| Amendment Description | We are filing this Amendment (“Amendment”) to our Annual Report on Form 20-F (the “Original Filing”) for the sole purpose of amending Item 15(c) of the Original Filing to include the report of our independent registered public accounting firm on internal control over financial reporting, which was inadvertently omitted in the Original Filing. The corrected information in this Amendment does not affect the Company’s audited financial statements filed with the Original Filing. In addition, pursuant to Rule 12b-15 under the Securities Exchange Act of 1934, as amended, the certifications pursuant to Section 302 and Section 906 of the Sarbanes-Oxley Act of 2002 have been re-executed as of the date of, and are re-filed as part of, this Amendment as Exhibits 12.1, 12.2, 13.1 and 13.2. Paragraph 3 of the certifications pursuant to Section 302 of the Sarbanes-Oxley Act of 2002 has been omitted because no financial statements have been included in this Amendment. This Amendment does not reflect events occurring after the filing of the Original Filing and does not modify or update the disclosure therein in any way except as described above. No other changes have been made to the Original Filing. The filing of this Amendment should not be understood to mean that any statements contained in the Original Filing, as amended by this Amendment, are true or complete as of any date subsequent to the original filing date of the Original Filing. Unless otherwise stated herein, all disclosures referenced as being made “as of the date of this Annual Report” or similar language are speaking as of the date of the Original Filing. | |
