Buffett eyes utilities and overseas acquisitions

Warren Buffett's investment company Berkshire Hathaway Inc. is interested in buying further utility firms in the coming years and seeks to expand abroad, the U.S. billionaire said on Monday.

In May, Buffett's company bought 80 percent of Israeli metal tools maker Iscar Metalworking Cos. for $4 billion. It was Berkshire's first acquisition of a non-U.S.-based firm.
