Forward-Looking Statements

This Current Report on Form 8-K and the information furnished herein contains “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. Forward-looking statements can be identified by such words as “anticipates,” “believes,” “plan,” “assumes,” “could,” “estimates,” “expects,” “intends,” “may,” “plans to,” “will” and similar expressions. Examples of these forward-looking statements include 2013 financial expectations and assumptions associated with our 2011-2014 Integration & Optimization Program, availability and pricing of raw materials, success of our growth programs, economic conditions, and the success of pricing actions. These statements reflect our beliefs and expectations as to future events and trends affecting our business, our consolidated financial position and our results of operations. A variety of factors may cause actual results to differ materially from these expectations, including general domestic and international economic and political conditions affecting packaging utilization; changes in our raw material and energy costs; credit ratings; competitive conditions and contract terms; currency translation and devaluation effects, including Venezuela; the success of our financial growth, profitability and manufacturing strategies and our cost reduction and productivity efforts; the effects of animal and food-related health issues; pandemics; environmental matters; regulatory actions and legal matters; and the successful integration of Diversey. For more extensive information, see “Risk Factors” and “Cautionary Notice Regarding Forward-Looking Statements,” which appear in our most recent Annual Report on Form 10-K, as filed with the Securities and Exchange Commission, and as revised and updated by our Quarterly Reports on Form 10-Q and Current Reports on Form 8-K. While we may elect to update these forward-looking statements at some point in the future, we specifically disclaim any obligation to do so, whether as a result of new information, future events, or otherwise.
