Since Berkshire Hathaway Inc. ("Berkshire") acquired General Re Corp. ("Gen Re") (Form 13F File #028-04922) in December 1998, reportable 13F securities owned by Gen Re or its subsidiaries have been reported by New England Asset Management Inc. ("NEAM") (Form 13F File #028-05194), a wholly-owned subsidiary of Gen Re. Those filings have been referenced in Berkshire's Forms 13F as Other Included Managers. Beginning with this Form 13F, the holdings of Gen Re will be included in Berkshire's 13F filing. The NEAM Form 13F filings will no longer include Gen Re's holdings but they will continue to include NEAM client holdings where NEAM is acting as an investment manager. Accordingly, this filing includes the following holdings owned by Gen Re that were formerly reported by NEAM. Apple Inc. - 20,424,207 shares Bank Amer Corp - 22,751,400 shares Chevron Corp New - 2,092,000 shares Citigroup Inc - 89,000 shares Diageo PLC - 227,750 shares HP Inc - 16,476,783 shares Markel Corp - 4,050 shares
