CMR: "OECD Step 4 - Carry out independent third-party audits of supply chain due diligence at identified points in the supply chain ● We joined the RMI in 2013 (member ID: GOOG), and we continue to be a member. ● We relied upon the RMI to validate that companies meet the criteria of smelter and then certify them as conformant via the RMAP. ● We worked with a third party to provide an assessment of smelters not participating in RMI to give Alphabet visibility on all smelters identified in supplier outreach. ● We conducted sustainable supply chain audits with independent third parties on a portion of our suppliers, which included reviewing their conflict minerals programs. ● In 2018 we completed three onsite standard smelter and refiner visits to encourage participation in the RMAP, and to better understand issues smelters face in the compliance process, and management systems used for compliance and in-region due diligence. ● We worked with RMI to provide a third party assessment of all non-audited smelters to be incorporated in the June 2019 RCOI data release to benefit all suppliers and stakeholders in evaluating smelters that have not yet undergone an RMI audit."
