NEW YORK -- Yum Brands ( YUM) warned Monday that KFC sales in China would be slower because of a government review of its poultry. Yum Brands said that due to the bad publicity associated with the review, it expects same-store sales at KFC in China to fall 6% in the fourth quarter; its previous forecast called for a 4% decline. The company said it expects to post adjusted earnings of $3.24 for the fiscal year, below analysts' views of $3.26 a share. AIG's ( AIG) board is meeting Wednesday to consider whether to join a $25 billion shareholder lawsuit against the government, court records show, The New York Times reported. The lawsuit doesn't argue that government help wasn't needed at the giant insurer during the financial crisis, the Times said. AIG just completed paying back the U.S. government for a $182 billion bailout. The newspaper said that AIG contends that the onerous nature of the rescue -- the taking of what became a 92% 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.
