Hi, you are experienced with this form, what does this mean ? Thanks, Date of relevant event (dd/mm/yyyy) Interests in 3/1/23 ??

Not sure what you are asking exactly, but the link is to a list of all of the shareholding disclosures for BYD's Hong Kong listed shares (HK:1211), which is the class of shares that Berkshire Hathaway Energy owns. As of January 3rd, 2023, the most recent filing, BHE owned 153,332,500 H-shares of BYD (HK:1211).

A filing is required when the "whole number" of the percentage ownership of this specific class of shares (not the entire company, just the % of H-shares)changes. So the last filing was for a trade on 1/3/2023, when BHE's ownership percentage of this class of shares changed from 14.x% to 13.x%. The "no. of shares bought or sold" column is just the number of shares on that specific trading day - not the number sold since the last filing. That is why the media misreports the amount of stock sold each time they report on a new filing here.

The next filing (if they continue to sell) would be required when BHE's ownership of the H-shares goes from the current 13.xx% to 12.xx%.

If they stopped at a round number of 150 million shares, they will not be required to make a filing, since they won't have changed the "whole number" from 13 to 12.

Hope that makes sense.
