The terms “$” or “dollar” refer to U.S. dollars, and the terms “€” or “Euro” refer to the currency introduced at the start of the third stage of European economic and monetary union pursuant to the treaty establishing the European Community, as amended.

Industry and other data

We obtained the industry, statistical and market data in this Annual Report from our own internal estimates and research as well as from industry and general publications and research, surveys and studies conducted by third parties. All of the market data used in this Annual Report involves a number of assumptions and limitations. While we believe that the information from these industry publications, surveys and studies is reliable, the industry in which we operate is subject to a high degree of uncertainty and risk due to a variety of important factors, including those described in the section titled “ITEM 3. KEY INFORMATION — D. Risk factors.” These and other factors could cause results to differ materially from those expressed in the estimates made by the independent parties and by us.
