Over the course of an investing career that has spanned more than half a century, Warren Buffett has obliterated the S&P 500 and the Dow Jones Industrial Average (DJINDICES:^DJI). Since 1964, the per-share book value of his conglomerate, Berkshire Hathaway (NYSE:BRK-B) has risen by a factor of nearly 7,000 for an annualized return of nearly 20%.

The following presentation asks -- and answers -- seven questions that probe various aspects of that exceptional result. You'll also learn why Berkshire Hathaway isn't worth twice its current market value and why Bank of America (NYSE:BAC) has become Berkshire's fifth largest stock holding, even though the common shares don't show up on its balance sheet.
