Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Use of Estimates In preparing the Consolidated Financial Statements in conformity with GAAP, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the balance sheets and income and expenses for the periods reported. Actual results could differ from those estimates based on changing conditions, including economic conditions and future events. Material estimates that are particularly susceptible to change relate to the determination of the allowance for loan losses, valuation and fair value measurements, other-than-temporary impairment on investment securities, the liabilities for benefit obligations (particularly pensions), the provision for income taxes and impairment of goodwill and other intangibles. Cash and Cash Equivalents Cash and cash equivalents include cash on hand and amounts due from banks, federal funds sold, and other short-term investments including restricted cash pledged, all of which have an original maturity of 90 days or less. Cash and cash equivalents includes $21.3 million and $49.2 million of restricted cash pledged as collateral at December 31, 2021 and 2020, respectively, which for purposes of the Company’s consolidated statements of cash flows, is included in cash, cash equivalents and restricted cash. Securities Debt securities are classified at the time of purchase as either “trading,” “available for sale” or “held to maturity.” Equity securities are measured at fair value with changes in the fair value recognized through net income. Debt securities that are bought and held principally for the purpose of resale in the near term are classified as trading securities and recorded at fair value, with subsequent changes in fair value included in net income. Debt securities that the Company has the positive intent and the ability to hold to maturity are classified as held to maturity securities and recorded at amortized cost. Debt securities not classified as either trading or held to maturity are classified as available for sale and recorded at fair value, with changes in fair value excluded from net income and reported in other comprehensive income, net of related tax. Amortization of premiums and accretion of discounts are computed using the effective interest rate method. Management evaluates impaired securities for other-than-temporary impairment (“OTTI”) at least on a quarterly basis, and more frequently when economic or market concerns warrant such evaluation. Consideration is given to the length of time and the extent to which the fair value has been less than cost, current market conditions, the financial condition and near-term prospects of the issuer, performance of collateral underlying the securities, the ratings of the individual securities, the interest rate environment, the Company’s intent to sell the security or whether it is more likely than not that the Company will be required to sell the debt security before its anticipated recovery, as well as other qualitative factors. If a decline in fair value below the amortized cost basis of an investment is judged to be other than temporary, the investment is written down to fair value. The portion of the impairment related to credit losses is included in net income, and the portion of the impairment related to other factors is included in other comprehensive income. Gains and losses on sales of securities are recognized at the time of sale on the specific-identification basis. Loans Loans are reported at their principal amount outstanding, net of deferred loan fees and any unearned discount or unamortized premium for acquired loans. Unearned discount and unamortized premium are accreted and amortized, respectively, to interest and dividend income on a basis that results in level rates of return over the terms of the loans. For originated loans, origination fees and related direct incremental origination costs are offset, and the resulting net amount is deferred and amortized over the life of the related loans using the effective interest method, assuming a certain level of prepayments. When loans are sold or repaid, the unamortized fees and costs are recorded to interest and dividend income. Interest income on loans is accrued based upon the daily principal amount outstanding except for loans on non-accrual status. For acquired loans with no signs of credit deterioration at acquisition, interest income is also accrued based upon the daily principal amount outstanding, adjusted further by the accretion of any discount or amortization of any premium associated with the loan. Non-performing Loans (“NPLs”) Non-accrual Loans Interest accruals are generally discontinued when management has determined that the borrower may be unable to meet contractual obligations and/or when loans are 90 days or more past due. Exceptions may be made if management believes that collateral held by the Company is clearly sufficient and in full satisfaction of both principal and interest or the loan is accounted for as a purchased credit-impaired loan. When a loan is placed on non-accrual, all interest previously accrued but not collected is reversed against current period income and amortization of deferred loan fees is discontinued. Interest received on non-accrual loans is either applied against principal or reported as income according to management’s judgment as to the collectability of principal. Non-accrual loans may be returned to an accrual status when principal and interest payments are no longer delinquent, and the risk characteristics of the loan have improved to the extent that there no longer exists a concern as to the collectability of principal and interest. Loans are considered past due based upon the number of days delinquent according to their contractual terms. Non-accrual loans and loans that are more than 90 days past due but still accruing interest are considered NPLs. Impaired Loans Impaired loans consist of all loans for which management has determined it is probable the Company will be unable to collect all amounts due according to the contractual terms of the loan agreements. Factors considered by management in determining impairment include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due. The Company measures impairment of loans using a discounted cash flow method, the loan’s observable market price, or the fair value of the collateral if the loan is collateral dependent. Troubled Debt Restructured (“TDR”) Loans In cases where a borrower experiences financial difficulties and the Company makes certain concessionary modifications to contractual terms, the loan is classified as a TDR. Modifications may include adjustments to interest rates, extensions of maturity, consumer loans where the borrower’s obligations have been effectively discharged through Chapter 7 bankruptcy and the borrower has not reaffirmed the debt to the Company, and other actions intended to minimize economic loss and avoid foreclosure or repossession of collateral. All TDR loans are considered impaired and therefore are subject to a specific review for impairment loss. The impairment analysis discounts the present value of the anticipated cash flows by the loan’s contractual rate of interest in effect prior to the loan’s modification or the fair value of collateral if the loan is collateral dependent. The amount of impairment loss, if any, is recorded as a specific loss allocation to each individual loan in the allowance for loan losses. Commercial loans (commercial and industrial, commercial real estate, commercial construction, and business banking loans) and residential loans that have been classified as TDRs and which subsequently default are reviewed to determine if the loan should be deemed collateral dependent. In such an instance, any shortfall between the value of the collateral and the book value of the loan is determined by measuring the recorded investment in the loan against the fair value of the collateral less costs to sell. The Company’s policy is to retain any restructured loans, which are on non-accrual status prior to being modified, on non-accrual status for approximately six months subsequent to being modified before the Company considers its return to accrual status. If the restructured loan is on accrual status prior to being modified, the Company reviews it to determine if the modified loan should remain on accrual status. Purchased Credit-impaired (“PCI”) Loans At acquisition, loans that have evidence of deterioration in credit quality since origination and for which it is probable that all contractually required payments will not be collected are initially recorded at fair value with no valuation allowance. Such loans are deemed to be PCI loans. Under the accounting model for PCI loans, the excess of cash flows expected to be collected over the carrying amount of the loans, referred to as the “accretable yield,” is accreted into interest income over the life of the loans using the effective yield method. Accordingly, PCI loans are not subject to classification as non-accrual in the same manner as originated loans. Rather, acquired loans are considered to be accruing loans because their interest income relates to the accretable yield recognized and not to contractual interest payments at the loan level. The difference between contractually required principal and interest payments and the cash flows expected to be collected, referred to as the “non-accretable difference,” includes estimates of both the impact of prepayments and future credit losses expected to be incurred over the life of the loans. The estimate of cash flows expected to be collected is regularly re-assessed subsequent to acquisition. These re-assessments involve updates, as necessary, of the key assumptions and estimates used in the initial estimate of fair value. Generally speaking, expected cash flows are affected by: •Changes in the expected principal and interest payments over the estimated life – Changes in expected cash flows may be driven by the credit outlook and actions taken with borrowers. Changes in expected future cash flows resulting from loan modifications are included in the assessment of expected cash flows. •Change in prepayment assumptions – Prepayments affect the estimated life of the loans, which may change the amount of interest income expected to be collected. •Change in interest rate indices for variable rate loans – Expected future cash flows are based, as applicable, on the variable rates in effect at the time of the assessment of expected cash flows. A decrease in expected cash flows in subsequent periods may indicate that the loan is impaired which would require the establishment of an allowance for loan losses by a charge to the provision for loan losses. An increase in expected cash flows in subsequent periods serves, first, to reduce any previously established allowance for loan losses by the increase in the present value of cash flows expected to be collected, and results in a recalculation of the amount of accretable yield for the loan. The adjustment of accretable yield due to an increase in expected cash flows is accounted for as a change in estimate. The additional cash flows expected to be collected are reclassified from the non-accretable difference to the accretable yield, and the amount of periodic accretion is adjusted accordingly over the remaining life of the loans. A PCI loan may be resolved either through receipt of payment (in full or in part) from the borrower, the sale of the loan to a third party, or foreclosure of the collateral. For PCI loans accounted for on an individual loan basis and resolved directly with the borrower, any amount received from resolution in excess of the carrying amount of the loan is recognized and reported within interest income. A refinancing or modification of a PCI loan accounted for individually is assessed to determine whether the modification represents a TDR. If the loan is considered to be a TDR, it will be included in the total impaired loans reported by the Company. The loan will continue to recognize interest income based upon the excess of cash flows expected to be collected over the carrying amount of the loan. Allowance for Loan Losses The allowance for loan losses is established to provide for probable losses incurred in the Company’s loan portfolio at the balance sheet date and is established through a provision for loan losses charged to net income. The allowance is based on management’s assessment of many factors, including the risk characteristics of the loan portfolio, current economic conditions, and trends in loan delinquencies and charge-offs. Charge-offs, net of recoveries, are charged directly to the allowance. Commercial and residential loans are charged-off in the period in which they are deemed uncollectible. Delinquent loans in these product types are subject to ongoing review and analysis to determine if a charge-off in the current period is appropriate. For consumer finance loans, policies and procedures exist that require charge-off consideration upon a certain triggering event depending on the product type. Charge-off triggers include: 120 days delinquent for automobile, home equity, and other consumer loans with the exception of cash reserve loans for which the trigger is 150 days delinquent; death of the borrower; or Chapter 7 bankruptcy. In addition to those events, the charge-off determination includes other loan quality indicators, such as collateral position and adequacy or the presence of other repayment sources. The allowance for loan losses is evaluated on a regular basis by management. While management uses current information in establishing the allowance for losses, future adjustments to the allowance may be necessary if economic conditions or conditions relative to borrowers differ substantially from the assumptions used in making the evaluation. Management uses a methodology to systematically estimate the amount of loss incurred in the portfolio. The Company’s commercial real estate, commercial and industrial, commercial construction and business banking loans are evaluated using a loan rating system, historical losses and other factors which form the basis for estimating incurred losses. Homogeneous populations of loans, including residential mortgages and consumer loans, are analyzed as groups taking into account delinquency ratios, historical loss experience and charge-offs. The allowance consists of specific and general components. The specific component consists of reserves for impaired loans (defined as those where management has determined it is probable it will not collect all payments when due), typically classified as either doubtful or substandard. For impaired loans, an allowance is established when the discounted cash flows (or collateral value or observable market price) of the loan is lower than the carrying value of the loan. The general component covers non-impaired, non-classified loans and is based on the Company’s historical loss experience adjusted for qualitative factors, including internal infrastructure factors, external macroeconomic factors, internal portfolio factors and external industry data, all customized to loan pools that include loans with similar characteristics. In the ordinary course of business, the Company enters into commitments to extend credit and standby letters of credit. Such financial instruments are recorded in the financial statements when they become payable. The credit risk associated with these commitments is evaluated in a manner similar to the allowance for loan losses. The reserve for unfunded lending commitments is included in other liabilities in the balance sheet. Additionally, various regulatory agencies, as an integral part of the Company’s examination process, periodically assess the appropriateness of the allowance for loan losses and may require the Company to increase its provision for loan losses or recognize further loan charge-offs, in accordance with GAAP. Mortgage Banking Activities Mortgage loans held for sale to the secondary market are carried at the lower of cost or estimated market value on an individual loan basis. The Company enters into commitments to fund residential mortgage loans with an offsetting forward commitment to sell them in the secondary markets in order to mitigate interest rate risk. Gains or losses on sales of mortgage loans are recognized in the consolidated statements of income at the time of sale. Interest income is recognized on loans held for sale between the time the loan is funded and the loan is sold. Direct loan origination costs and fees are deferred upon origination and are recognized in the consolidated statements of income on the date of sale. Other Real Estate Owned OREO consists of properties and other assets acquired through foreclosure proceedings or acceptance of a deed in lieu of foreclosure. OREO is recorded in other assets in the consolidated balance sheets, on an individual asset basis at the fair value less estimated costs to sell on the date we obtain control. Any write-downs to the cost of the related asset upon transfer to OREO to reflect the asset at fair value less estimated costs to sell is recorded through the allowance for loan losses. The Company relies primarily on third-party valuation information from certified appraisers and values are generally based upon recent appraisals of the underlying collateral, brokers’ opinions based upon recent sales of comparable properties, estimated equipment auction or liquidation values, income capitalization, or a combination of income capitalization and comparable sales. As of December 31, 2021 and 2020, the Company’s OREO was immaterial. Federal Home Loan Bank Stock The Company, as a member of the Federal Home Loan Bank (“FHLB”) of Boston (“FHLBB”), is required to maintain an investment in capital stock of the FHLB. Based on redemption provisions, the stock has no quoted market value and is carried at cost. Premises and Equipment Land is carried at cost. Buildings, leasehold improvements and equipment are stated at cost less accumulated depreciation and amortization. Depreciation is computed using the straight-line method over the estimated useful lives of the related assets. Leasehold improvements are amortized over the shorter of the lease terms or the estimated lives of the improvements. Expected lease terms include lease options to the extent that the exercise of such options is reasonably assured. Banking premises and equipment held for sale are carried at the lower of cost or estimated fair value, less estimated costs to sell. Goodwill and Other Intangible Assets Acquisitions of businesses are accounted for using the acquisition method of accounting. Accordingly, the net assets of the companies acquired are recorded at their fair values at the date of acquisition. Goodwill represents the excess of purchase price over the fair value of net assets acquired. Other intangible assets represent acquired assets that lack physical substance but can be distinguished from goodwill because of contractual or other legal rights, or because the asset is capable of being sold or exchanged either on its own, or in combination with a related contract, asset, or liability. The Company evaluates goodwill for impairment at least annually, during the third quarter, or more often if warranted, using a quantitative impairment approach. The quantitative impairment test compares the book value to the fair value of each reporting unit. If the book value exceeds the fair value, an impairment is charged to net income. Management has identified two reporting units for purposes of testing goodwill for impairment: the banking business and the insurance agency business. Other intangible assets, all of which are definite-lived, are stated at cost less accumulated amortization. The Company evaluates other intangible assets for impairment whenever events or changes in circumstances indicate that the carrying value of the asset may not be fully recovered. The Company considers factors including, but not limited to, changes in legal factors and business climate that could affect the value of the intangible asset. Any impairment losses are charged to net income. The Company amortizes other intangible assets over their respective estimated useful lives. The estimated useful lives of core deposit identifiable intangible assets fall within a range of seven to ten years and the estimated useful life of customer lists from insurance agency acquisitions is ten years. The estimated useful life of non-compete agreements resulting from insurance agency acquisitions are dependent upon the terms of the agreement. The Company reassesses the useful lives of other intangible assets at least annually, or more frequently based on specific events or changes in circumstances. Retirement Plans The Company provides benefits to its employees and executive officers through various retirement plans, including a defined benefit plan, a defined benefit supplemental executive retirement plan, a defined contribution plan, a benefit equalization plan, and an outside directors’ retainer continuance plan. Effective November 1, 2020, the defined benefit plan (“Defined Benefit Plan”) and the benefit equalization plan (“BEP”) were amended to convert the plans from a traditional final average earnings plan design to a cash balance plan design. Benefits earned under the final average earnings plan design were frozen at October 31, 2020. Starting November 1, 2020, future benefits are earned under the cash balance plan design. The defined benefit plan benefits are provided through membership in the Savings Banks Employees’ Retirement Association (“SBERA”). The Defined Benefit Plan is a noncontributory, defined benefit plan. Under the final average earnings plan design, benefits became fully vested after three years of eligible service for individuals employed on or before October 31, 1989. For individuals employed subsequent to October 31, 1989 and who were already in the Defined Benefit Plan as of November 1, 2020, benefits became fully vested after five years of eligible service. Under the cash balance plan design and for employees who were not already in the Defined Benefit Plan as of November 1, 2020, benefits become fully vested after three years of eligible service. The annual contribution to the Defined Benefit Plan is based upon standards established by the Pension Protection Act. The contribution is based on an actuarial method intended to provide not only for benefits attributable to service to date, but also for those expected to be earned in the future. The Company also has an unfunded Defined Benefit Supplemental Executive Retirement Plan (“DB SERP”) that provides certain retired and currently employed officers with defined pension benefits in excess of qualified plan limits imposed by U.S. federal tax law. The DB SERP has a plan year end of December 31. The Company’s BEP, which is an unfunded plan, provides retirement benefits to certain employees whose retirement benefits under the Defined Benefit Plan are limited per the Internal Revenue Code. The BEP has a plan year end of October 31. The Company also has an unfunded Outside Directors’ Retainer Continuance Plan (“ODRCP”) that provides pension benefits to outside directors who retire from service. The Outside Directors’ Retainer Continuance Plan has a plan year end of December 31. Effective December 31, 2020, the Company closed the ODRCP to new participants and froze benefit accruals for active participants. Plan assets are invested in various investment funds and held at fair value which generally represents observable market prices. Pension liability is determined based on the actuarial cost method factoring in assumptions such as salary increases, expected retirement date, mortality rate, and employee turnover. The actuarial cost method used to compute the pension liabilities and related expense is the projected unit credit method. The projected benefit obligation is principally determined based on the present value of the projected benefit distributions at an assumed discount rate (which is the rate at which the projected benefit obligation could be effectively settled as of the measurement date). The discount rate which is utilized is determined using the spot rate approach whereby the individual spot rates on the Financial Times and Stock Exchange (“FTSE”) above-median yield curve are applied to each corresponding year’s projected cash flow used to measure the respective plan’s service cost and interest cost. Periodic pension expense (or income) includes service costs, interest costs based on the assumed discount rate, the expected return on plan assets, if applicable, based on the market value of assets and amortization of actuarial gains and losses. Net period benefit cost excluding service cost is included within other noninterest expense in the consolidated statements of income. Service cost for all plans except the ODRCP is included in salaries and employee benefits in the consolidated statements of income. Service cost for the ODRCP is included in professional services in the consolidated statements of income. The amortization of actuarial gains and losses for the DB SERP and ODRCP is determined using the 10% corridor minimum amortization approach and is taken over the average remaining future service of the plan participants for the ODRCP, and over the average remaining future life expectancy of plan participants for the DB SERP. The amortization of actuarial gains and losses for the Defined Benefit Plan and BEP is determined without using the 10% corridor minimum amortization approach and is taken over the average remaining future service of the plan participants. The overfunded or underfunded status of the plans is recorded as an asset or liability on the consolidated balance sheets, with changes in that status recognized through other comprehensive income, net of related taxes. Funded status represents the difference between the projected benefit obligation of the plan and the market value of the plan’s assets. Employee Tax Deferred Incentive Plan The Company has an employee tax deferred incentive plan (“401(k) plan”) under which the Company makes voluntary contributions within certain limitations. All employees who meet specified age and length of service requirements are eligible to participate in the 401(k) plan. The amount contributed by the Company is included in salaries and employee benefits expense. Defined Contribution Supplemental Executive Retirement Plan The Company has a defined contribution supplemental executive retirement plan (“DC SERP”), which allows certain senior officers to earn benefits calculated as a percentage of their compensation. The participant benefits are adjusted based upon a deemed investment performance of measurement funds selected by the participant. These measurement funds are for tracking purposes and are used only to track the performance of a mutual fund, market index, savings instrument, or other designated investment or portfolio of investments. Effective December 31, 2021, the Company closed the DC SERP to new participants and froze benefit accruals for active participants. Deferred Compensation The Company sponsors three plans which allow for elective compensation deferrals by directors, former trustees, and certain senior-level employees. Each plan allows its participants to designate deemed investments for deferred amounts from certain options which include diversified choices, such as exchange traded funds and mutual funds. Portfolios with various risk profiles are available to participants with the approval of the Compensation Committee. The Company purchases and sells investments which track the deemed investment choices, so that it has available funds to meet its payment liabilities. Deferred amounts, adjusted for deemed investment performance, are paid at the time of a participant designated date or event, such as separation from service, death, or disability. The total amounts due to participants under these plans are included in other liabilities on the Company’s consolidated balance sheets. Employee Stock Ownership Plan (“ESOP”) ESOP shares are shown as a reduction of equity and are presented in the consolidated statements of shareholders’ equity as unallocated common stock held by ESOP. Compensation expense for the Company’s ESOP is recorded at an amount equal to the shares committed to be allocated by the ESOP multiplied by the average fair market value of the shares during the year. The Company recognizes compensation expense ratably over the year based upon the Company’s estimate of the number of shares committed to be allocated by the ESOP. When the shares are released, unallocated common stock held by ESOP is reduced by the cost of the ESOP shares released and the difference between the average fair market value and the cost of the shares committed to be allocated by the ESOP is recorded as an adjustment to additional paid-in capital. The loan receivable from the ESOP is not reported as an asset nor is the Company’s guarantee to fund the ESOP reported as a liability on the Company’s consolidated balance sheet. Share-Based Compensation The Company measures share-based compensation on the grant date fair value on a straight-line basis over the vesting period during which an employee is required to provide services in exchange for the award; the requisite service period. The Company uses various pricing models to estimate the fair value of stock awards granted. The Company measures the fair value of the restricted stock using the closing market price of the Company’s common stock on the date of grant. The Company records compensation expense equal to the grant date fair value of the Company’s restricted stock with a corresponding increase in equity. Reductions in compensation expense associated with forfeited awards are accounted for as incurred. Upon vesting, the fair value of the award in excess of recorded expense is recognized as a component of income tax expense. Variable Interest Entities (“VIE”) and Voting Interest Entities (“VOE”) The Company is involved in the normal course of business with various types of special purpose entities, some of which meet the definition for VIEs and VOEs. VIEs are entities that possess any of the following characteristics: 1) the total equity investment at risk is insufficient to permit the legal entity to finance its activities without additional subordinated financial support from other parties; 2) as a group, the holders of the equity investment at risk lack any of the characteristics of a controlling financial interest; or 3) the equity investors’ voting rights are not proportional to the economics, and substantially all of the activities of the entity either involve or are conducted on behalf of an investor that has disproportionately few voting rights. The Company consolidates entities deemed to be VIEs when it, or a wholly-owned subsidiary, is determined to be the primary beneficiary. The primary beneficiary analysis is a qualitative analysis based on power and economics. An enterprise has a controlling financial interest in a VIE if it has both 1) the power to direct the activities of a VIE that most significantly impact the VIE’s economic performance and 2) the obligation to absorb losses of the VIE that potentially could be significant to the VIE or the right to receive benefits from the VIE that potentially could be significant to the VIE. VOEs are entities in which the total equity investment at risk is sufficient to enable the entity to finance itself independently and provides the equity holders with the obligation to absorb losses, the right to receive residual returns and the right to make decisions about the entity’s activities. The Company generally consolidates VOEs when it, or a wholly-owned subsidiary, holds the majority of the voting interest in the VOE. Rabbi Trusts The Company established rabbi trusts to meet its obligations under certain executive non-qualified retirement benefits and deferred compensation plans and to mitigate the expense volatility of the aforementioned retirement plans. The rabbi trusts are considered VIEs as the equity investment at risk is insufficient to permit the trust to finance its activities without additional subordinated financial support from the Company. The Company is considered the primary beneficiary of the rabbi trusts as it has the power to direct the activities of the rabbi trusts that significantly affect the rabbi trust’s economic performance and it has the obligation to absorb losses of the rabbi trusts that could potentially be significant to the rabbi trusts by virtue of its contingent call options on the rabbi trust’s assets in the event of the Company’s bankruptcy. As the primary beneficiary of these VIEs, the Company consolidates the rabbi trust investments. In general, the rabbi trust investments and any earnings received thereon are accumulated, reinvested and used exclusively for trust purposes. These rabbi trust investments consist primarily of cash and cash equivalents, U.S. government agency obligations, equity securities, mutual funds and other exchange-traded funds, and are recorded at fair value in the Company’s consolidated balance sheet. Changes in fair value are recorded in noninterest income in the statements of income. These rabbi trust assets are included within other assets in the Company’s consolidated balance sheet. Tax Credit Investment Through a wholly-owned subsidiary, the Company is the sole member of a tax credit investment company through which it consolidates a community development entity (“CDE”) that is considered a VIE. The CDE is considered a VIE because as a group, the holders of the equity investment at risk lack any of the characteristics of a controlling financial interest. The tax credit investment company is considered the primary beneficiary of the CDE as it has the power to direct the activities of a VIE that most significantly impact the VIEs economic performance and the obligation to absorb losses of and the right to receive benefits from the VIE that potentially could be significant to the VIE. Bank Owned Life Insurance The Company holds bank-owned life insurance on the lives of certain participating executives, primarily as a result of mergers and acquisitions. The amount reported as an asset on the balance sheet is the sum of the cash surrender values reported to the Company by the various insurance carriers. Certain policies are split-dollar life insurance policies whereby the Company recognizes a liability for the postretirement benefit related to the arrangement. This postretirement benefit is included in other liabilities on the balance sheet. Income Taxes The Company accounts for income taxes under the asset and liability method. Under this method, deferred tax assets and liabilities are established for the temporary differences between the accounting basis and the tax basis of the Company’s assets and liabilities at enacted tax rates expected to be in effect when the amounts related to such temporary differences are realized or settled. A valuation allowance is established if it is considered more likely than not that all or a portion of the deferred tax assets will not be realized. Interest and penalties paid on the underpayment of income taxes are classified as income tax expense. The Company periodically evaluates the potential uncertainty of its tax positions as to whether it is more likely than not its position would be upheld upon examination by the appropriate taxing authority. A tax position that meets the more-likely-than-not recognition threshold is measured to determine the amount of benefit to recognize in the Consolidated Financial Statements. The tax position is measured at the largest amount of benefit that management believes is greater than 50% likely of being realized upon settlement. Low Income Housing Tax Credits and Other Tax Credit Investments As part of its community reinvestment initiatives, the Company primarily invests in qualified affordable housing projects in addition to other tax credit investment projects. The Company receives low-income housing tax credits, investment tax credits, rehabilitation tax credits, solar tax credits and other tax credits as a result of its investments in these limited partnership investments. The Company accounts for its investments in qualified affordable housing projects using the proportional amortization method and amortizes the initial cost of the investment in proportion to the tax credits and other tax benefits allocated to the Company. The amortization of the excess of the carrying amount of the investment over its estimated residual value is included as a component of income tax expense. At investment inception, the Company records a liability for the committed amount of the investment; this liability is reduced as contributions are made. The Company evaluates investments in tax credit investment companies for consolidation based on the variable or voting interest entity guidance, as appropriate. Other tax credit investment projects are accounted for using either the cost method or equity method. Advertising Costs All advertising costs are expensed in the period in which they are incurred. Advertising costs were not significant for any periods presented. Insurance Commissions Through Eastern Insurance Group LLC, the Company acts as an agent in offering property, casualty, and life and health insurance to both consumer and commercial customers. Insurance commissions consist of the several types of insurance revenue related to insurance policy sales. The Company earns a fixed commission on the sale of these insurance products and services and may occasionally earn a bonus commission if certain volume thresholds are met. The Company recognizes insurance commission revenues as performance obligations of underlying agreements are satisfied, which is typically the effective date of the insurance policy. Additionally, for certain types of insurance products, the Company may earn and recognize revenue related to the annual residual commissions commensurate with annual premiums being paid. The Company’s contracts typically contain a single, material distinct performance obligation, therefore the Company does not estimate standalone selling prices as the entire transaction price is allocated to the single performance obligation. The Company also earns profit sharing revenue from insurers whom they place into business. Such revenues are considered performance bonuses based upon certain performance metrics. This amount can vary from period to period and is difficult to predict. Therefore, the Company does not recognize revenue until it has concluded that a significant revenue reversal will not occur in future periods. Trust Operations The Bank is a full-service trust company that provides a wide range of trust services to customers that includes managing customer investments, safekeeping customer assets, supplying disbursement services, and providing other fiduciary services. Trust assets held in a fiduciary or agency capacity for customers are not included in the accompanying consolidated balance sheets as they are not assets of the Company. The fees charged are variable based on various factors such as the Company’s responsibility, the type of account, and account size. Revenue from administrative and management activities associated with these assets is recognized as performance obligations of underlying agreements are satisfied. Derivative Financial Instruments Derivative instruments are carried at fair value in the Company’s financial statements. The accounting for changes in the fair value of a derivative instrument is determined by whether it has been designated and qualifies as part of a hedging relationship, and further, by the type of hedging relationship. At the inception of a hedge, the Company documents certain items, including, but not limited to, the following: the relationship between hedging instruments and hedged items, the Company’s risk management objectives, hedging strategies, and the evaluation of hedge transaction effectiveness. Documentation includes linking all derivatives that are designated as hedges to specific assets or liabilities on the balance sheet or to specific forecasted transactions. The Company’s derivative instruments that are designated and qualify for hedge accounting are classified as cash flow hedges (i.e., hedging the exposure to variability in expected future cash flows associated with a recognized asset or liability, or a forecasted transaction). As such, changes in the fair value of the designated hedging instrument that is included in the assessment of hedge effectiveness are recorded in other comprehensive income and reclassified into net income in the same period or periods during which the hedged forecasted transaction affects net income. Such reclassifications shall be presented in the same income statement line item as the net income effect of the hedged item. If the hedging instrument is not highly effective at achieving offsetting cash flows attributable to the revised contractually specified interest rate(s), hedge accounting will be discontinued. At that time, accumulated other comprehensive income would be frozen and amortized, as long as the forecasted transactions are still probable of occurring. If a cash flow hedge is terminated, hedge accounting treatment would be retained, and accumulated other comprehensive income would be frozen and amortized, as long as the forecasted transactions are still probable of occurring. The Company’s derivative instruments not designated as hedging instruments are recorded at fair value and changes in fair value are recognized in other noninterest income. Derivative instruments not designated as hedging instruments include interest rate swaps, foreign exchange contracts offered to commercial customers to assist them in meeting their financing and investing objectives for their risk management purposes, and risk participation agreements entered into as financial guarantees of performance on customer-related interest rate swap derivatives. The interest rate and foreign exchange risks associated with customer interest rate swaps and foreign exchange contracts are mitigated by entering into similar derivatives having offsetting terms with correspondent bank counterparties. All derivative financial instruments eligible for clearing are cleared through the Chicago Mercantile Exchange (“CME”). In accordance with its amended rulebook, CME legally characterizes variation margin payments made to and received from the CME as settlement of derivatives rather than as collateral against derivatives. Fair Value Measurements ASC 820 “Fair Value Measurements and Disclosures” (“ASC 820”) defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants on the measurement date. A fair value measurement assumes that the transaction to sell the asset or transfer the liability occurs in the principal market for the asset or liability or, in the absence of a principal market, the most advantageous market. An orderly transaction is a transaction that assumes exposure to the market for a period prior to the measurement date. Market participants are buyers and sellers in the principal market that are independent, knowledgeable, able and willing to transact. ASC 820 also establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements), and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy are described below: Level 1 – Inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date. Level 2 – Valuations based on quoted prices in markets that are not active or for which all significant inputs are observable, either directly or indirectly. Level 3 – Prices or valuations that require unobservable inputs that reflect the Company’s own assumptions that are significant to the fair value measurement. To the extent that valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires more judgment. Accordingly, the degree of judgment exercised by the Company in determining fair value is greatest for instruments categorized in Level 3. A financial instrument’s level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. Leases The Company leases certain office space and equipment under various non-cancelable operating leases, some of which have renewal options to extend lease terms. At lease inception, the Company evaluates the lease terms to determine if the lease should be classified as an operating lease or a finance lease and recognizes a right of use (“ROU”) asset and corresponding lease liability. The Company makes the decision on whether to renew an option to extend a lease by considering various factors. The Company will recognize an adjustment to its ROU asset and lease liability when lease agreements are amended and executed. The discount rate used in determining the present value of lease payments is based on the Company’s incremental borrowing rate for borrowings with terms similar to each lease at commencement date. The Company has lease agreements with lease and non-lease components, which are generally accounted for as a single lease component. The Company has elected the short-term lease recognition exemption for all leases that qualify. Common Share Repurchases Shares repurchased by the Company under our share repurchase program have been classified as authorized but unissued shares. The cost of shares repurchased by the Company has been accounted for as a reduction to common stock and additional paid in capital balances. Massachusetts state law calls for repurchased shares to be classified as authorized but unissued shares. U.S. GAAP states that the accounting for share repurchases shall conform to state law where applicable. Earnings Per Share Basic earnings per share represents income available to common shareholders divided by the weighted-average number of common shares outstanding during the period. Unallocated ESOP shares are not deemed outstanding for earnings per share calculations. ESOP shares committed to be released are considered to be outstanding for purposes of the earnings per share computation. ESOP shares that have not been legally released, but that relate to employee services rendered during an accounting period (interim or annual) ending before the related debt service payment is made, are considered committed to be released. Diluted earnings per share reflects additional common shares that would have been outstanding if dilutive potential common shares had been issued, as well as any adjustment to income that would result from the assumed issuance. Potential common shares that may be issued by the Company relate to outstanding stock awards and are determined using the treasury stock method. 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 (“CODM”) in deciding how to allocate resources and evaluate performance. The Company has determined that its CODM is its President and Chief Executive Officer. The Company has two reportable segments: its banking business, which consists of a full range of banking lending, savings, and small business offerings, and its wealth management and trust operations; and its insurance agency business, which consists of insurance-related activities. Recent Accounting Pronouncements Until December 31, 2021, the Company had qualified as an emerging growth company under the Jumpstart Our Business Act of 2012 (“JOBS Act”) and had elected to defer the adoption of new or revised accounting standards until the nonpublic company effective dates. Relevant standards that were recently issued but not yet adopted as of December 31, 2021: In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting (“ASU 2020-04”). This update addresses optional expedients and exceptions for applying GAAP to certain contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. The new guidance applies only to contracts, hedging relationships, and other transactions that reference the London Interbank Offered Rate (“LIBOR”) or another reference rate expected to be discontinued because of reference rate reform. The expedients and exceptions provided by the amendments do not apply to contract modifications made and hedging relationships existing as of December 31, 2022, that an entity has elected certain optional expedients for and that are retained through the end of the hedging relationship. For public and nonpublic entities, the guidance is effective as of March 12, 2020 through December 31, 2022 and does not apply to contract modifications made after December 31, 2022. The Company will adopt this standard on the nonpublic company effective date and is currently in the process of reviewing its contracts and existing processes in order to assess the risks and potential impact of the transition away from LIBOR. As of December 31, 2021, there has been no material impact from reference rate discontinuation. In June 2016, the FASB issued ASU 2016-13, Financial Instruments–Credit Losses on Financial Instruments and relevant amendments (Topic 326) (“ASU 2016-13”). This update was created to replace the current GAAP method of calculating credit losses. Specifically, the standard replaces the existing incurred loss impairment guidance by requiring immediate recognition of expected credit losses. For financial assets carried at amortized cost that are held at the reporting date (including trade and other receivables, loans and commitments, held-to-maturity debt securities and other financial assets), credit losses are measured based on historical experience, current conditions and reasonable supportable forecasts. The standard also amends existing impairment guidance for available for sale securities, in which credit losses will be recorded as an allowance versus a write-down of the amortized cost basis of the security. It will also allow for a reversal of impairment loss when the credit of the issuer improves. The guidance requires a cumulative effect of the initial application to be recognized in retained earnings at the date of initial application. In November 2018, the FASB issued ASU 2018-19, Codification Improvements to Topic 326, Financial Instruments – Credit Losses (“Update 2018-19”). The amendments in Update No. 2018-19 were intended to clarify that receivables arising from operating leases are not within the scope of Subtopic 326-20. Instead, impairment of receivables arising from operating leases should be accounted for in accordance with Topic 842, Leases. In November 2019, the FASB issued ASU 2019-11, Codification Improvements to Topic 326, Financial Instruments – Credit Losses. This update requires entities to include expected recoveries of the amortized cost basis previously written off or expected to be written off in the valuation account for purchased financial assets with credit deterioration. In addition, the amendments in this update clarify and improve various aspects of the guidance for ASU 2016-13. For public entities that meet the definition of an SEC filer (excluding smaller reporting entities) the guidance is effective for annual reporting periods beginning after December 15, 2019. Early adoption is permitted for all entities as of the fiscal years beginning after December 15, 2018. For all other entities, the guidance is effective for annual reporting periods beginning after December 15, 2022, including interim periods within those fiscal years. On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”) was enacted in response to the COVID-19 pandemic in the United States to provide economic relief measures including the option to defer adoption of ASU 2016-13 to the earlier of the ending of the national emergency declaration related to the COVID-19 crisis or December 31, 2020. On December 27, 2020, the Consolidated Appropriations Act (the “Appropriations Act”) was enacted to fund the federal government through their fiscal year, extend certain expiring tax provisions and provide additional emergency relief to individuals and businesses related to the COVID-19 pandemic in the United States. Included within the provisions of the Appropriations Act is an extension of the adoption date for ASU 2016-13 from December 31, 2020 to the earlier of January 1, 2022 or 60 days after the date on which the COVID-19 national emergency terminates. The Company deferred adoption of this standard to January 1, 2022. On January 1, 2022, the Company adopted ASU 2016-13 using the modified retrospective method for all financial assets measured at amortized cost and off-balance sheet credit exposures. For purchased credit-deteriorated (“PCD”) financial assets that were previously classified as purchased-credit impaired (“PCI”) and accounted for under ASC 310-30, the Company adopted ASU 2016-13 using the prospective transition approach. Accordingly, the Company did not assess whether PCI assets met the criteria of PCD assets as of the date of adoption. To address the impact of ASU 2016-13, the Company formed a committee, including the Chief Credit Officer, the Chief Financial Officer, and Chief Information Officer, to assist in identifying, implementing, and evaluating the impact of the required changes to loan loss estimation models and processes. Additionally, a third party was engaged to assist the Company in project management, documentation, model governance and related internal controls implementation. As of December 31, 2021, the Company has evaluated portfolio segmentation and is finalizing model validation, model calibration, qualitative factors, new disclosures, formal policies and procedures, and other governance and control enhancements. For regulatory capital purposes, the Company has elected to delay certain effects of the adoption of ASU 2016-13 on regulatory capital for two years, followed by a three-year transition period during which it will phase-in, over a period of three years, the day-one regulatory capital effects of adoption of ASU 2016-13 in accordance with the federal banking agencies interim final rule issued in March 2020. In October 2021, the FASB issued ASU 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers (“ASU 2021-08”). This update modifies how an acquiring entity measures contract assets and contract liabilities of an acquiree in a business combination in accordance with Topic 606. The amendments in this update require the acquiring entity in a business combination to account for revenue contracts as if they had originated the contract and assess how the acquiree accounted for the contract under Topic 606. ASU 2021-08 improves comparability of recognition and measurement of revenue contracts with customers both before and after a business combination. For public business entities, the amendments in this update are effective for fiscal years beginning after December 15, 2022. For all other entities, the amendments are effective for fiscal years beginning after December 15, 2023. The amendments in this update should be applied prospectively to business combinations occurring on or after the effective date of the amendments with early adoption permitted. The Company expects the adoption of this standard will not have a material impact on its consolidated financial statements. Relevant standards that were adopted during the year ended December 31, 2021: In August 2018, the FASB issued ASU 2018-14, Compensation—Retirement Benefits—Defined Benefit Plans—General (Subtopic 715-20) Disclosure Framework—Changes to the Disclosure Requirements for Defined Benefit Plans (“ASU 2018-14”). This update modifies the disclosure requirements for employers that sponsor defined benefit pension and/or other postretirement benefit plans. The guidance eliminates requirements for certain disclosures that are no longer considered cost beneficial and requires new ones that the FASB considers pertinent. For public companies, ASU 2018-14 is effective for fiscal years ending after December 15, 2020. For nonpublic companies, ASU 2018-14 is effective for fiscal years ending after December 15, 2021. The adoption of this standard on December 31, 2021 did not have a material impact on the Company's consolidated financial statements. In August 2018, the FASB issued ASU 2018-15, Intangibles–Goodwill and Other–Internal-use software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That is a Service Contract (“ASU 2018-15”). This update addresses accounting for fees paid by a customer for implementation, set-up and other upfront costs incurred in a cloud computing arrangement that is hosted by the vendor (i.e., a service contract). The new guidance aligns treatment for capitalization of implementation costs with guidance on internal-use software. For public entities, the guidance is effective for annual reporting periods beginning after December 15, 2019. For nonpublic entities, the guidance is effective for annual reporting periods beginning after December 15, 2020, and for all interim periods beginning after December 15, 2021. The adoption of this standard on January 1, 2021 did not have a material impact on the Company's consolidated financial statements. In January 2021, the FASB issued ASU 2021-01, Reference Rate Reform (Topic 848) (“ASU 2021-01”) which expands the scope of guidance in ASC 848 so that companies can apply the optional expedients to derivative instruments affected by the clearing house changes. ASU 2021-01 also clarifies and updates several items in ASU 2020-04 as part of the FASB’s monitoring of global reference rate reform activities. ASU 2021-01 permits entities to elect certain optional expedients and exceptions to modifications of interest rate indexes used for computing when accounting derivative contracts and certain hedging relationships impacted by changes in interest rates used for discounting, margining, or contract price alignment. ASU 2021-01 clarifies other aspects of the guidance in ASC 848 and provides new guidance on how to address the effects of the cash compensation adjustment that is provided as part of the above change on certain aspects of hedge accounting. The guidance was effective upon issuance and allows for retrospective or prospective application with certain conditions. The Company did not elect retrospective application. Changes made in connection with the adoption of this update did not have a material impact on the Company’s consolidated financial statements.

Summary of Significant Accounting Policies

In preparing the Consolidated Financial Statements in conformity with GAAP, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the balance sheets and income and expenses for the periods reported. Actual results could differ from those estimates based on changing conditions, including economic conditions and future events. Material estimates that are particularly susceptible to change relate to the determination of the allowance for loan losses, valuation and fair value measurements, other-than-temporary impairment on investment securities, the liabilities for benefit obligations (particularly pensions), the provision for income taxes and impairment of goodwill and other intangibles.

Cash and Cash Equivalents

Cash and cash equivalents include cash on hand and amounts due from banks, federal funds sold, and other short-term investments including restricted cash pledged, all of which have an original maturity of 90 days or less. Cash and cash equivalents includes $21.3 million and $49.2 million of restricted cash pledged as collateral at December 31, 2021 and 2020, respectively, which for purposes of the Company’s consolidated statements of cash flows, is included in cash, cash equivalents and restricted cash.

Debt securities are classified at the time of purchase as either “trading,” “available for sale” or “held to maturity.” Equity securities are measured at fair value with changes in the fair value recognized through net income. Debt securities that are bought and held principally for the purpose of resale in the near term are classified as trading securities and recorded at fair value, with subsequent changes in fair value included in net income. Debt securities that the Company has the positive intent and the ability to hold to maturity are classified as held to maturity securities and recorded at amortized cost.

Debt securities not classified as either trading or held to maturity are classified as available for sale and recorded at fair value, with changes in fair value excluded from net income and reported in other comprehensive income, net of related tax. Amortization of premiums and accretion of discounts are computed using the effective interest rate method.

Management evaluates impaired securities for other-than-temporary impairment (“OTTI”) at least on a quarterly basis, and more frequently when economic or market concerns warrant such evaluation. Consideration is given to the length of time and the extent to which the fair value has been less than cost, current market conditions, the financial condition and near-term prospects of the issuer, performance of collateral underlying the securities, the ratings of the individual securities, the interest rate environment, the Company’s intent to sell the security or whether it is more likely than not that the Company will be required to sell the debt security before its anticipated recovery, as well as other qualitative factors.

If a decline in fair value below the amortized cost basis of an investment is judged to be other than temporary, the investment is written down to fair value. The portion of the impairment related to credit losses is included in net income, and the portion of the impairment related to other factors is included in other comprehensive income. Gains and losses on sales of securities are recognized at the time of sale on the specific-identification basis.

Loans are reported at their principal amount outstanding, net of deferred loan fees and any unearned discount or unamortized premium for acquired loans. Unearned discount and unamortized premium are accreted and amortized, respectively, to interest and dividend income on a basis that results in level rates of return over the terms of the loans. For originated loans, origination fees and related direct incremental origination costs are offset, and the resulting net amount is deferred and amortized over the life of the related loans using the effective interest method, assuming a certain level of prepayments. When loans are sold or repaid, the unamortized fees and costs are recorded to interest and dividend income. Interest income on loans is accrued based upon the daily principal amount outstanding except for loans on non-accrual status. For acquired loans with no signs of credit deterioration at acquisition, interest income is also accrued based upon the daily principal amount outstanding, adjusted further by the accretion of any discount or amortization of any premium associated with the loan.

Non-performing Loans (“NPLs”)

Interest accruals are generally discontinued when management has determined that the borrower may be unable to meet contractual obligations and/or when loans are 90 days or more past due. Exceptions may be made if management believes that collateral held by the Company is clearly sufficient and in full satisfaction of both principal and interest or the loan is accounted for as a purchased credit-impaired loan. When a loan is placed on non-accrual, all interest previously accrued but not collected is reversed against current period income and amortization of deferred loan fees is discontinued. Interest received on non-accrual loans is either applied against principal or reported as income according to management’s judgment as to the collectability of principal. Non-accrual loans may be returned to an accrual status when principal and interest payments are no longer delinquent, and the risk characteristics of the loan have improved to the extent that there no longer exists a concern as to the collectability of principal and interest. Loans are considered past due based upon the number of days delinquent according to their contractual terms. Non-accrual loans and loans that are more than 90 days past due but still accruing interest are considered NPLs.

Impaired loans consist of all loans for which management has determined it is probable the Company will be unable to collect all amounts due according to the contractual terms of the loan agreements. Factors considered by management in determining impairment include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due. The Company measures impairment of loans using a discounted cash flow method, the loan’s observable market price, or the fair value of the collateral if the loan is collateral dependent.

Troubled Debt Restructured (“TDR”) Loans

In cases where a borrower experiences financial difficulties and the Company makes certain concessionary modifications to contractual terms, the loan is classified as a TDR. Modifications may include adjustments to interest rates, extensions of maturity, consumer loans where the borrower’s obligations have been effectively discharged through Chapter 7 bankruptcy and the borrower has not reaffirmed the debt to the Company, and other actions intended to minimize economic loss and avoid foreclosure or repossession of collateral. All TDR loans are considered impaired and therefore are subject to a specific review for impairment loss. The impairment analysis discounts the present value of the anticipated cash flows by the loan’s contractual rate of interest in effect prior to the loan’s modification or the fair value of collateral if the loan is collateral dependent. The amount of impairment loss, if any, is recorded as a specific loss allocation to each individual loan in the allowance for loan losses. Commercial loans (commercial and industrial, commercial real estate, commercial construction, and business banking loans) and residential loans that have been classified as TDRs and which subsequently default are reviewed to determine if the loan should be deemed collateral dependent. In such an instance, any shortfall between the value of the collateral and the book value of the loan is determined by measuring the recorded investment in the loan against the fair value of the collateral less costs to sell.

The Company’s policy is to retain any restructured loans, which are on non-accrual status prior to being modified, on non-accrual status for approximately six months subsequent to being modified before the Company considers its return to accrual status. If the restructured loan is on accrual status prior to being modified, the Company reviews it to determine if the modified loan should remain on accrual status.

Purchased Credit-impaired (“PCI”) Loans

At acquisition, loans that have evidence of deterioration in credit quality since origination and for which it is probable that all contractually required payments will not be collected are initially recorded at fair value with no valuation allowance. Such loans are deemed to be PCI loans. Under the accounting model for PCI loans, the excess of cash flows expected to be collected over the carrying amount of the loans, referred to as the “accretable yield,” is accreted into interest income over the life of the loans using the effective yield method. Accordingly, PCI loans are not subject to classification as non-accrual in the same manner as originated loans. Rather, acquired loans are considered to be accruing loans because their interest income relates to the accretable yield recognized and not to contractual interest payments at the loan level. The difference between contractually required principal and interest payments and the cash flows expected to be collected, referred to as the “non-accretable difference,” includes estimates of both the impact of prepayments and future credit losses expected to be incurred over the life of the loans.

The estimate of cash flows expected to be collected is regularly re-assessed subsequent to acquisition. These re-assessments involve updates, as necessary, of the key assumptions and estimates used in the initial estimate of fair value. Generally speaking, expected cash flows are affected by:

•Changes in the expected principal and interest payments over the estimated life – Changes in expected cash flows may be driven by the credit outlook and actions taken with borrowers. Changes in expected future cash flows resulting from loan modifications are included in the assessment of expected cash flows.

•Change in prepayment assumptions – Prepayments affect the estimated life of the loans, which may change the amount of interest income expected to be collected.

•Change in interest rate indices for variable rate loans – Expected future cash flows are based, as applicable, on the variable rates in effect at the time of the assessment of expected cash flows.

A decrease in expected cash flows in subsequent periods may indicate that the loan is impaired which would require the establishment of an allowance for loan losses by a charge to the provision for loan losses. An increase in expected cash flows in subsequent periods serves, first, to reduce any previously established allowance for loan losses by the increase in the present value of cash flows expected to be collected, and results in a recalculation of the amount of accretable yield for the loan. The adjustment of accretable yield due to an increase in expected cash flows is accounted for as a change in estimate. The additional cash flows expected to be collected are reclassified from the non-accretable difference to the accretable yield, and the amount of periodic accretion is adjusted accordingly over the remaining life of the loans.

A PCI loan may be resolved either through receipt of payment (in full or in part) from the borrower, the sale of the loan to a third party, or foreclosure of the collateral. For PCI loans accounted for on an individual loan basis and resolved directly with the borrower, any amount received from resolution in excess of the carrying amount of the loan is recognized and reported within interest income.

A refinancing or modification of a PCI loan accounted for individually is assessed to determine whether the modification represents a TDR. If the loan is considered to be a TDR, it will be included in the total impaired loans reported by the Company. The loan will continue to recognize interest income based upon the excess of cash flows expected to be collected over the carrying amount of the loan.

Allowance for Loan Losses

The allowance for loan losses is established to provide for probable losses incurred in the Company’s loan portfolio at the balance sheet date and is established through a provision for loan losses charged to net income. The allowance is based on management’s assessment of many factors, including the risk characteristics of the loan portfolio, current economic conditions, and trends in loan delinquencies and charge-offs. Charge-offs, net of recoveries, are charged directly to the allowance. Commercial and residential loans are charged-off in the period in which they are deemed uncollectible. Delinquent loans in these product types are subject to ongoing review and analysis to determine if a charge-off in the current period is appropriate. For consumer finance loans, policies and procedures exist that require charge-off consideration upon a certain triggering event depending on the product type. Charge-off triggers include: 120 days delinquent for automobile, home equity, and other consumer loans with the exception of cash reserve loans for which the trigger is 150 days delinquent; death of the borrower; or Chapter 7 bankruptcy. In addition to those events, the charge-off determination includes other loan quality indicators, such as collateral position and adequacy or the presence of other repayment sources.

The allowance for loan losses is evaluated on a regular basis by management. While management uses current information in establishing the allowance for losses, future adjustments to the allowance may be necessary if economic conditions or conditions relative to borrowers differ substantially from the assumptions used in making the evaluation. Management uses a methodology to systematically estimate the amount of loss incurred in the portfolio. The Company’s commercial real estate, commercial and industrial, commercial construction and business banking loans are evaluated using a loan rating system, historical losses and other factors which form the basis for estimating incurred losses. Homogeneous populations of loans, including residential mortgages and consumer loans, are analyzed as groups taking into account delinquency ratios, historical loss experience and charge-offs.

The allowance consists of specific and general components. The specific component consists of reserves for impaired loans (defined as those where management has determined it is probable it will not collect all payments when due), typically classified as either doubtful or substandard. For impaired loans, an allowance is established when the discounted cash flows (or collateral value or observable market price) of the loan is lower than the carrying value of the loan. The general component covers non-impaired, non-classified loans and is based on the Company’s historical loss experience adjusted for qualitative factors, including internal infrastructure factors, external macroeconomic factors, internal portfolio factors and external industry data, all customized to loan pools that include loans with similar characteristics.

In the ordinary course of business, the Company enters into commitments to extend credit and standby letters of credit. Such financial instruments are recorded in the financial statements when they become payable. The credit risk associated with these commitments is evaluated in a manner similar to the allowance for loan losses. The reserve for unfunded lending commitments is included in other liabilities in the balance sheet.

Additionally, various regulatory agencies, as an integral part of the Company’s examination process, periodically assess the appropriateness of the allowance for loan losses and may require the Company to increase its provision for loan losses or recognize further loan charge-offs, in accordance with GAAP.

Mortgage Banking Activities

Mortgage loans held for sale to the secondary market are carried at the lower of cost or estimated market value on an individual loan basis. The Company enters into commitments to fund residential mortgage loans with an offsetting forward commitment to sell them in the secondary markets in order to mitigate interest rate risk. Gains or losses on sales of mortgage loans are recognized in the consolidated statements of income at the time of sale. Interest income is recognized on loans held for sale between the time the loan is funded and the loan is sold. Direct loan origination costs and fees are deferred upon origination and are recognized in the consolidated statements of income on the date of sale.

Other Real Estate Owned

OREO consists of properties and other assets acquired through foreclosure proceedings or acceptance of a deed in lieu of foreclosure. OREO is recorded in other assets in the consolidated balance sheets, on an individual asset basis at the fair value less estimated costs to sell on the date we obtain control. Any write-downs to the cost of the related asset upon transfer to OREO to reflect the asset at fair value less estimated costs to sell is recorded through the allowance for loan losses. The Company relies primarily on third-party valuation information from certified appraisers and values are generally based upon recent appraisals of the underlying collateral, brokers’ opinions based upon recent sales of comparable properties, estimated equipment auction or liquidation values, income capitalization, or a combination of income capitalization and comparable sales. As of December 31, 2021 and 2020, the Company’s OREO was immaterial.

Federal Home Loan Bank Stock

The Company, as a member of the Federal Home Loan Bank (“FHLB”) of Boston (“FHLBB”), is required to maintain an investment in capital stock of the FHLB. Based on redemption provisions, the stock has no quoted market value and is carried at cost.

Premises and Equipment

Land is carried at cost. Buildings, leasehold improvements and equipment are stated at cost less accumulated depreciation and amortization. Depreciation is computed using the straight-line method over the estimated useful lives of the related assets. Leasehold improvements are amortized over the shorter of the lease terms or the estimated lives of the improvements. Expected lease terms include lease options to the extent that the exercise of such options is reasonably assured.

Banking premises and equipment held for sale are carried at the lower of cost or estimated fair value, less estimated costs to sell.

Goodwill and Other Intangible Assets

Acquisitions of businesses are accounted for using the acquisition method of accounting. Accordingly, the net assets of the companies acquired are recorded at their fair values at the date of acquisition. Goodwill represents the excess of purchase price over the fair value of net assets acquired. Other intangible assets represent acquired assets that lack physical substance but can be distinguished from goodwill because of contractual or other legal rights, or because the asset is capable of being sold or exchanged either on its own, or in combination with a related contract, asset, or liability.

The Company evaluates goodwill for impairment at least annually, during the third quarter, or more often if warranted, using a quantitative impairment approach. The quantitative impairment test compares the book value to the fair value of each reporting unit. If the book value exceeds the fair value, an impairment is charged to net income. Management has identified two reporting units for purposes of testing goodwill for impairment: the banking business and the insurance agency business.

Other intangible assets, all of which are definite-lived, are stated at cost less accumulated amortization. The Company evaluates other intangible assets for impairment whenever events or changes in circumstances indicate that the carrying value of the asset may not be fully recovered. The Company considers factors including, but not limited to, changes in legal factors and business climate that could affect the value of the intangible asset. Any impairment losses are charged to net

income. The Company amortizes other intangible assets over their respective estimated useful lives. The estimated useful lives of core deposit identifiable intangible assets fall within a range of seven to ten years and the estimated useful life of customer lists from insurance agency acquisitions is ten years. The estimated useful life of non-compete agreements resulting from insurance agency acquisitions are dependent upon the terms of the agreement. The Company reassesses the useful lives of other intangible assets at least annually, or more frequently based on specific events or changes in circumstances.

The Company provides benefits to its employees and executive officers through various retirement plans, including a defined benefit plan, a defined benefit supplemental executive retirement plan, a defined contribution plan, a benefit equalization plan, and an outside directors’ retainer continuance plan.

Effective November 1, 2020, the defined benefit plan (“Defined Benefit Plan”) and the benefit equalization plan (“BEP”) were amended to convert the plans from a traditional final average earnings plan design to a cash balance plan design. Benefits earned under the final average earnings plan design were frozen at October 31, 2020. Starting November 1, 2020, future benefits are earned under the cash balance plan design.

The defined benefit plan benefits are provided through membership in the Savings Banks Employees’ Retirement Association (“SBERA”). The Defined Benefit Plan is a noncontributory, defined benefit plan. Under the final average earnings plan design, benefits became fully vested after three years of eligible service for individuals employed on or before October 31, 1989. For individuals employed subsequent to October 31, 1989 and who were already in the Defined Benefit Plan as of November 1, 2020, benefits became fully vested after five years of eligible service. Under the cash balance plan design and for employees who were not already in the Defined Benefit Plan as of November 1, 2020, benefits become fully vested after three years of eligible service. The annual contribution to the Defined Benefit Plan is based upon standards established by the Pension Protection Act. The contribution is based on an actuarial method intended to provide not only for benefits attributable to service to date, but also for those expected to be earned in the future.

The Company also has an unfunded Defined Benefit Supplemental Executive Retirement Plan (“DB SERP”) that provides certain retired and currently employed officers with defined pension benefits in excess of qualified plan limits imposed by U.S. federal tax law. The DB SERP has a plan year end of December 31.

The Company’s BEP, which is an unfunded plan, provides retirement benefits to certain employees whose retirement benefits under the Defined Benefit Plan are limited per the Internal Revenue Code. The BEP has a plan year end of October 31.

The Company also has an unfunded Outside Directors’ Retainer Continuance Plan (“ODRCP”) that provides pension benefits to outside directors who retire from service. The Outside Directors’ Retainer Continuance Plan has a plan year end of December 31. Effective December 31, 2020, the Company closed the ODRCP to new participants and froze benefit accruals for active participants.

Plan assets are invested in various investment funds and held at fair value which generally represents observable market prices. Pension liability is determined based on the actuarial cost method factoring in assumptions such as salary increases, expected retirement date, mortality rate, and employee turnover. The actuarial cost method used to compute the pension liabilities and related expense is the projected unit credit method. The projected benefit obligation is principally determined based on the present value of the projected benefit distributions at an assumed discount rate (which is the rate at which the projected benefit obligation could be effectively settled as of the measurement date). The discount rate which is utilized is determined using the spot rate approach whereby the individual spot rates on the Financial Times and Stock Exchange (“FTSE”) above-median yield curve are applied to each corresponding year’s projected cash flow used to measure the respective plan’s service cost and interest cost. Periodic pension expense (or income) includes service costs, interest costs based on the assumed discount rate, the expected return on plan assets, if applicable, based on the market value of assets and amortization of actuarial gains and losses. Net period benefit cost excluding service cost is included within other noninterest expense in the consolidated statements of income. Service cost for all plans except the ODRCP is included in salaries and employee benefits in the consolidated statements of income. Service cost for the ODRCP is included in professional services in the consolidated statements of income. The amortization of actuarial gains and losses for the DB SERP and ODRCP is determined using the 10% corridor minimum amortization approach and is taken over the average remaining future service of the plan participants for the ODRCP, and over the average remaining future life expectancy of plan participants for the DB SERP. The amortization of actuarial gains and losses for the Defined Benefit Plan and BEP is determined without using the 10% corridor minimum amortization approach and is taken over the average remaining future service of the plan participants. The overfunded or underfunded status of the plans is recorded as an asset or liability on the consolidated balance sheets, with changes in that status recognized through other comprehensive income, net of related taxes. Funded status represents the difference between the projected benefit obligation of the plan and the market value of the plan’s assets.

Employee Tax Deferred Incentive Plan

The Company has an employee tax deferred incentive plan (“401(k) plan”) under which the Company makes voluntary contributions within certain limitations. All employees who meet specified age and length of service requirements are eligible to participate in the 401(k) plan. The amount contributed by the Company is included in salaries and employee benefits expense.

Defined Contribution Supplemental Executive Retirement Plan

The Company has a defined contribution supplemental executive retirement plan (“DC SERP”), which allows certain senior officers to earn benefits calculated as a percentage of their compensation. The participant benefits are adjusted based upon a deemed investment performance of measurement funds selected by the participant. These measurement funds are for tracking purposes and are used only to track the performance of a mutual fund, market index, savings instrument, or other designated investment or portfolio of investments. Effective December 31, 2021, the Company closed the DC SERP to new participants and froze benefit accruals for active participants.

Deferred Compensation

The Company sponsors three plans which allow for elective compensation deferrals by directors, former trustees, and certain senior-level employees. Each plan allows its participants to designate deemed investments for deferred amounts from certain options which include diversified choices, such as exchange traded funds and mutual funds. Portfolios with various risk profiles are available to participants with the approval of the Compensation Committee. The Company purchases and sells investments which track the deemed investment choices, so that it has available funds to meet its payment liabilities. Deferred amounts, adjusted for deemed investment performance, are paid at the time of a participant designated date or event, such as separation from service, death, or disability. The total amounts due to participants under these plans are included in other liabilities on the Company’s consolidated balance sheets.

Employee Stock Ownership Plan (“ESOP”)

ESOP shares are shown as a reduction of equity and are presented in the consolidated statements of shareholders’ equity as unallocated common stock held by ESOP. Compensation expense for the Company’s ESOP is recorded at an amount equal to the shares committed to be allocated by the ESOP multiplied by the average fair market value of the shares during the year. The Company recognizes compensation expense ratably over the year based upon the Company’s estimate of the number of shares committed to be allocated by the ESOP. When the shares are released, unallocated common stock held by ESOP is reduced by the cost of the ESOP shares released and the difference between the average fair market value and the cost of the shares committed to be allocated by the ESOP is recorded as an adjustment to additional paid-in capital. The loan receivable from the ESOP is not reported as an asset nor is the Company’s guarantee to fund the ESOP reported as a liability on the Company’s consolidated balance sheet.

Share-Based Compensation

The Company measures share-based compensation on the grant date fair value on a straight-line basis over the vesting period during which an employee is required to provide services in exchange for the award; the requisite service period. The Company uses various pricing models to estimate the fair value of stock awards granted. The Company measures the fair value of the restricted stock using the closing market price of the Company’s common stock on the date of grant. The Company records compensation expense equal to the grant date fair value of the Company’s restricted stock with a corresponding increase in equity. Reductions in compensation expense associated with forfeited awards are accounted for as incurred. Upon vesting, the fair value of the award in excess of recorded expense is recognized as a component of income tax expense.

Variable Interest Entities (“VIE”) and Voting Interest Entities (“VOE”)

The Company is involved in the normal course of business with various types of special purpose entities, some of which meet the definition for VIEs and VOEs.

VIEs are entities that possess any of the following characteristics: 1) the total equity investment at risk is insufficient to permit the legal entity to finance its activities without additional subordinated financial support from other parties; 2) as a group, the holders of the equity investment at risk lack any of the characteristics of a controlling financial interest; or 3) the equity investors’ voting rights are not proportional to the economics, and substantially all of the activities of the entity either involve or are conducted on behalf of an investor that has disproportionately few voting rights. The Company consolidates entities deemed to be VIEs when it, or a wholly-owned subsidiary, is determined to be the primary beneficiary. The primary beneficiary analysis is a qualitative analysis based on power and economics. An enterprise has a controlling financial interest in a VIE if it has both 1) the power to direct the activities of a VIE that most significantly impact the VIE’s

economic performance and 2) the obligation to absorb losses of the VIE that potentially could be significant to the VIE or the right to receive benefits from the VIE that potentially could be significant to the VIE.

VOEs are entities in which the total equity investment at risk is sufficient to enable the entity to finance itself independently and provides the equity holders with the obligation to absorb losses, the right to receive residual returns and the right to make decisions about the entity’s activities. The Company generally consolidates VOEs when it, or a wholly-owned subsidiary, holds the majority of the voting interest in the VOE.

The Company established rabbi trusts to meet its obligations under certain executive non-qualified retirement benefits and deferred compensation plans and to mitigate the expense volatility of the aforementioned retirement plans. The rabbi trusts are considered VIEs as the equity investment at risk is insufficient to permit the trust to finance its activities without additional subordinated financial support from the Company. The Company is considered the primary beneficiary of the rabbi trusts as it has the power to direct the activities of the rabbi trusts that significantly affect the rabbi trust’s economic performance and it has the obligation to absorb losses of the rabbi trusts that could potentially be significant to the rabbi trusts by virtue of its contingent call options on the rabbi trust’s assets in the event of the Company’s bankruptcy. As the primary beneficiary of these VIEs, the Company consolidates the rabbi trust investments. In general, the rabbi trust investments and any earnings received thereon are accumulated, reinvested and used exclusively for trust purposes. These rabbi trust investments consist primarily of cash and cash equivalents, U.S. government agency obligations, equity securities, mutual funds and other exchange-traded funds, and are recorded at fair value in the Company’s consolidated balance sheet. Changes in fair value are recorded in noninterest income in the statements of income. These rabbi trust assets are included within other assets in the Company’s consolidated balance sheet.

Tax Credit Investment

Through a wholly-owned subsidiary, the Company is the sole member of a tax credit investment company through which it consolidates a community development entity (“CDE”) that is considered a VIE. The CDE is considered a VIE because as a group, the holders of the equity investment at risk lack any of the characteristics of a controlling financial interest. The tax credit investment company is considered the primary beneficiary of the CDE as it has the power to direct the activities of a VIE that most significantly impact the VIEs economic performance and the obligation to absorb losses of and the right to receive benefits from the VIE that potentially could be significant to the VIE.

Bank Owned Life Insurance

The Company holds bank-owned life insurance on the lives of certain participating executives, primarily as a result of mergers and acquisitions. The amount reported as an asset on the balance sheet is the sum of the cash surrender values reported to the Company by the various insurance carriers. Certain policies are split-dollar life insurance policies whereby the Company recognizes a liability for the postretirement benefit related to the arrangement. This postretirement benefit is included in other liabilities on the balance sheet.

The Company accounts for income taxes under the asset and liability method. Under this method, deferred tax assets and liabilities are established for the temporary differences between the accounting basis and the tax basis of the Company’s assets and liabilities at enacted tax rates expected to be in effect when the amounts related to such temporary differences are realized or settled. A valuation allowance is established if it is considered more likely than not that all or a portion of the deferred tax assets will not be realized. Interest and penalties paid on the underpayment of income taxes are classified as income tax expense.

The Company periodically evaluates the potential uncertainty of its tax positions as to whether it is more likely than not its position would be upheld upon examination by the appropriate taxing authority. A tax position that meets the more-likely-than-not recognition threshold is measured to determine the amount of benefit to recognize in the Consolidated Financial Statements. The tax position is measured at the largest amount of benefit that management believes is greater than 50% likely of being realized upon settlement.

Low Income Housing Tax Credits and Other Tax Credit Investments

As part of its community reinvestment initiatives, the Company primarily invests in qualified affordable housing projects in addition to other tax credit investment projects. The Company receives low-income housing tax credits, investment tax credits, rehabilitation tax credits, solar tax credits and other tax credits as a result of its investments in these limited partnership investments.

The Company accounts for its investments in qualified affordable housing projects using the proportional amortization method and amortizes the initial cost of the investment in proportion to the tax credits and other tax benefits allocated to the Company. The amortization of the excess of the carrying amount of the investment over its estimated residual value is included as a component of income tax expense. At investment inception, the Company records a liability for the committed amount of the investment; this liability is reduced as contributions are made.

The Company evaluates investments in tax credit investment companies for consolidation based on the variable or voting interest entity guidance, as appropriate. Other tax credit investment projects are accounted for using either the cost method or equity method.

All advertising costs are expensed in the period in which they are incurred. Advertising costs were not significant for any periods presented.

Insurance Commissions

Through Eastern Insurance Group LLC, the Company acts as an agent in offering property, casualty, and life and health insurance to both consumer and commercial customers. Insurance commissions consist of the several types of insurance revenue related to insurance policy sales. The Company earns a fixed commission on the sale of these insurance products and services and may occasionally earn a bonus commission if certain volume thresholds are met. The Company recognizes insurance commission revenues as performance obligations of underlying agreements are satisfied, which is typically the effective date of the insurance policy. Additionally, for certain types of insurance products, the Company may earn and recognize revenue related to the annual residual commissions commensurate with annual premiums being paid. The Company’s contracts typically contain a single, material distinct performance obligation, therefore the Company does not estimate standalone selling prices as the entire transaction price is allocated to the single performance obligation.

The Company also earns profit sharing revenue from insurers whom they place into business. Such revenues are considered performance bonuses based upon certain performance metrics. This amount can vary from period to period and is difficult to predict. Therefore, the Company does not recognize revenue until it has concluded that a significant revenue reversal will not occur in future periods.

The Bank is a full-service trust company that provides a wide range of trust services to customers that includes managing customer investments, safekeeping customer assets, supplying disbursement services, and providing other fiduciary services. Trust assets held in a fiduciary or agency capacity for customers are not included in the accompanying consolidated balance sheets as they are not assets of the Company. The fees charged are variable based on various factors such as the Company’s responsibility, the type of account, and account size. Revenue from administrative and management activities associated with these assets is recognized as performance obligations of underlying agreements are satisfied.

Derivative Financial Instruments

Derivative instruments are carried at fair value in the Company’s financial statements. The accounting for changes in the fair value of a derivative instrument is determined by whether it has been designated and qualifies as part of a hedging relationship, and further, by the type of hedging relationship. At the inception of a hedge, the Company documents certain items, including, but not limited to, the following: the relationship between hedging instruments and hedged items, the Company’s risk management objectives, hedging strategies, and the evaluation of hedge transaction effectiveness. Documentation includes linking all derivatives that are designated as hedges to specific assets or liabilities on the balance sheet or to specific forecasted transactions.

The Company’s derivative instruments that are designated and qualify for hedge accounting are classified as cash flow hedges (i.e., hedging the exposure to variability in expected future cash flows associated with a recognized asset or liability, or a forecasted transaction). As such, changes in the fair value of the designated hedging instrument that is included in the assessment of hedge effectiveness are recorded in other comprehensive income and reclassified into net income in the same period or periods during which the hedged forecasted transaction affects net income. Such reclassifications shall be presented in the same income statement line item as the net income effect of the hedged item. If the hedging instrument is not highly effective at achieving offsetting cash flows attributable to the revised contractually specified interest rate(s), hedge accounting will be discontinued. At that time, accumulated other comprehensive income would be frozen and amortized, as long as the forecasted transactions are still probable of occurring. If a cash flow hedge is terminated, hedge accounting treatment would be retained, and accumulated other comprehensive income would be frozen and amortized, as long as the forecasted transactions are still probable of occurring.

The Company’s derivative instruments not designated as hedging instruments are recorded at fair value and changes in fair value are recognized in other noninterest income. Derivative instruments not designated as hedging instruments include interest rate swaps, foreign exchange contracts offered to commercial customers to assist them in meeting their financing and investing objectives for their risk management purposes, and risk participation agreements entered into as financial guarantees of performance on customer-related interest rate swap derivatives. The interest rate and foreign exchange risks associated with customer interest rate swaps and foreign exchange contracts are mitigated by entering into similar derivatives having offsetting terms with correspondent bank counterparties.

All derivative financial instruments eligible for clearing are cleared through the Chicago Mercantile Exchange (“CME”). In accordance with its amended rulebook, CME legally characterizes variation margin payments made to and received from the CME as settlement of derivatives rather than as collateral against derivatives.

Fair Value Measurements

ASC 820 “Fair Value Measurements and Disclosures” (“ASC 820”) defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants on the measurement date. A fair value measurement assumes that the transaction to sell the asset or transfer the liability occurs in the principal market for the asset or liability or, in the absence of a principal market, the most advantageous market. An orderly transaction is a transaction that assumes exposure to the market for a period prior to the measurement date. Market participants are buyers and sellers in the principal market that are independent, knowledgeable, able and willing to transact. ASC 820 also establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements), and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy are described below:

Level 1 – Inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date.

Level 2 – Valuations based on quoted prices in markets that are not active or for which all significant inputs are observable, either directly or indirectly.

Level 3 – Prices or valuations that require unobservable inputs that reflect the Company’s own assumptions that are significant to the fair value measurement.

To the extent that valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires more judgment. Accordingly, the degree of judgment exercised by the Company in determining fair value is greatest for instruments categorized in Level 3. A financial instrument’s level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement.

The Company leases certain office space and equipment under various non-cancelable operating leases, some of which have renewal options to extend lease terms. At lease inception, the Company evaluates the lease terms to determine if the lease should be classified as an operating lease or a finance lease and recognizes a right of use (“ROU”) asset and corresponding lease liability. The Company makes the decision on whether to renew an option to extend a lease by considering various factors. The Company will recognize an adjustment to its ROU asset and lease liability when lease agreements are amended and executed. The discount rate used in determining the present value of lease payments is based on the Company’s incremental borrowing rate for borrowings with terms similar to each lease at commencement date. The Company has lease agreements with lease and non-lease components, which are generally accounted for as a single lease component. The Company has elected the short-term lease recognition exemption for all leases that qualify.

Common Share Repurchases

Shares repurchased by the Company under our share repurchase program have been classified as authorized but unissued shares. The cost of shares repurchased by the Company has been accounted for as a reduction to common stock and additional paid in capital balances. Massachusetts state law calls for repurchased shares to be classified as authorized but unissued shares. U.S. GAAP states that the accounting for share repurchases shall conform to state law where applicable.

Basic earnings per share represents income available to common shareholders divided by the weighted-average number of common shares outstanding during the period. Unallocated ESOP shares are not deemed outstanding for earnings per share calculations. ESOP shares committed to be released are considered to be outstanding for purposes of the earnings per share computation. ESOP shares that have not been legally released, but that relate to employee services rendered during an

accounting period (interim or annual) ending before the related debt service payment is made, are considered committed to be released. Diluted earnings per share reflects additional common shares that would have been outstanding if dilutive potential common shares had been issued, as well as any adjustment to income that would result from the assumed issuance. Potential common shares that may be issued by the Company relate to outstanding stock awards and are determined using the treasury stock method.

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 (“CODM”) in deciding how to allocate resources and evaluate performance. The Company has determined that its CODM is its President and Chief Executive Officer. The Company has two reportable segments: its banking business, which consists of a full range of banking lending, savings, and small business offerings, and its wealth management and trust operations; and its insurance agency business, which consists of insurance-related activities.

Recent Accounting Pronouncements

Until December 31, 2021, the Company had qualified as an emerging growth company under the Jumpstart Our Business Act of 2012 (“JOBS Act”) and had elected to defer the adoption of new or revised accounting standards until the nonpublic company effective dates.

Relevant standards that were recently issued but not yet adopted as of December 31, 2021:

In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting (“ASU 2020-04”). This update addresses optional expedients and exceptions for applying GAAP to certain contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. The new guidance applies only to contracts, hedging relationships, and other transactions that reference the London Interbank Offered Rate (“LIBOR”) or another reference rate expected to be discontinued because of reference rate reform. The expedients and exceptions provided by the amendments do not apply to contract modifications made and hedging relationships existing as of December 31, 2022, that an entity has elected certain optional expedients for and that are retained through the end of the hedging relationship. For public and nonpublic entities, the guidance is effective as of March 12, 2020 through December 31, 2022 and does not apply to contract modifications made after December 31, 2022. The Company will adopt this standard on the nonpublic company effective date and is currently in the process of reviewing its contracts and existing processes in order to assess the risks and potential impact of the transition away from LIBOR. As of December 31, 2021, there has been no material impact from reference rate discontinuation.

In June 2016, the FASB issued ASU 2016-13, Financial Instruments–Credit Losses on Financial Instruments and relevant amendments (Topic 326) (“ASU 2016-13”). This update was created to replace the current GAAP method of calculating credit losses. Specifically, the standard replaces the existing incurred loss impairment guidance by requiring immediate recognition of expected credit losses. For financial assets carried at amortized cost that are held at the reporting date (including trade and other receivables, loans and commitments, held-to-maturity debt securities and other financial assets), credit losses are measured based on historical experience, current conditions and reasonable supportable forecasts. The standard also amends existing impairment guidance for available for sale securities, in which credit losses will be recorded as an allowance versus a write-down of the amortized cost basis of the security. It will also allow for a reversal of impairment loss when the credit of the issuer improves. The guidance requires a cumulative effect of the initial application to be recognized in retained earnings at the date of initial application.

In November 2018, the FASB issued ASU 2018-19, Codification Improvements to Topic 326, Financial Instruments – Credit Losses (“Update 2018-19”). The amendments in Update No. 2018-19 were intended to clarify that receivables arising from operating leases are not within the scope of Subtopic 326-20. Instead, impairment of receivables arising from operating leases should be accounted for in accordance with Topic 842, Leases. In November 2019, the FASB issued ASU 2019-11, Codification Improvements to Topic 326, Financial Instruments – Credit Losses. This update requires entities to include expected recoveries of the amortized cost basis previously written off or expected to be written off in the valuation account for purchased financial assets with credit deterioration. In addition, the amendments in this update clarify and improve various aspects of the guidance for ASU 2016-13. For public entities that meet the definition of an SEC filer (excluding smaller reporting entities) the guidance is effective for annual reporting periods beginning after December 15, 2019. Early adoption is permitted for all entities as of the fiscal years beginning after December 15, 2018. For all other entities, the guidance is effective for annual reporting periods beginning after December 15, 2022, including interim periods within those fiscal years.

On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”) was enacted in response to the COVID-19 pandemic in the United States to provide economic relief measures including the option to defer adoption of ASU 2016-13 to the earlier of the ending of the national emergency declaration related to the COVID-19 crisis or

December 31, 2020. On December 27, 2020, the Consolidated Appropriations Act (the “Appropriations Act”) was enacted to fund the federal government through their fiscal year, extend certain expiring tax provisions and provide additional emergency relief to individuals and businesses related to the COVID-19 pandemic in the United States. Included within the provisions of the Appropriations Act is an extension of the adoption date for ASU 2016-13 from December 31, 2020 to the earlier of January 1, 2022 or 60 days after the date on which the COVID-19 national emergency terminates. The Company deferred adoption of this standard to January 1, 2022.

On January 1, 2022, the Company adopted ASU 2016-13 using the modified retrospective method for all financial assets measured at amortized cost and off-balance sheet credit exposures. For purchased credit-deteriorated (“PCD”) financial assets that were previously classified as purchased-credit impaired (“PCI”) and accounted for under ASC 310-30, the Company adopted ASU 2016-13 using the prospective transition approach. Accordingly, the Company did not assess whether PCI assets met the criteria of PCD assets as of the date of adoption. To address the impact of ASU 2016-13, the Company formed a committee, including the Chief Credit Officer, the Chief Financial Officer, and Chief Information Officer, to assist in identifying, implementing, and evaluating the impact of the required changes to loan loss estimation models and processes. Additionally, a third party was engaged to assist the Company in project management, documentation, model governance and related internal controls implementation. As of December 31, 2021, the Company has evaluated portfolio segmentation and is finalizing model validation, model calibration, qualitative factors, new disclosures, formal policies and procedures, and other governance and control enhancements. For regulatory capital purposes, the Company has elected to delay certain effects of the adoption of ASU 2016-13 on regulatory capital for two years, followed by a three-year transition period during which it will phase-in, over a period of three years, the day-one regulatory capital effects of adoption of ASU 2016-13 in accordance with the federal banking agencies interim final rule issued in March 2020.

In October 2021, the FASB issued ASU 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers (“ASU 2021-08”). This update modifies how an acquiring entity measures contract assets and contract liabilities of an acquiree in a business combination in accordance with Topic 606. The amendments in this update require the acquiring entity in a business combination to account for revenue contracts as if they had originated the contract and assess how the acquiree accounted for the contract under Topic 606. ASU 2021-08 improves comparability of recognition and measurement of revenue contracts with customers both before and after a business combination. For public business entities, the amendments in this update are effective for fiscal years beginning after December 15, 2022. For all other entities, the amendments are effective for fiscal years beginning after December 15, 2023. The amendments in this update should be applied prospectively to business combinations occurring on or after the effective date of the amendments with early adoption permitted. The Company expects the adoption of this standard will not have a material impact on its consolidated financial statements.

Relevant standards that were adopted during the year ended December 31, 2021:

In August 2018, the FASB issued ASU 2018-14, Compensation—Retirement Benefits—Defined Benefit Plans—General (Subtopic 715-20) Disclosure Framework—Changes to the Disclosure Requirements for Defined Benefit Plans (“ASU 2018-14”). This update modifies the disclosure requirements for employers that sponsor defined benefit pension and/or other postretirement benefit plans. The guidance eliminates requirements for certain disclosures that are no longer considered cost beneficial and requires new ones that the FASB considers pertinent. For public companies, ASU 2018-14 is effective for fiscal years ending after December 15, 2020. For nonpublic companies, ASU 2018-14 is effective for fiscal years ending after December 15, 2021. The adoption of this standard on December 31, 2021 did not have a material impact on the Company's consolidated financial statements.

In August 2018, the FASB issued ASU 2018-15, Intangibles–Goodwill and Other–Internal-use software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That is a Service Contract (“ASU 2018-15”). This update addresses accounting for fees paid by a customer for implementation, set-up and other upfront costs incurred in a cloud computing arrangement that is hosted by the vendor (i.e., a service contract). The new guidance aligns treatment for capitalization of implementation costs with guidance on internal-use software. For public entities, the guidance is effective for annual reporting periods beginning after December 15, 2019. For nonpublic entities, the guidance is effective for annual reporting periods beginning after December 15, 2020, and for all interim periods beginning after December 15, 2021. The adoption of this standard on January 1, 2021 did not have a material impact on the Company's consolidated financial statements.

In January 2021, the FASB issued ASU 2021-01, Reference Rate Reform (Topic 848) (“ASU 2021-01”) which expands the scope of guidance in ASC 848 so that companies can apply the optional expedients to derivative instruments affected by the clearing house changes. ASU 2021-01 also clarifies and updates several items in ASU 2020-04 as part of the FASB’s monitoring of global reference rate reform activities. ASU 2021-01 permits entities to elect certain optional expedients and exceptions to modifications of interest rate indexes used for computing when accounting derivative contracts and certain hedging relationships impacted by changes in interest rates used for discounting, margining, or contract price alignment. ASU 2021-01 clarifies other aspects of the guidance in ASC 848 and provides new guidance on how to address the effects of the cash
