Context

• These transactions appear linked to RSU vesting and associated dividend equivalents being converted into shares; the withholding was used to cover tax liability rather than an open-market sale. Withholding/surrender of shares to cover taxes is a routine administrative step and does not necessarily indicate a buy/sell trading decision by the insider.
• Transaction codes: A = award/grant, M = exercise/conversion of a derivative, F = tax withholding/disposition.
