Item 1. Business

OVERVIEW

We are a leading multi-national healthcare enterprise that is committed to helping people live healthier lives. We take a local approach - with local brands and local teams - to provide fully integrated, high-quality, and cost-effective services to government-sponsored and commercial healthcare programs, focusing on under-insured and uninsured individuals. We also provide education and outreach programs to inform and assist members in accessing quality, appropriate healthcare services. We believe our local approach, including member and provider services, enables us to provide accessible, quality, culturally-sensitive healthcare coverage to our communities. Our population health management, educational and other initiatives are designed to help members best utilize the healthcare system to ensure they receive appropriate, medically necessary services and effective management of routine, severe and chronic health problems, resulting in better health outcomes. We combine our decentralized local approach for care with a centralized infrastructure of support functions such as finance, information systems and claims processing.

Our initial health plan commenced operations in Wisconsin in 1984. We were organized in Wisconsin in 1993 as a holding company for our initial health plan and reincorporated in Delaware in 2001. Our stock is publicly traded on the New York Stock Exchange under the ticker symbol "CNC."

We operate in two segments: Managed Care and Specialty Services. Our Managed Care segment provides health plan coverage to individuals through government subsidized and commercial programs. Our Specialty Services segment includes companies offering diversified healthcare services and products to our Managed Care segment and other external customers. For the year ended December 31, 2019, our Managed Care and Specialty Services segments accounted for 95% and 5%, respectively, of our total external revenues. Our membership totaled 15.2 million as of December 31, 2019. For the year ended December 31, 2019, our total revenues and net earnings attributable to Centene were $74.6 billion and $1.3 billion, respectively, and our total cash flow from operations was $1.5 billion.

WellCare Acquisition

On January 23, 2020, we acquired all of the issued and outstanding shares of WellCare Health Plans, Inc. (WellCare, and such acquisition, the WellCare Acquisition). The transaction is valued at approximately $19.6 billion, including the assumption of $1.95 billion of outstanding debt. The cash portion of the acquisition was funded through the issuance of long-term debt in December 2019. The WellCare Acquisition brings a high-quality Medicare platform and further extends our robust Medicaid offerings. The WellCare Acquisition also enables us to provide access to more comprehensive and differentiated solutions across more markets with a continued focus on affordable, high-quality, culturally-sensitive healthcare services. With the WellCare Acquisition, we further broadened our product offerings by adding a Medicare prescription drug plan to our existing business lines. The business discussion reflects only Centene operations in 2019, prior to the completion of the WellCare Acquisition, unless specifically noted.

INDUSTRY

We provide a full spectrum of managed healthcare products and services, primarily through Medicaid, commercial and Medicare products. We currently have operations domestically and internationally.

Medicaid

Established in 1965, Medicaid is the largest publicly funded program in the United States, and provides health insurance to low-income families and individuals with disabilities. Authorized by Title XIX of the Social Security Act, Medicaid is an entitlement program funded jointly by the federal and state governments and administered by the states. The majority of funding is provided at the federal level. Each state establishes its own eligibility standards, benefit packages, payment rates and program administration within federal standards. As a result, there are 56 Medicaid programs - one for each U.S. state, each U.S. territory and the District of Columbia. Eligibility is based on a combination of household income and assets, often determined by an income level relative to the federal poverty level. Historically, children have represented the largest eligibility group. Many states have selected Medicaid managed care as a means of delivering quality healthcare and controlling costs. We refer to these states as mandatory managed care states.

Under the Affordable Care Act (ACA), Medicaid coverage was expanded to all individuals under age 65 with incomes up to 138% of the federal poverty level beginning January 1, 2014, subject to the states' elections. The federal government paid the entire costs for Medicaid Expansion coverage for newly eligible beneficiaries from 2014 through 2016, 95% of the costs in 2017, 94% of the costs in 2018, 93% of the costs in 2019, and 90% of the costs in 2020. Assuming that the current program remains in effect unchanged, in subsequent years the federal share is scheduled to remain at 90%.

Established in 1972 and authorized by Title XVI of the Social Security Act, Aged, Blind, or Disabled, or collectively ABD, covers low-income persons with chronic physical disabilities or behavioral health impairments. ABD beneficiaries represent a growing portion of all Medicaid recipients. In addition, ABD recipients typically utilize more services as a result of their health status.

The Balanced Budget Act of 1997 created the State Children's Health Insurance Program (CHIP) to help states expand coverage primarily to children whose families earned too much to qualify for Medicaid, yet not enough to afford private health insurance. Costs related to the largest eligibility group, children, are primarily composed of pediatrics and family care. These costs tend to be more predictable than those associated with other healthcare issues which predominantly affect the adult population.

Long-Term Services and Supports (LTSS) is a Medicaid product that covers Institutional/Residential Care (Nursing Facilities, Intermediate Care Facilities) and Home and Community Based Services (HCBS) for beneficiaries requiring assistance with their activities of daily living, such as bathing, dressing and transferring. The most common HCBS services include personal care, adult day care, non-emergent transportation, home-delivered meals and personal emergency response systems. LTSS services are provided for individuals requiring nursing home level of care, receiving waiver services, or entitled to state Medicaid LTSS benefits. The largest groups receiving LTSS, by spending, are older individuals and individuals with physical disabilities, followed by individuals with intellectual and developmental disabilities, those with serious mental illness and/or serious emotional disturbance and other populations. States are increasingly turning to managed care as a solution to provide coordinated, holistic care to their LTSS beneficiaries. According to the National Association of States United for Aging and Disabilities, 24 states utilize some form of managed LTSS, up from eight in 2004.

The majority of youth and children in foster care qualify for Medicaid, most commonly through Title IV-E of the Social Security Act, which provides funding to support safe and stable out-of-home care for children who are removed from their homes. The federal government has enacted legislation establishing guidelines and requirements for state child welfare agencies related to the health and well-being of children in foster care, including the provision of grants and technical assistance to enable states to meet these needs and make explicit connections with state Medicaid. In addition, the ACA requires states to make former foster care children eligible for Medicaid until they reach the age of 26, provided that they turned 18 while in foster care, and were enrolled in Medicaid at that time.

CMS estimated the total Medicaid market to be approximately $595 billion in 2018, and estimated the market will grow to $1.0 trillion by 2027. Medicaid spending is estimated to have increased by 2.2% in 2018 and is projected to increase at an average annual rate of 5.5% between 2018 and 2027.

While Medicaid programs have directed funds to many individuals who cannot afford or otherwise maintain health insurance coverage, they did not initially address the inefficient and costly manner in which the Medicaid population tends to access healthcare. Medicaid recipients in non-managed care programs typically have not sought preventive care or routine treatment for chronic conditions, such as asthma and diabetes. Rather, they have sought healthcare in hospital emergency departments, which is typically more expensive. As a result, many states without managed care programs have found that the costs of providing Medicaid benefits have increased while the medical outcomes for the recipients remained unsatisfactory.

We believe managed care has improved the quality of care for Medicaid beneficiaries and lowered costs. The majority of states have mandated that their Medicaid recipients enroll in managed care plans. Other states are considering moving to a mandated managed care approach for additional populations and products. As a result, we believe a significant market opportunity exists for managed care organizations with operations and programs focused on the distinct socio-economic, cultural and healthcare needs of the uninsured population and the Medicaid populations.

Commercial

Established in 2010 and operational in 2014, the ACA created Health Insurance Marketplaces, which are a key component of the ACA and provide an opportunity for individuals and small businesses to obtain health insurance. States have the option of operating their own Marketplace or partnering with the federal government. States choosing neither option currently default to a federally-facilitated Marketplace. Premium subsidies are available to make coverage more affordable and access to Marketplaces is limited to U.S. citizens and legal immigrants. Insurers are required to offer a minimum level of benefits with coverage that varies based on premiums and out-of-pocket costs. Premium subsidies are provided to families without access to other coverage and with incomes generally between 100-400% of the federal poverty level, with some exceptions, to help them purchase insurance through the Marketplaces. These subsidies are offered on a sliding scale basis.

We also offer commercial healthcare products to individuals through large and small employer groups. We offer plans with differing benefit designs and varying levels of co-payments at different premium rates. These plans are offered generally through contracts with participating network physicians, hospitals and other providers. Coverage typically is subject to deductibles and copayments or coinsurance.

Medicare

We contract with CMS under the Medicare Advantage program to provide Medicare Advantage products directly to Medicare beneficiaries as well as through employer and union groups. The Medicare program provides health care coverage primarily to individuals age 65 or older as well as to individuals with certain disabilities.

We provide or arrange healthcare benefits for services normally covered by Medicare, plus a broad range of healthcare benefits for services not covered by traditional Medicare, usually in exchange for a fixed monthly premium per member from CMS that varies based upon the county in which the member resides, demographic factors of the member such as age, gender and institutionalized status, and the health status of the member. Any benefits that are not covered by Medicare may result in an additional monthly premium charged to the enrollee or through portions of payments received from CMS that may be allocated to these benefits, according to CMS regulations and guidance. Many of our Medicare Advantage members pay no monthly premium to us for these additional benefits.

We provide a wide range of Medicare products, including Medicare Advantage plans with and without prescription drug coverage and Medicare supplement products that supplement traditional fee-for-service Medicare coverage. Our subsidiaries have a number of contracts with CMS under the Medicare Advantage program authorized under Title XVIII of the Social Security Act.

A portion of Medicare beneficiaries are dual-eligible, low-income seniors and people with disabilities who are enrolled in both Medicaid and Medicare. According to CMS, there were approximately 10.9 million dual-eligible enrollees in 2018. These dual-eligible members may receive assistance from Medicaid for benefits, such as nursing home care, HCBS, and/or assistance with Medicare premiums and cost sharing. Dual-eligibles also use more services due to their tendency to have more chronic health issues. We serve dual-eligibles through our Aged, Blind and Disabled (ABD), Long Term Services and Supports (LTSS), Medicare-Medicaid Plans (MMP) and Medicare Advantage Dual Special Needs Plan (DSNP) lines of business.

CMS developed the Medicare Advantage Star ratings system to help consumers choose among competing plans, awarding between 1.0 and 5.0 stars to Medicare Advantage plans based on performance in certain measures of quality. The Star ratings are used by CMS to award quality bonus payments to Medicare Advantage plans. Beginning with the 2014 Star ratings (calculated in 2013), Medicare Advantage plans are required to achieve a minimum of 4.0 Stars to qualify for a quality bonus payment. The methodology and measures included in the Star ratings system can be modified by CMS annually and Star ratings thresholds are based on performance of Medicare Advantage plans nationally.

CMS estimated the total Medicare market was approximately $747 billion in 2018, and estimated the market will grow to approximately $1.4 trillion by 2027. Medicare spending is estimated to have increased 5.9% in fiscal 2018 and is projected to increase at an average annual rate of 7.4% between 2018 and 2027.

International

We currently have a growing international presence in Spain, the United Kingdom (UK) and Slovakia. In June 2019, we purchased an additional 40% ownership in Ribera Salud for $54 million, bringing our total ownership to 90%. Ribera Salud manages health administration concessions in various regions in Spain. In the UK, our subsidiary, Operose Health (Group) Limited (Operose Health), is one of the largest provider networks and delivers medical and community based services in the primary care sector of the National Health Service (NHS), which is the publicly funded, national healthcare system for England. We also have additional noncontrolling investments in the UK. Our equity method investee in Slovakia provides radiology services in the region.

OUR COMPETITIVE STRENGTHS

Our approach is based on the following key competitive strengths:

•

Expertise in Government Sponsored Programs. For more than 35 years, we have developed a specialized services expertise that has helped us establish and maintain relationships with members, providers and our government customers. We have implemented programs developed to achieve savings for our government customers and improve health outcomes and quality of care for members. We work to assist the states in which we operate in addressing the operating challenges they face.

•

Quality and Innovation. Our innovative population health management programs focus on improving quality of care in areas that have the greatest impact on our members. We concentrate on serving the whole person to impact outcomes and costs. We recognize the importance of member-focused delivery of quality managed care services and have developed award winning education and outreach programs including the My Health Pays program, On.Demand Diabetes, Start Smart For Your Baby, and MemberConnections. It is our objective to provide access to the highest quality of care for our members. As a validation of that objective, we pursue accreditation by independent organizations that have been established to promote healthcare quality. We seek the National Committee for Quality Assurance (NCQA) and the Utilization Review Accreditation Commission (URAC) Health Plan Accreditation in eligible states.

•

Innovative Technology and Scalable Systems. The ability to access data and translate it into meaningful information is essential to operating across a multi-state service area in a cost-effective manner. Our centralized information systems support our core processing functions under a set of integrated databases and are designed to be both replicable and scalable to accommodate organic growth and growth from acquisitions. We continue to enhance our systems in order to leverage the platforms we have developed for our existing states for configuration into new states or health plan acquisitions. We believe our predictive modeling technology enables our population health management operations to proactively case and disease manage specific high risk members. It can recommend medical care opportunities using a mix of company defined algorithms and evidence based medical guidelines. Interventions are determined by the clinical indicators, the ability to improve health outcomes, and the risk profile of members. We believe our integrated approach helps to assure that consistent sources of claim and member information are provided across all of our health plans. Our membership and claims processing system is capable of expanding to support additional members in an efficient manner.

•

Financial Strength and Scale. We are a large healthcare enterprise with approximately $75 billion in revenue and $1.5 billion in operating cash flow in 2019. Our strong historical operating performance, size, and scale allow us to continue to grow, diversify and invest in our businesses through strategic acquisitions and investments in technology and other resources that support our business, allowing us to navigate the changing healthcare landscape. We are a leader in the four largest Medicaid states. We seek to continue to increase our Medicaid, Medicare and Health Insurance Marketplace membership through alliances with key providers, outreach efforts, development and implementation of community-specific products and acquisitions. In 2020, we expanded our Health Insurance Marketplace footprints in several existing markets, and we completed the WellCare Acquisition, further expanding our scale and presence. In addition, a nationally recognized statistical rating organization recently raised our long-term issuer credit rating to an investment grade rating.

•

Diversified Business Lines. We continue to broaden our service offerings to address areas that we believe have been traditionally under-served by Medicaid and Medicare managed care organizations. In addition to our Medicaid, Medicare, and Medicaid-related managed care services, our service offerings include behavioral health management, care management software, correctional healthcare services, dental benefits management, commercial programs, primary care services, life and health management, vision benefits management, pharmacy benefits management, specialty pharmacy, telehealth services and government-sponsored care under its federal contracts with the Department of Defense (DoD). Through the utilization of a multi-business line approach, we are able to improve the quality of care, improve outcomes, diversify our revenues and help control our medical costs. In 2019, we served managed care members in 30 states through approximately 350 product solutions. We are constantly evaluating new opportunities for expansion both domestically and abroad.

•

Localized Approach with Centralized Support Infrastructure. We take a localized approach to managing our subsidiaries, including provider and member services. This approach enables us to facilitate access by our members to high quality, culturally sensitive healthcare services. Our systems and procedures have been designed to address these community-specific challenges through outreach, education, transportation and other member support activities. For example, our community outreach programs work with our members and their communities to promote health and self-improvement through education on how best to access care. We complement this localized approach with a centralized infrastructure of support functions such as finance, information systems and claims processing, which allows us to minimize selling, general and administrative (SG&A) expenses and to integrate and realize synergies from acquisitions. We believe this combined approach allows us to efficiently integrate new business opportunities in both Managed Care and Specialty Services, while maintaining our local accountability and improved access.

MANAGED CARE

Benefits to Customers

We feel that our ability to establish and maintain a leadership position in the markets we serve results primarily from our demonstrated success in providing quality care while reducing and managing costs, and from our specialized programs with state governments. Among the benefits we are able to provide to the states with which we contract are:

•

Significant cost savings and budget predictability compared to state paid reimbursement for services. We bring experience relating to quality of care improvement methods, utilization management procedures, an efficient claims payment system, and provider performance reporting, as well as managers and staff experienced in using these key elements to improve the quality of and access to care. We generally receive a contracted premium on a per member basis and are responsible for the medical costs and, as a result, provide budget predictability.

•

Data-driven approaches to balance cost and verify eligibility. We seek to ensure effective outreach procedures for new members, then educate them and ensure they receive needed services as quickly as possible. Our IT department has created mapping/translation programs for loading membership and linking membership eligibility status to all of Centene's subsystems. We utilize predictive modeling technology to proactively case and disease manage specific high risk members. In addition, we have developed Centelligence, our enterprise data warehouse system to provide a seamless flow of data across our organization, enabling providers and case managers to access information, apply analytical insight and make informed decisions.

•	Establishment of realistic and meaningful expectations for quality deliverables. We have collaborated with state agencies in redefining benefits, eligibility requirements and provider fee schedules with the goal of maximizing the number of individuals covered through Medicaid.

•

Managed care expertise in government subsidized programs. Our expertise in Medicaid has helped us establish and maintain strong relationships with our constituent communities of members, providers and state governments. We provide access to services through local providers and staff that focus on the cultural norms of their individual communities. To that end, systems and procedures have been designed to address community-specific challenges through outreach, education, transportation and other member support activities.

•	Improved quality and medical outcomes. We have implemented programs to enhance the ability of providers to improve the quality of healthcare delivered to our members. This is demonstrated through health plan accreditations and program awards.

•	Timely payment of provider claims. We are committed to ensuring that our information systems and claims payment systems meet or exceed state requirements. We continuously endeavor to update our systems and processes to improve the timeliness of our provider payments.

•

Provider outreach and programs. Our health plans have adopted a physician-driven approach where network providers are actively engaged in developing and implementing healthcare delivery policies and strategies. We prepare provider comparisons on a severity adjusted basis. This approach is designed to eliminate unnecessary costs, improve services to members and simplify the administrative burdens placed on providers.

•

Care management for complex populations. Through our experience with Medicaid populations and long-time presence in states with experience in long-term care for children and adolescents in the foster care system, we have developed care management, service coordination and crisis prevention/response programs that increase opportunities for successful outcomes for members. This experience has led to partnerships with specialized networks and community advocates as states transition to managed care programs for vulnerable and complex populations.

•

Responsible collection and dissemination of utilization data. We gather utilization data from multiple sources, allowing for an integrated view of our members' utilization of services. These sources include medical, vision and behavioral health claims and encounter data, pharmacy data, dental vendor claims and authorization data from the authorization and case management system utilized by us to coordinate care.

•	Timely and accurate reporting. Our information systems have reporting capabilities which have been instrumental in identifying the need for new and/or improved healthcare and specialty programs. For state agencies, our reporting capability is important in demonstrating an auditable program.

•	Fraud, waste and abuse prevention. We have several systems in place to help identify, detect and investigate potential fraud, waste, and abuse, including pre and post payment review software. We collaborate with state and federal agencies and assist with investigation requests. We use nationally recognized standards to benchmark our processes.

Member Programs and Services

We recognize the importance of member-focused delivery of quality managed care services. Our locally-based staff assists members in accessing care, coordinating referrals to related health and social services and addressing member concerns and questions. While covered healthcare benefits vary from customer to customer and program to program, our health plans generally provide the following services:

•	primary and specialty physician care;

•	inpatient and outpatient hospital care;

•	emergency and urgent care;

•	prenatal care;

Many of these programs have been recognized with awards for their excellence in education, outreach and/or case management techniques. These awards include Case In Point, Hermes Awards, U.S. Environmental Protection Agency and National Health Information Awards.

•

Start Smart For Your Baby, or Start Smart, is our award winning prenatal and infant health program designed to increase the percentage of pregnant women receiving early prenatal care, reduce the incidence of low-birth-weight and pre-term babies, identify high-risk pregnancies, increase participation in the federal Women, Infant and Children program, prevent hospital admissions in the first year of life and increase well-child visits.

•

Readmission Reduction aims to reduce preventable readmissions by ensuring optimal transitional care from acute and non-acute settings. The program focuses on post-hospitalization outreach (PHO), calls to members to verify they understand their discharge instructions, follow up with a Primary Care Physician (PCP), receive medication reconciliation, and, for the highest-risk members, are linked with a Community Health Worker.

•

Chronic Conditions aims to improve the health and quality of life for members with diabetes, asthma, chronic obstructive pulmonary disease (COPD), congestive heart failure (CHF), coronary artery disease (CAD), and/or hypertension. The program focuses on reducing emergent utilization and inpatient admissions by increasing treatment adherence, removing barriers to care, and enhancing self-management skills.

•	Fall Prevention seeks to decrease the number and severity of older adult falls. The program also aims to support members in maintaining their safety, stability, and independence as long as possible. The program leverages an evidence-based falls prevention toolkit to identify members at risk of falling and provide education and interventions to reduce fall risk.

•

Compassionate Connections (Palliative Care) works to identify members with at least one serious illness and provide necessary services to both members and those individuals close to them. Potential services may include detailed advanced care planning, a multi-team home visit and home health services, and additional social support. Providing palliative care services works to help alleviate members' suffering, and in turn, provide a better quality of life.

•	ER Diversion strives to identify members' reasons for visiting the ER and educate them on optimal locations for care in the future. The program also identifies opportunities for members to better manage their chronic conditions with the help of Primary Care Physicians (PCP) and Care Managers.

•

Fluvention works to decrease the spread of the flu by increasing the number of its managed care members that receive an annual flu vaccination. The campaign is designed to promote vaccinations as the key to flu prevention. Centene works to address these issues by utilizing enterprise-wide member and provider marketing and education, as well as increasing access to facilities that provide flu vaccinations.

•	Connections Plus is a cell phone program developed for high-risk members who have limited or no safe and reliable access to telephone. This program seeks to eliminate lack of safe, reliable access to a telephone as a barrier to coordinating care, thus reducing avoidable adverse events such as inappropriate emergency department utilization, hospital admissions and premature birth.

•	MemberConnections is a community face-to-face outreach and education program designed to create a link between the member and the provider and help identify potential challenges or risk elements to a member's health, such as nutritional challenges and health education shortcomings.

•

The ScriptAssist for Hepatitis C Adherence Program seeks to empower patients towards Hepatitis C virus treatment success through a series of telephonic interventions. Goals of the program include preventing premature treatment discontinuation due to medication side effects and access to therapy. Through its family of companies, Envolve clinicians and AcariaHealth patient care coordinators collaborate throughout a patient's treatment course to ensure appropriate therapy management and regimen access.

•	Health Initiatives for Children is aimed at educating child members on a variety of health topics. In order to empower and educate children, we have partnered with a nationally recognized children's author to develop our own children's book series on topics such as obesity prevention and healthy eating, asthma, diabetes, foster care, the ills of smoking, anti-bullying and heart health.

•	OpiEnd Youth Challenge is a targeted curriculum for adolescents ages 9 through 14 to raise awareness about opioid misuse and prevention. As part of the challenge, teachers and students discuss significant attributes of addiction and opioid misuse, and students then show their understanding by developing and submitting campaign messaging that depicts ways to prevent misuse.

•	Health Initiatives for Teens is aimed at empowering, educating and reinforcing life skills with our teenage members. We have developed an educational series that addresses health issues, dealing with chronic diseases including diabetes and asthma, as well as teen pregnancy.

•	Living Well with Sickle Cell is our innovative program that assists with coordination of care for our sickle cell members. Our program ensures that sickle cell members have established a medical home and work on strategies to reduce unnecessary emergency department visits through proper treatment to control symptoms and chronic complications, as well as promote self-management.

•	My Route for Health is our adult educational series used with our case management and disease management programs. The topics of this series include how to manage asthma, Chronic Obstructive Pulmonary Disease (COPD), diabetes, heart disease and HIV.

•	On.Demand Diabetes is a diabetes management support product designed to eliminate diabetic supply waste while increasing compliance and improving health outcomes for members with diabetes.

•

Community Health Record, our patient-centric electronic database, collects patient demographic data, clinician visit records, dispensed medications, vital sign history, lab results, allergy charts, and immunization data. Providers can directly input additional or updated patient data and documentation into the database. All information is accessible anywhere, anytime to all authorized users, including health plan staff, greatly facilitating coordinated care among providers.

•	My Health Pays offers members financial incentives for performing certain healthy behaviors. The incentives are delivered through a restricted-use prepaid debit card. This incentive-based approach effectively increases the utilization of preventive services while strengthening the relationships between members and their primary care providers.

•

The Asthma Management Program integrates a hands-on approach with a flexible outreach methodology that can be customized to suit different age groups and populations affected by asthma. We provide proactive identification of members, stratification into appropriate levels of intervention including home visits, culturally sensitive education, and robust outcome reporting. The program also includes aggressive care coordination to ensure patients have basic services such as transportation to the doctor, electricity to power the nebulizer, and a clean, safe home environment.

•	Preventive Care Programs are designed to educate our members on the benefits of Early and Periodic Screening, Diagnosis and Treatment (EPSDT) services. We have a systematic program of communicating, tracking, outreach, reporting and follow-through that promotes state EPSDT programs.

•	Readmission Reduction Program utilizes a proprietary scoring methodology to evaluate members' risks on preventable readmissions. Members with higher risk scores are identified at the point of admission to an acute care setting, then concurrently managed during the in-patient stay, and followed up with post discharge outreach to provide effective transition of care.

•	Outcomes Improvement Central (OIC) is a highly collaborative initiative that empowers partners across the organization to develop evidence-based clinical programs to promote best practice information sharing, and to establish measurable outcomes for clinical studies. The OIC also serves as a repository of enterprise pilots and programs intended to improve the member's health outcomes.

•	Promotores Health Network (PHN) is a volunteer-driven community health network designed to improve the community's health through health education specific to health conditions impacting their community and providing guidance and linkage to healthcare services and local resources. PHN provides face-to-face education to members where they live, shop, worship and congregate.

•	myStrength ("The health club for your mind") is a web and mobile self-help resource to manage depression, anxiety, substance use, and chronic pain. myStrength empowers members to be active participants in their journey to becoming and staying mentally and physically healthy.

•

OpiEnd is a clinical program designed to identify members at risk for an opioid abuse diagnosis based on a series of critical social and clinical indicators called the Opioid Risk Classification Algorithm (ORCA). Providers will leverage this risk score to flag members for case management and other appropriate interventions. High risk members identified by ORCA will receive educational outreach to provide evidenced-based resources to support pain addiction.

Providers

For each of our service areas, we establish a provider network consisting of primary and specialty care physicians, hospitals and ancillary providers. Our network of primary care physicians is a critical component of care delivery, cost management and the attraction and retention of new members. Primary care physicians include family and general practitioners, pediatricians, internal medicine physicians and obstetricians and gynecologists. Specialty care physicians provide medical care to members generally upon referral by primary care physicians. Specialty care physicians include, but are not limited to, orthopedic surgeons, cardiologists and otolaryngologists. We also provide education and outreach programs to inform and assist members in accessing quality, appropriate healthcare services.

Our health plans facilitate access to healthcare services for our members primarily through contracts with our providers. Our contracts with primary and specialty care physicians and hospitals usually are for one to three-year periods and renew automatically for successive one-year terms, but generally are subject to termination by either party upon prior written notice. In the absence of a contract, we typically pay providers at applicable state or federal reimbursement levels, depending on the product (e.g., Medicaid or Medicare). We pay providers under a variety of methods, including fee-for-service, capitation arrangements, and value-based arrangements.

•	Under our fee-for-service contracts with providers, we pay a negotiated fee for covered services. This model is characterized as having no financial risk for the provider.

•

Under our capitated contracts, providers can be paid a set amount for their services as outlined in their respective provider agreements. A provider group's financial instability or failure to pay secondary providers for services rendered could lead secondary providers to demand payment from us, even though we have made our regular capitated payments to the provider group. Depending on state law and the regulatory environment, it may be necessary for us to pay such claims.

•	Under value-based arrangements, providers can be paid under either a capitated or fee-for-service model. The arrangement, however, contains provisions for additional payments to the providers or reimbursement from the providers based upon their performance in cost and quality measures.

In addition, we maintain a network of qualified physicians, facilities, and ancillary providers in the prime service areas of our TRICARE contract. Services are provided on a fee-for-service basis.

We often start our provider relationships in a pay-for-performance arrangement before we transition to a risk-sharing arrangement, which is based on the total cost of care. As we advance along this continuum, it strengthens our partnerships with our providers, enabling the delivery of high quality care.

We work with physicians to help them operate efficiently by providing actionable financial and utilization information, physician and patient educational programs and disease and population health management programs. Our programs are also designed to help physicians coordinate care rendered by other providers.

We believe our local and collaborative approach with physicians and other providers gives us a competitive advantage in entering new markets. Our physicians serve on local committees that assist us in implementing preventive care programs, managing costs and improving the overall quality of care delivered to our members, while also simplifying the administrative burdens on our providers. This approach has enabled us to strengthen our provider networks through improved physician recruitment and retention that, in turn, have helped to increase our membership base. The following are among the services we provide to support physicians:

•

Provider Engagement Performance Tools and Processes lead to measurable improvements in quality and health outcomes, healthcare costs, and member satisfaction. High quality and service levels are important as our key customers are increasingly using performance-based measures to select and pay health plans. We have rolled out a suite of network performance tools for use by physicians and other providers which monitor the outcomes and care gaps of their individual patient panels. We meet with the providers to review their performance issues and recommend strategies for improvements in their patient panel outcomes. Our tools also allow the physician and others to see where they stand within their value-based contract.

•

Integrated Care Model is member-centric and managed by one care manager assigned to a member who looks at the total care for the member in a holistic manner. This single care manager will coordinate all care for that member including behavioral health, medical health, and home-based primary care in accordance with an individualized, integrated care plan. This care manager also coordinates meetings with the member's integrated care team to assess and alter the care plan as needed. This results in better outcomes and improvement in member satisfaction.

•

Provider Portal provides claims and eligibility research, prior authorizations, member panels, care gaps, patient analytics, and provider analytics meant to drive provider engagement and improved patient outcomes. Data and reporting are delivered via a secure, user-friendly web-based provider portal. This is all provided through our suite of proprietary technology, including Interpreta and Casenet.

Our contracted physicians also benefit from several of the services offered to our members, including the MemberConnections, EPSDT case management and population health management programs. For example, the MemberConnections staff facilitates doctor/patient relationships by connecting members with physicians, the EPSDT programs encourage routine checkups for children with their physicians and the population health management programs assist physicians in managing their patients with chronic disease.

Where appropriate, our health plans contract with our specialty services organizations to provide services and programs such as care management software, dental benefits management, home-based primary care services, life and population health management, managed vision, pharmacy benefits management, specialty pharmacy and telehealth services. When necessary, we also contract with third-party providers on a negotiated fee arrangement for physical therapy, home healthcare, diagnostic laboratory tests, x-ray examinations, transportation, ambulance services and durable medical equipment.

Quality Management

Our population health programs focus on improving quality of care in areas that have the greatest impact on our members. We employ strategies, including complex case management, which are adjusted for implementation in our individual markets by a system of physician committees chaired by local physician leaders. This process promotes physician participation and support, both critical factors in the success of any clinical quality improvement program.

We have implemented specialized information systems to support our medical quality management activities. Information is drawn from our data warehouse, clinical databases and our membership and claims processing system to identify opportunities to improve care and to track the outcomes of the interventions implemented to achieve those improvements. Some examples of these programs include:

•	use of nationally recognized InterQual or Milliman criteria to help ensure our members receive the right level of care in the most appropriate setting;

•	pre-authorized high-risk medication and services that are commonly over or inappropriately prescribed;

•	member education and the provision of appropriate and easily accessed urgent care services to help members avoid unnecessary and costly emergency department visits and improve their healthcare experience;

•	emphasis on care management and care coordination where clinicians, such as nurses and social workers who are employed to assist high-risk and other selected members with the coordination of healthcare services that meet their specific needs;

•	disease management for chronic illnesses, such as asthma and diabetes through a comprehensive, multidisciplinary and collaborative approach;

•	prenatal case management for women with high-risk pregnancies to help them deliver full-term, healthy infants; and

•	pharmacy treatment compliance programs driven by evidence-based clinical policies and focused on identifying the appropriate medication in the correct dose, delivered in an efficient format and utilized for the correct duration.

We provide reporting on a regular basis using our data warehouse. State and Health Employer Data and Information Set (HEDIS) reporting constitutes the core of the information base that drives our clinical quality performance efforts. This reporting is monitored by Plan Quality Improvement Committees and our corporate population health management and quality improvement teams.

In an effort to ensure the quality of our provider networks, we verify the credentials and background of our providers using standards that are supported by the NCQA.

It is our objective to provide access to the highest quality of care for our members. As a validation of that objective, we pursue accreditation by independent organizations that have been established to promote healthcare quality. The NCQA Health Plan Accreditation and URAC Health Plan Accreditation programs provide unbiased, third party reviews to verify and publicly report results on specific quality care metrics. While we have achieved or are pursuing accreditation for all of our plans, accreditation is only one measure of our ability to provide access to quality care for our members. We have received NCQA health plan accreditation in 23 of 25 eligible states and are pursing accreditation in the remaining two states.

CMS developed the Medicare Advantage Star ratings system to help consumers choose among competing plans, awarding between 1.0 and 5.0 stars to Medicare Advantage plans based on performance in certain measures of quality.

For the 2019 Star rating (calculated in 2018 for the quality bonus payment in 2020), our California and Health Net Oregon contracts received 4.0 out of 5.0 Stars. The Texas D-SNP, Florida D-SNP, Wisconsin D-SNP, and Arizona D-SNP contracts were measured at 3.5 Stars, and our Arizona HMO and Oregon Trillium contracts received 3.0 Stars. In addition, for the 2019 Star rating, we carry a 4.0 Star parent organization rating. Approximately 86% of our Medicare members are in a 4 star or above plan for the 2020 bonus year.

For the 2020 Star rating (calculated in 2019 for the quality bonus payment in 2021), our Texas D-SNP and Wisconsin D-SNP contracts received a 4.5 out of 5.0 Stars, and our California contracts received 4.0 Stars. The Oregon, New York, and Arkansas contracts measured at 3.5 Stars, and our Arizona, Florida, Texas HMO, South Carolina, and Georgia contracts received 3.0 Stars. In addition, for the 2020 Star rating, we carry a 3.5 Star parent organization rating. Approximately 46% of our Medicare members are in a 4 star or above plan for the 2021 bonus year.

We remain committed to our quality initiatives and expect to return to a 4.0 Star parent rating in the future. The parent organization Star rating is used for new Medicare contracts, while existing contracts follow their individual Star ratings to determine bonus payments.

CORPORATE COMPLIANCE

Our Ethics and Compliance program assists the organization in developing effective internal controls that promote prevention and detection of fraud, waste and abuse and resolution of instances of conduct that do not conform to federal and state law and private payor healthcare program requirements, as well as our own ethics and business policies. Responsibilities also include the ongoing maintenance of our privacy program and oversight of the Health Insurance Portability and Accountability Act (HIPAA) as they pertain to us and our business units from a compliance, business, and technical perspective.

Three standards by which corporate compliance programs in the healthcare industry are measured are the Federal Organizational Sentencing Guidelines, the CMS Chapter Guidance and the Compliance Program Guidance series issued by the Department of Health and Human Services' Office of the Inspector General (OIG). Our program contains each of the seven elements suggested by these authorities. These key components are:

•	written standards of conduct;

•	designation of compliance officers and compliance committees;

•	effective training and education;

•	effective lines for reporting and communication;

•	enforcement of standards through well-publicized disciplinary guidelines and actions;

•	internal monitoring and auditing; and

•	prompt response to detected offenses and development of corrective action plans.

The goal of our program is to build a culture of ethics and compliance, which is assessed periodically to measure the values and engagement of the organization. Our Corporate Compliance intranet site, accessible to all employees, contains our Business Ethics and Code of Conduct, Compliance Program description and resources for employees to report concerns or ask questions. If needed, employees have access to the contact information for our Board of Directors' Audit Committee Chairman to report concerns. Our Ethics and Compliance Helpline is a toll-free number and web-based reporting tool operated by a third party independent of the Company and allows employees or other persons to report suspected incidents of misconduct, fraud, waste, abuse or other compliance violations anonymously. Furthermore, our Board of Directors has established a Corporate Compliance Committee that, among other things, reviews ethics and compliance reports on a quarterly basis.

ENVIRONMENTAL, SOCIAL, GOVERANANCE AND CORPORATE RESPONSIBILITY

Our purpose is transforming the health of the community, one person at a time. The ultimate foundation of everything we do is centered on our purpose and the pillars that set us apart as a company: our focus on individuals, commitment to whole health, and active local involvement. With more than three decades of experience operating government-sponsored programs, we understand the importance of how environmental, including climate considerations, and social factors impact the long-term health and well-being of people. Our mission to attain better health outcomes at lower costs is supported by our culture of sound corporate governance to ensure quality, accessible, and affordable healthcare is available for all. Environmental consciousness, social responsibility, and sound governance have been guiding principles of our business since our humble beginnings launched by a former hospital bookkeeper, Elizabeth 'Betty' Brinn, in Milwaukee, Wisconsin. Betty's experience growing up in an orphanage enabled her to see an opportunity to make a difference in healthcare by focusing on the unique needs of the individual - including focusing on ensuring a healthy living environment and meeting social needs, such as employment opportunities, access to transportation, food and education. Corporate social responsibility is at the core of who we are and what we do. Our commitment to environmental, social, and governance matters and corporate responsibility are a living expression of our purpose as we strive to transform the health of our communities, one person at a time. In 2019, we communicated our commitment to corporate social responsibility efforts in five key areas: sustainability, governance, employee partnership, philanthropy, and community outreach and support, with special focus on the social determinants of health, which our founder, Betty Brinn, recognized as crucial to health and well-being in 1984. These five areas reflect Centene's long-term vision and full commitment to the communities we serve and those we will serve in the future. We understand the growing need to proactively address environmental challenges and climate-related factors to support the health of people today and for generations to come. We recognize the importance in providing clear and transparent information on our activities, initiatives, and plans related to environmental, social, and governance (ESG) topics.

COMPETITION

We operate in a highly competitive environment in an industry subject to ongoing significant changes, including business consolidations, new strategic alliances, market pressures, and regulatory and legislative reform both at the federal and state level. This includes, but is not limited to, the federal and state healthcare reform legislation described under the heading "Regulation." In addition, changes to the political environment may drive additional changes to the competitive landscape.

In our business, our principal competitors for customers, members, and providers consist of the following types of organizations:

•	Medicaid Managed Care Organizations that focus on providing healthcare services to Medicaid recipients. These organizations consist of national and regional organizations, as well as not-for-profits and organizations that operate in a small geographic location and are owned by providers, primarily hospitals.

•

National and Regional Commercial Managed Care Organizations that have Medicaid, Medicare and correctional members in addition to members in private commercial plans. Some of these organizations offer a range of specialty services including pharmacy benefits management, behavioral health management, population health management, correctional healthcare management, and nurse triage call support centers.

•	Primary Care Case Management Programs that are established by the states through contracts with primary care providers. Under these programs, physicians provide primary care services to Medicaid recipients, as well as limited population health management oversight.

•	Accountable Care Organizations that consist of groups of doctors, hospitals, and other healthcare providers, who come together to provide coordinated high quality care to their patients.

We compete with other Managed Care Organizations and specialty companies for state, county, federal, and commercial contracts. In addition, the impact of the ACA and potential growth in our segment may attract new competitors including technology companies, new joint ventures, financial services firms, consulting firms and other non-traditional competitors. Before granting a contract, state and federal government agencies consider many competitive factors. These factors include quality of care, financial condition, stability and resources, and established or scalable infrastructure with a demonstrated ability to deliver services and establish comprehensive provider networks. Our specialty companies compete with other providers, such as disease management companies, individual health insurance companies, and pharmacy benefits managers for non-governmental contracts.

We also compete to enroll new members and retain existing members. People who wish to enroll in a managed healthcare plan or to change healthcare plans typically choose a plan based on the quality of care and services offered, ease of access to services, a specific provider being part of the network and the availability of supplemental benefits. We believe that the principal competitive features affecting our ability to retain and increase membership include the range and prices of benefit plans offered, size and quality of provider network, quality of service, responsiveness to customer demands, financial stability, comprehensiveness of coverage, diversity of product offerings, market presence and reputation. The relative importance of each of these factors and the identity of our key competitors varies by market and product. We believe that we compete effectively against other healthcare industry participants.

We also compete with other managed care organizations in establishing provider networks. When contracting with various health plans, we believe that providers consider existing and potential member volume, reimbursement rates, population health management programs, speed of reimbursement and administrative service capabilities. See "Risk Factors - Competition may limit our ability to increase penetration of the markets that we serve."

The relative importance of each of the aforementioned competitive factors and the identity of our key competitors varies by market, including by geography and by product.

REGULATION

Our operations are comprehensively regulated at local, state, and federal levels. Government regulation of the provision of healthcare products and services is a changing area of law that varies from jurisdiction to jurisdiction. States have implemented National Association of Insurance Commissioners (NAIC) model regulations, requiring governance practices and risk and solvency assessment reporting. States have adopted these or similar measures to enhance regulations relating to corporate governance and internal controls of HMOs and insurance companies. We are required to maintain a risk management framework and file reports with state insurance regulators.

Regulatory agencies generally have substantial discretion to issue regulations and interpret and enforce laws and rules. Changes in the regulatory environment and applicable laws and rules also may occur periodically, including in connection with changes in political party or administration at the state and federal levels. For example, the current administration and certain members of Congress have indicated that they may continue to pursue significant amendments to the ACA. Even if the ACA is not amended or repealed, the current administration could propose changes impacting implementation of the ACA. In December 2018, a partial summary judgment ruling in Texas v. United States of America held that the ACA's individual mandate requirement was essential to the ACA, and without it, the remainder of the ACA was invalid (i.e., that it was not "severable" from the ACA). That decision was appealed to the Fifth Circuit, which ruled in December 2019 that the individual mandate was unconstitutional after Congress eliminated the individual mandate penalty, and remanded the case to the district court for additional analysis on the question of severability. The ACA remains in effect until judicial review of the decision is concluded. The ultimate content, timing or effect of any potential future legislation enacted under the current administration remains uncertain.

The ACA transformed the U.S. healthcare system through a series of complex initiatives. Some of the ACA's most significant provisions include the imposition of significant fees, assessments and taxes, including the non-deductible tax (technically called a "fee") on health insurers based on prior year net premiums written (the "health insurer fee" or "HIF"); the establishment of federally-facilitated and state-based Health Insurance Marketplaces where individuals and small groups may purchase health coverage; the implementation of certain premium stabilization programs designed to apportion risk amongst insurers; and the optional Medicaid Expansion. State and federal regulators have continued to provide additional guidance and specificity to the ACA, and we continue to monitor this new information and evaluate its potential impact on our business. For a further discussion of the implementation of the ACA, as well as the potential repeal of, or changes to, the ACA, see "Risk Factors - The implementation of Health Reform Legislation, as well as potential repeal of or changes to Health Reform Legislation, could materially and adversely affect our results of operations, financial position and cash flows" below.

Our regulated subsidiaries are licensed to operate as health maintenance organizations (HMOs), preferred provider organizations (PPOs), third party administrators, utilization review organizations, pharmacies, direct care providers and/or insurance companies in their respective states. In each of the jurisdictions in which we operate, we are regulated by the relevant insurance, health and/or human services departments, departments of insurance, boards of pharmacy and other healthcare providers, and departments of health that oversee the activities of managed care organizations and health plans providing or arranging to provide services to enrollees.

The process for obtaining authorization to operate as a managed care organization, health insurance plan, pharmacy or provider organization is complex and requires us to demonstrate to the regulators the adequacy of the health plan's organizational structure, financial resources, utilization review, quality assurance programs, proper billing, complaint procedures, and an adequate provider network and procedures for covering emergency medical conditions. For example, under both state managed care organization statutes and insurance laws, our health plan subsidiaries, as well as our applicable specialty companies, must comply with minimum statutory capital and other financial solvency requirements, such as deposit and surplus requirements. Insurance regulations may also require prior state approval of acquisitions of other managed care organization businesses and the payment of dividends, as well as notice for loans or the transfer of funds. Our subsidiaries are also subject to periodic state and federal reporting requirements. In addition, each health plan and individual healthcare provider must meet criteria to secure the approval of state regulatory authorities before implementing certain operational changes, including without limitation changes to existing offerings, the development of new product offerings, certain organizational restructurings and, in some states, the expansion of service areas.

States have adopted a number of regulations that may affect our business and results of operations. These regulations in certain states include:

•	premium taxes or similar assessments imposed on us;

•	stringent prompt payment laws requiring us to pay claims within a specified period of time;

•	disclosure requirements regarding provider fee schedules and coding procedures; and

•	programs to monitor and supervise the activities and financial solvency of provider groups.

Federal law has also implemented other health programs that are partially funded by the federal government, such as the Medicaid program. Our Medicaid programs are regulated and administered by various state regulatory bodies. Federal funding remains critical to the viability of these programs. Federal law permits the federal government to oversee and, in some cases, to enact, regulations and other requirements that must be followed by states with respect to these programs. Medicaid is administered at the federal level by CMS. Comprehensive legislation, specifically Title XVIII of the Social Security Act, governs our Medicare program. In addition, our Medicare contracts are subject to regulation by CMS. CMS has the right to audit Medicare contractors and the healthcare providers and administrative contractors who provide certain services on their behalf to determine the quality of care being rendered and the degree of compliance with CMS contracts and regulations.

We are regulated as an insurance holding company and are subject to the insurance holding company acts of the states in which our insurance company and HMO subsidiaries are domiciled. These acts contain certain reporting requirements as well as restrictions on transactions between an insurer or HMO and its affiliates. These holding company laws and regulations generally require insurance companies and HMOs within an insurance holding company system to register with the insurance department of each state where they are domiciled and to file with those states' insurance departments reports describing capital structure, ownership, financial condition, intercompany transactions and general business operations. In addition, depending on the size and nature of the transaction, there are various notice and reporting requirements that generally apply to transactions between insurance companies and HMOs and their affiliates within an insurance holding company structure. Some insurance holding company laws and regulations require prior regulatory approval or, in certain circumstances, prior notice of certain material intercompany transfers of assets as well as certain transactions between insurance companies, HMOs, their parent holding companies and affiliates. Among other provisions, state insurance and HMO laws may restrict the ability of our regulated subsidiaries to pay dividends.

Additionally, the holding company regulations of the states in which our subsidiaries are domiciled restrict the ability of any person to obtain control of an insurance company or HMO without prior regulatory approval. Under those statutes, without such approval or an exemption, no person may acquire any voting security of an insurance holding company, which controls an insurance company or HMO, or merge with such a holding company, if as a result of such transaction such person would "control" the insurance holding company. "Control" is generally defined as the direct or indirect power to direct or cause the direction of the management and policies of a company and is presumed to exist if a person directly or indirectly owns or controls 10% or more of the voting securities of a company.

PPO regulation also varies by state and covers all or most of the subject area referred to above.

Our pharmacies must be licensed to do business as pharmacies in the states in which they are located. Our pharmacies must also register with the U.S. Drug Enforcement Administration and individual state controlled substance authorities to dispense controlled substances. In many of the states where our pharmacies deliver pharmaceuticals, there are laws and regulations that require out-of-state mail order pharmacies to register with that state's board of pharmacy or similar regulatory body. These states generally permit the pharmacy to follow the laws of the state in which the mail order pharmacy is located, although some states require that we also comply with certain laws in that state.

Our healthcare providers must be licensed to practice medicine and do business as care providers in the state in which they are located. In addition, they must be in good standing with the applicable medical board, board of nursing or other applicable entity. Furthermore, they cannot be excluded from participation at either the state or federal levels. Our facilities are periodically reviewed by state departments of health and other regulatory agencies to ensure the environment is safe to provide care.

We must also comply with laws and regulations related to the award, administration and performance of U.S. Government contracts. Government contract laws and regulations affect how we do business with our customers and, in some instances, impose added costs on our business. Money laundering is a method of attempting to conceal the origins of money gained through illegal activity and is itself a crime that can result in substantial criminal and civil sanctions including fines and imprisonment. To ensure compliance with anti-money laundering laws and regulations, it is our policy to conduct business only with legitimate customers and counterparties whose funds are derived from legitimate commercial activity. In addition, as a result of our international operations, we are also subject to the U.S. Foreign Corrupt Practices Act (FCPA) and similar worldwide anti-corruption laws, including the U.K. Bribery Act of 2010, which generally prohibit companies and their intermediaries from making improper payments to non-U.S. officials for the purpose of obtaining or retaining business. A violation of specific laws and regulations by us and/or our agents could result in, among other things, the imposition of fines and penalties on us, changes to our business practices, the termination of our contracts or debarment from bidding on contracts.

State and Federal Contracts

In addition to being a licensed insurance company or HMO, in order to be a Medicaid managed care organization in each of the states in which we operate, we generally must operate under a contract with the state's Medicaid agency. States generally either use a formal proposal process, reviewing a number of bidders, or award individual contracts to qualified applicants that apply for entry to the program. Under these state Medicaid program contracts, we receive monthly payments based on specified capitation rates determined on an actuarial basis. These rates differ by membership category and by state depending on the specific benefits and policies adopted by each state. In addition, several of our Medicaid contracts require us to maintain Medicare Advantage special needs plans, which are regulated by CMS, for dual eligible individuals within the state. We also contract with states to provide healthcare services to correctional facilities.

We provide Medicare Advantage, Dual Eligible Special Needs Plans (D-SNPs), and Medicare-Medicaid Plans (MMP) which are provided under contracts with CMS and subject to federal regulation regarding the award, administration and performance of such contracts. CMS also has the right to audit our performance to determine our compliance with these contracts, as well as other CMS regulations and the quality of care we provide to Medicare beneficiaries under these contracts. We additionally provide behavioral and other healthcare services to correctional systems under contracts in certain states which are also subject to state regulation.

Our government contracts include government-sponsored managed care and administrative services contracts through the TRICARE program, the DoD Military and Family Life Counseling program, and certain other healthcare-related government contracts.

Our state and federal contracts and the regulatory provisions applicable to us generally set forth the requirements for operating in the Medicaid and Medicare sectors, including provisions relating to:

•	eligibility, enrollment and dis-enrollment processes;

•	covered services;

•	eligible providers;

•	subcontractors;

•	record-keeping and record retention;

•	periodic financial and informational reporting;

•	quality assurance;

•	accreditation;

•	health education and wellness and prevention programs;

•	timeliness of claims payment;

•	financial standards;

•	safeguarding of member information;

•	fraud, waste and abuse detection and reporting;

•	grievance procedures; and

•	organization and administrative systems.

A health plan or individual health insurance provider's compliance with these requirements is subject to monitoring by state regulators and by CMS. A health plan is also subject to periodic comprehensive quality assurance evaluations by a third-party reviewing organization and generally by the insurance department of the jurisdiction that licenses the health plan. A health plan or individual health insurance provider must also submit reports to various regulatory agencies, including quarterly and annual statutory financial statements and utilization reports.

Our health plans operate through individual state contracts, generally with an initial term of one to five years. The contracts often have renewal or extension terms or are renewable through the state's reprocurement process. The contracts generally are subject to termination for cause, an event of default or lack of funding, among other things.

Marketplace Contracts

We operate in 20 states under federally-facilitated and state-based marketplace contracts with CMS that expire annually.

We operate under a contract with the Arkansas Department of Human Services Division of Medical Services and the Arkansas Insurance Department to participate in the Medicaid expansion model that Arkansas has adopted (referred to as "Arkansas Works").

Privacy Regulations

We are subject to various international, federal, state and local laws and rules regarding the use, security and disclosure of protected health information, personal information, and other categories of confidential or legally protected data that our businesses handle. Such laws and rules include, without limitation, the Health Insurance Portability and Accountability Act (HIPAA), the Federal Trade Commission Act, the Gramm-Leach-Bliley Financial Modernization Act of 1999 (Gramm-Leach-Bliley Act), the General Data Protection Regulation (GDPR) in the European Union (EU), and state privacy and security laws such as the California Confidentiality of Medical Information Act and the California Online Privacy Protection Act. Privacy and security laws and regulations often change due to new or amended legislation, regulations or administrative interpretation. A variety of state and federal regulators enforce these laws, including but not limited to the U.S. Department of Health and Human Services (HHS), the Federal Trade Commission, state attorneys general and other state regulators.

HIPAA is designed to improve the portability and continuity of health insurance coverage, simplify the administration of health insurance through standard transactions and ensure the privacy and security of individual health information. Among the requirements of HIPAA are the Administrative Simplification provisions which include: standards for processing health insurance claims and related transactions (Transactions Standards); requirements for protecting the privacy and limiting the use and disclosure of medical records and other personal health information (Privacy Rule); and standards and specifications for safeguarding personal health information which is maintained, stored or transmitted in electronic format (Security Rule). The Health Information Technology for Economic and Clinical Health (HITECH) Act amended certain provisions of HIPAA and enhanced data security obligations for covered entities and their business associates. HITECH also mandated individual notifications in instances of a data breach, provided enhanced penalties for HIPAA violations, and granted enforcement authority to states' Attorneys Generals in addition to the HHS Office for Civil Rights. The HIPAA Omnibus Rule further enhanced the changes under the HITECH Acts and the Genetic Information Nondiscrimination Act of 2008 (GINA) which clarified that genetic information is protected under HIPAA and prohibits most health plans from using or disclosing genetic information for underwriting purposes. These regulations also establish significant criminal penalties and civil sanctions for non-compliance. The preemption provisions of HIPAA provide that the federal standards will not preempt state laws that are more stringent than the related federal requirements.

The Privacy and Security Rules and HITECH/Omnibus enhancements established requirements to protect the privacy of medical records and safeguard personal health information maintained and used by healthcare providers, health plans, healthcare clearinghouses, and their business associates.

The Security Rule requires healthcare providers, health plans, healthcare clearinghouses, and their business associates to implement administrative, physical and technical safeguards to ensure the privacy and confidentiality of health information electronically stored, maintained or transmitted. The HITECH Act and Omnibus Rule enhanced a federal requirement for notification when the security of protected health information is breached. In addition, there are state laws that have been adopted to provide for, among other things, private rights of action for breaches of data security and mandatory notification to persons whose identifiable information is obtained without authorization.

The requirements of the Transactions Standards apply to certain healthcare related transactions conducted using "electronic media." Since "electronic media" is defined broadly to include "transmissions that are physically moved from one location to another using portable data, magnetic tape, disk or compact disk media," many communications are considered to be electronically transmitted. Under HIPAA, health plans and providers are required to have the capacity to accept and send all covered transactions in a standardized electronic format. Penalties can be imposed for failure to comply with these requirements. The transaction standards were modified on October 1, 2015 with the implementation of the ICD-10 coding system.

In addition, we process and maintain personal card data, particularly in connection with our Marketplace business. As a result, we must maintain compliance with the Payment Card Industry (PCI) Data Security Standard, which is a multifaceted security standard intended to optimize the security of credit, debit and cash card transactions and protect cardholders against misuse of their personal information.

Other Fraud, Waste and Abuse Laws

Investigating and prosecuting healthcare fraud, waste and abuse continues to be a top priority for state and federal law enforcement entities. The focus of these efforts has been directed at Medicare, Medicaid, Health Insurance Marketplace and commercial products. The fraud, waste and abuse laws include the federal False Claims Act, which prohibits the known filing of a false claim or the known use of false statements to obtain payment from the federal government. Many states have false claim act statutes that closely resemble the federal False Claims Act. The laws and regulations relating to fraud, waste and abuse and the requirements applicable to health plans and providers participating in these programs are complex and change regularly. Compliance with these laws may require substantial resources. We are constantly looking for ways to improve our fraud, waste and abuse detection methods. While we have both prospective and retrospective processes to identify abusive patterns and fraudulent billing, we continue to increase our capabilities to proactively detect inappropriate billing prior to payment.

EMPLOYEES

As of December 31, 2019, we had approximately 56,600 employees. We believe our relationships with our employees are positive.
