The Securities and Exchange Commission, by a 3-2 vote on Wednesday, approved a long-delayed rule that requires companies to make specialized disclosures about their use of so-called “conflict minerals.”
Section 1502 of the Dodd-Frank Act directed the SEC to adopt a rule requiring corporate disclosures related to the use of certain minerals that are mined in the Democratic Republic of Congo, or adjoining countries, and used to finance the militia groups responsible for ongoing, violent conflict in the region.
