Warren Buffett's company, Berkshire Hathaway has been dragged into Eliot Spitzer's investigations into US insurance commissions, according to reports.
The Securities and Exchange Commission and the New York attorney general have been investigating a deal between a Berkshire unit, General Re, and AIG, that may have artificially bolstered AIG.'s finances.
Spitzer's inquiry led to the recent resignation of Maurice Greenberg who built and ran AIG.
Investigators are looking into other so-called finite insurance deals by Buffett's companies.
Buffett has made no comment on the reports.
