OMAHA, Nebraska (AP) ? Billionaire investor Warren Buffett?s Berkshire Hathaway Inc. said it received a subpoena from the New York state attorney general?s office demanding information about its re-insurance subsidiary General Re Corp.

The subpoena was delivered on Thursday, eight days after the US Securities and Exchange Commission asked for identical information about the reinsurance business, Berkshire Hathaway said in a statement. Buffett is chairman of Omaha-based Berkshire Hathaway, which said the subpoena seeks documentation and information relating to non-traditional or loss mitigation insurance products from General Re and all its affiliates ? the same information sought by the SEC.

Federal and state regulators have been examining loss mitigation products to see whether insurance companies sold products that may not really be insurance, but instead may be aimed at helping companies smooth out earnings.

?Berkshire Hathaway and General Re will cooperate fully,? the release said.
