(Bloomberg) -- Warren Buffett, who built Berkshire Hathaway Inc.into a conglomerate with a market value of more than $350 billion,said his firm isn’t even close to being a too-big-to-fail risk tothe economy.

Regulators haven’t contacted Berkshire to discuss its status asa possible systemically important financial institution, Buffettsaid Saturday at the company’s annual meeting in Omaha, Neb. TheSIFI tag subjects companies to Federal Reserve oversight that couldinclude tougher capital, leverage and liquidity requirements.

“I do not think that Berkshire Hathaway comes within miles ofqualifying as a SIFI,” said Buffett, the firm’s chairman and chiefexecutive officer. He said SIFIs tend to get at least 85% ofrevenue from financial operations, and “we don’t come remotelyclose to that.”

Berkshire’s operations range from insurers to heavymanufacturers, retailers and one of the biggest U.S. railroads.Buffett was a source of liquidity during the worldwide creditcrisis beginning in 2008, extending billions of dollars tocompanies including Goldman Sachs Group Inc. and General ElectricCo. through preferred investments.

“During the last time of trouble, we were about the only partythat was supplying help to the financial system,” Buffett said. “Wewill always conduct ourselves in a way such that the problems ofothers can’t hurt us.”

Derivatives Risk

Berkshire’s risk tied to derivatives has declined in recentyears as Buffett, 84, exited some contracts and financial marketsimproved. The company’s liabilities tied to equity-index optionsand credit-default swaps plunged to $3.5 billion as of March 31from about $15 billion six years earlier.

American International Group Inc., the largest commercialinsurer in the U.S. and Canada, is among companies designated by aTreasury Department-led panel as a non-bank SIFI. The others areinsurer MetLife Inc., which sued the U.S. to reverse the decision;GE, which plans to exit most lending operations as a way to shedthe tag; and Prudential Financial Inc.

Bank holding companies with more than $50 billion in assets --including Bank of America Corp., JPMorgan Chase & Co., MorganStanley, Goldman Sachs, Wells Fargo & Co. and Citigroup Inc. --are automatically subject to heightened Fed supervision.
