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, 2023. In management’s opinion, all adjustments necessary for a fair statement are reflected in the interim periods. Reclassifications Certain items in prior financial statements have been reclassified to conform to the current presentation. Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent liabilities at the date of the financial statements. Actual results could differ from those estimates. Recently Adopted Accounting Principles Effective January 1, 2024, the Company adopted the provisions of Financial Accounting Standards Board (FASB) Accounting Standards Update (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)" (ASU 2023-02). ASU 2023-02 expanded the permitted use of the proportional amortization method (PAM), which was previously only available to low-income housing tax credit investments, to other tax equity investments if certain conditions are met. Under PAM, the initial cost of an investment is amortized in proportion to the income tax benefits received and both the amortization of the investment and the income tax benefits received are recognized as a component of income tax expense. Under this ASU, an entity has the option to apply PAM to applicable investments on a tax-credit-program-by-tax-credit-program basis. The Company has elected PAM for its public welfare investments which consist of Affordable Housing and New Market tax credit investments. In addition, the amendments in this ASU require that all tax equity investments accounted for using PAM use the delayed equity contribution guidance in paragraph ASC 323-740-25-3, requiring a liability be recognized for delayed equity contributions that are unconditional and legally binding or for equity contributions that are contingent upon a future event when that contingent event becomes probable. The amendments in this ASU also require additional disclosures in interim and annual periods concerning investments for which PAM is applied, including (i) the nature of tax equity investments, and (ii) the effect of tax equity investments and related income tax credits and other income tax benefits on the financial position and results of operations. The provisions of this ASU became effective for the Company for interim and annual periods beginning January 1, 2024. Refer to Note 15 – Tax Equity Investments for additional information. The adoption of this ASU did not have a material impact on the Company's consolidated financial statements. Future Application of Accounting Pronouncements 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.
