D'K Ascluilork (nines JANUARY 7. 2013 Rescued by a Bailout, A.I.G. May Sue Its Savior By BEN PROTESS and MICHAEL J. DE LA MERCED Fresh from paying back a $182 billion bailout, the American International Group has been running a nationwide advertising campaign with the tagline "Thank you America." Behind the scenes, the restored insurance company is weighing whether to tell the government agencies that rescued it during the financial crisis: thanks, but you cheated our shareholders. The board of A.I.G. will meet on Wednesday to consider joining a $25 billion shareholder lawsuit against the government, court records show. The lawsuit does not argue that government help was not needed. It contends that the onerous nature of the rescue - the taking of what became a 92 percent stake in the company, the deal's high interest rates and the funneling of billions to the insurer's Wall Street clients - deprived shareholders of tens of billions of dollars and violated the Fifth Amendment, which prohibits the taking of private property for "public use, without just compensation." Maurice R. Greenberg, A.I.G.'s former thief executive, who remains a major investor in the company, filed the lawsuit in 2011 on behalf of fellow shareholders. He has since urged A.I.G. to join the case, a move that could nudge the government into settlement talks. The choice is not a simple one for the insurer. Its board members, most of whom joined after the bailout, owe a duty to shareholders to consider the lawsuit. If the board does not give careful consideration to the case, Mr. Greenberg could challenge its decision to abstain. Should Mr. Greenberg snare a major settlement without A.I.G., the company could face additional lawsuits from other shareholders. Suing the government would not only placate the 87-year-old former chief, but would put A.I.G. in line for a potential payout. Yet such a move would almost certainly be widely seen as an audacious display of ingratitude.
