Statements in this report that contain "forward-looking statements" within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended, include, but are not limited to, statements regarding the current term, start and end dates and comments concerning future contracts and availability and other aspects of the Registrant's drilling rigs. Such statements are inherently subject to a variety of risks and uncertainties that could cause actual results to differ materially from those anticipated or projected. A discussion of the risk factors that could impact these areas and the Registrant's overall business and financial performance can be found in the Registrant's reports and other documents filed with the Securities and Exchange Commission. These factors include, among others, general economic and business conditions, casualty losses, industry fleet capacity, changes in foreign and domestic oil and gas exploration and production activity, competition, changes in foreign, political, social and economic conditions, regulatory initiatives and compliance with governmental regulations, customer preferences and various other matters, many of which are beyond the Registrant's control. Given these concerns, investors and analysts should not place undue reliance on forward-looking statements. Each forward-looking statement speaks only as of the date of the rig status report, and the Registrant undertakes no obligation to publicly update or revise any forward-looking statements. 2 SIGNATURES Pursuant to the requirements of the Securities Exchange Act of 1934, as amended, the Registrant has duly caused this report to be signed on its behalf by the undersigned hereunto duly authorized.
