- For investors tracking insider activity, purchases are typically more informative as positive signals; large sales can be routine when governed by trading plans.
- The filing includes weighted-average price footnotes; the reporting person has committed to provide detailed per-price sale information to the company, shareholders, or the SEC upon request.
