Dodd-Frank Material Disclosure Improvement Act This bill eliminates disclosure requirements applicable to issuers of securities. Specifically, it eliminates requirements to disclose the ratio of an issuer's median employee pay to its Chief Executive Officer pay; the use of conflict minerals originating in the Democratic Republic of the Congo by the issuer; health and safety information of mines operated by the issuer; and payments by an oil, natural gas, or mineral extractor to a foreign government or to the federal government.
