patients, and controls its expenditures by purchasing products through public tenders, collective purchasing, regulating prices, setting reference prices in public tenders or limiting reimbursement or patient access to certain products.

Intellectual Property

Patents and other proprietary rights are essential to Baxter’s business. Baxter relies on patents, trademarks, copyrights, trade secrets, know-how and confidentiality agreements to develop, maintain and strengthen its competitive position. Baxter owns a number of patents and trademarks throughout the world and has entered into license arrangements relating to various third-party patents and technologies. Products manufactured by Baxter are sold primarily under its own trademarks and trade names. Some products distributed by the company are sold under the company’s trade names, while others are sold under trade names owned by its suppliers or partners. Trade secret protection of unpatented confidential and proprietary information is also important to Baxter. The company maintains certain details about its processes, products and technology as trade secrets and generally requires employees, consultants, and business partners to enter into confidentiality agreements. These agreements may be breached and Baxter may not have adequate remedies for any breach. In addition, Baxter’s trade secrets may otherwise become known or be independently discovered by competitors. To the extent that Baxter’s employees, consultants, and business partners use intellectual property owned by others in their work for the company, disputes may arise as to the rights in related or resulting know-how and inventions.

Baxter’s policy is to protect its products and technology through patents and trademarks on a worldwide basis. This protection is sought in a manner that balances the cost of such protection against obtaining the greatest value for the company. Baxter also recognizes the need to promote the enforcement of its patents and trademarks and takes commercially reasonable steps to enforce its patents and trademarks around the world against potential infringers, including judicial or administrative action where appropriate.

Baxter operates in an industry susceptible to significant patent litigation. At any given time, the company is involved as either a plaintiff or defendant in a number of patent infringement and other intellectual property-related actions. Such litigation can result in significant royalty or other payments or result in injunctions that can prevent the sale of products. For more information on patent and other litigation, see Note 16 in Item 8 of this Annual Report on Form 10-K.

Research and Development

Baxter’s investment in research and development (R&D), consistent with the company’s portfolio optimization and capital allocation strategies, helps fuel its future growth and its ability to remain competitive in each of its product categories. Accordingly, Baxter continues to focus its investment on select R&D programs to enhance future growth through clinical differentiation. Expenditures for Baxter’s R&D activities were $617 million in 2017, $647 million in 2016, and $603 million in 2015. These expenditures include costs associated with R&D activities performed at the company’s R&D centers located around the world, which include facilities in Belgium, Sweden, Italy, Germany, China, Japan and the United States, as well as in-licensing, milestone and reimbursement payments made to partners for R&D work performed at non-Baxter locations.

For more information on the company’s R&D activities, refer to the discussion under the caption entitled “Strategic Objectives” in Item 7 of this Annual Report on Form 10-K.

Quality Management

Baxter’s continued success depends upon the quality of its products. Quality management plays an essential role in determining and meeting customer requirements, preventing defects, facilitating continuous improvement of the company’s processes, products and services, and assuring the safety and efficacy of the company’s products. Baxter’s quality system enables the design, development, manufacturing, packaging, sterilization, handling, distribution and labeling of the company’s products to ensure they conform to customer requirements. In order to continually improve the effectiveness and efficiency of the quality system, various measurements, monitoring and analysis methods such as management reviews and internal, external and vendor audits are employed at local and central levels.

Each product that Baxter markets is required to meet specific quality standards, both in packaging and in product integrity and quality. If any of those is determined to be compromised at any time, Baxter endeavors to take corrective and preventive actions designed to ensure compliance with regulatory requirements and to meet customer expectations. For more information on corrective actions taken by Baxter, refer to the discussion under the caption entitled “Certain Regulatory Matters” in Item 7 of this Annual Report on Form ‑10-K.

Government Regulation

The operations of Baxter and many of the products manufactured or sold by the company are subject to extensive regulation by numerous government agencies, both within and outside the United States. The Food and Drug Administration (FDA) in the United States, the European Medicines Agency (EMA) in Europe, the China Food and Drug Administration (CFDA) in China and other government agencies inside and outside of the United States, administer requirements covering the testing, safety, effectiveness, manufacturing, labeling, promotion and advertising, distribution and post-market surveillance of Baxter’s products. The company must obtain specific approval from FDA and non-U.S. regulatory authorities before it can market and sell most of its products in a particular country. Even after the company obtains regulatory approval to market a product, the product and the company’s manufacturing processes and quality systems are subject to continued review by FDA and other regulatory authorities globally. State agencies in the United States also regulate the facilities, operations, employees, products and services of the company within their respective states. The company and its facilities are subject to periodic inspections and possible administrative and legal actions by FDA and other regulatory agencies inside and outside the United States. Such actions may include warning letters, product recalls or seizures, monetary sanctions, injunctions to halt manufacture and distribution of products, civil or criminal sanctions, refusal of a government to grant approvals or licenses, restrictions on operations or withdrawal of existing approvals and licenses. As situations require, the company takes steps to ensure safety and efficacy of its products, such as removing products found not to meet applicable requirements from the market and improving the effectiveness of quality systems. For more information on compliance actions taken by the company, refer to the discussion under the caption entitled “Certain Regulatory Matters” in Item 7 of this Annual Report on Form 10-K.

The company is also subject to various laws inside and outside the United States concerning its relationships with healthcare professionals and government officials, price reporting and regulation, the promotion, sales and marketing of its products and services, the importation and exportation of products, the operation of its facilities and distribution of products. In the United States, the company is subject to the oversight of FDA, Office of the Inspector General within the Department of Health and Human Services (OIG), the Center for Medicare/Medicaid Services (CMS), the Department of Justice (DOJ), Environmental Protection Agency, Department of Defense and Customs and Border Protection in addition to others. The company supplies products and services to healthcare providers that are reimbursed by federally funded programs such as Medicare. As a result, the company’s activities are subject to regulation by CMS and enforcement by OIG and DOJ. In each jurisdiction outside the United States, the company’s activities are subject to regulation by government agencies including the EMA in Europe, CFDA in China and other agencies in other jurisdictions. Many of the agencies enforcing these laws have increased their enforcement activities with respect to healthcare companies in recent years. These actions appear to be part of a general trend toward increased enforcement activity globally.

Environmental policies of the company require compliance with all applicable environmental regulations and contemplate, among other things, appropriate capital expenditures for environmental protection.

Separation of Baxalta

On July 1, 2015, Baxter completed the distribution of approximately 80.5% of the outstanding common stock of  Baxalta to Baxter shareholders (the Distribution). The Distribution was made to Baxter’s shareholders of record as of the close of business on June 17, 2015 (the Record Date), who received one share of Baxalta common stock for each Baxter common share held as of the Record Date. As a result of the distribution, Baxalta became an independent public company.

In 2016, Baxter disposed of its remaining 19.5% interest in Baxalta through a series of transactions including debt-for-equity exchanges, an equity-for-equity exchange and a contribution to its U.S. pension plan. As a result of these transactions, the company extinguished approximately $3.65 billion in company indebtedness, repurchased 11,526,638 Baxter shares and contributed 17,145,570 Baxalta shares to its U.S. pension plan. On June 3, 2016, Baxalta became a wholly-owned subsidiary of Shire plc (Shire).

The local separation of Baxalta’s business in certain countries outside the United States did not occur prior to the distribution date due to regulatory requirements, the need to obtain consents from local governmental authorities and other business reasons. Separation of the remaining three countries has occurred as of December 31, 2017.

As a result of the separation, the consolidated statements of income, consolidated balance sheets, consolidated statements of cash flow, and related financial information reflect Baxalta’s operations, assets and liabilities, and cash flows as discontinued operations for all periods presented.

Refer to Note 2 in Item 8 of this Annual Report on Form 10-K for additional information regarding the separation of Baxalta.

Employees

As of December 31, 2017, Baxter employed approximately 47,000 people.

Item 1A.Risk Factors.

In addition to the other information in this Annual Report on Form 10-K, stockholders or prospective investors should carefully consider the following risk factors. If any of the events described below occurs, our business, financial condition, results of operations, future growth prospects and stock price could suffer.

We may not achieve our long-term financial improvement goals.

We have been implementing plans to enhance profitability and returns for our stockholders. These plans include the achievement of certain financial goals (including improved operating margin and earnings per share) in 2018 and beyond. While we are continuing to refine these goals, our plan contemplates significant margin expansion over our long-range plan, which runs through 2020. We have identified certain key strategies to help achieve these targets. These strategies include optimizing our core product portfolio globally, driving operational excellence through the realignment of our cost structure and various restructuring activities and maximizing the value derived from the allocation of our capital.

As part of these strategies, we continue to evaluate the performance of all of our businesses and may sell or acquire a business or product line or exit a particular market. We are also evaluating our corporate and commercial infrastructure in the interest of streamlining costs while maintaining our commitment to quality and safety. Future divestitures may result in significant write-offs, including those related to goodwill and other intangible assets. Future acquisitions may fail to achieve the desired financial results (including return on investment) and synergies and may not provide the desired market access. The restructuring of our operations may not generate targeted savings or may cause unexpected disruptions to our business. As a result, we may not achieve our targeted financial results, which could have a material adverse effect on our business, financial condition or results of operations.

If we are unable to successfully introduce new products or fail to keep pace with advances in technology, our business, financial condition and results of operations could be adversely affected.

We need to successfully introduce new products to achieve our strategic business objectives. Product development requires substantial investment and there is inherent risk in the R&D process. A successful product development process depends on many factors, including our ability to properly anticipate and satisfy customer needs, adapt to new technologies, obtain regulatory approvals on a timely basis, demonstrate satisfactory clinical results, manufacture products in an economical and timely manner and differentiate our products from those of our competitors. If we cannot successfully introduce new products or adapt to changing technologies, our products may become obsolete and our revenue and profitability could suffer.

Issues with product supply or quality could have an adverse effect upon our business, subject us to regulatory actions, cause a loss of customer confidence in us or our products, among other negative consequences.

Our success depends upon the availability and quality of our products. The medical products industry is competitive and subject to complex market dynamics and varying demand levels. These levels vary in response to macro-economic conditions, regulatory requirements (including the availability of private or public reimbursement), seasonality, natural disasters, epidemics and other matters. Additionally the development of new or enhanced products involves a lengthy regulatory process and is capital intensive. As a result, our ability to match our production levels and capacity to market demand is imprecise and may result in a failure to meet market demand or satisfy customer requirements for our products or, alternatively, an oversupply of inventory. Failure to meet market demand may result in customers transitioning to available competitive products, loss of market share, negative publicity, reputational damage, loss of customer confidence or other negative consequences (including a decline in stock price). In the event of an oversupply, we may be forced to lower our prices or record asset impairment charges or take other action which may adversely affect our business, financial condition and results of operations.

Additionally, quality management plays an essential role in determining and meeting customer requirements, preventing defects, improving the company’s products and services and assuring the safety and efficacy of our products. Our future success depends on our ability to maintain and continuously improve our quality management program. While we have a quality system that covers the

lifecycle of our products, quality and safety issues may occur with respect to any of our products. A quality or safety issue may result in adverse inspection reports, voluntary or official action indicated, warning letters, import bans, product recalls (either voluntary or required by the FDA or similar governmental authorities in other countries) or seizures, monetary sanctions, injunctions to halt manufacture and distribution of products, civil or criminal sanctions, costly litigation, refusal of a government to grant approvals and licenses, restrictions on operations or withdrawal of existing approvals and licenses. An inability to address a quality or safety issue in an effective and timely manner may also cause negative publicity, a loss of customer confidence in us or our current or future products, which may result in the loss of sales and difficulty in successfully launching new products. Additionally, Baxter has made and continues to make significant investments in assets, including inventory and property, plant and equipment, which relate to potential new products or modifications to existing products. Product quality or safety issues may restrict the company from being able to realize the expected returns from these investments, potentially resulting in asset impairments in the future.

Unaffiliated third party suppliers provide a number of goods and services to our R&D, clinical and manufacturing organizations. Third party suppliers are required to comply with our quality standards. Failure of a third party supplier to provide compliant raw materials or supplies could result in delays, service interruptions or other quality related issues that may negatively impact our business results.

For more information on regulatory matters currently affecting us, refer to the discussion under the caption entitled “Certain Regulatory Matters” in Item 7 of this Annual Report on Form 10-K.

If we are unable to obtain sufficient components or raw materials on a timely basis or for a cost-effective price or if we experience other manufacturing or supply difficulties, our business and results of operations may be adversely affected.

The manufacture of our products requires, among other things, the timely supply or delivery of sufficient amounts of quality components and materials. We manufacture our products in approximately 50 manufacturing facilities around the world. We acquire our components, materials and other requirements for manufacturing from many suppliers and vendors in various countries, including sometimes from ourselves for self-supplied requirements. We endeavor, either alone or working closely with our suppliers, to ensure the continuity of our inputs and supplies but we cannot guarantee these efforts will always be successful. Further, while efforts are made to diversify certain of our sources of components and materials, in certain instances there is only a sole source or supplier with no alternatives yet identified. For most of our components and materials for which a single source or supplier is used, alternative sources or suppliers may exist, but we have made a strategic determination to use the single source or supplier. Although we do carry strategic inventory and maintain insurance to help mitigate the potential risk related to any related supply disruption, there can be no assurance that such measures will be sufficient or effective. A reduction or interruption in supply and an inability to quickly develop acceptable alternative sources for such supply, could adversely affect our ability to manufacture and distribute our products in a timely or cost-effective manner, and our ability to make product sales.  Additionally, volatility in our costs of energy, transportation/freight, components, raw materials and other supply, manufacturing and distribution costs could adversely affect our results of operations. Climate change (including laws or regulations passed in response thereto) could increase our costs, in particular our costs of supply, energy and transportation/freight. Material or sustained increases in the price of oil could have an adverse impact on the cost of many of the plastic materials we use to make and package our products, as well as our transportation/freight costs. These outcomes may in turn result in customers transitioning to available competitive products, loss of market share, negative publicity, reputational damage, loss of customer confidence or other negative consequences (including a decline in stock price).

Many of our products are difficult to manufacture. This is due to the complex nature of manufacturing pharmaceuticals, including biologics, and devices, as well as the strict regulatory regime governing our manufacturing operations. Variations in the manufacturing process may result in production failures which could lead to launch delays, product shortage, unanticipated costs, lost revenues and damage to our reputation. A failure to identify and address manufacturing problems prior to the release of products to our customers may also result in a quality or safety issue of the type discussed above.

Some of our products are manufactured at a single manufacturing facility or stored at a single storage site. Loss or damage to a manufacturing facility or storage site due to a natural disaster or otherwise could adversely affect our ability to manufacture sufficient quantities of key products or otherwise deliver products to meet customer demand or contractual requirements which may result in a loss of revenue and other adverse business consequences (including those identified in the paragraph above). Because of the time required to approve and license a manufacturing facility, a third party manufacturer may not be available on a timely basis (if at all) to replace production capacity in the event we lose manufacturing capacity or products are otherwise unavailable due to natural disaster, regulatory action or otherwise.

We are increasingly dependent on information technology systems and subject to privacy and security laws, and our systems and infrastructure face certain risks, including from cyber security breaches and data leakage.

We increasingly rely upon technology systems and infrastructure, including support provided by our partners and third parties, to support our business, our products and our customers.  For example, we routinely rely on our technology systems and infrastructure to aid us in the collection, use, storage and transfer, disclosure and other processing of voluminous amounts of data (including confidential, business, personal and other sensitive information).    We also rely on systems for manufacturing, customer orders, shipping, regulatory compliance and various other matters. Certain of our products collect data regarding patients and their therapy and some connect to our systems for maintenance and other purposes.

The increasing use and evolution of technology, including cloud-based computing, and reliance on third parties creates additional opportunities for the unintentional, intentional and/or unauthorized exposure, dissemination and/or destruction of confidential information stored in our technology systems, infrastructure and products. Our products, devices, computer systems, servers and other technology systems (and those of third parties that we use) are vulnerable to breakdown, interruption, cyber and other security attacks, system malfunction, unauthorized access and other events.  Security threats, including cyber and other attacks are becoming increasingly sophisticated, frequent, and adaptive. Any such vulnerability could compromise our technology systems and infrastructure and could expose personal and/or proprietary information (including sensitive personal information) to unauthorized third parties and/or cause permanent loss of such data.  In addition to loss of data, unauthorized access to or interference with our products that utilize cloud-based computing or otherwise send and receive data may cause product functionality issues that may result in risk to patient safety, field actions and/or product recalls. While we have invested in the protection of data and information technology, there can be no assurance that our efforts will prevent breakdowns, breaches in our systems or other incidents or ensure compliance with all applicable security and privacy laws, regulations and standards.  Such breakdowns can lead to regulatory fines and penalties, business disruption, reputational harm, financial loss as well as other damages.  We could also suffer strained relationships with customers and business partners, increased costs (for security measures, remediation or otherwise), litigation (including class actions and stockholder derivative actions) or other negative consequences (including a decline in stock price) from breaches, cyber and other security attacks, industrial espionage, ransomware, email or phishing scams, malware or other cyber incidents, which may compromise our system infrastructure or lead to data leakage, either internally or at our third-party providers or other business partners.  While we have invested in the protection of data and information technology and in related training, there can be no assurance that our efforts will prevent significant breakdowns, attacks, breaches in our systems or other cyber incidents or ensure compliance with all applicable security and privacy laws, regulations and standards, including with respect to third-party service providers that utilize sensitive personal information, including protected health information (PHI), on our behalf.

Additionally, the legal and regulatory environment surrounding information security and privacy is increasingly demanding, with the imposition of new and changing requirements across businesses. We are required to comply with increasingly complex and changing legal and regulatory requirements that govern the collection, use, storage, security, transfer, disclosure and other processing of personal data, including The Health Insurance Portability and Accountability Act, The Health Information Technology for Economic and Clinical Health Act and the European Union’s General Data Protection Regulation (GDPR).  In May 2018, the GDPR will supersede current European Union data protection legislation, impose more stringent European Union data protection requirements, and provide for greater penalties for noncompliance.  We or our third-party providers and business partners may also be subjected to audits or investigations by one or more domestic or foreign government agencies relating to compliance with information security and privacy laws and regulations.

In addition, significant implementation issues may arise as we continue to consolidate and outsource certain computer operations and application support activities. We also face all of the same risks listed above and other heightened risks when acquiring a company, in particular if we need to transition or implement certain processes or controls with the acquired company.

We are subject to a number of existing laws and regulations, non-compliance with which could adversely affect our business, financial condition and results of operations, and we are susceptible to a changing regulatory environment.

As a participant in the healthcare industry, our operations and products, and those of our customers, are regulated by numerous government agencies, both inside and outside the United States. The impact of this on us is direct to the extent we are subject to these laws and regulations, and indirect in that in a number of situations, even though we may not be directly regulated by specific healthcare laws and regulations, our products must be capable of being used by our customers in a manner that complies with those laws and regulations.

The manufacture, distribution, marketing and use of our products are subject to extensive regulation and scrutiny by FDA and other regulatory authorities globally. Any new product must undergo lengthy and rigorous testing and other extensive, costly and time-consuming procedures mandated by FDA and foreign regulatory authorities. The same testing and procedures sometimes apply to

current products that are up for authorization renewal or are subject to changes in law or regulation (for example certain of our medical devices will have to comply with the new European Union Medical Device Regulation). Changes to current products may be subject to vigorous review, including additional 510(k) and other regulatory submissions, and approvals are not certain. Our facilities must be approved and licensed prior to production and remain subject to inspection from time to time thereafter. Failure to comply with the requirements of FDA or other regulatory authorities, including a failed inspection or a failure in our adverse event reporting system, could result in adverse inspection reports, voluntary or official action indicated, warning letters, import bans, product recalls or seizures, monetary sanctions, injunctions to halt the manufacture and distribution of products, civil or criminal sanctions, refusal of a government to grant approvals or licenses, restrictions on operations or withdrawal of existing approvals and licenses. Any of these actions could cause a loss of customer confidence in us and our products, which could adversely affect our sales. The requirements of regulatory authorities, including interpretative guidance, are subject to change and compliance with additional or changing requirements or interpretative guidance may subject the company to further review, result in product launch delays or otherwise increase our costs. For information on current regulatory issues affecting us, please refer to the caption entitled “Certain Regulatory Matters” in Item 7 of this Annual Report on Form 10-K. In connection with these issues, there can be no assurance that additional costs or civil and criminal penalties will not be incurred, that additional regulatory actions with respect to the company will not occur, that the company will not face civil claims for damages from purchasers or users, that substantial additional charges or significant asset impairments may not be required, that sales of other products may not be adversely affected, or that additional regulation will not be introduced that may adversely affect the company’s operations and consolidated financial statements.

The sales, marketing and pricing of products and relationships that pharmaceutical and medical device companies have with healthcare providers are under increased scrutiny by federal, state and foreign government agencies. Compliance with the Anti-Kickback Statute, False Claims Act, Food, Drug and Cosmetic Act (including as these laws relate to off-label promotion of products) and other healthcare related laws, as well as competition, data and patient privacy and export and import laws, is under increased focus by the agencies charged with overseeing such activities, including FDA, OIG, DOJ and the Federal Trade Commission. The DOJ and the Securities and Exchange Commission have also increased their focus on the enforcement of the U.S. Foreign Corrupt Practices Act (FCPA), particularly as it relates to the conduct of pharmaceutical and medical product companies. The FCPA and similar anti-bribery laws generally prohibit companies and their employees, contractors or agents from making improper payments to government officials for the purpose of obtaining or retaining business. Healthcare professionals in many countries are employed by the government and consequently may be considered government officials. Foreign governments have also increased their scrutiny of pharmaceutical and medical product companies’ sales and marketing activities and relationships with healthcare providers and competitive practices generally. The laws and standards governing the promotion, sale and reimbursement of our products and those governing our relationships with healthcare providers and governments, including the Sunshine Act enacted under the Patient Protection and Affordable Care Act (as amended, the PPACA), can be complicated, are subject to frequent change and may be violated unknowingly.

Additionally, the U.S. Department of the Treasury’s Office of Foreign Control and the Bureau of Industry and Security at the U.S. Department of Commerce administer laws and regulations that restrict U.S. persons and, in some instances, non-U.S. persons, in conducting activities, transacting business or making investments in certain countries, governments, entities and individuals subject to U.S. economic sanctions. From time to time, certain of our subsidiaries have limited business dealings in countries subject to these sanctions, including Iran, Sudan, Syria, Russia and Cuba. These dealings represent an insignificant amount of our consolidated revenues and income but expose us to an increased risk of violating applicable sanctions regulations, which are complex and subject to frequent change. Additional restrictions may be enacted, enforced or interpreted in a way that may adversely affect our operations.

We have compliance programs in place, including policies, training and various forms of monitoring, designed to address the risks discussed above. Nonetheless, these programs and policies may not always protect us from conduct by individual employees that violate these laws. Violations or allegations of violations of these laws may result in large civil and criminal penalties, debarment from participating in government programs, diversion of management time, attention and resources and may otherwise have an adverse effect on our business, financial condition and results of operations. For more information related to the company’s ongoing government investigations, please refer to Note 16 in Item 8 of this Annual Report on Form 10-K.

The laws and regulations discussed above are broad in scope and subject to evolving interpretations, which could require us to incur substantial cost associated with compliance or to alter one or more of our sales and marketing practices and may subject us to enforcement actions which could adversely affect our business, financial condition and results of operations.

If reimbursement or other payment for our current or future products is reduced or modified in the United States or abroad, including through the implementation or repeal of government-sponsored healthcare reform or other similar actions, cost containment measures, or changes to policies with respect to pricing, taxation or rebates, then our business could suffer.

Sales of our products depend, in part, on the extent to which the costs of our products are paid by both public and private payers. These payers include Medicare, Medicaid, and private healthcare insurers in the United States and foreign governments and third-party payers outside the United States. Public and private payers are increasingly challenging the prices charged for medical products

and services. We may continue to experience downward pricing pressures from any or all of these payers which could result in an adverse effect on our business, financial condition and operational results.

Global efforts toward healthcare cost containment continue to exert pressure on product pricing. Governments around the world use various mechanisms to control healthcare expenditures, such as price controls, the formation of public contracting authorities, product formularies (lists of recommended or approved products), and competitive tenders which require the submission of a bid to sell products. Sales of our products are dependent, in part, on the availability of reimbursement by government agencies and healthcare programs, as well as insurance companies and other private payers. In muchthe United States, the federal government and many states have adopted or proposed initiatives relating to Medicaid and other health programs that may limit reimbursement or increase rebates that we and other providers are required to pay to the state. In addition to government regulation, managed care organizations in the United States, which include medical insurance companies, medical plan administrators, health-maintenance organizations, hospital and physician alliances and pharmacy benefit managers, continue to put pressure on the price and usage of healthcare products. Managed care organizations seek to contain healthcare expenditures, and their purchasing strength has been increasing due to their consolidation into fewer, larger organizations and a growing number of enrolled patients. We face similar issues outside of the United States. In Europe and Latin America, Asia and Australia, for example, the government provides healthcare at low cost to patients, and controls its expenditures by purchasing products through public tenders, collective purchasing, regulating prices, setting reference prices in public tenders or limiting reimbursement or patient access to certain products. Additionally, China has been implementing volume-based procurement policies and a series of centralized reforms on both a national and regional basis which have resulted in significant price cuts for pharmaceuticals and medical consumables. For further discussion, refer to Item 1A. Risk Factors of this Annual Report on Form 10-K.
