NEW YORK, April 8 (UPI) -- Investigators are looking into possibly altered key documents in an alleged deal to enhance American International Group's financial picture.
Documents in the 2000 transaction between A.I.G. and General Re, a unit of Berkshire Hathaway, at the center of a wide-ranging insurance investigation, were reportedly doctored two months after the deal was completed, ultimately bolstering A.I.G. stock.
Signs the paperwork had been altered drew the attention of lawyers for the Berkshire unit this year, when they were examining possibly questionable insurance transactions, the New York Times said Friday. Eventually a new round of subpoenaes at A.I.G. led to the downfall of Maurice Greenberg, its chief executive for nearly four decades.
Greenberg will appear before regulators and law enforcement officials in New York on Tuesday to discuss a series of suspect financial transactions.
Warren E. Buffett, chairman and chief executive of Berkshire Hathaway, will appear on Monday, but as a cooperating witness.
