Discussion and Analysis of Financial Condition and Results of Operations of our
Annual Report on Form 10-K for the year ended December 31, 2019, filed with the
SEC on February 18, 2020.

                               EXECUTIVE OVERVIEW
General

We are a leading multi-national healthcare enterprise that is committed to helping people live healthier lives. We take a local approach - with local brands and local teams - to provide fully integrated, high-quality, and cost-effective services to government-sponsored and commercial healthcare programs, focusing on under-insured and uninsured individuals.



Results of operations depend on our ability to manage expenses associated with
health benefits (including estimated costs incurred) and selling, general and
administrative (SG&A) costs. We measure operating performance based upon two key
ratios. The health benefits ratio (HBR) represents medical costs as a percentage
of premium revenues, excluding premium tax and health insurer fee revenues that
are separately billed, and reflects the direct relationship between the premiums
received and the medical services provided. The SG&A expense ratio represents
SG&A costs as a percentage of premium and service revenues, excluding premium
tax and health insurer fee revenues that are separately billed.

Our insurance subsidiaries are subject to the Affordable Care Act annual health
insurer fee (HIF), absent a HIF moratorium or repeal. We recognize revenue for
reimbursement of the HIF, including the "gross-up" to reflect the
non-deductibility of the HIF. Collectively, this revenue is recorded as premium
tax and health insurer fee revenue in the Consolidated Statements of Operations.
For certain products, premium taxes, state assessments and the HIF are not
pass-through payments and are recorded as premium revenue and premium tax
expense or health insurer fee expense in the Consolidated Statements of
Operations. A moratorium suspended the HIF for the 2019 calendar year. Due to
the size of the health insurer fee, one of the primary drivers of the
year-over-year variances discussed throughout this section is related to the
reinstatement of the HIF in 2020. The HIF has been repealed beginning in 2021.

WellCare Acquisition



On January 23, 2020, we acquired all of the issued and outstanding shares of
WellCare Health Plans, Inc. (WellCare) (the WellCare Acquisition). The
transaction was valued at $19.6 billion, including the assumption of $1.95
billion of outstanding debt. The WellCare Acquisition brought a
high-quality Medicare platform and further
extended our robust Medicaid offerings. The combination enables us to provide
access to more comprehensive and differentiated solutions across more markets
with a continued focus on affordable, high-quality, culturally-sensitive
healthcare services.

Due to the size of the acquisition, one of the primary drivers of the year-over-year variances discussed throughout this section is related to the acquisition of WellCare.



Magellan Acquisition

In January 2021, we announced that we entered into a definitive merger agreement
under which we will acquire Magellan Health for $95.00 per share in cash for a
total enterprise value of approximately $2.2 billion. The transaction will
broaden and deepen our whole health capabilities and establish a leading
behavioral health platform. The transaction is subject to clearance under the
Hart-Scott Rodino Act, receipt of required state regulatory approvals, the
approval of the definitive merger agreement by Magellan Health's stockholders
and other customary closing conditions. The transaction is not contingent upon
financing. We intend to fund the acquisition primarily through debt financing.
The transaction is expected to close in the second half of 2021.

Acquisitions



We continued to execute on our growth strategy through acquisitions during 2020.
In the fourth quarter of 2020, we acquired PANTHERx and Apixio. PANTHERx is one
of the largest and fastest-growing specialty pharmacies in the United States
                                       42

specializing in orphan drugs and treating rare diseases. PANTHERx and its
management team will continue to operate independently as part of our Envolve
Pharmacy Solutions business unit, a total drug management program that includes
integrated PBM services and specialty pharmacy solutions to millions of members
throughout the United States. Apixio is a healthcare analytics company offering
artificial intelligence technology solutions. With this transaction, we will
continue to digitize the administration of healthcare and accelerate innovation
and modernization across the enterprise. Apixio will remain an operationally
independent entity as part of our Health Care Enterprises group to continue
bringing value to its clients and the industry, while also realizing the
benefits of enhanced scale.

COVID-19 Trends and Uncertainties



The COVID-19 outbreak has created unique and unprecedented challenges. To
support our members, providers, employees and the communities we serve, we have
taken several actions and made numerous investments related to the COVID-19
crisis. We have extended coverage of COVID-19 screening, testing and treatment
services for Medicaid, Medicare and Marketplace members and are waiving all
associated member cost share amounts. We are delivering new critical support to
Safety Net providers, including Federally Qualified Healthcare Centers (FQHCs),
behavioral health providers, and long-term service and support organizations. We
continue to address social determinants of health for vulnerable populations
during the COVID-19 crisis with a commitment to research and investment in
non-medical barriers to achieving quality health outcomes. We developed
initiatives designed to support the disability community affected by the
pandemic. We created a provider support program to assist our network providers
who are seeking benefits from the Small Business Administration (SBA) through
the CARES Act. We established a Medical Reserve Leave policy to support clinical
employees who want to join a medical reserve force and serve their communities
during the COVID-19 pandemic. We are providing additional employee benefits
including waiving cost-sharing for COVID-19 related treatment, emergency paid
sick leave, and one-time payments to employees in a small number of critical
office functions.

We have taken significant steps to support our employees to protect their health
and safety, while also ensuring that our business can continue to operate and
that services continue without disruption. We have implemented our business
continuity plans and have taken actions to support our workforce. We have
transitioned the vast majority of our employees to work from home, allowing
Centene to continue to operate at close to full capacity, while continuing to
maintain our internal control framework. As a result, we have experienced and
expect continued incremental costs due to investments and actions we have
already taken and continued efforts to protect our members, employees and
communities we serve.

The impact on our business in both the short-term and long-term is uncertain.
The outlook for 2021 depends on future developments, including but not limited
to: the length and severity of the outbreak (including new strains, which may be
more contagious, more severe or less responsive to treatment or vaccines), the
effectiveness of containment actions, and the timing around the development of
treatments and distribution of vaccinations. The pandemic and these future
developments have impacted and will continue to affect our membership and
medical utilization. From March 31, 2020 through December 31, 2020, our Medicaid
membership has increased by 1.7 million members. The pandemic also has the
potential to impact the administration of state and federal healthcare programs,
premium rates and risk sharing mechanisms. We continue to have active dialogues
with our state partners.

Medical utilization continues to normalize as elective procedures and other
non-emergent care resume, consistent with our expectations. We have experienced
and continue to expect incremental COVID-19 costs as the outbreak continues to
spread. In addition, the pandemic has widespread economic impact, driving
interest rate decreases and lowering our investment income.

The impact of all these items slightly benefited our 2020 results. We are confident we have the team, systems, expertise and financial strength to continue to effectively navigate this challenging pandemic landscape.

Regulatory Trends and Uncertainties

The United States government, politicians, and healthcare experts continue to
discuss and debate various elements of the United States healthcare model. We
remain focused on the promise of delivering access to high quality, affordable
healthcare to all of our members and believe we are well positioned to meet the
needs of the changing healthcare landscape. We have more than three decades of
experience, spanning seven presidents from both sides of the aisle, in
delivering high-quality healthcare services on behalf of states and the federal
government to under-insured and uninsured families, commercial organizations and
military families. This expertise has allowed us to deliver cost effective
services to our government sponsors and our members. While healthcare experts
maintain focus on personalized healthcare technology, we continue to make
strategic decisions to accelerate development of new software platforms and
analytical capabilities. We continue to believe we have both the capacity and
capability to successfully navigate industry changes to the benefit of our
members, customers and shareholders.

The following items contributed to our revenue and membership growth in 2020:



•Arkansas. In March 2019, our Arkansas subsidiary, Arkansas Total Care, assumed
full-risk on a Medicaid special needs population comprised of people with high
behavioral health needs and individuals with developmental/intellectual
disabilities.

•Correctional. In July 2020, Centurion commenced a two-year contract with the
Kansas Department of Administration to provide healthcare services in the
Department of Corrections' facilities. In April 2020, Centurion began providing
medical services, behavioral healthcare, and substance abuse treatment within
four prisons and six community corrections centers across the state of Delaware.
In July 2019, Centurion began operating under a contract to provide
comprehensive healthcare services to inmates housed in Arizona's state prison
system, and also began operating under a re-awarded contract to continue the
provision of mental and dental health services to the Georgia Department of
                                       44

providing physical and behavioral healthcare services through Florida's
Statewide Medicaid Managed Care Program under its new five year contract which
was implemented for all 11 regions by February 2019.

•Health Insurance Marketplace. In January 2020, we expanded our offerings in the
2020 Health Insurance Marketplace in ten existing markets: Arizona, Florida,
Georgia, Kansas, North Carolina, Ohio, South Carolina, Tennessee, Texas, and
Washington.

•HealthSmart. In May 2019, we acquired HealthSmart, a third party administrator
providing customizable and scalable health plan solutions for self-funded
employers, universities and colleges, and Native American Tribal Enterprises.
Services include plan administration, care management and wellness programs,
network, casualty claim, and pharmacy benefit solutions.

•Illinois. In July 2020, our Illinois subsidiary, Meridian Health Plan of
Illinois, Inc. (Meridian), began serving Medicaid members in Cook County,
Illinois, as a result of a Member Transfer Agreement under which Meridian was
assigned 100% of NextLevel Health Partners, Inc.'s approximately 54,000 members
who access benefits from the Illinois Department of Healthcare and Family
Services' HealthChoice Illinois Program. In February 2020, we began operating in
Illinois under an expanded contract for the Medicaid Managed Care Program. The
expanded contract includes children who are in need through the Department of
Children and Family Services/Youth Care by Illinois Department of Healthcare and
Family Services and Foster Care.

to protested contract awards. Louisiana's state procurement officer overturned
the Louisiana Department of Health's plan to award Medicaid contracts to four
health plans, excluding our Louisiana subsidiary. According to the chief
procurement officer, the state health department failed to follow state law or
its own evaluation and bid guidelines in its award.

Nevada and expanded our footprint in twelve existing markets: Arizona, Arkansas,
California, Georgia, Kansas, Louisiana, Missouri, New Mexico, New York, Ohio,

Inc. and QualChoice Life and Health Insurance Company, Inc. The acquisition
expands our footprint in Arkansas by adding additional members primarily through
commercial products.

•Spain. In December 2019, our Spanish subsidiary, Ribera Salud, acquired 93% of
Hospital Povisa, S.A., a private hospital in the Vigo region of Spain. In June

•WellCare. On January 23, 2020, we completed the WellCare Acquisition. The WellCare Acquisition brought a high-quality Medicare platform and further extended our robust Medicaid offerings. The transaction was valued at $19.6 billion, including the assumption of $1.95 billion of outstanding debt.



•In addition, revenue and membership growth was significantly driven by the
suspension of eligibility redeterminations and increased unemployment levels as
a result of the COVID-19 pandemic, as well as the reinstatement of the health
insurer fee in 2020.

The growth items listed above were partially offset by the following items:

•Effective October 2020, we no longer serve members under the correctional contract in Mississippi.



•In September 2020, our Oregon subsidiary, Trillium Community Health Plan, began
operating under an expanded contract serving as a coordinated care organization
for six counties in the state; however, an additional competitor was added to
Lane County. As a result, our membership decreased.

•Effective August 2020, we no longer serve members under the Military & Family Life Counseling Program contract.

•Effective July 2020, we no longer serve members under the state-wide correctional contract in Vermont.

•In January 2020, in connection with the WellCare Acquisition, we completed the divestiture of certain products in our Illinois health plan, including the Medicaid and Medicare Advantage lines of business.

•Effective December 2019, we no longer serve members under the state-wide correctional contract in New Mexico.



•Beginning in January 2019, Health Net of Arizona, Inc. began discontinuing and
non-renewing all of its Employer Group plans for small and large business groups
in Arizona. The effective date of coverage termination for existing groups is
dependent on remaining renewals; however, coverage is no longer provided to any
group policyholders and/or members as of December 31, 2019.

We expect the following items to contribute to our revenue or future growth potential:

•We expect to realize the full year benefit in 2021 of acquisitions, investments, and business commenced during 2020, as discussed above.



•In January 2021, Centene announced that its Oklahoma subsidiary, Oklahoma
Complete Health, has been selected by the Oklahoma Health Care Authority (OHCA)
for statewide contracts to provide managed care for the SoonerSelect and, on a
sole source basis, SoonerSelect Specialty Children's Plan (SCP) (foster care)
programs. The state expects to commence the SoonerSelect and SoonerSelect SCP
Programs on October 1, 2021.

•In January 2021, we began administering the Buckley Prime Service Area Pilot in the Denver, Colorado area, which is a TRICARE pilot program to value-based payment arrangements not currently an option in the fee-for-service T2017 reimbursement model.



•In January 2021, we announced that we entered into a definitive merger
agreement under which we will acquire Magellan Health for $95.00 per share in
cash for a total enterprise value of approximately $2.2 billion. The transaction
is subject to clearance under the Hart-Scott Rodino Act, receipt of required
state regulatory approvals, the approval of the definitive merger agreement by
Magellan Health's stockholders and other customary closing conditions. The
transaction is expected to close in the second half of 2021.

•In January 2021, we expanded our offerings in the Health Insurance Marketplace.
We expanded our Marketplace product, branded Ambetter, in nearly 400 new
counties across 13 existing states. In addition, Ambetter-branded Marketplace
products is now offered in two new states, New Mexico and Michigan.

•In December 2020, we acquired PANTHERx, one of the largest and fastest-growing specialty pharmacies in the United States specializing in orphan drugs and treating rare diseases.



•In December 2020, we acquired Apixio Inc., a healthcare analytics company
offering artificial intelligence technology solutions. With this transaction, we
will continue to digitize the administration of healthcare and accelerate
innovation
                                       46

and modernization across the enterprise.



•In October 2019, our North Carolina joint venture, Carolina Complete Health,
was awarded an additional service area to provide Medicaid managed care services
in Region 4. With the addition of this new Region, Carolina Complete Health will
provide Medicaid managed care services in three contiguous regions: Region 3, 4
and 5. In February 2019, WellCare was awarded a statewide contract to administer
the state's Medicaid Prepaid Health Plans. The new contracts are expected to
commence in mid-2021.

The future growth items listed above are partially offset by the following items:



•In October 2020, Centers for Medicare and Medicaid Services (CMS) published
updated Medicare Star quality ratings for the 2021 rating year. Approximately
30% of our Medicare members are in a 4 star or above plan for the 2022 bonus
year, compared to 46% for the 2021 bonus year. Our quality bonus and rebates may
be negatively impacted in 2021 and 2022, if we are unable to utilize mitigation
strategies.

•Beginning in 2021, the health insurer fee has been repealed, which will result in a decrease in revenue.



•We expect a decrease in our marketplace membership driven by a reduction in the
state of Florida, resulting from price competition in three highly populated
counties.

•We expect Medicaid eligibility redeterminations to begin on May 1, 2021, resulting in a decrease in membership.

   n.m.: not meaningful



Total revenues increased 49% in the year ended December 31, 2020, over the
corresponding period in 2019, primarily due to the acquisition of WellCare,
growth in the Medicaid and Health Insurance Marketplace businesses, and the
reinstatement of the health insurer fee in 2020. Additionally, the net effect of
the pandemic increased our revenues due to the suspension of Medicaid
eligibility redeterminations. The increase was partially offset by the
divestiture of our Illinois health plan. During the twelve months ended December
31, 2020, we received premium rate adjustments which yielded a net 1% composite
increase across all of our markets.

Operating Expenses

Medical Costs



Results of operations depend on our ability to manage expenses associated with
health benefits and to accurately estimate costs incurred. The HBR represents
medical costs as a percentage of premium revenues, excluding premium tax and
health insurer fee revenues that are separately billed, and reflects the direct
relationship between the premiums received and the medical services provided.

The HBR for the year ended December 31, 2020 was 86.2%, a decrease of 110 basis
points over the comparable period in 2019. The HBR decrease was primarily
attributable to lower medical utilization trends due to the COVID-19 pandemic,
the ACA risk corridor receivable settlement and the reinstatement of the health
insurer fee. The decrease was partially offset by performance in the Health
Insurance Marketplace business, the implementation of retroactive state premium
rate adjustments and risk sharing mechanisms, and higher testing and treatment
costs associated with COVID-19.

Cost of Services



Cost of services increased by $838 million in the year ended December 31, 2020,
compared to the corresponding period in 2019, primarily attributable to
increased volume in our specialty pharmacy business, increased non-specialty
pharmacy sales to our recently divested Illinois health plan, and growth from
acquired businesses.

The cost of service ratio for the year ended December 31, 2020 was 88.2%,
compared to 84.3% in 2019. The increase in the cost of service ratio was driven
by the results of lower revenue from the shared savings programs in our
physician home health business and higher non-specialty pharmacy sales to our
recently divested Illinois health plan, which carries a higher cost of service
ratio.

Selling, General & Administrative Expenses



SG&A increased by $3.3 billion in the year ended December 31, 2020, compared to
the corresponding period in 2019. The SG&A increase was primarily due to the
addition of the WellCare business, expansions, new programs and growth in many
of our states in 2020, and $580 million of acquisition related expense in the
year ended December 31, 2020.

                                       50

--------------------------------------------------------------------------------

Table of Contents



The SG&A expense ratio was 9.5% for the year ended December 31, 2020, compared
to 9.3% for the year ended December 31, 2019. The 2020 SG&A expense ratio
increased due to higher acquisition and integration related expenses primarily
due to the WellCare acquisition, the $275 million charitable contribution to our
foundation and enhanced growth and profitability initiatives for our Medicare
and Health Insurance Marketplace businesses (both as a result of the one-time
ACA risk corridor settlement). These items were partially offset by leveraging
of expenses over higher revenues as a result of the WellCare acquisition.

The Adjusted SG&A expense ratio was 8.9% for the year ended December 31, 2020,
compared to 9.2% for the year ended December 31, 2019. The Adjusted SG&A expense
ratio benefited from leveraging of expenses over higher revenues as a result of
the WellCare acquisition, partially offset by the $275 million charitable
contribution to our foundation and enhanced growth and profitability initiatives
for our Medicare and Health Insurance Marketplace businesses.

Health Insurer Fee Expense

Health insurer fee expense was $1.5 billion for the year ended December 31, 2020. As a result of the health insurer fee moratorium, which suspended the health insurance provider fee for the 2019 calendar year, we did not record health insurer fee expense for the year ended December 31, 2019.

Impairment



During the first quarter of 2020, we recorded $72 million, or $0.10 per diluted
share, of non-cash impairment of our third-party care management software
business. In 2019, we recorded $271 million, or $0.57 per diluted share, of
non-cash goodwill and intangible asset impairment. Substantially all of the 2019
impairment is associated with our USMM physician home health business and was
identified as part of our quarterly review procedures, which included an
analysis of new information related to our shared savings programs, slower than
expected penetration of the physician home health business model into our
Medicaid population, and the related impact to revised forecasts.

Other Income (Expense)

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


                                                     2020       2019
                     Investment and other income   $  480      $ 443

                     Debt extinguishment costs        (61)       (30)
                     Interest expense                (728)      (412)
                     Other income (expense), net   $ (309)     $   1

Investment and other income. Investment and other income increased by $37 million for year ended December 31, 2020 compared to 2019. The increase in investment income in 2020 was due to a $104 million gain related to the divestiture of certain products of our Illinois health plan as part of the previously announced divestiture agreements associated with the WellCare Acquisition as well as overall higher investment balances, partially offset by lower interest rates.



Debt extinguishment costs. In October 2020, we redeemed all of the $1.0 billion
4.75% Senior Notes due 2022 (the 2022 Notes) and the $1.2 billion 5.25% Senior
Notes due 2025 (the 2025 Notes). We recognized a pre-tax loss on extinguishment
of $17 million on the redemption of the 2022 Notes and the 2025 Notes in the
fourth quarter of 2020, including the call premiums and write-off of unamortized
debt issuance costs. In February 2020, we redeemed all of our outstanding $1.0
billion 6.125% Senior Notes, due February 15, 2024 (the 2024 Notes) and
recognized a pre-tax loss on extinguishment of $44 million. The loss includes
the call premium, the write-off of unamortized debt issuance costs and the loss
on the termination of the $1.0 billion interest rate swap associated with the
2024 Notes. In October 2019, we redeemed the outstanding principal balance on
the $1.4 billion 5.625% Senior Notes due February 15, 2021 (the 2021 Notes). We
recognized a pre-tax loss on extinguishment of $30 million on the redemption of
the 2021 Notes, including the call premium, the write-off of unamortized debt
issuance costs and a loss on the termination of the $600 million interest rate
swap agreement associated with the notes.

Interest expense. Interest expense increased by $316 million in the year ended
December 31, 2020, compared to the corresponding period in 2019. The increase is
driven by an increase in borrowings related to the issuance of an additional
$7.0 billion in senior notes in December 2019 to finance the cash consideration
of the WellCare Acquisition as well as the $1.9 billion of WellCare Notes
assumed upon acquisition. The increase was also driven by incremental interest
expense related to our decision to preserve an additional $1.0 billion of
liquidity due to the economic environment created by COVID-19.

Income Tax Expense

For the year ended December 31, 2020, we recorded income tax expense of $979
million on pre-tax earnings of $2.8 billion, or an effective tax rate of 35.3%.
The effective tax rate for the year ended December 31, 2020 reflects the tax
impact associated with the Illinois divestiture and the reinstatement of the
health insurer fee in 2020, partially offset by a favorable tax settlement. For
the year ended December 31, 2019, we recorded income tax expense of $473 million
on pre-tax earnings of $1.8 billion, or an effective tax rate of 26.5%, which
reflects the impact of the health insurer fee moratorium, partially offset by
the non-deductibility of a portion of our non-cash goodwill and intangible
impairment recorded in the third quarter of 2019.

Consolidated Total         $   3,082      $  1,781            73  %



Managed Care

Total revenues increased 50% in the year ended December 31, 2020, compared to
the corresponding period in 2019, primarily due to the acquisition of WellCare,
growth in the Medicaid and Health Insurance Marketplace businesses, and the
reinstatement of the health insurer fee in 2020. Additionally, the net effect of
the pandemic increased our revenues due to the suspension of Medicaid
eligibility redeterminations. The increase was partially offset by the
divestiture of our Illinois health plan. Earnings from operations increased $1.2
billion between years driven by the acquisition of WellCare, lower medical
utilization due to the COVID-19 pandemic, and the reinstatement of the health
insurer fee in 2020, partially offset by higher acquisition related expenses,
retroactive state premium rate adjustments and risk sharing mechanisms, and
higher testing and treatment costs associated with COVID-19, particularly in the
Health Insurance Marketplace business.

Specialty Services



Total revenues increased 17% in the year ended December 31, 2020, compared to
the corresponding period in 2019, resulting primarily from increased services
associated with membership growth in the Managed Care segment, acquisitions and
increased volume in our specialty pharmacy business. Earnings from operations
increased $76 million between years. Earnings from operations in 2020 was
negatively affected by the previously discussed impairment related to our
third-party care management software business and the results of the shared
savings programs in our physician home health business. Earnings from operations
in 2019 were negatively affected by the previously discussed non-cash goodwill
and intangible impairment related to our USMM physician home health business.

Cash Flows Provided by Operating Activities



Normal operations are funded primarily through operating cash flows and
borrowings under our Revolving Credit Facility. In 2020, operating activities
provided cash of $5.5 billion, or 3.1 times net earnings, compared to $1.5
billion in 2019. Cash flow provided by operations in 2020 was due to net
earnings, an increase in medical claims liabilities from growth and expansions,
and an increase in other long-term liabilities related to minimum MLR payables
and a delay in employer payroll tax payments related to the COVID-19 extensions
to payment deadlines.

Cash flows provided by operations in 2019 was primarily due to net earnings and
an increase in medical claims liabilities, primarily resulting from growth in
the Health Insurance Marketplace business and the commencement or expansion of
the Arkansas, Iowa, New Mexico, and Pennsylvania health plans. Operating cash
flows were partially offset by an increase in premium and trade receivables due
to the timing of payments from our state customers, as discussed below.

Cash flows from operations in each year can be impacted by the timing of
payments we receive from our states. As we have seen historically, 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.
                                                                        Year Ended December 31,

2020 and $1.5 billion in 2019. Cash flows used in investing activities in 2020
primarily consisted of our acquisitions of WellCare, PANTHERx and Apixio,
partially offset by divestiture proceeds. Cash flows used in investing
activities in 2020 also consisted of net additions to the investment portfolio
of our regulated subsidiaries (including transfers from cash and cash
equivalents to long-term investments) and capital expenditures.

We spent $869 million and $730 million in the years ended December 31, 2020 and 2019, respectively, on capital expenditures for system enhancements, market growth, and corporate headquarters expansions.



As of December 31, 2020, our investment portfolio consisted primarily of
fixed-income securities with a weighted average duration of 3.3 years. We had
unregulated cash and investments of $1.9 billion at December 31, 2020, compared
to $7.2 billion at December 31, 2019. Unregulated cash as of December 31, 2019
included the net proceeds from our $7.0 billion senior note issuance in advance
of the closing of the WellCare Acquisition. Unregulated cash and investments
include private equity investments and company owned life insurance contracts.

Cash flows used in investing activities in 2019 primarily consisted of the net
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 Provided by Financing Activities



Our financing activities provided cash of $260 million in 2020, compared to
providing cash of $6.8 billion in 2019. During 2020, our net financing
activities were due to increased borrowings, partially offset by common stock
repurchases. During 2019, our net financing activities primarily related to the
proceeds from the issuance of $7.0 billion of senior notes in December 2019 in
preparation of the WellCare Acquisition.

In connection with the WellCare Acquisition, in January 2020, we completed an
exchange offer for $1.2 billion of 5.25% Senior Notes due 2025 and $750 million
of 5.375% Senior Notes due 2026 (collectively, the WellCare Notes) issued by
WellCare and issued $1.1 billion aggregate principal amount of 5.25% Senior
Notes due 2025 and $747 million aggregate principal amount of 5.375% Senior
Notes due 2026. Additionally, our wholly owned subsidiary, WellCare Health
Plans, Inc., assumed the remaining unexchanged WellCare Notes.

In February 2020, we issued $2.0 billion 3.375% Senior Notes due 2030 (the $2.0
billion 2030 Notes). We used the net proceeds from the $2.0 billion 2030 Notes
to redeem all of our outstanding 2024 Notes. We recognized a pre-tax loss on
extinguishment of $44 million, including the call premium, the write-off of
unamortized debt issuance costs and a loss on the termination of the $1.0
billion interest rate swap associated with the 2024 Notes. We intended to use
remaining proceeds to redeem our 2022 Notes. The 2022 Notes were redeemed in the
fourth quarter in connection with an additional offering of senior notes as
further described below, and we decided to increase liquidity with the remaining
proceeds of the $2.0 billion 2030 Notes.

In February 2020, we terminated the interest rate swap agreements associated
with the 2022 Notes and the Senior Notes due January 15, 2025, (the 2025 Notes).
The interest rate swaps associated with the 2024 Notes were also terminated in
connection with the redemption of those notes as discussed above. In total, we
terminated three interest rate swap contracts with a notional amount of $2.1
billion.

In May 2020, we completed an exchange offer, whereby we offered to exchange all
of the outstanding $2.0 billion 3.375% Senior Notes due February 15, 2030, $1.0
billion 4.75% Senior Notes due 2025, $2.5 billion 4.25% Senior Notes, and $3.5
billion 4.625% Senior Notes due 2029 for identical securities that have been
registered under the Securities Act of 1933.

In October 2020, we issued $2.2 billion 3.0% Senior Notes due October 2030 (the
$2.2 billion 2030 Notes). We used the net proceeds from the offering, together
with cash on hand, to redeem all of the 2022 Notes and the $1.2 billion 5.25%
Senior Notes due 2025. We recognized a pre-tax loss on extinguishment of $17
million, including the call premium, and the write-off of unamortized debt
issuance costs.

Liquidity Metrics



The credit agreement underlying our Revolving Credit Facility and Term Loan
Facility contains customary covenants as well as financial covenants, including
a minimum fixed charge coverage ratio and a maximum debt-to-EBITDA ratio. Our
maximum debt-to-EBITDA ratio under the credit agreement may not exceed 3.5 to
1.0, which may, under certain circumstances and subject to certain elections
made by us, be increased for certain periods to 4.0 to 1.0. As of December 31,
2020, we had $97 million of borrowings outstanding under our Revolving Credit
Facility, $1.5 billion of borrowings outstanding under our Term Loan Facility,
and we were in compliance with all covenants. As of December 31, 2020, there
were no limitations on the availability of our Revolving Credit Facility as a
result of the debt-to-EBITDA ratio.

We have a $200 million non-recourse construction loan to fund the expansion of
our corporate headquarters. In February 2021, we extended the term of the
construction loan for one year. The loan bears interest based on the one month
LIBOR plus 2.70% and matures in April 2022. The agreement contains financial and
non-financial covenants aligning with the credit agreement governing our
Revolving Credit Facility. We have guaranteed completion of the construction
project associated with the loan. As of December 31, 2020, we had $180 million
in borrowings outstanding under the loan.

We had outstanding letters of credit of $129 million as of December 31, 2020,
which were not part of our Revolving Credit Facility. The letters of credit bore
weighted interest of 0.6% as of December 31, 2020. In addition, we had
outstanding surety bonds of $1.1 billion as of December 31, 2020.

The indentures governing our various maturities of senior notes contain limited
restrictive covenants. As of December 31, 2020, we were in compliance with all
covenants.

At December 31, 2020, we had working capital, defined as current assets less
current liabilities, of $1.8 billion, compared to $7.4 billion at December 31,
2019. Working capital as of December 31, 2019, reflected the net proceeds from
our $7.0 billion senior note issuance in advance of the closing of the WellCare
Acquisition. 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, 2020, our debt to capital ratio, defined as total debt divided
by the sum of total debt and total equity, was 39.3%, compared to 52.0% at
December 31, 2019. Excluding $230 million of non-recourse debt, our debt to
capital ratio was 39.0% as of December 31, 2020, compared to 51.7% at
December 31, 2019. At December 31, 2019, excluding non-recourse debt and the
senior notes issued to fund the WellCare Acquisition in advance of closing, our
debt to capital was 34.3%. We utilize the debt to capital ratio as a measure,
among others, of our leverage and financial flexibility.

We have a stock repurchase program authorizing us to repurchase common stock
from time to time on the open market or through privately negotiated
transactions. We have 5.5 million available shares remaining under the program
for repurchases as of December 31, 2020. No duration has been placed on the
repurchase program. We reserve the right to discontinue the repurchase program
at any time. In 2020, we used proceeds from divestitures to repurchase
8.7 million shares of Centene common stock for $500 million through our stock
repurchase program. We did not make any repurchases under this plan during 2019.

During the year ended December 31, 2020 and 2019, we received dividends of $1.3 billion and $713 million, respectively, from our regulated subsidiaries.

2021 Expectations



During 2021, we expect to receive net dividends of approximately $1.7 billion
from our regulated subsidiaries and expect to spend approximately $860 million
in capital expenditures primarily associated with system enhancements and market
and corporate headquarters expansions. In February 2021, our Board of Directors
approved an increase in our existing share repurchase program for our common
stock. With the increase, we are authorized to repurchase up to $1.0 billion of
shares of our common stock, inclusive of the previously approved stock
repurchase program. No duration has been placed on the repurchase program.

In February 2021, we issued $2.2 billion 2.50% Senior Notes due 2031 (the 2031
Notes). In conjunction with the 2031 Notes offering, we completed a tender offer
(the Tender Offer) to purchase for cash, subject to certain conditions, any and
all of the outstanding aggregate principal amount of the $2.2 billion 4.75%
Senior Notes due 2025 (the 2025 Notes). We used the net proceeds from the 2031
Notes, together with available cash on hand, to fund the purchase price for the
2025 Notes accepted for purchase in the Tender Offer (approximately 36% of the
aggregate principal amount outstanding) and intend to use the remaining proceeds
to redeem any of the 2025 Notes that remain outstanding following the Tender
Offer, including all premiums, accrued interest and costs and expenses related
to the redemption.

We have material debt, lease, and short-term medical claims obligations. Refer
to Note 10. Debt, Note 11. Leases, and Note 8. Medical Claims Liability,
respectively, for further information. In addition, we have material commitments
as a result of our Fidelis and Health Net acquisitions. Refer to Note 17.
Commitments for detail.

In the second half of 2021, we expect to complete the merger with Magellan Health, Inc. for $95.00 per share in cash for a total enterprise value of approximately $2.2 billion. We intend to primarily fund the acquisition through debt financing.



Based on our operating plan, we expect that our available cash, cash equivalents
and investments, cash from our operations and cash available under our Revolving
Credit Facility will be sufficient to finance our general operations and capital
expenditures for at least 12 months from the date of this filing. While we are
currently in a strong liquidity position and believe we have adequate access to
capital, we may elect to increase borrowings on our Revolving Credit Facility.
In addition, 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 or redemption opportunities to extend
maturities and/or improve terms of our indebtedness if we believe such
opportunities are favorable to us.

                  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.

As of December 31, 2020, our subsidiaries had aggregate statutory capital and
surplus of $14.2 billion, compared with the required minimum aggregate statutory
capital and surplus requirements of $5.9 billion. During the year ended
December 31, 2020, we received $508 million of net dividends from our regulated
subsidiaries. For our subsidiaries that file with the National Association of
Insurance Commissioners (NAIC), we estimate our Risk Based Capital (RBC)
percentage to be in excess of 350% of the Authorized Control Level.

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 healthcare expenditures, excluding capitated
amounts. In addition, certain of our California subsidiaries have made certain
undertakings to the Department of Managed Health Care 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.

Under the New York State Department of Health Codes, Rules and Regulations Title
10, Part 98, our New York subsidiary must comply with contingent reserve
requirements. Under these requirements, net worth based upon admitted assets
must equal or exceed a minimum amount based on annual net premium income.

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, 2020, 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, 2020, the amount of capital
and surplus or net worth that was unavailable for the payment of dividends or
return of capital to us was $5.9 billion 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.


                   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 intangible assets, medical claims liability and revenue
recognition 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 purchased
contract rights and customer relationships, provider contracts, trade names,
developed technologies, and goodwill. Key assumptions used in the valuation of
these intangible assets include, but are not limited to, member attrition rates,
contract renewal probabilities, revenue growth rates, expectations of
profitability, and discount and royalty rates. We
                                       56

--------------------------------------------------------------------------------

Table of Contents



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, 2020, we had $18.7 billion of goodwill and
$8.4 billion of other intangible assets.

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


                      Intangible Asset                          

Amortization Period


  Purchased contract rights and customer relationships             3 - 21 years
  Provider contracts                                               4 - 15 years
  Trade names                                                      7 - 20 years
  Developed technologies                                            2 - 7 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,
financial performance, state funding, medical contracts and provider networks
and contracts.

If a reporting unit's carrying amount exceeds its fair value, an entity will
record an impairment charge based on that difference. The impairment charge will
be limited to the amount of goodwill allocated to that reporting unit. We first
assess qualitative factors to determine if a quantitative impairment test is
necessary. 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.

Our specialty clinical healthcare business acquired in 2018, with goodwill of
$325 million, has experienced short-term decreased profitability due to
short-term rate inadequacies and the effect of the COVID-19 pandemic, coupled
with immigration restrictions enacted by policy administrators. However, the
goodwill is expected to be recovered and there have been no fundamental changes
in the business model since the acquisition date. To the extent rates do not
improve in the long-term or the new administration does not reverse the
immigration restrictions, the reporting unit could be at risk for impairment.

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. The claims amounts ultimately settled will most
likely 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
                                       57

--------------------------------------------------------------------------------

Table of Contents

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 that have been received or adjudicated as of the end of a reporting
period relative to the estimate of the total ultimate incurred costs for that
same period. 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 results of operations, financial position and 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.

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, 2020 data:
                 Completion Factors: (1)                                        Cost Trend Factors: (2)

(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 $80 million for the year
ended December 31, 2020, 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.

(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, 2020
will be known by the end of 2021.

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 $86
million, $49 million and $25 million of the "Incurred related to: Prior years"
was recorded as a reduction to premium revenues in 2020, 2019 and 2018,
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
population health management initiatives may also contribute to changes in
medical claim liability estimates. While we have evidence that population health
management initiatives are effective on a case by case basis, these 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 population health management initiative are not
known by us. Additionally, certain population health 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 population health 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 population health 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 department program designed to collaboratively work with hospitals to
steer non-emergency care away from the costly emergency department setting
(through patient education, on-site alternative urgent care settings, etc.).

•Increased 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, premiums received from our members and
CMS for our Medicare product, and premiums from members of our commercial health
plans. In addition to member premium payments, our Marketplace contracts also
generate revenues from subsidies received from CMS. We generally receive a fixed
premium per member per month pursuant to our 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 or CMS
analyzing submissions of processed claims data to determine the acuity of our
membership relative to the entire state's 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, including commercial plans, our plans may be required to return
premium to the state or policyholders 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 or CMS, which is adjusted on a monthly basis by the states or CMS 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 update 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.

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 healthcare 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.

For qualifying low income PDP members, CMS pays for some, or all, of the
member's monthly premium. We receive certain Part D prospective subsidy payments
from CMS for our PDP members as a fixed monthly per member amount, based on the
estimated costs of providing prescription drug benefits over the plan year, as
reflected in our bids. Approximately nine to ten months subsequent to the end of
the plan year, or later in the case of the coverage gap discount subsidy, a
settlement payment is made between CMS and our plans based on the difference
between the prospective payments and actual claims experience.

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. For
performance-based measures in our contracts, revenue is recognized as data
sufficient to measure performance is available. We recognize revenue related to
administrative services under the TRICARE government-sponsored managed care
support contract for the DoD's TRICARE program on a straight-line basis over the
option period, when the fees become fixed and determinable. The TRICARE contract
includes various performance-based measures. For each of the measures, an
estimate of the amount that has been earned is made at each interim date, and
revenue is recognized accordingly.

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. The ACA imposed
the HIF in 2014, 2015, 2016, 2018 and 2020. The HIF was suspended in 2017 and
2019. Beginning in 2021, the HIF was permanently repealed. 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. For certain products, premium taxes, state assessments and the HIF
are not pass-through payments and are recorded as premium revenue and premium
tax expense or health insurer fee expense in the Consolidated Statements of
Operations.

Some states require state directed payments that have minimal risk, but are
administered as a premium adjustment. These payments are recorded as premium
revenue and medical costs at close to a 100% HBR. We have little visibility to
the timing of these payments until they are paid by the state.
