Unaudited Interim Information

1. UNAUDITED INTERIM INFORMATION

The unaudited interim condensed consolidated financial statements of Atwood Oceanics, Inc. and its subsidiaries as of December 31, 2011, and for the three month periods ended December 31, 2011 and 2010, included herein, have been prepared in accordance with accounting principles generally accepted in the United States of America for interim financial information and with the instructions for Form 10-Q and Article 10 of Regulation S-X. Unless otherwise indicated, references to "we", "us", "our" and the "Company" refer collectively to Atwood Oceanics, Inc., its subsidiaries and affiliates. The year-end condensed consolidated balance sheet data was derived from the audited financial statements as of September 30, 2011. Although these financial statements and related information have been prepared without audit, and certain information and note disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles have been condensed or omitted, we believe that the note disclosures are adequate to make the information not misleading. The interim financial results may not be indicative of results that could be expected for a full fiscal year. It is suggested that these unaudited condensed consolidated financial statements be read in conjunction with the audited consolidated financial statements and the notes thereto included in our Annual Report to Shareholders for the year ended September 30, 2011. In the opinion of the Company's management, the unaudited interim financial statements reflect all adjustments considered necessary for a fair statement of our results of operations, financial position and cash flows as of and for the periods presented.
