Key Details

- F3: Vesting schedule: one-fourth vested on each of 2/5/19, 4/1/19, 7/1/19 and 10/1/19 (i.e., options were fully vested in 2019).
Context: This was an exercise of previously granted options (not a cashless exercise or immediate sale of the newly issued shares per the record). Exercises convert option interests into shares; the $0 disposition line is an administrative reporting entry showing the option ceased to exist. No indication of a 10% owner transaction or gift; the action is simply an insider exercising vested options.
