The company logo of American International Assurance Co Ltd (AIA) is seen on top of the AIA Tower in Hong Kong May 19, 2009. AIG is to speed up plans to list its Asian subsidiary through an IPO that could raise more than $4 billion, as the bailed-out U.S. insurer seeks to raise cash to pay back government loans. The IPO would help AIG repay some of the $180 billion the U.S. government has ploughed into what was once the world's biggest insurer, and allow the profitable Asia life insurance subsidiary AIA, to break from its ailing parent.
