SUMMARY OF SIGNIFICANT ACCOUNTI

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	12 Months Ended

Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation and Consolidation The Consolidated Financial Statements (the “financial statements”) of Berkshire Hills Bancorp, Inc. and its subsidiaries (the “Company” or “Berkshire”) have been prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”). The Company is a Delaware corporation, headquartered in Boston, Massachusetts, and the holding company for Berkshire Bank (the “Bank”), a Massachusetts-chartered trust company headquartered in Pittsfield, Massachusetts. These financial statements include the accounts of the Company, its wholly-owned subsidiaries and the Bank’s consolidated subsidiaries. In consolidation, all significant intercompany accounts and transactions are eliminated. The results of operations of companies or assets acquired are included only from the dates of acquisition. All material wholly-owned and majority-owned subsidiaries are consolidated unless GAAP requires otherwise. The Company has evaluated subsequent events for potential recognition and/or disclosure through the date these financial statements were issued. Reclassifications Certain items in prior financial statements have been reclassified to conform to the current presentation. Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent liabilities at the date of the financial statements. Actual results could differ from those estimates. Refer to Note 18 – Other Commitments, Contingencies, and Off-Balance Sheet Activities for pandemic related risks and uncertainties. Business Combinations Business combinations are accounted for using the acquisition method of accounting. Under this method, the accounts of an acquired entity are included with the acquirer’s accounts as of the date of acquisition with any excess of purchase price over the fair value of the net assets acquired (including identifiable intangibles) capitalized as goodwill. To consummate an acquisition, the Company will typically issue common stock and/or pay cash, depending on the terms of the acquisition agreement. The value of common shares issued is determined based upon the market price of the stock as of the closing of the acquisition. Cash and Cash equivalents Cash and cash equivalents include cash, balances due from banks, and short-term investments, all of which had an original maturity within 90 days. Due to the nature of cash and cash equivalents and the near term maturity, the Company estimated that the carrying amount of such instruments approximated fair value. The nature of the Bank’s business requires that it maintain amounts due from banks which at times, may exceed federally insured limits. The Bank has not experienced any losses on such amounts and all amounts are maintained with well-capitalized institutions. Trading Security The Company accounts for a tax advantaged economic development bond originated in 2008 at fair value, in accordance with Financial Accounting Standards Board’s (“FASB”) Accounting Standards Codification (“ASC”) 320. The bond has been designated as a trading account security and is recorded at fair value, with changes in unrealized gains and losses recorded through earnings each period as part of non-interest income. Securities Debt securities that management has the intent and ability to hold to maturity are classified as held to maturity and carried at amortized cost. All other debt securities are classified as available for sale and carried at fair value, with unrealized gains and losses reported as a component of other net comprehensive income. Equity securities are carried at fair value, with changes in fair value reported in net income. Management determines the appropriate classification of securities at the time of purchase. Restricted equity securities, such as stock in the Federal Home Loan Bank of Boston (“FHLBB”) are carried at cost. There are no quoted market prices for the Company’s restricted equity securities. The Bank is a member of the FHLBB, which requires that members maintain an investment in FHLBB stock, which may be redeemed based on certain conditions. The Bank reviews for impairment based on the ultimate recoverability of the cost bases in the FHLBB stock. Purchase premiums and discounts are recognized in interest income using the interest method, without anticipating prepayments, except mortgage-backed securities where prepayments are anticipated, over the terms of the securities. Premiums on callable debt securities are amortized to their earliest call date. Gains and losses on the sale of securities are recorded on the trade date and are determined using the specific identification method. The Company measures expected credit losses on held to maturity debt securities on a collective basis. Accrued interest receivable on held to maturity debt securities is excluded from the estimate of credit losses. The estimate of expected credit losses considers historical credit loss information that is adjusted for current conditions and reasonable and supportable forecasts. The Company evaluates available for sale debt securities in an unrealized loss position by first assessing whether it intends to sell or it is more likely than not that it will be required to sell the security before recovery of its amortized cost basis. If either the criteria regarding intent or requirement to sell is met, the security’s amortized cost basis is written down to fair value through income. For available for sale debt securities that do not meet the aforementioned criteria, the Company evaluates whether the decline in fair value has resulted from credit losses or other factors. In making this assessment, the Company considers the extent to which fair value is less than amortized cost, any changes to the rating of security by a rating agency, and adverse conditions specifically related to the security, among other factors. If this assessment indicates that a credit loss exists, the present value of cash flows expected to be collected from the security are compared to the amortized cost basis of the security. If the present value of cash flows expected to be collected is less than the amortized cost basis, a credit loss exists and an allowance for credit losses is recorded for the credit loss, limited by the amount that the fair value is less than the amortized cost basis. Any impairment that has not been recorded through an allowance for credit losses is recognized in other comprehensive income. Loans Held for Sale Loans originated with the intent to be sold in the secondary market are accounted for under the fair value option. Non-refundable fees and direct loan origination costs related to residential mortgage loans held for sale are recognized in non-interest income or non-interest expense as earned or incurred. Fair value is primarily determined based on quoted prices for similar loans in active markets. Gains and losses on sales of residential mortgage loans (sales proceeds minus carrying value) are recorded in non-interest income. Loans that were previously held for investment that the Company has an active plan to sell are transferred to loans held for sale at the lower of cost or market (fair value). The market price is primarily determined based on quoted prices for similar loans in active markets or agreed upon sales prices. Gains are recorded in non-interest income at sale to the extent that the sale price of the loan exceeds carrying value. Any reduction in the loan’s value, prior to being transferred to loans held for sale, is reflected as a charge-off of the recorded investment in the loan resulting in a new cost basis, with a corresponding reduction in the allowance for credit losses. Further decreases in the fair value of the loan are recognized in non-interest expense. Loans Loans are reported at their amortized cost. Amortized cost is the principal balance outstanding, net of the unamortized balance of any deferred fees or costs and the unamortized balance of any premiums or discounts on loans purchased or acquired through mergers. Interest income is accrued on the unpaid principal balance. Interest income includes net accretion or amortization of deferred fees or costs and of premiums or discounts. Direct loan origination costs, net of any origination fees, in addition to premiums and discounts on loans, are deferred and recognized as an adjustment of the related loan yield using the interest method. Interest on loans, excluding automobile loans, is generally not accrued on loans which are ninety days or more past due unless the loan is well-secured and in the process of collection. Past due status is based on contractual terms of the loan. Automobile loans generally continue accruing until one hundred and twenty days delinquent, at which time they are charged off. All interest accrued but not collected for loans that are placed on non-accrual or charged-off is reversed against interest income, except for certain loans designated as well-secured. The interest on non-accrual loans is accounted for on the cash-basis or cost-recovery method, until qualifying for return to accrual. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured. Purchase Credit Deteriorated (PCD) Loans Loans that the Company acquired in acquisitions include some loans that have experienced more than insignificant credit deterioration since origination. PCD loans are recorded at the amount paid. An allowance for credit losses is determined using the same methodology as other loans held for investment. The initial allowance for credit losses determined on a collective basis is allocated to individual loans. The sum of the loan’s purchase price and allowance for credit losses becomes its initial amortized cost basis. The difference between the initial amortized cost basis and the par value of the loan is a noncredit discount or premium, which is amortized into interest income over the life of the loan. Subsequent changes to the allowance for credit losses are recorded through provision expense. Allowance for Credit Losses for Loans The allowance for credit losses for loans (“ACLL”) is comprised of the allowance for loan losses and the allowance for unfunded commitments which is accounted for as a separate liability in other liabilities on the consolidated balance sheet. The ACLL is a valuation account that is deducted from the loans’ amortized cost basis to present the net amount expected to be collected on the loans. Loans are charged off against the allowance when management believes the uncollectibility of a loan balance is confirmed. Accrued interest receivable is excluded from the estimate of credit losses. The level of the ACLL represents management’s estimate of expected credit losses over the expected life of the loans at the balance sheet date. The Company uses a static pool migration analysis method, applying expected historical loss trend and observed economic metrics. The level of the ACLL is based on management’s ongoing review of all relevant information, from internal and external sources, relating to past and current events, utilizing a 7 quarter reasonable and supportable forecast period with a 1 year reversion period. The ACLL reserve is overlaid with qualitative factors based upon: • the existence and growth of concentrations of credit; • the volume and severity of past due financial assets, including nonaccrual assets; • the institutions lending and credit review as well as the experience and ability of relevant management and staff and; • the effect of other external factors such as regulatory, competition, regional market conditions, legal and technological environment and other events such as natural disasters; • the effect of other economic factors such as economic stimulus and customer forbearance programs. The allowance for unfunded commitments is maintained at a level by the Company to be sufficient to absorb expected lifetime losses related to unfunded credit facilities (including unfunded loan commitments and letters of credit). The ACLL is measured on a collective (pool) basis when similar risk characteristics exist. The Company evaluates its risk characteristics of loans based on regulatory call report code with sub-segmentation based on underlying collateral for certain loan types. Risk characteristics relevant to each portfolio segment are as follows: Construction – Loans in this segment primarily include real estate development loans for which payment is derived from sale of the property or long term financing at completion. Credit risk is affected by cost overruns, time to sell at an adequate price, and market conditions. Commercial real estate multifamily, owner occupied and non-owner – Loans in this segment are primarily owner-occupied or income-producing properties throughout New England and Northeastern New York. The underlying cash flows generated by the properties are adversely impacted by a downturn in the economy, which in turn, will have an effect on the credit quality in this segment. Management monitors the cash flows of these loans. Commercial and industrial loans – Loans in this segment are made to businesses and are generally secured by assets of the business such as accounts receivable, inventory, marketable securities, other liquid collateral, equipment and other business assets. Repayment is expected from the cash flows of the business. Loans in this segment include asset based loans which generally have no scheduled repayment which are closely monitored against formula based collateral advance ratios. A weakened economy, and resultant decreased consumer spending, will have an effect on the credit quality of this segment. Residential real estate – All loans in this segment are collateralized by residential real estate and repayment is dependent on the credit quality of the individual borrower. The overall health of the economy, including unemployment rates and housing prices, will have an effect on the credit quality in this segment. Home equity and other consumer loans – Loans in this segment are primarily home equity lines of credit, automobile loans and other consumer loans. The overall health of the economy, including unemployment rates and housing prices, will have an effect on the credit quality in this segment. Loans that do not share risk characteristics are evaluated on an individual basis, which the Company has determined to be non-accrual loans over a certain threshold, loans that were determined to be Troubled Debt Restructurings (“TDRs”) and PCD loans. Loans evaluated individually are not also included in the collective evaluation. Estimates of specific allowance may be determined by the present value of anticipated future cash flows or the loan’s observable fair market value, or the fair value of the collateral less costs to sell, if the loan is collateral dependent. However, for collateral dependent loans, the amount of the amortized cost in a loan that exceeds the fair value of the collateral is charged-off against the allowance for loan losses in lieu of an allocation of a specific allowance amount when such an amount has been identified definitively as uncollectible. Prior to the adoption of ASC 326 on January 1, 2020, the Company calculated allowance for loan losses using incurred losses methodology. Bank-Owned Life Insurance Bank-owned life insurance policies are reflected on the Consolidated Balance Sheets at the amount that can be realized under the insurance contract at the balance sheet date which is the cash surrender value. Changes in the net cash surrender value of the policies, as well as insurance proceeds received, are reflected in non-interest income on the Consolidated Statements of Operations and are not subject to income taxes. Foreclosed and Repossessed Assets Other real estate owned is comprised of real estate acquired through foreclosure proceedings or acceptance of a deed in lieu of foreclosure. Repossessed collateral is primarily comprised of taxi medallions. Both other real estate owned and repossessed collateral are held for sale and are initially recorded at the fair value less estimated costs to sell at the date of foreclosure or repossession, establishing a new cost basis. The shortfall, if any, of the loan balance over the fair value of the property or collateral (excluding taxi medallions), less cost to sell, at the time of transfer from loans to other real estate owned or repossessed collateral is charged to the allowance for loan losses. Subsequent to transfer, the asset is carried at lower of cost or fair value less cost to sell and periodically evaluated for impairment. The shortfall, if any, of the loan balance over the fair value of the collateral comprised of taxi medallions at the time of transfer from loans to repossessed collateral is charged to non-interest income. Subsequent impairments in the fair value of other real estate owned and repossessed collateral are charged to expense in the period incurred. Net operating income or expense related to other real estate owned and repossessed collateral is included in operating expenses in the accompanying Consolidated Statements of Operations. Because of changing market conditions, there are inherent uncertainties in the assumptions with respect to the estimated fair value of other real estate owned and repossessed collateral. Because of these inherent uncertainties, the amount ultimately realized on other real estate owned and repossessed collateral may differ from the amounts reflected in the financial statements. Capitalized Servicing Rights Capitalized servicing rights are included in “other assets” in the Consolidated Balance Sheets. Servicing assets are initially recognized as separate assets at fair value when rights are acquired through purchase or through sale of financial assets with servicing retained. The Company's servicing rights accounted for under the fair value method are carried on the Consolidated Balance Sheets at fair value with changes in fair value recorded in income in the period in which the change occurs. Changes in the fair value of servicing rights are primarily due to changes in valuation assumptions, such as discount rates and prepayment speeds, and the collection and realization of expected cash flows. The Company’s servicing rights accounted for under the amortization method are initially recorded at fair value. Under that method, capitalized servicing rights are charged to expense in proportion to and over the period of estimated net servicing income. Fair value of the servicing rights is based on a valuation model that calculates the present value of estimated future net servicing income. The valuation model incorporates assumptions that market participants would use in estimating future net servicing income, such as the cost to service, the discount rate, prepayment speeds and default rates and losses. Impairment is recognized through a valuation allowance for an individual tranche, to the extent that fair value is less than the capitalized amount for the tranches. If the Company later determines that all or a portion of the impairment no longer exists for a particular tranche, a reduction of the allowance may be recorded as an increase to income. Premises and Equipment Land is carried at cost. Buildings, improvements, and equipment are carried at cost less accumulated depreciation and amortization computed on the straight-line method over the estimated useful lives of the assets. Leasehold improvements are amortized on the straight-line method over the shorter of the lease term, plus optional terms if certain conditions are met, or the estimated useful life of the asset. Goodwill Goodwill represents the excess of the purchase price over the fair value of the net assets acquired in a business combination. Goodwill is assessed annually for impairment, and more frequently if events or changes in circumstances indicate that there may be an impairment. Adverse changes in the economic environment, declining operations, unanticipated competition, loss of key personnel, or other factors could result in a decline in the implied fair value of goodwill. Subsequent reversals of goodwill impairment are prohibited. Other Intangibles Intangible assets are acquired assets that lack physical substance but can be distinguished from goodwill because of contractual or other legal rights or the asset is capable of being sold or exchanged either on its own or in combination with a related contract, asset or liability. The fair values of these assets are generally determined based on appraisals and are subsequently amortized on a straight-line basis or an accelerated basis over their estimated lives. Management assesses the recoverability of these intangible assets at least annually or whenever events or changes in circumstances indicate that their carrying value may not be recoverable. If the carrying amount exceeds fair value, an impairment charge is recorded to income. Transfers of Financial Assets Transfers of an entire financial asset, group of entire financial assets, or a participating interest in an entire financial asset are accounted for as sales when control over the assets has been surrendered. Control over transferred assets is deemed to be surrendered when (1) the assets have been isolated from the Company, (2) the transferee obtains the right to pledge or exchange the transferred assets, and (3) the Company does not maintain effective control over the transferred assets. Income Taxes Deferred income taxes are recognized for the tax consequences of temporary differences by applying enacted statutory tax rates applicable for future years to differences between financial statement and tax bases of existing assets and liabilities. The effect of tax rate changes on deferred taxes is recognized in the income tax provision in the period that includes the enactment date. A tax valuation allowance is established, as needed, to reduce net deferred tax assets to the amount expected to be realized. In the event it becomes more likely than not that some or all of the deferred tax asset allowances will not be needed, the valuation allowance will be adjusted. In the ordinary course of business there is inherent uncertainty in quantifying the Company’s income tax positions. Income tax positions and recorded tax benefits are based upon management’s evaluation of the facts, circumstances, and information available at the reporting date. For those tax positions where it is more likely than not that a tax benefit will be sustained, we have determined the amount of the tax benefit to be recognized by estimating the largest amount of tax benefit that has a greater than 50% likelihood of being realized upon ultimate settlement with a taxing authority that has full knowledge of all relevant information. For those income tax positions where it is more-likely-than-not that a tax benefit will not be sustained, no tax benefit has been recognized in the financial statements. Where applicable, associated interest and penalties have also been recognized. We recognize accrued interest and penalties related to unrecognized tax benefits as a component of income tax expense. Insurance Commissions Commission revenue is recognized as of the effective date of the insurance policy or the date the customer is billed, whichever is later, net of return commissions related to policy cancellations. Policy cancellation is a variable consideration that is not deemed significant and thus, does not impact the amount of revenue recognized. In addition, the Company may receive additional performance commissions based on achieving certain sales and loss experience measures. Such commissions are recognized when determinable, which is generally when such commissions are received or when the Company receives data from the insurance companies that allows the reasonable estimation of these amounts. Stock-Based Compensation The Company measures and recognizes compensation cost relating to share-based payment transactions based on the grant-date fair value of the equity instruments issued. The fair value of restricted stock is recorded as unearned compensation. The deferred expense is amortized to compensation expense based on one of several permitted attribution methods over the longer of the required service period or performance period. For performance-based restricted stock awards, the Company estimates the degree to which performance conditions will be met to determine the number of shares that will vest and the related compensation expense. Compensation expense is adjusted in the period such estimates change. Income tax benefits and/or tax deficiencies related to stock compensation determined as the difference between compensation cost recognized for financial reporting purposes and the deduction for tax, are recognized in the income statement as income tax expense or benefit in the period in which they occur. Wealth Management Wealth management assets held in a fiduciary or agent capacity are not included in the accompanying Consolidated Balance Sheets because they are not assets of the Company. Wealth management fees is primarily comprised of fees earned from consultative investment management, trust administration, tax return preparation, and financial planning. The Company’s performance obligation is generally satisfied over time and the resulting fees are recognized monthly, based on the daily accrual of the market value of the investment accounts and the applicable fee rate. Derivative Instruments and Hedging Activities The Company enters into interest rate swap agreements as part of the Company’s interest rate risk management strategy for certain assets and liabilities and not for speculative purposes. Based on the Company’s intended use for the interest rate swap at inception, the Company designates the derivative as either an economic hedge of an asset or liability or a hedging instrument subject to the hedge accounting provisions of ASC 815, “Derivatives and Hedging.” Interest rate swaps designated as economic hedges are recorded at fair value within other assets or liabilities. Changes in the fair value of these derivatives are recorded directly through earnings. For interest rate swaps that management intends to apply the hedge accounting provisions of ASC 815, the Company formally documents at inception all relationships between hedging instruments and hedged items, as well as its risk management objectives and strategies for undertaking the various hedges. Additionally, the Company uses dollar offset or regression analysis at the hedge’s inception and for each reporting period thereafter, to assess whether the derivative used in its hedging transaction is expected to be and has been highly effective in offsetting changes in the fair value or cash flows of the hedged item. The Company discontinues hedge accounting when it is determined that a derivative is not expected to be or has ceased to be highly effective as a hedge, and then reflects changes in fair value of the derivative in earnings after termination of the hedge relationship. The Company enters into commitments to lend with borrowers, and forward commitments to sell loans or to-be-announced mortgage-backed bonds to investors to hedge against the inherent interest rate and pricing risk associated with selling loans. The commitments to lend generally terminate once the loan is funded, the lock period expires or the borrower decides not to contract for the loan. The forward commitments generally terminate once the loan is sold, the commitment period expires or the borrower decides not to contract for the loan. These commitments are considered derivatives which are accounted for by recognizing their estimated fair value on the Consolidated Balance Sheets as either a freestanding asset or liability. See Note 15 - Derivative Instruments and Hedging Activities to the financial statements for more information on commitments to lend and forward commitments. Off-Balance Sheet Financial Instruments In the ordinary course of business, the Company enters into off-balance sheet financial instruments, consisting primarily of credit related financial instruments. These financial instruments are recorded in the financial statements when they are funded or related fees are incurred or received. Fair Value Hierarchy The Company groups assets and liabilities that are measured at fair value in three levels, based on the markets in which the assets and liabilities are traded and the reliability of the assumptions used to determine fair value. Level 1 - Valuation is based on quoted prices in active markets for identical assets or liabilities. Valuations are obtained from readily available pricing sources for market transactions involving identical assets or liabilities. Level 2 - Valuation is based on observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 3 - Valuation is based on unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. Level 3 assets and liabilities include financial instruments whose value is determined using unobservable techniques, as well as instruments for which the determination of fair value requires significant management judgment or estimation. Employee Benefits The Company maintains an employer sponsored 401(k) plan to which participants may make contributions in the form of salary deferrals and the Company provides matching contributions in accordance with the terms of the plan. Contributions due under the terms of the defined contribution plans are accrued as earned by employees. Due to the Rome Bancorp acquisition in 2011, the Company inherited a noncontributory, qualified, defined benefit pension plan for certain employees who met age and service requirements; as well as other post-retirement benefits, principally health care and group life insurance. The Rome pension plan and postretirement benefits that were acquired in connection with the whole-bank acquisition were frozen prior to the close of the transaction. The pension benefit in the form of a life annuity is based on the employee’s combined years of service, age, and compensation. The Company also has a long-term care post-retirement benefit plan for certain executives where upon disability, associated benefits are funded by insurance policies or paid directly by the Company. In order to measure the expense associated with the Plans, various assumptions are made including the discount rate, expected return on plan assets, anticipated mortality rates, and expected future healthcare costs. The assumptions are based on historical experience as well as current facts and circumstances. The Company uses a December 31 measurement date for its plans. As of the measurement date, plan assets are determined based on fair value, generally representing observable market prices. The projected benefit obligation is primarily determined based on the present value of projected benefit distributions at an assumed discount rate. Net periodic pension benefit costs include interest costs based on an assumed discount rate, the expected return on plan assets based on actuarially derived market-related values, and the amortization of net actuarial losses. Net periodic postretirement benefit costs include service costs, interest costs based on an assumed discount rate, and the amortization of prior service credits and net actuarial gains. Differences between expected and actual results in each year are included in the net actuarial gain or loss amount, which is recognized in other comprehensive income. The net actuarial gain or loss in excess of a 10% corridor is amortized in net periodic benefit cost over the average remaining service period of active participants in the Plans. The prior service credit is amortized over the average remaining service period to full eligibility for participating employees expected to receive benefits. The Company recognizes in its statement of condition an asset for a plan’s overfunded status or a liability for a plan’s underfunded status. The Company also measures the Plans’ assets and obli

DISCONTINUED OPERATIONS

DISCONTINUED OPERATIONS	12 Months Ended

Discontinued Operations and Disposal Groups [Abstract]
DISCONTINUED OPERATIONS	DISCONTINUED OPERATIONS During the first quarter of 2019, the Company reached the decision to pursue the sale of the national mortgage banking operations of First Choice Loan Services, Inc. (“FCLS”) – a subsidiary of the Bank. The decision was based on a number of strategic priorities and other factors, including the competitiveness of the mortgage industry. As a result of these actions, the Company classified the operations of FCLS as discontinued under ASC 205-20. The Consolidated Balance Sheets, Consolidated Statements of Operations, and Consolidated Statements of Cash Flows present discontinued operations retrospectively for current and prior periods. On May 7, 2020, the Company completed a transaction to sell certain assets and liabilities related to the operations of FCLS. During the fourth quarter of 2020, the Company completed the final wind-down of the operations of FCLS. Operating results for the year ended December 31, 2020, included expenses related to the wind-down of operations. At year-end 2021 and 2020, there were no assets or liabilities related to the discontinued operations of FCLS. The following presents operating results of the discontinued operations of FCLS for the years ended December 31, 2021, 2020, and 2019: Years Ended December 31, (in thousands) 2021 2020 2019 Interest income $ — $ 1,525 $ 6,085 Interest expense — 391 3,372 Net interest income — 1,134 2,713 Non-interest (loss)/income — (4,740) 38,517 Total net revenue — (3,606) 41,230 Non-interest expense — 23,249 46,769 (Loss) from discontinued operations before income taxes — (26,855) (5,539) Income tax (benefit) — (7,013) (1,468) Net (loss) from discontinued operations $ — $ (19,842) $ (4,071) FCLS also originated mortgages designated as held-for-investment. This component of FCLS’s operations was not considered discontinued, since the Company expects to continue to originate mortgages designated as held-for-investment in its footprint on a small scale through processes considered as continuing operations. Mid-Atlantic Branch Sale On August 27, 2021 the Company completed the sale of eight Mid-Atlantic branches to Investors Bank of Short Hills, New Jersey. This sale was made pursuant to a purchase and assumption agreement entered into by the banks on December 2, 2020. The sale included all branch premises and equipment, and Investors also assumed related operations and the employment of associated staff. The branch sale is not expected to impact Berkshire’s growing Mid-Atlantic specialized commercial lending operations, including SBA lending at its 44 Business Capital Division and its asset-based lending relationships. The sale involved the assignment of deposits which totaled $631 million and loans which totaled $220 million as of August 27, 2021. These instruments were classified as held for sale in the financial statements and were not included in total deposits and total loans reported by the Company at December 31, 2020. Investors Bank paid a premium of 3.0% of the deposit balance transferred. The Company provided a settlement cash payment of $391 million as part of the sale for the assumption of covered deposit liabilities by Investors.

As a result of these actions, the Company classified the operations of FCLS as discontinued under ASC 205-20.

Credit ratings express opinions about the credit quality of a security and are utilized by the Company to make informed decisions. Investment grade securities are rated BBB-/Baa3 or higher and generally considered by the rating agencies and market participants to be of low credit risk. Conversely, securities rated below investment grade are considered to have distinctively higher credit risk than investment grade securities. For securities without credit ratings, the Company utilizes other financial information indicating the financial health of the underlying municipality, agency, or organization. As of December 31, 2021, none of the Company's investment securities were delinquent or in non-accrual status.

Furthermore, the Company does not intend to sell nor does it anticipate that it will be required to sell any of its securities in an unrealized loss position as of December 31, 2021, prior to this recovery. The Company’s ability and intent to hold these securities until recovery is supported by the Company’s strong capital and liquidity positions. The following summarizes, by investment security type, the basis for the conclusion that the debt securities in an unrealized loss position within the Company’s AFS and HTM portfolios did not maintain other-than-temporary impairment ("OTTI") at year-end 2021: AFS collateralized mortgage obligations At year-end 2021, 45 out of 250 securities in the Company’s portfolio of AFS collateralized mortgage obligations were in unrealized loss positions. Aggregate unrealized losses represented 2.7% of the amortized cost of securities in unrealized loss positions. The Federal National Mortgage Association ("FNMA"), Federal Home Loan Mortgage Corporation ("FHLMC"), and Government National Mortgage Association ("GNMA") guarantee the contractual cash flows of all of the Company's collateralized residential mortgage obligations. The securities are investment grade rated and there were no material underlying credit downgrades during 2021. All securities are performing. AFS commercial and residential mortgage-backed securities At year-end 2021, 28 out of 133 securities in the Company’s portfolio of AFS mortgage-backed securities were in unrealized loss positions. Aggregate unrealized losses represented 2.0% of the amortized cost of securities in unrealized loss positions. The FNMA, FHLMC, and GNMA guarantee the contractual cash flows of the Company’s mortgage-backed securities. The securities are investment grade rated and there were no material underlying credit downgrades during 2021. All securities are performing. AFS corporate bonds At year-end 2021, 5 out of 15 securities in the Company’s portfolio of AFS corporate bonds were in unrealized loss positions. The aggregate unrealized loss represents 1.0% of the amortized cost of bonds in unrealized loss positions. The Company reviews the financial strength of these bonds and has concluded that the amortized cost remains supported by the expected future cash flows of these securities. AFS other bonds and obligations At year-end 2021, 2 out of 6 securities in the Company’s portfolio of other bonds and obligations were in unrealized loss positions. Aggregate unrealized losses represented 1.1% of the amortized cost of securities in unrealized loss positions. The securities are all investment grade rated, and there were no material underlying credit downgrades during 2021. All securities are performing. HTM municipal bonds and obligations At year-end 2021, 26 out of 209 securities in the Company’s portfolio of HTM municipal bonds and obligations were in unrealized loss positions. Aggregate unrealized losses represented 1.8% of the amortized cost of securities in unrealized loss positions. The Company continually monitors the municipal bond sector of the market carefully and periodically evaluates the appropriate level of exposure to the market. At this time, the Company feels the bonds in this portfolio carry minimal risk of default and the Company is appropriately compensated for that risk. There were no material underlying credit downgrades during the quarter. All securities are performing. HTM collateralized mortgage obligations At year-end 2021, 6 out of 14 securities in the Company’s portfolio of HTM collateralized mortgage obligations were in an unrealized loss position. Aggregate unrealized losses represented 4.0% of the amortized cost of the security in an unrealized loss position. The FNMA, FHLMC, and GNMA guarantee the contractual cash flows of all of the Company's collateralized residential mortgage obligations. The securities are investment grade rated, and there were no material underlying credit downgrades during 2021. All securities are performing. HTM commercial and residential mortgage-backed securities At year-end 2021, 15 out of 17 securities in the Company’s portfolio of HTM mortgage-backed securities were in unrealized loss positions. Aggregate unrealized losses represented 2.5% of the amortized cost of securities in unrealized loss positions. The FNMA, FHLMC, and GNMA guarantee the contractual cash flows of the Company’s mortgage-backed securities. The securities are investment grade rated and there were no material underlying credit downgrades during 2021. All securities are performing. HTM tax-advantaged economic development bonds At year-end 2021, 1 out of 3 securities in the Company’s portfolio of tax-advantaged economic development bonds were in an unrealized loss position. Aggregate unrealized losses represented 1.2% of the amortized cost of the security in an unrealized loss position. The Company believes that more likely than not all the principal outstanding will be collected. All securities are performing.

These loans are 100% guaranteed by the SBA and the full principal amount of the loan may qualify for forgiveness. These loans are included in commercial and industrial. In 2021, the Company purchased loans aggregating $211 million and sold loans aggregating $560 million. In 2020, the Company purchased loans aggregating $98 million and sold loans aggregating $415 million. Net gains on sales of loans were $20.7 million, $10.6 million, and $12.0 million for the years 2021, 2020, and 2019, respectively. These amounts are included in Loan Related Income on the Consolidated Statements of Operations. Most of the Company’s lending activity occurs within its primary markets in Massachusetts, Southern Vermont, and Northeastern New York. Most of the loan portfolio is secured by real estate, including residential mortgages, commercial mortgages, and home equity loans. Year-end loans to operators of non-residential buildings totaled $1.6 billion, or 24.0%, and $1.5 billion, or 19.0% of total loans in 2021 and 2020, respectively. There were no other concentrations of loans related to any single industry in excess of 10% of total loans at year-end 2021 or 2020. As of December 31, 2021, the Company had no foreclosed residential real estate property. As of December 31, 2020, the Company maintained foreclosed residential real estate property with fair value of $149 thousand. Additionally, residential mortgage loans collateralized by real estate property that are in the process of foreclosure as of December 31, 2021 and December 31, 2020 totaled $1.4 million and $3.3 million, respectively, including sold loans serviced by the Company. At year-end 2021, the Company had pledged loans totaling $0.7 billion to the Federal Reserve Bank of Boston as collateral for certain borrowing arrangements. Also, residential first mortgage loans are subject to a blanket lien for FHLBB advances. See Note 12 - Borrowed Funds. At year-end 2021 and 2020, the Company’s commitments outstanding to related parties totaled $1.7 million and $2.0 million, respectively, and the loans outstanding against these commitments totaled $1.0 million and $1.1 million, respectively. Related parties include directors and executive officers of the Company and its subsidiaries, as well as their respective affiliates in which they have a controlling interest and immediate family members. For the years 2021 and 2020, all related party loans were performing. Risk characteristics relevant to each portfolio segment are as follows: Construction - Loans in this segment primarily include real estate development loans for which payment is derived from sale of the property or long term financing at completion. Credit risk is affected by cost overruns, time to sell at an adequate price, and market conditions. Commercial real estate multifamily, owner occupied and non-owner - Loans in these segments are primarily owner-occupied or income-producing properties throughout New England and Northeastern New York. The underlying cash flows generated by the properties are adversely impacted by a downturn in the economy, which in turn, will have an effect on the credit quality in this segment. Management monitors the cash flows of these loans. Commercial and industrial loans - Loans in this segment are made to businesses and are generally secured by assets of the business such as accounts receivable, inventory, marketable securities, other liquid collateral, equipment and other business assets. Repayment is expected from the cash flows of the business. Loans in this segment include asset based loans which generally have no scheduled repayment and which are closely monitored against formula based collateral advance ratios. A weakened economy, and resultant decreased consumer spending, will have an effect on the credit quality in this segment. Residential real estate - All loans in this segment are collateralized by residential real estate and repayment is dependent on the credit quality of the individual borrower. The overall health of the economy, including unemployment rates and housing prices, will have an effect on the credit quality in this segment. Home equity and other consumer loans - Loans in this segment are primarily home equity lines of credit, automobile loans and other consumer loans. The overall health of the economy, including unemployment rates and housing prices, will have an effect on the credit quality in this segment. Allowance for Credit Losses for Loans The Allowance for Credit Losses for Loans (“ACLL”) is comprised of the allowance for loan losses, and the allowance for unfunded commitments is accounted for as a separate liability in other liabilities on the balance sheet. The level of the ACLL represents management’s estimate of expected credit losses over the expected life of the loans at the balance sheet date. The Company uses a static pool migration analysis method, applying expected historical loss trend and observed economic metrics. The level of the ACLL is based on management’s ongoing review of all relevant information, from internal and external sources, relating to past and current events, utilizing a 7 quarter reasonable and supportable forecast period with a 1 year reversion period. The ACLL reserve is overlaid with qualitative factors based upon: • the existence and growth of concentrations of credit; • the volume and severity of past due financial assets, including nonaccrual assets; • the institutions lending and credit review as well as the experience and ability of relevant management and staff and; • the effect of other external factors such as regulatory, competition, regional market conditions, legal and technological environment and other events such as natural disasters; • the effect of other economic factors such as economic stimulus and customer forbearance programs. The allowance for unfunded commitments is maintained at a level by the Company to be sufficient to absorb expected lifetime losses related to unfunded credit facilities (including unfunded loan commitments and letters of credit).

Loans that are given a Pass rating are not considered a problem credit. Loans that are classified as Special Mention loans are considered to have potential weaknesses and are evaluated closely by management. Substandard, including non-accruing loans, are loans for which a definitive weakness has been identified and which may make full collection of contractual cash flows questionable. Doubtful loans are those with identified weaknesses that make full collection of contractual cash flows, on the basis of currently existing facts, conditions, and values, highly questionable and improbable. For commercial credits, the Company assigns an internal risk rating at origination and reviews the rating annually, semiannually, or quarterly depending on the risk rating. The rating is also reassessed at any point in time when management becomes aware of information that may affect the borrower’s ability to fulfill their obligations. The Company risk rates its residential mortgages, including 1-4 family and residential construction loans, based on a three rating system: Pass, Special Mention, and Substandard. Loans that are current within 59 days are rated Pass. Residential mortgages that are 60-89 days delinquent are rated Special Mention. Loans delinquent for 90 days or greater are rated Substandard and generally placed on non-accrual status.

A financial asset is considered collateral-dependent when the debtor is experiencing financial difficulty and repayment is expected to be provided substantially through the sale or operation of the collateral. Expected credit losses for collateral-dependent loans are based on the fair value of the collateral at the reporting date, adjusted for selling costs as appropriate. Significant quarter over quarter changes are reflective of changes in nonaccrual status and not necessarily associated with credit quality indicators like appraisal value.

These concessions typically result from the Company’s loss mitigation activities and could include reductions in the interest rate, payment extensions, forgiveness of principal, forbearance, or other actions.

Goodwill and Intangible Assets Disclosure [Abstract]
GOODWILL AND OTHER INTANGIBLES	GOODWILL AND OTHER INTANGIBLES Goodwill and other intangible assets are presented in the tables below. The Company had no acquisition during 2021 or 2020. In accordance with applicable accounting guidance, the Company allocated the amount paid to the fair value of the net assets acquired, with any excess amounts recorded as goodwill. The goodwill balance is allocated to the consolidated Company. The activity impacting goodwill in 2021 and 2020 is as follows: (In thousands) 2021 2020 Balance, beginning of the period $ — $ 553,762 Goodwill acquired and adjusted: Impairment — (553,762) Balance, end of the period $ — $ — ______________________________________________________________________________________________________ Goodwill represents the excess of the purchase price over the fair value of the net assets acquired in a business combination. Goodwill is assessed annually for impairment and more frequently if events or changes in circumstances indicate that there may be an impairment. The Company tests goodwill impairment annually as of June 30 using second quarter data. The Company compares the fair value of the reporting unit with its carrying amount, including goodwill. If the carrying amount of a reporting unit exceeds its fair value, an impairment loss is recognized in an amount equal to that excess. The fair value of the reporting unit was determined using the guideline public company method. As a result of the assessment, the Company recognized a full goodwill impairment during the year ended December 31, 2020. The primary causes of the goodwill impairment were economic and industry conditions resulting from the COVID-19 pandemic that caused volatility and reductions in the market capitalization of the Company and its peer banks, increased loan provision estimates, increased discount rates and other changes in variables driven by the uncertain macro-environment that resulted in the estimated fair value of the reporting unit being less than the reporting unit’s carrying value. The components of other intangible assets are as follows: (In thousands) Gross Intangible Accumulated Net Intangible December 31, 2021 Non-maturity deposits (core deposit intangible) $ 77,213 $ (49,963) $ 27,250 Insurance contracts 7,558 (7,558) — All other intangible assets 7,866 (5,497) 2,369 Total $ 92,637 $ (63,018) $ 29,619 December 31, 2020 Non-maturity deposits (core deposit intangible) (1) $ 77,213 $ (45,257) $ 31,956 Insurance contracts 7,558 (7,558) — All other intangible assets 7,866 (5,003) 2,863 Total $ 92,637 $ (57,818) $ 34,819 (1) As of December 31, 2020, the Company reclassified $4.6 million of net core deposit intangible to held-for-sale related to the assets and liabilities associated with the Mid-Atlantic branch sale. Other intangible assets are amortized on a straight-line or accelerated basis over their estimated lives, which range from four fifteen years . Amortization expense related to intangibles totaled $5.2 million in 2021, $6.2 million in 2020, and $5.8 million in 2019. The estimated aggregate future amortization expense for intangible assets remaining at year-end 2021 is as follows: 2022- $5.1 million; 2023- $4.8 million; 2024- $4.6 million; 2025- $4.5 million; 2026- $4.5 million; and thereafter- $6.0 million.

Retirement Benefits [Abstract]
EMPLOYEE BENEFIT PLANS	EMPLOYEE BENEFIT PLANS Pension Plan The Company maintains a legacy, employer-sponsored defined benefit pension plan (the “Plan”) for which participation and benefit accruals were frozen on January 1, 2003. The Plan was assumed in connection with the Rome Bancorp acquisition in 2011. Accordingly, no employees are permitted to commence participation in the Plan and future salary increases and years of credited service are not considered when computing an employee’s benefits under the Plan. As of December 31, 2021, all minimum Employee Retirement Income Security Act (“ERISA”) funding requirements have been met. Information regarding the pension plan is as follows: December 31, (In thousands) 2021 2020 Change in projected benefit obligation: Projected benefit obligation at beginning of year $ 6,121 $ 5,848 Service Cost 59 66 Interest cost 140 178 Actuarial loss (211) 519 Benefits paid (321) (337) Settlements (460) (153) Projected benefit obligation at end of year 5,328 6,121 Accumulated benefit obligation 5,328 6,121 Change in fair value of plan assets: Fair value of plan assets at plan beginning of year 6,049 5,799 Actual return on plan assets 694 740 Contributions by employer — — Benefits paid (321) (337) Settlements (460) (153) Fair value of plan assets at end of year 5,962 6,049 (Overfunded)/underfunded status $ (634) $ 72 Amounts Recognized on Consolidated Balance Sheets Other assets $ 634 $ — Other liabilities — 72 Net periodic pension cost is comprised of the following: December 31, (In thousands) 2021 2020 Service Cost $ 59 $ 66 Interest Cost 140 178 Expected return on plan assets (410) (393) Amortization of unrecognized actuarial loss 103 94 Net periodic pension (credit) $ (108) $ (55) Changes in plan assets and benefit obligations recognized in accumulated other comprehensive income are as follows: December 31, (In thousands) 2021 2020 Amortization of actuarial (loss) $ (103) $ (94) Actuarial (gain) loss (495) 171 Settlement charge (58) — Total recognized in accumulated other comprehensive income (656) 77 Total recognized in net periodic pension cost recognized and other comprehensive income $ (764) $ 22 The amounts in accumulated other comprehensive income that have not yet been recognized as components of net periodic benefit cost are a net loss of $0.7 million and $1.3 million in 2021 and 2020, respectively. The Company did not make any cash contributions to the pension trust during 2021 and 2020. The Company does not expect to make any cash contributions in 2022. The amount expected to be amortized from other comprehensive income into net periodic pension cost over the next fiscal year is $11 thousand. The principal actuarial assumptions used are as follows: December 31, 2021 2020 Projected benefit obligation Discount rate 2.73 % 2.35 % Net periodic pension cost Discount rate 2.35 % 3.15 % Long term rate of return on plan assets 7.00 % 7.00 % The discount rate that is used in the measurement of the pension obligation is determined by comparing the expected future retirement payment cash flows of the pension plan to the Above Median FTSE Pension Discount Curve as of the measurement date. The expected long-term rate of return on Plan assets reflects long-term earnings expectations on existing Plan assets and those contributions expected to be received during the current plan year. In estimating that rate, appropriate consideration was given to historical returns earned by Plan assets in the fund and the rates of return expected to be available for reinvestment. The rates of return were adjusted to reflect current capital market assumptions and changes in investment allocations. The Company’s overall investment strategy with respect to the Plan’s assets is primarily for preservation of capital and to provide regular dividend and interest payments. The Plan’s targeted asset allocation is 65% equity securities via investment in the Long-Term Growth - Equity Portfolio ("LTGE"), 34% intermediate-term investment grade bonds via investment in the Long-Term Growth - Fixed-Income Portfolio ("LTGFI"), and 1% in cash equivalents portfolio (for liquidity). Equity securities include investments in a diverse mix of equity funds to gain exposure in the US and international markets. The fixed income portion of the Plan assets is a diversified portfolio that primarily invests in intermediate-term bond funds. The overall rate of return is based on the historical performance of the assets applied against the Plan’s target allocation, and is adjusted for the long-term inflation rate. The fair values for investment securities are determined by quoted prices in active markets, if available (Level 1). For securities where quoted prices are not available, fair values are calculated based on market prices of similar securities (Level 2). For securities where quoted prices or market prices of similar securities are not available, fair values are calculated using discounted cash flows or other market indicators (Level 3). The fair value of the Plan’s assets by category within the fair value hierarchy are as follows at December 31, 2021 and December 31, 2020. The Plan did not hold any assets classified as Level 3, nor were there any transfers.

(“SIFI”), the Company participates in the Pentegra Defined Benefit Plan for Financial Institutions (the “Plan”), a tax-qualified defined benefit pension plan. The Plan operates as a multiple-employer plan under ERISA and the Internal Revenue Code, and as a multi-employer plan for accounting purposes. The Plan was frozen effective September 6, 2013. The Company made contributions of $149 thousand in 2021. As of July 1, 2021, the Plan held assets with a market value of $4.8 million and liabilities with a market value of $7.4 million. The funded status (market value of plan assets divided by funding target) of the Plan, was greater than 80% as of July 1, 2021, as required by federal and state regulations. Market value of the Plan's assets reflects contributions received through June 30, 2021. There are no collective bargaining agreements in place that require contributions to the Plan by the Company. The Plan is a single plan under the Internal Revenue Code and, as a result, all of the assets stand behind all of the liabilities. Accordingly, contributions made by a participating employer may be used to provide benefits to participants of other participating employers. Postretirement Benefits The Company maintains an unfunded postretirement medical plan assumed in connection with the Rome Bancorp acquisition in 2011. The postretirement plan has been modified so that participation is closed to those employees who did not meet the retirement eligibility requirements by March 31, 2011. The Company contributes partially to medical benefits and life insurance coverage for retirees. Such retirees and their surviving spouses are responsible for the remainder of the medical benefits, including increases in premiums levels, between the total premium and the Company’s contribution. The Company also has an executive long-term care (“LTC”) postretirement benefit plan which started August 1, 2014. The LTC plan reimburses executives for certain costs in the event of a future chronic illness. Funding of the plan comes from Company paid insurance policies or direct payments. At plan’s inception, a $558 thousand benefit obligation was recorded against equity representing the prior service cost of plan participants. Information regarding the postretirement plans is as follows: December 31, (In thousands) 2021 2020 Change in accumulated postretirement benefit obligation: Accumulated post-retirement benefit obligation at beginning of year $ 4,641 $ 4,039 Service Cost 13 39 Interest cost 113 129 Participant contributions — — Actuarial loss (198) 507 Benefits paid (48) (73) Accumulated post-retirement benefit obligation at end of year $ 4,521 $ 4,641 Change in plan assets: Fair value of plan assets at beginning of year $ — $ — Contributions by employer 48 73 Contributions by participant — — Benefits paid (48) (73) Fair value of plan assets at end of year $ — $ — Amounts Recognized on Consolidated Balance Sheets Other Liabilities $ 4,521 $ 4,641 Net periodic post-retirement cost is comprised of the following: December 31, (In thousands) 2021 2020 Service cost $ 13 $ 39 Interest costs 113 129 Amortization of net prior service credit 83 84 Amortization of net actuarial loss 55 12 Net periodic post-retirement costs $ 264 $ 264 Changes in benefit obligations recognized in accumulated other comprehensive income are as follows: December 31, (In thousands) 2021 2020 Amortization of prior service credit $ (83) $ (84) Net actuarial (gain)/loss (253) 496 Total recognized in accumulated other comprehensive income (336) 412 Accrued post-retirement liability recognized $ 4,521 $ 4,641 The amounts in accumulated other comprehensive income that have not yet been recognized as components of net periodic benefit cost are as follows: December 31, (In thousands) 2021 2020 Net prior service cost $ 1,242 $ 1,325 Net actuarial loss 615 869 Total recognized in accumulated other comprehensive income $ 1,857 $ 2,194 The amount expected to be amortized from other comprehensive income into net periodic postretirement cost over the next fiscal year is $83 thousand. The discount rates used in the measurement of the postretirement plan obligations are determined by comparing the expected future retirement payment cash flows of the plans to the Above Median FTSE Pension Discount Curve as of the measurement date. The assumed discount rates on a weighted-average basis were 2.30% and 2.16% as of December 31, 2021 and December 31, 2020, respectively. The Company has fixed contributions, therefore, the annual rate of increase in healthcare costs is not used in measuring the accumulated post-retirement benefit medical obligation. For participants in the LTC plan covered by insurance policies, no increase in annual premiums is assumed based on the history of the corresponding insurance provider. Estimated benefit payments under the post-retirement benefit plan over the next ten years at December 31, 2021 are as follows: Year Payments (In thousands) 2022 126 2023 122 2024 121 2025 117 2026 - 2031 624 401(k) Plan The Company provides a 401(k) Plan in which most eligible employees participate. Expense related to the plan was $3.2 million in 2021, $3.5 million in 2020, and $4.1 million in 2019. Employee Stock Ownership Plan (“ESOP”) As part of the SI Financial acquisition in 2019, the Company acquired an ESOP plan that was frozen and terminated prior to the completion of the transaction. On acquisition date, all amounts in the plan were vested and the loan under the plans was repaid from the sale proceeds of unallocated shares. Other Plans The Company maintains supplemental executive retirement plans (“SERPs”) for select current and former executives. Benefits generally commence no earlier than age sixty-two The Company has endorsement split-dollar arrangements pertaining to certain current and former executives and directors. Under these arrangements, the Company purchased policies insuring the lives of the executives and directors, and separately entered into agreements to split the policy benefits with the individuals. There are no post-retirement benefits associated with these policies. The Company also assumed split-dollar life insurance agreements from multiple prior acquisitions. The accrued liability for these split-dollar arrangements was $7.8 million as of year-end 2021 and $7.9 million as of year-end 2020.

Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES Provision for Income Taxes The components of the Company’s provision for income taxes for the years ended December 31, 2021, 2020, and 2019 were, as follows: (In thousands) 2021 2020 2019 Current: Federal tax expense/(benefit) $ 17,340 $ (19,889) $ 16,576 State tax expense/(benefit) 7,580 (3,976) 5,323 Total current tax expense/(benefit) (1) 24,920 (23,865) 21,899 Deferred: Federal tax expense 5,125 2,048 908 State tax expense/(benefit) 112 1,964 (344) Total deferred tax expense 5,237 4,012 564 Change in valuation allowance 200 — — Income tax expense/(benefit) from continuing operations $ 30,357 $ (19,853) $ 22,463 Income tax (benefit) from discontinued operations — (7,013) (1,468) Total $ 30,357 $ (26,866) $ 20,995 (1) On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security Act (the "CARES Act") was signed into law. The CARES Act includes several provisions that temporarily modify the corporate net operating loss (“NOL”) carryback rules for federal income tax purposes. Specifically, the CARES Act allows a five-year carryback of any NOL generated in a taxable year beginning after December 31, 2017, and before January 1, 2021. The Company recorded a $6 million federal income tax benefit in 2020, and an additional $500 thousand benefit in 2021 resulting from the carryback of its 2020 NOL to recover federal income taxes paid in 2015 through 2018 at a 35% federal income tax rate. Effective Tax Rate The following is a reconciliation of the statutory federal income tax rate to the Company’s effective tax rate for the years ended December 31, 2021, 2020, and 2019: 2021 2020 2019 (In thousands, except rates) Amount Rate Amount Rate Amount Rate Statutory tax rate $ 31,294 21.0 % $ (111,936) 21.0 % $ 26,037 21.0 % Increase (decrease) resulting from: State taxes, net of federal tax benefit 6,077 4.1 (1,589) 0.3 3,641 2.9 Tax exempt income - investments, net (3,475) (2.3) (3,184) 0.6 (3,527) (2.8) Bank-owned life insurance (1,348) (0.9) (1,283) 0.3 (1,305) (1.1) Goodwill impairment — — 103,912 (19.5) — — Non-deductible merger costs — — — — 122 0.1 Tax credits, net of basis reduction (2,881) (1.9) (1,812) 0.3 (3,531) (2.8) Change in valuation allowance 200 0.1 — — — — Tax rate benefit on net operating loss carryback (493) (0.3) (6,040) 1.1 — — Other, net 983 0.6 2,079 (0.4) 1,026 0.8 Effective tax rate $ 30,357 20.4 % $ (19,853) 3.7 % $ 22,463 18.1 % Deferred Tax Assets and Liabilities As of December 31, 2021 and 2020, significant components of the Company’s deferred tax assets and liabilities were, as follows: (In thousands) 2021 2020 Deferred tax assets: Allowance for credit losses $ 30,441 $ 35,650 Unrealized capital loss on tax credit investments 1,451 2,360 Net unrealized loss on securities available for sale and pension in OCI 1,085 — Employee benefit plans 8,435 7,607 Purchase accounting adjustments 4,829 8,843 Net operating loss carryforwards 1,139 1,753 Deferred loan fees 2,449 — Lease liability 14,940 20,119 Premises and equipment 1,850 1,097 Nonaccrual interest 1,722 1,780 Other 1,845 1,733 Deferred tax assets, net before valuation allowances 70,186 80,942 Valuation allowance (400) (200) Deferred tax assets, net of valuation allowances $ 69,786 $ 80,742 Deferred tax liabilities: Net unrealized gain on securities available for sale and pension in OCI $ — $ (10,602) Loan servicing rights (1,488) (1,674) Deferred loan fees — (368) Intangible amortization (545) (2,277) Unamortized tax credit reserve (1,075) (1,086) Right-of-use asset (14,058) (18,365) Deferred tax liabilities $ (17,166) $ (34,372) Deferred tax assets, net $ 52,620 $ 46,370 The Company’s net deferred tax asset increased by $6.3 million during 2021. Deferred tax assets, net of valuation allowances, are expected to be realized through the reversal of existing taxable temporary differences and future taxable income. Valuation Allowances The components of the Company’s valuation allowance on its deferred tax asset, net as of December 31, 2021 and 2020 were, as follows: (in thousands) 2021 2020 State valuation allowances $ (400) $ (200) The state tax basis difference, net of Federal benefit, was originally recorded in 2012, due to management’s assessment that it is more likely than not that certain deferred tax assets recorded for the difference between the book basis and the state tax basis in certain tax credit limited partnership investments (LPs) will not be realized. Management anticipates that the remaining excess state tax basis will be realized as a capital loss upon disposition, and that it is unlikely that the Company will have capital gains against which to offset such capital losses. The Company has established an additional $200 thousand valuation allowance in 2021 as management anticipates that a portion of the state net operating loss carryforwards may not be utilized. The valuation allowance as of December 31, 2021 is subject to change in the future as the Company continues to periodically assess the likelihood of realizing its deferred tax assets. Tax Attributes At December 31, 2021, the Company has $2.5 million of federal net operating loss carryforwards, the utilization of which are limited under Internal Revenue Code Section 382. These net operating losses begin to expire in 2029. The related deferred tax asset is $527 thousand. State net operating loss carryforwards, net of valuation allowance described above, are expected to be utilized in the future and begin to expire in 2023. The related gross deferred tax asset is $612 thousand. Unrecognized Tax Benefits On a periodic basis, the Company evaluates its income tax positions based on tax laws and regulations and financial reporting considerations, and records adjustments as appropriate. This evaluation takes into consideration the status of taxing authorities’ current examinations of the Company’s tax returns, recent positions taken by the taxing authorities on similar transactions, if any, and the overall tax environment in relation to uncertain tax positions. The following table presents changes in unrecognized tax benefits for the years ended December 31, 2021, 2020, and 2019: (In thousands) 2021 2020 2019 Unrecognized tax benefits at January 1 $ 516 $ 238 $ 467 Increase in gross amounts of tax positions related to prior years 509 309 26 Decrease in gross amounts of tax positions related to prior years — — — Decrease due to settlement with taxing authority — — (185) Decrease due to lapse in statute of limitations — (31) (70) Unrecognized tax benefits at December 31 $ 1,025 $ 516 $ 238 It is reasonably possible that over the next twelve months the amount of unrecognized tax benefits may change from the reevaluation of uncertain tax positions arising in examinations, in appeals, or in the courts, or from the closure of tax statutes. The Company does not expect any significant changes in unrecognized tax benefits during the next twelve months. All of the Company’s unrecognized tax benefits, if recognized, would be recorded as a component of income tax expense, therefore, affecting the effective tax rate. The Company recognizes interest and penalties, if any, related to the liability for uncertain tax positions as a component of income tax expense. The accrual for interest and penalties was not material for all years presented. The Company and its subsidiaries file income tax returns in the U.S. federal jurisdiction as well as in various states. In the normal course of business, the Company is subject to U.S. federal, state, and local income tax examinations by tax authorities. The Company is no longer subject to examination for tax years prior to 2018 including any related income tax filings from its recent acquisitions. The Company has been selected for a limited scope audit in the state of New York for tax year 2020.

DERIVATIVE INSTRUMENTS AND HEDG

DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES	12 Months Ended

Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES	DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES At year-end 2021, the Company held derivatives with a total notional amount of $3.7 billion. The Company had economic hedges and non-hedging derivatives totaling $3.7 billion and $8.2 million, respectively, which are not designated as hedges for accounting purposes and are therefore recorded at fair value with changes in fair value recorded directly through earnings. Economic hedges included interest rate swaps totaling $3.4 billion, risk participation agreements with dealer banks of $321.0 million, and $6.4 million in forward commitment contracts. As part of the Company’s risk management strategy, the Company enters into interest rate swap agreements to mitigate the interest rate risk inherent in certain of the Company’s assets and liabilities. Interest rate swap agreements involve the risk of dealing with both Bank customers and institutional derivative counterparties and their ability to meet contractual terms. The agreements are entered into with counterparties that meet established credit standards and contain master netting and collateral provisions protecting the at-risk party. The derivatives program is overseen by the Risk Management Committee of the Company’s Board of Directors. Based on adherence to the Company’s credit standards and the presence of the netting and collateral provisions, the Company believes that the credit risk inherent in these contracts was not significant at December 31, 2021. The Company pledged collateral to derivative counterparties in the form of cash totaling $43.7 million and securities with an amortized cost of $34.8 million and a fair value of $34.9 million at year-end 2021. At December 31, 2020, the Company pledged cash collateral of $75.1 million and securities with an amortized cost of $37.5 million and a fair value of $37.8 million. The Company does not typically require its commercial customers to post cash or securities as collateral on its program of back-to-back economic hedges. However certain language is written into the International Swaps Dealers Association, Inc. (“ISDA”) and loan documents where, in default situations, the Bank is allowed to access collateral supporting the loan relationship to recover any losses suffered on the derivative asset or liability. The Company may need to post additional collateral in the future in proportion to potential increases in unrealized loss positions. Information about interest rate swap agreements and non-hedging derivative assets and liabilities at December 31, 2021 follows: Notional Weighted Weighted Average Rate Estimated December 31, 2021 Received Contract pay rate (In thousands) (In years) (In thousands) Economic hedges: Interest rate swap on tax advantaged economic development bond $ 7,879 7.9 0.47 % 5.09 % $ (1,158) Interest rate swaps on loans with commercial loan customers 1,684,238 5.8 3.99 % 1.91 % 74,348 Reverse interest rate swaps on loans with commercial loan customers (1) 1,684,238 5.8 1.91 % 3.99 % (30,454) Risk participation agreements with dealer banks 320,981 5.8 432 Forward sale commitments 6,377 0.2 134 Total economic hedges 3,703,713 43,302 Non-hedging derivatives: Commitments to lend 8,192 0.2 124 Total non-hedging derivatives 8,192 124 Total $ 3,711,905 $ 43,426 (1) Fair value estimates include the impact of $45.7 million settled to market contract agreements.

Economic hedges As of December 31, 2021 the Company has an interest rate swap with a $7.9 million notional amount to swap out the fixed rate of interest on an economic development bond bearing a fixed rate of 5.09%, currently within the Company’s trading portfolio under the fair value option, in exchange for a LIBOR-based floating rate. The intent of the economic hedge is to improve the Company’s asset sensitivity to changing interest rates in anticipation of favorable average floating rates of interest over the 21-year life of the bond. The fair value changes of the economic development bond are mostly offset by fair value changes of the related interest rate swap. The Company also offers certain derivative products directly to qualified commercial borrowers. The Company economically hedges derivative transactions executed with commercial borrowers by entering into mirror-image, offsetting derivatives with third-party financial institutions. The transaction allows the Company’s customer to convert a variable-rate loan to a fixed rate loan. Because the Company acts as an intermediary for its customer, changes in the fair value of the underlying derivative contracts mostly offset each other in earnings. Credit valuation loss adjustments arising from the difference in credit worthiness of the commercial loan and financial institution counterparties totaled $0.9 million at year-end 2021. The interest income and expense on these mirror image swaps exactly offset each other. The Company has risk participation agreements with dealer banks. Risk participation agreements occur when the Company participates on a loan and a swap where another bank is the lead. The Company earns a fee to take on the risk associated with having to make the lead bank whole on Berkshire’s portion of the pro-rated swap should the borrower default. The Company utilizes forward sale commitments to hedge interest rate risk and the associated effects on the fair value of interest rate lock commitments and loans held for sale. The forward sale commitments are accounted for as derivatives with changes in fair value recorded in current period earnings. Forward sale commitments are included in discontinued operations. The company uses the following types of forward sale commitments contracts: • Best efforts loan sales, • Mandatory delivery loan sales, and • To be announced (TBA) mortgage-backed securities sales. A best efforts contract refers to a loan sales agreement where the Company commits to deliver an individual mortgage loan of a specified principal amount and quality to an investor if the loan to the underlying borrower closes. The Company may enter into a best efforts contract once the price is known, which is shortly after the potential borrower’s interest rate is locked. A mandatory delivery contract is a loan sales agreement where the Company commits to deliver a certain principal amount of mortgage loans to an investor at a specified price on or before a specified date. Generally, the Company may enter into mandatory delivery contracts shortly after the loan closes with a customer. The Company may sell to-be-announced mortgage-backed securities to hedge the changes in fair value of interest rate lock commitments and held for sale loans, which do not have corresponding best efforts or mandatory delivery contracts. These security sales transactions are closed once mandatory contracts are written. On the closing date the price of the security is locked-in, and the sale is paired-off with a purchase of the same security. Settlement of the security purchase/sale transaction is done with cash on a net-basis. Non-hedging derivatives The Company enters into commitments to lend for residential mortgage loans, which commit the Company to lend funds to a potential borrower at a specific interest rate and within a specified period of time. Commitments that relate to the origination of mortgage loans that will be held for sale are considered derivative financial instruments under applicable accounting guidance. Outstanding commitments expose the Company to the risk that the price of the mortgage loans underlying the commitments may decline due to increases in mortgage interest rates from inception of the rate lock to the funding of the loan. The commitments are free-standing derivatives which are carried at fair value with changes recorded in non-interest income in the Company’s Consolidated Statements of Operations. Changes in the fair value of commitments subsequent to inception are based on changes in the fair value of the underlying loan resulting from the fulfillment of the commitment and changes in the probability that the loan will fund within the terms of the commitment, which is affected primarily by changes in interest rates and the passage of time. Commitments to lend are included in discontinued operations. Amounts included in the Consolidated Statements of Operations related to economic hedges and non-hedging derivatives were as follows: Years Ended December 31, (In thousands) 2021 2020 2019 Economic hedges Interest rate swap on industrial revenue bond: Unrealized gain/(loss) recognized in other non-interest income $ 619 $ (289) $ (248) Interest rate swaps on loans with commercial loan customers: Unrealized (loss)/gain recognized in other non-interest income (86,099) 85,206 65,098 Favorable/(unfavorable) change in credit valuation adjustment recognized in other non-interest income 1,431 (1,516) (1,214) Reverse interest rate swaps on loans with commercial loan customers: Unrealized gain/(loss) recognized in other non-interest income 86,099 (85,206) (65,098) Risk Participation Agreements: Unrealized (loss)/gain recognized in other non-interest income (233) 345 83 Forward Commitments: Unrealized (loss)/gain recognized in discontinued operations (186) 547 507 Realized (loss) in discontinued operations — (8,205) (9,195) Non-hedging derivatives Commitments to lend: Unrealized (loss)/gain recognized in discontinued operations $ (611) $ (1,893) $ (1,299) Realized gain in discontinued operations — 15,672 57,699 Realized gain in other non-interest income 2,854 — — Assets and Liabilities Subject to Enforceable Master Netting Arrangements Interest Rate Swap Agreements (“Swap Agreements”) The Company enters into swap agreements to facilitate the risk management strategies for commercial banking customers. The Company mitigates this risk by entering into equal and offsetting swap agreements with highly rated third party financial institutions. The swap agreements are free-standing derivatives and are recorded at fair value in the Company’s Consolidated Balance Sheets. The Company is party to master netting arrangements with its financial institution counterparties; however, the Company does not offset assets and liabilities under these arrangements for financial statement presentation purposes. The master netting arrangements provide for a single net settlement of all swap agreements, as well as collateral, in the event of default on, or termination of, any one contract. Collateral generally in the form of marketable securities is received or posted by the counterparty with net liability positions, respectively, in accordance with contract thresholds. The Company had net asset positions with its financial institution counterparties totaling $2.2 million and $1.0 million as of December 31, 2021 and December 31, 2020, respectively. The Company had net asset positions with its commercial banking counterparties totaling $76.8 million and $159.0 million as of December 31, 2021 and December 31, 2020, respectively. The Company had net liability positions with its financial institution counterparties totaling $33.3 million and $66.8 million as of December 31, 2021 and December 31, 2020, respectively.

Commitments and Contingencies Disclosure [Abstract]
OTHER COMMITMENTS, CONTINGENCIES, AND OFF-BALANCE SHEET ACTIVITIES	OTHER COMMITMENTS, CONTINGENCIES, AND OFF-BALANCE SHEET ACTIVITIES In December 2019, a novel strain of coronavirus (“COVID-19”) was reported to have surfaced in China and has since spread to a number of other countries, including the United States. In March 2020, the World Health Organization declared COVID-19 a global pandemic and the United States declared a National Public Health Emergency. The impact of the COVID-19 pandemic is fluid and continues to evolve, which is adversely affecting some of the Company’s clients. The COVID-19 pandemic and its associated impacts on trade (including supply chains and export levels), travel, employee productivity, unemployment, consumer spending, and other economic activities has resulted in less economic activity, lower equity market valuations and significant volatility and disruption in financial markets and has had an adverse effect on the Company’s business, financial condition and results of operations. The ultimate extent of the impact of the COVID-19 pandemic on the Company’s business, financial condition and results of operations is currently uncertain and will depend on various developments and other factors, including, among others, the duration and scope of the pandemic, as well as governmental, regulatory and private sector responses to the pandemic, and the associated impacts on the economy, financial markets, and our clients, employees, and vendors. The Company’s business, financial condition and results of operations generally rely upon the ability of the Company’s borrowers to repay their loans, the value of collateral underlying the Company’s secured loans, and demand for loans and other products and services the Company offers, which are highly dependent on the business environment in the Company’s primary markets where it operates and in the United States as a whole. During 2020, the Company’s results of operations were negatively impacted by full impairment of the Company's goodwill, an increase in its provision for credit losses and related allowance for credit losses, a decline in the fair value of its equity portfolio, and a decline in valuation of assets. These circumstances could cause the Company to experience a material adverse effect on our business operations, asset valuations, financial condition, results of operations and prospects. Material adverse impacts may include all or a combination of valuation impairments on the Company’s intangible assets, investments, loans, loan servicing rights, deferre d tax assets, lease right-of-use assets, or counter-party risk derivatives. Beginning in March 2020, the Company has offered three-month payment deferrals for customers with a current payment status who were negatively impacted by economic disruption caused by the COVID-19 pandemic. As of December 31, 2021, the Company had modified 19 loans with a carrying value of $14.4 million. As of December 31, 2020, the Company had 746 active modified loans outstanding with a carrying value of $316.1 million, which excluded loans returning to payment or awaiting evaluation for further deferral. The Company continues to accrue interest on these loans during the deferral period. In accordance with interagency guidance issued in March 2020 and Section 4013 (Temporary Relief from Troubled Debt Restructurings) of the CARES Act, these short-term deferrals are not considered troubled debt restructurings (“TDRs”) unless the borrower was previously experiencing financial difficulty. In addition, the risk-ratings on COVID-19 modified loans did not automatically change as a result of payment deferrals, and these loans will not be considered past due until after the deferral period is over and scheduled payments resume. Credit Related Financial Instruments. The Company is a party to financial instruments with off-balance-sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit and standby letters of credit. Such commitments involve, to varying degrees, elements of credit, and interest rate risk in excess of the amount recognized in the accompanying Consolidated Balance Sheets. The Company’s exposure to credit loss in the event of non-performance by the other party to the financial instrument is represented by the contractual amount of these commitments. The Company uses the same credit policies in making commitments as it does for on-balance-sheet instruments. A summary of financial instruments outstanding whose contract amounts represent credit risk is as follows at year-end: (In thousands) 2021 2020 Commitments to originate new loans $ 588,034 $ 211,485 Unused funds on commercial and other lines of credit 902,598 944,678 Unadvanced funds on home equity lines of credit 334,784 371,080 Unadvanced funds on construction and real estate loans 340,336 226,736 Standby letters of credit 14,475 24,501 Total $ 2,180,227 $ 1,778,480 Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. The commitments for lines of credit may expire without being drawn upon. Therefore, the total commitment amounts do not necessarily represent future cash requirements. The Company evaluates each customer’s creditworthiness on a case-by-case basis. Standby letters of credit are conditional commitments issued by the Company to guarantee the performance of a customer to a third party. These letters of credit are primarily issued to support borrowing arrangements. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to customers. The Company considers standby letters of credit to be guarantees and the amount of the recorded liability related to such guarantees was not material at year-end 2021 and 2020. Employment and Change in Control Agreements. The Company and the Bank have change in control agreements with several officers which provide a severance payment in the event employment is terminated in conjunction with a defined change in control.

Stockholders' Equity Note [Abstract]
SHAREHOLDERS' EQUITY AND EARNINGS PER COMMON SHARE	SHAREHOLDERS’ EQUITY AND EARNINGS PER COMMON SHARE Minimum Regulatory Capital Requirements The Company and Bank are subject to various regulatory capital requirements administered by the federal and state banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by regulators that, if imposed, could have a direct material impact on the Company’s Consolidated Financial Statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Company and Bank must meet specific capital guidelines that involve quantitative measures of its assets, liabilities and certain off-balance-sheet items as calculated under regulatory accounting practices. The capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weighting and other factors. Quantitative measures established by regulation to ensure capital adequacy require the Company and Bank to maintain minimum amounts and ratios (set forth in the following table) of total and Tier 1 capital (as defined in the regulations) to risk-weighted assets (as defined) and of Tier 1 capital to average assets (as defined). As of year-end 2021 and 2020, the Bank and the Company met the capital adequacy requirements. Regulators may set higher expected capital requirements in some cases based on their examinations. At December 31, 2021, the capital levels of both the Company and the Bank exceeded all regulatory capital requirements and their regulatory capital ratios were above the minimum levels. The capital levels of both the Company and the Bank at December 31, 2021 also exceeded the minimum capital requirements including the currently applicable BASEL III capital conservation buffer of 1.875%. As of year-end 2021 and 2020, the Bank met the conditions to be classified as “well capitalized” under the relevant regulatory framework. To be categorized as well capitalized, an institution must maintain minimum total risk-based, Tier 1 risk-based, and Tier 1 leverage ratios as set forth in the following tables. The Company and Bank’s actual and required capital amounts were as follows: Minimum Actual (Dollars in thousands) Amount Ratio Amount Ratio December 31, 2021 Company (Consolidated) Total capital to risk-weighted assets $ 1,359,470 17.32 % $ 628,026 8.00 % Common Equity Tier 1 Capital to risk weighted assets 1,178,497 15.01 353,265 4.50 Tier 1 capital to risk-weighted assets 1,200,732 15.30 471,020 6.00 Tier 1 capital to average assets 1,200,732 10.49 314,013 4.00 Total risk-weighted assets 7,850,331 N/A N/A N/A December 31, 2020 Company (Consolidated) Total capital to risk-weighted assets $ 1,337,008 16.10 % $ 664,239 8.00 % Common Equity Tier 1 Capital to risk weighted assets 1,145,329 13.79 373,634 4.50 Tier 1 capital to risk-weighted assets 1,167,512 14.06 498,179 6.00 Tier 1 capital to average assets 1,167,512 9.38 332,119 4.00 Total risk-weighted assets 8,302,987 N/A N/A N/A Minimum Minimum to be Well Actual (Dollars in thousands) Amount Ratio Amount Ratio Amount Ratio December 31, 2021 Bank Total capital to risk-weighted assets $ 1,244,604 15.87 % $ 627,478 8.00 % $ 784,348 10.00 % Common Equity Tier 1 Capital to risk weighted assets 1,160,458 14.80 35,956 4.50 509,826 6.50 Tier 1 capital to risk-weighted assets 1,160,458 14.80 470,609 6.00 627,478 8.00 Tier 1 capital to average assets 1,160,458 10.13 313,739 4.00 392,174 5.00 Total risk-weighted assets 7,843,477 N/A N/A N/A N/A N/A December 31, 2020 Bank Total capital to risk-weighted assets $ 1,243,287 14.99 % $ 663,429 8.00 % $ 961,659 10.00 % Common Equity Tier 1 Capital to risk weighted assets 1,148,205 13.85 373,179 4.50 625,079 6.50 Tier 1 capital to risk-weighted assets 1,148,205 13.85 497,572 6.00 769,327 8.00 Tier 1 capital to average assets 1,148,205 9.23 331,715 4.00 480,830 5.00 Total risk-weighted assets 8,292,863 N/A N/A N/A N/A N/A Common stock The Bank is subject to dividend restrictions imposed by various regulators, including a limitation on the total of all dividends that the Bank may pay to the Company in any calendar year. The total of all dividends shall not exceed the Bank’s net income for the current year (as defined by statute), plus the Bank’s net income retained for the two previous years, without regulatory approval. Dividends from the Bank are an important source of funds to the Company to make dividend payments on its common and preferred stock, to make payments on its borrowings, and for its other cash needs. The ability of the Company and the Bank to pay dividends is dependent on regulatory policies and regulatory capital requirements. The ability to pay such dividends in the future may be adversely affected by new legislation or regulations, or by changes in regulatory policies relating to capital, safety and soundness, and other regulatory concerns. The payment of dividends by the Company is subject to Delaware law, which generally limits dividends to an amount equal to an excess of the net assets of a company (the amount by which total assets exceed total liabilities) over statutory capital, or if there is no excess, to the Company’s net profits for the current and/or immediately preceding fiscal year.

Diluted EPS reflects the potential dilution that could occur if securities or other contracts to issue common stock (such as stock options) were exercised or converted into additional common shares that would then share in the earnings of the entity. Diluted EPS is computed by dividing net income applicable to common stock by the weighted average number of common shares outstanding for the year, plus an incremental number of common-equivalent shares computed using the treasury stock method. Earnings/(loss) per common share has been computed based on the following (average diluted shares outstanding is calculated using the treasury stock method): Years Ended December 31, (In thousands, except per share data) 2021 2020 2019 Net income/(loss) from continuing operations $ 118,664 $ (513,175) $ 101,521 Net (loss) from discontinued operations — (19,842) (4,071) Net income/(loss) $ 118,664 $ (533,017) $ 97,450 Average number of common shares issued 51,903 51,903 49,782 Less: average number of treasury shares 1,951 1,569 1,142 Less: average number of unvested stock award shares 712 505 420 Plus: average participating preferred shares — 441 1,043 Average number of basic common shares outstanding 49,240 50,270 49,263 Plus: dilutive effect of unvested stock award shares 309 — 122 Plus: dilutive effect of stock options outstanding 5 — 36 Average number of diluted common shares outstanding 49,554 50,270 49,421 Basic earnings/(loss) per share: Continuing Operations $ 2.41 $ (10.21) $ 2.06 Discontinued operations — (0.39) (0.08) Basic earnings/(loss) per common share $ 2.41 $ (10.60) $ 1.98 Diluted earnings/(loss) per share: Continuing Operations $ 2.39 $ (10.21) $ 2.05 Discontinued operations — (0.39) (0.08) Diluted earnings/(loss) per common share $ 2.39 $ (10.60) $ 1.97 For the year ended 2021, 88 thousand options were anti-dilutive and therefore excluded from the earnings per share calculations. Due to the net loss in 2020, all unvested restricted stock and options were considered anti-dilutive and therefore excluded from the earnings per share calculations. For the year ended 2019, 61 thousand options were anti-dilutive and therefore excluded from the earnings per share calculations.

A total of 1.0 million shares was authorized under the Plan. Awards may be granted as either Restricted Stock or Stock Options provided that any shares that are granted as Restricted Stock are counted against the share limit set forth as (1) one for every one share of Restricted Stock granted and (2) one for every one share of Stock Option granted. As of the 2018 Plan's effective date, all expired, canceled, and forfeited shares under the 2013 Plan are included in the 2018 Plan's available shares. As of year-end 2021, the Company had the ability to grant approximately 0.5 million shares under this plan. A summary of activity in the Company’s stock compensation plans is shown below: Non-vested Stock Stock Options Outstanding (Shares in thousands) Number of Shares Weighted- Average Number of Shares Weighted- Average Exercise Price Balance, December 31, 2020 517 $ 28.35 112 $ 22.95 Granted 476 20.22 — — Acquired — — — — Stock options exercised — — (20) 20.66 Stock awards vested (170) 24.75 — — Forfeited (113) 23.48 (2) 24.71 Expired — — (10) 17.46 Balance, December 31, 2021 710 $ 20.16 80 $ 25.21 Stock Awards The total compensation cost for stock awards recognized as expense was $4.2 million, $4.7 million, and $4.8 million, in the years 2021, 2020, and 2019, respectively. The total recognized tax benefit associated with this compensation cost was $1.0 million, $1.2 million, and $1.3 million, respectively. The weighted average fair value of stock awards granted was $20.22, $16.69, and $29.47 in 2021, 2020, and 2019, respectively. Stock awards vest over periods up to five years and are valued at the closing price of the stock on the grant date. Certain awards vest based on the Company's performance over established measurement periods. The total fair value of stock awards vested during 2021, 2020, and 2019 was $4.3 million, $5.2 million, and $4.8 million respectively. The unrecognized stock-based compensation expense related to unvested stock awards was $9.1 million as of year-end 2021. This amount is expected to be recognized over a weighted average period of two years. Option Awards Option awards are granted with an exercise price equal to the market price of the Company’s stock at the date of grant, and vest over periods up to five years. The options grant the holder the right to acquire a share of the Company’s common stock for each option held, and have a contractual life of ten years. As of year-end 2021, the weighted average remaining contractual term for options outstanding is three years. The Company generally issues shares from treasury stock as options are exercised. The fair value of each option grant is estimated on the date of grant using the Black-Scholes option-pricing model. The expected dividend yield and expected term are based on management estimates. The expected volatility is based on historical volatility. The risk-free interest rates for the expected term are based on the U.S. Treasury yield curve in effect at the time of the grant. The Company did not grant options during 2021 and 2020. The Company acquired options in the SI Financial Group transaction in 2019, but did not grant additional options during 2019.

Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENTS	FAIR VALUE MEASUREMENTS A description of the valuation methodologies used for instruments measured at fair value, as well as the general classification of such instruments pursuant to the valuation hierarchy, is set forth below. These valuation methodologies were applied to all of the Company’s financial assets and financial liabilities that are carried at fair value, including assets classified as discontinued operations on the consolidated balance sheets. Recurring Fair Value Measurements of Financial Instruments The following table summarizes assets and liabilities measured at fair value on a recurring basis as of year-end 2021 and 2020 segregated by the level of the valuation inputs within the fair value hierarchy utilized to measure fair value: December 31, 2021 (In thousands) Level 1 Level 2 Level 3 Total Trading security $ — $ — $ 8,354 $ 8,354 Available-for-sale securities: Municipal bonds and obligations — 77,177 — 77,177 Agency collateralized mortgage obligations — 688,336 — 688,336 Agency residential mortgage-backed securities — 705,859 — 705,859 Agency commercial mortgage-backed securities — 282,334 — 282,334 Corporate bonds — 41,630 4,030 45,660 Other bonds and obligations — 78,219 — 78,219 Marketable equity securities 14,798 655 — 15,453 Loans held for investment — — 1,200 1,200 Loans held for sale — 6,110 — 6,110 Derivative assets — 79,270 258 79,528 Capitalized servicing rights — — 1,966 1,966 Derivative liabilities — 35,194 — 35,194 December 31, 2020 (In thousands) Level 1 Level 2 Level 3 Total Trading security $ — $ — $ 9,708 $ 9,708 Available-for-sale securities: Municipal bonds and obligations — 97,803 — 97,803 Agency collateralized mortgage obligations — 756,826 — 756,826 Agency residential mortgage-backed securities — 438,132 — 438,132 Agency commercial mortgage-backed securities — 288,650 — 288,650 Corporate bonds — 45,030 15,000 60,030 Other bonds and obligations — 53,791 — 53,791 Marketable equity securities 17,841 672 — 18,513 Loans held for investment — — 2,265 2,265 Loans held for sale — 12,992 4,756 17,748 Derivative assets — 159,016 1,055 160,071 Capitalized servicing rights — — 3,033 3,033 Derivative liabilities — 65,758 — 65,758 During the year ended December 31, 2021, the Company had one transfer totaling $4.0 million in corporate bonds from Level 2 to Level 3 based on recent inactivity in the market related to pricing information for similar bonds. During the year ended December 31, 2020, there were no transfers between Level 1, 2 and 3. During the year ended December 31, 2019, the Company had four transfers totaling $44.0 million in corporate bonds from Level 2 to Level 3 based on recent inactivity in the market related to pricing information for similar bonds. Trading Security at Fair Value. The Company holds one security designated as a trading security. It is a tax advantaged economic development bond issued to the Company by a local nonprofit which provides wellness and health programs. The determination of the fair value for this security is determined based on a discounted cash flow methodology. Certain inputs to the fair value calculation are unobservable and there is little to no market activity in the security; therefore, the security meets the definition of a Level 3 security. The discount rate used in the valuation of the security is sensitive to movements in the 3-month LIBOR rate. Securities Available for Sale and Marketable Equity Securities . Marketable equity securities classified as Level 1 consist of publicly-traded equity securities for which the fair values can be obtained through quoted market prices in active exchange markets. Marketable equity securities classified as Level 2 consist of securities with infrequent trades in active exchange markets, and pricing is primarily sourced from third party pricing services. AFS securities classified as Level 2 include most of the Company’s debt securities. The pricing on Level 2 and Level 3 was primarily sourced from third party pricing services, overseen by management, and is based on models that consider standard input factors such as dealer quotes, market spreads, cash flows, the U.S. Treasury yield curve, live trading levels, trade execution data, market consensus prepayment speeds, credit information and the bond’s terms and condition, among other things. Level 3 pricing includes inputs unobservable to market participants. Loans Held for Investment. The Company’s held for investment loan portfolio includes loans originated by Company and loans acquired through business combinations. The Company intends to hold these assets until maturity as a part of its business operations. For one acquired portfolio subset, the Company previously accounted for these purchased-credit impaired loans as a pool under ASC 310, as they were determined to have common risk characteristics. These loans were recorded at fair value on acquisition date and subsequently evaluated for impairment collectively. Upon adoption of ASC 326, the Company elected the fair value option on this portfolio, recognizing a $11.2 million fair value write-down charged to Retained Earnings, net of deferred tax impact, as of January 1, 2020. The fair value of this loan portfolio is determined based on a discounted cash flow methodology. Certain inputs to the fair value calculation are unobservable; therefore, the loans meet the definition of Level 3 assets. The discount rate used in the valuation is consistent with assets that have significant credit deterioration. The cash flow assumptions include payment schedules for loans with current payment histories and estimated collateral value for delinquent loans. All of these loans were nonperforming as of December 31, 2021. Aggregate Fair Value December 31, 2021 Aggregate Aggregate Less Aggregate (In thousands) Fair Value Unpaid Principal Unpaid Principal Loans held for investment at fair value $ 1,200 $ 31,430 $ (30,230) Aggregate Fair Value December 31, 2020 Aggregate Aggregate Less Aggregate (In thousands) Fair Value Unpaid Principal Unpaid Principal Loans held for investment at fair value $ 2,265 $ 53,945 $ (51,680) Loans held for sale. The Company elected the fair value option for all mortgage loans originated for sale (HFS) that were originated for sale on or after May 1, 2012. Loans HFS are classified as Level 2 as the fair value is based on input factors such as quoted prices for similar loans in active markets. Aggregate Aggregate Aggregate Fair Value December 31, 2021 (In thousands) Loans held for sale $ 6,110 $ 5,926 $ 184 Aggregate Aggregate Aggregate Fair Value December 31, 2020 (In thousands) Loans held for sale $ 12,992 $ 12,639 $ 353 The changes in fair value of loans held for sale for the year ended December 31, 2021 were losses of $169 thousand. The changes in fair value of loans held for sale for the year ended December 31, 2020 were gains of $97 thousand from continuing operations and losses of $138 thousand from discontinued operations. During 2021, originations of loans held for sale totaled $104 million and sales of loans originated for sale totaled $108 million. During 2020, originations of loans held for sale from continuing operations totaled $150 million and sales of loans originated for sale from continuing operations totaled $141 million. During 2020, originations of loans held for sale from discontinued operations totaled $624.0 billion and sales of loans originated for sale from discontinued operations totaled $755.0 billion. Interest Rate Swaps. The valuation of the Company’s interest rate swaps is obtained from a third-party pricing service and is determined using a discounted cash flow analysis on the expected cash flows of each derivative. The pricing analysis is based on observable inputs for the contractual terms of the derivatives, including the period to maturity and interest rate curves. The Company incorporates credit valuation adjustments to appropriately reflect both its own nonperformance risk and the respective counterparty’s nonperformance risk in the fair value measurements. In adjusting the fair value of its derivative contracts for the effect of nonperformance risk, the Company has considered the impact of netting and any applicable credit enhancements, such as collateral postings. Although the Company has determined that the majority of the inputs used to value its interest rate derivatives fall within Level 2 of the fair value hierarchy, the credit valuation adjustments associated with its derivatives utilize Level 3 inputs, such as estimates of current credit spreads to evaluate the likelihood of default by itself and its counterparties. However, as of year-end 2021, the Company has assessed the significance of the impact of the credit valuation adjustments on the overall valuation of its derivative positions and has determined that the credit valuation adjustments are not significant to the overall valuation of its derivatives. As a result, the Company has determined that its derivative valuations in their entirety are classified in Level 2 of the fair value hierarchy. Commitments to Lend. The Company enters into commitments to lend for residential mortgage loans intended for sale, which commit the Company to lend funds to a potential borrower at a certain interest rate and within a specified period of time. The estimated fair value of commitments to originate residential mortgage loans for sale is based on quoted prices for similar loans in active markets. However, this value is adjusted by a factor which considers the likelihood that the loan commitment will ultimately close, and by the non-refundable costs of originating the loan. The closing ratio is derived from the Bank’s internal data and is adjusted using significant management judgment. The costs to originate are primarily based on the Company’s internal commission rates that are not observable. As such, these commitments to lend are classified as Level 3 measurements. Commitments to lend are included in discontinued operations. Forward Sale Commitments . The Company utilizes forward sale commitments as economic hedges against potential changes in the values of the commitments to lend and loans originated for sale. To be announced (TBA) mortgage-backed securities forward commitment sales are used as hedging instruments, are classified as Level 1, and consist of publicly-traded debt securities for which identical fair values can be obtained through quoted market prices in active exchange markets. The fair values of the Company’s best efforts and mandatory delivery loan sale commitments are determined similarly to the commitments to lend using quoted prices in the market place that are observable. However, costs to originate and closing ratios included in the calculation are internally generated and are based on management’s judgment and prior experience, which are considered factors that are not observable. As such, best efforts and mandatory forward sale commitments are classified as Level 3 measurements. Forward sale commitments are included in discontinued operations. Capitalized Servicing Rights. The Company accounts for certain capitalized servicing rights at fair value in its Consolidated Financial Statements, as the Company is permitted to elect the fair value option for each specific instrument. A loan servicing right asset represents the amount by which the present value of the estimated future net cash flows to be received from servicing loans exceed adequate compensation for performing the servicing. The fair value of servicing rights is estimated using a present value cash flow model. The most important assumptions used in the valuation model are the anticipated rate of the loan prepayments and discount rates. Although some assumptions in determining fair value are based on standards used by market participants, some are based on unobservable inputs and therefore are classified in Level 3 of the valuation hierarchy. The table below presents the changes in Level 3 assets that were measured at fair value on a recurring basis at year-end 2021 and 2020: Assets (Liabilities) (In thousands) Trading Securities Available for Sale Loans Held for Investment Commitments to Lend (1) Forward Capitalized Servicing Rights (1) Balance as of December 31, 2019 $ 10,769 $ 42,966 $ — $ 2,628 $ — $ 12,299 Adoption of ASC 326 — — 7,660 — — — Maturities, calls, and prepayments of AFS Security — (30,000) — — — — Unrealized (loss) gain, net recognized in other non-interest income (327) — (1,283) — — (822) Unrealized gain/(loss), net recognized in discontinued — — — 16,565 320 (8,444) Unrealized (loss) included in accumulated other comprehensive loss — 2,034 — — — — Transfers to Level 3 — — — — — — Paydown of asset (734) — (4,112) — — — Transfers to loans held for sale — — — (18,458) — — Additions to servicing rights — — — — — — Balance as of December 31, 2020 $ 9,708 $ 15,000 $ 2,265 $ 735 $ 320 $ 3,033 Maturities, calls, and prepayments of AFS Security — (15,000) — — — Unrealized (loss) gain, net recognized in other non-interest income (578) — 1,645 1,995 (186) (1,067) Unrealized gain included in accumulated other comprehensive loss — 30 — — — — Transfers to Level 3 — 4,000 — — — — Paydown of asset (776) — (2,710) — — — Transfers to loans held for sale — — (2,606) — — Additions to servicing rights — — — — — Balance as of December 31, 2021 $ 8,354 $ 4,030 $ 1,200 $ 124 $ 134 $ 1,966 Unrealized gains/(losses) relating to instruments still held at December 31, 2021 $ 475 $ 30 $ — $ 124 $ 134 $ — Unrealized gains/(losses) relating to instruments still held at December 31, 2020 $ 1,053 $ 287 $ — $ 735 $ 320 $ — (1) For 2019, these assets were classified as assets from discontinued operations on the consolidated balance sheets.

There were no Level 1 or Level 2 nonrecurring fair value measurements for year-end 2021 and 2020. Individually evaluated loans. Loans are generally not recorded at fair value on a recurring basis. Periodically, the Company records non-recurring adjustments to the carrying value of loans based on fair value measurements for partial charge-offs of the uncollectible portions of those loans. Non-recurring adjustments can also include certain impairment amounts for collateral-dependent loans calculated when establishing the allowance for credit losses. Such amounts are generally based on the fair value of the underlying collateral supporting the loan and, as a result, the carrying value of the loan less the calculated valuation does not necessarily represent the fair value of the loan. Real estate collateral is typically valued using appraisals or other indications of value based on recent comparable sales of similar properties or assumptions generally observable in the marketplace. However, the choice of observable data is subject to significant judgment, and there are often adjustments based on judgment in order to make observable data comparable and to consider the impact of time, the condition of properties, interest rates, and other market factors on current values. Additionally, commercial real estate appraisals frequently involve discounting of projected cash flows, which relies inherently on unobservable data. Therefore, real estate collateral related nonrecurring fair value measurement adjustments have generally been classified as Level 3. Estimates of fair value for other collateral that supports commercial loans are generally based on assumptions not observable in the marketplace and therefore such valuations have been classified as Level 3. Capitalized loan servicing rights . A loan servicing right asset represents the amount by which the present value of the estimated future net cash flows to be received from servicing loans exceed adequate compensation for performing the servicing. The fair value of servicing rights is estimated using a present value cash flow model. The most important assumptions used in the valuation model are the anticipated rate of the loan prepayments and discount rates. Adjustments are only recorded when the discounted cash flows derived from the valuation model are less than the carrying value of the asset. Although some assumptions in determining fair value are based on standards used by market participants, some are based on unobservable inputs and therefore are classified in Level 3 of the valuation hierarchy. Summary of Estimated Fair Values of Financial Instruments The following tables summarize the estimated fair values, which represent exit price, and related carrying amounts, of the Company’s financial instruments. Certain financial instruments and all non-financial instruments are excluded from disclosure requirements. Accordingly, the aggregate fair value amounts presented herein may not necessarily represent the underlying fair value of the Company. Certain assets and liabilities in the following disclosures include balances classified as discontinued operations.

REVENUE

REVENUE	12 Months Ended

Revenue from Contract with Customer [Abstract]
REVENUE	REVENUE Revenue from contracts with customers in the scope of Topic 606 is recognized within noninterest income. The Company does not have any material significant payment terms as payment is received at or shortly after the satisfaction of the performance obligation. The value of unsatisfied performance obligations for contracts with an original expected length of one year or less are not disclosed. The Company recognizes incremental costs of obtaining contracts as an expense when incurred for contracts with a term of one year or less. Topic 606 does not apply to revenue associated with financial instruments, including revenue from loans and securities. In addition, certain non-interest income streams such as fees associated with mortgage servicing rights, financial guarantees, derivatives, and certain credit card fees are also not in scope of Topic 606. Topic 606 is applicable to non-interest revenue streams such as wealth management fees, insurance commissions and fees, administrative services for customer deposit accounts, interchange fees, and sale of owned real estate properties. The following presents non-interest income, segregated by revenue streams in-scope and out-of-scope of Topic 606, for the years ended 2021, 2020, and 2019, respectively. Years Ended December 31, (In thousands) 2021 2020 2019 Non-interest income In-scope of Topic 606: Service charges on deposit accounts $ 20,249 $ 19,239 $ 23,122 Insurance commissions and fees 7,003 10,770 10,957 Wealth management fees 10,530 9,285 9,353 Interchange income 8,321 7,559 6,266 Non-interest income (in-scope of Topic 606) $ 46,103 $ 46,853 $ 49,698 Non-interest income (out-of-scope of Topic 606) 97,145 19,454 34,304 Total non-interest income from continuing operations $ 143,248 $ 66,307 $ 84,002 Non-interest income streams in-scope of Topic 606 are discussed below. Service Charges on Deposit Accounts. Service charges on deposit accounts consist of monthly service fees (i.e. business analysis fees and consumer service charges) and other deposit account related fees. The Company's performance obligation for monthly service fees is generally satisfied, and the related revenue recognized, over the period in which the service is provided. Other deposit account related fees are largely transactional based, and therefore, the Company's performance obligation is satisfied, and related revenue recognized, at a point in time. Payment for service charges on deposit accounts is primarily received immediately or in the following month through a direct charge to customers’ accounts. The Company may, from time to time, waive certain fees (e.g., NSF fee) for customers but generally do not reduce the transaction price to reflect variability for future reversals due to the insignificance of the amounts. Waiver of fees reduces the revenue in the period the waiver is granted to the customer. Insurance Commissions and Fees. Commission revenue is recognized as of the effective date of the insurance policy or the date the customer is billed, whichever is later, net of return commissions related to policy cancellations. Policy cancellation is a variable consideration that is not deemed significant and thus, does not impact the amount of revenue recognized. In addition, the Company may receive additional performance commissions based on achieving certain sales and loss experience measures. Such commissions are recognized when determinable, which is generally when such commissions are received or when the Company receives data from the insurance companies that allows the reasonable estimation of these amounts. Wealth Management Fees. Wealth management fees are primarily comprised of fees earned from consultative investment management, trust administration, tax return preparation, and financial planning. The Company’s performance obligation is generally satisfied over time and the resulting fees are recognized monthly, based on the daily accrual of the market value of the investment accounts and the applicable fee rate. Interchange Fees. Interchange fees are transaction fees paid to the card-issuing bank to cover handling costs, fraud and bad debt costs, and the risk involved in approving the payment. Due to the day-to-day nature of these fees they are settled on a daily basis and are accounted for as they are received. Gains/Losses on Sales of OREO. The sale of OREO and other nonfinancial assets are accounted for with the derecognition of the asset in question once a contract exists and control of the asset has been transferred to the buyer. The gain or loss on the sale is calculated as the difference between the carrying value of the asset and the transaction price.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICES (Policies)	12 Months Ended

Accounting Policies [Abstract]
Basis of Presentation and Consolidation	Basis of Presentation and Consolidation The Consolidated Financial Statements (the “financial statements”) of Berkshire Hills Bancorp, Inc. and its subsidiaries (the “Company” or “Berkshire”) have been prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”). The Company is a Delaware corporation, headquartered in Boston, Massachusetts, and the holding company for Berkshire Bank (the “Bank”), a Massachusetts-chartered trust company headquartered in Pittsfield, Massachusetts. These financial statements include the accounts of the Company, its wholly-owned subsidiaries and the Bank’s consolidated subsidiaries. In consolidation, all significant intercompany accounts and transactions are eliminated. The results of operations of companies or assets acquired are included only from the dates of acquisition. All material wholly-owned and majority-owned subsidiaries are consolidated unless GAAP requires otherwise. The Company has evaluated subsequent events for potential recognition and/or disclosure through the date these financial statements were issued.
Reclassifications	Reclassifications Certain items in prior financial statements have been reclassified to conform to the current presentation.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent liabilities at the date of the financial statements. Actual results could differ from those estimates. Refer to Note 18 – Other Commitments, Contingencies, and Off-Balance Sheet Activities for pandemic related risks and uncertainties.
Business Combinations	Business Combinations Business combinations are accounted for using the acquisition method of accounting. Under this method, the accounts of an acquired entity are included with the acquirer’s accounts as of the date of acquisition with any excess of purchase price over the fair value of the net assets acquired (including identifiable intangibles) capitalized as goodwill. To consummate an acquisition, the Company will typically issue common stock and/or pay cash, depending on the terms of the acquisition agreement. The value of common shares issued is determined based upon the market price of the stock as of the closing of the acquisition.
Cash and Cash equivalents	Cash and Cash equivalents Cash and cash equivalents include cash, balances due from banks, and short-term investments, all of which had an original maturity within 90 days. Due to the nature of cash and cash equivalents and the near term maturity, the Company estimated that the carrying amount of such instruments approximated fair value. The nature of the Bank’s business requires that it maintain amounts due from banks which at times, may exceed federally insured limits. The Bank has not experienced any losses on such amounts and all amounts are maintained with well-capitalized institutions.
Trading Security	Trading Security The Company accounts for a tax advantaged economic development bond originated in 2008 at fair value, in accordance with Financial Accounting Standards Board’s (“FASB”) Accounting Standards Codification (“ASC”) 320. The bond has been designated as a trading account security and is recorded at fair value, with changes in unrealized gains and losses recorded through earnings each period as part of non-interest income.
Securities	Securities Debt securities that management has the intent and ability to hold to maturity are classified as held to maturity and carried at amortized cost. All other debt securities are classified as available for sale and carried at fair value, with unrealized gains and losses reported as a component of other net comprehensive income. Equity securities are carried at fair value, with changes in fair value reported in net income. Management determines the appropriate classification of securities at the time of purchase. Restricted equity securities, such as stock in the Federal Home Loan Bank of Boston (“FHLBB”) are carried at cost. There are no quoted market prices for the Company’s restricted equity securities. The Bank is a member of the FHLBB, which requires that members maintain an investment in FHLBB stock, which may be redeemed based on certain conditions. The Bank reviews for impairment based on the ultimate recoverability of the cost bases in the FHLBB stock. Purchase premiums and discounts are recognized in interest income using the interest method, without anticipating prepayments, except mortgage-backed securities where prepayments are anticipated, over the terms of the securities. Premiums on callable debt securities are amortized to their earliest call date. Gains and losses on the sale of securities are recorded on the trade date and are determined using the specific identification method. The Company measures expected credit losses on held to maturity debt securities on a collective basis. Accrued interest receivable on held to maturity debt securities is excluded from the estimate of credit losses. The estimate of expected credit losses considers historical credit loss information that is adjusted for current conditions and reasonable and supportable forecasts.
Loans Held for Sale	Loans Held for Sale Loans originated with the intent to be sold in the secondary market are accounted for under the fair value option. Non-refundable fees and direct loan origination costs related to residential mortgage loans held for sale are recognized in non-interest income or non-interest expense as earned or incurred. Fair value is primarily determined based on quoted prices for similar loans in active markets. Gains and losses on sales of residential mortgage loans (sales proceeds minus carrying value) are recorded in non-interest income. Loans that were previously held for investment that the Company has an active plan to sell are transferred to loans held for sale at the lower of cost or market (fair value). The market price is primarily determined based on quoted prices for similar loans in active markets or agreed upon sales prices. Gains are recorded in non-interest income at sale to the extent that the sale price of the loan exceeds carrying value. Any reduction in the loan’s value, prior to being transferred to loans held for sale, is reflected as a charge-off of the recorded investment in the loan resulting in a new cost basis, with a corresponding reduction in the allowance for credit losses. Further decreases in the fair value of the loan are recognized in non-interest expense.
Loans	Loans Loans are reported at their amortized cost. Amortized cost is the principal balance outstanding, net of the unamortized balance of any deferred fees or costs and the unamortized balance of any premiums or discounts on loans purchased or acquired through mergers. Interest income is accrued on the unpaid principal balance. Interest income includes net accretion or amortization of deferred fees or costs and of premiums or discounts. Direct loan origination costs, net of any origination fees, in addition to premiums and discounts on loans, are deferred and recognized as an adjustment of the related loan yield using the interest method. Interest on loans, excluding automobile loans, is generally not accrued on loans which are ninety days or more past due unless the loan is well-secured and in the process of collection. Past due status is based on contractual terms of the loan. Automobile loans generally continue accruing until one hundred and twenty days delinquent, at which time they are charged off. All interest accrued but not collected for loans that are placed on non-accrual or charged-off is reversed against interest income, except for certain loans designated as well-secured. The interest on non-accrual loans is accounted for on the cash-basis or cost-recovery method, until qualifying for return to accrual. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured.
Purchase Credit Deteriorated (PCD) Loans	Purchase Credit Deteriorated (PCD) LoansLoans that the Company acquired in acquisitions include some loans that have experienced more than insignificant credit deterioration since origination. PCD loans are recorded at the amount paid. An allowance for credit losses is determined using the same methodology as other loans held for investment. The initial allowance for credit losses determined on a collective basis is allocated to individual loans. The sum of the loan’s purchase price and allowance for credit losses becomes its initial amortized cost basis. The difference between the initial amortized cost basis and the par value of the loan is a noncredit discount or premium, which is amortized into interest income over the life of the loan. Subsequent changes to the allowance for credit losses are recorded through provision expense
Allowance for Credit Losses for Loans	Allowance for Credit Losses for Loans The allowance for credit losses for loans (“ACLL”) is comprised of the allowance for loan losses and the allowance for unfunded commitments which is accounted for as a separate liability in other liabilities on the consolidated balance sheet. The ACLL is a valuation account that is deducted from the loans’ amortized cost basis to present the net amount expected to be collected on the loans. Loans are charged off against the allowance when management believes the uncollectibility of a loan balance is confirmed. Accrued interest receivable is excluded from the estimate of credit losses. The level of the ACLL represents management’s estimate of expected credit losses over the expected life of the loans at the balance sheet date. The Company uses a static pool migration analysis method, applying expected historical loss trend and observed economic metrics. The level of the ACLL is based on management’s ongoing review of all relevant information, from internal and external sources, relating to past and current events, utilizing a 7 quarter reasonable and supportable forecast period with a 1 year reversion period. The ACLL reserve is overlaid with qualitative factors based upon: • the existence and growth of concentrations of credit; • the volume and severity of past due financial assets, including nonaccrual assets; • the institutions lending and credit review as well as the experience and ability of relevant management and staff and; • the effect of other external factors such as regulatory, competition, regional market conditions, legal and technological environment and other events such as natural disasters; • the effect of other economic factors such as economic stimulus and customer forbearance programs. The allowance for unfunded commitments is maintained at a level by the Company to be sufficient to absorb expected lifetime losses related to unfunded credit facilities (including unfunded loan commitments and letters of credit). The ACLL is measured on a collective (pool) basis when similar risk characteristics exist. The Company evaluates its risk characteristics of loans based on regulatory call report code with sub-segmentation based on underlying collateral for certain loan types. Risk characteristics relevant to each portfolio segment are as follows: Construction – Loans in this segment primarily include real estate development loans for which payment is derived from sale of the property or long term financing at completion. Credit risk is affected by cost overruns, time to sell at an adequate price, and market conditions. Commercial real estate multifamily, owner occupied and non-owner – Loans in this segment are primarily owner-occupied or income-producing properties throughout New England and Northeastern New York. The underlying cash flows generated by the properties are adversely impacted by a downturn in the economy, which in turn, will have an effect on the credit quality in this segment. Management monitors the cash flows of these loans. Commercial and industrial loans – Loans in this segment are made to businesses and are generally secured by assets of the business such as accounts receivable, inventory, marketable securities, other liquid collateral, equipment and other business assets. Repayment is expected from the cash flows of the business. Loans in this segment include asset based loans which generally have no scheduled repayment which are closely monitored against formula based collateral advance ratios. A weakened economy, and resultant decreased consumer spending, will have an effect on the credit quality of this segment. Residential real estate – All loans in this segment are collateralized by residential real estate and repayment is dependent on the credit quality of the individual borrower. The overall health of the economy, including unemployment rates and housing prices, will have an effect on the credit quality in this segment. Home equity and other consumer loans – Loans in this segment are primarily home equity lines of credit, automobile loans and other consumer loans. The overall health of the economy, including unemployment rates and housing prices, will have an effect on the credit quality in this segment. Loans that do not share risk characteristics are evaluated on an individual basis, which the Company has determined to be non-accrual loans over a certain threshold, loans that were determined to be Troubled Debt Restructurings (“TDRs”) and PCD loans. Loans evaluated individually are not also included in the collective evaluation. Estimates of specific allowance may be determined by the present value of anticipated future cash flows or the loan’s observable fair market value, or the fair value of the collateral less costs to sell, if the loan is collateral dependent. However, for collateral dependent loans, the amount of the amortized cost in a loan that exceeds the fair value of the collateral is charged-off against the allowance for loan losses in lieu of an allocation of a specific allowance amount when such an amount has been identified definitively as uncollectible.
Bank-Owned Life Insurance	Bank-Owned Life Insurance Bank-owned life insurance policies are reflected on the Consolidated Balance Sheets at the amount that can be realized under the insurance contract at the balance sheet date which is the cash surrender value. Changes in the net cash surrender value of the policies, as well as insurance proceeds received, are reflected in non-interest income on the Consolidated Statements of Operations and are not subject to income taxes.
Foreclosed and Repossessed Assets	Foreclosed and Repossessed Assets Other real estate owned is comprised of real estate acquired through foreclosure proceedings or acceptance of a deed in lieu of foreclosure. Repossessed collateral is primarily comprised of taxi medallions. Both other real estate owned and repossessed collateral are held for sale and are initially recorded at the fair value less estimated costs to sell at the date of foreclosure or repossession, establishing a new cost basis. The shortfall, if any, of the loan balance over the fair value of the property or collateral (excluding taxi medallions), less cost to sell, at the time of transfer
Capitalized Servicing Rights	Capitalized Servicing Rights Capitalized servicing rights are included in “other assets” in the Consolidated Balance Sheets. Servicing assets are initially recognized as separate assets at fair value when rights are acquired through purchase or through sale of financial assets with servicing retained. The Company's servicing rights accounted for under the fair value method are carried on the Consolidated Balance Sheets at fair value with changes in fair value recorded in income in the period in which the change occurs. Changes in the fair value of servicing rights are primarily due to changes in valuation assumptions, such as discount rates and prepayment speeds, and the collection and realization of expected cash flows. The Company’s servicing rights accounted for under the amortization method are initially recorded at fair value. Under that method, capitalized servicing rights are charged to expense in proportion to and over the period of estimated net servicing income. Fair value of the servicing rights is based on a valuation model that calculates the present value of estimated future net servicing income. The valuation model incorporates assumptions that market participants would use in estimating future net servicing income, such as the cost to service, the discount rate, prepayment speeds and default rates and losses. Impairment is recognized through a valuation allowance for an individual tranche, to the extent that fair value is less than the capitalized amount for the tranches. If the Company later determines that all or a portion of the impairment no longer exists for a particular tranche, a reduction of the allowance may be recorded as an increase to income.
Premises and Equipment	Premises and Equipment Land is carried at cost. Buildings, improvements, and equipment are carried at cost less accumulated depreciation and amortization computed on the straight-line method over the estimated useful lives of the assets. Leasehold improvements are amortized on the straight-line method over the shorter of the lease term, plus optional terms if certain conditions are met, or the estimated useful life of the asset.
Goodwill	GoodwillGoodwill represents the excess of the purchase price over the fair value of the net assets acquired in a business combination. Goodwill is assessed annually for impairment, and more frequently if events or changes in circumstances indicate that there may be an impairment. Adverse changes in the economic environment, declining operations, unanticipated competition, loss of key personnel, or other factors could result in a decline in the implied fair value of goodwill. Subsequent reversals of goodwill impairment are prohibited.
Other Intangibles	Other Intangibles Intangible assets are acquired assets that lack physical substance but can be distinguished from goodwill because of contractual or other legal rights or the asset is capable of being sold or exchanged either on its own or in combination with a related contract, asset or liability. The fair values of these assets are generally determined based on appraisals and are subsequently amortized on a straight-line basis or an accelerated basis over their estimated lives. Management assesses the recoverability of these intangible assets at least annually or whenever events or changes in circumstances indicate that their carrying value may not be recoverable. If the carrying amount exceeds fair value, an impairment charge is recorded to income.
Transfers of Financial Assets	Transfers of Financial Assets Transfers of an entire financial asset, group of entire financial assets, or a participating interest in an entire financial asset are accounted for as sales when control over the assets has been surrendered. Control over transferred assets is deemed to be surrendered when (1) the assets have been isolated from the Company, (2) the transferee obtains the right to pledge or exchange the transferred assets, and (3) the Company does not maintain effective control over the transferred assets.
Income Taxes	Income Taxes Deferred income taxes are recognized for the tax consequences of temporary differences by applying enacted statutory tax rates applicable for future years to differences between financial statement and tax bases of existing assets and liabilities. The effect of tax rate changes on deferred taxes is recognized in the income tax provision in the period that includes the enactment date. A tax valuation allowance is established, as needed, to reduce net deferred tax assets to the amount expected to be realized. In the event it becomes more likely than not that some or all of the deferred tax asset allowances will not be needed, the valuation allowance will be adjusted. In the ordinary course of business there is inherent uncertainty in quantifying the Company’s income tax
Insurance Commissions	Insurance Commissions Commission revenue is recognized as of the effective date of the insurance policy or the date the customer is billed, whichever is later, net of return commissions related to policy cancellations. Policy cancellation is a variable consideration that is not deemed significant and thus, does not impact the amount of revenue recognized. In addition, the Company may receive additional performance commissions based on achieving certain sales and loss experience measures. Such commissions are recognized when determinable, which is generally when such commissions are received or when the Company receives data from the insurance companies that allows the reasonable estimation of these amounts. Revenue from contracts with customers in the scope of Topic 606 is recognized within noninterest income. The Company does not have any material significant payment terms as payment is received at or shortly after the satisfaction of the performance obligation. The value of unsatisfied performance obligations for contracts with an original expected length of one year or less are not disclosed. The Company recognizes incremental costs of obtaining contracts as an expense when incurred for contracts with a term of one year or less. Topic 606 does not apply to revenue associated with financial instruments, including revenue from loans and securities. In addition, certain non-interest income streams such as fees associated with mortgage servicing rights, financial guarantees, derivatives, and certain credit card fees are also not in scope of Topic 606. Topic 606 is applicable to non-interest revenue streams such as wealth management fees, insurance commissions and fees, administrative services for customer deposit accounts, interchange fees, and sale of owned real estate properties. The following presents non-interest income, segregated by revenue streams in-scope and out-of-scope of Topic 606, for the years ended 2021, 2020, and 2019, respectively. Years Ended December 31, (In thousands) 2021 2020 2019 Non-interest income In-scope of Topic 606: Service charges on deposit accounts $ 20,249 $ 19,239 $ 23,122 Insurance commissions and fees 7,003 10,770 10,957 Wealth management fees 10,530 9,285 9,353 Interchange income 8,321 7,559 6,266 Non-interest income (in-scope of Topic 606) $ 46,103 $ 46,853 $ 49,698 Non-interest income (out-of-scope of Topic 606) 97,145 19,454 34,304 Total non-interest income from continuing operations $ 143,248 $ 66,307 $ 84,002 Non-interest income streams in-scope of Topic 606 are discussed below. Service Charges on Deposit Accounts. Service charges on deposit accounts consist of monthly service fees (i.e. business analysis fees and consumer service charges) and other deposit account related fees. The Company's performance obligation for monthly service fees is generally satisfied, and the related revenue recognized, over the period in which the service is provided. Other deposit account related fees are largely transactional based, and therefore, the Company's performance obligation is satisfied, and related revenue recognized, at a point in time. Payment for service charges on deposit accounts is primarily received immediately or in the following month through a direct charge to customers’ accounts. The Company may, from time to time, waive certain fees (e.g., NSF fee) for customers but generally do not reduce the transaction price to reflect variability for future reversals due to the insignificance of the amounts. Waiver of fees reduces the revenue in the period the waiver is granted to the customer. Insurance Commissions and Fees. Commission revenue is recognized as of the effective date of the insurance policy or the date the customer is billed, whichever is later, net of return commissions related to policy cancellations. Policy cancellation is a variable consideration that is not deemed significant and thus, does not impact the amount of revenue recognized. In addition, the Company may receive additional performance commissions based on achieving certain sales and loss experience measures. Such commissions are recognized when determinable, which is generally when such commissions are received or when the Company receives data from the insurance companies that allows the reasonable estimation of these amounts. Wealth Management Fees. Wealth management fees are primarily comprised of fees earned from consultative investment management, trust administration, tax return preparation, and financial planning. The Company’s performance obligation is generally satisfied over time and the resulting fees are recognized monthly, based on the daily accrual of the market value of the investment accounts and the applicable fee rate. Interchange Fees. Interchange fees are transaction fees paid to the card-issuing bank to cover handling costs, fraud and bad debt costs, and the risk involved in approving the payment. Due to the day-to-day nature of these fees they are settled on a daily basis and are accounted for as they are received. Gains/Losses on Sales of OREO. The sale of OREO and other nonfinancial assets are accounted for with the derecognition of the asset in question once a contract exists and control of the asset has been transferred to the buyer. The gain or loss on the sale is calculated as the difference between the carrying value of the asset and the transaction price.
Stock-Based Compensation	Stock-Based Compensation The Company measures and recognizes compensation cost relating to share-based payment transactions based on the grant-date fair value of the equity instruments issued. The fair value of restricted stock is recorded as unearned compensation. The deferred expense is amortized to compensation expense based on one of several permitted attribution methods over the longer of the required service period or performance period. For performance-based restricted stock awards, the Company estimates the degree to which performance conditions will be met to determine the number of shares that will vest and the related compensation expense. Compensation expense is adjusted in the period such estimates change. Income tax benefits and/or tax deficiencies related to stock compensation determined as the difference between compensation cost recognized for financial reporting purposes and the deduction for tax, are recognized in the income statement as income tax expense or benefit in the period in which they occur.
Wealth Management	Wealth Management Wealth management assets held in a fiduciary or agent capacity are not included in the accompanying Consolidated Balance Sheets because they are not assets of the Company. Wealth management fees is primarily comprised of fees earned from consultative investment management, trust administration, tax return preparation, and financial planning. The Company’s performance obligation is generally satisfied over time and the resulting fees are recognized monthly, based on the daily accrual of the market value of the investment accounts and the applicable fee rate.
Derivative Instruments and Hedging Activities	Derivative Instruments and Hedging Activities The Company enters into interest rate swap agreements as part of the Company’s interest rate risk management strategy for certain assets and liabilities and not for speculative purposes. Based on the Company’s intended use for the interest rate swap at inception, the Company designates the derivative as either an economic hedge of an asset or liability or a hedging instrument subject to the hedge accounting provisions of ASC 815, “Derivatives and Hedging.” Interest rate swaps designated as economic hedges are recorded at fair value within other assets or liabilities. Changes in the fair value of these derivatives are recorded directly through earnings. For interest rate swaps that management intends to apply the hedge accounting provisions of ASC 815, the Company formally documents at inception all relationships between hedging instruments and hedged items, as well as its risk management objectives and strategies for undertaking the various hedges. Additionally, the Company uses dollar offset or regression analysis at the hedge’s inception and for each reporting period thereafter, to assess whether the derivative used in its hedging transaction is expected to be and has been highly effective in offsetting changes in the fair value or cash flows of the hedged item. The Company discontinues hedge accounting when it is determined that a derivative is not expected to be or has ceased to be highly effective as a hedge, and then reflects changes in fair value of the derivative in earnings after termination of the hedge relationship. The Company enters into commitments to lend with borrowers, and forward commitments to sell loans or to-be-announced mortgage-backed bonds to investors to hedge against the inherent interest rate and pricing risk associated with selling loans. The commitments to lend generally terminate once the loan is funded, the lock period expires or the borrower decides not to contract for the loan. The forward commitments generally terminate once the loan is sold, the commitment period expires or the borrower decides not to contract for the loan. These commitments are considered derivatives which are accounted for by recognizing their estimated fair value on the Consolidated Balance Sheets as either a freestanding asset or liability. See Note 15 - Derivative Instruments and Hedging Activities to the financial statements for more information on commitments to lend and forward commitments.
Off-Balance Sheet Financial Instruments	Off-Balance Sheet Financial Instruments In the ordinary course of business, the Company enters into off-balance sheet financial instruments, consisting primarily of credit related financial instruments. These financial instruments are recorded in the financial statements when they are funded or related fees are incurred or received.
Fair Value Hierarchy	Fair Value Hierarchy The Company groups assets and liabilities that are measured at fair value in three levels, based on the markets in which the assets and liabilities are traded and the reliability of the assumptions used to determine fair value. Level 1 - Valuation is based on quoted prices in active markets for identical assets or liabilities. Valuations are obtained from readily available pricing sources for market transactions involving identical assets or liabilities. Level 2 - Valuation is based on observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 3 - Valuation is based on unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. Level 3 assets and liabilities include financial instruments whose value is determined using unobservable techniques, as well as instruments for which the determination of fair value requires significant management judgment or estimation.
Employee Benefits	Employee Benefits The Company maintains an employer sponsored 401(k) plan to which participants may make contributions in the form of salary deferrals and the Company provides matching contributions in accordance with the terms of the plan. Contributions due under the terms of the defined contribution plans are accrued as earned by employees. Due to the Rome Bancorp acquisition in 2011, the Company inherited a noncontributory, qualified, defined benefit pension plan for certain employees who met age and service requirements; as well as other post-retirement benefits, principally health care and group life insurance. The Rome pension plan and postretirement benefits that were acquired in connection with the whole-bank acquisition were frozen prior to the close of the transaction. The pension benefit in the form of a life annuity is based on the employee’s combined years of service, age, and compensation. The Company also has a long-term care post-retirement benefit plan for certain executives where upon disability, associated benefits are funded by insurance policies or paid directly by the Company. In order to measure the expense associated with the Plans, various assumptions are made including the discount rate, expected return on plan assets, anticipated mortality rates, and expected future healthcare costs. The assumptions are based on historical experience as well as current facts and circumstances. The Company uses a December 31 measurement date for its plans. As of the measurement date, plan assets are determined based on fair value, generally representing observable market prices. The projected benefit obligation is primarily determined based on the present value of projected benefit distributions at an assumed discount rate. Net periodic pension benefit costs include interest costs based on an assumed discount rate, the expected return on plan assets based on actuarially derived market-related values, and the amortization of net actuarial losses. Net periodic postretirement benefit costs include service costs, interest costs based on an assumed discount rate, and the amortization of prior service credits and net actuarial gains. Differences between expected and actual results in each year are included in the net actuarial gain or loss amount, which is recognized in other comprehensive income. The net actuarial gain or loss in excess of a 10% corridor is amortized in net periodic benefit cost over the average remaining service period of active participants in the Plans. The prior service credit is amortized over the average remaining service period to full eligibility for participating employees expected to receive benefits. The Company recognizes in its statement of condition an asset for a plan’s overfunded status or a liability for a plan’s underfunded status. The Company also measures the Plans’ assets and obligations that determine its funded status as of the end of the fiscal year and recognizes those changes in other comprehensive income, net of tax.
Operating Segments	Operating Segments The Company operates as one consolidated reportable segment. The chief operating decision-maker evaluates consolidated results and makes decisions for resource allocation on this same data. Management periodically reviews and redefines its segment reporting as internal reporting practices evolve and components of the business change. The financial statements reflect the financial results of the Company's one reportable operating segment.
Recently Adopted Accounting Principles and Future Application of Accounting Pronouncements	Recently Adopted Accounting Principles In August 2018, the FASB issued ASU No. 2018-14, “Compensation - Retirement Benefits - Defined Benefit Plans - General (Subtopic 715-20): Disclosure Framework - Changes to the Disclosure Requirements for Defined Benefit Plans.” This ASU amends and modifies the disclosure requirements for employers that sponsor defined benefit pension or other post-retirement plans. The amendments in this update remove disclosures that no longer are considered cost beneficial, clarify the specific requirements of disclosures, and add disclosure requirements identified as relevant. As ASU No. 2018-14 only revises disclosure requirements, the adoption did not have a material impact on the Company’s Consolidated Financial Statements. In December 2019, the FASB issued ASU No. 2019-12, “Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes.” ASU No. 2019-12 removes specific exceptions to the general principles in FASB ASC Topic 740. It eliminates the need for an organization to analyze whether the following apply in a given period: (1) exception to the incremental approach for intraperiod tax allocation; (2) exceptions to accounting for basis differences when there are ownership changes in foreign investments; and (3) exception in interim period income tax accounting for year-to-date losses that exceed anticipated losses. ASU 2019-12 also improves financial statement preparers’ application of income tax-related guidance and simplifies: (1) franchise taxes that are partially based on income; (2) transactions with a government that result in a step up in the tax basis of goodwill; (3) separate financial statements of legal entities that are not subject to tax; and (4) enacted changes in tax laws in interim periods. The adoption of ASU No. 2019-12 did not have a material impact on the Company's Consolidated Financial Statements. In January 2020, the FASB issued ASU No. 2020-01, “Investments - Equity Securities (Topic 321), Investments - Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815): Clarifying the Interactions Between Topic 321, Topic 323, and Topic 815 (a consensus of the FASB Emerging Issues Task Force)”. ASU No. 2020-01 clarifies the interaction of the accounting for equity securities under Topic 321 and investments accounted for under the equity method of accounting in Topic 323 and the accounting for certain forward contracts and purchased options accounted for under Topic 815. The amendments clarify that an entity should consider observable transactions that require it to either apply or discontinue the equity method of accounting for the purposes of applying the measurement alternative in accordance with Topic 321 immediately before applying or upon discontinuing the equity method. In addition, this ASU provides direction that a company should not consider whether the underlying securities would be accounted for under the equity method or the fair value option when it is determining the accounting for certain forward contracts and purchased options, upon either settlement or exercise. The amendments are to be applied prospectively. The adoption of ASU No. 2020-01 did not have a material impact on the Company's Consolidated Financial Statements. In January 2021, the FASB issued ASU No. 2021-01, “Reference Rate Reform (Topic 848): Scope.” ASU No. 2021-01 clarifies that certain optional expedients and exceptions in ASC 848 for contract modifications and hedge accounting apply to derivatives that are affected by the discounting transition. ASU No. 2021-01 also amends the expedients and exceptions in ASC 848 to capture the incremental consequences of the scope clarification and to tailor the existing guidance to derivative instruments affected by the discounting transition. ASU No. 2021-01 was effective upon issuance and generally can be applied through December 31, 2022. The adoption of ASU 2021-01 did not significantly impact the Company’s Consolidated Financial Statements. Future Application of Accounting Pronouncements In March 2020, the FASB issued ASU No. 2020-04, “Facilitation of the Effects of Reference Rate Reform on Financial Reporting.” ASU No. 2020-04 provides temporary optional expedients and exceptions to GAAP guidance on contract modifications and hedge accounting to ease the financial reporting burdens of the expected market transition from LIBOR and other interbank offered rates to alternative reference rates, such as SOFR. For instance, entities can elect not to apply certain modification accounting requirements to contracts affected by reference rate reform, if certain criteria are met. An entity that makes this election would not have to remeasure the contracts at the modification date or reassess a previous accounting determination. Entities can also elect various optional expedients that would allow them to continue applying hedge accounting for hedging relationships affected by reference rate reform, if certain criteria are met. Finally, entities can make a one-time election to sell and/or reclassify held-to-maturity debt securities that reference an interest rate affected by reference rate reform. It is anticipated that this ASU will simplify any modifications that are executed before December 31, 2022 that are directly related to LIBOR transition by allowing prospective recognition of the continuation of the contract, rather than extinguishment of the old contract resulting in writing off unamortized fees/costs. ASU No. 2020-04 was effective upon issuance and generally can be applied through December 31, 2022. The adoption of ASU 2020-04 did not significantly impact the Company’s Consolidated Financial Statements.
