Changes in Port of Rotterdam Authority Supervisory Board

Scheepbouwer, chair of the Supervisory Board since September 2005, is stepping down due to a fundamental difference of opinion with the shareholders (the municipality of Rotterdam and the State) regarding the process for establishing a new remuneration policy for the Port Authority.

Smit decided not to put himself up for re-appointment after a period of four years, due to a busy schedule elsewhere.

Rutger van Slobbe will take over the chairmanship from Scheepbouwer during the meeting of the Supervisory Board on May17, 2011.
