Our adjusted EBITDA is not a U.S. GAAP measure and it is possible that it may not be comparable with indicators with the same name reported by other companies. Adjusted EBITDA should not be considered as a substitute for operational profit or as a better measure of liquidity than operational cash flow, both of which are calculated in accordance with U.S. GAAP. We provide our adjusted EBITDA to give additional information about our capacity to pay debt, carry out investments and cover working capital needs. The comparison between our results of operations for the first half of 2008 and for the first half of 2007 has been affected by the 17.0% increase in the value of the Real against the U.S. dollar in the first half of 2008 as compared to the first half of 2007. 4 | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
