The highlights of our work to date can be summarized into four categories: Establishing a supply chain standard for conflict minerals; performing a Reasonable Country of Origin Inquiry (RCOI) regarding the potential sources of conflict minerals in our products; surveying our direct suppliers using the CFSI Conflict Mineral Reporting Template to ascertain the smelters or refiners present in the supply chain, and working with those smelters and refiners to gain their engagement in the Conflict Free Smelter Program (CFSP).
