the Attorney General's office secured nearly $100 million from insurers such as Aetna, UnitedHealth Group, and Anthem Inc. Investigations and lawsuits In 2006, the SEC began investigating the conduct of UnitedHealth Group's management and directors, including Dr. McGuire, as did the Internal Revenue Service and prosecutors in the U.S. attorney's office for the Southern District of New York, who have subpoenaed documents from the company. The investigations came to light after a series of probing stories in The Wall Street Journal in March 2006, discussing the apparent backdating of hundreds of millions of dollars' worth of stock options—in a process called options backdating—by UnitedHealth Group management. The backdating apparently occurred with the knowledge and approval of the directors, according to the Journal. Major shareholders have filed lawsuits accusing former New Jersey governor Thomas Kean and UnitedHealth Group's other directors of failing in their fiduciary duty. Resignation of McGuire On October 15, 2006, it was announced that William W. McGuire would step down immediately as chairman and director of UnitedHealth Group, and step down as CEO on December 1, 2006, due to his involvement in the employee stock options scandal. Simultaneously, it was announced that he would be replaced as CEO by Stephen Hemsley, who has served as president and COO and is a member of the board of directors. McGuire's exit compensation from UnitedHealth, expected to be around $1.1 billion, would be the largest golden parachute in the history of corporate America. McGuire's compensation became controversial again on May 21, 2009, when Elizabeth Edwards, speaking on The Daily Show, used it to support her argument for a public alternative to commercial insurance. Edwards stressed the importance of restoring competition in health insurance markets noting that at one point, "the President of UnitedHealth made so much money, that one of every $700 that was spent in this country on health care went to pay him." Since estimates of McGuire's 2005 compensation range from $59,625,444 to $124.8 million, and the revenue of UnitedHealth Group was then $71 billion, it is therefore possible that Mrs. Edwards may have meant that one of every $700 that was spent on UnitedHealth Group premiums went to pay McGuire. McGuire's settlement with SEC On December 6, 2007, the SEC announced a settlement under which McGuire was to repay $468 million, including a $7 million civil penalty, as a partial settlement of the backdating prosecution. He was also
