In connection with the completion of this evaluation in the first quarter of 2019, our operating structure is realigned, and we will report our financial results in three reportable segments on a retrospective basis commencing in the first quarter of 2019: U.S. Pharmaceutical and Specialty Solutions, European Pharmaceutical Solutions and Medical-Surgical Solutions. All remaining operating segments and business activities that are not significant enough to require separate reportable segment disclosure will be included in Other. Other primarily consists of McKesson Canada, McKesson Prescription Technology Solutions and our equity method investment in Change Healthcare. The segment changes will reflect how our CODM allocates resources and assesses performance commencing in the first quarter of 2019. Refer to Financial Note 28, “Segments of Business” to the consolidated financial statements appearing in this Annual Report on Form 10-K for additional information.
Restructuring, Business Combinations, Investments, Discontinued Operations and Divestitures
We have undertaken additional strategic initiatives in recent years designed to further focus on our core healthcare businesses and enhance our competitive position. We expect to continue to undertake such strategic initiatives in the future. These initiatives are detailed in Financial Notes 2, 3, 4, and 5, 6“Investment in Change Healthcare Joint Venture,” “Held for Sale,” “Restructuring, Impairment, and 7, “Healthcare Technology Net Asset Exchange,Related Charges,“Divestitures,”and “Business Combinations”Acquisitions and “Discontinued Operations”Divestitures,” to the consolidated financial statements appearing in this Annual Report on Form 10-K.
Competition
Our two reportable segments, Distribution Solutions and Technology Solutions,We face highly competitive global environments withenvironments. Additionally, in recent years the healthcare industry has been subject to increasing consolidation. In the pharmaceutical distribution environment in which our U.S. Pharmaceutical and International segments operate, we face strong competition from international, national, regional and local full-line, short-line and specialty distributors, service merchandisers, self-warehousing chain drug stores, manufacturers engaged in direct distribution, third-party logistics companies, and large payer organizations. In addition, these segmentsOur retail businesses, which primarily operate in our International segment, face competition from various global, national, regional, and local global retailers, including chain and independent pharmacies. We consider our largest competitors in distribution, wholesaling, and logistics to be AmerisourceBergen Corporation and Cardinal Health, Inc.
Our Medical-Surgical Solutions segment provides medical-surgical supply distribution, logistics, and other services to healthcare providers, including physician offices, surgery centers, nursing homes, hospital reference labs, home health care agencies, and alternative health sites with competition from a wide range of national and regional medical supply and equipment distributors throughout the U.S.
Our RxTS business experiences substantial competition from many companies, including other software services firms, consulting firms, shared service vendors, and internet-based companies with technology applicable to the healthcare industry. Competition in this business varies in size from large to small companies, in geographical coverage, and in scope and breadth of products and services offered.
In addition, we compete with other service providers, and from pharmaceutical and other healthcare manufacturers, as well as other potential customers of the segment,our businesses, which may from time-to-timetime to time decide to develop, for their own internal needs, supply management capabilities that wouldmight otherwise be provided by the segment.our businesses. We believe that our scale and diversity of product and service offerings are our primary competitive advantages. In all areas, key competitive factors include price, quality of service, breadth of product lines, innovation and, in some cases, convenience to the customer.

Investment in Employees: To support employee growth, we provide regular feedback and training, and work to create and maintain inclusive work settings where everyone can bring their authentic self to work and feel welcomed and appreciated, and where their perspectives are sought out, heard, and considered. Through training, we encourage leaders to embrace diverse perspectives and lead inclusively. Employee development programs include training, coaching, and 360-degree assessments, which can support the careers of future leaders and their teams. We offer financial assistance programs for higher education opportunities that support employees’ career growth at the company. To provide compensation that is focused on attracting and retaining talent with the skills and experience necessary for a specific role, our compensation program is built on a set of quantifiable factors defined by our guiding principles of internal fairness, market competitiveness, and pay for performance. We operate in several countries and our benefits offerings vary accordingly. We offer health and wellness benefits to advance the physical, mental, and social well-being of our people, savings programs to help prepare them for retirement, and flexible work arrangements, among other benefits offerings, when possible. In response to the COVID-19 pandemic, we offered extended medical benefits covering COVID-19 related visits, treatment and testing, expanded telehealth options, emergency paid time off (“PTO”), and a platform for employees to donate their regular PTO to co-workers who were more impacted by COVID-19. We also seek employee feedback through an annual employee opinion survey, which assesses our employees’ levels of engagement, commitment, and overall satisfaction using industry benchmarks, and we then design action plans to improve those metrics.
Health and Safety: Our security and safety departments employ systems designed to continually monitor our facilities and work environment to help identify and prevent or mitigate any potential risks. This includes having procedures in place and investing in equipment for both physical and electronic security. We routinely assess facilities to monitor closely adherence to established security and safety standards. If we identify a vulnerability, it is documented, and the facility prepares an action plan. Our employees receive specialized training related to their role, work setting, and equipment used in their work environment. As our processes evolve, we update relevant safety training modules, which may include new employee training programs. In response to the COVID-19 pandemic, our priority has been, and continues to be, protecting the health and safety of our employees. The various responses we put in place to mitigate the impact of COVID-19 on our business operations, including telecommuting and work-from-home policies, restricted travel, and enhanced safety measures, are intended to limit employee exposure to the virus that causes COVID-19 as they perform their jobs while also providing employee support programs and a sense of belonging. For additional information on our response to COVID-19 in the workplace, refer to the COVID-19 section of “Trends and Uncertainties” in “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in Item 7 of Part II included in this Annual Report on Form 10-K.
Government Regulation
McKesson, generally and in many of the highly regulated industries in which it operates, is subject to oversight by various federal, state, and local governmental entities. Failure to comply with laws, regulations, and guidance promulgated by those entities could have a material adverse impact to the Company’s business operations, reputation, results of operations, and financial position.
Controlled Substances: We are subject to the operating and security standards of the Drug Enforcement Administration (“DEA”), the U.S. Food and Drug Administration (“FDA”), various state boards of pharmacy, state health departments, HHS, the Centers for Medicare & Medicaid Services (“CMS”), and other comparable agencies. We have received monetary penalties and/or licensing sanctions pursuant to these requirements and future allegations of noncompliance could result in an inability to obtain, maintain or renew permits, licenses or other regulatory approvals needed for the operation of our businesses.

McKESSON CORPORATION
Additionally, the Company is a defendant in approximately 3,200 cases alleging claims related to the distribution of controlled substances (opioids), as described in Financial Note 19, “Commitments and Contingent Liabilities,” to the consolidated financial statements in this Annual Report on Form 10-K. The plaintiffs in those cases include governmental entities (such as states, provinces, counties and municipalities) as well as businesses, groups and individuals. As a result of ongoing, advanced discussions with state attorneys general and plaintiffs’ representatives regarding a framework to resolve the claims of governmental entities, and our assessment of certain other opioid-related claims, we have reached a stage at which a broad settlement of opioid claims by governmental entities is probable and recorded a charge of $8.1 billion for the year ended March 31, 2021 within “Claims and litigation charges, net” in our Consolidated Statement of Operations in this Annual Report on Form 10-K. Because of the many uncertainties associated with any potential settlement arrangement or other resolution of opioid-related litigation, including the uncertainty of the scope of participation by plaintiffs in any potential settlement, we are not able to reasonably estimate the upper or lower ends of the range of ultimate possible loss for all opioid-related litigation matters. The adverse outcome of legal proceedings might also involve significant expense, management time and distraction, and risk of loss that can be difficult to predict or quantify. In addition to this litigation, legislative or regulatory measures related to the distribution of controlled substances such as prescription opioids could affect our business in ways that we may not be able to predict. For example, some states have passed legislation that could require us to pay taxes or assessments on the distribution of opioid medications in those states and other states have considered similar legislation.
Government Contracts: Our contracts with government entities are subject to unique compliance risks and typically are subject to procurement laws that include socio-economic, employment practices, environmental protection, recordkeeping and accounting, and other requirements. We are subject to government audits, investigations and oversight proceedings. Government agencies routinely review and audit government contractors to determine whether they are complying with contractual and legal requirements. If we fail to comply with these requirements, or we fail an audit, we may be subject to various sanctions such as monetary damages, criminal and civil penalties, termination of contracts and suspension or debarment from government contract work. These requirements complicate our business and increase our compliance burden and material non-compliance could harm our reputation.
Local, state, and federal governments continue to strengthen their position and scrutiny over practices involving or allegedly involving fraud, waste, and abuse affecting Medicare, Medicaid, other government healthcare programs, and government contracts. Our relationships with pharmaceutical and medical surgical product manufacturers and healthcare providers, as well as our provision of products and services to government entities, subject our business to laws, regulation, and government guidance on fraud and abuse. Many of these laws are vague or indefinite and have not been interpreted by the courts and, as such, may be interpreted or applied by a prosecutorial, regulatory, or judicial authority in a manner that could require us to make changes in our operations. Failure to comply with applicable laws, regulations, and government guidance, including but not limited to those involving the regulation of controlled substances, the federal Anti-Kickback Statute, and others, could subject us to federal or state government investigations or qui tam actions, and to liability for damages and civil and criminal penalties, including the loss of licenses or our ability to participate in Medicare, Medicaid and other federal and state healthcare programs, or pursue government contracts.
Healthcare Regulation: In the U.S., the Patient Protection and Affordable Care Act (“ACA”) significantly expanded health insurance coverage to uninsured Americans and changed the way healthcare is financed by both governmental and private payers. There are also further efforts to broaden healthcare coverage. U.S. lawmakers also have explored proposals to reduce drug prices, including requiring price transparency and drug importation measures. Provincial governments in Canada that provide partial funding for the purchase of pharmaceuticals and independently regulate the sale and reimbursement of drugs have sought to reduce the costs of publicly funded health programs. For example, provincial governments have taken steps to reduce consumer prices for generic pharmaceuticals and, in some provinces, change professional allowances paid to pharmacists by generic manufacturers. Many European governments provide or subsidize healthcare to consumers and regulate pharmaceutical prices, patient eligibility and reimbursement levels in order to control government healthcare system costs. Some European governments have implemented or are considering austerity measures to reduce healthcare spending. These measures exert pressure on the pricing and reimbursement timelines for pharmaceuticals and may cause our customers to purchase fewer of our products and services or influence us to reduce prices. There is substantial uncertainty about the likelihood, timing and results of these health reform efforts.

Additionally, there have been increasing efforts by governments to regulate the pharmaceutical distribution system in order to prevent the introduction of counterfeit, adulterated and/or mislabeled drugs into the pharmaceutical distribution system, otherwise known as pedigree tracking. For example, the U.S. Drug Quality and Security Act of 2013 (“DQSA”) requires us to participate in a federal prescription drug track and trace system that preempts state drug pedigree requirements, and the U.S. Food and Drug Administration Amendments Act of 2007 requires the FDA to establish standards and identify and validate effective technologies, such as track and trace or authentication technologies, to secure the pharmaceutical supply chain against counterfeit drugs. We also have record-keeping and other obligations under the E.U. Falsified Medicines Directive. Pedigree tracking laws such as these increase our compliance burden and our pharmaceutical distribution costs.
Data Security and Privacy: We are subject to a variety of privacy and data protection laws that change frequently and have requirements that vary from jurisdiction to jurisdiction. For example, under the Health Insurance Portability and Accountability Act of 1996 (“HIPAA”) we must maintain administrative, physical and technological safeguards to protect individually identifiable health information (“protected health information”) and ensure the confidentiality, integrity, and availability of electronic protected health information. We are subject to significant compliance obligations under privacy laws such as the General Data Protection Regulation (“GDPR”) in the European Union, the Personal Information Protection and Electronic Documents Act (“PIPEDA”) in Canada, and the California Consumer Protection Act (“CCPA”). Some privacy laws prohibit the transfer of personal information to certain other jurisdictions. We are subject to privacy and data protection compliance audits or investigations by various government agencies. Failure to comply with these laws subjects us to potential regulatory enforcement activity, fines, private litigation including class actions, and other costs. We also have contractual obligations to customers that might be breached if we fail to comply with privacy laws. Our efforts to comply with privacy laws complicate our operations and add to our compliance costs.
We and our external service providers use technology and systems to perform our business operations, such as the secure electronic transmission, processing, storage and hosting of sensitive information, including protected health information and other types of personal information, confidential financial information, proprietary information, and other sensitive information relating to our customers, company and workforce. Despite physical, technical, and administrative security measures that we implement in order to, among other things, address regulatory requirements, our technology systems and operations may continue to be subject to cybersecurity incidents. The risk of cybersecurity incidents may be increased due to a variety of factors, both internal and external. A cybersecurity incident might involve a material data breach or other material impact to the integrity and operations of the technology systems and operations, which might result in litigation or regulatory action.
Environmental Regulation: We are subject to many environmental and hazardous materials regulations, including those relating to radiation-emitting equipment operated at U.S. Oncology Network practices. Additionally, our operations are subject to regulations under various federal, state, local and foreign laws concerning the environment, including laws addressing the discharge of pollutants into the air and water, the management and disposal of hazardous substances and wastes, and the cleanup of contaminated sites, as discussed in more detail below. We could incur substantial costs, including cleanup costs, fines and civil or criminal sanctions, and third-party damage or personal injury claims, if in the future we were to violate or become liable under environmental laws. We are committed to maintaining compliance with all environmental laws applicable to our operations, products and services and to reducing our environmental impact across all aspects of our business. We meet this commitment through an environmental strategy and sustainability program.
We sold our chemical distribution operations in 1987 and retained responsibility for certain environmental obligations. Agreements with the Environmental Protection Agency and certain states may require environmental assessments and cleanups at several closed sites. These matters are described further in Financial Note 19, “Commitments and Contingent Liabilities,” to the consolidated financial statements appearing in this Annual Report on Form 10-K.
The liability for environmental remediation and other environmental costs is accrued when the Company considers it probable and can reasonably estimate the costs. Environmental costs and accruals, including that related to our legacy chemical distribution operations, presently are not material to our operations or financial position. Although there is no assurance that existing or future environmental laws applicable to our operations or products will not have a material adverse impact on our operations or financial condition, we do not currently anticipate material capital expenditures for environmental matters. Other than the expected expenditures that may be required in connection with our legacy chemical distribution operations, we do not anticipate making substantial capital expenditures either for environmental issues or to comply with environmental laws, regulations, or government guidance in the future. The amount of our capital expenditures for environmental compliance was not material in 2021 and is not expected to be material in the next year.

Climate Change Regulation: Governments in the U.S. and abroad are considering new or expanded laws to address climate change. Such laws may include limitations on greenhouse gas (“GHG”) emissions, mandates that companies implement processes to monitor and disclose climate-related matters, additional taxes or offset charges on specified energy sources, and other requirements. Compliance with climate-related laws may be further complicated by disparate regulatory approaches in various jurisdictions. New or expanded climate-related laws could impose substantial costs on us. Until the timing and extent of climate-related laws are clarified, we cannot predict their potential effect on our capital expenditures or our results of operations.
Other Information about the Business
Customers: During 2018,2021, sales to our ten largest customers, including GPOsgroup purchasing organizations (“GPOs”) accounted for approximately 51.7%51% of our total consolidated revenues. Sales to our largest customer, CVS Health Corporation (“CVS”), accounted for approximately 19.9%21% of our total consolidated revenues. At March 31, 2018, trade accounts receivable fromrevenues in 2021. In May 2019, we extended our pharmaceutical distribution relationship with CVS to June 2023. Our ten largest customers werecomprised approximately 24.9%32%, and CVS was approximately 19%, of total trade accounts receivable. Accounts receivable from CVS were approximately 16.4% of total trade accounts receivable.at March 31, 2021. We also have agreements with GPOs, each of which functions as a purchasing agent on behalf of member hospitals, pharmacies and other healthcare providers, as well as with government entities and agencies. The accounts receivable balances are with individual members of the GPOs, and therefore no significant concentration of credit risk exists. Substantially all of these revenues and accounts receivable are included in our Distribution SolutionsU.S. Pharmaceutical segment.
Suppliers: We obtain pharmaceutical and other products from manufacturers, none of which accounted for more than 6%7% of our purchases in 2018.2021. The loss of a supplier could adversely affect our business if alternate sources of supply are unavailable. We believe that our relationships with our suppliers are generally sound. The ten largest suppliers in 20182021 accounted for approximately 41%50% of our purchases.
A significant portionSome of our distribution arrangements with the manufacturers provides us compensation based on a percentage of our purchases. In addition, we have certain distribution arrangements with pharmaceutical manufacturers that include an inflation-based compensation component whereby we benefit when the manufacturers increase their prices as we sell our existing inventory at the new higher prices. For these manufacturers, a reduction in the frequency and magnitude of price increases, as well as restrictions in the amount of inventory available to us, could have an adverse impact on our gross profit margin.
Research and Development: Research and development (“R&D”) costsexpenses were $125$74 million, $341$96 million, and $392$71 million during 2018, 20172021, 2020, and 2016. Development expenditures in 2017 and 2016 were primarily incurred by our MTS segment. R&D costs were lower in 2018 due to the 2017 contribution of the majority of our MTS businesses. Additional information regarding our development activities is included in Financial Note 1, “Significant Accounting Policies,” to the consolidated financial statements appearing in this Annual Report on Form 10-K.2019, respectively.
Environmental Regulation: Our operations are subject to regulations under various federal, state, local and foreign laws concerning the environment, including laws addressing the discharge of pollutants into the air and water, the management and disposal of hazardous substances and wastes, and the cleanup of contaminated sites. We could incur substantial costs, including cleanup costs, fines and civil or criminal sanctions and third-party damage or personal injury claims, if in the future we were to violate or become liable under environmental laws.

The reader shouldimmaterial. This is not consider this list to be a complete statement of all potential risks and uncertainties.

Litigation and Regulatory Risks
We experience costly and disruptive legal disputes.
We are routinely named as a defendant in litigation or regulatory proceedings and other legal disputes, which may include asserted class action litigation, such as those described in Financial Note 19, “Commitments and Contingent Liabilities,” to the consolidated financial statements in this report. Regulatory proceedings might involve allegations such as false claims, healthcare fraud and abuse, and antitrust violations. Civil litigation proceedings might involve commercial, employment, environmental, intellectual property, tort and other claims. Despite valid defenses that we assert, legal disputes are often costly, time-consuming, distracting to management and disruptive to normal business operations. The outcome of legal disputes is difficult to predict. Outcomes can occur that are not justified by the evidence or existing law. The uncertainty and expense associated with unresolved legal disputes might harm our business and reputation even if the matter is favorably resolved. Accordingly, any legal dispute might have a materially adverse impact on our reputation, our business operations and our financial position or results of operations.
We might experience losses not covered by insurance.
Our business exposes us to risks that are inherent in the distribution, manufacturing, dispensing and administration of pharmaceuticals and medical-surgical supplies, the provision of ancillary services, the conduct of our payer businesses and the provision of products that assist clinical decision-making and relate to patient medical histories and treatment plans. For example, pharmacy operations are exposed to risks such as improper filling of prescriptions, mislabeling of prescriptions, inadequacy of warnings, unintentional distribution of counterfeit drugs and expiration of drugs. Although we seek to maintain adequate insurance coverage, such as property insurance for inventory and professional and general liability insurance, coverages on acceptable terms might be unavailable, or coverages might not cover our losses. We generally seek to limit our contractual exposure, but limitations of liability or indemnity provisions in our contracts may not be enforceable or adequately protect us from liability. Uninsured losses might have a materially adverse impact on our business operations and our financial position or results of operations.
We experience costly legal disputes, government actions and adverse publicity regarding our role in distributing controlled substances such as opioids.
The Company is a defendant in approximately 3,200 cases alleging claims related to the distribution of controlled substances (opioids), as described in Financial Note 19, “Commitments and Contingent Liabilities,” to the consolidated financial statements in this report. We regularly are named as a defendant in similar, new cases. The plaintiffs in those cases include governmental entities (such as states, provinces, counties and municipalities) as well as businesses, groups and individuals. The cases allege violations of controlled substance laws and other laws, and they make common law claims such as negligence and public nuisance. Many of these cases raise novel theories of liability. Any proceedings can have unexpected outcomes that are not justified by evidence or existing law. All proceedings involve significant expense, management time and distraction, and risk of loss that can be difficult to predict or quantify. It is not uncommon for claims to be resolved over many years. Proceedings can result in monetary damages, penalties and fines, and injunctive or other relief. Although the Company has valid defenses and is vigorously defending itself, some proceedings have been and others may be resolved by negotiated outcome. Our reputation has been and may continue to be impacted by publicity regarding the litigation and related allegations. The adverse outcome of legal proceedings might have a materially adverse impact on our business operations and our financial position or results of operations.

We might experience increased costs to distribute controlled substances such as opioids.
ChangesLegislative, regulatory or industry measures related to the distribution of controlled substances such as prescription opioids could affect our business in ways that we may not be able to predict. For example, some states have passed legislation that could require us to pay taxes or assessments on the United States healthcare industrydistribution of opioid medications in those states and regulatory environment couldother states have considered similar legislation. Liabilities for taxes or assessments or other costs of compliance under any such laws might have a materialmaterially adverse impact on our reputation, business operations, and our financial position or results of operations.
Many of our products and servicesWe are intended to function within the structure of the healthcare financing and reimbursement system currently being used in the United States. In recent years, the healthcare industry in the United States has changed significantly in an effort to enhance efficiencies, reduce costs and improve patient outcomes. These changes have included cuts in Medicare and Medicaid reimbursement levels, changes in the basis for payments, shifting away from fee-for-service and towards value-based payments and risk-sharing models, increases in the use of managed care and consolidation in the healthcare industry. We expect the healthcare industry in the United States to continue to change and for healthcare delivery models to evolve in the future.
Changes in the healthcare industry’s or our pharmaceutical suppliers’ pricing, selling, inventory, distribution or supply policies or practices could significantly reduce our revenues and net income. Additionally, if we experience disruptions in our supply of generic drugs, our margins could be adversely affected. Due to the diverse range of healthcare supply management and healthcare information technology products and services that we offer, such changes could have a material adverse impact on our results of operations, while not affecting some of our competitors who offer a narrower range of products and services.
The majority of our U.S. pharmaceutical distribution business agreements with manufacturers are structured to ensure that we are appropriately and predictably compensated for the services we provide. However, failure to successfully renew these contracts in a timely and favorable manner could have a material adverse impact on our results of operations. Certain distribution business agreements we entered into with manufacturers continue to have pharmaceutical price inflation as a component of our compensation. Consequently, our results of operations could be adversely affected if the frequency or magnitude of pharmaceutical price increases or decreases, which we do not control. In addition, we distribute generic pharmaceuticals, which can be subject to both price deflationextensive, complex and price inflation. Our generic pharmaceutical sourcing program has benefited from the joint sourcing entity, ClarusONE. If ClarusONE does not continue to be successful, our margins could be adversely affected. Our Distribution Solutions segment experienced weaker pharmaceutical pricing trends over the last three years. Continued volatility in the availability, pricing trends or reimbursement of these generic drugs, or significant fluctuations in the nature, frequencychallenging healthcare and magnitude of generic pharmaceutical launches, could have a material adverse impact on our results of operations. Additionally, any future changes in branded and generics drug pricing could be significantly different than our projections.other laws.
Generic drug manufacturers are increasingly challenging the validity or enforceability of patents on branded pharmaceutical products. During the pendency of these legal challenges, a generics manufacturer may begin manufacturing and selling a generic version of the branded product prior to the final resolution of its legal challenge over the branded product’s patent. To the extent we source, contract manufacture, and distribute such generic products, the brand-name company could assert infringement claims against us. While we generally obtain indemnification against such claims from generic manufacturers as a condition of distributing their products, there can be no assurances that these rights will be adequate or sufficient to protect us.
The healthcareOur industry is highly regulated, and further regulation of our distribution businesses and technology products and services could impose increased costs, negatively impact our profit margins and the profit margins of our customers, delay the introduction or implementation of our new products, or otherwise negatively impact our business and expose the Company to litigation and regulatory investigations. For example, we are subject to many environmental and hazardous materials regulations, including those relating to radiation-emitting equipment operated at U.S. Oncology Network practices. Additionally, we are subject to various routine agency (e.g., Drug Enforcement Administration (“DEA”), the U.S. Food and Drug Administration (“FDA”)) inspections to determine compliance with various federal regulations. Any noncompliance by us with applicable laws or the failure to maintain, renew or obtain necessary permits and licenses could lead to litigation and might have a materially adverse impact on our business operations and our financial position or results of operations.
Healthcare Fraud: We are subject to extensive and frequently changing local, state and federal laws and regulations relating to healthcare fraud, waste and abuse.
Local, state and federal governments continue to strengthen their position and scrutiny over practices involving or allegedly involving fraud, waste and abuse affecting Medicare, Medicaid and other government healthcare programs. Our relationships with pharmaceutical and medical-surgicalmedical surgical product manufacturers and healthcare providers, as well as our provision of products and services to government entities, subject our business to laws and regulations on fraud and abuse, which among other things: (1) prohibit persons from soliciting, offering, receiving or paying any remuneration in order to induce the referral of a patient for treatment or to induce the ordering or purchasing of items or services that are in any way paid for by Medicare, Medicaid or other government-sponsored healthcare programs; (2) impose a number ofmany restrictions upon referring physicians and providers of designated health services under Medicare and Medicaid programs; and (3) prohibit the knowing submission of a false or fraudulent claim for payment to, and knowing retention of an overpayment by, a federal healthcare program such as Medicare and Medicaid. Many of thethese laws, regulations, applicable to us,and government guidance, including those relating to marketing incentives, are vague or indefinite and have not been interpreted by the courts. The regulationslaws may be interpreted or applied by a prosecutorial, regulatory, or judicial authority in a manner that could require us to make changes in our operations. If we failFailures to comply with applicable laws subject us to federal or state government investigations or qui tam actions, and regulations, we could become liableto liability for damages and suffer civil and criminal penalties, including the loss of licenses or our ability to participate in Medicare, Medicaid and other federal and state healthcare programs.

Reimbursements: Both our profit margins and the profit margins of our customers may be adversely affected by laws and regulations reducing reimbursement rates for pharmaceuticals, medical treatments and related services, or changing the methodology by which reimbursement levels are determined. For example, the Patient Protection and Affordable Care Act and the Health Care and Education Reconciliation Act (collectively the “Affordable Care Act”), signed into law in 2010, revised, subject to rulemaking, the federal upper limits (“FUL”) for Medicaid reimbursement for multiple source generic drugs available for purchase by retail community pharmacies on a nationwide basis. On February 1, 2016, the Centers for Medicare and Medicaid Services (“CMS”) published the Covered Outpatient Drugs final rule. The final rule, with limited exceptions, establishes the FUL to be 175% of the weighted average (determined on the basis of utilization across a drug molecule when multiple sources are available) of the most recently reported monthly average manufacturer price (“AMP”). Additionally, the final rule established actual acquisition cost as the basis by which states should determine their ingredient cost reimbursement, addressed the sufficiency of dispensing fees to reflect the cost of the pharmacist’s professional services and cost to dispense drugs to Medicaid beneficiaries, and clarified that states are required to evaluate the sufficiency of both ingredient cost and professional dispensing fee when proposing changes to either component. Use of the revised AMP-based FUL may result in a reduction in the Medicaid reimbursement rates to our customers for certain pharmaceuticals, which could indirectly impact the prices that we can charge our customers and cause corresponding declines in our profitability.
The federal government may adopt measures that could reduce Medicare and/or Medicaid spending, or impose additional requirements on healthcare entities. For example, under the terms of the Budget Control Act of 2011, an automatic 2% reduction of Medicare program payments for all healthcare providers became generally effective for services provided on or after April 1, 2013. This automatic reduction is known as “sequestration.” Medicare generally reimburses physicians for Part B drugs at the rate of average sales price (“ASP”) plus 6%. The implementation of sequestration pursuant to the Budget Control Act of 2011 has effectively reduced reimbursement below the ASP plus 6% level for the duration of sequestration (which lasts through fiscal 2024 in the absence of additional legislation). On September 20, 2017, CMS issued a request for information seeking recommendations for payment models, which could include prescription drug models under Medicare Parts B and D and state Medicaid programs. CMS noted its interest in drug pricing and value-based purchasing models involving “novel arrangements between plans, manufacturers, and stakeholders across the supply chain.” Additionally, CMS published a proposed rule on July 20, 2017 that would cut Medicare outpatient hospital reimbursement for separately payable drugs (other than vaccines) purchased through the 340B drug pricing program at ASP minus 22.5% (with certain exceptions), rather than ASP plus 6%. CMS finalized this rule on November 1, 2017. As another example, the Medicare Access and CHIP Reauthorization Act (“MACRA”), signed into law in April 2015, seeks to reform Medicare reimbursement policy for physician fee schedule services and adopts a series of policy changes affecting a wide range of providers and suppliers. Most notably, MACRA repeals the statutory Sustainable Growth Rate formula, which has called for cuts in Medicare rates in recent years, but which Congress routinely stepped in to override the full application of the formula. Instead, after a period of stable payment updates, MACRA links physician payment updates to quality and value measurements and participation in alternative payment models. MACRA also extends certain expiring Medicare and other health policy provisions, including extending the Children’s Health Insurance Program. Additionally, concerns held by federal policymakers about the federal deficit and national debt levels could result in enactment of further federal spending reductions, further entitlement reform legislation affecting the Medicare program, or both. We cannot predict what alternative or additional deficit reduction initiatives or Medicare payment reductions, if any, will ultimately be enacted into law, or the timing or affect any such initiatives or reductions will have on us.
There can be no assurance that the preceding changes would not These sanctions might have a materialmaterially adverse impact on our business operations and our financial position or results of operations.
Operating, SecurityWe might lose our ability to purchase, compound, store or distribute pharmaceuticals and Licensure Standards: controlled substances.
We are subject to the operating and security standards of the Drug Enforcement Administration (“DEA”),DEA, the U.S. Food and Drug Administration (“FDA”),FDA, various state boards of pharmacy, state health departments, the U.S. Department of Health and Human Services (“HHS”), the CMSCenters for Medicare & Medicaid Services (“CMS”) and other comparable agencies. Certain of our businesses may be required to register for permits and/or licenses with, and comply with operating and security standards of, the DEA, FDA, HHS, CMS, various state boards of pharmacy, state health departments and/or comparable state agencies as well as foreign agencies and certain accrediting bodies, depending upon the type of operations and location of product development, manufacture, distribution, and sale. For example, we are required to hold valid DEA and state-level registrations and licenses, meet various security and operating standards and comply with the Controlled Substances Act and its accompanying regulations governing the sale, marketing, packaging, holding, distribution, and disposal of controlled substances.
As part of Noncompliance with these operating, security and licensure standards, we regularly receive requests for information and occasionally subpoenas from government authorities. In some instances, these can lead torequirements has resulted in monetary penalties and/or license revocation. Inlicensing sanctions. For example, under a January 2017 we reached an agreement with the DEA and Department of Justice pursuant to which we paid the sum of $150 million to settle all potential administrative and civil claims relating to investigations about the Company’s suspicious order reportingour practices for reporting suspicious orders of controlled substances.

Pedigree Tracking:tracking laws increase our compliance burden and our pharmaceutical distribution costs.
There have been increasing efforts by Congress and state and federal agencies, including state boards of pharmacy and departments of health and the FDA,governments to regulate the pharmaceutical distribution system in order to prevent the introduction of counterfeit, adulterated and/or mislabeled drugs into the pharmaceutical distribution system, otherwise known as pedigree tracking. In November 2013, Congress passed andFor example, the President signed into law theU.S. Drug Quality and Security Act of 2013 (“DQSA”). The DQSA establishes federal standards requiring supply-chain stakeholders requires us to participate in an electronic, interoperable, lot-levela federal prescription drug track and trace system. The law alsosystem that preempts state drug pedigree requirements. The DSQA also establishes new requirements, for drug wholesale distributors and third-party logistics providers, including licensing requirements in states that had not previously licensed such entities.
In addition, the U.S. Food and Drug Administration Amendments Act of 2007, which went into effect on October 1, 2007 requires the FDA to establish standards and identify and validate effective technologies, for the purpose of securingsuch as track and trace or authentication technologies, to secure the pharmaceutical supply chain against counterfeit drugs. These standards may include track-and-trace or authentication technologies,We also have record-keeping and other obligations under the E.U. Falsified Medicines Directive. Pedigree tracking laws such as radio frequency identification devices, 2D data matrix barcodes and other similar technologies. On March 26, 2010, the FDA released the Serialized Numerical Identifier (“SNI”) guidance for manufacturers who serialize pharmaceutical packaging. We expect to be able to accommodate these SNI regulations inincrease our distribution operations. The DQSA and other pedigree tracking laws and regulations could increase the overall regulatorycompliance burden and costs associated with our pharmaceutical distribution business,costs, and couldthey might have a materialmaterially adverse impact on our business operations and our financial position or results of operations.
Privacy: TherePrivacy and data protection laws increase our compliance burden.
We are numerous federal and state laws and regulations relatedsubject to thea variety of privacy and security of personal information. In particular, regulations promulgated pursuantdata protection laws that change frequently and have requirements that vary from jurisdiction to jurisdiction. For example, under the Health Insurance Portability and Accountability Act of 1996 (“HIPAA”) establish privacy and security standards that limit the use and disclosure of individually identifiable health information (known as “protected health information”) and require the implementation ofwe must maintain administrative, physical and technological safeguards to protect the privacy of individually identifiable health information (“protected health informationinformation”) and ensure the confidentiality, integrity and availability of electronic protected health information. We are directly subject to significant compliance obligations under privacy laws such as the General Data Protection Regulation in the European Union (“GDPR”), the Personal Information Protection and Electronic Documents Act (“PIPEDA”) in Canada, and the California Consumer Protection Act (“CCPA”). Some privacy laws prohibit the transfer of personal information to certain provisions of the regulations as a “Business Associate” through our relationships with customers.other jurisdictions. We are also directly subject to the HIPAA privacy and security regulations as a “Covered Entity” with respect to our operations as a healthcare clearinghouse, specialty pharmacy and medical surgical supply business.
The privacy regulations established under HIPAA also provide patients with rights related to understanding and controlling how their protected health information is used and disclosed. To the extent permitteddata protection compliance audits or investigations by applicable privacy regulations and our contracts with our customers, we may use and disclose protected health information to perform our services and for other limited purposes, such as creating de-identified information. Other uses and disclosures, such as marketing communications, require written authorization from the individual or must meet an exception specified under the privacy regulations. Determining whether protected health information has been sufficiently de-identifiedvarious government agencies. Failure to comply with the HIPAA privacy standardsthese laws subjects us to potential regulatory enforcement activity, fines, private litigation including class actions, and ourother costs. We also have contractual obligations may require complex factual and statistical analyses and mayto customers that might be subject to interpretation.
If we are unable to properly protect the privacy and security of protected health information entrusted to us, we could be found to have breached our contracts with our customers. Further, if we fail to comply with applicable HIPAA privacy and security standards, we could face civil and criminal penalties. HHS performs compliance audits of Covered Entities and Business Associates and enforces the HIPAA privacy and security standards. HHS has become an increasingly active regulator and has signaled its intention to continue this trend. HHS has the discretion to impose penalties without being required to attempt to resolve violations through informal means, such as implementing a corrective action plan. HHS enforcement activity can result in financial liability and reputational harm, and responses to such enforcement activity can consume significant internal resources. In addition to enforcement by HHS, state attorneys general are authorized to bring civil actions seeking either injunctions or damages in response to violations that threaten the privacy of state residents. Although we have implemented and maintain policies and processes to assist us in complying with these regulations and our contractual obligations, we cannot provide assurance regarding how these regulations will be interpreted, enforced or applied to our operations. In addition to the risks associated with enforcement activities and potential contractual liabilities, our ongoinglaws. Our efforts to comply with evolvingprivacy laws complicates our operations and regulations at the federal and state leveladds to our compliance costs. A significant privacy breach or failure to comply with privacy laws might also require us to make costly system purchases and/or modifications from time to time.

Healthcare Reform:    The Affordable Care Act (“ACA”) significantly expanded health insurance coverage to uninsured Americans and changed the way healthcare is financed by both governmental and private payers. While certain provisions of the ACA took effect immediately, others have delayed effective dates or require further rulemaking action or regulatory guidance by governmental agencies to implement and/or finalize (e.g. nondiscrimination in health programs and activities, excise tax on high-cost employer-sponsored health coverage). Further, as a result of the November 2016 U.S. presidential election, there are continued uncertainties associated with efforts to change or repeal certain provisions of the ACA or other healthcare reforms, and we cannot predict their full effect on the Company at this time. A top legislative priority of the new presidential administration and Congress may be significant reform of the ACA, as discussed above. While there is currently a substantial lack of clarity around the likelihood, timing and details of any such policies and reforms, such policies and reforms may have a materialmaterially adverse impact on our results of operations.
FDA Regulation of Medical Software:  The FDA has increasingly focused on the regulation of medical softwarereputation, business operations and health information technology products as medical devices under the federal Food, Drug and Cosmetic Act. For example, in February 2015, the FDA issued guidance to inform manufacturers and distributors of medical device data systems that it did not intend to enforce compliance with regulatory controls that apply to medical device data systems, medical image storage devices, and medical image communication devices. If the FDA chooses to regulate more of our products as medical devices, or subsequently changes or reverses its guidance regarding not enforcing regulatory controls for certain medical device products, it can impose extensive requirements upon us. If we fail to comply with the applicable requirements, the FDA could respond by imposing fines, injunctions or civil penalties, requiring recalls or product corrections, suspending production, refusing to grant pre-market clearance of products, withdrawing clearances and initiating criminal prosecution. Any additional FDA regulations governing health information technology products, once issued, may increase the cost and time to market of new or existing products or may prevent us from marketing our products. In December 2016, Congress passed and the President signed into law the 21st Century Cures Act. The 21st Century Cures Act changes the way health IT would be regulated by the FDA. The bill also carves most health IT products out of the FDA’s jurisdiction, but includes a clawback provision that would enable FDA to regulate products on a case-by-case basis if it determined they pose a risk to patient safety.
Medical Billing and Coding: Medical billing, coding and collection activities are governed by numerous federal and state civil and criminal laws. In connection with these laws, we may be subjected to federal or state government investigations and possible penalties may be imposed upon us, false claims actions may have to be defended, private payers may file claims against us and we may be excluded from Medicare, Medicaid or other government-funded healthcare programs. Any such proceeding or investigation could have a material adverse impact on our results of operations.
Our foreign operations subject us to a number of operating, economic, political and regulatory risks that may have a material adverse impact on our financial position andor results of operations.
Anti-bribery and anti-corruption laws increase our compliance burden.
We have operations based in, and we source and contract manufacture pharmaceutical and medical-surgical products in, a number of foreign countries. Moreover, in Europe, McKesson Europe AG (“McKesson Europe”), formerly known as Celesio AG, operates as a wholesale and retail company and provider of logistics and services to the pharmaceutical and healthcare sector.
Our foreign operations expose us to a number of risks including changes in trade protection laws, policies and measures and other regulatory requirements affecting trade and investment; changes in licensing regimes for pharmacies; unexpected regulatory, social, political, or economic changes in a specific country or region; changes in intellectual property, privacy and data protection; import/export regulations and trade sanctions in both the United States and foreign countries and difficulties in staffing and managing foreign operations. Political changes, labor strikes, acts of war or terrorism and natural disasters, some of which may be disruptive, can interfere with our supply chain, our customers and all of our activities in a particular location. We may also be affected by potentially adverse tax consequences and difficulties associated with repatriating cash generated or held abroad.
On June 23, 2016, voters in the United Kingdom approved an advisory referendum to withdraw from the European Union, which proposed exit (and the political, economic and other uncertainties it has raised) has exacerbated and may further exacerbate many of the risks and uncertainties described above. Negotiations on withdrawal and post-exit arrangements likely will be complex and protracted, and there can be no assurance regarding the terms, timing or consummation of any such arrangements. The proposed withdrawal could, among other potential outcomes, adversely affect the tax, tax treaty, currency, operational, legal and regulatory regimes to which our businesses in the region are subject. The withdrawal could also, among other potential outcomes, disrupt the free movement of goods, services and people between the United Kingdom and the European Union and significantly disrupt trade between the United Kingdom and the European Union and other parties. Further, uncertainty around these and related issues could lead to adverse effects on the economy of the United Kingdom and the other economies in which we operate. There can be no assurance that any or all of these events will not have a material adverse effect on our results of operations.

In addition, foreign operations are also subject to risks of violations of laws prohibiting improper payments and bribery, including the U.S. Foreign Corrupt Practices Act, the U.K. Bribery Act and similar regulations in foreign jurisdictions. The U.K. Bribery Act, for example, prohibits both domestic and international bribery, as well as bribery across both private and public sectors. An organization that fails to prevent bribery committed by anyone associated with the organization can be charged under the U.K. Bribery Act unless the organization can establish the defense of having implemented adequate procedures to prevent bribery. FailureOur failure to comply with these laws couldmight subject us to civil and criminal penalties that couldmight have a materialmaterially adverse impact on our financial position and results of operations.
We also may experience difficulties and delays inherent in sourcing products and contract manufacturing from foreign countries, including but not limited to: (1) difficulties in complying with the requirements of applicable federal, state and local governmental authorities in the United States and of foreign regulatory authorities; (2) inability to increase production capacity commensurate with demand or the failure to predict market demand; (3) other manufacturing or distribution problems including changes in types of products produced, limits to manufacturing capacity due to regulatory requirements, physical limitations, or scarce or inadequate resources that could impact continuous supply; and (4) damage to our reputation, due to real or perceived quality issues. For example, the FDA has conducted investigations and banned certain generics manufacturers from selling certain raw materials and drug ingredients in the U.S. from overseas plants due to quality issues. Difficulties in manufacturing or access to raw materials could result in production shutdowns, product shortages and other similar delays in product manufacturing that could have a material adverse impact on our financial position and results of operations.
Changes in the Canadian healthcare industry and regulatory environment could have a material adverse impact on our results of operations.
Provincial governments in Canada provide partial funding for the purchase of pharmaceuticals and independently regulate the sale and reimbursement of drugs. Provincial governments in Canada have introduced significant changes in recent years in an effort to reduce the costs of publicly funded health programs. For instance, to reduce the cost for taxpayers, provincial governments have taken and will continue to take steps to reform the rules regarding the sale of generic drugs. These changes include increased powers of investigation, reporting and enforcement for provincial regulatory agencies, the significant lowering of prices for generic pharmaceuticals and, in some provinces, changes to the allowable amounts of professional allowances paid to pharmacists by generic manufacturers and the tendering of generic molecules on provincial drug formularies. These reforms may adversely affect the distribution of drugs as well as the pricing for prescription drugs for the Company’s operations in Canada. Additional provinces have implemented or are considering similar changes, which would also lower pharmaceutical pricing and service fees. Individually or in combination, such changes in the Canadian healthcare environment may significantly reduce our Canadian revenue and operating profit.
General European economic conditions, together with austerity measures being taken by certain European governments, could have a material adverse impact on our results of operations.
A slowdown within the European economy could affect our business in Europe by reducing the prices our customers may be able or willing to pay for our products and services. A slowdown may also reduce the demand for our products. Either of these could result in a material adverse impact on our results of operations.
In addition, in many European countries the government provides or subsidizes healthcare to consumers and regulates pharmaceutical prices, patient eligibility, and reimbursement levels to control costs for the government-sponsored healthcare system. In recent years, in response to the recessionary environment and financial crisis in Europe, a number of European governments, including the government in the United Kingdom in the past year, have announced or implemented austerity measures to reduce healthcare spending and constrain overall government expenditures. These measures, which include efforts aimed at reforming healthcare coverage and reducing healthcare costs, continue to exert pressure on the pricing of and reimbursement timelines for pharmaceuticals and may cause our customers to purchase fewer of our products and services and reduce the prices they are willing to pay.
Countries with existing healthcare-related austerity measures may impose additional laws, regulations, or requirements on the healthcare industry. In addition, European governments that have not yet imposed healthcare-related austerity measures may impose them in the future. New austerity measures may be similar to or vary from existing austerity measures and could have a material adverse impact on our results of operations.

Changes in the European regulatory environment regarding privacy and data protection regulations could have a material adverse impact on our results of operations.
In Europe, beginning May 25, 2018, we are subject to the General Data Protection Regulation, which requires EU member states to impose restrictions on the collection and use of personal data that, in some respects, are more stringent, and impose more significant burdens on subject businesses, than current privacy standards in the United States. We may also face audits or investigations by one or more foreign government agencies relating to our compliance with these regulations that could result in the imposition of penalties or fines. The EU member state regulations establish several obligations that organizations must follow with respect to use of personal data, including a prohibition on the transfer of personal information from the EU to other countries whose laws do not protect personal data to an adequate level of privacy or security. In addition, certain member states have adopted more stringent data protection standards. The costs of compliance with, and other burdens imposed by, such laws, regulations and policies that are applicable to us may limit the use and adoption of our products and solutions and could have a material adverse impact on our results of operations.
Our results of operations, which are stated in U.S. dollars, could be adversely impacted by fluctuations in foreign currency exchange rates.
We conduct our business worldwide in U.S. dollars and the functional currencies of our foreign subsidiaries, including Euro, British pound sterling and Canadian dollar. Changes in foreign currency exchange rates could have a significant adverse impact on our financial results that are reported in the U.S. dollar. We are also exposed to foreign currency exchange rate risk related to our foreign subsidiaries, including intercompany loans denominated in non-functional currencies.
We may from time to time enter into foreign currency contracts or other derivative instruments intended to hedge a portion of our foreign currency exchange rate risks. Additionally, we may use foreign currency borrowings to hedge some of our foreign currency exchange rate risks. These hedging activities may not completely offset the adverse financial effects of unfavorable movements in foreign currency exchange rates during the time the hedges are in place.
Our business could be hindered if we are unable to complete and integrate acquisitions successfully.
An element of our strategy is to identify, pursue and consummate acquisitions that either expand or complement our business. Integration of acquisitions involves a number of significant risks, including the diversion of management’s attention to the assimilation of the operations of businesses we have acquired; difficulties in the integration of operations and systems; the realization of potential operating synergies; the assimilation and retention of the personnel of the acquired companies; accounting, regulatory or compliance issues that could arise, including internal control over financial reporting; and challenges retaining the customers of the combined businesses. Further, acquisitions may have a material adverse impact on our operating results if unanticipated expenses or charges to earnings were to occur, including unanticipated depreciation and amortization expenses over the useful lives of certain assets acquired, as well as costs related to potential impairment charges, assumed litigation and unknown liabilities. In addition, we may potentially require additional financing in order to fund future acquisitions, which may or may not be attainable and is subject to potential volatility in the credit markets. If we are unable to successfully complete and integrate strategic acquisitions in a timely manner, our business and our growth strategies could be negatively affected.
Achieving the anticipated benefits of any acquisition is subject to a number of risks and uncertainties, including foreign exchange fluctuations, challenges of managing new domestic or international operations, and whether we can ensure continued performance or market growth of products and services. The integration process is subject to a number of uncertainties and no assurance can be given that the anticipated benefits of any transaction will be realized or, if realized, the timing of its realization. It is possible that the integration process could take longer than anticipated, and could result in the loss of employees, the disruption of each company’s ongoing businesses, processes and systems, or inconsistencies in standards, controls, procedures, practices, policies and compensation arrangements. Any of these events could adversely affect our ability to achieve the anticipated benefits of an acquisition and which could have a material adverse impact on our results of operations.
Any significant diversion of management’s attention away from the ongoing businesses, and any difficulties encountered in the acquisition, transition and integration process, could adversely affect our financial results. Moreover, the failure to achieve the anticipated benefits of a transaction could result in increased costs or decreases in the amount of expected revenues, and could adversely affect our future business, financial position and operating results. Events outside of our control, including changes in regulations and laws, as well as economic trends, could also adversely affect our ability to realize the expected benefits from a transaction.

Our results of operations could be impacted if our investment in Change Healthcare fails to perform as expected.
On March 1, 2017, McKesson contributed the majority of its Core MTS Business and Change contributed substantially all of its businesses, excluding its pharmacy switch and prescription routing businesses, to form a joint venture, Change Healthcare. The purpose of the transaction was to create a new healthcare information technology company, bringing together the complementary strengths of the contributed assets to provide software and analytics, network solutions and technology-enabled services that will help customers obtain actionable insights, exchange mission-critical information, control costs, optimize revenue opportunities, increase cash flow and effectively navigate the shift to value-based healthcare. Change Healthcare is jointly governed by McKesson and Change. Operating a business under joint governance of unaffiliated, controlling members could lead to conflicts of interest or deadlocks on important and time-sensitive operational, financial or strategic decisions, and will require additional organizational formalities as well as time-consuming procedures for sharing information and making decisions. If we are unable to manage our joint venture relationship and to realize the strategic and financial benefits that we expect, including an initial public offering of Change Healthcare, such inability to manage the relationship or realize benefits may have a material adverse impact on our results of operations.
Our business and results of operations could be impacted if we fail to manage and complete divestitures.
We regularly evaluate our portfolio in order to determine whether an asset or business may no longer help us meet our objectives. When we decide to sell assets or a business, we may encounter difficulty in finding buyers or alternative exit strategies on acceptable terms in a timely manner, which could delay the achievement of our strategic objectives. We may also experience greater dissynergies than expected, and the impact of the divestiture on our revenue growth may be larger than projected. After reaching an agreement with a buyer, we are subject to satisfaction of pre-closing conditions as well as to necessary regulatory and governmental approvals, which, if not satisfied or obtained, may prevent us from completing the sale. Dispositions may also involve continued financial involvement in the divested business, such as through continuing equity ownership, guarantees, indemnities or other financial obligations. Under these arrangements, performance by the divested businesses or other conditions outside of our control could have a material adverse impact on our results of operations.
We are subject to legal and regulatory proceedings that could have a material adverse impact on our financial position and results of operations.
From time to time and in the ordinary course of our business, we and certain of our subsidiaries may become involved in various legal and regulatory proceedings involving false claims, healthcare fraud and abuse, antitrust, class actions, commercial, employment, environmental, intellectual property, licensing, tort and other various claims. For example, the Company is a defendant in many cases alleging claims related to the distribution of controlled substances to pharmacies, often together with other pharmaceutical wholesale distributors and pharmaceutical manufacturers and retail pharmacy chains named as defendants. The Company has been served with many complaints, often brought by governmental entities (including counties and municipalities) that allege violations of controlled substance laws and various other statutes in addition to common law claims, including negligence and public nuisance, and seek monetary damages and equitable relief. Some states and other governmental entities have indicated that they are considering filing similar suits. All such legal proceedings are inherently unpredictable, and the outcome can result in excessive verdicts and/or injunctive relief that may affect how we operate our business or we may enter into settlements of claims for monetary payments. In some cases, substantial non-economic remedies or punitive damages may be sought. For some complaints filed against the Company, we are currently unable to estimate the amount of possible losses that might be incurred should these legal proceedings be resolved against the Company.
The outcome of litigation and other legal matters is always uncertain and outcomes that are not justified by the evidence or existing law can occur. The Company believes that it has valid defenses to the legal matters pending against it and is defending itself vigorously. Nevertheless, it is possible that resolution of one or any combination of more than one legal matter could result in a material adverse impact on our financial position or results of operations.
Litigation is costly, time-consuming and disruptive to normal business operations. The defense of these matters could also result in continued diversion of our management’s time and attention away from business operations, which could also harm our business. Even if these matters are not resolved against us, the uncertainty and expense associated with unresolved legal proceedings could harm our business and reputation.

Company and Operational Risks
Competition and industry consolidation may erode our profit.
Our Distribution Solutions segment (and commencing in first quarter of 2019, our reportable segments including U.S. Pharmaceutical and Specialty Solutions, European Pharmaceutical Solutions, Medical-Surgical Solutions and Other) faces a highly competitive global environment with strong competitionWe might record significant charges from international, national, regional and local full-line, short-line and specialty distributors, service merchandisers, self-warehousing chain drug stores, manufacturers engaged in direct distribution, third-party logistics companies and large payer organizations. In addition, this segment faces competition from various other service providers and from pharmaceuticalimpairment to goodwill, intangibles and other healthcare manufacturers as well as other potential customers of the segment, which may from time-to-time decide to develop, for their own internal needs, supply management capabilities that would otherwise be provided by the segment. In all areas, key competitive factors include price, quality of service, breadth of product lines, innovation and, in some cases, convenience to the customer.
In addition, in recent years, the healthcare industry has been subject to increasing consolidation. As a result, a small number of very large pharmaceutical suppliers could control a significant share of the market. Accordingly, we could depend on fewer suppliers for our products and therefore we may be less able to negotiate price terms with suppliers. Many of our customers, including healthcare organizations that purchase our products and services, have also consolidated to create larger enterprises with greater market power. If this consolidation trend continues among our customers, suppliers and competitors, it could reduce the number of market participants and give the resulting enterprises greater bargaining power, which may lead to erosion of the prices for our products and services. It would also increase counter-party credit risk as the number of market participants decreases. In addition, when our customers combine, they often consolidate infrastructure including IT systems, which in turn may erode the diversity of our customer and revenue base.
Our McKesson Prescription Technology Solutions business experiences substantial competition from many companies, including other software services firms, consulting firms, shared service vendors, certain hospitals and hospital groups, payers, care management organizations, hardware vendors and internet-based companies with technology applicable to the healthcare industry. Competition varies in size from small to large companies, in geographical coverage and in scope and breadth of products and services offered.
These competitive pressures and industry consolidation could have a material adverse impact on our results of operations.
A material reduction in purchases or the loss of a large customer or group purchasing organization, as well as substantial defaults in payment by a large customer or group purchasing organization, could have a material adverse impact on our financial position and results of operations.
In recent years, a significant portion of our revenue growth has been with a limited number of large customers. During 2018, sales to our ten largest customers, including group purchasing organizations (“GPOs”) accounted for approximately 51.7% of our total consolidated revenues. Sales to our largest customer, CVS Health (“CVS”), accounted for approximately 19.9% of our total consolidated revenues. At March 31, 2018, trade accounts receivable from our ten largest customers were approximately 24.9% of total trade accounts receivable. Accounts receivable from CVS were approximately 16.4% of total trade accounts receivable. As a result, our sales and credit concentration is significant. We also have agreements with GPOs, each of which functions as a purchasing agent on behalf of member hospitals, pharmacies and other healthcare providers, as well as with government entities and agencies. A material default in payment, a material reduction in purchases from these or any other large customers, or the loss of a large customer or GPO could have a material adverse impact on our financial position, results of operations and liquidity.
We generally sell our products and services to customers on credit that is short-term in nature and unsecured. Any adverse change in general economic conditions can adversely reduce sales to our customers, affect consumer buying practices or cause our customers to delay or be unable to pay accounts receivable owed to us, which may in turn materially reduce our revenue growth and cause a material decrease in our profitability and cash flow. Further, interest rate fluctuations and changes in capital market conditions may also affect our customers’ ability to obtain credit to finance their business under acceptable terms, which in turn may materially reduce our revenue growth and cause a decrease in our profitability.

Contracts with foreign and domestic government entities and their agencies pose additional risks relating to future funding and compliance.
Contracts with foreign and domestic government entities and their agencies are subject to various uncertainties, restrictions and regulations, including oversight audits by various government authorities. Government contracts also are exposed to uncertainties associated with funding. Contracts with the U.S. federal government, for example, are subject to the uncertainties of Congressional funding. Governments are typically under no obligation to maintain funding at any specific level, and funds for government programs may even be eliminated. As a result, our government clients may terminate our contracts for convenience or decide not to renew our contracts with little or no prior notice. The loss of such contracts could have a material adverse impact on our results of operations.
In addition, because government contracts are subject to specific procurement regulations and a variety of other socio-economic requirements, we must comply with such requirements. For example, for contracts with the U.S. federal government, with certain exceptions, we must comply with the Federal Acquisition Regulation, the U.S. False Claims Act, the Procurement Integrity Act, the Buy American Act and the Trade Agreements Act. We must also comply with various other domestic and foreign government regulations and requirements as well as various statutes related to employment practices, environmental protection, recordkeeping and accounting. These regulations and requirements affect how we transact business with our clients and, in some instances, impose additional costs on our business operations. Government contracts also contain terms that expose us to higher levels of risk and potential liability than non-government contracts.
We also are subject to government audits, investigations, and oversight proceedings. For example, government agencies routinely review and audit government contractors to determine whether contractors are complying with specific contractual or legal requirements. If we violate these rules or regulations, fail to comply with a contractual or other requirement, or do not satisfy an audit, a variety of penalties can be imposed by a government including monetary damages and criminal and civil penalties. In addition, any of our government contracts could be terminated or we could be suspended or debarred from all government contract work. The occurrence of any of these actions could harm our reputation and could have a material adverse impact on our results of operations.
Our future results could be materially affected by a number of public health issues whether occurring in the United States or abroad.
Public health issues, whether occurring in the United States or abroad, could disrupt our operations, disrupt the operations of suppliers or customers, or have a broader adverse impact on consumer spending and confidence levels that would negatively affect our suppliers and customers. We have developed contingency plans to address infectious disease scenarios and the potential impact on our operations, and we will continue to update these plans as necessary. However, there can be no assurance that these plans will be effective in eliminating the negative impact of any such diseases on the Company’s operating results. We may be required to suspend operations in some or all of our locations, which could have a material adverse impact on our financial position and results of operations.
We rely on sophisticated computer systems to perform our business operations. Although we, our customers and our external service providers use a variety of security measures to protect our and their computer systems, a failure or compromise of our, our customers’ or our external service providers’ computer systems from a cyberattack, natural disaster, or malfunction may result in material adverse operational and financial consequences.
Our business relies on the secure electronic transmission, storage, and hosting of sensitive information, including personally identifiable information, protected health information, financial information and other sensitive information relating to our customers, company and workforce. We routinely process, store and transmit large amounts of data in our operations, including sensitive personal information, protected health information, financial information, and confidential information relating to our business or third parties. Some of the data that we process, store and transmit may travel outside of the United States. Additionally, we outsource some important IT functions to external service providers worldwide.
Our industry is subject to various evolving federal, state and international data and security laws and regulations, which impose operational costs to achieve compliance. Any failure to comply with these laws and regulations could result in regulatory enforcement activity and fines. In addition, compliance with these requirements could require changes in business practices, complicate our operations, and increase our oversight needs.

The constant evolution of cyberattacks has caused us to spend more time and money to deal with increasingly sophisticated attacks. Despite our implementation of a variety of physical, technical and administrative security measures, our, our customers’ and our external service providers’ computer systems could be subject to cyberattacks and unauthorized access, such as physical and electronic break-ins or unauthorized tampering. Like other global companies, we and our customers have experienced threats to data and systems, including malware and ransomware attacks, unauthorized access, system failures, and disruptions.
A failure or compromise of our, our customers’ or our external service providers’ computer systems may result in business disruption or jeopardize the confidential, proprietary, and sensitive information processed, stored, and transmitted through such computer systems. Such an event may result in significant damage to our reputation, financial losses, litigation, increased costs, regulatory penalties, notification costs, remediation expenses, customer attrition, brand impairment, or other business harm. These risks may increase in the future as we continue to expand our internet and mobile strategies and to build an integrated digital enterprise.
We could experience losses or liability not covered by insurance.
In order to provide prompt and complete service to our major Distribution Solutions segment’s customers, we maintain significant product inventory at certain of our distribution centers. While we seek to maintain property insurance coverage in amounts sufficient for our business, there can be no assurance that our property insurance will be adequate or available on acceptable terms. One or more large casualty losses caused by fire, earthquake or other natural disaster in excess of our coverage limits could have a material adverse impact on our results of operations.
Our business exposes us to risks that are inherent in the distribution, manufacturing, dispensing and administration of pharmaceuticals and medical-surgical supplies, the provision of ancillary services, the conduct of our payer businesses and the provision of products that assist clinical decision making and relate to patient medical histories and treatment plans. If customers or individuals assert liability claims against our products and/or services, any ensuing litigation, regardless of outcome, could result in a substantial cost to us, divert management’s attention from operations and decrease market acceptance of our products. We attempt to limit our liability to customers by contract; however, the limitations of liability set forth in the contracts may not be enforceable or may not otherwise protect us from liability for damages. Additionally, we may be subject to claims that are not explicitly covered by contract, such as a claim directly by a patient. We also maintain general liability coverage; however, this coverage may not continue to be available on acceptable terms, may not be available in sufficient amounts to cover one or more large claims against us and may include larger self-insured retentions or exclusions for certain products. In addition, the insurer might disclaim coverage as to any future claim. A successful product or professional liability claim not fully covered by our insurance could have a material adverse impact on our results of operations.
Transactions like our acquisitions of McKesson Europe and Rexall Health expose us to additional risks related to providing pharmacy services. Pharmacies are exposed to risks inherent in the packaging and distribution of pharmaceuticals and other healthcare products, such as with respect to improper filling of prescriptions, labeling of prescriptions, adequacy of warnings, unintentional distribution of counterfeit drugs and expiration of drugs. Although we maintain liability insurance, the coverage may not be adequate to protect us against future claims. If our insurance coverage proves to be inadequate or unavailable, or we suffer reputational harm as a result of an error or omission, it could have a material adverse impact on our results of operations.
Proprietary protections may not be adequate, and products may be found to infringe the rights of third parties.
We rely on a combination of trade secret, patent, copyright and trademark laws, nondisclosure and other contractual provisions and technical measures to protect our proprietary rights in our products and solutions. There can be no assurance that these protections will be adequate or that our competitors will not independently develop products or services that are equivalent or superior to ours. In addition, despite protective measures, we may be subject to unauthorized use of our technology due to copying, reverse-engineering or other infringement. Although we believe that our products and services do not infringe the proprietary rights of third parties, from time to time third parties have asserted infringement claims against us, and there can be no assurance that third parties will not assert infringement claims against us in the future. If we were found to be infringing others’ rights, we may be required to pay substantial damage awards and forced to develop non-infringing products or services, obtain a license or cease selling or using the products or services that contain the infringing elements. Additionally, we may find it necessary to initiate litigation to protect our trade secrets, to enforce our patent, copyright and trademark rights and to determine the scope and validity of the proprietary rights of others. These types of litigation can be costly and time consuming. These litigation expenses, damage payments or costs of developing replacement products or services could have a material adverse impact on our results of operations.

System errors or failures of our products or services to conform to specifications could cause unforeseen liabilities or injury, harm our reputation and have a material adverse impact on our results of operations.
The software and technology services that we sell or operate are complex. As with complex systems offered by others, our software and technology services may contain errors, especially when first introduced. For example, some of our systems are intended to provide information to healthcare professionals in the course of delivering patient care. Therefore, users of our software and technology services have a greater sensitivity to errors than the general market for software products. If clinicians’ use of our software and technology services leads to faulty clinical decisions or injury to patients, we could be subject to claims or litigation by our customers, clinicians or patients. In addition, such failures could damage our reputation and could negatively affect future sales.
Failure of a customer’s system to perform in accordance with our documentation could constitute a breach of warranty and could require us to incur additional expense in order to make the system comply with the documentation. If such failure is not remedied in a timely manner, it could constitute a material breach under a contract, allowing the client to cancel the contract, obtain refunds of amounts previously paid or assert claims for significant damages.
Various risks could interrupt customers’ access to their data residing in our service center, exposing us to significant costs.
We provide remote hosting services that involve operating both our software and the software of third-party vendors for our customers. The ability to access the systems and the data that we host and support on demand is critical to our customers. Our operations and facilities are vulnerable to interruption and/or damage from a number of sources, many of which are beyond our control, including, without limitation: (1) power loss and telecommunications failures; (2) fire, flood, hurricane and other natural disasters; (3) software and hardware errors, failures or crashes; and (4) cyberattacks, computer viruses, hacking and other similar disruptive problems. We attempt to mitigate these risks through various means including disaster recovery plans, separate test systems and change controls, information security procedures, and continued development and enhancement of our cyber security, but our precautions may not protect against all risks. If customers’ access is interrupted because of problems in the operation of our facilities, we could be exposed to significant claims, particularly if the access interruption is associated with problems in the timely delivery of medical care. If customers’ access is interrupted from failure or breach of our operational or information security systems, or those of our contractors or third-party service providers, we could suffer reputational harm or be exposed to liabilities arising from the unauthorized and improper use or disclosure of confidential or proprietary information. We must maintain disaster recovery and business continuity plans that rely upon third-party providers of related services and if those vendors fail us at a time that our center is not operating correctly, we could incur a loss of revenue and liability for failure to fulfill our contractual service commitments. Any significant instances of system downtime could negatively affect our reputation and ability to sell our remote hosting services.
We may be required to record a significant charge to earnings if our goodwill, intangible and other long-lived assets or investments become impaired.investments.
We are required under U.S. generally accepted accounting principlesGenerally Accepted Accounting Principles (“GAAP”) to test our goodwill for impairment annually or more frequently if indicators for potential impairment exist. Indicators that are considered include significant changes in performance relative to expected operating results, significant changes in the use of the assets, significant negative industry or economic trends or a significant decline in the Company’s stock price and/or market capitalization for a sustained period of time. In addition, we periodically review our intangible and other long-lived assets for impairment when events or changes in circumstances, such as a divestiture, indicate the carrying value may not be recoverable. Factors that may be considered a change in circumstances indicating that the carrying value of our intangible and other long-lived assets may not be recoverable include slower growth rates, the loss of a significant customer, burdensome new laws or divestiture of a business or asset for less than its carrying value. We may be required to record a significant charge to earnings in our consolidated financial statements during the period in which any impairment of our goodwill or intangible and other long-lived assets is determined. This could have a material adverse impact on our results of operations. There are inherent uncertainties in management’s estimates, judgments and assumptions used in assessing recoverability of goodwill, intangible and other long-lived assets. Any material changes in key assumptions, including failure to meet business plans, negative changes in government reimbursement rates, a deterioration in the U.S. and global financial markets, an increase in interest rate or an increase in the cost of equity financing by market participants within the industry or other unanticipated events and circumstances, may decrease the projected cash flows or increase the discount rates and could potentially result in an impairment charge.

We may experience declines in its fair value. A decline in the fair value of our Change Healthcare investment may require that we review the carrying value for potential impairment,goodwill or intangible and such review could result in an impairment charge to our consolidated statements of operations.
Tax legislation initiatives or challenges to our tax positions couldother long-lived assets is determined, which might have a materialmaterially adverse impact on our business operations and our financial position or results of operations.
We are a large multinational corporation withexperience cybersecurity incidents that might significantly compromise our technology systems or might result in material data breaches.
We and our external service providers use technology and systems to perform our business operations, insuch as the United Statessecure electronic transmission, processing, storage and international jurisdictions. As such, we arehosting of sensitive information, including protected health information and other types of personal information, confidential financial information, proprietary information, and other sensitive information relating to our customers, company and workforce. Despite physical, technical, and administrative security measures, our technology systems and operations have been, and likely will continue to be, subject to the tax laws and regulationscyberattacks from sources beyond our control. Cybersecurity incidents include actual or attempted unauthorized access, tampering, malware insertion, ransomware attacks or other system integrity events. The risk of the United States federal, state and local governments and of many international jurisdictions. From time to time, legislationcyberattacks may be enacted that could adversely affect our tax positions. There can be no assurance that our effective tax rate and the resulting cash flow will not be adversely affected by these changes in legislation. On December 22, 2017, the Tax Cuts and Jobs Act of 2017 (the "2017 Tax Act") was enacted and contains significant changes to U.S. income tax law. Effective in 2018, the 2017 Tax Act reduces the U.S. statutory tax rate from 35% to 21%. Effective in 2019, it creates new taxes focused on foreign-sourced earnings and related-party payments. In addition, we were subjectincreased due to a one-time transition tax in 2018 on accumulated foreign subsidiary earnings not previously subject to U.S. income tax. The SEC issued Staff Accounting Bulletin No. 118 ("SAB 118") on December 22, 2017, which allows companies to record provisional amounts duringvariety of factors, both internal and external. A cybersecurity incident might involve a measurement period not to extend beyond one year of the enactment date. We have made reasonable estimates of the effects and recorded provisional amounts in our consolidated financial statements for the year ended March 31, 2018, in accordance with SAB 118. The U.S. Treasury Department and IRS have not yet issued regulations with respectmaterial data breach or other material impact to the 2017 Tax Act. Due to the potential for changes to tax lawsintegrity and regulations or changes to the interpretation thereof (including regulations and interpretations pertaining to the 2017 Tax Act), the ambiguity of tax laws and regulations, the subjectivity of factual interpretations, the complexityoperations of our intercompany arrangements, uncertainties regarding the geographic mixtechnology systems, which might result in litigation or regulatory action, loss of earnings incustomers or revenue, and increased expense, any particular period, and other factors, material adjustments to our tax estimates impact our provision for income taxes and our earnings per share, as well as our cash flows, in the period inof which any such adjustments are made. Refer to Financial Note 10, “Income Taxes,” to the accompanying consolidated financial statements appearing in this Annual Report on Form 10-K for additional information.
The tax laws and regulations of the various countries where we have major operations are extremely complex and subject to varying interpretations. For example, we operate in various countries that collect value added taxes (“VAT”). The determination of the manner in which a VAT applies to our foreign operations is subject to varying interpretations arising from the complex nature of the tax laws and regulations. Although we believe that our historical tax positions are sound and consistent with applicable laws, regulations and existing precedent, there can be no assurance that these tax positions will not be challenged by relevant tax authorities or that we would be successful in any such challenge. Even if we are successful in maintaining our positions, we may incur significant expense in defending challenges to our tax positions by tax authorities that couldmight have a material impact on our financial position and results of operations.
In addition, as jurisdictions enact legislation to implement the recommendations of the recently concluded base erosion and profit shifting project undertaken by the Organization for Economic Cooperation and Development or as a result of the European Commission’s investigations into illegal state aid, changes to long-standing tax principles may result which could adversely impact our tax expense and cash flows.
Volatility and disruption to the global capital and credit markets may adversely affect our ability to access credit, our cost of credit and the financial soundness of our customers and suppliers.
Volatility and disruption in the global capital and credit markets, including the bankruptcy or restructuring of certain financial institutions, reduced lending activity by other financial institutions, or decreased liquidity and increased costs in the commercial paper market, may adversely affect the availability and cost of credit already arranged and the availability, terms and cost of credit in the future. Although we believe that our operating cash flow, financial assets, current access to capital and credit markets, including our existing credit facilities, will give us the ability to meet our financing needs for the foreseeable future, there can be no assurance that volatility and disruption in the global capital and credit markets will not impair our liquidity or increase our costs of borrowing.

Our business could also be negatively impacted if our customers or suppliers experience disruptions resulting from tighter capital and credit markets or a slowdown in the general economy. As a result, customers may modify, delay or cancel plans to purchase or implement our products or services and suppliers may increase their prices, reduce their output or change their terms of sale. Additionally, if customers’ or suppliers’ operating and financial performance deteriorates or if they are unable to make scheduled payments or obtain credit, customers may not be able to pay, or may delay payment of accounts receivable owed to us and suppliers may restrict credit, impose different payment terms or be unable to make payments due to us for fees, returned products or incentives. Any inability of customers to pay us for our products and services or any demands by suppliers for different payment terms, may have a materialmaterially adverse impact on our results ofbusiness operations, reputation, and cash flow.
Changes in accounting standards issued by the Financial Accounting Standards Board (“FASB”) or other standard-setting bodies may adversely affect our consolidated financial statements.
Our consolidated financial statements are subject to the application of U.S. GAAP, which is periodically revised and/or expanded. From time to time, we are required to adopt new or revised accounting standards issued by recognized authoritative bodies, including the FASB and the SEC. It is possible that future accounting standards we are required to adopt, such as the amended guidance for leases, may require changes to the current accounting treatment that we apply to our consolidated financial statements and may require us to make significant changes to our systems. Such changes could result in a material adverse impact on our financial position andor results of operations.
We could facemight experience significant liability if we withdraw from participation in oneproblems with information systems or more multiemployer pension plans in which we participate, or if one or more multiemployer plans in which we participate is underfunded.networks.
We participate in various multiemployer pension plans. Inrely on sophisticated information systems and networks to perform our business operations, such as to obtain, rapidly process, analyze and manage data that facilitate the event that we withdrawpurchase and distribution of thousands of inventory items from participation in one of these plans, then applicable law could require us to make additional cash contributions to the plans in installments. Our withdrawal liability for any multiemployer plan would depend on the extent of the plan’s funding of vested benefits. The multiemployer plans could have significant unfunded vested liabilities. Such underfunding may increase in the event other employersdistribution centers. If those information systems suffer errors, interruptions, or become insolvent or withdraw from the applicable plan or upon the inability or failure of withdrawing employers to pay their withdrawal liability. In addition, such underfunding may increase asunavailable, there might be a result of lower than expected returns on pension fund assets or other funding deficiencies. The occurrence of any of these events could have a materialmaterially adverse impact on our consolidatedbusiness operations, reputation, and our financial position or results of operationsoperations.
Our products or cash flows.services might not conform to specifications or perform as we intend.
We sell and provide services involving complex software and technology that may contain errors, especially when first introduced to market. Healthcare professionals delivering patient care tend to have heightened sensitivity to system and software errors. If our software and technology services are alleged to have contributed to faulty clinical decisions or injury to patients, we might be subject to claims or litigation by users of our software or services or their patients. Errors or failures might damage our reputation and negatively affect future sales. A failure of a system or software to conform to specifications might constitute a breach of warranty that could result in repair costs, contract termination, refunds of amounts previously paid or claims for damages. Any of these types of errors or failures might have a materially adverse impact on our reputation, business operations and our financial position or results of operations.

We might be impeded in providing customers online services and data access.
We provide remote services that involve hosting customer data and operating software on our own or third party systems. Our customers rely on their ability to access the systems and their data as needed. The networks and hosting systems are vulnerable to interruption or damage from sources beyond our control, such as power loss, telecommunications failures, fire, natural disasters, software and hardware failures and cyberattacks. If the timely delivery of medical care or other customer business requirements are impaired by data access, network or systems problems, we could be exposed to significant claims and reputational harm. Any such problems might have a materially adverse impact on our business operations and our financial position or results of operations.
We might not realize the expected benefits from our restructuring and business process initiatives.
From time to time, the CompanyWe may enter intoimplement restructuring, and business process initiatives. In April 2018, the Company announced a multi-year strategic growth initiative focused on creating innovative new solutions that improve patient care delivery and drive incremental profit growth. The initiative includes a comprehensive review of the Company’s operations and cost structure, designed to increase efficiency, accelerate execution and improve long-term performance. In March 2016, the Company also committed to a restructuring plan to lower its operating costs (“Cost Alignment Plan”). The Cost Alignment Plan primarily consists of a reduction in workforce andor other business process initiatives that will be substantially implemented priormight result in extraordinary charges and expenses, failures to the end of 2019. These types of initiatives could yieldachieve our desired objectives, or unintended consequences such as distraction of our management and employees, business disruption, attrition beyond any planned reduction in workforce, inability to attract or retain key personnel and reduced employee productivityproductivity. Any of these risks might have a materially adverse impact on our business operations and our financial position or results of operations.
We might be unable to successfully complete or integrate acquisitions or other business combinations.
Our growth strategy includes consummating acquisitions or other business combinations that either expand or complement our business. To fund acquisitions, we may require financing that may not be available on acceptable terms. We may not receive regulatory approvals needed to complete proposed transactions, or such approvals may be subject to delays or conditions that reduce transaction benefits. Achieving the desired outcomes of business combinations involves significant risks including: diverting management’s attention from other business operations; challenges with assimilating the acquired businesses, such as integration of operations and systems; failure or delay in realizing operating synergies; difficulty retaining key acquired company personnel; unanticipated accounting or financial systems issues with the acquired business, which might affect our internal controls over financial reporting; unanticipated compliance issues in the acquired business; challenges retaining customers of the acquired business; unanticipated expenses or charges to earnings, including depreciation and amortization or potential impairment charges; and risks of known and unknown assumed liabilities in the acquired business. Any of these risks could adversely affect our ability to achieve the anticipated benefits of an acquisition and might have a materially adverse impact on our business operations and our financial position or results of operations.
Exclusive forum provisions in our Bylaws could limit our stockholders’ ability to choose their preferred judicial forum for disputes with us or our directors, officers or employees.
Our amended and restated bylaws provide that, unless the Corporation consents in writing to the selection of an alternative forum, the sole and exclusive forum for specified legal actions is the Court of Chancery of the State of Delaware or the United States District Court for the District of Delaware if the Court of Chancery does not have or declines to accept jurisdiction (collectively, “Delaware Courts”). Current and former stockholders are deemed to have consented to the personal jurisdiction of the Delaware Courts in connection with any action to enforce that exclusive forum provision and to service of process in any such action. These provisions of the bylaws are not a waiver of, and do not relieve anyone of duties to comply with, federal securities laws including those specifying the exclusive jurisdiction of federal courts under the Exchange Act and concurrent jurisdiction of federal and state courts under the Securities Act. To the extent that these provisions of the bylaws limit a current or former stockholder’s ability to select a judicial forum other than the Delaware Courts, they might discourage the specified legal actions, might cause current or former stockholders to incur additional litigation-related expenses and might result in outcomes unfavorable to current or former stockholders. A court might determine that these provisions of the bylaws are inapplicable or unenforceable in any particular action, in which case we may incur additional litigation related expenses in such action, and the action may result in outcomes unfavorable to us, which could negativelyhave a materially adverse impact on our reputation, our business operations and our financial position or results of operations.

We might be adversely impacted by delays or other difficulties with divestitures.
When we decide to sell assets or a business, we may encounter difficulty in finding buyers or exit strategies on acceptable terms or in a timely manner, which could delay the achievement of our strategic objectives. After the disposition, we might experience greater dissynergies than expected, and the impact of the divestiture on our revenue or profit might be larger than we expected. We might have difficulties with pre-closing conditions such as regulatory and governmental approvals, which could delay or prevent the divestiture. We might have financial exposure in a divested business, such as through minority equity ownership, financial or performance guarantees, indemnities or other obligations, such that conditions outside of our control might negate the expected benefits of the disposition. Any of these risks could adversely affect our ability to achieve the anticipated benefits of a divestiture and might have a materially adverse impact on our business sales,operations and our financial condition andposition or results of operations. Moreover,
We might not realize the expected tax treatment from our restructuringsplit-off of Change Healthcare.
On March 10, 2020, the Company completed a separation of its interest in Change Healthcare LLC (“Change Healthcare JV”). The divestiture was effected through the split-off of PF2 SpinCo, Inc. (“SpinCo”), a wholly owned subsidiary of the Company that held all of the Company’s interest in the Change Healthcare JV, to certain of the Company’s stockholders through an exchange offer (the “Exchange Offer”), followed by a merger of SpinCo with and business process initiatives result in chargesinto Change Healthcare Inc. (“Change”), with Change surviving the merger (the “Merger” and, expenses that impact our operating results. We cannot guaranteetogether with the Exchange Offer, the “Transactions”). The Company received an opinion from outside legal counsel to the effect that the activities underTransactions qualified as generally tax-free transactions to the Company and its shareholders for U.S. federal income tax purposes. An opinion of legal counsel is not binding on the Internal Revenue Service (the “IRS”) or the courts, and the IRS or the courts may not agree with the intended tax-free treatment of the Transactions. In addition, the opinion could not be relied upon if certain assumptions, representations and undertakings upon which the opinion was based are materially inaccurate or incomplete, or are violated in any restructuringmaterial respect. If the intended tax-free treatment of the Transactions is not sustained, the Company and business initiative will resultits stockholders who participated in the desired efficienciesTransactions may be required to pay substantial U.S. federal income taxes. In connection with the Transactions, the Company, SpinCo, Change and estimated cost savings.

the Change Healthcare JV entered into the Tax Matters Agreement, which governs their respective rights, responsibilities and obligations with respect to tax liabilities and benefits, tax attributes, tax contests and other tax sharing regarding U.S. federal, state and local, and non-U.S. taxes, other tax matters and related tax returns. Under the Tax Matters Agreement, Change is required to indemnify the Company if the Transactions become taxable as a result of certain actions by Change or SpinCo, or as a result of certain changes in ownership of the stock of Change after the Merger. If Change does not honor its obligations to indemnify the Company, or if the Transactions fail to qualify for the intended tax-free treatment for reasons not related to a disqualifying action by Change or SpinCo, the resulting tax to the Company could have a significant adverse effect on our financial position or results of operations.
We may experience difficulties withmight be adversely impacted by outsourcing andor similar third-party relationships.
Our ability to conduct our business might be negatively impacted if we experience difficulties with outsourcing and managing similar third-party relationships. We outsource certain business and administrative functions and rely on third parties to perform certain services on our behalf. If we fail tobusiness and administrative functions for us. We might not adequately develop, implement and monitor our outsourcing strategies, such strategies prove to be ineffective or fail to providethese outsourced service providers, and we might not realize expected cost savings or our third-partyother benefits. Third-party services providers might fail to perform as anticipated, or we maymight experience unanticipated operational difficulties, andcompliance requirements or increased costs may adversely affect the results of our operations.

Moreover, we utilize contractors and employees located outside of the United Statesrelated to assist us in performing services or providing support for our customers. Certain of these resources may have access to personal information, including protected health information. Some of our customers have contractually limited or may seek to limitoutsourced services. For example, our ability to use our offshoreoutsourcing resources which may increase our costs due to concerns regarding potential misuse of this information. Further, Congress and a number of states have considered legislation that would restrict the transmission of personal information of United States residents offshore. Some proposals impose liability on healthcare businesses resulting from misuse or prohibited transmission of personal information to individuals or entities outside the United States and may require the prior consent of the identifiable patient. Congress also has considered establishing a private civil cause of action enabling an individual to recover damages sustained as a result of a violation of these proposed restrictions.

We may face risks associated withbe unsuccessful in retail pharmacy operations or maintaining profitability.
Our business strategy included expanding our retail expansion.

In recent years, we have expanded ourpharmacy operations. Our retail pharmacy operations through a number of acquisitions. As we expand our retail footprint, we may faceinvolve numerous risks, that are different from those we currently encounter. Our expansion into additional retail markets, such as those in Europe and Canada, could result in increased competitive, merchandising and distribution challenges.the following ones. We maymight encounter difficulties in attracting and retaining customers to our retail locations due to a lack of customer familiaritytheir unfamiliarity with our brands andor our lack of familiarityinexperience with local customer preferences and seasonal differencesmarket preferences. Competition from our retail pharmacy operations might strain relationships with our retail pharmacy customers. Consolidation of retail pharmacies with third party payers, expansion of large retail pharmacy networks, reductions in reimbursement rates, shifts in the market. Our ability to expand successfully will depend on acceptancemix of branded and generic pharmaceutical sales, and exclusion from preferred pharmacy networks can impair our retail store experience by customers, including our abilitypharmacy sales and profitability. Failure to design our stores in a manner that resonates locally and to offer the correct product assortment to appeal to consumers.

We might be harmed by large customer purchase reductions, payment defaults or contract non-renewal.
We derive a significant portion of our revenue from, and have a significant portion of our accounts receivable with, a small number of customers. At March 31, 2021, sales to our largest customer represented approximately 21% of our consolidated revenues and approximately 19% of our trade receivables, and those of our ten largest customers combined accounted for approximately 51% of our consolidated revenues and approximately 32% of our trade receivables. A material default in payment, reduction in purchases, or the loss of business from a large customer might have a materially adverse impact on our business operations and growth prospectsour financial position or results of operations.
Our contracts with government entities involve future funding and compliance risks.
Our contracts with government entities are subject to risks such as lack of funding and compliance with unique requirements. For example, government contract purchase obligations are typically subject to the availability of funding, which may be eliminated or reduced. In addition, the future volume of products or services purchased by a government customer is uncertain. Our government contracts might not be renewed or might be terminated for convenience with little or no prior notice. Government contracts typically expose us to higher potential liability than do other types of contracts. In addition, government contracts typically are subject to procurement laws that include socio-economic, employment practices, environmental protection, recordkeeping and accounting and other requirements. For example, our contracts with the U.S. government generally require us to comply with the Federal Acquisition Regulations, Procurement Integrity Act, Buy American Act, Trade Agreements Act, and other laws and regulations. We are subject to government audits, investigations and oversight proceedings. Government agencies routinely review and audit government contractors to determine whether they are complying with contractual and legal requirements. If we fail to comply with these requirements, or we fail an audit, we are subject to various sanctions such as monetary damages, criminal and civil penalties, termination of contracts and suspension or debarment from government contract work. These requirements complicate our business and increase our compliance burden. The occurrence of any of these risks could harm our reputation and might have a materially adverse impact on our business operations and our financial position or results of operations.
Our participation in vaccination distribution programs may materially affect our operating results, reputation, and business.
We participate as a distributor in government-sponsored vaccination programs, such as the U.S. government’s COVID-19 distribution program (“Federal COVID-19 Response”). We also provide supplies used for vaccine administration in the Federal COVID-19 Response. Our participation in such programs exposes us to various uncertainties. For example, the novel nature of the SARS-CoV‑2 virus and the broad scope of the ongoing COVID-19 vaccine distribution program introduce uncertainty about what volumes of products may become available for distribution by us, the effectiveness of vaccines, and the cost of distribution. Because of such uncertainties, our operating results may be subject to variability. Our participation in such programs also exposes us to various risks, including regulatory compliance, government oversight, dependence on government funding, contractual performance, litigation, security risks, and supply chain challenges. Any significant problems with our participation in such programs might have a materially adverse impact on our reputation and our business. Because of these risks and uncertainties our operating results may be materially adversely affected.higher or lower than our projections.

We might be harmed by changes in our relationships or contracts with suppliers.
We attempt to structure our pharmaceutical distribution agreements with manufacturers to ensure that we are appropriately and predictably compensated for the services we provide. Certain distribution agreements with manufacturers include pharmaceutical price inflation as a component of our compensation, and we cannot control the frequency or magnitude of pharmaceutical price changes. We might be unable to renew pharmaceutical distribution agreements with manufacturers in a timely and favorable manner. Any of these risks might have a materially adverse impact on our business operations and our financial position or results of operations.

We might infringe intellectual property rights or our intellectual property protections might be inadequate.
We believe that our products and services do not infringe the proprietary rights of third parties, but third parties have asserted infringement claims against us and may do so in the future. If a court were to hold that we infringed other’s rights, we might be required to pay substantial damages, develop non-infringing products or services, obtain a license, stop selling or using the infringing products or services, or incur other sanctions. We rely on trade secret, patent, copyright and trademark laws, nondisclosure obligations and other contractual provisions and technical measures to protect our proprietary rights in our products and solutions. We might initiate costly and time-consuming litigation to protect our trade secrets, to enforce our patent, copyright and trademark rights and to determine the scope and validity of the proprietary rights of others. Our intellectual property protection efforts might be inadequate to protect our rights. Our competitors might develop non-infringing products or services equivalent or superior to ours. Any of these risks might have a materially adverse impact on our business operations and our financial position or results of operations.
We might be unable to successfully recruit and retain qualified employees.
Our retailability to attract, engage, develop and retain qualified and experienced employees, including key executives and other talent, is essential for us to meet our objectives. We compete with many other businesses to attract and retain employees. Competition among potential employers might result in increased salaries, benefits or other employee-related costs, or in our failure to recruit and retain employees. We may experience sudden loss of key personnel due to a variety of causes, such as illness, and must adequately plan for succession of key management roles. Employees might not successfully transition into new roles. Any of these risks might have a materially adverse impact on our business operations and our financial position or results of operations.
Industry and Economic Risks
We might be adversely impacted by healthcare reform such as changes in pricing and reimbursement models.
Many of our products and services are designed and intended to function within the structure of current healthcare financing and reimbursement systems. The healthcare industry and related government programs are changing. Some of these changes increase our risks and create uncertainties for our business.
For example, some changes in reimbursement methodologies (including government rates) for pharmaceuticals, medical treatments and related services reduce profit margins for us and our customers and impose new legal requirements on healthcare providers. Those changes have included cuts in Medicare and Medicaid reimbursement levels, changes in the basis for payments, shifting away from fee-for-service and towards value-based payments and risk-sharing models, and increases in the use of managed care.
In the U.S., the Patient Protection and Affordable Care Act (“ACA”) significantly expanded health insurance coverage to uninsured Americans and changed the way healthcare is financed by both governmental and private payers. There are continued efforts to challenge the ACA. There are also efforts to broaden healthcare coverage. U.S. lawmakers also have explored proposals to reduce drug prices, including requiring price transparency and drug importation measures. These proposals might result in significant changes in the pharmaceutical value chain as manufacturers, PBM, managed care organizations and other industry stakeholders look to implement new transactional flows and adapt their business models.
Provincial governments in Canada that provide partial funding for the purchase of pharmaceuticals and independently regulate the sale and reimbursement of drugs have sought to reduce the costs of publicly funded health programs. For example, provincial governments have taken steps to reduce consumer prices for generic pharmaceuticals and, in some provinces, change professional allowances paid to pharmacists by generic manufacturers.
Many European governments provide or subsidize healthcare to consumers and regulate pharmaceutical prices, patient eligibility and reimbursement levels in order to control government healthcare system costs. Some European governments have implemented or are considering austerity measures to reduce healthcare spending. These measures exert pressure on the pricing and reimbursement timelines for pharmaceuticals and may cause our customers to purchase fewer of our products and services or influence us to reduce prices.

Although there is substantial uncertainty about the likelihood, timing and results of these health reform efforts, their implementation might have a materially adverse impact on our business operations and our financial position or results of operations.
We might be adversely impacted by competition and industry consolidation.
Our businesses face a highly competitive global environment with strong competition from international, national, regional and local full-line, short-line and specialty distributors, service merchandisers, self-warehousing chain drug stores, manufacturers engaged in direct distribution, third-party logistics companies and large payer organizations. In addition, our businesses face competition from various other service providers and from pharmaceutical and other healthcare manufacturers as well as other potential customers, which may require additionalfrom time-to-time decide to develop, for their own internal needs, supply management time and attention. Failurecapabilities that might otherwise be provided by our businesses. Due to properly supervise the operation and maintain the consistencyconsolidation, a few large suppliers control a significant share of the pharmaceuticals market. This concentration reduces our ability to negotiate favorable terms with suppliers and causes us to depend on a smaller number of suppliers. Many of our customers, including healthcare organizations, have consolidated and have greater power to negotiate favorable prices. Consolidation by our customers, suppliers and competitors might reduce the number of market participants and give the remaining enterprises greater bargaining power, which might lead to erosion in our profit margin. Consolidation might increase counter-party credit risk because credit purchases increase for fewer market participants. These competitive pressures and industry consolidation might have a materially adverse impact on our business operations and our financial position or results of operations.
We might be adversely impacted by changes or disruptions in product supply.
Our supply arrangements might be interrupted or adversely affected by a variety of causes over which we have no control, such as export controls or trade sanctions, labor disputes, unavailability of key manufacturing sites, inability to procure raw materials, quality control concerns, ethical sourcing issues, supplier’s financial distress, natural disasters, civil unrest or acts of war. Our inventory might be requisitioned, diverted or allocated by government order such as under emergency, disaster and civil defense declarations. For example, government actions in response to the COVID-19 pandemic affect our supply allocation, and those and our own allocation decisions can impact our customer relationships. Changes in the healthcare industry’s or our suppliers’ pricing, selling, inventory, distribution or supply policies or practices could significantly reduce our revenues and net income. We might experience disruptions in our supply of higher margin pharmaceuticals, including generic pharmaceuticals. Any of these changes or disruptions might have a materially adverse impact on our business operations and our financial position or results of operations.
We might be adversely impacted as a result of our distribution of generic pharmaceuticals.
Our generic pharmaceuticals distribution business is subject to pricing risks. We might be adversely impacted if our ClarusONE generic pharmaceutical sourcing joint venture with Walmart, Inc. is unsuccessful or experiences margins declines. Generic drug manufacturers often offer a generic version of branded pharmaceuticals while they challenge the validity or enforceability branded pharmaceutical patents. The patent holder might assert infringement claims against us for distributing those retail storesgeneric versions and the generic drug manufactures may not fully indemnify us against such claims. These risks, as well as changes in the availability, pricing volatility, reimbursement rates for generic drugs, or significant changes in the nature, frequency or magnitude of generic pharmaceutical launches, might have a materially adverse impact on our business operations and our financial position or results of operations.
We might be adversely impacted by an economic slowdown or recession.
An economic slowdown or recession affecting our businesses in one or more regions could reduce the prices our customers are able or willing to pay for our products and services and the volume of their purchases. This risk is increased by the COVID-19 pandemic. Any economic slowdown or recession might have a materially adverse impact on our business operations and our financial position or results of operations.

Disruption or other changes in capital and credit markets might impede access to credit and increase borrowing costs for us and our customers and suppliers and might impair the financial soundness of our customers and suppliers.
Volatility and disruption in global capital and credit markets, including the bankruptcy or restructuring of certain financial institutions, reduced lending activity by financial institutions, or decreased liquidity and increased costs in the commercial paper market, might adversely affect our borrowing ability and cost of borrowing. We generally sell our products and services under short-term unsecured credit arrangements. An adverse change in general economic conditions or access to capital might cause our customers to reduce their purchases from us, or delay or fail paying amounts owed to us. Suppliers might increase their prices, reduce their output or change their terms of sale due to limited availability of credit. Suppliers might be unable to make payments due to us for fees, returned products or incentives. These risks are increased by the COVID-19 pandemic. Interest rate increases or changes in capital market conditions might impede our or our customers’ or suppliers’ ability or cost to obtain credit. Any of these risks might have a material adverse impact on our business operations and our financial position or results of operations.
We may have difficulties in sourcing or selling products due to a variety of causes.
We might experience difficulties and delays in sourcing and selling products due to a variety of causes, such as: difficulties in complying with the legal requirements for export or import of pharmaceuticals or components; suppliers’ failure to satisfy production demand; manufacturing or supply problems such as inadequate resources; and real or perceived quality issues. Difficulties in product manufacturing or access to raw materials could result in losssupplier production shutdowns, product shortages and other supply disruptions. The FDA banned certain manufacturers from selling raw materials and drug ingredients in the U.S. due to quality issues. The COVID-19 pandemic adversely affects the availability of customerssome products, resulting in product allocation and potentiallydelivery delays. Any of these risks might have a materially adverse impact on our business operations and our financial position or results of operations.
We might be adversely impacted by tax legislation or challenges to our tax positions.
We are subject to the tax laws in the U.S. at the federal, state and local government levels and to the tax laws of many other jurisdictions in which we operate or sell products or services. Tax laws might change in ways that adversely affect our tax positions, effective tax rate and cash flow. The tax laws are extremely complex and subject to varying interpretations. We are subject to tax examinations in various jurisdictions that might assess additional tax liabilities against us. Our tax reporting positions might be challenged by relevant tax authorities, we might incur significant expense in our efforts to defend those challenges, and we might be unsuccessful in those efforts. Developments in examinations and challenges might materially change our provision for taxes in the affected periods and might differ materially from our historical tax accruals. Any of these risks might have a materially adverse impact on our business operations, our cash flows and our financial position or results of operations.

We might be adversely impacted by the Brexit withdrawal of the United Kingdom from the European Union.
We have operations in the U.K. and the European Union (“E.U.”) and face risks associated with the uncertainty and potential disruptions that might follow the U.K. withdrawing from the European Union (“Brexit”). Brexit could adversely affect political, regulatory, economic or market conditions and contribute to instability in global political institutions, regulatory agencies and financial markets. For example, we might experience volatility in exchange rates and interest rates and changes in laws regulating our U.K. operations. Customers might reduce purchases due to the uncertainty caused by Brexit. Any of these risks might have a materially adverse impact on our business operations and our financial position or results of operations.
We might be adversely impacted by fluctuations in foreign currency exchange rates.
We conduct our business in various currencies, including the U.S. dollar, euro, British pound sterling and Canadian dollar. Changes in foreign currency exchange rates could reduce our revenues, increase our costs or otherwise adversely affect our financial results reported in U.S. dollars. For example, we are exposed to transactional currency exchange risk due to our import and export of products that are purchased or sold in currencies other than the U.S. dollar. We also have currency exchange risk due to intercompany loans denominated in various currencies. The COVID-19 pandemic has affected and might increase currency exchange rate volatility. We may from time to time enter into foreign currency contracts, foreign currency borrowings or other techniques intended to hedge a portion of our foreign currency exchange rate risks. These hedging activities may not completely offset the adverse financial effects of unfavorable movements in foreign currency exchange rates during the time the hedges are in place. Any of these risks might have a materially adverse impact on our business operations and our financial position or results of operations.

General Risk Factors
We might be adversely impacted by events outside of our control, such as widespread public health issues, natural disasters, political events and other catastrophic events.
We might be adversely affected by events outside of our control, including: widespread public health issues, such as epidemic or pandemic infectious diseases; natural disasters such as earthquakes, floods or severe weather; political events such as terrorism, military conflicts and trade wars; and other catastrophic events. These events can disrupt operations for us, our suppliers, our vendors, and our customers. For example, in February 2021, a severe winter storm affecting the United States temporarily impacted our distribution business operations, primarily in Texas. They might affect consumer confidence levels and spending. In response to these events, we might suspend operations, implement extraordinary procedures, seek alternate sources for product supply, or suffer consequences that are unexpected and difficult to mitigate. In particular, the rapid and widespread transmission of the SARS-CoV-2 novel coronavirus beginning in late 2019 impacts us in significant ways. For example, to mitigate the spread of the COVID-19 disease caused by SARS-CoV-2, we implemented travel restrictions and remote working arrangements for most of our employees in order to minimize physical contact, and we implemented additional sanitation and personal protection measures in our warehouse, retail pharmacy and delivery operations. These measures might not fully mitigate COVID-19 risks to our workforce and we could experience unusual levels of absenteeism that might impair operations and delay delivery of products. The COVID-19 pandemic affects product manufacturing, supply and transport availability and cost. The pandemic reduces demand for some products due to delays or cancellations of elective medical procedures, consumer self-isolation and business closures, among other reasons. The COVID-19 pandemic influences shortages of some products, with product allocation resulting in delivery delays for customers. The ongoing impacts of the pandemic might cause a general economic slowdown or recession in one or more markets, disruptions and volatility in global capital markets and other broad and adverse effects on the economy, business conditions, commercial activity and the healthcare industry. The pandemic might impact our business operation, financial position and results of operation in unpredictable ways that depend on highly uncertain future developments, such as determining the effectiveness of current or future government actions to address the public health or economic impacts of the pandemic. Any of these risks might have a materially adverse impact on our business operations and our financial position or results of operations.
We may be unableadversely affected by global climate change or by legal, regulatory or market responses to keep existing retail store locationssuch change.
The long-term effects of climate change are difficult to predict and may be widespread. The impacts may include physical risks (such as rising sea levels or open new retail locationsfrequency and severity of extreme weather conditions), social and human effects (such as population dislocations or harm to health and well-being), compliance costs and transition risks (such as regulatory or technology changes) and other adverse effects. The effects could impair, for example, the availability and cost of certain products, commodities and energy (including utilities), which in desirable places, whichturn may impact our ability to procure goods or services required for the operation of our business at the quantities and levels we require. We bear losses incurred as a result of, for example, physical damage to or destruction of our facilities (such as distribution or fulfillment centers), loss or spoilage of inventory, and business interruption due to weather events that may be attributable to climate change. These events and impacts could materially adversely affect our business operations, financial position or results of operation.
We might be adversely impacted by changes in accounting standards.
Our consolidated financial statements are subject to the application of U.S. GAAP, which periodically is revised or reinterpreted. From time to time, we are required to adopt new or revised accounting standards issued by recognized authoritative bodies, including the Financial Accounting Standards Board (“FASB”) and the SEC. It is possible that future accounting standards may require changes to the accounting treatment in our consolidated financial statements and may require us to make significant changes to our financial systems. Such changes might have a materially adverse impact on our financial position or results of operations.

We may be unable to keep existing retail locations or open new retail locations in desirable places in the future. We compete with other retailers and businesses for suitable retail locations. Local land use, local zoning issues, environmental regulations and other regulations may affect our ability to find suitable retail locations and also influence the cost of leasing or buying them. We also may have difficulty negotiating real estate leases for new stores, renewing real estate leases for existing stores or negotiating purchase agreements for new sites on acceptable terms. In addition, construction, environmental, zoning and real estate delays may negatively affect retail location openings and increase costs and capital expenditures. If we are unable to keep up our existing retail store locations or open new retail store locations in desirable places and on favorable terms, our results of operations could be materially adversely affected.Item 1B.    Unresolved Staff Comments.

During 2016, we completed the May 2015 share repurchase authorization. At March 31, 2016, $1.0 billion remained available for future authorized repurchases of the Company’s common stock under the October 2015 authorization.
In 2016, we retired 115.5 million or $7.8 billion of the Company’sour treasury shares previously repurchased. Under the applicable state law, these shares resume the status of authorized and unissued shares upon retirement. In accordance with our accounting policy, we allocate any excess of share repurchase price over par value between additional paid-in capital and retained earnings. Accordingly, our retained earnings and additional paid-in capital were reduced by $6.4 billion and $1.5 billion during 2016.
In October 2016, the Board authorized the repurchase of up to $4.0 billion of the Company’s common stock.

As of March 31, 2018, we completed and received a total of 1.5 million shares under the June 2017 ASR program and a total of 2.7 million shares under the August 2017 ASR program. In addition, we received 2.5 million shares representing the initial number of shares due in March 2018 and an additional 0.5 million shares in April 2018 under the March 2018 ASR program. The total number of shares to be ultimately repurchased by the Company under the March 2018 ASR program will be determined at the completion of the program based on the average daily volume-weighted average price of the Company’s common stockrespectively, during this program, less a discount. The program is anticipated to be completed during the first quarter of 2019. The total authorization outstanding for repurchase of the Company’s common stock was $1.1 billion at March 31, 2018.

Overview of Our Business:
We conduct our business through twoare a global leader in healthcare supply chain management solutions, retail pharmacy, community oncology and specialty care, and healthcare information solutions. We partner with life sciences companies, manufacturers, providers, pharmacies, governments, and other healthcare organizations to help provide the right medicines, medical products, and healthcare services to the right patients at the right time, safely, and cost-effectively.
We implemented a new segment reporting structure commencing with the second quarter of 2021, which resulted in four reportable segments: McKesson DistributionU.S. Pharmaceutical, International, Medical-Surgical Solutions, and Prescription Technology Solutions (“MDS”RxTS”). Other, for retrospective periods presented, consists of our equity method investment in Change Healthcare LLC (“Change Healthcare JV”), which was split-off from McKesson in the fourth quarter of 2020. All prior segment information has been recast to reflect our new segment structure and McKesson Technology Solutions.current period presentation. Our organizational structure also includes Corporate, which consists of income and expenses associated with administrative functions and projects, and the results of certain investments. The factors for determining the reportable segments include the manner in which management evaluates the performance of the Company combined with the nature of individual business activities. We evaluate the performance of our operating segments on a number of measures, including revenues and operating profit before interest expense and income taxes.
The following summarizes our four reportable segments and the changes made to our reporting structure commencing in the second quarter of 2021. Refer to Financial Note 28,22, “Segments of Business,” to the accompanying consolidated financial statements appearingincluded in this Annual Report on Form 10-K for a description of thesefurther information regarding our reportable segments.

U.S. Pharmaceutical, previously the U.S. Pharmaceutical and Specialty Solutions reportable segment, continues to distribute branded, generic, specialty, biosimilar, and over-the-counter pharmaceutical drugs and other healthcare-related products. This segment also provides practice management, technology, clinical support, and business solutions to community-based oncology and other specialty practices. In addition, the segment sells financial, operational, and clinical solutions to pharmacies (retail, hospital, alternate site) and provides consulting, outsourcing, technological, and other services.

International is a new reportable segment that includes our operations in Europe and Canada, bringing together non-U.S.-based drug distribution services, specialty pharmacy, retail, and infusion care services. McKesson Europe was previously reflected as the European Pharmaceutical Solutions reportable segment and McKesson Canada was previously included in Other.
Medical-Surgical Solutions provides medical-surgical supply distribution, logistics, and other services to healthcare providers in the United States (“U.S.”) and was unaffected by the segment realignment.
RxTS is a new reportable segment that brings together existing businesses, including CoverMyMeds, RelayHealth, RxCrossroads, and McKesson Prescription Automation, including Multi-Client Central Fill as a Service, to serve our biopharma and life sciences partners and patients.

FINANCIAL REVIEW (Continued)



Executive Summary:
The following summary provides highlights and key factors that impacted our business, operating results, financial condition, and liquidity for the year ended March 31, 2021.
Coronavirus disease 2019 (“COVID-19”) impacted our results of operations for the year ended March 31, 2021. Following the declaration of COVID-19 as a global pandemic by the World Health Organization (“WHO”) on March 11, 2020, there was a temporary increase in demand for pharmaceuticals across our businesses. Subsequently, pharmaceutical distribution volumes decreased during the first quarter as a result of the weakened and uncertain global economic environment and COVID-19 restrictions, including government shutdowns and shelter-in-place orders. The recovery from the COVID-19 pandemic continued to fluctuate throughout our fiscal year. We benefited from demand for COVID-19 tests, favorable contributions from our vaccine and related ancillary supply kit distribution programs as discussed further below, and savings from reduced travel and meetings throughout 2021;
We expanded our existing contractual relationship with the Centers for Disease Control and Prevention (“CDC”) through an amendment to our existing Vaccines for Children Program contract to support the U.S. government as a centralized distributor of COVID-19 vaccines and ancillary supplies needed to administer vaccines. We have also partnered with the Department of Health and Human Services (“HHS”) and Pfizer to manage the assembly and distribution of the ancillary supplies needed to administer COVID-19 vaccines;
In December 2020, we began distributing certain COVID-19 vaccines under the direction of the CDC. Through the end of the fiscal year, we had distributed approximately 100 million of COVID-19 vaccine doses. For a more in-depth discussion of how COVID-19 impacted our business, operations, and outlook, refer to the COVID-19 section of "Trends and Uncertainties" included below;
Revenues of $238.2 billion, reflects a 3% increase from the prior year primarily in our U.S. Pharmaceutical segment driven by market growth;
Gross profit increased 1% from the prior year primarily in our Medical-Surgical Solutions segment driven by sales of COVID-19 tests;
Total operating expenses in 2021 includes the following:
a charge of $8.1 billion related to our estimated liability for opioid-related claims as further described in the Opioid-Related Litigation and Claims section of “Trends and Uncertainties” included below; and
charges of $115 million to impair certain long-lived assets within our International segment; partially offset by
a net gain of $131 million recorded in connection with insurance proceeds received from the settlement of the shareholder derivative action related to our controlled substances monitoring program;
Other income, net in 2021 includes net gains of $133 million related to our equity investments;
Diluted loss per common share from continuing operations attributable to McKesson Corporation in 2021 of $28.26 reflects the aforementioned items, net of any respective tax impacts, and a lower share count compared to the prior year driven largely by the separation of our investment in Change Healthcare JV on March 10, 2020;
On November 1, 2020, we completed the contribution of our German pharmaceutical wholesale business to a newly formed joint venture with Walgreens Boots Alliance (“WBA”) in which we have a 30% ownership interest;
On December 3, 2020, we completed a public offering of 0.90% Notes due December 3, 2025 (the “2025 Notes”) in a principal amount of $500 million and repaid $1.0 billion of long-term debt in 2021. Refer to Financial Note 13, “Debt and Financing Activities,” to the accompanying consolidated financial statements included in this Annual Report on Form 10-K for more information;
We returned $1.0 billion of cash to shareholders through $770 million of common stock repurchases, including the value of equity awards surrendered for tax withholding, and $276 million of dividend payments during 2021. On July 29, 2020, we raised our quarterly dividend from $0.41 to $0.42 per common share; and
In January 2021, our Board of Directors (the “Board”) approved an increase of $2.0 billion for the authorized share repurchase of McKesson’s common stock.

Trends and Uncertainties:
COVID-19
In December 2019, a novel strain of coronavirus, which causes the infectious disease known as COVID-19, was reported in Wuhan, China. The WHO declared COVID-19 a “Public Health Emergency of International Concern” on January 30, 2020 and a global pandemic on March 11, 2020.
We continue to evaluate the nature and extent of the impacts COVID-19 has on our business and operations. The pandemic developed rapidly during our fourth quarter of 2020 and continued to evolve throughout 2021. Infection rates varied throughout our fiscal year, peaking in January 2021. A significant number of new COVID-19 cases continue to be reported, particularly in the U.S. These also include cases from new and emerging COVID-19 variants, which could have the potential to be more severe, spread more easily, require different treatments, or change the effectiveness of current vaccines. However, vaccines which have met the U.S. Food and Drug Administration’s (“FDA’s”) standards for safety, effectiveness, and manufacturing quality needed to support Emergency Use Authorization (“EUA”), are currently being administered across the country, as further discussed below. As of March 31, 2021, nearly 154 million doses of COVID-19 vaccines have been administered in the U.S. according to the CDC. The full extent to which COVID-19 will impact us depends on many factors and future developments, which are described at the end of this COVID-19 section.
In response to the COVID-19 pandemic, federal, state, and local government directives and policies have been put in place in the U.S. to enhance availability of medications and supplies to meet the increased demand, assist front-line healthcare providers, manage public health concerns by creating social distancing, and address the economic impacts, including sharply reduced business activity, increased unemployment, and overall uncertainty presented by this healthcare emergency. Similar governmental actions have occurred in Canada and Europe, the timing of which has varied across geographies. In December 2020, the FDA issued an EUA for the Pfizer-BioNTech COVID-19 vaccine manufactured by Pfizer, Inc. (“Pfizer Vaccine”) and the Moderna COVID-19 vaccine manufactured by ModernaTX, Inc. (“Moderna Vaccine”) to be distributed in the U.S. These authorizations were followed by an EUA for the Janssen COVID-19 vaccine manufactured by Janssen Biotech Inc., a Janssen pharmaceutical company of Johnson & Johnson, (“Janssen Vaccine”) in February 2021. Government-coordinated administrative or allocation decisions at the federal, state, and local levels may cause variability in the timing and volume of COVID-19 vaccine distribution and administration activities. Our role in the distribution of COVID-19 vaccines in the U.S. as well as the assembly and distribution of related ancillary supply kits is discussed further below. Similar COVID-19 vaccine authorizations have occurred in Canada and Europe. McKesson Canada’s corporately owned retail pharmacy chain, Rexall, as well as independent pharmacy banners are supporting Canada’s vaccination efforts. McKesson Europe is also playing a role in helping support governments and public health entities in not only distributing COVID-19 vaccines across several European countries, but administering them in pharmacies as well.
As a global leader in healthcare supply chain management solutions, retail pharmacy, community oncology and specialty care, and healthcare information solutions, we are well positioned to respond to the COVID-19 pandemic in the U.S., Canada, and Europe. We have worked and continue to work closely with national and local governments, agencies, and industry partners to ensure that available supplies, including personal protective equipment (“PPE”), and medicine reach our customers and patients.

Our Response to COVID-19 in the Workplace
During this unprecedented time, we are committed in continuing to supply our customers and protect the safety of our employees. The various responses we put in place to mitigate the impact of COVID-19 on our business operations, including telecommuting and work-from-home policies, restricted travel, employee support programs, and enhanced safety measures, are intended to limit employee exposure to the virus that causes COVID-19. We expanded employee medical benefits covering COVID-19 related visits, treatments, and testing as well as expanded telehealth options to protect employee safety. We provided further support including additional emergency leave and an internal paid time off donation platform for employees impacted by COVID-19. For employees whose roles require presence at our facilities, we enhanced safety by promoting the practice of social distancing, providing reminders to wash or disinfect hands and avoid unnecessary face touching, making face masks available, placing hand sanitizers within our operating environments, and periodically cleaning and disinfecting our facilities. For employees whose roles do not require presence at our facilities, we added technology resources to support their working remotely. These responses were initially put in place during our fourth quarter of 2020. During the second quarter of 2021, we also implemented on-site workplace temperature screening as we continue to adapt our health and safety practices in response to the COVID-19 pandemic. When working in frozen vaccine storage environments, employees are provided with protective gear, including special clothing, gloves, and facial gear. These steps to protect employee safety have resulted in limited disruption from COVID-19 to our normal business operations, productivity trends, and have not materially impacted our operating expenses or operating margins.
We have evaluated the impact of our telecommuting and work-from-home policies on our system of internal controls and we have concluded that these policies did not have a material effect on our internal control over financial reporting during the year ended March 31, 2021. We also took various actions to mitigate the impact of COVID-19 on our results from operations through cost-containment and payroll-related expenses.
Trends in our Business
At the onset of the COVID-19 pandemic late in our fourth quarter of 2020, we experienced higher pharmaceutical distribution volumes and increased retail pharmacy foot traffic as our customers increased supplies on hand in March, which drove unfavorability in our results of operations when comparing 2021 versus 2020.
During the first quarter of 2021, we experienced growth in pharmaceutical distribution and specialty drug volumes at a lower rate in the U.S., while pharmaceutical distribution volumes decreased in Europe and Canada due to the COVID-19 pandemic, as compared to the same prior year period. Specialty drug volumes increased, but were negatively impacted by lower demand for elective specialty drugs, as compared to the same prior year period. We also experienced decreased demand for primary care medical-surgical supplies due to deferrals in elective procedures in hospitals and surgery centers as well as decreased traffic and closures of doctors’ offices, which was partially offset by demand for PPE and COVID-19 tests. Additionally, the decreased traffic in doctors’ offices and general shelter-in-place guidance by governmental authorities negatively impacted retail pharmacy foot traffic in both Europe and Canada.
While we experienced improvements in prescription volumes and primary care patient visits during our second quarter of 2021, the impact and recovery of COVID-19 for the second half of our fiscal year was non-linear and tracked with patient mobility. We also saw increased demand for COVID-19 tests and continued sales of PPE throughout the year in our Medical-Surgical Solutions segment partially offset by the impacts of social distancing measures which resulted in a less severe cough, cold, and flu season, savings for reduced travel and meetings across the enterprise, as well as improvements of retail pharmacy foot traffic in Europe and Canada. The vaccine and related ancillary kit distribution in the U.S. favorably impacted our results in the second half of fiscal 2021 as further discussed below.

Our Role in the Distribution of COVID-19 Vaccines and Ancillary Supply Kits
On August 14, 2020, we expanded our contractual relationship with the CDC through an amendment to our existing Vaccines for Children Program contract for the distribution of certain COVID-19 vaccines. The COVID-19 vaccine distribution agreement with the CDC was finalized during the third quarter of 2021. We support the U.S. government as a centralized distributor of COVID-19 vaccines and ancillary supplies needed to administer vaccines. In the centralized model, the U.S. government directs us on the distribution of the vaccines and related supplies to point-of-care sites across the country. We make no decisions on where products are to be distributed nor how the products are allocated between the various provider sites and ultimately administered to the individuals receiving a vaccine. We utilize our expertise and capabilities to support the CDC’s efforts to vaccinate everyone in the U.S. who wants to receive a COVID-19 vaccine. The CDC and McKesson collaborated similarly in response to the 2009 H1N1 pandemic.
In December 2020, we began distributing the Moderna Vaccine in the U.S. and in March 2021, we began distributing the Janssen Vaccine. We may distribute other future authorized COVID-19 vaccines that are refrigerated or frozen. Ancillary supply kits may be shipped either together with the Moderna Vaccine and Janssen Vaccine or in advance of the vaccines. The results of operations related to our vaccine distribution are reflected in our U.S. Pharmaceutical segment. The Pfizer Vaccine, which is ultra-frozen, is not being distributed by McKesson, although we are providing ancillary supplies needed for its administration.
On September 23, 2020, we announced our contract with the HHS under which our Medical-Surgical Solutions segment manages the assembly and distribution of ancillary supply kits needed to administer COVID-19 vaccines, including sourcing some of those supplies. We also have an agreement with Pfizer to assemble and distribute ancillary supply kits needed to administer that particular COVID-19 vaccine. Ancillary supply kits include alcohol prep pads, face shields, surgical masks, needles and syringes, and other vaccine administration items. For the Pfizer Vaccine, ancillary supply kits also include the diluent needed to administer the ultra-frozen vaccine. We began assembling the ancillary supply kits in September 2020 in preparation for vaccine authorization and subsequent distribution. Ancillary supply kits to administer the Pfizer Vaccine are shipped directly to point-of-care sites, and all other ancillary supply kits are shipped to our dedicated vaccine distribution centers. The results of operations for the kitting and distribution of ancillary supplies are reflected in our Medical-Surgical Solutions segment. The future financial impact of the arrangements with the CDC and HHS depend on numerous uncertainties, which are described at the end of this COVID-19 section.
To manage the COVID-19 vaccine and ancillary supply kit distribution, we have set up special, dedicated vaccine distribution centers that include large-scale, custom freezers and refrigerators to safely store and process millions of vaccine doses. These facilities can scale to meet the demand of increasing volumes of vaccines being manufactured. We have also set up distribution centers for kitting and inventory management as part of our contract with the HHS. We are working with delivery partners to manage the delivery of vaccines and ancillary supply kits from our centralized vaccine distribution centers to point-of-care destinations as directed by the CDC. The capital expenditures we made during 2021 to prepare for vaccine and ancillary supply kit distribution were not material to our financial condition or liquidity.

Impact to our Results of Operations, Financial Condition, and Liquidity
For the year ended March 31, 2021, the demand for COVID-19 tests, the year over year impact from PPE and other related products, net of inventory charges, as well as the kitting and distribution of ancillary supplies for COVID-19 vaccines in our Medical-Surgical Solutions segment contributed approximately 20% in segment revenues and segment operating profit. Additionally, the distribution of COVID-19 vaccines in our U.S. Pharmaceutical segment contributed approximately 2% in segment operating profit for the year ended March 31, 2021. During our fourth quarter of 2020, we experienced a temporary increase in demand for pharmaceuticals. Subsequently, during the first quarter, we had lower pharmaceutical volumes, specialty drug volumes, and patient care visits that negatively impacted our consolidated revenues and income (loss) from continuing operations before income taxes for the year ended March 31, 2021. During the year ended March 31, 2021, selling, distribution, general, and administrative expenses decreased as a result of the pandemic, largely due to savings from restricted travel and decreased meetings. The favorable reduction in selling, distribution, general, and administrative expenses was partially offset by increased costs of transport, costs for enhanced procedures to sanitize operating facilities, and costs of providing PPE and other related products for employee use. Additionally, increased costs for certain PPE compressed our margins. Certain PPE items held for resale were valued in our inventory at costs that were inflated by earlier COVID-19 pandemic demand levels. That inventory valuation, if not supported by market resale prices, may be written down to net realizable value. We may also write-off inventory due to decreased customer demand and excess inventory. During the year ended March 31, 2021, we recorded charges totaling $136 million in cost of sales on certain PPE and other related products due to inventory impairments and excess inventory in our Medical-Surgical Solutions segment. Although market price volatility and changes to anticipated customer demand may require additional write-downs in future periods, we are taking measures to mitigate such risk. Overall, these COVID-19 related items had a net favorable impact on consolidated income (loss) from continuing operations before income taxes for the year ended March 31, 2021 compared to the prior year. Impacts to future periods due to COVID-19 may differ based on future developments, which is described at the end of this COVID-19 section.
We were able to maintain appropriate labor and overall vendor supply levels during the year ended March 31, 2021. Our inventory levels have fluctuated in response to supply availability and customer demand patterns for certain products, with varying inventory level impacts depending on the specific product within our portfolio. We collaborated closely with the federal government and other healthcare stakeholders to source more critical PPE to the U.S. This collaboration expedited the shipment of critical medical supplies to areas hit hardest by COVID-19, as identified by the Federal Emergency Management Agency. As our supply levels improve, and the federal government evolves guidance on the prioritization of providers or geographic markets, we will continue to adapt our distribution policies.
On March 27, 2020, the U.S. government enacted the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”) to address the economic impact of the COVID-19 pandemic. Among other things, the CARES Act provides certain changes to tax laws and includes provisions to provide relief for citizens, companies, healthcare providers and patients, and others. We have deferred certain employer payroll taxes and continue to monitor the potential impact of other tax legislation changes as result of the CARES Act, including refundable payroll tax credits on certain qualified wages. We anticipate changes due to the CARES Act in the timing of certain cash flows, with no material impact to our financial results for the year ended March 31, 2021. On December 27, 2020, the U.S. government enacted the Consolidated Appropriations Act, 2021 (the “CA Act”), which enhances and expands certain provisions of the CARES Act. The CA Act did not have a material impact on our financial condition, results of operations, or liquidity for the year ended March 31, 2021 nor do we currently expect a material impact on our future financial results.
Our consolidated balance sheets and ability to maintain financial liquidity remains strong. We have experienced no material impacts to our liquidity or net working capital due to the COVID-19 pandemic. We are monitoring our customers closely for changes to their timing of payments or ability to pay amounts owed to us as a result of COVID-19 pandemic impacts to their businesses. We remain well-capitalized with access to liquidity from our revolving credit facility. Long-term debt markets and commercial paper markets, our primary sources of capital after cash flow from operations, have remained open and accessible to us during the COVID-19 pandemic. At March 31, 2021, we were in compliance with all debt covenants, and believe we have the ability to continue to meet our debt covenants in the future.

Impact to our Supply Chain
We also continue to monitor the COVID-19 pandemic impacts on our supply chain. Although the availability of various products is dependent on our suppliers, their locations, and the extent to which they are impacted by the COVID-19 pandemic, we are proactively working with manufacturers, industry partners, and government agencies to meet the needs of our customers during the pandemic. We have assembled a Critical Care Drug Task Force, made up of our procurement specialists, clinical health systems pharmacists, and supply chain professionals, that is focused on securing additional product where available, sourcing back-up products, and protecting our operations across all locations and facilities. We are also working with manufacturers through several channels, including our ClarusONE Sourcing Services LLP (“ClarusONE”) and global sourcing teams in London, and our leaders are actively engaged in addressing potential shortages. We have engaged with industry partners and government agencies to gain visibility into supply and demand. Additionally, we have a robust Business Continuity and Disaster Recovery Program (“BCRP”) and we have proactively enhanced our BCRP in response to the COVID-19 pandemic to protect the supply chain to minimize disruption in healthcare, protect our customers, ensure the safety and security of our employees and workplaces, and ensure the continuity of critical business processes.
The situation remains fluid and we are taking a proactive approach to protect inventory during this crisis and ensure our provider partners have needed supplies and medications to help prevent the spread of the disease and treat those that are ill. COVID-19 has put an unprecedented strain on the supply of high-demand PPE, including N95 masks, gloves, as well as disinfecting sprays and wipes. The supply chain has improved over the initial impact of pandemic-related demand, and we continue to closely monitor demand by customer type and certain PPE and infection prevention items are still in short supply. Our allocation approach has helped us avoid stock outs in many critical product categories, allowing us to provide PPE supplies to many more customers for a much longer time. We anticipate these market conditions will remain for the foreseeable future. Our efforts to help the supply chain have included sourcing products from new suppliers all over the world, working closely with the federal government to help with the nation’s response and collaborating with partners to source, develop, and deliver new products to market.
Risks and Forward-Looking Information
The COVID-19 pandemic has disrupted the global economy and exacerbated uncertainties inherent in estimates, judgments, and assumptions used in our forecasts. We face numerous uncertainties in estimating the direct and indirect effects of COVID-19 on our future business operations, financial condition, results of operations, and liquidity. The full extent to which COVID-19 will impact us depends on many factors and future developments, including: the duration and spread of the virus; governmental actions to limit the spread of the virus; potential seasonality of viral outbreaks; potential new strains or variants of the original virus; the amount of COVID-19 vaccines authorized, manufactured, distributed, and administered; the amount of ancillary supply kits assembled and distributed; the effectiveness of COVID-19 vaccines and governmental measures in controlling the spread of the virus; and the effectiveness of treatments of infected individuals. Due to several rapidly changing variables related to the COVID-19 pandemic, estimations of future economic trends and the timing of when stability will return remains challenging. Additionally, we periodically review our intangible and other long-lived assets for impairment when events or changes in circumstances indicate the carrying value may not be recoverable. Key assumptions and estimates about future values in our impairment assessments can be affected by a variety of factors, including the impacts of the global pandemic on industry and economic trends as well as on our business strategy and internal forecasts. Material changes to key assumptions and estimates can decrease the projected cash flows or increase the discount rates and have resulted in impairment charges of certain long-lived assets as disclosed in Financial Note 4, “Restructuring, Impairment, and Related Charges,” to the accompanying consolidated financial statements included in this Annual Report on Form 10-K, and could potentially result in future impairment charges. Refer to Item 1A - Risk Factors in Part I of this Annual Report on Form 10-K for a disclosure of risk factors related to COVID-19.

Opioid-Related Litigation and Claims
We are a defendant in approximately 3,200 legal proceedings asserting claims related to the distribution of controlled substances (opioids) in federal and state courts throughout the U.S., and in Puerto Rico and Canada. Those proceedings include approximately 2,900 federal cases and approximately 300 state court cases throughout the U.S., and cases in Puerto Rico and Canada. We continue to be involved in discussions with the objective of achieving broad resolution of opioid-related claims of states, their political subdivisions and other government entities (“governmental entities”). We are in ongoing, advanced discussions with state attorneys general and plaintiffs’ representatives regarding a framework under which, in order to resolve the claims of governmental entities, the three largest U.S. pharmaceutical distributors would pay up to approximately $21.0 billion over a period of 18 years, with up to approximately $8.0 billion to be paid by us, of which more than 90% is anticipated to be used to remediate the opioids crisis. Most of the remaining amount relates to plaintiffs’ attorneys fees and costs, and would be payable over a shorter time period. In addition, the proposed framework would require the three distributors, including the Company, to adopt changes to anti-diversion programs.
We have concluded that discussions under that framework have reached a stage at which a broad settlement of opioid claims by governmental entities is probable, and the loss related thereto can be reasonably estimated as of March 31, 2021. As a result of that conclusion, and our assessment of certain other opioid-related claims, we recorded a charge of $8.1 billion for the year ended March 31, 2021 within “Claims and litigation charges, net” in our Consolidated Statement of Operations, related to our share of the settlement framework described above, as well as other opioid-related claims. Because of the many uncertainties associated with any potential settlement arrangement or other resolution of opioid-related litigation, including the uncertainty of the scope of participation by plaintiffs in any potential settlement, we are not able to reasonably estimate the upper or lower ends of the range of ultimate possible loss for all opioid-related litigation matters. In light of the uncertainty of the timing of amounts that would be paid with respect to the charge, the charge was recorded in “Long-term litigation liabilities” in our Consolidated Balance Sheet as of March 31, 2021. Moreover, in light of this uncertainty, the amount of any ultimate loss may differ materially from the amount accrued.
While we continue to be involved in discussions regarding a potential broad settlement framework, we also continue to prepare for trial in these pending matters. We believe that we have valid defenses to the claims pending against us and, absent an acceptable settlement, intend to vigorously defend against all such claims. An adverse judgment or negotiated resolution in any of these matters could have a material adverse impact on our financial position, cash flows or liquidity, or results of operations. Refer to Financial Note 19, “Commitments and Contingent Liabilities,” to the accompanying consolidated financial statements included in this Annual Report on Form 10‑K for more information.
State Opioid Statutes
Legislative, regulatory, or industry measures to address the misuse of prescription opioid medications could affect our business in ways that we may not be able to predict. In April 2018, the State of New York adopted the Opioid Stewardship Act (“OSA”) which required the imposition of an annual surcharge on all manufacturers and distributors licensed to sell or distribute opioids in New York. On December 19, 2018, the U.S. District Court for the Southern District of New York found the law unconstitutional and issued an injunction preventing the State of New York from enforcing the law. The State of New York appealed to the U.S. Court of Appeals for the Second Circuit. The State of New York has subsequently adopted an excise tax on sales of opioids in the State, which became effective July 1, 2019. The law adopting the excise tax made clear that the OSA would apply only to opioid sales on or before December 31, 2018. The excise tax applies only to the first sale occurring in New York, and thus may not apply to sales from our distribution centers in New York to New York customers.
On September 14, 2020, a panel of the U.S. Court of Appeals for the Second Circuit reversed the district court’s decision on procedural grounds. The Healthcare Distribution Alliance filed a petition for panel rehearing, or, in the alternative, for rehearing en banc with the U.S. Court of Appeals for the Second Circuit; that petition was denied on December 18, 2020. On February 12, 2021, the U.S. Court of Appeals for the Second Circuit granted a motion by the Healthcare Distribution Alliance to stay its mandate pending the filing and disposition of a petition for writ of certiorari before the U.S. Supreme Court. The due date for filing such a petition is May 17, 2021. Unless the appellate court’s decision is overturned, the OSA will be reinstated for calendar years 2017 and 2018 (but not beyond those years), and, subject to any further legal challenge, we will have to pay our ratable share of the annual surcharge for those two years. During the second quarter of 2021, we reflected an estimated liability of $50 million for the OSA surcharge in our accompanying consolidated financial statements on the assumption that the appellate court’s decision will stand. Refer to Note 19, “Commitments and Contingent Liabilities,” to the accompanying consolidated financial statements included in this Annual Report on Form 10‑K for more information.

Revenues
Revenues increased for 2018the years ended March 31, 2021 and 2017 increased 5% and 4%2020 compared to the same periods a year agorespective prior years primarily due to market growth, reflecting growing drug utilization and price increases, our business acquisitions andincluding expanded business with existing customers, within our North America pharmaceutical distribution businesses. TheseU.S. Pharmaceutical segment. Market growth includes growing drug utilization, price increases, for 2018 and 2017 werenewly launched products, partially offset by price deflation associated with brandbranded to generic drug conversion and loss of customers andconversion.
Gross Profit
Gross profit increased for 2018 alsothe year ended March 31, 2021 compared to the prior year primarily in our Medical-Surgical Solutions segment driven by the demand for COVID-19 tests and the contribution from kitting and distribution of ancillary supplies for COVID-19 vaccines, partially offset by the unfavorable impact from PPE and other related products largely due to inventory charges. Gross profit was favorably impacted by growth of specialty pharmaceuticals and the contribution from our vaccine distribution programs in our U.S. Pharmaceutical segment. Gross profit was unfavorably impacted by the adverse impacts from COVID-19 largely during the first quarter of 2021, including disruptions of doctors’ office operations, deferred or cancelled elective procedures, lower demand for pharmaceuticals, and overall reduction of foot traffic in pharmacies.
Gross profit increased for the year ended March 31, 2020 compared to the prior year primarily due to market growth in our Medical-Surgical Solutions segment, partially offset by unfavorable effects of foreign currency exchange fluctuations. Gross profit and gross profit margin for the year ended March 31, 2020 compared to the prior year were unfavorably impacted by lower gains from antitrust legal settlements, partially offset by higher last-in, first-out (“LIFO”) credits in 2020. The impact from COVID-19 increased gross profit by less than 1% and decreased gross profit margin by less than 10 basis points for the year ended March 31, 2020.
Gross profit for the years ended March 31, 2021, 2020, and 2019 included LIFO inventory credits of $38 million, $252 million, and $210 million, respectively. The lower LIFO credits in 2021 compared to 2020 is primarily due to higher brand inflation and delays of branded off-patent to generic drug launches. The higher LIFO credits in 2020 compared to 2019 is primarily driven by higher generic deflation. Refer to the “Critical Accounting Policies and Estimates” section included in this Financial Review for further information. Gross profit for the years ended March 31, 2021, 2020, and 2019 also included net cash proceeds received of $181 million, $22 million, and $202 million, respectively, representing our share of antitrust legal settlements.
Total Operating Expenses
A summary and description of the majoritycomponents of our McKesson Technology Solutions businessestotal operating expenses for the years ended March 31, 2021, 2020, and 2019 is as follows:

Selling, distribution, general, and administrative expenses (“Core MTS Business”SDG&A”): SDG&A consists of personnel costs, transportation costs, depreciation and amortization, lease costs, professional fee expenses, and administrative expenses.
Claims and litigation charges, net: These charges include adjustments for estimated probable settlements related to our controlled substance monitoring and reporting, and opioid-related claims, as well as any applicable income items or credit adjustments due to subsequent changes in estimates. Legal fees to defend claims, which are expensed as incurred, are included within SDG&A. We have reclassified prior period amounts to conform to the current period presentation.
Goodwill impairments charges: We perform an impairment test on goodwill balances annually in the third quarter and more frequently if indicators for potential impairment exist. The resulting goodwill impairment charges are reflected within this line item.
Restructuring, impairment, and related charges: Restructuring charges that are incurred for programs in which we change our operations, the scope of a joint venturebusiness undertaken by our business units, or the manner in March 2017,which that business is conducted as further discussed below.well as long-lived asset impairments.

Total operating expenses for the years ended March 31, 2021, 2020, and 2019 were affected by the following significant items:
2021
SDG&A includes opioid-related costs of $153 million, primarily related to litigation expenses;
SDG&A reflects cost savings of $95 million on travel and entertainment due to travel and meeting restrictions associated with COVID-19;
SDG&A reflects charges of $58 million to remeasure assets and liabilities held for sale to fair value less costs to sell related to the completed contribution of the Core MTS Business, significant government reimbursement reductions in the United Kingdom (“U.K.”), the competitive sell-side environment and weakermajority of our German pharmaceutical manufacturer pricing trends. These decreases in 2018 were partially offset by market growth, procurement benefits realized through the joint sourcing entity, ClarusONE Sourcing Services LLP (“ClarusONE”), higher last-in, first-out (“LIFO”) credits and ourwholesale business acquisitions.
Gross profit and gross profit margin decreased in 2017 primarily due to weaker pharmaceutical manufacturer pricing trends, the competitive sell-side pricing environment, our mix of business and lower compensation fromcreate a branded pharmaceutical manufacturer from our U.S. Pharmaceutical distribution business. These decreases for 2017 were partially offset by our business acquisitions, LIFO inventory credits, higher cash receipts from antitrust legal settlements and higher procurement benefits. Gross profit for 2017 and 2016 benefited from $144 million and $76 million of cash receipts representing our share of antitrust legal settlements. LIFO credits were $99 million and $7 million in 2018 and 2017 and LIFO charges were $244 million in 2016. LIFO credits were higher in 2018 compared to 2017 due to higher net effect of price declines, partially offset by the lower inventory level. LIFO expense was recognized in 2016 primarily due to net effects of price increases.
Our Distribution Solutions segment experienced weaker pharmaceutical manufacturer pricing trends over the last three years.
On March 1, 2017, we contributed our Core MTS Business to the newly formed joint venture Change Healthcare, LLC (“Change Healthcare”) under the terms ofwith WBA in which we have a contribution agreement entered into between McKesson and Change Healthcare Holdings, Inc. (“Change”) and others including shareholders of Change. We retained30% ownership interest within our RelayHealth Pharmacy (“RHP”) and Enterprise Information Solutions (“EIS”) businesses. The RHP business was transferred to our MDS segment, effective April 1, 2017, and the EIS business was sold to a third party in the third quarter of 2018. We accounted for this transaction as a sale of the Core MTS Business and a subsequent purchase of a 70% interest in the newly formed joint venture.International segment.

Goodwill impairment charges of $1.8 billion in our European Retail Pharmacy (“European RP”) and European Pharmaceutical Distribution (“European PD”) reporting units within the International segment. Of these impairment charges, $238 million was recognized upon the 2019 first quarter segment changes, which resulted in two new reporting units. The remaining charges primarily were due to declines in the pre-tax gain recognized in 2017 fromreporting units’ estimated future cash flows and the contributionselection of the Core MTS Business. Income from continuing operations before income taxes decreased in 2018 also due to the goodwillhigher discount rates. These impairment charges generally were not deductible for income tax purposes. The declines in estimated future cash flows primarily were attributed to additional government reimbursement reductions and competitive pressures within the U.K. The risk of successfully achieving certain business initiatives was the primary factor in the use of a higher discount rate. At March 31, 2019, both the European RP and European PD reporting units had no remaining goodwill balances; and
Restructuring, impairment, and related charges, net primarily includes employee severance and exit-related costs of $352 million for our Distribution Solutions segment, the2019 restructuring initiatives, as further discussed below and long-lived asset impairment charges of $245 million primarily for our proportionate share of loss fromU.K. business (mainly pharmacy licenses) within our equity method investment in Change HealthcareInternational segment driven by additional government reimbursement reductions and loss on debt extinguishment.
Our reported income tax benefit rate was 22.2% in 2018 and income tax expense rates were 23.4% and 27.9% in 2017 and 2016. Fluctuations in our reported income tax rates are primarily due to change in tax laws, including the recently enacted 2017 Tax Act, the impact of nondeductible impairment charges and varying proportions of income attributable to foreign countries that have income tax rates different from the U.S. rate.
During 2018, as a result of the 2017 Tax Act, we have recognized a provisional tax benefit of $1,324 million due to the re-measurement of certain deferred taxes to the lower U.S. federal tax rate and a provisional tax expense of $457 million for the one-time tax imposed on certain accumulated earnings and profits (“E&P”) of our foreign subsidiaries. Refer to Financial Note 10, “Income Taxes,” to the accompanying consolidated financial statements appearing in this Annual Report on Form 10‑K for additional information.

Net income attributable to McKesson Corporation was $67 million, $5,070 million and $2,258 million in 2018, 2017 and 2016 and diluted earnings per common share attributable to McKesson Corporation from continuing operations were $0.30, $23.28 and $9.84.

Foundation
During the fourth quarter of 2018, the Foundation was established to provide opioid education to patients, caregivers, and providers, address policy issues, and increase patient access to life-saving treatments. In March 2018, we made a pledge to the Foundation and incurred a pre-tax charitable contribution expense of $100 million ($64 million after-tax) for 2018, which was recorded in operating expenses within Corporate Expenses.

FINANCIAL REVIEW (Continued)


During the second quarter of 2018, our McKesson Europe reporting unit had a decline in its estimated future cash flows, primarily in our United Kingdom (“U.K.”) retail business, driven by significant government reimbursement reductions affecting retail pharmacy economics across the U.K. market. As a result, we performed the interim impairment testoperating structure was realigned commencing in the second quarter of 20182021 into four reportable segments: U.S. Pharmaceutical, International, Medical-Surgical Solutions, and RxTS. These reportable segments encompass all operating segments of the Company. The second quarter segment realignment resulted in changes in multiple reporting units across the Company. As a result, we were required to perform a goodwill impairment test for these reporting units and recorded a non-cash goodwill impairment charge in our European RP reporting unit of $350$69 million (pre-tax and after-tax).  Duringduring the fourthsecond quarter of 2018, this reporting unit had a further decline in its estimated future cash flows driven by weakening script growth projections in our U.K. business and by a more competitive environment in France. Based on the annual goodwill impairment test, we recorded non-cash charges of $933 million (pre-tax and after-tax) in the fourth quarter of 2018 to impair this reporting unit’s goodwill balance. The discount rates and terminal growth rates were 7.5% and 1.25% for the 2018 second quarter interim test and 8.0% and 1.25% for the 2018 annual test, compared to 7.0% and 1.5% in our 2017 annual impairment test.2021. At March 31, 2018, this reporting unit had a remaining goodwill2021, the balance of $1,851 million.
Rexall Health: As a resultgoodwill for our reporting units in Europe was approximately nil and the remaining balance of the 2018 annual impairment test, we recognized a non-cash goodwill impairment charge (pre-tax and after-tax) of $455 million in 2018. During the fourth quarter of 2018, this reporting unit had a decline in its estimated future cash flows primarily driven by significant generics reimbursement reductions across Canada and minimum wage increases in multiple provinces which can only be partially mitigated through the business’ cost saving efforts. The discount rate and terminal growth rate used in the International segment primarily relates to one of our reporting units in Canada.
We evaluate goodwill for impairment on an annual basis as of October 1, and at an interim date, if indicators of potential impairment exist. The annual impairment testing were 10.0% and 2.0%. At March 31, 2018,performed in 2021 did not indicate any impairment of goodwill. As of the Rexall Health reporting unit had no remaining goodwill related to our acquisition of Rexall Health.

Othertesting date, other risks, expenses, and future developments, that we were unablesuch as additional government actions, increased regulatory uncertainty, and material changes in key market assumptions limit our ability to anticipate as of the testing dates in 2018 may require us to further revise the estimated futureestimate projected cash flows, which could adversely affect the fair value of ourvarious reporting units in future periods. Asperiods, including our McKesson Canada reporting unit within our International segment and our RxCrossroads reporting unit within our RxTS segment, where the risk of a result,material goodwill impairment is higher than other reporting units.

FINANCIAL REVIEW (Continued)

On October 1, 2019, we voluntarily changed our annual goodwill impairment testing date from January 1 to October 1 to better align with the timing of our annual long-term planning process. This change was not material to our consolidated financial statements as it did not delay, accelerate, or avoid any potential goodwill impairment charge. Refer to Note 12, “Goodwill and Intangible Assets, Net,” to the accompanying consolidated financial statements included in this Annual Report on Form 10-K for further information.
Restructuring Initiatives and Long-Lived Asset Impairments
During the first quarter of 2022, we approved an initiative to increase operational efficiencies and flexibility by transitioning to a partial remote work model for certain employees. This initiative primarily led us to rationalize our office space in North America. Where we determine to cease using office space, we plan to exit the portion of the facility no longer used. We also may retain and repurpose certain other office locations. We expect to incur total charges of approximately $180 million to $280 million for this initiative, consisting primarily of exit related costs, accelerated depreciation and amortization of long-lived assets, and asset impairments. This initiative is expected to be requiredcompleted in 2022.
During the first quarter of 2021, we committed to an initiative within the U.K., which is included in our International segment, to further drive transformational changes in technologies and business processes, operational efficiencies, and cost savings. The initiative includes reducing the number of retail pharmacy stores, decommissioning obsolete technologies and processes, reorganizing and consolidating certain business operations, and related headcount reductions. We expect to incur total charges of approximately $85 million to $90 million, of which $57 million of charges were recorded to date. The initiative is expected to be substantially complete in 2022 and estimated remaining charges primarily consist of accelerated amortization of long-lived assets, facility and other exit costs, and employee-related costs.
In the fourth quarter of 2019, we committed to certain programs to continue our operating model and cost optimization efforts. We continue to implement centralization of certain functions and outsourcing through an expanded arrangement with a third-party vendor to achieve operational efficiency. The programs also include reorganization and consolidation of business operations, related headcount reductions, the further closures of retail pharmacy stores in Europe, and closures of other facilities. Total charges of $297 million were recorded to date. This initiative was substantially complete in 2021 and remaining costs we expect to record additionalunder this initiative are not material.
We also committed to certain actions in connection with the previously announced relocation of our corporate headquarters from San Francisco, California to Irving, Texas, which became effective April 1, 2019. Total charges of $105 million were recorded to date. The relocation was substantially complete in January 2021 and remaining costs we expect to record under this initiative, primarily relating to lease costs, are not material.
In the second quarter of 2018, we committed to a restructuring plan, which primarily consisted of the closures of underperforming retail pharmacy stores in the U.K., and a reduction in workforce. The plan was substantially complete in 2020.
On April 25, 2018, we announced a strategic growth initiative intended to drive long-term incremental profit growth and to increase operational efficiency. The initiative consisted of multiple growth priorities and plans to optimize our operating models and cost structures primarily through centralization, cost management, and outsourcing of certain administrative functions. As part of the growth initiative, we committed to implement certain actions including a reduction in workforce, facility consolidation, and store closures. This set of initiatives was substantially complete by the end of 2020.
Restructuring, impairment, charges. and related charges for the years ended March 31, 2021, 2020, and 2019 also includes long-lived asset impairment charges of $115 million, $112 million, and $245 million, respectively, primarily related to our retail pharmacy businesses in Canada and Europe within our International segment. In addition, certain charges related to restructuring initiatives are included under the caption “Cost of sales” in our Consolidated Statements of Operations and were not material for the years ended March 31, 2021, 2020, and 2019.
Refer to Financial Note 3, “Goodwill4, “Restructuring, Impairment, and Related Charges,” to the accompanying consolidated financial statements appearing in this Annual Report on Form 10-K for additional information.

Restructuring and Asset Impairments

McKesson Europe: Due to the previously described decline in future estimated cash flows related to our U.K. retail business, we also recorded total non-cash pre-tax charges of $189 million ($157 million after-tax) to impair the carrying value of certain intangible assets (primarily pharmacy licenses) and store assets during the second quarter of 2018. Additionally, during the fourth quarter of 2018, due to further declines in estimated future cash flows in our European business, we also recorded a non-cash pre-tax charge of $257 million ($253 million after-tax) to impair the carrying value of certain intangible assets (primarily customer relationships) and capitalized software assets.

On September 29, 2017, we committed to a restructuring plan, which primarily consists of the closures or sales of underperforming retail stores in the U.K. and a reduction in workforce. The plan is expected to be substantially implemented prior to the first half of 2019. As part of this plan, we recorded pre-tax restructuring charges of $74 million ($67 million after-tax) in operating expenses during 2018 primarily representing employee severance and lease exit costs.

Distribution Solutions
North America pharmaceutical distribution and services revenues increased over the last two years primarily due to market growth, reflecting growing drug utilization, price increases, higher revenues associated with our acquisitions and expanded business with existing customers. These increases were partially offset by price deflation associated with brand to generic drug conversion and loss of customers.
International pharmaceutical distribution and services revenues increased 10% and 6% in 2018 and 2017. Excluding foreign currency effects, revenues increased 5% in 2018 and 11% in 2017 primarily due to our business acquisitions and market growth.
Medical-Surgical distribution and services revenues increased over the last two years primarily due to market growth.
Technology Solutions
Technology Solutions revenues for 2018 and 2017 decreased primarily due to the 2017 fourth quarter contribution of the Core MTS Business to form the Change Healthcare joint venture, the April 2017 transition of our RHP business to our Distribution Solutions segment and the 2018 third quarter sale of our EIS business. As a result, this segment’s 2018 revenues included only our EIS business.

Gross profit for 2017 and 2016 also includes $144 million and $76 million ofOther income, net cash proceeds representing our share of antitrust legal settlements.

Gross profit and gross profit margin decreased in 2018 and 2017 compared to the same periods a year ago. The decreases in 2018 were primarily due the previously described contribution of our Core MTS Business to Change Healthcare.
Distribution Solutions
Distribution Solutions segment’s gross profit increased 12% in 2018 and decreased 1% in 2017. As a percentage of revenues, gross profit increased by 29 bp in 2018 and decreased by 26 bp in 2017.
Gross profit and gross profit margin for 2018 increased compared to the same period a year ago primarily due to market growth, procurement benefits realized through ClarusONE, higher LIFO inventory credits, our business acquisitions and the transfer of our RHP business from our Technology Solutions segment. These increases were partially offset by significant government reimbursement reductions in the U.K., the competitive sell-side pricing environment, weaker pharmaceutical manufacturer pricing trends and our mix of business. Gross profit and gross profit margin for 2017 decreased primarily due to weaker pharmaceutical manufacturer pricing trends, the competitive sell-side pricing environment and lower compensation from a branded pharmaceutical manufacturer in our U.S. Pharmaceutical distribution business, partially offset by LIFO inventory credits, higher cash receipts representing our share of antitrust legal settlements, higher procurement benefits and our business acquisitions. Gross profit also reflects the impact of recent customer consolidation activities.
Our Distribution Solutions segment experienced weaker pharmaceutical manufacturer pricing trends over the last three years.
Our LIFO inventory credits were $99 million and $7 million in 2018 and 2017 and LIFO charges were $244 million in 2016. Our North America distribution business uses the LIFO method of accounting for the majority of its inventories, which results in cost of sales that more closely reflects replacement cost than under other accounting methods. The business’ practice is to pass on to customers published price changes from suppliers. Manufacturers generally provide us with price protection, which limits price-related inventory losses. A LIFO charge is recognized when the net effect of price increases on pharmaceutical and non-pharmaceutical products held in inventory exceeds the net impact of price declines, including the effect of branded pharmaceutical products that have lost market exclusivity. A LIFO credit is recognized when the net effect of price declines exceeds the net impact of price increases on pharmaceutical and non-pharmaceutical products held in inventory. Our annual LIFO charge or credit is affected by changes in year-end inventory quantities, product mix and manufacturer pricing practices, which may be influenced by market and other external factors. Changes to any of the above factors could have a material impact to our annual LIFO credit or expense. LIFO credits were higher in 2018 compared to 2017 due to higher net effect of price declines, partially offset by lower inventory level. LIFO expense was recognized in 2016 primarily due to net effects of price increases. As ofyear ended March 31, 2018 and 2017, pharmaceutical inventories at LIFO did not exceed current replacement cost.

Technology Solutions
Technology Solutions segment’s gross profit decreased in 2018 and 2017. Gross profit and gross profit margin for 2018 decreased primarily due to the 2017 fourth quarter contribution of the Core MTS Business, the transfer of our RHP business to our Distribution Solutions segment and the 2018 third quarter sale of our EIS business. As a result, this segment’s 2018 gross profit and gross profit margin included only our EIS business.
Gross profit for 2017 decreased due to one less month of gross profit from the Core MTS Business, which was contributed to the joint venture on March 1, 2017. Gross profit margin for 20172021 increased primarily due to a decline in hospital software revenues, lower severance charges, ongoing cost management efforts and the prior year sales of businesses, partially offset by a lower margin from our hospital software business. Gross profit margin for 2017 also benefited from lower depreciation and amortization expenses related to the Core MTS Business’ assets, which were classified as held for sale since the second quarter of 2017. Depreciation and amortization related to the long-lived assets ceased as of the date they were determined as held for sale.

FINANCIAL REVIEW (Continued)


Total operating expenses increased in 2018 compared to 2017 primarily due to:
Non-cash goodwill impairment charges (pre-tax and after-tax) of $1,283 million for our McKesson Europe reporting unit and $455 million for our Rexall Health reporting unit;
Non-cash pre-tax long-lived asset impairment charges of $446 million ($410 million after-tax) and pre-tax restructuring charges of $74 million ($67 million after-tax) for our McKesson Europe business;
Non-cash charges of $33 million (pre-tax and after-tax) to impair the carrying value of certain intangible assets (primarily customer relationships) for our Rexall Health business. The impairment was primarily due to the decline in the estimated future cash flows from certain pharmacies of Rexall Health’s business, driven primarily by generics reimbursement reductions implemented across Canada; and
Higher expenses due to our business acquisitions.
We expect to record total pre-tax restructuring charges of approximately $90 million to $130 million for our McKesson Europe business, of which $74 million of pre-tax charges were recorded through the end of 2018.  Estimated remaining restructuring charges primarily consist of lease termination and other exit costs.
Total operating expenses increased in 2017 compared to 2016 primarily due to our acquisitions and higher acquisition-related expenses and intangible amortization, partially offset by lower restructuring charges and cost savings associated with the 2016 Cost Alignment Plan, ongoing expense management efforts and lower bad debt expense. Total operating expenses for 2016 include a pre-tax gain from the 2016 sale of a business.
Technology Solutions
Technology Solutions segment had operating credits of $104 million and $2,799 million in 2018 and 2017 primarily due to gains that offset operating expenses.

Total operating expenses for 2018 benefited from a pre-tax gain of $109 million (after-tax gain of $30 million) from the 2018 third quarter sale of our EIS business, a pre-tax credit of $46 million ($30 million after-tax) from the re-measurement of the liability related to a tax receivable agreement with Change Healthcare shareholders and a pre-tax gain of $37 million (after-tax gain of $22 million) representing the final net working capital and other adjustments from the 2017 Healthcare Technology Net Asset Exchange.

On August 1, 2017, we entered into an agreement with a third party to sell our EIS business for $185 million, subject to adjustments for net debt and working capital. On October 2, 2017, the transaction closed upon satisfaction of all closing conditions including the termination of the waiting period under U.S. antitrust laws. We received net cash proceeds of $169 million after $16 million of assumed net debt by the third party. We recognized a pre-tax gain of $109 million (after-tax gain of $30 million) upon the disposition of this business in the third quarter of 2018 within operating expenses in our Technology Solutions segment.

Total operating expenses for 2017 benefited from the pre-tax gain of $3,947 million (after-tax gain of $3,018 million) from the contribution of Core MTS Business, partially offset by a non-cash pre-tax goodwill impairment charge of $290 million ($282 million after-tax) for the EIS reporting unit, cost savings from the 2016 Cost Alignment Plan and ongoing cost management efforts and one less month of expenses from the Core MTS Business. Total operating expenses for 2016 include a pre-tax gain from the 2016 sale of a business.
Corporate
Corporate expenses increased 43% in 2018 compared to the prior year primarily due to a charitable contribution expensenet gains recognized from our equity investments of $100 million ($64 million after-tax)$133 million. This primarily reflects mark-to-market gains on our investments in certain U.S. growth stage companies in the healthcare industry and realized gains on the exit of some of these investments as further described in Financial Note 17, “Fair Value Measurements,” to the Foundationaccompanying consolidated financial statements included in this Annual Report on Form 10-K. In future periods, fair value adjustments recognized in our operating results for these types of investments may be adversely impacted by market volatility. Other income, net also increased year over year due to pension settlement charges of $122 million recognized in 2020 related to our previously approved termination of the frozen U.S. defined benefit pension plan. In connection with the pension plan termination, we purchased annuity contracts from an insurer that will pay and higher professional fees incurredadminister the future pension benefits of the remaining participants.
Other income, net, for Corporate initiatives.
Corporate expensesthe year ended March 31, 2020 decreased 17% in 2017 compared to the prior year primarily due to lower restructuringthe 2020 pension settlement charges described above and cost savings associated with the 2016 Cost Alignment Plan, including lower compensation and benefit costs and outside service fees. Corporate expenses for 2017 also benefited from a pre-tax gain of $15 million from the sale-leaseback transaction of our corporate headquarters building.

LossEquity Earnings and Charges from Equity Method Investment in Change Healthcare: 2018 includedHealthcare Joint Venture
Until the separation of our investment in Change Healthcare JV on March 10, 2020, we accounted for this investment using the equity method of accounting. Excluding the impairment and transaction-related items described below, our proportionate share of loss from our investment in Change Healthcare of $248JV for the years ended March 31, 2020 and 2019 was $119 million and $194 million, respectively, which primarily consisted ofincludes transaction and integration expenses incurred by the joint venture and basis differences between the joint venture and McKesson including amortization of fair value adjustments including amortization expenses associated withadjustments. During the first quarter of 2020 and for the year ended March 31, 2019, we owned approximately 70% of this joint venture.
On June 27, 2019, common stock and certain other securities of Change began trading on the NASDAQ (“IPO”). On July 1, 2019, upon the completion of its IPO, Change contributed net cash proceeds it received from its offering of common stock to Change Healthcare JV in exchange for additional membership interests of Change Healthcare JV at the equivalent of its offering price of $13 per share. The proceeds from the concurrent offering of other securities were also used by Change to acquire certain securities of Change Healthcare JV. As a result, McKesson’s equity method intangible assets, partially offset by a tax benefit of $76 million primarily dueinterest in Change Healthcare JV was reduced from 70% to a reductionapproximately 58.5%, which was used to recognize our proportionate share in net loss from Change Healthcare JV, commencing in the future applicable tax rate relatedsecond quarter of 2020. As a result of the ownership dilution to the 2017 Tax Act.
Acquisition-Related Expenses and Adjustments
Acquisition-related expenses, which included transaction and integration expenses directly related to business acquisitions and the gain on the Healthcare Technology Net Asset Exchange were $168 million, $(3,797) million and $11458.5% from 70%, we recognized a dilution loss of approximately $246 million in 2018, 2017 and 2016. 2018 includes $37 million gain associated with the final net working capital and other adjustments from the Healthcare Technology Net Asset Exchange andsecond quarter of 2020. Additionally, our proportionate share of transactionincome or loss from this investment was subsequently reduced as immaterial settlements of stock option exercises occurred after the IPO and integration expenses incurred byfurther diluted our ownership.
In the second quarter of 2020, we recorded an other-than-temporary-impairment (“OTTI”) charge of $1.2 billion to our investment in Change Healthcare. 2017 includes a pre-tax gainHealthcare JV, representing the difference between the carrying value of $3,947 millionour investment and the fair value derived from the corresponding closing price of Change’s common stock at September 30, 2019. This charge was included within “Equity earnings and charges from investment in Change Healthcare Technology Net Asset Exchange. ExpensesJoint Venture” in 2018 were higher primarily due to our proportionate shareConsolidated Statements of transaction and integration expenses incurred byOperations for the year ended March 31, 2020.
On March 10, 2020, we completed the previously announced separation of our interest in Change Healthcare. ExpensesHealthcare JV, which eliminated our investment in 2017 were higher primarily due to our business acquisitionsthe joint venture. The separation was effected through the split-off of UDG, Vantage, Biologics and Rexall Health, partially offset by a decline in expenses associated with our February 2014 acquisition of McKesson Europe and February 2013 acquisition of PSS World Medical,PF2 SpinCo, Inc. (“PSSI”SpinCo”), a wholly owned subsidiary of the Company that held all of our interest in Change Healthcare JV, to certain of our stockholders through an exchange offer (“Split-off”), followed by the merger of SpinCo with and into Change, with Change surviving the merger (“Merger”). Our integration of PSSI and McKesson Europe were substantially completed in 2017.

Amortization ExpensesIn connection with the exchange offer, on March 9, 2020, we distributed all 176.0 million outstanding shares of Acquired Intangible Assets
Amortization expensescommon stock of acquired intangible assets directlySpinCo to participating holders of the Company’s common stock in exchange for 15.4 million shares of McKesson common stock. Following consummation of the exchange offer, on March 10, 2020, the Merger was consummated, with each share of SpinCo common stock converted into one share of Change common stock, par value $0.001 per share, with cash being paid in lieu of fractional shares of Change common stock. The Split-off and Merger are intended to be generally tax-free transactions to McKesson and its shareholders for U.S. federal income tax purposes. Following the Split-off, we do not beneficially own any of Change’s outstanding securities. In connection with this transaction, we recognized a net gain for financial reporting purposes of $414 million during the fourth quarter of 2020, which was largely driven by the reversal of a related to business acquisitionsdeferred tax liability. Under the agreement with Change Healthcare JV, McKesson, Change, and the formationcertain subsidiaries of the Change Healthcare joint venture were $792 million, $440 millionJV, there may be changes in future periods to the amount reversed. Any such change is not expected to be material.
After the separation, Change Healthcare JV is required under the TRA to pay McKesson 85% of the net cash tax savings realized, or deemed to be realized, resulting from depreciation or amortization allocated to Change by McKesson. The receipt of any payments under the TRA is dependent upon Change benefiting from this depreciation or amortization in future tax return filings, which creates uncertainty over the amount, timing and $423 millionprobability of the gain recognized. As such, we accounted for the TRA as a gain contingency, with no receivable recognized as of March 31, 2021 nor 2020.
Interest Expense
Interest expense decreased in 2018, 2017 and 2016. These expenses were primarily recorded in our operating expenses and in our proportionate share of loss from2021 compared to the equity method investment in Change Healthcare.

Segment Operating Profit (Loss)
Distribution Solutions: Operating profit and operating profit margin decreased for 20182020 compared to the same period aprior year ago primarily due to higher operating expenses as a percentage of revenues driven primarily by a goodwill impairment charges and restructuring and long-lived asset impairment charges related to our McKesson Europe and Rexall Health businesses. These decreases were partially offset by the improved gross profit margin primarily due to market growth within our North America distribution businesses, procurement benefits, our business acquisitions and higher LIFO credits. 2018 operating profit and operating profit margin were also unfavorably affected by government reimbursement reductions in the U.K. and the competitive sell-side pricing environment.
Operating profit margin decreased for 2017 primarily due to a declinedecrease in gross profit margin reflecting weaker pharmaceutical manufacturer pricing trends, the competitive sell-side pricing environment and lower compensation from a branded pharmaceutical manufacturer from our U.S. Pharmaceutical distribution business. Operating profit and operating profit margin in 2017 benefited from LIFO credits, our acquisitions, lower restructuring charges and cost savings associated with the 2016 Cost Alignment Plan and higher cash receipts representing our shareissuance of antitrust legal settlements.

Income TaxesTax (Benefit) Expense
During 2018, 2017 and 2016, ourWe recorded income tax benefit was $53(benefit) expense of ($695 million), $18 million, and income tax expenses were $1,614$356 million for the years ended March 31, 2021, 2020, and $908 million related to continuing operations.2019, respectively. Our reported income tax benefit rate was 22.2% in 2018 and income tax(benefit) expense rates were 23.4%(13.8%), 1.6%, and 27.9%58.4% in 20172021, 2020, and 2016. Fluctuations in our reported income tax rates are primarily due to change in tax laws, including the recently enacted 2017 Tax Act, the impact of nondeductible impairment charges and varying proportions of income attributable to foreign countries that have income tax rates different from the U.S. rate.2019, respectively.
Our reported income tax benefit rate for 20182021 was favorably impacted by the 2017 Tax Act enacted on December 22, 2017. As a resultcharge for opioid-related claims of the 2017 Tax Act, we recognized a provisional tax benefit of $1,324 million due to the re-measurement of certain deferred taxes to the lower U.S. federal tax rate and a provisional tax expense of $457 million for the one-time tax imposed on certain accumulated E&P of our foreign subsidiaries.$8.1 billion ($6.8 billion after-tax).
Our reported income tax benefitexpense rate for 20182020 was favorably impacted by a net gain on the Change Healthcare JV divestiture of $414 million (pre-tax and after-tax), which was intended to generally be a tax-free split-off for U.S. federal income tax purposes, and unfavorably impacted by charges of $275 million (pre-tax and after-tax) to remeasure assets and liabilities held for sale to fair value less costs to sell related to the completed contribution of the majority of our German pharmaceutical wholesale business to create a joint venture with WBA. Refer to Financial Note 2,“Investment in Change Healthcare Joint Venture” and Note 3,“Held for Sale,” to the accompanying consolidated financial statements included in this Annual Report on Form 10‑K for more information.
Our reported income tax expense rate for 2019 was unfavorably impacted by non-cash pre-tax charges totaling $1,738 millionof $1.8 billion (pre-tax and after-tax) to impair the carrying value of goodwill related toof our McKesson EuropeEuropean RP and Rexall HealthEuropean PD reporting units within our Distribution Solutionsthe International segment, given that no tax benefit was recognized for these charges. Our reported income tax expense rate for 2017 was unfavorably affected by a non-cash pre-tax charge of $290 million to impair the carrying value of goodwill related to our EIS business within our Technology Solutions segment given that the majority of this charge wascharges are generally not deductible for income tax purposes. Refer to Financial Note 3,12, “Goodwill Impairment Charges,and Intangible Assets, Net,” to the accompanying consolidated financial statements appearingincluded in this Annual Report on Form 10‑K for additional information.
On December 19, 2016, we sold various software relating to our Technology Solutions business between wholly owned legal entities within the McKesson group that are based in different tax jurisdictions. The transferor entity recognized a gain on the sale of assets that was not subject to income tax in its local jurisdiction; such gain was eliminated upon consolidation. An entity based in the U.S. was the recipient of the software and is entitled to amortize the fair value of the assets for book and tax purposes. For U.S. GAAP purposes, the tax benefit associated with the amortization of these assets is recognized over the tax lives of the assets. As a result, a net tax benefit of $137 million was recognized prior to the contribution of a portion of these assets to Change Healthcare as described in Financial Note 2, “Healthcare Technology Net Asset Exchange”. In 2018, a net tax benefit of $178 million was recognized associated with the amortization of the software.
In October 2016, amended guidance was issued to require entities to recognize income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs. The amended guidance is effective for us commencing in the first quarter of 2019 on a modified retrospective basis. Upon adoption, the Company anticipates recording approximately $130 million to $160 million of deferred tax assets with a corresponding cumulative-effect increase to retained earnings in the beginning of the period of adoption on its consolidated financial statements for the tax consequences relating to the intra-entity transfer of software.
On March 1, 2017, we contributed assets to Change Healthcare as further described in Financial Note 2, “Healthcare Technology Net Asset Exchange”. While this transaction was predominantly structured as a tax free asset contribution for U.S. federal income tax purposes under Section 721(a) of the Internal Revenue Code, we recorded tax expense of $929 million on the gain. The tax expense was primarily driven by the recognition of a deferred tax liability on the excess book over tax basis in our equity investment in Change Healthcare.
Significant judgments and estimates are required in determining the consolidated income tax provision and evaluating income tax uncertainties. Although our major taxing jurisdictions include the U.S., Canada, and the United Kingdom,U.K., we are subject to income taxes in numerous foreign jurisdictions. Our income tax expense, deferred tax assets and liabilities, and uncertain tax liabilities reflect management’s best assessment of estimated current and future taxes to be paid. We believe that we have made adequate provision for all income tax uncertainties.
We signed the Revenue Agent’s Report from the U.S. Internal Revenue Service (“IRS”) relating to their audit of the fiscal years 2010 through 2012 on December 29, 2017. We file income tax returns in the U.S. federal jurisdiction, various U.S. state and local jurisdictions and various foreign jurisdictions. We are subject to audit by the IRS for fiscal years 2013 through the current fiscal year. We are generally subject to audit by taxing authorities in various U.S. states and in foreign jurisdictions for fiscal years 2010 through the current fiscal year.

U.S. Pharmaceutical
2021 vs. 2020
Operating profit increased for the year ended March 31, 2021 compared to the prior year primarily due to an increase in net cash proceeds received of $159 million in 2021 compared to 2020 representing our share of antitrust legal settlements, growth in specialty pharmaceuticals, and the contribution from our vaccine distribution programs. This was partially offset by a decrease in LIFO credits of $214 million, a charge of $50 million recorded in 2021 related to our estimated liability under the OSA, net impacts from COVID-19, including a less severe cough, cold, and flu season, as well as increased costs for strategic growth initiatives.
2020 vs. 2019
Operating profit increased for the year ended March 31, 2020 compared to the prior year primarily due to market growth in our specialty business. Operating profit and operating profit margin were favorably impacted by a charge of $61 million related to a customer bankruptcy in 2019 and an increase in LIFO credits of $42 million. Operating profit and operating profit margin were unfavorably impacted by customer mix and a decrease in net cash proceeds received of $180 million representing our share of antitrust legal settlements.
International
2021 vs. 2020
Operating loss and operating loss margin improved for the year ended March 31, 2021 compared to the prior year primarily due to a decrease in the charges recorded to remeasure to fair value the assets and liabilities of our German pharmaceutical wholesale business which was contributed to a joint venture with WBA, of which $58 million and $275 million was reflected for the years ended March 31, 2021 and 2020, respectively. This was partially offset by a goodwill impairment charge of $69 million recorded in the second quarter of 2021 related to our European retail pharmacy business. The impacts from COVID-19 in our pharmaceutical distribution and retail pharmacy businesses within Europe also caused unfavorability in our segment results year over year.
2020 vs. 2019
Operating loss and operating loss margin improved for the year ended March 31, 2020 compared to the prior year primarily due to goodwill impairment charges of $1.8 billion in 2019 and a decrease in long-lived asset impairment charges of $112 million in 2020 compared to $245 million in 2019. This was partially offset by the fair value remeasurement charges in 2020 described above and a gain from an escrow settlement of $97 million in 2019 related to our 2017 acquisition of Rexall Health.
Medical-Surgical Solutions
2021 vs. 2020
Operating profit and operating profit margin increased for the year ended March 31, 2021 compared to prior year primarily due to COVID-19, including demand for COVID-19 tests and PPE, as well as the contribution from kitting and distribution of ancillary supplies for COVID-19 vaccines. This was partially offset by inventory charges on certain PPE and other related products, unfavorability in our primary care business due to customer closures largely during the first quarter of 2021, and a less severe cough, cold, and flu season. Additionally, operating profit was favorable year over year due to lower operating expenses, including a decrease in our provision for bad debts.
2020 vs. 2019
Operating profit and operating profit margin increased for the year ended March 31, 2020 compared to prior year primarily due to market growth in our primary care business and lower restructuring charges, partially offset by the remeasurement of assets and liabilities to fair value related to a divestiture that was completed in 2020 and higher operating expenses, including an increase in our provision for bad debts.

Our foreign operations represented approximately 18%15%, 17%, and 17%18% of our consolidated revenues in 2018, 20172021, 2020, and 2016.2019, respectively. Foreign operations are subject to certain risks, including currency fluctuations. We monitor our operations and adopt strategies responsive to changes in the economic and political environment in each of the countries in which we operate. We conduct our business worldwide in local currencies including Euro, British pound sterling, and Canadian dollar. As a result, the comparability of our results reported in U.S. dollars can be affected by changes in foreign currency exchange rates. In discussing our operating results, we may use the term “foreign currency effect”,exchange fluctuations,” which refers to the effect of changes in foreign currency exchange rates used to convert the local currency results of our operations in foreign countries where the functional currency is not the U.S. dollar. We present this information to provide a framework for assessing how our business performed excluding the effect of foreign currency exchange rate fluctuations. In computing the foreign currency effect,exchange fluctuations, we translate our current year results of our operations in foreign countries recorded in local currencies into U.S dollars by applying their respective average foreign currency exchange rates of the corresponding prior year periods, and we subsequently compare those results to the previously reported results of the comparable prior year periods reported in U.S. dollars. Additional information regarding our foreign operations is included in Financial Note 28,22, “Segments of Business,” to the consolidated financial statements appearing in this Annual Report on Form 10-K.

Fiscal 2019 Operating Segments
As previously disclosed in our Quarterly Reports on Form 10-Q for the quarters ended September 30, 2017 and December 31, 2017, the executive who was our segment manager of the Distribution Solutions segment retired from the Company in January 2018. As a result, the Company’s chief operating decision maker (“CODM”) evaluated our management and operating structure. In connection with the completion of this evaluation in the first quarter of 2019, our operating structure is realigned, and we will report our financial results in three reportable segments on a retrospective basis commencing in the first quarter of 2019, as follows:
U.S. Pharmaceutical and Specialty Solutions;
European Pharmaceutical Solutions; and
Medical-Surgical Solutions.
All remaining operating segments and business activities that are not significant enough to require separate reportable segment disclosure will be included in Other. Other primarily consists of McKesson Canada, McKesson Prescription Technology Solutions and our equity method investment in Change Healthcare. The segment changes will reflect how our CODM allocates resources and assesses performance commencing in the first quarter of 2019. The segment changes will not affect the previously issued consolidated financial statements nor earnings per common share of McKesson for historical periods.

Strategic Growth Initiative

On April 25, 2018, the Company announced a multi-year strategic growth initiative, focused on creating innovative new solutions that improve patient care delivery and drive incremental profit growth. The initiative includes a comprehensive review of the Company’s operations and cost structure, designed to increase efficiency, accelerate execution and improve long-term performance. As part of the preliminary phase of this initiative, in April 2018, we committed to a restructuring plan to optimize our operating model and cost structure which will be substantially implemented by the end of 2019. We expect to record total after-tax charges of approximately $150 million to $210 million during 2019. The charges under this plan primarily consist of employee severance, exit-related costs and other charges.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES
We consider an accounting estimate to be critical if the estimate requires us to make assumptions about matters that were uncertain at the time the accounting estimate was made and if different estimates that we reasonably could have used in the current period, or changes in the accounting estimate that are reasonably likely to occur from period to period, could have a material impact on our financial condition or results from operations. Below are the estimates that we believe are critical to the understanding of our operating results and financial condition. Other accounting policies are described in Financial Note 1, “Significant Accounting Policies,” to the consolidated financial statements appearing in this Annual Report on Form 10-K. Because of the uncertainty inherent in such estimates, actual results may differ from these estimates.
Allowance for Doubtful Accounts: We provide short-term credit and other customer financing arrangements to customers who purchase our products and services. Other customer financing primarily relates to guarantees provided to our customers, or their creditors, regarding the repurchase of inventories. We also provide financing to certain customers related to the purchase of pharmacies, which serve as collateral for the loans. We estimate the receivables for which we do not expect full collection based on historical collection rates and specific knowledge regarding the current creditworthiness of our customers and record an allowance in our consolidated financial statements for these amounts.
In determiningThe Company considers historical experience, the appropriatecurrent economic environment, customer credit ratings or bankruptcies, and reasonable and supportable forecasts to develop its allowance for doubtful accounts, which includes general and specific reserves,accounts. Management reviews these factors quarterly to determine if any adjustments are needed to the Company reviews accounts receivable aging, industry trends, customer financial strength, credit standing, historical write-off trends and payment historyallowance.

Sales to assess the probability of collection. If the frequency and severity of customer defaults due to our customers’ financial condition or general economic conditions change, our allowance for uncollectible accounts may require adjustment. As a result, we continuously monitor outstanding receivables and other customer financing and adjust allowances for accounts where collection may be in doubt. During 2018, sales to ourCompany’s ten largest customers, including group purchasing organizations (“GPOs”), accounted for approximately 51.7%51% of our total consolidated revenues.revenues in 2021 and comprised approximately 32% of total trade accounts receivable at March 31, 2021. Sales to our largest customer, CVS Health Corporation (“CVS”), accounted for approximately 19.9%21% of our total consolidated revenues. At March 31, 2018, trade accounts receivable from our ten largest customers wererevenues in 2021 and comprised approximately 24.9%19% of total trade accounts receivable. Accounts receivable from CVS were approximately 16.4% of total trade accounts receivable.at March 31, 2021. As a result, our sales and credit concentration is significant. We also have agreements with GPOs, each of which functions as a purchasing agent on behalf of member hospitals, pharmacies and other healthcare providers, as well as with government entities and agencies. The accounts receivables balances are with individual members of the GPOs, and therefore no significant concentration of credit risk exists. A material default in payment, a material reduction in purchases from these or any other large customers, or the loss of a large customer or GPO could have a material adverse impact on our financial position, results of operations, and liquidity.
Reserve methodologies are assessed annually based on historical losses and economic, business and market trends. In addition, reserves are reviewed quarterly and updated if unusual circumstances or trends are present. We believe the reserves maintained and expenses recorded in 20182021 are appropriate and consistent within the context of historical methodologies employed. At this time, we are not awareemployed, as well as assessment of any internal process or customer issues that might lead to a significant increase in our allowance for doubtful accounts as a percentage of net revenue in the foreseeable future.trends currently available.
At March 31, 2018,2021, trade and notes receivables were $14,480 million$17.5 billion prior to allowances of $187$211 million. In 2018, 20172021, 2020 and, 2016,2019, our provision for bad debts was $44$4 million, $93$91 million, and $113 million.$132 million, respectively. At March 31, 20182021 and 2017,2020, the allowance as a percentage of trade and notes receivables was 1.3%1.2% and 1.7%.1.4%, respectively. An increase or decrease of a hypothetical 0.1% in the 20182021 allowance as a percentage of trade and notes receivables would result in an increase or decrease in the provision for bad debts of approximately $14$18 million. The selected 0.1% hypothetical change does not reflect what could be considered the best or worst-case scenarios. Additional information concerning our allowance for doubtful accounts may be found in Schedule II included in this Annual Report on Form 10-K.

The LIFO method was used to value approximately 63%58% and 70%60% of our inventories at March 31, 20182021 and 2017.2020, respectively. If we had used the FIFOmoving average method of inventory valuation, inventories would have been approximately $906$406 million and $1,005$444 million higher than the amounts reported at March 31, 20182021 and 2017.2020, respectively. These amounts are equivalent to our LIFO reserves. The lower LIFO credits in 2021 compared to 2020 is primarily due to higher brand inflation and delays of branded off-patent to generic drug launches. Our LIFO valuation amount includes both pharmaceutical and non-pharmaceutical products. We recognized net LIFO credits of $99$38 million, $252 million, and $7$210 million, respectively, in 20182021, 2020, and 2017 and net LIFO charges2019 in our Consolidated Statements of $244 million in 2016 within our consolidated statements of operations.Operations. A LIFO charge is recognized when the net effect of price increases on pharmaceutical and non-pharmaceutical products held in inventory exceeds the impact of price declines, including the effect of branded pharmaceutical products that have lost market exclusivity. A LIFO credit is recognized when the net effect of price declines exceeds the impact of price increases on pharmaceutical and non-pharmaceutical products held in inventory. Excluding LIFO reserves, our inventory reserves as of March 31, 2021 and 2020 were $263 million and $96 million, respectively. The increase was primarily due to 2021 charges totaling $136 million on certain PPE and other related products due to inventory impairments and excess inventory within our Medical-Surgical Solutions segment.
We believe that the moving average inventory costing method provides a reasonable estimation of the current cost of replacing inventory (i.e., “market”). As such, our LIFO inventory is valued at the lower of LIFO or market. As of March 31, 20182021 and 2017,2020, inventories at LIFO did not exceed market.

FINANCIAL REVIEW (Continued)

In determining whether an inventory valuation allowance is required, we consider various factors including estimated quantities of slow-moving inventory by reviewing on-hand quantities, outstanding purchase obligations and forecasted sales. Shifts in market trends and conditions, changes in customer preferences due to the introduction of generic drugs or new pharmaceutical products or the loss of one or more significant customers are factors that could affect the value of our inventories. We write down inventories which are considered excess and obsolete as a result of these reviews. These factors could make our estimates of inventory valuation differ from actual results.
Business Combinations: We accountThe Company accounts for acquired businessesbusiness combinations using the acquisition method of accounting which requireswhereby the identifiable assets and liabilities of the acquired business, as well as any noncontrolling interest in the acquired business, are recorded at their estimated fair values as of the date that oncethe Company obtains control of a business is obtained, 100% of the assets acquired and liabilities assumed, including amounts attributed to noncontrolling interests, be recorded at the date of acquisition at their respective fair values.business. Any purchase consideration in excess of the purchase price over the estimated fair values of the net assets acquired is recorded as goodwill. Acquisition-related expenses and related restructuring costs are expensed as incurred.
Several valuation methods may be used to determine the fair value of assets acquired and liabilities assumed. For intangible assets, we typically use a method that is a form or variation of the income method. This method starts withapproach, whereby a forecast of all of the expected future net cash flows associated with each asset. These cash flowsattributable to the asset are then adjusteddiscounted to present value by applying an appropriateusing a risk-adjusted discount rate that reflects the risk factors associated with the cash flow streams.rate. Some of the more significant estimates and assumptions inherent in the income method or other methodsapproach include the amount and timing of projected future cash flows, the discount rate selected to measure the risks inherent in the future cash flows and the assessment of the asset’s life cycle and the competitive trends impacting the asset, including consideration of any technical, legal, regulatory, or economic barriers to entry. Determining theexpected useful life of an intangible asset also requires judgment as different types of intangible assets will have different useful lives.life. Refer to Financial Note 6,5, “Business Combinations,Acquisitions and Divestitures,” to the consolidated financial statements appearingincluded in this Annual Report on Form 10-K for additional information regarding our acquisitions.
Goodwill and Long-Lived Assets: As a result of acquiring businesses, we have $10,924 million$9.5 billion and $10,586 million$9.4 billion of goodwill at March 31, 20182021 and 2017, $4,102 million2020, respectively, and $3,665 million$2.9 billion and $3.2 billion of intangible assets, net at March 31, 20182021 and 2017.2020, respectively. We perform an impairment test on goodwill balances annually in the fourththird quarter orand more frequently if indicators for potential impairment exist. Indicators that are considered include significant declines in performance relative to expected operating results, significant changes in the use of the assets, significant negative industry or economic trends, or a significant decline in the Company’s stock price and/or market capitalization for a sustained period of time.
Goodwill impairment testing is conducted at the reporting unit level, which is generally defined as an operating segment or a component, one level below our Distribution Solutions and Technology Solutions operating segments, for which discrete financial information is available and segment management regularly reviews the operating results of that reporting unit.
In 2018, we elected to early adopt on a prospective basis,We apply the amended guidance that simplifies goodwill impairment testingtest by eliminatingcomparing the second step of the impairment test. The one-step impairment test under the amended guidance requires an entity to compare theestimated fair value of a reporting unit withto its carrying amountvalue and recognizesrecording an impairment charge forequal to the amount by whichof excess carrying value above the carrying amount exceeds the reporting unit’sestimated fair value, if any.

goodwill allocated to the reporting unit.
To estimate the fair value of our reporting units, we generally use a combination of the market approach and the income approach. Under the market approach, we estimate fair value by comparing the business to similar businesses, or guideline companies whose securities are actively traded in public markets. Under the income approach, we use a discounted cash flow (“DCF”) model in which cash flows anticipated over several periods, plus a terminal value at the end of that time horizon, are discounted to their present value using an appropriate expected rate of return.that is commensurate with the risk inherent within the reporting unit. In addition, we compare the aggregate of the reporting units’ fair values to our market capitalization as further corroboration of the fair values.

FINANCIAL REVIEW (Continued)

Estimates of fair value result from a complex series of judgments about future events and uncertainties and rely heavily on estimates and assumptions at a point in time. Judgments made in determining an estimate of fair value may materially impact our results of operations. The valuations are based on information available as of the impairment reviewtesting date and are based on expectations and assumptions that have been deemed reasonable by management. Any material changes in key assumptions, including failure to meet business plans, negative changes in government reimbursement rates, deterioration in the U.S. and global financial markets, an increase in interest raterates or an increase in the cost of equity financing by market participants within the industry or other unanticipated events and circumstances, may decrease the projected cash flows or increase the discount rates and could potentially result in an impairment charge. For example, some ofUnder the moremarket approach, significant estimates and assumptions inherent in the goodwill impairment estimation process using the market approachalso include the selection of appropriate guideline companies and the determination of market valueappropriate valuation multiples for both the guideline companies andto apply to the reporting unit, the determination of applicable premiums and discounts based on any differences in marketability between the business and the guideline companies and for the income approach, the required rate of return used in the DCF method, which reflects capital market conditions and the specific risks associated with the business.unit.

IncreasesAn increase in the unsystematic risk premium increases the discount rate.
In 2016, we concluded that there were no impairmentsBased on the 2019 annual goodwill impairment tests, the estimated fair values of our reporting units, excluding the Europe Retail Pharmacy and Europe Pharmaceutical Distribution reporting units in our International segment, exceeded their carrying values. The impairment testing performed in 2020 did not indicate any material impairment of goodwill. The segment change in the second quarter of 2021 prompted changes in multiple reporting units across the Company. As a result, goodwill included in impacted reporting units was reallocated using a relative fair value approach and assessed for impairment both before and after the reallocation. We recorded a goodwill impairment charge of $69 million in 2021 as the estimated fair value of the Europe Retail Pharmacy reporting unit was lower than its reassigned carrying value based on changes in the composition of the Europe Retail Pharmacy reporting unit within the International segment. At March 31, 2021, the balance of goodwill for the reporting units in Europe was approximately nil and the remaining balance of goodwill in the International segment primarily relates to one of our reporting units in Canada.
The estimated fair values of our McKesson Canada reporting unit in our International segment and our RxCrossroads reporting unit in our RxTS segment exceeded the carrying values of these reporting units by 11% and 14%, respectively, in 2021. The goodwill balance of these reporting units was $1.5 billion for McKesson Canada and $312 million for RxCrossroads at March 31, 2021 or approximately 19% of the consolidated goodwill balance. Generally, a decline in estimated future cash flows in excess of 16% for McKesson Canada and 17% for RxCrossroads or an increase in the discount rate in excess of approximately 1.5% could result in an indication of goodwill impairment for these reporting units in future reporting periods. Other risks, expenses and future developments, such as additional government actions, increased regulatory uncertainty, and material changes in key market assumptions that we were unable to anticipate as of the testing date may require us to further revise the projected cash flows, which could adversely affect the fair value of eachour other reporting unit exceeded its carrying value. In 2017, we recorded a non-cash charge to impair the carrying value of our EIS reporting unit’s goodwill. In 2018, we recorded non-cash charges to impair the carrying value of goodwill balance for our McKesson Europe and Rexall Health reporting units.units in future periods. Refer to Financial Note 3,12, “Goodwill Impairment Charges”and Intangible Assets, Net,” to the consolidated financial statements appearing in this Annual Report on Form 10-K for additional information.
Commencing in the first quarter of 2019, our operating structure will be realigned into three reportable segments, U.S. Pharmaceutical and Specialty Solutions, European Pharmaceutical Solutions and Medical-Surgical Solutions. All remaining operating segments and business activities that are not significant enough to be reportable segments are combined into Other.
This change in our operating segment structure will result in two new reporting units within the European Pharmaceutical Solutions segment. As a result, we will be required to perform a goodwill impairment test for the impacted new reporting units immediately before and after the segment change. While we believe the assumptions used in our 2018 impairment analysis are reasonable and representative of expected results for our 2018 reporting unit structure, we may recognize an additional goodwill impairment charge immediately after the segment change as the reassigned carrying values of the reporting units may exceed their respective estimated fair values. We are currently evaluating the impact and are unable to reasonably estimate the additional goodwill impairment charge upon the segment change. At March 31, 2018, the total remaining goodwill balance for these two reporting units was $1,851 million.  
A further decrease in the estimated future cash flows, an increase in the discount rate and/or a decrease in the terminal growth rate, could also result in an additional goodwill impairment charge for these reporting units.

Currently, all of our intangible and other long-lived assets are amortized or depreciated based on the pattern of their economic consumption or on a straight-line basis over their estimated useful lives, ranging from one to 38 years. We review intangible assets for impairment at an asset group level whenever events or changes in circumstances indicate that the carrying value of the assets may not be recoverable. Determination of recoverability of intangible assets is based on the lowest level of identifiable estimated future undiscounted cash flows resulting from use of the asset and its eventual disposition. Measurement of any impairment loss is based on the excess of the carrying value of the asset group over its fair value. Assumptions and estimates about future values and remaining useful lives of our purchased intangible assets are complex and subjective. They can be affected by a variety of factors, including external factors such as industry and economic trends, and internal factors such as changes in our business strategy and our internal forecasts. During 2018, we performed an impairment test of intangible and other long-lived assets, and recognized non-cash asset impairment charges of $479 million pre-tax ($443 million after-tax) for McKesson Europe and Rexall Health businesses to impair the carrying value of certain intangible and other long-lived assets. We utilized an income approach (DCF method) or a combination of an income approach and a market approach for estimating the fair value of intangible assets. The fair value of the intangible assets is considered a Level 3 fair value measurement due to the significance of unobservable inputs developed using company specific information. There were no material impairments of intangibles and other long-lived assets in 2017 or 2016 within our continuing operations. 
Our ongoing consideration of all the factors described previously could result in further impairment charges in the future, which could adversely affect our net income. Refer to Financial Note 4, “Restructuring, Impairment, and Asset ImpairmentRelated Charges” to the consolidated financial statements appearing in this Annual Report on Form 10-K for additional information.
Supplier Reserves: We establish reserves against amounts due from suppliers relating to various price and rebate incentives, including deductions or billings taken against payments otherwise due to them. These reserve estimates are established based on judgment after considering the status

Valuation of Equity Method Investments: We evaluate our investments for other-than-temporary impairments when circumstances indicate those assets may be impaired. When the amounts due from suppliers ondecline in value is deemed to be other than temporary, an impairment is recognized to the extent that the fair value is less than the carrying value of the investment. We consider various factors in determining whether a continual basisloss in value of an investment is other than temporary including: the length of time and adjust the reserveextent to which the fair value has been below cost, the financial condition of the investees, and our intent and ability to retain the investment for a period of time sufficient to allow for recovery of value. Management makes certain judgments and estimates when appropriate based onin its assessment including but not limited to: identifying if circumstances indicate a decline in value is other than temporary, expectations about the business operations of investees, as well as industry, financial, and market factors. Any significant changes in factual circumstances. As of March 31, 2018 and 2017, supplier reserves were $227 million and $201 million. The final outcome of any outstanding claims may differ from our estimate. All of the supplier reserves at March 31, 2018 and 2017 pertain to our Distribution Solutions segment. An increaseassumptions or decreasejudgments in the supplier reserve as a hypothetical 0.1% of trade payables at March 31, 2018 wouldassessing impairments could result in an increaseimpairment charge.
Restructuring Charges: We have certain restructuring reserves which require significant estimates related to the timing and amount of future employee severance and other exit-related costs to be incurred when the restructuring actions take place. We generally recognize employee severance costs when payments are probable and amounts are estimable. Costs related to contracts without future benefit or decreasecontract termination are recognized at the earlier of the contract termination or the cease-use dates. Other exit-related costs are recognized as incurred. In connection with these restructuring actions, we also assess the recoverability of long-lived assets used in the costbusiness, and as a result, we may recognize accelerated depreciation and amortization reflecting shortened useful lives of sales of approximately $32 million in 2018. The selected 0.1% hypothetical change does not reflect what could be considered the best or worst case scenarios.underlying assets.
Income Taxes: Our income tax expense and deferred tax assets and liabilities reflect management’s best assessment of estimated current and future taxes to be paid. We are subject to income taxes in the U.S. and numerous foreign jurisdictions. Significant judgments and estimates are required in determining the consolidated income tax provision and in evaluating income tax uncertainties.uncertainties and include those used to conclude on the tax-free nature of the separation of the Change Healthcare JV and the unrecognized tax position related to opioid-related litigation and claims, which remains unfinalized, and which may differ from the actual amounts of tax benefit recognized. We review our tax positions at the end of each quarter and adjust the balances as new information becomes available.
Deferred income taxes arise from temporary differences between the tax and financial statement recognition of revenue and expense. In evaluating our ability to recover our deferred tax assets, we consider all available positive and negative evidence including our past operating results, the existence of cumulative net operating losses in the most recent years, and our forecast of future taxable income. In estimating future taxable income, we develop assumptions including the amount of future federal, state and foreign pre-tax operating income, the reversal of temporary differences, and the implementation of feasible and prudent tax planning strategies. These assumptions require significant judgment about the forecasts of future taxable income and are consistent with the plans and estimates we use to manage the underlying businesses.
Changes in tax laws and rates could also affect recorded deferred tax assets and liabilities in the future. Should tax laws change, including those laws pertaining to LIFO, our tax expense and cash flows could be materially impacted.
In addition, the calculation of our tax liabilities includes estimates for uncertainties in the application of complex new tax regulations across multiple global jurisdictions where we conduct our operations. For example, on December 22, 2017, the U.S. government enacted comprehensive new tax legislation referred to as the 2017 Tax Act. The 2017 Tax Act makes broad and complex changes to the U.S. tax code. Although our accounting for the impact of the 2017 Tax Act is incomplete, we have made estimates based on management judgment and recorded provisional amounts. Refer to Financial Note 10, “Income Taxes,” to the accompanying consolidated financial statements appearing in this Annual Report on Form 10‑K for additional information.

We recognize liabilities for tax and related interest for issues in the U.S. and other tax jurisdictions based on our estimate of whether, and the extent to which, additional taxes and related interest will be due. If our current estimate of tax and interest liabilities is less than the ultimate settlement, an additional charge to income tax expense may result. If our current estimate of tax and interest liabilities is more than the ultimate settlement, a reduction to income tax expense may be recognized.
Loss Contingencies: We are subject to various claims, including claims with customers and vendors, pending and potential legal actions for damages, investigations relating to governmental laws and regulations and other matters arising out of the normal conduct of our business. When a loss is considered probable and reasonably estimable, we record a liability in the amount of our best estimate for the ultimate loss. However, the likelihood of a loss with respect to a particular contingency is often difficult to predict and determining a meaningful estimate of the loss or a range of loss may not be practicable based on the information available and the potential effect of future events and decisions by third parties that will determine the ultimate resolution of the contingency. Moreover, it is not uncommon for such matters to be resolved over many years, during which time relevant developments and new information must be reevaluated at least quarterly to determine both the likelihood of potential loss and whether it is possible to reasonably estimate a range of possible loss. When a material loss is reasonably possible or probable but a reasonable estimate cannot be made, disclosure of the proceeding is provided. Legal fees are recognized as incurred when the legal services are provided.
Disclosure is also provided when it is reasonably possible that a loss will be incurred or when it is reasonably possible that the amount

We review all contingencies at least quarterly to determine whether the likelihood of loss has changed and to assess whether a reasonable estimate of the potential loss or range of the loss can be made. As discussed above, development of a meaningful estimate of loss or a range of potential loss is complex when the outcome is directly dependent on future negotiations with or decisions by third parties, such as regulatory agencies, the court system and other interested parties. Such factors bear directly on whether itIn conjunction with the preparation of the accompanying financial statements, we considered matters related to ongoing controlled substances claims to which we are a party. As a result of ongoing, advanced discussions with state attorneys general and plaintiffs’ representatives regarding a framework to resolve the claims of governmental entities, and our assessment of certain other opioid-related claims, we have reached a stage at which a broad settlement of opioid claims by governmental entities is probable and recorded a charge of $8.1 billion for the year ended March 31, 2021 within “Claims and litigation charges, net” in our Consolidated Statement of Operations in this report. Because of the many uncertainties associated with any potential settlement arrangement or other resolution of opioid-related litigation, including the uncertainty of the scope of participation by plaintiffs in any potential settlement, we are not able to reasonably estimate the upper or lower ends of the range of ultimate possible loss for all opioid-related litigation matters. While we are not able to predict the outcome or reasonably estimate a range of potential losspossible losses in these matters, an adverse judgment or negotiated resolution in any of these matters could have a material adverse effect on our results of operations, consolidated financial position, cash flows or liquidity.

(3)$8 million was accrued within “Other accrued liabilities” on our Consolidated Balance Sheet as of March 31, 2021 for share repurchases that were executed in late March and settled in early April.
During the last three years, our share repurchases were transacted through both open market transactions and ASR programs with third party financial institutions.
In 2019, we retired 5.0 million or $542 million of the Company’s treasury shares previously repurchased. Under the applicable state law, these shares resume the status of authorized and unissued shares upon retirement. In accordance with our accounting policy, we allocate any excess of share repurchase price over par value between additional paid-in capital and retained earnings. Accordingly, our retained earnings and additional paid-in capital were reduced by $472 million and $70 million during 2019, respectively.
On March 9, 2020, we completed the Split-off of our interest in the Change Healthcare JV. In connection with the Split-off, we distributed all 176.0 million outstanding shares of SpinCo common stock, which held all of the Company’s interests in the Change Healthcare JV, to participating holders of the Company’s common stock in exchange for 15.4 million shares of McKesson stock, which are now held as treasury stock on our consolidated balance sheet. Following consummation of the exchange offer, on March 10, 2020, SpinCo merged with and into Change and each share of SpinCo common stock was converted into one share of Change common stock, par value $0.001 per share, with cash being paid in lieu of fractional shares of Change common stock. See Note 2, “Investment in Change Healthcare Joint Venture” to the accompanying consolidated financial statements included in this Annual Report on Form 10-K for more information.
The total authorization outstanding for repurchase of the Company’s common stock up to $4was $2.8 billion in October 2016. In 2016, we repurchased 8.7 million of our shares through a combination of an ASR program and open market transactions. In 2017, we repurchased 14.1 million of our shares through open market transactions and 1.4 million of our shares through an ASR program. We received 0.3 million additional shares in April 2017 for the 2017 ASR program. In 2018, we repurchased 3.5 million of our shares through open market transactions and 6.7 million of our shares through ASR programs. We received an additional 0.5 million shares in April 2018 under the March 2018 ASR program.

Our cash and cash equivalents balance as of March 31, 2021 and 2020 included approximately $2.3 billion and $1.7 billion of cash held by our subsidiaries outside of the U.S., respectively. Our primary intent is to utilize this cash for foreign operations for an indefinite period of time. Although the vast majority of cash held outside the U.S. is available for repatriation, doing so could subject us to foreign withholding taxes and state income taxes. Following enactment of the 2017 Tax Cuts and Jobs Act, the repatriation of cash to the U.S. is generally no longer taxable for federal income tax purposes.
Working capital primarily includes cash and cash equivalents, receivables, and inventories, net of drafts and accounts payable, short-term borrowings, current portion of long-term debt, deferred revenue and other current liabilities. Our Distribution Solutions segment requires abusinesses require substantial investmentinvestments in working capital that isare susceptible to large variations during the year as a result of inventory purchase patterns and seasonal demands. Inventory purchase activity is a function of sales activity and other requirements. The COVID-19 pandemic has potential to increase the variations in our working capital, which we continue to monitor closely.

Our debt to capital ratio increased for 2018the year ended March 31, 2021 primarily due to a decrease in stockholders’ equity driven by net loss for the year and decreasedshare repurchases. Our unfavorable return on McKesson’s stockholder’s equity (deficit) as of March 31, 2021 was also driven by net loss for 2017the year. Net loss for the year ended March 31, 2021 includes an after-tax non-cash charge of $6.8 billion related to our estimated liability for opioid-related claims, as discussed in “Trends and Uncertainties” of this Financial Review and Financial Note 19, “Commitments and Contingent Liabilities,” to the accompanying consolidated financial statements included in this Annual Report on Form 10‑K.

Upon the effectiveness of the Domination Agreement on December 2, 2014, the noncontrolling shareholders of McKesson Europe received a put right that enables them to put their McKesson Europe shares to McKesson at €22.99 per share, which price is increased annually for interest in the amount of 5 percentage points above a base rate published semiannually by the German Bundesbank, less any compensation amount or guaranteed dividend already paid (“Put Amount”).  The redemption value is the Put Amount adjusted for exchange rate fluctuations each period. The ultimate amountcarrying value of redeemable noncontrolling interests is also adjusted each period for the portion of other comprehensive income attributable to the noncontrolling shareholders, which is primarily due to changes in foreign currency exchange rates.

In future periods, unfavorable foreign currency exchange rate fluctuations between the Euro and the U.S. dollar could adversely impact the carrying value of our redeemable noncontrolling interests and require an adjustment to increase the balance of our redeemable noncontrolling interests to its maximum redemption value. Such adjustments would be recorded in “Net income attributable to noncontrolling interests” in our consolidated statements of operations.
Additionally, we are obligated to pay an annual recurring compensation of €0.83 per McKesson Europe share (the “Compensation Amount”) to the noncontrolling shareholders of McKesson Europe under the Domination Agreement, which became effective in December 2014.Agreement.

Interest rate risk: Our long-term debt bears interest predominately at fixed rates, whereas our short-term borrowings are at variable interest rates.
Our cash and cash equivalents balances earn interest at variable rates.

Changes in foreign currency exchange rates could have a material adverse impact on our financial results that are reported in U.S. dollars. We are also exposed to foreign exchange rate risk related to our foreign subsidiaries, including intercompany loans denominated in non-functional currencies.
We have certain foreign exchange rate risk programs that use foreign currency forward contracts and cross-currency swaps. The forward contracts and cross-currency swaps are designatedintended to reduce the income statement effects from fluctuations in foreign exchange rates and have been designated as cash flow hedges. These programs reduce but do not entirely eliminate foreign exchange risk.
As of March 31, 20182021 and 2017,2020, the effect of a hypothetical adverse 10% change in the underlying foreign currency exchange rates would have impacted the fair value of our foreign exchange contracts by approximately $458$267 million and $357 million.$435 million, respectively. However, our risk management programs are designed such that the potential loss in value of these risk management portfolios described above would be largely offset by changes in the value of the underlying exposure. Refer to Financial Note 20,16, “Hedging Activities,” for more information on our foreign currency forward contracts and cross-currency swaps.

Opinions on the Financial Statements and Internal Control over Financial Reporting


We have audited the accompanying consolidated balance sheets of McKesson Corporation and subsidiaries (the “Company”) as of March 31, 20182021 and 2017,2020, the related consolidated statements of operations, comprehensive income (loss), stockholders’ equity, and cash flows, for each of the three years in the period ended March 31, 2018,2021, and the related notes and the schedule listed in the Index at Item 15 (collectively referred to as the “financial statements”). We also have audited the Company’s internal control over financial reporting as of March 31, 2018,2021, based on criteria established in Internal Control—Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”).
In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of the Company as of March 31, 20182021 and 2017,2020, and the results of its operations and its cash flows for each of the three years in the period ended March 31, 2018,2021, in conformity with accounting principles generally accepted in the United States of America. Also, in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of March 31, 2018,2021, based on criteria established in Internal Control - Integrated Framework (2013) issued by COSO.
Change in Accounting Principle
As discussed in Note 11 to the financial statements, effective April 1, 2019, the Company adopted the Financial Accounting Standards Board’s (“FASB”) new standard related to leases using the modified retrospective basis.
Basis for Opinions
The Company’s management is responsible for these financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Annual Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on these financial statements and an opinion on the Company’s internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.
Our audits of the financial statements included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures to respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

Definition and Limitations of Internal Control over Financial Reporting
A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

McKESSON CORPORATION

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Critical Audit Matters
The critical audit matters communicated below are matters arising from the current-period audit of the financial statements that were communicated or required to be communicated to the audit committee and that (1) relate to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.
Contingent Liabilities - Broad Settlement of Opioid Claims brought by Governmental Entities - Refer to Note 1 and Note 19 to the financial statements
Critical Audit Matter Description
The Company and its affiliates are defendants in many cases asserting claims related to distribution of controlled substances, including opioids. The Company is named as a defendant along with other pharmaceutical wholesale distributors, pharmaceutical manufacturers and retail pharmacy chains. The plaintiffs in these actions include state attorneys general, county and municipal governments, hospitals, tribal nations, health and welfare funds, third-party payors and individuals. The Company is in ongoing, advanced discussions with state attorneys general and plaintiffs’ representatives, who represent states, their political subdivisions and other government entities (“governmental entities”), regarding a framework under which the three largest U.S. pharmaceutical distributors would pay up to approximately $21.0 billion over a period of 18 years, with up to approximately $8.0 billion to be paid by the Company to resolve the claims brought by governmental entities (“broad settlement of opioid claims”). When a loss is considered probable and reasonably estimable, the Company records a liability in the amount of its estimate for the ultimate loss. The Company reviews all loss contingencies at least quarterly to determine whether the likelihood of loss has changed and to assess whether a reasonable estimate of the loss or range of loss can be made. The Company also performs an assessment of loss contingencies where a loss is reasonably possible. If it is reasonably possible that a loss may have been incurred and the effect on the financial statements could be material, the Company discloses the nature of the loss contingency and an estimate of the possible loss or range of loss or a statement that such an estimate cannot be made within the notes to the financial statements. For the year ended March 31, 2021, management believes that a loss through broad settlement of opioid claims brought by governmental entities is both probable and reasonably estimable, and accordingly, recorded a charge in the amount of $8.0 billion, which represents management’s best estimate of future loss related to these specific matters.
We identified the potential broad settlement of opioid claims as a critical audit matter because of the significant judgment and challenges auditing management’s determination of whether such loss is probable and reasonably estimable. Specifically, auditing management’s determination and disclosure of whether the contingent loss arising from the potential broad settlement of opioid claims is probable, and the related measurement of such loss, is subjective and requires significant judgment given that the potential loss is based upon settlement terms that have not yet been finalized.

Table of Contents
McKESSON CORPORATION
How the Critical Audit Matter Was Addressed in the Audit
Our audit procedures related to the potential broad settlement of opioid claims included the following, among others:
We tested the effectiveness of internal controls related to the potential broad settlement of opioid claims, and approval of the accounting treatment and related disclosures based on the most recent facts and circumstances.
We inquired of the Company’s internal and external legal counsel, as well as executives and other members of management, to understand the basis for the Company’s conclusion that a loss related to a potential broad settlement of opioid claims, is probable and reasonably estimable as of March 31, 2021. In addition, we inspected responses to inquiry letters sent to both internal and external legal counsel as it relates to the status of discussions with plaintiffs’ counsel and the Company’s intent regarding the framework for a potential broad settlement of opioid claims.
We evaluated management’s analysis of the potential broad settlement of opioid claims, including the methodology used by management to determine the probability of such loss. We also evaluated the methodology used by management to estimate the most likely loss to be incurred by the Company as a result of a potential broad settlement of opioid claims.
We examined Board of Directors meeting minutes, including relevant sub-committee meeting minutes, held inquiries with a director serving on the sub-committee, and compared to internal and external counsel’s written responses to our inquiry letters.
We performed public domain searches for evidence contrary to management’s analysis.
With the assistance of our specialists in accounting for loss contingencies, we evaluated the facts, evidence and the Company’s related accounting treatment for the potential broad settlement of opioid claims.
We evaluated any events subsequent to March 31, 2021 that might impact our evaluation of the potential broad settlement of opioid claims.
We obtained written representations from executives and internal counsel of the Company.
We examined proposed terms related to the potential broad settlement framework.
We evaluated the Company’s related disclosures for consistency with our testing.
Uncertain Tax Position - Broad Settlement of Opioid Claims brought by Governmental Entities - Refer to Note 1 and Note 8 to the financial statements
Critical Audit Matter Description
For the year ended March 31, 2021, the Company recognized $1.3 billion of tax benefit related to a potential broad settlement of opioid claims and had an additional $0.5 billion of potential benefit relating to an uncertain tax position that had not been recognized. Tax benefits from uncertain tax positions are recognized when it is more likely than not that the position will be sustained upon examination, including resolutions of any related appeals or litigation processes, based on the technical merits. The net amount recognized by management is measured as the largest amount of tax benefit that is greater than 50 percent likely of being realized. The Company uses significant judgment in evaluating the technical tax merits of income tax benefits that qualify for recognition, including the determination of the amount that is more likely than not of being realized for U.S. federal and state income tax purposes.
We identified the Company’s uncertain tax position related to the charge for the potential broad settlement of opioid claims as a critical audit matter because of the challenges in auditing management’s estimate of the amount of income tax benefit that qualifies for recognition. Specifically, auditing management’s uncertain tax position in this area was challenging because the assumptions and estimates involved in management’s analysis required significant judgment as they are based upon the potential terms of a broad settlement, including provisions related to deductibility, that have not yet been finalized. There is also significant judgment associated with the assessment of the technical tax merits of such a settlement, including the related interpretation of applicable tax laws and regulations.

How the Critical Audit Matter Was Addressed in the Audit
Our audit procedures related to the Company's uncertain tax position associated with a potential broad settlement of opioid claims included the following, among others:
We tested the effectiveness of internal controls related to the Company’s assessment of the technical merits of its tax position, including the Company’s assessment as to the amount of benefit that is more likely than not to be realized.
With the assistance of our tax specialists, we evaluated the facts, evidence and the Company’s related income tax analysis for the charge related to the potential broad settlement of opioid claims, including assumptions used by management to measure the related recognized and unrecognized tax benefits.
We inquired of the Company’s internal and external legal counsel to understand the basis for the Company’s conclusion that a portion of the potential broad settlement of opioid claims would be deductible based on the most recent discussions with plaintiffs’ counsel.
We held inquiries with the Company’s external income tax advisors and we also read and evaluated management’s documentation of information received from these external advisors, which informed the basis of management’s position related to the uncertain tax position associated with the potential broad settlement of opioid claims.
We compared management's income tax assessment of this matter to the treatment of other recorded opioid charges to evaluate the consistency of the Company’s judgments related to the uncertain tax position.
We evaluated any events subsequent to March 31, 2021 that might impact our evaluation of the Company’s uncertain tax position related to the charge for the potential broad settlement of opioid claims.
We obtained written representations from executives and internal counsel of the Company.
We examined proposed terms related to the potential broad settlement framework.
We evaluated the Company’s related disclosures for consistency with our testing and also searched for contradictory evidence by reading disclosures from peer companies, who are also party to the potential broad settlement of opioid claims.
Goodwill - Refer to Note 1 and Note 12 to the financial statements
Critical Audit Matter Description
The Company’s evaluation of goodwill for impairment involves comparing the carrying amount of each reporting unit to its fair value on the first day of the third fiscal quarter or whenever the Company believes a potential indicator of impairment requiring a more frequent assessment has occurred. The Company uses a combination of the income and market approaches to estimate reporting unit fair value. Under the market approach, fair value is estimated by comparing the business to similar businesses, or guideline companies whose securities are actively traded in public markets. Under the income approach, the Company uses a discounted cash flow (“DCF”) model where cash flows anticipated over future periods, plus a terminal value at the end of that time horizon, are discounted to their present value using an appropriate rate that is commensurate with the risk inherent within the reporting unit. The rate used to discount to present value includes an unsystematic risk premium, which is intended to address uncertainty related to the reporting unit’s future cash flow projections. The goodwill balance was $9.5 billion as of March 31, 2021, of which $1.5 billion was allocated to the McKesson Canada reporting unit. The fair value of all reporting units exceeded their respective carrying amounts as of the measurement date and, therefore, no impairment was recognized.
We identified the estimation of the fair value of the McKesson Canada reporting unit used to evaluate the recoverability of goodwill as a critical audit matter because of the challenges auditing significant judgments used in the selection of a discount rate, including the unsystematic risk premium. In particular, the fair value estimate is sensitive to the unsystematic risk premium assumption, which is affected by expected risk of changes in the Canadian business and regulatory environments. Auditing management’s selected discount rate required a high degree of auditor judgment and an increased extent of effort, including the need to involve more senior members of the team and our fair value specialists.

How the Critical Audit Matter Was Addressed in the Audit
Our audit procedures related to the Company’s selection of a discount rate, including consideration of the unsystematic risk premium, for the McKesson Canada reporting unit included the following, among others:
We tested the effectiveness of internal controls related to management’s goodwill impairment evaluation, including those related to the selection of a discount rate and consideration of an unsystematic risk premium.
We evaluated management’s ability to accurately forecast operating results for the McKesson Canada reporting unit by comparing actual results to management’s historical forecasts, in order to consider the reasonableness and adequacy of management’s selected unsystematic risk premium.
As part of our assessment of the unsystematic risk premium, we evaluated the reasonableness of strategic plans expected to be implemented during the forecast period by comparing the forecasts to:
Actual results of historical strategic plans
Internal communications to management and the Board of Directors
With the assistance of our fair value specialists, we evaluated the reasonableness of the discount rate, including the unsystematic risk premium, by developing a range of independent estimates, testing the mathematical accuracy of the calculation and comparing to the discount rate selected by management.

We consolidateThe Company consolidates VIEs when it is determined that we areit is the primary beneficiary of the VIE. Investments in business entities in which the Company does not have control but has the ability to exercise significant influence over operating and financial policies, are accounted for using the equity method.
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: Certain prior year amounts have been reclassified to conform to the current year presentation.
Use of Estimates: The preparation of financial statements in conformity with U.S. GAAP requires that wethe Company make estimates and assumptions that affect the reported amounts in the consolidated financial statements and accompanying notes. Actual amounts could differ from those estimated amounts. The severity, magnitude and duration, as well as the economic consequences of the coronavirus diseases 2019 (“COVID-19”) pandemic, are uncertain, rapidly changing, and difficult to predict. Therefore, the Company’s accounting estimates and assumptions may change over time in response to COVID-19 and may change materially in future periods.
The Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) was enacted on March 27, 2020 in the U.S., and includes several provisions related to employment and income taxes, including provisions for the deferral of the employer portion of social security taxes through December 31, 2020. On December 27, 2020, the U.S. government enacted the Consolidated Appropriations Act, 2021, which enhances and expands certain provisions of the CARES Act. These legislative acts are not expected to have a material impact on the Company’s consolidated financial results.
Cash and Cash Equivalents: All highly liquid debt and money market instruments purchased with an original maturity of three months or less at the date of acquisition are included in cash and cash equivalents.
Cash equivalents are carried at fair value.

At March 31, 2018, trade accounts receivable from our ten largest customers wererevenues in 2021 and comprised approximately 24.9%19% of total trade accounts receivable. Accounts receivable from CVS were approximately 16.4% of total trade accounts receivable.at March 31, 2021. As a result, ourthe Company’s sales and credit concentration is significant. We also haveThe Company has agreements with GPOs, each of which functions as a purchasing agent on behalf of member hospitals, pharmacies and other healthcare providers, as well as with government entities and agencies. The accounts receivables balances are with individual members of the GPOs, and therefore no significant concentration of credit risk exists. A material default in payment, a material reduction in purchases from these or any other large customers, or the loss of a large customer or customer groups could have a material adverse impact on ourthe Company’s financial condition, results of operations, and liquidity. In addition, trade receivables are subject to concentrations of credit risk with customers in the institutional, retail, and healthcare provider sectors, which can be affected by a downturn in the economy and changes in reimbursement policies. This credit risk is mitigated by the size and diversity of the Company’s customer base as well as its geographic dispersion. We estimate the receivables for which we do not expect full collection based on historical collection rates and ongoing evaluations of the creditworthiness of our customers. An allowance is recorded in our consolidated financial statements for these estimated amounts.

The LIFO method was used to value approximately 63%58% and 70%60% of ourthe Company’s inventories at March 31, 20182021 and 2017.2020, respectively. If wethe Company had used the FIFOmoving average method of inventory valuation, inventories would have been approximately $906$406 million and $1,005$444 million higher than the amounts reported at March 31, 20182021 and 2017.2020, respectively. These amounts are equivalent to ourthe Company’s LIFO reserves. OurThe Company’s LIFO valuation amount includes both pharmaceutical and non-pharmaceutical products. WeThe Company recognized LIFO credits of $99$38 million, $252 million, and $7$210 million in 20182021, 2020, and 20172019, respectively, in “Cost of sales” in its Consolidated Statements of Operations. The lower LIFO credits in 2021 compared to 2020 is primarily due to higher brand inflation and net LIFO chargesdelays of $244 million in 2016 in cost of sales within our consolidated statements of operations.branded off-patent to generic drug launches. A LIFO charge is recognized when the net effect of price increases on pharmaceutical and non-pharmaceutical products held in inventory exceeds the impact of price declines, including the effect of branded pharmaceutical products that have lost market exclusivity. A LIFO credit is recognized when the net effect of price declines exceeds the impact of price increases on pharmaceutical and non-pharmaceutical products held in inventory. Excluding LIFO reserves, inventory reserves as of March 31, 2021 and 2020 were $263 million and $96 million, respectively. The increase was primarily due to charges in 2021 totaling $136 million on certain personal protective equipment and other related products due to inventory impairments and excess inventory within our Medical-Surgical Solutions segment. These charges are recorded in "Cost of sales" in the Consolidated Statements of Operations.
We believeThe Company believes that the moving average inventory costing method provides a reasonable estimation of the current cost of replacing inventory (i.e., “market”). As such, ourits LIFO inventory is valued at the lower of LIFO cost or market. As of March 31, 20182021 and 2017,2020, inventories at LIFO did not exceed market.

Held for Sale: Assets and 2016.liabilities to be disposed of by sale (“disposal groups”) are reclassified into “held for sale” if their carrying amounts are principally expected to be recovered through a sale transaction rather than through continuing use. The reclassification occurs when the disposal group is available for immediate sale and the sale is highly probable. These criteria are generally met when an agreement to sell exists, or management has committed to a plan to sell the assets within one year. Disposal groups are measured at the lower of carrying amount or fair value less costs to sell and are not depreciated or amortized. When the net realizable value of a disposal group increases during a period, a gain can be recognized to the extent that it does not increase the value of the disposal group beyond its original carrying value when the disposal group was reclassified as held for sale. The fair value of a disposal group, less any costs to sell, is assessed each reporting period it remains classified as held for sale and any remeasurement to the lower of carrying value or fair value less costs to sell is reported as an adjustment to the carrying value of the disposal group.

To estimate the fair value of ourits reporting units, we usethe Company generally uses a combination of the market approach and the income approach. Under the market approach, we estimateit estimates fair value by comparing the business to similar businesses, or guideline companies whose securities are actively traded in public markets. Under the income approach, we useit uses a discounted cash flow (“DCF”) model in which cash flows anticipated over future periods, plus a terminal value at the end of that time horizon, are discounted to their present value using an appropriate expected rate of return. The fair value estimates inthat is commensurate with the goodwill impairment analysis are highly sensitive to the discount rates used in the expected cash flows attributable torisk inherent within the reporting units. The discount rates are the weighted average cost of capital measuring the reporting unit’s cost of debt and equity financing weighted by the percentage of debt and percentage of equity in a company’s target capital.unit. Other estimates inherent in both the market and income approaches include long-term growth rates, projected revenues, and earnings and cash flow forecasts for the reporting units. In addition, we comparethe Company compares the aggregate of the reporting units’ fair valuevalues to the Company’s market capitalization as a further corroboration of the fair values. Goodwill testing requires a complex series of assumptions and judgments by management in projecting future operating results, selecting guideline companies for comparisons and assessing risks. The use of alternative assumptions and estimates could affect the fair values and change the impairment determinations.
Intangible Assets: Currently all of ourthe Company’s intangible assets are subject to amortization and are amortized based on the pattern of their economic consumption or on a straight-line basis over their estimated useful lives, ranging from one to 38 years. We reviewThe Company reviews intangible assets for impairment at an asset group level whenever events or changes in circumstances indicate that the carrying value of the assets may not be recoverable. Determination of recoverability is based on the lowest level of identifiable estimated future undiscounted cash flows resulting from use of the asset and its eventual disposition. Measurement of any impairment loss is based on the excess of the carrying value of the asset group over its estimated fair market value.

It is ourthe Company’s policy to retain a significant portion of certain losses, primarilyincluding those related to workers’ compensation and comprehensive general, product, and vehicle liability. Provisions for losses expected under theseinsurance programs are recorded based on ourthe Company’s estimate of the aggregate liability for claims incurred as well as for claims incurred but not yet reported.

This segment engages in multiple-element arrangements, which may contain any combination of software, hardware, implementation, SaaS-based offerings, consulting services or maintenance services. For multiple-element arrangements that do not include software, revenue is allocated to the separate elements based on their relative selling price and recognized in accordance with the revenue recognition criteria applicable to each element. Relative selling price is determined based on vendor-specific objective evidence (“VSOE”) of selling price if available, third-party evidence (“TPE”), if VSOE of selling price is not available, or estimated selling price (“ESP”) if neither VSOE of selling price nor TPE is available. For multiple-element arrangements accounted for in accordance with specific software accounting guidance when some elements are delivered prior to others in an arrangement and VSOE of fair value exists for the undelivered elements, revenue for the delivered elements is recognized upon delivery of such items. The segment establishes VSOE for hardware and implementation and consulting services based on the price charged when sold separately, and for maintenance services, based on renewal rates offered to customers. Revenue for the software element is recognized under the residual method only when fair value has been established for all of the undelivered elements in an arrangement. If fair value cannot be established for any undelivered element, all of the arrangement’s revenue is deferred until the delivery of the last element or until the fair value of the undelivered element is determinable. For multiple-element arrangements with both software and nonsoftware elements, arrangement consideration is allocated between the software elements as a whole and nonsoftware elements.  The segment then further allocates consideration to the individual elements within the software group, and revenue is recognized for all elements under the applicable accounting guidance and our policies described above.
Supplier Incentives: Fees for services and other incentives received from suppliers, relating to the purchase or distribution of inventory, are considered product discounts and are generally reported as a reduction to cost of sales. We consider these fees and other incentives to represent product discounts and as a result, the amounts are recognized within cost of sales upon the sale of the related inventory.

All of the supplier reserves at March 31, 2018 and 2017primarily pertain to our Distribution Solutionsthe Company’s U.S. Pharmaceutical segment.
Income Taxes: We account The Company accounts for income taxes under the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the financial statements or the tax returns. Under this method, deferred tax assets and liabilities are determined based on the difference between the financial statements and the tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. Tax benefits from uncertain tax positions are recognized when it is more likely than not that the position will be sustained upon examination, including resolutions of any related appeals or litigation processes, based on the technical merits. The amount recognized is measured as the largest amount of tax benefit that is greater than 50 percent likely of being realized upon effective settlement. Deferred taxes are not provided

The Company reviews all contingencies at least quarterly to determine whether the likelihood of loss has changed and to assess whether a reasonable estimate of the loss or a range of the loss can be made. As discussed above, development of a meaningful estimate of loss or a range of potential loss is complex when the outcome is directly dependent on negotiations with or decisions by third parties, such as regulatory agencies, the court system, and other interested parties. Such factors bear directly on whether itRefer to Financial Note 19, “Commitments and Contingent Liabilities,” for additional information related to ongoing controlled substances claims to which the Company is possible to reasonably estimate a range of potential loss and boundaries of a high and low estimate.party.

Underexpense over the amended guidance, we are required to reflect the income tax effects in the enactment period of those aspects of the 2017 Tax Act for which the accounting is complete. We are required to record a provisional estimate in our consolidated financial statements if the accounting for certain aspects of the 2017 Tax Act are incomplete provided that the effects are reasonably determinable. Such provisional amounts are subject to further adjustments during the measurement period until the accounting for the income tax effects is finalized. If the effects of the 2017 Tax Act are not reasonably determinable, we would continue to apply the accounting guidance that was in effect immediately before the 2017 Tax Act’s enactment date until the provisional amounts become reasonably estimable. The SEC staff guidance also requires additional disclosures when the accounting related to the 2017 Tax Act is not complete.

Derivatives and Hedging: In the fourth quarter of 2018, we elected to early adopt amended guidance for derivatives and hedging on a modified retrospective basis. The amended guidance was issued to improve the accounting for hedging activities and to better align an entity’s risk management activities and financial reporting for hedging relationships. The amended guidance, among other provisions, eliminates the existing requirement to recognize periodic hedge ineffectiveness in earnings for cash flow hedges and net investment hedges that are highly effective and requires that all items that affect earnings be classified in the same income statement line as the hedged item.service period. The adoption of this amended guidance did not have a material effectimpact on ourthe Company’s consolidated financial statements.statements or disclosures.
Goodwill Impairment Testing:  In the second quarter of 2018, we elected to adopt amended guidance which simplifies goodwill impairment testing by eliminating the second step of the impairment test. The amended guidance requires an impairment charge to be recognized for the amount by which the carrying amount of a reporting unit exceeds its fair value under a one-step impairment test. Refer to Financial Note 3, “Goodwill Impairment Charges” for more information.
Investments:In the first quarter of 2018, we2021, the Company retrospectively adopted amended guidanceASU 2018-14, Compensation - Retirement Benefits - Defined Benefit Plans, which requires the Company to disclose the weighted-average interest crediting rates for cash balance plans and other plans with promised interest crediting rates, and an explanation of reasons for significant gains and losses related to changes in the benefit obligation for the equity method of accounting.period. The amended guidance simplifiesalso requires the transitionCompany to remove disclosures on the equity method of accounting. This standard eliminates the requirement that when an existing cost method investment qualifies for use of the equity method, an investor must restate its historical financial statements, as if the equity method had been used during all previous periods.

The adoption of this amended guidance resulted in changes in disclosures but did not have an effect on our consolidated financial statements.
Consolidation: In the first quarter of 2018, we adopted amended guidance for VIEs. The amended guidance requires a single decision maker of a VIE to consider indirect economic interests in the entity held through related parties that are under common control on a proportionate basis when determining whether it is the primary beneficiary of that VIE.  This amendment does not change the existing characteristics of a primary beneficiary. The adoption of this amended guidance did not have a material effect on our consolidated financial statements.
Inventories: In the first quarter of 2018, we adopted amended guidance for the subsequent measurement of inventory. The amended guidance requires entities to measure inventory at the lower of cost or net realizable value. Net realizable value is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. The requirement replaced the lower of cost or market evaluation previously applied. Accounting guidance is unchanged for inventory measured using the LIFO or the retail method. The adoption of this amended guidance did not have a material effect on our consolidated financial statements.
Share-Based Payments: In the first quarter of 2017, we adopted amended guidance for employee share-based payment awards.  Under the amended guidance, all excess tax benefits (“windfalls”) and deficiencies (“shortfalls”) related to employee share-based compensation arrangements are recognized within income tax expense. Under the previous guidance, windfalls were recognized in additional paid-in capital (“APIC”) and shortfalls were only recognized to the extent they exceeded the pool of windfall tax benefits. The amended guidance also requires excess tax benefits to be classified as an operating activity in the statement of cash flows, rather than a financing activity. The primary impact of the adoption was the recognition of excess tax benefits in the income statement on a prospective basis, rather than APIC. As a result, discrete tax benefits of $54 million were recognized in income tax expense in 2017. We also elected to adopt the cash flow presentation of the excess tax benefits prospectively commencing in the first quarter of 2017.  None of the other provisions in this amended guidance had a material impact on our consolidated financial statements.
Business Combinations: In the first quarterCompany’s Consolidated Statements of 2017, we adopted amended guidance for an acquirer’s accounting for measurement-period adjustments. The amended guidance eliminates the requirement that an acquirer in a business combination account for measurement-period adjustments retrospectively and instead requires that measurement-period adjustments be recognized during the period in which it determines the adjustment. In addition, the amended guidance requires that the acquirer record, in the same period’s financial statements, the effect on earnings of changes in depreciation, amortization,Operations, Comprehensive Income (Loss), Balance Sheets, or other income effects, if any, as a result of the change to the provisional amounts, calculated as if the accounting had been completed at the acquisition date.

The amended guidance requires debt issuance costs related to a recognized debt liability to be reported on the balance sheet as a direct deduction from the carrying amount of that debt liability.  The recognition and measurement guidance for debt issuance costs are not affected by the amended guidance. In August 2015, a clarification was added to this amended guidance that debt issuance costs related to line-of-credit arrangements can continue to be deferred and presented as an asset on the balance sheet. Upon adoption, unamortized debt issuance costs of $40 million were reclassified primarily from other noncurrent assets to long-term debt at March 31, 2016.trade accounts receivable.

The adoption of this amended guidance did not have a material effect on our consolidated financial statements.
Discontinued Operations: In the first quarter of 2016, we adopted amended guidance for reporting of discontinued operations and disclosures of disposals of components.  The amended guidance revises the criteria for disposals to qualify as discontinued operations and permits significant continuing involvement and continuing cash flows with the discontinued operation.  In addition, the amended guidance requires additional disclosures for discontinued operations and new disclosures for individually material disposal transactions that do not meet the definition of a discontinued operation.

Recently Issued Accounting Pronouncements Not Yet Adopted
Accumulated Other Comprehensive Income:In February 2018, amended guidanceDecember 2019, ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes, was issued with the intent to address a narrow-scope financial reporting issue that arose as a consequencesimplify various aspects related to accounting for income taxes. The guidance eliminates certain exceptions related to the approach for intraperiod tax allocation, the methodology for calculating income taxes in an interim period, and the recognition of the 2017 Tax Act. Existing guidance requires that deferred tax liabilities and assets be adjusted for a change in tax laws with the effect included in income from continuing operations in the reporting period that includes the enactment date. That guidance is applicable even in situations in which the related income tax effects of items in accumulated other comprehensive income were originally recognized in other comprehensive income rather in net income, such as amounts related to benefit plans and hedging activity. As a result, the tax effects of items within accumulated other comprehensive income do not reflect the appropriate tax rate. This difference is referred to as stranded tax effects.outside basis differences. The amended guidance allows for a reclassification of only those amounts related to the 2017 Tax Act to retained earnings thereby eliminating the stranded tax effects. The amended guidance also requiressimplifies and clarifies certain disclosures about stranded tax effects.other aspects of accounting for income taxes. The amended guidance is effective for us beginningthe Company in the first quarter of 2020 on a prospective or retrospective basis. Early2022 and early adoption is permitted. We are currently evaluating the impact of this amended guidance on our consolidated financial statements.
Share-Based Payments: In May 2017, amended guidance was issued for employee share-based payment awards. This amendment provides guidance on which changes to terms or conditions of a share-based payment award require an entity to apply modification accounting. Under the amended guidance, we are required to account for the effects of a modification if the fair value, the vesting conditions or the classification (as an equity instrument or a liability instrument) of the modified award change from that of the original award immediately before the modification. The amended guidance is effective for us commencing in the first quarter of 2019 on a prospective basis.  Early adoption is permitted.  We do not expect the adoption of this amended guidance is not expected to have a material effect on our consolidated financial statements.
Premium Amortization of Purchased Callable Debt Securities: In March 2017, amended guidance was issued to shorten the amortization period for certain callable debt securities held at a premium.  The amended guidance requires the premium of callable debt securities to be amortized to the earliest call date but does not require an accounting change for securities held at a discount as they would still be amortized to maturity.  The amended guidance is effective for us on a modified retrospective basis commencing in the first quarter of 2020.  Early adoption is permitted.  We are currently evaluating the impact of this amended guidance on our consolidated financial statements.
Compensation - Retirement Benefits: In March 2017, amended guidance was issued which requires us to report the service cost component of defined benefit pension plans and other postretirement plans in the same line item as other compensation costs arising from services rendered by the pertinent employees during the period. Other components of net benefit cost are required to be presented in the statements of operations separately from the service cost component outside of operating income. This amended guidance is effective for us in the first quarter of 2019 on a retrospective basis. Early adoption is permitted. We expect the adoption of this amended guidance to have a material effect on our consolidated financial statements. This amended guidance is expected to only result in a change in presentation of other components of net benefit costs on our consolidated statement of operations (a reclassification from operating income to other income, net).
Derecognition of Nonfinancial Assets: In February 2017, amended guidance was issued that defines the term “in substance nonfinancial asset” as a financial asset promised to a counterparty in a contract if substantially all of the fair value of the asset that is promised is concentrated in nonfinancial assets. The scope of this amendment includes nonfinancial assets transferred within a legal entity including a parent entity’s transfer of nonfinancial assets by transferring ownership interests in consolidated subsidiaries. The amendment excludes all businesses and nonprofit activities from its scope and therefore all entities, with limited exceptions, are required to account for the derecognition of a business or nonprofit activity in accordance with the consolidation guidance once this amended guidance becomes effective. We are required to apply this amended guidance at the same time we apply the amended revenue guidance in the first quarter of 2019. It allows for either full retrospective or modified retrospective adoption.  Early adoption is permitted.  We do not expect the adoption of this amended guidance to have a material effect on our consolidated financial statements.

Business Combinations: In January 2017, amended guidance was issued to clarify the definition of a business to assist entities in evaluating whether transactions should be accounted for as acquisitions of assets or businesses. The amended guidance provides a practical screen to determine when an integrated set of assets and activities (collectively referred to as a “set”) is not a business. The screen requires that when substantially all of the fair value of the gross assets acquired is concentrated in a single identifiable asset or a group of similar identifiable assets, the set is not a business. If the screen is not met, the amended guidance requires that to be considered a business, a set must include an input and a substantive process that together significantly contribute to the ability to create output. The amended guidance is effective for us commencing in the first quarter of 2019 on a prospective basis. Early adoption is permitted in certain circumstances.  We do not expect the adoption of this amended guidance to have a material effect on our consolidated financial statements.
Restricted Cash: In November 2016, amended guidance was issued that requires restricted cash and restricted cash equivalents to be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total cash amounts shown on the statement of cash flows. Transfers between cash and cash equivalents and restricted cash or restricted cash equivalents are not reported as cash flow activities in the statement of cash flows.  The amended guidance is effective for us commencing in the first quarter of 2019 on a retrospective basis. Early adoption is permitted. We expect the adoption of this amended guidance to have no effect on our consolidated statements of operations, comprehensive income or our consolidated balance sheets. This amended guidance is expected to only result in a change in presentation of restricted cash and restricted cash equivalents on our consolidated statement of cash flows.
Income Taxes - Intra-Entity Transfers of Assets Other Than Inventory: In October 2016, amended guidance was issued to require entities to recognize income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs. The amended guidance is effective for us commencing in the first quarter of 2019 on a modified retrospective basis. Upon adoption of this amended guidance in the first quarter of 2019, we anticipate recording approximately $130 million to $160 million of deferred tax assets with a corresponding cumulative-effect increase to the beginning balance of retained earnings in ourCompany’s consolidated financial statements for the tax consequences relating to an intra-entity transfer of certain software.or disclosures.

Financial Instruments - Credit Losses: In June 2016, amended guidance was issued, which will change the impairment model for most financial assets and require additional disclosures. The amended guidance requires financial assets that are measured at amortized cost be presented at the net amount expected to be collected. The allowance for credit losses is a valuation account that is deducted from the amortized cost basis of financial assets. The amended guidance also requires us to consider historical experience, current conditions, and reasonable and supportable forecasts that affect the collectibility of the reported amount in estimating credit losses. The amended guidance becomes effective for us commencing in the first quarter of 2021 and will be applied through a cumulative-effect adjustment to the beginning retained earnings in the year of adoption. Early adoption is permitted.  We are currently evaluating the impact of this amended guidance on our consolidated financial statements.
Leases: In February 2016, amended guidance was issued for lease arrangements. The amended guidance will require lessees to recognize assets and liabilities on the balance sheet for all leases with terms longer than 12 months and provide enhanced disclosures on key information of leasing arrangements.  The amended guidance is effective for us commencing in the first quarter of 2020.  Early adoption is permitted.  We plan to adopt the amended guidance on the effective date and expect that the adoption of the amended lease guidance will materially affect our consolidated balance sheet and will require certain changes to our systems and processes.
Financial Instruments: In January 2016, amended guidance was issued that requires equity investments to be measured at fair value with changes in fair value recognized in net income and enhanced disclosures about those investments. This guidance also simplifies the impairment assessments of equity investments without readily determinable fair value. The investments that are accounted for under the equity method of accounting or result in consolidation of the investee are excluded from the scope of this amended guidance. The amended guidance will become effective for us commencing in the first quarter of 2019 and will be applied through a cumulative-effect adjustment. Early adoption is not permitted except for certain provisions.  We do not expect the adoption of this amended guidance to have a material effect on our consolidated financial statements.

Revenue Recognition: In May 2014, amended guidance was issued for recognizing revenue from contracts with customers. Under the amended guidance, revenues will be recognized when an entity satisfies a performance obligation by transferring control of a promised good or service to a customer in an amount that reflects the consideration to which the entity expects to be entitled for that good or service. The amended guidance also requires additional quantitative and qualitative disclosures. Additional amendments were also issued subsequently, including clarifications on principal versus agent considerations, performance obligations, and certain scope improvements and practical expedients.  The amended guidance is effective for us commencing in the first quarter of 2019. We will adopt this amended guidance on a modified retrospective basis in our first quarter of 2019. Our equity method investee, Change Healthcare will adopt the amended guidance in our first quarter of 2020. Change Healthcare is currently evaluating the adoption impact.Joint Venture

We continue to make progress on our evaluation of the adoption impact including a review of the amended guidance as compared to our current accounting policies and customer contract reviews.  We substantially completed our assessment duringIn the fourth quarter of 2018. Our revenue is primarily generated from sales of pharmaceutical products, which will continue to be recognized when goods are transferred to2017, the customer. We have substantially similar performance obligations under the amended guidance as compared with deliverables and units of account currently being recognized. Accordingly, we generally anticipate that the timing of recognition of distribution revenue will be substantially unchanged under the amended guidance. Upon adoption of this amended guidance, we expect to recognize an immaterial adjustment to retained earnings reflecting the cumulative impact for estimated variable consideration, subject to the constraint.
2.Healthcare Technology Net Asset Exchange
On March 1, 2017, weCompany contributed the majority of ourits McKesson Technology Solutions businesses (“Core MTS Business”) to the newly formedform a joint venture, the Change Healthcare JV, under the terms of a contribution agreement previously entered into between McKesson and Change Healthcare Holdings, Inc. (“Change”) and others, including shareholders of Change. We retained our RelayHealth Pharmacy (“RHP”) and Enterprise Information Solutions (“EIS”) businesses. The EIS business was subsequently sold to a third party in the third quarter of 2018. In exchange for the contribution, we ownthe Company initially owned approximately 70% of the joint venture, with the remaining equity ownership of approximately 30% held by shareholders of Change. The joint venture isChange Healthcare JV was jointly governed by usMcKesson and shareholders of Change.
Gain from Healthcare TechnologyNet Asset Exchange
We accounted for this transaction asOn June 27, 2019, common stock and certain other securities of Change began trading on the NASDAQ (“IPO”). Change was a sale of the Core MTS Businessholding company and a subsequent purchase of a 70%did not own any material assets or have any operations other than its interest in the newly formed joint venture.Change Healthcare JV. On July 1, 2019, upon the completion of its IPO, Change received net cash proceeds of approximately $888 million. Change contributed the proceeds of $609 million from its offering of common stock to the Change Healthcare JV in exchange for additional membership interests of the Change Healthcare JV (“LLC Units”) at the equivalent of its offering price of $13 per share. The proceeds of $279 million from the concurrent offering of other securities were used by Change to acquire certain securities of the Change Healthcare JV that substantially mirrored the terms of other securities included in the offering by Change. As a result, McKesson’s equity interest in the Change Healthcare JV was diluted from approximately 70% to approximately 58.5% while Change owned approximately 41.5% of the outstanding LLC Units. Accordingly, in the second quarter of 2020, the Company recognized a dilution loss of $246 million, primarily representing the difference between its proportionate share of the IPO proceeds and the dilution effect on the investment’s carrying value. The Company’s proportionate share of income or loss from this investment was subsequently reduced as immaterial settlements of stock option exercises occurred after the IPO. These amounts were included in “Equity earnings and charges from investment in Change Healthcare Joint Venture” in the Company’s Consolidated Statements of Operations for the year ended March 31, 2020.
In the second quarter of 2020, the Company recorded an other-than-temporary impairment (“OTTI”) charge of $1.2 billion to its investment in the Change Healthcare JV, representing the difference between the carrying value of the Company’s investment and the fair value derived from the corresponding closing price of Change’s common stock at September 30, 2019. This charge was included in “Equity earnings and charges from investment in Change Healthcare Joint Venture” in the Company’s Consolidated Statements of Operations for the year ended March 31, 2020.

Separation of the Change Healthcare JV
On March 10, 2020, the Company completed the previously announced separation of its interest in the Change Healthcare JV. The separation was affected through the split-off of PF2 SpinCo, Inc. (“SpinCo”), a wholly-owned subsidiary of the Company that held all of the Company’s interest in the Change Healthcare JV, to certain of the Company’s stockholders through an exchange offer (“Split-off”), followed by the merger of SpinCo with and into Change, with Change surviving the merger (“Merger”).
In connection with the Split-off, on March 9, 2020, the Company distributed all 176.0 million outstanding shares of common stock of SpinCo to participating holders of the Company’s common stock in exchange for 15.4 million shares of McKesson common stock which now are held as treasury stock on the Company’s Consolidated Balance Sheets. Refer to Financial Note 20, “Stockholders' Equity,” for more information. Following consummation of the exchange offer, on March 10, 2020, SpinCo was merged with and into Change Healthcare, and each share of SpinCo common stock converted into 1 share of Change common stock, par value $0.001 per share, with cash being paid in lieu of fractional shares of Change common stock. The Split-off and the Merger are intended to be generally tax-free transactions for U.S. federal income tax purposes. Following the Split-off, the Company does not beneficially own any of Change’s outstanding securities.

Related Party Transactions
In connection with the transaction,formation of the Change Healthcare JV, McKesson, the Change Healthcare JV and certain shareholders of Change entered into various ancillary agreements, including transition services agreements (“TSA”), a transaction and advisory fee agreement (“Advisory Agreement”), a tax receivable agreement (“TRA”) and certain other commercial agreements.
Pursuant to Fees incurred or earned from the TRA, McKesson may be required to make certain paymentsAdvisory Agreement were not material for 2020 and 2019. Fees incurred or may be entitled to receive certain payments related toearned from the cash tax savings attributable to the utilization of certain tax attributes, including certain amortizable tax basis in software contributed by McKesson to Change Healthcare. No such payments were required to be made or received for 2017 and 2018. At March 31, 2018 and 2017, we had $90 million and $136 million of noncurrent liability payable to shareholders of Change associated with the TRA. During 2018, we recorded a credit of $46 million in operating expense to reduce this liability to $90 million reflecting a reduction in future applicable tax rate related to the 2017 Tax Act. The TRA liability remained at $90 million at March 31, 2018. The amount of liability is determined based on certain estimates and could become payable in periods after a disposition of our investment in Change Healthcare.
The total fees charged by us to the joint venture for various transition services under the TSA were $91 million in 2018 and were not material in 2017. Transition services fees are included within operating expenses2021 and were $22 million in our consolidated statements of operations.

Revenues recognized and expenses incurred under commercial arrangements with Change Healthcare were not material during 2018 and 2017.

At March 31, 2018 and 2017, receivables due from the joint venture were not material.
3.Goodwill Impairment Charges
We recorded non-cash pre-tax goodwill impairment charges of $1,738 million within the Distribution Solutions segmentAgreement was terminated in 2018 and $290 million within the Technology Solutions segment in 2017. The charges were recorded under the caption, “Goodwill Impairment Charges” in the accompanying consolidated statements of operations.

Goodwill impairment testing is conducted at the reporting unit level, which is generally defined as an operating segment or one level below an operating segment (also known as a component), for which discrete financial information is available and segment management regularly reviews the operating results of that reporting unit. We evaluate goodwill for impairment on an annual basis as of January 1 each year and at an interim date, if indicators of potential impairment exist.

The fair value of the reporting unit was determined using a combination of an income approach based on a DCF model and a market approach based on guideline public companies’ revenues and earnings before interest, tax, depreciation and amortization multiples. Fair value estimates result from a complex series of judgments about future events and uncertainties and rely heavily on estimates and assumptions that have been deemed reasonable by management as of the measurement date. Any changes in key assumptions, including failure to improve operations of certain retail pharmacy stores, additional government reimbursement reductions, deterioration in the financial market, an increase in interest rates or an increase in the cost of equity financing by market participants within the industry, or other unanticipated events and circumstances, may affect such estimates. Fair value assessments of the reporting unit are considered a Level 3 measurement due to the significance of unobservable inputs developed using company
specific information.

Fiscal 2018

McKesson Europe

In 2018, we recorded total non-cash pre-tax and after-tax charges of $1,283 million to impair the carrying value of goodwill for our McKesson Europe reporting unit within our Distribution Solutions segment, as further described below.

McKESSON CORPORATION
FINANCIAL NOTES (Continued)

In 2019, the Company renegotiated the terms of the TRA which resulted in the extinguishment and derecognition of the $90 million non-current liability payable to the shareholders of Change. In exchange for the shareholders of Change agreeing to extinguish the liability, the Company agreed to an allocation of certain tax amortization that had the effect of reducing the amount of a distribution from the Change Healthcare JV that would otherwise have been required to be made to the shareholders of Change. As a result of the renegotiation, McKesson was relieved from any potential future obligations associated with the non-current liability and recognized a credit of $90 million in “Selling, distribution, general, and administrative expenses” in its Consolidated Statement of Operations in 2019. At March 31, 2021 and 2020, the Company had 0 outstanding payable balance to the shareholders of Change under the TRA.
Under the agreement executed in 2019 between the Change Healthcare JV, McKesson, Change, and certain subsidiaries of the Change Healthcare JV, McKesson had the ability to adjust the manner in which certain depreciation or amortization deductions are allocated among Change and McKesson. McKesson exercised its right under the agreement and allocated certain depreciation and amortization deductions to Change for the tax years ended March 31, 2020 and 2019.
After McKesson’s separation of its interest in the Change Healthcare JV, the aforementioned TRA agreement requires the Change Healthcare JV to pay McKesson 85% of the net cash tax savings realized, or deemed to be realized, by Change resulting from the depreciation or amortization allocated to Change by McKesson. The receipt of any payments from the Change Healthcare JV under the TRA is dependent upon Change benefiting from this depreciation or amortization in future tax return filings. This creates uncertainty over the amount, timing, and probability of the gain recognized. As such, the Company accounts for the TRA as a gain contingency, with 0 receivable recognized as of March 31, 2021 or 2020.
In conjunction with the separation transaction in the fourth quarter of 2020, the Company recorded a reversal of the deferred tax liability related to its investment. Under the agreement with the Change Healthcare JV, McKesson, Change, and certain subsidiaries of the Change Healthcare JV, there may be changes in future periods to the amount reversed as the relevant periods are audited by tax authorities. Any such change is not expected to have a material impact on the Company’s consolidated financial statements.
3.    Held for Sale
Assets and liabilities that have met the classification as held for sale were $12 million and $9 million, respectively, as of March 31, 2021 and $906 million and $683 million, respectively, as of March 31, 2020. The amounts at March 31, 2020 primarily consisted of the majority of the Company’s German pharmaceutical wholesale business as described below. This disposal group had been recorded as assets and liabilities held for sale since the third quarter of 2020 through its contribution to a joint venture in the third quarter of 2021. Based on its analysis, the Company determined that the disposal groups classified as held for sale do not meet the criteria for classification as discontinued operations and are not considered to be significant disposals based on its quantitative and qualitative evaluation.
German Wholesale Joint Venture
On November 1, 2020, the Company completed its previously announced transaction with Walgreens Boots Alliance (“WBA”) whereby the majority of its German pharmaceutical wholesale business was contributed to a newly formed joint venture in which McKesson has a 30% noncontrolling interest.
Consideration received included a receivable amount of $41 million, primarily related to working capital and net debt adjustments from WBA, and the 30% interest in the newly formed joint venture. At the transaction date, the carrying value of the equity investment in the joint venture was recorded at its fair value, which was measured using inputs that fell within Level 3 of the fair value hierarchy. The carrying value of the investment in the joint venture was NaN as of March 31, 2021. The Company accounts for its interest in the joint venture as an equity method investment within the International segment. The joint venture also assumed a note payable to the Company in the amount of approximately $291 million as of the transaction date, which was paid to the Company in the third quarter of 2021.

In conjunction with the contribution, the Company recorded losses of $58 million and $275 million (pre-tax and after-tax), respectively, in the years ended March 31, 2021 and 2020, which includes adjustments to remeasure the assets and liabilities held for sale to fair value less costs to sell. These charges were included within “Operating expenses” in the Consolidated Statements of Operations. The Company’s measurement of the fair value of the disposal group was based on estimates of total consideration to be received by the Company as outlined in the contribution agreement between the Company and WBA. As a result of finalization of working capital amounts contributed and other adjustments, the Company may record additional gains or losses in future periods; however, these adjustments are not expected to have a material impact on the Company’s consolidated financial statements.
Following the completion of the transaction on November 1, 2020, there were 0 assets or liabilities of the German pharmaceutical wholesale joint venture classified as held for sale on the Company’s Consolidated Balance Sheet.

In addition, charges related to restructuring initiatives are included in “Cost of sales” in the Consolidated Statements of Operations and were not material for the years ended 2021, 2020, and 2019.
Restructuring Initiatives
During the first quarter of 2022, the Company approved an initiative to increase operational efficiencies and flexibility by transitioning to a partial remote work model for certain employees. This initiative primarily includes the rationalization of its office space in North America. Where the Company determines to cease using office space, it plans to exit the portion of the facility no longer used. It also may retain and repurpose certain other office locations. The Company expects to incur total charges of approximately $180 million to $280 million for this initiative, consisting primarily of exit related costs, accelerated depreciation and amortization of long-lived assets, and asset impairments. This initiative is expected to be completed in 2022.

Long-Lived Asset Impairments
Fiscal 2021
In 2021, the Company recognized charges of $115 million to impair certain long-lived assets within the Company’s International segment. These charges primarily related to long-lived assets associated with the Company’s retail pharmacy businesses in Canada and Europe reporting unit had a declineand were due to declines in its estimated future cash flows primarily in our United Kingdom (“U.K.”) retail business,partially driven by significant government reimbursement reductions affecting retail pharmacy economics acrossa revised outlook regarding the U.K. market. Accordingly, we performedimpacts of COVID-19. The Company used both an interim one-step goodwill impairment test underincome approach (a DCF method) and a market approach to estimate the amended goodwill guidance for this reporting unit prior to our annual impairment test. As a result of the interim impairment test, the estimated fair value of this reporting unit was determinedthe long-lived assets.
Fiscal 2020

Stock Plans
In July 2013, ourthe Company’s stockholders approved the 2013 Stock Plan to replace the 2005 Stock Plan. TheseUnder these stock plans, provide ourthe Company may issue restricted stock, RSUs, PSUs, PeRSUs, stock options, and other share-based awards to selected employees, officers, and non-employee directors the opportunity to receive equity-based, long-term incentives in the form of stock options, restricted stock, RSUs, PeRSUs, TSRUs and other share-based awards.directors. The 2013 Stock Plan reserves 30 million shares plus the remaining number ofunused reserved shares reserved but unused under the 2005 Stock Plan. As of March 31, 2018, 282021, 20 million shares remain available for future grant under the 2013 Stock Plan.
Stock Options
Stock options are granted with an exercise price at no less than the fair market value and those options granted under the stock plans generally have a contractual term of seven years and follow a four year vesting schedule.
Compensation expense for stock options is recognized on a straight-line basis over the requisite service period and is based on the grant-date fair value for the portion of the awards that is ultimately expected to vest. We use the Black-Scholes options-pricing model to estimate the fair value of our stock options. Once the fair value of an employee stock option is determined, current accounting practices do not permit it to be changed, even if the estimates used are different from actual. The options-pricing model requires the use of various estimates and assumptions as follows:
Expected stock price volatility is based on a combination of historical volatility of our common stock and implied market volatility. We believe that this market-based input provides a reasonable estimate of our future stock price movements and is consistent with employee stock option valuation considerations.
Expected dividend yield is based on historical experience and investors’ current expectations.
The risk-free interest rate for periods within the expected life of the option is based on the constant maturity U.S. Treasury rate in effect at the time of grant.
Expected life of the options is based primarily on historical employee stock option exercises and other behavior data and reflects the impact of changes in contractual life of current option grants compared to our historical grants.

Restricted Stock Unit Awards
RSUs which entitle the holder to receive at the end of a vesting term a specified number of shares of the Company’s common stock are accounted for at fair value at the datewhich vest over a period of grant. Total compensation expense for RSUs under our stock plans isgenerally three to four years as determined by the productCompensation Committee at the time of grant. The fair value of the number of shares that are expected to vest andaward is determined based on the grant date market price of the Company’s common stock. The Compensation Committee determinesstock on the grant date and the related compensation expense is recognized over the vesting terms at the time of grant. These awards generally vest in three to four years. We recognize compensation expense for RSUsperiod on a straight-line basis over the requisite service period.basis.
Non-employee directors receive an annual grant of RSUs, which vest immediately and are expensed upon grant. The director may elect to receive the underlying shares immediately or defer receipt of the shares if they meet director stock ownership guidelines. The shares will be automatically deferred for those directors who do not meet the director stock ownership guidelines. At March 31, 2018,2021, approximately 117,00082,000 RSUs for ourthe Company’s directors are vested.
PSUs are conditional upon the attainment of market and performance objectives over a specified period. The number of vested PSUs is assessed at the end of a three-year performance period upon attainment of meeting certain earnings per share targets, average return on invested capital, and for certain participants, total shareholder return relative to a peer group of companies and, for special PSUs granted in 2019, meeting certain cumulative operating profit metrics. The Company uses the Monte Carlo simulation model to measure the fair value of the total shareholder return portion of the PSUs. The earnings per share portion of the PSUs is measured at the grant date market price. PSUs have a requisite service period of generally three years. Expense is attributed to the requisite service period on a straight-line basis based on the fair value of the PSUs, adjusted for the performance modifier at the end of each reporting period. For PSUs that are designated as equity awards, the fair value is measured at the grant date. For PSUs that are eligible for cash settlement and designated as liability awards, the Company re-measures the fair value at the end of each reporting period and adjusts a corresponding liability in its Consolidated Balance Sheets for changes in fair value.

PeRSUs arenow classified and accounted for as variable awards untilRSUs. The Company did 0t grant any PeRSUs during the performance goals are reached at which time the grant date is established. Total compensation expense for PeRSUs is determined by the product of the number of shares eligible to be awardedyears ended March 31, 2021 and expected to vest, and the market price of the Company’s common stock, commencing at the inception of the requisite service period. During the performance period, the compensation expense for PeRSUs is re-computed using the market price and the performance modifier at the end of a reporting period. At the end of the performance period, if the goals are attained, the awards are granted and classified as RSUs and accounted for on that basis. We recognize compensation expense for these awards on a straight-line basis over the requisite aggregate service period of generally four years.
TSRUs replaced PeRSUs for our executive officers beginning in 2015. The number of vested TSRUs is assessed at the end of a three-year performance period and is conditioned upon attainment of a total shareholder return metric relative to a peer group of companies. We use the Monte Carlo simulation model to measure the fair value of TSRUs. TSRUs have a requisite service period of approximately three years. Expense is attributed to the requisite service period on a straight-line basis based on the fair value of the TSRUs.  For TSRUs that are designated as equity awards, the fair value is measured at the grant date.  For TSRUs that are eligible for cash settlement and designated as liability awards, we remeasure the fair value at the end of each reporting period and also adjust a corresponding liability on our balance sheet for changes in fair value.2020.

FINANCIAL NOTES (Continued)

In 2018, as a result of the 2017 Tax Act, we recognized a provisional tax benefit of $1,324 million due to the re-measurement of certain deferred taxes to the lower U.S. federal tax rate and a provisional tax expense of $457 million for the one-time tax imposed on certain accumulated earnings and profits (“E&P”) of our foreign subsidiaries.
Our reported income tax benefit rate for 2018 was unfavorably impacted by non-cash pre-tax charges of $1,738 million to impair the carrying value of goodwill related to our McKesson Europe and Rexall Health reporting units within our Distribution Solutions segment, given that no tax benefit was recognized for these charges. Our reported income tax expense rate for 2017 was unfavorably impacted by the non-cash pre-tax charge of $290 million to impair the carrying value of goodwill related to our EIS business within our Technology Solutions segment, given that the majority of this charge was not deductible for income tax purposes. (1)Refer to Financial Note 3, “Goodwill Impairment Charges,2, “Investment in Change Healthcare Joint Venture,” for more information.additional information regarding the separation of the Change Healthcare JV.
On December(2)The Company’s effective tax rates were impacted by other favorable U.S. federal permanent differences including research and development credits of $5 million in 2021 and $7 million in each of 2020 and 2019.
The Company’s reported income tax rate for 2021 was impacted by the charge for pending and future opioid-related claims of $8.1 billion ($6.8 billion after-tax), as described further in Financial Note 19, 2016, we“Commitments and Contingent Liabilities.” The Company recorded a deferred tax benefit of $1.3 billion, which is net of certain non-deductible expenses and an unrecognized tax benefit of $455 million.
During 2021 and 2019, the Company sold various software relating to our Technology Solutions businessintellectual property between wholly ownedwholly-owned legal entities within the McKesson group that are based in different tax jurisdictions. TheIn both instances, the transferor entity recognized a gain on the sale of assets thatwhich was not subject to income tax in its local jurisdiction; such gain wasgains were eliminated upon consolidation. A McKesson entity based in the U.S. was the recipientThe acquiring entities of the software and isintellectual property were entitled to amortize the fair valuepurchase price of the assets for book and tax purposes. TheIn accordance with ASU 2016-16, “Intra-Entity Transfers of Assets Other Than Inventory,” discrete tax benefit associated with the amortizationbenefits of these assets is being recognized over the tax lives of the assets. As a result, we recognized a net tax benefit of $178$105 million and $137$42 million in 2018were recognized for 2021 and 2017.2019, respectively, with a corresponding increase to a deferred tax assets for the temporary difference arising from the buyer’s excess tax basis.
On March 1, 2017, we contributed assets to10, 2020, the Company completed the previously announced separation of its interest in the Change Healthcare JV as described in Financial Note 2, “Healthcare Technology Net Asset Exchange”. While“Investment in Change Healthcare Joint Venture.” The Company’s reported income tax expense rate for 2020 was favorably impacted by this transaction given that it was predominantly structured asintended to generally be a tax free asset contributiontax-free split-off for U.S. federal income tax purposes under Section 721(a) ofpurposes. In the Internal Revenue Code, we recorded tax expense of $929 million on the gain. The tax expense was primarily driven by the recognition of a deferred tax liability on the excess book over tax basis in our equity investment in Change Healthcare.
In March 2016, amended guidance was issued for employee share-based payment awards. Under the amended guidance, all windfalls and shortfalls related to employee share-based compensation arrangements are recognized within income tax expense. We elected to early adopt this amended guidance in the firstfourth quarter of 2017. The primary impact of2020, the adoption was the recognition of excess tax benefits in the income statement on a prospective basis, rather than APIC. As a result, weCompany recognized a net tax benefitgain for financial reporting purposes of $8$414 million and $54 million in 2018 and 2017.
In 2016, we recognized a $19 million tax benefit due to a reduction in our deferred tax liabilities as a result of enacted tax law changes in certain foreign jurisdictions and a $25 million tax benefit associated with the U.S. Tax Court’s decision in Altera Corp. v. Commissioner related to the treatmentseparation transaction.
The Company’s reported income tax expense rate for 2020 was unfavorably impacted by non-cash charges of share-based compensation$275 million to remeasure the carrying value of assets and liabilities held for sale related to the formation of a new German wholesale joint venture within the Company’s International segment. Refer to Financial Note 3, “Held for Sale,” for more information on this transaction which closed in the third quarter of 2021.
The Company’s reported income tax expense in an intercompany cost-sharing agreement.rate for 2019 was unfavorably impacted by non-cash charges of $1.8 billion to impair the carrying value of goodwill for its International segment, given that these charges are generally not deductible for tax purposes.

As of March 31, 2018, we2021, the Company had $1,183 million$1.8 billion of unrecognized tax benefits, of which $1,042 million$1.3 billion would reduce income tax expense and the effective tax rate, if recognized. The increase in unrecognized tax benefits in 20182021 compared to 20172020 is primarily attributable to provisional amounts relatinguncertainty in connection with the deductibility of Opioid-related litigation and claims. Because many uncertainties associated with any potential settlement arrangements or other resolutions of opioid claims including provisions related to deductibility have not been finalized, the application of certain provisionsactual amount of the 2017 Tax Act, partially offset by atax benefit related to uncertain tax positions may differ from these estimates. Refer to Financial Note 19, “Commitments and Contingent Liabilities,” for more information. The decrease in unrecognized tax benefit duebenefits in 2020 compared to 2019 is primarily attributable to the favorable resolution of the Internal Revenue Services (“IRS”) relating to the fiscal years 2010 through 2012. an outstanding California tax refund claim which decreased unrecognized tax benefits by $91 million.
During the next twelve months, we do not expect any material reduction in ourit is reasonably possible that the Company’s unrecognized tax benefits.benefit may decrease by as much as $93 million due to settlements of tax examinations and statute of limitations expirations in the U.S. federal and state jurisdictions and in foreign jurisdictions. However, this amount may change as we continuethe Company continues to have ongoing negotiations with various taxing authorities throughout the year.
We reportThe Company reports interest and penalties on income taxes as income tax expense. WeIt recognized income tax benefits of $1 million and $6 million in 2018 and 2017 and income tax expense of $12$9 million, $23 million, and $33 million in 2016, related to2021, 2020, and 2019, respectively, representing interest and penalties, in our consolidated statementsits Consolidated Statements of operations. The income tax benefit for interest and penalties recognized in 2018 and 2017 was primarily due to concluding certain tax authority examinations and lapses of statutes of limitations.Operations. As of March 31, 20182021 and 2017, we had2020, it accrued $37$101 million and $45$91 million cumulatively in interest and penalties on unrecognized tax benefits.
We fileThe Company files income tax returns in the U.S. federal jurisdiction, various U.S. state jurisdictions, and various foreign jurisdictions. DuringThe Internal Revenue Service (“IRS”) is currently examining the third quarter ofCompany’s U.S. corporation income tax returns for 2018 we signed the Revenue Agent’s Report from the U.S. IRS relating to their audit of the fiscal years 2010 through 2012 and recorded a $39 million tax benefit due to the favorable resolution of various uncertain tax positions for those years. During the first quarter of 2017, we reached an agreement with the IRS to settle all outstanding issues relating to the fiscal years 2007 through 2009 without a material impact to our provision for income taxes. We are subject to audit by the IRS for fiscal years 2013 through the current fiscal year. We are2019. The Company is generally subject to audit by taxing authorities in various U.S. states and in foreign jurisdictions for fiscal years 20102013 through the current fiscal year.
On December 22, 2017, the U.S. government enacted comprehensive new tax legislation under the Tax Cuts and Jobs Act. The 2017 Tax Act makes broad and complex changes to the U.S. tax code that affect our fiscal year 2018 in multiple ways, including but not limited to, (1) reducing the U.S. federal corporate tax rate from 35 percent to 21 percent; and (2) requiring companies to pay a one-time tax on certain unrepatriatedUndistributed earnings of the Company’s foreign subsidiaries.
The 2017 Tax Act also establishes new tax provisions that will affect our fiscal year 2019, including, but not limited to, (1) eliminating the corporate alternative minimum tax; (2) creating the base erosion anti-abuse tax (“BEAT”); (3) establishing new limitations on deductible interest expense and certain executive compensation; (4) creating a new provision designed to tax global intangible low-tax income (“GILTI”); (5) generally eliminating U.S. federal income taxes on dividends from foreign subsidiaries; and (6) changing rules related to uses and limitationsoperations of net operating loss carryforwards created in tax years beginning after December 31, 2017.
On December 22, 2017, the SEC staff issued guidance on income tax accounting for the 2017 Tax Act, which was further incorporated into the U.S. GAAP guidance on income taxes in the fourth quarter of 2018. Refer to Financial Note 1, “Significant Accounting Policies - Recently Adopted Accounting Pronouncements.”
Regarding the new GILTI tax rules, which apply to fiscal years beginning after December 31, 2017, we are allowed to make an accounting policy election to either (1) treat taxes due on future GILTI inclusions in U.S. taxable income as a current-period expense when incurred or (2) reflect such portion of the future GILTI inclusions in U.S. taxable income that relate to existing basis differences in the company’s current measurement of deferred taxes. Our analysis of the new GILTI rules and how they may impact us is incomplete. Accordingly, we have not made a policy election regarding the treatment of the GILTI tax. We will finalize our evaluation of the GILTI tax rules during the measurement period.
Although our accounting for the impactapproximately $6.0 billion were considered indefinitely reinvested. Following enactment of the 2017 Tax Act, the repatriation of cash to the U.S. is incomplete, we have made reasonable estimates and recorded provisional amounts as follows:

Reductiongenerally no longer taxable for federal income tax purposes. However, the repatriation of cash held outside the U.S. federal corporate tax rate: The 2017 Tax Act reduces the corporate tax rate from 35 percent to 21 percent, effective January 1, 2018. U.S. tax law stipulates that our fiscal year 2018 iscould be subject to a blended tax rate of 31.6 percent, which is based on the pro rata number of days in the fiscal year before and after the effective date. For the fiscal year 2019, the tax rate will be 21 percent. As a result, we have remeasured certain deferred tax assets and deferred tax liabilities and recorded a provisional net tax benefit of $1,324 million, mainly driven by a decrease in our deferred tax liabilities for inventories and investments. During the fourth quarter of 2018, this provisional tax benefit increased by $68 million mainly due to changes to the state effect of adjustments made to federal temporary differences. While we were able to make a reasonable estimate of the impact of the reduction in the corporate tax rate, it may be affected by, among other items, changes to estimates the Company has made to calculate our existing temporary differences.

Deemed Repatriation Transition Tax (“Transition Tax”): The 2017 Tax Act imposes a tax on certain accumulated E&P of our foreign subsidiaries. We were able to make a reasonable estimate of the impact of the new tax and recorded a provisional tax expense of $457 million. During the fourth quarter of 2018, this provisional tax expense increased by $23 million mainly due to changes in estimated amounts of post-1986 E&P of the relevant subsidiaries as well as the amount of non-U.S. income taxes paid on such earnings. This estimate may change as we gather additional information to more precisely compute the amount of tax.

Prior to the 2017 Tax Act, undistributed earnings of our foreign operations totaling $5,854 million were considered indefinitely reinvested. While the Company has accrued the 2017 Tax Act’s new tax on these earnings, we were unable to determine a reasonable estimate of the remaining tax liability, if any, for its remaining outside basis differences or assess how the 2017 Tax Act will impact the Company's existing assertion of indefinite reinvestment. As such, no change has been made with respect to this assertion for the year ended March 31, 2018. The Company will complete its analysis of the impact of the 2017 Tax Act on our indefinite reinvestment assertion and record amounts, such asapplicable foreign withholding taxes and state income taxes, if necessary, duringtaxes. The Company may remit foreign earnings to the measurement period.U.S. to the extent it is tax efficient to do so.

OurThe Company’s redeemable noncontrolling interests primarily relate to ourits consolidated subsidiary, McKesson Europe.
Under the December 2014 domination and profit and loss transfer agreement (the “Domination Agreement”), the noncontrolling shareholders of McKesson Europe are entitled to receive an annual recurring compensation amount of €0.83 per share and a one-time guaranteed dividend for calendar year 2014 of €0.83 per share reduced accordingly for any dividend paid by McKesson Europe in relation to that year.share. As a result, during 2018, 20172021, 2020, and 2016, we2019, the Company recorded a total attribution of net income to the noncontrolling shareholders of McKesson Europe of $43 million, $44$42 million, and $44 million.$45 million, respectively.

Under the Domination Agreement, the noncontrolling shareholders of McKesson Europe have a right to put (“Put Right”) their noncontrolling shares at €22.99 per share, increased annually for interest in the amount of 5 percentage points above a base rate published by the German Bundesbank semi-annually, less any compensation amount or guaranteed dividend already paid by McKesson with respect to the relevant time period (“Put Amount”). The exercise of the Put Right will reduce the balance of redeemable noncontrolling interests. During 2018, we2021, the Company paid $50$49 million to purchase 1.91.8 million shares of McKesson Europe through the exercises of the Put Right by the noncontrolling shareholders, whichshareholders. This decreased the carrying value of redeemablethe noncontrolling interests by $53 million.$49 million, and the associated effect of the increase in the Company’s ownership interest on its equity of $3 million was recorded as a net increase to McKesson’s stockholders paid-in capital. During 2020 and 2019, there were no material exercises of the Put Right. The balance of redeemablethe associated liability for Redeemable noncontrolling interests is reported as the greater of its carrying value or its maximum redemption value at each reporting date. The redemption value is the Put Amount adjusted for exchange rate fluctuations each period. The Redeemable noncontrolling interest is also adjusted each period for the proportion of other comprehensive income, primarily due to changes in foreign currency exchange rates, attributable to the noncontrolling shareholders. At March 31, 20182021 and 2017,2020, the carrying value of redeemable noncontrolling interests of $1.46$1.3 billion and $1.33$1.4 billion, respectively, exceeded the maximum redemption value of $1.35$1.2 billion and $1.21 billion.$1.2 billion, respectively. At March 31, 20182021 and 2017, we2020, the Company owned approximately 77%78% and 76%77%, respectively, of McKesson Europe’s outstanding common shares.
Appraisal Proceedings
Subsequent to the Domination Agreement’s registration, certain noncontrolling shareholders of McKesson Europe initiated appraisal proceedings (“Appraisal Proceedings”) with the Stuttgart Regional Court (the “Court”) to challenge the adequacy of the Put Amount, annual recurring compensation amount, and/or the guaranteed dividend. During the pendency of the Appraisal proceedings,Proceedings, such amount will bewas paid as specified currently in the Domination Agreement. If any such Appraisal Proceedings result in an adjustment, we would be required to make certain additional payments for any shortfall to all McKesson Europe noncontrolling shareholders who previously receivedOn September 19, 2018, the Court ruled that the Put Amount shall be increased by €0.51 resulting in an adjusted Put Amount of €23.50.

11.    Leases
In the first quarter of 2020, the Company adopted amended guidance for leases using the modified retrospective method. Upon adoption of this amended guidance, the Company recorded $2.2 billion of operating lease liabilities, $2.1 billion of operating lease ROU assets, and Equipment,a cumulative-effect adjustment of $69 million to opening retained earnings as of April 1, 2019. The adjustment to opening retained earnings included impairment charges of $89 million, net of tax, to the ROU assets primarily related to previously impaired long-lived assets at the retail pharmacies in the Company’s U.K. and Canadian businesses, partially offset by derecognition of existing deferred gain on the Company’s sale-leaseback transaction related to its former corporate headquarters building. The Company also elected to adopt the transition package of practical expedients provided within the amended guidance which eliminated the requirements to reassess lease identification, lease classification, and initial direct costs for leases which commenced before April 1, 2019. The adoption of this guidance did not have a material impact on the Company’s consolidated statements of operations and cash flows.

Lessee
The Company leases facilities and equipment, primarily under operating leases. The Company recognizes lease expense on a straight-line basis over the term of the lease, taking into account, when applicable, lessor incentives for tenant improvements, periods where no rent payment is required, and escalations in rent payments over the term of the lease. As a practical expedient, the Company does not separate lease components from non-lease components such as common area maintenance, utilities, and repairs and maintenance. Remaining terms for facility leases generally range from one to 15 years, while remaining terms for equipment leases generally range from one to five years. Most real property leases contain renewal options (typically for five-year increments). Generally, the renewal option periods are not included within the lease term as the Company is not reasonably certain to exercise that right at lease commencement. The Company’s lease agreements do not contain any material residual value guarantees or material restrictive covenants.
Operating right-of-use (“ROU”) assets and operating lease liabilities are recognized at the lease commencement date. ROU assets represent the Company’s right to use an underlying asset for the lease term and operating lease liabilities represent its obligation to make lease payments arising from the lease. Operating lease liabilities are recognized based on the present value of the future lease payments over the lease term, discounted at the Company’s incremental borrowing rate as the implicit rate in the lease is not readily determinable for most of the Company’s leases. The Company estimates the discount rate as its incremental borrowing rate based on qualitative factors including Company specific credit rating, lease term, general economics, and the interest rate environment. For existing leases that commenced prior to the adoption of the amended leasing guidance, the Company determined the discount rate on April 1, 2019 using the full lease term. Operating lease liabilities are recorded in “Current portion of operating lease liabilities” and “Long-term operating lease liabilities,” and the corresponding lease assets are recorded in “Operating lease right-of-use assets” in the Company’s Consolidated Balance Sheets. Finance lease assets are included in “Property, plant, and equipment, net” and finance lease liabilities are included in “Current portion of long-term debt” and “Long-term debt” in the Company’s Consolidated Balance Sheets. As a practical expedient, short-term leases with an initial term of 12 months or less are excluded from the Consolidated Balance Sheets and charges from these leases are expensed as incurred.

Goodwill Impairment Charges
AsThe Company evaluates goodwill for impairment on an annual basis each year and at an interim date, if indicators of March 31, 2018, accumulatedpotential impairment exist. On October 1, 2019, the Company voluntarily changed its annual goodwill impairment losstesting date from January 1 to October 1 to better align with the timing of the Company’s annual long-term planning process. Accordingly, management determined that the change in accounting principle is preferable under the circumstance. This change has been applied prospectively from October 1, 2019 as retrospective application is deemed impracticable due to the inability to objectively determine the assumptions and significant estimates used in earlier periods without the benefit of hindsight. This change was $1,755 million primarily in our Distribution Solutions segment. As of March 31, 2017,not material to the accumulatedCompany’s consolidated financial statements as it did not delay, accelerate, or avoid any potential goodwill impairment losscharge.
Goodwill impairment testing is conducted at the reporting unit level, which is generally defined as an operating segment or one level below an operating segment (also known as a component), for which discrete financial information is available and segment management regularly reviews the operating results of that reporting unit.
The fair value of the reporting units was $290 million primarilydetermined using a combination of an income approach based on a DCF model and a market approach based on appropriate valuation multiples observed for the reporting unit’s guideline public companies. Fair value estimates result from a complex series of judgments about future events and uncertainties and rely heavily on estimates and assumptions that have been deemed reasonable by management as of the measurement date. Any material changes in our Technology Solutions segment. Referkey assumptions, including failure to Financial Noteimprove operations of certain retail pharmacy stores, additional government reimbursement reductions, deterioration in the financial markets, an increase in interest rates or an increase in the cost of equity financing by market participants within the industry, or other unanticipated events and circumstances, may affect such estimates. The discount rates are the weighted-average cost of capital measuring the reporting unit’s cost of debt and equity financing weighted by the percentage of debt and percentage of equity in a company’s target capital. The unsystematic risk premium is an input factor used in calculating the discount rate that specifically addresses uncertainty related to the reporting unit’s future cash flow projections. Fair value assessments of the reporting unit are considered a Level 3 “Goodwill Impairment Charges,” for more information onmeasurement due to the impairment charges recorded in 2018 and 2017.

FINANCIAL NOTES (Continued)

Goodwill charges listed below were recorded in “Goodwill impairment charges” in the Consolidated Statements of Operations. Most of the goodwill impairment for these reporting units were generally not deductible for income tax purposes.
Fiscal 2021
In the second quarter of 2021, the Company implemented a new segment reporting structure which resulted in 4 reportable segments: U.S. Pharmaceutical, International, Medical-Surgical Solutions, and RxTS. These reportable segments encompass all operating segments of the Company. This segment change prompted changes in multiple reporting units across the Company. As a result, goodwill included in impacted reporting units was reallocated using a relative fair value approach and assessed for impairment both before and after the reallocation.
The Company recorded a goodwill impairment charge of $69 million in 2021 as the estimated fair value of the Europe Retail Pharmacy reporting unit was lower than its reassigned carrying value based on changes in the composition of the Europe Retail Pharmacy reporting unit within the International segment. At March 31, 2021, the balance of goodwill for the reporting units in Europe was approximately NaN and the remaining balance of goodwill in the International segment primarily relates to one of its reporting units in Canada.
The annual impairment testing performed for 2021 did not indicate any impairment of goodwill.
Fiscal 2020
The impairment testing performed in 2020 did not indicate any material impairment of goodwill.
Fiscal 2019
The impairment testing performed in 2019 resulted in the following impairment charges:

(1)As described above, the Company implemented its new segment reporting structure in the second quarter of 2021 and its European Pharmaceutical Solutions segment and its Rexall Health business in Canada became part of the International segment. Amounts included herein were previously included within the former European Pharmaceutical Solutions segment.
(2)Represents pre-tax and after-tax amounts, except for an aggregate $20 million of tax charges related to the March 2019 Retail Pharmacy impairment. Total goodwill impairment for 2019 also included $21 million related to the Company’s Rexall Health business, within the International segment, recorded in the third quarter of 2019.
(3)Prior to implementing its new segment reporting structure in the first quarter of 2019, the Company’s European operations were considered a single reporting unit. Following the change in reportable segments, its European Pharmaceutical Solutions segment was divided into 2 distinct reporting units, Retail Pharmacy (“RP”), formerly Consumer Solutions, and Pharmaceutical Distribution (“PD”), formerly Pharmacy Solutions, for the purposes of goodwill impairment testing. This change required performance of a goodwill impairment test for these 2 new reporting units which resulted in a goodwill impairment charge as PD’s estimated fair value was lower than its reassigned carrying value.
(4)Both RP and PD projected a decline in the estimated future cash flows primarily triggered by U.K. government actions which were announced on June 29, 2018. An interim goodwill impairment test for these reporting units identified that their carrying values exceeded their estimated fair value and resulted in an impairment charge.

FINANCIAL NOTES (Continued)
(5)As a result of the annual goodwill impairment test, the carrying values of the PD and RP reporting units exceeded their estimated fair value which required the Company to record impairment charges for the reporting units. These additional impairments were primarily due to declines in the reporting units’ estimated future cash flows and the selection of higher discount rates. The declines in estimated future cash flows were primarily attributed to additional government reimbursement reductions and competitive pressures within the U.K. The risk of successfully achieving certain business initiatives was the primary factor in the use of a higher discount rate. As of March 31, 2019 the entire remaining goodwill balances of both reporting units were impaired.
Refer to Financial Note 17, “Fair Value Measurements,” for more information on these nonrecurring fair value measurements. As of March 31, 2021 and 2020, accumulated goodwill impairment losses in the Company’s International segment were $3.6 billion and $3.5 billion, respectively.

18.Pension Benefits
We maintain15.    Pension Benefits
The Company maintains a number of qualified and nonqualified defined benefit pension plans and defined contribution plans for eligible employees.
Defined Benefit Pension Plans
Eligible U.S. employees who were employed by theThe Company as of December 31, 1995 are covered under the Company-sponsored defined benefit retirement plan. In 1997, the plan was amended to freeze all plan benefits as of December 31, 1996. Benefits for the defined benefit retirement plan are based primarily on age of employees at date of retirement, years of creditable service and the average of the highest 60 months of pay during the 15 years prior to the plan freeze date. We also have defined benefit pension plans for eligible employees outside of the U.S., as well ashas an unfunded nonqualified supplemental defined benefit plan for certain U.S. executives.executives, as well as benefit pension plans for eligible employees outside the U.S.
OurOn May 23, 2018, the Company’s Board of Directors approved the termination of its frozen U.S. defined benefit pension plan (“Plan”). During the first quarter of 2020, the Company offered the option of receiving a lump sum payment to certain participants with vested qualified Plan benefits in lieu of receiving monthly annuity payments. Approximately 1,300 participants elected to receive the settlement, and lump sum payments of approximately $49 million were made from Plan assets to these participants in June 2019. The benefit obligation settled approximated payments to Plan participants and a settlement charge of $17 million was recorded during the first quarter of 2020. During the second quarter of 2020, the Company transferred the remainder of the Plan’s pension obligation to a third-party insurance provider by purchasing annuity contracts for approximately $280 million which was fully funded directly by Plan assets. The third-party insurance provider assumed the obligation to pay future pension benefits and provide administrative services on November 1, 2019 and a pre-tax settlement charge of $105 million was recorded during the second quarter of 2020. Settlement charges were included within “Other income, net,” in the Consolidated Statements of Operations for the year ended March 31, 2020. As of March 31, 2020, this defined benefit pension plan had an accumulated comprehensive loss of approximately NaN.

FINANCIAL NOTES (Continued)
During the third quarter of 2020, a cash payment of $114 million was made to settle a participant’s liability from the executive benefit retirement plan. As a result, a majority of the remaining recorded unrecognized losses in accumulated other comprehensive loss for this Plan were recognized as expense and a settlement charge of approximately $11 million was recorded in “Other income, net”, in the Consolidated Statements of Operations. As of March 31, 2020 and 2019, this plan had an accumulated comprehensive loss of approximately $1 million and $12 million, respectively.
The Company’s non-U.S. defined benefit pension plans cover eligible employees located predominantly in Norway, the United Kingdom, Germany, and Canada. Benefits for these plans are based primarily on each employee’s final salary, with annual adjustments for inflation. The obligations in Norway are largely related to the state-regulated pension plan which is managed by the Norwegian Public Service Pension Fund (“SPK”). According to the terms of the SPK, the plan assets of state regulated plans in Norway must correspond very closely to the pension obligation calculated using the principles codified in Norwegian law. The shortfall may not exceed 1% of the obligation. If the shortfall exceeds this threshold, it must be remedied within two years. In the United Kingdom, we haveU.K., the Company has subsidiaries that participate in a joint pension plan. This plan is largely funded by contractual trust arrangements that hold Company assets that may only be used to pay pension obligations. The Trustee Board decides on the minimum contribution to the plan in association with selected employees of the entity. A valuation is performed at regular intervals in order to determine the amount of the contribution and to ensure that the minimum contribution is made. The pension obligation in Germany is unfunded with the exception of the contractual trust arrangement used to fund pensions of McKesson Europe’s Management Board.

Plan Assets
Investment Strategy: The overall objective for U. S. pension plan assets is to generate long-term investment returns consistent with capital preservation and prudent investment practices, with a diversification of asset types and investment strategies. Periodic adjustments are made to provide liquidity for benefit payments and to rebalance plan assets to their target allocations.
The target allocations for U.S. plan assets at March 31, 2018 and 2017 are 26% and 50% equity investments, 70% and 45% fixed income investments including cash and cash equivalents and 4% and 5% real estate. Equity investments include common stock, preferred stock, and equity commingled funds. Fixed income investments include corporate bonds, government securities, mortgage-backed securities, asset-backed securities, other directly held fixed income investments, and fixed income commingled funds. The real estate investments are in a commingled real estate fund.
For both U.S. and non-U.S. plan assets, the investment strategies are subject to local regulations and the asset/liability profiles of the plans in each individual country. Plan assets of the non-U.S. plans are broadly invested in a manner appropriate to the nature and duration of the expected future retirement benefits payable under the plans. Plan assets are primarily invested in high-quality corporate and government bond funds and equity securities. Assets are properly diversified to avoid excessive reliance on any particular asset, issuer, or group of undertakings so as to avoid accumulations of risk in the portfolio as a whole.
We developThe Company develops the expected long-term rate of return assumption based on the projected performance of the asset classes in which plan assets are invested. The target asset allocation was determined based on the liability and risk tolerance characteristics of the plans and at times may be adjusted to achieve overall investment objectives.

Other - At March 31, 20182021 and 2017,2020, this includes $38$36 million and $37$29 million, respectively, of plan asset value relating to the SPK. In principle, the SPK is organized as a pay-as-you-go system guaranteed by the Norwegian government as it holds no Company-owned assets to back the pension liabilities. The Company pays a pension premium used to fund the plan, which is paid directly to the Norwegian government who establishes an account for each participating employer to keep track of the financial status of the plan, including managing the contributions and the payments. Further, the investment return credited to this account is determined annually by the SPK based on the performance of long-term government bonds.
The activity attributable to Level 3 plan assets was insignificant innot material for the years ended March 31, 20182021 and 2017.2020.
Multiemployer Plans
The Company contributes to a number of multiemployer pension plans under the terms of collective-bargaining agreements that cover union-represented employees in the U.S. In 2017, weit also contributed to the Pensjonsordningen for Apoteketaten (“POA”), a mandatory multiemployer pension scheme for ourits pharmacy employees in Norway, managed by the association of Norwegian Pharmacies.
The risks of participating in these multiemployer plans are different from single-employer pension plans in the following aspects: (i) assets contributed to the multiemployer plan by one employer may be used to provide benefits to employees of other participating employers; (ii) if a participating employer stops contributing to the plan, the unfunded obligations of the plan may be borne by the remaining participating employers; and (iii) if the Company chooses to stop participating in some of its multiemployer plans, the Company may be required to pay those plans an amount based on the underfunded status of the plan, referred to as a withdrawal liability. Actions taken by other participating employers may lead to adverse changes in the financial condition of a multiemployer benefit plan and ourthe Company’s withdrawal liability and contributions may increase.
Contributions and amounts accrued for U.S. Plans were not material for the years ended March 31, 2018, 2017,2021, 2020, and 2016.2019. Contributions to the POA for non-U.S. Plans exceeding 5% of total plan contributions were $16$22 million,, $18 $17 million, and $23$27 million in 2018, 20172021, 2020, and 2016.2019, respectively. Based on actuarial calculations, we estimatethe Company estimates the funded status for ourits non-U.S. Plans to be approximately 75%78% as of March 31, 2018. No2021. NaN amounts were accrued for liability associated with the POA as we havethe Company has no intention to withdraw from the plan.
Defined Contribution Plans
We haveThe Company has a contributory retirement savings plan (“RSP”) for U.S. eligible employees. Eligible employees may contribute to the RSP up to 75% of their eligible compensation on a pre-tax or post-tax basis not to exceed IRS limits. The Company makes matching contributions in an amount equal to 100% of the employee’s first 3% of pay contributed and 50% for the next 2% of pay contributed. The Company also may make an additional annual matching contribution for each plan year to enable participants to receive a full match based on their annual contribution. The Company also contributed to non-U.S. plans that are available in certain countries. Contribution expenses for the RSP and non-U.S. plans were $82$102 million, $98$102 million, and $99$92 million for the years ended March 31, 2018, 2017,2021, 2020, and 2016.2019, respectively.

19.Postretirement Benefits
We maintainThe Company maintains a number of postretirement benefits, primarily consisting of healthcare and life insurance (“welfare”) benefits, for certain eligible U.S. employees. Eligible employees consist of those who retired before March 31, 1999 and those who retired after March 31, 1999, but were an active employee as of that date, after meeting other age-related criteria. WeIt also provideprovides postretirement benefits for certain U.S. executives. Defined benefit plan obligations are measured as of the Company’s fiscal year-end.

The components of the amount recognized in accumulated other comprehensive income for the Company’s other postretirement benefits at March 31, 2018 and 2017 were net actuarial gains of $8 million and $11 million and net prior service credits of $11 million and $14 million. Other changes in benefit obligations recognized in other comprehensive income were net actuarial gains of $3 million and $14 million in 2018 and 2017 and net prior service credits of $3 million and $3 million in 2018 and 2017.
We estimate that the amortization of the actuarial income from stockholders’ equity to other postretirement gain in 2019 will be $5 million. Comparable 2018 amount was an expense of $6 million.
Other postretirement benefits are funded as claims are paid. Expected benefit payments for our postretirement welfare benefit plans are as follows: $8 million, $7 million, $7 million, $7 million and $7 million for 2019 to 2023 and $28 million cumulatively for 2024 through 2028. Expected benefit payments are based on the same assumptions used to measure the benefit obligations and include estimated future employee service. Expected contributions to be made for our postretirement welfare benefit plans are $8 million for 2019.
Weighted-average discount rates used to estimate postretirement welfare benefit expenses were 3.83%, 3.68% and 3.59% for 2018, 2017 and 2016. Weighted-average discount rates for the actuarial present value of benefit obligations were 3.92%, 3.82% and 3.68% for 2018, 2017 and 2016.
Actuarial gain or loss for the postretirement welfare benefit plan is amortized to income or expense over a three-year period. The assumed healthcare cost trends used in measuring the accumulated postretirement benefit obligation were 3.00% for 2018 and 2017. For 2018, 2017 and 2016, a one-percentage-point increase or decrease in the assumed healthcare cost trend rate would not have a material impact on the postretirement benefit obligations.

In December 2019, the Company entered into a series of forward contracts with a total notional amount of €250 million to offset the earnings impact from its Euro-denominated notes. These contracts and the notes against which they are offsetting matured in February 2020 and were not designated for hedge accounting. Changes in the fair value for contracts not designated as hedges are recorded directly in earnings. In 2020, losses of $44 million were recorded in earnings in “Other income, net” in the Consolidated Statements of Operations, which offset the ineffectiveness on the Company’s non-derivative net investment hedges noted above.

21.Fair Value Measurements
17.    Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participantsValue Measurements
The Company measures certain assets and liabilities at the measurement date. There is a three-level hierarchy that prioritizes the inputs used in determining fair value by their reliabilityin accordance with Accounting Standards Codification (“ASC”) Topic 820, Fair Value Measurements and preferred use,Disclosures. The fair value hierarchy consists of three levels of inputs that may be used to measure fair value as follows:
Level 1 - Valuations based on quoted prices in active markets for identical assets or liabilities.
Level 2 - Valuations based on quoted prices in active markets for similar assets and liabilities, quoted prices for identical or similar assets or liabilities in inactive markets, orsignificant other inputs that are observable or can be corroborated by observable market data.market-based inputs.
Level 3 - Valuations based onsignificant unobservable inputs for which little or no market data exists and requires considerable assumptions that are both significant to the fair value measurementmeasurement.
Assets and unobservable.Liabilities Measured at Fair Value on a Recurring Basis
Cash and cash equivalents at March 31, 2021 and 2020 included investments in money market funds of $1.6 billion and $2.0 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 for the Company’s marketable securities were not material at March 31, 2021 and 2020.

Fair values of the Company’s interest rate 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 16, “Hedging Activities,” for fair value and other information on the Company’s derivatives including interest rate swaps, forward foreign currency contracts and cross-currency swaps.
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 carrying values of $269 million and $170 million at March 31, 2021 and 2020, respectively. These investments primarily consist of equity securities without readily determinable fair values and are included in “Other non-current assets” in the Consolidated Balance Sheets. During 2021, several of the Company’s investments in equity securities without readily determinable fair values experienced transactions which resulted in changes in the observable price of those securities, while others were converted into shares of public common stock through initial public offerings and an acquisition. The Company exited most of its investments in publicly traded shares in the fourth quarter of 2021. Net gains related to the Company’s investments in these equity securities were approximately $133 million for the year ended March 31, 2021. These gains were recorded in “Other income, net” in the Consolidated Statements of Operations. There were no other material changes in the carrying value of these investments during the year ended March 31, 2021. The carrying value of publicly traded investments was determined using quoted prices for identical investments in active markets and are considered to be Level 1 inputs.
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.
At March 31, 20182021, assets measured at fair value on a nonrecurring basis included long-lived assets of the Company’s International segment and 2017,goodwill of the Company’s Europe Retail Pharmacy reporting unit within the International segment.
At March 31, 2020, assets measured at fair value on a nonrecurring basis included long-lived assets of the Company’s International segment. Refer to Financial Note 4, “Restructuring, Impairment, and Related Charges” and Financial Note 12, “Goodwill and Intangible Assets, Net,” for more information.
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 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.
There were 0 liabilities measured at fair value on a nonrecurring basis at March 31, 2021 and 2020.
Other Fair Value Disclosures
At March 31, 2021 and 2020, the carrying amounts of cash, certain cash equivalents, restricted cash, marketable securities, receivables, drafts and accounts payable, short-term borrowings, and other current liabilities approximated their estimated fair values because of the short maturity of these financial instruments.

An impairment charge is recorded when the cost of the asset exceeds its fair value and this condition is determined to be other-than-temporary.
As discussed in Financial Note 4, “Restructuring and Asset Impairment Charges,” we recorded non-cash pre-tax charges of $479 million ($443 million after-tax) during 2018 to impair the carrying values of certain long-lived assets including intangible assets and capitalized software assets. We utilized an income approach (DCF method) or a combination of an income approach and a market approachapproaches for estimating the fair value of intangible assets.

Rent expense under operating leases was $568 million, $474 million and $433 million in 2018, 2017 and 2016. Rent expense increased in 2018 due to our December 2017 acquisition of Rexall Health. We recognize rent expense on a straight-line basis over the term of the lease, taking into account, when applicable, lessor incentives for tenant improvements, periods where no rent payment is required and escalations in rent payments over the term of the lease. Deferred rent is recognized for the difference between the rent expense recognized on a straight-line basis and the payments made per the terms of the lease. Remaining terms for facilities leases generally range from one to sixteen years, while remaining terms for equipment leases range from one to seven years. Most real property leases contain renewal options (generally for five-year increments) and provisions requiring us to pay property taxes and operating expenses in excess of base period amounts.

I. Litigation and Claims Involving Distribution of Controlled Substances
On September 7, 2007, McKesson Specialty Arizona Inc. was servedThe Company and its affiliates are defendants in many cases asserting claims related to distribution of controlled substances. They are named as defendants along with a complaintother pharmaceutical wholesale distributors, pharmaceutical manufacturers, and retail pharmacy chains. The plaintiffs in these actions include state attorneys general, county and municipal governments, tribal nations, hospitals, health and welfare funds, third-party payors, and individuals. These actions have been filed in state and federal courts throughout the New York Supreme Court, New York County by PSKW, LLC,U.S., and in Puerto Rico and Canada. They seek monetary damages and other forms of relief based on a variety of causes of action, including negligence, public nuisance, unjust enrichment, and civil conspiracy, as well as alleging that McKesson Specialty Arizona misappropriated trade secretsviolations of the Racketeer Influenced and confidential information in launching its LoyaltyScript® program, PSKW, LLC v. McKesson Specialty Arizona Inc., Index No. 602921/07.  PSKW later amended its complaint twice to add additional, but related claims. On March 9, 2017, the court entered judgment after trial in McKesson Specialty Arizona’s favor on all claims. On April 6, 2017, PSKW appealed the trial court’s judgment. The appeal was dismissed on March 27, 2018.
On April 16, 2013, the Company’s wholly-owned subsidiary, U.S. Oncology, Inc.Corrupt Organizations Act (“USON”RICO”), was served withstate and federal controlled substances laws, and other statutes.
Since December 5, 2017, nearly all such cases pending in federal district courts have been transferred for consolidated pre-trial proceedings to a third amended qui tam complaint filedmulti-district litigation (“MDL”) in the United States District Court for the Northern District of Ohio captioned In re: National Prescription Opiate Litigation, Case No. 17-md-2804. At present, there are approximately 2,900 cases under the jurisdiction of the MDL court.

FINANCIAL NOTES (Continued)
NaN cases involving McKesson that were previously part of the federal MDL have been remanded to other federal courts for discovery and trial. On January 14, 2020, the Judicial Panel on Multidistrict Litigation finalized its Conditional Remand Order, ordering that the cases brought by Cabell County, West Virginia and the City of Huntington, West Virginia be remanded to the U.S. District Court for the Southern District of West Virginia. Trial in that case began on May 3, 2021. These two West Virginia plaintiffs are not expected to participate in any broader multistate resolution of opioid-related claims. On February 5, 2020, the case brought by the City and County of San Francisco was remanded to the U.S. District Court for the Northern District of California; trial has been set for December 6, 2021. Also on February 5, 2020, the case brought by the Cherokee Nation was remanded by the MDL court to the U.S. District Court for the Eastern District of New YorkOklahoma. The Cherokee Nation is not expected to participate in any broader multistate resolution of opioid-related claims.
The Company is also named in approximately 300 similar state court cases pending in 38 states plus Puerto Rico, along with 3 cases in Canada. These include actions filed by two relators, purportedly26 state attorneys general, and some by or on behalf of individuals, including wrongful death lawsuits, and putative class action lawsuits brought on behalf of children with neonatal abstinence syndrome due to alleged exposure to opioids in utero. Trial dates have been set in several of these state court cases. For example, trial in the Supreme Court of New York, Suffolk County for a case brought by the New York attorney general and 2 New York county governments, is scheduled to begin in June 2021, the cases brought by the Ohio and Washington attorneys general are scheduled to go to trial in September 2021, and the case brought by the Alabama attorney general is scheduled to go to trial in November 2021.
The Company continues to be involved in discussions with the objective of achieving broad resolution of opioid-related claims of states, their political subdivisions and other government entities (“governmental entities”). The Company is in ongoing, advanced discussions with state attorneys general and plaintiffs’ representatives regarding a framework under which, in order to resolve claims of governmental entities, the 3 largest U.S. pharmaceutical distributors would pay up to approximately $21.0 billion over a period of 18 years, with up to approximately $8.0 billion to be paid by the Company, of which more than 90% is anticipated to be used to remediate the opioids crisis. Most of the remaining amount relates to plaintiffs’ attorneys’ fees and costs, and would be payable over a shorter time period. In addition, the proposed framework would require the 3 distributors, including the Company, to adopt changes to anti-diversion programs.
Under the framework, before the distributors determine whether to enter into any final settlement, they would assess the sufficiency of the scope of settlement, based in part on the number and identities of the governmental entities that would participate in any such settlement. The framework contemplates that if certain governmental entities do not agree to a settlement under the framework, but the distributors nonetheless concluded that there was sufficient participation to warrant the settlement, there would be a corresponding reduction in the amount due from the Company to account for the unresolved claims of the governmental entities that do not participate. Those non-participating governmental entities would be entitled to pursue their claims against the Company and other defendants.
The Company disclosed in its financial statements for the quarter ended December 31, 2020 its determination that discussions under that framework reached a stage at which a broad settlement of opioid claims by governmental entities was probable, and for which the loss could be reasonably estimated.
As a result of that conclusion, and its assessment of certain other opioid-related claims, the Company recorded a charge of $8.1 billion ($6.8 billion after-tax) within “Claims and litigation charges, net” in the Consolidated Statements of Operations related to its share of the settlement framework described above, as well as those certain other opioid-related claims. There was no change to the estimated liability as of March 31, 2021.
In light of the uncertainties, as described below, of the timing of amounts that would be paid with respect to these charges, they were recorded in “Long-term litigation liabilities” in the Company’s Consolidated Balance Sheet as of March 31, 2021. In addition, for the same reasons, the amount of loss that the Company ultimately might incur may differ materially from the amounts accrued.

McKESSON CORPORATION
FINANCIAL NOTES (Continued)
Discussions with attorneys general and other parties continue. If the negotiating parties agree on terms under the framework for a broad resolution of claims of governmental entities, then those potential terms would need to be agreed to by numerous other state and local governments before an agreement could be accepted by the Company and finalized. In some cases, discovery has been paused during the parties’ discussions. While the Company continues to be involved in discussions regarding a potential broad settlement framework, the Company also continues to prepare for trial in these pending matters. The Company believes that it has valid defenses to the claims pending against it, and it intends to vigorously defend against all such claims if acceptable settlement terms are not achieved.
Although the vast majority of opioid claims have been brought by governmental entities in the U.S., the Company is also a defendant in cases brought in the U.S. by private plaintiffs, such as hospitals, health and welfare funds, third-party payors, and individuals, as well as 3 cases brought by governmental entities in Canada. These claims, and those of private entities generally, are not included in the settlement framework for governmental entities, or in the charges recorded by the Company, described above. The Company believes it has valid legal defenses in these matters and intends to mount a vigorous defense. The Company has not concluded a loss is probable in any of these matters; nor is the amount of any loss reasonably estimable.
Because of the many uncertainties associated with any potential settlement arrangement or other resolution of all of these opioid-related litigation matters, including the uncertain scope of participation by governmental entities in any potential settlement under the framework described above, the Company is not able to reasonably estimate the upper or lower ends of the range of ultimate possible loss for all opioid-related litigation matters. An adverse judgment or negotiated resolution in any of these matters could have a material adverse impact on the Company’s financial position, cash flows or liquidity, or results of operations.
On August 8, 2018, the Company was served with a qui tam complaint pending in the United States 21 states andDistrict Court for the District of Columbia, against USON and five other defendants,Massachusetts alleging that USON solicited and received illegal “kickbacks” from Amgen in violation of the Anti-Kickback Statute,Company violated the federal False Claims Act and various state false claims statutes,acts due to the alleged failure of the Company and seeking damages, treble damages, civil penalties, attorneys’ fees and costsother defendants to report providers who were engaged in diversion of suit, all in unspecified amounts, controlled substances.

Legislative, regulatory or industry measures to investigations aboutaddress the misuse of prescription opioid medications could affect the Company’s suspicious order reporting practicesbusiness in ways that it may not be able to predict. For example, in April 2018, the State of New York adopted the Opioid Stewardship Act (the “OSA”) which required the creation of an aggregate $100 million annual surcharge on all manufacturers and distributors licensed to sell or distribute opioids in New York. The initial surcharge payment would have been due on January 1, 2019 for controlled substances. In Januaryopioids sold or distributed during calendar year 2017. On July 6, 2018, the Healthcare Distribution Alliance filed a lawsuit challenging the constitutionality of the law and seeking an injunction against its enforcement. On December 19, 2018, the U.S. District Court for the Southern District of New York found the law unconstitutional and issued an injunction preventing the State of New York from enforcing the law. The State appealed that decision. On September 14, 2020, a panel of the U.S. Court of Appeals for the Second Circuit reversed the district court’s decision on procedural grounds. The Company has accrued a $50 million pre-tax charge ($37 million after-tax) as its estimated share of the OSA surcharge for calendar years 2017 and 2018. This OSA provision was recognized in “Selling, distribution, general, and administrative expenses” in the Company finalizedConsolidated Statement of Operations for the settlementsyear ended March 31, 2021 and paid $150 million in cash.“Other accrued liabilities” in the Consolidated Balance Sheet as of March 31, 2021. The State of New York adopted an excise tax on sales of opioids in the State, which became effective July 1, 2019. The law adopting the excise tax made clear that the OSA does not apply to sales or distributions occurring after December 31, 2018. The Healthcare Distribution Alliance filed a petition for panel rehearing, or, in the alternative, for rehearing en banc with the U.S. Court of Appeals for the Second Circuit; that petition was denied on December 18, 2020. On February 12, 2021, the Court of Appeals for the Second Circuit granted a motion by the Healthcare Distribution Alliance to stay its mandate pending the filing and disposition of a petition for writ of certiorari before the U.S. Supreme Court. The due date for filing such a petition is May 17, 2021.

V. Environmental Matters
Primarily as a result of the operation of the Company’s former chemical businesses, which were fully divested by 1987, the Company is involved in various matters pursuant to environmental laws and regulations. The Company has received claims and demands from governmental agencies relating to investigative and remedial actions purportedly required to address environmental conditions alleged to exist at five5 sites where it, or entities acquired by it, formerly conducted operations and the Company, by administrative order or otherwise, has agreed to take certain actions at those sites, including soil and groundwater remediation.
Based on a determination by the Company’s environmental staff, in consultation with outside environmental specialists and counsel, the current estimate of the Company’s probable loss associated with the remediation costs for these five5 sites is $9.5$10 million, net of amounts anticipated from third parties. The $9.5$10 million is expected to be paid out between April 20182021 and March 2048.2051.

In addition, theThe Company has been designated as a Potentially Responsible Party (“PRP”) under the Superfund law for environmental assessment and cleanup costs as the result of its alleged disposal of hazardous substances at 14 sites. With respect to these sites, numerous other PRPs have similarly been designated and while the current state of the law potentially imposes joint and several liabilityliabilities upon PRPs, as a practical matter, costs of these sites are typically shared with other PRPs. At one1 of these sites, the United States Environmental Protection Agency has selected a preferred remedy with an estimated cost of approximately $1.38$1.4 billion. It is not certain at this point in time what proportion of this estimated liability will be borne by the Company or by the numerous other PRPs.Company. Accordingly, the Company’s estimated probable loss at those 14 sites is approximately $21.6$28 million, which has been entirely accrued for in the accompanying consolidated balance sheets.Consolidated Balance Sheets.

30.Subsequent Events
On April 25, 2018, the Company announced a multi-year strategic growth initiative. As part of the preliminary phase of this initiative, in April 2018, we committed to a restructuring plan to optimize our operating model and cost structure which will be substantially implemented by the end of 2019. We expect to record total after-tax charges of approximately $150 million to $210 million during 2019. The charges under this plan primarily consist of employee severance, exit-related costs and other charges.

On April 25, 2018, we entered into a definitive agreement to purchase Medical Specialties Distributors LLC (“MSD”) for $800 million, which will be funded from cash on hand. MSD is a leading national distributor of infusion and medical-surgical supplies as well as provider of biomedical services to alternate site and home health providers. The acquisition is subject to regulatory approval and expected to close during the first half of 2019. Upon closing, the financial results of MSD will be included in our consolidated statements of operations within our Medical-Surgical Solutions business.
On May 23, 2018, the Company’s Board of Directors approved the termination of our frozen U.S. defined benefit pension plan (“Plan”).  The distribution of plan assets pursuant to the termination will not be made until the plan termination satisfies all regulatory requirements, which is expected to be completed by the second half of 2020. Plan participants will receive their full accrued benefits from plan assets by electing either lump sum distributions or annuity contracts with a qualifying third-party annuity provider. The plan termination is expected to result in a one-time expense primarily representing pension settlement, which will be determined based on prevailing market conditions, the actual lump sum distributions and annuity purchase rates at the date of distribution. As a result, we are currently unable to reasonably estimate timing nor the amount of such settlement charges. As of March 31, 2018, this defined benefit pension plan had an accumulated comprehensive loss of approximately $120 million.

2000 Employee Stock Purchase Plan (the “ESPP”): The ESPP is intended to qualify as an “employee stock purchase plan” within the meaning of Section 423 of the Internal Revenue Code. In March 2002, the Board amended the ESPP to allow for participation in the plan by employees of certain of the Company’s international and other subsidiaries. As to those employees, the ESPP does not qualify under Section 423 of the Internal Revenue Code. Currently, 21.1 million shares have been approved by stockholders for issuance under the ESPP.

Table of Contents
McKESSON CORPORATION

The ESPP is implemented through a continuous series of three-month purchase periods (“Purchase Periods”) during which contributions can be made toward the purchase of common stock under the plan.
Each eligible employee may elect to authorize regular payroll deductions during the next succeeding Purchase Period, the amount of which may not exceed 15% of a participant’s compensation. At the end of each Purchase Period, the funds withheld by each participant will be used to purchase shares of the Company’s common stock. The purchase price of each share of the Company’s common stock is 85% of the fair market value of each share on the last day of the applicable Purchase Period. In general, the maximum number of shares of common stock that may be purchased by a participant for each calendar year is determined by dividing $25,000 by the fair market value of one share of common stock on the offering date.
There currently are no equity awards outstanding that were granted under equity plans that were not submitted for approval by the Company’s stockholders.
