Unaudited Interim Information

UNAUDITED INTERIM INFORMATION

The unaudited interim condensed consolidated financial statements of Atwood Oceanics, Inc. and its subsidiaries as of March 31, 2014, and for the three and six months endedMarch 31, 2014 and 2013, 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. and subsidiaries. The year-end condensed consolidated balance sheet data was derived from the audited financial statements as of September 30, 2013. 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 on Form 10-K for the year ended September 30, 2013. In our opinion, the unaudited interim financial statements reflect all adjustments considered necessary for a fair statement of our financial position, results of operations and cash flows for the periods presented.
