TABLE OF CONTENTS

        On April 17, 2007, KPMG LLP ("KPMG") was dismissed as the independent registered public accounting firm of the ENSCO Savings Plan, a qualified 401(k) Plan, (the "Plan") and Grant Thornton LLP ("Grant Thornton") was selected as the Plan's independent registered public accounting firm.

        KPMG continues to serve as the independent registered public accounting firm for the Plan's sponsor, ENSCO International Incorporated (the "Company"), having been duly appointed by the Audit Committee of the Board of Directors of the Company, and the replacement of KPMG described above relates only to the Plan. The Company's decision to change the independent auditor for the Plan was approved by the Audit Committee on April 23, 2007.

        The KPMG audit reports on the Plan's financial statements for the fiscal years ended December 31, 2005 and 2004 did not contain an adverse opinion or disclaimer of opinion, nor were they qualified or modified as to uncertainty, audit scope or accounting principles.

        During the years ended December 31, 2005 and 2004 and the subsequent interim period through April 17, 2007, (i) there were no disagreements between the Plan or the Company as its sponsor and KPMG on any matters of accounting principles or practices, financial statement disclosure or auditing scope or procedure, which, if not resolved to the satisfaction of KPMG, would have caused KPMG to make reference in their opinions to the subject matter of the disagreement, and (ii) there were no "reportable events" as that term is defined in Item 304(a)(1)(v) of Regulation S-K between the Plan and KPMG.

        The Plan and the Company have provided KPMG a copy of the foregoing statements and requested a letter from KPMG to the Securities and Exchange Commission stating whether or not KPMG agrees with the above statements. A copy of that letter, dated April 23, 2007, is filed as Exhibit 16.1 to this Form 8-K.

        During the years ended December 31, 2005 and 2004 and the subsequent interim period through April 17, 2007, neither the Plan, and the Company as the Plan's sponsor nor anyone acting on behalf of the Plan or the Company consulted Grant Thornton regarding the application of accounting principles to a specified transaction, either completed or proposed, or the type of audit opinion that might be rendered on the Plan's financial statements.
