A New York judge held former American International Group Inc. Chief Executive Maurice "Hank" Greenberg liable for damages on a reinsurance transaction that state Attorney General Andrew Cuomo said helped the insurer hide losses. New York State Supreme Court Justice Charles Ramos also found former Chief Financial Officer Howard Smith liable on the transaction, which involved an entity called Capco Reinsurance Co. It was allegedly used to hide more than $200 million of losses from an auto warranty insurance program.
