Berkshire Hathaway and Buffett Make Many Portfolio Changes for 2013

Berkshire Hathaway Inc. (NYSE: BRK-B, BRK-A) and Warren Buffett may have surprised the markets with the $28 billion purchase of H.J. Heinz Company (NYSE: HNZ), but there is another look to consider here. The conglomerate's most recent U.S.-listed equity holdings have been released and investors will want to know that this is as of December 31, 2012.

Portfolio managers Todd Combs and Ted Weschler are getting even more entrenched as far as their ability to add to positions. The new Buffett holdings are below. American Express Co. (NYSE: AXP) was roughly 151.6 million shares, SAME AS last quarter.

Archer Daniels Midland Co. (NYSE: ADM) was listed as a NEW POSITION of 5.95 million shares worth some $163.1 million as of the end of 2012.

Bank of New York Mellon Corp. (NYSE: BK) appears to be the SAME SIZE at over 19.6 million shares, but that is after gains had been reported in prior quarters.

Coca-Cola Co. (NYSE: KO) was more than 400 million shares due to the stock split of 2012, but this is virtually the SAME AS BEFORE.

ConocoPhillips (NYSE: COP) is the SAME AS BEFORE at 24.1 million shares, but this is lower than in prior quarters.
