Investor Warren Buffett greets shareholders while touring the exhibit floor prior to holding the Berkshire Hathaway shareholders meeting, in Omaha, Neb., Saturday, May 4, 2013. Tens of thousands attend Berkshire Hathaway shareholder meeting to hear Warren Buffett and Charlie Munger answer questions for more than six hours. No other annual meeting can rival Berkshire's, which is known for its size, the straight talk Buffett and Munger offer and the sales records shareholders set while buying Berkshire products.
