Non-GAAP Financial Presentation

The Company is providing certain non-GAAP financial measures in this report as the Company believes that these figures are helpful in allowing investors to more accurately assess the ongoing nature of the Company's operations and measure the Company's performance more consistently across periods. The Company uses the presented non-GAAP financial measures internally to allow management to focus on period-to-period changes in the Company's core business operations. Therefore, the Company believes that this information is meaningful in addition to the information contained in the GAAP presentation of financial information. The presentation of this additional non-GAAP financial information is not intended to be considered in isolation or as a substitute for the financial information prepared and presented in accordance with GAAP.

Specifically, the Company believes the presentation of non-GAAP financial information that excludes Health Net acquisition related expenses, amortization of acquired intangible assets, as well as other items, allows investors to develop a more meaningful understanding of the Company's performance over time. The tables below provide reconciliations of non-GAAP items ($ in millions, except per share data):

PART I

ITEM 1. Business

OVERVIEW

We are a diversified, multi-national healthcare enterprise that provides a portfolio of services to government sponsored healthcare programs, focusing on under-insured and uninsured individuals. We provide member-focused services through locally based staff by assisting in accessing care, coordinating referrals to related health and social services and addressing member concerns and questions. 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 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.

On March 24, 2016, we acquired all of the issued and outstanding shares of Health Net, Inc. (Health Net) a publicly traded managed care organization that delivers healthcare services through health plans and government-sponsored managed care plans. The transaction was valued at approximately $5,990 million, including the assumption of $703 million of outstanding debt. The acquisition allows us to offer a more comprehensive and scalable portfolio of solutions and provides opportunity for additional growth across the combined company's markets.

We operate in two segments: Managed Care and Specialty Services. Our Managed Care segment provides health plan coverage to individuals through government subsidized programs, including Medicaid, that also encompasses the State Children's Health Insurance Program (CHIP), Long Term Care (LTC), Foster Care, dual-eligible individuals (Duals), the Supplemental Security Income Program, also known as the Aged, Blind or Disabled Program (ABD), Medicare, and Health Insurance Marketplace. The Managed Care segment also includes the operations previously included in Health Net's Western Region Operations Segment, with the exception of certain operations of its pharmaceutical services and behavioral health subsidiaries. The portions of Health Net's Western Region Operations segment included in the Managed Care segment consist of the following Health Net operations: commercial, Medicare, Medicaid and dual eligible health plans, primarily in Arizona, California, Oregon and Washington. Our Specialty Services segment consists of our specialty companies offering diversified healthcare services and products to state programs, correctional facilities, healthcare organizations, employer groups and other commercial organizations, as well as to our own subsidiaries. The Specialty Services segment also includes the operations previously included in the Government Contracts segment of Health Net as well as certain operations of its pharmaceutical services and behavioral health subsidiaries, the latter of which Health Net previously included in its Western Region Operations segment. The Government Contracts business includes our government-sponsored managed care support contract with the U.S. Department of Defense (DoD) under the TRICARE program in the North Region, the Military Family and Life Counseling (MFLC) contract with the DoD, and other health care related government contracts, including the Patient Centered Community Care (PC3) with the U.S. Department of Veterans Affairs (VA). For the year ended December 31, 2016, our Managed Care and Specialty Services segments accounted for 92% and 8%, respectively, of our total external revenues.

Our managed care membership totaled 11.4 million as of December 31, 2016. For the year ended December 31, 2016, our total revenues and net earnings from continuing operations attributable to Centene were $40.6 billion and $559 million, respectively, and our total cash flow from operations was $1,851 million.

Our subsidiary, Kentucky Spirit Health Plan (Kentucky Spirit), ceased serving members in Kentucky as of July 6, 2013. Accordingly, the results of operations for Kentucky Spirit are classified as discontinued operations for all periods presented in our consolidated financial statements. The following discussion and analysis, with the exception of cash flow information, is presented in the context of continuing operations unless otherwise identified.

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 corporate office is located at 7700 Forsyth Boulevard, St. Louis, Missouri 63105, and our telephone number is (314) 725-4477. Our stock is publicly traded on the New York Stock Exchange under the ticker symbol “CNC.”

INDUSTRY

We provide a full spectrum of managed healthcare products and services, primarily through Medicaid, which includes CHIP, LTC, Foster Care, Duals, and ABD, Medicare, Health Insurance Marketplace, TRICARE, and other state and federal programs, including programs for the uninsured. We also offer a variety of individual, small group, and large group commercial health care products, both to employers and directly to members.

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 mandated managed care states.  

Established in 1972, and authorized by Title XVI of the Social Security Act of 1935, as amended, 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 because of their critical health issues. 

The Balanced Budget Act of 1997 created 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. Some states include the parents of these children in their CHIP programs. 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.

CMS estimated the total Medicaid market was approximately $545 billion in 2015, and estimate the market will grow to $973 billion by 2025. Medicaid spending increased by 9.7% in 2015 and is projected to increase at an average annual rate of 5.9% between 2016 and 2025.

LTC 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. LTC services are provided for individuals requiring nursing home level of care, receiving waiver services, or who are entitled to state Medicaid LTC benefits. The largest group receiving LTC, by spending, are older individuals and individuals with physical disabilities ($93 billion in 2014), followed by individuals with intellectual and developmental disabilities ($42 billion in 2014), those with serious mental illness and/or serious emotional disturbance ($9 billion in 2014) and other populations ($8 billion in 2014). States are increasingly turning to managed care as a solution to provide coordinated, holistic care to their LTC beneficiaries. According to the National Association of States United for Aging and Disabilities, 22 states utilize some form of LTC up from eight in 2004.

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 rooms, which tends to be more expensive. As a result, many states have found that the costs of providing Medicaid benefits have increased while the medical outcomes for the recipients remained unsatisfactory.

We believe recognition of the value of managed care as a means of delivering improved health outcomes for Medicaid beneficiaries and effectively controlling costs will continue to strengthen. A growing number of states have mandated that their Medicaid recipients enroll in managed care plans. Other states are considering moving to a mandated managed care approach. 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, CHIP, LTC, Foster Care and ABD populations.

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. We provide or arrange health care benefits for services normally covered by Medicare, plus a broad range of health care 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 of 1935, as amended.

A portion of Medicaid 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 10.4 million dual-eligible enrollees in 2016. 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 ABD, LTC, Medicare-Medicaid Plan (MMP) and Medicare Advantage Dual Special Needs Plan 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 Rating (calculated in 2013), Medicare Advantage plans were required to achieve a minimum of 4.0 Stars to qualify for a quality bonus payment in 2016. 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 $646 billion in 2015, and estimate the market will grow to $1.3 trillion by 2025. Medicare spending increased 4.5% in fiscal 2015 and is projected to increase at an average annual rate of 7.1% between 2016 and 2025.

Commercial

We offer commercial health care products to individuals and large and small employer groups as well as products to individuals through the Health Insurance Marketplace. Our health maintenance organization (HMO) plans offer comprehensive benefits generally for a fixed fee or premium that does not vary with the extent or frequency of medical services actually received by the member. We offer HMO 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. When an individual enrolls in one of our HMO plans, he or she selects a primary care physician (PCP) from among the physicians participating in our network. Our preferred provider organization (PPO) plans offer coverage for services received from any health care provider, with benefits generally paid at a higher level when care is received from a participating network provider. Coverage typically is subject to deductibles and copayments or coinsurance. Our point of service (POS) plans and our elect open access (EOA) plans blend the characteristics of HMO, PPO and indemnity plans. Members can have comprehensive HMO-style benefits for services received from participating network providers with lower copayments (particularly within the medical group), but also have coverage, generally at higher copayment or coinsurance levels or with coverage limitations, for services received outside the network. Our Exclusive Provider Organization (EPO) plans and Healthcare Service Plans (HSPs) similarly blend elements of traditional HMO and PPO plans. 

3

In 2010, the Patient Protection and Affordable Care Act and the accompanying Health Care and Education Affordability Reconciliation Act collectively referred to as the Affordable Care Act (ACA), were enacted. While the constitutionality of the ACA was subsequently challenged in a number of legal actions, in June 2012, the Supreme Court upheld the constitutionality of the ACA, with one limited exception relating to the Medicaid expansion provision (Medicaid Expansion). The Supreme Court held that states could not be required to expand Medicaid and risk losing all federal money for their existing Medicaid programs. Under the 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 will pay the entire costs for Medicaid Expansion coverage for newly eligible beneficiaries from 2014 through 2016. Assuming that the current program remains in effect unchanged, in 2017 the federal share is scheduled to decline to 95%; in 2018 it would be 94%; in 2019 it would be 93%; and it would be 90% in 2020 and subsequent years.

Health Insurance Marketplaces 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 and cost-sharing 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 three levels of coverage that vary based on premiums and out-of-pocket costs. Premium subsidies are provided to families without access to other coverage and with incomes between 100-400% of the federal poverty level to help them purchase insurance through the Marketplaces. These subsidies are offered on a sliding scale basis.

OUR COMPETITIVE STRENGTHS

Our approach is based on the following key attributes:

• Strong Historic Operating Performance. We have increased revenues as we have grown in existing markets, expanded into new markets and broadened our product offerings. We entered the Wisconsin market in 1984 as a single health plan and have grown to serve 29 states. Our operating performance has been demonstrated by the following:

	2016		2015		% Change 2015 - 2016
Total membership (in millions)	11.4		5.1		124%
Total revenues ($ in billions)	$	40.6	$	22.8	78%
Net earnings from continuing operations attributable to Centene Corporation ($ in millions)	$	559	$	356	57%
Diluted earnings per share (EPS)	$	3.41	$	2.89	18%
Adjusted Diluted EPS	$	4.43	$	3.14	41%
Adjusted EBITDA	$	1,804	$	921	96%

For the year ended December 31, 2016, total revenues of $40.6 billion produced a five year Compound Annual Growth Rate (CAGR) of 51%.

• 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 platform we have developed for our existing states for configuration into new states or health plan acquisitions. We believe our predictive modeling technology enables our medical 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.

• Expertise in Government Sponsored Programs. For more than 30 years, we have developed a specialized government services expertise that has helped us establish and maintain relationships with members, providers and state governments. We have implemented programs developed to achieve savings for state governments and improve medical outcomes for members by reducing inappropriate emergency room use, inpatient days and high cost interventions, as well as by managing care of chronic illnesses. We work with state agencies in order to maximize the effectiveness of their programs. Our approach is to accomplish this while maintaining adequate levels of provider compensation and protecting our profitability.

• Diversified Business Lines. We continue to broaden our service offerings to address areas that we believe have been traditionally under-served by Medicaid managed care organizations. In addition to our Medicaid and Medicaid-related managed care services, our service offerings include behavioral health management, care management software, correctional healthcare services, dental benefits management, Commercial, in-home health services, life and health management, managed vision, pharmacy benefits management, specialty pharmacy and telehealth services. With the acquisition of Health Net, we further broadened our service offerings in 2016, which added government-sponsored care under its federal contracts with the Department of Defense and the U.S. Department of Veterans Affairs (VA), as well as Medicare Advantage. 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.

• 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 Medicaid and specialty services while maintaining our local accountability and improved access.

• Quality and Innovation. Our innovative medical 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 CentAccount program, Start Smart For Your Baby, and MemberConnections.

OUR BUSINESS STRATEGY

Key components of our current business strategy include: 

• Increase Penetration of Existing State Markets. We seek to continue to increase our Medicaid and Medicare membership in states in which we currently operate through alliances with key providers, outreach efforts, development and implementation of community-specific products and acquisitions. For example, in 2016, we began serving the STAR Kids Medicaid population in seven delivery areas in Texas. In 2017, we expect to expand our Medicare Advantage footprint into four of our existing states.

• Diversify Business Lines. We seek to broaden our business lines into areas that complement our existing business to enable us to grow and diversify our revenue. In 2016, we served managed care members in 24 states through over 250 product solutions. We are constantly evaluating new opportunities for expansion both domestically and abroad. For example, in 2016, we acquired Health Net, which broadened our service offerings and added government-sponsored care. We employ a disciplined acquisition strategy that is based on defined criteria including internal rate of return, accretion to earnings per share, market leadership and compatibility with our information systems. We engage our executives in the relevant operational units or functional areas to ensure consistency between the diligence and integration process.

• Address Emerging State Needs. We work to assist the states in which we operate in addressing the operating challenges they face. We seek to assist the states in balancing premium rates, benefit levels, member eligibility, policies and practices, provider compensation and minimizing fraud, waste, and abuse. By helping states structure appropriate programs to cover a wide range of populations including Medicaid, CHIP, LTC, ABD, IDD, and specialty services, among others. We seek to ensure that we are able to continue to provide those services on terms that achieve targeted gross margins, provide an acceptable return and grow our business.

• Develop and Acquire Additional Markets. We continue to leverage our experience to identify and develop new domestic and international markets by seeking both to acquire existing business and to build our own operations. Domestically, we focus expansion in states where Medicaid recipients are mandated to enroll in managed care organizations because we believe member enrollment levels are more predictable in these states. In addition, we provide solutions to states looking to deliver the highest quality of care within their budgetary constraints. In 2014, we entered the international market with our investment in Ribera Salud, S.A. (Ribera Salud), a Spanish health management group. In 2015, we began managing care for Medicaid members in Oregon and also began managing care for members who are dually eligible for Medicare and Medicaid in Michigan. In 2016, we increased our ownership interest to 75% in The Practice (Group) Limited (TPG), one of the largest provider networks for NHS England.

• Leverage Established Infrastructure to Enhance Operating Efficiencies. We intend to continue to invest in infrastructure to further drive efficiencies in operations and to add functionality to improve the service provided to members and other organizations at a low cost. Information technology, or IT, investments complement our overall efficiency goals by increasing the automated processing of transactions and growing the base of decision-making analytical tools. We believe that our centralized functions and common systems enable us to add members and markets quickly and economically.

• Maintain Operational Discipline. We seek to operate in markets that allow us to meet our internal metrics including membership growth, plan size, market leadership and operating efficiency. We use multiple techniques to monitor and reduce our medical costs, including on-site hospital review by staff nurses and involvement of medical management in significant cases. Our executive dashboard is utilized to quickly identify cost drivers and medical trends. Our management team regularly evaluates the financial impact of proposed changes in provider relationships, contracts, changes in membership and mix of members, potential state rate changes and cost reduction initiatives. We may divest contracts or health plans in markets where the environment, over a long term basis, does not allow us to meet our targeted performance levels.  For example, due to under performance, we exited the Arizona individual PPO business, effective January 1, 2017. In addition, in 2016, we took various rate and product design actions for 2017 to address issues and improve profitability in connection with certain lines of business acquired with the Health Net acquisition.

Substantially all of our revenue is derived from operations within the United States and its territories, and all of the Company's long lived assets are based in the United States and its territories. We generally receive a fixed premium per member per month pursuant to our state contracts. Our medical costs have a seasonality component due to cyclical illness, for example cold and flu season, resulting in higher medical expenses beginning in the fourth quarter and continuing throughout the first quarter of the following year. Our managed care subsidiaries in California and Texas had revenues from their respective state governments that each exceeded 10% of our consolidated total revenues in 2016. In addition, the federal government is a significant customer to our Specialty Services segment due to our Federal Services business.

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 in working 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 including Start Smart for your Baby, Living Well With Sickle Cell and The CentAccount Program.

• 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.

9

• Fraud, waste and abuse prevention. We have several systems in place to help identify, detect and investigate potential waste, abuse and fraud 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

• laboratory and x-ray services

• home health care

• provision of durable medical equipment

• behavioral health and substance abuse services

• 24-hour nurse advice line

• transportation assistance

• vision care

• dental care

• immunizations

• prescriptions and limited over-the-counter drugs

• specialty pharmacy

• therapies

• social work services

• care coordination

We also provide a comprehensive set of education and outreach programs to inform, assist and incentivize members to access quality, appropriate healthcare services in an efficient manner. Many of these programs have been recognized with awards for their excellence in education, outreach and/or case management techniques including 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 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.

• 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 room 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. NurseWise 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. 

• 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 room 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.

• The Diabetes Management Program is an innovative program that is a collaboration with our life and health management subsidiary and our health plans that targets diabetic patients and educates them on their disease state.

• 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. 

• The CentAccount Program 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.

• Fluvention is an outreach program aimed at educating members on preventing the transmission of the influenza virus by encouraging members to get the seasonal influenza vaccines and take everyday precautions to prevent illness.

• Preventive Care Programs are designed to educate our members on the benefits of Early and Periodic Screening, Diagnosis and Treatment, or 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.

• Clinical Programs Library (CPL) 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 CPL 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.

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 in care delivery, management of costs 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 the 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 two-year periods and renew automatically for successive one-year terms, but generally are subject to termination by either party upon 90 to 120 days prior written notice. In the absence of a contract, we typically pay providers at applicable state or federal reimbursement levels, depending on the product timeline (e.g., Medicaid or Medicare). We pay providers under a variety of methods, including fee-for-service, capitation arrangements, or risk-sharing performance-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 risk-sharing performance-based arrangements, providers are paid under a capitated or fee-for-service arrangement. The arrangement, however, contains provisions for additional payments to the providers or reimbursement from the providers based upon cost and quality measures.

In addition, we maintain a network of qualified physicians, facilities, and ancillary providers in the prime service areas of our T-3 contract for the TRICARE North Region. Services are provided on a fee-for-service basis. We also maintain a provider network in Regions 1, 2, and 4 in support of VA's PC3 program.

We work with physicians to help them operate efficiently by providing financial and utilization information, physician and patient educational programs and disease and medical management programs. Our programs are also designed to help the 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:

• Customized Utilization Reports provide certain of our contracted physicians with information that enables them to run their practices more efficiently and focuses them on specific patient needs. For example, quarterly detail reports update physicians on their status within their risk pools. Equivalency reports provide physicians with financial comparisons of capitated versus fee-for-service arrangements.

• Case Management Support helps the physician coordinate specialty care and ancillary services for patients with complex conditions and direct members to appropriate community resources to address both their health and socio-economic needs.

• Web-based Claims and Eligibility Resources have been implemented to provide physicians with on-line access to perform claims and eligibility inquiries. 

12

Our contracted physicians also benefit from several of the services offered to our members, including the MemberConnections, EPSDT case management and 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 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 behavioral health management, care management software, dental benefits management, in-home health services, life and 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, dental, diagnostic laboratory tests, x-ray examinations, transportation, ambulance services and durable medical equipment.

Quality Management

Our medical management programs focus on improving quality of care in areas that have the greatest impact on our members. We employ strategies, including health management and 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 intervention programs include:

• appropriate leveling of care for neonatal intensive care unit hospital admissions, other inpatient hospital admissions, and observation admissions, in accordance with Interqual or Milliman criteria.

• tightening of our pre-authorization list and more stringent review of durable medical equipment and injectibles.

• Emergency room program designed to collaboratively work with hospitals to steer non-emergency care away from the costly emergency room setting (through patient education, on-site alternative urgent care settings, etc.).

• increase emphasis on case management and clinical rounding where case managers are nurses or social workers who are employed by the health plan to assist selected members with the coordination of healthcare services in order to meet a member's specific healthcare needs.

• incorporation of disease management, which is a comprehensive, multidisciplinary, collaborative approach to chronic illnesses such as asthma and diabetes.

• Start Smart For Your Baby, a prenatal case management program aimed at helping women with high-risk pregnancies deliver full-term, healthy infants.

• Pharmacy treatment compliance programs driven by clinical policy 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, or 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 medical management team. 

In an effort to ensure the quality of our provider networks, we undertake to verify the credentials and background of our providers using standards that are supported by the National Committee for Quality Assurance, or NCQA.

It is our objective to provide access to the highest quality of care for our members.  As a validation of that objective, we often 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 currently have 19 of 26 eligible health plans with NCQA accreditation.

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 2017 Star rating (calculated in 2016 for the quality bonus payment in 2018), our Oregon HMO contract received 4.5 out of 5.0 Stars. The Arizona Bridgeway, California HMO, California PPO, Texas Superior and Wisconsin MHS contracts were measured at 4.0 Stars, our Oregon PPO contract was measured at 3.5 Stars and our Arizona HMO, Ohio Buckeye and Oregon Trillium contracts received 3.0 Stars. In addition, we carry a 4 Star parent organization rating.

SPECIALTY SERVICES

Our specialty services are a key component of our healthcare strategy and complement our core Managed Care business. Our provision of specialty services diversifies our revenue stream, enhances the quality of health outcomes for our members and others, and allows Centene to manage costs. In 2015, we launched Envolve, a new brand that brings together our extensive portfolio of specialty healthcare solutions. Envolve leverages our collective expertise in pharmacy solutions; health, triage, wellness and disease management; and vision and dental services, to provide integrated and comprehensive healthcare for members. Our specialty services are provided primarily as follows: 

• Pharmacy Solutions. Envolve Pharmacy Solutions utilizes innovative, flexible solutions and customized care management. Under the new brand, we will continue to offer traditional pharmacy benefits management as well as comprehensive specialized pharmacy benefit services through our specialty pharmacy, AcariaHealth. Our traditional pharmacy benefits management program offers progressive pharmacy benefits management services that are specifically designed to improve quality of care while containing costs. This is achieved through a low cost strategy that helps optimize clients' pharmacy benefits. Services that we provide include claims processing, pharmacy network management, benefit design consultation, drug utilization review, formulary and rebate management, online drug management tools, mail order pharmacy services, home delivery services, analytics and clinical consulting and patient and physician intervention. AcariaHealth offers specialized care management services for complex diseases and enhances the patient care offering through collaboration with providers and the capture of relevant data to measure patient outcomes. Acquired with the Health Net transaction, Health Net Pharmaceutical Services (HNPS) provides pharmacy benefit management (PBM) services to Medicare and dual eligible members. HNPS manages these benefits in an effort to achieve the highest quality outcomes at the lowest cost for legacy Health Net members. HNPS contracts with national health care providers, vendors, drug manufacturers and pharmacy distribution networks, oversees pharmacy claims and administration, reviews and evaluates new FCA-approved drugs for safety and efficacy and manages data collection efforts to facilitate our health plans' disease management programs.

• Health, Triage, Wellness, and Disease Management Services. Envolve PeopleCare brings together our behavioral health, nurse advice, telehealth, and health, wellness and disease guidance programs, allowing for a focus on individual health management through education and empowerment. Our life and health management programs specialize to encourage healthy behaviors, promote healthier workplaces, improve workforce and societal productivity and reduce healthcare costs. Health risk appraisals, biometric screenings, interactive wellness programs, disease management and work-life/employee assistance services are areas of focus. We utilize telephonic health and work/life balance coaching, in-home and online interactions and informatics processes to deliver effective clinical outcomes, enhanced patient-provider satisfaction and lower overall healthcare costs. We offer telehealth services where members engage with bilingual customer service representatives and nursing staff members who provide health education and triage advice and offer continuous access to health plan functions. Our staff can arrange for urgent pharmacy refills, transportation and qualified behavioral health professionals for crisis stabilization assessments. Our behavioral health networks feature a full range of services and levels of care to help people with mental illness reach their recovery and wellness goals. Acquired with the Health Net acquisition, Managed Health Network, Inc. and its subsidiaries (collectively MHN) administers and arranges behavioral health benefits and services. MHN offers behavioral health and substance abuse programs on an insured and self-funded basis to groups in various states. The programs and services are included as a standard part of most of our commercial health plans and are also sold in conjunction with other commercial and Medicare products and on a stand-alone basis to unaffiliated health plans and employer groups.

• Vision and Dental Services. Envolve Benefit Options coordinates benefits beyond traditional medical benefits to offer fully integrated vision and dental health services. Our vision benefit program administers routine and medical surgical eye care benefits through a contracted national network of eye care providers. Through the dental benefit, we are dedicated to improving oral health through a contracted network of dental healthcare providers.

• Care Management Software. Casenet is a software provider of innovative care management solutions that automate the clinical, administrative and technical components of care management programs, which is used by our health plans and available for sale to third parties.

• Correctional Healthcare Services. Centurion, our joint venture subsidiary with MHM Services Inc., provides comprehensive healthcare services to individuals incarcerated in Massachusetts, Minnesota, Mississippi, Tennessee and Vermont state correctional facilities. In 2016, we began providing healthcare services to individuals incarcerated in Florida and New Mexico.

• In-Home Health Services. U.S. Medical Management, our majority owned subsidiary acquired in January 2014, provides in-home health services for high acuity populations.

• Integrated Long-Term Care. LifeShare provides home and community-based support for people with intellectual and developmental disabilities, children in the child welfare system and people of all ages and abilities, with a focus on those that are often marginalized by society. In addition, LifeShare operates school-based programs that focus on students with special needs.

• Federal Services. Health Net Federal Services, which was acquired with the Health Net acquisition, has a Managed Support Contract in the North Region for the DoD TRICARE program. The services that are provided are structured as cost reimbursement arrangements for health care costs plus administrative fees received in the form of fixed prices, fixed unit prices, and contingent fees and payments based on various incentives and penalties. We provide administrative services to Military Health System eligible beneficiaries, which includes eligible active duty service members and their families, retired service members and their families, survivors of retired service members and qualified former spouses. In July 2016, it was announced that the DoD awarded Health Net Federal Services, the TRICARE West Region contract. In connection with this latest generation of TRICARE contracts, the Department of Defense has consolidated the prior North, South and West TRICARE regions into two: the West and East Regions. We expect health care delivery for this new contract to begin in the second half of 2017. Additionally, our wholly owned subsidiary, MHN Government Services, is party to a MFLC contract that was awarded by the DoD to implement, administer and monitor the non-medical counseling MFLC program. The Patient Centered Community Care (PC3) program, acquired with the Health Net acquisition, provides eligible veterans coordinated, timely access to care through a comprehensive network of non-VA providers who meet VA quality standards when a local VA medical center cannot readily provide the care.

We currently have NCQA accreditation and URAC accreditation for several of our specialty companies.

CORPORATE COMPLIANCE

Our Corporate Ethics and Compliance Program provides controls to help us assure that our values are reflected in everything we do, further enhancing operations, improving access to quality care and helping to safeguard against fraud, waste and abuse.

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 the Sentencing Guidelines and the OIG guidance. These key components are:

• written standards of conduct

• designation of a corporate compliance officer and compliance committee

• effective training and education  

• effective lines for reporting and communication  

• enforcement of standards through well publicized disciplinary guidelines and actions  

• internal monitoring and auditing

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

15

The goal of our program is to build a culture of ethics and compliance, which is assessed periodically to measure the integrity of the organization. Our internal Corporate Compliance intranet site, accessible to all employees, contains our Business Ethics and Conduct Policy (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 the members of our Board of Directors' Audit Committee 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, the Board of Directors has established a Corporate Compliance committee that, among other things, reviews ethics and compliance reports on a quarterly basis.

COMPETITION

We operate in a highly competitive environment in an industry subject to ongoing significant changes resulting from the ACA, business consolidations, new strategic alliances, market pressures, and regulatory and legislative reform including but not limited to the federal and state health care reform legislation described under the heading "Regulation." In addition, changes to the political environment, including recent changes resulting from the 2016 election cycle and related uncertainties, 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 focus on providing healthcare services to Medicaid recipients. These organizations consist of national and regional organizations, as well as not-for-profits and smaller organizations that operate in one city or state and are owned by providers, primarily hospitals.

• National and Regional Commercial Managed Care Organizations have Medicaid and Medicare 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, health management, and nurse triage call support centers.

• Primary Care Case Management Programs are programs 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 medical management oversight.     

• Accountable Care Organizations are groups of doctors, hospitals, and other health care providers, who come together to give coordinated high quality care to their patients.

We compete with other managed care organizations and specialty companies for state, federal, and commercial contracts. Before granting a contract, state and federal government agencies consider many 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 adequate 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 health care 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, medical 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.”

16

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 both 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. 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, federal or national level. For example, the new administration and certain members of Congress have affirmatively indicated that they will pursue full repeal of or significant amendment to the ACA. Even if the ACA is not amended or repealed, the new administration could propose changes impacting implementation of the ACA. The ultimate content and timing of any legislation enacted under the new administration that would impact the current implementation of the ACA remains uncertain.

The ACA transformed the U.S. health care 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 the risk factor below entitled “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.”

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 health care 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 and provider organizations 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, complaint procedures, provider network and procedures for covering emergency medical conditions. 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 health care 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.

17

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 of 1935, as amended, 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 health care 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 acts 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 health care 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 both the state and 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, and are faceted by, 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. 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.

18

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 use either 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 Department of Defense Military and Family Life Counseling program, the U.S. Department of Veterans Affairs Patient Centered Community Care program and certain other health care-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

• 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.

Marketplace Contracts

We operate in 15 states under federally facilitated and state-based Marketplace contracts with CMS that expire annually.  In 2016, we began operating in a federally facilitated Marketplace in New Hampshire, as well as Arizona and California that were added with the Health Net Acquisition.

In addition, 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"). In 2016, we started operating under a contract with the New Hampshire Department of Health and Human Services to participate in the Medicaid expansion model that New Hampshire has adopted (referred to as the “Premium Assistance Program”).

Privacy Regulations

We are subject to various 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), 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.   

22

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. This Omnibus rule enhances the privacy protections and strengthens the government's ability to enforce the law. 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 are subject to the requirements under the Payment Card Industry (PCI) 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.

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 participants in public government healthcare programs such as Medicare and Medicaid. 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 waste, fraud 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, 2016, we had approximately 30,500 employees. None of our employees are represented by a union. We believe our relationships with our employees are positive.

ITEM 1A. Risk Factors

FACTORS THAT MAY AFFECT FUTURE RESULTS AND THE

TRADING PRICE OF OUR COMMON STOCK

You should carefully consider the risks described below before making an investment decision. The trading price of our common stock could decline due to any of these risks, in which case you could lose all or part of your investment. You should also refer to the other information in this filing, including our consolidated financial statements and related notes. The risks and uncertainties described below are those that we currently believe may materially affect our Company. Additional risks and uncertainties that we are unaware of or that we currently deem immaterial also may become important factors that affect our Company.

Reductions in funding, changes to eligibility requirements for government sponsored healthcare programs in which we participate and any inability on our part to effectively adapt to changes to these programs could substantially affect our financial position, results of operations and cash flows.

The majority of our revenues come from government subsidized healthcare programs including Medicaid, Medicare, TRICARE, VA, CHIP, LTC, ABD, Foster Care and Health Insurance Marketplace premiums. Under most programs, the base premium rate paid for each program differs, depending on a combination of factors such as defined upper payment limits, a member’s health status, age, gender, county or region and benefit mix. Since Medicaid was created in 1965, the federal government and the states have shared the costs for this program, with the federal share currently averaging around 57%. We are therefore exposed to risks associated with U.S. and state government contracting or participating in programs involving a government payor, including but not limited to the general ability of the federal and/or state government to terminate contracts with it, in whole or in part, without prior notice, for convenience or for default based on performance; potential regulatory or legislative action that may materially modify amounts owed; and our dependence upon Congressional or legislative appropriation and allotment of funds and the impact that delays in government payments could have on our operating cash flow and liquidity. For example, future levels of funding and premium rates may be affected by continuing government efforts to contain healthcare costs and may further be affected by state and federal budgetary constraints. Governments periodically consider reducing or reallocating the amount of money they spend for Medicaid, Medicare, TRICARE, VA, CHIP, LTC, ABD and Foster Care. Furthermore, Medicare remains subject to the automatic spending reductions imposed by the Budget Control Act of 2011 and the American Taxpayer Relief Act of 2012 (“sequestration”), subject to a 2% cap. In addition, reductions in defense spending could have an adverse impact on certain government programs in which we currently participate by, among other things, terminating or materially changing such programs, or by decreasing or delaying payments made under such programs. Adverse economic conditions may continue to put pressures on state budgets as tax and other state revenues decrease while the population that is eligible to participate in these programs increases, creating more need for funding. We anticipate this will require government agencies to find funding alternatives, which may result in reductions in funding for programs, contraction of covered benefits, and limited or no premium rate increases or premium rate decreases. A reduction (or less than expected increase), a protracted delay, or a change in allocation methodology in government funding for these programs, as well as termination of the contract for the convenience of the government, may materially and adversely affect our results of operations, financial position and cash flows. In addition, if a federal government shutdown were to occur for a prolonged period of time, federal government payment obligations, including its obligations under Medicaid, Medicare, TRICARE, VA, CHIP, LTC, ABD, Foster Care and the Health Insurance Marketplaces, may be delayed. Similarly, if state government shutdowns were to occur, state payment obligations may be delayed. If the federal or state governments fail to make payments under these programs on a timely basis, our business could suffer, and our financial position, results of operations or cash flows may be materially affected.

There can be no assurance that we will avoid payment delays from government payors in the future, which, if extended for any significant period of time, could have a material adverse effect on our results of operations, financial position, cash flows or liquidity. In addition, delays in obtaining, or failure to obtain or maintain, governmental approvals, or moratoria imposed by regulatory authorities, could adversely affect our revenue or membership, increase costs or adversely affect our ability to bring new products to market as forecasted. Other changes to our government programs could affect our willingness or ability to participate in any of these programs or otherwise have a material adverse effect on our business, financial condition or results of operations.

25

Finally, changes in these programs could reduce the number of persons enrolled in or eligible for these programs or increase our administrative or healthcare costs under these programs. For example, recent legislation generally requires that eligibility levels be maintained, but this could cause states to reduce reimbursement or reduce benefits in order for states to afford to maintain eligibility levels. If any state in which we operate were to decrease premiums paid to us or pay us less than the amount necessary to keep pace with our cost trends, it could have a material adverse effect on our results of operations, financial position and cash flows.

Our Medicare programs are subject to a variety of risks that could adversely impact our financial results.

If we fail to design and maintain programs that are attractive to Medicare participants; if our Medicare operations are subject to program audits, sanctions or penalties; if we do not submit adequate bids in our existing markets or any expansion markets; if our existing contracts are terminated; or if we fail to maintain or improve our star ratings, our current Medicare business and our ability to expand our Medicare operations could be materially and adversely affected, negatively impacting our financial performance. There are also specific additional risks under Title XVIII, Part D of the Social Security Act associated with our provision of Medicare Part D prescription drug benefits as part of our Medicare Advantage plan offerings. These risks include potential uncollectibility of receivables, inadequacy of pricing assumptions, inability to receive and process information and increased pharmaceutical costs, as well as the underlying seasonality of this business, and extended settlement periods for claims submissions. Our failure to comply with Part D program requirements can result in financial and/or operational sanctions on our Part D products, as well as on our Medicare Advantage products that offer no prescription drug coverage.

Failure to accurately estimate and price our medical expenses or effectively manage our medical costs or related administrative costs could negatively affect our financial position, results of operations or cash flows.

Our profitability, to a significant degree, depends on our ability to estimate and effectively manage expenses related to health benefits through, among other things, our ability to contract favorably with hospitals, physicians and other healthcare providers. For example, our Medicaid revenue is often based on bids submitted before the start of the initial contract year. If our actual medical expense exceeds our estimates, our health benefits ratio (HBR), or our expenses related to medical services as a percentage of premium revenue, would increase and our profits would decline. Because of the narrow margins of our health plan business, relatively small changes in our HBR can create significant changes in our financial results. Changes in healthcare regulations and practices, the level of utilization of healthcare services, hospital and pharmaceutical costs, disasters, the potential effects of climate change, major epidemics, pandemics or newly emergent viruses, including the Zika virus, new medical technologies, new pharmaceutical compounds, increases in provider fraud and other external factors, including general economic conditions such as inflation and unemployment levels, are generally beyond our control and could reduce our ability to accurately predict and effectively control the costs of providing health benefits. In addition, the 2017 marketplace for individual products may be less stable than in 2016 because, among other things, other health plans have changed or stopped offering their Health Insurance Marketplace products in the states we expect to serve in 2017. Also, member behavior could be influenced by uncertainty of potential changes to the Patient Protection and Affordable Care Act and the accompanying Health Care and Education Affordability Reconciliation Act, collectively referred to as the Affordable Care Act (ACA).

Our medical expense includes claims reported but not paid, estimates for claims incurred but not reported, and estimates for the costs necessary to process unpaid claims at the end of each period. Our development of the medical claims liability estimate is a continuous process which we monitor and refine on a monthly basis as claims receipts and payment information as well as inpatient acuity information becomes available. As more complete information becomes available, we adjust the amount of the estimate, and include the changes in estimates in medical expense in the period in which the changes are identified. Given the uncertainties inherent in such estimates, there can be no assurance that our medical claims liability estimate will be adequate, and any adjustments to the estimate may unfavorably impact our results of operations and may be material.

Additionally, when we commence operations in a new state, region or product, we have limited information with which to estimate our medical claims liability. For a period of time after the inception of the new business, we base our estimates on government-provided historical actuarial data and limited actual incurred and received claims and inpatient acuity information. The addition of new categories of eligible individuals as well as evolving Health Insurance Marketplace plans may pose difficulty in estimating our medical claims liability.

From time to time in the past, our actual results have varied from our estimates, particularly in times of significant changes in the number of our members. If it is determined that our estimates are significantly different than actual results, our results of operations and financial position could be adversely affected. In addition, if there is a significant delay in our receipt of premiums, our business operations, cash flows, or earnings could be negatively impacted.

26

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.

In March 2010, ACA was enacted. While the constitutionality of the ACA was generally upheld by the Supreme Court in 2012, the Court determined that states could elect to opt out of the Medicaid expansion portion of ACA without losing all federal money for their existing Medicaid programs.

Under the 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 each states' election. The federal government pays the entire costs for Medicaid coverage for newly eligible beneficiaries for three years (2014 through 2016). Beginning in 2017, the federal share begins to decline, ending at 90% for 2020 and subsequent years. As of December 31, 2016, 31 states and the District of Columbia have expanded Medicaid eligibility, and additional states continue to discuss expansion. The ACA also maintained CHIP eligibility standards through September 2019.

The ACA required the establishment of Health Insurance Marketplaces for individuals and small employers to purchase health insurance coverage commencing in January 2014. The ACA required insurers participating on the Health Insurance Marketplaces to offer a minimum level of benefits and included guidelines on setting premium rates and coverage limitations.

Any failure to adequately price products offered in the Health Insurance Marketplaces may have a negative impact on our results of operations, financial position and cash flow. Among other things, we may be adversely selected by individuals who have a higher acuity level than the anticipated pool of participants. In addition, the risk corridor, reinsurance and risk adjustment ("three Rs") provisions of the ACA established to apportion risk amongst insurers may not be effective in appropriately mitigating the financial risks related to the Marketplace product. Further, the three Rs may not be adequately funded. Moreover, changes in the competitive marketplace over time may exacerbate the uncertainty in these relatively new markets. For example, competitors seeking to gain a foothold in the changing market may introduce pricing that we may not be able to match, which may adversely affect our ability to compete effectively. Competitors may also choose to exit the market altogether or otherwise suffer financial difficulty, which could adversely impact the pool of potential insured, require us to increase premium rates or result in funding issues under the three Rs. These potential exits and other continued volatility in this market may be further exacerbated by the conclusion of the risk corridor and reinsurance programs as of January 1, 2017. Our continued success in the exchanges is dependent on our ability to successfully respond to these changes in the market over time. Any significant variation from our expectations regarding acuity, enrollment levels, adverse selection, the three Rs, or other assumptions utilized in setting adequate premium rates could have a material adverse effect on our results of operations, financial position and cash flows.

The U.S. Department of Health and Human Services (HHS) has stated that it will consider a limited number of premium assistance demonstration proposals from States that want to privatize Medicaid expansion. States must provide a choice between at least two qualified health plans and offer very similar benefits as those available in the Health Insurance Marketplaces. Arkansas became the first state to obtain federal approval to use Medicaid funding to purchase private insurance for low-income residents and we began operations under the program beginning January 1, 2014.

The ACA imposed an annual insurance industry assessment of $8.0 billion in 2014, and $11.3 billion in each of 2015 and 2016, with increasing annual amounts thereafter. Such assessments are not deductible for federal and most state income tax purposes. The fee is allocated based on health insurers' premium revenues in the previous year. Each health insurer's fee is calculated by multiplying its market share by the annual fee. Market share is based on commercial, Medicare, and Medicaid premium revenue. Not-for-profit insurers may have a competitive advantage since they are exempt from paying the fee if they receive at least 80% of their premium revenue from Medicare, Medicaid, and CHIP, and other not-for-profit insurers are allowed to exclude 50% of their premium revenue from the fee calculation. The health insurer fee payable in 2017 was suspended by the Consolidated Appropriations Act for fiscal year 2016. If we are not reimbursed by the states for the cost of the federal premium assessment (including the associated tax impact), or if we are unable to otherwise adjust our business model to address this new assessment, our results of operations, financial position and cash flows may be materially adversely affected.

There are numerous steps required to implement the ACA, including the promulgation of a substantial number of new and potentially more onerous federal regulations. For example, in April 2016, CMS issued final regulations that revised existing Medicaid managed care rules by establishing a minimum MLR standard for Medicaid of 85% and strengthening provisions related to network adequacy and access to care, enrollment and disenrollment protections, beneficiary support information, continued service during beneficiary appeals, and delivery system and payment reform initiatives, among others. If we fail to effectively implement or appropriately adjust our operational and strategic initiatives with respect to the implementation of healthcare reform, or do not do so as effectively as our competitors, our results of operations may be materially adversely affected.

27

In addition, the U.S. Court of Appeals for the D.C. circuit has granted a motion to put a lawsuit challenging the ACA’s cost-sharing subsidies on hold until the new administration takes over. Now that the U.S. Court of Appeals has stayed the case, the new administration and Congress will decide how they want to proceed, including whether to seek policy changes such as ACA repeal or replacement that affect the issues under review in this case.

Changes to, or repeal of, the ACA, which the new administration and certain members of Congress have affirmatively indicated that they will pursue, could materially and adversely affect our business and financial position, results of operations or cash flows. Even if the ACA is not amended or repealed, the new administration could propose changes impacting implementation of the ACA, which could materially and adversely affect our financial position or operations. However, the ultimate content, timing or effect of any potential future legislation enacted under the new administration cannot be predicted.

Our business activities are highly regulated and new laws or regulations or changes in existing laws or regulations or their enforcement or application could force us to change how we operate and could harm our business.

Our business is extensively regulated by the states in which we operate and by the federal government. In addition, the managed care industry has received negative publicity that has led to increased legislation, regulation, review of industry practices and private litigation in the commercial sector. Such negative publicity may adversely affect our stock price and damage our reputation in various markets.

In each of the jurisdictions in which we operate, we are regulated by the relevant insurance, health and/or human services or government departments that oversee the activities of managed care organizations providing or arranging to provide services to Medicaid, Medicare, Health Insurance Marketplace enrollees or other beneficiaries. For example, 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.

The frequent enactment of, changes to, or interpretations of laws and regulations could, among other things: force us to restructure our relationships with providers within our network; require us to implement additional or different programs and systems; restrict revenue and enrollment growth; increase our healthcare and administrative costs; impose additional capital and surplus requirements; and increase or change our liability to members in the event of malpractice by our contracted providers. In addition, changes in political party or administrations at the state, federal or country level may change the attitude towards healthcare programs and result in changes to the existing legislative or regulatory environment.

Additionally, the taxes and fees paid to federal, state and local governments may increase due to several factors, including:  enactment of, changes to, or interpretations of tax laws and regulations, audits by governmental authorities, geographic expansions into higher taxing jurisdictions and the effect of expansions into international markets.

Our contracts with states may require us to maintain a minimum HBR or may require us to share profits in excess of certain levels. In certain circumstances, our plans may be required to return premium back to the state in the event profits exceed established levels or HBR does not meet the minimum requirement. Other states may require us to meet certain performance and quality metrics in order to maintain our contract or receive additional or full contractual revenue.

The governmental healthcare programs in which we participate are subject to the satisfaction of certain regulations and performance standards. For example, under Health Reform Legislation, Congress authorized CMS and the states to implement managed care demonstration programs to serve dually eligible beneficiaries to improve the coordination of their care. Participation in these demonstration programs is subject to CMS approval and the satisfaction of conditions to participation, including meeting certain performance requirements. Our inability to improve or maintain adequate 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. Specifically, several of our Medicaid contracts require us to maintain a Medicare health plan. Although we strive to comply with all existing regulations and to meet performance standards applicable to our business, failure to meet these requirements could result in financial fines and penalties. Also, states or other governmental entities may not allow us to continue to participate in their government programs, or we may fail to win procurements to participate in such programs which could materially and adversely affect our results of operations, financial position and cash flows.

28

In addition, as a result of the expansion of our businesses and operations conducted in foreign countries, we face political, economic, legal, compliance, regulatory, operational and other risks and exposures that are unique and vary by jurisdiction. These foreign regulatory requirements with respect to, among other items, environmental, tax, licensing, intellectual property, privacy, data protection, investment, capital, management control, labor relations, and fraud and corruption regulations are different than those faced by our domestic businesses. In addition, we 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. Our failure to comply with laws and regulations governing our conduct outside the United States or to successfully navigate international regulatory regimes that apply to us could adversely affect our ability to market our products and services, which may have a material adverse effect on our business, financial condition and results of operations.

Our businesses providing pharmacy benefit management (PBM) and specialty pharmacy services face regulatory and other risks and uncertainties which could materially and adversely affect our results of operations, financial position and cash flows.

We provide PBM and specialty pharmacy services, including through our Envolve Pharmacy Solutions product. These businesses are subject to federal and state laws that govern the relationships of the business with pharmaceutical manufacturers, physicians, pharmacies, customers and consumers. We also conduct business as a mail order pharmacy and specialty pharmacy, which subjects these businesses to extensive federal, state and local laws and regulations. In addition, federal and state legislatures regularly consider new regulations for the industry that could materially and adversely affect current industry practices, including the receipt or disclosure of rebates from pharmaceutical companies, the development and use of formularies, and the use of average wholesale prices.

Our PBM and specialty pharmacy businesses would be materially and adversely affected by an inability to contract on favorable terms with pharmaceutical manufacturers and other suppliers, including with respect to the pricing of new specialty and generic drugs. In addition, our PBM and specialty pharmacy businesses could face potential claims in connection with purported errors by our mail order or specialty pharmacies, including in connection with the risks inherent in the authorization, compounding, packaging and distribution of pharmaceuticals and other healthcare products. Disruptions at any of our mail order or specialty pharmacies due to an event that is beyond our control could affect our ability to process and dispense prescriptions in a timely manner and could materially and adversely affect our results of operations, financial position and cash flows.

If any of our government contracts are terminated or are not renewed on favorable terms or at all, or if we receive an adverse finding or review resulting from an audit or investigation, our business may be adversely affected.

A substantial portion of our business relates to the provision of managed care programs and selected services to individuals receiving benefits under governmental assistance or entitlement programs. We provide these and other healthcare services under contracts with government entities in the areas in which we operate. Our government contracts are generally intended to run for a fixed number of years and may be extended for additional specified number of years if the contracting entity or its agent elects to do so. When our contracts with the government expire, they may be opened for bidding by competing healthcare providers, and there is no guarantee that our contracts will be renewed or extended. Competitors may buy their way into the market by submitting bids with lower pricing. Even if our responsive bids are successful, the bids may be based upon assumptions or other factors which could result in the contracts being less profitable than we had anticipated. Further, our government contracts contain certain provisions regarding eligibility, enrollment and dis-enrollment processes for covered services, eligible providers, periodic financial and informational reporting, quality assurance, timeliness of claims payment and agreement to maintain a Medicare plan in the state and financial standards, among other things, and are subject to cancellation if we fail to perform in accordance with the standards set by regulatory agencies.

We are also subject to various reviews, audits and investigations to verify our compliance with the terms of our contracts with various governmental agencies, as well as compliance with applicable laws and regulations. Any adverse review, audit or investigation could result in, among other things: cancellation of our contracts; refunding of amounts we have been paid pursuant to our contracts; imposition of fines, penalties and other sanctions on us; loss of our right to participate in various programs; increased difficulty in selling our products and services; loss of one or more of our licenses; or require changes to the way we do business. In addition, under government procurement regulations and practices, a negative determination resulting from a government audit of our business practices could result in a contractor being fined, debarred and/or suspended from being able to bid on, or be awarded, new government contracts for a period of time.

29

If any of our government contracts are terminated, not renewed, renewed on less favorable terms, or not renewed on a timely basis, or if we receive an adverse finding or review resulting from an audit or investigation, our business and reputation may be adversely impacted, our goodwill could be impaired and our financial position, results of operations or cash flows may be materially affected.

We contract with independent third party vendors and service providers who provide services to us and our subsidiaries or to whom we delegate selected functions. Violations of, or noncompliance with, laws and regulations governing our business by such third parties, or governing our dealings with such parties, could, among other things, subject us to additional audits, reviews and investigations and other adverse effects.

Ineffectiveness of state-operated systems and subcontractors could adversely affect our business.

A number of our health plans rely on other state-operated systems or subcontractors to qualify, solicit, educate and assign eligible members into managed care plans. The effectiveness of these state operations and subcontractors can have a material effect on a health plan’s enrollment in a particular month or over an extended period. When a state implements new programs to determine eligibility, new processes to assign or enroll eligible members into health plans, or chooses new subcontractors, there is an increased potential for an unanticipated impact on the overall number of members assigned to managed care plans.

Our investment portfolio may suffer losses which could materially and adversely affect our results of operations or liquidity.

We maintain a significant investment portfolio of cash equivalents and short term and long term investments in a variety of securities, which are subject to general credit, liquidity, market and interest rate risks and will decline in value if interest rates increase or one of the issuers’ credit ratings is reduced. As a result, we may experience a reduction in value or loss of our investments, which may have a negative adverse effect on our results of operations, liquidity and financial condition.

Execution of our growth strategy may increase costs or liabilities, or create disruptions in our business.

Our growth strategy includes, without limitation, the acquisition of health plans participating in government sponsored healthcare programs and specialty services businesses, contract rights and related assets of other health plans both in our existing service areas and in new markets and start-up operations in new markets or new products in existing markets. Although we review the records of companies or businesses we plan to acquire, it is possible that we could assume unanticipated liabilities or adverse operating conditions, or an acquisition may not perform as well as expected or may not achieve timely profitability. We also face the risk that we will not be able to effectively integrate acquisitions into our existing operations effectively without substantial expense, delay or other operational or financial problems and we may need to divert more management resources to integration than we planned.

In connection with start-up operations, we may incur significant expenses prior to commencement of operations and the receipt of revenue. For example, in order to obtain a certificate of authority in most jurisdictions, we must first establish a provider network, have systems in place and demonstrate our ability to administer a state contract and process claims. We may experience delays in operational start dates. As a result of these factors, start-up operations may decrease our profitability. In addition, we are planning to expand our business internationally and we will be subject to additional risks, including, but not limited to, political risk, an unfamiliar regulatory regime, currency exchange risk and exchange controls, cultural and language differences, foreign tax issues, and different labor laws and practices.

If we are unable to effectively execute our growth strategy, our future growth will suffer and our results of operations could be harmed.

If competing managed care programs are unwilling to purchase specialty services from us, we may not be able to successfully implement our strategy of diversifying our business lines.

We are seeking to diversify our business lines into areas that complement our government sponsored health plan business in order to grow our revenue stream and balance our dependence on risk reimbursement. In order to diversify our business, we must succeed in selling the services of our specialty subsidiaries not only to our managed care plans, but to programs operated by third-parties. Some of these third-party programs may compete with us in some markets, and they therefore may be unwilling to purchase specialty services from us. In any event, the offering of these services will require marketing activities that differ significantly from the manner in which we seek to increase revenues from our government sponsored programs. Our ineffectiveness in marketing specialty services to third-parties may impair our ability to execute our business strategy.

30

Adverse credit market conditions may have a material adverse effect on our liquidity or our ability to obtain credit on acceptable terms.

In the past, the securities and credit markets have experienced extreme volatility and disruption. The availability of credit, from virtually all types of lenders, has at times been restricted. In the event we need access to additional capital to pay our operating expenses, fund subsidiary surplus requirements, make payments on or refinance our indebtedness, pay capital expenditures, or fund acquisitions, our ability to obtain such capital may be limited and the cost of any such capital may be significant, particularly if we are unable to access our existing credit facility.

Our access to additional financing will depend on a variety of factors such as prevailing economic and credit market conditions, the general availability of credit, the overall availability of credit to our industry, our credit ratings and credit capacity, and perceptions of our financial prospects. Similarly, our access to funds may be impaired if regulatory authorities or rating agencies take negative actions against us. If a combination of these factors were to occur, our internal sources of liquidity may prove to be insufficient, and in such case, we may not be able to successfully obtain sufficient additional financing on favorable terms, within an acceptable time, or at all.

If state regulators do not approve payments of dividends and distributions by our subsidiaries to us, we may not have sufficient funds to implement our business strategy.

We principally operate through our health plan subsidiaries. As part of normal operations, we may make requests for dividends and distributions from our subsidiaries to fund our operations. These subsidiaries are subject to regulations that limit the amount of dividends and distributions that can be paid to us without prior approval of, or notification to, state regulators. If these regulators were to deny our subsidiaries’ request to pay dividends, the funds available to us would be limited, which could harm our ability to implement our business strategy.

We derive a majority of our premium revenues from operations in a limited number of states, and our financial position, results of operations or cash flows would be materially affected by a decrease in premium revenues or profitability in any one of those states.

Operations in a limited number of states have accounted for most of our premium revenues to date. If we were unable to continue to operate in any of those states or if our current operations in any portion of one of those states were significantly curtailed, our revenues could decrease materially. Our reliance on operations in a limited number of states could cause our revenue and profitability to change suddenly and unexpectedly depending on legislative or other governmental or regulatory actions and decisions, economic conditions and similar factors in those states. For example, states we currently serve may open the bidding for their Medicaid program to other health insurers through a request for proposal process. Our inability to continue to operate in any of the states in which we operate could harm our business.

Competition may limit our ability to increase penetration of the markets that we serve.

We compete for members principally on the basis of size and quality of provider networks, benefits provided and quality of service. We compete with numerous types of competitors, including other health plans and traditional state Medicaid programs that reimburse providers as care is provided, among others. In addition, the impact of healthcare reform legislation and potential growth in our segment may attract new competitors.

Some of the health plans with which we compete have greater financial and other resources and offer a broader scope of products than we do. In addition, significant merger and acquisition activity has occurred in the managed care industry, as well as complementary industries, such as the hospital, physician, pharmaceutical, medical device and health information systems businesses. To the extent that competition intensifies in any market that we serve, as a result of industry consolidation or otherwise, our ability to retain or increase members and providers, or maintain or increase our revenue growth, pricing flexibility and control over medical cost trends may be adversely affected.

31

If we are unable to maintain relationships with our provider networks, our profitability may be harmed.

Our profitability depends, in large part, upon our ability to contract at competitive prices with hospitals, physicians and other healthcare providers. Our provider arrangements with our primary care physicians, specialists and hospitals generally may be canceled by either party without cause upon 90 to 120 days prior written notice. We cannot provide any assurance that we will be able to continue to renew our existing contracts or enter into new contracts on a timely basis or under favorable terms enabling us to service our members profitably. Healthcare providers with whom we contract may not properly manage the costs of services, maintain financial solvency or avoid disputes with other providers. Any of these events could have a material adverse effect on the provision of services to our members and our operations.

In any particular market, physicians and other healthcare providers could refuse to contract, demand higher payments, or take other actions that could result in higher medical costs or difficulty in meeting regulatory or accreditation requirements, among other things. In some markets, certain healthcare 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 marketing leverage, and other organizational structures that physicians, hospitals and other healthcare providers choose may change the way in which these providers interact with us and may change the competitive landscape. Such organizations or groups of healthcare providers 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 operations. Provider networks may consolidate, resulting in a reduction in the competitive environment. In addition, if these providers refuse to contract with us, use their market position to negotiate contracts unfavorable to us 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.

From time to time healthcare providers assert or threaten to assert claims seeking to terminate non-cancelable agreements due to alleged actions or inactions by us. If we are unable to retain our current provider contract terms or enter into new provider contracts timely or on favorable terms, our profitability may be harmed. In addition, from time to time, we may be subject to class action or other lawsuits by healthcare providers with respect to claim payment procedures or similar matters. For example, the Company’s wholly owned subsidiary, Health Net Life Insurance Company (“HNL”), is and may continue to be subject to such disputes with respect to HNL’s payment levels in connection with the processing of out-of-network provider reimbursement claims for the provision of certain substance abuse related services. HNL expects to vigorously defend its claims payment practices. Nevertheless, in the event HNL receives an adverse finding in any related legal proceeding or from a regulator, or is otherwise required to reimburse providers for these claims at rates that are higher than expected or for claims HNL otherwise believes are unallowable, the Company’s financial condition and results of operations may be materially adversely affected. In addition, regardless of whether any such lawsuits brought against us are successful or have merit, they will still be time-consuming and costly and could distract our management’s attention. As a result, under such circumstances we may incur significant expenses and may be unable to operate our business effectively.

We may be unable to attract, retain or effectively manage the succession of key personnel.

We are highly dependent on our ability to attract and retain qualified personnel to operate and expand our business. We would be adversely impacted if we are unable to adequately plan for the succession of our executives and senior management. While we have succession plans in place for members of our executive and senior management team, these plans do not guarantee that the services of our executive and senior management team will continue to be available to us. Our ability to replace any departed members of our executive and senior management or other key employees may be difficult and may take an extended period of time because of the limited number of individuals in the managed care and specialty services industry with the breadth of skills and experience required to operate and successfully expand a business such as ours. Competition to hire from this limited pool is intense, and we may be unable to hire, train, retain or motivate these personnel. If we are unable to attract, retain and effectively manage the succession plans for key personnel, executives and senior management, our business and financial position, results of operations or cash flows could be harmed.

32

If we are unable to integrate and manage our information systems effectively, our operations could be disrupted.

Our operations depend significantly on effective information systems. The information gathered and processed by our information systems assists us in, among other things, monitoring utilization and other cost factors, processing provider claims, and providing data to our regulators. Our healthcare providers also depend upon our information systems for membership verifications, claims status and other information. Our information systems and applications require continual maintenance, upgrading and enhancement to meet our operational needs and regulatory requirements. We regularly upgrade and expand our information systems’ capabilities. If we experience difficulties with the transition to or from information systems or do not appropriately integrate, maintain, enhance or expand our information systems, we could suffer, among other things, operational disruptions, loss of existing members and difficulty in attracting new members, regulatory problems and increases in administrative expenses. In addition, our ability to integrate and manage our information systems may be impaired as the result of events outside our control, including acts of nature, such as earthquakes or fires, or acts of terrorists.

From time to time, we may become involved in costly and time-consuming litigation and other regulatory proceedings, which require significant attention from our management.

From time to time we are a defendant in lawsuits and regulatory actions and are subject to investigations relating to our business, including, without limitation, medical malpractice claims, claims by members alleging failure to pay for or provide health care, claims related to non-payment or insufficient payments for out-of-network services, claims alleging bad faith, investigations regarding our submission of risk adjuster claims, putative securities class actions, and claims related to the imposition of new taxes, including but not limited to claims that may have retroactive application. Due to the inherent uncertainties of litigation and regulatory proceedings, we cannot accurately predict the ultimate outcome of any such proceedings. An unfavorable outcome could have a material adverse impact on our business and financial position, results of operations and/or cash flows and may affect our reputation. In addition, regardless of the outcome of any litigation or regulatory proceedings, such proceedings are costly and time consuming and require significant attention from our management, and could therefore harm our business and financial position, results of operations or cash flows.

An impairment charge with respect to our recorded goodwill and intangible assets could have a material impact on our results of operations.

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. Changes in business strategy, government regulations or economic or market conditions have resulted and may result in impairments of our goodwill and other intangible assets at any time in the future. Our judgments regarding the existence of impairment indicators are based on, among other things, legal factors, market conditions, and operational performance. For example, the non-renewal of our health plan contracts with the state in which they operate may be an indicator of impairment. If an event or events occur that would cause us to revise our estimates and assumptions used in analyzing the value of our goodwill and other intangible assets, such revision could result in a non-cash impairment charge that could have a material impact on our results of operations in the period in which the impairment occurs.

33

If we fail to comply with applicable privacy, security, and data laws, regulations and standards, including with respect to third-party service providers that utilize sensitive personal information on our behalf, our business, reputation, results of operations, financial position and cash flows could be materially and adversely affected.

As part of our normal operations, we collect, process and retain confidential member information. We are subject to various federal and state laws and rules regarding the use and disclosure of confidential member information, including the Health Insurance Portability and Accountability Act of 1996 (HIPAA) and the Health Information Technology for Economic and Clinical Health (HITECH) Act of 2009 and the Gramm-Leach-Bliley Act, which require us to protect the privacy of medical records and safeguard personal health information we maintain and use. Certain 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. Despite our best attempts to maintain adherence to information privacy and security best practices as well as compliance with applicable laws, rules and contractual requirements, our facilities and systems, and those of our third party service providers, may be vulnerable to privacy or security breaches, acts of vandalism or theft, malware or other forms of cyber attack, misplaced or lost data including paper or electronic media, programming and/or human errors or other similar events. In the past, we have had data breaches resulting in disclosure of confidential or protected health information that have not resulted in any material financial loss or penalty to date. However, future data breaches could require us to expend significant resources to remediate any damage, interrupt our operations and damage our reputation, subject us to state or federal agency review and could also result in enforcement actions, material fines and penalties, litigation or other actions which could have a material adverse effect on our business, reputation and results of operations, financial position and cash flows.

In addition, HIPAA broadened the scope of fraud and abuse laws applicable to healthcare companies.  HIPAA established new enforcement mechanisms to combat fraud and abuse, including civil and, in some instances, criminal penalties for failure to comply with specific standards relating to the privacy, security and electronic transmission of protected health information. The HITECH Act expanded the scope of these provisions by mandating individual notification in instances of breaches of protected health information, providing enhanced penalties for HIPAA violations, and granting enforcement authority to states’ Attorneys General in addition to the HHS Office for Civil Rights.  It is possible that Congress may enact additional legislation in the future to increase penalties and to create a private right of action under HIPAA, which could entitle patients to seek monetary damages for violations of the privacy rules. Additionally, HHS continued its auditing program in 2016 to assess compliance efforts by covered entities and business associates. Through a second phase of audits, which commenced for covered entities in July 2016, HHS focused on a review of policies and procedures adopted and employed by covered entities and their business associates to meet selected standards and implementation specifications of the HIPAA Privacy, Security, and Breach Notification Rules. 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.

If we fail to comply with the extensive federal and state fraud and abuse laws, our business, reputation, results of operations, financial position and cash flows could be materially and adversely affected.

We, along with all other companies involved in public health care programs are the subject of fraud and abuse investigations from time to time. The regulations and contractual requirements applicable to participants in these public sector programs are complex and subject to change. Violations of fraud and abuse laws applicable to us could result in civil monetary penalties, criminal fines and imprisonment, and/or exclusion from participation in Medicaid, Medicare, TRICARE, VA and other federal health care programs and federally funded state health programs. Fraud and abuse prohibitions encompass a wide range of activities, including kickbacks for referral of members, billing for unnecessary medical services, improper marketing and violations of patient privacy rights. These fraud 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. In addition, the Deficit Reduction Act of 2005 encouraged states to enact state-versions of the federal False Claims Act that establish liability to the state for false and fraudulent Medicaid claims and that provide for, among other things, claims to be filed by qui tam relators. Federal and state governments have made investigating and prosecuting health care fraud and abuse a priority. In the event we fail to comply with the extensive federal and state fraud and abuse laws, our business, reputation, results of operations, financial position and cash flows could be materially and adversely affected.

34

A failure in or breach of our operational or security systems or infrastructure, or those of third parties with which we do business, including as a result of cyber attacks, could have an adverse effect on our business.

Information security risks have significantly increased in recent years in part because of the proliferation of new technologies, the use of the internet and telecommunications technologies to conduct our operations, and the increased sophistication and activities of organized crime, hackers, terrorists and other external parties, including foreign state agents. Our operations rely on the secure processing, transmission and storage of confidential, proprietary and other information in our computer systems and networks.

Security breaches may arise from external or internal threats. External breaches include hacking personal information for financial gain, attempting to cause harm or interruption to our operations, or intending to obtain competitive information. We experience attempted external hacking or malicious attacks on a regular basis. We maintain a rigorous system of preventive and detective controls through our security programs; however, our prevention and detection controls may not prevent or identify all such attacks on a timely basis, or at all. Internal breaches may result from inappropriate security access to confidential information by rogue employees, consultants or third party service providers. Any security breach involving the misappropriation, loss or other unauthorized disclosure or use of confidential member information, financial data, competitively sensitive information, or other proprietary data, whether by us or a third party, could have a material adverse effect on our business reputation, financial condition, cash flows, or results of operations.

We may be unable to successfully integrate our business with Health Net and realize the anticipated benefits of the acquisition.

We completed the acquisition of Health Net on March 24, 2016. The success of the acquisition of Health Net will depend, in part, on our ability to successfully combine the businesses of the Company and Health Net and realize the anticipated benefits, including synergies, cost savings, growth in earnings, innovation and operational efficiencies, from the combination. If we are unable to achieve these objectives within the anticipated time frame, or at all, the anticipated benefits may not be realized fully or at all, or may take longer to realize than expected and the value of our common stock may be harmed.

The integration of Health Net’s business with our existing business is a complex, costly and time-consuming process. We have not previously completed a transaction comparable in size or scope to the acquisition of Health Net. The integration of the two companies may result in material challenges, including, without limitation:

• the diversion of management’s attention from ongoing business concerns and performance shortfalls as a result of the devotion of management’s attention to the integration;

• managing a larger combined company;

• maintaining employee morale and retaining key management and other employees;

• the possibility of faulty assumptions underlying expectations regarding the integration process;

• retaining existing business and operational relationships and attracting new business and operational relationships;

• consolidating corporate and administrative infrastructures and eliminating duplicative operations;

• coordinating geographically separate organizations;

• unanticipated issues in integrating information technology, communications and other systems;

• unanticipated changes in federal or state laws or regulations, including the ACA and any regulations enacted thereunder; and

• unforeseen expenses or delays associated with the acquisition and/or integration.

Many of these factors will be outside of our control and any one of them could result in delays, increased costs, decreases in the amount of expected revenues and diversion of management’s time and energy, which could materially affect our financial position, results of operations and cash flows.

35

We have incurred substantial expenses related to the completion of the acquisition of Health Net and are incurring substantial expenses related to the integration of Health Net.

We are in the process of integrating a large number of processes, policies, procedures, operations, technologies and systems, including purchasing, accounting and finance, sales, payroll, pricing, revenue management, marketing and benefits, among other things. In addition, the businesses of Centene and Health Net will continue to maintain a presence in St. Louis, Missouri and Woodland Hills, California, respectively. The substantial majority of these costs will be non-recurring expenses related to the acquisition (including financing of the acquisition), facilities and systems consolidation costs. We may incur additional costs to maintain employee morale and to retain key employees. We are also incurring transaction fees and costs related to formulating integration plans for the combined business, and the execution of these plans may lead to additional unanticipated costs. These incremental transaction and acquisition-related costs may exceed the savings we expect to achieve from the elimination of duplicative costs and the realization of other efficiencies related to the integration of the businesses, particularly in the near term and in the event there are material unanticipated costs.

The market price of our common stock may decline as a result of the acquisition of Health Net.

The market price of our common stock is generally subject to volatility, and there can be no assurances regarding the level or stability of our share price at any time. The market price of our common stock may decline as a result of the acquisition if, among other things, we are unable to achieve the expected growth in earnings, or if the operational cost savings estimates in connection with the integration of Health Net’s business with ours are not realized, or if the transaction costs related to the acquisition and integration are greater than expected. The market price also may decline if we do not achieve the perceived benefits of the acquisition as rapidly or to the extent anticipated by financial or industry analysts or if the effect of the acquisition on our financial position, results of operations or cash flows is not consistent with the expectations of financial or industry analysts.

Our future results may be adversely impacted if we do not effectively manage our expanded operations following the completion of our acquisition of Health Net.

The size of our business following the acquisition of Health Net is significantly larger than the size of either Centene’s or Health Net’s respective businesses prior to the acquisition. Our ability to successfully manage the expanded business will depend, in part, upon management’s ability to design and implement strategic initiatives that address the increased scale and scope of the combined business with its associated increased costs and complexity. We will also have to manage our expanded operations in compliance with certain undertakings with regulators that were agreed to in connection with the approval of the acquisition. These undertakings require significant investments by us, may restrict or impose additional material costs on our future operations and strategic initiatives in certain geographies, and subject us to various enforcement mechanisms. There can be no assurances that we will be successful in managing our expanded operations or that we will realize the expected growth in earnings, operating efficiencies, cost savings and other benefits.

We are significantly more leveraged today than we have previously been.

As of December 31, 2016, we had consolidated indebtedness of approximately $4,655 million, which is significantly greater than the indebtedness that we have previously had. This increased indebtedness and higher debt-to-equity ratio will have the effect, among other things, of reducing our flexibility to respond to changing business and economic conditions and increasing borrowing costs.

Among other things, our revolving credit facility requires us to comply with various covenants that impose restrictions on our operations, including our ability to incur additional indebtedness, create liens, pay dividends, make investments or other restricted payments, sell or otherwise dispose of substantially all of our assets and engage in other activities. Our revolving credit facility also requires us to comply with a maximum leverage ratio and a minimum fixed charge coverage ratio. These restrictive covenants could limit our ability to pursue our business strategies. In addition, any failure by us to comply with these restrictive covenants could result in an event of default under the revolving credit facility and, in some circumstances, under the indentures governing our notes, which, in any case, could have a material adverse effect on our financial condition.

Item 1B. Unresolved Staff Comments

None.

Item 2. Properties

We own our corporate office headquarters buildings and land located in St. Louis, Missouri, which is used by each of our reportable segments. We generally lease space in the states where our health plans, specialty companies and claims processing facilities operate. We are required by various insurance and regulatory authorities to have offices in the service areas where we provide benefits. We believe our current facilities and expansion plans are adequate to meet our operational needs for the foreseeable future.

ITEM 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following discussion of our financial condition and results of operations should be read in conjunction with our consolidated financial statements and the related notes included elsewhere in this filing. The discussion contains forward-looking statements that involve known and unknown risks and uncertainties, including those set forth under Part I, Item 1A.“Risk Factors” of this Form 10-K.

EXECUTIVE OVERVIEW

General

We are a diversified, multi-national healthcare enterprise that provides services to government sponsored healthcare programs, focusing on under-insured and uninsured individuals. We provide member-focused services through locally based staff by assisting in accessing care, coordinating referrals to related health and social services and addressing member concerns and questions.

Results of operations depend on our ability to manage expenses associated with health benefits (including estimated costs incurred) and SG&A costs. We measure operating performance based upon two key ratios. The HBR represents medical costs as a percentage of premium revenues, excluding premium tax and health insurer fee revenues that are not separately billed, and reflects the direct relationship between the premium received and the medical services provided. The SG&A expense ratio represents SG&A costs as a percentage of premium and service revenues, again excluding premium tax and health insurer fee revenues that are not separately billed.

Health Net Acquisition

On March 24, 2016, the Company acquired all of the issued and outstanding shares of Health Net, a publicly traded managed care organization that delivers healthcare services through health plans and government-sponsored managed care plans. The transaction was valued at approximately $5,990 million, including the assumption of $703 million of outstanding debt. The acquisition allows the Company to offer a more comprehensive and scalable portfolio of solutions and provides opportunity for additional growth across the combined company's markets. 2016 was a transformative year with the acquisition of Health Net. Due to the size of this acquisition, the primary driver of the year over year variances discussed throughout this section are related to the acquisition of Health Net.

Regulatory Trends and Uncertainties

The new U.S. Presidential administration and certain members of Congress have affirmatively indicated that they will pursue full repeal of or significant amendment to the ACA. Even if the ACA is not amended or repealed, the new administration could propose changes impacting implementation of the ACA. The ultimate content and timing of any legislation enacted under the new administration that would impact the current implementation of the ACA remains uncertain. However, we believe we have both the capacity and capability to successfully navigate industry changes to the benefit of our members, customers and shareholders.

For additional information regarding regulatory trends and uncertainties, see Part I, Item 1 "Business - Regulation" and Item 1A, "Risk Factors."

2016 Highlights

Our financial performance for 2016 is summarized as follows:

• Year-end managed care membership of 11.4 million, an increase of over 6.3 million members, or 124% over 2015.

• Total revenues of $40.6 billion, representing 78% growth year over year.

• HBR of 86.5%, compared to 88.9% in 2015.

• SG&A expense ratio of 9.8% for 2016 compared to 8.5% for 2015. SG&A expense ratio excluding Health Net acquisition related expenses of 9.2% for 2016 compared to 8.3% for 2015.

42

• Operating cash flows of $1,851 million, or 3.3 times net earnings.

Year Ended December 31, 2016 Compared to Year Ended December 31, 2015

Total Revenues

Total revenues increased 78% in the year ended December 31, 2016, over the corresponding period in 2015, primarily as a result of the acquisition of Health Net, growth in the Health Insurance Marketplace business, and the impact from expansions, acquisitions or new programs in many of our states in 2016 and 2015. During the year ended December 31, 2016, we received Medicaid premium rate adjustments which yielded a net 1% composite change across all of our markets.

Operating Expenses

Medical Costs

The HBR for the year ended December 31, 2016 was 86.5%, a decrease of 240 basis points over the comparable period in 2015. The decrease compared to last year is primarily attributable to the acquisition of Health Net, membership growth in Medicaid expansion and Health Insurance Marketplace products, and improvement in HBR in the higher acuity populations. Also, in the fourth quarter, we recognized additional revenue relating to the retroactive contract amendment that changed the minimum MLR calculation under California's Medicaid expansion program, which reduced our 2016 HBR by 50 basis points.

Cost of Services

Cost of services increased by $243 million in the year ended December 31, 2016, compared to the corresponding period in 2015. This was primarily due to the acquisition of Health Net and growth in our correctional business, partially offset by lower pharmacy costs to external customers. The cost of service ratio for the year ended December 31, 2016 was 85.5%, compared to 86.4% in 2015. The decrease is primarily due to the acquisition of Health Net, which operates at a lower cost of service ratio.

Selling, General and Administrative Expenses

SG&A increased by $1,874 million in the year ended December 31, 2016, compared to the corresponding period in 2015.  This was primarily due to the acquisition of Health Net, acquisition related expenses, restructuring and integration costs, and the impact from expansions, acquisitions, or new programs in many of our states in 2016 and 2015. During the year ended December 31, 2016, we recorded approximately $234 million of Health Net acquisition related expenses, which reduced our diluted earnings per share by $0.98. During the year ended December 31, 2015, we recorded approximately $27 million of Health Net acquisition related expenses, which reduced our diluted earnings per share by $0.14. We also recorded expense of $50 million in 2016 for contribution commitments to our charitable foundation.

The consolidated SG&A expense ratio was 9.8% for the year ended December 31, 2016 compared to 8.5% for the year ended December 31, 2015. The consolidated SG&A expense ratio excluding Health Net acquisition related expenses was 9.2% for the year ended December 31, 2016 compared to 8.3% for the year ended December 31, 2015. The increase in the SG&A expense ratio is primarily attributable to the addition of the Health Net business, which operates at a higher SG&A expense ratio due to a higher mix of commercial and Medicare business.

Other Income (Expense)

The following table summarizes the components of other income (expense) for the year ended December 31, ($ in millions): 

	2016			2015
Investment income	$	109		$	27
Earnings from equity method investments	5			8
Interest expense	(217		)	(43		)
Other income (expense), net	$	(103	)	$	(8	)

49

The increase in investment income in 2016 reflects an increase in investment balances over 2015, primarily due to the acquisition of Health Net. Interest expense increased during the year ended December 31, 2016 by $174 million primarily reflecting the issuance of an additional $2,400 million in Senior Notes in February 2016 in connection with the financing of the Health Net transaction. Interest expense also increased due to the issuance of an additional $500 million in Senior Notes in June 2016, the assumption of Health Net's $400 million in Senior Notes, and the issuance of the $1,200 million in Senior Notes in November 2016. These increases were partially offset by the redemption of the Centene $425 million 5.75% Senior Notes and the Health Net $400 million 6.375% Senior Notes in November 2016 and December 2016, respectively. In addition, the Company incurred $11 million associated with the early redemption of the Centene 5.75% Senior Notes due 2017 and the Health Net 6.375% Senior Notes due 2017, which was recorded in Interest expense.

Income Tax Expense

Our effective tax rate for the year ended December 31, 2016 was 51.8% compared to 48.6% in 2015. The effective tax rate is higher than the applicable statutory rate primarily as a result of the non-deductibility of the HIF, limitations on the deductibility of compensation, and the non-deductibility of certain acquisition related costs incurred in connection with the acquisition of Health Net.

Segment Results

The following table summarizes our consolidated operating results by segment for the year ended December 31, ($ in millions):

	2016			2015			% Change 2015-2016
Total Revenues
Managed Care	$	37,722		$	20,644		83	%
Specialty Services	9,037			7,080			28	%
Eliminations	(6,152		)	(4,964		)	(24	)%
Consolidated Total	$	40,607		$	22,760		78	%
Earnings from Operations
Managed Care	$	1,070		$	513		109	%
Specialty Services	190			192			(1	)%
Consolidated Total	$	1,260		$	705		79	%

Managed Care

Total revenues increased 83% in the year ended December 31, 2016, compared to the year ended December 31, 2015, primarily as a result of the acquisition of Health Net and expansions or new programs in many of our states, particularly California, Florida, Georgia, Indiana, Louisiana, Mississippi, Oregon, Texas, and Washington. Earnings from operations increased $557 million between years primarily reflecting the acquisition of Health Net and product and geographical expansions in many of our states.

Specialty Services

Total revenues increased 28% in the year ended December 31, 2016, compared to the year ended December 31, 2015, resulting primarily from the acquisition of Health Net, growth in our behavioral health and correctional services businesses, and increased services associated with membership growth in the Managed Care segment. Earnings from operations decreased $2 million in the year ended December 31, 2016, compared to the year ended December 31, 2015, primarily due to lower earnings in our specialty pharmacy, home health, and behavioral health businesses as well as increased utilization in several specialty services businesses, partially offset by an increase in earnings related to our pharmacy benefits management and correctional services businesses, and the Health Net acquisition.

50

Year Ended December 31, 2015 Compared to Year Ended December 31, 2014

Total Revenues

Total revenues increased 37% in the year ended December 31, 2015, over the corresponding period in 2014, primarily as a result of the impact from expansions or new programs in many of our states, particularly Florida, Illinois, Indiana, Louisiana, Mississippi, Ohio and Texas. During the year ended December 31, 2015, we received Medicaid premium rate adjustments which yielded a net 1% composite change across all of our markets.

Operating Expenses

Medical Costs

The consolidated HBR for the year ended December 31, 2015 of 88.9% was a decrease of 40 basis points over the comparable period in 2014. The decrease compared to the previous year is primarily attributable to improvement in medical expense in the high acuity populations (LTC/MMP) and membership growth in Medicaid expansion programs and Health Insurance Marketplace, which operate at a lower HBR than traditional Medicaid businesses.

Cost of Services

Cost of services increased by $341 million in the year ended December 31, 2015, compared to the corresponding period in 2014. This was primarily due to growth in the AcariaHealth business. The cost of service ratio for the year ended December 31, 2015, was 86.4% compared to 87.1% in 2014.

Selling, General and Administrative Expenses

SG&A increased by $504 million in the year ended December 31, 2015, compared to the corresponding period in 2014. This was primarily due to expenses for additional staff and facilities to support our membership growth. During the year ended December 31, 2015, we recorded approximately $27 million of Health Net acquisition related expenses, which reduced our diluted earnings per share by $0.14.

During the first quarter of 2015, we recorded a gain of $10 million on the settlement of contingent consideration related to the Community Health Solutions (CHS) transaction. We also recorded expense of $10 million for a contribution to our charitable foundation during the first quarter of 2015.

Also during 2015, we experienced higher than anticipated opt-out rates and member attrition in the new Michigan dual demonstration program, resulting in lower than expected membership and lower blended premium rates. As a result, the fair value of estimated contingent consideration was reduced from $50 million to $16 million, and we recorded a gain of $34 million in SG&A. In connection with the lower membership and revenue outlook, we conducted an impairment analysis of the identifiable intangible assets and goodwill, resulting in a reduction of goodwill and intangible assets of $38 million which was recorded in SG&A. The Company's initial allocation of fair value resulted in goodwill and intangible assets of $52 million. At December 31, 2015, the Company had goodwill of $11 million and other identifiable intangible assets of $1 million, net of $2 million of amortization, remaining on the balance sheet.

The consolidated SG&A expense ratio for the years ended December 31, 2015 and 2014 was 8.5% and 8.3%, respectively. The SG&A ratio for the year ended December 31, 2015 was 8.3% excluding the impact of the Health Net acquisition related expenses. The increase over the prior year is primarily related to the expansion of our Health Insurance Marketplace business which operates at a higher SG&A ratio and incurred higher open enrollment costs in the fourth quarter of 2015.

Other Income (Expense)

The following table summarizes the components of other income (expense) for the year ended December 31, ($ in millions): 

	2015			2014
Investment income	$	27		$	22
Earnings from equity method investments	8			6
Interest expense	(43		)	(35		)
Other income (expense), net	$	(8	)	$	(7	)

The increase in investment income in 2015 reflects an increase in investment balances over 2014 and improved performance of certain equity investments. Interest expense increased during the year ended December 31, 2015 by $8 million primarily reflecting the issuance of $300 million of Senior Notes in April 2014 and the issuance of an additional $200 million in Senior Notes in January 2015.

Income Tax Expense

Our effective tax rate for the year ended December 31, 2015 was 48.6%, compared to 42.9% in 2014. The effective tax rate is higher than the applicable statutory rate primarily as a result of the non-deductibility of the health insurer fee expense.

Segment Results

The following table summarizes our consolidated operating results by segment for the year ended December 31, ($ in millions):

	2015			2014			% Change 2014-2015

Consolidated Total	$	705		$	464		52	%

Managed Care

Total revenues increased 39% in the year ended December 31, 2015, primarily as a result of expansions or new programs in many of our states, particularly Florida, Illinois, Indiana, Louisiana, Mississippi, Ohio and Texas. Earnings from operations increased $160 million between years primarily reflecting growth in the business.

Specialty Services

Total revenues increased 47% in the year ended December 31, 2015, resulting primarily from increased services associated with membership growth in the Managed Care segment and growth in our pharmacy businesses. Earnings from operations increased $81 million in the year ended December 31, 2015, primarily reflecting growth in the specialty services provided to our increased Managed Care membership.

Net increase in cash and cash equivalents	$	2,170		$	150		$	572

Cash Flows Provided by Operating Activities

Normal operations are funded primarily through operating cash flows and borrowings under our revolving credit facility.  Cash flows from operating activities for 2016 were $1,851 million, or 3.3 times net earnings, compared to $658 million in 2015. The cash provided by operations in 2016 was primarily due to net earnings, an increase in accounts payable and accrued expenses and medical claims liabilities, and a decrease in other assets and premium and related receivables. Additionally, cash provided by operations was increased by approximately $445 million in the fourth quarter due to the finalization of the opening balance sheet and respective cash flows for the eight day period from the March 24, 2016 acquisition date to March 31, 2016. 

  Cash flows from operating activities for 2015 decreased to $658 million, compared to $1,223 million in 2014. The cash provided by operations in 2015 and 2014 was primarily related to net earnings and an increase in medical claims liabilities resulting from growth in the business, partially offset by increases in premium and related receivables.

Cash flows from operations in each year were impacted by the timing of payments we received from our states. States may prepay the following month premium payment, which we record as unearned revenue, or they may delay our premium payment, which we record as a receivable. We typically receive capitation payments monthly; however, the states in which we operate may decide to adjust their payment schedules which could positively or negatively impact our reported cash flows from operating activities in any given period. Specifically, at December 31, 2016, the State of Illinois was behind in processing capitation for several months. We continue to monitor the receivable balance and work with the state on the timing of payments.

The reimbursement of the HIF from our state customers may be settled as a separate payment or monthly in combination with our other premium payments. The vast majority of our state customers are settling the reimbursement through a separate payment after verification of each state's portion of our HIF, resulting in an increase in Premium and Related Receivables at December 31, 2016. During 2016, we paid the 2016 annual HIF totaling $513 million. This negatively impacted our cash flows as we have not been reimbursed from many of our state customers. Similarly, during 2015, we paid the 2015 annual HIF invoice totaling $220 million. The table below details the impact to cash flows from operations from the timing of payments from our states ($ in millions).

	Year Ended December 31,
	2016		2015			2014
(Increase) decrease in premium and related receivables	$	74	$	(360	)	$	(463	)
Increase (decrease) in unearned revenue	43		(27		)	129
Net increase (decrease) in operating cash flow	$	117	$	(387	)	$	(334	)

Cash Flows Used in Investing Activities

Investing activities used cash of $2,397 million for the year ended December 31, 2016, and $813 million in the comparable period in 2015. Cash flows used in investing activities in 2016 primarily consisted of our acquisition of Health Net, net additions to the investment portfolio of our regulated subsidiaries, including transfers from cash and cash equivalents to long term investments and capital expenditures.  

In March 2016, we acquired Health Net for approximately $5,990 million, including the assumption of $703 million of debt. The total consideration for the acquisition was $5,287 million, consisting of Centene common shares valued at $3,038 million, $2,247 million in cash, and $2 million related to the fair value adjustment to stock based compensation associated with pre-combination service.

We spent $306 million and $150 million in the year ended December 31, 2016 and 2015, respectively, on capital expenditures for system enhancements and market expansions.

As of December 31, 2016, our investment portfolio consisted primarily of fixed-income securities with a weighted average duration of 3.2 years. We had unregulated cash and investments of $264 million at December 31, 2016, compared to $78 million at December 31, 2015. Unregulated cash and investments include cost and equity method investments and company owned life insurance contracts.

Cash flows used in investing activities in 2015 primarily consisted of additions to the investment portfolio of our regulated subsidiaries, including transfers from cash and cash equivalents to long term investments and capital expenditures.

Cash flows used in investing activities in 2014 primarily consisted of additions to the investment portfolio of our regulated subsidiaries, including transfers from cash and cash equivalents to long term investments, the acquisition of U.S. Medical Management and CHS, an equity investment in Ribera Salud and capital expenditures. We completed the acquisition of U.S. Medical Management for $213 million in total consideration. The transaction was financed through a combination of Centene common stock as well as $80 million of cash. We also completed a transaction with CHS for initial cash consideration of $56 million as well as common stock. Additionally, we purchased a noncontrolling interest in Ribera Salud, S.A. (Ribera Salud), a Spanish health management group for $17 million.

Cash Flows Provided by Financing Activities

Our financing activities provided cash of $2,717 million, $305 million and $198 million in 2016, 2015 and 2014, respectively. Financing activities in 2016, 2015 and 2014 are discussed below.

2016

During 2016, our financing activities primarily related to the proceeds from the issuance of Senior Notes in February 2016 associated with the Health Net acquisition, the issuance of additional Senior Notes in June 2016 and November 2016, partially offset by the redemption of our 5.75% Senior Notes due 2017, the redemption of our 6.375% Senior Notes due 2017, and the repayment of amounts outstanding under our Revolving Credit Facility.

In February 2016, our wholly owned unrestricted subsidiary (Escrow Issuer) issued $1,400 million of 5.625% Senior Notes ($1,400 Million Notes) at par due 2021 and $1,000 million of 6.125% Senior Notes ($1,000 Million Notes) at par due 2024. We used the net proceeds of the offering, together with borrowings under the our new $1,000 million revolving credit facility and cash on hand, to fund the cash consideration for the Health Net acquisition and to pay acquisition and offering related fees and expenses. In connection with the February 2016 issuance, we entered into interest rate swap agreements for notional amounts of $600 million and $1,000 million, at floating rates of interest based on the three month LIBOR plus 4.22% and the three month LIBOR plus 4.44%, respectively. Gains and losses due to changes in the fair value of the interest rate swaps completely offset changes in the fair value of the hedged portion of the underlying debt and are recorded as an adjustment to the $1,400 Million Notes and $1,000 Million Notes.

In connection with the closing of the Health Net acquisition on March 24, 2016, our then-existing unsecured $500 million revolving credit facility was terminated and simultaneously replaced with a new $1,000 million unsecured revolving credit facility (Revolving Credit Facility). Borrowings under the agreement bear interest based upon LIBOR rates, the Federal Funds Rate or the Prime Rate. The agreement has a maturity date of March 24, 2021.

54

In June 2016, we issued an additional $500 million of 4.75% Senior Notes due 2022 at a premium to yield 4.41% ($500 Million Add-on Notes). The $500 Million Add-on Notes were offered as additional debt securities under the indenture governing the $500 million of 4.75% Senior Notes issued April 2014. We used the net proceeds of the offering to repay amounts outstanding under our Revolving Credit Facility and to pay offering related fees and expenses.

In November 2016, we issued an additional $1,200 million of 4.75% Senior Notes due 2025. We used the net proceeds to redeem our $425 million of 5.75% Senior Notes due 2017 and Health Net's $400 million of 6.375% Senior Notes due 2017, to repay amounts outstanding under our Revolving Credit Facility, to pay related fees and expenses and for general purposes.

2015

During 2015, our financing activities primarily related to the proceeds from the issuance of Senior Debt and an additional $150 million of borrowings on our revolving credit facility. In January 2015, we issued an additional $200 million of 4.75% Senior Notes due May 15, 2022 at par (Add on Notes). In connection with the January 2015 issuance, we entered into interest rate swap agreements for a notional amount of $200 million (2015 Swap Agreements) that are scheduled to expire on May 15, 2022. Under the 2015 Swap Agreements, we receive a fixed rate of 4.75% and pay a variable rate of LIBOR plus a spread adjusted quarterly, which allows us to adjust the $200 million Notes to a floating rate. We do not hold or issue any derivative instrument for trading or speculative purposes.

2014

In April 2014, pursuant to a shelf registration statement, we issued $300 million 4.75% Senior Notes due May 15, 2022 at par. Interest is paid semi-annually in May and November. In connection with the issuance, we entered into $300 million notional amount of interest rate swap agreements (2014 Swap Agreements) that are scheduled to expire May 15, 2022. Under the 2014 Swap Agreements, we receive a fixed rate of 4.75% and pay a variable rate of LIBOR plus a spread adjusted quarterly, which allows us to adjust the $300 million Notes to a floating rate. We do not hold or issue any derivative instrument for trading or speculative purposes.

Liquidity Metrics

The credit agreement underlying our Revolving Credit Facility contains non-financial and financial covenants, including requirements of minimum fixed charge coverage ratios and maximum debt-to-EBITDA ratios. We are required to not exceed a maximum debt-to-EBITDA ratio of 3.5 to 1.0 prior to December 31, 2016, and 3.0 to 1.0 on and subsequent to December 31, 2016. As of December 31, 2016, we had $100 million in borrowings outstanding under our revolving credit facility, and we were in compliance with all covenants. As of December 31, 2016, there were no limitations on the availability under the revolving credit agreement as a result of the debt-to-EBITDA ratio.

We had outstanding letters of credit of $71 million as of December 31, 2016, which were not part of our revolving credit facility. We also had letters of credit for $45 million (valued at the December 31, 2016 conversion rate), or €42 million, representing our proportional share of the letters of credit issued to support Ribera Salud's outstanding debt which are a part of the revolving credit facility. Collectively, the letters of credit bore weighted interest of 1.42% as of December 31, 2016. In addition, we had outstanding surety bonds of $365 million as of December 31, 2016.

The indentures governing our various maturities of senior notes contain non-financial and financial covenants of Centene Corporation, including requirements of a minimum fixed charge coverage ratio. As of December 31, 2016, we were in compliance with all covenants.

At December 31, 2016, we had working capital, defined as current assets less current liabilities, of a negative $258 million, compared to a negative $24 million at December 31, 2015. We manage our short term and long term investments with the goal of ensuring that a sufficient portion is held in investments that are highly liquid and can be sold to fund short term requirements as needed.

At December 31, 2016, our debt to capital ratio, defined as total debt divided by the sum of total debt and total equity, was 44.1%, compared to 36.0% at December 31, 2015. Excluding the $64 million non-recourse mortgage note, our debt to capital ratio was 43.7% as of December 31, 2016, compared to 34.7% at December 31, 2015.  The increase in the ratio over the prior year is due to the financing associated with the Health Net acquisition. We utilize the debt to capital ratio as a measure, among others, of our leverage and financial flexibility.

55

We have a stock repurchase program authorizing us to repurchase up to 8 million shares of common stock from time to time on the open market or through privately negotiated transactions. We have 3 million available shares remaining under the program for repurchases as of December 31, 2016. No duration has been placed on the repurchase program. We reserve the right to discontinue the repurchase program at any time. We did not make any repurchases under this plan during 2016, 2015 or 2014.

During the year ended December 31, 2016, 2015 and 2014, we received dividends of $121 million, $11 million, and $50 million, respectively, from our regulated subsidiaries.

2017 Expectations

During 2017, we expect to make net capital contributions to our insurance subsidiaries of approximately $250 million associated with our growth and spend approximately $520 million in additional capital expenditures primarily associated with system integration and enhancements and market expansions. These amounts are expected to be funded by unregulated cash flow generation in 2017 and borrowings on our Revolving Credit Facility. However, from time to time we may elect to raise additional funds for these and other purposes, either through issuance of debt or equity, the sale of investment securities or otherwise, as appropriate. In addition, we may strategically pursue refinancing opportunities to extend maturities and/or improve terms of our indebtedness if we believe such opportunities are favorable to us.

Based on our operating plan, we expect that our available cash, cash equivalents and investments, cash from our operations and cash available under our credit facility will be sufficient to finance our general operations and capital expenditures for at least 12 months from the date of this filing.

CONTRACTUAL OBLIGATIONS

The following table summarizes future contractual obligations. These obligations contain estimates and are subject to revision under a number of circumstances. Our debt consists of borrowings from our senior notes, Revolving Credit Facility, mortgages and capital leases. The purchase obligations consist primarily of software purchases and maintenance contracts. The contractual obligations and estimated period of payment over the next five years and beyond are as follows ($ in millions):

	Payments Due by Period
	Total		Less Than 1 Year		1-3 Years		3-5 Years		More Than 5 Years
Medical claims liability	$	3,929	$	3,929	$	—	$	—	$	—
Debt and interest	6,458		276		564		1,883		3,735
Operating lease obligations	631		133		221		165		112
Purchase obligations	827		446		289		92		—
Other long term liabilities (1)	—		—		—		—		—
Total	$	11,845	$	4,784	$	1,074	$	2,140	$	3,847

(1) Our Consolidated Balance Sheet as of December 31, 2016, includes $869 million of other long term liabilities. This consists primarily of long term deferred income taxes, liabilities under our deferred compensation plan, reserves for uncertain tax positions and retirement benefit obligations. These liabilities have been excluded from the table above as the timing and/or amount of any cash payment is uncertain.

Commitments

In addition, in connection with obtaining regulatory approval of the Health Net acquisition from the California Department of Insurance and the California Department of Managed Health Care, we committed to certain undertakings (the Undertakings). The Undertakings included, among other items, operational commitments around premiums, dividend restrictions, minimum Risk Based Capital (RBC) levels, local offices, growth, accreditation, HEDIS scores and other quality measures, network adequacy, certifications, investments and capital expenditures. Specifically, we agreed to, among other things:

• invest an additional $30 million through the California Organized Investment Network over the five years following completion of the acquisition;

• build a service center in an economically distressed community in California, investing $200 million over 10 years and employing at least 300 people;

56

• contribute $65 million to improve enrollee health outcomes ($10 million over 10 years), support locally-based consumer assistance programs ($5 million over five years) and strengthen the health care delivery system ($50 million over five years), (of which, the present value of $61 million was expensed in the year ended December 31, 2016 and classified as SG&A expenses in the Consolidated Statements of Operations); and

• invest $75 million of its investment portfolio in vehicles supporting California’s health care infrastructure.

The undertakings require significant investments by us, may restrict or impose additional material costs on our future obligations and strategic initiatives in certain geographies, and subject us to various enforcement mechanisms.

REGULATORY CAPITAL AND DIVIDEND RESTRICTIONS

Our operations are conducted through our subsidiaries. As managed care organizations, most of our subsidiaries are subject to state regulations and other requirements that, among other things, require the maintenance of minimum levels of statutory capital, as defined by each state, and restrict the timing, payment and amount of dividends and other distributions that may be paid to us. Generally, the amount of dividend distributions that may be paid by a regulated subsidiary without prior approval by state regulatory authorities is limited based on the entity’s level of statutory net income and statutory capital and surplus.

Our regulated subsidiaries are required to maintain minimum capital requirements prescribed by various regulatory authorities in each of the states in which we operate. As of December 31, 2016, our subsidiaries had aggregate statutory capital and surplus of $4,529 million, compared with the required minimum aggregate statutory capital and surplus requirements of $2,259 million. During the year ended December 31, 2016, we contributed $467 million of net statutory capital to our subsidiaries. For our subsidiaries that file with the National Association of Insurance Commissioners (NAIC), we estimate our RBC percentage (including Kentucky Spirit) to be in excess of 350% of the Authorized Control Level (excluding the interim impact of the health insurance fee).

Under the California Knox-Keene Health Care Service Plan Act of 1975, as amended (“Knox-Keene”), certain of our California subsidiaries must comply with tangible net equity (TNE) requirements. Under these Knox-Keene TNE requirements, actual net worth less unsecured receivables and intangible assets must be more than the greater of (i) a fixed minimum amount, (ii) a minimum amount based on premiums or (iii) a minimum amount based on health care expenditures, excluding capitated amounts. In addition, certain of our California subsidiaries have made certain undertakings to the DMHC to restrict dividends and loans to affiliates, to the extent that the payment of such would reduce such entities' TNE below the required amount as specified in the undertaking.

The NAIC has adopted rules which set minimum risk-based capital requirements for insurance companies, managed care organizations and other entities bearing risk for healthcare coverage. As of December 31, 2016, each of our health plans was in compliance with the risk-based capital requirements enacted in those states.

As a result of the above requirements and other regulatory requirements, certain of our subsidiaries are subject to restrictions on their ability to make dividend payments, loans or other transfers of cash to their parent companies. Such restrictions, unless amended or waived or unless regulatory approval is granted, limit the use of any cash generated by these subsidiaries to pay our obligations. The maximum amount of dividends that can be paid by our insurance company subsidiaries without prior approval of the applicable state insurance departments is subject to restrictions relating to statutory surplus, statutory income and unassigned surplus. As of December 31, 2016, the amount of capital and surplus or net worth that was unavailable for the payment of dividends or return of capital to us was $2,259 million in the aggregate. 

RECENT ACCOUNTING PRONOUNCEMENTS

For this information, refer to Note 2, Summary of Significant Accounting Policies, in the Notes to the Consolidated Financial Statements, included herein.

57

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

Our discussion and analysis of our results of operations and liquidity and capital resources are based on our consolidated financial statements which have been prepared in accordance with GAAP. Our significant accounting policies are more fully described in Note 2, Summary of Significant Accounting Policies, to our consolidated financial statements included elsewhere herein. Our accounting policies regarding medical claims liability and intangible assets are particularly important to the portrayal of our financial position and results of operations and require the application of significant judgment by our management. As a result, they are subject to an inherent degree of uncertainty. We have reviewed these critical accounting policies and related disclosures with the Audit Committee of our Board of Directors.

Goodwill and Intangible Assets

We have made several acquisitions that have resulted in our recording of intangible assets. These intangible assets primarily consist of customer relationships, purchased contract rights, provider contracts, trade names and goodwill. We allocate the fair value of purchase consideration to the assets acquired and liabilities assumed based on their fair values at the acquisition date. The excess of the fair value of consideration transferred over the fair value of the net assets acquired is recorded as goodwill. Goodwill is generally attributable to the value of the synergies between the combined companies and the value of the acquired assembled workforce, neither of which qualifies for recognition as an intangible asset. At December 31, 2016, we had $4,712 million of goodwill and $1,545 million of other intangible assets.

Intangible assets are amortized using the straight-line method over the following periods:

Intangible Asset	Amortization Period
Purchased contract rights	5 - 15 years
Provider contracts	4 - 15 years
Customer relationships	3 - 15 years
Trade names	1 - 20 years
Developed technology	5 years

Our management evaluates whether events or circumstances have occurred that may affect the estimated useful life or the recoverability of the remaining balance of goodwill and other identifiable intangible assets. If the events or circumstances indicate that the remaining balance of the intangible asset or goodwill may be impaired, the potential impairment will be measured based upon the difference between the carrying amount of the intangible asset or goodwill and the fair value of such asset. Our management must make assumptions and estimates, such as the discount factor, future utility and other internal and external factors, in determining the estimated fair values. While we believe these assumptions and estimates are appropriate, other assumptions and estimates could be applied and might produce significantly different results.

Goodwill is reviewed annually during the fourth quarter for impairment. In addition, an impairment analysis of intangible assets would be performed based on other factors. These factors include significant changes in membership, state funding, medical contracts and provider networks and contracts.

We first assess qualitative factors to determine whether it is necessary to perform the two-step quantitative goodwill impairment test. We generally do not calculate the fair value of a reporting unit unless we determine, based on a qualitative assessment, that it is more likely than not that its fair value is less than its carrying amount. However, in certain circumstances, such as recent acquisitions, we may elect to perform a quantitative assessment without first assessing qualitative factors. The fair value of all reporting units with material amounts of goodwill was substantially in excess of the carrying value as of our annual impairment testing date, with the exception of reporting units that were recently acquired without excess fair value on the acquisition date and our home health business, which maintains $267 million of goodwill. During 2016, events and circumstances led to unfavorable results in the home health business, which indicated that the goodwill might be impaired. We completed a quantitative analysis, and the estimate of future undiscounted cash flows indicated that such carrying amounts were expected to be recovered. To the extent the undiscounted cash flows are not sufficient in future periods, the reporting unit could be at risk for impairment.

58

Medical Claims Liability

Our medical claims liability includes claims reported but not yet paid, or inventory, estimates for claims incurred but not reported, or IBNR, and estimates for the costs necessary to process unpaid claims at the end of each period. We estimate our medical claims liability using actuarial methods that are commonly used by health insurance actuaries and meet Actuarial Standards of Practice. These actuarial methods consider factors such as historical data for payment patterns, cost trends, product mix, seasonality, utilization of healthcare services and other relevant factors.  

Actuarial Standards of Practice generally require that the medical claims liability estimates be adequate to cover obligations under moderately adverse conditions. Moderately adverse conditions are situations in which the actual claims are expected to be higher than the otherwise estimated value of such claims at the time of estimate. In many situations, the claims amounts ultimately settled will be different than the estimate that satisfies the Actuarial Standards of Practice. We include in our IBNR an estimate for medical claims liability under moderately adverse conditions which represents the risk of adverse deviation of the estimates in our actuarial method of reserving.

We use our judgment to determine the assumptions to be used in the calculation of the required estimates. The assumptions we consider when estimating IBNR include, without limitation, claims receipt and payment experience (and variations in that experience), changes in membership, provider billing practices, healthcare service utilization trends, cost trends, product mix, seasonality, prior authorization of medical services, benefit changes, known outbreaks of disease or increased incidence of illness such as influenza, provider contract changes, changes to fee schedules, and the incidence of high dollar or catastrophic claims.

 We apply various estimation methods depending on the claim type and the period for which claims are being estimated. For more recent periods, incurred non-inpatient claims are estimated based on historical per member per month claims experience adjusted for known factors. Incurred hospital inpatient claims are estimated based on known inpatient utilization data and prior claims experience adjusted for known factors. For older periods, we utilize an estimated completion factor based on our historical experience to develop IBNR estimates. The completion factor is an actuarial estimate of the percentage of claims incurred during a given period that have been received or adjudicated as of the reporting period to the estimate of the total ultimate incurred costs. When we commence operations in a new state or region, we have limited information with which to estimate our medical claims liability. See “Risk Factors - Failure to accurately estimate and price our medical expenses or effectively manage our medical costs or related administrative costs could negatively affect our financial position, results of operations or cash flows.” These approaches are consistently applied to each period presented.

Additionally, we contract with independent actuaries to review our estimates on a quarterly basis. The independent actuaries provide us with a review letter that includes the results of their analysis of our medical claims liability. We do not solely rely on their report to adjust our claims liability. We utilize their calculation of our claims liability only as additional information, together with management's judgment, to determine the assumptions to be used in the calculation of our liability for claims.

Our development of the medical claims liability estimate is a continuous process which we monitor and refine on a monthly basis as additional claims receipts and payment information becomes available. As more complete claims information becomes available, we adjust the amount of the estimates, and include the changes in estimates in medical costs in the period in which the changes are identified. In every reporting period, our operating results include the effects of more completely developed medical claims liability estimates associated with previously reported periods. We consistently apply our reserving methodology from period to period. As additional information becomes known to us, we adjust our actuarial models accordingly to establish medical claims liability estimates.

59

The paid and received completion factors, claims per member per month and per diem cost trend factors are the most significant factors affecting the IBNR estimate. The following table illustrates the sensitivity of these factors and the estimated potential impact on our operating results caused by changes in these factors based on December 31, 2016 data:

Completion Factors: (1)					Cost Trend Factors: (2)
(Decrease) Increase in Factors		Increase (Decrease) in Medical Claims Liabilities			(Decrease) Increase in Factors		Increase (Decrease) in Medical Claims Liabilities

(2) Reflects estimated potential changes in medical claims liability caused by changes in cost trend factors for the most recent periods.

While we believe our estimates are appropriate, it is possible future events could require us to make significant adjustments for revisions to these estimates. For example, a 1% increase or decrease in our estimated medical claims liability would have affected net earnings by $25 million for the year ended December 31, 2016, excluding the effect of any return of premium, risk corridor, or minimum MLR programs. The estimates are based on our historical experience, terms of existing contracts, our observance of trends in the industry, information provided by our providers and information available from other outside sources.

The change in medical claims liability is summarized as follows (in millions):

(1) Days in claims payable is a calculation of medical claims liability at the end of the period divided by average expense per calendar day for the fourth quarter of each year.

Medical claims are usually paid within a few months of the member receiving service from the physician or other healthcare provider. As a result, the liability generally is described as having a “short-tail,” which causes less than 5% of our medical claims liability as of the end of any given year to be outstanding the following year. We believe that substantially all the development of the estimate of medical claims liability as of December 31, 2016 will be known by the end of 2017.

Changes in estimates of incurred claims for prior years are primarily attributable to reserving under moderately adverse conditions. Additionally, as a result of minimum HBR and other return of premium programs, approximately $39 million, $47 million and $26 million of the “Incurred related to: Prior years” was recorded as a reduction to premium revenues in 2016, 2015 and 2014, respectively. Further, claims processing initiatives yielded increased claim payment recoveries and coordination of benefits related to prior year dates of service. Changes in medical utilization and cost trends and the effect of medical management initiatives may also contribute to changes in medical claim liability estimates. While we have evidence that medical management initiatives are effective on a case by case basis, medical management initiatives primarily focus on events and behaviors prior to the incurrence of the medical event and generation of a claim. Accordingly, any change in behavior, leveling of care, or coordination of treatment occurs prior to claim generation and as a result, the costs prior to the medical management initiative are not known by us. Additionally, certain medical management initiatives are focused on member and provider education with the intent of influencing behavior to appropriately align the medical services provided with the member's acuity. In these cases, determining whether the medical management initiative changed the behavior cannot be determined. Because of the complexity of our business, the number of states in which we operate, and the volume of claims that we process, we are unable to practically quantify the impact of these initiatives on our changes in estimates of IBNR.

The following are examples of medical management initiatives that may have contributed to the favorable development through lower medical utilization and cost trends:

• Appropriate leveling of care for neonatal intensive care unit hospital admissions, other inpatient hospital admissions, and observation admissions, in accordance with Interqual or other criteria.

• Management of our pre-authorization list and more stringent review of durable medical equipment and injectibles.

• Emergency room program designed to collaboratively work with hospitals to steer non-emergency care away from the costly emergency room setting (through patient education, on-site alternative urgent care settings, etc.)

• Increase emphasis on case management and clinical rounding where case managers are nurses or social workers who are employed by the health plan to assist selected patients with the coordination of healthcare services in order to meet a patient's specific healthcare needs.

• Incorporation of disease management which is a comprehensive, multidisciplinary, collaborative approach to chronic illnesses such as asthma.

• Prenatal and infant health programs utilized in our Start Smart For Your Baby outreach service.

Revenue Recognition

Our health plans generate revenues primarily from premiums received from the states in which we operate health plans. We generally receive a fixed premium per member per month pursuant to our state contracts and recognize premium revenues during the period in which we are obligated to provide services to our members at the amount reasonably estimable. In some instances, our base premiums are subject to an adjustment, or risk score, based on the acuity of its membership. Generally, the risk score is determined by the State analyzing submissions of processed claims data to determine the acuity of our membership relative to the entire state's Medicaid membership. We estimate the amount of risk adjustment based upon the processed claims data submitted and expected to be submitted to CMS and record revenues on a risk adjusted basis. Some contracts allow for additional premiums related to certain supplemental services provided such as maternity deliveries.

Our contracts with states may require us to maintain a minimum HBR or may require us to share profits in excess of certain levels. In certain circumstances, our plans may be required to return premium to the state in the event profits exceed established levels. We estimate the effect of these programs and recognize reductions in revenue in the current period. Other states may require us to meet certain performance and quality metrics in order to receive additional or full contractual revenue. For performance-based contracts, we do not recognize revenue subject to refund until data is sufficient to measure performance.

Revenues are recorded based on membership and eligibility data provided by the states, which is adjusted on a monthly basis by the states for retroactive additions or deletions to membership data. These eligibility adjustments are estimated monthly and subsequent adjustments are made in the period known. We continuously review and updates those estimates as new information becomes available. It is possible that new information could require us to make additional adjustments, which could be significant, to these estimates.

61

Our Medicare Advantage contracts are with CMS. CMS deploys a risk adjustment model which apportions premiums paid to all health plans according to health severity and certain demographic factors. The CMS risk adjustment model pays more for members whose medical history would indicate that they are expected to have higher medical costs. Under this risk adjustment methodology, CMS calculates the risk adjusted premium payment using diagnosis data from hospital inpatient, hospital outpatient, physician treatment settings as well as prescription drug events. We and the health care providers collect, compile and submit the necessary and available diagnosis data to CMS within prescribed deadlines. We estimate risk adjustment revenues based upon the diagnosis data submitted and expected to be submitted to CMS and record revenues on a risk adjusted basis.

Our specialty services generate revenues under contracts with state and federal programs, healthcare organizations and other commercial organizations, as well as from our own subsidiaries. Revenues are recognized when the related services are provided or as ratably earned over the covered period of services. We recognize revenue related to administrative services under the T-3 TRICARE government-sponsored managed care support contract in the North Region for the DoD's TRICARE program (T-3 contract) on a straight-line basis over the option period, when the fees become fixed and determinable. The T-3 contract includes various performance-based incentives and penalties. For each of the incentives or penalties, we adjust revenue accordingly based on the amount that it has earned or incurred at each interim date and are legally entitled to in the event of a contract termination.

Some states enact premium taxes, similar assessments and provider pass-through payments, collectively premium taxes, and these taxes are recorded as a separate component of both revenues and operating expenses. Additionally, our insurance subsidiaries are subject to the Affordable Care Act annual HIF. If we are able to negotiate reimbursement of portions of these premium taxes or the HIF, we recognize revenue associated with the HIF on a straight-line basis when we have binding agreements for such reimbursements, including the “gross-up” to reflect the HIFs non-tax deductible nature. Collectively, this revenue is recorded as premium tax and health insurer fee revenue in the Consolidated Statements of Operations.

ITEM 7A. Quantitative and Qualitative Disclosures About Market Risk

INVESTMENTS AND DEBT

As of December 31, 2016, we had short term investments of $505 million and long term investments of $4,683 million, including restricted deposits of $138 million. The short term investments generally consist of highly liquid securities with maturities between three and 12 months. The long term investments consist of municipal, corporate and U.S. Treasury securities, government sponsored obligations, life insurance contracts, asset backed securities and equity securities and have maturities greater than one year. Restricted deposits consist of investments required by various state statutes to be deposited or pledged to state agencies. Due to the nature of the states’ requirements, these investments are classified as long term regardless of the contractual maturity date. Substantially all of our investments are subject to interest rate risk and will decrease in value if market rates increase. Assuming a hypothetical and immediate 1% increase in market interest rates at December 31, 2016, the fair value of our fixed income investments would decrease by approximately $155 million.  Declines in interest rates over time will reduce our investment income.

We have interest rate swap agreements for a notional amount of $2,100 million with creditworthy financial institutions to manage the impact of market interest rates on interest expense. Our swap agreements convert a portion of our interest expense from fixed to variable rates to better match the impact of changes in market rates on our variable rate cash equivalent investments. As a result, the fair value of $2,100 million of our long term debt varies with market interest rates. Assuming a hypothetical and immediate 1% increase in market interest rates at December 31, 2016, the fair value of our debt would decrease by approximately $107 million. An increase in interest rates decreases the fair value of the debt and conversely, a decrease in interest rates increases the value.

For a discussion of the interest rate risk that our investments are subject to, see "Risk Factors – Our investment portfolio may suffer losses which could materially and adversely affect our results of operations or liquidity.”

62

INFLATION

The inflation rate for medical care costs has been higher than the overall inflation rate for all items. We use various strategies to mitigate the negative effects of healthcare cost inflation.  Specifically, our health plans try to control medical and hospital costs through our state savings initiatives and contracts with independent providers of healthcare services. Through these contracted care providers, our health plans emphasize preventive healthcare and appropriate use of specialty and hospital services. Additionally, our contracts with states require actuarially sound premiums that include healthcare cost trend.

While we currently believe our strategies to mitigate healthcare cost inflation will continue to be successful, competitive pressures, new healthcare and pharmaceutical product introductions, demands from healthcare providers and customers, applicable regulations, an increase in the expected rate of inflation for healthcare costs or other factors may affect our ability to control the impact of healthcare cost increases.

CENTENE CORPORATION AND SUBSIDIARIES

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

1. Organization and Operations

Centene Corporation, or the Company, is a diversified, multi-national healthcare enterprise operating in two segments: Managed Care and Specialty Services. The Managed Care segment provides Medicaid and Medicaid-related health plan coverage to individuals through the government subsidized programs, including Medicaid, the State Children's Health Insurance Program (CHIP), Long Term Care (LTC), Foster Care, dual-eligible individuals (Duals) in Medicare Special Needs Plans and the Supplemental Security Income Program, also known as the Aged, Blind or Disabled Program (ABD), Medicare, and the Health Insurance Marketplace. The Company also offers a variety of individual, small group, and large group commercial health care products, both to employers and directly to members in the Managed Care segment. The Specialty Services segment consists of our specialty companies offering auxiliary healthcare services and products to state programs, correctional facilities, healthcare organizations, employer groups and other commercial organizations, as well as to our own subsidiaries. The Specialty Service segment also includes the Government Contracts business which includes the Company's government-sponsored managed care support contract with the U.S. Department of Defense (DoD) under the TRICARE program in the North Region, the Military Family and Life Counseling (MFLC) contract with the DoD, and other health care related government contracts, including the Patient Centered Community Care (PC3) contract with the U.S. Department of Veterans Affairs (VA).

On March 24, 2016, the Company acquired all of the issued and outstanding shares of Health Net, Inc. (Health Net) a publicly traded managed care organization that delivers health care services through health plans and government-sponsored managed care plans. The transaction was valued at approximately $5,990 million, including the assumption of $703 million of outstanding debt. The acquisition allows the Company to offer a more comprehensive and scalable portfolio of solutions and provides opportunity for additional growth across the combined company's markets.

On February 2, 2015, the Board of Directors declared a two-for-one split of Centene's common stock in the form of a 100% stock dividend distributed February 19, 2015 to stockholders of record on February 12, 2015. All share and per share information presented in this Form 10-K has been adjusted for the two-for-one stock split.

Basis of Presentation

The accompanying consolidated financial statements include the accounts of Centene Corporation and all majority owned subsidiaries and subsidiaries over which the Company exercises the power and control to direct activities significantly impacting financial performance. All material intercompany balances and transactions have been eliminated. The assets, liabilities and results of operations of Kentucky Spirit Health Plan (Kentucky Spirit) are classified as discontinued operations for all periods presented.

Certain amounts in the consolidated financial statements and notes have been reclassified to conform to the 2016 presentation. These reclassifications have no effect on net earnings or stockholders' equity as previously reported.

Use of Estimates

The preparation of financial statements in conformity with generally accepted accounting principles in the United States, or GAAP, requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Future events and their effects cannot be predicted with certainty; accordingly, the accounting estimates require the exercise of judgment. The accounting estimates used in the preparation of the consolidated financial statements will change as new events occur, as more experience is acquired, as additional information is obtained and as the operating environment changes. The Company evaluates and updates its assumptions and estimates on an ongoing basis and may employ outside experts to assist in our evaluation, as considered necessary. Actual results could differ from those estimates.

70

Business Combinations

Business combinations are accounted for using the acquisition method of accounting. The Company allocates the fair value of purchase consideration to the assets acquired and liabilities assumed based on their fair values at the acquisition date. The excess of the fair value of consideration transferred over the fair value of the net assets acquired is recorded as goodwill. Goodwill is generally attributable to the value of the synergies between the combined companies and the value of the acquired assembled workforce, neither of which qualifies for recognition as an intangible asset.

The Company uses its best estimates and assumptions to value assets acquired and liabilities assumed at the acquisition date; however, these estimates are sometimes preliminary and in some instances, all information required to value the assets acquired and liabilities assumed may not be available or final as of the end of a reporting period subsequent to the business combination. If the accounting for the business combination is incomplete, provisional amounts are recorded. The provisional amounts are updated during the period determined, up to one year from the acquisition date. The Company includes the results of operations of acquired businesses in the Company's consolidated results prospectively from the date of acquisition.

Acquisition related expenses and post-acquisition restructuring costs are recognized separately from the business combination and are expensed as incurred.

Cash and Cash Equivalents

Investments with original maturities of three months or less are considered to be cash equivalents. Cash equivalents consist of money market funds and bank certificates of deposit and savings accounts.

The Company maintains amounts on deposit with various financial institutions, which may exceed federally insured limits. However, management periodically evaluates the credit-worthiness of those institutions, and the Company has not experienced any losses on such deposits.

Investments

Short term investments include securities with maturities greater than three months to one year. Long term investments include securities with maturities greater than one year.

Short term and long term investments are generally classified as available for sale and are carried at fair value. Certain equity investments are recorded using the cost or equity method. Unrealized gains and losses on investments available for sale are excluded from earnings and reported in accumulated other comprehensive income, a separate component of stockholders' equity, net of income tax effects. Premiums and discounts are amortized or accreted over the life of the related security using the effective interest method. The Company monitors the difference between the cost and fair value of investments. Investments that experience a decline in value that is judged to be other than temporary are written down to fair value and a realized loss is recorded in investment and other income. To calculate realized gains and losses on the sale of investments, the Company uses the specific amortized cost of each investment sold. Realized gains and losses are recorded in investment and other income.

The Company uses the equity method to account for its investments in entities that it does not control but has the ability to exercise significant influence over operating and financial policies. These investments are recorded at the lower of their cost or fair value adjusted for the Company's proportionate share of earnings or losses.

Restricted Deposits

Restricted deposits consist of investments required by various state statutes to be deposited or pledged to state agencies. These investments are classified as long term, regardless of the contractual maturity date, due to the nature of the states' requirements. The Company is required to annually adjust the amount of the deposit pledged to certain states.

71

Fair Value Measurements

In the normal course of business, the Company invests in various financial assets and incurs various financial liabilities. Fair values are disclosed for all financial instruments, whether or not such values are recognized in the Consolidated Balance Sheets. Management obtains quoted market prices and other observable inputs for these disclosures. The carrying amounts reported in the Consolidated Balance Sheets for cash and cash equivalents, premium and related receivables, medical claims liability, accounts payable and accrued expenses, unearned revenue, and certain other current assets and liabilities are carried at cost, which approximates fair value because of their short term nature.

The following methods and assumptions were used to estimate the fair value of each financial instrument:

• Available for sale investments and restricted deposits: The carrying amount is stated at fair value, based on quoted market prices, where available. For securities not actively traded, fair values were estimated using values obtained from independent pricing services or quoted market prices of comparable instruments.

• Senior unsecured notes: Estimated based on third-party quoted market prices for the same or similar issues.

• Variable rate debt: The carrying amount of our floating rate debt approximates fair value since the interest rates adjust based on market rate adjustments.

• Interest rate swap: Estimated based on third-party market prices based on the forward 3-month LIBOR curve.

• Contingent consideration: Estimated based on expected achievement of metrics included in the acquisition agreement considering circumstances that exist as of the acquisition date.

Property, Software and Equipment

Property, software and equipment are stated at cost less accumulated depreciation. Capitalized software includes certain costs incurred in the development of internal-use software, including external direct costs of materials and services and payroll costs of employees devoted to specific software development. Depreciation is calculated principally by the straight-line method over estimated useful lives. Leasehold improvements are depreciated using the straight-line method over the shorter of the expected useful life or the remaining term of the lease. Property, software and equipment are depreciated over the following periods:

Fixed Asset	Depreciation Period
Buildings and land improvements	5 - 40 years
Computer hardware and software	2 - 7 years
Furniture and equipment	3 - 10 years
Land improvements	3 - 20 years
Leasehold improvements	1 - 20 years

The carrying amounts of all long-lived assets are evaluated to determine if adjustment to the depreciation and amortization period or to the unamortized balance is warranted. Such evaluation is based principally on the expected utilization of the long-lived assets.

The Company retains fully depreciated assets in property and accumulated depreciation accounts until it removes them from service. In the case of sale, retirement, or disposal, the asset cost and related accumulated depreciation balance is removed from the respective account, and the resulting net amount, less any proceeds, is included as a component of earnings from operations in the Consolidated Statements of Operations.

72

Goodwill andIntangible Assets

Intangible assets represent assets acquired in purchase transactions and consist primarily of purchased contract rights, provider contracts, customer relationships, trade names, developed technologies and goodwill. Intangible assets are amortized using the straight-line method over the following periods:

Intangible Asset	Amortization Period
Purchased contract rights	5 - 15 years
Provider contracts	4 - 15 years
Customer relationships	3 - 15 years
Trade names	1 - 20 years
Developed technology	5 years

The Company tests for impairment of intangible assets as well as long-lived assets whenever events or changes in circumstances indicate that the carrying value of an asset or asset group (hereinafter referred to as “asset group”) may not be recoverable by comparing the sum of the estimated undiscounted future cash flows expected to result from use of the asset group and its eventual disposition to the carrying value. Such factors include, but are not limited to, significant changes in membership, state funding, state contracts and provider networks and contracts. If the sum of the estimated undiscounted future cash flows is less than the carrying value, an impairment determination is required. The amount of impairment is calculated by subtracting the fair value of the asset group from the carrying value of the asset group. An impairment charge, if any, is recognized within earnings from operations.

The Company tests goodwill for impairment using a fair value approach. The Company is required to test for impairment at least annually, absent a triggering event, which could include a significant decline in operating performance that would require an impairment assessment. Absent any impairment indicators, the Company performs its goodwill impairment testing during the fourth quarter of each year. The Company recognizes an impairment charge for any amount by which the carrying amount of goodwill exceeds its implied fair value.

The Company first assesses qualitative factors to determine whether it is necessary to perform the two-step quantitative goodwill impairment test. The Company generally does not calculate the fair value of a reporting unit unless it determines, based on a qualitative assessment, that it is more likely than not that its fair value is less than its carrying amount. However, in certain circumstances, such as recent acquisitions, the Company may elect to perform a quantitative assessment without first assessing qualitative factors.

If the two-step quantitative test is deemed necessary, the Company determines an appropriate valuation technique to estimate a reporting unit's fair value as of the testing date. The Company utilizes either the income approach or the market approach, whichever is most appropriate for the respective reporting unit. The income approach is based on an internally developed discounted cash flow model that includes many assumptions related to future growth rates, discount factors, future tax rates, etc. The market approach is based on financial multiples of comparable companies derived from current market data. Changes in economic and operating conditions impacting assumptions used in our analyses could result in goodwill impairment in future periods.

Medical Claims Liability

Medical claims liability includes claims reported but not yet paid, or inventory, estimates for claims incurred but not reported, or IBNR, and estimates for the costs necessary to process unpaid claims at the end of each period. The Company estimates its medical claims liability using actuarial methods that are commonly used by health insurance actuaries and meet Actuarial Standards of Practice. These actuarial methods consider factors such as historical data for payment patterns, cost trends, product mix, seasonality, utilization of healthcare services and other relevant factors.  

Actuarial Standards of Practice generally require that the medical claims liability estimates be adequate to cover obligations under moderately adverse conditions. Moderately adverse conditions are situations in which the actual claims are expected to be higher than the otherwise estimated value of such claims at the time of estimate. In many situations, the claims amounts ultimately settled will be different than the estimate that satisfies the Actuarial Standards of Practice. The Company includes in its IBNR an estimate for medical claims liability under moderately adverse conditions which represents the risk of adverse deviation of the estimates in its actuarial method of reserving.

73

The Company uses its judgment to determine the assumptions to be used in the calculation of the required estimates. The assumptions it considers when estimating IBNR include, without limitation, claims receipt and payment experience (and variations in that experience), changes in membership, provider billing practices, healthcare service utilization trends, cost trends, product mix, seasonality, prior authorization of medical services, benefit changes, known outbreaks of disease or increased incidence of illness such as influenza, provider contract changes, changes to fee schedules, and the incidence of high dollar or catastrophic claims.

The Company's development of the medical claims liability estimate is a continuous process which it monitors and refines on a monthly basis as additional claims receipts and payment information becomes available. As more complete claims information becomes available, the Company adjusts the amount of the estimates, and includes the changes in estimates in medical costs in the period in which the changes are identified. In every reporting period, the operating results include the effects of more completely developed medical claims liability estimates associated with previously reported periods. The Company consistently applies its reserving methodology from period to period. As additional information becomes known, it adjusts the actuarial model accordingly to establish medical claims liability estimates.

 The Company periodically reviews actual and anticipated experience compared to the assumptions used to establish medical costs. The Company establishes premium deficiency reserves if actual and anticipated experience indicates that existing policy liabilities together with the present value of future gross premiums will not be sufficient to cover the present value of future benefits, settlement and maintenance costs.    

Revenue Recognition

The Company's health plans generate revenues primarily from premiums received from the states in which it operates health plans. The Company generally receives a fixed premium per member per month pursuant to its state contracts and recognizes premium revenues during the period in which it is obligated to provide services to its members at the amount reasonably estimable. In some instances, the Company's base premiums are subject to an adjustment, or risk score, based on the acuity of its membership. Generally, the risk score is determined by the State analyzing submissions of processed claims data to determine the acuity of the Company's membership relative to the entire state's Medicaid membership. The Company estimates the amount of risk adjustment based upon the processed claims data submitted and expected to be submitted to Centers for Medicare and Medicaid Services (CMS) and records revenues on a risk adjusted basis. Some contracts allow for additional premiums related to certain supplemental services provided such as maternity deliveries.

The Company's contracts with states may require us to maintain a minimum health benefits ratio (HBR) or may require us to share profits excess of certain levels. In certain circumstances, our plans may be required to return premium to the state in the event profits exceed established levels. We estimate the effect of these programs and recognize reductions in revenue in the current period. Other states may require us to meet certain performance and quality metrics in order to receive additional or full contractual revenue. For performance-based contracts, we do not recognize revenue subject to refund until data is sufficient to measure performance.

Revenues are recorded based on membership and eligibility data provided by the states, which is adjusted on a monthly basis by the states for retroactive additions or deletions to membership data. These eligibility adjustments are estimated monthly and subsequent adjustments are made in the period known. The Company continuously reviews and updates those estimates as new information becomes available. It is possible that new information could require us to make additional adjustments, which could be significant, to these estimates.

The Company's Medicare Advantage contracts are with CMS. CMS deploys a risk adjustment model which apportions premiums paid to all health plans according to health severity and certain demographic factors. The CMS risk adjustment model pays more for members whose medical history would indicate that they are expected to have higher medical costs. Under this risk adjustment methodology, CMS calculates the risk adjusted premium payment using diagnosis data from hospital inpatient, hospital outpatient, physician treatment settings as well as prescription drug events. The Company and the health care providers collect, compile and submit the necessary and available diagnosis data to CMS within prescribed deadlines. The Company estimates risk adjustment revenues based upon the diagnosis data submitted and expected to be submitted to CMS and records revenues on a risk adjusted basis.

74

The Company's specialty services generate revenues under contracts with state and federal programs, healthcare organizations and other commercial organizations, as well as from our own subsidiaries. Revenues are recognized when the related services are provided or as ratably earned over the covered period of services. The Company recognizes revenue related to administrative services under the T-3 TRICARE government-sponsored managed care support contract in the North Region for the DoD's TRICARE program (T-3 contract) on a straight-line basis over the option period, when the fees become fixed and determinable. The T-3 contract includes various performance-based incentives and penalties. For each of the incentives or penalties, the Company adjusts revenue accordingly based on the amount that it has earned or incurred at each interim date and are legally entitled to in the event of a contract termination.

Some states enact premium taxes, similar assessments and provider pass-through payments, collectively premium taxes, and these taxes are recorded as a separate component of both revenues and operating expenses. Additionally, the Company's insurance subsidiaries are subject to the Affordable Care Act annual health insurer fee (HIF). If the Company is able to negotiate reimbursement of portions of these premium taxes or the HIF, it recognizes revenue associated with the HIF on a straight-line basis when we have binding agreements for such reimbursements, including the “gross-up” to reflect the HIFs non-tax deductible nature. Collectively, this revenue is recorded as premium tax and health insurer fee revenue in the Consolidated Statements of Operations.

Affordable Care Act

The Affordable Care Act (ACA) established risk spreading premium stabilization programs effective January 1, 2014. These programs, commonly referred to as the “three Rs”, include a permanent risk adjustment program, a transitional reinsurance program, and a temporary risk corridor program. Additionally, the ACA established a minimum annual medical loss ratio (MLR) and cost-sharing reductions. Each of the three R programs are taken into consideration to determine if the Company's estimated annual medical costs are less than the minimum loss ratio and require an adjustment to premium revenue to meet the minimum MLR.

During the second quarter of 2016, the Company recognized a $70 million net pre-tax benefit related to the reconciliation of 2015 risk adjustment and reinsurance programs. During the third quarter of 2016, the company received information from CMS, indicating that some of the participants in the Arizona risk adjustment program were unable to pay the amounts owed. As a result, the uncollected portion has been allocated pro-rata to other insurers in the market. Accordingly, the Company reduced the pre-tax earnings by $19 million during the third quarter.

The Company’s accounting policies for the programs are as follows:

Risk Adjustment

The permanent risk adjustment program established by the ACA transfers funds from qualified individual and small group insurance plans with below average risk scores to those plans with above average risk scores within each state. The Company estimates the receivable or payable under the risk adjustment program based on its estimated risk score compared to the state average risk score. The Company may record a receivable or payable as an adjustment to Premium revenue to reflect the year to date impact of the risk adjustment based on its best estimate. The Company expects to refine its estimate as new information becomes available. As of December 31, 2016 and 2015, the Company recorded a payable of $425 million and $108 million, respectively, associated with risk adjustment.

Reinsurance

The ACA established a transitional three-year reinsurance program whereby the Company’s claims costs incurred for qualified members will be reimbursed when they exceed a specific threshold. For the 2016 benefit year, qualified member claims that exceeded $90,000 entitled the Company to reimbursement from the programs at 50% coinsurance. The Company accounts for reinsurance recoveries as a reduction of Medical Costs based on each individual case that exceeds the reinsurance threshold established by the program. As of December 31, 2016 and 2015, the Company recorded a receivable of $122 million and $24 million, respectively, associated with reinsurance.

75

Risk Corridor

The temporary, three-year risk corridor program established by the ACA applies to qualified individual and small group health plans operating both inside and outside of the Health Insurance Marketplace. The risk corridor program limits the Company’s gains and losses in the Health Insurance Marketplace by comparing certain medical and administrative costs to a target amount and sharing the risk for allowable costs with the federal government. Allowable medical costs are adjusted for risk adjustment settlements, transitional reinsurance recoveries, and cost sharing reductions received from the federal government. The Company records a risk corridor receivable or payable as an adjustment to premium revenue on a year to date basis based on where its estimated annual costs fall within the risk corridor range. As of December 31, 2016 and 2015, the Company recorded a payable of $3 million and $4 million, respectively, associated with risk corridor.

Minimum Medical Loss Ratio

Additionally, the ACA established a minimum annual MLR for the Health Insurance Marketplace. Each of the three R programs described above are taken into consideration to determine if the Company’s estimated annual medical costs are less than the minimum loss ratio and require an adjustment to premium revenue to meet the minimum MLR. As of December 31, 2016 and 2015, the Company recorded a payable of $18 million and $15 million, respectively, associated with minimum MLR.

Cost-sharing Reductions (CSRs)

The ACA directs issuers to reduce the Company's members' cost sharing for essential health benefits for individuals with Federal Poverty Levels (FPLs) between 100% and 250% who are enrolled in a silver tier product; eliminate cost sharing for Indians/Alaska Natives with an FPL less than 300% and eliminate cost sharing for Indians/Alaska Natives regardless of FPL level when services are provided by an Indian Health Service. In order to compensate issuers for reduced cost sharing provided to enrollees, CMS pays an advance CSR payment to the Company each month based on the Company’s certification data provided at the time of the qualified health plan application. After the close of the benefit year, the Company is required to provide CMS with data on the value of the CSRs provided to enrollees based on either a ‘simplified’ or ‘standard’ approach. A reconciliation will occur in order to calculate the difference between the Company’s CSR advance payments received and the value of CSRs provided to enrollees. This reconciliation will produce either a payable or receivable to/from CMS. The Company has elected the standard methodology approach. As of December 31, 2016 and 2015, the Company recorded a payable of $147 million and $40 million, respectively, associated with CSRs.

Premium and Related Receivables and Unearned Revenue

Premium and service revenues collected in advance are recorded as unearned revenue. For performance-based contracts the Company does not recognize revenue subject to refund until data is sufficient to measure performance. Premiums and service revenues due to the Company are recorded as premium and related receivables and are recorded net of an allowance based on historical trends and management's judgment on the collectibility of these accounts. As the Company generally receives payments during the month in which services are provided, the allowance is typically not significant in comparison to total revenues and does not have a material impact on the presentation of the financial condition or results of operations. Amounts receivable under federal contracts are comprised primarily of contractually defined billings, accrued contract incentives under the terms of the contract and amounts related to change orders for services not originally specified in the contract.

Activity in the allowance for uncollectible accounts for the years ended December 31, is summarized below ($ in millions):

	2016			2015			2014
Allowances, beginning of year	$	10		$	5		$	1
Amounts charged to expense	33			12			8
Write-offs of uncollectible receivables	(14		)	(7		)	(4		)
Allowances, end of year	$	29		$	10		$	5

76

Significant Customers

Centene receives the majority of its revenues under contracts or subcontracts with state Medicaid managed care programs. The current contracts expire on various dates between February 28, 2017 and December 31, 2022. Customers where the aggregate annual contract revenues exceeded 10% of total annual revenues included the state of California, where the percentage of the Company's total revenue was 21%, 3% and 2% for the years ended December 31, 2016, 2015 and 2014, respectively; the state of Florida, where the percentage of the Company's total revenue was 14% for the years ended December 31, 2015 and 2014; and the state of Texas, where the percentage of the Company's total revenue was 13%, 22% and 25% for the years ended December 31, 2016, 2015 and 2014, respectively. The decrease in the revenue percentage for the state of Texas compared to prior periods is attributable to the overall growth in the Company's revenues as a result of the Health Net acquisition.

Other Income (Expense)

Other income (expense) consists principally of investment income, interest expense and equity method earnings from investments. Investment income is derived from the Company's cash, cash equivalents, restricted deposits and investments. Interest expense relates to borrowings under the senior notes, interest rate swap, credit facilities, interest on capital leases and credit facility fees.

Income Taxes

Deferred tax assets and liabilities are recorded for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax law or tax rates is recognized in income in the period that includes the enactment date.

Valuation allowances are provided when it is considered more likely than not that deferred tax assets will not be realized. In determining if a deductible temporary difference or net operating loss can be realized, the Company considers future reversals of existing taxable temporary differences, future taxable income, taxable income in prior carryback periods and tax planning strategies.

Contingencies

The Company accrues for loss contingencies associated with outstanding litigation, claims and assessments for which it has determined it is probable that a loss contingency exists and the amount of loss can be reasonably estimated. The Company expenses professional fees associated with litigation claims and assessments as incurred.

Stock Based Compensation

The fair value of the Company's employee share options and similar instruments are estimated using the Black-Scholes option-pricing model. That cost is recognized over the period during which an employee is required to provide service in exchange for the award. Excess tax benefits related to stock compensation are presented as a cash inflow from financing activities for the years ended December 31, 2015 and 2014 and as a cash inflow from operating activities for the year ended December 31, 2016 due to the prospective adoption of employee share-based payment guidance in 2016. The Company accounts for forfeitures when they occur.

Foreign Currency Translation

The Company is exposed to foreign currency exchange risk through its equity method investment in Ribera Salud S.A. (Ribera Salud), a Spanish health management group whose functional currency is the Euro. The assets and liabilities of the Company's investment are translated into United States dollars at the balance sheet date. The Company translates its proportionate share of earnings using average rates during the year. The resulting foreign currency translation adjustments are recorded as a separate component of accumulated other comprehensive income.

77

Recently Adopted Accounting Pronouncements

In March 2016, the Financial Accounting Standards Board (FASB) issued an Accounting Standards Update (ASU) which simplifies several aspects of the accounting for employee share-based payment transactions, including the accounting for income taxes, forfeitures, and statutory tax withholding requirements, as well as classification in the statement of cash flows. Under the new guidance, an entity recognizes all excess tax benefits and tax deficiencies as income tax expense or benefit in the income statement. The ASU also allows an entity to elect as an accounting policy either to continue to estimate the total number of awards for which the requisite service period will not be rendered, as currently required, or to account for forfeitures when they occur. Finally, the ASU modifies the current exception to liability classification of an award when an employer uses a net-settlement feature to withhold shares to meet the employee's minimum statutory tax withholding requirement. The new standard is effective for annual periods beginning after December 15, 2016, including interim periods within those annual reporting periods. Early adoption is permitted. The Company elected to early adopt this guidance in the fourth quarter of 2016. The adoption of this ASU decreased the Company's income tax expense by $14 million in 2016 and increased diluted shares outstanding by approximately one million shares. Excess tax benefits related to stock compensation are now presented as cash flows from operating activities rather than as cash flows from financing activities, this aspect of the guidance has been adopted prospectively. In connection with the adoption, the Company has elected to account for forfeitures as they occur.

In May 2015, the FASB issued an ASU which expands the disclosure requirements for insurance companies that issue short-duration contracts. The new standard will increase the level of disclosure around the Company's Medical Claims Liability to include the following: claims development by year; claim frequency; a rollforward of the claims liability; and a description of methods and assumptions used for determining the liability. It is effective for annual periods beginning after December 15, 2015 and interim periods beginning after December 15, 2016. The Company has adopted this guidance in the current fiscal year.

Recent Accounting Guidance Not Yet Adopted

In January 2017, the FASB issued an ASU simplifying the test for goodwill impairment. The amendments in this ASU eliminate Step 2 from the goodwill impairment test. Thus, an entity will no longer be required to compare the implied fair value of a reporting unit’s goodwill to its carrying amount. Instead, under the new guidance, an entity should perform the goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount and should recognize an impairment charge for the amount by which the carrying amount exceeds the fair value. The impairment charge should be limited to the total amount of goodwill allocated to that reporting unit. Under the new guidance, an entity still has the option to first perform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary. The new standard is effective for an entity’s annual or interim goodwill impairment tests in fiscal years beginning after December 15, 2019. Early adoption is permitted, including adoption in an interim period. The Company is currently evaluating the effect of the new goodwill impairment guidance.

In November 2016, the FASB issued an ASU clarifying the classification and presentation of changes in restricted cash on the statement of cash flows. The amendments in this ASU require that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and restricted cash. Therefore, amounts generally described as restricted cash should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. The new standard is effective for annual periods beginning after December 15, 2017, including interim periods within those annual reporting periods. Early adoption is permitted, including adoption in an interim period. The Company is currently evaluating the effect of the new statement of cash flows guidance.

In August 2016, the FASB issued an ASU which clarifies how entities should classify certain cash receipts and cash payments on the statement of cash flows. The new guidance also clarifies how the predominance principle should be applied when cash receipts and cash payments have aspects of more than one class of cash flows. The new standard is effective for annual periods beginning after December 15, 2017, including interim periods within those annual reporting periods. Early adoption is permitted. The Company is currently evaluating the effect of the new statement of cash flows guidance.

In February 2016, the FASB issued an ASU which introduces a lessee model that requires the majority of leases to be recognized on the balance sheet. The new standard also aligns many of the underlying principles of the new lessor model with those in Accounting Standards Codification 606, the FASB's new revenue recognition standard, and addresses other concerns related to the current lessee model. The standard also requires lessors to increase the transparency of their exposure to changes in value of their residual assets and how they manage that exposure. It is effective for annual and interim periods beginning after December 15, 2018. Early adoption is permitted. The Company is currently evaluating the effect of the new lease guidance.

78

In May 2014, the FASB issued an ASU which supersedes existing revenue recognition standards with a single model unless those contracts are within the scope of other standards (e.g., an insurance entity's insurance contracts). Under the new standard, recognition of revenue occurs when a customer obtains control of promised goods or services in an amount that reflects the consideration which the entity expects to receive in exchange for those goods or services. In addition, the standard requires disclosure of the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. The new effective date is for annual and interim periods beginning after December 15, 2017. Early adoption is permitted. The Company is currently evaluating the effect of the new revenue recognition guidance. The majority of the Company's revenues are derived from insurance contracts and are excluded from the new standard, therefore the new guidance is not expected to have a material impact on the Company's consolidated financial position, results of operations or cash flows. 

The Company has determined that there are no other recently issued accounting pronouncements that will have a material impact on its consolidated financial position, results of operations or cash flows.

3. Health Net

On March 24, 2016, the Company acquired all of the issued and outstanding shares of Health Net, a publicly traded managed care organization that delivers health care services through health plans and government-sponsored managed care plans. The transaction was valued at approximately $5,990 million, including the assumption of $703 million of outstanding debt. The acquisition allows the Company to offer a more comprehensive and scalable portfolio of solutions and provides opportunity for additional growth across the combined company's markets.

The total consideration for the acquisition was $5,287 million, consisting of Centene common shares valued at $3,038 million (based on Centene's stock price of $62.70), $2,247 million in cash, and $2 million related to the fair value adjustment to stock based compensation associated with pre-combination service. Each Health Net share was converted into 0.622 of a validly issued, fully paid, non-assessable share of Centene common stock and $28.25 in cash. In total, 48,449,444 shares of Centene common stock were issued in connection with the transaction. The cash portion of the acquisition consideration was funded through the issuance of long-term debt as further discussed in Note11,Debt. For the year ended December 31, 2016, the Company also recognized acquisition related expenses of $234 million that were recorded in selling, general and administrative (SG&A) expense in the Consolidated Statements of Operations.

The acquisition of Health Net has been accounted for as a business combination using the acquisition method of accounting which requires assets acquired and liabilities assumed to be recognized at fair value as of the acquisition date. The valuation of all the assets acquired and liabilities assumed was finalized in the fourth quarter of 2016.

79

Since the initial allocation of purchase price, the Company made adjustments and reclassifications to the fair value of certain assets and liabilities acquired, including the premium and related receivables, medical claims liability, accrued liabilities, return of premium payable and deferred taxes, resulting in a net increase of $258 million to goodwill. The Company's allocation of the fair value of assets acquired and liabilities assumed as of the acquisition date of March 24, 2016, is as follows ($ in millions):

Assets Acquired and Liabilities Assumed
Cash and cash equivalents	$	956
Premium and related receivables (a)	1,890
Short term investments	74
Other current assets	524
Long term investments	2,037
Restricted deposits	30
Property, software and equipment, net	41
Intangible assets (b)	1,530

Total assets acquired and liabilities assumed	$	5,287

Significant fair value adjustments are noted as follows:

(a) The fair value of premium and related receivables approximated their historical cost, with the exception of the risk corridor receivable associated with the Health Insurance Marketplace. The fair value of the risk corridor receivable was estimated at $9 million.

(b) The identifiable intangible assets acquired are to be measured at fair value as of the completion of the acquisition. The fair value of intangible assets is determined primarily using variations of the "income approach," which is based on the present value of the future after tax cash flows attributable to each identified intangible asset. Other valuation methods, including the market approach and cost approach, were also utilized in estimating the fair value of certain intangible assets. The Company has finalized its fair value of intangibles to be $1,530 million with a weighted average life of 12 years. This final fair value of intangibles is approximately $30 million higher than the preliminary fair value of intangibles and the weighted average life increased by two years, which resulted in an immaterial true-up of intangible amortization recorded during the fourth quarter of 2016. The Company identified intangible assets including purchased contract rights, provider contracts, trade names and developed technology.

(c) Medical claims liability and accounts payable and accrued expenses include $160 million of reserves associated with substance abuse rehabilitation claims primarily related to periods prior to the acquisition date.

(d) Accounts payable and accrued expenses include approximately $253 million related to premium deficiency reserves based on cost trends existing prior to the acquisition date. The premium deficiency reserves are primarily associated with losses in the individual commercial business, largely in California, unfavorable performance in the Arizona commercial business as well as unfavorable performance in the Medicare business primarily in Oregon and Arizona.

80

(e) The deferred tax liabilities are presented net of $365 million of deferred tax assets.

(f) Debt is required to be measured at fair value under the acquisition method of accounting. The fair value of Health Net's $400 million Senior Notes assumed in the acquisition was $418 million. The $18 million increase will be amortized as a reduction to interest expense over the remaining life of the debt. In November 2016, this debt was redeemed as discussed in Note11,Debt.

(g) The acquisition resulted in $3,859 million of goodwill related primarily to buyer specific synergies expected from the acquisition and the assembled workforce of Health Net. This goodwill is not deductible for income tax purposes. The Company assigned $3,317 million of goodwill to the Managed Care segment and $542 million of goodwill to the Specialty Services segment.    

The fair values and weighted average useful lives for identifiable intangible assets acquired are as follows:

	Fair Value		Weighted Average Useful Life (in years)
Purchased contract rights	$	1,095	13
Provider contracts	181		11
Trade names	150		10
Developed technology	104		5
Total intangible assets acquired	$	1,530	12

Statement of Operations

From the acquisition date through December 31, 2016, the Company's Consolidated Statements of Operations include total Health Net revenues of $13,454 million. It is impracticable to determine the effect on net income resulting from the Health Net acquisition for the year ended December 31, 2016, as the Company immediately integrated Health Net into its ongoing operations.

Unaudited Pro Forma Financial Information

The unaudited pro forma total revenues for the year ended December 31, 2016 were $44,280 million. The following table presents supplemental pro forma information for the year ended December 31, 2015 ($ in millions, except per share data).

	December 31, 2015
Total revenues	$	38,826
Net earnings attributable to Centene Corporation	$	245
Diluted earnings per share	$	1.43

The pro forma results do not reflect any anticipated synergies, efficiencies, or other cost savings of the acquisition. Accordingly, the unaudited pro forma financial information is not indicative of the results if the acquisition had been completed on January 1, 2015 and is not a projection of future results. It is impracticable for the Company to determine the pro forma earnings information for the year ended December 31, 2016 due to the nature of obtaining that information as the Company immediately integrated Health Net into its ongoing operations.

The unaudited pro forma financial information reflects the historical results of Centene and Health Net adjusted as if the acquisition had occurred on January 1, 2015, primarily for the following:

• Additional interest income associated with adjusting the amortized cost of Health Net's investment portfolio to fair value.

• Elimination of historical Health Net intangible asset amortization expense and addition of amortization expense based on the current values of identifiable intangible assets.

• Adjustments to premium revenue related to the risk corridor receivables associated with the Health Insurance Marketplace to align with Centene's accounting policies.

81

• Interest expense associated with financing the acquisition and amortization of the fair value adjustment to Health Net's debt.

• Additional stock compensation expense related to the amortization of the fair value increase to Health Net rollover stock awards.

• Increased tax expense due to the assumption that Centene would be subject to the IRS Regulation 162(m)(6) beginning in 2015.

• Elimination of acquisition related costs.

Restructuring Related Charges

In connection with the Health Net acquisition, the Company undertook a restructuring plan as a result of the integration of Health Net's operations into its business, resulting in a reduction in workforce beginning in 2016 and expected to continue through early 2017. The restructuring related costs are classified as SG&A expenses in the Consolidated Statements of Operations. Changes in the restructuring liability for the year ended December 31, 2016 were as follows ($ in millions):

	December 31, 2016
	Employee Termination Costs			Stock Based Compensation			Total
Total accrued restructuring costs as of December 31, 2015	$	—		$	—		$	—
Charges incurred	46			43			89
Paid/settled	(28		)	(43		)	(71		)
Total accrued restructuring costs as of December 31, 2016	$	18		$	—		$	18

For the year ended December 31, 2016, the Company recorded employee termination costs of $46 million and stock based compensation of $43 million in the Managed Care Segment. The Company expects to record a total of approximately $51 million of employee termination costs and $45 million of stock based compensation in connection with the acquisition, the majority of which was expensed in 2016. The remainder is to be incurred in early 2017.

Commitments

In connection with obtaining regulatory approval of the Health Net acquisition from the California Department of Insurance and the California Department of Managed Health Care, the Company committed to certain undertakings (the Undertakings). The Undertakings included, among other items, operational commitments around premiums, dividend restrictions, minimum Risk Based Capital (RBC) levels, local offices, growth, accreditation, HEDIS scores and other quality measures, network adequacy, certifications, investments and capital expenditures. Specifically, the Company agreed to, among other things:

• invest an additional $30 million through the California Organized Investment Network over the five years following completion of the acquisition;

• build a service center in an economically distressed community in California, investing $200 million over 10 years and employing at least 300 people;

• contribute $65 million to improve enrollee health outcomes ($10 million over 10 years), support locally based consumer assistance programs ($5 million over five years) and strengthen the health care delivery system ($50 million over five years), (of which, the present value of $61 million was expensed in the year ended December 31, 2016, and classified as SG&A expenses in the Consolidated Statements of Operations); and

• invest $75 million of its investment portfolio in vehicles supporting California’s health care infrastructure.

4. Acquisitions and Noncontrolling Interest

Acquisitions

Health Net. On March 24, 2016, the Company acquired all of the issued and outstanding shares of Health Net, a publicly traded managed care organization that delivers health care services through health plans and government-sponsored managed care plans. See Note 3, Health Net, for further discussion on the acquisition.

82

Agate Resources, Inc. In September2015, the Company completed the acquisition of Agate Resources, Inc. (Agate) for $114 million. Agate is a diversified holding company that offers primarily Medicaid and other healthcare products and services to Oregon residents. The fair value of consideration of $114 million consists of initial cash consideration of $93 million, the present value of future cash payments of $12 million to be paid out over a three year period, and the fair value of estimated contingent consideration of $9 million. A portion of the contingent consideration is based on the achievement of underwriting targets and is being paid in cash over a three year period; the remainder is based on the net proceeds of a retrospective rate adjustment, which was settled in 2016.

The Company's allocation of fair value resulted in goodwill of $42 million and other identifiable intangible assets of $39 million. The goodwill is not deductible for income tax purposes. The acquisition is recorded in the Managed Care segment.

Noncontrolling Interest

The Company has consolidated subsidiaries where it maintains less than 100% ownership. The Company’s ownership interest for each subsidiary as of December 31, are as follows:

	2016		2015		2014
Celtic Insurance Company	100	%	75	%	100	%
Cenpatico Integrated Care	80	%	80	%	80	%
Centurion	51	%	51	%	51	%
Home State Health Plan	95	%	95	%	95	%
The Practice (Group) Limited (TPG) (1)	75	%	49	%	49	%
U.S. Medical Management	68	%	68	%	68	%

(1)    In 2016, the Company purchased a controlling interest in TPG for $8 million.

Net income attributable to Centene Corporation and transfers from (to) noncontrolling interest entities are as follows ($ in millions):

	Year Ended December 31,
	2016		2015		2014
Net earnings attributable to Centene Corporation	$	559	$	356	$	268
Transfers from (to) the noncontrolling interest:

Net transfers from (to) noncontrolling interest	2		12		(9		)
Changes from net earnings attributable to Centene Corporation and net transfers from (to) the noncontrolling interest	$	561	$	368	$	259

Redeemable Noncontrolling Interest

As a result of put option agreements, noncontrolling interest is considered redeemable and is classified in the Redeemable Noncontrolling Interest section of the Consolidated Balance Sheets. Noncontrolling interest is initially measured at fair value using the binomial lattice model as of the acquisition date. The Company has elected to accrete changes in the redemption value through additional paid-in capital over the period from the date of issuance to the earliest redemption date following the effective interest method.

83

A reconciliation of the changes in the Redeemable Noncontrolling Interest is as follows ($ in millions):

Balance, December 31, 2015	$	156
Noncontrolling interest related to TPG acquisition	3
Noncontrolling interest repurchased related to Celtic Insurance Company	(12		)
Net losses attributable to noncontrolling interest	(2		)
Balance, December 31, 2016	$	145

Pro forma disclosures related to the acquisitions other than Health Net (see Note 3, Health Net) have been excluded as they were deemed to be immaterial.

5. Short term and Long term Investments, Restricted Deposits

Short term and long term investments and restricted deposits by investment type consist of the following ($ in millions):

	December 31, 2016									December 31, 2015
	Amortized Cost		Gross Unrealized Gains		Gross Unrealized Losses			Fair Value		Amortized Cost		Gross Unrealized Gains		Gross Unrealized Losses			Fair Value

Total	$	5,233	$	15	$	(60	)	$	5,188	$	2,225	$	5	$	(12	)	$	2,218

The Company’s investments are classified as available-for-sale with the exception of life insurance contracts and certain cost and equity method investments. The Company’s investment policies are designed to provide liquidity, preserve capital and maximize total return on invested assets with the focus on high credit quality securities. The Company limits the size of investment in any single issuer other than U.S. treasury securities and obligations of U.S. government corporations and agencies. As of December 31, 2016, 95% of the Company’s investments in rated securities carry an investment grade rating by S&P and Moody’s. At December 31, 2016, the Company held certificates of deposit, life insurance contracts and cost and equity method investments which did not carry a credit rating.

The Company's residential mortgage-backed securities are primarily issued by the Federal National Mortgage Association, Government National Mortgage Association or Federal Home Loan Mortgage Corporation, which carry implicit or explicit guarantees of the U.S. government. The Company's commercial mortgage-backed securities are primarily senior tranches with a weighted average rating of AA+ and a weighted average duration of 3.7 years at December 31, 2016.

In January 2016, the Company completed a 19% investment in a data analytics business, and as a result, issued the selling stockholders 1.1 million shares of Centene common stock, valued at $68 million. The investment is being accounted for using the equity method of accounting due to the Company's significant influence of the business.

84

The fair value of available-for-sale investments with gross unrealized losses by investment type and length of time that individual securities have been in a continuous unrealized loss position were as follows ($ in millions):

	December 31, 2016										December 31, 2015
	Less Than 12 Months					12 Months or More					Less Than 12 Months					12 Months or More
	Unrealized Losses			Fair Value		Unrealized Losses			Fair Value		Unrealized Losses			Fair Value		Unrealized Losses			Fair Value
U.S. Treasury securities and obligations of U.S. government corporations and agencies	$	(1	)	$	215	$	—		$	2	$	(2	)	$	294	$	—		$	14
Corporate securities	(12		)	1,020		(1		)	39		(6		)	561		(2		)	41
Municipal securities	(35		)	1,423		—			30		(1		)	208		—			5
Asset backed securities	(1		)	101		—			18		(1		)	121		—			8
Residential mortgage backed securities	(5		)	188		—			—		—			30		—			—
Commercial mortgage backed securities	(5		)	271		—			—		—			34		—			—
Total	$	(59	)	$	3,218	$	(1	)	$	89	$	(10	)	$	1,248	$	(2	)	$	68

As of December 31, 2016, the gross unrealized losses were generated from 1,881 positions out of a total of 2,845 positions. The change in fair value of fixed income securities is primarily a result of movement in interest rates subsequent to the purchase of the security.

For each security in an unrealized loss position, the Company assesses whether it intends to sell the security or if it is more likely than not the Company will be required to sell the security before recovery of the amortized cost basis for reasons such as liquidity, contractual or regulatory purposes. If the security meets this criterion, the decline in fair value is other-than-temporary and is recorded in earnings. The Company does not intend to sell these securities prior to maturity and it is not likely that the Company will be required to sell these securities prior to maturity; therefore, there is no indication of other-than-temporary impairment for these securities.

During the years ended December 31, 2016, 2015 and 2014, the company recognized $5 million, $8 million and $6 million, respectively, of income from equity method investments.

The contractual maturities of short term and long term investments and restricted deposits are as follows ($ in millions):

	December 31, 2016								December 31, 2015
	Investments				Restricted Deposits				Investments				Restricted Deposits
	Amortized Cost		Fair Value		Amortized Cost		Fair Value		Amortized Cost		Fair Value		Amortized Cost		Fair Value
One year or less	$	500	$	500	$	91	$	91	$	176	$	176	$	93	$	93
One year through five years	1,982		1,974		47		47		1,662		1,654		22		22
Five years through ten years	1,101		1,089		—		—		267		268		—		—
Greater than ten years	633		617		—		—		5		5		—		—
Asset-backed securities	879		870		—		—		—		—		—		—
Total	$	5,095	$	5,050	$	138	$	138	$	2,110	$	2,103	$	115	$	115

Actual maturities may differ from contractual maturities due to call or prepayment options. Cost and equity method investments and life insurance contracts are included in the five years through ten years category. The Company has an option to redeem at amortized cost substantially all of the securities included in the greater than ten years category listed above.

85

The Company continuously monitors investments for other-than-temporary impairment. Certain investments have experienced a decline in fair value due to changes in credit quality, market interest rates and/or general economic conditions. The Company recognizes an impairment loss for cost and equity method investments when evidence demonstrates that it is other-than-temporarily impaired. Evidence of a loss in value that is other-than-temporary may include the absence of an ability to recover the carrying amount of the investment or the inability of the investee to sustain a level of earnings that would justify the carrying amount of the investment.

6. Fair Value Measurements

Assets and liabilities recorded at fair value in the Consolidated Balance Sheets are categorized based upon observable or unobservable inputs used to estimate fair value. Level inputs are as follows:

Level Input:	Input Definition:
Level I	Inputs are unadjusted, quoted prices for identical assets or liabilities in active markets at the measurement date.
Level II	Inputs other than quoted prices included in Level I that are observable for the asset or liability through corroboration with market data at the measurement date.
Level III	Unobservable inputs that reflect management’s best estimate of what market participants would use in pricing the asset or liability at the measurement date.

The following table summarizes fair value measurements by level at December 31, 2016, for assets and liabilities measured at fair value on a recurring basis ($ in millions):

The Company periodically transfers U.S. Treasury securities and obligations of U.S. government corporations and agencies between Level I and Level II fair value measurements dependent upon the level of trading activity for the specific securities at the measurement date. The Company’s policy regarding the timing of transfers between Level I and Level II is to measure and record the transfers at the end of the reporting period. At December 31, 2016, there were $1 million of transfers from Level I to Level II and $45 million of transfers from Level II to Level I. The Company utilizes matrix pricing services to estimate fair value for securities which are not actively traded on the measurement date. The Company designates these securities as Level II fair value measurements. The aggregate carrying amount of the Company’s life insurance contracts and other non-majority owned investments, which approximates fair value, was $279 million and $87 million as of December 31, 2016 and December 31, 2015, respectively.

Reinsurance recoverables related to medical claims are included in premium and related receivables. Changes in estimates of incurred claims for prior years are primarily attributable to reserving under moderately adverse conditions. Additionally, as a result of minimum HBR and other return of premium programs, approximately $39 million, $47 million, and $26 million of the “Incurred related to: Prior years” was recorded as a reduction to premium revenues in 2016, 2015 and 2014, respectively. Further, claims processing initiatives yielded increased claim payment recoveries and coordination of benefits related to prior year dates of service. Changes in medical utilization and cost trends and the effect of medical management initiatives may also contribute to changes in medical claim liability estimates. While the Company has evidence that medical management initiatives are effective on a case by case basis, medical management initiatives primarily focus on events and behaviors prior to the incurrence of the medical event and generation of a claim. Accordingly, any change in behavior, leveling of care, or coordination of treatment occurs prior to claim generation and as a result, the costs prior to the medical management initiative are not known by the Company. Additionally, certain medical management initiatives are focused on member and provider education with the intent of influencing behavior to appropriately align the medical services provided with the member's acuity. In these cases, determining whether the medical management initiative changed the behavior cannot be determined. Because of the complexity of its business, the number of states in which it operates, and the volume of claims that it processes, the Company is unable to practically quantify the impact of these initiatives on its changes in estimates of IBNR.

The Company periodically reviews actual and anticipated experience compared to the assumptions used to establish medical costs. The Company establishes premium deficiency reserves if actual and anticipated experience indicates that existing policy liabilities together with the present value of future gross premiums will not be sufficient to cover the present value of future benefits, settlement and maintenance costs.

10. Affordable Care Act

The Affordable Care Act (ACA) established risk spreading premium stabilization programs effective January 1, 2014. These programs, commonly referred to as the “three Rs,” include a permanent risk adjustment program, a transitional reinsurance program, and a temporary risk corridor program. Additionally, the ACA established a minimum annual MLR and cost sharing reductions. Each of the three R programs are taken into consideration to determine if the Company’s estimated annual medical costs are less than the minimum loss ratio and require an adjustment to Premium revenue to meet the minimum MLR.

During 2016, the Company recognized a $51 million net pre-tax benefit related to the reconciliation of 2015 risk adjustment and reinsurance programs.

The Company's receivables (payables) for each of these programs are as follows at each year ended ($ in millions):

Senior Notes

In December 2016, the Company redeemed the outstanding principal balance on the $400 million 6.375% Senior Notes, due June 1, 2017, plus applicable premium for early redemption and accrued and unpaid interest to the redemption date, for cash totaling $411 million. The Company recognized a loss on extinguishment of debt of $3 million on the redemption of these notes.

In November 2016, the Company redeemed the outstanding principal balance on the $425 million 5.75% Senior Notes due June 1, 2017, plus applicable premium for early redemption and accrued and unpaid interest to the redemption date, for cash totaling $447 million. The Company recognized a loss on extinguishment of debt of $10 million on the redemption of these notes. The Company also recognized a gain of $2 million on the termination of the $250 million interest rate swap agreement associated with these notes.

In November 2016, the Company issued $1,200 million in aggregate principal amount of 4.75% Senior Notes due 2025 ($1,200 million Notes). The Company used the net proceeds of the offering to redeem its 5.75% Senior Notes due 2017 and Health Net Inc.'s 6.375% Senior Notes due 2017, to repay amounts outstanding under its Revolving Credit Facility, to pay related fees and expenses and for general corporate purposes.

In June 2016, the Company issued an additional $500 million in aggregate principal amount of 4.75% Senior Notes due 2022 ($500 Million Add-on Notes) at a premium to yield of 4.41%. The $500 Million Add-on Notes were offered as additional debt securities under the indenture governing the $500 million in aggregate principal amount of 4.75% Senior Notes issued in April 2014. The Company used the net proceeds of the offering to repay amounts outstanding under its Revolving Credit Facility and to pay offering related fees and expenses.

In February 2016, a wholly owned unrestricted subsidiary of the Company (Escrow Issuer) issued $1,400 million in aggregate principal amount of 5.625% Senior Notes ($1,400 Million Notes) at par due 2021 and $1,000 million in aggregate principal amount of 6.125% Senior Notes ($1,000 Million Notes) at par due 2024. In July 2016, the Company completed an exchange offer, whereby it offered to exchange all of the outstanding $1,400 Million Notes and the $1,000 Million Notes for identical securities that have been registered under the Securities Act of 1933. The Company used the net proceeds of the offering, together with borrowings under the Company's new $1,000 million revolving credit facility and cash on hand, primarily to fund the cash consideration for the Health Net acquisition, and to pay acquisition and offering related fees and expenses.

93

In connection with the February 2016 issuance, the Company entered into interest rate swap agreements for notional amounts of $600 million and $1,000 million, at floating rates of interest based on the three month LIBOR plus 4.22% and the three month LIBOR plus 4.44%, respectively. Gains and losses due to changes in the fair value of the interest rate swaps completely offset changes in the fair value of the hedged portion of the underlying debt and are recorded as an adjustment to the $1,400 Million Notes and $1,000 Million Notes.

In connection with the closing of the Health Net acquisition, the Company assumed the $400 million in aggregate principal amount of Health Net's 6.375% Senior Notes due 2017, recorded at acquisition date fair value of $418 million. These Senior Notes were redeemed in December 2016.

In January 2015, the Company issued an additional $200 million of 4.75% Senior Notes ($200 Million Add-on Notes) at par. The $200 Million Add-on Notes were offered as additional debt securities under the indenture governing the $300 million of 4.75% Senior Notes issued in April 2014. In connection with the January 2015 issuance, the Company entered into interest rate swap agreements for a notional amount of $200 million at a floating rate of interest based on the three month LIBOR plus 2.88%. Gains and losses due to changes in the fair value of the interest rate swap completely offset changes in the fair value of the hedged portion of the underlying debt and are recorded as an adjustment to the $200 Million Add-on Notes.

The indentures governing the $1,400 Million Notes, the $1,000 million of 4.75% Senior Notes due 2022, the $1,000 Million Notes and the $1,200 Million Notes contain non-financial and financial covenants of Centene Corporation, including requirements of a minimum fixed charge coverage ratio. At December 31, 2016, the Company was in compliance with all covenants.

Interest Rate Swaps

The Company uses interest rate swap agreements to convert a portion of its interest rate exposure from fixed rates to floating rates to more closely align interest expense with interest income received on its cash equivalent and variable rate investment balances. The Company has $2,100 million of notional amount of interest rate swap agreements consisting of:

• $600 million expiring on February 15, 2021;

• $500 million expiring on May 15, 2022; and,

• $1,000 million expiring on February 15, 2024.

Under the Swap Agreements, the Company receives a fixed rate of interest and pays an average variable rate of the three month LIBOR plus 3.92% adjusted quarterly. At December 31, 2016, the weighted average rate was 4.83%.

The Swap Agreements are formally designated and qualify as fair value hedges and are recorded at fair value in the Consolidated Balance Sheets in other assets and/or other liabilities. Gains and losses due to changes in fair value of the interest rate swap agreements completely offset changes in the fair value of the hedged portion of the underlying debt. Therefore, no gain or loss has been recognized due to hedge ineffectiveness. Offsetting changes in fair value of both the interest rate swaps and the hedged portion of the underlying debt both were recognized in interest expense in the Consolidated Statement of Operations. The Company does not hold or issue any derivative instrument for trading or speculative purposes.

The fair values of the Swap Agreements as of December 31, 2016 were assets of $4 million and liabilities of $62 million, and are included in other long term assets and other long term liabilities, respectively in the Consolidated Balance Sheet. The fair value of the Swap Agreements as of December 31, 2015 were assets of $11 million and liabilities of $2 million, and are included in other long term assets and other long term liabilities, respectively in the Consolidated Balance Sheet. The fair value of the Swap Agreements excludes accrued interest and takes into consideration current interest rates and current likelihood of the swap counterparties' compliance with its contractual obligations.

Revolving Credit Agreement

In connection with the closing of the Health Net acquisition in March 2016, the Company's existing unsecured $500 million revolving credit facility was terminated and simultaneously replaced with a new $1,000 million unsecured revolving credit facility. Borrowings under the agreement bear interest based upon LIBOR rates, the Federal Funds Rate or the Prime Rate. The agreement has a maturity date of March 24, 2021. As of December 31, 2016, the Company had $100 million of borrowings outstanding under the agreement with a weighted average interest rate of 4.5%, and the Company was in compliance with all covenants.

94

The revolving credit facility contains both non-financial and financial covenants, including requirements of minimum fixed charge coverage ratios and maximum debt-to-EBITDA ratios. The Company is required to not exceed a maximum debt-to-EBITDA ratio of 3.5 to 1.0 prior to December 31, 2016 and 3.0 to 1.0 on and subsequent to December 31, 2016. As of December 31, 2016, there were no limitations on the availability under the revolving credit agreement as a result of the debt-to-EBITDA ratio.

Also, upon the closing of the Health Net acquisition, the Company assumed, fully repaid $285 million in outstanding borrowings under, and terminated the existing Health Net revolving credit facility.

Mortgage Notes Payable

The Company has a non-recourse mortgage note of $64 million at December 31, 2016 collateralized by its corporate headquarters building. The mortgage note is due January 1, 2021 and bears a 5.14% interest rate. The collateralized property had a net book value of $173 million at December 31, 2016.

Letters of Credit & Surety Bonds

The Company had outstanding letters of credit of $71 million as of December 31, 2016, which were not part of the revolving credit facility. The Company also had letters of credit for $45 million (valued at December 31, 2016 conversion rate), or €42 million, representing its proportional share of the letters of credit issued to support Ribera Salud's outstanding debt, which are a part of the revolving credit facility. Collectively, the letters of credit bore interest at 1.42% as of December 31, 2016. The Company had outstanding surety bonds of $365 million as of December 31, 2016.

Aggregate maturities for the Company's debt are as follows ($ in millions):

2017	$	4
2018	4
2019	16
2020	4
2021	1,404
Thereafter	3,350
Total	$	4,782

The fair value of outstanding debt was approximately $4,676 million and $1,239 million at December 31, 2016 and 2015, respectively.

12. Stockholders' Equity

The Company has 10,000,000 authorized shares of preferred stock at $.001 par value. At December 31, 2016, there were no preferred shares outstanding.

The Company's Board of Directors has authorized a stock repurchase program for up to 8,000,000 shares of the Company's common stock from time to time on the open market or through privately negotiated transactions. No duration has been placed on the repurchase program. The Company has 3,335,448 available shares remaining under the program for repurchases as of December 31, 2016. The Company reserves the right to discontinue the repurchase program at any time. During the year ended December 31, 2016, the Company did not repurchase any shares through this publicly announced program.

As a component of the employee stock compensation plan, employees can use shares of stock which have vested to satisfy statutory tax withholding obligations. As part of this plan, the Company repurchased 1,078,335 shares at an aggregate cost of $63 million in 2016 and 918,628 shares at an aggregate cost of $53 million in 2015. These shares are included in the Company's treasury stock.

In March 2016, the Company issued 48,449,444 shares of Centene stock, with a fair value of approximately $3,038 million.

95

In January 2016, the Company completed a 19% investment in a data analytics business and issued 1,144,462 shares of Centene common stock to the selling stockholders. The investment is being accounted for using the equity method of accounting, due to the Company's significant influence on the business.

13. Statutory Capital Requirements and Dividend Restrictions

Various state laws require Centene's regulated subsidiaries to maintain minimum capital levels specified by each state and restrict the amount of dividends that may be paid without prior regulatory approval. At December 31, 2016 and 2015, Centene's subsidiaries, including Kentucky Spirit, had aggregate statutory capital and surplus of $4,529 million and $2,284 million, respectively, compared with the required minimum aggregate statutory capital and surplus of $2,259 million and $1,195 million, respectively. As of December 31, 2016, the amount of capital and surplus or net worth that was unavailable for the payment of dividends or return of capital to the Company was $2,259 million in the aggregate.

Net deferred tax assets (liabilities)	$	(303	)	$	87

Valuation allowances are provided when it is considered more likely than not that deferred tax assets will not be realized. The valuation allowances primarily relate to future tax benefits on certain federal, state and foreign net operating loss and tax credit carryforwards. The $75 million increase in valuation allowance primarily relates to acquired federal and state net operating loss carryforwards from the Health Net transaction. 

Federal net operating loss carryforwards of $59 million expire beginning in 2020 through 2036; state net operating loss and tax credit carryforwards of $37 million expire beginning in 2017 through 2036. Substantially all of the non-U.S. tax loss carryforwards have indefinite carryforward periods.

The Company maintains a reserve for uncertain tax positions that may be challenged by a tax authority. A rollforward of the beginning and ending amount of uncertain tax positions, exclusive of related interest and penalties, is as follows:

	Year Ended December 31,
	2016			2015
Gross unrecognized tax benefits, beginning of period	$	5		$	4
Gross increases:
Current year tax positions	6			1
Acquired reserves	93			—
Gross decreases:
Prior year tax positions	(1		)	—
Statute of limitation lapses	(1		)	—
Gross unrecognized tax benefits, end of period	$	102		$	5

Uncertain tax positions increased $93 million due to the acquisition of Health Net. As of December 31, 2016, $87 million of unrecognized tax benefits could impact our effective tax rate in future periods, if recognized. The Company believes it is reasonably possible that its liability for unrecognized tax benefits will decrease in the next twelve months by $5 million as a result of audit settlements and the expiration of statutes of limitations in certain major jurisdictions.

The table above excludes interest, net of related tax benefits, which is treated as income tax expense (benefit) under our accounting policy. For the year ended December 31, 2016, the Company recognized net interest expense and penalties related

97

to uncertain positions of $1 million. The Company had $5 million and $1 million of accrued interest and penalties for uncertain tax positions as of December 31, 2016 and 2015, respectively.

The company files tax returns for federal as well as numerous state tax jurisdictions. As of December 31, 2016, Health Net is under federal examination for tax years 2011 through 2013. Additionally, tax years subject to federal examination for both Centene and Health Net are 2014 through 2016.

In September 2014, the Internal Revenue Service issued final regulations related to the compensation deduction limitation applicable to certain health insurance issuers. The new regulations provided additional information regarding the definition of a health insurance issuer. As a result of this change in regulation, tax benefits of $14 million related to 2013 were recorded during the 2014 period. The Company finalized the 2013 federal audit in the third quarter of 2016 and sustained its compensation deduction limitation position.

As of December 31, 2016 and 2015, the Company had $12 million and $8 million, respectively, of undistributed earnings from non-U.S. subsidiaries that are intended to be reinvested in non-U.S. operations. Because these earnings are considered permanently reinvested, no U.S. tax provision has been accrued related to the repatriation of these earnings. The amount of U.S. tax that would be payable on the eventual remittance of such earnings is not material to the Company’s financial statements.

15. Stock Incentive Plans

The Company's stock incentive plans allow for the granting of restricted stock or restricted stock unit awards and options to purchase common stock. Both incentive stock options and nonqualified stock options can be awarded under the plans. No option will be exercisable for longer than ten years after the date of grant. The plans have 6,224,268 shares available for future awards. However, 5,376,101 are legacy Health Net shares and based on the terms of the Health Net acquisition, these shares are only available for awards to legacy Health Net employees and new Centene employees. Compensation expense for stock options and restricted stock unit awards is recognized on a straight-line basis over the vesting period, generally three to five years for stock options and one to 10 years for restricted stock or restricted stock unit awards. Certain restricted stock unit awards contain performance-based as well as service-based provisions. Certain awards provide for accelerated vesting if there is a change in control as defined in the plans. In addition, the Company incorporated retirement provisions in our stock-based compensation agreements beginning in 2016. The total compensation cost that has been charged against income for the stock incentive plans was $148 million, $71 million and $48 million for the years ended December 31, 2016, 2015 and 2014, respectively. The Company adopted ASU 2016-09 during the fourth quarter of 2016, effective prospectively as of the beginning of the 2016 fiscal year. As a result, excess tax benefits are now recorded in income tax expense in the period in which the exercise or vesting occurs. The total income tax benefit recognized in the income statement for stock-based compensation arrangements was $67 million, $24 million and $17 million for the years ended December 31, 2016, 2015 and 2014, respectively. In connection with the adoption of the new standard, we have also elected to recognize forfeitures as they occur.

Option activity for the year ended December 31, 2016 is summarized below:

	Shares		Weighted Average Exercise Price		Aggregate Intrinsic Value ($ in millions)		Weighted Average Remaining Contractual Term
Outstanding as of December 31, 2015	677,408		$	11.88

The fair value of each option grant is estimated on the date of the grant using the Black-Scholes option-pricing model with the following weighted-average assumptions:

	Year Ended December 31,
	2016	2015 (1)	2014 (1)
Expected life (in years)	4.8	—	—
Risk-free interest rate	1.6%	—	—
Expected volatility	39.0%	—	—
Expected dividend yield	—	—	—
(1) No options were awarded in the years ended December 31, 2015 and 2014.

For options granted in the year ended December 31, 2016, the Company used a projected expected life for each award granted based on historical experience of employees' exercise behavior. The expected volatility is primarily based on historical volatility levels. The risk-free interest rates are based on the implied yield currently available on U.S. Treasury instruments with a remaining term equal to the expected life.

The total fair value of restricted stock and restricted stock units vested during the years ended December 31, 2016, 2015 and 2014, was $147 million, $112 million and $82 million, respectively.

As of December 31, 2016, there was $233 million of total unrecognized compensation cost related to non-vested share-based compensation arrangements granted under the plans; that cost is expected to be recognized over a weighted-average period of 2.4 years.

The Company maintains an employee stock purchase plan and issued 118,293 shares, 86,819 shares, and 76,088 shares in 2016, 2015 and 2014, respectively.

16. Retirement Plan

Centene has a defined contribution plan which covers substantially all employees who are at least twenty-one years of age. Under the plan, eligible employees may contribute a percentage of their base salary, subject to certain limitations. Centene may elect to match a portion of the employee's contribution. Company expense related to matching contributions to the plan was $37 million, $19 million and $12 million during the years ended December 31, 2016, 2015 and 2014, respectively.

17. Commitments

Centene and its subsidiaries lease office facilities and various equipment under non-cancelable operating leases which may contain escalation provisions. The rental expense related to these leases is recorded on a straight-line basis over the lease term, including rent holidays. Tenant improvement allowances are recorded as a liability and amortized against rent expense over the term of the lease. Rent expense was $137 million, $64 million and $46 million for the years ended December 31, 2016, 2015 and 2014, respectively. Annual non-cancelable minimum lease payments over the next five years and thereafter are as follows ($ in millions):

In connection with obtaining regulatory approval of the Health Net acquisition from the California Department of Insurance and the California Department of Managed Health Care, the Company committed to certain undertakings. See Note 3, Health Net for further details.

18. Contingencies

Overview

The Company records reserves and accrues costs for certain legal proceedings and regulatory matters to the extent that it determines an unfavorable outcome is probable and the amount of the loss can be reasonably estimated. While such reserves and accrued costs reflect the Company's best estimate of the probable loss for such matters, the recorded amounts may differ materially from the actual amount of any such losses. In some cases, no estimate of the possible loss or range of loss in excess of amounts accrued, if any, can be made because of the inherently unpredictable nature of legal and regulatory proceedings, which may be exacerbated by various factors, including but not limited to, they may involve indeterminate claims for monetary damages or may involve fines, penalties or punitive damages; present novel legal theories or legal uncertainties; involve disputed facts; represent a shift in regulatory policy; involve a large number of parties, claimants or regulatory bodies; are in the early stages of the proceedings; involve a number of separate proceedings and/or a wide range of potential outcomes; or result in a change of business practices.

As of the date of this report, amounts accrued for legal proceedings and regulatory matters were not material. However, it is possible that in a particular quarter or annual period the Company’s financial condition, results of operations, cash flow and/or liquidity could be materially adversely affected by an ultimate unfavorable resolution of or development in legal and/or regulatory proceedings, including as described below. Except for the proceedings discussed below, the Company believes that the ultimate outcome of any of the regulatory and legal proceedings that are currently pending against it should not have a material adverse effect on financial condition, results of operations, cash flow or liquidity.

Kentucky

On July 5, 2013, the Company's subsidiary, Kentucky Spirit, terminated its contract with the Commonwealth of Kentucky (the Commonwealth). Kentucky Spirit believed it had a contractual right to terminate the contract and filed a lawsuit in Franklin Circuit Court seeking a declaration of this right. In response, the Commonwealth alleged that Kentucky Spirit's exit constituted a material breach of contract. The Commonwealth sought to recover substantial damages and to enforce its rights under Kentucky Spirit's $25 million performance bond. The Commonwealth asserted that the Commonwealth's expenditures due to Kentucky Spirit's departure range from $28 million to $40 million plus interest, and that the associated CMS expenditures range from $92 million to $134 million. Kentucky Spirit disputed the Commonwealth's alleged damages on several grounds. Prior to terminating the contract, Kentucky Spirit filed a legal complaint in April 2013, amended in October 2014, in Franklin Circuit Court seeking damages against the Commonwealth for losses sustained due to the Commonwealth's alleged breaches.

100

On May 26, 2015, the Commonwealth issued a demand for indemnification to its actuarial firm, for "all defense costs, and any resultant monetary awards in favor of Kentucky Spirit, arising from or related to Kentucky Spirit's claims which are predicated upon the alleged omissions and errors in the Data Book and the certified actuarially sound rates." The actuarial firm moved to intervene in the litigation and the Franklin Circuit Court granted that motion on September 8, 2015. Also, on August 19, 2015, the actuarial firm filed a petition seeking a declaratory judgment that it is not liable to the Commonwealth for indemnification related to the claims asserted by Kentucky Spirit against the Commonwealth. On October 5, 2015, the Commonwealth filed an answer to the actuarial firm's petition and asserted counterclaims/cross-claims against the firm.

On November 3, 2016, all parties entered into a settlement agreement with respect to all lawsuits and complaints associated with the aforementioned contract termination. Under the terms of the settlement agreement, Kentucky Spirit received an immaterial cash payment from the Commonwealth's actuarial firm and each party dismissed all claims related to the litigation with prejudice. In addition, the Commonwealth and Kentucky Spirit have agreed that neither party acted in bad faith; that the parties took reasonable positions in light of the applicable contractual language; and that the parties acted in good faith in attempting to address a difficult situation.

California

The Company's California subsidiary, Health Net of California, Inc. (Health Net California), has been named as a defendant in a California taxpayer action filed in Los Angeles County Superior Court, captioned as Michael D. Myers v. State Board of Equalization, et al., Los Angeles Superior Court Case No. BS158655. This action is brought under a California statute that permits an individual taxpayer to sue a governmental agency when the taxpayer believes the agency has failed to enforce governing law. Plaintiff contends that Health Net California, a California licensed Health Care Service Plan (HCSP), is an “insurer” for purposes of taxation despite acknowledging it is not an “insurer” under regulatory law. Under California law, “insurers” must pay a gross premiums tax (GPT), calculated as 2.35% on gross premiums. As a licensed HCSP, Health Net California has paid the California Corporate Franchise Tax (CFT), the tax generally paid by California businesses. Plaintiff contends that Health Net California must pay the GPT rather than the CFT. Plaintiff seeks a writ of mandate directing the California taxing agencies to collect the GPT, and seeks an order requiring Health Net California to pay GPT, interest and penalties for a period dating to eight years prior to the October 20, 2015 filing of the complaint. This lawsuit is being coordinated with similar lawsuits filed against other entities. The Company expects an initial status conference shortly. The Company intends to vigorously defend itself against these claims; however, this matter is subject to many uncertainties, and an adverse outcome in this matter could potentially have a materially adverse impact on our financial position and results of operations.

Federal Securities Class Action

On November 14, 2016, a putative federal securities class action was filed against the Company and certain of its executives in the U.S. District Court for the Central District of California. The plaintiffs in the lawsuit allege that the Company's accounting and related disclosures for certain liabilities acquired in the acquisition of Health Net violated federal securities laws. The Company denies any wrongdoing and is vigorously defending itself against these claims. Nevertheless, this matter is subject to many uncertainties and the Company cannot predict how long this litigation will last or what the ultimate outcome will be, and an adverse outcome in this matter could potentially have a materially adverse impact on our financial position and results of operations.

Civil Investigative Demand

On December 15, 2016, a Civil Investigative Demand (CID) was issued to Health Net by the United States Department of Justice regarding Health Net’s submission of risk adjustment claims to the CMS under Parts C and D of Medicare. The CID may be related to a federal qui tam lawsuit filed under seal in 2011 naming more than a dozen health insurers including Health Net. The lawsuit was recently unsealed when the Department of Justice intervened in the case with respect to one of the insurers (not Health Net). The Company is complying with the CID and will vigorously defend any lawsuits. At this point, it is not possible to determine what level of liability, if any, the Company may face as a result of this matter.

101

Miscellaneous Proceedings

Excluding the matters discussed above, the Company is also routinely subjected to legal and regulatory proceedings in the normal course of business. These matters can include, without limitation:

• periodic compliance and other reviews and investigations by various federal and state regulatory agencies with respect to requirements applicable to the Company's business, including, without limitation, those related to payment of out-of-network claims, submissions to CMS for risk adjustment payments or the False Claims Act, pre-authorization penalties, timely review of grievances and appeals, timely and accurate payment of claims, and the Health Insurance Portability and Accountability Act of 1996;

• litigation arising out of general business activities, such as tax matters, disputes related to health care benefits coverage or reimbursement, putative securities class actions and medical malpractice, privacy, real estate, intellectual property and employment-related claims;

• disputes regarding reinsurance arrangements, claims arising out of the acquisition or divestiture of various assets, class actions and claims relating to the performance of contractual and non-contractual obligations to providers, members, employer groups and others, including, but not limited to, the alleged failure to properly pay claims and challenges to the manner in which the Company processes claims, and claims alleging that the Company has engaged in unfair business practices.

Among other things, these matters may result in awards of damages, fines or penalties, which could be substantial, and/or could require changes to the Company’s business. The Company intends to vigorously defend itself against the miscellaneous legal and regulatory proceedings to which it is currently a party; however, these proceedings are subject to many uncertainties. In some of the cases pending against the Company, substantial non-economic or punitive damages are being sought.

Notes to Condensed Financial Information of Registrant

Note A - Basis of Presentation and Significant Accounting Policies

The parent company only financial statements should be read in conjunction with Centene Corporation's audited consolidated financial statements and the notes to consolidated financial statements included in this Form 10-K.

The parent company's investment in subsidiaries is stated at cost plus equity in undistributed earnings of the subsidiaries. The parent company's share of net income of its unconsolidated subsidiaries is included in income using the equity method of accounting. Certain unrestricted subsidiaries receive monthly management fees from our restricted subsidiaries. The management and service fees received by our unrestricted subsidiaries are associated with all of the functions required to manage the restricted subsidiaries including but not limited to salaries and wages for all personnel, rent, utilities, medical management, provider contracting, compliance, member services, claims processing, information technology, cash management, finance and accounting, and other services. The management fees are based on a percentage of the restricted subsidiaries revenue.

Due to our centralized cash management function, cash flows generated by our unrestricted subsidiaries are transferred to the parent company to the extent required, primarily to repay borrowings on the parent company's revolving credit facility, make acquisitions, fund capital contributions to subsidiaries and fund its operations. During the year ended December 31, 2016, operating cash flows were negatively impacted by the funding of the Health Net acquisition related expenses as well as refinancing the $400 million of Health Net Senior Notes. These Senior Notes were redeemed in December 2016. During the years ended December 31, 2015 and 2014, cash flows received by the parent from unrestricted subsidiaries were $445 million and $341 million, respectively, and were included in cash flows from operating activities.

107

Certain amounts presented in the parent company only financial statements are eliminated in the consolidated financial statements of Centene Corporation. Certain amounts in the parent company only financial statements have been reclassified to conform to the 2016 presentation. These reclassifications have no effect on net earnings or stockholders' equity as previously reported.

Note B - Dividends

During 2016, 2015 and 2014, the Registrant received dividends from its regulated subsidiaries totaling $121 million, $11 million and $50 million, respectively, reflected as investing cash flows.

Item 9. Changes in and Disagreements With Accountants on Accounting and Financial Disclosure

None.

Item 9A. Controls and Procedures

Evaluation of Disclosure Controls and Procedures -Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures as of December 31, 2016. The term “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, means controls and other procedures of a company that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC's rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the company's management, including its principal executive and principal financial officers, as appropriate to allow timely decisions regarding required disclosure. Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Based on the evaluation of our disclosure controls and procedures as of December 31, 2016, our Chief Executive Officer and Chief Financial Officer concluded that, as of such date, our disclosure controls and procedures were effective at the reasonable assurance level.

Management's Report on Internal Control Over Financial Reporting - Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rules 13a-15(f) and 15d-15(f). Under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, we conducted an evaluation of the effectiveness of our internal control over financial reporting based on the framework in InternalControl - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on our evaluation under the framework in Internal Control - Integrated Framework (2013), our management concluded that our internal control over financial reporting was effective at the reasonable assurance level as of December 31, 2016. Our management's assessment of the effectiveness of our internal control over financial reporting as of December 31, 2016 has been audited by KPMG LLP, an independent registered public accounting firm, as stated in their report which is included herein.

Changes in Internal Control Over Financial Reporting - On March 24, 2016, we acquired Health Net, Inc. Management has finalized our evaluation of the internal controls and has integrated Health Net's internal controls over financial reporting with our existing internal controls over financial reporting. This integration has led to changes in the internal controls over financial reporting for us and the acquired Health Net business.

Report of Independent Registered Public Accounting Firm

The Board of Directors and Stockholders

Centene Corporation:

We have audited Centene Corporation’s internal control over financial reporting as of December 31, 2016, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Centene Corporation’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, Centene Corporation maintained, in all material respects, effective internal control over financial reporting as of December 31, 2016, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of Centene Corporation and subsidiaries as of December 31, 2016 and 2015, and the related consolidated statements of operations, comprehensive earnings, stockholders’ equity, and cash flows for each of the years in the three-year period ended December 31, 2016, and our report dated February 20, 2017 expressed an unqualified opinion on those consolidated financial statements.
