When Warren Buffett's time ends, and the 99% of his shares have been distributed, who will hold the majority control of the company he built, and will they be able to maintain the original vision?

"Throughout his great career, Warren Buffett has made huge bets – for example, investing billions in Goldman Sachs during the financial meltdown of 2008. But as shareholders gather in Omaha for the Berkshire Hathaway Annual Shareholders meeting on April 30, they ought to be thinking about Buffett’s biggest bet.

"The altruistic capitalist has pledged to donate 99% of his fortune, which is held primarily in Berkshire stock, to philanthropic causes, largely through the Bill & Melinda Gates Foundation. Mr. Buffett’s extraordinary generosity (his Berkshire wealth is estimated to be worth $66.4 billion) will help to improve education, enhance healthcare, and reduce extreme poverty – a huge boon to societies around the globe."--Josh Barron and Rob Lachenauer, Harvard Business Review
