Context

• A tax-withholding disposition (code F) typically means shares were surrendered or withheld to cover taxes from a grant or option exercise; it does not necessarily indicate a change in the insider’s view of the company. Unlike open-market sales, these transactions are administrative and common after vesting or exercise.
