Aetna Establishes Majority Voting Standard for Director Elections; Other Corporate Governance Actions Also Taken.

HARTFORD, Conn. -- Aetna Inc. (NYSE: AET) announced today that its Board of Directors has adopted a majority voting standard for director elections and taken other steps to further enhance its corporate governance.

The board amended the company's corporate governance guidelines to include a provision that any director who receives more "withheld" votes than "for" votes in an uncontested election of directors will be required promptly to submit his or her resignation to the Nominating and Corporate Governance Committee of the board. The guidelines require the Nominating Committee to recommend to the board the action to be taken with respect to the resignation and the board to act within a reasonable period of time. The guidelines also require prompt disclosure to the public of each resignation and board decision.

The board also amended the company's corporate governance guidelines to provide for confidential voting in uncontested solicitations and amended the company's bylaws to provide that the board does not have the right to alter the size of the board beyond a range established by the company's shareholders.

"These actions are further evidence of Aetna's long-standing commitment to being a corporate governance leader," said John W. Rowe, M.D., chairman and CEO. "Many shareholders in corporate America want more say when it comes to electing directors at companies. Our board studied other alternatives, including cumulative voting, and decided that implementing a majority vote standard for director elections most effectively responds to shareholder needs and strengthens our board's accountability to our shareholders. We also believe that the package of enhancements adopted today is consistent with corporate governance best practices."
