EXECUTIVE OVERVIEW
General
UnitedHealth Group is a diversified health care company with a mission to help
people live healthier lives and help make the health system work better for
everyone. Our two complementary businesses - Optum and UnitedHealthcare - are
driven by this unified mission and vision to improve health care access,
affordability, experiences and outcomes for the individuals and organizations we
are privileged to serve.
We have four reportable segments across our two business platforms, Optum and
UnitedHealthcare:
•Optum Health;
•Optum Insight;
•Optum Rx; and
•UnitedHealthcare, which includes UnitedHealthcare Employer & Individual,
UnitedHealthcare Medicare & Retirement, UnitedHealthcare Community & State and
UnitedHealthcare Global.
Further information on our business and reportable segments is presented in
  Part I, Item 1, "Business"   and in   Note 13 of the Notes to the Consolidated
Financial Statements included in Part II, Item 8, "Financial Statements     and
Supplementary Data    .    "
Business Trends
Our businesses participate in the United States, South America and certain other
international health markets. In the United States, health care spending has
grown consistently for many years and comprises 18% of gross domestic product
(GDP). We expect overall spending on health care to continue to grow in the
future, due to inflation, medical technology and pharmaceutical advancement,
regulatory requirements, demographic trends in the population and national
interest in health and well-being. The rate of market growth may be affected by
a variety of factors, including macroeconomic conditions, such as the economic
impact of COVID-19, and regulatory changes, which could impact our results of
operations, including our continued efforts to control health care costs.
Pricing Trends. To price our health care benefit products, we start with our
view of expected future costs, including any potential impacts from COVID-19. We
frequently evaluate and adjust our approach in each of the local markets we
serve, considering relevant factors, such as product positioning, price
competitiveness and environmental, competitive, legislative and regulatory
considerations, including minimum MLR thresholds. We will continue seeking to
balance growth and profitability across all of these dimensions.
The commercial risk market remains highly competitive in the small group, large
group and individual segments. We expect broad-based competition to continue as
the industry adapts to individual and employer needs.
Medicare Advantage funding continues to be pressured, as discussed below in
  "Regulatory Trends and Uncertainties."
We expect Medicaid revenue growth due to anticipated changes in mix and pricing
trends; we also believe the payment rate environment creates the risk of
continued downward pressure on Medicaid margin percentages. We continue to take
a prudent, market-sustainable posture for both new business and maintenance of
existing relationships. We continue to advocate for actuarially sound rates
commensurate with our medical cost trends and we remain dedicated to partnering
with those states that are committed to the long-term viability of their
programs.

Medical Cost Trends. Our medical cost trends primarily relate to changes in unit
costs, health system utilization and prescription drug costs. COVID-19 related
care costs as well as the deferral of care have impacted medical cost trends in
2021 and may continue to do so in 2022 and subsequent years. Future medical cost
trends may be impacted by increased consumer demand for care, potentially even
higher acuity care, due to the temporary deferral of care since the onset of the
pandemic. We endeavor to mitigate those increases by engaging physicians and
consumers with information and helping them make clinically sound choices, with
the objective of helping them achieve high-quality, affordable care. The
continued uncertain impact of COVID-19 may impact our ability to estimate
medical costs payable, which has resulted in, and could continue to result in,
increased variability to medical cost reserve development.
Delivery System and Payment Modernization. The health care market continues to
change based on demographic shifts, new regulations, political forces and both
payer and patient expectations. Health plans and care providers are being called
upon to work together to close gaps in care and improve overall care quality,
improve the health of populations and reduce costs. We continue to see a greater
number of people enrolled in plans with underlying performance-based care
provider payment models rewarding high-quality, affordable care and foster
collaboration. We work together with clinicians to leverage our data and
analytics to provide the necessary information to close gaps in care and improve
overall health outcomes for patients.
This trend is creating needs for health management services which can coordinate
care around the primary care physician, including new primary care channels, and
for investments in new clinical and administrative information and management
systems, which we believe provide growth opportunities for our Optum business
platform.
Regulatory Trends and Uncertainties
Following is a summary of management's view of the trends and uncertainties
related to regulatory matters. For additional information regarding regulatory
trends and uncertainties, see   Part I, Item 1 "Business - Government
Regulation"   and   Item 1A, "Risk Factors."
Medicare Advantage Rates. Final 2022 Medicare Advantage rates resulted in an
increase in industry base rates of approximately 4.1%, short of the industry
forward medical cost trend, creating continued pressure in the Medicare
Advantage program.
The ongoing Medicare Advantage funding pressure places continued importance on
effective medical management and ongoing improvements in administrative
efficiency. There are a number of adjustments we have made to partially offset
these rate pressures and reductions. In some years, these adjustments impact the
majority of the seniors we serve through Medicare Advantage. For example, we
seek to intensify our medical and operating cost management, make changes to the
size and composition of our care provider networks, adjust members' benefits and
implement or increase the member premiums supplementing the monthly payments we
receive from the government. Additionally, we decide annually on a
county-by-county basis where we will offer Medicare Advantage plans.
Our Medicare Advantage rates are currently enhanced by CMS quality bonuses in
certain counties based on our local plans' Star ratings. The level of Star
ratings from CMS, based upon specified clinical and operational performance
standards, will impact future quality bonuses.
ACA Tax (Health Insurance Tax). The Health Insurance Tax was permanently
repealed by Congress, effective January 1, 2021. The permanent repeal of the tax
impacts year-over-year comparability of our financial statements, including
revenues, operating costs, medical care ratio (MCR), operating cost ratio,
effective tax rate and cash flows from operations.
COVID-19 Trends and Uncertainties
The COVID-19 pandemic continues to evolve and the ultimate impact on our
business, results of operations, financial condition and cash flows remains
uncertain. In 2021, overall care activity continued to increase, including a mix
of temporary deferral of care activity and COVID-19 related care costs. The
temporary deferral of care was more than offset by COVID-19 related care and
testing costs, rebate requirements and other revenue impacts and general
economic impacts. In future periods, care patterns may moderately exceed normal
baselines as previously deferred care is obtained and acuity temporarily rises
due to missed regular care. From time to time, health system capacity may be
subject to possible increased volatility due to the pandemic. Specific trends
and uncertainties related to our two business platforms are as follows:
Optum. COVID-19 related care costs continued to impact our Optum Health
value-based care delivery businesses, which were partially offset by the
continued temporary deferral of care. The temporary deferral of care reduced
fee-for-service care delivery volume, as well as Optum Insight and Optum Rx
volume-based business activity, although we expect the impact to continue
decreasing as care returns to, and potentially exceeds, normal levels. We
believe COVID-19 will continue to influence customer and consumer behavior, both
during and after the pandemic, which could impact how and where care is
delivered and the manner in which consumers wish to receive their prescription
drugs or infusion services. As a result of the dynamic situation and
broad-reaching impact to the health system, the ultimate impact of COVID-19 on
our Optum businesses is uncertain.

  Table of Contents
UnitedHealthcare. In 2021, we continued expanded benefit coverage in areas such
as COVID-19 related care and testing, telemedicine, and pharmacy; we also
continued to assist our customers, care providers, members and communities in
addressing the COVID-19 crisis. UnitedHealthcare's 2021 results of operations
were negatively impacted by COVID-19 related care and testing, rebate
requirements and other revenue impacts, as well as broader economic impacts,
partially offset by the continued deferral of care. The increase in people
served through Medicaid was attributable in part to continuing action by states
to ease eligibility redetermination requirements due to the COVID-19 public
health emergency.
Disrupted care patterns, as a result of the pandemic, have affected and may
continue to temporarily affect the ability to obtain complete member health
status information, impacting revenue in businesses utilizing risk adjustment
methodologies. The ultimate overall impact is uncertain and dependent on the
future pacing, intensity and duration of the pandemic, the severity of new
variants of the COVID-19 virus, the effectiveness and extent of administration
of vaccination and treatments and general economic uncertainty.

2021 RESULTS OF OPERATIONS COMPARED TO 2020 RESULTS
Consolidated Financial Results
Revenues
The increases in revenues were primarily driven by the increase in the number of
individuals served through Medicare Advantage, Medicaid and commercial
offerings; pricing trends; and organic and acquisition growth across the Optum
business, primarily due to expansion in care delivery.
Medical Costs and MCR
Medical costs increased as a result of growth in people served through Medicare
Advantage, Medicaid and commercial offerings, as well as increased COVID-19
related care costs and medical cost trends, partially offset by higher temporary
care deferrals. The MCR increased due to increased COVID-19 related care costs
and the permanent repeal of the Health Insurance Tax, partially offset by
increased temporary care deferrals. Medical costs and the MCR were also impacted
by increased prior year favorable reserve development.

Operating Cost Ratio
The operating cost ratio decreased primarily due to the permanent repeal of the
Health Insurance Tax, COVID-19 impacts on revenue and operating costs in the
prior year and operating efficiency gains, partially offset by business mix.
Income Tax Rate
Our effective tax rate decreased primarily due to the permanent repeal of the
nondeductible Health Insurance Tax.
Reportable Segments
See   Note 13 of Notes to the Consolidated Financial Statements included in Part
II, Item 8, "Financial Statements     and Supplement    ary Data     "   for
more information on our segments. We utilize various metrics to evaluate and
manage our reportable segments, including individuals served by UnitedHealthcare
by major market segment and funding arrangement, people served by Optum Health
and adjusted scripts for Optum Rx. These metrics are the main drivers of
revenue, earnings and cash flows at each business. The metrics also allow
management and investors to evaluate and understand business mix, including the
mix of care delivered through accountable care models at Optum Health, customer
penetration and pricing trends when comparing the metrics to revenue by segment.

Commercial business increased primarily due to acquisitions in risk-based and
fee-based offerings and organic growth in innovative products. Medicare
Advantage increased due to growth in people served through individual and group
Medicare Advantage plans. The increase in people served through Medicaid was
primarily driven by states continuing to ease redetermination requirements due
to COVID-19, new state-based awards and growth in people served through Dual
Special Needs Plans.
UnitedHealthcare's revenues increased due to growth in the number of individuals
served through Medicare Advantage and Medicaid, including a greater mix of
people with higher acuity needs, and an increase in the number of individuals
served through commercial benefits, partially offset by the permanent repeal of
the Health Insurance Tax and the impacts of COVID-19 on risk adjusted business.
Earnings from operations decreased due to increased COVID-19 related care costs
and the impacts of COVID-19 on risk adjusted business, partially offset by
higher temporary deferral of care and growth in people served across our
domestic businesses.
Optum
Total revenues and earnings from operations increased due to growth across the
Optum businesses. The results by segment were as follows:
Optum Health
Revenues at Optum Health increased primarily due to organic growth in
value-based arrangements, acquisitions in care delivery and the impact of
COVID-19 at our fee-based businesses as consumers resumed elective care.
Earnings from operations increased due to the factors impacting revenues as well
as cost management initiatives and increased investment income. COVID-19 related
care costs and temporary care deferrals affected earnings from operations at our
value-based and fee-based businesses in offsetting manners. Optum Health served
approximately 100 million people as of December 31, 2021 compared to 98 million
people as of December 31, 2020.
Optum Insight
Revenues and earnings from operations at Optum Insight increased due to growth
in technology and managed services, including expanding relationships serving
health systems. Earnings from operations also increased due to productivity
gains and cost management initiatives.
Optum Rx
Revenues and earnings from operations at Optum Rx increased due to higher script
volumes from growth in people served, increased utilization and organic growth
in pharmacy care services. Earnings from operations also increased as a result
of continued supply chain and cost management initiatives. Optum Rx fulfilled
1.4 billion and 1.3 billion adjusted scripts in 2021 and 2020, respectively. In
addition to the factors contributing to revenue growth, adjusted scripts also
increased due to the dispensing of COVID-19 vaccines.

LIQUIDITY, FINANCIAL CONDITION AND CAPITAL RESOURCES
Liquidity
Introduction
We manage our liquidity and financial position in the context of our overall
business strategy. We continually forecast and manage our cash, investments,
working capital balances and capital structure to meet the short-term and
long-term obligations of our businesses while seeking to maintain liquidity and
financial flexibility. Cash flows generated from operating activities are
principally from earnings before noncash expenses.
Our regulated subsidiaries generate significant cash flows from operations and
are subject to, among other things, minimum levels of statutory capital, as
defined by their respective jurisdictions, and restrictions on the timing and
amount of dividends paid to their parent companies.
Our U.S. regulated subsidiaries paid their parent companies dividends of $8.0
billion and $8.3 billion in 2021 and 2020, respectively.   See     Note 10 of
the Notes to the Consolidated Financial Statements included in Part II, Item 8,
"Financial Statements     and Supplementary Data    "   for further detail
concerning our regulated subsidiary dividends.
Our nonregulated businesses also generate significant cash flows from operations
available for general corporate use. Cash flows generated by these entities,
combined with dividends from our regulated entities and financing through the
issuance of long-term debt as well as issuance of commercial paper or the
ability to draw under our committed credit facilities, further strengthen our
operating and financial flexibility. We use these cash flows to expand our
businesses through acquisitions, reinvest in our businesses through capital
expenditures, repay debt and return capital to our shareholders through
dividends and repurchases of our common stock.

2021 Cash Flows Compared to 2020 Cash Flows
Cash flows provided by operating activities were largely consistent, with higher
net earnings being offset by changes in working capital accounts. Other
significant changes in sources or uses of cash year-over-year included decreased
customer funds administered and increased purchases of redeemable noncontrolling
interests, share repurchases and cash dividends paid, partially offset by
decreased cash paid for acquisitions and net purchases of investments.
                                       31

  Table of Contents
Financial Condition
As of December 31, 2021, our cash, cash equivalent, available-for-sale debt
securities and equity securities balances of $65.1 billion included $21.4
billion of cash and cash equivalents (of which $2.8 billion was available for
general corporate use), $40.2 billion of debt securities and $3.5 billion of
equity securities. Given the significant portion of our portfolio held in cash
equivalents, we do not anticipate fluctuations in the aggregate fair value of
our financial assets to have a material impact on our liquidity or capital
position. Other sources of liquidity, primarily from operating cash flows and
our commercial paper program, which is fully supported by our bank credit
facilities, reduce the need to sell investments during adverse market
conditions. See   Note 4 of the Notes to the Consolidated Financial Statements
included in Part II, Item 8, "Financial Statements     and Supplementary
Data    "   for further detail concerning our fair value measurements.
Our available-for-sale debt portfolio had a weighted-average duration of 3.9
years and a weighted-average credit rating of "Double A" as of December 31,
2021. When multiple credit ratings are available for an individual security, the
average of the available ratings is used to determine the weighted-average
credit rating.
Capital Resources and Uses of Liquidity
Cash Requirements. The Company's cash requirements within the next twelve months
include medical costs payable, accounts payable and accrued liabilities,
short-term borrowings and current maturities of long-term debt, other current
liabilities, and purchase commitments and other obligations. We expect the cash
required to meet these obligations to be primarily generated through cash flows
from current operations; cash available for general corporate use; and the
realization of current assets, such as accounts receivable.
Our long-term cash requirements under our various contractual obligations and
commitments include:
•Debt Obligations. See   Note 8 of the Notes to the Consolidated Financial
Statements included in Part II, Item 8, "Financial Statements     and
Supplementary Data    "   for further detail of our long-term debt and the
timing of expected future payments. Interest coupon payments are typically paid
semi-annually.
•Operating leases. See   Note 12 of the Notes to the Consolidated Financial
Statements included in Part II, Item 8, "Financial Statements     and
Supplementary Data    "   for further detail of our obligations and the timing
of expected future payments.
•Purchase and other obligations. These include $4.7 billion, $2.7 billion of
which is expected to be paid within the next twelve months, of fixed or minimum
commitments under existing purchase obligations for goods and services,
including agreements cancelable with the payment of an early termination
penalty, and remaining capital commitments for venture capital funds and other
funding commitments. These amounts exclude agreements cancelable without penalty
and liabilities to the extent recorded in our Consolidated Balance Sheets as of
December 31, 2021.
•Other Liabilities. These include other long-term liabilities reflected in our
Consolidated Balance Sheets as of December 31, 2021, including obligations
associated with certain employee benefit programs, unrecognized tax benefits and
various long-term liabilities, which have some inherent uncertainty in the
timing of these payments.
•Redeemable noncontrolling interests. See   Note 2 of the Notes to the
Consolidated Financial Statements included in Part II, Item 8, "Financial
Statements     and Supplementary Data    "   for further detail. We do not have
any material required redemptions in the next twelve months.
We expect the cash required to meet our long-term obligations to be primarily
generated through future cash flows from operations. However, we also have the
ability to generate cash to satisfy both our current and long-term requirements
through the issuance of commercial paper, issuance of long-term debt, or drawing
under our committed credit facilities or the ability to sell investments. We
believe our capital resources are sufficient to meet future, short-term and
long-term, liquidity needs.
Short-Term Borrowings. Our revolving bank credit facilities provide liquidity
support for our commercial paper borrowing program, which facilitates the
private placement of senior unsecured debt through independent broker-dealers,
and are available for general corporate purposes. For more information on our

Consolidated Financial Statements included in Part II, Item 8, "Financial

Our revolving bank credit facilities contain various covenants, including
covenants requiring us to maintain a defined debt to debt-plus-shareholders'
equity ratio of not more than 60%, subject to increase in certain circumstances
set forth in the applicable credit agreement. As of December 31, 2021, our debt
to debt-plus-shareholders' equity ratio, as defined and calculated under the
credit facilities, was 36%.
Long-Term Debt. Periodically, we access capital markets to issue long-term debt
for general corporate purposes, such as, to meet our working capital
requirements, to refinance debt, to finance acquisitions or for share
repurchases. For more information on our debt, see   Note 8 of the Notes to the
Consolidated Financial Statements included in Part II, Item 8 "Financial

The availability of financing in the form of debt or equity is influenced by
many factors, including our profitability, operating cash flows, debt levels,
credit ratings, debt covenants and other contractual restrictions, regulatory
requirements and economic and market conditions. A significant downgrade in our
credit ratings or adverse conditions in the capital markets may increase the
cost of borrowing for us or limit our access to capital.
Share Repurchase Program. As of December 31, 2021, we had Board authorization to
purchase up to 45 million shares of our common stock. For more information on
our share repurchase program, see   Note 10 of the Notes to the Consolidated
Financial Statements included in Part II, Item 8, "Financial Statements.    and
Supplementary Data    .    "
Dividends. In June 2021, the Company's Board of Directors increased the
Company's quarterly cash dividend to shareholders to an annual rate of $5.80
compared to $5.00 per share, which the Company had paid since June 2020. For
more information on our dividend, see   Note 10 of the Notes to the Consolidated
Financial Statements included in Part II, Item 8, "Financial Statements.    and
Supplementary Data    .    "
Pending Acquisitions. In 2021, we entered into agreements to acquire multiple
companies in the health care sector, most notably, Change Healthcare (NASDAQ:
CHNG), subject to regulatory approval and other customary closing conditions.
Additionally, in January 2022, we entered into agreements to acquire multiple
companies in the health care sector, subject to regulatory approval and other
customary closing conditions. The total anticipated capital required for these
acquisitions, excluding the payoff of acquired indebtedness, is approximately
$12 billion.
We do not have other significant contractual obligations or commitments
requiring cash resources. However, we continually evaluate opportunities to
expand our operations, which include internal development of new products,
programs and technology applications and may include acquisitions.
CRITICAL ACCOUNTING ESTIMATES
Critical accounting estimates are those estimates requiring management to make
challenging, subjective or complex judgments, often because they must estimate
the effects of matters inherently uncertain and may change in subsequent
periods. Critical accounting estimates involve judgments and uncertainties which
are sufficiently sensitive and may result in materially different results under
different assumptions and conditions.
Medical Costs Payable
Medical costs and medical costs payable include estimates of our obligations for
medical care services rendered on behalf of consumers, but for which claims have
either not yet been received or processed. Depending on the health care
professional and type of service, the typical billing lag for services can be up
to 90 days from the date of service. Approximately 90% of claims related to
medical care services are known and settled within 90 days from the date of
service and substantially all within twelve months. As of December 31, 2021, our
days outstanding in medical payables was 47 days, calculated as total medical
payables divided by total medical costs times the number of days in the period.
In each reporting period, our operating results include the effects of more
completely developed medical costs payable estimates associated with previously
reported periods. If the revised estimate of prior period medical costs is less
than the previous estimate, we will decrease reported medical costs in the
current period (favorable development). If the revised estimate of prior period
medical costs is more than the previous estimate, we will increase reported
medical costs in the current period (unfavorable development). Medical costs in
2021, 2020 and 2019 included favorable medical cost development related to prior
years of $1.7 billion, $880 million and $580 million, respectively.
In developing our medical costs payable estimates, we apply different estimation
methods depending on the month for which incurred claims are being estimated.
For example, for the most recent two months, we estimate claim costs incurred by
applying observed medical cost trend factors to the average per member per month
(PMPM) medical costs incurred in prior months for which more complete claim data
is available, supplemented by a review of near-term completion factors.
Completion Factors. A completion factor is an actuarial estimate, based upon
historical experience and analysis of current trends, of the percentage of
incurred claims during a given period adjudicated by us at the date of
estimation. Completion factors are the most significant factors we use in
developing our medical costs payable estimates for periods prior to the most
recent two months. Completion factors include judgments in relation to claim
submissions such as the time from date of service
                                       33

to claim receipt, claim levels and processing cycles, as well as other factors.
Our judgments also consider the impacts of COVID-19 on these factors. If actual
claims submission rates from providers (which can be influenced by a number of
factors, including provider mix and electronic versus manual submissions) or our
claim processing patterns are different than estimated, our reserve estimates
may be significantly impacted.
The following table illustrates the sensitivity of these factors and the
estimated potential impact on our medical costs payable estimates for those
periods as of December 31, 2021:
Completion Factors                      Increase (Decrease)

Medical Cost Per Member Per Month Trend Factors. Medical cost PMPM trend factors
are significant factors we use in developing our medical costs payable estimates
for the most recent two months. Medical cost trend factors are developed through
a comprehensive analysis of claims incurred in prior months, provider
contracting and expected unit costs, benefit design and a review of a broad set
of health care utilization indicators, which included consideration of COVID-19.
These factors include but are not limited to pharmacy utilization trends,
inpatient hospital authorization data and influenza incidence data from the
National Centers for Disease Control. We also consider macroeconomic variables
such as GDP growth, employment and disposable income. A large number of factors
can cause the medical cost trend to vary from our estimates, including: our
ability and practices to manage medical and pharmaceutical costs, changes in
level and mix of services utilized; mix of benefits offered, including the
impact of co-pays and deductibles; changes in medical practices; and
catastrophes, epidemics and pandemics, such as COVID-19.
The following table illustrates the sensitivity of these factors and the
estimated potential impact on our medical costs payable estimates for the most
recent two months as of December 31, 2021:
Medical Cost PMPM Quarterly Trend          Increase (Decrease)
Increase (Decrease) in Factors          In Medical Costs Payable

1                                                            298
(1)                                                         (298)
(2)                                                         (597)
(3)                                                         (895)


The completion factors and medical costs PMPM trend factors analyses above
include outcomes considered reasonably likely based on our historical experience
estimating liabilities for incurred but not reported benefit claims.
Management believes the amount of medical costs payable is reasonable and
adequate to cover our liability for unpaid claims as of December 31, 2021;
however, actual claim payments may differ from established estimates as
discussed above. Assuming a hypothetical 1% difference between our December 31,
2021 estimates of medical costs payable and actual medical costs payable,
excluding AARP Medicare Supplement Insurance and any potential offsetting impact
from premium rebates, 2021 net earnings would have increased or decreased by
approximately $184 million.
For more detail related to our medical cost estimates, see   Note 2 of the Notes
to the Consolidated Financial Statements included in Part II, Item 8, "Financial
Statements     and Supplementary Data    ."
Goodwill
We evaluate goodwill for impairment annually or more frequently when an event
occurs or circumstances change indicating the carrying value may not be
recoverable. When testing goodwill for impairment, we may first assess
qualitative factors to determine if it is more likely than not the carrying
value of a reporting unit exceeds its estimated fair value. During a qualitative
analysis, we consider the impact of changes, if any, to the following factors:
macroeconomic, industry and market factors; cost
                                       34

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


  Table of Contents
factors; changes in overall financial performance; and any other relevant events
and uncertainties impacting a reporting unit. If our qualitative assessment
indicates a goodwill impairment is more likely than not, we perform additional
quantitative analyses. We may also elect to skip the qualitative testing and
proceed directly to the quantitative testing. For reporting units where a
quantitative analysis is performed, we perform a test measuring the fair values
of the reporting units and comparing them to their aggregate carrying values,
including goodwill. If the fair value is less than the carrying value of the
reporting unit, an impairment is recognized for the difference, up to the
carrying amount of goodwill.
We estimate the fair values of our reporting units using a discounted cash flow
method or a weighted combination of discounted cash flows and a market-based
method. The discounted cash flow method includes assumptions about a wide
variety of internal and external factors. Significant assumptions used in the
discounted cash flow method include financial projections of free cash flow,
including revenue trends, medical costs trends, operating productivity, income
taxes and capital levels; long-term growth rates for determining terminal value
beyond the discretely forecasted periods; and discount rates. Financial
projections and long-term growth rates used for our reporting units are
consistent with, and use inputs from, our internal long-term business plan and
strategies. Discount rates are determined for each reporting unit and include
consideration of the implied risk inherent in their forecasts. Our most
significant estimate in the discount rate determinations involves our
adjustments to the peer company weighted average costs of capital reflecting
reporting unit-specific factors. We have not made any adjustments to decrease a
discount rate below the calculated peer company weighted average cost of capital
for any reporting unit. Company-specific adjustments to discount rates are
subjective and thus are difficult to measure with certainty. The passage of time
and the availability of additional information regarding areas of uncertainty
with respect to the reporting units' operations could cause these assumptions to
change in the future. Additionally, as part of our quantitative impairment
testing, we perform various sensitivity analyses on certain key assumptions,
such as discount rates, cash flow projections and peer company multiples to
analyze the potential for a material impact. The market-based method requires
determination of an appropriate peer group whose securities are traded on an
active market. The peer group is used to derive market multiples to estimate
fair value. As of October 1, 2021, we completed our annual impairment tests for
goodwill with all of our reporting units having fair values substantially in
excess of their carrying values.
LEGAL MATTERS
A description of our legal proceedings is presented in   Note 12 of Notes to the
Consolidated Financial Statements included in Part II, Item 8, "Financial
Statements     and Supplementary Data    ."
CONCENTRATIONS OF CREDIT RISK
Investments in financial instruments such as marketable securities and accounts
receivable may subject us to concentrations of credit risk. Our investments in
marketable securities are managed under an investment policy authorized by our
Board of Directors. This policy limits the amounts which may be invested in any
one issuer and generally limits our investments to U.S. government and agency
securities, state and municipal securities and corporate debt obligations of
investment grade. Concentrations of credit risk with respect to accounts
receivable are limited due to the large number of employer groups and other
customers constituting our client base. As of December 31, 2021, there were no
significant concentrations of credit risk.
