Yeah that was his performance fee when he was managing money through the Buffet partnerships. Now he takes 0 and 0 as Chairman and CEO of Berkshire Hathaway. His compensation is primordially in the appreciation of his (substantial) share of the company.
Considering the amount shares he owns, I'd rather be the Chairman and CEO of Berkshire than running a hedge fund. In addition, the float from the insurance companies under his umbrella is more than most hedge fund managers will ever manage.
