Context
Sales made under Rule 10b5‑1 plans are pre‑scheduled and commonly used by insiders to sell shares without active decision‑making at the time of each trade; such sales are often considered routine and do not, by themselves, indicate the insider’s view of the company. This filing reports only sales (no option exercises, awards, or gifts).
