Large holders · SEC Schedules 13D and 13G
Five percent and over
Anyone who comes to hold more than 5% of a company's voting shares must tell the SEC. A Schedule 13D is filed by a holder who may seek to influence the company; a 13G by one who states it is a passive investor. An amendment updates an earlier filing, and a stake reported as 0% means the holder says it has sold all, or nearly all, of its shares. Every recent 13D and 13G
- JPMORGAN CHASE & CO. 3.9%
- FMR LLC 13.5%
