16 Nov 2017 Update regarding Berkshire Hathaway's stake in Bank of America ( Portfolio )

A Dataroma user was kind enough to point out that the discrepancy between the 700 million BAC warrants and the reported 679 million BAC shares at qtr-end, is likely due to 21 million shares of BAC being held by a Berkshire subsidiary, New England Asset Management, which is reported separately. It's not clear why this allocation is not included in Berkshire's 13-F filing. Nevertheless, it now appears that Berkshire did not in fact reduce its BAC stake during the quarter.
