Context
These are performance stock options — a form of long-term incentive that, upon vesting, give the holder the ability to buy company shares at a predetermined strike price (strike price not disclosed in this summary). This filing documents the certification and upcoming vesting of PSOs; it is not an open-market purchase or sale and does not show proceeds or immediate share disposition.
