- 10b5-1 trading plan:
- Unchecked
The filer left the 10b5-1 checkbox unchecked. This is not proof that every trade was unplanned.
A 10b5-1 plan sets trading instructions in advance, so trades follow those instructions instead of a new decision at the time of each trade. The checkbox applies to the filing as a whole and does not identify every covered trade; see the footnotes for details. It reflects the filer's disclosure, not SEC approval of the plan. SEC Form 4 instructions.
