This segment also includes our 49% interest in Nadro and 39% interest in Parata.

For example, in all of our distribution centers we use Acumax® Plus, a Smithsonian award-winning technology that integrates and tracks all internal inventory-related functions such as receiving, put-away and order fulfillment.

Together, these features help ensure customers have the right products at the right time for their facilities and patients.

Competition
     In every area of healthcare distribution operations, our Distribution Solutions segment faces strong competition, both in price and service, from national, regional and local full-line, short-line and specialty wholesalers, service merchandisers, self-warehousing chains, manufacturers engaged in direct distribution and large payor organizations. In addition, this segment faces competition from various other service providers and from pharmaceutical 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. Price, quality of service, and in some cases, convenience to the customer are generally the principal competitive elements in this segment.
     Our Technology Solutions segment experiences substantial competition from many firms, including other software services firms, consulting firms, shared service vendors, certain hospitals and hospital groups, payors, 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.

Other Information about the Business
     Customers: During 2010, sales to our ten largest customers accounted for approximately 53% of our total consolidated revenues. Sales to our two largest customers, CVS Caremark Corporation (“CVS”) and Rite Aid Corporation (“Rite Aid”), accounted for approximately 15% and 12% of our total consolidated revenues. At March 31, 2010, accounts receivable from our ten largest customers were approximately 45% of total accounts receivable. Accounts receivable from CVS and Rite Aid were approximately 14% and 10% of total accounts receivable. Substantially all of these revenues and accounts receivable are included in our Distribution Solutions segment.
     Suppliers: We obtain pharmaceutical and other products from manufacturers, none of which accounted for more than approximately 8% of our purchases in 2010. 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 on the whole are good. The ten largest suppliers in 2010 accounted for approximately 46% of our purchases.
     A significant portion 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 branded 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 a material adverse impact on our gross profit margin.
     Research and Development: Our development expenditures primarily consist of our investment in software held for sale. We spent $451 million, $438 million and $420 million for development activities in 2010, 2009 and 2008 and of these amounts, we capitalized 17% for each of the last three years. Development expenditures are primarily incurred by our Technology Solutions segment. Our Technology Solutions segment’s product development efforts apply computer technology and installation methodologies to specific information processing needs of hospitals and other customers. We believe that a substantial and sustained commitment to such expenditures is important to the long-term success of this business. 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.
     Environmental Regulation: Our operations are subject to regulation 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.
     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 18, “Other 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, are presently 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 and regulations in the future. The amount of our capital expenditures for environmental compliance was not material in 2010 and is not expected to be material in the next year.

Forward-Looking Statements
     This Annual Report on Form 10-K, including “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in Item 7 of Part II of this report and the “Risk Factors” in Item 1A of Part I of this report, contains forward-looking statements within the meaning of section 27A of the Securities Act of 1933, as amended and section 21E of the Securities Exchange Act of 1934, as amended. Some of these statements can be identified by use of forward-looking words such as “believes,” “expects,” “anticipates,” “may,” “will,” “should,” “seeks,” “approximately,” “intends,” “plans” or “estimates,” or the negative of these words, or other comparable terminology. The discussion of financial trends, strategy, plans or intentions may also include forward-looking statements. Forward-looking statements involve risks and uncertainties that could cause actual results to differ materially from those projected, anticipated, or implied. 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 in Item 1A of Part I of this report under “Risk Factors.” The reader should not consider the list to be a complete statement of all potential risks and uncertainties.
     These and other risks and uncertainties are described herein and in other information contained in our publicly available SEC filings and press releases. Readers are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date such statements were first made. Except to the extent required by federal securities laws, we undertake no obligation to publicly release the result of any revisions to these forward-looking statements to reflect events or circumstances after the date hereof, or to reflect the occurrence of unanticipated events.
Item 1A.   Risk Factors
     The risks described below could have a material adverse impact on our financial position, results of operations, liquidity and cash flows. 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. 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 to our operations. The reader should not consider this list to be a complete statement of all risks and uncertainties.
We are subject to legal 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 proceedings involving antitrust, commercial, employment, environmental, intellectual property, regulatory, tort and other various claims. 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 damages. Future court decisions and legislative activity may increase the Company’s exposure to litigation and regulatory investigations. 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 remaining 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. For example, we are involved in a number of legal proceedings described in Financial Note 18, “Other Commitments and Contingent Liabilities,” to the accompanying consolidated financial statements which could have such an impact, including class actions and other legal proceedings alleging that we engaged in illegal conduct that caused average wholesale prices to rise for certain prescription drugs during specified periods.
     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. For additional information regarding certain of the legal proceedings in which we are involved, see Financial Note 18, “Other Commitments and Contingent Liabilities,” to the accompanying consolidated financial statements.
Changes in the United States healthcare environment could have a material adverse impact on our results of operations.
     Our products and services are primarily 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 has changed significantly in an effort to reduce costs. These changes include increased use of managed care, cuts in Medicare and Medicaid reimbursement levels, consolidation of pharmaceutical and medical-surgical supply distributors and the development of large, sophisticated purchasing groups.
     We expect the healthcare industry to continue to change significantly in the future. Some of these changes, such as adverse changes in government funding of healthcare services, legislation or regulations governing the privacy of patient information or the delivery or pricing of pharmaceuticals and healthcare services or mandated benefits, may cause healthcare industry participants to greatly reduce the amount of our products and services they purchase or the price they are willing to pay for our products and services.
     Changes in the healthcare industry’s or our pharmaceutical suppliers’ pricing, selling, inventory, distribution or supply policies or practices, or changes in our customer mix could also significantly reduce our revenues and net income. 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.
     Generic Pharmaceuticals: Healthcare and public policy trends indicate that the number of generic drugs will increase over the next few years as a result of the expiration of certain drug patents. In recent years, our financial results have improved from our generic drug offering programs. An increase or a decrease in the availability or changes in pricing or reimbursement of these generic drugs could have a material adverse impact on our results of operations.
     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 to its legal challenge over the branded product’s patent. To the extent we source and distribute such generic products launched “at risk,” 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.

     International Sourcing: We 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 or physical limitations that could impact continuous supply and (4) damage to our reputation due to real or perceived quality issues. Manufacturing difficulties could result in manufacturing shutdowns, product shortages and delays in product manufacturing.
     Pedigree Tracking: There have been increasing efforts by various levels of government agencies, including state boards of pharmacy and comparable government agencies, to regulate the pharmaceutical distribution system in order to prevent the introduction of counterfeit, adulterated and/or mislabeled drugs into the pharmaceutical distribution system (“pedigree tracking”). Certain states have adopted or are considering laws and regulations that are intended to protect the integrity of the pharmaceutical distribution system while other government agencies are currently evaluating their recommendations. Florida has adopted pedigree tracking requirements and California has enacted a law requiring chain of custody technology using radio frequency tagging and electronic pedigrees, which will be effective for us in July 2016. Final regulations under the federal Prescription Drug Marketing Act requiring pedigree and chain of custody tracking in certain circumstances became effective December 1, 2006. This latter regulation has been challenged in a case brought by secondary distributors. A preliminary injunction was issued by the United States District Court for the Eastern District of New York that temporarily enjoined implementation of this regulation. This injunction was affirmed by the Court of Appeals for the Second Circuit in July 2008. In December 2008, both parties agreed to delay this litigation, pending the outcome of certain U.S. congressional legislative initiatives. In addition, the U.S. Food and Drug Administration (“FDA”) 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 securing the pharmaceutical supply chain against counterfeit drugs. These standards may include any track-and-trace or authentication technologies, such as radio frequency identification devices 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 in our distribution operations. Nonetheless, these pedigree tracking laws and regulations could increase the overall regulatory burden and costs associated with our pharmaceutical distribution business, and could have a material adverse impact on our results of operations.
     Healthcare Fraud: We are subject to extensive and frequently changing local, state and federal laws and regulations relating to healthcare fraud. The federal government continues to strengthen its position and scrutiny over practices involving healthcare fraud affecting Medicare, Medicaid and other government healthcare programs. Furthermore, our relationships with pharmaceutical and medical-surgical product manufacturers and healthcare providers 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 for inducing 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 of 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 a federal health care program such as Medicare and Medicaid. Legislative provisions relating to healthcare fraud and abuse give federal enforcement personnel substantially increased funding, powers and remedies to pursue suspected fraud and abuse. Many of the regulations applicable to us, including those relating to marketing incentives, are vague or indefinite and have not been interpreted by the courts. They 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 fail to comply with applicable laws and regulations, we could 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.

     Claims Transmissions: Medical billing and collection activities are governed by numerous federal and state civil and criminal laws that pertain to companies that provide billing and collection services or that provide consulting services in connection with billing and collection activities. 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 payors 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.
     E-Prescribing: The use of our solutions by physicians for electronic prescribing, electronic routing of prescriptions to pharmacies and dispensing is governed by federal and state law. States have differing prescription format requirements, which we have programmed into our software. In addition, in November 2005, the U.S. Department of Health and Human Services (the “HHS”) announced regulations by the Centers for Medicare and Medicaid Services (“CMS”) related to “E-Prescribing and the Prescription Drug Program” (“E-Prescribing Regulations”). These E-Prescribing Regulations were mandated by the Medicare Prescription Drug, Improvement and Modernization Act of 2003. The E-Prescribing Regulations set forth standards for the transmission of electronic prescriptions. These standards are detailed and significant and cover not only transactions between prescribers and dispensers for prescriptions but also electronic eligibility, benefits inquiries, drug formulary and benefit coverage information. Our efforts to provide solutions that enable our clients to comply with these regulations could be time consuming and expensive.
     Reimbursements: Both our own profit margins and the profit margins of our customers may be adversely affected by laws and regulations reducing reimbursement rates for pharmaceuticals and/or medical treatments or services or changing the methodology by which reimbursement levels are determined. For example, the Deficit Reduction Act of 2005 (“DRA”) was intended to reduce net Medicare and Medicaid spending by approximately $11 billion over five years. Effective January 1, 2007, the DRA changed the federal upper payment limit for Medicaid reimbursement from 150% of the lowest published price for generic pharmaceuticals (which is usually the average wholesale price) to 250% of the lowest average manufacturer price (“AMP”). On July 17, 2007, CMS published a final rule implementing these provisions and clarifying, among other things, the AMP calculation methodology and the DRA provision requiring manufacturers to publicly report AMP for branded and generic pharmaceuticals. On December 19, 2007, the United States District Court for the District of Columbia issued a preliminary injunction prohibiting use of the AMP calculation in connection with Medicaid reimbursement pending resolution of a lawsuit claiming that CMS had acted unlawfully in adopting the rule. On July 15, 2008, the U.S. Congress enacted the Medicaid Improvements for Patients and Providers Acts of 2008 (“MIPPA,”) which delayed the adoption of CMS’s final rule and prevented CMS from publishing AMP data until October 1, 2009. In addition, Medicare, Medicaid and the SCHIP Extension Act of 2007 require CMS to adjust the calculation of the Medicare Part B drug average sales price (“ASP”) to an actual sales volume basis. We expect that the use of an AMP benchmark and the revised ASP calculations would result in a reduction in the Medicaid reimbursement rates to our customers for certain generic pharmaceuticals, which could indirectly impact the prices that we can charge our customers and cause corresponding declines in our profitability. There can be no assurance that the changes under the DRA would not have a material adverse impact on our results of operations.
     Interoperability Standards: There is increasing demand among customers, industry groups and government authorities that healthcare software and systems provided by various vendors be compatible with each other. This need for interoperability is leading to the development of standards by various groups. The Certification Commission for Healthcare Information Technology (“CCHIT”) has developed a set of criteria defining levels of interoperability, functionality and security for the industry, which are still being modified and refined. Various federal, state and foreign government agencies are also developing standards that could become mandatory for systems purchased by these agencies. For example, the Health Information Technology for Economic and Clinical Health (HITECH) Act portion of the American Recovery and Reinvestment Act (“ARRA”) of 2009 requires meaningful use of “certified” healthcare information technology products by healthcare providers in order to receive stimulus funds from the federal government. We may incur increased development costs and delays in delivering solutions if we need to upgrade our software and systems to be in compliance with these varying and evolving standards. In addition, these changes may lengthen our sales and implementation cycle and we may incur costs in periods prior to the corresponding recognition of revenue. Delays in achieving certification under these evolving standards may result in postponement or cancellation of our customers’ decisions to purchase our products.

     Healthcare Industry Consolidation: In recent years, the pharmaceutical suppliers have been subject to increasing consolidation. As a result, a small number of very large companies control a significant share of the market. Accordingly, we depend on fewer suppliers for our products and we are less able to negotiate price terms with the suppliers. Many healthcare organizations have consolidated to create larger healthcare enterprises with greater market power. If this consolidation trend continues, it could reduce the size of our target market and give the resulting enterprises greater bargaining power, which may lead to erosion of the prices for our products and services. In addition, when healthcare organizations combine they often consolidate infrastructure including IT systems and acquisition of our clients could erode our revenue base.
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 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 business, financial condition and results of operations.
Changes in the Canadian healthcare environment could have a material adverse impact on our results of operations.
     Similar to the United States, the Canadian healthcare industry has undergone significant changes in recent years to reduce costs. The provincial governments provide partial funding for the purchase of pharmaceuticals and independently regulate the financing and reimbursement of drugs. The Ontario government revised the drug distribution system in 2006 with the passage of the Transparent Drug System for Patients Act and has recently announced a review of that legislation in an attempt to further reduce costs. Some of the changes being considered would adversely affect the distribution of drugs, pricing for prescription drugs and reduced funding for healthcare services. Other provinces are considering similar changes, which would lower pharmaceutical pricing and service fees. Such changes could significantly reduce our Canadian revenue and operating profit.
Competition may erode our profit.
     In every area of healthcare distribution operations, our Distribution Solutions segment faces strong competition, both in price and service, from national, regional and local full-line, short-line and specialty wholesalers, service merchandisers, self-warehousing chains, manufacturers engaged in direct distribution and large payor organizations. In addition, this segment faces competition from various other service providers and from pharmaceutical 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. Price, quality of service, and in some cases, convenience to the customer are generally the principal competitive elements in this segment.
     Our Technology Solutions segment experiences substantial competition from many firms, including other software services firms, consulting firms, shared service vendors, certain hospitals and hospital groups, payors, 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 could have a material adverse impact on our results of operations.

Our Distribution Solutions segment is subject to inflation in branded pharmaceutical prices and deflation in generic pharmaceutical prices, which subjects us to risks and uncertainties.
     Inflation can be the partial basis of some of our U.S. pharmaceutical distribution business’ agreements with branded pharmaceutical manufacturers. If the frequency or rate of branded price increases slows, it could have a material adverse impact on our results of operations. In addition, we also distribute generic pharmaceuticals, which are subject to price deflation. An acceleration of the frequency or size of generic price decreases could also have a material adverse impact on our results of operations.
Substantial defaults in payment, a material reduction in purchases or the loss of a large customer or group purchasing organization could have a material adverse impact on our financial condition, results of operations and liquidity.
     In recent years, a significant portion of our revenue growth has been with a limited number of large customers. During 2010, sales to our ten largest customers accounted for approximately 53% of our total consolidated revenues. Sales to our two largest customers, CVS and Rite Aid, represented approximately 15% and 12% of our total consolidated revenues. At March 31, 2010, accounts receivable from our ten largest customers were approximately 45% of total accounts receivable. Accounts receivable from CVS and Rite Aid were approximately 14% and 10% of total accounts receivable. As a result, our sales and credit concentration is significant. We also have agreements with group purchasing organizations (“GPOs”), each of which functions as a purchasing agent on behalf of member hospitals, pharmacies and other healthcare providers. A 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 condition, results of operations and liquidity.
     We generally sell product to our 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 would reduce our revenue growth and cause a decrease in our profitability and cash flow. Further, interest rate fluctuations and changes in capital market conditions may affect our customers’ ability to obtain credit to finance their business under acceptable terms, which would reduce our revenue growth and cause a decrease in our profitability.
Our Distribution Solutions segment is dependent upon sophisticated information systems. The implementation delay, malfunction, or failure of these systems for any extended period of time could have a material adverse impact on our business.
     We rely on sophisticated information systems in our business to obtain, rapidly process, analyze and manage data to, (1) facilitate the purchase and distribution of thousands of inventory items from numerous distribution centers, (2) receive, process and ship orders and handle other product and services on a timely basis, (3) manage the accurate billing and collections for thousands of customers and (4) process payments to suppliers. If these systems are interrupted, damaged by unforeseen events or fail for any extended period of time, we could have a material adverse impact on our results of operations.
Reduced capacity in the commercial property insurance market exposes us to potential loss.
     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 an adverse impact on our results of operations.

We could become subject to liability claims that are not adequately covered by our insurance and may have to pay damages and other expenses which 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 of pharmaceuticals and medical-surgical supplies, the provision of ancillary services, the conduct of our payor businesses (which include disease management programs and our nurse triage services) and the provision of products that assist clinical decision-making and relate to patient medical histories and treatment plans. If customers 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. 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.
The failure of our healthcare technology businesses to attract and retain customers due to challenges in software product integration or to keep pace with technological advances may significantly reduce our results of operations.
     Our healthcare technology businesses, the bulk of which resides in our Technology Solutions segment, deliver enterprise-wide clinical, patient care, financial, supply chain, strategic management software solutions and pharmacy automation to hospitals, physicians, homecare providers, retail and mail order pharmacies and payors. Challenges in integrating software products could impair our ability to attract and retain customers and could have a material adverse impact on our consolidated results of operations and a disproportionate impact on the results of operations of our Technology Solutions segment.
     Future advances in the healthcare information systems industry could lead to new technologies, products or services that are competitive with the technology products and services offered by our various businesses. Such technological advances could also lower the cost of such products and services or otherwise result in competitive pricing pressure or render our products obsolete. The success of our technology businesses will depend, in part, on our ability to be responsive to technological developments, legislative initiatives, pricing pressures and changing business models. To remain competitive in the evolving healthcare information systems marketplace, our technology businesses must also develop new products on a timely basis. The failure to develop competitive products and to introduce new products on a timely basis could curtail the ability of our technology businesses to attract and retain customers and thereby could have a material adverse impact on our results of operations.
The loss of third party licenses utilized by our technology businesses may have a material adverse impact on our results of operations.
     We license the rights to use certain technologies from third-party vendors to incorporate in or complement our various healthcare technology products and solutions, which are primarily offered through our Technology Solutions segment. These licenses are generally nonexclusive, must be renewed periodically by mutual consent and may be terminated if we breach the terms of the license. As a result, we may have to discontinue, delay or reduce product shipments until we obtain equivalent technology, which could hurt our business. Our competitors may obtain the right to use any of the technology covered by these licenses and use the technology to compete directly with us. In addition, if our vendors choose to discontinue support of the licensed technology in the future, we may not be able to modify or adapt our own products.

Proprietary technology 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 technologies that are substantially equivalent or superior to our technology. 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 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 technology, obtain a license or cease selling the products that contain the infringing technology. 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 technology could have a material adverse impact on our results of operations.
System errors or failures of our products 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 software systems (“systems”) that we sell or operate are very complex. As with complex systems offered by others, our systems may contain errors, especially when first introduced. For example, our Technology Solutions segment’s business systems are intended to provide information for healthcare providers in providing patient care. Therefore, users of our systems have a greater sensitivity to errors than the general market for software products. If our software or systems lead to faulty clinical decisions or injury to patients, we could be subject to claims or litigation by our clients, clinicians or patients. In addition, such failures could damage our reputation and could negatively affect future sales.
     Failure of a client’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) computer viruses, hacking and similar disruptive problems. We attempt to mitigate these risks through various means including disaster recovery plans, separate test systems and change control and system security measures, but our precautions may not protect against all problems. 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. 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.

McKESSON CORPORATION
Regulation of our distribution businesses and regulation of our computer-related products could impose increased costs, delay the introduction of new products and negatively impact our business.
     The healthcare industry is highly regulated. We are subject to various local, state, federal, foreign and transnational laws and regulations, which include the operating and security standards of the Drug Enforcement Administration (the “DEA”), the FDA, various state boards of pharmacy, state health departments, the HHS, CMS and other comparable agencies. Certain of our subsidiaries may be required to register for permits and/or licenses with, and comply with operating and security standards of the DEA, the FDA, HHS, 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 distribution, manufacturing and sale.
     In addition, the FDA has increasingly focused on the regulation of computer products and computer-assisted products as medical devices under the federal Food, Drug and Cosmetic Act. If the FDA chooses to regulate any of our products as medical devices, 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 final FDA policy governing computer products, once issued, may increase the cost and time to market new or existing products or may prevent us from marketing our products.
     We regularly receive requests for information and occasionally subpoenas from government authorities. Although we believe that we are in compliance, in all material respects, with applicable laws and regulations, there can be no assurance that a regulatory agency or tribunal would not reach a different conclusion concerning the compliance of our operations with applicable laws and regulations. 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. Any noncompliance by us with applicable laws and regulations or the failure to maintain, renew or obtain necessary permits and licenses could have a material adverse impact on our results of operations.
Regulations relating to confidentiality of sensitive personal information and to format and data content standards could depress the demand for our products and impose significant product redesign costs and unforeseen liabilities on us.
     State, federal and foreign laws regulate the confidentiality of sensitive personal information and the circumstances under which such information may be released. These regulations govern the disclosure and use of confidential personal and patient medical record information and require the users of such information to implement specified security measures. Regulations currently in place, including regulations governing electronic health data transmissions, continue to evolve and are often unclear and difficult to apply. Although our systems are being updated and modified to comply with the current requirements of state and foreign laws and the Federal Health Insurance Portability and Accountability Act of 1996 (“HIPAA”) and the HITECH Act, evolving laws and regulations in this area could restrict the ability of our customers to obtain, use or disseminate patient information or could require us to incur significant additional costs to re-design our products in a timely manner, either of which could have a material adverse impact on our results of operations. In addition, in February 2010, certain provisions of the federal security and privacy standards have been extended to us in our capacity as a business associate of our payor and provider customers. Furthermore, failure to maintain confidentiality of sensitive personal information in accordance with the applicable regulatory requirements could expose us to breach of contract claims, fines and penalties, costs for remediation and harm to our reputation.

The length of our sales and implementation cycles for our Technology Solutions segment could have a material adverse impact on our future results of operations.
     Many of the solutions offered by our Technology Solutions segment have long sales and implementation cycles, which could range from a few months to two years or more from initial contact with the customer to completion of implementation. How and when to implement, replace, or expand an information system, or modify or add business processes, are major decisions for healthcare organizations. Many of the solutions we provide typically require significant capital expenditures and time commitments by the customer. Recent legislation that provides incentives to purchase health information systems imposes strict conditions on these incentives, including the requirement that purchased systems must comply with applicable federally-endorsed standards. To the extent these standards are narrowly construed or delayed in publication, our customers may delay or cancel their purchase decisions. Any decision by our customers to delay or cancel implementation could have a material adverse impact on our results of operations. Furthermore, delays or failures to meet milestones established in our agreements may result in a breach of contract, termination of the agreement, damages and/or penalties as well as a reduction in our margins or a delay in our ability to recognize revenue.
We may be required to record a significant charge to earnings if our goodwill or intangible assets become impaired.
     We are required under U. S. generally 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 assets for impairment when events or changes in circumstances 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 assets may not be recoverable include slower growth rates and the loss of a significant customer. 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 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 and intangible assets. Any changes in key assumptions, including failure to meet business plans, a further deterioration in the market or other unanticipated events and circumstances, may affect the accuracy or validity of such estimates and could potentially result in an impairment charge.
Our foreign operations may subject us to a number of operating, economic, political and regulatory risks that may have a material adverse impact on our financial condition and results of operations.
     We have operations based in foreign countries, including Canada, the United Kingdom, other European countries, Asia Pacific and Israel and we have a large investment in Mexico. In the future, we look to continue to grow our foreign operations both organically and through acquisitions and investments; however, increasing our foreign operations carries additional risks. Operations outside of the United States may be affected by changes in trade protection laws, policies, measures and other regulatory requirements affecting trade and investment; unexpected changes in regulatory requirements for software, social, political, labor or economic conditions in a specific country or region; import/export regulations in both the United States and foreign countries and difficulties in staffing and managing foreign operations. Political changes 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. Additionally, foreign operations expose us to foreign currency fluctuations that could adversely impact our results of operations based on the movements of the applicable foreign currency exchange rates in relation to the U.S. dollar.
     Foreign operations are also subject to risks of violations of laws prohibiting improper payments and bribery, including the U.S. Foreign Corrupt Practices Act and similar regulations in foreign jurisdictions. Failure to comply with these laws could subject us to civil and criminal penalties that could have a material adverse impact on our financial condition and results of operations.

Tax legislation initiatives or challenges to our tax positions could have a material adverse impact on our results of operations.
     We are a large multinational corporation with operations in the United States and international jurisdictions. As such, we are subject to the tax laws and regulations of the United States federal, state and local governments and of many international jurisdictions. From time-to-time, various legislative initiatives may be proposed that could adversely affect our tax positions. There can be no assurance that our effective tax rate will not be adversely affected by these initiatives. In addition, United States federal, state and local, as well as international, tax laws and regulations are extremely complex and subject to varying interpretations. 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.
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 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; challenges in retaining the customers of the combined businesses and a potential material adverse impact on operating results. In addition, we may potentially require additional financing in order to fund future acquisitions, which may or may not be attainable. 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.
Continued 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, decreased liquidity and increased costs in the commercial paper market and the reduced market for securitizations, may adversely affect the availability and cost of credit already arranged and the availability, terms and cost of credit in the future, including any arrangements to renew or replace our current credit or financing arrangements. Although we believe that our operating cash flow, financial assets, current access to capital and credit markets, including our existing credit and sales facilities, will give us the ability to meet our financing needs for the foreseeable future, there can be no assurance that continued or increased volatility and disruption in the global capital and credit markets will not impair our liquidity or increase our costs of borrowing.
     Our $1.1 billion accounts receivable sales facility is generally renewed annually and will expire in mid-May 2010. Although we did not use this facility in 2010, we have historically used it to fund working capital requirements, as needed. We anticipate renewing this facility before its expiration. If our use of the current accounts receivable sales facility is characterized as a secured borrowing rather than a sale for U.S. GAAP purposes under accounting pronouncements that will become effective for us in 2011, we may be required to consider the funds obtained by us under this facility and the related liens in the covenant compliance calculations for certain of our other financing arrangements. Although we believe we will be able to renew this facility, there is no assurance that we will be able to do so.
     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 material adverse impact on our results of operations and cash flow.

Changes in accounting standards issued by the Financial Accounting Standards Board (“FASB”) or other standard-setting bodies may adversely affect our financial statements.
     Our financial statements are subject to the application of U.S. GAAP, which is periodically revised and/or expanded. Accordingly, 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 could change the current accounting treatment that we apply to our consolidated financial statements and that such changes could have a material adverse impact on our results of operations and financial condition.

The warehouses are typically owned or leased on a long-term basis. We consider our operating properties to be in satisfactory condition and adequate to meet our needs for the next several years without making capital expenditures materially higher than historical levels.

     In April 2008, the Board approved a plan to repurchase up to $1.0 billion of the Company’s common stock of which $531 million remained available for future repurchases as of March 31, 2010. During the fourth quarter of 2010, the Company did not repurchase any shares of common stock. During 2010, the Company repurchased approximately 8 million shares of its common stock at an average price of $41.47 for $299 million. In April 2010, the Board authorized the repurchase of up to an additional $1.0 billion of the Company’s common stock. Stock repurchases may be made from time-to-time in open market transactions, privately negotiated transactions, through accelerated share repurchase programs, or by any combination of such methods. The timing of any repurchases and the actual number of shares repurchased will depend on a variety of factors, including our stock price, corporate and regulatory requirements, restrictions under our debt obligations and other market and economic conditions.

FINANCIAL REVIEW
Item 7.   Management’s Discussion and Analysis of Financial Condition and Results of Operations
GENERAL
     Management’s discussion and analysis of financial condition and results of operations, referred to as the Financial Review, is intended to assist the reader in the understanding and assessment of significant changes and trends related to the results of operations and financial position of the Company together with its subsidiaries. This discussion and analysis should be read in conjunction with the consolidated financial statements and accompanying financial notes in Item 8 of Part II of this Annual Report on Form 10-K. The Company’s fiscal year begins on April 1 and ends on March 31. Unless otherwise noted, all references in this document to a particular year shall mean the Company’s fiscal year.
     Certain statements in this report constitute forward-looking statements. See Item 1 – Business – Forward-Looking Statements in Part I of this Annual Report on Form 10-K for additional factors relating to these statements; also see Item 1A – Risk Factors in Part I of this Annual Report on Form 10-K for a list of certain risk factors applicable to our business, financial condition and results of operations.
     We conduct our business through two operating segments: Distribution Solutions and Technology Solutions. See Financial Note 21, “Segments of Business,” to the accompanying consolidated financial statements for a description of these segments.
RESULTS OF OPERATIONS

     Revenues increased 2% to $108.7 billion in 2010 and 5% to $106.6 billion in 2009. The increase in revenues primarily reflects market growth in our Distribution Solutions segment, which accounted for approximately 97% of our consolidated revenues. To a lesser extent, revenues for 2010 were also affected by an increase in demand related to the flu season. These increases were partially offset by the loss of several customers in late 2009. Revenues for 2009 were increased by our acquisitions of Oncology Therapeutics Network (“OTN”) in October 2007 and McQueary Brothers Drug Company (“McQueary Brothers”) in May 2008.
     Income from continuing operations before income taxes increased 75% to $1.9 billion in 2010 and decreased 27% to $1.1 billion in 2009. The increase in 2010 was due to improved gross profit, lower operating expenses compared to 2009, which included the $493 million Average Wholesale Price (“AWP”) litigation charge discussed below, and increases in other income, partially offset by higher interest expense. The decrease in income from continuing operations before income taxes in 2009 was due to higher operating expenses, primarily caused by the AWP litigation charge, and due to lower other income, partially offset by improved gross profit.

     Gross profit increased 6% to $5.7 billion and 7% to $5.4 billion in 2010 and 2009. As a percentage of revenues, gross profit increased 18 basis points (“bp”) to 5.22% and 11 bp to 5.04% in 2010 and 2009. Gross profit margin increased in 2010 primarily reflecting an improved mix of higher margin revenues in both our Distribution Solutions and Technology Solutions segments. The increase in our 2009 gross profit margin was primarily due to an improvement in our Distribution Solutions segment margin, partially offset by a decline in our Technology Solutions segment margin.
     Operating expenses were $3.7 billion, $4.2 billion and $3.5 billion in 2010, 2009 and 2008. Operating expenses for 2010 decreased compared to 2009, which included the AWP litigation charge as further discussed under the caption “Operating Expenses” in this Financial Review. Excluding the AWP litigation charge, operating expenses for 2010 approximated the same period a year ago primarily due to lower Profit Sharing Investment Plan (“PSIP”) expense as more fully described under the caption “Operating Expenses” in this Financial Review, cost containment efforts, the sale of two businesses during the first and third quarters in 2009 and the reversal of a previously established litigation accrual. These decreases were partially offset by an increase in expenses associated with employee compensation and benefit costs, our 2009 business acquisitions and other business initiatives. Operating expenses for 2009 increased primarily due to additional expenses incurred to support our sales growth, expenses associated with our business acquisitions and higher employee compensation. As noted above, operating expenses for 2009 included a pre-tax charge of $493 million for the AWP litigation charge.
     In 2010, other income, net includes a $17 million pre-tax gain ($14 million after-tax) from the sale of our 50% equity interest in McKesson Logistics Solutions L.L.C. (“MLS”). In 2009, other income, net includes a pre-tax impairment charge of $63 million ($60 million after-tax) on two equity-held investments and a pre-tax gain of $24 million ($14 million after-tax) from the sale of an equity-held investment. Over the last two years, other income, net was negatively affected by a decrease in interest income due to lower interest rates and in 2009 was affected by a lower average cash and cash equivalents balance.
     Interest expense increased 30% to $187 million in 2010 and 1% to $144 million in 2009. Interest expense increased in 2010 compared to the prior year primarily due to our issuance of $700 million of long-term notes in February 2009. Interest expense for 2009 reflects the repayment of $150 million of long-term debt during the fourth quarter of 2008 and the issuance of $700 million of long-term debt during the fourth quarter of 2009.
     Our reported income tax rates were 32.2%, 22.7% and 32.1% in 2010, 2009 and 2008. In 2009, current income tax expense included $111 million of net income tax benefits for discrete items of which, $87 million represents a non-cash benefit. These benefits primarily relate to the recognition of previously unrecognized tax benefits and related accrued interest. The recognition of these discrete items is primarily due to the lapsing of the statutes of limitations.
     Net income was $1,263 million, $823 million and $990 million in 2010, 2009 and 2008 and diluted earnings per common share were $4.62, $2.95 and $3.32, which were favorably affected by decreases in our weighted average shares outstanding due to the cumulative effect of share repurchases from 2008 to 2010.

     Total revenues increased 2% to $108.7 billion in 2010 and 5% to $106.6 billion in 2009. The growth in revenues was primarily driven by our Distribution Solutions segment, which accounted for approximately 97% of revenues.
     Direct distribution and services revenues increased in 2010 compared to 2009 primarily due to a shift of revenues from sales to customers’ warehouses to direct store delivery and market growth, which includes price increases and increased volume from new and existing customers, offset in part by the greater sales of lower priced generic drugs. This increase was partially offset by the loss of several customers in late 2009. Direct distribution and services revenues increased in 2009 compared to 2008 primarily reflecting market growth, our acquisitions of OTN in October 2007 and McQueary Brothers in May 2008 and a shift of revenues from sales to customers’ warehouses to direct store delivery.
     Sales to customers’ warehouses for 2010 decreased compared to prior year primarily due to a shift of revenues to direct store delivery, reduced revenues associated with a large customer and the loss of a large customer in mid-2009, partially offset by expanded business with existing customers. Sales to customers’ warehouses decreased in 2009 compared to 2008 primarily reflecting a customer’s loss of business, the loss of a large customer and reduced revenues associated with the consolidation of certain customers. Additionally, 2009 revenues were also impacted by a shift to direct store delivery. These decreases were partially offset by expanded business with existing customers.
     Sales to retail customers’ warehouses represent large volume sales of pharmaceuticals primarily to a limited number of large self-warehousing retail chain customers whereby we order bulk product from the manufacturer, receive and process the product through our central distribution facility and subsequently deliver the bulk product (generally in the same form as received from the manufacturer) directly to our customers’ warehouses. This distribution method is typically not marketed or sold by the Company as a stand-alone service; rather, it is offered as an additional distribution method for our large retail chain customers that have an internal self-warehousing distribution network. Sales to customers’ warehouses provide a benefit to these customers because they can utilize the Company as one source for both their direct-to-store business and their warehouse business. We generally have significantly lower gross profit margins on sales to customers’ warehouses as we pass much of the efficiency of this low cost-to-serve model on to the customer. These sales do, however, contribute to our gross profit dollars.

     The customer mix of our U.S. pharmaceutical distribution revenues was as follows:
                         
    2010   2009   2008
 
Direct Sales

    12 %     13 %     13 %

Total
    100 %     100 %     100 %
 
     In 2010, the percentage of total direct and warehouse revenue attributed to the Company’s retail chain customers compared to our other customer groups increased slightly from the same period a year ago, while it declined in 2009. In 2009, this decline resulted in a positive impact on the Company’s gross profit margin. As previously described, a limited number of our large retail chain customers purchase products through both the Company’s direct and warehouse distribution methods, the latter of which generally has a significantly lower gross profit margin due to the low cost-to-serve model. When evaluating and pricing customer contracts, we do so based on our assessment of total customer profitability. As a result, we do not evaluate the Company’s performance or allocate resources based on sales to customers’ warehouses or gross profit associated with such sales.
     Canadian pharmaceutical distribution and services revenues for 2010 increased on a constant currency basis by 7% from prior year primarily due to market growth, which includes price increases and increased volume from new and existing customers and a favorable foreign exchange rate of 3%. Canadian pharmaceutical distribution and services revenues for 2009 increased slightly primarily reflecting market growth, which was almost fully offset by 9% unfavorable foreign exchange rates and the loss of a customer.
     Medical-Surgical distribution and services revenues increased in 2010 compared to 2009 reflecting an increase in demand related to the flu season, acquisitions and increased volume from new and existing customers. Medical-Surgical distribution and services revenues increased for 2009 from prior year primarily reflecting market growth and acquisitions. In addition, revenues in 2008 were impacted by the discontinuance of the distribution of a product line. Revenues associated with this product line are now recorded by our U.S. pharmaceutical distribution and services business.
     Technology Solutions revenues increased in 2010 compared to prior year due to higher services revenues primarily caused by increases in outsourcing revenues for claims processing and other services and software maintenance reflecting the segment’s expanded customer base. These increases were partially offset by a shift to products that have higher revenue deferral rates and lower hardware sales. Technology Solutions revenues increased in 2009 primarily due to increased services revenues primarily reflecting the segment’s expanded customer base and outsourcing revenues for claims processing. These increases were partially offset by unfavorable foreign exchange rates and a decrease in software revenues, particularly in the hospital and physician office customer channels.

     Gross profit increased 6% to $5.7 billion in 2010 and 7% to $5.4 billion in 2009. As a percentage of revenues, gross profit increased by 18 bp in 2010 and 11 bp in 2009. Gross profit margin increased in 2010 primarily due to an improved mix of higher margin revenues in both of our operating segments. Our Distribution Solutions segment margin increased primarily due to flu-related demand. Our Technology Solutions segment margin improved reflecting a change in revenue mix. In 2009, the increase in our Distribution Solutions gross profit margin was partially offset by a decline in our Technology Solutions segment reflecting a change in revenue mix and the recognition of $21 million of disease management deferred revenues in 2008 for which associated expenses were previously recognized as incurred.
     In 2010, our Distribution Solutions segment’s gross profit margin increased compared to 2009 primarily due to the impact of the H1N1 flu virus, which helped drive an improved mix of higher margin revenues stemming from increased flu-related demand across our distribution businesses. Gross profit margin was also favorably affected by a higher buy side margin, which primarily reflects compensation from branded pharmaceutical manufacturers, and increased sales of higher margin generic drugs. These benefits were partially offset by a decline in sell margin. Our last-in, first-out (“LIFO”) net inventory expense was $8 million for 2010 and 2009.
     In 2009, our Distribution Solutions segment’s gross profit margin increased compared to 2008. Gross profit margin was impacted by the benefit of increased sales of generic drugs with higher margins; higher buy side margins and an increase associated with a lower proportion of revenues within the segment attributed to sales to customers’ warehouses, which generally have lower gross profit margins relative to other revenues within the segment. These increases were partially offset by a modest decline in sell margin during the latter part of the year and LIFO net inventory credits ($8 million LIFO net expense in 2009 compared to a $14 million LIFO net credit in 2008).
     Our Distribution Solutions segment 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 practice in the Distribution Solutions’ distribution businesses is to pass on to customers published price changes from suppliers. Manufacturers generally provide us with price protection, which limits price-related inventory losses. Price declines on many generic pharmaceutical products in this segment over the last few years have moderated the effects of inflation in other product categories, which resulted in minimal overall price changes in those years. Additional information regarding our LIFO accounting is included under the caption “Critical Accounting Policies and Estimates,” included in this Financial Review.
     For each of the last three years, the Company’s sales to customers’ warehouses represented 5% or less of the segment’s total gross profit dollars. In 2010, the percentage of total direct and warehouse revenue attributed to our retail chain customers compared to our other customer groups increased slightly from the same period a year ago, while it declined in 2009. In 2009, this decline resulted in a positive impact on the Company’s gross profit margin.

     In 2010, our Technology Solutions segment’s gross profit margin was favorably affected by a change in revenue mix, partially offset by a higher software revenue deferral rate.

     Operating expenses decreased 12% to $3.7 billion in 2010 and increased 18% to $4.2 billion in 2009. Operating expenses for 2010 decreased compared to 2009, which included the AWP litigation charge as more fully described below. Excluding the AWP litigation charge, operating expenses for 2010 approximated the same period a year ago primarily due to lower PSIP expense as more fully described below, cost containment efforts, the sale of two businesses during the first and third quarters in 2009 and the reversal of a previously established litigation accrual. These decreases were partially offset by an increase in expenses associated with employee compensation and benefit costs, our 2009 business acquisitions and other business initiatives.
     Excluding the AWP litigation charge, operating expenses for 2009 increased primarily due to additional expenses incurred to support our sales growth, expenses associated with our business acquisitions and higher employee compensation.
     The McKesson Corporation PSIP is a member of the settlement class in the Consolidated Securities Litigation Action. On April 27, 2009, the court issued an order approving the distribution of the settlement funds. On October 9, 2009, the PSIP received approximately $119 million of the Consolidated Securities Litigation Action proceeds. Approximately $42 million of the proceeds were attributable to the allocated shares of McKesson common stock owned by the PSIP participants during the Consolidated Securities Litigation Action class-holding period and were allocated to the respective participants on that basis in the third quarter of 2010. Approximately $77 million of the proceeds were attributable to the unallocated shares (the “Unallocated Proceeds”) of McKesson common stock owned by the PSIP in an employee stock ownership plan (“ESOP”) suspense account. In accordance with the plan terms, the PSIP distributed all of the Unallocated Proceeds to current PSIP participants after the close of the plan year in April 2010. The receipt of the Unallocated Proceeds by the PSIP was reimbursement for the loss in value of the Company’s common stock held by the PSIP in its ESOP suspense account during the Consolidated Securities Litigation Action class-holding period and was not a contribution made by the Company to the PSIP or ESOP. Accordingly, there were no accounting consequences to the Company’s financial statements relating to the receipt of the Unallocated Proceeds by the PSIP.

     The Company’s PSIP expense for the full year is negligible, as the Company did not make additional contributions to the PSIP or ESOP. As a result, our compensation expense in 2010 was lower than 2009. During 2009 and 2008, PSIP expense was $53 million and $13 million. The expense for 2008 was lower than 2009 due to the utilization of lower cost basis shares from the ESOP to fund our matching contributions. The expense for 2011 is expected to be approximately $58 million.

FINANCIAL REVIEW (Continued)
     On a segment basis, Distribution Solutions’ operating expenses decreased in 2010 and increased in 2009 primarily due to the $493 million AWP litigation charge in 2009. Excluding the AWP litigation charge, operating expenses and operating expenses as a percentage of revenues decreased in 2010 primarily due to the sale of two businesses during the first and third quarters of 2009, lower PSIP expense in 2010 and our continued focus on cost containment, partially offset by an increase in expenses associated with our 2009 business acquisitions.
     Excluding the AWP litigation charge, operating expenses in 2009 increased primarily due to business acquisitions and additional costs incurred to support our sales volume growth. Operating expenses as a percentage of revenues increased in 2009 primarily due to the AWP litigation charge as well as additional costs incurred to support our sales volume growth.
     As discussed in Financial Note 18, “Other Commitments and Contingent Liabilities,” in 2009 we reached an agreement to settle all private party claims relating to First DataBank, Inc.’s published drug reimbursement benchmarks for $350 million. We also recorded an accrual for pending and expected AWP-related claims by public payors, which is currently estimated to be $143 million. The combination of the AWP settlement for all private party claims and the decision by us to establish an estimated accrual for the pending and expected AWP-related claims by public payors resulted in a pre-tax, non-cash charge of $493 million in the third quarter of 2009.
     Technology Solutions segment’s operating expenses decreased over the past two years. Operating expenses and operating expenses as a percentage of revenues for 2010 benefited from lower PSIP expense, cost containment efforts and reduction in workforce plans implemented in 2009, partially offset by our continued investment in research and development activities. Operating expenses for 2009 decreased primarily due to cost containment efforts and a decrease in bad debt expense, partially offset by an increase in net research and development expenses and additional costs for business acquisitions. Operating expenses as a percentage of revenues for this segment decreased for 2009 primarily reflecting the segment’s cost containment efforts and a more favorable business mix.
     Corporate expenses have increased over the last two years. Corporate expenses for 2010 increased primarily due to higher compensation and benefits costs, other business initiatives and legal settlement charges, partially offset by the reversal of a previously established litigation accrual. Corporate expenses increased in 2009 compared to 2008 primarily reflecting an increase in accounts receivable sales facility fees, compensation expense and additional costs incurred to support various initiatives.

     In 2010, other income, net includes a $17 million pre-tax gain ($14 million after-tax) from the sale of our 50% equity interest in MLS. The gain on sale of our investment in MLS was recorded within our Distribution Solutions segment. The increase in other income, net was partially offset by a decrease in interest income due to lower interest rates in 2010. Interest income, which is primarily recorded in Corporate, was $16 million, $31 million and $89 million in 2010, 2009 and 2008.
     In 2009, other income, net included a pre-tax impairment charge of $63 million ($60 million after-tax) on two equity-held investments (as further described below) and a pre-tax gain of $24 million ($14 million after-tax) from the sale of our 42% equity interest in Verispan, LLC (“Verispan”). The impairment charge and the gain on sale of our investment in Verispan were both recorded within our Distribution Solutions segment. Excluding these items, other income, net decreased primarily due to a decrease in interest income from lower average cash and cash equivalents balances and interest rates.

FINANCIAL REVIEW (Continued)
     We evaluate our investments for impairment when events or changes in circumstances indicate that the carrying values of such investment may have experienced an other-than-temporary decline in value. During the fourth quarter of 2009, we determined that the fair value of our interest in Parata was lower than its carrying value and that such impairment was other-than-temporary. Fair value was determined using a discounted cash flow analysis based on estimated future results and market capitalization rates. We determined the impairment was other-than-temporary based on our assessment of all relevant factors including deterioration in the investee’s financial condition and weak market conditions. As a result, we recorded a pre-tax impairment of $58 million ($55 million after-tax) on this investment which is recorded within other income, net in the consolidated statements of operations. Our investment in Parata is accounted for under the equity method of accounting within our Distribution Solutions segment.
     During the fourth quarter of 2009, we also recorded a pre-tax impairment of $5 million ($5 million after-tax) on another equity-held investment within our Distribution Solutions segment.

     In 2010, operating profit margin for our Distribution Solutions segment increased primarily due to a higher gross profit margin, lower operating expenses as a percentage of revenues and the gain on sale of the segment’s 50% equity investment in MLS. Operating expenses improved due to the sale of two businesses during the first and third quarters of 2009 and lower PSIP expense, partially offset by an increase in expenses associated with our business acquisitions. Results for 2009 included the $493 million AWP litigation charge, $63 million of pre-tax charges to write-down two equity-held investments and a $24 million pre-tax gain on the sale of the segment’s 42% equity investment in Verispan.
     In 2009, operating profit margin in our Distribution Solutions segment decreased compared to 2008 primarily due to an increase in operating expenses as a percentage of revenues as a result of the AWP litigation charge and a decrease in other income, partially offset by a higher gross profit margin.

     In 2010, operating profit margin in our Technology Solutions segment increased compared to 2009 primarily due to lower operating expenses as a percentage of revenues and an improvement in gross profit margin.
     In 2009, operating profit margin in our Technology Solutions segment increased compared to 2008 primarily due to a decrease in operating expenses as a percentage of revenues, partially offset by a decrease in gross profit margin. Operating profit margin for this segment for the past two years has benefited from cost containment efforts and a more favorable revenue mix.
     Corporate expenses, net of other income increased in 2010 compared to 2009 primarily due to an increase in operating expenses and a decrease in interest income. Corporate expenses, net of other income, increased in 2009 compared to 2008 primarily due to a decrease in interest income and an increase in operating expenses.
     Litigation Credit, Net: In 2010 and 2008 we recorded net credits of $20 million and $5 million relating to settlements for the securities litigation.
     Interest Expense: Interest expense increased in 2010 compared to the prior year primarily due to our issuance of $700 million of long-term notes in February 2009. Interest expense increased slightly in 2009 compared to the prior year, which reflects the repayment of $150 million of long-term debt during the fourth quarter of 2008 and the issuance of $700 million of long-term debt during the fourth quarter of 2009. Refer to our discussion under the caption “Credit Resources” within this Financial Review for additional information regarding our financing activities.
     Income Taxes: Our reported tax rates were 32.2%, 22.7% and 32.1% in 2010, 2009 and 2008. In addition to the items noted below, fluctuations in our reported tax rate are primarily due to changes within our business mix, including varying proportions of income attributable to foreign countries that have lower income tax rates.
     In 2009, we recorded a $182 million income tax benefit for the AWP litigation accrual. The tax benefit could change in the future depending on the resolution of the pending and expected claims.
     In 2009, current income tax expense included $111 million of net income tax benefits for discrete items of which $87 million represents a non-cash benefit. These benefits primarily relate to the recognition of previously unrecognized tax benefits and related accrued interest. The recognition of these discrete items was primarily due to the lapsing of the statutes of limitations.
     In 2008, the U.S. Internal Revenue Service (“IRS”) began its examination of our fiscal years 2003 through 2006. In 2009 and 2010, we received assessments from the Canada Revenue Agency (“CRA”) for a total of $62 million related to transfer pricing for 2003, 2004 and 2005. We paid the CRA assessments to stop the accrual of interest. We have appealed the assessment for 2003 and have filed a notice of objection for 2004 and 2005. We believe we have adequately provided for any potential adverse results. In nearly all jurisdictions, the tax years prior to 2003 are no longer subject to examination. We believe that we have made adequate provision for all remaining income tax uncertainties.
     In 2008, the IRS completed an examination of our consolidated income tax returns for 2000 to 2002 resulting in a signed Revenue Agent Report (“RAR”), which was subsequently approved by the Joint Committee on Taxation. The IRS and the Company agreed to certain adjustments, primarily related to transfer pricing and income tax credits. As a result of the approved RAR, we recognized approximately $25 million of net federal and state income tax benefits in 2008.
     Discontinued Operations: No charges for discontinued operations were incurred during 2010 and 2009. In 2008, discontinued operations included $1 million from the Company’s Acute Care business, which was sold in 2007.

FINANCIAL REVIEW (Continued)
     Net Income: Net income was $1,263 million, $823 million and $990 million in 2010, 2009 and 2008 and diluted earnings per common share were $4.62, $2.95 and $3.32. The net income and diluted earnings per common share for 2009 included a pre-tax charge of $493 million ($311 million after-tax) for the AWP litigation as discussed in further detail under the caption “Operating Expenses” in this Financial Review.
     Weighted Average Diluted Common Shares Outstanding: Diluted earnings per common share was calculated based on a weighted average number of shares outstanding of 273 million, 279 million and 298 million for 2010, 2009 and 2008. The decrease in the number of weighted average diluted common shares outstanding over the past two years primarily reflects a decrease in the number of shares outstanding as a result of stock repurchased, partially offset by exercise of share-based awards.
International Operations
     International operations accounted for 8.6%, 7.9% and 8.2% of 2010, 2009 and 2008 consolidated revenues. International 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. Additional information regarding our international operations is also included in Financial Note 21, “Segments of Business,” to the accompanying consolidated financial statements.
Business Combinations and Investments
     In 2009, we made the following acquisition:
     On May 21, 2008, we acquired McQueary Brothers of Springfield, Missouri for approximately $190 million. McQueary Brothers is a regional distributor of pharmaceutical, health and beauty products to independent and regional chain pharmacies in the Midwestern U.S. This acquisition expanded our existing U.S. pharmaceutical distribution business. The acquisition was funded with cash on hand. During the first quarter of 2010, the acquisition accounting was completed. Approximately $126 million of the purchase price allocation has been assigned to goodwill, which primarily reflects the expected future benefits from synergies to be realized upon integrating the business. Included in the purchase price allocation are acquired identifiable intangibles of $61 million representing a customer relationship with a useful life of 7 years, a trade name of $2 million with a useful life of less than one year and a not-to-compete agreement of $4 million with a useful life of 4 years. Financial results for McQueary Brothers have been included within our Distribution Solutions segment since the date of acquisition.
     In 2008, we made the following acquisition:
     On October 29, 2007, we acquired all of the outstanding shares of OTN of San Francisco, California for approximately $519 million, including the assumption of debt and net of $31 million of cash and cash equivalents acquired from OTN. During the third quarter of 2009, the acquisition accounting was completed. OTN is a U.S. distributor of specialty pharmaceuticals. The acquisition of OTN expanded our existing specialty pharmaceutical distribution business. The acquisition was funded with cash on hand. Financial results for OTN are included within our Distribution Solutions segment since the date of acquisition. Approximately $240 million of the purchase price allocation has been assigned to goodwill, which primarily reflects the expected future benefits from synergies upon integrating the business. Included in the purchase price allocation are acquired identifiable intangibles of $115 million representing customer relationships with a weighted-average life of 9 years, developed technology of $3 million with a weighted-average life of 4 years and trademarks and trade names of $10 million with a weighted-average life of 5 years.

     During the last three years, we also completed a number of other smaller acquisitions and investments within both of our operating segments. Financial results for our business acquisitions have been included in our consolidated financial statements since their respective acquisition dates. Purchase prices for our business acquisitions have been allocated based on estimated fair values at the date of acquisition and for certain recent acquisitions may be subject to change as we continue to evaluate and implement various restructuring initiatives. Goodwill recognized for our business acquisitions is generally not expected to be deductible for tax purposes. Pro forma results of operations for our business acquisitions have not been presented because the effects were not material to the consolidated financial statements on either an individual or an aggregate basis. Refer to Financial Note 2, “Business Combinations and Investments,” to the consolidated financial statements appearing in this Annual Report on Form 10-K for further discussions regarding our acquisitions and investing activities.
2011 Outlook
     Information regarding the Company’s 2011 outlook is contained in our Form 8-K dated May 3, 2010. This Form 8-K should be read in conjunction with the sections Item 1 — Business — Forward-looking Statements and Item 1A — Risk Factors in Part 1 of this Annual Report on Form 10-K.
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 determining the appropriate allowance for doubtful accounts, which includes portfolio and specific reserves, the Company reviews accounts receivable aging, industry trends, customer financial strength, credit standing, historical write-off trends and payment history 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. At March 31, 2010, revenues and accounts receivable from our ten largest customers accounted for approximately 53% of consolidated revenues and 45% of accounts receivable. At March 31, 2010, revenues and accounts receivable from our two largest customers, CVS and Rite Aid, represented approximately 15% and 12% of total consolidated revenues and 14% and 10% of accounts receivable. As a result, our sales and credit concentration is significant. A default in payments, a material reduction in purchases from these, or any other large customer or the loss of a large customer could have a material adverse impact on our financial condition, 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 2010 are appropriate and consistent with historical methodologies employed. At this time, we are not aware of any internal process or customer issues that might lead to a significant increase in the foreseeable future in our allowance for doubtful accounts as a percentage of net revenue.
     At March 31, 2010, trade and notes receivables were $7,375 million prior to allowances of $131 million. In 2010, 2009 and 2008 our provision for bad debts was $17 million, $29 million and $41 million. At March 31, 2010 and 2009, the allowance as a percentage of trade and notes receivables was 1.8% and 2.2%. An increase or decrease of 0.1% in the 2010 allowance as a percentage of trade and notes receivables would result in an increase or decrease in the provision on receivables of approximately $7 million. Additional information concerning our allowance for doubtful accounts may be found in Schedule II included in this Annual Report on Form 10-K.
     Inventories: We report inventories at the lower of cost or market (“LCM”). Inventories for our Distribution Solutions segment consist of merchandise held for resale. For our Distribution Solutions segment, the majority of the cost of domestic inventories is determined using the LIFO method and the cost of Canadian inventories is determined using the first-in, first-out (“FIFO”) method. Technology Solutions segment inventories consist of computer hardware with cost determined by the standard cost method. Rebates, fees, cash discounts, allowances, chargebacks and other incentives received from vendors are generally accounted for as a reduction in the cost of inventory and are recognized when the inventory is sold. Total inventories were $9.4 billion and $8.5 billion at March 31, 2010 and 2009.
     The LIFO method was used to value approximately 87% and 88% of our inventories at March 31, 2010 and 2009. At March 31, 2010 and 2009, our LIFO reserves, net of LCM adjustments, were $93 million and $85 million. LIFO reserves include both pharmaceutical and non-pharmaceutical products. In 2010 and 2009, we recognized net LIFO expense of $8 million and in 2008, net LIFO credits of $14 million within our consolidated statements of operations. In 2010, our $8 million net LIFO expense related to our non-pharmaceutical products. A LIFO expense is recognized when the net effect of price increases on branded pharmaceuticals and non-pharmaceutical products held in inventory exceeds the impact of price declines and shifts towards generic pharmaceuticals, including the effect of branded pharmaceutical products that have lost market exclusivity. A LIFO credit is recognized when the impact of price declines and shifts towards generic pharmaceuticals exceeds the impact of price increases on branded pharmaceuticals and non-pharmaceutical products held in inventory.
     We believe that the FIFO 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 inventory as valued under FIFO. Primarily due to continued deflation in generic pharmaceutical inventories, pharmaceutical inventories at LIFO were $112 million and $107 million higher than FIFO as of March 31, 2010 and 2009. As a result, in 2010 and 2009, we recorded LCM charges of $5 million and $64 million within our consolidated statements of operations to adjust our LIFO inventories to market. As deflation in generic pharmaceuticals continues, we anticipate that LIFO credits from the valuation of our pharmaceutical products will be fully offset by LCM reserves.
     In determining whether inventory valuation issues exist, 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 provide reserves for excess and obsolete inventory, if indicated, as a result of these reviews. These factors could make our estimates of inventory valuation differ from actual results.

FINANCIAL REVIEW (Continued)
     Business Combinations: We account for acquired businesses using the acquisition method of accounting, which requires that the assets acquired and liabilities assumed be recorded at the date of acquisition at their respective fair values. Any excess of the purchase price over the estimated fair values of the net assets acquired is recorded as goodwill.
     Prior to April 1, 2009, amounts allocated to acquired in-process research and development (“IPR&D”) were expensed at the date of acquisition. Effective April 1, 2009, acquired IPR&D is measured at fair value using market participant assumptions and initially capitalized as an indefinite-lived intangible asset. Capitalized IPR&D is amortized over its estimated useful life once the asset is put in service. Capitalized IPR&D is reviewed for impairment whenever events or changes in circumstances indicate that we will not be able to recover the asset’s carrying amount. The judgments made in determining the estimated fair value assigned to each class of assets acquired and liabilities assumed, as well as asset lives, can materially impact our results of operations. The valuations are based on information available near the acquisition date and are based on expectations and assumptions that have been deemed reasonable by management. Effective April 1, 2009, contingent consideration is measured at its acquisition-date fair value. Contingent consideration classified as a liability is remeasured at fair value at the end of each subsequent reporting period and changes to the fair value are included in the current period’s earnings. Contingent consideration classified as equity is not remeasured subsequently.
     Several methods may be used to determine the fair value of assets acquired and liabilities assumed. For intangible assets, we typically use the income method. This method starts with a forecast of all of the expected future net cash flows for each asset or liability acquired. 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. Some of the more significant estimates and assumptions inherent in the income method or other methods 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 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. Refer to Financial Note 2, “Business Combinations and Investments,” to the consolidated financial statements appearing in this Annual Report on Form 10-K for additional information regarding our acquisitions.
     Goodwill: As a result of acquiring businesses, we have $3,568 million and $3,528 million of goodwill at March 31, 2010 and 2009. We maintain goodwill assets on our books unless the assets are considered to be impaired. We perform an impairment test on goodwill balances annually in the fourth quarter 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.
     Impairment testing is conducted at the reporting unit level, which is generally defined as 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 unit. Components that have essentially similar operations, products, services and customers are aggregated as a single reporting unit. Management judgment is involved in determining which components may be combined and changes in these combinations could affect the outcome of the testing.

FINANCIAL REVIEW (Continued)
     Impairment tests require that we first compare the carrying value of net assets to the estimated fair value of net assets for the reporting units. If the carrying value exceeds the fair value, a second step would be performed to calculate the amount of impairment, which would be recorded as a charge in our consolidated statements of operations. Fair values can be determined using the market, income or cost approach. To estimate the fair value of our reporting units, we 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 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 rate of return. In addition, we compare the aggregate fair value of our reporting units to our market capitalization as further corroboration of the fair value.
     Some of the more significant estimates and assumptions inherent in the goodwill impairment estimation process using the market approach include the selection of appropriate guideline companies, the determination of market value multiples for both the guideline companies and 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 discounted cash flow method, which reflects capital market conditions and the specific risks associated with the business. 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.
     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. The 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 review date and are based on expectations and assumptions that have been deemed reasonable by management. Any changes in key assumptions, including failure to meet business plans, a further deterioration in the market or other unanticipated events and circumstances, may affect the accuracy or validity of such estimates and could potentially result in an impairment charge.
     In 2010 and 2009, we concluded that there were no impairments of goodwill as the fair value of each reporting unit exceeded its carrying value.
     Supplier Incentives: Fees for service and other incentives received from suppliers, relating to the purchase or distribution of inventory, are generally reported as a reduction to cost of goods sold. We consider these fees and other incentives to represent product discounts and as a result, the amounts are recorded as a reduction of product cost and are recognized through cost of goods sold upon the sale of the related inventory.
     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 carefully considering the status of current outstanding claims, historical experience with the suppliers, the specific incentive programs and any other pertinent information available. We evaluate the amounts due from suppliers on a continual basis and adjust the reserve estimates when appropriate based on changes in factual circumstances. As of March 31, 2010 and 2009, supplier reserves were $89 million and $113 million. All of the supplier reserves at March 31, 2010 and 2009 pertain to our Distribution Solutions segment. A hypothetical 0.1% percentage increase or decrease in the supplier reserve as a percentage of trade payables would have resulted in an increase or decrease in the cost of sales of approximately $13 million in 2010. The ultimate outcome of any amounts due from our suppliers may be different from our estimate.

     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. 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. We had deferred income tax assets (net of valuation allowances) of $1,187 million and $1,447 million at March 31, 2010 and 2009 and deferred tax liabilities of $1,845 million and $1,889 million. Deferred tax assets primarily consist of net loss and credit carryforwards and timing differences on our compensation and benefit related accruals. Deferred tax liabilities primarily consist of basis differences for inventory valuation (including inventory valued at LIFO) and other assets. We established valuation allowances of $97 million against certain deferred tax assets, which primarily relate to federal, state and foreign loss carryforwards for which the ultimate realization of future benefits is uncertain. 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 cash flows could be materially impacted.
     If our assumptions and estimates described above were to change, an increase/decrease of 1% in our effective tax rate as applied to income from continuing operations would have increased/decreased tax expense by approximately $19 million, or $0.07 per diluted share, for 2010.
     Share-Based Compensation: Our compensation programs include share-based compensation. We account for all share-based compensation transactions using a fair-value based measurement method. The share-based compensation expense is recognized, for the portion of the awards that is ultimately expected to vest, on a straight-line basis over the requisite service period for those awards with graded vesting and service conditions. For awards with performance conditions and multiple vest dates, we recognize the expense on a graded vesting basis. For awards with performance conditions and a single vest date, we recognize the expense on a straight-line basis.
     We estimate the grant-date fair value of employee stock options using the Black-Scholes options-pricing model. We believe that it is difficult to accurately measure the value of an employee stock option. Our estimates of employee stock option values rely on estimates of factors we input into the model. The key factors involve an estimate of future uncertain events. The key factors influencing the estimation process, among others, are the expected life of the option, the expected stock price volatility factor and the expected dividend yield. In determining the expected life of the option, we primarily use historical experience as our best estimate of future exercise patterns. We use a combination of historical and implied market volatility to determine the expected stock price volatility factor. We believe that this market-based input provides a better estimate of our future stock price movements and is consistent with employee stock option valuation considerations. Once the fair values of employee stock options are determined, current accounting practices do not permit them to be changed, even if the estimates used are different from actual experience.

FINANCIAL REVIEW (Continued)
     In addition, we develop an estimate of the number of share-based awards, which will ultimately vest primarily based on historical experience. Changes in the estimated forfeiture rate can have a material effect on share-based compensation expense. If the actual forfeiture rate is higher than the estimated forfeiture rate, then an adjustment is made to increase the estimated forfeiture rate, which will result in a decrease to the expense recognized in the financial statements. If the actual forfeiture rate is lower than the estimated forfeiture rate, then an adjustment is made to decrease the estimated forfeiture rate, which will result in an increase to the expense recognized in the financial statements. We re-assess the estimated forfeiture rate established upon grant periodically throughout the requisite service period. Such estimates are revised if they differ materially from actual forfeitures. As required, the forfeiture estimates will be adjusted to reflect actual forfeitures when an award vests. The actual forfeitures in future reporting periods could be materially higher or lower than our current estimates.
     Our assessments of estimated share-based compensation charges are affected by our stock price as well as assumptions regarding a number of complex and subjective variables and the related tax impact. These variables include the volatility of our stock price, employee stock option exercise behavior, timing, number and types of annual share-based awards and the attainment of performance goals. As a result, the future share-based compensation expense may differ from the Company’s historical amounts.
     Loss Contingencies: We are subject to various claims, other 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. We record a provision for a liability when management believes that it is both probable that a liability has been incurred and the amount of the loss can be reasonably estimated. Management reviews these provisions at least quarterly and adjusts them to reflect the impact of negotiations, settlements, rulings, advice of legal counsel and other information and events pertaining to a particular case. Because litigation outcomes are inherently unpredictable, these decisions often involve a series of complex assessments by management about future events that can rely heavily on estimates and assumptions and it is possible that the actual cost of these matters could impact our earnings, either negatively or positively, in the period of their resolution.
FINANCIAL CONDITION, LIQUIDITY AND CAPITAL RESOURCES
     We expect our available cash generated from operations, together with our existing sources of liquidity from our accounts receivable sales facility and short-term borrowings under the revolving credit facility and commercial paper, will be sufficient to fund our long-term and short-term capital expenditures, working capital and other cash requirements. In addition, from time-to-time, we may access the long-term debt capital markets to discharge our other liabilities.
     Net cash flow from operating activities was $2,316 million in 2010, compared to $1,351 million in 2009 and $869 million in 2008. Operating activities for 2010 were primarily affected by improved management of drafts and accounts payable, partially offset by an increase in inventories due to our revenue growth and the AWP litigation private payor settlement payments of $350 million. Cash flows from operations can also be significantly impacted by factors such as the timing of receipts from customers and payments to vendors.
     Operating activities for 2009 include a non-cash charge of $493 million and the related income tax benefit of $182 million for the AWP litigation charge. Operating activities for 2009 reflect an increase in receivables primarily associated with our revenue growth as well as longer payment terms for certain customers and improvement in our net financial inventory (inventory, net of drafts and accounts payable).
     Operating activities for 2008 were affected by a use of cash of $962 million due to the release of restricted cash for our Consolidated Securities Litigation Action. In addition, operating activities in 2008 reflect changes in our working capital accounts due to revenue growth.

     Net cash used in investing activities was $309 million in 2010 compared to $727 million in 2009 and $5 million in 2008. Investing activities for 2010 include $199 million and $179 million in capital expenditures for property acquisitions and capitalized software and the release of $55 million of restricted cash from escrow related to the AWP litigation settlement payments. Investing activities for 2009 included $358 million of cash payments for business acquisitions, including the McQueary Brothers acquisition for approximately $190 million. Investing activities for 2008 benefited from the $962 million release of restricted cash for our Consolidated Securities Litigation Action. Investing activities included $610 million in 2008 of cash paid for business acquisitions, including OTN.
     Financing activities utilized cash of $421 million in 2010, provided cash of $178 million in 2009 and utilized cash of $1,470 million in 2008. Financing activities for 2010 include $323 million in cash paid for share repurchases and $218 million in cash paid on our long-term debt, which primarily consisted of $215 million paid on the maturity of our 9.13% Series C Senior Notes in March 2010. Financing activities for 2009 include our February 2009 issuance of $350 million of 6.50% notes due 2014 and $350 million of 7.50% notes due 2019. Net proceeds of $693 million from the issuance of the notes, after discounts and offering expenses, were used by the Company for general corporate purposes. Financing activities for 2009 were also impacted by $502 million of cash paid for share repurchases, $116 million of dividends paid and $97 million of cash receipts from employees’ exercises of stock options.
     Financing activities for 2008 included $1.7 billion of cash paid for stock repurchases and $70 million of dividends paid, partially offset by $354 million of cash receipts from common stock issuances.
     The Company’s Board has authorized the repurchase of McKesson’s common stock from time-to-time in open market transactions, privately negotiated transactions, through accelerated share repurchase programs, or by any combination of such methods. The timing of any repurchases and the actual number of shares repurchased will depend on a variety of factors, including our stock price, corporate and regulatory requirements, restrictions under our debt obligations and other market and economic conditions. This authorization is described in more detail in Financial Note 19, “Stockholders’ Equity,” to the consolidated financial statements appearing in this Annual Report on Form 10-K. During 2010, 2009 and 2008, the Company repurchased $299 million, $484 million and $1,686 million of its common stock at average prices of $41.47, $50.52 and $59.48. As of March 31, 2010, $531 million remained available for future repurchases under the outstanding April 2008 Board approved share repurchase plan. In April 2010, the Board authorized the repurchase of up to an additional $1.0 billion of the Company’s common stock.
     In July 2008, the Board authorized the retirement of shares of the Company’s common stock that may be repurchased from time-to-time pursuant to its stock repurchase program. During the second quarter of 2009, all of the 4 million repurchased shares, which we purchased for $204 million, were formally retired by the Company. The retired shares constitute authorized but unissued shares. We elected to allocate any excess of share repurchase price over par value between additional paid-in capital and retained earnings. As such, $165 million was recorded as a decrease to retained earnings.
     The Company anticipates that it will continue to pay quarterly cash dividends in the future. However, the payment and amount of future dividends remain within the discretion of the Board and will depend upon the Company’s future earnings, financial condition, capital requirements and other factors.
     Although we believe that our operating cash flow, financial assets, current access to capital and credit markets, as evidenced by our debt issuance in February 2009, including our existing credit and sales facilities, will give us the ability to meet our financing needs for the foreseeable future, there can be no assurance that continued or increased volatility and disruption in the global capital and credit markets will not impair our liquidity or increase our costs of borrowing.

(3)   Ratio is computed as net income, divided by a five-quarter average of stockholders’ equity.
     Our cash and equivalents balance as of March 31, 2010, included approximately $1.2 billion of cash held by our subsidiaries outside of the United States. Although the vast majority of cash held outside the United States is available for repatriation, doing so could subject us to U.S. federal, state and local income tax. We may temporarily access cash held by foreign subsidiaries without subjecting us to U.S. federal, state and local income tax through intercompany loans. A notice issued by the IRS in January 2009 announced that the Treasury Department will, for a temporary period, extend the permitted duration of such intercompany loans that qualify for suspended deemed dividend treatment under Section 956 of the Internal Revenue Code of 1986, as amended. Pursuant to the IRS notice, such intercompany loans from foreign subsidiaries to the U.S. parent must be less than 60 days in duration and borrowing activities cannot exceed 180 cumulative days during the year. At March 31, 2010, there were no intercompany loans outstanding. The position set forth in the notice will apply for the Company until March 31, 2011.
     Working capital primarily includes cash and cash equivalents, receivables and inventories, net of drafts and accounts payable, deferred revenue and other current liabilities. Our Distribution Solutions segment requires a substantial investment in working capital that is 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 customer requirements.
     Consolidated working capital increased at March 31, 2010, compared to March 31, 2009, primarily due to increases in cash and cash equivalents, partially offset by an increase in net financial inventory and repayment of $215 million of our long-term debt in March 2010. Consolidated working capital increased at March 31, 2009, compared to March 31, 2008, primarily due to increases in cash and cash equivalents and accounts receivable, partially offset by our $493 million AWP litigation accrual and a higher current portion of long-term debt.
     Our ratio of net debt to net capital employed decreased at March 31, 2010, compared to March 31, 2009, primarily reflecting an increase in cash and cash equivalents and repayment of $215 million of our long-term debt in March 2010. This ratio decreased at March 31, 2009, compared to March 31, 2008, primarily reflecting an increase in cash and cash equivalents, partially offset by our issuance of $700 million of long-term debt.
     The Company has paid quarterly cash dividends at the rate of $0.06 per share on its common stock since the fourth quarter of 1999. In April 2008, the quarterly dividend was raised from six cents to twelve cents per share. The Company anticipates that it will continue to pay quarterly cash dividends in the future. However, the payment and amount of future dividends remain within the discretion of the Board and will depend upon the Company’s future earnings, financial condition, capital requirements and other factors. In 2010, 2009 and 2008, we paid total cash dividends of $131 million, $116 million and $70 million.

(1)   Represents maturities of the Company’s long-term obligations including an immaterial amount of capital lease obligations. See Financial Note 12, “Long-Term Debt and Other Financing,” for further information.
 
(2)   Represents our estimated benefit payments for the unfunded benefit plans and minimum funding requirements for the pension plans.
 
(3)   Primarily represents interest that will become due on our fixed rate long-term debt obligations.
 
(4)   A purchase obligation is defined as an arrangement to purchase goods or services that is enforceable and legally binding on the Company. These obligations primarily relate to inventory purchases, capital commitments and service agreements.
 
(5)   Represents primarily agreements with certain of our customers’ financial institutions (primarily for our Canadian business) under which we have guaranteed the repurchase of inventory at a discount in the event these customers are unable to meet certain obligations to those financial institutions. Among other limitations, these inventories must be in resalable condition. The inventory repurchase agreements mostly range from one to two years. Customer guarantees range from one to five years and were primarily provided to facilitate financing for certain customers. The majority of our other customer guarantees are secured by certain assets of the customer. At March 31, 2010, the maximum amounts of inventory repurchase guarantees and other customer guarantees were $124 million and $17 million. We consider it unlikely that we would make significant payments under these guarantees and accordingly, no amounts had been accrued at March 31, 2010. Refer to Financial Note 17, “Financial Guarantees and Warranties,” for further information.
 
(6)   Represents minimum rental payments for operating leases. See Financial Note 16, “Lease Obligations,” for further information.
     At March 31, 2010, the liability recorded for uncertain tax positions, excluding associated interest and penalties, was approximately $514 million. This liability represents an estimate of tax positions that the Company has taken in its tax returns which may ultimately not be sustained upon examination by the tax authorities. Since the ultimate amount and timing of any future cash settlements cannot be predicted with reasonable certainty, the estimated liability has been excluded from the contractual obligations table.
     In addition, at March 31, 2010, our banks and insurance companies have issued $111 million of standby letters of credit and surety bonds, which were issued on our behalf mostly related to our customer contracts and in order to meet the security requirements for statutory licenses and permits, court and fiduciary obligations and our workers’ compensation and automotive liability programs.

FINANCIAL REVIEW (Continued)
     Credit Resources:
     We fund our working capital requirements primarily with cash and cash equivalents, our accounts receivable sales facility, short-term borrowings under the revolving credit facility and commercial paper.
     Long-Term Debt
     In March 2010, we repaid our $215 million 9.13% Series C Senior notes, which had matured.
     On February 12, 2009, we issued 6.50% notes due February 15, 2014, (the “2014 Notes”) in an aggregate principal amount of $350 million and 7.50% notes due February 15, 2019, (the “2019 Notes”) in an aggregate principal amount of $350 million. Interest is payable on February 15 and August 15 of each year beginning on August 15, 2009. The 2014 Notes will mature on February 15, 2014 and the 2019 Notes will mature on February 15, 2019. We utilized net proceeds, after discounts and offering expenses, of $693 million from the issuance of the 2014 Notes and 2019 Notes for general corporate purposes.
     Our senior debt credit ratings from S&P, Fitch, and Moody’s are currently A-, BBB+ and Baa3, and our commercial paper ratings are currently A-2, F-2 and P-3. Our ratings outlook is stable with S&P, Fitch, and Moody’s.
     Accounts Receivable Sales Facility
     In May 2009, we renewed our accounts receivable sales facility for an additional one-year period under terms similar to those previously in place. The renewed facility will expire in mid-May 2010. Based on our existing accounts receivable sales facility agreement, we anticipate that activity under this facility may, for U.S. GAAP purposes, be considered as a secured borrowing rather than a sale under accounting standards that will become effective for us on April 1, 2010. We anticipate renewing this facility before its expiration. The aggregate commitment of the purchasers under this facility is $1.1 billion, although from time-to-time, the available amount may be less than that amount based on concentration limits and receivable eligibility requirements.
     Through this facility, McKesson Corporation, the parent company, sells certain U.S. pharmaceutical trade accounts receivable on a non-recourse basis to a wholly-owned and consolidated subsidiary, which then sells these receivables to a special purpose entity (“SPE”), which is a wholly-owned, bankruptcy-remote subsidiary of McKesson Corporation that is consolidated in our financial statements. This SPE then sells undivided interests in the receivables to third-party purchaser groups, each of which includes commercial paper conduits, which are special purpose legal entities administered by financial institutions.
     Additional information regarding our accounts receivable sales facility is included in Financial Notes 1 and 12, “Significant Accounting Policies” and “Long-Term Debt and Other Financing,” to the consolidated financial statements appearing in this Annual Report on Form 10-K.
     Revolving Credit Facility
     We have a syndicated $1.3 billion five-year senior unsecured revolving credit facility, which expires in June 2012. Borrowings under this credit facility bear interest based upon either a Prime rate or the London Interbank Offering Rate. There were no borrowings under this facility in 2010 and $279 million for 2009. As of March 31, 2010 and 2009, there were no amounts outstanding under this facility.

McKESSON CORPORATION
FINANCIAL REVIEW (Continued)
     Commercial Paper
     We issued and repaid commercial paper of nil and approximately $3.3 billion and $260 million in 2010, 2009 and 2008. There were no commercial paper issuances outstanding at March 31, 2010 and 2009.
     Debt Covenant
     Our various borrowing facilities and long-term debt are subject to certain covenants. Our principal debt covenant is our debt to capital ratio under our unsecured revolving credit facility, which cannot exceed 56.5%. If we exceed this ratio, repayment of debt outstanding under the revolving credit facility could be accelerated. As of March 31, 2010, this ratio was 23.4% and we were in compliance with our other financial covenants. A reduction in our credit ratings, or the lack of compliance with our covenants, could negatively impact our ability to finance operations or issue additional debt at acceptable interest rates.
     Funds necessary for future debt maturities and our other cash requirements are expected to be met by existing cash balances, cash flow from operations, existing credit sources and other capital market transactions.
RELATED PARTY BALANCES AND TRANSACTIONS
     Information regarding our related party balances and transactions is included in Financial Note 20, “Related Party Balances and Transactions,” to the consolidated financial statements appearing in this Annual Report on Form 10-K.
NEW ACCOUNTING PRONOUNCEMENTS
     New accounting pronouncements that we have recently adopted, as well as those that have been recently issued but not yet adopted by us, are included in Financial Note 1, “Significant Accounting Policies,” to the consolidated financial statements appearing in this Annual Report on Form 10-K.

McKESSON CORPORATION
FINANCIAL REVIEW (Concluded)
Item 7A. Quantitative and Qualitative Disclosures about Market Risk
     Interest rate risk: Our long-term debt bears interest predominately at fixed rates, whereas our short-term borrowings are at variable interest rates. If the underlying weighted average interest rate on our variable rate debt were to have changed by 50 bp in 2010, interest expense would not have been materially different from that reported.
     Our cash and cash equivalents balances earn interest at variable rates. Should interest rates decline, our interest income may be negatively impacted. If the underlying weighted average interest rate on our cash and cash equivalents balances changed by 50 bp in 2010, interest income would have increased or decreased by approximately $16 million.
     As of March 31, 2010 and 2009, the net fair value liability of financial instruments with exposure to interest rate risk was approximately $2,548 million and $2,545 million. The estimated fair value of our long-term debt and other financing was determined using quoted market prices and other inputs that were derived from available market information and may not be representative of actual values that could have been realized or that will be realized in the future. Fair value is subject to fluctuations based on our performance, our credit ratings, changes in the value of our stock and changes in interest rates for debt securities with similar terms.
     Foreign exchange risk: We derive revenues and earnings from Canada, the United Kingdom, Ireland, other European countries, Israel, Asia Pacific and Mexico, which exposes us to changes in foreign exchange rates. We seek to manage our foreign exchange risk in part through operational means, including managing same currency revenues in relation to same currency costs, and same currency assets in relation to same currency liabilities. Foreign exchange risk is also managed through the use of foreign currency forward-exchange contracts. These contracts are used to offset the potential earnings effects from mostly intercompany foreign currency investments and loans. As of March 31, 2010, an adverse 10% change in quoted foreign currency exchange rates would not have had a material impact on our net fair value of financial instruments that have exposure to foreign currency risk.

McKESSON CORPORATION
MANAGEMENT’S ANNUAL REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING
     The management of McKesson Corporation is responsible for establishing and maintaining an adequate system of internal control over financial reporting, as such term is defined in Exchange Act Rules 13a-15(f) and 15d-15(f). With the participation of the Chief Executive Officer and the Chief Financial Officer, our management conducted an assessment of the effectiveness of our internal control over financial reporting based on the framework and criteria established in Internal Control—Integrated Framework, issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on this assessment, our management has concluded that our internal control over financial reporting was effective as of March 31, 2010.
     Deloitte & Touche LLP, an independent registered public accounting firm, audited the financial statements included in this Annual Report on Form 10-K and has also audited the effectiveness of the Company’s internal control over financial reporting as of March 31, 2010. This audit report appears on page 52 of this Annual Report on Form 10-K.

McKESSON CORPORATION
REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
To the Board of Directors and Stockholders of McKesson Corporation:
     We have audited the accompanying consolidated balance sheets of McKesson Corporation and subsidiaries (the “Company”) as of March 31, 2010 and 2009, and the related consolidated statements of operations, stockholders’ equity and cash flows for each of the three fiscal years in the period ended March 31, 2010. Our audit also included the consolidated financial statement schedule (“financial statement schedule”) listed in the Index at Item 15(a). We also have audited the Company’s internal control over financial reporting as of March 31, 2010, based on criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. The Company’s management is responsible for these financial statements and financial statement schedule, 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 financial statement schedule, and an opinion on the Company’s internal control over financial reporting based on our audits.
     We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement and whether effective internal control over financial reporting was maintained in all material respects. Our audits of the financial statements included examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. 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.
     A company’s internal control over financial reporting is a process designed by, or under the supervision of, the company’s principal executive and principal financial officers, or persons performing similar functions, and effected by the company’s board of directors, management, and other personnel 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.
     Because of the inherent limitations of internal control over financial reporting, including the possibility of collusion or improper management override of controls, material misstatements due to error or fraud may not be prevented or detected on a timely basis. Also, projections of any evaluation of the effectiveness of the internal control over financial reporting to future periods are subject to the risk that the controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
     In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of McKesson Corporation and subsidiaries as of March 31, 2010 and 2009, and the results of their operations and their cash flows for each of the three fiscal years in the period ended March 31, 2010, in conformity with accounting principles generally accepted in the United States of America. Also, in our opinion, such financial statement schedule, when considered in relation to the basic consolidated financial statements taken as a whole, presents fairly, in all material respects, the information set forth therein. Also, in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of March 31, 2010, based on the criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission.

McKESSON CORPORATION
FINANCIAL NOTES
1. Significant Accounting Policies
     Nature of Operations: McKesson Corporation (“McKesson,” the “Company,” or “we” and other similar pronouns) is a corporation that delivers medicines, pharmaceutical supplies, information and care management products and services designed to reduce costs and improve quality across the healthcare industry.
     We conduct our business through two operating segments, McKesson Distribution Solutions and McKesson Technology Solutions, as further described in Financial Note 21, “Segments of Business.”
     Basis of Presentation: The consolidated financial statements and accompanying notes are prepared in accordance with U. S. generally accepted accounting principles (“GAAP”). The consolidated financial statements of McKesson include the financial statements of all wholly-owned subsidiaries, majority-owned or controlled companies and certain immaterial variable interest entities (“VIEs”) of which the Company is the primary beneficiary. We evaluate our ownership, contractual and other interests in entities to determine if they are VIEs, if we have a variable interest in those entities and the nature and extent of those interests. These evaluations are highly complex and involve judgment and the use of estimates and assumptions based on available historical information and management’s judgment, among other factors. Intercompany transactions and balances have been eliminated.
     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 we 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.
     Cash and Cash Equivalents: All highly liquid debt instruments purchased with original maturity of three months or less at the date of acquisition are included in cash and cash equivalents.
     We maintain cash and cash equivalents with several financial institutions. Bank deposits may exceed the amount of federal deposit insurance. Cash equivalents may be invested in money market funds. We mitigate the risk of our short-term investment portfolio by investing the majority of funds in U.S. government securities, depositing funds with reputable financial institutions and monitoring risk profiles and investment strategies of money market funds.
     Restricted Cash: Cash that is subject to legal restrictions or is unavailable for general operating purposes is classified as restricted cash and included within prepaid expenses and other in the consolidated balance sheets. At March 31, 2010 and 2009, restricted cash was not material.
     Marketable Securities Available for Sale: We carry our marketable securities, which are available for sale, at fair value and they are included in prepaid expenses and other in the consolidated balance sheets. The net unrealized gains and losses, net of the related tax effect, computed in marking these securities to market have been reported within stockholders’ equity. At March 31, 2010 and 2009, marketable securities were not material.

McKESSON CORPORATION
FINANCIAL NOTES (Continued)
     Concentrations of Credit Risk and Receivables: Our trade receivables are subject to a concentration of credit risk with customers primarily in our Distribution Solutions segment. At March 31, 2010, revenues and accounts receivable from our ten largest customers accounted for approximately 53% of consolidated revenues and 45% of accounts receivable. At March 31, 2010, revenues and accounts receivable from our two largest customers, CVS Caremark Corporation (“CVS”) and Rite Aid Corporation (“Rite Aid”), represented approximately 15% and 12% of total consolidated revenues and 14% and 10% of accounts receivable. As a result, our sales and credit concentration is significant. A default in payment, a material reduction in purchases from these, or any other large customers or the loss of a large customer could have a material adverse impact on our financial condition, results of operations and liquidity. In addition, trade receivables are subject to a concentration 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 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 amounts.
     Inventories: We report inventories at the lower of cost or market (“LCM”). Inventories for our Distribution Solutions segment consist of merchandise held for resale. For our Distribution Solutions segment, the majority of the cost of domestic inventories is determined using the last-in, first-out (“LIFO”) method and the cost of Canadian inventories is determined using the first-in, first-out (“FIFO”) method. Technology Solutions segment inventories consist of computer hardware with cost determined by the standard cost method. Rebates, fees, cash discounts, allowances, chargebacks and other incentives received from vendors are generally accounted for as a reduction in the cost of inventory and are recognized when the inventory is sold. Total inventories were $9.4 billion and $8.5 billion at March 31, 2010 and 2009.
     The LIFO method was used to value approximately 87% and 88% of our inventories at March 31, 2010 and 2009. At March 31, 2010 and 2009, our LIFO reserves, net of LCM adjustments, were $93 million and $85 million. LIFO reserves include both pharmaceutical and non-pharmaceutical products. In 2010 and 2009, we recognized net LIFO expense of $8 million and in 2008, net LIFO credits of $14 million within our consolidated statements of operations. In 2010, our $8 million net LIFO expense related to our non-pharmaceutical products. A LIFO expense is recognized when the net effect of price increases on branded pharmaceuticals and non-pharmaceutical products held in inventory exceeds the impact of price declines and shifts towards generic pharmaceuticals, including the effect of branded pharmaceutical products that have lost market exclusivity. A LIFO credit is recognized when the impact of price declines and shifts towards generic pharmaceuticals exceeds the impact of price increases on branded pharmaceuticals and non-pharmaceutical products held in inventory.
     We believe that the FIFO 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 inventory as valued under FIFO. Primarily due to continued deflation in generic pharmaceutical inventories, pharmaceutical inventories at LIFO were $112 million and $107 million higher than FIFO as of March 31, 2010 and 2009. As a result, in 2010 and 2009, we recorded LCM charges of $5 million and $64 million in cost of sales within our consolidated statements of operations to adjust our LIFO inventories to market.
     Property, Plant and Equipment: We state our property, plant and equipment at cost and depreciate them under the straight-line method at rates designed to distribute the cost of properties over estimated service lives ranging from one to 30 years.

     Capitalized Software Held for Sale: Development costs for software held for sale, which primarily pertain to our Technology Solutions segment, are capitalized once a project has reached the point of technological feasibility. Completed projects are amortized after reaching the point of general availability using the straight-line method based on an estimated useful life of approximately three years. We monitor the net realizable value of capitalized software held for sale to ensure that the investment will be recovered through future sales.
     Additional information regarding our capitalized software expenditures is as follows:

     Goodwill: Goodwill is tested for impairment on an annual basis or more frequently if indicators for potential impairment exist. Impairment testing is conducted at the reporting unit level, which is generally defined as 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 unit. Components that have essentially similar operations, products, services and customers are aggregated as a single reporting unit.
     Impairment tests require that we first compare the carrying value of net assets to the estimated fair value of net assets for the reporting units. If the carrying value exceeds the fair value, a second step is performed to calculate the amount of impairment, which would be recorded as a charge in the consolidated statements of operations. The fair value of a reporting unit is based upon a number of considerations including projections of revenues, earnings and discounted cash flows and determination of market value multiples for similar businesses or guideline companies whose securities are actively traded in public markets. The discount rate used for cash flows reflects capital market conditions and the specific risks associated with the business. In addition, we compare the aggregate of the reporting units’ fair value to the Company’s market capitalization as a further corroboration of the fair value. The testing requires a complex series of assumptions and judgment 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. There were no goodwill impairments during 2010, 2009, or 2008.
     Intangible assets: Currently all of our intangible assets are subject to amortization and are amortized over their estimated period of benefit, ranging from one to fifteen years. We evaluate the recoverability of intangible assets periodically and take into account events or circumstances that warrant revised estimates of useful lives or that indicate that impairment exists. No material impairments of intangible assets have been identified during any of the years presented.
     Capitalized Software Held for Internal Use: We capitalize costs of software held for internal use during the application development stage of a project and amortize those costs over the assets’ estimated useful lives ranging from one to ten years. As of March 31, 2010 and 2009, capitalized software held for internal use was $483 million and $475 million, net of accumulated amortization of $665 million and $567 million, and was included in other assets in the consolidated balance sheets.
     Insurance Programs: Under our insurance programs, we seek to obtain coverage for catastrophic exposures as well as those risks required to be insured by law or contract. It is our policy to retain a significant portion of certain losses primarily related to workers’ compensation and comprehensive general, product and vehicle liability. Provisions for losses expected under these programs are recorded based upon our estimate of the aggregate liability for claims incurred as well as for claims incurred but not yet reported. Such estimates utilize certain actuarial assumptions followed in the insurance industry.

     Revenue Recognition: Revenues for our Distribution Solutions segment are recognized when product is delivered and title passes to the customer or when services have been rendered and there are no further obligations to customers.
     Revenues are recorded net of sales returns, allowances, rebates and other incentives. Our sales return policy generally allows customers to return products only if they can be resold for value or returned to suppliers for full credit. Sales returns are accrued based on estimates at the time of sale to the customer. Sales returns from customers were approximately $1,233 million, $1,216 million and $1,093 million in 2010, 2009 and 2008. Taxes collected from customers and remitted to governmental authorities are presented on a net basis; that is, they are excluded from revenues.
     The revenues for our Distribution Solutions segment include large volume sales of pharmaceuticals to a limited number of large customers who warehouse their own product. We order bulk product from the manufacturer, receive and process the product through our central distribution facility and deliver the bulk product (generally in the same form as received from the manufacturer) directly to our customers’ warehouses. Sales to customers’ warehouses amounted to $21.4 billion in 2010, $25.8 billion in 2009 and $27.7 billion in 2008. We also record revenues for direct store deliveries from most of these same customers. Direct store deliveries are shipments from the manufacturer to our customers of a limited category of products that require special handling. We assume the primary liability to the manufacturer for these products.
     Revenues are recorded gross when we are the primary party obligated in the transaction, take title to and possession of the inventory, are subject to inventory risk, have latitude in establishing prices, assume the risk of loss for collection from customers as well as delivery or return of the product, are responsible for fulfillment and other customer service requirements, or the transactions have several but not all of these indicators.
     Our Distribution Solutions segment also engages in multiple-element arrangements, which may contain a combination of various products and services. Revenue from a multiple element arrangement is allocated to the separate elements based on estimates of fair value and recognized in accordance with the revenue recognition criteria applicable to each element. If fair value cannot be established for any undelivered element, all of the arrangement’s revenue is deferred until delivery of the last element has occurred and services have been performed or until fair value can objectively be determined for any remaining undelivered elements.
     Revenues for our Technology Solutions segment are generated primarily by licensing software and software systems (consisting of software, hardware and maintenance support), and providing outsourcing and professional services. Revenue for this segment is recognized as follows:
     Software systems are marketed under information systems agreements as well as service agreements. Perpetual software arrangements are recognized at the time of delivery or under the percentage-of-completion method based on the terms and conditions in the contract. Contracts accounted for under the percentage-of-completion method are generally measured based on the ratio of labor costs incurred to date to total estimated labor costs to be incurred. Changes in estimates to complete and revisions in overall profit estimates on these contracts are charged to earnings in the period in which they are determined. We accrue for contract losses if and when the current estimate of total contract costs exceeds total contract revenue.
     Hardware revenues are generally recognized upon delivery. Revenue from multi-year software license agreements is recognized ratably over the term of the agreement. Software implementation fees are recognized as the work is performed or under the percentage-of-completion method. Maintenance and support agreements are marketed under annual or multi-year agreements and are recognized ratably over the period covered by the agreements. Subscription, content and transaction processing fees are generally marketed under annual and multi-year agreements and are recognized ratably over the contracted terms beginning on the service start date for fixed fee arrangements and recognized as transactions are performed beginning on the service start date for per-transaction fee arrangements. Remote processing service fees are recognized monthly as the service is performed. Outsourcing service revenues are recognized as the service is performed.

     We also offer certain products on an application service provider basis, making our software functionality available on a remote hosting basis from our data centers. The data centers provide system and administrative support, as well as hosting services. Revenue on products sold on an application service provider basis is recognized on a monthly basis over the term of the contract beginning on the service start date of products hosted.
     This segment also engages in multiple-element arrangements, which may contain any combination of software, hardware, implementation or consulting services, or maintenance services. When some elements are delivered prior to others in an arrangement and vendor-specific objective evidence of fair value (“VSOE”) 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.
     Our Technology Solutions segment also includes revenues from disease management programs provided to various states’ Medicaid programs. These service contracts include provisions for achieving certain cost-savings and clinical targets. If the targets are not met for certain of these contracts, a portion, or all, of the revenue must be refunded to the customer. We recognize revenue during the term of the contract by assessing actual performance against contractual targets and then determining the amount the customer would be legally obligated to pay if the contract terminated as of the measurement date. These assessments include estimates of medical claims and other data in accordance with the contract methodology. Because complete data is unavailable until six to nine months after the measurement period, there is generally a significant time delay between recording the accrual and the final settlement of the contract. If data is insufficient to assess performance or we have not met the targets, we defer recognition of the revenue. As of March 31, 2010 and 2009, we had deferred $26 million and $25 million related to these types of contracts, which was included in deferred revenue in the consolidated balance sheets. We generally have been successful in achieving performance targets under these agreements.
     Supplier Incentives: Fees for service and other incentives received from suppliers, relating to the purchase or distribution of inventory, are generally reported as a reduction to cost of goods sold. We consider these fees to represent product discounts and as a result, the fees are recorded as a reduction of product cost and recognized through cost of goods sold upon the sale of the related inventory.
     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 carefully considering the status of current outstanding claims, historical experience with the suppliers, the specific incentive programs and any other pertinent information available. We evaluate the amounts due from suppliers on a continual basis and adjust the reserve estimates when appropriate based on changes in factual circumstances. The ultimate outcome of any outstanding claim may be different than our estimate. As of March 31, 2010 and 2009, supplier reserves were $89 million and $113 million.
     Income Taxes: We account 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. 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 settlements. Deferred taxes are not provided on undistributed earnings of our foreign operations that are considered to be permanently reinvested.

     Foreign Currency Translation: Our international subsidiaries generally consider their local currency to be their functional currency. Assets and liabilities of these international subsidiaries are translated into U.S. dollars at year-end exchange rates and revenues and expenses are translated at average exchange rates during the year. Cumulative currency translation adjustments are included in accumulated other comprehensive income or losses in the stockholders’ equity section of the consolidated balance sheets. Realized gains and losses from currency exchange transactions are recorded in operating expenses in the consolidated statements of operations and were not material to our consolidated results of operations in 2010, 2009 or 2008.
     Derivative Financial Instruments: Derivative financial instruments are used principally in the management of foreign currency and interest rate exposures and are recorded on the consolidated balance sheets at fair value. If a derivative is designated as a fair value hedge, the changes in the fair value of the derivative and of the hedged item attributable to the hedged risk are recognized as a charge or credit to earnings. If the derivative is designated as a cash flow hedge, the effective portions of changes in the fair value of the derivative are recorded in accumulated other comprehensive income or losses and are recognized in the consolidated statements of operations when the hedged item affects earnings. We periodically evaluate hedge effectiveness and ineffective portions of changes in the fair value of cash flow hedges are recognized as a charge or credit to earnings. Derivative instruments not designated as hedges are marked-to-market at the end of each accounting period with the change included in earnings.
     Accounts Receivable Sales: At March 31, 2010, we had a $1.1 billion revolving receivables sales facility. Through this facility, McKesson Corporation, the parent company, sells certain U.S. pharmaceutical trade accounts receivable on a non-recourse basis to a wholly-owned and consolidated subsidiary, which then sells these receivables to a special purpose entity (“SPE”), which is a wholly-owned, bankruptcy-remote subsidiary of McKesson Corporation that is consolidated in our financial statements. This SPE then sells undivided interests in the receivables to third-party purchaser groups, each of which includes commercial paper conduits (“Conduits”), which are special purpose legal entities administered by financial institutions. Sales of undivided interests in the receivables by the SPE to the Conduits are accounted for as a sale because we have relinquished control of the receivables. Accordingly, accounts receivable sold under these transactions are excluded from receivables, net in the accompanying consolidated balance sheets. Receivables sold and receivables retained by the Company are carried at face value, which due to the short-term nature of its accounts receivable and terms of the facility, approximates fair value. McKesson receives cash in the amount of the face value for the undivided interests in the receivables sold. No gain or loss is recorded upon sale as fee charges from the Conduits are based upon a floating yield rate and the period the undivided interests remain outstanding. Fee charges from the Conduits are accrued at the end of each month and are recorded within administrative expenses in the consolidated statements of operations. Should we default under the accounts receivable sales facility, the Conduits are entitled to receive only collections on receivables owned by the SPE.
     We continue servicing the receivables sold. No servicing asset is recorded at the time of sale because we do not receive any servicing fees from third parties or other income related to servicing the receivables. We do not record any servicing liability at the time of sale as the receivables collection period is relatively short and the costs of servicing the receivables sold over the servicing period are insignificant. Servicing costs are recognized as incurred over the servicing period. See Financial Note 12, “Long-Term Debt and Other Financing,” for additional information.
     Share-Based Compensation: We account for all share-based compensation transactions using a fair-value based measurement method. The share-based compensation expense is recognized, for the portion of the awards that is ultimately expected to vest, on a straight-line basis over the requisite service period for those awards with graded vesting and service conditions. For awards with performance conditions and multiple vest dates, we recognize the expense on a graded vesting basis. For awards with performance conditions and a single vest date, we recognize the expense on a straight-line basis. The compensation expense recognized has been classified in the consolidated statements of operations or capitalized on the consolidated balance sheets in the same manner as cash compensation paid to our employees.

     Loss Contingencies: We are subject to various claims, other 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. We record a provision for a liability when management believes that it is both probable that a liability has been incurred and the amount of the loss can be reasonably estimated. Management reviews these provisions at least quarterly and adjusts them to reflect the impact of negotiations, settlements, rulings, advice of legal counsel and other information and events pertaining to a particular case. Because litigation outcomes are inherently unpredictable, these decisions often involve a series of complex assessments by management about future events that can rely heavily on estimates and assumptions and it is possible that the actual cost of these matters could impact our earnings, either negatively or positively, in the period of their resolution.
     Recently Adopted Accounting Pronouncements
     Accounting Standards CodificationTM: Effective July 1, 2009, we adopted the Financial Accounting Standards Board (“FASB”) Accounting Standards CodificationTM (“ASC” or “Codification”) as the source of authoritative U.S. GAAP recognized by the FASB to be applied by nongovernmental entities. Rules and interpretive releases of the U.S. Securities and Exchange Commission (“SEC”) under authority of federal securities laws are also sources of authoritative U.S. GAAP for SEC registrants. The Codification superseded all then-existing non-SEC accounting and reporting standards. The adoption of the Codification did not have a material effect on our consolidated financial statements.
     Fair Value Measurements and Disclosures: In September 2006, the FASB issued new standards that provide a consistent definition of fair value that focuses on exit price, prioritizes the use of market-based inputs over entity-specific inputs for measuring fair value and establishes a three-level hierarchy for fair value measurements. In February 2008, the FASB permitted companies to defer the effective date of these standards for one year for nonfinancial assets and nonfinancial liabilities that are recognized or disclosed at fair value in the consolidated financial statements on a nonrecurring basis. On April 1, 2008, we adopted the fair value measurements and disclosures for financial assets and financial liabilities and for nonfinancial assets and nonfinancial liabilities that are remeasured at least annually. At that time, we elected to defer adoption of the standards for one year, to April 1, 2009, for nonfinancial assets and nonfinancial liabilities that are recognized or disclosed at fair value in the financial statements on a nonrecurring basis. The standards were applied prospectively and their adoption did not have a material effect on our consolidated financial statements. In April 2009, the FASB issued new standards for estimating fair value when an asset or liability experiences a significant decrease in volume and activity relative to its normal market activity. In addition, these standards identify circumstances that may indicate whether a transaction is not orderly. Retrospective application to a prior interim or annual reporting period was not permitted. On April 1, 2009, we adopted this standard, which did not have a material effect on our consolidated financial statements.
     Effective October 1, 2009, we adopted amended standards on two issues: 1) determining the fair value of a liability when a quoted price in an active market for an identical liability is not available and 2) measuring and disclosing the fair value of certain investments on the basis of the investments’ net asset value per share or its equivalent. This adoption did not have a material effect on our consolidated financial statements. However, these amended standards may affect the valuation of future investments.
     In January 2010, the FASB issued amended standards that clarify and provide additional disclosure requirements related to recurring and non-recurring fair value measurements. These standards also amend requirements for employers’ disclosures about postretirement benefit plan assets to conform to the fair value disclosure requirement. On January 1, 2010, we adopted these amended standards, except for the disclosures about the roll forward of activity in level 3 fair value measurements, which are effective for us on April 1, 2011. The adoption of these standards on January 1, 2010 did not have a material effect on our consolidated financial statements.

     Business Combinations: On April 1, 2009, we adopted two sets of standards affecting business combinations. One set of standards amends the recognition and measurement of identifiable assets and goodwill acquired, liabilities assumed and any noncontrolling interest in the acquiree in a business combination. These standards also provide disclosure requirements to enable users of the financial statements to evaluate the nature and financial effects of the business combination. In addition, adjustments made to valuation allowances on deferred taxes and acquired tax contingencies related to acquisitions made prior to April 1, 2009 fall within the scope of these standards.
     The second set of standards addresses accounting for assets acquired and liabilities assumed that arise from contingencies in a business combination. These standards address application issues raised on the initial recognition and measurement, subsequent measurement and accounting for and disclosure of these assets and liabilities. The adoption of these standards did not have a material effect on our consolidated financial statements; however, it may have an effect on the accounting for any future acquisitions or divestitures.
     Consolidation: On April 1, 2009, we adopted new standards on noncontrolling interests in consolidated financial statements. These standards require reporting entities to present noncontrolling interests in any of their consolidated entities as equity (as opposed to a liability or mezzanine equity) and provide guidance on the accounting for transactions between an entity and noncontrolling interests. This adoption did not have a material effect on our consolidated financial statements; however, these standards may have an effect on any future investments or divestitures of our investments.
     On January 1, 2010, we adopted amended standards that clarify the accounting and disclosure for a decrease in ownership in a subsidiary or an exchange of a group of assets that is a business or nonprofit activity. This adoption did not have a material effect on our consolidated financial statements; however, these standards may affect future divestitures of subsidiaries or groups of assets within its scope.
     Intangibles — Goodwill and Other: On April 1, 2009, we adopted two new standards affecting intangible assets. One of the standards addressed factors that should be considered in developing renewal or extension assumptions used to determine the useful life of a recognized intangible asset.
     The second standard affected accounting for defensive intangible assets, which are acquired assets that an entity does not intend to actively use, but will hold (lock up) to prevent others from obtaining access to them. These standards do not address intangible assets that are used in research and development activities. Neither of these standards had a material effect on our consolidated financial statements.
     Earnings Per Share: On April 1, 2009, we adopted new standards that address whether instruments granted in share-based compensation transactions are participating securities. The new standards conclude that unvested share-based awards that contain nonforfeitable rights to dividends or dividend equivalents (whether paid or unpaid) are participating securities and shall be included in the computation of basic earnings per share pursuant to the two-class method. This adoption did not have a material effect on our consolidated financial statements.
     Investments — Equity Method and Joint Ventures: On April 1, 2009, we adopted new standards on the initial measurement of an equity method investment, testing of the investment for other-than-temporary impairment and accounting for any subsequent equity activities by the investee. This adoption did not have a material effect on our consolidated financial statements.
     Investments — Debt and Equity Securities: On April 1, 2009, we adopted new standards that revise the criteria for recognizing other-than-temporary impairments of debt securities for which changes in fair value are not regularly recognized in earnings and the financial statement presentation of such impairments. The standards also expand and increase the frequency of disclosures related to other-than-temporary impairments of both debt and equity securities. This adoption did not have a material effect on our consolidated financial statements.

     Financial Instruments: On June 30, 2009, we adopted new standards that require disclosures about the fair value of financial instruments for interim and annual reporting periods. These new standards do not require disclosures for earlier periods presented for comparative purposes at initial adoption. This adoption did not have a material effect on our consolidated financial statements, but did expand the disclosures presented. Refer to Financial Note 15, “Financial Instruments and Hedging Activities,” for further discussion.
     Subsequent Events: On June 30, 2009, we adopted new standards that establish general guidance for accounting and disclosures of events that occur after the balance sheet date but before financial statements are issued or are available to be issued. The adoption of these standards require us to evaluate all subsequent events that occur after the balance sheet date through the date and time our financial statements are issued. This adoption did not have a material effect on our consolidated financial statements.
     In February 2010, the FASB amended these standards to remove the requirement for an SEC filer to disclose a date in both issued and revised financial statements. The amended standards clarified the definition of “revised” as being the result of either correction of an error or retrospective application of GAAP. We adopted these amended standards upon their issuance; they did not have a material effect on our consolidated financial statements.
     Equity: On January 1, 2010, we adopted amended standards to clarify the treatment of certain distributions to shareholders that have both stock and cash components. The stock portion of such distributions is considered a share issuance that is reflected in earnings per share prospectively and is not a stock dividend. This adoption did not have a material affect on our consolidated financial statements; however, they may affect any future stock distributions.
     Compensation: On March 31, 2010, we adopted new standards on an employer’s disclosures about plan assets of a defined benefit pension or other postretirement plan. Refer to Financial Note 13, “Pension Benefits,” for the additional disclosure.
     Newly Issued Accounting Pronouncements
     Revenue Recognition: In October 2009, the FASB issued new standards for multiple-deliverable revenue arrangements. These new standards affect the determination of when individual deliverables included in a multiple-element arrangement may be treated as separate units of accounting. In addition, these new standards modify the manner in which the transaction consideration is allocated across separately identified deliverables, eliminate the use of the residual value method of allocating arrangement consideration and require expanded disclosure. These new standards will become effective for us for multiple-element arrangements entered into or materially modified on or after April 1, 2011. Earlier application is permitted with required transition disclosures based on the period of adoption. We are currently evaluating the application date and the effect of these standards on our consolidated financial statements.
     In April 2010, the FASB issued new standards for vendors, who apply the milestone method of revenue recognition to research and development arrangements. These new standards apply to arrangements with payments that are contingent, at inception, upon achieving substantively uncertain future events or circumstances. These new standards are effective on a prospective basis for us for milestones achieved on or after April 1, 2011. Earlier application is permitted. We are currently evaluating the application date and the effect of these standards on our consolidated financial statements.
     Software: In October 2009, the FASB issued amended standards for the accounting for certain revenue arrangements that include software elements. These new standards amend pre-existing software revenue guidance by removing from its scope tangible products that contain both software and non-software components that function together to deliver the product’s functionality. These amended standards will become effective for us for revenue arrangements entered into or materially modified on or after April 1, 2011. Earlier application is permitted with required transition disclosures based on the period of adoption. We are currently evaluating the application date and the effect of these standards on our consolidated financial statements. Both the revenue recognition standards for multiple-element arrangements and these software standards must be adopted in the same period and must use the same transition disclosures.

     Accounting for Transfers of Financial Assets: In December 2009, the FASB issued amended standards on accounting for transfers of financial assets, including securitization transactions, in which entities have continued exposure to risks related to transferred financial assets. These amendments also expand the disclosure requirements for such transactions. These amended standards will become effective for us on April 1, 2010. Based on our existing accounts receivable sales facility agreement, we anticipate that accounts receivable transactions from April 1, 2010, forward may, for U.S. GAAP purposes, be accounted for as secured borrowings rather than asset sales.
     Consolidations: In December 2009, the FASB issued amended standards for consolidation of VIEs primarily related to the determination of the primary beneficiary of the VIE. These amended standards will become effective for us on April 1, 2010. Based on our existing relationships with VIEs, we do not anticipate that these amended standards will have a material affect on our consolidated financial statements upon adoption. However, these amended standards may have an effect on accounting for any changes to the existing relationships or future investments.
2. Business Combinations and Investments
     In 2009, we made the following acquisition:
     On May 21, 2008, we acquired McQueary Brothers Drug Company (“McQueary Brothers”) of Springfield, Missouri for approximately $190 million. McQueary Brothers is a regional distributor of pharmaceutical, health and beauty products to independent and regional chain pharmacies in the Midwestern U.S. This acquisition expanded our existing U.S. pharmaceutical distribution business. The acquisition was funded with cash on hand. Financial results for McQueary Brothers have been included within our Distribution Solutions segment since the date of acquisition.
     The following table summarizes the fair values of the assets acquired and liabilities assumed as of the acquisition date:
         
(In millions)        
 
Accounts receivable
  $ 37  
Inventory
    41  
Goodwill
    126  
Intangible assets
    67  
Other assets
    11  
Accounts payable and other liabilities
    (60 )
Deferred tax liability
    (32 )
 
     
Net assets acquired, less cash and cash equivalents
  $ 190  
 
     During the first quarter of 2010, the acquisition accounting was completed. Approximately $126 million of the purchase price allocation has been assigned to goodwill, which primarily reflects the expected future benefits from synergies to be realized upon integrating the business. Included in the purchase price allocation are acquired identifiable intangibles of $61 million representing a customer relationship with a useful life of 7 years, a trade name of $2 million with a useful life of less than one year and a not-to-compete agreement of $4 million with a useful life of 4 years.
     In 2008, we made the following acquisition:
     On October 29, 2007, we acquired all of the outstanding shares of Oncology Therapeutics Network (“OTN”) of San Francisco, California for approximately $519 million, including the assumption of debt and net of $31 million of cash and cash equivalents acquired from OTN. During the third quarter of 2009, the acquisition accounting was completed. OTN is a U.S. distributor of specialty pharmaceuticals. The acquisition of OTN expanded our existing specialty pharmaceutical distribution business. The acquisition was funded with cash on hand. Financial results for OTN have been included within our Distribution Solutions segment since the date of acquisition.

     Approximately $240 million of the purchase price allocation has been assigned to goodwill, which primarily reflects the expected future benefits from synergies upon integrating the business. Included in the purchase price allocation are acquired identifiable intangibles of $115 million representing customer relationships with a weighted-average life of 9 years, developed technology of $3 million with a weighted-average life of 4 years and trademarks and trade names of $10 million with a weighted-average life of 5 years.
     During the last three years, we also completed a number of other smaller acquisitions and investments within both of our operating segments. Financial results for our business acquisitions have been included in our consolidated financial statements since their respective acquisition dates. Purchase prices for our business acquisitions have been allocated based on estimated fair values at the date of acquisition and for certain recent acquisitions may be subject to change as we continue to evaluate and implement various restructuring initiatives. Goodwill recognized for our business acquisitions is generally not expected to be deductible for tax purposes. Pro forma results of operations for our business acquisitions have not been presented because the effects were not material to the consolidated financial statements on either an individual or an aggregate basis.
3. Share-Based Compensation
     We provide share-based compensation for our employees, officers and non-employee directors, including stock options, an employee stock purchase plan, restricted stock (“RS”), restricted stock units (“RSUs”) and performance-based restricted stock units (“PeRSUs”) (collectively, “share-based awards.”) Most of our share-based awards are granted in the first quarter of each fiscal year.
     Compensation expense for the share-based awards is recognized for the portion of the awards that is ultimately expected to vest. We develop an estimate of the number of share-based awards, which will ultimately vest primarily based on historical experience. The estimated forfeiture rate established upon grant is re-assessed throughout the requisite service period. As required, the forfeiture estimates are adjusted to reflect actual forfeitures when an award vests. The actual forfeitures in future reporting periods could be higher or lower than current estimates. The weighted-average forfeiture rate is approximately 7% at March 31, 2010.
     The compensation expense recognized has been classified in the consolidated statements of operations or capitalized on the consolidated balance sheets in the same manner as cash compensation paid to our employees. There was no material share-based compensation expense capitalized as part of the cost of an asset in 2010, 2009 and 2008.

(1)   This expense was primarily the result of PeRSUs awarded in prior years, which converted to RSUs due to the attainment of goals during the applicable years’ performance period.
 
(2)   Represents estimated compensation expense for PeRSUs that are conditional upon attaining performance objectives during the current year’s performance period.
 
(3)   Income tax expense is computed using the tax rates of applicable tax jurisdictions. Additionally, a portion of pre-tax compensation expense is not tax-deductible.
     Stock Plans
     The 2005 Stock Plan provides our employees, officers and non-employee directors share-based long-term incentives. The 2005 Stock Plan permits the granting of up to 42.5 million shares in the form of stock options, RS, RSUs, PeRSUs and other share-based awards. As of March 31, 2010, 20 million shares remain available for future grant under the 2005 Stock Plan.
     Stock Options
     Stock options are granted at no less than fair market value and those options granted under the 2005 Stock Plan generally have a contractual term of seven years and follow a four-year vesting schedule. Prior to 2005, stock options typically had a contractual term of ten years and vested over a four-year period. We expect option grants in 2010 and future years will have the same general contractual term and vesting schedule as those options granted under the 2005 Stock Plan.
     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 continue to 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 better 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 exercise and other behavior data and reflects the impact of changes in contractual life of current option grants compared to our historical grants.

     RS, RSUs and PeRSUs
     RS and 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 date of grant. The fair value of RS and RSUs under our stock plans is determined by the product of the number of shares that are expected to vest and the grant date market price of the Company’s common stock. The Compensation Committee determines the vesting terms at the time of grant. These awards generally vest in four years. We recognize expense for RS and RSUs with a single vest date on a straight-line basis over the requisite service period. We have elected to expense the grant date fair value of RS and RSUs with only graded vesting and service conditions on a straight-line basis over the requisite service period. RS contains certain restrictions on transferability and may not be transferred until such restrictions lapse.
     Non-employee directors receive an annual grant of up to 5,000 RSUs, which vest immediately and are expensed upon grant. However, issuance of any underlying shares granted prior to the July 2008 Annual Meeting of Stockholders is deferred until the director is no longer performing services for the Company. For those RSUs granted subsequent to July 2008, the director may choose to receive payment immediately or defer receipt of the underlying shares if they meet director stock ownership guidelines. At March 31, 2010, 94,000 RSUs for our directors are vested, but shares have not been issued.
     PeRSUs are RSUs for which the number of RSUs awarded may be conditional upon the attainment of one or more performance objectives over a specified period. PeRSUs are accounted for as variable awards until the performance goals are reached and the grant date is established. The fair value of PeRSUs is determined by the product of the number of shares eligible to be awarded 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 PeRSUs are re-valued 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. For PeRSUs granted prior to 2009 with multiple vest dates, we recognize the fair value expense of these awards on a graded vesting basis over the requisite service period of four years. PeRSUs granted during 2009 and after and the related RSUs (when they are granted) have a single vest date and accordingly, we recognize expense on a straight-line basis over the requisite service period of four years.

     In May 2009, the Compensation Committee approved 2 million PeRSU target share units representing the base number of awards that could be granted, if goals are attained, and would be granted in the first quarter of 2011 (the “2010 PeRSU”). These target share units are not included in the table above as they have not been granted in the form of RSUs. As of March 31, 2010, the total compensation cost, net of estimated forfeitures, related to nonvested 2010 PeRSUs not yet recognized was approximately $146 million, pre-tax (based on the period-end market price of the Company’s common stock) and the weighted-average period over which the cost is expected to be recognized is 3 years.
     Employee Stock Purchase Plan (“ESPP”)
     The Company has an ESPP under which 16 million shares have been authorized for issuance. The ESPP allows eligible employees to purchase shares of our common stock through payroll deductions. The deductions occur over three-month purchase periods and the shares are then purchased at 85% of the market price at the end of each purchase period. Employees are allowed to terminate their participation in the ESPP at any time during the purchase period prior to the purchase of the shares. The 15% discount provided to employees on these shares is included in compensation expense. The shares related to funds outstanding at the end of a quarter are included in the calculation of diluted weighted average shares outstanding. These amounts have not been significant. In 2010, 2009 and 2008, 1 million shares were issued under the ESPP and 3 million shares remain available for issuance at March 31, 2010.

     Our restructuring activities are primarily due to the consolidation of business functions and facilities from newly acquired businesses.
     Restructuring Activities and Asset Impairment — Expenses
     During 2010 and 2009, there were no material restructuring costs incurred.
     During 2008, we incurred $19 million of restructuring expenses, which primarily consisted of:
    $4 million of severance costs associated with the closure of two facilities within our Distribution Solutions segment,
    $1 million and $3 million of severance and asset impairments associated with the integration of OTN within our Distribution Solutions segment, and
    $5 million of severance and exit-related costs and a $4 million asset impairment charge for the write-off of capitalized software costs associated with the termination of a software project within our Technology Solutions segment.

FINANCIAL NOTES (Continued)
     Restructuring Activities — Liabilities Related to Business Combinations
     In connection with our OTN acquisition within our Distribution Solutions segment, to date we recorded a total of $8 million of employee severance costs and $5 million of facility exit costs.
     As of March 31, 2010, the majority of the restructuring accruals of $9 million, which primarily consist of employee severance costs and facility exit and contract termination costs, are anticipated to be disbursed through 2011. Accrued restructuring liabilities are included in other accrued and other noncurrent liabilities in the consolidated balance sheets.
     The majority of past initiatives were completed during 2010. Based on our current existing initiatives, we expect to complete the majority of these activities by the end of 2011. Expenses associated with these initiatives are not anticipated to be material. Approximately 970 employees, consisting primarily of distribution, general and administrative staffs were planned to be terminated as part of our restructuring plans since 2008, of which 891 employees had been terminated as of March 31, 2010. Restructuring expenses are included in cost of sales and operating expenses in our consolidated statements of operations.
     Other Workforce Reduction Charges
     In 2010, 2009 and 2008, we recorded $20 million ($9 million for our Distribution Solutions segment and $11 million for our Technology Solutions segment), $32 million ($7 million for our Distribution Solutions segment and $25 million for our Technology Solutions segment) and $8 million of net charges (for our Technology Solutions segment) associated with various reductions in workforce actions. Other workforce reduction charges also reflected related facility exit costs of $4 million and $3 million in 2010 and 2009 for our Technology Solutions segment. Although these actions do not constitute a restructuring plan, as defined under U.S. GAAP, they do represent independent actions taken from time-to-time, as appropriate.
     Total restructuring and other workforce reduction charges were recorded within our consolidated statements of operations as follows: $5 million, $5 million and $7 million in cost of sales in 2010, 2009 and 2008 and $17 million, $28 million and $20 million within operating expenses.

     In July 2008, our Distribution Solutions segment sold its 42% equity interest in Verispan L.L.C. (“Verispan”), a data analytics company, for a pre-tax gain of $24 million or $14 million after-tax.

     We evaluate our investments for impairment when events or changes in circumstances indicate that the carrying values of such investments may have experienced an other-than-temporary decline in value. During the fourth quarter of 2009, we determined that the fair value of our interest in Parata Systems, LLC (“Parata”) was lower than its carrying value and that such impairment was other-than-temporary. Fair value was determined using a discounted cash flow analysis based on estimated future results and market capitalization rates. We determined the impairment was other-than-temporary based on our assessment of all relevant factors including deterioration in the investee’s financial condition and weak market conditions. As a result, we recorded a pre-tax impairment of $58 million ($55 million after-tax) on this investment, which is recorded within other income, net in the consolidated statements of operations. Our investment in Parata is accounted for under the equity method of accounting within our Distribution Solutions segment.
     During the fourth quarter of 2009, we also recorded a pre-tax impairment of $5 million ($5 million after-tax) on another equity-held investment within our Distribution Solutions segment.

     In 2009, we recorded a total income tax expense of $241 million, which included an income tax benefit of $182 million related to the Average Wholesale Price (“AWP”) litigation charge described in more detail in Financial Note 18, “Other Commitments and Contingent Liabilities.” The tax benefit could change in the future depending on the resolution of the pending and expected claims.
     In 2009, current income tax expense included $111 million of net income tax benefits for discrete items of which, $87 million represents a non-cash benefit. These benefits primarily relate to the recognition of previously unrecognized tax benefits and related accrued interest. The recognition of these discrete items was primarily due to the lapsing of the statutes of limitations.

     In 2008, the U.S. Internal Revenue Service (“IRS”) began its examination of our fiscal years 2003 through 2006. In 2009 and 2010, we received assessments from the Canada Revenue Agency (“CRA”) for a total of $62 million related to transfer pricing for 2003, 2004 and 2005. We paid the CRA assessments to stop the accrual of interest. We have appealed the assessment for 2003 and have filed a notice of objection for 2004 and 2005. We believe that we have adequately provided for any potential adverse results. In nearly all jurisdictions, the tax years prior to 2003 are no longer subject to examination. We believe that we have made adequate provision for all remaining income tax uncertainties.
     In 2008, the IRS completed an examination of our consolidated income tax returns for 2000 to 2002 resulting in a signed Revenue Agent Report (“RAR”), which was subsequently approved by the Joint Committee on Taxation. The IRS and the Company agreed to certain adjustments, primarily related to transfer pricing and income tax credits. As a result of the approved RAR, we recognized approximately $25 million of net federal and state income tax benefits in 2008.
     Significant judgments and estimates are required in determining the consolidated income tax provision. Although our major taxing jurisdictions are the U.S. and Canada, we are subject to income taxes in numerous foreign jurisdictions. Annually, we file a federal consolidated income tax return with the IRS and over 1,200 returns with various state and foreign jurisdictions. Our income tax expense, deferred tax assets and liabilities reflect management’s best assessment of estimated current and future taxes to be paid.
     The reconciliation between our effective tax rate on income from continuing operations and statutory tax rate is as follows:

     At March 31, 2010, undistributed earnings of our foreign operations totaling $2.3 billion were considered to be permanently reinvested. No deferred tax liability has been recognized for the remittance of such earnings to the U.S. since it is our intention to utilize those earnings in the foreign operations as well as to fund certain research and development activities for an indefinite period of time, or to repatriate such earnings when it is tax efficient to do so. The determination of the amount of deferred taxes on these earnings is not practicable because the computation would depend on a number of factors that cannot be known until a decision to repatriate the earnings is made.

     We have federal, state and foreign income tax net operating loss carryforwards of $122 million, $2.8 billion and $201 million. The federal and state net operating losses will expire at various dates from 2011 through 2030. Substantially all of our foreign net operating losses have indefinite lives. We believe that it is more likely than not that the benefit from certain federal, state and foreign net operating loss carryforwards may not be realized. In recognition of this risk, we have provided valuation allowances of $15 million and $45 million on the deferred tax assets relating to these state and foreign net operating loss carryforwards. We also have federal and state capital loss carryforwards of $40 million and $36 million. The federal and state net capital losses will expire at various dates from 2012 through 2015. We believe that it is more likely than not that the benefit from these capital loss carryforwards may not be realized. In recognition of this risk, we have provided valuation allowances of $14 million and $2 million.
     We also have domestic income tax credit carryforwards of $222 million which are primarily alternative minimum tax credit carryforwards that have an indefinite life. However, we believe that it is more likely than not that the benefit from certain state tax credits of $2 million may not be realized. In recognition of this risk, we have provided a valuation allowance of $2 million. In addition, we have Canadian research and development credit carryforwards of $14 million. The Canadian research and development credits will expire at various dates from 2018 to 2030.

  $ 619     $ 526     $ 496  
 
     Of the total $619 million in unrecognized tax benefits at March 31, 2010, $396 million would reduce income tax expense and the effective tax rate if recognized. During the next twelve months, it is reasonably possible that audit resolutions and the expiration of statutes of limitations could potentially reduce our unrecognized tax benefits by up to $23 million. However, this amount may change because we continue to have ongoing negotiations with various taxing authorities throughout the year.
     We continue to report interest and penalties on tax deficiencies as income tax expense. At March 31, 2010, before any tax benefits, our accrued interest on unrecognized tax benefits amounted to $118 million. We recognized an income tax expense of $17 million, before any tax effect, related to interest in our consolidated statements of operations during 2010. We have no material amounts accrued for penalties.
7. Discontinued Operations
     No charges for discontinued operations were incurred during 2010 and 2009. In 2008, discontinued operations included $1 million from the Company’s Acute Care business, which was sold in 2007.
8. Earnings Per Common Share
     Basic earnings per common share are computed by dividing net income by the weighted average number of common shares outstanding during the reporting period. Diluted earnings per common share are computed similar to basic earnings per common share except that it reflects the potential dilution that could occur if dilutive securities or other obligations to issue common stock were exercised or converted into common stock.

Long-Term Debt
     On February 12, 2009, the Company issued 6.50% notes due February 15, 2014 (the “2014 Notes”) in an aggregate principal amount of $350 million and 7.50% notes due February 15, 2019 (the “2019 Notes”) in an aggregate principal amount of $350 million. Interest is payable on February 15 and August 15 of each year beginning on August 15, 2009. The 2014 Notes will mature on February 15, 2014 and the 2019 Notes will mature on February 15, 2019. The Company utilized net proceeds, after discounts and offering expenses, of $693 million from the issuance of the 2014 Notes and 2019 Notes for general corporate purposes.
     On March 5, 2007, we issued 5.25% notes due March 1, 2013 (the “2013 Notes”) in an aggregate principal amount of $500 million and 5.70% notes due March 1, 2017 (the “2017 Notes,” collectively with the 2013 Notes, 2014 Notes, 2019 Notes, the “Notes” and each note constitutes a “Series”) in an aggregate principal amount of $500 million for which interest is payable on March 1 and September 1 of each year. The 2013 Notes will mature on March 1, 2013 and the 2017 Notes will mature on March 1, 2017. We utilized net proceeds, after discounts and offering expenses, of $990 million from the issuance of the 2013 Notes and 2017 Notes, together with cash on hand, to repay outstanding interim indebtedness related to our January 2007 acquisition of Per-Se.
     Each Series constitutes an unsecured and unsubordinated obligation of the Company and ranks equally with all of the Company’s existing and future unsecured and unsubordinated indebtedness outstanding from time-to-time. Each Series is governed by an indenture common to all Notes and an officers’ certificate specifying certain terms of each Series.
     Upon 30 days notice to holders of a Series, we may redeem that Series at any time prior to maturity, in whole or in part, for cash at redemption prices that include accrued and unpaid interest and a make-whole premium, as specified in the indenture and officers’ certificate relating to that Series. In the event of the occurrence of both (1) a change of control of the Company and (2) a downgrade of a Series below an investment grade rating by each of Fitch Ratings, Moody’s Investors Service, Inc. and Standard & Poor’s Ratings Services within a specified period, an offer will be made to purchase that Series from the holders at a price in cash equal to 101% of the then outstanding principal amount of that Series, plus accrued and unpaid interest to, but not including, the date of repurchase. The indenture and the related officers’ certificate for each Series, subject to the exceptions and in compliance with the conditions as applicable, specify that we may not incur liens, enter into sale and leaseback transactions or consolidate, merge or sell all or substantially all of our assets. The indentures also contain customary events and default provisions.

     In March 2010, we repaid our $215 million 9.13% Series C Senior Notes which had matured.
Accounts Receivable Sales Facility
     In May 2009, we renewed our accounts receivable sales facility for an additional one year period under terms similar to those previously in place. The renewed facility will expire in mid-May 2010. Based on our existing accounts receivable sales facility agreement, we anticipate that activity under this facility may, for U.S. GAAP purposes, be considered as a secured borrowing rather than a sale under accounting standards that will become effective for us on April 1, 2010. We anticipate renewing this facility before its expiration. The aggregate commitment of the purchasers under this facility is $1.1 billion, although from time-to-time, the available amount may be less than that amount based on concentration limits and receivable eligibility requirements.
     Information regarding our outstanding balances related to our interests in accounts receivable sold or qualifying receivables retained is as follows:

     The delinquency ratio for the qualifying receivables represented less than 1% of the total qualifying receivables as of March 31, 2010 and March 31, 2009.
Revolving Credit Facility
     We have a syndicated $1.3 billion five-year senior unsecured revolving credit facility, which expires in June 2012. Borrowings under this credit facility bear interest based upon either a Prime rate or the London Interbank Offering Rate. There were no borrowings under this facility in 2010 and $279 million for 2009. As of March 31, 2010 and 2009, there were no amounts outstanding under this facility.
Commercial Paper
     We issued and repaid commercial paper of nil and approximately $3.3 billion and $260 million in 2010, 2009 and 2008. There were no commercial paper issuances outstanding at March 31, 2010 and 2009.
Debt Covenants
     Our various borrowing facilities and long-term debt are subject to certain covenants. Our principal debt covenant is our debt to capital ratio under our unsecured revolving credit facility, which cannot exceed 56.5%. If we exceed this ratio, repayment of debt outstanding under the revolving credit facility could be accelerated. As of March 31, 2010, this ratio was 23.4% and we were in compliance with our other financial covenants.

13. Pension Benefits
     We maintain a number of qualified and nonqualified defined pension benefit plans and defined contribution plans for eligible employees.
Defined Pension Benefit Plans
     Eligible U.S. employees who were employed by the Company prior to December 31, 1996 are covered under the Company-sponsored defined benefit retirement plan. In 1997, we amended this plan to freeze all plan benefits based on each employee’s plan compensation and creditable service accrued to that date. The Company has made no annual contributions since this plan was frozen. The benefits for this defined benefit retirement plan are based primarily on age of employees at date of retirement, years of service and employees’ pay during the five years prior to retirement. We also have defined benefit pension plans for eligible Canadian and United Kingdom employees as well as an unfunded nonqualified supplemental defined benefit plan for certain U.S. executives. We also assumed a frozen qualified defined benefit plan through our acquisition of Per-Se Technologies, Inc. (“Per-Se”) in 2007. The Per-Se plan was merged into our retirement plan in 2008. We adopted the measurement provisions of new accounting standards for benefit provisions in the fourth quarter of 2009. As required, our defined benefit plan assets and obligations are now measured as of the Company’s fiscal year-end. We previously performed this measurement at December 31.
     The net periodic expense for our pension plans is as follows:
                         
    Years Ended March 31,
(In millions)   2010   2009   2008

Settlement charges and other
          1       4  
     
Net periodic pension expense
  $ 40     $ 11     $ 14  
 
     The projected unit credit method is utilized in measuring net periodic pension expense over the employees’ service life for the U.S. pension plans. Unrecognized actuarial losses exceeding 10% of the greater of the projected benefit obligation or the market value of assets are amortized straight-line over the average remaining future service periods.

(2)   The unfunded status of our plans at March 31, 2010 and 2009 was primarily due to the decrease in the fair value of our plan assets as a result of the volatility in the financial markets. The 2010 funded status also reflects the unfavorable effect from the reduction in discount rates.
     The accumulated benefit obligations for our pension plans were $574 million at March 31, 2010 and $441 million at March 31, 2009.

     We expect to amortize $1 million of prior service cost and $26 million of actuarial loss for the pension plans from stockholders’ equity to pension expense in 2011. Comparable 2010 amounts were $2 million and $23 million.
     Projected benefit obligations relating to our unfunded U.S. plans were $137 million and $110 million at March 31, 2010 and 2009. Pension obligations are funded based on the recommendations of independent actuaries.
     Expected benefit payments for our pension plans are as follows: $31 million, $36 million, $39 million, $31 million and $126 million for 2011 to 2015 and $188 million for 2016 through 2020. 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 pension plans are $7 million for 2011.
     Weighted-average assumptions used to estimate the net periodic pension expense and the actuarial present value of benefit obligations were as follows:
                         
    2010   2009   2008
 
Net periodic pension expense

    3.75       3.93       4.01  
 
     Our U.S. defined benefit pension plan liabilities are valued using a discount rate based on a yield curve developed from a portfolio of high quality corporate bonds rated AA or better whose maturities are aligned with the expected benefit payments of our plans. For March 31, 2010, we used a weighted average discount rate of 5.29%, which represents a decrease of 266 basis points from our 2009 weighted-average discount rate of 7.95%.

     Plan Assets
     Investment Strategy: The overall objective for McKesson’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 plan assets are 59% equity securities, 33% fixed income securities and 8% to all other types of investments including cash and cash equivalents. Equity securities include primarily exchange-traded common stock and preferred stock of companies from diversified industries. Fixed income securities include corporate bonds of companies from diversified industries, government securities, mortgage-backed securities, asset-backed securities and other. Other types of investments include investments in real estate and venture capital funds, hedge funds and cash and cash equivalents. Portions of the equity, fixed income and cash and cash-equivalent investments are held in commingled funds.
     We develop our expected long-term rate of return assumption based on the historical experience of our portfolio and review of projected performance by asset class of broad, publicly traded equity and fixed-income indices. Our target asset allocation was determined based on the risk tolerance characteristics of the plans and at times may be adjusted to achieve our overall investment objectives.
     Fair Value Measurements: The following table represents our pension plan assets as of March 31, 2010, using the fair value hierarchy by asset class. The fair value hierarchy has three levels based on the reliability of the inputs used to determine fair value. Level 1 refers to fair values determined based on unadjusted quoted prices in active markets for identical assets. Level 2 refers to fair values estimated using significant other observable inputs and Level 3 includes fair values estimated using significant non-observable inputs.
