On December 21, 2011, the Securities and Exchange Commission (the "SEC") adopted its final rules to implement Section 1503 of the Dodd-Frank Wall Street Reform and Consumer Protection Act (the "Act"), which requires mine operators to disclose certain mine safety. While the mine safety disclosure requirements set forth in Section 1503 of the Act became effective on August 20, 2010, the SEC issued the Final Rules in order to facilitate consistent compliance with the Act's requirements and to codify amendments to Forms 8-K, 10-Q, 10-K, 20-F and 40-F.
