Context RSUs are awards that convert to common shares when they vest (these were granted, not purchased). The share withholding to cover taxes is a common, administrative action (code F) and should not be interpreted the same as an open-market sale. Performance-based RSUs vest based on achievement criteria; the filing notes both time-based and performance-based awards.
