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.
