CLARIFICATIONS ON NEWS ABOUT THE ADMINSITRATIVE PROCESS JUDGED BY

THE SUPERIOR CHAMBER OF TAX APPEALS OF THE CARF

TIM S.A. ("TIM" or "Company") (B3: TIMS3; NYSE: TIMB), in accordance with article 157 of Law no. 6,404/1976, with the provisions of CVM Resolution No. 44, informs its shareholders, the market in general and other interested parties, in clarification to journalistic articles about the administrative proceeding judged by the Superior Chamber of Tax Appeals of CARF, the following:

Initially, it is important to inform that the publications are not 100% accurate, which is why we detail below what happened in the trial mentioned in the publications.

In a decision handed down yesterday, by the Superior Chamber of Tax Appeals of CARF, within the scope of the PAF administrative process no. 10480.721765/2011-46, that deals with several subjects, mainly the deductibility of the goodwill amortized by the Company as a result of the acquisitions it has promoted since the privatization process, as well as well as the possibility of using tax losses in situations of corporate restructuring, the Company informs that it had a partial administrative success of around 45% of the total in judgment, with the difference being subject to appeal in court.

The aforementioned publications state that TIM would have "lost" a case worth more than R$1 billion, however, the information does not match the reality of the facts, with the amount that was under discussion in this judgment having an updated value of approximately R$ 700 million.

It is important to clarify that since the beginning of the process in 2011 (initial value of R$ 1.265 billion) the Company has already been successful in obtaining more than 70% of the total amount discussed at the administrative level.

It should also be mentioned that, from an accounting point of view, considering that the discussion on the topic can still be taken to court, there is no additional impact that is not already registered on the Company's balance sheet.

The Company will keep its shareholders and the market in general duly informed about the relevant updates related to this subject, pursuant to CVM Resolution No. 44 and applicable legislation.
