Context
- This is a routine equity compensation vesting event and tax-related withholding, not a market sale intended to raise cash or signal a change in position. For RSU settlements, it’s common for companies to withhold shares to cover taxes rather than require a cash payment.
- Transaction codes: M = conversion/exercise of a derivative instrument (here, RSU settlement), F = shares withheld to satisfy tax withholding.
