We are filing this Amendment to amend and restate in its entirety Part II, Item 9A of the Original 10-K to provide our management’s report on the Company’s internal control over financial reporting and correct other inadvertent omissions required to be included pursuant to Items 307 and 308 of Regulation S-K. Pursuant to the SEC rules, Part IV, Item 15 has also been amended to contain the currently dated certificates from the Company’s principal executive officer and principal financial officer pursuant to Section 302 of the Sarbanes-Oxley Act of 2002. The certificates of the Company’s principal executive office and principal financial officer are attached to this Amendment as Exhibit 31.3. Except for the changes to Part II, Item 9A and the filing of related certifications added to the list of Exhibits in Part IV, this Amendment makes no changes to the Original 10-K. Unless otherwise stated, this Amendment does not reflect events occurring after the filing of the Original 10-K or modify disclosures affected by subsequent events. Terms used but not otherwise defined in the Amendment have such meaning as ascribed to them in the Original 10-K. | | |
