Our management is responsible for maintaining a system of internal control over financial reporting. This system provides our bondholders with reasonable assurance that our transactions are carried out and maintained in accordance with the guidelines established by our management, and that our financial records provide a reliable basis for the preparation of our financial statements. The system of internal control over financial reporting is supported by recurrent audits, the results of which are reported to management throughout the year. In addition, we maintain reliable databases and use modern and efficient systems designed to generate key financial information.
