BASIS OF PRESENTATION

BASIS OF PRESENTATION	3 Months Ended
	Mar. 31, 2022
Organization, Consolidation and Presentation of Financial Statements [Abstract]
BASIS OF PRESENTATION	BASIS OF PRESENTATION 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. These interim financial statements have been prepared in accordance with the instructions to Form 10-Q and Article 10 of Regulation S-X, and accordingly, certain information and footnote disclosures normally included in financial statements prepared according to GAAP have been omitted. The results for any interim period are not necessarily indicative of results for the full year. These consolidated financial statements should be read in conjunction with the audited financial statements and disclosures Berkshire Hills Bancorp, Inc. previously filed with the Securities and Exchange Commission in the Company’s Annual Report on Form 10-K for the year ended December 31, 2021. In management’s opinion, all adjustments necessary for a fair statement are reflected in the interim periods. 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 9 – Other Commitments, Contingencies, Off-Balance Sheet Activities, and Pandemic Impact for pandemic related risks and uncertainties. Recently Adopted Accounting Principles There were no new applicable material accounting pronouncements adopted by the Company since December 31, 2021. Future Application of Accounting Pronouncements In March 2022, the FASB issued ASU No. 2022-01, “Derivatives and Hedging (Topic 815): Fair Value Hedging – Portfolio Layer Method.” The guidance expands the current last-of-layer method to allow multiple hedge layers of a single closed portfolio (renamed to portfolio layer method) and expands the portfolio layer method to include nonprepayable financial assets. The ASU specifies eligible hedging instruments in a single-layer hedge and provides additional guidance on accounting for and disclosure of hedge basis adjustments that are applicable to the portfolio layer method. Further, hedge basis adjustments should be considered when determining credit losses for assets included in the closed portfolio. The amendments in this ASU are effective for fiscal years ending after December 15, 2022, and interim periods within those fiscal years. 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. In March 2022, the FASB issued ASU No. 2022-02, “Financial Instruments – Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures.” 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. The amendments in this ASU are effective for fiscal years ending after December 15, 2022, and interim periods within those fiscal years. Early adoption is permitted and the Company can elect to adopt the amendments about TDRs and related disclosure enhancements separately from the amendments related to vintage disclosures. The Company is still evaluating; however, the adoption is not expected to have a material impact on the Company’s Consolidated Financial Statements.

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.

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 March 31, 2022, prior to this recovery. The Company’s ability and intent to hold these securities until recovery is supported by the Company’s strong capital and liquidity positions as well as its historically low portfolio turnover.

Credit Loss [Abstract]
LOANS AND ALLOWANCE FOR CREDIT LOSSES	LOANS AND ALLOWANCE FOR CREDIT LOSSES The following is a summary of total loans by regulatory call report code with sub-segmentation based on underlying collateral for certain loan types: (In thousands) March 31, 2022 December 31, 2021 Construction $ 310,778 $ 324,282 Commercial multifamily 640,922 515,817 Commercial real estate owner occupied 609,526 606,477 Commercial real estate non-owner occupied 2,207,124 2,156,929 Commercial and industrial 1,350,752 1,284,429 Residential real estate 1,665,304 1,489,248 Home equity 244,649 252,366 Consumer other 238,268 196,299 Total loans $ 7,267,323 $ 6,825,847 Allowance for credit losses 99,475 106,094 Net loans $ 7,167,848 $ 6,719,753 As of March 31, 2022 and December 31, 2021, outstanding loans originated under the Small Business Administration ("SBA") Paycheck Protection Program ("PPP") totaled $15.6 million and $29.9 million, respectively. 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. During the three months ended March 31, 2022, there were no loans reclassified to held for sale. During the three months ended March 31, 2021, the Company reclassified $9.5 million of commercial loans to held for sale, reflecting its intent to sell these loans. Held for sale loans are not contained in the balances within this note and are accounted for at the lower of carrying value or fair market value within loans held for sale on the Consolidated Balance Sheet. 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). The Company’s activity in the allowance for credit losses for loans for the three months ended March 31, 2022 and March 31, 2021 was as follows: (In thousands) Balance at Beginning of Period Charge-offs Recoveries Provision for Credit Losses Balance at End of Period Three months ended March 31, 2022 Construction $ 3,206 $ — $ — $ (701) $ 2,505 Commercial multifamily 6,120 — — (349) 5,771 Commercial real estate owner occupied 12,752 (130) 209 (1,333) 11,498 Commercial real estate non-owner occupied 32,106 (4,884) 1,266 (2,674) 25,814 Commercial and industrial 22,584 (653) 1,288 (270) 22,949 Residential real estate 22,406 (164) 388 (4,814) 17,816 Home equity 4,006 — 134 (837) 3,303 Consumer other 2,914 (216) 137 6,984 9,819 Total allowance for credit losses $ 106,094 $ (6,047) $ 3,422 $ (3,994) $ 99,475 (In thousands) Balance at Beginning of Period Charge-offs Recoveries Provision for Credit Losses Balance at End of Period Three months ended March 31, 2021 Construction $ 5,111 $ — $ — $ (714) $ 4,397 Commercial multifamily 5,916 (124) 62 497 6,351 Commercial real estate owner occupied 12,380 (376) 12 2,241 14,257 Commercial real estate non-owner occupied 35,850 (6,658) 126 5,243 34,561 Commercial and industrial 25,013 (3,320) 644 3,734 26,071 Residential real estate 28,491 (377) 437 (2,751) 25,800 Home equity 6,482 (77) 24 (680) 5,749 Consumer other 8,059 (528) 160 (1,077) 6,614 Total allowance for credit losses $ 127,302 $ (11,460) $ 1,465 $ 6,493 $ 123,800 The Company’s allowance for credit losses on unfunded commitments is recognized as a liability (other liability on consolidated balance sheet), with adjustments to the reserve recognized in other noninterest expense in the consolidated statement of income. The Company’s activity in the allowance for credit losses on unfunded commitments for the three months ended March 31, 2022 and March 31, 2021 was as follows: Three Months Ended (In thousands) 2022 2021 Balance at beginning of period $ 7,043 $ 7,629 Expense for credit losses — 200 Balance at end of period $ 7,043 $ 7,829 Credit Quality Information The Company monitors the credit quality of its portfolio by using internal risk ratings that are based on regulatory guidance. 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 annual, 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.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVE FINANCIAL INSTRUMENTS AND HEDGING ACTIVITIES	DERIVATIVE FINANCIAL INSTRUMENTS AND HEDGING ACTIVITIES As of March 31, 2022, the Company held derivatives with a total notional amount of $3.7 billion. The Company had economic hedges totaling $3.7 billion and $1.2 million non-hedging derivatives, which are not designated as hedges for accounting purposes 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 $0.3 billion, and $0.3 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 and Capital 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 March 31, 2022. The Company pledged collateral to derivative counterparties in the form of cash totaling $38.6 million and securities with an amortized cost of $45.4 million and a fair value of $45.3 million as of March 31, 2022. 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.

Economic hedges As of March 31, 2022, the Company has an interest rate swap with a $7.7 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. There was no credit valuation loss adjustment arising from the difference in credit worthiness of the commercial loan and financial institution counterparties as of March 31, 2022. 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 gets paid 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. Changes in fair value are recorded in current period earnings. 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 originated for sale. The forward sale commitments are accounted for as derivatives with changes in fair value recorded in current period earnings. 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 sale 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 sale 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 TBA 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 interest rate lock commitments (“IRLCs”), or 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. IRLCs that relate to the origination of mortgage loans that will be held for sale are considered derivative financial instruments under applicable accounting guidance. Outstanding IRLCs expose the Company to the risk that the price of the mortgage loans underlying the commitments may decline due to increases in mortgage interest rates from inception of the rate lock to the funding of the loan. The IRLCs are free-standing derivatives which are carried at fair value with changes recorded in non-interest income in the Company’s consolidated statements of operations. Changes in the fair value of IRLCs 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. Amounts included in the Consolidated Statements of Income related to economic hedges and non-hedging derivatives were as follows: Three Months Ended March 31, (In thousands) 2022 2021 Economic hedges Interest rate swap on industrial revenue bond: Unrealized gain recognized in other non-interest income $ 432 $ 346 Interest rate swaps on loans with commercial loan customers: Unrealized (loss) recognized in other non-interest income (78,698) (60,302) Favorable change in credit valuation adjustment recognized in other non-interest income 867 2,502 Offsetting interest rate swaps on loans with commercial loan customers: Unrealized gain recognized in other non-interest income 78,698 60,302 Risk participation agreements: Unrealized (loss) recognized in other non-interest income (108) (329) Forward commitments: Unrealized (loss)/gain recognized in other non-interest income (127) 6 Realized gain/(loss) in other non-interest income — (6) Non-hedging derivatives Commitments to lend Unrealized (loss) recognized in other non-interest income $ (106) $ (550) Realized gain in other non-interest income 252 1,352 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 statements of condition. 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 $26.7 million and $2.2 million as of March 31, 2022 and December 31, 2021, respectively. The Company had net asset positions with its commercial banking counterparties totaling $22.7 million and $76.8 million as of March 31, 2022 and December 31, 2021, respectively. The Company had net liability positions with its financial institution counterparties totaling $20.3 million and $33.3 million as of March 31, 2022 and December 31, 2021, respectively. The Company had net liability positions with its commercial banking counterparties totaling $25.3 million as of March 31, 2022. The Company had $2.5 million net liability positions with its commercial banking counterparties as of December 31, 2021. The Company has collateral pledged to cover this liability.

OTHER COMMITMENTS, CONTINGENCIES, OFF-BALANCE SHEET ACTIVITIES, AND PANDEMIC IMPACT	OTHER COMMITMENTS, CONTINGENCIES, OFF-BALANCE SHEET ACTIVITIES, AND PANDEMIC IMPACT In March 2020, the World Health Organization declared a novel strain of coronavirus ("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 continuing 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. 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, deferred tax assets, lease right-of-use assets, or counter-party risk derivatives.

Equity [Abstract]
CAPITAL RATIOS AND SHAREHOLDERS' EQUITY	CAPITAL RATIOS AND SHAREHOLDERS’ EQUITY The actual and required capital ratios were as follows: March 31, December 31, Minimum Capital Requirement Company (consolidated) Total capital to risk-weighted assets 16.0 % 17.3 % 8.0 % Common equity tier 1 capital to risk-weighted assets 13.9 15.0 4.5 Tier 1 capital to risk-weighted assets 14.2 15.3 6.0 Tier 1 capital to average assets 10.3 10.5 4.0 March 31, December 31, Regulatory Minimum to be Adequately Capitalized Regulatory Bank Total capital to risk-weighted assets 14.5 % 15.9 % 8.0 % 10.0 % Common equity tier 1 capital to risk-weighted assets 13.5 14.8 4.5 6.5 Tier 1 capital to risk-weighted assets 13.5 14.8 6.0 8.0 Tier 1 capital to average assets 9.8 10.1 4.0 5.0 The Company and the Bank are subject to regulatory capital requirements administered by federal banking agencies. Capital adequacy guidelines and, additionally for banks, prompt corrective action regulations, involve quantitative measures of assets, liabilities, and certain off-balance sheet items calculated under regulatory accounting practices. Failure to meet capital requirements can initiate regulatory action. At each date shown, the Company met the minimum capital requirements and the Bank met the conditions to be classified as “well capitalized” under the relevant regulatory framework. To be categorized as well capitalized, an institution must maintain minimum total risk-based, Tier 1 risk-based, and Tier 1 leverage ratios as set forth in the table above. Effective January 1, 2015, the Company and the Bank became subject to the Basel III rule that requires the Company and the Bank to assess their Common equity Tier 1 capital to risk weighted assets. The Bank's Common equity Tier 1 capital to risk weighted assets exceeds the minimum to be well capitalized. In addition, the final capital rules added a requirement to maintain a minimum conservation buffer, composed of Common equity Tier 1 capital, of 2.5% of risk-weighted assets, to be phased in over three years and applied to the Common equity Tier 1 risk-based capital ratio, the Tier 1 risk-based capital ratio, and the Total risk-based capital ratio. As of January 1, 2019, banking organizations must maintain a minimum Common equity Tier 1 risk-based capital ratio of 7.0%, a minimum Tier 1 risk-based capital ratio of 8.5%, and a minimum Total risk-based capital ratio of 10.5%. The final capital rules impose restrictions on capital distributions and certain discretionary cash bonus payments if the minimum capital conservation buffer is not met. At March 31, 2022, the capital levels of both the Company and the Bank exceeded all regulatory capital requirements and the Bank's regulatory capital ratios were above the minimum levels required to be considered well capitalized for regulatory purposes. The capital levels of both the Company and the Bank at March 31, 2022 also exceeded the minimum capital requirements including the currently applicable capital conservation buffer of 2.5%.

Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENTS	FAIR VALUE MEASUREMENTS A description of the valuation methodologies used for assets and liabilities measured at fair value, as well as the general classification of such instruments pursuant to the valuation hierarchy, is set forth below. These valuation methodologies were applied to all of the Company’s financial assets and financial liabilities that are carried at fair value. Recurring Fair Value Measurements The following table summarizes financial assets and financial liabilities measured at fair value on a recurring basis as of March 31, 2022 and December 31, 2021, segregated by the level of the valuation inputs within the fair value hierarchy utilized to measure fair value. March 31, 2022 Level 1 Level 2 Level 3 Total (In thousands) Inputs Inputs Inputs Fair Value Trading security $ — $ — $ 7,798 $ 7,798 Securities available for sale: U.S Treasuries — 290,609 — 290,609 Municipal bonds and obligations — 70,223 — 70,223 Agency collateralized mortgage obligations — 697,712 — 697,712 Agency residential mortgage-backed securities — 654,386 — 654,386 Agency commercial mortgage-backed securities — 258,324 — 258,324 Corporate bonds — 40,478 4,020 44,498 Other bonds and obligations — 16,823 — 16,823 Marketable equity securities 14,064 655 — 14,719 Loans held for investment at fair value — — 1,197 1,197 Loans held for sale — 300 — 300 Derivative assets — 49,046 25 49,071 Capitalized servicing rights — — 1,786 1,786 Derivative liabilities — 45,809 — 45,809 December 31, 2021 Level 1 Level 2 Level 3 Total (In thousands) Inputs Inputs Inputs Fair Value Trading security $ — $ — $ 8,354 $ 8,354 Securities available for sale: U.S Treasuries — 59,973 — 59,973 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 — 18,246 — 18,246 Marketable equity securities 14,798 655 — 15,453 Loans held for investment at fair value — — 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 There were no transfers between levels during the three months ended March 31, 2022. 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 fair value of 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 an $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 March 31, 2022. Aggregate Fair Value March 31, 2022 Aggregate Aggregate Less Aggregate (In thousands) Fair Value Unpaid Principal Unpaid Principal Loans held for investment at fair value $ 1,197 $ 23,148 $ (21,951) 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) Loans Held for Sale. The Company elected the fair value option for all loans held for sale (HFS) 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 Fair Value March 31, 2022 Aggregate Aggregate Less Aggregate (In thousands) Fair Value Unpaid Principal Unpaid Principal Loans held for sale $ 300 $ 291 $ 9 Aggregate Fair Value December 31, 2021 Aggregate Aggregate Less Aggregate (In thousands) Fair Value Unpaid Principal Unpaid Principal Loans held for sale $ 6,110 $ 5,926 $ 184 The changes in fair value of loans held for sale for the three months ended March 31, 2022, were losses of $175 thousand. During the three ended March 31, 2022, originations of loans held for sale totaled $7.4 million and sales of loans originated for sale totaled $13.1 million. The changes in fair value of loans held for sale for the three months ended March 31, 2021, were gains of $6 thousand. During the three months ended March 31, 2021, originations of loans held for sale totaled $44.0 million and sales of loans originated for sale totaled $46.9 million. 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 March 31, 2022, the Company assessed the significance of the impact of the credit valuation adjustments on the overall valuation of its derivative positions and determined that the credit valuation adjustments are not significant to the overall valuation of its derivatives. As a result, the Company determined that its derivative valuations in their entirety are classified in Level 2 of the fair value hierarchy. 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 specific interest rate and within a specified period of time. The estimated fair value of commitments to originate residential mortgage loans for sale is based on quoted prices for similar loans in active markets. However, this value is adjusted by a factor which considers the likelihood that the loan in a lock position 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 are classified as Level 3 measurements. Forward Sale Commitments . The Company utilizes forward sale commitments as economic hedges against potential changes in the values of the commitments to lend and loans originated for sale. To Be Announced (“TBA”) mortgage-backed securities forward commitment sales are used as the hedging instrument, 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 commitments are classified as Level 3 measurements. 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 and liabilities that were measured at fair value on a recurring basis for the three months ended March 31, 2022 and 2021.

The following is a summary of applicable non-recurring fair value measurements. There are no liabilities measured at fair value on a non-recurring basis.

There were no Level 1 or Level 2 nonrecurring fair value measurements for the periods ended March 31, 2022 and December 31, 2021. 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 amount does not necessarily represent the fair value of the loan. Real estate collateral is typically valued using appraisals or other indications of value based on recent comparable sales of similar properties or assumptions generally observable in the marketplace. However, the choice of observable data is subject to significant judgment, and there are often adjustments based on judgment in order to make observable data comparable and to consider the impact of time, the condition of properties, interest rates, and other market factors on current values. Additionally, commercial real estate appraisals frequently involve discounting of projected cash flows, which relies inherently on unobservable data. Therefore, nonrecurring fair value measurement adjustments that relate to real estate collateral have generally been classified as Level 3. Estimates of fair value for other collateral that supports commercial loans are generally based on assumptions not observable in the marketplace and therefore such valuations have been classified as Level 3. Capitalized loan servicing rights . A loan servicing right asset represents the amount by which the present value of the estimated future net cash flows to be received from servicing loans exceed adequate compensation for performing the servicing. The fair value of servicing rights is estimated using a present value cash flow model. The most important assumptions used in the valuation model are the anticipated rate of the loan prepayments and discount rates. Adjustments are only recorded when the discounted cash flows derived from the valuation model are less than the carrying value of the asset. Although some assumptions in determining fair value are based on standards used by market participants, some are based on unobservable inputs and therefore are classified in Level 3 of the valuation hierarchy. Summary of Estimated Fair Values of Financial Instruments The following tables summarize the estimated fair values (represents exit price), and related carrying amounts, of the Company’s financial instruments. Certain financial instruments and all non-financial instruments are excluded.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	BASIS OF PRESENTATION 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. These interim financial statements have been prepared in accordance with the instructions to Form 10-Q and Article 10 of Regulation S-X, and accordingly, certain information and footnote disclosures normally included in financial statements prepared according to GAAP have been omitted. The results for any interim period are not necessarily indicative of results for the full year. These consolidated financial statements should be read in conjunction with the audited financial statements and disclosures Berkshire Hills Bancorp, Inc. previously filed with the Securities and Exchange Commission in the Company’s Annual Report on Form 10-K for the year ended December 31, 2021. In management’s opinion, all adjustments necessary for a fair statement are reflected in the interim periods.
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 9 – Other Commitments, Contingencies, Off-Balance Sheet Activities, and Pandemic Impact for pandemic related risks and uncertainties.
Recently Adopted Accounting Principles and Future Application of Accounting Pronouncements	Recently Adopted Accounting Principles There were no new applicable material accounting pronouncements adopted by the Company since December 31, 2021. Future Application of Accounting Pronouncements In March 2022, the FASB issued ASU No. 2022-01, “Derivatives and Hedging (Topic 815): Fair Value Hedging – Portfolio Layer Method.” The guidance expands the current last-of-layer method to allow multiple hedge layers of a single closed portfolio (renamed to portfolio layer method) and expands the portfolio layer method to include nonprepayable financial assets. The ASU specifies eligible hedging instruments in a single-layer hedge and provides additional guidance on accounting for and disclosure of hedge basis adjustments that are applicable to the portfolio layer method. Further, hedge basis adjustments should be considered when determining credit losses for assets included in the closed portfolio. The amendments in this ASU are effective for fiscal years ending after December 15, 2022, and interim periods within those fiscal years. 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. In March 2022, the FASB issued ASU No. 2022-02, “Financial Instruments – Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures.” 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. The amendments in this ASU are effective for fiscal years ending after December 15, 2022, and interim periods within those fiscal years. Early adoption is permitted and the Company can elect to adopt the amendments about TDRs and related disclosure enhancements separately from the amendments related to vintage disclosures. The Company is still evaluating; however, the adoption is not expected to have a material impact on the Company’s Consolidated Financial Statements.
