AIG CEO Robert Benmosche told CNBC's "Closing Bell" foreign exchange plays a part in the firm's revenue slip.
He urged investors to "keep in mind our second largest market outside the United States is in fact Japan and so we have a tremendous amount of premiums and fees coming out of Japan," he said. "With the pressure on the yen and looking at the exchange for the dollar, our premiums are actually growing on the property casualty side, but you don't see it because of the effects of the dollar."
Last month, the insurer launched a new type of insurance policy designed to cover physical harm and personal damages resulting from hacking incidents.
The company, which was nearly wiped out by its derivative bets during the financial crisis, resumed paying dividends last year after it repaid the $180 billion taxpayer bailout it received in 2008.
Former AIG CEO Maurice "Hank" Greenberg is currently battling fraud charges, brought by New York's attorney general, seeking "ill-gotten gains" from his compensation, Reuters reported.
