Kraft Heinz Co. (NYSE: KHC) was listed as a massive 325,634,818 shares, worth almost $23 billion at the end of September. This was already known to be a much larger stake after having seen the Kraft-Heinz deal close. That stake was listed as being over $23.5 billion all-in on Kraft-Heinz, as of the previously released September 30 balance sheet. Keep in mind that this was listed outside of being in the grouped equities amount previously of $106.1 billion. See more on Kraft Heinz below.
Phillips 66 (NYSE: PSX) was a total of 61.486 million shares. This stake had been classified as an elimination one quarter ago, but that was really because Buffett got the stake classified confidential. The June 30 stake was really about 29.7 million shares for a 5.57% stake, but that was indicated to be even higher in more recent data we had seen.
Precision Castparts Corp. (NYSE: PCP) is also now an immaterial stake as Berkshire Hathaway has made a formal acquisition offer after having raised its stake to 4.2 million shares in March from 2.853 million shares at the end of 2014 (and versus 2.08 million shares previously). That was listed as the same stake, but in reality this is soon to be a wholly owned subsidiary of Berkshire Hathaway.
