits

The Company views its customer relationships as key to building its core funding platform. The Company offers competitive deposit products with local convenience including accounts with cash-back rewards. Historically, the Company’s deposit market experiences some seasonality, with lower deposits in the winter and spring months and higher deposits in the summer and autumn months.

Total deposits increased $210 million to $2.9 billion in 2020 from $2.7 billion in 2019. Non-maturity deposits grew by $445 million or 25%, with the Company’s retail team opening 13,250 new accounts for the year and impacts of government stimulus. Time deposits decreased $235 million given a $325 million reduction in brokered deposits offset by $90 million of growth in customer time deposits. Lower interest rates and the divergence in brokered deposit spreads provided an opportunity to lock into favorable rates with longer maturities in early 2020. The Company improved its loan-to-deposit ratio to 88% at year-end from 98% at the end of 2019 primarily as a result of deposit growth and residential loan sales.

Borrowings

Borrowed funds provide a means to help manage balance sheet interest rate risk, given the Company’s ability to select desired amounts, terms and maturities on a daily basis. Senior borrowings principally consist of advances from the FHLB and, to a lesser extent, securities sold under agreements to repurchase. Advances from the FHLB are secured by stock in the FHLB, investment securities, certain commercial real estate loans, and blanket liens on qualifying mortgage loans and home equity loans. Subordinated borrowings consist of notes issued to accredited investors and provides a stable source of funding and capital to the Company. Contingency lines of credit are also maintained with the Federal Reserve Bank of Boston and a correspondent bank.

At December 31, 2020 total borrowings were $336 million with a weighted average rate of 1.41% compared to $531 million with a weighted average rate of 2.11% at year-end 2019. Prior to the pandemic the Company’s borrowings strategy centered around managing seasonal drops in core deposit funding while neutralizing fixed rate asset growth which involved locking into favorable rates on longer maturities. As a result 2020 long-term borrowings increased by $59 million with a

42

Table of Contents

weighted average rate of 2.37% at December 31, 2020 compared to 2.87% at December 31, 2019. Following the onset of the pandemic the Company changed strategy to leverage funds from strong core deposit growth to offset maturing short-term borrowings. Overall borrowings decreased $195 million or 37% from year-end 2019 primarily as excess liquidity was used to pay down borrowings. Short-term borrowings were reduced during the year by $254 million to $93 million with a weighted average rate of 0.44% compared to 1.73% at December 31, 2019.

​

Derivative Financial Instruments and Hedging Activities

The Company utilizes derivative instruments to minimize fluctuations in earnings and cash flows caused by interest rate volatility. The notional balance of derivative financial instruments increased to $877 million at the end of 2020 from $580 million at year-end 2019. The increase is primarily due to $300 million in customer loan derivatives sold on commercial loans with matching hedges using a national bank counterparty. The net fair value of total derivatives was a net asset of $52 thousand at the end of 2020 compared to a net liability of $743 thousand at year-end 2019.

Cash flow hedges reflected a new $25 million notional amount hedge on wholesale funding in April 2020. Based on direct and indirect events resulting from COVID-19 pandemic, the Company determined that $50 million of wholesale funding was no longer necessary. A hedge the Company placed in March 2019 with a $50 million notional amount and fixed rate of 2.46% was terminated in October 2020. As a result of the termination a $4 million loss recognized in acquisition, conversion, and other expenses as a result of the reclassification of the unrealized loss from other comprehensive income.

Stockholders’ Equity

Total equity was $411 million at year-end 2020, compared with $396 million at year-end 2019. The Company’s book value per share increased $2.10 to $27.58 from year-end 2019. The increase was primarily due to strong net income of $33 million and a $7 million improvement in other comprehensive income offset by $13 million in dividends and $14 million in stock repurchases. The Company evaluates changes in tangible book value, a non-GAAP financial measure that is a commonly used valuation metric in the investment community, which parallels some regulatory capital measures. Tangible book value per share increased to $19.05 per share at year-end 2020 up from $17.30 per share at year-end 2019.

During 2020 and 2019, the Company declared and distributed regular cash dividends on its common stock in the aggregate amount of $13 million for both periods. The Company’s 2020 dividend payout ratio amounted to 40%, compared with 59% in 2019. Total cash dividends paid in 2020 was $0.88 per common share of stock, compared with $0.86 in 2019.

On March 12, 2020, the Company’s Board of Directors authorized a share repurchase plan (the “Plan”). Under the terms of the Plan, the Company is authorized to repurchase up to 5% of its outstanding common stock, representing approximately 781,000 shares. The Plan is authorized for twelve months expiring on March 20, 2021 and authorized based on the strength of the Company’s balance sheet and capital position, and the Company’s belief in the intrinsic value of the Company’s common stock. Given the current market for bank stock prices, the Company believes this program is another tool to enhance long-term shareholder value. As of December 31, 2020, the Company has purchased 720,043 shares.

The Company and the Bank remained well-capitalized under regulatory guidelines at period end as further described in Note 13 - Shareholders’ Equity and Earnings Per Common Share on the Consolidated Financial Statements.

COMPARISON OF OPERATING RESULTS FOR THE YEARS ENDED DECEMBER 31, 2020 AND 2019

Summary

Net income in 2020 was $33 million compared to $23 million in 2019. The non-GAAP measure of adjusted earnings in 2020 was $35 million compared to $30 million in 2019 and included acquisition, conversion and other expense charges of $6 million and $8 million, respectively. Net income and adjusted earnings benefited from an expanded net interest margin and higher non-interest income.

Net Interest Income

Net interest income is the principal component of the Company’s income stream and represents the difference or spread between interest generated from earning assets and the interest expense paid on deposits and borrowed funds. Fluctuations

43

Table of Contents

in market interest rates as well as volume and mix changes in earning assets and interest-bearing liabilities can materially impact net interest income.

Net interest income for 2020 was $99 million compared with $90 million in 2019 primarily due to a lower cost of funds resulting from increased liquidity from growth in non-maturity deposits. The net interest margin expanded to 2.97% in 2020 compared to 2.77% in the prior year. Purchase loan accretion contributed 11 and 10 basis points to the margin in 2020 and 2019, respectively. Cost of deposits and borrowings also benefited from the Federal Reserve rate cuts in 2020 and changes in other key indexes in response to the pandemic. In total cost of funds decreased 65 basis points to 0.96% compared to 1.61% in 2019 due to the shift in funding sources to core deposits. Total interest-bearing deposit rates improved to 0.78% compared to 1.27% in 2019 from growth in core deposits and reductions in time deposits during 2020. Borrowing costs improved to 1.75% from 2.61% in 2019, on reduced borrowing levels and interest rates.

​

The yield on earning assets was 3.87% compared to 4.14% in 2019 reflecting loan originations and repricing of variable rate products in a lower interest rate environment. Both securities yields and loan yields dropped 22 basis points to 3.20% and 4.16%, respectively for 2020. The 2020 adjusted net interest margin (non-GAAP measure), which excludes PPP loans was 2.93% compared to 2.77% for 2019, which included a drag of 16 basis points and one basis point, respectively from excess liquidity reflected in interest-bearing deposits with other banks.

​

Loan Loss Provision

The level of the allowance is a critical accounting estimate, which is subject to uncertainty. The provision for loan losses is a charge to earnings in an amount sufficient to maintain the allowance for loan losses at a level deemed adequate by the Company. The provision was $6 million in 2020 compared to $2 million in 2019. Credit quality metrics improved with decreases in non-accruing and past due loans. Overall credit quality remains strong, the increase in the provision is indicative of commercial loan growth and higher economic adjustments reflecting elevated risk from COVID-19.

Non-Interest Income

Non-interest income are fees that are fundamental to the Company’s profitability through revenue diversification in the forms of trust and treasury management services, customer service fees, customer loan derivatives, and secondary market mortgage sales.

Non-interest income in 2020 increased to $43 million from $29 million in 2019 driven primarily by increases in mortgage banking income and gains on sold securities. The $5 million increase in mortgage banking income is associated with secondary market sales of $223 million compared to $63 million in 2019. The Company took advantage of unrealized gains in the securities portfolio in 2020 by selling certain investments for a net gain of $5 million. Customer loan derivative income also contributed to non-interest income as demand for these products remained strong within the commercial loan pipeline throughout the year. Customer services fees increased by over $1 million to $11 million resulting from expanded operations into Central Maine offset by impacts of the pandemic on these services. Wealth management income grew over $1 million to $13 million in 2020. The increase reflects a full year of having assets under management acquired in the fourth quarter of 2019 totaling $218 million.

​

Non-Interest Expense

Non-interest expense was $95 million in 2020 compared to $90 million in 2019. The increase is primarily a result of a $4 million higher salary and benefit expense due to the expanded branch model and wealth management business. Salary and benefit expense was also impacted by larger accruals for incentives on improved performance metrics and post-retirement plan costs based on lower discount rates. Additionally, occupancy and equipment costs increased by $3 million based on the expanded footprint in central Maine. Operating expenses remained controlled as the efficiency ratio (non-GAAP) improved to 61.71% in 2020 from 64.95% in 2019. Non-recurring expenses in 2020 primarily consisted of a $4 million loss on termination of a $50.0 million swap on wholesale borrowings and a $1 million loss on extinguishment of debt on longer-term and higher cost FHLB borrowings. The remaining represents costs for profitability initiatives including trust system conversion and consolidation. Non-recurring expenses in 2019 included a $3 million loss on interest rate cap terminations, $3 million related to the branch acquisition, and $2 million related to branch optimization and other strategic initiatives.

Income Tax Expense

The amount of federal and state income tax expense is influenced by the amount of pre-tax income, the amount of tax-exempt income and the amount of other nondeductible expenses. Income tax expense was $8 million for the year ended December 31, 2020, compared with $4 million for the year ended December 31, 2019. The effective tax rate increased to 20.2% in 2020 from 15.7% in 2019, reflecting the higher level of taxable income and lower level of non-tax advantaged income in 2020. This reflects higher income in 2020 from the Company’s expanded customer base in the state of Maine along with higher core deposits that carry a lower cost of funds.

COMPARISON OF OPERATING RESULTS FOR THE YEARS ENDED DECEMBER 31, 2019 AND 2018

Summary

Net income in 2019 was $23 million compared to $33 million in 2018 and included acquisition, restructuring and other expense charges of $8 million and $2 million, respectively. The non-GAAP measure of adjusted earnings in 2019 was $30 million compared to $35 million in 2018. Net income and adjusted earnings in 2019 benefited from expanded yields on earning assets and non-interest income growth, offset by higher cost of funds. Results for 2019 include operations from the branch acquisition as of the October 25, 2019 effective date.

Net Interest Income

Net interest income for 2019 was $90 million compared with $91 million in 2018. Interest income was $135 million, up 6% from $127 million in 2018 as average earning assets grew $70 million. The net interest margin was 2.78% in 2019 compared to 2.87% in the prior year. Purchase loan accretion contributed 10 and 11 basis points to the margin in 2019 and 2018, respectively. Yields expanded across all loan categories as variable rate products in the first half of 2019 repriced to higher rates driven by the 2018 short-term hikes. The 2019 yield on securities improved by 19 basis points reflecting the benefit of portfolio remix strategies and associated security sales in the second half of 2019. These improvements in interest from earning assets were offset by a higher cost of interest bearing liabilities, especially in the first half of 2019, which was also driven by short-term rate hikes in late 2018. While the cost of interest bearing liabilities increased 30 basis points to 1.61% on a year-over-year basis, the same costs improved to 1.42% in the fourth quarter due to executing deleveraging strategies associated with the branch acquisition and securities sales.

Loan Loss Provision

The level of the allowance is a critical accounting estimate, which is subject to uncertainty. The provision for loan losses is a charge to earnings in an amount sufficient to maintain the allowance for loan losses at a level deemed adequate by the Company. The provision was $2 million in 2019 compared to $3 million in 2018. The decrease is primarily due to lower charge-offs in 2019 as compared to prior year reflecting continued improvement in credit quality.

Non-Interest Income

Non-interest income for 2019 increased to $29 million from $28 million in 2018 driven primarily by customer loan derivative income, which increased to $2 million in 2019 compared to $860 thousand in 2018. The increase in these fees is attributable to the Company’s continued focus on the complexity of the financial needs of its customers and related commercial loan growth in 2019. Customer service fees also contributed to the overall increase in non-interest income growing by $589 thousand in 2019. The increase is due to higher transaction volume principally from the deposit base obtained through the branch acquisition. Trust and investment management fee income in 2019 was relatively flat with 2018. However, assets under management increased to $2.0 billion in 2019 compared to $1.7 billion in 2018 primarily due wealth management accounts that were obtained through the branch acquisition.

Non-Interest Expense

Non-interest expense was $90 million in 2019 compared to $76 million in 2018. The increase in 2019 includes $3 million related to the branch acquisition, a $3 million reclassification of losses on the interest rate cap derivative from other comprehensive income and $3 million related to branch optimization and other strategic review expenses. Salary and employee benefits expenses increased by $4 million due to postretirement benefit revaluations on lower discount rates and an increase in full time equivalent employees (“FTEs”). FTEs totaled 531 at the end of 2019 compared with 445 at the end of 2018, which includes employees from the branch acquisition.

45

Table of Contents

Income Tax Expense

The effective tax rate decreased to 15.7% in 2019 from 18.7% in 2018 due to a higher proportion of tax-advantaged income to taxable income, which was driven by overall lower net income in 2019 as compared to 2018.

The Alternative Reference Rates Committee continues its work in finding suitable replacements for LIBOR. It is expected that a transition away from the widespread use of LIBOR to alternative reference rates and other potential interest rate benchmark reforms will occur beginning potentially in 2022. Although the full impact of such reforms and actions, together with any transition away from LIBOR remains unclear, the Company is preparing to transition from the LIBOR to an alternative reference rate.

​

The Company’s transition plan includes a number of key steps, including engagement with central bank and industry working groups and regulators, active client engagement, internal operational readiness, and risk management, among other things, to promote the transition to alternative reference rates. The Company is identifying on-balance sheet and off-balance sheet references to LIBOR, determining appropriate language to replace the LIBOR index language, and determining disclosures necessary for customers, with appropriate procedures and schedules to complete the LIBOR transition.

​

However, there is a number of unknown factors regarding the transition from LIBOR or interest rate benchmark reforms that could impact the Company’s business, including, for example, the pace of the transition to replacement or reformed rates, the specific terms and parameters for and market acceptance of the alternative reference rates, prices of and the liquidity of trading markets for products based on the alternative reference rates, and ability to transition to and develop appropriate systems and analytics for one or more alternative reference rates.

​

For a further discussion of the various risks the Company faces in connection with the expected replacement of LIBOR and reform of interest rate benchmarks on operations, see Item 1A of this Form 10K – “Risk Factors,” paragraph for “Reforms to London Interbank Offered Rate ("LIBOR") and other indices, and related uncertainty, may adversely affect our business, financial condition or results of operations.”

LIQUIDITY AND CASH FLOWS

Liquidity is measured by the Company’s ability to meet short-term cash needs at a reasonable cost or minimal loss. The Company seeks to obtain favorable sources of liabilities and to maintain prudent levels of liquid assets in order to satisfy varied liquidity demands. Besides serving as a funding source for maturing obligations, liquidity provides flexibility in responding to customer initiated needs. Many factors affect the Company’s ability to meet liquidity needs, including variations in the markets served by its network of offices, its mix of assets and liabilities, reputation and credit standing in the marketplace, and general economic conditions.

The Bank actively manages its liquidity position through target ratios established under its Asset Liability Management Policy. Continual monitoring of these ratios, by using historical data and through forecasts under multiple rate and stress scenarios, allows the Bank to employ strategies necessary to maintain adequate liquidity. The Bank’s policy is to maintain a liquidity position of at least 4% of total assets. A portion of the Bank’s deposit base has been historically seasonal in nature, with balances typically declining in the winter months through late spring, during which period the Bank’s liquidity position tightens.

The Bank maintains a liquidity contingency plan approved by the Bank’s Board of Directors. This plan addresses the steps that would be taken in the event of a liquidity crisis, and identifies other sources of liquidity available to the Company. Company management believes that the level of liquidity is sufficient to meet current and future funding requirements. However, changes in economic conditions, including consumer savings habits and availability or access to the brokered deposit market could potentially have a significant impact on the Company’s liquidity position.

The Company believes the existing cash and cash equivalents (including an interest-bearing deposit at the FRB Boston), securities available for sale and cash flows from operating activities will be sufficient to meet anticipated cash needs for at least the next twelve months. Future working capital needs will depend on many factors, including the rate of business and revenue growth. To the extent cash and cash equivalents, securities available for sale and cash flows from operating activities are insufficient to fund future activities, the Company may need to raise additional funds through debt arrangements or public or private debt or equity financings. The Company also may need to raise additional funds in the event it is determined in the future to effect one or more acquisitions of banks or businesses. If additional funding is required, the Company may not be able to obtain debt arrangements or to effect an equity or debt financing on terms acceptable to the Company or at all.

Capital Resources

Consistent with its long-term goal of operating a sound and profitable organization, at December 31, 2020, the Company maintained its strong capital position and continued to be a “well-capitalized” financial institution according to applicable regulatory standards. Management believes this to be vital in promoting depositor and investor confidence and providing a solid foundation for future growth.

The Company’s liquidity position remains strong. During the quarter we initiated pandemic-specific liquidity stress tests to analyze potential impacts from payment deferrals, unanticipated use of committed lines of credit, as well as the possibility of required servicer advances on sold loans. At December 31, 2020, available same-day liquidity totaled approximately $1.1 billion, including cash, borrowing capacity at FHLB and the Federal Reserve Discount Window and various lines of credit. Additional sources of liquidity include cash flows from operations, wholesale deposits, cash flow from the Company's amortizing securities and loan portfolios. The Company had unused borrowing capacity at the FHLB of $511.9 million, unused borrowing capacity at the Federal Reserve of $81.1 million and unused lines of credit totaling $71.9 million, in addition to over $200.0 million in unencumbered, liquid investment portfolio assets. The Company has also utilized the Federal Reserve's Paycheck Protection Program Liquidity Facility to provide liquidity to fund PPP loans.

​

Contractual Obligations

The Company is a party to certain contractual obligations under which it is obligated to make future payments. These principally include borrowings from the FHLB, consisting of short-term and long-term fixed rate borrowings, and collateralized by all stock in the FHLB; a blanket lien on qualified collateral consisting primarily of loans with first and second mortgages secured by one-to-four family properties; and certain pledged investment securities. The Company has an obligation to repay all borrowings from the FHLB.

In the normal course of conducting its banking and financial services business, and in connection with providing products and services to its customers, the Company has entered into a variety of traditional third-party contracts for support services. Examples of such contractual agreements include, but are not limited to: services providing core banking systems, ATM and debit card processing, trust services software, accounting software and the leasing of T-1 telecommunication lines and other technology infrastructure supporting the Company’s network.

The following table summarizes the Company’s contractual obligations at December 31, 2020:

EFFECTS OF INFLATION

Inflation and changing prices have not had a material effect on the Company’s business, and the Company does not expect that they will materially affect the business in the foreseeable future. Any impact of inflation on cost of revenue and

operating expenses, especially employee compensation costs, may not be readily recoverable in the price of the Company product offerings.

OFF-BALANCE SHEET ARRANGEMENTS

The Company is a party to certain off-balance sheet arrangements that have or are reasonably likely to have a current or future effect on the Company’s financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources that may be material to investors.

At December 31, 2020 and 2019, the Company’s off-balance sheet arrangements were limited to customer obligations, in the normal course of business to meet customer’s financing needs. These financial arrangements include commitments to extend credit, unused or unadvanced loan funds, and letters of credit. The Company uses the same lending policies and procedures to make such commitments as it uses for other lending products. Customers’ creditworthiness is evaluated on a case-by-case basis.

Commitments to originate loans, including unused or unadvanced loan funds, are agreements to lend to a customer provided there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require the customer to pay a fee. Since many of the commitments are expected to expire without being fully drawn upon, the total commitment amounts do not necessarily represent future cash requirements.

Standby letters of credit are conditional commitments issued by the Company to guarantee the performance of a customer to a third party. Standby letters of credit generally become payable upon the failure of the customer to perform according to the terms of the underlying contract with the third party, while commercial letters of credit are issued specifically to facilitate commerce and typically result in the commitment being drawn on when the underlying transaction is consummated between the customer and a third party. The contractual amount of these letters of credit represents the maximum potential future payments guaranteed by the Company. Typically these letters of credit expire if unused; therefore the total amounts do not necessarily represent future cash requirements. For further detail see Note 12 - Other Commitments, Contingencies and Off-Balance Sheet Activities of the Consolidated Financial Statements.

IMPACT OF NEW ACCOUNTING PRONOUNCEMENTS

Please refer to the notes on Recently Adopted Accounting Principles and Future Application of Accounting Pronouncements in Note 1 - Summary of Significant Accounting Policies of the Consolidated Financial Statements.

APPLICATION OF CRITICAL ACCOUNTING POLICIES AND ACCOUNTING ESTIMATES, AND RECENT ACCOUNTING PRONOUNCEMENTS

The Company’s significant accounting policies are described in Note 1 - Summary of Significant Accounting Policies of the Consolidated Financial Statements in this Annual Report on Form 10-K. The preparation of the consolidated financial statements in accordance with GAAP and practices generally applicable to the financial services industry requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, and expenses, and to disclose contingent assets and liabilities. Actual results could differ from those estimates.

Management has identified the Company’s most critical accounting policies as related to:

| ● | Allowance for Loan Losses

| ● | Acquired Loans

| ● | Income Taxes

| ● | Goodwill and Identifiable Intangible Assets

| ● | Determination of Other-Than-Temporary Impairment of Securities

| ● | Fair Value of Financial Instruments

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Market Risk

Market risk is the risk of loss in a financial instrument arising from adverse changes in market rates/prices, such as interest rates, foreign currency exchange rates, commodity prices and equity prices. Interest rate risk is the most significant market risk affecting the Company. Other types of market risk do not arise in the normal course of the Company’s business activities.

​

The responsibility for interest rate risk management oversight is the function of the Bank’s Asset and Liability Committee (“ALCO”), chaired by the Chief Financial Officer and composed of various members of senior management. ALCO meets regularly to review balance sheet structure, formulate strategies in light of current and expected economic conditions, adjust product prices as necessary, implement policy, monitor liquidity, and review performance against guidelines established to control exposure to the various types of inherent risk.

​

Interest Rate Risk: Interest rate risk can be defined as an exposure to movement in interest rates that could have an adverse impact on the Bank's net interest income. Interest rate risk arises from the imbalance in the re-pricing, maturity and/or cash flow characteristics of assets and liabilities. Management's objectives are to measure, monitor and develop strategies in response to the interest rate risk profile inherent in the Bank's balance sheet. The objectives in managing the Bank's balance sheet are to preserve the sensitivity of net interest income to actual or potential changes in interest rates, and to enhance profitability through strategies that promote sufficient reward for understood and controlled risk.

​

The Bank's interest rate risk measurement and management techniques incorporate the re-pricing and cash flow attributes of balance sheet and off-balance sheet instruments as each relate to current and potential changes in interest rates. The level of interest rate risk, measured in terms of the potential future effect on net interest income, is determined through the use of modeling and other techniques under multiple interest rate scenarios. Interest rate risk is evaluated in depth on a quarterly basis and reviewed by ALCO and the Company’s Board of Directors.

​

The Bank's Asset Liability Management Policy, approved annually by the Bank’s Board of Directors, establishes interest rate risk limits in terms of variability of net interest income under rising, flat, and decreasing rate scenarios. It is the role of the ALCO to evaluate the overall risk profile and to determine actions to maintain and achieve a posture consistent with policy guidelines.

​

Interest Rate Sensitivity Modeling: The Bank utilizes an interest rate risk model widely recognized in the financial industry to monitor and measure interest rate risk. The model simulates the behavior of interest income and expense for all balance sheet and off-balance sheet instruments, under different interest rate scenarios together with a dynamic future balance sheet. Interest rate risk is measured in terms of potential changes in net interest income based upon shifts in the yield curve.

​

The interest rate risk sensitivity model requires that assets and liabilities be broken down into components as to fixed, variable, and adjustable interest rates, as well as other homogeneous groupings, which are segregated as to maturity and type of instrument. The model includes assumptions about how the balance sheet is likely to evolve through time and in different interest rate environments. The model uses contractual re-pricing dates for variable products, contractual maturities for fixed rate products, and product-specific assumptions for deposit accounts, such as money market accounts, that are subject to re-pricing based on current market conditions. Re-pricing margins are also determined for adjustable rate assets and incorporated in the model. Investment securities and borrowings with option provisions are examined on an individual basis in each rate environment to estimate the likelihood of exercise. Prepayment assumptions for mortgage loans are calibrated using specific Bank experience while mortgage-backed securities are developed from industry standard models of prepayment speeds, based upon similar coupon ranges and degree of seasoning. Cash flows and maturities are then determined, and for certain assets, prepayment assumptions are estimated under different interest rate scenarios. Interest income and interest expense are then simulated under several hypothetical interest rate conditions including:

​

• | A flat interest rate scenario in which current prevailing rates are locked in and the only balance sheet fluctuations that occur are due to cash flows, maturities, new volumes, and re-pricing volumes consistent with this flat rate assumption;

49

Table of Contents

​

• | A 200 basis point rise or decline in interest rates (or as appropriate given the absolute level of market rates) applied against a parallel shift in the yield curve over a twelve-month horizon together with a dynamic balance sheet anticipated to be consistent with such interest rate changes;

​

• | Various non-parallel shifts in the yield curve, including changes in either short-term or long-term rates over a twelve-month horizon, together with a dynamic balance sheet anticipated to be consistent with such interest rate changes; and

​

• | An extension of the foregoing simulations to each of two, three, four and five year horizons to determine the interest rate risk with the level of interest rates stabilizing in years two through five. Even though rates remain stable during this two to five year time period, re-pricing opportunities driven by maturities, cash flow, and adjustable rate products will continue to change the balance sheet profile for each of the interest rate conditions.

​

Changes in net interest income based upon the foregoing simulations are measured against the flat interest rate scenario and actions are taken to maintain the balance sheet interest rate risk within established policy guidelines.

​

In 2020, behavioral assumptions regarding both core deposits and residential loans were modified to incorporate the results of a third party model to better reflect the Bank’s unique position and geographic footprint. As of December 31, 2020, interest rate sensitivity modeling results indicate that the Bank’s balance sheet was asset sensitive over the one- and two-year horizons.

​

The following table presents the changes in sensitivities on net interest income for the years ended December 31, 2020 and 2019:

​

​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
Change in Interest Rates-Basis Points (Rate Ramp) | ​ | 1 - 12 Months | ​ | 13 - 24 Months |
(in thousands, except ratios) | ​ | $ Change | ​ | % Change | ​ | $ Change | ​ | % Change |
At December 31, 2020 |  | ​ |  |  |  |  | ​ |  |  |  | ​
-100 | ​ | $ | (2,368) |  | (2.6) | % | $ | (8,716) |  | (9.5) | %
+200 | ​ |  | 7,080 |  | 7.7 | ​ |  | 16,945 |  | 18.4 | ​
At December 31, 2019 | ​ |  |  |  |  | ​ |  | ​ |  |  | ​
-100 | ​ |  | (961) |  | (1.0) | ​ |  | (3,645) |  | (3.7) | ​
+200 | ​ |  | 651 |  | 0.7 | ​ |  | 3,246 |  | 3.3 | ​

​

Assuming short-term and long-term interest rates decline 100 basis points from current levels (i.e., a parallel yield curve shift) and the Bank’s balance sheet structure and size remain at current levels, management believes net interest income will deteriorate over the one year horizon while deteriorating further from that level over the two-year horizon.

​

Assuming the Bank’s balance sheet structure and size remain at current levels and the Federal Reserve increases short-term interest rates by 200 basis points with the balance of the yield curve shifting in parallel with these increases, management believes net interest income will improve over both the one and two-year horizons.

​

As compared to December 31, 2019, the year-one sensitivity in the down 100 basis points scenario is down with the year-two sensitivities in the down 100 basis points scenario lower as well. In the year-one and year-two up 200 basis points scenario, results are meaningfully improved on a year-over-year basis.

​

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

​

50

Table of Contents

As market conditions vary from those assumed in the sensitivity analysis, actual results may also differ due to: prepayment and refinancing levels deviating from those assumed; the impact of interest rate changes, caps or floors on adjustable rate assets; the potential effect of changing debt service levels on customers with adjustable rate loans; depositor early withdrawals and product preference changes; and other such variables. The sensitivity analysis also does not reflect additional actions that the Bank’s Senior Executive Team and Board of Directors might take in responding to or anticipating changes in interest rates, and the anticipated impact on the Bank’s net interest income.

ITEM 8. CONSOLIDATED FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Shareholders and the Board of Directors of Bar Harbor Bankshares and Subsidiaries

Opinion on the Internal Control Over Financial Reporting

We have audited the accompanying consolidated balance sheets of Bar Harbor Bankshares and Subsidiaries (the Company) as of December 31, 2020 and 2019, 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, 2020, 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, 2020 and 2019, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2020, 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, 2020, 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 10, 2021 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 audit 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.

Critical Audit Matters

The critical audit matters communicated below are matters arising from the current period audit of the financial statements that were communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.

Qualitative Reserve in the Allowance for Loan Losses

As described in Notes 1 and 4 of the consolidated financial statements, the Company’s allowance for loan losses totaled $19.1 million as of December 31, 2020. The allowance is comprised of four distinct reserve components: (1) specific reserves related to loans individually evaluated; (2) quantitative reserves related to loans collectively evaluated; (3) qualitative reserves related to loans collectively evaluated; and (4) an estimate is made for losses incurred during the loss emergence period for each loan category within the collectively evaluated pools. As of December 31, 2020, specific reserves related to loans individually evaluated totaled $730 thousand and the reserve associated with loans collectively evaluated, including the quantitative, qualitative and loss emergence period estimates, totaled, $18.4 million.

52

Table of Contents

For loans that are collectively evaluated, the Company segregates loans into two general loan pools: substandard and pass rated by loan type. The reserve for loans collectively evaluated is established through historical loss experience of the loan pools over their respective loss emergence periods which are then adjusted for potential risks factors that could result in actual losses deviating from prior loss experience. The Company has considered these qualitative risk factors to be: (1) lending policies and procedures, (2) business conditions, (3) volume and nature of the loan portfolio, (4) experience, ability and depth of lending management, (5) problem loan trends, (6) quality of the Company’s loan review system, (7) concentrations in the loan portfolio, (8) competition, legal, and regulatory environment, and (9) collateral coverage and loan to value. Arriving at an appropriate level of allowance for loan losses, specifically the qualitative reserve, involves a high degree of judgment by management and future adjustments may be necessary if there are significant changes in conditions.

We identified the qualitative reserve for loans collectively evaluated in the allowance for loan losses as a critical audit matter due to the high degree of auditor judgment required in order to evaluate the subjective assumptions made by management within the reserve. Our audit procedures related to management’s evaluation and establishment of the qualitative reserve for loans collectively evaluated in the allowance for loan losses include the following, among others:

| ● | We obtained an understanding of the relevant controls related to the qualitative factors applied to the qualitative reserve for loans collectively evaluated in the allowance for loan losses and tested such controls for design and operating effectiveness, including controls over management’s establishment, review and approval of the qualitative factors and the data used in determining the qualitative factors.

| ● | We tested management’s process and significant judgments in the evaluation and establishment of the qualitative reserve, which included:

| o | Evaluating the reasonableness of management’s judgments by validating the source of information used by management with the relevant internal or external information from which it was derived, as well as testing the completeness and accuracy of the source data used by management.

| o | Evaluating the reasonableness of management’s judgments related to the adjustments given to the qualitative factors by evaluating the adjustments for the proper magnitude and directional consistency based on the data utilized in the determination of the qualitative factors.

Goodwill Impairment Assessment

As described in Notes 1 and 6 of the consolidated financial statements, the Company’s goodwill balance was $119.5 million as of December 31, 2020. The Company performs a goodwill impairment test annually as of September 30, or whenever certain triggering events occur or there are circumstances that would more likely than not reduce the fair value of the reporting unit below its carrying amount are identified. Management estimates the fair value of the reporting unit by considering multiple valuation techniques, which include the income approach (discounted cash flow method) and the market approach (combination of comparable public companies and acquisition transactions). These valuation techniques consider various assumptions about projected financial results, business plans, discount rates, valuation multiples, and growth rates, among others.

We identified the impairment assessment of goodwill as a critical audit matter due to the high degree of auditor judgement, subjectivity, and effort in order to evaluate the fair value of the reporting unit due to the judgements made by management in the estimation of the Company’s future cash flows (including consideration of projected financial results and business plans), the components used in determining the discount and growth rates, the valuation multiples used, and the market data used. In addition, the audit effort involved the use of internal professionals with specialized skill and knowledge in the field of business valuation.

Our audit procedures related to the goodwill impairment assessments performed throughout the year included the following:

| ● | We obtained an understanding of the relevant controls and tested such controls for design and operating effectiveness related to management’s review of the fair value of the reporting unit calculation, including a review

53

Table of Contents

|  | of the accuracy and completeness of the inputs to the calculation as well as the review of the judgements made by management in the calculation.

| ● | We evaluated management’s process for developing the fair value estimates of the reporting unit including evaluating the appropriateness of the income and market approaches used.

| ● | We tested the completeness and accuracy of the underlying data used in the fair value estimates by agreeing Company financial data to internal records and independently obtaining market data for a population of comparable companies.

| ● | We evaluated management’s cash flow projections and significant assumptions considered within the business plan by considering the current and past performance by the Company, consideration of the Company’s ability to meet financial projections, and the consistency of these assumptions with evidence obtained in other areas of the audit.

| ● | We used the assistance of internal specialists to assist in the evaluation of significant assumptions in the valuation methodology. This included:

| o | Evaluating the discount rate by comparing to publicly available market data and, as necessary, establishing an independent expectation of a market discount rate.

| o | Evaluating the long term growth rate by comparing to industry standard metrics and, as necessary, establishing an independent expectation of a long term growth rate.

| o | Evaluating the price multiples of comparable public companies by comparing management’s assumptions to market information publicly available for comparable companies.

| o | Evaluating the reasonableness and application of the methodologies used by management including the income approach and the market approach.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of presentation: The consolidated financial statements (the “financial statements”) of Bar Harbor Bankshares and its subsidiaries (the “Company” or “Bar Harbor”) have been prepared in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”). Bar Harbor Bankshares is a Maine Financial Institution Holding Company for the purposes of the laws of the state of Maine, and as such, is subject to the jurisdiction of the Superintendent of the Maine Bureau of Financial Institutions. These financial statements include the accounts of the Company, its wholly-owned subsidiary Bar Harbor Bank & Trust (the "Bank") and the Bank’s consolidated subsidiaries. The results of operations of companies or assets acquired are included only from the dates of acquisition. All material wholly-owned and majority-owned subsidiaries are consolidated unless U.S. GAAP requires otherwise.

Consolidation: The accompanying consolidated financial statements have been prepared in accordance with U.S. GAAP. The consolidated financial statements include the accounts of Bar Harbor Bankshares and its wholly-owned subsidiaries, Bar Harbor Bank & Trust, Bar Harbor Trust Services, Charter Trust Company and Cottage Street Corporation. All significant inter-company balances and transactions have been eliminated in consolidation. Assets held in a fiduciary capacity are not assets of the Company, but assets of customers, and therefore, are not included in the consolidated balance sheets.

Reclassifications: Whenever necessary, amounts in the prior years’ financial statements are reclassified to conform to current presentation. The reclassifications had no impact on net income in the Company’s consolidated income statement.

Use of estimates: In preparing financial statements in conformity with U.S. GAAP, management is required to make estimates and assumptions that affect the reported amount of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and revenues and expenses during the reporting period. Actual results could differ from those estimates. Material estimates that are particularly susceptible to change in the near term relate to the determination of the allowance for loan losses, other-than-temporary impairment on securities, income tax estimates, reviews of goodwill for impairment, and accounting for post-retirement plans.

Cash and Cash Equivalents: For purposes of reporting cash flows, cash and cash equivalents include cash on hand and amounts due from banks, interest-bearing deposits with other banks, federal funds sold, and other short-term investments with maturities less than 90 days. The Federal Reserve Bank requires the Bank to maintain certain reserve requirements of vault cash and/or deposits. On March 15, 2020, the Federal Reserve Board reduced reserve requirement ratios to zero percent effective March 26, 2020. This action eliminated reserve requirement for all depository institutions. The reserve requirement at December 31, 2019 was $23.1 million.

Securities: All securities held at December 31, 2020 and 2019 were classified as available-for-sale (“AFS”). Available for sale securities primarily consist of mortgage-backed securities, obligations of state and political subdivisions thereof, and corporate bonds and are carried at estimated fair value. Changes in estimated fair value of AFS securities, net of applicable income taxes, are reported in accumulated other comprehensive income (loss) as a separate component of shareholders’ equity unless deemed to be other-than-temporarily impaired (“OTTI”) as discussed below. The Company does not have any securities classified as trading or held-to-maturity.

Premiums and discounts on securities are amortized and accreted over the term of the securities using the interest method. Gains and losses on the sale of securities are recognized at the trade date using the specific-identification method and are shown separately in the Consolidated Statements of Income.

Other-Than-Temporary Impairments on Securities: The Company conducts an OTTI analysis of investment securities on a quarterly basis or more often if a potential loss-triggering event occurs. A write-down of a debt security is recorded when fair value is below amortized cost in circumstances where: (1) the Company has the intent to sell a security; (2) it is more likely than not that the Company will be required to sell the security before recovery of its amortized cost basis; or (3) the Company does not expect to recover the entire amortized cost basis of the security. If the Company intends to sell

a security or if it is more likely than not that the Company will be required to sell the security before recovery, an OTTI write-down is recognized in earnings equal to the entire difference between the security’s amortized cost basis and its fair value. If the Company does not intend to sell the security or it is not more likely than not that it will be required to sell the security before recovery, the OTTI write-down is separated into an amount representing credit loss, which is recognized in earnings, and an amount related to all other factors, which is recognized in other comprehensive income. To determine the amount related to credit loss on a debt security, the Company applies a methodology similar to that used for evaluating the impairment of loans.

Federal Home Loan Bank Stock: The Bank is a member of the Federal Home Loan Bank of Boston (“FHLB”). The Bank uses the FHLB for most of its wholesale funding needs. As a requirement of membership in the FHLB, the Bank must own a minimum required amount of FHLB stock, based primarily on its level of obligations with the FHLB. FHLB stock is a non-marketable equity security and therefore is reported at cost, which generally equals par value. Shares held in excess of the minimum required amount are generally redeemable at par value. Dividends from FHLB stock are reported in interest and dividend income.

The Company periodically evaluates FHLB stock for impairment based on the capital adequacy of the FHLB and its overall financial condition. Based on the capital adequacy, liquidity position and sustained profitability of the FHLB, management believes there is no impairment related to the carrying amount of the Bank’s FHLB stock as of December 31, 2020.

Loans Held for Sale: Residential loans originated with the intent to be sold in the secondary market are accounted for at the lower of cost or market (fair value). Fair value is primarily determined based on quoted prices for similar loans in active markets. Residential loans held for sale are generally sold with servicing rights retained. The carrying value of loans sold is reduced by the amount allocated to the servicing right. Gains and losses on sales of residential loans (sales proceeds minus carrying value) are recorded in non-interest income.

Loans: Loans are reported at their outstanding unpaid principal balances adjusted for charge-offs, the allowance for loan losses, the unamortized balance of any deferred fees or costs on originated loans and the unamortized balance of any premiums or discounts on loans purchased or acquired through mergers.

Interest on loans is accrued and credited to income based on the principal amount of loans outstanding.

Loan origination and commitment fees and direct loan origination costs are deferred, and the net amount is amortized as an adjustment of the related loans’ yield, using the level-yield method over the estimated lives of the related loans.

Acquired Loans: Loans acquired in acquisitions are initially recorded at fair value with no carryover of the related allowance for credit losses. Determining the fair value of the loans involves estimating the amount and timing of principal and interest cash flows initially expected to be collected on the loans and discounting those cash flows at an appropriate market rate of interest.

For loans that meet the criteria stipulated in ASC 310-30, “Loans and Debt Securities Acquired with Deteriorated Credit Quality,” the Company recognizes the accretable yield, which is defined as the excess of all cash flows expected at acquisition over the initial fair value of the loan, as interest income on a level-yield basis over the expected remaining life of the loan. The excess of the loan’s contractually required payments over the cash flows expected to be collected is the non-accretable difference. The non-accretable difference is not recognized as an adjustment of yield, a loss accrual, or a valuation allowance. The Company evaluates quarterly whether the timing and cash to be collected are reasonably expected. Subsequent significant increases in cash flows the Company expects to collect will first reduce any previously recognized valuation allowance and then be reflected prospectively as an increase to the level yield. Subsequent decreases in expected cash flows may result in the loan being considered impaired. Interest income is not recognized to the extent that the net investment in the loan would increase to an amount greater than the estimated payoff amount.

For loans that do not meet the ASC 310-30 criteria, the Company accretes interest income based on the contractually required cash flows. The Company subjects loans that do not meet the ASC 310-30 criteria to ASC 450, “Contingencies” by collectively evaluating these loans for an allowance for loan loss.

Table of Contents

Acquired loans that met the criteria for non-accrual of interest prior to the acquisition are considered performing upon acquisition, regardless of whether the customer is contractually delinquent, if the Company can reasonably estimate the timing and amount of the expected cash flows on such loans and if the Company expects to fully collect the new carrying value of the loans. As such, the Company may no longer consider the loan to be non-accrual or nonperforming and may accrue interest on these loans, including the impact of any accretable yield.

Non-performing loans: Residential real estate and home equity loans are generally placed on non-accrual status when reaching 90 days past due, or in process of foreclosure, or sooner if considered appropriate by management. Consumer loans are generally placed on non-accrual when reaching 90 days or more past due, or sooner if considered appropriate by management. Secured consumer loans are written down to net realizable value and unsecured consumer loans are charged-off upon reaching 120 days past due. Commercial real estate loans and commercial business loans that are 90 days or more past due are generally placed on non-accrual status, unless secured by sufficient cash or other assets immediately convertible to cash, and the loan is in the process of collection. Commercial real estate and commercial business loans may be placed on non-accrual status prior to the 90 days delinquency date if considered appropriate by management.

When a loan has been placed on non-accrual status, previously accrued and uncollected interest is reversed against interest on the loan. The interest on non-accrual loans is accounted for using the cash-basis or cost-recovery method depending on corresponding credit risk, until qualifying for return to accrual status. A loan can be returned to accrual status when collectability of principal is reasonably assured and the loan has performed for a period of time, generally six months.

Impaired loans: A loan is considered impaired when, based on current information and events, it is probable that the Company will not be able to collect all amounts due from the borrower in accordance with the contractual terms of the loan, including scheduled interest payments.

Factors considered by management in determining impairment include payment status and collateral value. In considering loans for evaluation of impairment, management generally excludes smaller balance, homogeneous loans; residential mortgage loans, home equity loans, and all consumer loans, unless such loans were restructured in a troubled debt restructuring. These loans are collectively evaluated for risk of loss.

When a loan has been identified as being impaired, the amount of impairment is measured based on the present value of expected future cash flows discounted at the loan’s effective interest rate, the loan’s observable market price, or the estimated fair value of the collateral, less any selling costs, if the loan is collateral-dependent. If the measurement of the impaired loan is less than the recorded investment in the loan (including accrued interest, net of deferred loan fees or costs, and unamortized premiums or discounts), impairment is recognized by establishing or adjusting an existing allocation of the allowance for loan losses, or by recording a partial charge-off of the loan to its fair value. Interest payments made on impaired loans are typically applied to principal unless collectability of the principal amount is reasonably assured, in which case, interest income may be accrued or recognized on a cash basis.

Loans Modified in a Troubled Debt Restructuring: Loans are considered to have been modified in a troubled debt restructuring when, due to a borrower’s financial difficulties, the Company makes certain concessions to the borrower that it would not otherwise consider. Modifications may include interest rate reductions, principal or interest forgiveness, forbearance, and other actions intended to minimize economic loss and to avoid foreclosure or repossession of collateral. Generally, a non-accrual loan that has been modified in a troubled debt restructuring remains on non-accrual status for a period of at least 6 months to demonstrate that the borrower is able to meet the terms of the modified loan.

However, performance prior to the modification, or significant events that coincide with the modification, are included in assessing whether the borrower can meet the new terms and may result in the loan being returned to accrual status at the time of loan modification or after a shorter performance period. If the borrower’s ability to meet the revised payment schedule is uncertain, the loan remains on non-accrual status.

Loan Modifications under the CARES Act: The CARES Act provides that a financial institution may elect to suspend (1) the requirements under GAAP for certain loan modifications that may otherwise be categorized as a troubled debt restructuring (“TDR”) and (2) any determination that such loan modifications would be considered a TDR, including the related impairment for accounting purposes.

Allowance for Loan Losses: The allowance for loan losses (the “allowance”) is a significant accounting estimate used in the preparation of the Company’s consolidated financial statements. The allowance is available to absorb losses inherent in the current loan portfolio and is maintained at a level that, in management’s judgment, is appropriate for the amount of risk inherent in the loan portfolio, given past and present conditions. The allowance is increased by provisions charged to operating expense and by recoveries on loans previously charged off, and is decreased by loans charged off as uncollectible.

The allowance is calculated in accordance with ASC 310 - Receivables and ASC 450 - Contingencies. Under the guidance of ASC 310, specific allowances are established in cases where management has identified significant conditions or circumstances related to individual loans where the probability of a loss may be incurred. Credit loss estimates for loans without specific allowances are determined under the guidance of ASC 450, which includes portfolio segmentation based on similar risk characteristics, determination of estimated historical loss rates, calculation of a time-based loss emergence and confirmation periods, and adjustments for certain qualitative risk factors.

Arriving at an appropriate level of allowance for loan losses involves a high degree of judgment. The determination of the adequacy of the allowance and provisioning for estimated losses is evaluated regularly based on review of loans, with particular emphasis on non-performing and other loans that management believes warrant special consideration.

While management uses available information to recognize losses on loans, changing economic conditions and the economic prospects of the borrowers may necessitate future additions or reductions to the allowance. In addition, various regulatory agencies, as an integral part of their examination process, periodically review the Bank’s allowance, which also may necessitate future additions or reductions to the allowance, based on information available to them at the time of their examination.

Refer to Note 4 - Allowance for Loan Losses, for further information, including the Company’s loan loss estimation methodology.

Reserve for Unfunded Commitments: The unfunded reserve is a component of other liabilities and represents the estimate for probable credit losses inherent in unfunded commitments to extend credit. Unfunded commitments to extend credit include banker’s acceptances, and standby and commercial letters of credit. The process used to determine the unfunded reserve is consistent with the process for determining the allowance, as adjusted for estimated funding probabilities or loan and lease equivalency factors. The level of the unfunded reserve is adjusted by recording on an expense or recovery in other noninterest expense. Reserve for unfunded commitments are classified in other liabilities on the Company’s Consolidated Balance Sheet.

Premises and Equipment: Land is carried at cost. Premises and equipment and related improvements are stated at cost less accumulated depreciation. Depreciation is computed on the straight-line method over the lesser of the lease term or estimated useful lives of related assets; generally 5 to 39 years for premises and three to seven years for furniture and equipment. Software costs are stated at cost less accumulated depreciation within other assets on the Consolidated Statements of Condition. Amortization expense on software is calculated using the straight-line method over the estimated useful lives of the related assets.

Transfers of Financial Assets: Transfers of an entire financial asset, group of entire financial assets, or a participating interest in an entire financial asset are accounted for as sales when control over the assets has been surrendered. Control over transferred assets is deemed to be surrendered when (1) the assets have been isolated from the Company, (2) the transferee obtains the right to pledge or exchange the transferred assets, and (3) the Company does not maintain effective control over the transferred assets.

Other Real Estate Owned: Other real estate owned consists of properties acquired through foreclosure proceedings or acceptance of a deed-in-lieu of foreclosure. These properties are recorded at fair value less estimated costs to sell the property. Initially at transfer if the recorded investment in the loan exceeds the property’s fair value at the time of acquisition, a charge-off is recorded against the allowance. If the fair value of the property initially at transfer exceeds the carrying amount of the loan, the excess is recorded either as a recovery to the allowance if a charge-off had previously been recorded, or as a gain on initial transfer in other non-interest income. Subsequent decreases in the property’s fair

65

Table of Contents

value and operating expenses of the property are recognized through charges to other non-interest expense. The fair value of the property acquired and ongoing valuation is based on third-party appraisals, broker price opinions, recent sales activity, or a combination thereof, subject to management judgment. Due to changing market conditions the amount ultimately realized on the other real estate owned may differ from the amounts reflected in the financial statements.

Goodwill: In connection with acquisitions, the Company generally records as assets on its consolidated financial statements both goodwill and other intangible assets, such as core deposit and acquired customer relationship intangibles.

Goodwill represents the excess of the purchase price over the fair value of net assets acquired in accordance with the purchase method of accounting for business combinations. Goodwill is not amortized but, instead, is subject to impairment tests on at least an annual basis, or more frequently, if an event occurs or circumstances change that reduce the fair value of a reporting unit below its carrying amount. The impairment testing process is conducted by assigning assets and goodwill to each reporting unit. Currently, the Company’s goodwill is evaluated at the entity level as there is only one reporting unit. The Company, at our discretion, assesses certain qualitative factors to determine if it is more likely than not that the fair value of the reporting unit is less than its carrying value. An impairment charge is recognized if the carrying fair value of goodwill exceeds the implied fair value of goodwill.

Refer to Note 6 – Goodwill and Other Intangibles, for further information, including the Company’s loan loss estimation methodology

Other Intangible Assets: Intangible assets are acquired assets that lack physical substance but can be distinguished from goodwill because of contractual or other legal rights or the asset is capable of being sold or exchanged either on its own or in combination with a related contract, asset or liability. The fair value of these assets are generally determined based on appraisals and management assesses the recoverability of these intangible assets whenever events or changes in circumstances indicate that their carrying value may not be recoverable. These other intangible assets primarily consist of core deposit and acquired customer relationship intangible assets arising from the whole bank and branch acquisitions are amortized on an accelerated method over their estimated useful lives.

Bank-Owned Life Insurance: Bank-owned life insurance (“BOLI”) represents life insurance on the lives of certain current and retired employees who had provided positive consent allowing the Bank to be the beneficiary of such policies. Increases in the cash value of the policies, as well as insurance proceeds received in excess of the cash value, are recorded in other non-interest income, and are not subject to income taxes.

Capitalized Servicing Rights: Capitalized servicing rights are recognized as assets when residential loans are sold and the rights to service those loans are retained.

The Company’s capitalized servicing rights are initially recorded at fair value. Fair values are established by using a discounted cash flow model to calculate the present value of estimated future net servicing income. Changes in the fair value of capitalized servicing rights are primarily due to changes in valuation inputs, assumptions, and the collection and realization of expected cash flows. However, these capitalized servicing rights are amortized in proportion to and over the period of estimated net servicing income, which includes prepayment assumptions. An impairment analysis is prepared on a quarterly basis by estimating the fair value of the capitalized servicing rights and comparing that value to the carrying amount. A valuation allowance is established when the carrying amount of these capitalized servicing rights exceeds fair value. The capitalized servicing rights are included in other assets on the Company’s consolidated balance sheet.

Derivative Financial Instruments: The Company recognizes all derivative instruments on the consolidated balance sheet at fair value. On the date the derivative instrument is entered into, the Company designates whether the derivative is part of a hedging relationship (i.e., cash flow or fair value hedge). The Company formally documents relationships between hedging instruments and hedged items, as well as its risk management objective and strategy for undertaking hedge transactions. The Company also assesses, both at the hedge’s inception and on an ongoing basis, whether the derivatives used in hedging transactions are highly effective in offsetting the changes in cash flows or fair values of hedged items. The fair value of the derivative is reflected on the Consolidated Balance Sheet in either other assets or liabilities.

66

Table of Contents

Changes in the fair value of derivative instruments that are highly effective and qualify as cash flow hedge are recorded in other comprehensive income (loss). Any ineffective portion is recorded in earnings. For fair value hedges that are highly effective, the gain or loss on the derivative and the loss or gain on the hedged item attributable to the hedged risk are both recognized in earnings, with the differences (if any) representing hedge ineffectiveness. The Company discontinues hedge accounting when it is determined that the derivative is no longer highly effective in offsetting changes of the hedged risk on the hedged item, or management determines that the designation of the derivative as a hedging instrument is no longer appropriate.

Net cash settlements on derivatives that qualify for hedge accounting are recorded in interest income or interest expense based on the item being hedged. Net cash settlements on derivatives that do not quality for hedge accounting are reporting in non-interest income. Cash flows on hedges are classified in the cash flow statement the same as cash flows of the items being hedged.

The Company enters into commitments to fund mortgage loans with borrowers (interest rate locks) and forward commitments for the future delivery of these mortgage loans for sale on the secondary market. These mortgage banking derivatives are classified as free standing derivatives to hedge against inherent interest rate and pricing risk associated with selling loans. The commitments to lend generally terminate once the loan is funded, the lock period expires or the borrower decides not to contract for the loan. The forward commitments generally terminate once the loan is sold or the commitment period expires. These commitments are considered derivatives which are accounted for by recognizing their estimated fair value on the Consolidated Balance Sheets in either other assets or other liabilities.

Senior and Subordinated Borrowings: The Company’s senior borrowings include retail and wholesale repurchase agreements, FHLB overnight, FHLB short-term and long-term advances, federal funds purchased, credit facilities, and line of credit advances. Subordinated borrowings consist of subordinated notes issued to investors. The Company is required to post collateral for certain borrowings, for which it, generally, posts loans and/or investment securities as collateral.

Off-Balance Sheet Financial Instruments: In the ordinary course of business, the Company has entered into off- balance sheet financial instruments consisting of commitments to extend credit, unused or unadvanced loan funds and letters of credit. Such financial instruments are recorded in the consolidated financial statements when they are funded or related fees are incurred or received.

Stock Based Compensation: The Company has equity award plans that include stock options, restricted stock awards restricted stock units and performance stock units, which are described more fully in Note 14 - Stock Based Compensation Plans of the Consolidated Financial Statements. The Company recognizes expenses for stock options and restricted awards based on the fair value of these awards as of the grant date. For restricted stock units and performance stock units the expense is recognized over the vesting periods of the grants. The Company uses its treasury shares for issuing shares upon option exercises, restricted stock awards, restricted stock unit vesting and performance stock unit vesting.

Employee Stock Purchase Plan: The Company recognizes expense based difference between the market price of shares and the discounted price of the plan from participant enrollment over each six month enrollment period.

Employee Benefit Plans: The Company has non-qualified supplemental executive retirement agreements with certain retired officers. The agreements provide supplemental retirement benefits payable in installments over a period of years upon retirement or death. The Company recognized the net present value of payments associated with the agreements over the service periods of the participating officers. Interest costs continue to be recognized on the benefit obligations. The Company also has a supplemental executive retirement agreement with a certain current executive officer. This agreement provides a stream of future payments in accordance with individually defined vesting schedules upon retirement, termination, or in the event that the participating executive leaves the Company following a change of control event. The Company recognizes the net present value of payments associated with these agreements over the service periods of the participating executive officers. Upon retirement, interest costs will continue to be recognized on the benefit obligation.

The Company recognizes the over-funded or under-funded status of post-retirement benefit plans as a liability or asset on the balance sheet in other liabilities or other assets and recognizes changes in that funded status through other

comprehensive income (loss). Gains and losses, prior service costs and credits, and any remaining transition amounts that have not yet been recognized through net periodic benefit costs are recognized in accumulated other comprehensive income/(loss), net of tax effects, until they are amortized as a component of net periodic cost. The measurement date, which is the date at which the benefit obligation and plan assets are measured, is the Company’s fiscal year end.

Employee 401(k) expenses are recognized for the amount of the Company’s matching contributions.

Income Taxes: The Company uses the asset and liability method of accounting for income taxes. Under this method, deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. If current available information indicates that it is more likely than not that deferred tax assets will not be realized, 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.

Treasury Stock: Shares of the Company’s common stock that are repurchased are recorded in treasury stock at cost. On the date of subsequent re-issuance, the treasury stock account is reduced by the cost of such stock on an average cost basis.

Earnings Per Share: Basic earnings per share excludes dilution and is computed by dividing income available to common shareholders by the weighted average number of common shares outstanding for the period. Diluted earnings per share reflect the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock or resulted in the issuance of common stock that then shared in the earnings of the Company, such as the Company’s dilutive stock options.

Revenue Recognition: The Company recognizes revenue in accordance with ASC 606, "Revenue from Contracts with Customers." ASC 606 requires the Company to follow a five step process: (1) identify the contract(s) with a customer, (2) identify the performance obligations in the contract, (3) determine the transaction price, (4) allocate the transaction price to the performance obligations in the contract, and (5) recognize revenue when (or as) the Company satisfies a performance obligation. Revenue recognition under ASC 606 depicts the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for the goods or service. See Note 16 - Revenue from Contracts with Customers of the Company’s Consolidated Financial Statements for additional information on revenue recognition.

Wealth Management: Wealth management assets held in a fiduciary or agent capacity are not included in the accompanying Consolidated Balance Sheets because they are not assets of the Company. Trust and investment management fees is primarily comprised of fees earned from consultative investment management, trust administration, tax return preparation, and financial planning. The Company’s performance obligation is generally satisfied over time and the resulting fees are recognized monthly, based on the daily accrual of the market value of the investment accounts and the applicable fee rate.

​

Marketing Costs: Marketing costs are expensed as incurred.

Segment Reporting: An operating segment is defined as a component of a business for which separate financial information is available that is evaluated regularly by the chief operating decision-maker in deciding how to allocate resources and evaluate performance. The Company has determined that its operations are solely in the community banking industry and include traditional community banking services, including lending activities, acceptance of demand, savings and time deposits, business services, investment management, trust and third-party brokerage services. These products and services have similar distribution methods, types of customers and regulatory responsibilities. Accordingly, segment information is not presented in the Consolidated Financial Statements.

ASU 2016-13, Measurement of Credit Losses on Financial Instruments ASU 2018‑19, Codification Improvements to ASU 2016-13 | ​ | ​ | This ASU amends Topic 326, Financial Instruments- Credit Losses to replace the current incurred loss accounting model with a current expected credit loss approach ("CECL") for financial instruments measured at amortized cost and other commitments to extend credit, such as of balance sheet credit exposures (loan commitments, unused line of credit and stand-by letters of credit). The amendments require entities to consider all available relevant information when estimating current expected credit losses, including details about past events, current conditions, and reasonable and supportable forecasts. The resulting allowance for credit losses is to reflect the portion of the amortized cost basis that the entity does not expect to collect. The amendments also eliminate the current accounting model for purchased credit impaired loans and certain off-balance sheet exposures. Additional quantitative and qualitative disclosures are required upon adoption. While the CECL model does not apply to available for sale debt securities, the ASU does require entities to record an allowance when recognizing credit losses for available for sale securities with unrealized losses, rather than reduce the amortized cost of the securities by direct write-offs. The guidance will require companies to recognize improvements to estimated credit losses immediately in earnings rather than interest income over time. The ASU should be adopted on a modified retrospective basis. Entities that have loans accounted for under ASC 310-30 at the time of adoption should prospectively apply the guidance in this amendment for purchase credit deteriorated assets. | ​ | ​ | January 1, 2020 ​ | ​ | ​ | Adoption of this ASU is expected to primarily change how the Company estimates credit losses with the application of the expected credit loss model. The Company will apply the standard's provisions as a cumulative effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective (i.e., modified retrospective approach). The Company's CECL implementation efforts in the fourth quarter focused on the finalization and board approval of the final CECL model, completed modelling of off-balance sheet credit risks, completed formal governance and control documentation, and developed and presented revised disclosures for board approval. The ASU was originally effective for the Company beginning in the first quarter of 2020; however, after the CARES Act was enacted on March 27, 2020, the Securities and Exchange Commission (SEC) staff clarified that once the deferral was elected by a registrant, Dec. 31, 2020, adoption of CECL was required, retrospective to Jan. 1, 2020 (ignoring an early termination of the national emergency). Under the amendments, a registrant electing the delay under the CARES Act is further delayed until Jan. 1, 2022, effective as of Jan. 1, 2022 (absent an early termination of the national emergency). With regard to the amendments to Section 4014, the SEC staff indicated it would not object to a registrant early adopting on Dec. 31, 2020, retrospective to Jan. 1, 2020, or Jan. 1, 2021, effective as of Jan. 1, 2021. The Company elected to delay the adoption to Jan. 1, 2021 to allow for a more comparable quarterly presentation as we report in 2021. Had we adopted CECL at year end 2020, the loan loss reserve as a percentage of total loans would have been 95 basis points compared to 74 basis points reported under the incurred loss model. The 95 basis points may change in the first quarter of 2021 based primarily on any changes in economic forecasts.
ASU 2018-14 Compensation- Disclosure Requirements for Defined Pension Plans Topic 715-20 | ​ | ​ | This ASU makes minor changes to the disclosure requirements for employers that sponsor defined benefit pension and/or other post-retirement benefit plans. | ​ | ​ | January 1, 2021 Early adoption is permitted. | ​ | ​ | Adoption of this ASU is not expected to have a material impact on the Company's consolidated financial statements.

ASU 2020-01, Investments—Equity Securities, Investments Equity Method and Joint Ventures, and Derivatives and Hedging | ​ | ​ | In January 2016, the FASB issued Accounting Standards Update No. 2016-01, Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities, which added Topic 321, Investments – Equity Securities, and made targeted improvements to address certain aspects of accounting for financial instruments. The amendments in this Update affect all entities that apply the guidance in Topics 321, 323, and 815 and (1) elect to apply the measurement alternative or (2) enter into a forward contract or purchase an option to purchase securities that, upon settlement of the forward contract or exercise of the purchased option, would be accounted for under the equity method of accounting. The amendments in this Update clarify certain interactions between the guidance to account for certain equity securities under Topic 321, the guidance to account for investments under the equity method of accounting in Topic 323, and the guidance in Topic 815, which could change how an entity accounts for an equity security under the measurement alternative or a forward contract or purchased option to purchase securities that, upon settlement of the forward contract or exercise of the purchased option, would be accounted for under the equity method of accounting or the fair value option in accordance with Topic 825, Financial Instruments. The amendments in this Update should be applied prospectively. | ​ | ​ | December 15, 2020 | ​ | ​ | The Company has been evaluating our equity method investments which primarily consist of community limited partnership investments to ensure compliance with the new guidance prospectively in 2021. Adoption of this ASU is not expected to have a material impact on the Company's consolidated financial statements.
ASU 2020-04 Facilitation of the Effects of Reference Rate Reform, Topic 848, as amended in ASU 2021-01 | ​ | ​ | This ASU provides temporary optional expedients and exceptions to GAAP guidance on contract modifications and hedge accounting to ease the financial reporting burdens of the expected market transition from the London Interbank Offered Rate ("LIBOR") and other interbank offered rates to alternative reference rates, such as the Secured Overnight Financing Rate ("SOFR"). For instance, companies can (1) elect not to apply certain modification accounting requirements to contracts affected by reference rate reform, if certain criteria are met. A company that makes this election would not have to re-measure the contracts at the modification date or reassess a previous accounting determination. Companies can also (2) elect various optional expedients that would allow them to continue applying hedge accounting for hedging relationships affected by reference rate reform, if certain criteria are met. Finally, companies can (3) make a one-time election to sell and/or reclassify held-to-maturity debt securities that reference an interest rate affected by reference rate reform. | ​ | ​ | May be elected through December 31, 2022. | ​ | ​ | The Company is currently evaluating all of its contracts, hedging relationships and other transactions that will be effected by reference rates that are being discontinued and determining which elections need to be made.

Securities Impairment

As a part of the Company’s ongoing security monitoring process, the Company identifies securities in an unrealized loss position that could potentially be other-than-temporarily impaired. For the twelve months ended December 31, 2020, 2019 and 2018 the Company did not record any other-than-temporary impairment (“OTTI”) losses.

​

The Company expects to recover its amortized cost basis on all debt securities in its AFS portfolio, as unrealized losses are the result of changes in the interest rate environment and other market factors. Furthermore, the Company does not intend to sell nor does it anticipate that it will be required to sell any of its securities in an unrealized loss position as of December 31, 2020, prior to this recovery. The Company’s ability and intent to hold these securities until recovery is supported by the Company’s strong capital and liquidity positions as well as its historically low portfolio turnover.

The following summarizes, by investment security type, the basis for the conclusion that the debt securities in an unrealized loss position within the Company’s AFS were not other-than-temporarily impaired at December 31, 2020:

US Government-sponsored enterprises

35 out of the total 571 securities in the Company’s portfolios of AFS US Government-sponsored enterprises were in unrealized loss positions. Aggregate unrealized losses represented 1.04% of the amortized cost of securities in unrealized loss positions. The FNMA and FHLMC guarantee the contractual cash flows of all of the Company’s US Government- sponsored enterprises. The securities are investment grade rated and there were no material underlying credit downgrades during the year. All securities are performing.

US Government agencies

10 out of the total 159 securities in the Company’s portfolios of AFS US Government agency securities were in unrealized loss positions. Aggregate unrealized losses represented 1.14% of the amortized cost of securities in unrealized loss positions. The Government National Mortgage Association (“GNMA”) guarantees the contractual cash flows of all of the Company’s US government agency securities. The securities are rated investment grade and there were no material underlying credit downgrades during the year. All securities are performing.

Private-label

9 of the total 16 securities in the Company’s portfolio of AFS private-label mortgage-backed securities were in unrealized loss positions. Aggregate unrealized losses represented 0.72% of the amortized cost of securities in unrealized loss positions. Based upon the foregoing considerations, and the expectation that the Company will receive all of the future contractual cash flows related to the amortized cost on these securities, the Company does not consider there to be any additional other-than-temporary impairment with respect to these securities.

Obligations of states and political subdivisions thereof

2 of the total 142 securities in the Company’s portfolio of AFS municipal bonds and obligations were in unrealized loss positions. Aggregate unrealized losses represented 0.12% of the amortized cost of securities in unrealized loss positions. The Company continually monitors the municipal bond sector of the market carefully and periodically evaluates the appropriate level of exposure to the market. At this time, the Company believes the bonds in this portfolio carry minimal risk of default and the Company is appropriately compensated for that risk. There were no material underlying credit downgrades during the year. All securities are performing.

Corporate bonds

11 of the total 33 securities in the Company’s portfolio of AFS corporate bonds were in an unrealized loss position. The aggregate unrealized loss represents 2.45% of the amortized cost of securities in unrealized loss positions. The Company reviews the financial strength of all of these bonds and has concluded that the amortized cost remains supported by the expected future cash flows of these securities.

The carrying amount of the acquired loans at December 31, 2020 totaled $598.1 million. A subset of these loans was determined to have evidence of credit deterioration at the acquisition date, which is accounted for in accordance with ASC 310-30. These purchased credit-impaired loans presently maintain a carrying value of $12.7 million (and a note balance of $16.3 million). These loans are evaluated for impairment through the periodic reforecasting of expected cash flows. Loans considered not impaired at acquisition date had a carrying amount of $585.4 million.

Troubled Debt Restructuring Loans

The Company’s loan portfolio also includes certain loans that have been modified in a Troubled Debt Restructuring ("TDR"), where economic concessions have been granted to borrowers who have experienced or are expected to experience financial difficulties. These concessions typically result from the Company’s loss mitigation activities and could include reductions in the interest rate, payment extensions, forgiveness of principal, forbearance, or other actions. Certain TDRs are classified as non-performing at the time of restructure and may only be returned to performing status after considering the borrower’s sustained repayment performance for a reasonable period, generally six months. TDRs are evaluated individually for impairment and may result in a specific allowance amount allocated to an individual loan.

The following tables include the recorded investment and number of modifications identified during the twelve months ended December 31, 2020, 2019 and 2018, respectively. The table includes the recorded investment in the loans prior to a modification and also the recorded investment in the loans after the loans were restructured. Modifications may include adjustments to interest rates, payment amounts, extensions of maturity, court ordered concessions or other actions intended to minimize economic loss and avoid foreclosure or repossession of collateral.

​

For the twelve months ended December 31, 2020, 2019 and 2018, there were no loans that were restructured that had subsequently defaulted during the period. The evaluation of certain loans individually for specific impairment includes loans that were previously classified as TDRs or continue to be classified as TDRs.

Foreclosure

As of December 31, 2020, the Company had no bank-owned residential real estate property. As of December 31, 2019, the Company maintained bank-owned residential real estate property with a fair value of $2.2 million. Additionally, residential mortgage loans collateralized by real estate property that are in the process of foreclosure as of December 31, 2020 and December 31, 2019 totaled $633 thousand and $810 thousand, respectively.

Loan Concentrations

Loan concentrations in specific industries may occasionally emerge as a result of economic conditions, changes in local demands, natural loan growth and runoff. At December 31, 2020 the largest industry concentration outside of commercial real estate was the hospitality industry which represents 11% or $276.4 million of the Company’s total loan portfolio, compared with 8.6% or $227.0 million at December 31, 2019.

Loans to Related Parties

In the ordinary course of business, the Bank has made loans at prevailing rates and terms to directors, officers and other related parties. In management’s opinion, such loans do not present more than the normal risk of collectability or incorporate other unfavorable features, and were made under terms that are consistent with the Bank’s lending policies.

Mortgage Banking

The Bank sells loans in the secondary market and retains the ability to service many of these loans. The Bank earns fees for the servicing provided. At year end 2020 and 2019, the Company was servicing loans for participants totaling $596.3 million and $497.2 million, respectively. Loans serviced for others are not included in the accompanying consolidated balance sheets. The risks inherent in servicing assets relate primarily to changes in prepayments that result from shifts in interest rates. Contractually-specified servicing fees were $1.3 million for the years ended 2020, 2019, and 2018, and is included as a component of other income within non- interest income.

Servicing rights activity during 2020 and 2019, included in other assets, was as follows:

NOTE 4. ALLOWANCE FOR LOAN LOSSES

The allowance for loan losses is maintained at a level considered adequate to provide for an estimate of probable credit losses inherent in the loan portfolio. The allowance is increased by the provision charged to operating expense and reduced by net charge-offs. Loans are charged against the allowance for loan losses when the Company believes collectability has declined to a point where there is a distinct possibility of some loss of principal and interest. While the Company uses the best information available to make the evaluation, future adjustments may be necessary if there are significant changes in conditions.

The allowance is comprised of four distinct reserve components: (1) specific reserves related to loans individually evaluated; (2) quantitative reserves related to loans collectively evaluated; (3) qualitative reserves related to loans collectively evaluated; and (4) a temporal estimate is made for incurred loss emergence period for each loan category within the collectively evaluated pools.

A summary of the methodology employed on a quarterly basis with respect to each of these components in order to evaluate the overall adequacy of the Company’s allowance for loan losses is as follows:

Specific Reserve for Loans Individually Evaluated

First, the Company identifies loan relationships having aggregate balances in excess of $150 thousand with potential credit weaknesses. Such loan relationships are identified primarily through the Company’s analysis of internal loan evaluations, past due loan reports, TDRs and loans adversely classified. Each loan so identified is then individually evaluated for

impairment. Loans are considered impaired when, based on current information and events, it is probable that the Company will be unable to collect all amounts due according to the contractual terms of the original loan agreement. Substantially all impaired loans have historically been collateral dependent, meaning repayment of the loan is expected or is considered to be provided solely from the sale of the loan’s underlying collateral. For such loans, the Company measures impairment based on the fair value of the loan’s collateral, which is generally determined utilizing current appraisals. A specific reserve is established in an amount equal to the excess, if any, of the recorded investment in each impaired loan over the fair value of its underlying collateral, less estimated costs to sell. The Company’s policy is to re-evaluate the fair value of collateral dependent loans at least every twelve months unless there is a known deterioration in the collateral’s value, in which case a new appraisal is obtained.

Purchase credit impaired (“PCI”) loans are collectively evaluated, but are not included in the general reserve as described below. The evaluation of the PCI loans requires continued quarterly assessment of key assumptions and estimates similar to the initial fair value estimate, including changes in the severity of loss, timing and speed of payments, collateral value changes, expected cash flows and other relevant factors. The quarterly assessment is compared to the initial fair value estimate and a determination is made if an adjustment to the allowance for loan loss is deemed necessary.

Quantitative Reserve for Loans Collectively Evaluated

Second, the Company stratifies the loan portfolio into two general business loan pools: substandard (7 risk rated) and pass-rated (0 to 6 rated) by loan type. Substandard rated loans are subject to higher credit loss rates in the allowance for loan loss calculation. The Company utilizes historical loss rates for commercial real estate and commercial and industrial loans assessed by internal risk rating. Historical loss rates on residential real estate and consumer loans are not risk graded. Residential real estate and consumer loans are considered as part of the pass-rated portfolio unless removed due to specific reserve evaluation based on past due status and/or other indications of credit deterioration. Quantitative reserves relative to each loan pool are established as follows: for all loan segments an allocation equaling 100% of the respective pool’s average 3-year historical net loan charge-off rate (determined based upon the most recent 12 quarters) is applied to the aggregate recorded investment in the pool of loans. Purchased performing loans are collectively evaluated as their own separate category within each loan pool.

Qualitative Reserve for Loans Collectively Evaluated

Third, the Company considers the necessity to adjust the average historical net loan charge-off rates relative to each of the above two loan pools for potential risks factors that could result in actual losses deviating from prior loss experience. Such qualitative risk factors considered are: (1) lending policies and procedures, (2) business conditions, (3) volume and nature of the loan portfolio, (4) experience, ability and depth of lending management, (5) problem loan trends, (6) quality of the Company’s loan review system, (7) concentrations in the loan portfolio, (8) competition, legal, and regulatory environment and (9) collateral coverage and loan-to-value.

Loss Emergence Period for Loans Collectively Evaluated

Fourth, the general allowance related to loans collectively evaluated includes an estimate of incurred losses over an estimated loss emergence period ("LEP"). The LEP is generated utilizing a charge-off look-back analysis, which evaluates the time from the first indication of elevated risk of repayment (or other early event indicating a problem) to eventual charge-off to support the LEP considered in the allowance calculation. This reserving methodology establishes the approximate number of months of LEP that represents incurred losses for each loan portfolio within each portfolio segment in addition to the qualitative reserves.

Credit Quality Information

Loan Origination/Risk Management: The Company has certain lending policies and procedures in place designed to maximize loan income within an acceptable level of risk. The Company’s Board of Directors reviews and approves these policies and procedures on a regular basis. A reporting system supplements the review process by providing management and the Company’s Board of Directors with frequent reports related to loan production, loan quality, concentrations of credit, loan delinquencies, non-performing loans and potential problem loans. The Company seeks to diversify the loan portfolio as a means of managing risk associated with fluctuations in economic conditions.

Credit Quality Indicators/Classified Loans: In monitoring the credit quality of the portfolio, management applies a credit quality indicator and uses an internal risk rating system to categorize commercial loans. These credit quality indicators range from one through nine, with a higher number correlating to increasing risk of loss. These ratings are used as inputs to the calculation of the allowance for loan losses. Consistent with regulatory guidelines, the Company provides for the classification of loans which are considered to be of lesser quality as special mention, substandard, doubtful, or loss (i.e. risk rated 6, 7, 8 and 9, respectively).

The following are the definitions of the Company’s credit quality indicators:

Pass: Loans the Company considers in the commercial portfolio segments that are not adversely rated, are contractually current as to principal and interest, and are otherwise in compliance with the contractual terms of the loan agreement. Management believes there is a low risk of loss related to these loans considered pass rated.

Special Mention: Loans the Company considers having some potential weaknesses, but are deemed to not carry levels of risk inherent in one of the subsequent categories, are designated as special mention. A special mention loan has potential weaknesses that deserve management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the asset or in the institution’s credit position at some future date. This might include loans which may require a higher level of supervision or internal reporting because of: (i) declining industry trends; (ii) increasing reliance on secondary sources of repayment; (iii) the poor condition of or lack of control over collateral; or (iv) failure to obtain proper documentation or any other deviations from prudent lending practices. Economic or market conditions which may, in the future, affect the obligor, may warrant special mention of the asset. Loans for which an

adverse trend in the borrower’s operations or an imbalanced position in the balance sheet which has not reached a point where the liquidation is jeopardized may be included in this classification. Special mention loans are not adversely classified and do not expose the Company to sufficient risks to warrant classification.

Substandard: Loans the Company considers as substandard are inadequately protected by the current net worth and paying capacity of the borrower or of the collateral pledged, if any. Substandard loans have a well-defined weakness that jeopardizes liquidation of the debt. Substandard loans include those loans where there is the distinct possibility of some loss of principal, if the deficiencies are not corrected.

Doubtful: Loans the Company considers as doubtful have all of the weaknesses inherent in those loans that are classified as substandard. These loans have the added characteristic of a well-defined weakness which is inadequately protected by the current sound worth and paying capacity of borrower or of the collateral pledged, if any, and calls into question the collectability of the full balance of the loan. The possibility of loss is high but because of certain important and reasonably specific pending factors which may work to the advantage and strengthening of the loan, its classification as loss is deferred until its more exact status is determined. Pending factors include proposed merger, acquisition, or liquidation procedures, capital injection, perfecting liens on additional collateral and refinancing plans. The entire amount of the loan might not be classified as doubtful when collection of a specific portion appears highly probable. Loans are generally not classified doubtful for an extended period of time (i.e., over a year).

Loss: Loans the Company considers as losses are those considered uncollectible and of such little value that their continuance as an asset is not warranted and the uncollectible amounts are charged-off. This classification does not mean the asset has absolutely no recovery or salvage value, but rather it is not practical or desirable to defer writing off this worthless asset even though partial recovery may be affected in the future. Losses are taken in the period in which they are determined to be uncollectible.

The following tables present the Company’s commercial loans by risk rating at December 31, 2020 and December 31, 2019:

On November 26, 2019, the Company executed a new Subordinated Note Purchase Agreement with an aggregate of $40.0 million of subordinated notes (the "Notes") to accredited investors. The Notes have a maturity date of December 1, 2029 and bear a fixed interest rate of 4.63% through December 1, 2024 payable semi-annually in arrears. From December 1, 2024 and thereafter the interest rate shall be reset quarterly to an interest rate per annum equal to the then current three-month Secured Overnight Financing Rate ("SOFR") plus 3.27%. The Company has the option beginning with the interest payment date of December 1, 2024, and on any scheduled payment date thereafter, to redeem the Notes, in whole or in part upon prior approval of the Federal Reserve. The transaction included debt issuance costs of $659 thousand and $700 thousand net of amortization as of December 31, 2020 and 2019 respectively, that are netted against the subordinated debt.

The Company also has $20.6 million in floating Junior Subordinated Deferrable Interest Debentures (“Debentures”) issued by NHTB Capital Trust II (“Trust II”) and NHTB Capital Trust III (“Trust III”), which are both Connecticut statutory trusts. The Debentures were issued on March 30, 2004, carry a variable interest rate of three-month LIBOR plus 2.79%, and mature in 2034. The debt is callable by the Company at the time when any interest payment is made. Trust II and Trust III are considered variable interest entities for which the Company is not the primary beneficiary. Accordingly, Trust II and Trust III are not consolidated into the Company’s financial statements.

NOTE 9. EMPLOYEE BENEFIT PLANS

Pension Plans

The Company maintains a legacy, employer-sponsored defined benefit pension plan (the “Plan”) for which participation and benefit accruals were frozen on January 13, 2017. The Plan was assumed in connection with a business combination in 2017. Accordingly, no employees are permitted to commence participation in the Plan and future salary increases and years of credited service are not considered when computing an employee’s benefits under the Plan. As of December 31, 2020, all minimum Employee Retirement Income Security Act (“ERISA”) funding requirements have been met. The Company did not have any defined benefit pension plans prior to 2017.

The following tables set forth information about the plan for the year ended December 31, 2020 and 2019:

Total accumulated other comprehensive loss (pre-tax) | ​ | $ | 1,071 | ​ | $ | 893

​

The after tax components of accumulated other comprehensive loss, which have not yet been recognized in net periodic pension cost, related to the Plan are a net loss of $822 thousand. The Company expects to make no cash contributions to the pension trust during the 2021 fiscal year. The amount expected to be amortized from accumulated other comprehensive loss into net periodic pension cost over the next fiscal year is zero.

The principal actuarial assumptions used at December 31, 2020 and 2019 were as follows:

​

​ | ​ | ​ | ​ | ​ | ​ | ​
​ |  | 2020 |  | ​ | 2019 |
Projected benefit obligation |  |  |  | ​ |  | ​
Discount rate |  | 2.46 | % | ​ | 3.23 | %
Net periodic pension cost | ​ | ​ | ​ | ​ | ​ | ​
Discount rate |  | 3.23 | % | ​ | 4.23 | %
Long-term rate of return on plan assets |  | 6.00 |  | ​ | 6.50 | ​

​

The discount rate that is used in the measurement of the pension obligation is determined by comparing the expected future retirement payment cash flows of the plan to the Citigroup Above Median Double-A Curve as of the measurement date. The expected long-term rate of return on Plan assets reflects expectations of future returns as applied to the plan’s target allocation of asset classes. In estimating that rate, appropriate consideration was given to historical returns earned by equities and fixed income securities.

The Company’s overall investment strategy with respect to the Plan’s assets is to maintain assets at a level that will sufficiently cover future beneficiary obligations while achieving long term growth in assets. The Plan’s targeted asset allocation is 54% equity securities and 46% fixed-income securities primarily consisting of intermediate-term products.

The fair values for investment securities are determined by quoted prices in active markets, if available (Level 1). For securities where quoted prices are not available, fair values are calculated based on market prices of similar securities (Level 2). For securities where quoted prices or market prices of similar securities are not available, fair values are calculated using discounted cash flows or other market indicators (Level 3).

401(k) Plan

The Company maintains a Section 401(k) savings plan for substantially all of its employees. Employees are eligible to participate in the 401(k) Plan on the first day of any quarter following their date of hire and attainment of age 21½ . Under the plan, the Company makes a matching contribution of a portion of the amount contributed by each participating employee, up to a percentage of the employee’s annual salary. The plan allows for supplementary profit sharing contributions by the Company, at its discretion, for the benefit of participating employees. The total expense for this plan in 2020, 2019, and 2018 was $1.2 million, $1.1 million, and $1.0 million, respectively.

Other Plans

As a result of the acquisition of a business combination in 2017, the Company assumed salary continuation agreements for supplemental retirement income with certain prior executives and senior officers along with an executive indexed supplemental retirement plan for one prior executive. The total liability for these agreements included in other liabilities was $8.8 million at December 31, 2020 and $8.1 million at December 31, 2019. Expense recorded in 2020, 2019 and 2018 under these agreements was $793 thousand, $779 thousand and $752 thousand, respectively.

The Company has determined that a valuation allowance is not required for its net deferred tax asset since it is more likely than not that this asset is realizable principally through future taxable income and future reversal of existing temporary differences.

GAAP requires the measurement of unrecorded tax benefits related to uncertain tax positions. An unrecorded tax benefit is the difference between the tax benefit of a position taken, or expected to be taken, on a tax return and the benefit recorded for accounting purposes. At December 31, 2020 and 2019, the Company had no unrecorded tax benefits and does not expect the amount of unrecorded tax benefits to significantly increase within the next twelve months.

The Company is subject to income tax in the U.S. federal jurisdiction and also in the states of Maine, New Hampshire and Massachusetts. The Company is no longer subject to examination by taxing authorities for years before 2017.

NOTE 11. DERIVATIVE FINANCIAL INSTRUMENTS AND HEDGING ACTIVITIES

The Company uses derivative instruments to minimize fluctuations in earnings and cash flows caused by interest rate volatility. The Company’s interest rate risk management strategy involves modifying the re-pricing characteristics of certain assets or liabilities so the changes in interest rates do not have a significant effect on net interest income. Thus, all of the Company's derivative contracts are considered to be interest rate contracts.

The Company recognizes its derivative instruments on the consolidated balance sheet at fair value. On the date the derivative instrument is entered into, the Company designates whether the derivative is part of a hedging relationship (i.e., cash flow or fair value hedge). The Company formally documents relationships between hedging instruments and hedged items, as well as its risk management objective and strategy for undertaking hedge transactions. The Company also assesses, both at the hedge’s inception and on an ongoing basis, whether the derivatives used in hedging transactions are highly effective in offsetting the changes in cash flows or fair values of hedged items. Changes in fair value of derivative instruments that are highly effective and qualify as cash flow hedges are recorded in other comprehensive income or loss.

105

Table of Contents

The Company offers derivative products in the form of interest rate swaps, to commercial loan customers to facilitate their risk management strategies. These instruments are executed through Master Netting Arrangements ("MNA") with financial institution counterparties or Risk Participation Agreements ("RPA") with commercial bank counterparties, for which the Company assumes a pro rata share of the credit exposure associated with a borrower’s performance related to the derivative contract with the counterparty.

Cash flow hedges

Interest rate swaps on wholesale funding

In March and November 2019 and April 2020, the Company entered into interest rate swaps on wholesale borrowings (the "SWAPS") to limit its exposure to rising interest rates over a five year term. Under the terms of the agreement, the Company has two swaps each with a $50.0 million notional amount and pay fixed interest rates of 2.46% and 1.53%, and one swap with a $25.0 million notional amount and pays a fixed interest rate of 0.59%. The financial institution counterparty pays the Company interest on the three-month LIBOR rate. The Company designated the swap as a cash flow hedge. Based on direct and indirect events resulting from COVID-19 pandemic, the Company determined that $50 million of wholesale fundings were no longer necessary. As a result of the unprecedented nature of the pandemic the FASB staff believes that it would be acceptable for a company to determine that missed forecasts related to the effects of the COVID-19 pandemic need not be considered when determining whether it has exhibited a pattern of missing forecasts that would call into question its ability to accurately predict forecasted transactions and the propriety of using cash flow hedge accounting in the future for similar transactions. The FASB staff believes that this guidance did not contemplate forecasts changing so rapidly as a result of a pandemic. The March 2019 hedge with a $50.0 million notional amount and fixed rate of 2.46% was terminated in the fourth quarter of 2020, with $3.9 million loss recognized in acquisition, conversion, and other expenses as a result of the reclassification from other comprehensive income.

Interest rate cap agreements

In 2014, interest rate cap agreements were purchased to limit the Company’s exposure to rising interest rates on four rolling, three-month borrowings indexed to three-month LIBOR. Under the terms of the agreements, the Company paid total premiums of $4.6 million for the right to receive cash flow payments if three-month LIBOR rises above the caps of 3.00%, thus effectively ensuring interest expense on the borrowings at maximum rates of 3.00% for the duration of the agreements. The interest rate cap agreements were designated as cash flow hedges, however the caps were terminated in

the fourth quarter of 2019, with $3.2 million recognized in acquisition, restructuring and other expenses as a result of the reclassification from other comprehensive income.

Fair value hedges

For derivative instruments that are designated and qualify as a fair value hedge, the gain or loss on the derivative instrument as well as the offsetting loss or gain on the hedged asset or liability attributable to the hedged risk are recognized in current earnings. The Company utilizes interest rate swaps designated as fair value hedges to mitigate the effect of changing interest rates on the fair values of fixed rate callable securities available-for-sale. The hedging strategy on securities converts the fixed interest rates to LIBOR-based variable interest rates. These derivatives are designated as partial term hedges of selected cash flows covering specified periods of time prior to the call dates of the hedged securities. During 2019, the Company entered into eight swap transactions with a notional amount of $37.2 million designated as fair value hedges. These derivatives are intended to protect against the effects of changing interest rates on the fair values of fixed rate securities. The fixed rates on the transactions have a weighted average of 1.697%.

Economic hedges

Forward sale commitments

The Company utilizes forward sale commitments on residential mortgage loans to hedge interest rate risk and the associated effects on the fair value of interest rate lock commitments and loans originated for sale. The forward sale commitments are accounted for as derivatives. The Company typically uses a combination of best efforts and mandatory delivery contracts. The contracts are loan sale agreements where the Company commits to deliver a certain principal amount of mortgage loans to an investor at a specified price on or before a specified date. Generally, the Company may enter into contracts just prior to the loan closing with a customer.

Customer loan derivatives

The Company enters into customer loan derivatives to facilitate the risk management strategies for commercial banking customers. The Company mitigates this risk by entering into equal and offsetting loan swap agreements with highly rated third-party financial institutions. The Company is party to master netting arrangements with its financial institutional counterparties and the Company offsets assets and liabilities under these arrangements for financial statement presentation purposes.

The master netting arrangements provide for a single net settlement of all loan swap agreements, as well as collateral or cash funds, in the event of default on, or termination of, any one contract with that counterparty. Collateral is provided by cash or securities received or posted by the counterparty with net liability positions, respectively, in accordance with contract thresholds. Currently, the Company has posted cash of $23.5 million with counterparties.

The below table describes the potential effect of master netting arrangements on the consolidated balance sheet and the financial collateral pledged for these arrangements:

Non-hedging derivatives

Interest rate lock commitments

The Company enters into interest rate lock commitments (“IRLCs”) for residential mortgage loans, which commit the Company to lend funds to a potential borrower at a specific interest rate and within a specified period of time. IRLCs relate to the origination of residential mortgage loans that are held for sale are considered derivative financial instruments under

110

Table of Contents

applicable accounting guidance. Outstanding IRLCs expose the Company to the risk that the price of the mortgage loans underlying the commitments may decline due to increases in mortgage interest rates from inception of the rate lock to the funding of the loan. The IRLCs are free-standing derivatives which are carried at fair value with changes recorded in non-interest income in the Company’s Consolidated Statements of Income. Changes in the fair value of IRLCs subsequent to inception are based on; (i) changes in the fair value of the underlying loan resulting from the fulfillment of the commitment and (ii) changes in the probability when the loan will fund within the terms of the commitment, which is affected primarily by changes in interest rates and the passage of time.

NOTE 12. OTHER COMMITMENTS, CONTINGENCIES, AND OFF-BALANCE SHEET ACTIVITIES

Customer Obligations

The Company is a party to financial instruments in the normal course of business to meet financing needs of its customers. These financial instruments include commitments to extend credit, unused or unadvanced loan funds, and letters of credit. The Company uses the same lending policies and procedures to make such commitments as it uses for other lending products. Customer’s creditworthiness is evaluated on a case-by-case basis.

Commitments to originate loans, including unused or unadvanced loan funds, are agreements to lend to a customer provided there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require customer payment of a fee. Since many of the commitments are expected to expire without being fully drawn upon, the total commitment amounts do not necessarily represent future cash requirements.

Standby letters of credit are conditional commitments issued by the Company to guarantee the performance of a customer to a third party. Standby letters of credit generally become payable upon the failure of the customer to perform according to the terms of the underlying contract with the third party, while commercial letters of credit are issued specifically to facilitate commerce and typically result in the commitment being drawn on when the underlying transaction is consummated between the customer and a third party. The contractual amount of these letters of credit represents the maximum potential future payments guaranteed by the Company. Typically these letters of credit expire if unused; therefore the total amounts do not necessarily represent future cash requirements.

The following table summarizes the contractual amounts of commitments and contingent liabilities to customers as of December 31, 2020 and December 31, 2019:

Legal Claims

Various legal claims arise from time to time in the normal course of business. As of December 31, 2020, neither the Company nor its subsidiaries were involved in any pending legal proceedings believed by management to be material to the Company’s financial condition or results of operations. Periodically, there have been various claims and lawsuits involving the Company, such as claims to enforce liens, condemnation proceedings on properties in which the Company holds security interests, claims involving the making and servicing of real property loans, and other issues incident in the normal course of the Company’s business. However, neither the Company nor its subsidiaries are a party to any pending legal proceedings that it believes, in the aggregate, would have a material adverse effect on the financial condition or operations of the Company. Additionally, an estimate of future, probable losses cannot be estimated as of December 31, 2020.

At each date shown, the Company and the Bank met the conditions to be classified as “well-capitalized” under the relevant regulatory framework. To be categorized as “well-capitalized”, an institution must maintain minimum total risk-based, Tier 1 risk-based, and Tier 1 leverage ratios as set forth in the table above.

The Company and the Bank are subject to the Basel III rule that requires the Company and the Bank to assess their Common equity tier 1 capital to risk weighted assets and the Company and the Bank each exceed the minimum to be “well-capitalized.” Effective January 1, 2019, all banking organizations must maintain a minimum Common equity tier 1 risk-based capital ratio of 7.0%, a minimum Tier 1 risk-based capital ratio of 8.5% and a minimum Total risk- based capital ratio of 10.5%.

NOTE 14. STOCK BASED COMPENSATION PLANS

On October 3, 2000, the shareholders of the Company approved the Bar Harbor Bankshares and Subsidiaries Incentive Stock Option Plan of 2000 (the “ISOP”) for its officers and employees, which provided for the issuance of up to 1,012,500 shares of common stock. The purchase price of the stock covered by each option must be at least 100% of the trading value on the date such option was granted. Vesting terms ranged from three to seven years. According to the ISOP no option shall be granted after October 3, 2010, ten years after the effective date of the ISOP.

On May 19, 2015, the shareholders of the Company approved the adoption of the 2015 Bar Harbor Bankshares and Subsidiaries Equity Incentive Plan (the “2015 Plan”) for employees and directors of the Company and its subsidiaries. Subject to adjustment for stock splits, stock dividends, and similar events, the total number of shares of common stock that could be issued under the 2015 Plan over the 10 year period in which the plan is in place was 420,000 shares of common stock. The 2015 Plan was administered by the Company’s Compensation Committee. All employees and directors of the Company and its subsidiaries were eligible to participate in the 2015 Plan, subject to the discretion of the administrator and the terms of the 2015 Plan. The maximum stock award granted to one individual did not exceed 30,000 shares of common stock (subject to adjustment for stock splits, and similar events) for any calendar year. No grants were made after May 19, 2019 pursuant to this plan.

On May 21, 2019 the shareholders of the Company approved the adoption of the 2019 Bar Harbor Bankshares and Subsidiaries Equity Incentive Plan (the “2019 Plan”) for employees and directors of the Company and its subsidiaries. Subject to adjustment for stock splits, stock dividends, and similar events, the total number of shares of common stock that can be issued under the 2019 Plan over the 10 year period in which the plan will be in place is 500,000 shares of common stock. The 2019 Plan is administered by the Company’s Compensation Committee. All employees and directors of the Company and its subsidiaries are eligible to participate in the 2019 Plan, subject to the discretion of the administrator and the terms of the 2019 Plan. As of December 31, 2020 there were 330,188 shares available for grant under this plan.

In April of 2013, the Board of Directors approved a Long Term Incentive Program for senior management members. The program is designed to be made up of a series of three year rolling plans utilizing the shares made available through the approved equity plans. Grants may be given in time vested restricted stock awards, time vested restricted stock units or performance vested restricted stock units, or a combination of these types of grants.

Compensation expense recognized in connection with the stock based compensation plans are presented in the following table for the years ended December 31, 2020, 2019, and 2018:

NOTE 15. FAIR VALUE MEASUREMENTS

A description of the valuation methodologies used for assets and liabilities measured at fair value, as well as the general classification of such instruments pursuant to the valuation hierarchy, is set forth below. These valuation methodologies were applied to all of the Company’s financial assets and financial liabilities that are carried at fair value.

Securities Available for Sale: All securities and major categories of securities classified as available for sale are reported at fair value utilizing Level 2 inputs. For these securities, the Company obtains fair value measurements from independent pricing providers. The fair value measurements used by the pricing providers consider observable data that may include dealer quotes, market maker quotes and live trading systems. If quoted prices are not readily available, fair values are determined using matrix pricing models, or other model-based valuation techniques requiring observable inputs other than quoted prices such as market pricing spreads, credit information, callable features, cash flows, the U.S. Treasury yield curve, trade execution data, market consensus prepayment speeds, default rates, and the securities’ terms and conditions, among other things.

Derivative Assets and Liabilities

Cash Flow Hedges. The valuation of the Company’s cash flow hedges are obtained from a third party. The pricing analysis is based on observable inputs for the contractual terms of the derivatives, including the period to maturity and interest rate curves. The inputs used to value the Company’s cash flow hedges are all classified as Level 2 measurements.

Interest Rate Lock Commitments. The Company enters into IRLCs for residential mortgage loans, which commit the Company to lend funds to a potential borrower at a specific interest rate and within a specified period of time. The estimated fair value of commitments to originate residential mortgage loans for sale is based on quoted prices for similar loans in active markets. However, this value is adjusted by a factor which considers the likelihood of a loan in a lock position will ultimately close. The closing ratio is derived from the Company’s internal data and is adjusted using significant management judgment. As such, IRLCs are classified as Level 3 measurements.

Forward Sale Commitments. The Company utilizes forward sale commitments as economic hedges against potential changes in the values of the IRLCs and loans originated for sale. The fair values of the Company’s delivery loan sale commitments are determined similarly to the IRLCs using quoted prices in the market place that are observable. However, closing ratios included in the calculation are internally generated and are based on management’s judgment and prior experience, which are not considered observable factors. As such, mandatory delivery forward commitments are classified as Level 3 measurements.

Customer Loan Derivatives. The valuation of the Company’s customer loan derivatives is obtained from a third-party pricing service and is determined using a discounted cash flow analysis on the expected cash flows of each derivative. The pricing analysis is based on observable inputs for the contractual terms of the derivatives, including the period to maturity and interest rate curves. The Company incorporates credit valuation adjustments to appropriately reflect both its own nonperformance risk and the respective counterparty’s nonperformance risk in the fair value measurements. In adjusting the fair value of its derivative contracts for the effect of nonperformance risk, the Company has considered the impact of master netting arrangements and any applicable credit enhancements, such as collateral postings.

Although the Company has determined that the majority of the inputs used to value its customer loan derivatives fall within Level 2 of the fair value hierarchy, the credit valuation adjustments associated with its derivatives utilize Level 3 inputs, such as estimates of current credit spreads to evaluate the likelihood of default by itself and its counterparties. However, as of December 31, 2020, the Company assessed the significance of the impact of the credit valuation adjustments on the overall valuation of its derivative positions and determined that the credit valuation adjustments are not significant to the overall valuation of its derivatives. As a result, the Company determined that its derivative valuations in their entirety are classified in Level 2 of the fair value hierarchy.

The table below presents the changes in Level 3 assets and liabilities that were measured at fair value on a recurring basis in 2020 and 2019.

There were no Level 1 or Level 2 non-recurring fair value measurements for the periods ended December 31, 2020 and December 31, 2019.

Impaired Loans. Loans are generally not recorded at fair value on a recurring basis. Periodically, the Company records non-recurring adjustments to the carrying value of loans based on fair value measurements for partial charge-offs of the uncollectible portions of those loans. Non-recurring adjustments can also include certain impairment amounts for collateral-dependent loans calculated when establishing the allowance for credit losses. Such amounts are generally based on the fair value of the underlying collateral supporting the loan and, as a result, the carrying value of the loan less the calculated valuation amount does not necessarily represent the fair value of the loan. Real estate collateral is typically valued using appraisals or other indications of value based on recent comparable sales of similar properties or assumptions generally observable in the marketplace. However, the choice of observable data is subject to significant judgment, and there are often adjustments based on judgment in order to make observable data comparable and to consider the impact of time, the condition of properties, interest rates, and other market factors on current values. Additionally, commercial real estate appraisals frequently involve discounting of projected cash flows, which relies inherently on unobservable data. Therefore, non-recurring fair value measurement adjustments that relate to real estate collateral have generally been classified as Level 3. Estimates of fair value for other collateral that supports commercial loans are generally based on assumptions not observable in the marketplace and therefore such valuations have been classified as Level 3.

Capitalized loan servicing rights. A loan servicing right asset represents the amount by which the present value of the estimated future net cash flows to be received from servicing loans exceed adequate compensation for performing the servicing. The fair value of servicing rights is estimated using a present value cash flow model. The most important assumptions used in the valuation model are the anticipated rate of the loan prepayments and discount rates. Adjustments are only recorded when the discounted cash flows derived from the valuation model are less than the carrying value of the asset. Although some assumptions in determining fair value are based on standards used by market participants, some are based on unobservable inputs and therefore are classified in Level 3 of the valuation hierarchy.

Other real estate owned (“OREO”). OREO results from the foreclosure process on residential or commercial loans issued by the Bank. Upon assuming the real estate, the Company records the property at the fair value of the asset less the estimated sales costs. Thereafter, OREO properties are recorded at the lower of cost or fair value less the estimated sales costs. OREO fair values are primarily determined based on Level 3 data including sales comparables and appraisals.

Premises held for sale. Premises held for sale, identified as part of the Company’s strategic review and branch optimization exercise, were transferred from premises and equipment at the lower of amortized cost or fair value less the estimated sales costs. Assets held for sale fair values are primarily determined based on Level 3 data including sales comparables and appraisals.

Summary of Estimated Fair Values of Financial Instruments

Trust Management Fees

The trust management business generates revenue through a range of fiduciary services including trust and estate administration, wealth advisory, and investment management to individuals, businesses, not-for-profit organizations, and municipalities. Revenue from these services is generally recognized over time and is typically based on a time elapsed

measure of progress. Certain fees, such as bill paying fees, distribution fees, real estate sale fees, and supplemental tax service fees, are recorded as revenue at a point in time upon the completion of the service.

Financial Services Fees

Bar Harbor Financial Services is a branch office of Infinex, an independent registered broker dealer offering securities and insurance products not affiliated with the Company or its subsidiaries. The Company has a revenue sharing agreement with Infinex for any financial service fee income generated. Financial services fees are recognized at a point in time upon the completion of monthly service requirements.

Interchange Fees

The Company earns interchange fees from transaction fees that merchants pay whenever a customer uses a debit card to make a purchase from the merchant. The fees are paid to the card-issuing bank to cover handling costs, fraud, bad debt costs and the risk involved in approving the payment. Interchange fees are generally recognized as revenue at a point in time upon the completion of a debit card transaction.

Customer Deposit Fees

The Customer Deposit business offers a variety of deposit accounts with a range of interest rates, fee schedules and other terms, which are designed to meet the customer’s financial needs. Additional depositor related services provided to customers include ATM, bank-by-phone, internet banking, internet bill pay, mobile banking, and other cash management services which include remote deposit capture, ACH origination, and wire transfers. These customer deposit fees are generally recognized by the Company at a point in time upon the completion of the service.

Other Customer Service Fees

The Company has certain incentive and referral fee arrangements with independent third parties in which fees are earned for new account activity, product sales, or transaction volume generated for the respective third parties. The Company also earns a percentage of the fees generated from third party credit card plans promoted through the Bank. Revenue from these incentive and referral fee arrangements are recognized over time using the right to invoice measure of progress.

Contract Balances with Customers

The following table provides information about contract assets or receivables and contract liabilities or deferred revenues from contracts with customers.

​

​ | ​ | ​ | ​ | ​ | ​ | ​
​ |  | ​ |  | ​
(in thousands) | ​ | December 31, 2020 | ​ | December 31, 2019

Other Assets | ​ | $ | 1,121 | ​ | $ | 1,703
Other Liabilities | ​ |  | 2,785 | ​ |  | 3,114

​

The timing of revenue recognition, billings and cash collections results in contract assets or receivables and contract liabilities or deferred revenue on the consolidated balance sheets. For most customer contracts, fees are deducted directly from customer accounts and, therefore, there is no associated impact on the accounts receivable balance. For certain types of service contracts, the Company has an unconditional right to consideration under the service contract and an accounts receivable balance is recorded for services completed. When consideration is received, or such consideration is unconditionally due, from a customer prior to transferring goods or services to the customer under the terms of a contract, a contract liability is recorded. Contract liabilities are recognized as revenue after control of the products or services is transferred to the customer and all revenue recognition criteria have been met.

Costs to Obtain and Fulfill a Contract

The Company currently expenses contract costs for processing and administrative fees for debit card transactions. The Company also expenses custody fees and transactional costs associated with securities transactions as well as third party tax preparation fees. The Company has elected the practical expedient in ASC 340-40-25-4, whereby the Company recognizes the incremental costs of obtaining contracts as an expense when incurred if the amortization period of the assets the Company otherwise would have recognized is one year or less.

NOTE 17. LEASES

A lease is defined as a contract, or part of a contract, that conveys the right to control the use of identified property, plant or equipment for a period of time in exchange for consideration. On January 1, 2019, the Company adopted ASU No. 2016-02 “Leases” and all subsequent ASUs modifying ASC 842. Substantially all of the leases pursuant to which the Company is the lessee are comprised of real estate property for branches, ATM locations, and office space with terms extending through 2040. All leases are classified as operating leases, and therefore, were previously not recognized on the Company’s consolidated balance sheets. With the adoption of ASC 842, operating lease agreements are required to be recognized on the consolidated balance sheets as a right- of-use (“ROU”) asset with a corresponding lease liability using the modified retrospective approach.

The Company has elected the following practical expedients in conjunction with implementation of ASC 842 as follows:

● | Package of practical expedients:

| o | Lease classification as an operating lease under the prior standards is grandfathered.

| o | Re-evaluation of embedded leases evaluated under the prior standards is not required.

| o | No re-assessment of previously recorded initial direct lease costs.

● | Election to exclude short-term leases (i.e., leases with initial terms of twelve months or less), from capitalization on the consolidated balance sheets.

​

The following table presents the consolidated statements of condition classification of the Company’s ROU assets and lease liabilities:

​

​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
(in thousands) |  | Classification |  | December 31, 2020 |  | December 31, 2019
Lease Right-of-Use Assets |  | ​ | ​ | ​ |  | ​ | ​ |
Operating lease right-of-use assets |  | Other assets | ​ | $ | 10,338 | ​ | $ | 9,623
​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
Lease Liabilities |  |  | ​ |  |  | ​ |  |
Operating lease liabilities |  | Other liabilities | ​ |  | 10,627 | ​ |  | 9,651

​

The calculated amount of the ROU assets and lease liabilities in the table above are impacted by the length of the lease term and the discount rate used for the present value of the minimum lease payments. The Company’s lease agreements often include one or more options to renew at the Company’s discretion. If at lease inception, the Company considers the exercising of a renewal option to be reasonably certain, the Company will include the extended term in the calculation of the ROU asset and lease liability. Regarding the discount rate, ASC 842 requires the use of the rate implicit in the lease whenever this rate is readily determinable. As this rate is rarely determinable, the Company utilizes its incremental borrowing rate at lease inception, on a collateralized basis, over a similar term. For operating leases existing prior to January 1, 2019, the rate for the original lease term as of January 1, 2019 was used.

​

​ | ​ | ​ | ​ | ​ | ​ | ​
​ |  | December 31, 2020 |  | December 31, 2019
Weighted-average remaining lease term (in years) | ​ |  | ​ | ​ |  | ​
Operating leases | ​ | 9.26 | ​ | ​ | 8.96 | ​
​ | ​ | ​ | ​ | ​ | ​ | ​
Weighted-average discount rate | ​ |  | ​ | ​ |  | ​
Operating leases | ​ | 3.15 | % | ​ | 3.27 | %

​

The following table represents lease costs and other lease information. As the Company elected, for all classes of underlying assets, not to separate lease and non-lease components and instead to account for them as a single lease component, the variable lease cost primarily represents variable payments such as real estate taxes, common area maintenance and utilities.

ITEM 9A. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures: The Company carried out an evaluation, under the supervision and with the participation of management, including the Chief Executive Officer and Chief Financial Officer, of the effectiveness of its disclosure controls and procedures as of the end of the period covered by this report. Based upon that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that the disclosure controls and procedures are designed to ensure that the information required to be disclosed in the reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms and are operating in an effective manner.

Management Report on Internal Control over Financial Reporting: Management of the Company is responsible for establishing and maintaining adequate internal control over financial reporting. Internal control over financial reporting as defined in Rule 13a-15(f) and 15d-15(f) under the Exchange Act is a process designed by, or under the supervision of, the Company’s principal executive and principal financial officers and effected by the Company’s Board of Directors, management and other personnel 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 and includes those policies and procedures that:

| ● | Pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of the assets of the Company;

| ● | 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

| ● | 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.

Management assessed the effectiveness of the Company’s internal control over financial reporting as of December 31, 2020. In making this assessment, management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”) in Internal Control-Integrated Framework (2013).

Based on its assessment, management believes that as of December 31, 2020, the Company’s internal control over financial reporting is effective, based on the criteria set forth by COSO in Internal Control – Integrated Framework (2013).

The Company’s independent registered public accounting firm has issued an audit report on the effectiveness of the Company’s internal control over financial reporting. This audit report appears within Item 8 of this Annual Report on Form 10-K.

Changes in Internal Control Over Financial Reporting: No change in the internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) occurred during the last fiscal year that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Shareholders and the Board of Directors of Bar Harbor Bankshares and Subsidiaries:

Opinion on the Internal Control Over Financial Reporting

We have audited Bar Harbor Bankshares and Subsidiaries’ (the Company) internal control over financial reporting as of December 31, 2020, 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, 2020, 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 balance sheets as of December 31, 2020 and 2019, 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, 2020, and the related notes to the consolidated financial statements of the Company and our report dated March 10, 2021, 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 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.
