Context

• The sequence (exercise then sale) is commonly seen when vested options are exercised and shares are sold to realize proceeds; the filing indicates the open-market sale was made under a pre-established 10b5-1 plan, which is intended to insulate planned trades from insider timing concerns. The $0.00-per-share derivative entry reflects a conversion/settlement event reported on the Form 4 and does not itself show cash proceeds.
