Board of directors
Thomas Macejko and Thomas Souleles, both of Madison Dearborn Partners, LLC (Madison Dearborn), have resigned from the board following the governance changes announced yesterday for Magellan Midstream Holdings, L.P.

MMPs board of directors will continue to consist of seven members. Three of these members, John DesBarres, James Montague and George OBrien, will continue to serve as independent members as defined by the rules of the New York Stock Exchange. Don Wellendorf, the partnerships president and chief executive officer, and Patrick Eilers of Madison Dearborn will remain on the board, with two vacancies to be filled over time.
