"The good news is that I feel fine, and I continue to work according to my normal schedule," Benmosche said in a statement. "I remain absolutely committed to my job, to AIG, and to all of our stakeholders."
"Our thoughts and prayers are with Bob and his family at this time," said Robert "Steve" Miller, chairman of the AIG board.
Last week, AIG raised more than $17 billion in the IPO of one of its Asian units. The company is seeking to raise funds to pay back the U.S. taxpayer for the multi-billion dollar rescue package implemented during the financial crisis.
