As investors and investor groups, we are writing to express our continued support for Section 1502 of the Dodd-Frank Wall Street Reform and Consumer Protection Act and the U.S. Securities and Exchange Commission's Conflict Minerals Rule. No single law can solve all the underlying problems that are causing conflict in the Democratic Republic of Congo (DRC) region, but since 2010, Section 1502 has demonstrated success in diminishing revenue flows to militia groups. The law has also been a catalyst for positive change in the region's mining sector, a vital step toward a more effective response by U.S. companies to address material risk in their supply chains, and has contributed to responsible economic development in the DRC.
