Context

• Transaction codes: M = exercise or conversion of a derivative (e.g., options or conversion of units), A = award/grant, F = payment of exercise price or tax withholding. The 4,600-share disposition is a tax withholding event (not an open-market sale) to satisfy taxes on vested awards/converted shares. The $0.00 reported prices reflect the reporting of awards/conversions rather than a cash purchase price.
