(...)

Following the agenda, Mr. Benedito Braga handed the floor to the Chief Financial and Investor Relations Officer, Rui de Britto Álvares Affonso, who, together with the Accounting Supervisor,  Marcelo Miyagui, the Controllership Supervisor, Agnaldo Pacheco Sampaio, the Funding and Investor Relations Supervisor, Mario A. de Arruda Sampaio, the Legal Supervisor, Tales José B. Bronzato, and the Institutional Legal Counsel Manager, Elizabeth Melek Tavares, presented item 3 on the agenda “Execution of a Private Transaction Agreement and Other Adjustments between SABESP and EMAE” (time: 60’), based on documents filed in the meeting’s electronic folder (...). The purpose of this transaction is to settle the following litigation between Sabesp and EMAE in an amicable and consensual manner:

(a)   Action Requesting Arbitral Submission (Ação de Instituição de Compromisso Arbitral) – Case no. 0064069-18.2012.8.26.0100, currently being examined by the 5^th Lower Civil Court of the Central Jurisdiction of São Paulo (5ª Vara Cível do Foro Central da Comarca de São Paulo), currently on appeal, commenced by EMAE in order to settle the dispute through arbitration;

(b)  Arbitration Proceedings (Procedimento Arbitral) – Case no. 069/2013, currently being examined by the Arbitration Center of the Amcham (São Paulo Chapter), initiated to request financial compensation for alleged past and future losses in the generation of electricity as a result of the water extraction and compensation for alleged costs already incurred and to be incurred with the operation, maintenance and monitoring of the Guarapiranga Reservoir;

(c)   Lawsuit (Ação Ordinária) – Case no. 1064876-84.2013.8.26.0100, currently being examined by the 6^th Lower Civil Court of the Central Jurisdiction of São Paulo (6ª Vara Cível do Foro Central da Comarca de São Paulo), filed by EMAE to request financial compensation for alleged past and future losses in the generation of electricity as a result of water extraction, and apportionment of the alleged costs already incurred and to be incurred with the operation, maintenance and monitoring of the Billings Reservoir by SABESP;

(d)  Interlocutory Injunction for Displaying Documents (Ação Cautelar de Exibição de Documentos) – Case no. 019598-24.2013.8.26.0053, filed by SABESP against EMAE at the 9^th Public Treasury Trial Court of the Judicial District of São Paulo (9.ª Vara da Fazenda Pública da Comarca de São Paulo), to request the production of documents prior to the Settlement Agreement (Termo de Acordo).

Sabesp believes that the water in these reservoirs has always been public, that it cannot be considered as private and that its use for public supply cannot be indemnified. However, in the recent development of litigation involving the two companies, it is noted that: i) that Sabesp’s arguments in court are not being taken into account in the arbitration proceeding with the American Chamber of Commerce in São Paulo (Amcham); ii) that this proceeding is in the hands of a single arbitrator and an expert appointed by him; iii) that the arbitrator has made it very clear that the arbitration proceeding is limited to calculating the indemnity owed.

The agreement was based on the following premises: i) payments by Sabesp must not exceed the necessary amount to reimburse EMAE for the costs of maintaining and operating the Guarapiranga and Billings reservoirs, in proportion to its water abstraction from the natural flow of each of them; ii) payment should continue to be made as long as Sabesp and EMAE’s concessions remain in force, and for as long as Sabesp continues to withdraw from these reservoirs, subject to the period of prescription of the purpose of the actions; iii) Sabesp shall apply to ARSESP for these expenses to be included in the tariff review now in progress.  The agreement establishes that Sabesp will pay EMAE the amounts established in clause 3.1:

(a)   six million, six hundred and ten thousand reais (R$6,610,000.00) per year, adjusted for inflation as of the date of signature of this agreement using the IPCA or any other index that may replace it, always by the last business day of October every fiscal year, under the following conditions: (i) the first of these annual payments is due by the last business day of October 2017 and (ii) the last payment is due by the last business day of October 2042; and

(b)  Forty-six million, two hundred and seventy thousand reais (R$46,270,000.00), in five annual successive installments, adjusted for inflation using the IPCA or any other index that may replace it, under the following conditions: the first installment, of nine million, two hundred and fifty-four thousand reais (R$9,254,000.00), is payable on April 30, 2017, and the remaining four (4) installments of the same amount are payable every April 30, or the next business day, of the subsequent years.

EMAE announced via a notice to the market that its Board of Directors, at a meeting held on November 9, 2016, approved the transaction with Sabesp, pursuant to the Private Transaction Agreement.

The matter was submitted to discussion and vote and, in accordance with the terms of the Agreement, the Board members unanimously approved the transaction related to the Private Transaction and Other Agreements between Sabesp and EMAE, of October 28, 2016. In accordance with Section 2, item 2.1 of the Agreement, the effectiveness of the transaction is subject to the following conditions precedent, given that it has been approved by EMAE’s Board of Directors: (i) EMAE’s Extraordinary Shareholders’ Meeting; and (ii) full and unconditional approval of its terms by the Brazilian Electricity Regulatory Agency – ANEEL, pursuant to article 3, XIII of Law 9,427/1996 and article 18, I of Resolution 699, of January 26, 2016.
