Buffett, chairman and chief executive officer of Berkshire Hathaway Inc. since 1970, gets no bonus or stock options, the investment firm said in a regulatory filing Thursday.

Besides his salary, he received $114,250 in 2006 for serving on the boards of companies in which Berkshire has significant stakes. In 2005, his directors' fees were $209,000.

The 76-year-old transformed a failing textile manufacturer into a holding company with dozens of interests, including Rocky Mountain Power and RC Willey in Utah.

Buffett's share of Berkshire's stock, valued at more than $50 billion, makes him the wealthiest man after Microsoft Corp. Chairman Bill Gates.

Berkshire's shareholder equity rose by $16.9 billion in 2006. Much of the gain, he said came from luck - the absence of hurricanes after two years of storms that hurt Berkshire's insurance businesses.

''We believe that $16.9 billion is a record for a one-year gain in net worth - more than has ever been booked by any American business,'' not counting mergers, Buffett wrote in a March 1 letter to shareholders.

Berkshire shares rose 24 percent in 2006, to $109,990, compared with a 14 percent gain for the Standard & Poor's 500 Index.

The compensation committee disregarded the increase, as a matter of policy, in setting Buffett's salary.
