Our portfolio of packaging solutions includes CRYOVAC® brand food packaging, SEALED AIR® brand protective packaging, AUTOBAG® brand automated packaging, BUBBLE WRAP® brand packaging and SEE Touchless AutomationTM solutions.

We have established leading market positions through our differentiated packaging materials; automation, equipment, and services; iconic brands; well-established customer relationships; and global scale and market access. We conduct substantially all of our business through two wholly-owned subsidiaries, Cryovac, LLC and Sealed Air Corporation (US). Throughout this report, when we refer to “Sealed Air,” the “Company,” “we,” “our,” or “us,” we are referring to Sealed Air Corporation and all of our subsidiaries, except where the context indicates otherwise. Basis of Presentation Our Condensed Consolidated Financial Statements include all of the accounts of the Company and our subsidiaries. We have eliminated all significant intercompany transactions and balances in consolidation. In management’s opinion, all adjustments, consisting only of normal recurring accruals, necessary for a fair statement of our Condensed Consolidated Balance Sheet as of September 30, 2021 and our Condensed Consolidated Statements of Operations for the three and nine months ended September 30, 2021 and 2020 have been made. The results set forth in our Condensed Consolidated Statements of Operations for the three and nine months ended September 30, 2021 and in our Condensed Consolidated Statements of Cash Flows for the nine months ended September 30, 2021 are not necessarily indicative of the results to be expected for the full year. The Condensed Consolidated Balance Sheet as of December 31, 2020 was derived from audited financial statements but does not include all disclosures required by U.S. GAAP. Some prior period amounts, including the geographic regions described below, have been reclassified to conform to the current year presentation. These reclassifications, individually and in the aggregate, did not have a material impact on our condensed consolidated financial condition, results of operations or cash flows. All amounts are in millions, except per share amounts, and approximate due to rounding. All amounts are presented in U.S. dollar, unless otherwise specified. Our Condensed Consolidated Financial Statements were prepared in accordance with the interim reporting requirements of the SEC. As permitted under those rules, annual footnotes or other financial information that are normally required by U.S. GAAP have been condensed or omitted. The preparation of Condensed Consolidated Financial Statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts and the disclosure of contingent amounts in our Condensed Consolidated Financial Statements and accompanying notes. Actual results could differ from these estimates. We are responsible for the unaudited Condensed Consolidated Financial Statements and notes included in this report. As these are condensed financial statements, they should be read in conjunction with the audited consolidated financial statements and notes included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2020 (“2020 Form 10-K”) and with the information contained in our other publicly-available filings with the SEC. When we cross reference to a “Note,” we are referring to our “Notes to Condensed Consolidated Financial Statements,” unless the context indicates otherwise. There were no significant changes to our significant accounting policies disclosed in “Note 2 – Summary of Significant Accounting Policies and Recently Issued Accounting Standards” of our Annual Report on Form 10-K for the year ended December 31, 2020, which was filed with the SEC on February 25, 2021. As of January 1, 2021, we consolidated the reporting of the North America and South America geographic regions, which are now collectively presented as Americas within Note 3, “Revenue Recognition, Contracts with Customers” and Note 5, “Segments.” No changes were made to EMEA or APAC. This change has no impact on our prior period consolidated results and is only the aggregation of the previously bifurcated continents. Where applicable, prior periods have been retrospectively adjusted to reflect the new geographic regions. Impact of Inflation and Currency Fluctuation Argentina Economic and political events in Argentina have continued to expose us to heightened levels of foreign currency exchange risk. As of July 1, 2018, Argentina was designated as a highly inflationary economy under U.S. GAAP, and the U.S. dollar replaced the Argentine peso as the functional currency for our subsidiaries in Argentina. All Argentine peso-denominated monetary assets and liabilities were remeasured into U.S. dollars using the current exchange rate available to us. The impact of any changes in the exchange rate are reflected within Other (expense) income, net on the Condensed Consolidated Statements of Operations. The Company recorded $0.9 million and $2.8 million of remeasurement losses for the three and nine months ended September 30, 2021, respectively, and $1.1 million and $3.2 million of remeasurement losses for the three and nine months ended September 30, 2020, respectively.
