This document may contain projections, statements and estimates regarding circumstances or events yet to take place. Those projections and estimates are based largely on current expectations, forecasts on future events and financial tendencies that affect the Company’s businesses. Those estimates are subject to risks, uncertainties and suppositions that include, among others: general economic, political and trade conditions in Brazil and in those markets where the Company does business; expectations on industry trends; the Company’s investment plans; its capacity to develop and deliver products on the dates previously agreed upon, and existing and future governmental regulations. The words “believe”, “may”, “is able”, “will be able”, “intend”, “continue”, “anticipate”, “expect” and other similar terms are supposed to identify potentialities. The Company does not feel compelled to publish updates nor to revise any estimates due to new information, future events or any other facts. In view of the inherent risks and uncertainties, such estimates, events and circumstances may not take place. The actual results can therefore differ substantially from those previously published as Company expectations.
