## How to read this page

- **Open-market purchase or sale**: A buy or sell of the company's stock at market price. Grants, option exercises, shares withheld for tax, gifts and employee stock plan purchases are listed separately and not counted.
- **Filing date**: Insiders have two business days to report a trade. Totals and the chart use the filing date, when the trade became public.
- **Counted once**: When several owners (a fund and its partners, say) report the same trade, it's counted once. Corrected filings replace the originals.
