SEC Information. Certain Information provided on this web site has been filed with the Securities and Exchange Commission ("SEC") (such Information being referred to as "SEC Information"). Pioneer does not assume any duty of disclosure beyond that which is imposed by law and expressly disclaims any duty to update any Information contained in the SEC Information. The SEC Information should be read in conjunction with Pioneer’s periodic reports filed with the SEC, including the disclosures therein of certain factors which may affect the registrant’s future performance. Individual statements appearing in the SEC Information are intended to be read in conjunction with and in the context of the complete SEC Information documents in which they appear, rather than as stand-alone statements.  Cautionary Note to U.S. Investors – The SEC prohibits oil and gas companies, in their filings with the SEC, from disclosing estimates of oil or gas resources other than “reserves,” as that term is defined by the SEC. From time to time, Pioneer provides estimates of quantities of oil and gas using certain terms, such as “expected,” “resource,” “resource potential,” “recoverable resource potential,” “EUR,” “oil in place,” or other descriptions of volumes of reserves, which terms include quantities of oil and gas that may not meet the SEC’s definitions of proved, probable and possible reserves, and which the SEC's guidelines strictly prohibit Pioneer from including in filings with the SEC. These estimates are by their nature more speculative than estimates of proved reserves and accordingly are subject to substantially greater risk of being recovered by Pioneer. Readers are urged to consider closely the disclosures in Pioneer’s periodic filings with the SEC. Such filings are available from Pioneer at 5205 N. O'Connor Blvd., Suite 200, Irving, Texas 75039, Attention Investor Relations, and at the “Investors” section of this website. These filings also can be obtained from the SEC by calling 1-800-SEC-0330.
