Amendment Description Sealed Air Corporation (the Company) is filing this amendment (this Form 10-Q/A) to our Quarterly Report on Form 10-Q for the quarter ended September 30, 2017 (the Form 10-Q), filed with the U.S. Securities and Exchange Commission on November 9, 2017, solely to correct an error on the cover page. The cover page of the Form 10-Q incorrectly stated that the number of shares of the Company's Common Stock outstanding as of October 31, 2017 was 229,996,518. This incorrect number included both the number of shares of Common Stock outstanding and an additional 49,610,170 shares of Common Stock held in treasury that were issued but not outstanding as of that date. The cover page of this Form 10-Q/A correctly states that the number of shares of outstanding Common Stock of the Company as of October 31, 2017 was 180,386,348. The incorrect number of shares outstanding as of October 31, 2017 was also included in Exhibit 101 to the Form 10-Q containing the Company’s Extensible Business Reporting Language (XBRL) materials for the nine-month period ended September 30, 2017. This Form 10-Q/A also amends Item 6, “Exhibits,” specifically by including Exhibit 101 containing the Company’s XBRL materials for the nine-month period ended September 30, 2017 with the corrected number of shares outstanding as of October 31, 2017. This Form 10-Q/A should be read in conjunction with the Form 10-Q, which continues to speak as of the date of the Form 10-Q. Except as specifically noted above, this Form 10-Q/A does not modify or update disclosures in the Form 10-Q. Accordingly, this Form 10-Q/A does not reflect events occurring after the filing of the Form 10-Q or modify or update any related or other disclosures.
