The publicly traded company (NYSE: ACM) said June 15 that Rudd's appointment ends its CEO search process, but the selection sparked board controversy, with three board members voting against the selection, including Peter Feld, the executive from activist investor Starboard, a hedge fund with a 4% stake in AECOM, who was named a director last year and chosen to lead the search.
Feld resigned from the AECOM board in a letter the firm reported in an 8K filing to the Securities and Exchange Commission on June 15 but not announced.
