"The Company determined the country of origin of its purchased necessary conflict minerals by conducting supply-chain surveys with suppliers we identified primarily using the Responsible Business Alliance (“RBA”) Conflict Minerals Reporting Template (CMRT) as a guide....We use a third party system to facilitate the collection and tracking of CMRTs." "However, we utilize audits of smelters and refiners through the Responsible Minerals Assurance Process (“RMAP”) developed by the RMI which uses an independent third-party audit to identify smelters and refiners that have systems in place to assure sourcing of only conflict-free materials."
