Context

• Code A indicates an equity award (restricted stock/RSUs); code F indicates shares were withheld to satisfy tax withholding—this is a routine administrative step and not an open-market sale.
• For retail investors, awards signal company compensation decisions rather than direct buying or selling by the executive; the withholding reduces the number of shares actually delivered to the insider.
