AIG celebrated record results last week, but the company has been brought back to earth by a new subpoena from the New York attorney general's office and the US Securities and Exchange Commission (SEC).
AIG chairman Hank Greenberg complained last week that an over zealous regulatory environment was strangling the US insurance industry.
Within a week, AIG has announced that it will be cooperating with the regulators over new subpoenas.
Greenberg said today the main focus of Eliot Spitzer's probe still appeared to be one broker relationship at the excess casualty division of AIG's American Home Assurance Co. unit.
Internal investigations of more than 850,000 emails and 30,000 documents had failed to turn up any evidence of bid-rigging, AIG said last week.
