Context

• Code M indicates conversion/settlement of derivative awards (RSUs/PRSUs) into common shares; code F indicates shares withheld to cover tax withholding — a routine, compensation-related transaction rather than an open-market purchase or sale.
• These award-based transactions are common for executives and do not by themselves indicate a buy or sell decision in the open market.
