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. Reclassification 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. 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 and unsecured consumer 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 and unsecured consumer 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 nonaccrual or charged-off is reversed against interest income, except for certain loans designated as well-secured. The interest on nonaccrual 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 on Loans The allowance for credit losses on loans (“ACLL”) is comprised of the allowance for credit losses on loans. 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 uncollectability 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 Company’s allowance for credit losses on unfunded commitments is recognized as a liability (other liability on the Consolidated Balance Sheets), with adjustments to the reserve recognized in other noninterest expense in the Consolidated Statements of Operations. 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 may be more adversely affected by conditions in the real estate markets or in the general 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 and 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 credit losses on loans 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 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 credit losses on loans. 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 Income. 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. 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. On September 1, 2021, the Company completed the sale of substantially all of the assets, and the assumption of certain liabilities, of Berkshire Insurance Group, Inc. (“BIG”) to Brown & Brown of Massachusetts, LLC ("Buyer"), a Massachusetts limited liability company. This sale was made pursuant to the Asset Purchase Agreement dated August 24, 2021. The Buyer paid BIG an aggregate purchase price of $41.5 million, minus $1.6 million for executive goodwill purchase price payments paid by the Buyer at the Closing to certain executives of BIG. The Company recorded a $37.2 million pre-tax gain related to this sale in 2021, which is included in gain on sale of business operations and assets on the Consolidated Statements of Income. 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 14 - 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 consolidated balance sheets 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/(loss), net of tax. Due to the SI Financial acquisition in 2019, the Company inherited a tax-qualified defined benefit pension plan. The plan was frozen effective September 6, 2013. The plan is a single plan under the Internal Revenue Code and, as a result, all of the assets stand behind all of liabilities. Accordingly, contributions made by a participating employer may be used to provide benefits to participants of other participating employers. 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 Effective January 1, 2023, the Company adopted ASU No. 2022-02, “Financial Instruments – Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures.” The adoption did not have a material impact on the Company’s Consolidated Financial Statements. The ASU eliminates the troubled debt restructuring (“TDR”) accounting model that was adopted with Topic 326, “Financial Instruments – Credit Losses” and enhances disclosure requirements for certain loan refinancings and restructurings when a borrower is experiencing financial difficulty. The ASU requires prospective disclosure of current-period gross write-offs by year of origination. Refer to Note 5 – Loans and Related Allowance for Credit Losses for the new financial statement disclosures applicable under this update. Future Application of Accounting Pronouncements In March 2023, the FASB issued ASU No. 2023-02, “Investments – Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method (a consensus of the Emerging Issues Task Force).” The guidance is intended to improve the accounting and disclosures for investments in tax credit structures. The ASU allows entities to elect to account for qualifying tax equity investments using the proportional amortization method, regardless of the program giving rise to the related income tax credits. Previously, this method was only available for qualifying investments in low-income housing tax credit structures. The amendments in this ASU are effective for fiscal years beginning after December 15, 2023, and interim periods within those fiscal years. Early adoption is permitted. The Company is still evaluating; however, the adoption removes amortization expense from non-interest income and moves to tax expense resulting in an increase to the effective tax rate. In December 2023, the FASB issued ASU No. 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures.” The ASU requires disclosure in the rate reconciliation table of additional categories of information and more details about the reconciling items in some categories if items meet a quantitative threshold. The ASU also requires all entities to disclose income taxes paid, net of refunds, disaggregated by federal, state and foreign taxes for annual periods and to disaggregate the information by jurisdiction based on a quantitative threshold, among other things. The amendments in this ASU are effective for annual periods beginning after December 15, 2024. Early adoption is permitted. The Company is still evaluating; however, the adoption is not expected to have a material impact on the Company’s Consolidated Financial Statements.

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.

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.

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.

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 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 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 and unsecured consumer 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 and unsecured consumer 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 nonaccrual or charged-off is reversed against interest income, except for certain loans designated as well-secured. The interest on nonaccrual 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.

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.

The allowance for credit losses on loans (“ACLL”) is comprised of the allowance for credit losses on loans. 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 uncollectability 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 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 Company’s allowance for credit losses on unfunded commitments is recognized as a liability (other liability on the Consolidated Balance Sheets), with adjustments to the reserve recognized in other noninterest expense in the Consolidated Statements of Operations.

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 may be more adversely affected by conditions in the real estate markets or in the general 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.

Loans that do not share risk characteristics are evaluated on an individual basis and 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 credit losses on loans in lieu of an allocation of a specific allowance amount when such an amount has been identified definitively as uncollectible.

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.

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 credit losses on loans. 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 Income. 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.

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.

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.

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 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.

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.

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

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.

On September 1, 2021, the Company completed the sale of substantially all of the assets, and the assumption of certain liabilities, of Berkshire Insurance Group, Inc. (“BIG”) to Brown & Brown of Massachusetts, LLC ("Buyer"), a Massachusetts limited liability company. This sale was made pursuant to the Asset Purchase Agreement dated August 24, 2021. The Buyer paid BIG an aggregate purchase price of $41.5 million, minus $1.6 million for executive goodwill purchase price payments paid by the Buyer at the Closing to certain executives of BIG. The Company recorded a $37.2 million pre-tax gain related to this sale in 2021, which is included in gain on sale of business operations and assets on the Consolidated Statements of Income.

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.

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.

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.”

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 14 - Derivative Instruments and Hedging Activities to the financial statements for more information on commitments to lend and forward commitments.

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.

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 consolidated balance sheets 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/(loss), net of tax.

Due to the SI Financial acquisition in 2019, the Company inherited a tax-qualified defined benefit pension plan. The plan was frozen effective September 6, 2013. The plan is a single plan under the Internal Revenue Code and, as a result, all of the assets stand behind all of liabilities. Accordingly, contributions made by a participating employer may be used to provide benefits to participants of other participating employers.

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.

The ASU eliminates the troubled debt restructuring (“TDR”) accounting model that was adopted with Topic 326, “Financial Instruments – Credit Losses” and enhances disclosure requirements for certain loan refinancings and restructurings when a borrower is experiencing financial difficulty. The ASU requires prospective disclosure of current-period gross write-offs by year of origination. Refer to Note 5 – Loans and Related Allowance for Credit Losses for the new financial statement disclosures applicable under this update.

In March 2023, the FASB issued ASU No. 2023-02, “Investments – Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method (a consensus of the Emerging Issues Task Force).” The guidance is intended to improve the accounting and disclosures for investments in tax credit structures. The ASU allows entities to elect to account for qualifying tax equity investments using the proportional amortization method, regardless of the program giving rise to the related income tax credits. Previously, this method was only available for qualifying investments in low-income housing tax credit structures. The amendments in this ASU are effective for fiscal years beginning after December 15, 2023, and interim periods within those fiscal years. Early adoption is permitted. The Company is still evaluating; however, the adoption removes amortization expense from non-interest income and moves to tax expense resulting in an increase to the effective tax rate.

In December 2023, the FASB issued ASU No. 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures.” The ASU requires disclosure in the rate reconciliation table of additional categories of information and more details about the reconciling items in some categories if items meet a quantitative threshold. The ASU also requires all entities to disclose income taxes paid, net of refunds, disaggregated by federal, state and foreign taxes for annual periods and to disaggregate the information by jurisdiction based on a quantitative threshold, among other things. The amendments in this ASU are effective for annual periods beginning after December 15, 2024. Early adoption is permitted. The Company is still evaluating; however, the adoption is not expected to have a material impact on the Company’s Consolidated Financial Statements.
