Amendment Description	The Registrant is filing this Amendment No. 1 on Form 10-K/A (the “Amendment”) to its Annual Report on Form 10-K for the fiscal year ended September 28, 2019 (the “Original Form 10-K”) solely in order to correct the reference to and hyperlink for Exhibit 10.14 and to provide more detailed descriptions of certain other exhibits. Except as set forth in this Amendment, no other changes have been made to the Original Form 10-K. Unless expressly stated, this Amendment does not reflect events occurring after the filing of the Original Form 10-K and does not modify or update in any way the disclosures contained in the Original Form 10-K, which speak as of the date of the Original Form 10-K. Accordingly, this Amendment should be read in conjunction with the Original Form 10-K and the Company’s other filings with the Securities and Exchange Commission subsequent to the filing of the Original Form 10-K. Pursuant to Rule 12b-15 under the Securities Exchange Act of 1934, as amended, this Amendment contains new certifications pursuant to Section 302 of the Sarbanes-Oxley Act of 2002, which are attached hereto. Since financial statements are not included in this Amendment and this Amendment does not contain or amend any disclosure with respect to Items 307 and 308 of Regulation S-K, paragraphs 3, 4, and 5 of the certifications have been omitted.
