[removed: Continued volatility] [added: These risks, as well as changes] in the availability, pricing [removed: trends or] [added: volatility,] reimbursement [removed: of these] [added: rates for] generic drugs, or significant [removed: fluctuations] [added: changes] in the nature, frequency [removed: and] [added: or] magnitude of generic pharmaceutical launches, [removed: could] [added: might] have a [removed: material] [added: materially] adverse impact on our [added: business operations and our financial position or] results of operations.

Rewritten

[removed: The healthcare] [added: Our] 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.

[removed: McKESSON CORPORATION][added: McKESSON CORPORATION]

Rewritten

[removed: Healthcare Fraud: We] [added: We] are subject to extensive and frequently changing local, state and federal laws and regulations relating to healthcare fraud, waste and [removed: abuse.][added: abuse.]

Rewritten

Our relationships with pharmaceutical and [removed: medical-surgical] [added: medical 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 [removed: a number of] [added: many] 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.

Rewritten

Many of [removed: the regulations applicable to us,] [added: these laws,] including those relating to marketing incentives, are vague or indefinite and have not been interpreted by the courts.

[removed: If finalized, the proposal would create] [added: These proposals might result in] significant [removed: change] [added: 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.

Rewritten

[removed: Operating, Security and Licensure Standards:] 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.

Rewritten

[removed: In] [added: For example, under a] January [removed: 2017, we reached an] [added: 2017] agreement with the DEA and Department of Justice [removed: pursuant to which] we paid $150 million to settle [removed: all] potential administrative and civil claims [removed: relating to investigations] about [removed: the Company’s suspicious order reporting] [added: our] practices for [added: reporting suspicious orders of] controlled [removed: substances.][added: substances and the DEA suspended, on a staggered basis for limited periods of time, our registrations to distribute certain controlled substances from four distribution centers.]

Rewritten

[removed: Pedigree Tracking:] There have been increasing efforts by [removed: Congress and state and federal agencies, including state boards of pharmacy and departments of health and the FDA,] [added: 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.

Rewritten

[removed: In addition,] [added: For example,] the [added: 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 [removed: technologies for the purpose of securing] [added: technologies, such as track and trace or authentication technologies, to secure] the pharmaceutical supply chain against counterfeit drugs.

Rewritten

[removed: The DQSA and other pedigree] [added: Pedigree] tracking laws [removed: and regulations could] [added: such as these] increase [removed: the overall regulatory] [added: our compliance] burden and [removed: costs associated with] our pharmaceutical distribution [removed: business,] [added: costs,] and [removed: could] [added: they might] have a [removed: material] [added: materially] adverse impact on our [added: business operations and our financial position or] results of operations.

Rewritten

[removed: In particular, regulations promulgated pursuant to] [added: For example, under] the Health Insurance Portability and Accountability Act of 1996 (“HIPAA”) [removed: 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 of] [added: we must maintain] administrative, physical and technological safeguards to protect [removed: the privacy of protected] [added: individually identifiable] health information [added: (“protected health information”)] and ensure the confidentiality, integrity and availability of electronic protected health information.

Rewritten

[removed: Healthcare Reform: The] [added: 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.

Rewritten

[removed: Our foreign operations subject us to a number] [added: Any] of [removed: operating, economic, political and regulatory] [added: these] risks [removed: that may] [added: might] have a [removed: material] [added: materially] adverse impact on our [added: business operations and our] financial position [removed: and] [added: or] results of operations.

Rewritten

[removed: In addition, foreign operations] [added: We] are [removed: also] subject to [removed: 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.

Rewritten

[removed: Failure] [added: Our failure] to comply with these laws [removed: could] [added: might] subject us to civil and criminal penalties that [removed: could] [added: might] have a [removed: material] [added: materially] adverse impact on our [added: business operations and our] financial position [removed: and] [added: or] results of operations.

Rewritten

[removed: For example, the] [added: The] FDA [removed: has conducted investigations and] banned certain [removed: generics] manufacturers from selling [removed: certain] raw materials and drug ingredients in the U.S. [removed: from overseas plants] due to quality issues.

Rewritten

Difficulties in [added: product] manufacturing or access to raw materials could result in [added: supplier] production shutdowns, product shortages and other [removed: similar delays in product manufacturing that could have a material adverse impact on our financial position and results of operations.][added: supply disruptions.]

Rewritten

Provincial governments in Canada [added: that] provide partial funding for the purchase of pharmaceuticals and independently regulate the sale and reimbursement of [removed: drugs.][added: drugs have sought to reduce the costs of publicly funded health programs.]

[removed: In addition, in many] [added: Many] European [removed: countries the government provides] [added: governments provide] or [removed: subsidizes] [added: subsidize] healthcare to consumers and [removed: regulates] [added: regulate] pharmaceutical prices, patient [removed: eligibility,] [added: eligibility] and reimbursement levels [added: in order] to control [removed: costs for the government-sponsored] [added: government] healthcare [removed: system.][added: system costs.]

Rewritten

These [removed: measures, which include efforts aimed at reforming healthcare coverage and reducing healthcare costs, continue to] [added: measures] exert pressure on the pricing [removed: of] and reimbursement timelines for pharmaceuticals and may cause our customers to purchase fewer of our products and services [removed: and reduce the prices they are willing] [added: or influence us] to [removed: pay.][added: reduce prices.]

Rewritten

[removed: In Europe, we] [added: We] are subject to [added: significant compliance obligations under privacy laws such as] the General Data Protection Regulation [removed: (“GDPR”) and] in [removed: Canada, we are subject to] the [added: European Union (“GDPR”), the] Personal Information Protection and Electronic Documents Act [removed: (“PIPEDA”).][added: (“PIPEDA”) in Canada, and the California Consumer Protection Act (“CCPA”).]

New in FY2020

The discussion below identifies certain representative risks that might cause our actual business results to materially differ from our estimates.

New in FY2020

It is not practical to identify or describe all risks and uncertainties that might materially impact our business operations, reputation, financial position or results of operations.

New in FY2020

Our business could be materially affected by risks that we have not yet identified or that we currently consider to be immaterial.

New in FY2020

Litigation and Regulatory Risks

New in FY2020

We experience costly and disruptive legal disputes.

New in FY2020

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 21, “Commitments and Contingent Liabilities,” to the consolidated financial statements in this report.

New in FY2020

Regulatory proceedings might involve allegations such as false claims, healthcare fraud and abuse, and antitrust violations.

New in FY2020

Civil litigation proceedings might involve commercial, employment, environmental, intellectual property, tort and other claims.

New in FY2020

The outcome of legal disputes is difficult to predict.

New in FY2020

Accordingly, any legal dispute might have a materially adverse impact on our reputation, our business operations and our financial position or results of operations.

New in FY2020

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.

New in FY2020

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.

New in FY2020

We experience costly legal disputes, government actions and adverse publicity regarding our role in distributing controlled substances such as opioids.

New in FY2020

The Company is a defendant in over 3,000 cases alleging claims related to the distribution of controlled substances (opioids), as described in Financial Note 21, “Commitments and Contingent Liabilities,” to the consolidated financial statements in this report.

New in FY2020

We regularly are named as a defendant in similar, new cases.

New in FY2020

The plaintiffs in those cases include governmental entities (such as states, provinces, counties and municipalities) as well as businesses, groups and individuals.

New in FY2020

The cases allege violations of controlled substance laws and other laws, and they make common law claims such as negligence and public nuisance.

New in FY2020

Many of these cases raise novel theories of liability.

New in FY2020

Any proceedings can have unexpected outcomes that are not justified by evidence or existing law.

New in FY2020

All proceedings involve significant expense, management time and distraction, and risk of loss that can be difficult to predict or quantify.

New in FY2020

It is not uncommon for claims to be resolved over many years.

New in FY2020

Proceedings can result in monetary damages, penalties and fines, and injunctive or other relief.

New in FY2020

Although the Company has valid defenses and is vigorously defending itself, some proceedings are resolved by negotiated outcome.

New in FY2020

Our reputation is impacted by publicity regarding the impacts of opioid use.

New in FY2020

We might experience increased costs to distribute controlled substances such as opioids.

New in FY2020

Legislative, 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.

New in FY2020

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.

New in FY2020

Liabilities for taxes or assessments or other costs of compliance under any such laws might have a materially adverse impact on our business operations and our financial position or results of operations.

New in FY2020

[Table of Contents](#s8AE717A86E6C5AD0BF7B80E343BCFC51)

New in FY2020

We are subject to extensive, complex and challenging healthcare and other laws.

New in FY2020

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.

New in FY2020

These sanctions might have a materially adverse impact on our business operations and our financial position or results of operations.

New in FY2020

We might lose our ability to purchase, compound, store or distribute pharmaceuticals and controlled substances.

New in FY2020

Noncompliance with these requirements has resulted in monetary penalties and/or licensing sanctions.

New in FY2020

As of March 31, 2020, one DEA registration was in suspension, and three were expired.

New in FY2020

If we are not able to obtain, maintain or renew permits, licenses or other regulatory approvals needed for the operation of our businesses, it might have a materially adverse impact on our business operations and our financial position or results of operations.

New in FY2020

Pedigree tracking laws increase our compliance burden and our pharmaceutical distribution costs.

New in FY2020

We also have record-keeping and other obligations under the E.U. Falsified Medicines Directive.

McKESSON CORPORATION

Dropped from FY2019

Although it is not possible to predict or identify all such risks and uncertainties, they may include, but are not limited to, the factors discussed below.

Dropped from FY2019

Our business operations could also be affected by additional factors that are not presently known to us or that we currently consider not to be material.

Dropped from FY2019

Changes in the United States healthcare industry and regulatory environment could have a material adverse impact on our results of operations.

Dropped from FY2019

We expect the healthcare industry in the United States to continue to change and for healthcare delivery models to evolve in the future.

Dropped from FY2019

Additionally, if we experience disruptions in our supply of generic drugs, our margins could be adversely affected.

Dropped from FY2019

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.

Dropped from FY2019

Failure to successfully renew these contracts in a timely and favorable manner could have a material adverse impact on our results of operations.

Dropped from FY2019

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.

Dropped from FY2019

In addition, we distribute generic pharmaceuticals, which can be subject to both price deflation and price inflation.

Dropped from FY2019

Our generic pharmaceutical sourcing program has benefited from sourcing through our joint venture with Walmart, Inc., ClarusONE.

Dropped from FY2019

If ClarusONE does not continue to be successful, our margins could be adversely affected.

Dropped from FY2019

Our U.S. Pharmaceutical and Specialty Solutions segment experienced weaker pharmaceutical pricing trends over the last three years.

Dropped from FY2019

Additionally, any future changes in branded and generics drug pricing could be significantly different than our projections.

Dropped from FY2019

Generic drug manufacturers are increasingly challenging the validity or enforceability of patents on branded pharmaceutical products.

Dropped from FY2019

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.

Dropped from FY2019

To the extent we source, contract manufacture, and distribute such generic products, the brand-name company could assert infringement claims against us.

Dropped from FY2019

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.

Dropped from FY2019

For example, on October 25, 2018, the Department of Health & Human Services (“HHS”) announced its intent to propose an International Pricing Index (“IPI”) payment model to reduce government payments for Medicare Part B drugs to levels more closely aligned with prices paid in other countries.

Dropped from FY2019

If proposed and finalized, the far-reaching model could reduce Part B drug reimbursement by 30 percent between 2020 and 2025.

Dropped from FY2019

The model would eliminate the “buy and bill” model and reintroduce the Competitive Acquisition Program (“CAP”).

Dropped from FY2019

This could allow private vendors (including non-wholesaler entities) to procure and distribute drugs to physicians and hospitals, while Medicare would pay the vendor for the included drugs based on the target price driven by the IPI.

Dropped from FY2019

Also, on January 31, 2019, the HHS Office of Inspector General released the Removal of Safe Harbor Protection for Rebates to Plans or Pharmacy Benefit Managers (“PBM”) Involving Prescription Pharmaceuticals and Creation of New Safe Harbor Protection Proposed Rule.

Dropped from FY2019

Additionally, federal and state lawmakers are increasingly exploring other policy proposals to reduce drug price, including price transparency measurers and drug reimportation.

Dropped from FY2019

There can be no assurance that the preceding changes would not have a material adverse impact on our results of operations.

Dropped from FY2019

As part of these operating, security and licensure standards, we regularly receive requests for information and occasionally subpoenas from government authorities.

Dropped from FY2019

In some instances, these can lead to monetary penalties and/or license revocation.

Dropped from FY2019

The DEA suspended, on a staggered basis for limited periods of time, McKesson’s DEA registrations to distribute certain controlled substances from four McKesson distribution centers.

Dropped from FY2019

As of March 31, 2019, staggered suspensions have expired for two DEA registrations and two remain applicable.

Dropped from FY2019

Although we have enhanced our procedures to ensure compliance, there can be no assurance that a regulatory agency or tribunal would conclude that our operations are compliant with applicable laws and regulations.

Dropped from FY2019

In addition, there can be no assurance that we will be able to maintain or renew existing permits, licenses or any other regulatory approvals or obtain without significant delay future permits, licenses or other approvals needed for the operation of our businesses.

Dropped from FY2019

In November 2013, Congress passed and the President signed into law the Drug Quality and Security Act (“DQSA”).

Dropped from FY2019

The DQSA establishes federal standards requiring supply-chain stakeholders to participate in a prescription drug track and trace system.

Dropped from FY2019

Track and trace began in 2015 at the lot-level and evolves to a serialized level electronic, interoperable system by November 2023.

Dropped from FY2019

The law also preempts state drug pedigree requirements.

Dropped from FY2019

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.

Dropped from FY2019

These standards may include track and trace or authentication technologies, such as radio frequency identification devices, 2D data matrix barcodes and other similar technologies.

Dropped from FY2019

On March 26, 2010, the FDA released the Serialized Numerical Identifier (“SNI”) guidance for manufacturers who serialize pharmaceutical packaging.

Dropped from FY2019

We expect to be able to accommodate these SNI regulations in our distribution operations.

Dropped from FY2019

Privacy: There are numerous federal and state laws and regulations related to the privacy and security of personal information.

Dropped from FY2019

We are directly subject to certain provisions of the regulations as a “Business Associate” through our relationships with customers.

New in FY2020

We are a global leader in healthcare supply chain management solutions, retail pharmacy, community oncology and specialty care, and healthcare technology.

New in FY2020

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.

New in FY2020

All remaining operating segments and business activities that are not significant enough to require separate reportable segment disclosure are included in Other, which primarily consists of McKesson Canada, McKesson Prescription Technology Solutions (“MRxTS”) and our investment in Change Healthcare LLC (“Change Healthcare JV”), which was split-off from the Company in the fourth quarter of 2020 as further discussed in this Financial Review.

New in FY2020

Our organizational structure also includes Corporate, which consists of income and expenses associated with administrative functions and projects, and the results of certain investments.

New in FY2020

The factors for determining the reportable segments include the manner in which management evaluates the performance of the Company combined with the nature of the individual business activities.

New in FY2020

We evaluate the performance of our operating segments on a number of measures, including revenues and operating profit before interest expense and income taxes.

New in FY2020

Executive Summary:

New in FY2020

The following executive summary provides highlights and key factors that impacted our business, operating results and liquidity for the year ended March 31, 2020.

New in FY2020

The coronavirus disease 2019 (“COVID-19”) did not significantly impact our financial condition, results of operations or liquidity in 2020.

New in FY2020

For a more in-depth discussion of how COVID-19 impacted our business, operations, and outlook, see the COVID-19 section of "Trends and Uncertainties" included below.

New in FY2020

| • | Revenues of $231.1 billion, reflecting an 8% increase from the prior year driven primarily by market growth in our U.S. Pharmaceutical and Specialty Solutions segment, including branded pharmaceutical price increases and higher volumes from retail national account customers; |

New in FY2020

| • | Gross profit increased 2% from the prior year primarily driven by market growth in our Medical-Surgical Solutions segment; |

New in FY2020

| • | On October 21, 2019, we disclosed an opioid-related litigation settlement with two Ohio counties and recorded a related charge of $82 million in total operating expenses; |

New in FY2020

| • | On December 12, 2019, McKesson and Walgreens Boots Alliance announced an agreement to create a joint venture that is expected to combine their respective pharmaceutical wholesale businesses in Germany. As a result of this agreement, we recognized fair value remeasurement charges of $275 million in total operating expenses within our European Pharmaceutical Solutions segment; |

New in FY2020

| • | On March 10, 2020, we completed the previously announced separation of our investment in Change Healthcare JV and recognized an estimated gain of $414 million related to this transaction. We no longer hold an interest in any securities of Change Healthcare JV or Change Healthcare, Inc. (“Change”) following the separation. During the second quarter of 2020, we recorded an other-than-temporary-impairment (“OTTI”) charge of $1.2 billion and a dilution loss of $246 million related to our investment in Change Healthcare JV; |

New in FY2020

| • | Diluted earnings per common share from continuing operations attributable to McKesson Corporation in 2020 of $4.99 reflects the aforementioned items and a lower share count compared to the prior year driven largely by share repurchases; and |

New in FY2020

| • | We returned $2.2 billion of cash to shareholders through $1.9 billion of common stock repurchases and $294 million of dividend payments. |

New in FY2020

Trends and Uncertainties:

New in FY2020

COVID-19

New in FY2020

In December 2019, a novel strain of coronavirus, which causes the infectious disease known as COVID-19, was reported in Wuhan, China.

New in FY2020

The World Health Organization declared COVID-19 a “Public Health Emergency of International Concern” on January 30, 2020 and a global pandemic on March 11, 2020.

New in FY2020

We continue to evaluate the nature and extent COVID-19 may have to our business and operations.

New in FY2020

The pandemic is developing rapidly and the full extent to which COVID-19 will impact us depends on future developments, including the duration and spread of the virus, as well as potential seasonality of new outbreaks.

New in FY2020

In response to the COVID-19 pandemic, federal, state, and local government directives and policies have been put in place in the United States 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 new healthcare challenge.

New in FY2020

Similar governmental actions have occurred in Canada and Europe.

New in FY2020

As a global leader in healthcare supply chain management solutions, retail pharmacy, community oncology and specialty care, and healthcare information technology, we are uniquely positioned to respond to the COVID-19 pandemic in the United States, Canada, and Europe.

New in FY2020

We are working closely with national and local governments, agencies, and industry partners to ensure supplies, including personal protective equipment, and medicine reach our customers and patients when they need them.

McKESSON CORPORATION

New in FY2020

FINANCIAL REVIEW (Continued)

New in FY2020

We have taken the necessary steps to ensure that we continue to supply our customers and protect the safety of our employees.

New in FY2020

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 requirements, employee support programs, and enhanced safety measures are intended to limit exposure to COVID-19.

New in FY2020

These successful steps in our fourth quarter of 2020 have resulted in limited disruption of our normal business operations, productivity trends, and slightly compressed operating margins due to increased operating expenses.

New in FY2020

The financial impact to the year ended March 31, 2020 is muted due to the timing of the COVID-19 pandemic late in our fourth quarter.

New in FY2020

We experienced higher pharmaceutical distribution volumes in March, however, these increases were partially offset by decreases in specialty drug volumes and decreased demand within primary care medical-surgical supplies.

New in FY2020

Specialty drug volumes were negatively impacted by lower demand for infusions, elective specialty drugs, oncology, and dermatology practice sales.

New in FY2020

Demand for primary care medical-surgical supplies were negatively impacted by deferrals in elective procedures in hospitals and surgery centers as well as decreased traffic or closures in doctor’s offices.

New in FY2020

These positive and negative COVID-19 impacts drove increased consolidated revenues by less than 1% in 2020.

Dropped from FY2019

All remaining operating segments and business activities that are not significant enough to require separate reportable segment disclosure are included in Other.

Dropped from FY2019

Overview:

Dropped from FY2019

| | | | | | | | | | | | | | | | | | | | |

Dropped from FY2019

| --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- |

Dropped from FY2019

| Operating Expenses | $ | (8,474 | ) | | $ | (8,263 | ) | | $ | (7,788 | ) | | 3 | | % | | 6 | | % |

Dropped from FY2019

The increase in revenue for 2018 was also offset by the 2017 contribution of the majority of our McKesson Technology Solutions businesses (“Core MTS Business”) to form the Change Healthcare joint venture.

Dropped from FY2019

Gross profit and gross profit margin decreased in 2018 compared to 2017.

Dropped from FY2019

The decrease was primarily due to the 2017 contribution of the Core MTS Business to the Change Healthcare joint venture, significant government reimbursement reductions in the U.K., the competitive sell-side environment and weaker pharmaceutical manufacturer pricing trends.

Dropped from FY2019

These decreases in 2018 were partially offset by market growth, procurement benefits realized through the joint sourcing entity, ClarusONE Sourcing Services LLP (“ClarusONE”), higher LIFO credits and our business acquisitions.

Dropped from FY2019

Gross profit for 2017 benefited from $144 million of cash receipts representing our share of antitrust legal settlements.

Dropped from FY2019

Operating Expenses:

Dropped from FY2019

Operating expenses, and operating expenses as a percentage of revenues increased in 2019 and 2018.

Dropped from FY2019

| • | Non-cash pre-tax long-lived asset impairment charges of $245 million ($207 million after-tax) primarily for our U.K. business (mainly pharmacy licenses) driven by additional government reimbursement reductions and competitive pressures in the U.K.; |

Dropped from FY2019

| • | Higher opioid-related costs of $151 million ($122 million after-tax) primarily related to litigation expenses. 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. In addition, the State of New York has recently adopted a tax on sales of opioids in the State, and other states are considering legislation that could require us to pay taxes, licensing fees, or assessments on the distribution of opioid medications in those states. Liabilities for taxes or assessments under any such laws will likely have an adverse impact on our results of operations, unless we are able to mitigate them through operational changes or commercial arrangements where permitted. Refer to Financial Note 24, “Commitments and Contingent Liabilities,” to the accompanying consolidated financial statements appearing in this Annual Report on Form 10-K for more information; |

Dropped from FY2019

| • | Pre-tax restructuring charges of $74 million ($67 million after-tax) primarily representing employee severance and lease exit costs related to the 2018 restructuring plan for our McKesson Europe business. Under this plan, we expect to record total pre-tax charges of approximately $90 million to $130 million, of which $92 million of pre-tax charges were recorded to date; |

Dropped from FY2019

| • | Higher expenses due to our business acquisitions; |

Dropped from FY2019

2017

Dropped from FY2019

| • | Pre-tax gain of $3,947 million ($3,018 million after-tax) related to the 2017 contribution of the Core MTS Business to the Change Healthcare joint venture; and |

Dropped from FY2019

| • | Non-cash pre-tax goodwill impairment charge of $290 million ($282 million after-tax) related to our EIS business within Other. This impairment charge was generally not deductible for income tax purposes. |

Dropped from FY2019

We expect to record total pre-tax charges of approximately $140 million to $180 million, of which we recorded pre-tax charges of $135 million ($122 million after-tax) in 2019.

Dropped from FY2019

This set of the initiatives will be substantially completed by the end of 2020.

Dropped from FY2019

We expect to incur total pre-tax charges of approximately $300 million to $350 million for these programs, which are expected to be completed by the end of 2021.

Dropped from FY2019

In 2019, pre-tax charges of $163 million ($127 million after-tax) were recorded, which primarily represent employee severance and accelerated depreciation expense.

Dropped from FY2019

Acquisition-Related Expenses and Adjustments

Dropped from FY2019

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 $228 million and $168 million in 2019 and 2018, and net credit of $3,797 million in 2017.

Dropped from FY2019

2019 and 2018 include our proportionate share of transaction and integration expenses incurred by Change Healthcare.

Critical Audit Matters

New in FY2020

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.

New in FY2020

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.

New in FY2020

Contingent Liabilities - Litigation and Claims involving Distribution of Controlled Substances - Refer to Note 21 to the financial statements

New in FY2020

*Critical Audit Matter Description*

New in FY2020

The Company is named as a defendant along with other pharmaceutical wholesale distributors, pharmaceutical manufacturers and retail pharmacy chains.

New in FY2020

When a loss is considered probable and reasonably estimable, the Company records a liability in the amount of its estimate for the ultimate loss.

New in FY2020

The Company also performs an assessment of loss contingencies where a loss is reasonably possible.

New in FY2020

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.

New in FY2020

As of March 31, 2020, the Company has determined that a liability associated with these claims, whether through settlement or litigation, is not probable and a loss or range of loss is not reasonably estimable.

New in FY2020

We identified litigation and claims involving the distribution of controlled substances as a critical audit matter because of the challenges auditing management’s judgments applied in determining the likelihood of loss related to the resolution of such claims.

New in FY2020

Specifically, auditing management’s determination of whether any contingent loss arising from the related litigation and claims is probable, reasonably possible, or remote, and the related disclosures, is subjective and requires significant judgment due to the large number of parties involved, together with the novelty and complexity of the issues.

New in FY2020

*How the Critical Audit Matter Was Addressed in the Audit*

New in FY2020

Our audit procedures related to litigation and claims involving distribution of controlled substances included the following, among others:

New in FY2020

| • | We tested the effectiveness of internal controls related to management’s review of litigation and claims involving the distribution of controlled substances, and approval of the accounting treatment and related disclosures based on the most recent facts and circumstances. |

New in FY2020

| • | We inquired of the Company’s internal and external legal counsel to understand the basis for the Company’s conclusion that any potential loss from the litigation and claims involving the distribution of controlled substances, including through broad resolution via settlement, is neither probable nor reasonably estimable as of March 31, 2020. In addition, we requested and received a written response from internal and external legal counsel as it relates to litigation and claims involving the distribution of controlled substances. |

New in FY2020

| • | We evaluated management’s analysis of litigation and claims involving the distribution of controlled substances, read Board of Directors meeting minutes, including relevant sub-committee meeting minutes, and compared to responses from internal and external counsel. As part of our procedures, we also performed public domain searches for evidence contrary to management’s analysis. |

New in FY2020

| • | We compared the Company's assessment of this matter to relevant history of similar legal contingencies that have been settled or otherwise resolved to evaluate the consistency of the Company's assessment of litigation and claims involving the distribution of controlled substances at March 31, 2020. |

New in FY2020

| • | We consulted with our auditing and accounting experts to assist in our evaluation of the case facts and the Company’s related accounting treatment for the litigation and claims involving the distribution of controlled substances. |

New in FY2020

| • | We evaluated any events subsequent to March 31, 2020 that might impact our evaluation of litigation and claims involving the distribution of controlled substances, including any related accrual or disclosure. |

New in FY2020

| • | We obtained written representations from executives and internal counsel of the Company. |

New in FY2020

| • | We read the Company’s related disclosures and evaluated them for consistency with our testing. |

Goodwill - Refer to Note 14 to the financial statements

New in FY2020

*Critical Audit Matter Description*

New in FY2020

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.

New in FY2020

The Company uses a combination of the income and market approaches to estimate reporting unit fair value.

New in FY2020

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.

New in FY2020

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.

New in FY2020

The goodwill balance was $9.4 billion as of March 31, 2020, of which $1.4 billion was allocated to the McKesson Canada reporting unit.

New in FY2020

The fair value of all reporting units exceeded their respective carrying amounts as of the measurement date and, therefore, no impairment was recognized.

New in FY2020

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.

New in FY2020

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.

New in FY2020

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.

The goodwill testing requires us to compare the estimated fair value of a reporting unit to its carrying value.

Dropped from FY2019

If the carrying value of the reporting unit is lower than its estimated fair value, no further evaluation is required.

In the fourth quarter of 2018, we adopted amended guidance for derivatives and hedging which eliminates the existing requirement to recognize periodic hedge ineffectiveness in earnings for cash flow hedges and net investment hedges that are highly effective.

Dropped from FY2019

The adoption had no material impact on our financial statements as there was no ineffectiveness recognized on our cash flow hedges or net investment hedges prior to adoption.

Dropped from FY2019

For intangible assets, we typically use a method that is a form or variation of the income approach.

Dropped from FY2019

Income approach methods start with a forecast of all of the expected future net cash flows for each asset.

Dropped from FY2019

These cash flows are then adjusted to present value by applying an appropriate discount rate that reflects the risk factors associated with the cash flow streams.

Dropped from FY2019

Determining the useful life of an intangible asset also requires judgment as different types of intangible assets will have different useful lives and certain assets may even be considered to have indefinite useful lives.

Share-Based Payments: In the first quarter of 2019, we prospectively adopted amended guidance for employee share-based payment awards.

Dropped from FY2019

This amendment provides guidance on which changes to terms or conditions of a share-based payment award require an entity to apply modification accounting.

Dropped from FY2019

Under the amended guidance, we are required to account for the effects of a modification of the fair value, the vesting conditions or the classification (as an equity instrument or a liability instrument) of the modified award from that of the original award immediately before the modification.

Dropped from FY2019

Compensation - Retirement Benefits: In the first quarter of 2019, we retrospectively adopted amended guidance 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.

Dropped from FY2019

Other components of net benefit costs are required to be presented in the statements of operations separately from the service cost component outside of operating income.

Dropped from FY2019

This amended guidance only resulted 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 the first quarter of 2019, we adopted on a modified retrospective basis amended guidance 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.

Dropped from FY2019

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.

Dropped from FY2019

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.

Dropped from FY2019

Business Combinations: In the first quarter of 2019, we prospectively adopted amended guidance that clarifies the definition of a business to assist entities in evaluating whether transactions should be accounted for as acquisitions of assets or businesses.

Dropped from FY2019

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.
