PART I
ITEM  1.    BUSINESS
INTRODUCTION
Overview
UnitedHealth Group is a diversified health care company dedicated to helping people live healthier lives and helping 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 data and health information; advanced technology; and clinical expertise 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 the provision of 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 2017, we processed nearly three-quarters of a trillion dollars in gross billed charges and we managed nearly $250 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 care 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.”
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.

1


In the United States, UnitedHealthcare arranges for discounted access to care through networks that include 1.2 million physicians and other health care professionals and approximately 6,500 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 27 million people on behalf of our customers and alliance partners. This includes more than 230,000 employer customers serving people across all 50 states, the District of Columbia and most U.S. territories. 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 and improve quality across populations.
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. In addition, UnitedHealthcare Employer & Individual distributes its products through professional employer organizations, associations and through both multi-carrier and its own proprietary private exchange marketplaces.
UnitedHealthcare Employer & Individual’s diverse product portfolio offers employers a continuum of benefit designs, price points and approaches to consumer engagement, which provides the flexibility to meet a full spectrum of their coverage needs.
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 2017, more than 50,000 employer-sponsored benefit plans, including nearly 400 employers in the large group self-funded market, purchased HRA or HSA health benefit 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.

2


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;
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, using its network of more than 22,000 vision offices and more than 85,000 dental offices, in private and retail settings.
UnitedHealthcare Military & Veterans. UnitedHealthcare Military & Veterans was the provider of health care services for nearly 3 million active duty and retired military service members and their families under the Department of Defense’s (DoD) TRICARE Managed Care Support contract that concluded on January 1, 2018.
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.
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 the Centers for Medicare & Medicaid Services (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

3


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 4.4 million people through its Medicare Advantage products as of December 31, 2017.
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 nearly 1.3 million in-home preventive care visits in 2017 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 people at high risk and allow care managers to 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, 2017, UnitedHealthcare enrolled 8.9 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 4.9 million seniors nationwide through various Medicare Supplement products in association with AARP. UnitedHealthcare Medicare & Retirement offers a full range of supplemental products at a diversity of price points. These products cover various levels of coinsurance and deductible gaps that seniors are exposed to in the traditional Medicare program.
Premium revenues from CMS represented 28% of UnitedHealth Group’s total consolidated revenues for the year ended December 31, 2017, 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, 2017, UnitedHealthcare Community & State participated in programs in 28 states and the District of Columbia, and served 6.7 million beneficiaries; including more than 1.1 million people through Medicaid expansion programs in 16 states under the Patient Protection and Affordable Care Act (ACA).
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, 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 - 26 markets;
CHIP - 25 markets;
Aged, Blind and Disabled - 22 markets;
SNP - 20 markets;
Medicaid Expansion - 16 markets;
Long-Term Services and Supports - 14 markets;
MMP - 2 markets; and
other programs (e.g., administrative services, childless adults, developmentally disabled) - 9 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 and often addresses other social determinants that can impact people’s health status and health system usage.
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 expansions to 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.
UnitedHealthcare Global
UnitedHealthcare Global serves more than 4 million people with medical benefits and 2 million with dental benefits, residing principally in Brazil, but also in more than 130 other countries. UnitedHealthcare Global owns and operates nearly 150 hospitals, specialty centers, primary care and emergency services clinics in Brazil and Portugal. UnitedHealthcare Global provides a comprehensive range of health and mobilization capabilities and supports the health systems of individual nations with support for improving health care financing and delivery.

Optum
Optum is a health services business serving the broad health care marketplace, including:
Those who need care: the consumers who need the right support, information, resources and products to achieve their health goals.
Those who provide care: pharmacies, hospitals, physicians, practices and other health care facilities seeking to modernize the health system and support the best possible patient care and experiences.
Those who pay for care: employers, health plans, and state, federal and municipal agencies devoted to ensuring the populations they sponsor receive high-quality care, administered and delivered efficiently and effectively.
Those who innovate for care: global life sciences organizations dedicated to developing more effective approaches to care, enabling technologies and medicines that improve care delivery and health outcomes.
Optum operates three business segments leveraging distinctive capabilities in data and analytics, pharmacy care services, population health, health care delivery and health care operations:
OptumHealth focuses on care delivery, care management, wellness and consumer engagement, and health financial services;
OptumInsight specializes in data and analytics and other health care information technology services, and delivers operational services and support; and
OptumRx provides pharmacy care services.
OptumHealth
OptumHealth is a diversified health and wellness business serving the physical, emotional and health-related financial needs of 91 million unique individuals. OptumHealth enables population health management through programs offered by employers, payers, government entities and directly with the care delivery system. OptumHealth products and services deliver value by improving quality and patient satisfaction while lowering cost. 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.
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 more than 30,000 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 strategic partnerships, alliances and ownership arrangements OptumHealth helps care providers adopt new approaches and technologies that improve the coordination of care across all providers involved in patient care. MedExpress’ over 240 neighborhood care centers provide urgent and walk-in care services with a consumer-friendly approach and Surgical Care Affiliates’ 200 independent ambulatory surgical centers and surgical hospitals provide high-value surgical services at a lower cost than a traditional in-patient hospital setting.
OptumHealth’s mobile care delivery business delivers occupational health and medical services to government customers, with a particular focus on the U.S. military.
OptumHealth serves people through population health management services that meet both the preventive care and health intervention needs of consumers across the care continuum - physical health and wellness, mental health, complex medical conditions, disease management, hospitalization and post-acute care. This includes offering access to proprietary networks of provider specialists in many clinical specialties, including behavioral health, organ transplant, chiropractic and physical therapy. OptumHealth engages consumers in managing their health, including guidance, tools and programs that help them achieve their health goals and maintain healthy lifestyles.
Optum Financial Services, through Optum Bank, a wholly-owned subsidiary, serves consumers through 4.8 million health savings and other accounts with over $8 billion in assets under management as of December 31, 2017. During 2017, Optum Bank processed nearly $150 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.
OptumHealth offers its products on a risk basis, where it assumes responsibility for health care costs in exchange for a monthly premium per individual served, on an administrative fee basis, under which it manages or administers delivery of the products or services in exchange for a fixed monthly fee per individual served, or on a fee-for-service basis, where it delivers medical services to patients in exchange for a contracted fee. For its financial services offerings, OptumHealth charges fees and earns investment income on managed funds.

6


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).
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, advance quality, 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, 2017, was $15.0 billion, of which $8.3 billion is expected to be realized within the next 12 months. This includes $5.4 billion related to intersegment agreements, all of which are in the current portion of the backlog. OptumInsight’s aggregate backlog at December 31, 2016, was $12.6 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 more than 100,000 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.
OptumRx

GOVERNMENT REGULATION
Most of our 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) and risk adjustment 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 relating to the administration of contracts with federal agencies. In addition, our business is 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.
The Tax Cuts and Jobs Act. On December 22, 2017, the U.S. federal government enacted a tax bill (Tax Cuts and Jobs Act or Tax Reform). The Tax Cuts and Jobs Act changed existing United States tax law and includes numerous provisions that will affect our results of operations, financial position and cash flows. For instance, Tax Reform reduced the U.S. corporate income tax rate and changed business-related exclusions and deductions and credits.
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

8


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 administration of benefits, claims payment and member appeals under health care plans governed by ERISA.
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 adopted 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.
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 protected 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

9


laws requiring businesses to meet minimum cyber-security standards and 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. 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.
Pharmacy and PBM Regulations
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 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 those requiring us 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.
Legislation seeking to regulate PBM activities introduced or enacted in a number of states could impact our business practices. Additionally, organizations like the National Association of Insurance Commissioners periodically issue model regulations and credentialing organizations, like the National Committee for Quality Assurance (NCQA) and the Utilization Review Accreditation Commission (URAC), may establish standards that impact PBM, mail or specialty pharmacy activities. While these model regulations and standards do not have the force of law, they may influence states to adopt their recommendations and impact the services we deliver to our clients. There is both federal and state legislation affecting the ability to limit access to a pharmacy provider network or remove network providers. Additionally, many states limit our ability to manage and establish maximum allowable costs for generic prescription drugs. With respect to formulary services, a number of government entities, including CMS, HHS and state departments of insurance, regulate the administration of prescription drug benefits offered through federal or state exchanges. Many states also regulate the scope of prescription drug coverage, as well as the delivery channels to receive such prescriptions, for insurers, MCOs and Medicaid managed care plans. These regulations could limit or preclude (i) certain plan designs, (ii) limited networks, (iii) requirements to use particular care providers or distribution channel, (iv) copayment differentials among providers and (v) formulary tiering practices.
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 such as the Federal Tort Claims Act, the Federal Postal Service Act and the Federal Trade Commission‘s (FTC) Telemarketing Sales Rule. Most states also have similar consumer protection laws.
Certain laws, such as the Telephone Consumer Protection Act, give the FTC, Federal Communications Commission (“FCC”) and state attorneys general the ability to regulate, and bring enforcement actions relating to, telemarketing practices and certain automated outbound contacts such as phone calls, texts or emails. Under certain circumstances, these laws may provide consumers with a private right of action. Violations of these laws could result in substantial statutory penalties and other sanctions.
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

10


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, 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 care company, we operate in highly competitive markets. Our competitors include managed health care companies, insurance companies, HMOs, TPAs, PBMs 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.

ITEM 1A. 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 in this report 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

13


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 and Medicaid contracts are typically based on a fixed monthly rate per individual served for a 12-month period and is generally priced one to six months before the contract commences. Our revenue on Medicare policies is based on bids submitted to CMS in June the year before the contract year. Although we base the commercial and Medicaid 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 treatment guidelines, 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 2017 medical costs for commercial insured products were 1% higher, without proportionally higher revenues from such products, our annual net earnings for 2017 would have been reduced by approximately $235 million, excluding any offsetting impact from risk adjustment 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 government contracts 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 that 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; and 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 or provide our products and services, or to do so at targeted operating margins, or may increase the regulatory burdens under which we operate.
The laws and rules governing our businesses and interpretations of those laws and rules are subject to frequent change. For example, legislative, administrative and public policy changes to the ACA are being debated, and we cannot predict if the ACA will be further modified or repealed or replaced. Additionally, the integration into our businesses of entities that we acquire may affect the way in which existing 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 businesses could force us to change how we do business, restrict revenue and enrollment growth, increase our

14


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 also must 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 on many of our products to HHS for monitoring purposes. 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.
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 and CHIP, 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

15


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. If 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, 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 others, quality of care, preventive 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 the marketability of our plans, our membership levels, results of operations, financial position and cash flows. Any changes in standards or care delivery models that apply to government health care programs, including Medicare and Medicaid, 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 adjustment of 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. Certain of our local plans have been selected for such audits, which 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. For example, various governmental agencies have conducted investigations into certain PBM practices, which have resulted in other PBMs agreeing to civil penalties, including the payment of money and corporate integrity agreements. Additionally, 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 or erroneous 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 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 protected 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 protected 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 are regularly the target of attempted cyber-attacks and other security threats and may be subject to breaches of the information technology systems we use. We have programs in place to detect, contain and respond to data security incidents and provide employee awareness training around phishing, malware and other cyber risks to protect, to the greatest extent possible, against cyber risks and security breaches. However, because the techniques used to obtain unauthorized access, disable or degrade service, or sabotage systems change frequently and may be difficult to detect for long periods of time, we may be unable to anticipate these techniques or implement adequate preventive measures. Experienced computer programmers and hackers may be able to penetrate our layered security controls and misappropriate or compromise protected personal information or proprietary or confidential information or that of third-parties, create system disruptions or cause system 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. Hardware, software, or applications we develop or procure from third

16


parties may contain defects in design or manufacture or other problems that could unexpectedly compromise information security. 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 customer’s data.
The costs to eliminate or address the foregoing security threats and vulnerabilities before or after a cyber-incident could be material. 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, 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 fail to comply with applicable privacy, security and data laws, regulations and standards, including with respect to third-party service providers that utilize protected 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 protected 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 HIPAA imposed further restrictions on our ability to collect, disclose and use protected personal information and imposed additional compliance requirements on our business.
Internationally, many of the jurisdictions in which we operate have established their own data security and privacy legal framework with which we or our customers must comply. We expect that there will continue to be new proposed laws, regulations and industry standards concerning privacy, data protection and information security in the European Union and other jurisdictions, and we cannot yet determine the impacts such future laws, regulations and standards may have on our businesses or the businesses of our customers. For example, in May 2018, the European Union’s General Data Protection Regulation will overhaul data protection laws in the European Union. The new regulation will supersede current European Union data protection legislation, may impose more stringent European Union data protection requirements on us or our customers, and may prescribe greater penalties for noncompliance.
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 protected 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 protected 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 beneficiary inducement and other laws that govern the relationships of the business with pharmaceutical manufacturers, physicians, pharmacies, customers and consumers. As a provider of pharmacy benefit management services, OptumRx is also subject to an increasing number of licensure, registration and other laws and accreditation standards that impact the business practices of a pharmacy benefit manager. OptumRx also conducts business through home delivery, specialty pharmacies and home infusion, which subjects it to extensive federal, state and local laws and regulations, including

17


those of the DEA and individual state controlled substance authorities, the FDA and Boards of Pharmacy. 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 legislation and regulations regarding the receipt or disclosure of rebates and other fees from pharmaceutical companies, the development and use of formularies and other utilization management tools, the use of average wholesale prices or other pricing benchmarks, pricing for specialty pharmaceuticals, limited access to networks and pharmacy network reimbursement methodologies.
We could face potential claims in connection with purported errors by our home delivery or specialty pharmacies or the provision of home infusion services, including in connection with the risks inherent in the packaging and distribution of pharmaceuticals and other health care products. Disruptions from any of our home delivery, specialty pharmacy or home infusion services 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 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. If 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, South America 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. Our competitive position may also 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 health 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. In addition, 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 and health care usage, and we may face challenges from 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 by us 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, divert management’s attention from our operations 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 do business with us and may change the competitive landscape. Such organizations or groups of physicians may compete directly with us, which could adversely affect our 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

18


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 which 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 some of our businesses, including OptumHealth and UnitedHealthcare Brazil, depend on maintaining satisfactory physician relationships as employees, independent contractors or joint venture partners. 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 businesses could suffer if our affiliated physician organizations fail to maintain relationships with these health insurance or HMO companies, or fail to 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. Physicians also provide medical services at facilities owned by 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 (including claims related to the delivery of health care services, such as medical malpractice by staff at our affiliates’ facilities, or 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. While 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

19


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 domestically or outside the United States 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 on 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, languages, 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 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 shareholders’ 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 nonexclusive producers and consultants for whose services and allegiance we must compete intensely. Our sales would be materially and adversely affected if we are 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 commission levels.
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, such actions 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 also have 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.

20


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.
Our investment portfolio may suffer losses, which could 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, 2017. 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 issuers of our investments in corporate and municipal bonds), could reduce our investment income and require us to write down the value of our investments, which could 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 an 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, 2017, goodwill and other intangible assets had a carrying value of $63 billion, representing 45% 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

21


consequences. Our process of 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 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 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 on 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 on the volume of premium revenues generated by the applicable subsidiary. In most states, we are required to seek 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. Any downgrades in our credit ratings could materially increase our costs of or ability to access funds in the debt capital markets and otherwise materially increase our operating costs.

DIVIDEND POLICY
In June 2017, our Board of Directors increased the Company’s quarterly cash dividend to shareholders to an annual dividend rate of $3.00 per share compared to the annual dividend rate of $2.50 per share, which the Company had paid since June 2016. 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 2017, we repurchased 1.6 million shares at an average price of $210.97 per share. As of December 31, 2017, we had Board authorization to purchase up to 42 million shares of our common stock.

PERFORMANCE GRAPH
The following performance 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, 2017. We are not included in the Fortune 50 Group index. In calculating the cumulative total shareholder return of the indexes, the shareholder returns of the Fortune 50 Group companies 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, 2012 in our common stock and in each index, and that dividends were reinvested when paid.
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.

ITEM 7.
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 care company dedicated to helping people live healthier lives and helping make the

25


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 delivery, 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.
Business Trends
Our businesses participate in the United States, South America 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.
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, including minimum MLR thresholds. 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 imposed a one year moratorium for 2017 on the collection of the Health Insurance Industry Tax. Pricing for contracts that cover a portion of calendar year 2018 reflected the impact of the returning Health Insurance Industry Tax. Conversely, 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 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 by engaging physicians and consumers with information and helping them make clinically sound choices, with the objective of helping them achieve high quality, affordable care.
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, 2017, we served nearly 16 million people through some form of aligned contractual arrangement, including full-risk, shared-

26


risk and bundled episode-of-care and performance incentive payment approaches. As of December 31, 2017, our contracts with value-based elements total nearly $65 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.”
Medicare Advantage Rates. Final 2018 Medicare Advantage rates resulted in an increase in industry base rates of approximately 0.45%, well short of the industry forward medical cost trend of 3%, as well as the return of the Health Insurance Industry Tax in 2018, described below, 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, and adjust members' benefits, implement or increase the member premiums that supplement the monthly payments we receive from the government. Additionally, we decide annually 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.
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 2017 payment year, approximately 80% of our Medicare Advantage members were in plans rated four stars or higher. We expect that at least 85% of our Medicare Advantage members will be in plans rated four stars or higher for payment year 2018. 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.
Tax Reform. Tax Reform was enacted by the U.S federal government in December 2017, changing existing United States tax law including reducing the U.S. corporate income tax rate. The Company re-measured deferred taxes as of the date of enactment, which resulted in a $1.2 billion reduction to the net deferred tax liability and corresponding increase to earnings in 2017. With Tax Reform, we expect that our effective tax rate in 2018 will be approximately 24%.
Health Insurance Industry Tax. A provision in the 2016 Federal Budget imposed a one year moratorium for 2017 on the collection of the Health Insurance Industry Tax. In 2018, the industry-wide amount of the Health Insurance Industry Tax will be $14.3 billion and we expect our portion to be approximately $2.8 billion. A one year moratorium on the collection of the Health Insurance Industry Tax will occur in 2019.

2017 RESULTS OF OPERATIONS COMPARED TO 2016 RESULTS.
Consolidated Financial Results
Revenue
The increase in revenue was primarily driven by organic growth in the number of individuals served across our UnitedHealthcare benefits businesses and growth across the Optum business. The increase was partially offset by revenue decreases due to the withdrawals of the ACA-compliant products in the individual market and the effects of the Health Insurance Industry Tax moratorium.
Medical Costs and MCR
Medical costs increased due to risk-based membership growth and medical cost trends. The MCR increased due to the effects of the Health Insurance Industry Tax moratorium, offset primarily by the reduction in individual ACA business, medical management initiatives and an increase in favorable medical cost reserve development.
Income Tax Rate
Our effective tax rate decreased primarily due to the impact of Tax Reform and the Health Insurance Tax moratorium. The provision for income taxes included the $1.2 billion benefit from the revaluation of net deferred tax liabilities.

In the commercial group market, broad-based growth was across group sizes and regions, led by gains in services to small groups and resulted in the overall increase in people served through risk-based benefit plans. Fee-based commercial group business declined due to the non-renewal of one public sector customer. Membership in individual business decreased due to our reduced participation in ACA-compliant products in 2017. 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, which were partially offset by the reduction of people served in ACA-compliant individual products and the impact of the Health Insurance Industry Tax moratorium.
The increase in UnitedHealthcare’s earnings from operations was led by diversified growth and increased operating margin. The 2016 results included losses in ACA-complaint individual products and guaranty fund assessments.
Optum
Total revenues and earnings from operations 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 and earnings from operations increased at OptumHealth primarily due to organic and acquisition-related growth in care delivery.

30


OptumInsight
Revenue and earnings from operations at OptumInsight increased primarily due to growth in revenue management services and business process services.
OptumRx
Revenue and earnings from operations at OptumRx increased primarily due to client and consumer growth. In 2017, OptumRx fulfilled 1.3 billion adjusted scripts compared to 1.2 billion in 2016.
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 “Compensation-Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting,” which we adopted in the first quarter of 2016.
Reportable Segments
UnitedHealthcare
UnitedHealthcare’s revenue growth was due to growth in the number of individuals served across its businesses and price increases for underlying medical cost trends.
UnitedHealthcare’s operating earnings increased due to diversified growth, offset by guaranty fund assessments recorded in the fourth quarter of 2016.
Optum
Total revenues and operating earnings increased 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 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 1.2 billion adjusted scripts compared to 932 million in 2015.

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 2017, our U.S. regulated subsidiaries paid their parent companies dividends of $3.7 billion. For the year ended December 31, 2016, our U.S. regulated subsidiaries paid their parent companies dividends of $3.9 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 significant 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.

2017 Cash Flows Compared to 2016 Cash Flows
Increased cash flows provided by operating activities were primarily driven by higher net earnings and changes in working capital accounts, partially offset by the change in net deferred tax liabilities driven by tax reform.
Other significant changes in sources or uses of cash year-over-year included net repayments of debt compared to 2016 net proceeds from debt issuances, which were partially offset by lower net purchases of investments.
2016 Cash Flows Compared to 2015 Cash Flows
Cash flows provided by operating activities increased slightly as higher net earnings were mostly offset by increased CMS receivables and other operating items.
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.
Financial Condition
As of December 31, 2017, our cash, cash equivalent and available-for-sale investment balances of $42.4 billion included $12.0 billion of cash and cash equivalents (of which approximately $800 million was available for general corporate use), $28.4 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; 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 3.2 years and a weighted-average credit rating of “Double A” as of December 31, 2017. 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, 2017, our debt to debt-plus-shareholders’ equity ratio, as defined and calculated under the credit facilities, was approximately 37%.
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. For more information on our debt, 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, 2017 were as follows:

In January 2018, S&P Global affirmed our ratings and changed our outlook to Stable.
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

33


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.
Share Repurchase Program. As of December 31, 2017, we had Board authorization to purchase up to 42 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 2017, our Board increased our quarterly cash dividend to shareholders by 20% to an annual dividend rate of $3.00 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.”

(a)
Includes interest coupon payments and maturities at par or put values. 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.
(b)
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, 2017.
(c)
Includes obligations associated with contingent consideration and other payments related to business acquisitions, certain employee benefit programs, amounts accrued for guaranty fund assessments, unrecognized tax benefits, and various other long-term liabilities. Due to uncertainty regarding payment timing, obligations for employee benefit programs, charitable contributions, future settlements and other liabilities have been classified as “Thereafter.”
(d)
Includes commitments for redeemable shares of our subsidiaries. When the timing of the redemption is indeterminable, the commitment has been classified as “Thereafter.”
Pending Acquisitions. In December 2017, we entered into agreements to acquire two companies in the health care sector for a total of approximately $7.7 billion, which are not reflected in the table above. One of the acquisitions closed in January 2018; the other is expected to close later in 2018, subject to regulatory approval and other customary closing conditions.
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, 2017, 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.
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

34


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, 2017, our days outstanding in medical payables was 50 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 2017, 2016 and 2015 included favorable medical cost development related to prior years of $690 million, $220 million and $320 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 reserve estimates 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, 2017:

Medical Cost Per Member Per Month Trend Factors. 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 a review of a broad set of health care utilization indicators, including but not limited to, pharmacy utilization trends, inpatient hospital authorization data and influenza 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, 2017:

The completion factors and medical costs PMPM trend factors analyses above include outcomes that are considered reasonably likely based on our historical experience estimating liabilities for incurred but not reported benefit claims.
Management believes the amount of medical costs payable is reasonable and adequate to cover our liability for unpaid claims as of December 31, 2017; however, actual claim payments may differ from established estimates as discussed above. Assuming a hypothetical 1% difference between our December 31, 2017 estimates of medical costs payable and actual medical costs payable, excluding AARP Medicare Supplement Insurance and any potential offsetting impact from premium rebates, 2017 net earnings would have increased or decreased by $110 million.
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 Statements.” Risk adjustment data for 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.
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 analyses. 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

36


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: customer and/or 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, 2017. All of our reporting units had fair values substantially in excess of their carrying values.
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 2017.
LEGAL MATTERS
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, 2017, there were no significant concentrations of credit risk.
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, 2017, we had $15 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, 2017, $8.5 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.

37


The fair value of certain of our fixed-rate investments and debt also varies with market interest rates. As of December 31, 2017, $25.9 billion of our investments were fixed-rate debt securities and $28.7 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, 2017 and 2016 on our investment income and interest expense per annum and the fair value of our investments and debt (in millions, except percentages):

(a)
Given the low absolute level of short-term market rates on our floating-rate assets and liabilities as of December 31, 2017 and 2016, the assumed hypothetical change in interest rates does not reflect the full 100 and 200 basis point reduction, respectively, in interest income or interest expense, in 2017 and 2016, respectively, as the rate cannot fall below zero.
(b)
As of December 31, 2017 and 2016, 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 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, 2017, 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 $500 million and $1.1 billion, respectively. We manage exposure to foreign currency earnings risk primarily by conducting our international business operations in their functional currencies.
As of December 31, 2017, 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; and dividend paying stocks. Valuations in non-U.S. dollar funds are subject to foreign exchange rates.
