EXPLANATORY NOTE 

Oi S.A. – In Judicial Reorganization (“Oi”) is filing this Comprehensive Annual Report on Form 20-F for the fiscal years ended 
December 31, 2017 and 2016 (the “Comprehensive Form 20-F”) as part of its efforts to become current in its filing obligations under 
the Securities Exchange Act of 1934, as amended (the “Exchange Act”). As described more fully in “Item 4. Information on the 
Company—Our Recent History and Development—Our Judicial Reorganization Proceedings,” on June 20, 2016, Oi and six of its 
wholly-owned direct or indirect subsidiaries filed a joint voluntary petition for judicial reorganization (recuperação judicial) pursuant to 
the Brazilian Bankruptcy Law with the 7th Corporate Court of the Judicial District of the State Capital of Rio de Janeiro (the “RJ 
Court”). On June 29, 2016, the RJ Court granted the processing of this judicial reorganization. On December 19 and 20, 2017, a general 
creditors meeting (the “GCM”) was held to consider approval of the most recently filed judicial reorganization plan. The GCM 
concluded on December 20, 2017 following the approval of a judicial reorganization plan reflecting amendments to the judicial 
reorganization plan presented at the GCM as negotiated during the course of the GCM (the “RJ Plan”). On January 8, 2018, the RJ 
Court entered an order ratifying and confirming the RJ Plan, according to its terms, but modifying certain provisions of the RJ Plan (the 
“Brazilian Confirmation Order”). The RJ Plan became effective on February 5, 2018 upon the publication of the Brazilian Confirmation 
Order in the Official Gazette of the State of Rio de Janeiro (Diário Oficial do Estado do Rio de Janeiro). 

The completion of the preparation of Oi’s financial statements under U.S. GAAP as of and for the year ended December 31, 2016 

required that Oi determine whether the use of a going concern assumption as a basis for the preparation of those financial statements 
was appropriate, and the effects on the balances of assets, liabilities and on items comprising the statements of income, comprehensive 
income, changes in shareholders’ equity and cash flows if those financial statements were not prepared under this assumption. Oi’s 
management was not able to complete the asset impairment testing required under U.S. GAAP and was unable to do so prior to the 
approval of the RJ Plan on December 20, 2017 as this impairment testing required that Oi’s management complete an enterprise 
valuation of Oi and its consolidated subsidiaries. Given the ongoing negotiations between Oi and its creditors with respect to the terms 
of the RJ Plan, Oi’s management was been unable to determine a set of assumptions that were reasonably reliable upon which to 
prepare an enterprise valuation to support the required impairment testing. 

As a result, Oi was unable to determine whether there would be any need to make adjustments in the balances of non-financial 

assets of Oi and its consolidated subsidiaries as of December 31, 2016, as well as in the items of the statements of income, 
comprehensive income, changes in shareholders’ equity and cash flows for the year then ended, and consequently, Oi’s auditor was 
unable to express an opinion on those financial statements. 

As a result of the approval of the RJ Plan and the subsequent confirmation and ratification of the RJ Plan by the RJ Court, Oi’s 
management has been able to complete an enterprise valuation of Oi and its consolidated subsidiaries, complete the asset impairment 
testing required under U.S. GAAP, and determine the adjustments in the balances of non-financial assets of Oi and its consolidated 
subsidiaries as of December 31, 2016, as well as in the items of the statements of income, comprehensive income, changes in 
shareholders’ equity and cash flows for the year then ended. 

The RJ Proceedings prompted us to perform a detailed analysis on the completeness and the accuracy of the judicial deposits and 

accounting balances of the other assets of the RJ Debtors. As a result, we identified weaknesses in some of our operational and financial 
reporting controls and procedures. For more information with respect to the identified material weaknesses in Oi’s internal control over 
financial reporting and the steps that Oi has undertaken to remediate these material weaknesses, see “Item 15. Controls and 
Procedures.” 

Additionally, we determined the need to restate previously issued financial statements and related disclosures to correct errors. 
Accordingly, we are restating our consolidated financial statements for the year ended December 31, 2015. Restatement adjustments 
attributable to fiscal year 2014 and previous fiscal years are reflected as a net adjustment to retained earnings as of January 1, 2015 

The errors detected and corrected in Oi’s financial statements related to its judicial deposits, its provisions for contingencies, 
intragroup balances, tax credits and estimates of revenue from services rendered and not yet billed to customers, as described in “Item 5. 
Operating and Financial Review and Prospects—Financial Presentation and Accounting Policies—Restatement of 2015 Financial 
Statements” and note 2 of our consolidated financial statements. 

In connection with the presentation of financial information as of December 31, 2015, 2014 and 2013 and for the years ended 
December 31, 2014 and 2013, Oi has restated the financial statements related to those dates and periods to correct the errors included in 
these previously issued financial statements. 

The Comprehensive Form 20-F is Oi’s first annual report filed with the Securities and Exchange Commission (the “SEC”) since 
the filing of its Annual Report on Form 20-F for the fiscal year ended December 31, 2015. Included in this Comprehensive Form 20-F 
are Oi’s audited consolidated financial statements as of and for the years ended December 31, 2017 and 2016, which have not been 
previously filed with the SEC.

PRESENTATION OF FINANCIAL AND OTHER INFORMATION 

All references herein to “real,” “reais” or “R$” are to the Brazilian real, the official currency of Brazil. All references to “U.S. 

dollars,” “dollars” or “US$” are to U.S. dollars. 

On May 10, 2018, the exchange rate for reais into U.S. dollars was R$3.5566 to US$1.00, based on the selling rate as reported by 

the Central Bank of Brazil (Banco Central do Brasil), or the Brazilian Central Bank. The selling rate was R$3.3080 to US$1.00 on 
December 31, 2017, R$3.2591 to US$1.00 on December 31, 2016 and R$3.9048 to US$1.00 on December 31, 2015, in each case, as 
reported by the Brazilian Central Bank. The real/U.S. dollar exchange rate fluctuates widely, and the selling rate on May 10, 2018 may 
not be indicative of future exchange rates. See “Item 3. Key Information—Exchange Rates” for information regarding exchange rates 
for the real since January 1, 2013. 

Solely for the convenience of the reader, we have translated some amounts included in “Item 3. Key Information—Selected 
Financial Information” and in this annual report from reais into U.S. dollars using the selling rate as reported by the Brazilian Central 
Bank on December 31, 2017 of R$3.3080 to US$1.00. These translations should not be considered representations that any such 
amounts have been, could have been or could be converted into U.S. dollars at that or at any other exchange rate. 

Financial Statements 

We maintain our books and records in reais. Our consolidated financial statements as of December 31, 2017 and 2016 and for the 

years ended December 31, 2017, 2016 and 2015 are included in this annual report. 

We have prepared our consolidated financial statements as of December 31, 2017 and 2016 and for the years ended December 31, 
2017, 2016 and 2015 in accordance with United States generally accepted accounting principles, or U.S. GAAP, under the assumption 
that we will continue as a going concern. 

Under U.S. GAAP, our management is required to assess whether there are conditions or events, considered in the aggregate, that 

raise substantial doubt about our ability to continue as a going concern within one year after our financial statements are issued. Our 
management’s assessment of our ability to continue as a going concern is discussed in note 1 to our consolidated financial statements. 
As of December 31, 2017, our management had taken relevant steps in the RJ Process, particularly the preparation, presentation and 
approval of the RJ Plan, which allows our viability and continuity, and the approval of the RJ Plan by our creditors. Since December 31 
2017, our management has been making the necessary efforts to implement and monitor the RJ Plan based on the understanding that our 
financial statements were prepared with a going concern assumption. 

As a result of the RJ Proceedings (which are considered to be similar in all substantive respects to proceedings under Chapter 11 

of the U.S. Bankruptcy Code of 1986, as amended, which we refer to as the U.S. Bankruptcy Code), we have applied Financial 
Accounting Standards Board Accounting Standards Codification 852 “Reorganizations”, or ASC 852, in preparing our consolidated 
financial statements. ASC 852 requires that financial statements separately disclose and distinguish transactions and events that are 
directly associated with our reorganization from transactions and events that are associated with the ongoing operations of our business. 
Accordingly, expenses, gains, losses and provisions for losses that are realized or incurred in the RJ Proceedings have been recorded 
under the classification “Restructuring expenses” in our consolidated statements of operations. In addition, our prepetition obligations 
that may be impacted by the RJ Proceedings based on our assessment of these obligations following the guidance of ASC 852 have 
been classified on our balance sheet as “Liabilities subject to compromise.” Prepetition liabilities subject to compromise are required to 
be reported at the amount allowed as a claim by the RJ Court, regardless of whether they may be settled for lesser amounts and remain 
subject to future adjustments based on negotiated settlements with claimants, actions of the RJ Court or other events. 

The RJ Proceedings prompted us to perform a detailed analysis on the completeness and the accuracy of the judicial deposits and 

accounting balances of the other assets of the RJ Debtors. As a result, we identified weaknesses in some of our operational and financial 
reporting controls and procedures. For more information with respect to the identified material weaknesses in Oi’s internal control over 
financial reporting and the steps that Oi has undertaken to remediate these material weaknesses, see “Item 15. Controls and 
Procedures.”. 

Additionally, we determined the need to restate previously issued financial statements and related disclosures to correct errors. 
Accordingly, we are restating our consolidated financial statements for the year ended December 31, 2015. Restatement adjustments 
attributable to fiscal year 2014 and previous fiscal years are reflected as a net adjustment to retained earnings as of January 1, 2015. 

The errors detected and corrected in our financial statements related to our judicial deposits, our provisions for contingencies, 
intragroup balances, tax credits and estimates of revenue from services rendered and not yet billed to customers, as described in “Item 5. 
Operating and Financial Review and Prospects—Financial Presentation and Accounting Policies—Restatement” and note 2 to our 
consolidated financial statements included in this annual report.

Disposition of PT Portugal 

On December 9, 2014, we entered into a share purchase agreement, or the PTP Share Purchase Agreement, with Altice Portugal 

S.A., or Altice Portugal, and Altice S.A. pursuant to which we agreed to sell all of the share capital of PT Portugal to Altice Portugal for 
a purchase price equal to the enterprise value of PT Portugal of €6,900 million, subject to adjustments based on the financial debt, cash 
and working capital of PT Portugal on the closing date, plus an additional earn-out amount of €500 million in the event that the 
consolidated revenues of PT Portugal and its subsidiaries (as of the closing date) for any single year between the year ending 
December 31, 2015 and the year ending December 31, 2019 is equal to or exceeds €2,750 million. We refer to this transaction as the PT 
Portugal Disposition. The PT Portugal Disposition closed on June 2, 2015. 

In connection with the closing of the PT Portugal Disposition, Altice Portugal disbursed €5,789 million, of which €869 million 

was used by PT Portugal to prepay outstanding indebtedness, and €4,920 million was paid to our company in cash. We used a portion 
of the net cash proceeds of the PT Portugal Disposition for the prepayment and repayment at maturity of indebtedness of our company. 

In anticipation of the PT Portugal Disposition, PT Portugal transferred PTIF, its wholly-owned finance subsidiary, to us. As a 
result of this transfer, the indebtedness of PTIF, which had previously been classified as liabilities associated with assets held for sale in 
our consolidated financial statements, was reclassified as indebtedness of our company. In addition, in connection with the PT Portugal 
Disposition, PTIF assumed all obligations under PT Portugal’s outstanding 6.25% Notes due 2016.

In addition, PT Portugal transferred to us all of the outstanding share capital of CVTEL B.V. and Carrigans Finance S.à r.l, as well 

as of PT Participações, SGPS, S.A., or PT Participações, which currently holds: 

•

•

our 86% interest in Africatel Holding B.V., or Africatel, which holds our interests in telecommunications companies in 
Africa, including telecommunications companies in Angola, Cape Verde and São Tomé and Principe; and 

our interests in TPT—Telecomunicações Públicas de Timor, S.A., or TPT, which provides telecommunications, multimedia 
and IT services in Timor Leste in Asia. 

Financial Restructuring 

On March 9, 2016, following the notification of our company on February 25, 2016 that LetterOne Technology (UK) LLP, or 

LetterOne, that it could not proceed with a potential transaction in which LetterOne would make a capital contribution of up to 
US$4.0 billion in our company, contingent on the completion of a potential business combination with TIM Participações S.A., or TIM, 
we retained PJT Partners as our financial advisor to assist us in evaluating financial and strategic alternatives to optimize our liquidity 
and debt profile. 

Although we engaged in negotiations with a the Ad Hoc Group seeking mutual agreement as to the consensual restructuring of the 

indebtedness of our company, after considering the challenges of our economic and financial situation in connection with the maturity 
schedule of our financial debts, the threats to our assets represented by imminent attachments or freezings in judicial lawsuits and the 
urgent need to adopt measures that protect our company, we concluded that filing for judicial reorganization (recuperação judicial) in 
Brazil would be the most appropriate course of action. 

On June 20, 2016, Oi, together with the other RJ Debtors, filed a joint voluntary petition for judicial reorganization pursuant to the 

Brazilian Bankruptcy Law with the RJ Court, pursuant to an urgent measure approved by our board of directors. 

The filing of the petition that commenced the RJ Proceedings was a step towards our financial restructuring. During the RJ 
Proceedings we have, and expect to continue (1) to work to secure new customers while maintaining our service and product sales to all 
market segments, in all of our distribution and customer service channels, (2) to perform installation, maintenance and repair activities 
on a timely basis, (3) to use our workforce as usual, including to perform sales, operating and administrative activities, and (4) to focus 
on our investments in structuring projects aimed at promoting the improvement of service quality and continuing to bring technologic 
advances, high service standards, and innovation to our customers. On June 29, 2016, the RJ Court granted the processing of the RJ 
Proceedings of the RJ Debtors. 

On December 19 and 20, 2017, the GCM was held to consider approval of the most recently filed judicial reorganization plan. The 
GCM concluded on December 20, 2017 following the approval of the RJ Plan reflecting amendments to the judicial reorganization plan 
presented at the GCM as negotiated during the course of the GCM. 

On January 8, 2018, the RJ Court entered the Brazilian Confirmation Order, ratifying and confirming the RJ Plan, according to its 

terms, but modifying certain provisions of the RJ Plan. The Brazilian Confirmation Order was published in the Official Gazette of the 
State of Rio de Janeiro on February 5, 2018, the Brazilian Confirmation Date. 

The Brazilian Confirmation Order, according to its terms, is binding on all parties as long as its effects are not stayed. By 
operation of the RJ Plan and the Brazilian Confirmation Order (provided that no stay or appeal of the Brazilian Confirmation Order 
results in a change of the Brazilian Confirmation Date), the unsecured claims against the RJ Debtors have been novated and discharged 
under Brazilian law and holders of such claims are entitled only to receive the recoveries set forth in the RJ Plan in exchange for their 
claims in accordance with the terms and conditions of the RJ Plan. 

In the context of the RJ Proceedings, certain balances of consolidated assets and liabilities increased as a result of the inclusion of 

the RJ Debtors in RJ Proceedings and the resulting suspension of the payment of certain assumed liabilities. The main balances of 
consolidated assets and liabilities affected were cash, cash equivalents, cash investments, receivables from reciprocal services provided 
to telecom carriers, trade payables, and borrowings and financing. 

We are in the process of implementing the RJ Plan. For more information regarding the RJ Proceedings, see “Item 4. Information 
on the Company—Our Recent History and Development—Our Judicial Reorganization Proceedings.” For more information regarding 
the financial terms of the RJ Plan, see “Item 5. Operating and Financial Review and Prospects—Liability Subject to Compromise.”

On November 18, 2014, Oi’s shareholders acting in an extraordinary general shareholders meeting authorized (1) the reverse split 

of all of Oi’s issued common shares into one common share for each 10 issued common shares, and (2) the reverse split of all of Oi’s 
issued preferred shares into one preferred share for each 10 issued preferred shares. This reverse share split became effective on 
December 22, 2014. There was no change in the ratio of Oi’s Common ADSs or Preferred ADSs in connection with this reverse share 
split; each Common ADS continued to represent one of Oi’s common shares and each Preferred ADS continues to represent one of Oi’s 
preferred shares. All references to numbers of shares of Oi, dividend amounts of Oi and earnings per share of Oi in this annual report 
have been adjusted to give effect to the 10-for-one reverse share split. 

On February 1, 2016, we changed the ratio applicable to Oi’s Common ADSs from one common share per Common ADS to five 
common shares per Common ADS. All references to numbers of Common ADSs in this annual report have been adjusted to give effect 
to this change in ratio. 

Market Share and Other Information 

We make statements in this annual report about our market share and other information relating to the telecommunications 
industry in Brazil. We have made these statements on the basis of information obtained from third-party sources and publicly available 
information that we believe are reliable, such as information and reports from ANATEL, among others. Notwithstanding any 
investigation that we may have conducted with respect to the market share, market size or similar data provided by third parties or 
derived from industry or general publications, we assume no responsibility for the accuracy or completeness of any such information. 

Rounding 

We have made rounding adjustments to reach some of the figures included in this annual report. As a result, numerical figures 

shown as totals in some tables may not be arithmetic aggregations of the figures that precede them.

ITEM 3. KEY INFORMATION 

Selected Financial Information 

The following selected financial data should be read in conjunction with our consolidated financial statements (including the notes 

thereto), “Item 5. Operating and Financial Review and Prospects” and “Presentation of Financial and Other Information.” 

The following selected financial data have been derived from our consolidated financial statements. The selected financial data as 

of December 31, 2017 and 2016 and for the years ended December 31, 2017, 2016 and 2015 have been derived from our audited 
consolidated financial statements included in this annual report. The selected financial data as of December 31, 2015, 2014 and 2013 
and for the years ended December 31, 2014 and 2013 have been derived from our consolidated financial statements that are not 
included in this annual report. 

The RJ Proceedings prompted us to perform a detailed analysis on the completeness and the accuracy of the judicial deposits and 

accounting balances of the other assets of the RJ Debtors. As a result, we identified weaknesses in some of our operational and financial 
reporting controls and procedures. For more information with respect to the identified material weaknesses in Oi’s internal control over 
financial reporting and the steps that Oi has undertaken to remediate these material weaknesses, see “Item 15. Controls and 
Procedures.” 

Additionally, we determined the need to restate previously issued financial statements and related disclosures to correct errors. 
Accordingly, we are restating our consolidated financial statements for the year ended December 31, 2015. Restatement adjustments 
attributable to fiscal year 2014 and previous fiscal years are reflected as a net adjustment to retained earnings as of January 1, 2015. 

The errors detected and corrected in our financial statements related to our judicial deposits, our provisions for contingencies, 
intragroup balances, tax credits and estimates of revenue from services rendered and not yet billed to customers, as described in “Item 5. 
Operating and Financial Review and Prospects—Financial Presentation and Accounting Policies—Restatement” and note 2 to our 
consolidated financial statements included in this annual report. 

In connection with the presentation of financial information as of December 31, 2015, 2014 and 2013 and for the years ended 
December 31, 2014 and 2013, Oi has restated the financial statements related to those dates and periods to correct the errors included in 
these previously issued financial statements. 

We have included information with respect to the dividends and/or interest attributable to shareholders’ equity paid to holders of 

Oi’s common shares and preferred shares since January 1, 2013 in reais and in U.S. dollars translated from reais at the commercial 
market selling rate in effect as of the payment date under the caption “Item 8. Financial Information—Dividends and Dividend 
Policy—Payment of Dividends.”

Exchange Rates 

The Brazilian foreign exchange system allows the purchase and sale of foreign currency and the international transfer of reais by 

any person or legal entity, regardless of the amount, subject to certain regulatory procedures. 

Since 1999, the Brazilian Central Bank has allowed the U.S. dollar-real exchange rate to float freely, and, since then, the U.S. 

dollar-real exchange rate has fluctuated considerably. 

In the past, the Brazilian Central Bank has intervened occasionally to control unstable movements in foreign exchange rates. We 

cannot predict whether the Brazilian Central Bank or the Brazilian government will continue to permit the real to float freely or will 
intervene in the exchange rate market through the return of a currency band system or otherwise. The real may depreciate or appreciate 
against the U.S. dollar and/or the euro substantially. Furthermore, Brazilian law provides that, whenever there is a significant imbalance 
in Brazil’s balance of payments or there are serious reasons to foresee a significant imbalance, temporary restrictions may be imposed 
on remittances of foreign capital abroad. We cannot assure you that such measures will not be taken by the Brazilian government in the 
future. See “—Risk Factors—Risks Relating to Brazil—Restrictions on the movement of capital out of Brazil may impair our ability to 
service certain debt obligations.”

You should consider the following risks as well as the other information set forth in this annual report when evaluating an 
investment in our company. In general, investing in the securities of issuers in emerging market countries, such as Brazil, involves a 
higher degree of risk than investing in the securities of issuers in the United States. Additional risks and uncertainties not currently 
known to us, or those that we currently deem to be immaterial, may also materially and adversely affect our business, results of 
operations, financial condition and prospects. Any of the following risks could materially affect us. In such case, you may lose all or 
part of your original investment. 

Risks Relating to Our Financial Restructuring 

If we fail to comply with certain conditions subsequent set forth in the RJ Plan, the RJ Plan may terminate and we may be declared 
bankrupt under Brazilian law and liquidated. 

On June 20, 2016, Oi, together with the other RJ Debtors, filed a joint voluntary petition for judicial reorganization pursuant to the 

Brazilian Bankruptcy Law with the RJ Court, pursuant to an urgent measure approved by our board of directors. On December 19 and 
20, 2017, the GCM was held to consider approval of the most recently filed judicial reorganization plan. The GCM concluded on 
December 20, 2017 following the approval of the RJ Plan reflecting amendments to the judicial reorganization plan presented at the 
GCM as negotiated during the course of the GCM. On January 8, 2018, the RJ Court entered the Brazilian Confirmation Order, 
ratifying and confirming the RJ Plan, according to its terms, but modifying certain provisions of the RJ Plan. The Brazilian 
Confirmation Order was published in the Official Gazette of the State of Rio de Janeiro on February 5, 2018, the Brazilian 
Confirmation Date. For more information with respect to the RJ Proceedings, see “Item 4. Information on the Company—Our Recent 
History and Development—Our Judicial Reorganization Proceedings.”

The Brazilian Confirmation Order, according to its terms, is binding on all parties as long as its effects are not stayed. By 
operation of the RJ Plan and the Brazilian Confirmation Order (provided that no stay or appeal of the Brazilian Confirmation Order 
results in a change of the Brazilian Confirmation Date), the unsecured claims against the RJ Debtors have been novated and discharged 
under Brazilian law and holders of such claims are entitled only to receive the recoveries set forth in the RJ Plan in exchange for their 
claims in accordance with the terms and conditions of the RJ Plan. As of the date of this annual report, there is no pending stay of the 
Brazilian Confirmation Order, and there are several appeals of the Brazilian Confirmation Order pending (see “Item 4. Information on 
the Company—Our Recent History and Development—Our Judicial Reorganization Proceedings— Confirmation of Judicial 
Reorganization Plan by RJ Court”). We do not believe that the outcome of any of these pending appeals will result in a change of the 
Brazilian Confirmation Date. For more information with respect to the recoveries available with respect to claims against the RJ 
Debtors provided for in the RJ Plan, see “Item 5. Operating and Financial Review and Prospects—Liabilities Subject to Compromise.” 

Under the terms of the RJ Plan, in the event that (1) the Qualified Recovery Settlement Procedure, including the issuance of new 

common shares as part of the recovery of Eligible Bondholders, does not occur on or prior to July 31, 2018, (2) or the Cash Capital 
Increase does not occur on or prior to February 28, 2019, the RJ Plan will automatically terminate and the rights and guarantees of the 
creditors appearing on the Second Creditors List will be restored under the original terms as if the RJ Plan had never been approved, 
unless creditors appearing on the Second Creditors List agree by a simple majority vote of the amount of claims present or represented 
at a meeting of creditors called for that purpose to the total or partial waiver or modification of the conditions described above. If the RJ 
Plan is terminated, creditors appearing on the Second Creditors List will be entitled to (1) approve a modification to the RJ Plan at a 
meeting of creditors complying with the quorum requirements established in the Brazilian Bankruptcy Law, or (2) seek to have the RJ 
Debtors adjudicated as bankrupt by the RJ Court. 

We cannot assure you that the settlement of the Qualified Recovery will occur on or prior to July 31, 2018, that the Cash Capital 

Increase will occur on or prior to February 28, 2019, or that our creditors will agree to a waiver of these conditions in the event that 
these transactions do not occur on a timely basis. As a result, the RJ Plan may automatically terminate. In the event that the RJ Plan 
terminates, we cannot predict (1) whether our creditors will be able to agree on a modification to the RJ Plan that will garner sufficient 
support to be approved by our creditors and confirmed by the RJ Court, (2) what modifications of the RJ Plan could be adopted and the 
impact of these modifications on our company, or (3) whether our creditors would seek to have the RJ Debtors adjudicated as bankrupt 
by the RJ Court, which under Brazilian law is generally followed by a liquidation of the debtors. The termination of the RJ Plan and the 
occurrence of any of these events subsequent to such termination is likely to have a material adverse effect on our business, financial 
condition, results of operations and ability to continue as a going concern.

If the U.S. Bankruptcy Court does not grant an Order giving full force and effect to the RJ Plan and the Brazilian Confirmation Order, 
we may be unable to complete the Qualified Recovery Settlement Procedure and the Non-Qualified Recovery Settlement Procedure, 
which could result in the termination of the RJ Plan. 

Among the claims appearing on the Second Creditors List are claims governed by the laws of New York and other jurisdictions 

within the United States, including obligations under six series of bonds in the aggregate principal amount of R$16,926 million. By 
operation of the RJ Plan and the Brazilian Confirmation Order (provided that no stay or appeal of the Brazilian Confirmation Order 
results in a change of the Brazilian Confirmation Date), the claims with respect to these bonds have been novated and discharged under 
Brazilian law and the holders of these bonds are entitled only to receive the recovery set forth in the RJ Plan in exchange for the claims 
represented by these bonds in accordance with the terms and conditions of the RJ Plan. However, under New York law, the RJ Plan and 
the Brazilian Confirmation Order are ineffective by their terms to novate these bonds and extinguish the obligations represented by 
these bonds. 

In connection with the commencement of the RJ Proceedings, on June 21, 2016, the Chapter 15 Debtors, including the issuers and 
guarantors of our bonds that are governed under New York law, sought relief under Chapter 15 of the United States Bankruptcy Code. 
On July 22, 2016, the U.S. Bankruptcy Court granted the U.S. Recognition Order, as a result of which a stay was automatically applied, 
preventing (1) the filing, in the United States, of any actions against the Chapter 15 Debtors or their properties located within the 
territorial jurisdiction of the United States, and (2) parties from terminating their existing U.S. contracts with the Chapter 15 Debtors. 
For more information with respect to the Chapter 15 Proceedings, see “Item 4. Information on the Company—Our Recent History and 
Development—Recognition Proceedings in the United States.” 

On April 17, 2018, the foreign representative for the Chapter 15 Debtors filed a motion with the U.S. Bankruptcy Court seeking an 
order of that court granting, among other things, full force and effect to the RJ Plan and the Brazilian Confirmation Order in the United 
States. The deadline for objections to the proposed order set by the U.S. Bankruptcy Court was May 11, 2018. As of that date, Pharol, 
Bratel B.V. and Bratel S.à r.l. filed an objection to that motion in which they argued that the motion should be denied without prejudice 
or deferred consideration until after certain appellate proceedings, arbitration and mediation have been concluded in Brazil. 
Additionally, The Bank of New York Mellon filed a limited objection requesting to revise certain portions of the proposed order, but 
did not object to the motion itself. The U.S. Bankruptcy Court has scheduled a hearing on the objections to the proposed order on May 
29, 2018. If the U.S. Bankruptcy Court grants the requested order, the claims with respect to our bonds issued under indentures 
governed by New York law will be novated and discharged under New York law and the holders of these bonds will be entitled only to 
receive the recovery set forth in the RJ Plan in exchange for the claims represented by these bonds. 

We are constrained from implementing the Qualified Recovery Settlement Procedure and the Non-Qualified Recovery Settlement 

Procedure prior to the date on which the U.S. Bankruptcy Court grants the requested order because, although we would be able to 
cancel the bonds surrendered by holders that had made valid recovery elections and are entitled to receive the Qualified Recovery and 
the Non-Qualified Recovery, we would be unable to cancel the remaining bonds issued under our indentures governed by New York 
law and holders of these bonds could take action in the United States to recover the full principal amount of these bonds. Should holders 
take such actions successfully, we are unlikely to be able to fund the payment of such judgments, which would have a material adverse 
effect on our business, financial condition, results of operations and ability to continue as a going concern. 

If the U.S. Bankruptcy Court does not grant the requested order or if the order is granted, but there is not sufficient time for us to 

complete the Qualified Recovery Settlement Procedure prior to July 31, 2018, the RJ Plan may terminate. The termination of the RJ 
Plan and the occurrence of events subsequent to such termination is likely to have a material adverse effect on our business, financial 
condition, results of operations and ability to continue as a going concern. 

If we fail to meet the conditions set forth in the RJ Plan for the issuance of new common shares as part of the Qualified Recovery, and 
these conditions are not waived, we may be unable to complete the Qualified Recovery Settlement Procedure, which could result in the 
termination of the RJ Plan. 

The terms of the RJ Plan require that we satisfy certain conditions precedent prior to issuing new common shares as part of the 

Qualified Recovery Settlement Procedure, including the requirements that (1) the claims of ANATEL are novated and restructured 
under the RJ Plan, (2) ANATEL has not submitted new answers or appeals in court nor insisted on answers or appeals in court existing 
on the date of the approval of the RJ Plan in relation to the RJ Plan, including the novation and/or restructuring of its claims, and 
(3) ANATEL has granted all regulatory necessary authorizations for the implementation of the issuance of new common shares as part 
of the Qualified Recovery Settlement Procedure. The RJ Plan provides that if these conditions are not satisfied, they may be waived by 
a majority of the claims of Qualified Bondholders present at a meeting called for that purpose.

We cannot assure you that each of the conditions to the issuance of new common shares as part of the Qualified Recovery 
Settlement Procedure will be satisfied or waived with sufficient time for us to complete the Qualified Recovery Settlement Procedure 
prior to July 31, 2018, or at all. In the event that these conditions are not satisfied or waived in a timely manner and we are unable to 
complete the Qualified Recovery Settlement Procedure prior to July 31, 2018, the RJ Plan may terminate. The termination of the RJ 
Plan and the occurrence of events subsequent to such termination is likely to have a material adverse effect on our business, financial 
condition, results of operations and ability to continue as a going concern. 

If the creditors of PTIF do not vote to approve the PTIF Composition Plan, we expect that PTIF will be liquidated, which could have a 
material adverse effect on our financial condition and liquidity. 

Although the RJ Proceedings have been recognized in the United States, England and Wales and Portugal, the laws of The 
Netherlands do not provide for the recognition of the RJ Proceedings. PTIF is organized under the laws of The Netherlands. On 
April 19, 2017, a pending suspension of payments proceeding in respect of PTIF was converted into a Dutch bankruptcy proceeding. 
For more information with respect to PTIF’s Dutch bankruptcy proceeding, see “Item 4. Information on the Company—Our Recent 
History and Development—Our Judicial Reorganization Proceedings—Restructuring of Dutch Finance Subsidiaries.” 

On April 10, 2018, PTIF deposited a draft of the PTIF Composition Plan with the Dutch Court. The PTIF Composition Plan 

provides for the restructuring of the claims against PTIF on substantially the same terms and conditions as the RJ Plan. On April 10, 
2018, Oi launched an English law consent solicitation to the holders of the seven series of bonds issued by PTIF seeking their votes to 
approve extraordinary resolutions: (a) releasing of Oi’s guarantee of the relevant series of bonds, (b) authorizing and instructing the 
trustee of the PTIF bonds to submit a claim on behalf of all the outstanding PTIF bonds and vote in favor of the PTIF Composition Plan 
on behalf of the PTIF bondholders and (c) authorizing the trustee of the PTIF bonds to request the PTIF Bankruptcy Trustee vote in 
favor of the Oi Coop Composition Plan in respect of its vote in respect of the PTIF intercompany claim owed by Oi Coop to PTIF. 

Under the documents governing the bonds issued by PTIF, these actions may be taken at a meeting of holders of each series of 
bonds at which at least two-thirds of the principal amount of the applicable bonds are represented in person or by proxy. In the event 
that quorum is not obtained at any such initial meeting, these actions may be taken at an adjourned meeting of holders of the applicable 
series of bonds at which at least one-third of the principal amount of the applicable bonds are represented in person or by proxy. In 
either case, the proposed extraordinary resolutions may be passed by the vote of not less than 75% of the principal amount of the 
applicable bonds represented in the meeting. 

The voting deadline in relation to this consent solicitation was April 27, 2018 for one of these series of bonds and April 30, 2018 

for the other six series of bonds. Bondholder meetings of each of these series of bonds were held on May 2, 2018, however, quorum 
was not achieved for any of these series of bonds. As a result, on May 3, 2018, Oi published notices to convene adjourned meetings of 
each of these series of bonds on May 17, 2018 and establishing a new voting deadline of May 14, 2018. Based on the votes received as 
of the second voting deadline, we believe that each of the extraordinary resolutions will be passed and that each of these series of bands 
will vote to approve the PTIF Composition Plan. 

A meeting of the creditors of PTIF has been scheduled for June 1, 2018 in the Netherlands in respect of the PTIF Composition 

Plan at which the creditors of PTIF will consider the PTIF Composition Plan and vote whether to approve it. If the extraordinary 
resolutions have been passed by each series of the bonds, the trustee of the bonds will vote on behalf of the PTIF bonds at the creditors 
meeting. The PTIF Composition Plan will be approved if a majority in number and value of its creditors vote in its favor. We expect 
that the creditors of PTIF will approve the PTIF Composition Plan, however we cannot assure you that procedural matters will not be 
raised at this meeting of creditors that will result in the failure of the creditors to approve the PTIF Composition Plan. 

If the PTIF Composition Plan is approved at the meeting of the creditors of PTIF, the Dutch Court will schedule a hearing on or 

prior to June 15, 2018 to rule on the homologation of the PTIF Composition Plan. Although we expect that the Dutch Court will 
homologate the PTIF Composition Plan at that hearing, we cannot assure you that procedural matters will not be raised at this hearing 
that will result in the failure of the Dutch Court to homologate the PTIF Composition Plan. If the PTIF Composition Plan is 
homologated, the PTIF Composition Plan will be given full force and effect and recognized in the European Union under the European 
Insolvency Regulation 2015/848, including in England and Wales. 

In the event that the PTIF Composition Plan is not approved at the meeting of the creditors of PTIF or the Dutch Court fails to 

homologate the PTIF Composition Plan, we expect that the Dutch Court will order the liquidation of PTIF. In the event of the 
liquidation of PTIF, we expect that the PTIF Bankruptcy Trustee will seek to collect on PTIF’s assets, a substantial portion of which 
consists of intercompany loans made to Oi Coop that have been discharged under the RJ Plan, and distribute the proceeds to the 
creditors of PTIF.

In the event that the extraordinary resolutions are not passed by each series of PTIF bonds, the guarantee granted by Oi in respect 

of the PTIF bonds will remain in place. If the indebtedness of PTIF is not discharged under the PTIF Composition Plan, holders of 
bonds issued by PTIF that are eligible to participate in the Qualified Recovery Settlement Procedure and the Non-Qualified Recovery 
Settlement Procedure may not surrender these bonds and such holders, together with other holders of these bonds that are not eligible to 
participate in the Qualified Recovery Settlement Procedure or the Non-Qualified Recovery Settlement Procedure, may seek to enforce 
Oi’s guarantee, which would have a material adverse effect on our financial condition, results of operations and ability to continue as a 
going concern. 

If the creditors of Oi Coop do not vote to approve the Oi Coop Composition Plan, we expect that Oi Coop will be liquidated, which 
could have a material adverse effect on our financial condition and liquidity. 

Although the RJ Proceedings have been recognized in the United States, England and Wales and Portugal, the laws of The 
Netherlands do not provide for the recognition of the RJ Proceedings. Oi Coop is organized under the laws of The Netherlands. On 
April 19, 2017, a pending suspension of payments proceeding in respect of Oi Coop was converted into a Dutch bankruptcy proceeding. 
For more information with respect to Oi Coop’s Dutch bankruptcy proceeding, see “Item 4. Information on the Company—Our Recent 
History and Development—Our Judicial Reorganization Proceedings—Restructuring of Dutch Finance Subsidiaries.” 

On April 10, 2018, Oi Coop deposited a draft of the Oi Coop Composition Plan with the Dutch Court. The Oi Coop Composition 

Plan provides for the restructuring of the claims against Oi Coop on substantially the same terms and conditions as the RJ Plan. On 
April 10, 2018, Oi Coop issued an information memorandum to the holders of the two series of bonds issued by Oi Coop in relation to 
the Oi Coop Composition Plan. The voting deadline in relation to the information memorandum was May 15, 2018. As of the voting 
deadline, the tabulation is in the process of being finalized. 

A meeting of the creditors of Oi Coop has been scheduled for June 1, 2018 in the Netherlands at which the creditors of Oi Coop 

will consider the Oi Coop Composition Plan and vote whether to approve it. The votes submitted by holders of the Oi Coop bonds 
pursuant to the information memorandum shall be applied in this vote and it is expected the PTIF Bankruptcy Trustee will also vote in 
favor of the Oi Coop Composition Plan in relation to an intercompany loan made by PTIF to Oi Coop. The Oi Coop Composition Plan 
will be approved if a majority in number and value of its creditors vote in its favor. Based on the preliminary results of the voting 
solicitation and if the PTIF Bankruptcy Trustee votes in favor of the Oi Coop composition, we expect Oi Coop Composition Plan will 
be approved, however we cannot assure you that procedural matters will not be raised at this meeting of creditors that will result in the 
failure of the creditors to approve the Oi Coop Composition Plan. If the extraordinary resolutions of the PTIF bonds are not passed by 
all series of PTIF bonds, we cannot assure you as to how the PTIF Bankruptcy Trustee will vote the claim represented by an 
intercompany loan made by PTIF to Oi Coop, and if the PTIF Bankruptcy Trustee vote this claim against approval of the Oi Coop 
Composition Plan, we expect the Oi Coop Composition Plan will not be approved. 

If the Oi Coop Composition Plan is approved at the meeting of the creditors of Oi Coop, the Dutch Court will schedule a hearing 

on or prior to June 15, 2018 to rule on the homologation of the Oi Coop Composition Plan. Although we expect that the Dutch Court 
will homologate the Oi Coop Composition Plan at that hearing, we cannot assure you that procedural matters will not be raised at this 
hearing that will result in the failure of the Dutch Court to homologate the Oi Coop Composition Plan. 

In the event that the Oi Coop Composition Plan is not approved at the meeting of the creditors of Oi Coop or the Dutch Court fails 
to homologate the Oi Coop Composition Plan, we expect that the Dutch Court will order the liquidation of Oi Coop. In the event of the 
liquidation of Oi Coop, we expect that the Oi Coop Bankruptcy Trustee will seek to collect on Oi Coop’s assets, a substantial portion of 
which consists of intercompany loans made to Oi Mobile that have been discharged under the RJ Plan, and distribute the proceeds to the 
creditors of Oi Coop. 

The bonds issued by Oi Coop are guaranteed by Oi. If the indebtedness of Oi Coop is not discharged under the Oi Coop 

Composition Plan and the U.S. Bankruptcy Court does not grant the order requesting that full force and effect be given to the RJ Plan 
and the Brazilian Confirmation Order in the United States, holders of bonds issued by Oi Coop that are eligible to participate in the 
Qualified Recovery Settlement Procedure and the Non-Qualified Recovery Settlement Procedure may not surrender these bonds and 
such holders, together with other holders of these bonds that are not eligible to participate in the Qualified Recovery Settlement 
Procedure or the Non-Qualified Recovery Settlement Procedure, may seek to enforce Oi’s guarantee, which would have a material 
adverse effect on our financial condition, results of operations and ability to continue as a going concern.

If the indebtedness of Oi Coop is not discharged under the Oi Coop Composition Plan and the U.S. Bankruptcy Court grants the 
order requesting that full force and effect be given to the RJ Plan and the Brazilian Confirmation Order in the United States, holders of 
bonds issued by Oi Coop that are eligible to participate in the Qualified Recovery Settlement Procedure and the Non-Qualified 
Recovery Settlement Procedure may not surrender these bonds and such holders, together with other holders of these bonds that are not 
eligible to participate in the Qualified Recovery Settlement Procedure or the Non-Qualified Recovery Settlement Procedure, may seek 
to enforce Oi’s guarantee in The Netherlands, notwithstanding any discharge of this guarantee under New York law as a result of an 
order of the U.S. Bankruptcy Court. We cannot assure you regarding the results of any such action, or the effect of demands on our 
management’s time in defending any such action on management’s ability to devote its attention to our business, either of which could 
result in a material adverse effect on our business and results of operations. 

Following the implementation of the RJ Plan, our debt instruments will contain covenants that could restrict our financing and 
operating flexibility and have other adverse consequences. 

As of December 31, 2017, we had loans and financings of R$49,130 million classified as liabilities subject to compromise. 
Following the implementation of the RJ Plan, the outstanding amount of our loans and financings will be substantially reduced, 
however we will be subject to certain financial covenants under the instruments that govern our indebtedness that limit our ability to 
incur additional debt. The level of our consolidated indebtedness and the requirements and limitations imposed by these debt 
instruments could adversely affect our financial condition or results of operations. In particular, the terms of some of these debt 
instruments restrict our ability, and the ability of our subsidiaries, to: 

•

•

•

•

•

incur additional debt; 

grant liens; 

pledge assets; 

sell or dispose of assets; and 

make certain acquisitions, mergers and consolidations. 

If we are unable to incur additional debt, we may be unable to invest in our business and make necessary or advisable capital 

expenditures, which could reduce future net operating revenue and adversely affect our profitability. In addition, the cash required to 
service our indebtedness reduces the amount available to us to make capital expenditures. If we are unable to generate operating cash 
flows, we may not be able to continue servicing our debt. 

Under the RJ Plan, until the fifth anniversary of the Brazilian Confirmation Date, we are required to apply an amount equivalent to 

100% of the net revenue from our sale of assets in excess of US$200 million to investments in our activities. Beginning on the sixth 
anniversary of the Brazilian Confirmation Date, we are required to allocate to the repayment of debt instruments representing recoveries 
under the RJ Plan on an annual basis an amount equivalent to 70% of the amount by which (1) our cash and cash equivalents and 
financial investments at the end of each fiscal year exceeds (2) the greater of (a) 25% of our operating expenses and capital expenses for 
that fiscal year, and (b) R$5,000 million, subject to adjustment in the event that we conclude any capital increases. The cash required to 
make these repayments will reduce the amount available to us to make capital expenditures. 

If we are unable to meet our debt service obligations or comply with our debt covenants, we could be forced to renegotiate or 
refinance our indebtedness or seek additional equity capital. In this circumstance, we may be unable to obtain financing on satisfactory 
terms, or at all. 

For more information regarding the debt instruments that we expect will obligate our company following the implementation of 

the RJ Pan, see “Item 5. Operating and Financial Review and Prospects—Liabilities Subject to Compromise.” 

We may not be able to successfully implement the Cash Capital Increase, which could impair our ability to implement the capital 
expenditures contemplated by our business plan and could result in the termination of the RJ Plan. 

Under the terms of the RJ Plan, we are required to implement the Cash Capital Increase on or prior to February 28, 2019. In the 
event that the Cash Capital Increase does not occur on or prior to February 28, 2019, the RJ Plan will automatically terminate and the 
rights and guarantees of the creditors appearing on the Second Creditors List will be restored under the original terms as if the RJ Plan 
had never been approved, unless creditors appearing on the Second Creditors List agree by a simple majority vote of the amount of 
claims present or represented at a meeting of creditors called for that purpose to the total or partial waiver or modification of the 
conditions described above.

As part of the RJ Plan, we negotiated the terms of the Commitment Agreement with members of the Ad Hoc Group, the IBC and 

certain other unaffiliated bondholders under which such bondholders agreed to backstop the Cash Capital Increase. The commitments of 
these parties are subject to our satisfaction of certain conditions, including, among others, our compliance with the terms of the RJ Plan, 
the distribution of our shares currently held by PTIF, the completion of the Qualified Recovery Settlement Procedures, the 
homologation of the Oi Coop Composition Plan and the PTIF Composition Plan, the issuance of the requested order by the U.S. 
Bankruptcy Court, and the adoption by ANATEL of a new General Plan of Universal Access Targets reducing the universal access 
targets applicable to our company. We cannot assure you that each of these conditions will be met or waived by the parties to the 
Commitment Agreement in a timely fashion so as to permit the conclusion of the Cash Capital Increase on or prior to 
February 28, 2019. 

In the event that we are unable to implement the Cash Capital Increase, either directly or through the exercise of our rights under 
the Commitment Agreement, we may be unable to fund the capital expenditures included in our business plan, which are necessary for 
us to modernize our infrastructure in order to successfully compete in the Brazilian telecommunications sectors. Our failure to do so is 
likely to have a material adverse effect on our business, financial condition, results of operations and ability to continue as a going 
concern. 

In addition, our failure to implement the Cash Capital Increase on or prior to February 28, 2019 could result in the termination of 

the RJ Plan, and the occurrence of events subsequent to such termination is likely to have a material adverse effect on our business, 
financial condition, results of operations and ability to continue as a going concern. 

General Risks Relating to the Telecommunications Industry 

The telecommunications industry is subject to frequent changes in technology. Our ability to remain competitive depends on our ability 
to implement new technology, and it is difficult to predict how new technology will affect our business. 

Companies in the telecommunications industry must adapt to rapid and significant technological changes that are usually difficult 

to anticipate. The mobile telecommunications industry in particular has experienced rapid and significant technological development 
and frequent improvements in capacity, quality and data-transmission speed. Technological changes may render our equipment, 
services and technology obsolete or inefficient, which may adversely affect our competitiveness or require us to increase our capital 
expenditures in order to maintain our competitive position. In addition, personal mobility service providers in Brazil are experiencing 
increasing competition from over-the-top, or OTT, providers, which provide content (such as WhatsApp, Skype and YouTube) over an 
internet connection rather than through a service provider’s network. OTT providers are becoming increasingly competitive as 
customers shift from mobile voice and SMS communications to internet-based voice and data communications through computers and 
smartphone or tablet applications. It is possible that alternative technologies may be developed that are more advanced than those we 
currently provide. We may not obtain the expected benefits of our investments if more advanced technologies are adopted by the 
market. Even if we adopt new technologies in a timely manner as they are developed, the cost of such technology may exceed the 
benefit to us, and we cannot assure you that we will be able to maintain our level of competitiveness. 

Our operations depend on our ability to maintain, upgrade and operate efficiently our accounting, billing, customer service, 
information technology and management information systems and to rely on the systems of other carriers under co-billing agreements. 

Sophisticated information and processing systems are vital to our growth and our ability to monitor costs, render monthly invoices 

for services, process customer orders, provide customer service and achieve operating efficiencies. We cannot assure you that we will 
be able to operate successfully and upgrade our accounting, information and processing systems or that these systems will continue to 
perform as expected. We have entered into co-billing agreements with each long-distance telecommunications service provider that is 
interconnected to our networks in Brazil to include in our invoices the long-distance services rendered by these providers, and these 
providers have agreed to include charges owed to us in their invoices. Any failure in our accounting, information and processing 
systems, or any problems with the execution of invoicing and collection services by other carriers with whom we have co-billing 
agreements, could impair our ability to collect payments from customers and respond satisfactorily to customer needs, which could 
adversely affect our business, financial condition and results of operations. 

Improper use of our networks could adversely affect our costs and results of operations. 

We may incur costs associated with the unauthorized and fraudulent use of our networks, including administrative and capital 
costs associated with detecting, monitoring and reducing the incidence of fraud. Fraud also affects interconnection costs and payments 
to other carriers for non-billable fraudulent roaming. Improper use of our network could also increase our selling expenses if we need to 
increase our provision for doubtful accounts to reflect amounts we do not believe we can collect for improperly made calls. Any 
increase in the improper use of our network in the future could materially adversely affect our costs and results of operations.

Our business is dependent on our ability to expand our services and to maintain the quality of the services provided. 

Our business as a telecommunications services provider depends on our ability to maintain and expand our telecommunications 

services network. We believe that our expected growth will require, among other things: 

•

•

•

•

•

continuous development of our operational and administrative systems; 

increasing marketing activities; 

improving our understanding of customer wants and needs; 

continuous attention to service quality; and 

attracting, training and retaining qualified management, technical, customer relations, and sales personnel.

We believe that these requirements will place significant demand on our managerial, operational and financial resources. Failure 

to manage successfully our expected growth could reduce the quality of our services, with adverse effects on our business, financial 
condition and results of operations. 

Our operations are also dependent upon our ability to maintain and protect our network. Failure in our networks, or their backup 

mechanisms, may result in service delays or interruptions and limit our ability to provide customers with reliable service over our 
networks. Some of the risks to our networks and infrastructure include (1) physical damage to access lines and long-distance optical 
cables; (2) power surges or outages; (3) software defects; (4) disruptions beyond our control; (5) breaches of security; and (6) natural 
disasters. The occurrence of any such event could cause interruptions in service or reduce capacity for customers, either of which could 
reduce our net operating revenue or cause us to incur additional expenses. In addition, the occurrence of any such event may subject us 
to penalties and other sanctions imposed by ANATEL, and may adversely affect our business and results of operations. 

We face various cyber-security risks that, if not adequately addressed, could have an adverse effect on our business. 

We face various cyber-security risks that could result in business losses, including but not limited to contamination (whether 
intentional or accidental) of our networks and systems by third parties with whom we exchange data, equipment failures, unauthorized 
access to and loss of confidential customer, employee and/or proprietary data by persons inside or outside of our organization, cyber 
attacks causing systems degradation or service unavailability, the penetration of our information technology systems and platforms by 
ill-intentioned third parties, and infiltration of malware (such as computer viruses) into our systems. Cyber attacks against companies 
have increased in frequency, scope and potential harm in recent years. Further, the perpetrators of cyber attacks are not restricted to 
particular groups or persons. These attacks may be committed by company employees or third parties operating in any region, including 
jurisdictions where law enforcement measures to address such attacks are unavailable or ineffective We may not be able to successfully 
protect our operational and information technology systems and platforms against such threats. Further, as cyber attacks continue to 
evolve, we may incur significant costs in the attempt to modify or enhance our protective measures or investigate or remediate any 
vulnerability. The inability to operate our networks and systems as a result of cyber attacks, even for a limited period of time, may result 
in significant expenses to us and/or a loss of market share to other communications providers. The costs associated with a major cyber 
attack could include expensive incentives offered to existing customers and business partners to retain their business, increased 
expenditures on cyber-security measures and the use of alternate resources, lost revenues from business interruption and litigation. If we 
are unable to adequately address these cyber-security risks, or operating network and information systems could be compromised, 
which would have an adverse effect on our business, financial condition and results of operations. 

The mobile telecommunications industry and participants in this industry, including us, may be required to adopt an extensive program 
of field measurements of radio frequency emissions and be subject to further regulation and/or claims based on concerns regarding 
potential health problems and interfere with medical devices. 

Media and other entities have suggested that the electromagnetic emissions from mobile handsets and base stations may cause 
health problems. If consumers harbor health-related concerns, they may be discouraged from using mobile handsets. These concerns 
could have an adverse effect on the mobile telecommunications industry and, possibly, expose mobile services providers to litigation. 
We cannot assure you that further medical research and studies will refute a link between the electromagnetic emissions of mobile 
handsets and base stations, including on frequency ranges we use to provide mobile services, and these health concerns. Government 
authorities could increase regulation on electromagnetic emissions of mobile handsets and base stations, which could have an adverse 
effect on our business, financial condition and results of operations. The expansion of our network may be affected by these perceived 
risks if we experience problems in finding new sites, which in turn may delay the expansion and may affect the quality of our services.

In July 2002, ANATEL enacted regulations that limit emission and exposure for fields with frequencies between 9 kHz and 300 
GHz. In May 2009, Law No. 11,934 was enacted, which established the need for field measurements by telecommunications service 
providers of all radio-communication transmitting stations every five years with respect to emission and exposure to these fields. In 
October 2017, ANATEL published new regulations which provide for the reevaluation of regulations regarding human exposure to 
radiofrequency electromagnetic fields and the form of the field measurements mandated by Law No. 11,934. ANATEL is in the process 
of creating a working group, without the participation of the telecommunications service providers, to analyze the impact of these new 
regulations. We expect that this working group will be created in the first half of 2018. We cannot predict the scope of the technical and 
financial impact of these new regulations on our company.

Risks Relating to Our Company 

We have identified various material weaknesses in our internal control over financial reporting which have materially adversely 
affected our ability to timely and accurately report our results of operations and financial condition. These material weaknesses may 
not have been fully remediated as of the filing date of this annual report and we cannot assure you that other material weaknesses will 
not be identified in the future. 

Under the supervision and with the participation of our chief executive officer and our chief financial officer, our management 

conducted an assessment of the effectiveness of our internal control over financial reporting as of December 31, 2017 based on the 
criteria established in “Internal Control—Integrated Framework (2013)” issued by the Committee of Sponsoring Organizations of the 
Treadway Commission. Based on this assessment, our management concluded that as of December 31, 2017, our internal control over 
financial reporting was not effective because material weaknesses existed. A material weakness is a control deficiency, or combination 
of control deficiencies, in internal control over financial reporting such that there is a reasonable possibility that a material misstatement 
of the annual consolidated financial statements will not be prevented or detected on a timely basis. These deficiencies resulted in 
material misstatements to the Company’s financial statements for 2015 and previous years, which were corrected through restatement of 
those periods, and to the preliminary 2016 and 2017 financial statements, which were corrected prior to issuance. For more information 
about these material weaknesses, see “Item 15. Controls and Procedures.” 

Although we have implemented and continue to implement measures designed to remediate these material weaknesses and, in the 

short term, to mitigate the potential adverse effects of these material weaknesses, our assessment of the impact of these measures has 
not been completed as of the filing date of this annual report and we cannot assure you that these measures are adequate. Moreover, we 
cannot assure you that additional material weaknesses in our internal control over financial reporting will not arise or be identified in 
the future. 

As a result, we must continue our remediation activities and must also continue to improve our operational, information 

technology, and financial systems, infrastructure, procedures, and controls, as well as continue to expand, train, retain, and manage our 
employee base. Any failure to do so, or any difficulties we encounter during implementation, could result in additional material 
weaknesses or in material misstatements in our financial statements. These misstatements could result in a future restatement of our 
financial statements, could cause us to fail to meet our reporting obligations, or could cause investors to lose confidence in our reported 
financial information, which could materially adversely affect our business, financial condition and results of operations and may 
generate negative market reactions, potentially leading to a decline in the price of Oi’s common shares, preferred shares or ADSs. 

We rely on strategic suppliers of equipment, materials and certain services necessary for our operations and expansion. If these 
suppliers fail to provide equipment, materials or services to us on a timely basis, we could experience disruptions, which could have an 
adverse effect on our revenues and results of operations. 

We rely on a few strategic suppliers of equipment and materials, including Huawei do Brasil Telecomunicações Ltda. and 
Ericsson Telecomunicações S.A., to provide us with equipment and materials that we need in order to expand and to operate our 
business in Brazil. In addition, we rely on a third-party provider of network maintenance services in certain regions were we operate. 
There are a limited number of suppliers with the capability of providing the mobile network equipment and fixed-line network 
platforms that our operations and expansion plans require or the services that we require to maintain our networks. In addition, because 
the supply of mobile network equipment and fixed-line network platforms requires detailed supply planning and this equipment is 
technologically complex, it would be difficult for our company to replace the suppliers of this equipment. Suppliers of cables that we 
need to extend and maintain our networks may suffer capacity constraints or difficulties in obtaining the raw materials required to 
manufacture these cables. As a result, we are exposed to risks associated with these suppliers, including restrictions of production 
capacity for equipment and materials, availability of equipment and materials, delays in delivery of equipment, materials or services, 
and price increases. If these suppliers or vendors fail to provide equipment, materials or services to us on a timely basis or otherwise in 
compliance with the terms of our contracts with these suppliers, we could experience disruptions or declines in the quality of our 
services, which could have an adverse effect on our revenues and results of operations, and we might be unable to satisfy the 
requirements contained in our concession and authorization agreements.

We are subject to numerous legal and administrative proceedings, which could adversely affect our business, results of operations and 
financial condition. 

We are subject to numerous legal and administrative proceedings. It is difficult to quantify the potential impact of these legal and 

administrative proceedings. We classify our risk of loss from legal and administrative proceedings as “probable,” “possible” or 
“remote.” We make provisions for probable losses but do not make provisions for possible and remote losses. 

As a result of the RJ Proceedings, we have applied ASC 852 in preparing our consolidated financial statements. ASC 852 requires 
that financial statements separately disclose and distinguish transactions and events that are directly associated with our reorganization 
from the transactions and events that are associated with the ongoing operations of our business. Accordingly, our prepetition 
obligations, including certain of our legal contingencies, that may be impacted by the RJ Proceedings based on our assessment of these 
obligations following the guidance of ASC 852 have been classified on our balance sheet as “Liabilities subject to compromise.” 
Prepetition liabilities subject to compromise are required to be reported at the amount allowed as a claim by the RJ Court, regardless of 
whether they may be settled for lesser amounts and remain subject to future adjustments based on negotiated settlements with claimants, 
actions of the RJ Court or other events. As of December 31, 2017 and 2016, the aggregate amount of legal contingencies recognized by 
the RJ Court was R$13,162 million and R$11,614 million, respectively. For more information about the impact of the RJ Proceedings 
on our legal proceedings, see “Item 5. Operating and Financial Review and Prospects—Liabilities Subject to Compromise—Labor 
Contingencies,” “—Civil Contingencies – ANATEL,” and “—Civil Contingencies – Other Claims” and note 28 to our consolidated 
financial statements included in this annual report. 

In addition, as of December 31, 2017 and 2016, the total estimated amount in controversy for those proceedings not subject to the 

RJ Plan in respect of which the risk of loss was deemed probable or possible totaled approximately R$27,789 million and 
R$27,299 million, respectively, and we had established provisions of $1,368 million and R$1,129 million, respectively, relating to these 
proceedings. Our provisions for legal contingencies are subject to monthly monetary adjustments. For a detailed description of our 
provisions for contingencies, see note 18 to our consolidated financial statements included in this annual report. 

We are not required to disclose or record provisions for proceedings in which our management judges the risk of loss to be remote. 

However, the amounts involved in certain of the proceedings in which we believe our risk of loss is remote could be substantial. 
Consequently, our losses could be significantly higher than the amounts for which we have recorded provisions. 

If we are subject to unfavorable decisions in any legal or administrative proceedings and the losses in those proceedings 
significantly exceed the amount for which we have provisioned or involve proceedings for which we have made no provision, our 
results of operations and financial condition may be materially adversely affected. Even for the amounts recorded as provisions for 
probable losses, a judgment against us would have an effect on our cash flow if we are required to pay those amounts. Unfavorable 
decisions in these legal proceedings may, therefore, reduce our liquidity and adversely affect our business, financial condition and 
results of operations. For a more detailed description of these proceedings, see “Item 8. Financial Information—Legal Proceedings.” 

We have indemnification obligations with respect to the PT Exchange and the PT Portugal Disposition that could materially adversely 
affect our financial position. 

In the exchange agreement, or the PT Exchange Agreement, that we entered into with Pharol under which we transferred defaulted 

commercial paper of Rio Forte Investments S.A., or Rio Forte, to Pharol in exchange for the delivery to our company of Oi’s common 
shares and preferred shares as described under “Item 7. Major Shareholders and Related Party Transactions—Major Shareholders—PT 
Option Agreement,” we agreed to indemnify Pharol against any loss arising from (1) Pharol’s contingent or absolute tax or anti-trust 
obligations in relation to the assets contributed to our company in the Oi capital increase in connection with which we acquired PT 
Portugal from Pharol in May 2014 and (2) Pharol’s management activities, with reference to acts or triggering events occurring on or 
prior to May 5, 2014, excluding any losses incurred by Pharol as a result of the financial investments in the Rio Forte commercial paper 
and the acquisition of the Rio Forte commercial paper from Oi under the PT Exchange Agreement. 

In the PTP Share Purchase Agreement under which we sold PT Portugal in the PT Portugal Disposition, we agreed to indemnify 

Altice Portugal for breaches of our representations and warranties under the PTP Share Purchase Agreement, subject to certain 
customary procedural and financial limitations. There can be no assurance that we will not be subject to significant claims under these 
indemnification provisions and if we are subject to such claims under these indemnification provisions, we could be required to pay 
significant amounts, which would have an adverse effect on our financial condition.

We are subject to potential liabilities relating to our third-party service providers, which could have a material adverse effect on our 
business, financial condition and results of operations. 

We are subject to potential liabilities relating to our third-party service providers in Brazil. Such potential liabilities may involve 
claims by employees of third-party service providers in Brazil directly against us as if we were the direct employer of such employees, 
as well as claims against us for secondary liability for, among other things, occupational hazards, wage parity or overtime pay, in the 
event that such third-party service providers fail to meet their obligations to their employees. We have not recorded any provisions for 
such claims, and significant judgments against us could have a material adverse effect on our business, financial condition and results of 
operations. 

We are subject to delinquencies of our accounts receivables. If we are unable to limit payment delinquencies by our customers, or if 
delinquent payments by our customers increase, our financial condition and results of operations could be adversely affected. 

Our business significantly depends on our customers’ ability to pay their bills and comply with their obligations to us. During 

2017, we recorded provisions for doubtful accounts in the amount of R$692 million, or 2.9% of our net operating revenue, primarily 
due to subscribers’ delinquencies. During 2016, we recorded provisions for doubtful accounts in the amount of R$643 million, or 2.5% 
of our net operating revenue, primarily due to subscribers’ delinquencies. As of December 31, 2017 and 2016, our provision for 
doubtful accounts was R$1,085 million and R$1,342 million, respectively. 

ANATEL regulations prevent us from implementing certain policies that could have the effect of reducing delinquency of our 
customers in Brazil, such as service restrictions or limitations on the types of services provided based on a subscriber’s credit record. If 
we are unable to successfully implement policies to limit delinquencies of our Brazilian subscribers or otherwise select our customers 
based on their credit records, persistent subscriber delinquencies and bad debt will continue to adversely affect our operating and 
financial results. 

In addition, if the Brazilian economy declines due to, among other factors, a reduction in the level of economic activity, an 
increase in inflation or an increase in domestic interest rates, a greater portion of our customers may not be able to pay their bills on a 
timely basis, which would increase our provision for doubtful accounts and adversely affect our financial condition and results of 
operations. 

We are dependent on key personnel and the ability to hire and retain additional personnel. 

We believe that our success will depend on the continued services of our senior management team and other key personnel. Our 
management team is comprised of highly qualified professionals, with extensive experience in the telecommunications industry. The 
loss of the services of any of our senior management team or other key employees could adversely affect our business, financial 
condition and results of operations. We also depend on the ability of our senior management and key personnel to work effectively as a 
team. 

Our future success also depends on our ability to identify, attract, hire, train, retain and motivate highly skilled technical, 

managerial, sales and marketing personnel. Competition for such personnel is intense, and we cannot guarantee that we will 
successfully attract, assimilate or retain a sufficient number of qualified personnel. Failure to retain and attract the necessary technical, 
managerial, sales and marketing and administrative personnel could adversely affect our business, financial condition and results of 
operations. 

Risks Relating to Our Brazilian Operations 

Our Residential Services business faces competition from mobile services and other fixed-line service providers, which may adversely 
affect our revenues and margins. 

Our Residential Services business, which provides local and long-distance fixed-line voice, fixed-line data, or broadband, and 

subscription television, or Pay-TV, services to our residential customers, as well as bundles of these services together with mobile 
services, faces competition from: 

•

•

mobile services, as reductions in interconnection tariffs, which have led to more robust mobile package offerings, have 
driven the traffic migration trend of fixed-to-mobile substitution; 

other fixed-line voice service providers, primarily (1) Claro S.A. (a subsidiary of América Móvil S.A.B. de C.V., or América 
Móvil, one of the leading telecommunications service providers in Latin America), or Claro, which markets its fixed-line 
voice services under the brand name “Embratel,” and (2) Telefônica Brasil S.A. (a subsidiary of Telefónica S.A.), or 
Telefônica Brasil, the largest telecommunications operator in Brazil);

service (including the number fixed lines provided to our Business-to-Business, or B2B, customers) in our service areas (all of Brazil 
other than the state of São Paulo) declined from 27.7 million to 12.9 million. As of December 31, 2017, based on information available 
from ANATEL, (1) we had a market share of 54.1% of the total fixed lines in service in Region I of Brazil and a market share of 50.1% 
of the total fixed lines in service in Region II of Brazil (in each case, including the fixed lines provided to our B2B customers); (2) 
Claro had a market share of 24.9% of the total fixed lines in service in Region I and a market share of 19.2% of the total fixed lines in 
service in Region II; and (3) Telefônica Brasil had a market share of 13.7% of the total fixed lines in service in Region I and a market 
share of 25.7% of the total fixed lines in service in Region II. 

As a result of competition from mobile services, we expect (1) the number of our fixed lines in service to experience a slow 
decline, as some of our customers eliminate their fixed-line services in favor of mobile services, and (2) the use of existing fixed lines 
for making voice calls to decline, as customers replace fixed-line calls in favor of calls on mobile phones as a result of the emergence of 
“all-net” plans, which allow a customer to make calls to any fixed-line or mobile device of any operator for a flat monthly fee. The rate 
at which the number of fixed lines in service in our service areas, a large majority of which are used by our residential customers, may 
decline depends on many factors beyond our control, such as economic, social, technological and other developments in Brazil. Despite 
the recent deceleration of fixed line disconnections, because we derive a significant portion of our net operating revenue from our 
Residential Services business, the reduction in the number of our fixed lines in service has negatively affected and is likely to continue 
to negatively affect our net operating revenue and margins. 

Our broadband services in Brazil face strong competition from Claro and Telefônica Brasil, which had market shares of 24.4% 

and 16.7%, respectively, for broadband services in Regions I and II of Brazil as of December 31, 2017, according to data from 
ANATEL. As of December 31, 2017, we had a market share of 33.4% for broadband services in Regions I and II of Brazil, according to 
data from ANATEL. Claro provides local fixed-line services to residential customers through its cable network in the portions of 
Regions I and II where it provides cable television and broadband services under the “Net” brand. Telefônica Brasil provides local 
fixed-line services through its own network and the assets it acquired from Vivendi S.A. when it acquired GVT Participações S.A. in 
2015. The primary drivers of competition in the broadband industry are speed and price, with discounts typically offered in the form of 
bundled services. Claro and Telefônica Brasil each offer broadband services at higher speeds than ours and both offer integrated voice, 
broadband and subscription television services, typically as bundles, to the residential services market through a single network 
infrastructure. Future offerings by our competitors that are aggressively priced or that offer additional services could have an adverse 
effect on our net operating revenue and our results of operations. 

The primary providers of Pay-TV services in the regions in which we provide residential services are SKY, which provides 
direct-to-home, or DTH, service, and Claro, which provides DTH service under the “Claro TV” brand and Pay-TV services using 
coaxial cable under the “Net” brand. We offer DTH services throughout the regions in which we provide residential services. Future 
changes in satellite technology may result in one of our competitors utilizing new satellites for DTH services that have higher capacities 
or better quality of service, which could adversely affect our net operating revenue and may adversely affect our results of operations. 

Our primary competitors for residential services, Claro and Telefônica Brasil, are each controlled by multinational companies that 

may have more significant financial and marketing resources, and greater abilities to access capital on a timely basis and on more 
favorable terms, than our company. In addition, we compete in our service areas with smaller companies that have been authorized by 
ANATEL to provide local fixed-line services. Increased competition from these small, regional companies may require us to increase 
our marketing expenses and our capital expenditures, which would lead to a decrease in our profitability. For a more information about 
our competition in the residential services market in Brazil, see “Item 4: Information on the Company—Competition—Residential 
Services.” 

Our Personal Mobility Services business faces strong competition from fixed-line service providers other mobile services providers and 
internet data providers, which may adversely affect our revenues and margins. 

The mobile services market in Brazil is extremely competitive. Our Personal Mobility Services business, which provides post-paid 

and pre-paid mobile voice services and post-paid and pre-paid mobile data communications services, faces competition from large 
competitors such as (1) TIM Participações S.A., or TIM, (2) Claro and (3) Telefônica Brasil, which markets its mobile services under 
the brand name “Vivo.” As of December 31, 2017, based on information regarding the total number of subscribers as of that date 
available from ANATEL, we had a market share of 16.5% of the total number of mobile subscribers (including subscribers in our B2B 
Services business), ranking behind Telefônica Brasil with 31.7%, Claro with 25.0% and TIM with 24.8%. Telefônica Brasil, Claro and 
TIM are each controlled by multinational companies that may have more significant financial and marketing resources, and greater 
abilities to access capital on a timely basis and on more favorable terms, than our company.

Our ability to generate revenues from our Personal Mobility Services business depends on our ability to continue to maintain or 

increase the average revenue per unit, or ARPU, generated by our customer base, retain or increase the size of our customer base, 
improve the perception of the quality of our services and encourage the migration of our customers to our UMTS (Universal Mobile 
Telecommunications System), or 3G, and our LTE (Long Term Evolution), or 4G, networks through our offers of attractive data 
packages that take advantage of the structural shift from voice to data usage. The recent trend towards SIM card consolidation, 
reversing the trend of customers using multiple SIM cards to participate in on-net calling plans and the demand for more aggressive 
data packages in the pre-paid market may result in a decline in the size of our customer base. The increased use of instant internet 
messaging and Voice over Internet Protocol, or VoIP, services on smartphone applications such as WhatsApp may result in a migration 
from voice to data services, which could have an adverse effect on the size and profitability of our customer base. Acquiring each 
additional personal mobility customer entails costs, including sales commissions and marketing costs. Recovering these costs depends 
on our ability to retain such customers. Therefore, high rates of customer churn could have a material adverse effect on the profitability 
of our Personal Mobility Services business. During 2017 and 2016, the average monthly churn rate of our Personal Mobility Services 
business was 4.1% and 4.4% per month, respectively. 

We have experienced increased pressure to reduce our mobile rates in response to pricing competition. This pricing competition 

has taken the form unlimited voice plans or special promotional packages, which may include, among other things, traffic usage 
promotions. We no longer offer handset subsidies for new customers, and competing with the service plans and promotions offered by 
our competitors may cause an increase in our marketing expenses and customer-acquisition costs, which has adversely affected our 
results of operations during some periods in the past and could continue to adversely affect our results of operations. Our inability to 
compete effectively with these packages could result in our loss of market share and adversely affect our net operating revenue and 
profitability. For more information about our competition in the personal mobility services market in Brazil, see “Item 4: Information 
on the Company—Competition—Personal Mobility Services.” 

Our B2B Services business faces strong competition from other mobile, fixed-line and information technology services providers, which 
may adversely affect our revenues and margins. 

Our B2B Services business provides a la carte and bundled fixed-line voice and data services, mobile voice and data services and 

information technology services to our small- and medium-sized enterprise, or SME, customers and our corporate (including 
government) customers, as well as interconnection, network usage and traffic transportation services to other telecommunications 
providers, which we refer to as our wholesale business. The competition risks relating to the fixed-line and mobile services we provide 
to our SME and corporate customers are similar to those relating to the fixed-line and mobile services we provide to our residential and 
personal mobility customers, respectively. 

The Brazilian recession has had a significant negative effect on our operating revenue and margins as SMEs generally, including 

our customers, have reduced the size of their businesses and in some cases ceased operations, and a number of our Corporate customers 
have reduced their telecommunications spending as part of their overall cost-cutting efforts. Because we derive a significant portion of 
our net operating revenue from our B2B Services business, the loss of a significant number of SME and corporate customers would 
adversely affect our net operating revenue and may adversely affect our results of operations. For more information about our 
competition in the B2B market in Brazil, see “Item 4: Information on the Company—Operations in Brazil—Competition—B2B 
Services.” 

Our long-distance services in Brazil face significant competition, which may adversely affect our revenues. 

In Brazil, unlike in the United States and elsewhere, a caller chooses its preferred long-distance carrier for each long-distance call, 

whether originated from a fixed-line telephone or a mobile handset, by dialing such carrier’s long-distance carrier selection code 
(Código de Seleção de Prestadora). The long-distance services market in Brazil has become less competitive as a result of ongoing 
reductions in the interconnection rates, as mandated by ANATEL. The proliferation of all-net service plans, particularly for mobile 
services, offers unlimited long-distance calls and data combination plans that have reduced the relevance of long-distance services for 
mobile services. As a result, competition for long-distance services in Brazil is limited to fixed-line voice services. We compete with 
Telefônica Brasil, which is the incumbent fixed-line service provider in the State of São Paulo. Competition in the Brazilian fixed-line 
long-distance market may require us to increase our marketing expenses and/or provide services at lower rates than those we currently 
expect to charge for such services. Competition in the Brazilian fixed-line long-distance market has had and could continue to have a 
material adverse effect on our revenues and margins.

The Brazilian telecommunications industry is highly regulated. Changes to these regulations have and may continue to adversely 
impact our business. 

The Brazilian telecommunications industry is highly regulated by ANATEL. ANATEL regulates, among other things, rates, 
quality of service and universal service goals, as well as competition among telecommunications service providers. Changes in laws and 
regulations, grants of new concessions, authorizations or licenses or the imposition of additional universal service obligations, among 
other factors, may adversely affect our business, financial condition and results of operations. For more information, see “Item 4. 
Regulation of the Brazilian Telecommunications Industry.” 

For example, in November 2012, ANATEL approved the General Plan on Competition Targets (Plano Geral de Metas de 
Competição), which includes criteria for the evaluation of telecommunications providers to determine which providers have significant 
market power, regulations applicable to the wholesale markets for trunk lines, backhaul, access to internet backbone and 
interconnection services, and regulations related to partial unbundling and/or full unbundling of the local fixed-line networks of public 
regime service providers. For more information, see “Item 4. Information on the Company—Regulation of the Brazilian 
Telecommunications Industry—Other Regulatory Matters—General Plan on Competition Targets.” We have been classified by 
ANATEL as a company with significant market power in certain markets, as a result of which we are subject to increased regulation in 
areas such as fixed-line and mobile infrastructure sharing and mobile interconnection rates. In 2014 ANATEL approved rules under 
which interconnection rates we are able to charge for the use of our mobile networks would be reduced between 2016 and 2019. As a 
result, the mobile interconnection rates for Regions I, II and III declined by 47.1%, 47.7% and 39.2%, respectively, in each of February 
2017 and 2018, and they will decline by the same percentages in February 2019. ANATEL has also set the interconnections rates we are 
able to charge for the use of our fixed-line networks, which have declined between 20.9% and 57.3% in each of February 2017 and 
2018 and will continue to decline by the same percentages in February 2019. For more information, see “Item 4. Information on the 
Company—Rates—Network Usage (Interconnection) Rates.” These regulations have had and will continue to have adverse effects on 
our revenues, although as a result of reductions in our costs and expenses for these services that we acquire from other 
telecommunications providers, we cannot predict with certainty the effects that these regulations will have on our results of operations. 

In December 2016, legislation was introduced in the Brazilian Congress, which we refer to as PLC 79, to substantially amend 
certain features of the current regulatory framework of the Brazilian telecommunications industry. For more information about PLC 79, 
see “Item 4. Information on the Company—Regulation of the Brazilian Telecommunications Industry—Concessions and 
Authorizations—Other Regulatory Matters—New Regulatory Framework.” PLC 79 has faced political gridlock in the Brazilian 
Congress and has not yet been passed, and we cannot predict whether this legislation will ultimately be adopted by the Brazilian 
Congress and executed by the President or will be adopted as proposed. Furthermore, should this legislation be adopted, many of its 
provisions would only have effects on our business following a rule-making procedure by ANATEL to implement the modifications to 
the regulatory scheme. We cannot predict the form of these new regulations or the time required for ANATEL to propose or adopt these 
regulations. Therefore, we unable to predict with any certainty the effects of this legislation on our company, if adopted. 

We cannot predict whether ANATEL, the Brazilian Ministry of Communications (Ministério das Comunicações) or the Brazilian 

government will adopt these or other telecommunications sector policies in the future or the consequences of such policies on our 
business or the business of our competitors. In the event that any modification of the regulatory scheme or new regulations applicable to 
our company are adopted that increase the costs of compliance to our company, whether through capital expenditure requirements, 
increased service requirements, increased costs for renewal of our authorizations and licenses, increased exposure to regulatory 
penalties or otherwise, these modifications and regulations could have a material adverse effect on our business, financial condition and 
results of operations. 

Our local fixed-line and domestic long-distance concession agreements in Brazil are subject to periodic modifications by ANATEL and 
we cannot assure you that the modifications to these concession agreements will not have adverse effects on our company. 

We provide fixed-line telecommunications services in our Brazilian service areas pursuant to concession agreements with the 
Brazilian government. These concession agreements expire on December 31, 2025, and may be amended by the parties every five years 
prior to the expiration date. In connection with each five-year amendment, ANATEL has the right, following public consultations, to 
impose new terms and conditions in response to changes in technology, competition in the marketplace and domestic and international 
economic conditions.

Our obligations under our concession agreements may be subject to revision in connection with each future amendment. Our 
concession agreements were last amended in 2011. In 2014, ANATEL held a public comment period for the 2015 revision of the terms 
of our concession agreements and met regularly with us throughout 2015 to discuss possible amendments, and in 2016 the Brazilian 
Ministry of Communications issued a decree addressing guidelines for the establishment of a new regulatory framework for 
telecommunications, in line with the provisions of PLC 79. Despite these efforts, our concession agreements have not yet been 
amended, as a result of the Brazilian Congress’s failure to date to pass PLC 79, passage of which is required to provide the necessary 
legal authority for ANATEL to implement the proposed changes to our concession agreements. Further discussions regarding 
amendments to our concession agreements have halted pending resolution of PLC 79. Under their existing terms, our concession 
agreements may be amended by December 2020 at the latest. If PLC 79 is not passed, our concession agreements will expire in 2025 
without the possibility of renewal. For more information about our concession agreements, see “Item 4. Information on the 
Company—Concessions, Authorizations and Licenses—Fixed-Line and Domestic Long-Distance Services Concession Agreements.” 

In connection with the consideration of revisions to the concession agreements under the public regime, in January 2017, 

ANATEL proposed revisions to the terms of the General Plan of Grants (Plano Geral de Outorgas), in line with the provisions of PLC 
79. However, as a result of the legislative gridlock faced by PLC 79, ANATEL has halted implementation of the General Plan of 
Grants. For more information about PLC 79 and ANATEL’s proposed revisions to the terms of the General Plan of Grants, see “Item 4. 
Information on the Company—Regulation of the Brazilian Telecommunications Industry—Other Regulatory Matters—New Regulatory 
Framework.” 

We cannot assure you that any future amendments to our concession agreements or the General Plan of Grants will not impose 

requirements on our company that will require us to undertake significant capital expenditures or will not modify the rate-setting 
procedures applicable to us in a manner that will significantly reduce the net operating revenue that we generate from our Brazilian 
fixed-line businesses. If the amendments to our Brazilian concession agreements have these effects, our business, financial condition 
and results of operations could be materially adversely affected. 

Our local fixed-line and domestic long-distance concession agreements expire on December 31, 2025 and we cannot assure you that 
our bids for new concessions upon the expiration of our existing concessions will be successful or that the pending expiration of these 
concessions will not have adverse effects on our ability to finance our operations. 

Our concession agreements will expire on December 31, 2025. We expect the Brazilian government to offer new concessions in 

competitive auctions prior to the expiration of our existing concession agreements. We may participate in such auctions, but our 
existing fixed-line and domestic long-distance concession agreements will not entitle us to preferential treatment in these auctions. If we 
do not secure concessions for our existing service areas in any future auctions, or if such concessions are on less favorable terms than 
our current concessions, our business, financial condition and results of operations would be materially adversely affected. In addition, 
based on the current scheduled expiration of our concession agreements and the uncertainty that the terms of these concessions will be 
extended, investors may be unwilling to make investments in our company on terms that are attractive to our company, or at all. Our 
inability to raise capital in the equity or debt markets on favorable terms, or at all, could have a materially adverse effect on our 
business, financial condition and results of operations. 

Our local fixed-line and domestic long-distance concession agreements in Brazil, as well as our authorizations to provide personal 
mobile services in Brazil, contain certain obligations, and our failure to comply with these obligations may result in various fines and 
penalties being imposed on us by ANATEL. 

Our local fixed-line and domestic long-distance concession agreements in Brazil contain terms reflecting the General Plan on 
Universal Service Goals (Plano Geral de Metas de Universalização), the General Plan on Quality Goals (Plano Geral de Metas de 
Qualidade) and other regulations adopted by ANATEL, the terms of which could affect our financial condition and results of 
operations. Our local fixed-line concession agreements in Brazil also require us to meet certain network expansion, quality of service 
and modernization obligations in each of the Brazilian states in our service areas. In the event of noncompliance with ANATEL targets 
in any one of these states, ANATEL can establish a deadline for achieving the targeted level of such service, impose penalties and, in 
extreme situations, terminate the applicable concession agreement for noncompliance with our quality and universal service obligations. 
See “Item 4: Information on the Company—Regulation of the Brazilian Telecommunications Industry—Regulation of Fixed-Line 
Services.” 

In addition, our authorizations to provide personal mobile services contain certain obligations requiring us to meet network scope 

and quality of service targets. If we fail to meet these obligations, we may be fined by ANATEL until we are in full compliance with 
our obligations and, in extreme circumstances, our authorizations could be revoked by ANATEL. See “Item 4. Information on the 
Company—Regulation of the Brazilian Telecommunications Industry—Regulation of Mobile Services—Obligations of Personal 
Mobile Services Providers.”

On an almost weekly basis, we receive inquiries from ANATEL requiring information from us on our compliance with the various 
service obligations imposed on us by our concession agreements. If we are unable to respond satisfactorily to those inquiries or comply 
with our service obligations under our concession agreements, ANATEL may commence administrative proceedings in connection with 
such noncompliance. We have received numerous notices of commencement of administrative proceedings from ANATEL, mostly due 
to our inability to achieve certain targets established in the General Plan on Quality Goals and the General Plan on Universal Service 
Goals. 

At the time that ANATEL notifies us it believes that we have failed to comply with our obligations, we evaluate the claim and, 

based on our assessment of the probability of loss relating to that claim, may establish a provision. We vigorously contest a substantial 
number of the assessments made against us. As a result of the commencement of the RJ Proceedings, our contingencies related to 
claims of ANATEL were reclassified liabilities subject to compromise and were measure as required by ASC 852. As of December 31, 
2017 our prepetition liabilities subject to compromise included R$9,334 million related with claims of ANATEL. By operation of the 
RJ Plan and the Brazilian Confirmation Order (provided that no stay or appeal of the Brazilian Confirmation Order results in a change 
of the Brazilian Confirmation Date), the claim for these contingent obligations has been novated and discharged under Brazilian law 
and ANATEL is entitled only to receive the recovery set forth in the RJ Plan in exchange for these contingent claims in accordance with 
the terms and conditions of the RJ Plan. For more information regarding the recoveries to which ANATEL is entitled under the RJ Plan, 
see “Item 5. Operating and Financial Review and Prospects—Liabilities Subject to Compromise—Civil Contingencies – ANATEL.” 

We may be unable to implement our plans to expand and enhance our existing networks in Brazil in a timely manner or without 
unanticipated costs, which could hinder or prevent the successful implementation of our business plan and result in revenues and net 
income being less than expected. 

Our ability to achieve our strategic objectives depends in large part on the successful, timely and cost-effective implementation of 

our plans to expand and enhance our networks in Brazil. Factors that could affect this implementation include: 

•

•

•

•

•

our ability to generate cash flow or to obtain future financing necessary to implement our projects; 

delays in the delivery of telecommunications equipment by our vendors; 

the failure of the telecommunications equipment supplied by our vendors to comply with the expected capabilities; 

the failure to obtain licenses necessary for our projects; and 

delays resulting from the failure of third-party suppliers or contractors to meet their obligations in a timely and cost-effective 
manner. 

Although we believe that our cost estimates and implementation schedule are reasonable, we cannot assure you that the actual 

costs or time required to complete the implementation of these projects will not substantially exceed our current estimates. Any 
significant cost overrun or delay could hinder or prevent the successful implementation of our business plan and result in revenues and 
net income being less than expected. 

Certain key inputs are subject to risks related to importation, and we acquire other key inputs from a limited number of domestic 
suppliers, which may further limit our ability to acquire such inputs in a timely and cost effective manner. 

The high growth in data markets in general and broadband in particular may result in a limited supply of equipment essential for 

the provision of such services, such as data transmission equipment and modems. The restrictions on the number of manufacturers 
imposed by the Brazilian government for certain inputs, mainly data transmission equipment and modems, and the geographical 
locations of non-Brazilian manufacturers of these inputs, pose certain risks, including: 

•

•

•

vulnerability to currency fluctuations in cases where inputs are imported and paid for with U.S. dollars, Euros or other 
non-Brazilian currency; 

difficulties in managing inventory due to an inability to accurately forecast the domestic availability of certain inputs; and 

the imposition of customs or other duties on key inputs that are imported. 

If any of these risks materialize, they may result in our inability to provide services to our customers in a timely manner or may 

affect the prices of our services, which may have an adverse effect on our business, financial condition and results of operations.

We make investments based on demand forecasts that may become inaccurate due to economic volatility and may result in revenues 
that lower than expected. 

We make certain investments, such as the procurement of materials and the development of physical sites, based on our forecasts 
of the amount of demand that customers will have for our services at a later date (generally several months later). However, any major 
changes in the Brazilian economic scenario may affect this demand and therefore our forecasts may turn out to be inaccurate. For 
example, economic crises may restrict credit to the population, and uncertainties relating to employment may result in a delay in the 
decision to acquire new products or services. As a result, it is possible that we may make larger investments based on demand forecasts 
than were necessary given actual demand at the relevant time, which may directly affect our cash flow.

Furthermore, improvements in economic conditions may have the opposite effect. For example, an increase in demand not 
accompanied by our investment in improved infrastructure may result in a possible loss of opportunity to increase our revenue or result 
in the degradation of the quality of our services. 

We may be unable to respond to the recent trend towards consolidation in the Brazilian telecommunications market. 

The Brazilian telecommunications market has been subject to consolidation. Mergers and acquisitions may change market 
dynamics, create competitive pressures, force small competitors to find partners and impact our financial condition; and may require us 
to adjust our operations, marketing strategies (including promotions), and product portfolio. For example, in March 2015, Telefónica 
S.A. acquired from Vivendi S.A., all of the shares of GVT Participações S.A., the controlling shareholder of Global Village Telecom 
S.A. This acquisition increased Telefónica’s share of the Brazilian telecommunications market, and we believe such trend is likely to 
continue in the industry as players continue to consolidate. Additional joint ventures, mergers and acquisitions among 
telecommunications service providers are possible in the future. If such consolidation occurs, it may result in increased competition 
within our market. We may be unable to adequately respond to pricing pressures resulting from consolidation in our market, adversely 
affecting our business, financial condition and results of operations. We may also consider engaging in merger or acquisition activity in 
response to changes in the competitive environment, which could divert resources away from other aspects of our business. 

Companies in the Brazilian telecommunication industry, including us, may be harmed by restrictions regarding the installation of new 
antennas for mobile services. 

Currently, there are approximately 250 municipal laws in Brazil that limit the installation of new antennas for mobile service, 
which has been a barrier to the expansion of mobile networks. Those laws are meant to regulate issues related to zoning and the alleged 
effects of the radiation and radiofrequencies of the antennas. The federal law, that establishes new guidelines to create a consolidated 
plan for the installation of antennas was approved in 2015, however, it is still pending specific regulation. Despite the federal initiative, 
as long as the municipal laws remain unchanged, the risk of noncompliance with regulations and of having services of limited quality in 
certain areas continues to exist, which could materially and adversely affect our business, results of operations and financial condition. 

Additional antenna installation is also limited as a result of concerns that radio frequency emissions from base stations may cause 

health problems. See “—Risk Factors Relating to the Telecommunications Industry—The mobile telecommunications industry and 
participants in this industry, including us, may be required to adopt an extensive program of field measurements of radio frequency 
emissions and be subject to further regulation and/or claims based on concerns regarding potential health problems and interfere with 
medical devices.

Our commitment to meet the obligations of our Brazilian employees’ pension plans, managed by Fundação Sistel de Seguridade Social 
and Fundação Atlântico de Seguridade Social may be higher than what is currently anticipated, and therefore, we may be required to 
make additional contributions of resources to these pension plans or to record liabilities or expenses that are higher than currently 
recorded. 

As sponsors of certain private employee pension plans in Brazil, which are managed by Fundação Sistel de Seguridade Social, or 

Sistel, and Fundação Atlântico de Seguridade Social, or FATL, our subsidiaries cover the actuarial deficits of these pension benefit 
plans, which provide guaranteed benefits to our retirees in Brazil and guaranteed future benefits to our current Brazilian employees at 
the time of their retirement. As of December 31, 2017 and 2016, our Brazilian pension benefit plans had an aggregate deficit of R$632 
million and R$560 million, respectively. Our commitment to meet these deficit obligations may be higher than we currently anticipate, 
and we may be required to make additional contributions or record liabilities or expenses that are higher than we currently record, 
which may adversely affect our financial results. If the life expectancy of the beneficiaries should exceed the life expectancies included 
in the actuarial models, the level of our contributions to these plans could increase. If the managers of these plans should suffer losses 
on the investments of the assets of these plans, we would be required to make additional contributions to these plans in order for these 
plans to be able to provide the agreed benefits. Any increase in the level of our contributions to these plans as a result of an increase in 
life expectancy or a decline in investment returns could have a material adverse effect on our financial condition or results of 
operations. For a more detailed description of our Brazilian pension plans, see “Item 6. Directors, Senior Management and 
Employees—Employees—Employee Benefits—Pension Benefit Plans.” 

As a result of the RJ Proceedings, certain of our unfunded obligations under our post-retirement plans have been classified on our 

balance sheet as “Liabilities subject to compromise.” As of each of December 31, 2017 and 2016, the aggregate amount of our 
unfunded obligations under our post-retirement defined benefit plans recognized by the RJ Court was R$560 million, all of which 
related to claims of FATL. For more information, see “Item 5. Operating and Financial Review and Prospects—Liabilities Subject to 
Compromise—Pension Plans,” “Item 6. Directors, Senior Management and Employees—Employees—Employee Benefits—Pension 
Benefit Plans—Fundação Atlântico de Seguridade Social—BrTPREV Plan” and note 28 to our consolidated financial statements 
included in this annual report. 

Risks Relating to Our African and Asian Operations 

Any impairment of the fair market value at which we record our indirect investment in Unitel in our financial statements would have a 
material adverse effect on our financial condition and results of operations. 

As of December 31, 2017 and 2016, we recorded in our consolidated financial statements as assets held for sale of 
R$4,675 million and R$5,404 million, respectively, mainly relating to our interest in Unitel, including R$2,012 million and 
R$2,009 million, respectively, of accrued dividends owed to our company by Unitel and R$1,920 million and R$1,995 million, 
respectively, representing the fair market value of Africatel’s 25% interest in Unitel, and recorded as liabilities directly associated with 
assets held for sale of R$354 million and R$545 million, respectively, mainly relating to our interest in Unitel. 

The book value of our indirect investment in Unitel is subjected to testing for impairment when events or changes in 

circumstances indicate that the value of our indirect investment in Unitel may be lower than the fair market value at which we carry this 
investment. We recorded losses of R$267 million and R$1,090 million for the years ended December 31, 2017 and 2016, respectively, 
as a result of our review of the fair value of our investment in Unitel. Any further impairment of our indirect investment in Unitel may 
result in a material adverse effect on our financial condition and results of operations. 

We cannot assure you as to when PT Ventures will realize the accounts receivable recorded with respect to the declared and unpaid 
dividends owed to PT Ventures by Unitel or when PT Ventures will receive dividends that have been declared or that may be declared 
by Unitel in the future. 

Since November 2012, PT Ventures has not received any payments for outstanding amounts owed to it by Unitel with respect to 

dividends declared by Unitel for the fiscal years ended December 31, 2014, 2013, 2012 and 2011, and the extraordinary dividends 
declared by Unitel in November 2010 based on its 2005 results of operations and free reserves held in 2006 US$112.5 million (R$478.4 
million) with respect to fiscal year 2014, through 2009. Based on the dividends declared by Unitel for those fiscal years, PT Ventures is 
entitled to receive the total amounts of US$187.5 million (R$732.2 million) with respect to fiscal year 2013, US$190.0 million 
(R$742.0 million) with respect to fiscal year 2012, US$190.0 million (R$742.0 million) with respect to fiscal year 2011, and 
US$157.5 million (R$615.0 million) with respect to the dividends declared in 2010. As of the date of this annual report, PT Ventures 
has only received US$63.7 million (R$248.7 million) of its share of the dividends declared by Unitel in 2010, and has not received any 
amount in respect of dividends declared by Unitel with respect to fiscal years 2011, 2012, 2013 or 2014.

In addition, at a general meeting of the shareholders of Unitel held on May 13, 2015, the other shareholders discussed the financial 

statements as well as the payment of dividends with respect to fiscal year 2014. The other Unitel shareholders did not permit PT 
Ventures to attend and participate in this shareholders’ meeting alleging that they did not acknowledge PT Ventures as a Unitel 
shareholder. PT Ventures has received a copy of the minutes of this meeting, which indicate that Unitel declared dividends in the 
amount of US$490.0 million (R$1,913.5 million), of which PT Ventures’ share amounts to US$122.5 million (R$478.4 million). 

On June 12, 2015, PT Ventures filed a suit in the Provincial Courts of Luanda requesting the court to require Unitel to produce the 

final minutes of the May 13, 2015 general shareholders’ meeting and to annul all resolutions purportedly made at this meeting. Unitel 
filed its defense and a motion to dismiss this action on November 23, 2015, and PT Ventures filed its answer to Unitel’s motion on 
December 7, 2015. A preparatory hearing took place before the Civil and Administrative Division of the Luanda Provincial Court on 
May 30, 2016, in order to allow the parties to try and reach an immediate agreement. However, both parties reiterated their respective 
positions during the hearing and no settlement agreement was reached. On April 5, 2017, the court rendered its decision and voided all 
the resolutions taken during the May 13, 2015 Unitel General Meeting. At a general meeting of the shareholders of Unitel held on 
August 16, 2017, the other shareholders reapproved all the resolutions that had been declared null and void by the Angolan court, with 
the dissenting vote of PT Ventures. 

At a general meeting of the shareholders of Unitel held on July 26, 2017, the other shareholders of Unitel approved the allocation 

of the 2015 profits to free reserve and retained earnings accounts, with the dissenting vote of PT Ventures. 

On August 16, 2017, a general meeting of shareholders of Unitel was convened to resolve upon the allocation of the 2016 profits, 
among other issues. The management proposed not to pay any dividends to shareholders again. However, PT Ventures’ representative 
at the meeting claimed that, since the management proposal had not been disclosed to the shareholders in advance, the shareholders had 
not had the opportunity to properly assess the proposal and therefore any resolution about the subject would end up being null and void. 
The meeting was therefore suspended for a period of 45 days, but it has not been resumed as of the date of this annual report. 

Another general meeting of shareholders of Unitel has been called for May 29, 2018 to resume the discussions of some of the 
pending items in the agenda of the general meeting of August 16, 2017, including the allocation of the 2016 profits, as well as to resolve 
upon the financial statements for the fiscal year ended December 31, 2017 and the allocation of the 2017 profits, among other issues. 
Unitel’s management once again proposed not to pay any dividends to shareholders. 

On several occasions, PT Ventures has requested an explanation from Unitel about its failure to pay to PT Ventures its share of the 
declared dividends. As of the date of this annual report, PT Ventures has not received a satisfactory explanation regarding this failure to 
pay, nor has PT Ventures received reliable indications as to the expected timing of the payment of the accrued dividends. As a result, on 
October 20, 2015, PT Ventures filed a suit in the Provincial Courts of Luanda seeking payment of outstanding dividends for the fiscal 
years 2010 through 2013, together with interest thereon. As a result of our institution of this suit, in 2017 and 2016 we recognized 
provisions with respect to the unpaid dividends of US$45 million (R$150 million) and US$14 million (R$44 million), respectively. 

We cannot assure you that PT Ventures will be successful in these suits, as to the timing of the payment of the accrued dividends 

to our company, or whether we will be able to receive dividends that have been declared or that may be declared by Unitel in the future. 
Our inability to receive these dividends could have a material adverse impact on the fair value of our investment in Unitel, our financial 
position and our results of operations. 

The other shareholders of Unitel have claimed that they believe that Pharol’s sale of a minority interest in Africatel to our company did 
not comply with the Unitel shareholders’ agreement. 

The Unitel shareholders’ agreement provides a right of first refusal to the other shareholders of Unitel if any shareholder desires to 

transfer any or all of its shares of Unitel, other than transfers to certain affiliated companies. This agreement also provides that if any 
shareholder breaches a material obligation under the Unitel shareholders’ agreement, the other shareholders will have a right to 
purchase the breaching shareholder’s stake in Unitel at its net asset value.

On March 14, 2016, the other shareholders of Unitel initiated an arbitration proceeding against PT Ventures, claiming that 

Pharol’s sale of a minority interest in Africatel to our company did not comply with the Unitel shareholders’ agreement. The other 
shareholders of Unitel had previously made the same claim as a counterclaim in the arbitration initiated by PT Ventures on October 13, 
2015, but then withdrew that counterclaim. The arbitral tribunal was constituted on April 14, 2016. On May 19, 2016, the arbitration 
proceeding against PT Ventures initiated by the other shareholders of Unitel was consolidated with the arbitration initiated by PT 
Ventures on October 13, 2015. PT Ventures presented its statement of claim on October 14, 2016 and the other shareholders of Unitel 
presented their statement of defense and counterclaim on February 28, 2017. A hearing in the arbitration was held from February 7 to 
16, 2018, where each party presented its arguments and the factual witnesses and experts from each side were heard. We cannot predict 
the outcome of this proceeding. An adverse outcome in this proceeding could have a material adverse impact on our financial condition 
and results of operations. 

PT Ventures disputes the other shareholders’ interpretation of the relevant provisions of the Unitel shareholders’ agreement, and 
we believe that the relevant provisions of the Unitel shareholders’ agreement apply only to a transfer of Unitel shares by PT Ventures 
itself. We have been defending against the allegation by Unitel’s other shareholders vigorously. If a binding decision by the arbitral 
tribunal were rendered ruling in favor of the interpretation of the Unitel shareholders’ agreement proposed by the other Unitel 
shareholders, PT Ventures could be required to sell its interest in Unitel for a value significantly lower than the amount that we record 
in our financial statements with respect to our indirect investment in Unitel. The sale of PT Ventures’ interest in Unitel in these 
circumstances could have a material adverse impact on our financial condition and results of operations. 

For more information about this proceeding, see “Item 8. Financial Information—Legal Proceedings—Legal Proceedings Relating 

to Our Interest in Unitel.” 

The other shareholders of Unitel have prevented PT Ventures from exercising its rights to appoint the chief executive officer and a 
majority of the board of directors of Unitel. 

Under the Unitel shareholders’ agreement, PT Ventures is entitled to appoint three of the five members of Unitel’s board of 

directors and its chief executive officer. Under the Unitel shareholders’ agreement, the appointment of the chief executive officer of 
Unitel is subject to the approval of the holders of 75% of Unitel’s shares. However, the other shareholders of Unitel have failed to vote 
to elect the directors nominated by PT Ventures at Unitel’s shareholders’ meetings, and as a result, PT Ventures’ representation on 
Unitel’s board of directors was reduced. 

On July 22, 2014, the only member of Unitel’s board of directors that had been appointed by PT Ventures resigned from his 
position, and the other shareholders of Unitel have not permitted PT Ventures to appoint a replacement. In November 2014, the other 
shareholders of Unitel stated to PT Ventures that its rights as a shareholder of Unitel had been purportedly “suspended” in October 
2012, although these other shareholders have not indicated any legal basis for this alleged suspension. At a general shareholders’ 
meeting of Unitel held on December 15, 2014, an election of members of the board of directors of Unitel was held. At this meeting, 
Unitel’s other shareholders claimed that PT Ventures was not entitled to vote as a result of the alleged suspension of its rights as a 
shareholder of Unitel in October 2012, and they refused to elect the member nominated by PT Ventures to Unitel’s board of directors. 
As of the date of this annual report, no nominee of PT Ventures serves on the Unitel board of directors. 

On January 14, 2015, PT Ventures filed a petition against Unitel before the Provincial Courts of Luanda, seeking to challenge 

resolutions purportedly made in Unitel’s General Meeting on December 15, 2014. 

On October 13, 2015, PT Ventures initiated an arbitration proceeding against the other shareholders of Unitel as a result of the 

violation by those shareholders of a variety of provisions of the Unitel shareholders’ agreement, including the provisions entitling PT 
Ventures to nominate the majority of the members of the board of directors of Unitel and its chief executive officer. The arbitral 
tribunal was constituted on April 14, 2016. PT Ventures presented its statement of claim on October 14, 2016 and the other shareholders 
of Unitel presented their statement of defense and counterclaim on February 28, 2017. A hearing in the arbitration was held from 
February 7 to 16, 2018, where each party presented its arguments and the factual witnesses and experts from each side were heard. We 
cannot predict the outcome of this proceeding. An adverse outcome in this proceeding could have a material adverse impact on our 
financial condition and results of operations. For more information about this proceeding, see “Item 8. Financial Information—Legal 
Proceedings—Legal Proceedings Relating to Our Interest in Unitel.”

Unitel has granted loans to a related party and entered into a management contract with a third-party without the approval of PT 
Ventures. 

Under the Unitel shareholders’ agreement, the shareholders of Unitel and their affiliates are not permitted to enter into any 
contracts with Unitel unless the contracts are approved by a resolution of Unitel’s board of directors adopted by at least four members 
of its board of directors. As a result of the inability of PT Ventures to appoint members of the Unitel board of directors, PT Ventures is 
unable to effectively exercise its implied veto right over related party transactions of Unitel. 

Between May and October 2012, Unitel made disbursements to Unitel International Holdings B.V., or Unitel Holdings, of 

€178.9 million (R$760.4 million) and US$35.0 million (R$136.7 million) under a “Facility Agreement” entered into between Unitel and 
Unitel Holdings. Unitel Holdings is owned by Mrs. Isabel dos Santos, an indirect shareholder of Unitel and a member of the board of 
directors of Unitel. 

In September 2015, PT Ventures commenced litigation in the British Virgin Islands, or the BVI, against Vidatel, one of the other 

shareholders of Unitel, seeking a worldwide freezing order against Vidatel (prohibiting Vidatel from disposing of, dealing or 
diminishing the value of any of its assets (whether in the BVI or elsewhere)). In February 2016, the BVI court issued a judgment 
granting this freezing order against Vidatel pending the conclusion of the ICC arbitration brought by PT Ventures. In March 2018, the 
BVI court denied an application by Vidatel to set aside the worldwide freezing order. 

In March 2016, PT Ventures commenced litigation in the Netherlands against Unitel Holdings, Isabel dos Santos, Tokeyna 
Management Limited and Unitel’s chief executive officer as defendants, claiming that each of the defendants cooperated with and/or 
benefited from the misappropriation of funds from Unitel. The defendants in the Dutch litigation challenged the jurisdiction of the 
court, and in May 2017 the Dutch court denied the defendants’ objection and affirmed jurisdiction. The defendants have appealed that 
ruling and the matter is now before the Dutch court of appeal. 

We cannot assure you that we will be able to prevent Unitel from taking actions that should require the approval of the members 

of the Unitel board of directors nominated by PT Ventures, including approving related party transactions with the other shareholders of 
Unitel that we believe are detrimental to the financial condition and results of operations of Unitel. The use of the resources of Unitel in 
this manner could have a material adverse impact on the financial position and results of operations of Unitel and therefore the value of 
our investment in Unitel. 

On October 13, 2015, PT Ventures initiated an arbitration proceeding against the other shareholders of Unitel as a result of the 
violation by those shareholders of a variety of provisions of the Unitel shareholders’ agreement, including the provisions that would 
have entitled PT Ventures to veto these related party transactions. The arbitral tribunal was constituted on April 14, 2016. PT Ventures 
presented its statement of claim on October 14, 2016 and the other shareholders of Unitel presented their statement of defense and 
counterclaim on February 28, 2017. A hearing in the arbitration was held from February 7 to 16, 2018, where each party presented its 
arguments and the factual witnesses and experts from each side were heard. We cannot predict the outcome of this proceeding. An 
adverse outcome in this proceeding could have a material adverse impact on our financial condition and results of operations. For more 
information about this proceeding, see “Item 8. Financial Information—Legal Proceedings—Legal Proceedings Relating to Our Interest 
in Unitel.” 

The other shareholders of Unitel have attempted to dilute our indirect ownership of Unitel through a capital increase in which we could 
be technically unable to participate, and have called shareholders’ meetings at which they have indicated the desire to unilaterally 
amend the by-laws of Unitel and the Unitel shareholders’ agreement. 

At a general shareholders’ meeting of Unitel held on December 15, 2014, the other shareholders of Unitel voted to increase 

Unitel’s share capital and alter the nominal value of its shares. The details of this capital increase are obscure to us as they were not 
included in the prior notice for this meeting nor were they discussed in detail during this meeting. Additional details of this capital 
increase have been included in draft minutes of this meeting provided to PT Ventures and it appears that, although PT Ventures has 
determined to subscribe to its pro rata share of this capital increase to avoid dilution of its interest in Unitel, payment of the 
subscription price may be proposed under conditions that would not permit PT Ventures to obtain the necessary foreign exchange 
approvals prior to the date on which payment would be due. 

The agenda of this general shareholders’ meeting of Unitel included amendments to Unitel’s by-laws and purported amendments 

to Unitel shareholders’ agreement, in addition to other matters that may have been raised at the shareholders’ meeting itself, which 
included investments by Unitel in Zimbabwe and a study in order to implement a corporate reorganization of Unitel. We have not been 
provided of the details of the proposed by-law amendments nor of any purported amendments to the Unitel shareholders’ agreement. 
The December 15, 2014 meeting was suspended without any action taken on these items.

On January 14, 2015, PT Ventures filed a suit in the Provincial Courts of Luanda to annul all resolutions taken during the 

December 15, 2014 general shareholders’ meeting, including the approval of the Unitel capital increase, the approval of investments by 
Unitel in Zimbabwe, and a study in order to implement a corporate reorganization of Unitel. On March 24, 2016, the Civil and 
Administrative Division of the Luanda Provincial Court notified PT Ventures to attach new exhibits, which PT Ventures did May 5, 
2016. 

We note that there appears to be no legal authority for the other shareholders of Unitel to amend the Unitel shareholders’ 
agreement through actions taken at a general meeting of shareholders, as this agreement is an agreement among the parties thereto. 
Should the other shareholders approve actions detrimental to Unitel or our investment in Unitel, these actions could have a material 
adverse impact on the financial position and results of operations of Unitel and therefore the value of our investment in Unitel. 

Adverse political, economic and legal conditions in the African and Asian countries in which we have acquired investments may hinder 
our ability to receive dividends from our African and Asian subsidiaries and investments. 

The governments of many of the African and Asian countries in which we have investments have historically exercised, and 
continue to exercise, significant influence over their respective economies and legal systems. Countries in which we have investments 
may enact legal or regulatory measures that restrict the ability of our subsidiaries and investees to make dividend payments to us. 
Similarly, adverse political or economic conditions in these countries may hinder our ability to receive dividends from our subsidiaries 
and investees. Historically, Pharol has received dividends from the African and Asian subsidiaries and investees that we have acquired; 
however, a limitation on our ability to receive a material portion of those dividends could adversely affect our cash flows and liquidity. 

In addition, our investments in these regions are exposed to political and economic risks that include, but are not limited to, 

exchange rate and interest rate fluctuations, inflation and restrictive economic policies and regulatory risks that include, but are not 
limited to, the process for the renewal of licenses and the evolution of regulated retail and wholesale tariffs. In addition, our ventures in 
African and Asian markets face risks associated with increasing competition, including due to the entrance of new competitors and the 
rapid development of new technologies. 

The development of partnerships in these markets raises risks related to the ability of the partners to jointly operate the assets. Any 

inability of our company and our partners to operate these assets may have a negative impact on our strategy and all of these risks may 
have material effects on our results of operations. 

Risks Relating to Brazil 

The Brazilian government has exercised, and continues to exercise, significant influence over the Brazilian economy. This involvement, 
as well as Brazilian political and economic conditions, could adversely impact our business, results of operations and financial 
condition.

Oi is a Brazilian corporation, and a majority of our operations and customers are located in Brazil. Accordingly, our financial 
condition and results of operations are substantially dependent on Brazil’s economy. The Brazilian government frequently intervenes in 
the Brazilian economy and occasionally makes significant changes in policy and regulations. The Brazilian government’s actions to 
control inflation and implement macroeconomic policies have often involved increases in interest rates, wage and price controls, 
currency devaluations, blocking access to bank accounts, imposing capital controls and limits on imports, among other things. We do 
not have any control over, and are unable to predict, which measures or policies the Brazilian government may adopt in the future. Our 
business, results of operations and financial condition may be adversely affected by changes in policies or regulations, or by other 
factors such as: 

•

•

•

•

•

•

•

•

political instability; 

devaluations and other currency fluctuations; 

inflation; 

price instability; 

interest rates; 

liquidity of domestic capital and lending markets; 

energy shortages; 

exchange controls;

changes to the regulatory framework governing our industry; 

monetary policy; 

tax policy; and 

other political, diplomatic, social and economic developments in or affecting Brazil, including with respect to alleged 
unethical or illegal conduct of certain figures in the Brazilian government and legislators, which are currently under 
investigation. 

Uncertainty over whether possible changes in policies or rules affecting these or other factors may contribute to economic 
uncertainties in Brazil and to heightened volatility in the Brazilian securities markets and securities issued abroad by Brazilian issuers. 
The President of Brazil has considerable power to determine governmental policies and actions that relate to the Brazilian economy and, 
consequently, affect the operations and financial performance of businesses such as our company. We can offer no assurances that the 
policies that may be implemented by the Brazilian federal or state governments will not adversely affect our business, results of 
operations and financial condition. 

In addition, protests, strikes and corruption scandals have led to a fall in confidence and a political crisis. For example, Brazilian 

markets have been experiencing heightened volatility due to the uncertainties derived from the ongoing “Lava Jato” investigation, 
which is being conducted by the Office of the Brazilian Federal Prosecutor, and its impact on the Brazilian economy and political 
environment. Members of the Brazilian federal government and of the legislative branch, as well as senior officers of certain Brazilian 
private and state-owned companies, have faced allegations of political corruption. These government officials and senior officers 
allegedly accepted bribes by means of kickbacks on contracts granted by major state-owned companies to several infrastructure, oil and 
gas and construction companies. The profits of these kickbacks allegedly financed the political campaigns of the main political parties 
in Brazil that were unaccounted for or not publicly disclosed, as well as served to personally enrich the recipients of the bribery scheme. 
As a result of the ongoing “Lava Jato” investigation, a number of senior politicians, including congressman and officers of the major 
state-owned companies in Brazil resigned or have been arrested. The potential outcome of the “Lava Jato” investigation is uncertain, 
but it has already adversely affected the Brazilian markets and trading prices of securities issued by Brazilian issuers. We cannot predict 
whether the “Lava Jato” investigation will lead to further political and economic instability or whether new allegations against 
government officials or other companies in Brazil will arise in the future. 

Furthermore, on December 2, 2015, the Brazilian Congress opened impeachment proceedings against Brazilian President Dilma 
Rousseff for allegedly breaking federal budget laws during her re-election campaign in 2014. On May 12, 2016, the Brazilian Senate 
voted to begin its review of the impeachment proceedings against President Dilma Rousseff, who was suspended from office. After the 
legal and administrative process for the impeachment, Brazil’s Senate removed President Dilma Rousseff from office on August 31, 
2016 for infringing budgetary laws. Michel Temer, the former vice president, who had been acting President of Brazil following 
Ms. Rousseff’s suspension in May 2016, was sworn in by Senate to serve out the remainder of the presidential term until 2018. There 
was an ongoing proceeding before the Brazilian Higher Electoral Court (Tribunal Superior Eleitoral) alleging that the electoral alliance 
between Ms. Rousseff and Mr. Temer in the 2014 general election had violated campaign finance laws. On June 9, 2017, the Brazilian 
Higher Electoral Court absolved the electoral alliance, including President Temer of wrongdoing; however, he remains subject to 
heightened scrutiny due to the ongoing Lava Jato investigations. The resolution of the political and economic crisis in Brazil still 
depends on the outcome of the Lava Jato investigation and proceedings and approval of reforms that are expected to be promoted by the 
new president. In addition, the presidential election in Brazil is expected to occur in October 2018. The election may change 
government political policies and the elected administration may implement new policies. We cannot predict which policies the 
Brazilian government may adopt or change or the effect that any such policies might have on our business and on the Brazilian 
economy. Any such new policies or changes to current policies may have a material adverse effect on our business, results of operations 
and financial condition. 

Depreciation of the real may lead to substantial losses on our liabilities denominated in or indexed to foreign currencies.

During the four decades prior to 1999, the Brazilian Central Bank periodically devalued the Brazilian currency. Throughout this 

period, the Brazilian government implemented various economic plans and used various exchange rate policies, including sudden 
devaluations (such as daily and monthly adjustments), exchange controls, dual exchange rate markets and a floating exchange rate 
system. Since 1999, exchange rates have been set by the market. The exchange rate between the real and the U.S. dollar has varied 
significantly in recent years. For example, the real/U.S. dollar exchange rate increased from R$1.9554 per U.S. dollar on December 31, 
2000 to R$3.5333 on December 31, 2002. The real depreciated by 8.9% against the U.S. dollar during 2012, by 14.6% during 2013, by 
13.4% during 2014 and by 47.1% during 2015, appreciated by 16.5% in 2016 and depreciated by 1.5% in 2017. In addition, the real 
depreciated by 10.7% against the Euro during 2012, by 19.7% during 2013, was substantially unchanged during 2014, depreciated by 
31.7% in 2015, appreciated by 19.1% in 2016 and depreciated by 15.4% in 2017.

As of December 31, 2017 and 2016, R$36,557 million and R$36,693 million, respectively, of our loans and financing classified as 
liabilities subject to compromise was denominated in currencies other than the real, representing 74.4% and 74.5%, respectively, of our 
consolidated financial indebtedness. As a result of the commencement of the RJ Proceedings, we ceased recording exchange rate gains 
and losses with respect to these loans and financings. Following the implementation of the RJ Plan, we expect that our obligations under 
(1) our New Notes that will be issued to holders of bonds issued by Oi, Oi Coop and PTIF that are entitled to receive the Qualified 
Recovery described under “—Liabilities Subject to Compromise—Loans and Financing—Fixed Rate Notes,” (2) participations under 
the Non-Qualified Credit Agreement that will be available to holders of bonds issued by Oi, Oi Coop and PTIF that are entitled to 
receive the Non-Qualified Recovery described under “Item 5. Operating and Financial Review and Prospects—Liabilities Subject to 
Compromise—Loans and Financing—Fixed Rate Notes,” (3) recoveries of creditors under our export credit agreements, and 
(4) recoveries under our bonds issued by Oi, Oi Coop and PTIF to holders of our U.S. dollar-denominated bonds issued by Oi and Oi 
Coop that are not entitled to receive the Qualified Recovery or the Non-Qualified Recovery, will be denominated in U.S. dollars and 
will accrue interest at fixed-rates in U.S. dollars. 

When the real depreciates against foreign currencies, we incur losses on our liabilities denominated in or indexed to foreign 
currencies, such as our U.S. dollar-denominated and Euro-denominated long-term debt and foreign currency loans, and we incur gains 
on our monetary assets denominated in or indexed to foreign currencies, as the liabilities and assets are translated into reais. If 
significant depreciation of the real were to occur when the value of such liabilities significantly exceeds the value of such assets, 
including any financial instruments entered into for hedging purposes, we could incur significant losses, even if the value of those assets 
and liabilities has not changed in their original currency. In addition, a significant depreciation in the real could adversely affect our 
ability to meet certain of our payment obligations. A failure to meet certain of our payment obligations could trigger a default under 
certain financial covenants in our debt instruments, which could have a material adverse effect on our business and results of operations. 
Historically, we have maintained currency swaps and non-deliverable forwards to manage our exposure to most of our foreign currency 
debt. During 2017 and 2016, in connection with our consideration of potential plans to restructure our indebtedness, we did not roll over 
our non-deliverable forwards and selectively settled several of our long-term currency swaps. As a result, our exposure to foreign 
currency fluctuations has increased substantially. As an effect of the approval and confirmation of the RJ Plan, we expect to restructure 
our indebtedness in a manner that the increased exposure to foreign currency fluctuations to be temporary. In the event that these 
expectations are not met, the effects of foreign currency fluctuations on our debt instruments could have a material adverse effect on our 
financial condition and results of operations. 

A portion of our capital expenditures and operating leases require us to acquire assets or use third-party assets at prices 

denominated in or linked to foreign currencies, some of which are financed by liabilities denominated in foreign currencies, principally 
the U.S. dollar and the Euro. We generally do not hedge exposures relating to our capital expenditures or operating expenses against 
risks related to movements of the real against foreign currencies. To the extent that the value of the real decreases relative to the U.S. 
dollar or the Euro, it becomes more costly for us to purchase these assets or services, which could adversely affect our business and 
financial performance. 

Depreciation of the real relative to the U.S. dollar could create additional inflationary pressures in Brazil by increasing the price of 

imported products and requiring recessionary government policies, including tighter monetary policy. On the other hand, appreciation 
of the real against the U.S. dollar may lead to a deterioration of the country’s current account and balance of payments, as well as to a 
dampening of export-driven growth. 

If Brazil experiences substantial inflation in the future, our margins and our ability to access foreign financial markets may be reduced. 
Government measures to curb inflation may have adverse effects on the Brazilian economy, the Brazilian securities market and our 
business and results of operations. 

Brazil has in the past experienced extremely high rates of inflation, with annual rates of inflation reaching as high as 2,708% in 
1993 and 1,093% in 1994. Inflation and some of the Brazilian government’s measures taken in an attempt to curb inflation have had 
significant negative effects on the Brazilian economy. 

Since the introduction of the real in 1994, Brazil’s inflation rate has been substantially lower than in previous periods. However, 
actions taken in an effort to control inflation, coupled with speculation about possible future governmental actions, have contributed to 
economic uncertainty in Brazil and heightened volatility in the Brazilian securities market. More recently, Brazil’s rates of inflation, as 
measured by the General Market Price Index — Internal Availability (Índice Geral de Preços — Disponibilidade Interna), or IGP-DI, 
published by Fundação Getúlio Vargas, or FGV, were 5.5% in 2013, 3.8% in 2014, 10.7% in 2015, 7.2% in 2016 and (0.42)% in 2017. 
According to the Broad Consumer Price Index (Índice Nacional de Preços ao Consumidor Ampliado), or IPCA, published by the 
Brazilian Institute for Geography and Statistics (Instituto Brasileiro de Geografia e Estatística), or IBGE, the Brazilian consumer price 
inflation rates were 5.9% in 2013, 6.4% in 2014, 10.7% in 2015, 6.3% in 2016 and 3.0% in 2017.

If Brazil experiences substantial inflation in the future, our costs may increase and our operating and net margins may decrease. 

Although ANATEL regulations provide for annual price increases for most of our services in Brazil, such increases are linked to 
inflation indices, discounted by increases in our productivity. During periods of rapid increases in inflation, the price increases for our 
services may not be sufficient to cover our additional costs and we may be adversely affected by the lag in time between the incurrence 
of increased costs and the receipt of revenues resulting from the annual price increases. Inflationary pressures may also curtail our 
ability to access foreign financial markets and may lead to further government intervention in the economy, including the introduction 
of government policies that may adversely affect the overall performance of the Brazilian economy. 

Fluctuations in interest rates could increase the cost of servicing our debt and negatively affect our overall financial performance. 

Our financial expenses are affected by changes in the interest rates that apply to our floating rate debt. As of each of December 31, 

2017 and 2016, we had, among other consolidated debt obligations, R$15,870 million of loans and financings that were subject to 
variable interest rates, including: (1) R$4,982 million of loans and financings that were subject to the London Interbank Offered Rate, 
or LIBOR; (2) R$6,388 million of loans and financings and debentures that were subject to the Interbank Certificate of Deposit 
(Certificado de Depósito Interbancário), or CDI, rate, an interbank rate; (3) R$2,927 million of loans and financings and debentures 
that were subject to the Long-Term Interest Rate (Taxa de Juros de Longo Prazo), or TJLP, a long-term interest rate; and 
(4) R$1,573 million of loans and financings that were subject to the IPCA rate, an inflation index. 

The TJLP includes an inflation factor and is determined quarterly by the National Monetary Council (Conselho Monetário 
Nacional). In particular, the TJLP and the CDI rate have fluctuated significantly in the past in response to the expansion or contraction 
of the Brazilian economy, inflation, Brazilian government policies and other factors. For example, the CDI increased from 9.77% per 
annum as of December 31, 2013 to 11.57% per annum as of December 31, 2014, increased to 14.13% per annum as of December 31, 
2015, decreased to 13.63% per annum as of December 31, 2016 and decreased to 6.89% per annum as of December 31, 2017. 

As a result of the commencement of the RJ Proceedings, we ceased recording interest expenses on these loans and financings. By 

operation of the RJ Plan and the Brazilian Confirmation Order (provided that no stay or appeal of the Brazilian Confirmation Order 
results in a change of the Brazilian Confirmation Date), these loans and loans and financings have been novated and discharged under 
Brazilian law and creditors under these loans and financings are entitled only to receive the recoveries set forth in the RJ Plan in 
exchange for their claims in accordance with the terms and conditions of the RJ Plan. For more information regarding the recoveries to 
which creditors under our loans and financings are entitled under the RJ Plan, see “Item 5. Operating and Financial Review and 
Prospects—Liabilities Subject to Compromise—Loans and Financing.” 

Following the implementation of the RJ Plan, we expect that recoveries of creditors under our debentures, unsecured lines of 
credit and lessors under the lease contracts of Oi and Telemar relating to real property owned by Copart 4 and Copart 5 will accrue 
interest based on the CDI rate. As a result, following the implementation of the RJ Plan, inflation will increase our interest expenses and 
debt service obligations with respect to these recoveries. In addition, the RJ Plan permits us to seek to raise up to R$2.5 billion in the 
capital markets and seek to borrow up to R$2 billion under new export credit facilities, as described under “—Liquidity and Capital 
Resources.” This debt may accrue interest at floating rates in foreign currencies. Accordingly, we may incur interest expenses and 
foreign exchange gains and losses in connection with this new debt. A significant increase in any of these interest rates could adversely 
affect our financial expenses and negatively affect our overall financial performance. 

The market value of securities issued by Brazilian companies is influenced by the perception of risk in Brazil and other countries, which 
may have a negative effect on the trading price of Oi’s common shares, preferred shares and ADSs and may restrict our access to 
international capital markets. 

Economic and market conditions in other countries and regions, including the United States, the European Union and emerging 
market countries, may affect to varying degrees the market value of securities of Brazilian issuers. Although economic conditions in 
these countries and regions may differ significantly from economic conditions in Brazil, investors’ reactions to developments in these 
other countries may have an adverse effect on the market value of securities of Brazilian issuers, the availability of credit in Brazil and 
the amount of foreign investment in Brazil. Crises in the European Union, the United States and emerging market countries have at 
times resulted in significant outflows of funds from Brazil and may diminish investor interest in securities of Brazilian issuers, 
including our company. This could materially and adversely affect the market price of our securities, and could also make it more 
difficult for us to access the capital markets and finance our operations in the future on acceptable terms or at all.

Restrictions on the movement of capital out of Brazil may impair our ability to service certain debt obligations. 

Brazilian law provides that whenever there exists, or there is a serious risk of, a material imbalance in Brazil’s balance of 
payments, the Brazilian government may impose restrictions for a limited period of time on the remittance to foreign investors of the 
proceeds of their investments in Brazil as well as on the conversion of the real into foreign currencies. The Brazilian government 
imposed such a restriction on remittances for approximately six months in 1989 and early 1990. The Brazilian government may in the 
future restrict companies from paying amounts denominated in foreign currency or require that any such payment be made in reais. 
Many factors could affect the likelihood of the Brazilian government imposing such exchange control restrictions, including the extent 
of Brazil’s foreign currency reserves, the availability of sufficient foreign exchange on the date a payment is due, the size of Brazil’s 
debt service burden relative to the economy as a whole, and political constraints to which Brazil may be subject. There can be no 
certainty that the Brazilian government will not take such measures in the future. 

A more restrictive policy could increase the cost of servicing, and thereby reduce our ability to pay, our foreign currency-
denominated debt obligations and other liabilities. As of December 31, 2017 and 2016, our foreign-currency denominated debt was 
R$36,557 million and R$36,693 million, respectively, and represented 74.4% and 74.5%, respectively, of our consolidated 
indebtedness. If we fail to make payments under any of these restructured debt obligations, we will be in default under those 
obligations, which could reduce our liquidity as well as the market price of Oi’s common shares, preferred shares and ADSs. 

In addition, a more restrictive policy could hinder or prevent the Brazilian custodian of the common shares and preferred shares 

underlying Oi’s ADSs or holders who have exchanged Oi’s ADSs for the underlying common shares or preferred shares from 
converting dividends, distributions or the proceeds from any sale of such shares into U.S. dollars and remitting such U.S. dollars 
abroad. In such an event, the Brazilian custodian for Oi’s common shares and preferred shares will hold the reais that it cannot convert 
for the account of holders of Oi’s ADSs who have not been paid. Neither the custodian nor The Bank of New York Mellon, as 
depositary of Oi’s ADS programs, which we refer to as the depositary, will be required to invest the reais or be liable for any interest. 

Risks Relating to Oi’s Common Shares, Preferred Shares and ADSs 

Holders of Oi’s common shares, preferred shares or ADSs may not receive any dividends or interest on shareholders’ equity. 

According to Oi’s by-laws and the Brazilian Corporate Law, Oi must generally pay its shareholders at least 25% of Oi’s 

consolidated annual net income as dividends or interest on shareholders’ equity, as calculated and adjusted under Brazilian GAAP. This 
adjusted net income may be capitalized, used to absorb losses or otherwise retained as allowed under Brazilian GAAP and may not be 
available to be paid as dividends or interest on shareholders’ equity. Holders of Oi’s common shares or Common ADSs may not receive 
any dividends or interest on shareholders’ equity in any given year due to the dividend preference of Oi’s preferred shares. Additionally, 
the Brazilian Corporate Law allows a publicly traded company like Oi to suspend the mandatory distribution of dividends in any 
particular year if Oi’s board of directors informs Oi’s shareholders that such distributions would be inadvisable in view of Oi’s financial 
condition or cash availability. Holders of Oi’s preferred shares or Preferred ADSs may not receive any dividends or interest on 
shareholders’ equity in any given year if Oi’s board of directors makes such a determination or if our operations fail to generate net 
income. Holders of Oi’s preferred shares and preferred ADSs have not received dividend payments since October 11, 2013. Under the 
RJ Plan, Oi and the other RJ Debtors are prohibited from declaring or paying dividends, interest on shareholders’ equity or other forms 
of return on capital or making any other payment or distribution on or related to their shares (including any payment related to a merger 
or consolidation) until the sixth anniversary of the date of the Judicial Ratification of the RJ Plan, subject to certain exceptions, as 
described under “Item 8. Financial Information—Dividends and Dividend Policy.”

Holders of Oi’s ADSs may find it difficult to exercise their voting rights at Oi’s shareholders’ meetings. 

Under Brazilian law, only shareholders registered as such in Oi’s corporate books may attend Oi’s shareholders’ meetings. All 

common shares and preferred shares underlying Oi’s ADSs are registered in the name of the depositary. ADS holders may exercise the 
voting rights with respect to Oi’s common shares and the limited voting rights with respect to Oi’s preferred shares represented by Oi’s 
ADSs only in accordance with the deposit agreements relating to Oi’s ADSs. There are practical limitations upon the ability of the ADS 
holders to exercise their voting rights due to the additional steps involved in communicating with ADS holders. For example, Oi is 
required to publish a notice of Oi’s shareholders’ meetings in certain newspapers in Brazil. To the extent that holders of Oi’s common 
shares or preferred shares are entitled to vote at a shareholders’ meeting, they will be able to exercise their voting rights by attending the 
meeting in person or voting by proxy. By contrast, holders of the ADSs may receive notice of a shareholders’ meeting by mail from the 
depositary if Oi notifies the depositary of the shareholders’ meeting and request the depositary to inform ADS holders of the 
shareholders’ meeting. To exercise their voting rights, ADS holders must instruct the depositary on a timely basis. This noticed voting 
process will take longer for ADS holders than for holders of Oi’s common shares or preferred shares. If the depositary fails to receive 
timely voting instructions for all or part of Oi’s ADSs, the depositary will assume that the holders of those ADSs are instructing it to 
give a discretionary proxy to a person designated by us to vote their ADSs, except in limited circumstances. 

In the circumstances in which holders of Oi’s ADSs have voting rights, they may not receive the voting materials in time to 
instruct the depositary to vote Oi’s common shares or preferred shares underlying their ADSs. In addition, the depositary and its agents 
are not responsible for failing to carry out voting instructions of the holders of Oi’s ADSs or for the manner of carrying out those voting 
instructions. Accordingly, holders of Oi’s ADSs may not be able to exercise voting rights, and they will have no recourse if the 
common shares or preferred shares underlying their ADSs are not voted as requested. 

Holders of Oi’s common shares, preferred shares or ADSs in the United States may not be entitled to the same preemptive rights as 
Brazilian shareholders have, pursuant to Brazilian legislation, in the subscription of shares resulting from capital increases made by 
us. 

Under Brazilian law, if Oi issues new shares in exchange for cash or assets as part of a capital increase, subject to certain 
exceptions, Oi must grant its shareholders preemptive rights at the time of the subscription of shares, corresponding to their respective 
interest in Oi’s share capital, allowing them to maintain their existing shareholding percentage. Oi may not legally be permitted to allow 
holders of its common shares, preferred shares or ADSs in the United States to exercise any preemptive rights in any future capital 
increase unless (1) Oi files a registration statement for an offering of shares resulting from the capital increase with the U.S. Securities 
and Exchange Commission, or SEC, or (2) the offering of shares resulting from the capital increase qualifies for an exemption from the 
registration requirements of the Securities Act. At the time of any future capital increase, Oi will evaluate the costs and potential 
liabilities associated with filing a registration statement for an offering of shares with the SEC and any other factors that Oi considers 
important in determining whether to file such a registration statement. Oi cannot assure the holders of Oi’s common shares, preferred 
shares or ADSs in the United States that Oi will file a registration statement with the SEC to allow them to participate in any of Oi’s 
capital increases. As a result, the equity interest of such holders in Oi may be diluted. 

If holders of Oi’s ADSs exchange them for common shares or preferred shares, they may risk temporarily losing, or being limited in, 
the ability to remit foreign currency abroad and certain Brazilian tax advantages. 

The Brazilian custodian for the common shares and preferred shares underlying Oi’s ADSs must obtain an electronic registration 
number with the Brazilian Central Bank to allow the depositary to remit U.S. dollars abroad. ADS holders benefit from the electronic 
certificate of foreign capital registration from the Brazilian Central Bank obtained by the custodian for the depositary, which permits it 
to convert dividends and other distributions with respect to the common shares or preferred shares into U.S. dollars and remit the 
proceeds of such conversion abroad. If holders of Oi’s ADSs decide to exchange them for the underlying common shares or preferred 
shares, they will only be entitled to rely on the custodian’s certificate of registration with the Brazilian Central Bank for five business 
days after the date of the exchange. Thereafter, they will be unable to remit U.S. dollars abroad unless they obtain a new electronic 
certificate of foreign capital registration in connection with the common shares or preferred shares, which may result in expenses and 
may cause delays in receiving distributions. See “Item 10. Additional Information—Exchange Controls.” 

Also, if holders of Oi’s ADSs that exchange Oi’s ADSs for Oi’s common shares or preferred shares do not qualify under the 
foreign investment regulations, they will generally be subject to less favorable tax treatment of dividends and distribution on, and the 
proceeds from any sale of, Oi’s common shares or preferred shares. See “Item 10. Additional information—Exchange Controls” and 
“Item 10. Additional Information—Taxation—Brazilian Tax Considerations.”

Holders of Oi’s ADSs may face difficulties in protecting their interests because, as a Brazilian company, Oi is subject to different 
corporate rules and regulations, and Oi’s shareholders may have fewer and less well-defined rights. 

Holders of Oi’s ADSs are not direct shareholders of Oi and are unable to enforce the rights of shareholders under Oi’s by-laws and 

the Brazilian Corporate Law. 

Oi’s corporate affairs are governed by Oi’s by-laws and the Brazilian Corporate Law, which differ from the legal principles that 

would apply if Oi were incorporated in a jurisdiction in the United States, such as the State of Delaware or New York, or elsewhere 
outside Brazil. Even if a holder of Oi’s ADSs surrenders its ADSs and becomes a direct shareholder, its rights as a holder of Oi’s 
common shares or preferred shares under the Brazilian Corporate Law to protect its interests relative to actions by Oi’s board of 
directors may be fewer and less well-defined than under the laws of those other jurisdictions. 

Although insider trading and price manipulation are crimes under Brazilian law, the Brazilian securities markets are not as highly 
regulated and supervised as the U.S. securities markets or the markets in some other jurisdictions. In addition, rules and policies against 
self-dealing or for preserving shareholder interests may be less well-defined and enforced in Brazil than in the United States and certain 
other countries, which may put holders of Oi’s common shares, preferred shares and ADSs at a potential disadvantage. Corporate 
disclosures also may be less complete or informative than those of a public company in the United States or in certain other countries. 

Oi is exempt from some of the corporate governance requirements of the New York Stock Exchange. 

Oi is a foreign private issuer, as defined by the SEC for purposes of the Exchange Act. As a result, for so long as Oi remains a 
foreign private issuer, Oi will be exempt from, and you will not be provided with the benefits of, some of the corporate governance 
requirements of The New York Stock Exchange, or the NYSE. Oi is permitted to follow practice in Brazil in lieu of the provisions of 
the NYSE’s corporate governance rules, except that: 

•

•

•

•

Oi is required to have an audit committee that satisfies the requirements of Rule 10A-3 under the Exchange Act; 

Oi is required to disclose any significant ways in which Oi’s corporate governance practices differ from those followed by 
domestic companies under NYSE listing standards; 

Oi’s chief executive officer is obligated to promptly notify the NYSE in writing after any of Oi’s executive officers becomes 
aware of any non-compliance with any applicable provisions of the NYSE corporate governance rules; and 

Oi must submit an executed written affirmation annually to the NYSE. In addition, Oi must submit an interim written 
affirmation as and when required by the interim written affirmation form specified by the NYSE. 

The standards applicable to Oi are considerably different than the standards applied to U.S. domestic issuers. Although Rule 

10A-3 under the Exchange Act generally requires that a listed company have an audit committee of its board of directors composed 
solely of independent directors, as a foreign private issuer, Oi is relying on a general exemption from this requirement that is available 
to it as a result of the features of Brazilian law applicable to Oi’s fiscal council. In addition, Oi is not required to, among other things: 

•

•

•

•

have a majority of independent members of Oi’s board of directors; 

have a compensation committee or a nominating or corporate governance committee of Oi’s board of directors; 

have regularly scheduled executive sessions with only non-management directors; or 

have at least one executive session of solely independent directors each year. 

Oi intends to rely on some or all of these exemptions. As a result, you will not be provided with the benefits of certain corporate 

governance requirements of the NYSE. 

We could be adversely affected by violations of anti-corruption laws and regulations. 

We are required to comply with Brazilian anti-corruption laws and regulations, including Law No. 12,846/2013, or the Brazilian 

Anti-Corruption Law, as well as anti-corruption laws and regulations in other jurisdictions, including the U.S. Foreign Corrupt Practices 
Act of 1977, or the FCPA.

The Brazilian Anti-Corruption Law, the FCPA and similar anti-corruption laws in other jurisdictions generally prohibit companies 

and their intermediaries from making improper payments to government officials or other persons for the purpose of obtaining or 
retaining business. Recent years have seen a substantial increase in anti-corruption law enforcement activity, with more frequent and 
aggressive investigations and enforcement proceedings by both the U.S. Department of Justice and the SEC, increased enforcement 
activity by non-U.S. regulators, and increases in criminal and civil proceedings brought against companies and individuals. Our policies 
mandate compliance with these anti-corruption laws. We operate, through our businesses, in countries that are recognized as having 
governmental and commercial corruption. We cannot assure you that our internal control policies and procedures will protect us from 
reckless or criminal acts committed by our employees, the employees of any of our businesses, or third party intermediaries. In the 
event that we believe or have reason to believe that our employees or agents have or may have violated applicable anti-corruption laws, 
including the FCPA, we may be required to investigate or have outside counsel investigate the relevant facts and circumstances, which 
can be expensive and require significant time and attention from senior management. Violations of these laws may result in criminal or 
civil sanctions, inability to do business with existing or future business partners (either as a result of express prohibitions or to avoid the 
appearance of impropriety), injunctions against future conduct, profit disgorgements, disqualifications from directly or indirectly 
engaging in certain types of businesses, the loss of business permits or other restrictions which could disrupt our business and have a 
material adverse effect on our business, financial condition, results of operations or liquidity. 

Holders of Oi’s ADSs may face difficulties in serving process on or enforcing judgments against us and other persons. 

Oi is organized under the laws of Brazil, and all of the members of Oi’s board of directors, Oi’s executive officers and Oi’s 
independent registered public accountants reside or are based in Brazil. The vast majority of Oi’s assets and those of these other persons 
are located in Brazil. As a result, it may not be possible for holders of Oi’s ADSs to effect service of process upon Oi or these other 
persons within the United States or other jurisdictions outside Brazil or to enforce against Oi or these other persons judgments obtained 
in the United States or other jurisdictions outside Brazil. In addition, because substantially all of Oi’s assets and all of Oi’s directors and 
officers reside outside the United States, any judgment obtained in the United States against Oi or any of our directors or officers may 
not be collectible within the United States. Because judgments of U.S. courts for civil liabilities based upon the U.S. federal securities 
laws may only be enforced in Brazil if certain conditions are met, holders may face greater difficulties in protecting their interests in the 
case of actions by us or Oi’s board of directors or executive officers than would shareholders of a U.S. corporation. 

Brazilian tax laws may have an adverse impact on the taxes applicable to the disposition of Oi’s common shares, preferred shares and 
ADSs. 

According to Law No. 10,833, enacted on December 29, 2003, if a nonresident of Brazil disposes of assets located in Brazil, the 
transaction will be subject to taxation in Brazil, even if such disposition occurs outside Brazil or if such disposition is made to another 
nonresident. A disposition of Oi’s ADSs between nonresidents, however, involves the disposal of a non-Brazilian asset and in principle 
is currently not subject to taxation in Brazil. Nevertheless, in the event that the concept of “disposition of assets” is interpreted to 
include the disposition between nonresidents of assets located outside Brazil, this tax law could result in the imposition of withholding 
taxes in the event of a disposition of Oi’s ADSs made by nonresidents of Brazil. Due to the fact that, as of the date of this annual report, 
Law No. 10,833/2003 has no judicial guidance as to its application, Oi is unable to predict whether an interpretation applying such tax 
laws to dispositions of Oi’s ADSs between nonresidents could ultimately prevail in Brazilian courts. See “Item 10. Additional 
Information—Taxation—Brazilian Tax Considerations.”

If Oi is characterized as a passive foreign investment company in any taxable year, certain adverse U.S. federal income tax 
consequences could apply to a U.S. investor who holds Oi’s common shares, preferred shares or ADSs during such year. 

Oi will be classified as a passive foreign investment company, or PFIC, in any taxable year if either: (1) 50% or more of the fair 

market value of our gross assets (determined on the basis of a quarterly average) for the taxable year produce passive income or are held 
for the production of passive income, or (2) 75% or more of our gross income for the taxable year is passive income. As a publicly 
traded foreign corporation Oi intends for this purpose to treat the aggregate fair market value of our gross assets as being equal to the 
aggregate value of our outstanding stock plus the total amount of our liabilities (“Market Capitalization”) and to treat the excess of the 
fair market value of our assets over their book value as a nonpassive asset to the extent attributable to our nonpassive income. Based on 
the market price of Oi’s common shares and preferred shares and the composition of Oi’s assets, Oi believes that it was not a PFIC for 
U.S. federal income tax purposes either of Oi’s taxable years ended December 31, 2016 or December 31, 2017. Nevertheless, because 
PFIC status is determined annually based on Oi’s income, assets and activities for the entire taxable year, it is not possible to determine 
whether Oi will be characterized as a PFIC for the taxable year ending December 31, 2018, or for any subsequent year, until after the 
close of the year. Furthermore, because Oi determines the value of its gross assets based on the Market Capitalization test, a decline in 
the value of its ordinary shares and preferred shares may result in Oi becoming a PFIC. Accordingly, there can be no assurance that Oi 
will not be considered a PFIC for any taxable year. 

If Oi is characterized as a PFIC, certain adverse U.S. federal income tax consequences could apply to a U.S. investor who holds 

Oi’s common shares, preferred shares or ADSs during such year with respect to any “excess distribution” received from Oi and any 
gain from a sale or other disposition of Oi’s common shares, preferred shares or ADSs, and U.S. investors also may be subject to 
additional reporting obligations with respect to Oi’s common shares, preferred shares or ADSs. Oi does not intend to provide the 
information necessary for the U.S. investor to make a qualified electing fund election with respect to Oi’s common shares, preferred 
shares or ADSs. See “Item 10. Additional Information—Taxation – U.S. Federal Income Tax Considerations – Passive Foreign 
Investment Company Rules.” 

If a United States person is treated as owning at least 10% of Oi’s shares, such holder may be subject to adverse U.S. federal income 
tax consequences. 

If a United States person is treated as owning (directly, indirectly or constructively) at least 10% of the value or voting power of 
Oi’s shares, such person may be treated as a “United States shareholder” with respect to each “controlled foreign corporation” in our 
group (if any). If United States shareholders own (or are treated as owning) more than 50% of the value or voting power of Oi’s shares, 
Oi would (and our non-U.S. subsidiaries could) be treated as controlled foreign corporations. In addition, if our group includes one or 
more U.S. subsidiaries, certain of our non-U.S. subsidiaries could be treated as controlled foreign corporations (regardless of whether 
we are treated as a controlled foreign corporation). A United States shareholder of a controlled foreign corporation may be required to 
report annually and include in its U.S. taxable income its pro rata share of “Subpart F income,” “global intangible low-taxed income” 
and investments in U.S. property by controlled foreign corporations, regardless of whether we make any distributions. An individual 
that is a United States shareholder with respect to a controlled foreign corporation generally would not be allowed certain tax 
deductions or foreign tax credits that would be allowed to a United States shareholder that is a U.S. corporation. Failure to comply with 
these reporting obligations may subject you to significant monetary penalties and may prevent the statute of limitations with respect to 
your U.S. federal income tax return for the year for which reporting was due from starting. We cannot provide any assurances that we 
will assist investors in determining whether any of our non-U.S. subsidiaries are treated as a controlled foreign corporation or whether 
such investor is treated as a United States shareholder with respect to any of such controlled foreign corporations or furnish to any 
United States shareholders information that may be necessary to comply with the aforementioned reporting and tax paying 
obligations. Certain of our shareholders may be United States shareholders. The determination of controlled foreign corporation status 
is complex and includes attribution rules, the application of which is not entirely certain. A United States investor should consult its 
advisors regarding the potential application of these rules to an investment in Oi’s common shares, preferred shares or ADSs.

The relative volatility and illiquidity of the Brazilian securities markets may adversely affect holders of Oi’s common shares and 
Common ADSs. 

The Brazilian securities markets are substantially smaller, less liquid and more volatile than major securities markets in the United 
States. The B3 S.A. – Brasil, Bolsa, Balcão (formerly BM&FBOVESPA), or B3, which is the principal Brazilian stock exchange, had a 
market capitalization of R$3.2 trillion (US$955.6 billion) as of December 31, 2017 and an average daily trading volume of 
R$8.7 billion (US$2.6 billion) for 2017. In comparison, aggregate market capitalization of the companies (including U.S. and non-U.S. 
companies) listed on the NYSE was US$22.1 trillion as of December 31, 2017 and the NYSE recorded an average daily trading volume 
of US$58.2 billion for 2017. There is also significant concentration in the Brazilian securities markets. The ten largest companies in 
terms of market capitalization represented approximately 53% of the aggregate market capitalization of the B3 as of December 31, 
2017. The ten most widely traded stocks in terms of trading volume accounted for approximately 39% of all shares traded on the B3 in 
2017. These market characteristics may substantially limit the ability of holders of Oi’s Common ADSs to sell the common shares 
underlying Oi’s Common ADSs at a price and at a time when they wish to do so and, as a result, could negatively impact the market 
price of Oi’s Common ADSs themselves. 

Trading on over-the-counter markets may be volatile and sporadic, which could depress the market price of Oi’s Preferred ADS and 
make it difficult for holders to resell Oi’s Preferred ADSs. 

On June 21, 2016, the NYSE determined that Oi’s Preferred ADSs should be suspended immediately from trading and 
commenced procedures to remove Oi’s Preferred ADSs from listing and registration on the NYSE based on the “abnormally low” 
trading price of the Preferred ADSs. On June 23, 2016, the OTC Markets Group, Inc. began publishing quotations for Oi’s Preferred 
ADS in the “pink sheets” under the trading symbol OIBRQ. Trading in stock quoted on over the counter markets is often thin, volatile, 
and characterized by wide fluctuations in trading prices due to many factors that may have little to do with our operations or business 
prospects. This volatility could depress the market price of Oi’s Preferred ADSs for reasons unrelated to operating performance. 
Moreover, the over the counter markets are not a stock exchange, and trading of securities on the over the counter markets is often more 
sporadic than the trading of securities listed on other stock exchanges such as the NASDAQ Stock Market, New York Stock Exchange 
or American Stock Exchange. Accordingly, holders of Oi’s Preferred ADSs may have difficulty reselling such securities. 

The imposition of IOF taxes may indirectly influence the price and volatility of Oi’s common shares, preferred shares and ADSs. 

Brazilian law imposes the Tax on Foreign Exchange Transactions, or the IOF/Exchange Tax, on the conversion of reais into 

foreign currency and on the conversion of foreign currency into reais. Brazilian law also imposes the Tax on Transactions Involving 
Bonds and Securities, or the IOF/Securities Tax, due on transactions involving bonds and securities, including those carried out on a 
Brazilian stock exchange. 

In October 2009, the Brazilian government imposed the IOF/Exchange Tax at a rate of 2.0% in connection with inflows of funds 

related to investments carried out by non-Brazilian investors in the Brazilian financial and capital markets with the objective of slowing 
the pace of speculative inflows of foreign capital into the Brazilian market and the appreciation of the real against the U.S. dollar. The 
rate of the IOF/Exchange Tax generally applicable to foreign investments in the Brazilian financial and capital markets was later 
increased to 6.0%. In December 2011, the rate of the IOF/Exchange Tax applicable to several types of investments was reduced back to 
zero percent. As of the date of this annual report, all investments in the Brazilian financial and capital markets are subject to the 
IOF/Exchange Tax rate of zero percent. 

In November 2009, the Brazilian government also established that the rate of the IOF/Securities Tax would apply to the transfer of 

shares with the specific purpose of enabling the issuance of ADSs. In December 2013, the rate of the IOF/Securities Tax applicable to 
transactions involving the issuance of ADSs was reduced to zero percent. 

The imposition of these taxes may discourage foreign investment in shares of Brazilian companies, including Oi, due to higher 

transaction costs, and may negatively impact the price and volatility of Oi’s ADSs and common shares on the NYSE and the B3.

We are one of the principal integrated telecommunications service providers in Brazil with approximately 59.7 million revenue 

generating units, or RGUs, as of December 31, 2017. We operate throughout Brazil and offer a range of integrated telecommunications 
services that include fixed-line and mobile telecommunication services, network usage (interconnection), data transmission services 
(including broadband access services), Pay-TV (including as part of double-play, triple-play and quadruple-play packages), internet 
services and other telecommunications services for residential customers, small, medium and large companies and governmental 
agencies. We own 355,273 kilometers of installed fiber optic cable, distributed throughout Brazil. Our mobile network covers areas in 
which approximately 90.2% of the Brazilian population lives and works. According to ANATEL, as of December 31, 2017, we had a 
16.5% market share of the Brazilian mobile telecommunications market and a 33.1% market share of the Brazilian fixed-line market. 

Our traditional Residential Services business in Brazil includes (1) local and long-distance fixed-line voice services and public 

telephones, in accordance with the concessions granted to us by ANATEL, (2) broadband services, (3) Pay-TV services, and 
(4) network usage services (interconnection). We are the largest fixed-line telecommunications company in Brazil in terms of total 
number of lines in service as of December 31, 2017. We are the principal fixed-line telecommunications services provider in our service 
areas, comprising the entire territory of Brazil other than the State of São Paulo, based on our 12.9 million fixed lines in service as of 
December 31, 2017, with a market share of 52.5% of the total fixed lines in service in our service areas as of December 31, 2017. 

We offer a variety of high-speed broadband services in our fixed-line service areas, including services offered by our subsidiaries 
Oi Mobile and Brasil Telecom Comunicação Multimídia Ltda. Our broadband services primarily utilize Asymmetric Digital Subscriber 
Line, or ADSL, technology. As of December 31, 2017, we had 5.9 million ADSL subscribers, representing 46% of our fixed lines in 
service as of that date. 

We offer Pay-TV services under our Oi TV brand. We deliver Pay-TV services throughout our residential service areas using DTH 

satellite technology. 

Our Personal Mobility Services business offers mobile telecommunications services throughout Brazil, as well as network usage 

services (interconnection). Based on our 39.0 million mobile subscribers as of December 31, 2017, we believe that we are one of the 
principal mobile telecommunications service providers in Brazil. Based on information available from ANATEL, as of December 31, 
2017 our market share was 16.5% of the total number of mobile subscribers in Brazil. 

Our B2B Services business provides voice, data and Pay TV services to our SME and corporate (including government) customers 

throughout Brazil. We also provide wholesale interconnection, network usage and traffic transportation services to other 
telecommunications providers. 

We also hold significant interests in telecommunications companies in Angola, Cape Verde, and São Tomé and Principe in Africa 
and Timor Leste in Asia. Our interests in telecommunications companies in Africa are held through Africatel, in which we own an 86% 
interest. Our interests in telecommunications companies in Timor Leste are held through TPT, in which we own a 76.14% interest. On 
September 16, 2014, our board of directors authorized our management to take the necessary measures to market our shares in 
Africatel, representing 75% of the share capital of Africatel. In addition, on June 17, 2015, our board of directors authorized our 
management to take the necessary measures to market our shares in TPT, representing 76.14% of the share capital of TPT. As a result, 
as of December 31, 2015, 2016 and 2017, we recorded the assets and liabilities of Africatel and TPT as held-for sale, although we do 
not record Africatel or TPT as discontinued operations in our income statement due to the immateriality of the effects of Africatel and 
TPT on our results of operations. Due to the many risks involved in the ownership of these interests, particularly our interest in Unitel, 
we cannot predict when a sale of these assets may be completed. 

Our principal executive office is located at Rua Humberto de Campos No. 425, 6 1/2th floor–Leblon, 22430-190 Rio de Janeiro, 

RJ, Brazil, and our telephone number at this address is (55-21) 3131-2918.

Our Judicial Reorganization Proceedings 

Background of Judicial Reorganization Proceedings 

Our Recent History and Development 

On March 9, 2016, following the notification of our company on February 25, 2016 by LetterOne Technology (UK) LLP, or 

LetterOne, that it could not proceed with a potential transaction in which LetterOne would make a capital contribution of up to 
US$4.0 billion in our company, contingent on the completion of a potential business combination with TIM, we retained PJT Partners 
as our financial advisor to assist us in evaluating financial and strategic alternatives to optimize our liquidity and debt profile. 

On April 15, 2016, meetings of holders of our 5th Issue of Unsecured, Nonconvertible Public Debentures, or the 5th issue, and our 
9th Issue of Simple, Unsecured, Nonconvertible Debentures in up to Two Series, for Public Distribution, or the 9th series, were held as a 
result of our failure to comply with certain financial ratios set forth in the instruments governing the 5th issue and the 9th issue. These 
defaults were not waived by the holders of these instruments, payments under these instruments were accelerated and in April 2016, the 
outstanding amount due under the 5th issue of R$1.5 million and the outstanding amount due under the 9th issue of R$21.5 million were 
repaid. These accelerations and repayments did not result in the accelerated maturity of any of our other indebtedness. 

On April 25, 2016, we entered into a customary non-disclosure agreement with Moelis & Company, who acts as advisor for a 

diverse ad hoc group of holders of the bonds issued by Oi and its subsidiaries, or the Ad Hoc Group, as an initial step towards 
discussions of a potential restructuring of our indebtedness. 

Although we engaged in negotiations with the Ad Hoc Group seeking mutual agreement as to the basis for a consensual 

restructuring of the indebtedness of our company, after considering the challenges arising from our economic and financial situation in 
connection with the maturity schedule of our financial debts, the threats to our cash flows represented by imminent attachments or 
freezing of assets in judicial lawsuits, and the urgent need to adopt measures that protect our company, we concluded that filing of a 
request for judicial reorganization (recuperação judicial) in Brazil would be the most appropriate course of action (1) to preserve the 
continuity of our offering of quality services to our customers, within the rules and commitments undertaken with ANATEL, (2) to 
preserve the value of our company, (3) to maintain the continuity of our operations and corporate activities in an organized manner that 
protects the interests of our company, customers, shareholders and other stakeholders, and (4) to protect our cash and cash equivalents. 

Judicial Reorganization Proceedings 

On June 20, 2016, Oi, together with the other RJ debtors, filed a joint voluntary petition for judicial reorganization pursuant to the 

Brazilian Bankruptcy Law with the RJ Court, pursuant an urgent measure approved by our board of directors. 

The filing of the petition that commenced the RJ Proceedings was a step towards our financial restructuring. During the RJ 
Proceedings, we have, and expect to continue (1) to work to secure new customers while maintaining our service and product sales to 
all market segments, in all of our distribution and customer service channels, (2) to perform installation, maintenance and repair 
activities on a timely basis, (3) to use our workforce as usual, including to perform sales, operating and administrative activities, and 
(4) to focus on our investments in structuring projects aimed at promoting the improvement of service quality and continuing to bring 
technologic advances, high service standards, and innovation to our customers. 

On June 29, 2016, the RJ Court granted the processing of the RJ Proceedings of the RJ Debtors. The order of the RJ court granting 
this processing included, among other things, (1) a decision to grant an emergency measure regarding the suspension of all lawsuits and 
execution actions against the RJ Debtors for 180 business days, (2) the suspension of the effectiveness of clauses of contracts executed 
by the RJ Debtors that cause the termination of such contracts due to the request for judicial reorganization, (3) the requirement that the 
RJ Debtors add “in judicial reorganization” after their respective business names, and (4) the requirement that the RJ Debtors present 
monthly statements of accounts throughout the RJ Proceedings.

On July 22, 2016: 

•

•

the request for judicial reorganization was ratified by the shareholders of Oi at an extraordinary shareholders’ meeting. 

the RJ Court appointed PricewaterhouseCoopers Assessoria Empresarial Ltda. as the judicial administrator of the RJ Debtors 
responsible for verification of claims and opinions on financial matters, and appointed Escritório de Advocacia Arnoldo 
Wald e Advogados Associados to act as the judicial administrator of the RJ Debtors responsible for opinions on legal matters 
and verification of claims. We refer to the judicial administrators of the RJ Debtors in Brazil singly and collectively as the 
Judicial Administrator. 

On September 5, 2016, the RJ Debtors filed an initial judicial reorganization plan with the RJ Court, which we refer to as the 
Initial RJ Plan, proposing the terms and conditions for the restructuring of the debt of the RJ Debtors, and proposing actions that could 
be adopted to overcome the financial distress of the RJ Debtors and ensure their continuity as going concerns, including 
(1) restructuring and balancing their liabilities; (2) actions during the RJ Proceedings designed to obtain new funds; and (3) the potential 
sale of capital assets. Under the Initial RJ Plan, the creditors of the RJ Debtors were classified in four separate classes: (1) labor claims, 
(2) secured claims, (3) unsecured claims (excluding claims of micro-business owners and small businesses), and (4) claims of 
microbusiness owners and small businesses. 

Under Brazilian law, the RJ Debtors were required to submit to the RJ Court a list of their creditors for publication, which we refer 

to as the First List of Creditors. The First List of Creditors submitted by the RJ Debtors to the RJ Court was published in the Official 
Gazette of the State of Rio de Janeiro on September 20, 2016. The total amount payable to parties not controlled by the RJ Debtors 
included in the First List of Creditors was approximately R$65.1 billion. Following the date of publication of the First List of Creditors, 
persons claiming to be creditors of the RJ Debtors were required to file with the Judicial Administrator on or prior to October 11, 2016 
(1) a proof of claim, if the amounts claimed to be owed to them were not included in the First List of Creditors, or (2) a statement of 
discrepancy if the creditor disputed the amount or classification of the amount claimed to be owed to it that was included in the First 
List of Creditors. Under Brazilian law, following the expiration of the period to file proofs of claim and statements of discrepancies, the 
Judicial Administrator of the RJ Debtors were required to submit to the RJ Court a revised list of creditors for publication, which we 
refer to as the Second List of Creditors. Under Brazilian law, only creditors with claims against the RJ Debtors, as verified through their 
inclusion in the Second List of Creditors, were entitled to vote at the GCM. 

On October 4, 2016, the RJ Court rendered a decision recognizing that the holders of beneficial interests in bonds issued by Oi, Oi 

Coop and PTIF had the right under the Brazilian Bankruptcy Law to individualize claims represented by their beneficial interests in 
those bonds and to vote in the GCM, but ruling that the trustees under the instruments under which such bonds were issued would be 
granted the right to represent and vote on behalf of holders of beneficial interests in those bonds that did not individualize their claims 
and therefore would be otherwise unable to vote in the GCM, or the Trustee Voting Decision. The Trustee Voting Decision was 
appealed by the RJ Debtors, and on October 31, 2017, the Brazilian Court of Appeals denied the appeal filed by the RJ Debtors, 
confirming the Trustee Voting Decision and allowing the trustees under the instruments under which such bonds were issued to 
represent and vote in the GCM on behalf of holders of beneficial interests in those bonds that did not individualize their claims. 

On November 21, 2016, we engaged Laplace Finanças Empreendimentos e Participações Ltda. as our financial advisor with 

respect to the RJ proceeding and related matters, replacing PJT Partners.

On March 22, 2017, Oi’s board of directors approved an adjustment of the basic financial conditions presented in the Initial RJ 

Plan and authorized Oi’s executive officers and advisors to present to the RJ Court an amendment to the Initial RJ Plan as soon as 
possible. These adjustments were formulated on the basis of (1) more than 50 face-to-face meetings in Brazil and abroad with various 
creditors of the RJ Debtors, including national and international banks, development institutions and bondholders, as well as their 
respective advisors, and (2) other meetings with suppliers, ANATEL and small creditors. On March 28, 2017, the Company presented 
to the RJ Court information about the adjustment of the basic financial conditions presented in the Initial RJ Plan. 

On March 31, 2017, the RJ Court removed PricewaterhouseCoopers Assessoria Empresarial Ltda. from its role as Judicial 
Administrator, and on April 10, 2017 the RJ Court appointed Escritório de Advocacia Arnoldo Wald e Advogados Associados as the 
sole Judicial Administrator in the RJ Proceedings. 

On May 15, 2017, the RJ Court granted an extension of the stay period under the RJ Proceedings until the earliest of (1) the 180th 
business days following the date of the extension, or (2) the date on which the GCM was convened (whether on first call or second call). 

On May 29, 2017, following the review by the Judicial Administrator of all proofs of claim and statements of discrepancy, and the 

completion of necessary revisions, the Second List of Creditors was published in the Official Gazette of the State of Rio de Janeiro. 
Following the publication of the Second List of Creditors, persons claiming to be creditors of the RJ Debtors were permitted to file 
challenges to the Second List of Creditors with the RJ Court on or prior to the 10th business day following publication. In addition, 
creditors recognized in the Second List of Creditors were permitted to file objections to the Initial RJ Plan filed by the RJ Debtors with 
the RJ Court on or prior to the 30th business day following publication. 

On July 19, 2017, based on our progress in our discussions with various creditors, our board of directors authorized our executive 

officers to discuss with our creditors, potential investors and our shareholders potential changes to the Initial RJ Plan relating to our 
capital structure, potential alternative judicial reorganization plans, and a potential cash infusion in our company through a capital 
increase. 

On August 21, 2017, the RJ Court ruled that the RJ Debtors should be substantively consolidated in the RJ Proceeding, effectively 

requiring pooling the assets and liabilities of the RJ Debtors for purposes of distributions to creditors under a judicial reorganization 
plan and the creditors for purposes of voting on the any judicial reorganization plan, which we refer to as the Substantive Consolidation 
Decision. The Substantive Consolidation Decision was appealed by several creditors of the RJ Debtors, by Mr. Berkenbosch, in his 
capacity as Oi Coop’s bankruptcy trustee in the Netherlands, and by Mr. Groenewegen, in his capacity as PTIF’s bankruptcy trustee in 
the Netherlands, and on September 22, 2017, the Brazilian Court of Appeals rendered preliminary decisions staying the effects of the 
Substantive Consolidation Decision, ruling that (1) the Judicial Administrator was required to present segregated lists of creditors for 
each of the RJ Debtors and provide any relevant information to adequately assess each of the RJ Debtors independently, and (2) the 
GCM would be required to hold a vote on the issue of substantive consolidation separately from a vote on the any judicial 
reorganization plan. The Brazilian Court of Appeals ruled that the creditors’ vote would determine whether to substantively consolidate 
the RJ Debtors unless the Brazilian Court of Appeals ruled otherwise in the trial of the appeals. 

On August 23, 2017, following the expiration of the period for creditors to object to the Initial RJ Plan, the RJ Court scheduled the 

dates for the GCM. The GCM was scheduled to take place on first call on October 9, 2017. If the quorum requirements of this meeting 
were not met, the GCM was scheduled to take place on second call (with no quorum requirement) on October 23, 2017. 

On August 30, 2017, based on our progress in its discussions with certain holders of bonds issued by Oi, Oi Coop and PTIF, we 

entered into non-disclosure agreements with certain holders of these bonds, which we refer to as the unaffiliated bondholders, to 
facilitate discussions and negotiations concerning our capital structure, potential alternative judicial reorganization plans, and a potential 
cash infusion in our company through a capital increase. We, together with our financial and legal advisors, met with these bondholders 
and their financial and legal advisors, on multiple occasions in August, September and October 2017 to discuss the terms of potential 
revisions to the Initial RJ Plan and related transactions.

On September 27, 2017, the RJ Debtors requested that the RJ Court postpone the GCM by 15 days so that the GCM scheduled on 

first call would take place on October 23, 2017, and the GCM on second call would take place November 27, 2017. The RJ Court 
approved this request on the same day. 

On October 10, 2017, based on our progress in its discussions with certain holders of bonds issued by Oi, Oi Coop and PTIF, we 

entered into non-disclosure agreements with the certain holders of bonds that are members of the steering committee of the Ad Hoc 
Group, as well as certain holders of bonds that are members of the steering committee of the IBC to facilitate potential discussions and 
negotiations concerning potential revisions to the Initial RJ Plan and related transactions. We, together with our financial and legal 
advisors, met with these bondholders and their financial and legal advisors, as well as representatives of certain export credit agencies 
that are creditors of some of the RJ Debtors and their financial and legal advisors, on multiple occasions in October, November and 
December 2017 to discuss the terms of potential revisions to the Initial RJ Plan, subsequent judicial reorganization plans, and related 
transactions. 

Also on October 10, 2017, our board of directors approved a revised judicial reorganization plan, or the Second RJ Plan, which 

was filed with the RJ Court on October 11, 2017. 

On October 11, 2017, we and our financial and legal advisors met with the unaffiliated bondholders and their financial and legal 

advisors to discuss and negotiate a draft written restructuring term sheet representing the terms of a potential judicial reorganization 
plan contemplating, among other things, the terms of a potential capital increase, and a draft form of plan support agreement. 

On October 20, 2017, in response to the requests made by certain creditors of the RJ Debtors, the RJ Court postponed the GCM 
scheduled on first call by 14 days until November 6, 2017; the GCM on second call was not postponed and continued to be scheduled 
for November 27, 2017. 

On October 23, 2017, in response to a request from the Judicial Administrator, the RJ Court postponed the GCM scheduled on 

first call by four days until November 10, 2017; the GCM on second call was not postponed and continued to be scheduled for 
November 27, 2017. 

On November 3, 2017, our board of directors resolved to approve the final terms of a plan support agreement negotiated with the 

unaffiliated bondholders to be offered to all holders of bonds issued by Oi, Oi Coop and PTIF, and to authorize us to file an amendment 
to the Second RJ Plan with the RJ Court, contemplating the final terms of the plan support agreement. 

On November 6, 2017, ANATEL ordered us to, among other things, (1) formally submit to ANATEL the draft plan support 
agreement approved by Oi’s board of directors on November 3, 2017, and (2) refrain from signing the plan support agreement prior to 
its review by ANATEL. 

On November 9, 2017, in response to new requests made by certain creditors of the RJ Debtors, the RJ Court postponed the GCM 
so that the GCM scheduled on first call would take place on December 7, 2017 (continuing on December 8, 2017, if necessary), and the 
GCM on second call would take place February 1, 2018 (continuing on February 2, 2018, if necessary). 

On November 17, 2017, the RJ Court ordered that certain of Oi’s executive officers that had been appointed by Oi’s board of 

directors on November 3, 2017 were not permitted to participate in the negotiation of our judicial reorganization plan prior to further 
review of their appointments and powers by the RJ Court. 

On November 22, 2017, Oi’s board of directors approved a revised plan support agreement and a revised judicial reorganization 

plan, or the Third RJ Plan, which were filed with the RJ Court on November 27, 2017 following the resignation of Oi’s chief executive 
officer on November 24, 2017 and the election of Oi’s general counsel as Oi’s new chief executive officer on November 27, 2017. On 
November 27, 2017, ANTEL ordered us not to execute the revised plan support agreement.

On November 29, 2017, the RJ Court again postponed the GCM scheduled on first call until December 19, 2017 (continuing on 

December 20, 2017, if necessary); the GCM on second call was not postponed and continued to be scheduled for February 1, 2018 
(continuing on February 2, 2018, if necessary). In its decision, the RJ Court, (1) confirmed its earlier suspension of the power of certain 
of Oi’s executive officers that had been appointed by our board of directors on November 3, 2017 to participate in the negotiation of our 
judicial reorganization plan, and (2) directed Oi’s chief executive officer to present a revised judicial reorganization plan for 
consideration by the GCM no later than December 12, 2017. 

On December 12, 2017, as directed by the RJ Court and with the approval of Oi’s chief executive officer, the RJ Debtors filed a 

revised judicial reorganization plan, or the Fourth RJ Plan, with the RJ Court. 

ANATEL Proceedings 

Concurrently with our negotiations with our financial creditors, we engaged in negotiation and litigation with ANATEL, our 

largest creditor, with respect to the treatment of outstanding claims for fines, interest and penalties in the RJ Proceedings. On 
November 22, 2016, a hearing was held with the goal of consensually resolving ANATEL’s claims against the RJ Debtors’ as part of a 
mediation procedure initiated under RJ Proceedings. 

The Second List of Creditors recognized claims of ANATEL in the aggregate amount of approximately R$11.1 billion. We 
disagree with and are challenging some of the noncompliance events alleged by ANATEL, and are also challenging the fairness of the 
penalties, emphasizing the unreasonableness of the amount of the imposed fines in light of the alleged noncompliance events. 

The inclusion of the claims of ANATEL in the RJ Debtor’s judicial reorganization plan does not require the consent of ANATEL, 

but instead depends on the recognition of the applicability of the RJ Proceedings to these claims. 

On June 9, 2017, ANATEL filed an appeal seeking to reverse the decision of the RJ Court that recognized the applicability of the 
RJ Proceedings to ANATEL’s claims. On August 29, 2017, the 8th Civil Chamber of the Rio de Janeiro State Court of Justice granted 
ANATEL’s appeal to maintain the name of the RJ Debtors in the databases of the credit protection agencies, but held that the 
pre-petition claims of ANATEL were not tax claims and, therefore, were subject to the RJ Proceedings. 

On September 4, 2017, ANATEL appealed the decision of the RJ Court that permitted the GCM to be held without granting the 

request made by ANATEL to exclude all of its claims. Judgment on this appeal by the Rio de Janeiro State Court of Justice is pending. 

On November 22, 2017, ANATEL filed a special and an extraordinary appeals against the decision of the 8th Civil Chamber of the 

Rio de Janeiro State Court of Justice that held that the claims of ANATEL were subject to the RJ Proceedings. Judgments on these 
appeals by the Superior Court of Justice and the Supreme Court of Brazil are pending. 

Small Creditor Program 

Due to the extraordinarily large number of creditors of the RJ Debtors and the requirement of the Brazilian Bankruptcy Law that 

creditors must appear personally or through a representative at a GCM in order to vote on any proposed judicial reorganization plan, we 
sought judicial approval of a program under which creditors could engage in mediation of their claims with us under which we would 
settle claims of less than R$50,000 without extinguishing those claims, which we refer to as the Small Creditor Program. 

On December 19, 2016, the RJ Court authorized us to conduct the Small Creditor Program. Under terms and conditions set forth 
in the Small Creditor Program, creditors of the RJ Debtors could participate in the Small Creditor Program and the RJ Debtors would 
prepay to the participating creditors up to R$50,000, such that (1) 90% would be prepaid upon the acceptance by such creditor of a 
settlement, and (2) the remaining 10% would be prepaid after the approval of a judicial reorganization plan. Creditors of the RJ Debtors 
with claims of more than R$50,000.00 were entitled to participate in the Small Creditors Program and receive (1) R$45,000 upon the 
acceptance of such Oi Creditor of a settlement, (ii) R$5,000 after the approval of a judicial reorganization plan, and (3) the remainder of 
their claims under the terms and conditions applicable to creditors holding claims of the same class as set forth in a judicial 
reorganization plan. Holders of bonds of Oi, Oi Coop and PTIF that were residents of Portugal were permitted to participate in the 
Small Creditor Program.

On June 22, 2017, one of our creditors, China Development Bank Corporation, appealed the ruling of the RJ Court that authorized 

us to conduct the Small Creditor Program. On June 26, 2017, the 8th Civil Chamber of the Rio de Janeiro State Court of Justice 
suspended the ruling of the RJ Court that authorized us to conduct the Small Creditor Program. On August 29, 2017, the Rio de Janeiro 
State Court of Justice reversed such decision and upheld the validity of the Small Creditors Program. Other creditors also filed similar 
appeals. 

The Small Creditors Program commenced on August 29, 2017 and terminated on December 8, 2017, with more than 34,000 
creditors holding more than R$360,000,000 of claims participating in the Small Creditor Program. As of the date of this annual report, 
all participating creditors have received the payments with respect to their prepetition credits that were due in accordance with the terms 
of the Small Creditors Program. 

Approval of Judicial Reorganization Plan at GCM 

On December 19 and 20, 2017, the GCM to consider approval of the Fourth RJ Plan was held following the confirmation that the 
required quorum of creditors of each of classes I, II, III, and IV was in attendance. The GCM was attended by (1) 83.02% of the Class I 
creditors holding 92.28% of the Class I claims (labor creditors), (2) 100% of the Class II creditors holding 100% of the Class II claims 
(secured creditors), (3) 59.95% of the Class II creditors holding 98.57% of the Class III claims (unsecured creditors), and (4) 51.58% of 
the Class IV creditors holding 59.04% of the Class IV claims (unsecured microbusiness owners and small businesses). 

During the GCM, our management engaged in further negotiations to make certain revisions to the Fourth RJ Plan with various 
parties-in-interest, including Brazilian banks, ANATEL, lenders under the RJ Debtors’ facilities with export credit agencies, the Ad 
Hoc Group, the IBC and other significant holders of the bonds of Oi, Oi Coop and PTIF. As part of the RJ Plan, we negotiated the terms 
of the Commitment Agreement with members of the Ad Hoc Group, the IBC and certain other unaffiliated bondholders under which 
such bondholders agreed to backstop an eventual cash capital increase by our company, which will be commenced following the full 
implementation of the RJ Plan. The GCM concluded on December 20, 2017 following the approval of a judicial reorganization plan 
reflecting amendments to the Fourth RJ Plan as negotiated during the course of the GCM, which we refer to as the RJ Plan. 

As required by the ruling of the Brazilian Court of Appeals, creditors voted first whether to determine whether to substantively 

consolidate the RJ Debtors. Substantive consolidation of the Debtors was approved by holders of (1) 99.5% of the claims of Oi present 
and voting in the GCM; (2) 96.90% of the claims of Oi Mobile present and voting; (3) 99.88% of the claims of Telemar present and 
voting; (4) 97.98% of the claims of Oi Coop present and voting; (5) 99.89% of the claims of PTIF present and voting; (6) 100% of the 
claims of Copart 4 present and voting; and (7) 100% of the claims of Copart 5 present and voting. 

The RJ Plan was approved by a significant majority of creditors of each class present at the GCM: (1) 100% of the Class I 
creditors present or represented at the GCM holding 100% of the Class I claims present or represented at the GCM; (2) 100% of the 
Class II creditors present or represented at the GCM holding 100% of the Class II claims present or represented at the GCM; (3) 99.56% 
of the Class III creditors present or represented at the GCM holding 72.17% of the Class III claims present or represented at the GCM; 
and (4) 99.8% of the Class IV creditors present or represented at the GCM holding 99.74% of the Class IV claims present or 
represented at the GCM. 

Under the Trustee Voting Decision, the trustees under the instruments under which the bonds of Oi, Oi Coop and PTIF were 

issued were be granted the right to represent and vote on behalf of holders of beneficial interests in those bonds that did not 
individualize their claims. However, both of those trustees chose to abstain from voting on behalf of such bondholders. 

Confirmation of Judicial Reorganization Plan by RJ Court 

On January 8, 2018, the RJ Court entered the Brazilian Confirmation Order, ratifying and confirming the RJ Plan, according to its 

terms, but modifying certain provisions of the RJ Plan. The Brazilian Confirmation Order was published in the Official Gazette of the 
State of Rio de Janeiro on February 5, 2018, the Brazilian Confirmation Date. 

The Brazilian Confirmation Order, according to its terms, is binding on all parties as long as its effects are not stayed. By 
operation of the RJ Plan and the Brazilian Confirmation Order (provided that no stay or appeal of the Brazilian Confirmation Order 
results in a change of the Brazilian Confirmation Date), the unsecured claims against the RJ Debtors have been novated and discharged 
under Brazilian law and holders of such claims are entitled only to receive the recoveries set forth in the RJ Plan in exchange for their 
claims in accordance with the terms and conditions of the RJ Plan.

As of the deadline to file interlocutory appeals, 24 interlocutory appeals had been filed against and 19 motions for clarification had 

been filed with respect to the Brazilian Confirmation Order (the RJ Court considered three simple petitions challenging the Brazilian 
Confirmation Order as motions for clarification). In addition, four motions for clarification had been filed against the decisions entered 
by the RJ Court in respect of the motions for clarification filed against the Brazilian Confirmation Order. Although subject to these 
pending clarification motions and interlocutory appeals, the Brazilian Confirmation Order has not been stayed, fully or partially, and 
therefore remains in full force and effect, according to its terms.

The deadline to file appeals against the Brazilian Conformation Order has been interrupted with respect to persons that have 

timely filed motions for clarification with respect to the Brazilian Confirmation Order until the date on which the RJ Court enters its 
decision in respect of such motions for clarification. Following the decision on any such motion for clarification, parties in interest have 
to file an appeal within 15 business days from the date of such decision. 

Following the resolution of these appeals and motions for clarification, including eventual appeals to the Brazilian Superior and 

Supreme Courts, if any, the Brazilian Confirmation Order will become final and binding on all parties under Brazilian law. 

In the context of the RJ Proceedings, certain balances of consolidated assets and liabilities increased as a result of the inclusion of 

the RJ Debtors in RJ Proceedings and the resulting suspension of the payment of certain assumed liabilities. The main balances of 
consolidated assets and liabilities affected were cash, cash equivalents, cash investments, receivables from reciprocal services provided 
to telecom carriers, trade payables, and borrowings and financing. 

Implementation of the Judicial Reorganization Plan 

Under the RJ Plan, certain groups of creditors were entitled to make elections with respect to the form of the recovery that they 

were entitled to receive. The period to make these elections commenced on the Brazilian Confirmation Date and was scheduled to 
expire on February 26, 2018. On February 26, 2018, the RJ Court extended the election deadline applicable to beneficial holders of 
bonds issued by Oi, Oi Coop and PTIF until March 8, 2018. 

As of the end of the election period applicable to our loans and financings, other than the bonds issued by Oi, Oi Coop and PTIF, 
creditors had made elections with respect to the various forms of recovery available to them as described under “Item 5. Operating and 
Financial Review and Prospects—Liabilities Subject to Compromise.” 

As of the end of the election period applicable to the bonds issued by Oi, Oi Coop and PTIF, Qualified Bondholders with 
Bondholder Credits representing an aggregate of US$8,463 million of claims had elected to receive the Qualified Recovery and 
Non-Qualified Bondholders with Bondholder Credits representing an aggregate of US$187 million of claims had elected to receive the 
Non-Qualified Recovery. In the event that all such holders participate in the settlement procedures, we expect (1) to issue 
approximately US$1,655 million principal amount of New Notes, approximately 1,516 million new common shares and Warrants to 
subscribe to approximately 117 million new common shares, (2) that the aggregate principal amount of the Non-Qualified Credit 
Agreement will be approximately US$94 million, and (3) the holders of the remaining outstanding Bondholder Credits will be entitled 
to the Default Recovery with an aggregate principal amount of approximately US$1,094 million. For more information regarding the 
recoveries available to the holders of the bonds issued by Oi, Oi Coop and PTIF, see “Item 5. Operating and Financial Review and 
Prospects—Liabilities Subject to Compromise—Fixed Rate Bonds.” 

Recognition Proceedings in the United States 

On June 22, 2016, the U.S. Bankruptcy Court entered an order granting the provisional relief requested by the Chapter 15 Debtors 
in their cases that were filed on June 21, 2016 under Chapter 15 of the United States Bankruptcy Code. This provisional relief prevents 
(1) creditors from initiating actions against the Chapter 15 Debtors or their property located within the territorial jurisdiction of the 
United States, and (2) parties from terminating their existing U.S. contracts with the Chapter 15 Debtors. 

On July 21, 2016, the U.S. Bankruptcy Court held a hearing with respect to the Chapter 15 Debtors petition for recognition of the 
RJ Proceedings as a main foreign proceedings with regard to each of the Chapter 15 Debtors and did not receive any objections to such 
petition. 

On July 22, 2016, the U.S. Bankruptcy Court granted the U.S. Recognition Order, as a result of which a stay was automatically 
applied, preventing (1) the filing, in the United States, of any actions against the Chapter 15 Debtors or their properties located within 
the territorial jurisdiction of the United States, and (2) parties from terminating their existing U.S. contracts with the Chapter 
15 Debtors.

On July 7, 2017, following affirmation of the Dutch Conversion Decisions by the Dutch Supreme Court, as described under 

“—Restructuring of Dutch Finance Subsidiaries,” Mr. J.R. Berkenbosch, in his capacity as Oi Coop’s bankruptcy trustee in The 
Netherlands, filed with the U.S. Bankruptcy Court a motion seeking modification or termination of the U.S. Recognition Order in 
respect of Oi Coop and filed a competing petition for recognition of the Dutch Bankruptcy Proceeding, as described under 
“—Restructuring of Dutch Finance Subsidiaries,” in respect of Oi Coop as the foreign main proceeding for purposes of U.S. law. 

On December 4, 2017, the U.S. Bankruptcy Court issued a written opinion, denying Mr. Berkenbosch’s motion and petition in its 
entirety and entered an order to that effect on December 26, 2017. As such, the U.S. Recognition Order remains in place with respect to 
the RJ Proceedings in respect of each of the Chapter 15 Debtors, including Oi Coop. 

On January 8, 2018, Mr. Berkenbosch filed a notice of appeal with the U.S. Bankruptcy Court indicating his intention to appeal 
the December 4 decision and the December 26 order of the U.S. Bankruptcy Court. On January 9, 2018, the IBC also filed a notice of 
appeal indicating its intention to appeal the December 4 decision and the December 26 order of the U.S. Bankruptcy Court. Neither 
Mr. Berkenbosch nor the IBC has sought a stay of the December 4 decision and the December 26 order of the U.S. Bankruptcy Court. 

On April 17, 2018, the foreign representative for the Chapter 15 Debtors filed a motion with the U.S. Bankruptcy Court seeking an 
order of that court granting, among other things, full force and effect to the RJ Plan and the Brazilian Confirmation Order in the United 
States. The deadline for objections to the proposed order set by the U.S. Bankruptcy Court was May 11, 2018. As of that date, Pharol, 
Bratel B.V. and Bratel S.à r.l. filed an objection to that motion in which they argued that the motion should be denied without prejudice 
or deferred consideration until after certain appellate proceedings, arbitration and mediation have been concluded in Brazil. 
Additionally, The Bank of New York Mellon filed a limited objection requesting to revise certain portions of the proposed order, but 
did not object to the motion itself. The U.S. Bankruptcy Court has scheduled a hearing on the objections to the proposed order on 
May 29, 2018. If the U.S. Bankruptcy Court grants the requested order, the claims with respect to our bonds issued under indentures 
governed by New York law will be novated and discharged under New York law and the holders of these bonds will be entitled only to 
receive the recovery set forth in the RJ Plan in exchange for the claims represented by these bonds. 

Recognition Proceedings in the United Kingdom 

On June 23, 2016, the High Court of Justice of England and Wales granted the U.K. Recognition Orders. Each of the U.K. 

Recognition Orders: 

•

•

•

stayed the commencement or continuation of individual actions or individual proceedings concerning the assets, rights, 
obligations or liabilities of Oi, Telemar and Oi Mobile; 

stayed execution against the assets of Oi, Telemar and Oi Mobile; and 

suspended the rights of Oi, Telemar and Oi Mobile to transfer, encumber or otherwise dispose of their assets. 

On July 28, 2016, the U.K. Recognition Order granted in respect of Oi Mobile was partially modified to lift the suspension on its 

rights to transfer, encumber or otherwise dispose of its assets. 

On April 10, 2018, PTIF deposited a draft of the PTIF Composition Plan with the Dutch Court and Oi Coop deposited a draft of 

the Oi Coop Composition Plan with the Dutch Court. The PTIF Composition Plan and the Oi Coop Composition Plan each provide for 
the restructuring of the claims against PTIF and Oi Coop on substantially the same terms and conditions as the RJ Plan. 

A meeting of the creditors of PTIF has been scheduled on June 1, 2018 at which the creditors of PTIF will consider the PTIF 

Composition Plan. If the PTIF Composition Plan is approved at the meeting of the creditors of PTIF, we expect that the Dutch Court 
will schedule a hearing on prior to June 15, 2018 to rule on the homologation of the PTIF Composition Plan. If the PTIF Composition 
Plan is homologated, the PTIF Composition Plan will be given full force and effect in each member state of the European Union, 
including England and Wales. 

A meeting of the creditors of Oi Coop has been scheduled on June 1, 2018 at which the creditors of Oi Coop will consider the Oi 

Coop Composition Plan. If the Oi Coop Composition Plan is approved at the meeting of the creditors of Oi Coop, we expect that the 
Dutch Court will schedule a hearing on prior to June 15, 2018 to rule on the homologation of the Oi Coop Composition Plan. If the Oi 
Coop Composition Plan is homologated, the Oi Coop Composition Plan will be given full force and effect in each member state of the 
European Union, including England and Wales. 

For more information regarding the anticipated homologation of the PTIF Composition Plan and the Oi Coop Composition Plan, 

see “—Restructuring of Dutch Finance Subsidiaries.”

Recognition Orders in Portugal 

On November 14, 2016, Oi and Telemar requested the Third Lisbon Commercial Court, or the Portuguese Court, to recognize the 
RJ Proceedings in relation to Oi and Telemar under the Portuguese Insolvency and Corporate Recovery Code in Portugal. On March 2, 
2017, the Portuguese Court issued a decision acknowledging the decision of the RJ Court that granted the processing of the RJ 
Proceedings of Oi and Telemar. 

On July 11, 2017, Oi Mobile requested the Portuguese Court to recognize the RJ Proceedings in relation to Oi Mobile under the 

Portuguese Insolvency and Corporate Recovery Code in Portugal. On August 9, 2017, the Portuguese Court issued a decision 
acknowledging the decision of the RJ Court that granted the processing of the RJ Proceedings of Oi Mobile. 

On May 9, 2018, Oi, Telemar and Oi Mobile, along with Copart 4 and Copart 5, filed a request for recognition of the RJ Plan in 

Portugal. As of the date of this annual report, a decision has not yet been rendered. 

Restructuring of Dutch Finance Subsidiaries 

Although the RJ Proceedings have been recognized in the United States, England and Wales, and Portugal, the laws of The 
Netherlands do not provide for the recognition of the RJ Proceedings. Two of the RJ Debtors, Oi Coop and PTIF, are organized under 
the laws of The Netherlands. As a result, a group of opportunistic litigious holders of some of the notes issued by Oi Coop and PTIF led 
by Aurelius Capital Management LP, or Aurelius, have brought proceedings against these RJ Debtors in The Netherlands. 

On June 27, 2016, Syzygy Capital Management, Ltd, or Syzygy, an affiliate of Aurelius, filed a petition for the involuntary 
bankruptcy of Oi Coop before the Dutch District Court, requesting that the Dutch District Court (1) declare Oi Coop in a state of 
bankruptcy, (2) declare the bankruptcy of Oi Coop a main insolvency proceeding within the meaning of Article 3.1 of the European 
Insolvency Regulation (EC no. 1346/2000). On July 8, 2016, Loomis Sayles Strategic Income Fund also filed a petition for the 
involuntary bankruptcy of Oi Coop in the Dutch District Court making similar requests as those made in the Oi Coop proceeding. On 
July 11, 2016, a group of beneficial holders of Oi Coop bonds filed an involuntary bankruptcy petition against Oi Coop in the Dutch 
District Court. On July 15, 2016, another group of beneficial holders of Oi Coop bonds filed an involuntary bankruptcy petition against 
Oi Coop in the Dutch District Court. 

On August 9, 2016 Oi Coop filed with the Dutch District Court a petition for a Dutch suspension of payments (verzoekschrift tot 

aanvragen surseance van betaling) proceeding, an insolvency proceeding aimed at facilitating the reorganization, rather than the 
liquidation, of an insolvent debtor by imposing a temporary stay against creditor actions. On August 9, 2016, the Dutch District Court 
granted the request of Oi Coop for the commencement of suspension of payment proceedings. 

On August 22, 2016, Citicorp Trustee Company Limited, or Citicorp, in its capacity as the trustee in respect of the a series of 
bonds issued by PTIF, purportedly acting at the direction of the requisite majority of the holders of these bonds, filed a petition for the 
involuntary bankruptcy of PTIF in the Dutch District Court requesting that the Dutch District Court (1) order the bankruptcy of PTIF, 
and (2) declare the bankruptcy of PTIF a main insolvency proceeding within the meaning of Article 3.1 of the European Insolvency 
Regulation (EC no. 1346/2000) 

On September 30, 2016, PTIF filed with the Dutch District Court a petition for a Dutch suspension of payments proceeding. On 
October 3, 2016, the Dutch District Court granted the request of PTIF for the commencement of suspension of payment proceedings. 

The Oi Coop and PTIF suspension of payments proceedings were initiated in order to ensure compatibility in The Netherlands 
with the RJ Proceedings initiated by the RJ Debtors in Brazil. These suspension of payment proceedings provide Oi Coop and PTIF 
with a stay against creditor action in The Netherlands, including actions with respect to the petitions for the involuntary bankruptcy, to 
allow them to restructure their debts with the ultimate aim of satisfying their creditors. In connection with the granting of the requests 
for the commencement of suspension of payment proceedings, (1) each of Oi Coop and PTIF filed a draft of a composition with 
creditors plan (akkoord), or a composition plan, (2) the Dutch District Court appointed Mr. Berkenbosch as administrator of Oi Coop, 
and set May 18, 2017 as the date on which Oi Coop’s creditors would vote on its composition plan, and (3) the Dutch District Court 
appointed Mr. J.L.M. Groenewegen as administrator of PTIF, and set May 18, 2017 as the date on which PTIF’s creditors would vote 
on its composition plan. 

On December 1, 2016, both Mr. Berkenbosch for Oi Coop and Mr. Groenewegen for PTIF filed a petition with the Dutch District 
Court requesting that the Oi Coop suspension of payments proceedings and the PTIF suspension of payments proceedings, respectively, 
be withdrawn and advising the Dutch District Court to declare Oi Coop and PTIF bankrupt. Subsequently, on December 23, 2016, the 
IBC filed a petition with the Dutch District Court requesting that the Oi Coop suspension of payments proceeding be withdrawn and 
that Oi Coop be declared bankrupt. On January 4, 2017, Citicorp filed a petition with the Dutch District Court requesting that the PTIF 
suspension of payments proceeding be withdrawn and PTIF be declared bankrupt.

On February 2, 2017, following hearings to consider these requests on January 12, 2017, the Dutch District Court rendered 

decisions denying each of these requests. 

On February 10, 2017, the IBC and Citicorp appealed the rulings of the Dutch District Court denying their respective requests to 

the Court of Appeal of Amsterdam, The Netherlands, or the Dutch Court of Appeal. 

On April 19, 2017, the Dutch Court of Appeals granted the appeals of the IBC and Citicorp, overturning the Dutch District Court 

decisions and ordering that the suspension of payments proceedings in respect of Oi Coop and PTIF be converted into Dutch
bankruptcy proceedings. The Dutch Court of Appeals further appointed Mr. Berkenbosch as Oi Coop’s bankruptcy trustee in the
Netherlands, and Mr. Groenewegen as PTIF’s bankruptcy trustee in the Netherlands. 

On July 7, 2017, upon certain appeals of the decisions of the Dutch Court of Appeals, the Dutch Supreme Court issued a decision 

affirming the decisions of the Dutch Court of Appeals. 

On April 10, 2018, PTIF deposited a draft of the PTIF Composition Plan with the Dutch Court and Oi Coop deposited a draft of 

the Oi Coop Composition Plan with the Dutch Court. The PTIF Composition Plan and the Oi Coop Composition Plan each provide for 
the restructuring of the claims against PTIF and Oi Coop on substantially the same terms and conditions as the RJ Plan. 

On April 10, 2018, Oi commenced a solicitation of votes of the holders of the seven series of bonds issued by PTIF in favor of a 
proposal to (1) approve extraordinary resolutions (a) releasing of Oi’s guarantee of the relevant series of bonds, and (b) instructing the 
trustee of such series of bonds to vote in favor of the PTIF Composition Plan and to provide a direction to the PTIF Bankruptcy Trustee 
in respect of its vote on behalf of PTIF on the Oi Coop Composition Plan; and (2) approve the PTIF Composition Plan. 

Under the documents governing the bonds issued by PTIF, these actions may be taken at a meeting of holders of the applicable 
series of bonds at which at least two-thirds of the principal amount of the applicable bonds are represented in person or by proxy. In the 
event that quorum is not obtained at any such meeting, these actions may be taken at a meeting of holders of the applicable series of 
bonds at a second meeting called for the purpose at which at least one-third of the principal amount of the applicable bonds are 
represented in person or by proxy. In either case, the proposed extraordinary resolution may be passed by the vote of not less than 75% 
of the principal amount of the applicable bonds represented in the meeting. 

The voting deadline under this voting solicitation was April 27, 2018 for one of these series of bonds and April 30, 2018 for the 
other six series of bonds. At meetings of each of these series of bonds held on May 2, 2018, quorum was not achieved for any of these 
series of bonds. As a result, on May 3, 2018, Oi published notices to convene adjourned meetings of each of these series of bonds on 
May 17, 2018 and establishing a new voting deadline of May 14, 2018. Based on the votes received as of the second voting deadline, 
we believe that each of the extraordinary resolutions will be passed and that each of these series of bonds will vote to approve the PTIF 
Composition Plan. 

A meeting of the creditors of PTIF has been scheduled on June 1, 2018 at which the creditors of PTIF will consider the PTIF 

Composition Plan and the votes solicited by Oi will be presented to the PTIF Bankruptcy Trustee. Based on the results of the voting 
solicitation, we expect that the creditors of PTIF will approve the PTIF Composition Plan, however we cannot assure you that 
procedural matters will not be raised at this meeting of creditors that will result in the failure of the creditors to approve the PTIF 
Composition Plan. 

If the PTIF Composition Plan is approved at the meeting of the creditors of PTIF, we expect that the Dutch Court will schedule a 
hearing on prior to June 15, 2018 to rule on the homologation of the PTIF Composition Plan. Although we expect that the Dutch Court 
will homologate the PTIF Composition Plan at that hearing, we cannot assure you that procedural matters will not be raised at this 
hearing that will result in the failure of the Dutch Court to homologate the PTIF Composition Plan. If the PTIF Composition Plan is 
homologated, the PTIF Composition Plan will be given full force and effect in each member state of the European Union. 

On April 10, 2018, Oi commenced a solicitation of votes of the holders of the two series of bonds issued by Oi Coop in favor of 

the Oi Composition Plan. The voting deadline under this voting solicitation was May 15, 2018. As of the voting deadline, the tabulation 
is in the process of being finalized.

A meeting of the creditors of Oi Coop has been scheduled on June 1, 2018 at which the creditors of Oi Coop will consider the Oi 

Coop Composition Plan and the votes solicited by Oi will be presented to the Oi Coop Bankruptcy Trustee and the PTIF Bankruptcy 
Trustee is expected to vote the claim represented by an intercompany loan made by PTIF to Oi Coop. Based on the preliminary results 
of the voting solicitation, if the extraordinary resolutions of the PTIF bonds are passed by all series of PTIF bonds instructing the PTIF 
Bankruptcy Trustee to vote the claim represented by an intercompany loan made by PTIF to Oi Coop in favor of the Oi Coop 
Composition Plan, we expect that the creditors of Oi Coop will approve the Oi Coop Composition Plan, however we cannot assure you 
that procedural matters will not be raised at this meeting of creditors that will result in the failure of the creditors to approve the Oi 
Coop Composition Plan. If the extraordinary resolutions of the PTIF bonds are not passed by all series of PTIF bonds, we cannot assure 
you as to how the PTIF Bankruptcy Trustee will vote the claim represented by an intercompany loan made by PTIF to Oi Coop, and if 
the PTIF Bankruptcy Trustee vote this claim against approval of the Oi Coop Composition Plan, we expect the Oi Coop Composition 
Plan will not be approved. 

If the Oi Coop Composition Plan is approved at the meeting of the creditors of Oi Coop, we expect that the Dutch Court will 
schedule a hearing on prior to June 15, 2018 to rule on the homologation of the Oi Coop Composition Plan. Although we expect that the 
Dutch Court will homologate the Oi Coop Composition Plan at that hearing, we cannot assure you that procedural matters will not be 
raised at this hearing that will result in the failure of the Dutch Court to homologate the Oi Coop Composition Plan. If the Oi Coop 
Composition Plan is homologated, the Oi Coop Composition Plan will be given full force and effect in each member state of the 
European Union. 

Changes to the Membership of Oi’s Board of Directors and Board of Executive Officers 

Since January 1, 2016, there have been numerous changes to the composition of Oi’s board of directors and board of executive 

officers. Prior to the filing of our request for judicial organization on June 20, 2016: 

•

•

•

On June 1, 2016, Fernando Marques dos Santos resigned as an alternate member of Oi’s board of directors. 

On June 10, 2016, (1) Bayard De Paoli Gontijo resigned as Oi’s chief executive officer, and Oi’s board of directors elected 
Marco Norci Schroeder as Oi’s chief executive officer, and (2) Robin Bienenstock resigned as a member of Oi’s board of 
directors and her alternate, Marcos Grodetzky, assumed her position as a member of Oi’s board of directors. 

On June 18, 2016, Luiz Antonio do Souto Gonçalves resigned as a member of Oi’s board of directors and his alternate, 
Joaquim Dias de Castro, assumed his position as a member of Oi’s board of directors; Joaquim Dias de Castro resigned as a 
member of Oi’s board of directors on June 22, 2016. 

Shortly following our request for judicial organization, on July 4, 2016, Marten Pieters resigned as a member of Oi’s board of 

directors and his alternate, Pedro Zanurtu Gubert Morais Leitao, assumed his position as a member of Oi’s board of directors. 

On July 7, 2016, one of Oi’s shareholders, Societé Mondiale Fundo de Investimento em Ações, or Société Mondiale, requested 

that Oi’s board of directors convene an extraordinary general shareholders meeting within the following eight days meeting to 
deliberate, among other things, (1) the dismissal of five of the members of Oi’s board of directors that were affiliated with another of 
Oi’s then-shareholder, Bratel B.V., and their respective alternate members, (2) the dismissal of one independent member of Oi’s board 
of directors, and (3) the election of new members and alternate members of Oi’s board of directors to replace the dismissed members 
and to fill existing vacancies on Oi’s board of directors. On July 8, 2016, Pedro Guimarães e Melo de Oliveira Guterres resigned as an 
alternate member of Oi’s board of directors. On July 14, 2016, Société Mondiale informed us that it extended the deadline for this 
extraordinary general shareholders meeting until July 22, 2016. 

On July 14, 2016, the RJ Court granted a request made by ANATEL that the RJ Court determine that prior approval from 

ANATEL is required for, among other things, the possible transfer of Oi’s corporate control, including the replacement of Oi’s board of 
directors. On July 22, 2016, Oi’s board of directors determined that, in light of the ruling of the RJ Court, it should not resolve upon 
Société Mondiale’s request to call an extraordinary general shareholders’ meeting prior to receiving a ruling of the RJ Court on the 
timeliness and propriety of the request to call such meeting.

On July 29, 2016, Société Mondiale requested that Oi’s board of directors convene an extraordinary general shareholders meeting 

within the following eight days meeting to deliberate, among other things, bringing lawsuits on behalf of the company against various 
parties, including certain members of Oi’s board of directors, in relation to our acquisition of PT Portugal SGPS S.A., or PT Portugal, in 
May 2014. On August 3, 2016, Oi’s board of directors determined that because any action taken at the meeting to bring actions against 
Oi’s management would imply a potential change of Oi’s board of directors as a result of Brazilian law requirements that members of 
Oi’s board of directors or board of executive officers be replaced upon the commencement of such action, the requested deliberations 
would produce the same effects as those contained in Société Mondiale’s previous request to convene an extraordinary general 
shareholders meeting, and Oi’s board of directors similarly should not resolve upon Société Mondiale’s request to call an extraordinary 
general shareholders’ meeting prior to receiving a ruling of the RJ Court on the timeliness and propriety of the request to call such 
meeting. 

On August 10, 2016, Société Mondiale published a call notice with respect to the extraordinary general shareholders meeting that 

it had requested, setting the date for such meeting as September 8, 2016. On August 12, 2016, Oi’s board of directors elected Marcos 
Duarte Santos and Ricardo Reisen de Pinho as members of Oi’s board of directors to fill vacancies on Oi’s board of directors. 

On September 2, 2016, the RJ Court suspended the extraordinary general shareholders meeting called by Société Mondiale for 
September 8, 2016 and determined that Bratel B.V. and Société Mondiale should carry out a mediation proceeding to be concluded 
within the following 20 days. 

On September 9, 2016, Marcos Grodetzky resigned as a member of Oi’s board of directors. On September 12, 2016, Flavio 
Nicolay Guimarães resigned as Oi’s chief financial officer and investor relations officer, and Oi’s board of directors elected Ricardo 
Malavazi Martins as Oi’s chief financial officer. In connection with this election, Ricardo Malavazi Martins resigned as a member of 
Oi’s board of directors. 

On September 13, 2016, Bratel B.V. and Société Mondiale announced that they had reached an agreement resolving a dispute 
between these shareholders regarding an extraordinary general shareholders’ meeting that Société Mondiale had called for September 8, 
2016. In accordance with their agreement, Société Mondiale requested that the chairman of Oi’s board of directors cancel the 
extraordinary general shareholders’ meetings. 

On September 14, 2016, Oi’s board of directors, in a meeting authorized by the RJ Court, elected Hélio Calixto da Costa and 

Demian Fiocca as members of Oi’s board of directors, and elected Nelson Sequeiros Rodriguez Tanure as alternate member of Oi’s 
board of directors to Hélio Calixto da Costa, Blener Braga Cardoso Mayhew as alternate member of Oi’s board of directors to Demian 
Fiocca, Nelson de Queiroz Sequeiros Tanure as alternate member of Oi’s board of directors to Marcos Duarte Santos, Pedro Grossi 
Junior as alternate member of Oi’s board of directors to Ricardo Reisen de Pinho, Luís Manuel da Costa de Sousa de Macedo as 
alternate member of Oi’s board of directors to João Manuel Pisco de Castro, and José Manuel Melo da Silva as alternate member of 
Oi’s board of directors to Pedro Zañartu Gubert Morais Leitão. 

On November 8, 2016, ANATEL issued an order in which it, among other things, (1) suspended the exercise of voting and veto 
rights by the members of Oi’s board of directors appointed by Société Mondiale, (2) prohibited the participation of members of Oi’s 
board of directors appointed by Societé Mondiale in Oi’s board of directors, and (3) ordered Oi to notify the Superintendence of 
Competition of ANATEL of the dates of meetings of Oi’s board of directors so that it could send a representative to attend such 
meetings; 

On January 6, 2017, ANATEL completed its prior approval process as ordered by the RJ Court on July 14, 2016, with respect to 

the members and alternate members of Oi’s board of directors elected on September 14, 2016 and determined (1) to grant prior approval 
for the effective entry to Oi’s board of directors for Hélio Calixto da Costa and Demian Fiocca as members of Oi’s board of directors 
and Nelson Sequeiros Rodriguez Tanure, Blener Braga Cardoso Mayhew, Luís Manuel da Costa de Sousa de Macedo, and José Manuel 
Melo da Silva as alternate members of Oi’s board of directors, (2) to deny prior approval for the effective entry to Oi’s board of 
directors for Nelson de Queiroz Sequeiros Tanure and Pedro Grossi Junior, and (3) to require that any modifications to Oi’s board of 
directors, including any modifications that concern alternate members of Oi’s board of directors, be submitted to ANATEL for the prior 
approval for as long as the RJ Proceedings is underway.

On March 7, 2017, Rafael Luis Mora Funes resigned as a member of Oi’s board of directors and his alternate, João do Passo 
Vicente Ribeiro, assumed his position as a member of Oi’s board of directors. 

On March 28, 2017, Nuno Rocha dos Santos de Almeida e Vasconcellos resigned as an alternate member of Oi’s board of 
directors. 

On May 24, 2017, Oi’s board of directors appointed Carlos Augusto Machado Pereira de Almeida Brandão as a member of 
Oi’s board of executive officers without specific designation. 

On June 21, 2017, Oi’s board of directors elected Marcio Guedes Pereira Junior as alternate member of Oi’s board of 
directors to Jose Mauro Mettrau Carneiro da Cunha, and William Connel Steers as alternate member of Oi’s board of 
directors to André Cardoso de Mendes Navarro. Although the effectiveness of these elections had been conditioned on the 
prior approval of ANATEL, ANATEL never decided on this matter, which was superseded by ANATEL’s approval on 
January 15, 2018 of Oi’s transitional board of directors appointed pursuant to the RJ Plan. For more information about Oi’s 
transitional board of directors, see “Item 6. Directors, Senior Managers and Employees—Board of Directors.” 

On September 19, 2017, Oi’s board of directors elected Francisco Marques da Cruz Vieira da Cruz as alternate member of 
Oi’s board of directors to João do Passo Vicente Ribeiro. Although the effectiveness of these elections had been conditioned 
on the prior approval of ANATEL, ANATEL never decided on this matter, which was superseded by ANATEL’s approval 
on January 15, 2018 of Oi’s transitional board of directors appointed pursuant to the RJ Plan. For more information about 
Oi’s transitional board of directors, see “Item 6. Directors, Senior Managers and Employees—Board of Directors.” 

On October 2, 2017, Ricardo Malavazi Martins resigned as Oi’s chief financial officer and investor relations officer, and Oi’s 
board of directors elected Carlos Augusto Machado Pereira de Almeida Brandão to serve as interim chief financial officer and investor 
relations officer. 

On November 3, 2017, Oi’s board of directors appointed two of its members, Hélio Calixto da Costa and João do Passo Vicente 

Ribeiro, as members of Oi’s board of executive officers without specific designation. On November 17, 2017, the RJ Court ordered that 
Hélio Calixto da Costa and João do Passo Vicente Ribeiro refrain from interfering in matters related to RJ Proceedings, as well as the 
negotiation and preparation of the judicial reorganization plan for the RJ Debtors, without prejudice to the regular exercise of their other 
operational duties in the direction of our company. 

On November 24, 2017, Marco Norci Schroeder resigned as Oi’s chief executive officer, and Oi’s board of directors elected 
Eurico De Jesus Teles Neto to serve as interim chief executive officer. On November 27, 2017, Oi’s board of directors elected Eurico 
De Jesus Teles Neto to serve as chief executive officer in addition to his position as chief legal officer. 

Pursuant to the RJ Plan, as from the date of the approval of the RJ Plan on December 20, 2017 until the election of Oi’s new board 

of directors in accordance with the RJ Plan, which is required to occur within 45 business days following the conclusion of the 
Qualified Recovery as part of the recovery of certain holders of bonds issued by Oi, Oi Coop and PTIF under the RJ Plan as further 
described under “Item 5. Operating and Financial Review and Prospects—Liabilities Subject to Compromise—Loans and 
Financing—Fixed Rate Notes—Qualified Recovery,” Oi has and will have a transitional board of directors composed of nine members 
set forth in the RJ Plan, each of whom will serve without an alternate member. As a result, on December 20, 2017, (1) João do Passo 
Vicente Ribeiro, André Cardoso de Menezes Navarro, Thomas Cornelius Azevedo Reichenheim, João Manuel Pisco de Castro and 
Demian Fiocca and each alternate member of Oi’s board of directors were removed from Oi’s board of directors, and (2) Marcos 
Rocha, Eleazar de Carvalho Filho, and Marcos Grodetzky were installed as members of Oi’s board of directors. The effectiveness of the 
installation of Marcos Rocha, Eleazar de Carvalho Filho, and Marcos Grodetzky as members of Oi’s board of directors was conditioned 
on the prior approval of ANATEL, which was granted on January 15, 2018. 

On December 28, 2017, one of Oi’s shareholders, Bratel S.à r.l, requested that Oi’s board of directors convene an extraordinary 

general shareholders’ meeting within eight days to deliberate on, among other things, bringing a lawsuit on behalf of Oi against 
members of Oi’s board of directors and board of executive officers in relation to the approval of the RJ Plan by the GCM. We submitted 
this request to the RJ Court for its decision on the legality and convenience of convening and holding the requested extraordinary 
general shareholders’’ meeting.

On January 8, 2018, Bratel S.à r.l published its proposal for deliberation at its requested extraordinary general shareholders’ 
meeting and scheduled such meeting for February 7, 2018. In its January 8, 2018 decision ratifying and confirming the RJ Plan, the RJ 
Court had stated that the amendments to Oi’s bylaws that were approved in the RJ Plan precluded the extraordinary shareholders 
meeting. On February 5, 2018, the RJ Court rejected Bratel S.à r.l’s request to partially reconsider this portion of its decision. 

On February 7, 2018, Bratel S.à r.l purported to convene an extraordinary general shareholders’ meeting and elect members of 

Oi’s board of directors. On that date, the RJ Court declared invalid and ineffective any out-of-court deliberation that undermined 
matters approved by the RJ Plan. On February 8, 2018, the RJ Court granted interlocutory relief to Oi’s denying the effectiveness of all 
resolutions taken at the purported extraordinary general shareholders’ meeting. 

On March 7, 2018, the RJ Court suspended the voting rights of the certain shareholders of Oi that participated in the purported 
extraordinary general shareholders’ meeting held on February 7, 2018, including Bratel S.à r.l and Société Mondiale, and ordered the 
removal of the members of Oi’s board of directors that had been elected/indicated by such shareholders them the completion of the 
Capitalization of Credits Capital Increase as part of the RJ Plan. As a result, Luis Maria Viana Palha da Silva, Pedro Zañartu Gubert 
Morais Leitão and Hélio Calixto da Costa were temporarily removed as members of Oi’s board of directors effective on March 7, 2018. 
Hélio Calixto da Costa also resigned as a member of Oi’s board of executive officers. The judicial decision also ordered the subpoena 
of the current executive officers of Oi and the shareholders whose voting rights were suspended, to express their interest in establishing 
a mediation proceeding. Oi (on behalf of itself and its executive officer), Bratel S.à r.l and Société Mondiale have manifested their 
interest in a mediation. Oi filed a petition stating that, since Société Mondiale has sold its shares and is no longer a shareholder of Oi, it 
should not be a part of the mediation. Despite Oi’s position, the RJ Court issued a decision ordering the mediation to be initiated. 

In addition, on March 7, 2018, Oi’s board of directors elected Carlos Augusto Machado Pereira de Almeida Brandão to serve as 

chief financial officer and investor relations officer; he had previously been serving in this position on an interim basis. 

Pursuant to the RJ Plan, Oi was required to engage a human resources consultant to assist with the selection of an operating 
officer. This process concluded on March 23, 2018 with the election by Oi’s board of directors of José Claudio Moreira Gonçalves to 
serve on Oi’s board of executive officers as Oi’s Chief Operating Officer. In addition, on that date, Oi’s board of directors elected 
Bernardo Kos Winik to Oi’s board of executive officers and the newly created position of Chief Commercial Officer. 

On March 7, 2017, João do Passo Vicente Ribeiro resigned as a member of Oi’s board of executive officers. 

For information about the current members of Oi’s board of directors and board of executive officers, see “Item 6. Directors, 

Senior Management and Employees.” 

Settlement of Africatel Arbitration Sale of Interest in MTC 

On June 16, 2016, our wholly-owned subsidiaries PT Participações and Africatel GmbH & Co. KG, or Africatel KG, and our 75%

-owned subsidiary Africatel Holdings B.V., or Africatel BV, entered into a series of agreements with Samba Luxco S.à r. l., or Samba 
Luxco, an affiliate of Helios Investors L.P. and the owner of the remaining 25% of Africatel BV, with the primary purpose of settling 
the arbitral proceedings commenced in the International Court of Arbitration of the International Chamber of Commerce against 
Africatel KG in November 2014. Samba Luxco brought these proceedings in an effort to enforce a put right under a shareholders 
agreement between Samba Luxco and Africatel KG with respect to their holdings in Africatel BV, which we refer to as the Africatel 
shareholders agreement, that Samba Luxco claimed that it was entitled to exercise as a result of our acquisition of PT Portugal in May 
2014. 

The agreements entered into on June 16, 2016 included an amendment to the Africatel shareholders agreement and a Settlement 

and Share Exchange Agreement, which we refer to as the Settlement Agreement, under which Samba Luxco agreed, upon the 
implementation of the Settlement Agreement: (1) to terminate the ongoing arbitration proceeding and release our subsidiaries from all 
past and present claims related to alleged breaches of the Africatel shareholders agreement asserted in the arbitration proceeding, (2) to 
waive certain approval rights it had under the Africatel shareholders agreement, and (3) to transfer 11,000 shares of Africatel BV to 
Africatel BV, resulting in a decline of Samba Luxco’s stake in Africatel BV from 25% to 14%. In exchange, Africatel BV agreed to 
transfer to Samba Luxco its stake in the capital of Mobile Telecommunications Limited, a the telecommunications operator in Namibia, 
or MTC, which represented approximately 34% of the share capital of MTC.

On January 31, 2017, the transactions provided for in the Settlement Agreement were completed. As a result, Samba Luxco 
reduced its stake in Africatel BV to 14,000 shares and Africatel BV transferred to Samba Luxco its stake in MTC. On March 29, 2017, 
Africatel KG and Samba Luxco adopted a shareholders’ resolution under which the 11,000 Africatel BV shares that Samba Luxco had 
transferred to Africatel BV were cancelled and an additional 1,791 Africatel BV shares held by Samba Luxco were cancelled, as a result 
the stakes of Africatel KG and Samba Luxco in Africatel BV are 86% and 14%, respectively. 

Acquisition of A.R.M. 

We had entered into a services agreement with A.R.M. Engenharia Ltda., or A.R.M. Engenharia, in October 2012 for installation, 
operation and corrective and preventive maintenance in connection with our external plant and associated equipment, public telephones, 
and fiber optic and data communication networks (including broadband access services) in the States of Maranhão, Piauí, Ceará, Rio 
Grande do Norte, Paraíba, Pernambuco, Alagoas, Sergipe, Bahia, Amazonas, Roraima, Pará, Amapá, Rio Grande do Sul, Paraná and 
Santa Catarina. 

In April and May 2016, we acquired A.R.M. Engenharia’s operations in the States of Rio Grande do Sul, Santa Catarina and 
Paraná, and we are managing those operations through our subsidiary Serede Serviços de Rede S.A., or Serede. Also in May 2016, we 
entered into an agreement with the shareholders of A.R.M. Engenharia to acquire the totality of the shares issued by A.R.M Engenharia. 
The transaction was concluded on June 27, 2016, after satisfaction of the conditions precedent provided in contract, common in 
transactions of the same nature, including the conclusion of legal and financial audit at A.R.M. Engenharia and the obtainment of 
approval by the Administrative Council for Economic Defense (CADE—Conselho Administrativo para Defesa Econômica). On the 
same date, the corporate name of A.R.M. Engenharia was changed to Rede Conecta – Serviços de Rede S.A., or Rede Conecta. 

For more information about our network maintenance agreements with Serede and Rede Conecta, see “Item 4. Information on the

In addition, we have authorizations to provide fixed-line local telecommunications services in Region III. 

Region I consists of 16 Brazilian states located in the northeastern and part of the northern and southeastern regions. Region I 
covers an area of approximately 5.4 million square kilometers, which represents approximately 64% of the country’s total land area and 
accounted for 31.2% of Brazil’s GDP in 2016. The population of Region I was 112.9 million as of 2016, which represented 54.3% of 
the total population of Brazil as of that date. In 2016, GDP per capita in Region I was approximately R$19,055, varying from R$11,366 
in the State of Maranhão to R$39,827 in the State of Rio de Janeiro. 

Region II consists of the Federal District and nine Brazilian states located in the western, central and southern regions. Region II 
covers an area of approximately 2.8 million square kilometers, which represents approximately 33.5% of the country’s total land area 
and accounted for approximately 26.1% of Brazil’s GDP in 2016. The population of Region II was 49.7 million as of 2016, which 
represented 23.9% of the total population of Brazil as of that date. In 2016, GDP per capita in Region II was approximately R$32,545, 
varying from R$16,953 in the State of Acre to R$73,971 in the Federal District. 

Region III consists of the State of São Paulo. Region III covers an area of approximately 248,000 square kilometers, which 
represents approximately 2.9% of the country’s total land area and accounted for approximately 32.4% of Brazil’s GDP in 2016. The 
population of Region III was 45.1 million as of 2016, which represented 21.7% of the total population of Brazil as of that date. In 2016,

Our business, financial condition, results of operations and prospects depend in part on the performance of the Brazilian economy. 

See “Item 3. Key Information—Risk Factors—Risks Relating to Brazil.” 

Our Services 

We provide a variety of telecommunications services to the residential market, the personal mobility market and the B2B markets 

throughout Brazil. 

Convergent Services 

Recent figures show that bundled offerings build customer loyalty and serve to reduce churn rates as compared to standalone 
services. For example, during the year ended December 31, 2017, the average customer churn rate of customers who purchased our Oi 
Total Residencial triple-play residential bundle that combines fixed-line voice, broadband data and Pay-TV was 36.6% lower than the 
churn rate recorded for customers who purchased our standalone residential fixed-line voice offering. Certain bundles offer incentives 
such as free installation of fixed-line and broadband services, free modem and Wi-Fi and access to certain smartphone applications free 
of charge. We believe that a bundle that contains more services can be more appealing to a customer than, for example, standalone 
broadband services at faster speeds. Both Claro and Telefônica Brasil offer broadband services at higher speeds than us. By developing 
unique, multi-product bundles with joint installation, integrated billing and unified customer service, we set ourselves apart from other 
service providers. We believe that being at the forefront of multi-product offerings allows us to remain competitive, maintain our 
customers’ loyalty and provide higher-value services. 

Oi Total 

In 2015, we launched Oi Total, a bundle designed to increase our market penetration and profitability by attracting new customers 

and offering a higher number of servicers per user. Oi Total embodies our convergence strategy, bringing a unique, complete and 
convenient experience for our customers by offering a single sale, joint installation, integrated billing in a single bill, and unified 
customer service. The integrated processes of Oi Total have allowed us to generate greater operational efficiencies, thereby reducing 
our operating costs. By December 31, 2015, Oi Total had been launched in 13 Brazilian states (Espírito Santo, Goiás, Mato Grosso do 
Sul, Mato Grosso, Acre, Amazonas, Rondônia, Roraima, Tocantins, Rio Grande do Norte, Sergipe, Santa Catarina and Ceará) and the 
Federal District. In March 2016, we launched Oi Total in the remaining Brazilian states where we offer fixed-line services. As of 
December 31, 2017 and 2016, 22.9% and 9.0%, respectively, of our fixed-line customers subscribed to one of the plans in our Oi Total
portfolio. 

Our Oi Total portfolio consists of: 

•

•

•

•

•

Oi Total Solução Completa, our quadruple-play bundle that combines fixed-line voice, broadband data, Pay-TV and mobile 
voice and data services, including (1) unlimited local and domestic long-distance calls from one fixed line and one mobile 
device to any fixed line or mobile device in Brazil, (2) between 10 Mbps and 35 Mbps of broadband data through VDSL, 
(3) between 2GB and 10 GB of 4G mobile data and up to 10 GB of lower speed mobile data, (4) between 125 and 200 
channels of Pay-TV, including between 27 and 75 high-definition, or HD, channels and (5) an extensive on-demand movie, 
TV and internet content that is available free of charge for streaming anytime, anywhere through Oi Play, our content 
platform. In addition, all Oi Total Solução Completa customers receive access to our Wi-Fi access points. 

Oi Total Conectado, our triple-pay bundle that combines fixed-line voice, broadband data and mobile voice and data 
services, including all of the features of the Oi Total Solução Completa plans except for Pay-TV. 

Oi Total Residencial, our residential bundle that combines fixed-line voice, broadband data and Pay-TV, including all of the 
features of the Oi Total Solução Completa plans except for mobile voice and data services. 

Oi Total TV + Fixo, a bundle that combines fixed-line voice and Pay-TV, including unlimited local and domestic long-
distance calls from one fixed line to any fixed-line telephone in Brazil and between 125 and 200 channels of Pay-TV, 
including between 27 and 75 HD channels and a range of Oi Play content. Oi Total TV + Fixo plans include the option to 
add mobile voice services. 

Oi Total Play, a bundle that combines fixed-line voice and broadband data, including unlimited local and domestic long-
distance calls from one fixed line to any fixed-line telephone in Brazil, up to 35 Mbps of broadband data through VDSL and 
a range of Oi Play content. We launched Oi Total Play in 2017. Oi Total Play is a pioneer in the Brazilian market, since it 
provides video content that can be accessed by various devices, using the Oi Play platform, without the need to subscribe for 
a Pay-TV package.

Residential Services 

Our primary services to the residential market are fixed-line voice, broadband data and Pay-TV services. We offer these services 

on an a la carte basis and as bundles, including bundles with other services including our mobile voice services and our mobile data 
communications services. In the Residential Services business, we view the household, rather than an individual, as our customer, and 
our offerings, particularly our bundled offerings, are designed to meet the needs of the household as a whole. 

As of December 31, 2017, our Residential Services segment recorded 15,885 thousand RGUs, as follows: 9,233 thousand fixed 

lines in service; 5,156 thousand broadband RGUs; and 1,496 thousand Pay-TV RGUs. As of December 31, 2016, our Residential 
Services segment recorded 16,425 thousand RGUs, as follows: 9,947 thousand fixed lines in service; 5,188 thousand broadband RGUs; 
and 1,290 thousand Pay-TV RGUs. 

Bundled Services 

Our bundled offerings for residential customers have focused on increasing our profitability by providing a more comprehensive 
mix of higher-value services to our customers. In 2017, we continued to focus our efforts on upselling and cross-selling our services to 
existing customers, enhancing existing customer loyalty and attracting new customers by offering higher-value services such as the Oi 
Total Play bundle within our Oi Total portfolio. We believe that these measures, together with our simplified plan offerings in the 
Residential Services business, resulted in an ARPU increase for our residential services from R$77.2 in 2016 to R$81.3 in 2017. 

In addition to Oi Total, bundles for residential customers include: 

Oi Conta Total 

With the nationwide launch of Oi Total in March 2016, we discontinued new sales of Oi Conta Total, our former triple-play plan 

that combined fixed-line voice, broadband and mobile voice and data services and unlimited text messages to subscribers of any 
provider. We have since moved these offerings under the Oi Total portfolio under the Oi Total Conectado plan and have begun efforts 
to migrate our legacy Oi Conta Total customers to Oi Total. As of December 31, 2017 and 2016, 2.6% and 7.4%, respectively of our 
fixed-line customers subscribed to one of the plans in the Oi Conta Total portfolio. 

Pay-TV and Broadband Bundles 

Subscribers to our internet protocol Pay-TV, or IP TV, service may subscribe to our Oi TV Mais HD package, together with a 

broadband subscription at 100 Mbps, or our Oi TV Mega HD package, together with a broadband subscription at 200 Mbps. 
Subscriptions to our IP TV packages are only available in areas in which we have deployed our fiber-to-the-home, or FTTH, network. 

In addition to our service bundles, we have a la carte offerings for fixed-line voice, broadband, and Pay-TV services as described 

below. 

Fixed-Line Voice Services 

As of December 31, 2017 and 2016, we had 12.9 million and 13.7 million local fixed-line customers, respectively, in our fixed-

line service areas (including customers of our B2B Services business). Local fixed-line services include installation, monthly 
subscription, metered services, collect calls and supplemental local services. Metered services include local calls that originate and 
terminate within a single local area and calls between separate local areas within specified metropolitan regions which, under ANATEL 
regulations, are charged as local calls. ANATEL has divided our fixed-line service areas into approximately 4,400 local areas. 

Under our concession agreements, we are required to offer two local fixed-line plans to users: the Basic Plan per Minute (Plano 
Básico de Minutos) and the Mandatory Alternative Service Plan (Plano Alternativo de Serviços de Oferta Obrigatória), each of which 
includes installation charges, monthly subscription charges, and charges for local minutes. As of December 31, 2017 and 2016, 14.6% 
and 14.5%, respectively, of our fixed-line customers subscribed to the Basic Plan per Minute or the Mandatory Alternative Service 
Plan.

Calls within Brazil that are not classified as local calls are classified as domestic long-distance calls. We provide domestic long-
distance services for calls originating from fixed-line devices in Region I and Region II through our network facilities in São Paulo, Rio 
de Janeiro and Belo Horizonte and through interconnection agreements with other telecommunications providers, both fixed-line and 
mobile, that permit us to interconnect directly with their networks. We provide international long-distance services originating from 
fixed-line devices in our fixed-line service areas through agreements to interconnect our network with those of the main 
telecommunications service providers worldwide. 

In addition to the Basic Plan per Minute and the Mandatory Alternative Service Plan, we offer a variety of alternative fixed-line 
plans that are designed to meet our customers’ usage profiles. As of December 31, 2017 and 2016, 85.4% and 85.5%, respectively, of 
our fixed-line customers subscribed to alternative plans, including our bundled plans. 

Our Oi Fixo portfolio of fixed-line, voice-only plans provides a range of options, including unlimited on-net or all-net calls from 

fixed-line to fixed-line (depending on the plan), as well as on-net and off-net calls to mobile devices at pre-established rates. 

We own and operate public telephones throughout our fixed-line service regions. As of December 31, 2017 and 2016, we had 

approximately 640,000 and 642,000 public telephones in service, respectively, all of which are operated by pre-paid cards. 

Broadband Services 

We provide broadband services to residential customers in our fixed-line service areas. As of each of December 31, 2017 and 
2016, we offered broadband services in approximately 4,700 municipalities and had 5.7 million broadband customers in our fixed-line 
service areas (including customers of our B2B Services business). We offer ADSL services through ADSL modems installed using our 
customers’ conventional lines, which permit customers to use the telephone line simultaneously with the internet. Customers pay a fixed 
monthly subscription fee, irrespective of their actual connection time to the internet. 

We offer broadband a la carte subscriptions to customers that do not subscribe to our bundled services plans at speeds ranging 

from 2 Mbps to 35 Mbps. To attract customers to this service, we offer new subscribers complementary anti-virus software and cloud 
services, as well as a free wireless router with subscriptions at speeds of 5 Mbps or more. 

We periodically offer promotions designed to encourage our existing broadband customers to migrate to plans offering higher 

speeds and to attract new customers to our broadband services. In some cases, we encourage our customers to migrate to higher 
broadband plans by providing broadband at faster speeds for the same prices as existing plans. This improvement of service without an 
increase in cost furthers our goals of improving the perception of quality of our services, enhancing the customer experience and 
enhancing customer loyalty. 

In September 2015, we launched high-speed VDSL broadband service with offers ranging from 15 to 35 Mbps. With continued 

investments in our broadband network infrastructure, we expect to be able to offer our fixed-line broadband services at even greater 
speeds. 

We continue to strategically invest in areas where we see the greatest potential for sales and growth. Our two primary competitors 

in broadband services, Claro and Telefônica Brasil, both offer broadband at higher speeds than our offerings. As a result, 2017, we 
devoted a substantial portion of our capital expenditures in investments to our network to increase the available broadband speeds and 
quality that we are able to offer in order to attract new customers and enhance the loyalty of our existing customer base, which was a 
significant factor in the increase in our ARPU from broadband services during 2017. 

Pay-TV Services 

We offer Pay-TV services under our Oi TV brand. We deliver Pay-TV services throughout our fixed-line service areas using our 

DTH satellite network. We also deliver Oi TV through our fiber optic network in the cities of Rio de Janeiro, Vilar dos Teles, Duque de 
Caxias and Niteroi, in the State of Rio de Janeiro, and the city of Belo Horizonte, in the State of Minas Gerais. As of December 31, 
2017 and 2016, we had approximately 1.5 million and 1.3 million subscribers, respectively, to our Pay-TV services. As of 
December 31, 2017 and 2016, approximately 16.2% and 13.0%, respectively, of households with our residential services subscribed to 
Oi TV.

We offer four packages of Pay-TV services: (1) Oi TV Start HD with 125 channels, including 27 HD channels, (2) Oi TV Mix HD
with 159 channels, including 53 HD channels, (3) Oi TV Total HD with 190 o 194 channels, including 69 HD channels, and (4) Oi TV 
Total Cinema DVR HD with 200 channels, including 75 HD channels and DVR. Subscribers to each of these packages have the option 
to customize the package through the purchase of additional channels featuring films offered by HBO/Cinemax and Telecine and sports 
offered by Futebol. 

Personal Mobility Services 

Our Personal Mobility Services business is comprised of post-paid and pre-paid mobile voice services and post-paid and pre-paid 

mobile data communications services. As of December 31, 2017, we had approximately 36.6 million subscribers (RGUs) for our mobile 
services, of which 29.9 million, or 81.6%, were pre-paid subscribers and 5.7 million, or 18.4%, were post-paid subscribers. As of 
December 31, 2016, we had approximately and 39.9 million subscribers (RGUs) for our mobile services, of which 33.0 million, or 
82.8%, were pre-paid subscribers and 6.9 million, or 17.2%, were post-paid subscribers. Our mobile ARPU increased from R$13.1 in 
2016 to R$14.6 in 2017. 

Our principal mobile services plans are voice and data bundles: Oi Mais for the post-paid market; Oi Livre for the pre-paid market; 

and Oi Mais Controle as a hybrid solution. These offerings are part of our convergence strategy as these plans combine voice and data 
packages across our entire portfolio. This combination of voice and data packages encourages our customers to maintain voice services 
as part of their packages, which reduces that rate of decline of our customer base for fixed-line voice services. In addition, since our 3G 
and 4G networks offer greater capacity to meet the growing demand for data, we intend to accelerate the migration of users from 2G to 
3G and from 3G to 4G by encouraging sales of 3G/4G smartphones and by including more data allowances in our new mobile offers. 
We believe these measures will enhance our customers’ experience and provide a better perception of the quality of our services. 

Mobile Voice and Data Bundles 

Post-Paid 

Customers of our post-paid voice and data bundles are billed on a monthly basis for contracted services used during the previous 
month, in addition to surplus usage and special services contracted and used and monthly subscription fees. In addition to mobile voice 
and mobile data communications services, our post-paid voice and data bundles provide voice mail, caller ID, conference calling, call 
forwarding, calls on hold and other services.

We offer post-paid voice and data bundles through our Oi Mais portfolio. Our Oi Mais plans offer between 7 GB and 50 GB of 4G 

mobile data with no usage restrictions and, since December 2017, unlimited minutes to call fixed-line and mobile customers of any 
operator in Brazil. We believe that our Oi Mais plans allow us to satisfy the growing demand from our customers for unlimited voice 
calls and increased and unrestricted data usage. In addition, all Oi Mais customers receive access to our Oi Play platform and Wi-Fi 
access points. As of December 31, 2017 and 2016, Oi Mais accounted for 32% and 65%, respectively, of our total post-paid mobile 
customer base. 

Since December 2017, all of our post-paid mobile plans include unlimited all-net voice minutes for calls within Brazil, and by the 

end of 2017, approximately 28% of our post-paid customer base had subscribed to one of our unlimited all-net voice options. We 
believe that our offerings in the post-paid market will enable us to improve revenue and market share by offering a mix of services to 
the post-paid market at more attractive prices. 

Pre-Paid 

Pre-paid customers activate their cellular numbers through the purchase and installation of a SIM card in their mobile handsets. 
Our pre-paid customers are able to add credits to their accounts through point-of-sale machines, ATMs, Apple and Android applications 
installed on their mobile devices such as Minha Oi and Recarga Oi using a credit card, our toll-free number or the purchase of pre-paid 
cards at a variety of prices. These credits are valid for a fixed period of time following activation and can be extended when additional 
credits are purchased. 

We offer pre-paid voice and data bundles through our Oi Livre portfolio. Our Oi Livre portfolio includes a range of all-net voice 
minutes for calls within Brazil (including unlimited minutes through the Oi Livre Ilimitado plans) and data allowances (ranging from 
500 MB to 7.6 GB of 4G mobile data) for flat fees. Customers choose the amount of time they have to use their voice and data 
allowances, ranging from one to 30 days. Using the Minha Oi application on their smartphones, customers can freely switch between 
their data and voice allowances depending on their individual needs using a pre-determined exchange rate. Oi Livre changed the mobile 
service market in Brazil, disrupting the original pre-paid model in which customers acquired SIM cards from different operators and 
used the respective SIM card for on-net calls with that particular operator in an effort to avoid paying high rates for off-net calls. The 
launch of Oi Livre in 2015 was a strategic move given the reductions in interconnection tariffs in Brazil. It also follows a global trend 
and adopts a model widely used in developed markets such as the United States and Europe. In addition, we believe the increase in data 
allowances satisfies the growing customer demand for larger data packages that allow access to the great variety of applications 
available for smartphones. As of December 31, 2017 and 2016, Oi Livre accounted for approximately 65.5% and 44.7%, respectively, 
of our total pre-paid base. 

Under our pre-paid voice plans, our customers may also exchange the credits they purchase for additional services, such as: 
(1) Bônus Extra, which permits our customers to purchase additional minutes for local or long-distance calls to our fixed-line or mobile 
subscribers at discounted rates; (2) Pacote de Dados, which permits our customers to purchase a specified data allowance for use on 
their handsets; and (3) Pacote de SMS, which permits our customers to purchase the ability to send a specified number of text messages. 

In keeping with our focus on cost control and increasing profitability, throughout 2017 we disconnected inactive users of our 

pre-paid plans, which reduced FISTEL taxes, which are calculated based on the number of our active subscribers, resulting in an 
increase in the profitability of our customer base. We intend to continue to disconnect inactive users periodically. 

Hybrid 

The hybrid voice services market presents strategic value for our company because it combines advantages of pre-paid offerings, 

such as the absence of bad debt and a favorable impact on working capital, with advantages of post-paid offerings, such as a heavier 
consumption profile. We improve our revenues and market share through the offer of hybrid plans by consolidating customer recharges 
in our hybrid plans’ SIM cards and by improving the mix of offerings to the post-paid market. 

We offer the Oi Mais Controle portfolio of plans for customers who wish to combine the cost savings of our post-paid plans with 
the self-imposed limits of our pre-paid plans. Oi Mais Controle subscribers have similar benefits as the Oi Mais customers, such as data 
packages with no usage restrictions, unlimited text messaging and unlimited all-net voice minutes for calls within Brazil, combined with 
the ability of Oi Livre customers to freely switch between their data and voice allowances depending on their individual needs using a 
pre-determined exchange rate using the Minha Oi application on their smartphones. We believe these data packages, which contain 
more data and no usage restrictions, will allow us to satisfy the growing demand from our customers for increased and unrestricted data 
usage. As of December 31, 2017 and 2016, Oi Mais Controle accounted for approximately 51% and 62%, respectively, of our total 
hybrid mobile customer base.

Mobile Voice Only Services 

We no longer sell voice-only mobile plans. However, we offer mobile voice plans for our pre-paid and hybrid customers who wish 

to purchase additional voice minutes. 

Mobile Data Only Services 

We offer post-paid mobile data communications services to customers who seek to access the internet through our network using 

mobile devices, including smartphones or tablets and laptop computers with the aid of a mini-modem. 

Post-Paid 

As with our Oi Mais customers, our post-paid mobile internet customers pay a monthly subscription fee and are billed on a 
monthly basis for services provided during the previous month, and we throttle the speed of service for customers who exceed their data 
allowances. We also offer internet access for a daily fee to customers who do not subscribe to a monthly plan. 

We offer a variety of post-paid mobile data communications plans that provide data allowances from 3 GB to 30 GB for 

smartphones and from 2 GB to 10 GB for tablets and laptop computers and provide data transmission at speeds of 1 Mbps (3G network) 
or 5 Mbps (4G network). In addition to data traffic, our post-paid mobile internet plans for use with mobile devices include allowances 
for text messages. Our post-paid mobile internet plans for smartphones are available to our Oi Mais customers who wish to purchase 
additional data and to customers of our legacy post-paid stand-alone voice plans who wish to add mobile data services to their 
smartphones. Our post-paid mobile internet plans for tablets and laptop computers are sold on a stand-alone basis or, in some cases, 
through our voice and data bundles. Subscribers to our post-paid mobile internet plans for smartphones, tablets and laptop computers 
also receive free access to our network of Wi-Fi hotspots. In addition to these post-paid plans, subscribers can purchase anti-virus 
software and backup data storage services. 

Pre-Paid and Hybrid 

We also offer mobile data communications services through smartphones for our Oi Livre (pre-paid) and Oi Mais Controle
(hybrid) customers who wish to purchase additional data and to customers of our legacy pre-paid and hybrid stand-alone voice plans 
who wish to add mobile data services to their smartphones. 

Value-Added Services 

The value-added services we provide include voice, text and data applications, including voicemail, caller ID, and other services, 

such as personalization (video downloads, games, ring tones and wallpaper), text messaging subscription services (horoscope, soccer 
teams and love match), chat, mobile television, location-based services and applications (mobile banking, mobile search, email and 
instant messaging). Applications such as the ones described below contributed an increase in revenues from value-added services during 
2017. 

Oi Apps Club: A subscription-based marketplace for highly rated Android apps, Oi Apps Club provides customers unlimited 

access to download apps, charged to the customer’s Oi bill rather than a credit card. 

Oi Conselheiros: In this service, renowned and famous professionals in different areas of expertise known as “Oi’s Ambassadors” 

endorse exclusive content covering travel, fashion, cooking, celebrities and music, among others. 

Oi Para Aprender: Oi’s mobile learning platform, which provides a variety of courses and tips regarding languages, entrance 

examinations, job assessments, how to develop a home office business and software lessons, among others. 

Our value-added services are developed by third-party application or content providers and offered to our customers.

In our B2B Services business, we serve SME and corporate (including government) customers and other telecommunications 
providers. We offer a variety of services to our SME and corporate customers, including our core fixed-line, broadband and mobile 
services, as well as our value-added services, advanced voice services and commercial data transmission services. For our corporate 
customers, we also offer information technology services, such as network management and security, Storage, Smartcloud, anti-
distributed denial of service and machine-to-machine products, which enable communication between a product and its control center or 
database (such as a car and its GPS navigation system), in order to expand our revenue sources from corporate customers beyond voice 
services, increase customer loyalty and ensure greater revenue predictability. We also provide wholesale interconnection, network usage 
and traffic transportation services to other telecommunications providers. 

As of December 31, 2017, our B2B Services segment recorded 6,512 thousand RGUs, as follows: 3,641 thousand fixed lines in 

service; 543 thousand broadband RGUs; 2,316 thousand mobile RGUs; and 12 thousand Pay-TV RGUs. As of December 31, 2016, our 
B2B Services segment recorded 6,617 thousand RGUs, as follows: 3,760 thousand fixed lines in service; 553 thousand broadband 
RGUs; 2,290 thousand mobile RGUs; and 13 thousand Pay-TV RGUs. 

The implementation of certain initiatives since the end of 2015, coupled with the declining macroeconomic conditions in Brazil, 
has prompted certain changes in our portfolios and recent offerings. SMEs are more vulnerable to economic instability than our more 
established corporate customers, so there has been a reduction in our SME customer base as a result of SMEs going out of business. Our 
corporate customers, while better able to survive the current economic instability, often respond by reducing their economic activity and 
tightening their budgets for telecommunications products and services. 

In addition, in a move to better align our products with the needs of our consumers, and to increase customer satisfaction, we have 

taken a “back-to-basics” approach to product and service offerings and, as a result, developed simpler, more predictable flat-rate plans 
that enable the customer to better understand, project and plan for upcoming expenses. Furthermore, our sales focus has shifted to 
upgrading existing contracts, which has not required us to make any additional investments. 

Services for SMEs 

We offer SME services similar to those offered to our residential and personal mobility customers, including fixed-line and mobile 

voice services, and fixed-line and mobile broadband services. We also launched FTTH plans for SMEs. In addition, we offer SMEs: 

•

•

•

advanced voice services, primarily 0800 (toll free) services, as well as voice portals where customers can participate in real-
time chats and other interactive voice services; 

dedicated internet connectivity and data network services; and 

value-added services, such as help desk support that provides assistance for technical support issues, web services with 
hosting, e-mail tools and website builder and security applications. 

In general, our sales team works with our SME customer to determine that customer’s telecommunications needs and negotiates a 
package of services and pricing structure that is best suited to its needs. In December 2015, we launched Oi Mais Empresas for SMEs. 
Oi Mais Empresas provides a portfolio of flat fee services. This simplified portfolio is easier to understand, purchase and use, fostering 
a better relationship with the SME. The flat rate model eliminates billing issues and disputes and reduces the risk of default by the SME. 
Concurrently, as part of our digitalization efforts, we launched the Oi Mais Empresas app, a fully digital customer channel through a 
smartphone application. The Oi Mais Empresas app provides exclusive service to SMEs, enabling them to acquire services, upgrade 
their contract plan and make requests and track the status of those requests, such as repairs and bill copies, among others, all using a 
smartphone. We made the same improvements and enabled the same functionalities as the Oi Mais Empresas app on our website, 
enabling our customers to perform the same functions from a computer. The creation of the Oi Mais Empresas app and website 
improvements changed the way our customers communicate and reinforced our commitment to simplify our product portfolios and 
better understand our customers’ needs.

Services for Corporate Customers 

We offer corporate customers all of the services offered to our SME customers. In addition, we provide a variety of customized, 

high-speed data transmission services through various technologies and means of access to corporate customers. Our principal data 
transmission services for Corporate customers are: 

•

•

•

we act as the internet service provider for our Corporate customers, connecting their networks to the internet; 

dedicated Line Services (Serviços de Linhas Dedicadas), or SLD, under which we lease dedicated lines to corporate 
customers for use in private networks that link different corporate websites; and 

IP services which consist of dedicated internet connection, as well as Virtual Private Network, or VPN, services that enable 
our customers to connect their private intranet and extranet networks to deliver videoconferencing, video/image transmission 
and multimedia applications. 

We provide these services at data transmission speeds of 2 Mbps to 100 Gbps. 

We also offer information technology infrastructure services to our corporate customers, seeking to offer them end-to-end 

solutions through which we are able to provide and manage their connectivity and information technology needs. For example, we offer 
Oi SmartCloud, a suite of data processing and data storage services that we perform through our five cyber data centers located in 
Brasília, São Paulo, Curitiba and Porto Alegre. In addition, through these data centers, we provide hosting, collocation and IT 
outsourcing services, permitting our customers to outsource their IT infrastructures to us or to use these centers to provide backup for 
their IT systems. 

We also offer the following four major service groups through Oi SmartCloud, which operate through our five cyber data centers: 

•

•

•

•

•

collaborative solutions, a hosting and sharing platform that provides employees with access to company documents; 

business applications, an in-memory computing platform for large amounts of data; 

Oi Gestão Mobilidade, a mobile device management service focused on providing logistics and security solutions relating to 
mobile devices; 

Security services, a centralized, anti-spam filtering solution for corporate email; and 

Telepresence as a Service (TPaaS), a video-conferencing service that allows collaboration among people at remote locations. 

We also offer various services based on IT applications: 

•

•

•

•

fleet management services, which provide a management system for fleet monitoring and location targeting, economies of 
scale for fuel costs, driver profile analysis and kilometer control for maintenance; 

Interação Web, a digital marketing service, which allows us to implement on the website of our B2B Services customers an 
intelligent interaction with their digital users in real time. 

workforce management, which provides a system with web and mobile applications to monitor and control the workforce in 
the field and optimize routes and control logistics activities; and 

digital content management (corporate TV platform and queue management), which provides a digital signage platform with 
queue management solutions, creating a powerful marketing tool for companies that have interactions with customers at 
points of sale. 

In order to provide complete solutions to our corporate clients, we have entered into service agreements for the joint supply of 

international data services with a number of important international data services providers. These commercial relationships with 
international data services providers are part of our strategy of offering telecommunications services packages to our customers. 

Wholesale Services 

We offer specialized wholesale services to other telecommunications providers, primarily consisting of interconnection to our 

networks, network usage charges for the use of portions of our long-distance network, traffic transportation through our physical 
infrastructure, and RAN sharing agreements.

Interconnection and Network Usage Charges 

All telecommunications services providers in Brazil are required, if technically feasible, to make their networks available for 

interconnection on a non-discriminatory basis whenever a request is made by another telecommunications services provider. 
Interconnection permits a call originated on the network of a requesting local fixed-line, mobile or long-distance service provider’s 
network to be terminated on the local fixed-line or mobile services network of the other provider. 

We are authorized to charge for the use of our local fixed-line network on a per-minute basis for (1) all calls terminated on our 
local fixed-line networks in Regions I and II that originate on the networks of other mobile and long-distance service providers, and 
(2) all long-distance calls originated on our local fixed-line networks in Regions I and II that are carried by other long-distance service 
providers. 

Conversely, other local fixed-line service providers charge us interconnection fees (1) to terminate calls on their local fixed-line 

networks that are originated on our mobile or long-distance networks, and (2) for long-distance calls originated on their local fixed-line 
networks that are carried by our long-distance network. 

In addition, we charge network usage fees to long-distance service providers and operators of trunking services that connect 

switching stations to our local fixed-line networks. We are authorized to charge for the use of our long-distance network on a 
per-minute basis for all calls that travel through a portion of our long-distance networks for which the caller has not selected us as the 
long-distance provider. Conversely, other long-distance service providers charge us interconnection fees on a per-minute basis for all 
calls that travel through a portion of their long-distance networks for which the caller has selected us as the long-distance provider. 

We are authorized to charge for the use of our mobile network on a per-minute basis for all calls terminated on our mobile 
network that originate on the networks of other local fixed-line, mobile and long-distance service providers. Conversely, other mobile 
services providers charge us interconnection fees to terminate calls on their mobile networks that are originated on our local fixed-line, 
mobile or long-distance networks. The amounts that we charge and owe for these interconnections with respect to SMEs have reduced 
dramatically, however, as a result of the recent reductions in interconnection tariffs mandated by ANATEL. The pricing for services to 
our corporate customers are not immediately affected by the ANATEL reductions. Rather, these rate reductions are only reflected in the 
negotiation and pricing of new contracts. 

Transportation 

We provide Industrial Exploitation of Dedicated Lines (Exploração Industrial de Linha Dedicada), or EILD, services under which 
we lease trunk lines to other telecommunications services providers, primarily mobile services providers, which use these trunk lines to 
link their radio base stations to their switching centers. 

Long-distance and mobile services providers may avoid paying long-distance network usage charges to us by establishing an 

interconnection to our local fixed-line networks. In order to retain these customers of our long-distance services, we offer a long-
distance usage service, called national transportation, under which we provide discounts to our long-distance network usage fees based 
on the volume of traffic and geographic distribution of calls generated by a long-distance or mobile services provider. 

We also offer international telecommunications service providers the option to terminate their Brazilian inbound traffic through 
our network, as an alternative to Claro and TIM. We charge international telecommunications service providers a per-minute rate, based 
on whether a call terminates on a fixed-line or mobile telephone and the location of the local area in which the call terminates. 

Rates 

Our rates for certain services, including basic local fixed-line and domestic long-distance plans, interconnection, EILD and SLD 
services, are subject to regulation by ANATEL, subject to certain exceptions. For information on ANATEL regulation of our rates, see 
“—Telecommunications Regulation—Regulation of the Brazilian Telecommunications Industry.” Under our current authorizations, 
which we operate under the private regime, we are allowed to set prices for our mobile service plans, provided that such amounts do not 
exceed a specified inflation adjusted cap. Other telecommunications services, such as broadband services, IP services, frame relay 
services and DTH and IP TV are not subject to ANATEL regulation. 

Many of the services we provide charge on a per-minute basis. For these services, we charge for calls based on the period of use. 

The charge unit is a tenth of a minute (six seconds), and rounding is permitted to the next succeeding tenth of a minute. There is a 
minimum charge period of 30 seconds for every call. For local fixed-line to fixed-line calls during off-peak hours, charges apply on a 
per-call basis, regardless the duration of the call.

Our revenues from local fixed-line services consist mainly of monthly subscription charges, charges for local calls and charges for 

the activation of lines for new subscribers or subscribers that have changed addresses. Monthly subscription charges are based on the 
plan to which the customer subscribes and whether the customer is a residential, commercial or trunk line customer. 

Under our concession agreements, we are required to offer two local fixed-line plans to users: the Basic Plan per Minute and the 
Mandatory Alternative Service Plan, each of which includes installation charges, monthly subscription charges, and charges for local 
minutes. The monthly subscription fees under the Basic Plan per Minute and the Mandatory Alternative Service Plan vary in accordance 
with the subscribers’ profiles, as defined in the applicable ANATEL regulations. As of December 31, 2017 and 2016, 14.6% and 
14.5%, respectively, of our fixed-line customers subscribed to the Basic Plan per Minute or the Mandatory Alternative Service Plan 

In addition to the Basic Plan per Minute and the Mandatory Alternative Service Plan, we are permitted to offer non-discriminatory 

alternative plans to the basic service plans. The rates for applicable services under these plans (e.g., monthly subscription rates and 
charges for local and long-distance calls) must be submitted for ANATEL approval prior to offering those plans to our customers. In 
general, ANATEL does not raise objections to the terms of these plans. As of December 31, 2017 and 2016, 85.4% and 85.5%, 
respectively, of our fixed-line customers subscribed to alternative plans, including our bundled plans. 

On an annual basis, ANATEL increases or decreases the maximum rates that we are permitted to charge for our basic service 
plans. ANATEL increased the rates that we may charge by an average of 3.6% as of June 13, 2015 and 2.94% as of September 12, 
2016, and decreased the rates that we may charge by an average of 0.08% as of November 11, 2017. In addition, we are authorized to 
adjust the rates applicable to our alternative plans annually by no more than the rate of inflation, as measured by the 
Telecommunications Services Index (Índice de Serviços de Telecomunicações – IST), or IST. Discounts from the rates set in basic 
service plans and alternative service plans may be granted to customers without ANATEL approval. 

Local Fixed Line-to-Mobile Rates (VC-1) and Mobile Long Distance Rates (VC-2 and VC-3) 

When one of our fixed-line customers makes a call to a mobile subscriber of our company or another mobile services provider that 
terminates in the mobile registration area in which the call was originated, we charge our fixed-line customer per-minute charges for the 
duration of the call based on rates designated by ANATEL as VC-1 rates. In turn, we pay the mobile services provider a per-minute 
charge based on rates designated by ANATEL as mobile termination, or MTR, rates for the use of its mobile network in completing the 
call. Rates for long-distance calls that originate or terminate on mobile telephones are based on whether the call is an intrasectorial long-
distance call, which is charged at rates designated by ANATEL as VC-2 rates, or an intersectorial long-distance call, which is charged 
at rates designated by ANATEL as VC-3 rates. If the caller selects one of our carrier selection codes for the call, we receive the 
revenues from the call and must pay interconnection fees to the service providers that operate the networks on which the call originates 
and terminates. VC-1, VC-2 and VC-3 rates, collectively, the “VC Rates” vary depending on the time of the day and day of the week, 
and are applied on a per-minute basis. 

On an annual basis, ANATEL may increase or decrease the maximum VC Rates that we are permitted to charge. As a result of the 

substantial reductions in VC Rates in past years (for example, between 2012 and 2018, ANATEL reduced our VC-1 rate by 
approximately 65%) and in keeping with our strategy of simplifying our portfolios to enhance the customer experience, in 2015 we 
launched several fixed-line and mobile plans that allow all-net calls for a flat fee. In addition, since 2017 most of our mobile plans allow 
our customers to place unlimited local and long-distance calls regardless of the network where the call originates or terminates. All-net 
and unlimited plans eliminate the effect of VC Rate reductions on our customers’ telephone bills and simplify the billing process. 

Fixed Line-to-Fixed-Line Long Distance Rates 

If a caller selects one of our carrier selection codes for a long-distance call that originates and terminates on fixed-line telephones, 
we receive the revenues from the call and must pay interconnection fees to the service providers that operate the networks on which the 
call originates and terminates. Rates for these long-distance calls are based on the physical distance separating callers (which are 
categorized by four distance ranges), time of the day and day of the week, and are applied on a per-minute basis for the duration of the 
call. Rates on these calls are applied on a per-minute basis.

On an annual basis, ANATEL increases or decreases the maximum domestic fixed line-to-fixed line long-distance rates that we 

are permitted to charge. ANATEL increased the rates that our company may charge by an average of 0.7% as of September 9, 2016 and 
decreased such rates by 0.7% as of November 11, 2017. Discounts from the domestic fixed line-to-fixed line long-distance rates 
approved by ANATEL may be granted to customers without ANATEL approval. 

Mobile Rates 

Mobile telecommunications service in Brazil, unlike in the United States, is offered on a “calling-party-pays” basis under which a 
mobile subscriber pays only for calls that he or she originates (in addition to roaming charges paid on calls made or received outside the 
subscriber’s home registration area). A mobile subscriber receiving a collect call is also required to pay mobile usage charges. 

Our revenues from mobile services consist mainly of charges for local and long-distance calls and data packages paid by our 

pre-paid and post-paid mobile subscribers and monthly subscription charges paid by our post-paid plan subscribers. Monthly 
subscription charges are based on a post-paid subscriber’s service plan. If one of our mobile subscribers places or receives a call from a 
location outside of his or her home registration area, we are permitted to charge that customer the applicable roaming rate. We charge 
for all mobile calls made by our pre-paid customers, and for mobile calls made by our post-paid customers in excess of their allocated 
monthly number of minutes, on a per-minute basis. 

Although subscribers of a plan cannot be forced to migrate to new plans, existing plans may be discontinued as long as all 

subscribers of the discontinued plan receive a notice to that effect and are allowed to migrate to new plans within 30 days of such 
notice. 

Rates under our mobile plans may be adjusted annually by no more than the rate of inflation, as measured by the IGP-DI. These 
rate adjustments occur on the anniversary dates of the approval of the specific plans. We may grant customers discounts from the rates 
set in our service plans without ANATEL approval. The rate of inflation as measured by the IGP-DI was 10.7% in 2015, 7.2% in 2016 
and (0.42)% in 2017. 

Network Usage (Interconnection) Rates 

Fixed-Line Networks 

Our revenues from the use of our local fixed-line networks consist primarily of payments on a per-minute basis, which are charged 

at rates designated by ANATEL as TU-RL rates, from: 

•

•

•

long-distance service providers to complete calls terminating on our local fixed-line networks; 

long-distance service providers for the transfer to their networks of calls originating on our local fixed-line networks; and 

mobile services providers to complete calls terminating on our local fixed-line networks. 

Fixed-line service providers are not permitted to charge other fixed-line service providers for local fixed-line calls originating on their 
local fixed-line networks and terminating on the other provider’s local fixed-line networks. TU-RL rates vary depending on the time of 
the day and day of the week, and are applied on a per-minute basis. 

Our revenues from the use of our long-distance networks consist primarily of payments on a per-minute basis, which are charged 
at rates designated by ANATEL as TU-RIU rates, from other long-distance carriers that use a portion of our long-distance networks to 
complete calls initiated by callers that have not selected us as the long-distance provider. TU-RIU rates for intrasectorial calls are 
designated by ANATEL as TU-RIU1 rates, and TU-RIU rates for intersectorial calls are designated by ANATEL as TU-RIU2 rates. 

TU-RIU rates vary depending on the time of the day and day of the week, and are applied on a per-minute basis. Historically, the 

TU-RIU rates of Oi and Telemar have been equal to 20% of their respective domestic fixed line-to-fixed line long-distance rates for 
such calls.

In July 2014, ANATEL published the maximum fixed reference rates, including TU-RL and TU-RIU, for entities with significant 

market power, such as our company, for 2016 through 2019. As a result, our TU-RL and TU-RIU reference rates have declined 
significantly and will continue to decline through 2019, when TU-RL and TU-RIU rates reflecting a methodology that takes into 
consideration all long-run incremental costs, updated to current values, of providing a particular service and the unit costs of such 
service based on an efficient network considering the existing regulatory obligations, will apply. In February 2016, our TU-RL rate in 
each of Region I and II was R$0.01146 per minute, our TU-RIU1 rates in Regions I and II were R$0.06124 per minute and R$0.4946 
per minute, respectively, and our TU-RIU2 rates in Regions I and II were R$0.06621 per minute and R$0.5524 per minute, respectively. 
In each of February 2017 and 2018, our TU-RL rates in Regions I and II declined by 20.9% and 22.8%, respectively, our TU-RIU1 
rates in Regions I and II declined by 52.8% and 45.1%, respectively, and our TU-RIU2 rates declined by 57.3% and 49.9%, 
respectively, and we expect that these rates will decline by the same percentages in 2019. 

Mobile Networks 

Our revenues from the use of our mobile networks consist primarily of payments on a per-minute basis from (1) local fixed-line, 

long-distance and mobile services providers to complete calls terminating on our mobile networks, and (2) long-distance service 
providers for the transfer to their networks of calls originating on our mobile networks. 

The terms and conditions of interconnection to our mobile networks, including the rates charged to terminate calls on these mobile 

networks, which are designated by ANATEL as MTR rates, commercial conditions and technical issues, may be freely negotiated 
between us and other mobile and fixed-line telecommunications service providers, subject to compliance with regulations established 
by ANATEL relating to traffic capacity and interconnection infrastructure that must be made available to requesting providers, among 
other things. We must offer the same MTR rates to all requesting service providers on a nondiscriminatory basis. We apply MTR 
charges on a per-minute basis. 

In December 2013 ANATEL established the maximum MTR rate of R$0.33 per minute that is applicable in the event that 
providers could not agree upon the MTR applicable in their interconnection agreements. Under the General Plan on Competition 
Targets, for the period from February 2015 to February 2016, the MTR rate was reduced to 50% of the maximum MTR rate established 
by ANATEL in December 2013. In July 2014, ANATEL published the maximum MTR reference rates for entities with significant 
market power, such as our company, for 2016 through 2019. As a result, our MTR rates have declined significantly and will continue to 
decline through 2019, when MTR rates reflecting a methodology that takes into consideration all long-run incremental costs, updated to 
current values, of providing a particular service and the unit costs of such service based on an efficient network considering the existing 
regulatory obligations, will apply. In February 2016, our MTR rates in Regions I, II and III were set at R$0.09317 per minute, 
R$0.10308 per minute and R$0.11218 per minute, respectively. In each of February 2017 and 2018, our MTR reference rates in 
Regions I, II and III declined by 47.1%, 47.7% and 39.2%, respectively, and they will decline by the same percentages in February 
2019. 

Data Transmission Rates 

Broadband services, IP services and frame relay services are market driven and not subject to ANATEL regulation. We offer 
broadband services subscriptions at prices that vary depending on the download speeds available under the purchased subscription. 

A significant portion of our revenues from commercial data transmission services are generated by monthly charges for EILD and 

SLD services, which are based on contractual arrangements for the use of part of our networks. Under ANATEL regulations, because 
we are deemed to have significant market power in the fixed-line services business, we are required to make publicly available the 
forms of agreements that we use for EILD and SLD services, including the applicable rates, and are only permitted to offer these 
services under these forms of agreements. ANATEL publishes reference rates for these services and if one of our customers objects to 
the rates that we charge for these services, that customer is entitled to seek to reduce the applicable rate through arbitration before 
ANATEL. 

In July 2014, ANATEL published reference rates for EILD services that contain a single reference table which will be valid from 

2016 until 2020, when rates reflecting a methodology that takes into consideration all long-run incremental costs, updated to current 
values, of providing a particular service and the unit costs of such service based on an efficient network considering the existing 
regulatory obligations, will apply. In addition, under the General Plan of Competition Targets, companies with significant market, such 
as our company, are required to present a public offer every six months including standard commercial conditions, which is subject to 
approval by ANATEL.

Our revenue from IP services is based on the number of data ports to which the customer is granted access. Our revenue from 

frame relay services consists mainly of charges for access to the data transmission network and metered service charges based on the 
amount of data transmitted. Such services are offered as pay-per-use or volume-based packages. Our revenue from cyber data center 
services is generally based on contractual arrangements that are tailored to the specific services provided. 

DTH and IP TV Services Rates 

DTH and IP TV services are deemed to be conditional access services under the private regime, which Oi provides pursuant to 
authorizations. As a result, the rates and prices for these services are not subject to ANATEL regulation and are market-driven. We 
offer DTH and IP TV subscriptions at prices that vary depending on the content of the subscription package. We offer basic 
subscription packages for our Oi TV services, as well as a variety of premium packages which allow subscribers to tailor the content 
that they receive to their individual tastes. 

Marketing and Distribution 

During 2017 and 2016, we incurred R$410 million and R$427 million, respectively, in marketing expenses in our Brazilian 
operations. On a company-wide basis, we focus our marketing efforts on the upscaling of existing clients while strengthening the “Oi” 
brand through our convergent services offerings and promotion of our Minha Oi smartphone application, which allows our pre-paid 
customers to freely switch between their data and voice allowances. We also engage in digital marketing and multiple customer 
relationship management (CRM) marketing programs to support our B2B Services business. 

In 2017, we dramatically increased our investment in digital advertising, which has increasingly grown in relevance as compared 

to more traditional advertising platforms. In combination with television advertising, our digital presence maximizes our return on 
investment in line with our strategy to reach all types and classes of customers and potential customers. We tactically use other media 
outlets, such as radio, billboards and exterior signage, for specific initiatives, while direct mail, text messaging and telemarketing are 
used to upscale our current base. We also sponsor sporting events and individual athletes, as well as cultural events, to increase brand 
awareness and promote our portfolio as a telecommunications provider capable of meeting all of the telecommunications needs of our 
customers. 

Our principal marketing expenditures to support our Residential Services business are designed to: 

•

•

promote our Oi Total bundled plans, as part of our effort to expand our customer base; and 

promote cross-selling of our services by promoting our bundled plans and higher-value offers, as part of our effort to 
generate higher ARPU and reduce customer churn rates. 

Our principal marketing expenditures to support our Personal Mobility Services business are designed to: 

•

•

promote the Minha Oi app, which allows our customers to freely switch between their data and voice allowances, via ad 
campaigns on television and digital media; 

promote our post-paid and hybrid mobile plans, primarily Oi Mais and Oi Mais Controle, as well as 4G data services at 
higher speeds, through specific marketing campaigns and mobile device subsidies (through our Oi Pontos program, which 
provides existing post-paid customers with a phone credit based on amount spent in the preceding 12-month period, to be 
applied as a credit against the price of a new mobile device), as part of our effort to increase our market share in mobile 
services; and 

•

expand our 4G internet customer base, focusing on geographic regions covered by the National Broadband Plan.

We have established separate distribution channels to serve SME and corporate customers. We market a variety of services to 
SMEs, including our core fixed-line, broadband and mobile services, as well as our value-added services, advanced voice services and 
commercial data transmission services. As of December 31, 2017, the principal distribution channels that we use to market our services 
to SMEs were: 

•

•

“Oi” exclusive agents with door-to-door sales consultants that are dedicated to understanding and addressing the 
communications needs of our existing and prospective SME customers; 

our telemarketing sales channel, which consists of three agents that use sales representatives that are specifically trained to 
discuss the business needs of our prospective SME customers to make sales calls, as well as representatives in our call center 
and representatives at call centers under contract with us to receive calls from existing and prospective SME customers to 
sell services to new customers and promote higher-value and additional services to existing customers. In addition, our 
telemarketing channel utilizes customer retention representatives; and 

•

our website and the Oi Mais Empresas application. 

We market our entire range of services to corporate customers through our own direct sales force which meets with current and 

prospective corporate customers to discuss the business needs of these enterprises and design solutions intended to address their 
communications needs. Our client service model focuses on post-sale service and we regularly discuss service needs and improvements 
through calls and meetings with our customers. As of December 31, 2017, our corporate sales team, including post-sale service 
personnel, was composed of approximately 1,390 employees operating in five regional offices. 

Billing and Collection 

Residential Services 

We send each of our Residential Services customers a monthly bill covering all the services provided during the prior monthly 

period. Customers are grouped in billing cycles based on the date their bills are issued. Each bill separately itemizes service packages, 
local calls, long-distance calls, calls terminating on a mobile network, toll-free services and other services such as call waiting, 
voicemail and call forwarding. Payments of Residential Services bills are due within an average of 15 days after the billing date. We 
charge late-payment interest at a rate of 1% per month plus a one-time late charge of 2% of the amount outstanding. We have 
agreements with several banks for the receipt and processing of payments from our Residential Services customers. A variety of 
businesses, such as lottery houses, drugstores and grocery stores, accept payments from our Residential Services customers as agents 
for these banks. As of December 31, 2017, 15.6% of all accounts receivable due from our Residential Services customers in Brazil were 
outstanding for more than 30 days and 12.0% were outstanding for more than 90 days. 

We are required to include in our monthly Residential Services bills charges incurred by our customers for long-distance services 

provided by other long-distance service providers upon the request of these providers. We have billing agreements with each long-
distance telecommunications service provider that interconnects with our networks under which we bill our customers for any long-
distance calls originated on our network that are carried by another long-distance service provider and transfer the balance to the 
relevant provider after deducting any access fees due for the use of our network.

ANATEL regulations permit us to restrict outgoing calls made by a Residential Services customer 15 days after we send the 
customer a past due notice, restrict incoming calls received by a Residential Services customer 30 days after the restriction on outgoing 
calls is imposed, and disconnect a Residential Services customer after 30 days after the restriction on incoming calls is imposed. The 
disconnection process thus comprises several stages, including customer notification regarding the referral of their delinquency to credit 
bureaus, before the Residential Services customer may be ultimately disconnected due to non-payment. Notices range from voice 
messages to active calls for negotiation with the customer. Our collection system enables us to access delinquent subscribers’ accounts 
according to their payment profile. This profile takes into consideration, among other things, the length of subscription, the outstanding 
balance of the account and the longest payment delays. 

Personal Mobility Services 

We bill our post-paid Personal Mobility Services customers on a monthly basis and itemize charges in the same manner as we bill 

our Residential Services customers. In addition, the monthly bills also provide details regarding minutes used and roaming charges. 
Payments are due within an average of 15 days after the billing date. We charge late-payment interest at a rate of 1% per month plus a 
one-time late charge of 2% of the amount outstanding. As with our Residential Services business, we have agreements with several 
banks for the receipt and processing of payments from our post-paid Personal Mobility Services customers. A variety of businesses, 
such as lottery houses, drugstores and grocery stores, accept payments from our post-paid Personal Mobility Services customers as 
agents for these banks. As of December 31, 2017, 34.7% of all accounts receivable due from our Personal Mobility Services customers 
in Brazil were outstanding for more than 30 days and 30.4% were outstanding for more than 90 days. 

ANATEL regulations permit us to restrict outgoing calls made and text messages sent by a post-paid Personal Mobility Services 

customer 15 days after we send the customer a past due notice, restrict incoming calls and text messages received by a post-paid 
Personal Mobility Services customer 30 days after the restriction on outgoing calls and text messages is imposed, and cancel services to 
a post-paid Personal Mobility Services customer after 30 days after the restriction on incoming calls is imposed. The cancellation 
process thus comprises several stages, including customer notification regarding the referral of their delinquency to credit bureaus, 
before services to the post-paid Personal Mobility Services customer may be ultimately cancelled due to non-payment. Notices range 
from text messages to active calls for negotiation with the customer. Our collection system enables us to access delinquent subscribers’ 
accounts according to their payment profile. This profile takes into consideration, among other things, the length of subscription, the 
outstanding balance of the account and the longest payment delays. We have also implemented an information tool to assist with 
account management that is designed to warn subscribers of high outstanding amounts due and unpaid. 

Customers of our pre-paid Personal Mobility Services can only use a paid service if they have enough active credits in their 
accounts to do so. In order to acquire credits, customers must recharge their SIM cards in one of our many points of sales. Services are 
charged directly from the customer´s accounts and are free of bad-debt risk. 

Network and Facilities 

Our Brazilian networks are comprised of physical and logical infrastructures through which we provide fully-integrated services, 

whether fixed-line or mobile, voice, data or image, thereby optimizing available resources. We monitor our networks remotely from our 
centralized national network operations center in Rio de Janeiro. Network operating and configuration platforms, located at the network 
operations center, perform failure monitoring, database and configuration management, security management and performance analysis 
for each network.

Access Networks 

Our Brazilian access networks connect our customers to our signal aggregation and transportation networks. We have a large 

number of network access points, including twisted copper pair wires to residences and commercial buildings, fiber optic lines to 
residences and commercial buildings, wireless transmission equipment and Wi-Fi hotspots. Our fixed-line networks are fully 
digitalized. 

Voice and data signals that originate through fixed-line access points are routed through Multi-service Access Nodes, or MSANs, 

to our aggregation networks, or are rerouted to our aggregation networks through Digital Subscriber Line Access Multiplexer, or 
DSLAM, equipment which split the voice signal from the digital signal which is transmitted using ADSL or VDSL technology. We are 
engaged in a long-term program to update our DSLAM equipment as demand for data services increases. As of December 31, 2017, 
approximately 93% of our fixed-line network had been updated to support ADSL2+ or VDSL2 and we provided ADSL or VDSL2 
services in approximately 4,700 municipalities. 

ADSL technology allows high-speed transmission of voice and data signals on a single copper wire pair for access to the network. 
Since voice transmission through telephone lines uses only one of many available frequency bands, the remaining frequency bands are 
available for data transmission. Our network supports ADSL2+ and VDSL2, or very-high-bitrate digital subscriber line, technologies. 
ADSL2+ is a data communications technology that allows data transmission at speeds of up to 24 Mbps downstream and 1 Mbps 
upstream, which is much faster than data transmission through conventional ADSL. ADSL2+ permits us to offer a wider range of 
services than ADSL, including IP TV. VDSL2 is a DSL technology providing faster data transmission, up to 100 Mbps (downstream 
and upstream), permitting us to support high bandwidth applications such as HDTV, VoIP and broadband internet access, over a single 
connection. 

We are engaged in a long-term program to upgrade portions of our fixed-line access networks with optical fiber networks based on 

gigabit passive optical network, or GPON, technology to support VDSL2 service and facilitate our offering of our Oi TV service. The 
implementation of this technology permits us to provide broadband with speeds up to 100 Mbps to residential customers and up to 1 
Gbps to commercial customers. 

For our non-residential customers, we have a fully integrated and managed network providing access for networks based on 
internet protocol, or IP, and Asynchronous Transfer Mode, or ATM, protocol over legacy copper wire through which are able to 
provide:

•

•

•

symmetric and transparent access to Frame Relay services at speeds from 64 kbps to 1.5 Mbps; 

symmetrical access with PPP (Point to Point) for the Internet connection services at speeds from 64 kbps to 1.5 Mbps; and 

symmetrical access with PPP (Point to Point) to provide connection services for virtual private networks, or VPNs, through 
Multiprotocol Label Switching, or MPLS, protocol at speeds from 64 kbps to 1.5 Mbps. 

The following table sets forth selected information about our fixed-line networks as of the dates and for the periods indicated.

Mobile devices access our GSM (Global System for Mobile Communications), or 2G, mobile networks on frequencies of 900 
MHz/1800 MHz, our 3G mobile networks on frequencies of 2100 MHz and our 4G mobile networks on frequencies of 2500 MHz. Our 
2G access points use General Packet Radio Service, or GPRS, which allows speeds in the range of 115 kilobytes per second (Kbps), and 
Enhanced Data Rates for Global Evolution, or EDGE, which allows speeds in the range of 230 Kbps, to send and receive data signals. 
Our 3G access points use high speed packet access, or HSPA, which allows speeds in the range of 14.2 Mbps, to send and receive data 
signals. Our 4G access points use 10+10 MHz and 2x2 Multiple Input Multiple Output, which allows speeds in the range of 75 Mbps, to 
send and receive data signals. Voice and data signals sent and received through our 2G and 3G access points are routed to our 
aggregation networks. Our mobile networks have unique data core and are fully integrated with our fixed-line data networks. 

As of December 31, 2017, our 2G mobile access networks, consisting of 13,873 active radio base stations, covered 3,407 

municipalities, or 93% of the urban population of Brazil. We have GPRS coverage in 100% of the localities covered and EDGE 
coverage in all state capitals. 

As of December 31, 2017, our 3G mobile access networks, consisting of 10,020 active radio base stations, covered 1,603 

municipalities, or 81% of the urban population of Brazil. We have HSPA coverage in all state capitals. 

As of December 31, 2017, our 4G access networks, consisting of 7,965 active radio base stations, covered 813 municipalities, or 

73% of the urban population of Brazil. 

In addition to these mobile access networks, we also operate Wi-Fi hotspots in indoor public and commercial areas such as coffee 
shops, airports and shopping centers. Since 2012, we have provided outdoor urban wireless networks, including in the neighborhoods of 
Copacabana and Ipanema in the city of Rio de Janeiro. As of December 31, 2017, our Wi-Fi network consisted of more than two 
million hotspots, with broadband access compatible with more than two million access points provided by Fon Wireless Ltd., or Fon, 
which allows our customers to access Fon lines worldwide. 

Aggregation Networks 

Voice and data signals sent through our access network are routed through our aggregation networks to digital switches which 
connect voice calls and route digital signals to their destinations. Portions of our aggregation network use conventional copper trunk 
lines to connect our access network to our switches and transportation networks. For a small portion of our aggregation network, we 
still use ATM protocol to permit high speed transmission of these signals. Other portions of our aggregation network use fiber optic 
cable to connect our access network to our switches and transportation networks using Synchronous Digital Hierarchy, or SDH, 
protocol. In large metropolitan areas where the density of access point results in increased demand, we have deployed Metro Ethernet 
networks. Our Metro Ethernet networks are fully-integrated management systems and provide: 

•

•

•

•

•

ethernet data services from 4 Mbps up to 1 Gbps for point-to-point and multipoint dedicated access; 

ethernet access services from 4 Mbps up to 1 Gbps for IP access and MPLS/VPN access; 

aggregation network services for ADSL2+ and VDSL2 platforms; 

aggregation network services for GPON platforms; and 

DWDM systems for services above 1Gbps to prevent overbooking our Metro Ethernet network. 

In the past, we used ATM protocol to transport digital signals through our access network from non-residential customers that 

require dedicated bandwidth to our switching stations. In response to changing customer needs, we converted elements of our network 
that use ATM and SDH protocols, that permit us to offer dedicated bandwidth to our customers, to MPLS protocol, which supports IP 
and permits the creation of VPNs through our MetroEthernet networks. We now use MPLS-TP capable devices that have been designed 
to interface with our existing Metro Ethernet Network to increase the bandwidth of our networks to support our 4G network data traffic 
and replace our legacy SDH networks.

Transportation Networks 

We have a nationwide long-distance backbone, consisting of an optical fiber network that connects the Federal District and all 

state capitals in Brazil. This fiber network supports high capacity Dense Wavelength Division Multiplex, or DWDM, systems that can 
operate with up to 80 channels at 10 and 40 Gbps. In 2015, we completed the implementation of a new Optical Transport 
Network/DWDM, or OTN/DWDM network, with 100 Gbps links that connect 11 state capitals, including São Paulo, Rio de Janeiro, 
Brasília and Belo Horizonte. This new OTN/DWDM network spreads over approximately 30,000 km of optical cables. Our optical 
network is complemented by microwave links to reach smaller cities and towns. In 2017 we began the extension of the OTN/DWDM 
network, with 100 Gbps links, to an additional seven state capitals. This extension is expected to be completed in the first half of 2018 
and spreads over an additional 18,000 km of optical cables. 

We employ automatic traffic protection to improve the reliability of our network and increase its traffic capacity. The network is 
fully supervised and operated by management systems that allow rapid response to customer service requests and reduce the recovery 
time in case of failures. 

We operate an internet backbone network and a fully IP-routed network, which provides a backbone for all internet dedicated 
services and VPN offerings. Our internet backbone connects to the public internet via international links that we maintain in the United 
States. 

Our transportation network is directly interconnected to the national and international long-distance networks of all long-distance 

service providers operating in Regions I, II and III and all mobile services providers in Regions I, II and III. 

Satellite Network 

We have deployed an expanded range of satellite-based services to comply with our public service obligations to the rural and 

remote areas of Brazil, including the Amazon rainforest region. These satellite services include internet access and access to corporate 
data applications. As of December 31, 2017, our satellite network covered approximately 5,144 localities in 26 states and the Federal 
District and provided voice and data services. 

In 2000, we began the implementation of the land-based segment of our respective satellite networks in order to extend 

transmission to remote areas in the states of Acre, Paraná, Rondônia, Rio Grande do Sul, Santa Catarina, Pará, Amazonas, Amapá and 
Roraima, as well as to other areas with limited access to telecommunications services due to geographical conditions, such as Mato 
Grosso, Mato Grosso do Sul, Goiás and Tocantins. The satellite network comprises satellite earth stations located in less-populated rural 
areas, as well as hub stations in the cities of Brasília, Manaus, Boa Vista, Macapá, Belém, Santarém, Marabá, Rio de Janeiro and Porto 
Velho. These satellite networks use digital technology and began operating in August 2000. The fiber optic and satellite backbones are 
interconnected in Brasília, Belém, Manaus, Rio de Janeiro and Porto Velho. The integration of the land-based segment of our satellite 
network allows us to provide fixed-line and mobile voice service to our subscribers in any location in our fixed-line service areas. 

Hispamar Satellite S.A., or Hispamar, a Spanish-Brazilian consortium created in November 1999 by Hispasat (the leading satellite 

telecommunications provider in the Iberian Peninsula), and our company operates the Amazonas 2 and Amazonas 3 satellites, which 
were manufactured by Astrium (EADS Space Company). In December 2002, we entered into an agreement with Hispasat that granted 
and transferred to Hispamar the rights to exploit geostationary orbital position 61 degrees west, and we acquired a minority equity stake 
in Hispamar. 

In 2009, the Amazonas 2 satellite was launched and this satellite commenced commercial operations in early 2010. The Amazonas 

2 satellite was manufactured by Astrium and launched into geostationary orbit of 61 degrees West. This satellite provides both C and 
Ku band transponders and on-board switching, with an expected useful life of 15 years. The Amazonas 2 satellite is owned by a 
subsidiary of Hispasat and Hispamar has been granted the right to operate and lease all of the transponder’s space segment on this 
satellite.

manufactured by Space Systems/Loral and launched into geostationary orbit of 61 degrees West. This satellite provides both C and Ku 
band transponders, with an expected useful life of 15 years. The Amazonas 3 satellite is owned by Hispamar, a subsidiary of Hispasat, 
which operates and leases the transponder’s entire space segment on this satellite. 

As of December 31, 2017, we leased transponders from: 

•

•

Hispamar with 754 MHz of capacity, in C band, on the Amazonas 3 satellite and 432 MHz of capacity in C band on the 
Amazonas 2 satellite to provide voice and data services through 653 remote switches covering 390 municipalities; and 

Hispamar with 98.3 MHz of capacity, in Ku band, on the Amazonas 3 satellite and 540 MHz of capacity in Ku band on the 
Amazonas 2 satellite to provide voice and data services to approximately 3,028 localities. 

DTH Network 

We historically provide our DTH services through a satellite uplink located in Lurin, Peru which receives, encodes and transmits 

the television signals to satellite transponders. We lease these facilities and license the related technology from a subsidiary of 
Telefónica S.A. We lease transponders for the delivery of these television signals to our subscribers from Telefónica S.A. We have 
leased 216 MHz of capacity in Ku band on the Amazonas 3 satellite and 36 MHz of capacity in Ku band on the Amazonas 2 satellite to 
provide DTH services. 

In December 2013, we started providing DTH services through our own head-end located in Rio de Janeiro, Alvorada – Barra da 

Tijuca, which receives, encodes and transmits television signals for satellite transponders. We lease transponders for the delivery of 
these television signals to our subscribers from SES New Skies. We have leased 1.5 GHz of capacity in Ku band, on the SES-6 satellite 
to provide DTH services throughout Brazil. 

Our customers lease satellite dishes and set-top boxes from us as part of their subscriptions to our Oi TV services. 

IP TV Network 

Through our FTTH network, we offer IP TV services in the cities of Rio de Janeiro, Vilar dos Teles, Duque de Caxias and Niteroi, 

in the State of Rio de Janeiro, and the city of Belo Horizonte, in the State of Minas Gerais. For subscribers of our Oi TV services, 
through our DTH or FTTH networks, we also offer OTT services, which provide customers with access to different content on different 
devices (mobile phones, tablets and computers).

Infrastructure Sharing Agreements 

2G and 3G Networks 

In April 2014, we and TIM entered into a memorandum of understanding under which we agreed to the joint construction, 

implementation and reciprocal assignment of elements of our respective 2G and 3G network infrastructure. 

4G Network 

We currently are party to two Radio Access Network, or RAN, sharing agreements with other operators. RAN sharing enables 

operators to share the same physical network, each using its own frequency spectrum resources, thus reducing the deployment costs in 
proportion to each operator’s respective coverage requirements while maintaining all of the characteristics of an individual network 
with respect to our customers. RAN sharing makes use of 3GPP standard features, permitting full technical support. As a result, RAN 
sharing agreements allow us to reduce operating expenses and capital expenditures. 

In November 2012, we entered into a memorandum of understanding with TIM under which we agreed to the joint use of 
elements of our 4G network under a RAN sharing model pursuant to which we have invested in (and provided TIM with access to) 
infrastructure in certain cities, while TIM has invested in (and provided us with access to) infrastructure in other cities. In late 2013, we 
and TIM extended this memorandum of understanding to additional cities and revised certain obligations of each party under the 
memorandum of understanding, which we refer to as the 2013 RAN Sharing Agreement. The 2013 RAN Sharing Agreement has a term 
of 15 years. Under the 2013 RAN Sharing Agreement, we offer 4G technology to over 80% of urban areas in all Brazilian capital cities 
and cities with over 500,000 inhabitants. In 2015, we expanded the 2013 RAN Sharing Arrangement with TIM to cities with over 
200,000 inhabitants, approximately 133 municipalities covered by 4G technology, and we began a RAN sharing arrangement with 
Telefônica Brasil in five municipalities. In 2016, we expanded to cities with over 100,000 inhabitants, reaching 284 cities with 4G 
coverage. In 2017, we expanded to cities with less than 100,000 inhabitants, reaching 813 cities with 4G coverage. 

In June 2015, we entered into a memorandum of understanding under which we agreed to the joint use of elements of the 4G 
network under a RAN sharing model pursuant to which Oi, TIM, and Telefônica Brasil agreed to invest proportionally (50% Telefônica 
Brasil, 25% Oi and 25% TIM) in sites in certain cities based on each operators’ respective coverage obligations, which we refer to as 
the 2015 RAN Sharing Agreement. The 2015 RAN Sharing Agreement has a term of 12 years. In early 2016, ANATEL required the 
inclusion of additional clauses in the agreement allowing an additional operator to be added. This agreement covers 32 cities in 2015, 
150 cities in 2016 and 525 cities in 2017.

maintenance in connection with our external plants and associated equipment, public telephones, and fiber optic and data 
communication networks (including broadband access services) in certain parts of the State of Rio de Janeiro. Over the years, we have 
amended this agreement to expand its scope to the entirety of the State of Rio de Janeiro (following our acquisition of Telemont’s 
operations in Rio de Janeiro), as well as the States of São Paulo, Rio Grande do Sul, Santa Catarina and Paraná (following our 
acquisition of A.R.M Engenharia in June 2016). The total estimated payments under this contract, which expires in January 2022, are 
approximately R$10.0 billion. 

In June 2016, we acquired 100% of the capital stock of A.R.M. Engenharia and changed its corporate name to Rede Conecta – 

Serviços de Rede S.A. In July 2016, we entered into a services agreement with Rede Conecta for installation, operation and corrective 
and preventive maintenance in connection with our external plant and associated equipment, public telephones, and fiber optic and data 
communication networks (including broadband access services) in the States of Maranhão, Piauí, Ceará, Rio Grande do Norte, Paraíba, 
Pernambuco, Alagoas, Sergipe, Bahia, Amazonas, Roraima, Pará and Amapá. The total estimated payments under this contract, which 
expires in June 2021, are approximately R$3.2 billion. 

Outsourced Network Maintenance 

In October 2012, we entered into five-year services agreements with Telemont for installation, operation, and corrective and

The Brazilian telecommunications industry is highly competitive. The competitive environment is significantly affected by key 
trends, including technological and service convergence, market consolidation and combined service offerings by service providers. See 
“Item 5. Operating and Financial Review and Prospects—Principal Factors Affecting Our Financial Condition and Results of 
Operations—Effects of Competition on the Rates that We Realize and the Discounts We Record.” 

Residential Services 

We are the leading provider of residential services in Regions I and II of Brazil with 12.9 million fixed lines in service (including 

the number fixed lines provided to our B2B Services customers) as of December 31, 2017. Based on information available from 
ANATEL, as of December 31, 2017, we had a market share of 54.1% of the total fixed lines in service in Region I (including the 
number fixed lines provided to our B2B Services customers) and a market share of 50.1% of the total fixed lines in service in Region II 
(including the number fixed lines provided to our B2B Services customers). Our principal competitors for fixed-line services are 
(1) Claro, which had a market share of 24.9% of the total fixed lines in service in Region I and a market share of 19.2% of the total 
fixed lines in service in Region II as of December 31, 2017, based on information available from ANATEL, and (2) Telefônica Brasil, 
which had a market share of 13.7% of the total fixed lines in service in Region I and a market share of 25.7% of the total fixed lines in 
service in Region II as of December 31, 2017, based on information available from ANATEL. 

We face competition from other telecommunications services providers, particularly from mobile telecommunications services 

providers, which has led to traffic migration from fixed-line traffic to mobile traffic and the substitution of mobile services in place of 
fixed-line services, encouraged by the prevalence of all-net packages and offers of aggressively-priced packages from some mobile 
telecommunications service providers. The decrease in interconnection rates has discouraged the construction of new fixed-line 
networks. In addition, the decrease in interconnection rates has led to decreases in market prices for telecommunications services by 
enabling telecommunications service providers that use the local fixed-line networks of incumbent fixed-line providers, such as our 
company, to offer lower prices to their customers. We and other companies have combatted this trend by offering subscriptions with 
unlimited calling privileges at the same or similar prices to mitigate the pricing pressure. Finally, our competitors have begun 
competing in the consumer market with bundles or services targeted to the needs of lower income customers. 

Mobile 

We expect to continue to face competition from mobile services providers, which represent the main source of competition in our 

Residential Services business. The number of mobile subscribers in Brazil increased from 121.0 million as of December 31, 2007 to 
236.5 million as of December 31, 2017, based on information available from ANATEL. In addition, due to the proliferation of all-net 
service plans, particularly for mobile services, which offer unlimited long-distance calls and data combination plans, we believe that we 
may be vulnerable to traffic migration as customers with both fixed-line and mobile telephones use their mobile devices to make calls to 
other mobile subscribers. 

Fixed Line 

Claro, a subsidiary of América Móvil, provides local fixed-line services to residential customers through its cable network in the 
portions of Regions I and II where it provides cable television and broadband services under the “Net” brand. As a result, Claro is able 
to offer cable television, broadband and telephone services as a bundle at a very competitive price. We also expect competition from 
Claro to increase in certain cities in our service areas where the volume of demand is attractive. 

We also compete in the State of São Paulo with Telefônica Brasil, which is the incumbent fixed-line service provider in the State 

of São Paulo. Telefônica Brasil has been increasing its competitive activities in Regions I and II, expanding its fiber optic network in 
high-income residential areas and increasing its services to low- and medium-size businesses. We expect competition from Telefônica 
Brasil to increase in certain cities in our service areas where the volume of demand is attractive.

Competition from long-distance fixed-line service providers has decreased as a result of recent reductions in interconnections 
tariffs. The proliferation of all-net plans by fixed-line and mobile services providers that include free minutes for calls to subscribers of 
any operator have and may continue to adversely impact our revenues from fixed-line long-distance calls if our fixed-line customers 
choose to migrate to mobile services for long-distance communications and/or cancel their fixed-line services. Moreover, new 
technologies that serve as alternatives to traditional long-distance telephone calls, such as VoIP and instant internet messaging, have 
captured part of Brazil’s long-distance traffic. 

Broadband 

Cable television providers that offer broadband services, particularly Claro and Telefônica Brasil, represent our principal 
competition in the broadband market. As of December 31, 2017, Claro and Telefônica Brasil had market shares of 24.4% and 16.7%, 
respectively, for broadband services in Regions I and II of Brazil, while we had a market share of 33.4% for broadband services in 
Regions I and II of Brazil, according to data from ANATEL. Both Claro and Telefônica Brasil offer broadband services at higher 
speeds than our offerings, and they offer integrated packages, consisting of subscription television, broadband and voice telephone 
services to cable television subscribers who, in general, have more purchasing power than other consumers. Claro and Telefônica Brasil 
offer strong competition for fixed broadband services in municipalities that have the highest concentration of purchasing power. 

In addition, we compete in our service areas with smaller companies that have been authorized by ANATEL to provide fixed-line 

services, such as voice and broadband. Although regional broadband service providers do not have the same national footprint as 
national operators, they have established networks in the regions in which they operate and often have a market share of approximately 
15% of broadband customers. 

Pay-TV 

In Brazil, the high quality programming of television broadcasters has limited the perceived value of subscription television. As a 

result, the subscription television market in Brazil has a low penetration compared to developed countries and even to other South 
American countries such as Argentina, Chile and Mexico. Penetration rates by subscription television have grown from approximately 
8.6% of Brazilian households in 2006 to approximately 33.7% in 2016. According to information available from ANATEL, the 
Brazilian subscription television market decreased by 4.2% to 8.0 million subscribers as of December 31, 2017 from 18.8 million 
subscribers as of December 31, 2016. 

The primary providers of subscription television services in the regions in which we provide Residential Services are SKY, which 

provides DTH services, and Claro, which provides DTH service under the “Claro TV” brand and Pay-TV services using coaxial cable 
under the “Net” brand. We offer DTH subscription television services throughout the regions in which we provide Residential Services. 

We also deliver Oi TV through our FTTH network in the cities of Rio de Janeiro, Vilar dos Teles, Duque de Caxias and Niteroi, in 

the State of Rio de Janeiro, and the city of Belo Horizonte, in the State of Minas Gerais.

Personal Mobility Services 

The mobile telecommunications services market in Brazil is characterized by intense competition among providers of mobile 

telecommunications services. We compete primarily with Telefônica Brasil, which markets its mobile services under the brand name 
“Vivo,” TIM and Claro, each of which provides services throughout Brazil. 

As of December 31, 2017, based on information available from ANATEL (which includes B2B Services subscribers), we had a 
market share of 16.5% of the total number of mobile subscribers in Brazil, ranking behind Telefônica Brasil with 31.7%, Claro with 
25.0% and TIM with 24.8%. As of December 31, 2017, based on information available from ANATEL, the competitive landscape for 
mobile services was as follows: in Region I, we had a market share of 22.4% of the total number of mobile subscribers, behind 
Telefônica Brasil with 28.9%, TIM with 23.9% and Claro with 22.7%; in Region II, we had a market share of 12.2% of the total number 
of mobile subscribers, ranking behind Telefônica Brasil with 32.5%, Claro with 28.3% and TIM with 26.7%; and in Region III, we had 
a market share of 9.7% of the total number of mobile subscribers, ranking behind Telefônica Brasil with 36.0%, Claro with 25.9% and 
TIM with 24.6%. 

Competition in Mobile Voice and Data Communications Services 

Competitive efforts in the pre-paid and post-paid personal mobility services market generally take the form of traffic subsidies and 

aggressive discounts on data packages. We no longer offer handset subsidies (with the exception of the Oi Pontos program, which 
provides credit to existing post-paid customers to be used on the purchase of a new mobile device), but we do compete on the basis of 
traffic subsidies, all-net plans that eliminate the community effect of traditional telecommunications services in Brazil and discounts on 
data packages. The aggressiveness of promotions is generally driven by the desire of the operator offering the promotion to increase 
market share; however, these promotions generally are for a short duration as the pricing terms offered are not sustainable over the long 
term. 

Studies of telecommunications consumption habits in Brazil show that, given budget restrictions caused by the macroeconomic 

situation, users have shifted away from owning a SIM card from each of the operators (in response to traditional on-net plans that offer 
substantial discounts for calls to the same operator) and have begun to consolidate telecommunications services on a the SIM card that 
offers the best data package. This trend will result in a decline in the overall customer base for pre-paid services, which will require 
operators to offer increasingly comprehensive data packages at aggressive discounts in order to maintain and potentially increase their 
customer bases. 

Our launches of the Oi Mais, Oi Mais Controle and Oi Livre portfolios have kept us on the forefront of competition in the mobile 

services market. We believe our innovative flat rate pricing, all-net model for voice services and text messaging, and robust data 
packages at competitive rates enable us to satisfy the growing customer demand for simpler product offerings and greater access to data. 

In addition, we believe that in the medium-term, personal mobility service providers in Brazil will experience increasing 
competition from OTT providers, as customers shift from mobile voice and SMS communications to internet-based voice and data 
communications through computers and smartphone or tablet applications such as WhatsApp, Viber and Skype. Since November 2011, 
we have deployed a network of Wi-Fi hotspots, which is composed of sub networks that are accessible from (1) indoor public and 
commercial sites, such as coffee shops, airports and shopping centers, (2) outdoor public spaces and (3) residential access points of our 
fixed-line customers that share access points in association with Fon. As of December 31, 2017, our Wi-Fi network consisted of more 
than two million hotspots, with broadband access compatible with more than two million access points provided by Fon, which allows 
our customers to access Fon lines worldwide. Our data customers (both mobile and fixed) have unlimited access to our Wi-Fi hotspots, 
extending our mobile coverage and improving customer experience. 

Competition in Mobile Data Only Services 

Studies of telecommunications consumption habits in Brazil show that users are demanding more data for use in social networking 
sites and smartphone applications such as WhatsApp. This shift from voice to data consumption affects our Personal Mobility Services 
business in two ways: (1) it enables customers to use data to communicate with anyone anywhere in the world via internet instant 
messaging systems available on smartphone applications such as WhatsApp, and (2) it enables consumers to use data to call anyone 
anywhere in the world using the VoIP capabilities available in such smartphone applications.

In the post-paid mobile data communications market, our primary competitors are Telefônica Brasil, Claro and TIM. As of 
December 31, 2017, based on information available from ANATEL, which includes B2B Services subscribers, we had a market share 
of 10.4% of the total number of post-paid mobile data subscribers in Brazil (including hybrid data plan subscribers), ranking behind 
Telefônica Brasil with 41.8%, Claro with 23.1% and TIM with 20.2%. We believe that our most direct competitor in this market is 
TIM, whose customer acquisition and retention strategy of offering traffic subsidies, all-net plans and aggressive discounts on data 
packages most closely resembles ours. On the other hand, Telefônica Brasil and Claro, whose prices are typically higher than those of 
the other mobile data service providers in the market, primarily focus on the high-end consumer market. 

In the pre-paid mobile data communications market, our primary competitors are also Telefônica Brasil, Claro and TIM. As of 

December 31, 2017, based on information available from ANATEL, which includes B2B Services subscribers, we had a market share 
of 20.1% of the total number of pre-paid mobile data subscribers in Brazil, ranking behind TIM with 27.5%, Claro with 26.0% and 
Telefônica Brasil with 25.7%. As in the post-paid mobile data communications market, we believe that our most direct competitor in 
the pre-paid mobile data communications market is TIM, who offers plans similar to Oi Livre. 

Competition in Mobile Long-Distance Services 

Recent reductions in the interconnection rates for Regions I, II and III have resulted in lower costs for long-distance services, both 

to us and to our customers. As a result, all of the major mobile services providers now offer unlimited voice and messaging plans that 
allow customers to call anywhere in Brazil for a flat rate. We believe that the introduction of unlimited plans, coupled with more robust 
data packages that allow consumers to use smartphones applications more freely, have substantially reduced competition in the mobile 
long-distance services market. 

B2B Services 

The competition risks relating to the fixed-line and mobile services we provide to our SME customers are similar to those relating 

to the fixed-line and mobile services we provide to our residential and personal mobility customers. The competition risks relating to 
the fixed-line and mobile services we provide to our corporate customers are also similar. 

In recent years, there has been a shift among corporate and SME services providers toward value-added services. With the 
exception of the Oi Mais Empresas app and web service, our value-added products and services for the SME segment are substantially 
similar to those offered by our competitors, and we rely on client service and customer satisfaction to maintain existing customers and 
attract new customers. Our principal competitors for both core and value-added services for SME and corporate customers are Claro, 
Telefônica Brasil and TIM, as well as smaller niche companies. 

The Brazilian recession has had a significant negative effect on our operating revenue and margins as SMEs generally, including 

our customers, have reduced the size of their businesses and in some cases ceased operations. In addition, a number of our corporate 
customers have reduced their telecommunications spending as part of their overall cost-cutting efforts. 

Concessions, Authorizations and Licenses 

Under the General Telecommunications Law (Lei Geral das Telecomunicações) and ANATEL regulations, the right to provide 

telecommunications services is granted either through a concession under the public regime or an authorization under the private 
regime. For additional details regarding the rights and obligations of service providers operating under the public regime and the private 
regime, see “—Telecommunication Regulations—Regulation of the Brazilian Telecommunications Industry— Concessions and 
Authorizations.” We operate under: 

•

•

•

a concession to provide local fixed-line services in Region I (other than the 57 municipalities in the State of Minas Gerais 
that are excluded from the concession area of Region I) and a concession to provide local fixed-line services in Region II 
(other than the nine municipalities in the States of Goiás, Mato Grosso do Sul and Paraná that are excluded from the 
concession area of Region II); 

a concession to provide domestic long-distance services in Region I (other than the 57 municipalities in the State of Minas 
Gerais that are excluded from the concession area of Region I) and a concession to provide domestic long-distance services 
in Region II (other than the nine municipalities in the States of Goiás, Mato Grosso do Sul and Paraná that are excluded from 
the concession area of Region II); 

authorizations to provide personal mobile services in Regions I, II and III;

authorizations to provide local fixed-line services and domestic long-distance services in (1) the 57 municipalities in the 
State of Minas Gerais that are excluded from the concession area of Region I, (2) the nine municipalities in the States of 
Goiás, Mato Grosso do Sul and Paraná that are excluded from the concession area of Region II, and (3) Region III; 

authorizations to provide international long-distance services originating anywhere in Brazil; 

authorizations to provide Multimedia Communication Services (Serviço de Comunicação Multimídia) throughout Brazil; and 

an authorization to provide subscription television services throughout Brazil. 

These concessions and authorizations allow us to provide specific services in designated geographic areas and set forth certain 

obligations with which we must comply. 

Fixed-Line and Domestic Long-Distance Services Concession Agreements 

We have entered into concession agreements with ANATEL that govern our concessions to provide (1) fixed-line services in the 
Federal District and each of the states of Regions I and II and (2) domestic long-distance services originating from the Federal District 
and each of the states of Regions I and II. Each of our fixed-line and domestic long-distance concession agreements: 

•

•

•

•

•

•

expires on December 31, 2025; 

sets forth the parameters that govern adjustments to our rates for fixed-line services; 

requires us to comply with the network expansion obligations set forth in the General Plan on Universal Service Goals; 

requires us to implement electronic billing systems; 

sets forth the conditions under which ANATEL may access information from us; and 

requires us to pay fines for systemic service interruptions. 

In addition to the above, each of our concession agreements for fixed-line services requires us to comply with certain quality of 

service obligations set forth in these concession agreements as well as the quality of service obligations set forth in the General Plan on 
Quality Goals. 

Each of our fixed line concessions requires payment of biannual fees equal to 2.0% of our net operating revenue that is derived 

from the provision of local fixed-line services (excluding taxes and social contributions) during the immediately preceding year. 
Similarly, each of our domestic long-distance concessions requires payment of biannual fees equal to 2.0% of our net operating revenue 
that is derived from the provision of domestic long-distance services (excluding taxes and social contributions) during the immediately 
preceding year. 

The General Plan on Universal Service Goals also require us to provide transmission lines connecting our fiber-optic internet 
backbones to municipalities in our concession areas in which we did not provide internet service, which we refer to as backhaul. Under 
these concession agreements, we are obligated to set up backhaul in 3,252 municipalities in Regions I and II. The facilities that we 
constructed to meet these obligations are considered to be property that is part of our concessions and will therefore revert to the 
Brazilian government on January 1, 2026. 

These concession agreements provide that ANATEL may modify their terms in 2015 and 2020 and may revoke them prior to 

expiration under the circumstances described under “—Telecommunications Regulation—Regulation of the Brazilian 
Telecommunications Industry—Regulation of Fixed-Line Services—Termination of a Concession.” The modification right permits 
ANATEL to impose new terms and conditions in response to changes in technology, competition in the marketplace and domestic and 
international economic conditions. ANATEL is obligated to engage in public consultation in connection with each of these potential 
modifications.

On June 27, 2014, ANATEL opened a public comment period for the revision of the terms of our concession agreements. The 
comment period, which ended on December 26, 2014, was opened for comments on certain topics such as service universalization, rates 
and fees, among others. Throughout 2015, ANATEL, the Brazilian Ministry of Communications and telecommunications service 
providers met regularly to discuss possible amendments to each of the concession agreements granted by ANATEL, including ours, and 
the implications of the developments and demands in the telecommunications sector in recent years. In September 2015, the Brazilian 
Ministry of Communications created a working group to evaluate the status of the concessions and propose guidelines for the 
amendment of the concession agreements. In April 2016, the Brazilian Ministry of Communications issued a decree addressing 
guidelines for the establishment of a new regulatory framework for telecommunications, which were expected to be implemented by 
ANATEL through the conclusion of the concession amendments. In line with the provisions of PLC 79, these guidelines provided for, 
among other things, the expansion of broadband services (including in rural regions), the elimination of the reversibility of assets, and 
an extension of the terms of concessions, which in our case are currently scheduled to expire in 2025. As a result of the publication of 
these guidelines, ANATEL requested a further postponement of the review of our concession agreements, which was granted. The 
implementation of these guidelines, however, depends on the passage of PLC 79 to provide the necessary legal authority and 
framework. As a result of the Brazilian Congress’s failure to date to pass PLC 79, the review of our concession agreements, which was 
scheduled to occur by June 2017, has not yet taken place, and further discussions regarding amendments to our concession agreements 
have halted pending resolution of PLC 79. Under their existing terms, our concession agreements may be amended by December 2020 
at the latest. If PLC 79 is not passed, our concession agreements will expire in 2025 without the possibility of renewal. 

In connection with the consideration of revisions to the concession agreements under the public regime, in January 2017, 

ANATEL proposed revisions to the terms of the General Plan of Grants (Plano Geral de Outorgas), in line with the provisions of PLC 
79, which include the ability of companies operating under a concession in the public regime to convert their concessions into 
authorizations to operate in the private regime and thereby eliminate a number of substantial obligations currently imposed by the 
concession regime, in exchange for the assumption of obligations to make additional investments in their networks, primarily related to 
the expansion of broadband services or through the payment of fees to ANATEL. The value of the obligations currently imposed by the 
concession agreement and, therefore, the cost of the additional investments or fees to be paid to ANATEL in exchange for the 
elimination of such obligations, would be subject to discussion between the parties, with ANATEL having the ability to make the final 
valuation. However, as a result of the legislative gridlock faced by PLC 79, ANATEL has halted implementation of the General Plan of 
Grants. For more information about PLC 79 and ANATEL’s proposed revisions to the terms of the General Plan of Grants, see 
“—Regulation of the Brazilian Telecommunications Industry—Other Regulatory Matters—New Regulatory Framework.” 

We cannot assure you that any future amendments to our concession agreements or the General Plan of Grants will not impose 

requirements on our company that will require us to undertake significant capital expenditures or will not modify the rate-setting 
procedures applicable to us in a manner that will significantly reduce the net operating revenue that we generate from our Brazilian 
fixed-line businesses. If the amendments to our Brazilian concession agreements have these effects, our business, financial condition 
and results of operations could be materially adversely affected. 

For more information regarding the regulation of our fixed-line services, the General Plan on Universal Service Goals and the 
General Plan on Quality Goals, see “—Regulation of the Brazilian Telecommunications Industry— Regulation of Fixed-Line Services.” 

2G Radio Frequency Licenses 

We hold fifteen licenses to use radio frequency spectrum to provide 2G services in Regions I and II and four in Region III. These 
licenses grant us permission to use the applicable radio spectrum for 15 years from the date of the authorization agreement under which 
they are granted and are renewable for additional 15-year terms. Upon renewal of any of these licenses and on every second anniversary 
of such renewal, we will be required to pay an amount equal to 2.0% of our prior year’s net operating revenue from personal mobile 
services. The initial terms of one of our radio frequency spectrum licenses expired in 2016 and was extended for an additional 15 year 
term. The initial terms of the remainder of our radio frequency spectrum licenses expire between 2022 and 2023.

Our authorization agreements are subject to network scope and service performance obligations set forth in these authorization 
agreements. Under these obligations we are required to service all municipalities in Brazil with a population in excess of 100,000. A 
municipality is considered “serviced” when the covered service area contains at least 80% of the urban area in the municipality. Our 
failure to meet these targets may result in the imposition of penalties established in ANATEL regulations and, in extreme 
circumstances, in termination of our personal mobile services authorizations by ANATEL. As of the date of this annual report, although 
we believe that we are in compliance with the network scope and service performance obligations set forth in these authorization 
agreements, ANATEL has not yet made its final determination with respect to our compliance with certain obligations to provide 
services under the 900 MHz spectrum. We are currently discussing this matter with ANATEL. Furthermore, we have obtained judicial 
protection under the RJ Proceedings to forego renewal of the performance guarantees we would have otherwise been required to 
maintain with respect to the obligations under discussion. 

3G Radio Frequency Licenses 

We hold six licenses to use radio frequency spectrum to provide 3G services in Regions I, II and III. Each of these licenses grants 
us permission to use the applicable radio spectrum for 15 years from the date of grant and is renewable for additional 15-year terms. We 
will be required to pay an amount equal to 2.0% of our prior year’s net operating revenue from personal mobile services upon renewal 
of the license and on every second anniversary of the renewal. The initial terms of these licenses expire in 2023. 

These radio frequency licenses include network scope obligations. Under these obligations, we are currently required to 

(1) provide service to 459 municipalities that did not have mobile services at the time these licenses were granted with either 2G or 3G 
mobile telecommunications services, (2) provide 3G service to all state capitals in Brazil, the Federal District and all municipalities 
covered by these licenses with a population in excess of 100,000 inhabitants, (3) provide 3G service to 50% of all of the municipalities 
with a population between 30,000 and 100,000, and (4) provide 3G service to 60% of the municipalities, including 684 specified 
municipalities, covered by these licenses with a population less than 30,000. 

A municipality is considered “serviced” when the covered service area contains at least 80% of the urban area in the municipality. 

Our failure to meet these targets may result in the imposition of penalties established in ANATEL regulations and, in extreme 
circumstances, in termination of our 3G frequency licenses by ANATEL. As of the date of this annual report, although we believe that 
we are substantially in compliance with the network scope and service performance obligations set forth in these licenses, ANATEL has 
not yet made its final determination with respect to our compliance. We are currently discussing this matter with ANATEL. 
Furthermore, we have obtained judicial protection under the RJ Proceedings to forego renewal of the performance guarantees we would 
have otherwise been required to maintain with respect to the obligations under discussion. 

4G Radio Frequency Licenses 

We hold three licenses to use radio frequencies in 2.5 GHz sub-bands to provide 4G services in Regions I, II and III. Each of these 

licenses grants us permission to use the applicable radio spectrum for 15 years from the date of grant and is renewable for additional 
15-year terms. We will be required to pay an amount equal to 2.0% of our prior year’s net operating revenue from 4G services upon 
renewal of the license and on every second anniversary of the renewal. The initial terms of these licenses expire in 2027. 

These radio frequency licenses include network scope obligations. Under these obligations, we are currently required to provide: 

•

•

•

•

4G service in (1) all state capitals and municipalities with a population of 30,000 or more and (2) 30% of the municipalities 
covered by these licenses with a population less than 30,000 and the Federal District; provided, however, that for the latter, 
we are may comply with this obligation by providing service with transmission rates equal to 1.9/2.1 GHz or above; 

voice services in the 450 MHz or other spectrum granted to us and data services at minimum upload speeds of 256 kbps and 
download speeds of 1Mbps and a minimum monthly allowance of 500 MB in 962 municipalities in the States of Goiás, Mato 
Grosso, Mato Grosso do Sul, Rio Grande do Sul and the Federal District; 

unlimited data services at minimum upload speeds of 256 kbps and download speeds of 1Mbps to rural schools in 962 
municipalities in the States of Goiás, Mato Grosso, Mato Grosso do Sul, Rio Grande do Sul and the Federal District; and 

make our fixed-line network available to other telecommunications service providers to allow them to comply with their 
obligations under the General Plan on Universal Service Goals in 962 municipalities in the States of Goiás, Mato Grosso, 
Mato Grosso do Sul, Rio Grande do Sul and the Federal District.

provide 4G service to 60% of the municipalities covered by these licenses with a population less than 30,000 by 
December 31, 2018, provided, however, that for these municipalities, we are may comply with this obligation by providing 
service with transmission rates equal to 1.9/2.1 GHz or above; and 

provide 4G service to all of the municipalities covered by these licenses with a population less than 30,000 by December 31, 
2019. 

In addition, our 4G radio frequency licenses impose minimum investment obligations in domestic technologies. At least 65% of 

the cost of all goods, services, equipment, telecommunications systems and data networks that we purchase to meet our 4G service 
obligations must developed in Brazil. This minimum requirement will increase to 70% by December 31, 2022. 

Our failure to meet these targets may result in the imposition of penalties established in ANATEL regulations and, in extreme 
circumstances, in termination of our 4G frequency licenses by ANATEL. As of the date of this annual report, although we believe that 
we are in compliance with the network scope and service performance obligations set forth in these licenses, ANATEL is currently 
debating our compliance with certain obligations to provide services under the 450 MHz spectrum. Since we do not yet have all of the 
necessary technology to support the use of the 450 MHz spectrum using land frequencies, we have been meeting our coverage 
obligations in certain areas using satellites. If ANATEL decides that we have not been meeting our obligations, we will be given two 
years to comply, failure of which may lead to termination of our authorizations to use 450 MHz frequencies. Furthermore, we have 
obtained judicial protection under the RJ Proceedings to forego renewal of the performance guarantees we would have otherwise been 
required to maintain with respect to the obligations under discussion. 

Fixed-Line Services Authorization Agreements 

We have entered into authorization agreements with ANATEL that govern our authorizations to provide local fixed-line services 

in and domestic long-distance services originating from (1) the 57 municipalities in the State of Minas Gerais that are excluded from the 
concession area of Region I, (2) the nine municipalities in the States of Goiás, Mato Grosso do Sul and Paraná that are excluded from 
the concession area of Region II, and (3) Region III. These authorizations do not have termination dates and require us to comply with 
certain quality of service obligations set forth in the General Plan on Quality Goals. 

We have also entered into authorization agreements with ANATEL that govern our authorizations to provide international long-
distance services originating from anywhere in Brazil. These authorizations do not have termination dates and require us to comply with 
quality of service obligations set forth in the General Plan on Quality Goals. 

Multimedia Communication Services Authorization Agreements 

We have Multimedia Communication Services authorizations, which superseded our prior Telecommunications Network 

Transportation Services (Serviço de Rede de Transporte de Telecomunicações) authorizations, permitting us to provide high speed data 
service. 

The Multimedia Communication Services authorizations became effective in May 2003 and cover the same geographical areas as 

our concession agreements. In April 2008, in connection with the amendments to our fixed-line services concessions, we agreed to 
provide internet service free of charge until December 31, 2025 to all urban schools in the areas of our concession agreements.

Term of Commitment to Adhere to National Broadband Plan 

On June 30, 2011, we entered into a Term of Commitment (Termo de Compromisso) with ANATEL and the Brazilian Ministry of 

Communications to formalize our voluntary commitment to adhere to the terms of the National Broadband Plan, created in May 2010 
by Executive Decree No. 7,175/10 with the goal of making broadband access available at low cost, regardless of technology, throughout 
Brazil. Pursuant to the Term of Commitment, we are required to offer (1) broadband services with minimum upload and download 
capabilities to retail customers in certain sectors of Regions I and II for a maximum price of R$35 per month (or R$29.90 in ICMS-
exempt states), plus fees, and (2) access to our broadband infrastructure to certain wholesale customers, including small businesses and 
municipalities, in certain sectors of Regions I and II for a maximum price of R$1,253 per 2 Mbps per month and a one-time installation 
fee, while observing all quality standards under ANATEL regulations. Both retail and wholesale services are subject to certain network 
capacity limits and need only be provided at the demand of the customer. Pursuant to the Term of Commitment, we have offered the 
required services to all eligible retail and wholesale customers since the date of its execution and have gradually increased the capacities 
offered to wholesale customers since November 2011. We have been obligated to provide the maximum capacities established by the 
Term of Commitment to eligible wholesale customers since June 30, 2015. In addition, the Term of Commitment requires that we: 

•

•

•

provide one public internet access point for the first 20,000 inhabitants and one additional access point for each subsequent 
10,000 inhabitants, with a limit of six access points, at a speed of 2 Mbps, in each municipality that has only satellite service, 
free of charge and upon demand of such municipality; 

adequately advertise the services contemplated by the Term of Commitment and present to the Brazilian Ministry of 
Communications semi-annual reports detailing our marketing efforts; and 

make our best efforts to offer broadband services to retail customers at speeds of up to 5 Mbps, reaching the largest possible 
number of municipalities. 

The Term of Commitment expired on December 31, 2016 and has not been renewed. Although we believe that we are in 

compliance with all of our network scope and service performance obligations set forth under the Term of Commitment, as of the date 
of this annual report, ANATEL has yet to complete its review, and we cannot predict when it will do so. Our failure to meet our 
obligations may result in the imposition of penalties established in ANATEL regulations. 

Subscription Television Authorization Agreement 

In November 2008, we entered into a 15-year authorization agreement with ANATEL that governs our use of satellite technology 
to provide DTH satellite television services throughout Brazil. Under this authorization, we are required to furnish equipment to certain 
public institutions, to make channels available for broadcasting by specified public institutions, and to comply with quality of service 
obligations set forth in applicable ANATEL regulations. 

In December 2012, ANATEL granted our request to convert our DTH authorization agreement into a Conditional Access Service 

authorization allowing us to provide nationwide subscription television services through any technology, including satellite, wireline, 
optical fiber and coaxial cable. The Conditional Access Service authorization agreement authorized us to offer the services to be 
governed by such agreement, including IP TV. In accordance with Law No. 12,485/11, which approved the Conditional Access Service 
regime, our Conditional Access Service authorization prohibits us from creating television content or owning more than 30% of a 
company that creates content. We are also required to carry a certain percentage of Brazilian programming, including open channels 
and public access channels. 

Research and Development 

We conduct independent innovation, research and development in areas of telecommunications services but historically we have 

not independently developed new telecommunications technologies. We depend primarily on suppliers of telecommunications 
equipment for the development of new technology. 

As a condition to ANATEL’s approval of Telemar’s acquisition of control of our company in January 2009, Telemar agreed to 

make annual investments in innovation, research and development through 2018 in amounts equal to at least 50% of the amounts of its 
contributions to the Fund for the Technological Development of Telecommunications (Fundo para o Desenvolvimento Tecnológico das 
Telecomunicações), or FUNTTEL. To fulfill this obligation, as well as to centralize our innovation, research and development activities 
and programs, in 2009, we created a division to manage innovation, research and development with the mission of coordinating and 
promoting efforts and projects that it develops.

Our technology laboratory performs a variety of functions, such as operation support systems, business support systems and 
information security. We conduct trials of technologies from different vendors in this laboratory to evaluate these technologies for 
deployment. 

Since 2009, we have executed cooperation agreements with the following national research centers: Technological Projects, 

Research and Studies Coordination Foundation (Fundação Coordenação de Projetos, Pesquisas e Estudos Tecnológicos – 
COPPETEC), Telecommunications Research and Development Foundation (Fundação Centro de Pesquisa e Desenvolvimento em 
Telecomunicações—CPqD), and PUC-RJ. We have also executed cooperation agreements with Brazilian national telecommunications 
suppliers which develop technology in Brazil, such as Nokia AsGa S.A., Digitel S.A. – Indústria Eletrônica and Padtec S.A. Since 
2009, we have signed more than 10 such cooperation agreements. 

In order to achieve our goals on innovation investments in the last three years, we intensified the process for the exploration of 

innovative services and activities concerning innovation, research, development and to promote an open innovation ecosystem through 
our inhouse incubator, “Incubadora OiTo” our inhouse development and innovation incubator in Rio de Janeiro. “Incubadora OiTo” is 
a development and innovation hub responsible for generating new business, accelerating technological solutions, developing startups 
and supporting social initiatives. 

Our investments in innovation, research and development totaled R$16 million in 2017, R$20 million in 2016 and R$20 million in 

2015. 

Property, Plant and Equipment 

Our principal Brazilian properties, owned and leased, are located in Regions I and II. As of December 31, 2017 and 2016, the net 

book value of our property, plant and equipment in Brazil was R$27,083 million and R$26,080 million, respectively. Our main 
equipment in Brazil consists of transmission equipment, trunking and switching stations (including local, tandem and transit telephone 
exchanges), metallic and fiber-optic cable networks and lines, underground ducts, posts and towers, data communication equipment, 
network systems and infrastructure (including alternating and direct current supply equipment) and motor-generator groups. 

As of December 31, 2017 and 2016, of the net book value of our property, plant and equipment in Brazil, (1) transmission and 
other equipment represented 49.7% and 51.4%, respectively; (2) infrastructure, primarily underground ducts, post and towers, cables 
and lines represented 22.4% and 22.6%, respectively; (3) work in progress represented 12.7% and 9.3%, respectively; (4) buildings 
represented 6.4% and 6.8%, respectively; (5) automatic switching equipment represented 5.2% and 6.5%, respectively; and (6) other 
fixed assets represented 3.5% and 3.4%, respectively. 

All Brazilian property, plant and equipment that are essential in providing the services described in our concession agreements are 

considered “reversible assets,” which means that, should our concession agreements expire or terminate without being renewed, these 
assets will automatically revert to ANATEL. There are no other encumbrances that may affect the utilization of our property, plant and 
equipment. For more details, see note 13 to our consolidated financial statements included in this annual report. 

Intellectual Property 

We believe the trademarks that identify us and our Brazilian businesses are important for us, and as a result, we have taken steps 

to protect them before the Brazilian Patent and Trademark Office (Instituto Nacional de Propriedade Industrial), or BPTO. As of 
December 31, 2017, we had 887 trademarks registered by the BPTO and 432 pending trademark applications. Our main trademark used 
in Brazil, “Oi,” is registered by the BPTO in several classes, which allows us to use this trademark in a variety of markets in which we 
operate, including in connection with our fixed-line, mobile and broadband services. Among the various registered trademarks, 14 are 
being contested by third parties. In addition, 58 of our pending trademark applications have been challenged by third parties. 

As of December 31, 2017, we had 453 domain names registered by the Center of Information and Coordination of Dot Br –NIC. 
Br, the agency responsible for registering domain names in Brazil. The information included on our websites or that might be accessed 
through our websites is not included in this annual report and is not incorporated into this annual report by reference. 

As of December 31, 2017, the BPTO had granted nine patents, utility models or industrial designs in the name of our company. 
We had also filed six patent applications, which are currently being examined by the BPTO. Requests for technical examination have 
been submitted to the BPTO for all of these pending patent applications. Once the examination is concluded, BPTO will issue an 
official decision accepting or rejecting the application, which will be published in the Official Gazette. If granted, the patent will be 
enforced for 20 years beginning from filing date.

Pursuant to requirements in our Brazilian concession agreements, we maintain the following insurance policies: (1) all risk 

property insurance covering all insurable assets pertaining to the concessions; and (2) loss of profit insurance covering lost profits 
deriving from property damage and business interruption. 

In addition to the above policies, we maintain civil liability insurance in Brazil. Our assets that are of material value and/or 
exposed to high degrees of risks are also insured. All of our insurance coverage was purchased from highly rated insurance companies 
in Brazil. 

We believe that our current insurance coverage is suitable to our Brazilian operations. 

Social Responsibility 

In 2001, we created Instituto Telemar, known as Oi Futuro, Oi’s corporate social responsibility institute, which has been 
designated a Public Interest Organization (Organização da Sociedade Civil de Interesse Público) by the Brazilian Ministry of Justice 
(Ministério da Justiça). Oi Futuro acts as an innovation network, catalyzing the transformation in the fields of education, cultural 
activities, social innovation and sports. Oi Futuro develops and accelerates social impact initiatives through collaborative solutions and 
innovation. We believe that innovation and creativity empower personal and collective development, which should be strengthened 
through technology and dissemination of information. 

In the field of education, Oi Futuro invests in new approaches to learning and teaching to transform the classroom environment 

and preparing young people for future jobs. Created in 2006, the Advanced Education Center (Núcleo Avançado em Educação), or 
NAVE, trains young students for digital and creative economies, focusing on the production of games, applications and audiovisual 
products. This program, developed as a partnership with the Secretaries of Education of the States of Rio de Janeiro and Pernambuco, 
offers integrated and professional high school education for 1,000 students. In addition to obtaining technical training, NAVE students 
are encouraged to develop an entrepreneurial spirit and to establish their first professional connections through projects and events, 
favoring their integration with the innovative market. 

In the field of cultural activities, Oi Futuro also serves as a creative catalyst, motivating people through art and stimulating 
collaborative projects by sponsoring cultural projects from all regions of Brazil. In 2017, Oi Futuro sponsored 68 cultural projects. We 
also operate a cultural center in Rio de Janeiro, with a program that stimulates avant-garde production and convergence of 
contemporary art and technology, and manage the Museum of Telecommunications in Rio de Janeiro. In 2017, we launched LabSonica, 
a sound and music experimentation lab created to stimulate creativity and innovation in the field of sound. With the new laboratory, we 
will offer technical support and physical structures for artistic productions, such as a recording studio, rehearsal rooms, studio, 
auditorium and coworking space. 

In the field of social innovation, Oi Futuro launched Labora, a social impact lab that supports social entrepreneurs who put 
forward new ideas, actions and prototypes for addressing contemporary challenges. We promote social initiatives that aim to create a 
more abundant future through connections between changemakers, entrepreneurs, investors and organizations and mentoring. In 2017, 
Oi Futuro supported 25 social innovation projects. 

In the field of sports, Oi Futuro invests in projects that promote social inclusion and citizenship. 

In 2017 and 2016, we contributed R$22 million and R$23 million, respectively, to these projects and programs. 

Operations in Africa 

In 2006, PT Ventures formed Africatel Holdings B.V., or Africatel, and subsequently (1) contributed to Africatel its equity 
interests in (a) Unitel, which operates in Angola, and (b) Cabo Verde Telecom, S.A., or CVTelecom, which operates in Cape Verde, 
among others, and (2) acquired (a) 34% of the equity interest in Mobile Telecommunications Limited, or MTC, which operates in 
Namibia, and (b) 51% of the equity interest in CST – Companhia Santomense de Telecomunicações S.A.R.L., or CST, which operates 
in São Tomé and Príncipe. In 2007, PT Ventures sold 22% of the equity interests in Africatel to Samba Luxco, an affiliate of Helios 
Investors L.P., a private equity firm operating in sub-Saharan Africa, and entered into a shareholders’ agreement with Samba Luxco 
regarding governance and liquidity rights relating to Africatel. In 2008, PT Ventures transferred its equity interests in Africatel to 
Pharol, which sold an additional 3% of the equity interests in Africatel to Samba Luxco. In 2009, Pharol sold 100% of the equity 
interests in PT Ventures to Africatel.

As of December 31, 2017, in addition to its interests in Unitel, MTC, CVTelecom and CST, Africatel owned Directel—Listas 
Telefónicas Internacionais, Lda., or Directel, which publishes telephone directories and operates related data bases in Angola, Cabo 
Verde, Mozambique, Uganda and Kenya. 

As a result of our acquisition of PT Portugal in May 2014 and PT Portugal’s transfer of all of the outstanding share capital of PT 
Participações, which holds our direct and indirect interests in Africatel and TPT, to Oi in connection with our sale of PT Portugal, we 
owned 75% of the equity interests in Africatel. 

Pharol, our subsidiaries PT Ventures and Africatel GmbH & Co KG, or Africatel GmbH, and Samba Luxco are parties to a 
shareholders’ agreement under which we have ownership and management control of Africatel, which we refer to as the Africatel 
shareholders’ agreement. In September 2014, Samba Luxco claimed that Oi’s acquisition of PT Portugal was deemed a change of 
control of Pharol under the Africatel shareholders’ agreement, and that this change of control entitled Samba Luxco to exercise a put 
right under the Africatel shareholders’ agreement at the fair market equity value of Samba Luxco’s Africatel shares. In November 2014, 
Samba Luxco commenced arbitral proceedings against our subsidiary, Africatel GmbH, which directly holds our interest in Africatel, in 
the International Court of Arbitration of the International Chamber of Commerce. 

In June 2016, we and Samba Luxco entered into a settlement agreement under which (1) Samba Luxco agreed to waive certain 

approval rights under the Africatel shareholders’ agreement, and (2) Samba Luxco agreed to transfer to Africatel 11% of the share 
capital of Africatel in exchange for Africatel’s transfer to Samba Luxco of Africatel’s interest in MTC. These transfers were completed 
on January 31, 2017, as a result of which Samba Luxco’s equity interest in Africatel was reduced from 25% to 14%. As a consequence, 
on February 2, 2017, the parties to these proceedings informed the arbitral tribunal of the full and final settlement of their dispute. 
Samba Luxco has withdrawn all claims brought in the arbitration and released Oi’s subsidiaries from all past and present claims relating 
to alleged breaches of the Africatel shareholders’ agreement. 

Unitel, Angola 

In 2000, PT Ventures, then a wholly-owned subsidiary of Pharol, acquired 25% of the share capital of Unitel, a 2G mobile 
operator in Angola. Unitel began operations in Luanda in 2001. In connection with this investment, PT Ventures entered into a 
shareholders’ agreement with the other shareholders of Unitel regarding governance and liquidity rights relating to Unitel, and dispute 
resolution provisions. In 2007, Pharol contributed its shares of PT Ventures to Africatel. As a result of our acquisition of PT Portugal in 
May 2014 and PT Portugal’s transfer of all of the outstanding share capital of PT Participações to Oi in connection with our sale of PT 
Portugal, we had an 18.75% economic interest in Unitel. As a result of Samba Luxco’s transfer to Africatel 11% of the share capital of 
Africatel in January 2017, we have a 21.50% economic interest in Unitel. We account for this investment as an asset held-for-sale. We 
have brought suits against Unitel in the courts of Angola and have instituted arbitral proceedings against the other shareholders of 
Unitel in the International Court of Arbitration of the International Chamber of Commerce based on our inability to collect dividends 
owed to us by Unitel and breaches of the Unitel shareholders’ agreement. For more information about these proceedings, see “Item 3. 
Key Information—Risk Factors—Risks Relating to Our African and Asian Operations “ and “Item 8. Financial Information—Legal 
Proceedings—Legal Proceedings Relating to Our Interest in Unitel.” 

CVTelecom, Cape Verde 

PT Ventures owns 40% of the share capital of CVTelecom, a provider of fixed-line and mobile services in the Cabo Verde Islands. 

In 2000, PT Ventures entered into a shareholders’ agreement with the other shareholders of CVTelecom, regarding governance and 
liquidity rights relating to CVTelecom, which allowed PT Ventures to set and control the financial and operating policies of 
CVTelecom. As a result of our acquisition of PT Portugal, we fully consolidated CVTelecom in our financial statements as of 
December 31, 2014. 

In November 2014, the Government of Cape Verde, which is a shareholder of CVTelecom, notified us that as a result of our 
acquisition of PT Portugal, the shareholders’ agreement governing CVTelecom had been terminated. At a general shareholders’ meeting 
of CVTelecom in March 2015, PT Ventures was only able to elect three of the seven members of the board of directors of CVTelecom. 
In March 2015, PT Ventures commenced an arbitration proceeding before the International Chamber of Commerce, or ICC, disputing 
this interpretation of the shareholders’ agreement, and PT Ventures intends to vigorously defend its rights under the shareholders’ 
agreement. Also in March 2015, PT Ventures commenced an arbitration proceeding against the Republic of Cabo Verde before the 
International Centre for Settlement of Investment Disputes, or ICSID, due to the violation of CVTelecom’s exclusivity rights under the 
concession agreement by the Republic of Cabo Verde. Both proceedings had been temporarily suspended so that the parties could 
engage in negotiations to seek an alternative resolution of these disputes but the arbitrations were resumed in February 2017. As a result 
of these disputes, for dates and periods ending after January 1, 2015, we have recorded our interest in CVTelecom under the equity 
method.

As of December 31, 2016, CVTelecom had approximately 52,700 fixed-lines in service. As of December 31, 2016, CVTelecom 

had approximately 368,000 active mobile telephone cards. As of December 31, 2016, CVTelecom had approximately 14,400 broadband 
customers and 5,400 Pay TV customers. 

CVTelecom was established in 1995 and provides fixed-line and mobile telecommunications services under the terms of a 25-year 

license granted in 1996. In December 2011, CVTelecom was granted a license to provide 3G services in Cabo Verde. In May 2012, 
CVTelecom’s connection to the West African Cable System, a submarine cable which connects CVTelecom’s network to networks in 
West Africa and Europe, began operating. 

In 2006, the National Communications Agency (Agência Nacional das Comunicações) granted the second license to provide 

fixed-line and mobile telecommunications services in Cabo Verde to T Plus S.A., or T Plus, which commenced operations under the 
brand “T+” in December 2007. In December 2011, T Plus was granted a license to provide 3G services in Cabo Verde. In October 
2012, a controlling interest in T Plus was acquired by Unitel Holdings, which is controlled by Mrs. Isabel dos Santos. 

CST, São Tomé and Principe 

Africatel owns 51% of the share capital of CST, which provides fixed and mobile services in São Tomé and Principe. As of 

December 31, 2017, CST had approximately 155,600 mobile customers. 

CST was established in 1989 and provides fixed-line and mobile telecommunications services under the terms of a 20-year license 

granted in 2007. CST began offering 3G services in São Tomé and Principe in March 2012 anticipating the connection of its network 
from the Africa Coast to Europe submarine cable which was inaugurated at the end of 2012. In March 2013, the General Regulatory 
Authority (Autoridade Geral de Regulação), the telecommunications regulator in São Tomé and Principe, granted the second license to 
provide fixed-line and mobile telecommunications services in São Tomé and Principe to Unitel Holdings, which is controlled by 
Mrs. Isabel dos Santos. The second operator commenced commercial activity in July 2014. 

Overview 

Regulation of the Brazilian Telecommunications Industry 

Our business, including the nature of the services we provide and the rates we charge, is subject to comprehensive regulation 
under the General Telecommunications Law and a comprehensive regulatory framework for the provision of telecommunications 
services promulgated by ANATEL. We provide fixed-line, domestic and international long-distance, mobile telecommunications, data 
transmission and Pay TV services under concessions, authorizations and licenses that were granted by ANATEL and allow us to 
provide specified services in designated geographic areas, as well as set forth certain obligations with which we must comply. See “— 
Concessions, Authorizations and Licenses.” 

ANATEL is a regulatory agency that was established in July 1997 pursuant to the General Telecommunications Law and 
ANATEL Regulation (Regulamento da Agência Nacional de Telecomunicações). ANATEL oversees our activities and enforces the 
General Telecommunications Law and the regulations promulgated thereunder. ANATEL is administratively independent and is 
financially autonomous. ANATEL is required to report on its activities to the Brazilian Ministry of Communications. ANATEL has 
authority to propose and to issue regulations that are legally binding on telecommunications service providers. ANATEL also has the 
authority to grant concessions and licenses for all telecommunications services, other than broadcasting services. Any regulation or 
action proposed by ANATEL is subject to a period of public comment, which may include public hearings, and ANATEL’s decisions 
may be challenged administratively before the agency itself or through the Brazilian judicial system. 

Concessions and Authorizations 

The current regulatory framework for the Brazilian telecommunications industry was adopted in 1998. Under the General 

Telecommunications Law and ANATEL regulations, the right to provide telecommunications services is granted either through a 
concession under the public regime (as discussed below) or an authorization under the private regime (as discussed below). A 
concession is granted for a fixed period of time following a public auction and is generally renewable only once. An authorization is 
granted for an indeterminate period of time and public auctions are held for some authorizations. These concessions and authorizations 
allow service providers to provide specific services in designated geographic areas, set forth certain obligations with which the service 
providers must comply and require equal treatment of customers by the service providers.

The three principal providers of fixed-line telecommunications services in Brazil, Telefônica Brasil, Claro and our company, 

provide these services under the public regime. In addition, CTBC and Sercomtel, which are secondary local fixed-line 
telecommunications service providers, operate under the public regime. All of the other providers of fixed-line telecommunications 
services and all providers of personal mobile services and data transmission services in Brazil operate under the private regime. 

Providers of public regime services are subject to more obligations and restrictions than providers of private regime services. 

Under Brazilian law, providers of public regime services are subject to certain requirements with respect to services such as network 
expansion and network modernization. Additionally, the rates that public regime service providers may charge customers are subject to 
ANATEL supervision. Another distinctive feature of public concessions is the right of the concessionaire to maintain certain economic 
and financial standards, which are calculated based on the rules set forth in our concession agreements and was designed based on a 
price cap model. The concessions are granted for a fixed period of time and are generally renewable only once.

Our concession agreements provide that ANATEL may modify their terms in 2015 and 2020 and may revoke them prior to 
expiration under the circumstances described below under “—Termination of a Concession.” The modification right permits ANATEL 
to impose new terms and conditions in response to changes in technology, competition in the marketplace and domestic and 
international economic conditions. ANATEL is obligated to engage in public consultation in connection with each of these potential 
modifications. 

On June 27, 2014, ANATEL opened a public comment period for the revision of the terms of our concession agreements. The 
comment period, which ended on December 26, 2014, was opened for comments on certain topics such as service universalization, rates 
and fees, among others. Throughout 2015, ANATEL, the Brazilian Ministry of Communications and telecommunications service 
providers met regularly to discuss possible amendments to each of the concession agreements granted by ANATEL, including ours, and 
the implications of the developments and demands in the telecommunications sector in recent years. In September 2015, the Brazilian 
Ministry of Communications created a working group to evaluate the status of the concessions and propose guidelines for the 
amendment of the concession agreements. In April 2016, the Brazilian Ministry of Communications issued a decree addressing 
guidelines for the establishment of a new regulatory framework for telecommunications, which were expected to be implemented by 
ANATEL through the conclusion of the concession amendments. In line with the provisions of PLC 79, these guidelines provided for, 
among other things, the expansion of broadband services (including in rural regions), the elimination of the reversibility of assets, and 
an extension of the terms of concessions, which in our case are currently scheduled to expire in 2025. As a result of the publication of 
these guidelines, ANATEL requested a further postponement of the review of our concession agreements, which was granted. The 
implementation of these guidelines, however, depends on the passage of PLC 79 to provide the necessary legal authority and 
framework. As a result of the Brazilian Congress’s failure to date to pass PLC 79, the review of our concession agreements, which was 
scheduled to occur by June 2017, has not yet taken place, and further discussions regarding amendments to our concession agreements 
have halted pending resolution of PLC 79. Under their existing terms, our concession agreements may be amended by December 2020 
at the latest. If PLC 79 is not passed, our concession agreements will expire in 2025 without the possibility of renewal. 

For more information about our concession agreements, see “—Concessions, Authorizations and Licenses—Fixed-Line and 

Domestic Long-Distance Services Concession Agreements.” 

In connection with the consideration of revisions to the concession agreements under the public regime, in January 2017, 

ANATEL proposed revisions to the terms of the General Plan of Grants, in line with the provisions of PLC 79, which include the ability 
of companies operating under a concession in the public regime to convert their concessions into authorizations to operate in the private 
regime and thereby eliminate a number of substantial obligations currently imposed by the concession regime, in exchange for the 
assumption of obligations to make additional investments in their networks, primarily related to the expansion of broadband services or 
through the payment of fees to ANATEL. The value of the obligations currently imposed by the concession agreement and, therefore, 
the cost of the additional investments or fees to be paid to ANATEL in exchange for the elimination of such obligations, would be 
subject to discussion between the parties, with ANATEL having the ability to make the final valuation. However, as a result of the 
legislative gridlock faced by PLC 79, ANATEL has halted implementation of the General Plan of Grants. For more information about 
PLC 79 and ANATEL’s proposed revisions to the terms of the General Plan of Grants, see “—Other Regulatory Matters—New 
Regulatory Framework.”

We cannot assure you that any future amendments to our concession agreements or the General Plan of Grants will not impose 

requirements on our company that will require us to undertake significant capital expenditures or will not modify the rate-setting 
procedures applicable to us in a manner that will significantly reduce the net operating revenue that we generate from our Brazilian 
fixed-line businesses. If the amendments to our Brazilian concession agreements have these effects, our business, financial condition 
and results of operations could be materially adversely affected. In addition, PLC 79 has faced political gridlock in the Brazilian 
Congress and has not yet been passed, and we cannot predict whether this legislation will ultimately be adopted by the Brazilian 
Congress and executed by the President or whether the features of this modification of the regulatory scheme will be adopted as 
proposed. We continue to analyze the potential effects of this modification of the regulatory scheme on our business, capital 
expenditure obligations, results of operations, cash flows and financial position and whether we would seek to convert our concessions 
into authorizations should this feature of the proposed modifications be adopted, but are unable to predict with any certainty the effects 
of this modification on our company, if adopted. Should this modification be adopted, many provisions of the proposed legislation 
would only have effects on our business following a rule-making procedure by ANATEL to implement the modifications to the 
regulatory scheme. We cannot predict the form of these new regulations or the time required for ANATEL to propose or adopt these 
regulations. 

Providers of private regime services, although not generally subject to the requirements concerning continuity and universality of 

service and network modernization, are subject to certain network expansion and quality of service obligations set forth in their 
respective authorizations. 

Under the concession agreements and authorizations, each of the service providers is required to comply with the provisions of 
(1) the General Plan on Universal Service Goals that was adopted by ANATEL in June 2011, (2) the General Plan on Quality Goals that 
was adopted by ANATEL in June 2013, and (3) the General Plan on Competition Targets that was adopted by ANATEL in November 
2012. Regulatory provisions are included in the relevant concession agreements and authorizations, and the service providers are 
subject to public service principles of continuity, changeability and equal treatment of customers. 

In addition, ANATEL is authorized to direct and control the provision of services, to apply penalties and to declare the expiration 

of the concession and the return of assets from the concessionaire to the government authority upon termination of the concession. 

Regulation of Fixed-Line Services 

Rate Regulation 

Under the concession agreements, public regime service providers are required to offer basic local fixed-line plans to users. Rates 
for long-distance services originated and terminated on fixed lines vary in accordance with certain criteria. The concession agreements 
establish a price-cap mechanism for annual rate adjustments for basic service plans and domestic long-distance rates based on formulas 
set forth in each provider’s concession agreement. The formula provides for two adjustments to the price cap based on the local rate 
basket, the long-distance rate basket and the use of a price index. The price cap is first revised upward to reflect increases in inflation, as 
measured by an index, then ANATEL applies a productivity discount factor, or Factor X, which reduces the impact of the rate 
readjustment provided by the index. 

ANATEL has calculated the sector’s weighted average productivity rate. As of the date of this annual report, Factor X is equal to 

(1) 50% of the increase in the weighted average productivity rate of public regime providers, plus (2) 75% of a factor calculated by 
ANATEL that is designed to reflect cost optimization targets for the telecommunications industry as a whole. If the weighted average 
productivity rate is negative, ANATEL will not allow an annual adjustment in excess of the IST. 

ANATEL has proposed new regulations under which it would modify the Factor X applicable to the determination of rate 
increases available to public concessionaires providing fixed-line services. In October 2017, ANATEL passed Resolution No. 684, 
which modifies the Factor X applicable to the determination of rate increases available to public concessionaires providing fixed-line 
services. However, this resolution will only take effect only after the publication of an Act of the Superintendent of ANATEL, which 
we expect to happen in the first half of 2018. 

A provider may increase rates for individual services within the local rate basket or the long-distance rate basket by up to 5% more 

than the IST so long as the rates for other services in that rate basket are reduced to the extent necessary to ensure that the weighted 
average increase for the entire rate basket does not exceed the permitted annual rate adjustment.

A provider may also offer alternative plans in addition to the basic service plan. Alternative plans must be submitted for 

ANATEL’s approval. The rates offered under the alternative plans may be adjusted annually based on the IST. 

For information on our rates and service plans, see “—Rates.” 

General Plan on Universal Service Goals 

The General Plan on Universal Service Goals, as amended, was approved by ANATEL in June 2011. The General Plan on 

Universal Service Goals sets forth the principal network expansion and modernization obligations of the public regime providers. 

Public regime providers are subject to network expansion requirements under the General Plan on Universal Service Goals, which 

are revised by ANATEL from time to time. No subsidies or other supplemental financings are anticipated to finance our network 
expansion obligations. Our failure to meet the network expansion and modernization obligations established by the General Plan on 
Universal Service Goals or in our concession agreements may result in fines and penalties of up to R$50 million, as well as potential 
revocation of our concessions. 

The General Plan on Universal Service Goals requires the following, among other things: 

•

•

•

local fixed-line service providers to provide individual access to fixed-line voice services to economically disadvantaged 
segments of the Brazilian population within their service areas, through programs to be established and regulated by 
ANATEL; 

local fixed-line service providers to provide public telephones in urban areas within their service areas, including in localities 
with a population in excess of 100, and to install residential fixed lines within seven days of a request in localities with a 
population in excess of 300; and 

local and long-distance fixed-line providers that obtain authorizations to use radio spectrum in the 450 Mhz band to provide 
universal service in rural and remote areas, as well as to provide individual and group access to fixed-line voice services. 

Similarly to the 2012 amendments to the General Plan on Universal Service Goals that eliminated the requirements to provide 

public telephone centers (postos de serviço telefônico) in exchange an increase backhaul capacity, ANATEL has proposed new 
amendments to the General Plan on Universal Service Goals to eliminate the requirements to provide multifacility service centers 
(postos de serviço multifacilidade), which are public centers that offers various telecommunications services, including voice, access to 
the internet and digital transmission of text and images, and to install and maintain public telephones within a fixed-line service 
concession, in exchange for other obligations to be defined. The value of the obligations currently imposed by the General Plan on 
Universal Service Goals and, therefore, the cost of the additional investments or fees to be paid to ANATEL in exchange for the 
elimination of such obligations, is subject to discussion between the parties, with ANATEL having the ability to make the final 
valuation. These amendments are under analysis of ANATEL and the Brazilian Ministry of Communications, and we believe that the 
executive decree approving the new General Plan on Universal Service Goals will be issued by the end of 2018. 

Service Restrictions 

Pursuant to regulations in effect as of the date of this annual report, public regime providers are subject to certain restrictions on 

alliances, joint ventures and mergers and acquisitions with other public regime providers, including: 

•

•

a prohibition on holding more than 20% of the voting shares of more than one other provider of public regime services; and 

a restriction on mergers between regional fixed-line service providers. 

In December 2010, ANATEL adopted new regulations eliminating the limitation on the number of authorizations to provide 
subscription television services. In September 2011, Law No. 12,485 became effective, which creates a new legal framework for 
subscription television services in Brazil, replacing and unifying the previously existing regulatory provisions that governed various 
forms of subscription television services, such as cable television, Multichannel Multipoint Distribution Service, or MMDS, and DTH. 
The principal provisions of Law No. 12,485: 

•

•

•

allow fixed-line telephone concessionaires, such as us, who previously were allowed to provide subscription television 
services using only MMDS and DTH technologies, to enter the cable television market in Brazil; 

remove existing restrictions on foreign capital investments in cable television providers; 

establish minimum quotas for domestic content programming on every television channel;

limit the total and voting capital held by broadcast concessionaires and authorized providers, and in television programmers 
and producers, with headquarters in Brazil to 30%; and 

prohibit telecommunications service providers with collective interests from acquiring rights to disseminate images of events 
of national interest and from hiring domestic artistic talent. 

The framework established by Law No. 12,485 increased the availability and lowered the price of subscription television services 

in Brazil, through increased competition among providers, and improved the quality, speed and availability of broadband internet 
services as a result of the expected proliferation of fiber optic cables used to transmit cable television. 

In March 2012, ANATEL adopted new regulations under which the authorizations to provide various existing subscription 
television services have been consolidated into authorizations to provide a newly-defined service called Conditional Access Service. 
Under these regulations, authorizations to provide Conditional Access Service apply to private telecommunications services, the receipt 
of which are conditioned on payment by subscribers, for the distribution of audiovisual contents in the form of packages, individual 
channels and channels with required programming, by means of any communications technology, processes, electronic means or 
protocols. An authorization granted by ANATEL to provide Conditional Access Service will be valid for the entire Brazilian territory; 
however, the provider must indicate in its application for an authorization the localities that it will service. In December 2012, 
ANATEL granted our request to convert our DTH authorization agreement into a Conditional Access Service authorization. In 
September 2014, we entered into a Conditional Access Service authorization agreement with ANATEL that authorized us to offer the 
services to be governed by such agreement, including IP TV. 

Ownership and Corporate Governance Restrictions 

In connection with the RJ Proceedings, ANATEL gained expanded powers regarding our ownership and corporate governance 

decisions. 

On November 8, 2016, ANATEL issued an order in which it, among other things, (1) suspended the exercise of voting and veto 
rights by the members of Oi’s board of directors appointed by Société Mondiale, (2) prohibited the participation of members of Oi’s 
board of directors appointed by Societé Mondiale in Oi’s board of directors, and (3) ordered Oi to notify the Superintendence of 
Competition of ANATEL of the dates of meetings of Oi’s board of directors so that it could send a representative to attend such 
meetings. 

On July 14, 2016, the RJ Court granted a request made by ANATEL that the RJ Court determine that prior approval from 

ANATEL is required for, among other things, the possible transfer of Oi’s corporate control, including the replacement of Oi’s board of 
directors. 

On January 6, 2017, ANATEL issued an additional order conditioning its approval of the entry of Société Mondiale into Oi’s 
controlling block on the continued compliance with this obligation, among others, as well as the submission of any changes to Oi’s 
board of directors, including changes with respect to alternate members, for the prior approval by ANATEL. 

On January 15, 2018, ANATEL approved Oi’s transitional board of directors appointed pursuant to the RJ Plan. 

Termination of a Concession 

ANATEL may terminate the concession of any public regime telecommunications service provider upon the occurrence of any of 

the following: 

•

•

•

•

•

an extraordinary situation jeopardizing the public interest, in which case the Brazilian government is authorized to start 
rendering the services set forth under the concession in lieu of the concessionaire, subject to congressional authorization and 
payment of adequate indemnification to the owner of the terminated concession; 

termination by the provider (through an agreement with ANATEL or pursuant to legal proceedings) as a consequence of an 
act or omission of the Brazilian government that makes the rendering of the services excessively burdensome to the provider; 

annulment of the concession due to a contractual term, which is deemed by subsequent law to be illegal; 

material failure to comply with the provider’s universalization targets;

a split-up, spin-off, amalgamation, merger, capital reduction or transfer of the provider’s control without ANATEL’s 
authorization; 

the transfer of the concession without ANATEL’s authorization; 

the dissolution or bankruptcy of the provider; or 

an extraordinary situation in which Brazilian government intervention, although legally permissible, is not undertaken, as 
such intervention would prove to be inconvenient, unnecessary or would result in an unfair benefit to the provider. 

In the event a concession is terminated, ANATEL is authorized to administer the provider’s properties and its employees in order 

to continue rendering services. 

Over the years, ANATEL has initiated several internal proceedings to monitor our financial situation and to evaluate our ability to 

continue to perform our obligations under our concession agreements. In light of the approval of the RJ Plan by the creditors on 
December 20, 2017, and its subsequent ratification and confirmation by the RJ Court, ANATEL began to monitor our operating and 
financial positions based on the effectiveness of the RJ Plan. 

General Plan on Quality Goals 

The General Plan on Quality Goals was approved by ANATEL in December 2012 and became effective in June 2013. Each fixed-

line service provider operating under the public regime or the private regime must comply with the provisions of the General Plan on 
Quality Goals. All costs related to compliance with the quality goals established by the General Plan on Quality Goals must be borne 
exclusively by the service provider. The General Plan on Quality Goals establishes minimum quality standards with regard to: 

•

•

•

•

•

modernization of the network; 

responses to repair requests; 

responses to change of address requests; 

rate of call completion; and 

quality of public telephones. 

These quality standards are measured according to the definitions and quality indicators established by ANATEL. Every month, 

fixed-line service providers are required to report their compliance with quality goals to ANATEL. In 2018, we began to collect quality 
data directly from broadband modems and smartphones, which we believe will allow us to take more accurate quality measurements 
and reduce disputes with ANATEL regarding compliance. 

ANATEL measures the performance of fixed-line service providers in each individual state in which they operate. As a result, the 

performance of fixed-line service providers in any particular state may not meet one or more quality performance targets even if such 
service provider’s overall performance is satisfactory. Therefore, fixed-line service providers, including us, could be subject to fines or 
penalties as a result of the failure to meet the quality performance targets in one or more particular states. 

Regulation of Mobile Services 

In September 2000, ANATEL adopted regulations that established operating rules for providers under the personal mobile service 

(Serviço Móvel Pessoal) regime. The regulations permitted ANATEL to grant authorizations to provide mobile telecommunications 
services under the personal mobile service regime. For purposes of the personal mobile service regulations, Brazil is divided into three 
service regions covering the same geographic areas as the concessions for fixed-line telecommunications services.

Auction of 3G Spectrum 

In preparation for auctions of spectrum in Bands F, G, I and J (2.1 GHz), the use of which allows personal mobile services 
providers to offer 3G services to their customers, ANATEL issued regulations that divide the Brazilian territory into nine regions for 
purposes of operations using these frequency bands. In December 2007, ANATEL auctioned radio frequency licenses to operate on 
each of these frequency bands in each of the nine regions and the related licenses to use these frequency bands. In this auction, we 
acquired the radio frequency licenses necessary to offer 3G services in two of the nine regions delineated by ANATEL for 3G services 
(corresponding to Regions II under the personal mobile services regime) and TNL PCS acquired radio frequency licenses necessary to 
offer 3G services in six of the nine regions delineated by ANATEL for 3G services (corresponding to Regions I and III under the 
personal mobile services regime, other than an area that consists of 23 municipalities in the interior of the State of São Paulo that 
includes the city of Franca and surrounding areas). 

Authorizations to Use 450 MHz Band and 2.5 GHz Band 

In preparation for auctions of the 450MHz band and 2.5 GHz band, the use of which allows personal mobile services providers to 
offer 4G services to their customers, ANATEL issued regulations that divided the Brazilian territory into three regions for purposes of 
providing personal mobile services. In June 2012, ANATEL auctioned radio frequency licenses to operate and the related licenses to 
use the frequency bands in the following manner: (1) four national lots for 2.5 GHz bands, each accompanied by a regional band of 450 
MHz, and (2) 132 regional lots for 2.5GHz bands. In this auction, we acquired (1) one of the national lots for 2.5 GHz and the 
corresponding regional lot of 450MHz to provide rural broadband services in the States of Goiás, Mato Grosso, Mato Grosso do Sul, 
Rio Grande do Sul and the Federal District, and (2) 11 regional lots for 2.5 GHz bands to provide personal mobile services in the 
following areas: interior of Ceará, the capital or Roraima (and its metropolitan area), the State of Amapá, the capital of Bahia (and its 
metropolitan area), interior of the State of Pará, the capital of Pernambuco (and its metropolitan area), interior of Paraná, the capital of 
Rio Grande do Sul (and its metropolitan area), the City of Jaguarão (and its metropolitan area) and the capital of São Paulo (and its 
metropolitan area. In July 2013, ANATEL and CADE approved the RAN Sharing Agreement between TIM and Oi for the construction, 
implementation and mutual assignment of network tools to support personal mobile services (voice and broadband) in the 2.5 GHz 
band, among others, in order to ensure compliance with the scope of commitments. In December 2015, ANATEL and CADE approved 
the RAN Sharing Agreement between Telefônica Brasil, TIM and Oi for the construction, implementation and mutual assignment of 
network tools to support personal mobile services (voice and broadband) in the 2.5 GHz band, among others, in order to ensure 
compliance with the scope of commitments. With respect to the latter agreement, ANATEL rejected the proposal to conduct RAN 
sharing in conurbations, however, because it detected interference in the service. As a result, ANATEL will not allow RAN sharing in 
municipalities experiencing interference until a solution has been found. 

Obligations of Personal Mobile Services Providers 

As a telecommunications service provider, we are subject to requirements concerning network expansion and quality of service, as 
established in applicable regulations and in our personal mobile services authorizations. If we fail to meet these obligations, we may be 
fined, subject to a maximum penalty of R$50 million, until we are in full compliance with our obligations. While it is possible for an 
authorization to be revoked for non-compliance with these obligations, there are no precedents for such a revocation. 

Quality of Service Obligations 

Our personal mobile services authorizations impose obligations on us to meet quality of service standards relating to our 

network’s ability to make and receive calls, call failure rates, capacity to handle peak periods, failed interconnection of calls and 
customer complaints. ANATEL defines this quality of service standards, and we must report information in connection with such 
standards to ANATEL. 

To restructure the process of assessing the quality of mobile service, with the inclusion of new processes and measurement of new 
indicators to check the quality of mobile broadband and the quality perceived by the user, and the modernization of existing indicators, 
ANATEL approved the Regulation for the Management of Quality of Provision of Personal Mobile Service (Regulamento de Gestão da 
Qualidade da Prestação de Serviço Móvel Pessoal), or SMP-RGQ. The SMP-RGQ provides for the assessment of the network 
connection and their respective data transmission rate, assessing aspects of availability, stability and connection speed for the data 
network. Targets are defined as 80% of speed hired (on average per month) by users and 40% of the instant speed, according to the 
definitions of the Resolution 575/2011.

In January 2018, ANATEL adopted a new model for measuring the quality of mobile broadband networks through the use of 
smartphones, replacing the previous model that required data from volunteers and often led to statistically insignificant results. The new 
model, which we have adopted by collecting user data directly from smartphones using the Minha Oi application, allows us to better 
manage the quality of our network, allowing us to identify corrective actions and more efficiently direct investments in our network. 

Interconnection Regulations 

Under the General Telecommunications Law, all telecommunications service providers are required, if technically feasible, to 

make their networks available for interconnection on a non-discriminatory basis whenever a request is made by another 
telecommunications service provider. Interconnection permits a call originated on the network of a requesting fixed-line or personal 
mobile services provider’s network to be terminated on the fixed-line or personal mobile services network of the other provider. 
ANATEL has adopted General Rules on Interconnection (Regulamento Geral de Interconexão) to implement these requirements. 

Interconnection Regulations Applicable to Fixed-Line Providers 

Interconnection fees are charged at a rate per minute of use of a fixed-line provider’s network. Interconnection rates charged by a 

fixed-line provider to terminate a call on its local network (the TU-RL rate) or intercity network (the TU-RIU rate) are subject to a price 
cap established by ANATEL. The price cap for interconnection rates varies from service provider to service provider based on the retail 
prices of each service provider. 

Fixed-line service providers must offer the same TU-RL and TU-RIU rates to all requesting providers on a nondiscriminatory 
basis. The price caps on interconnection rates are adjusted annually by ANATEL at the same time that rates for local and long-distance 
calls are adjusted. 

Under ANATEL regulations, fixed-line service providers are not able to charge other fixed-line service providers for local fixed-

line calls originating on their local fixed-line networks and terminating on the other provider’s local fixed-line networks. 

In July 2014, ANATEL published the maximum fixed reference rates, including TU-RL and TU-RIU, for entities with significant 

market power, such as our company, for 2016 through 2019. For more information about TU-RL and TU-RIU rates, see 
“—Rates—Network Usage (Interconnection) Rates—Fixed-Line Networks.” 

Interconnection Regulations Applicable to Personal Mobile Services Providers 

Interconnection fees are charged at a flat rate per minute of use of a personal mobile services provider’s network. The terms and 
conditions of interconnection agreements of all personal mobile services providers, including the rates charged by the operator of the 
network to terminate a call on its mobile network (the MTR rate), commercial conditions and technical issues, are freely negotiated 
between mobile and fixed-line telecommunications service providers, subject to compliance with regulations established by ANATEL 
relating to traffic capacity and interconnection infrastructure that must be made available to requesting providers, among other things. 

Personal mobile services providers must offer the same MTR rate to all requesting providers on a nondiscriminatory basis. 

Interconnection agreements must be approved by ANATEL before they become effective and may be rejected if they are contrary to the 
principles of free competition and the applicable regulations. If the providers cannot agree upon the terms and conditions of 
interconnection agreements, ANATEL may determine terms and conditions by arbitration. Since no agreement with fixed-line service 
providers could be reached regarding MTR rates when we began offering personal mobile services, ANATEL set the initial MTR rates. 

Personal mobile services providers negotiate annual rate increases for their MTR charges with the fixed-line telecommunications 

providers. If the providers cannot agree upon the terms and conditions of annual rate increases, ANATEL may determine the annual rate 
increases by arbitration. In July 2014, ANATEL published the maximum MTR reference rates for entities with significant market 
power, such as our company. For more information about MTR rates, see “—Rates—Network Usage (Interconnection) Rates—Mobile 
Networks.”

Consumer Protection Regulation 

In March 2014, ANATEL published a regulation approving the General Regulation on Telecommunications Customers Rights 
(Regulamento Geral de Direitos do Consumidor de Serviços de Telecomunicações), a single regulation for the telecommunications 
sector with general rules for customer service, billing, and service offers, which are applicable to fixed, mobile, broadband and Pay-TV 
customers. This regulation establishes a period ranging from 120 days to 24 months from the date of publication for entering into 
compliance with the new rules. Most of the new rules that expand the rights of those who use the telecommunications services entered 
into force on July 8, 2014. Our failure to comply with this regulation may result in various fines and penalties being imposed on us by 
ANATEL. 

Number Portability Regulations 

Number portability is the ability of a customer to move to a new home or office or switch service providers while retaining the 
same fixed-line or mobile telephone number. ANATEL’s General Regulation of Portability (Regulamento Geral de Portabilidade) 
establishes general rules regarding portability of fixed-line and mobile telephone numbers. These regulations permit fixed-line 
customers to retain their telephone numbers if they become customers of a different fixed-line service provider in the same municipality 
or if they move to a new home or office in the same municipality. Personal mobile services customers are permitted to retain their 
telephone numbers if they change their service plan or if they become customers of a different personal mobile services provider within 
the same registration area. Each telecommunications provider has been required to contract a third-party management entity to manage 
all procedures relating to number portability. Our failure to comply with these regulations may result in various fines and penalties 
being imposed on us by ANATEL. 

Regulation of Data Transmission and Internet Services 

Under Brazilian regulation, ISPs are deemed to be suppliers of value-added services and not telecommunications service 

providers. Value-added services are considered an activity that adds features to a telecommunications service supported by such value-
added services. Telecommunications service providers are permitted to render value-added services through their own networks. In 
addition, ANATEL regulations require all telecommunications service providers and cable television operators to grant network access 
to any party interested in providing value-added services, including internet access, on a non-discriminatory basis, unless not technically 
feasible. 

ANATEL has adopted regulations applicable to fixed-line service providers with significant market power. Under these 

regulations, these providers are required to make the forms of agreements that they use for EILD and SLD services publicly available, 
including the applicable rates, and are only permitted to offer these services under these forms of agreement. ANATEL publishes 
reference rates for these services, and if a customer of one of these providers objects to the rates which that provider charges for these 
services, the customer is entitled to seek to reduce the applicable rate through arbitration before ANATEL. 

In July 2014, ANATEL published reference rates for EILD services that contain a single reference table which will be valid from 

2016 until 2020, when rates reflecting a methodology that takes into consideration all long-run incremental costs, updated to current 
values, of providing a particular service and the unit costs of such service based on an efficient network considering the existing 
regulatory obligations, will apply. In addition, under the General Plan of Competition Targets, companies with significant market, such 
as our company, are required to present a public offer every six months including standard commercial conditions, which is subject to 
approval by ANATEL. 

Multimedia Communications Service Quality Management Regulations 

In June 2011, the President of Brazil issued Executive Decree No. 7,512/11, which mandated ANATEL to take the necessary 
regulatory measures to establish quality standards for broadband internet services. In compliance with such decree, on October 31, 
2011, ANATEL published a resolution approving the Multimedia Communications Service Quality Management Regulations 
(Regulamentação de Gestão da Qualidade do Serviço de Comunicação Multimídia), or the Regulations, which identify network quality 
indicators and establish performance goals for multimedia communications service providers, including broadband internet service 
providers, with more than 50,000 subscribers. Such providers will be required to collect representative data using dedicated equipment 
installed at the site of each network connection and be subject to periodic measurements to ensure their compliance with such 
regulations, including: 

•

•

individual upload and download speeds of at least 40% of contracted speeds per measurement for at least 95% of all 
measurements; 

average upload and download speeds of at least 80% of contracted speeds for all measurements; and

•

individual round-trip latencies for fixed-line connections of up to 80 milliseconds per measurement for at least 95% of the 
measurements. 

To increase transparency, customers must be provided with specialized software at no cost to measure their own network quality, 

although such customer-generated measurements will not be included in official calculations. In addition to ensuring network quality 
standards, service providers must hire specialized companies to measure customer service and customer satisfaction indicators, 
including complaint resolution, customer service personnel competence, customer perceptions relating to billing and quality of technical 
support staff. Service providers must comply with the above-mentioned quality standards beginning on the thirteenth month following 
implementation of such regulations. Failure to meet such standards will subject non-compliant service providers to sanctions. 

In January 2018, ANATEL adopted a new model for measuring the quality of mobile broadband networks through the use of 
broadband modems, replacing the previous model that required data from volunteers and often led to statistically insignificant results. 
The new model, which we have adopted by collecting user data directly from smartphones using the Minha Oi application, allows us to 
better manage the quality of our network, allowing us to identify corrective actions and more efficiently direct investments in our 
network. 

National Broadband Plan 

On June 30, 2011, we entered into a Term of Commitment (Termo de Compromisso) with ANATEL and the Brazilian Ministry of 

Communications to formalize our voluntary commitment to adhere to the terms of the National Broadband Plan, created in May 2010 
by Executive Decree No. 7,175/10 with the goal to make broadband access available at low cost, regardless of technology, throughout 
Brazil. Pursuant to the Term of Commitment, we are required to offer (1) broadband services with minimum upload and download 
capabilities to retail customers in certain sectors of Regions I and II for a maximum price of R$35 per month (or R$29.90 in ICMS-
exempt states), plus fees, and (2) access to our broadband infrastructure to certain wholesale customers, including small businesses and 
municipalities, in certain sectors of Regions I and II for a maximum price of R$1,253 per 2 Mbps per month and a one-time installation 
fee, while observing all quality standards under ANATEL regulations. Both retail and wholesale services are subject to certain network 
capacity limits and need only be provided at the demand of the customer. Pursuant to the Term of Commitment, we have offered the 
required services to all eligible retail and wholesale customers since the date of its execution and have gradually increased the capacities 
offered to wholesale customers since November 2011. We have been obligated to provide the maximum capacities established by the 
Term of Commitment to eligible wholesale customers since June 30, 2015. In addition, the Term of Commitment requires that we: 

•

•

•

provide one public internet access point for the first 20,000 inhabitants and one additional access point for each subsequent 
10,000 inhabitants, with a limit of six access points, at a speed of 2 Mbps, in each municipality that has only satellite service, 
free of charge and upon demand of such municipality; 

adequately advertise the services contemplated by the Term of Commitment and present to the Brazilian Ministry of 
Communications semi-annual reports detailing our marketing efforts; and 

make our best efforts to offer broadband services to retail customers at speeds of up to 5 Mbps, reaching the largest possible 
number of municipalities. 

The Term of Commitment expired on December 31, 2016 and has not been renewed. Although we believe that we are in 

compliance with all of our network scope and service performance obligations set forth under the Term of Commitment, as of the date 
of this annual report, ANATEL has yet to complete its review, and we cannot predict when it will do so. Our failure to meet our 
obligations may result in the imposition of penalties established in ANATEL regulations. 

Legal Framework for the Use of the Internet (Internet Bill of Rights) 

In April 2014, then-President Dilma Rousseff approved the Legal Framework for the Use of the Internet (Marco Civil da Internet), 

or the Internet Framework, which establishes the principles, guarantees, rights and duties for the use of the Internet in Brazil. The bill 
sets forth a number of guidelines and rules to be observed by internet and application service providers, such as the protection of 
privacy, the protection of personal data, the preservation and guarantee of net neutrality, the liability for damages caused by content 
generated or published by third parties and the storage and disclosure of usage logs. Certain parts of the Internet Framework went into 
effect on June 23, 2014 and others will become effective on the adoption of implementing regulations.

Under the Internet Framework, a presidential decree will be enacted to regulate the law’s provisions, and enacting specific rules 

regarding network traffic management techniques. The Brazilian Internet Steering Committee (Comitê Gestor da Internet) and 
ANATEL will express their opinion on the decree after public hearings. Brazil’s Ministry of Justice has also launched a public debate 
on the main themes related to this law. 

In November 2016, ANATEL released a questionnaire to evaluate the market demand for unlimited data plan offerings. Responses 

to this questionnaire were submitted by April 2017, and ANATEL is scheduled to study its results during the first semester of 2018. 

Other Regulatory Matters 

General Plan on Competition Targets 

The General Plan on Competition Targets, which was approved by ANATEL and became effective in November 2012, 

contemplates the creation of one entity to manage information about telecommunications networks, act as an intermediary in contracts 
between telecommunications providers and supervise the offering of wholesale data traffic services. The General Plan on Competition 
Targets also addresses a variety of other matters relating to both fixed-line and mobile service providers, including criteria for the 
evaluation of telecommunications providers to determine which providers have significant market power, regulations applicable to the 
wholesale markets for trunk lines, backhaul, access to internet backbone and interconnection services, and regulations related to partial 
unbundling and/or full unbundling of the local fixed-line networks of the public regime service providers. 

The General Plan on Competition Targets imposes stricter restrictions on providers that are deemed to have significant market 
power in a particular geographic area, ranging from a neighborhood within a municipality to the entire national territory. In order to 
determine whether a provider has significant market power, ANATEL established criteria that consider: 

•

•

•

•

that provider’s market share in particular mobile interconnection markets and personal mobile services market; 

the economies of scope and scale available to that provider; 

that provider’s dominance over infrastructure that is not economically viable to duplicate; and 

that provider’s concurrent operations in the wholesale and retail markets. 

In December 2016, ANATEL launched a public consultation process to review proposed changes to the General Plan on 
Competition Targets, including establishing new criteria to determine significant market power and creating a new competition 
framework. Under this new framework, municipalities will be categorized according to degree of competition present: competitive, 
moderately competitive, potentially competitive and not competitive. ANATEL will then regulate companies based on the degree of 
competition present in each municipality. The public consultation period expired in March 2017, and ANATEL is in the process of 
reviewing the proposed amendments, which we expect will become effective by the end of 2018. 

Infrastructure Sharing 

Prior to the adoption of the General Plan on Competition Targets, ANATEL had established rules for partial unbundling of the 
local fixed-line networks of the public regime service providers, which we refer to as “line sharing,” and which (1) limited the rates 
service providers can charge for line sharing, and (2) addressed related matters such as co-location space requirements. Co-location 
means that a service provider requesting unbundling may place its switching equipment in or near the local exchange of the service 
provider whose network the requesting service provider wishes to use and may connect to the network at this local exchange. 

The General Plan on Competition Targets requires public regime service providers that have significant market power, such as our 

company, to share their fixed-line network infrastructure with other providers, including their local fixed-line access networks. 
Providers that are deemed to have significant market power must offer (1) full unbundling of their copper wire or coaxial cable access 
networks, and (2) partial unbundling of their broadband networks to accommodate bitstreams of up to 10 Mbps. Providers with 
significant market power must also share their passive infrastructure, such as telecommunications towers, with other service providers 
at prices determined by bilateral negotiations between the providers.

Interconnection Regulations Applicable to Personal Mobile Services Providers 

The General Plan on Competition Targets established regulations for the rates charged by mobile service providers to terminate 
calls on their mobile networks (the MTR rate). The General Plan on Competition Targets established a reference value for MTR rates of 
providers that are deemed to hold significant market power. In July 2014, ANATEL published the maximum MTR reference rates for 
entities with significant market power, such as our company, for 2016 through 2019, when MTR rates reflecting a methodology that 
takes into consideration all long-run incremental costs, updated to current values, of providing a particular service and the unit costs of 
such service based on an efficient network considering the existing regulatory obligations, will apply. For more information about MTR 
rates, see “—Rates—Network Usage (Interconnection) Rates—Mobile Networks.” Beginning on February 24, 2016, each mobile 
service provider became entitled to collect the MTR on all calls for which its network was used to originate or terminate the call. 

In February 2015, ANATEL revised the General Plan on Competition Targets regulation relating to the MTR applicable to the 
relationship between companies with significant market power and companies without significant market power. Under the revised 
regulations, the dates and percentages applicable to the MTR partial bill-and-keep system were revised so that the MTR will be paid 
only when the traffic out of a network in a given direction is greater than: 

•

•

•

•

75% of the total traffic exchanged until February 23, 2016; 

65% of the total traffic exchanged until February 23, 2017; 

55% of the total traffic exchanged until February 23, 2018; and 

50% of the total traffic exchanged until February 23, 2019. 

The full billing system is scheduled to come into effect on February 24, 2019. 

Roaming 

Under the General Plan on Competition Targets, a mobile services provider with significant market power, such as our company, 

must offer roaming services to other mobile services providers without significant market power at the maximum rate that the mobile 
services provider with significant market power is permitting ANATEL to offer such services to its retail customers. 

In March 2017, ANATEL began a pilot program with the four principal mobile services providers, including our company, to 

share infrastructure costs to expand voice and data roaming services to 35 municipalities with fewer than 30,000 residents. As a result 
of this program, which is ongoing, the providers began or resumed discussions about voice and data roaming tariffs. As of the date of 
this annual report, the providers have not reached a consensus regarding roaming tariffs. 

Quality of Telecommunications Services Regulation 

In December 2017, ANATEL submitted for public consultation the Quality of Telecommunications Services Regulation 
(Regulamento de Qualidade dos Serviços de Telecomunicações – RQUAL), a proposal to revise the methods by which the quality 
standards for fixed-line services, personal mobility services, multimedia communications services and subscription television services 
required under the General Plan on Quality Goals are measured. Under the proposal, the quality indicators would be standardized and 
simplified for consumer use, with the goals of assisting consumers to make informed decisions about quality and improving competition 
for quality among telecommunications providers. The public consultation period ended in April 2018, and we expect that the Quality of 
Telecommunications Services Regulation will be approved by the end of 2018. 

Regulatory Agenda 2017-2018 

On January 6, 2017, ANATEL put in public consultation its proposed Regulatory Agenda for the 2017-2018. The proposal 
contains 56 topics of interest to the sector, which should have obtained final approval or a certain level of progress in 2017 and 2018. 
The listed items include: Revision of the Concession Agreement and General Plan on Universal Service Goals, review of the quality 
management model, review of spectrum management model, review the arrangements and scope of telecommunications services,

New Regulatory Framework 

On November 23, 2015, the Brazilian Ministry of Communications opened public consultation on the new regulatory framework 

for telecommunications. The consultation was based on a series of questions under four basic topics: purpose of the public policy, 
universal policy, public regime versus the private regime and public concession. In April 2016, the Brazilian Ministry of 
Communications issued a decree addressing guidelines for the establishment of a new regulatory framework for telecommunications to 
be implemented by ANATEL. The guidelines provide for, among other things, the expansion of broadband services (including in rural 
regions), the elimination of the reversibility of assets, and an extension of the term of our concessions, which are currently scheduled to 
expire in 2025. 

In December 2016, PLC 79 was introduced in the Brazilian Congress to substantially amend certain features of the General 
Telecommunications Law, based substantially on the guidelines outlined in the decree of the Brazilian Ministry of Communications. 
Among the proposed changes to the regulatory regime is a proposal to permit companies operating under a concession in the public 
regime to convert their concessions into authorizations to operate in the private regime and to eliminate the reversibility of assets. As 
proposed, this modification of the regulatory scheme would permit concessionaires, by converting their concessions to authorizations, 
to eliminate a number of substantial obligations currently imposed by the concession regime in exchange for the assumption of 
obligations to make additional investments in their networks, primarily related to the expansion of broadband services or through the 
payment of fees to ANATEL. The value of the obligations currently imposed by the concession agreement and, therefore, the cost of the 
additional investments or fees to be paid to ANATEL in exchange for the elimination of such obligations, would be subject to 
discussion between the parties, with ANATEL having the ability to make the final valuation. In addition to the proposed changes to the 
regulatory framework for the public regime, the proposed legislation provides that (1) the initial terms of radio frequency authorizations 
and licenses would be increased from 15 years to 20 years, (2) these authorizations and licenses, which currently are only eligible for a 
single 15-year renewal, would be permitted to be renewed for successive 20-year terms, and (3) the concessions of telecommunications 
services under the public regime which are only eligible for a single 20-year renewal would be permitted to be renewed for successive 
20 year terms. 

PLC 79 has faced political gridlock in the Brazilian Congress and has not yet been passed, and we cannot predict whether this 

legislation will ultimately be adopted by the Brazilian Congress and executed by the President or whether the features of this 
modification of the regulatory scheme will be adopted as proposed. We continue to analyze the potential effects of this modification of 
the regulatory scheme on our business, capital expenditure obligations, results of operations, cash flows and financial position and 
whether we would seek to convert our concessions into authorizations should this feature of the proposed modifications be adopted, but 
are unable to predict with any certainty the effects of this modification on our company, if adopted. Should this modification be 
adopted, many provisions of the proposed legislation would only have effects on our business following a rule-making procedure by 
ANATEL to implement the modifications to the regulatory scheme. We cannot predict the form of these new regulations or the time 
required for ANATEL to propose or adopt these regulations. 

In January 2017, ANATEL proposed revisions to the terms of the General Plan of Grants (Plano Geral de Metas de Outorgas), in 
line with the provisions of PLC 79, which include the ability of companies operating under a concession in the public regime to convert 
their concessions into authorizations to operate in the private regime and thereby eliminate a number of substantial obligations currently 
imposed by the concession regime, in exchange for the assumption of obligations to make additional investments in their networks, 
primarily related to the expansion of broadband services or through the payment of fees to ANATEL. The value of the obligations 
currently imposed by the concession agreement and, therefore, the cost of the additional investments or fees to be paid to ANATEL in 
exchange for the elimination of such obligations, would be subject to discussion between the parties, with ANATEL having the ability 
to make the final valuation. However, as a result of the Brazilian Congress’s failure to date to pass PLC 79, ANATEL has halted 
implementation of the General Plan of Grants. 

Environmental and Other Regulatory Matters in Brazil 

As part of our day-to-day operations, we regularly install ducts for wires and cables and erect towers for transmission antennae. 

We may be subject to federal, state and/or municipal environmental licensing requirements due to the installation of cables along 
highways and railroads, over bridges, rivers and marshes and through farms, conservation units and environmental preservation areas, 
among other places. As of the date of this annual report, we have been required to obtain environmental licenses for the installation of 
transmission towers and antennae in several municipalities with no material impact on our operations. However, there can be no 
assurances that other state and municipal environmental agencies will not require us to obtain environmental licenses for the installation 
of transmission towers and antennae in the future or that such a requirement would not have a material adverse effect on the installation 
costs of our network or on the speed with which we can expand and modernize our network.

We must also comply with environmental legislation regarding the management of solid waste. According to resolutions adopted 

by the National Environmental Council (Conselho Nacional do Meio Ambiente), companies responsible for the treatment and final 
disposal of solid industrial waste, special waste and solid urban waste are subject to environmental licensing. Should the waste not be 
disposed of in accordance with standards established by environmental legislation, the company generating such waste may be held 
jointly and severally liable with the company responsible for waste treatment for any damage caused. Also, in all states where we 
operate, we have implemented management procedures promoting the recycling of batteries, transformers and fluorescent lamps. 

In addition, we are subject to ANATEL regulations that impose limits on the levels and frequency of the electromagnetic fields 

originating from our telecommunications transmissions stations. 

We believe that we are in compliance with ANATEL standards as well as with all applicable environmental legislation and 

regulations. 

Disclosure Pursuant to Section 219 of the Iran Threat Reduction and Syria Human Rights Act 

Section 219 of the Iran Threat Reduction and Syria Human Rights Act of 2012 added Section 13(r) to the Exchange Act. 

Section 13(r) requires an issuer to disclose in its annual or quarterly reports filed with the SEC whether the issuer or any of its affiliates 
has knowingly engaged in certain activities, transactions or dealings with the Government of Iran, relating to Iran or with designated 
natural persons or entities involved in terrorism or the proliferation of weapons of mass destruction during the period covered by the 
annual or quarterly report. Disclosure is required even when the activities were conducted outside the United States by non-U.S. entities 
and even when such activities were conducted in compliance with applicable law. 

In December 2011, we entered into a roaming agreement with MTN Irancell. Pursuant to such roaming agreement, our customers 

are able to roam in MTN Irancell’s network (outbound roaming) and customers of MTN Irancell are able to roam in our network 
(inbound roaming). For outbound roaming, we pay MTN Irancell roaming fees for use of their network by our customers, and for 
inbound roaming MTN Irancell pays us roaming fees for use of our network by its customers. 

Our inbound and outbound roaming services with MTN Irancell were launched commercially in October and November 2012, 

respectively. During 2017, we recorded revenues of R$3,127 and expenses of R$115 in connection with this roaming agreement. 
During 2016, we recorded revenues of R$2,625 and expenses of R$11 in connection with this roaming agreement. 

We do not maintain any bank accounts in Iran. All payments in connection with our international roaming agreements are effected 

through our bank accounts in London. 

The purpose of all of these agreements is to provide our customers with coverage in areas where we do not own networks. For that 

purpose, we intend to continue maintaining these agreements. 

We also provide telecommunications services in the ordinary course of business to the Embassy of Iran in Brasilia. In 2017 and 

2016, we recorded gross revenues of R$32,076 and R$30,634, respectively, from these services. As one of the primary providers of 
telecommunications services in Brasilia, we intend to continue providing such services, as we do to the embassies of many other 
nations.

We are one of the principal integrated telecommunications service providers in Brazil with approximately 59.7 million RGUs as of 

December 31, 2017. We operate throughout Brazil and offer a range of integrated telecommunications services that include fixed-line 
and mobile telecommunication services, network usage (interconnection), data transmission services (including broadband access 
services), Pay-TV (including as part of double-play, triple-play and quadruple-play packages), internet services and other 
telecommunications services for residential customers, small, medium and large companies and governmental agencies. We own 
355,273 kilometers of installed fiber optic cable, distributed throughout Brazil. Our mobile network covers areas in which 
approximately 90.2% of the Brazilian population lives and works. According to ANATEL, as of December 31, 2017, we had a 16.5% 
market share of the Brazilian mobile telecommunications market and a 33.1% market share of the Brazilian fixed-line market. During 
2017, we recorded net operating revenue of R$23,790 million and a loss of R$4,028 million, and during 2016, we recorded net 
operating revenue of R$25,996 million and a loss of R$15,680 million. 

Our results of operations and financial condition have been and will be significantly influenced in future periods by the RJ 
Proceedings, our disposition of PT Portugal and our investment in Africatel. In addition, our results of operations for the years ended 
December 31, 2017, 2016 and 2015 and our financial condition as of December 31, 2017 and 2016 have been influenced, and our future 
results of operations and financial condition will continue to be influenced, by a variety of factors, including: 

•

•

•

•

•

•

•

•

•

the evolution of Brazilian GDP, which grew by 1.0% in 2017 and declined by 3.5% in each of 2016 and 2015, which we 
believe affects demand for our services and, consequently, our net operating revenue; 

the number of our fixed lines in service, which declined to 12.9 million as of December 31, 2017 and 13.7 million as of 
December 31, 2016 from 14.5 million as of December 31, 2015 (excluding fixed-line customers of our discontinued 
operations), and the percentage of our fixed-line customers that subscribe to our alternative plans which decreased to 85.4% 
as of December 31, 2017 and 85.5% as of December 31, 2016 from 86.4% as of December 31, 2015; 

the number of our mobile customers, which declined to 39.0 million as of December 31, 2017 and 42.2 million as of 
December 31, 2016 from 48.1 million as of December 31, 2015 (excluding fixed-line customers of our discontinued 
operations); 

the number of our fixed-line customers that subscribe to our broadband services, which declined to 5.6 million as of 
December 31, 2017 from 5.7 million as of December 31, 2016 and 2015 (excluding fixed-line customers of our discontinued 
operations); 

the number of our Pay-TV customers, which grew to 1.5 million as of December 31, 2017 and 1.3 million as of 
December 31, 2016 from 1.2 million as of December 31, 2015 (excluding fixed-line customers of our discontinued 
operations); 

the increased competition in the Brazilian market for telecommunications services, which affects the amount of the discounts 
that we offer on our service rates and the quantity of services that we offer at promotional rates; 

inflation rates in Brazil, which were 2.9% in 2017, 6.3% in 2016 and 10.6% in 2015, as measured by the IST, and the 
resulting adjustments to our regulated rates in Brazil, as well as the effects of inflation on our real-denominated debt that is 
indexed to take into account the effects of inflation or bears interest at rates that are partially adjusted for inflation; 

our compliance with our quality of service obligations under the General Plan on Quality Goals and our network expansion 
and modernization obligations under the General Plan on Universal Service Goals and our concession agreements, the 
amount of the fines assessed against us by ANATEL for alleged failures to meet these obligations and our success in 
challenging fines that we believe are assessed in error; and 

changes in the exchange rates of the real against the U.S. dollar, including the 1.5% depreciation of the real against the U.S. 
dollar during 2017, the 16.5% appreciation of the real against the U.S. dollar during 2016, and the 47.0% depreciation of the 
real against the U.S. dollar during 2015, which has affected the cost in reais of a substantial portion of the network 
equipment that we purchase for our capital expenditure projects, the prices of which are denominated in U.S. dollars or are 
U.S. dollar-linked.

We have prepared our consolidated financial statements as of December 31, 2017 and 2016 and for the years ended December 31, 

2017, 2016 and 2015 in accordance with U.S. GAAP, under the assumption that we will continue as a going concern. 

Under U.S. GAAP, our management is required to assess whether there are conditions or events, considered in the aggregate, that 

raise substantial doubt about our ability to continue as a going concern within one year after our financial statements are issued. Our 
management’s assessment of our ability to continue as a going concern is discussed in note 1 to our consolidated financial statements 
included in this annual report. As of December 31, 2017, our management had taken relevant steps in the RJ Process, particularly the 
preparation, presentation and approval of the RJ Plan, which allows our viability and continuity, and the approval of the RJ Plan by our 
creditors on December 20, 2017. Since December 31 2017, the RJ Plan has been confirmed by the RJ Court and our management has 
been making the necessary efforts to implement and monitor the RJ Plan based on the understanding that our financial statements were 
prepared with a going concern assumption. 

We incurred net losses in 2017, 2016, and 2015. We have a substantial level of indebtedness and have experienced a decline in 

consolidated revenues. Our commencement of the RJ Proceedings constituted an event of default of our debt and other obligations. 
These conditions result in material uncertainty that gives rise to substantial doubt about our ability to continue as a going concern within 
one year subsequent to December 31, 2017. We believe that our ability to continue as a going concern is contingent upon our ability to 
implement the RJ Plan, to maintain existing customer, vendor and other relationships and to maintain sufficient liquidity throughout the 
RJ Proceedings, among other factors. 

Our consolidated financial statements do not include any adjustments related to the recoverability and classification of assets or 
the amounts and classification of liabilities or any other adjustments that might be necessary should we be unable to continue as a going 
concern. While operating as under the jurisdiction of the RJ court, we may sell or otherwise dispose of or liquidate assets or settle 
liabilities, subject to the approval of the RJ Court, or as otherwise permitted in the ordinary course of business, for amounts other than 
those reflected in our consolidated financial statements. 

Accounting for RJ Proceedings 

As a result of the RJ Proceedings (which are considered to be similar in all substantive respects to proceedings under Chapter 11 

of the U.S. Bankruptcy Code), we have applied ASC 852 in preparing our consolidated financial statements. ASC 852 requires that 
financial statements separately disclose and distinguish transactions and events that are directly associated with our reorganization from 
transactions and events that are associated with the ongoing operations of our business. Accordingly, expenses, gains, losses and 
provisions for losses that are realized or incurred in the RJ Proceedings have been recorded under the classification “Restructuring 
expenses” in our consolidated statements of operations. In addition, our prepetition obligations that may be impacted by the RJ 
Proceedings based on our assessment of these obligations following the guidance of ASC 852 have been classified on our balance sheet 
as “Liabilities subject to compromise.” Prepetition liabilities subject to compromise are required to be reported at the amount allowed as 
a claim by the RJ Court, regardless of whether they may be settled for lesser amounts and remain subject to future adjustments based on 
negotiated settlements with claimants, actions of the RJ Court or other events. 

In connection with our emergence from the RJ Proceedings, we may be required to adopt fresh start accounting, upon which our 
assets and liabilities will be recorded at their fair value. The fair values of our assets and liabilities as of that date may differ materially 
from the recorded values of its assets and liabilities as reflected in our historical consolidated financial statements. In addition, our 
adoption of fresh start accounting may materially affect our results of operations following the fresh start reporting dates as we may 
have a new basis in our assets and liabilities. Consequently, our financial statements following our adoption of fresh start accounting 
may not be comparable with our financial statements prior to that date and the our historical financial statements may not be reliable 
indicators of our financial condition and results of operations for any period after we adopt fresh start accounting. We concluded that we 
are not required to adopt fresh start accounting as of December 31, 2017 and we are in the process of evaluating the potential impact of 
fresh start accounting on our consolidated financial statements in future periods.

Restatement of 2015 Financial Statements 

The RJ Proceedings prompted us to perform a detailed analysis on the completeness and the accuracy of the judicial deposits and 

accounting balances of the other assets of the RJ Debtors. As a result, we identified weaknesses in some of our operational and financial 
reporting controls and procedures. For more information with respect to the identified material weaknesses in Oi’s internal control over 
financial reporting and the steps that Oi has undertaken to remediate these material weaknesses, see “Item 15. Controls and 
Procedures.” 

Additionally, we determined the need to restate previously issued financial statements and related disclosures to correct errors. 
Accordingly, we are restating our consolidated financial statements for the year ended December 31, 2015. Restatement adjustments 
attributable to fiscal year 2014 and previous fiscal years are reflected as a net adjustment to retained earnings as of January 1, 2015. 

The errors detected and corrected in our financial statements related to our judicial deposits, our provisions for contingencies, 

intragroup balances, tax credits and estimates of revenue from services rendered and not yet billed to customers, as described below. 

As part of our negotiations of our RJ Plan, we obtained information from creditors that were also the depositaries of certain of our 
judicial deposits that was more recent and more detailed than the information with respect to these judicial deposits that was previously 
available to us. In addition, we were able to use new IT tools to collect updated information from website of various courts related to 
lawsuits for which we had made judicial deposits due to the increased use of digitalization processes by these courts. Finally the 
suspension of court claims against us during the pendency of our RJ proceedings resulted in a lower number of new lawsuits against us 
and prevented our posting of new judicial deposits. 

Based on the information available to us, we reviewed some of our processes and controls related to judicial deposits. As a result 
of this review, we identified the errors related to (1) judicial deposits that were recognized in our balance sheet but were withdrawn in 
previous years by the plaintiff following unfavorable court decisions, and (2) the calculation of the statistical provision for civil and 
labor contingencies.

As of January 1, 2015, we wrote off R$3,133 million of judicial deposits already withdrawn and increased our provision for 

contingencies by R$493 million. As a result of the increase in provision for contingencies, the write-off of judicial deposits and the 
correction of the corresponding inflation adjustments on the written off judicial deposits, our restated net loss during 2015 increased by 
R$1,163 million compared to our net loss previously reported. 

In connection with the preparation of our creditors list as part of the RJ proceedings, we performed procedures to obtain 

supporting documentation, which resulted in our collecting information necessary to reconcile intragroup balances. Errors discovered in 
the reconciliation of these intragroup balances led us to recognize additional accounts payable of R$172 million as of January 1, 2015 
and to write off accounts receivable of R$167 million as of January 1, 2015, in each case related to those intragroup balances. As a 
result of the increase in accounts payable and the write-off of accounts receivable, our restated net loss during 2015 decreased by 
R$59 million compared to our net loss previously reported. 

In connection with our internal control over financial reporting, we concluded that we had recorded balances related to direct and 

indirect tax credits that have expired or for which we do not have adequate supporting documentation to claim a refund from tax 
authorities. As of January 1, 2015, we wrote off R$199 million of unrecoverable tax credits previously recognized under taxes, and 
R$52 million of unrecoverable tax credits previously recognized under other assets. 

We estimate revenue from services provided and not yet billed to customers using the available information provided by our 

operating systems. In connection with our internal control over financial reporting, we identified that the most recent operational 
information available as of January 1, 2015 was not used by us to estimate the revenue from our services rendered and not yet billed to 
customers as of that date. As a result, we wrote off R$191 million of provision for estimated unbilled revenue as of January 1, 2015.

Business Segments and Presentation of Segment Financial Data 

We use operating segment information for decision-making. We have identified only one operating segment that corresponds to 

the telecommunications business in Brazil. 

The Telecommunications in Brazil segment includes our telecommunications business in Brazil, In addition to our 

telecommunications business in Brazil, we conduct other businesses that individually or in aggregate do not meet any of the quantitative 
indicators that would require their disclosure as reportable business segments. These businesses are conducted primarily by Companhia 
Santomense de Telecomunicações, Listas Telefónicas de Moçambique, ELTA – Empresa de Listas Telefónicas de Angola, and Timor 
Telecom, which provide fixed and mobile telecommunications services and publish telephone directories in Africa and Asia, and which 
have been consolidated in our financial statements since May 2014. 

Within our Telecommunications in Brazil segment, our management assesses revenue generation based on customer segmentation 

into the following categories: 

•

•

•

Residential Services, focused on the sale of fixed telephony services, including voice services, data communication services 
(broadband), and Pay-TV; 

Personal Mobility Services, focused on the sale of mobile telephony services to postpaid (subscription) and prepaid 
customers that include voice services and data communication services; and 

B2B Services, which includes corporate solutions offered to our small, medium-sized, and large corporate customers, 
including voice services and corporate data solutions and wholesale interconnection and traffic transportation services to 
other telecommunications providers. 

Critical Accounting Policies and Estimates 

Our critical accounting policies and estimates are described in note 2 to our consolidated financial statements included in this 

annual report. In preparing our consolidated financial statements in conformity with U.S. GAAP, our management uses estimates and 
assumptions based on historical experience and other factors, including expected future events, which we consider reasonable and 
relevant. Critical accounting policies are those that are important to the portrayal of our consolidated financial position and results of 
operations and require management’s subjective and complex judgments, estimates and assumptions. The application of these critical 
accounting policies frequently requires judgments made by management regarding the effects of matters that are inherently uncertain 
with respect to the outcomes of transactions and the carrying value of our assets and liabilities. Our actual results of operations and 
financial position may differ from those set forth in our consolidated financial statements, if our actual experience differs from 
management’s assumptions and estimates. In order to provide an understanding of our critical accounting policies, including some of 
the variables and assumptions underlying the estimates, and the sensitivity of those assumptions and estimates to different parameters 
and conditions, we set forth below a discussion of our critical accounting policies relating to: 

•

•

•

•

•

•

•

•

•

revenue recognition and trade receivables; 

depreciation of property, plant and equipment; 

allowances for doubtful accounts; 

fair value of available-for-sale investments; 

deferred income taxes and social contribution; 

impairment of long-lived assets; 

defined postretirement benefit plans; 

contingencies; and 

estimate of expected amount of the allowed claims in the RJ Proceedings.

Revenue Recognition and Trade Receivables 

Our revenues correspond primarily to the amount of the payments received or receivable from sales of services in the regular 

course of our activities and our subsidiaries’ activities. 

Service revenue is recognized when services are provided. Local and long distance calls are charged based on time measurement 

according to the legislation in effect. The services charged based on monthly fixed amounts are calculated and recorded on a straight-
line basis. Prepaid services are recognized as unearned revenues and recognized in revenue as these services are used by customers. 

Revenue from sales of handsets and accessories is recognized when these items are delivered and accepted by the customers. 

Discounts on services provided and sales of cell phones and accessories are taken into consideration in the recognition of the related 
revenue. Revenues involving transactions with multiple elements are identified in relation to each one of their components, and the 
recognition criteria are applied on an individual basis. Revenue is not recognized when there is significant uncertainty as to its 
realization. 

Our revenue is a material component of our results of operations. Management’s determination of price, collectability and the 
rights to receive certain revenues for the use of our network are based on judgments regarding the nature of the fee charged for services 
rendered, the price for certain services delivered and the collectability of those revenues. Should changes in conditions cause 
management to conclude that these criteria are not met for certain transactions, the amount of accounts receivable could be adversely 
affected. In addition, for certain categories of revenue we rely upon revenue recognition measurement guidelines set by ANATEL. 

We consider revenue recognition to be a critical accounting policy, because of the uncertainties caused by different factors such as 

the complex information technology required, high volume of transactions, fraud and piracy, accounting regulations, management’s 
determination of collectability and uncertainties regarding our right to receive certain revenues (mainly revenues for use of our 
network). Significant changes in these factors could cause us to fail to recognize revenues or to recognize revenues that we may not be 
able to realize in the future, despite our internal controls and procedures. We have not identified any significant need to change our 
revenue recognition policy. 

Depreciation of Property, Plant and Equipment 

We depreciate property, plant and equipment using the straight-line method at rates we judge compatible with the useful lives of 

the underlying assets. The depreciation rates of our most significant assets are presented in note 13 to our consolidated financial 
statements included in this annual report. The useful lives of assets in certain categories may vary based on whether they are used 
primarily to provide fixed-line or mobile services. We review the estimated useful lives of the assets taking into consideration technical 
obsolescence and a valuation by outside experts. 

Given the complex nature of our property, plant and equipment, the estimates of useful lives require considerable judgment and 

are inherently uncertain, due to rapidly changing technology and industry practices, which could cause early obsolescence of our 
property, plant and equipment. If we materially change our assumptions of useful lives and if external market conditions require us to 
determine the possible obsolescence of our property, plant and equipment, our depreciation expense, obsolescence write-off and 
consequently net book value of our property, plant and equipment could be materially different. 

Allowance for Doubtful Accounts 

Our allowance for doubtful accounts is established in order to recognize probable losses on accounts receivable and takes into 

account limitations we impose to restrict the provision of services to customers with past-due accounts and actions we take to collect 
delinquent accounts. The allowance for doubtful accounts estimate is recognized in an amount considered sufficient to cover possible 
losses on the realization of these receivables. The allowance for doubtful accounts estimate is prepared based on historic default rates. 
For additional information regarding our allowance for doubtful accounts, see note 8 to our consolidated financial statements included 
in this annual report. 

We have entered into agreements with certain customers to collect past-due accounts receivable, including agreements allowing 
customers to settle their delinquent accounts in installments. The amounts that we actually fail to collect in respect of these accounts 
may differ from the amount of the allowance established, and additional allowance may be required.

Fair Value of Available-for-Sale Investments 

Our investments in Unitel, including our investment in its declared and unpaid dividends, and CVT are classified as 

available-for-sale investments and have been valued at fair value according to the operating assets used as basis in the valuation of these 
investments at the time of our May 2014 capital increase. Unrealized holding gains and losses, net of the related tax effect, on 
available-for-sale investments are excluded from earnings and are reported as a separate component of accumulated other 
comprehensive income until realized. 

The fair value of the available-for-sale investments is estimated based on the internal valuation made, including cash flows 

forecasts for a five-year period, the choice of a growth rate to extrapolate the cash flows projections, and definition of appropriate 
discount rates and foreign exchange rates consistent with the reality of each country where the businesses are located. In addition to the 
financial and business assumptions referred to above, we also take into consideration the fair value measurement of cash investments, 
qualitative assumptions, including the impacts of developments in the lawsuits filed against third parties, and the opinion of the legal 
counsel on the outcome of these lawsuits. With regard to the impairment test of dividends, we use financial assumptions on the discount 
rate in time and the foreign exchange rate, and use qualitative assumptions based on the opinion of the legal counsel on the outcome of 
filed against Unitel for the nonpayment of dividends and interest. We monitor and periodically update the key assumptions and critical 
estimates used to calculate fair value. 

During 2017 and 2016, we recorded losses on available-for-sale financial assets of US$39 million and US$242 million, 
respectively, resulting from the revision of the recoverable amount of dividends receivable from Unitel, the fair value of the cash 
investment in Unitel and exchange rate losses related to the depreciation of the Kwanza against the U.S. dollar and the real. 

Our estimates of future cash flows from our available-for-sale investments may not necessarily be indicative of the amounts that 

could be obtained in the current market. The use of different assumptions to measure the fair value of available-for-sale investments 
could have a material effect on the amounts obtained and not necessarily be indicative of the cash amounts that we would receive on the 
disposal of an available-for-sale investment. 

Deferred Income Taxes and Social Contribution 

Income taxes in Brazil are calculated and paid on a legal entity basis, and there are no consolidated tax returns. Accordingly, we 

only recognize deferred tax assets, related to tax loss carryforwards and temporary differences, if it is likely that they will be realized on 
a legal entity basis. 

We recognize and settle taxes on income based on the results of operations determined in accordance with the Brazilian Corporate 

Law, taking into consideration the provisions of Brazilian tax law, which are materially different from the amounts calculated for U.S. 
GAAP purposes. Under U.S. GAAP, we recognize deferred tax assets and liabilities for temporary differences between the carrying 
amounts and the taxable bases of the assets and liabilities, and tax loss carryforwards are recorded in assets or liabilities, as applicable. 
We recognize the effect of income tax positions only if those positions are more likely than not of being sustained. Recognized income 
tax positions are measured at the largest amount that is greater than 50 percent likely of being realized. Changes in recognition or 
measurement are reflected in the period in which the change in judgment occurs. 

We regularly test deferred tax assets for impairment and recognize a provision for impairment losses when it is probable that these 

assets may not be realized, based on the history of taxable income, the projection of future taxable income, and the time estimated for 
the reversal of existing temporary differences. These projections require the use of estimates and assumptions. In order to project future 
taxable income, we need to estimate future taxable revenues and deductible expenses, which are subject to a variety of external and 
internal factors, such as economic trends, industry trends and interest rates, changes in business strategies, and changes in the type of 
services and products sold by our company. The use of different estimates and assumptions could result in the recognition of a provision 
for impairment losses for the entire or a significant portion of the deferred tax assets.

Impairment of Long-Lived Assets 

Long-lived assets include assets that do not have indefinite lives, such as property, plant, and equipment, and purchased intangible 
assets subject to amortization. These assets are reviewed for impairment whenever events or changes in circumstances indicate that the 
carrying amount of an asset may not be recoverable. If circumstances require a long-lived asset or asset group be tested for possible 
impairment, we first compare the undiscounted cash flows expected to be generated by that asset or asset group to its carrying amount. 
If the carrying amount of the long-lived asset or asset group is not recoverable on an undiscounted cash flow basis, an impairment is 
recognized to the extent that the carrying amount exceeds its fair value. Fair value is determined through various valuation techniques 
including discounted cash flow models, quoted market values and third-party independent appraisals, as deemed necessary. 

We have not recorded any impairment of our long-lived assets during the three years ended December 31, 2017. 

Defined Postretirement Benefit Plans 

We sponsor certain defined postretirement benefit plans for our employees. We record liabilities for defined postretirement 

benefits plan based on actuarial valuations which are calculated based on assumptions and estimates regarding discount rates, 
investment returns, inflation rates for future periods, mortality indices and projected employment levels relating to postretirement 
benefit liabilities. The accuracy of these assumptions and estimates will determine whether we have created sufficient reserves for the 
costs of accumulated defined postretirement benefits plans, and the amount we are required to disburse each year to fund postretirement 
benefits plans. These assumptions and estimates are subject to significant fluctuations due to different external and internal factors, such 
as economic trends, social indicators, our capacity to create new jobs and our ability to retain our employees. All of these assumptions 
are reviewed at the end of each reporting period. If these assumptions and estimates are not accurate, we may be required to revise our 
reserves for defined postretirement benefits, which could materially impact our results of operations. 

Contingencies 

Liabilities for loss contingencies arising from claims, assessment, litigation, fines and penalties are recorded when it is probable 
that the liability has been incurred and the amount can be reasonably estimated, based on the opinion of management and its in-house 
and outside legal counsel. The amounts are recognized based on the cost of the expected outcome of ongoing lawsuits. 

We classify our risk of loss in legal proceedings as remote, possible or probable. Provisions recorded in our consolidated financial 

statements in connection with these proceedings reflect reasonably estimated losses at the relevant date as determined by our 
management after consultation with our general counsel and the outside legal counsel. As discussed in note 18 to our consolidated 
financial statements included in this annual report, we record as a liability our estimate of the costs of resolution of such claims, when 
we consider our losses probable. We continually evaluate the provisions based on changes in relevant facts, circumstances and events, 
such as judicial decisions, that may impact the estimates, which could have a material impact on our results of operations and 
shareholders’ equity. While management believes that the current provision is adequate, it is possible that our assumptions used to 
estimate the provision and, therefore, our estimates of loss in respect of any given contingency will change in the future based on 
changes in the relevant situation. This may therefore result in changes in future provisioning for legal claims. For more information 
regarding material pending claims against our company, see “Item 8. Financial Information—Legal Proceedings” and note 18 to our 
consolidated financial statements included in this annual report. 

Estimate of Expected Amount of the Allowed Claims in the RJ Proceedings 

Our estimate of the expected amount of the allowed claims in the RJ Proceedings is a significant estimate. Future actions and 
decisions by the RJ Court may differ significantly from our own estimate, potentially having material future effects on our financial 
statements, particularly on liabilities subject to compromise. Furthermore, these liabilities are reported as the amounts expected to be 
allowed by the RJ Court, even if they may be settled for lesser amounts. There may be significant differences between the settled 
amount and the expected amount of the allowed claim.

Principal Factors Affecting Our Financial Condition and Results of Operations 

Effects of the RJ Proceedings and Our Financial Restructuring 

In June 2016, as a result of several factors affecting our liquidity, we anticipated that we would no longer be able to comply with 
our payment obligations under our loans and financing transactions and we concluded that filing of a request for judicial reorganization 
in Brazil would be the most appropriate course of action (1) to preserve the continuity of our offering of quality services to our 
customers, within the rules and commitments undertaken with ANATEL, (2) to preserve the value of our company, (3) to maintain the 
continuity of our operations and corporate activities in an organized manner that protects the interests of our company, customers, 
shareholders and other stakeholders, and (4) to protect our cash and cash equivalents. 

Our liquidity crisis was resulted principally from: 

•

•

•

•

•

•

the deterioration of the Brazilian economy, which suffered low or negative GDP growth for several years and increased 
levels of unemployment, with negative effects on (1) our ability to retract and retain customers, and corresponding negative 
effects on our net operating revenue, and (2) due to increases in Brazilian interest rates and the depreciation of the real, 
increases in our financing expenses; 

the increasingly marginal (or in some instances, negative) returns that we achieved through network expansion designed to 
meet the universalization requirements imposed on our company as a fixed line concessionaire under the General Plan of 
Universalization Goals, which require us to make large capital expenditures in certain areas of Brazil that are remote, have 
low demographic density and have a low-income population, without the corresponding ability to recoup these capital 
expenditures through the rates that we charge customers in these areas or elsewhere; 

the change in consumption patterns of Brazilian consumers of telecommunication services as a result of the increasing 
attractiveness of mobile telecommunications, particularly following the global introduction of the “smart phone,” which has 
led to continuous sequential declines in the number of subscribers to our fixed-line services, with corresponding negative 
effects on our net operating revenue; 

the requirement under Brazilian law that we make judicial deposits in connection with our defense of labor, tax, and civil 
lawsuits and regulatory claims brought against our company, which resulted in a significant amount of our liquid assets 
being diverted into judicial deposits, with the result that these assets were not available for us to use for our capital 
expenditure and debt service requirements; 

the imposition of large administrative fines and penalties, including interest on unpaid charges and late fees, by ANATEL, 
which resulted in a significant amount of our liquid assets being diverted to pay these charges or into judicial deposits as we 
defend against these regulatory claims, with the result that these assets were not available for us to use for our capital 
expenditure and debt service requirements; 

the increases in our debt service requirements as we relied on funds obtained from financing transactions in the Brazilian and 
international markets to expand our data communications network and to implement projects to meet ANATEL’s regulatory 
requirements market. 

On June 20, 2016, Oi, together with the other RJ debtors, filed a joint voluntary petition for judicial reorganization pursuant to the 

Brazilian Bankruptcy Law with the RJ Court, pursuant an urgent measure approved by our board of directors. For more information 
regarding the RJ Proceedings, see “Item 4. Information on the Company—Our Recent History and Development—Our Judicial 
Reorganization Proceedings.” 

Our net operating revenue has been negatively affected by the ongoing RJ Proceedings primarily as a result of the impact of these 

proceedings on our ability to attract new corporate customers for our B2B business as these potential customers have been wary of 
entering into long-term service contracts with us during the pendency of these proceedings. We do not believe that the ongoing RJ 
Proceedings have had a direct impact on our net revenue from other services. However, the factors affecting our net operating revenue 
that led to our liquidity crisis persist. 

As a result of the RJ Proceedings, we have realized gains and losses and made provisions for losses that are realized or incurred in 
the RJ Proceedings which have been recorded in as restructuring expenses in our consolidated statements of operations. Reorganization 
items, net were R$2,372 million during 2017 and R$9,006 million during 2016. The principal restructuring expenses that we have 
recorded relate to (1) increases in the amounts of our contingent liabilities to reflect the differences between the carrying amount of 
these contingent liabilities prior to the commencement of the RJ Proceedings and the amounts recognized by the RJ Court, and (2) fees 
and expenses of professional advisors who are assisting us with the RJ Proceedings.

As a result of the commencement of the RJ Proceedings, our loans and financings were classified as liabilities subject to 

compromise and as of the date of the commencement of the RJ Proceedings, we ceased recording interest expenses and foreign 
exchange gains and losses on these loans and financings as part of our financial expenses, net. In addition, in connection with our 
deteriorating financial condition and the commencement of the RJ Proceedings, we reversed our derivative financial instruments during 
the second and third quarters of 2016. 

On December 19 and 20, 2017, the GCM was held to consider approval of the most recently filed judicial reorganization plan. The 
GCM concluded on December 20, 2017 following the approval of the RJ Plan reflecting amendments to the judicial reorganization plan 
presented at the GCM as negotiated during the course of the GCM. 

On January 8, 2018, the RJ Court entered the Brazilian Confirmation Order, ratifying and confirming the RJ Plan, according to its 
terms, but modifying certain provisions of the RJ Plan. The Brazilian Confirmation Order was published in Official Gazette of the State 
of Rio de Janeiro on February 5, 2018, the Brazilian Confirmation Date. 

The Brazilian Confirmation Order, according to its terms, is binding on all parties as long as its effects are not stayed. By 
operation of the RJ Plan and the Brazilian Confirmation Order (provided that no stay or appeal of the Brazilian Confirmation Order 
results in a change of the Brazilian Confirmation Date), the unsecured claims against the RJ Debtors have been novated and discharged 
under Brazilian law and holders of such claims are entitled only to receive the recoveries set forth in the RJ Plan in exchange for their 
claims in accordance with the terms and conditions of the RJ Plan. For more information regarding the recoveries which the creditors 
under our liabilities subject to compromise are entitled to receive under the RJ Plan, see “—Liabilities Subject to Compromise.” 

Following the implementation of the RJ Plan, we expect that the obligations recorded as liabilities subject to compromise will be 

substantially reduced and the recoveries delivered with respect to those obligations to be reflected on our balance sheet under the 
original classifications for the related liabilities or as shareholders’ equity, as applicable. In particular, we expect that our obligations for 
loans and financings will be substantially reduced as described under “—Liabilities Subject to Compromise—Loans and 
Financings—Fixed-Rate Notes.” We also expect that we will record interest expenses and foreign exchange gains and losses on the 
loans and financings recorded as recoveries for our liabilities subject to compromise as part of our financial expenses, net. 

In connection with our emergence from the RJ Proceedings, we may be required to adopt fresh start accounting, upon which our 
assets and liabilities will be recorded at their fair value. The fair values of our assets and liabilities as of that date may differ materially 
from the recorded values of its assets and liabilities as reflected in our historical consolidated financial statements. In addition, our 
adoption of fresh start accounting may materially affect our results of operations following the fresh start reporting dates as we may 
have a new basis in our assets and liabilities. Consequently, our financial statements following our adoption of fresh start accounting 
may not be comparable with our financial statements prior to that date and the our historical financial statements may not be reliable 
indicators of our financial condition and results of operations for any period after we adopt fresh start accounting. We concluded that we 
are not required to adopt fresh start accounting as of December 31, 2017 and we are in the process of evaluating the potential impact of 
fresh start accounting on our consolidated financial statements in future periods. 

Effects of Disposal of Portuguese Business of PT Portugal 

On June 2, 2015, we sold all of the share capital of PT Portugal to Altice Portugal for a purchase price equal to the enterprise value 

of PT Portugal of €6,900 million, subject to adjustments based on the financial debt, cash and working capital of PT Portugal on the 
closing date, plus an additional earn-out amount of €500 million in the event that the consolidated revenues of PT Portugal and its 
subsidiaries (as of the closing date) for any single year between the year ending December 31, 2015 and the year ending December 31, 
2019 is equal to or exceeds €2,750 million. PT Portugal provides a broad range of telecommunications services in Portugal. 

In connection with the closing, Altice Portugal disbursed €5,789 million, of which €869 million was utilized by PT Portugal to 
prepay outstanding indebtedness in that amount, and €4,920 million were paid to our company in cash. We used a portion of the net 
cash proceeds of the PT Portugal Disposition for the prepayment and repayment at maturity of indebtedness of our company. 

In anticipation of the PT Portugal Disposition, PT Portugal transferred PTIF to Oi. As a result of the completion of the PT 
Portugal Disposition, the indebtedness of PTIF was reclassified as indebtedness of our company. In addition, in connection with the PT 
Portugal Disposition, PTIF assumed all obligations under PT Portugal’s outstanding 6.25% Notes due 2016.

In addition, PT Portugal transferred to Oi all of the outstanding share capital of PT Participações, SGPS, S.A., or PT Participações, 

which holds: 

•

•

our 75% interest in Africatel Holding B.V., or Africatel, which holds our interests in telecommunications companies in 
Africa, including telecommunications companies in Angola, Cape Verde, Namibia, and São Tomé and Principe; and 

our interests in TPT, which provides telecommunications, multimedia and IT services in Timor Leste. 

As a result of our decision to sell PT Portugal, the revenue and expenses of PT Portugal for the year ended December 31, 2015 are 

presented in our income statement as discontinued operations. We recorded loss from discontinued operations for 2015 of 
R$867 million, consisting of comprehensive income transferred to our income statement of R$226 million, principally consisting of the 
cumulative foreign exchange differences related to PT Portugal, and a loss on the sale of PT Portugal and divestiture related expenses of 
R$625 million. 

Our R$625 million loss in connection with the sale of PT Portugal consisted of (1) the derecognized investment cost that includes 
goodwill arising on the business combination between our company and PT Portugal and selling expenses totaling R$1,308 million, and 
(2) the R$683 million revenue related to cash proceeds received directly by our company. 

Effects of Investments in Africatel 

At the time of our acquisition of PT Portugal, PT Portugal held indirectly 75% of the outstanding share capital of Africatel which 

held 25% of the outstanding share capital of Unitel. Our management considers this a non-controlling stake in Unitel which does not 
grant our company significant influence over the financial, operating and strategic policies of Unitel since we do not elect enough 
members of the board of directors of Unitel to allow us to be involved in the decision-making process of these policies, including 
decisions on dividend and other distributions, material business relations, appointment of officers or managers, or the provision of key 
technical information. Accordingly, upon the acquisition of PT Portugal, we recognized this investment as an available-for-sale 
financial asset recognized at fair value. The fair value of the investment in Unitel of R$4,089 million was determined based on the 
valuation report prepared by Banco Santander on the valuation of Pharol’s operating assets that was used as the basis for the valuation 
of PT Portugal as part of the Oi capital increase using a series of estimates and assumptions, including the cash flows projections for a 
four-year period, the choice of a growth rate to extrapolate the cash flows projections, and definition of appropriate discount rates. 

On September 16, 2014, our board of directors authorized our management to take the necessary measures to market our shares in 
Africatel. As a result, as of December 31, 2017 and 2016, we recorded the assets and liabilities of Africatel, including its investment in 
Unitel and the accounts receivable relating to declared and unpaid dividends of Unitel, as held-for sale, although we do not record 
Africatel as discontinued operations in our income statement due to the immateriality of the effects of Africatel on our results of 
operations. Due to the many risks involved in the ownership of these interests, particularly our interest in Unitel, we cannot predict 
when the sale of these assets may be completed. 

During 2015, we recognized a loss of R$408 million resulting from the revision of the fair value of the investment in Unitel as a 

result of our updating the main assumptions and material estimates used in the fair value measurement of our investment in Unitel, 
taking into consideration in this assessment possible impacts of actual events related to the investment, notably the lawsuits filed against 
Unitel and its shareholders in 2015. 

During 2017 and 2016, we recorded losses of US$39 million and US$242 million, respectively, resulting from the revision of the 
recoverable amount of dividends receivable from Unitel, the fair value of the cash investment in Unitel and exchange rate losses related 
to the depreciation of the Kwanza against the U.S. dollar and the real. 

Rate of Growth of Brazil’s Gross Domestic Product and Demand for Telecommunications Services 

As a Brazilian company with substantially all of our operations in Brazil, we are affected by economic conditions in Brazil. 

Brazilian GDP grew by an estimated 1.0% in 2017, declined by an estimated 3.5% in 2016 and declined by 3.8% in 2015. The 
substantial and prolonged deterioration of economic conditions in Brazil since the second quarter of 2014 have had a material adverse 
effect on the number of subscribers to our services and the volume of usage of our services by our subscribers and, as a result, our net 
operating revenue.

Based on information available from ANATEL, the number of fixed lines in service in Brazil increased from 39.4 million as of 

December 31, 2007 to 40.8 million as of December 31, 2017, and the number of mobile subscribers in Brazil increased from 
121.0 million as of December 31, 2007 to 236.5 million as of December 31, 2017. Although the demand for telecommunications 
services has increased substantially during the past ten years, the tastes and preferences of Brazilian consumers of these services have 
shifted. 

During the three-year period ended December 31, 2017, the number of mobile subscribers in Brazil has declined at an average rate 

of 5.6% per year, while the number of fixed lines in service in Brazil during the three-year period ended December 31, 2017 has 
declined at an average rate of 3.2% per year. During the three-year period ended December 31, 2017, the number of our mobile 
subscribers (including customers in our Personal Mobility Services and B2B Services) has decreased at an average rate of 8.5% per year 
to 39.0 million at December 31, 2017 from 50.9 million at December 31, 2014, while the number of our fixed lines in service (including 
customers in our Residential Services and B2B Services) has declined by an average rate of 6.6% per year to 12.9 million at 
December 31, 2017 from 15.8 million at December 31, 2014. 

Demand for Our Residential Services 

Because the number of our customers terminating their residential services has exceeded new activations between December 31, 

2014 and December 31, 2017, the number of our residential fixed lines in service declined by 20.3% to 9.2 million at December 31, 
2017 from 11.6 million at December 31, 2014. We have focused on offering more and higher-value added services to new and existing 
customers by combining upselling and cross selling initiatives, thereby increasing the ARPU of our Residential Services business. We 
believe that through our sales of bundles consisting of more than one service, we improve customer profitability and enhance loyalty, 
while also increasing ARPU and minimizing churn rates. Primarily as a result of these initiatives, the ARPU of our residential services 
grew by 3.9% to R$79.6 during 2017 from R$76.6 during 2016, which was a 5.5% increase from R$72.6 during 2015. We believe that 
our focus on the sale of bundled services is the principal reason for the increase in the percentage of our customers that subscribe to 
more than one of our residential services to 58.9% as of December 31, 2017 from 56.2% as of December 31, 2016 and 53.4% as of 
December 31, 2015. 

We are required under ANATEL regulations and our concession contracts to offer a basic service plan to our residential customers 

that permits 200 minutes of usage of our fixed-line network to make local calls. We also offer alternative residential plans that include 
significantly larger numbers of minutes or unlimited minutes and charge higher monthly fees for these plans. Over the past three years, 
the percentage of our customers selecting these alternative plans has grown significantly. Subscribers to our alternative residential 
plans, including our bundled service plans, represented 85.4% of our residential customers as of December 31, 2017 as compared to 
85.5% as of December 31, 2016 and 86.4% of as of December 31, 2015. We believe that our alternative residential plans contribute to a 
net increase in our residential services revenue as many subscribers of our alternative residential plans do not use their full monthly 
allocations of local minutes. 

We have sought to combat the general trend in the Brazilian telecommunications industry of substitution of mobile services in 

place of local fixed-line services by offering a variety of bundled plans that include mobile services, broadband services and Oi TV
subscriptions to our fixed-line customers. In addition, we have been focusing on structural network investments, including the 
introduction of VDSL technology, in order to offer service plans that include higher broadband speeds. As of December 31, 2017: 

•

•

•

35.4% of our residential customers subscribed for bundled service packages, an increase from the 29.1% of our residential 
customers that subscribed for bundled service packages as of December 31, 2016, which was an increase from the 26.3% of 
our residential customers that subscribed for bundled service packages as of December 31, 2015; 

55.8% of our residential customers subscribed for broadband services (whether separately or as part of a bundled service 
plan), an increase from the 52.2% of subscribers as of December 31, 2016, which was an increase from the 48.6% of 
subscribers as of December 31, 2015; and 

16.2% of our residential customers subscribed for Pay TV services (whether separately or as part of a bundled service plan), 
an increase from the 13.0% of subscribers as of December 31, 2016, which was an increase from the 11.0% of subscribers as 
of December 31, 2015. 

In addition, demand for our residential services was negatively affected by a decision of the Brazilian Supreme Court that we must 

pay ICMS tax on customer subscriptions that do not include allowances and our subsequent inclusion of this tax in customers’ bills in 
the first half of 2017.

Demand for Our Personal Mobility Services 

Our customer base for mobility services (including customers in our Personal Mobility Services and B2B Services) has declined 

by 23.5% to 39.0 million at December 31, 2017 from 50.9 million at December 31, 2014. We believe that the primary reason for the 
decline in our Personal Mobility customer base is the reduction in the total number of mobile accesses in Brazil, reflecting the trend to 
consolidate mobile use into a single SIM card, following the launch of all-net plans in response to the successive reductions of the MTR 
tariffs, and the structural market migration from voice to data in response to the offering of more robust data packages. Additionally, we 
have implemented a more intensive policy of disconnecting inactive users to reduce regulatory fees that we must make for each active 
account. Finally, we believe that the number of our prepaid accounts has been significantly reduced as a result of the increase in Brazil’s 
unemployment rate as our net additions of prepaid subscribers is closely correlated to movements in the unemployment rate. During 
2017 and 2016, the average monthly churn rate of our Personal Mobility Services business was 4.1% and 4.4% per month, respectively. 

The market for mobile services is extremely competitive in each of the regions that we serve. As a result, (1) we incur selling 
expenses in connection with marketing and sales efforts designed to retain existing mobile customers and attract new mobile customers, 
and (2) from time to time the discounts that we offer in connection with our promotional activities lead to charges against our gross 
operating revenue from mobile services. Competitive pressures have required us to introduce service plans under which we offer 
unlimited voice calls tied to service offerings priced in relation to the amount of data usage offered. 

Our Oi Livre service offering, which includes a range of all-net voice minutes for calls within Brazil and data allowances for flat 

fees, has had a strong performance since its release in late 2015. As of December 31, 2017 and 2016, Oi Livre had 19.6 million and 
14.8 million subscribers, respectively, corresponding to 65.5% and 44.7%, respectively, of our total pre-paid base. 

Demand for Our B2B Services 

The number of RGUs of our B2B Services has declined by 10.7% to 6.5 million as of December 31, 2017 from 7.3 million as of 

December 31, 2014. We believe that the primary reasons for the decline in our B2B Services customer base are (1) the declining 
macroeconomic conditions in Brazil, which has caused many of our SME customers to downsize or cease operations, (2) contractions in 
the fiscal strength of many of our governmental customers, which has caused them to reduce the scope of their telecommunications 
expenditures, and (3) market perceptions of our company during our RJ proceedings which has made it difficult for us to enter into new 
agreements with corporate customers. Our corporate customers, while better able to survive the current economic instability, often 
respond by reducing their economic activity and their spending for telecommunications products and services. In addition, provided that 
our B2B Services customers also purchase the core fixed-line and mobile services offered to our Residential and Personal Mobility 
Services customers, demand for our B2B Services is subject to some of the same conditions that affect our Residential and Personal 
Mobility Services, including reductions in interconnection tariffs, which have led to more robust mobile package offerings and driven 
the traffic migration trend of fixed-to-mobile substitution. 

Effects of Our Absorption of Network Maintenance Service Operations and Adoption of New Customer Care Model 

We have introduced programs beginning in 2015 to control costs related to network maintenance services and third-party services 

by (1) absorbing operation of several network maintenance service operations and providing these services ourselves, and 
(2) implementing a new customer care quality model through which we have improved our method of allocation of call center traffic to 
promote a greater level of customer service and digitized some of our customer interactions with respect to processing order for new 
services, troubleshooting service issues and dispatching maintenance personnel. 

Through our subsidiary Serede, we absorbed operations of our network maintenance service operations of our contractor in Rio de 

Janeiro in October 2015, our network maintenance service operations of our contractor in the South region of Brazil in May 2016 and 
our network maintenance service operations of our contractor in the North and Northeast regions of Brazil in June 2016. As a result, 
75% of the members of our technical field staff are our employees and are directly managed by our company compared to 20% prior to 
the absorption of these operations. We have revised the focus of our network maintenance service operations to concentrate on 
preventive network maintenance the reduce the number of repairs, in turn reducing the volume of network interventions and increasing 
field force productivity, thus freeing capacity to increase our focus on preventive maintenance. This virtuous cycle improves field 
operations efficiency and reduces costs in terms of both the number of technicians and the volume of materials applied.

As a result, our network maintenance services expense has declined to R$1,252 million during 2017 from R$1,540 million during 
2016 and R$1,902 million during 2015, the effects of which have been partially offset by increased personnel expenses relating to these 
services. In addition to reducing costs, we believe that this initiative has been principally responsible for (1) a reduction of the number 
of repairs by 15.4% during 2017 and 8.7% during 2016, and (2) an increase in productivity of our field staff (as measured by the 
number of field activities carried out divided by the total number of technicians involved) by 15.0% during 2017 and 14.0% during 
2016. Finally, we believe that this initiative has been principally responsible for (1) the reduction in the average time for installation of 
new service by 11.8% during 2017 and 58.2% during 2016, (2) the reduction in the average waiting time for resolution of a customer 
service issue by 9.3% during 2017 and 31.3% during 2016, and (3) a reduction of complaints to ANATEL by 23.0% during 2017 and 
10.0% during 2016. 

During 2016, we implemented a new customer care quality model in which, among other things, we allocated service call traffic 

among our call center service providers based on proven service quality. We believe that this traffic allocation model has stimulated 
better quality in the provision of these services while permitting us to reduce call center costs and achieve higher levels of customer 
satisfaction. The implementation of this allocation model resulted in an 8.9% decline in call center costs during 2017, and we believe 
that this allocation model was principally responsible for a 22.8% decline in the volume of repeated calls during 2017. 

Effects of Adjustments to Our Interconnection Rates 

Telecommunications services rates are subject to comprehensive regulation by ANATEL. In particular, interconnection rates for 
fixed-line and mobile services in the Brazilian telecommunications industry have been subject to comprehensive reductions in recent 
years. 

In July 2014, ANATEL approved rules under which interconnection rates charged by our company for the use of our fixed-line 

and mobile networks would be reduced over a period of years until they were set at rates based on a long-run incremental cost 
methodology. For example, the rates we may charge to terminate calls on our mobile networks (MTR rates) in Regions I, II and III 
declined by 47.1%, 47.7% and 39.2%, respectively, in each of February 2016 and 2017, and they will decline by the same percentages 
in February 2019. In each of February 2017 and 2018, our TU-RL rates in Regions I and II declined by 20.9% and 22.8%, respectively, 
our TU-RIU1 rates in Regions I and II declined by 52.8% and 45.1%, respectively, and our TU-RIU2 rates declined by 57.3% and 
49.9%, respectively, and we expect that these rates will decline by the same percentages in 2019. 

These rate reductions have been a primary reason for the decline in our mobile interconnection revenue to R$500 million during 

2017, from R$627 million during 2016 and R$889 million during 2015, and the decline in our fixed-line interconnection revenue to 
R$71 million during 2017, from R$113 million during 2016 and R$316 million during 2015. However, these rate reductions have also 
led to a substantial reduction of our interconnection costs, which have declined to R$778 million during 2017, from R$1,173 million 
during 2016 and R$1,809 million during 2015. 

As a result of the substantial reductions in our interconnection costs, and in keeping with our strategy of simplifying our portfolios 

to enhance our customers’ experience, since 2015 we have been offering fixed-line and mobile plans that allow all-net calls for a flat 
fee. 

Effects of Claims by ANATEL that Our Company Has Not Fully Complied with Our Quality of Service and Other Obligations 

As a fixed-line service provider, we must comply with the provisions of the General Plan on Quality Goals. As a public regime 

service provider, we must comply with the network expansion and modernization obligations under the General Plan on Universal 
Service Goals and our concession agreements. Our personal mobile services authorizations set forth certain network expansion 
obligations and targets and impose obligations on us to meet quality of service standards. In addition, we must comply with regulations 
of general applicability promulgated by ANATEL, which generally relate to quality of service measures. 

If we fail to meet quality goals established by ANATEL under the General Plan on Quality Goals, fail to meet the network 
expansion and modernization targets established by ANATEL under the General Plan on Universal Service Goals and our concession 
agreements, fail to comply with our obligations under our personal mobile services authorizations or fail to comply with our obligations 
under other ANATEL regulations, we may be subject to warnings, fines, intervention by ANATEL, temporary suspensions of service or 
cancellation of our concessions and authorizations.

On an almost weekly basis, we receive inquiries from ANATEL requiring information from us on our compliance with the various 
service obligations imposed on us by our concession agreements. If we are unable to respond satisfactorily to those inquiries or comply 
with our service obligations under our concession agreements, ANATEL may commence administrative proceedings in connection with 
such noncompliance. We have received numerous notices of commencement of administrative proceedings from ANATEL, mostly due 
to our inability to achieve certain targets established in the General Plan on Quality Goals and the General Plan on Universal Service 
Goals. 

At the time that ANATEL notifies us it believes that we have failed to comply with our obligations, we evaluate the claim and, 

based on our assessment of the probability of loss relating to that claim, may establish a provision. We vigorously contest a substantial 
number of the assessments made against us. As a result of the commencement of the RJ Proceedings, our contingencies related to 
claims of ANATEL were reclassified liabilities subject to compromise and were measure as required by ASC 852. As of December 31, 
2017 our prepetition liabilities subject to compromise included R$9,334 million related with claims of ANATEL. By operation of the 
RJ Plan and the Brazilian Confirmation Order (provided that no stay or appeal of the Brazilian Confirmation Order results in a change 
of the Brazilian Confirmation Date), the claim for these contingent obligations has been novated and discharged under Brazilian law 
and ANATEL is entitled only to receive the recovery set forth in the RJ Plan in exchange for these contingent claims in accordance with 
the terms and conditions of the RJ Plan. For more information regarding the recoveries to which ANATEL is entitled under the RJ Plan, 
see “—Liabilities Subject to Compromise—Civil Contingencies—ANATEL.” 

Effects of Inflation 

After several years of relatively modest inflation in Brazil, inflation rates increased substantially during 2015 to annual rates of 

10.7% as measured by the IGP-DI and the IBGE. Inflation rates subsided during 2016 and 2017, reaching 7.2% and (0.4), respectively, 
as measured by the IGP-DI, and 6.3% and 3.0%, respectively as measured by the IBGE. Because substantially all of our cost of services 
and operating expenses are incurred in reais in Brazil, an increase in inflation has the effect of increasing our operating expenses and 
reducing our margins. Although we have taken significant measures to control and reduce operating expenses during 2017 and 2016, 
the benefits of these measures were reduced during 2016 as a result of the countervailing impact of Brazilian inflation. Although our 
regulated rates are subject to annual adjustment based on the rate of inflation as measured by the IST, the majority of our revenue is 
generated from services delivered at rates that are not regulated or that are provided at a discount to the regulated rates as a result of 
competitive pressures in the market. As a result, we may not be able to pass our increased operating costs and expenses resulting from 
inflationary pressures through to our customers as incurred in the form of higher tariffs for our services. 

A significant portion of our real-denominated loans and financings classified as liabilities subject to compromise bear contractual 

interest at the TJLP or the CDI rate, which are partially adjusted for inflation, and the ICPA rate, an inflation index. As a result of the 
commencement of the RJ Proceedings, we ceased recording interest expenses on these loans and financings. By operation of the RJ 
Plan and the Brazilian Confirmation Order (provided that no stay or appeal of the Brazilian Confirmation Order results in a change of 
the Brazilian Confirmation Date), these loans and loans and financings have been novated and discharged under Brazilian law and 
creditors under these loans and financings are entitled only to receive the recoveries set forth in the RJ Plan in exchange for their claims 
in accordance with the terms and conditions of the RJ Plan. For more information regarding the recoveries to which creditors under our 
loans and financings are entitled under the RJ Plan, see “—Liabilities Subject to Compromise—Loans and Financing.” 

Following the implementation of the RJ Plan, we expect that recoveries of creditors under our debentures, unsecured lines of 
credit and lessors under the lease contracts of Oi and Telemar relating to real property owned by Copart 4 and Copart 5 will accrue 
interest based on the CDI rate. As a result, following the implementation of the RJ Plan, inflation will increase our interest expenses and 
debt service obligations with respect to these recoveries. 

Effects of Fluctuations in Exchange Rates between the Real and the U.S. Dollar 

Substantially all of our cost of services and operating expenses in Brazil are incurred in reais. As a result, the appreciation or 

depreciation of the real against the U.S. dollar does not have a material effect on our operating margins. However, the costs of a 
substantial portion of the network equipment that we purchase for our capital expenditure projects are denominated in U.S. dollars or 
are U.S. dollar-linked. This network equipment is recorded on our balance sheet at its cost in reais based on the applicable exchange 
rate on the date the transfer of ownership, risks and rewards related to the purchased equipment occurs. As a result, depreciation of the 
real against the U.S. dollar results in this network equipment being more costly in reais and leads to increased depreciation expenses. 
Conversely, appreciation of the real against the U.S. dollar results in this network equipment being less costly in reais and leads to 
reduced depreciation expenses.

As of December 31, 2017 and 2016, our loans and financing classified as liabilities subject to compromise denominated in euros 

and U.S. dollars and represented 39.9% and 34.6%, respectively, of our loans and financing classified as liabilities subject to 
compromise. As a result of the commencement of the RJ Proceedings, we ceased recording exchange rate gains and losses with respect 
to these loans and financings. By operation of the RJ Plan and the Brazilian Confirmation Order (provided that no stay or appeal of the 
Brazilian Confirmation Order results in a change of the Brazilian Confirmation Date), these loans and loans and financings have been 
novated and discharged under Brazilian law and creditors under these loans and financings are entitled only to receive the recoveries set 
forth in the RJ Plan in exchange for their claims in accordance with the terms and conditions of the RJ Plan. For more information 
regarding the recoveries to which creditors under our loans and financings are entitled under the RJ Plan, see “—Liabilities Subject to 
Compromise—Loans and Financing.” 

Following the implementation of the RJ Plan, we expect that our obligations under (1) our New Notes that will be issued to 

holders of bonds issued by Oi, Oi Coop and PTIF that are entitled to receive the Qualified Recovery described under “—Liabilities 
Subject to Compromise—Loans and Financing—Fixed Rate Notes,” (2) participations under the Non-Qualified Credit Agreement that 
will be available to holders of bonds issued by Oi, Oi Coop and PTIF that are entitled to receive the Non-Qualified Recovery described 
under “—Liabilities Subject to Compromise—Loans and Financing—Fixed Rate Notes,” (3) recoveries of creditors under our export 
credit agreements, and (4) recoveries under our bonds issued by Oi, Oi Coop and PTIF to holders of our U.S. dollar-denominated bonds 
issued by Oi and Oi Coop that are not entitled to receive the Qualified Recovery or the Non-Qualified Recovery, will be denominated in 
U.S. dollars and will accrue interest at fixed-rates in U.S. dollars. 

As a result, when the real appreciates against the U.S. dollar: 

•

•

•

the interest costs on our indebtedness denominated in U.S. dollars is expected to decline in reais, which will positively 
affects our results of operations in reais; 

the amount of our indebtedness denominated in U.S. dollars is expected to decline in reais, and our total liabilities and debt 
service obligations in reais is expected to decline; and 

our financial expense, net is expected to decline as a result of foreign exchange gains that we record. 

A depreciation of the real against the U.S. dollar is expected to have the converse effects. 

Effect of Level of Indebtedness and Interest Rates 

As of December 31, 2017 and 2016, our loans and financing classified as liabilities subject to compromise was R$49,130 million. 
The level of our indebtedness was a significant factor in our decision to file a request for judicial reorganization in Brazil in June 2016. 

Borrowing and financing costs of our continuing operations consist of interest on borrowings payable to third parties, inflation and 

exchange losses on third-party borrowings and gains and losses on derivative financial instruments as set forth in note 6 to our 
consolidated financial statements included in this annual report. During 2016 and 2015, we recorded borrowing and financing costs of 
our continuing operations of R$1,171 million and R$4,905 million, respectively. 

As a result of the commencement of the RJ Proceedings, we ceased recording borrowing and financing costs of our continuing 
operations with respect to our loans and financings. By operation of the RJ Plan and the Brazilian Confirmation Order (provided that no 
stay or appeal of the Brazilian Confirmation Order results in a change of the Brazilian Confirmation Date), these loans and loans and 
financings have been novated and discharged under Brazilian law and creditors under these loans and financings are entitled only to 
receive the recoveries set forth in the RJ Plan in exchange for their claims in accordance with the terms and conditions of the RJ Plan. 
For more information regarding the recoveries to which creditors under our loans and financings are entitled under the RJ Plan, see 
“—Liabilities Subject to Compromise—Loans and Financing.” 

Following the implementation of the RJ Plan, we expect that the obligations recorded as liabilities subject to compromise will be 

substantially reduced and the recoveries delivered with respect to those obligations to be reflected on our balance sheet under the 
original classifications for the related liabilities or as shareholders’ equity, as applicable. In particular, we expect that our obligations for 
loans and financings will be substantially reduced. We also expect that we will record interest expenses and foreign exchange gains and 
losses on the loans and financings recorded as recoveries for our liabilities subject to compromise as part of our financial expenses, net.

debentures, unsecured lines of credit and lessors under the lease contracts of Oi and Telemar relating to real property owned by Copart 
4 and Copart 5 will accrue interest based on the CDI rate. As a result, following the implementation of the RJ Plan, increases in the CDI 
rate will increase our interest expenses and debt service obligations with respect to these recoveries. 

In addition, the RJ Plan permits us to seek to raise up to R$2.5 billion in the capital markets and seek to borrow up to R$2 billion 

under new export credit facilities, as described under “—Liquidity and Capital Resources.” This debt may accrue interest at floating 
rates in foreign currencies. Accordingly, we may incur interest expenses and foreign exchange gains and losses in connection with this 
new debt. Increases in interest rates will increase our interest expenses and debt service obligations with respect to this indebtedness. 

Seasonality 

Our primary business operations do not have material seasonal operations, other than our sales of handsets and accessories in our 
Personal Mobility business which tends to increase during the fourth quarter of each year as compared to the other three fiscal quarters 
related to significant increases of volume during the year-end holiday shopping season. 

Recent Developments 

Confirmation of RJ Plan 

On January 8, 2018, the RJ Court entered the Brazilian Confirmation Order, ratifying and confirming the RJ Plan, according to its 

terms, but modifying certain provisions of the RJ Plan. The Brazilian Confirmation Order was published in the Official Gazette of the 
State of Rio de Janeiro on February 5, 2018, the Brazilian Confirmation Date. 

The Brazilian Confirmation Order, according to its terms, is binding on all parties as long as its effects are not stayed. By 
operation of the RJ Plan and the Brazilian Confirmation Order (provided that no stay or appeal of the Brazilian Confirmation Order 
results in a change of the Brazilian Confirmation Date), the unsecured claims against the RJ Debtors have been novated and discharged 
under Brazilian law and holders of such claims are entitled only to receive the recoveries set forth in the RJ Plan in exchange for their 
claims in accordance with the terms and conditions of the RJ Plan. 

Election of Recoveries under the RJ Plan 

Under the RJ Plan, certain groups of creditors were entitled to make elections with respect to the form of the recovery that they 

were entitled to receive. The period to make these elections commenced on the Brazilian Confirmation Date and was scheduled to 
expire on February 26, 2018. On February 26, 2018, the RJ Court extended the election deadline applicable to beneficial holders of 
bonds issued by Oi, Oi Coop and PTIF until March 8, 2018. For more information with respect to the recoveries available to holders of 
bonds issues by Oi, Oi Coop and PTIF, see “—Liabilities Subject to Compromise—Loans and Financing—Fixed-Rate Notes.” 

Voting for Dutch Composition Plans 

On April 10, 2018, PTIF deposited a draft of the PTIF Composition Plan with the Dutch Court and Oi Coop deposited a draft of 

the Oi Coop Composition Plan with the Dutch Court. The PTIF Composition Plan and the Oi Coop Composition Plan each provide for 
the restructuring of the claims against PTIF and Oi Coop on substantially the same terms and conditions as the RJ Plan. 

On April 10, 2018, Oi commenced a solicitation of votes of the holders of the seven series of bonds issued by PTIF in favor of a 
proposal to (1) approve extraordinary resolutions (a) releasing of Oi’s guarantee of the relevant series of bonds, and (b) instructing the 
trustee of such series of bonds to vote in favor of the PTIF Composition Plan and to provide a direction to the PTIF Bankruptcy Trustee 
in respect of its vote on behalf of PTIF on the Oi Coop Composition Plan; and (2) approve the PTIF Composition Plan.

Under the documents governing the bonds issued by PTIF, these actions may be taken at a meeting of holders of the applicable 
series of bonds at which at least two-thirds of the principal amount of the applicable bonds are represented in person or by proxy. In the 
event that quorum is not obtained at any such meeting, these actions may be taken at a meeting of holders of the applicable series of 
bonds at a second meeting called for the purpose at which at least one-third of the principal amount of the applicable bonds are 
represented in person or by proxy. In either case, the proposed extraordinary resolution may be passed by the vote of not less than 75% 
of the principal amount of the applicable bonds represented in the meeting. 

The voting deadline under this voting solicitation was April 27, 2018 for one of these series of bonds and April 30, 2018 for the 
other six series of bonds. At meetings of each of these series of bonds held on May 2, 2018, quorum was not achieved for any of these 
series of bonds. As a result, on May 3, 2018, Oi published notices to convene adjourned meetings of each of these series of bonds on 
May 17, 2018 and establishing a new voting deadline of May 14, 2018. Based on the votes received as of the second voting deadline, 
we believe that each of the extraordinary resolutions will be passed and that each of these series of bonds will vote to approve the PTIF 
Composition Plan. 

A meeting of the creditors of PTIF has been scheduled on June 1, 2018 at which the creditors of PTIF will consider the PTIF 

Composition Plan and the votes solicited by Oi will be presented to the PTIF Bankruptcy Trustee. Based on the results of the voting 
solicitation, we expect that the creditors of PTIF will approve the PTIF Composition Plan, however we cannot assure you that 
procedural matters will not be raised at this meeting of creditors that will result in the failure of the creditors to approve the PTIF 
Composition Plan. 

If the PTIF Composition Plan is approved at the meeting of the creditors of PTIF, we expect that the Dutch Court will schedule a 
hearing on prior to June 15, 2018 to rule on the homologation of the PTIF Composition Plan. Although we expect that the Dutch Court 
will homologate the PTIF Composition Plan at that hearing, we cannot assure you that procedural matters will not be raised at this 
hearing that will result in the failure of the Dutch Court to homologate the PTIF Composition Plan. If the PTIF Composition Plan is 
homologated, the PTIF Composition Plan will be given full force and effect in each member state of the European Union. 

On April 10, 2018, Oi commenced a solicitation of votes of the holders of the two series of bonds issued by Oi Coop in favor of 

the Oi Composition Plan. The voting deadline under this voting solicitation was May 15, 2018. As of the voting deadline, the tabulation 
is in the process of being finalized. 

A meeting of the creditors of Oi Coop has been scheduled on June 1, 2018 at which the creditors of Oi Coop will consider the Oi 

Coop Composition Plan and the votes solicited by Oi will be presented to the Oi Coop Bankruptcy Trustee and the PTIF Bankruptcy 
Trustee is expected to vote the claim represented by an intercompany loan made by PTIF to Oi Coop. Based on the preliminary results 
of the voting solicitation, if the extraordinary resolutions of the PTIF bonds are passed by all series of PTIF bonds instructing the PTIF 
Bankruptcy Trustee to vote the claim represented by an intercompany loan made by PTIF to Oi Coop in favor of the Oi Coop 
Composition Plan, we expect that the creditors of Oi Coop will approve the Oi Coop Composition Plan, however we cannot assure you 
that procedural matters will not be raised at this meeting of creditors that will result in the failure of the creditors to approve the Oi 
Coop Composition Plan. If the extraordinary resolutions of the PTIF bonds are not passed by all series of PTIF bonds, we cannot assure 
you as to how the PTIF Bankruptcy Trustee will vote the claim represented by an intercompany loan made by PTIF to Oi Coop, and if 
the PTIF Bankruptcy Trustee vote this claim against approval of the Oi Coop Composition Plan, we expect the Oi Coop Composition 
Plan will not be approved. 

If the Oi Coop Composition Plan is approved at the meeting of the creditors of Oi Coop, we expect that the Dutch Court will 
schedule a hearing on prior to June 15, 2018 to rule on the homologation of the Oi Coop Composition Plan. Although we expect that the 
Dutch Court will homologate the Oi Coop Composition Plan at that hearing, we cannot assure you that procedural matters will not be 
raised at this hearing that will result in the failure of the Dutch Court to homologate the Oi Coop Composition Plan. If the Oi Coop 
Composition Plan is homologated, the Oi Coop Composition Plan will be given full force and effect in each member state of the 
European Union.

Filing of Chapter 15 Motion 

On April 17, 2018, the foreign representative for the Chapter 15 Debtors filed a motion with the U.S. Bankruptcy Court seeking an 
order of that court granting, among other things, full force and effect to the RJ Plan and the Brazilian Confirmation Order in the United 
States. The deadline for objections to the proposed order set by the U.S. Bankruptcy Court was May 11, 2018. As of that date, Pharol, 
Bratel B.V. and Bratel S.à r.l. filed an objection to that motion in which they argued that the motion should be denied without prejudice 
or deferred consideration until after certain appellate proceedings, arbitration and mediation have been concluded in Brazil. 
Additionally, The Bank of New York Mellon filed a limited objection requesting to revise certain portions of the proposed order, but 
did not object to the motion itself. The U.S. Bankruptcy Court has scheduled a hearing on the objections to the proposed order on 
May 29, 2018. If the U.S. Bankruptcy Court grants the requested order, the claims with respect to our bonds issued under indentures 
governed by New York law will be novated and discharged under New York law and the holders of these bonds will be entitled only to 
receive the recovery set forth in the RJ Plan in exchange for the claims represented by these bonds.

(23.0)

(72.1) 
(8.5) 

Net operating revenue of our Telecommunications in Brazil segment declined by 6.4% during 2017, principally due to a 14.7% 

decline in net operating revenue from B2B services, and to a lesser extent, a 2.2% decline in net operating revenue from residential 
services, and a 2.6% decline in net operating revenue from personal mobility services. In addition, net operating revenue of our other 
operations declined by 72.1%, principally as a result of our disposition of our interest in MTC in January 2017. 

Net Operating Revenue from Residential Customer Services 

Net operating revenue from residential customer services represented 38.5% of our net operating revenue during 2017. Residential 

customer services include fixed telephony services, including voice services, data communication services (broadband), and Pay-TV. 
Net operating revenue from residential services declined by 2.2%, primarily due to (1) the 3.3% decline in the average number of 
residential revenue generating units, or RGUs; (2) the decline in voice traffic, and (3) the reduction in TU-RL and TU-RIU fixed line 
interconnection tariffs and VC fixed-to-mobile tariffs in February 2017. These effects were partially offset by the 3.9% increase in the 
average monthly net residential revenue per user (calculated based on the total revenue for the year divided by the monthly average 
customer base for the year divided by 12) to R$79.6 in 2017 from R$76.6 in 2016, primarily due to an increase in broadband and 
Pay-TV revenues. 

Net Operating Revenue from Residential Fixed-Line Services. Net operating revenue from residential fixed-line services declined 

by 9.5%, primarily due to a 7.2% decline in the average number of residential fixed lines in service to 9.2 million during 2017 from 
9.9 million during 2016, as a result of (1) the general trend in the Brazilian telecommunications industry to substitute mobile services in 
place of local fixed-line services, and (2) the impact of two rate increases during the year. The effects of these factors were partially 
offset by the migration of our fixed-line customer base to convergent service offerings, such as Oi Total, and other plans offering 
unlimited minutes of usage, which generate greater revenue per user. 

Net Operating Revenue from Broadband Services. Net operating revenue from residential broadband services increased by 0.9%, 
primarily as a result of a 1.5% increase in the average net operating revenue per subscriber, primarily as a result of the migration of our 
broadband base to service offerings with higher speed, which generate greater revenue per user. The effects of this migration were 
partially offset by a 0.6% decline in the average number of our residential ADSL subscribers. As of December 31, 2017, our ADSL 
subscribers represented 55.8% of our total residential fixed lines in service and subscribed to plans with an average speed of 8.3 Mbps 
as compared to 52.2% of our total residential fixed lines in service at an average speed of 6.8 Mbps as of December 31, 2016.

Net Operating Revenue from Pay-TV Services. Net operating revenue from residential Pay-TV services increased by 22.9%, 
primarily as a result of a 16.0% increase in the average number of our residential Pay-TV subscribers increased to 1.5 million during 
2017 from 1.3 million during 2016, and a 5.9% increase in the average net operating revenue per subscriber, principally as a result of 
the shift in the our sales mix towards more comprehensive packages of channels. As of December 31, 2017, our Pay-TV subscribers 
represented 16.2% of our total residential fixed lines in service as compared to 13.0% of our total residential fixed lines in service as of 
December 31, 2016. 

Net Operating Revenue from Personal Mobility Services 

Net operating revenue from personal mobility services represented 32.1% of our net operating revenue during 2017. Personal 

mobility services include sales of mobile telephony services to post-paid and pre-paid customers that include voice services and data 
communication services. Net operating revenue from personal mobility services declined by 2.6%, primarily due to (1) a 20.2% decline 
in mobile interconnection revenue, and (2) a 1.2% decline in revenue from mobile telephony services. 

Net Operating Revenue from Mobile Telephony Services. Net operating revenue from mobile telephony services declined by 1.2%, 

primarily due to: 

•

•

a 9.3% decline in the number of mobile customers that subscribe to our prepaid plans to 29.9 million during 2017 from 
33.0 million during 2016, principally as a result of (1) an increase in Brazil’s unemployment rate as our sales net additions of 
prepaid subscribers is closely correlated to movements in the unemployment rate, (2) the migration of prepaid customers in 
Brazil to the use of a single SIM card as operators have increased the offer of “all-net” plans following the successive 
reductions of the MTR tariffs, and (3) our strict disconnection policy for inactive customers, which is designed to reduce fee 
payments that we must make for each active account; and 

a 2.1% decline in the number of mobile customers that subscribe to our postpaid plans to 6.7 million during 2017 from 
6.9 million during 2016. 

The effects of these declines were partially offset by a 7.5% increase in average monthly net revenue per user, primarily as a result of an 
improvement in the profile of our customer base. During 2017, data revenue represented 53.9% of net operating revenue from mobile 
telephony services as compared to 47.2% during 2016. 

Net Operating Revenue from Interconnection to Our Mobile Network. Mobile interconnection revenue declined by 20.2% in 2017, 

primarily as a result of the reduction in MTR interconnection tariffs in February 2017. 

Net Operating Revenue from B2B Services 

Net operating revenue from B2B services represented 27.3% of our net operating revenue during 2017. B2B services include 

corporate solutions offered to our small, medium-sized, large corporate customers, including voice services and corporate data 
solutions, and wholesale customers. Net operating revenue from B2B services declined by 14.7%, primarily as a result of (1) lower 
voice traffic, following the natural market trend, (2) the reduction in MTR interconnection tariffs and VC fixed-to-mobile tariffs in 
February 2017, (3) the slowdown in Brazilian economic activity, with has led to efforts by corporate and government customers to 
reduce costs, including telecommunications services costs, and has led to the downsizing or closing of many of our SME customers, and 
(4) market perceptions of our company during our RJ proceedings which has made it difficult for us to enter into new agreements with 
corporate customers. 

As a result of these factors, we experienced a 1.6% decline in the total number of B2B customers to 6.5 million during 2017 from 

6.6 million during 2016, principally as a result of a 3.2% decline in fixed line customers, partially offset by a 1.1% increase in mobile 
customers.

Operating Expenses 

Under the Brazilian Corporate Law, we are required to segregate cost of sales and services from operating expenses in the 
preparation of our income statement. However, in evaluating and managing our business, we prepare reports in which we review the 
elements included in cost of sales and services and operating expenses classified by nature, as presented in note 5 of our financial 
statements. We believe that this classification improves our ability to understand results and trends in our business and that financial 
analysts and other investors who review our performance rely on this classification in performing their own analysis. Therefore, we 
have presented the discussion below of our operating expenses based on the classification of operating expenses presented in note 5 of 
our financial statements. 

The following table sets forth the components of our operating expenses, as well as the percentage change from the prior year, for 

the years ended December 31, 2017 and 2016.

The effects of these factors were partially offset by our incurrence of R$1,233 million in other operating expenses, net during 2017 
compared to R$227 million during 2016. 

Third-Party Services 

Third-party service costs declined by 2.8% in 2017, primarily as a result of lower call center expenses as a result of our adoption 

of our new customer care model and lower legal advisory and consulting services expenses as a result of a reduction of judicial 
processes. The effects of these factors were partially offset by higher content acquisition costs for our Pay-TV services as a result of the 
16.0% increase in the average number of our residential Pay-TV subscribers, an increase in sales commission expenses as a result of an 
increase in sales of higher value services, and a reduction in energy costs. 

Depreciation and Amortization 

Depreciation and amortization costs declined by 6.8% in 2017, primarily as a result of the growth of increase in the amount of the 

property, plant and equipment that has been fully depreciated. 

Rental and Insurance 

Rental and insurance costs declined by 3.9% in 2017, primarily as a result of (1) an decline in reais of certain rental expenses 
denominated in U.S. dollars as a result of the appreciation of real against U.S. dollar during 2017, particularly expenses relating to our 
agreements with GlobeNet and our lease of capacity on the SES-6 satellite, and (2) the absence of expenses during 2017 relating to 
settlement agreements with other operators we entered into in 2016 related to the leasing of towers and equipment. The effects of these 
factors was partially offset by (1) increased tower and equipment leasing costs, and (2) increased vehicles leasing costs as a result of our 
absorption of network maintenance operations. 

Personnel 

Personnel expenses (including employee benefits and social charges and employee and management profit sharing) declined by 

2.1% in 2017, primarily as a result of (1) headcount reductions that we implemented in May 2016 and in the fourth quarter of 2016, and 
(2) initiatives that that we have implemented to promote greater efficiency and productivity as well as stricter cost controls related in 
personnel expenses. The effects of these factors were partially offset by (1) the increase in the number of our employees as a result of 
our absorption of network service operations in 2016, (2) increases in the compensation of some of our employees as a result of the 
renegotiation of some of our collective bargaining agreements at the end of 2016, (3) increased provisions for variable compensation 
related to the fulfillment of operational, financial and quality goals established for 2017 under some of our collective bargaining s, and 
(4) our implementation of certain strategic projects that have resulted in the insourcing of services that used to be provided by third 
parties in order to improve quality and productivity in some of our critical processes.

Network Maintenance Services 

Network maintenance services costs declined by 18.7% in 2017, primarily as a result of (1) our absorption of network service 
operations in the state of Rio de Janeiro and in the South, North and Northeast regions, as a result of which we no longer incur costs to 
third parties for these services, and our focus on conducting more efficient field operations focused on increased productivity and 
preventive actions. The effects of this factor were partially offset by our insourcing of technical support call center operations in 2017 
and annual readjustments of costs under our contracts.

Interconnection 

Interconnection costs declined by 33.7% in 2017, primarily as a result of the declines in MTR interconnection tariffs and the 

TU-RL and TU-RIU interconnection tariffs that were implemented in February 2017 and February 2016. The effects of these factors 
were partially offset by an increase in off-net mobile traffic volume as a result of our introduction of new mobile plans based on the 
“all-net” model. 

Contingencies 

In 2016, contingencies included R$858 million related to labor contingencies of Rede Conecta. 

Allowance for Doubtful Accounts 

Allowance for doubtful accounts increased by 7.5% in 2017, primarily as a result of an increase in consumer default rates as a 
result of the deterioration Brazilian macroeconomic conditions. During the year ended December 31, 2017, allowance for doubtful 
accounts represented 2.9% of our net operating revenue compared to 2.5% in 2016. 

Advertising and Publicity 

Advertising and publicity expenses declined by 7.9% in 2017, primarily as a result of a decline in the volume of our advertising 

campaigns. 

Handsets and Other Costs 

Handsets and other costs declined by 21.4% in 2017, primarily due to lower handset sales. 

Impairment Losses 

Impairment losses declined by 79.4% in 2017. Impairment losses in 2017 and 2016 consisted of losses on goodwill relating to 

Africatel, which is reported as a held-for-sale asset as a result of our annual impairment testing. 

Taxes and Other Expenses 

Taxes and other expenses declined by 38.3% in 2017, primarily due to a decrease in other tax expenses, due to a decrease in other 

revenues in which other taxes are associated and a decrease in expenses for fines. 

Other Operating Expenses, Net 

Other operating expenses, net increased to R$1,233 million in 2017 from R$227 million in 2016, primarily as a result of the 

effects of non-recurring expenses related to unrecoverable tax, write-off of other assets and other expenses due to reconcile the 
accounting balances as part of the RJ Proceedings. 

Reorganization Items, Net 

As a result of the RJ Proceedings, we have applied ASC 852 in preparing our consolidated financial statements. ASC 852 requires 

that financial statements distinguish transactions and events that are directly associated with the reorganization from the ongoing 
operations of the business. Accordingly, certain expenses, realized gains and losses and provisions for losses that are realized or 
incurred in the RJ Proceedings have been recorded in as restructuring expenses in our consolidated statements of operations.

Reorganization items, net declined by 69.7% to R$2,732 million during 2017 from R$9,006 million during 2016. Reorganization 
items, net during 2017 consisted of (1) a R$1,569 million increase of the amount recorded relating to our contingent liabilities owed to 
ANATEL to the amount allowed for these claims in the RJ Proceedings, which was greater than their carrying amount prior to the 
commencement of the RJ Proceedings (2) a R$1,146 million increase of the amount recorded relating to our contingent liabilities to the 
amount allowed for these claims in the RJ Proceedings, which was greater than their carrying amount prior to the commencement of the 
RJ Proceedings, and (2) fees and expenses of R$370 million of professional advisors who are assisting us with the RJ Proceedings. The 
effects of these expenses were partially offset by our recognition of income from short-term investments of R$713 million, which were 
recognized as reorganization items. 

Reorganization items, net during 2016 consisted of (1) a R$6,604 million increase of the amount recorded relating to our 
contingent liabilities owed to ANATEL to the amount allowed for these claims in the RJ Proceedings, which was greater than their 
carrying amount prior to the commencement of the RJ Proceedings, (2) a R$2,350 million increase of the amount recorded relating to 
our other contingent liabilities to the amount allowed for these claims in the RJ Proceedings, which was greater than their carrying 
amount prior to the commencement of the RJ Proceedings and (2) fees and expenses of R$253 million of professional advisors who are 
assisting us with the RJ Proceedings. The effects of these expenses were partially offset by our recognition of income from short-term 
investments of R$202 million, which were recognized as reorganization items. 

Operating Loss before Financial Expenses, Net, and Taxes 

As a result of the foregoing, the operating loss before financial expenses, net, and taxes of our Telecommunications in Brazil 
segment declined by 70.1%, to R$2,697 million during 2017 from R$9,008 million during 2016. As a percentage of net operating 
revenue, the operating loss before financial expenses, net, and taxes of our Telecommunications in Brazil segment declined to 11.4% 
during 2017 from 35.8% during 2016. 

Operating expenses of our other operations declined by 68.5% to R$303 million during 2017 from R$884 million during 2016, 

principally as a result of our disposition of our interest in MTC in January 2017. The operating loss before financial expenses, net, and 
taxes of our other operations increased by 37.5%, to R$70 million during 2017 from R$51 million during 2016. As a percentage of net 
operating revenue, the operating loss before financial expenses, net, and taxes of our other operations increased to 30.0% during 2017 
from 6.1% during 2016. 

Our consolidated operating loss before financial expenses, net, and taxes declined by 69.5%, to R$2,767 million during 2017 from 

R$9,059 million during 2016. As a percentage of net operating revenue, operating loss before financial expenses, net, and taxes 
declined to 11.6% during 2017 from 34.8% during 2016. 

Financial Expenses, Net 

Financial Income 

Financial income increased by 32.4% to R$1,550 million during 2017 from R$1,171 million during 2016, primarily due to (1) a 
70.7% increase in interest on other assets to R$1,050 million during 2017 from R$615 million during 2016, principally as a result of 
interest on judicial deposits and monetary variation on others assets and (2) our recording no gain on exchange rate differences on 
translating foreign short-term investments during 2017, as part of the recognition as reorganization items, net compared to a 
R$135 million loss during 2016. The effects of these factors was partially offset by (1) our recording no income from short-term 
investments during 2017, as part of the recognition as reorganization items, net compared to income of R$112 million during 2016, and 
(2) a 13.5% decline in other income to R$500 million during 2017 from R$578 million during 2016.

Financial Expenses 

Financial expenses declined by 43.0% to R$3,162 million during 2017 from R$5,546 million during 2016, primarily due to the 

elimination of our borrowing and financing costs in 2017 as a result of the commencement of the RJ Proceedings in June 2016, 
compared to our borrowing and financing costs of R$2,746 million during 2016, the effects of which were partially offset by a 12.9% 
increase in other charges to R$3,162 million during 2017 from R$2,800 million during 2016. 

Other charges increased primarily as a result of (1) a 174.3% increase in interest on other liabilities to R$1,641 million during 

2017 from R$598 million during 2016, principally due to the commencement of our participation in the Tax Recovery Program 
(REFIS) in May 2017, and (2) a 158.6% increase in other expenses to R$450 million during 2017 from R$174 million during 2016. The 
effects of these factors was partially offset by (1) a 75.5% decline in loss on available for sale financial assets to R$267 million during 
2017 from R$1,090 million during 2016, principally as a result of the reduction of the loss recorded based on our revision of the 
recoverable amount of dividends receivable from Unitel, the fair value of the cash investment in Unitel and exchange losses rate related 
to the depreciation of the Kwanza against the U.S. dollar and the real to US$39 million during 2017 from US$242 million during 2016, 
and (2) a 24.6% decline in tax on financial transactions and bank fees to R$512 million during 2017 from R$679 million during 2016, 
principally due to a reduction in these types of expenses as a result of judicial recovery. 

Income Tax and Social Contribution 

The composite corporate statutory income tax and social contribution rate was 34% in each of 2017 and 2016. We recorded an 

income tax and social contribution benefits of R$351 million during 2017 and an income tax and social contribution expenses of 
R$2,245 million during 2016. The effective tax rate applicable to our loss before taxes was 8.0% during 2017 and (16.7)% during 2016. 
The table below sets forth a reconciliation of the composite corporate statutory income tax and social contribution rate to our effective 
tax rate for each of the periods presented.

The effective tax rate applicable to our loss before taxes was 8.0% in 2017, resulting in a tax benefit, primarily as a result of (1) 
the tax effects of valuation allowance and valuation allowance, which resulted in a decline in our tax assets by R$1,135 million, that 
were recognized for the companies that as at December 31, 2017, do not expect to generate sufficient future taxable profits against 
which these tax assets could be offset, which reduced the effective tax rate applicable to our loss before taxes by 25.9%, (effectively 
reducing our tax benefit) and (2) the tax effects of amnesty program which reduced the effective tax rate applicable to our loss before 
taxes by 6.3%. The effects which were partially offset by the tax effects of permanent exclusions, which increased the effective tax rate 
applicable to our loss before taxes by 8.5% (effectively increasing our tax benefit). 

The effective tax rate applicable to our loss before taxes was (16.7)% in 2016, resulting in a tax expense despite our incurring a 

loss before taxes, primarily as a result of (1) the tax effects of valuation allowance, which resulted in a decline in our tax assets by 
R$4,050 million that were recognized for the companies that, as at December 31, 2016, do not expect to generate sufficient future 
taxable profits against which these tax assets could be offset, which reduced the effective tax rate applicable to our loss before taxes by 
30.1% (effectively increasing our tax expense), and (2) the tax effects on permanent additions, primarily as a result of the effects of the 
adjustments of debt obligations due to the filing of the judicial reorganization petitions and based on the RJ Plan, which reduced the 
effective tax rate applicable to our loss before taxes by 21.5% (effectively increasing our tax expense).

Net operating revenue of our Telecommunications in Brazil segment declined by 4.8% during 2016, principally due to (1) a 6.9% 
decline in net operating revenue from personal mobility services, (2) a 4.1% decline in net operating revenue from residential services, 
and (3) a 4.6% decline in net operating revenue from B2B services. Net operating revenue of our other operations declined by 8.7%. 

Net Operating Revenue from Residential Customer Services 

Net operating revenue from residential customer services represented 36.1% of our net operating revenue during 2016. Net 
operating revenue from residential services declined by 4.1%, primarily due to (1) the 9.3% decline in the average number of residential 
RGUs, and (2) the reduction in TU-RL and TU-RIU fixed line interconnection tariffs and VC fixed-to-mobile tariffs in February 2016. 
These effects were partially offset by the 5.5% increase in the average monthly net residential revenue per user (calculated based on the 
total revenue for the year divided by the monthly average customer base for the year divided by 12) to R$76.6 in 2016 from R$72.6 in 
2015, primarily due to the increase in broadband and Pay-TV revenues. 

Net Operating Revenue from Residential Fixed-Line Services. Net operating revenue from residential fixed-line services declined 

by 5.5%, primarily due to a 5.4% decline in the average number of residential fixed lines in service to 9.9 million during 2015 from 
10.5 million during 2015, as a result of the general trend in the Brazilian telecommunications industry to substitute mobile services in 
place of local fixed-line services. The effects of this factor was partially offset by the migration of our fixed-line customer base to 
convergent service offerings, such as Oi Total, which generate greater revenue per user. 

Net Operating Revenue from Broadband Services. Net operating revenue from residential broadband services increased by 6.9%, 
primarily as a result of (1) a 5.3% increase in the average net operating revenue per subscriber, primarily as a result of the migration of 
our broadband base to service offerings with higher speed, which generate greater revenue per use, and (2) a 1.5% increase in the 
average number of our residential ADSL subscribers to 5.2 million during 2016 from 5.1 million during 2015. As of December 31, 
2016, our ADSL subscribers represented 52.2% of our total residential fixed lines in service and subscribed to plans with an average 
speed of 6.9 Mbps as compared to 48.6 % of our total residential fixed lines in service at an average speed of 5.6 Mbps as of 
December 31, 2015. 

Net Operating Revenue from Pay-TV Services. Net operating revenue from residential Pay-TV services increased by 23.6%, 
primarily as a result of a 12.1% increase in the average net operating revenue per subscriber, principally as a result of the shift in the our 
sales mix towards more comprehensive packages of channels, and a 10.4% increase in the average number of our residential Pay-TV 
subscribers to 1.3 million during 2016 from 1.2 million during 2015. As of December 31, 2016, our Pay-TV subscribers represented 
13.7% of our total residential fixed lines in service as compared to 11.0% of our total residential fixed lines in service as of 
December 31, 2015.

Net operating revenue from personal mobility services represented 30.2% of our net operating revenue during 2016. Net operating 

revenue from personal mobility services declined by 6.9%, primarily due to (1) a 29.5% decline in mobile interconnection revenue, 
(2) a 39.9% decline in revenue from sales of handsets and accessories, and (3) a 1.9% decline in revenue from mobile telephony 
services. 

Net Operating Revenue from Mobile Telephony Services. Net operating revenue from mobile telephony services declined by 1.9%, 

primarily due to a 15.5% decline in the number of mobile customers that subscribe to our prepaid plans to 33.0 million during 2016 
from 39.1 million during 2015, principally as a result of (1) the migration of prepaid customers in Brazil to the use of a single SIM card 
as operators have increased the offer of “all-net” plans following the successive reductions of the MTR tariffs, and (2) our strict 
disconnection policy for inactive customers, which is designed to reduce fee payments that we must make for each active account. The 
effects of this decline were partially offset by (1) a 15.9% increase in average monthly net revenue per user, primarily as a result of an 
increase in data revenue, and (2) a 1.2% increase in the number of mobile customers that subscribe to our postpaid plans to 6.9 million 
during 2016 from 6.8 million during 2015, principally as a result of a trend toward the migration from prepaid customers to postpaid 
offers. During 2016, data revenue represented 47.2% of net operating revenue from mobile telephony services as compared to 37.2% 
during 2015. 

Net Operating Revenue from Interconnection to Our Mobile Network. Mobile interconnection revenue declined by 29.5% in 2016, 

primarily as a result of the reduction in MTR interconnection tariffs in February 2016. 

Net Operating Revenue from Sales of Handsets and Accessories. Net operating revenue from sales of handsets and accessories 
(primarily SIM cards) declined by 39.9%, principally as a result of our strategy to outsource handsets sales in order to increase logistical 
efficiency and improve the supply of handsets in our sales channels. 

Net Operating Revenue from B2B Services 

Net operating revenue from B2B services represented 29.3% of our net operating revenue during 2016. Net operating revenue 
from B2B services declined by 4.6%, primarily as a result of (1) the slowdown in Brazilian economic activity, with has led to efforts by 
corporate and government customers to reduce costs, including telecommunications services costs, and has led to the downsizing or 
closing of many of our SME customers, and (2) the reduction in MTR interconnection tariffs and VC fixed-to-mobile tariffs in February 
2016, and (3) market perceptions of our company during our RJ proceedings which has made it difficult for us to enter into new 
agreements with corporate customers. 

As a result of these factors, we experienced a 2.1% decline in the total number of B2B customers to 6.6 million during 2016 from 

6.8 million during 2017, principally as a result of a 4.6% decline in fixed line customers, partially offset by a 3.0% increase in mobile 
customers.

Operating expenses declined by 4.1% in 2016, principally due to: 

•

•

•

•

•

a 42.5%, or R$782 million, increase in contingencies; 

a 35.1%, or R$635 million, decline in interconnection costs; 

a 44.8%, or R$454 million, decline in taxes and other expenses; 

a 61.8%, or R$365 million, decline in impairment losses; and 

a 19.0%, or R$361 million, decline in network maintenance services. 

The effects of these factors were partially offset by: 

•

•

•

a 20.3%, or R$730 million, increase in rental and insurance costs; 

our incurrence of R$227million in other operating expenses, net during 2016 compared to R$218 million in other operating 
income, net during 2015; and 

a 4.9%, or R$133 million, increase in personal expenses. 

Third-Party Services 

Third-party service costs increased by 1.3% in 2016, primarily as a result of an increase in costs under our contract for satellite 
services with Globosat and increased content acquisition costs for our Pay-TV services as a result in the improvement of our Pay-TV 
customer mix. The effects of these factors were partially offset by lower call center expenses as a result of our adoption of our new 
customer care model and a reduction in sales commission expenses as a result of our efforts to optimize our sales channels through the 
increased use of our own channels. 

Depreciation and Amortization 

Depreciation and amortization costs increased by 1.9% in 2016, primarily as a result of the growth of our data and mobile network 
due to our strategy of modernization of the core network focusing on transmission and transport infrastructure, which has increased the 
amount of depreciable property, plant and equipment and amortizable license.

Rental and Insurance 

Rental and insurance costs increased by 20.3% in 2016, primarily as a result of (1) an increase in reais of certain rental expenses 
denominated in U.S. dollars as a result of the depreciation of real against U.S. dollar during 2016, particularly expenses relating to our 
agreements with GlobeNet and our lease of capacity on the SES-6 satellite, (2) the effects of Brazilian inflation on certain of our 
contracts that index our costs to Brazilian inflation indexes, (3) an increase in the quantity of submarine cable capacity that we rent, 
(4) increased vehicles leasing costs as a result of our absorption of network maintenance operations, and (5) our entering into settlement 
agreements with other operators related to the leasing of towers and equipment. 

Personnel 

Personnel expenses (including employee benefits and social charges and employee and management profit sharing) increased by 

4.9% in 2016, primarily as a result of (1) an increase in the number of our employees as a result of our absorption of network service 
operations in the state of Rio de Janeiro and in the South, North and Northeast regions, and (2) increases in the compensation of some of 
our employees as a result of the renegotiation of some of our collective bargaining agreements at the end of 2015. The effects of these 
increases were partially offset by (1) headcount reductions that we implemented in April 2015, May 2016 and in the fourth quarter of 
2016, and (2) reduced provisions for employee profit sharing in 2016. 

Network Maintenance Services 

Network maintenance services costs declined by 19.0% in 2016, primarily as a result of our absorption of network service 
operations in the state of Rio de Janeiro and in the South, North and Northeast regions, as a result of which we no longer incur costs to 
third parties for these services. The effects of this factor were partially offset by annual contractual adjustments under our agreements 
with network maintenance service providers. 

Interconnection 

Interconnection costs declined by 35.1%, primarily as a result of the declines in MTR interconnection tariffs and the TU-RL and 
TU-RIU interconnection tariffs that were implemented in February 2015 and February 2016. The effects of these factors were partially 
offset by an increase in off-net mobile traffic volume as a result of our introduction of new mobile plans based on the “all-net” model. 

Contingencies 

In 2016, contingencies included R$858 million related to labor contingencies of Rede Conecta. In 2015, contingencies included 

R$976 million related to the effect of the increase in provision for contingencies, the write-off of judicial deposits and the correction of 
the corresponding inflation adjustments on the written off judicial deposits, our restated net loss during 2015. 

Allowance for Doubtful Accounts 

Allowance for doubtful accounts declined by 10.8% in 2016, primarily as a result of an improvement in our customers’ payment 

profile, reflecting our focus on sales quality, particularly in the B2B Services revenue segment. During the year ended December 31, 
2016, allowance for doubtful accounts represented 2.5% of our net operating revenue compared to 2.7% in 2015. 

Advertising and Publicity 

Advertising and publicity expenses increased by 10.7% in 2016, primarily as a result of our resumption of commercial activities at 

the end of 2015 with the increased focused on o the launch of our re-branding and marketing campaigns to support Oi Total, Oi Livre, 
Oi Mais and Oi Mais Empresas.

Handsets and Other Costs 

Handsets and other costs remained substantially unchanged in 2016 compared to 2015. 

Impairment Losses 

Impairment losses declined by 61.8% in 2016. Impairment losses in 2016 consisted of the impairment loss on goodwill related to 

Africatel, which is reported as a held-for-sale asset, as a result of our annual impairment testing . Impairment losses in 2015 consisted of 
(1) R$501 million related to goodwill and trademarks for the operations in Brazil due to a significant change in the macroeconomic 
conditions in Brazil, and (2) R$89 million related to loss on goodwill related to our operations in Africa. 

Taxes and Other Expenses 

Taxes and other expenses declined by 44.8% in 2016 primarily due to reducing costs as part of the RJ Proceedings. 

Other Operating Income (Expenses), Net 

Other operating expense, net was R$227 million in 2016 compared to other operating income, net of R$219 million in 2015. The 
principal components of other operating income, net in 2016 include expenses related to write-off of other assets and other expenses of 
R$132 million due to reconcile the accounting balances as part of the RJ Proceedings. The principal components of other operating 
income, net in 2015 include the reversal of a civil contingency amounting to R$325,709 arising from the revision of the calculation 
methodology and R$47,756 in costs relating to terminations of employments contracts in this period. 

The principal components of other operating income, net in 2015 were (1) a R$326 million reversal of a civil contingency arising 
from the revision of the methodology we use to calculate civil contingencies, and (2) R$48 million in costs relating to terminations of 
employees during 2015. 

Reorganization Items, Net 

As a result of the RJ Proceedings, we have applied ASC 852 in preparing our consolidated financial statements. ASC 852 requires 

that financial statements distinguish transactions and events that are directly associated with the reorganization from the ongoing 
operations of the business. Accordingly, certain expenses, realized gains and losses and provisions for losses that are realized or 
incurred in the RJ Proceedings have been recorded in as restructuring expenses in our consolidated statements of operations. 

Reorganization items, net during 2016 consisted of (1) a R$6,600 million increase of the amount recorded relating to our 
contingent liabilities owed to ANATEL to the amount allowed for these claims in the RJ Proceedings, which was greater than their 
carrying amount prior to the commencement of the RJ Proceedings (2) a R$2,350 million increase of the amount recorded relating to 
our other contingent liabilities to the amount allowed for these claims in the RJ Proceedings, which was greater than their carrying 
amount prior to the commencement of the RJ Proceedings, and (3) fees and expenses of R$253 million of professional advisors who are 
assisting us with the RJ Proceedings. The effects of these expenses were partially offset by our recognition of income from short-term 
investments of R$202 million, which were recognized as reorganization items. 

We did not recognize reorganization items, net during 2015. 

Operating Income (Loss) before Financial Income (Expenses) and Taxes 

As a result of the foregoing, the operating loss before financial expenses, net, and taxes of our Telecommunications in Brazil 

segment increased to R$15,794 million during 2016 from R$319 million during 2015. As a percentage of net operating revenue, the 
operating loss before financial expenses, net, and taxes of our Telecommunications in Brazil segment increased to 62.8% during 2016 
from 1.2% during 2015.

Operating expenses of our other operations increased by 38.9% to R$884 million during 2016 from 636 million during 2015, 
principally as a result of exchange rate losses related to the depreciation of the Kwanza against the U.S. dollar and the real. Operating 
loss before financial expenses, net, and taxes of our other operations was R$51 million during 2016 compared to operating income 
before financial expenses, net, and taxes of R$276 million during 2015. As a percentage of net operating revenue, the operating loss 
before financial expenses, net, and taxes of our other operations was 6.1% during 2016 compared to operating income before financial 
expenses, net, and taxes of 30.3% during 2015. 

Our consolidated operating loss before financial expenses, net, and taxes increased to R$9,059 million during 2016 from income 

of R$177 million during 2015. As a percentage of net operating revenue, operating loss before financial expenses, net, and taxes 
increased to 34.8% during 2016 from operating income before financial expenses, net, and taxes to 0.6% during 2015. 

Financial Expenses, Net 

Financial Income 

Financial income declined by 78.2% to R$1,171 million during 2016 from R$5,364 million during 2015, primarily due to (1) our 

recording a R$135 million loss on exchange rate differences on translating foreign short-term investments during 2016 compared to 
gain of R$3,350 million during 2015, principally as a result of the appreciation of the real against the U.S. dollar and the Euro in 2016, 
and (2) decline in other income to R$578 million during 2016 from R$1,010 million during 2015 as a result of the to the gain on 
debenture repayment transactions and US$187.5 million (R$733 million) related with our portion of dividends approved by Unitel. 

Financial Expenses 

Financial expenses declined by 54.1% to R$5,546 million during 2016 from R$12,089 million during 2015, primarily due to (1) 

our a 70.0% decline in borrowing and financing costs to R$2,746 million during 2016 from R$9,162 million during 2015, and (2) a 
24.6% decline in other charges to R$2,800 million during 2016 from R$2,927 million during 2015. 

Borrowing and financing costs declined primarily as a result of our recording a gain on inflation and exchange losses on third-

party borrowings of R$4,580 million during 2016 compared to a loss of R$10,908 million during 2015, primarily as a result of (1) the 
elimination of our borrowing and financing costs in second half as a result of the commencement of the RJ Proceedings in June 2016, 
and (2) the appreciation of the real against the U.S. dollar and the Euro in 2016, and to a lesser extent, a 46.2% decline in interest on 
borrowings payable to third parties to R$2,178 million during 2016 from R$4,050 million during 2015, primarily as a result of (1) the 
elimination of our borrowing and financing costs in second half as a result of the commencement of the RJ Proceedings in June 2016. 
The effects of these factors were partially offset by our recording a R$5,148 million loss on derivatives transactions during 2016 
compared to a gain of R$5,797 million during 2015, primarily as a result of the appreciation of the real against the U.S. dollar and the 
Euro in 2016. 

Other charges declined primarily as a result of (1) a decline on interest on other liabilities to R$598 million during 2016 from 
R$833 million during 2015, principally due to reducing cost as part of the RJ Proceedings, and (2) a 63.5% decline in other expenses to 
R$174 million during 2016 from R$477 million during 2015, principally due to reducing cost as part of the RJ Proceedings, and (3) a 
67.5% decline in inflation adjustment of provisions to R$238 million during 2016 from R$363 million during 2015. The effects of these 
factors was partially offset by a 143.5% increase in loss on available for sale financial assets to R$1,090 million during 2016 from 
R$448 million during 2015, principally as a result of the loss recorded based on our revision of the recoverable amount of dividends 
receivable from Unitel, the fair value of the cash investment in Unitel and exchange losses rate related to the depreciation of the 
Kwanza against the U.S. dollar and the real to US$242 million during 2016 from US$188 million during 2015. 

Income Tax and Social Contribution 

The composite corporate statutory income tax and social contribution rate was 34% in each of 2016 and 2015. We recorded an 

income tax and social contribution expenses of R$2,245 million during 2016 and R$3,380 million during 2015. The effective tax rate 
applicable to our loss before taxes was (11.1)% during 2016 and (51.6)% during 2015. The table below sets forth a reconciliation of the 
composite corporate statutory income tax and social contribution rate to our effective tax rate for each of the periods presented.

The effective tax rate applicable to our loss before taxes was (16.71)% in 2016, resulting in a tax expense despite our incurring a 

loss before taxes, primarily as a result of (1) the tax effects of valuation allowance, which resulted in a decline in our tax assets by 
R$4,050 million that were recognized for the companies that, as at December 31, 2016, do not expect to generate sufficient future 
taxable profits against which these tax assets could be offset, which reduced the effective tax rate applicable to our loss before taxes by 
30.1% (effectively increasing our tax expense), and (2) the tax effects on permanent additions, primarily as a result of the effects of the 
adjustments of debt obligations due to the filing of the judicial reorganization petitions and based on the RJ Plan, which reduced the 
effective tax rate applicable to our loss before taxes by 21.5% (effectively increasing our tax expense). 

The effective tax rate applicable to our loss before taxes was (51.6)% in 2015, resulting in a tax expense despite our incurring a 

loss before taxes, primarily as a result of the tax effects of valuation allowance, which resulted in a decline in our tax assets by 
R$5,171 million, that were recognized for the companies that, as at December 31, 2015, do not expect to generate sufficient future 
taxable profits against which these tax assets could be offset, which reduced the effective tax rate applicable to our loss before taxes by 
79.0% (effectively increasing our tax expense). 

Net Loss from Continuing Operations 

Our net loss from continuing operations declined by 58.0% to R$15,680 million during 2016 from R$10,794 million during 2015. 

As a percentage of net operating revenue, net loss from continuing operations increased to 60.3% during 2016 from 36.3% in 2015. 

Net Loss from Discontinued Operations 

We had no net income or loss from discontinued operations during 2016. 

Net loss from discontinued operations in 2015 of R$867 million consisted of a R$226 million loss related to the cumulative 
foreign exchange differences recognized in other comprehensive income, transferred from equity to net income from discontinued 
operations for the year due to the sale of PT Portugal and expenses of R$625 million of expenses related to the derecognized investment 
cost that includes goodwill arising on the business combination of our company with PT Portugal less selling expenses and cash 
received directly our company. 

Net Income 

As a result of the foregoing, our consolidated net loss increased by 45.3% to R$15,680 million during 2016 from 

R$10,794 million during 2015. As a percentage of net operating revenue, our net loss increased to 60.3% during 2016 from 39.5% 
during 2015.

Liquidity and Capital Resources 

Our principal cash requirements have historically consisted of the following: 

• working capital requirements; 

•

•

•

servicing of our indebtedness; 

capital expenditures related to investments in operations, expansion of our networks and enhancements of the technical 
capabilities and capacity of our networks; and 

dividends on our shares, including in the form of interest attributable to shareholders’ equity. 

As a result of the commencement of the RJ Proceedings in June 2016, we ceased to pay principal and interest on our loans and 

financings subsequent to the date of the commencement of the RJ Proceedings. By operation of the RJ Plan and the Brazilian 
Confirmation Order (provided that no stay or appeal of the Brazilian Confirmation Order results in a change of the Brazilian 
Confirmation Date), our loans and financings have been novated and discharged under Brazilian law and creditors under our loans and 
financings are entitled only to receive the recoveries set forth in the RJ Plan in exchange for their claims in accordance with the terms 
and conditions of the RJ Plan. For more information regarding the recoveries which the creditors under our liabilities subject to 
compromise are entitled to receive under the RJ Plan, see “—Liabilities Subject to Compromise.” 

Under our bylaws, unless our board of directors deems it inconsistent with our financial position, payment of dividends is 
mandatory. Notwithstanding the requirements of our bylaws, under the RJ Plan, we are prohibited from declaring or paying any 
dividend, return on capital, or making any other payment or distribution on (or related to) our shares prior to the sixth anniversary of the 
Brazilian Confirmation Order. 

Our principal sources of liquidity have traditionally consisted of the following: 

•

•

•

cash flows from operating activities; 

short-term and long-term loans; and 

sales of debt securities in domestic and international capital markets. 

As a result of the commencement of our RJ Proceedings in June 2016, our access to short-term and long-term loans and our ability 

to sell debt securities in domestic and international capital markets has been substantially curtailed. 

During 2017 and 2016, our operations generated cash flows of R$4,402 million and R$3,100 million, respectively. We used 
R$6,224 million of our cash to repay loans and financings in 2016 prior to the commencement of the RJ Proceedings. In addition, our 
capital expenditures during 2017 and 2016 were R$4,334 million and R$3,264 million, respectively. We believe that our continued 
program of capital expenditures is necessary in order for us to operate in the competitive environment for telecommunications services 
in Brazil. As our cash flow generated from our operations has not been sufficient to meet the demands of our investing and financing 
activities, our balances of cash and cash equivalents have declined as of December 31, 2016 and 2017. 

As of December 31, 2017 and 2016, our consolidated cash and cash equivalents and cash investments amounted to 

R$6,999 million and R$7,849 million, respectively. As of December 31, 2017 and 2016, we had working capital (consisting of current 
assets less current liabilities, excluding assets held-for-sale and liabilities of assets-held-for-sale) of R$9,284 million and 
R$11,944 million, respectively. 

We expect to use our cash flows from operating activities and our cash and cash equivalents and short-term cash investments to 

fund our capital expenditures and debt service obligations. Following the implementation of the RJ Plan, we expect that the obligations 
recorded as liabilities subject to compromise will be substantially reduced and the recoveries delivered with respect to those obligations 
to be reflected on our balance sheet under the original classifications for the related liabilities or as shareholders’ equity, as applicable. 
In particular, we expect that our obligations for loans and financings will be substantially reduced as described under “—Liabilities 
Subject to Compromise—Loans and Financings—Fixed-Rate Notes.” However, we will have cash interest payment obligations under 
our New Notes which we will be required to fund from our available cash resources.

We anticipate that we will be required to spend approximately R$968 million to meet our short-term contractual obligations and 

commitments during 2018, and an additional approximately R$4,736 million to meet our long-term contractual obligations and 
commitments in 2019 and 2020. 

As part of the RJ Plan, we negotiated the terms of the Commitment Agreement with members of the Ad Hoc Group, the IBC and 

certain other unaffiliated bondholders under which such bondholders agreed to backstop an eventual cash capital increase of R$4 billion 
by our company, which will be commenced following the full implementation of the RJ Plan provided that certain conditions set forth 
in the Commitment Agreement are met. In addition, the RJ Plan permits us to seek to raise up to R$2.5 billion in the capital markets and 
seek to borrow up to R$2 billion under new export credit facilities. In the absence of the funds committed under the Commitment 
Agreement or other funds obtained in the capital markets or under new credit export facilities, we may have insufficient funds to 
implement our capital expenditure program and modernize our infrastructure, which could result in a significant deterioration of our 
ability to generate cash flows from operating activities. 

Our consolidated financial statements as of December 31, 2017 and 2016 and for the years ended December 31, 2017, 2016 and 

2015 have been prepared assuming that we will continue as a going concern. Our management’s assessment of our ability to continue as 
a going concern is discussed in note 1 to our consolidated financial statements included in this annual report. As of December 31, 2017, 
our management had taken relevant steps in the RJ Process, particularly the preparation, presentation and approval of the RJ Plan, 
which allows our viability and continuity, and the approval of the RJ Plan by our creditors on December 20, 2017. Since December 31 
2017, the RJ Plan has been confirmed by the RJ Court and our management has been making the necessary efforts to implement and 
monitor the RJ Plan based on the understanding that our financial statements were prepared with a going concern assumption. 

We believe that our ability to continue as a going concern is contingent upon our ability to implement the RJ Plan, to maintain 

existing customer, vendor and other relationships and to maintain sufficient liquidity throughout the RJ Proceedings, among other 
factors. For a discussion of risks relating to the implementation of the RJ Plan, see “Item 3. Key Information—Risk Factors—Risks 
Relating to Our Financial Restructuring.”

Our primary source of operating funds has historically been cash flow generated from our operations and we have financed our 

investments in property, plant and equipment through the use of bank loans, vendor financing, capital markets and other forms of 
financing. However, during 2015, our operations generated negative cash flows of R$1,054 million we financed our investments in 
property, plant and equipment, net judicial deposits and net debt servicing costs with the net cash proceeds received upon our sale of PT 
Portugal.

Subsequent to 2015, our cash flow generated from our operations has recovered, however our access to new funds to finance our 
investments in property, plant and equipment in the form of bank loans, vendor financing, capital markets and other forms of financing 
has been substantially eliminated following the commencement of our RJ proceedings. During 2016, we used a substantial portion of 
our cash and cash equivalents to pay indebtedness as it matured (whether at maturity or, in certain cases, upon acceleration) prior to the 
commencement of our RJ proceedings. As our cash flow generated from our operations has not been sufficient to meet the demands of 
our investing and financing activities, our balances of cash and cash equivalents have declined as of December 31, 2016 and 2017. 

2017 Cash Flows 

Cash Flows from Operating Activities 

Net cash provided by operating activities was R$4,402 million during 2017 compared to net loss of R$4,028 million during 2017, 

primarily as a result of:

•

•

the effects of our incurrence of non-cash depreciation and amortization expenses of R$5,881 million during 2017; and 

the effects of our incurrence of non-cash provision for reorganization items, net of R$2,371 million during 2017, primarily as 
a result of (1) a R$1,569 million increase of the amount recorded relating to our contingent liabilities owed to ANATEL to 
the amount allowed for these claims in the RJ Proceedings, which was greater than their carrying amount prior to the 
commencement of the RJ Proceedings (2) a R$1,146 million increase of the amount recorded relating to our contingent 
liabilities to the amount allowed for these claims in the RJ Proceedings, which was greater than their carrying amount prior 
to the commencement of the RJ Proceedings, and (3) fees and expenses of R$370 million of professional advisors who are 
assisting us with the RJ Proceedings. 

Cash Flows from Investing Activities 

Net cash used by investing activities was R$4,422 million during 2017. During 2017, investing activities which used cash 
primarily consisted of investments of R$4,344 million in purchases of property, plant and equipment and intangible assets, primarily 
related to the expansion of our data communications network and IT capacity to increase the quality and capacity of our network in 
order to promote more efficient operational performance and improvements in service quality and customer experience. 

Cash Flows from Financing Activities 

Financing activities used net cash of R$692 million during 2017. During 2017, we used cash principally (1) to purchase shares the 

50% of the shares of Rio Alto that we did not own for R$300 million, (2) to make installment payments under the tax refinancing plan 
in the aggregate amount of R$227 million, and (3) to make installment payments relating to our permits and concessions in the 
aggregate amount of R$104 million.

Net cash provided by operating activities was R$3,100 million during 2016 compared to net loss of R$15,680 million during 2016, 

primarily as a result of: 

•

•

•

•

•

the effects of our incurrence of non-cash provision for reorganization items, net of R$9,006 million during 2016, primarily as 
a result of (1) a R$6,600 million increase of the amount recorded relating to our contingent liabilities owed to ANATEL to

to the commencement of the RJ Proceedings, and (2) fees and expenses of R$253 million of professional advisors who are 
assisting us with the RJ Proceedings; 

the effects of our incurrence of non-cash provision for contingencies of R$1,056 million, primarily as a result of an increase 
of the amount recorded relating to our other contingent liabilities; 

the effects of our incurrence of non-cash depreciation and amortization expenses of R$6,311 million during 2016; 

the effects of our incurrence of non-cash deferred income tax expenses of R$1,532 million during 2016, primarily as a result 
of valuation allowance of deferred taxes, net of the increase in deferred tax recognized; and 

the effects of our incurrence of non-cash losses on derivative financial instruments of R$5,150 million during 2016 prior to 
our reversal of our derivative financial instruments during the second and third quarters of 2016, primarily as a result of the 
17.8% appreciation of the real against the U.S. dollar and the 16,7% appreciation of the real against the Euro during the first 
half of 2016. 

The effects of these factors were partially offset by the effects of our incurrence of non-cash gains on financial instruments of 
R$5,343 million during 2016, primarily as a result of the 17.8% appreciation of the real against the U.S. dollar and the 16.7% 
appreciation of the real against the Euro during the first half of 2016. 

Cash Flows from Investing Activities 

During 2016, investing activities of our continuing operations which used cash primarily consisted of (1) investments of 
R$3,264 million in purchases of property, plant and equipment and intangible assets, primarily related to the expansion of our data 
communications network and IT capacity to increase the quality and capacity of our network in order to promote more efficient 
operational performance and improvements in service quality and customer experience, and (2) net judicial deposits (consisting of 
deposits less redemptions) of R$660 million, primarily related to provisions for labor, taxes and civil contingencies. 

Cash Flows from Financing Activities 

During 2016, we used cash principally (1) to repay R$5,845 million principal amount of our outstanding loans and financings, net 

of derivatives financial instruments, consisting primarily of (i) a revolving credit facility in the aggregate amount of US$700 million,

aggregate amount of R$59 million (vi) an aggregate of R$290 million under credit facilities with BNDES, (2) to make installment 
payments relating to our permits and concessions in the aggregate amount of R$205 million, and (3) to make installment payments 
under the tax refinancing plan in the aggregate amount of R$94 million.

We are also subject to contingencies with respect to tax, civil, labor and other claims and have made provisions for accrued 
liability for legal proceedings related to certain tax, civil, labor and other claims of R$1,368 million as of December 31, 2017 and 
R$1,129 million as of December 31, 2016. See “Item 8. Financial Information—Legal Proceedings” and note 18 to our consolidated 
financial statements included in this annual report. 

Prepetition Liabilities Subject to Compromise 

As a result of the RJ Proceedings, we have applied ASC 852 in preparing our consolidated financial statements. ASC 852 requires 
that financial statements separately disclose and distinguish transactions and events that are directly associated with our reorganization 
from the transactions and events that are associated with the ongoing operations of our business. Accordingly, our prepetition 
obligations that may be impacted by the RJ Proceedings based on our assessment of these obligations following the guidance of ASC 
852 have been classified on our balance sheet as “Liabilities subject to compromise.” Prepetition liabilities subject to compromise are 
required to be reported at the amount allowed as a claim by the RJ Court, regardless of whether they may be settled for lesser amounts 
and remain subject to future adjustments based on negotiated settlements with claimants, actions of the RJ Court or other events. The 
following table reflects prepetition liabilities subject to compromise as at December 31, 2016 and 2017:

(1) Total liabilities subjected to compromise is different from the aggregate amount of liabilities stated on the Second Creditors List of R$63,960 million. Under ASC 
852, we are required to use the criteria set forth in Financial Accounting Standards Board Accounting Standards Codification 450 “Contingencies”, or ASC 450, to 
estimate the total amount of allowed claims, including non-liquid claims that were excluded from the Second Creditors List. 

Under the RJ Plan, claims are classified in one of four classes and the treatment of claims is differentiated for each of 

these classes: 

• Class I – labor-related claims; 

• Class II – secured claims; 

• Class III – unsecured claims, statutorily or generally privileged claims, and subordinated claims; and 

• Class IV – claims held by “small companies” under Brazilian law. 

The following discussion briefly describes the material types of claims classified as “Liabilities subject to compromise,” describes 
the classification of those claims under the RJ Plan, the treatment of those claims under the RJ Plan and our expectations with respect to 
the settlement of those claims. 

Loans and Financing 

On a consolidated basis, our Euro-denominated indebtedness was R$19,578 million as of each of December 31, 2017 and 2016, 

our U.S. dollar-denominated indebtedness was R$16,978 million as of December 31, 2017 and 2016, and our real-denominated 
indebtedness was R$12,573 million as of December 31, 2017 and 2016.

Under the instruments governing all of our financial indebtedness, the commencement of the RJ Proceedings on June 20, 2016 
constituted an event of default. As a result of the commencement of the RJ Proceedings, all principal and interest under each of these 
debt instruments was deemed immediately due and payable. As a result of our application of ASC 852 in preparing our consolidated 
financial statements, all of our loans and financings outstanding as of June 20, 2016 have been classified as “Liabilities subject to 
compromise” in our balance sheet as of December 31, 2017 and 2016. 

As a result of the commencement of the RJ Proceedings on June 20, 2016, our financial liabilities are part of the list of payables 

subject to renegotiation, payment of interest and repayment of principal of our loans and financing were suspended from the date of the 
commencement of the RJ proceeding through December 31, 2017, and we have not recorded interest expenses on the balances of these 
financial liabilities during 2017 or 2016. 

Our principal loans and financings consist of: 

•

•

•

•

•

•

credit facilities with BNDES; 

fixed-rate notes issued in the international market; 

credit facilities with international export credit agencies; 

unsecured lines of credit obtained from Brazilian and international financial institutions; 

debentures issued in the Brazilian market; and 

real estate securitization transactions. 

The following discussion briefly describes the claims recognized in the RJ proceedings with respect to our loans and financings 

and the loans and financings under the RJ Plan. 

Credit Facilities with BNDES 

As of December 31, 2017 and 2016, we had a variety of outstanding credit facilities with BNDES. The proceeds of these credit 

facilities have been used for a variety of purposes, including funding our investment plans, funding the expansion of our 
telecommunications plant (voice, data and video), and making operational improvements to meet the targets established in the General 
Plan on Universal Service Goals and the General Plan on Quality Goals in effect at the time of these loans. As of December 31, 2017 
and 2016, all of our debt instruments with BNDES were secured by pledges of certain of our accounts receivable. 

The following table sets forth for certain information with respect to our outstanding credit facilities with BNDES, including the 

aggregate amount of the claims under such credit facilities recognized by the RJ Court.

Under the RJ Plan, the claim of BNDES under these credit facilities was classified as a Class II claim. Under the RJ Plan, creditors 
holding Class II claims will be entitled to receive payment of 100% of the principal amount of their recognized claims in reais, adjusted 
by the interest/inflation adjustment rate. The principal amount of these claims will be paid in 108 monthly installments beginning in the 
73rd month following the Brazilian Confirmation Date, in the amount of 0.33% of the outstanding principal for the first 60 monthly 
installments, 1.67% of the outstanding principal for the next 47 monthly installments and the remainder at maturity on the 15th
anniversary of the Brazilian Confirmation Date. The principal amount of these claims will accrue interest at the TJLP rate plus 
2.946372%per annum from the Brazilian Confirmation Date. Interest will be capitalized to increase the principal balance under these 
claims on an annual basis during the first four years following the Brazilian Confirmation Date, and will be paid monthly in cash 
thereafter through the final maturity.

As a result of payments made to some of the holders of the bonds issued by PTIF that participated in the Small Creditors Program 
in Portugal, the total claims represented by these bonds has been reduced by R$136 million. For more information regarding the Small 
Creditors Program, see “Item 4. Information on the Company—Our Recent History and Development—Our Judicial Reorganization 
Proceedings—Small Creditor Program.” 

Under the RJ Plan, the claims of holders of these bonds were classified as Class III claims. Under the RJ Plan, each Bondholder is 

entitled to receive the Qualified Recovery (as described below), the Non-Qualified Recovery (as described below) or the Default 
Recovery in respect of the claims evidenced by the bonds such Bondholder beneficially holds, which we refer to as Bondholder Credits. 

Under the RJ Plan, Eligible Bondholders were permitted to make an election as to the form of recovery that they wish to receive. 

All other Bondholders are only entitled to receive the Default Recovery. 

Under the RJ Plan, Qualified Bondholders were entitled to elect to receive either the Qualified Recovery or the Default Recovery. 

Non-Qualified Bondholders were entitled to elect to receive either the Non-Qualified Recovery or the Default Recovery. 

Under the RJ Plan, Eligible Bondholders were entitled to make an election of the form of their recovery during an election period 

that commenced on February 6, 2018 and ended on March 8, 2018. Holders that made valid recovery elections will be entitled to 
participate in settlement procedures that we expect to conduct shortly following the satisfaction or waiver of the conditions to the 
issuance of the new common shares set forth in the RJ Plan. 

Qualified Recovery 

Under the RJ Plan, the Qualified Recovery with respect to each US$1,000 of Bondholder Credits (or the equivalent in other 

currencies) will consist of: 

• US$195.61 aggregate principal amount of New Notes; 

•

179.09 New Shares, subject to reduction in the event that any common shares of Oi are subscribed in the pre-emptive offer 
of these common shares that Oi is required to conduct prior to issuing the common shares to the Bondholders, in which event 
such Bondholder will receive the cash proceeds related to the number of common shares by which such allocation was 
reduced;

13.75 common shares of Oi currently held by PTIF in ADS form, which are expected to be issued in the form of American 
Depositary Warrants; and 

• warrants to acquire 13.78 newly issued common shares of Oi for at an exercise price of US$0.01 per common shares, subject 

to reduction in the event that any common shares of Oi are subscribed in the pre-emptive offer of these common shares that 
Oi is required to conduct prior to issuing the common shares to the Bondholders. 

The New Notes will be senior unsecured obligations of Oi denominated in U.S. dollars that will mature on the seventh anniversary 
of their issuance. The New Notes will be initially be guaranteed, jointly and severally, each Telemar, Oi Mobile, Copart 4 and Copart 5. 
Upon the conclusion of the Dutch insolvency proceedings of Oi Coop and PTIF, Oi has agreed to cause Oi Coop and PTIF to guarantee 
the obligations of Oi under the New Notes. The New Notes will accrue interest from the Brazilian Confirmation Date. Interest on the 
New Notes will accrue: 

•

•

for the first three years (1) at a fixed rate of 10.0% per annum payable in cash on a semi-annual basis, or (2) a fixed rate of 
12.0% per annum, of which 8.0% shall be paid in cash on a semi-annual basis and 4.0% shall be payable by increasing the 
principal amount of the outstanding New Notes or by issuing paid-in-kind notes; and 

for the fourth year onwards, at a fixed rate of 10.0% per annum payable in cash on a semi-annual basis. 

Each Warrant will entitle its holder to subscribe for one common share at an exercise price of the equivalent in reais of US$0.01 
per common share. Each Warrant will be exercisable at any time, at the sole discretion of the holder, during a period of 90 days, which 
we refer to as the Exercise Period, beginning on the date that is 12 months after the date on which the Warrants are issued, unless the 
commencement of the Exercise Period is accelerated upon the earliest to occur of the events described below. 

If Oi calls a general shareholders’ meeting of Oi or meeting of Oi’s board of directors’ to approve the commencement of the rights 
offering relating to the cash capital increase described in Section 6 of the RJ Plan and in the Commitment Agreement, Oi will publish a 
Material Fact relating to that meeting at least 15 business days prior to that meeting in which Oi will notify holders of Warrants that the 
Exercise Period relating to the Warrants will commence on the date of publication of that Material Fact. 

In the event that any transaction occurs that results in the change of Oi’s “control” (as such term is defined in the RJ Plan), Oi will 

publish a Material Fact relating to that transaction in which Oi will notify holders of Warrants that the Exercise Period relating to the 
Warrants will commence on the date of the completion of such transaction. The RJ Plan defines “control” as (1) the ownership of 
partner rights that ensure to its holder, on a permanent basis, the majority of the votes in the social deliberations and the power to elect 
the majority of the company managers; and (2) the effective use of this power to direct social activities and guide the operation of the 
company’s bodies. 

In the event that the settlement procedures with respect to the Qualified Recovery are concluded with respect to the New Notes, 

the new common shares and the Warrants prior to the conclusion of the Dutch insolvency proceedings of PTIF, we expect to distribute 
the common shares of Oi currently held by PTIF in ADS form to Bondholders entitled to receive the Qualified Recovery upon the 
conclusion of the Dutch insolvency proceedings of PTIF. 

Non-Qualified Recovery 

Under the RJ Plan, the Non-Qualified Recovery with respect to each US1,000 of Bondholder Credits (or the equivalent in other 

currencies) will consist of a participation interest under a credit agreement to be entered into between the RJ Debtors and an 
administrative agent in a principal amount of US$500.

The Non-Qualified Credit Agreement will be a senior unsecured obligation of Oi. The Non-Qualified Credit Agreement will be 
initially be guaranteed, jointly and severally, by each Telemar, Oi Mobile, Copart 4 and Copart 5. Upon the conclusion of the Dutch 
insolvency proceedings of Oi Coop and PTIF, Oi has agreed to cause Oi Coop and PTIF to guarantee the obligations of Oi under the 
Non-Qualified Credit Agreement. Principal under the Non-Qualified Credit Agreement will be paid in 12 semiannual installments 
beginning in the 78th month following the Brazilian Confirmation Date in the amount of 4% of the outstanding principal for the first six 
semi-annual installments, 12.66% of the outstanding principal for the next five semi-annual installments and the remainder at maturity 
on the 12th anniversary of the effectiveness of the Non-Qualified Credit Agreement. The Non-Qualified Credit Agreement will accrue 
interest at the rate of 6% per annum from the Brazilian Confirmation Date. Interest will be capitalized to increase the principal balance 
under the Non-Qualified Credit Agreement on an annual basis, and will be paid together with principal beginning in the 78th month 
following the Brazilian Confirmation Date. 

Default Recovery 

Under the RJ Plan, Bondholders that were not Eligible Bondholders, did not make a valid election of the form of recovery for their 

Bondholder Credits, or do not participate in the settlement procedures will only be entitled to the Default Recovery with respect to the 
Bondholder Credits represented by their Bonds. 

As a result of the confirmation of the RJ Plan by the RJ Court, following the issuance by the U.S. Bankruptcy Court of an order 
recognizing the RJ Plan and the Confirmation Order, which we refer to as the U.S. Recognition Order, the Indentures governing the 
bonds issued by Oi and Oi Coop will be novated and Bondholder Credits represented by Bonds issued under those Indentures will 
entitle the holders of those Bonds (other than Bonds the holders of which receive the Qualified Recovery or the Non-Qualified 
Recovery in accordance with the settlement procedures) to the Default Recovery. Similarly, following (1) the homologation of the 
Dutch Composition Plan for PTIF by the Dutch Court (the “Homologation Order”) and the resulting automatic recognition of the Dutch 
Composition Plan for PTIF under English law pursuant to the European Insolvency Regulation (2015/848), and (2) the contractual 
release of the Oi guarantee of the bonds issued by PTIF pursuant to the terms of the PTIF Consent Solicitation, the Trust Deed 
governing the bonds issued by PTIF will be novated and Bondholder Credits represented by Bonds issued under the Trust Deed will 
entitle the holders of those Bonds (other than Bonds the holders of which receive the Qualified Recovery or the Non-Qualified 
Recovery in accordance with the settlement procedures) to the Default Recovery. 

Under the RJ Plan, the Default Recovery will consist of an unsecured right to receive payment of 100% of the principal amount of 

the Bondholder Credits represented by: 

•

•

bonds issued by Oi or Oi Coop in five annual, equal installments, commencing on the 20th anniversary of the date of the U.S. 
Recognition Order; and 

bond issued by PTIF in five annual, equal installments, commencing on the 20th anniversary of the date of the Homologation 
Order, which, in each case, we refer to as the Default Recovery Entitlement. 

A Bondholder’s Default Recovery Entitlement will be denominated in the currency of the Bonds with respect to which the Default 
Recovery Entitlement relates. The Default Recovery Entitlement with respect to Bonds denominated in U.S. dollars or euros will not 
bear any interest. The Default Recovery Entitlement with respect to Oi’s 9.75% senior notes due 2016 will bear interest at the Brazilian 
TR rate (payable together with the last installment of principal), which will accrue as additional principal amount of the Default 
Recovery Entitlement during until the 20th anniversary of the date of the U.S. Recognition Order, and thereafter be payable together 
with payments of principal amount of the Default Recovery Entitlement. The principal and accrued interest with respect to the Default 
Recovery Entitlement may be redeemed at any time and from time to time, in whole or in part, by the RJ Debtors at a redemption price 
of 15% of the aggregate principal amount of the Default Recovery Entitlement. 

Results of Recovery Elections 

As of the end of the election period, Qualified Bondholders with Bondholder Credits representing an aggregate of 

US$8,463 million of claims had elected to receive the Qualified Recovery and Non-Qualified Bondholders with Bondholder Credits 
representing an aggregate of US$187 million of claims had elected to receive the Non-Qualified Recovery. In the event that all such 
holders participate in the settlement procedures, we expect (1) to issue approximately US$1,655 million principal amount of New 
Notes, approximately 1,516 million new common shares and Warrants to subscribe to approximately 117 million new common shares, 
(2) that the aggregate principal amount of the Non-Qualified Credit Agreement will be approximately US$94 million, and (3) the 
holders of the remaining outstanding Bondholder Credits will be entitled to the Default Recovery with an aggregate principal amount of 
approximately US$1,094 million.

Under the RJ Plan, the claims of lenders under export credit facility agreements were classified as Class III claims. Under the RJ 

Plan, each of the lenders under these export credit facility agreements were entitled to make an election of the form of their recovery 
during an election period that commenced on February 6, 2018 and ended on February 26, 2018. Each of the lenders under export credit 
facility agreements elected to receive payment of the amount of their recognized claims, which will be paid in U.S. dollars in 24 semi-
annual installments beginning in the 66th month following the Brazilian Confirmation Date, in the amount of 2.0% of the recognized 
claims for the first 10 semi-annual installments, 5.7% of the recognized claims for the next 13 semi-annual installments and the

Unsecured Lines of Credit 

In May 2008, Telemar entered into an unsecured line of credit with a Brazilian financial institution in the aggregate amount of 
R$4,300 million to finance the acquisition of control of Oi. The principal of the loans under this unsecured line of credit was payable in 
seven equal annual installments, commencing in May 2010. As of December 31, 2017 and 2016, the aggregate amount of the claims 
under this unsecured line of credit recognized by the RJ Court was R$2,324 million. 

Under the RJ Plan, the claims of the lender under this unsecured line of credit were classified as Class III claims. Under the RJ 
Plan, the lender under this unsecured line of credit was entitled to make an election of the form of its recovery during an election period 
that commenced on February 6, 2018 and ended on February 26, 2018. The lender under this unsecured line of credit elected to receive 
payment of the amount of its recognized claims, which will be paid in reais in 24 semi-annual installments beginning in the 66th month 
following the Brazilian Confirmation Date, in the amount of 2.0% of the recognized claims for the first 10 semi-annual installments, 
5.7% of the recognized claims for the next 13 semi-annual installments and the remainder at maturity on the 17th anniversary of the 
Brazilian Confirmation Date. The recognized amount of these claims will accrue interest at the rate of 80% of the CDI rate from the 
Brazilian Confirmation Date. Interest will be capitalized to increase the recognized amount of these claims on an annual basis during 
the first 66 month following the Brazilian Confirmation Date, and will be paid semi-annually in cash thereafter through the final 
maturity. 

Real Estate Securitization Transaction 

In August 2010, Telemar transferred 162 real estate properties to our wholly-owned subsidiary Copart 4 and Oi transferred 101 
real estate properties to our wholly-owned subsidiary Copart 5. Telemar entered into lease contracts with terms of up to 12 years for the 
continued use of all of the properties transferred to Copart 4 and Oi entered into lease contracts with terms of up to 12 years for the 
continued use of all of the properties transferred to Copart 5. 

Copart 4 and Copart 5 assigned the receivables representing all payments under these leases to Brazilian Securities Companhia de 

Securitização, which issued Real Estate Receivables Certificates (Certificados de Recebíveis Imobiliários), or CRIs, backed by these 
receivables. The CRIs were purchased by Brazilian financial institutions. 

We received net proceeds from the assignment of lease receivables in the total aggregate amount of R$1,585 million on a 

consolidated basis, and recorded our obligations to make the assigned payments as short- and long-term debt in our consolidated 
financial statements. The proceeds raised in this transaction were used to repay short-term debt. In June 2012, each of Copart 4 and 
Copart 5 partially redeemed the CRIs that they had issued for an aggregate amount of R$393 million. As of December 31, 2017 and 
2016, the aggregate amount of the claims under our obligations to make the assigned payments recognized by the RJ Court was 
R$1,519 million. 

Under the RJ Plan, the creditors under the CRIs were classified as Class III claims. Under the RJ Plan, each of the creditors under 
the CRIs were entitled to make an election of the form of their recovery during an election period that commenced on February 6, 2018 
and ended on February 26, 2018. Each of creditors under the CRIs elected to receive payment of the principal of their recognized 
claims, which will be paid in reais in 24 semi-annual installments beginning in the 66th month following the Brazilian Confirmation 
Date, in the amount of 2.0% of the recognized claims for the first 10 semi-annual installments, 5.7% of the recognized claims for the 
next 13 semi-annual installments and the remainder at maturity on the 17th anniversary of the Brazilian Confirmation Date. The amount 
of these recognized claims will accrue interest at the rate of 80% of the CDI rate from the Brazilian Confirmation Date. Interest will be 
capitalized to increase the recognized amount of these claims on an annual basis during the first 66 month following the Brazilian 
Confirmation Date, and will be paid semi-annually in cash thereafter through the final maturity. 

Civil Contingencies – ANATEL 

As a result of the commencement of the RJ Proceedings on June 20, 2016, all outstanding claims of ANATEL against the RJ 

Debtors as of that date became subject to compromise under our RJ Proceedings. As of December 31, 2017 and 2016, the aggregate 
amount of the contingencies for claims of ANATEL recognized by the RJ Court was R$9,334 million and R$7,765, respectively.

Under the RJ Plan, claims of ANATEL were classified as Class III claims. Under the RJ Plan, liquidated claims of ANATEL 

outstanding as of June 20, 2016 have been novated and in calculating the recovery of ANATEL under these claims the amounts of all 
accrued interest included in these claims will be reduced by 50% and the amounts of all late charges included in these claims will be 
reduced by 25%. The remaining amount of these claims will be settled in 240 monthly installments, beginning on June 30, 2018, in the 
amount of 0.160% of the outstanding claims for the first 60 monthly installments, 0.330% of the outstanding claims for the next 60 
monthly installments, 0.500% of the outstanding claims for the next 60 monthly installments, 0.660% of the outstanding claims for the 
next 59 monthly installments, and the remainder at maturity on June 30, 2038. Beginning on July 31, 2018, the amounts of each 
monthly installment will be adjusted by the SELIC variation. Payments of monthly installments will be made through the application of 
judicial deposits related to these claims until the balance of these judicial deposits has been exhausted and thereafter will be payable in 
cash in reais. 

Under the RJ Plan, non-liquidated claims of ANATEL outstanding as of June 20, 2016 have been novated and ANATEL will be 

entitled to a recovery with respect to those clams similar to the Default Recovery described in “—Loans and Financing—Fixed Rate 
Notes—Default Recovery.” 

In the event that a legal rule is adopted in Brazil that regulates an alternative manner for the settlement of the claims of ANATEL 
outstanding as of June 20, 2016, the RJ Debtors may adopt the new regime, observing the terms and conditions set forth in Oi’s bylaws. 

Civil Contingencies – Other Claims 

As a result of the commencement of the RJ Proceedings on June 20, 2016, all outstanding unsecured civil claims against the RJ 
Debtors as of that date became subject to compromise under our RJ Proceedings. As of December 31, 2017 and 2016, the aggregate 
amount of the contingencies for civil claims (other than claims of ANATEL and other regulatory agencies) recognized by the RJ Court 
was R$2,929 million and R$3,096 million, respectively. For more information regarding these civil contingencies, see note 28 to our 
consolidated financial statements included in this annual report. 

Under the RJ Plan, unsecured civil claims against the RJ Debtors were classified as Class III and IV claims. Under the RJ Plan, if 

judicial deposits have been made with respect to adjudicated civil claims, holders of these civil claims that expressly agree with the 
amounts of the civil claims acknowledged by the RJ Debtors, including those indicated in the Second List of Creditors, and waive the 
right to offer, propose, or proceed with credit actions, qualifications, divergences, objections, or any other measure (including appeals) 
which aim at increasing the amounts of their civil claims, will be paid, subject to the reduction of the amount of any civil claim 
classified as a Class III claim as described below, through the application of judicial deposits related to these civil claims until the 
balance of the relevant judicial deposits has been exhausted. Any amount of a civil claim remaining unpaid after the application of the 
related judicial deposit will entitle the holder to a recovery with respect to the balance of that civil claim similar to the Default Recovery 
described in “—Loans and Financing—Fixed Rate Notes—Default Recovery.” Any amount of a civil claim remaining unpaid after the 
application of the related judicial deposit will entitle the holder to a recovery with respect to the balance of that civil claim similar to the 
Default Recovery described in “—Loans and Financing—Fixed Rate Notes—Default Recovery.” In the event that the related judicial 
deposit is greater than the amount that the holder of a civil claim is entitled to withdraw, the RJ Debtors will be entitled to withdraw the 
difference from the judicial deposit. 

The amount of the claim of a holder of civil claims (other than claims of ANATEL and other regulatory agencies) that have been 

classified as Class III claims will be reduced based on the amount of such civil claims as follows: 

• Civil claims of more than R$1,000 and equal to or less than R$5,000 will be reduced by 15%; 

• Civil claims of more than R$5,000 and equal to or less than R$10,000 will be reduced by 20%; 

• Civil claims of more than R$10,000 and equal to or less than R$150,000 will be reduced by 30%; and 

• Civil claims of more than R$150,000 will be reduced by 50%.

Trade Payables 

As a result of the commencement of the RJ Proceedings on June 20, 2016, all outstanding trade payables as of that date became 

subject to compromise under our RJ Proceedings. As of December 31, 2017 and 2016, the aggregate amount of the claims of our trade 
creditors recognized by the RJ Court was R$2,139 million and R$2,159 million, respectively. 

Under the RJ Plan, the claims of our trade creditors were classified as Class III or Class IV claims. Under the RJ Plan, each of 

these trade creditors were entitled to make an election of the form of their recovery during an election period that commenced on 
February 6, 2018 and ended on February 26, 2018. 

Trade creditors that, under the RJ Plan, continued to supply goods and/or services to the RJ Debtors without any unreasonable 

change in the terms and conditions and that do not have any on-going litigation against any of the RJ Debtors, other than litigation 
related to the RJ Proceeding were deemed to be “Strategic Supplier Creditors” under the RJ Plan. Strategic Supplier Creditors with 
claims of R$150,000 or less (or the equivalent in other currencies), other than claims arising from loans or other funding provided to Oi 
Coop, were entitled to elect to receive 100% of their claims in cash within 20 business days after the end of the election period. 
Strategic Supplier Creditors with claims of more than R$150,000 (or the equivalent in other currencies), other than claims arising from 
loans or other funding provided to Oi Coop, were entitled to elect to receive R$150,000 (or the equivalent in other currencies) in cash 
within 20 business days after the end of the election period and 90% of their remaining claims in cash in four equal annual installments, 
plus interest on the amount of their claims at the rate of TR plus 0.5% per annum for claims denominated in reais, and at the rate of 
0.5% per annum for claims denominated in U.S. dollars or euros. 

Trade creditors that were not deemed to be “Strategic Supplier Creditors” under the RJ Plan were entitled to elect to: 

•

•

•

receive the entire amount of their claim in cash in a single installment if the aggregate amount of their claims was less than 
or equal to R$1,000; 

receive R$1,000 in cash in a single installment with respect to the entire amount of their claim if the aggregate amount of 
their claims was more than R$1,000; or 

receive the entire amount of their claim under terms similar to (1) those described under “—Loans and 
Financing—Unsecured Lines of Credit” if their claims were denominated in reais, or (2) those described under “—Loans 
and Financing—Export Credit Agreements” if their claims were denominated in a currency other than reais. 

Trade creditors that did not elect one of these recovery options are entitled to a default recovery similar to the Default Recovery 
described in “—Loans and Financing—Fixed Rate Notes—Default Recovery.”

Labor Contingencies 

As a result of the commencement of the RJ Proceedings on June 20, 2016, all outstanding labor claims against the RJ Debtors as 
of that date became subject to compromise under our RJ Proceedings. As of December 31, 2017 and 2016, the aggregate amount of the 
contingencies for labor claims recognized by the RJ Court was R$899 million and R$752 million, respectively. For more information 
regarding these labor contingencies, see note 28 to our consolidated financial statements included in this annual report. 

Under the RJ Plan, labor claims were classified as Class I claims. Under the RJ Plan, generally all labor claims will be paid in five 
equal monthly installments, beginning on the 6-month anniversary of the Brazilian Confirmation Date. Labor claims not yet adjudicated 
will be paid in five equal monthly installments, beginning six months after a final, non-appealable ruling of the relevant court hearing a 
labor claim. 

Labor claims for which a judicial deposit has been posted by any of the RJ Debtors will be paid through the immediate 

disbursement of the amount deposited in court and, in the event that the related judicial deposit is lower than the labor claim listed by 
the RJ Debtors in the Second Creditor List, the judicial deposit shall be used to pay part of the labor claim and the outstanding balance 
of the labor claim will be paid after a decision is issued by the RJ Court that ratifies the amount due in five equal monthly installments, 
beginning six months after the Brazilian Confirmation Date. In the event that the related judicial deposit is greater than the amount of 
the labor claim, the RJ Debtors will be entitled to withdraw the difference from the judicial deposit. 

Labor claims for which no judicial deposit has been posted by any of the RJ Debtors will be paid through judicial deposits to be 

attached to the court records of the related case. 

Pension Plans 

As a result of the commencement of the RJ Proceedings on June 20, 2016, our obligations to fund certain of our post-retirement 
defined benefit plans as of that date became subject to compromise under our RJ Proceedings. As of each of December 31, 2017 and 
2016, the aggregate amount of our unfunded obligations under our post-retirement defined benefit plans the contingencies recognized 
by the RJ Court was R$560 million, all of which related to claims of FATL. 

Under the RJ Plan, our obligations to fund our post-retirement defined benefit plans were classified as Class I claims. Claims due 

to FATL will be payable in six annual, equal installments, beginning on the fifth anniversary of the Brazilian Confirmation Date and the 
amount due will bear interest at the rate of the National Consumer Price Index (INPC) plus 5.5% per annum from the Brazilian 
Confirmation Date. Interest will be capitalized to increase the principal balance of these claims on an annual basis during the first five 
years following the Brazilian Confirmation Date, and will be paid annually in cash thereafter through the final maturity. 

Capital Expenditures 

During 2017 and 2016, we modernized our core network, with a focus on infrastructure improvements and enhancing our 
customers’ experience, by making strategic investment decisions that allow us to do more with less. As a result, we expanded our fiber 
optic backbone, which enhanced our data traffic capabilities for fixed and mobile networks, to keep up with the growing demand, In 
addition, our performance on ANATEL’s network quality metrics improved. 

Our efforts to be more efficient in our capital expenditures in 2017 and 2016 include: (1) renegotiating contracts with our 

suppliers; (2) increasing our involvement in fixed network sharing, including RAN sharing on our 4G network; and (3) structural 
projects that increase the efficiency of services to both fixed and mobile broadband customers (i.e. faster downloads, higher quality HD 
video channels, and improved voice and video calls) and reduce infrastructure costs.

Our principal capital expenditures relate to a variety of projects designed to expand and upgrade our data transmission networks, 

our mobile services networks, our voice transmission networks, our information technology equipment and our telecommunications 
services infrastructure. 

Data Transmission Equipment Programs 

In our access networks, we have been engaged in a program of deploying FTTH technology to support our “triple play” and 
“quadruple play” services, using a GPON network engineered to support satellite video transport services, IP TV and RF overlay video 
services, internet with speeds up to 200 Mbps, and VoIP services. 

We have acquired and installed data communications equipment to convert elements of our networks that used ATM protocol over 

legacy copper wire and SDH protocols to MPLS protocol over optical fiber, which supports IP and permits the creation of VPNs 
through our MetroEthernet networks. We also deployed an optical switching layer based on optical transport network technology in 
order to provide more efficient use of our DWDM capacity, fast restorations, and IP routers traffic offloading. 

In 2015 Oi began implementing a new broadband data communications network architecture, which we refer to as the Single Edge 
project. This architecture enables Oi to offer access network services such as mobile, broadband, IPTV, and corporate customer links in 
a single platform, which eliminates the need for individual management of each type of access network, expedites the resolution of 
networks problems and minimizes maintenance and operation costs. 

In 2015, we transformed our IP backbone to expand its capacity and speed to operate 10/100 Gbps line rate interfaces on our new 

OTN/DWDM network over 30,000 km of fiber-optic cable. The OTN/DWDM network is designed to protect against interruptions in 
service caused by external events and accidents. Since January 2014, Our OTN/DWDM network has experienced an average annual 
growth of traffic, especially in data traffic, of more than 40% per year. 

In addition to expanding our IP backbone capacity, we are continuing to simplify our transport network architecture through the 
adoption of the single edge concept, which means using one single router to join our commercial, mobile and residential functions that 
would otherwise require many specialized routers. We believe that this network simplification will reduce both capital and operational 
expenditures.

We are implementing wireless local loop technology in areas not supported by our fixed-line network to provide service to our 

customers through our 2G network. 

We have undertaken a project to upgrade a portion of our mobile networks to enable us to increase the capacity of our mobile 

network. Since December 2007, when we acquired our authorizations to provide 3G services, we have engaged in a program of 
developing our 3G network. We are deploying new radio base stations and transceivers to improve our 3G coverage and quality in areas 
we already serve, reducing the level of signal congestion in these areas, and to expand our 3G service to municipalities in Regions I, II 
and III where we currently do not provide 3G service. We are continuing to upgrade portions of our 3G mobile network to support 
greater data rates through the HSPA+ standard. 

We performed capacity expansions in 35% of our existing 3G sites during 2017 to increase the speed of our 3G connection. 
Furthermore, in order to improve the experience of our data service users, we began granting our 2G users access to our 3G network by 
migrating the user’s data plan from 2G to 3G and upgrading their devices to be 3G compatible. 

4G Network 

In June 2012, we acquired the authorizations and radio frequency licenses necessary for us to commence the offering of 4G 
services throughout Brazil. We intend to offer 4G services throughout Brasil using LTE network technology and have begun deploying 
our 4G network. As part of this project, we have upgraded our existing mobile core to the LTE Evolved Packet Core, using an Evolved 
NodeB base station under a Radio Access Network that we will share with other Brazilian mobile services operators. 

We extended LTE services in 2015 to cities with over 200,000 inhabitants, including 88 new municipalities, to cities with over

100,000 inhabitants in 2016, including 151 new municipalities, and to cities with less than 100,000 inhabitants in 2017, including 529 
new municipalities as a result of obligations imposed by ANATEL. 

Voice Transmission Network Programs 

We are engaged in a program of investing in new equipment for our switching station to support next-generation networks to 
support offerings of new value-added services to our fixed-line customers. We believe that our investment in next-generation networks 
will: 

•

•

•

assist us in meeting the increased demand for long distance traffic, both domestic and international, through the use of VoIP; 

permit us to offer differentiated services, such voice over broadband; and 

significantly promote fixed-to-mobile convergence. 

As part of this program, we are concluding the deployment of an IP Multimedia Subsystem, or IMS, core that will facilitate our 
convergent voice, broadband and IP TV offerings. The IMS core not only will provide control for the VoIP resource but also integrated 
access control and authentication for all three services, significantly improving automation and speed for customer provisioning. 

We are also undertaking a program of removing and replacing smaller switching stations and integrating these operations with 

other switching stations to promote efficiency in our operations. 

We monitor the anticipated demands of new residential developments and the service demand growth of existing residential areas 

to ensure that we make adequate network equipment available to service the demands of these areas. 

Information Technology Services Programs 

We are investing in the expansion of supply of our cloud computing services in data centers, particularly in the State of São Paulo, 

in order to support the growing demand from our corporate customers. Our cloud computing services enable us to provide our 
customers with integrated telecommunications and information technology solutions.

Telecommunications Services Infrastructure Programs 

We are investing in several structural projects in order to improve and modernize our business support systems, or BSS, and 

operational support systems, or OSS, and consolidate duplicative systems resulting from integrating previously acquired companies, 
thereby optimizing our capital and operational expenditure investments. Based on the Telemanagement Forum frameworks and best 
practices, our main projects are unified customer relationship management; network provisioning services; order management; 
consolidation of network inventory; network planning, project and construction; network fault management; performance management; 
customer experience management; API management and digital self-care, among others. 

One of the primary projects connected to the OSS is related to assurance and quality. In March 2013, we began investing in a 

transition from a network centric monitoring system to a customer focused approach and thereby our network operations will migrate 
from network operations centers to service operations centers which will provide more efficient and customer-based support. We 
completed this project in January 2017. 

Another of our projects is to improve fulfillment by speeding up service creation and provisioning, reduce costly human 

intervention and increase overall customer quality of experience through automation of fulfillment processes. Our goal is to evolve as 
close as possible to a zero-touch provisioning process, without user intervention. This project began in March 2012 and was completed 
in December 2016. 

We are investing in the expansion of our transport networks in an effort to ensure that our networks continue to have the capacity 

to serve our customers and to support our plans to expand our services. In 2015, we activated the first chain in Brazil of entirely 100 
Gbps interfaces along our OTN/DWDM network of over 30,000 km of fiber optic cables connecting 12 Brazilian capitals (Rio de 
Janeiro, São Paulo, Belo Horizonte, Vitoria, Porto Alegre, Florianópolis, Curitiba, Salvador, Fortaleza, Recife, Teresina and Brasilia). 
This structural transformation is intended to increase the quality and data transmission capacity of our network as well as protect against 
interruptions in service caused by external events and accidents. 

We are also investing in projects to improve our networks by increasing the redundancy of our wire and fiber optic cable routes 
and establishing network mesh routes. We also perform preventive maintenance on sections of our network that have unusually high 
failure rates, and have a program to replace network elements in these sections. 

We are investing in the standardization of our facilities to deter fraud and improve the quality of our services, including the 

replacement of some of our public telephones. 

Off-Balance Sheet Arrangements 

We do not currently have any transactions involving off-balance sheet arrangements.

ITEM 6. DIRECTORS, SENIOR MANAGEMENT AND EMPLOYEES 

Oi’s board of directors (conselho de administração) and Oi’s board of executive officers (diretoria) are responsible for operating 

our business. 

Board of Directors 

Oi’s board of directors is a decision-making body responsible for, among other things, determining policies and guidelines for our 
business and Oi’s wholly-owned subsidiaries and controlled companies. Oi’s board of directors also supervises Oi’s board of executive 
officers and monitors its implementation of the policies and guidelines that are established from time to time by the board of directors. 
Under the Brazilian Corporate Law, Oi’s board of directors is also responsible for hiring independent accountants. 

Oi’s by-laws provide for a board of directors of up to 11 members and an equal number of alternate members. During periods of 
absence or temporary unavailability of a regular member of Oi’s board of directors, the corresponding alternate member substitutes for 
the absent or unavailable regular member. 

Generally, the members of Oi’s board of directors are elected at general meetings of shareholders for two-year terms and are 
eligible for reelection, pursuant to Oi’s by-laws. Members of Oi’s board of directors are subject to removal at any time with or without 
cause at a general meeting of shareholders. Oi’s by-laws do not contain any citizenship or residency requirements for members of Oi’s 
board of directors. Oi’s board of directors is presided over by the chairman of the board of directors, and, in his absence, on an interim 
basis, by his designated alternate. Typically, the chairman of Oi’s board of directors is elected by the general meeting of shareholders 
that elects the directors. Oi’s by-laws provide that the chairman of Oi’s board of directors may not serve as Oi’s chief executive officer. 

The RJ Plan, however, provides for a new framework of corporate governance rules that will apply with respect to Oi’s board of 

directors during the effectiveness of the RJ Plan, as described below, superseding the provisions of Oi’s by-laws. 

On July 14, 2016, the RJ Court granted a request made by ANATEL that the RJ Court determine that prior approval from 

ANATEL is required for, among other things, the possible transfer of Oi’s corporate control, including the replacement of Oi’s board of 
directors. 

On November 8, 2016, ANATEL issued an order requiring that Oi notify its Superintendence of Competition of the dates of 
meetings of Oi’s board of directors so that it could send a representative to attend such meetings. On January 6, 2017, ANATEL issued 
an additional order conditioning its approval of the entry of Société Mondiale into Oi’s controlling block on the continued compliance 
with this obligation, among others, as well as the submission of any changes to Oi’s board of directors, including changes with respect 
to alternate members, for the prior approval by ANATEL. 

On January 15, 2018, ANATEL approved the board of directors appointed pursuant to Section 9.2 of the RJ Plan and set forth in 

Exhibit 9.2 of the RJ Plan, or the Transitional Board, effective as from the date of approval of the RJ Plan on December 20, 2017, in 
accordance with the RJ Plan. For more information about the members of the board of directors who held office prior to the date of 
approval of the RJ Plan, see “Item 4. Information on the Company—Our Recent History and Development—Changes to the 
Membership of Our Board of Directors and Board of Executive Officers.” Members of the Transitional Board do not have alternates 
and may not be removed until a new board of directors, or the New Board, is elected by a general shareholders’ meeting that is required 
to be held within 45 business days following the conclusion of the Capitalization of Credits Capital Increase, as set forth in Section 9.3 
of the RJ Plan. The Transitional Board shall call this general shareholders’ meeting within five business days following the conclusion 
of the Capitalization of Credits Capital Increase. 

The Transitional Board is presided over by the chairman of the Transitional Board, and, in his absence, on an interim basis, by the 

vice-chairman of the Transitional Board. In accordance with Oi’s by-laws, decisions of the Transitional Board require a quorum of a 
majority of the directors and are taken by a majority vote of those directors present. A director may not cast votes with respect to 
matters in which he has a conflicting interest. In the event of a tie, the chairman of the Transitional Board shall cast the deciding vote. In 
addition to their ordinary course functions provided under Oi’s by-laws, the members of the Transitional Board must oversee the 
execution of the terms of the RJ Plan.

All prior members or alternates of the Board of Directors who were not designated as members of the Transitional Board of 
Directors pursuant to Section 9.2 of the Plan have been suspended from their duties, including as members of Oi’s advisory committees, 
and therefore cannot participate of any meeting of the Transitional Board of Directors. These members and alternates (a) shall be 
formally replaced by operation of the RJ Plan after the investiture of the New Board in accordance with the RJ Plan and the applicable 
legislation in Brazil, or (b) shall be removed due to the expiration of their terms of office, whichever occurs first. 

Pursuant to Section 9.3 of the RJ Plan, the New Board will be composed of 11 members and no alternate members, all of whom 

must be independent as defined in Oi’s by-laws, provided that one such member shall be Mr. Eleazar de Carvalho Filho (see 
“—Directors—Eleazar de Carvalho Filho”). The members of the New Board will be chosen by the Transitional Board and will serve for 
a term of two years. The members of the New Board may not be removed from office, except due to gross mistake, willful misconduct, 
gross negligence, abuse of term of office or violation of fiduciary duties in accordance with applicable law. Following the expiration of 
the term of the New Board, the election of subsequent boards of directors will follow the rules established by Oi’s by-laws and the 
Brazilian Corporate Law. 

The following table sets forth certain information with respect to the current members of the Transitional Board.

(1) On March 7, 2018, the RJ Court suspended the voting rights of the certain shareholders of Oi that participated in the purported extraordinary general shareholders’ 
meeting held on February 7, 2018, including Bratel S.à r.l and Société Mondiale, and ordered the removal of the members of Oi’s board of directors that had been 
elected/indicated by such shareholders them the completion of the Capitalization of Credits Capital Increase as part of the RJ Plan. As a result, Luis Maria Viana 
Palha da Silva, Pedro Zañartu Gubert Morais Leitão and Hélio Calixto da Costa were temporarily removed as members of Oi’s board of directors effective on 
March 7, 2018. Hélio Calixto da Costa also resigned as a member of Oi’s board of executive officers. The judicial decision also ordered the subpoena of the current 
executive officers of Oi and the shareholders whose voting rights were suspended, to express their interest in establishing a mediation proceeding. Oi (on behalf of 
itself and its executive officer), Bratel S.à r.l and Société Mondiale have manifested their interest in a mediation. Oi filed a petition stating that, since Société 
Mondiale has sold its shares and is no longer a shareholder of Oi, it should not be a part of the mediation. Despite Oi’s position, the RJ Court issued a decision 
ordering the mediation to be initiated.

Temporarily Removed Directors 

On March 7, 2018, the RJ Court suspended the voting rights of the certain shareholders of Oi that participated in the purported 
extraordinary general shareholders’ meeting held on February 7, 2018, including Bratel S.à r.l and Société Mondiale, and ordered the 
removal of the members of Oi’s board of directors that had been elected/indicated by such shareholders them the completion of the 
Capitalization of Credits Capital Increase as part of the RJ Plan. As a result, Luis Maria Viana Palha da Silva, Pedro Zañartu Gubert 
Morais Leitão and Hélio Calixto da Costa were temporarily removed as members of Oi’s board of directors effective on March 7, 2018. 
Hélio Calixto da Costa also resigned as a member of Oi’s board of executive officers. The judicial decision also ordered the subpoena 
of the current executive officers of Oi and the shareholders whose voting rights were suspended, to express their interest in establishing 
a mediation proceeding. Oi (on behalf of itself and its executive officer), Bratel S.à r.l and Société Mondiale have manifested their 
interest in a mediation. Oi filed a petition stating that, since Société Mondiale has sold its shares and is no longer a shareholder of Oi, it 
should not be a part of the mediation. Despite Oi’s position, the RJ Court issued a decision ordering the mediation to be initiated.

Alternate Directors 

As of the date of this annual report, Oi’s board of directors does not have any alternate members. 

Executive Officers 

The board of executive officers is Oi’s executive management body. Oi’s executive officers are Oi’s legal representatives and are 

responsible for Oi’s internal organization and day-to-day operations and the implementation of the general policies and guidelines 
established from time to time by Oi’s board of directors. 

Oi’s by-laws require that the board of executive officers consist of between three and six members, including a chief executive 

officer, a chief financial officer, investor relations officer and chief legal officer. Oi’s by-laws provide that Oi’s chief executive officer 
may not serve as chairman of Oi’s board of directors. Each officer is responsible for business areas that Oi’s board of directors assigns 
to them and, other than Oi’s chief executive officer and Oi’s chief financial officer, need not have formal titles (other than the title of 
executive officer or “Diretor”). 

Generally, the members of Oi’s board of executive officers are elected by Oi’s board of directors for two-year terms and are 

eligible for reelection. Oi’s board of directors may remove any executive officer from office at any time with or without cause. 
According to the Brazilian Corporate Law, executive officers must be residents of Brazil but need not be shareholders of Oi. Oi’s board 
of executive officers holds meetings when called by Oi’s chief executive officer or any two other members of Oi’s board of executive 
officers. 

The RJ Plan, however, provides for a new framework of corporate governance rules that will apply with respect to Oi’s board of 

executive officers during the effectiveness of the RJ Plan, superseding the provisions of Oi’s by-laws. Pursuant to Section 9.1 of the RJ 
Plan, Eurico De Jesus Teles Neto, Carlos Augusto Machado Pereira de Almeida Brandão and José Claudio Moreira Gonçalves may not 
be removed from their positions as chief executive officer, chief financial officer/investor relations officer and chief operating officer, 
respectively, during the Transitional Period, which is defined as the period between (1) the date of approval of the RJ Plan, which 
occurred on December 20, 2017, and the earlier to occur of (2) (i) the conclusion of the Capitalization of Credits Capital Increase, 
(ii) twelve months from the date of the Judicial Ratification of the RJ Plan and (iii) February 28, 2019. After the Transitional Period, the 
Transitional Board or the New Board, as the case may be, may freely appoint a new board of executive officers, provided that Mr. Teles 
and Mr. Brandão must remain on the board of executive officers as chief executive officer and chief financial officer/investor relations 
officer, respectively, until the closing of the RJ Plan, which shall occur upon the verification of the compliance of all obligations set 
forth in the RJ Plan that expire within two years of the Judicial Ratification of the RJ Plan; provided that, if Mr. Teles and Mr. Brandão 
are removed from their positions as chief executive officer and chief financial officer/investor relations officer, respectively, prior to the 
closing of the RJ Plan, then they receive the compensation packages to which they are currently entitled. 

The following table sets forth certain information with respect to the current members of Oi’s board of executive officers.

Fiscal Council 

The Brazilian Corporate Law requires Oi to establish a permanent or non-permanent fiscal council (conselho fiscal). Oi’s by-laws 
provide for a permanent fiscal council composed of between three and five members and their respective alternate members. The fiscal 
council is a separate corporate body independent of Oi’s board of directors, Oi’s board of executive officers and Oi’s independent 
accountants. The primary responsibility of the fiscal council is to review Oi’s management’s activities and Oi’s financial statements and 
to report their findings to Oi’s shareholders. 

The members of Oi’s fiscal council are elected by Oi’s shareholders at the annual shareholders’ meeting for one-year terms and 
are eligible for reelection. The terms of the members of Oi’s fiscal council expire at the annual shareholders’ meeting in 2019. Under 
the Brazilian Corporate Law, the fiscal council may not contain members who are members of Oi’s board of directors or Oi’s board of 
executive officers, spouses or relatives of any member of Oi’s board of directors or Oi’s board of executive officers, or our employees. 
To be eligible to serve on Oi’s fiscal council, a person must be a resident of Brazil and either be a university graduate or have been a 
company officer or fiscal council member of another Brazilian company for at least three years prior to election to Oi’s fiscal council. 
Holders of preferred shares without voting rights and non-controlling common shareholders that together hold at least 10.0% of Oi’s 
voting share capital are each entitled to elect one member and his or her respective alternate to the fiscal council.

Compensation 

According to Oi’s by-laws, Oi’s shareholders are responsible for establishing the aggregate compensation we pay to the members 
of Oi’s board of directors, board of executive officers and fiscal council. Oi’s shareholders determine this compensation at Oi’s annual 
shareholders’ meeting. Once aggregate compensation is established, Oi’s board of directors is responsible for distributing such 
aggregate compensation individually to the members of Oi’s board of directors and Oi’s board of executive officers in compliance with 
Oi’s by-laws. 

The aggregate compensation paid by us to all members of Oi’s board of directors, board of executive officers and fiscal council 

for services in all capacities in 2017 and 2016 was R$55.6 million and R$39.3 million, respectively. This amount includes pension, 
retirement or similar benefits for Oi’s officers and directors. At Oi’s 2018 annual shareholders’ meeting, Oi’s shareholders established 
the following compensation for the year 2018: 

•

•

•

board of directors (including aggregate directors): an aggregate limit of approximately R$6.9 million; 

board of executive officers: an aggregate limit of approximately R$74.6 million; and 

fiscal council: the minimum amount established under Paragraph 3 of Article 162 of the Brazilian Corporate Law. 

Oi compensates its alternate directors on a monthly basis, and compensation is not contingent upon attendance at the meetings of 

the board of directors. Oi compensates alternate members of its fiscal council for each meeting of the fiscal council that they attend. 

Oi’s executive officers receive the same benefits generally provided to our employees, such as medical (including dental) 
assistance, private pension plan and meal vouchers. Like our employees, Oi’s executive officers also receive an annual bonus equal to 
one-month’s salary (known as the “thirteenth” (monthly) salary in Brazil), an additional one-third of one-month’s salary for vacation, 
and contributions of 8.0% of their salary into a defined contribution pension fund known as the Guarantee Fund for Time of Service 
(Fundo de Garantia por Tempo de Serviço). Members of Oi’s board of directors and fiscal council are not entitled to these benefits. 

Members of Oi’s board of directors, board of executive officers and fiscal council are not parties to contracts providing for 

benefits upon the termination of employment other than, in the case of executive officers, the benefits described above. 

Long-Term Incentive Program 

On March 13, 2015, Oi’s board of directors approved a long-term incentive plan for certain of Oi’s executives. The purpose of the 
long-term incentive plan is to encourage integration, align the interests of management with that of shareholders and retain our strategic 
executives in the medium- and long-term. The long-term incentive plan program ran from 2015 until 2017. Compensation under the 
long-term incentive plan, calculated based on Oi’s share price, was paid in two annual installments in 2016 and 2017, with one 
remaining installment to be paid in 2018. In 2016 and 2017, we paid aggregate amounts of R$15.7 million and R$$13.6 million, 
respectively, pursuant to the long-term incentive plan.

We negotiate separate collective bargaining agreements with two union committees each representing the local unions in several 
Brazilian states. New collective bargaining agreements are negotiated every year. We maintain good relations with each of the unions 
representing our employees. As of December 31, 2017, approximately 41.6% of the employees of our company were members of state 
labor unions associated either with the National Federation of Telecommunications Workers (Federação Nacional dos Trabalhadores 
em Telecomunicações), or Fenattel, or with the Interstate Federation of Telecommunications Workers (Federação Interestadual dos 
Trabalhadores em Telecomunicações), or Fittel. We have never experienced a strike that had a material effect on our operations.

PBS-A Plan 

Since the privatization of Telebrás, the Sistel Benefits Plan (Plano de Benefícios da Sistel – Assistidos), or PBS-A plan, a defined 

benefit plan, has been sponsored by the fixed-line telecommunications companies that resulted from the privatization of Telebrás, 
including our company and TNL. The PBS-A plan is self-funded and has been closed to new members since January 2000. 
Contributions to the PBS-A plan are contingent on the determination of an accumulated deficit and we are jointly and severally liable, 
along with other fixed-line telecommunications companies, for 100% of any insufficiency in payments owed to members of the PBS-A 
plan. As of December 31, 2017 and 2016, the PBS-A plan had surpluses of R$2,787 million and R$2,388 million, respectively. We 
were not required to make contributions to the PBS-A plan in 2017 or 2016. 

PAMA Plan and PCE Plan 

Since the privatization of Telebrás, the Medical Assistance Plan to the Retired (Plano de Assistência Médica ao Aposentado), or 
PAMA, a health-care plan managed by Sistel, has been sponsored by the fixed-line telecommunications companies that resulted from 
the privatization of Telebrás, including our company. The PAMA plan has been closed to new members since February 2000, other than 
new beneficiaries of current members and employees that are covered by the PBS-A plan who have not yet elected to join the PAMA 
plan. In December 2003, we and the other telecommunications companies that resulted from the privatization of Telebrás began 
sponsoring the PCE –Special Coverage Plan, or the PCE plan, a health-care plan managed by Sistel. The PCE plan is open to employees 
that are covered by the PAMA plan. From February to July 2004, December 2005 to April 2006, June to September 2008, July 2009 to 
February 2010, March to November 2010, February 2011 to March 2012 and March 2012 until today, we offered incentives to our 
employees to migrate from the PAMA plan to the PCE plan. 

In October 2015, in compliance with a court order, Sistel transferred the R$3,042 million surplus in the PBS-A plan to the PAMA 
plan to ensure the solvency of the PAMA plan. Of the total amount transferred, R$2,127 million is related to the plans sponsored by the 
company, apportioned proportionally to the obligations of the defined benefit plan. 

As of December 31, 2017 and 2016, the PAMA plan had surpluses of R$129 million and R$395 million, respectively. We were 

not required to make contributions to the PAMA plan in 2017 or 2016. 

Fundação Atlântico de Seguridade Social 

FATL is a not-for-profit, independent private pension fund that manages pension plans for the employees of its plans’ sponsors. 

PBS-TNCP Plan 

Since the privatization of Telebrás, our subsidiary Tele Norte Celular Participações S.A., or TNCP, has sponsored the Sistel 
Benefits Plan – TNCP (Plano de Benefícios da Sistel – TNCP), or PBS-TNCP plan. The PBS-TNCP plan has been closed to new 
members since April 2004. Contributions to the PBS-TNCP plan are contingent on the determination of an accumulated deficit. As a 
result of the corporate reorganization and TNL’s earlier acquisition of control of TNCP, we are liable for 100% of any insufficiency in 
payments owed to members of the PBS-TNCP plan. Since January 2016, the PBS-TNCP plan has been managed by FATL. As of 
December 31, 2017 and 2016, the PBS-TNCP plan had surpluses of R$28 million and R$25 million, respectively. We made 
contributions to the PBS-TNCP plan of less than R$1 million in 2017 or 2016. 

CELPREV Plan 

In March 2004, Amazônia Celular S.A., or Amazônia, a subsidiary of TNCP, began sponsoring the CelPrev Amazônia, or 
CELPREV, plan, a defined contribution plan managed by Sistel. Since January 2016, the CELPREV plan has been managed by FATL. 
The CELPREV plan was offered to employees of Amazônia who did not participate in the PBS-TNCP plan, as well as to its new 
employees. Participants in the PBS-TNCP plan were encouraged to migrate to the CELPREV plan. Approximately 27.3% of 
participants in the PBS-TNCP plan migrated to the CELPREV plan. As of December 31, 2017 and 2016, the CELPREV plan had 
surpluses of R$0.1 million and R$2.4 million, respectively. We made contributions to the CELPREV plan of less than R$1 million in 
2017 or 2016.

TCSPREV Plan 

In December 1999, we and the other companies that participate in the plans managed by Sistel agreed to withdraw sponsorship of 

these plans and each company agreed to establish its own separate new plan for these participants. In February 2000, we began 
sponsoring the TCSPREV Plan, a private defined contribution pension plan and settled benefit plan. Approximately 80% of participants 
in the PBS-A plan migrated to the TSCPREV plan. In March 2005, Fundação 14 de Previdência Privada, or Fundação 14, a private 
not-for-profit pension fund created by Brasil Telecom Holding in 2004 to manage the TSCPREV plan, began managing the TSCPREV 
plan. In January 2010, FATL began managing the TSCPREV plan. 

The TCSPREV plan offers three categories of benefits to its members: (1) risk benefits, which are funded according to the defined 

benefit method; (2) programmable benefits, which are funded according to the defined contribution method; and (3) proportional paid 
benefits, applicable to those employees who migrated to a defined contribution method with their rights reserved as contributors to the 
defined benefit system. This plan is closed to new entrants. We are liable for any deficits incurred by the TCSPREV plan according to 
the existing proportion of the contributions we make to this plan. As of December 31, 2017 and 2016, the TCSPREV plan had surpluses 
of R$1,329 million and R$1,273 million, respectively. We were not required to make contributions to the TCSPREV plan in 2017 or 
2016. 

BrTPREV Plan 

In 2000, as a result of our acquisition of CRT—Companhia Riograndense de Telecomunicações, or CRT, we assumed liability for 

retirement benefits to CRT’s employees by means of the Fundador/Alternativo plan, a defined benefit plan, which was managed by 
Fundação BrTPREV, a private not-for-profit pension fund created by CRT in 1971 to manage the CRT plans. This plan has been closed 
to new members since October 2002. 

In October 2002, we began sponsoring the BrTPREV plan, a private defined contribution plan. Approximately 96% of our active 

employees that were participants in the Fundador/Alternativo plan migrated to the BrTPREV plan. This plan was offered to our new 
employees from March 2003 to February 2005, when it was closed to new participants. In March 2005, Fundação BrTPREV began 
managing these plans. In January 2010, FATL began managing the Fundador/Alternativo plan and the BrTPREV plan. In July 2012, the 
Fundador/Alternativo plan was merged into the BrTPREV plan, and participants and beneficiaries of the Fundador/Alternativo plan 
automatically became members of the BrTPREV plan. 

The BrTPREV plan offers three categories of benefits to its members: (1) risk benefits, which are funded according to the defined 

benefit method; (2) programmable benefits, which are funded according to the defined contribution method; (3) proportional paid 
benefits, applicable to those employees who migrated to a defined contribution method with their rights preserved as contributors to the 
defined benefit system. We are liable for any deficits incurred by the BrTPREV plan according to the existing proportion of the 
contributions we make to this plan. As of December 31, 2017 and 2016, the BrTPREV plan had deficits of R$213 million and 
R$93 million, respectively. However, the BrTPREV plan holds a large portfolio of federal government bonds (NTN-B) carried to 
maturity, which significantly offsets the deficits. This position, which is recognized by Resolution No. 16/2014 of the National Council 
of Supplementary Pensions (CNPC), reduces the deficit recorded as of December 31, 2016 of R$47 million. 

In 2012, as sponsor of the BrTPREV Plan, Oi entered into a financial obligation agreement with FATL with respect to deficits 

under the BrTPREV Plan. This obligation is classified as a Class I claim under the RJ Plan. For more information about this claim, see 
“Item 5. Operating and Financial Review and Prospects—Liabilities Subject to Compromise—Pension Plans.” As of each of 
December 31, 2017 and 2016, the aggregate amount of the claim recognized by the RJ Court was R$560 million.

PBS Telemar Plan 

In September 2000, Telemar began sponsoring the PBS-Telemar plan, a private defined benefit plan offered to Telemar’s 

employees. In February 2005, FATL began managing the PBS Telemar plan. As a result of the corporate reorganization, we have 
assumed Telemar’s obligations under the PBS-Telemar plan. 

The PBS-Telemar plan has the same characteristics as the PBS-A plan. The PBS-Telemar plan was closed to new participants in 

September 2000. We are responsible for any deficits incurred by the PBS-Telemar plan according to the existing proportion of the 
contributions we make to this plan and those made by participants. As of December 31, 2017 and 2016, the PBS-Telemar plan had 
surpluses of R$53 million and R$28 million, respectively. We made contributions to the plan of less than R$1 million in each of 2017 
and 2016. 

TelemarPrev Plan 

In September 2000, Telemar began sponsoring the TelemarPrev plan, a private defined contribution pension plan. Approximately 

96% of participants in the PBS-Telemar plan migrated to the TelemarPrev plan. In February 2005, FATL began managing the 
TelemarPrev plan. As a result of the corporate reorganization, we have assumed Telemar’s obligations under the TelemarPrev plan. 

The TelemarPrev plan offers two categories of benefits to its members: (1) risk benefits, which are funded according to the 
defined benefit method; and (2) programmable benefits, which are funded according to the defined contribution method. We are liable 
for any deficits incurred by the TelemarPrev plan according to the proportion of the contributions we make to this plan. As of 
December 31, 2017 and 2016, the TelemarPrev plan had deficits of R$26 million and R$45 million, respectively. However, the 
TelemarPrev plan holds a large portfolio of federal government bonds (NTN-B) carried to maturity, which significantly offsets the 
deficits. This position, which is recognized by Resolution No. 16/2014 of the National Council of Supplementary Pensions (CNPC), is 
higher than the deficit recorded, resulting in a positive net result in 2017 and 2016 of R$317 million and R$362 million, respectively. 

PAMEC-BrT Plan 

We also provide health care benefits for some retirees and pensioners that are members of the TCSPREV plan under the 
PAMEC-BrT plan, a defined benefit plan. The contributions for the PAMEC-BrT plan were fully paid in July 1998 through a single 
payment. In November 2007, the assets and liabilities of PAMEC-BrT were transferred from Fundação 14 to us, and we began 
managing the plan. As a result of the transfer, we do not recognize assets to cover current expenses and we fully recognize the actuarial 
obligations as liabilities. As of December 31, 2017 and 2016, the PAMEC-BrT plan had deficits of R$3,3 million and R$3,2 million, 
respectively. We made contributions to the PAMEC-BrT plan of less than R$1 million in 2017 or 2016. 

For more information on our pension benefit plans, see note 22 to our consolidated financial statements included in this annual 

report. 

Medical, Dental and Employee Assistance Benefits 

We provide our employees with medical and dental assistance, pharmacy and prescription drug assistance, group life insurance 
and meal, food and transportation assistance. We and our employees cover the costs of these benefits on a shared basis. In 2017, we 
contributed R$250 million to the medical and dental assistance plans, R$8 million to the occupational medicine plans, R$300 million 
for the Worker’s Food Program (Programa de Alimentação do Trabalhador), or PAT, and R$79 million to the other benefits programs. 
In 2016, we contributed R$210 million to the medical and dental assistance plans, R$10 million to the occupational medicine plans, 
R$303 million for the PAT, and R$82 million to the other benefits programs.

Profit Sharing Plans 

The operational targets are part of a profit sharing plan implemented by the Company as an incentive for employees to pursue our 
goals and to align employees’ interests with those of our shareholders. Profit sharing occurs if financial and operational targets defined 
annually by our board of directors are achieved. As of December 31, 2017, we had provisioned R$310 million to be distributed in 
bonuses with respect to 2017. As of December 31, 2016, we had provisioned R$74 million to be distributed in bonuses with respect to 
2016. 

We also have implemented a profit sharing plan as an incentive for employees to pursue our goals and to align employees’ 
interests with those of our shareholders. Profit sharing occurs if economic value-added targets and other targets defined annually by our 
board of directors are achieved. 

Education and Training 

We contribute to the professional qualification of our employees by offering training for the development of organizational and 

technical skills. In 2017, we offered approximately 1,430,000 hours of training, and we invested approximately R$22 million in the 
qualification and training of our employees. In 2016, we offered approximately 1,600,000 hours of training, and we invested 
approximately R$21 million in the qualification and training of our employees. 

ITEM 7. MAJOR SHAREHOLDERS AND RELATED PARTY TRANSACTIONS 

Major Shareholders 

Oi has two outstanding classes of share capital: common shares and preferred shares with no par value. Generally, only Oi’s 
common shares have voting rights. Oi’s preferred shares have voting rights only in exceptional circumstances. Currently, Oi’s preferred 
shares have full voting rights pursuant to Oi’s by-laws as a result of Oi’s failure to make mandatory dividend payments since 2014. For 
more information, see “Item 8. Financial Information—Dividends and Dividend Policy—Payment of Dividends” and “Item 10. 
Additional Information—Description of Oi’s By-laws—Voting Rights—Voting Rights of Preferred Shares.” 

As of May 10, 2018, Oi had issued 825,760,902 total shares, consisting of 668,033,661 issued common shares and 157,727,241 

issued preferred shares, including 148,282,000 common shares and 1,811,755 preferred shares held in treasury. 

As of May 10, 2018, Oi had approximately 1.09 million shareholders, including 45 U.S. resident holders of Oi’s common shares 

and approximately 44 U.S. resident holders of Oi’s preferred shares (including The Bank of New York Mellon, as depositary under Oi’s 
American Depositary Receipt, or ADR, facilities). As of May 10, 2018, there were 59,547,231 common shares (including common 
shares represented by ADSs) and 49,674,843 preferred shares (including preferred shares represented by ADSs) held by U.S. resident 
holders. 

Under Oi’s by-laws, any shareholder or group of shareholders, representing the same interest or bound by a voting agreement, that 

hold or may hold in the future, alone or jointly, interest in Oi representing more than 15% of Oi’s voting capital shall have its voting 
rights limited to 15% of the shares with voting rights, subject to certain exceptions. See “Item 10. Additional Information—Description

Under the RJ Plan, certain groups of creditors were entitled to make elections with respect to the form of the recovery that they 

were entitled to receive. The period to make these elections ended on March 8, 2018. See “Item 4. Information on the Company—Our 
Recent History and Development—Our Judicial Reorganization Proceedings—Implementation of the Judicial Reorganization Plan.” 
Based on the results of this election, following the conclusion of the Qualified Recovery Settlement Procedure and assuming that (1) all 
Qualified Bondholders who elected to receive the Qualified Recovery successfully participate in the Qualified Recovery Settlement 
Procedure and (2) none of Oi’s existing shareholders exercise their rights of first refusal granted under Brazilian law to subscribe for 
New Shares in connection with the Qualified Recovery Settlement Procedure, the exercise of which would reduce the number of New 
Shares and corresponding number Warrants that Qualified Bondholders will receive under the RJ Plan, we expect that existing 
shareholders’ ownership interests in Oi will be diluted by 72.1%, with no single shareholder expected to own 10% or more of Oi’s 
voting or total shares. Under the RJ Plan, the Qualified Recovery Settlement Procedure is required to occur on or prior to July 31, 2018. 
For more information about the possible effects of the failure of the Qualified Recovery Settlement Procedure to take place on or prior 
to July 31, 2018, see “Item 3. Risk Factors—Risks Relating to Our Financial Restructuring—If we fail to comply with certain 
conditions subsequent set forth in the RJ Plan, the RJ Plan may terminate and we may be declared bankrupt under Brazilian law and 
liquidated.”

72% was available between March 31, 2017 and March 31, 2018;

36% will be available between March 31, 2019 and March 31, 2020; and 

18% will be available between March 31, 2020 and March 31, 2021, 

in each case, less the number of shares with respect to the PT Option has been previously exercised. As of May 10, 2018, Pharol had not 
exercised the PT Option with respect to any of Oi’s shares and, as a result, the option over 21,820,041 of Oi’s common shares and 
43,640,082 of Oi’s preferred shares has lapsed. The exercise prices under the PT Option are R$20.104 per common share and R$18.529 
per preferred share, in each case as adjusted by the CDI rate plus 1.5% per annum, calculated pro rata temporis, from March 31, 2015 
to the date of the effective payment of the exercise price. 

Oi is not required to maintain the shares subject to the PT Option in treasury. In the event that, at the time of exercise of the PT 
Option, PTIF and/or any of Oi’s other subsidiaries do not hold, in treasury, the number of shares with respect to which Pharol exercises 
the PT Option, the PT Option may be financially settled through payment by PTIF of the amount corresponding to the difference 
between the market price of the shares and the exercise price corresponding to these shares. 

We may terminate the PT Option if (1) the by-laws of Pharol are amended to remove or amend the provision of those by-laws that 
limits the voting right to 10% of all votes corresponding to the capital stock of Pharol, except if this removal or amendment is required 
by law or by order of a competent governmental authority; (2) Pharol directly or indirectly engages in activities that compete with the 
activities Oi or Oi’s subsidiaries in the countries in which we or they operate; or (3) Pharol violates certain obligations under the PT 
Option Agreement. 

Prior to the earlier of the expiration or full exercise of the PT Option, Pharol may not purchase shares of Oi, directly or indirectly, 

in any manner other than by exercising the PT Option. If the PT Option is exercised, Pharol will undertake its best efforts to integrate 
the shareholder bases of Pharol and Oi in the shortest time possible. 

Pharol may not directly or indirectly transfer or assign the PT Option, in whole or in part, nor grant any rights under the PT 
Option, including any security interest in the PT Option or the shares underlying the PT Option, without the consent of Oi. If Pharol 
issues, directly or indirectly, any derivative instrument that is backed by or references Oi’s shares, it shall immediately use all proceeds 
derived directly or indirectly from such derivative instrument to acquire shares pursuant to the exercise of the PT Option. 

On March 31, 2015, we, Pharol and PTIF entered into an amendment to the PT Option Agreement. Under this amendment, 
(1) Pharol will be permitted to assign the PT Option to a third party provided that such assignment involves at least one-quarter of Oi’s 
shares subject to the PT Option, and (2) Pharol has granted Oi a right of first refusal exercisable prior to any such assignment. This 
amendment does not affect the agreement of Pharol not to grant any rights under the PT Option, including any security interest in the 
PT Option or the shares underlying the PT Option, without the consent of Oi, or the requirement that Pharol use all proceeds derived 
directly or indirectly from the issuance of any derivative instrument that is backed by or references Oi’s shares to acquire shares 
pursuant to the exercise of the PT Option. 

The effectiveness of the amendment to the PT Option Agreement was subject to (1) the authorization of the amended terms by the 

CVM, and (2) the approval of the amendment to the PT Option Agreement by a general meeting of Oi’s shareholders at which Oi’s 
common and preferred shareholders will be entitled to vote. However, in December 2015, the CVM collegiate declined to authorize the 
amended terms, as a result of which this amendment has no effect.

Terms of Commitment Agreement 

On March 31, 2015, we and Pharol entered into an amendment to the Terms of Commitment Agreement. The Terms of 

Commitment Agreement, as amended, will remain in effect until the integration of the shareholder bases of Oi and Pharol pursuant to a 
legally permissible structure, which we refer to as the Integration Transaction, has been fully completed, including in respect of any 
shares of Oi that may be acquired by Pharol during the term of the PT Option. 

Under the Terms of Commitment Agreement, we and Pharol each agreed: 

•

•

•

to use our respective best efforts and to take all reasonable measures to also implement the listing of Oi’s shares (or 
securities backed by Oi’s shares or Oi’s successor in case of a corporate reorganization) on the regulated market of Euronext 
Lisbon concurrently with the migration of Oi to the Novo Mercado segment of the B3, which we refer to as the migration, 
provided that in the event that it is not possible for any reason beyond the control of the parties for these listings to occur 
prior to or concurrently with the approval of the migration, they will use their best efforts and to take all reasonable measures 
to implement these listings as soon as possible following the migration. 

to perform all acts, provide any required information, prepare all necessary documentation and to present and duly file all 
necessary filings before all appropriate governmental bodies and authorities so as to implement the listing on the regulated 
market of Euronext Lisbon and Integration Transaction as soon as possible. 

to undertake to perform all necessary acts to implement the Integration Transaction relating to all shares of Oi held by Pharol 
as of March 31, 2015 or that Pharol shall come to hold for so long as the Terms of Commitment Agreement is in force, 
including, but not limited to: 

➣ preparing and filing any prospectuses, including for admission to trading, registration statements or other documents 
with the CVM, the CMVM, Euronext Lisbon and the SEC by Pharol and/or Oi (or Oi’s successor in case of a 
corporate reorganization), as the case may be, including the preparation of audited and unaudited financial statements 
required by the rules of such government authorities, and 

➣ engaging independent auditors, independent financial institutions or other experts to prepare financial statements, 

valuation reports and/or other necessary reports or documents and to use best efforts to cause such experts to consent 
to the inclusion their reports or other documents in the prospectuses, registration statements or other documents to be 
filed with CVM, CMVM, Euronext Lisbon and the SEC. 

In addition, under the Terms of Commitment Agreement we agreed to attend any general meetings of the shareholders of Pharol 

convened for the purposes of deliberating on the acts and authorizations required for the Integration Transaction, whether through a 
reduction of the share capital of Pharol, pursuant to the alternative structure under analysis described in the Information Statement 
issued by Pharol, dated August 13, 2014, or through another legally permissible alternative structure, and to vote in favor of the 
approval of these acts and authorizations, to the extent our legitimate interests are preserved. 

The obligations assumed by Oi and Pharol described above apply equally in the event the Integration Transaction continues in 

respect of any of Oi’s shares that Pharol may receive upon exercise of the PT Option. 

Related Party Transactions 

The following summarizes the material transactions that we have engaged in with Oi’s principal shareholders and their affiliates 

since January 1, 2016. 

Under the Brazilian Corporate Law, Oi’s directors, their alternates and Oi’s executive officers cannot vote on any matter in which 
they have a conflict of interest and such transactions can only be approved on reasonable and fair terms and conditions that are no more 
favorable than the terms and conditions prevailing in the market or offered by third parties. However, if one of Oi’s directors is absent 
from a meeting of Oi’s board of directors, that director’s alternate may vote even if that director has a conflict of interest, unless the 
alternate director shares that conflict of interest or has another conflict of interest.

Transactions with AIX 

Companhia AIX de Participações S.A., in which we own 50% of the outstanding share capital, renders services to us relating to 

the rental of ducts for transmission of traffic originated outside our local network in Region I of Brazil. During 2017 and 2016, our total 
consolidated expenses for services rendered by AIX amounted to R$28 million and R$26 million, respectively. 

Transactions with Hispamar 

We own 19% of the capital stock of Hispamar. We lease transponders on the Amazonas 3 satellite from Hispamar, which we use 

to provide voice and data services. During 2017 and 2016, our total consolidated expenses under the lease agreements amounted to 
R$185 million and R$221 million, respectively. As of December 31, 2017 and 2016, we had accounts payable to Hispamar of 
R$62 million and R$79 million, respectively. 

ITEM 8.

FINANCIAL INFORMATION 

Consolidated Statements and Other Financial Information 

Reference is made to Item 19 for a list of all financial statements filed as part of this annual report. 

Legal Proceedings 

We are a party to certain legal proceedings arising in the normal course of business, including civil, administrative, tax, social 
security, labor, government and arbitration proceedings. We classify our risk of loss in legal proceedings as “remote,” “possible” or 
“probable,” and we only record provisions for reasonably estimable probable losses, as determined by our management. 

As a result of the RJ Proceedings, we have applied ASC 852 in preparing our consolidated financial statements. ASC 852 requires 
that financial statements separately disclose and distinguish transactions and events that are directly associated with our reorganization 
from the transactions and events that are associated with the ongoing operations of our business. Accordingly, our prepetition 
obligations, including certain of our legal contingencies, that may be impacted by the RJ Proceedings based on our assessment of these 
obligations following the guidance of ASC 852 have been classified on our balance sheet as “Liabilities subject to compromise.” 
Prepetition liabilities subject to compromise are required to be reported at the amount allowed as a claim by the RJ Court, regardless of 
whether they may be settled for lesser amounts and remain subject to future adjustments based on negotiated settlements with claimants, 
actions of the RJ Court or other events. For more information about the impact of the RJ Proceedings on our legal proceedings, see 
“Item 5. Operating and Financial Review and Prospects—Liabilities Subject to Compromise—Labor Contingencies,” “—Civil 
Contingencies – ANATEL,” and “—Civil Contingencies – Other Claims” and note 28 to our consolidated financial statements included 
in this annual report. 

As of December 31, 2017 and 2016, the total estimated amount in controversy for those proceedings not subject to the RJ Plan in 

respect of which the risk of loss was deemed probable or possible totaled approximately R$29,535 million and R$29,077 million, 
respectively, and we had established provisions of $1,368 million and R$1,129 million, respectively, relating to these proceedings. Our 
provisions for legal contingencies are subject to monthly monetary adjustments. For a detailed description of our provisions for 
contingencies, see note 18 to our consolidated financial statements included in this annual report. 

In certain instances, we are required to make judicial deposits or post financial guarantees with the applicable judicial bodies. As 

of December 31, 2017 and 2016, we had made judicial deposits in the aggregate amount of R$9,313 million and R$9,366 million, 
respectively, and obtained financial guarantees from third parties in the aggregate amount of R$14,847 million and R$14,556 million, 
respectively. During 2017 and 2016, we paid fees in the aggregate amount of R$298 million and R$306 million, respectively, to the 
financial institutions from which we had obtained these guarantees, and as of each of December 31, 2017 and 2016, we had pledged 
1,811,755 of Oi’s preferred shares, representing 1.15% of our outstanding share capital, as security for one of these financial 
guarantees.

Tax Proceedings Relating to Oi S.A. and Our Brazilian Operations 

As of December 31, 2017 and 2016, the total estimated contingency in connection with tax proceedings against us in respect of 

which the risk of loss was deemed probable or possible totaled R$26,835 million and R$26,534 million, respectively, and we had 
recorded provisions of R$660 million and R$576 million, respectively, relating to these proceedings. In accordance with Brazilian law, 
our tax contingencies are not subject to the RJ Plan. 

The Brazilian corporate tax system is complex, and we are currently involved in tax proceedings regarding, and have filed claims 
to avoid payment of, certain taxes that we believe are unconstitutional. These tax contingencies, which relate primarily to value-added 
tax, service tax and taxes on revenue, are described in detail in note 18 to our consolidated financial statements included in this annual 
report. We record provisions for probable losses in connection with these claims based on an analysis of potential results, assuming a 
combination of litigation and settlement strategies. We currently do not believe that the proceedings that we consider as probable losses, 
if decided against us, will have a material adverse effect on our financial position. It is possible, however, that our future results of 
operations could be materially affected by changes in our assumptions and the effectiveness of our strategies with respect to these 
proceedings. 

Value-Added State Taxes (ICMS) 

Under the regulations governing the ICMS, in effect in all Brazilian states, telecommunications companies must pay ICMS on 

every transaction involving the sale of telecommunications services they provide. We may record ICMS credits for each of our 
purchases of operational assets. The ICMS regulations allow us to apply the credits we have recorded for the purchase of operational 
assets to reduce the ICMS amounts we must pay when we sell our services. 

We have received various tax assessments challenging the amount of tax credits that we recorded to offset the ICMS amounts we 

owed. Most of the tax assessments are based on two main issues: (1) whether ICMS is due on those services subject to the Local 
Service Tax (Imposto Sobre Serviços de Qualquer Natureza), or ISS; and (2) whether some of the assets we have purchased are related 
to the telecommunications services provided, and, therefore, eligible for an ICMS tax credit. A small part of the assessments that are 
considered to have a probable risk of loss are related to: (1) whether certain revenues are subject to ICMS tax or ISS tax; (2) offset and 
usage of tax credits on the purchase of goods and other materials, including those necessary to maintain the network; and 
(3) assessments related to non-compliance with certain ancillary (non-monetary) obligations. 

As of December 31, 2017 and 2016, we deemed the risk of loss as possible with respect to approximately R$11,730 million and 

R$10,983 million, respectively, of these assessments and had not recorded any provisions in respect of these assessments. As of 
December 31, 2017 and 2016, we had recorded provisions in the amount of R$539 million and R$405 million, respectively, for those 
assessments in respect of which we deemed the risk of loss as probable. 

Local Service Tax (ISS) 

We have received various tax assessments claiming that we owe ISS taxes on supplementary services. We have challenged these 

assessments on the basis that ISS taxes should not be applied to supplementary services (such as, among others things, equipment 
leasing and technical and administrative services) provided by telecommunications service providers, because these services do not 
clearly fit into the definition of “telecommunications services.” 

As of December 31, 2017 and 2016, we deemed the risk of loss as possible with respect to approximately R$3,388 million and 

R$3,356 million, respectively, of these assessments and had not recorded any provisions in respect of these assessments. As of 
December 31, 2017 and 2016, we had recorded provisions in the amount of R$73 million and R$67 million, respectively, for those 
assessments in respect of which we deemed the risk of loss as probable.

FUST and FUNTTEL 

The FUST is a fund that was established to promote the expansion of telecommunications services to non-commercially viable 
users. The FUNTTEL was established to finance telecommunications technology research. We are required to make contributions to the 
FUST and the FUNTTEL. Due to a change by ANATEL in the basis for calculation of our contributions to the FUST and the 
FUNTTEL, we made provisions for additional contributions to the FUST and TNL made provisions for additional contributions to the 
FUST and the FUNTTEL. With respect to the calculation of the contribution to the FUST, the Brazilian Association of Fixed-Line 
Companies (Associação Brasileira das Empresas de Telefonia Fixa) of which we are members, filed a lawsuit to request a review of the 
applicable legislation. 

As of December 31, 2017 and 2016, we deemed the risk of loss as possible with respect to approximately R$4,553 million and 

R$3,639 million, respectively, of these assessments and had not recorded any provisions in respect of these assessments. 

Contributions to the INSS 

Pursuant to Brazilian social security legislation, companies must pay contributions to the National Social Security Institute 
(Instituto Nacional do Seguro Social), or INSS, based on their payroll. In the case of outsourced services, the contracting parties must, 
in certain circumstances, withhold the social contribution due from the third-party service providers and pay the retained amounts to the 
INSS. In other cases, the parties are jointly and severally liable for contributions to the INSS. Assessments have been filed against us 
primarily relating to claims regarding joint and several liability and claims regarding the percentage to be used to calculate workers’ 
compensation benefits and other amounts subject to social security tax. 

As of December 31, 2017 and 2016, we deemed the risk of loss as possible with respect to approximately R$574 million and 
R$1,074 million, respectively, of these assessments. As of December 31, 2017 and 2016, we had recorded provisions of R$20 million 
and R$31 million, respectively, for those assessments in respect of which we deemed the risk of loss as probable. 

PIS and COFINS 

In 2006, the Brazilian federal tax authorities filed a claim in the amount of R$1,026 million related to the basis for the calculation 

of PIS/COFINS. In 2007, TNL obtained a partially favorable decision in a lower court that reduced the amount of this claim to 
R$585 million. Both TNL and the Brazilian federal tax authorities filed appeals, with respect to which decisions are pending. As of 
December 31, 2017 and 2016, we deemed the risk of loss as possible with respect to approximately R$2,278 million and R$3,362 
million, respectively, of these assessments and had not recorded any provisions in respect of this claim. 

Other Tax Claims 

There are various federal taxes that have been assessed against us, largely relating to (1) assessments of taxes against our company 

that we do not believe are due and which we are contesting, and (2) our use of tax credits to offset certain federal taxes, which the 
federal tax authorities are contesting. 

As of December 31, 2017 and 2016, we deemed the risk of loss as possible with respect to approximately R$3,653 million and 
R$3,532 million, respectively, of these assessments. As December 31, 2017 and 2016, we had recorded provisions in the amount of 
R$27 million and R$71 million, respectively, for those assessments in respect of which we deemed the risk of loss as probable. 

Civil Claims Relating to Oi S.A. and Our Brazilian Operations 

As of December 31, 2017 and 2016, the total estimated contingency in connection with civil claims against us not subject to the 
RJ Plan in respect of which the risk of loss was deemed probable or possible, totaled R$203 million and R$185 million, respectively, 
and we had recorded provisions of R$11 million and R$10 million, respectively, relating to these proceedings. 

As a result of the commencement of the RJ Proceedings on June 20, 2016, all outstanding civil claims against the RJ Debtors as of 

that date became subject to compromise under our RJ Proceedings. As of December 31, 2017 and 2016, the aggregate amount of the 
contingencies for civil claims (other than claims of ANATEL) recognized by the RJ Court was R$2,929 million and R$3,096 million, 
respectively. 

Under the RJ Plan, unsecured civil claims against the RJ Debtors were classified as Class III and IV claims. For more information 

about these claims and related recoveries under the RJ Plan, see “Item 5. Operating and Financial Review and Prospects—Liabilities 
Subject to Compromise—Civil Contingencies – Other Claims” and “—Civil Contingencies – ANATEL.”

Administrative Proceedings 

On an almost weekly basis, we receive inquiries from ANATEL requiring information from us on our compliance with the various 
service obligations imposed on us by our concession agreements. If we are unable to respond satisfactorily to those inquiries or comply 
with our service obligations under our concession agreements, ANATEL may commence administrative proceedings in connection with 
such noncompliance. We have received numerous notices of commencement of administrative proceedings from ANATEL, mostly due 
to our inability to achieve certain targets established in the General Plan on Quality Goals and the General Plan on Universal Service 
Goals.

At the time that ANATEL notifies us it believes that we have failed to comply with our obligations, we evaluate the claim and, 

based on our assessment of the probability of loss relating to that claim, may establish a provision. We vigorously contest a substantial 
number of the assessments made against us. As a result of the commencement of the RJ Proceedings, our contingencies related to 
claims of ANATEL were reclassified liabilities subject to compromise and were measure as required by ASC 852. As of December 31, 
2017 our prepetition liabilities subject to compromise included R$9,334 million related with claims of ANATEL. By operation of the 
RJ Plan and the Brazilian Confirmation Order (provided that no stay or appeal of the Brazilian Confirmation Order results in a change 
of the Brazilian Confirmation Date), the claim for these contingent obligations has been novated and discharged under Brazilian law 
and ANATEL is entitled only to receive the recovery set forth in the RJ Plan in exchange for these contingent claims in accordance with 
the terms and conditions of the RJ Plan. For more information regarding the recoveries to which ANATEL is entitled under the RJ Plan, 
see “Item 5 Operating and Financial Review and Prospects—Liabilities Subject to Compromise—Civil Contingencies – ANATEL.” 

Brazilian Antitrust Proceedings 

We are subject to administrative proceedings and preliminary investigations conducted by the Brazilian antitrust authorities with 
respect to potential violations of the Brazilian antitrust law. Such investigations may result in penalties, including fines. During 2016, 
2017 and 2018 to date, no fines or penalties have been levied against us. We deemed the risk of loss as possible that we will be fined in 
one or more of such proceedings and have not recorded any provisions for those claims. 

Financial Interest Agreements (PEX and PCT) 

Prior to the privatization of Telebrás, users of fixed-line telephony services in Brazil were required to purchase the right to use 
fixed telephone lines. These purchases could be made through two types of financial interest agreements: (1) Plan of Expansion (Plano 
de Expansão), or PEX, contracts; and (2) Community Telephone Programs (Planta Comunitária de Telefonia), or PCT, contracts. 
Under PEX contracts, customers who purchased a telephone line acquired the right subscribe for a number of a telephone company’s 
shares. Under the PCT program, users who purchased a telephone line acquired a participation in an association formed by a local 
community that subcontracted the construction or expansion of necessary infrastructure, which was then sold to the telephone company, 
in exchange for shares of the company. The number of shares to be issued to each user was determined based on a formula that divided 
the contract value by the book value of the shares. 

We are a defendant in several claims filed by users of telephone lines in the State of Rio Grande do Sul. Prior to our acquisition of 
control of CRT in July 2000, CRT entered into PEX contracts with its fixed-line subscribers. Beginning in June 1997, certain of CRT’s 
fixed-line subscribers began to file suits in which they claimed that the calculation used by CRT to arrive at the number of shares to be 
issued pursuant to the financial interest agreements was incorrect and resulted in the claimants receiving too few shares. 

In addition, as successor to various companies we acquired in the privatization of Telebrás and which were subsequently merged 

into our company, we are subject to various civil claims filed by PCT participants who also disagree with the value of their shares in 
those companies and who seek to recover the amounts they invested. 

In 2009, two court decisions significantly changed the assumptions underlying our estimate of the potential losses relating to these 

suits. In March 2009, the Brazilian Supreme Court published a decision ruling that the financial interest agreements are subject to the 
twenty-year statute of limitations prescribed by the Brazilian Civil Code, as opposed to the three-year statute of limitations prescribed 
by the Brazilian Corporate Law. This decision increased the likelihood of an unfavorable outcome in a greater number of these pending 
cases than previously anticipated. Also in March 2009, the Superior Court of Justice ruled that the number of shares to be issued must 
be calculated using the book value of the shares listed on company’s balance sheet at the end of the first month in which the shares were 
issued. 

As of December 31, 2017 and 2016, we had recorded provisions in the amount of R$1,575 million and R$1,617 million, 

respectively, for those claims in respect of which we deemed the risk of loss as probable.

Customer Service Centers 

We are a defendant in 49 civil class actions filed by the Attorney General of the National Treasury jointly with certain consumer 
agencies demanding the re-opening of customer service centers. The lower courts have rendered decisions in all of these proceedings, 
some of which have been unfavorable to us. All of these proceedings are currently under appeal. As of December 31, 2017 and 2016, 
we had recorded provisions in the amount of R$9.7 million and R$3.5 million, respectively, for those claims in respect of which we 
deemed the risk of loss as probable. 

Customer Service 

We are a defendant in a civil class action lawsuit filed by the Federal Prosecutor’s Office (Ministério Público Federal) seeking 

recovery for alleged collective moral damages caused by TNL’s alleged non-compliance with the Customer Service (Serviço de 
Atendimento ao Consumidor – SAC) regulations established by the Ministry of Justice (Ministério da Justiça). TNL presented its 
defense and asked for a change of venue to federal court in Rio de Janeiro, where we are headquartered. Other defendants have been 
named and await service of process. The amount involved in this action is R$300 million. As a result of the corporate reorganization, 
we have succeeded to TNL’s position as a defendant in this action. As of December 31, 2017 and 2016, we deemed the risk of loss as 
possible with respect to these lawsuits and had not made any provisions with respect to this action since it was awaiting the court’s 
initial decision. 

Special Civil Court Proceedings 

We are party to proceedings in special civil courts relating to customer claims in connection with our basic subscription services. 

The value of any individual claim does not exceed 40 minimum wages. As of December 31, 2017 and 2016, we had recorded provisions 
in the amount of R$261 million and R$354 million, respectively, for these claims in respect of which we deemed the risk of loss as 
probable. 

Other Claims 

We are defendants in various claims involving contract termination, indemnification of former suppliers and contractors, review of 
contractual conditions due to economic stabilization plans and breach of contract. As of December 31, 2017 and 2016, we had recorded 
provisions in the amount of R$884 million and R$800 million, respectively, in respect of these claims. 

Labor Claims Relating to Oi S.A. and Our Brazilian Operations 

We are a party to a large number of labor claims arising out of the ordinary course of our businesses. We do not believe any of 
these claims, individually or in the aggregate would have a material effect on our business, financial condition or results of operations if 
such claims are decided against us. These proceedings generally involve claims for: (1) risk premium payments sought by employees 
working in dangerous conditions; (2) wage parity claims seeking equal pay among employees who do the same kind of work, within a 
given period of time, and have the same productivity and technical performance; (3) indemnification payments for, among other things, 
work accidents, occupational injuries, employment stability, child care allowances and achievement of productivity standards set forth 
in our collective bargaining agreements; (4) overtime wages; and (5) joint liability allegations by employees of third-party service 
providers. 

As of December 31, 2017 and 2016, the total estimated contingency in connection with labor claims against us not subject to the 

RJ Plan in respect of which the risk of loss was deemed probable or possible totaled R$1,547 million and R$1,294 million, respectively, 
and we had recorded provisions of R$697 million and R$543 million, respectively, relating to these proceedings. 

As a result of the commencement of the RJ Proceedings on June 20, 2016, all outstanding labor claims against the RJ Debtors as 
of that date became subject to compromise under our RJ Proceedings. As of December 31, 2017 and 2016, the aggregate amount of the 
contingencies for labor claims recognized by the RJ Court was R$899 million and R$752 million, respectively. 

Under the RJ Plan, labor claims were classified as Class I claims. For more information about these claims and related recoveries 

under the RJ Plan, see “Item 5. Operating and Financial Review and Prospects—Liabilities Subject to Compromise—Labor 
Contingencies.”

Legal Proceedings Relating to Our Interest in Africatel 

On September 16, 2014, Africatel KG received a letter from Samba Luxco in which Samba Luxco claimed that Oi’s acquisition of 

PT Portugal in May 2014 was deemed a change of control of Pharol under the Africatel shareholders’ agreement, and that this change 
of control entitled Samba Luxco to exercise a put right under the Africatel shareholders’ agreement at the fair market equity value of 
Samba Luxco’s shares of Africatel BV. In the letter, Samba Luxco purported to exercise the alleged put right and thereby require 
Africatel KG to acquire Samba Luxco’s shares in Africatel BV. 

On November 12, 2014, the International Court of Arbitration of the International Chamber of Commerce notified Africatel KG 

that Samba Luxco had commenced arbitral proceedings against Africatel KG to enforce its purported exercise of the put right or, in the 
alternative, certain ancillary rights and claims. Africatel KG presented its answer to Samba Luxco’s request for arbitration on 
December 15, 2014. The arbitral tribunal was constituted on March 12, 2015 and held a first management conference in London on 
May 8, 2015. 

On July 22, 2015, Samba Luxco submitted its Statement of Claim, and on October 9, 2015, Pharol and Africatel KG submitted 

their Statement of Defence. On January 25, 2016, Samba Luxco submitted its Reply and, on March 14, 2016, Pharol and Africatel KG 
submitted their Rejoinder. On April 25, 2016, the parties executed a memorandum of understanding following which they agreed to 
defer a hearing on the merits of the arbitral proceedings. 

On June 16, 2016, PT Participações, Africatel KG and Africatel BV entered into a series of agreements with Samba Luxco with 

the primary purpose of settling the arbitral proceedings, including an amendment to the Africatel shareholders agreement and the 
Settlement Agreement, under which Samba Luxco agreed, upon the implementation of the Settlement Agreement: (1) to terminate the 
ongoing arbitration proceeding and release our subsidiaries from all past and present claims related to alleged breaches of the Africatel 
shareholders agreement asserted in the arbitration proceeding, (2) to waive certain approval rights it had under the Africatel 
shareholders agreement, and (3) to transfer 11,000 shares of Africatel BV to Africatel BV, resulting in a decline of Samba Luxco’s 
stake in Africatel BV from 25% to 14%. In exchange, Africatel BV agreed to transfer to Samba Luxco its stake in the capital of Mobile 
Telecommunications Limited, a the telecommunications operator in Namibia, or MTC, which represented approximately 34% of the 
share capital of MTC. 

On January 31, 2017, the transactions provided for in the Settlement Agreement were completed. As a consequence, on 
February 2, 2017, the parties to the arbitral proceedings informed the arbitral tribunal of the full and final settlement of their dispute. 
Samba Luxco has withdrawn all claims brought in the arbitration and released us from all past and present claims relating to alleged 
breaches of the Africatel shareholders’ agreement. 

Legal Proceedings Relating to Our Interest in Unitel 

On October 13, 2015, PT Ventures initiated an arbitration proceeding against the other Unitel shareholders as a result of the 

violation by those shareholders of a variety of provisions of the Unitel shareholders’ agreement and Angolan law, including the 
provisions entitling PT Ventures to nominate the majority of the members of the board of directors of Unitel and its chief executive 
officer and the fact that the other Unitel shareholders caused Unitel not to pay dividends owed to PT Ventures and withheld information 
and clarifications on such payment. 

On March 14, 2016, the other shareholders of Unitel initiated an arbitration proceeding against PT Ventures, claiming that 

Pharol’s sale of a minority interest in Africatel to our company in May 2014 constituted a breach of the Unitel shareholders’ agreement. 
PT Ventures disputes this interpretation of the relevant provisions of the Unitel shareholders’ agreement, and we believe that the 
relevant provisions of the Unitel shareholders’ agreement apply only to a transfer of Unitel shares by PT Ventures itself.

The arbitral tribunal was constituted on April 14, 2016. On May 19, 2016, the arbitration proceeding against PT Ventures initiated 
by the other Unitel shareholders was consolidated with the arbitration initiated by PT Ventures. On October 14, 2016, PT Ventures filed 
its Statement of Claim in the arbitration and the Unitel shareholders presented their statement of defense and counterclaim on 
February 28, 2017. A hearing in the arbitration was held from February 7 to 16, 2018, where each party presented its arguments and the 
factual witnesses and experts from each side were heard. We intend to continue to vigorously defend these proceedings. As of the date 
of the hearing, PT Ventures’s financial expert assessed PT Ventures’s claim at US$ 2,988 million (as of December 2014), plus interest 
since December 2014. 

Legal Proceedings Relating to Our Financial Restructuring 

PTIF Avoidance Proceedings 

On March 16, 2016, Capricorn Capital Ltd., or Capricorn, commenced actions against Oi, Oi Mobile, Oi Coop, PTIF, as well as 

several directors of Oi Coop and PTIF seeking the avoidance of certain loans that PTIF made to Oi Coop. In this action, Capricorn 
seeks to hold PTIF, Oi Coop and Oi, as well as the individual defendants, liable for damages that Capricorn has claimed that it suffered 
as a consequence of transactions that Capricorn alleges prejudiced its interests as holders of bonds issued by PTIF. 

On March 30, 2016, Capricorn commenced interim relief proceedings (kort geding) in which Capricorn demanded an injunction 
preventing Oi Coop from on-lending monies to any of the RJ Debtors for so long as Oi Coop has any outstanding obligations under its 
loan to PTIF. The Dutch District Court denied Capricorn’s demand for an injunction on May 2, 2016. This decision was affirmed by the 
Dutch Court of Appeals on July 19, 2016. 

On November 14, 2017, the Dutch District Court held a hearing on Capricorn’s claims. On March 21, 2017, the Dutch District 
Court rendered a judgment denying Capricorn’s claims against the directors of Oi Coop and PTIF. The Court held that the no-action 
clause in the Trust Deed governing the bonds issued by PTIF precluded Capricorn from advancing claims against these directors. 
Although Oi did not appear in these proceedings, it appears the Dutch District Court also found that the right under the Trust Deed 
governing the bonds issued by PTIF to bring proceedings against Oi is vested exclusively in the Trustee under the Trust Deed. 

Judicial Reorganization Proceedings 

On June 20, 2016, Oi, together with the other RJ debtors, filed a joint voluntary petition for judicial reorganization pursuant to 

Brazilian Law No. 11,101 of June 9, 2005, or the Brazilian Bankruptcy Law, with the 7th Commercial Court of the Judicial District of 
the State Capital of Rio de Janeiro, or the RJ Court, pursuant an urgent measure approved by our board of directors. 

On December 20, 2017, the RJ Plan was approved by a significant majority of creditors of each class present at the GCM. On 

January 8, 2018, the RJ Court entered the Brazilian Confirmation Order, ratifying and confirming the RJ Plan, but modifying certain 
provisions of the RJ Plan. The Brazilian Confirmation Order was published in the Official Gazette of the State of Rio de Janeiro on 
February 5, 2018. 

For more information regarding the RJ Proceedings, see “Item 4. Information on the Company—Our Recent History and 

Development—Our Judicial Reorganization Proceedings.” 

Recognition Proceedings in the United States 

On June 22, 2016, the U.S. Bankruptcy Court entered an order granting the provisional relief requested by the Chapter 15 Debtors 

in their cases that were filed on June 21, 2016 under Chapter 15 of the United States Bankruptcy Code. On July 22, 2016, the U.S. 
Bankruptcy Court granted the U.S. Recognition Order. 

On July 7, 2017, Mr. J.R. Berkenbosch, in his capacity as Oi Coop’s bankruptcy trustee in The Netherlands, filed with the U.S. 

Bankruptcy Court a motion seeking modification or termination of the U.S. Recognition Order in respect of Oi Coop and filed a 
competing petition for recognition of the Dutch Bankruptcy Proceeding in respect of Oi Coop as the foreign main proceeding for 
purposes of U.S. law.

On December 4, 2017, the U.S. Bankruptcy Court issued a written opinion, denying Mr. Berkenbosch’s motion and petition in its 

entirety and entered an order to that effect on December 26, 2017. On January 8, 2018, Mr. Berkenbosch filed a notice of appeal with 
the U.S. Bankruptcy Court indicating his intention to appeal the December 4 decision and the December 26 order of the U.S. 
Bankruptcy Court. On January 9, 2018, the IBC also filed a notice of appeal indicating its intention to appeal the December 4 decision 
and the December 26 order of the U.S. Bankruptcy Court. Neither Mr. Berkenbosch nor the IBC has sought a stay of the December 4 
decision and the December 26 order of the U.S. Bankruptcy Court. 

The Chapter 15 Debtors intend to seek entry of an order from the U.S. Bankruptcy Court giving full force and effect to the RJ Plan 

and the Brazilian Confirmation Order in the United States and all other appropriate and necessary measures in order to implement the 
RJ Plan. 

For more information regarding the proceedings of the Chapter 15 Debtors before the U.S. Bankruptcy Court, see “Item 4. 
Information on the Company—Our Recent History and Development—Our Judicial Reorganization Proceedings—Recognition 
Proceedings in the United States.” 

Recognition Proceedings in the United Kingdom 

On June 23, 2016, the High Court of Justice of England and Wales granted the U.K. Recognition Orders. On July 28, 2016, the 

U.K. Recognition Order granted in respect of Oi Mobile was partially modified to lift the suspension on its rights to transfer, encumber 
or otherwise dispose of its assets. 

For more information regarding the proceedings in the United Kingdom relating to the RJ Proceedings, see “Item 4. Information 
on the Company—Our Recent History and Development—Our Judicial Reorganization Proceedings—Recognition Proceedings in the 
United Kingdom.” 

Restructuring of Our Dutch Finance Subsidiaries 

On June 27, 2016, Syzygy, an affiliate of Aurelius, filed a petition for the involuntary bankruptcy of Oi Coop before the Dutch 

District Court, requesting that the Dutch District Court (1) declare Oi Coop in a state of bankruptcy, and (2) declare the bankruptcy of 
Oi Coop a main insolvency proceeding within the meaning of Article 3.1 of the European Insolvency Regulation (EC no. 1346/2000). 
On July 8, 2016, Loomis Sayles Strategic Income Fund also filed a petition for the involuntary bankruptcy of Oi Coop in the Dutch 
District Court making similar requests as those made in the Oi Coop proceeding. On July 11, 2016, a group of beneficial holders of Oi 
Coop bonds filed an involuntary bankruptcy petition against Oi Coop in the Dutch District Court. On July 15, 2016, another group of 
beneficial holders of Oi Coop bonds filed an involuntary bankruptcy petition against Oi Coop in the Dutch District Court. 

On August 9, 2016 Oi Coop filed with the Dutch District Court a petition for a Dutch suspension of payments (verzoekschrift tot 

aanvragen surseance van betaling) proceeding, an insolvency proceeding aimed at facilitating the reorganization, rather than the 
liquidation, of an insolvent debtor by imposing a temporary stay against creditor actions. On August 9, 2016, the Dutch District Court 
granted the request of Oi Coop for the commencement of suspension of payment proceedings. 

On August 22, 2016, Citicorp Trustee Company Limited, or Citicorp, in its capacity as the trustee in respect of the a series of 
bonds issued by PTIF, purportedly acting at the direction of the requisite majority of the holders of these bonds, filed a petition for the 
involuntary bankruptcy of PTIF in the Dutch District Court requesting that the Dutch District Court (1) order the bankruptcy of PTIF, 
and (2) declare the bankruptcy of PTIF a main insolvency proceeding within the meaning of Article 3.1 of the European Insolvency 
Regulation (EC no. 1346/2000) 

On September 30, 2016, PTIF filed with the Dutch District Court a petition for a Dutch suspension of payments proceeding. On 
October 3, 2016, the Dutch District Court granted the request of PTIF for the commencement of suspension of payment proceedings.

On December 1, 2016, both Mr. Berkenbosch for Oi Coop and Mr. Groenewegen for PTIF filed a petition with the Dutch District 
Court requesting that the Oi Coop suspension of payments proceedings and the PTIF suspension of payments proceedings, respectively, 
be withdrawn and advising the Dutch District Court to declare Oi Coop and PTIF bankrupt. Subsequently, on December 23, 2016, the 
IBC filed a petition with the Dutch District Court requesting that the Oi Coop suspension of payments proceeding be withdrawn and 
that Oi Coop be declared bankrupt. On January 4, 2017, Citicorp filed a petition with the Dutch District Court requesting that the PTIF 
suspension of payments proceeding be withdrawn and PTIF be declared bankrupt. 

On February 2, 2017, following hearings to consider these requests on January 12, 2017, the Dutch District Court rendered 

decisions denying each of these requests. 

On February 10, 2017, the IBC and Citicorp appealed the rulings of the Dutch District Court denying their respective requests to 

the Dutch Court of Appeal. 

On April 19, 2017, the Dutch Court of Appeals granted the appeals of the IBC and Citicorp, overturning the Dutch District Court 

decisions and ordering that the suspension of payments proceedings in respect of Oi Coop and PTIF be converted into Dutch
bankruptcy proceedings. The Dutch Court of Appeals further appointed Mr. Berkenbosch as Oi Coop’s bankruptcy trustee in the
Netherlands, and Mr. Groenewegen as PTIF’s bankruptcy trustee in the Netherlands. 

On July 7, 2017, upon certain appeals of the decisions of the Dutch Court of Appeals, the Dutch Supreme Court issued a decision 

affirming the decisions of the Dutch Court of Appeals. 

Oi Coop Avoidance Proceedings 

On May 30, 2017, Mr. Berkenbosch, as Oi Coop’s bankruptcy trustee in the Netherlands, commenced a Dutch Pauliana action on 

behalf of the Dutch bankruptcy estate of Oi Coop against Oi and Oi Mobile in the Dutch District Court seeking repayment of and 
damages in relation to several intercompany loans made by Oi Coop to Oi and Oi Mobile. On July 26, 2017, two funds that are holders 
of bonds issued by Oi Coop filed a request to join these proceedings in their capacity as creditors of Oi Coop and parties-in-interest the 
side of Oi and Oi Mobile. 

On August 16, 2017 and August 23, 2017, Oi and Oi Mobile, respectively, filed motions contesting jurisdiction of the Dutch 

District Courts to hear the claims of Mr. Berkenbosch asserted in these proceedings, which motion remains pending. 

Non-Provisioned Contingencies 

We are defendants in various proceedings with no legal precedent involving network expansion plans, compensation for moral and 

material damages, collections and bidding proceedings, intellectual property and supplementary pension plan, among others, for which 
we deem the risk of loss as possible and have not recorded any provisions. As of December 31, 2017 and 2016, we deemed the risk of 
loss as possible with respect to R$28,167 million and R$27,949 million, respectively, of these proceedings. This amount is based on 
total value of the damages being sought by the plaintiffs; however, the value of some of these claims, cannot be estimated at this time. 
Typically, we believe the value of individual claims to be beyond the merits of the case in question. 

Dividends and Dividend Policy 

The following discussion summarizes the principal provisions of the Brazilian Corporate Law, Oi’s by-laws and the RJ Plan 

relating to the distribution of dividends, including interest attributable to shareholders’ equity. 

Dividend Policy 

Oi’s dividend distribution policy has historically included the distribution of periodic dividends, based on the annual financial 
statements approved by Oi’s board of directors, in accordance with the Brazilian Corporate Law and as set forth in Oi’s by-laws, which 
provide that, in general, a minimum amount of 25% of Oi’s consolidated net profit for each fiscal year, as adjusted for amounts 
allocated to legal and other applicable reserves in accordance with the Brazilian Corporate Law, must be distributed to shareholders. We 
refer to this amount as the mandatory distributable amount. Oi may pay the mandatory distributable amount as dividends, interest 
attributable to shareholders’ equity, which is similar to a dividend but is deductible in calculating income tax obligations, subject to 
certain limitations imposed by law as described in “Item 10. Additional Information—Taxation—Brazilian Tax 
Considerations—Interest on Shareholders’ Equity,” share grants or redemption, capital reduction or other forms that enable the 
distribution of funds to shareholders. Payment of intermediate or interim dividends is also be permitted, subject to market conditions, 
Oi’s then-prevailing financial condition and other factors deemed relevant by Oi’s board of directors. Oi may set off any payment of 
interim dividends against the amount of the mandatory distributable amount to be paid in the year in which the interim dividends are 
paid.

Notwithstanding the above, the RJ Plan provides for a new dividend policy that supersedes the provisions of Oi’s by-laws. Under 

Section 10.1 of the RJ Plan, Oi and the other RJ Debtors are prohibited from declaring or paying dividends, interest on shareholders’ 
equity or other forms of return on capital or making any other payment or distribution on or related to their shares (including any 
payment related to a merger or consolidation) until the sixth anniversary of the date of the Judicial Ratification of the RJ Plan, subject to 
the following exceptions: 

•

•

•

distributions made between the RJ Debtors; 

payments by Oi and the other RJ Debtors to dissenting shareholders, according to applicable law, carried out after the date of 
the Judicial Ratification of the RJ Plan; and 

any distribution made in accordance with the RJ Plan. 

After the sixth anniversary of the date of the Judicial Ratification of the RJ Plan, Oi and the other RJ Debtors will be permitted to 
declare or pay dividends, interest on shareholders’ equity or other forms of return on capital or make any other payment or distribution 
on or related to their shares (including any payment related to a merger or consolidation) if the ratio of Oi’s consolidated net debt 
(defined as Financial Credits, minus Cash Balance, plus the Pre-Petition Credits held by ANATEL (in each case as defined in the RJ 
Plan)) to EBITDA (as defined in the RJ Plan)) is less than or equal to 2 to 1. After the Capitalization of Credits Capital Increase and the 
Cash Capital Increase, Oi and the other RJ Debtors will be permitted to declare or make such payments if the ratio of Oi’s consolidated 
net debt (defined as Financial Credits, minus Cash Balance (in each case as defined in the RJ Plan)) to EBITDA (as defined in the RJ 
Plan) for the fiscal year ended immediately prior to any such declaration or payment is less than or equal to 2 to 1. There shall not be 
any restriction to the distribution of dividends after the full payment of the Financial Credits. The restrictions of the payment of 
dividends and other distributions described in this paragraph are superseded by the same exceptions described in the paragraph above. 

Pursuant to Section 10.2 of the RJ Plan, if at any time any two of Standard & Poor’s, Moody’s and Fitch rate Oi as investment 
grade and no default occurs, the restrictions on distributions imposed by Section 10.1 of the RJ Plan will be suspended. However, if any 
rating agency subsequently cancels or downgrades Oi’s rating, then the suspended restrictions will be reinstated. 

Historical Payment of Dividends 

The following table sets forth the dividends and/or interest attributable to shareholders’ equity paid to holders of Oi’s common 
shares and preferred shares since January 1, 2013 in reais and in U.S. dollars translated from reais at the commercial market selling rate 
in effect as of the payment date.

shares in the total amount of R$0.991(US$0.491) per common and preferred share. 

(3) Represents dividends of R$3.049 (US$1.397) per common and preferred share. 

The mandatory distributable amount of dividends and interest attributable to shareholders’ equity is recognized as a provision at 

the year-end. Any proposed dividends above the mandatory distributable amount are only recognized when duly declared. 

Any holder of record of shares at the time that a dividend is declared by Oi is entitled to receive dividends. Pursuant to the 
Brazilian Corporate Law, Oi is generally required to pay dividends within 60 days after declaring them, unless the shareholders’ 
resolution establishes another payment date, which, in any case, must occur prior to the end of the fiscal year in which the dividend is 
declared.

Distributions of dividends in any year are made: 

•

•

•

first, to the holders of preferred shares, up to the greater non-cumulative amount of: (1) 6.0% per year of the amount 
resulting from Oi’s share capital divided by the number of Oi’s total issued shares, or (2) 3.0% per year of the book value of 
Oi’s shareholders’ equity divided by the number of Oi’s total issued shares, or the Minimum Preferred Dividend; 

then, to the holders of common shares, until the amount distributed in respect of each common share is equal to the amount 
distributed in respect of each preferred share; and 

thereafter, to the common and preferred shareholders on a pro rata basis. 

Under the Brazilian Corporate Law, if the Minimum Preferred Dividend is not paid for a period of three years, holders of preferred 

shares are entitled to full voting rights. As a result of Oi’s failure to pay the Minimum Preferred Dividend for 2014, 2015 and 2016, 
holders of Oi’s preferred shares obtained full voting rights on April 28, 2017, the date that our annual shareholders’ meeting approved 
our financial statements for fiscal year 2016. 

Shareholders have three years to claim dividend distributions made with respect to their shares, as from the date that the 
distribution was approved, after which any unclaimed dividend distributions legally revert to Oi. Oi is not required to readjust any 
amounts of any dividends to be distributed by the inflation rates that occurred during the period counted as of the date of declaration of 
the dividend until its payment date. 

Because Oi’s shares are issued in book-entry form, dividends with respect to any share are automatically credited to the account 

holding such share. Shareholders who are not residents of Brazil must register with the Brazilian Central Bank in order to receive 
dividends, sales proceeds or other amounts with respect to their shares to be eligible to be remitted outside of Brazil. 

The common and preferred shares underlying Oi’s ADSs are held in Brazil by the depositary, which has registered with the 
Brazilian Central Bank as the registered owner of Oi’s common and preferred shares. Payments of cash dividends and distributions, if 
any, will be made in Brazilian currency to the depositary. The depositary will then convert such proceeds into dollars and will cause 
such dollars to be distributed to holders of Oi’s ADSs. As with other types of remittances from Brazil, the Brazilian government may 
impose temporary restrictions on remittances to foreign investors of the proceeds of their investments in Brazil, as it did for 
approximately six months in 1989 and early 1999, and on the conversion of Brazilian currency into foreign currencies, which could 
hinder or prevent the depositary from converting dividends into U.S. dollars and remitting these U.S. dollars abroad. See “Item 3. Key 
Information—Risk Factors—Risks Relating to Oi’s Common Shares, Preferred Shares and ADSs.” 

Taxation of Dividends 

Under the current Brazilian tax law, dividends paid to persons who are not Brazilian residents, including holders of ADSs, are not 
subject to Brazilian withholding tax, except for dividends declared based on profits generated prior to December 31, 1995, which may 
be subject to Brazilian withholding income tax at varying tax rates. Any payment of interest attributable to shareholders’ equity to 
holders of Oi’s common shares or preferred shares or ADSs, whether or not they are Brazilian residents, is subject to Brazilian 
withholding tax at the rate of 15%, except that a 25% withholding tax rate applies if the recipient is a resident of a “tax haven” 
jurisdiction for this purpose. For information regarding Brazilian tax implications of dividends and interest attributable to shareholders’ 
equity, see “Item 10. Additional Information— Taxation—Brazilian Tax Considerations.” 

Holders of Oi’s commons shares, preferred shares or ADSs may also be subject to U.S. federal income taxation on dividends and 

interest attributable to shareholders’ equity. For more information on the U.S. federal tax implications of dividends and interest 
attributable to shareholders’ equity, see “Item 10. Additional Information— Taxation—U.S. Federal Income Tax Considerations.” 

Significant Changes 

Other than as disclosed in this annual report, no significant change has occurred since the date of the audited consolidated

The principal trading market for Oi’s common shares and preferred shares is the B3, where they are traded under the symbols 

“OIBR3” and “OIBR4,” respectively. Oi’s common shares and preferred shares began trading on the B3 on July 10, 1992. On 
November 16, 2001, Oi’s Preferred ADSs began trading on the NYSE under the symbol “BTM.” On November 17, 2009, Oi’s 
Common ADSs began trading on the NYSE under the symbol “BTMC.” On April 9, 2012, the trading symbols for Oi’s Preferred ADSs 
and Common ADSs on the NYSE were changed to “OIBR” and “OIBR.C,” respectively. 

On June 21, 2016, the NYSE determined that Oi’s Preferred ADSs should be suspended immediately from trading and 
commenced procedures to remove Oi’s Preferred ADSs from listing and registration on the NYSE based on the “abnormally low” 
trading price of the Preferred ADSs. On June 23, 2016, the OTC Markets Group, Inc. began publishing quotations for Oi’s Preferred 
ADS in the “pink sheets” under the trading symbol OIBRQ. On July 6, 2016, the NYSE filed a Notification of Removal from Listing 
and/or Registration under Section 12(b) of the Securities Exchange Act of 1934 with the SEC with respect to Oi’s Preferred ADSs and 
the Preferred ADSs were removed from listing and registration on the Exchange on July 18, 2016. Oi’s Common ADSs continue to be 
listed and registered on the NYSE. 

On May 17, 2017, the NYSE provided a notice to Oi stating that Oi was not in compliance with the NYSE’s continued listing 
requirements under the timely filing criteria established in Section 802.01E of the NYSE Listed Company Manual. The NYSE decided 
not to delist Oi’s Common ADSs as a result of this non-compliance and granted an initial six-month extension for Oi to comply with 
such continued listing requirements. On November 21, 2017, the NYSE granted an additional six-month cure period for satisfying the 
continued listing requirements, which will expire on May 17, 2018. Oi has been in contact with the NYSE regularly. As a result of the 
filing of this annual report, Oi believes it has cured the delinquency and is in compliance with the NYSE continued listing requirements. 

Oi has registered its Common ADSs and Preferred ADSs with the SEC pursuant to the Exchange Act. On December 31, 2017, 
there were 16.472.915 Common ADSs, representing 82.364.575 common shares, or 15.85% of Oi’s outstanding common shares, and 
43.337.848 Preferred ADSs outstanding, representing 43.337.848 preferred shares, or 27.80% of Oi’s outstanding preferred shares.

Regulation of Brazilian Securities Markets 

The Brazilian securities markets are regulated by the CVM, which has regulatory authority over the stock exchanges and the 
securities markets generally, the National Monetary Council and the Brazilian Central Bank, which has, among other powers, licensing 
authority over brokerage firms and which regulates foreign investment and foreign exchange transactions. The Brazilian securities 
markets are governed by (1) Law No. 6,385, as amended and supplemented, which is the principal law governing the Brazilian 
securities markets, (2) the Brazilian Corporate Law, and (3) the regulations issued by the CVM, the National Monetary Council and the 
Brazilian Central Bank. 

These laws and regulations provide for, among other things, disclosure requirements applicable to issuers of publicly traded 

securities, restrictions on insider trading (including criminal sanctions under the Brazilian Penal Code) and price manipulation, 
protection of minority shareholders and disclosure of transactions in a company’s securities by its insiders, including directors, officers 
and major shareholders. They also provide for the licensing and oversight of brokerage firms and the governance of Brazilian stock 
exchanges. 

However, the Brazilian securities markets are not as highly regulated or supervised as U.S. securities markets or securities markets 

in some other jurisdictions. In addition, rules and policies against self-dealing or for preserving shareholder interests may be less well-
defined and enforced in Brazil than in the United States, which may put holders of Oi’s preferred shares and the ADSs at a 
disadvantage. Finally, corporate disclosures also may be less complete than for public companies in the United States and certain other 
jurisdictions.

Under the Brazilian Corporate Law, a company is either publicly held (companhia aberta), as Oi is, or privately held (companhia 

fechada). All publicly held companies are registered with the CVM and are subject to reporting and regulatory requirements. A 
company registered with CVM may have its securities traded either on the B3 or in the Brazilian over-the-counter market. Shares of 
companies, such as Oi, that are listed on the B3 may not simultaneously trade on the Brazilian over-the-counter market. The shares of a 
publicly held company may also be traded privately, subject to certain limitations. 

The Brazilian over-the-counter market consists of direct trades between individuals in which a financial institution registered with 

the CVM serves as intermediary. No special application, other than registration with the CVM, is necessary for securities of a public 
company to be traded in this market. The CVM requires that it be given notice of all trades carried out in the Brazilian over-the-counter 
market by the respective intermediaries. 

Brazilian regulations also require that any person or group of persons representing the same interest that has directly or indirectly 

carried out a material transaction or set of transactions by which the equity interest held by such person or group of persons surpasses or 
falls below the thresholds of 5%, or any 5% multiple thereof, of a type or class of shares of a publicly traded company must provide 
such publicly traded company with information on such transaction and its purpose, and such company must transmit this information 
to the CVM. If this acquisition causes a change in the control of the company or in the administrative structure of the company, or if 
this acquisition triggers the obligation to make a public offering in accordance with CVM Instruction No. 361, as amended, then the 
acquirer must disclose this information to the applicable stock exchanges and the same means of communication usually adopted by the 
company. 

Trading on the B3 

Overview of the B3 

In 2000, the São Paulo Stock Exchange (Bolsa de Valores de São Paulo S.A. – BVSP), or the BOVESPA, was reorganized through 

the execution of memoranda of understanding by the Brazilian stock exchanges. Following this reorganization, the BOVESPA was a 
non-profit entity owned by its member brokerage firms and trading on the BOVESPA was limited to these member brokerage firms and 
a limited number of authorized nonmembers. Under the memoranda, all securities are now traded only on the BOVESPA, with the 
exception of electronically traded public debt securities and privatization auctions, which are traded on the Rio de Janeiro Stock 
Exchange. 

In August 2007, the BOVESPA underwent a corporate restructuring that resulted in the creation of BOVESPA Holding S.A., a 

public corporation, whose wholly-owned subsidiaries were (1) the BOVESPA, which is responsible for the operations of the stock 
exchange and the organized over-the-counter markets, and (2) the Brazilian Settlement and Custodial Company (Companhia Brasileira 
de Liquidação e Custódia), or CBLC, which is responsible for settlement, clearing and depositary services. In the corporate 
restructuring, all holders of membership certificates of the BOVESPA and of shares of CBLC became shareholders of BOVESPA 
Holding S.A. As a result of the corporate restructuring, access to the trading and other services rendered by the BOVESPA is not 
conditioned on stock ownership in BOVESPA Holding S.A. 

In May 2008, the BOVESPA merged with the Commodities and Futures Exchange (Bolsa de Mercadorias & Futuros) to form the 
BM&FBOVESPA. In November 2008, the CBLC merged with the BM&FBOVESPA. As a result, the BM&FBOVESPA now performs 
its own settlement, clearing and depositary services. In March 2017, BM&FBOVESPA merged with Cetip S.A. – Mercados 
Organizados, a settlement and clearing house in Brazil to form the B3 S.A. – Brasil, Bolsa, Balcão. 

Trading and Settlement 

Trading of equity securities on the B3 is conducted through an electronic trading system called Megabolsa every business day, 

typically from 10:00 a.m. to 5:00 p.m., São Paulo time. During certain months, however, to account for daylight saving time in Brazil 
and more closely align with trading hours in the United States, trading hours on the B3 are extended by one hour to 6:00 p.m., São 
Paulo time. When trading ends at 5:00 p.m. São Paulo time, trading of equity securities on the B3 is also conducted after market 
between 5:25 p.m. and 6:00 p.m., São Paulo time, in an after-market system connected to both traditional brokerage firms and 
brokerage firms operating on the internet. This after-market trading is subject to regulatory limits on price volatility of securities and on 
the volume of shares traded by investors operating on the internet. When trading ends at 5:00 p.m. São Paulo time, there is no after 
market trading.

Since March 2003, market making activities have been allowed on the B3. As of the date of this annual report, Credit Suisse 
(Brasil) S.A. Corretora de Títulos e Valores Mobiliários acts as market maker of Oi’s common shares and preferred shares on the B3. 
Trading in securities listed on the B3 may be effected off the exchange in the unorganized over-the-counter market under certain 
circumstances, although such trading is very limited. 

The trading of securities of a company on the B3 is automatically suspended when a Company announces a material event. It is 

also recommended that the company simultaneously make a request to suspend trading in any international stock exchange in which its 
securities are traded. The CVM and the B3 have discretionary authority to suspend trading in shares of a particular issuer, based on or 
due to a belief that, among other reasons, a company has provided inadequate information regarding a material event or has provided 
inadequate responses to inquiries by the CVM or the B3. 

In order to reduce volatility, the B3 has adopted a “circuit breaker” mechanism under which trading sessions may be suspended for 

a period of 30 minutes or one hour whenever the Ibovespa index falls 10% or 15%, respectively, compared to the closing of the 
previous trading session. Also, if after the reopening of the market the Ibovespa falls 20% compared to the closing of the previous day, 
the operations are suspended for a certain period to be defined by the B3. This mechanism is not applied in the last half hour of the 
trading session. 

Settlement of transactions on the B3 is effected three business days after the trade date, without adjustment of the purchase price 
for inflation. Delivery of and payment for shares is made through the facilities of the clearing and settlement chamber of the B3. The 
seller is ordinarily required to deliver shares to the clearing and settlement chamber of the B3 on the second business day following the 
trade date. 

Market Size 

Although the Brazilian equity market is Latin America’s largest in terms of market capitalization, it is smaller, more volatile and 

less liquid than the major U.S. and European securities markets. Moreover, the B3 is significantly less liquid than the NYSE or other 
major exchanges in the world. 

As of December 31, 2017, the aggregate market capitalization of all companies listed on the B3 was equivalent to approximately 

R$3.2 trillion (US$955.6 billion) and the 10 largest companies listed on the B3 represented approximately 53% of the total market 
capitalization of all listed companies. By comparison, as of December 31, 2017, the aggregate market capitalization of the companies 
(including U.S. and non-U.S. companies) listed on the NYSE was approximately US$22.1 trillion. The average daily trading volume of 
the B3 and the NYSE for 2017 was approximately R$8.7 billion (US$2.6 billion) and US$58.2 billion, respectively. 

Although any of the outstanding shares of a listed company may trade on the B3, in most cases fewer than half of the listed shares 

are actually available for trading by the public, the remainder being held by small groups of controlling persons, one principal 
shareholder or governmental entities that rarely trade their shares. For this reason, data showing the total market capitalization of the B3 
tends to overstate the liquidity of the Brazilian equity market. The relative volatility and illiquidity of the Brazilian equity markets may 
substantially limit your ability to sell Oi’s common shares or preferred shares at the time and price you desire and, as a result, could 
negatively impact the market price of these securities. 

Regulation of Foreign Investments 

Trading on the B3 by a holder not deemed to be domiciled in Brazil for Brazilian tax and regulatory purposes, or a non-Brazilian 
holder, is subject to certain limitations under Brazilian foreign investment regulations. With limited exceptions, non-Brazilian holders 
may trade on the B3 only in accordance with the requirements of Annex I of Resolution No. 4,373 of the National Monetary Council. 
Annex I of Resolution No. 4,373 requires that securities held by non-Brazilian holders be registered, maintained in the custody of, or 
maintained in deposit accounts with, financial institutions that are authorized by the Brazilian Central Bank and the CVM, as applicable. 
Subject to limited exceptions provided in the CVM regulation or previous CVM authorization, Annex I of Resolution No. 4,373 
requires non-Brazilian holders (1) to restrict their securities trading to transactions on the B3 or qualified over-the-counter markets; and 
(2) to not transfer the ownership of investments made under Annex I of Resolution No. 4,373 through private transactions. See “Item 
10. Additional Information—Exchange Controls—Resolution No. 4,373” for further information about Resolution No. 4,373, and “Item 
10. Additional Information—Taxation—Brazilian Tax Considerations—Taxation of Gains” for a description of certain tax benefits 
extended to non-Brazilian holders who qualify under Resolution No. 4,373.

B3 Corporate Governance Standards 

In December 2000, the B3 introduced three special listing segments: 

•

•

•

Level 1 of Differentiated Corporate Governance Practices; 

Level 2 of Differentiated Corporate Governance Practices; and 

The Novo Mercado (New Market). 

These special listing segments were designed for the trading of shares issued by companies that voluntarily undertake to abide by 

corporate governance practices and disclosure requirements in addition to those already required by Brazilian law. The inclusion of a 
company in any of the special listing segments requires adherence to a series of corporate governance rules. These rules were designed 
to increase shareholders’ rights and enhance the quality of information provided to shareholders. 

Oi’s shares joined Level 1 of Differentiated Corporate Governance Practices on December 14, 2012. As a Level 1 company, Oi 

must, among other things: 

•

•

•

•

•

•

ensure that shares representing 25% of its total share capital are effectively available for trading; 

adopt offering procedures that favor widespread ownership of shares whenever Oi makes a public offering; 

comply with minimum quarterly disclosure standards, including issuing consolidated financial information, a cash flow 
statement, and special audit revisions on a quarterly basis; 

follow stricter disclosure policies with respect to contracts with related parties, material contracts and transactions involving 
its securities made by its controlling shareholders, if any, directors or executive officers; 

make a schedule of corporate events available to its shareholders; and 

hold public meetings with analysts and investors at least annually. 

Pursuant to the regulations of the B3, the members of Oi’s board of directors and board of executive officers are personally liable 

for its compliance with the rules and regulations of the B3’s Level 1 Listing Segment. 

Moreover, in September 2015, Oi amended its bylaws in order to comply with the rules of the Novo Mercado segment of the B3 

even though Oi has not formally joined this special listing segment. These amendments include the requirement that at least 20% of the 
members of Oi’s board of directors be independent members as defined in the listing regulations of the Novo Mercado and Article 141, 
paragraphs 4 and 5 of the Brazilian Corporate Law. 

ITEM 10. ADDITIONAL INFORMATION 

Description of Oi’s By-laws 

The following is a summary of the material provisions of Oi’s by-laws and of the Brazilian Corporate Law. In Brazil, a company’s 

by-laws (estatuto social) are the principal governing document of a corporation (sociedade anônima). This summary also includes 
relevant provisions of the RJ Plan. In case of a conflict and/or discrepancy between the RJ Plan and Oi’s by-laws’ rules, the RJ Plan 
shall prevail. 

General 

Oi’s registered name is Oi S.A. – In Judicial Reorganization, and its registered office is located in the City of Rio de Janeiro, State 
of Rio de Janeiro, Brazil. Oi’s registration number with the Board of Trade of the State of Rio de Janeiro is No. 33.3.0029520-8. Oi has 
been duly registered with the CVM under No. 11312 since March 27, 1980. Oi’s headquarters are located in City of Rio de Janeiro, 
State of Rio de Janeiro, Brazil. Oi has a perpetual existence. 

As of December 31, 2017 and May 10, 2018, Oi had outstanding share capital of R$21,438,374,154.00, comprised of 825,760,902 
total shares, consisting of 668,033,661 issued common shares and 157,727,241 issued preferred shares, including 148,282,000 common

par value. Under the Brazilian Corporate Law, the aggregate number of Oi’s non-voting and limited voting preferred shares may not 
exceed two-thirds of Oi’s total outstanding share capital. In addition, Oi’s board of directors may increase Oi’s share capital to a 
number of common shares equivalent to R$34,038,701,741.49, provided that no preferred shares are issued by Oi in public or private 
subscriptions.

On March 5, 2018, Oi’s board of directors approved the Capitalization of Credits Capital Increase provided under Sections 4.3.3.2 
and 4.3.3.5 of the RJ Plan, pursuant to which Oi will issue and distribute between 1,039,868,479 and 1,756,054,163 common shares of 
Oi, at a price of R$7.00 per share, resulting in an aggregate capital increase between R$7,279,079,353.00 and R$12,292,379,141.00.

Section 6.1 of the RJ Plan provides that following the completion of the Capitalization of Credits Capital Increase, Oi must 
complete the Cash Capital Increase, pursuant to which Oi must increase its share capital by R$4.0 billion, in order to ensure that it has 
the funds necessary to complete the capital expenditures necessary to modernize its infrastructure and implement the business plan 
provided under Section 6 of the RJ Plan. The Cash Capital Increase is subject to certain conditions precedent, in accordance with the 
Commitment Agreement, and must be completed as soon as possible following the completion of the Capitalization of Credits Capital 
Increase and, in any event, by no later than February 28, 2019. 

Section 5.3 of the RJ Plan also allows Oi to raise up to R$2.5 billion in additional funds during the two-year period beginning on 

the Brazilian Confirmation Date, which occurred on February 5, 2018, including through additional capital increases. Any such 
additional capital increases must comply with the terms of the RJ Plan and Oi’s by-laws. 

Corporate Purposes 

Under Article 2 of Oi’s by-laws, Oi’s corporate purposes are: 

•

•

•

•

•

•

•

•

to offer telecommunications services and all activities required or useful for the operation of these services, in conformity 
with its concessions, authorizations and permits; 

to participate in the capital of other companies; 

to organize wholly-owned subsidiaries for the performance of activities that are consistent with its corporate purposes and 
recommended to be decentralized; 

to import, or promote the importation of, goods and services that are necessary to the performance of activities consistent 
with its corporate purposes;

to perform other activities related to the above corporate purposes. 

Board of Directors 

Oi’s by-laws provide for a board of directors of up to 11 members and an equal number of alternate members. During periods of 
absence or temporary unavailability of a regular member of Oi’s board of directors, the corresponding alternate member substitutes for 
the absent or unavailable regular member. Under Oi’s by-laws, any matters subject to the approval of Oi’s board of directors can be 
approved only by a majority of votes of the members of Oi’s board of directors. In the event of a tie, the chairman of the board of 
directors shall cast the deciding vote. Under Oi’s by-laws, Oi’s board of directors may only deliberate if a majority of its members are 
present at a duly convened meeting. 

Pursuant to Section 9.2 of the RJ Plan, , as from the date of the approval of the RJ Plan on December 20, 2017, Oi has had a 
Transitional Board composed of the members set forth in Exhibit 9.2 of the RJ Plan in order to execute the measures provided for in the 
RJ Plan and taking in consideration the several interests involved in the scope of the judicial reorganization. Members of the 
Transitional Board do not have alternates and may not be removed until the New Board is elected by a general shareholders’ meeting 
that is required to be held within 45 business days following the conclusion of the Capitalization of Credits Capital Increase, as set forth 
in Section 9.3 of the RJ Plan. The Transitional Board shall call this general shareholders’ meeting within five business days following 
the conclusion of the Capitalization of Credits Capital Increase. For more information about the Transitional Board and its members, 
see “Item 6. Directors, Senior Management and Employees—Board of Directors.”

The Transitional Board is presided over by the chairman of the Transitional Board, and, in his absence, on an interim basis, by the 

vice-chairman of the Transitional Board. In accordance with Oi’s by-laws, decisions of the Transitional Board require a quorum of a 
majority of the directors and are taken by a majority vote of those directors present. A director may not cast votes with respect to 
matters in which he has a conflicting interest. In the event of a tie, the chairman of the Transitional Board shall cast the deciding vote. In 
addition to their ordinary course functions provided under Oi’s by-laws, the members of the Transitional Board must oversee the 
execution of the terms of the RJ Plan. 

All prior members or alternates of the Board of Directors who were not designated as members of the Transitional Board of 
Directors pursuant to Section 9.2 of the Plan have been suspended from their duties, including as members of Oi’s advisory committees, 
and therefore cannot participate of any meeting of the Transitional Board of Directors. These members and alternates (a) shall be 
formally replaced by operation of the RJ Plan after the investiture of the New Board in accordance with the RJ Plan and the applicable 
legislation in Brazil, or (b) shall be removed due to the expiration of their terms of office, whichever occurs first. 

Pursuant to Section 9.3 of the RJ Plan, the New Board will be composed of 11 members and no alternate members, all of whom 
must be independent as defined in Oi’s by-laws, provided that one such member shall be Mr. Eleazar de Carvalho Filho (see “Item 6. 
Directors, Senior Management and Employees—Board of Directors—Directors—Eleazar de Carvalho Filho”). The members of the 
New Board will be chosen by the Transitional Board and will serve for a term of two years. The members of the New Board may not be 
removed from office, except due to gross mistake, willful misconduct, gross negligence, abuse of term of office or violation of fiduciary 
duties in accordance with applicable law. Following the expiration of the term of the New Board, the election of subsequent boards of 
directors will follow the rules established by Oi’s by-laws and the Brazilian Corporate Law. 

The following paragraphs describe the material provisions of Oi’s by-laws and of the Brazilian Corporate Law that will apply to 
the members of Oi’s board of directors that are elected following the expiration of the New Board’s two-year term pursuant to the RJ 
Plan. 

Election of Directors 

The members of Oi’s board of directors are elected at general meetings of shareholders for concurrent two-year terms. The tenure 

of the members of the board of directors and board of executive officers will be conditioned on such members signing a Term of 
Consent (Termo de Anuência dos Administradores) in accordance with the Level 1 Corporate Governance Listing Segment of the B3 
and complying with applicable legal requirements. 

Qualification of Directors 

There is no minimum share ownership or residency requirement to qualify for membership on Oi’s board of directors. Oi’s 
by-laws do not require the members of its board of directors to be residents of Brazil. The Brazilian Corporate Law requires each of 
Oi’s executive officers to be residents of Brazil. The tenure of the members of the board of directors will be conditioned on the 
appointment of a representative who resides in Brazil, with powers to receive service of process in proceedings initiated against such 
member based on the corporate legislation, by means of a power-of-attorney with a validity term of at least three years after the end of 
the term of office. Pursuant to Oi’s by-laws, Oi’s directors may not (1) hold positions, particularly positions in advisory, management or 
audit committees, of companies that compete with Oi or its subsidiaries, and (2) may not have conflicts of interest with Oi or its 
subsidiaries. 

Pursuant to Oi’s by-laws, at least 20% of the members of Oi’s board of directors must be independent members as defined in the 

listing regulations of the Novo Mercado segment of the B3 and Article 141, paragraphs 4 and 5 of the Brazilian Corporate Law. 

Fiduciary Duties and Conflicts of Interest 

All members of Oi’s board of directors and their alternates owe fiduciary duties to Oi and all of Oi’s shareholders. 

Under the Brazilian Corporate Law, if one of Oi’s directors or his or her respective alternate or one of Oi’s executive officers has a 

conflict of interest with Oi in connection with any proposed transaction, such director, alternate director or executive officer may not 
vote in any decision of Oi’s board of directors or of Oi’s board of executive officers, as the case may be, regarding such transaction and 
must disclose the nature and extent of his or her conflicting interest for inclusion in the minutes of the applicable meeting. However, if 
one of Oi’s directors is absent from a meeting of Oi’s board of directors, that director’s alternate may vote even if that director has a 
conflict of interest, unless the alternate director shares that conflict of interest or has another conflict of interest.

Any transaction in which one of Oi’s directors (including the alternate members) or executive officers may have an interest, 
including any financings, can only be approved on reasonable and fair terms and conditions that are no more favorable than the terms 
and conditions prevailing in the market or offered by third parties. If any such transaction does not meet this requirement, then the 
Brazilian Corporate Law provides that the transaction may be nullified and the interested director or executive officer must return to Oi 
any benefits or other advantages that he or she obtained from, or as result of, such transaction. Under the Brazilian Corporate Law and 
upon the request of a shareholder who owns at least 5.0% of Oi’s total share capital, Oi’s directors and executive officers must reveal to 
Oi’s shareholders at an ordinary meeting of Oi’s shareholders certain transactions and circumstances that may give rise to a conflict of 
interest. In addition, Oi or any shareholder who owns 5.0% or more of Oi’s share capital may bring an action for civil liability against 
directors and executive officers for any losses caused to Oi as a result of a conflict of interest. 

Compensation 

Under Oi’s by-laws, Oi’s common shareholders approve the aggregate compensation payable to Oi’s board of directors, board of 
executive officers and fiscal council. Subject to this approval, Oi’s board of directors establishes the compensation of its members and 
of Oi’s executive officers. See “Item 6. Directors, Senior Management and Employees—Compensation.” 

Mandatory Retirement 

Neither the Brazilian Corporate Law nor Oi’s by-laws establish any mandatory retirement age for Oi’s directors or executive 

officers. 

Share Capital 

Under the Brazilian Corporate Law, the number of Oi’s issued and outstanding non-voting shares or shares with limited voting 

rights, such as Oi’s preferred shares, may not exceed two-thirds of Oi’s total outstanding share capital. 

Each of Oi’s common shares entitles its holder to one vote at Oi’s annual and extraordinary shareholders’ meetings. Holders of 

Oi’s common shares are not entitled to any preference in respect of dividends or other distributions or otherwise in case of Oi’s 
liquidation. 

Oi’s preferred shares are non-voting, except in limited circumstances, and do not have priority over Oi’s common shares in the 

case of Oi’s liquidation. See “—Voting Rights” for information regarding the voting rights of Oi’s preferred shares and “Item 8. 
Financial Information—Dividends and Dividend Policy—Calculation of Adjusted Net Profit” and “—Dividend Preference of Preferred 
Shares” for information regarding the distribution preferences of Oi’s preferred shares. 

The issuance of new preferred shares by Oi is prohibited. 

Shareholders’ Meetings 

Under the Brazilian Corporate Law, Oi’s shareholders must hold their ordinary annual meeting by April 30 of each year in order 

to: 

•

•

approve or reject the financial statements approved by Oi’s board of directors and board of executive officers, including any 
recommendation by Oi’s board of directors for the allocation of net profit and distribution of dividends; and 

elect members of Oi’s board of directors (upon expiration of their two-year terms) and members of Oi’s fiscal council. 

In addition to the annual shareholders’ meetings, holders of Oi’s common shares have the power to determine any matters related 

to changes in Oi’s corporate purposes and to pass any resolutions they deem necessary to protect and enhance Oi’s development 
whenever Oi’s interests so require, by means of extraordinary shareholders’ meetings. 

Oi convenes shareholders’ meetings, including the annual shareholders’ meeting, by publishing a notice in the national edition of 
Valor Econômico, a Brazilian newspaper, and in the Official Gazette of the State of Rio de Janeiro. Under the Brazilian Corporate Law, 
on the first call of any meeting, the notice must be published no fewer than three times, beginning at least 15 calendar days prior to the 
scheduled meeting date, and companies that have issued ADRs must publish their notice at least 30 days prior to the scheduled meeting 
date. Oi publishes notices of meetings 30 calendar days prior to the scheduled meeting date. The notice must contain the meeting’s 
place, date, time, agenda and, in the case of a proposed amendment to Oi’s by-laws, a description of the subject matter of the proposed 
amendment.

Oi’s board of directors may convene a shareholders’ meeting. Under the Brazilian Corporate Law, shareholders’ meetings also 

may be convened by Oi’s shareholders as follows: 

•

•

•

by any of Oi’s shareholders if, under certain circumstances set forth in the Brazilian Corporate Law, Oi’s directors do not 
convene a shareholders’ meeting required by law within 60 days; 

by shareholders holding at least 5% of Oi’s total share capital if, after a period of eight days, Oi’s directors fail to call a 
shareholders’ meeting that has been requested by such shareholders; and 

by shareholders holding at least 5% of either Oi’s total voting share capital or Oi’s total non-voting share capital, if after a 
period of eight days, Oi’s directors fail to call a shareholders’ meeting for the purpose of appointing a fiscal council that has 
been requested by such shareholders. 

In addition, Oi’s fiscal council may convene a shareholders’ meeting if Oi’s board of directors does not convene an annual 

shareholders’ meeting within 30 days or at any other time to consider any urgent and serious matters. 

Each shareholders’ meeting shall be convened by the chairman of the board of directors. In case of absence or impediment of the 

chairman of the board of directors, the meeting shall be convened by any director chosen at the meeting; and if all other directors are 
absent or impeded, the shareholders present at the meeting shall be responsible for choosing the chairman and the secretary of the 
meeting. 

In order for a valid action to be taken at a shareholders’ meeting, shareholders representing at least 25% of Oi’s issued and 
outstanding voting share capital must be present on first call. However, shareholders representing at least two-thirds of Oi’s issued and 
outstanding voting share capital must be present on first call at a shareholders’ meeting called to amend Oi’s by-laws. If a quorum is not 
present, Oi’s board of directors may issue a second call by publishing a notice as described above at least eight calendar days prior to 
the scheduled meeting. Except as otherwise provided by law, the quorum requirements do not apply to a meeting held on the second 
call, and the shareholders’ meetings may be convened with the presence of shareholders representing any number of shares (subject to 
the voting requirements for certain matters described below). A shareholder without a right to vote may attend a shareholders’ meeting 
and take part in the discussion of matters submitted for consideration. 

Voting Rights 

Under the Brazilian Corporate Law and Oi’s by-laws, each of Oi’s common shares entitles its holder to one vote at Oi’s 

shareholders’ meetings. Oi’s preferred shares generally do not confer voting rights, except in limited circumstances described below. Oi 
may not restrain or deny any voting rights without the consent of the majority of the shares affected. Whenever the shares of any class 
of share capital are entitled to vote, each share is entitled to one vote. 

In accordance with article 72 of Oi’s by-laws, any shareholder or group of shareholders representing a common interest or bound 
by a voting agreement that holds a stake of more than 15% of the number of shares into which the voting capital stock of Oi is divided 
will have their voting rights limited to 15% of the number of Oi’s shares in which the voting capital stock is divided. Currently, such 
limitation is being applied to the votes corresponding to the shares held by Bratel S.à r.l., which exceed the 15% threshold of Oi’s 
voting capital. 

Voting Rights of Common Shares 

Except as otherwise provided by law, resolutions of a shareholders’ meeting are passed by a simple majority vote of the holders of 
Oi’s common shares present or represented at the meeting, without taking abstentions into account. Under the Brazilian Corporate Law, 
the approval of shareholders representing at least half of Oi’s outstanding voting shares is required for the types of action described 
below: 

•

•

•

•

•

reducing the mandatory dividend set forth in Oi’s by-laws; 

changing its corporate purpose; 

merging Oi with another company, or consolidating Oi, subject to the conditions set forth in the Brazilian Corporate Law; 

transferring all of Oi’s shares to another company, known as an “incorporação de ações” under the Brazilian Corporate Law; 

participating in a centralized group of companies (grupo de sociedades) as defined under the Brazilian Corporate Law and 
subject to the conditions set forth in the Brazilian Corporate Law;

•

dissolving or liquidating Oi or canceling any ongoing liquidation; 

creating any founders’ shares (partes beneficiárias) entitling the holders thereof to participate in Oi’s profits; and 

spinning-off of all or any part of Oi. 

Decisions on the transformation of Oi into another form of company require the unanimous approval of Oi’s shareholders, 

including the holders of Oi’s preferred shares. 

Oi is required to give effect to shareholders’ agreements that contain provisions regarding the purchase or sale of Oi’s shares, 
preemptive rights to acquire Oi’s shares, the exercise of the right to vote Oi’s shares or the power to control Oi, if these agreements are 
filed at Oi’s headquarters in Rio de Janeiro. Brazilian Corporate Law requires the president of any meeting of shareholders or board of 
directors to disregard any vote taken by any of the parties to any shareholders’ agreement that has been duly filed with Oi that violates 
the provisions of any such agreement. In the event that a shareholder that is party to a shareholders’ agreement (or a director appointed 
by such shareholder) is absent from any meeting of shareholders or board of directors or abstains from voting, the other party or parties 
to that shareholders’ agreement have the right to vote the shares of the absent or abstaining shareholder (or on behalf of the absent 
director) in compliance with that shareholders’ agreement. Currently, no shareholders’ agreement affecting Oi’s shares has been filed at 
Oi’s headquarters in Rio de Janeiro. 

Under the Brazilian Corporate Law, neither Oi’s by-laws nor actions taken at a shareholders’ meeting may deprive any of Oi’s 

shareholders of certain specific rights, including: 

•

•

•

•

•

the right to participate in the distribution of Oi’s profits; 

the right to participate in any remaining residual assets in the event of Oi’s liquidation; 

the right to supervise the management of Oi’s corporate business as specified in the Brazilian Corporate Law; 

the right to preemptive rights in the event of an issuance of Oi’s shares, debentures convertible into Oi’s shares or 
subscription bonuses, other than as provided in the Brazilian Corporate Law; and 

the right to withdraw from Oi under the circumstances specified in the Brazilian Corporate Law. 

Voting Rights of Minority Shareholders 

Shareholders holding shares representing not less than 5% of Oi’s voting shares have the right to request that Oi adopt a 
cumulative voting procedure for the election of the members of Oi’s board of directors. This procedure must be requested by the 
required number of shareholders at least 48 hours prior to a shareholders’ meeting. 

Under the Brazilian Corporate Law, shareholders that are not controlling shareholders, but that together hold either: 

•

•

preferred shares representing at least 10% of Oi’s total share capital; or 

common shares representing at least 15% of Oi’s voting capital, 

have the right to appoint one member and an alternate to Oi’s board of directors at Oi’s annual shareholders’ meeting. If no group of 
Oi’s common or preferred shareholders meets the thresholds described above, shareholders holding preferred shares or common shares 
representing at least 10% of Oi’s total share capital are entitled to combine their holdings to appoint one member and an alternate to 
Oi’s board of directors. In the event that minority holders of common shares and/or holders of non-voting preferred shares elect a 
director and the cumulative voting procedures described above are also used, Oi’s controlling shareholders, if any, always retain the 
right to elect at least one member more than the number of members elected by the other shareholders, regardless of the total number of 
members of Oi’s board of directors. The shareholders seeking to exercise these minority rights must prove that they have held their 
shares for not less than three months preceding the shareholders’ meeting at which the director will be appointed. 

Under Oi’s by-laws, holders of preferred shares may appoint, by separate voting, one board member and one alternate. 

In accordance with the Brazilian Corporate Law, the holders of Oi’s preferred shares are entitled to elect one member and an 
alternate to Oi’s fiscal council in a separate election. Minority shareholders have the same right as long as they jointly represent 10% or 
more of the voting shares. The other shareholders with the right to vote may elect the remaining members and alternates, who, in any 
event, must number more than the directors and alternates elected by the holders of the preferred shares and the minority shareholders.

Voting Rights of Preferred Shares 

Holders of Oi’s preferred shares are not entitled to vote on any matter, except: 

•

•

•

•

•

with respect to the election of a member of Oi’s board of directors by preferred shareholders holding at least 10% of Oi’s 
total share capital as described above; 

with respect to the election of a member and alternate member of Oi’s fiscal council as described above; 

with respect to the approval of the contracting of foreign entities related to the controlling shareholders of Oi, if any, to 
render management services, including technical assistance, in which decisions preferred shares will have the right to vote 
separately from the common shares; 

with respect to decisions relating to the employment of foreign entities linked to the controlling shareholders of Oi, if any, to 
provide management services, including technical assistance, if the remuneration for such services will exceed 0.2% of Oi’s 
consolidated annual sales for fixed switched telephone service, network service transport telecommunications and the mobile 
highway telephone service, after deductions of tax and contributions; and 

in the limited circumstances described below. 

The Brazilian Corporate Law and Oi’s by-laws provide that Oi’s preferred shares will acquire unrestricted voting rights and will 

be entitled to vote together with Oi’s common shares on all matters put to a vote in Oi’s shareholders’ meetings if the Minimum 
Preferred Dividend is not paid for a period of three years. As a result of Oi’s failure to pay the Minimum Preferred Dividend for 2014, 
2015 and 2016, holders of Oi’s preferred shares obtained full voting rights on April 28, 2017, the date that our annual shareholders’ 
meeting approved our financial statements for fiscal year 2016. 

This voting right will continue until the date on which Oi pays the Minimum Preferred Dividend for the then-most recently 
completed fiscal year. During the period during which holders of Oi’s preferred shares are entitled to vote together with Oi’s common 
shares, holders of Oi’s preferred shares will not be entitled to the separate votes described above with respect to the election of a 
member of Oi’s board of directors, a member and alternate member of Oi’s fiscal council, the approval of the contracting of foreign 
entities, or decisions relating to the employment of foreign entities. 

Limitation on Voting Rights 

Under Oi’s by-laws, any shareholder or group of shareholders, representing the same interest or bound by a voting agreement, that 

hold or may hold in the future, alone or jointly, interest in Oi representing more than 15% of Oi’s voting capital shall have its voting 
rights limited to 15% of the shares with voting rights. 

The limitation above shall be deemed void and without effect in case (1) of capital increase or corporate reorganization that cause 

a dilution superior to 50% of the corporate capital; (2) of public tender offer, in which the offering shareholder or a group of 
shareholders, bound by voting agreement, acquire more than 50% of the shares of the corporate capital; or (3) no shareholder or group 
of shareholders hold, alone or jointly, interests representing more than 15% of Oi’s voting capital. 

Any declaration of vote that overcomes the limits of the by-laws shall not be computed in the shareholders’ meeting. 

Liquidation 

Oi may be liquidated in accordance with the provisions of Brazilian law. In the event of Oi’s extrajudicial liquidation, a 

shareholders’ meeting will determine the manner of Oi’s liquidation and appoint Oi’s liquidator and Oi’s fiscal council that will 
function during the liquidation period. 

Upon Oi’s liquidation, Oi’s preferred shares do not have a liquidation preference over Oi’s common shares in respect of the 
distribution of Oi’s net assets, but shall be entitled to unrestricted voting rights. In the event of Oi’s liquidation, the assets available for 
distribution to Oi’s shareholders would be distributed to Oi’s shareholders in an amount equal to their pro rata share of Oi’s legal 
capital. If the assets to be so distributed are insufficient to fully compensate all of Oi’s shareholders for their legal capital, each of Oi’s 
shareholders would receive a pro rata amount (based on their pro rata share of Oi’s legal capital) of any assets available for 
distribution.

Preemptive Rights 

Under the Brazilian Corporate Law, each of Oi’s shareholders has a general preemptive right to subscribe for Oi’s shares or 
securities convertible into Oi’s shares in any capital increase, in proportion to the number of Oi’s shares held by such shareholder. 

Under Oi’s by-laws, Oi’s board of directors or Oi’s shareholders, as the case may be, may decide not to extend preemptive rights 

to Oi’s shareholders with respect to any issuance of Oi’s shares, debentures convertible into Oi’s shares or warrants made in connection 
with a public exchange made to acquire control of another company or in connection with a public offering or sale through a stock 
exchange. The preemptive rights are transferable and must be exercised within a period of at least 30 days following the publication of 
notice of the issuance of shares or securities convertible into Oi’s shares. Holders of ADSs may not be able to exercise the preemptive 
rights relating to Oi’s shares underlying their ADSs unless a registration statement under the Securities Act is effective with respect to 
those rights or an exemption from the registration requirements of the Securities Act is available. Oi is not obligated to file a registration 
statement with respect to the shares relating to these preemptive rights or to take any other action to make preemptive rights available to 
holders of ADSs, and Oi is not required to file any such registration statement. 

Redemption, Amortization, Tender Offers and Rights of Withdrawal 

Oi’s by-laws or Oi’s shareholders at a shareholders’ meeting may authorize Oi to use its profits or reserves to redeem or amortize 

Oi’s shares in accordance with conditions and procedures established for such redemption or amortization. The Brazilian Corporate 
Law defines “redemption” (resgate de ações) as the payment of the value of the shares in order to permanently remove such shares 
from circulation, with or without a corresponding reduction of Oi’s share capital. The Brazilian Corporate Law defines 
“amortization” (amortização) as the distribution to the shareholders, without a corresponding capital reduction, of amounts that they 
would otherwise receive if Oi were liquidated. If an amortization distribution has been paid prior to Oi’s liquidation, then upon Oi’s 
liquidation, the shareholders who did not receive an amortization distribution will have a preference equal to the amount of the 
amortization distribution in the distribution of Oi’s capital. 

The Brazilian Corporate Law authorizes Oi’s shareholders to approve in a shareholders’ meeting the redemption of Oi’s shares not 

held by Oi’s controlling shareholders, if any, if after a tender offer effected for the purpose of delisting Oi as a publicly held company, 
Oi’s controlling shareholders, if any, increase their participation in Oi’s total share capital to more than 95%. The redemption price in 
such case would be the same price paid for Oi’s shares in any such tender offer. 

The Brazilian Corporate Law and Oi’s by-laws also require the acquirer of control (in case of a change of control) or the controller 
(in case of delisting or a substantial reduction in liquidity of Oi’s shares) to make a tender offer for the acquisition of the shares held by 
minority shareholders under certain circumstances described below under “—Mandatory Tender Offers.” The shareholder can also 
withdraw its capital from Oi under certain circumstances described below under “—Rights of Withdrawal.” 

Mandatory Tender Offers 

The Brazilian Corporate Law requires that if Oi’s common shares are delisted from the B3 or there is a substantial reduction in 
liquidity of Oi’s common shares, as defined by the CVM, in each case as a result of purchases by Oi’s controlling shareholders, Oi’s 
controlling shareholders must effect a tender offer for acquisition of Oi’s remaining common shares at a purchase price equal to the fair 
value of Oi’s common shares taking into account the total number of Oi’s outstanding common shares. 

If Oi’s controlling shareholders enter into a transaction which results in a change of control of Oi, the controlling shareholders 

must include in the documentation of the transaction an obligation to effect a public offer for the purchase of all Oi’s common shares 
for the same price per share paid to the controlling shareholders. The tender offer must be submitted to the CVM within 30 days from 
the date of execution of the documents that provide for the change of control. 

Rights of Withdrawal 

The Brazilian Corporate Law provides that, in certain limited circumstances, a dissenting shareholder may withdraw its equity 

interest from Oi and be reimbursed by Oi for the value of Oi’s common or preferred shares that it then holds. 

This right of withdrawal may be exercised by the dissenting or non-voting holders (including any holder of preferred shares) in the 

event that the holders of a majority of all outstanding common shares authorize: 

•

a reduction of the mandatory dividend set forth in Oi’s by-laws;

to create preferred shares or to increase the existing classes of preferred shares, without maintaining the proportion with the

in the Brazilian Corporate Law; 

changes in the preferences, advantages and conditions of redemption or amortization of one or more classes of preferred 
shares, or the creation of a new class with greater privileges, subject to the conditions set forth in the Brazilian Corporate 
Law; 

Oi’s participation in a centralized group of companies; 

to merge into another company or to consolidate with another company, subject to the conditions set forth in the Brazilian 
Corporate Law; 

a change in Oi’s corporate purpose; 

spinning off of all or any part of Oi, if such spin-off results in (1) a change in Oi’s business purpose (except if the spun-off 
assets revert to a company whose main purpose is the same as Oi’s), (2) a reduction of the mandatory dividend set forth in 
Oi’s by-laws, or (3) Oi’s participation in a centralized group of companies; or 

in one of the following transactions in which the shares held by such holders do not meet liquidity and dispersion thresholds 
under the Brazilian Corporate Law: 

➣ the merger of Oi with another company, or the consolidation of Oi, in a transaction in which Oi is not the surviving 

entity; 

➣ the transfer of all of the outstanding shares of another company to Oi in an incorporação de ações transaction; or 

➣ Oi’s participation in a centralized group of companies. 

Dissenting or non-voting shareholders are also entitled to withdraw in the event that the entity resulting from a merger or spin-off 

does not have its shares listed in an exchange or traded in the secondary market within 120 days from the shareholders’ meeting that 
approved the relevant merger or spin-off. 

Notwithstanding the above, in the event that Oi is consolidated or merged with another company, becomes part of a centralized 

group of companies, or acquires the control of another company for a price in excess of certain limits imposed by the Brazilian 
Corporate Law, holders of any type or class of Oi’s shares or the shares of the resulting entity that have minimal market liquidity and 
are dispersed among a sufficient number of shareholders will not have the right to withdraw. For this purpose, shares that are part of the 
IBOVESPA index are considered liquid, and sufficient dispersion will exist if the controlling shareholder, the parent company or other 
companies under its control hold less than half of the total number of outstanding shares of that type or class. In case of a spin-off, the 
right of withdrawal will only exist if (1) there is a change in the corporate purpose, (2) there is a reduction in the mandatory dividend, or 
(3) the spin-off results in Oi’s participation in a centralized group of companies. 

Only shareholders who own shares on the date of publication of the first notice convening the relevant shareholders’ meeting or 

the material fact notice concerning the relevant transaction is published, whichever is earlier, will be entitled to withdrawal rights. 
Shareholders will only be entitled to exercise withdrawal rights with respect to the shares held by them from such date until the date 
withdrawal rights are exercised. 

The redemption of shares arising out of the exercise of any withdrawal rights would be made at the book value of the shares, 

determined on the basis of Oi’s most recent audited balance sheet approved by Oi’s shareholders. If the shareholders’ meeting 
approving the action that gave rise to withdrawal rights occurred more than 60 days after the date of the most recent approved audited 
balance sheet, a shareholder may demand that its shares be valued on the basis of a balance sheet prepared specifically for this purpose. 

The right of withdrawal lapses 30 days after the date of publication of the minutes of the shareholders’ meeting that approved the 
action that gave rise to withdrawal rights, except when the resolution is approved pending confirmation by the holders of Oi’s preferred 
shares (such confirmation to be given at an extraordinary meeting of such preferred shareholders to be held within one year). In this 
event, the 30-day period for dissenting shareholders begins at the date of publication of the minutes of the extraordinary meeting of such 
preferred shareholders. Oi’s shareholders may reconsider any resolution giving rise to withdrawal rights within 10 days after the 
expiration of the exercise period of withdrawal rights if Oi’s management believes that the withdrawal of shares of dissenting 
shareholders would jeopardize Oi’s financial stability.

Liability of Oi’s Shareholders for Further Capital Calls 

Neither Brazilian law nor Oi’s by-laws require any capital calls. Oi’s shareholders’ liability for capital calls is limited to the 

payment of the issue price of any shares subscribed or acquired. 

Inspection of Corporate Records 

Shareholders that own 5% or more of Oi’s outstanding share capital have the right to inspect Oi’s corporate records, including 

shareholders’ lists, corporate minutes, financial records and other documents of Oi, if (1) Oi or any of its officers or directors have 
committed any act contrary to Brazilian law or Oi’s by-laws, or (2) there are grounds to suspect that there are material irregularities in 
Oi. However, in either case, the shareholder that desires to inspect Oi’s corporate records must obtain a court order authorizing the 
inspection. 

Disclosures of Share Ownership 

Brazilian regulations require that (1) each of Oi’s direct or indirect controlling shareholders, if any, and (2) any person or group of 

persons representing a person that has directly or indirectly acquired or sold an interest that would result in an increase or decrease 
corresponding to 5%, or any 5% multiple thereof, of the total number of Oi’s shares of any type or class to disclose its or their share 
ownership or divestment to Oi, and Oi is responsible for transmitting such information to the CVM and the market. In addition, if a 
share acquisition results in, or is made with the intention of, change of control or company’s management structure, as well as 
acquisitions that cause the obligation of performing a tender offer, the persons acquiring such number of shares are required to publish a 
statement containing certain required information about such acquisition. 

Oi’s controlling shareholders, if any, members of Oi’s board of directors, board of executive officers, fiscal council and members 

of other bodies created pursuant to Oi’s by-laws with technical or consulting functions must file a statement of any change in their 
holdings of Oi’s shares with the CVM and the Brazilian stock exchanges on which Oi’s securities are traded. Oi also must disclose any 
trading of its shares by Oi or Oi’s controlled or related companies. 

Form and Transfer 

Oi’s preferred shares and common shares are in book-entry form, registered in the name of each shareholder or its nominee. The 
transfer of Oi’s shares is governed by Article 35 of the Brazilian Corporate Law, which provides that a transfer of shares is effected by 
Oi’s transfer agent, Banco do Brasil S.A., by an entry made by the transfer agent in its books, upon presentation of valid written share 
transfer instructions to Oi by a transferor or its representative. When preferred shares or common shares are acquired or sold on a 
Brazilian stock exchange, the transfer is effected on the records of Oi’s transfer agent by a representative of a brokerage firm or the 
stock exchange’s clearing system. The transfer agent also performs all the services of safe-keeping of Oi’s shares. Provided that the 
provisions of Resolution No. 4,373 are observed, transfers of Oi’s shares by a non-Brazilian investor are made in the same manner and 
are executed on the investor’s behalf by the investor’s local agent. If the original investment was registered with the Brazilian Central 
Bank pursuant to foreign investment regulations, the non-Brazilian investor is also required to amend, if necessary, through its local 
agent, the electronic certificate of registration to reflect the new ownership. 

The B3 operates a central clearing system, the CSD. A holder of Oi’s shares may choose, at its discretion, to participate in this 

system, and all shares that such shareholder elects to be put into the clearing system are deposited in custody with the CSD (through a 
Brazilian institution that is duly authorized to operate by the Brazilian Central Bank and maintains a clearing account with the CSD). 
Shares subject to the custody of the CSD are noted as such in Oi’s registry of shareholders. Each participating shareholder will, in turn, 
be registered in the register of the CSD and will be treated in the same manner as shareholders registered in Oi’s books. 

Material Contracts 

We have not entered into any material contracts, other than those described in this annual report or entered into in the ordinary 

course of business.

Exchange Controls 

There are no restrictions on ownership or voting of Oi’s capital stock by individuals or legal entities domiciled outside Brazil. 
However, the right to convert dividend payments, payments of interest on shareholders’ equity and proceeds from the sale of Oi’s share 
capital into foreign currency and to remit such amounts outside Brazil is subject to exchange control restrictions under foreign 
investment legislation and foreign exchange regulations, which generally require, among other things, the registration of the relevant 
investment with the Brazilian Central Bank and/or the CVM, as the case may be. 

Investments in Oi’s common shares or preferred shares by (1) a holder not deemed to be domiciled in Brazil for Brazilian tax 

purposes (including a non-Brazilian holder) who is registered with the CVM under Annex I of Resolution No. 4,373, or (2) the 
depositary, are eligible for registration with the Brazilian Central Bank. This registration (the amount so registered is referred to as 
registered capital) allows the remittance outside Brazil of foreign currency, converted at the market rate, acquired with the proceeds of 
distributions on, and amounts realized through, dispositions of Oi’s common shares or preferred shares. 

The registered capital per newly issued common share or preferred share purchased in the form of an ADS, or purchased in Brazil 

under Annex I of Resolution No. 4,373 and deposited with the depositary in exchange for an ADS, will be equal to its purchase price 
and to the market value of the corresponding shares on the date of the deposit, respectively. 

The registered capital under Annex I of Resolution No. 4,373 per common share or preferred share withdrawn upon cancellation 

of a corresponding ADS will be the U.S. dollar equivalent of the market value of the common or preferred share, as the case may be, on 
the B3 on the day of withdrawal. Such cancellation is also subject to the execution of simultaneous foreign exchange agreements 
without the actual inflow and outflow of funds to and from Brazil, or the Symbolic FX Agreements. The U.S. dollar equivalent will be 
determined upon the execution of the Symbolic FX Agreement. 

Foreign Direct Investment and Portfolio Investment 

Investors (individuals, legal entities, mutual funds and other collective investment entities) domiciled, residing or headquartered 

outside Brazil may register their investments in Oi’s shares as foreign portfolio investments under Annex I of Resolution No. 4,373 
(described below) or as foreign direct investments under Law No. 4,131 (described below). Registration under Annex I of Resolution 
No. 4,373 or Law No. 4,131 generally enables the conversion of dividends, other distributions and sales proceeds received in 
connection with registered investments into foreign currency and the remittance of such amounts outside Brazil. Registration under 
Annex I of Resolution No. 4,373 affords favorable tax treatment to non-Brazilian portfolio investors who are not resident in a favorable 
tax jurisdiction, which is defined by Brazilian tax legislation as any country or location that: (1) does not tax income, or taxes income at 
a rate lower than 20% (or 17% in the case of countries or regimes abiding by the international policy for tax transparency); or (2) does 
not disclose or imposes restrictions on the disclosure of certain information concerning the shareholding composition of a legal entity, 
its ownership or the effective beneficiary of income attributable to the foreigners. See “—Taxation—Brazilian Tax Considerations.” 

Annex I of Resolution No. 4,373 

All investments made by a non-Brazilian investor under Annex I of Resolution No. 4,373 are subject to an electronic registration 
with the Brazilian Central Bank. This registration permits the conversion of dividend payments, payments of interest on shareholders’ 
equity and proceeds from the sale of Oi’s share capital into foreign currency and the remission of such amounts outside Brazil. 

Under Annex I of Resolution No. 4,373, non-Brazilian investors registered with the CVM may invest in almost all financial assets 

and engage in almost all transactions available to Brazilian investors in the Brazilian financial and capital markets without obtaining a 
separate Brazilian Central Bank registration for each transaction, provided that certain requirements are fulfilled. Under Annex I of 
Resolution No. 4,373, the definition of a non-Brazilian investor includes individuals, legal entities, mutual funds and other collective 
investment entities domiciled or headquartered outside Brazil. 

Pursuant to Annex I of Resolution No. 4,373, non-Brazilian investors must: 

•

•

•

•

appoint at least one representative in Brazil with powers to take action relating to its investments, which must be a financial 
institution duly authorized by the Brazilian Central Bank; 

appoint an authorized custodian in Brazil for its investments, which must be an institution duly authorized by the CVM; 

complete the appropriate foreign investor registration forms; 

appoint a tax representative in Brazil;

through its representative, register as a non-Brazilian investor with the CVM; 

through its representative, register its investments with the Brazilian Central Bank; and 

obtain a taxpayer identification number from the Brazilian federal tax authorities. 

The securities and other financial assets held by a non-Brazilian investor pursuant to Annex I of Resolution No. 4,373 must be 
registered or maintained in deposit accounts or under the custody of an entity duly licensed by the Brazilian Central Bank or the CVM, 
as applicable, or be registered in registration, clearing and custody systems authorized by the Brazilian Central Bank or by the CVM, as 
applicable. Subject to limited exceptions provided in the CVM regulation or previous CVM authorization, the trading of securities held 
under Annex I of Resolution No. 4,373 is restricted to transactions carried out on stock exchanges or through organized 
over-the-counter markets licensed by the CVM. 

The offshore transfer or assignment of the securities or other financial assets held by non-Brazilian investors pursuant to Annex I 

of Resolution No. 4,373 are prohibited, except for transfers (1) resulting from consolidation, spin-off, merger or merger of shares or 
occurring upon the death of an investor by operation of law or will; (2) resulting from a corporate reorganization effected abroad, as 
long as the final beneficiaries and the amount of the assets remain the same, or (3) authorized by the CVM. 

Annex II of Resolution No. 4,373 – ADSs 

Annex II of Resolution No. 4,373 of the National Monetary Council provides for the issuance of depositary receipts in foreign 
markets in respect of shares of Brazilian issuers. The Common and Preferred ADS program was approved by the Brazilian Central 
Bank and the CVM prior to the issuance of the Common and Preferred ADSs. Accordingly, as a general rule, the proceeds from the sale 
of ADSs by non-Brazilian resident ADS holders outside Brazil are not subject to Brazilian foreign investment controls, and holders of 
the ADSs who are not resident in a “tax haven” jurisdiction are entitled to favorable tax treatment. See “—Item 10. Additional 
Information—Taxation—Brazilian Tax Considerations—Taxation of Gains.” 

Oi pays dividends and other cash distributions with respect to Oi’s common shares and preferred shares in reais. Oi has obtained 
electronic certificates of foreign capital registration from the Brazilian Central Bank in the name of the Preferred ADS Depositary and 
the Common ADS Depositary to be maintained by the custodian on behalf of the Preferred ADS Depositary and the Common ADS 
Depositary. Pursuant to this registration, the custodian is able to convert dividends and other distributions with respect to Oi’s common 
shares and preferred shares represented by ADSs into foreign currency and remit the proceeds outside Brazil to the Preferred ADS 
Depositary and the Common ADS Depositary so that the Preferred ADS Depositary and the Common ADS Depositary may distribute 
these proceeds to the holders of record of the ADSs. 

In the event that a holder of Common or Preferred ADSs exchanges those Common or Preferred ADSs for the underlying common 

shares or preferred shares, respectively, the holder must: 

•

•

convert its investment in those shares into a foreign portfolio investment under Annex I of Resolution No. 4,373, subject to 
the execution of Symbolic FX Agreements; or 

convert its investment in those shares into a direct foreign investment under Law No. 4,131, subject to the execution of 
Symbolic FX Agreements. 

The custodian is authorized to update the electronic registration of the Common and Preferred ADS Depositary to reflect 

conversions of Common and Preferred ADSs into foreign portfolio investments under Resolution No. 4,373. 

If a holder of Common or Preferred ADSs elects to convert its Common and Preferred ADSs, as the case may be, into a foreign 
portfolio investment under Annex I of Resolution No. 4,373 or into a foreign direct investment under Law No. 4,131, the conversion 
will be effected before the Brazilian Central Bank by the custodian after receipt of an electronic request from the depositary with details 
of the transaction. If a foreign direct investor under Law No. 4,131 elects to deposit its common shares or preferred shares into the 
relevant ADS program in exchange for ADSs, such holder will be required to present to the custodian evidence of payment of capital 
gains taxes and of the execution of Symbolic FX Agreements. See “—Item 10. Additional Information—Taxation—Brazilian Tax 
Considerations—Taxation of Gains” for details of the tax consequences to an investor residing outside Brazil of investing in Oi’s 
common shares or preferred shares in Brazil.

If a holder of ADSs wishes to convert its investment in Oi’s shares into either a foreign portfolio investment under Annex I of 

Resolution No. 4,373 or a foreign direct investment under Law No. 4,131, it should begin the process of obtaining its own foreign 
investor registration with the Brazilian Central Bank or with the CVM, as the case may be, in advance of exchanging the Common or 
Preferred ADSs for the underlying common or preferred shares, respectively. A non-Brazilian holder of common or preferred shares 
may experience delays in obtaining a foreign investor registration, which may delay remittances outside Brazil, which may in turn 
adversely affect the amount, in U.S. dollars, received by the non-Brazilian holder. 

Unless the holder has registered its investment with the Brazilian Central Bank, the holder may not be able to convert the proceeds 
from the disposition of, or distributions with respect to, such preferred shares or the common shares into foreign currency or remit those 
proceeds outside Brazil. In addition, if the non-Brazilian investor resides in a “tax haven” jurisdiction or is not an investor registered 
under Annex I of Resolution No. 4,373, the investor will be subject to less favorable tax treatment than a holder of ADSs. See 
“—Taxation—Brazilian Tax Considerations.” 

Law 4,131 

To obtain a certificate of foreign capital registration from the Brazilian Central Bank under Law No. 4,131, a foreign direct 

investor must: 

•

•

•

•

register as a foreign direct investor with the Brazilian Central Bank; 

obtain a taxpayer identification number from the Brazilian tax authorities; 

appoint a tax representative in Brazil; and 

appoint a representative in Brazil for service of process in respect of suits based on the Brazilian Corporate Law.

Foreign direct investors under Law No. 4,131 may sell their shares in either private or open market transactions, but these 
investors will generally be subject to less favorable tax treatment on gains with respect to Oi’s common or preferred shares. See 
“—Taxation—Brazilian Tax Considerations.” 

Taxation 

The following discussion contains a description of the material Brazilian and U.S. federal income tax consequences of the 
acquisition, ownership and disposition of Oi’s common shares, preferred shares or ADSs. The following discussion does not purport to 
be a comprehensive description of all the tax considerations that may be relevant to a decision to purchase, hold or dispose of Oi’s 
common shares, preferred shares or ADSs. This discussion is based upon the tax laws of Brazil and the United States and regulations 
under these tax laws as currently in effect, which are subject to change. 

Although there is at present no income tax treaty between Brazil and the United States, the tax authorities of the two countries 
have had discussions that may culminate in such a treaty. No assurance can be given, however, as to whether or when a treaty will enter 
into force or how it will affect the U.S. holders of Oi’s common shares, preferred shares or ADSs. 

Prospective purchasers of Oi’s common shares, preferred shares or ADSs should consult their own tax advisors as to the tax 

consequences of the acquisition, ownership and disposition of Oi’s common shares, preferred shares or ADSs in their particular 
circumstances. 

Brazilian Tax Considerations 

The following discussion contains a description of the material Brazilian tax consequences, subject to the limitations set forth 
herein, of the acquisition, ownership and disposition of Oi’s common shares, preferred shares or ADSs by a non-Brazilian holder. This 
discussion is based on the tax laws of Brazil and regulations thereunder in effect on the date hereof, which are subject to change 
(possibly with retroactive effect). This discussion does not specifically address all of the Brazilian tax considerations that may be 
applicable to any particular non-Brazilian holder. Therefore, each non-Brazilian holder should consult its own tax advisor about the 
Brazilian tax consequences of an investment in Oi’s common shares, preferred shares or ADSs. 

Individuals domiciled in Brazil and Brazilian companies are taxed in Brazil on the basis of their worldwide income which includes 

earnings of Brazilian companies’ foreign subsidiaries, branches and affiliates. The earnings of branches of foreign companies and 
non-Brazilian residents, or nonresidents, in general are taxed in Brazil only on income derived from Brazilian sources. 

Dividends 

Dividends paid by a Brazilian corporation, such as Oi, including stock dividends and other dividends paid to a non-Brazilian 
holder of Oi’s common shares, preferred shares or ADSs, are currently not subject to income tax withholding in Brazil to the extent that 
such amounts are related to profits generated after January 1, 1996. Dividends paid from profits generated before January 1, 1996 may 
be subject to Brazilian income tax withholding at varying rates, according to the tax legislation applicable to each corresponding year. 
See “—New Tax Regime Created by Law No. 12,973” for further information regarding dividends based on the 2014 calendar-year 
profits.

Interest on Shareholders’ Equity 

Law No. 9,249, dated December 26, 1995, as amended, allows a Brazilian corporation, such as Oi, to make distributions to 
shareholders of interest on shareholders’ equity, and treat those payments as a deductible expense for purposes of calculating Brazilian 
corporate income tax, and, since 1998, social contribution on net profit as well, as long as the limits described below are observed. 
These distributions may be paid in cash. For tax purposes, the deductible amount of this interest is limited to the daily pro rata variation 
of the TJLP, as determined by the Brazilian Central Bank from time to time, and the amount of the deduction may not exceed the 
greater of: 

•

•

50% of net income (after the deduction of social contribution on net profit but before taking into account the provision for 
corporate income tax and the amounts attributable to shareholders as interest on shareholders’ equity) for the period in 
respect of which the payment is made; and 

50% of the sum of retained profits and income reserves as of the date of the beginning of the period in respect of which the 
payment is made.

Payment of interest on shareholders’ equity to a non-Brazilian holder is subject to income tax withholding at the rate of 15%, or 

25% if the non-Brazilian holder is domiciled in a country or location that is considered to be a “tax haven jurisdiction” for this purpose. 
For this purpose, the definition of “tax haven” encompasses countries and locations (1) that do not impose income tax, (2) that impose 
income tax at a rate of 20% or less, or (3) where local laws do not allow access to information related to shareholding composition, 
ownership of investments, or the identity of the beneficial owners of earnings that are attributed to non-residents. 

On November 28, 2014, the Brazilian Revenue Service issued Rule No. 488, which reduces the threshold income tax rate for 
determining a “tax favorable jurisdiction” from 20% to 17%. Please refer to “—Discussion on Definition of ‘Tax Haven’ Jurisdictions” 
below for a discussion that the definition of “tax haven” jurisdiction may be broadened by an interpretation of Law No. 11,727. These 
payments of interest on shareholders’ equity may be included, at their net value, as part of any mandatory dividend. To the extent 
payment of interest on net equity is so included, Oi is required to distribute to shareholders an additional amount to ensure that the net 
amount received by them, after payment of the applicable income tax withholding, is at least equal to the mandatory dividend. 

Payments of interest on shareholders’ equity are decided by Oi’s shareholders, at its annual shareholders meeting, on the basis of 

recommendations of its board of directors. No assurance can be given that Oi’s board of directors will not recommend that future 
distributions of profits should be made by means of interest on shareholders’ equity instead of by means of dividends. 

Taxation of Gains 

Under Law No. 10,833, enacted on December 29, 2003, the gain on the disposition or sale of assets located in Brazil by a 

non-Brazilian holder, whether to another non-Brazilian resident or to a Brazilian resident, may be subject to income capital gain taxes in 
Brazil. 

With respect to the disposition of Oi’s common shares or preferred shares, as they are assets located in Brazil, the non-Brazilian 
holder should be subject to income tax on the gains assessed, following the rules described below, regardless of whether the transactions 
are conducted in Brazil or with a Brazilian resident. 

With respect to Oi’s ADSs, although the matter is not entirely clear, arguably the gains realized by a non-Brazilian holder upon the 

disposition of ADSs to another non-Brazilian resident will not be taxed in Brazil, on the basis that ADSs are not “assets located in 
Brazil” for the purposes of Law No. 10,833. We cannot assure you, however, that the Brazilian tax authorities or the Brazilian courts 
will agree with this interpretation. As a result, gains on a disposition of ADSs by a non-Brazilian holder to a Brazilian resident, or even 
to a non-Brazilian resident, in the event that courts determine that ADSs would constitute assets located in Brazil, may be subject to 
income tax in Brazil according to the rules applicable to Oi’s common shares and preferred shares, described above. 

As a general rule, gains realized as a result of a disposition of Oi’s common shares, preferred shares or ADSs are the positive 

difference between the amount realized on the transaction and the acquisition cost of Oi’s common shares, preferred shares or ADSs. 

Under Brazilian law, however, income tax rules on such gains can vary depending on the domicile of the non-Brazilian holder, the 
type of registration of the investment by the non-Brazilian holder with the Brazilian Central Bank and how the disposition is carried out, 
as described below. 

Gains realized on a disposition of shares carried out on a Brazilian stock exchange (which includes the organized over-the-counter 

market) are: 

•

•

exempt from income tax when realized by a non-Brazilian holder that (1) has registered its investment in Brazil with the 
Brazilian Central Bank under the rules of Resolution No. 4,373, dated September 14, 2014, which replaced Resolution 2,689 
dated January 26, 2000 (“4,373 Holder”), and (2) is not a resident in a country or location which is defined as a “tax haven” 
jurisdiction for this purposes (as described below); or 

subject to income tax at a rate of up to 25% in any other case, including a case of gains assessed by a non-Brazilian holder 
that is not a 4,373 Holder, and is a resident of a country or location defined as a “tax haven” jurisdiction for this purpose (as 
described below). In these cases, a withholding income tax of 0.005% of the sale value will be applicable and can be later 
offset with the eventual income tax due on the capital gain. This 0.005% withholding income tax is not levied on day trade 
transactions.

Any other gains assessed on a disposition of Oi’s common shares or preferred shares that is not carried out on a Brazilian stock 

exchange are subject to income tax at the rate of 15%, or 25% in the case of a non-Brazilian holder which resides in a “tax haven” 
jurisdiction according to the definition applicable to this situation. In the case that these gains are related to transactions conducted on 
the Brazilian non-organized over-the-counter market with intermediation, income tax withholding of 0.005% will also be applicable and 
can be offset against the eventual income tax due on the capital gain. This 0.005% income tax withholding is not levied in day trade 
transactions. 

In the case of 4,373 Holders, a country or location should only be defined as a “tax haven” jurisdiction when it (1) does not tax 

income, or (2) taxes income at a rate of 20% or less. In the case of gains realized by non-Brazilian holders other than 4,373 Holders, a 
country or location should be defined as a “tax haven” jurisdiction when it (a) does not tax income, (b) taxes income at a rate of 20% or 
less, or (c) where local laws do not allow access to information related to shareholding composition, ownership of investments, or the 
identity of the beneficial owners of earnings that are attributed to non-residents. See “—Discussion on Definition of ‘Tax Haven’ 
Jurisdictions” for more information on this maximum rate of 20% and its reduction to 17%. 

In the case of redemption of securities or capital reduction by a Brazilian corporation, such as Oi, the positive difference between 

the amount effectively received by the non-Brazilian holder and the corresponding acquisition cost is treated, for tax purposes, as 
capital gain derived from sale or exchange of shares not carried out on a Brazilian stock exchange market, and is therefore subject to 
income tax at the rate of 15% or 25%, as the case may be. 

The deposit of Oi’s common or preferred shares in exchange for ADSs will be subject to Brazilian income tax if the acquisition 

cost of the shares is lower than (1) the average price per share on a Brazilian stock exchange on which the greatest number of such 
shares were sold on the day of deposit, or (2) if no shares were sold on that day, the average price on the Brazilian stock exchange on 
which the greatest number of shares were sold in the 15 trading sessions immediately preceding such deposit. In such case, the 
difference between the acquisition cost and the average price of the shares calculated as above will be considered to be a capital gain 
subject to income tax withholding at the rate of 15% or 25%, as the case may be. In some circumstances, there may be arguments to 
claim that this taxation is not applicable in the case of a non-Brazilian holder that is a 4,373 Holder and is not a resident in a “tax haven” 
jurisdiction for this purpose. The availability of these arguments to any specific holder of Oi’s common shares or preferred shares will 
depend on the circumstances of such holder. Prospective holders of Oi’s common shares or preferred shares should consult their own 
tax advisors as to the tax consequences of the deposit of Oi’s common shares or preferred shares in exchange for ADSs. 

Any exercise of preemptive rights relating to Oi’s common shares, preferred shares or ADSs will not be subject to Brazilian 
taxation. Any gain on the sale or assignment of preemptive rights relating to Oi’s common shares or preferred shares, including the sale 
or assignment carried out by the depositary, on behalf of non-Brazilian holders of ADSs, will be subject to Brazilian income taxation 
according to the same rules applicable to the sale or disposition of Oi’s common shares or preferred shares. 

On March 16, 2016, Provisional Measure No. 692 was converted into Law 13,259/16 and increased tax rates on capital gains 

earned by Brazilian individuals and certain legal entities. The new rates should apply as from 2017 as follows: (1) 15% on the capital 
gain not exceeding R$5,000,000; (2) 17.5% on the capital gain amount between R$5,000,000 and R$10,000,000; (3) 20% on the capital 
gain amount between R$10,000,000 and R$30,000,000; and (4) 22.5% on the capital gain which exceeds R$30,000,000. The new rates 
should also apply to non-Brazilian holders depending on their type of investment, jurisdiction and the sale transaction, subject to 
confirmation on a case by case basis. 

Discussion on Definition of “Tax Haven” Jurisdictions 

Until December 2008, under Brazilian tax laws, a Low Tax Jurisdiction (“LTJ”) was defined as a country or location that does not 

impose taxation on income, or imposes the income tax at a rate lower than 20%. There was also the concept of Tax Favorable 
Jurisdiction (“TFJ”) which also included the jurisdictions where local laws do not allow access to information related to shareholding 
composition, ownership of investments, or the identity of the beneficial owners of earnings that are attributed to non-resident. There 
was a list of TFJs enacted by Brazilian tax authorities by means of Normative Instruction No. 188/2002. 

On June 24, 2008, Law No. 11,727 introduced the concept of Privileged Tax Regimes (“PTRs”), which encompasses the countries 

and jurisdictions that: (1) do not tax income or tax it at a maximum rate lower than 20%; (2) grant tax advantages to a non-resident 
entity or individual (a) without the need to carry out a substantial economic activity in the country or a said territory or (b) conditioned 
on the non-exercise of a substantial economic activity in the country or a said territory; (3) do not tax or taxes proceeds generated 
abroad at a maximum rate lower than 20.0%; or (4) restrict the ownership disclosure of assets and ownership rights or restricts 
disclosure about economic transactions carried out.

As a consequence, in 2010, a new list was enacted by Brazilian tax authorities, via Normative Instruction 1,037/10 (“NI 
1,037/10”), which includes the countries considered as TFJs and the locations considered as granting PTRs. Under Section 2 of NI 
1,037/10, companies incorporated as LLCs in the US, and companies benefiting from some holding regimes in Europe, may be 
considered as granting PTRs. We highlight that there would be solid legal grounds to sustain that the list should be interpreted as an 
exhaustive list, so that only the countries and locations listed should be viewed as TFJs and PTRs, according to their specific 
qualification. The interpretation of the current Brazilian tax legislation should lead to the conclusion that the concept of PTR should 
only apply for certain Brazilian tax purposes, such as transfer pricing and thin capitalization. According to this interpretation, the 
concept of PTR should not be applied in connection with the taxation of dividends, interest on shareholders’ equity and gains related to 
investments made by non-Brazilian holders in Brazilian corporations. Regulations and non-binding tax rulings issued by Brazilian 
federal tax authorities seem to confirm this interpretation. 

Notwithstanding the above, we recommend that you consult your own tax advisors regarding the consequences of the 

implementation of Law No. 11,727, NI 1,037/10 and of any related Brazilian tax law or regulation concerning LTJs, TFJs, or PTRs. 

On November 28, 2014, the Brazilian Revenue Service issued Rule No. 488, which reduces the threshold income tax rate for 

determining a TFJ from 20% to 17%. This rule also applies for purposes of the definition of PTRs. In any event, differing 
interpretations by the tax authorities in the application of this rule may result in a lower number of jurisdictions being characterized as 
TFJ. Furthermore, the RFB issued Normative Instruction No. 1,530/14 providing that compliance with such standards requires: 
(1) signature or negotiations completion for a treaty or agreement allowing the exchange of information related to identification of 
income beneficiaries, shareholding structure, ownership of goods or rights, or economic transactions that are carried out; and 
(2) commitment to the criteria set out in international anti-tax evasion forums of which Brazil is a member. A new list of TFJs and 
PTRs has not been issued to date. 

Tax on Foreign Exchange Transactions (IOF/Exchange Tax) 

Brazilian law imposes a Tax on Foreign Exchange Transactions, or IOF/Exchange, on the conversion of reais into foreign 
currency and on the conversion of foreign currency into reais. The currently applicable rate for most types of foreign exchange 
transactions is 0.38%. However, other rates apply to specific types of transactions. 

Any inflow of funds related to investments carried out on the Brazilian financial and capital markets by 4,373 Holders is currently 
subject to the IOF/Exchange Tax at a rate of zero percent. Foreign exchange transactions related to outflows of funds in connection with 
investments carried out on the Brazilian financial and capital markets are subject to the IOF/Exchange Tax at a rate of zero percent. 

The IOF/Exchange also levies at a zero percent rate in case of dividends and interest on shareholders’ equity paid by a Brazilian 

corporation to non-Brazilian holders. 

The Brazilian government is permitted to increase the rate of the IOF/Exchange at any time by up to 25% on the foreign exchange 

transaction amount. However, any increase in rates will only apply to transactions carried out after such increase in rates enters into 
force. 

The purchase of ADSs by a non-Brazilian holder outside Brazil generally does not require the execution of a foreign exchange 

agreement with the Brazilian Central Bank. If this is the case, the IOF/Exchange Tax is not due. The IOF/Exchange Tax is levied at a 
zero percent rate in connection with foreign exchange agreements, without any actual flows of funds, that are required for a cancellation 
of ADSs and exchange for shares traded on a Brazilian stock exchange. 

Tax on Transactions Involving Securities (IOF/ Securities Tax) 

Brazilian law imposes a Tax on Transactions Involving Bonds and Securities, or IOF/Bonds and Securities, due on transactions 

involving bonds and securities, including those carried out on a Brazilian stock exchange. 

The rate of IOF/Bonds and Securities applicable to most transactions involving shares and ADSs is currently zero, although the 

Brazilian government may increase such rate at any time up to 1.5% of the transaction amount per day, but only in respect of future 
transactions. 

The transfer (cessão) of shares traded on a Brazilian stock exchange for the issuance of depositary receipts to be traded outside 

Brazil, such as ADSs, is currently subject to the IOF/Bonds and Securities at a zero percent rate.

New Tax Regime Created by Law No. 12,973 

Normative Instruction No. 1,397/2013, or NI 1,397/2013, published in the Official Gazette on September 17, 2013, was enacted to 

regulate the transitional tax regime, or RTT, in force between January 1, 2008 and December 31, 2014, to adjust, for tax purposes, the 
net profit calculated under the IFRS rules in accordance with Law 11,638/2007. According to NI 1,397/2013, for purposes of 
calculating dividends and interest on net equity, taxpayers must use the accounting books prepared according to the criteria in force on 
December 31, 2007, and not IFRS. According to such provisions, depending on the tax basis used by the taxpayer, certain dividend 
distributions may be subject to a 15% withholding tax (or 25% if the taxpayer resides in a “tax haven” jurisdiction). 

Provisional Measure 627/2013 was converted into Law No. 12,973, enacted on May 13, 2014 (“Law 12,973/14”), which revoked 
the RTT and introduced a new tax regime, in line with the current Brazilian accounting standards (IFRS). According to Law 12,973/14, 
companies electing to be taxed under the new regime on January 1, 2014 as opposed to January 1, 2015 will not be subject to taxation 
under NI 1,397/2013 on their dividend distributions based on 2014 profits. Companies that did not elect to be taxed under the new 
regime on January 1, 2014, might be subject to withholding income tax on a part of the dividend distributions based on 2014 profits, 
according to the rules set forth under NI 1,397/2013. 

Other Brazilian Taxes 

There are no Brazilian inheritance, gift or succession taxes applicable to the ownership, transfer or disposition of Oi’s common 

shares, preferred shares or ADSs by a non-Brazilian holder except for gift and inheritance taxes levied by some states in Brazil. There 
are no Brazilian stamp, issue, registration, or similar taxes or duties payable by non-Brazilian holders of Oi’s common shares, preferred 
shares or ADSs. 

U.S. Federal Income Tax Considerations 

The following is a discussion of the material U.S. federal income tax consequences that may be relevant with respect to the 

acquisition, ownership and disposition of Oi’s common shares, preferred shares or ADSs, which are evidenced by ADRs. This 
description addresses only the U.S. federal income tax considerations of U.S. Holders (as defined below) that are initial purchasers of 
Oi’s common shares, preferred shares or ADSs and that will hold such shares or ADSs as capital assets. This description does not 
address tax considerations applicable to holders that may be subject to special tax rules, such as banks, financial institutions, insurance 
companies, real estate investment trusts, grantor trusts, regulated investment companies, dealers or traders in securities or currencies, 
tax-exempt entities, pension funds, persons that received Oi’s common shares, preferred shares or ADSs pursuant to an exercise of 
employee stock options or rights or otherwise as compensation for the performance of services, persons that will hold Oi’s common 
shares, preferred shares or ADSs as a position in a “straddle” or as a part of a “hedging,” “conversion” or other risk reduction 
transaction for U.S. federal income tax purposes, persons that have a “functional currency” other than the U.S. dollar, persons that will 
own the common shares, preferred shares or ADSs of Oi through partnerships or other pass through entities, holders subject to the 
alternative minimum tax, certain former citizens or long-term residents of the United States or holders that own (or are deemed to own) 
10% or more (by combined voting power or combined value) of Oi’s shares. 

This description does not address any state, local or non-U.S. tax consequences of the acquisition, ownership and disposition of 
Oi’s common shares, preferred shares or ADSs by U.S. Holders. Moreover, this description does not address the consequences of any 
U.S. federal tax other than income tax, including but not limited to the U.S. federal estate and gift taxes. This description is based on 
(1) the Internal Revenue Code of 1986, as amended (the “Code”), existing and temporary U.S. Treasury Regulations and judicial and 
administrative interpretations thereof, in each case as in effect and available on the date of this annual report, as well as proposed 
Treasury Regulations available on the date of this annual report, and (2) in part, the representations of the depositary and the assumption 
that each obligation in the deposit agreement and any related agreement will be performed in accordance with its terms. All of the 
foregoing is subject to change, which change could apply retroactively and could affect the tax consequences described below. Holders 
should consult their tax advisers to determine the particular tax consequences to such holders of the acquisition, ownership and 
disposition of Oi’s common shares, preferred shares or ADSs, including the applicability and effect of U.S. state, local and non-U.S. tax 
laws.

As used herein, the term “U.S. Holder” means, for U.S. federal tax purposes, a beneficial owner of Oi’s common shares, preferred 

shares or ADSs that is: 

•

•

•

•

an individual citizen or resident of the United States; 

a corporation organized under the laws of the United States, any state thereof or the District of Columbia; 

an estate the income of which is subject to U.S. federal income taxation regardless of its source; or 

a trust if (1) a court within the United States is able to exercise primary supervision over its administration, and (2) one or 
more United States persons have the authority to control all of the substantial decisions of such trust. 

If a partnership (or any other entity treated as a partnership for U.S. federal income tax purposes) holds Oi’s common shares, 

preferred shares or ADSs, the tax treatment of a partner in such partnership will generally depend on the status of the partner and the 
activities of the partnership. A partnership or its partners should consult their tax advisor as to its tax consequences. 

Treatment of ADSs 

In general, for U.S. federal income tax purposes, a holder of an ADR evidencing an ADS will be treated as the beneficial owner of 
Oi’s common shares or preferred shares represented by the applicable ADS. The U.S. Treasury Department has expressed concern that 
depositaries for ADSs, or other intermediaries between the holders of shares of an issuer and the issuer, may be taking actions that are 
inconsistent with the claiming of U.S. foreign tax credits by U.S. Holders of such receipts or shares. Such actions include, for example, 
a pre-release of an ADS by a depositary. Accordingly, the analysis regarding the availability of a U.S. foreign tax credit for Brazilian 
taxes, the sourcing rules described below and the availability of the reduced tax rate for dividends received by certain non-corporate 
holders, each could be affected by future actions that may be taken by the U.S. Treasury Department. 

Passive Foreign Investment Company Rules 

A Non-U.S. corporation will be classified as a PFIC for U.S. federal income tax purposes in any taxable year in which, after 
applying certain look-through rules, either (1) at least 75 percent of its gross income is “passive income,” or (2) at least 50 percent of 
the average value of its gross assets is attributable to assets that produce “passive income” or is held for the production of passive 
income. Passive income for this purpose generally includes dividends, interest, royalties, rents and gains from commodities and 
securities transactions. For purposes of the PFIC asset test, the aggregate fair market value of the assets of a publicly traded foreign 
corporation generally is treated as being equal to the sum of the aggregate value of the outstanding stock and the total amount of the 
liabilities of such corporation (the “Market Capitalization”). 

Based on certain estimates of the gross income and gross assets of Oi, the nature of its business, the size of its investment in 

certain subsidiaries, and its anticipated Market Capitalization, Oi believes that for Oi’s taxable years ended December 31, 2016, and 
December 31, 2017, it was not a PFIC for U.S. federal income tax purposes. Nevertheless, because PFIC status is determined annually 
based on our income, assets and activities for the entire taxable year, it is not possible to determine whether we will be characterized as 
a PFIC for the taxable year ending December 31, 2018, or for any subsequent year, until after the close of the year. Furthermore, 
because Oi determines the value of our gross assets based on the Market Capitalization test, a decline in the value of our ordinary shares 
and preferred shares may result in our becoming a PFIC. Accordingly, there can be no assurance that we will not be considered a PFIC 
for any taxable year. Moreover, Oi has not obtained an opinion from counsel regarding the PFIC status of Oi for any taxable period. 

If Oi is a PFIC for any taxable year during which a U.S. Holder holds Oi’s common shares, preferred shares or ADSs, Oi generally 

will continue to be treated as a PFIC with respect to such U.S. Holder for all succeeding years during which such U.S. Holder holds 
common shares, preferred shares or ADSs of Oi, unless Oi ceases to be a PFIC and such U.S. Holder makes a “deemed sale” election 
with respect to such common shares, preferred shares or ADSs of Oi. If such election is made, such U.S. Holder will be deemed to have 
sold such common shares, preferred shares or ADSs of Oi held by such U.S. Holder at their fair market value on the last day of the last 
taxable year in which Oi qualified as a PFIC, and any gain from such deemed sale would be subject to the consequences described in 
the following paragraph. After the deemed sale election, such U.S. Holder’s common shares, preferred shares or ADSs of Oi with 
respect to which the deemed sale election was made will not be treated as shares in a PFIC, and such U.S. Holder would not be subject 
to the rules described below with respect to any “excess distribution” such U.S. Holder receives from Oi or any gain from an actual sale 
or other disposition of such common shares, preferred shares or ADSs of Oi, unless Oi subsequently becomes a PFIC. The rules 
dealing with deemed sale elections are complex. U.S. Holders are encouraged to consult their tax advisor as to the possibility 
and consequences of making a deemed sale election if Oi ceases to be treated as a PFIC and such election becomes available to 
U.S. Holders.

For each taxable year that Oi is treated as a PFIC with respect to a U.S. Holder, any excess distribution (generally a distribution in 
excess of 125% of the average distribution over a three-year period or shorter holding period for Oi’s common shares, preferred shares 
or ADSs) and realized gain will be treated as ordinary income and will be subject to tax as if (1) the excess distribution or gain had been 
realized ratably over the U.S. Holder’s holding period, (2) the amount deemed realized in each year had been subject to tax in each such 
year at the highest marginal rate for such year (other than income allocated to the current period or any taxable period before Oi became 
a PFIC, which would be subject to tax at the U.S. Holder’s regular ordinary income rate for the current year and would not be subject to 
the interest charge discussed below), and (3) the interest charge generally applicable to underpayments of tax had been imposed on the 
taxes deemed to have been payable in those years. U.S. Holders should consult their own tax advisors regarding the tax consequences of 
Oi being treated as a PFIC with respect to such U.S. Holders. The tax liability for amounts allocated to taxable years prior to the year of 
disposition or excess distribution cannot be offset by any net operating losses for such years, and gains (but not losses) realized on the 
sale or other disposition of common shares, preferred shares or ADSs of Oi cannot be treated as capital, even if a U.S. Holder holds the 
common shares, preferred shares or ADSs of Oi as capital assets. In addition, a U.S. Holder’s tax basis in common shares, preferred 
shares or ADSs of Oi that are acquired from a decedent would not receive a step-up to fair market value as of the date of the decedent’s 
death but instead would be equal to the decedent’s basis, if lower. 

If Oi is treated as a PFIC with respect to a U.S. Holder for any taxable year, to the extent any of Oi’s subsidiaries are also PFICs or 

Oi makes direct or indirect equity investments in other entities that are PFICs, such U.S. Holder may be deemed to own shares in such 
lower-tier PFICs that are directly or indirectly owned by Oi in that proportion which the value of the common shares, preferred shares 
or ADSs of Oi such U.S. Holder owns bears to the value of all of Oi’s common shares, preferred shares and ADSs, and such U.S. 
Holder may be subject to the adverse tax consequences described in the preceding two paragraphs with respect to the shares of such 
lower-tier PFICs that such U.S. Holder would be deemed to own. U.S. Holders should consult their tax advisor regarding the 
application of the PFIC rules to any of Oi’s subsidiaries. 

If Oi is treated as a PFIC with respect to a U.S. Holder of the common shares, preferred shares or ADSs of Oi, such U.S. Holder 
may be able to make certain elections that may alleviate certain of the tax consequences referred to above. Where a company that is a 
PFIC meets certain reporting requirements, a U.S. Holder can avoid certain adverse PFIC consequences described above by making a 
“qualified electing fund,” or QEF, election to be taxed currently on its proportionate share of the PFIC’s ordinary income and net capital 
gains. However, Oi does not intend to comply with the necessary accounting and record keeping requirements that would allow a U.S. 
Holder to make a QEF election with respect to Oi. 

If Oi’s common shares, preferred shares or ADSs are “regularly traded” on a “qualified exchange,” a U.S. Holder may make a 
mark-to-market election with respect to the common shares, preferred shares or ADSs of Oi, as the case may be. If a U.S. Holder makes 
the mark-to-market election, for each year in which Oi is a PFIC, the holder will generally include as ordinary income the excess, if 
any, of the fair market value of Oi’s common shares, preferred shares, or ADSs, as the case may be, at the end of the taxable year over 
their adjusted tax basis, and will be permitted an ordinary loss in respect of the excess, if any, of the adjusted tax basis of Oi’s common 
shares, preferred shares or ADSs, over their fair market value at the end of the taxable year (but only to the extent of the net amount of 
previously included income as a result of the mark-to-market election). If a U.S. Holder makes the election, the holder’s tax basis in 
Oi’s common shares, preferred shares or ADSs, as the case may be, will be adjusted to reflect the amount of any such income or loss. 
Any gain recognized on the sale or other disposition of Oi’s common shares, preferred shares or ADSs will be treated as ordinary 
income. Oi’s common shares, preferred shares and ADSs will be considered “marketable stock” if they are traded on a qualified 
exchange, other than in de minimis quantities, on at least 15 days during each calendar quarter. The NYSE is a qualified exchange and 
the B3 may constitute a qualified exchange for this purpose provided the B3 meets certain trading volume, listing, financial disclosure, 
surveillance and other requirements set forth in applicable U.S. Treasury Regulations. However, Oi cannot be certain that its common 
shares, preferred shares or ADSs will continue to trade on the B3 or the NYSE, respectively, or that its common shares, preferred shares 
or ADSs will be traded on at least 15 days in each calendar quarter in other than de minimis quantities. U.S. Holders should be aware, 
however, that for each taxable year that Oi is treated as a PFIC with respect to a U.S. Holder, the interest charge regime described above 
could be applied to indirect distributions or gains deemed to be attributable to such U.S. Holder in respect of any of Oi’s subsidiaries 
that also may be determined to be a PFIC, and the mark-to-market election generally would not be effective for such subsidiaries. Each 
U.S. Holder should consult its own tax advisor to determine whether a mark-to-market election is available and the consequences of 
making an election if Oi were characterized as a PFIC. 

If a U.S. Holder owns common shares, preferred shares or ADSs of Oi during any year in which Oi was a PFIC, such U.S. Holder 

generally must file IRS Form 8621 with respect to Oi, generally with the U.S. Holder’s federal income tax return for that year.

Taxation of Dividends 

Subject to the discussion above under “—Passive Foreign Investment Company Rules,” in general, the gross amount of a 
distribution made with respect to a common share, preferred share or ADS of Oi (which for this purpose shall include distributions of 
interest attributable to shareholders’ equity before any reduction for any Brazilian taxes withheld therefrom) will, to the extent made 
from the current or accumulated earnings and profits of Oi, as determined under U.S. federal income tax principles, constitute a 
dividend to a U.S. Holder for U.S. federal income tax purposes. Non-corporate U.S. Holders may be taxed on dividends from a 
qualified foreign corporation at the lower rates applicable to long-term capital gains (i.e., gains with respect to capital assets held for 
more than one year). A foreign corporation is treated as a qualified foreign corporation with respect to dividends received from that 
corporation on shares or ADSs that are readily tradable on an established securities market in the United States. U.S. Treasury 
Department guidance indicates that the ADSs of Oi (which are listed on the NYSE), but not the common or preferred shares of Oi, are 
readily tradable on an established securities market in the United States. Thus, subject to the discussion above under “—Passive Foreign 
Investment Company Rules,” dividends that Oi pays on the ADS, but not on the common shares or preferred shares of Oi, currently 
meet the trading conditions discussed above required for these reduced tax rates. However, there can be no assurance that the ADSs will 
be considered readily tradable on an established securities market in later years. Furthermore, a U.S. Holder’s eligibility for such 
preferential rate is subject to certain holding period requirements and the non-existence of certain risk reduction transactions with 
respect to the ADSs and such preferential rate is not available if Oi is a PFIC for the taxable year in which such dividend is paid or was 
a PFIC for the taxable year preceding the taxable year in which such dividend is paid. Such dividends will not be eligible for the 
dividends received deduction generally allowed to corporate U.S. Holders. Subject to the discussion above under “—Passive Foreign 
Investment Company Rules,” if a distribution exceeds the amount of the current and accumulated earnings and profits of Oi, it will be 
treated as a non-taxable return of capital to the extent of the U.S. Holder’s tax basis in the common share, preferred share or ADS of Oi 
on which it is paid and thereafter as capital gain. Oi does not maintain calculations of the earnings and profits of Oi under U.S. federal 
income tax principles. Therefore, U.S. Holders should expect that distributions by Oi generally will be treated as dividends for U.S. 
federal income tax purposes. 

A dividend paid in reais will be includible in the income of a U.S. Holder at its value in U.S. dollars calculated by reference to the 

prevailing spot market exchange rate in effect on the day it is received by the U.S. Holder in the case of Oi’s common shares or 
preferred shares or, in the case of a dividend received in respect of ADSs of Oi, on the date the dividend is received by the depositary, 
whether or not the dividend is converted into U.S. dollars. Assuming the payment is not converted at that time, the U.S. Holder will 
have a tax basis in reais equal to that U.S. dollar amount, which will be used to measure gain or loss from subsequent changes in 
exchange rates. Any gain or loss realized by a U.S. Holder that subsequently sells or otherwise disposes of reais, which gain or loss is 
attributable to currency fluctuations after the date of receipt of the dividend, will be ordinary gain or loss. The amount of any 
distribution of property other than cash will be the fair market value of such property on the date of distribution. 

The gross amount of any dividend paid (which will include any amounts withheld in respect of Brazilian taxes) with respect to a 
common share, preferred share or ADS of Oi will be subject to U.S. federal income taxation as foreign source dividend income, which 
may be relevant in calculating a U.S. Holder’s foreign tax credit limitation. Subject to limitations under U.S. federal income tax law 
concerning credits or deductions for foreign taxes and certain exceptions for short-term and hedged positions, any Brazilian withholding 
tax will be treated as a foreign income tax eligible for credit against a U.S. Holder’s U.S. federal income tax liability (or at a U.S. 
Holder’s election, may be deducted in computing taxable income if the U.S. Holder has elected to deduct all foreign income taxes for 
the taxable year). The limitation on foreign taxes eligible for the U.S. foreign tax credit is calculated separately with respect to specific 
“baskets” of income. For this purpose, the dividends should generally constitute “passive category income,” or in the case of certain 
U.S. Holders, “general category income.” The rules with respect to foreign tax credits are complex, and U.S. Holders are urged to 
consult their own tax advisors regarding the availability of the foreign tax credit under their particular circumstances.

Treatment of Preferred Stock 

Section 305 of the Code provides special rules for the tax treatment of preferred stock. According to the U.S. Treasury Regulations 

under that section, the term preferred stock generally refers to stock which enjoys certain limited rights and privileges (generally 
associated with specified dividend and liquidation priorities) but does not participate in corporate growth to any significant extent. 
While Oi’s preferred shares have some preferences over its common shares, the preferred shares are not fixed as to dividend payments 
or liquidation value. Consequently, although the matter is not entirely clear, because the determination is highly factual in nature, it is 
more likely than not that the preferred shares of Oi will be treated as “common stock” within the meaning of section 305 of the Code. If 
the preferred shares are treated as “common stock” for purposes of section 305 of the Code, distributions to U.S. Holders of additional 
shares of such “common stock” or preemptive rights relating to such “common stock” with respect to their preferred shares or ADSs 
that are made as part of a pro rata distribution to all shareholders in most instances will not be subject to U.S. federal income tax. On the 
other hand, if the preferred shares are treated as “preferred stock” within the meaning of section 305 of the Code, and if a U.S. Holder 
receives a distribution of additional shares or preemptive rights as described in the preceding sentence, such distributions (including 
amounts withheld in respect of any Brazilian taxes), as discussed more fully below, will be treated as dividends to the same extent and 
in the same manner as distributions payable in cash. In that event, the amount of such distribution (and the basis of the new shares or 
preemptive rights so received) will equal the fair market value of the shares or preemptive rights on the date of distribution. 

Sale, Exchange or Other Disposition of the Common Shares, Preferred Shares or ADSs of Oi 

A deposit or withdrawal of common shares or preferred shares by a U.S. Holder in exchange for the ADS that represent such 
shares will not result in the realization of gain or loss for U.S. federal income tax purposes. Subject to the discussion above under 
“—Passive Foreign Investment Company Rules,” a U.S. Holder generally will recognize capital gain or loss upon a sale, exchange or 
other disposition of a common share, preferred share or ADS of Oi held by the U.S. Holder or the depositary, as the case may be, in an 
amount equal to the difference between the U.S. Holder’s adjusted basis in its common shares, preferred shares or ADSs of Oi 
(determined in U.S. dollars) and the U.S. dollar amount realized on the sale, exchange or other disposition. If a Brazilian tax is withheld 
on the sale, exchange or other disposition of a share, the amount realized by a U.S. Holder will include the gross amount of the proceeds 
of that sale, exchange or other disposition before deduction of the Brazilian tax. In the case of a non-corporate U.S. Holder, the 
maximum marginal U.S. federal income tax rate applicable to capital gain generally will be lower than the maximum marginal U.S. 
federal income tax rate applicable to ordinary income (other than, as discussed above, certain dividends) if such holder’s holding period 
for such common share, preferred share or ADS of Oi exceeds one year (i.e., such gain is a long-term capital gain). Capital gain, if any, 
realized by a U.S. Holder on the sale or exchange of a common share, preferred share or ADS of Oi generally will be treated as U.S. 
source income for U.S. foreign tax credit purposes. Consequently, in the case of a disposition or deposit of a common share, preferred 
share or ADS of Oi that is subject to Brazilian tax, the U.S. Holder may not be able to use the foreign tax credit for that Brazilian tax 
unless it can apply the credit against U.S. tax payable on other income from foreign sources in the appropriate income category, or, 
alternatively, it may take a deduction for the Brazilian tax if it elects to deduct all of its foreign income taxes. The deductibility of 
capital losses is subject to limitations under the Code. 

The initial tax basis of a U.S. Holder’s common shares, preferred shares or ADSs of Oi will be the U.S. dollar value of the reais-
denominated purchase price determined on the date of purchase. If the common shares, preferred shares or ADSs of Oi are treated as 
traded on an “established securities market,” a cash basis U.S. Holder, or, if it elects, an accrual basis U.S. Holder, will determine the 
dollar value of the cost of such common shares, preferred shares or ADSs by translating the amount paid at the spot rate of exchange on 
the settlement date of the purchase. The conversion of U.S. dollars to reais and the immediate use of that currency to purchase common 
shares, preferred shares or ADSs generally will not result in taxable gain or loss for a U.S. Holder. 

With respect to the sale or exchange of Oi’s common shares, preferred shares or ADSs, the amount realized generally will be the 
U.S. dollar value of the payment received determined on the date of disposition. If Oi’s common shares, preferred shares or ADSs are 
treated as traded on an “established securities market,” a cash basis taxpayer, or, if it elects, an accrual basis taxpayer, will determine 
the U.S. dollar value of the amount realized by translating the amount received at the spot rate of exchange on the settlement date of the 
sale. 

Other Brazilian Taxes 

Any Brazilian IOF/Exchange Tax or IOF/Bonds and Securities Tax (as discussed under “—Brazilian Tax Considerations” above) 

may not be treated as a creditable foreign tax for U.S. federal income tax purposes, although a U.S. Holder may be entitled to deduct 
such taxes if it elects to deduct all of its foreign income taxes. U.S. Holders should consult their tax advisors regarding the U.S. federal 
income tax consequences of these taxes.

Certain U.S. Holders who are individuals, estates or trusts may be required to pay an additional 3.8% tax on, among other things, 

dividends and capital gains from the sale or other disposition of Oi’s common shares, preferred shares, or ADSs. 

Information Reporting and Backup Withholding 

In general, information reporting will apply to dividends in respect of Oi’s common shares, preferred shares, or ADSs and the 
proceeds from the sale, exchange or redemption of Oi’s common shares, preferred shares, or ADSs that are paid to a U.S. Holder within 
the United States (and in certain cases, outside the United States) by a U.S. payor or U.S. middleman, unless such U.S. Holder is an 
exempt recipient such as a corporation. A backup withholding tax may apply to such payments if a U.S. Holder fails to provide a 
taxpayer identification number or certification of other exempt status or fail to report in full dividend and interest income. 

Any amounts withheld under the backup withholding rules will be allowed as a refund or a credit against a U.S. Holder’s U.S. 

federal income tax liability provided the required information is furnished to the Internal Revenue Service in a timely manner. 

Certain U.S. Holders who are individuals are required to report information relating to an interest in Oi’s common shares, 
preferred shares, or ADSs, subject to certain exceptions (including an exception for Oi’s common shares, preferred shares, or ADSs 
held in accounts maintained by U.S. financial institutions). U.S. Holders are urged to consult their tax advisors regarding their 
information reporting obligations, if any, with respect to their acquisition, ownership and disposition of Oi’s common shares, preferred 
shares, or ADSs.

ITEM 11. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK 

We are exposed to market risks related to changes in exchange rates and interest rates. The principal market for the products and 

services of our continuing operations is Brazil, and substantially all of the revenues of our continuing operations are denominated in 
reais. 

We have historically conducted derivative transactions to manage certain market risks, mainly the interest rate risk and foreign 
exchange risk. However, In connection with our deteriorating financial condition and the commencement of the RJ Proceedings, we 
reversed our derivative financial instruments during the second and third quarters of 2016. As at December 31, 2017 and 2016, we are 
not a party to any derivative financial instruments.

Exchange Rate Risk 

We are exposed to foreign exchange risk because a significant portion of our equipment costs, such as costs relating to switching 

centers and software used for upgrading network capacity, are primarily denominated in foreign currencies or linked to foreign 
currencies, primarily the U.S. dollar. During 2017 and 2016, approximately 10.9% and 14.8%, respectively, of our capital expenditures 
were U.S. dollar-denominated or linked to the U.S. dollar. A hypothetical, instantaneous 10.0% depreciation of the real against the U.S. 
dollar as of (1) December 31, 2017 would have resulted in an increase of R$56.3 million in the cost of our capital expenditures during 
2017, and (2) December 31, 2016 would have resulted in an increase of R$308.6 million in the cost of our capital expenditures during 
2016, assuming that we would have incurred all of these capital expenditures notwithstanding the adverse change in the exchange rates. 

Our financing cost and the amount of financial liabilities that we record are also exposed to exchange rate risk. As of 

December 31, 2017, R$36,577 million, or 74.4%, of our total consolidated loans and financing was denominated in foreign currency, 
and as of December 31, 2016, R$36,693 million, or 74.5%, of our total consolidated loans and financing was denominated in foreign 
currency. As a result of the commencement of the RJ Proceedings on June 20, 2016, our foreign currency-denominated financial 
liabilities are part of the list of payables subject to renegotiation, payment of interest and repayment of principal of our loans and 
financing were suspended from the date of the commencement of the RJ proceeding through December 31, 2017, and we have not 
recorded exchange rate gains and losses on the balances of these financial liabilities during 2017 or 2016. 

Had our payment obligations under these financial liabilities not been suspended, we would have recorded foreign currency and 

monetary restatement losses of R$2,932 million during 2017 and R$2,461 million during 2016 with respect to our foreign currency-
denominated financial liabilities, based on exchange rates in effect at the end of 2017 and 2016. The potential additional losses on 
foreign currency and monetary restatement during 2017 that would result from a hypothetical, instantaneous 10.0% depreciation of the 
real against the U.S. dollar and the euro as of December 31, 2017 would be approximately R$3,986 million, assuming that the amount 
and composition of our debt instruments were unchanged. The potential increase in our total consolidated debt obligations that would 
result from a hypothetical, instantaneous 10.0% depreciation of the real against the U.S. dollar and the euro as of December 31, 2017 
would be approximately R$3,995 million. 

The potential additional losses on foreign currency and monetary restatement during 2016 that would result from a hypothetical, 

instantaneous 10.0% depreciation of the real against the U.S. dollar and the euro as of December 31, 2016 would be approximately 
R$3,490 million, assuming that the amount and composition of our debt instruments were unchanged. The potential increase in our total 
consolidated debt obligations that would result from a hypothetical, instantaneous 10.0% depreciation of the real against the U.S. dollar 
and the euro as of December 31, 2016 would be approximately R$3,499 million. 

Interest Rate Risk 

We are exposed to interest rate risk because a significant portion of our indebtedness bears interest at floating rates. As of 

December 31, 2017, our total outstanding loans and financing was R$49,130 million, of which R$15,870 million, or 32.3%, bore 
interest at floating rates, including R$10,889 million of real-denominated indebtedness that bore interest at rates based on the CDI rate, 
TJLP rate or IPCA rate, and R$4,982 million of foreign currency-denominated indebtedness that bore interest at rates based on U.S. 
dollar LIBOR. 

As of December 31, 2016, our total outstanding indebtedness was R$49,265 million, of which R$15,870 million, or 32.2%, bore 

interest at floating rates, including R$10,889 million of real-denominated indebtedness that bore interest at rates based on the CDI rate, 
TJLP rate or IPCA rate, and R$4,982 million of foreign currency-denominated indebtedness that bore interest at rates based on U.S. 
dollar LIBOR. 

We invest our excess liquidity (R$6,999 million as of December 31, 2017 and R$7,849 million as of December 31, 2016) mainly 

in (1) certificates of deposit and time deposits issued by global and domestic financial institutions with AAA and AA ratings from 
international rating agencies, (2) in short-term instruments denominated in reais that generally pay interest at overnight interest rates 
based on the CDI rate which partially mitigates our exposure to Brazilian interest rate risk, and (3) in investment funds created by top 
Brazilian asset managers exclusively for us. The fund managers of the investment funds created for us are responsible for managing our 
funds, subject to the direction of our senior management and board of directors. Currently, these funds are comprised mainly of 
government bonds and other low-risk financial instruments linked to the CDI rate. 

As a result of the commencement of the RJ Proceedings on June 20, 2016, our financial liabilities are part of the list of payables 

subject to renegotiation, payment of interest and repayment of principal of our loans and financing were suspended from the date of the 
commencement of the RJ proceeding through December 31, 2017, and we have not recorded interest expenses on the balances of these 
financial liabilities during 2017 or 2016.

Had our payment obligations under these financial liabilities not been suspended, we would have recorded interest expenses of 

R$3,334 million during 2017 and R$3,410 million during 2016 with respect to our financial liabilities, based on the applicable interest 
rates in effect at the end of 2017 and 2016. The potential additional interest expense during 2017 that would have resulted from a 
hypothetical, instantaneous and unfavorable change of 100 basis points in the interest rates on January 1, 2017 would be approximately 
R$141 million considering the impact in our debt obligations, but excluding the additional interest income that we would receive on our 
financial investments. The potential additional interest expense during 2016 that would have resulted from a hypothetical, instantaneous 
and unfavorable change of 100 basis points in the interest rates on January 1, 2016 would be approximately R$128 million considering 
the impact in our debt obligations, but excluding the additional interest income that we would receive on our financial investments. 

This sensitivity analysis is based on the assumption of an unfavorable 100 basis points movement of the interest rates applicable to 

each homogeneous category of financial liabilities and sustained over a period of one year. A homogeneous category is defined 
according to the currency in which financial assets and liabilities are denominated and assumes the same interest rate movement within 
each homogeneous category (e.g., reais). As a result, our interest rate risk sensitivity model may overstate the impact of interest rate 
fluctuation for such financial instruments, as consistently unfavorable movements of all interest rates are unlikely. 

ITEM 12. DESCRIPTION OF SECURITIES OTHER THAN EQUITY SECURITIES 

The depositary collects its fees for the delivery and surrender of ADSs directly from investors depositing shares or surrendering 

ADSs or from intermediaries acting for them. The depositary also collects fees for making distributions to investors by deducting those 
fees from the amounts distributed or by selling a portion of distributable property to pay the fees. The depositary may collect its annual 
fee for depositary services by deductions from cash distributions or by directly billing investors or by charging the book-entry system 
accounts of participants acting for them. The depositary may generally refuse to provide fee-attracting services until its fees for those 
services are paid. 

Persons depositing or withdrawing shares must pay: 

•

•

•

•

•

•

•

•

•

US$5.00 (or less) per 100 ADSs (or portion of 100 ADSs) for the issuance of ADSs, including issuances resulting from a 
distribution of shares or rights or other property; 

US$5.00 (or less) per 100 ADSs (or portion of 100 ADSs) for the cancellation of ADSs for the purpose of withdrawal, 
including in the event of the termination of the deposit agreement; 

US$0.02 (or less) per ADS (or portion thereof) for any cash distribution; 

US$0.02 (or less) per ADS (or portion thereof) per calendar year for depositary services; 

in the event of distributions of securities (other than Oi’s Class A preferred shares), a fee equivalent to the fee for the 
execution and delivery of ADRs referred to above, which would have been charged, as a result of the deposit of such 
securities (treating such securities as Class A Preferred Shares for the purposes of this fee); 

registration or transfer fees for the transfer and registration of shares on Oi’s share register to or from the name of 
the depositary or its agent when you deposit or withdraw shares; 

expenses of the depositary for (1) cable, telex and facsimile transmissions (when expressly provided in the 
deposit agreement), and (2) converting foreign currency to U.S. dollars; 

taxes and other governmental charges the depositary or the custodian have to pay on any ADS or share underlying an ADS, 
for example, stock transfer taxes, stamp duty or withholding taxes, as necessary; and 

any charges incurred by the depositary or its agents for servicing the deposited securities, as necessary. 

Subject to certain terms and conditions, the depositary has agreed to reimburse Oi for certain expenses it incurs that are related to 

establishment and maintenance expenses of the ADS program, including the standard out-of-pocket maintenance costs for the ADRs, 
which consist of the expenses of postage and envelopes for mailing annual and interim financial reports, printing and distributing 
dividend checks, electronic filing of U.S. Federal tax information, mailing required tax forms, stationery, postage, facsimile, and 
telephone calls. There are limits on the amount of expenses for which the depositary will reimburse us, but the amount of 
reimbursement available to Oi is not necessarily tied to the amount of fees the depositary collects from investors. 

During the year ended December 31, 2017, we received US$427,905 in reimbursements from the depositary of Oi’s ADSs. During 

the year ended December 31, 2016, we did not receive reimbursements from the depositary of Oi’s ADSs.

ITEM 14. MATERIAL MODIFICATIONS TO THE RIGHTS OF SECURITY HOLDERS AND USE OF PROCEEDS 

Not applicable. 

ITEM 15. CONTROLS AND PROCEDURES 

Disclosure Controls and Procedures 

Our chief executive officer, or CEO, and chief financial officer, or CFO, are responsible for establishing and maintaining our 
disclosure controls and procedures. These controls and procedures were designed to ensure that information that we are required to 
disclose in the reports that we file under the Exchange Act is recorded, processed, summarized and reported within the time periods 
specified in the applicable rules and forms of the SEC, and that it is accumulated and communicated to our management, including our 
CEO and CFO, as appropriate to allow timely decisions regarding required disclosure. 

We performed an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures as of 

December 31, 2017 under the supervision of our CEO and CFO. There are inherent limitations to the effectiveness of any system of 
disclosure controls and procedures, including the possibility of human error and the circumvention or overriding of the controls and 
procedures. Accordingly, even effective controls and procedures can only provide reasonable assurance of achieving their control 
objectives. 

Based on our evaluation, our CEO and CFO concluded that our disclosure controls and procedures were not effective as of 

December 31, 2017, and that the design and operation of our disclosure controls and procedures were not effective to provide 
reasonable assurance that all material information relating to our company was reported as required because material weaknesses in the 
current operation of our internal control over financial reporting were identified as described below.

Management’s Annual Report on Internal Control over Financial Reporting and Report of Independent Registered Public 
Accounting Firm

Our management is responsible for establishing and maintaining adequate internal controls over financial reporting. 

Our internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of 

financial reporting and the preparation of consolidated financial statements for external purposes in accordance with applicable 
generally accepted accounting principles. Our internal control over financial reporting includes those policies and procedures that (1) 
pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of our 
assets, (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of consolidated financial 
statements in accordance with applicable generally accepted accounting principles, and that our receipts and expenditures are being 
made only in accordance with authorizations of our management and directors, and (3) provide reasonable assurance regarding 
prevention or timely detection of unauthorized acquisition, use, or disposition of our assets that could have a material effect on the 
consolidated financial statements. 

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, 
projections of any evaluation of the effectiveness of internal control to future periods are subject to the risk that controls may become 
inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. 

Under the supervision and with the participation of our CEO and CFO, our management conducted an assessment of the effectiveness 
of our internal control over financial reporting as of December 31, 2017 based on the criteria established in “Internal Control 
—Integrated Framework (2013)” issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on this 
assessment, our management concluded that as of December 31, 2017, our internal control over financial reporting was not effective 
because material weaknesses existed. A material weakness is a control deficiency, or combination of control deficiencies, in internal 
control over financial reporting such that there is a reasonable possibility that a material misstatement of the annual consolidated 
financial statements will not be prevented or detected on a timely basis. The material weaknesses identified as of December 31, 2017 
were: 

a) We did not design, establish and maintain effective procedures to ensure adequate review, approval, and existence of 

sufficient supporting documentation over manual journal entries. This weakness could impact in a failure to timely detect the 
totality of manual journal entries, as well as their adequate approval and revision. 

b) We did not design, establish or maintain effective controls over the communication of activity that impacted the judicial 
deposits and contingencies balances. Further, effective controls over the timely reconciliation of these accounts were not 
established or maintained. 

c) We did not design, establish or maintain effective control over the preparation, timely review, and documented approval of 
the reconciliation of unbilled revenues. Specifically, we did not have effective controls over the completeness and accuracy 
of supporting schedules. The schedules and historical information used in this process were not reviewed in a periodic and 
timely manner. 

d) We did not have sufficient and skilled accounting and finance personnel necessary to perform appropriate processes and 
controls related to the preparation of the financial statements in accordance with U.S. GAAP, which includes timely 
identification and review of significant non-routine transactions. As a result, a number of errors in our financial statements 
were detected and corrected and could not be detected on a timely basis by management in the normal course of the business. 

e) We did not design, establish or maintain effective control over the completeness and accuracy of consolidation entries, which 

includes timely review of reconciliation of intercompany balances and its elimination in the consolidation process. 

f) We did not design, establish or maintain effective control over the process level control to capture and identify the statute of 

limitation of its recoverable taxes.

These deficiencies resulted in material misstatements to the Company’s financial statements for 2015 and previous years, which 
were corrected through restatement of those periods, and to the preliminary 2016 and 2017 financial statements, which were corrected 
prior to issuance. 

Our independent registered public accounting firm, KPMG Auditores Independentes, has issued an adverse opinion on the 
effectiveness of our internal control over financial reporting as of December 31, 2017 as stated in their report beginning on page F-4. 

Remediation of Material Weakness

We have implemented and continue to implement measures designed to remediate the material weaknesses and, in the short term, 

to mitigate the potential adverse effects of the material weaknesses. 

We are committed to continuing to improve our internal control processes and will continue to diligently review our financial 

reporting controls and procedures in order to ensure our compliance with the requirements of the Sarbanes-Oxley Act of 2002 and the 
related rules promulgated by the SEC. 

Actions taken and planned to be taken by management to improve the internal control over financial reporting include. 

a) We have reinforced the access granting and profile management controls to mitigate the risk of improper access. In addition, 
we intend to implement an automated tool to allow the appropriate identification, review and approval of manual journal 
entries. 

b) With the purpose of promoting the timely capture of the alterations to the status of the lawsuits and their relevant deposits, 
and also the effective impact on our records, we are structuring a set of actions mainly based on the following items: 

○

○

○

○

○

Centralize the back office areas; 

Standardize procedures; 

Implement automated controls, and improve the interfaces between all systems considered in this process; 

Create an internal governance structure for periodic monitoring of inconsistencies arising from conciliation activities, 
with subsequent treatment of actions; and 

Negotiate with banks to improve the accuracy of information. 

c) We are implementing a process of periodic review of the estimates and parameters used to compose the unbilled revenues 

provision. In addition, we are planning to implement a multidisciplinary management review process, to periodically perform 
the analysis and reconciliation of those accounts. 

d) We plan to possibly hire additional senior level accounting personnel for our U.S. GAAP managing function to allow U.S. 
GAAP executives to perform higher level review duties timely, enhancing timely internal reviews of our U.S. GAAP 
financial statements, including clarifying roles and accountabilities, implementing additional prevent and detect controls, 
providing additional staff training, and other procedures, to improve the interim and annual financial statement closing 
process. 

e)

In 2013, we started an automatization process called “Dupla Contabilização” (Double Accounting) with the purpose of 
automating and standardizing the registration of expense / accounts payable with the registration of revenue / accounts 
receivable. This project entered into operation in August 2016, but it showed some failures, and at this moment, we have this 
activity partially performed and the resource under correction of failures. We expect that by the end of 2018 we will have all 
the failures corrected and 100% of invoices issued through our official invoicing systems with revenue / accounts receivable 
and expenses / accounts payable in automated manner. In addition, we are reinforcing our procedures of reconciliation to 
ensure that it occurs in a timely manner. 

f) We will strengthen the controls of managerial revision, through the implementation of a multidisciplinary structure of review 

for tax recoverable balances. In addition, we will revise and reformulate our policies and procedures, in order to ensure that 
these amounts be effectively considered and timely reviewed.

Changes in Internal Control over Financial Reporting

Other than as set forth above, there have been no changes in our internal controls over financial reporting that occurred during the 

year ended December 31, 2017 that have materially affected or are reasonably likely to materially affect our internal control over 
financial reporting as of December 31, 2017. 

ITEM 16A.AUDIT COMMITTEE FINANCIAL EXPERT 

Oi’s fiscal council currently includes an “audit committee financial expert” within the meaning of this Item 16A. Oi’s fiscal 
council has determined that Álvaro Bandeira is Oi’s fiscal council financial expert. Mr. Bandeira’s biographical information is included 
in “Item 6. Directors, Senior Management and Employees.” Mr. Bandeira is independent, as that term is defined in Rule 303A.02 of the 
New York Stock Exchange’s Listed Company Manual. 

ITEM 16B.CODE OF ETHICS 

We have adopted a code of ethics that applies to members of Oi’s board of directors, fiscal council and board of executive 

officers, as well as to our other employees. 

A copy of our code of ethics may be found on Oi’s website at http://ri.oi.com.br/conteudo_en.asp?

Pre-Approval Policies and Procedures 

Oi’s fiscal council and board of directors have approved an Audit and Non-Audit Services Pre-Approval Policy that sets forth the 
procedures and the conditions pursuant to which services proposed to be performed by Oi’s independent auditors may be pre-approved. 
This policy is designed to (1) provide both general pre-approval of certain types of services through the use of an annually established 
schedule setting forth the types of services that have already been pre-approved for a certain year and, with respect to services not 
included in an annual schedule, special pre-approval of services on a case-by-case basis by Oi’s fiscal council and Oi’s board of 
directors, and (2) assess compliance with the pre-approval policies and procedures. Oi’s management periodically reports to Oi’s fiscal 
council the nature and scope of audit and non-audit services rendered by Oi’s independent auditors and is also required to report to Oi’s 
fiscal council any breach of this policy of which Oi’s management is aware.

ITEM 16D.EXEMPTIONS FROM THE LISTING STANDARDS FOR AUDIT COMMITTEES 

Oi is relying on the general exemption from the listing standards relating to audit committees contained in Rule 10A-3(c)(3) under 

the Exchange Act for the following reasons: 

•

•

•

•

•

•

•

Oi is a foreign private issuer that has a fiscal council, which is a board of auditors (or similar body) established and selected 
pursuant to and as expressly permitted under Brazilian law; 

Brazilian law requires Oi’s fiscal council to be separate from Oi’s board of directors; 

members of Oi’s fiscal council are not elected by Oi’s management, and none of Oi’s executive officers is a member of Oi’s 
fiscal council; 

Brazilian law provides standards for the independence of Oi’s fiscal council from Oi’s management; 

Oi’s fiscal council, in accordance with its charter, makes recommendations to Oi’s board of directors regarding the 
appointment, retention and oversight of the work of any registered public accounting firm engaged (including, the 
intermediation of disagreements between Oi’s management and Oi’s independent auditors regarding financial reporting) for 
the purpose of preparing or issuing an audit report or performing other audit, review or attestation services for Oi, as 
Brazilian law requires that Oi’s board of directors appoint, retain and oversee the work of Oi’s independent public 
accountants; 

Oi’s fiscal council (1) has implemented procedures for receiving, retaining and addressing complaints regarding accounting, 
internal control and auditing matters, including the submission of confidential, anonymous complaints from employees 
regarding questionable accounting or auditing, and (2) has authority to engage independent counsel and other advisors as it 
determines necessary to carry out its duties; and 

Oi compensates its independent auditors and any outside advisors hired by Oi’s fiscal council and provides funding for 
ordinary administrative expenses incurred by the fiscal council in the course of its duties. 

Oi, however, do not believe that its reliance on this general exemption will materially adversely affect the ability of its fiscal 
council to act independently and to satisfy the other requirements of the listing standards relating to audit committees contained in Rule 
10A-3 under the Exchange Act. 

ITEM 16E.PURCHASES OF EQUITY SECURITIES BY THE ISSUER AND AFFILIATED PURCHASERS 

Not Applicable. 

ITEM 16F. CHANGE IN REGISTRANT’S CERTIFYING ACCOUNTANT 

Not Applicable. 

ITEM 16G.CORPORATE GOVERNANCE 

According to the corporate governance rules of the NYSE, foreign private issuers that are listed on the NYSE, such as Oi, are 

subject to a more limited set of corporate governance requirements than those imposed on U.S. domestic issuers. As a foreign private 
issuer, Oi must comply with the following four requirements imposed by the NYSE: 

•

•

•

•

Oi must satisfy the audit committee requirements of Rule 10A-3 under the Exchange Act; 

Oi’s Chief Executive Officer must promptly notify the NYSE in writing if any executive officer of Oi becomes aware of any 
material non-compliance with any of the applicable NYSE corporate governance rules; 

Oi must provide a brief description of any significant ways in which Oi’s corporate governance practices differ from those 
required to be followed by U.S. domestic issuers under the NYSE corporate governance rules; and 

Oi must submit an executed written affirmation annually to the NYSE and an interim written affirmation to the NYSE each 
time a change occurs to Oi’s board of directors or any committees of Oi’s board of directors that are subject to section 303A, 
in each case in the form specified by the NYSE.

Significant Differences 

The significant differences between Oi’s corporate governance practices and the NYSE’s corporate governance standards are 

mainly due to the differences between the U.S. and Brazilian legal systems. Oi must comply with the corporate governance standards 
set forth under the Brazilian Corporate Law, the rules of the CVM and the applicable rules of the B3, as well as those set forth in Oi’s 
by-laws. 

The significant differences between Oi’s corporate governance practices and the NYSE’s corporate governance standards are set 

forth below. 

Independence of Directors and Independence Tests 

In general, the NYSE corporate governance standards require listed companies to have a majority of independent directors and set 

forth the principals by which a listed company can determine whether a director is independent. In general, listed companies are 
required to comply with the following NYSE corporate governance standards: 

•

•

•

have a majority of independent directors; 

have a nominating/corporate governance committee composed of independent directors with a charter that complies with the 
NYSE corporate governance rules; and 

have a compensation committee composed of independent directors with a charter that complies with the NYSE corporate 
governance rules. 

Although Brazilian Corporate Law and Oi’s by-laws establish rules in relation to certain qualification requirements of its directors, 

neither Brazilian Corporate Law nor Oi’s by-laws require that Oi have a majority of independent directors nor require Oi’s board of 
directors or management to test the independence of Oi’s directors before such directors are appointed. 

Executive Sessions 

The NYSE corporate governance standards require non-management directors of a listed company to meet at regularly scheduled 

executive sessions without management. 

According to the Brazilian Corporate Law, up to one-third of the members of Oi’s board of directors can be elected to 
management positions. The remaining non-management directors are not expressly empowered to serve as a check on Oi’s 
management, and there is no requirement that those directors meet regularly without management. Notwithstanding the foregoing, Oi’s 
board of directors consists entirely of non-management directors; therefore Oi believes it would be in compliance with this NYSE 
corporate governance standard. 

Nominating/Corporate Governance and Compensation Committees 

The NYSE corporate governance standards require that a listed company have a nomination/corporate governance committee and 

a compensation committee, each composed entirely of independent directors and each with a written charter that addresses certain 
duties. 

Although not required under Brazilian law, Oi has a People, Designation and Compensation Committee to assist its board of 
directors, with the purpose of (1) supervising human resources strategies and attracting and retaining talent for Oi and its subsidiaries 
and matters related to the organizational structure; (2) monitoring the succession program, the processes of selecting members of the 
management bodies and internal committees and special programs for human resources, at the discretion of the chairman of the board of 
directors; (3) analyzing and defining the total remuneration strategy and evaluating the performance of the members of the 
administrative bodies and the internal committees and the employees of Oi and its subsidiaries; and (4) making an annual evaluation of 
performance, based on defined goals, of the members of the administrative bodies and internal committees of Oi.

Although not required under Brazilian law, Oi has a Corporate Governance and Finance Committee to assist its board of directors, 

with the purpose of: (1) monitoring the policies for corporate governance, maintaining the level of governance adopted by Oi and 
ensuring the effective adoption of best practices; (2) monitoring the principles and practices of conduct of Oi and its subsidiaries; 
(3) monitoring compliance with the directives established in the Listing Regulations of the Level 1 of the B3 and other policies adopted 
by Oi, as well as other applicable legislation, regulations and foreign good practices, including, among others, conditions for 
maintaining Oi’s listing on the NYSE; and (4) supervising financial and tax planning, the annual budget, the financial performance of 
the business and various financial matters at the discretion of the chairman of the board of directors, at the level of Oi and of its 
subsidiaries. 

Oi believes that these committees substantially serve the functions of the committees required under NYSE corporate governance 

standards, although the terms of reference of these committees may not include each of the duties required under the NYSE corporate 
governance standards. 

Audit Committee and Audit Committee Additional Requirements 

The NYSE corporate governance standards require that a listed company have an audit committee with a written charter that 
addresses certain specified duties and that is composed of at least three members, all of whom satisfy the independence requirements of 
Rule 10A-3 under the Exchange Act and section 303A.02 of the NYSE’s Listed Company Manual. 

As a foreign private issuer that qualifies for the general exemption from the listing standards relating to audit committees set forth 

in Section 10A-3©(3) under the Exchange Act, Oi is not subject to the independence requirements of the NYSE corporate governance 
standards. See “Item 16D. Exemptions from the Listing Standards for Audit Committees.” 

Shareholder Approval of Equity Compensation Plans 

The NYSE corporate governance standards require that shareholders of a listed company must be given the opportunity to vote on 

all equity compensation plans and material revisions thereto, subject to certain exceptions. 

Under Brazilian Corporate Law, shareholder pre-approval is required for the adoption and revision of any equity compensation 

plans, but this decision may be delegated to the board of directors. 

Corporate Governance Guidelines 

The NYSE corporate governance standards require that a listed company must adopt and disclose corporate governance guidelines 

that address certain minimum specified standards which include: (1) director qualification standards; (2) director responsibilities; 
(3) director access to management and independent advisors; (4) director compensation; (5) director orientation and continuing 
education; (6) management succession; and (7) annual performance evaluation of the board of directors. 

Oi must comply with certain corporate governance standards set forth under Brazilian Corporate Law, CVM rules and the 

applicable rules of the B3 for Level 1 companies. See “Item 9. The Offer and Listing—Regulation of Brazilian Securities Markets” and 
“Item 9. The Offer and Listing—Trading on the B3—B3 Corporate Governance Standards.” The Level 1 rules do not require Oi to 
adopt and disclose corporate governance guidelines covering the matters set forth in the NYSE’s corporate governance standards. 
However, certain provisions of Brazilian Corporate Law that are applicable to Oi address certain aspects of director qualifications 
standards and director responsibilities.

Code of Business Conduct and Ethics 

The NYSE corporate governance standards require that a listed company must adopt and disclose a code of business conduct and 

ethics for directors, officers and employees and promptly disclose any waivers of the code for directors or officers. Each code of 
business conduct and ethics should address the following items: conflicts of interest; corporate opportunities; confidentiality; fair 
dealing; protection and proper use of company assets; compliance with laws, rules and regulations (including insider trading laws); and 
encouraging the reporting of any illegal or unethical behavior. 

Although the adoption of a code of ethics is not required by Brazilian law, Oi has adopted a code of ethics applicable to its 

directors, officers and employees, which addresses each of the items listed above. See “Item 16B. Code of Ethics.”

MANAGEMENT’S REPORT ON INTERNAL CONTROLS OVER FINANCIAL REPORTING 

Management’s Annual Report on Internal Control over Financial Reporting and Report of Independent Registered Public 
Accounting Firm 

Our management is responsible for establishing and maintaining adequate internal controls over financial reporting. 

Our internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial 
reporting and the preparation of financial statements for external purposes in accordance with applicable generally accepted accounting 
principles.  Our  internal control  over  financial  reporting includes  those policies and procedures  that  (1) pertain to  the maintenance  of 
records  that,  in  reasonable  detail,  accurately  and  fairly  reflect  the  transactions  and  dispositions  of  our  assets,  (2) provide  reasonable 
assurance  that  transactions  are  recorded  as  necessary  to  permit  preparation  of  financial  statements  in  accordance  with  applicable 
generally accepted accounting principles, and that our receipts and expenditures are being made only in accordance with authorizations 
of  our  management  and  directors,  and  (3) provide  reasonable  assurance  regarding  prevention  or  timely  detection  of  unauthorized 
acquisition, use, or disposition of our assets that could have a material effect on the financial statements. 

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections 
of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in 
conditions, or that the degree of compliance with the policies or procedures may deteriorate. 

Under  the  supervision  and  with  the  participation  of  our  CEO  and  CFO,  our  management  conducted  an  assessment  of  our  internal 
control over financial reporting as of December 31, 2017 based on the criteria established in “Internal Control—Integrated Framework 
(2013)” issued by COSO. 

As  a  result  of  management’s  assessment  of  our  internal  control  over  financial  reporting  as  of  December 31,  2017,  management 
concluded that the following material weaknesses in our internal control over financial reporting existed: 

a) We  did  not  design,  establish  and  maintain  effective  procedures  to  ensure  adequate  review,  approval,  and  existence  of 
sufficient supporting documentation over manual journal entries. This weakness could impact in a failure to timely detect the 
totality of manual journal entries, as well as their adequate approval and revision. 

b) We  did  not  design,  establish  or  maintain  effective  controls  over  the  communication  of  activity  that  impacted  the  judicial 
deposits  and  contingencies  balances.  Further,  effective  controls  over  the  timely  reconciliation  of  these  accounts  were  not 
established or maintained. 

c) We did not design, establish or maintain effective control over the preparation, timely review, and documented approval of 
the reconciliation of unbilled revenues. Specifically, we did not have effective controls over the completeness and accuracy 
of supporting schedules. The schedules and historical information used in this process were not reviewed in a periodic and 
timely manner. 

d) We  did  not  have  sufficient  and  skilled  accounting  and  finance  personnel  necessary  to  perform  appropriate  processes  and 
controls  related  to  the  preparation  of  the  financial  statements  in  accordance  with  U.S.  GAAP,  which  includes  timely 
identification and review of significant non-routine transactions. As a result, a number of errors in our financial statements 
were detected and corrected and could not be detected on a timely basis by management in the normal course of the business. 

e) We did not design, establish or maintain effective control over the completeness and accuracy of consolidation entries, which 

includes timely review of reconciliation of intercompany balances and its elimination in the consolidation process. 

f) We did not design, establish or maintain effective control over the process level control to capture and identify the statute of 

limitation of its recoverable taxes.

Because of the existence of this material weakness, management has concluded that our internal control over financial reporting was 
ineffective as of December 31, 2017. 

The effectiveness of our internal control over financial reporting has been audited by KPMG Auditores Independentes as stated in their 
report included in this Annual Report on Form 20-F, which expresses an adverse opinion on the effectiveness of our internal control 
over  financial  reporting  as  of  December 31,  2017.  Ours  independent  registered  public  accountants,  KPMG  Auditores  Independentes, 
audited  the  consolidated  financial  statements  included  in  this  Annual  Report  on  Form  20-F,  and  their  adverse  opinion  on  the 
effectiveness of our internal control did not affect their audit report to our financial statements.

Report of Independent Registered Public Accounting Firm 

To the Stockholders and Board of Directors of Oi S.A.—Under Judicial Reorganization—Debtor-in-possession 

Opinion on Internal Control Over Financial Reporting 

We have audited Oi S.A. – Under Judicial Reorganization – Debtor-in-possession and subsidiaries (the Company) internal control over 
financial reporting as of December 31, 2017, based on criteria established in Internal Control—Integrated Framework (2013) issued by 
the  Committee  of  Sponsoring  Organizations  of  the  Treadway  Commission.  In  our  opinion,  because  of  the  effect  of  those  material 
weaknesses, described below, on the achievement of the objectives of the control criteria, the Company has not maintained effective 
internal  control  over  financial  reporting  as  of  December 31,  2017,  based  on  criteria  established  in  Internal  Control—Integrated 
Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. 

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), 
the consolidated balance sheets of the Company as of December 31, 2017 and 2016, the related consolidated statements of operations, 
comprehensive loss, stockholders’ equity, and cash flows for each of the years in the three-year period ended December 31, 2017, and 
the  related  notes  (collectively,  the  consolidated  financial  statements),  and  our  report  dated  May 15,  2018  expressed  an  unqualified 
opinion on those consolidated financial statements. 

A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a 
reasonable  possibility  that  a  material  misstatement  of  the  company’s  annual  or  interim  financial  statements  will  not  be  prevented  or 
detected on a timely basis. The material weaknesses described below have been identified and included in management’s assessment: 

•

•

The Company did not design, establish and maintain effective procedures to ensure adequate review, approval, and existence of 
sufficient supporting documentation over manual journal entries. 

The Company did not design, establish or maintain effective controls over the communication of activity that impacted the judicial 
deposits  and  contingencies  balances.  Further,  effective  controls  over  the  timely  reconciliation  of  these  accounts  were  not 
established or maintained.

The  Company  did  not  design,  establish  or  maintain  effective  control  over  the  preparation,  timely  review,  and  documented 
approval  of  the  reconciliation  of  unbilled  revenues.  Specifically,  the  Company  did  not  have  effective  controls  over  the 
completeness and accuracy of supporting schedules. 

The Company did not have sufficient and skilled accounting and finance personnel necessary to perform appropriate processes and 
controls  related  to  the  preparation  of  the  financial  statements  in  accordance  with  U.S.  generally  accepted  accounting  principles 
(“US GAAP”), which includes timely identification and review of significant non-routine transactions. 

The Company did not design, establish or maintain effective control over the completeness and accuracy of consolidation entries, 
which includes timely review of reconciliation of intercompany balances and its elimination in the consolidation process. 

The  Company  did  not  design,  establish  or  maintain  effective  control  over  the  process  level  control  to  capture  and  identify  the 
statute of limitation of its recoverable taxes. 

These deficiencies resulted in material misstatements to the Company’s financial statements for 2015 and previous years which were 
corrected through restatement of those periods, and to the preliminary 2016 and 2017 financial statements, which were corrected prior 
to issuance. 

These material weaknesses were considered in determining the nature, timing, and extent of audit tests applied in our audit of the 2017 
consolidated financial statements, and this report does not affect our report on those consolidated financial statements. 

Basis for Opinion 

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of 
the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control 
Over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based 
on  our  audit.  We  are  a  public  accounting  firm  registered  with  the  PCAOB  and  are  required  to  be  independent  with  respect  to  the 
Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange 
Commission and the PCAOB. 

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to 
obtain reasonable assurance about  whether  effective  internal  control over  financial  reporting was maintained in all material respects. 
Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, 
assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control 
based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. 
We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control Over Financial Reporting 

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of 
financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting 
principles.  A  company’s  internal  control  over  financial  reporting  includes  those  policies  and  procedures  that  (1) pertain  to  the 
maintenance  of  records  that,  in  reasonable  detail,  accurately  and  fairly  reflect  the  transactions  and  dispositions  of  the  assets  of  the 
company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in 
accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in 
accordance  with  authorizations  of  management  and  directors  of  the  company;  and  (3) provide  reasonable  assurance  regarding 
prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect 
on the financial statements. 

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections 
of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in 
conditions, or that the degree of compliance with the policies or procedures may deteriorate. 

Disclaimer on Additional Information in Management’s Report 

We  do  not  express  an  opinion  or  any  other  form  of  assurance  on  management’s  statements,  included  in  the  accompanying 
Management’s  Report  on  Internal  Control  Over  Financial  Reporting,  referring  to  corrective  actions  taken  after  December 31,  2017, 
relative to the aforementioned material weaknesses in internal control over financial reporting.

principles.

The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern. 
As discussed in Note 1 to the consolidated financial statements, the Company has suffered recurring losses from operations, has a net 
capital deficit and net shareholders’ deficit, and needs to achieve the conditions of the judicial reorganization plan which include: (a) the 
conversion of the debt into equity of the qualified bondholders’ credits and (b) a capital increase in the amount of $4 billion Reais (local 
currency)  via  a  public  offering.  These  events  or  conditions  raise  substantial  doubt  about  its  ability  to  continue  as  a  going  concern. 
Management’s plans in regard to these matters are also described in Note 1. The consolidated financial statements do not include any 
adjustments that might result from the outcome of this uncertainty.

Basis for Opinion 

These  consolidated  financial  statements  are  the  responsibility  of  the  Company’s  management.  Our  responsibility  is  to  express  an 
opinion  on  these  consolidated  financial  statements  based  on  our  audits.  We  are  a  public  accounting  firm  registered  with  the  Public 
Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in 
accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission 
and the PCAOB. 

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to 
obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error 
or  fraud.  Our  audits  included  performing  procedures  to  assess  the  risks  of  material  misstatement  of  the  consolidated  financial 
statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, 
on  a  test  basis,  evidence  regarding  the  amounts  and  disclosures  in  the  consolidated  financial  statements.  Our  audits  also  included 
evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation 
of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.

We have served as the Company’s auditor since 2012.

Oi S.A. – Under Judicial Reorganization – Debtor-in-Possession and Subsidiaries 

Notes to the Consolidated Financial Statements 

(Amounts in thousands of Brazilian reais - R$, unless otherwise stated) 

1.       BASIS OF PRESENTATION 

Oi  S.A. -  Under  Judicial  Reorganization –  Debtor-in-Possession (“Company”  or  “Oi”), is  a Switched  Fixed-line Telephony Services 
(“STFC”) concessionaire, operating since July 1998 in Region II of the General Concession Plan (“PGO”), which covers the Brazilian 
states of Acre, Rondônia, Mato Grosso, Mato Grosso do Sul, Tocantins, Goiás, Paraná, Santa Catarina and Rio Grande do Sul, and the 
Federal District, in the provision of STFC as a local and intraregional long-distance carrier. From January 2004 on, the Company also 
provides  domestic  and  international  long-distance  services  in  all  Regions  and  since  January  2005  started  to  provide  local  services 
outside  Region  II.  These  services  are  provided  under  concessions  granted  by  Agência  Nacional  de  Telecomunicações—ANATEL 
(National Telecommunications Agency), the regulator of the Brazilian telecommunications industry (“ANATEL” or “Agency”). 

The Company is headquartered in Brazil, in the city of Rio de Janeiro, at Rua do Lavradio, 71 – 2º andar. 

The  Company  also  holds:  (i) through  its  wholly-owned  subsidiary  Telemar  Norte  Leste  S.A.  -  Under  Judicial  Reorganization  – 
Debtor-in-Possession  (“Telemar”)  a  concession  to  provide  fixed  telephone  services  in  Region  I  and  nationwide  International  Long-
distance services; and (ii) through its indirect subsidiary Oi Móvel S.A. - Under Judicial Reorganization – Debtor-in-Possession (“Oi 
Móvel”) a license to provide mobile telephony services in Region I, II and III. 

The  local  and  nationwide  STFC  long-distance  concession  agreements  entered  into  by  the  Company  and  its  subsidiary  Telemar  with 
ANATEL are effective until December 31, 2025. These concession agreements provide for reviews on a five-year basis and in general 
have a higher degree of intervention in the management of the business than the licenses to provide private services, and also include 
several consumer protection provisions, as perceived by the regulator. On December 30, 2015, ANATEL announced that the review to 
be implemented by the end of 2015 had been postponed to April 30, 2016. Subsequently, On April 29, 2016, ANATEL decided, under a 
Resolution Circular Letter, to postpone until December 31, 2016 the execution of the revised agreements. On December 30, 2016 and 
under a Resolution Circular Letter, ANATEL postponed again the execution of the new concession agreements up to June 30, 2017. On 
June 29,  2017,  ANATEL  informed,  in  an  official  letter,  that  it  would  no  longer  make  any  further  amendments  to  the  concession 
agreements at this instance. Note that until the end of the concession agreement on December 31, 2025 there would still be a period for 
revision,  on  December 31,  2020.  It  is  worth  noting  that  Congress  Bill  79/2016  provides  for  a  special  amendment  of  concession 
agreements to adjust them to the possibility of migrating from a public utility regime to an STFC service provision under a private law 
regime. Thus,  if this bill is  passed into law, the concession agreement is subject to  amendment in any date other than December 31, 
2020. Throughout the years, ANATEL initiated some procedures aiming at monitoring the Company’s financial situation, as well as to 
assess the Company’s ability to discharge its obligations arising from the terms of the concession agreements. In light of the approval of 
the Judicial Reorganization Plan by the creditors and its subsequent ratification by the competent court ANATEL started to monitor the 
Oi Group Companies’ operating and financial positions based on the effectiveness of said Judicial Reorganization Plan (JRP).

JUDICIAL REORGANIZATION 

On June 20, 2016, Oi, together with its direct and indirect wholly owned subsidiaries Oi Móvel, Telemar, Copart 4 Participações S.A. – 
Under  Judicial  Reorganization  -  Debtor-in-Possession  (“Copart  4”),  Copart  5  Participações  S.A.  –  Under  Judicial  Reorganization  - 
Debtor-in-Possession 
- 
Debtor-in-Possession (“PTIF”), and Oi Brasil Holdings Cooperatief U.A. – Under Judicial Reorganization—Debtor-in-Possession (“Oi 
Holanda”) (collectively with the Company, the “Oi Companies” or “RJ Debtors”) filed, as a matter of urgency, a request for judicial 
reorganization  with  the  Court  of  the  State  of  Rio  de  Janeiro,  as  approved  by  the  Company’s  Board  of  Directors  and  the  competent 
governing bodies. 

International  Finance  B.V.  –  Under  Judicial  Reorganization 

(“Copart  5”),  Portugal  Telecom 

As broadly disclosed to the market, the Company had been taking actions and conducting studies, together with its financial and legal 
advisors  to  optimize  its  liquidity  and  debt  profile.  The  Company,  after  considering  the  challenges  arising  from  its  economical  and 
financial situation and in light of the maturity schedule of its financial debts, threats to cash flows represented by imminent block or 
pledge of amounts in lawsuits, and in light of the urgency to adopt protection measures of the Oi Companies, concluded that the request 
for judicial reorganization was the most appropriate course of action at that time to (i) preserve the continuity of its offering of quality 
services  to  its  customers,  within  the  rules  and  commitments  undertaken  with  the  Brazilian  National  Telecommunications  Agency 
(ANATEL),  (ii)  preserve  the  value  of  the  Oi  Companies,  (iii) maintain  the  continuity  of  operations  and  corporate  activities  in  an 
organized manner, thus protecting the interests of the Oi Companies, its customers, shareholders and other stakeholders, and (iv) protect 
the Oi Companies’ cash and cash equivalents. 

The  filing  of  the  judicial  reorganization  was  another  step  towards  the  Company’s  financial  restructuring,  who  continues  working  to 
secure  new  customers  while  maintaining  its  service  and  product  sales  to  all  market  segments,  in  all  of  its  distribution  and  customer 
service  channels.  The  installation,  maintenance  and  repair  activities  also  continue  to  be  performed  on  a  timely  basis  by  the  Oi 
Companies and their subsidiaries. All of Company’s workforce has been maintaining the work as usual, including sales, operating and 
administrative activities. Oi keeps focusing on its investments in structuring projects aimed at promoting the improvement of service 
quality to continue to bringing technological advances, high service standards, and innovation to its customers.

On June 22, 2016, the United States Bankruptcy Court for the Southern District of New York (“U.S. Bankruptcy Court”) entered an 
order granting the provisional relief requested by the Company, Telemar, Oi Holanda and Oi Móvel (all four collectively referred to as 
“Debtors”) in their United States bankruptcy code Chapter 15 cases that were filed on June 21, 2016. 

The  Provisional  Relief  prevents  creditors  from  initiating  actions  against  the  Debtors  or  their  property  located  within  the  territorial 
jurisdiction of the United States and parties from terminating their existing U.S. contracts with the Debtors. 

On  June 23,  2016,  the  High  Court  of  Justice  of  England  and  Wales  issued  orders  recognizing  the  judicial  reorganization  request  in 
respect  of  the  Company,  Telemar  and  Oi  Móvel  filed  in  Brazil  pursuant  to  Law  11101/2005,  as  a  foreign  main  proceeding  in 
accordance with the United Nations Commission on International Trade Law (UNCITRAL) Model Law on Cross-Border Insolvency, as 
set out in Schedule 1 to the Cross-Border Insolvency Regulations 2006 (S.I. 2006 No. 1030) (“Recognition Orders”). 

The Recognition Orders establish that the commencement or continuation of proceedings (including enforcement actions) in England 
and Wales relating to the Company’s, Telemar’s and Oi Móvel’s assets, rights, obligations or liabilities are stayed from June 23, 2016. 

On  June 29,  2016,  the  Judge  of  the  7th  Corporate  Court  of  the  Judicial  District  of  the  State  Capital  of  Rio  de  Janeiro  (“Judicial 
Reorganization Court”) granted the processing of the judicial reorganization of the Oi Companies. 

The decision granting the processing of the judicial reorganization of the Oi Companies determined that all the procedural time limits 
are counted in business days. To this regard, even though the decision has determined that the Judicial Reorganization Plan (“JRP” or 
“Plan”) be filed within 60 business days, the Public Prosecution Service filed an interlocutory appeal requesting that this time limit be 
counted in calendar days. In light of the interlocutory appeal filed by the Public Prosecution Service, the Judicial Reorganization Court 
revised its decision, establishing that the JRP be filed within 60 calendar days, counted from the issuance of the decision granting the 
processing of the judicial reorganization. 

On July 21, 2016, the U.S. Bankruptcy Court held a hearing to judge the Debtors’ requests and since no objection to the recognition was 
filed, the U.S. Bankruptcy Court recognized the judicial reorganization as a main foreign proceeding with regard to each of the Debtors. 
As a result of this recognition, a stay was automatically applied, preventing the filing, in the United States, of any actions against the 
Debtors or their properties located within the territorial jurisdiction of the United States and parties from terminating their existing U.S. 
contracts with the Debtors. 

On  July 22,  2016,  the judicial  reorganization  request was  ratified  by  the shareholders  at  the Company’s Extraordinary  Shareholders’ 
Meeting.

The shareholders also authorized the Company’s management to take all the actions and practice all the acts necessary with regard to 
the judicial reorganization of the Oi Companies and ratified all the actions taken up to that date. 

On  July 22,  2016,  the  Judicial  Reorganization  Court  appointed  PricewaterhouseCoopers  Assessoria  Empresarial  Ltda.  as  the  court-
appointed  financial  administrator,  and  the  law  firm  Arnoldo  Wald  to  act  as  the  court-appointed  legal  administrator  (collectively, 
“Judicial Administrator”) of the Oi Companies. 

Considering that the Judicial Reorganization Court changed the way the deadline to file the plan is counted, as referred to above, on 
September 5,  2016  the  Oi  Companies  filed  the  JRP,  which  establishes  the  terms  and  conditions  for  the  restructuring  of  the  Oi 
Companies’ debt, and the main actions that could be adopted to overcome the current financial situation of the Oi Companies and their 
continuity as going concerns, including by (i) restructuring and balancing their liabilities; (ii) prospecting and adopting actions during 
the judicial reorganization aiming to obtain new funds; and (iii) potential sale of capital assets. 

The first list of creditors submitted by the Oi Companies was published on September 20, 2016 (“First List of Creditors”). Payables to 
parties  not  controlled  by  Oi,  according  to  the  First  List  of  Creditors,  totaled  approximately  R$65.1 billion.  As  from  the  date  of  this 
publication, the creditors had fifteen (15) business days to file with the Judicial Administrator (i) a proof of claim (the “Proof of Claim” 
or “Claim”), if their receivables were not included in the First List of Creditors, or (ii) the discrepancy (the “Discrepancy”) if, according 
to the creditor, the amount in the First List of Creditors is incorrect or its credits were incorrectly classified. The deadline for creditors 
to file a Claim and/or a Discrepancy was October 11, 2016. 

On March 2, 2017, the 3rd Lisbon Commercial Court issued a decision acknowledging, with regard to Oi and Telemar, the decision that 
approved the processing of the judicial reorganization requested filed in Brazil. 

On March 22, 2017, the Company’s Board of Directors approved the basic financial conditions to be adjusted in the JRP and authorized 
the Company’s Executive Officers and advisors to file, as soon as possible, an amendment to the JRP with the Judicial Reorganization 
Court, as disclosed by Oi in a Material Fact Notice on the same date, and these conditions were presented in court on March 28, 2017. 
The amended JRP was filed with the court on October 11, 2017. 

On  March 31,  2017,  the  Judicial  Reorganization  Court  issued  a  decision  replacing  PricewaterhouseCoopers  Assessoria  Empresarial 
Ltda. as financial administrator for the BDOPro Consortium, which declined the appointment. Thus on April 10, 2017, the law Firm 
Arnoldo Wald was appointed as the sole judicial administrator of the Oi Companies’ Judicial Reorganization. 

The judicial administrator reviewed the First List of Creditors and after reviewing this List, taking into consideration the Claims and 
Discrepancies, submitted the list of creditors published in the Notice of May 29, 2017 (“List of Creditors”).

The publication of the List of Creditors set two deadlines for the creditors: (i) a ten-business day deadline to file with the Judge their 
challenges to Second List of Creditors (the “Challenge”); and (ii) a thirty-business day deadline to file with the Judge their objections to 
the Judicial Reorganization Plan (the “Objection”). 

On  August 23,  2017,  the  Judicial  Reorganization  Court  scheduled  the  date  of  the  first  Creditors’  General  Meeting  (“CGM”)  for 
October 9, 2017 (on its first notice to convene) and October 23, 2017 (on its second notice to convene). 

On  September 27,  2017,  in  light  of  the  negotiated  decisions  to  ensure  the  approval  of  the  JRP  and  the  procedural  aspects  related  to 
holding the General Creditors’ Meeting (“CGM”), which could result in changes in the voting system, the Oi Companies requested to 
the Judicial Reorganization Court the postponement of the CGM to October 23, 2017, on its first notice to convene, and November 27, 
2017,  on  its  second  notice  to  convene,  at  Riocentro.  The  Judicial  Reorganization  Court  approved  this  request  on  the  same  day, 
seconding the favorable opinions of the judicial administrator and the Rio de Janeiro State’s Public Prosecution Office. 

On October 10, 2017, the majority of the members of the Company’s Board of Directors approved the new version of the JRP. 

On October 11, 2017, the RJ Debtors filed a new, joint version of the JRP with the Judicial Reorganization Court, to be reviewed and 
approved at the CGM on the dates referred to above, as well as the report of the independent appraiser. 

On  October 20,  2017,  in  response  to  the  requests  made  by  certain  creditors,  the  Judicial  Reorganization  Court  determined  the 
postponement  of  the  GCM  for  November 6,  2017,  on  its  first  notice  to  convene,  and  November 27,  2017,  on  its  second  notice  to 
convene. 

In compliance with the provisions of Article 36 of Law 11101/2005, the Judicial Reorganization Court, in response to a request from 
the Judicial Administrator, determined the postponement of the CGM date, firstly scheduled for November 6, 2017, on its first notice to 
convene, for November 10, 2017, and maintained November 27, 2017 to hold the CGM, on its second notice to convene. 

On November 9, 2017, in response to the new requests made by certain creditors, the Judicial Reorganization Court determined once 
again the postponement of the CGM to December 7, 2017, on its first notice to convene, which may continue on December 8, 2017, if 
necessary, and February 1, 2018, on its second notice to convene, which may continue on February 2, 2018, if necessary. 

Again,  on  November 29,  2017,  the  Judicial  Reorganization  Court  determined  once  again  the  postponement  of  the  CGM  to 
December 19, 2017, on its first notice to convene, which may continue on December 20, 2017, if necessary, and February 1, 2018, on 
its second notice to convene, which may continue on February 2, 2018, if necessary. 

On December 19, 2017, after confirming that the required quorum of classes I, II, III, and IV creditors was in attendance, the CGM was 
held and the JRP was approved by a vast majority of creditors on December 20, 2017.

On January 8, 2018, the Judicial Reorganization Court issued a decision that ratifies the JRP and grants the judicial reorganization to the 
Oi Companies. Said decision was published on February 5, 2018, initiating the period for the creditors of the RJ Debtors to elect one of 
the payment options to recover their claims, as provided for in the JRP, which ended on February 26, 2018, except for bondholders, 
whose deadline was extended to March 8, 2018, as decided by the Judicial Reorganization Court on February 26, 2018. 

In the course of the preparation of the JRP, the Company assessed a significant set of scenarios and forecasts for the evolution of its 
operations and financial, and conducted discussions with creditors and partners affected by the JRP. This preparatory work was in line 
with  the  complexity  and  sheer  size  of  the  Company’s  business,  the  existing  high  number  of  operating  and  financial  processes  and 
controls with an impact on the assumptions used by Management, and the volume and diversity of the information used. 

The Company’s management identified, during the preparation of the JRP, that there were weaknesses in some of these processes and 
controls and an opportunity to obtain further information from the entities involved in the process. 

In light of the identification of weaknesses in controls, the Company’s management immediately took the necessary actions to measure 
possible impacts of the JRP on cash flows and the Company’s historic financial statements, namely with regard to the realizable value 
of  assets.  In  a  short  period  of  time,  Management  initiated  the  procedures  aimed  at  identifying  the  root  cause  of  the  weaknesses,  the 
design, and the implementation, within a short and, appropriate time horizon, of new and improved controls. Finally, this work allowed 
Management  to  conclude  that  there  should  not  be  any  impact  on  the  Judicial  Reorganization  Plan’s  Cash  Flows  and  make  the 
corresponding corrections of accounting errors (Note 2). 

The prepetition liabilities subjected to compromise will be recovered by the creditors in accordance with the JRP approved at the CGM 
on  December 19  and  20,  2017  and  ratified  by  the  Judicial  Administrator  Court  on  January 8,  2018,  which  was  submitted  on 
December 22,  2017  by  the  Trustee,  in  the  records  of  digital  case  No. 0203711-65.2016.8.19.0001,  available  for  consultation  on  the 
Company’s website (www.recjud.com.br) and the Court of Justice’s website (www.tjrj.jus.br). : 

Creditors Settlement Program 

On June 23, 2017, the Company disclosed a Notice to the Market informing that, as authorized by the Judicial Reorganization Court, 
the  Company  was  going  to  initiate  a  program  to  enter  into  settlements  with  the  Oi  Companies’  creditors  listed  in  the  Judicial 
Administrator’s  List  of  Creditors,  published  on  May 29,  2017  (“Oi  Creditor”  and  “Creditors  Settlement  Program”  or  “Program”, 
respectively), and creditors could join the program via the website www.credor.oi.com.br. 

The  Creditors  Settlement  Program  was  applicable  for  creditors  with  claims  amounting  to  R$50,000  or  lower,  and  allowed  the 
prepayment of 90% of the claim on the acceptance of the creditor and the remaining 10% of the claim after the approval of the JRP, to 
be  paid  under  the  terms  and  conditions  of  the  Creditors  Settlement  Program.  A  Oi  Creditor  whose  claim  was  higher  than  R$50,000 
would be

entitled to join the Creditors Settlement Program, in which case they would receive a R$50,000 prepayment, upon acceptance by such 
Oi Creditor of the settlement under the terms and conditions set out in the Creditors Settlement Program and the exceeding amount will 
be  paid  as  set  out  in  the  Plan.  The  Creditors  Settlement  Program  benefited  the  participating  Oi  Creditors  as  it  allowed  for  the 
prepayment of part of the amount under the Program. 

The Program was temporarily suspended by force of a judicial decision but on August 29, 2017 the Rio de Janeiro State Court of Justice 
overturned this decision and upheld the validity of the Creditors Settlement Program. Accordingly, the Creditors Settlement Program 
was implemented as from this date, and ended in December 8, 2017. 

Approximately 35,000 creditors jointed the Creditors Settlement Program, of which about 30,000 in Brazil and 5,000 in Portugal, and 
approximately R$360 million were made available for the prepayment of the settlements entered into under the Program. 

Pre-petition Claims, Regulatory Agencies 

The Company has reported that it has knowledge of regulatory punitive administrative proceedings and lawsuits that could amount to 
approximately R$14.5 billion as at June 30, 2016, including fines imposed, expected fines to be  imposed and corresponding inflation 
adjustments. The Company disagrees and is challenging a material portion of the noncompliance events pointed out by ANATEL and it 
is also challenging the disproportionateness of the punitive actions taken, emphasizing their unreasonableness. 

It  is  worth  noting  that  in  the  context  of  the  judicial  reorganization  of  the  Oi  Companies,  ANATEL  challenged,  amongst  others,  the 
decision that approved the processing of the judicial reorganization, as well as the beginning of a mediation proceeding between the RJ 
Debtors and itself, by filing bills of review No. 0043065-84.2016.8.19.0000 and No. 0060963-13.2016.8.19.0000. As for bill of review 
No. 0043065-84.2016.8.19.0000, filed against the decision that approved the processing of the judicial reorganization, this appeal found 
that ANATEL’s credits are subject to the reorganization. The interlocutory appeal filed against the mediation proceeding between the 
RJ  Debtors  and  ANATEL  is  still  pending  trial.  Notwithstanding,  in  light  of  the  lack  of  interest  of  ANATEL  in  this  mediation 
proceeding, on February 26, 2018 the 7th Corporate Court of the Rio de Janeiro State Court of Justice issued a decision where it rules 
the suspension of the mediation proceeding between ANATEL and the Company. 

It  is  worth  noting  that  ANATEL  also  challenged  the  submission  of  its  claims  to  the  judicial  reorganization  proceeding,  by  filing 
interlocutory  appeal  No. 0057446-63.2017.8.19.0000  against  the  decision  issued  on  its  claim  Challenge  case,  in  which  the  Judicial 
Reorganization  Court  reaffirms  the  understanding  on  the  pre-petition  nature  of  the  regulator’s  nontax  claims.  In  his  judgment  of  the 
advanced  relief  request  filed  by  ANATEL,  State  Justice  Cezar  Augusto  Rodrigues  Costa,  reporting  judge  at  the  time,  decided  to 
maintain  such  claims  under  the  Judicial  Reorganization  Court  and  granted  partial  suspensory  effect  to  determine  the  exclusion  of 
possible tax claims assigned to ANATEL, as well as the statutory charges arising on their collection and the related punitive fines for 
tax infractions. Currently, the Company is awaiting a decision on the Interlocutory appeal filed

by ANATEL against this decision and the judgment of the appeal merits by the 8th Civil Court. In addition Justice Marco Buzzi, from 
the Superior Court of Justice decided, in the context of Conflict of Competence No. 154.977/RJ, based on the opinion of the Federal 
Public  Prosecution  Office,  to  acknowledge  that  the  submission  of  ANATEL  claims  must  be  discussed  in  the  context  of  the  Judicial 
Reorganization, using the appropriate appeal. 

In addition to the appeals referred to above, ANATEL filed interlocutory appeal No. 0048971-21.2017.8.19.0000 against the decision 
issued  on  its  objection  to  the  judicial  reorganization  plan  without  judgment  on  the  objection’s  merits.  As  a  result  of  this appeal,  the 
requested suspensory effect was partially upheld by State Justice Cezar Augusto, from the 8th Civil Chamber of the Rio de Janeiro State 
Court of Justice, by suspending the enforcement of Clauses 4.3.2.8 and Sub-clauses 4.3.2.8.1 and 4.3.2.8.2 of the JRP that had been 
filed by the RJ Debtors in what they concern ANATEL. Said clauses address the payment of ANATEL’s pre-petition claims and the 
initiation  of  the  mediation  between  the  RJ  Debtors  and  ANATEL.  Oi,  however,  changed  the  terms  of  the  JRP,  which  maintains  the 
treatment of ANATEL claims as pre-petition claims and was approved by a vast majority of creditors at the Creditors’ General Meeting 
on December 19 and 20, 2017, and ratified by the 7th Corporate Court of the Rio de Janeiro State Court of Justice on January 8, 2018.

the 

The JRP submitted to and approved at the CGM on December 20, 2017, which was ratified by the Judicial Reorganization Court on 
January 8, 2018, lays down the payment method Pre-petition Claims, Regulatory Agencies, which include ANATEL’s non-tax claims 
amounting to approximately R$14.5 billion as of June 30, 2016: 

(i)

Payment of nontax pre-petition claims that are under the jurisdiction of the Federal Attorney General’s Office (AGU) in two 
hundred forty (240) installments, commencing June 30, 2018, as follows: (i) from the 1st to the 60th installment: 0.160%; (ii) 
from the 61st to the 120th installment: 0.330%; (iii) from the 121st to the 180th installment: 0.500%; (iv) from the 181st to the 
239th installment:  0.660%; and  (v)  240th  installment:  the outstanding  balance.  The  first  installments  shall  be  fully  paid  by 
cashing  amounts  initially  deposited  in  courts  as  collateral  of  these  claims,  to  be  supplemented,  if  necessary,  in  cash. 
Beginning in the subsequent month, Oi shall pay the other installments in cash. As from the second installment, the monthly 
installments shall be adjusted for inflation using the SELIC (Central Bank’s policy rate); 

Because the other nontax pre-petition claims of regulatory agencies challenged at the administrative level are illiquid up to this date, 
they shall be paid as laid down in Clause 4.3.6 of the JRP, general payment method of unsecure claims. 

The Plan also  provides for  the  possibility of the  Company adopting a general statutory rule to be published  in  the future in order  to 
regulate the non-tax claims of regulatory agencies subject to the Judicial Reorganization.

Note,  however,  that  ANATEL  filed  interlocutory  appeal  No. 001068-32.2018.8.19.0000  against  the  decision  that  ratified  the  judicial

Liabilities subject to compromise (Note 28) 

As a result of the filing of the Bankruptcy Petitions, the company has applied the FASB Accounting Standards Codification (“ASC”) 
852  Reorganizations  in  preparing  its  consolidated  financial  statements.  ASC  852  requires  that  financial  statements  distinguish 
transactions and events that are directly associated with the reorganization from the ongoing operations of the business. Accordingly, 
certain  expenses,  realized  gains  and  losses  and  provisions  for  losses  that  are  realized  or  incurred  in  the  judicial  reorganization 
proceedings have been recorded in a reorganization line item in its consolidated statements of operations. In addition, the prepetition 
obligations  that  may  be  impacted  by  the  judicial  reorganization  proceedings  have  been  classified  on  the  balance  sheet  as  liabilities 
subject to compromise. These liabilities are reported as the amounts expected to be allowed by the Judicial Reorganization Court, even 
if they may be settled for lesser amounts. 

In connection with an emergence from the Judicial Reorganization Cases, the Company may be required to adopt fresh start accounting, 
upon  which  the  Company’s  assets  and  liabilities  will  be  recorded  at  their  fair  value.  The  fair  values  of  the  Company’s  assets  and 
liabilities  as  of  that  date  may  differ  materially  from  the  recorded  values  of  its  assets  and  liabilities  as  reflected  in  its  historical 
consolidated  financial  statements.  In  addition,  the  Company’s  adoption  of  fresh  start  accounting  may  materially  affect  its  results  of 
operations following the fresh start reporting dates as the Company may have a new basis in its assets and liabilities. Consequently, the 
Company’s  financial  statements  may  not  be  comparable  with  the  financial  statements  prior  to  that  date  and  the  historical  financial 
statements  may  not  be  reliable  indicators  of its  financial  condition  and  results  of  operations  for  any  period  after it adopts  fresh  start 
accounting. The Company is in the process of evaluating the potential impact of the fresh start accounting on its consolidated financial 
statements, which is not possible to conclude at the moment due to the pending swap of claims by equity, necessary for the conclusion 
of the mentioned fresh start accounting.

(“PT  Portugal”)  shares,  which  held  all  the  (i.a)  operating  assets  of  Pharol  amounting  to  R$30,299  (mostly  represented  by 
available-for-sale  securities,  tangible  and  intangible  assets),  except  its  direct  or  indirect  interests  in  the  Company  and  in  Contax

the following former PT Group subsidiaries: 

(i)

100%  of  the  shares  of  PT  Participações  SGPS,  S.A.  (“PT  Participações”),  holding  of  the  operations  in  Africa,  through

Corporate reorganization 

On March 31, 2015, the shareholders of TmarPart acting at a pre-meeting of the shareholders of TmarPart (1) unanimously approved 
the adoption of an alternative share structure, after analyzing options and taking into consideration the obstacles to the completion of the 
previously announced merger of shares of Oi and TmarPart, and (2) authorized the managements of TmarPart and Oi to begin taking the 
applicable  steps  to  implement  the  alternative  share  structure.  The  alternative  share  structure  was  intended  to  achieve  many  of  the 
primary purposes of the merger of shares of Oi and TmarPart, including the adoption by the company of the best corporate governance 
practices  required  by  BM&FBovespa’s  Novo  Mercado  segment  and  the  elimination  of  the  control  of  Oi  through  the  various 
shareholders’ agreements governing Oi, while maintaining the goal of implementing a transaction that would result in the listing of the 
shares of Oi on the Novo Mercado.

The  implementation  of  the  alternative  share  structure  consisted  of  the  corporate  ownership  simplification  transactions  (described 
below), the adoption of new by-laws of the Company, the election of a new board of directors of the Company, and a voluntary share 
exchange through which holders of the Company’s preferred shares were entitled to exchange their preferred shares for the Company’s 
common shares (“voluntary convertion”). 

On  September 1,  2015,  the  Company  and  several  of  its  direct  and  indirect  shareholders  undertook  the  following  transactions,  which 
refer to collectively as the corporate ownership simplification transactions: 

• AG Telecom merged with and into PASA; 

•

•

LF Tel merged with and into EDSP; 

PASA and EDSP merged with and into Bratel Brasil; 

• Valverde merged with and into TmarPart; 

• Venus RJ Participações S.A., Sayed RJ Participações S.A. and PTB2 S.A. merged with and into Bratel Brasil; 

• Bratel Brasil merged with and into TmarPart; and 

•

TmarPart merged with and into the Company. 

In connection with these transactions, all of the shareholders agreements to which the Company was an intervening party and through 
which  the  direct  and  indirect  shareholders  of  TmarPart  had  rights  to  influence  the  Company’s  management  and  operations  were 
terminated. In the merger of TmarPart with and into Oi, the net assets of TmarPart, in the amount of R$122,412 was merged into the 
shareholders’  equity  of  Oi  and  as  a  result  of  the  merger,  TmarPart  ceased  to  exist.  The  merger  of  TmarPart  with  and  into  Oi  also 
resulted  in  the  recognition  its  shareholders’  equity  of  a  tax  benefit  related  to  the  step  up  of  goodwill  tax  basis  in  the  amount  of 
R$982,768 with a corresponding valuation allowance by the same amount derived from the acquisition of equity interest in TmarPart 
recorded by Bratel Brasil, AG Telecom, LF Tel, in accordance with applicable Brazilian law. This tax benefit was recorded directly in 
equity as it was a transaction among and with shareholders’ of Oi. 

In  the  merger  of  TmarPart  with  and  into  Oi,  shareholders  of  TmarPart  received  the  same  number  of  shares  of  Oi  as  were  held  by 
TmarPart  immediately  prior to  the  merger of TmarPart  with and into Oi in proportion  to their holdings  in TmarPart. No  withdrawal 
rights for the holders of shares of Oi were available in connection with the merger of TmarPart with and into Oi. 

At an extraordinary shareholders meeting of the Company held on September 1, 2015, the shareholders (1) adopted amended by-laws of 
the Company that were intended to increase the corporate governance standards applicable to the Company as well as to limit the voting 
rights  of  holders  of  a  large  concentration  of  common  shares,  and  (2) elected  a  new  board  of  directors  with  terms  of  office  until  the 
shareholders’ meeting that approves the financial statements for the year ending December 31, 2017. 

With regard to the Voluntary Conversion, a total of 314,250,655 Oi preferred shares, or 66.84% of total preferred shares ex-treasury, 
were  offered  for  conversion  by  their  holders,  attaining  the  minimum  acceptance  threshold  of  2/3  of  the  holders  of  preferred  shares 
ex-treasury to which the Voluntary Conversion was subject, was reached.

The Company’s Board of Directors ratified the voluntary conversion, accepted the conversion requests filed by the holders of Preferred 
ADSs,  and  approved  the  summon  of  the  Extraordinary  Shareholders’  Meeting  to  reflect  the  new  share  structure,  as  a  result  of  the 
Voluntary Conversion, in the Company’s Bylaws. 

2.       SIGNIFICANT ACCOUNTING POLICIES 

The accounting policies detailed below have been consistently applied in all periods presented in this consolidated financial statements. 

Basis of presentation and going concern assumption 

These consolidated financial statements have been prepared according to United States Generally Accepted Accounting Principles (“US 
GAAP”), which have been prepared under the assumption that the Company will continue as a going concern. 

In August 2014, the FASB issued an accounting standards update which requires management to assess whether there are conditions or 
events, considered in the aggregate, that raise substantial doubt about the entity’s ability to continue as a going concern within one year 
after the financial statements are issued. If substantial doubt exists, additional disclosures are required. This update was effective for the 
Company’s annual periods starting ended December 31, 2016. The Company’s assessment of the ability to continue as a going concern 
is further discussed below. The adoption of the new standard did not have a material impact on the Company’s consolidated financial 
position, results of operations, cash flows or disclosures 

The Company’s current financial situation is a result of several factors. The retention of a large amount of funds in judicial deposits 
related  with  discussions  within  the  regulatory,  labor,  tax,  and  civil  scope,  with  immediate  impact  on  the  liquidity  position  of  Oi 
Companies,  as  well  as  with  the  imposition  of  high  administrative  fines,  particularly  by  ANATEL,  has  contributed  to  the  worsening 
financial situation. 

The change in the standards of consumption of telecommunication services, due to the technological evolution, worsened this scenario 
of financial difficulties even more. With the mass supply of mobile telephony, cable TV and Internet services, the attractiveness of fixed 
telephony services was reduced, which resulted in a decrease in the base of subscribers of Oi Companies in this segment. 

Notwithstanding  the  foregoing,  the  level  of  the  objectives  and  goals  associated  with  the  obligations  of  universalization  of  fixed 
telephony  services  (consolidated  in  the  General  Plan  of  Universalization  Goals,  as  provided  for  in  the  General  Telecommunications 
Law) has remained stable since 1998, the year on which the concession agreements in effect were signed. Therefore, within the context 
of the referred obligations of universalization, Oi Companies finds itself forced to make large investments in certain regions and remote 
locations,  with  low  demographic  density  and  a  low-income  population,  obtaining,  as  compensation,  a  small  financial  return  as 
compared with the regulatory requirement of these investments.

The costs to obtain funds incurred by Oi Companies – taking into account the high interest rates adopted nationwide, as well as the need 
for and cost of foreign exchange protection for funds obtained abroad – are higher than the costs to obtain funds incurred by its direct 
competitors, who are international players, which also contributed to the deterioration of Oi Companies’ financial situation. 

It  is  notable  that  the  Country’s  economic  scenario  has  been  deteriorating  over  the  past  years,  thus  directly  impacting  the  operations 
performed  by  Oi  Companies  and  negatively  affecting  its  liquidity.  Moreover,  the  profile  of  the  market  covered  by  fixed  telephony 
concessionaires competing with the RJ Debtors is more homogeneous and the economic power of their users is materially higher than 
that of those covered by Oi Companies in its area of activity (larger and more heterogeneous than the area of activity of its competitors). 

These events are significant to the financial condition of the company and the combination of these factors prevented compliance with 
several obligations, primarily those assumed by reason of operations involving financial loans and fund raising through the issuance of 
bonds  and  debentures,  representatives  of  the  majority  of  Oi  Companies’s  current  indebtedness,  which  gave  rise  to  the  request  for 
Judicial Reorganization and raise substantial doubt about the Company’s ability to continue as a going concern within one year after the 
date of these financial statements are issued. 

On December 20, 2017 the JRP was approved by the Pre-petition Creditors, which was ratified by the Judicial Reorganization Court on 
January 8, 2018. This ratification decision was issued on February 5, 2018 and, as a result, there was the novation of the pre-petition 
credits. In the course of 2018 and in accordance with ASC 852, the pre-petition balances must be recalculated pursuant to the terms and 
conditions of the Judicial Reorganization Plan, in compliance with the actions needed for its implementation. Judicial Reorganization 
Plan includes: 

• Oi  Companies  will  restructure  and  equalize  its  liabilities  associated  with  Pre-Petition  Credits  and,  at  the  discretion  of  Oi 

Companies, with Post-Petition Credits whose holders wish to be subject to the effects of this Plan. 

•

The company will employ its best efforts to cancel the respective bonds issued and currently existing, in compliance with the 
provisions  of  the  applicable  legislation  to  each  jurisdiction  of  the  RJ  Debtors,  and  may  take  all  applicable  and  required 
measures in any and every applicable jurisdiction, including Brazil, Netherlands, United States of the America and United 
Kingdom, in order to comply with the respective applicable legislations and implement the measures set forth in this Plan. 

• Oi  Companies  will  dispose  of  certain  assets  to  provide  additional  funds.  Oi  Companies  shall  increase  the  capital  in  four 
billion  Reais  (R$  4,000,000,000),  in  order  to  ensure  the  minimum  funds  to  make  the  necessary  capital  expenditures 
investments and modernization of its infrastructure.

capital market. 

• Oi  Companies  will  reorganize  its  corporate  structure,  with  the  purpose  of  obtaining  a  more  efficient  structure  that  is 

appropriate to the implementation of the proposals provided for above and/or any other corporate reorganization. 

• After the Judicial Ratification of the Plan, Oi Companies can immediately withdraw the full amount of the Court Deposits 

that have not been used for payment, as provided for in this Plan. 

•

•

The  Oi  Companies  may  institute  Mediation  /  Conciliation  /  Settlement  procedures  with  its  Creditors  listed  in  the  List  of 
Creditors. 

In order to ensure the execution of the measures provided for in the Plan and considering the various interests involved in the 
Judicial Recovery, the Plan contains transitional corporate governance rules regarding the creation of a Transitional Board of 
Directors and the formation of a New Board of Directors. To ensure the institutional stability of the Oi Companies and the 
implementation of the Plan. 

•

Perform periodic meetings with the FCC according to the above conditions relating to the plan 07/31/18. 

• Conduct periodic meetings with Bondholders to communicate the evolution of the implementation of the Plan. 

Its  historical operating  results  indicate  substantial  doubt  exists  related  to  the  Company’s  ability to  continue  as  a going  concern. It  is 
believed  that  the  actions  discussed  above  are  probable  of  occurring  and  mitigating  the  substantial  doubt  raised  by  the  historical 
operating results and satisfying the estimated liquidity needs 12 months from the issuance of the financial statements. However, it is not 
possible  to  predict,  with  certainty,  the  outcome  of  such  actions  to  generate  liquidity,  including  the  availability  of  additional  debt 
financing,  or  whether  such  actions  would  generate  the  expected  liquidity  as currently  planned.  In  addition,  the  JRP,  contains  certain 
limitations on the Company’s ability to sell assets, which could impact its ability to complete asset sale transactions or to use proceeds 
from  those  transactions  to  fund  its  operations.  Therefore,  the  planned  actions  take  into  account  the  applicable  restrictions  under  the 
reorganization plan. If the Company continues to experience operating losses, and is not able to generate additional liquidity through the 
mechanisms described above or through some combination of other actions, while not expected, it may not be able to access additional 
funds  and  might  need  to  secure  additional  sources  of  funds,  which  may  or  may  not  be  available. Additionally,  a  failure  to  generate 
additional  liquidity  could  negatively  impact  its  access  to  invest  in  capital  expenditures  that  are  important  to  stay  competitive  in  the 
relevant industry. 

Additionally, the Company’s Board of Directors has a reasonable expectation that the Oi Companies will be able to maintain its usual 
activities, hoping that the contracts will remain valid and effective throughout the process of implementing the measures approved in 
the PRJ. Also, an independent appraiser was engaged to issue an economic and financial feasibility valuation report of the Companies 
Undergoing  Reorganization  under  the  JRP,  in  accordance  with  Law  11101,  of  February 9,  2005  that  regulates  the  judicial 
reorganization. The issued economic and financial feasibility report is attached to the judicial reorganization’s records. The continuity 
of the Company as a going concern is ultimately depending on the successful outcome of the judicial reorganization and the realization

of other forecasts of the Oi Companies. To date, as underpinned in the statement attached to the court of the Judicial Reorganization on 
April 10, 2018, by qualified bondholders who have already elected to convert their prepetition claims into Company shares, pursuant to 
Clause  4.3.3.2  of  the  Judicial  Reorganization  Plan,  not  only  the  Companies  Undergoing  Reorganization  but  also  some  of  their  key 
creditors  have  worked  together  to  satisfactorily  comply  with  all  the  deadlines,  legal  requirements,  and  obligations  to  which  they  are 
subject in the context of the judicial reorganization. 

Although,  as  said,  the  Oi  Companies  have  fulfilled  the  obligations  established  in  the Judicial Reorganization proceedings  and  in  the 
approved  PRJ  within  the  established  time  limits,  it  is  emphasized  that  these  conditions  and  circumstances  indicate  the  existence  of 
significant  uncertainty  that  may  affect  the  success  of  the  judicial  reorganization  and  cast  doubts  as  to  the  Oi  Companies  ability  to 
continue as going concern, including the compliance with the resolution and suspensory conditions precedent included in the PRJ. 

Restatement of previously issued financial statements 

The Judicial Reorganization proceedings prompted the Company to engage in a detailed analysis on the completeness and the accuracy 
of  judicial  deposits  and  other  assets  accounting  balances  of  the  entities  involved  in  the  judicial  reorganization.  As  a  result,  it  was 
identified weaknesses in some of operational and financial reporting controls and procedures (Note 1). 

As a result of the detailed analysis, it was determined the need to restate previously issued financial statements and related disclosures 
to correct errors. Accordingly, the Company is restating its consolidated financial statements for the year ended December 31, 2015. 
Restatement  adjustments  attributable  to  fiscal  year  2014  and  previous  are  reflected  as  a  net  adjustment  to  retained  earnings  as  of 
January 1, 2015. 

Errors detected and correct by the Company are as follows: 

(a) Write-off of judicial deposits and increase of provisions for contingencies 

Under  the  Judicial  Reorganization  Proceedings  (i) the  Company  had  the  chance  to  obtain  updated  and  more  detailed  information  on 
judicial bank deposits from creditors that were also the depositaries of judicial bank deposits; (ii) due to the digitalization of a higher 
number of lawsuits the Company was able to use new IT tools to collect updated information from courts of justice’s website related 
with lawsuits with judicial bank deposits; (iii) the determination of the suspension of court claims resulted in a lower number of new 
lawsuits  against  the  Company  and  also  prevented  new  judicial  bank  deposits,  allowing  the  Company  to  focus  in  reconcile  amounts 
deposits recognized in balance sheets and bank statements information. 

With all these information it was identified the opportunity to review some of process and controls related with judicial bank deposits. 
The  Company  implemented  in-house  interdisciplinary  workgroups  and  engaged  outside  independent  experts  to  review  the  controls 
related  with  the  reconciliation  of  accounting  information  of  judicial  bank  deposits’  balances  and  the  correspondent  bank  statements 
obtained and the recalculation of statistical provisions for contingencies.

As  a  result  of  the  above-mentioned  it  was  identified  the  need  to  correct  errors  related  with  (i) the  judicial  bank  deposits  that  were 
recognized in the balance sheet but were withdrawn in previous years by the plaintiff following unfavorable court decisions, of which 
the Company was not aware until the time of this work or because not all elements were available at that time; and (ii) the recalculation 
of  the  statistical  provision  for  civil  and  labor  contingencies  due  to  updated  historical  information  on  unfavorable  court  decisions 
(Note 19). 

As  of  January 1,  2015  it  was  derecognized  judicial  bank  deposits  already  withdrawn  totaling  R$3,133 million  and  increased  the 
provision for contingencies by R$493 million. Net loss for 2015 was increased by R$1,163 million due to the increase on provision for 
contingencies, the write-off of judicial bank deposits and the correction of the correspondent inflation adjustments. 

(b) Recoverable amount of intragroup balances 

During the preparation of the Judicial Reorganization’s list of creditors and due to JRP provision that establishes the rules to recover 
intercompany  claims,  the  Company  performed  additional  procedures  to  obtain  supporting  documentation,  reconciled  intragroup 
balances  and  concluded  for  need  to  recognize  additional  accounts  payable  and  derecognize  accounts  receivable  related  with  those 
intragroup balances. 

As  of  January 1,  2015  the  Company  derecognized  accounts  receivable  totaling  R$167 million  and  increased  accounts  payables  by 
R$172 million. Net loss for 2015 was decreased by R$ 59 million. 

(c) Recoverable amount of tax credits 

The Company concluded that, at December 31, 2015, there was balances related with direct and indirect taxes credits that were expired 
or did not have adequate supporting documentation to claim their refund from tax authorities. 

As  of  January 1,  2015  the  Company  derecognized  balances  of  unrecoverable  tax  credits,  recognized  under  taxes  and  other  assets 
amounting to R$199 million and R$52 million, respectively. 

(d)

Inappropriate estimate of revenue from services rendered and not yet billed to customers 

The Company estimates revenue from services provided and not yet billed to customers using the available information provided by the 
operating  systems.  It  was  identified  that  the  most  recent  operational  information  available  as  of  January 1,  2015  was  not  used  to 
estimate the revenue from services rendered and not yet billed to customers as of that date. 

As of January 1, 2015 there was a reduction in provision for estimated unbilled revenue in the amount R$191 million.

There  is  no  impact  on  operating,  investing,  and  financing  activities  disclosed  in  the  statements  of  cash  flows  for  the  year  ended 
December 31, 2015. 

Use of estimates 

In preparing the financial statements in conformity with U.S. Generally Accepted Accounting Principles, the Company’s management 
uses estimates and assumptions based on historical experience and other factors, including expected future events, which are considered 
reasonable and relevant. The use of estimates and assumptions frequently requires judgments related to matters that are uncertain with 
respect to the outcomes of transactions and the amount of assets and liabilities. Actual results of operations and the financial position 
may differ from these estimates. Significant items subject to such estimates and assumptions include the useful lives of fixed  assets, 
allowances  for  doubtful  accounts,  the  valuation  of  derivatives,  the  valuation  of  available-for-sale  investment,  deferred  tax  assets, 
valuation of fixed assets, pension plan, income tax uncertainties and contingencies. 

The estimate of the expected amount of the allowed claim is a significant estimate. As the estimation process is inherently uncertain, 
future  actions  and  decisions  by  the  Judicial  Reorganization  Court  may  differ  significantly  from  its  own  estimate,  potentially  having 
material future effects on its financial statements. Furthermore, these liabilities are reported as the amounts expected to be allowed by 
the Judicial Reorganization Court, even if they may be settled for lesser amounts. There may be significant variation between the settled 
amount and the expected amount of the allowed claim.

Consolidated Financial Statements 

The  accompanying  consolidated  financial  statements  include  the  accounts  of  the  Company  and  its  subsidiaries.  All  significant 
intercompany balances and transactions have been eliminated in consolidation. The Company accounts for investments over which it 
has significant influence but not a controlling financial interest using the equity method of accounting. 

The assets and liabilities related to the operations in Africa are stated in a single line item of the balance sheet as held-for-sale assets as 
a result of Management’s expectation and decision to hold these assets and liabilities for sale. In the statement of operations, however, 
costs/expenses  and  revenue/gains  are  stated  under  the  full  consolidation  method  because  these  assets  do  not  meet  the  criteria  to  be 
classified as ‘discontinued operation. 

New Accounting Standards 

In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers (Topic 606)” (“ASU 2014-09”), and has since 
modified the standard with several ASUs. The standard is effective for the Company, and was adopted on January 1, 2018. 

The standard requires entities to recognize revenue through the application of a five-step model, which includes: identification of the 
contract; identification of the performance obligations; determination of the transaction price; allocation of the transaction price to the 
performance obligations; and recognition of revenue as the entity satisfies the performance obligations. 

The  guidance  permits  two  methods  of  adoption,  the  full  retrospective  method  applying  the  standard  to  each  prior  reporting  period 
presented, or the modified retrospective method with a cumulative effect  of initially applying the guidance recognized at the date of 
initial application. The standard also allows entities to apply certain practical expedients at their discretion. The Company will adopt the 
standard  using  the  modified  retrospective  method  with  a  cumulative  catch  up  adjustment  and  will  provide  additional  disclosures 
comparing  results  to  previous  GAAP  in  the  2018 consolidated  financial  statements.  The  Company  plans  to  apply  the  new  revenue 
standard only to contracts not completed as of the date of initial application, referred to as open contracts. 

The most significant judgments and impacts upon adoption of the standard include the following items: Sales of handheld devices at a 
discount—The Company offers its  customers, who have  acquired  a  given  service package  or  entered  into certain  mobility  contracts, 
handheld devices at a discount. Since the equipment (cellphone) is not a key condition for the provision of the service and there is no 
customization  by  the  Company  to  offer  the  service  using  a  given  device,  the  Company  considers  such  sale  a  separate  performance 
obligation.  The  discount  should  be  allocated  to  the  performance  obligations  arising  on  the  sale  of  plans  and  in  a  mobility  contract 
(corporate customers) and the revenue from the sale of handheld devices should increase due to the recognition of the revenue from the 
sale of

cellphones at the time the control over the good is transferred to the customer, while the service revenue should be reduced throughout 
the transfer of the promised service. The total revenue earned throughout the entire service agreement will not change and there will be 
no change either in the revenue process from customers and the Company’s cash flows. 

Revenue from registration/service installation fees—The registration/installation fee collected from customers at the time a contract is 
nonrefundable and refers to the activity the Company is required to undertake when entering into a contract or a comparable activity 
required to fulfill such contract, while such activity does not entail the transfer of a good or the service promised to the customer. The 
fee is an advance payment for future goods or services and, therefore, should be recognized as revenue when such goods or services are 
supplied. Considering that such fees are a separate performance obligation, revenue must be recognized together with the revenue of 
said service provision, i.e., it should be deferred and recognized in profit or loss throughout the contract period. As a cumulative effect 
adjustment to equity net of taxes, it is expected to record deferred revenue of R$138 million upon adoption on January 1, 2018. 

Recognition of costs incurred on the performance of a contract—The Company must recognize as an asset the incremental costs with 
commission incurred to obtain a contract with a customer that are expected to be recovered, and must recognize an impairment loss in 
profit or loss as the carrying amount of the recognized asset exceed the remaining amount of the consideration the Company expects to 
receive in exchange for the goods and services to which the asset refers. The Company must recognize in assets certain costs that are 
currently recognized directly in profit or loss and recognize them on a systematic basis, consistent with the transfer of the goods and 
services to which the asset refers to the customer. Incremental contract acquisition costs paid on open contracts of approximately R$793 
million are expected to be capitalized and subsequently amortized upon adoption on January 1, 2018 as a cumulative effect adjustment 
to  equity, which consists  primarily of commissions  paid  to acquire  branded postpaid service  contracts.  Contract costs capitalized for 
new contracts will accumulate during 2018 as deferred assets. As a result, it is expected there will be a net benefit to operating income 
during  2018.  As  capitalized  costs  amortize  into  expense  over  time  the  accretive  benefit  to  operating  income  anticipated  in  2018  is 
expected to moderate in 2019 and become insignificant in 2020 as the timing benefits of deferring these costs dissipate. 

The  Company  is  in  the  process  of  implementing  new  revenue  accounting  systems,  processes  and  internal  controls  over  revenue 
recognition to assist its in the application of the new standard. The cumulative effect of initially applying the new revenue standard on 
January 1, 2018 is estimated to be a decrease to Accumulated deficit of approximately R$ 655 million. 

Business  Combinations—In  September  2015,  the  FASB  issued  ASU  No. 2015-16,  “Business  Combinations  –  Simplifying  the 
Accounting for Measurement- Period Adjustments” (ASU 2015-16), which results in the ability to recognize, in current period earnings, 
any changes in provisional amounts during the measurement period after the closing of an acquisition, instead of restating prior periods 
for these changes. This standard had no impact on the consolidated balance sheet, or consolidated operating results and cash flows for 
the years ended.

Leases—In  February  2016,  the  FASB  issued  ASU  2016-02  which  supersedes  FASB  ASC  Topic  840,  Leases,  and  makes  other 
conforming  amendments  to  U.S.  GAAP.  ASU  2016-02  requires,  among  other  changes  to  the  lease  accounting  guidance,  lessees  to 
recognize most leases on-balance sheet via a right of use asset and lease liability, and additional qualitative and quantitative disclosures. 
ASU  2016-02  is  effective  for  the  Company  for  annual  periods  in  fiscal  years  beginning  after  December 15,  2018,  permits  early 
adoption,  and  mandates  a  modified  retrospective  transition  method.  The  Company  is  required  to  adopt  ASU  2016-02  on  January 1, 
2019, but is evaluating whether to early adopt the new standard. The Company will adopt the new standard on January 1, 2019, and is 
currently evaluating the effect that ASU 2016-02 will have on its consolidated financial statements. 

Recognition and Measurement of Financial Assets and Financial Liabilities—In January 2016, the FASB issued ASU 2016-01 which 
makes targeted improvements to the accounting for, and presentation and disclosure of, financial instruments, except those accounts for 
under the equity method or those that result in consolidation. ASU 2016-01 requires that most equity investments be measured at fair 
value, with subsequent changes in fair value recognized in net income. ASU 2016-01 does not affect the accounting for investments that 
would otherwise be consolidated or accounted for under the equity method. The new standard also impacts financial liabilities under the 
fair  value  option  and  the  presentation  and  disclosure  requirements  for  financial  instruments.  The  provisions  of  ASU  2016-01  are 
effective  for  the  Company  for  annual  periods  in  fiscal  years  beginning  after  December 15,  2018.  The  Company  will  adopt  the  new 
standard on January 1, 2019, and is currently evaluating the effect that ASU 2016-01 will have on its consolidated financial statements. 

Measurement of Credit Losses on Financial Instruments—In June 2016, the FASB issued ASU 2016-13 which requires a financial asset 
(or  a  group  of  financial  assets)  measured  at  amortized  cost  basis  to  be  presented  at  the  net  amount  expected  to  be  collected.  The 
measurement  of  expected  credit  losses  is  based  on  relevant  information  about  past  events,  including  historical  experience,  current 
conditions  and  reasonable  and  supportable  forecasts  that  affect  the  collectability  of  the  reported  amount.  The  standard  will  become 
effective for the Company beginning January 1, 2020 and will require a cumulative-effect adjustment to Accumulated deficit as of the 
beginning of the first reporting period in which the guidance is effective (that is, a modified-retrospective approach). Early adoption is 
permitted as of January 1, 2019. The Company is currently evaluating the impact this guidance will have on the consolidated financial 
statements and the timing of adoption. 

Classification of Certain Cash Receipts and Cash Payments in the Cash Flow—In August 2016, the FASB issued ASU 2016-15, which 
provides  guidance  on  how  certain  cash  receipts  and  payments  are  presented  and  classified  in  the  statement  of  cash  flows,  including 
beneficial interests in securitization, which would impact the presentation of the deferred purchase price from sales of receivables. The 
standard  is  intended  to  reduce  current  diversity  in  practice.  The  standard  will  become  effective  beginning  January 1,  2018  and  will 
require  a  retrospective  approach.  Early  adoption  is  permitted,  including  adoption  in  an  interim  period.  The  Company  is  currently 
evaluating the standard, but expect that it will not have a material impact on the consolidated financial statements. 

Accounting  for  Income  Taxes:  Intra-Entity  Transfers  of  Assets  Other  Than  Inventory—In  October  2016,  the  FASB  issued  ASU 
2016-16 which requires that the income tax impact of intra-entity sales and transfers of property, except for inventory, be recognized 
when the transfer occurs. The standard will

become  effective  beginning  January 1,  2018  and  will  require  any  deferred  taxes  not  yet  recognized  on  intra-entity  transfers  to  be 
recorded  to  retained  earnings  under  a  modified  retrospective  approach.  Early  adoption  is  permitted.  The  Company  is  currently 
evaluating the standard, but expects that it will not have a material impact on the consolidated financial statements. 

Classification  of  Restricted  Cash  in  the  cash  flow—In  November  2016,  the  FASB  issued  ASU  2016-18  which  requires  entities  to 
include in their cash and cash-equivalent balances in the statement of cash flows those amounts that are deemed to be restricted cash 
and restricted cash equivalents. The ASU does not  define the terms “restricted cash” and “restricted cash equivalents.”  The standard 
will  be  effective  beginning  January 1,  2018  and  will  require  a  retrospective  approach.  Early  adoption  is  permitted.  The  Company  is 
currently evaluating the standard, but expects that it will not have a material impact on the consolidated financial statements. 

Simplifying the Test for Goodwill Impairment—In January 2017, the FASB issued ASU 2017-04 which eliminates the requirement to 
measure the implied fair value of goodwill by assigning the fair value of a reporting unit to all assets and liabilities within that unit (“the 
Step 2 test”) from the goodwill impairment test. Instead, if the carrying amount of a reporting unit exceeds its fair value, an impairment 
loss is recognized in an amount equal to that excess, limited by the amount of goodwill in that reporting unit. The standard will become 
effective  beginning  January 1,  2020  and  must  be  applied  to  any  annual  or  interim  goodwill  impairment  assessments  after  that  date. 
Early adoption is permitted. The Company is currently evaluating the standard, but expects that it will not have a material impact on the 
consolidated financial statements. 

Functional and presentation currency 

The  Company  and  its  subsidiaries  operate  primarily  as  telecommunications  operators  in  Brazil,  Africa,  and  Asia,  and  engage  in 
activities  typical  of  this  industry.  The  items  included  in  the  financial  statements  of  each  group  company  are  measured  using  the 
currency of the main economic environment of the respective company’s operations (“functional currency”). The consolidated financial 
statements are presented in Brazilian Reais (R$), which is the Company’s functional and presentation currency. 

Transactions and balances 

Foreign  currency-denominated  transactions  are  translated  into  the  functional  currency  using  the  exchange  rates  prevailing  on  the 
transaction dates. Foreign exchange gains and losses arising on the settlement of the transaction and the translation at the exchange rates 
prevailing at year end, related foreign currency-denominated monetary assets and liabilities are recognized in the statement of profit or 
loss, except when qualified as hedge accounting and, therefore, deferred in equity as cash flow hedges.

Group companies with a different functional currency 

The profit or  loss  and the financial position of all  Group  entities,  none of  which  uses  a currency  from a hyperinflationary economy, 
whose functional currency is different from the presentation currency are translated into the presentation currency as follows: 

•

•

•

•

assets and liabilities are translated at the prevailing rate at the end of the reporting period; 

revenue and expenses disclosed in the statement of profit or loss are translated using the average exchange rate; 

all  the  resulting  foreign  exchange  differences  are  recognized  as  a  separate  component  of  equity  in  other  comprehensive 
income; and 

goodwill and fair value adjustments, arising from the acquisition of a foreign entity are treated as assets and liabilities of the 
foreign entity and translated at the closing exchange rate.

The  presentation  of information  relating  to  operating  segments  is  consistent  with  the  internal  reports  provided  to  the chief  operating 
decision  maker  of  the  Company,  defined  by  the  Company  as  the  Board  of  Executive  Officers  (Comitê  de  Gestão).  The  results  of 
segment  operations  are  regularly  reviewed  in  order  to  make  decisions  about  the  allocation  of  resources  to  assess  operational 
performance and for strategic decision-making. 

Business combinations 

The Company uses the acquisition method to account for business combinations. The consideration transferred for the acquisition of a 
subsidiary  is  the  fair  value  of  the  assets  transferred,  the  liabilities  incurred,  and  the  equity  instruments  issued.  The  consideration 
transferred  includes  the  fair  value  of  assets  and  liabilities  resulting  from  a  contingent  consideration  contract,  where  applicable.  The 
identifiable assets acquired and the liabilities and contingent liabilities assumed in a business combination are initially measured at their 
fair  values  at  the  date  of  acquisition.  The  Company  depreciates  amounts  recognized  according  to  the  useful  lives  of  the  underlying 
assets,  and  tests  such  assets  to  determine  any  asset  impairment  losses  when  there  is  evidence  of  impairment.  The  Company  tests 
goodwill for impairment on an annual basis. 

Investment Securities 

Investment  securities  at  December 31,  2017  and  2016  consist  of  short-term  and  long-term  investments  classified  as  trading  and  an 
investment  at  Unitel  classified  as  available-for-sale.  Trading  and  available-for-sale  securities  are  recorded  at  fair  value.  Unrealized 
holding gains and losses on trading securities are included in earnings. Unrealized holding gains and losses, net of the related tax effect, 
on  available-for-sale  securities  are  excluded  from  earnings  and  are  reported  as  a  separate  component  of  accumulated  other 
comprehensive income until realized. 

A decline in the market value of any available-for-sale below cost that is deemed to be other-than-temporary results in an impairment to 
reduce  the  carrying  amount  to  fair  value.  To  determine  whether  an  impairment  is  other-than-temporary,  the  Company  considers  all 
available information relevant to the collectability of the security, including past events, current conditions, and reasonable and

supportable forecasts when developing estimate of cash flows expected to be collected. Evidence considered in this assessment includes 
the  reasons  for  the  impairment,  the  severity  and  duration  of  the  impairment,  changes  in  value  subsequent  to  year-end,  forecasted 
performance of the investee, and the general market condition in the geographic area or industry the investee operates in. 

Cash and cash equivalents 

This  caption  includes  cash  and  cash  fund,  banks,  and  highly  liquid  short-term  investments  (usually  maturing  within  less  than  three 
months), immediately convertible into a known cash amount, and subject to an immaterial risk of change in value, which are stated at 
fair  value  at  the  end  of  the  reporting  period  and  which  do  not  exceed  their  market  value,  and  whose  classification  is  determined  as 
shown below. 

Cash investments 

Cash investments are classified according to their purpose as: (i) held for trading; (ii) held to maturity; and (iii) available for sale. 

Held-for-trading investments are measured at fair value and their effects are recognized in profit or loss. Held-to-maturity short-term 
investments are measured at the cost of acquisition plus interest earned, less allowance for impairment losses, where applicable, and 
their effects are recognized in profit or loss. Available-for-sale investments are measured at fair value and their effects are recognized in 
valuation adjustments to equity, when applicable. 

Accounts receivable 

Accounts receivable from telecommunications services provided are stated at the tariff or service amount on the date they are provided 
and do not differ from their fair values. 

These  receivables  also  include  receivables  from  services  provided  and  not  billed  by  the  end  of  the  reporting  period  and  receivables 
related  to handset,  SIM  cards,  and  accessories.  The  allowance  for  doubtful accounts estimate  is  recognized  in  an amount  considered 
sufficient  to  cover  possible  losses  on  the  realization  of  these  receivables.  The  allowance  for  doubtful  accounts  estimate  is  prepared 
based on historic default rates. 

The  allowance  for  doubtful  accounts  is  set  up  to  recognize  probable  losses  on  accounts  receivable  taking  into  account  the  measures 
implemented to restrict the provision of services to and collect late payments from customers. 

There  are  cases  of  agreements  with  certain  customers  to  collect  past-due  receivables,  including  agreements  that  allow  customers  to 
settle  their  debts  in  installments.  The  actual  amounts  not  received  may  be  different  from  the  allowance  recognized,  and  additional 
accruals might be required.

Non-current assets held for sale and discontinued operations 

Disposals that represent a strategic shift that should have or will have a major effect on the Company’s operations and financial results 
qualify as discontinued operations. The results of discontinued operations are reported in discontinued operations in the consolidated 
statements of income for current and prior periods commencing in the period in which the business meets the criteria of a discontinued 
operation, and include any gain or loss recognized on closing or adjustment of the carrying amount to fair value less cost to sell. 

Property, plant and equipment 

Property  and equipment  consists  of  transmission equipment, trunking and  switching stations,  metallic and fiber-optic cable networks 
and  lines,  underground  ducts,  posts  and  towers,  data  communication  equipment,  network  systems  and  infrastructure  and  motor-
generator groups. 

Property,  plant  and  equipment  is  stated  at  cost  of  purchase  or  construction,  less  accumulated  depreciation.  Historical  costs  include 
expenses directly attributable to the acquisition of assets. They also include certain costs for facilities, when it is probable that the future 
economic  benefits  related  to  such  costs  will  flow  to  the  Company.  The  borrowings  and  financing  costs  directly  attributable  to  the 
purchase, construction or production of a qualifying asset are capitalized in the initial cost of such asset. Qualifying assets are those that 
necessarily require a significant time to be ready for use. 

Costs of major replacements and improvements are capitalized. Repair and maintenance expenditures which do not enhance or extend 
the asset’s useful life are charged to operating expenses as incurred. 

Depreciation  is  calculated  on  a  straight-line  basis,  based  on  the  estimated  useful  lives  of  the  assets.  The  useful  lives  are  reviewed 
annually by the Company. 

Intangible assets 

Acquired  intangible  assets  with  finite  useful  lives  are  recognized  at  cost,  less  amortization  and  accumulated  impairment  losses. 
Amortization  is  recognized  on  a  straight-line  basis  over  the  asset’s  estimated  useful  life.  The  estimated  useful  life  and  method  of 
amortization are reviewed at the end of each annual reporting period, and the effect of any changes in estimates is accounted for on a 
prospective basis. Intangible assets with indefinite useful lives are carried at cost less accumulated impairment losses. 

Software licenses purchased are capitalized based on the costs incurred to purchase the software and make it ready for use. Software 
maintenance costs are expensed as incurred. 

Regulatory licenses acquired in a business combination are amortized over the STFC concession period. The regulatory licenses for the 
operation of the mobile telephony services are recognized at cost of acquisition and amortized over the effective period of each licenses.

Long-lived assets 

Long-lived  assets  include  assets  that  do  not  have  indefinite  lives,  such  as  property,  plant,  and  equipment,  and  purchased  intangible 
assets  subject  to  amortization.  They  are  reviewed  for  impairment  whenever  events  or  changes  in  circumstances  indicate  that  the 
carrying amount of an asset may not be recoverable. If any indicators of impairment are present, it is performed a test for recoverability. 
The carrying value of a long-lived asset or asset group is not recoverable if it exceeds the sum of the undiscounted cash flows expected 
to be generated from the use and eventual disposition of the asset or asset group. If the undiscounted cash flows do not exceed the asset 
or asset group’s carrying amount, then an impairment loss is recorded, measured as the amount by which the carrying amount of a long-
lived asset or asset group exceeds its fair value. 

Provision for contingencies 

Liabilities for loss contingencies arising from claims, assessment, litigation, fines and penalties are recorded when it is probable that the 
liability  has  been  incurred  and  the  amount  can  be  reasonably  estimated,  based  on  opinion  of  the  management  and  its  in-house  and 
outside legal counsel, and the amounts are recognized based on the cost of the expected outcome of ongoing lawsuits. 

Pension and other postretirement plans 

The Company and its subsidiaries have defined benefit and defined contribution plans. The Company also sponsors a defined benefit 
health care plan for retirees and employees. 

Private  pension  plans  and  other  postretirement  benefits  sponsored  by  the  Company  and  its  subsidiaries  for  the  benefit  of  their 
employees  are  managed  by  two  foundations.  Contributions  are  determined  based  on  actuarial  calculations,  when  applicable,  and 
charged to profit or loss on the accrual basis 

In the defined contribution plan, the sponsor makes fixed contributions to a fund managed by a separate entity. The contributions are 
recognized  as  employee  benefit  expenses  as  incurred.  The  sponsor  does  not  have  the  legal  or  constructive  obligation  of  making 
additional contributions, in the event the fund lacks sufficient assets to pay all employees the benefits related to the services provided in 
the current year and prior years. 

For  the  defined  benefit  plans,  the  Company  records  annual  amounts  relating  to  its  pension  and  postretirement  plans  based  on 
calculations  that  incorporate  various  actuarial  and  other  assumptions,  including  discount  rates,  mortality,  assumed  rates  of  return, 
compensation increases, turnover rates and healthcare cost trend rates. The Company reviews its assumptions on an annual basis and 
makes modifications to the assumptions based on current rates and trends when it is appropriate to do so. The effect of modifications to 
those assumptions is recorded in accumulated other comprehensive income and amortized to net periodic cost over future periods using 
the  corridor  method.  The  Company  believes  that  the  assumptions  utilized  in  recording  its  obligations  under  its  plans  are  reasonable 
based on its experience and market conditions.

The Company recognizes the over or under-funded status of a defined benefit postretirement plan as an asset or liability in its balance 
sheet and to recognizes changes in that funded status in the year in which the changes occur through other comprehensive income. 

The Company is not required to record actuarial calculations for multi-employer pension plans such as the PBS-A and contributions to 
such plans are recorded on an accrual basis. Refunds from these plans are recorded only upon the cash receipt. 

Revenue recognition 

Revenues correspond basically to the amount of the payments received or receivable from sales of services in the regular course of the 
Company’s and its subsidiaries’ activities. 

Service  revenue  is  recognized  when  services  are  provided.  Local  and  long  distance  calls  are  charged  based  on  time  measurement 
according to the legislation in effect. The services charged based on monthly fixed amounts are calculated and recorded on a straight-
line basis. Prepaid services are recognized as unearned revenues and recognized in revenue as services are used by customers. 

Revenue from sales of handsets and accessories is recognized when these items are delivered and accepted by the customers. Discounts 
on  services  provided  and  sales  of  cell  phones  and  accessories  are  taken  into  consideration  in  the  recognition  of  the  related  revenue. 
Revenues involving transactions with multiple elements are identified in relation to each one of their components and the recognition 
criteria are applied on an individual basis. Revenue is not recognized when there is significant uncertainty as to its realization. 

Financial income and expenses 

Financial income is recognized on an accrual basis and comprises interest on receivables settled after the due date, gains on short-term 
investments  and  gains  on  derivative  instruments.  Financial  expenses  represent  interest  effectively  incurred  and  other  charges  on 
borrowings,  financing,  derivative  contracts,  and  other  financial  transactions.  They  also  include  banking  fees  and  costs,  financial 
intermediation costs on the collection of trade receivables, and other financial transactions. 

Income taxes 

Income taxes are recorded under the asset and liability method. Deferred taxes assets and liabilities are recognized for the future tax 
consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their tax 
basis and for tax loss carryforwards. Deferred tax assets are reduced by a valuation allowance to the amount more likely than not to be 
realized. The Company recognizes the effect of income tax positions only if those positions are more likely than not of being sustained. 
Recognized income tax positions are measured at the largest amount that is greater than 50 percent likely of being realized. Changes in 
recognition or measurement are reflected in the period in which the change in judgment occurs.

The  company  and  its  subsidiaries  file  income  tax  returns  in  all  jurisdictions  in  which  they  do  business  (Brazil  is  the  only  major  tax 
jurisdiction). In Brazil, income tax returns are subject to review and adjustment by the tax authorities during a period of five calendar 
years. Positions challenged by the taxing authorities may be settled or appealed by the company. In Brazil all audit periods prior to 2012 
are closed for federal examination purposes. 

As of December 31, 2017 the company has no unrecognized tax benefits, nor any interest and penalties thereon. Interest and penalties 
on an underpayment of income taxes are recognized as part of interest expense and other expenses, respectively.

Accordingly, for the closing of 2017: 

(i)

The balances of accounts receivables if the fourth quarter of 2017 and trade payables have short terms and, therefore, they are not 
adjusted to fair value. 

(ii) The licenses  and concessions  payable, the tax refinancing program,  and other obligations  (payable  for the acquisition of equity 

interest) are stated at the amounts that these obligations are expected to be discharged. 

Fair value of financial instruments 

The  Company  and  its  subsidiaries  have  measured  their  financial  assets  and  financial  liabilities  at  fair  value  using  available  market 
inputs and valuation techniques appropriate for each situation. The interpretation of market inputs for the selection of such techniques 
requires  considerable  judgment  and  the  preparation  of  estimates  to  obtain  an  amount  considered  appropriate  for  each  situation. 
Accordingly, the estimates presented may not necessarily be indicative of the amounts that could be obtained in an active market. The 
use of different assumptions for the calculation of the fair value may have a material impact on the amounts. 

(a)

Derivative financial instruments 

The  method  used  for  calculating  the  fair  value  of  derivative  financial  instruments  was  the  future  cash  flows  associated  to  each 
instrument contracted, discounted at market rates. 

The Company conducted derivative transactions to manage certain market risks, mainly the interest rate risk and foreign exchange risk. 
As a result of the Company’s Board of Directors’ decision, and because of the expected debt restructuring, these derivative contracts 
were cancelled and their balances reversed throughout the second and third quarters of 2016. As at December 31, 2017 the Company no 
longer held derivative contracts. 

(b)

Non-derivative financial instruments measured at fair value 

The fair value of securities traded in active markets is equivalent to the amount of the last closing quotation available at the end of the 
reporting period, multiplied by the number of outstanding securities. 

For the remaining contracts, the Company carries out an analysis comparing the current contractual terms and conditions with the terms 
and conditions effective for the contract when they were originated. When terms and conditions are dissimilar, fair value is calculated 
by discounting future cash flows at the market rates prevailing at the end of the period, and when similar, fair value is similar to the 
carrying amount on the reporting date.

Refers to the fair value of the financial investment in Unitel and CVT, classified as an available-for-sale financial asset and recoverable 
amount  of  dividends  receivable  from  Unitel.  The  fair  value  of  the  investments  is  estimated  based  on  the  internal  valuation  made, 
including cash flows forecasts for a five-year period, the choice of a growth rate to extrapolate the cash flows projections, and definition 
of appropriate discount rates and foreign exchange rates consistent with the reality of each country where the businesses are located. In 
addition  to  the  financial  and  business  assumptions  referred  to  above,  the  Company  also  takes  into  consideration  the  fair  value 
measurement  of  cash  investments,  qualitative  assumptions,  including  the  impacts  of  developments  in  the  lawsuits  filed  against  third 
parties,  and  the  opinion  of  the  legal  counsel  on  the  outcome  of  these  lawsuits.  With  regard  to  the  impairment  test  of  dividends,  the 
Company uses financial assumptions on the discount rate in time and the foreign exchange rate, and uses qualitative assumptions based 
on the opinion of the legal counsel on the outcome of filed against Unitel for the nonpayment of dividends and interest. 

The Company monitors and periodically updates the key assumptions and critical estimates used to calculate fair value. 

(c)

Fair value measurement hierarchy 

Fair value is the price for which an asset could be exchanged, or a liability settled, between knowledgeable, willing parties, in an arm’s 
length transaction on measurement date. The fair value is be based on the assumptions that market participants consider in pricing an 
asset or a liability, and in the establishment a hierarchy that prioritizes the information used to build such assumptions. The fair value 
measurement hierarchy attaches more importance to available market inputs (i.e., observable data) and a less weight to inputs based on 
data without transparency (i.e., unobservable data). Additionally, the Company considers all nonperformance risk aspects, including the 
entity’s credit, when measuring the fair value of a liability. 

The  classification  of  an  instrument  in  the  fair  value  measurement  hierarchy  is  based  on  the  lowest  level  of  input  significant  for  its 
measurement. The description of three-level hierarchy is presented below: 

Level 1—inputs consist of prices quoted (unadjusted) in active markets for identical assets or liabilities to which the entity has access 
on measurement date; 

Level 2—inputs are different from prices quoted in active markets used in Level 1 and consist of directly or indirectly observable inputs 
for the asset or liability. Level 2 inputs include quoted prices for similar assets or liabilities in active markets, quoted prices for identical 
assets or liabilities in markets that are not active; or inputs that are observable for the asset or liability or that can support the observed 
market inputs by correlation or otherwise for substantially the entire asset or liability. 

Level  3—inputs  used  to  measure  an  asset  or  liability  are  not  based  on  observable  market  variables.  These  inputs  represent 
management’s best estimates and are generally measured using pricing models, discounted cash flows, or similar methodologies that 
require significant judgment or estimate.

There  were  no  transfers  between  levels  in  the  years  ended  December 31,  2017  and  2016.  In  the  second  and  third  quarters  of  2016, 
because  of  the  expected  debt  restructuring,  the  Company  cancelled  all  its  derivative  contracts.  The  remaining  balance  refers  to  an 
agreement  entered  into  with  a  financial  institution  that  is  now  included  in  the  list  of  Company  creditors  and  it  is  under  the  Judicial 
Reorganization and should not change in the future as a result of any development in the foreign exchange and interest areas. 

3.2. Measurement of financial assets and financial liabilities at amortized cost 

The fair value of the financial instruments mentioned below is substantially close to the carrying amounts due to the following reasons: 

• Accounts receivables: short-term maturity of bills. 

•

Trade payables, dividends and interests on capital: all obligations are due to be settled in the short term. 

• Borrowings and financing: all transactions are adjusted for inflation based on contractual indices. 

•

Licenses  and  concessions  payable,  tax  refinancing  program  and  other  payables  (payable  for  the  acquisition  of  equity 
interests): all payables are adjusted for inflation based on the contractual indices. 

3.3.

Financial risk management 

The  Company’s  and  its  subsidiaries’  activities  expose  them  to  several  financial  risks,  such  as:  market  risk  (including  currency 
fluctuation risk, interest rate risk on fair value, interest rate risk on cash flows, and price risk), credit risk, and liquidity risk. According 
to  their  nature,  financial  instruments  may  involve  known  or  unknown  risks,  and  it  is  important  to  assess  to  the  best  judgment  the 
potential  of  these  risks.  The  Company  and  its  subsidiaries  may  use  derivative  financial  instruments  to  mitigate  certain  exposures  to 
these risks.

The Company’s treasury officer, in accordance with the policies approved by the Board of Directors, carries out risk management. 

The Hedging and Cash Investments Policies, approved by the Board of Directors, document the management of exposures to market 
risk factors generated by the financial transactions of the Oi Group companies. 

As decided by the Board of Directors, in light of the expected debt restructuring and the filing of the Company’s judicial reorganization, 
the Company’s derivatives portfolio was reversed throughout the second quarter until it was fully settled in July of 2016.

Financial assets 

The  Company  is  not  exposed  to  any  material  foreign  exchange  risk  involving  foreign  currency-denominated  financial  assets  at 
December 31, 2017, except with regard to the assets held for sale, for which there was no currency hedging transactions. 

Net investment in foreign subsidiaries 

The risks related to the Company’s investments in foreign currency arise mainly from the investments in the subsidiaries in Africa. The 
Company does not have any contracted instrument to hedge against the risk associated to the net investments in foreign companies.

Foreign exchange risk sensitivity analysis 

At December 31, 2017, management estimated the depreciation scenarios of the Brazilian real in relation to other currencies, at the end 
of the reporting period. It is worth noting, however, that in light of the filing of the judicial reorganization request on June 20, 2016—as 
referred  to  in  Note  1—the  Company’s  foreign  currency-denominated  financial  liabilities  are  part  of  the  list  of  payables  subject  to 
renegotiation.  Contingent  to  the  successful  implementation  of  said  negotiation,  the  scenarios  described  below  should  not  represent  a 
cash  outflow  risk.  In  the  period  from  the  filing  and  approval  and  ratification  of  the  judicial  reorganization  plan  by  the  creditors  the 
payment of interest and repayment of principal of the Company’s borrowings and financing are suspended. 

For  purposes  of this  Instruction,  however,  the rates  used  for  the  probable  scenario were  the  rates  prevailing at  the  end  of  December 
2017.  The  probable  rates  were  then  depreciated  by  25%  and  50%  and  used  as  benchmark  for  the  possible  and  remote  scenarios, 
respectively.

Cash equivalents and short-term  investments in local currency are substantially maintained in  financial investment funds exclusively 
managed for the Company and its subsidiaries, and investments in private securities issued by prime financial institutions. 

The interest rate risk linked to these assets arises from the possibility of decreases in these rates and consequent decrease in the return 
on these assets. 

These assets are presented in the balance sheet as follows:

The  concentration  of  credit  risk  associated  to  trade  receivables  is  immaterial  due  to  the  diversification  of  the  portfolio.  Doubtful 
receivables are adequately covered by an allowance for doubtful accounts. 

Transactions  with  financial  institutions  (cash  investments  and  borrowings  and  financing)  are  made  with  prime  entities,  avoiding  the 
concentration risk. The credit risk of financial investments is assessed  by setting  caps for investment in the counterparts, taking into 
consideration  the  ratings  released  by  the  main  international  risk  rating  agencies  for  each  one  of  such  counterparts.  At  December 31, 
2017,  2016  and  2015,  approximately  95.8%,  95.8%  and  99.2%  of  the  consolidated  short  term  investments  were  made  with 
counterparties with an AAA, AA, A, and sovereign risk rating. 

The Company has credit risks related to dividends receivable associated to the investment in Unitel (Note 25).

3.4.3. Liquidity risk 

The liquidity risk also arises from the possibility of the Company being unable to discharge its liabilities on maturity dates and obtain 
cash due to market liquidity restrictions. Management uses its resources mainly to fund capital expenditures incurred on the expansion 
and upgrading of the network, invest in new businesses. 

The Company’s management monitors the continual forecasts of the liquidity requirements to ensure that the company has sufficient 
cash to meet its operating needs and fund capital expenditure to modernize and expand its network. 

In light of the current judicial reorganization  scenario, as referred  to  in  Note 1,  the  Company’s obligations related to the contractual 
maturities  of  financial  liabilities,  including  the  payments  of  interest  in  borrowings,  financing  and  debentures,  were  negotiated  with 
creditors and will be repaid under the terms of the JRP.

to  Africa  (Note  25)  which  is  being  reported  as  held  for  sale,  in  amounting  R$46,534  and  R$225,512,  respectively.  As  at 
December 31,  2015,  the  Company  conducted  the  annual  impairment  test  and  recognized  a  loss  on  goodwill  amounting  to 
R$501,465  related  to  goodwill  and  trademarks  for  the  Telecommunication  services  in  Brazil  due  to  a  significant  change  in  the 
macroeconomic conditions in Brazil and R$89,176 related to Africa which is being reported as held for sale. The fair value of the 
reporting unit was estimated using the expected present value of future cash flows. 
In 2017 refers to the effects of non-recurring expenses related to unrecoverable tax, write-off of other assets and other expenses of 
R$1,188 million (R$227 million in 2016) due to reconcile the accounting balances as part of the process of JRP. In 2015 primarily 
include the reversal of a civil contingency amounting to R$325,709 arising from the revision of the calculation methodology and 
R$47,756 in costs relating to terminations of employment contracts in this period.

(ii) Refers to the increase in the valuation allowance related to the deferred tax assets in 2017, 2016, and 2015. 
(iii) Refers  to  the  effects  of  the  difference  between  the  applicable  tax  rate  in  Brazil  and  the  tax  rates  applicable  to  other  Group 

companies located abroad. 

(iv) The main effects of nondeductible expenses refers to: (1) the effects of the adjustments of debt obligations due to the filing of the 
Bankruptcy  Petitions  and  based  on  the  Plan  of  R$26 million  (R$1.860 million  in  2016);  (2)  the  impairment  of  Unitel 
available-for-sale  investment  which  is  not  tax  deductible  in  the  amount  of  R$90 million  (R$371 million  in  2016  and 
R$152 million  in  2015)  (Note  24),  and  (3) the  impairment  of  goodwill  and  trademarks  for  the  Telecommunication  services  in 
Brazil and impairment of goodwill related to África, which is not tax deductible in the amount of R$16 million (R$77 million in 
2016 and R$91 million in 2015). 

(v) These  tax  incentives  correspond  mainly  to  a  75%  reduction  in  the  current  tax  due  on  operating  income  obtained  as  a  result  of 
telecommunication services rendered in certain northern and northeast regions of Brazil, where the Company holds facilities for 
the purpose of rendering those services. This tax benefit is usually granted for a 10 year period, limited up to January 1, 2024. 
(vi) Refers to a tax position taken in prior periods which were assessed by the taxing authorities. Although the Company believed in 
prior periods that these positions would more-likely-than-not of being sustained, it was decided to adhere to PRORELIT and avoid 
substantial costs to keep on going discussions with government. PRORELIT program allowed taxpayers to settle federal tax debts 
accrued prior to June 30th, 2015, excluding tax debts that are subject to tax installment payments.

In order to enroll, tax payers were requested to resign their litigation rights with respect to the settled debt amount and pay at least 
30% of their outstanding consolidated tax debt accrued through June 30th, 2015 in cash. The remaining 70% of the debt would be 
settled with tax loss carryforwards. Apart from the initial 30% down payment, no guarantees or collateral is needed. 

The Company  has submitted its application for PRORELIT to settle several  tax  debts.  Nevertheless, tax authorities have  a five 
years term to ratify the amounts of tax loss carryforwards utilized by taxpayers.

(i) Refer mainly to prepaid income tax and social contribution that will be offset against federal taxes payable in the future. 
(ii) Refer to withholding income tax (IRRF) credits on cash investments, derivatives, intragroup loans, government entities, and other 
amounts that are used as deductions from income tax payable for the years, and social contribution withheld at source on services 
provided to government agencies. 

(iii) For  the  year  ended  December 31,  2017,  total  valuation  allowance  increased  from  R$10,134,731  (6,239,713  in  2015)  to 
R$11,269,242, reflecting a net change in the valuation allowance totaling R$1,134,511 recognized for the companies that, as of 
December 31, 2017, do not expect to generate sufficient future taxable profits, based on consistent assumptions and timing used in 
the  analysis  of  the  potential  impairment  of  long-lived  assets  and  goodwill,  against  which  tax  assets  could  be  offset. Most  of 
deferred  tax  assets  have  been  reduced  by  a  valuation  allowance  to  the  amount  supported  by  reversing  taxable  temporary 
difference. The deferred tax assets not offset by valuation allowance are dependent upon the generation of future pretax income in 
certain  tax-paying  components  in  Brazil  that  have  a  history  of  profitability  and  an  expectation  of  continued  profitability. 
Management  believes  it  is  more  likely  than  not  that  the  results  of  future  operations  will  generate  sufficient  taxable  income  to 
realize the deferred tax assets that are not subject to the valuation allowance. However, deferred income tax assets can be reduced 
in the near term if estimates of future taxable income during the carryforward period are reduced. 

(iv) The  tax  loss  carryfowards  of  approximately  R$16,918,355  corresponding  to  R$5,752,241 million  of  deferred  tax  assets,  do  not 
expire, and may be carried forward indefinitely. The Company can offset their tax loss carryforwards against taxable income up to 
a limit of 30% per year, pursuant to the prevailing tax law. 

(v) Refer mainly the tax effects of foreign exchange liabilities, inflation adjustments of judicial deposits and tax incentives.

On June 20, 2016, the Company filed a request for judicial reorganization, which was granted by the RJ Judge on June 29, 2016 (Note 
1—Judicial Reorganization). Even though there are no indications in this regard, this circumstance indicates the existence of significant 
uncertainty  that may affect the Oi Companies’ ability to continue  as  going  concern basis.  Due to the aforementioned  conditions and 
circumstances the Company adjusted its recognition criteria for deferred income tax for the year 2016.

(i) Recoverable ICMS arises mostly from prepaid taxes and credits claimed on purchases of property, plant and equipment, which can 
be offset against ICMS payable within 48 months, pursuant to Supplementary Law 102/2000. Further, pursuant to Rio de Janeiro 
State Laws 7298/2016 and 7019/2015, the Company and its subsidiaries joined the program under which State Government debts 
can be offset against ICMS tax payable by the Company and its subsidiaries, as provided for by Articles 170 and 170-A of the 
National Tax Code and Article 190 of the Rio de Janeiro State Tax Code. 

(ii) Refers basically to the Social Integration Program Tax on Revenue (PIS) and Social Security Funding Tax on Revenue (COFINS) 

on revenue, financial income, and other income. 

The Company and its subsidiary Oi Móvel filed lawsuits claiming the deduction of State VAT (ICMS) from the tax base of Revenue 
Taxes  (PIS  and  COFINS)  and,  backed  by  a  favorable  appellate  court  decision  on  the  claim’s  merits,  suspended  the  payment  of  the 
revenue tax amount related to the state tax. During the period when the procedure was adopted, both companies recognized accounting

provisions  of  the  amounts  under  discussion,  in  both  cases  adjusted  for  inflation  using  the  Central  Bank’s  policy  rate  (SELIC).  The 
balances recognized as at December 31, 2016 referred to the unsettled PIS and COFINS amounts of December 2013-July 2014 and July 
2015-February 2017 for the Company, and November 2008, December 2013-July 2014, and July 2016-February 2017 for Oi Móvel, the 
collection of which was fully suspended in light of the mentioned court decision. 

In March 2017, the Federal Supreme Court (STF) declared the add-back of ICMS to the tax base of PIS and COFINS unconstitutional. 
Based on this decision and the opinion of its legal counsel that likelihood of an unfavorable outcome in those lawsuits became remote as 
from the STF’s decision, the Company reversed the provisions for contingencies related to the deduction of ICMS from the PIS and 
COFINS  tax  base,  recognized  for  the  aforementioned  periods,  through  the  date  said  decision  was  issued.  The  provision  reversal 
amounts is R$237 million and the recognized inflation adjustment amounts is R$45 million. 

It is worth noting that the STF could understand that applying the modulation mechanism to this decision, which is used to determine 
the  timing  effects  of  an  unconstitutionality  decision,  is  necessary.  Should  the  STF  apply  the  modulation  mechanism,  limiting  the 
decision’s  scope  in  time,  it  could  be  necessary  to  reassess  the  risk  of  an  unfavorable  outcome  in  said  lawsuits  and,  as  a  result,  to 
recognize new provisions for these contingencies in the future. However, even in this case, according to the Company’s and its legal 
counsel’s assessment, the likelihood of using the modulation mechanism to force taxpayers to pay unsettled tax debts related to taxable 
events prior to the STF’s decision is remote. 

(iii) Consisting basically of withholding tax on intragroup loans and interest on capital. 

11.     JUDICIAL DEPOSITS 

In some situations the Company makes, as ordered by courts or even at its own discretion to provide guarantees, judicial deposits to 
ensure the continuity of ongoing lawsuits. These judicial deposits can be required for lawsuits with a likelihood of loss, as assessed by 
the Company based on the opinion of its legal counselors, as probable, possible, or remote. 

As set forth by relevant legislation, judicial deposits are adjusted for inflation.

(i) As  mentioned  in  Note  2,  during  2017  the  Company  performed  a  reconciliation  of  the  judicial  deposits  and  as  a  result  of  that 
reconciliation  the  Company  recognized  a  write  off  in  prior  years  and  also  recorded  this  provision  for  estimated  losses  for  the 
judicial deposits that was estimated based on external information available (bank statements received from the depositaries and/or 
information obtained on the State Judicial Court’s website) and internal information available (internal systems).

(i)

Tax Compliance Program (PRT) 

The Company elected to include and settle under said tax refinancing program, created by the Federal Government, under Provisional 
Act  766/2017  (PRT),  the  administrative  proceedings  with  a  probable  likelihood  of  an  unfavorable  outcome  and  those  where,  while 
attributed a possible likelihood of an unfavorable outcome, the cost effectiveness of including them provided to be highly advantageous 
in light of the benefits offered by the program. 

The Company elected the payment method that allows settling 76% of the debt utilizing tax credits arising on tax loss carryforwards 
amounting  to  R$1,035 million,  and  paid  the  remaining  24%  in  24  monthly  installments  totaling  R$327 million  plus  SELIC  interest 
charged  as  from  the  adherence  month.  All  the  procedures  necessary  for  the  Company  joining  the  PRT  were  completed  within  the 
statutory deadline, while MP 766/2017 was still in effect. 

Subsequently, on June 1, 2017 the effective period of said Provisional Act ended because it was not passed into law within the relevant 
constitutional deadline. However, as established by the Federal Constitution, the legal relationships established and arising from actions 
taken  while  a  provisional  act  not  passed  into  law  was  effective,  as  in  the  case  of  the  Company’s  joining  the  PRT,  continue  to  be 
governed by the former provisional act, except where the National Congress provides for otherwise, by means of a legislative decree. 

Note that the PRT, governed by MP 766/2017, is not equivalent to the tax installment plan established by MP 783/2017 (PERT), of 
May 31, 2017, because of differences in payment terms and conditions, plan scope, and access requirements. 

(ii) Special Tax Compliance Program (PERT) 

The Company elected to include in and settle through PERT only tax debts that in aggregate do not exceed the fifteen million Brazilian 
reais (R$15,000,000) ceiling set by Article 3 of Law 13496/2017. 

The  tax  debts  included  in  said  program  were  those  being  disputed  at  the  administrative  level  in  proceedings  classified  with  a  low 
likelihood of the Company winning and which, in the event of an unfavorable outcome, would result in a lawsuit—and entail all the 
associated costs—, the reason why the cost effectiveness of joining the program was quite positive, because of the benefits offered by 
PERT (especially the payment of just 5% of the debt in cash).

Preferred shares are nonvoting, but are assured priority in the payment of the noncumulative minimum dividends equal to the higher of 
6%  per  year  of  the  amount  obtained  by  dividing  capital  stock  by  the  total  number  of  shares  of  the  Company  or  3%  per  year  of  the 
amount obtained by dividing book equity by the total number of shares of the Company. 

The Company is authorized to increase its capital under a Board of Directors’ resolution, in common and preferred shares, up to the 
share capital limit of R$34,038,701,741.49, within the legal limit of 2/3 for the issuance of new nonvoting preferred shares. 

By  resolution  of  the  Shareholders’  Meeting  or  Board  of  Directors’  Meeting,  the  Company’s  capital  can  be  increased  by  capitalizing 
retained earnings or reserves previously set up for this purpose by the Shareholders’ Meeting. Under these conditions, the capitalization 
can be made without any change in the number of shares. 

Capital  is  represented  by  common  and  preferred  shares  with  no  par  value.  The  Company  is  not  required  to  maintain  the  current 
proportion of common to preferred share on capital increases. 

On  February 25,  2015  the  Board  of  Directors  approved  a  capital  increase  of  R$154  without  the  issue  of  new  shares,  through  the 
capitalization of the investment reserve. 

In October 2015, the voluntary conversion of Company preferred shares into common shares was completed (Note 1).

(ii) On February 27, 2012, the Extraordinary Shareholders’ Meeting of the Company approved the Merger Protocol and Justification 
of TNL with and into the Company, and the Company’s shares then held by TNL, as a result of the merger of Coari with and into 
the Company, were canceled, except for 24,647,867 common shares that remained in treasury; 

(iii) Starting April 9, 2012, Oi paid the reimbursement of shares to withdrawing shareholders. 

(iv) As  a  result  of  the  Company’s  capital  increase  approved  by  the  Board  of  Directors  on  April 30  and  May 5,  2014,  and  due  to 

subscription made by Pharol in PT Portugal assets, R$263,028 was reclassified to treasury shares. 

(v) Under  the  exchange  agreement  entered  into  with  Pharol  on  September 8,  2014  (Note  26),  approved  at  Pharol’s  extraordinary 
shareholders’  meeting,  by  the  Brazilian  Securities  and  Exchange  Commission—CVM,  and  at  the  Company’s  extraordinary 
shareholders’  meeting,  on March 30, 2015  the  Company conducted a  share exchange under  which  Pharol  delivered to PTIF Oi 
shares divided into 474,348,720 OIBR3 shares and 948,697,440 OIBR4 shares (47,434,872 and 94,869,744 after the reverse stock 
split,  respectively);  in  exchange,  the  Company  delivered  Rio  Forte  securities  to  PT  SGPS,  in  the  total  principal  amount  of

Dividends and interest on capital 

Dividends are calculated pursuant to the Company’s Bylaws and the Brazilian Corporate Law. Preferred dividends or priority dividends 
are calculated pursuant to the Company’s Bylaws. 

Preferred shares are nonvoting, but are assured priority in the payment of the noncumulative minimum dividends equal to the higher of 
6%  per  year  of  the  amount  obtained  by  dividing  capital  stock  by  the  total  number  of  shares  of  the  Company  or  3%  per  year  of  the 
amount obtained by dividing book equity by the total number of shares of the Company. 

By decision of the Board of Directors, the Company can pay or credit, as dividends, interest on capital pursuant to Article 9, paragraph 
7, of Law 9249/1995. The interest paid or credited will be offset against the annual mandatory minimum dividend amount, pursuant to 
Article 43 of the Bylaws. 

The mandatory minimum dividends, which are calculated pursuant to Article 202 of Law 6404/1976 (Brazilian Corporate Law), were 
not calculated because the Company reported losses in 2017, 2016 and 2015. 

(e)

Share issue costs 

This line item includes the share issue costs net of taxes amounting to R$377,429, of which R$194,464 is taxes. These costs are related 
to  the  following  corporate  transactions:  (1) capital  increase,  in  accordance  with  the  plan  for  the  business  combination  between  the 
Company and Pharol and (2) the corporate reorganization of February 27, 2012, and (3) merger of TmarPart with and into Oi. These 
costs directly attributable to the mentioned events are basically represented by expenses on the preparation of prospectus and reports, 
third-party professional services, fees and commissions, transfer costs, and registration costs. 

(f)

Other comprehensive income 

The Company recognizes in this line item other comprehensive income, which includes hedge accounting gains and losses, actuarial 
gains  and  losses,  foreign  exchange  differences  arising  on  translating  the  net  investment  in  foreign  subsidiaries,  and  the  tax  effects 
related to these components, which are not recognized in the statement of profit or loss.

For purposes of the pension plans described in this note, the Company can also be referred to as the “Sponsor”. 

The sponsored plans are valued by independent actuaries at the end of the annual reporting period. The Bylaws provide for the approval 
of the pension plan policy, and the joint liability attributed to the defined benefit plans is governed by the agreements entered into with 
the pension fund entities, with the agreement of the National Pension Plan Authority (PREVIC), as regards the specific plans. PREVIC 
is the official agency that approves and oversees said plans. 

The  sponsored  defined  benefit  plans  are  closed  to  new  entrants  because  they  are  close-end  pension  funds.  Participants’  and  the 
sponsors’ contributions are defined in the funding plan.

PAMA is a multiemployer healthcare plan for retired employees aimed at providing medical care to beneficiaries, with copayments by 
and contributions from the latter. The PAMA plan has been closed to new members since February 2000, other than new beneficiaries 
of current members and employees that are covered by the PBS-A plan who have not yet elected to join the PAMA plan. In December 
2003, the Company began  sponsoring  the  PCE  –Special  Coverage Plan, or the PCE plan, a health-care plan managed by Sistel. The 
PCE plan is open to employees that are covered by the PAMA plan. From February to July 2004, December 2005 to April 2006, June to 
September 2008, July 2009 to February 2010, March to November 2010, February 2011 to March 2012 and March 2012 until today, the 
Company offered incentives to its employees to migrate from the PAMA plan to the PCE plan. 

In  October  2015,  in  compliance  with  a  court  order,  Sistel  transferred  the  surpluses  of  the  PBS-A  benefits  plan,  amounting  to 
R$3,042 million,  to  ensure  the  solvency  of  the  plan  PAMA.  Of  the  total  amount  transferred,  R$2,127 million  is  related  to  the  plans 
sponsored by the Company, apportioned proportionally to the obligations of the defined benefit plan. 

As of December 31, 2017, the PAMA plan had a surplus of R$395,359. No significant contribution in 2017, 2016 and 2015. 

3)

PAMEC-BrT—Assistance plan managed by the Company 

Defined  benefit  plan  intended  to  provide  medical  care  to  the  retirees  and  survivor  pensioners  linked  to  the  TCSPREV  pension  plan 
managed by FATL. 

The contributions for PAMEC-BrT were fully paid in July 1998, through a bullet payment. However, as this plan is now administrated 
by the Company, after the transfer of management by Fundação 14 in November 2007, there are no assets recognized to cover current 
expenses, and the actuarial obligation is fully recognized in the Company’s liabilities.

Investment policy of the plans 

The investment policies and strategies for the two single-employer benefit pension plans PBS-Telemar and TelemarPrev are subject to 
Resolution N° 3,121 of the National Monetary Council, which establishes investment guidelines. 

TelemarPrev is a defined contribution plan with individual capitalization. Management allocates the investments in order to conciliate 
the  expectations of the sponsors, active and assisted  participants.  The assets on  December 31,  2017  consists  mainly  of the following 
portfolio: 91% in debt securities, 5% in equity of Brazilian companies and 4% in real estate and other assets. 

PBS-Telemar  plan  is  closed  for  new  participants  and  the  vast  majority  of  the  current  participants  are  receiving  their  benefits.  The 
mathematical reserves are readjusted annually considering an interest rate of 6% per annum over the variation of the National Consumer 
Price  Index  (“INPC”).  Therefore,  management’s  strategy  is  to  guarantee  resources  that  exceed  this  readjustment.  Management  also 
prepares a long-term cash-flow to match assets and liabilities. Therefore, debt securities investments are preferred when choosing the 
allocation of its assets, representing 89% of the portfolio in December 31, 2017. 

The investment policies and strategies for BrTPREV, TCSPREV and PAMEC, which is approved annually by the pension fund’s board 
states that the investment decisions should consider: (i) capital preservation; (ii) diversification; (iii) risk tolerance; (iv) expected returns 
versus benefit plan’s interest rates; (v) compatibility between investments liquidity and pensions’ cash flows and (vi) reasonable costs. 
It  also  defines  volume  ranges  for  the  different  types  of  investment  allowed  for  pension  funds,  which  are:  domestic  fixed  income, 
domestic  equity,  loans  to  pension  fund’s  members  and  real  estate.  In  the  fixed  income  portfolio,  only  low  credit  risk  securities  are 
allowed. 

Derivative  instruments  are  only  permitted  for  hedging  purposes.  Loans  are  restricted  to  certain  credit  limits.  Tactical  allocation  is 
decided by the investment committee, consisted of the pension fund’s officers, investment manager and one member designated by the 
Board. Execution is performed by the Finance Department.

(c) Share-based compensation 

The  Long-term  Incentive  Program (2015-2017), approved by the  Company’s  Board  of Directors  on  March 13, 2015, seeks  a greater 
alignment with the Company’s management cycle and business priorities. The Program consists of the payment of gross cash reward, in 
accordance with the Laws and Regulations, as a result of the compliance with the goals set for 2015-2017. The gross cash reward is 
benchmarked  to  the  quotation  of  Company  shares.  The  Company  also  disclose  that  the  beneficiaries  are  not  entitled  to  receiving 
Company shares since the Program does not provide for the transfer of shares to its beneficiaries. 

23.     SEGMENT INFORMATION 

The  Company  uses  operating  segment  information  for  decision-making.  The  Company  identified  only  one  operating  segment  that 
corresponds to the telecommunications business in Brazil. 

In addition to the telecommunications business in Brazil, the Company conducts other businesses that individually or in aggregate do 
not meet any of the quantitative indicators that would require their disclosure as reportable business segments. These businesses refer 
basically  to  the  following  companies:  Companhia  Santomense  de  Telecomunicações,  Listas  Telefónicas  de  Moçambique,  ELTA  – 
Empresa  de  Listas  Telefónicas  de  Angola,  and  Timor  Telecom,  which  provide  fixed  and  mobile  telecommunications  services  and 
publish telephone directories, and which have been consolidated since May 2014. 

The revenue generation is assessed by the Company based on a view segmented by customer, into the following categories: 

• Residential Services, focused on the sale of fixed telephony services, including voice services, data communication services 

(broadband), and pay TV; 

•

•

Personal  Mobility,  focused  on  the  sale  of  mobile  telephony  services  to  subscription  and  prepaid  customers,  and  mobile 
broadband customers; and 

SMEs/Corporate, which includes corporate solutions offered to small, medium-sized, and large corporate customers. 

No single customer represent more than 10% of revenues neither 10% of receivables,

Approval of preparatory actions for the sale of Africatel 

At the Board of Directors’ meeting held on September 16, 2014, the Company’s management was authorized to take all the necessary 
actions to divest the Company’s stake in Africatel, representing at the time 75% of Africatel’s share capital, and/or dispose of its assets. 
Oi would lead the sale process, even though it believes that it would be in the best interests of both Africatel shareholders to maximize 
the value of their investments, that this sale be coordinated with Samba Luxco, a Helios Investors L.P. affiliate that held the remaining 
25% of Africatel’s share capital. Oi was committed to working with its local partners and each one of the operating companies where 
Africatel holds investments to ensure a coordinated transition of its interests in these companies. 

Notwithstanding  the  above,  the  indirect  subsidiary  Africatel  GmbH &  Co.  KG  (“Africatel  GmbH”),  direct  holder  of  the  Company’s 
investment in Africatel, received on September 16, 2014 a letter from Samba Luxco, where Samba Luxco exercised an alleged right to 
sell the shares it holds in Africatel (put option), pursuant to Africatel’s shareholders’ agreement. According to this letter, this put option 
results from the indirect transfer of Africatel shares, previously indirectly held by Pharol, to the Company as the payment for the capital 
increase made in May 2014. In the letter, Samba Luxco purported to exercise the alleged put right and thereby required Africatel GmbH 
to acquire its shares in Africatel. 

The Company believes that there was not any action or event that, under Africatel’s shareholders’ agreement terms, would trigger the 
right  to  exercise  the put  option.  Accordingly, without  prejudice to  the  value  the Company  attributes  to maintaining a  relationship  of 
mutual respect with Samba Luxco, Africatel GmbH decided to challenge the exercise of this put option by Samba Luxco, pursuant to 
Africatel’s  shareholders’  agreement,  which  was  duly  notified  in  Africatel  GmbH’s  reply  to  Samba  Luxco’s  letter,  on  September 26, 
2014. 

Thus,  on  November 12,  2014,  the  International  Court  of  Arbitration  of  the  International  Chamber  of  Commerce  notified  Africatel 
GmbH  that  Samba  Luxco  had  commenced  arbitral  proceedings  against  Africatel  GmbH  to  enforce  its  purported  put  right  or,  in  the 
alternative,  certain  ancillary  rights  and  claims.  Africatel  GmbH  presented  its  reply  to  Samba  Luxco’s  request  for  arbitration  on 
December 15, 2014. The arbitral tribunal was constituted on March 12, 2015 and Africatel GmbH filed its defense on October 9, 2015. 

At the same time it intended to vigorously defend Africatel GmbH in this proceeding, Oi also focused its efforts on the sale of Africatel 
and/or its assets, since the Company believed that if this goal were successfully met, the initiated arbitration proceeding would lose its 
purposes. 

On  June 16,  2016,  PT  Participações,  Africatel  GmbH  and  Africatel,  and  Company  subsidiaries,  entered  into  a  series  of  contractual 
agreements with Samba Luxco, with the primary purpose of resolving and terminate the arbitration proceeding.

The  agreements  entered  into  include  the  amendments  to  Africatel’s  Shareholders’  Agreement  and  a  Settlement  and  Share  Exchange 
Agreement  (“SSEA”),  under  which  Samba  Luxco  should,  upon  the  implementation  of  the  agreement:  (i) terminate  the  ongoing 
arbitration  proceeding  and  exempt  the  Company’s  subsidiaries  with  regard  to  all  the  past  and  current  demands  related  to  alleged 
breaches of Africatel’s Shareholders’ Agreement and raise in the arbitration proceeding, (ii) waive certain approval rights it had under 
Africatel’s  Shareholders’  Agreement,  and  (iii) transfer  to  Africatel  11,000  Africatel  shares,  each  with  a  par  value  of  €1.00,  thus 
decreasing Samba Luxco’s stake in Africatel from 25% to 14%. In exchange, Africatel BV should transfer to Samba Luxco its current 
stake  of  approximately  34%  in  the  capital  of  the  Namibian  telecommunications  operator  Mobile  Telecommunications  Limited 
(“MTC”). 

On January 31, 2017, since all the required regulatory and anti-competition approvals were obtained and all other contractual terms and 
conditions were complied, the transactions provided for in the contractual agreements entered into on June 16, 2016 were obtained. As a 
result, Samba Luxco reduced its stake in Africatel to 14,000 shares and the latter transferred to Samba Luxco entire its stake in MTC. 

Samba  Luxco  also  irrevocably  and  unconditionally  held  harmless  Africatel  GmbH,  Africatel,  Pharol,  and  their  associates  and  their 
successors from all claims presented in the arbitration proceeding. The parties required the arbitration court constituted pursuant to the 
International Chamber of Commerce to issue a Consent Sentence to register the terms of the agreement established in the SSEA, and 
accordingly,  the  arbitration  proceeding  was  terminated  and  Oi  subsidiaries  received  a  settlement  of  all  past  and  current  demands  of 
Samba Luxco related to the alleged violations of Africatel’s Shareholders’ Agreement, raised during the arbitration proceeding. 

Subsequently, on March 29, 2017, Africatel GmbH and Samba Luxco approved, in a Shareholders’ Resolution, the cancellation of the 
11,000 Africatel shares that Samba Luxco had transferred to the latter and which were held in treasury. The shareholders also approved 
the cancellation of an additional 1,791 Africatel shares held by Samba Luxco, and as a result the stakes of Africatel GmbH and Samba 
Luxco in Africatel changed to 86% and 14%, respectively. 

The effects of the assignment/transfer among shareholders of Africatel’s 34% stake in subsidiary MTC – Mobile Telecommunications 
Limited, in exchange for the reduction of the non-controlling shareholder’s stake, Samba Luxco, in Africatel were R$145,787 in equity 
attributable to owners of the company and R$228,343 in equity attributable to non-controlling interests. 

With regards to Africatel’s indirect stake in Unitel, through its subsidiary PT Ventures, it is worth noting that on October 13, 2015 PT 
Ventures  initiate  the  arbitration  proceeding  against  Unitel’s  shareholders  as  a  result  of  the  violation  by  the  latter  of  several  rules  of 
Unitel’s shareholders’ agreement and the Angolan law, including the fact that such shareholders caused Unitel not to pay the dividends 
paid to PT Ventures and retain the information and clarifications on such payment. On October 14, 2016, PT Ventures filed its initial 
arguments,  together  with  a  report  issued  by  a  financial  specialist.  The  amount  claimed  by  PT  Ventures  is  US$3,036,494,891,  plus 
interest accrued through the actual payment date by the Defendants, totaling US$3,400,847,957 on October 14, 2016, according to the 
financial  specialist’s  report.  An  arbitration  judgment  hearing  was  held  from  February 7  to  16,  2018,  where  each  party  presented  its 
arguments and the factual witnesses and experts from each side were heard.

Additionally,  on  October 20,  2015,  PT  Ventures  filed  an  action  for  a  declaration  of  sentence  against  Unitel  with  an  Angolan  court, 
claiming the recognition of PT Ventures’ right to receive the outstanding dividends declared in 2010, and the dividends for the years 
2011, 2012, and 2013. 

The  other  shareholders  of  Unitel  have  asserted  to  PT  Ventures  that  they  believe  that  Pharol’s  sale  of  a  non-controlling  interest  in 
Africatel to Samba Luxco in 2007, and the indirect transfer of Unitel shares previously indirectly held by Pharol to the Company to pay 
in  the  capital  increase  complete  in  May  2014,  constituted  a  breach  the  Unitel  shareholders’  agreement.  PT  Ventures  disputes  this 
interpretation of the relevant provisions of the Unitel shareholders’ agreement and believes that such provisions apply only to a transfer 
of Unitel shares by PT Ventures itself. By the date of this report, the Company had not been notified of any proceedings initiated with 
respect to Pharol’s sale of a non-controlling stake in Africatel to Samba Luxco. 

The assets of the African operations are stated at the lower of their carrying amounts and their fair values less costs to sell. The sale of 
the  African  assets  is  being  actively  marketed  and  the  Company  has  received  some  indications  of  interest.  The  PRJ  prepared  by  the 
Company  and  approved  by  the  creditors  and  the  Court,  includes  an  additional  measure  to  obtain  cash  related  with  the  sale  of 
international assets. 

The African operations are consolidated in the statement of profit or loss since May 5, 2014.

(i)

This caption  refers to the  estimated  recoverable  amount of dividends  and correspondent interests receivable  from Unitel. As of 
December 31,  2017  gross  amount  of  unpaid  dividends  by  Unitel  to  PT  Ventures  totaled  US$796 million  and  refers  to  the 
distribution of accumulated earnings in 2009 and the distribution of profits for fiscal years 2011, 2012, 2013, and 2014. In order to 
estimate the present value of the recoverable amount of unpaid dividends the Company takes into account (1) its legal advisors’ 
opinion  regarding  the  outcome  of  the  law  suits  filed  in  a  Angolan’s  Court  and  Paris’  ICC  to  collect  this  amounts  from  Unitel, 
(2) the liquidity position of Unitel as of December 31, 2017, (3) the decision of Unitel to accrue interests on the delayed payments 
and (4) a weight average cost of capital and an interest rate for accrual of interests; 

(ii) Refers mainly to the fair value of the indirect interest financial investment of 25% of Unitel’s share capital, classified as held for 
sale.  As  at  December 31,  2017  the  estimated  fair  value  of  the  investment  in  Unitel  was  R$1,920 million  (R$1,995 million  at 
December 31, 2016). The fair value of this investment is computed by the Company using a discounted cash-flow methodology, 
which  includes  (1) cash  flows  forecasts  for  a  five-year  period,  (2) a  1,5%  growth  rate  to  extrapolate  the  cash  flows  projections 
(1,5% in 2016), (3) exchange rate forecasts of Angolan Kwanza and (4) a weight average cost of capital of 17.1% (19% in 2016), 
which  was  computed  based  on  financial  market  information  and  on  the  assessment  of  the  management  regarding  the  business 
environment and relationship with the others shareholders and Unitel itself. The Company monitors and periodically updates the 
main  assumptions  used  in  the  fair  value  measurement  considering  the  changes  occurred  in  financial  market  conditions  and  the 
impacts of news events related to the investment, notably the lawsuits filed against Unitel and its shareholders in Angolan Courts 
and ICC Paris. 

(iii) The reduction in goodwill is primarily represented by the implementation of, in the first quarter of 2017, the transactions provided 
for in the contractual instruments entered into with Samba Luxco, which reduced its stake in Africatel, while Africatel transferred 
to  Samba  Luxco  its  entire  stake  in  MTC.  In  December  2017,  annual  impairment  tests  were  conducted  based  on  the  internal 
valuation made,  including  cash flows  forecasts for  a five-year period, the  choice of a  growth rate to extrapolate  the cash flows 
projections, and definition of an appropriate discount rate, calculated based on the weight average cost of capital of from 11.7% to 
17.7%, taking into consideration Africans business environment. 

(iv) Represented mainly by the Samba Luxco’s 14% stake in Africatel and, consequently, in its net assets.

On June 30, 2014, the Company was informed, through a notice disclosed by Pharol, of the investment made by PTIF and PT Portugal, 
companies contributed by Pharol to Oi in the capital increase, in a commercial paper of Rio Forte Investments S.A. (“Securities” and 
“Rio  Forte”,  respectively),  a  company  part  of  the  Portuguese  group  Espírito  Santo  (“GES”),  when  both  PTIF  and  PT  Portugal  were 
Pharol subsidiaries. 

According to said notice, the Securities had been issued in the total amount of €897 million, and bore average annual interest of 3.6% 
and matured on July 15 and July 17, 2014 (€847 and €50 million, respectively), stressing that since April 28, 2014 no other investment 
and/or renewal of this type of investments had been made. 

Both  PT  Portugal  and  PTIF  (collectively  “Oi  Subsidiaries”)  became  Company  subsidiaries  due  to  the  assignment  of  all  PT  Portugal 
shares to the Company by Pharol, on May 5, 2014, to pay in the Company’s capital increase approved on April 28 and 30, 2014. 

The Securities matured in July 2014 and subsequent the cure period for payment of the securities ended without Rio Forte paying the 
amount due. The Luxembourg Commercial Court denied Rio Forte’s request for controlled management on October 17, 2014 and Rio 
Forte’s bankruptcy was declared on December 8, 2014. 

Agreements entered into by the Company, TmarPart, and Pharol related to the cash investments made in Rio Forte commercial 
papers 

On September 8, 2014, after obtaining the due corporate approvals, the Company, Oi Subsidiaries, TmarPart, and Pharol entered into 
definitive agreements related to the investments made in the Securities. The agreements provided for (i) an exchange (the “Exchange”) 
through which Oi Subsidiaries transferred the Securities to Pharol in exchange for preferred and common shares of the Company held 
by Pharol, as well as (ii) the assignment by Oi Subsidiaries of a call option on the Company shares to the benefit of PT (“Call Option”). 

On  March 26,  2015,  in  order  to  comply  with  the  conditions  presented  by  the  CVM’s  Board  to  grant  the  waivers  necessary  for  the 
implementation  of  the  Share  Exchange  and  Put  Option,  according  to  the  decision  issued  on  March 4,  2015,  the  Company  held  a 
Shareholders’ Meeting which approved the terms and conditions of the Share Exchange and Put Option agreements. 

On  March 31,  2015,  the  Company  announced  in  a  Material  Fact  Notice,  the  consummation  of  the  Exchange,  under  which  Pharol 
delivered to PTIF  unencumbered  Oi shares  corresponding to 47,434,872 OIBR3 (common shares) and 94,869,744 OIBR4 (preferred 
shares)  (“Exchanged  Shares”);  and  in  exchange  Oi,  through  PTIF,  delivered  the  Securities  to  Pharol,  totaling  €897 million,  with  no 
money involved.

With  implementation  of  the  Exchange,  Pharol  became  the  holder  of  the  Securities  and  the  sole  responsible  for  negotiating  with  Rio 
Forte and the decisions related to the Securities, and the Company is responsible for the supporting documentation to Pharol to take the 
necessary actions to collect the receivables represented by the Securities. 

As  a  result  of  the  consummation  of  the  Exchange,  Pharol’s  direct  interest  in  Oi  decreased  from  104,580,393  common  shares  and 
172,025,273 preferred shares, representing 37.66% of the voting capital (ex-treasury) and 32.82% of the total capital of Oi (ex-treasury) 
to 57,145,521 common shares and 77,155,529 preferred shares, representing 24.81% of the voting capital (ex-treasury) and 19.17% of 
the total capital of Oi (ex-treasury). 

Main terms of the Call Option for the Purchase of Shares (“Option Contract”) 

Under the Call Option Agreement entered into on September 8, 2014 by Pharol, PTIF, PT Portugal, Oi, and TmarPart, the call option 
became exercisable with the consummation of the Exchange, beginning March 31, 2015, at any time, during a six-year period. 

Under the terms of the Call Option Agreement, the Call Option will involve 47,434,872 Oi common shares and 94,869,744 Oi preferred 
shares  (“Shares  Subject  to  the  Option”)  and  can  be  exercised,  in  whole  or  in  part,  at  any  time,  pursuant  to  the  following  terms  and 
conditions: 

(i)  Term:  six  (6) years,  noting  that  Pharol’s  right  to  exercise  the  Option  on  the  Shares  Subject  to  the  Option  will  be  reduced  by  the

Option. The exercise price of the shares will be paid in cash, at the transfer date of the Shares Subject to the Option. 

By March 31, 2017, Pharol had not exercised the Option, in whole or in part, on the Shares Subject to the Option. Accordingly, since 
March 31, 2016, 4,743,487 common shares and 9,486,974 preferred shares issued by the Company, equivalent to 10% of  the Shares 
Subject to the Option and since March 31, 2017, another 8,538,277 common shares and 17,076,554, equivalent to 18% of the Shares 
Subject to the Option are no longer subject to the Option. 34,153,108 common shares and 68,306,216 preferred shares are still subject 
to the Option.

Oi is not required to maintain the Exchanged Shares in treasury. In the event that PTIF or any of The Company’s subsidiaries do not 
hold, in treasury, a sufficient number of Shares Subject to the Option to transfer to Pharol, the Option may be financially settled through 
payment by Oi Subsidiaries of the amount corresponding to the difference between the market price of the Shares Subject to the Option 
and the respective exercise price corresponding to these shares. 

While the Option remains effective, Pharol may not purchase Oi shares, directly or indirectly, in any manner other than by exercising 
the Option. Pharol may not transfer or assign the Option, nor grant any rights under the Option, including security, without the consent 
of  Oi.  If  Pharol  issues,  directly  or  indirectly,  derivatives  that  are  backed  by  or  referenced  to  Oi  shares,  it  shall  immediately  use  the 
proceeds derived from such a derivative transaction, directly or indirectly, to acquire the Shares Subject to the Option. 

Oi may terminate the Option if (i) the Bylaws of Pharol are amended voluntarily to remove or amend the provision that limits the voting 
right to 10% of all votes corresponding to the capital stock of Pharol; (ii) Pharol directly or indirectly engages in activities that compete 
with  the  activities  of  Oi  or  its  subsidiaries  in  the  countries  in  which  they  operate;  (iii) Pharol  violates  certain  obligations  under  the 
Option Contract. 

On March 31, 2015, the Option Agreement was amended to provide for (i) the possibility of Pharol assigning or transferring the Call 
Option, regardless of previous consent by Oi, provided that such assignment or transfer covers at least  1⁄4 of the Shares Subject to the 
Option, and Pharol can freely use the proceeds of such transactions, (ii) the possibility of Pharol, subject to previous, written consent 
from Oi, creating or granting any rights arising on the Call Option or, pledging the guarantees supported by the Call Option, and (iii) the 
grant of a right of first refusal to Oi for the acquisition of the Call Option, should Pharol wish to sell, assign, transfer, contribute the 
capital of another entity, transmit, or otherwise sell or dispose of the Call Option. 

This amendment has been executed with a suspensive condition and would be only effective after an authorization from the CVM to 
amend the Option Agreement were granted. However, at a meeting held on December 16, 2015, the CVM’s board decided to refuse the 
entire request filed by the Company for waiver of the requirements of CVM Instructions 10/1980 and 390/2003 to amend the Option 
Agreement. 

These Instructions determine that the acquisition and sale of shares of a publicly held company must be conducted in a stock exchange 
and that the stock options transactions of a publicly held company must be conducted in the markets where the company’s shares are 
traded, and interdicts any private transactions. The waiver of these requirements would allow the enforcement of the provisions of the 
amendment  to  the  Call  Option  Agreement  related  to  (i) the  possibility  of  privately  transferring  the  Call  Option  from  Pharol  to  Oi; 
(ii) granting  a  right  of  first  refusal  to  Oi  to  acquire  the  Call  Option;  and  (iii) the  possibility  of  making  the  payment  of  the  Option 
acquisition price in Oi shares, if the right of first refusal if exercised.

As  at  December 31,  2017,  the  fair  value  of  the  Call  Option  is  estimated  at  R$13 million  calculated  by  the  Company  using  the

Actions to suspension of payments of Oi Holanda and PTIF 

On  August 9,  2016  and  September 30,  2016,  due  to  the  risk  of  the  Judicial  Reorganization  process  in  Brazil  not  being  directly 
recognized in the Netherlands, as based on some treaty or regulation, Oi Holanda and PTIF separately filed requests to suspension of 
payments (“verzoekschrift tot aanvragen surseance van betaling”) with the Amsterdam District Court and concurrently filed the draft of 
the composition with creditors plan (“akkoord” or “Composition Plan”). 

The requests filed to suspension of payments of Oi Holanda and PTIF were temporarily granted by the Amsterdam District Court on 
August 9, 2016 and October 3, 2016, respectively. In the decision that granted the payment stay request, the court appointed as trustees 
in the Netherlands (collectively, the “Dutch Trustees”) in the Netherlands for Oi Holanda and PTIF. 

On December 1, 2016, the Dutch Trustees submitted requests to convert PTIF and Oi Holanda payments suspension proceedings into 
bankruptcy (collectively, the “Conversion Requests”). On January 12, 2017, the Dutch Court held hearings to decide on the Conversion 
Requests, at which occasion the Dutch Court informed that it would issue a decision on this matter on January 26, 2017. However, On 
January 26, 2017 the decision on the Conversion Requests was postponed to February 2, 2017, and on this date the Dutch Court rejected 
the Conversion Requests, thus maintaining the Suspension of Payments lawsuits of Oi Holanda and PTIF. 

On  February 10,  2017,  certain creditors  filed  appeals  against the  decisions  that  rejected  the Conversion Requests  of  Oi  Holanda  and 
PTIF  (“Appeals”).  On  February 20,  2017,  the  Amsterdam  Appellate  Court,  in  the  Netherlands,  set  the  hearings  on  the  appeals  to 
March 29, 2017. On March 29, 2017, the hearings were held and the Dutch Appellate Court informed that it intended to disclose the 
related decisions on April 19, 2017. On April 19, 2017, said Appellate Court upheld the Appeals and determined that the suspension of 
payments proceedings of Oi Holanda and PTIF be converted into bankruptcy proceedings in the Netherlands. These decisions of the 
Dutch Appellate Court are restricted to its jurisdiction and the Dutch laws, are not final, and were subject to the appeals lodged by Oi 
Holanda and PTIF with the Dutch Supreme Court on May 1, 2017. On July 7, 2017, the Dutch Supreme Court overruled the appeals 
filed  by  Oi  Holanda  and  PTIF  and  upheld  the  decisions  of  the  Dutch  Appellate  Court  that  the  proceedings  must  be  converted  into 
bankruptcy proceedings in the Netherlands. These Dutch Supreme Court decisions have no impact in Brazil while they are not ratified 
by the Brazilian Superior Court of Justice (and the Company is not aware that a proceeding aimed at such ratification has been initiated) 
and other jurisdictions that acknowledge the competence of the Brazilian courts to process the Judicial Reorganization.

On April 10, 2018, PTIF and Oi Holanda filed with the Dutch Court their composition plans—the terms of which are similar to those of 
the  JRP  approved  by  the  creditors  at  the  Creditor’  General  Meeting  on  December 19  and  20,  2017  and  ratified  by  the  Judicial 
Reorganization Court on January 8, 2018(“Composition Plan” or “Composition Plans”)—and require setting dates for the submission of 
claims and a vote on the Composition Plans, which was granted by the Dutch Court on the same date, which set May 17, 2018 as the 
deadline for the submission of claims and June 1, 2018 to hold a vote on each Composition Plan. 

On  the  same  date,  i.e.,  April 10,  2018,  Oi  released  a  Notice  to  the  Market  informing  about  the  decision  above  and  the  detailing  the 
consent  solicitation  procedure  to  PTIF’s  and  Oi  Holanda’s  for  purposes  of  voting  on  their  Composition  Plan  to  be  granted  by  the

Lawsuits in the Netherlands 

Syzygy Capital Management, Ltd., Loomis Sayles Strategic Income Fund, and two groups of Italian bond holders: (i) Sandro Boscolo 
Bragadin, Stefano Crispo, Paolo Denicoli, Ivano Falceri, Alex Lo Furno, Dario Farina, Aldo Fazzini, Walter Masoni, Salvatore Lucio 
Marcuccio,  Luca  Marsili,  Aniello  Aatrone,  Vincenzo  Matrone,  Mario  Parcianello,  Francesca  Risicato,  Antonio  Scalzullo,  Giovanni 
Marcheselli,  Nadia  Benedett,  and  (ii) Allesandro  Callegari,  Stefano  Capodarca,  Banco  Consulia  S.P.A.,  Valentina  Basso,  and  Piero 
Basso, have filed to date request for the declaration of bankruptcy of Oi Holanda with the Amsterdam District Court on June 27, 2016, 
July 8, 2016, July 11, 2016, and June 15, 2016, respectively. 

Citicorp Trustee Company Limited, the trustee of the bonds issued by PTIF, filed on August 22, 2016 a request for the declaration of 
bankruptcy of PTIF with the Amsterdam District Court. 

The bankruptcy requests referred to above remained suspended because Oi Holanda and PTIF filed payment suspension lawsuits. 

On  December 23,  2016,  Citadel  Horizon  S.à.r.l.,  Citadel  Equity  Fund  Ltd.,  Syzygy  Capital  Management  Ltd.,  Trinity  Investments 
Designated  Activity  Company,  and  York  Global  Finance  Fund  L.P.  filed  requests  for  the  conversion  of  Oi  Holanda’s  payment 
suspension  action  into  bankruptcy  with  the  Amsterdam  District  Court.  Citadel  Horizon  S.à.r.l.  withdrew  its  request  because  it  was 
proven  that  it  is  not  an  Oi  Holanda  creditor.  The  requests  of  the  other  creditors  were  rejected  on  February 2,  2017  under  the  same 
decision that rejected the Conversion Requests filed by the Dutch

Trustees  since  the  foundations  of  all  these  requests  were  similar.  On  February 20,  2017,  the  Amsterdam  Appellate  Court,  in  the 
Netherlands, set the hearings on the appeals to March 29, 2017. On March 29, 2017, the hearings were held and the Appellate Court 
informed that it intends to disclose the related decisions on April 19, 2017. On April 19, 2017, the Appellate Court upheld the appeals 
and determined that the suspension of payments proceedings of Oi Holanda and PTIF be converted into bankruptcy proceedings in the 
Netherlands. These decisions of the Dutch Appellate Court are restricted to its jurisdiction and the Dutch laws since Oi Holanda and 
PTIF have appealed against them with the Dutch Supreme Court on May 1, 2017. 

On May 30, 2017, the Dutch Trustee of Oi Holanda filed a lawsuit in the Netherlands against Oi Móvel and Oi requiring, in brief: (i) the 
annulment of the loans entered into by Oi Holanda/Oi and Oi Holanda/Oi Móvel; and, as a result, (ii) the sentencing of Oi and Oi Móvel 
to repaying the loans, and (iii) the sentencing of Oi and Oi Móvel to the payment of compensation for damages resulting on account of 
the alleged wrongdoing, to be determined and discussed in a special proceeding. 

On July 5, 2017, Oi Holanda filed an intervention request that was denied and which is now the subject of an appeal pending decision. 

On July 7, 2017, the Dutch Supreme Court overruled the appeals filed by PTIF and Oi Holanda and on May 1, 2017 the same court 
upheld  the  decisions  of  the  Dutch  Appellate  Court  that  the  proceedings  are  to  be  converted  into  bankruptcy  proceedings  in  the 
Netherlands. These Dutch Supreme Court decisions have no impact in Brazil while they are not ratified by the Superior Court of Justice 
(and the Company is not aware that a proceeding aimed at such ratification has been initiated) and other jurisdictions that acknowledge 
the competence of the Brazilian courts to process the Judicial Reorganization. 

27.     REORGANIZATION ITEMS, NET 

Transactions and events directly associated with the reorganization are required, under the guidance of ASC 852 Reorganizations, to be 
separately  disclosed  and  distinguished  from  those  of  the  ongoing  operations  of  the  business.  The  Company  used  the  classification 
“Reorganization items, net” on the consolidated statements of operations to reflect expenses, gains and losses that are the direct result of 
the reorganization of its business.

(a) These amounts are the result of the adjustment to record contingent liabilities to their allowed claim amount which is difference 

than their carrying amount prior to the RJ proceedings. 

(b) During  the  year  ended  December 31,  2017,  and  2016  the  Company  incurred  in  R$369 million  and  R$253 million  related  to 

professional advisors who are assisting with the bankruptcy process, respectively. 

28.     LIABILITIES SUBJECT TO COMPROMISE 

As a result of the judicial reorganization proceedings in Brazil and other international jurisdictions (which are considered to be similar 
in all substantive respects to Chapter 11) prepetition liabilities, as shown below were classified as subject to compromise based on the 
assessment of these obligations following the guidance of ASC 852 Reorganizations. Prepetition liabilities subject to compromise are 
required to be reported at the amount expected to be allowed as a claim by the Judicial Reorganization Court, regardless of whether they 
may be settled for lesser amounts and remain subject to future adjustments based on negotiated settlements with claimants, actions of 
the  Judicial  Reorganization  Court,  rejection  of  executory  contracts,  proofs  of  claims  or  other  events.  The  following  table  reflects 
prepetition liabilities subject to compromise as at December 31, 2017 and 2016:

(*) The total amount of prepetition liabilities subjected to compromise differs from the R$63,960,008 amount of the Creditors List 
prepared by the Company and filed on May 29, 2017. Per ASC 852, prepetition liabilities subject to compromise included the best 
estimate, as per the criteria set forth in ASC 450, of contingencies/claims subject to compromise and that in accordance with the 
Brazilian Law were not included in the Creditor’s List. 

Under the Judicial Reorganization proceedings, claims are classified in one of four classes and the treatment of claims under the JRP is 
differentiated for each of these classes: 

• Class I – labor-related claims; 

• Class II – secured claims; 

• Class III – unsecured claims, statutorily or generally privileged claims, and subordinated claims; and 

• Class IV – claims held by “small companies” under Brazilian law.

The following discussion briefly describes the material types of claims classified as “Liabilities subject to compromise,” describes the 
classification of those claims under the JRP and, the treatment of those claims under the JRP. 

Loans and Financing 

On a consolidated basis, the Euro-denominated indebtedness was R$19,578 million as of each of December 31, 2017 and 2016, the U.S. 
dollar-denominated indebtedness was R$16,978 million as of December 31, 2017 and 2016, and the real-denominated indebtedness was 
R$12,573 million as of December 31, 2017 and 2016. 

Under  the  instruments  governing  all  of  the  financial  indebtedness,  the  commencement  of  the  RJ  Proceedings  on  June 20,  2016 
constituted an event of default. As a result of the commencement of the RJ Proceedings, all principal and interest under each of these 
debt instruments was deemed immediately due and payable. As a result of the application of ASC 852 in preparing the consolidated 
financial  statements,  all  loans  and  financings  outstanding  as  of  June 20,  2016  have  been  classified  as  “Liabilities  subject  to 
compromise”  as  of  December 31,  2017  and  2016.  The  Company  did  not  recorded  interest  expenses  and/  or  exchange  currency 
fluctuations on the balances of these financial liabilities during 2017 or 2016. 

Principal loans and financings consist of: 

•

•

•

•

•

•

credit facilities with BNDES; 

fixed-rate notes issued in the international market; 

credit facilities with international export credit agencies; 

unsecured lines of credit obtained from Brazilian and international financial institutions; 

debentures issued in the Brazilian market; and 

real estate securitization transactions. 

The  following discussion  briefly  describes the claims recognized in  the RJ  proceedings  with respect  to loans and financings  and  the 
loans and financings under the JRP. 

Credit Facilities with BNDES 

As  of December 31, 2017 and 2016, the Company  had a  variety  of outstanding  credit  facilities with  BNDES. The proceeds of these 
credit  facilities  have  been  used  for  a  variety  of  purposes,  including  funding  of  investment  plans,  funding  the  expansion  of 
telecommunications plant (voice, data and video), and making operational improvements to meet the targets established in the General 
Plan on Universal Service Goals and the General Plan on Quality Goals in effect at the time of these loans. As of December 31, 2017 
and 2016, all debt instruments with BNDES were secured by pledges of certain limited amount of accounts receivable. 

The following table sets forth for certain information with respect to outstanding credit facilities with BNDES, including the aggregate 
amount of the claims under such credit facilities recognized by the RJ Court.

Under the JRP, the claim of BNDES under these credit facilities was classified as a Class II claim. Under the JRP, creditors holding 
Class II claims will be entitled to receive payment of 100% of the principal amount of their recognized claims in reais, adjusted by the 
interest/inflation adjustment rate. The principal amount of these claims will be paid in 108 monthly installments beginning in the 73rd
month  following  the  Brazilian  Confirmation  Date,  in  the  amount  of  0.33%  of  the  outstanding  principal  for  the  first  60  monthly 
installments,  1.67%  of  the  outstanding  principal  for  the  next  47  monthly  installments  and  the  remainder  at  maturity  on  the  15th
anniversary  of  the  Brazilian  Confirmation  Date.  The  principal  amount  of  these  claims  will  accrue  interest  at  the  TJLP  rate  plus 
2.946372%per annum from the Brazilian Confirmation Date. Interest will be capitalized to increase the principal balance under these 
claims  on  an  annual  basis  during  the  first  four  years  following  the  Brazilian  Confirmation  Date,  and  will  be  paid  monthly  in  cash 
thereafter through the final maturity.

As a result of payments made to some of the holders of the bonds issued by PTIF that participated in the Settlement Creditors Program 
in Portugal (Note 1), the total claims represented by these bonds has been reduced by R$136 million. 

Under  the  JRP,  the  claims  of  holders  of  these  bonds  were  classified  as  Class III  claims.  Under  the  JRP,  each  holder  of  beneficial 
interests in the bonds issued by the Company, Oi Holanda and PTIF, or Bondholders, is entitled to receive the Qualified Recovery (as 
described below), the Non-Qualified Recovery (as described below) or the general treatment provided for unsecured credits under the 
JRP, which is referred to as the Default Recovery, in respect of the claims evidenced by the bonds such Bondholder beneficially holds, 
which is the Company referred to as Bondholder Credits. 

Under the JRP, Bondholders that had individualized their Bondholder Credits in accordance with the procedures established in the JRP 
and by the RJ Court, which referred to as Eligible Bondholders, were permitted to make an election as to the form of recovery that they 
wish to receive. All other Bondholders are only entitled to receive the Default Recovery. 

Under the JRP, Eligible Bondholders with Bondholder Credits in excess of US$750,000 (or the equivalent in other currencies), which 
referred  to  as  Qualified  Holders,  were  entitled  to  elect  to  receive  either  the  Qualified  Recovery  or  the  Default  Recovery.  Eligible 
Bondholders  with  Bondholder  Credits  of  less  than  US$750,000  (or  the  equivalent  in  other  currencies),  which  referred  to  as 
Non-Qualified Holders, were entitled to elect to receive either the Non-Qualified Recovery or the Default Recovery. 

Under  the  JRP,  Eligible  Bondholders  were  entitled  to  make  an  election  of  the  form  of  their  recovery  during  an  election  period  that 
commenced on February 6, 2018 and ended on March 8, 2018. Holders that made valid recovery elections will be entitled to participate 
in  settlement  procedures  and  the  Company  expects  to  conduct  shortly  following  the  satisfaction  or  waiver  of  the  conditions  to  the 
issuance of the new common shares set forth in the JRP. 

Qualified Recovery 

Under the JRP, the Qualified Recovery with respect to each US1,000 of Bondholder Credits (or the equivalent in other currencies) will 
consist of: 

• US$195.61 aggregate principal amount of senior unsecured notes of the Company, or the New Notes;

The  Company  used  to  recognize  a  provision  for  the  risk  of  unfavorable  outcome  in  these  lawsuits  based  on  certain  legal  doctrine. 
During 2009, however, decisions issued by appellate courts led the Company to revisit the amount accrued and the risk classification of 
the relevant lawsuits. The Company, considering obviously the peculiarities of each decision and based on the assessment made by its 
legal department and outside legal counsel, changed its estimate on the likelihood of an unfavorable outcome from possible to probable. 
In 2009, the Company’s management, based on the opinions of its legal department and outside legal counsel, revised the measurement 
criteria  of  the  provision  for  contingencies  related  to  the  financial  interest  agreements.  Said  revision  contemplated  additional 
considerations regarding the dates and the arguments of the final and unappealable decisions on ongoing lawsuits, as well as the use of 
statistical  criteria  to  estimate  the  amount  of  the  provision  for  those  lawsuits.  The  Company  currently  accrues  these  amounts  mainly 
taking  into  consideration  (i) the  criteria  above,  (ii) the  number  of  ongoing  lawsuits  by  matter  discussed,  (iii) the  average  amount  of 
historical losses, broken down  by  matter  in dispute, and (iv) the impacts of  the payment  of these contingencies  in  the context  of  the 
Judicial  Reorganization  Plan  ratified  on  January 8,  2018.  In  addition  to  these  criteria,  in  2013  the  courts  recognized,  in  several 
decisions, the enforcement of the twenty-year statute of limitations for the lawsuits that met this criterion and the Company, based on 
the opinion of its in-house and outside legal counsel, understands that the likelihood of loss is remote. Therefore, it is not necessary to 
set up a provision. 

At the end of 2010, the website of the Superior Court of Justice (STJ) disclosed news that this court had set compensation criteria to be 
adopted by the Company to the benefit of the shareholders of the former CRT for those cases new shares, possibly due, could not be 
issued because of the sentence issued. According to this court judgment news, which does not correspond to a final decision, the criteria 
must be based on (i) the definition of the number of shares that each claimant would be entitled, measuring the capital invested at the 
book  value  of  the  share  reported  in  CRT’s  monthly  trial  balance  on  the  date  it  was  paid-in,  (ii) after  said  number  of  shares  is 
determined, it must be multiplied by its quotation on the stock exchange at the closing of the trading day the final and unappealable 
decision is issued, when the claimant becomes entitled to sell or disposed of the shares, and (iii) the result obtain must be adjusted for 
inflation (IPC/INPC) from the trading day of the date of the final and unappealable decision, plus legal interest since notification. In the 
case of succession, the benchmark amount will be the stock market price of the successor company. 

Based on current information, management believes that its estimate would not be materially impacted as at December 31, 2017. There 
may be, however, significant changes in the items above, mainly regarding the market price of Company shares. 

Small claims courts 

Claims  filed  by  customers  for  which  the  individual  indemnification  compensation  amounts  do  not  exceed  the  equivalent  of  forty 
(40) minimum wages; and 

The  Company  is  a  party  to  a  large  number  of  lawsuits  filed  in  small  claims  courts  and  calculates  the  related  provision  based  on  a 
statistical methodology that takes into consideration, but not limited to, the total number of existing lawsuits, the claims make in each 
lawsuit,  the  amount  claimed  in  each  lawsuit,  the  history  of  payments  made,  and  the  technical  opinion  of  the  legal  counsel  and  the 
impacts of the Judicial Reorganization Plan, issued on January 8, 2018.

Refer  to  several  of  ongoing  lawsuits  discussing  contract  terminations,  certain  agencies  requesting  the  reopening  of  customer  service 
centers, compensation claimed by former suppliers and building contractors, in lawsuits filed by equipment vendors against Company 
subsidiaries, revision of contractual terms and conditions due to changes introduced by a plan to stabilize the economy, and litigation 
mainly involving discussions on the breach of contracts. 

As a result of the commencement of the RJ Proceedings on June 20, 2016, all outstanding unsecured civil claims against the RJ Debtors 
as of that date became subject to compromise under the RJ Proceedings. As of December 31, 2017 and 2016, the aggregate amount of 
the  contingencies  for  civil  claims  (other  than  claims  of  ANATEL  and  other  regulatory  agencies)  recognized  by  the  RJ  Court  was 
R$2,929 million and R$3,096 million, respectively. 

Under  the  JRP,  unsecured  civil  claims  against  the  RJ  Debtors  were  classified  as  Class III  and  IV  claims.  Under  the  JRP,  if  judicial 
deposits have been made with respect to adjudicated civil claims, holders of these civil claims that expressly agree with the amounts of 
the civil claims acknowledged by the RJ Debtors, including those indicated in the Second List of Creditors, and waive the right to offer, 
propose, or proceed with credit actions, qualifications, divergences, objections, or any other measure (including appeals) which aim at 
increasing  the  amounts  of  their  civil  claims,  will  be  paid,  subject  to  the  reduction  of  the  amount  of  any  civil  claim  classified  as  a 
Class III  claim  as  described  below,  through  the  application  of  judicial  deposits  related  to  these  civil  claims  until  the  balance  of  the 
relevant judicial deposits has been exhausted. Any amount of a civil claim remaining unpaid after the application of the related judicial 
deposit will entitle the holder to a  recovery with respect to the balance of that civil claim  similar to the  Default  Recovery described 
above  in “ —Loans and  Financing—Fixed Rate Notes—Default Recovery.” Any amount of a civil  claim remaining unpaid after the 
application of the related judicial deposit will entitle the holder to a recovery with respect to the balance of that civil claim similar to the 
Default Recovery described above in “ —Loans and Financing—Fixed Rate Notes—Default Recovery.” In the event that the related 
judicial  deposit  is  greater  than  the  amount  that  the holder  of a  civil  claim  is entitled  to  withdraw,  the  RJ Debtors  will  be  entitled  to 
withdraw the difference from the judicial deposit. 

The  amount  of  the  claim  of  a  holder  of  civil  claims  (other  than  claims  of  ANATEL  and  other  regulatory  agencies)  that  have  been 
classified as Class III claims will be reduced based on the amount of such civil claims as follows: 

• Civil claims of more than R$1,000 and equal to or less than R$5,000 will be reduced by 15%; 

• Civil claims of more than R$5,000 and equal to or less than R$10,000 will be reduced by 20%; 

• Civil claims of more than R$10,000 and equal to or less than R$150,000 will be reduced by 30%; and 

• Civil claims of more than R$150,000 will be reduced by 50%.

Under the JRP, if judicial deposits have been made with respect to unadjudicated civil claims, following adjudication of their claims, 
the holders of these civil claims that expressly agree with the amounts of the civil claims acknowledged by the RJ Debtors, including 
those  indicated  in  the  Second  List  of  Creditors,  and  waive  the  right  to  offer,  propose,  or  proceed  with  credit  actions,  qualifications, 
divergences,  objections,  or  any  other  measure  (including  appeals)  which  aim  at  increasing  the  amounts  of  their  civil  claims,  will  be 
paid, subject to the reduction of the amount of any civil claim classified as a Class III claim as described above, through the application 
of judicial deposits related to these civil claims until the balance of the relevant judicial deposits has been exhausted. Any amount of a 
civil claim remaining unpaid after the application of the related judicial deposit will entitle the holder to a recovery with respect to the 
balance of that civil claim similar to the Default Recovery described above in “ —Loans and Financing—Fixed Rate Notes—Default 
Recovery.” Any amount of a civil claim remaining unpaid after the application of the related judicial deposit will entitle the holder to a 
recovery  with  respect  to  the  balance  of  that  civil  claim  similar  to  the  Default  Recovery  described  above  in  “  —Loans  and 
Financing—Fixed  Rate  Notes—Default  Recovery.”  In  the  event  that  the  related  judicial  deposit  is  greater  than  the  amount  that  the 
holder of a civil claim is entitled to withdraw, the RJ Debtors will be entitled to withdraw the difference from the judicial deposit. 

Contingencies liabilities (Note 18) 

The  Companies  under  judicial  reorganization  and  its  subsidiaries  are  also  parties  to  several  lawsuits  in  which  the  likelihood  of  an 
unfavorable outcome is classified as possible, in the opinion of their legal counsel, and for which no provision for contingent liabilities 
has been recognized. 

The breakdown of contingent liabilities with a possible unfavorable outcome and, therefore, not recognized in accounting, is as follows: 

Labor
Civil
Total

Trade Payables 

2017
796,471
950,208
1,746,679

2016
714,376
1,064,642
1,779,018

The  trade  payables  are  represented  by  the  suppliers  that  provide  services  related  to  the  infrastructure  services,  network  maintenance 
services, interconnection costs, rental and insurance, rights of way and other third-party services. 

As a result of the commencement of the RJ Proceedings on June 20, 2016, all outstanding trade payables as of that date became subject 
to compromise under the RJ Proceedings. As of December 31, 2017 and 2016, the aggregate amount of the claims of trade creditors 
recognized by the RJ Court was R$2,139 million and R$2,159 million, respectively. 

Under the JRP, the claims of trade creditors were classified as Class III or Class IV claims. Under the JRP, each of these trade creditors 
were  entitled  to  make  an  election  of  the  form  of  their  recovery  during  an  election  period  that  commenced  on  February 6,  2018  and 
ended on February 26, 2018. 

Trade creditors that, under the JRP, continued to supply goods and/or services to the RJ Debtors without any unreasonable change in the 
terms and conditions and that do not have any on-going litigation against any of the RJ Debtors, other than litigation related to the RJ 
Proceeding were deemed to be “Strategic Supplier Creditors” under the JRP. Strategic Supplier Creditors with claims of R$150,000 or 
less (or the equivalent in other currencies), other than claims arising from loans or other funding provided to Oi Holanda, were entitled 
to elect to receive 100% of their claims in cash within 20 business days after the end of the election period. Strategic Supplier Creditors 
with  claims  of  more  than  R$150,000  (or  the  equivalent  in  other  currencies),  other  than  claims  arising  from  loans  or  other  funding 
provided to Oi Holanda, were entitled to elect to receive R$150,000 (or the equivalent in other currencies) in cash within 20 business 
days after the end of the election period and 90% of their remaining claims in cash in four equal annual installments, plus interest on the 
amount of their claims at the rate of TR plus 0.5% per annum for claims denominated in reais, and at the rate of 0.5% per annum for 
claims denominated in U.S. dollars or euros.

Trade creditors that were not deemed to be “Strategic Supplier Creditors” under the JRP were entitled to elect to: 

•

•

•

receive the entire amount of their claim in cash in a single installment if the aggregate amount of their claims was less than 
or equal to R$1,000;

their  claim  under 

terms  similar 

Trade  creditors  that  did  not  elect  one  of  these  recovery  options  are  entitled  to  a  default  recovery  similar  to  the  Default  Recovery 
described in “ —Loans and Financing—Fixed Rate Notes—Default Recovery.” 

Pension Plans 

As a result of the commencement of the RJ Proceedings on June 20, 2016, the Company obligations to fund certain of post-retirement 
defined benefit plans as of that date became subject to compromise under the RJ Proceedings. As of each of December 31, 2017 and 
2016, the aggregate amount of unfunded obligations under the post-retirement defined benefit plans the contingencies recognized by the 
RJ Court was R$560 million, all of which related to claims of Fundação Atlântico. 

Under the JRP, obligations to fund the post-retirement defined benefit plans were classified as Class I claims. Claims due to Fundação 
Atlântico will be payable in six annual, equal installments, beginning on the fifth anniversary of the Brazilian Confirmation Date and 
the  amount due will  bear  interest at the  rate  of  the National  Consumer  Price  Index (INPC) plus  5.5%  per  annum from  the Brazilian 
Confirmation Date. Interest will be capitalized to increase the principal balance of these claims on an annual basis during the first five 
years following the Brazilian Confirmation Date, and will be paid annually in cash thereafter through the final maturity. 

29.     CONDENSED COMBINED AND CONSOLIDATED DEBTOR IN-POSSESSION FINANCIAL INFORMATION 

The financial statements below represent the condensed combined financial statements of the Debtors. The nonfiling entities are 
accounted for as nonconsolidated subsidiaries in these financial statements and, as such, their net loss is included using the equity 
method of accounting. Intercompany balances among the Debtors amounting to R$50,1 billion in 2017 (R$45,6 billion in 2016) 
related mainly with loans granted and have been eliminated in the financial statements presented below. Intercompany balances 
among the Debtors and the nonfiling entities have not been eliminated.

On March 1, 2018 Oi Internet was merged with and into Oi Móvel, both indirect subsidiaries of the Company, in compliance with the 
provisions  of  clauses  3.1.6  and  7.1  of  JRP.  In  addition,  the  merger  of  the  operations  of  Oi  Internet  and  Oi  Móvel,  through  the 
consolidation  of  the  activities  performed,  will  bring  administrative,  economic,  and  tax  benefits,  with  a  decrease  of  costs  and  the 
generation of synergy gains that will increase efficiency in the supply of services. 

Conclusion of Memorandum of Understanding – Oi S.A. and Tim S.A. 

On February 26, 2018, the Company entered into memorandum of understanding (MOU) with TIM Participações S.A. (“TIM”) which 
is  another  Telecom  Company  in  Brazil.  This  memorandum  begun  a  negotiation  aimed  at  solving  any  existing  disagreements  and 
initiates  a  new  infrastructure  sharing  planning  cycle,  in  line  with  the  partnerships  that  are  already  common  practice  in  the  Brazilian 
telecommunications  market.  This  initiative  strengthens  a  propositional  and  industrial  collaboration  environment  within  a  context  of 
healthy competition in the telecommunications industry. 

Judicial Reorganization 

On January 8, 2018, the Judicial Reorganization Court issued a decision that ratifies the JRP and grants the judicial reorganization to the 
Oi Companies. Said decision was published on February 5, 2018, initiating the period for the creditors of the RJ Debtors to elect one of 
the payment options to recover their claims, as provided for in the JRP, which ended on February 26, 2018, except for bondholders, 
whose deadline was extended to March 8, 2018, as decided by the Judicial Reorganization Court on February 26, 2018.
