Context

• The disposition (code F) represents shares surrendered to cover tax withholding — a routine, non-market-sale event (cashless withholding) rather than an open-market sale.
• The award arose from a retainer election (receiving stock instead of cash) and does not by itself indicate a change in sentiment about the company.
