Electronic Proxy Voting
The Proxy Statement is one of Aetna’s most important public documents. It includes information on Aetna’s Board of Directors and describes the proposals to be voted on at the Annual Meeting of Shareholders, which will be held on Friday, May 21, 2010, at the Atlanta Marriott Marquis Hotel in Atlanta, Georgia. This week, Broadridge Financial Solutions, the distribution agent for the trustee of Aetna’s 401(k) Plan, will e-mail voting instructions to active employees who hold Aetna stock through this plan.

All employees who held Aetna stock through the Aetna 401(k) Plan at the close of business on March 19, 2010, are encouraged to inform themselves of the issues being voted on and to exercise their right to vote by Internet or by telephone. The shares held in the Aetna 401(k) Plan are voted by the trustee of the Aetna 401(k) Plan in proportion to the votes the trustee receives from Aetna shareholders with respect to the shares they own through the Aetna 401(k) Plan. Employees’ individual voting instructions are strictly confidential and are not disclosed to Aetna. Employee shareholders who would like to attend the annual meeting will be asked to provide photo identification (Aetna ID badge) before being admitted.

Annual Report
The theme of our online Annual Report is “Creating Value, Shaping the Future.” The report will highlight how Aetna and its employees create value for customers and members through our disease management programs, innovative products, service and technology. To make maximum use of technology, we are featuring video testimonials from our constituents about how we create value for them.

In addition to the marketing content, the Annual Report will feature the Chairman’s Letter, Financial Highlights, our Board and Management and Awards and Recognitions.

You can view the Annual Report at: www.aetna.com/2009annualreport.
