Changes in Registrant's Certifying Accountant ------ --------------------------------------------- Effective March 22, 2002, the Board of Directors of Occidental Petroleum Corporation (the "Company") decided to no longer engage Arthur Andersen LLP ("Arthur Andersen" or "AA") as the Company's independent public accountants and engaged KPMG LLP ("KPMG") to serve as the Company's independent public accountants for the fiscal year 2002, in accordance with the recommendation of the Board's Audit Committee. Arthur Andersen's audit reports on the Company's consolidated financial statements for each of the fiscal years ended December 31, 2001 and 2000 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 Company's two fiscal years ended December 31, 2001 and 2000 and the subsequent interim period preceding the decision to change independent public accountants, there were no disagreements with Arthur Andersen on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure which, if not resolved to AA's satisfaction would have caused them to make reference to the subject matter of the disagreement in connection with the audit reports on the Company's consolidated financial statements for such years, and there were no reportable events as defined in Item 304(a)(1)(v) of Regulation S-K. The Company provided Arthur Andersen with a copy of the foregoing disclosures. Attached as Exhibit 16.1 is a copy of AA's letter, dated March 22, 2002, stating its agreement with such statements. In the years ended December 31, 2001 and 2000 and through the date hereof, the Company did not consult KPMG with respect to 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 Company's consolidated financial statements, or any other matters or reportable events as set forth in Items 304(a)(2)(i) and (ii) of Regulation S-K.
