Directors Deferral Plan, which was inadvertently omitted in the Original Filing and to specifically identify those exhibits which are management contracts, compensatory plans or arrangements.This Amendment is an exhibit-only filing. Except as described above, no changes have been made to the Original Filing and this Amendment does not modify, amend, or update in any way any of the financial or other information contained in the Original Filing. This Amendment does not reflect events that may have occurred subsequent to December 7, 2020. Accordingly, this Amendment should be read in conjunction with the Original Filing and the Company’s other filings with the SEC. Pursuant to Rule 12b-15 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), currently dated certifications are filed herewith as exhibits to this Amendment pursuant to Rule 13a-14(a) or 15d-14(a) of the Exchange Act under Item 15 of Part IV hereof. Because no financial statements have been included in this Amendment and this Amendment does not contain any disclosure with respect to Items 307 and 308 of Regulation S-K, paragraphs 3, 4, and 5 of the certifications have been omitted. Similarly, because no financial statements have been included in this Amendment, certifications pursuant to Section 906 of the Sarbanes-Oxley Act of 2002 have been omitted. | ||
