Our acquisition of control of Brasil Telecom could make it difficult for you to evaluate our future prospects.
Because our acquisition of control of Brasil Telecom was consummated in January 2009, the historical financial information included in this annual report with respect to our company does not include financial information regarding Brasil Telecom. Accordingly, the historical financial information included in this annual report may not reflect what our results of operations and financial condition would have been if this acquisition had occurred prior to December 31, 2008. The challenge inherent in integrating Brasil Telecoms business into ours makes evaluating our future financial prospects difficult. You should consider our potential for future business success and operating profitability in light of the risks, uncertainties, expenses and difficulties typically encountered by recently combined companies.
