Subject: Ron Olson Stepping Down
"Olson, 83, is a partner at the law firm Munger, Tolles & Olson, and has been a Berkshire director since 1997.

He is leaving Berkshire's 14-member board because of the new age limit in its corporate governance guidelines. All other directors apart from Buffett are 75 or younger.

Olson did not immediately respond to requests for comment.

Buffett is excused from the age limit because he controls 30.3% of Berkshire's voting power, triggering an exception for people who control at least 5%."
