"OECD Guidance Step 4. Carry out independent third-party audit of supply chain due diligence at identified points in the supply chain.

We relied on the CFSI to conduct independent third-party audits of smelters and refineries, as we typically do not have a direct relationship with 3TG smelters or refineries and do not perform direct audits of these entities. As a participating member of the CFSI, we worked with other members to develop the audit procedures and protocols, as well as revisions to the CMRT. Throughout the reporting year, Cisco shared information on smelters’ identities with CFSI as part of collaborative efforts to track and investigate smelters that may be supplying the industry. In addition, our Supplier Code of Conduct contains conflict minerals compliance provisions."
