Stocks in the news: AIG, HSBC, Apple, ING

AIG (AIG) announced late Wednesday it agreed to settle a long-standing legal battle with the insurance giant's former chairman, Maurice "Hank" Greenberg. The agreement, announced Wednesday, effectively ends years of costly legal battles and barbs between AIG and Greenberg. AIG shares tumbled nearly 5% in pre-market trading.

HSBC Holdings (HBC) tumbled more than 6% ahead of the bell as investors try to figure out its exposure to Dubai's debt, since it is one of the top two lenders in the United Arab Emirates. HSBC has about $15.9 billion in loans to the UAE. Goldman Sachs has estimated in a worst-case scenario HSBC could face a write-down on its commercial and mortgage loans to Dubai of $611 million.
