As a result of the demerger, ordinary shareholders in<strong>Antofagasta</strong> received a special dividend on one share in Andsberg Limited for each share held in <strong>Antofagasta</strong>. Andsberg is an unlisted Jerseyregisteredcompany which has as its principal asset the investment in Quiñenco. The Andsberg shares were redeemable for a limited periodat 22.2 cents per share (US$111 per share prior to the restatement for the 2006 bonus issue) and this value has been used to derive thevalue of the total dividend per share of 29.2 cents (restated) for 2003.(5) The order of presentation of items of the summary UK GAAP cash flow statements for 2003 has been amended to facilitate comparison withthe summary IFRS cash flow statements for 2004, 2005, 2006 and <strong>2007</strong>.(6) Short-term cash investments maturing within three months of acquisition previously disclosed under UK GAAP as “current assetinvestments” are classified under IFRS as “cash equivalents”. Due to these differences in classification, the net increase in cash and cashequivalents under IFRS does not correspond to the net cash outflow in the year under UK GAAP. For the summary UK GAAP cash flowstatement for 2003, net cashflow in the year before movement in term deposits has been computed to provide a more comparable (but notequivalent) measure to net increase in cash and cash equivalents under IFRS.(7) Borrowings under IFRS include amounts due under finance leases and preference shares.(8) Loans under UK GAAP include amounts due under finance leases.FURTHER INFORMATION142<strong>Antofagasta</strong> <strong>plc</strong> <strong>Annual</strong> <strong>Report</strong> and Financial Statements <strong>2007</strong>

El Tesoro and Michilla produce coppercathodes with no by-products.c) Cash costs are a measure of the cost of operational production expressed in terms of cents per pound of payable copper produced. Cash costs are stated net ofby-product credits and include tolling charges for concentrate for Los Pelambres. Cash costs exclude depreciation, financial income and expenses, hedging gains andlosses, exchange gains and losses and corporation tax for all three operations. By-product calculations do not take into account unrealised mark-to-market gains formolybdenum at the beginning or end of each period.d) Water volumes include water transportation of 300,000 m 3 in Q1, 266,000 m 3 in Q2, 348,000 m 3 in Q3 and 343,000 m 3 in Q4, totalling 1,258,000 m 3 for <strong>2007</strong>(2006 – 1,604,000 m 3 ).d) The Q4 <strong>2007</strong> water volumes include 77,000 m 3 of water supplied during the first nine months of <strong>2007</strong> but not originally recorded within those periods.e) The totals in the table may include some small apparent differences as the specific individual figures have not been rounded.<strong>Antofagasta</strong> <strong>plc</strong> <strong>Annual</strong> <strong>Report</strong> and Financial Statements <strong>2007</strong> 143FURTHER INFORMATION
