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
- FMR LLC 15%
- GLENVIEW CAPITAL MANAGEMENT, LLC 4.8%
- ROTHBERG JONATHAN M 0.3%
- Hood River Capital Management LLC 5.61%
- FMR LLC 11.8%
- BlackRock, Inc. 7.8%
