Its legal battle in Chicago federal court is against a long list of firms -- including Liberty Mutual Group, Travelers Insurance Group, Hartford Financial Services Group Inc., Ace INA Holdings Inc. and Sentry Insurance Group -- and it stems from those companies' lawsuit against AIG for what they claim was a history of under-reporting workers' compensation premiums to the National Workers' Compensation Reinsurance Pool.
AIG contends those competitors also engaged in under-reporting premiums and conspired with each other to harm AIG.
"Certain competitors continue to wage wasteful litigation against AIG while refusing to reveal how much they and others may have under-reported workers' compensation premiums," AIG spokesman Mark Herr, said in a statement. "Given this, AIG has no choice but to issue subpoenas to discover this information and has been given permission by the court to do so."
In January, the court gave AIG permission to send individual subpoenas to the involved companies.
The original lawsuit brought against AIG alleged the other companies had been cheated because AIG wasn't reporting its honest share of premiums -- which were directly tied to how much the company would be responsible for in losses paid. The National Council on Compensation Insurance had accused AIG of engaging in massive fraud to underpay market assessments over a period of decades. It also argued unfair exclusion from an earlier AIG agreement with New York state regulators to pay $343 million for alleged underpayment of workers' compensation premium taxes and other related fees and assessments.
