21. Reconciliation of Additional Disclosures For the quarter ended March 31, 2004 The Operating Cash Flow amounts in the tables presented above are not determined in accordance with accounting principles generally accepted in the United States of America ("U.S. GAAP"). Management uses Operating Cash Flow to evaluate the operating performance of its business, and it is a measure of performance used by some investors, security analysts and others to make informed investment decisions. Operating Cash Flow is used as an analytical indicator of income generated to service debt and fund capital expenditures. In addition, multiples of current or projected Operating Cash Flow are used to estimate current or prospective enterprise value. Operating Cash Flow does not give effect to cash used for debt service requirements, and thus does not reflect funds available for investment or other discretionary uses. Operating Cash Flow as presented herein may not be comparable to similarly titled measures reported by other companies.
