Share counts are split-adjusted. Time held counts consecutive quarters ending with the latest filing; more than ten years shows as ">10 Years".

13F data shows quarter-end positions, is delayed by up to 45 days and covers only long positions in US-listed securities; short positions, most derivatives and non-US assets are not reported.
