Reputation

A Strong Reputation

Our company’s reputation continues to grow. We were named to FORTUNE Magazine's list of “World’s Most Admired Companies” for the fourth consecutive year. We were also ranked as a Platinum “Best Employer for Healthy Lifestyles” by the National Business Group on Health and were included on Corporate Responsibility Magazine’s 11th annual “Best Corporate Citizens” list. We also achieved Cancer Gold Standard accreditation from the CEO Roundtable on Cancer.

A Special Thank You

I would like to thank Rosanne Haggerty for her many contributions since she joined our Board of Directors in 2002. Rosanne is retiring from our Board. We will miss her insights, experience and creativity.

Poised for Performance

Despite a challenging environment in 2010, we exited the year with a stronger business and solid prospects for the future.

We are the leader in our industry, which is positioned to benefit from a number of favorable trends. Our strategy is working. Our 40,000-plus employees remain firmly focused on putting patients first and finding new ways to enhance service, improve health outcomes and drive quality and efficiencies in our operations. They are the reason I have confidence in our future.

Thank you for your continued support.

Take care,
