Forward-looking statements can be identified by the fact that they do not relate strictly tohistorical or current facts or by their nature are uncertain and include statements regarding Mattel's plans for future periods and otherfuture events. The use of words such as "anticipates," "expects," "intends," "plans," "projects," "looks forward," "confident that," "believes," and "targeted," among others, generally identify forward-looking statements. These forward-looking statements are basedon currently available operating, financial, economic, and other information and assumptions, and are subject to a number ofsignificant risks and uncertainties. A variety of factors or combination of factors, many of which are beyond Mattel's control, may cause actual results or outcomes, or the timing of those results or outcomes, to differ materially from those contained in any forward- looking statements.
