Warren Buffett was featured in a marathon live appearance on CNBC's "Squawk Box" on Monday. This is an unofficial transcript of all three hours.» Read More
The filing didn't identify what part of Graham Holdings Berkshire might be interested in buying.
Buffett put his money behind his long-held argument that "experts" don't do better than the stock market as a whole. It's the basis of his argument that the fees "helpers" charge investors usually aren't justified.
In a Fortune piece, long-time Buffett friend Carol Loomis writes that after six years the fund Buffett selected for the wager, the Vanguard 500 Index Fund Admiral Shares, was up 43.8 percent at the end of 2013.

Last month, Warren Buffett and Dan Gilbert, founder of Quicken Loans, said they would pay $1 billion to anyone who could pick the perfect NCAA March Madness bracket, but it appears that Yahoo may have had the idea first.
A Dallas-based sweepstakes company is claiming that it is owed $4.4 million by Yahoo for backing out of a similar contest that would have paid $1 billion for a perfect bracket as well, Fortune reported on Tuesday.
According to a lawsuit filed last week, Yahoo signed a deal with SCA Promotions late last year, but canceled the contest shortly after Gilbert and Buffett announced theirs.
Dow Chemical Chairman and CEO Andrew Liveris told CNBC on Wednesday that Warren Buffett supports his vision for the company.
The Buffett praise comes as activist investor Daniel Loeb is putting pressure on Dow to spin off its lucrative but slow-growing petrochemical unit and focus on specialty materials.
Liveris revealed in a "Squawk Box" interview that he met with Buffett this week, and the Berkshire Hathaway boss said: "'We're an owner and we like being an owner. And frankly, we think you've been running the company for the investors who will stay versus the investors who will leave.'"
A Buffett representative confirmed this exchange.
In 2008, Berkshire Hathaway helped to finance Dow's deal to buy specialty chemical maker Rohm and Haas for over $15 billion in cash. Berkshire contributed an equity investment of $3 billion worth of convertible preferred securities.
Liveris said he and Buffett are working together "on the best way to do those preferreds, [which] is to let them earn themselves out. He's in the money. He's now an equity investor. ... When it gets to $53.70, they will disappear."
If you think you can be a great investor, you'd better enjoy working with one of the principal tools of the trade: the 10-K. Berkshire Hathaway's Warren Buffett has said he loves to curl up with companies' annual reports. When asked how to get smarter, Buffett once held up stacks of paper and said he "read 500 pages like this every day. That's how knowledge builds up, like compound interest."
Indeed, smart fund managers think of 10-K's as puzzles or treasure hunts and relish the chance to dig through even the microscopic footnotes.
Federal regulators have begun to look at Warren Buffett's Berkshire Hathaway to see if its failure would be damaging enough to threaten the country's financial stability, according to a report by Bloomberg.
It quotes "two people with knowledge" of the matter as saying the staff of the U.S. Financial Stability Oversight Council, led by Treasury Secretary Jack Lew, wants to determine if Berkshire is so important to the health of the financial system that it needs special supervision by the Federal Reserve.
In what appears to be a unsurprising transition, Matt Rose will become executive chairman of BNSF Railway and drop his CEO role.
President and Chief Operating Officer Carl Ice, who has been with the Berkshire Hathaway subsidiary for 34 years, will become CEO on Jan. 1, 2014.
Rose's move away from day-to-day duties could increase speculation among Buffett watchers that he is a step closer to becoming Warren Buffett's successor as Berkshire's CEO.
The news release, however, makes it sound like Rose will be at BNSF for years to come.
