Not all of the included smelters or refiners (“SORs”) may have processed the necessary 3TG contained in Zoetis’ in-scope products, since most of our suppliers reported at a “company level,” meaning that they reported the 3TG contained in all of their products, not just those in the products that they sold us. Some Suppliers also may have reported SORs that were not in Zoetis’ supply chain due to over-inclusiveness in the information received from their suppliers or for other reasons. In addition, the SORs reflected above may not include all of the SORs in Zoetis’ supply chain, since some Suppliers did not identify all of their SORs and because not all Suppliers responded to Zoetis’s inquiries.
