Exhibits 97 i Table of Contents PRESENTATION OF INFORMATION In this annual report on Form 20-F, unless the context otherwise requires, references to “LanChile” are to Lan Chile S.A., the unconsolidated operating entity, and references to “LAN,” “we,” “us” or the “Company” are to LanChile and its consolidated subsidiaries. All references to “Chile” are references to the Republic of Chile. This annual report contains conversions of certain Chilean peso amounts into U.S. dollars at specified rates solely for the convenience of the reader. These conversions should not be construed as representations that the Chilean peso amounts actually represent such U.S. dollar amounts or could be converted into U.S. dollars at the rate indicated. Unless we specify otherwise, all references to “$”, “US$”, “U.S. dollars” or “dollars” are to United States dollars, references to “pesos”, “Chilean pesos” or “Ch$” are to Chilean pesos and references to “UF” are to Unidades de Fomento, a daily indexed Chilean peso-denominated monetary unit that takes into account the effect of the Chilean inflation rate. Unless we indicate otherwise, the U.S. dollar equivalent for information in Chilean pesos is based on the observed exchange rate published by Banco Central de Chile (which we refer to as the Central Bank of Chile) on December 30, 2003, which was Ch$599.42=US$1.00. The observed exchange rate on June 8, 2004 was Ch$644.61=US$1.00. The Federal Reserve Bank of New York does not report a noon buying rate for Chilean pesos. See “Key Information—Exchange Rates” under Item 3. LanChile and the majority of our subsidiaries (including our main cargo subsidiary LanChile Cargo S.A., which we refer to as “LanChile Cargo”) maintain their accounting records and prepare their financial statements in U.S. dollars. Some of our other subsidiaries, however, maintain their accounting records and prepare their financial statements in Chilean pesos. Our consolidated financial statements include the results of these subsidiaries translated into U.S. dollars. Current generally accepted accounting principles in Chile, or Chilean GAAP, require monetary assets and liabilities to be translated at period-end exchange rates, non-monetary assets and liabilities to be translated at historical rates of exchange as of the date of acquisition or incurrence and revenue and expense accounts to be translated at the average monthly exchange rate for the month in which they are recognized. As required by Chilean GAAP, the financial statements of our subsidiaries that report in Chilean pesos are adjusted to reflect changes in the purchasing power of the Chilean peso due to inflation. These changes are based on the consumer price index published by the Chilean National Institute of Statistics. Our consolidated financial statements are prepared in accordance with Chilean GAAP, which differs in certain significant respects from generally accepted accounting principles in the United States, or U.S. GAAP. For a description of certain significant differences between Chilean GAAP and U.S. GAAP as they relate to us, together with a reconciliation of our net income and shareholders’ equity to U.S. GAAP, see Note 24 to our audited consolidated financial statements. We have rounded percentages and certain U.S. dollar and Chilean peso amounts contained in this annual report for ease of presentation. Any discrepancies in any table between totals and the sums of the amounts listed are due to rounding. This annual report contains certain terms that may be unfamiliar to some readers. You can find a glossary of these terms on page 3 of this annual report. FORWARD LOOKING STATEMENTS This annual report contains forward-looking statements. Such statements may include words such as “anticipate,” “estimate,” “expect,” “project,” “intend,” “plan,” “believe” or other similar expressions. Forward-looking statements are statements that are not historical facts, including statements about our beliefs and expectations. These statements are based on current plans, estimates and projections, and, therefore, you should not place undue reliance on them. Forward-looking statements involve inherent risks and uncertainties. We caution you that a number of important factors could cause actual results to differ materially from those contained in any forward-looking statement. These factors include, but are not limited to: • our ability to service our debt and fund our working capital requirements; • the maintenance of relationships with customers; 1 Table of Contents • the effects on us from competition; • future demand for passenger and cargo air service in Chile and other countries in Latin America; • the state of the Chilean and world economies and airline industries; • future terrorist incidents or related activities affecting the airline industry; • the relative value of the Chilean peso compared to other currencies; • inflation; • increases in interest rates; and • changes in the regulatory environment in which we operate. Forward-looking statements speak only as of the date they are made, and we undertake no obligation to update publicly any of them, whether in light of new information, future events or otherwise.
