Forward-looking statements can be identified by such words as “anticipate, ” “believe, ” “plan, ” “assume, ” “could, ” “should, ” “estimate, ” “expect, ” “intend, ” “potential, ” “seek, ” “predict, ” “may, ” “will” or the negative of these terms and similar expressions. All statements contained in this presentation, conference call and discussions that follow, other than statements of historical facts, such as those regarding our growth initiatives, business strategies, operating plans, business outlook, restructuring activities, impacts of recent legislation, and market conditions, are forward-looking statements. These statements are neither promises nor guarantees, but involve known and unknown risks and uncertainties that may cause our actual results to differ materially from any future results expressed or implied by the forward-looking statements. These risks include important factors discussed in the “Risk Factors” section in Part I of our most recent Annual Report on Form 10-K and any subsequently filed Quarterly Reports on Form 10-Q, which are filed with the SEC and available on the investor section of Sealed Air’s website (www.sealedair.com) and on the SEC’s website at www.sec.gov. Any forward-looking statements made by us in this presentation, conference call or discussions that follow are based solely on management’s estimates as of the date of this presentation and conference call or such discussions. While we may elect to update such forward-looking statements, we disclaim any obligation to do so even if subsequent events cause our views to change, except as may be required by applicable law. Non-GAAP Financial Measures In this presentation, we include certain non-GAAP financial measures, including Net Debt, Adjusted Net Earnings and Adjusted EPS , net sales on an "organic" and a “constant dollar” basis, Free Cash Flow, Adjusted EBITDA, Adjusted EBITDA Margin and Adjusted Tax Rate. Management uses non-GAAP financial measures to assess operating and financial performance, set budgets, provide guidance and compare with peers’ performance. We believe such non-GAAP financial measures are useful to investors. Non-GAAP financial measures should not be considered in isolation from or as a substitute for GAAP information. See the appendix of this presentation for reconciliations of non-GAAP financial measures to their most directly comparable GAAP financial measures. Information reconciling forward-looking non-GAAP financial measures to their most directly comparable GAAP financial measures is not presented because it is not available without unreasonable effort. The reconciling information that is not available includes forward-looking ranges of certain special items with high variability, complexity and low visibility. We are unable to address the probable significance of such unavailable information, which could have a potential significant impact on our future GAAP financial results. Values in this presentation are approximate due to rounding. Additionally, the individual components of bridges or the individual quarterly components presented in the current or prior quarter earnings presentation may not sum to the full y ear amount due to rounding.
