For example:

n The 35 Aetna Volunteer Councils (AVCs) are composed of hundreds of employees, who develop and deploy local employee volunteers to help improve the quality of life in their communities.

n In August 2005, the Points of Light Foundation honored Aetna’s culture of caring with an award for Excellence in Workplace Volunteering.

n Since 2003, Aetna and its employees have contributed more than $26 million to local communities through matching employees’ charitable donations and grants. Employees also have logged more than 700,000 hours of community service over the past three years.

At Aetna, diversity is a core business value and is an integral part of our culture. Valuing diversity helps to ensure we have an engaged, innovative workforce that is doing the right things for the right reasons.

We recognize the impact and importance of diversity in all aspects of our business. Whether it is providing products and services to meet a wide variety of consumer need, fostering relationship with women and minority business owners and suppliers, or attracting a diverse employee population, we have successfully incorporated an inclusive mindset into all that we do.

n Recognizing diversity as an organizational initiative in increasing our business opportunities and partnerships with multicultural markets, suppliers, consumers and the communities we serve.

Workplace Diversity

Reflecting the changing face of America, Aetna seeks to build a workforce that mirrors the customers we serve. Of approximately 30,000 employees, 75 percent are women and 28 percent are people of color. Women represent 61 percent of management, while people of color represent 14 percent.

RecruitmentWe have a staffing strategy to improve the representation of women and people of color at all levels of the organization. Employees are provided with a number of opportunities to learn more about its impact, including:

n Web-based training that raises employee awareness of diversity.

n Cultural competency training program for Aetna’s health care professionals to increase awareness and improve the way we assist members.

n “Diversity in Action” lecture series to help employees think about diversity in new and different ways.

Our Leadership Development Program initiatives focus on identifying emerging talent among people of color. Our Diverse Discoveries program, for example, provides training for mid-level and senior-level women and people of color at Aetna.

We have received wide recognition related to diversity, for example:

n Best Companies for Diversity, Black Enterprise magazine, 2006

n Top 50 Employers for Minorities, Fortune magazine, 2005

n Top 50 Employers for Women, Fortune magazine, 2005

Achievements:n We purchased more than $250 million

in goods and services from certified women-owned and minority-owned business enterprises.

n Our supplier diversity goal for 2006 is to achieve 10 percent of our controllable spending with minority- and women-owned business throughout the country.

n We built an accessible website for potential suppliers www.aetna.com/diversity/supplers.html.

As part of this business strategy, we have an Emerging Markets team to facilitate the following components:

n Drive incremental business through multicultural relationships.

n Provide consulting services to develop appropriate infrastructure

n Enhance market presence within targeted business communities.

To that end, we are focusing our efforts on better addressing the needs of a multicultural marketplace by supporting community events, educating employers, and working with brokers and providers to support our business objectives.

Even as we focus on delivering value in an ever-changing marketplace, Aetna is committed to improving the overall health care system in America. In recent years, we have sought to shed light on important health care issues facing the nation. Aetna is committed to bringing together different perspectives and competing points of view in order to hasten workable solutions to challenging problems affecting access, quality and the affordability of care.

Our Office of Public Policy analyzes critical health policy issues and works with senior executives to craft solutions-oriented approaches. We were the first national health insurer to advocate an individual coverage requirement as a common-sense solution for solving the problem of the uninsured. We collect racial and ethnic data, on a voluntary basis, in order to target medical management programs to those most in need. Our commitment to identify and advance innovative policy solutions has distinguished us in many areas, including end-of-life care, genetic testing, and consumer-directed care.

Improving America’s health care system is a massive undertaking — it is a challenge that Aetna is addressing through public policy leadership.

Public Policy Leadership

Solving the Problem of the Uninsured Through an Individual Coverage Requirement

Aetna is proud to be the first national health plan to endorse an individual coverage requirement as a viable, common-sense solution to the problem of the uninsured.

Research has shown that the uninsured receive less care, utilize fewer preventive services and often fail to adhere to treatments — all resulting in a less healthy population. In turn, the cost of health insurance for everyone increases.

Aetna supports the concept of an individual coverage requirement, ensuring that all Americans possess a basic level of health insurance. We believe a policy requiring those who can afford health insurance to purchase it, however, must be paired with efforts to help those who cannot. Such an approach is the best way to achieve universal coverage while preserving consumer choice and the employer-based health care system.

We also believe:

n Public subsidies for low-income Americans should take the form of advanceable, refundable tax credits or vouchers to help finance the purchase of private health insurance.

n Any required basic benefits plan should include coverage for preventive care and medically necessary treatments, but not be burdened by excessive and costly mandates.

Overcoming Health Care Disparities

Health care disparities are immensely complex, but our targeted investments are slowly bridging the gap.

Numerous studies have shown that racial and ethnic minorities receive lower quality care than non-minorities.

To meet the needs of an increasingly diverse population, Aetna has taken a multidimensional approach to addressing health care disparities. We have launched a variety of prevention, intervention and education initiatives:

n The voluntary provision of self-identified race, ethnicity and language preference data by our members. As of June 2006, more than 3.6 million members provided this information.

n Culturally appropriate disease management initiatives targeted to members with diabetes.

n Cultural competency training for our employees and clinical staff.

n Aetna’s Moms-to-Babies Maternity Management Program, which helps prevent preterm labor for African American women.

Aetna believes price and quality transparency is vital to accelerating consumerism trends.

Paying for Performance

Aetna is facilitating high-quality, high-value health care through pay-for-performance initiatives.

Preventable medical errors and deaths, inconsistent application of evidence-based treatment protocols, and racial, ethnic and geographical disparities in health care are well documented. Billions of dollars are spent each year on improper treatment and the entire system is strained by the indirect financial and human costs of poor quality care.

Aetna addresses these quality problems by:

n Supporting pay-for-performance initiatives, which represent a fundamental shift in provider compensation from paying for the volume of services rendered to paying for quality, outcomes and care consistent with medical evidence.

n Operating regional pay-for-performance initiatives across the country and developing a second generation of national programs that are clinically important, credible to physicians, transparent to all stakeholders, consistent across health plans, and useful to consumers.

n Encouraging high-quality, high-value care by rewarding health care providers for achieving measures of effectiveness and efficiency.

11

Improving Price and Quality Transparency

Aetna has taken the lead in fostering greater price and quality transparency — an effort that is empowering health care consumers.

Aetna believes price and quality transparency is vital to accelerating consumerism trends. Consumers today need access to extensive health information, from treatment options to costs. Therefore, we:

n Launched an initiative in the greater Cincinnati area that gives our members online access to medical rates.

n Announced in June 2006 the rollout of a new price and quality transparency tool in additional markets.

n Provide clinical information, such as adverse events and hospital re-admit rates, for more than 14,800 specialist physicians.
