Context

• This was an option exercise with shares withheld/sold to cover tax obligations (a common, routine post-exercise tax settlement), not an open-market purchase or a discretionary sale for investment reasons. The derivative entry reflects conversion of options into common shares; the F code indicates shares were used to satisfy tax withholding rather than a separate planned market sale.
