Context
These entries reflect vesting of performance-based options (derivative awards) rather than open-market buying or selling. Vesting is compensation tied to meeting company performance goals and does not necessarily indicate a personal purchase decision or immediate market action. Because the filing reports $0 consideration and no subsequent sale, there is no cashless exercise or sale shown here.
