Context

This was a scheduled award settlement (vested PSUs), not a market sale; withholding of shares for taxes is a routine administrative step and does not necessarily signal insider buying or selling interest.
Derivative/“M” codes here reflect the conversion/settlement of equity awards into common shares. The “F” code denotes shares withheld to cover tax obligations.
