BUSINESS INTRODUCTION Overview UnitedHealth Group is a diversified health and well-being company dedicated to helping people live healthier lives and helping to make the health system work better for everyone. The terms “we,” “our,” “us,” “its,” “UnitedHealth Group,” or the “Company” used in this report refer to UnitedHealth Group Incorporated and its subsidiaries. Through our diversified family of businesses, we leverage core competencies in advanced, enabling technology; health care data, information and intelligence; and clinical care management and coordination to help meet the demands of the health system. These core competencies are deployed within our two distinct, but strategically aligned, business platforms: health benefits operating under UnitedHealthcare and health services operating under Optum. UnitedHealthcare provides health care benefits to an array of customers and markets. UnitedHealthcare Employer & Individual serves employers ranging from sole proprietorships to large, multi-site and national employers, public sector employers and other individuals. UnitedHealthcare Medicare & Retirement delivers health and well-being benefits for Medicare beneficiaries and retirees. UnitedHealthcare Community & State manages health care benefit programs on behalf of state Medicaid and community programs and their participants. UnitedHealthcare Global includes UnitedHealthcare Brazil, a health care company providing health and dental benefits and hospital and clinical services to employer groups and individuals in Brazil, and other diversified global health businesses. Optum is a health services business serving the broad health care marketplace, including payers, care providers, employers, governments, life sciences companies and consumers, through its OptumHealth, OptumInsight and OptumRx businesses. These businesses have dedicated units that help improve overall health system performance through optimizing care quality, reducing costs and improving consumer experience and care provider performance leveraging distinctive capabilities in data and analytics, pharmacy care services, population health, health care delivery and health care operations. Through UnitedHealthcare and Optum, in 2016, we processed more than one half trillion dollars in gross billed charges and we managed more than $200 billion in aggregate health care spending on behalf of the customers and consumers we serve. Our revenues are derived from premiums on risk-based products; fees from management, administrative, technology and consulting services; sales of a wide variety of products and services related to the broad health and well-being industry; and investment and other income. Our two business platforms have four reportable segments: • • • • UnitedHealthcare, which includes UnitedHealthcare Employer & Individual, UnitedHealthcare Medicare & Retirement, UnitedHealthcare Community & State and UnitedHealthcare Global; OptumHealth; OptumInsight; and OptumRx. For our financial results and the presentation of certain other financial information by segment, including revenues and long-lived fixed assets by geographic source, see Note 13 of Notes to the Consolidated Financial Statements included in Part II, Item 8, “Financial Statements.” 1 UnitedHealthcare Through its health benefits offerings, UnitedHealthcare is enabling better health, helping to control rising health care costs and creating a better health care experience for its customers. UnitedHealthcare’s market position is built on: • • • • • • • strong local market relationships; the breadth of product offerings, which are responsive to many distinct market segments in health care; service and advanced technology; competitive medical and operating cost positions; effective clinical engagement; extensive expertise in distinct market segments; and innovation for customers and consumers. UnitedHealthcare utilizes Optum’s capabilities to help coordinate patient care, improve affordability of medical care, analyze cost trends, manage pharmacy benefits, work with care providers more effectively and create a simpler consumer experience. In the United States, UnitedHealthcare arranges for discounted access to care through networks that include 1 million physicians and other health care professionals and approximately 6,000 hospitals and other facilities. UnitedHealthcare is subject to extensive government regulation. See further discussion of our regulatory environment below under “Government Regulation” and in Part II, Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations.” UnitedHealthcare Employer & Individual UnitedHealthcare Employer & Individual offers an array of consumer-oriented health benefit plans and services nationwide for large national employers, public sector employers, mid-sized employers, small businesses, and individuals. UnitedHealthcare Employer & Individual provides access to medical services for over 30 million people on behalf of our customers and alliance partners. This includes more than 200,000 employer customers across all 50 states. Products are offered through affiliates that are licensed as insurance companies, health maintenance organizations (HMOs), or third-party administrators (TPAs). Large employer groups typically use self-funded arrangements where UnitedHealthcare Employer & Individual earns a service fee. Smaller employer groups and individuals are more likely to purchase risk-based products because they are less willing or unable to bear a greater potential liability for health care expenditures. Through its risk-based product offerings, UnitedHealthcare Employer & Individual assumes the risk of both medical and administrative costs for its customers in return for a monthly premium, which is typically a fixed rate per individual served for a one-year period. When providing administrative and other management services to customers that elect to self-fund the health care costs of their employees and employees’ dependents, UnitedHealthcare Employer & Individual receives a fixed monthly service fee per individual served. These customers retain the risk of financing medical benefits for their employees and employees’ dependents, while UnitedHealthcare Employer & Individual provides services such as coordination and facilitation of medical and related services to customers, consumers and health care professionals, administration of transaction processing and access to a contracted network of physicians, hospitals and other health care professionals, including dental and vision. The consolidated purchasing capacity represented by the individuals served by UnitedHealth Group makes it possible for UnitedHealthcare Employer & Individual to contract for cost-effective access to a large number of conveniently located care professionals and facilities. UnitedHealthcare Employer & Individual has relationships with network care providers that integrate data and analytics, implement value-based payments and care management programs, and enable us to jointly better manage health care across populations. 2 UnitedHealthcare Employer & Individual typically distributes its products through consultants or direct sales in the larger employer and public sector segments. In the smaller group segment of the commercial marketplace, UnitedHealthcare Employer & Individual’s distribution system consists primarily of direct sales and sales through collaboration with brokers and agents. UnitedHealthcare Employer & Individual also distributes products through wholesale agents or agencies that contract with health insurance carriers to distribute individual or group benefits and provide other related services to their customers. UnitedHealthcare Employer & Individual also distributes its products through professional employer organizations, associations and, increasingly, through both multi-carrier and its own proprietary private exchange marketplaces. Direct-to-consumer sales are supported by participation in multi-carrier health insurance marketplaces for individuals and small groups through exchanges. In 2017, UnitedHealthcare Employer & Individual will participate in individual public exchanges in three states, a reduction from 34 states in 2016. UnitedHealthcare Employer & Individual’s diverse product portfolio offers a continuum of benefit designs, price points and approaches to consumer engagement, which provides the flexibility to meet the coverage needs of employers of all sizes. The market for health benefit products is shifting, with benefit and network offerings shaped, at least in part, by the requirements and effects of the Patient Protection and Affordable Care Act (ACA) and related federal and state regulations, increased employer focus on quality and employee engagement and the urgent need to align the system around value. Cost pressures are stimulating demand for improved health care affordability and more coordinated care. UnitedHealthcare Employer & Individual is responding to this demand with medical network and contracting constructs (such as performance incentives and benefit designs that direct more patients to higher-performing care providers), alternative access to affordable and convenient care (such as through telehealth appointments with registered nurses and physicians) and a consumer-responsive service called Advocate4Me. UnitedHealthcare Employer & Individual offers affordable products and actionable information to enable better health outcomes and to help employers attract and retain talent. UnitedHealthcare Employer & Individual’s major product families include: Traditional Products. Traditional products include a full range of medical benefits and network options from managed plans, such as Choice and Options PPO, to more traditional indemnity products. The plans offer a full spectrum of covered services, including preventive care, direct access to specialists and catastrophic protection. Consumer Engagement Products. Consumer engagement products couple plan design with financial accounts to increase individuals’ responsibility for their health and well-being. This suite of products includes high- deductible consumer-driven benefit plans, which include health reimbursement accounts (HRAs), health savings accounts (HSAs) and consumer engagement services such as personalized behavioral incentive programs and consumer education. During 2016, more than 40,000 employer-sponsored benefit plans, including nearly 400 employers in the large group self-funded market, purchased HRA or HSA products from us. Clinical and Pharmacy Products. UnitedHealthcare Employer & Individual offers a comprehensive suite of clinical and pharmacy care services products, which complement its service offerings by improving quality of care, engaging members and providing cost-saving options. All UnitedHealthcare Employer & Individual members are provided access to clinical products that help them make better health care decisions and better use of their medical benefits, which contribute to improved health and lowered medical expenses. Each medical plan has a core set of clinical programs embedded in the offering, with additional services available depending on offering type (risk-based or self-funded), line of business (e.g., small business, key accounts, public sector, national accounts or individuals) and clinical need. UnitedHealthcare Employer & Individual’s clinical programs include: • • wellness programs; decision support; 3 • • • • • • • utilization management; case and disease management; complex condition management; on-site programs, including biometrics and flu shots; incentives to reinforce positive behavior change; mental health/substance use disorder management; and employee assistance programs. UnitedHealthcare Employer & Individual’s comprehensive and integrated pharmaceutical care services promote lower costs by using formulary programs to produce better unit costs, encouraging consumers to use drugs that offer improved value and outcomes, helping consumers take actions to improve their health and supporting the appropriate use of drugs based on clinical evidence through physician and consumer education programs. Specialty Offerings. UnitedHealthcare Employer & Individual also delivers dental, vision, life, critical illness and disability product offerings through an integrated approach, including a network of more than 20,000 vision offices and more than 80,000 dental offices, in private and retail settings. UnitedHealthcare Military & Veterans. UnitedHealthcare Military & Veterans is the provider of health care services for nearly 3 million active duty and retired military service members and their families in 21 states under the Department of Defense’s (DoD) TRICARE Managed Care Support contract. The contract that began on April 1, 2013 is scheduled to conclude in 2017 and has not been renewed. UnitedHealthcare Medicare & Retirement UnitedHealthcare Medicare & Retirement provides health and well-being services to individuals age 50 and older, addressing their unique needs for preventive and acute health care services, as well as services dealing with chronic disease and other specialized issues common among older individuals. UnitedHealthcare Medicare & Retirement is fully dedicated to serving this growing senior market segment, providing products and services in all 50 states, the District of Columbia and most U.S. territories. UnitedHealthcare Medicare & Retirement has distinct pricing, underwriting, clinical program management and marketing capabilities dedicated to health products and services in this market. UnitedHealthcare Medicare & Retirement offers a selection of products that allow people to obtain the health coverage and services they need as their circumstances change. UnitedHealthcare Medicare & Retirement is positioned to serve seniors who find that affordable, network-based care provided through Medicare Advantage plans meets their unique health care needs. For those who prefer traditional fee-for-service Medicare, UnitedHealthcare Medicare & Retirement offers both Medicare Supplement and Medicare Prescription Drug Benefit (Medicare Part D) prescription drug programs that supplement their government-sponsored Medicare by providing additional benefits and coverage options. Beneficiaries with special needs are served through UnitedHealthcare Medicare & Retirement Dual, Chronic and Institutional Special Needs Plans (SNPs) in many markets. UnitedHealthcare Medicare & Retirement services include care management and clinical management programs, a nurse health line service, 24-hour access to health care information, access to discounted health services from a network of care providers and administrative services. UnitedHealthcare Medicare & Retirement has extensive distribution capabilities and experience, including direct marketing to consumers on behalf of its key clients: AARP, the nation’s largest membership organization dedicated to the needs of people age 50 and over, and state and U.S. government agencies. Products are also offered through employer groups and agent channels. 4 UnitedHealthcare Medicare & Retirement’s major product categories include: Medicare Advantage. UnitedHealthcare Medicare & Retirement provides health care coverage for seniors and other eligible Medicare beneficiaries primarily through the Medicare Advantage program administered by CMS, including Medicare Advantage HMO plans, preferred provider organization (PPO) plans, Point-of-Service plans, Private-Fee-for-Service plans and SNPs. Under the Medicare Advantage program, UnitedHealthcare Medicare & Retirement provides health insurance coverage in exchange for a fixed monthly premium per member from CMS plus, in some cases, monthly consumer premiums. Premium amounts received from CMS vary based on the geographic areas in which members reside; demographic factors such as age, gender and institutionalized status; and the health status of the individual. Medicare Advantage plans are designed to compete at the local level, taking into account member and care provider preferences, competitor offerings, our quality and cost initiatives, our historical financial results and the long-term payment rate outlook for each geographic area. UnitedHealthcare Medicare & Retirement served 3.6 million people through its Medicare Advantage products as of December 31, 2016. Built on more than 20 years of experience, UnitedHealthcare Medicare & Retirement’s senior-focused care management model operates at a medical cost level below that of traditional Medicare, while helping seniors live healthier lives. Through UnitedHealth Group’s HouseCalls program, nurse practitioners performed more than 1 million in-home preventative care visits in 2016 to address unmet care opportunities and close gaps in care. For high-risk patients in certain care settings and programs, UnitedHealthcare Medicare & Retirement uses proprietary, automated medical record software that enables clinical care teams to capture and track patient data and clinical encounters, creating a comprehensive set of care information that bridges across home, hospital and nursing home care settings. Proprietary predictive modeling tools help identify members at high risk and allow care managers to reach out to those members and create individualized care plans that help them obtain the right care, in the right place, at the right time. Medicare Part D. UnitedHealthcare Medicare & Retirement provides Medicare Part D benefits to beneficiaries throughout the United States and its territories through its Medicare Advantage and stand-alone Medicare Part D plans. The stand-alone Medicare Part D plans address a large spectrum of beneficiaries’ needs and preferences for their prescription drug coverage, including low cost prescription options. Each of the plans includes the majority of the drugs covered by Medicare and provides varying levels of coverage to meet the diverse needs of Medicare beneficiaries. As of December 31, 2016, UnitedHealthcare enrolled 8.6 million people in the Medicare Part D programs, including 4.9 million individuals in the stand-alone Medicare Part D plans with the remainder in Medicare Advantage plans incorporating Medicare Part D coverage. Medicare Supplement. UnitedHealthcare Medicare & Retirement is currently serving 4.7 million seniors nationwide through various Medicare Supplement products in association with AARP. UnitedHealthcare Medicare & Retirement offers a full range of supplemental products at diverse price points. These products cover the various levels of coinsurance and deductible gaps that seniors are exposed to in the traditional Medicare program. Premium revenues from the Centers for Medicare & Medicaid Services (CMS) represented 25% of UnitedHealth Group’s total consolidated revenues for the year ended December 31, 2016, most of which were generated by UnitedHealthcare Medicare & Retirement. UnitedHealthcare Community & State UnitedHealthcare Community & State is dedicated to serving state programs that care for the economically disadvantaged, the medically underserved and those without the benefit of employer-funded health care coverage, in exchange for a monthly premium per member from the state program. In some cases, these premiums are subject to experience or risk adjustments. UnitedHealthcare Community & State’s primary customers oversee Medicaid plans, Children’s Health Insurance Programs (CHIP), SNPs, integrated Medicare- Medicaid plans (MMP) and other federal, state and community health care programs. As of December 31, 2016, 5 UnitedHealthcare Community & State participated in programs in 24 states and the District of Columbia, and served 5.9 million beneficiaries. The Affordable Care Act provided for optional Medicaid expansion effective January 1, 2014. As of December 31, 2016, UnitedHealthcare Community & State served more than 1 million people through Medicaid expansion programs in 15 states. States using managed care services for Medicaid beneficiaries select health plans by using a formal bid process or by awarding individual contracts. A number of factors are considered by UnitedHealthcare Community & State when choosing programs for participation, including the state’s commitment and consistency of support for its Medicaid managed care program in terms of service, innovation and funding; the eligible population base, both immediate and long term; and the structure of the projected program. UnitedHealthcare Community & State works with its state customers to advocate for actuarially sound rates that are commensurate with medical cost trends. The primary categories of eligibility for the programs served by UnitedHealthcare Community & State and its participation are: • • • • Temporary Assistance to Needy Families, primarily women and children – 22 markets; CHIP – 21 markets; Aged, Blind and Disabled – 20 markets; SNP – 15 markets; • Medicaid Expansion – 15 markets; • • • Long-Term Services and Supports – 12 markets; childless adult programs for the uninsured – 2 markets; other programs (e.g., developmentally disabled, rehabilitative services) – 5 markets; and • MMP – 2 markets. These health plans and care programs offered are designed to address the complex needs of the populations they serve, including the chronically ill, those with disabilities and people with a higher risk of medical, behavioral and social conditions. UnitedHealthcare Community & State administers benefits for the unique needs of children, pregnant women, adults, seniors and those who are institutionalized or are nursing home eligible. These individuals often live in areas that are medically underserved and are less likely to have a consistent relationship with the medical community or a care provider. These individuals also tend to face significant social and economic challenges. UnitedHealthcare Community & State leverages the national capabilities of UnitedHealth Group locally, supporting effective care management, strong regulatory partnerships, greater administrative efficiency, improved clinical outcomes and the ability to adapt to a changing national and local market environment. UnitedHealthcare Community & State coordinates resources among family, physicians, other health care providers, and government and community-based agencies and organizations to facilitate continuous and effective care. Approximately 75% of the people in state Medicaid programs are served by managed care, but this population represents only 40% of total Medicaid spending. UnitedHealthcare Community & State’s business development opportunities include entering fee-for-service markets converting to managed care, which represents a population of nearly 8 million people; and growing in existing managed care markets, including state-carve-ins of populations with more complex needs requiring more sophisticated models of care. This expansion includes integrated management of physical, behavioral, long-term care services and supports and social services by applying strong data analytics and community-based collaboration. UnitedHealthcare Community & State continues to evolve its clinical model to enhance quality and the clinical experience for the people it serves. The model allows UnitedHealthcare Community & State to quickly identify the people who could benefit most from more highly coordinated care; typically, the 5% of members who are most at risk and drive over 50% of states’ medical costs. 6 UnitedHealthcare Global UnitedHealthcare Global participates in international markets through national “in country” and cross-border strategic approaches. UnitedHealthcare Global’s cross-border health care business provides comprehensive health benefits, care management and care delivery for multinational employers, governments and individuals around the world. UnitedHealthcare Global’s goal is to create health care business solutions that are based on local expertise, infrastructure, culture and needs.

OptumHealth builds high-performing networks and centers of excellence across the care continuum, by working directly with physicians to advance population health management and by coordinating care for the most medically complex patients.

For its financial services offerings, OptumHealth charges fees and earns investment income on managed funds. OptumHealth sells its products primarily through its direct sales force, strategic collaborations and external producers in three markets: employers (which includes the sub-markets of large, mid-sized and small employers), payers (which includes the sub-markets of health plans, TPAs, underwriter/stop-loss carriers and individual market intermediaries) and government entities (which includes states, CMS, DoD, the Veterans Administration and other federal procurement agencies). OptumHealth serves patients and care providers through its local ambulatory care services business and delivers care through a physician-led, patient-centric and data-driven organization comprised of over 20,000 employed, managed and contracted physicians. OptumHealth also enables care providers’ transition from traditional, fee-for-service care delivery to performance-based delivery and payment models that put patient health and outcomes first, such as those emerging through accountable care organizations (ACOs) and local care provider partnerships. Through OptumHealth’s strategic partnerships, alliances and ownership arrangements it helps care providers adopt new approaches and technologies that improve the coordination of care across all providers involved in patient care. MedExpress’ nearly 200 neighborhood care centers provide urgent and walk-in care services with a consumer- friendly approach.

During 2016, Optum Bank processed over $100 billion in medical payments to physicians and other health care providers. Organizations across the health system rely on Optum to manage and improve payment flows through its highly automated, scalable, electronic payment systems. OptumInsight OptumInsight provides services, technology and health care expertise to major participants in the health care industry. OptumInsight’s capabilities are focused on data and analytics, technology and information that help improve the quality of care and drive greater efficiency in the health care system. Hospital systems, physicians, health plans, governments, life sciences companies and other organizations that comprise the health care industry depend on OptumInsight to help them improve performance, achieve efficiency, reduce costs, meet compliance mandates and modernize their core operating systems to meet the changing needs of the health system. Many of OptumInsight’s software and information products and professional services are delivered over extended periods, often several years. OptumInsight maintains an order backlog to track unearned revenues under these long-term arrangements. The backlog consists of estimated revenue from signed contracts, other legally binding agreements and anticipated contract renewals based on historical experience with OptumInsight’s customers. OptumInsight’s aggregate backlog at December 31, 2016, was $12.6 billion, of which $6.9 billion is expected to be realized within the next 12 months. This includes $4.5 billion related to intersegment agreements, all of which are in the current portion of the backlog. OptumInsight’s aggregate backlog at December 31, 2015, was $10.4 billion. OptumInsight cannot provide any assurance that it will be able to realize all of the revenues included in the backlog due to uncertainties with regard to the timing and scope of services and the potential for cancellation, non-renewal or early termination of service arrangements. OptumInsight’s products and services are sold primarily through a direct sales force. OptumInsight’s products are also supported and distributed through an array of alliances and business partnerships with other technology vendors, who integrate and interface OptumInsight’s products with their applications. OptumInsight believes it is well positioned to address the needs of four primary market segments: care providers (e.g., physicians and hospital systems), health plans, governments and life sciences companies. Care Providers. Serving more than four out of five U.S. hospitals and tens of thousands of physicians, OptumInsight assists care providers in meeting their challenge to improve patient outcomes and care amid changing payment models and pressures. OptumInsight brings a broad array of solutions to help care providers meet these challenges, with particular focus on clinical performance and quality improvement, population health management, data management and analytics, revenue management, cost containment, compliance, cloud- enabled collaboration and consumer engagement. Health Plans. OptumInsight serves approximately 300 health plans through cost-effective, technology-enabled solutions that help them improve efficiency, understand and optimize growth while managing risk, deliver on clinical performance and compliance goals, and build and manage strong networks of care. Governments. OptumInsight provides services tailored to government payers, including data and analytics technology, claims management and payment accuracy services, and strategic consulting. Life Sciences. OptumInsight provides services to global life sciences companies. These companies look to OptumInsight for data, analytics and expertise in core areas of health economics and outcomes research, market access consulting, integrated clinical and health care claims data and informatics services, epidemiology and drug safety, and patient reported outcomes. 9 OptumRx OptumRx provides a full spectrum of pharmacy care services to more than 65 million people in the United States through its network of more than 67,000 retail pharmacies and multiple home delivery facilities throughout the country.

OptumRx’s distribution system consists primarily of health insurance brokers and other health care consultants and direct sales. GOVERNMENT REGULATION Most of our health and well-being businesses are subject to comprehensive federal, state and international laws and regulations. We are regulated by federal, state and international regulatory agencies that generally have discretion to issue regulations and interpret and enforce laws and rules. The regulations can vary significantly from jurisdiction to jurisdiction and the interpretation of existing laws and rules also may change periodically. Domestic and international governments continue to enact and consider various legislative and regulatory proposals that could materially impact certain aspects of the health care system. New laws, regulations and rules, or changes in the interpretation of existing laws, regulations and rules, including as a result of changes in the political climate, could adversely affect our business. If we fail to comply with, or fail to respond quickly and appropriately to changes in, applicable laws, regulations and rules, our business, results of operations, financial position and cash flows could be materially and adversely affected. See Part I, Item 1A, “Risk Factors” for a discussion of the risks related to our compliance with federal, state and international laws and regulations. Federal Laws and Regulation We are subject to various levels of U.S. federal regulation. For example, when we contract with the federal government, we are subject to federal laws and regulations relating to the award, administration and performance of U.S. government contracts. CMS regulates our UnitedHealthcare businesses and certain aspects of our Optum businesses. Payments by CMS to our businesses are subject to regulations, including those governing fee-for-service and the submission of information relating to the health status of enrollees for purposes of determining the amounts of certain payments to us. CMS also has the right to audit our performance to determine our compliance with CMS contracts and regulations and the quality of care we provide to Medicare beneficiaries. Our commercial business is further subject to CMS audits related to medical loss ratios (MLRs), risk adjustment and reinsurance data. UnitedHealthcare Community & State has Medicaid and CHIP contracts that are subject to federal regulations regarding services to be provided to Medicaid enrollees, payment for those services and other aspects of these programs. There are many regulations affecting Medicare and Medicaid compliance and the regulatory environment with respect to these programs is complex. We are also subject to federal law and regulations 10 relating to the administration of contracts with federal agencies. Our business is also subject to laws and regulations relating to consumer protection, anti-fraud and abuse, anti-kickbacks, false claims, prohibited referrals, inappropriately reducing or limiting health care services, anti-money laundering, securities and antitrust. Affordable Care Act. The ACA expanded access to coverage and modified aspects of the commercial insurance market, as well as the Medicaid and Medicare programs, CHIP and other aspects of the health care system. Among other requirements, the ACA expanded dependent coverage to age 26, expanded benefit requirements, eliminated certain annual and lifetime maximum limits, eliminated certain pre-existing condition limits, required coverage for preventative services without cost to members, required premium rebates if certain MLRs are not satisfied, granted members new and additional appeal rights, created new premium rate review processes, established a system of state and federal exchanges through which consumers can purchase health coverage, imposed new requirements on the format and content of communications (such as explanations of benefits) between health insurers and their members, introduced new risk sharing programs, reduced the Medicare Part D coverage gap and reduced payments to private plans offering Medicare Advantage. The ACA is affecting how we do business and could impact our results of operations, financial position and cash flows. See also Part I, Item 1A, “Risk Factors” for a discussion of the risks related to the ACA and related matters. Privacy, Security and Data Standards Regulation. The administrative simplification provisions of the Health Insurance Portability and Accountability Act of 1996, as amended (HIPAA), apply to both the group and individual health insurance markets, including self-funded employee benefit plans. Federal regulations related to HIPAA contain minimum standards for electronic transactions and code sets and for the privacy and security of protected health information. The Health Information Technology for Economic and Clinical Health Act (HITECH) imposed requirements on uses and disclosures of health information; included contracting requirements for HIPAA business associate agreements; extended parts of HIPAA privacy and security provisions to business associates; added federal data breach notification requirements for covered entities and business associates and reporting requirements to the U.S. Department of Health and Human Services (HHS) and the Federal Trade Commission and, in some cases, to the local media; strengthened enforcement and imposed higher financial penalties for HIPAA violations and, in certain cases, imposed criminal penalties for individuals, including employees. In the conduct of our business, depending on the circumstances, we may act as either a covered entity or a business associate. Federal consumer protection laws may also apply in some instances to privacy and security practices related to personally identifiable information. The use and disclosure of individually identifiable health data by our businesses is also regulated in some instances by other federal laws, including the Gramm-Leach-Bliley Act (GLBA) or state statutes implementing GLBA. These federal laws and state statutes generally require insurers to provide customers with notice regarding how their non-public personal health and financial information is used and the opportunity to “opt out” of certain disclosures before the insurer shares such information with a third party, and generally require safeguards for the protection of personal information. Neither the GLBA nor HIPAA privacy regulations preempt more stringent state laws and regulations that may apply to us, as discussed below. ERISA. The Employee Retirement Income Security Act of 1974, as amended (ERISA), regulates how our services are provided to or through certain types of employer-sponsored health benefit plans. ERISA is a set of laws and regulations that is subject to periodic interpretation by the U.S. Department of Labor (DOL) as well as the federal courts. ERISA sets forth standards on how our business units may do business with employers who sponsor employee health benefit plans, particularly those that maintain self-funded plans. Regulations established by the DOL subject us to additional requirements for claims payment and member appeals under health care plans governed by ERISA. 11 State Laws and Regulation Health Care Regulation. Our insurance and HMO subsidiaries must be licensed by the jurisdictions in which they conduct business. All of the states in which our subsidiaries offer insurance and HMO products regulate those products and operations. The states require periodic financial reports and establish minimum capital or restricted cash reserve requirements. The National Association of Insurance Commissioners has adopted model regulations that, where implemented by states, require expanded governance practices and risk and solvency assessment reporting. Most states have adopted these or similar measures to expand the scope of regulations relating to corporate governance and internal control activities of HMOs and insurance companies. We are required to maintain a risk management framework and file a confidential self-assessment report with state insurance regulators. Reports are filed annually with Connecticut, our lead regulator, and with New York, as required by that state’s regulation. Certain states have also adopted their own regulations for minimum MLRs with which health plans must comply. In addition, a number of state legislatures have enacted or are contemplating significant reforms of their health insurance markets, either independent of or to comply with or be eligible for grants or other incentives in connection with the ACA, which may affect our operations and our financial results. Health plans and insurance companies are regulated under state insurance holding company regulations. Such regulations generally require registration with applicable state departments of insurance and the filing of reports that describe capital structure, ownership, financial condition, certain intercompany transactions and general business operations. Most state insurance holding company laws and regulations require prior regulatory approval of acquisitions and material intercompany transfers of assets, as well as transactions between the regulated companies and their parent holding companies or affiliates. These laws may restrict the ability of our regulated subsidiaries to pay dividends to our holding companies. Some of our business activity is subject to other health care-related regulations and requirements, including PPO, Managed Care Organization (MCO), utilization review (UR), TPA, pharmacy care services, durable medical equipment or care provider-related regulations and licensure requirements. These regulations differ from state to state and may contain network, contracting, product and rate, licensing and financial and reporting requirements. There are laws and regulations that set specific standards for delivery of services, appeals, grievances and payment of claims, adequacy of health care professional networks, fraud prevention, protection of consumer health information, pricing and underwriting practices and covered benefits and services. State health care anti- fraud and abuse prohibitions encompass a wide range of activities, including kickbacks for referral of members, billing for unnecessary medical services and improper marketing. Certain of our businesses are subject to state general agent, broker and sales distributions laws and regulations. UnitedHealthcare Community & State and certain of our Optum businesses are subject to regulation by state Medicaid agencies that oversee the provision of benefits to our Medicaid and CHIP beneficiaries and to our dually eligible (for Medicare and Medicaid) beneficiaries. We also contract with state governmental entities and are subject to state laws and regulations relating to the award, administration and performance of state government contracts. Guaranty Fund Assessments. Under state guaranty association laws, certain insurance companies can be assessed (up to prescribed limits) for certain obligations to the policyholders and claimants of impaired or insolvent insurance companies that write the same line or similar lines of business. Some states have similar laws relating to HMOs and other payers such as consumer operated and oriented plans (co-ops) established under the ACA. Assessments are generally based on a formula relating to our premiums in the state compared to the premiums of other insurers and could be spread out over a period of years. Some states permit member insurers to recover assessments paid through full or partial premium tax offsets or through premiums. Any such assessment could expose our insurance entities and other insurers to the risk of paying a portion of an impaired or insolvent insurance company’s claims through state guaranty associations. Pharmacy Regulation. OptumRx’s businesses include home delivery and specialty pharmacies that must be licensed as pharmacies in the states in which they are located. Certain of our home delivery and specialty pharmacies must also register with the U.S. Drug Enforcement Administration (DEA) and individual state controlled substance authorities to dispense controlled substances. In addition to the laws and regulations in the 12 states where our home delivery and specialty pharmacies are located, laws and regulations in non-resident states where we deliver pharmaceuticals may also apply, including the requirement to register with the board of pharmacy in the non-resident state. These non-resident states generally expect our home delivery and specialty pharmacies to follow the laws of the state in which the pharmacies are located, but some states also require us to comply with the laws of that non-resident state when pharmaceuticals are delivered there. As certain of our home delivery and specialty pharmacies maintain eligibility as Medicare and state Medicaid providers, their participation in the programs requires them to comply with the applicable Medicare and Medicaid provider rules and regulations. Other laws and regulations affecting our home delivery and specialty pharmacies include federal and state statutes and regulations governing the labeling, packaging, advertising and adulteration of prescription drugs and dispensing of controlled substances. See Part I, Item 1A, “Risk Factors” for a discussion of the risks related to our pharmacy care services businesses. State Privacy and Security Regulations. A number of states have adopted laws and regulations that may affect our privacy and security practices, such as state laws that govern the use, disclosure and protection of social security numbers and sensitive health information or that are designed to implement GLBA or protect credit card account data. State and local authorities increasingly focus on the importance of protecting individuals from identity theft, with a significant number of states enacting laws requiring businesses to notify individuals of security breaches involving personal information. State consumer protection laws may also apply to privacy and security practices related to personally identifiable information, including information related to consumers and care providers. Additionally, different approaches to state privacy and insurance regulation and varying enforcement philosophies in the different states may materially and adversely affect our ability to standardize our products and services across state lines. See Part I, Item 1A, “Risk Factors” for a discussion of the risks related to compliance with state privacy and security regulations. Corporate Practice of Medicine and Fee-Splitting Laws. Certain of our businesses function as direct medical service providers and, as such, are subject to additional laws and regulations. Some states have corporate practice of medicine laws that prohibit specific types of entities from practicing medicine or employing physicians to practice medicine. Moreover, some states prohibit certain entities from sharing in the fees or revenues of a professional practice (fee-splitting). These prohibitions may be statutory or regulatory, or may be imposed through judicial or regulatory interpretation. The laws, regulations and interpretations in certain states have been subject to limited judicial and regulatory interpretation and are subject to change. Consumer Protection Laws. Certain of our businesses participate in direct-to-consumer activities and are subject to regulations applicable to on-line communications and other general consumer protection laws and regulations. Banking Regulation Optum Bank is subject to regulation by federal banking regulators, including the Federal Deposit Insurance Corporation, which performs annual examinations to ensure that the bank is operating in accordance with federal safety and soundness requirements, and the Consumer Financial Protection Bureau, which may perform periodic examinations to ensure that the bank is in compliance with applicable consumer protection statutes, regulations and agency guidelines. Optum Bank is also subject to supervision and regulation by the Utah State Department of Financial Institutions, which carries out annual examinations to ensure that the bank is operating in accordance with state safety and soundness requirements and performs periodic examinations of the bank’s compliance with applicable state banking statutes, regulations and agency guidelines. In the event of unfavorable examination results from any of these agencies, the bank could become subject to increased operational expenses and capital requirements, enhanced governmental oversight and monetary penalties. International Regulation Certain of our businesses operate internationally and are subject to regulation in the jurisdictions in which they are organized or conduct business. These regulatory regimes vary from jurisdiction to jurisdiction. In addition, our non-U.S. businesses and operations are subject to U.S. laws that regulate the conduct and activities of U.S.- based businesses operating abroad, such as the Foreign Corrupt Practices Act (FCPA), which prohibits offering, 13 promising, providing or authorizing others to give anything of value to a foreign government official to obtain or retain business or otherwise secure a business advantage. COMPETITION As a diversified health and well-being services company, we operate in highly competitive markets. Our competitors include managed health care companies, insurance companies, HMOs, TPAs and business services outsourcing companies, health care professionals that have formed networks to contract directly with employers or with CMS, specialty benefit providers, government entities, population health management companies and various health information and consulting companies. For our UnitedHealthcare businesses, our competitors include Aetna Inc., Anthem, Inc., Centene Corporation, Cigna Corporation, Humana Inc., Kaiser Permanente, numerous for-profit and not-for-profit organizations operating under licenses from the Blue Cross Blue Shield Association and, with respect to our Brazilian operations, several established competitors in Brazil and other enterprises that serve more limited geographic areas. For our OptumRx businesses, our competitors include CVS Health Corporation, Express Scripts, Inc. and Prime Therapeutics LLC. New entrants into the markets in which we compete, as well as consolidation within these markets, also contribute to a competitive environment. We compete on the basis of the sales, marketing and pricing of our products and services; product innovation; consumer engagement and satisfaction; the level and quality of products and services; care delivery; network and clinical management capabilities; market share; product distribution systems; efficiency of administration operations; financial strength; and marketplace reputation. If we fail to compete effectively to maintain or increase our market share, including by maintaining or increasing enrollments in businesses providing health benefits, our results of operations, financial position and cash flows could be materially and adversely affected. See Part I, Item 1A, “Risk Factors,” for additional discussion of our risks related to competition.

RISK FACTORS CAUTIONARY STATEMENTS The statements, estimates, projections or outlook contained in this Annual Report on Form 10-K include forward- looking statements within the meaning of the Private Securities Litigation Reform Act of 1995 (PSLRA). When used in this Annual Report on Form 10-K and in future filings by us with the SEC, in our news releases, presentations to securities analysts or investors, and in oral statements made by or with the approval of one of our executive officers, the words “believe,” “expect,” “intend,” “estimate,” “anticipate,” “forecast,” “outlook,” “plan,” “project,” “should” or similar words or phrases are intended to identify such forward-looking statements. These statements are intended to take advantage of the “safe harbor” provisions of the PSLRA. These forward- looking statements involve risks and uncertainties that may cause our actual results to differ materially from the expectations expressed or implied in the forward-looking statements. Any forward-looking statement speaks only as of the date of this report and, except as required by law; we undertake no obligation to update any forward- looking statement to reflect events or circumstances, including unanticipated events, after the date of this report. The following discussion contains cautionary statements regarding our business that investors and others should consider. We do not undertake to address in future filings or communications regarding our business or results of operations how any of these factors may have caused our results to differ from discussions or information contained in previous filings or communications. In addition, any of the matters discussed below may have affected past, as well as current, forward-looking statements about future results. Any or all forward-looking statements in this Annual Report on Form 10-K and in any other public filings or statements we make may turn out to be wrong. Our forward-looking statements can be affected by inaccurate assumptions we might make or by known or unknown risks and uncertainties. Many factors discussed below will be important in determining our future results. By their nature, forward-looking statements are not guarantees of future performance or results and are subject to risks, uncertainties and assumptions that are difficult to predict or quantify. If we fail to estimate, price for and manage our medical costs in an effective manner, the profitability of our risk-based products and services could decline and could materially and adversely affect our results of operations, financial position and cash flows. Through our risk-based benefit products, we assume the risk of both medical and administrative costs for our customers in return for monthly premiums. Premium revenues from risk-based benefits products comprise nearly 80% of our total consolidated revenues. We generally use approximately 80% to 85% of our premium revenues to pay the costs of health care services delivered to these customers. The profitability of our products depends in large part on our ability to predict, price for, and effectively manage medical costs. In this regard, federal and state regulatory requirements obligate our commercial, Medicare Advantage and certain state-based Medicaid health plans to maintain minimum MLRs, which could make it more difficult for us to obtain price increases for our products. In addition, our OptumHealth business negotiates capitation arrangements with commercial third- party payers. Under the typical capitation arrangement, the health care provider receives a fixed percentage of a third-party payer’s premiums to cover all or a defined portion of the medical costs provided to the capitated member. If we fail to predict accurately, price for or manage the costs of providing care to our capitated members, our results of operations could be materially and adversely affected. We manage medical costs through underwriting criteria, product design, negotiation of favorable provider contracts and care management programs. Total medical costs are affected by the number of individual services rendered, the cost of each service and the type of service rendered. Our premium revenue on commercial policies is typically at a fixed monthly rate per individual served for a 12-month period and is generally priced one to six 16 months before the contract commences. Our revenue on Medicare policies is based on bids submitted in June the year before the contract year. Although we base the premiums we charge and our Medicare bids on our estimates of future medical costs over the fixed contract period, many factors may cause actual costs to exceed those estimated and reflected in premiums or bids. These factors may include medical cost inflation, increased use of services, increased cost of individual services, natural catastrophes or other large-scale medical emergencies, epidemics, the introduction of new or costly drugs, treatments and technology, new mandated benefits (such as the expansion of essential benefits coverage) or other regulatory changes and insured population characteristics. Relatively small differences between predicted and actual medical costs or utilization rates as a percentage of revenues can result in significant changes in our financial results. For example, if our 2016 medical costs for commercial insured products were 1% higher, without proportionally higher revenues from such products, our annual net earnings for 2016 would have been reduced by approximately $240 million, excluding any offsetting impact from risk adjustment, reinsurance or from reduced premium rebates due to minimum MLRs. In addition, the financial results we report for any particular period include estimates of costs that have been incurred for which claims are still outstanding. These estimates involve an extensive degree of judgment. If these estimates prove inaccurate, our results of operations could be materially and adversely affected. Our business activities are highly regulated and new laws or regulations or changes in existing laws or regulations or their enforcement or application could materially and adversely affect our business. We are regulated by federal, state and local governments in the United States and other countries where we do business. Our insurance and HMO subsidiaries must be licensed by and are subject to regulation in the jurisdictions in which they conduct business. For example, states require periodic financial reports and enforce minimum capital or restricted cash reserve requirements. Health plans and insurance companies are also regulated under state insurance holding company regulations and some of our activities may be subject to other health care-related regulations and requirements, including those relating to PPOs, MCOs, UR and TPA-related regulations and licensure requirements. Some of our UnitedHealthcare and Optum businesses hold or provide services related to government contracts and are subject to U.S. federal and state and non-U.S. self-referral, anti-kickback, medical necessity, risk adjustment, false claims and other laws and regulations governing government contractors and the use of government funds. In addition, under state guaranty association laws, certain insurance companies can be assessed (up to prescribed limits) for certain obligations to the policyholders and claimants of impaired or insolvent insurance companies that write the same line or similar lines of business. Some states have similar laws relating to HMOs and other payers such as consumer operated and oriented plans (co-ops) established under the ACA. Any such assessment could expose our insurance entities and other insurers to the risk of paying a portion of an impaired or insolvent insurance company’s claims through state guaranty associations. Certain of our businesses provide products or services to various government agencies. Our relationships with these government agencies are subject to the terms of contracts that we hold with the agencies and to laws and regulations regarding government contracts. Among others, certain laws and regulations restrict or prohibit companies from performing work for government agencies that might be viewed as an actual or potential conflict of interest. These laws may limit our ability to pursue and perform certain types of work, thereby materially and adversely affecting our results of operations, financial position and cash flows. Certain of our Optum businesses are also subject to regulations, which are distinct from those faced by our insurance and HMO subsidiaries, including, for example, state telemedicine regulations, debt collection laws, banking regulations, distributor and producer licensing requirements, state corporate practice of medicine doctrines, fee-splitting rules, health care facility licensure and certificate of need requirements, some of which could impact our relationships with physicians, hospitals and customers. These risks and uncertainties may materially and adversely affect our ability to market our products and services, or to do so at targeted margins, or may increase the regulatory burdens under which we operate. The laws and rules governing our business and interpretations of those laws and rules are subject to frequent change, and the integration into our businesses of entities that we acquire may affect the way in which existing 17 laws and rules apply to us, including subjecting us to laws and rules that did not previously apply to us. The broad latitude given to the agencies administering, interpreting and enforcing current and future regulations governing our business could force us to change how we do business, restrict revenue and enrollment growth, increase our health care and administrative costs and capital requirements, or expose us to increased liability in courts for coverage determinations, contract interpretation and other actions. We must also obtain and maintain regulatory approvals to market many of our products and services, increase prices for certain regulated products and services and complete certain acquisitions and dispositions or integrate certain acquisitions. For example, premium rates for our health insurance and managed care products are subject to regulatory review or approval in many states and by the federal government. Additionally, we must submit data on all proposed rate increases to HHS for monitoring purposes on many of our products. Geographic and product expansions may be subject to state and federal regulatory approvals. Delays in obtaining necessary approvals or our failure to obtain or maintain adequate approvals could materially and adversely affect our results of operations, financial position and cash flows. Certain of our businesses operate internationally and are subject to regulation in the jurisdictions in which they are organized or conduct business. These regulatory regimes encompass, among other matters, local and cross- border taxation, licensing, tariffs, intellectual property, investment, capital (including minimum solvency margin and reserve requirements), management control, labor, anti-fraud, anti-corruption and privacy and data protection regulations (including requirements for cross-border data transfers) that vary by jurisdiction. We currently operate outside of the United States and in the future may acquire or commence additional businesses based outside of the United States, increasing our exposure to non-U.S. regulatory regimes. For example, our UnitedHealthcare Brazil business subjects us to Brazilian laws and regulations affecting hospitals, managed care and insurance industries and to regulation by Brazilian regulators, including the national regulatory agency for private health insurance and plans, the Agência Nacional de Saúde Suplementar, whose approach to the interpretation, implementation and enforcement of industry regulations could differ from the approach taken by U.S. regulators. In addition, our non-U.S. businesses and operations are subject to U.S. laws that regulate the conduct and activities of U.S.-based businesses operating abroad, such as the FCPA, which prohibits offering, promising, providing or authorizing others to give anything of value to a foreign government official to obtain or retain business or otherwise secure a business advantage. Our failure to comply with U.S. or non-U.S. laws and regulations governing our conduct outside the United States or to establish constructive relations with non-U.S. regulators could adversely affect our ability to market our products and services, or to do so at targeted operating margins, which may have a material adverse effect on our business, financial condition and results of operations. The health care industry is also regularly subject to negative publicity, including as a result of governmental investigations, adverse media coverage and political debate surrounding industry regulation. Negative publicity may adversely affect our stock price and damage our reputation in various markets. The ACA could materially and adversely affect the manner in which we conduct business and our results of operations, financial position and cash flows. Due to its complexity and continued uncertainty, the ACA’s impact remains difficult to predict and could adversely affect us. The ACA includes specific reforms for the individual and small group marketplace, including guaranteed availability of coverage, adjusted community rating requirements (which include elimination of health status and gender rating factors), essential health benefit requirements (resulting in benefit changes for many members) and actuarial value requirements resulting in expanded benefits or reduced member cost sharing (or a combination of both) for many policyholders. In addition, if we do not maintain certain MLRs, we are required to rebate ratable portions of our premiums to our customers. These requirements can cause significant disruptions in local health care markets and adjustments to our business, all of which could materially and adversely affect our results of operations, financial position and cash flows. 18 Our results of operations, financial position and cash flows could be materially and adversely affected if the number of individuals who gain coverage under the ACA varies from our expectations, if the demand for the ACA related products and capabilities offered by our Optum businesses is less than anticipated or if our costs are greater than anticipated. The Trump Administration and Congressional Leaders have expressed their intentions to repeal and replace the ACA. We cannot predict if the ACA will be modified, repealed or replaced, but changes to this law could materially impact our operating results, require us to revise the ways in which we conduct business or put us at risk for loss of business. As a result of our participation in various government health care programs, both as a payer and as a service provider to payers, we are exposed to additional risks associated with program funding, enrollments, payment adjustments, audits and government investigations that could materially and adversely affect our business, results of operations, financial position and cash flows. We participate in various federal, state and local government health care benefit programs, including as a payer in Medicare Advantage, Medicare Part D, various Medicaid programs, CHIP and our TRICARE contract with the DoD, and receive substantial revenues from these programs. Certain of our Optum businesses also provide services to payers participating in government health care programs. A reduction or less than expected increase, or a protracted delay, in government funding for these programs or change in allocation methodologies, or, as is a typical feature of many government contracts, termination of the contract at the option of the government, may materially and adversely affect our results of operations, financial position and cash flows. The government health care programs in which we participate generally are subject to frequent changes, including changes that may reduce the number of persons enrolled or eligible for coverage, reduce the amount of reimbursement or payment levels, reduce our participation in certain service areas or markets, or increase our administrative or medical costs under such programs. Revenues for these programs depend on periodic funding from the federal government or applicable state governments and allocation of the funding through various payment mechanisms. Funding for these government programs depends on many factors outside of our control, including general economic conditions and budgetary constraints at the federal or applicable state level. For example CMS has in the past reduced or frozen Medicare Advantage benchmarks, and additional cuts to Medicare Advantage benchmarks are possible. In addition, from time to time, CMS makes changes to the way it calculates Medicare Advantage risk adjustment payments. Although we have adjusted members’ benefits and premiums on a selective basis, ceased to offer benefit plans in certain counties, and intensified both our medical and operating cost management in response to the benchmark reductions and other funding pressures, these or other strategies may not fully address the funding pressures in the Medicare Advantage program. In addition, payers in the Medicare Advantage program may be subject to reductions in payments from CMS as a result of decreased funding or recoupment pursuant to government audit. Under the Medicaid managed care program, state Medicaid agencies seek bids from eligible health plans to continue their participation in the acute care Medicaid health programs. If we are not successful in obtaining renewals of state Medicaid managed care contracts, we risk losing the members that were enrolled in those Medicaid plans. Under the Medicare Part D program, to qualify for automatic enrollment of low income members, our bids must result in an enrollee premium below a regional benchmark, which is calculated by the government after all regional bids are submitted. If the enrollee premium is not below the government benchmark, we risk losing the members who were auto-assigned to us and will not have additional members auto-assigned to us. In general, our bids are based upon certain assumptions regarding enrollment, utilization, medical costs and other factors. In the event any of these assumptions is materially incorrect, either as a result of unforeseen changes to the programs on which we bid, or submission by our competitors at lower rates than our bids, our results of operations, financial position and cash flows could be materially and adversely affected. Many of the government health care coverage programs in which we participate are subject to the prior satisfaction of certain conditions or performance standards or benchmarks. For example, as part of the ACA, 19 CMS has a system that provides various quality bonus payments to Medicare Advantage plans that meet certain quality star ratings at the local plan level. The star rating system considers various measures adopted by CMS, including, among other things, quality of care, preventative services, chronic illness management and customer satisfaction. Plans must have a rating of four stars or higher to qualify for bonus payments. If we do not maintain or continue to improve our star ratings, our plans may not be eligible for quality bonuses and we may experience a negative impact on our revenues and the benefits that our plans can offer, which could materially and adversely affect our membership levels, results of operations, financial position and cash flows. In addition, under the ACA, Congress authorized CMS and the states to implement MMP managed care demonstration programs to serve dually eligible beneficiaries to improve the coordination of their care. Health plan participation in these demonstration programs is subject to CMS approval of specified care delivery models and the satisfaction of conditions to participation, including meeting certain performance requirements. Any changes in standards or care delivery models that apply to government health care programs, including Medicare, Medicaid and the MMP demonstration programs for dually eligible beneficiaries, or our inability to improve our quality scores and star ratings to meet government performance requirements or to match the performance of our competitors could result in limitations to our participation in or exclusion from these or other government programs, which in turn could materially and adversely affect our results of operations, financial position and cash flows. CMS uses various payment mechanisms to allocate funding for Medicare programs, including adjusting monthly capitation payments to Medicare Advantage plans and Medicare Part D plans according to the predicted health status of each beneficiary as supported by data from health care providers for Medicare Advantage plans, as well as, for Medicare Part D plans, risk-sharing provisions based on a comparison of costs predicted in our annual bids to actual prescription drug costs. Some state Medicaid programs utilize a similar process. For example, our UnitedHealthcare Medicare & Retirement and UnitedHealthcare Community & State businesses submit information relating to the health status of enrollees to CMS or state agencies for purposes of determining the amount of certain payments to us. CMS and the Office of Inspector General for HHS periodically perform risk adjustment data validation (RADV) audits of selected Medicare health plans to validate the coding practices of and supporting documentation maintained by health care providers, and certain of our local plans have been selected for audit. Such audits have in the past resulted and could in the future result in retrospective adjustments to payments made to our health plans, fines, corrective action plans or other adverse action by CMS. We have been and may in the future become involved in routine, regular and special governmental investigations, audits, reviews and assessments. Certain of our businesses have been reviewed or are currently under review, including for compliance with coding and other requirements under the Medicare risk-adjustment model, our chart review programs and related processes. Such investigations, audits or reviews sometimes arise out of or prompt claims by private litigants or whistleblowers that, among other allegations, we failed to disclose certain business practices or, as a government contractor, submitted false claims to the government. Governmental investigations, audits, reviews and assessments could lead to government actions, which could result in adverse publicity, the assessment of damages, civil or criminal fines or penalties, or other sanctions, including restrictions or changes in the way we conduct business, loss of licensure or exclusion from participation in government programs, any of which could have a material adverse effect on our business, results of operations, financial position and cash flows. If we fail to comply with applicable privacy, security and data laws, regulations and standards, including with respect to third-party service providers that utilize sensitive personal information on our behalf, our business, reputation, results of operations, financial position and cash flows could be materially and adversely affected. The collection, maintenance, protection, use, transmission, disclosure and disposal of sensitive personal information are regulated at the federal, state, international and industry levels and requirements are imposed on us by contracts with customers. These laws, rules and requirements are subject to change. Compliance with new privacy and security laws, regulations and requirements may result in increased operating costs, and may constrain or require us to alter our business model or operations. For example, the HITECH amendments to 20 HIPAA imposed further restrictions on our ability to collect, disclose and use sensitive personal information and imposed additional compliance requirements on our business. In addition, the General Data Protection Regulation of the European Union imposes higher potential penalties and more stringent compliance and data security requirements on our ability to collect, process and transfer personal data relating to our European businesses. Many of our businesses are also subject to the Payment Card Industry Data Security Standard, which is a multifaceted security standard that is designed to protect credit card account data as mandated by payment card industry entities. HIPAA requires business associates as well as covered entities to comply with certain privacy and security requirements. While we provide for appropriate protections through our contracts with our third-party service providers and in certain cases assess their security controls, we have limited oversight or control over their actions and practices. Several of our businesses act as business associates to their covered entity customers and, as a result, collect, use, disclose and maintain sensitive personal information in order to provide services to these customers. HHS has announced that it will continue its audit program to assess HIPAA compliance efforts by covered entities and expand it to include business associates. An audit resulting in findings or allegations of noncompliance could have a material adverse effect on our results of operations, financial position and cash flows. Through our Optum businesses, including our Optum Labs business, we maintain a database of administrative and clinical data that is statistically de-identified in accordance with HIPAA standards. Noncompliance or findings of noncompliance with applicable laws, regulations or requirements, or the occurrence of any privacy or security breach involving the misappropriation, loss or other unauthorized disclosure of sensitive personal information, whether by us or by one of our third-party service providers, could have a material adverse effect on our reputation and business, including mandatory disclosure to the media, loss of existing or new customers, significant increases in the cost of managing and remediating privacy or security incidents and material fines, penalties and litigation awards, among other consequences, any of which could have a material and adverse effect on our results of operations, financial position and cash flows. Our businesses providing pharmacy care services face regulatory and operational risks and uncertainties that may differ from the risks of our other businesses. We provide pharmacy care services through our OptumRx and UnitedHealthcare businesses. Each business is subject to federal and state anti-kickback and other laws that govern the relationships of the business with pharmaceutical manufacturers, physicians, pharmacies, customers and consumers. OptumRx also conducts business through home delivery and specialty pharmacies, which subjects it to extensive federal, state and local laws and regulations, including those of the DEA and individual state controlled substance authorities. In addition, federal and state legislatures regularly consider new regulations for the industry that could materially and adversely affect current industry practices, including potential new regulations regarding the receipt or disclosure of rebates from pharmaceutical companies, the development and use of formularies, the use of average wholesale prices or other pricing benchmarks, pricing for specialty pharmaceuticals and pharmacy network reimbursement methodologies. Our pharmacy care services businesses would be materially and adversely affected by our inability to contract on favorable terms with pharmaceutical manufacturers and other suppliers, and could face potential claims in connection with purported errors by our home delivery or specialty pharmacies, including in connection with the risks inherent in the packaging and distribution of pharmaceuticals and other health care products. Disruptions at any of our home delivery or specialty pharmacies due to an accident or an event that is beyond our control could affect our ability to process and dispense prescriptions in a timely manner and could materially and adversely affect our results of operations, financial position and cash flows. In addition, our pharmacy care services businesses provide services to sponsors of health benefit plans that are subject to ERISA. A private party or the DOL, which is the agency that enforces ERISA, could assert that the 21 fiduciary obligations imposed by the statute apply to some or all of the services provided by our pharmacy care services businesses even where our pharmacy care services businesses are not contractually obligated to assume fiduciary obligations. In the event a court were to determine that fiduciary obligations apply to our pharmacy care services businesses in connection with services for which our pharmacy care services businesses are not contractually obligated to assume fiduciary obligations, we could be subject to claims for breaches of fiduciary obligations or claims that we entered into certain prohibited transactions. If we fail to compete effectively to maintain or increase our market share, including maintaining or increasing enrollments in businesses providing health benefits, our results of operations, financial position and cash flows could be materially and adversely affected. Our businesses compete throughout the United States, Brazil and other foreign markets and face significant competition in all of the geographic markets in which we operate. In particular markets, our competitors, compared to us, may have greater capabilities, resources or market share; a more established reputation; superior supplier or health care professional arrangements; better existing business relationships; lower profit margin or financial return expectations; or other factors that give such competitors a competitive advantage. In addition, our competitive position may be adversely affected by significant merger and acquisition activity that has occurred in the industries in which we operate, both among our competitors and suppliers (including hospitals, physician groups and other care professionals). Consolidation may make it more difficult for us to retain or increase our customer base, improve the terms on which we do business with our suppliers, or maintain or increase profitability. Additionally, new direct-to-consumer business models from competing businesses may make it more difficult for us to directly engage consumers in the selection and management of their health care benefits, health care usage, and in the effective navigation of the health care system we may be challenged by new technologies and market entrants that could disrupt our existing relationship with health plan enrollees in these areas. Our business, results of operations, financial position and cash flows could be materially and adversely affected if we do not compete effectively in our markets, if we set rates too high or too low in highly competitive markets, if we do not design and price our products properly and competitively, if we are unable to innovate and deliver products and services that demonstrate value to our customers, if we do not provide a satisfactory level of services, if membership or demand for other services does not increase as we expect or declines, or if we lose accounts with more profitable products while retaining or increasing membership in accounts with less profitable products. If we fail to develop and maintain satisfactory relationships with physicians, hospitals and other service providers, our business could be materially and adversely affected. Our results of operations and prospects are substantially dependent on our continued ability to contract with physicians, hospitals, pharmaceutical benefit service providers, pharmaceutical manufacturers and other service providers at competitive prices. Any failure to develop and maintain satisfactory relationships with health care providers, whether in-network or out-of-network, could materially and adversely affect our business, results of operations, financial position and cash flows. In addition, certain activities related to network design, provider participation in networks and provider payments could result in disputes that may be costly, distract managements’ attention and result in negative publicity. In any particular market, physicians and health care providers could refuse to contract, demand higher payments, or take other actions that could result in higher medical costs, less desirable products for customers or difficulty meeting regulatory or accreditation requirements. In some markets, certain health care providers, particularly hospitals, physician/hospital organizations or multi-specialty physician groups, may have significant market positions or near monopolies that could result in diminished bargaining power on our part. In addition, accountable care organizations; practice management companies (which aggregate physician practices for administrative efficiency); and other organizational structures that physicians, hospitals and other care providers choose may change the way in which these providers interact with us and may change the competitive landscape. Such organizations or groups of physicians may compete directly with us, which could adversely affect our 22 operations, and our results of operations, financial position and cash flows by impacting our relationships with these providers or affecting the way that we price our products and estimate our costs, which might require us to incur costs to change our operations. In addition, if these providers refuse to contract with us, use their market position to negotiate favorable contracts or place us at a competitive disadvantage, our ability to market products or to be profitable in those areas could be materially and adversely affected. We have capitation arrangements with some physicians, hospitals and other health care providers. Capitation arrangements limit our exposure to the risk of increasing medical costs, but expose us to risk related to the adequacy of the financial and medical care resources of the health care provider. To the extent that a capitated health care provider organization faces financial difficulties or otherwise is unable to perform its obligations under the capitation arrangement, we may be held responsible for unpaid health care claims that should have been the responsibility of the capitated health care provider and for which we have already paid the provider, under the capitation arrangement. Further, payment or other disputes between a primary care provider and specialists with whom the primary care provider contracts could result in a disruption in the provision of services to our members or a reduction in the services available to our members. Health care providers with whom we contract may not properly manage the costs of services, maintain financial solvency or avoid disputes with other providers. Any of these events could have a material adverse effect on the provision of services to our members and our operations. Some providers that render services to our members do not have contracts with us. In those cases, we do not have a pre-established understanding about the amount of compensation that is due to the provider for services rendered to our members. In some states, the amount of compensation due to these out-of-network providers is defined by law or regulation, but in most instances, the amount is either not defined or is established by a standard that does not clearly specify dollar terms. In some instances, providers may believe that they are underpaid for their services and may either litigate or arbitrate their dispute with us or try to recover from our members the difference between what we have paid them and the amount they charged us. The success of certain businesses, including OptumHealth and UnitedHealthcare Brazil, depend on maintaining satisfactory physician employment relationships. The physicians that practice medicine or contract with our affiliated physician organizations could terminate their provider contracts or otherwise become unable or unwilling to continue practicing medicine or contracting with us. There is and will likely be heightened competition in the markets where we operate to acquire or manage physician practices or to employ or contract with individual physicians. If we are unable to maintain or grow satisfactory relationships with physicians, or to acquire, recruit or, in some instances, employ physicians, or to retain enrollees following the departure of a physician, our revenues could be materially and adversely affected. In addition, our affiliated physician organizations contract with health insurance and HMO competitors of UnitedHealthcare. Our business could suffer if our affiliated physician organizations fail to maintain relationships with these health insurance or HMO companies, or adequately price their contracts with these third-party payers. In addition, physicians, hospitals, pharmaceutical benefit service providers, pharmaceutical manufacturers and certain health care providers are customers of our Optum businesses. Given the importance of health care providers and other constituents to our businesses, failure to maintain satisfactory relationships with them could materially and adversely affect our results of operations, financial position and cash flows. We are routinely subject to various litigation actions due to the nature of our business, which could damage our reputation and, if resolved unfavorably, could result in substantial penalties or monetary damages and materially and adversely affect our results of operations, financial position and cash flows. We are routinely made party to a variety of legal actions related to, among other matters, the design, management and delivery of our product and service offerings. These matters have included or could in the future include matters related to health care benefits coverage and payment claims (including disputes with enrollees, customers and contracted and non-contracted physicians, hospitals and other health care professionals), tort claims 23 (including claims related to the delivery of health care services, such as medical malpractice by health care practitioners who are employed by us, have contractual relationships with us, or serve as providers to our managed care networks), whistleblower claims (including claims under the False Claims Act or similar statutes), contract and labor disputes, tax claims and claims related to disclosure of certain business practices. We are also party to certain class action lawsuits brought by health care professional groups and consumers. In addition, we operate in jurisdictions outside of the United States, where contractual rights, tax positions and applicable regulations may be subject to interpretation or uncertainty to a greater degree than in the United States, and therefore subject to dispute by customers, government authorities or others. We are largely self-insured with regard to litigation risks. Although we maintain excess liability insurance with outside insurance carriers for claims in excess of our self-insurance, certain types of damages, such as punitive damages in some circumstances, are not covered by insurance. Although we record liabilities for our estimates of the probable costs resulting from self-insured matters, it is possible that the level of actual losses will significantly exceed the liabilities recorded. We cannot predict the outcome of significant legal actions in which we are involved and are incurring expenses in resolving these matters. The legal actions we face or may face in the future could further increase our cost of doing business and materially and adversely affect our results of operations, financial position and cash flows. In addition, certain legal actions could result in adverse publicity, which could damage our reputation and materially and adversely affect our ability to retain our current business or grow our market share in some markets and businesses. Any failure by us to manage successfully our strategic alliances or complete, manage or integrate acquisitions and other significant strategic transactions or relationships could materially and adversely affect our business, prospects, results of operations, financial position and cash flows. As part of our business strategy, we frequently engage in discussions with third parties regarding possible investments, acquisitions, divestitures, strategic alliances, joint ventures and outsourcing transactions and often enter into agreements relating to such transactions. For example, we have a strategic alliance with AARP under which we provide AARP-branded Medicare Supplement insurance to AARP members and other AARP-branded products and services to Medicare beneficiaries. If we fail to meet the needs of our alliance or joint venture partners, including by developing additional products and services, providing high levels of service, pricing our products and services competitively or responding effectively to applicable federal and state regulatory changes, our alliances and joint ventures could be damaged or terminated, which in turn could adversely impact our reputation, business and results of operations. Further, if we fail to identify and successfully complete transactions that further our strategic objectives, we may be required to expend resources to develop products and technology internally, we may be placed at a competitive disadvantage or we may be adversely affected by negative market perceptions, any of which may have a material adverse effect on our results of operations, financial position or cash flows. Success in completing acquisitions is also dependent upon efficiently integrating the acquired business into our existing operations, including our internal control environment, or otherwise leveraging its operations, which may present challenges that are different from those presented by organic growth and that may be difficult for us to manage. If we cannot successfully integrate these acquisitions and realize contemplated revenue growth opportunities and cost savings, our business, prospects, results of operations, financial position and cash flows could be materially and adversely affected. As we expand and operate our business outside of the United States, we are presented with challenges that differ from those presented by acquisitions of domestic businesses, including challenges in adapting to new markets, business, labor and cultural practices and regulatory environments. Adapting to these challenges could require us to devote significant senior management and other resources to the acquired businesses before we realize anticipated synergies or other benefits from the acquired businesses. These challenges vary widely by country and may include political instability, government intervention, discriminatory regulation and currency exchange controls or other restrictions that could prevent us from transferring funds from these operations out of the countries in which our acquired businesses operate or converting local currencies that we hold into U.S. dollars 24 or other currencies. If we are unable to manage successfully our non-U.S. acquisitions, our business, prospects, results of operations and financial position could be materially and adversely affected. Foreign currency exchange rates and fluctuations may have an impact on our equity from period to period, which could adversely affect our debt to debt-plus-equity ratio, and our future revenues, costs and cash flows from international operations. Any measures we may implement to reduce the effect of volatile currencies may be costly or ineffective. Our sales performance will suffer if we do not adequately attract, retain and provide support to a network of independent producers and consultants. Our products and services are sold in part through independent producers and consultants with whom we do not have exclusive contracts and for whose services and allegiance we must compete intensely. Our sales would be materially and adversely affected if we were unable to attract, retain and support such independent producers and consultants or if our sales strategy is not appropriately aligned across distribution channels. Our relationships with producers could be materially and adversely impacted by changes in our business practices and the nature of our relationships to address these pressures, including potential reductions in commissions. A number of investigations have been conducted regarding the marketing practices of producers selling health care products and the payments they receive and have resulted in enforcement actions against companies in our industry and producers marketing and selling those companies’ products. If we were subjected to similar investigations and enforcement actions, they could result in penalties and the imposition of corrective action plans, which could materially and adversely impact our ability to market our products. Unfavorable economic conditions could materially and adversely affect our revenues and our results of operations. Unfavorable economic conditions may impact demand for certain of our products and services. For example, high unemployment can cause lower enrollment or lower rates of renewal in our employer group plans. Unfavorable economic conditions have also caused and could continue to cause employers to stop offering certain health care coverage as an employee benefit or elect to offer this coverage on a voluntary, employee- funded basis as a means to reduce their operating costs. In addition, unfavorable economic conditions could adversely impact our ability to increase premiums or result in the cancellation by certain customers of our products and services. These conditions could lead to a decrease in our membership levels and premium and fee revenues and could materially and adversely affect our results of operations, financial position and cash flows. During a prolonged unfavorable economic environment, state and federal budgets could be materially and adversely affected, resulting in reduced reimbursements or payments in our federal and state government health care coverage programs, including Medicare, Medicaid and CHIP. A reduction in state Medicaid reimbursement rates could be implemented retrospectively to apply to payments already negotiated or received from the government and could materially and adversely affect our results of operations, financial position and cash flows. In addition, state and federal budgetary pressures could cause the affected governments to impose new or a higher level of taxes or assessments for our commercial programs, such as premium taxes on insurance companies and HMOs and surcharges or fees on select fee-for-service and capitated medical claims. Any of these developments or actions could materially and adversely affect our results of operations, financial position and cash flows. A prolonged unfavorable economic environment also could adversely impact the financial position of hospitals and other care providers, which could materially and adversely affect our contracted rates with these parties and increase our medical costs or materially and adversely affect their ability to purchase our service offerings. Further, unfavorable economic conditions could adversely impact the customers of our Optum businesses, including health plans, HMOs, hospitals, care providers, employers and others, which could, in turn, materially and adversely affect Optum’s financial results. 25 Our investment portfolio may suffer losses, which could materially and adversely affect our results of operations, financial position and cash flows. Market fluctuations could impair our profitability and capital position. Volatility in interest rates affects our interest income and the market value of our investments in debt securities of varying maturities, which constitute the vast majority of the fair value of our investments as of December 31, 2016. Relatively low interest rates on investments, such as those experienced during recent years, have adversely impacted our investment income, and the continuation of the current low interest rate environment could further adversely affect our investment income. In addition, a delay in payment of principal or interest by issuers, or defaults by issuers (primarily from investments in corporate and municipal bonds), could reduce our investment income and require us to write down the value of our investments, which could materially and adversely affect our profitability and equity. There can be no assurance that our investments will produce total positive returns or that we will not sell investments at prices that are less than their carrying values. Changes in the value of our investment assets, as a result of interest rate fluctuations, changes in issuer financial conditions, illiquidity or otherwise, could have an adverse effect on our equity. In addition, if it became necessary for us to liquidate our investment portfolio on an accelerated basis, such an action could have a material adverse effect on our results of operations and the capital position of regulated subsidiaries. If the value of our intangible assets is materially impaired, our results of operations, equity and credit ratings could be materially and adversely affected. As of December 31, 2016, goodwill and other intangible assets had a carrying value of $56 billion, representing 46% of our total consolidated assets. We periodically evaluate our goodwill and other intangible assets to determine whether all or a portion of their carrying values may be impaired, in which case a charge to earnings may be necessary. The value of our goodwill may be materially and adversely impacted if businesses that we acquire perform in a manner that is inconsistent with our assumptions. In addition, from time to time we divest businesses, and any such divestiture could result in significant asset impairment and disposition charges, including those related to goodwill and other intangible assets. Any future evaluations requiring an impairment of our goodwill and other intangible assets could materially and adversely affect our results of operations and equity in the period in which the impairment occurs. A material decrease in equity could, in turn, adversely impact our credit ratings and potentially impact our compliance with the covenants in our bank credit facilities. If we fail to maintain properly the integrity or availability of our data or successfully consolidate, integrate, upgrade or expand our existing information systems, or if our technology products do not operate as intended, our business could be materially and adversely affected. Our ability to price adequately our products and services, to provide effective service to our customers in an efficient and uninterrupted fashion, and to report accurately our results of operations depends on the integrity of the data in our information systems. We periodically consolidate, integrate, upgrade and expand our information systems capabilities as a result of technology initiatives and recently enacted regulations, changes in our system platforms and integration of new business acquisitions. In addition, recent trends toward greater consumer engagement in health care require new and enhanced technologies, including more sophisticated applications for mobile devices. Our information systems require an ongoing commitment of significant resources to maintain, protect and enhance existing systems and develop new systems to keep pace with continuing changes in information processing technology, evolving systems and regulatory standards and changing customer preferences. If the information we rely upon to run our businesses is found to be inaccurate or unreliable or if we fail to maintain or protect our information systems and data integrity effectively, we could lose existing customers, have difficulty attracting new customers, experience problems in determining medical cost estimates and establishing appropriate pricing, have difficulty preventing, detecting and controlling fraud, have disputes with customers, physicians and other health care professionals, become subject to regulatory sanctions or penalties, incur increases in operating expenses or suffer other adverse consequences. Our process of 26 consolidating the number of systems we operate, upgrading and expanding our information systems capabilities, enhancing our systems and developing new systems to keep pace with continuing changes in information processing technology may not be successful. Failure to protect, consolidate and integrate our systems successfully could result in higher than expected costs and diversion of management’s time and energy, which could materially and adversely affect our results of operations, financial position and cash flows. Certain of our businesses sell and install software products that may contain unexpected design defects or may encounter unexpected complications during installation or when used with other technologies utilized by the customer. Connectivity among competing technologies is becoming increasingly important in the health care industry. A failure of our technology products to operate as intended and in a seamless fashion with other products could materially and adversely affect our results of operations, financial position and cash flows. Uncertain and rapidly evolving U.S. federal and state, non-U.S. and international laws and regulations related to the health information technology market may present compliance challenges and could materially and adversely affect the configuration of our information systems and platforms, and our ability to compete in this market. If we sustain cyber-attacks or other privacy or data security incidents, that result in security breaches that disrupt our operations or result in the unintended dissemination of sensitive personal information or proprietary or confidential information, we could suffer a loss of revenue and increased costs, exposure to significant liability, reputational harm and other serious negative consequences. We routinely process, store and transmit large amounts of data in our operations, including sensitive personal information as well as proprietary or confidential information relating to our business or third-parties. Some of the data we process, store and transmit may be outside of the United States due to our information technology systems and international business operations. We may be subject to breaches of the information technology systems we use. Experienced computer programmers and hackers may be able to penetrate our layered security controls and misappropriate or compromise sensitive personal information or proprietary or confidential information or that of third-parties, create system disruptions or cause shutdowns. They also may be able to develop and deploy viruses, worms and other malicious software programs that attack our systems or otherwise exploit any security vulnerabilities. Our facilities may also be vulnerable to security incidents or security attacks; acts of vandalism or theft; coordinated attacks by activist entities; misplaced or lost data; human errors; or other similar events that could negatively affect our systems and our and our customer’s data. The costs to eliminate or address the foregoing security threats and vulnerabilities before or after a cyber-incident could be significant. Our remediation efforts may not be successful and could result in interruptions, delays, or cessation of service and loss of existing or potential customers. In addition, breaches of our security measures and the unauthorized dissemination of sensitive personal information or proprietary information or confidential information about us or our customers or other third-parties, could expose our customers’ private information and our customers to the risk of financial or medical identity theft, or expose us or other third-parties to a risk of loss or misuse of this information, result in litigation and potential liability for us, damage our brand and reputation, or otherwise harm our business. If we are not able to protect our proprietary rights to our databases, software and related products, our ability to market our knowledge and information-related businesses could be hindered and our results of operations, financial position and cash flows could be materially and adversely affected. We rely on our agreements with customers, confidentiality agreements with employees and third parties, and our trademarks, trade secrets, copyrights and patents to protect our proprietary rights. These legal protections and precautions may not prevent misappropriation of our proprietary information. In addition, substantial litigation regarding intellectual property rights exists in the software industry, and we expect software products to be increasingly subject to third-party infringement claims as the number of products and competitors in this industry 27 segment grows. Such litigation and misappropriation of our proprietary information could hinder our ability to market and sell products and services and our results of operations, financial position and cash flows could be materially and adversely affected. Restrictions on our ability to obtain funds from our regulated subsidiaries could materially and adversely affect our results of operations, financial position and cash flows. Because we operate as a holding company, we are dependent upon dividends and administrative expense reimbursements from our subsidiaries to fund our obligations. Many of these subsidiaries are regulated by departments of insurance or similar regulatory authorities. We are also required by law or regulation to maintain specific prescribed minimum amounts of capital in these subsidiaries. The levels of capitalization required depend primarily upon the volume of premium revenues generated by the applicable subsidiary. In most states, we are required to seek prior approval by state regulatory authorities before we transfer money or pay dividends from our regulated subsidiaries that exceed specified amounts. An inability of our regulated subsidiaries to pay dividends to their parent companies in the desired amounts or at the time of our choosing could adversely affect our ability to reinvest in our business through capital expenditures or business acquisitions, as well as our ability to maintain our corporate quarterly dividend payment, repurchase shares of our common stock and repay our debt. If we are unable to obtain sufficient funds from our subsidiaries to fund our obligations, our results of operations, financial position and cash flows could be materially and adversely affected. Any downgrades in our credit ratings could adversely affect our business, financial condition and results of operations. Claims paying ability, financial strength and debt ratings by Nationally Recognized Statistical Rating Organizations are important factors in establishing the competitive position of insurance companies. Ratings information is broadly disseminated and generally used by customers and creditors. We believe our claims paying ability and financial strength ratings are important factors in marketing our products to certain of our customers. Our credit ratings impact both the cost and availability of future borrowings. Each of the credit rating agencies reviews its ratings periodically. Our ratings reflect each credit rating agency’s opinion of our financial strength, operating performance and ability to meet our debt obligations or obligations to policyholders. There can be no assurance that our current credit ratings will be maintained in the future. Downgrades in our credit ratings, should they occur, could materially increase our costs of or ability to access funds in the debt and capital markets and otherwise materially increase our operating costs. ITEM 1B. UNRESOLVED STAFF COMMENTS None. ITEM 2. PROPERTIES To support our business operations in the United States and other countries we own and lease real properties. Our various reportable segments use these facilities for their respective business purposes, and we believe these current facilities are suitable for their respective uses and are adequate for our anticipated future needs.

Declaration and payment of future quarterly dividends is at the discretion of the Board and may be adjusted as business needs or market conditions change. ISSUER PURCHASES OF EQUITY SECURITIES In November 1997, our Board of Directors adopted a share repurchase program, which the Board evaluates periodically. There is no established expiration date for the program. During the fourth quarter 2016, we repurchased approximately 1 million shares at an average price of $141.54 per share. As of December 31, 2016, we had Board authorization to purchase up to 51 million shares of our common stock. PERFORMANCE GRAPHS The following two performance graphs compare our total return to shareholders with the returns of indexes of other specified companies and the S&P 500 Index. The first graph compares the cumulative five-year total return to shareholders on our common stock relative to the cumulative total returns of the S&P 500 index and a customized peer group of certain Fortune 50 companies (the “Fortune 50 Group”) for the five-year period ended December 31, 2016. The second graph compares our cumulative total return to shareholders with the S&P 500 Index and an index of a group of peer companies selected by us for the five-year period ended December 31, 2016. We are not included in either the Fortune 50 Group index in the first graph or the peer group index in the second graph. In calculating the cumulative total shareholder return of the indexes, the shareholder returns of the Fortune 50 Group companies in the first graph and the peer group companies in the second graph are weighted according to the stock market capitalizations of the companies at January 1 of each year. The comparisons assume the investment of $100 on December 31, 2011 in our common stock and in each index, and that dividends were reinvested when paid. 29 Fortune 50 Group The Fortune 50 Group consists of the following companies: American International Group, Inc., Berkshire Hathaway Inc., Cardinal Health, Inc., Citigroup Inc., General Electric Company, International Business Machines Corporation and Johnson & Johnson. Although there are differences among the companies in terms of size and industry, like UnitedHealth Group, all of these companies are large multi-segment companies using a well-defined operating model in one or more broad sectors of the economy.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS The following discussion should be read together with the accompanying Consolidated Financial Statements and Notes to the Consolidated Financial Statements thereto included in Item 8, “Financial Statements.” Readers are cautioned that the statements, estimates, projections or outlook contained in this report, including discussions regarding financial prospects, economic conditions, trends and uncertainties contained in this Item 7, may constitute forward-looking statements within the meaning of the PSLRA. These forward-looking statements involve risks and uncertainties that may cause our actual results to differ materially from the expectations expressed or implied in the forward-looking statements. A description of some of the risks and uncertainties can be found further below in this Item 7 and in Part I, Item 1A, “Risk Factors.” EXECUTIVE OVERVIEW General UnitedHealth Group is a diversified health and well-being company dedicated to helping people live healthier lives and helping to make the health system work better for everyone. Through our diversified family of businesses, we leverage core competencies in advanced, enabling technology; health care data; information and intelligence; and clinical care management and coordination to help meet the demands of the health system. These core competencies are deployed within our two distinct, but strategically aligned, business platforms: health benefits operating under UnitedHealthcare and health services operating under Optum. We have four reportable segments across our two business platforms, UnitedHealthcare and Optum: • • • • UnitedHealthcare, which includes UnitedHealthcare Employer & Individual, UnitedHealthcare Medicare & Retirement, UnitedHealthcare Community & State and UnitedHealthcare Global; OptumHealth; OptumInsight; and OptumRx. Further information on our business and reportable segments is presented in Part I, Item 1, “Business” and in Note 13 of Notes to the Consolidated Financial Statements included in Part II, Item 8, “Financial Statements.” Recent Developments We have recognized in our financial results for the fourth quarter 2016 and the year ended December 31, 2016 the previously disclosed $350 million impact of our estimated share of guaranty association assessments resulting from the liquidation of Penn Treaty Network America Insurance Company and its subsidiary (Penn Treaty), following accounting, legal and regulatory consultations in connection with our 10-K filing. This charge will be funded over several years and affected by premium tax credits over time. For more detail related to the Penn Treaty liquidation, see Note 12 of Notes to the Consolidated Financial Statements included in Part II, Item 8, “Financial Statements.” Business Trends Our businesses participate in the United States, Brazilian and certain other international health markets. In the United States, health care spending has grown consistently for many years and comprises approximately 18% of gross domestic product. We expect overall spending on health care to continue to grow in the future, due to inflation, medical technology and pharmaceutical advancement, regulatory requirements, demographic trends in the population and national interest in health and well-being. The rate of market growth may be affected by a variety of factors, including macro-economic conditions and regulatory changes, which have impacted and could further impact our results of operations. 33 Pricing Trends. To price our health care benefit products, we start with our view of expected future costs. We frequently evaluate and adjust our approach in each of the local markets we serve, considering all relevant factors, such as product positioning, price competitiveness and environmental, competitive, legislative and regulatory considerations. Our review of regulatory considerations involves a focus on minimum MLR thresholds and the risk adjustment that impacts the small group and individual markets. We will continue seeking to balance growth and profitability across all of these dimensions. The commercial risk market remains highly competitive in both the small group and large group segments. We expect broad-based competition to continue as the industry adapts to individual and employer needs amid reform changes. The ACA included an annual, nondeductible insurance industry tax (Health Insurance Industry Tax) to be levied proportionally across the insurance industry for risk-based health insurance products. A provision in the 2016 Federal Budget imposes a one year moratorium for 2017 on the collection of the Health Insurance Industry Tax. Pricing for contracts that cover some portion of calendar year 2017 will reflect the impact of the moratorium. Additionally, the industry has continued to experience favorable medical cost trends due to moderated utilization, which has impacted the competitive pricing environment. Medicare Advantage funding continues to be pressured, as discussed below in “Regulatory Trends and Uncertainties.” We expect continued Medicaid revenue growth due to anticipated increases in the number of people we serve; we also believe that the payment rate environment creates the risk of downward pressure on Medicaid net margin percentages. We continue to take a prudent, market-sustainable posture for both new business and maintenance of existing relationships. We advocate for actuarially sound rates that are commensurate with our medical cost trends and we remain dedicated to partnering with those states that are committed to the long-term viability of their programs. Medical Cost Trends. Our medical cost trends primarily relate to changes in unit costs, health system utilization and prescription drug costs. We endeavor to mitigate those increases with medical management. Our 2017 management activities include managing costs across all health care categories, including specialty pharmacy spending, as new therapies are introduced at high costs and older drugs experience price increases. Delivery System and Payment Modernization. The health care market continues to change based on demographic shifts, new regulations, political forces and both payer and patient expectations. Health plans and care providers are being called upon to work together to close gaps in care and improve overall care quality, improve the health of populations and reduce costs. We continue to see a greater number of people enrolled in plans with underlying incentive-based care provider payment models that reward high-quality, affordable care and foster collaboration. We work together with clinicians to leverage our data and analytics to provide the necessary information to close gaps in care and improve overall health outcomes for patients. We are increasingly rewarding care providers for delivering improvements in quality and cost-efficiency. As of December 31, 2016, we served more than 15 million people through some form of aligned contractual arrangement, including full-risk, shared-risk and bundled episode-of-care and performance incentive payment approaches. As of December 31, 2016, our contracts with value-based elements total nearly $53 billion in annual spending. This trend is creating needs for health management services that can coordinate care around the primary care physician, including new primary care channels, and for investments in new clinical and administrative information and management systems, which we believe provide growth opportunities for our Optum business platform. Regulatory Trends and Uncertainties Following is a summary of management’s view of the trends and uncertainties related to some of the key provisions of the ACA and other regulatory matters. For additional information regarding the ACA and regulatory trends and uncertainties, see Part I, Item 1 “Business — Government Regulation” and Item 1A, “Risk Factors.” 34 Medicare Advantage Rates. Final 2017 Medicare Advantage rates resulted in an increase in industry base rates of approximately 0.85%, well short of the industry forward medical cost trend of 3%, which creates continued pressure in the Medicare Advantage program. The impact of this funding shortfall in Medicare Advantage is partially mitigated by reductions in provider payments for those care providers with rates indexed to Medicare Advantage revenues or Medicare fee-for-service payment rates. These factors can affect our plan benefit designs, pricing, growth prospects and earnings expectations for our Medicare Advantage plans. The ongoing pressure on Medicare Advantage funding places continued importance on effective medical management and ongoing improvements in administrative efficiency. There are a number of adjustments we have made to partially offset these rate pressures and reductions. In some years, these adjustments will impact the majority of the seniors we serve through Medicare Advantage. For example, we seek to intensify our medical and operating cost management, make changes to the size and composition of our care provider networks, adjust members’ benefits, implement or increase the member premiums that supplement the monthly payments we receive from the government and decide on a county-by-county basis where we will offer Medicare Advantage plans. As Medicare Advantage payments change, other products may become relatively more attractive to Medicare beneficiaries and increase the demand for other senior health benefits products such as our market-leading Medicare Supplement and stand-alone Medicare Part D insurance offerings. As provided in the ACA, our Medicare Advantage rates are currently enhanced by CMS quality bonuses in certain counties based on our local plans’ Star ratings. The level of Star ratings from CMS, based upon specified clinical and operational performance standards, will impact future quality bonuses. In addition, Star ratings affect the amount of savings a plan can use to offer supplemental benefits, which ultimately may affect the plan’s membership and revenue. For the 2016 payment year, approximately 57% of our Medicare Advantage members were in plans rated four stars or higher. We expect that at least 80% of our Medicare Advantage members will be in plans rated four stars or higher for payment year 2017. We continue to dedicate substantial resources to advance our quality scores and Star ratings to strengthen our local market programs and further improve our performance. Health Insurance Industry Tax and Premium Stabilization Programs. The industry-wide amount of the Health Insurance Industry Tax was $11.3 billion in 2016 and we paid our portion of the tax, which was $1.8 billion, in September 2016. A provision in the 2016 Federal Budget imposes a one year moratorium for 2017 on the collection of the Health Insurance Industry Tax. The Health Insurance Industry Tax is scheduled to be imposed for 2018 and beyond. In 2018, the industry-wide amount of the Health Insurance Industry Tax is expected to be $14.3 billion. The ACA also included three programs designed to stabilize the health insurance markets. These programs encompassed: a transitional reinsurance program; a temporary risk corridors program; and a permanent risk adjustment program. The transitional reinsurance and temporary risk corridors programs expired at the end of 2016. Individual Public Exchanges. In 2016, we participated in individual public exchanges in 34 states and offered individual ACA compliant products. We recorded a premium deficiency reserve for a portion of our estimated 2016 losses in our 2015 results for in-force contracts as of January 1, 2016. During 2016, we incurred additional losses in our individual ACA compliant products and, for 2017, reduced our participation to three individual public exchanges. We expect to reduce the number of consumers we serve through individual insurance plans by nearly 1 million people in 2017, which will reduce our premium revenues by more than $4 billion. 35 RESULTS SUMMARY The following table summarizes our consolidated results of operations and other financial information: (in millions, except percentages and per share data) 2016 2015 2014 2016 vs. 2015 2015 vs. 2014 For the Years Ended December 31, Change Change Revenues: Premiums . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . $144,118 $127,163 $115,302 4,242 Products . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 10,151 Services . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 779 Investment and other income . . . . . . . . . . . . . . .

SELECTED OPERATING PERFORMANCE AND OTHER SIGNIFICANT ITEMS The following represents a summary of select 2016 year-over-year operating comparisons to 2015 and other 2016 significant items. • • • • • Consolidated revenues increased by 18%, UnitedHealthcare revenues increased 13% and Optum revenues grew 24%. UnitedHealthcare grew to serve an additional 2.1 million people domestically. Earnings from operations increased by 17%, including increases of 8% at UnitedHealthcare and 32% at Optum. Diluted earnings per common share increased 21% to $7.25. Cash flows from operations were $9.8 billion. 36 2016 RESULTS OF OPERATIONS COMPARED TO 2015 RESULTS Our results of operations were affected by our acquisition of Catamaran in the third quarter of 2015. Consolidated Financial Results Revenues The increases in revenues were primarily driven by organic growth in the number of individuals served across our UnitedHealthcare benefits businesses and growth across all of our Optum services businesses. Medical Costs Medical costs increased due to risk-based membership growth and medical cost trends, partially offset by medical management initiatives. Income Tax Rate Our effective tax rate decreased primarily due to the adoption of the ASU 2016-09, which we adopted in the first quarter of 2016. See Note 2 of Notes to the Consolidated Financial Statements included in Part II, Item 8, of this report for more information about the adoption of ASU 2016-09.

Medicare Advantage increased year-over-year due to growth in people served through individual and employer-sponsored group Medicare Advantage plans. Medicaid growth was driven by the combination of new state-based awards and growth in established programs. Medicare Supplement growth reflected strong customer retention and new sales. UnitedHealthcare’s revenue increase was due to growth in the number of individuals served across its businesses and price increases for underlying medical cost trends. The increase in UnitedHealthcare’s operating earnings was due to diversified growth, offset by guaranty fund assessments recorded in the fourth quarter of 2016. For more information on these assessments, see Note 12 of Notes to the Consolidated Financial Statements included in Part II, Item 8, “Financial Statements.” Operating earnings in 2015 included the establishment of premium deficiency reserves for 2016, primarily for individual ACA compliant business. 38 Optum Total revenues and operating earnings increased as each segment reported increased revenues and earnings from operations as a result of the factors discussed below. The results by segment were as follows: OptumHealth Revenue increased at OptumHealth primarily due to growth in its health care delivery businesses as well as expansion of behavioral services into new Medicaid markets. Strong performance in business supporting UnitedHealthcare partially offset by investments in the health care delivery business drove the increase in earnings from operations. OptumInsight Revenue and earnings from operations at OptumInsight increased primarily due to growth in revenue management, business process outsourcing and technology services. OptumRx Revenue and earnings from operations at OptumRx increased primarily due to the full-year impact of Catamaran and organic growth. In 2016, OptumRx fulfilled 1.24 billion adjusted scripts compared to 932 million in 2015. 2015 RESULTS OF OPERATIONS COMPARED TO 2014 RESULTS Consolidated Financial Results Revenues The increase in revenues was primarily driven by the effect of the Catamaran acquisition and organic growth in the number of individuals served across our benefits businesses and across all of Optum’s businesses. Medical Costs Medical costs increased primarily due to risk-based membership growth in our benefits businesses. Medical costs also included losses on individual ACA compliant products related to 2015, and the establishment of premium deficiency reserves related to the 2016 policy year for anticipated future losses for in-force individual ACA compliant contracts and a new state Medicaid contract. Operating Cost Ratio The decrease in our operating cost ratio was due to the inclusion of Catamaran and growth in government benefits programs, both of which have lower operating cost ratios and Company wide productivity gains. Reportable Segments UnitedHealthcare UnitedHealthcare’s revenue growth during the year ended December 31, 2015 was due to growth in the number of individuals served across its businesses and price increases reflecting underlying medical cost trends. UnitedHealthcare’s operating earnings for the year ended December 31, 2015 decreased as the combined individual ACA compliant losses and premium deficiency reserves totaling $815 million more than offset strong growth across the business, improved medical cost management and increased productivity. 39 Optum Total revenues and operating earnings increased for the year ended December 31, 2015 as each reporting segment increased revenues and earnings from operations by double-digit percentages as a result of the factors discussed below. The results by segment were as follows: OptumHealth Revenue and earnings from operations increased at OptumHealth during the year ended December 31, 2015 primarily due to growth in its care delivery businesses and the impact of acquisitions in patient care centers and population health management services. The operating margins for the year ended December 31, 2015 decreased from the prior year primarily due to investments made to develop future growth opportunities. OptumInsight Revenue, earnings from operations and operating margins at OptumInsight for the year ended December 31, 2015 increased primarily due to expansion and growth in care provider revenue management services and payer services. OptumRx Revenue and earnings from operations for the year ended December 31, 2015 increased due to the mid-year acquisition of Catamaran as well as strong organic growth. Operating margins for the year ended December 31, 2015 decreased slightly due to the inclusion of lower margin Catamaran business. LIQUIDITY, FINANCIAL CONDITION AND CAPITAL RESOURCES Liquidity Introduction We manage our liquidity and financial position in the context of our overall business strategy. We continually forecast and manage our cash, investments, working capital balances and capital structure to meet the short-term and long-term obligations of our businesses while seeking to maintain liquidity and financial flexibility. Cash flows generated from operating activities are principally from earnings before noncash expenses. Our regulated subsidiaries generate significant cash flows from operations and are subject to financial regulations and standards in their respective jurisdictions. These standards, among other things, require these subsidiaries to maintain specified levels of statutory capital, as defined by each jurisdiction, and restrict the timing and amount of dividends and other distributions that may be paid to their parent companies. In 2016, our U.S. regulated subsidiaries paid their parent companies dividends of $3.9 billion. For the year ended December 31, 2015, our U.S. regulated subsidiaries paid their parent companies dividends of $4.4 billion. See Note 10 of Notes to the Consolidated Financial Statements included in Part II, Item 8, “Financial Statements” for further detail concerning our regulated subsidiary dividends. Our nonregulated businesses also generate cash flows from operations that are available for general corporate use. Cash flows generated by these entities, combined with dividends from our regulated entities and financing through the issuance of long-term debt as well as issuance of commercial paper or the ability to draw under our committed credit facilities, further strengthen our operating and financial flexibility. We use these cash flows to expand our businesses through acquisitions, reinvest in our businesses through capital expenditures, repay debt and return capital to our shareholders through shareholder dividends and/or repurchases of our common stock, depending on market conditions. 40 Summary of our Major Sources and Uses of Cash and Cash Equivalents (in millions) Sources of cash: For the Years Ended December 31, Change Change 2016 2015 2014 2016 vs. 2015 2015 vs. 2014 Cash provided by operating activities . . . . . . . . .

Other significant changes in sources or uses of cash year-over-year included increased net purchases of investments in 2016 and the decreases in cash paid for acquisitions and proceeds from debt issuances due to the 2015 acquisition of Catamaran. 2015 Cash Flows Compared to 2014 Cash Flows Cash flows provided by operating activities in 2015 increased primarily due to growth in risk-based products, which increased medical costs payable and an increase in CMS risk share payables, which increased other liabilities. These increases were partially offset by an increase in pharmacy rebates, which increased other receivables, the increase in the payment of the 2015 Health Insurance Industry Tax and the payment of Reinsurance Program fees in 2015. Other significant changes in sources or uses of cash year-over-year included increased cash paid for acquisitions and net debt issuances and decreased share repurchases, all due to the Catamaran acquisition. 41 Financial Condition As of December 31, 2016, our cash, cash equivalent and available-for-sale investment balances of $36.7 billion included $10.4 billion of cash and cash equivalents (of which approximately $700 million was available for general corporate use), $24.2 billion of debt securities and $2.0 billion of investments in equity securities consisting of investments in non-U.S. dollar fixed-income funds; employee savings plan related investments; venture capital funds; and dividend paying stocks. Given the significant portion of our portfolio held in cash equivalents, we do not anticipate fluctuations in the aggregate fair value of our financial assets to have a material impact on our liquidity or capital position. Other sources of liquidity, primarily from operating cash flows and our commercial paper program, which is supported by our bank credit facilities, reduce the need to sell investments during adverse market conditions. See Note 4 of Notes to the Consolidated Financial Statements included in Part II, Item 8, “Financial Statements” for further detail concerning our fair value measurements. Our available-for-sale debt portfolio had a weighted-average duration of 3.3 years and a weighted-average credit rating of “AA” as of December 31, 2016. When multiple credit ratings are available for an individual security, the average of the available ratings is used to determine the weighted-average credit rating. Capital Resources and Uses of Liquidity In addition to cash flows from operations and cash and cash equivalent balances available for general corporate use, our capital resources and uses of liquidity are as follows: Commercial Paper and Bank Credit Facilities. Our revolving bank credit facilities provide liquidity support for our commercial paper borrowing program, which facilitates the private placement of senior unsecured debt through third-party broker-dealers, and are available for general corporate purposes. For more information on our commercial paper and bank credit facilities, see Note 8 of Notes to the Consolidated Financial Statements included in Part II, Item 8, “Financial Statements.” Our revolving bank credit facilities contain various covenants, including covenants requiring us to maintain a defined debt to debt-plus-shareholders’ equity ratio of not more than 55%. As of December 31, 2016, our debt to debt-plus-shareholders’ equity ratio, as defined and calculated under the credit facilities was approximately 44%. Long-Term Debt. Periodically, we access capital markets to issue long-term debt for general corporate purposes, such as, to meet our working capital requirements, to refinance debt, to finance acquisitions or for share repurchases. In February 2016, we issued debt to repay commercial paper borrowings, which were incurred for general corporate and working capital purposes, and to repay our 5.375% notes that were due March 15, 2016. In December 2016, we issued debt to repay commercial paper borrowings, which were incurred for general corporate and working capital purposes. For more information on these debt issuances, see Note 8 of Notes to the Consolidated Financial Statements included in Part II, Item 8 “Financial Statements.” Credit Ratings. Our credit ratings as of December 31, 2016 were as follows: Moody’s Standard & Poor’s Fitch A.M. Best Ratings Outlook Ratings Outlook Ratings Outlook Ratings Outlook Senior unsecured debt . . . . . . . . Commercial paper . . . . . . . . . . . A3 P-2 Negative n/a A+ A-1 Negative n/a A- F1 Negative n/a bbb+ AMB-2 Stable n/a The availability of financing in the form of debt or equity is influenced by many factors, including our profitability, operating cash flows, debt levels, credit ratings, debt covenants and other contractual restrictions, regulatory requirements and economic and market conditions. For example, a significant downgrade in our credit ratings or adverse conditions in the capital markets may increase the cost of borrowing for us or limit our access to capital. 42 Share Repurchase Program. As of December 31, 2016, we had Board authorization to purchase up to an additional 51 million shares of our common stock. For more information on our share repurchase program, see Note 10 of Notes to the Consolidated Financial Statements included in Part II, Item 8, “Financial Statements.” Dividends. In June 2016, our Board increased our quarterly cash dividend to shareholders to an annual dividend rate of $2.50 per share. For more information on our dividend, see Note 10 of Notes to the Consolidated Financial Statements included in Part II, Item 8, “Financial Statements.” CONTRACTUAL OBLIGATIONS AND COMMITMENTS The following table summarizes future obligations due by period as of December 31, 2016, under our various contractual obligations and commitments: (in millions) 2017 2018 to 2019 2020 to 2021 Thereafter Total Debt (a) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

The table also assumes amounts are outstanding through their contractual term. See Note 8 of Notes to the Consolidated Financial Statements included in Part II, Item 8, “Financial Statements” for more detail. Includes fixed or minimum commitments under existing purchase obligations for goods and services, including agreements that are cancelable with the payment of an early termination penalty and remaining capital commitments for venture capital funds and other funding commitments. Excludes agreements that are cancelable without penalty and excludes liabilities to the extent recorded in our Consolidated Balance Sheets as of December 31, 2016. (c) Future policy benefits represent account balances that accrue to the benefit of the policyholders, excluding surrender charges, for universal life and investment annuity products and for long-duration health policies sold to individuals for which some of the premium received in the earlier years is intended to pay benefits to be incurred in future years. See Note 2 of Notes to the Consolidated Financial Statements included in Part II, Item 8, “Financial Statements” for more detail. (d) As the timing of future settlements is uncertain, the long-term portion has been classified as “Thereafter.” Includes obligations associated with contingent consideration and other payments related to business (e) acquisitions, certain employee benefit programs, amounts accrued for guaranty fund assessments and various other long-term liabilities. Due to uncertainty regarding payment timing, obligations for employee benefit programs, charitable contributions and other liabilities have been classified as “Thereafter.” Includes commitments for redeemable shares of our subsidiaries. (f) We do not have other significant contractual obligations or commitments that require cash resources. However, we continually evaluate opportunities to expand our operations, which include internal development of new products, programs and technology applications and may include acquisitions. OFF-BALANCE SHEET ARRANGEMENTS As of December 31, 2016, we were not involved in any off-balance sheet arrangements, which have or are reasonably likely to have a material effect on our financial condition, results of operations or liquidity. 43 RECENTLY ISSUED ACCOUNTING STANDARDS See Note 2 of Notes to the Consolidated Financial Statements in Part II, Item 8 “Financial Statements” for a discussion of new accounting pronouncements that affect us. CRITICAL ACCOUNTING ESTIMATES Critical accounting estimates are those estimates that require management to make challenging, subjective or complex judgments, often because they must estimate the effects of matters that are inherently uncertain and may change in subsequent periods. Critical accounting estimates involve judgments and uncertainties that are sufficiently sensitive and may result in materially different results under different assumptions and conditions. Medical Costs Payable Medical costs and medical costs payable include estimates of our obligations for medical care services that have been rendered on behalf of insured consumers, but for which claims have either not yet been received or processed. Depending on the health care professional and type of service, the typical billing lag for services can be up to 90 days from the date of service. Approximately 90% of claims related to medical care services are known and settled within 90 days from the date of service and substantially all within twelve months. As of December 31, 2016, our days outstanding in medical payables was 51 days, calculated as total medical payables divided by total medical costs times the number of days in the period. In each reporting period, our operating results include the effects of more completely developed medical costs payable estimates associated with previously reported periods. If the revised estimate of prior period medical costs is less than the previous estimate, we will decrease reported medical costs in the current period (favorable development). If the revised estimate of prior period medical costs is more than the previous estimate, we will increase reported medical costs in the current period (unfavorable development). Medical costs in 2016, 2015 and 2014 included favorable medical cost development related to prior years of $220 million, $320 million and $420 million, respectively. In developing our medical costs payable estimates, we apply different estimation methods depending on the month for which incurred claims are being estimated. For example, for the most recent two months, we estimate claim costs incurred by applying observed medical cost trend factors to the average per member per month (PMPM) medical costs incurred in prior months for which more complete claim data is available, supplemented by a review of near-term completion factors. Completion Factors. A completion factor is an actuarial estimate, based upon historical experience and analysis of current trends, of the percentage of incurred claims during a given period that have been adjudicated by us at the date of estimation. Completion factors are the most significant factors we use in developing our medical costs payable estimates for periods prior to the most recent two months. Completion factors include judgments in relation to claim submissions such as the time from date of service to claim receipt, claim inventory levels and claim processing backlogs, as well as other factors. If actual claims submission rates from providers (which can be influenced by a number of factors, including provider mix and electronic versus manual submissions) or our claim processing patterns are different than estimated, our reserves may be significantly impacted. The following table illustrates the sensitivity of these factors and the estimated potential impact on our medical costs payable estimates for those periods as of December 31, 2016: Completion Factors (Decrease) Increase in Factors Increase (Decrease) In Medical Costs Payable (in millions) (0.75)% . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

Medical cost PMPM trend factors are significant factors we use in developing our medical costs payable estimates for the most recent two months. Medical cost trend factors are developed through a comprehensive analysis of claims incurred in prior months, provider contracting and expected unit costs, benefit design and by reviewing a broad set of health care utilization indicators, including but not limited to, pharmacy utilization trends, inpatient hospital census data and incidence data from the National Centers for Disease Control. We also consider macroeconomic variables such as gross-domestic product growth, employment and disposable income. A large number of factors can cause the medical cost trend to vary from our estimates, including: our ability and practices to manage medical and pharmaceutical costs, changes in level and mix of services utilized, mix of benefits offered, including the impact of co-pays and deductibles, changes in medical practices, catastrophes and epidemics. The following table illustrates the sensitivity of these factors and the estimated potential impact on our medical costs payable estimates for the most recent two months as of December 31, 2016: Medical Cost PMPM Trend Increase (Decrease) in Factors Increase (Decrease) In Medical Costs Payable (in millions) 3% . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 2 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

Management believes the amount of medical costs payable is reasonable and adequate to cover our liability for unpaid claims as of December 31, 2016; however, actual claim payments may differ from established estimates as discussed above. Assuming a hypothetical 1% difference between our December 31, 2016 estimates of medical costs payable and actual medical costs payable, excluding AARP Medicare Supplement Insurance and any potential offsetting impact from premium rebates, 2016 net earnings would have increased or decreased by $90 million. For more detail related to our medical cost estimates, see Note 2 of Notes to the Consolidated Financial Statements included in Part II, Item 8, “Financial Statements.” Revenues We derive a substantial portion of our revenues from health care insurance premiums. We recognize premium revenues in the period eligible individuals are entitled to receive health care services. Customers are typically billed monthly at a contracted rate per eligible person multiplied by the total number of people eligible to receive services. Our Medicare Advantage and Medicare Part D premium revenues are subject to periodic adjustment under the CMS risk adjustment payment methodology. The CMS risk adjustment model provides higher per member payments for enrollees diagnosed with certain conditions and lower payments for enrollees who are healthier. We estimate risk adjustment revenues based upon the data submitted and expected to be submitted to CMS. As a result of the variability of factors that determine such estimations, the actual amount of CMS’ retroactive payments could be materially more or less than our estimates. This may result in favorable or unfavorable adjustments to our Medicare premium revenue and, accordingly, our profitability. For more detail on premium revenues see Note 2 of Notes to the Consolidated Financial Statements included in Part II, Item 8, “Financial 45 Statements.” Risk adjustment data for certain of our plans is subject to review by the federal and state governments, including audit by regulators. See Note 12 of Notes to the Consolidated Financial Statements included in Part II, Item 8, “Financial Statements” for additional information regarding these audits. Our estimates of premiums to be recognized are reduced by any expected premium minimum MLR rebates payable by us to CMS. Goodwill and Intangible Assets Goodwill. We evaluate goodwill for impairment annually or more frequently when an event occurs or circumstances change that indicate the carrying value may not be recoverable. When testing goodwill for impairment, we may first assess qualitative factors to determine if it is more likely than not that the carrying value of a reporting unit exceeds its estimated fair value. During a qualitative analysis, we consider the impact of changes, if any, to the following factors: macroeconomic, industry and market factors, cost factors, changes in overall financial performance, and any other relevant events and uncertainties impacting a reporting unit. If our qualitative assessment indicates that goodwill impairment is more likely than not, we perform additional quantitative analysis. We may also elect to skip the qualitative testing and proceed directly to the quantitative testing. For reporting units where a quantitative analysis is performed, we perform a multi-step test measuring the fair values of the reporting units and comparing them to their aggregate carrying values, including goodwill. If the fair value is less than the carrying value of the reporting unit, then the implied value of goodwill would be calculated and compared to the carrying amount of goodwill to determine whether goodwill is impaired. We estimate the fair values of our reporting units using discounted cash flows, which include assumptions about a wide variety of internal and external factors. Significant assumptions used in the impairment analysis include financial projections of free cash flow (including significant assumptions about operations, capital requirements and income taxes), long-term growth rates for determining terminal value beyond the discretely forecasted periods and discount rates. For each reporting unit, comparative market multiples are used to corroborate the results of our discounted cash flow test. Forecasts and long-term growth rates used for our reporting units are consistent with, and use inputs from, our internal long-term business plan and strategies. Key assumptions used in these forecasts include: • Revenue trends. Key revenue drivers for each reporting unit are determined and assessed. Significant factors include: membership growth, medical trends and the impact and expectations of regulatory environments. Additional macro-economic assumptions relating to unemployment, GDP growth, interest rates and inflation are also evaluated and incorporated, as appropriate. • Medical cost trends. For further discussion of medical cost trends, see the “Medical Cost Trend” section of Executive Overview-Business Trends above and the discussion in the “Medical Costs Payable” critical accounting estimate above. Similar factors, including historical and expected medical cost trend levels, are considered in estimating our long-term medical trends at the reporting unit level. • • Operating productivity. We forecast expected operating cost levels based on historical levels and expectations of future operating cost levels. Capital levels. The operating and long-term capital requirements for each business are considered. Discount rates are determined for each reporting unit and include consideration of the implied risk inherent in their forecasts. Our most significant estimate in the discount rate determinations involves our adjustments to the peer company weighted average costs of capital that reflect reporting unit-specific factors. We have not made any adjustments to decrease a discount rate below the calculated peer company weighted average cost of capital for any reporting unit. Company-specific adjustments to discount rates are subjective and thus are difficult to measure with certainty. The passage of time and the availability of additional information regarding areas of uncertainty with respect to the reporting units’ operations could cause these assumptions to change in the future. We completed our annual impairment tests for goodwill as of October 1, 2016. All of our reporting units had fair values substantially in excess of their carrying values. 46 Intangible Assets. Our finite-lived intangible assets are subject to impairment tests when events or circumstances indicate that an asset’s (or asset group’s) carrying value may exceed its estimated fair value. Consideration is given on a quarterly basis to a number of potential impairment indicators, including: changes in the use of the assets, changes in legal or other business factors that could affect value, experienced or expected operating cash- flow deterioration or losses, adverse changes in customer populations, adverse competitive or technological advances that could impact value and other factors. Our indefinite-lived intangible assets are tested for impairment on an annual basis, or more frequently if impairment indicators exist. To determine if an indefinite-lived intangible asset is impaired, we compare its estimated fair value to its carrying value. If the carrying value exceeds its estimated fair value, an impairment would be recorded for the amount by which the carrying value exceeds its estimated fair value. Intangible assets were not impaired in 2016. Investments Our investments are principally classified as available-for-sale and are recorded at fair value. We continually monitor the difference between the cost and fair value of our investments. Other-Than-Temporary Impairment Assessment. Individual securities with fair values lower than costs are reviewed for impairment considering the following factors: our intent to sell the security or the likelihood that we will be required to sell the security before recovery of the entire amortized cost, the length of time and extent of impairment and the financial condition and near-term prospects of the issuer as well as specific events or circumstances that may influence the operations of the issuer. Other factors included in the assessment include the type and nature of the securities and their liquidity. Given the nature of our portfolio, primarily investment grade securities, historical impairments were largely market related (e.g., interest rate fluctuations) as opposed to credit related. Our large cash holdings reduce the risk that we will be required to sell a security. However, our intent to sell a security may change from period to period if facts and circumstances change. The judgments and estimates related to other-than-temporary impairment may ultimately prove to be inaccurate due to many factors, including: circumstances may change over time, industry sector and market factors may differ from expectations and estimates or we may ultimately sell a security we previously intended to hold. Our assessment of the financial condition and near-term prospects of the issuer may ultimately prove to be inaccurate as time passes and new information becomes available, including changes to current facts and circumstances, or as unknown or estimated unlikely trends develop. LEGAL MATTERS A description of our legal proceedings is presented in Note 12 of Notes to the Consolidated Financial Statements included in Part II, Item 8, “Financial Statements.” CONCENTRATIONS OF CREDIT RISK Investments in financial instruments such as marketable securities and accounts receivable may subject us to concentrations of credit risk. Our investments in marketable securities are managed under an investment policy authorized by our Board of Directors. This policy limits the amounts that may be invested in any one issuer and generally limits our investments to U.S. government and agency securities, state and municipal securities and corporate debt obligations that are investment grade. Concentrations of credit risk with respect to accounts receivable are limited due to the large number of employer groups and other customers that constitute our client base. As of December 31, 2016, there were no significant concentrations of credit risk. 47 ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK Our primary market risks are exposures to changes in interest rates that impact our investment income and interest expense and the fair value of certain of our fixed-rate investments and debt, as well as foreign currency exchange rate risk of the U.S. dollar primarily to the Brazilian real. As of December 31, 2016, we had $13.2 billion of financial assets on which the interest rates received vary with market interest rates, which may materially impact our investment income. Also as of December 31, 2016, $12.4 billion of our financial liabilities, which include commercial paper, debt and deposit liabilities, were at interest rates that vary with market rates, either directly or through the use of related interest rate swap contracts. The fair value of certain of our fixed-rate investments and debt also varies with market interest rates. As of December 31, 2016, $21.9 billion of our investments were fixed-rate debt securities and $25.2 billion of our debt was non-swapped fixed-rate term debt. An increase in market interest rates decreases the market value of fixed- rate investments and fixed-rate debt. Conversely, a decrease in market interest rates increases the market value of fixed-rate investments and fixed-rate debt. We manage exposure to market interest rates by diversifying investments across different fixed income market sectors and debt across maturities, as well as by endeavoring to match our floating-rate assets and liabilities over time, either directly or through the use of interest rate swap contracts. Unrealized gains and losses on investments in available-for-sale securities are reported in comprehensive income. The following tables summarize the impact of hypothetical changes in market interest rates across the entire yield curve by 1% point or 2% points as of December 31, 2016 and 2015 on our investment income and interest expense per annum and the fair value of our investments and debt (in millions, except percentages): Increase (Decrease) in Market Interest Rate December 31, 2016 Investment Income Per Annum (a) Interest Expense Per Annum (a) Fair Value of Financial Assets (b) Fair Value of Financial Liabilities 2% . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

(b) As of December 31, 2016 and 2015, some of our investments had interest rates below 2% so the assumed hypothetical change in the fair value of investments does not reflect the full 200 basis point reduction. We have an exposure to changes in the value of the Brazilian real to the U.S. dollar in translation of UnitedHealthcare Brazil’s operating results at the average exchange rate over the accounting period, and 48 UnitedHealthcare Brazil’s assets and liabilities at the spot rate at the end of the accounting period. The gains or losses resulting from translating foreign assets and liabilities into U.S. dollars are included in equity and comprehensive income. An appreciation of the U.S. dollar against the Brazilian real reduces the carrying value of the net assets denominated in Brazilian real. For example, as of December 31, 2016, a hypothetical 10% and 25% increase in the value of the U.S. dollar against the Brazilian real would have caused a reduction in net assets of approximately $400 million and $900 million, respectively. We manage exposure to foreign currency earnings risk by conducting our international business operations primarily in their functional currencies. As of December 31, 2016, we had $2.0 billion of investments in equity securities, consisting of investments in non-U.S. dollar fixed-income funds; employee savings plan related investments; venture capital funds; and dividend paying stocks. Valuations in non-U.S. dollar funds are subject to foreign exchange rates. Valuations in venture capital funds are subject to conditions affecting health care and technology stocks and dividend paying equities are subject to more general market conditions. 49 ITEM 8.

These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated financial statements 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 consolidated financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the consolidated financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, such consolidated financial statements present fairly, in all material respects, the financial position of UnitedHealth Group Incorporated and subsidiaries as of December 31, 2016 and 2015, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2016, in conformity with accounting principles generally accepted in the United States of America. We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the Company’s internal control over financial reporting as of December 31, 2016, based on the criteria established in Internal Control-Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 8, 2017, expressed an unqualified opinion on the Company’s internal control over financial reporting. /s/ DELOITTE & TOUCHE LLP Minneapolis, Minnesota February 8, 2017 51 UnitedHealth Group Consolidated Balance Sheets December 31, 2016 December 31, 2015 (in millions, except per share data) Assets Current assets: Cash and cash equivalents . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

Description of Business UnitedHealth Group Incorporated (individually and together with its subsidiaries, “UnitedHealth Group” and “the Company”) is a diversified health and well-being company dedicated to helping people live healthier lives and helping to make the health system work better for everyone. Through its diversified family of businesses, the Company leverages core competencies in advanced, enabling technology; health care data, information and intelligence; and clinical care management and coordination to help meet the demands of the health system. These core competencies are deployed within the Company’s two distinct, but strategically aligned, business platforms: health benefits operating under UnitedHealthcare and health services operating under Optum. 2. Basis of Presentation, Use of Estimates and Significant Accounting Policies Basis of Presentation The Company has prepared the Consolidated Financial Statements according to U.S. Generally Accepted Accounting Principles (GAAP) and has included the accounts of UnitedHealth Group and its subsidiaries. Use of Estimates These Consolidated Financial Statements include certain amounts based on the Company’s best estimates and judgments. The Company’s most significant estimates relate to estimates and judgments for medical costs payable and revenues, valuation and impairment analysis of goodwill and other intangible assets, estimates of other current liabilities and other current receivables and valuations of certain investments. Certain of these estimates require the application of complex assumptions and judgments, often because they involve matters that are inherently uncertain and will likely change in subsequent periods. The impact of any change in estimates is included in earnings in the period in which the estimate is adjusted. Revenues Premiums Premium revenues are primarily derived from risk-based health insurance arrangements in which the premium is typically at a fixed rate per individual served for a one-year period, and the Company assumes the economic risk of funding its customers’ health care and related administrative costs. Premium revenues are recognized in the period in which eligible individuals are entitled to receive health care benefits. Health care premium payments received from the Company’s customers in advance of the service period are recorded as unearned revenues. Fully insured commercial products of U.S. health plans, Medicare Advantage and Medicare Prescription Drug Benefit (Medicare Part D) plans with medical loss ratios as calculated under the definitions in the Patient Protection and Affordable Care Act (ACA) and related federal and state regulations and implementing regulations, that fall below certain targets are required to rebate ratable portions of their premiums annually. Medicare Advantage premium revenue includes the impact of Centers for Medicare & Medicaid Services (CMS) quality bonuses based on plans’ Star ratings. Premium revenues are recognized based on the estimated premiums earned net of projected rebates because the Company is able to reasonably estimate the ultimate premiums of these contracts. The Company also records premium revenues from capitation arrangements at its OptumHealth businesses. 57 The Company’s Medicare Advantage and Medicare Part D premium revenues are subject to periodic adjustment under CMS’ risk adjustment payment methodology. CMS deploys a risk adjustment model that apportions premiums paid to all health plans according to health severity and certain demographic factors. The CMS risk adjustment model provides higher per member payments for enrollees diagnosed with certain conditions and lower payments for enrollees who are healthier. Under this risk adjustment methodology, CMS calculates the risk adjusted premium payment using diagnosis data from hospital inpatient, hospital outpatient and physician treatment settings. The Company and health care providers collect, capture and submit the necessary and available diagnosis data to CMS within prescribed deadlines. The Company estimates risk adjustment revenues based upon the diagnosis data submitted and expected to be submitted to CMS. Risk adjustment data for certain of the Company’s plans are subject to review by the government, including audit by regulators. See Note 12 for additional information regarding these audits. Products and Services For the Company’s OptumRx pharmacy care services business, the majority of revenues are derived from products sold through a contracted network of retail pharmacies or home delivery and specialty pharmacy facilities. Product revenues include ingredient costs (net of rebates), a negotiated dispensing fee and customer co-payments for drugs dispensed through the Company’s mail-service pharmacy. In retail pharmacy transactions, revenues recognized exclude the member’s applicable co-payment. Pharmacy products are billed to customers based on the number of transactions occurring during the billing period. Product revenues are recognized when the prescriptions are dispensed through the retail network or received by consumers through the Company’s mail-service pharmacy. The Company has entered into contracts in which it is primarily obligated to pay its network pharmacy providers for benefits provided to their customers regardless of whether the Company is paid. The Company is also involved in establishing the prices charged by retail pharmacies, determining which drugs will be included in formulary listings and selecting which retail pharmacies will be included in the network offered to plan sponsors’ members. As a result, revenues are reported on a gross basis. Services revenue consists of fees derived from services performed for customers that self-insure the health care costs of their employees and employees’ dependents. Under service fee contracts, the Company receives monthly, a fixed fee per employee, which is recognized as revenue as the Company performs, or makes available the applicable services to the customer. The customers retain the risk of financing health care costs for their employees and employees’ dependents, and the Company administers the payment of customer funds to physicians and other health care professionals from customer-funded bank accounts. As the Company has neither the obligation for funding the health care costs, nor the primary responsibility for providing the medical care, the Company does not recognize premium revenue and medical costs for these contracts in its Consolidated Financial Statements. For these fee-based customer arrangements, the Company provides coordination and facilitation of medical services; transaction processing; customer, consumer and care professional services; and access to contracted networks of physicians, hospitals and other health care professionals. These services are performed throughout the contract period. Revenues are also comprised of a number of services and products sold through Optum. For its financial services offerings, OptumHealth charges fees and earns investment income on managed funds. OptumInsight provides software and information products, advisory consulting arrangements and services outsourcing contracts, which may be delivered over several years. OptumInsight revenues are generally recognized over time on either a time and materials basis, or ratably as services are performed or made available to customers. Medical Costs and Medical Costs Payable The Company’s estimate of medical costs payable represents management’s best estimate of its liability for unpaid medical costs as of December 31, 2016. Each period, the Company re-examines previously established medical costs payable estimates based on actual claim submissions and other changes in facts and circumstances. As more complete claim information becomes 58 available, the Company adjusts the amount of the estimates and includes the changes in estimates in medical costs in the period in which the change is identified. Approximately 90% of claims related to medical care services are known and settled within 90 days from the date of service and substantially all within twelve months. Medical costs and medical costs payable include estimates of the Company’s obligations for medical care services that have been rendered on behalf of insured consumers, but for which claims have either not yet been received, processed, or paid. The Company develops estimates for medical care services incurred but not reported (IBNR), which includes estimates for claims that have not been received or fully processed, using an actuarial process that is consistently applied, centrally controlled and automated. The actuarial models consider factors such as time from date of service to claim processing, seasonal variances in medical care consumption, health care professional contract rate changes, medical care utilization and other medical cost trends, membership volume and demographics, the introduction of new technologies, benefit plan changes, and business mix changes related to products, customers and geography. In developing its medical costs payable estimates, the Company applies different estimation methods depending on which incurred claims are being estimated. For the most recent two months, the Company estimates claim costs incurred by applying observed medical cost trend factors to the average per member per month (PMPM) medical costs incurred in prior months for which more complete claim data are available, supplemented by a review of near-term completion factors (actuarial estimates, based upon historical experience and analysis of current trends, of the percentage of incurred claims during a given period that have been adjudicated by the Company at the date of estimation). For months prior to the most recent two months, the Company applies the completion factors to actual claims adjudicated-to-date to estimate the expected amount of ultimate incurred claims for those months. Cost of Products Sold The Company’s cost of products sold includes the cost of pharmaceuticals dispensed to unaffiliated customers either directly at its mail and specialty pharmacy locations, or indirectly through its nationwide network of participating pharmacies. Rebates attributable to non-affiliated clients are accrued as rebates receivable and a reduction of cost of products sold with a corresponding payable for the amounts of the rebates to be remitted to those non-affiliated clients in accordance with their contracts and recorded in the Consolidated Statements of Operations as a reduction of product revenue. Cost of products sold also includes the cost of personnel to support the Company’s transaction processing services, system sales, maintenance and professional services. Cash, Cash Equivalents and Investments Cash and cash equivalents are highly liquid investments that have an original maturity of three months or less. The fair value of cash and cash equivalents approximates their carrying value because of the short maturity of the instruments. Investments with maturities of less than one year are classified as short-term. Because of regulatory requirements, certain investments are included in long-term investments regardless of their maturity date. The Company classifies these investments as held-to-maturity and reports them at amortized cost. Substantially all other investments are classified as available-for-sale and reported at fair value based on quoted market prices, where available. The Company excludes unrealized gains and losses on investments in available-for-sale securities from net earnings and reports them as comprehensive income and, net of income tax effects, as a separate component of equity. To calculate realized gains and losses on the sale of investments, the Company specifically identifies the cost of each investment sold. 59 The Company evaluates an investment for impairment by considering the length of time and extent to which market value has been less than cost or amortized cost, the financial condition and near-term prospects of the issuer as well as specific events or circumstances that may influence the operations of the issuer and the Company’s intent to sell the security or the likelihood that it will be required to sell the security before recovery of the entire amortized cost. New information and the passage of time can change these judgments. The Company manages its investment portfolio to limit its exposure to any one issuer or market sector, and largely limits its investments to investment grade quality. Securities downgraded below policy minimums after purchase will be disposed of in accordance with the Company’s investment policy. Assets Under Management The Company provides health insurance products and services to members of AARP under a Supplemental Health Insurance Program (the AARP Program) and to AARP members and non-members under separate Medicare Advantage and Medicare Part D arrangements. The products and services under the AARP Program include supplemental Medicare benefits, hospital indemnity insurance, including insurance for individuals between 50 to 64 years of age and other related products. Pursuant to the Company’s agreement, AARP Program assets are managed separately from the Company’s general investment portfolio and are used to pay costs associated with the AARP Program. These assets are invested at the Company’s discretion, within investment guidelines approved by AARP. The Company does not guarantee any rates of return on these investments and, upon any transfer of the AARP Program contract to another entity, the Company would transfer cash equal in amount to the fair value of these investments at the date of transfer to that entity. Because the purpose of these assets is to fund the medical costs payable, the rate stabilization fund (RSF) liabilities and other related liabilities associated with this AARP contract, assets under management are classified as current assets, consistent with the classification of these liabilities. The effects of changes in other balance sheet amounts associated with the AARP Program also accrue to the overall benefit of the AARP policyholders through the RSF balance. Accordingly, the Company excludes the effect of such changes in its Consolidated Statements of Cash Flows. Other Current Receivables Other current receivables include amounts due from pharmaceutical manufacturers for rebates and Medicare Part D drug discounts and other miscellaneous amounts due to the Company. The Company’s pharmacy care services businesses contract with pharmaceutical manufacturers, some of which provide rebates based on use of the manufacturers’ products by its affiliated and non-affiliated clients. The Company accrues rebates as they are earned by its clients on a monthly basis based on the terms of the applicable contracts, historical data and current estimates. The pharmacy care services businesses bill these rebates to the manufacturers on a monthly or quarterly basis depending on the contractual terms and records rebates attributable to affiliated clients as a reduction to medical costs. The Company generally receives rebates from two to five months after billing. As of December 31, 2016 and 2015, total pharmaceutical manufacturer rebates receivable included in other receivables in the Consolidated Balance Sheets amounted to $3.3 billion and $2.6 billion, respectively. For details on the Company’s Medicare Part D receivables see “Medicare Part D Pharmacy Benefits” below. 60 Medicare Part D Pharmacy Benefits The Company serves as a plan sponsor offering Medicare Part D prescription drug insurance coverage under contracts with CMS. Under the Medicare Part D program, there are seven separate elements of payment received by the Company during the plan year. These payment elements are as follows: • CMS Premium. CMS pays a fixed monthly premium per member to the Company for the entire plan year. • Member Premium. Additionally, certain members pay a fixed monthly premium to the Company for the entire plan year. • • • • • Low-Income Premium Subsidy. For qualifying low-income members, CMS pays some or all of the member’s monthly premiums to the Company on the member’s behalf. Catastrophic Reinsurance Subsidy. CMS pays the Company a cost reimbursement estimate monthly to fund the CMS obligation to pay approximately 80% of the costs incurred by individual members in excess of the individual annual out-of-pocket maximum. A settlement is made with CMS based on actual cost experience, after the end of the plan year. Low-Income Member Cost Sharing Subsidy. For qualifying low-income members, CMS pays on the member’s behalf some or all of a member’s cost sharing amounts, such as deductibles and coinsurance. The cost sharing subsidy is funded by CMS through monthly payments to the Company. The Company administers and pays the subsidized portion of the claims on behalf of CMS, and a settlement payment is made between CMS and the Company based on actual claims and premium experience, after the end of the plan year. CMS Risk-Share. Premiums from CMS are subject to risk corridor provisions that compare costs targeted in the Company’s annual bids by product and region to actual prescription drug costs, limited to actual costs that would have been incurred under the standard coverage as defined by CMS. Variances of more than 5% above or below the original bid submitted by the Company may result in CMS making additional payments to the Company or require the Company to refund to CMS a portion of the premiums it received. The Company estimates and recognizes an adjustment to premium revenues related to the risk corridor payment settlement based upon pharmacy claims experience to date. The estimate of the settlement associated with these risk corridor provisions requires the Company to consider factors that may not be certain, including estimates of eligible pharmacy costs and member eligibility status differences with CMS. The Company records risk-share adjustments to premium revenues in the Consolidated Statements of Operations and other current liabilities or other current receivables in the Consolidated Balance Sheets. Drug Discount. The ACA mandated a consumer discount on brand name prescription drugs for Medicare Part D plan participants in the coverage gap. This discount is funded by CMS and pharmaceutical manufacturers while the Company administers the application of these funds. Accordingly, amounts received are not reflected as premium revenues, but rather are accounted for as deposits. The Company records a liability when amounts are received from CMS and a receivable when the Company bills the pharmaceutical manufacturers. Related cash flows are presented as customer funds administered within financing activities in the Consolidated Statements of Cash Flows. The CMS Premium, the Member Premium and the Low-Income Premium Subsidy represent payments for the Company’s insurance risk coverage under the Medicare Part D program and, therefore, are recorded as premium revenues in the Consolidated Statements of Operations. Premium revenues are recognized ratably over the period in which eligible individuals are entitled to receive prescription drug benefits. The Company records premium payments received in advance of the applicable service period in unearned revenues in the Consolidated Balance Sheets. The Catastrophic Reinsurance Subsidy and the Low-Income Member Cost Sharing Subsidy (Subsidies) represent cost reimbursements under the Medicare Part D program. Amounts received for these Subsidies are not reflected as premium revenues, but rather are accounted for as receivables and/or deposits. Related cash flows are presented as customer funds administered within financing activities in the Consolidated Statements of Cash Flows. 61 Pharmacy care costs and administrative costs under the contract are expensed as incurred and are recognized in medical costs and operating costs, respectively, in the Consolidated Statements of Operations. The final 2016 risk-share amount is expected to be settled during the second half of 2017, and is subject to the reconciliation process with CMS. The Consolidated Balance Sheets include the following amounts associated with the Medicare Part D program: (in millions) Subsidies Drug Discount Risk-Share Subsidies Drug Discount Risk-Share Other current receivables . . . . . . . . . .

Capitalized software consists of certain costs incurred in the development of internal-use software, including external direct costs of materials and services and applicable payroll costs of employees devoted to specific software development. The Company calculates depreciation and amortization using the straight-line method over the estimated useful lives of the assets. The useful lives for property, equipment and capitalized software are: Furniture, fixtures and equipment . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

Goodwill To determine whether goodwill is impaired, annually or more frequently if needed, the Company performs a multi-step impairment test. The Company may first assess qualitative factors to determine if it is more likely than not that the carrying value of a reporting unit exceeds its estimated fair value. The Company may also elect to skip the qualitative testing and proceed directly to the quantitative testing. When performing quantitative testing, the Company first estimates the fair values of its reporting units using discounted cash flows. To determine fair values, the Company must make assumptions about a wide variety of internal and external factors. Significant assumptions used in the impairment analysis include financial projections of free cash flow (including significant assumptions about operations, capital requirements and income taxes), long-term growth rates for determining terminal value and discount rates. Comparative market multiples are used to corroborate the results of the discounted cash flow test. If the fair value is less than the carrying value of the reporting unit, then the implied value of goodwill would be calculated and compared to the carrying amount of goodwill to determine whether goodwill is impaired. There was no impairment of goodwill during the year ended December 31, 2016. Intangible Assets The Company’s intangible assets are subject to impairment tests when events or circumstances indicate that an intangible asset (or asset group) may be impaired. The Company’s indefinite lived intangible assets are also tested for impairment annually. There was no impairment of intangible assets during the year ended December 31, 2016. 62 Accounts Payable and Accrued Liabilities The Company had checks outstanding of $1.5 billion and $1.6 billion as of December 31, 2016 and 2015, respectively, which were classified as accounts payable and accrued liabilities and the change in this balance has been reflected within other financing activities in the Consolidated Statements of Cash Flows. Other Current Liabilities Other current liabilities include health savings account deposits ($5.7 billion and $3.6 billion as of December 31, 2016 and 2015, respectively), the RSF associated with the AARP Program, deposits under the Medicare Part D program (see “Medicare Part D Pharmacy Benefits” above), accruals for premium rebate payments under the ACA, the current portion of future policy benefits and customer balances. Future Policy Benefits Future policy benefits represent account balances that accrue to the benefit of the policyholders, excluding surrender charges, for universal life and investment annuity products and for long-duration health policies sold to individuals for which some of the premium received in the earlier years is intended to pay benefits to be incurred in future years. Policy Acquisition Costs The Company’s short duration health insurance contracts typically have a one-year term and may be canceled by the customer with at least 30 days’ notice. Costs related to the acquisition and renewal of short duration customer contracts are charged to expense as incurred. Redeemable Noncontrolling Interests Redeemable noncontrolling interests in the Company’s subsidiaries whose redemption is outside the control of the Company are classified as temporary equity. The following table provides details of the Company’s redeemable noncontrolling interests’ activity for the years ended December 31, 2016 and 2015: (in millions) Redeemable noncontrolling interests, beginning of period . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

Restricted shares vest ratably; primarily over two to five years and compensation expense related to restricted shares is based on the share price on date of grant. Stock options and SARs vest ratably primarily over four years and may be exercised up to 10 years from the date of grant. Compensation expense related to stock options and SARs is based on the fair value at date of grant, which is estimated on the date of grant using a binomial option-pricing model. Under the Company’s Employee Stock Purchase Plan (ESPP) eligible employees are allowed to purchase the Company’s 63 stock at a discounted price, which is 85% of the lower market price of the Company’s common stock at the beginning or at the end of the six-month purchase period. Share-based compensation expense for all programs is recognized in operating costs in the Consolidated Statements of Operations. Net Earnings Per Common Share The Company computes basic earnings per common share attributable to UnitedHealth Group common shareholders by dividing net earnings attributable to UnitedHealth Group common shareholders by the weighted-average number of common shares outstanding during the period. The Company determines diluted net earnings per common share attributable to UnitedHealth Group common shareholders using the weighted-average number of common shares outstanding during the period, adjusted for potentially dilutive shares associated with stock options, SARs, restricted shares and the ESPP, (collectively, common stock equivalents) using the treasury stock method. The treasury stock method assumes a hypothetical issuance of shares to settle the share-based awards, with the assumed proceeds used to purchase common stock at the average market price for the period. Assumed proceeds include the amount the employee must pay upon exercise and any unrecognized compensation cost. The difference between the number of shares assumed issued and number of shares assumed purchased represents the dilutive shares. Health Insurance Industry Tax The ACA includes an annual, nondeductible insurance industry tax (Health Insurance Industry Tax) to be levied proportionally across the insurance industry for risk-based health insurance products. The Company estimates its liability for the Health Insurance Industry Tax based on a ratio of the Company’s applicable net premiums written compared to the U.S. health insurance industry total applicable net premiums, both for the previous calendar year. The Company records in full the estimated liability for the Health Insurance Industry Tax at the beginning of the calendar year with a corresponding deferred cost that is amortized to operating costs on the Consolidated Statements of Operations using a straight-line method of allocation over the calendar year. The liability is recorded in accounts payable and accrued liabilities and the corresponding deferred cost is recorded in prepaid expenses and other current assets on the Consolidated Balance Sheets. A provision in the 2016 Federal Budget imposed a one year moratorium for 2017 on the collection of the Health Insurance Industry Tax. Premium Stabilization Programs The ACA included three programs designed to stabilize health insurance markets (Premium Stabilization Programs): a permanent risk adjustment program; a temporary risk corridors program; and a transitional reinsurance program (Reinsurance Program). The risk-adjustment provisions apply to market reform compliant individual and small group plans in the commercial markets. Under the program, each covered member is assigned a risk score based upon demographic information and applicable diagnostic codes from the current year paid claims, in order to determine an average risk score for each plan in a particular state and market risk pool. Generally, a plan with a risk score that is less than the state’s average risk score will pay into the pool, while a plan with a risk score that is greater than the state’s average will receive money from the pool. The temporary risk corridors provisions are intended to limit the gains and losses of individual and small group qualified health plans. Plans are required to calculate the U.S. Department of Health and Human Services (HHS) risk corridor ratio of allowable costs to the defined target amount. Qualified health plans with ratios below 97% are required to make payments to HHS, while plans with ratios greater than 103% expect to receive funds from HHS. The Reinsurance Program and temporary risk corridors program expired at the end of 2016. For the Premium Stabilization Programs, the Company records a receivable or payable as an adjustment to premium revenue based on year-to-date experience when the amounts are reasonably estimable and collection is reasonably assured. Final adjustments or recoverable amounts to the Premium Stabilization Programs are determined by HHS in the year following the policy year. 64 Recently Issued Accounting Standards In February 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standard Update (ASU) No. 2016-02, “Leases (Topic 842)” (ASU 2016-02). Under ASU 2016-02, an entity will be required to recognize assets and liabilities for the rights and obligations created by leases on the entity’s balance sheet for both finance and operating leases. For leases with a term of 12 months or less, an entity can elect to not recognize lease assets and lease liabilities and expense the lease over a straight-line basis for the term of the lease. ASU 2016-02 will require new disclosures that depict the amount, timing, and uncertainty of cash flows pertaining to an entity’s leases. Companies are required to adopt the new standard using a modified retrospective approach for annual and interim periods beginning after December 15, 2018. Early adoption of ASU 2016-02 is permitted. When adopted, the Company does not expect ASU 2016-02 to have a material impact on its results of operations, equity or cash flows. The impact of ASU 2016-02 on the Company’s consolidated financial position will be based on leases outstanding at the time of adoption. In January 2016, the FASB issued ASU 2016-01, “Financial Instruments — Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities” (ASU 2016-01). The new guidance changes the current accounting related to (i) the classification and measurement of certain equity investments, (ii) the presentation of changes in the fair value of financial liabilities measured under the fair value option that are due to instrument-specific credit risk, and (iii) certain disclosures associated with the fair value of financial instruments. Most notably, ASU 2016-01 requires that equity investments, with certain exemptions, be measured at fair value with changes in fair value recognized in net income as opposed to other comprehensive income. The new guidance is effective for annual and interim reporting periods beginning after December 15, 2017. As of December 31, 2016, based on equity securities held, the Company does not expect ASU 2016-01 to have a material impact on its consolidated financial position, results of operations, equity or cash flows. The Company will continue to evaluate any changes in its mix of investments or market conditions and the related impact of ASU 2016-01. In May 2014, the FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers (Topic 606)” (ASU 2014-09) as modified by ASU No. 2015-14, “Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date,” ASU 2016-08, “Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net),” ASU No. 2016-10, “Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing,” ASU No. 2016-12, “Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients,” and ASU 2016-20, “Revenue from Contracts with Customers (Topic 606): Technical Corrections and Improvements.” ASU 2014-09 will supersede existing revenue recognition standards with a single model unless those contracts are within the scope of other standards (e.g., an insurance entity’s insurance contracts). The revenue recognition principle in ASU 2014-09 is that an entity should recognize revenue to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In addition, new and enhanced disclosures will be required. Companies may adopt the new standard either using the full retrospective approach, a modified retrospective approach with practical expedients, or a cumulative effect upon adoption approach. The Company early adopted the new standard effective January 1, 2017, as allowed, using the modified retrospective approach. As the majority of the Company’s revenues are not subject to the new guidance, the adoption of ASU 2014-09 did not have a material impact on the Company’s consolidated financial position, results of operations, equity or cash flows. Recently Adopted Accounting Standards In March 2016, the FASB issued ASU No. 2016-09, “Compensation-Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting” (ASU 2016-09). ASU 2016-09 modifies several aspects of the accounting for share-based payment awards, including income tax consequences, and classification on the statement of cash flows. The Company early adopted ASU 2016-09 in the first quarter of 2016. The provisions of ASU 2016-09 related to the timing of when excess tax benefits are recognized, minimum statutory 65 withholding requirements and forfeitures were adopted using a modified retrospective transition method by means of a cumulative-effect adjustment to equity as of January 1, 2016. The provisions of ASU 2016-09 related to the recognition of excess tax benefits in the income statement and classification in the statement of cash flows were adopted prospectively and the prior periods were not retrospectively adjusted. The adoption of ASU 2016-09 did not materially impact the Company’s consolidated financial position, results of operations, equity or cash flows. In November 2015, the FASB issued ASU No. 2015-17, “Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes” (ASU 2015-17). ASU 2015-17 requires entities to present deferred tax assets and deferred tax liabilities as noncurrent on the balance sheet. Prior to the issuance of ASU 2015-17, deferred taxes were required to be presented as a net current asset or liability and a net noncurrent asset or liability. The Company adopted ASU 2015-17 on a prospective basis in the first quarter of 2016 and the prior period was not retrospectively adjusted. The adoption of ASU 2015-17 did not impact the Company’s consolidated financial position, results of operations, equity or cash flows. In May 2015, the FASB issued ASU No. 2015-09, “Financial Services — Insurance (Topic 944): Disclosures about Short-Duration Contracts” (ASU 2015-09). ASU 2015-09 requires insurance entities to provide additional disclosures about short-duration insurance liabilities, including incurred and paid medical costs information by year. The Company adopted the disclosure requirements of ASU 2015-09 and has included the new disclosures within Notes 2 and 7. In April 2015, the FASB issued ASU No. 2015-03, “Interest-Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs” (ASU 2015-03). ASU 2015-03 requires debt issuance costs to be presented as a reduction of the carrying amount of the related debt liability. Prior to the issuance of ASU 2015-03, debt issuance costs were required to be presented as an asset on the balance sheet. The Company adopted ASU 2015-03 on a retrospective basis, as required, in the first quarter of 2016. The Company reclassified $129 million and $82 million in debt issuance costs that were recorded in other assets to long-term debt, less current maturities on the Consolidated Balance Sheet as of December 31, 2015 and 2014, respectively. The Company has determined that there have been no other recently adopted or issued accounting standards that had, or will have, a material impact on its Consolidated Financial Statements. 66 3.

The Company believes that it will collect the principal and interest due on its debt securities that have an amortized cost in excess of fair value. The unrealized losses were primarily caused by interest rate increases and not by unfavorable changes in the credit quality associated with these securities. At each reporting period, the Company evaluates securities for impairment when the fair value of the investment is less than its amortized cost. The Company evaluated the underlying credit quality and credit ratings of the issuers, noting no significant deterioration since purchase. As of December 31, 2016, the Company did not have the intent to sell any of the securities in an unrealized loss position. Therefore, the Company believes these losses to be temporary. 68 The Company’s investments in equity securities consist of investments in Brazilian real denominated fixed- income funds, employee savings plan related investments, venture capital funds and dividend paying stocks. The Company evaluated its investments in equity securities for severity and duration of unrealized loss, overall market volatility and other market factors.

Fair Value Certain assets and liabilities are measured at fair value in the Consolidated Financial Statements or have fair values disclosed in the Notes to the Consolidated Financial Statements. These assets and liabilities are classified into one of three levels of a hierarchy defined by GAAP. In instances in which the inputs used to measure fair value fall into different levels of the fair value hierarchy, the fair value measurement is categorized in its entirety based on the lowest level input that is significant to the fair value measurement in its entirety. The Company’s assessment of the significance of a particular item to the fair value measurement in its entirety requires judgment, including the consideration of inputs specific to the asset or liability. The fair value hierarchy is summarized as follows: Level 1 — Quoted prices (unadjusted) for identical assets/liabilities in active markets. Level 2 — Other observable inputs, either directly or indirectly, including: • Quoted prices for similar assets/liabilities in active markets; • Quoted prices for identical or similar assets/liabilities in inactive markets (e.g., few transactions, limited information, noncurrent prices, high variability over time); • • Inputs other than quoted prices that are observable for the asset/liability (e.g., interest rates, yield curves, implied volatilities, credit spreads); and Inputs that are corroborated by other observable market data. Level 3 — Unobservable inputs that cannot be corroborated by observable market data. Transfers between levels, if any, are recorded as of the beginning of the reporting period in which the transfer occurs; there was no transfer between Levels 1, 2 or 3 of any financial assets or liabilities during the years ended December 31, 2016 or 2015. Nonfinancial assets and liabilities or financial assets and liabilities that are measured at fair value on a nonrecurring basis are subject to fair value adjustments only in certain circumstances, such as when the Company records an impairment. There were no significant fair value adjustments for these assets and liabilities recorded during the years ended December 31, 2016 or 2015. 69 The following methods and assumptions were used to estimate the fair value and determine the fair value hierarchy classification of each class of financial instrument included in the tables below: Cash and Cash Equivalents. The carrying value of cash and cash equivalents approximates fair value as maturities are less than three months. Fair values of cash equivalent instruments that do not trade on a regular basis in active markets are classified as Level 2. Debt and Equity Securities. Fair values of debt and equity securities are based on quoted market prices, where available. The Company obtains one price for each security primarily from a third-party pricing service (pricing service), which generally uses quoted or other observable inputs for the determination of fair value. The pricing service normally derives the security prices through recently reported trades for identical or similar securities, and, if necessary, makes adjustments through the reporting date based upon available observable market information. For securities not actively traded, the pricing service may use quoted market prices of comparable instruments or discounted cash flow analyses, incorporating inputs that are currently observable in the markets for similar securities. Inputs that are often used in the valuation methodologies include, but are not limited to, benchmark yields, credit spreads, default rates, prepayment speeds and nonbinding broker quotes. As the Company is responsible for the determination of fair value, it performs quarterly analyses on the prices received from the pricing service to determine whether the prices are reasonable estimates of fair value. Specifically, the Company compares the prices received from the pricing service to prices reported by a secondary pricing source, such as its custodian, its investment consultant and third-party investment advisors. Additionally, the Company compares changes in the reported market values and returns to relevant market indices to test the reasonableness of the reported prices. The Company’s internal price verification procedures and reviews of fair value methodology documentation provided by independent pricing services have not historically resulted in adjustment in the prices obtained from the pricing service. Fair values of debt securities that do not trade on a regular basis in active markets but are priced using other observable inputs are classified as Level 2. Fair value estimates for Level 1 and Level 2 equity securities are based on quoted market prices for actively traded equity securities and/or other market data for the same or comparable instruments and transactions in establishing the prices. The fair values of Level 3 investments in venture capital portfolios are estimated using a market valuation technique that relies heavily on management assumptions and qualitative observations. Under the market approach, the fair values of the Company’s various venture capital investments are computed using limited quantitative and qualitative observations of activity for similar companies in the current market. The Company’s market modeling utilizes, as applicable, transactions for comparable companies in similar industries that also have similar revenue and growth characteristics and preferences in their capital structure. Key significant unobservable inputs in the market technique include implied earnings before interest, taxes, depreciation and amortization (EBITDA) multiples and revenue multiples. Additionally, the fair values of certain of the Company’s venture capital securities are based on recent transactions in inactive markets for identical or similar securities. Significant changes in any of these inputs could result in significantly lower or higher fair value measurements. Throughout the procedures discussed above in relation to the Company’s processes for validating third-party pricing information, the Company validates the understanding of assumptions and inputs used in security pricing and determines the proper classification in the hierarchy based on that understanding. Assets Under Management. Assets under management consists of debt securities and other investments held to fund costs associated with the AARP Program and are priced and classified using the same methodologies as the Company’s investments in debt and equity securities. Other Assets. The fair values of the Company’s other assets are estimated and classified using the same methodologies as the Company’s investments in debt securities. 70 Interest Rate Swaps. Fair values of the Company’s swaps are estimated using the terms of the swaps and publicly available information, including market yield curves. Because the swaps are unique and not actively traded but are valued using other observable inputs, the fair values are classified as Level 2. Long-Term Debt. The fair values of the Company’s long-term debt are estimated and classified using the same methodologies as the Company’s investments in debt securities. The following table presents a summary of fair value measurements by level and carrying values for items measured at fair value on a recurring basis in the Consolidated Balance Sheets: Quoted Prices in Active Markets (Level 1) Other Observable Inputs (Level 2) Unobservable Inputs (Level 3) Total Fair and Carrying Value $ 10,386 $ 44 $ — $10,430 (in millions) December 31, 2016 Cash and cash equivalents . . . . . . . . . . . . . . . . . . . . . . . . . . . .

The valuation allowances primarily relate to future tax benefits on certain federal, state and non-U.S. net operating loss carryforwards. Federal net operating loss carryforwards of $74 million expire beginning in 2021 through 2036; state net operating loss carryforwards expire beginning in 2017 through 2036. Substantially all of the non-U.S. tax loss carryforwards have indefinite carryforward periods. As of December 31, 2016, the Company had $717 million of undistributed earnings from non-U.S. subsidiaries that are intended to be reinvested in non-U.S. operations. Because these earnings are considered permanently reinvested, no U.S. tax provision has been accrued related to the repatriation of these earnings. It is not practicable to estimate the amount of U.S. tax that might be payable on the eventual remittance of such earnings. 78 A reconciliation of the beginning and ending amount of unrecognized tax benefits as of December 31 is as follows: (in millions) Gross unrecognized tax benefits, beginning of period . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

The Company classifies interest and penalties associated with uncertain income tax positions as income taxes within its Consolidated Statement of Operations. During the years ended December 31, 2016, 2015 and 2014 the Company recognized $11 million, $11 million and $6 million of interest and penalties, respectively. The Company had $70 million and $59 million of accrued interest and penalties for uncertain tax positions as of December 31, 2016 and 2015, respectively. These amounts are not included in the reconciliation above. The Company currently files income tax returns in the United States, various states and non-U.S. jurisdictions. The U.S. Internal Revenue Service (IRS) has completed exams on the consolidated income tax returns for fiscal years 2015 and prior. The Company’s 2016 tax year is under advance review by the IRS under its Compliance Assurance Program. With the exception of a few states, the Company is no longer subject to income tax examinations prior to the 2010 tax year. The Brazilian federal revenue service — Secretaria da Receita Federal (SRF) may audit the Company’s Brazilian subsidiaries for a period of five years from the date on which corporate income taxes should have been paid and/or the date when the tax return was filed. 10. Shareholders’ Equity Regulatory Capital and Dividend Restrictions The Company’s regulated subsidiaries are subject to regulations and standards in their respective jurisdictions. These standards, among other things, require these subsidiaries to maintain specified levels of statutory capital, as defined by each jurisdiction, and restrict the timing and amount of dividends and other distributions that may be paid to their parent companies. In the United States, most of these regulations and standards are generally consistent with model regulations established by the National Association of Insurance Commissioners. These standards generally permit dividends to be paid from statutory unassigned surplus of the regulated subsidiary and are limited based on the regulated subsidiary’s level of statutory net income and statutory capital and surplus. These dividends are referred to as “ordinary dividends” and generally can be paid without prior regulatory approval. If the dividend, together with other dividends paid within the preceding twelve months, exceeds a specified statutory limit or is paid from sources other than earned surplus, it is generally considered an “extraordinary dividend” and must receive prior regulatory approval. For the year ended December 31, 2016, the Company’s regulated subsidiaries paid their parent companies dividends of $3.9 billion, including $3.3 billion of extraordinary dividends. For the year ended December 31, 2015, the Company’s regulated subsidiaries paid their parent companies dividends of $4.4 billion, including $1.5 billion of extraordinary dividends. As of December 31, 2016, approximately $700 million of the Company’s $10.4 billion of cash and cash equivalents was available for general corporate use. 79 The Company’s regulated subsidiaries had estimated aggregate statutory capital and surplus of approximately $17.9 billion as of December 31, 2016. The estimated statutory capital and surplus necessary to satisfy regulatory requirements of the Company’s regulated subsidiaries was approximately $10.5 billion as of December 31, 2016. Optum Bank must meet minimum requirements for Tier 1 leverage capital, Tier 1 risk-based capital, common equity Tier1 risk-based capital and total risk-based capital of the Federal Deposit Insurance Corporation (FDIC) to be considered “Well Capitalized” under the capital adequacy rules to which it is subject. At December 31, 2016, the Company believes that Optum Bank met the FDIC requirements to be considered “Well Capitalized.” Share Repurchase Program Under its Board of Directors’ authorization, the Company maintains a share repurchase program. The objectives of the share repurchase program are to optimize the Company’s capital structure and cost of capital, thereby improving returns to shareholders, as well as to offset the dilutive impact of share-based awards. Repurchases may be made from time to time in open market purchases or other types of transactions (including prepaid or structured share repurchase programs), subject to certain Board restrictions. In June 2014, the Board renewed the Company’s share repurchase program with an authorization to repurchase up to 100 million shares of its common stock. A summary of common share repurchases for the years ended December 31, 2016 and 2015 is as follows: (in millions, except per share data) Years Ended December 31, 2016 2015 Common share repurchases, shares . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

Declaration and payment of future quarterly dividends is at the discretion of the Board and may be adjusted as business needs or market conditions change. 11. Share-Based Compensation The Company’s outstanding share-based awards consist mainly of non-qualified stock options, SARs and restricted shares. As of December 31, 2016, the Company had 68 million shares available for future grants of share-based awards under the Plan. As of December 31, 2016, there were also 10 million shares of common stock available for issuance under the ESPP.

Expected volatilities are based on the historical volatility of the Company’s common stock and the implied volatility from exchange- traded options on the Company’s common stock. Expected dividend yields are based on the per share cash dividend paid by the Company. The Company uses historical data to estimate option and SAR exercises and forfeitures within the valuation model. The expected lives of options and SARs granted represents the period of time that the awards granted are expected to be outstanding based on historical exercise patterns. 81 Other Employee Benefit Plans The Company also offers a 401(k) plan for its employees. Compensation expense related to this plan was not material for 2016, 2015 and 2014. In addition, the Company maintains non-qualified, deferred compensation plans, which allow certain members of senior management and executives to defer portions of their salary or bonus and receive certain Company contributions on such deferrals, subject to plan limitations. The deferrals are recorded within long-term investments with an approximately equal amount in other liabilities in the Consolidated Balance Sheets. The total deferrals are distributable based upon termination of employment or other periods, as elected under each plan and were $672 million and $553 million as of December 31, 2016 and 2015, respectively. 12. Commitments and Contingencies The Company leases facilities and equipment under long-term operating leases that are non-cancelable and expire on various dates. Rent expense under all operating leases for the years ended December 31, 2016, 2015 and 2014 was $608 million, $555 million and $449 million, respectively. As of December 31, 2016, future minimum annual lease payments, net of sublease income, under all non-cancelable operating leases were as follows: (in millions) Future Minimum Lease Payments 2017 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 2018 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 2019 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 2020 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 2021 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

If minimum standards are not met, the Company may be financially at risk up to a stated percentage of the contracted fee or a stated dollar amount. None of the amounts accrued, paid or charged to income for service level guarantees were material as of December 31, 2016, 2015 or 2014. As of December 31, 2016, the Company had outstanding, undrawn letters of credit with financial institutions of $28 million and surety bonds outstanding with insurance companies of $1.2 billion, primarily to bond contractual performance. Legal Matters Because of the nature of its businesses, the Company is frequently made party to a variety of legal actions and regulatory inquiries, including class actions and suits brought by members, care providers, consumer advocacy organizations, customers and regulators, relating to the Company’s businesses, including management and administration of health benefit plans and other services. These matters include medical malpractice, employment, intellectual property, antitrust, privacy and contract claims and claims related to health care benefits coverage and other business practices. The Company records liabilities for its estimates of probable costs resulting from these matters where appropriate. Estimates of costs resulting from legal and regulatory matters involving the Company are inherently difficult to predict, particularly where the matters: involve indeterminate claims for monetary damages or may involve fines, penalties or punitive damages; present novel legal theories or represent a shift in regulatory policy; involve a large number of claimants or regulatory bodies; are in the early stages of the proceedings; or could 82 result in a change in business practices. Accordingly, the Company is often unable to estimate the losses or ranges of losses for those matters where there is a reasonable possibility or it is probable that a loss may be incurred. Litigation Matters California Claims Processing Matter. On January 25, 2008, the California Department of Insurance (CDI) issued an Order to Show Cause to PacifiCare Life and Health Insurance Company, a subsidiary of the Company, alleging violations of certain insurance statutes and regulations related to an alleged failure to include certain language in standard claims correspondence, timeliness and accuracy of claims processing, interest payments, care provider contract implementation, care provider dispute resolution and other related matters. Although the Company believes that CDI had never before issued a fine in excess of $8 million, CDI advocated a fine of approximately $325 million in this matter. The matter was the subject of an administrative hearing before a California administrative law judge beginning in December 2009, and in August 2013, the administrative law judge issued a nonbinding proposed decision recommending a fine of $11.5 million. The California Insurance Commissioner rejected the administrative law judge’s recommendation and on June 9, 2014, issued his own decision imposing a fine of approximately $174 million. On July 10, 2014, the Company filed a lawsuit in California state court challenging the Commissioner’s decision. On September 8, 2015, in the first phase of that lawsuit, the California state court issued an order invalidating certain of the regulations the Commissioner had relied upon in issuing his decision and penalty. The Company cannot reasonably estimate the range of loss, if any, that may result from this matter given the procedural status of the dispute, the wide range of possible outcomes, the legal issues presented (including the legal basis for the majority of the alleged violations), the inherent difficulty in predicting a regulatory fine in the event of a remand, and the various remedies and levels of judicial review that remain available to the Company. Government Investigations, Audits and Reviews The Company has been involved or is currently involved in various governmental investigations, audits and reviews. These include routine, regular and special investigations, audits and reviews by the CMS, state insurance and health and welfare departments, the Brazilian national regulatory agency for private health insurance and plans (the Agência Nacional de Saúde Suplementar), state attorneys general, the Office of the Inspector General, the Office of Personnel Management, the Office of Civil Rights, the Government Accountability Office, the Federal Trade Commission, U.S. Congressional committees, the U.S. Department of Justice, the SEC, the Internal Revenue Service, the U.S. Drug Enforcement Administration, the Brazilian federal revenue service (the Secretaria da Receita Federal), the U.S. Department of Labor, the Federal Deposit Insurance Corporation, the Defense Contract Audit Agency and other governmental authorities. Certain of the Company’s businesses have been reviewed or are currently under review, including for, among other matters, compliance with coding and other requirements under the Medicare risk-adjustment model. The Company has produced documents, information and witnesses to the Department of Justice in cooperation with a current review of the Company’s risk-adjustment processes, including the Company’s patient chart review and related programs. CMS has selected certain of the Company’s local plans for risk adjustment data validation (RADV) audits to validate the coding practices of and supporting documentation maintained by health care providers and such audits may result in retrospective adjustments to payments made to the Company’s health plans. The Company cannot reasonably estimate the range of loss, if any, that may result from any material government investigations, audits and reviews in which it is currently involved given the status of the reviews, the wide range of possible outcomes and the inherent difficulty in predicting regulatory action, fines and penalties, if any, the Company’s legal and factual defenses and the various remedies and levels of judicial review available to the Company in the event of an adverse finding. 83 Guaranty Fund Assessments Under state guaranty association laws, certain insurance companies can be assessed (up to prescribed limits) for certain obligations to the policyholders and claimants of impaired or insolvent insurance companies that write the same line or similar lines of business. Some states have similar laws relating to HMOs and other payers such as consumer operated and oriented plans (co-ops) established under the ACA. In 2009, the Pennsylvania Insurance Commissioner placed long term care insurer Penn Treaty Network America Insurance Company and its subsidiary (Penn Treaty), neither of which is affiliated with the Company, in rehabilitation and petitioned a state court for approval to liquidate Penn Treaty. In 2012, the court denied the liquidation petition and ordered the Insurance Commissioner to submit a rehabilitation plan. A second amended plan of rehabilitation was later withdrawn and, as of November 2016, Penn Treaty will be liquidated. As of December 31, 2016, the Company recorded the $350 million impact of its estimated share of guaranty association assessments resulting from the Penn Treaty liquidation. 13. Segment Financial Information Factors used to determine the Company’s reportable segments include the nature of operating activities, economic characteristics, existence of separate senior management teams and the type of information used by the Company’s chief operating decision maker to evaluate its results of operations. Reportable segments with similar economic characteristics, products and services, customers, distribution methods and operational processes that operate in a similar regulatory environment are combined. The following is a description of the types of products and services from which each of the Company’s four reportable segments derives its revenues: • • • • UnitedHealthcare includes the combined results of operations of UnitedHealthcare Employer & Individual, UnitedHealthcare Medicare & Retirement, UnitedHealthcare Community & State and UnitedHealthcare Global. The U.S. businesses share significant common assets, including a contracted network of physicians, health care professionals, hospitals and other facilities, information technology infrastructure and other resources. UnitedHealthcare Employer & Individual offers an array of consumer-oriented health benefit plans and services for large national employers, public sector employers, mid-sized employers, small businesses and individuals nationwide and active and retired military and their families through the TRICARE program. UnitedHealthcare Medicare & Retirement provides health care coverage and health and well-being services to individuals age 50 and older, addressing their unique needs for preventive and acute health care services as well as services dealing with chronic disease and other specialized issues for older individuals. UnitedHealthcare Community & State’s primary customers oversee Medicaid plans, the Children’s Health Insurance Program and other federal, state and community health care programs. UnitedHealthcare Global is a diversified global health services business with a variety of offerings, including international commercial health and dental benefits. OptumHealth serves the physical, emotional and health-related financial needs of individuals, enabling population health management through programs offered by employers, payers, government entities and directly with the care delivery system. OptumHealth offers access to networks of care provider specialists, health management services, care delivery, consumer engagement and financial services. OptumInsight provides services, technology and health care expertise to major participants in the health care industry. Hospital systems, physicians, health plans, governments, life sciences companies and other organizations that comprise the health care industry depend on OptumInsight to help them improve performance, achieve efficiency, reduce costs, meet compliance mandates and modernize their core operating systems to meet the changing needs of the health system. OptumRx offers pharmacy care services and programs, including retail network contracting, home delivery and specialty pharmacy services, purchasing and clinical capabilities, and develops programs in areas such as step therapy, formulary management, drug adherence and disease/drug therapy management. 84 The Company’s accounting policies for reportable segment operations are consistent with those described in the Summary of Significant Accounting Policies (see Note 2). Transactions between reportable segments principally consist of sales of pharmacy care products and services to UnitedHealthcare customers by OptumRx, certain product offerings and care management and local care delivery services sold to UnitedHealthcare by OptumHealth, and health information and technology solutions, consulting and other services sold to UnitedHealthcare by OptumInsight. These transactions are recorded at management’s estimate of fair value. Intersegment transactions are eliminated in consolidation. Assets and liabilities that are jointly used are assigned to each reportable segment using estimates of pro-rata usage. Cash and investments are assigned such that each reportable segment has working capital and/or at least minimum specified levels of regulatory capital. As a percentage of the Company’s total consolidated revenues, premium revenues from CMS were 25% for 2016, 26% for 2015 and 29% for 2014, most of which were generated by UnitedHealthcare Medicare & Retirement and included in the UnitedHealthcare segment. U.S. customer revenue represented approximately 97%, 96% and 95% of consolidated total revenues for 2016, 2015 and 2014, respectively. Long-lived fixed assets located in the United States represented approximately 75% and 81% of the total long-lived fixed assets as of December 31, 2016 and 2015, respectively. The non-U.S. revenues and fixed assets are primarily related to UnitedHealthcare Global. 85 The following table presents the reportable segment financial information: (in millions) UnitedHealthcare OptumHealth OptumInsight OptumRx Eliminations Optum Optum Optum Corporate and Eliminations Consolidated 2016 Revenues — external customers: Premiums . . . . . . . . . . . . . . . . . $ Products . . . . . . . . . . . . . . . . . . .

CONTROLS AND PROCEDURES EVALUATION OF DISCLOSURE CONTROLS AND PROCEDURES We maintain disclosure controls and procedures as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934 (Exchange Act) that are designed to provide reasonable assurance that information required to be disclosed by us in reports that we file or submit under the Exchange Act is (i) recorded, processed, summarized and reported within the time periods specified in SEC rules and forms; and (ii) accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding required disclosure. In connection with the filing of this Annual Report on Form 10-K, management evaluated, under the supervision and with the participation of our Chief Executive Officer and Chief Financial Officer, the effectiveness of the design and operation of our disclosure controls and procedures as of December 31, 2016. Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective at the reasonable assurance level as of December 31, 2016. CHANGES IN INTERNAL CONTROL OVER FINANCIAL REPORTING There have been no changes in our internal control over financial reporting during the quarter ended December 31, 2016 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. 87 Report of Management on Internal Control Over Financial Reporting as of December 31, 2016 UnitedHealth Group Incorporated and Subsidiaries’ (the “Company”) management is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rules 13a-15(f) and 15d-15(f) under the Securities Exchange Act of 1934. The Company’s internal control system is designed to provide reasonable assurance to our management and board of directors regarding the reliability of financial reporting and the preparation of consolidated financial statements for external purposes in accordance with generally accepted accounting principles. The Company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the Company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of consolidated 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 (iii) 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 consolidated financial statements. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. Management assessed the effectiveness of the Company’s internal control over financial reporting as of December 31, 2016. In making this assessment, we used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control-Integrated Framework (2013). Based on our assessment and the COSO criteria, we believe that, as of December 31, 2016, the Company maintained effective internal control over financial reporting. The Company’s independent registered public accounting firm has audited the Company’s internal control over financial reporting as of December 31, 2016, as stated in the Report of Independent Registered Public Accounting Firm, appearing under Item 9A. 88 Report of Independent Registered Public Accounting Firm To the Board of Directors and Shareholders of UnitedHealth Group Incorporated and Subsidiaries: We have audited the internal control over financial reporting of UnitedHealth Group Incorporated and subsidiaries (the “Company”) as of December 31, 2016, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. The Company’s management is responsible 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 Report of Management on Internal Control Over Financial Reporting as of December 31, 2016. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We conducted our audit 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 effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion. 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 Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2016, based on the criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated financial statements as of and for the year ended December 31, 2016 of the Company and our report dated February 8, 2017 expressed an unqualified opinion on those consolidated financial statements. /s/ DELOITTE & TOUCHE LLP Minneapolis, Minnesota February 8, 2017 89 ITEM 9B.
