Context

• These were grant awards (derivative securities), not open-market purchases or sales. Options and RSUs are compensation-based awards that vest over time or on a specified date; they do not by themselves represent immediate cash proceeds unless exercised or settled. The filing does not state a dollar value for the awards in the excerpt; any eventual value will depend on the company’s stock price at vesting/exercise.
