Why it's admired:Berkshire Hathaway remains one of the most admired companies in the Fortune 500, due to the sage leadership of its CEO Warren Buffett. In a poll, Fortune readers voted Buffett the business person of the year for 2011. Buffett suggested that most likely happened because he's been outspoken about his opinion that America's wealthiest citizens should pay a greater percentage of their income in federal taxes than they currently do.
In this year's annual letter to shareholders, Buffett also outlined his thoughts on why investing in stocks still beats investing in gold and bonds. Berkshire has also begun to welcome some tech companies into the fold. Last November, Berkshire purchased shares in Intel, DirecTV and IBM.
