work to achieve that goal in a manner that is 

accountable to society and our shareholders. We 

draw upon the creative and competitive strength 

of the open market to support our efforts. We 

use private sector capital to grow and advance 

in sustainable and profitable ways, based 

on the quality and consistency of the work we 

do, the trust we earn and the ever-improving 

value we deliver to those we serve, providing a 

distinctive return on capital to those who invest.

Working together to 
make Health care better

At UnitedHealth Group, we think of health care as a system — a highly complex 
system of interacting, interrelated, interdependent elements that is continually 
changing. We see our enterprise as one of many participants in this expansive system, 
along with millions of health care consumers, physicians, nurses and other providers 
of care, hospitals and clinics, federal and state governments, employers of all sizes, 
pharmaceutical and medical device manufacturers and insurers. 

the health care system resides within a broad, vital 

and quality of life. It is where we must respond to the 

social and economic environment, which is also 

interests of the most vulnerable in our communities.

complex and ever changing. economically, it is a free 

market system, based on basic principles of supply 

and demand, and is among the most regulated. 

the health care system is also important politically 

because of social expectations related to health care 

access, quality and costs.

We have endeavored to build UnitedHealth Group 

into that changing system, as an enterprise that 

is highly adaptable to the evolving health care 

environment and committed to taking responsible 

positions for enabling and driving positive change 

across health care.

at its core, this system deals with the 
most central of human needs — the 
healing, preservation and quality of life.

the challenge we all face is that this system does 

not function systematically. It is highly fragmented, 

yet its separate elements are profoundly interlinked 

within local communities. Health care is among the 

most local of activities, and these local communities 

have real and significant differences in basic supply

the medicaid market is 
expected to grow more 
than 28 percent by 2021.

Integral to our innovative 

approach to medicare, we have 

built a leading direct-to-consumer 

marketing platform and a 

broad product portfolio that we 

offer to seniors across a wide 

geographic footprint. With only 

25 percent of medicare recipients 

in managed care, the opportunity 

to serve more seniors in this 

growing market is substantial.

Very consciously and methodically, we are building  

a company culture that reinforces the socially  

sensitive nature of our work — a culture of integrity, 

compassion and trusting relationships, as well as 

innovation and high performance.

our Health benefits platform, UnitedHealthcare, is a 

In medicaid, our attraction for state governments is 

built on managing the needs of medically complex,

existing markets and expand thoughtfully into new

over the next decade, the individual health benefits 

market is expected to double in size from 15 million  

to 33 million people as states implement national 

health care reforms. baby boomers are expanding 

the senior benefits market at the rate of 10,000 

individuals per day. and the medicaid market is 

expected to grow more than 28 percent to 77 million 

people by 2021. 

about 7 percent of medicaid recipients require 

long-term care. but they account for 35 percent of 

medicaid expenditures. With less than 15 percent 

of these individuals using managed care, there is 

a considerable opportunity to help states improve 

quality and lower cost in long-term care.

about 9 million people, often 

the sickest and poorest, 

rely on both medicare and 

medicaid. the cost of their 

care is estimated to be more 

than $300 billion annually and

12  OVERVIEW

COMPANY OVERVIEWIn the next 10 years, millions more Americans are expected to enter a structured system of health benefit coverage — a system that includes benefits sponsored financially by private sector employers, expanding government programs and, increasingly, by consumers themselves.The demands of this dramatic expansion of health benefits coverage will be a catalyst for major changes and an evolution of the rest of the health care system. The health system will need to become more modern and effective through basic connectivity, better at distributing and using information, more accountable for use of resources and more cost sensitive and efficient.The businesses of UnitedHealth Group are playing key roles in these market-changing trends. Our Health Benefits platform, UnitedHealthcare, is growing by providing innovative, affordable health benefits across the entire spectrum of our customers — consumers, employers and governments. Optum, our Health Services platform, is growing by enabling and directly participating in the evolving modernization, integration and emerging consumerism of  health care delivery.Our businesses are complementary. UnitedHealthcare has the opportunity to pilot new ideas through Optum and to stimulate innovation at Optum by asking for products that fulfill emerging market needs. Optum gains tremendous scale from UnitedHealthcare, which enables it to quickly pilot, perfect and then scale up new offerings. However, Optum and UnitedHealthcare always operate with an “open systems” perspective and business philosophy.UNITEDHEALTH GROUP

Business

OVERVIEW
UnitedHealth Group is a diversified health and well-
being company whose mission is to help people live 
healthier lives and help make health care work better (the 
terms “we,” “our,” “us,” “UnitedHealth Group,” or the 
“Company” used in this report refer to UnitedHealth Group 
Incorporated and our subsidiaries). Our business model has 
evolved and is informed by over three decades of serving 
the needs of the markets, and people, of health care. 

rr

Today, we are helping individuals access quality care at an 

affordable cost; simplifying health care administration and 
delivery; strengthening the physician/patient relationship; 
promoting evidence-based care; and empowering 
physicians, health care professionals, consumers, employers 
and other participants in the health system with actionable 
data to make better, more informed decisions. 

Through our diversified family of businesses, we leverage 

core competencies in advanced, enabling technology;
health care data, information and intelligence; and care 
management and coordination to help meet the demands
of the health system. These core competencies are deployed 
within our two distinct, but strategically aligned, business 
platforms: health benefits operating under UnitedHealthcare 
and health services operating under Optum.

UnitedHealthcare serves the health benefits needs of 
individuals across life’s stages through three businesses. 
UnitedHealthcare Employer & Individual serves individual 
consumers and employers. The unique health needs 
of seniors are served by UnitedHealthcare Medicare & 
Retirement. UnitedHealthcare Community & State serves 
the public health marketplace, offering states innovative 
Medicaid solutions.

Optum serves health system participants including
consumers, physicians, hospitals, governments, insurers, 
distributors and pharmaceutical companies, through its 
OptumHealth, OptumInsight and OptumRx businesses. These 
businesses have dedicated units that drive improved access, 
affordability, quality and simplicity across eight markets: 
integrated care delivery, care management, consumer 
engagement and support, distribution of benefits and
services, health financial services, operational services and 
support, health care information technology and pharmacy.

Through UnitedHealthcare and Optum, in 2011, we 
managed approximately $135 billion in aggregate health 
care spending on behalf of the constituents and consumers 
we served. Our revenues are derived from premiums on 
risk-based products; fees from management, administrative, 
technology and consulting services; sales of a wide variety 
of products and services related to the broad health and 
well-being industry; and investment and other income. Our 
two business platforms have four reportable segments:

The financial results of UnitedHealthcare Employer & 

Individual, UnitedHealthcare Medicare & Retirement, 
and UnitedHealthcare Community & State have been 
aggregated in the UnitedHealthcare reportable segment 
due to their similar economic characteristics, products and 
services, customers, distribution methods, operational 
processes and regulatory environment. These businesses also 
share significant common assets, including our contracted 
networks of physicians, health care professionals, hospitals 
and other facilities, information technology infrastructure 
and other resources. UnitedHealthcare utilizes the 
expertise of UnitedHealth Group affiliates for capabilities 
in specialized areas, such as OptumRx prescription drug 
services, OptumHealth care solutions and behavioral health 
services and OptumInsight fraud and abuse prevention and 
detection. UnitedHealthcare arranges for discounted access 
to care through networks that include a total of nearly 
754,000 physicians and other health care professionals 
and nearly 5,400 hospitals across the United States 
(UnitedHealthcare Network). 

UnitedHealthcare Employer & Individual 
UnitedHealthcare Employer & Individual works closely 
with employers and individuals to provide health 
benefit plans that provide personalized solutions to help 
members live healthier lives and achieve meaningful 
cost savings. UnitedHealthcare Employer & Individual 
offers a comprehensive array of consumer-oriented 
plans and services for large national employers, public 
sector employers, mid-sized employers, small businesses 

2

UNITEDHEALTH GROUP

and individuals nationwide, providing nearly 26 million
Americans access to health care as of December 31, 2011. 

Through its risk-based product offerings, 

UnitedHealthcare Employer & Individual assumes the 
risk of both medical and administrative costs for its 
customers in return for a monthly premium, which is 
typically at a fixed rate per individual served for a one-
year period. When providing administrative and other 
management services to customers that elect to self-fund 
the health care costs of their employees and employees’ 
dependants, UnitedHealthcare Employer & Individual 
receives a fixed service fee per individual served. These 
customers retain the risk of financing medical benefits 
for their employees and employees’ dependants, while 
UnitedHealthcare Employer & Individual provides 
customized services such as coordination and facilitation 
of medical services and related services to customers, 
consumers and health care professionals, transaction 
processing and access to a contracted network of physicians, 
hospitals and other health care professionals, including 
dental and vision. Large employer groups, such as those 
serviced by UnitedHealthcare Employer & Individual 
National Accounts, typically use self-funded arrangements. 
As of December 31, 2011, UnitedHealthcare Employer & 
Individual National Accounts served approximately 400 large 
employer groups under these arrangements, including 147 
of the Fortune 500 companies. Smaller employer groups are 
more likely to purchase risk-based products because they 
are less willing or able to bear a greater potential liability 
for health care expenditures. UnitedHealthcare Employer 
& Individual also offers a variety of non-employer based 
insurance options for purchase by individuals, including
students, which are designed to meet the health coverage 
needs of these consumers and their families. 

As the commercial market becomes more consumer-
oriented, individuals are assuming more personal and 
financial responsibility for their care, and they are 
demanding more affordable products, greater transparency 
and choice and personalized help navigating the complex
system. The consolidated purchasing capacity represented 
by the individuals UnitedHealth Group serves makes it 
possible for UnitedHealthcare Employer & Individual to 
contract for cost-effective access to a large number of 
conveniently located care professionals. Individuals served 
by UnitedHealthcare Employer & Individual have access to 
90% of the physicians and other health care professionals 
and 97% of the hospitals in the UnitedHealthcare Network; 
certain care providers are available only to those consumers 
served through Medicare and/or Medicaid products.

UnitedHealthcare Employer & Individual is engaging

physicians and consumers and using information to 
promote well-informed health decisions, improved medical 
outcomes and greater efficiency. It offers consumers 
engaging and informative tools and resources that provide 
greater transparency around quality and cost, such as 
our Premium Designation program and Treatment Cost 
Estimator tool, affording our members more control over 
their health care. 

UnitedHealthcare Employer & Individual’s innovative 

clinical programs, built around an extensive clinical data set 
and principles of evidence-based medicine, are enabling a
more integrated, proactive and personalized health system. 
The programs promote consumer engagement, health 
education, admission counseling before hospital stays, care 
advocacy to help avoid prolonged patients’ stays in the
hospital, support for individuals at risk of needing intensive 
treatment and coordination of care for people with chronic 
conditions. Disease and condition management programs 
help individuals address significant, complex disease states, 
including disease-specific benefit offerings such as the 
Diabetes Health Plan.

UnitedHealthcare Employer & Individual offers high-
deductible consumer-driven benefit plans, which include
health savings accounts (HSA) and health reimbursement 
accounts (HRA), enabling consumers to achieve even
greater value and choice. During 2011, nearly 36,000 
employer-sponsored benefit plans, including approximately
200 employers in the large group self-funded market, 
purchased one of these consumer-oriented products. 

UnitedHealthcare Employer & Individual’s comprehensive 

and integrated pharmaceutical management services 
promote lower costs by using formulary programs to drive 
better unit costs, encouraging consumers to use drugs that 
offer better value and outcomes, and through physician 
and consumer programs that support the appropriate 
use of drugs based on clinical evidence. In addition,
UnitedHealthcare Employer & Individual also offers a 
comprehensive range of dental, vision, life, and disability 
product offerings delivered through an integrated approach 
that enhances efficiency and effectiveness and includes a 
network of nearly 35,000 vision professionals in private and 
retail settings, and more than 180,000 dental providers.

UnitedHealthcare Employer & Individual’s distribution 
system consists primarily of producers (i.e., brokers and 
agents) and direct and internet sales in the individual 
market, producers in the small employer group market, and 
producers and other consultant-based or direct sales for 
large employer and public sector groups. UnitedHealthcare 
Employer & Individual’s direct distribution efforts are 
generally limited to the individual market, portions of 
the large employer group and public sector markets, and 
cross-selling of specialty products to existing customers. 
UnitedHealthcare Employer & Individual offers its products 
through affiliates that are licensed as insurance companies, 
health maintenance organizations (HMOs), or third party 
administrators (TPAs). 

UnitedHealthcare Medicare & Retirement 
UnitedHealthcare Medicare & Retirement provides health 
and well-being services to individuals age 50 and older,
addressing their unique needs for preventive and acute 
health care services as well as for services dealing with 
chronic disease and other specialized issues for older 
individuals. UnitedHealthcare Medicare & Retirement 
is fully dedicated to serving this growing senior market 
segment, providing products and services in all 50 states, 
the District of Columbia, and most U.S. territories. 

UnitedHealthcare Medicare & Retirement offers a 

wide spectrum of Medicare products, including Medicare 
Advantage plans, Medicare Part D prescription drug 
coverage, and Medigap products that supplement 
traditional fee-for-service coverage, which may be sold 
to individuals or on a group basis. Premium revenues 
from the Centers for Medicare & Medicaid Services (CMS) 
represented 28% of our total consolidated revenues for 
the year ended December 31, 2011, most of which were 
generated by UnitedHealthcare Medicare & Retirement 
under a number of contracts. 

UnitedHealthcare Medicare & Retirement has extensive 

distribution capabilities and experience, including direct 
marketing to consumers on behalf of its key clients: 
AARP, the nation’s largest membership organization 
dedicated to the needs of people age 50 and over; state 
and U.S. government agencies; and employer groups. 
UnitedHealthcare Medicare & Retirement also has distinct 
pricing, underwriting, clinical program management and 
marketing capabilities dedicated to risk-based health 
products and services in the senior and geriatric markets. 

Medicare Advantage. UnitedHealthcare Medicare & 
Retirement provides health care coverage for seniors 
and other eligible Medicare beneficiaries primarily 
through the Medicare Advantage program administered 
by CMS, including Medicare Advantage HMO plans, 
preferred provider organization (PPO) plans, Special 
Needs Plans, Point-of-Service (POS) plans and Private-
Fee-for-Service plans. Under the Medicare Advantage 
programs, UnitedHealthcare Medicare & Retirement 
provides health insurance coverage in exchange for a 
fixed monthly premium per member from CMS. Premium 
amounts vary based on the geographic areas in which 
members reside; demographic factors such as age, gender, 
and institutionalized status; and the health status of the 
individual.  UnitedHealthcare Medicare & Retirement 
also provides complete, individualized care planning and 
care benefits for retirees, aging, disabled and chronically 
ill individuals, serving individuals enrolled in Medicare 
Advantage products in 30 states and in the District of 
Columbia in long-term care settings including nursing 
homes, community-based settings and private homes. 
In addition, UnitedHealthcare Medicare & Retirement 
offers innovative care management and clinical programs, 
integrating federal, state and personal funding through 
a continuum of products from Medicare Advantage and 
Special Needs Plans to hospice care. For high-risk patients 
in certain care settings and programs, UnitedHealthcare 
Medicare & Retirement uses proprietary, automated 
medical record software that enables clinical care teams 
to capture and track patient data and clinical encounters, 
creating a comprehensive set of care information that 
bridges across home, hospital and nursing home care 
settings. UnitedHealthcare Medicare & Retirement had 
approximately 2.2 million members enrolled in its Medicare 
Advantage products as of December 31, 2011. Proprietary 
predictive modeling tools help identify members at high 
risk and allow care managers to proactively outreach to 

2011 FORM 10-K

members to create individualized care plans and help 
members obtain the right care, in the right place, at the 
right time.

Prescription Drug Benefit (Part D). UnitedHealthcare 
Medicare & Retirement provides the Medicare prescription 
drug benefit (Part D) to beneficiaries throughout the 
United States and its territories. UnitedHealthcare Medicare 
& Retirement provides Part D drug coverage through its 
Medicare Advantage program and stand-alone Part D 
plans. As of December 31, 2011, UnitedHealthcare Medicare 
& Retirement had enrolled 7.1 million members in the Part 
D program, including 4.9 million members in the stand-
alone Part D plans and 2.2 million members in its Medicare 
Advantage plans incorporating Part D coverage. 

Medicare Supplement. In association with AARP, 
UnitedHealthcare Medicare & Retirement provides a range 
of Medicare supplement and hospital indemnity insurance 
offerings through insurance company affiliates to 3.8 
million AARP members. 

Additional UnitedHealthcare Medicare & Retirement 
services include a nurse health line service, a lower cost 
Medicare supplement offering that provides consumers 
with a national hospital network, 24-hour access to health 
care information, and access to discounted health services 
from a network of physicians.

UnitedHealthcare Community & State 
UnitedHealthcare Community & State is dedicated to 
providing innovative Medicaid managed care solutions 
to states that care for the economically disadvantaged, 
the medically underserved and those without the benefit 
of employer-funded health care coverage in exchange 
for a monthly premium per member from the applicable 
state. States using managed care services for Medicaid 
beneficiaries select health plans using either a formal bid 
process, or award individual contracts. As of December 31, 
2011, UnitedHealthcare Community & State participates in 
programs in 23 states and the District of Columbia, serving 
approximately 3.5 million beneficiaries of acute and long-
term care Medicaid plans, the Children’s Health Insurance 
Program (CHIP), Special Needs Plans and other federal and 
state health care programs. 

UnitedHealthcare Community & State’s health plans and 
care programs are designed to address the complex needs 
of the populations they serve, including the chronically 
ill, those with disabilities and people with higher risk 
medical, behavioral and social conditions. UnitedHealthcare 
Community & State leverages the national capabilities of 
UnitedHealth Group, delivering them at the local market 
level to support effective care management, strong 
regulatory partnerships, greater administrative efficiency, 
improved clinical outcomes and the ability to adapt 
to a changing market environment. UnitedHealthcare 
Community & State coordinates resources among family, 
physicians, other health care providers, and government 
and community-based agencies and organizations to 
facilitate continuous and effective care. For example, the 
Personal Care Model establishes an ongoing relationship 

4

UNITEDHEALTH GROUP

between health care professionals and individuals who
have serious and chronic health conditions to help them
maintain the best possible health and functional status, 
whether care is delivered in an acute care setting, long-
term care facility or at home. Programs for families and 
children focus on high-prevalence and debilitating chronic
illnesses such as hypertension and cardiovascular disease, 
asthma, sickle cell disease, diabetes, HIV/AIDS and high-risk 
pregnancies. Programs for the long-term care population 
focus on dementia, depression, coronary disease and 
functional-use deficiencies that impede daily living.

The breadth of this portfolio allows Optum to impact 

key activities that help enable better integrated, more 
sustainable health care. 

OPTUMHEALTH
OptumHealth serves the physical, emotional and 
financial needs of 60 million unique individuals, enabling
consumer health management and collaborative care 
delivery through programs offered by employers, payers, 
government entities and, increasingly, directly through the 
care delivery system. OptumHealth’s products and services 
can be deployed individually or integrated to provide
comprehensive solutions, addressing a broad base of needs 
within the health care system. OptumHealth’s solutions 
reduce costs for customers, improve workforce productivity 
and consumer satisfaction and optimize the overall health 
and well-being of populations.

OptumHealth’s simple, modular service designs can 
be easily integrated to meet varying employer, payer, 
government entity, care provider and consumer needs 
at a wide range of price points. OptumHealth offers 
its products, primarily, on an administrative fee basis 
whereby it manages or administers delivery of the product 
or services in exchange for a fixed fee per individual 
served, and on a risk basis, where OptumHealth assumes 
responsibility for health care costs in exchange for a fixed 
monthly premium per individual served. For its financial 
services offerings, OptumHealth charges fees and earns 
investment income on managed funds.

OptumHealth sells its products primarily through its direct 

sales force, strategic collaborations and external producers 

in three markets: employers (which includes the sub-
markets of large, mid and small employers), payers (which 
includes the sub-markets of health plans, TPAs, underwriter/
stop-loss carriers and individual market intermediaries) 
and government entities (which includes States, CMS, 
Department of Defense, Veterans Administration and other 
federal procurement). As provider reimbursement models 
evolve, care providers are emerging as a fourth market 
segment for our health management, financial services and 
collaborative care services.

OptumHealth is organized into five major operating 

groups: Care Solutions, Behavioral Solutions, Financial
Services, Collaborative Care, and Logistics Health, Inc.

Care Solutions. Care Solutions serves more than 41 million 
individuals through personalized health management (e.g.,
wellness, chronic and complex conditions), decision support
(e.g., insurance choices, treatment and health care provider 
options) and access to networks of care provider specialists 
linked to medical conditions with high variation of quality
and cost (e.g., physical health, cancer and transplants). 
This comprehensive solution set empowers consumers and 
enables their collaboration with specialty care providers that 
is critical to decisions that drive hospitalization and surgery. 

Behavioral Solutions. Behavioral Solutions serves more than 
52 million individuals through global well-being solutions
(e.g., employee assistance programs) and behavioral health 
management solutions (e.g., mental health, substance 
abuse) that address the emotional health needs of 
consumers, spanning the stress and anxiety of daily living, 
to depression associated with chronic illness, to clinically 
diagnosed mental illness. Programs combine predictive 
modeling, evidence-based clinical outcomes management,
consumer support and peer support, with access to a 
leading network of behavioral health care providers. 
Behavioral Solutions customers have access to a national 
network of more than 112,000 clinicians and counselors and
3,300 facilities in approximately 6,600 locations nationwide. 

Financial Services. Dedicated solely to the health care 
market, OptumHealth Financial Services helps organizations 
and individuals optimize their health care finances. As a 
leading provider of consumer health care accounts (e.g.,
health savings accounts, flexible spending accounts),
OptumHealth Financial Services enables people to use 
those tax-favored accounts to save money today and build
health savings for the future. Organizations rely upon 
OptumHealth Financial Services to manage and improve 
their cash flows through turnkey electronic payment 
solutions (e.g., remittance advices, funds transfers) health 
care-related lending and credit (e.g., financing of care
provider medical equipment) and financial risk protection 
for third party payers and self-funded employers (e.g., 
comprehensive stop-loss insurance coverage).

Financial Services is comprised of OptumHealth Bank, 

which is a member of the Federal Deposit Insurance 
Corporation (FDIC), a TPA and a transaction processing
service for the health care industry. As of December 31, 
2011, Financial Services had $1.5 billion in customer assets 

under management and during 2011 processed $54 billion 
in medical payments to physicians and other health
care providers. 

Collaborative Care. Working closely with various health 
care providers in local markets and communities, 
Collaborative Care believes that the market is moving 
to a collaborative network model aligned around total 
population health management and outcomes-based 
reimbursement. In close coordination with local integrated 
care delivery systems, it deploys a core set of technology, 
risk management, analytical and clinical capabilities 
and tools to assist physicians in delivering high-quality 
care across the populations they serve. OptumHealth’s 
coordinated post-acute care services augment primary 
care physicians to deliver services outside of hospitals to 
vulnerable, chronically ill populations. In affiliation with 
a broad variety of payers, Collaborative Care also delivers 
care to approximately 700,000 people through a spectrum 
of models ranging from medical clinics to contracts with 
individual practice association networks. 

Logistics Health, Inc. Acquired in 2011, Logistics Health, Inc. 
(LHI) focuses on mobile care delivery, logistically arranging 
for convenient access to care at the time and place most 
needed. LHI designs and implements occupational health, 
medical and dental readiness services, treatments and 
immunization programs and disability exams for the 
U.S. Military, Veterans Administration and Department 
of Health and Human Services, as well as numerous 
commercial companies. Services are delivered in provider 
clinics or through temporary on-site resources.

through a direct sales force. OptumInsight’s products are also 
supported and distributed through an array of alliance and
business partnerships with other technology vendors, who

are offered through four integrated market groups. These

hospitals), Payer, Government and Life Sciences.

Provider. The Provider market group combines a 
comprehensive range of technology and information 
products, advisory consulting, and outsourcing services 
focused on hospitals, integrated delivery networks, and 
physician practices. These solutions help providers establish

of patient reported outcomes to inform comparative 
effectiveness research, patient engagement and 
adherence, and population health management.

Many of OptumInsight’s software and information 

products, advisory consulting arrangements, and 
outsourcing contracts are performed over an extended 
period, often several years. OptumInsight maintains an 
order backlog to track unearned revenues under these 
long-term arrangements. The backlog consists of estimated 
revenue from signed contracts, other legally binding 
agreements and anticipated contract renewals based on 
historical experience that either have not started but are 
anticipated to begin in the near future, or are in process 
and have not been completed. In 2011, OptumInsight
standardized backlog reporting across recent acquisitions 
and as a result increased the backlog by $0.4 billion. 
OptumInsight’s aggregate backlog at December 31, 
2011 was $4.0 billion, of which $2.4 billion is expected
to be realized within the next 12 months. This includes 
$0.9 billion related to intersegment agreements, all of 
which are included in the current portion of the backlog.
OptumInsight cannot provide any assurance that it will be 
able to realize all of the revenues included in backlog due
to uncertainty regarding the timing and scope of services, 
the potential for cancellation, non-renewal, or early 
termination of service arrangements.

health insurance brokers and other health care consultants 
and direct sales. 

GOVERNMENT REGULATION 

Most of our health and well-being services are regulated by 
federal and state regulatory agencies that generally have 
discretion to issue regulations and interpret and enforce 
laws and rules. These regulations can vary significantly 
from jurisdiction to jurisdiction, and the interpretation of 
existing laws and rules also may change periodically. In the 
first quarter of 2010, the Patient Protection and Affordable 
Care Act and a reconciliation measure, the Health Care 
and Education Reconciliation Act of 2010, which we refer 
to together as the Health Reform Legislation, were signed 
into law. The Health Reform Legislation, portions of which 
are summarized below, alters the regulatory environment 
in which we operate, in some cases to a significant degree. 
Federal and state governments continue to enact and 
consider various legislative and regulatory proposals that 
could materially impact certain aspects of the health care 
system. New laws, regulations and rules, or changes in the 
interpretation of existing laws, regulations and rules, as 
well as a result of changes in the political climate, could 
adversely affect our business. 

In the event we fail to comply with, or we fail to respond 

quickly and appropriately to changes in, applicable laws, 
regulations and rules, our business, results of operations, 
financial position and cash flows could be materially 
and adversely affected. See Item 1A, “Risk Factors” for a 
discussion of the risks related to compliance with federal 
and state laws and regulations. 

HEALTH CARE REFORMS
The Health Reform Legislation expands access to coverage 
and modifies aspects of the commercial insurance market, 
as well as the Medicaid and Medicare programs, CHIP and 
other aspects of the health care system. Certain provisions 
of the Health Reform Legislation have already taken effect, 
and other provisions become effective at various dates over 
the next several years. The U.S. Department of Health and 
Human Services (HHS), the U.S. Department of Labor (DOL) 
and the U.S. Treasury Department have issued or proposed 
regulations on a number of aspects of Health Reform 
Legislation, but final rules and interim guidance on other 
key aspects of the legislation remain pending. 

Certain aspects of the Health Reform Legislation are also 

being challenged in federal court, with the proponents 
of such challenges seeking to limit the scope of or have 
all or portions of the Health Reform Legislation declared 
unconstitutional. The United States Supreme Court is 
scheduled to hear oral arguments on certain aspects of 
these cases in March 2012, including the constitutionality 
of the individual mandate. Congress may also withhold 
the funding necessary to implement the Health Reform 
Legislation, or may attempt to replace the legislation with 
amended provisions or repeal it altogether.

The following outlines certain provisions of the Health 
Reform Legislation that have recently taken effect or are 
expected to take effect in the coming years, assuming the 
legislation is implemented in its current form. 

2011 FORM 10-K

7

Effective 2010: The Health Reform Legislation mandated: 
the expansion of dependent coverage to include adult 
children until age 26; eliminated certain annual and 
lifetime caps on the dollar value of certain essential health 
benefits; eliminated pre-existing condition limits for 
enrollees under age 19; prohibited certain policy rescissions; 
prohibited plans and issuers from charging higher cost 
sharing (copayments or coinsurance) for emergency services 
that are obtained out of a plan’s network; and included a 
requirement to provide coverage for preventive services 
without cost to members (for non-grandfathered plans). 
The Health Reform Legislation also mandated certain 
changes to coverage determination and appeals processes, 
including: expanding the definition of “adverse benefit 
determination” to include rescissions; extending external 
review rights of adverse benefit determinations to insured 
and self-funded plans; and improving the clarity of and 
expanding the types of information in adverse benefit 
determination notices. 

Effective 2011: Commercial fully insured health plans in the 
large employer group, small employer group and individual 
markets with medical loss ratios below certain targets (85% 
for large employer groups, 80% for small employer groups 
and 80% for individuals, as calculated under the definitions 
in the Health Reform Legislation and regulations, subject 
to state specific exceptions) are required to rebate ratable 
portions of their premiums to their customers annually. 
Rebate payments for 2011 will be made in mid 2012. 
A state can request a waiver of the individual market 
medical loss ratio for up to three years if the state petitions 
and provides to HHS certain supporting data, and HHS 
determines that the requirement is disruptive to the market 
in that state. By the end of 2011, 17 states petitioned HHS 
for waivers of the mandated individual market medical 
loss ratio, of which six were wholly or partially granted. 
The Health Reform Legislation also mandated consumer 
discounts of 50% on brand name prescription drugs 
and 7% on generic prescription drugs for Part D plan 
participants in the coverage gap. These consumer discounts 
will gradually increase over the next several years, which 
will decrease consumer out-of-pocket drug spending within 
the coverage gap, shifting a portion of these costs to the 
plan sponsor.

In addition, as required under the Health Reform 

Legislation, HHS established a federal premium rate review 
process, which became effective in September 2011 and 
generally applies to proposed rate increases equal to 
or exceeding 10% (with state-specific thresholds to be 
applicable commencing September 2012). The regulations 
further require commercial health plans to provide to the 
states and HHS extensive information supporting any rate 
increases subject to the new federal rate review process. 
The regulations clarify that HHS review will not supersede 
existing state review and approval processes, but plans 
deemed to have a history of “unreasonable” rate increases 
may be prohibited from participating in the state-based 
exchanges that become active under the Health Reform 
Legislation in 2014. Under the regulations, the HHS rate

review process would apply only to health plans in the
individual and small group markets.

Effective 2011/2012:  CMS reduced or froze benchmarks 
which affect our Medicare Advantage reimbursements 
from CMS between 2009 and 2011, and beginning in 2012,
additional cuts to Medicare Advantage benchmarks will 
take effect (benchmarks will ultimately range from 95% of 
Medicare fee-for-service rates in high cost areas to 115% in 
low cost areas), with changes being phased-in over two to
six years, depending on the level of benchmark reduction
in a county. In addition to other measures, quality 
bonuses may partially offset these anticipated benchmark 
reductions as CMS quality rating bonuses are phased in over
three years beginning in 2012. 

Effective 2013: Effective beginning in 2013 with 
respect to services performed after 2009, the Health 
Reform Legislation limits the deductibility of executive 
compensation under Section 162(m) of the Internal 
Revenue Code for insurance providers if at least 25% of 
the insurance provider’s gross premium income from health 
business is derived from health insurance plans that meet 
the minimum creditable coverage requirements. 

Effective 2013/2014: The Health Reform Legislation 
provides for an increase in Medicaid fee-for-service and 
managed care program reimbursements for primary care 
services provided by primary care doctors (family medicine, 
general internal medicine or pediatric medicine) to 100% 
of the Medicare payment rates for 2013 and 2014, and 
provides 100% federal financing for the difference in rates 
based on rates applicable on July 1, 2009. 

Effective 2014: A number of the provisions of the Health 
Reform Legislation are scheduled to take effect in 2014, 
including: an annual insurance industry assessment ($8 
billion levied on the insurance industry in 2014 with
increasing annual amounts thereafter), which is not 
deductible for income tax purposes; expansion of Medicaid
eligibility for all individuals and families with incomes up 
to 133% of the federal poverty level (states can early adopt 
the expansion without increased federal funding prior to
2014) with states receiving full federal matching in 2014 
through 2016; all individual and group health plans must
offer coverage on a guaranteed issue and guaranteed 
renewal basis during annual open enrollment and special
enrollment periods and cannot apply pre-existing condition
exclusions or health status rating adjustments; elimination 
of annual limits on essential benefits coverage on certain 
plans; establishment of state-based exchanges for 
individuals and small employers (generally, with up to 100
employees) as well as certain CHIP eligibles; introduction 
of plan designs based on set actuarial values to increase 
comparability of competing products on the exchanges;
and establishment of minimum medical loss ratio of 85% 
for Medicare Advantage plans, as calculated under rules 
that have not yet been issued. 

The Health Reform Legislation and the related federal 
and state regulations will impact how we do business and

could restrict revenue and enrollment growth in certain 
products and market segments, restrict premium growth 
rates for certain products and market segments, increase 
our medical and administrative costs, expose us to an 
increased risk of liability (including increasing our liability 
in federal and state courts for coverage determinations 
and contract interpretation) or put us at risk for loss of 
business. In addition, our results of operations, financial 
position, including our ability to maintain the value of our
goodwill, and cash flows could be materially and adversely
affected by such changes. The Health Reform Legislation 
may also create new or expand existing opportunities for 
business growth, but due to its complexity, the impact of 
the Health Reform Legislation remains difficult to predict 
and is not yet fully known. See also Item 1A, “Risk Factors” 
for a discussion of the risks related to the Health Reform 
Legislation and related matters. 

OTHER FEDERAL LAWS AND REGULATION
We are subject to various levels of federal regulation. For 
example, when we contract with the federal government, 
we are subject to federal laws and regulations relating 
to the award, administration and performance of U.S. 
government contracts. CMS regulates our UnitedHealthcare 
Medicare & Retirement and UnitedHealthcare Community & 
State Medicare and Medicaid businesses, as well as certain 
aspects of our Optum businesses. Our UnitedHealthcare 
Medicare & Retirement and UnitedHealthcare Community 
& State businesses submit information relating to the 
health status of enrollees to CMS (or state agencies) for 
purposes of determining the amount of certain payments 
to us. CMS also has the right to audit performance to 
determine compliance with CMS contracts and regulations 
and the quality of care given to Medicare beneficiaries. See 
Note 12 of Notes to the Consolidated Financial Statements 
and risk factors in this Form 10-K for a discussion of audits 
by CMS.

Our UnitedHealthcare reporting segment, through 
UnitedHealthcare Community & State, also has Medicaid 
and CHIP contracts that are subject to federal regulations 
regarding services to be provided to Medicaid enrollees, 
payment for those services and other aspects of these 
programs. There are many regulations surrounding 
Medicare and Medicaid compliance, and the regulatory
environment with respect to these programs has become 
and will continue to become increasingly complex as a
result of the Health Reform Legislation. In addition, certain 
of Optum’s businesses hold contracts with federal agencies, 
including the U.S. Department of Defense, and we are 
subject to federal law and regulations relating to the 
administration of these contracts. 

Certain of UnitedHealthcare’s and Optum’s businesses, 

such as UnitedHealthcare’s eyeglass manufacturing 
activities and Optum’s high clinical acuity workflow 
software, hearing aid products, and clinical research 
activities, are subject to regulation by the U.S. Food and 
Drug Administration, and the clinical research activities are 
also subject to laws and regulations outside of the United 
States that regulate clinical trials. Laws and regulations 

relating to consumer protection, anti-fraud and abuse, anti-
kickbacks, false claims, prohibited referrals, inappropriately 
reducing or limiting health care services, anti-money 
laundering, securities and antitrust also affect us. 

HIPAA, GLBA and Other Privacy and Security Regulation. 
The administrative simplification provisions of the 
Health Insurance Portability and Accountability Act of 
1996, as amended (HIPAA), apply to both the group and 
individual health insurance markets, including self-funded 
employee benefit plans. HIPAA requires guaranteed health 
care coverage for small employers and certain eligible 
individuals. It also requires guaranteed renewability for 
employers and individuals and limits exclusions based 
on pre-existing conditions. Federal regulations related 
to HIPAA include minimum standards for electronic 
transactions and code sets, and for the privacy and security 
of protected health information. The HIPAA privacy 
regulations do not preempt more stringent state laws and 
regulations that may also apply to us. 

Federal privacy and security requirements change 

frequently because of legislation, regulations and judicial 
or administrative interpretation. For example, the U.S. 
Congress enacted the American Recovery and Reinvestment 
Act of 2009 (ARRA), which significantly amends, and 
adds new privacy and security provisions to HIPAA and 
imposes additional requirements on uses and disclosures 
of health information. ARRA includes new contracting 
requirements for HIPAA business associate agreements; 
extends parts of HIPAA privacy and security provisions 
to business associates; adds new federal data breach 
notification requirements for covered entities and business 
associates and new reporting requirements to HHS and 
the Federal Trade Commission (FTC) and, in some cases, 
to the local media; strengthens enforcement and imposes 
higher financial penalties for HIPAA violations and, in 
certain cases, imposes criminal penalties for individuals, 
including employees. We are awaiting final regulations 
on many key aspects of the ARRA amendments to HIPAA. 
In the conduct of our business, we may act, depending on 
the circumstances, as either a covered entity or a business 
associate. Federal consumer protection laws may also apply 
in some instances to privacy and security practices related 
to personal identifiable information. The use and disclosure 
of individually identifiable health data by our businesses 
is also regulated in some instances by other federal laws, 
including the Gramm-Leach-Bliley Act (GLBA) or state 
statutes implementing GLBA, which generally require 
insurers to provide customers with notice regarding how 
their non-public personal health and financial information 
is used and the opportunity to “opt out” of certain 
disclosures before the insurer shares such information with 
a third party, and which generally require safeguards for 
the protection of personal information. See Item 1A, “Risk 
Factors” for a discussion of the risks related to compliance 
with HIPAA, GLBA and other privacy-related regulations. 

ERISA. The Employee Retirement Income Security Act 
of 1974, as amended (ERISA), regulates how goods 

2011 FORM 10-K

9

and services are provided to or through certain types 
of employer-sponsored health benefit plans. ERISA is a 
set of laws and regulations that is subject to periodic 
interpretation by the DOL as well as the federal courts. 
ERISA places controls on how our business units may do 
business with employers who sponsor employee benefit 
health plans, particularly those that maintain self-funded 
plans. Regulations established by the DOL provide 
additional rules for claims payment and member appeals 
under health care plans governed by ERISA. Additionally, 
some states require licensure or registration of companies 
providing third-party claims administration services for 
health care plans. 

FDIC. The FDIC has federal regulatory authority over 
OptumHealth Bank and performs annual examinations 
to ensure that the bank is operating in accordance with 
federal safety and soundness requirements. In addition 
to such annual examinations, the FDIC performs periodic 
examinations of the bank’s compliance with applicable 
federal banking statutes, regulations and agency 
guidelines. In the event of unfavorable examination 
results, the bank could be subject to increased operational 
expenses and capital requirements, governmental
oversight and monetary penalties. 

STATE LAWS AND REGULATION
Health Care Regulation. Our insurance and HMO 
subsidiaries must be licensed by the jurisdictions in which 
they conduct business. All of the states in which our 
subsidiaries offer insurance and HMO products regulate 
those products and operations. These states require 
periodic financial reports and establish minimum capital or 
restricted cash reserve requirements. With the amendment 
of the Annual Financial Reporting Model Regulation by the 
National Association of Insurance Commissioners (NAIC) 
to adopt elements substantially similar to the Sarbanes-
Oxley Act of 2002, we expect that these states will continue 
to expand the scope of regulations relating to corporate 
governance and internal control activities of HMOs and 
insurance companies. Certain states have also adopted 
their own regulations for minimum medical loss ratios with 
which health plans must comply. In addition, a number 
of state legislatures have enacted or are contemplating 
significant reforms of their health insurance markets, either 
independent of or to comply with or be eligible for grants 
or other incentives in connection with the Health Reform 
Legislation. We expect the states to continue to introduce 
and pass similar laws in 2012, and this will affect our 
operations and our financial results. 

Health plans and insurance companies are also regulated 

under state insurance holding company regulations. Such 
regulations generally require registration with applicable 
state departments of insurance and the filing of reports 
that describe capital structure, ownership, financial 
condition, certain intercompany transactions and general 
business operations. Some state insurance holding company 
laws and regulations require prior regulatory approval of 
acquisitions and material intercompany transfers of assets, 

10

UNITEDHEALTH GROUP

as well as transactions between the regulated companies 
and their parent holding companies or affiliates. These laws 
may restrict the ability of our regulated subsidiaries to pay 
dividends to our holding companies.

In addition, some of our business and related activities 
may be subject to other health care-related regulations and 
requirements, including PPO, managed care organization
(MCO), utilization review (UR) or third-party administrator-
related regulations and licensure requirements. These 
regulations differ from state to state, and may contain 
network, contracting, product and rate, and financial and
reporting requirements. There are laws and regulations 
that set specific standards for delivery of services, payment 
of claims, adequacy of health care professional networks, 
fraud prevention, the protection of consumer health 
information, pricing and underwriting practices and 
covered benefits and services. State health care anti-
fraud and abuse prohibitions encompass a wide range
of activities, including kickbacks for referral of members, 
billing unnecessary medical services and improper 
marketing. Certain of our businesses are subject to state 
general agent, broker, and sales distributions laws and 
regulations. Our UnitedHealthcare Community & State 
and UnitedHealthcare Medicare & Retirement businesses 
are subject to regulation by state Medicaid agencies that 
oversee the provision of benefits to our Medicaid and 
CHIP beneficiaries and to our dually-eligible Medicaid
beneficiaries. We also contract with state governmental 
entities and are subject to state laws and regulations 
relating to the award, administration and performance of 
state government contracts. 

Guaranty Fund Assessments. Under state guaranty fund 
laws, certain insurance companies (and HMOs in some 
states), including those issuing health, long-term care, 
life and accident insurance policies, doing business in
those states can be assessed (up to prescribed limits) for 
certain obligations to the policyholders and claimants of 
insolvent insurance companies that write the same line 
or lines of business. Assessments generally are based on a 
formula relating to premiums in the state compared to the 
premiums of other insurers and could be spread out over 
a period of years. Some states permit member insurers to 
recover assessments paid through full or partial premium 
tax offsets. See Note 12 of Notes to the Consolidated 
Financial Statements for a discussion of a matter involving 
Penn Treaty Network American Insurance Company and its 
subsidiary (Penn Treaty), which have been placed 
in rehabilitation. 

Pharmacy Regulation. OptumRx’s mail order pharmacies 
must be licensed to do business as pharmacies in the states 
in which they are located. Our mail order pharmacies 
must also register with the U.S. Drug Enforcement 
Administration and individual state controlled substance 
authorities to dispense controlled substances. In many 
of the states where our mail order pharmacies deliver 
pharmaceuticals there are laws and regulations that require 
out-of-state mail order pharmacies to register with that 

state’s board of pharmacy or similar regulatory body. These 
states generally permit the pharmacy to follow the laws 
of the state in which the mail order pharmacy is located, 
although some states require that we also comply with 
certain laws in that state. Our mail order pharmacies 
maintain certain Medicare and state Medicaid provider 
numbers as pharmacies providing services under these 
programs. Participation in these programs requires the 
pharmacies to comply with the applicable Medicare and 
Medicaid provider rules and regulations. Other laws and 
regulations affecting our mail order pharmacies include 
federal and state statutes and regulations governing 
the labeling, packaging, advertising and adulteration of
prescription drugs and dispensing of controlled substances. 
See Item 1A, “Risk Factors” for a discussion of the risks 
related to our PBM businesses. 

Privacy and Security Laws. States have adopted regulations
to implement provisions of the GLBA. Like HIPAA, GLBA
allows states to adopt more stringent requirements
governing privacy protection. A number of states have
also adopted other laws and regulations that may affect
our privacy and security practices, for example, state laws 
that govern the use, disclosure and protection of social
security numbers and sensitive health information or that
are designed to protect credit card account data. State and
local authorities increasingly focus on the importance of
protecting individuals from identity theft, with a significant
number of states enacting laws requiring businesses to
notify individuals of security breaches involving personal
information. State consumer protection laws may also
apply to privacy and security practices related to personally
identifiable information, including information related
to consumers and care providers. Additionally, different
approaches to state privacy and insurance regulation and
varying enforcement philosophies in the different states may
materially and adversely affect our ability to standardize our 
products and services across state lines. See Item 1A, “Risk 
Factors” for a discussion of the risks related to compliance 
with state privacy and security-related regulations.

UDFI. The Utah State Department of Financial Institutions 
(UDFI) has state regulatory and supervisory authority 
over OptumHealth Bank and in conjunction with federal
regulators performs annual examinations to ensure that 
the bank is operating in accordance with state safety 
and soundness requirements. In addition to such annual
examinations, the UDFI in conjunction with federal regulators 
performs periodic examinations of the bank’s compliance 
with applicable state banking statutes, regulations and 
agency guidelines. In the event of unfavorable examination
results, the bank could be subjected to increased operational 
expenses and capital requirements, governmental oversight 
and monetary penalties. 

Corporate Practice of Medicine and Fee-Splitting Laws. 
Certain of our businesses function as direct service 
providers to care delivery systems and, as such, are subject 
to additional laws and regulations. Some states have 
corporate practice of medicine laws that prohibit certain 

2011 FORM 10-K

11

and consulting companies. For our UnitedHealthcare 
businesses, competitors include Aetna Inc., Cigna 
Corporation, Coventry Health Care, Inc., Health Net, Inc., 
Humana Inc., Kaiser Permanente, WellPoint, Inc., numerous 
for-profit and not-for-profit organizations operating under 
licenses from the Blue Cross Blue Shield Association and 
other enterprises that serve more limited geographic areas. 
For our OptumRx businesses, competitors include Medco 
Health Solutions, Inc., CVS Caremark Corporation and 
Express Scripts, Inc. Our OptumHealth and OptumInsight 
reportable segments also compete with a broad and 
diverse set of businesses. New entrants into the markets in 
which we compete, as well as consolidation within these 
markets, also contribute to a competitive environment. 
We believe the principal competitive factors that can 
impact our businesses relate to the sales, marketing and 
pricing of our products and services; product innovation; 
consumer satisfaction; the level and quality of products and 
services; care delivery; network capabilities; market share; 
product distribution systems; efficiency of administration 
operations; financial strength and marketplace reputation. 
If we fail to compete effectively to maintain or increase 
our market share, including maintaining or increasing 
enrollments in businesses providing health benefits, our 
results of operations, financial position and cash flows 
could be materially and adversely affected. See Item 1A, 
“Risk Factors,” for additional discussion of our risks related 
to competition. 

EMPLOYEES

As of December 31, 2011, we employed approximately 
99,000 individuals. We believe our employee relations are 
generally positive. 

entities from practicing medicine or employing physicians 
to practice medicine. Additionally, some states prohibit 
certain entities from sharing in the fees or revenues of a 
professional practice (fee-splitting). These prohibitions may 
be statutory or regulatory, or may be a matter of judicial 
or regulatory interpretation. These laws, regulations and 
interpretations have, in certain states, been subject to 
limited judicial and regulatory interpretation and are 
subject to change.

Consumer Protection Laws. Certain businesses participate 
in direct-to-consumer activities and are subject to emerging 
regulations applicable to on-line communications and other 
general consumer protection laws and regulations.

AUDITS AND INVESTIGATIONS
We have been and are currently involved in various 
governmental investigations, audits and reviews. These 
include routine, regular and special investigations, 
audits and reviews by CMS, state insurance and health 
and welfare departments, state attorneys general, the 
Office of the Inspector General, the Office of Personnel 
Management, the Office of Civil Rights, the FTC, U.S. 
Congressional committees, the U.S. Department of Justice, 
U.S. Attorneys, the SEC, the Internal Revenue Service (IRS), 
the DOL, the FDIC and other governmental authorities. 
Such government actions can result in assessment of 
damages, civil or criminal fines or penalties, or other 
sanctions, including loss of licensure or exclusion from 
participation in government programs. See Note 12 of 
Notes to the Consolidated Financial Statements for details. 
In addition, disclosure of any adverse investigation, audit 
results or sanctions could adversely affect our reputation in 
various markets and make it more difficult for us to sell our 
products and services and retain our current business. 

INTERNATIONAL REGULATION
Most of our business is conducted in the United States. 
However, some of our businesses and operations are 
international in nature and are consequently subject to 
regulation in the jurisdictions in which they are organized 
or conduct business. These regulatory regimes encompass 
tax, licensing, tariffs, intellectual property, investment, 
management control, anti-fraud, anti-corruption and 
privacy and data protection regulations (including 
requirements for cross-border data transfers) that vary from
jurisdiction to jurisdiction, among other matters. These 
international operations are also subject to United States 
laws that regulate activities of U.S.-based businesses abroad.

COMPETITION

As a diversified health and well-being services company, 
we operate in highly competitive markets. Our competitors 
include managed health care companies, insurance 
companies, HMOs, TPAs and business services outsourcing 
companies, health care professionals that have formed 
networks to directly contract with employers or with CMS, 
specialty benefit providers, government entities, disease 
management companies, and various health information

ITEM 1A. Risk Factors 

CAUTIONARY STATEMENTS
The statements, estimates, projections, guidance or outlook 
contained in this Annual Report on Form 10-K include 
forward-looking statements within the meaning of the 
Private Securities Litigation Reform Act of 1995 (PSLRA). 
When used in this Annual Report on Form 10-K and in 
future filings by us with the SEC, in our news releases, 
presentations to securities analysts or investors, and in 
oral statements made by or with the approval of one of 
our executive officers, the words or phrases “believe,” 
“expect,” “intend,” “estimate,” “anticipate,” “plan,” 
project,” “should” or similar expressions are intended to 
identify such forward-looking statements. These statements 
are intended to take advantage of the “safe harbor” 
provisions of the PSLRA. These forward-looking statements 
involve risks and uncertainties that may cause our actual 
results to differ materially from the results discussed in the
forward-looking statements.

The following discussion contains certain cautionary 

statements regarding our business that investors and 
others should consider. We do not undertake to address 
or update forward-looking statements in future filings 
or communications regarding our business or results of 
operations, and do not undertake to address how any 
of these factors may have caused results to differ from
discussions or information contained in previous filings 
or communications. In addition, any of the matters 
discussed below may have affected past, as well as current, 
forward-looking statements about future results. Any 
or all forward-looking statements in this Form 10-K and 
in any other public filings or statements we make may 
turn out to be wrong. They can be affected by inaccurate 
assumptions we might make or by known or unknown 
risks and uncertainties. Many factors discussed below 
will be important in determining future results. By their 
nature, forward-looking statements are not guarantees 
of future performance or results and are subject to risks, 
uncertainties and assumptions that are difficult to predict 
or quantify. Actual future results may vary materially  
from expectations expressed in this report or any of our 
prior communications.

If we fail to effectively estimate, price for and manage our 
medical costs, the profitability of our risk-based products 
and services could decline and could materially and 
adversely affect our results of operations, financial position 
and cash flows. 

Under our risk-based benefit product arrangements, we 
assume the risk of both medical and administrative costs for 
our customers in return for monthly premiums. Premium 
revenues from risk-based benefits products comprise 
approximately 90% of our total consolidated revenues. We 
generally use approximately 80% to 85% of our premium 
revenues to pay the costs of health care services delivered 
to these customers. The profitability of these products 
depends in large part on our ability to predict, price for, 
and effectively manage medical costs. In this regard, the 

14

UNITEDHEALTH GROUP

Health Reform Legislation established minimum medical 
loss ratios for certain health plans, and authorized HHS 
to maintain an annual review process of “unreasonable” 
increases in premiums for commercial health plans. In 
addition, a number of states have enhanced (or are 
proposing to enhance) their premium review and approval
processes. See the risk factor below relating to health care 
reform for further discussion of these provisions.

We manage medical costs through underwriting criteria,
product design, negotiation of favorable provider contracts
and care management programs. Total medical costs are
affected by the number of individual services rendered
and the cost of each service. Our premium revenue on 
commercial policies is typically at a fixed rate per individual 
served for a 12-month period and is generally priced one to
four months before the contract commences. Our revenue on
Medicare policies is based on bids submitted in June the year
before the contract year. We base the premiums we charge
and our Medicare bids on our estimates of future medical
costs over the fixed contract period; however, medical cost
inflation, regulation and other factors may cause actual costs 
to exceed what was estimated and reflected in premiums
or bids. These factors may include increased use of services, 
increased cost of individual services, catastrophes, epidemics, 
the introduction of new or costly treatments and technology,
new mandated benefits (such as the expansion of essential
benefits coverage) or other regulatory changes, insured
population characteristics and seasonal changes in the level
of health care use. As a measure of the impact of medical 
costs on our financial results, relatively small differences 
between predicted and actual medical costs or utilization
rates as a percentage of revenues can result in significant 
changes in our financial results. For example, if medical
costs increased by 1% without a proportional change in 
related revenues for commercial insured products our
annual net earnings for 2011 would have been reduced by 
approximately $215 million, excluding any offsetting impact
from premium rebates.

In addition, the financial results we report for any 
particular period include estimates of costs that have 
been incurred for which claims are still outstanding. These 
estimates involve an extensive degree of judgment. If these 
estimates prove too low, our results of operations could be 
materially and adversely affected. 

Our business activities are highly regulated; new laws 
or regulations or changes in existing laws or regulations
or their enforcement or application could materially and 
adversely affect our results of operations, financial position
and cash flows. 

Our business is regulated at the federal, state, local and 

international levels. Our insurance and HMO subsidiaries 
must be licensed by and are subject to the regulations 
of the jurisdictions in which they conduct business. For 
example, states require periodic financial reports and 
enforce minimum capital or restricted cash reserve 
requirements. Health plans and insurance companies are 
also regulated under state insurance holding company
regulations, and some of our activities may be subject to 

other health care-related regulations and requirements, 
including those relating to PPOs, MCOs, utilization review 
and TPA-related regulations and licensure requirements. 
Some of our businesses hold or provide services related 
to government contracts and are subject to federal 
and state anti-kickback and other laws and regulations 
governing government contractors. See Item 1, “Business - 
Government Regulation” for further information.
The laws and rules governing our business and 
interpretations of those laws and rules are subject to
frequent change. For example, in the first quarter of
2010, the Health Reform Legislation was signed into law,
legislating broad-based changes to the U.S. health care
system. See Item 1, “Business - Government Regulation”
for a discussion of the Health Reform Legislation. The
broad latitude that is given to the agencies administering
regulations governing our business, as well as future laws
and rules, and interpretation and enforcement of those
laws and rules by governmental enforcement authorities,
could force us to change how we do business, restrict
revenue and enrollment growth, increase our health care
and administrative costs and capital requirements, and
increase our liability in federal and state courts for coverage 
determinations, contract interpretation and other actions.
We must also obtain and maintain regulatory approvals 

to market many of our products, to increase prices for 
certain regulated products and to complete certain 
acquisitions and dispositions, including integration of
certain acquisitions. For example, premium rates for our 
health insurance and/or managed care products are subject 
to regulatory review or approval in many states, and a 
number of states have enhanced (or are proposing to 
enhance) their rate review processes. Delays in obtaining 
necessary approvals or our failure to obtain or maintain 
adequate approvals could materially and adversely affect 
our revenues, results of operations, financial position and 
cash flows. 

Under state guaranty fund laws, certain insurance 
companies (and HMOs in some states), including those 
issuing health (which includes long-term care), life and
accident insurance policies, doing business in those
states can be assessed (up to prescribed limits) for certain 
obligations to the policyholders and claimants of insolvent 
insurance companies that write the same line or lines 
of business. Changes in these laws or the interpretation 
thereof, or insolvency by another insurer, could have 
a material adverse effect on our results of operations, 
financial position and cash flows. See Note 12 of Notes to 
the Consolidated Financial Statements in this Form 10-K 
for a discussion of a matter involving an unaffiliated entity, 
Penn Treaty, which has been placed in rehabilitation.

Certain Optum businesses are also subject to regulatory 

and other risks and uncertainties in addition to the risks 
of our businesses of providing managed care and health
insurance products. For example, state corporate practice 
of medicine doctrines and fee-splitting rules can impact 
our relationships with physicians, hospitals and customers. 
OptumHealth is subject to state telemedicine laws and 

regulations that apply to its telemedicine initiatives. 
Additionally, OptumHealth participates in the emerging 
private exchange markets and it is not yet known to what 
extent the states will issue new regulations that apply 
to private exchanges. These risks and uncertainties may 
materially and adversely affect our ability to market our 
products and services, or to do so at targeted margins, or 
increase the regulatory burdens under which we operate. 

We are also involved in various governmental 

investigations, audits and reviews. See Note 12 of Notes 
to the Consolidated Financial Statements in this Form 10-K 
for a discussion of certain of these matters. See also the 
risk factor below relating to our activities as a payer in 
various government health care programs for a discussion 
of audits by CMS. Reviews and investigations of this sort 
can lead to government actions, which can result in the 
assessment of damages, civil or criminal fines or penalties, 
or other sanctions, including restrictions or changes in the 
way we conduct business, loss of licensure or exclusion 
from participation in government programs, and could 
have a material adverse effect on our results of operations, 
financial position and cash flows.

The health care industry is also regularly subject 
to negative publicity, including as a result of routine 
governmental investigations, the political debate 
surrounding the Health Reform Legislation and the 
political environment in general. Negative publicity may 
adversely affect our stock price, damage our reputation in 
various markets, foster an increasingly active regulatory 
environment or result in increased regulation and 
legislative review of industry practices. This may further 
increase our costs of doing business and the regulatory 
burdens under which we operate.

Some of our businesses and operations are international 
in nature and consequently face political, economic, legal, 
compliance, regulatory, operational and other risks and 
exposures that are unique and vary by jurisdiction. The 
regulatory environments and associated requirements 
and uncertainties regarding tax, licensing, tariffs, 
intellectual property, privacy, data protection, investment, 
management control, fraud and anti-corruption present 
additional challenges for us beyond those faced by U.S.-
based businesses. Such requirements and uncertainties may 
adversely affect our ability to market our products and 
services, or to do so at targeted margins, or increase the 
regulatory burdens under which we operate.

For a discussion of various laws and regulations that 
impact our businesses, see Item 1, “Business - Government 
Regulation.”

The enactment or implementation of health care reforms 
could materially and adversely affect the manner in 
which we conduct business and our results of operations, 
financial position and cash flows. 

In the first quarter of 2010, the Health Reform Legislation 

was signed into law. The Health Reform Legislation 
expands access to coverage and modifies aspects of the 
commercial insurance market, as well as the Medicaid and 
Medicare programs and CHIP and other aspects of the 

2011 FORM 10-K

15

health care system. Among other things, the Health Reform 
Legislation includes guaranteed coverage and expanded 
benefit requirements, eliminates pre-existing condition 
exclusions and annual and lifetime maximum limits, restricts 
the extent to which policies can be rescinded, establishes 
minimum medical loss ratios, creates a federal premium 
review process, imposes new requirements on the format 
and content of communications (such as explanations 
of benefits, or EOBs) between health insurers and their 
members, grants to members new and additional appeal 
rights, imposes new and significant taxes on health insurers 
and health care benefits, reduces the Medicare Part D 
coverage gap and reduces payments to private plans 
offering Medicare Advantage. 

Certain provisions of the Health Reform Legislation have 
already taken effect, and other provisions become effective 
at various dates over the next several years. HHS, the DOL 
and the Treasury Department have issued or proposed 
regulations on a number of aspects of Health Reform 
Legislation, but final rules and interim guidance on other 
key aspects of the legislation remain pending. Due to the 
complexity of the Health Reform Legislation, the impact of 
the Health Reform Legislation remains difficult to predict 
and is not yet fully known. 

For example, effective in 2011, the Health Reform 
Legislation established minimum medical loss ratios for 
all commercial health plans in the large employer group, 
small employer group and individual markets (85% for 
large employer groups, 80% for small employer groups 
and 80% for individuals, calculated under the definitions 
in the Health Reform Legislation and regulations). 
Companies with medical loss ratios below these targets 
are required to rebate ratable portions of their premiums 
to their customers annually. The potential for and size of 
the rebates will be measured by state, by group size and 
by licensed subsidiary. This disaggregation of insurance 
pools into much smaller pools will likely decrease the 
predictability of results for any given pool and could lead 
to variation over time in the estimates of rebates owed in 
total. Effective in 2014, Medicare Advantage plans will be 
required to maintain a minimum medical loss ratio of 85%. 
Depending on the results of these calculations and the 
manner in which we adjust our business model in light of 
these requirements, there could be meaningful disruptions 
in local health care markets, and our market share, 
revenues, results of operations, financial position and cash 
flows could be materially and adversely affected.

In addition, the Health Reform Legislation requires the 
establishment of state-based health insurance exchanges 
for individuals and small employers by 2014. The types 
of exchange participation requirements ultimately 
enacted by each state, the availability of federal premium 
subsidies within exchanges, the potential for differential 
imposition of state benefit mandates inside and outside 
the exchanges, the operation of reinsurance, risk corridors 
and risk adjustment mechanisms inside and outside the 
exchanges and the possibility that certain states may restrict 
the ability of health plans to continue to offer coverage to 

16

UNITEDHEALTH GROUP

individuals and small employers outside of the exchanges, 
could result in disruptions in local health care markets and 
our revenues, results of operations, financial position and 
cash flows could be materially and adversely affected.

The Health Reform Legislation includes a “maintenance 
of effort” (MOE) provision that requires states to maintain 
their eligibility rules for people covered by Medicaid, 
until the Secretary of HHS determines that an insurance 
exchange is operational in a given state. The MOE provision 
is intended to prevent states from reducing eligibility 
standards and determination procedures as a way to 
remove adults above 133% of the federal poverty level from 
Medicaid before implementation of expanded Medicaid 
coverage effective in January 2014. However, states with, or 
projecting, a budget deficit may apply for an exception to 
the MOE provision. If states are successful in obtaining MOE 
waivers and allow certain Medicaid programs to expire, we 
could experience reduced Medicaid enrollment, which could
materially and adversely affect our revenues, results of 
operations, financial position and cash flows.

Several of the provisions in the Health Reform 

Legislation will likely increase our medical cost trends. 
Examples of these provisions are the excise tax on medical 
devices, annual fees on prescription drug manufacturers, 
enhanced coverage requirements (including discounted
prescription drugs for Medicare Part D participants) and 
the prohibition of pre-existing condition exclusions. The
annual insurance industry assessment ($8 billion levied 
on the insurance industry in 2014 with increasing annual
amounts thereafter), which is not deductible for income 
tax purposes, will increase our operating costs. Premium 
increases will be necessary to offset the impact these and 
other provisions will have on our medical and operating
costs. These premium increases are oftentimes subject 
to state regulatory approval. In this regard, the Federal 
government is encouraging states to intensify their 
reviews of requests for rate increases by commercial health 
plans and providing funding to assist in those state-level 
reviews. We have begun to experience greater regulatory 
challenges to appropriate premium rate increases in 
several states, including California, New York and Rhode 
Island. In addition, as required under the Health Reform 
Legislation, HHS established a federal premium rate review 
process, which became effective in September 2011 and 
generally applies to proposed rate increases equal to 
or exceeding 10% (with state-specific thresholds to be 
applicable commencing September 2012). The regulations 
further require commercial health plans in the individual 
and small group markets to provide to the states and HHS 
extensive information supporting any rate increases subject 
to the new federal rate review process. If we are not able 
to secure approval for adequate premium increases to 
offset increases in our cost structure, our revenues, results 
of operations, financial position and cash flows could
be materially and adversely affected. In addition, plans 
deemed to have a history of “unreasonable” rate increases 
may be prohibited from participating in the state-based 
exchanges that become active under the Health Reform 

Legislation in 2014. Under the regulations, the HHS rate 
review process would apply only to health plans in the
individual and small group markets.

The Congressional Budget Office has estimated that up 
to 34 million new individuals may eventually gain insurance
coverage if the Health Reform Legislation is implemented 
broadly in its current form. In addition, we expect that 
implementation of the Health Reform Legislation will 
increase the demand for products and capabilities offered 
by our Optum businesses. We have made and will continue
to make strategic decisions and investments based, in 
part, on these assumptions, and our results of operations, 
financial position and cash flows could be materially and
adversely affected if fewer individuals gain coverage 
under the Health Reform Legislation than estimated or 
we are unable to attract these new individuals to our 
UnitedHealthcare offerings, or if the demand for our 
Optum businesses does not increase. 

Certain aspects of the Health Reform Legislation are also 

being challenged in federal court, with the proponents
of such challenges seeking to limit the scope of or have 
all or portions of the Health Reform Legislation declared 
unconstitutional. The United States Supreme Court is 
scheduled to hear oral arguments on certain aspects of 
these cases in March 2012, including the constitutionality 
of the individual mandate. Congress may withhold the
funding necessary to implement the Health Reform 
Legislation, or may attempt to replace the legislation with 
amended provisions or repeal it altogether. Any partial 
or complete repeal or amendment or implementation 
difficulties, or uncertainty regarding such events, could 
materially and adversely impact our ability to capitalize 
on the opportunities presented by the Health Reform 
Legislation or may cause us to incur additional costs 
of compliance. For example, if the individual mandate 
is declared unconstitutional or repealed without 
corresponding changes to other provisions of the Health
Reform Legislation to protect against the risk of adverse 
selection (such as revisions to the guaranteed issue 
and renewal requirements, prohibition on pre-existing
condition exclusions, and rating restrictions), our results 
of operations, financial position and cash flows could be
materially and adversely affected. 

Congress is also considering additional health care 

reform measures, and a number of state legislatures have 
enacted or are contemplating significant reforms of their 
health insurance markets, either independent of or to 
comply with or be eligible for grants or other incentives in 
connection with the Health Reform Legislation. The effects 
of the Health Reform Legislation and recently adopted 
state laws, and the regulations that have been and will 
be promulgated thereunder, are difficult to predict, and 
we cannot predict whether any other federal or state 
proposals will ultimately become law. Such laws and rules 
could force us to materially change how we do business,
restrict revenue and enrollment growth in certain products 
and market segments, restrict premium growth rates for 
certain products and market segments, adversely change 

the nature of our contracted network relationships, 
increase our medical and administrative costs and capital 
requirements, expose us to an increased risk of liability 
(including increasing our liability in federal and state courts 
for coverage determinations and contract interpretation) 
or put us at risk for loss of business. In addition, our market 
share, our results of operations, our financial position, 
including our ability to maintain the value of our goodwill, 
and our cash flows could be materially and adversely 
affected by such changes. 

For additional information regarding the Health Reform 
Legislation, see Item 1, “Business - Government Regulation” 
and Item 7, “Management’s Discussion and Analysis of 
Financial Condition and Results of Operations - Executive 
Overview - Regulatory Trends and Uncertainties.” 

As a result of our participation in various government 

health care programs, both as a payer and as a service 
provider to payers, we are exposed to additional risks 
associated with program funding, enrollments, payment 
adjustments and audits that could materially and adversely 
affect our revenues, results of operations, financial 
position and cash flows. 

We participate in various federal, state and local 

government health care coverage programs, including as 
a payer in Medicare Advantage, Medicare Part D, various 
Medicaid programs and CHIP, and receive substantial 
revenues from these programs. We also provide services 
to payers through our Optum businesses. These programs 
generally are subject to frequent changes, including 
changes that may reduce the number of persons enrolled or 
eligible for coverage, reduce the amount of reimbursement 
or payment levels, reduce our participation in certain 
service areas or markets, or increase our administrative
or medical costs under such programs. For example, 
CMS reduced or froze Medicare Advantage benchmarks 
that drive reimbursements between 2009 and 2011, and 
beginning in 2012, additional cuts to Medicare Advantage 
benchmarks will take effect, with changes being phased-in 
over two to six years, depending on the level of benchmark 
reduction in a county. Although we have adjusted 
members’ benefits and premiums on a selective basis, 
terminated benefit plans in certain counties, and intensified 
both our medical and operating cost management in 
response to these benchmark reductions, there can be 
no assurance that we will be able to execute successfully 
on these or other strategies to address changes in the 
Medicare Advantage program. 

As part of the Health Reform Legislation, CMS has
developed a system whereby a plan that meets certain 
quality ratings will be entitled to various quality bonus 
payments. There can be no assurance that any of our plans 
will meet these quality ratings. Our revenues, results of 
operations, financial position and cash flows could be
materially and adversely affected by funding reductions, 
or if our plans do not meet the requirements to receive 
quality bonus payments. Similarly, any reduction in Medicare 
Advantage payments could result in downward pressure
on payments made to our Collaborative Care business in

2011 FORM 10-K

17

exchange for services provided to Medicare Advantage plans.
Our participation in the Medicare Advantage, Medicare 

Part D, and various Medicaid and CHIP programs occurs 
through bids that are submitted periodically. Revenues for 
these programs are dependent upon periodic funding from 
the federal government or applicable state governments 
and allocation of the funding through various payment 
mechanisms. Funding for these government programs 
is dependent upon many factors outside of our control, 
including general economic conditions and budgetary 
constraints at the federal or applicable state level, and 
general political issues and priorities. A reduction or 
less than expected increase, or a protracted delay, in 
government funding for these programs or change in 
allocation methodologies may materially and adversely 
affect our revenues, results of operations, financial position 
and cash flows. State Medicaid programs are also imposing 
other reforms, such as medical loss ratio requirements 
on Medicaid managed care organizations, which 
generally require such plans to rebate ratable portions 
of their premiums to their state customers if they cannot 
demonstrate they have met the ratio standards.

CMS uses various payment mechanisms to allocate 
funding for Medicare programs, including adjusting 
monthly capitation payments to Medicare Advantage 
plans and Medicare Part D plans according to the predicted 
health status of each beneficiary as supported by data 
from health care providers as well as, for Medicare Part 
D plans only, based on comparing costs predicted in our 
annual bids to actual prescription drug costs. Some state 
Medicaid programs utilize a similar process. For example, 
our UnitedHealthcare Medicare & Retirement and 
UnitedHealthcare Community & State businesses submit 
information relating to the health status of enrollees to 
CMS or state agencies for purposes of determining the 
amount of certain payments to us. In 2008, CMS announced 
that it will perform risk adjustment data validation 
(RADV) audits of selected Medicare health plans each 
year to validate the coding practices of and supporting 
documentation maintained by health care providers, and 
certain of our local plans have been selected for audit. 
These audits may result in retrospective adjustments to 
payments made to our health plans. In December 2010, 
CMS published for public comment a new proposed RADV 
audit and payment adjustment methodology. The proposed 
methodology contains provisions allowing retroactive 
contract level payment adjustments for the year audited 
using an extrapolation of the “error rate” identified in 
audit samples. In February 2011, CMS announced that it 
would be making changes to the proposed methodology 
based, in part, on comments submitted by industry 
participants. As of the date of this filing, CMS has not 
published the revised methodology. Depending on the 
methodology utilized, potential payment adjustments 
could have a material adverse effect on our results of 
operations, financial position and cash flows. 

In addition, the Office of Inspector General for HHS has 
audited our risk adjustment data for two local plans and 

18

UNITEDHEALTH GROUP

has initially communicated its findings, although we cannot
predict the final outcome of the audit process. Any payment
adjustments required as a result of the audits or otherwise 
could have a material adverse effect on our results of
operations, financial position and cash flows. See Note 12 of
Notes to the Consolidated Financial Statements in this Form
10-K for additional information regarding these audits.

CMS conducts a variety of routine, regular and special 
investigations, audits and reviews across the industry. For 
example, in the fourth quarter of 2011, CMS conducted an 
audit of our Medicare Advantage and Part D business. We 
are in the process of responding to preliminary findings. 
As with any CMS review, in the event we fail to comply 
with applicable CMS and state laws, regulations and rules, 
our results of operations, financial position and cash flows 
could be materially and adversely affected.

Under the Medicaid Managed Care program, state 

Medicaid agencies are periodically required by federal law 
to seek bids from eligible health plans to continue their 
participation in the acute care Medicaid health programs. 
If we are not successful in obtaining renewals of state 
Medicaid Managed Care contracts, we risk losing the 
members that were enrolled in those Medicaid plans. Under
the Medicare Part D program, to qualify for automatic 
enrollment of low income members, our bids must result in 
an enrollee premium below a regional benchmark, which
is calculated by the government after all regional bids 
are submitted. If the enrollee premium is not below the 
government benchmark, we risk losing the members who 
were auto-assigned to us and we will not have additional
members auto-assigned to us. For example, we lost 
approximately 470,000 of our auto-enrolled low-income
subsidy members effective January 1, 2012, because certain 
of our bids exceeded thresholds set by the government. 
In general, our bids are based upon certain assumptions 
regarding enrollment, utilization, medical costs, and 
other factors. In the event any of these assumptions are 
materially incorrect, either as a result of unforeseen 
changes to the Medicare program or other programs on 
which we bid, or our competitors submit bids at lower rates 
than our bids, our results of operations, financial position 
and cash flows could be materially and adversely affected. 

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

The collection, maintenance, protection, use, 
transmission, disclosure and disposal of sensitive 
personal information are regulated at the federal, state, 
international and industry levels and requirements are 
imposed on us by contracts with customers. These laws, 
rules and requirements are subject to change. Further, 
many of our businesses are subject to the Payment Card 
Industry Data Security Standards (PCI DSS), which is a 

multifaceted security standard that is designed to protect 
credit card account data as mandated by payment card 
industry entities. See Item 1, “Business - Government 
Regulation” for additional information. HIPAA also requires 
business associates as well as covered entities to comply 
with certain privacy and security requirements. Even 
though we provide for appropriate protections through
our contracts with our third-party service providers and 
in certain cases assess their security controls, we still have 
limited oversight or control over their actions and practices. 
Our facilities and systems and those of our third-party 
service providers may be vulnerable to privacy and security 
incidents; security attacks and breaches; acts of vandalism 
or theft; computer viruses; coordinated attacks by activist 
entities; emerging cybersecurity risks; misplaced or lost 
data; programming and/or human errors; or other similar 
events. Emerging and advanced security threats, including 
coordinated attacks, require additional layers of security 
which may disrupt or impact efficiency of operations. 

Compliance with new laws, regulations and requirements 

may result in increased operating costs, and may constrain
our ability to manage our business model. For example, 
our ability to collect, disclose and use sensitive personal
information may be further restricted, and we are awaiting
final HHS regulations for many key aspects of the ARRA
amendments to HIPAA, such as with regard to marketing,
electronic health records and access reports (which may
necessitate system changes). In addition, HHS has announced
a pilot audit program to assess HIPAA compliance efforts by 
covered entities through 2012. Although we are not aware 
of HHS plans to audit any of our covered entities, an audit
resulting in findings or allegations of noncompliance could 
have a material adverse effect on our results of operations, 
financial position and cash flows.

Noncompliance or findings of noncompliance with 

applicable laws, regulations or requirements, or the 
occurrence of any privacy or security breach involving the
misappropriation, loss or other unauthorized disclosure of
sensitive personal information, whether by us or by one
of our third-party service providers, could have a material
adverse effect on our reputation, results of operations,
financial position and cash flows, including the following 
consequences: mandatory disclosure of a privacy or security
breach to the media; significant increases in the cost of
managing and remediating privacy or security incidents;
enforcement actions; material fines and penalties; an impact 
on our ability to process credit card transactions as well as 
an increase in related expenses; litigation; compensatory,
special, punitive, and statutory damages; consent orders
regarding our privacy and security practices; adverse actions 
against our licenses to do business; and injunctive relief.

Our businesses providing PBM services face regulatory 
and other risks and uncertainties associated with the PBM 
industry that may differ from the risks of our business of 
providing managed care and health insurance products.
We provide PBM services through our OptumRx and 
UnitedHealthcare businesses. Each business is subject to 
federal and state anti-kickback and other laws that govern 

their relationships with pharmaceutical manufacturers, 
customers and consumers. In addition, federal and state 
legislatures regularly consider new regulations for the 
industry that could materially and adversely affect current 
industry practices, including the receipt or disclosure of 
rebates from pharmaceutical companies, the development 
and use of formularies, and the use of average wholesale 
prices. See Item 1, “Business - Government Regulation” 
for a discussion of various federal and state laws and 
regulations governing our PBM businesses. 

OptumRx also conducts business as a mail order pharmacy 

and specialty pharmacy, which subjects it to extensive 
federal, state and local laws and regulations. The failure 
to adhere to these laws and regulations could expose 
OptumRx to civil and criminal penalties. 

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

sponsors of health benefit plans that are subject to ERISA. 
The DOL, which is the agency that enforces ERISA, could 
assert that the fiduciary obligations imposed by the 
statute apply to some or all of the services provided by our 
PBM businesses even where our PBM businesses are not 
contractually obligated to assume fiduciary obligations. 
In the event a court were to determine that fiduciary 
obligations apply to our PBM businesses in connection with 
services for which our PBM businesses are not contractually 
obligated to assume fiduciary obligations, we could be 
subject to claims for breaches of fiduciary obligations or 
entering into certain prohibited transactions.

UnitedHealthcare Employer & Individual is transitioning 

pharmacy benefit management for approximately 12 
million of its commercial members, including pharmacy 
claims adjudication and customer service, from Medco 
Health Solutions, Inc. to OptumRx beginning in 2013. 
If we are unable to execute the transition effectively, 
UnitedHealthcare Employer & Individual could face loss 
of business, which could adversely impact our results of 
operations, financial position and cash flows.

If we fail to compete effectively to maintain or increase 
our market share, including maintaining or increasing 
enrollments in businesses providing health benefits, our 
results of operations, financial position and cash flows 
could be materially and adversely affected. 

Our businesses compete throughout the United States 
and face significant competition in all of the geographic 
markets in which we operate. We compete with other 
companies on the basis of many factors, including price of 

2011 FORM 10-K

19

benefits offered and cost and risk of alternatives, location 
and choice of health care providers, quality of customer 
service, comprehensiveness of coverage offered, reputation 
for quality care, financial stability and diversity of product 
offerings. For our UnitedHealthcare reporting segment, 
competitors include Aetna Inc., Cigna Corporation, 
Coventry Health Care, Inc., Health Net, Inc., Humana Inc., 
Kaiser Permanente, WellPoint, Inc., numerous for-profit and 
not-for-profit organizations operating under licenses from 
the BlueCross BlueShield Association and other enterprises 
that serve more limited geographic areas or market 
segments such as Medicare and Medicaid specialty services. 
For our OptumRx business, competitors include Medco 
Health Solutions, Inc., CVS/Caremark Corporation and 
Express Scripts, Inc. Our OptumHealth and OptumInsight 
reporting segments also compete with a broad and diverse 
set of businesses.

In particular markets, competitors may have greater
capabilities, resources or market share; a more established
reputation; superior supplier or health care professional 
arrangements; existing business relationships; or other 
factors that give such competitors a competitive advantage. 
In addition, significant merger and acquisition activity 
has occurred in the industries in which we operate, both 
as to our competitors and suppliers (including hospitals, 
physician groups and other care professionals) in these 
industries. Consolidation may make it more difficult for us 
to retain or increase customers, to improve the terms on
which we do business with our suppliers, or to maintain or 
increase profitability. If we do not compete effectively in 
our markets, if we set rates too high or too low in highly 
competitive markets, if we do not design and price our 
products properly and competitively, if we are unable to 
innovate and deliver products and services that demonstrate 
value to our customers, if we do not provide a satisfactory 
level of services, if membership or demand for other 
services does not increase as we expect, if membership or 
demand for other services declines, or if we lose accounts 
with more profitable products while retaining or increasing 
membership in accounts with less profitable products, our 
business,  results of operations, financial position and cash 
flows could be materially and adversely affected. 

If we fail to develop and maintain satisfactory relationships 
with physicians, hospitals, and other health care providers, 
our business could be materially and adversely affected. 
We contract with physicians, hospitals, pharmaceutical 
benefit service providers, pharmaceutical manufacturers, 
and other health care providers for services. Our results 
of operations and prospects are substantially dependent 
on our continued ability to contract for these services 
at competitive prices. Failure to develop and maintain 
satisfactory relationships with health care providers, 
whether in-network or out-of-network, could materially 
and adversely affect our business, results of operations, 
financial position and cash flows.

In any particular market, physicians and health care 

providers could refuse to contract, demand higher 
payments, or take other actions that could result in higher 

20

UNITEDHEALTH GROUP

medical costs, less desirable products for customers or 
difficulty meeting regulatory or accreditation requirements. 
In some markets, certain health care providers, particularly 
hospitals, physician/hospital organizations or multi-specialty 
physician groups, may have significant market positions or 
near monopolies that could result in diminished
bargaining power on our part. In addition, physician
or practice management companies, which aggregate 
physician practices for administrative efficiency and 
marketing leverage, may compete directly with us. If these 
providers refuse to contract with us, use their market 
position to negotiate favorable contracts or place us at a 
competitive disadvantage, our ability to market products 
or to be profitable in those areas could be materially and 
adversely affected. 

In addition, we have capitation arrangements with 

some physicians, hospitals and other health care providers. 
Under the typical capitation arrangement, the health care 
provider receives a fixed percentage of premiums to cover 
all or a defined portion of the medical costs provided to the 
capitated member. Under some capitated arrangements, 
the provider may also receive additional compensation 
from risk sharing and other incentive arrangements. 
Capitation arrangements limit our exposure to the risk of 
increasing medical costs, but expose us to risk related to 
the adequacy of the financial and medical care resources 
of the health care provider. To the extent that a capitated 
health care provider organization faces financial difficulties 
or otherwise is unable to perform its obligations under 
the capitation arrangement, we may be held responsible 
for unpaid health care claims that should have been 
the responsibility of the capitated health care provider 
and for which we have already paid the provider under
the capitation arrangement. Further, payment or other 
disputes between a primary care provider and specialists 
with whom the primary care provider contracts can result 
in a disruption in the provision of services to our members 
or a reduction in the services available to our members. 
There can be no assurance that health care providers 
with whom we contract will properly manage the costs of 
services, maintain financial solvency or avoid disputes with 
other providers. Any of these events could have a material 
adverse effect on the provision of services to our members 
and our operations. 

Some providers that render services to our members 
do not have contracts with us. In those cases, we do not 
have a pre-established understanding about the amount
of compensation that is due to the provider for services 
rendered to our members. In some states, the amount of 
compensation due to these out-of-network providers is 
defined by law or regulation, but in most instances, it is 
either not defined or it is established by a standard that 
does not clearly specify dollar terms. In some instances, 
providers may believe that they are underpaid for their 
services and may either litigate or arbitrate their dispute 
with us or try to recover from our members the difference 
between what we have paid them and the amount they
charged us. For example, we are involved in litigation 

with out-of-network providers, as described in more 
detail in “Litigation Matters” in Note 12 of Notes to the 
Consolidated Financial Statements. 

Accountable care organizations (ACOs) and other

organizational structures that physicians, hospitals, and 
other care providers choose may change the way that these 
providers interact with us and may change the competitive 
landscape. These changes may affect the way that we price 
our products and estimate our costs and may require us 
to incur costs to change our operations, and our results 
of operations, financial position and cash flows could be
adversely affected. 

The success of certain Optum businesses depends on 

maintaining satisfactory physician relationships. The primary 
care physicians that practice medicine or contract with our 
affiliated physician organizations could terminate their 
provider contracts or otherwise become unable or unwilling 
to continue practicing medicine or contracting with us. If 
we are unable to maintain satisfactory relationships with 
primary care physicians, or to retain enrollees following 
the departure of a physician, our revenues could be 
materially and adversely affected. In addition, our affiliated 
physician organizations contract with health insurance and 
HMO competitors of UnitedHealthcare. If our affiliated 
physician organizations fail to maintain relationships with 
these health insurance or HMO companies, our results 
of operations, financial position and cash flows could be
materially and adversely affected. 

In addition, physicians, hospitals, pharmaceutical 

benefit service providers, pharmaceutical manufacturers, 
and certain health care providers are customers of our 
Optum businesses. Given the importance of health care 
providers and other constituents to our businesses, failure 
to maintain satisfactory relationships with them could 
materially and adversely affect our results of operations, 
financial position and cash flows.

Sales of our products and services are dependent on our
ability to attract, retain and provide support to a network 
of independent producers and consultants.

Our products are sold in part through independent
producers and consultants who assist in the production 
and servicing of business. We typically do not have long-
term contracts with our producers and consultants, who 
generally are not exclusive to us and who typically also 
recommend and/or market health care products and 
services of our competitors. As a result, we must compete 
intensely for their services and allegiance. Our sales would 
be materially and adversely affected if we are unable to 
attract or retain independent producers and consultants 
or if we do not adequately provide support, training and
education to them regarding our product portfolio, or
if our sales strategy is not appropriately aligned across 
distribution channels. 

Because producer commissions are included as 
administrative expenses under the medical loss ratio
requirements of the Health Reform Legislation, these
expenses will be under the same cost reduction pressures as
other administrative costs. Our relationships with producers

could be materially and adversely impacted by changes in 
our business practices and the nature of our relationships to 
address these pressures, including potential reductions 
in commissions.

In addition, there have been a number of investigations 

regarding the marketing practices of producers selling 
health care products and the payments they receive. These 
have resulted in enforcement actions against companies 
in our industry and producers marketing and selling 
these companies’ products. For example, CMS and state 
departments of insurance have increased their scrutiny of 
the marketing practices of producers who market Medicare 
products. These investigations and enforcement actions 
could result in penalties and the imposition of corrective 
action plans, which could materially and adversely impact 
our ability to market our products. 

Our relationship with AARP is important and the loss of 
such relationship could have an adverse effect on our 
business and results of operations. 

Under our agreements with AARP, we provide AARP-

branded Medicare Supplement insurance, hospital 
indemnity insurance and other products and services to 
AARP members under a Supplement Health Insurance 
Program (the AARP Program). We also provide AARP-
branded Medicare Advantage and Medicare Part D 
prescription drug plans to both AARP members and 
non-members. Our agreements with AARP extend to 
December 31, 2017 for the AARP Program and December 
31, 2014 for the Medicare Advantage and Medicare Part D 
offerings. Our agreements with AARP contain commitments 
regarding corporate governance, corporate social 
responsibility, diversity and measures intended to improve 
and simplify the health care experience for consumers. The 
AARP agreements may be terminated early under certain 
circumstances, including, depending on the agreement, a 
material breach by either party, insolvency of either party, a 
material adverse change in our financial condition, material 
changes in the Medicare programs, material harm to AARP 
caused by us, and by mutual agreement. The success of 
our AARP arrangements depends, in part, on our ability to 
service AARP and its members, develop additional products 
and services, price the products and services competitively, 
meet our corporate governance, corporate social 
responsibility, and diversity commitments, and respond 
effectively to federal and state regulatory changes. The loss 
of our AARP relationship could have an adverse effect on 
our business and results of operations. 

Because of the nature of our business, we are routinely 
subject to various litigation actions, which could damage 
our reputation and, if resolved unfavorably, could result 
in substantial penalties and/or monetary damages and 
materially and adversely affect our results of operations, 
financial position and cash flows.

Because of the nature of our business, we are routinely 
made party to a variety of legal actions related to, among 
other things, the design, management and delivery of our 
product and service offerings. These matters have included 

2011 FORM 10-K

21

or could in the future include claims related to health care 
benefits coverage and payment (including disputes with 
enrollees, customers, and contracted and non-contracted 
physicians, hospitals and other health care professionals), 
tort (including claims related to the delivery of health care 
services), contract disputes and claims related to disclosure 
of certain business practices. We are also party to certain 
class action lawsuits brought by health care professional 
groups and consumers. We are largely self-insured with 
regard to litigation risks. Although we maintain excess 
liability insurance with outside insurance carriers for claims 
in excess of our self-insurance, certain types of damages, 
such as punitive damages in some circumstances, are not 
covered by insurance. We record liabilities for our estimates 
of the probable costs resulting from self-insured matters; 
however, it is possible that the level of actual losses will 
significantly exceed the liabilities recorded. 

A description of significant legal actions in which we 

are currently involved is included in Note 12 of Notes 
to the Consolidated Financial Statements. We cannot 
predict the outcome of these actions with certainty, and 
we are incurring expenses in resolving these matters. 
The legal actions we face or may face in the future could 
further increase our cost of doing business and materially 
and adversely affect our results of operations, financial 
position and cash flows. In addition, certain legal actions 
could result in adverse publicity, which could damage our 
reputation and materially and adversely affect our ability 
to retain our current business or grow our market share in 
select markets and businesses.

Unfavorable economic conditions could materially
and adversely affect our revenues and our results  
of operations. 

Unfavorable economic conditions may continue to 
impact demand for certain of our products and services. 
For example, decreases in employment have caused and 
could continue to cause lower enrollment in our employer 
group plans, lower enrollment in our non-employer 
individual plans and a higher number of employees opting 
out of our employer group plans. Unfavorable economic 
conditions have also caused and could continue to cause 
employers to stop offering certain health care coverage 
as an employee benefit or elect to offer this coverage on 
a voluntary, employee-funded basis as a means to reduce 
their operating costs. In addition, unfavorable economic 
conditions could continue to adversely impact our employer 
group renewal prospects and our ability to increase 
premiums and could result in cancellation of products 
and services by our customers. All of these could lead to a 
decrease in our membership levels and premium and fee 
revenues and could materially and adversely affect our 
results of operations, financial position and cash flows. 

During a prolonged unfavorable economic environment, 
state and federal budgets could be materially and adversely 
affected, resulting in reduced reimbursements or payments 
in our federal and state government health care coverage 
programs, including Medicare, Medicaid and CHIP. A 
reduction in state Medicaid reimbursement rates could 

22

UNITEDHEALTH GROUP

be implemented retrospectively to payments already 
negotiated and/or received from the government and could
materially and adversely affect our revenues, results of 
operations, financial position and cash flows. In addition,
the state and federal budgetary pressures could cause the 
government to impose new or a higher level of taxes or 
assessments for our commercial programs, such as premium 
taxes on insurance companies and health maintenance 
organizations and surcharges or fees on select fee-for-
service and capitated medical claims, and could materially 
and adversely affect our results of operations, financial 
position and cash flows. 

In addition, a prolonged unfavorable economic

environment could adversely impact the financial position 
of hospitals and other care providers, which could 
materially and adversely affect our contracted rates with 
these parties and increase our medical costs or materially 
and adversely affect their ability to purchase our service 
offerings. Further, unfavorable economic conditions could
adversely impact the customers of our Optum businesses, 
including health plans, HMOs, hospitals, care providers, 
employers and others, which could, in turn, materially and 
adversely affect Optum’s financial results.

Our investment portfolio may suffer losses, which could 
materially and adversely affect our results of operations, 
financial position and cash flows. 

Market fluctuations could impair our profitability and 

capital position. Volatility in interest rates affects our 
interest income and the market value of our investments 
in debt securities of varying maturities, which comprise 
the vast majority of the fair value of our investments as 
of December 31, 2011. Relatively low interest rates on 
investments, such as those experienced during recent years, 
have adversely impacted our investment income, and a 
prolonged low interest rate environment could further 
adversely affect our investment income. In addition, a 
delay in payment of principal and/or interest by issuers, or 
defaults by issuers (primarily from investments in corporate 
and municipal bonds), could reduce our net investment
income and we may be required to write down the value
of our investments, which would materially and adversely 
affect our profitability and shareholders’ equity. 

We also allocate a small proportion of our portfolio 

to equity investments, which are subject to greater 
volatility than fixed income investments. General economic 
conditions, stock market conditions, and many other factors 
beyond our control can materially and adversely affect 
the value of our equity investments and may result in 
investment losses. 

There can be no assurance that our investments will 

produce total positive returns or that we will not sell 
investments at prices that are less than their carrying 
values. Changes in the value of our investment assets, 
as a result of interest rate fluctuations, changes in issuer 
financial conditions, illiquidity or otherwise, could have
an adverse effect on our shareholders’ equity. In addition, 
if it became necessary for us to liquidate our investment 
portfolio on an accelerated basis, it could have a material 

adverse effect on our results of operations and the capital 
position of regulated subsidiaries. 

If the value of our intangible assets is materially impaired, 
our results of operations, shareholders’ equity and debt
ratings could be materially and adversely affected.

Goodwill and other intangible assets were $26.8 billion as
of December 31, 2011, representing 39% of our total assets. 
We periodically evaluate our goodwill and other intangible
assets to determine whether all or a portion of their 
carrying values may be impaired, in which case a charge 
to earnings may be necessary. For example, the manner 
in or the extent to which the Health Reform Legislation is 
implemented may impact our ability to maintain the value 
of our goodwill and other intangible assets in our business.
Similarly, the value of our goodwill may be materially and 
adversely impacted if businesses that we acquire perform 
in a manner that is inconsistent with our assumptions. 
In addition, from time to time we divest businesses, 
and any such divestiture could result in significant asset 
impairment and disposition charges, including those 
related to goodwill and other intangible assets. Any future 
evaluations requiring an impairment of our goodwill and
other intangible assets could materially and adversely affect 
our results of operations and shareholders’ equity in the 
period in which the impairment occurs. A material decrease 
in shareholders’ equity could, in turn, adversely impact our 
debt ratings or potentially impact our compliance with 
existing debt covenants. 

Large-scale medical emergencies may result in significant 
medical costs and may have a material adverse effect on 
our results of operations, financial position and cash flows.

Large-scale medical emergencies can take many 

forms and can cause widespread illness and death. Such 
emergencies could materially and adversely affect the 
U.S. economy in general and the health care industry 
specifically. For example, in the event of a natural disaster, 
bioterrorism attack, pandemic or other extreme events, we 
could face, among other things, significant medical costs 
and increased use of health care services. Any such disaster 
or similar event could have a material adverse effect on our 
results of operations, financial position and cash flows. 

If we fail to properly maintain the integrity or availability 
of our data or to strategically implement new or upgrade 
or consolidate existing information systems, or if our 
technology products do not operate as intended, our
business could be materially and adversely affected. 
Our ability to adequately price our products and 

services, to provide effective service to our customers in 
an efficient and uninterrupted fashion, and to accurately 
report our results of operations depends on the integrity 
of the data in our information systems. As a result of 
technology initiatives and recently enacted regulations, 
changes in our system platforms and integration of 
new business acquisitions, we have been consolidating
and integrating the number of systems we operate and 
have upgraded and expanded our information systems
capabilities. Our information systems require an ongoing 

commitment of significant resources to maintain, protect 
and enhance existing systems and develop new systems 
to keep pace with continuing changes in information 
processing technology, evolving systems and regulatory 
standards, emerging cybersecurity risks and threats, and 
changing customer patterns. If the information we rely 
upon to run our businesses was found to be inaccurate 
or unreliable or if we fail to maintain or protect our 
information systems and data integrity effectively, we 
could lose existing customers, have difficulty attracting 
new customers, have problems in determining medical 
cost estimates and establishing appropriate pricing, have 
difficulty preventing, detecting and controlling fraud, 
have disputes with customers, physicians and other health 
care professionals, have regulatory sanctions or penalties 
imposed, have increases in operating expenses or suffer 
other adverse consequences. There can be no assurance 
that our process of consolidating the number of systems we 
operate, upgrading and expanding our information systems 
capabilities, protecting our systems against cybersecurity 
risks and threats, enhancing our systems and developing 
new systems to keep pace with continuing changes in 
information processing technology will be successful or 
that additional systems issues will not arise in the future. 
Failure to protect, consolidate and integrate our systems 
successfully could result in higher than expected costs and 
diversion of management’s time and energy, which could 
materially and adversely affect our results of operations, 
financial position and cash flows. 

Certain of our businesses sell and install hardware 
and software products, and these products may contain 
unexpected design defects or may encounter unexpected 
complications during installation or when used with other 
technologies utilized by the customer. Connectivity among 
competing technologies is becoming increasingly important 
in the health care industry. A failure of our technology 
products to operate as intended and in a seamless fashion 
with other products could materially and adversely affect 
our results of operations, financial position and cash flows. 
In addition, an uncertain and rapidly evolving federal, 
state, international and industry legislative and regulatory 
framework related to the health information technology 
market may make it difficult to achieve and maintain 
compliance and could materially and adversely affect the 
configuration of our information systems and platforms, 
and our ability to compete in this market.

If we are not able to protect our proprietary rights to our 
databases and related products, our ability to market our 
knowledge and information-related businesses could be 
hindered and our results of operations, financial position 
and cash flows could be materially and adversely affected. 

We rely on our agreements with customers, 

confidentiality agreements with employees, and our 
trademarks, trade secrets, copyrights and patents to 
protect our proprietary rights. These legal protections 
and precautions may not prevent misappropriation of 
our proprietary information. In addition, substantial 
litigation regarding intellectual property rights exists in the 

2011 FORM 10-K

23

software industry, and we expect software products to be 
increasingly subject to third-party infringement claims as 
the number of products and competitors in this industry 
segment grows. Such litigation and misappropriation of our 
proprietary information could hinder our ability to market 
and sell products and services and our results of operations, 
financial position and cash flows could be materially and 
adversely affected.

Our ability to obtain funds from some of our subsidiaries 
is restricted and if we are unable to obtain sufficient funds 
from our subsidiaries to fund our obligations, our results of 
operations and financial position could be materially and 
adversely affected. 

Because we operate as a holding company, we are 
dependent upon dividends and administrative expense 
reimbursements from some of our subsidiaries to fund 
our obligations. Many of these subsidiaries are regulated 
by states’ departments of insurance. We are also required 
by law or regulation to maintain specific prescribed 
minimum amounts of capital in these subsidiaries. The 
levels of capitalization required depend primarily upon the 
volume of premium revenues generated by the applicable 
subsidiary. A significant increase in premium volume will 
require additional capitalization from us. In most states, 
we are required to seek prior approval by these state 
regulatory authorities before we transfer money or pay 
dividends from these subsidiaries that exceed specified 
amounts. An inability of our regulated subsidiaries to 
pay dividends to their parent companies in the desired 
amounts or at the time of our choosing could adversely 
affect our ability to reinvest in our business through capital 
expenditures or business acquisitions, as well as our ability 
to maintain our corporate quarterly dividend payment 
cycle, repurchase shares of our common stock and repay 
our debt. If we are unable to obtain sufficient funds from 
our subsidiaries to fund our obligations, our results of 
operations and financial position could be materially and 
adversely affected.

Any failure by us to manage and complete acquisitions and 
other significant strategic transactions successfully could 
materially and adversely affect our business, prospects, 
results of operations, financial position and cash flows. 

As part of our business strategy, we frequently engage 

in discussions with third parties regarding possible 
investments, acquisitions, divestitures, strategic alliances, 
joint ventures, and outsourcing transactions and often 
enter into agreements relating to such transactions. If 
we fail to identify and complete successfully transactions 
that further our strategic objectives, we may be required 
to expend resources to develop products and technology 
internally, we may be at a competitive disadvantage or we 
may be adversely affected by negative market perceptions, 
any of which may have a material adverse effect on our 
results of operations, financial position or cash flows. For 
acquisitions, success is also dependent upon efficiently 
integrating the acquired business into our existing 
operations. We are required to integrate these businesses

DIVIDEND POLICY 
In May 2011, our Board of Directors increased our cash 
dividend to shareholders to an annual dividend rate of
$0.65 per share, paid quarterly. Since June 2010, we had 
paid a quarterly dividend of $0.125 per share. Declaration 
and payment of future quarterly dividends is at the 
discretion of the Board and may be adjusted as business 
needs or market conditions change.

into our internal control environment, which may present 
challenges that are different than those presented by 
organic growth and that may be difficult to manage. 
If we are unable to successfully integrate and grow 
these acquisitions and to realize contemplated revenue 
synergies and cost savings, our business, prospects, results 
of operations, financial position and cash flows could be
materially and adversely affected. 

Downgrades in our credit ratings, should they occur, may 
adversely affect our business, financial condition and
results of operations. 

Claims paying ability, financial strength, and credit 

ratings by nationally recognized statistical rating 
organizations are important factors in establishing the 
competitive position of insurance companies. Ratings 
information is broadly disseminated and generally used 
throughout the industry. We believe our claims paying
ability and financial strength ratings are important factors 
in marketing our products to certain of our customers. Our 
credit ratings impact both the cost and availability of future 
borrowings. Each of the credit rating agencies reviews its 
ratings periodically and there can be no assurance that 
current credit ratings will be maintained in the future. Our 
ratings reflect each credit rating agency’s opinion of our 
financial strength, operating performance and ability to 
meet our debt obligations or obligations to policyholders.
Downgrades in our credit ratings, should they occur, may 
adversely affect our results of operations, financial position 
and cash flows.

Properties

To support our business operations in the United States and
other countries, as of December 31, 2011, we owned and/
or leased real properties totaling approximately 16 million
square feet, owning approximately 1 million aggregate 
square feet of space and leasing the remainder, primarily in 
the United States. Our leases expire at various dates through 
September 2028. Our various reporting segments use these
facilities for their respective business purposes, and we
believe these current facilities are suitable for their respective 
uses and are adequate for our anticipated future needs.

(a) In November 1997, our Board of Directors adopted a share repurchase program, which the Board evaluates periodically.
In May 2011, the Board renewed our share repurchase program with an authorization to repurchase up to 110 million 
shares of our common stock in open market purchases or other types of transactions (including prepaid or structured 
repurchase programs). There is no established expiration date for the program. As of December 31, 2011, we had Board 
authorization to purchase up to an additional 65 million shares of our common stock.

(b) Shares repurchased in December were purchased under a prepaid share repurchase program based on volume weighted 

average share prices for the fourth quarter.

PERFORMANCE GRAPHS 
The following two performance graphs compare our 
total return to shareholders with the returns of indexes 
of other specified companies and the S&P 500 Index. 
The first graph compares the cumulative five-year total 
return to shareholders on our common stock relative to 
the cumulative total returns of the S&P 500 index and a 
customized peer group of certain Fortune 50 companies 
(the “Fortune 50 Group”), for the five-year period ended 
December 31, 2011. The second graph compares our 
cumulative total return to shareholders with the S&P 500 
Index and an index of a group of peer companies selected 

0

by us for the five-year period ended December 31, 2011. We 
are not included in either the Fortune 50 Group index in the 
first graph or the peer group index in the second graph. In
calculating the cumulative total shareholder return of the 
indexes, the shareholder returns of the Fortune 50 Group 
companies in the first graph and the peer group companies 
in the second graph are weighted according to the stock
market capitalizations of the companies at January 1 of each 
year. The comparisons assume the investment of $100 on 
December 31, 2006 in our common stock and in each index,
and that dividends were reinvested when paid.

EXECUTIVE OVERVIEW 

GENERAL
UnitedHealth Group is a diversified health and well-being
company, whose mission is to help people live healthier 
lives and help make health care work better. Through 
our diversified family of businesses, we leverage core 
competencies in advanced, enabling technology; health care 
data, information and intelligence; and care management 
and coordination to help meet the demands of the health 
system. These core competencies are deployed within our 
two distinct, but strategically aligned, business platforms: 
health benefits operating under UnitedHealthcare and 
health services operating under Optum.  

UnitedHealthcare serves the health benefits needs of 
individuals across life’s stages through three businesses. 
UnitedHealthcare Employer & Individual serves individual 
consumers and employers. The unique health needs 
of seniors are served by UnitedHealthcare Medicare & 
Retirement. UnitedHealthcare Community & State serves 
the public health marketplace, offering states innovative 
Medicaid solutions.

UNITEDHEALTH GROUP

Optum serves health system participants including 
consumers, physicians, hospitals, governments, insurers, 
distributors and pharmaceutical companies, through its 
OptumHealth, OptumInsight and OptumRx businesses.

Our medical care ratio, calculated as medical costs as a 
percentage of premium revenues, reflects the combination 
of pricing, rebates, benefit designs, consumer health care 
utilization and comprehensive care facilitation efforts. 

REVENUES
Our revenues are primarily comprised of premiums derived
from risk-based health insurance arrangements in which 
the premium is typically at a fixed rate per individual served 
for a one-year period, and we assume the economic risk 
of funding our customers’ health care benefits and related 
administrative costs. Effective in 2011, commercial health 
plans with medical loss ratios on fully insured products, 
as calculated under the definitions in the Health Reform 
Legislation and implementing regulations, that fall below 
certain targets (85% for large employer groups, 80% for 
small employer groups and 80% for individuals, subject to 
state-specific exceptions) are required to rebate ratable 
portions of their premiums annually. As a result, our 
quarterly premium revenue may be reduced by a pro rata 
estimate of our full-year premium rebate payable under the 
Health Reform Legislation. Any required rebate payments 
for the current year are made in the third quarter of the 
subsequent year. We also generate revenues from fee-based 
services performed for customers that self-insure the health 
care costs of their employees and employees’ dependants. 
For both risk-based and fee-based health care benefit 
arrangements, we provide coordination and facilitation 
of medical services; transaction processing; health care 
professional services; and access to contracted networks of 
physicians, hospitals and other health care professionals. We 
also generate service revenues from our Optum businesses. 
Product revenues are mainly comprised of products sold 
by our pharmacy benefit management business. We derive 
investment income primarily from interest earned on our 
investments in debt securities; investment income also 
includes gains or losses when investment securities are sold, 
or other-than-temporarily impaired.

OPERATING COSTS
Medical Costs. Our operating results depend in large part 
on our ability to effectively estimate, price for and manage 
our medical costs through underwriting criteria, product 
design, negotiation of favorable care provider contracts 
and care coordination programs. Controlling medical costs 
requires a comprehensive and integrated approach to 
organize and advance the full range of interrelationships 
among patients/consumers, health professionals, hospitals, 
pharmaceutical/technology manufacturers and other
key stakeholders.

Medical costs include estimates of our obligations 
for medical care services rendered on behalf of insured 
consumers for which we have not yet received or processed 
claims, and our estimates for physician, hospital and 
other medical cost disputes. In every reporting period, our 
operating results include the effects of more completely 
developed medical costs payable estimates associated with 
previously reported periods.

Operating Costs. Operating costs are primarily comprised 
of costs related to employee compensation and benefits, 
agent and broker commissions, premium taxes and 
assessments, professional fees, advertising and occupancy 
costs. We seek to improve our operating cost ratio, 
calculated as operating costs as a percentage of total 
revenues, for an equivalent mix of business. However, 
changes in business mix, such as increases in the size of our 
health services businesses may impact our operating costs 
and operating cost ratio.

CASH FLOWS
We generate cash primarily from premiums, service and 
product revenues and investment income, as well as 
proceeds from the sale or maturity of our investments. 
Our primary uses of cash are for payments of medical 
claims and operating costs, payments on debt, purchases 
of investments, acquisitions, dividends to shareholders and 
common stock repurchases. For more information on our 
cash flows, see “Liquidity” below.

BUSINESS TRENDS
Our businesses participate in the U.S. health economy, 
which comprises approximately 18% of U.S. gross domestic 
product and has grown consistently for many years. We 
expect overall spending on health care in the U.S. to 
continue to grow in the future, due to inflation, medical 
technology and pharmaceutical advancement, regulatory 
requirements, demographic trends in the U.S. population 
and national interest in health and well-being. The rate
of market growth may be affected by a variety of factors, 
including macro-economic conditions and enacted
health care reforms, which could also impact our results 
of operations.  

In 2012, we expect increasing unit costs to continue 
to be the primary cost driver of medical cost trends and 
we project steadily increasing medical system utilization 
over the course of the year. We also expect an increase 
in prescription drug costs. We will continue to work to 
manage medical cost trends through care management 
programs, affordable network relationships, pay-for-
performance reimbursement programs for care providers, 
and targeted clinical management programs and 
initiatives focused on improving quality and affordability. 
Additionally, employers are continuing to select products 
with benefit designs that shift more of the costs to the 
employee. This cost shifting continues to mitigate increases 
in medical cost trends.

Our businesses focus on affordability, consumer 
empowerment, wellness and prevention, payment 
innovations, and enhanced distribution to better serve our
customer and consumer needs and demands. These business
objectives are consistent with the goals of health care 
reform. We expect that the portion of our costs that is tied 
to incentive contracts that reward providers for outcome-

based results and improved cost efficiencies will continue 
to increase. Care providers are facing market pressures to 
change from fee-for-service models to new delivery models 
focused on the holistic health of the consumer, integrated 
care across care providers and pay-for-performance 
payment structures. This is creating the need for health 
management services that can coordinate care around 
the primary care physician and for investment in new 
clinical and administrative information and management 
systems. The impact of such changes on our results of 
operations is uncertain but, we expect them to moderate 
the rate at which medical costs increase. This trend also 
provides growth opportunities for our OptumHealth and 
OptumInsight businesses. 

We attempt to price our products consistent with 
anticipated underlying medical trends, while balancing 
growth, margins, competitive dynamics and premium 
rebates at the local market level. We seek to sustain a 
stable medical care ratio for an equivalent mix of business. 
However, changes in business mix, such as expanding 
participation in comparatively higher medical care ratio 
government-sponsored public sector programs and Health 
Reform Legislation may impact our premiums, medical 
costs and medical care ratio. In 2012, we continue to expect 
reimbursements to be under pressure through government 
payment rates and continued market competition in 
commercial products.

REGULATORY TRENDS AND UNCERTAINTIES
In the first quarter of 2010, the Health Reform Legislation 
was signed into law. The Health Reform Legislation expands 
access to coverage and modifies aspects of the commercial 
insurance market, the Medicaid and Medicare programs, 
CHIP and other aspects of the health care system. HHS, the 
DOL, the IRS and the Treasury Department have issued or 
proposed regulations on a number of aspects of Health 
Reform Legislation, but final rules and interim guidance 
on other key aspects of the legislation, all of which have a 
variety of effective dates, remain pending.

The Health Reform Legislation and the related federal 
and state regulations will impact how we do business and 
could restrict growth and restrict premium rate increases in 
certain products and market segments, increase our medical 
and administrative costs, or expose us to an increased 
risk of liability, any or all of which could have a material 
adverse effect on us.

We also anticipate that the Health Reform Legislation 
will further increase attention on the need for health care 
cost containment and improvements in quality, with a 
focus on prevention, wellness and disease management. 
We believe demand for many of our service offerings, such 
as consulting services, data management, information 
technology and related infrastructure construction, disease 
management, and population-based health and wellness 
programs will continue to grow.

Following is a listing of some of the key provisions of 
the Health Reform Legislation and other regulatory items 
along with management’s view of the related trends and 
uncertainties that may cause reported financial information 

2011 FORM 10-K

29

to not be indicative of future operating performance or of 
future financial condition.

Premium Rebates
Effective in 2011, commercial health plans with medical 
loss ratios on fully insured products that fall below 
certain targets are required to rebate ratable portions 
of their premiums annually. The potential for and size of 
the rebates are measured by state, by group size and by 
licensed subsidiary.

In the aggregate, the rebate regulations cap the level of 

margin that can be attained.

The disaggregation of insurance pools into smaller pools 
will likely decrease the predictability of results for any given 
pool and could lead to variation over time in the estimates 
of rebates owed.

Other market participants could implement changes to 
their business practices in response to the Health Reform 
Legislation, which could positively or negatively impact our 
growth and market share. Insurers could elect to change 
pricing, modify product features or benefits, adjust their 
mix of business or even exit segments of the market. They 
could also seek to adjust their operating costs by making 
changes to their distribution arrangements or decreasing 
spending on non-medical product features and services. We 
have made changes to reduce our product distribution costs 
in the individual market in response to the Health Reform 
Legislation, including reducing producer commissions, 
and are implementing changes to distribution in the large 
group insured market segment. These changes could impact 
future growth in these products. 

Commercial Rate Increase Review
The Health Reform Legislation also requires HHS to 
maintain an annual review of “unreasonable” increases in 
premium rates for commercial health plans. HHS established 
a review threshold of annual premium rate increases 
generally at or above 10% (with state-specific thresholds to 
be applicable commencing September 2012), and clarified 
that the HHS review will not supersede existing state review 
and approval processes. The regulations further require 
commercial health plans to provide to the states and HHS 
extensive information supporting any rate increase of 
10% (or applicable state threshold) or more. Under the 
regulations, the HHS rate review process would apply only 
to health plans in the individual and small group markets.

The Federal government is also encouraging states 
to intensify their reviews of requests for rate increases
by affected commercial health plans (including large 
group plans) and providing funding to assist in those 
state-level reviews. Since August 2010, HHS has allocated 
approximately $250 million for grants to states to enable 
the states to conduct more robust reviews of requests 
for premium increases. Many states have applied for and 
received grants, and state regulators have signaled their 
intent to more closely scrutinize premium rates.

Premium rate review legislation (ranging from new 
or enhanced rate filing requirements to prior approval 
requirements) has been introduced or passed in more than 

30

UNITEDHEALTH GROUP

half of the states in 2011. As a result, we have begun to 
experience greater regulatory challenges to appropriate 
premium rate increases in several states, including 
California, New York and Rhode Island. Depending on the
level of scrutiny by the states, there is a broad range of 
potential business impacts. For example, it may become 
more difficult to price our commercial risk business 
consistent with expected underlying cost trends, leading to 
the risk of operating margin compression.

Medicare Advantage Rates
As part of the Health Reform Legislation, Medicare 
Advantage risk adjusted benchmarks, which ultimately 
drive our CMS payments, were reduced by 1.6% in 2011 
from 2010 levels. Beginning in 2012, additional cuts 
to Medicare Advantage benchmarks have taken effect 
(benchmarks will ultimately range from 95% of Medicare 
fee-for-service rates in high cost areas to 115% in low 
cost areas), with changes being phased-in over two to six
years, depending on the level of benchmark reduction in a
county. These changes could result in reduced enrollment
or reimbursement or payment levels.

We expect the 2012 rates will be outpaced by underlying 
medical trends, placing continued importance on effective 
medical management and ongoing improvements in 
administrative costs. There are a number of annual 
adjustments we can make to our operations, which may 
partially offset any impact from these rate reductions. 
For example, we can seek to intensify our medical and 
operating cost management, adjust members’ benefits and 
decide on a county-by-county basis in which geographies to
participate.

Additionally, achieving high quality scores from CMS 

for improving upon certain clinical and operational
performance standards will impact future quality bonuses 
that may offset these anticipated rate reductions. We 
also may be able to mitigate the effects of reduced 
funding on margins by increasing enrollment due to the
increases in the number of people eligible for Medicare 
in coming years. Longer term, market wide decreases in 
the availability or relative quality of Medicare Advantage 
products may increase demand for other senior health 
benefits products such as our Medicare Part D and Medicare 
Supplement insurance offerings.

It is also anticipated that CMS will release the final 
Medicare Advantage Risk Adjustment Data Validation 
(RADV) audit methodology in 2012. RADV audits are 
intended to validate that the risk-adjusted payments 
Medicare Advantage plans receive are supported by 
medical record data. Depending upon the final RADV
methodology released by CMS, recoveries from RADV 
audits may result in additional rate pressure.

Budget Control Act’s Medicare Sequestration
Congress passed the Budget Control Act of 2011, which,
following the failure of the Joint Select Committee 
on Deficit Reduction to cut the federal deficit by $1.2 
trillion, triggers automatic across-the-board budget 
cuts (sequestration), including Medicare spending cuts

averaging 2% of total program costs for nine years, starting 
in 2013. Medicare payments exempted from sequestration 
include:

(cid:116) (cid:49)(cid:66)(cid:90)(cid:78)(cid:70)(cid:79)(cid:85)(cid:84)(cid:1)(cid:85)(cid:80)(cid:1)(cid:84)(cid:85)(cid:66)(cid:85)(cid:70)(cid:84)(cid:1)(cid:71)(cid:80)(cid:83)(cid:1)(cid:68)(cid:80)(cid:87)(cid:70)(cid:83)(cid:66)(cid:72)(cid:70)(cid:1)(cid:80)(cid:71)(cid:1)(cid:46)(cid:70)(cid:69)(cid:74)(cid:68)(cid:66)(cid:83)(cid:70)(cid:1)(cid:68)(cid:80)(cid:84)(cid:85)(cid:14)

sharing for certain low-income Medicare beneficiaries.
The Office of Management and Budget is responsible for 

determining, calculating and implementing cuts. We are 
exploring strategies to mitigate any impact that may result 
from the cuts beginning in 2013.

Insurance Industry Fee
The Health Reform Legislation includes an annual insurance
industry assessment ($8 billion levied on the insurance 
industry in 2014 with increasing annual
amounts thereafter). The annual fee will be allocated
based on the ratio of an entity’s net premiums written 
during the preceding calendar year to the total health 
insurance for any U.S. health risk that is written during
the preceding calendar year, subject to certain exceptions 
and uncertainties.

Our effective income tax rate will increase significantly in 

2014 due to the non-deductibility of these fees. 

Premium increases will be necessary to offset the 

impact of these and other provisions. Premium increases 
are generally subject to state regulatory approval and 
potentially to federal review. Other market participants 
could increase premiums at different levels which could 
impact our market share positively or negatively.

State-based Exchanges and Coverage Expansion
Effective in 2014, exchanges are required to be established 
for individuals and small employers as well as certain CHIP 
eligibles. The exchanges will be state-based. If a state 
fails to establish an exchange by the required deadline, 
exchanges may be administered through a federal/state 
partnership or by the federal government.

Among other things, the Health Reform Legislation 

eliminates pre-existing condition exclusions and annual and
lifetime maximum limits and restricts the extent to which 
policies can be rescinded. The Health Reform Legislation
also provides for expanded Medicaid coverage effective
in January 2014. The Health Reform Legislation includes
an MOE provision that requires states to maintain their
eligibility rules for people covered by Medicaid, until the
Secretary of HHS determines that an insurance exchange is
operational in a given state. The MOE provision is intended
to prevent states from reducing eligibility standards and
determination procedures as a way to remove adults above
133% of the federal poverty level from Medicaid before
implementation of expanded Medicaid coverage effective
in January 2014. However, states with, or projecting, a
budget deficit may apply for an exception to the MOE 
provision. Additionally, individual states may accelerate their
procurement of Medicaid managed care services in 2012 and
2013 for sizeable groups of Medicaid program beneficiaries
in order to even their administrative workloads in advance
of Medicaid market expansion taking place in 2014.  

The Congressional Budget Office has estimated that up 

to 34 million additional individuals may eventually gain 
insurance coverage if the Health Reform Legislation is 
implemented broadly in its current form. This represents 
an opportunity for us to increase membership. However, 
serving these individuals may generate different profit 
margins than our existing business due to various factors, 
including the health status of the newly insured individuals.
We expect existing participants in Medicare and Medicaid 

and new enrollees in state-based exchanges to transition 
between products and programs, offering us opportunities 
to design products and services that enable us to compete 
for new business across business segments on an ongoing 
basis. An acceleration of Medicaid managed care services 
could increase near-term business growth opportunities for

UnitedHealthcare Community & State. However, if states 
are successful in obtaining MOE waivers and allow certain 
Medicaid programs to expire, we could experience reduced 
Medicaid enrollment. 

Court Proceedings
Court proceedings related to the Health Reform 
Legislation continue to evolve. These court proceedings, 
and the potential for Congressional action to impede 
implementation, create additional uncertainties with 
respect to the law. For additional information regarding 
the Health Reform Legislation, see Item 1, “Business - 
Government Regulation” and Item 1A, “Risk Factors.”

2011 RESULTS OF OPERATIONS  
COMPARED TO 2010 RESULTS

CONSOLIDATED FINANCIAL RESULTS
Revenues
The increases in revenues for the year ended December 31, 
2011 were driven by strong organic growth in the number
of individuals served in our UnitedHealthcare businesses, 
commercial premium rate increases reflecting underlying 
medical cost trends and revenue growth across all 
Optum businesses.

Medical Costs
Medical costs for the year ended December 31, 2011 
increased due to risk-based membership growth in our 
commercial and public and senior markets businesses 
and continued increases in the cost per service paid for 
health system use, and a modest increase in health system 
utilization, mainly in outpatient and physician office 
settings. Unit cost increases represented the majority of 
the increases in our medical cost trend, with the largest 
contributor being price increases to hospitals.

For each period, our operating results include the effects 

of revisions in medical cost estimates related to prior 
periods. Changes in medical cost estimates related to prior 
periods, resulting from more complete claim information 
identified in the current period, are included in total 
medical costs reported for the current period. For 2011 and 

2010 there was $720 million and $800 million, respectively, 
of net favorable medical cost development related to prior 
fiscal years. The favorable development in both periods 
was primarily driven by continued improvements in claims 
submission timeliness, which resulted in higher completion 
factors and lower than expected health system utilization 
levels. The favorable development in 2010 also benefited 
from a reduction in reserves needed for disputed claims 
from care providers; and favorable resolution of certain 
state-based assessments. 

Operating Costs
The increase in our operating costs for the year ended 
December 31, 2011 was due to business growth, including
an increased mix of Optum and UnitedHealthcare fee-
based and service revenues, which have higher operating
costs, and increased spending related to reform readiness 
and compliance. These factors were partially offset by 
overall operating cost management and the increase in 
2010 operating costs due to the goodwill impairment and
charges for a business line disposition of certain i3-branded 
clinical trial service businesses. See Note 6 of Notes to the 
Consolidated Financial Statements for further detail on the 
goodwill impairment.

Income Tax Rate
The effective income tax rate for the year ended December 
31, 2011 decreased compared to the prior year due to 
favorable resolution of various historical tax matters in the 
current year as well as a higher effective income tax rate 
in 2010, due to the cumulative implementation of certain 
changes under the Health Reform Legislation.

REPORTABLE SEGMENTS
Our two business platforms, UnitedHealthcare and Optum, 
are comprised of four reportable segments:

(cid:116)(cid:1)(cid:1)(cid:54)(cid:79)(cid:74)(cid:85)(cid:70)(cid:69)(cid:41)(cid:70)(cid:66)(cid:77)(cid:85)(cid:73)(cid:68)(cid:66)(cid:83)(cid:70)(cid:13)(cid:1)(cid:88)(cid:73)(cid:74)(cid:68)(cid:73)(cid:1)(cid:74)(cid:79)(cid:68)(cid:77)(cid:86)(cid:69)(cid:70)(cid:84)(cid:1)(cid:54)(cid:79)(cid:74)(cid:85)(cid:70)(cid:69)(cid:41)(cid:70)(cid:66)(cid:77)(cid:85)(cid:73)(cid:68)(cid:66)(cid:83)(cid:70)(cid:1)

See Note 13 of Notes to the Consolidated Financial 

Statements for a description of the types and services from 
which each of our reportable segments derives its revenues.
Transactions between reportable segments principally 

consist of sales of pharmacy benefit products and 
services to UnitedHealthcare customers by OptumRx, 
certain product offerings and clinical services sold to 
UnitedHealthcare by OptumHealth, and health information 
and technology solutions, consulting and other services sold
to UnitedHealthcare by OptumInsight. These transactions 
are recorded at management’s estimate of fair value. 
Intersegment transactions are eliminated in consolidation.

On January 1, 2011, we realigned certain of our businesses to respond to changes in the markets we serve. Prior period 
segment financial information has been recast to conform to the 2011 presentation. See Note 2 of Notes to Consolidated 
Financial Statements for more information on our business realignment. The following table presents reportable segment

UNITEDHEALTH GROUP

UnitedHealthcare’s revenue growth for the year ended 
December 31, 2011 was due to growth in the number of 
individuals served across our businesses and commercial 
premium rate increases reflecting expected underlying 
medical cost trends.

UnitedHealthcare’s earnings from operations for the year 
ended December 31, 2011 increased compared to the prior 
year as revenue growth and improvements in the operating 
cost ratio more than offset increased compliance costs and 
an increase to the medical care ratio, which was primarily 
due to the initiation of premium rebate obligations in 2011,
and lower favorable reserve development levels. 

In our Medicare Part D stand-alone business, we estimate 
that we entered January 2012 down approximately 625,000 
people, primarily as a result of the loss of approximately 
470,000 of our auto-assigned low-income subsidy Medicare
Part D beneficiaries in a number of regions being 
automatically reassigned to other plans as part of the 
annual bid process managed by CMS. We believe that we
will grow from this level throughout the course of the year 
in the open retail market.

In February 2012, we added 117,000 Medicare Advantage

members from the acquisition of XLHealth Corporation.

Optum. Total revenue for these businesses increased 
in 2011 due to business growth and acquisitions at 
OptumHealth and OptumInsight and growth in customers 
served through pharmaceutical benefit management 
programs at OptumRx.

Optum’s operating margin for the year ended December 

31, 2011 was down compared to 2010. The decrease was 
due to changes in business mix within Optum’s businesses 
and realignment of certain internal business arrangements.

The results by segment were as follows:

OptumHealth
Increased revenues at OptumHealth for the year ended 
December 31, 2011 were primarily due to expansions in 
service offerings through acquisitions in clinical services, 
as well as growth in consumer and population health
management offerings.  

Earnings from operations for the year ended December 

31, 2011 and operating margin decreased compared 
to 2010. The decreases reflect the impact from internal 
business and service arrangement realignments and the mix 
effect of growth and expansion in newer businesses such as 
clinical services.

OptumInsight
Increased revenues at OptumInsight for the year ended 
December 31, 2011 were due to the impact of organic 
growth and the full-year impact of 2010 acquisitions, which 
were partially offset by the divestiture of the clinical trials 
services business in June 2011.

The increases in earnings from operations and operating 

margins for the year ended December 31, 2011 reflect an 
increased mix of higher margin services in 2011 as well as 
the effect on 2010 earnings from operations and operating 
margin of the goodwill impairment and charges for a 
business line disposition of certain i3-branded clinical

trial service businesses. See Note 6 of Notes to the 
Consolidated Financial Statements for further detail on
the goodwill impairment.

OptumRx
The increase in OptumRx revenues for the year ended 
December 31, 2011 was due to increased prescription 
volumes, primarily due to growth in customers served 
through Medicare Part D prescription drug plans by 
our UnitedHealthcare Medicare & Retirement business, 
and a favorable mix of higher revenue specialty drug 
prescriptions. Intersegment revenues eliminated in 
consolidation were $16.7 billion and $14.4 billion for the
years ended December 31, 2011 and 2010, respectively.
OptumRx earnings from operations and operating 
margins for 2011 decreased as the mix of lower margin 
specialty pharmaceuticals and Medicaid business and 
investments to support growth initiatives including the 
in-sourcing of our commercial pharmacy benefit programs 
more than offset the earnings contribution from higher 
revenues and greater use of generic medications.

We will consolidate and manage the majority of our 
commercial pharmacy benefit programs internally when 
our contract with Medco Health Solutions, Inc. expires at 
the end of 2012. The investments in our infrastructure 
and to expand our capacity will likely cause a decrease in
earnings from operations and operating margin as in 2012, 
OptumRx expects to absorb approximately $115 million of 
the $150 million consolidated in-sourcing related operating
costs. As a result of this transition, OptumRx expects to add 
12 million members on a staged basis in 2013. See Item 1A, 
“Risk Factors” for a discussion of certain risks associated 
with the transition of our commercial pharmacy benefit 
programs to OptumRx.

2010 RESULTS OF OPERATIONS  
COMPARED TO 2009 RESULTS 

CONSOLIDATED FINANCIAL RESULTS

Revenues
The increases in revenues for 2010 were primarily due to 
strong organic growth in risk-based benefit offerings in 
our public and senior markets businesses and commercial 
premium rate increases reflecting underlying medical 
cost trends. Growth in customers served by our health 
services businesses, particularly through pharmaceutical 
benefit management programs, increased revenues from 
public sector behavioral health programs and increased 
sales of health care technology software and services also 
contributed to our revenue growth.

Medical Costs and Medical Care Ratio
Medical costs for 2010 increased primarily due to growth 
in our public and senior markets risk-based businesses and 
medical cost inflation, which were partially offset by net 
favorable development of prior period medical costs. 

For 2010 and 2009, there was $800 million and $310 

million, respectively, of net favorable medical cost 
development related to prior fiscal years.

The medical care ratio decreased due to a moderation 
in overall demand for medical services, successful clinical 
engagement and management and the increase in prior 
period favorable development discussed previously.

Operating Costs
Operating costs for 2010 increased due to acquired and 
organic growth in health services businesses, which are 
generally more operating cost intensive than our benefits 
businesses, goodwill impairment and charges for a business 
line disposition at OptumInsight, which is discussed in more 
detail below, an increase in staffing and selling expenses 
primarily due to the change in the Medicare Advantage 
annual enrollment period, costs related to increased 
employee headcount and compensation, increased 
advertising costs, and the absorption of new business 
development and start-up costs.

Income Tax Rate
The increase in our effective income tax rate for 2010 as 
compared to 2009 resulted from a benefit in the 2009 
tax rate from the resolution of various historical state 
income tax matters and an increase in the 2010 rate 
related to limitations on the future deductibility of certain 
compensation due to the Health Reform Legislation.

REPORTABLE SEGMENTS

UnitedHealthcare
The revenue growth in UnitedHealthcare for 2010 was 
primarily due to growth in the number of individuals served 
by our public and senior markets businesses and commercial 
premium rate increases reflecting underlying medical cost 
trends, partially offset by Medicare Advantage premium 
rate decreases.

UnitedHealthcare earnings from operations and 

operating margins for 2010 increased over the prior year 
due to factors that increased revenues described above, 
continued cost management disciplines on behalf of 
our commercial and governmental customers, a general 
moderation in year-over-year growth in demand for 
medical services and the effect of increased net favorable 
development in prior period medical costs.

OptumHealth
Increased revenues in OptumHealth for 2010 were primarily 
driven by new business development in large scale public 
sector programs and increased sales of benefits and services 
to external employer markets. 

The operating margin for 2010 decreased due to growth 

in lower margin public sector business, new market 
development and startup costs and costs related to the 
implementation of the federal Mental Health Parity & 
Addiction Equity Act of 2008.

OptumInsight
Increased revenues in OptumInsight for 2010 were primarily 
due to the impact of acquisitions and growth in health 
information technology offerings and services focused on 
cost and data management and regulatory compliance. 

The decrease in operating margin for 2010 was primarily 

2011 FORM 10-K

35

due to a goodwill impairment and charges for a business 
line disposition of certain i3-branded clinical trial service 
businesses. In addition, increases in the mix of lower margin 
business, continued margin pressure in the pharmaceutical 
services business and continued investments in new growth 
areas also contributed to the decrease in operating margin 
in 2010. See Note 6 of Notes to the Consolidated Financial 
Statements for further detail on the goodwill impairment.

OptumRx
The increased OptumRx revenues for 2010 were primarily 
due to growth in customers served through Medicare 
Part D prescription drug plans by our UnitedHealthcare 
Medicare & Retirement business and higher prescription 
volumes. Intersegment revenues eliminated in 
consolidation were $14.4 billion and $12.5 billion for 2010 
and 2009, respectively. 

OptumRx operating margin for 2010 decreased due 
to changes in performance-based pricing contracts with 
Medicare Part D plan sponsors, which were partially offset 
by prescription volume growth, increased usage of mail 
service and generic drugs by consumers and effective 
operating cost management.

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- 
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 non-cash expenses. The risk of decreased 
operating cash flow from a decline in earnings is partially 
mitigated by the diversity of our businesses, geographies 
and customers; our disciplined underwriting and pricing 
processes for our risk-based businesses; and continued 
productivity improvements that lower our operating costs.

Our regulated subsidiaries generate significant cash 
flows from operations. A majority of the assets held by 
our regulated subsidiaries are in the form of cash, cash 
equivalents and investments. After considering expected 
cash flows from operating activities, we generally invest cash 
of regulated subsidiaries that exceeds our expected short-
term obligations in longer term, liquid, investment-grade, 
debt securities to improve our overall investment return. We 
make these investments pursuant to our Board of Directors’ 
approved investment policy, which focuses on preservation 
of capital through risk tolerances around liquidity, credit 
quality, issuer limits, asset class diversification, income and 
duration. The policy emphasizes investment grade bonds
with durations that are short to intermediate term in 
nature. The policy also generally governs return objectives, 
regulatory limitations and tax implications.

UNITEDHEALTH GROUP

Our regulated subsidiaries are subject to financial 
regulations and standards in their respective states of 
domicile. Most of these regulations and standards conform 
to those established by the NAIC. These standards, among 
other things, require these subsidiaries to maintain 
specified levels of statutory capital, as defined by each 
state, and restrict the timing and amount of dividends 
and other distributions that may be paid to their parent 
companies. Except in the case of extraordinary dividends, 
these standards generally permit dividends to be paid from 
statutory unassigned surplus of the regulated subsidiary 
and are limited based on the regulated subsidiary’s level 
of statutory net income and statutory capital and surplus. 
These dividends are referred to as “ordinary dividends” and 
generally can be paid without prior regulatory approval.
If the dividend, together with other dividends paid within
the preceding twelve months, exceeds a specified statutory 
limit or is paid from sources other than earned surplus, the 
entire dividend is generally considered an “extraordinary 
dividend” and must receive prior regulatory approval.

In 2011, based on the 2010 statutory net income and 
statutory capital and surplus levels, the maximum amount 

Summary of our Major Sources and Uses of Cash

of ordinary dividends which could be paid was $3.4 billion.
For the year ended December 31, 2011, our regulated 
subsidiaries paid their parent companies dividends of $4.5 
billion, including $1.1 billion of extraordinary dividends.
For the year ended December 31, 2010, our regulated 
subsidiaries paid their parent companies dividends of $3.2 
billion, including $686 million of extraordinary dividends.
Our non-regulated businesses also generate cash flows 

from operations 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 drawings under our committed credit 
facility, 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, or return capital to 
our shareholders through shareholder dividends and/or
repurchases of our common stock, depending on market 
conditions.

2011 Cash Flows Compared to 2010 Cash Flows
Cash flows from operating activities increased $695 million, 
or 11%, from 2010. The increase was primarily driven by 
growth in net earnings and changes in various working 
capital accounts, which were partially offset by a reduction 
in unearned revenues due to the early receipt of certain 
2011 state Medicaid premium payments in 2010, which 
increased 2010 cash from operating activities. We anticipate 
lower year over year cash flows from operations in 2012, 
which will include payments in the third quarter for 2011 
premium rebate obligations. 

Cash flows used for investing activities decreased 
$1.2 billion, or 22%, primarily due to relatively lower 

investments in acquisitions in 2011 and a decrease in net 
purchases of investments. We anticipate an increase in cash 
paid for acquisitions in 2012 as compared to 2011.

Cash flows used for financing activities increased 
$879 million, or 55%, primarily due to increased share 
repurchases and cash dividends in 2011, partially offset by 
an increase in net borrowings.

2010 Cash Flows Compared to 2009 Cash Flows 
Cash flows from operating activities increased $648 
million, or 12%, for 2010. Factors that increased cash flows 
from operating activities were growth in net earnings, 
an acceleration of certain 2011 premium payments, and 
an increase in pharmacy rebate collections, which were 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
partially offset by a mandated acceleration in the claim 
payment cycle associated with the Medicare Part D program 
and payment for the settlement of the American Medical 
Association class action litigation related to reimbursement 
for out-of-network medical services. 

Cash flows used for investing activities increased $4.4 
billion, primarily due to acquisitions completed in 2010, 
decreases in sales of investments due to a more stable 
market environment and the use of operating cash to 
purchase investments. 

Cash flows used for financing activities decreased $664 

million, or 29%, primarily due to proceeds from the 
issuance of commercial paper and long-term debt, partially 
offset by increases in common stock repurchases and cash 
dividends paid on our common stock. 

FINANCIAL CONDITION
As of December 31, 2011, our cash, cash equivalent and 
available-for-sale investment balances of $28.0 billion 
included $9.4 billion of cash and cash equivalents (of which 
$1.6 billion was held by non-regulated entities), $18.0 
billion of debt securities and $544 million of investments 
in equity securities and venture capital funds. 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. The use of different market 
assumptions or valuation methodologies, primarily used in 
valuing our Level 3 securities (those securities priced using 
significant unobservable inputs), may have an effect on the 
estimated fair value amounts of our investments. Due to 
the subjective nature of these assumptions, the estimates 
may not be indicative of the actual exit price if we had sold 
the investment at the measurement date. We had $417 
million of Level 3 securities as of December 31, 2011. Other 
sources of liquidity, primarily from operating cash flows 
and our commercial paper program, which is supported by 
our $3.0 billion bank credit facility, reduce the need to sell 
investments during adverse market conditions. See Note 
4 of Notes to the Consolidated Financial Statements for 
further detail of our fair value measurements.

Our cash equivalent and investment portfolio has a 
weighted-average duration of 2.1 years and a weighted-
average credit rating of “AA” as of December 31, 2011. 
Included in the debt securities balance are $2.4 billion of 
state and municipal obligations that are guaranteed by a 
number of third parties. Due to the high underlying credit 
ratings of the issuers, the weighted-average credit rating 
of these securities both with and without the guarantee 
is “AA” as of December 31, 2011. We do not have any 
significant exposure to any single guarantor (neither 
indirect through the guarantees, nor direct through 

2011 FORM 10-K

37

investment in the guarantor). When multiple credit ratings 
are available for an individual security, the average of 
the available ratings is used to determine the weighted-
average credit rating.

CAPITAL RESOURCES AND USES OF LIQUIDITY
In addition to cash flow from operations and cash and cash 
equivalent balances available for general corporate use, our 
capital resources and uses of liquidity are as follows:

Commercial Paper.rr  We maintain a commercial paper 
borrowing program, which facilitates the private placement 
of unsecured debt through third-party broker-dealers. The 
commercial paper program is supported by the $3.0 billion 
bank credit facility described below. As of December 31, 
2011, we had no commercial paper outstanding.

Bank Credit Facility. In December 2011, we amended 
and renewed our five-year revolving bank credit facility 
with 21 banks, which will mature in December 2016. The 
amendment included increasing the borrowing capacity 
to $3.0 billion. This facility supports our commercial paper 
program and is available for general corporate purposes. 
There were no amounts outstanding under this facility as 
of December 31, 2011. The interest rate on borrowings 
is variable based on term and amount and is calculated 
based on the LIBOR plus a credit spread based on our 
senior unsecured credit ratings. As of December 31, 2011, 
the annual interest rate on this facility, had it been drawn, 
would have ranged from 1.2% to 1.7%.

Our bank credit facility contains various covenants, 
including requiring us to maintain a debt to debt-plus-
equity ratio below 50%. Our debt to debt-plus-equity 
ratio, calculated as the sum of debt divided by the sum of 
debt and shareholders’ equity, was 29.1% and 30.1% as of 
December 31, 2011 and December 31, 2010, respectively. 
We were in compliance with our debt covenants as of 
December 31, 2011.

Long-term debt. Periodically, we access capital markets 
and issue long-term debt for general corporate purposes 
and the funds may be used, for example, to meet our 
working capital requirements, to refinance debt, to finance 
acquisitions, for share repurchases or for other general 
corporate purposes.

In November 2011, we issued $1.5 billion in senior 
unsecured notes. The issuance included $400 million of 
1.9% fixed-rate notes due November 2016, $500 million of 
3.4% fixed-rate notes due November 2021 and $600 million 
of 4.6% notes due November 2041.

In February 2011, we issued $750 million in senior 
unsecured notes. The issuance included $400 million of 
4.7% fixed-rate notes due February 2021 and $350 million 
of 6.0% fixed-rate notes due February 2041.

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. For 
example, a significant downgrade in our credit ratings 
or conditions in the capital markets may increase the 
cost of borrowing for us or limit our access to capital. We 
have adopted strategies and actions toward maintaining 
financial flexibility to mitigate the impact of such factors on 
our ability to raise capital.

Share Repurchases. Under our Board of Directors’ 
authorization, we maintain a common share repurchase 
program. Repurchases may be made from time to time 
in open market purchases or other types of transactions 
(including prepaid or structured repurchase programs), 
subject to certain preset parameters established by 
our Board. In May 2011, our Board renewed our share
repurchase program with an authorization to repurchase 
up to 110 million shares of our common stock. During the 
year ended December 31, 2011, we repurchased 65 million 
shares at an average price of approximately $46 per share 

and an aggregate cost of $3.0 billion. As of December 31, 
2011, we had Board authorization to purchase up to an
additional 65 million shares of our common stock. 

Dividends. In May 2011, our Board of Directors increased 
our cash dividend to shareholders to an annual dividend
rate of $0.65 per share, paid quarterly. Since June 2010, 
we had paid a quarterly dividend of $0.125 per share.
Declaration and payment of future quarterly dividends is at 
the discretion of the Board and may be adjusted as business 
needs or market conditions change. On February 8, 2012, 
our Board of Directors approved a quarterly dividend of 
$0.1625 per share.

(a) Includes interest coupon payments and maturities at par or put values. Coupon payments have been calculated using 

stated rates from the debt agreements and assuming amounts are outstanding through their contractual term. See Note 
8 of Notes to the Consolidated Financial Statements for more detail. 

(b) Includes fixed or minimum commitments under existing purchase obligations for goods and services, including

agreements that are cancelable with the payment of an early termination penalty. Excludes agreements that are 
cancelable without penalty and excludes liabilities to the extent recorded in our Consolidated Balance Sheets as of 
December 31, 2011. 

(c) Future policy benefits represent account balances that accrue to the benefit of the policyholders, excluding surrender 

charges, for universal life and investment annuity products and for long-duration health policies sold to individuals for 
which some of the premium received in the earlier years is intended to pay benefits to be incurred in future years. See 
Note 2 of Notes to the Consolidated Financial Statements for more detail. 

(d) As the timing of future settlements is uncertain, the long-term portion has been classified as “Thereafter.”
(e) Includes obligations associated with contingent consideration and other payments related to business acquisitions,

certain employee benefit programs, charitable contributions related to the PacifiCare acquisition and various other 
long-term liabilities. Due to uncertainty regarding payment timing, obligations for employee benefit programs, 
charitable contributions and other liabilities have been classified as “Thereafter.”

We do not have other significant contractual obligations 
or commitments that require cash resources; however, 
we continually evaluate opportunities to expand our 
operations. This includes internal development of new 
products, programs and technology applications, and may 
include acquisitions.

OFF-BALANCE SHEET ARRANGEMENTS 

As of December 31, 2011, we were not involved in off-
balance sheet arrangements which have or are reasonably 
likely to have a material effect on our financial condition, 
results of operations or liquidity. 

RECENTLY ISSUED ACCOUNTING STANDARDS

In July 2011, the Financial Accounting Standards Board 
(FASB) issued Accounting Standards Update (ASU) No. 2011-
06, “Other Expenses (Topic 720): Fees Paid to the Federal 
Government by Health Insurers a consensus of the FASB 
Emerging Issues Task Force” (ASU 2011-06). This update 
addresses the recognition and classification of an entity’s 
share of the annual health insurance industry assessment 
(the fee) mandated by Health Reform Legislation. The fee 
will be levied on health insurers for each calendar year 
beginning on or after January 1, 2014 and is not deductible 
for income tax purposes. The fee will be allocated to 
health insurers based on the ratio of an entity’s net health 
premiums written during the preceding calendar year to 
the total health insurance for any U.S. health risk that is 
written during the preceding calendar year. In accordance 
with the amendments in ASU 2011-06, our liability for the 
fee will be estimated and recorded in full once we provide 
qualifying health insurance in the applicable calendar year 
in which the fee is payable (first applicable in 2014) with 
a corresponding deferred cost that will be amortized to 
expense using a straight-line method of allocation unless 
another method better allocates the fee over the calendar 
year that it is payable. 

We have determined that there have been no other 

recently issued accounting standards that will have a 
material impact on our Consolidated Financial Statements.

CRITICAL ACCOUNTING ESTIMATES

Critical accounting estimates are those estimates that 
require management to make challenging, subjective or 
complex judgments, often because they must estimate the 
effects of matters that are inherently uncertain and may 
change in subsequent periods. Critical accounting estimates 
involve judgments and uncertainties that are sufficiently 
sensitive and may result in materially different results under 
different assumptions and conditions. 

Medical Costs 
Each reporting period, we estimate our obligations for 
medical care services that have been rendered on behalf 
of insured consumers but for which claims have either 
not yet been received or processed and for liabilities for 
physician, hospital and other medical cost disputes. We 

2011 FORM 10-K

39

develop estimates for medical care services incurred but 
not reported using an actuarial process that is consistently 
applied, centrally controlled and automated. The actuarial 
models consider factors such as time from date of service 
to claim receipt, claim processing backlogs, seasonal 
variances in medical care consumption, health care 
professional contract rate changes, medical care utilization 
and other medical cost trends, membership volume and 
demographics, benefit plan changes, and business mix 
changes related to products, customers and geography. 
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. Substantially all claims 
related to medical care services are known and settled 
within nine to twelve months from the date of service. We 
estimate liabilities for physician, hospital and other medical 
cost disputes based upon an analysis of potential outcomes, 
assuming a combination of litigation and settlement actions. 

Each period, we re-examine previously established 
medical costs payable estimates based on actual claim 
submissions and other changes in facts and circumstances. 
As more complete claim 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 change is identified. In every 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 2011, 2010 
and 2009, included net favorable medical cost development 
related to prior periods of $720 million, $800 million and 
$310 million, respectively. This development represented 
approximately 8%, 9% and 4% of the medical claims 
payable balance as of December 31, 2010, 2009 and 2008, 
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, we actuarially calculate completion factors using 
an analysis of claim adjudication patterns over the most 
recent 36-month period. A completion factor is an actuarial 
estimate, based upon historical experience and analysis of 
current trends, of the percentage of incurred claims during 
a given period that have been adjudicated by us at the date 
of estimation. For months prior to the most recent three 
months, we apply the completion factors to actual claims 
adjudicated-to-date to estimate the expected amount of 
ultimate incurred claims for those months. For the most 
recent three months, we estimate claim costs incurred 
primarily 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 

40

UNITEDHEALTH GROUP

completion factors. This approach is consistently applied 
from period to period. 

Medical Costs PMPM Trend
Increase (Decrease) in Factors

Completion Factors. Completion factors are the most 
significant factors we use in developing our medical costs 
payable estimates for older periods, generally periods 
prior to the most recent three months. The completion 
factor includes judgments in relation to claim submissions 
such as the time from date of service to claim receipt, 
claim inventory levels and claim processing backlogs as 
well as other factors. If actual claims submission rates 
from providers (which can be influenced by a number of
factors including provider mix and electronic versus manual 
submissions) or our claim processing patterns are different 
than estimated, our reserves 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, 2011:

Medical cost PMPM trend factors. Medical cost PMPM 
trend factors are the most significant factors we use in 
developing our medical costs payable estimates for the 
most recent three 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 by reviewing a broad set of 
health care utilization indicators including, but not limited
to, pharmacy utilization trends, inpatient hospital census 
data and incidence data from the National Centers for 
Disease Control. We also consider macroeconomic variables 
such as gross-domestic product growth, employment and 
disposable income. A large number of factors can cause the 
medical cost trend to vary from our estimates including: 
our ability and practices to manage medical costs, changes 
in level and mix of services utilized, mix of benefits offered 
including the impact of co-pays and deductibles, changes in
medical practices, catastrophes, epidemics, the introduction 
of new or costly treatments and technology, new mandated 
benefits or other regulatory changes, insured population 
characteristics and seasonal changes in the level of health 
care use. 

The following table illustrates the sensitivity of these 
factors and the estimated potential impact on our medical 
costs payable estimates for the most recent three months as 
of December 31, 2011:

The analyses above include outcomes that are considered 

reasonably likely based on our historical experience 
estimating liabilities for incurred but not reported benefit 
claims.

Our estimate of medical costs payable represents 
management’s best estimate of our liability for unpaid 
medical costs as of December 31, 2011, developed using 
consistently applied actuarial methods. Management 
believes the amount of medical costs payable is reasonable 
and adequate to cover our liability for unpaid claims as 
of December 31, 2011; however, actual claim payments 
may differ from established estimates as discussed above. 
Assuming a hypothetical 1% difference between our 
December 31, 2011 estimates of medical costs payable and 
actual medical costs payable, excluding AARP Medicare 
Supplement Insurance and any potential offsetting impact 
from premium rebates, 2011 net earnings would have 
increased or decreased by $56 million and diluted net 
earnings per common share would have increased or 
decreased by $0.05 per share. 

The current national health care cost inflation rate 
significantly exceeds the general inflation rate. We use 
various strategies to lessen the effects of health care cost 
inflation. These include coordinating care with physicians
and other health care professionals and rate discounts 
from physicians and other health care professionals. 
Through contracts with physicians and other health care 
professionals, we emphasize preventive health care, 
appropriate use of health care services consistent with 
clinical performance standards, education and closing gaps 
in care. 

We believe our strategies to mitigate the impact of 
health care cost inflation on our operating results have 
been and will continue to be successful. However, other
factors including competitive pressures, new health care 
and pharmaceutical product introductions, demands 
from physicians and other health care professionals and 
consumers, major epidemics, and applicable regulations 
may affect our ability to control the impact of health care 
cost inflation. Because of the narrow operating margins 
of our risk-based products, changes in medical cost trends 
that were not anticipated in establishing premium rates can 
create significant changes in our financial results. 

REVENUES
Revenues are principally derived from health care insurance 
premiums. We recognize premium revenues in the 
period eligible individuals are entitled to receive health 
care services. Customers are typically billed monthly at a 

contracted rate per eligible person multiplied by the total 
number of people eligible to receive services, as recorded in 
our records. Effective in 2011, premium revenue subject to 
the premium rebates of the Health Reform Legislation are 
recognized based on the estimated premium earned net of 
the projected rebates over the period of the contract, when 
that amount can be reasonably estimated. The estimated 
premium is revised each period to reflect current experience. 
The most significant factors in estimating these rebates are 
financial performance within each aggregation set, including 
medical claim experience and effective tax rates, as well as 
changes in business mix and regulatory requirements. We 
revise estimates of revenue adjustments each period and 
record changes in the period they become known.
Our Medicare Advantage and Part D premium 

revenues are subject to periodic adjustment under CMS’ 
risk adjustment payment methodology. The CMS risk 
adjustment model provides higher per member payments 
for enrollees diagnosed with certain conditions and lower 
payments for enrollees who are healthier. We and other 
health care plans collect, capture, and submit available 
diagnosis data to CMS within prescribed deadlines. CMS 
uses submitted diagnosis codes, demographic information, 
and special statuses to determine the risk score for most 
Medicare Advantage beneficiaries. CMS also retroactively 
adjusts risk scores during the year based on additional data.  
We estimate risk adjustment revenues based upon the data 
submitted and expected to be submitted to CMS. As a result 
of the variability of factors that determine such estimations, 
the actual amount of CMS’ retroactive payments could be 
materially more or less than our estimates. This may result
in favorable or unfavorable adjustments to our Medicare 
premium revenue and, accordingly, our profitability. 
Medicare Advantage risk adjustment data for certain of our 
plans is subject to audit by regulators. See Note 12 of Notes 
to the Consolidated Financial Statements in this Form 10-K 
for additional information regarding these audits.

GOODWILL AND INTANGIBLE ASSETS
Goodwill. Goodwill represents the amount of the purchase 
price in excess of the fair values assigned to the underlying 
identifiable net assets of acquired businesses. Goodwill 
is not amortized, but is subject to an annual impairment 
test. Tests are performed more frequently if events occur
or circumstances change that would more likely than 
not reduce the fair value of the reporting unit below its 
carrying amount. 

To determine whether goodwill is impaired, we perform 

a multi-step impairment test. First, we can elect to 
perform a qualitative assessment of each reporting unit 
to determine whether facts and circumstances support a 
determination that their fair values are greater than their 
carrying values. If the qualitative analysis is not conclusive, 
or if we elect to proceed directly with quantitative testing, 
we will then measure the fair values of the reporting units 
and compare them to their aggregate carrying values, 
including goodwill. If the fair value is less than the carrying 
value of the reporting unit, then the implied value of 
goodwill would be calculated and compared to the carrying 

2011 FORM 10-K

41

amount of goodwill to determine whether goodwill is 
impaired.

We estimate the fair values of our reporting units using 

discounted cash flows, which include assumptions about 
a wide variety of internal and external factors. Significant 
assumptions used in the impairment analysis include 
financial projections of free cash flow (including significant 
assumptions about operations, capital requirements and 
income taxes), long-term growth rates for determining 
terminal value, and discount rates. For each reporting unit, 
comparative market multiples are used to corroborate the 
results of our discounted cash flow test. 

Forecasts and long-term growth rates used for our 
reporting units are consistent with, and use inputs from, 
our internal long-term business plan and strategy. Key 
assumptions used in these forecasts include:

(cid:116) Revenue trends. Key drivers for each reporting unit 
are determined and assessed. Significant factors 
include: membership growth, medical trends, and the 
impact and expectations of regulatory environments. 
Additional macro-economic assumptions around 
unemployment, GDP growth, interest rates, and 
inflation are also evaluated and incorporated.

(cid:116) Medical cost trends. See further discussion of medical 

costs trends within Medical Costs above. Similar factors 
are considered in estimating our long-term medical 
trends at the reporting unit level.

(cid:116) Operating productivity.yy  We forecast expected 

operating cost levels based on historical levels and 
expectations of future operating cost productivity 
initiatives.

(cid:116)(cid:1)(cid:1)Capital levels. The capital structure and requirements 

for each business is considered.

Although we believe that the financial projections used 

are reasonable and appropriate for all of our reporting 
units, due to the long-term nature of the forecasts there 
is significant uncertainty inherent in those projections. 
That uncertainty is increased by the impact of health care 
reforms as discussed in Item 1, “Business - Government 
Regulation”. For additional discussions regarding how the 
enactment or implementation of health care reforms and 
how other factors could affect our business and the related 
long-term forecasts, see Item 1A, “Risk Factors” in Part I 
and “Regulatory Trends and Uncertainties” above. 

Discount rates are determined for each reporting unit 

based on the implied risk inherent in their forecasts. 
This risk is evaluated using comparisons to market 
information such as peer company weighted average 
costs of capital and peer company stock prices in the form 
of revenue and earnings multiples. Beyond our selection 
of the most appropriate risk-free rates and equity risk 
premiums, our most significant estimates in the discount 
rate determinations involve our adjustments to the peer 
company weighted average costs of capital that reflect 
reporting unit-specific factors. Such adjustments include 
the addition of size premiums and company-specific risk 
premiums intended to compensate for apparent forecast 
risk. We have not made any adjustments to decrease a 

42

UNITEDHEALTH GROUP

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 in regards 
to the reporting units’ operations could cause these 
assumptions to change in the future.

We elected to bypass the optional qualitative reporting 

unit fair value assessment and completed our annual 
quantitative tests for goodwill impairment as of January 1, 
2012. All of our reporting units had fair values substantially 
in excess of their carrying values, thus we concluded that 
there was no need for any impairment of our goodwill 
balances as of December 31, 2011. 

Intangible assets. Finite-lived, separately-identifiable 
intangible assets are acquired in business combinations 
and are assets that represent future expected benefits but 
lack physical substance (e.g., membership lists, customer 
contracts, trademarks and technology). We do not have 
material holdings of indefinite-lived intangible assets. Our 
intangible assets are initially recorded at their fair values 
and are then amortized over their expected useful lives. 
Our most significant intangible assets are customer-related 
intangibles which represent 88% of our total intangible 
balance of $2.8 billion.

Customer-related intangible assets acquired in business 
combinations are typically valued using an income approach
based on discounted future cash flows attributable to 
customers that exist as of the date of acquisition. The most 
significant assumptions used in the valuation of customer-
related assets include: projected revenue and earnings 
growth, retention rate, perpetuity growth rate and discount 
rate. These initial valuations and the embedded assumptions 
contain uncertainty to the extent that those assumptions 
and estimates may ultimately differ from actual results 
(e.g., customer turnover may be higher or lower than the 
assumed retention rate suggested).

Our intangible assets are subject to impairment tests 
when events or circumstances indicate that a finite-lived 
intangible asset’s (or asset group’s) carrying value may 
exceed its estimated fair value. Consideration is given on 
a quarterly basis to a number of potential impairment 
indicators including: changes in the use of an intangible
asset, changes in legal or other business factors that could 
affect value, experienced or expected operating cash-
flow deterioration or losses, adverse changes in customer 
populations, adverse competitive or technological advances 
that could impact value, and other factors. Following the 
identification of any potential impairment indicators, we 
would calculate the estimated fair value of a finite-lived 
intangible asset using the undiscounted cash flows that 
are expected to result from the use of the asset or related 
group of assets. If the carrying value exceeds its estimated 
fair value, an impairment would be recorded. 

There were no material impairments of finite-lived 

intangible assets during 2011.

INVESTMENTS
As of December 31, 2011, we had investments with a 
carrying value of $18.7 billion, primarily held in marketable 
debt securities. Our investments are principally classified 
as available-for-sale and are recorded at fair value. We 
exclude gross unrealized gains and losses on available-for-
sale investments from earnings and report net unrealized 
gains or losses, net of income tax effects, as a separate 
component in shareholders’ equity. 

We continually monitor the difference between the cost 
and fair value of our investments. As of December 31, 2011, 
our investments had gross unrealized gains of $787 million 
and gross unrealized losses of $32 million. We evaluate 
investments for impairment considering factors including:

(cid:116) (cid:80)(cid:86)(cid:83)(cid:1)(cid:74)(cid:79)(cid:85)(cid:70)(cid:79)(cid:85)(cid:1)(cid:85)(cid:80)(cid:1)(cid:84)(cid:70)(cid:77)(cid:77)(cid:1)(cid:85)(cid:73)(cid:70)(cid:1)(cid:84)(cid:70)(cid:68)(cid:86)(cid:83)(cid:74)(cid:85)(cid:90)(cid:1)(cid:80)(cid:83)(cid:1)(cid:85)(cid:73)(cid:70)(cid:1)(cid:77)(cid:74)(cid:76)(cid:70)(cid:77)(cid:74)(cid:73)(cid:80)(cid:80)(cid:69)(cid:1)(cid:85)(cid:73)(cid:66)(cid:85)(cid:1)(cid:88)(cid:70)(cid:1)
will be required to sell the security before recovery of 
the entire amortized cost;

(cid:116) (cid:85)(cid:73)(cid:70)(cid:1)(cid:77)(cid:70)(cid:79)(cid:72)(cid:85)(cid:73)(cid:1)(cid:80)(cid:71)(cid:1)(cid:85)(cid:74)(cid:78)(cid:70)(cid:1)(cid:66)(cid:79)(cid:69)(cid:1)(cid:70)(cid:89)(cid:85)(cid:70)(cid:79)(cid:85)(cid:1)(cid:85)(cid:80)(cid:1)(cid:88)(cid:73)(cid:74)(cid:68)(cid:73)(cid:1)(cid:78)(cid:66)(cid:83)(cid:76)(cid:70)(cid:85)(cid:1)(cid:87)(cid:66)(cid:77)(cid:86)(cid:70)(cid:1)

has been less than cost; and

(cid:116) (cid:85)(cid:73)(cid:70)(cid:1)(cid:229)(cid:79)(cid:66)(cid:79)(cid:68)(cid:74)(cid:66)(cid:77)(cid:1)(cid:68)(cid:80)(cid:79)(cid:69)(cid:74)(cid:85)(cid:74)(cid:80)(cid:79)(cid:1)(cid:66)(cid:79)(cid:69)(cid:1)(cid:79)(cid:70)(cid:66)(cid:83)(cid:14)(cid:85)(cid:70)(cid:83)(cid:78)(cid:1)(cid:81)(cid:83)(cid:80)(cid:84)(cid:81)(cid:70)(cid:68)(cid:85)(cid:84)(cid:1)(cid:80)(cid:71)(cid:1)(cid:85)(cid:73)(cid:70)(cid:1)
issuer as well as specific events or circumstances that 
may influence the operations of the issuer.
For debt securities, if we intend to either sell or 

determine that we will be more likely than not be required 
to sell a debt security before recovery of the entire 
amortized cost basis or maturity of the debt security, we 
recognize the entire impairment in earnings. If we do not 
intend to sell the debt security and we determine that we 
will not be more likely than not be required to sell the 
debt security but we do not expect to recover the entire 
amortized cost basis, the impairment is bifurcated into the 
amount attributed to the credit loss, which is recognized 
in earnings, and all other causes, which are recognized in
other comprehensive income. 

For equity securities, we recognize impairments in other 

comprehensive income if we expect to hold the equity 
security until fair value increases to at least the equity 
security’s cost basis and we expect that increase in fair value 
to occur in a reasonably forecasted period. If we intend to 
sell the equity security or if we believe that recovery of fair 
value to cost will not occur in the near term, we recognize 
the impairment in through our income statement. 
Inherently, there is uncertainty included in the 
impairment assessment of investments. Our analysis 
includes significant judgments and estimates including: the 
fair value of the investment, the underlying credit quality 
of the issuers and the credit ratings of the issuer other 
forms of credit enhancements, the financial condition and 
near term prospects of the issuer, and general industry and 
sector economic conditions. 

Fair values. We perform an analysis around the fair values 
of the securities held including obtaining an understanding
of the pricing method and procedures over the valuation
of securities. Fair values of available-for-sale debt and 
equity securities are based on quoted market prices, 
where available. We obtain one price for each security 
primarily from a third-party pricing service (pricing service), 
which generally uses quoted or other observable inputs

for the determination of fair value. The pricing service 
normally derives the security prices through recently 
reported trades for identical or similar securities, making 
adjustments through the reporting date based upon 
available observable market information. For securities not 
actively traded, the pricing service may use quoted market 
prices of comparable instruments or discounted cash flow 
analyses, incorporating inputs that are currently observable 
in the markets for similar securities. Inputs that are often
used in the valuation methodologies include, but are not 
limited to, benchmark yields, credit spreads, default rates 
and prepayment speeds, and non-binding broker quotes. 
As we are responsible for the determination of fair value, 
we perform quarterly analyses on the prices received from 
the pricing service to determine whether the prices are 
reasonable estimates of fair value. Specifically, we compare:
(cid:116) (cid:85)(cid:73)(cid:70)(cid:1)(cid:81)(cid:83)(cid:74)(cid:68)(cid:70)(cid:84)(cid:1)(cid:83)(cid:70)(cid:68)(cid:70)(cid:74)(cid:87)(cid:70)(cid:69)(cid:1)(cid:71)(cid:83)(cid:80)(cid:78)(cid:1)(cid:85)(cid:73)(cid:70)(cid:1)(cid:81)(cid:83)(cid:74)(cid:68)(cid:74)(cid:79)(cid:72)(cid:1)(cid:84)(cid:70)(cid:83)(cid:87)(cid:74)(cid:68)(cid:70)(cid:1)(cid:85)(cid:80)(cid:1)(cid:81)(cid:83)(cid:74)(cid:68)(cid:70)(cid:84)(cid:1)

reported by a secondary pricing service, its custodian, 
its investment consultant and/or third-party investment 
advisors; and

(cid:116) (cid:68)(cid:73)(cid:66)(cid:79)(cid:72)(cid:70)(cid:84)(cid:1)(cid:74)(cid:79)(cid:1)(cid:85)(cid:73)(cid:70)(cid:1)(cid:83)(cid:70)(cid:81)(cid:80)(cid:83)(cid:85)(cid:70)(cid:69)(cid:1)(cid:78)(cid:66)(cid:83)(cid:76)(cid:70)(cid:85)(cid:1)(cid:87)(cid:66)(cid:77)(cid:86)(cid:70)(cid:84)(cid:1)(cid:66)(cid:79)(cid:69)(cid:1)(cid:83)(cid:70)(cid:85)(cid:86)(cid:83)(cid:79)(cid:84)(cid:1)(cid:85)(cid:80)(cid:1)
relevant market indices and our expectations to test 
the reasonableness of the reported prices.

Based on our internal price verification procedures and 
our review of the fair value methodology documentation 
provided by independent pricing service, we have not 
historically adjusted the prices obtained from the 
pricing service. 

Other-than-temporary impairment assessment. Individual
securities with fair values lower than costs are reviewed for 
impairment considering the factors above including: the 
length of time of impairment, credit standing, financial 
condition, near term-prospects and other factors specific to 
the issuer. Other factors included in the assessment include 
the type and nature of the securities and liquidity. Given 
the nature of our portfolio, primarily investment grade 
securities, the primary causes of historical impairments
were market related (e.g., interest rate fluctuations, etc) 
as opposed to credit related. We do not expect that trend 
to change in the near term. Generally, we do not assume 
that we will be required to sell a security because our large 
cash holdings reduce this risk. However, our intent to sell 
a security may change from period to period if facts and 
circumstances change.

We believe we will collect the principal and interest due 

on our debt securities with an amortized cost in excess 
of fair value. The unrealized losses at December 31, 2011 
and 2010 were primarily caused by market interest rate 
increases and not by unfavorable changes in the credit 
standing. We manage our investment portfolio to limit our 
exposure to any one issuer or market sector, and largely 
limit our investments to U.S. government and agency 
securities; state and municipal securities; mortgage-backed 
securities; and corporate debt obligations, substantially 
all of investment-grade quality. Securities downgraded 
below policy minimums after purchase will be disposed of 
in accordance with our investment policy. Total other-than-
temporary impairments during 2011, 2010 and 2009 were 

2011 FORM 10-K

43

$12 million, $23 million and $64 million, respectively. Our 
cash equivalent and investment portfolio has a weighted-
average duration of 2.1 years and a weighted-average credit 
rating of “AA” as of December 31, 2011. We have minimal 
securities collateralized by sub-prime or Alt-A securities, and 
a minimal amount of commercial mortgage loans in default. 

The judgments and estimates related to fair value and 
other-than-temporary impairment may ultimately prove to 
be inaccurate due to many factors including: circumstances 
may change over time, industry sector and market factors 
may differ from expectations and estimates or we may 
ultimately sell a security we previously intended to hold. 
Our assessment of the financial condition and near-term 
prospects of the issuer may ultimately prove to be inaccurate 
as time passes and new information becomes available 
including current facts and circumstances changing, or as 
unknown or estimated unlikely trends develop.

As discussed further in Item 7A “Quantitative and 

Qualitative Disclosures About Market Risk” a 1% increase 
in market interest rates has the effect of decreasing the fair
value of our investment portfolio by $622 million.

INCOME TAXES
Our provision for income taxes, deferred tax assets 
and liabilities, and uncertain tax positions reflect our 
assessment of estimated future taxes to be paid on items
in the consolidated financial statements. Deferred income 
taxes arise from temporary differences between financial
reporting and tax reporting bases of assets and liabilities, as 
well as net operating loss and tax credit carryforwards for 
tax purposes. 

We have established a valuation allowance against 

certain deferred tax assets based on the weight of available 
evidence (both positive and negative) for which it is more-
likely-than-not that some portion, or all, of the deferred tax 
asset will not be realized. After application of the valuation 
allowances, we anticipate that no limitations will apply 
with respect to utilization of any of the other net deferred 
income tax assets. We believe that our estimates for the 
valuation allowances against deferred tax assets and tax 
contingency reserves are appropriate based on current facts 
and circumstances. 

According to U.S. Generally Accepted Accounting 
Principles (GAAP), a tax benefit from an uncertain tax 
position may be recognized when it is more likely than 
not that the position will be sustained upon examination, 
including resolutions of any related appeals or litigation 
processes, based on the technical merits. 

We have established an estimated liability for federal, 

state and non-U.S. income tax exposures that arise and 
meet the criteria for accrual under U.S. GAAP. We prepare 
and file tax returns based on our interpretation of tax 
laws and regulations and record estimates based on these 
judgments and interpretations. In the normal course of 
business, our tax returns are subject to examination by 
various taxing authorities. Such examinations may result 
in future tax and interest assessments by these taxing 
authorities. Inherent uncertainties exist in estimates of tax 
contingencies due to changes in tax law resulting from 

44

UNITEDHEALTH GROUP

legislation, regulation and/or as concluded through the
various jurisdictions’ tax court systems. 

The significant assumptions and estimates described 

above are important contributors to our ultimate effective 
tax rate in each year. A hypothetical increase or decrease in 
our effective tax rate by 1% on our 2011 earnings before 
income taxes would have caused the provision for income 
taxes to change by $80 million. 

CONTINGENT LIABILITIES
Because of the nature of our businesses, we are routinely 
involved in various disputes, legal proceedings and
governmental audits and investigations. We record 
liabilities for our estimates of the probable costs resulting 
from these matters where appropriate. Our estimates 
are developed in consultation with outside legal counsel,
if appropriate, and are based upon an analysis of 
potential results, assuming a combination of litigation 
and settlement strategies and considering our insurance 
coverage, if any, for such matters. 

Estimates of probable costs resulting from legal and 
regulatory matters involving us are inherently difficult 
to predict, particularly where the matters: involve 
indeterminate claims for monetary damages or may involve 
fines, penalties or punitive damages; present novel legal 
theories or represent a shift in regulatory policy; involve 
a large number of claimants or regulatory bodies; are in 
the early stages of the proceedings; or could result in a 
change in business practices. Accordingly, in many cases, 
we are unable to estimate the losses or ranges of losses for 
those matters where there is a reasonable possibility or it is 
probable that a loss may be incurred. 

Given this inherent uncertainty, it is possible that 
future results of operations for any particular quarterly 
or annual period could be materially affected by changes
in our estimates or assumptions. We evaluate our related 
disclosures each reporting period, see Note 12 of Notes 
to the Consolidated Financial Statements for discussion 
of specific legal proceedings including an assessment of 
whether a reasonable estimate of the losses or range of loss 
could be determined. 

LEGAL MATTERS 

A description of our legal proceedings is included in Note
12 of Notes to the Consolidated Financial Statements and is 
incorporated by reference in this report.

CONCENTRATIONS OF CREDIT RISK

Investments in financial instruments such as marketable 
securities and accounts receivable may subject us to 
concentrations of credit risk. Our investments in marketable 
securities are managed under an investment policy 
authorized by our Board of Directors. This policy limits 
the amounts that may be invested in any one issuer and 
generally limits our investments to U.S. government 
and agency securities, state and municipal securities and 
corporate debt obligations that are investment grade. 
Concentrations of credit risk with respect to accounts 

receivable are limited due to the large number of employer 
groups and other customers that constitute our client 
base. As of December 31, 2011, we had an aggregate $1.9 
billion reinsurance receivable resulting from the sale of our 
Golden Rule Financial Corporation life and annuity business
in 2005. We regularly evaluate the financial condition of 
the reinsurer and only record the reinsurance receivable 
to the extent that the amounts are deemed probable of 
recovery. Currently, the reinsurer is rated by A.M. Best 
as “A+.” As of December 31, 2011, there were no other 
significant concentrations of credit risk.

ITEM 7A. Quantitative And Qualitative 
Disclosures About Market Risk

Our primary market risks are exposures to (a) changes 
in interest rates that impact our investment income and 
interest expense and the fair value of certain of our fixed-
rate investments and debt and (b) changes in equity prices 
that impact the value of our equity investments.

As of December 31, 2011, $9.4 billion of our investments
were classified as cash and cash equivalents on which interest
rates received vary with market interest rates, which may 
materially impact our investment income. Also, OptumHealth
Bank held $1.4 billion of deposit liabilities as of December
31, 2011 at interest rates that vary with market rates.

The fair value of certain of our fixed-rate investments and 

debt also varies with market interest rates. As of December 
31, 2011, $18.2 billion of our investments were fixed-rate 
debt securities and $11.6 billion of our debt was fixed-rate 
term debt. An increase in market interest rates decreases the 
market value of fixed-rate investments and fixed-rate debt. 
Conversely, a decrease in market interest rates increases the 
market value of fixed-rate investments and fixed-rate debt.

We manage exposure to market interest rates by 
diversifying investments across different fixed income 
market sectors and debt across maturities, as well as 
endeavoring to match our floating-rate assets and liabilities 
over time, either directly or periodically through the use of 
interest rate swap contracts. In the second half of 2011, we 
terminated all of our interest rate swap fair value hedges 
with a $5.4 billion notional amount in order to lock-in the
impact of low market floating interest rates and reduce 
the effective interest rate on hedged long-term debt. The 
gain of $132 million will be realized over the remaining 
life of the applicable hedged fixed-rate debt as a reduction 
to interest expense in the Consolidated Statements of 
Operations. Additional information on our interest rate 
swaps is included in Note 8 of Notes to the Consolidated 
Financial Statements. Since the interest rate swaps have 
been terminated, the fair value of our long-term debt is 
now more sensitive to hypothetical changes in interest 
rates as the change in the fair value of the debt is no 
longer offset by the swaps. Also as a result of the swaps’ 
termination, our exposure to hypothetical changes in 
market rates on our interest expense is less volatile.

The following tables summarize the impact of hypothetical changes in market interest rates across the entire yield curve 

by 1% or 2% as of December 31, 2011 and 2010 on our investment income and interest expense per annum, and the fair 
value of our investments and debt (in millions):

(a) Given the low absolute level of short-term market rates on our floating-rate assets and liabilities as of December 31, 

2011 and 2010, the assumed hypothetical change in interest rates does not reflect the full 1% point reduction in interest 
income or interest expense as the rate cannot fall below zero and thus the 2% point reduction is not meaningful.

(b) As of December 31, 2011, some of our investments had interest rates below 2% so the assumed hypothetical change in 

the fair value of investments does not reflect the full 2% point reduction.

As of December 31, 2011, we had $544 million of investments in equity securities and venture capital funds, a portion 
of which were invested in various public and non-public companies concentrated in the areas of health care delivery and 
related information technologies. Market conditions that affect the value of health care or technology stocks will impact 
the value of our equity investments.

UNITEDHEALTH GROUP

ITEM 8.

Financial Statements

REPORT OF INDEPENDENT REGISTERED PUBLIC
ACCOUNTING FIRM
To the Board of Directors and Shareholders of UnitedHealth 
Group Incorporated and Subsidiaries: 

We have audited the accompanying consolidated
balance sheets of UnitedHealth Group Incorporated 
and Subsidiaries (the “Company”) as of December 31, 
2011 and 2010, and the related consolidated statements 
of operations, stockholders’ equity and cash flows for 
each of the three years in the period ended December 
31, 2011. These consolidated financial statements are 
the responsibility of the Company’s management. Our 
responsibility is to express an opinion on these consolidated
financial statements based on our audits. 

We conducted our audits in accordance with the

standards of the Public Company Accounting Oversight 
Board (United States). Those standards require that we 
plan and perform the audit to obtain reasonable assurance 
about whether the consolidated financial statements are 
free of material misstatement. An audit includes examining, 
on a test basis, evidence supporting the amounts and 
disclosures in the consolidated financial statements. An 
audit also includes assessing the accounting principles used 
and significant estimates made by management, as well as 
evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for 
our opinion. 

In our opinion, such consolidated financial statements 
present fairly, in all material respects, the financial position 
of UnitedHealth Group Incorporated and Subsidiaries as 
of December 31, 2011 and 2010, and the results of their 
operations and their cash flows for each of the three years 
in the period ended December 31, 2011, in conformity with 
accounting principles generally accepted in the United
States of America. 

We have also audited, in accordance with the standards 
of the Public Company Accounting Oversight Board (United
States), the Company’s internal control over financial 
reporting as of December 31, 2011, based on the criteria 
established in Internal Control - Integrated Framework 
issued by the Committee of Sponsoring Organizations of 
the Treadway Commission and our report dated February 
8, 2012 expressed an unqualified opinion on the Company’s
internal control over financial reporting.

NOTES TO THE CONSOLIDATED  
FINANCIAL STATEMENTS

1.  DESCRIPTION OF BUSINESS
 UnitedHealth Group Incorporated (also referred to as 
“UnitedHealth Group” and “the Company”) is a diversified 
health and well-being company whose mission is to help 
people live healthier lives and make health care work 
better.

The Company helps individuals access quality care at an 
affordable cost; simplifying health care administration and 
delivery; strengthening the physician/patient relationship; 
promoting evidence-based care; and empowering 
physicians, health care professionals, consumers, employers 
and other participants in the health system with actionable 
data to make better, more informed decisions.  

Through the Company’s diversified family of businesses, 

it leverages core competencies in advanced, enabling 
technology; health care data, information and intelligence; 
and care management and coordination to help meet the 
demands of the health system. 

2. BASIS OF PRESENTATION, USE OF ESTIMATES AND

SIGNIFICANT ACCOUNTING POLICIES

The Company has prepared the Consolidated Financial 
Statements according to U.S. Generally Accepted 
Accounting Principles (GAAP) and has included the accounts 
of UnitedHealth Group and its subsidiaries. The Company 
has eliminated intercompany balances and transactions. 

yy

During the first quarter of 2011, the Company 
renamed its reportable segments to conform to the 
naming conventions of its market facing businesses. 
Consequently, the Health Benefits reportable segment is 
now UnitedHealthcare, and the health services businesses, 
OptumHealth, Ingenix, and Prescriptions Solutions, are now 
aligned under Optum as OptumHealth, OptumInsight, and 
OptumRx, respectively. On January 1, 2011, the Company 
realigned certain of its businesses to respond to changes 
in the markets it serves and the opportunities that are 
emerging as the health system evolves. For example, 
OptumHealth’s results of operations now include the 
Company’s clinical services assets, including Southwest 
Medical multi-specialty clinics in Nevada and Evercare 
nurse practitioners serving the frail and elderly, which had 
historically been reported in UnitedHealthcare Employer & 
Individual and UnitedHealthcare Medicare & Retirement, 
respectively. UnitedHealthcare Employer & Individual’s 
results of operations now include OptumHealth Specialty 
Benefits, including dental, vision, life and disability. The 
Company’s reportable segments remain the same and prior 
period segment financial information has been recast to 
conform to the 2011 presentation. See Note 13 of Notes 
to the Consolidated Financial Statements for segment 
financial information.

2011 FORM 10-K

51

Use of Estimates
These Consolidated Financial Statements include certain 
amounts based on the Company’s best estimates and 
judgments. The Company’s most significant estimates 
relate to medical costs payable and medical costs, premium 
rebates and risk-sharing provisions related to revenues, 
valuation and impairment analysis of goodwill and other 
intangible assets, other policy liabilities, other current 
receivables, valuation of investments, income taxes 
and contingent liabilities. These estimates require the 
application of complex assumptions and judgments, often 
because they involve matters that are inherently uncertain 
and will likely change in subsequent periods. The impact 
of any changes in estimates is included in earnings in the 
period in which the estimate is adjusted.

Revenues
Premium revenues are primarily derived from risk-based 
health insurance arrangements in which the premium is 
typically at a fixed rate per individual served for a one-
year period, and the Company assumes the economic 
risk of funding its customers’ health care and related 
administrative costs. Effective in 2011, commercial health 
plans with medical loss ratios on fully insured products, as 
calculated under the definitions in the Patient Protection 
and Affordable Care Act and its related reconciliation act 
(Health Reform Legislation) and implementing regulations, 
that fall below certain targets are required to rebate 
ratable portions of their premiums annually. The Company 
classifies its estimated rebates as an offset to Premium
Revenues in the Consolidated Statement of Operations. 
Premium revenues are recognized in the period in which 
eligible individuals are entitled to receive health care 
benefits. Health care premium payments received from its 
customers in advance of the service period are recorded as 
unearned revenues. The Company also records premium 
revenues from capitation arrangements at its collaborative 
care businesses.

The Centers for Medicare and Medicaid Services (CMS) 
deploys a risk adjustment model that 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 
indicates they have certain medical conditions. Under 
this risk adjustment methodology, CMS calculates the risk 
adjusted premium payment using diagnosis data from 
hospital inpatient, hospital outpatient and physician 
treatment settings. The Company and health care providers 
collect, capture, and submit the necessary and available 
diagnosis data to CMS within prescribed deadlines. The 
Company estimates risk adjustment revenues based upon 
the diagnosis data submitted and expected to be submitted 
to CMS. Risk adjustment data for certain of the Company’s 
plans is subject to audit by regulators. See Note 12 of Notes 
to the Consolidated Financial Statements for additional 
information regarding these audits. 

Service revenues consist primarily of fees derived from 
services performed for customers that self-insure the health 
care costs of their employees and employees’ dependants. 

52

UNITEDHEALTH GROUP

Under service fee contracts, the Company recognizes 
revenue in the period the related services are performed. 
The customers retain the risk of financing health care 
costs for their employees and employees’ dependants, 
and the Company administers the payment of customer 
funds to physicians and other health care professionals 
from customer-funded bank accounts. As the Company has 
neither the obligation for funding the health care costs, 
nor the primary responsibility for providing the medical 
care, the Company does not recognize premium revenue 
and medical costs for these contracts in its Consolidated 
Financial Statements. 

For both risk-based and fee-based customer 

arrangements, the Company provides coordination and
facilitation of medical services; transaction processing; 
customer, consumer and care professional services; and 
access to contracted networks of physicians, hospitals 
and other health care professionals. These services are 
performed throughout the contract period.

For the Company’s OptumRx pharmacy benefits 

management (PBM) business, revenues are derived from 
products sold through a contracted network of retail 
pharmacies, and from administrative services, including 
claims processing and formulary design and management. 
Product revenues include ingredient costs (net of rebates), 
a negotiated dispensing fee and customer co-payments 
for drugs dispensed through the Company’s mail-service 
pharmacy. In retail pharmacy transactions, revenues 
recognized always exclude the member’s applicable 
co-payment. Product revenues are recognized when the
prescriptions are dispensed through the retail network or 
received by consumers through the Company’s mail-service 
pharmacy. Service revenues are recognized when the 
prescription claim is adjudicated. The Company has entered 
into retail service contracts in which it is primarily obligated 
to pay its network pharmacy providers for benefits 
provided to their customers regardless if the Company 
is paid. The Company is also involved in establishing the
prices charged by retail pharmacies, determining which 
drugs will be included in formulary listings and selecting 
which retail pharmacies will be included in the network
offered to plan sponsors’ members. As a result, revenues 
are reported on a gross basis.

Medical Costs and Medical Costs Payable 
Medical costs and medical costs payable include estimates 
of the Company’s obligations for medical care services 
that have been rendered on behalf of insured consumers, 
but for which claims have either not yet been received 
or processed, and for liabilities for physician, hospital 
and other medical cost disputes. The Company develops 
estimates for medical costs incurred but not reported using 
an actuarial process that is consistently applied, centrally 
controlled and automated. The actuarial models consider 
factors such as time from date of service to claim receipt, 
claim processing backlogs, care provider contract rate 
changes, medical care consumption and other medical cost 
trends. The Company estimates liabilities for physician, 
hospital and other medical cost disputes based upon an

analysis of potential outcomes, assuming a combination 
of litigation and settlement strategies. Each period, the 
Company re-examines previously established medical costs 
payable estimates based on actual claim submissions and 
other changes in facts and circumstances. As the medical 
costs payable estimates recorded in prior periods develop, 
the Company adjusts the amount of the estimates and 
includes the changes in estimates in medical costs in the 
period in which the change is identified. Medical costs also
include the direct cost of patient care rendered through 
OptumHealth.

Cash, Cash Equivalents and Investments 
Cash and cash equivalents are highly liquid investments 
that have an original maturity of three months or less. 
The fair value of cash and cash equivalents approximates 
their carrying value because of the short maturity of the 
instruments.

The Company had checks outstanding in excess of
bank deposits at the related accounts of $1.5 billion as 
of December 31, 2011 and $1.3 billion as of December 
31, 2010, which were classified as Accounts Payable and 
Accrued Liabilities in the Consolidated Balance Sheets and
the change in this balance has been reflected as Checks 
Outstanding in Excess of Bank Deposits within financing 
activities in the Consolidated Statements of Cash Flows. The 
Company does not net checks outstanding with deposits in
other accounts.

Investments with maturities of less than one year 

are classified as short-term. Because of regulatory 
requirements, certain investments are included in long-term 
investments regardless of their maturity date. The Company 
classifies these investments as held-to-maturity and reports 
them at amortized cost. Substantially all other investments 
are classified as available-for-sale and reported at fair value 
based on quoted market prices, where available. 

The Company excludes unrealized gains and losses on
investments in available-for-sale securities from earnings 
and reports them, net of income tax effects, as a separate 
component of shareholders’ equity. To calculate realized 
gains and losses on the sale of investments, the Company uses 
the specific cost or amortized cost of each investment sold. 
The Company evaluates an investment for impairment by 
considering the length of time and extent to which market 
value has been less than cost or amortized cost, the financial 
condition and near-term prospects of the issuer as well 
as specific events or circumstances that may influence the 
operations of the issuer and the Company’s intent to sell the 
security or the likelihood that it will be required to sell the 
security before recovery of the entire amortized cost. 

(cid:116)(cid:1)(cid:1)(cid:39)(cid:80)(cid:83)(cid:1)(cid:69)(cid:70)(cid:67)(cid:85)(cid:1)(cid:84)(cid:70)(cid:68)(cid:86)(cid:83)(cid:74)(cid:85)(cid:74)(cid:70)(cid:84)(cid:13)(cid:1)(cid:74)(cid:71)(cid:1)(cid:85)(cid:73)(cid:70)(cid:1)(cid:36)(cid:80)(cid:78)(cid:81)(cid:66)(cid:79)(cid:90)(cid:1)(cid:74)(cid:79)(cid:85)(cid:70)(cid:79)(cid:69)(cid:84)(cid:1)(cid:85)(cid:80)(cid:1)(cid:70)(cid:74)(cid:85)(cid:73)(cid:70)(cid:83)(cid:1)
sell or determines that it will be more likely than not 
be required to sell a security before recovery of the 
entire amortized cost basis or maturity of the security,yy
the Company recognizes the entire impairment in 
Investment and Other Income. If the Company does not
intend to sell the debt security and it determines that 
it will not be more likely than not be required to sell 
the security but it does not expect to recover the entire 

amortized cost basis, the impairment is bifurcated 
into the amount attributed to the credit loss, which is 
recognized in earnings, and all other causes, which are 
recognized in other comprehensive income.
(cid:116)(cid:1)(cid:1)(cid:39)(cid:80)(cid:83)(cid:1)(cid:70)(cid:82)(cid:86)(cid:74)(cid:85)(cid:90)(cid:1)(cid:84)(cid:70)(cid:68)(cid:86)(cid:83)(cid:74)(cid:85)(cid:74)(cid:70)(cid:84)(cid:13)(cid:1)(cid:85)(cid:73)(cid:70)(cid:1)(cid:36)(cid:80)(cid:78)(cid:81)(cid:66)(cid:79)(cid:90)(cid:1)(cid:83)(cid:70)(cid:68)(cid:80)(cid:72)(cid:79)(cid:74)(cid:91)(cid:70)(cid:84)(cid:1)

impairments in other comprehensive income if it 
expects to hold the security until fair value increases 
to at least the security’s cost basis and it expects 
that increase in fair value to occur in a reasonably 
forecasted period. If the Company intends to sell the 
equity security or if it believes that recovery of fair 
value to cost will not occur in a reasonably forecasted 
period, the Company recognizes the impairment in 
Investment and Other Income.

New information and the passage of time can change 
these judgments. The Company manages its investment 
portfolio to limit its exposure to any one issuer or 
market sector, and largely limits its investments to U.S.
government and agency securities; state and municipal 
securities; mortgage-backed securities; and corporate 
debt obligations, substantially all of investment grade 
quality. Securities downgraded below policy minimums 
after purchase will be disposed of in accordance with the 
investment policy. 

Assets Under Management 
The Company provides health insurance products and 
services to members of AARP under a Supplemental 
Health Insurance Program (the AARP Program), and 
to AARP members and non-members under separate 
Medicare Advantage and Medicare Part D arrangements. 
The products and services under the AARP Program 
include supplemental Medicare benefits (AARP Medicare 
Supplement Insurance), hospital indemnity insurance, 
including insurance for individuals between 50 to 64 years 
of age, and other related products. 

The Company’s arrangements with AARP extend to 
December 31, 2017 for the AARP Program and give the 
Company an exclusive right to use the AARP brand on 
the Company’s Medicare Advantage and Medicare Part D 
offerings until December 31, 2014, subject to certain  
limited exclusions. 

Pursuant to the Company’s agreement, AARP Program 
assets are managed separately from its general investment
portfolio and are used to pay costs associated with the 
AARP Program. These assets are invested at the Company’s 
discretion, within investment guidelines approved by AARP. 
The Company does not guarantee any rates of return on 
these investments and, upon transfer of the AARP Program 
contract to another entity, the Company would transfer 
cash equal in amount to the fair value of these investments 
at the date of transfer to that entity. Because the purpose 
of these assets is to fund the medical costs payable, the 
rate stabilization fund (RSF) liabilities and other related 
liabilities associated with this AARP contract, assets under 
management are classified as current assets, consistent
with the classification of these liabilities. Interest earnings 
and realized investment gains and losses on these assets 
accrue to the overall benefit of the AARP policyholders 

2011 FORM 10-K

through the RSF. Accordingly, they are not included in the 
Company’s earnings. Interest income and realized gains and 
losses related to assets under management are recorded as 
an increase to the RSF and were $99 million, $107 million 
and $99 million in 2011, 2010 and 2009, respectively. 
The effects of changes in balance sheet amounts 

associated with the AARP Program also accrue to the overall 
benefit of the AARP policyholders through the RSF balance. 
Accordingly, the Company excludes the effect of such 
changes in its Consolidated Statements of Cash Flows. For 
more detail on the RSF,  see “Other Policy Liabilities” below.

Other Current Receivables 
Other current receivables include amounts due from 
pharmaceutical manufacturers for rebates and Medicare 
Part D drug discounts, reinsurance and other miscellaneous 
amounts due to the Company. 

The Company’s PBM businesses contract with 

pharmaceutical manufacturers, some of whom provide 
rebates based on use of the manufacturers’ products by its 
PBM businesses’ affiliated and non-affiliated clients. The 
Company accrues rebates as they are earned by its clients 
on a monthly basis based on the terms of the applicable 
contracts, historical data and current estimates. The PBM 
businesses bill these rebates to the manufacturers on a 
monthly or quarterly basis depending on the contractual 
terms. The PBM businesses record rebates attributable to 
affiliated clients as a reduction to medical costs. Rebates 
attributable to non-affiliated clients are accrued as rebates 
receivable and a reduction of cost of products sold with 
a corresponding payable for the amounts of the rebates 
to be remitted to non-affiliated clients in accordance 
with their contracts and recorded in the Consolidated 
Statements of Operations as a reduction of Product 
Revenue. The Company generally receives rebates from two 
to five months after billing. 

For details on the Company’s Medicare Part D receivables 

see “Medicare Part D Pharmacy Benefits” below. 

For details on the Company’s reinsurance receivable see 
“Future Policy Benefits and Reinsurance Receivable” below. 

Medicare Part D Pharmacy Benefits
The Company serves as a plan sponsor offering Medicare 
Part D prescription drug insurance coverage under contracts 
with CMS. Under the Medicare Part D program, there 
are seven separate elements of payment received by the 
Company during the plan year. These payment elements 
are as follows: 

(cid:116) CMS Premium. CMS pays a fixed monthly premium per 

member to the Company for the entire plan year.

(cid:116)(cid:1)(cid:1)Member Premium. Additionally, certain members pay a 
fixed monthly premium to the Company for the entire 
plan year.

(cid:116)(cid:1) Low-Income Premium Subsidy.yy For qualifying low-
income members, CMS pays some or all of the 
member’s monthly premiums to the Company on the 
member’s behalf.

(cid:116)(cid:1)(cid:1)Catastrophic Reinsurance Subsidy.yy CMS pays the 

Company a cost reimbursement estimate monthly to 

54

UNITEDHEALTH GROUP

fund the CMS obligation to pay approximately 80%
of the costs incurred by individual members in excess 
of the individual annual out-of-pocket maximum. A
settlement is made with CMS based on actual cost 
experience, after the end of the plan year.

(cid:116) Low-Income Member Cost Sharing Subsidy.yy For 

qualifying low-income members, CMS pays on the 
member’s behalf some or all of a member’s cost sharing 
amounts, such as deductibles and coinsurance. The cost 
sharing subsidy is funded by CMS through monthly
payments to the Company. The Company administers 
and pays the subsidized portion of the claims on behalf 
of CMS, and a settlement payment is made between 
CMS and the Company based on actual claims and
premium experience, after the end of the plan year.
(cid:116) CMS Risk-Share. Premiums from CMS are subject to 

risk corridor provisions that compare costs targeted in 
the Company’s annual bids by product and region to
actual prescription drug costs, limited to actual costs 
that would have been incurred under the standard
coverage as defined by CMS. Variances of more than 
5% above or below the original bid submitted by
the Company may result in CMS making additional 
payments to the Company or require the Company to 
refund to CMS a portion of the premiums it received. 
The Company estimates and recognizes an adjustment 
to premium revenues related to the risk corridor 
payment settlement based upon pharmacy claims 
experience. The estimate of the settlement associated 
with these risk corridor provisions requires the 
Company to consider factors that may not be certain, 
including member eligibility status differences with 
CMS. The Company records risk-share adjustments to 
Premium Revenues in the Consolidated Statements of 
Operations and Other Policy Liabilities or Other Current
Receivables in the Consolidated Balance Sheets.
(cid:116) Drug Discount. Beginning in 2011, Health Reform

Legislation mandated a consumer discount of 50% 
on brand name prescription drugs for Part D plan 
participants in the coverage gap. This discount is 

funded by CMS and pharmaceutical manufacturers 
while the Company administers the application of 
these funds. Amounts received are not reflected as 
premium revenues, but rather are accounted for 
as deposits. The Company records a liability when 
amounts are received from CMS and a receivable when 
the Company bills the pharmaceutical manufacturers. 
Related cash flows are presented as Customer Funds 
Administered within financing activities in the 
Condensed Consolidated Statements of Cash Flows.

The CMS Premium, the Member Premium, and the 

Low-Income Premium Subsidy represent payments for the 
Company’s insurance risk coverage under the Medicare 
Part D program and therefore are recorded as Premium 
Revenues in the Consolidated Statements of Operations. 
Premium revenues are recognized ratably over the period in 
which eligible individuals are entitled to receive prescription 
drug benefits. The Company records premium payments 
received in advance of the applicable service period in 
Unearned Revenues in the Consolidated Balance Sheets.
The Catastrophic Reinsurance Subsidy and the Low-

Income Member Cost Sharing Subsidy (Subsidies) 
represent cost reimbursements under the Medicare Part 
D program. Amounts received for these Subsidies are not 
reflected as premium revenues, but rather are accounted 
for as receivables and/or deposits. Related cash flows 
are presented as Customer Funds Administered within 
financing activities in the Condensed Consolidated
Statements of Cash Flows.

Pharmacy benefit costs and administrative costs under 
the contract are expensed as incurred and are recognized 
in Medical Costs and Operating Costs, respectively, in the 
Consolidated Statements of Operations. 

The final 2011 risk-share amount is expected to be 

settled during the second half of 2012, and is subject to the 
reconciliation process with CMS. 

The Consolidated Balance Sheets include the following

amounts associated with the Medicare Part D program:

As of January 1, 2012, certain changes were made to the 

Medicare Part D coverage by CMS, including: 

The initial coverage limit increased to $2,930 from 
$2,840 in 2011. 

The catastrophic coverage begins at $6,658 as 
compared to $6,448 in 2011. 

The annual out-of-pocket maximum increased to 
$4,700 from $4,550 in 2011.

Property, Equipment and Capitalized Software 
Property, equipment and capitalized software are stated 
at cost, net of accumulated depreciation and amortization. 
Capitalized software consists of certain costs incurred in the 
development of internal-use software, including external 
direct costs of materials and services and payroll costs of 
employees devoted to specific software development. The 
Company reviews property, equipment and capitalized 
software for events or changes in circumstances that would 
indicate that it might not recover their carrying value. If the 
Company determines that an asset may not be recoverable, 
an impairment charge is recorded. 

 The Company calculates depreciation and amortization 

using the straight-line method over the estimated useful 
lives of the assets. The useful lives for property, equipment 
and capitalized software are: 
Furniture, fixtures and equipment

3 to 7 years

Buildings

Leasehold improvements

35 to 40 years

7 years or length 
of lease term,
whichever is shorter

Capitalized software

3 to 5 years

Goodwill
Goodwill represents the amount of the purchase price
in excess of the fair values assigned to the underlying 
identifiable net assets of acquired businesses. Goodwill 
is not amortized, but is subject to an annual impairment 
test. Tests are performed more frequently if events occur
or circumstances change that would more likely than not 
reduce the fair value of the reporting unit below its 
carrying amount. 

To determine whether goodwill is impaired, the 

Company performs a multi-step impairment test. First, the
Company can elect to perform a qualitative assessment 
of each reporting unit to determine whether facts and 
circumstances support a determination that their fair values 
are greater than their carrying values. If the qualitative 
analysis is not conclusive, or if the Company elects to 
proceed directly with quantitative testing, it will then 
measure the fair values of the reporting units and compare 
them to their aggregate carrying values, including goodwill. 
If the fair value is less than the carrying value of the 
reporting unit, then the implied value of goodwill would 
be calculated and compared to the carrying amount of 
goodwill to determine whether goodwill is impaired.  

The Company estimates the fair values of its reporting 
units using discounted cash flows. To determine fair values, 
the Company must make assumptions about a wide variety 

2011 FORM 10-K

55

of internal and external factors. Significant assumptions 
used in the impairment analysis include financial projections 
of free cash flow (including significant assumptions about 
operations, capital requirements and income taxes), long-
term growth rates for determining terminal value, and 
discount rates. 

The Company elected to bypass the optional qualitative 

reporting-unit fair value assessment and completed its 
annual quantitative test for goodwill impairment as of 
January 1, 2012. As of December 31, 2011, no reporting unit 
had a fair value less than its carrying value and the Company 
concluded that there was no need for any impairment of its 
goodwill balances.

Intangible assets
Finite-lived, separately-identifiable intangible assets are 
acquired in business combinations and are assets that 
represent future expected benefits but lack physical 
substance (e.g., membership lists, customer contracts,
trademarks and technology). The Company does not have 
material holdings of indefinite lived intangible assets. The 
Company’s intangible assets are initially recorded at their 
fair values and are then amortized over their expected 
useful lives. 

The Company’s intangible assets are subject to impairment 

tests when events or circumstances indicate that a finite-
lived intangible asset’s (or asset group’s) carrying value may 
exceed its estimated fair value. Consideration is given to 
a number of potential impairment indicators. Following 
the identification of any potential impairment indicators, 
to determine whether an impairment exists, the Company 
would calculate the estimated fair value of a finite-lived 
intangible asset using the undiscounted cash flows that 
are expected to result from the use of the asset or related
group of assets. Once it is determined that an impairment 
exists, the amount by which the carrying value exceeds the 
estimated fair value is recorded as an impairment.

There were no material impairments of finite-lived 

intangible assets during the year ended December 31, 2011.

Other Policy Liabilities 
Other policy liabilities include the RSF associated with the 
AARP Program (described below), health savings account 
deposits, deposits under the Medicare Part D program 
(see “Medicare Part D Pharmacy Benefits” above), accruals 
for premium rebate payments under the Health Reform 
Legislation, the current portion of future policy benefits 
and customer balances. Customer balances represent excess 
customer payments and deposit accounts under experience-
rated contracts. At the customer’s option, these balances 
may be refunded or used to pay future premiums or claims 
under eligible contracts. 

Underwriting gains or losses related to the AARP Program 

are directly recorded as an increase or decrease to the RSF 
and accrue to the overall benefit of the AARP policyholders, 
unless cumulative net losses were to exceed the balance 
in the RSF. The primary components of the underwriting 
results are premium revenue, medical costs, investment
income, administrative expenses, member service expenses, 
marketing expenses and premium taxes. To the extent 

56

UNITEDHEALTH GROUP

underwriting losses exceed the balance in the RSF, losses 
would be borne by the Company. Deficits may be recovered 
by underwriting gains in future periods of the contract. 
To date, the Company has not been required to fund any
underwriting deficits. Changes in the RSF are reported in 
Medical Costs in the Consolidated Statement of Operations. 
As of December 31, 2011 and 2010, the balance in the RSF 
was $1.3 billion. The Company believes the RSF balance as
of December 31, 2011 is sufficient to cover potential future 
underwriting and other risks and liabilities associated with 
the contract. 

Income Taxes 
Deferred income tax assets and liabilities are recognized 
for the differences between the financial and income tax 
reporting bases of assets and liabilities based on enacted tax 
rates and laws. The deferred income tax provision or benefit 
generally reflects the net change in deferred income tax 
assets and liabilities during the year, excluding any deferred 
income tax assets and liabilities of acquired businesses. The 
current income tax provision reflects the tax consequences 
of revenues and expenses currently taxable or deductible on 
various income tax returns for the year reported. 

Future Policy Benefits and Reinsurance Receivable
Future policy benefits represent account balances that 
accrue to the benefit of the policyholders, excluding 
surrender charges, for universal life and investment annuity 
products and for long-duration health policies sold to
individuals for which some of the premium received in 
the earlier years is intended to pay benefits to be incurred 
in future years. As a result of the 2005 sale of the life 
and annuity business within the Company’s Golden Rule
Financial Corporation subsidiary under an indemnity
reinsurance arrangement, the Company has maintained a 
liability associated with the reinsured contracts, as it remains 
primarily liable to the policyholders, and has recorded 
a corresponding reinsurance receivable due from the 
purchaser. As of December 31, 2011, the Company had an 
aggregate $1.9 billion reinsurance receivable, of which $125 
million was recorded in Other Current Receivables and $1.8 
billion was recorded in Other Assets in the Consolidated 
Balance Sheets. As of December 31, 2010, the Company had 
an aggregate $2.0 billion reinsurance receivable, of which 
$126 million was recorded in Other Current Receivables and 
$1.9 billion was recorded in Other Assets in the Consolidated 
Balance Sheets. The Company evaluates the financial 
condition of the reinsurer and only records the reinsurance 
receivable to the extent of probable recovery. Currently, the 
reinsurer is rated by A.M. Best as “A+.” 

Policy Acquisition Costs 
The Company’s short duration health insurance contracts 
typically have a one-year term and may be cancelled by 
the customer with at least 30 days notice. Costs related to 
the acquisition and renewal of short duration customer 
contracts are charged to expense as incurred. 

Net Earnings Per Common Share 
The Company computes basic net earnings per common 
share by dividing net earnings by the weighted-average

number of common shares outstanding during the 
period. The Company determines diluted net earnings per 
common share using the weighted-average number of 
common shares outstanding during the period, adjusted 
for potentially dilutive shares associated with stock options, 
stock-settled stock appreciation rights (SARs) and restricted 
stock and restricted stock units (collectively, restricted 
shares), using the treasury stock method. The treasury 
stock method assumes exercise of stock options and vesting 
of restricted shares, with the assumed proceeds used to 
purchase common stock at the average market price for 
the period. The difference between the number of shares 
assumed issued and number of shares assumed purchased 
represents the dilutive shares. 

Recent Accounting Standards
Recently Issued Accounting Standards. In July 2011,
the Financial Accounting Standards Board (FASB) issued
Accounting Standards Update (ASU) No. 2011-06, “Other 
Expenses (Topic 720): Fees Paid to the Federal Government 
by Health Insurers a consensus of the FASB Emerging 
Issues Task Force” (ASU 2011-06). This update addresses 
the recognition and classification of an entity’s share of 
the annual health insurance industry assessment (the fee) 
mandated by Health Reform Legislation. The fee will be 
levied on health insurers for each calendar year beginning 
on or after January 1, 2014 and is not deductible for income 
tax purposes. The fee will be allocated to health insurers 
based on the ratio of an entity’s net health premiums 
written during the preceding calendar year to the total 
health insurance for any U.S. health risk that is written 
during the preceding calendar year. In accordance with the
amendments in ASU 2011-06, the liability for the fee will be 
estimated and recorded in full once the Company provides 
qualifying health insurance in the applicable calendar year 
in which the fee is payable (first applicable in 2014) with 
a corresponding deferred cost that will be amortized to 
expense using a straight-line method of allocation unless 
another method better allocates the fee over the calendar 
year that it is payable. 

Recently Adopted Accounting Standards. In September
2011, the FASB issued ASU No. 2011-08, “Intangibles - 
Goodwill and Other (Topic 350): Testing Goodwill for
Impairment” (ASU 2011-08). This update intends to simplify 
how entities test goodwill for impairment by including 
an option for entities to first assess qualitative factors to 
determine whether it is more-likely-than-not that the fair 
value of a reporting unit is less than its carrying amount as 
a basis for determining whether it is necessary to perform 
the two-step goodwill impairment test on the subject 
reporting unit. The Company adopted the amendments in
ASU 2011-08 for its annual goodwill impairment test as of 
January 1, 2012. The adoption of ASU 2011-08 did not
have a material impact on the Company’s Consolidated 
Financial Statements.

The Company has determined that there have been no 
other recently issued or adopted accounting standards that 
will have or had a material impact on its Consolidated 
Financial Statements.

The unrealized losses from all securities as of December 31, 2011 were generated from 2,100 positions out of a total of 

15,300 positions. The Company believes that it will collect the principal and interest due on its investments that have an 
amortized cost in excess of fair value. The unrealized losses on investments in state and municipal obligations and corporate 
obligations as of December 31, 2011 were primarily caused by interest rate increases and not by unfavorable changes in the 
credit ratings associated with these securities. At each reporting period, the Company evaluates securities for impairment 
when the fair value of the investment is less than its amortized cost. The Company evaluated the underlying credit quality 
of the issuers and the credit ratings of the state and municipal obligations and the corporate obligations, noting neither 
a significant deterioration since purchase nor other factors leading to an other-than-temporary impairment (OTTI). As of 
December 31, 2011, the Company did not have the intent to sell any of the securities in an unrealized loss position.

As of December 31, 2011, the Company’s holdings of non-U.S. agency mortgage-backed securities included $7 million of 

commercial mortgage loans in default. They represented less than 1% of the Company’s total mortgage-backed security 
holdings as of December 31, 2011.

A portion of the Company’s investments in equity securities and venture capital funds consists of investments held 
in various public and nonpublic companies concentrated in the areas of health care services and related information 
technologies. Market conditions that affect the value of health care and related technology stocks will likewise impact the 
value of the Company’s equity portfolio. The equity securities and venture capital funds were evaluated for severity and 
duration of unrealized loss, overall market volatility and other market factors.

Net realized gains included in Investment and Other Income on the Consolidated Statements of Operations were from the 

following sources:

4.  FAIR VALUE
Certain assets and liabilities are measured at fair value in 
the financial statements. These assets and liabilities are 
classified into one of three levels of a hierarchy defined 
by U.S. GAAP. In instances in which the inputs used to 
measure fair value fall into different levels of the fair value 
hierarchy, the fair value measurement has been determined 
based on the lowest level input that is significant to the 
fair value measurement in its entirety. The Company’s 
assessment of the significance of a particular item to the 
fair value measurement in its entirety requires judgment, 
including the consideration of inputs specific to the asset
or liability. 

The fair value hierarchy is summarized as follows:
Level 1 — Quoted (unadjusted) prices for identical assets/

liabilities in active markets.

Level 2 — Other observable inputs, either directly or

indirectly, including:

(cid:116) (cid:50)(cid:86)(cid:80)(cid:85)(cid:70)(cid:69)(cid:1)(cid:81)(cid:83)(cid:74)(cid:68)(cid:70)(cid:84)(cid:1)(cid:71)(cid:80)(cid:83)(cid:1)(cid:84)(cid:74)(cid:78)(cid:74)(cid:77)(cid:66)(cid:83)(cid:1)(cid:66)(cid:84)(cid:84)(cid:70)(cid:85)(cid:84)(cid:16)(cid:77)(cid:74)(cid:66)(cid:67)(cid:74)(cid:77)(cid:74)(cid:85)(cid:74)(cid:70)(cid:84)(cid:1)(cid:74)(cid:79)(cid:1)(cid:66)(cid:68)(cid:85)(cid:74)(cid:87)(cid:70)

for the asset/liability (e.g., interest rates, yield curves, 
volatilities, default rates); and

(cid:116) (cid:42)(cid:79)(cid:81)(cid:86)(cid:85)(cid:84)(cid:1)(cid:85)(cid:73)(cid:66)(cid:85)(cid:1)(cid:66)(cid:83)(cid:70)(cid:1)(cid:69)(cid:70)(cid:83)(cid:74)(cid:87)(cid:70)(cid:69)(cid:1)(cid:81)(cid:83)(cid:74)(cid:79)(cid:68)(cid:74)(cid:81)(cid:66)(cid:77)(cid:77)(cid:90)(cid:1)(cid:71)(cid:83)(cid:80)(cid:78)(cid:1)(cid:80)(cid:83)(cid:1)(cid:68)(cid:80)(cid:83)(cid:83)(cid:80)(cid:67)(cid:80)(cid:83)(cid:66)(cid:85)(cid:70)(cid:69)

that rely heavily on management assumptions and 
qualitative observations. These investments totaled $168 
million and $166 million as of December 31, 2011 and 
2010, respectively. The fair values of the Company’s various 
venture capital investments are computed using limited 
quantitative and qualitative observations of activity for 
similar companies in the current market. The key inputs 
utilized in the Company’s market modeling include, as 
applicable, transactions for comparable companies in 
similar industries and having similar revenue and growth 
characteristics; similar preferences in the capital structure; 
discounted cash flows; liquidation values and milestones 
established at initial funding; and the assumption that the 
values of the Company’s venture capital investments can be 
inferred from these inputs. The Company’s remaining Level 
3 equity securities holdings of $41 million and $42 million 
as of December 31, 2011 and 2010, respectively, consist of 
preferred stock and other items for which there are no 
active markets. 

Throughout the procedures discussed above in relation to

the Company’s processes for validating third party pricing 
information, the Company validates the understanding 
of assumptions and inputs used in security pricing and 
determines the proper classification in the hierarchy based 
on that understanding.

Interest Rate Swaps. Fair values of the Company’s interest 
rate swaps were estimated using the terms of the swaps 
and publicly available market yield curves. Because the 
swaps were unique and not actively traded, the fair values 
were classified as Level 2.

AARP Program-related Investments. AARP Program-related 
investments consist of debt and equity securities held to 
fund costs associated with the AARP Program and are 
priced and classified using the same methodologies as the 
Company’s other securities.

Senior Unsecured Notes. The fair values of the senior 
unsecured notes are estimated based on third-party quoted 
market prices for the same or similar issues.

AARP Program-related Other Liabilities. AARP Program-
related other liabilities consist of liabilities that represent 
the amount of net investment gains and losses related 
to AARP Program-related investments that accrue to the 
benefit of the AARP policyholders.

UNITEDHEALTH GROUP

The carrying amounts reported in the Consolidated 

Balance Sheets for cash and cash equivalents, accounts and 
other current receivables, unearned revenues, commercial 
paper, accounts payable and accrued liabilities approximate 
fair value because of their short-term nature. These assets 
and liabilities are not listed in the table above.

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

Cash and Cash Equivalents. The carrying value of cash
and cash equivalents approximates fair value as maturities 
are less than three months. Fair values of cash equivalent 
instruments that do not trade on a regular basis in active 
markets are classified as Level 2.

Debt and Equity Securities. Fair values of available-for-sale 
debt and equity securities are based on quoted market 
prices, where available. The Company obtains one price for
each security primarily from a third-party pricing service 
(pricing service), which generally uses quoted or other
observable inputs for the determination of fair value. 
The pricing service normally derives the security prices 
through recently reported trades for identical or similar 
securities, making adjustments through the reporting date 
based upon available observable market information. 
For securities not actively traded, the pricing service may 
use quoted market prices of comparable instruments or 
discounted cash flow analyses, incorporating inputs that are
currently observable in the markets for similar securities. 
Inputs that are often used in the valuation methodologies 
include, but are not limited to, benchmark yields, credit 
spreads, default rates, prepayment speeds and non-binding
broker quotes. As the Company is responsible for the 
determination of fair value, it performs quarterly analyses 
on the prices received from the pricing service to determine 
whether the prices are reasonable estimates of fair value. 
Specifically, the Company compares the prices received 
from the pricing service to a secondary pricing source, 
prices reported by its custodian, its investment consultant 
and third-party investment advisors. Additionally, the 
Company compares changes in the reported market 
values and returns to relevant market indices to test the 
reasonableness of the reported prices. The Company’s 
internal price verification procedures and review of 
fair value methodology documentation provided by
independent pricing services has not historically resulted in 
adjustment in the prices obtained from the pricing service.

Fair values of debt securities that do not trade on a 
regular basis in active markets but are priced using other 
observable inputs are classified as Level 2. The Company’s 
Level 3 debt securities consist mainly of low income housing 
investments that are unique and non-transferable.

Fair value estimates for Level 1 and Level 2 publicly 

traded equity securities are based on quoted market prices 
and/or other market data for the same or comparable 
instruments and transactions in establishing the prices. 
The fair values of Level 3 investments in venture capital 
portfolios are estimated using market modeling approaches

(a)Prior period reportable segment financial information has been recast to conform to the 2011 presentation as discussed 
in Note 2 of Notes to the Consolidated Financial Statements.

In 2010, there was a decline in the economic environment and competitive landscape for the clinical trial support businesses 
within one of the OptumInsight reporting units. These businesses experienced unexpected declines in new business 
authorizations from historical levels including continued delays in and lengthening of the selling cycle. During this time the 
Company began evaluating strategic options with respect to the clinical trial support businesses. In December 2010, as part 
of the annual goodwill impairment analysis, the Company considered the aforementioned market conditions and operating 
results as well as indications of interest the Company began to receive on the clinical trial support businesses as the fair 
value of the reporting unit was evaluated. As a result of that analysis, the Company determined that the implied fair value 
of the reporting unit was less than its carrying value and an impairment charge of $172 million was recorded. The implied 
fair value of the reporting unit was determined by a combination of valuation techniques, including discounting future 
expected cash flows and expected sale proceeds. The Company sold a significant portion of this reporting unit in 2011 
resulting in a reduction of goodwill upon disposal.

7.  MEDICAL COSTS AND MEDICAL COSTS PAYABLE
For the year ended December 31, 2011, there was $720 million of net favorable medical cost development related to prior 
fiscal years. The favorable development in 2011 was primarily driven by continued improvements in claims submission 
timeliness, which results in higher completion factors, and lower than expected health system utilization levels.

For the year ended December 31, 2010, there was $800 million of net favorable medical cost development related to prior 
fiscal years. The favorable development in 2010 was primarily driven by lower than expected health system utilization levels; 
more efficient claims handling and processing, which results in higher completion factors; a reduction in reserves needed for 
disputed claims from care providers; and favorable resolution of certain state-based assessments. 

No factor (e.g., medical trends/utilization, completion factors) was individually material to the $310 million of net 

favorable medical cost development for the year ended December 31, 2009.

Commercial Paper and Bank Credit Facility
Commercial paper consists of short-duration, senior 
unsecured debt privately placed on a discount basis 
through broker-dealers.  

In December 2011, the Company amended and renewed 

its five-year revolving bank credit facility with 21 banks, 
which will mature in December 2016. The amendment 
included increasing the capacity to $3.0 billion. This facility 
supports the Company’s commercial paper program and is 
available for general corporate purposes. There were no 
amounts outstanding under this facility as of December 31, 
2011. The interest rate on borrowings is variable based on 
term and amount and is calculated based on the London 
Interbank Offered Rate (LIBOR) plus a credit spread based 
on the Company’s senior unsecured credit ratings. As of 
December 31, 2011, the annual interest rate on this facility, 
had it been drawn, would have ranged from 1.2% to 1.7%.

Debt Covenants
The Company’s bank credit facility contains various 
covenants including requiring the Company to maintain 
a debt-to-total-capital ratio, calculated as debt divided by 
the sum of debt and shareholders’ equity, below 50%. The 
Company was in compliance with its debt covenants as of 
December 31, 2011.

Interest Rate Swap Contracts
During 2010, the Company entered into interest rate swap 
contracts to convert a portion of its interest rate exposure 
from fixed to floating rates. The interest rate swap 
contracts were benchmarked to LIBOR and were utilized 
to more closely align interest expense with interest income 
received on the Company’s cash equivalent and investment 
balances. The swaps were designated as fair value hedges 
on fixed-rate debt issues maturing between November 

2011 FORM 10-K

67

2012 through March 2016 and June 2017 through October 
2020. Since the specific terms and notional amounts of the 
swaps matched those of the debt being hedged, they were 
assumed to be highly effective hedges and all changes in 
fair value of the swaps were recorded on the Consolidated 
Balance Sheets with no net impact recorded in the 
Consolidated Statements of Operations.

The following table provides a summary of the effect 
of changes in fair value of fair value hedges, prior to their 
termination, on the Company’s Consolidated Statements of 
Operations:

In the second half of 2011, the Company terminated 
all of its interest rate swap fair value hedges ($5.4 billion 
notional amount). As of the swap contracts’ termination 
dates, the aggregate favorable adjustments to the carrying 
value of the Company’s debt of $132 million is being 
amortized as a reduction to interest expense over the 
remaining lives of the underlying debt obligations, which 
had in total a weighted-average life of 4.1 years. For the 
year ended December 31, 2011, the net impact of the gain 
amortization was not material. The purpose of the interest 
rate swap terminations was to lock-in the impact of low 
market floating interest rates and reduce the effective 
interest rate on hedged long-term debt.

The lower effective income tax rates for 2011 and 2009 as compared to 2010 resulted from the favorable resolution of 
various tax matters as well as higher effective income tax rates in 2010. The 2010 effective income tax rates were at higher 
levels due to the cumulative implementation of changes under the Health Reform Legislation.

Valuation allowances are provided when it is considered more likely than not that deferred tax assets will not be 
realized. The valuation allowances primarily relate to future tax benefits on certain federal and state net operating loss 
carryforwards. Federal net operating loss carryforwards of $151 million expire beginning in 2019 through 2031, and state 
net operating loss carryforwards expire beginning in 2012 through 2031.

The Company classifies interest and penalties associated with uncertain income tax positions as income taxes within its 
Consolidated Financial Statements. During the year ended December 31, 2011, the Company recognized a tax benefit of
$12 million generated from the net reduction in interest and penalties accrued. During the year ended December 31, 2010,
the Company recognized $15 million of interest expense and penalties. During the year ended December 31, 2009, the 
Company recognized a tax benefit of $7 million generated from the net reduction in interest accrued. The Company had 
$41 million and $63 million of accrued interest and penalties for uncertain tax positions as of December 31, 2011 and 2010, 
respectively. These amounts are not included in the reconciliation above. As of December 31, 2011, the total amount of
unrecognized tax benefits that, if recognized, would affect the effective tax rate, was $90 million.

Corporation (FDIC) to be considered “Well Capitalized” 
under the capital adequacy rules to which it is subject. 
At December 31, 2011, the Company believes that 
OptumHealth Bank met the FDIC requirements to be 
considered “Well Capitalized”. 

Share Repurchase Program
Under its Board of Directors’ authorization, the Company 
maintains a share repurchase program. The objectives 
of the share repurchase program are to optimize the 
Company’s capital structure and cost of capital, thereby 
improving returns to shareholders, as well as to offset the 
dilutive impact of share-based awards. Repurchases may be 
made from time to time in open market purchases or other 
types of transactions (including prepaid or structured share 
repurchase programs), subject to certain Board restrictions. 
In May 2011, the Board renewed the Company’s share 
repurchase program with an authorization to repurchase 
up to 110 million shares of its common stock. During 2011, 
the Company repurchased 65 million shares at an average 
price of approximately $46 per share and an aggregate cost 
of $3.0 billion. As of December 31, 2011, the Company had 
Board authorization to purchase up to an additional 65 
million shares of its common stock. 

Dividends
In May 2011, the Company’s Board of Directors increased 
the Company’s cash dividend to shareholders to an annual 
dividend rate of $0.65 per share, paid quarterly. Since June 
2010, the Company had paid a quarterly dividend of $0.125 
per share. Declaration and payment of future quarterly 
dividends is at the discretion of the Board and may be 
adjusted as business needs or market conditions change. 
On February 8, 2012, the Company’s Board of Directors 
approved a quarterly dividend of $0.1625 per share.

The Company currently files income tax returns in the U.S. 
federal jurisdiction, various states and foreign jurisdictions. 
The U.S. Internal Revenue Service (IRS) has completed 
exams on the consolidated income tax returns for fiscal 
years 2010 and prior. The Company’s 2011 tax year is under 
advance review by the IRS under its Compliance Assurance 
Program. With the exception of a few states, the Company 
is no longer subject to income tax examinations prior to 
2004. The Company does not believe any adjustments that 
may result from these examinations will be significant. 

The Company believes it is reasonably possible that its 
liability for unrecognized tax benefits will decrease in the 
next twelve months by $73 million as a result of audit 
settlements and the expiration of statutes of limitations in 
certain major jurisdictions. 

10.  SHAREHOLDERS’ EQUITY

Regulatory Capital and Dividend Restrictions 
The Company’s regulated subsidiaries are subject to 
regulations and standards in their respective states of 
domicile. Most of these regulations and standards conform 
to those established by the National Association of 
Insurance Commissioners. These standards, among other 
things, require these subsidiaries to maintain specified 
levels of statutory capital, as defined by each state, and 
restrict the timing and amount of dividends and other 
distributions that may be paid to their parent companies. 
Except in the case of extraordinary dividends, these 
standards generally permit dividends to be paid from 
statutory unassigned surplus of the regulated subsidiary 
and are limited based on the regulated subsidiary’s level 
of statutory net income and statutory capital and surplus. 
These dividends are referred to as “ordinary dividends” and 
generally can be paid without prior regulatory approval. 
If the dividend, together with other dividends paid within 
the preceding twelve months, exceeds a specified statutory 
limit or is paid from sources other than earned surplus, it is 
generally considered an “extraordinary dividend” and must 
receive prior regulatory approval. 

In 2011, based on the 2010 statutory net income 
and statutory capital and surplus levels, the maximum 
amount of ordinary dividends which could be paid was 
$3.4 billion. For the year ended December 31, 2011, 
the Company’s regulated subsidiaries paid their parent 
companies dividends of $4.5 billion, including $1.1 billion 
of extraordinary dividends. For the year ended December 
31, 2010, the Company’s regulated subsidiaries paid their 
parent companies dividends of $3.2 billion, including $686 
million of extraordinary dividends. As of December 31, 
2011, $1.6 billion of the Company’s $9.4 billion of cash and 
cash equivalents was held by non-regulated entities. 
The Company’s regulated subsidiaries had estimated

aggregate statutory capital and surplus of approximately $12 
billion as of December 31, 2011; regulated entity statutory 
capital exceeded state minimum capital requirements.

11.  SHARE-BASED COMPENSATION
In May 2011, the Company’s shareholders approved the 
2011 Stock Incentive Plan (Plan). The Plan is intended to
attract and retain employees and non-employee directors, 
offer them incentives to put forth maximum efforts 
for the success of the Company’s business and afford 
them an opportunity to acquire a proprietary interest 
in the Company. The Plan allows the Company to grant
stock options, stock appreciation rights, restricted stock, 
restricted stock units, performance awards or other stock-
based awards to eligible employees and non-employee
directors. The Plan incorporates the following plans 
adopted by the Company: 2002 Stock and Incentive Plan,
1991 Stock and Incentive Plan, 1998 Broad-Based Stock

Incentive Plan and Non-employee Director Stock Option
Plan. All outstanding stock options, restricted stock and 
other awards issued under the prior plans will remain 
subject to the terms and conditions of the plans under 
which they were issued.

As of December 31, 2011, the Company had 50 million 
shares available for future grants of share-based awards
under its share-based compensation plan, including, but 
not limited to, incentive or non-qualified stock options,
SARs and up to 23 million of awards in restricted shares. The
Company’s outstanding share-based awards consist mainly of
non-qualified stock options, SARs and restricted shares.

Stock Options and SARs
Stock options and SARs vest ratably over four to six years and may be exercised up to 10 years from the date of grant. Stock 
option and SAR activity for the year ended December 31, 2011 is summarized in the table below:

Risk-free interest rates are based on U.S. Treasury yields in effect at the time of grant. Expected volatilities are based on 
the historical volatility of the Company’s common stock and the implied volatility from exchange-traded options on the
Company’s common stock. Expected dividend yields are based on the per share dividend declared by the Company’s Board 
of Directors. The Company uses historical data to estimate option and SAR exercises and forfeitures within the valuation 
model. The expected lives of options and SARs granted represents the period of time that the awards granted are expected 
to be outstanding based on historical exercise patterns.

The weighted-average grant date fair value of stock options and SARs granted for 2011, 2010 and 2009 was

approximately $15 per share, $13 per share and $10 per share, respectively. The total intrinsic value of stock options and 
SARs exercised during 2011, 2010 and 2009 was $327 million, $164 million and $282 million, respectively.

Restricted Shares
Restricted shares vest ratably over three to four years.
Compensation expense related to restricted shares is based 
on the share price on date of grant. Restricted share activity 
for the year ended December 31, 2011 is summarized in the

vested during 2011, 2010 and 2009 was $113 million, $99 
million and $56 million, respectively. 

Employee Stock Purchase Plan 
The Company’s Employee Stock Purchase Plan (ESPP) is 
intended to enhance employee commitment to the goals 
of the Company, by providing a means of achieving stock 
ownership at advantageous terms to eligible employees of 
the Company. Eligible employees are allowed to purchase 
the Company’s stock at a discounted price, which is 85% 
of the lower market price of the Company’s common 
stock at the beginning or at the end of the six-month 
purchase period. During 2011, 2010 and 2009, 3 million 
shares, 4 million shares and 4 million shares of common 
stock, respectively, were purchased under the ESPP. The 
compensation expense is included in the compensation 
expense amounts recognized and discussed below. As 
of December 31, 2011, there were 22 million shares of 
common stock available for issuance under the ESPP. 

Share-Based Compensation Recognition
The Company recognizes compensation expense for 
share-based awards, including stock options, SARs and 
restricted shares, on a straight-line basis over the related 
service period (generally the vesting period) of the award, 
or to an employee’s eligible retirement date under the 
award agreement, if earlier. For 2011, 2010 and 2009 the 
Company recognized compensation expense related to 
its share-based compensation plans of $401 million ($260 
million net of tax effects), $326 million ($278 million 
net of tax effects) and $334 million ($220 million net 
of tax effects), respectively. Share-based compensation 
expense is recognized in Operating Costs in the Company’s 
Consolidated Statements of Operations. As of December 
31, 2011, there was $387 million of total unrecognized 
compensation cost related to share awards that is expected 
to be recognized over a weighted-average period of 1.0 
year. For 2011, 2010 and 2009 the income tax benefit

realized from share-based award exercises was $170 million, 
$78 million and $94 million, respectively.

Other Employee Benefit Plans 
The Company also offers a 401(k) plan for all employees. 
Compensation expense related to this plan was not 
material for the years 2011, 2010 and 2009. 

In addition, the Company maintains non-qualified, 
unfunded deferred compensation plans, which allow 
certain members of senior management and executives to 
defer portions of their salary or bonus and receive certain 
Company contributions on such deferrals, subject to plan 
limitations. The deferrals are recorded within Long-Term 
Investments with an approximately equal amount in Other 
Liabilities in the Consolidated Balance Sheets. The total 
deferrals are distributable based upon termination of 
employment or other periods, as elected under each plan 
and were $281 million and $258 million as of December 31, 
2011 and 2010, respectively. 

12.  COMMITMENTS AND CONTINGENCIES
The Company leases facilities and equipment under long-
term operating leases that are non-cancelable and expire 
on various dates through 2028. Rent expense under all 
operating leases for 2011, 2010 and 2009 was $295 million, 
$297 million and $303 million, respectively.

As of December 31, 2011, future minimum annual lease 
payments, net of sublease income, under all non-cancelable 
operating leases were as follows:

The Company provides guarantees related to its 

performance under certain contracts. If standards are not 
met, the Company may be financially at risk up to a stated 
percentage of the contracted fee or a stated dollar amount. 
Amounts accrued for performance guarantees were not 
material as of December 31, 2011 and 2010. 

As of December 31, 2011, the Company has outstanding, 

undrawn letters of credit with financial institutions of 
$72 million and surety bonds outstanding with insurance 
companies of $316 million, primarily to bond contractual 
performance.

LEGAL MATTERS
Because of the nature of its businesses, the Company is 
frequently made party to a variety of legal actions and 
regulatory inquiries, including class actions and suits 
brought by members, providers, customers and regulators, 
relating to the Company’s management and administration 
of health benefit plans. These matters include medical 
malpractice, employment, intellectual property, antitrust, 
privacy and contract claims, and claims related to health 
care benefits coverage and other business practices.

UNITEDHEALTH GROUP

The Company records liabilities for its estimates of 

probable costs resulting from these matters where 
appropriate. Estimates of probable costs resulting from 
legal and regulatory matters involving the Company 
are inherently difficult to predict, particularly where 
the matters: involve indeterminate claims for monetary 
damages or may involve fines, penalties or punitive 
damages; present novel legal theories or represent a 
shift in regulatory policy; involve a large number of 
claimants or regulatory bodies; are in the early stages of 
the proceedings; or could result in a change in business
practices. Accordingly, the Company is often unable to 
estimate the losses or ranges of losses for those matters 
where there is a reasonable possibility or it is probable that 
a loss may be incurred.

Litigation Matters
Out-of-Network Reimbursement Litigation. In 2000, 
a group of plaintiffs including the American Medical 
Association filed a lawsuit against the Company asserting a 
variety of claims challenging the Company’s determination 
of reimbursement amounts for non-network health 
care services based on the Company’s use of a database 
previously maintained by Ingenix, Inc. (now known as
OptumInsight). The parties entered into a settlement 
agreement in 2009 and this class action lawsuit, along 
with a related industry-wide investigation by the New 
York Attorney General, is now resolved. The Company 
remains a party to a number of other lawsuits challenging 
the determination of out of network reimbursement 
amounts based on use of the same database, including 
putative class actions and multidistrict litigation brought on 
behalf of members of Aetna and WellPoint. The Company 
was dismissed as a party from a similar lawsuit involving 
Cigna and its members. These suits allege, among other 
things, that the database licensed to these companies by 
Ingenix was flawed and that Ingenix conspired with these
companies to underpay their members’ claims and seek 
unspecified damages and treble damages, injunctive and 
declaratory relief, interest, costs and attorneys fees. The 
Company is vigorously defending these suits. The Company
cannot reasonably estimate the range of loss, if any, that 
may result from these matters due to the procedural status 
of the cases, motions to dismiss that are pending in several 
of the cases, the absence of class certification in any of 
the cases, the lack of a formal demand on the Company 
by the plaintiffs, and the involvement of other insurance 
companies as defendants.

California Claims Processing Matter. In 2007, the 
California Department of Insurance (CDI) examined the 
Company’s PacifiCare health insurance plan in California.
The examination findings related to the timeliness and 
accuracy of claims processing, interest payments, provider 
contract implementation, provider dispute resolution and 
other related matters. On January 25, 2008, the CDI issued 
an Order to Show Cause to PacifiCare Life and Health 
Insurance Company, a subsidiary of the Company, alleging
violations of certain insurance statutes and regulations 

in connection with the CDI’s examination findings. On
June 3, 2009, the Company filed a Notice of Defense to 
the Order to Show Cause denying all material allegations 
and asserting certain defenses. The matter has been the 
subject of an administrative hearing before a California 
administrative law judge since December 2009. CDI 
amended its Order to Show Cause three times in 2010 to 
allege a total of 992,936 violations, the large majority 
of which relate to an alleged failure to include certain 
language in standard claims correspondence during a four
month period in 2007. Although we believe that CDI has
never issued an aggregate penalty in excess of $8 million, 
CDI has previously alleged in press reports and releases that 
the Company could theoretically be subject to penalties of 
up to $10,000 per violation. In October 2011, CDI stated 
that it is seeking an average penalty of approximately $326 
per alleged violation. CDI has since reduced the number
of alleged violations to 919,574 but has indicated that it is 
still seeking an aggregate penalty of approximately $325 
million. The Company is vigorously defending against
the claims in this matter and believes that the penalty 
requested by CDI is excessive and without merit. After the 
administrative law judge issues a ruling at the conclusion of 
the administrative proceeding, expected sometime in 2012, 
the California Insurance Commissioner may accept, reject or 
modify the administrative law judge’s ruling, issue his own 
decision, and impose a fine or penalty. The Commissioner’s 
decision is subject to challenge in court. The Company
cannot reasonably estimate the range of loss, if any, that 
may result from this matter given the procedural status 
of the dispute, the novel legal issues presented (including
the legal basis for the majority of the alleged violations), 
the inherent difficulty in predicting regulatory fines and 
penalties, and the various remedies and levels of judicial 
review available to the Company in the event a fine or 
penalty is assessed.

Government Regulation
The Company’s business is regulated at federal, state, local 
and international levels. The laws and rules governing
the Company’s business and interpretations of those laws 
and rules are subject to frequent change. Broad latitude 
is given to the agencies administering those regulations. 
Further, the Company must obtain and maintain regulatory 
approvals to market and sell many of its products.

The Company has been and is currently involved in

various governmental investigations, audits and reviews. 
These include routine, regular and special investigations, 
audits and reviews by CMS, state insurance and health 
and welfare departments, state attorneys general, the 
Office of Inspector General (OIG), the Office of Personnel 
Management, the Office of Civil Rights, the Federal Trade 
Commission, U.S. Congressional committees, the U.S. 
Department of Justice, U.S. Attorneys, the SEC, the IRS, the 
U.S. Department of Labor, the Federal Deposit Insurance 
Corporation and other governmental authorities. For 
example, in the fourth quarter of 2011, CMS conducted an 
audit of the Company’s Medicare Advantage and Part D 
business. The Company is in the process of responding to 

2011 FORM 10-K

73

the actuarial soundness of the bids. On February 3, 2011, 
CMS notified the Company that CMS was evaluating all 
comments received on the proposed methodology and 
that it anticipated making changes to the draft, based on 
input CMS had received. As of the date of this filing, CMS 
has not published the revised methodology. Depending on 
the methodology utilized, potential payment adjustments 
could have a material adverse effect on the Company’s 
results of operations, financial position and cash flows.
The Office of Inspector General for HHS has audited 

our risk adjustment data for two local plans and has 
initially communicated its findings. While the Company 
does not believe OIG has governing authority to directly 
impose payment adjustments for risk adjustment audits 
of Medicare health plans operated under the regulatory 
authority of CMS, the OIG can recommend to CMS a 
proposed payment adjustment, and the Company is unable 
to predict the outcome of this audit process.

Guaranty Fund Assessments. Under state guaranty 
assessment laws, certain insurance companies (and health 
maintenance organizations in some states), including 
those issuing health (which includes long-term care), life 
and accident insurance policies, doing business in those 
states can be assessed (up to prescribed limits) for certain 
obligations to the policyholders and claimants of insolvent 
insurance companies that write the same line or lines of 
business. Assessments are generally based on premiums 
in the state compared to the premiums of other insurers, 
and could be spread out over a period of years. Some 
states permit member insurers to recover assessments paid
through full or partial premium tax offsets.

The Pennsylvania Insurance Commissioner has placed 
Penn Treaty Network America Insurance Company and its 
subsidiary (Penn Treaty), neither of which is affiliated with 
the Company, in rehabilitation, an intermediate action 
before insolvency, and has petitioned a state court for 
liquidation. If Penn Treaty is liquidated, the Company’s 
insurance entities and other insurers may be required to 
pay a portion of Penn Treaty’s policyholder claims through 
guaranty association assessments in future periods. The 
Company has estimated a potential assessment of $250 
million to $350 million related to this matter, and the 
Company would accrue the assessment in operating costs 
if and when the state court renders such a decision. The 
timing, actual amount and impact, if any, of any guaranty 
fund assessments will depend on several factors, including 
if and when the court declares Penn Treaty insolvent, the 
amount of the insolvency, the availability and amount of 
any potential offsets, such as an offset of any premium 
taxes otherwise payable by the Company, and the impact 
of any such assessments on potential premium rebate 
payments under the Health Reform Legislation.

preliminary findings. Other examples of audits include the 
risk adjustment data validation (RADV) audits discussed 
below and a review by the U.S. Department of Labor of 
the Company’s administration of applicable customer 
employee benefit plans with respect to the Employee 
Retirement Income Security Act of 1974, as amended 
(ERISA) compliance.

Government actions can result in assessment of damages, 

civil or criminal fines or penalties, or other sanctions, 
including loss of licensure or exclusion from participation in 
government programs and could have a material adverse 
effect on the Company’s results of operations, financial 
position and cash flows.

Risk Adjustment Data Validation Audits. CMS adjusts 
capitation payments to Medicare Advantage plans and 
Medicare Part D plans according to the predicted health 
status of each beneficiary as supported by data from health 
care providers as well as, for Medicare Part D plans only, 
based on comparing costs predicted in the Company’s 
annual bids to actual prescription drug costs. The Company 
collects claim and encounter data from providers, who the 
Company generally relies on to appropriately code their 
claim submissions and document their medical records. 
CMS then determines the risk score and payment amount 
for each enrolled member based on the health care data 
submitted and member demographic information.

In 2008, CMS announced that it would perform RADV 
audits of selected Medicare Advantage health plans each 
year to validate the coding practices of and supporting 
documentation maintained by health care providers. These 
audits involve a review of medical records maintained by 
providers and may result in retrospective adjustments to 
payments made to health plans. Certain of the Company’s 
health plans have been selected for audit. These audits 
are focused on medical records supporting risk adjustment 
data for 2006 that were used to determine 2007 payment 
amounts. Although these audits are ongoing, the Company 
does not believe they will have a material impact on the 
Company’s results of operations, financial position or 
cash flows.

In December 2010, CMS published for public comment 

a new proposed RADV audit and payment adjustment 
methodology. The proposed methodology contains 
provisions allowing retroactive contract level payment 
adjustments for the year audited using an extrapolation of 
the “error rate” identified in audit samples. The Company 
has submitted comments to CMS regarding concerns the 
Company has with CMS’ proposed methodology. These 
concerns include, among others, the fact that the proposed 
methodology does not take into account the “error rate” in 
the original Medicare fee-for-service data that was used to 
develop the risk adjustment system. Additionally, payments 
received from CMS, as well as benefits offered and 
premiums charged to members, are based on actuarially 
certified bids that did not include any assumption of 
retroactive audit payment adjustments. The Company 
believes that applying retroactive audit and payment 
adjustments after CMS acceptance of bids undermines 

(cid:116)(cid:1)(cid:1)OptumRx offers a multitude of pharmacy benefit 

x

management services including providing prescribed 
medications, patient support and clinical programs. 
OptumRx also provides claims processing, retail 
network contracting, rebate contracting and 
management and clinical programs, such as step 
therapy, formulary management and disease/drug 
therapy management programs to achieve a low-cost, 
high-quality pharmacy benefit.

The Company’s accounting policies for reportable 
segment operations are consistent with those described 
in the Summary of Significant Accounting Policies (see 
Note 2 of Notes to the Consolidated Financial Statements). 
Transactions between reportable segments principally 
consist of sales of pharmacy benefit products and services 
to UnitedHealthcare customers by OptumRx, certain 
product offerings sold to UnitedHealthcare customers 
by OptumHealth, and medical benefits cost, quality 
and utilization data and predictive modeling sold to
UnitedHealthcare by OptumInsight. These transactions 
are recorded at management’s estimate of fair value. 
Intersegment transactions are eliminated in consolidation. 
Assets and liabilities that are jointly used are assigned 
to each reportable segment using estimates of pro-rata 
usage. Cash and investments are assigned such that each 
reportable segment has at least minimum specified levels 
of regulatory capital or working capital for non-regulated
businesses. Substantially all of the Company’s assets are 
held and operations are conducted in the United States. 
As a percentage of the Company’s total consolidated 
revenues, premium revenues from CMS were 28% for the 
year ended December 31, 2011 and 27% for both the years 
ended December 31, 2010 and 2009, most of which were 
generated by UnitedHealthcare Medicare & Retirement and 
included in the UnitedHealthcare segment.

Prior period reportable segment financial information 
has been recast to conform to the 2011 presentation as 
discussed in Note 2 of Notes to the Consolidated Financial 
Statements. Corporate and intersegment eliminations 
are presented to reconcile the reportable segment results 
to the consolidated results. The following table presents 
reportable segment financial information:

UNITEDHEALTH GROUP

13.  SEGMENT FINANCIAL INFORMATION
Factors used in determining the Company’s reportable 
segments include the nature of operating activities, 
economic characteristics, existence of separate senior 
management teams and the type of information presented 
to the Company’s chief operating decision-maker to 
evaluate its results of operations. Reportable segments with 
similar economic characteristics are combined. 

The following is a description of the types of products 
and services from which each of the Company’s reportable 
segments derives its revenues:

(cid:116) UnitedHealthcare includes the combined results
of operations of UnitedHealthcare Employer & 
Individual, UnitedHealthcare Medicare & Retirement 
and UnitedHealthcare Community & State because 
they have similar economic characteristics, products

operational processes and operate in a similar 
regulatory environment. These businesses also share 
significant common assets, including a contracted 
network of physicians, health care professionals, 
hospitals and other facilities, information technology 
infrastructure and other resources. UnitedHealthcare 
Employer & Individual offers a comprehensive array 
of consumer-oriented health benefit plans and 
services for large national employers, public sector 
employers, mid-sized employers, small businesses and

management, including our principal executive officer and
principal financial officer, as appropriate to allow timely 
decisions regarding required disclosure.

In connection with the filing of this Form 10-K,

Financial Officer, the effectiveness of the design and 
operation of our disclosure controls and procedures as of

REPORT OF MANAGEMENT ON INTERNAL CONTROL OVER
FINANCIAL REPORTING AS OF DECEMBER 31, 2011
The Company’s management is responsible for establishing 
and maintaining adequate internal control over financial 
reporting as defined in Rules 13a-15(f) and 15d-15(f) 
under the Securities Exchange Act of 1934. The Company’s 
internal control system is designed to provide reasonable 
assurance to our management and board of directors 
regarding the reliability of financial reporting and the 
preparation of consolidated financial statements for 
external purposes in accordance with generally accepted 
accounting principles. The Company’s internal control 
over financial reporting includes those policies and 
procedures that (i) pertain to the maintenance of records 
that, in reasonable detail, accurately and fairly reflect the 
transactions and dispositions of the assets of the Company; 
(ii) provide reasonable assurance that transactions are 
recorded as necessary to permit preparation of consolidated 
financial statements in accordance with generally accepted 
accounting principles, and that receipts and expenditures 
of the Company are being made only in accordance with 
authorizations of management and directors of the 
Company; and (iii) provide reasonable assurance regarding 
prevention or timely detection of unauthorized acquisition, 
use or disposition of the Company’s assets that could have a 
material effect on the consolidated financial statements. 
Because of its inherent limitations, internal control 

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

2011 FORM 10-K

77

of December 31, 2011. In making this assessment, we used 
the criteria set forth by the Committee of Sponsoring 
Organizations of the Treadway Commission (COSO) in 
Internal Control - Integrated Framework. Based on our 
assessment and those criteria, we believe that, as of 
December 31, 2011, the Company maintained effective 
internal control over financial reporting. 

The Company’s independent registered public accounting 

firm has audited the Company’s internal control over 
financial reporting as of December 31, 2011, as stated in the 
Report of Independent Registered Public Accounting Firm, 
appearing under Item 9A, which expresses an unqualified 
opinion on the effectiveness of the Company’s internal 
controls over financial reporting as of December 31, 2011.

material misstatements due to error or fraud may not be 
prevented or detected on a timely basis. Also, projections of
any evaluation of the effectiveness of the internal control 
over financial reporting to future periods are subject to 
the risk that the controls may become inadequate because 
of changes in conditions, or that the degree of compliance
with the policies or procedures may deteriorate. 

In our opinion, the Company maintained, in all material
respects, effective internal control over financial reporting 
as of December 31, 2011, based on the criteria established 
in Internal Control - Integrated Framework issued by the 
Committee of Sponsoring Organizations of the Treadway 
Commission.

We have also audited, in accordance with the standards 
of the Public Company Accounting Oversight Board (United
States), the consolidated financial statements as of and for 
the year ended December 31, 2011 of the Company and our
reports dated February 8, 2012 expressed an unqualified 
opinion on those consolidated financial statements and
financial statement schedule.

UNITEDHEALTH GROUP

REPORT OF INDEPENDENT REGISTERED
PUBLIC ACCOUNTING FIRM
To the Board of Directors and Stockholders of UnitedHealth 
Group Incorporated and Subsidiaries: 

We have audited the internal control over financial 

reporting of UnitedHealth Group Incorporated and
Subsidiaries (the “Company”) as of December 31, 
2011, based on criteria established in Internal Control 
- Integrated Framework issued by the Committee of 
Sponsoring Organizations of the Treadway Commission. 
The Company’s management is responsible for maintaining 
effective internal control over financial reporting and for 
its assessment of the effectiveness of internal control over 
financial reporting, included in the accompanying Report of
Management on Internal Control Over Financial Reporting
as of December 31, 2011. Our responsibility is to express an 
opinion on the Company’s internal control over financial
reporting based on our audit. 

We conducted our audit in accordance with the standards

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

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

Because of the inherent limitations of internal control 

over financial reporting, including the possibility of 
collusion or improper management override of controls,
