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.
Pre-arranged (10b5-1)
The insider marked the filing as made under a trading plan set up in advance (SEC Rule 10b5-1). The mark covers the whole filing, and an unmarked filing may still be under a plan.
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.
