Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation: The condensed consolidated financial statements and accompanying notes are prepared in accordance with United States (“U.S.”) generally accepted accounting principles (“GAAP”) for interim financial reporting and the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”) and therefore do not include all information and disclosures normally included in the annual consolidated financial statements. The condensed consolidated financial statements of McKesson include the financial statements of all wholly-owned subsidiaries and majority-owned or controlled companies. For those consolidated subsidiaries where the Company’s ownership is less than 100%, the portion of the net income or loss allocable to the noncontrolling interests is reported as “Net income attributable to noncontrolling interests” in the Condensed Consolidated Statements of Operations. All significant intercompany balances and transactions have been eliminated in consolidation, including the intercompany portion of transactions with equity method investees. Net income attributable to noncontrolling interests includes third-party equity interests in the Company’s consolidated entities, including ClarusONE Sourcing Services LLP, Vantage Oncology Holdings, LLC, and SCRI Oncology, LLC. Net income attributable to noncontrolling interests also included recurring compensation that the Company was obligated to pay to the noncontrolling shareholders of McKesson Europe AG (“McKesson Europe”) through the divestiture date. The Company’s noncontrolling interest in McKesson Europe was included in the divestiture of certain of the Company’s businesses in the European Union (“E.U.”) in October 2022, which is discussed further in Financial Note 2, “Business Acquisitions and Divestitures.” The Company considers itself to control an entity if it is the majority owner of or has voting control over such entity. The Company also assesses control through means other than voting rights and determines which business entity is the primary beneficiary of the variable interest entity (“VIE”). The Company consolidates VIEs when it is determined that it is the primary beneficiary of the VIE. Investments in business entities in which the Company does not have control, but instead has the ability to exercise significant influence over operating and financial policies, are accounted for using the equity method.
Fiscal Period	Fiscal Period: The Company’s fiscal year begins on April 1 and ends on March 31. Unless otherwise noted, all references to a particular year shall mean the Company’s fiscal year.
Reclassifications	Reclassifications: Certain prior period amounts have been reclassified to conform to the current year presentation.
Use of Estimates	Use of Estimates: The preparation of financial statements in conformity with U.S. GAAP requires the Company to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of these financial statements and income and expenses during the reporting period. Actual amounts could differ from those estimated amounts. In the opinion of management, the unaudited condensed consolidated financial statements include all normal recurring adjustments necessary for a fair presentation of the results of operations, financial position, and cash flows of McKesson for the interim periods presented.
Recently Adopted Accounting Pronouncements	Recently Adopted Accounting Pronouncements There were no accounting standards adopted by the Company during the nine months ended December 31, 2023. Recently Issued Accounting Pronouncements Not Yet Adopted In December 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. ASU 2023-09 improves the transparency of income tax disclosures by requiring, on an annual basis, consistent categories, and greater disaggregation of information in the rate reconciliation as well as income taxes paid disaggregated by jurisdiction. ASU 2023-09 is effective for the Company for fiscal years beginning after December 15, 2024. Early adoption is permitted. The amendments in this update should be applied prospectively, however, retrospective application is permitted. The Company is currently evaluating the impact that this guidance will have on its disclosures. In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures. ASU 2023-07 expands reportable segment disclosures by requiring disclosure, on an annual and interim basis, of significant segment expenses that are regularly provided to the chief operating decision maker (“CODM”) and included within each reported measure of segment profit or loss as well as an amount and description of other segment items. ASU 2023-07 also requires interim disclosures of a reportable segment’s profit or loss and assets, disclosure of the title and position of the CODM, and an explanation of how the CODM uses the reported measure of segment profit or loss in assessing performance and allocating resources. ASU 2023-07 is effective for the Company for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted. The amendments in this update are required to be applied retrospectively to all prior periods presented in the financial statements. The Company is currently evaluating the impact that this guidance will have on its disclosures. In June 2022, the FASB issued ASU 2022-03, Fair Value Measurement (Topic 820): Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions, which clarifies the guidance when measuring the fair value of an equity security subject to contractual restrictions that prohibit the sale of such equity security and requires additional disclosure requirements. ASU 2022-03 is effective for the Company for fiscal years beginning after December 15, 2023, and interim periods within those fiscal years. Early adoption is permitted. The amendments in this update are required to be applied prospectively. The Company does not anticipate that this guidance will have a material impact on its consolidated financial statements or related disclosures
Fair Value	The Company measures certain assets and liabilities at fair value in accordance with ASC Topic 820, Fair Value Measurements and Disclosures. The fair value hierarchy consists of three levels of inputs that may be used to measure fair value as follows: Level 1 - quoted prices in active markets for identical assets or liabilities. Level 2 - significant other observable market-based inputs. Level 3 - significant unobservable inputs for which little or no market data exists and requires considerable assumptions that are significant to the fair value measurement. Assets and Liabilities Measured at Fair Value on a Recurring Basis Cash and cash equivalents at December 31, 2023 and March 31, 2023 included investments in money market funds of $432 million and $1.4 billion, respectively, which are reported at fair value. The fair value of money market funds was determined using quoted prices for identical investments in active markets, which are considered to be Level 1 inputs under the fair value measurements and disclosure guidance. The carrying value of all other cash equivalents approximates their fair value due to their relatively short-term nature. Fair values of the Company’s interest rate swaps, cross-currency swaps, and foreign currency forward contracts were determined using observable inputs from available market information, including quoted interest rates, foreign currency exchange rates, and other observable inputs from available market information. These inputs are considered Level 2 under the fair value measurements and disclosure guidance, and may not be representative of actual values that could have been realized or that will be realized in the future. Refer to Financial Note 8, “Hedging Activities,” for fair values and other information on the Company’s derivatives. The Company holds investments in equity securities of U.S. growth stage companies that address both current and emerging business challenges in the healthcare industry and which had a carrying value of $213 million and $237 million at December 31, 2023 and March 31, 2023, respectively. These investments primarily consist of equity securities without readily determinable fair values and are included in “Other non-current assets” in the Condensed Consolidated Balance Sheets. The carrying value of publicly-traded investments, which was not material for the periods presented, was determined using quoted prices for identical investments in active markets and are considered to be Level 1 inputs. The net realized and unrealized gains and losses as well as impairment charges related to these investments are included within “Other income, net” in the Condensed Consolidated Statements of Operations and were not material for the three and nine months ended December 31, 2023 and 2022. Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis In addition to assets and liabilities that are measured at fair value on a recurring basis, the Company’s assets and liabilities are also subject to nonrecurring fair value measurements. Generally, assets are recorded at fair value on a nonrecurring basis as a result of impairment charges or as a result of charges to remeasure assets classified as held for sale to fair value less costs to sell. The aforementioned investments in equity securities of U.S. growth stage companies include the carrying value of investments without readily determinable fair values, which were determined using a measurement alternative and are recorded at cost less impairment, plus or minus any changes in observable price from orderly transactions of the same or similar security of the same issuer. These inputs related to changes in observable price are considered Level 2 under the fair value measurements and disclosure guidance and may not be representative of actual values that could have been realized or that will be realized in the future. Inputs related to impairments of investments are generally considered Level 3 fair value measurements due to their inherently unobservable nature based on significant assumptions by management and use of company-specific information. Goodwill Fair value assessments of the reporting unit and the reporting unit's net assets, which are performed for goodwill impairment tests, are considered a Level 3 measurement due to the significance of unobservable inputs developed using company-specific information. The Company considered a market approach as well as an income approach using a discounted cash flow (“DCF”) model to determine the fair value of each reporting unit. Long-lived Assets The Company utilizes multiple approaches, including the DCF model and market approaches, for estimating the fair value of intangible assets. The future cash flows used in the analysis are based on internal cash flow projections from its long-range plans and include significant assumptions by management. Accordingly, the fair value assessment of long-lived assets is considered a Level 3 fair value measurement. The Company measures certain long-lived and intangible assets at fair value on a nonrecurring basis when events occur that indicate an asset group may not be recoverable. If the carrying amount of an asset group is not recoverable, an impairment charge is recorded to reduce the carrying amount by the excess over its fair value.
Hedging Activities	Net Investment Hedges The Company uses cross-currency swaps to hedge portions of the Company’s net investments denominated in Canadian dollars against the effect of exchange rate fluctuations on the translation of foreign currency balances to the U.S. dollar. The changes in the fair value of these derivatives attributable to the changes in spot currency exchange rates and differences between spot and forward interest rates are recorded in accumulated other comprehensive loss and offset foreign currency translation gains and losses recorded on the Company’s net investments denominated in Canadian dollars. To the extent cross-currency swaps designated as hedges are ineffective, changes in carrying value attributable to the change in spot rates are recorded in earnings. Fair Value Hedges The Company uses cross-currency swaps to hedge the changes in the fair value of its foreign currency notes resulting from changes in benchmark interest rates and foreign currency exchange rates. The Company also uses interest rate swaps to hedge the changes in the fair value of its U.S. dollar notes resulting from changes in benchmark interest rates. The changes in the fair value of these derivatives and the offsetting changes in the fair value of the hedged notes are recorded in earnings. Gains from the changes in the Company’s fair value hedges recorded in earnings were largely offset by the losses recorded in earnings on the hedged item. For components excluded from the assessment of hedge effectiveness, the initial value of the excluded component is recognized in accumulated other comprehensive loss and then released into earnings over the life of the hedging instrument. The difference between the change in the fair value of the excluded component and the amount amortized into earnings during the period is recorded in other comprehensive income. Cash Flow Hedges From time to time, the Company enters into cross-currency swaps to hedge intercompany loans denominated in non-functional currencies to reduce the income statement effects arising from fluctuations in foreign currency exchange rates. The Company also enters into forward contracts to hedge the variability of future benchmark interest rates on any planned bond issuances and to offset the potential income statement effects from obligations denominated in non-functional currencies. The effective portion of changes in the fair value of these hedges is recorded in accumulated other comprehensive loss and reclassified into earnings in the same period in which the hedged transaction affects earnings. Changes in fair values representing hedge ineffectiveness are recognized in current earnings. Gains or losses reclassified from accumulated other comprehensive loss and recorded in “Selling, distribution, general, and administrative expenses” in the Condensed Consolidated Statements of Operations were not material for the three and nine months ended December 31, 2023 and 2022.
Commitments and Contingencies	In addition to commitments and obligations incurred in the ordinary course of business, the Company is subject to a variety of claims and legal proceedings, including claims from customers and vendors, pending and potential legal actions for damages, governmental investigations, and other matters. The Company and its affiliates are parties to the legal claims and proceedings described below and in Financial Note 17 to the Company’s 2023 Annual Report, Financial Note 10 to the Company’s 10-Q filing for the quarterly period ended June 30, 2023, and Financial Note 10 to the Company’s 10-Q filing for the quarterly period ended September 30, 2023, which disclosure is incorporated in this footnote by this reference. The Company is vigorously defending itself against those claims and in those proceedings. Significant developments in those matters are described below. If the Company is unsuccessful in defending, or if it determines to settle, any of these matters, it may be required to pay substantial sums, be subject to injunction and/or be forced to change how it operates its business, which could have a material adverse impact on its financial position or results of operations. Unless otherwise stated, the Company is unable to reasonably estimate the loss or a range of possible loss for the matters described below. Often, the Company is unable to determine that a loss is probable, or to reasonably estimate the amount of loss or a range of loss, for a claim because of the limited information available and the potential effects of future events and decisions by third parties, such as courts and regulators, that will determine the ultimate resolution of the claim. Many of the matters described are at preliminary stages, raise novel theories of liability, or seek an indeterminate amount of damages. It is not uncommon for claims to remain unresolved over many years. The Company reviews loss contingencies at least quarterly to determine whether the likelihood of loss has changed and whether it can make a reasonable estimate of the loss or range of loss. When the Company determines that a loss from a claim is probable and reasonably estimable, it records a liability for an estimated amount. The Company also provides disclosure when it is reasonably possible that a loss may be incurred or when it is reasonably possible that the amount of a loss will exceed its recorded liability. Amounts included within “Claims and litigation charges, net” in the Condensed Consolidated Statements of Operations consist of estimated loss contingencies related to opioid-related litigation matters, as well as any applicable income items or credit adjustments due to subsequent changes in estimates.

Significant Accounting Policies (Policies)

9 Months Ended

Dec. 31, 2023

Basis of Presentation: The condensed consolidated financial statements and accompanying notes are prepared in accordance with United States (“U.S.”) generally accepted accounting principles (“GAAP”) for interim financial reporting and the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”) and therefore do not include all information and disclosures normally included in the annual consolidated financial statements.

The condensed consolidated financial statements of McKesson include the financial statements of all wholly-owned subsidiaries and majority-owned or controlled companies. For those consolidated subsidiaries where the Company’s ownership is less than 100%, the portion of the net income or loss allocable to the noncontrolling interests is reported as “Net income attributable to noncontrolling interests” in the Condensed Consolidated Statements of Operations. All significant intercompany balances and transactions have been eliminated in consolidation, including the intercompany portion of transactions with equity method investees.

Net income attributable to noncontrolling interests includes third-party equity interests in the Company’s consolidated entities, including ClarusONE Sourcing Services LLP, Vantage Oncology Holdings, LLC, and SCRI Oncology, LLC. Net income attributable to noncontrolling interests also included recurring compensation that the Company was obligated to pay to the noncontrolling shareholders of McKesson Europe AG (“McKesson Europe”) through the divestiture date. The Company’s noncontrolling interest in McKesson Europe was included in the divestiture of certain of the Company’s businesses in the European Union (“E.U.”) in October 2022, which is discussed further in Financial Note 2, “Business Acquisitions and Divestitures.”

The Company considers itself to control an entity if it is the majority owner of or has voting control over such entity. The Company also assesses control through means other than voting rights and determines which business entity is the primary beneficiary of the variable interest entity (“VIE”). The Company consolidates VIEs when it is determined that it is the primary beneficiary of the VIE. Investments in business entities in which the Company does not have control, but instead has the ability to exercise significant influence over operating and financial policies, are accounted for using the equity method.

Fiscal Period

Fiscal Period: The Company’s fiscal year begins on April 1 and ends on March 31. Unless otherwise noted, all references to a particular year shall mean the Company’s fiscal year.

Reclassifications

Reclassifications: Certain prior period amounts have been reclassified to conform to the current year presentation.

Use of Estimates

Use of Estimates: The preparation of financial statements in conformity with U.S. GAAP requires the Company to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of these financial statements and income and expenses during the reporting period. Actual amounts could differ from those estimated amounts. In the opinion of management, the unaudited condensed consolidated financial statements include all normal recurring adjustments necessary for a fair presentation of the results of operations, financial position, and cash flows of McKesson for the interim periods presented.

Recently Adopted Accounting Pronouncements

There were no accounting standards adopted by the Company during the nine months ended December 31, 2023.

Recently Issued Accounting Pronouncements Not Yet Adopted

In December 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. ASU 2023-09 improves the transparency of income tax disclosures by requiring, on an annual basis, consistent categories, and greater disaggregation of information in the rate reconciliation as well as income taxes paid disaggregated by jurisdiction. ASU 2023-09 is effective for the Company for fiscal years beginning after December 15, 2024. Early adoption is permitted. The amendments in this update should be applied prospectively, however, retrospective application is permitted. The Company is currently evaluating the impact that this guidance will have on its disclosures.

In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures. ASU 2023-07 expands reportable segment disclosures by requiring disclosure, on an annual and interim basis, of significant segment expenses that are regularly provided to the chief operating decision maker (“CODM”) and included within each reported measure of segment profit or loss as well as an amount and description of other segment items. ASU 2023-07 also requires interim disclosures of a reportable segment’s profit or loss and assets, disclosure of the title and position of the CODM, and an explanation of how the CODM uses the reported measure of segment profit or loss in assessing performance and allocating resources. ASU 2023-07 is effective for the Company for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted. The amendments in this update are required to be applied retrospectively to all prior periods presented in the financial statements. The Company is currently evaluating the impact that this guidance will have on its disclosures.

In June 2022, the FASB issued ASU 2022-03, Fair Value Measurement (Topic 820): Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions, which clarifies the guidance when measuring the fair value of an equity security subject to contractual restrictions that prohibit the sale of such equity security and requires additional disclosure requirements. ASU 2022-03 is effective for the Company for fiscal years beginning after December 15, 2023, and interim periods within those fiscal years. Early adoption is permitted. The amendments in this update are required to be applied prospectively. The Company does not anticipate that this guidance will have a material impact on its consolidated financial statements or related disclosures

Fair Value

The Company measures certain assets and liabilities at fair value in accordance with ASC Topic 820, Fair Value Measurements and Disclosures. The fair value hierarchy consists of three levels of inputs that may be used to measure fair value as follows:

Level 1 - quoted prices in active markets for identical assets or liabilities.

Level 2 - significant other observable market-based inputs.

Level 3 - significant unobservable inputs for which little or no market data exists and requires considerable assumptions that are significant to the fair value measurement.

Assets and Liabilities Measured at Fair Value on a Recurring Basis

Cash and cash equivalents at December 31, 2023 and March 31, 2023 included investments in money market funds of $432 million and $1.4 billion, respectively, which are reported at fair value. The fair value of money market funds was determined using quoted prices for identical investments in active markets, which are considered to be Level 1 inputs under the fair value measurements and disclosure guidance. The carrying value of all other cash equivalents approximates their fair value due to their relatively short-term nature.

Fair values of the Company’s interest rate swaps, cross-currency swaps, and foreign currency forward contracts were determined using observable inputs from available market information, including quoted interest rates, foreign currency exchange rates, and other observable inputs from available market information. These inputs are considered Level 2 under the fair value measurements and disclosure guidance, and may not be representative of actual values that could have been realized or that will be realized in the future. Refer to Financial Note 8, “Hedging Activities,” for fair values and other information on the Company’s derivatives.

The Company holds investments in equity securities of U.S. growth stage companies that address both current and emerging business challenges in the healthcare industry and which had a carrying value of $213 million and $237 million at December 31, 2023 and March 31, 2023, respectively. These investments primarily consist of equity securities without readily determinable fair values and are included in “Other non-current assets” in the Condensed Consolidated Balance Sheets. The carrying value of publicly-traded investments, which was not material for the periods presented, was determined using quoted prices for identical investments in active markets and are considered to be Level 1 inputs. The net realized and unrealized gains and losses as well as impairment charges related to these investments are included within “Other income, net” in the Condensed Consolidated Statements of Operations and were not material for the three and nine months ended December 31, 2023 and 2022.

Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis

In addition to assets and liabilities that are measured at fair value on a recurring basis, the Company’s assets and liabilities are also subject to nonrecurring fair value measurements. Generally, assets are recorded at fair value on a nonrecurring basis as a result of impairment charges or as a result of charges to remeasure assets classified as held for sale to fair value less costs to sell.

The aforementioned investments in equity securities of U.S. growth stage companies include the carrying value of investments without readily determinable fair values, which were determined using a measurement alternative and are recorded at cost less impairment, plus or minus any changes in observable price from orderly transactions of the same or similar security of the same issuer. These inputs related to changes in observable price are considered Level 2 under the fair value measurements and disclosure guidance and may not be representative of actual values that could have been realized or that will be realized in the future. Inputs related to impairments of investments are generally considered Level 3 fair value measurements due to their inherently unobservable nature based on significant assumptions by management and use of company-specific information.

Goodwill

Fair value assessments of the reporting unit and the reporting unit's net assets, which are performed for goodwill impairment tests, are considered a Level 3 measurement due to the significance of unobservable inputs developed using company-specific information. The Company considered a market approach as well as an income approach using a discounted cash flow (“DCF”) model to determine the fair value of each reporting unit.

Long-lived Assets

The Company utilizes multiple approaches, including the DCF model and market approaches, for estimating the fair value of intangible assets. The future cash flows used in the analysis are based on internal cash flow projections from its long-range plans and include significant assumptions by management. Accordingly, the fair value assessment of long-lived assets is considered a Level 3 fair value measurement.

The Company measures certain long-lived and intangible assets at fair value on a nonrecurring basis when events occur that indicate an asset group may not be recoverable. If the carrying amount of an asset group is not recoverable, an impairment charge is recorded to reduce the carrying amount by the excess over its fair value.

Hedging Activities

Net Investment Hedges

The Company uses cross-currency swaps to hedge portions of the Company’s net investments denominated in Canadian dollars against the effect of exchange rate fluctuations on the translation of foreign currency balances to the U.S. dollar. The changes in the fair value of these derivatives attributable to the changes in spot currency exchange rates and differences between spot and forward interest rates are recorded in accumulated other comprehensive loss and offset foreign currency translation gains and losses recorded on the Company’s net investments denominated in Canadian dollars. To the extent cross-currency swaps designated as hedges are ineffective, changes in carrying value attributable to the change in spot rates are recorded in earnings.

Fair Value Hedges

The Company uses cross-currency swaps to hedge the changes in the fair value of its foreign currency notes resulting from changes in benchmark interest rates and foreign currency exchange rates. The Company also uses interest rate swaps to hedge the changes in the fair value of its U.S. dollar notes resulting from changes in benchmark interest rates. The changes in the fair value of these derivatives and the offsetting changes in the fair value of the hedged notes are recorded in earnings. Gains from the changes in the Company’s fair value hedges recorded in earnings were largely offset by the losses recorded in earnings on the hedged item. For components excluded from the assessment of hedge effectiveness, the initial value of the excluded component is recognized in accumulated other comprehensive loss and then released into earnings over the life of the hedging instrument. The difference between the change in the fair value of the excluded component and the amount amortized into earnings during the period is recorded in other comprehensive income.

Cash Flow Hedges

From time to time, the Company enters into cross-currency swaps to hedge intercompany loans denominated in non-functional currencies to reduce the income statement effects arising from fluctuations in foreign currency exchange rates. The Company also enters into forward contracts to hedge the variability of future benchmark interest rates on any planned bond issuances and to offset the potential income statement effects from obligations denominated in non-functional currencies. The effective portion of changes in the fair value of these hedges is recorded in accumulated other comprehensive loss and reclassified into earnings in the same period in which the hedged transaction affects earnings. Changes in fair values representing hedge ineffectiveness are recognized in current earnings. Gains or losses reclassified from accumulated other comprehensive loss and recorded in “Selling, distribution, general, and administrative expenses” in the Condensed Consolidated Statements of Operations were not material for the three and nine months ended December 31, 2023 and 2022.

Commitments and Contingencies

In addition to commitments and obligations incurred in the ordinary course of business, the Company is subject to a variety of claims and legal proceedings, including claims from customers and vendors, pending and potential legal actions for damages, governmental investigations, and other matters. The Company and its affiliates are parties to the legal claims and proceedings described below and in Financial Note 17 to the Company’s 2023 Annual Report, Financial Note 10 to the Company’s 10-Q filing for the quarterly period ended June 30, 2023, and Financial Note 10 to the Company’s 10-Q filing for the quarterly period ended September 30, 2023, which disclosure is incorporated in this footnote by this reference. The Company is vigorously defending itself against those claims and in those proceedings. Significant developments in those matters are described below. If the Company is unsuccessful in defending, or if it determines to settle, any of these matters, it may be required to pay substantial sums, be subject to injunction and/or be forced to change how it operates its business, which could have a material adverse impact on its financial position or results of operations.

Unless otherwise stated, the Company is unable to reasonably estimate the loss or a range of possible loss for the matters described below. Often, the Company is unable to determine that a loss is probable, or to reasonably estimate the amount of loss or a range of loss, for a claim because of the limited information available and the potential effects of future events and decisions by third parties, such as courts and regulators, that will determine the ultimate resolution of the claim. Many of the matters described are at preliminary stages, raise novel theories of liability, or seek an indeterminate amount of damages. It is not uncommon for claims to remain unresolved over many years. The Company reviews loss contingencies at least quarterly to determine whether the likelihood of loss has changed and whether it can make a reasonable estimate of the loss or range of loss. When the Company determines that a loss from a claim is probable and reasonably estimable, it records a liability for an estimated amount. The Company also provides disclosure when it is reasonably possible that a loss may be incurred or when it is reasonably possible that the amount of a loss will exceed its recorded liability. Amounts included within “Claims and litigation charges, net” in the Condensed Consolidated Statements of Operations consist of estimated loss contingencies related to opioid-related litigation matters, as well as any applicable income items or credit adjustments due to subsequent changes in estimates.
