A flow chart is needed to trace the numerous facilities purchased or launched by the A. P. Green Company and the mergers made with other businesses during its years of operation. In the U.S. alone, twelve states had Green manufacturing units in the 1970s, all of which helped meet the growing demand for specialty products. The company first established an international presence by acquiring a plant in Canada in the early 1930s. Another facility in Argentina was added a few years later. By the 1970s, the A. P. Green Company owned or held equity positions in companies in over fifteen countries.
