Context

• The 16,510-item entry is an equity award (restricted share units) that vests over three years; these are not open-market purchases and confer future stock delivery if/when vested.
• The 2,043-share disposal was for tax withholding related to vesting/dividend treatment of RSUs — a routine administrative transaction rather than a conventional sale indicating a change in investment view.
