Part I

Item 1.  Business

We are one of the nation’s leading diversified health care benefits companies, serving approximately 36.1 million people with information and resources to help them make better informed decisions about their health care.  We offer a broad range of traditional and consumer-directed health insurance products and related services, including medical, pharmacy, dental, behavioral health, group life and disability plans, and medical management capabilities and health care management services for Medicaid plans.  Our customers include employer groups, individuals, college students, part-time and hourly workers, health plans, governmental units, government-sponsored plans, labor groups and expatriates.

We are dedicated to helping people achieve health and financial security by providing easy access to safe, cost-effective, quality health care and protecting their finances against health-related risks.  We seek to achieve superior customer satisfaction through innovative products, comprehensive health and related benefits choices, effective service and easy-to-understand information.
 
The health insurance and related benefits industry continues to experience significant change.  During 2009, the federal government became increasingly focused on broad-based health care reform, and both the U.S. House of Representatives and Senate passed extensive health reform measures in November and December of 2009, respectively.  On February 22, 2010, President Obama published an alternative proposal for broad-based health care reform legislation.  If enacted, this proposal, which is similar to the legislation passed by the U.S. Senate, would significantly affect our business and results of operations.  Some of the proposed changes in this legislation include a provision for guaranteed issue of coverage in the individual and small group market with a weak mandate that requires coverage. It would also specify required benefit designs, limit rating and pricing practices and impose minimum requirements for medical benefit ratios, create new ways in which health insurance is distributed (for example, state-based health insurance exchanges), encourage additional competition (including potential incentives for new market entrants) and expand eligibility for Medicaid programs.  In addition, President Obama’s proposal would create a new federal Health Insurance Rate Authority that would significantly increase federal oversight of health plan premium rates and could adversely affect our ability to appropriately increase health plan premiums.  Financing for these reforms was expected to come, in part, from material additional fees and taxes on us and other health insurers and health plans, as well as reductions in certain levels of reimbursement under Medicare. Given recent political developments in Washington, D.C., the fate of this legislation and the nature and extent of any other new health care reform is uncertain, though it is reasonably possible that federal heath care reform in some form could be enacted. We cannot predict whether federal health care reform will be enacted, and if it is, what provisions it will contain or what effect it will have on our business or results of operations, although it could have a material adverse effect.  If enacted, health care reform would most likely require significant rule making, and we will continue to work with health care policy makers to ensure Americans have access to affordable insurance.

At the state level, forty-four states and the District of Columbia will hold a regular legislative session in 2010.  We expect state legislatures to focus on the impact of federal health care reform legislation and state budget deficits in 2010.  Proposals under consideration in U.S. Congress could significantly alter the federal structure that shapes the state regulation of health insurance.  While the federal debate is ongoing and the outcome uncertain, if federal health care reform legislation is enacted, states may be required to significantly amend numerous existing statutes and regulations.   Independent of federal efforts, we expect many states to consider legislation to, among other things, extend coverage to the uninsured through health insurance exchanges, increase the limiting age for dependent eligibility, restrict health plan rescission of individual coverage, increase mandatory medical benefit ratios, implement rating reforms and enact an autism benefit mandate.  We cannot predict whether health care reform will be enacted at the state level, and if it is, what provisions it will contain in any state or what effect it will have on our business or results of operations.

In addition, employers, consumers and state governments continue to increase their focus on health care costs and providing health insurance to the uninsured; and they continue to drive changes in the structure of health insurance and related benefits products and services.  Product features continue to evolve that are directed at containing rising health care costs, addressing affordability problems, enhancing access to quality health care services and
Page 1
giving members greater control and responsibility in directing their benefit dollars.  For employer-based health coverage, employers are continuing to require covered employee members to assume a greater portion of the cost of their health care and/or coverage.  These economic factors and greater consumer awareness are leading to increased popularity of products that offer flexibility in design features such as deductibles and co-payments, health savings accounts, consumer access to a broader network of health care providers and quality-based physician networks.  The industry is also subject to other forces including adverse economic conditions in the U.S. and abroad, federal and state legislative and regulatory reforms, advances in pharmaceutical and medical technology, and industry consolidation.  All of these factors can affect the competitiveness of product and service offerings, the range of industry competitors and the bases of competition.
 
We believe that these factors will exist for some time and will drive a continuing evolution in the health insurance and related benefits industry.  We place significant emphasis on developing and maintaining our product and service offerings to serve existing and new customer markets and have done so through organic growth and acquisitions. 

Over the last five years, this focus has led to the introduction of new products, such as Aetna OneSM, our suite of integrated products such as disease management and prevention, wellness and health promotion, and health, disability and absence assessments, designed to help improve member health and productivity and lower benefit trend over time; our Personal Health Record, which provides members with online access to personal information to help them make better informed decisions about their health care; Aetna Health Connections,SM our integrated disease management program; and Medicare Part D prescription drug plans and private fee-for-service Medicare plans (“PFFS”).  We continue to develop and enhance our existing products, such as our AexcelSM physician networks, which are comprised of specialist providers who have demonstrated effectiveness in the delivery of care based on measures of clinical performance and efficiency.  We are also continuing to expand our initiative to improve the transparency of our products and pricing by utilizing our Aetna Navigator online tool to give our members access to physician-specific cost, clinical quality and efficiency information in additional select markets.

We continually evaluate acquisitions and other transactions that present strategic growth opportunities.  During 2009, we expanded our behavioral health capabilities by acquiring a leading provider of employee assistance programs to mid-sized and large employers.  More details about this acquisition are included in Note 3 of Notes to Consolidated Financial Statements on page 55 of the Annual Report which is incorporated herein by reference.

Our operations are conducted in three business segments:  Health Care, Group Insurance and Large Case Pensions.  We derive our revenues primarily from insurance premiums, administrative service fees, net investment income and other revenue.  Refer to Management’s Discussion and Analysis of Financial Condition and Results of Operations (“MD&A”) and Note 19 of Notes to Consolidated Financial Statements beginning on pages 2 and 80, respectively, of the Annual Report, which are incorporated herein by reference, regarding revenue, profit and total asset information for each of our business segments.  The following is a description of each of our business segments.

Health Care
Products and Services
Health Care products consist of medical, pharmacy benefits management, dental, behavioral health and vision plans offered on both an insured basis and an employer-funded, or administrative, basis.  Medical products include point of service (“POS”), preferred provider organization (“PPO”), health maintenance organization (“HMO”) and indemnity benefit (“Indemnity”) plans.  Medical products also include health savings accounts (“HSAs”) and Aetna HealthFund®, consumer-directed health plans that combine traditional POS or PPO and/or dental coverage, subject to a deductible, with an accumulating benefit account.  We also offer Medicare and Medicaid products and services and specialty products, such as medical management and data analytics services, medical stop loss insurance, as well as products that provide access to our provider networks in select markets.  We refer to insurance products as “Insured” and administrative products as “ASC.”

Our principal products and services are targeted specifically to large multi-site national, mid-sized and small employers.  We also serve individual insureds, expatriates and, in certain markets, Medicare and Medicaid beneficiaries.  Medicare and Medicaid products and services are categorized separately from our other Health Care products and services, which we refer to as Commercial.

 
Page 2
 

The primary Commercial products we offer are POS, PPO, HMO and Indemnity plans.  We also offer other products and services.  Our other Commercial products and services include:

ActiveHealth Management
Through the use of our patented CareEngine® system, our ActiveHealth Management business provides evidence-based medical management and data analytics products and services to a broad range of customers, including health plans, employers and others.

Behavioral Health
Our behavioral health products provide members who experience mental health illness with integrated behavioral health benefit administration, access to a network of providers and innovative wellness programs.  On November 1, 2009, we acquired Horizon Behavioral Services, LLC (“Horizon”), a leading provider of employee assistance programs to mid-sized and large employers.  Horizon provides customized behavioral health solutions to employees in all 50 states.

Personal Health Record
Our Personal Health Record provides members with online access to personal information, including individual personalized messages and alerts, detailed health history based on available claims data and voluntarily submitted information, and integrated information and resources to help members make informed decisions about their health care.

Pharmacy
We offer pharmacy benefit management and specialty and mail order pharmacy services to our members.  Our pharmacy fulfillment services are delivered by Aetna Specialty Pharmacy (“ASP”) and Aetna Rx Home Delivery®.  ASP compounds and dispenses specialty medications and offers certain support services associated with specialty medications.  Specialty medications are generally injectable or infused medications that may not be readily available at local pharmacies.  Aetna Rx Home Delivery® provides mail order prescription drug services.

Dental
We offer managed dental plans on an Insured and ASC basis.  We are one of the nation’s largest providers of dental coverage, based on membership at December 31, 2009.

Cofinity
Cofinity provides access to a regional health care provider network to other insurance companies, third party administrators, health plans and employers.  It has operations in Michigan, Colorado and other states.

Stop Loss
We offer medical stop loss insurance coverage for certain employers.  Under this product, we assume the costs associated with large individual claims and/or aggregate loss experience within the employer’s plan above a pre-set annual threshold.

International
We offer comprehensive health benefits and health management solutions worldwide through several different arrangements and offerings that include medical, dental, vision, life, disability and emergency assistance to expatriates, local residents and other constituents.  Our health management business collaborates with health care systems, government entities and plan sponsors around the world to design and build locally-applied health management solutions to improve health, quality and cost outcomes.

Other Commercial Products and Services
We offer a variety of other health care coverage products either as supplements to health products or as stand-alone products.  Such products, which may be offered on an Insured or an ASC basis, include indemnity and vision programs.  We also offer, directly or in cooperation with third parties, our Aetna Health ConnectionsSM disease management program which addresses over 35 chronic conditions, including asthma, diabetes, congestive heart failure and lower back pain.

Page 3
 
In addition to Commercial health products, in select markets we also offer HMO, PPO, PFFS and prescription drug coverage for Medicare beneficiaries and participate in Medicaid and subsidized State Children’s Health Insurance Programs (“SCHIP”).  SCHIP are state-subsidized insurance programs that provide benefits for families with uninsured children.  Our Medicare and Medicaid products include:

Medicare
Through annual contracts with the Centers for Medicare & Medicaid Services (“CMS”), we offer HMO and PPO plans for eligible individuals in certain geographic areas through the Medicare Advantage program.  Members typically receive enhanced benefits over standard Medicare fee-for-service coverage, including reduced cost-sharing for preventive care, vision and other services.  We offered these plans in 219 counties in 19 states and Washington, D.C. in 2009 and are expanding to 246 counties in 22 states and Washington, D.C. in 2010.  In anticipation of changes in the PFFS network requirements that will become effective in 2011, we decided to cease offering Medicare Advantage plans in certain geographic areas in 2010.  We sold mainly individual PFFS plans in these geographic areas.

We are a national provider of the Medicare Part D Prescription Drug Program (“PDP”) in all 50 states to both individuals and employer groups.  All Medicare eligible individuals are eligible to participate in this voluntary prescription drug plan.  Members typically receive coverage for certain prescription drugs, usually subject to a deductible, co-insurance and/or co-payment.

We offer PFFS in select markets nationally for employer groups.  When combined with our PDP product, PFFS forms an integrated national fully-insured Medicare product for employers that provides medical and pharmacy benefits.

Medicaid and SCHIP
We offer healthcare management services for eligible Medicaid and SCHIP individuals under multi-year contracts which are subject to annual appropriations.  We offered these services on an Insured basis in five states, ASC basis in four states and targeted medical management services in four states in 2009.

Provider Networks
We contract with physicians, hospitals and other health care providers for services to our customers.  The health care providers who participate in our networks are independent contractors and are neither our employees nor our agents, except for providers who work in our mail-order and specialty pharmacy facilities.

We use a variety of techniques designed to help encourage appropriate utilization of health care resources and maintain affordability of quality coverage.  In addition to contracts with health care providers for negotiated rates of reimbursement, these techniques include the development and implementation of guidelines for the appropriate utilization of health care resources and the provision of data to providers to enable them to improve health care quality.

At December 31, 2009, we had extensive nationwide provider networks of more than 952 thousand participating health care providers, including over 539 thousand primary care and specialist physicians and over five thousand hospitals.

PCPs
We compensate primary care physicians (“PCPs”) participating in our networks on both a fee-for-service and capitated basis, with capitation generally limited to HMO products in certain geographic areas.  In a fee-for-service arrangement, physicians are paid for health care services provided to the member based upon a set fee for the services provided.  Under a capitation arrangement, physicians receive a monthly fixed fee for each member, regardless of the medical services provided to the member.  We continue to eliminate or reduce the use of capitation arrangements in many areas.  The percentage of health care costs related to capitation arrangements was 4.7% for the year ended December 31, 2009 compared to 5.0% and 5.5% for the years ended December 31, 2008 and 2007, respectively.

Specialist Physicians
Specialist physicians participating in our networks are generally reimbursed at contracted rates per visit or per procedure.

Hospitals
We typically enter into contracts with hospitals that provide for per day and/or per case rates, often with fixed rates for ambulatory, surgery and emergency room services.  We also have hospital contracts that provide for reimbursement based on a percentage of the charges billed by the hospital.

Our medical plans generally require notification of elective hospital admissions, and we monitor the length of hospital stays.  Physicians who participate in our networks generally admit their patients in network-based products to participating hospitals using referral procedures that direct the hospital to contact our patient management unit in order to confirm the patient’s membership status and facilitate the patient management process.  This unit also assists members and providers with related activities, including, if necessary, the subsequent transition to the home environment and home care.  Case management assistance for complex cases is provided by a special case unit.

Other Providers
Laboratory, imaging, urgent care and other freestanding health facility providers are generally paid under fee-for-service arrangements, except for certain laboratory services.

Quality Assessment
We seek accreditation for most of our HMO plans from the National Committee for Quality Assurance (“NCQA”), a national organization established to review the quality and medical management systems of health care plans.  Health care plans seeking accreditation must pass a rigorous, comprehensive review and must annually report on their performance.  As of December 31, 2009, approximately 99.9% of our HMO members participated in HMOs that had received accreditation by the NCQA.

Aetna Life Insurance Company (“ALIC”), a wholly-owned subsidiary of Aetna, has received NCQA PPO Full Accreditation through December 11, 2010.  ALIC will undergo its resurvey in September 2010.

We also seek accreditation and certification for other products from NCQA and URAC, another national organization founded to establish standards for the health care industry.  Purchasers and consumers look to URAC’s and NCQA’s accreditation and certification as an indication that a health care organization has the necessary structures and processes to promote high-quality care and preserve patient rights.  In addition, regulators in over 70% of the states recognize NCQA’s accreditation and certification standards.

Our provider selection and credentialing/recredentialing policies and procedures are consistent with NCQA and URAC, as well as state and federal requirements.  In addition, we are certified under the NCQA Credentials Verification Organization (“CVO”) certification program for all certification options through January 29, 2011.  Our URAC CVO accreditation is valid through October 1, 2012.

Our quality assessment programs for contracted providers who participate in our networks begin with the initial review of health care practitioners.  Practitioners’ licenses and education are verified, and their work history is collected by us or in some cases by the practitioner’s affiliated group or organization.  We generally require participating hospitals to be certified by CMS or accredited by the Joint Commission, the American Osteopathic Association, or Det Norske Veritas Healthcare.

We also offer quality and outcome measurement programs, quality improvement programs, and health care data analysis systems to providers and purchasers of health care services.

Principal Markets and Sales
Our medical membership generally is dispersed throughout the United States, although we serve a limited number of members in countries outside the United States.  Refer to Note 19 of Notes to Consolidated Financial Statements, beginning on page 80 of the Annual Report, which is incorporated herein by reference, for additional information on our foreign customers.  We offer a broad range of traditional and consumer-directed health
 
Page 5
insurance products and related services, many of which are available nationwide.  Depending on the product, we market to a range of customers including employer groups, individuals, college students, part-time and hourly workers, health plans, governmental units, government-sponsored plans, labor groups and expatriates.

Additional information on Health Care’s membership is included in the “Membership” section of the MD&A, on page 7 of the Annual Report, which is incorporated herein by reference.

We market both Insured and ASC products and services primarily to employers that sponsor our products (also called “plan sponsors”) for the benefit of their employees and their employees’ dependents.  Frequently, larger employers offer employees a choice among coverage options, from which the employee makes his or her selection during a designated annual open enrollment period.  Typically, employers pay all of the monthly premiums to us and, through payroll deductions, obtain reimbursement from employees for a percentage of the premiums that is determined by each employer.  Some Health Care products are sold directly to employees of employer groups on a fully employee-funded basis.  In some cases, we bill the covered individual directly.  We also sell Insured plans directly to individual consumers in a number of states.

We sell Insured Medicare coverage on an individual basis as well as through employer groups to their retirees.  Medicaid and SCHIP members are enrolled on an individual basis.

Health Care products are sold through our sales personnel, as well as through independent brokers, agents and consultants who assist in the production and servicing of business.  For large plan sponsors, independent consultants and brokers are frequently involved in employer health plan selection decisions and sales.  We pay commissions, fees and other amounts to brokers, agents, consultants and sales representatives who place business with us.  We support our marketing and sales efforts with an advertising program that may include television, radio, billboards and print media, supplemented by market research and direct marketing efforts.

Pricing
For Commercial Insured plans, employer group contracts containing the pricing and other terms of the relationship are generally established in advance of the policy period and typically have a duration of one year.  We use prospective rating methodologies in determining the premium rates charged to the majority of employer groups, and we also use retrospective rating methodologies for some groups.  Premium rates for customers with more than approximately 125 employees generally take into consideration the individual plan sponsor’s historical and anticipated claim experience where permitted by law.  Some states may prohibit the use of one or more of these rating methods for some customers, such as small employer groups, or all customers.

Under prospective rating, a fixed premium rate is determined at the beginning of the policy period.  We typically cannot recover unanticipated increases in health care costs in the current policy period; however, we may consider prior experience for a product in the aggregate or for a specific customer, among other factors, in determining premium rates for future policy periods.  Where required by state laws, premium rates are filed and approved prior to contract inception.  Our future results could be adversely affected if the premium rates we request are not approved or are adjusted downward by state regulators.
 
Page 6

Under retrospective rating, we determine a premium rate at the beginning of the policy period.  After the policy period has ended, the actual claim and cost experience is reviewed.  If the actual claim costs and other expenses are less than expected, we may issue a refund to the plan sponsor based on this favorable experience.  If the experience is unfavorable, we may, in certain instances, recover the resulting deficit through contractual provisions or consider the deficit in setting future premium levels.  Generally, we may not recover the deficit if a plan sponsor elects to terminate coverage.  Retrospective rating may be used for Commercial Insured plans that cover more than approximately 300 lives.

We have Medicare Advantage and PDP contracts with CMS to provide HMO, PPO, PFFS and prescription drug coverage to Medicare beneficiaries in certain geographic areas.  Under these annual contracts, CMS pays us a fixed capitation payment and/or a portion of the premium, both of which are based on membership and adjusted for demographic and health risk factors.  CMS also considers inflation, changes in utilization patterns and average per capita fee-for-service Medicare costs in the calculation of the fixed capitation payment or premium.  Our PDP contracts also provide a risk-sharing arrangement with CMS to limit our exposure to unfavorable expenses or benefit from favorable expenses.  Amounts payable under the Medicare arrangements are subject to annual revision by CMS, and we elect to participate in each Medicare service area or region on an annual basis.  Premiums paid to us for Medicare products are subject to federal government reviews and audits, which can result and have resulted in retroactive and prospective premium adjustments.  In addition to payments received from CMS, most of our Medicare Advantage products and all of our PDP products require a supplemental premium to be paid by the member or sponsoring employer.  In some cases these supplemental premiums are adjusted based on the member’s income and asset levels.  Compared to Commercial products, Medicare contracts generate higher per member per month revenues and medical costs.

Under our Insured Medicaid contracts with states, government agencies pay us fixed monthly rates per member that vary by state, line of business and demographics; and we arrange, pay for and manage health care services provided to Medicaid beneficiaries.  These rates are subject to change by each state, and in some instances, provide for adjustment for health risk factors.  CMS requires these rates to be actuarially sound.  We also receive fees from our customers where we provide services under ASC Medicaid contracts.  Our ASC Medicaid contracts generally are for periods of more than one year, and certain of them contain guarantees with respect to certain medical, financial and operational metrics, as well as certain performance guarantees regarding reduction of the claim expenses incurred under state government contracts.  Under these guarantees, we are financially at risk if the conditions of the arrangements are not met.  Payments to us under each of these Medicaid contracts are subject to the annual appropriation process in the applicable state.

We offer HMO, consumer-directed and dental plans to federal employees under the Federal Employees Health Benefit Program.  Premium rates for those plans are subject to federal government review and audit, which can result and have resulted in retroactive and prospective premium adjustments.

Our ASC plans are generally for a period of one year, but some last up to three years.  Some of our ASC contracts include performance guarantees with respect to certain functions such as customer service response time, claim processing accuracy and claim processing turnaround time, as well as certain performance guarantees that claim expenses to be incurred by plan sponsors will fall within a specified range.  Under these guarantees, we are financially at risk if the conditions of the arrangements are not met, although the maximum amount at risk is typically limited to a percentage of the fees otherwise payable to us by the customer involved.

Competition
The health care industry is highly competitive, primarily due to a large number of competitors, our competitors’ marketing and pricing, and a proliferation of competing products, including new products that are continually being introduced into the market.  New entrants into the marketplace as well as significant consolidation within the industry have contributed to the competitive environment.

We believe that the significant factors that distinguish competing health plans include the perceived overall quality (including accreditation status), quality of service, comprehensiveness of coverage, cost (including both premium and member out-of-pocket costs), product design, financial stability, geographic scope of provider networks, providers available in such networks, and quality of member support and care management programs.  We believe that we are competitive on each of these factors.  Our ability to increase the number of persons

covered by our plans or to increase our revenues is affected by our ability to differentiate ourselves from our competitors on these factors.  In addition, our ability to increase the number of persons enrolled in our Insured products is affected by the desire and ability of employers to self fund their health coverage.  Competition may also affect the availability of services from health care providers, including primary care physicians, specialists and hospitals.
 
In addition to competitive pressures affecting our ability to obtain new customers or retain existing customers, our membership has been and may continue to be affected by reductions in workforce by existing customers due to soft economic conditions, especially in the geographies where our membership is concentrated.

Our Insured products compete with local and regional health care benefits plans, in addition to health care benefits and other plans sponsored by other large commercial health benefit insurance companies and Blue Cross/Blue Shield plans.  Additional competitors include other types of medical and dental provider organizations, various specialty service providers (including pharmacy benefit providers), integrated health care delivery organizations, health information technology companies and, for certain plans, programs sponsored by the federal or state governments.

Our ASC plans compete primarily with other large commercial health benefit insurance companies, Blue Cross/Blue Shield plans and third party administrators.

Factors Affecting Forward-Looking Information
Information regarding certain important factors that may materially affect Health Care business and our statements concerning future events is included in the “Outlook for 2010” and “Forward-Looking Information/Risk Factors” sections of the MD&A, beginning on pages 3 and 31 of the Annual Report, respectively, which are incorporated herein by reference.

Group Insurance
Principal Products
Group Insurance products consist primarily of the following:

·  
Life Insurance Products consist principally of group term life insurance coverage, the amounts of which may be fixed or linked to individual employee wage levels.  We also offer voluntary spouse and dependent term life coverage, and group universal life and accidental death and dismemberment coverage.  We offer life products on an Insured basis.

·  
Disability Insurance Products provide employee income replacement benefits for both short-term and long-term disability.  We also offer disability products with additional case management features.  Similar to Health Care products, we offer disability benefits on both an Insured and employer-funded basis.  We also provide absence management services to employers, including short-term and long-term disability administration and leave management.

·  
Long-Term Care Insurance Products provide benefits to cover the cost of care in private home settings, adult day care, assisted living or nursing facilities.  Long-term care benefits were offered primarily on an Insured basis.  The product was available on both a service reimbursement and disability basis.  We no longer solicit or accept new long-term care customers, and we are working with our customers on an orderly transition of this product to other carriers.

Principal Markets and Sales
We offer our Group Insurance products in 49 states as well as Washington, D.C., Guam, Puerto Rico, the United States Virgin Islands and Canada.  Depending on the product, we market to a range of customers from small employer groups to large, multi-site and/or multi-state employer programs.

We market Group Insurance products and services primarily to employers that sponsor our products for the benefit of their employees and their employees’ dependents.  Frequently, employers offer employees a choice of benefits, from which the employee makes his or her selection during a designated annual open enrollment period.  Typically, employers pay all of the monthly premiums to us and, through payroll deductions, obtain
Page 8
 
reimbursement from employees for a percentage of the premiums that is determined by each employer.  Some Group Insurance products are sold directly to employees of employer groups on a fully employee-funded basis.  In some cases, we bill the covered individual directly.
 
Group Insurance products are sold through our sales personnel, as well as through independent brokers, agents and consultants who assist in the production and servicing of business.  For large plan sponsors, independent consultants and brokers are frequently involved in employer plan selection decisions and sales.  We pay commissions, fees and other amounts to brokers, agents, consultants and sales representatives who place business with us.  We support our marketing and sales efforts with an advertising program that may include television, radio, billboards and print media, supplemented by market research and direct marketing efforts.

Pricing
For Insured Group Insurance plans, employer group contracts containing the pricing and other terms of the relationship are generally established in advance of the policy period.  We use prospective and retrospective rating methodologies to determine the premium rates charged to employer groups.  These are typically offered with rate guarantees that generally range from one to three years.

Under prospective rating, a fixed premium rate is determined at the beginning of the policy period.  We cannot recover unanticipated increases in mortality or morbidity costs in the current policy period; however, we may consider prior experience for a product in the aggregate or for a specific customer, among other factors, in determining premium rates for future policy periods.

Under retrospective rating, we determine a premium rate at the beginning of the policy period.  After the policy period has ended, the actual claim and cost experience is reviewed.  If the experience is favorable (i.e., actual claim costs and other expenses are less than expected), we may issue a refund to the plan sponsor.  If the experience is unfavorable, we consider the deficit in setting future premium levels, and in certain instances, we may recover the deficit through contractual provisions such as offsets against refund credits that develop for future policy periods.  However, we may not recover the deficit if a plan sponsor elects to terminate coverage.  Retrospective rating is most often used for Insured employer funded plans that cover more than 3,000 lives and pay more than $500,000 in annual premiums.

Competition
For the group insurance industry, we believe that the significant factors that distinguish competing companies are cost, quality of service, financial strength of the insurer, comprehensiveness of coverage, and product array and design.  We believe we are competitive on each of these factors.  The group life and group disability markets remain highly competitive.

Reinsurance
We currently have several reinsurance agreements with nonaffiliated insurers that relate to both group life and long-term disability products.  Most reinsurance arrangements are established on a case by case basis and a subset of our reinsurance agreements cover closed blocks of business and cancelled cases.  We also have reinsurance that provides a limited degree of catastrophic risk protection for certain of our life products.  We frequently evaluate reinsurance opportunities and refine our reinsurance and risk management strategies on a regular basis.

Large Case Pensions
Principal Products
Large Case Pensions manages a variety of retirement products (including pension and annuity products) primarily for tax-qualified pension plans.  Contracts provide non-guaranteed, experience-rated and guaranteed investment options through general and separate account products.  Large Case Pensions products that use separate accounts provide contract holders with a vehicle for investments under which the contract holders assume the investment risk.  Large Case Pensions earns a management fee on these separate accounts.

In 1993, we discontinued our fully-guaranteed Large Case Pensions products.  Information regarding these products is incorporated herein by reference to Note 20 of Notes to Consolidated Financial Statements beginning on page 82 in the Annual Report.  We do not actively market Large Case Pensions products, but continue to accept deposits from existing customers and manage the run-off of our existing business.

Other Matters

Access to Reports
Our reports to the United States Securities and Exchange Commission (the “SEC”), including our Annual Reports on Form 10-K, Quarterly Reports on Form 10-Q, Current Reports on Form 8-K and amendments to those reports, if any, are available without charge on our website at www.aetna.com as soon as practicable after they are electronically filed with or furnished to the SEC.  The information on our website is not incorporated by reference in this Form 10-K.  Copies of these reports are also available, without charge, from Aetna’s Investor Relations Department, 151 Farmington Avenue, Hartford, CT 06156.

Regulation
Information regarding significant regulations affecting us is included in the “Regulatory Environment” and “Forward-Looking Information/Risk Factors” sections of the MD&A, beginning on pages 22 and 31, respectively, of the Annual Report, which are incorporated herein by reference.

Patents and Trademarks
We own the trademarks Aetna®, We Want You To Know® and CareEngine®, together with the corresponding Aetna design logo.  The patent on our CareEngine® expires in 2021.  We consider our CareEngine® and these trademarks and our other trademarks and trade names important in the operation of our business.  However, our business, including that of each of our individual segments, is not dependent on any individual patent, trademark or trade name.

Ratings
Information regarding our ratings is included in the “Ratings” section of the MD&A, on page 15 of the Annual Report, which is incorporated herein by reference.

Miscellaneous
We had approximately 35,000 employees at December 31, 2009.

 
Page 10
 
The United States federal government is a significant customer of both the Health Care segment and the Company.  Premiums and fees and other revenue paid by the federal government accounted for approximately 22% of the Health Care segment’s revenue and 21% of our consolidated revenue in 2009.  Contracts with CMS for coverage of Medicare-eligible individuals accounted for 80% of our federal government premiums and fees and other revenue, with the balance coming from federal employee-related benefit programs.  No other individual customer, in any of our segments, accounted for 10% or more of our consolidated revenues in 2009.  Our segments are not dependent upon a single customer or a few customers, the loss of which would have a significant effect on the earnings of a segment.  The loss of business from any one, or a few, independent brokers or agents would not have a material adverse effect on our earnings or the earnings of any of our segments.  Refer to Note 19 of Notes to Consolidated Financial Statements, beginning on page 80 of the Annual Report, which is incorporated herein by reference, regarding segment information.

Item 1A.  Risk Factors

The information contained in the “Forward-Looking Information/Risk Factors” section of the MD&A, which begins on page 31 of the Annual Report, is incorporated herein by reference.

Item 1B.  Unresolved Staff Comments

None.
 
Item 2.  Properties

Our principal office is a building complex located at 151 Farmington Avenue, Hartford, Connecticut that is approximately 1.7 million square feet in size.  Our principal office is used by all of our business segments.  We also own or lease other space in the greater Hartford area; Blue Bell, Pennsylvania; and various field locations in the United States and several foreign countries.  Such properties are primarily used by our Health Care segment.  We believe our properties are adequate and suitable for our business as presently conducted.

The foregoing does not include numerous investment properties that we hold in our general and separate accounts.

Item 3.  Legal Proceedings

The information contained under Litigation and Regulatory Proceedings in Note 18 of Notes to Consolidated Financial Statements, which begins on page 78 of the Annual Report, is incorporated herein by reference.

EXECUTIVE OFFICERS OF THE REGISTRANT

Aetna’s Chairman is elected by Aetna’s Board of Directors (the “Board”) and all of Aetna’s other executive officers listed on page 12 are appointed by the Board, generally at its Annual Meeting, and such persons hold office until the next Annual Meeting of the Board or until their successors are elected or appointed.  None of these officers has a family relationship with any other executive officer or Director.  In addition, there exist no arrangements or understandings, other than those with Directors or executive officers acting solely in their capacities as such, pursuant to which these executive officers were appointed.

Report of Independent Registered Public Accounting Firm
 




The Board of Directors and Shareholders
Aetna Inc.

Under the date of February 26, 2010, we reported on the consolidated balance sheets of Aetna Inc. and subsidiaries (the “Company”) as of December 31, 2009 and 2008, and the related consolidated statements of income, shareholders’ equity and cash flows for each of the years in the three-year period ended December 31, 2009, as contained in the Annual Report on Form 10-K for the year ended December 31, 2009.  In connection with our audits of the aforementioned consolidated financial statements, we also audited the related financial statement schedule listed in the accompanying index.  The financial statement schedule is the responsibility of the Company’s management.  Our responsibility is to express an opinion on the financial statement schedule based on our audits.

In our opinion, such financial statement schedule, when considered in relation to the basic consolidated financial statements taken as a whole, presents fairly, in all material respects, the information set forth therein.

As discussed in Notes 2 and 5 to the financial statements, effective April 1, 2009, the Company changed its method of accounting for other-than-temporary impairments of debt securities due to the adoption of new accounting guidance issued by the Financial Accounting Standards Board.
