It never ceases to amaze me how lazy these press reports are. This filing showed BHE sold 6.9205 million BYD shares but everyone is too lazy to read the actual filing so they all report 3.23m.
In the filing there are several pairs of identical entries for Berkshire Hathaway and BH Energy. Do both entities separately own the same number of shares? Or is this a quirk of reporting requirements that obliges them to duplicate the filing?
Only BH Energy owns BYD shares. Through a Nevada subsidiary of BH Energy. So technically Berkshire only owns 92% of whatever BYD shares it says BH Energy owns.
