Accounting Policies [Abstract]
SIGNIFICANT ACCOUNTING POLICIES	SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation and Use of Estimates The accompanying unaudited Condensed Consolidated Financial Statements have been prepared by the Company in U.S. dollars and in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) for interim financial reporting, which do not conform in all respects to the requirements of U.S. GAAP for annual financial statements. Accordingly, these notes to the unaudited Condensed Consolidated Financial Statements should be read in conjunction with the audited Consolidated Financial Statements prepared in accordance with U.S. GAAP that are contained in the Company’s Annual Report on Form 10-K for the year ended December 31, 2024, filed with the U.S. Securities and Exchange Commission (the “SEC”) and the Canadian Securities Administrators (the “CSA”) on February 19, 2025. The unaudited Condensed Consolidated Financial Statements have been prepared using accounting policies that are consistent with the policies used in preparing the Company’s audited Consolidated Financial Statements for the year ended December 31, 2024. The unaudited Condensed Consolidated Financial Statements reflect all normal and recurring adjustments necessary for a fair statement of the Company’s financial position and results of operations for the interim periods. The operating results for the interim periods presented are not necessarily indicative of the results expected for the full year. Separation of the Bausch + Lomb Eye Health Business On August 6, 2020, the Company announced its plan to separate its eye health business, consisting of its Bausch + Lomb global Vision Care, Surgical and Pharmaceuticals businesses into an independent publicly traded entity, Bausch + Lomb, from the remainder of Bausch Health Companies Inc. (the “B+L Separation”). As part of this plan, in May 2022, a wholly owned subsidiary of Bausch Health sold common shares of Bausch + Lomb pursuant to an initial public offering of Bausch + Lomb (the “B+L IPO”). Following the B+L IPO, Bausch Health indirectly holds 310,449,643 common shares of Bausch + Lomb, which represents approximately 88% of B+L’s outstanding common shares as of September 30, 2025. The completion of the full B+L Separation, which may be accomplished by the transfer of all or a portion of the Company’s remaining direct or indirect equity interest in Bausch + Lomb to its shareholders (the “Distribution”), the monetization of all or a portion of the Company’s ownership interest in Bausch + Lomb, or a combination thereof, is subject to the achievement of targeted debt leverage ratios and the receipt of any applicable shareholder and other necessary approvals. The Company continues to evaluate all relevant factors and considerations related to completing the B+L Separation, including the Xifaxan® Generics Litigation (see “Xifaxan® Paragraph IV Proceedings” of Note 18, “LEGAL PROCEEDINGS”). The B+L IPO established two separate companies that include: (i) a diversified pharmaceutical company comprised of the Salix, International, Diversified (neurology, dermatology, generic and dentistry pharmaceutical products) and Solta Medical aesthetic medical device businesses and (ii) a fully integrated eye health company which consists of the Bausch + Lomb Vision Care, Surgical and Pharmaceuticals businesses. These unaudited Condensed Consolidated Financial Statements do not include any adjustments to give effect to the B+L Separation. Use of Estimates In preparing the unaudited Condensed Consolidated Financial Statements, management is required to make estimates and assumptions. The estimates and assumptions used by the Company affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the unaudited Condensed Consolidated Financial Statements, and the reported amounts of revenue and expenses during the reporting periods. Actual results could differ from these estimates and the differences could be material. On an ongoing basis, management reviews its estimates to ensure that these estimates appropriately reflect changes in the Company’s business and new information as it becomes available. If historical experience and other factors used by management to make these estimates do not reasonably reflect future activity, the Company’s results of operations and financial position could be materially impacted. Principles of Consolidation The unaudited Condensed Consolidated Financial Statements include the accounts of the Company and those of its subsidiaries and any variable interest entities for which the Company is the primary beneficiary. All intercompany transactions and balances have been eliminated. Reclassifications Certain reclassifications have been made to prior year amounts to conform to the current year presentation. New Accounting Standards There were no new accounting standards adopted during the nine months ended September 30, 2025. Recently Issued Accounting Standards, Not Adopted as of September 30, 2025 In September 2025, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) 2025-06, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software (“ASU 2025-06”). This ASU removes all references to software development project stages and requires entities to start capitalizing software costs when both of the following occur: (i) management has authorized and committed to funding the software project and (ii) it is probable that the project will be completed and the software will be used to perform the function intended. The amendment in ASU 2025-06 is effective for fiscal years beginning after December 15, 2027, and interim periods within those fiscal years, with early adoption permitted. The amendments can be applied prospectively, retrospectively, or via a modified prospective transition method. The Company is evaluating the impact of adoption on its consolidated financial statements and related disclosures. In July 2025, the FASB issued ASU 2025-05, Financial Instruments - Credit Losses (Topic 326) - Measurement of Credit Losses for Accounts Receivable and Contract Assets (“ASU 2025-05”), which simplifies the estimation of credit losses on current accounts receivable and current contract assets arising from transactions accounted for under Accounting Standards Codification (“ASC”) 606, Revenue from Contracts with Customers, and allows entities to elect a practical expedient to assume that the current conditions as of the balance sheet date will remain unchanged for the remaining life of the asset when developing a reasonable and supportable forecast as part of estimating expected credit losses on these assets. The amendments in ASU 2025-05 are effective for fiscal years beginning after December 15, 2025 and for interim periods within fiscal years beginning after December 15, 2025. The Company is evaluating the impact of adoption on its consolidated financial statements and related disclosures. In November 2024, the FASB issued ASU 2024-03, Income Statement – Reporting Comprehensive Income – Expense Disaggregation (Subtopic 220-40): Disaggregation of Income Statement Expense (“ASU 2024-03”), which requires public companies to disclose, in interim and annual reporting periods, additional information about specific expenses in the financial statements. The amendments in ASU 2024-03 are effective for the Company beginning with its 2027 annual report, and its interim periods beginning in 2028. Early adoption is permitted and is effective on either a prospective basis or retrospective basis. The Company is evaluating the impact of adoption on its consolidated financial statements and related disclosures. In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures (“ASU 2023-09”), which requires disclosures of disaggregated income taxes paid, prescribes standard categories for the components of the effective tax rate reconciliation and modifies certain other income tax-related disclosures. The enhanced income tax related disclosures required by ASU 2023-09 are effective for the Company beginning with its 2025 annual report. The Company is evaluating the impact of adoption on its disclosures.
