Accounting Policies [Abstract]
SIGNIFICANT ACCOUNTING POLICIES	SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation and Use of Estimates The accompanying unaudited 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 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, 2019 , filed with the U.S. Securities and Exchange Commission (the “SEC”) and the Canadian Securities Administrators on February 19, 2020 . The unaudited 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, 2019 , except for the new accounting guidance adopted during the period. The unaudited 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. The unprecedented nature of the COVID-19 pandemic has adversely impacted the global economy. The COVID-19 pandemic and the rapidly evolving reaction of governments, private sector participants and the public in an effort to contain the spread of COVID-19 and/or address its impacts have intensified and have had significant direct and indirect effects on businesses and commerce generally, including disruption to supply chains, employee base and transactional activity, facilities closures and production suspensions, and significantly increased demand for certain goods and services, such as certain pandemic-related medical services and supplies, alongside decreased demand for others, such as elective surgery, retail, hospitality and travel. The extent to which these events may impact the Company's business, financial condition, cash flows and results of operations, in particular, will depend on future developments which are highly uncertain and many of which are outside the Company's control. Such developments include the ultimate geographic spread and duration of the pandemic, new information which may emerge concerning the severity of the COVID-19 virus, the effectiveness and intensity of measures to contain the COVID-19 virus and/or address its impacts, and the economic impact of the pandemic and the reactions to it. Such developments, among others, depending on their nature, duration and intensity, could have a significant adverse effect on the Company's business, financial condition, cash flows and results of operations. To date, the Company has been able to continue its operations with limited disruptions in supply and manufacturing. Although, it is difficult to predict the broad macroeconomic effects that the COVID-19 virus will have on industries or individual companies, the Company has assessed the possible effects and outcomes of the pandemic on, among other things, its supply chain, customers and distributors, discounts and rebates, employee base, product sustainability, research and development efforts, product pipeline and consumer demand and currently believes that its estimates are reasonable. In preparing the unaudited Consolidated Financial Statements, management is required to make estimates and assumptions. This includes estimates and assumptions regarding the nature, timing and extent of the impacts that the COVID-19 pandemic will have on its operations and cash flows. 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 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 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. Adoption of New Accounting Guidance In June 2016, the Financial Accounting Standards Board (“FASB”) issued guidance on the impairment of financial instruments requiring an impairment model based on expected losses rather than incurred losses. Under this guidance, an entity recognizes as an allowance its estimate of expected credit losses. The guidance was effective for the Company beginning January 1, 2020 and was applied using a modified retrospective approach through a cumulative-effect adjustment to accumulated deficit, which resulted in an increase to accumulated deficit of less than $1 million . The application of this guidance did not have a material effect on the Company's results of operations and cash flows. The Company estimates the current expected credit loss on its receivables based on various factors, including historical credit loss experience, customer credit worthiness, value of collaterals (if any), and any relevant current and reasonably supportable future economic factors. Additionally, the Company generally estimates the expected credit loss on a pool basis when customers are deemed to have similar risk characteristics. In August 2018, the FASB issued guidance modifying the disclosure requirements for fair value measurement. The guidance was effective for the Company beginning January 1, 2020. The application of this guidance did not have a material effect on the Company's disclosures. In March 2020, the FASB issued guidance providing optional expedients and exceptions for applying U.S. GAAP to contracts, hedging relationships, and other transactions that reference LIBOR or a reference rate that is expected to be discontinued as a result of reference rate reform. Optional expedients are provided for contract modification accounting within the areas of receivables, debt, leases, derivatives and hedging. The optional amendments are effective for all entities as of March 12, 2020, through December 31, 2022. During the three months ended March 31, 2020 , the Company has not entered into any contract modifications in which the optional expedients were applied. However, if prior to December 31, 2022 the Company enters into a contract modification in which the optional expedients are applied, the Company will evaluate the impact of adoption of this guidance on its financial position, results of operations and cash flows. Recently Issued Accounting Standards, Not Adopted as of March 31, 2020 In August 2018, the FASB issued guidance modifying the disclosure requirements for employers that sponsor defined benefit pension or other postretirement plans. The guidance is effective for annual periods ending after December 15, 2020, with early adoption permitted. The Company is evaluating the impact of adoption of this guidance on its disclosures. In December 2019, the FASB issued guidance simplifying the accounting for income taxes. The guidance is effective for annual periods ending after December 15, 2020, with early adoption permitted. The Company is evaluating the impact of adoption of this guidance on the Company's financial position, results of operations and cash flows.

REVENUE RECOGNITION

REVENUE RECOGNITION	3 Months Ended
	Mar. 31, 2020
Revenue from Contract with Customer [Abstract]
REVENUE RECOGNITION	REVENUE RECOGNITION The Company’s revenues are primarily generated from product sales, principally in the therapeutic areas of eye-health, GI and dermatology, that consist of: (i) branded pharmaceuticals, (ii) generic and branded generic pharmaceuticals, (iii) OTC products and (iv) medical devices (contact lenses, intraocular lenses, ophthalmic surgical equipment and aesthetics devices). Other revenues include alliance and service revenue from the licensing and co-promotion of products and contract service revenue primarily in the areas of dermatology and topical medication. Contract service revenue is derived primarily from contract manufacturing for third parties and is not material. See Note 19, "SEGMENT INFORMATION" for the disaggregation of revenue which depicts how the nature, amount, timing and uncertainty of revenue and cash flows are affected by the economic factors of each category of customer contracts. Product Sales Provisions As is customary in the pharmaceutical industry, gross product sales are subject to a variety of deductions in arriving at reported net product sales. The transaction price for product sales is typically adjusted for variable consideration, which may be in the form of cash discounts, allowances, returns, rebates, chargebacks and distribution fees paid to customers. Provisions for variable consideration are established to reflect the Company’s best estimates of the amount of consideration to which it is entitled based on the terms of the contract. The amount of variable consideration included in the transaction price may be constrained, and is included in the net sales price only to the extent that it is probable that a significant reversal in the amount of the cumulative revenue recognized will not occur in a future period. Provisions for these deductions are recorded concurrently with the recognition of gross product sales revenue and include cash discounts and allowances, chargebacks, and distribution fees, which are paid to direct customers, as well as rebates and returns, which can be paid to direct and indirect customers. Returns provision balances and volume discounts to direct customers are included in Accrued and other current liabilities. All other provisions related to direct customers are included in Trade receivables, net, while provision balances related to indirect customers are included in Accrued and other current liabilities. The Company continually monitors its variable consideration provisions and evaluates the estimates used as additional information becomes available. Adjustments will be made to these provisions periodically to reflect new facts and circumstances that may indicate that historical experience may not be indicative of current and/or future results. The Company is required to make subjective judgments based primarily on its evaluation of current market conditions and trade inventory levels related to the Company's products. This evaluation may result in an increase or decrease in the experience rate that is applied to current and future sales, or an adjustment related to past sales, or both. If the actual amounts paid vary from the Company’s estimates, the Company adjusts these estimates, which would affect net product revenue and earnings in the period such variance becomes known. The following tables present the activity and ending balances of the Company’s variable consideration provisions for the three months ended March 31, 2020 and 2019 .

There were no price appreciation credits for the three months ended March 31, 2019 . Contract Assets and Contract Liabilities There are no contract assets for any period presented. Contract liabilities consist of deferred revenue, the balance of which is not material to any period presented. Allowance for Credit Losses An allowance is maintained for potential credit losses. The Company estimates the current expected credit loss on its receivables based on various factors, including historical credit loss experience, customer credit worthiness, value of collaterals (if any), and any relevant current and reasonably supportable future economic factors. Additionally, the Company generally estimates the expected credit loss on a pool basis when customers are deemed to have similar risk characteristics. Trade receivable balances are written off against the allowance when it is deemed probable that the trade receivable will not be collected. Trade receivables, net are stated net of certain sales provisions and the allowance for credit losses. Allowances for credit losses were $48 million and $48 million as of March 31, 2020 and December 31, 2019, respectively. The activity in the allowance for credit losses for trade receivables for the three months ended March 31, 2020 is as follows. Write-offs charged against the allowance for credit losses and recoveries of amounts previously written off were not material.

Business Combinations [Abstract]
ACQUISITION, LICENSING AGREEMENTS AND ASSETS HELD FOR SALE	ACQUISITION, LICENSING AGREEMENTS AND ASSETS HELD FOR SALE Acquisition of Certain Assets of Synergy Pharmaceuticals Inc. On March 6, 2019, the Company acquired certain assets of Synergy Pharmaceuticals Inc. ("Synergy") for a cash purchase price of approximately $180 million and the assumption of certain liabilities, pursuant to the terms approved by the U.S. Bankruptcy Court for the Southern District of New York on March 1, 2019. Among the assets acquired were the worldwide rights to the Trulance ® (plecanatide) product, a once-daily tablet for adults with chronic idiopathic constipation and irritable bowel syndrome with constipation. This acquired business is included in the Company's Salix segment and is expected to result in additional revenues and costs savings associated with business synergies. Assets Acquired and Liabilities Assumed The acquisition of certain assets of Synergy has been accounted for as a business combination under the acquisition method of accounting as: (i) substantially all the fair value of the assets acquired is not concentrated in a single identifiable asset or group of similar identifiable assets and (ii) substantive inputs and processes were acquired to contribute to the creation of outputs. The following table summarizes the fair values of the assets acquired and liabilities assumed related to the acquisition of certain assets of Synergy as of the acquisition date: (in millions) Accounts receivable $ 7 Inventories 24 Prepaid expenses and other current assets 5 Product brand intangible assets (estimated useful life - 7 years) 159 Accounts payable (1 ) Accrued expenses (17 ) Total identifiable net assets 177 Goodwill 3 Total fair value of consideration transferred $ 180 Goodwill associated with the acquisition of certain assets of Synergy is not deductible for income tax purposes. Revenue and Operating Results Revenues associated with the acquired assets of Synergy during the period March 6, 2019 through December 31, 2019 were $55 million . Operating results associated with the acquired assets of Synergy during the period March 6, 2019 through December 31, 2019 and pro-forma revenues and operating results for the three months ended March 31, 2019 and the year 2019 were not material. Included in Other expense (income), net during the three months ended March 31, 2019 are acquisition-related costs of $8 million directly related to the acquisition of certain assets of Synergy, which include expenditures for advisory, legal, valuation, accounting and other similar services. Licensing Agreements In the normal course of business, the Company may enter into select licensing and collaborative agreements for the commercialization and/or development of unique products. These products are sometimes investigational treatments in early stage development that target unique conditions. The ultimate outcome, including whether the product will be (i) fully developed, (ii) approved by regulatory agencies, (iii) covered by third-party payors or (iv) profitable for distribution, cannot be fairly predicted. The commitment periods under these agreements vary and include customary termination provisions. Expenses arising from commitments, if any, to fund the development and testing of these products and their promotion are recognized as incurred. Royalties due are recognized when earned and milestone payments are accrued when each milestone has been achieved and payment is probable and can be reasonably estimated. Assets Held for Sale In 2019, the Company identified certain products in the Bausch + Lomb/International segment and one product in the Diversified Products segment for disposal. The products and the related assets and liabilities of this disposal group qualified as a business. Revenues associated with this business were $14 million and $19 million for the years 2019 and 2018, respectively. The carrying value of the business, including inventories, intangible assets, goodwill and deferred income taxes, was adjusted to its estimated fair value less costs to sell and reclassified as held for sale as of September 30, 2019 and an impairment of $8 million associated with this business was recognized during the three months ended September 30, 2019. As a result of changing business dynamics, during the three months ended March 31, 2020 , the Company decided not to sell these assets and reclassified $39 million of held for sale assets as assets held and used at their respective fair values at the date of the decision not to sell. This reclassification did not impact the Consolidated Statement of Operations for the three months ended March 31, 2020 .

Restructuring and Related Activities [Abstract]
RESTRUCTURING AND INTEGRATION COSTS	RESTRUCTURING AND INTEGRATION COSTS The Company evaluates opportunities to improve its operating results and implements cost savings programs to streamline its operations and eliminate redundant processes and expenses. The expenses associated with the implementation of these cost savings programs include expenses associated with: (i) reducing headcount, (ii) eliminating real estate costs associated with unused or under utilized facilities and (iii) implementing contribution margin improvement and other cost reduction initiatives.

FAIR VALUE MEASUREMENTS AND FIN

FAIR VALUE MEASUREMENTS AND FINANCIAL INSTRUMENTS	3 Months Ended

Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENTS AND FINANCIAL INSTRUMENTS	FAIR VALUE MEASUREMENTS AND FINANCIAL INSTRUMENTS Fair value measurements are estimated based on valuation techniques and inputs categorized as follows: • Level 1 — Quoted prices in active markets for identical assets or liabilities; • Level 2 — Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities; and • Level 3 — Unobservable inputs that are supported by little or no market activity and that are financial instruments whose values are determined using discounted cash flow methodologies, pricing models, or similar techniques, as well as instruments for which the determination of fair value requires significant judgment or estimation. If the inputs used to measure the financial assets and liabilities fall within more than one level described above, the categorization is based on the lowest level input that is significant to the fair value measurement of the instrument. Assets and Liabilities Measured at Fair Value on a Recurring Basis The following fair value hierarchy table presents the components and classification of the Company’s financial assets and liabilities measured at fair value on a recurring basis: March 31, 2020 December 31, 2019 (in millions) Carrying Value Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Carrying Value Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Assets: Cash equivalents $ 37 $ 12 $ 25 $ — $ 2,696 $ 2,646 $ 50 $ — Restricted cash $ 1,011 $ 1,011 $ — $ — $ 1 $ 1 $ — $ — Cross-currency swaps $ 55 $ — $ 55 $ — $ — $ — $ — $ — Foreign currency exchange contracts $ 1 $ — $ 1 $ — $ — $ — $ — $ — Liabilities: Acquisition-related contingent consideration $ 312 $ — $ — $ 312 $ 316 $ — $ — $ 316 Cross-currency swaps $ — $ — $ — $ — $ 13 $ — $ 13 $ — Foreign currency exchange contracts $ 6 $ — $ 6 $ — $ — $ — $ — $ — Cash equivalents consist of highly liquid investments, primarily money market funds, with maturities of three months or less when purchased, and are reflected in the Consolidated Balance Sheets at carrying value, which approximates fair value due to their short-term nature. As of March 31, 2020 , Restricted cash includes $1,010 million of payments into an escrow fund under the terms of a settlement agreement regarding certain U.S. securities litigation, subject to final court approval, and is reflected in the Consolidated Balance Sheets at carrying value, which approximates fair value due to its short-term nature. These payments will remain in escrow until final approval of the settlement as discussed in Note 18, "LEGAL PROCEEDINGS" . There were no transfers into or out of Level 3 during the three months ended March 31, 2020 . Cross-currency Swaps During the three months ended September 30, 2019, the Company entered into cross-currency swaps, with aggregate notional amounts of $1,250 million , to mitigate fluctuation in the value of a portion of its euro-denominated net investment in its consolidated financial statements from adverse movements in exchange rates. The euro-denominated net investment being hedged is the Company’s investment in certain euro-denominated subsidiaries. The Company had no derivative instruments during the three months ended March 31, 2019 . The Company’s cross-currency swaps qualify for and have been designated as an accounting hedge of the foreign currency exposure of a net investment in a foreign operation and are remeasured at each reporting date to reflect changes in their fair values. The fair value is determined via a mark-to-market analysis, using observable (Level 2) inputs. These inputs may include: (i) the foreign currency exchange spot rate between the euro and U.S. dollar, (ii) the risk-free interest rate and (iii) the credit risk rating for each applicable counterparty. The net change in fair value of cross-currency swaps, is reported as a gain or loss in the Consolidated Statements of Comprehensive Loss as part of Foreign currency translation adjustment to the extent they are effective and remain in Accumulative Comprehensive Income until either the sale or complete, or substantially complete, liquidation of the subsidiary. No portion of the cross-currency swaps were ineffective for the three months ended March 31, 2020 . The Company uses the spot method of assessing hedge effectiveness. The Company has elected to amortize amounts excluded from the assessment of effectiveness over the term of its cross-currency swaps as Interest expense in the Consolidated Statements of Operations. The fair value of the Company’s cross-currency swaps asset as of March 31, 2020 was $55 million . Included in Other non-current assets are $52 million of cross-currency swaps and included in Prepaid expenses and other current assets is $3 million of earned interest within the Consolidated Balance Sheets. The following table presents the effect of hedging instruments on the Consolidated Statements of Comprehensive Loss and the Consolidated Statements of Operations for the three months ended March 31, 2020 : (in millions) Gain recognized in Other Comprehensive Loss Gain excluded from assessment of hedge effectiveness Location of gain in income of excluded component Cross-currency swaps $ 73 $ 6 Interest expense Settlement of the Company's cross-currency swaps occur in February and August each year. During the three months ended March 31, 2020 , the Company received $11 million in settlements which are reported as investing activities in the Consolidated Statements of Cash Flows. Foreign Currency Exchange Contracts During the three months ended March 31, 2020 , the Company entered into foreign currency exchange contracts, with an aggregate notional amount of $163 million . The Company had no foreign currency exchange contracts during 2019. The Company's foreign currency exchange contracts are remeasured at each reporting date to reflect changes in their fair values determined using forward rates, which are observable market inputs, multiplied by the notional amount. The Company's foreign currency exchange contracts are economically hedging the foreign exchange exposure on certain of the Company’s intercompany balances. These contracts have not been designated as an accounting hedge, and therefore the net change in their fair value is reported as a gain or loss in the Consolidated Statements of Operations as part of Foreign exchange and other . The fair value of the Company's foreign currency exchange contracts as of March 31, 2020 was $5 million . Included in Accrued and other current liabilities are $6 million and included in Prepaid expenses and other current assets are $1 million of foreign currency exchange contracts within the Consolidated Balance Sheets. During the three months ended March 31, 2020 , the net change in fair value was a loss of $5 million . Settlements of the Company's foreign currency exchange contracts are reported as operating activities in the Consolidated Statements of Cash Flows. Acquisition-related Contingent Consideration Obligations The fair value measurement of contingent consideration obligations arising from business combinations is determined via a probability-weighted discounted cash flow analysis, using unobservable (Level 3) inputs. These inputs may include: (i) the estimated amount and timing of projected cash flows, (ii) the probability of the achievement of the factor(s) on which the contingency is based and (iii) the risk-adjusted discount rate used to present value the probability-weighted cash flows. Significant increases or decreases in any of those inputs in isolation could result in a significantly higher or lower fair value measurement. At March 31, 2020 , the fair value measurements of acquisition-related contingent consideration were determined using risk-adjusted discount rates ranging from 5% to 25% , and a weighted average risk-adjusted discount rate of 7% . The weighted average risk-adjusted discount rate was calculated by weighting each contract's relative fair value at March 31, 2020. The following table presents a reconciliation of contingent consideration obligations measured on a recurring basis using significant unobservable inputs (Level 3) for the three months ended March 31, 2020 and 2019 : (in millions) 2020 2019 Balance, beginning of period $ 316 $ 339 Adjustments to Acquisition-related contingent consideration: Accretion for the time value of money $ 6 $ 6 Fair value adjustments due to changes in estimates of other future payments 7 (27 ) Acquisition-related contingent consideration 13 (21 ) Payments (17 ) (9 ) Balance, end of period 312 309 Current portion included in Accrued and other current liabilities 44 45 Non-current portion $ 268 $ 264 Assets and Liabilities Measured at Fair Value on a Non-Recurring Basis The following table presents the components and classification of the Company’s financial assets and liabilities measured at fair value on a non-recurring basis: March 31, 2020 December 31, 2019 (in millions) Carrying Value Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Carrying Value Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Other non-current assets: Non-current assets held for sale $ — $ — $ — $ — $ 39 $ — $ — $ 39 Non-current assets held for sale of $39 million included in the Consolidated Balance Sheets as of December 31, 2019 were remeasured to their estimated fair values less costs to sell determined using a discounted cash flow analysis which utilized Level 3 unobservable inputs. As discussed in Note 4, "ACQUISITION, LICENSING AGREEMENTS AND ASSETS HELD FOR SALE" , due to changing business dynamics, the Company decided not to sell these assets during the three months ended March 31, 2020 . Fair Value of Long-term Debt The fair value of long-term debt as of March 31, 2020 and December 31, 2019 was $24,462 million and $27,520 million , respectively, and was estimated using the quoted market prices for the same or similar debt issuances (Level 2) .

INTANGIBLE ASSETS AND GOODWILL	INTANGIBLE ASSETS AND GOODWILL Intangible Assets The major components of intangible assets consist of: March 31, 2020 December 31, 2019 (in millions) Gross Carrying Amount Accumulated Amortization and Impairments Net Carrying Amount Gross Carrying Amount Accumulated Amortization and Impairments Net Carrying Amount Finite-lived intangible assets: Product brands $ 20,989 $ (13,924 ) $ 7,065 $ 21,011 $ (13,544 ) $ 7,467 Corporate brands 914 (348 ) 566 930 (338 ) 592 Product rights/patents 3,284 (2,918 ) 366 3,297 (2,887 ) 410 Partner relationships 155 (154 ) 1 166 (165 ) 1 Technology and other 203 (186 ) 17 209 (189 ) 20 Total finite-lived intangible assets 25,545 (17,530 ) 8,015 25,613 (17,123 ) 8,490 Acquired IPR&D not in service 13 — 13 13 — 13 Bausch + Lomb Trademark 1,698 — 1,698 1,698 — 1,698 $ 27,256 $ (17,530 ) $ 9,726 $ 27,324 $ (17,123 ) $ 10,201 Long-lived assets with finite lives are tested for impairment whenever events or changes in circumstances indicate that the carrying value of an asset may not be recoverable. Impairment charges associated with these assets are included in Asset impairments in the Consolidated Statement of Operations. The Company continues to monitor the recoverability of its finite-lived intangible assets and tests the intangible assets for impairment if indicators of impairment are present. Asset impairments for the three months ended March 31, 2020 were $14 million due to decreases in forecasted sales of a certain product line. Asset impairments for the three months ended March 31, 2019 were $3 million due to the discontinuance of a specific product line not aligned with the focus of the Company's core businesses. Estimated amortization expense of finite-lived intangible assets for the remainder of 2020 and each of the five succeeding years ending December 31 and thereafter is as follows: (in millions) Remainder of 2020 2021 2022 2023 2024 2025 Thereafter Total Amortization $ 1,188 $ 1,374 $ 1,217 $ 1,071 $ 942 $ 832 $ 1,391 $ 8,015 Goodwill The changes in the carrying amounts of goodwill during the three months ended March 31, 2020 and the year ended December 31, 2019 were as follows: (in millions) Bausch + Lomb/ International Salix Ortho Dermatologics Diversified Products Total Balance, January 1, 2019 $ 5,805 $ 3,156 $ 1,267 $ 2,914 $ 13,142 Acquisition of certain assets of Synergy — 3 — — 3 Goodwill reclassified to assets held for sale (Note 4) (18 ) — — — (18 ) Foreign exchange and other (1 ) — — — (1 ) Balance, December 31, 2019 5,786 3,159 1,267 2,914 13,126 Assets held for sale reclassified to goodwill (Note 4) 18 — — — 18 Foreign exchange and other (110 ) — — — (110 ) Balance, March 31, 2020 $ 5,694 $ 3,159 $ 1,267 $ 2,914 $ 13,034 Goodwill is not amortized but is tested for impairment at least annually at the reporting unit level. A reporting unit is the same as, or one level below, an operating segment. The fair value of a reporting unit refers to the price that would be received to sell the unit as a whole in an orderly transaction between market participants. The Company estimates the fair values of all reporting units using a discounted cash flow model which utilizes Level 3 unobservable inputs. The discounted cash flow model relies on assumptions regarding revenue growth rates, gross profit, projected working capital needs, selling, general and administrative expenses, research and development expenses, capital expenditures, income tax rates, discount rates and terminal growth rates. To estimate fair value, the Company discounts the forecasted cash flows of each reporting unit. The discount rate the Company uses represents the estimated weighted average cost of capital, which reflects the overall level of inherent risk involved in its reporting unit operations and the rate of return a market participant would expect to earn. The Company performed its annual impairment test as of October 1, 2019 by first assessing qualitative factors to determine whether it is more likely than not that the fair value of each reporting unit is less than its carrying amount (Step 0). Where the qualitative assessment suggested that it was more likely than not that the fair value of a reporting unit was less than its carrying amount, a quantitative fair value test was performed for that reporting unit (Step 1). The quantitative fair value test was performed utilizing long-term growth rates and discount rates applied to the estimated cash flows in estimation of fair value. To estimate cash flows beyond the final year of its model, the Company estimates a terminal value by applying an in-perpetuity growth assumption and discount factor to determine the reporting unit's terminal value. The Company forecasts cash flows for each reporting unit and takes into consideration economic conditions and trends, estimated future operating results, management's and a market participant's view of growth rates and product lives, and anticipates future economic conditions. Revenue growth rates inherent in these forecasts were based on input from internal and external market research that compare factors such as growth in global economies, recent industry trends and product life-cycles. Macroeconomic factors such as changes in economies, changes in the competitive landscape including the unexpected loss of exclusivity to the Company's product portfolio, changes in government legislation, product life-cycles, industry consolidations and other changes beyond the Company’s control could have a positive or negative impact on achieving its targets. Accordingly, if market conditions deteriorate, or if the Company is unable to execute its strategies, it may be necessary to record impairment charges in the future. 2019 Goodwill Impairment Testing During the interim periods of 2019, no events occurred, or circumstances changed that would indicate that the fair value of any reporting unit might be below its carrying value and therefore, no impairments were recorded. The Company conducted its annual goodwill impairment test as of October 1, 2019 by first assessing qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. Where the qualitative assessment suggested that it was more likely than not that the fair value of a reporting unit was less than its carrying amount, a quantitative fair value test was performed for that reporting unit. In each quantitative fair value test performed, the fair value was greater than the carrying value of the reporting unit. As a result, there was no impairment to the goodwill of any reporting unit. If market conditions deteriorate, or if the Company is unable to execute its strategies, it may be necessary to record impairment charges in the future. Specifically, the Company continues to assess the performance of the Ortho Dermatologics reporting unit and the Neurology and Other reporting unit as compared to their respective projections and will perform qualitative interim assessments of the carrying value and fair value on a quarterly basis to determine if impairment testing of goodwill will be warranted. The Company performed quantitative fair value tests for the Ortho Dermatologics reporting unit and the Neuro and Other reporting unit as of October 1, 2019, utilizing long-term growth rates of 2.0% and 1.5% , and discount rates of 9.8% and 9.0% , respectively, in estimation of the fair value of these reporting units. 2020 Interim Goodwill Impairment Assessment The unprecedented nature of the COVID-19 pandemic has adversely impacted the global economy. As the global economic landscape changes, there is a wide range of possible outcomes regarding the nature and timing of events and reactions to the COVID-19 pandemic, each of which are highly dependent on variables that are difficult to predict at this time. In response to the COVID-19 pandemic, the Company has taken actions to protect its employees, customers and other stakeholders and mitigate the negative impact of the COVID-19 pandemic on its operations and operating results. These and additional actions can increase the costs of doing business during the pandemic and in the periods that follow, including the costs of idling and reopening certain facilities in affected areas. Further, precautionary measures taken by customers, health care patients and consumers in response to the pandemic are expected to impact the timing and amount of revenues during the COVID-19 pandemic. Although the Company's reported revenues for the three months ended March 31, 2020 are less than forecasted and additional pandemic-related declines in revenues are expected in the second quarter and possibly the remainder of 2020, there is currently no indication that these trends are materially other than COVID-19 related. The negative impacts of the COVID-19 pandemic on the global economy were not existing conditions as of October 1, 2019 (the date goodwill was last tested for impairment) and have led to significant volatility in the global equity markets. The Company has been able to continue its operations with limited disruptions and has assessed the potential impact that the COVID-19 pandemic is likely to have on its forecasted cash flows. In performing its assessment, the Company considered the possible affects and outcomes of the COVID-19 pandemic on, among other things, its supply chain, customers and distributors, employee base, product sustainability, research and development activities, product pipeline and consumer demand and related rebates and discounts and has made adjustments, although not considered to be material, to its long-term forecasts as of October 1, 2019 (the date goodwill was last tested for impairment) for these and other matters. After completing this assessment, although not completely insulated from the negative effects of the COVID-19 pandemic, the Company believes that its long-term forecasted cash flows, as adjusted for the possible outcome of the COVID-19 pandemic and other matters, do not indicate that the fair value of any reporting unit may be below its carrying value. During the pandemic, the public has been advised to: (i) remain at home, (ii) limit social interaction, (iii) close non-essential businesses and (iv) postpone certain surgical and elective medical procedures in order to prioritize/conserve available health care resources. During the three months ended March 31, 2020, this has negatively impacted, most notably, the revenues of the Company's Global Vision Care and Global Surgical businesses particularly in Asia where the COVID-19 pandemic originated. The Company anticipates further revenue declines in these businesses during 2020 as it experienced steeper declines in these business revenues in the month of March. Beginning in the second quarter, the Company started experiencing and is anticipating COVID-19 pandemic-related revenue declines in intraocular lenses, medical devices, surgical systems and certain pre- and post-operative eye-medications of its Ophthalmology business, in medical aesthetics and therapeutic products of its Global Solta business, and in certain branded pharmaceutical products of its Salix, Ortho Dermatologics and Dentistry businesses. These revenues declines are expected, as the offices of many health care providers are closed and certain surgeries and elective medical procedures are being deferred. To date, the COVID-19 pandemic appears to have had only a limited impact on the revenues of the Company's Xifaxan ® products. Based on its assessment the Company believes its revenues will be most impacted by the pandemic during the second quarter, as the infection rate of the COVID-19 virus accelerated in March into April, and the virus had spread beyond Asia into different geographies, including the U.S. and Europe, and the number of shelter-in-place directives issued by local authorities increased. Although the affected businesses and geographies are expected to recover at different rates, overall the Company anticipates that the negative trend in revenues will begin to stabilize during its second quarter and continue into its third quarter with the revenues of all businesses possibly returning to pre-pandemic levels as early as late 2020, but, if not, then in 2021. This assessment assumes, among other matters, that the precautionary measures taken by the public are successful in decelerating the spread of the virus, there will be no resurgence of the virus in the second half of 2020 that will lead to significant social restrictions, there will be no significant social restrictions in place at the end of 2020, responses from governments and private sector participants will be successful in bringing about a quick orderly recovery of the global economy, there will be no major interruptions in the Company's supply, manufacturing and distribution channels and the Company continues to execute on its strategies in response to the pandemic. The Company's latest forecasts of cash flows gives consideration to the nature and timing of the expected revenue losses disclosed above. The changes in the amounts and timing of these revenues as presented in the latest forecasts include a range of potential outcomes and are not substantial enough to materially adversely affect the recoverability of any of the associated reporting units’ assets and are not material enough to indicate that the fair values of those reporting units might be below their respective carrying values. Based on the results of the October 1, 2019 annual goodwill impairment test, the Company performed qualitative interim assessments of the respective carrying values and fair values of the Ortho Dermatologics reporting unit and the Neuro and Other reporting unit as of March 31, 2020 to determine if quantitative fair value testing was warranted. As part of these qualitative assessments, management considered the totality of all relevant events or circumstances that effect the carrying amount or fair value of each reporting unit, including comparing the reporting units’ operating results to the forecast used to test the goodwill of the Ortho Dermatologics reporting unit and the Neuro and Other reporting unit as of October 1, 2019. Management believed that based on its qualitative assessment, it was more likely than not that the carrying amount of the Neuro and Other reporting unit was less than its fair value and, therefore, concluded a quantitative assessment was not required at March 31, 2020 . However, the operating results for the Ortho Dermatologics reporting unit for three months ended March 31, 2020 were less than those forecasted as of October 1, 2019 for the same period. Further, the Company adjusted its forecasted cash flows for the Ortho Dermatologics reporting unit for the wide range of potential impacts of the COVID-19 pandemic and longer launch cycles for certain new products. These factors are indicators that there is less headroom as of March 31, 2020 as compared to the headroom calculated on the date goodwill was last tested for impairment. Therefore, a quantitative fair value test for the Ortho Dermatologics reporting unit was performed. The quantitative fair value test utilized the Company's most recent cash flow projections, including a range of potential outcomes, along with a long-term growth rate of 2.0% and a range of discount rates between 9.5% and 10.0% . Based on the quantitative test, the fair value of the Ortho Dermatologics reporting unit continued to be greater than its carrying value and as a result, there was no impairment to the goodwill of the reporting unit, however, the headroom was reduced from the prior year’s assessment. The Company continues to monitor the market conditions impacting the Ortho Dermatologics reporting unit and Neuro and Other reporting unit including: (i) the impacts of the COVID-19 pandemic on operations, (ii) the impact of the loss of exclusivity of certain products, (iii) the impact of longer launch cycles for new products and (iv) ongoing pricing pressures, which could negatively impact the reporting units' results over the long term. If market conditions further deteriorate, if the factors and circumstances regarding the COVID-19 pandemic escalate beyond management’s current expectations, or if the Company is unable to execute its strategies, it may be necessary to record impairment charges in the future and those charges can be material. No other events occurred or circumstances changed during the period October 1, 2019 (the date goodwill was last tested for impairment) through March 31, 2020 that indicate it is more likely than not the fair value of any reporting unit, other than the Ortho Dermatologics reporting unit may be below its carrying value. Accumulated goodwill impairment charges through March 31, 2020 were $3,711 million .

These affirmative and negative covenants include, among other things, and subject to certain qualifications and exceptions, covenants that restrict the Company’s ability and the ability of its subsidiaries to: incur or guarantee additional indebtedness; create or permit liens on assets; pay dividends on capital stock or redeem, repurchase or retire capital stock or subordinated indebtedness; make certain investments and other restricted payments; engage in mergers, acquisitions, consolidations and amalgamations; transfer and sell certain assets; and engage in transactions with affiliates. The 2023 Revolving Credit Facility (as defined below) also contains a financial maintenance covenant that requires the Company to maintain a first lien net leverage ratio of not greater than 4.00 :1.00. The financial maintenance covenant may be waived or amended without the consent of the term loan facility lenders and contains a customary term loan facility standstill. In March 2020, the World Health Organization declared COVID-19 a global pandemic, resulting in an adverse impact on the global economy. While there are a number of standard borrowing conditions that must be met to make borrowings under the 2023 Revolving Credit Facility, the Company has considered the economy's impact on its non-financial and financial maintenance covenants and believes the current state of the economy does not limit its access to capital under the 2023 Revolving Credit Facility at this time. As of March 31, 2020 , the Company was in compliance with its financial maintenance covenant related to its debt obligations. The Company, based on its current forecast as adjusted for the potential impacts of the COVID-19 pandemic, expects to remain in compliance with its financial maintenance covenant and meet its debt service obligations for at least the twelve months following the date of issuance of these financial statements. The Company continues to take steps to improve its operating results to ensure continual compliance with its financial maintenance covenant and may take other actions to reduce its debt levels to align with the Company’s long-term strategy, including divesting other businesses, refinancing debt and issuing equity or equity-linked securities as deemed appropriate. Senior Secured Credit Facilities On June 1, 2018, the Company and certain of its subsidiaries as guarantors entered into the “Senior Secured Credit Facilities” under the Company’s Fourth Amended and Restated Credit and Guaranty Agreement, as amended by the First Incremental Amendment to the Restated Credit Agreement, dated as of November 27, 2018, and as further amended (the “Restated Credit Agreement”) with a syndicate of financial institutions and investors as lenders. The Restated Credit Agreement provides for a revolving credit facility of $1,225 million , which matures on the earlier of June 1, 2023 and the date that is 91 calendar days prior to the scheduled maturity of indebtedness for borrowed money of the Company and Bausch Health Americas, Inc. ("BHA") in an aggregate principal amount in excess of $1,000 million (the "2023 Revolving Credit Facility") and term loan facilities of original principal amounts of $4,565 million and $1,500 million , maturing in June 2025 (the “ June 2025 Term Loan B Facility ”) and November 2025 (the " November 2025 Term Loan B Facility "), respectively. Both the Company and BHA are borrowers under the 2023 Revolving Credit Facility, borrowings under which may be made in U.S. dollars, Canadian dollars or euros. Current Description of Senior Secured Credit Facilities Borrowings under the Senior Secured Credit Facilities in U.S. dollars bear interest at a rate per annum equal to, at the Company's option, either: (i) a base rate determined by reference to the highest of: (a) the prime rate (as defined in the Restated Credit Agreement), (b) the federal funds effective rate plus 1/2 of 1.00% or (c) the eurocurrency rate (as defined in the Restated Credit Agreement) for a period of one month plus 1.00% (or if such eurocurrency rate shall not be ascertainable, 1.00% ) or (ii) a eurocurrency rate determined by reference to the costs of funds for U.S. dollar deposits for the interest period relevant to such borrowing adjusted for certain additional costs (provided however, that the eurocurrency rate shall at no time be less than 0.00% per annum), in each case plus an applicable margin. Borrowings under the 2023 Revolving Credit Facility in euros bear interest at a eurocurrency rate determined by reference to the costs of funds for euro deposits for the interest period relevant to such borrowing (provided however, that the eurocurrency rate shall at no time be less than 0.00% per annum), plus an applicable margin. Borrowings under the 2023 Revolving Credit Facility in Canadian dollars bear interest at a rate per annum equal to, at the Company's option, either: (i) a prime rate determined by reference to the higher of: (a) the rate of interest last quoted by The Wall Street Journal as the “Canadian Prime Rate” or, if The Wall Street Journal ceases to quote such rate, the highest per annum interest rate published by the Bank of Canada as its prime rate and (b) the 1 month BA rate (as defined below) calculated daily plus 1.00% (provided however, that the prime rate shall at no time be less than 0.00% ) or (ii) the bankers’ acceptance rate for Canadian dollar deposits in the Toronto interbank market (the “BA rate”) for the interest period relevant to such borrowing (provided however, that the BA rate shall at no time be less than 0.00% per annum), in each case plus an applicable margin. Subject to certain exceptions and customary baskets set forth in the Restated Credit Agreement, the Company is required to make mandatory prepayments of the loans under the Senior Secured Credit Facilities under certain circumstances, including from: (i) 100% of the net cash proceeds of insurance and condemnation proceeds for property or asset losses (subject to reinvestment rights and net proceeds threshold), (ii) 100% of the net cash proceeds from the incurrence of debt (other than permitted debt as described in the Restated Credit Agreement), (iii) 50% of Excess Cash Flow (as defined in the Restated Credit Agreement) subject to decrease based on leverage ratios and subject to a threshold amount and (iv) 100% of net cash proceeds from asset sales (subject to reinvestment rights). These mandatory prepayments may be used to satisfy future amortization. The applicable interest rate margins for the June 2025 Term Loan B Facility and the November 2025 Term Loan B Facility are 2.00% and 1.75% , respectively, with respect to base rate and prime rate borrowings and 3.00% and 2.75% , respectively, with respect to eurocurrency rate and BA rate borrowings. As of March 31, 2020 , the stated rates of interest on the Company’s borrowings under the June 2025 Term Loan B Facility and the November 2025 Term Loan B Facility were 3.61% and 3.36% per annum, respectively. The amortization rate for both the June 2025 Term Loan B Facility and the November 2025 Term Loan B Facility is 5.00% per annum. The Company may direct that prepayments be applied to such amortization payments in order of maturity. As of March 31, 2020 , the aggregate remaining mandatory quarterly amortization payments for the Senior Secured Credit Facilities were $1,023 million through November 1, 2025. The applicable interest rate margins for borrowings under the 2023 Revolving Credit Facility are 1.50% - 2.00% with respect to base rate or prime rate borrowings and 2.50% - 3.00% with respect to eurocurrency rate or BA rate borrowings. As of March 31, 2020 , the stated rate of interest on the 2023 Revolving Credit Facility was 3.36% per annum. As of March 31, 2020 , the Company had no outstanding borrowings, $168 million of issued and outstanding letters of credit and remaining availability of $1,057 million under its 2023 Revolving Credit Facility. In addition, the Company is required to pay commitment fees of 0.25% - 0.50% per annum with respect to the unutilized commitments under the 2023 Revolving Credit Facility, payable quarterly in arrears. The Company also is required to pay: (i) letter of credit fees on the maximum amount available to be drawn under all outstanding letters of credit in an amount equal to the applicable margin on eurocurrency rate borrowings under the 2023 Revolving Credit Facility on a per annum basis, payable quarterly in arrears, (ii) customary fronting fees for the issuance of letters of credit and (iii) agency fees. The Restated Credit Agreement permits the incurrence of incremental credit facility borrowings up to the greater of $1,000 million and 28.5% of Consolidated Adjusted EBITDA (as defined in the Restated Credit Agreement), subject to customary terms and conditions, as well as the incurrence of additional incremental credit facility borrowings subject to a secured leverage ratio of not greater than 3.50 : 1.00 , and, in the case of unsecured debt, a total leverage ratio of not greater than 6.50 : 1.00 or an interest coverage ratio of not less than 2.00 : 1.00 . Senior Secured Notes The Senior Secured Notes are guaranteed by each of the Company’s subsidiaries that is a guarantor under the Restated Credit Agreement and existing Senior Unsecured Notes (together, the “Note Guarantors”). The Senior Secured Notes and the guarantees related thereto are senior obligations and are secured, subject to permitted liens and certain other exceptions, by the same first priority liens that secure the Company’s obligations under the Restated Credit Agreement under the terms of the indentures governing the Senior Secured Notes. The Senior Secured Notes and the guarantees rank equally in right of repayment with all of the Company’s and Note Guarantors’ respective existing and future unsubordinated indebtedness and senior to the Company’s and Note Guarantors’ respective future subordinated indebtedness. The Senior Secured Notes and the guarantees related thereto are effectively pari passu with the Company’s and the Note Guarantors’ respective existing and future indebtedness secured by a first priority lien on the collateral securing the Senior Secured Notes and effectively senior to the Company’s and the Note Guarantors’ respective existing and future indebtedness that is unsecured, including the existing Senior Unsecured Notes, or that is secured by junior liens, in each case to the extent of the value of the collateral. In addition, the Senior Secured Notes are structurally subordinated to: (i) all liabilities of any of the Company’s subsidiaries that do not guarantee the Senior Secured Notes and (ii) any of the Company’s debt that is secured by assets that are not collateral. Upon the occurrence of a change in control (as defined in the indentures governing the Senior Secured Notes), unless the Company has exercised its right to redeem all of the notes of a series, holders of the Senior Secured Notes may require the Company to repurchase such holder’s notes, in whole or in part, at a purchase price equal to 101% of the principal amount thereof plus accrued and unpaid interest. 5.75% Senior Secured Notes due 2027 - March 2019 Refinancing Transactions On March 8, 2019, BHA and the Company issued: (i) $1,000 million aggregate principal amount of 8.50% Senior Unsecured Notes due January 2027 (the "January 2027 Unsecured Notes") and (ii) $500 million aggregate principal amount of 5.75% Senior Secured Notes due August 2027 (the "August 2027 Secured Notes"), respectively, in a private placement. A portion of the proceeds, and cash on hand, were used to: (i) repurchase $584 million of 5.875% Senior Unsecured Notes due 2023 (the "May 2023 Unsecured Notes"), (ii) repurchase $518 million of 5.625% Senior Unsecured Notes due 2021 (the “December 2021 Unsecured Notes”), (iii) repurchase $216 million of 5.50% Senior Unsecured Notes due 2023 (the "March 2023 Unsecured Notes”) and (iv) pay all fees and expenses associated with these transactions (collectively, the “ March 2019 Refinancing Transactions ”). During April 2019, the Company redeemed $182 million of the December 2021 Unsecured Notes, representing the remaining outstanding principal balance of the December 2021 Unsecured Notes and completing the refinancing of $1,500 million of debt in connection with the March 2019 Refinancing Transactions . Senior Unsecured Notes The Senior Unsecured Notes issued by the Company are the Company’s senior unsecured obligations and are jointly and severally guaranteed on a senior unsecured basis by each of its subsidiaries that is a guarantor under the Senior Secured Credit Facilities. The Senior Unsecured Notes issued by BHA are senior unsecured obligations of BHA and are jointly and severally guaranteed on a senior unsecured basis by the Company and each of its subsidiaries (other than BHA) that is a guarantor under the Senior Secured Credit Facilities. Future subsidiaries of the Company and BHA, if any, may be required to guarantee the Senior Unsecured Notes. If the Company experiences a change in control, the Company may be required to make an offer to repurchase each series of Senior Unsecured Notes, in whole or in part, at a purchase price equal to 101% of the aggregate principal amount of the Senior Unsecured Notes repurchased, plus accrued and unpaid interest. 8.50% Senior Unsecured Notes due 2027 - March 2019 Refinancing Transactions As part of the March 2019 Refinancing Transactions described above, BHA issued $1,000 million aggregate principal amount of January 2027 Unsecured Notes. These are additional notes and form part of the same series as BHA’s existing January 2027 Unsecured Notes. 7.00% Senior Unsecured Notes due 2028 and 7.25% Senior Unsecured Notes due 2029 - May 2019 Refinancing Transactions On May 23, 2019, the Company issued: (i) $750 million aggregate principal amount of 7.00% Senior Unsecured Notes due January 2028 (the " 7.00% January 2028 Unsecured Notes") and (ii) $750 million aggregate principal amount of 7.25% Senior Unsecured Notes due May 2029 (the "May 2029 Unsecured Notes"), respectively, in a private placement. The proceeds and cash on hand, were used to: (i) repurchase $1,118 million of May 2023 Unsecured Notes, (ii) repurchase $382 million of March 2023 Unsecured Notes and (iii) pay all fees and expenses associated with these transactions (collectively, the “ May 2019 Refinancing Transactions ”). 5.00% Senior Unsecured Notes due 2028 and 5.25% Senior Unsecured Notes due 2030 - December 2019 Financing and Refinancing Transactions On December 30, 2019, the Company issued: (i) $1,250 million aggregate principal amount of 5.00% Senior Unsecured Notes due January 2028 (the " 5.00% January 2028 Unsecured Notes") and (ii) $1,250 million aggregate principal amount of 5.25% Senior Unsecured Notes due January 2030 (the "January 2030 Unsecured Notes") in a private placement. The proceeds and cash on hand were used to: (i) redeem $1,240 million of May 2023 Unsecured Notes on January 16, 2020, (ii) finance the $1,210 million settlement of certain U.S. securities litigation, subject to final court approval, as discussed in Note 18, "LEGAL PROCEEDINGS" and (iii) pay all fees and expenses associated with these transactions (collectively, the "December 2019 Financing and Refinancing Transactions"). Weighted Average Stated Rate of Interest The weighted average stated rate of interest for the Company's outstanding debt obligations as of March 31, 2020 and December 31, 2019 was 6.01% and 6.21% , respectively. Maturities and Mandatory Payments In order to reduce future cash interest payments, as well as future maturities and mandatory payments, the Company may, from time to time, purchase outstanding debt for cash in open market purchases or privately negotiated transactions. Such repurchases or exchanges, if any, will depend on prevailing market conditions, future liquidity requirements, contractual restrictions and other factors. During the three months ended March 31, 2020 , the Company repurchased and retired, outstanding senior unsecured notes with an aggregate par value of $17 million in the open market, for an aggregate cost of $16 million . In connection with these repurchases, the Company recognized a gain of $1 million included in Loss on extinguishment of debt . Maturities and mandatory payments of debt obligations for the remainder of 2020 , the five succeeding years ending December 31 and thereafter are as follows: (in millions) Remainder of 2020 $ 4 2021 — 2022 1,553 2023 2,447 2024 2,303 2025 10,632 Thereafter 7,762 Total debt obligations 24,701 Unamortized premiums, discounts and issuance costs (273 ) Total long-term debt and other $ 24,428

Share-based Payment Arrangement [Abstract]
SHARE-BASED COMPENSATION	SHARE-BASED COMPENSATION In May 2014, shareholders approved the Company’s 2014 Omnibus Incentive Plan (the “2014 Plan”) which replaced the Company’s 2011 Omnibus Incentive Plan (the “2011 Plan”) for future equity awards granted by the Company. The Company transferred the common shares available under the 2011 Plan to the 2014 Plan. The maximum number of common shares that may be issued to participants under the 2014 Plan was equal to 18,000,000 common shares, plus the number of common shares under the 2011 Plan reserved but unissued and not underlying outstanding awards and the number of common shares becoming available for reuse after awards are terminated, forfeited, cancelled, exchanged or surrendered under the 2011 Plan and the Company’s 2007 Equity Compensation Plan. The Company registered 20,000,000 common shares of common stock for issuance under the 2014 Plan. Effective April 30, 2018, the Company amended and restated the 2014 Plan (the “Amended and Restated 2014 Plan”). The Amended and Restated 2014 Plan includes the following amendments: (i) the number of common shares authorized for issuance under the Amended and Restated 2014 Plan has been increased by an additional 11,900,000 common shares, as approved by the requisite number of shareholders at the Company’s annual general meeting held on April 30, 2018, (ii) introduction of a $750,000 aggregate fair market value limit on awards (in either equity, cash or other compensation) that can be granted in any calendar year to a participant who is a non-employee director, (iii) housekeeping changes to address recent changes to Section 162(m) of the Internal Revenue Code, (iv) awards are expressly subject to the Company’s clawback policy and (v) awards not assumed or substituted in connection with a Change of Control (as defined in the Amended and Restated 2014 Plan) will only vest on a pro rata basis. Approximately 3,892,000 common shares were available for future grants as of March 31, 2020 . The Company uses reserved and unissued common shares to satisfy its obligations under its share-based compensation plans. Effective April 28, 2020, the Company further amended and restated the Amended and Restated 2014 Plan (the “Further Amended and Restated 2014 Plan”). The Further Amended and Restated 2014 Plan includes the following amendments: (i) the number of common shares authorized for issuance under the Further Amended and Restated 2014 Plan has been increased by an additional 13,500,000 common shares, as approved by the requisite number of shareholders at the Company’s annual general meeting held on April 28, 2020, (ii) the exercise price of stock options and share appreciation rights (“SARs”) will be based on the closing price of the underlying common shares on the date such stock options or SARs are granted (rather than on the last preceding trading date), (iii) additional provisions clarifying that: (a) stock options and SARs will not be eligible for the payment of dividend or dividend equivalents and (b) the Talent and Compensation Committee of the Board of Directors of the Company cannot, without shareholder approval, seek to effect any repricing of any previously granted “underwater” stock option or SAR and (iv) other housekeeping and/or clerical changes. The Company has a long-term incentive program with the objective of realigning the share-based awards granted to senior management with the Company’s focus on improving its tangible capital usage and allocation while maintaining focus on improving total shareholder return over the long-term. The share-based awards granted under this long-term incentive program consist of time-based stock options, time-based restricted share units (“RSUs”) and performance-based RSUs. Performance-based RSUs are comprised of: (i) awards that vest upon achievement of certain share price appreciation conditions that are based on total shareholder return (“TSR”) and (ii) awards that vest upon attainment of certain performance targets that are based on the Company’s return on tangible capital (“ROTC”). The following table summarizes the components and classification of share-based compensation expense related to stock options and RSUs for the three months ended March 31, 2020 and 2019 : Three Months Ended (in millions) 2020 2019 Stock options $ 4 $ 6 RSUs 23 18 $ 27 $ 24 Research and development expenses $ 3 $ 2 Selling, general and administrative expenses 24 22 $ 27 $ 24 Share-based awards granted consist of: Three Months Ended March 31, 2020 2019 Stock options Granted 2,260,000 1,684,000 Weighted-average exercise price $ 24.77 $ 23.16 Weighted-average grant date fair value $ 6.60 $ 8.47 Time-based RSUs Granted 2,453,000 2,401,000 Weighted-average grant date fair value $ 23.37 $ 24.05 TSR performance-based RSUs Granted 425,000 454,000 Weighted-average grant date fair value $ 26.13 $ 34.53 ROTC performance-based RSUs Granted 472,000 505,000 Weighted-average grant date fair value $ 27.05 $ 25.03 As of March 31, 2020 , the remaining unrecognized compensation expense related to all outstanding non-vested stock options, time-based RSUs and performance-based RSUs amounted to $161 million , which will be amortized over a weighted-average period of 1.95 years.

INCOME TAXES

INCOME TAXES	3 Months Ended
	Mar. 31, 2020
Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES For interim financial statement purposes, U.S. GAAP income tax expense/benefit related to ordinary income is determined by applying an estimated annual effective income tax rate against a company's ordinary income, subject to certain limitations on the benefit of losses. Income tax expense/benefit related to items not characterized as ordinary income is recognized as a discrete item when incurred. The estimation of the Company's income tax provision requires the use of management forecasts and other estimates, application of statutory income tax rates, and an evaluation of valuation allowances. The Company's estimated annual effective income tax rate may be revised, if necessary, in each interim period. Benefit from income taxes for the three months ended March 31, 2020 was $26 million and included: (i) $21 million of net income tax benefit for discrete items, which includes: (a) $10 million in tax benefits recognized for changes in uncertain tax positions, (b) a $5 million tax benefit related to a deduction for stock compensation and (c) $4 million of net tax benefits associated with filing certain tax returns and (ii) $5 million of income tax benefit for the Company's ordinary loss during the three months ended March 31, 2020 . Benefit from income taxes for the three months ended March 31, 2019 was $74 million and included: (i) $51 million of net income tax expense for discrete items, which includes: (a) $32 million of tax benefit recognized upon a ruling from the Polish tax authorities confirming the deductibility of royalty payments by an affiliate, (b) $15 million of net tax benefits associated with filing certain tax returns and (c) $4 million in tax benefits recognized for changes in uncertain tax positions and (ii) $23 million of income tax benefit for the Company's ordinary loss during the three months ended March 31, 2019 . The Company records a valuation allowance against its deferred tax assets to reduce the net carrying value to an amount that it believes is more likely than not to be realized. When the Company establishes or reduces the valuation allowance against its deferred tax assets, the provision for income taxes will increase or decrease, respectively, in the period such determination is made except that, as a result of the 2018 adoption of guidance regarding intra-entity transfers, any change in valuation allowance surrounding the adoption of the intra-entity transfer resulting from this adoption was recorded within equity. The valuation allowance against deferred tax assets was $2,824 million and $2,831 million as of March 31, 2020 and December 31, 2019 , respectively. The decrease was primarily due to income in Canada. The Company will continue to assess the need for a valuation allowance on a go-forward basis. As of March 31, 2020 and December 31, 2019 , the Company had $967 million and $1,002 million of unrecognized tax benefits, which included $46 million and $45 million of interest and penalties, respectively. Of the total unrecognized tax benefits as of March 31, 2020 , $321 million would reduce the Company’s effective tax rate, if recognized. The Company believes that it is reasonably possible that the total amount of unrecognized tax benefits at March 31, 2020 could decrease by approximately $110 million in the next 12 months as a result of the resolution of certain tax audits and other events. The Company continues to be under examination by the Canada Revenue Agency. The Company’s position as of March 31, 2020 with regard to proposed audit adjustments has not changed and the proposed adjustments continue to result primarily in a loss of tax attributes that are subject to a full valuation allowance. The Internal Revenue Service completed its examinations of the Company’s U.S. consolidated federal income tax returns for the years 2013 and 2014. There were no material adjustments to the Company's taxable income as a result of these examinations. The 2014 tax year remains open to the extent of a 2017 capital loss carried back to that year. Additionally, the Internal Revenue Service has selected for examination the Company's annual tax filings for 2015 and 2016 and the Company's short period tax return for the period ended September 8, 2017, which was filed as a result of the Company's internal restructuring efforts during 2017. At this time, the Company does not expect that proposed adjustments, if any, for these periods would be material to the Company's Consolidated Financial Statements. The Company's U.S. affiliates remain under examination for various state tax audits in the U.S. for years 2012 through 2017. The Company’s subsidiaries in Germany are under audit for tax years 2014 through 2016. At this time, the Company does not expect that proposed adjustments, if any, would be material to the Company's Consolidated Financial Statements. The Company’s subsidiaries in Australia are under audit by the Australian Tax Office for various years beginning in 2010. At this time, the Company does not expect that proposed adjustments, if any, would be material to the Company's Consolidated Financial Statements. Certain affiliates of the Company in regions outside of Canada, the U.S., Germany and Australia are currently under examination by relevant taxing authorities, and all necessary accruals have been recorded, including uncertain tax benefits. At this time, the Company does not expect that proposed adjustments, if any, would be material to the Company's Consolidated Financial Statements.

LOSS PER SHARE	LOSS PER SHARE Loss per share attributable to Bausch Health Companies Inc. were calculated as follows: Three Months Ended (in millions, except per share amounts) 2020 2019 Net loss attributable to Bausch Health Companies Inc. $ (152 ) $ (52 ) Basic and diluted weighted-average common shares outstanding 353.4 351.3 Basic and diluted loss per share attributable to Bausch Health Companies Inc. $ (0.43 ) $ (0.15 ) During the three months ended March 31, 2020 and 2019 , all potential common shares issuable for stock options and RSUs were excluded from the calculation of diluted loss per share, as the effect of including them would have been anti-dilutive. The dilutive effect of potential common shares issuable for stock options and RSUs on the weighted-average number of common shares outstanding would have been approximately 5,207,000 and 4,920,000 common shares for the three months ended March 31, 2020 and 2019 , respectively. During the three months ended March 31, 2020 and 2019 , time-based RSUs, performance-based RSUs and stock options to purchase approximately 9,561,000 and 5,370,000 common shares, respectively, were not included in the computation of diluted earnings per share because the effect would have been anti-dilutive under the treasury stock method.

LEGAL PROCEEDINGS

Commitments and Contingencies Disclosure [Abstract]
LEGAL PROCEEDINGS	LEGAL PROCEEDINGS From time to time, the Company becomes involved in various legal and administrative proceedings, which include product liability, intellectual property, commercial, tax, antitrust, governmental and regulatory investigations, related private litigation and ordinary course employment-related issues. From time to time, the Company also initiates actions or files counterclaims. The Company could be subject to counterclaims or other suits in response to actions it may initiate. The Company believes that the prosecution of these actions and counterclaims is important to preserve and protect the Company, its reputation and its assets. Certain of these proceedings and actions are described in Note 21, “LEGAL PROCEEDINGS,” to the Company's Consolidated Financial Statements included in the Company's Annual Report on Form 10-K for the year ended December 31, 2019, filed with the SEC on February 19, 2020. Except as described below, there have been no material updates or developments with respect to any such proceedings or actions during the three months ended March 31, 2020. On a quarterly basis, the Company evaluates developments in legal proceedings, potential settlements and other matters that could increase or decrease the amount of the liability accrued. As of March 31, 2020 , the Company's Consolidated Balance Sheets includes accrued current loss contingencies of $1,416 million related to matters which are both probable and reasonably estimable. For all other matters, unless otherwise indicated, the Company cannot reasonably predict the outcome of these legal proceedings, nor can it estimate the amount of loss, or range of loss, if any, that may result from these proceedings. An adverse outcome in certain of these proceedings could have a material adverse effect on the Company’s business, financial condition and results of operations, and could cause the market value of its common shares and/or debt securities to decline. Governmental and Regulatory Inquiries SEC Investigation Beginning in November 2015, the Company received from the staff of the Los Angeles Regional Office of the SEC subpoenas for documents, as well as various document, testimony and interview requests, related to its investigation of the Company, including requests concerning the Company's former relationship with Philidor Rx Services, LLC ("Philidor"), its accounting practices and policies, its public disclosures and other matters. On March 27, 2020, the staff of the SEC’s Los Angeles Regional Office issued a Wells Notice informing the Company that they had reached a preliminary determination to recommend that the SEC bring charges against the Company for violating the federal securities laws as a result of SEC filings and other statements made by Valeant and its former executives in 2014-2015 concerning Philidor, as well as other accounting and disclosure matters. The Company continues to cooperate with the SEC in this matter, has responded to the Wells Notice and continues to engage in settlement discussions with the staff. The Company has agreed to a tolling agreement with the SEC regarding these potential claims. Although the Company cannot predict the outcome or the duration of the SEC investigation or any other legal proceedings or any enforcement actions or other remedies that may be imposed on the Company arising out of the SEC investigation, the Company expects that it will likely result in damages, settlement payments, fines, penalties, consent orders or other administrative sanctions against the Company and/or certain of its former legacy directors and officers, any of which could be material. As a result, although no agreement has been reached, the Company has recorded an estimated liability based on these discussions which is included in the Company's accrued current loss contingencies. The final resolution may differ from the Company's current estimate and it could be material to the Company’s results of operations. As referenced above, during the three months ended March 31, 2020 , there have been no material updates or developments with respect to certain other proceedings or actions as described under “ Governmental and Regulatory Inquiries” in Note 21, “LEGAL PROCEEDINGS,” to the Company's Consolidated Financial Statements included in the Company's Annual Report on Form 10-K for the year ended December 31, 2019, filed with the SEC on February 19, 2020. Such matters include: AMF Investigation On April 12, 2016, the Company received a letter from the Autorité des marchés financiers (the “AMF”) requesting documents concerning the work of the Company’s ad hoc committee of independent directors, the Company’s former relationship with Philidor, the Company's accounting practices and policies and other matters. In July 2018, the Company was advised by the AMF that it had issued a formal investigation order against it. Investigation by the U.S. Attorney's Office for the District of Massachusetts - re Arestin ® In August 2019, the Company received a subpoena from the U.S. Attorney's Office for the District of Massachusetts, requesting materials including documents concerning the sales, marketing, coverage and reimbursement of Arestin ® , including related support services, and other matters. The Company is cooperating with all these investigations. The Company cannot predict the outcome or the duration of these investigations or any other legal proceedings or any enforcement actions or other remedies that may be imposed on the Company arising out of this investigation. Securities and RICO Class Actions and Related Matters U.S. Securities Litigation - Opt-Out Litigation On December 16, 2019, the Company announced that it had agreed to settle, subject to final court approval, the consolidated securities class action filed in the U.S. District Court for the District of New Jersey (In re Valeant Pharmaceuticals International, Inc. Securities Litigation, Case No. 15-cv-07658). In October 2015, four putative securities class actions were filed in the U.S. District Court for the District of New Jersey against the Company and certain current or former officers and directors. The allegations related to, among other things, allegedly false and misleading statements and/or failures to disclose information about the Company’s business and prospects, including relating to drug pricing, the Company’s use of specialty pharmacies, and the Company’s relationship with Philidor. On May 31, 2016, the court entered an order consolidating the four actions under the caption In re Valeant Pharmaceuticals International, Inc. Securities Litigation, Case No. 15-cv-07658. On June 24, 2016, the lead plaintiff filed a consolidated complaint asserting claims under Sections 10(b) and 20(a) of the Exchange Act against the Company, and certain current or former officers and directors, as well as claims under Sections 11, 12(a)(2) and 15 of the Securities Act of 1933 (the “Securities Act”) against the Company, certain current or former officers and directors, and certain other parties. The lead plaintiff seeks to bring these claims on behalf of a putative class of persons who purchased the Company’s equity securities and senior notes in the United States between January 4, 2013 and March 15, 2016, including all those who purchased the Company’s securities in the United States in the Company’s debt and stock offerings between July 2013 to March 2015. On September 13, 2016, the Company and the other defendants moved to dismiss the consolidated complaint. On April 28, 2017, the court dismissed certain claims arising out of the Company's private placement offerings and otherwise denied the motions to dismiss. On September 20, 2018, lead plaintiff filed an amended complaint, adding claims against ValueAct Capital Management L.P. and affiliated entities ("ValueAct"). On October 31, 2018, a third-party defendant, ValueAct, filed a motion to dismiss. On June 30, 2019, the Court denied the motion to dismiss. On December 16, 2019, the Company, the current or former officers and directors, ValueAct, and the underwriters announced that they agreed to resolve the securities action for $1,210 million , subject to final court approval. Once approved by the court, the settlement will resolve and discharge all claims against the Company in the class action. As part of the settlement, the Company and the other settling defendants admitted no liability as to the claims against it and deny all allegations of wrongdoing. On January 27, 2020 the court preliminarily approved the settlement and scheduled the final settlement approval hearing for May 27, 2020. In order to qualify for a settlement payment all persons and entities that purchased or otherwise acquired the Company securities during the class period must have submitted a proof of claim and release form by May 6, 2020. The settlement payment is being paid in accordance with the payment schedule outlined in the settlement agreement. The opt-out litigations discussed below remain ongoing. On June 6, 2018, a putative class action was filed in the U.S. District Court for the District of New Jersey against the Company and certain current or former officers and directors. This action, captioned Timber Hill LLC, v. Valeant Pharmaceuticals International, Inc., et al., (Case No. 18-cv-10246) (“Timber Hill”), asserts securities fraud claims under Sections 10(b) and 20(a) of the Exchange Act on behalf of a putative class of persons who purchased call options or sold put options on the Company’s common stock during the period January 4, 2013 through August 11, 2016. On June 11, 2018, this action was consolidated with In re Valeant Pharmaceuticals International, Inc. Securities Litigation, (Case No. 15-cv-07658). On January 14, 2019, the defendants filed a motion to dismiss the Timber Hill complaint. Briefing on that motion was completed on February 13, 2019. On August 15, 2019, the Court denied the motion to dismiss the Timber Hill action, holding that this complaint was a legal nullity as a result of the June 11, 2018 consolidation order. In addition to the consolidated putative class action, thirty-five groups of individual investors in the Company’s stock and debt securities have chosen to opt out of the consolidated putative class action and filed securities actions in the U.S. District Court for the District of New Jersey against the Company and certain current or former officers and directors. In addition to the matters captioned Maverick Neutral Levered Fund v. Valeant Pharmaceuticals International, Inc. (Case No. 20-cv-02190) (“Maverick”) and Templeton v. Valeant Pharmaceuticals International, Inc. (Case No. 20-cv-05478) (“Templeton”), these actions were captioned previously in the Company’s Annual Report on Form 10K for the year ended December 31, 2019, filed on February 19, 2020. Two of the thirty-five opt out actions have been dismissed; and while the total number of remaining opt out actions pending in the District of New Jersey is thirty-three actions, the Company has reached agreement in principle to resolve several of these actions and expects those actions to be dismissed shortly. These individual shareholder actions assert claims under Sections 10(b), and 20(a) of the Exchange Act. Certain of these individual actions assert additional claims, including claims under Section 18 of the Exchange Act, Sections 11, 12(a)(2), and 15 of the Securities Act, common law fraud, negligent misrepresentation, claims under the New Jersey Racketeer Influenced and Corrupt Organizations Act and one plaintiff asserts claims under the Connecticut Uniform Securities Act. These claims are based on alleged purchases of Company stock, options, and/or debt at various times between January 3, 2013 and August 10, 2016. The allegations in the complaints are similar to those made by plaintiffs in the putative class action. Motions to dismiss have been filed and in most cases decided in many of these individual actions. To date, the Court has dismissed state law claims including New Jersey Racketeer Influenced and Corrupt Organizations Act, common law fraud, and negligent misrepresentation claims in certain cases. On January 7, 2019, the Court entered a stipulation of voluntary dismissal in the Senzar Healthcare Master Fund LP v. Valeant Pharmaceuticals International, Inc. (Case No. 18-cv-02286) opt-out action, closing the case. On September 10, 2019, the Court granted defendants’ motion to dismiss all claims in the Bahaa Aly v. Valeant Pharmaceuticals International, Inc. (“Aly”) (Case No. 18-cv-17393) opt-out action. On October 9, 2019, the Aly Plaintiffs filed a notice of appeal to the United States Court of Appeals for the Third Circuit. On December 13, 2019, the Court granted the Company’s motion to dismiss the Catalyst complaint in its entirety. The Company disputes the claims against it in the remaining individual opt-out complaints and intends to defend itself vigorously. Canadian Securities Litigation In 2015, six putative class actions were filed and served against the Company and certain current or former officers and directors in Canada in the provinces of British Columbia, Ontario and Quebec. The Company is also aware of two additional putative class actions that were filed with the applicable court but which have not been served on the Company and the factual allegations made in these actions are substantially similar to those outlined above. The actions generally allege violations of Canadian provincial securities legislation on behalf of putative classes of persons who purchased or otherwise acquired securities of the Company for periods commencing as early as January 1, 2013 and ending as late as November 16, 2015. The alleged violations relate to the same matters described in the U.S. Securities Litigation description above. Each of these putative class actions, other than the Catucci action in the Quebec Superior Court, has been discontinued. In the Catucci action, on August 29, 2017, the judge granted the plaintiffs leave to proceed with their claims under the Quebec Securities Act and authorized the class proceeding. On October 26, 2017, the plaintiffs issued their Judicial Application Originating Class Proceedings. In addition to the class proceedings described above, on April 12, 2018, the Company was served with an application for leave filed in the Quebec Superior Court of Justice to pursue an action under the Quebec Securities Act against the Company and certain current or former officers and directors. This proceeding is captioned BlackRock Asset Management Canada Limited et al. v. Valeant, et al. (Court File No. 500-11-054155-185). The allegations in the proceeding are similar to those made by plaintiffs in the Catucci class action. On June 18, 2018, the same BlackRock entities filed an originating application (Court File No. 500-17-103749-183) against the same defendants asserting claims under the Quebec Civil Code in respect of the same alleged misrepresentations. The Company is aware that certain other members of the Catucci class exercised their opt-out rights prior to the June 19, 2018 deadline. On February 15, 2019, one of the entities which exercised its opt-out rights (“CalSTRS”) served the Company with an application in the Quebec Superior Court of Justice for leave to pursue an action under the Quebec Securities Act against the Company, certain current or former officers and directors of the Company and its auditor. That proceeding is captioned California State Teachers’ Retirement System v. Bausch Health Companies Inc. et al. (Court File No. 500-11-055722-181). The allegations in the proceeding are similar to those made by the plaintiffs in the Catucci class action and in the BlackRock opt-out proceedings. On that same date, CalSTRS also served the Company with proceedings (Court File No. 500-17-106044-186) against the same defendants asserting claims under the Quebec Civil Code in respect of the same alleged misrepresentations. On February 3, 2020, the Quebec Superior Court granted the applications of CalSTRS and BlackRock for leave to pursue their respective actions asserting claims under the Quebec Securities Act. On March 11, 2020, the Company and the other defendants filed applications for leave to appeal from the decision of the Quebec Superior Court. The applications for leave to appeal are scheduled to be heard on June 9, 2020. After a hearing on November 11, 2019, the court approved a settlement in the Catucci action between the class members and the Company’s auditors. The Company believes that it has viable defenses in each of these actions. In each case, the Company intends to defend itself vigorously. Insurance Coverage Lawsuit On December 7, 2017, the Company filed a lawsuit against its insurance companies that issued insurance policies covering claims made against the Company, its subsidiaries, and its directors and officers during two distinct policy periods, (i) 2013-14 and (ii) 2015-16. The lawsuit is currently pending in the United States District Court for the District of New Jersey (Valeant Pharmaceuticals International, Inc., et al. v. AIG Insurance Company of Canada, et al.; 3:18-CV-00493). In the lawsuit, the Company seeks coverage for: (i) the costs of defending and resolving claims brought by former shareholders and debtholders of Allergan, Inc. in In re Allergan, Inc. Proxy Violation Securities Litigation and Timber Hill LLC, individually and on behalf of all others similarly situated v. Pershing Square Capital Management, L.P., et al. (under the 2013-2014 coverage period), and (ii) costs incurred and to be incurred in connection with the securities class actions and opt-out cases described in this section and certain of the investigations described above (under the 2015-2016 coverage period). Derivative Lawsuits On September 10, 2019 and September 13, 2019, two alleged stockholders filed derivative lawsuits purportedly on behalf of the Company against former Company board members and executives. On March 7, 2020, a consolidated amended derivative complaint was filed, captioned In re Bausch Health Companies Inc. F/K/A/ Valeant Pharmaceuticals International, Inc. Stockholder Derivative Litigation (Case No. 19-cv-17833). Plaintiffs assert claims for breach of fiduciary duty, waste of corporate assets, and unjust enrichment related to, among other things, allegedly false and misleading statements and/or failures to disclose information about the Company’s business and prospects, including relating to drug pricing, the Company’s use of specialty pharmacies, and the Company’s relationship with Philidor. The consolidated complaint also asserts a claim for contribution and indemnification by the Defendants for any liability the Company ultimately faces as a result of the conduct alleged in the complaint. The claims alleged in these cases are based on the same purported conduct that is at issue in In re Valeant Pharmaceuticals International, Inc. Securities Litigation , all of which occurred prior to 2017. On April 21, 2020, the Defendants filed a motion to dismiss the consolidated amended complaint. Briefing on this motion will conclude on July 6, 2020. The Company disputes these claims and intends to defend itself vigorously. Other Securities and RICO Class Actions and Related Matters As referenced above during the three months ended March 31, 2020 , there have been no material updates or developments with respect to certain other proceedings or actions as described under “ Securities and RICO Class Actions and Related Matters” in Note 21, “LEGAL PROCEEDINGS,” to the Company's Consolidated Financial Statements included in the Company's Annual Report on Form 10-K for the year ended December 31, 2019, filed with the SEC on February 19, 2020. Such matters include: RICO Class Actions Between May 27, 2016 and September 16, 2016, three actions were filed in the U.S. District Court for the District of New Jersey against the Company and various third-parties (these actions were subsequently consolidated), alleging claims under the federal Racketeer Influenced Corrupt Organizations Act (“RICO”) on behalf of a putative class of certain third-party payors that paid claims submitted by Philidor for certain Company-branded drugs between January 2, 2013 and November 9, 2015. The consolidated complaint alleges, among other things, that the defendants committed predicate acts of mail and wire fraud by submitting or causing to be submitted prescription reimbursement requests that misstated or omitted facts regarding: (1) the identity and licensing status of the dispensing pharmacy; (2) the resubmission of previously denied claims; (3) patient co-pay waivers; (4) the availability of generic alternatives; and (5) the insured’s consent to renew the prescription. The complaint further alleges that these acts constitute a pattern of racketeering or a racketeering conspiracy in violation of the RICO statute and caused plaintiffs and the putative class unspecified damages, which may be trebled under the RICO statute. A decision on the Company’s motion to dismiss this complaint is pending. The Company believes these claims are without merit and intends to defend itself vigorously. Hound Partners Lawsuit In October 2018, Hound Partners Offshore Fund, LP, Hound Partners Long Master, LP, and Hound Partners Concentrated Master, LP, filed a lawsuit against the Company in the Superior Court of New Jersey Law Division/Mercer County that asserts claims for common law fraud, negligent misrepresentation, and violations of the New Jersey Racketeer Influenced and Corrupt Organizations Act. This matter is currently stayed pending the completion of discovery in one of the above-noted federal opt-out cases. The Company disputes the claims and intends to vigorously defend this matter. Antitrust Glumetza Antitrust Litigation Between August 2019 and February 2020, seven (7) putative antitrust class actions and three (3) non-class complaints were filed in the Northern District of California against the Company, Salix Pharmaceuticals, Ltd., Salix Pharmaceuticals, Inc., and Santarus, Inc. (among other defendants) (the “California Actions”). In February 2020, an eighth putative class action was filed in the Southern District of Florida; this action was transferred to the Northern District of California. Three (3) of the class actions were filed by plaintiffs seeking to represent a class of direct purchasers. The purported classes of direct purchasers filed a consolidated amended complaint on November 25, 2019. The five (5) class actions filed by end payer purchasers have all been voluntarily dismissed. The three (3) non-class complaints were filed by direct purchasers. These actions have been consolidated and coordinated in In re Glumetza Antitrust Litigation , Case No. 3:19-cv-05822-WHA. Both class and non-class direct purchaser plaintiffs seek damages under federal antitrust laws. The lawsuits allege that a 2012 settlement of a patent litigation regarding Glumetza ® delayed generic entry in exchange for an agreement not to launch an authorized generic of Glumetza ® or grant any other company a license to do so. The complaints allege that the settlement agreement resulted in higher prices for Glumetza ® and its generic equivalent both prior to and after generic entry. On April 29, 2020, the purported classes of direct purchasers filed their motion for class certification. Briefing on the motion is expected to conclude in June 2020. The Company and its affiliates named in these cases dispute the claims against them and intend to vigorously defend these matters. Other Antitrust Matters As referenced above during the three months ended March 31, 2020 , there have been no material updates or developments with respect to certain other proceedings or actions as described under “ Antitrust” in Note 21, “LEGAL PROCEEDINGS,” to the Company's Consolidated Financial Statements included in the Company's Annual Report on Form 10-K for the year ended December 31, 2019), filed with the SEC on February 19, 2020. This includes the following matter: Generic Pricing Antitrust Litigation Certain of the Company’s subsidiaries are defendants in a multidistrict antitrust litigation (“MDL”) entitled In re: Generic Pharmaceuticals Pricing Antitrust Litigation , pending in the United States District Court for the Eastern District of Pennsylvania. The lawsuits (which include claims by direct purchasers, end payers, indirect resellers and opt-outs) seek damages under federal and state antitrust laws, state consumer protection and unjust enrichment laws and allege that the Company’s subsidiaries entered into a conspiracy to fix, stabilize, and raise prices, rig bids and engage in market and customer allocation for generic pharmaceuticals. The Company disputes the claims against it and continues to defend itself vigorously. Intellectual Property Patent Litigation/Paragraph IV Matters From time to time, the Company (and/or certain of its affiliates) is also party to certain patent infringement proceedings in the United States and Canada, including as arising from claims filed by the Company (or that the Company anticipates filing within the required time periods) in connection with Notices of Paragraph IV Certification (in the United States) and Notices of Allegation (in Canada) received from third-party generic manufacturers respecting their pending applications for generic versions of certain products sold by or on behalf of the Company, including Relistor ® , Uceris ® , Xifaxan ® 200mg, Xifaxan ® 550mg, Plenvu ® , Bepreve ® , Bryhali ® and Jublia ® in the United States and Jublia ® in Canada, or other similar suits. On February 17, 2020, the Company and Alfasigma S.p.A. ("Alfasigma") received a Notice of Paragraph IV Certification from Norwich Pharmaceuticals Inc. (“Norwich”), in which Norwich asserted that the U.S. patents listed in the U.S. Food and Drug Administration's (the "FDA") Orange Book for the Company’s Xifaxan ® tablets, 550 mg, are either invalid, unenforceable and/or will not be infringed by the commercial manufacture, use or sale of Norwich’s generic rifaximin tablets, 550 mg, for which an Abbreviated New Drug Application (“ANDA”) has been filed by Norwich. The Company, through its subsidiaries Salix Pharmaceuticals, Inc. and Bausch Health Ireland Limited, holds the New Drug Application for Xifaxan ® and owns or exclusively licenses (from Alfasigma) these patents. On March 26, 2020, certain of the Company’s subsidiaries and Alfasigma filed suit against Norwich in the U.S. District Court for the District of Delaware (Case No. 20-cv-00430) pursuant to the Hatch-Waxman Act, alleging infringement by Norwich of one or more claims of the Xifaxan ® Patents, thereby triggering a 30-month stay of the approval of Norwich’s ANDA for rifaximin tablets, 550 mg. Xifaxan ® is protected by 23 patents covering the composition of matter and the use of Xifaxan ® listed in the FDA’s Approved Drug Products with Therapeutic Equivalence Evaluations, or the Orange Book. The Company remains confident in the strength of the Xifaxan ® patents and will continue to vigorously pursue this matter and defend its intellectual property. A similar suit was also filed against Sandoz, Inc. (“Sandoz”) in September 2019, alleging infringement by Sandoz of one or more claims of certain of these Xifaxan ® Patents by the commercial manufacture, use or sale of Sandoz’s generic rifaximin tablets, 550 mg, for which an ANDA had been filed. On May 6, 2020, the Company announced that an agreement had been reached with Sandoz that resolved this litigation. Under the terms of the agreement, the parties agreed to dismiss all litigation related to Xifaxan ® (rifaximin), Sandoz acknowledged the validity of the licensed patents for Xifaxan ® (rifaximin) 550 mg tablets and all intellectual property protecting Xifaxan ® (rifaximin) 550 mg tablets will remain intact and enforceable until expiry in October 2029. The agreement also grants Sandoz a non-exclusive license to the intellectual property relating to Xifaxan ® (rifaximin) 550 mg tablets in the United States beginning January 1, 2028 (or earlier under certain circumstances). Under the terms of the agreement, beginning January 1, 2028 (or earlier under certain circumstances), Sandoz will have the right to market a royalty-free generic version of Xifaxan ® (rifaximin) 550 mg tablets, should it receive approval from the FDA on its ANDA. Sandoz will be able to commence such marketing earlier if another generic rifaximin product is granted approval and such other generic rifaximin product begins to be sold or distributed in the United States before January 1, 2028. The Company will not make any financial payments or other transfers of value as part of this agreement with Sandoz. In addition, patents covering the Company's branded pharmaceutical products may be challenged in proceedings other than court proceedings, including inter partes review ("IPR") at the U.S. Patent & Trademark Office. The proceedings operate under different standards from district court proceedings, and are often completed within 18 months of institution. IPR challenges have been brought against patents covering the Company's branded pharmaceutical products. For example, following Acrux DDS’s IPR petition, the U.S. Patent and Trial Appeal Board, in May 2017, instituted inter partes review for an Orange Book-listed patent covering Jublia ® and, on June 6, 2018, issued a written determination invalidating such patent. An appeal of this decision was filed on August 7, 2018. On March 13, 2020, the Court of Appeals for the Federal Circuit reversed this decision and remanded the matter back to the PTAB for further proceedings. Jublia ® continues to be covered by eleven other Orange Book-listed patents owned by the Company and its licensor, which expire in the years 2028 through 2035. Product Liability As referenced above, during the three months ended March 31, 2020 , there have been no material updates or developments with respect to certain proceedings or actions as described under “ Product Liability” in Note 21, “LEGAL PROCEEDINGS,” to the Company's Consolidated Financial Statements included in the Company's Annual Report on Form 10-K for the year ended December 31, 2019, filed with the SEC on February 19, 2020. These matters include: Shower to Shower ® Products Liability Litigation Since 2016, the Company has been named in a number of product liability lawsuits involving the Shower to Shower ® body powder product acquired in September 2012 from Johnson & Johnson; due to dismissals, only twelve ( 12 ) of such product liability suits currently remain pending. Potential liability (including its attorneys’ fees and costs) arising out of these remaining suits is subject to full indemnification obligations of Johnson & Johnson owed to the Company, and legal fees and costs will be paid by Johnson & Johnson. Ten of these lawsuits filed by individual plaintiffs allege that the use of Shower to Shower ® caused the plaintiffs to develop ovarian cancer or mesothelioma. The allegations in these cases include failure to warn, design defect, manufacturing defect, negligence, gross negligence, breach of express and implied warranties, civil conspiracy concert in action, negligent misrepresentation, wrongful death, loss of consortium and/or punitive damages. The damages sought include compensatory damages, including medical expenses, lost wages or earning capacity, loss of consortium and/or compensation for pain and suffering, mental anguish anxiety and discomfort, physical impairment and loss of enjoyment of life. Plaintiffs also seek pre- and post-judgment interest, exemplary and punitive damages, and attorneys’ fees. Additionally, two proposed class actions have been filed in Canada against the Company and various Johnson & Johnson entities (one in the Supreme Court of British Columbia and one in the Superior Court of Quebec), on behalf of persons who have purchased or used Johnson & Johnson’s Baby Powder or Shower to Shower ® . The class actions allege the use of the product increases certain health risks (British Columbia) or negligence in failing to properly test, failing to warn of health risks, and failing to remove the products from the market in a timely manner (Quebec). The plaintiffs in these actions are seeking awards of general, special, compensatory and punitive damages. In accordance with the indemnification agreement, Johnson & Johnson will continue to vigorously defend the Company in each of the remaining actions that are not voluntarily dismissed or subject to a grant of summary judgment.

SEGMENT INFORMATION

SEGMENT INFORMATION	3 Months Ended
	Mar. 31, 2020
Segment Reporting [Abstract]
SEGMENT INFORMATION	SEGMENT INFORMATION Reportable Segments The Company’s Chief Executive Officer ("CEO"), who is the Company’s Chief Operating Decision Maker, manages the business through operating and reportable segments consistent with how the Company’s CEO: (i) assesses operating performance on a regular basis, (ii) makes resource allocation decisions and (iii) designates responsibilities of his direct reports. The Company operates in the following reportable segments: (i) Bausch + Lomb/International segment, (ii) Salix segment, (iii) Ortho Dermatologics segment and (iv) Diversified Products segment. The following is a brief description of the Company’s segments: • The Bausch + Lomb/International segment consists of: (i) sales in the U.S. of pharmaceutical products, OTC products and medical device products, primarily comprised of Bausch + Lomb products, with a focus on the Vision Care, Surgical, Consumer and Ophthalmology Rx products and (ii) with the exception of sales of Solta products, sales in Canada, Europe, Asia, Australia, Latin America, Africa and the Middle East of branded pharmaceutical products, branded generic pharmaceutical products, OTC products, medical device products and Bausch + Lomb products. • The Salix segment consists of sales in the U.S. of GI products. • The Ortho Dermatologics segment consists of: (i) sales in the U.S. of Ortho Dermatologics (dermatological) products and (ii) global sales of Solta medical aesthetic devices. • The Diversified Products segment consists of sales in the U.S. of: (i) pharmaceutical products in the areas of neurology and certain other therapeutic classes, (ii) generic products and (iii) dentistry products. Segment profit is based on operating income after the elimination of intercompany transactions. Certain costs, such as Amortization of intangible assets, Asset impairments, In-process research and development costs, Restructuring and integration costs, Acquisition-related contingent consideration costs and Other expense (income), net, are not included in the measure of segment profit, as management excludes these items in assessing segment financial performance. Corporate includes the finance, treasury, certain research and development programs, tax and legal operations of the Company’s businesses and incurs certain expenses, gains and losses related to the overall management of the Company, which are not allocated to the other business segments. In assessing segment performance and managing operations, management does not review segment assets. Furthermore, a portion of share-based compensation is considered a corporate cost, since the amount of such expense depends on company-wide performance rather than the operating performance of any single segment.

SIGNIFICANT ACCOUNTING POLICI_2

SIGNIFICANT ACCOUNTING POLICIES (Policies)	3 Months Ended
	Mar. 31, 2020
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation and Use of Estimates The accompanying unaudited 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 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, 2019 , filed with the U.S. Securities and Exchange Commission (the “SEC”) and the Canadian Securities Administrators on February 19, 2020 . The unaudited 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, 2019 , except for the new accounting guidance adopted during the period. The unaudited 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.
Use of Estimates	In preparing the unaudited Consolidated Financial Statements, management is required to make estimates and assumptions. This includes estimates and assumptions regarding the nature, timing and extent of the impacts that the COVID-19 pandemic will have on its operations and cash flows. 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 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	Principles of Consolidation The unaudited 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.
Adoption of New Accounting Guidance and Recently Issued Accounting Standards, Not Adopted as of March 31, 2020	Adoption of New Accounting Guidance In June 2016, the Financial Accounting Standards Board (“FASB”) issued guidance on the impairment of financial instruments requiring an impairment model based on expected losses rather than incurred losses. Under this guidance, an entity recognizes as an allowance its estimate of expected credit losses. The guidance was effective for the Company beginning January 1, 2020 and was applied using a modified retrospective approach through a cumulative-effect adjustment to accumulated deficit, which resulted in an increase to accumulated deficit of less than $1 million . The application of this guidance did not have a material effect on the Company's results of operations and cash flows. The Company estimates the current expected credit loss on its receivables based on various factors, including historical credit loss experience, customer credit worthiness, value of collaterals (if any), and any relevant current and reasonably supportable future economic factors. Additionally, the Company generally estimates the expected credit loss on a pool basis when customers are deemed to have similar risk characteristics. In August 2018, the FASB issued guidance modifying the disclosure requirements for fair value measurement. The guidance was effective for the Company beginning January 1, 2020. The application of this guidance did not have a material effect on the Company's disclosures. In March 2020, the FASB issued guidance providing optional expedients and exceptions for applying U.S. GAAP to contracts, hedging relationships, and other transactions that reference LIBOR or a reference rate that is expected to be discontinued as a result of reference rate reform. Optional expedients are provided for contract modification accounting within the areas of receivables, debt, leases, derivatives and hedging. The optional amendments are effective for all entities as of March 12, 2020, through December 31, 2022. During the three months ended March 31, 2020 , the Company has not entered into any contract modifications in which the optional expedients were applied. However, if prior to December 31, 2022 the Company enters into a contract modification in which the optional expedients are applied, the Company will evaluate the impact of adoption of this guidance on its financial position, results of operations and cash flows. Recently Issued Accounting Standards, Not Adopted as of March 31, 2020 In August 2018, the FASB issued guidance modifying the disclosure requirements for employers that sponsor defined benefit pension or other postretirement plans. The guidance is effective for annual periods ending after December 15, 2020, with early adoption permitted. The Company is evaluating the impact of adoption of this guidance on its disclosures. In December 2019, the FASB issued guidance simplifying the accounting for income taxes. The guidance is effective for annual periods ending after December 15, 2020, with early adoption permitted. The Company is evaluating the impact of adoption of this guidance on the Company's financial position, results of operations and cash flows.
Revenue Recognition	REVENUE RECOGNITION The Company’s revenues are primarily generated from product sales, principally in the therapeutic areas of eye-health, GI and dermatology, that consist of: (i) branded pharmaceuticals, (ii) generic and branded generic pharmaceuticals, (iii) OTC products and (iv) medical devices (contact lenses, intraocular lenses, ophthalmic surgical equipment and aesthetics devices). Other revenues include alliance and service revenue from the licensing and co-promotion of products and contract service revenue primarily in the areas of dermatology and topical medication. Contract service revenue is derived primarily from contract manufacturing for third parties and is not material. See Note 19, "SEGMENT INFORMATION" for the disaggregation of revenue which depicts how the nature, amount, timing and uncertainty of revenue and cash flows are affected by the economic factors of each category of customer contracts. Product Sales Provisions As is customary in the pharmaceutical industry, gross product sales are subject to a variety of deductions in arriving at reported net product sales. The transaction price for product sales is typically adjusted for variable consideration, which may be in the form of cash discounts, allowances, returns, rebates, chargebacks and distribution fees paid to customers. Provisions for variable consideration are established to reflect the Company’s best estimates of the amount of consideration to which it is entitled based on the terms of the contract. The amount of variable consideration included in the transaction price may be constrained, and is included in the net sales price only to the extent that it is probable that a significant reversal in the amount of the cumulative revenue recognized will not occur in a future period. Provisions for these deductions are recorded concurrently with the recognition of gross product sales revenue and include cash discounts and allowances, chargebacks, and distribution fees, which are paid to direct customers, as well as rebates and returns, which can be paid to direct and indirect customers. Returns provision balances and volume discounts to direct customers are included in Accrued and other current liabilities. All other provisions related to direct customers are included in Trade receivables, net, while provision balances related to indirect customers are included in Accrued and other current liabilities.
