Context

• These transactions are vesting of performance share units (awards), not open-market buys or discretionary sales. The withholding of shares for taxes is a routine, administrative step (reported as code F), not a market sale by the insider.
• For retail investors, awards + withholding typically reflect compensation vesting rather than an insider expressing a buy/sell view.
