| Amendment Description | In each of Items 10-14 of our Annual Report on Form 10-K for fiscal year ended December 31, 2021, filed on March 1, 2022 (the “Original 10-K”) with the Securities and Exchange Commission (the “SEC”), we disclosed that information called for by each item would be set forth in our Proxy Statement for the Annual Meeting of Stockholders to be filed with the SEC within 120 days after the end of the fiscal year ended December 31, 2021, and would be incorporated into the Original 10-K by reference from the Proxy Statement. We are filing this Amendment No. 1 on Form 10-K/A (this “Form 10-K/A”) to include the information required by Items 10-14 and not included in the Original 10-K because we have not filed, and will not file, a definitive proxy statement within 120 days after the end of our fiscal year covered by the Original 10-K. In addition, this Form 10-K/A deletes the reference on the cover of the Original 10-K to the incorporation by reference of portions of our proxy statement into Items 10-14 of the Original 10-K. As required by Rule 12b-15 under the Securities Exchange Act of 1934, as amended, this Form 10-K/A amends Item 15 of Part IV of the Original 10-K to include certifications pursuant to Section 302 of the Sarbanes-Oxley Act of 2002. Because no financial statements are contained within this Form 10-K/A, we are not including certifications pursuant to Section 906 of The Sarbanes-Oxley Act of 2002. Except as described above, this Form 10-K/A does not modify or update disclosure in, or exhibits to, the Original 10-K, including certain defined terms used therein. Furthermore, this Form 10-K/A does not change any previously-reported financial results. Information not affected by this Form 10-K/A remains unchanged and reflects the disclosures made at the time the Original 10-K was filed. | ||
