2 We often discuss expectations regarding our markets, demand for our products and services, and our future performance in our annual and quarterly reports, press releases, and other written and oral statements. Such statements, including statements in this document incorporated by reference that relate to matters that are not historical facts are “forward-looking statements” within the meaning of the safe harbor provisions of Section 27A of the U.S. Securities Act of 1933, as amended (the “Securities Act”) and Section 21E of the U.S. Securities Exchange Act of 1934. These “forward-looking statements” are based on our analysis of currently available competitive, financial and economic data and our operating plans. They are inherently uncertain, and investors must recognize that events and actual results could turn out to be significantly different from our expectations. Factors to consider when evaluating these forward-looking statements include, but are not limited to: fluctuations and volatility in worldwide prices of and demand for natural gas and oil; fluctuations in levels of natural gas and oil exploration and development activities; fluctuations in the demand for our services; competitive and technological changes and other developments in the oil and gas and oilfield services industries; changes in the market value of investments accounted for using the equity method of accounting; our ability to complete, and realize the expected benefits of strategic transactions; the existence of operating risks inherent in the oil and gas and oilfield services industries; the possibility of changes in tax and other laws and regulations; the possibility of political or economic instability, civil disturbance, war or acts of terrorism in any of the countries in which we do business; and general economic conditions, including the capital and credit markets. Our businesses depend, to a large degree, on the level of spending by oil and gas companies for exploration, development and production activities. Therefore, a sustained decrease in the price of natural gas or oil, which could have a material impact on exploration and production activities, could also materially affect our financial position, results of operations and cash flows. The above description of risks and uncertainties is by no means all-inclusive, but is designed to highlight what we believe are important factors to consider. Statements made in this presentation include non-GAAP financial measures. The required reconciliation to the nearest comparable GAAP financial measures is included in the Investor Relations section of our website at http://www.nabors.com. Forward-Looking Statements
