Context

• Code A indicates a grant/award (e.g., restricted stock or similar). Code F reflects shares withheld to satisfy tax withholding — a routine administrative step that does not necessarily signal a voluntary sale. This is not a purchase by the insider; it’s an award grant with automatic withholding to cover taxes.
