The article refers to the 31 year history of Con-Way. As you must know, Con-Way in its present form did not exist 31 years ago, the geographically separated subsidiary companies of Con-Way Transportation Services (CWX, CCX, and CEX) did however. By the article referring to Con-Way's "31 year history", it obviously considers the three subsidiary companies to have always been one and the same collectively as present day Con-Way. And ultimately, neither CWX or CCX continued to the present day either. CCX eventually expanded into CEX's original territory and ultimately both CWX and CCX were folded into and became present day Con-Way.
