NEW YORK (Bloomberg) American International Group Inc, the insurer repaying a US bailout, is getting weaker as it sells assets such as Nan Shan Life Insurance Co, former chief executive officer Maurice (Hank) Greenberg said.“Of course they’re making themselves weaker,” Greenberg, who led AIG for almost four decades until 2005, said yesterday in an interview on Bloomberg Television’s “In Business With Margaret Brennan”.The $2.16 billion sale of Taipei-based Nan Shan wasn’t “a great thing to do”, he said.AIG has disclosed deals to divest more than $50 billion of assets since the government’s September 2008 rescue. CEO Robert Benmosche, 66, AIG’s fourth chief since Greenberg’s departure, has sold life insurance units outside the US and focused on global property-casualty coverage.Greenberg, 85, said that strategy may hurt New York-based AIG when prices for property-casualty insurance decline. “AIG will have a more volatile business going forward,” he said.Mark Herr, a spokesman for AIG, declined to comment.Greenberg’s Starr International Co disclosed on March 19, 2010, that it had agreed to sell as many as 10 million of its 14 million shares of AIG.Starr is the third-largest shareholder of AIG after Fairholme Capital Management LLC and the US government, according to Bloomberg data.AIG agreed to sell a 97.57 percent stake in Nan Shan to investors led by Ruentex Group, according to a statement by Ruentex Industries Ltd. to the Taiwanese stock exchange yesterday.
