In this case, the comment was made in the context of response to questions about the Company's ability to eventually participate in new projects, where Mr. José Aníbal noted the outcome of the first semester and exemplified that upon reaching approximately R$ 600 million profit in the first semester, the Company could repeat the same number in the second semester, being notorious that the numbers were mentioned just to give an idea of the size of the Company and not to make projections about its results. Thus, we clarify that the comments made to Agência Estado - Broadcast are based on personal and individual expectations of Mr. José Aníbal and should not be interpreted or understood as projections or growth estimates disclosed by the Company. Finally, CESP would like to emphasize that it has chosen not to disclose projections and estimates regarding its operations and results, in accordance with Article 20 of CVM Instruction 480/09, and neither intends to continue not performing nor to disclose such projections and estimates. With that which we needed to present, we take the opportunity to consign our high ratings of esteem and consideration, remaining available to provide any additional information that may be necessary.
