One the country’s largest managed health care companies is being sued for violating the Securities Exchange Act of 1934 by including false and misleading information in proxy statements about its political activity.

The Citizens for Responsibility and Ethics in Washington (CREW), on behalf of Stephen W. Silberstein, a shareholder of Aetna Inc., is bringing the suit against Aetna Inc., Mark T. Bertolini (the company chairman, president and CEO), and members of its Board of Directors, for statements made in proxy statements in 2012 and 2013 that CREW feels fail to comply with Securities and Exchange Commission regulations.

CREW also cited Aetna’s filing for 2011 with the National Association of Insurance Commissioners, which shows Aetna contributed $3.3 million to the American Action Network (AAN), a 501c4 organization, and $4.48 million to the U.S.Chamber of Commerce. Aetna did not disclose the AAN contribution in its 2011 report, and only reported $4 million being given to the Chamber of Commerce.

CREW’s complaint was announced in a press release by the Citizens for Responsibility and Ethics in Washington (CREW).
