The attached presentation contains "forward-looking statements" within the meaning of the federal securities laws, which include any statements that are not historical facts, such as Schlumberger's forecasts or expectations regarding business outlook; growth for Schlumberger as a whole and for each of Oilfield Services and WesternGeco (and for specified services, products or geographic areas within each segment); oil and natural gas demand and production growth; operating and capital expenditures, as well as research & development spending, by Schlumberger and the oil and gas industry; the business strategies of Schlumberger's customers; future results of operations and other factors detailed in Schlumberger's most recent Form 10-K, Form 10-Q and other filings with the SEC. These statements are subject to risks and uncertainties, including, but not limited to, the global economy; changes in exploration and production spending by Schlumberger's customers and changes in the level of oil and natural gas exploration and development; general economic and business conditions in key regions of the world; political and economic uncertainty and socio-political unrest; project and new equipment delays; the ability to hire and train new professionals; exploitation of, and changes in, technology; and other risks and uncertainties described elsewhere in the attached presentation, as well as under "Item 1A. Risk Factors" and elsewhere in Schlumberger's most recent Form 10-K filed with the SEC. If one or more of these risks or uncertainties materialize (or the consequences of such a development changes), or should underlying assumptions prove incorrect, actual outcomes may vary materially from those forecasted or expected. Schlumberger disclaims any intention or obligation to update publicly or revise such statements, whether as a result of new information, future events or otherwise.
