Context
The filing shows both a routine open-market sale and the vesting of performance-based awards on the same date. Vesting of PSUs is an acquisition event (reported as $0 price since they were earned awards); the subsequent sale of some shares is common but the filing does not state the reason for the disposition (e.g., tax withholding, diversification). No late filing or unusual derivatives activity is indicated.
