Why it may matter

• The filing reports tax withholding on vested restricted stock units rather than an open-market sale initiated by the insider.
• For derivative transactions, the Form 4 shows the disposition method (tax withholding) rather than an exercise-for-cash or market sale.
• A filing does not show why the insider traded or why the company acted.
