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

On March 6, 2014,May 13, 2016, the exchange rate forreais into U.S. dollars was R$2.3093.504 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$3.905 to US$1.00 on December 31, 2015, R$2.656 to US$1.00 on December 31, 2014 and R$2.343 to US$1.00 on December 31, 2013, R$2.044 to US$1.00 on December 31, 2012, and R$1.876 to US$1.00 on December 31, 2011, in each case, as reported by the Brazilian Central Bank. The real/U.S. dollar exchange rate fluctuates widely, and the selling rate on March 6, 2014May 13, 2016 may not be indicative of future exchange rates. See “Item 3. Key Information—Exchange Rates” for information regarding exchange rates for thereal since January 1, 2009.2010.

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 fromreais into U.S. dollars using the selling rate as reported by the Brazilian Central Bank on December 31, 20132015 of R$2.3433.905 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 inreais. Our consolidated financial statements as of December 31, 20132015 and 20122014 and for the three years ended December 31, 20132015 are included in this annual report.

We prepare our consolidated financial statements in accordance with United States generally accepted accounting principles, or U.S. GAAP. Based on our operating cash flows and the impact such operating cash flows have had on our liquidity, in combination with the level of our indebtedness and the potential impact if we cannot satisfy certain financial covenants under our current debt instruments in 2016, our independent registered public accounting firm has included an emphasis paragraph related to the substantial doubt with respect to our ability to continue as a going concern in their report on our consolidated financial statements for the year ended December 31, 2015. However, our financial statements have been prepared assuming we will continue to operate as a going concern, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business.

We are also required to prepare financial statements in accordance with accounting practices adopted in Brazil, or Brazilian GAAP, which are based on:

 

Brazilian Law No. 6,404/76, as amended by Brazilian Law No. 9,457/97, Brazilian Law No. 10,303/01, and Brazilian Law No. 11,638/07, which we refer to collectively as the Brazilian Corporation Law;

 

  

the rules and regulations of the Brazilian Securities Commission (Comissão de Valores Mobiliários), or the CVM, and the Brazilian Federal Accounting Council (Conselho Federal de Contabilidade); and

 

  

the accounting standards issued by the Brazilian Accounting Pronouncements Committee (Comitê de Pronunciamentos Contábeis), or the CPC.

Brazilian GAAP differs in certain important respects from accounting principles generally accepted in the United States, or U.S. GAAP. Differences between Brazilian GAAP and U.S. GAAP where applicable to Oi are summarized in note 31 to our audited consolidated financial statements included in this annual report.

Corporate ReorganizationAcquisition and Disposition of PT Portugal

On February 27, 2012, Tele Norte Leste Participações S.A., or TNL, Telemar Norte Leste S.A.,May 5, 2014, we concluded a subsidiary of TNL, or Telemar, Coari Participações S.A., a wholly owned subsidiary of Telemar, or Coari, and Brasil Telecom S.A., a subsidiary of Coari, undertook a corporate reorganization in which:

Telemar and Coari engaged in a split-off (cisão) and merger of shares (incorporação de ações) under Brazilian law in which (1) Telemar transferred the shares of Coari that it owned to Coari, (2) Coari assumed a portion of the liabilities of Telemar, (3) the common and preferred shares of Telemar were exchanged for newly issued common and preferred shares of Coari, and (4) Telemar became a wholly-owned subsidiary of Coari;

Coari and Brasil Telecom engaged in a merger (incorporação) under Brazilian law in which Coari merged with and into Brasil Telecom,capital increase, which we refer to as the Coari merger;

TNL and Brasil Telecom engaged in a merger (incorporação) under Brazilian law in which TNL merged with and into Brasil Telecom, which we refer to as the TNL merger; and

the corporate name of Brasil Telecom was changed to Oi S.A., or Oi.

We refer to these transactions collectively as the corporate reorganization.

The following chart sets forth the ownership structure of TNL, Telemar and Coari in Brasil Telecom immediately prior to the corporate reorganization. The percentages in bold italics represent the percentage of the votingOi capital owned by the parent company of each entity, and the percentages not in bold italics represent the percentage of the total share capital owned by the parent company of each entity.

The following chart sets forth the structure of Brasil Telecom and Telemar immediately following the corporate reorganization.

LOGO

As a result of the corporate reorganization, we have consolidated the results of TNL into results as from February 28, 2012. We have accounted for the Coari merger and the TNL merger using the carry-over basis of our own assets and liabilities and of the assets and liabilities assumed of TNL, Telemar, and Coari as from the date of the reorganization. The carry-over basis of the assets and liabilities were determined at the lowest level entity in the group (i.e., the effects of the purchase accounting relating to Coari´s acquisition of Brasil Telecom (now Oi S.A.) will not be reflected in the assets and liabilities of Oi S.A. in its consolidated financial statements as a result of the TNL merger). Additionally, our historical financial statements have not been restated to reflect the impacts of the corporate reorganization on a retrospective basis. Our non-current intangible assets and property, plant and equipment are recorded on a different basis in our parent company´s consolidated financial statements, reflecting the amortized purchase price allocated to these assets resulting from Coari´s acquisition of our company on January 8, 2009. For more details regarding the corporate reorganization, see “Item 4. Information on the Company—Our History and Development—Corporate Reorganization of TNL, Telemar and Our Company.”

Information regarding Oi in this annual report is presented giving effect to the corporate reorganization on February 27, 2012. However, financial and other data included in this annual report regarding Oi and its consolidated subsidiaries as of December 31, 2011 and earlier dates and for periods ended on December 31, 2011 and earlier dates is historical in nature and does not give pro forma effect to the corporate reorganization, except as otherwise noted.

In addition, financial and other data included in this annual report regarding TNL and its consolidated subsidiaries as of December 31, 2011 and earlier dates and for periods ended on December 31, 2011 and earlier

dates is historical in nature and includes financial and other data regarding Brasil Telecom, a subsidiary of TNL prior to February 27, 2012. The financial statements of TNL as of and for the year ended December 31, 2011 have not been presented elsewhere in this annual report and have not been filed with the SEC.

Proposed Business Combination

On October 1, 2013, we entered into a memorandum of understanding, or the Memorandum of Understanding, with Portugal Telecom, AG Telecom Participações S.A., or AG Telecom, LF Tel S.A., or LF Tel, PASA Participações S.A., or PASA, EDSP75 Participações S.A., or EDSP, Bratel Brasil S.A., or Bratel Brasil, Avistar, SGPS, S.A., or BES, and Nivalis Holding B.V., or Ongoing,increase, in which we and they agreed to the principles governing a seriesissued (1) 121,674,063 of transactions, including the business combination described below.

The business combination transaction involves three principal components:

a capital increase of our company in which we expect to issue common shares and 280,483,641 of our preferred shares in an underwritten offering for an aggregate amount of at least R$7,0008,250 million in cash, and (2) 104,580,393 of our common shares and 172,025,273 of our preferred shares to Portugal TelecomPharol in exchange for the contribution by Portugal TelecomPharol to our company of all of the shares of its subsidiary PT Portugal. PT Portugal which will at that time will own (a)provides a broad range of telecommunications services in Portugal and owned significant interests in telecommunications companies in Angola, Cape Verde, Namibia, and São Tomé and Principe in Africa and Timor-Leste in Asia.

On June 2, 2015, we sold all of the operating assetsshare capital of PT Portugal Telecom, except interests held directly or indirectlyto 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 Oithe event that the consolidated revenues of PT Portugal and Contax Holding, and (b) all of Portugal Telecom’s liabilities at the timeits subsidiaries (as of the contribution, which we referclosing date) for any single year between the year ending December 31, 2015 and the year ending December 31, 2019 is equal to collectively as the Oi capital increase;or exceeds €2,750 million.

a merger of shares (incorporação de ações) under Brazilian law, a Brazilian transaction in which, subject to the approvals of the holders of voting shares of our company and TmarPart, all of the shares of our company not owned by TmarPart will be exchanged for TmarPart common shares and we will become a wholly-owned subsidiary of TmarPart, which we refer to as the merger of shares; and

a merger (incorporação) under Portuguese and Brazilian law, of Portugal Telecom with and into TmarPart, with TmarPart as the surviving company in which the shareholders of Portugal Telecom will receive an aggregate number of TmarPart shares equal to the number of TmarPart shares held by Portugal Telecom immediately prior to the merger, which we refer to as the merger.

In connection with the business combination,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. As of December 31, 2015, we expect that:

TmarPart will enter into several additional transactions designed to recapitalize TmarPart so that at the timehad used R$8,682 million of the merger of shares, TmarPart will have no net debt;

TmarPart and our company will enter into merger transactions in order to simplify the ownership structure of TmarPart;

The shares of TmarPart will be listed on the Novo Mercado segmentcash proceeds of the BM&FBOVESPA and onPT Portugal Disposition for the NYSE Euronext Lisbon, and ADSs representing the sharesprepayment of TmarPart will be listed on the NYSE; and

The shareholders agreements among the shareholders of TmarPart will be terminated.

We believe that the business combination will:

permit the formation of a single large multinational telecommunications company based in Brazil with more than 100 million customers in seven countries with a total population of approximately 260 million people;

maintain the continuity of operations under the trademarks of Oi and Portugal Telecom in their respective regions of operation, subject to unified control and management by TmarPart;

further consolidate the operationsindebtedness of our company, and Portugal Telecom, with the goal of achieving

v


significant economies of scale, maximizing operational synergies, reducing operational risks, optimizing efficient investments and adopting best operational practices;

strengthen the capital structure of TmarPart, facilitating its access to capital and financial resources;

consolidate the shareholder bases of our company, Portugal Telecom and TmarPart as holders of a single class of common shares or ADSs traded on the Novo Mercado segment of the BM&FBOVESPA, the NYSE and NYSE Euronext Lisbon;

diffuse TmarPart’s shareholder base, as a resultdate of which no shareholder or group of shareholders will hold a majority interest in TmarPart’s capital;

result in the adoption by TmarPart of the corporate governance practices of the Novo Mercado segment of the BM&FBOVESPA; and

promote greater liquidity of the TmarPart common shares than currently is available to holders of our shares and Portugal Telecom’s shares.

For more information on the proposed business combination and related transactions, see “Item 4. Information on the Company—Our History and Development—Proposed Business Combination.”

Share Split

On April 10, 2007, we authorized the reverse split of all of our issued common shares and preferred shares into one share for each 1,000 issued shares. This reverse share split became effective on May 14, 2007. In connection with this reverse share split, we authorized a change in the ratio of our Preferred ADS. Upon the effectiveness of our reverse share split and the ratio change, the ratio of our preferred shares to our Preferred ADSs, changed from 3,000 preferred shares per Preferred ADS to three preferred shares per Preferred ADS. All references to numbers of shares and dividend amounts in this annual report have used an additional R$5,350 million of these net cash proceeds for the prepayment and repayment of indebtedness of our company. We expect to use the remainder of these net cash proceeds for the repayment of indebtedness of our company.

In anticipation of the PT Portugal Disposition, PT Portugal transferred Portugal Telecom International Finance B.V., or PTIF, its wholly-owned finance subsidiary, to Oi. As a result of the completion of the PT Portugal Disposition, the indebtedness of PTIF, which had previously been adjustedclassified 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 give effect toOi all of the 1,000-for-one reverseoutstanding share split.capital of PT Participações, SGPS, S.A., or PT Participações, which holds:

iii


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

Share Splits

On August 15, 2012, we changed the ratio applicable to our Preferred ADS from three preferred shares per Preferred ADS to one preferred sharesshare per Preferred ADS. All references to numbers of Preferred ADSs in this annual report have been adjusted to give effect to this change in ratio.

On November 18, 2014, our shareholders acting in an extraordinary general shareholders meeting authorized (1) the reverse split of all of our issued common shares into one common share for each 10 issued common shares, and (2) the reverse split of all of our 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 our Common ADSs or Preferred ADSs in connection with this reverse share split; each Common ADS continues to represent one of our common shares and each Preferred ADS continues to represent one of our preferred shares. All references to numbers of shares of our company, dividend amounts of our company and earnings per share of our company 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 our 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 the Brazilian federal telecommunications regulator (Agência Nacional de Telecomunicações), or 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.

Exchange Rates

The Brazilian foreign exchange system allows the purchase and sale of foreign currency and the international transfer ofreais 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 thereal to float freely or will intervene in the exchange rate market through the return of a currency band system or otherwise. Thereal 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.”

Risk Factors

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.

General Risks Relating to the Brazilian Telecommunications Industry and Our Company

Our fixed-line telecommunications services face increased competition from mobile services providers, other fixed-line service providers and cable television service providers, which may adversely affect our revenues and margins.

Our fixed-line telecommunications services in Region I (which consists of 16 Brazil states located in the northeastern and part of the northern and southeastern regions) and Region II (which consists of the Federal District and nine Brazilian states located in the western, central and southern regions) face increasing competition from mobile services as the prices for mobile services decline and approach those of fixed-line services. Based on information available from ANATEL, from December 31, 2010 to April 30, 2013 (the latest date for which such information is available from ANATEL), the number of fixed lines in service in Brazil increased from 42.0 million to 44.5 million. We expect (1) the number of fixed lines in service in Regions I and II to experience slow growth, as certain 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 substitute calls on mobile phones in place of fixed-line calls as a result of promotional mobile rates (such as free calls within a mobile provider’s network). The rate at which the number of fixed lines in service in Brazil may decline depends on many factors beyond our control, such as economic, social, technological and other developments in Brazil. In addition, new fixed lines that we install are expected to be less profitable than existing ones because new fixed-line customers generally have lower average incomes than our existing customers, subscribe to our lower cost service plans and generate fewer chargeable minutes of usage. For the year ended December 31, 2013, our traditional local fixed-line telecommunications services represented 29.4% of our net operating revenue. Because we derive a significant portion of our net operating revenue from our traditional local fixed-line telecommunications services, 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.

We also compete in the market for local fixed-line services with other fixed-line service providers, primarily with Empresa Brasileira de Telecomunicações – Embratel, or Embratel, and GVT S.A., or GVT. In addition to direct competition for corporate customers Embratel competes with us for residential customers in Regions I and II with services that it provides using the cable infrastructure of its subsidiary, Net Serviços de Comunicação S.A., or Net. Net is a cable television company that is our main competitor in the broadband services market. Embratel is a subsidiary of América Móvil S.A.B. de C.V., or América Móvil, one of the leading telecommunications service providers in Latin America. Under an agreement entered into between Embratel and Net in November 2005, Net offers integrated voice, broadband and pay television services to the Brazilian residential market through a single network infrastructure. In addition, we compete in each of these service regions with smaller companies that have been authorized by ANATEL to provide local fixed-line services. Embratel, GVT and Net 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 loss of a significant number of fixed-line customers would adversely affect our net operating revenue and may adversely affect our results of operations. For a detailed description of our competition in the local fixed-line services market, see “Item 4. Information on the Company—Competition—Local Fixed-Line Services.”

Our mobile services face strong competition from other mobile services providers, which may adversely affect our revenues.

The mobile services market in Brazil is extremely competitive. We face competition from large competitors such as TIM Participações S.A., or TIM, Telefônica Brasil S.A., or Telefônica Brasil, which markets its mobile

services under the brand name “Vivo,” and Claro S.A., or Claro. As of November 30, 2013, based on information regarding the total number of subscribers as of that date available from ANATEL we had a market share of 18.6% of the total number of subscribers in Brazil, ranking behind Telefônica Brasil with 28.7%, TIM with 27.0% and Claro with 25.2%, and we captured 10.7% of all net additions of mobile subscribers in Brazil (calculated based on the number of mobile subscribers at the end of a period less the number of mobile subscribers at the beginning of that period) during 2013. Telefônica Brasil, TIM and Claro 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 mobile services business depends on our ability to increase and retain our customer base. Each additional customer subscribing to our service 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 mobile services business. During 2013, our average customer churn rate in the mobile services segment, representing the number of subscribers whose service was disconnected during each month, whether voluntarily or involuntarily, divided by the number of subscribers at the beginning of such month, was 4.2% per month.

We have experienced increased pressure to reduce our rates in response to pricing competition. This pricing competition often takes the form of special promotional packages, which may include, among other things, mobile handset subsidies, traffic usage promotions and incentives for calls made within a mobile services provider’s own network. 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 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 a detailed description of our competition in the mobile services market, see “Item 4. Information on the Company—Competition—Mobile Services.”

Our long-distance services 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 is highly competitive. Our principal competitors for long-distance services are TIM and Embratel, which are currently offering long-distance services throughout Brazil at rates that are charged on a per call, rather than per minute, basis. We compete with Telefônica Brasil, which is the incumbent fixed-line service provider in Region III. Increased competition from long-distance service providers has resulted in pressure on our long-distance rates and adversely affected our revenue from these services. In addition, the proliferation of new types of service plans, such “same network” subscription plans that offer unlimited long distance calls and data combination plans are impacting the long-distance services market in Brazil. Competition in the 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 domestic market has had and could continue to have a material adverse effect on our revenues and margins. See “Item 4. Information on the Company—Competition—Long-Distance Services.”

Data transmission services are not subject to significant regulatory restrictions and, as a result, we face an increasing amount of competition in this business.

Competition in data transmission services is not subject to significant regulatory restrictions and, therefore, the market is open to a large number of competitors. Some competitors, such as cable operators, offer telephone and broadband services, which do not require them to use our fixed-line network, thereby allowing them to reach our customers without paying interconnection fees to our company. Increasing competition in data transmission services may lead to rate reductions in this segment, adversely affecting the net operating revenue that we generate from this business. Additionally, increased competition for data transmission customers may require us to increase our marketing expenses and our capital expenditures and may lead to the loss of broadband customers, in each case leading to a decrease in our profitability. For a detailed description of our competition in the data transmission services market, see “Item 4. Information on the Company—Competition—Data Transmission Services.”

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. For example, we have made significant investments in the last three years in connection with the implementation of our UMTS (Universal Mobile Telecommunications System), or 3G, services, and we have begun investingare making investments in the implementation of our LTE (Long Term Evolution), or 4G, services. In addition, we believe that in the medium-term, personal mobility service providers in Brazil will experience 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 will become 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 such as WhatsApp, Viber and Skype. Since November 2011, we have deployed a network of Wi-Fi hotspots in indoor public and commercial sites, outdoor public spaces and residential access points. 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 operations are dependent upon our networks. A system failure could cause delays or interruptions of service, which could cause us to suffer losses.

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.

The mobile telecommunications industry and participants in this industry, including us, may be harmed by reports suggesting that radio frequency emissions cause 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. On June 29, 2015, ANATEL commenced a public consultation regarding its proposed Regulatory Agenda for the 2015-2016 cycle, which, among other items, provides for the reevaluation of regulations regarding human exposure to radiofrequency electromagnetic fields. Although we believe these regulations have not had a material impact on the business of our company to date, the Brazilian government or ANATEL may enact new laws or regulations regarding electromagnetic emissions and exposure that could have an adverse effect on our business.

Risks Relating to Our Company

We have a substantial amount of debt, which could restrict our financing and operating flexibility and have other adverse consequences.

As of December 31, 2015, we had R$59,857 million aggregate principal amount of outstanding debt. We are subject to certain financial covenants under the instruments that govern some of 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.

Furthermore, some of our debt instruments include financial covenants that require Oi or Telemar to maintain certain specified financial ratios. Prior to December 31, 2015, we executed temporary modifications of each of our debt instruments that contain covenants requiring Oi to maintain specified levels of consolidated debt to consolidated EBITDA (other than the debt instruments governing Oi’s 5th and 9th issuances of debentures), pursuant to which Oi was required to maintain a consolidated net debt to consolidated EBITDA ratio, determined based on our financial statements prepared in accordance with Brazilian GAAP, of no more than 6.0 to 1.0 as of December 31, 2015. Most of these temporary modifications continue to require Oi to maintain a consolidated net debt to consolidated EBITDA ratio of no more than 6.0 to 1.0 for each of the fiscal quarters of 2016. Upon the expiration of these temporary modifications, the consolidated debt to EBITDA ratio that Oi is required to maintain under each of these debt instruments will be reduced to their pre-existing levels, the most restrictive of which will require that Oi maintain a consolidated debt to EBITDA ratio of less than 4.0 to 1.0. Under each of these debt instruments, the creditor has the right to accelerate the debt if, at the end of any applicable period we are not in compliance with the defined financial covenants ratios. We have repaid the principal amount outstanding under Oi’s 5th and 9th issuances of debentures in the aggregate amount of R$23 million.

Our debt facilities with BNDES contained a number of financial covenants (including ratios with respect to shareholders equity to total assets and consolidated debt to EBITDA) that were measured on a semi-annual basis on June 30 and December 31. Under these debt facilities, noncompliance with two or more of these covenants in one semi-annual period would automatically trigger the right of BNDES to retain proceeds (in an amount equivalent to three times our next amortization payment under each debt facility with BNDES) from receivables otherwise payable to us in reserve accounts pledged for the benefit of BNDES until such time as the breach is cured.

On June 30, 2015, we were not in compliance with the covenants in each of our debt facilities with BNDES that require Oi to maintain a shareholder’s equity to EBITDA ratio of at least 0.25 to 1 and a consolidated debt to EBITDA ratio of less than 4.0 to 1. As a result, BNDES, had the right to retain proceeds from receivables in reserve accounts pledged for the benefit of BNDES, as described above. In November, 2015, we and BNDES amended the terms of each of our debt facilities with BNDES. As a result of these amendments, (1) the consolidated debt to consolidated EBITDA ratio, determined based on our financial statements prepared in accordance with Brazilian GAAP, that Oi was required to maintain was increased to 6.0 to 1.0 for the December 31, 2015 measurement date, (2) the measurement period under each of these debt facilities was reduced to quarterly periods, and (3) BNDES has the right to accelerate the debt under each of these debt facilities, at the end of any applicable period, we are not in compliance with two or more of the financial covenants contained in these debt facilities.

We were in compliance with each of the financial covenants applicable the debt instruments to which Oi and its subsidiaries are a party as of December 31, 2015 (other than the debt instruments governing Oi’s 5th and 9th issuances of debentures). We are seeking waivers from those creditors for which these temporary modifications do not cover all measurement periods to and including the periods ending on December 31, 2016. We cannot provide investors with any assurance that these waivers will be obtained. In the event that we are unable to obtain waivers of the anticipated breaches of these covenants in these debt instruments, or identify and implement financial and strategic alternatives to optimize our liquidity and debt profile, we may be unable to meet our obligations under these debt instruments in the event that the creditors under these debt instruments seek to enforce their available remedies.

Under the Trust Deed governing each of the Bonds issued by PTIF (other than the PTIF 6.25% Notes due 2016), or the PTIF Bonds, we were required to file audited financial statements of PTIF as of and for the year ended December 31, 2014 with the Dutch Chamber of Commerce no later than January 31, 2016. On April 29, 2016, Citicorp Trustee Company Limited, the trustee under this Trust Deed, or the PTIF Trustee, delivered a written notice to PTIF and Oi noting that the failure of PTIF to provide the 2014 audited financial statements constituted a potential event of default under the PTIF Bonds and requesting the delivery of those financial statements. PTIF is continuing to work with its auditor to complete the preparation of its 2014 audited financial statements as soon as possible.

The PTIF Trustee has notified PTIF that if PTIF fails to deliver the financial statements on or prior to May 29, 2016 and the PTIF Trustee determines that this failure is materially prejudicial to the interests of the holders of the PTIF Bonds, the PTIF Trustee could declare that the PTIF Bonds are immediately due and repayable. Under the terms of the PTIF Bonds, the PTIF Trustee is not obliged to exercise its discretion to declare any PTIF Bonds immediately due and repayable or to take any other action to enforce the rights of the holders of the PTIF Bonds unless it shall have been indemnified to its satisfaction and specifically directed or requested to do so by a requisite percentage of the holders of the PTIF Bonds in accordance with the terms and conditions of the PTIF Bonds.

The instruments governing a substantial portion of our indebtedness contain cross-acceleration clauses and the occurrence of an event of default under one of these instruments, could trigger an event of default under other indebtedness or enable the creditors under other indebtedness to accelerate that indebtedness or those obligations. Were a substantial amount of our outstanding indebtedness to be accelerated, we may not have sufficient funds to repay such debt when due.

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.

On March 9, 2016, we announced that we had 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 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, as an initial step towards discussions of a potential restructuring of its indebtedness.

For more information regarding the debt instruments of our company and our indebtedness as of December 31, see “Item 5. Operating and Financial Review and Prospects—Liquidity and Capital Resources.”

Our independent registered public accounting firm has indicated that our financial condition raises substantial doubt as to our ability to continue as a going concern.

Based on our operating cash flows and the impact such operating cash flows have had on our liquidity, in combination with the level of our indebtedness and the potential impact if we cannot satisfy certain financial covenants under our current debt instruments in 2016, our independent registered public accounting firm has included an emphasis paragraph related to the substantial doubt with respect to our ability to continue as a going concern in their report on our consolidated financial statements for the year ended December 31, 2015. However, our financial statements have been prepared assuming we will continue to operate as a going concern, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. If we become unable to continue as a going concern, we may seek the protection of the courts through ajudicially supervised reorganization (recuperação judicial) proceeding in Brazil or liquidate our assets, and the values we receive for our assets in liquidation or dissolution could be significantly lower than the values reflected in our consolidated financial statements. The reaction of investors and others to the inclusion of a going concern statement by our auditors, our operating cash flows and questions regarding our potential inability to continue as a going concern may cause others to choose not to deal with us due to concerns about our ability to meet our contractual obligations and may materially adversely affect our share price and our ability to continue to execute our business plans, raise new capital and/or make our scheduled debt payments on a timely basis or at all.

Because our cash flows from operating activities are negative, and are expected to continue to be negative through 2016, we will likely need to meet our obligations and fund our working capital with cash on hand and proceeds from existing amounts available under our financing facilities.

Our cash flows from operations were negative in 2015, and based on our current plans, we expect our cash flows from operating activities to remain negative through 2016. Our current projections are based on a number of key assumptions relating to, among other things, attainment of traffic volume targets, customer base, launching of

bundled products attractive to customers, service sales prices, foreign exchange fluctuation and the success of the efforts to identify and implement financial and strategic alternatives to optimize the liquidity and debt profile. If any of our assumptions are not borne out or are otherwise not correct, our cash flows from operations could be significantly lower than expected. As a result, our cash flows from operating activities could continue to be negative and our capital expenditures and debt service obligations could exceed our cash flows from operations beyond 2016 and for an extended period of time. There can be no assurance that we will succeed in executing on our plans or that we will generate positive cash flows from operations or cash flows from operations sufficient to cover our capital expenditures and debt service obligations in the future.

We plan to maintain a significant level of capital expenditures in order to continue to pursue our business plans. Additionally, based on our current level of debt, we are obligated to make payments of cash interest and principal in the aggregate amount of R$15,282 million during 2016. In addition, we need to pay cash taxes and fund our working capital.

Because of the combined impact of our recent and projected results of operations, our non-investment grade credit rating, the inclusion of the going concern statement in the report of our independent registered public accounting firm, restrictions in our current debt and/or general conditions in the financial and credit markets, our access to the capital markets is likely to be limited or nonexistent. As a result, we will need to meet our obligations and fund our working capital with cash on hand and proceeds from existing amounts available under our financing facilities. We may not be able to meet our obligations or other means for any significant period of time, and as a result, if we are unable to successfully restructure our debt on terms satisfactory to our company, we may not be able to execute our business plan or meet our obligations. If we become unable to meet our obligations, we may seek the protection of the courts through a judicially supervised reorganization (recuperação judicial) proceeding in Brazil.

Any downgrade in the ratings of our company or our debt securities would likely result in increased interest and other financial expenses related to our borrowings and debt securities and could reduce our liquidity.

Standard & Poor’s Ratings Services, a division of The McGraw-Hill Companies, Inc., or Standard & Poor’s, Moody’s Investors Service, or Moody’s, and Fitch, Inc., or Fitch, maintain ratings of our company and our debt securities. Currently, Standard & Poor’s, Moody’s and Fitch maintain ratings of our company on a local and a global basis. On a global basis, Standard & Poor’s maintains a foreign currency rating for our company of “CCC-,” Moody’s maintains a foreign currency rating for our company of “Caa1,” and Fitch maintains a foreign currency rating for our company of “CCC.” Our export credit facility guaranteed by Exportkreditnämnden, or EKN, contained a requirement that we prepay all outstanding amounts in the event that our credit rating was downgraded below Ba2 by Moody’s or BB by Fitch. As a result of the actions by these rating agencies, we were required to prepay the outstanding principal amount under this export credit agreement of R$202 million in April 2016. Any decision by these agencies to downgrade the ratings of our company or of our debt securities in the future would likely result in increased interest and other financial expenses relating to our borrowings and debt securities and the inclusion of financial covenants in the instruments governing new indebtedness, and could significantly reduce our ability to obtain such financing on satisfactory terms or in amounts required by us.

We rely on strategic suppliers of equipment, materials and 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, materials and services, including Nokia Solutions and Networks do Brasil Telecomunicações Ltda., or Nokia Solutions, Huawei do Brasil Telecomunicações Ltda., or Huawei, Ericsson Telecomunicações S.A., or Ericsson, and A.R.M. Engenharia Ltda., or A.R.M. Engenharia, to provide us with equipment, materials and services that we need in order to expand and to operate our business in Brazil. 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 extensive and geographically widespread 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 service 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.

As a result of our financial condition, suppliers of the equipment, materials and services necessary for our operations and expansion may require further assurances from us in order to continue doing business with us.

We believe that our suppliers may take our financial condition, particularly to the extent that it is perceived to impact our ability to continue to make timely payments to them, into account when deciding whether to continue or begin providing equipment and services to us. During 2015, our operating cash flows have been negatively affected by a number of factors. If suppliers or potential suppliers who are aware of our deteriorating financial situation become concerned that we will be unable to continue to perform under our agreements or make timely payments, they may require advance payments, financial guarantees or other assurances before they provide equipment, materials or services to us or may refuse to provide equipment, materials or services to us at all. If suppliers were to do so, our ability to expand and maintain our networks or operate our business may be impaired, which could have an adverse effect on our financial condition or results of operations.

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 of December 31, 2015, we had provisioned R$4,435 million for probable losses relating to various tax, labor and civil legal and administrative proceedings against us. As of December 31, 2015, we had claims against us of R$24,048 million in tax proceedings, R$780 million in labor proceedings and R$1,238 million in civil proceedings with a risk of loss classified as “possible” for which we had made no provisions.

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.”

The minority shareholder of Africatel has asserted that our acquisition of PT Portugal triggered its right to require us to purchase its shares of Africatel under the Africatel shareholders’ agreement. If we are required to purchase this interest in Africatel, it will divert resources that could otherwise be deployed to reduce indebtedness or make investments under our business plan. If any such purchase is funded through our incurrence of additional debt, there would be a material adverse effect on our consolidated leverage.

We indirectly own 75% of the share capital of Africatel. Samba Luxco S.à.r.l., an affiliate of Helios Investors L.P., or Samba Luxco, owns the remaining 25%. Africatel holds all of our interests in telecommunications companies in sub-Saharan Africa, including our interests in Unitel, Cabo Verde Telecom, S.A. in Cape Verde, Mobile Telecommunications Limited in Namibia, and CST Companhia Santomense de Telecomunicações S.A.R.L. in São Tomé and Príncipe, among others. Pharol, our subsidiaries Africatel GmbH & Co. KG, or Africatel GmbH, and PT Ventures SGPS S.A., or PT Ventures, and Samba Luxco are parties to a shareholders’

agreement, which we refer to as the Africatel shareholders’ agreement.

On September 16, 2014, our subsidiary, Africatel GmbH, which directly holds our interest in Africatel, received a letter from Samba Luxco in which 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 the letter, Samba Luxco purported to exercise the alleged put right and thereby require Africatel GmbH to acquire its shares in Africatel.

On September 26, 2014, Africatel GmbH responded to Samba Luxco stating that there had not been any action or event that would trigger the right to exercise the put option under the Africatel’s shareholders’ agreement and that Africatel GmbH intended to challenge Samba Luxco’s purported exercise of the put option. On the same date, we issued a Material Fact disclosing Samba Luxco’s purported exercise of the put option, our understanding that the exercise of the put option is not applicable, and that our board of directors had authorized our management to take the necessary actions to sell our interest in Africatel.

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 other rights and claims allegedly arising out of Oi’s acquisition of PT Portugal. Africatel GmbH presented its answer to Samba Luxco’s request for arbitration on December 15, 2014. The arbitral tribunal was constituted on March 12, 2015 and the proceedings are ongoing. Africatel GmbH intends to continue to vigorously defend these proceedings.

If we were to acquire the interest of Samba Luxco in Africatel as a result of the exercise of Samba Luxco’s purported put right under the Africatel shareholders’ agreement, our acquisition of this interest would reduce the resources that would be available to us to reduce our outstanding indebtedness or pursue other investment opportunities. If any such purchase were to be funded through our incurrence of additional debt, the consolidated leverage of our company could increase materially, which could have a material adverse effect on our financial condition and results of operations.

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 that we entered into with Pharol under which we transferred defaulted commercial paper of Rio Forte to Pharol in exchange for the delivery to our company of common shares and preferred shares of our company as described under “Item 4. Information on the Company—Our Recent History and Development—Rio Forte Defaults and PT Exchange,” we agreed to indemnify Pharol against any loss arising from Pharol’s contingent or absolute tax or anti-trust obligations in relation to the assets contributed to our company in the Oi Capital Increase described under “Item 5. Operating and Financial Review and Prospects—Overview—Oi Capital Increase and Acquisition of PT Portugal,” and from 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 Exchange Agreement.

In the 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 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 2015, we recorded provisions for doubtful accounts in the amount of R$721 million, or 2.6% of our net operating revenue, primarily due to subscribers’ delinquencies. As of December 31, 2015, our provision for doubtful accounts was R$561 million.

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.

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, 2015, our Brazilian pension benefit plans had an aggregate deficit of R$544 million. 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.”

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 Empresa Brasileira de Telecomunicações – Embratel (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 Embratel, and GVT S.A. (a subsidiary of Telefônica Brasil S.A., or Telefônica Brasil, the largest telecommunications operator in Brazil), or GVT;

other broadband service providers, including Net Serviços de Comunicação S.A., or Net (a subsidiary of América Móvil, our primary competitor in the broadband services market); Companhia Paranense de Energia – Copel, or Copel, and Companhia Energética de Minas Gerais – CEMIG, or Cemig Telecom, which provide fiber optic infrastructure; and smaller regional broadband service providers; and

other Pay-TV service providers, including our primary competitor SKY Brasil Serviços Ltda., or SKY, and Net.

Based on information available from ANATEL, from December 31, 2012 to December 31, 2015, the number of fixed lines in service (including the number fixed lines provided to our SME and Corporate Services customers) in our service areas (all of Brazil other than the state of São Paulo) declined from 27.7 million to 27.2 million. As of December 31, 2015, based on information available from ANATEL, (1) we had a market share of 56.4% of the total fixed lines in service in Region I of Brazil and a market share of 52.9% of the total fixed lines in service in Region II of Brazil (in each case, including the fixed lines provided to our SME and Corporate Services customers); (2) Embratel had a market share of 25.3% of the total fixed lines in service in Region I and a market share of 18.4% of the total fixed lines in service in Region II; and (3) GVT had a market share of 9.9% of the total fixed lines in service in Region I and a market share of 23.4% 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. 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 Embratel and Telefônica Brasil, which have market shares of 32.5% and 28.7% for broadband services in Brazil, respectively, according to data from ANATEL. As of January 2016, we had a market share of 25.1% for broadband services in Brazil, according to data from ANATEL. Embratel provides local fixed-line services to residential customers through Net’s cable network in the portions of Regions I and II where Net provides cable television service. Telefônica Brasil provides local fixed-line services through its own network and through its subsidiary GVT’s network. The primary drivers of competition in the broadband industry are speed and price, with discounts typically offered in the form of bundled services. Net 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 América Móvil, which provides DTH service through Embratel under the “Claro TV” brand and Pay-TV services using coaxial cable through Net. 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, Embratel 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 detailed description of 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) Telefônica Brasil, which markets its mobile services under the brand name “Vivo,” and (3) Claro S.A., a subsidiary of América Móvil, or Claro. As of December 31, 2015, based on information regarding the total number of subscribers as of that date available from ANATEL, we had a market share of 18.6% of the total number of mobile subscribers (including subscribers in our SME and Corporate Services), ranking behind Telefônica Brasil with 28.4%, TIM with 25.7% and Claro with 25.6%. Telefônica Brasil, TIM and Claro 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 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 3G and 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 the year ended December 31, 2015, the average customer churn rate in our Personal Mobility Services business, representing the number of subscribers whose service was disconnected during each month, whether voluntarily or involuntarily, divided by the number of subscribers at the beginning of such month, was 12.4%.

We have experienced increased pressure to reduce our mobile rates in response to pricing competition. This pricing competition often takes the form of special promotional packages, which may include, among other things, mobile handset subsidies and 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 result 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 a detailed description of our competition in the personal mobility services market in Brazil, see “Item 4: Information on the Company—Competition—Personal Mobility Services.”

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

Our SME and Corporate 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, and corporate customers, as well as interconnection, network usage and traffic transportation services to other telecommunications providers. 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 SME and Corporate Services business, the loss of a significant number of SME or corporate customers would adversely affect our net operating revenue and may adversely affect our results of operations. For a detailed description of our competition in the business and corporate market in Brazil, see “Item 4: Information on the Company—Operations in Brazil—Competition—SME and Corporate 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 in laws and regulations may adversely impact our business.

OurThe 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 example, in July 2014 ANATEL has proposed new regulationsapproved rules under which itinterconnection rates charged by our company for the use of our fixed-line and mobile networks would modifybe reduced over a period of years until they were set at rates based on a long-run incremental cost methodology. As a result, the productivity discount factor, or Factor X, applicable to the determinationmobile interconnection rates for Regions I, II and III declined by 25% each in February 2014, 33.3% each in February 2015 and 40.0%, 35.2% and 27.6%, respectively, in February 2016, with additional cuts approved through 2019. In addition, ANATEL approved cuts for most of rate increases available to public concessionaires providing fixed-line services.our fixed interconnection rates ranging from 9.1% and 20.0% in February 2016, with additional cuts approved through 2019. These regulations were submitted for public consultation in July 2011 and the public consultation period ended on September 1, 2011. We expect these new regulations, as they may be modified as a result of ANATEL’s further analysis, to be adopted in 2014. We cannot predict when these regulations will be adopted or whether they will be adopted as proposed. Some of these regulations, if adopted, may 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 or financial position.operations.

We cannot predict whether ANATEL, the Brazilian Ministry of Communications (Ministério das Comunicações) or the Brazilian government will adopt other telecommunications sector policies in the future or the consequences of such policies on our business andor the business of our competitors.

Our local fixed-line and domestic long-distance concession agreements in Brazil are subject to periodic modifications by ANATEL and expirewe cannot assure you that the modifications to these concession agreements will not have adverse effects on December 31, 2025. Our bids for new concessions upon the expiration of our existing concessions may not be successful.company.

We provide fixed-line telecommunications services in Regions I and IIour Brazilian service areas pursuant to concession agreements with the Brazilian government. OurThese 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 yearfive-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 theour concession agreements may be subject to revision in connection with each future amendment. 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. We submitted our comments during this period. 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 Ministry of Communications created a working group, consisting of three members from each of ANATEL and the Ministry of Communications, to evaluate the status of the concessions and propose guidelines for the amendment of the concession agreements. In November 2015, the Ministry of Communications opened public consultation on the new regulatory framework for telecommunications. The Ministry of Communications has extended the deadline for contributions on multiple occasions. In April 2016, the Ministry of Communications, based on the working group’s findings, issued a decree addressing guidelines for the establishment of a new regulatory framework for telecommunications, which will be implemented by ANATEL through the conclusion of the concession amendments. 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. As a result of the publication of these guidelines, ANATEL requested a further postponement of the review of our concession agreements, which was granted. As a result of this extension, the review of our concession agreements is currently scheduled to occur by December 2016.

We cannot assure you that any future amendments to our concession agreements, including the amendments now expected to be made in 2016, 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 term 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 Regions I and II.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 itsour quality and universal service obligations. See “Item 4.4: Information on the Company—Regulation of the Brazilian Telecommunications Industry—Regulation of Fixed-Line Services.”

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 the 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, among others. As of December 31, 2013,2015, we had recorded provisions in the amount of R$1,0451,149 million in connection with fines sought to be imposed by ANATEL.ANATEL, including fines which we are contesting through judicial proceedings. In the event that we are unsuccessful in obtaining final approval of the inclusion of the R$5 billion of fines and claims we have proposed to be included in the Terms of Adjustment of Conduct (“Termos de Ajuste de Conduta”) program, or the TAC program, we could be required to constitute an additional provision of the portion of these fines and claims for which we have not previously established a provision. Additional fines from ANATEL, the establishment of an additional provision or fines in excess of the provisioned amount could adversely impact our financial condition and results of operations. See “Item 4. Information on the Company—Regulation of the Brazilian Telecommunications Industry” and “Item 8. Financial Information—Legal Proceedings—Civil Claims—Claims Relating to Oi S.A. and Our Brazilian Operations—Administrative Proceedings.”

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. For example, on July 23, 2012, ANATEL temporarily suspended our ability to accept new customers for our mobile services in the States of Amazonas, Amapá, Mato Grosso do Sul, Roraima and Rio Grande do Sul due to ANATEL’s perception of our failure to meet capital investment and quality of service commitments in those states. This suspension lasted for approximately two weeks until we were able to propose new quality of service goals to ANATEL. See “Item 4. Information on the Company—Regulation of the Brazilian Telecommunications Industry—Regulation of Mobile Services—Obligations of Personal Mobile Services Providers.”

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.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; and

 

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.

We rely on strategic suppliers of equipment, materialsRisks Relating to Our African and 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.Asian Operations

We rely on few strategic suppliers of equipment, materials and services, including Nokia Solutions and Networks do Brasil Telecomunicações Ltda., or Nokia Solutions, Alcatel-Lucent Brasil S.A., or Alcatel-Lucent, Telemont Engenharia de Telecomunicações S.A., or Telemont, A.R.M. Engenharia Ltda., or A.R.M. Engenharia, and Huawei do Brasil Telecomunicações Ltda., or Huawei, to provide us with equipment, materials and services that we need in order to expand and to operate our business. 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 extensive and geographically widespread 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 service 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.

Our controlling shareholder, TmarPart, has control over us and TmarPart’s interests may not be aligned with your interests.

We are controlled by TmarPart which, as of March 6, 2014 directly and indirectly held 56.4% of our outstanding voting shares, excluding treasury shares but including TmarPart’s direct ownership and indirect ownership through its subsidiary Valverde Participações S.A. or Valverde. TmarPart’s shareholders are parties to four shareholders’ agreements governing their equity interests in TmarPart. See “Item 7. Major Shareholders and Related Party Transactions—Major Shareholders—TmarPart Shareholders’ Agreements.” TmarPart is entitled to appoint a majority of the members of our board of directors, and it has the power to determine the decisions to be taken at our shareholders’ meetings on matters of our management that require the prior authorization of our shareholders, including in respect of related party transactions, corporate restructurings and the date of payment of dividends and other capital distributions. The decisions of TmarPart on these matters may be contrary to the expectations or preferences of holders of our securities, including holders of our common shares, preferred shares and ADSs.

In order to expand our business, we may take advantage of the consolidation of the telecommunications industry through the acquisition of other telecommunications companies, which could adversely affect our business, results of operations and financial condition.

We may acquire other companies in the telecommunications industry as part of our growth and convergence strategy. A growth strategy that involves acquisitions may present certain risks to our business, results of operations and financial condition, such as:

difficulties in capturing synergies in the integration process, causing the anticipated benefits of the acquisition to be more limited than originally expected;

costs associated with any unforeseen antitrust restrictions;

failure to identify contingencies during the due diligence process;

uncertainty in relation to regulatory approval; and

distractions from our core business to pursue these acquisitions and implement the integration of acquired businesses.

If acquisition transactions cause us to incur unforeseen costs due to the factors described above, we may have to dedicate more resources than we had originally planned and eventually face substantial losses that would adversely affect our business, results of operations and financial condition.

Even if we identify suitable acquisition targets, we may be unable to complete acquisitions or obtain necessary financing to do so on satisfactory terms. Paying for acquisitions could require us to incur or assume debt and/or contingent liabilities, amortize certain identifiable intangible assets and incur acquisition-related expenses. In addition, we may be unable to realize all or any of the anticipated benefits from acquisitions or expansion in other related businesses because of operational factors or difficulties in integrating the acquisitions or such other related businesses with our existing businesses, including disparate information technology systems, database systems and business processes.

We have a substantial amount of existing debt, which could restrict our financing and operating flexibility and have other adverse consequences.

As of December 31, 2013, we had total debt of R$35,854 million. We are subject to certain financial covenants that limit our ability to incur additional debt. Our existing level of indebtedness and the requirements and limitations imposed by our 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.

Furthermore, some of our debt instruments include financial covenants that require us to maintain certain specified financial ratios. Additionally, the instruments governing a substantial portion of our indebtedness contain cross-default or cross-acceleration clauses and the occurrence of an event of default under one of these instruments could trigger an event of default under other indebtedness or enable the creditors under other indebtedness to accelerate that indebtedness.

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, cash required to serve our existing indebtedness reduces the amount available to us to make capital expenditures. If our growth in net operating revenue slows or declines in a significant manner, for any reason, we may not be able to continue servicing our debt. 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, seek additional equity capital or sell assets. We may be unable to obtain financing or sell assets on satisfactory terms,dispose of our interest in Africatel for a consideration that exceeds its carrying value in our financial statements or at all. For

more information regardingAny impairment of the debt instruments of our company and our indebtedness as of December 31, 2013, see “Item 5. Operating and Financial Review and Prospects—Liquidity and Capital Resources.”

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 of December 31, 2013, we had provisioned R$5,616 million for probable losses relating to various tax, labor and civil legal and administrative proceedings against us. As of December 31, 2013, we had claims against us of R$17,996 million in tax proceedings, R$877 million in labor proceedings and R$1,038 million in civil proceedings with a risk of loss classified as “possible” forfair market value at which we had made no provisions.

We are not required to disclose or record provisions for proceedingsour indirect investment in whichUnitel in 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 usstatements 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 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.

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. As a result, as of December 31, 2014 and 2015, we recorded the assets and liabilities of Africatel 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. We are subjecthave engaged a financial advisor to potential liabilitiesassist us with marketing and selling our interest in Africatel.

As of December 31, 2015, we recorded in our consolidated financial statements as assets held for sale R$7,686 million relating to our third-party service providers. Such potentialinterest in Africatel and TPT, including R$2,042 million of accrued dividends owed to our company by Unitel and R$3,436 million 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$745 million relating to our interest in Africatel and TPT. We are currently engaged in negotiations with the other shareholders of Unitel to seek alternatives for the realization of the value of our investment in Unitel.

We may involve claims by employeesnot be able to sell our interest in Africatel for consideration that exceeds the book value of third-party service providers directly against usour interest in Africatel, or at all. 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. For the year ended December 31, 2015, we recorded a R$408 million loss as if we werea result of our review of the direct employerfair value of such employees, as well as claims against us for secondary liability for, among other things, occupational hazards, wage parity or overtime pay,our investment 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 haveUnitel. Any further impairment of our indirect investment in Unitel may result in a material adverse effect on our business, financial condition and operating results.

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 may have been declared with respect to 2014 or may be declared with respect to succeeding fiscal years.

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, 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 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 or 2013.

On March 25, 2014, Unitel issued a statement claiming that PT Ventures is not listed on the shareholders’ register of Unitel, and that the board of directors of Unitel had notified Pharol about the existence of an irregularity, which purportedly resulted in Unitel being unable to distribute dividends to PT Ventures until the resolution of this irregularity. On June 3, 2014, the Angolan National Foreign Investment Agency endorsed the updating of PT Ventures’ name (formerly Portugal Telecom Internacional, SGPS, S.A.) in its Foreign Investment Certificate, confirming the current corporate name of the PT Ventures and thus remedying the irregularity alleged by Unitel’s board of directors.

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. As a result, PT Ventures has filed a suit against Unitel with an Angolan court seeking to nullify and cancel all actions purportedly taken by the May 13, 2015 shareholders’ meeting. PT Ventures has received a draft of the minutes of this meeting but has not received the final version. The draft minutes 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). Because we have not received fully executed minutes of this meeting, and because we are seeking to annul the actions taken by this meeting, we have not recorded our share of these dividends in our financial statements.

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, PT Ventures has filed a suit against Unitel with an Angolan court seeking to collect its share of the dividends declared by Unitel in 2010, 2011, 2012 and 2013, together with interest thereon. As a result of our institution of this suit, in 2015 we recognized a provision with respect to the unpaid dividends of US$132.2 million (R$516.2 million).

We cannot assure you that we will be successful in this suit, 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 with respect to fiscal year 2013 or may have been declared with respect to fiscal year 2014 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 started by PT Ventures on October 13, 2015, but then withdrew that counterclaim. 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.

PT Ventures is seeking to consolidate this arbitration proceeding with the separate arbitration proceeding brought by PT Ventures against the other shareholders of Unitel. We are subjectintend to delinquenciesdefend against the allegation by

Unitel’s other shareholders vigorously. If a binding decision by the arbitral tribunal were rendered ruling in favor of our accounts receivables. Ifthe interpretation of the Unitel shareholders’ agreement proposed by the other Unitel shareholder, PT Ventures could be required to sell its interest in Unitel for a value significantly lower than the amount that we are unable to limit payment delinquencies by our customers, or if delinquent payments by our customers increase,record in our financial condition and resultsstatements with respect to our indirect investment in Unitel. The sale 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 2013, we recorded provisions for doubtful accountsPT Ventures’ interest in the amount of R$850 million, or 3.0% of our net operating revenue, primarily due to subscribers’ delinquencies. As of December 31, 2013, our provision for doubtful accounts was R$654 million.

ANATEL regulations prevent us from implementing certain policies thatUnitel in these circumstances could have the effect of reducing delinquency, such as service restrictions or limitationsa material adverse impact on the types of services provided based on a subscriber’s credit record. If we are unable to successfully implement policies to limit subscriber delinquencies 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, depreciation of thereal, 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.

Our operations dependThe 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 our abilityUnitel’s board of directors was reduced to maintain, upgradea single director in June 2006, and operate efficiently our accounting, billing, customer service, information technologythe chief executive officer of Unitel has not been PT Ventures’ appointee since June 2006.

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 management information systemsthe 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 relyelect 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 systemsUnitel board of directors.

On October 13, 2015, PT Ventures initiated an arbitration proceeding against the other carriersshareholders 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. Vidatel Ltd., one of the other shareholders, presented its answer to PT Ventures’ request for arbitration on January 8, 2016. The arbitral tribunal was constituted on April 14, 2016 and the proceedings are ongoing.

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. of €178.9 million (R$760.4 million) and US$35.0 million (R$136.7 million) under co-billing agreements.a “Facility Agreement” entered into between Unitel and Unitel International Holdings B.V., or Unitel Holdings. Unitel Holdings is controlled by Mrs. Isabel dos Santos, an indirect shareholder of Unitel and a member of the board of directors of Unitel. PT Ventures abstained when the consolidated financial statements of Unitel that included these transactions were approved by the other Unitel shareholders at a shareholders meeting.

SophisticatedIn addition, Unitel has recognized the payment of a management fee of US$155.7 million (R$608.0 million) payable to a third-party in its individual financial statements for the year ended December 31, 2013 prepared in accordance with Angolan GAAP.

In September and November 2015, PT Ventures commenced litigation in the British Virgin Island and the Netherlands against Unitel Holdings and other entities concerning the related party transactions with Unitel.

Despite requests, PT Ventures has been unable to obtain documents and other information concerning transactions between Unitel and processing systems are vitalUnitel International Holdings B.V., including any transactions that Unitel may have entered into in addition to our growththose described above from 2012 and our ability2013. We have evidence that Unitel made additional loans to monitor costs, render monthly invoices for services, process customer orders, provide customer servicerelated parties in 2013 that were not approved in accordance with the terms of the Unitel shareholders’ agreement. We have not been able to obtain information with regard to the existence of similar transactions conducted in 2014 and achieve operating efficiencies. 2015.

We cannot assure you that we will be able to operate successfully and upgrade our accounting, information and processing systems orprevent Unitel from taking actions 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 to include in our invoices the long-distance services rendered by these providers, and they 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 network 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 operations are dependent upon our networks. A system failure could cause delays or interruptions of service, which could cause us to suffer losses.

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 gross 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.

The mobile telecommunications industry and participants in this industry, including us, may be harmed by reports suggesting that radio frequency emissions cause health problems and interfere with medical devices.

Media and other entities frequently suggest 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. ANATEL may enact new laws or regulations regarding electromagnetic emissions and exposure may be adopted that could have an adverse effect on our business.

Our commitment to meet the obligations of our 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, 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 and guaranteed future benefits to our current employees at the time of their retirement. As of December 31, 2013, our pension benefit plans had an aggregate deficit of R$643.6 million. 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. For a more detailed description of our pension plans, see “Item 6. Directors, Senior Management and Employees—Employees—Employee Benefits—Pension Benefit Plans.”

Risks Relating to the Proposed Business Combination

The increase in our share capital and the report on the value of PT Portugal, both of which are conditions to our acquisition of PT Portugal, have not been approved by the shareholders of our company, andshould require the approval of the shareholders of Portugal Telecommembers of the report on the value of PT Portugal, which is a condition to Portugal Telecom’s obligation to contribute the shares of PT Portugal to our company, has not been obtained.

Under Brazilian law, prior to our acquisition of PT Portugal, the holders of our voting share capital must (1) approve the proposal to amend our authorized capital limit in order that we will have sufficient authorized shares to complete the Oi capital increase, (2) ratify the engagement of Banco Santander (Brasil) S.A., or Santander Brasil, to prepare the valuation report concerning the shares of PT Portugal that we will acquire in the Oi capital increase, (3) approve the valuation report prepared by Santander Brasil on the shares of PT Portugal that we will acquire in the Oi capital increase, which we refer to as the PT Assets Valuation Report, and (4) approve the proposed value of the shares of PT Portugal that Portugal Telecom will contribute to our company as payment for shares to be issued to Portugal Telecom in the Oi capital increase. We have called a meeting of our shareholders to be held on March 27, 2014 to consider these matters. Approval of these matters will require the affirmative vote of holders representing a majority of our common shares present or represented at this meeting. On January 8, 2014, the technical body of the CVM (theSuperintendência de Relações com Empresas) issued an official opinion stating that the controlling shareholders of our company cannot vote with respect to the approval of the valuation of the shares of PT Portugal in the meeting of our shareholders called to consider these matters. We have appealed this decision to the full board of the CVM. If this appeal is successful, we have been advised that holders of our controlling shareholders intend to vote in favor of the approval of the valuation of the shares of PT Portugal. However, we can offer no assurances that the CVM will rule favorably on this appeal or that the CVM will rule of the appeal prior to the date of the shareholders meeting. Any decision by the CVM may be challenged by our company, our controlling shareholders or our minority shareholders in Brazilian courts. In addition, we can offer no assurances that if the CVM does not rule favorably on this appeal prior to the date of the shareholders meeting, the approval of the PT Assets Valuation Report will be obtained from our shareholders. The failure of our shareholders to approve the matters to be considered at this meeting would prevent our completion of the Oi capital increase.

Under the subscription agreement that we entered into with Portugal Telecom on February 19, 2014, or the PT subscription agreement, Portugal Telecom’s obligation to contribute the shares of PT Portugal to our company is subject to the satisfaction of several conditions, including the approval of the PT Assets Valuation Report by the shareholders of Portugal Telecom. Portugal Telecom has called a meeting of its shareholders to be held on March 27, 2014 to consider this matter. Approval of the PT Assets Valuation Report will require the affirmative vote of holders representing a majority of Portugal Telecom’s ordinary shares present or represented at this meeting. We can offer no assurances that the approval of the valuation of the shares of PT Portugal will be obtained from Portugal Telecom’s shareholders. The failure of Portugal Telecom’s shareholders to approve the valuation of the shares of PT Portugal at this meeting would prevent our completion of the Oi capital increase.

The Oi capital increase may not be successful and as a result, we may not meet certain conditions to Portugal Telecom’s obligation to contribute the shares of PT Portugal to our company.

Under the subscription agreement that we entered into with Portugal Telecom on February 19, 2014, or the PT subscription agreement, Portugal Telecom’s obligation to contribute the shares of PT Portugal to our company is subject to the satisfaction of several conditions, including (1) our obtaining proceeds in the cash portion of the Oi capital increase of at least R$7.0 billion, including proceeds of at least R$2.0 billion through the sale of share capital to Caravelas Fundo de Investimento em Ações, an investment fund managed by Banco BTG Pactual S.A., or Caravelas, and the shareholders of TmarPart, and (2) the settlement of the Oi capital increase on or prior to May 2, 2014. In the event that any of the conditions to Portugal Telecom’s obligation to contribute the shares of PT Portugal to our company, are not satisfied or waived by October 1, 2014, Portugal Telecom may, in its sole discretion, rescind the PT subscription agreement. In addition, Portugal Telecom has the right to terminate the PT subscription agreement if, after the bookbuilding process in the Oi capital increase, Portugal Telecom is expected to hold an interest of less than 36.6% of the share capital of TmarPart following the completion of the merger of shares, and we have the right to terminate the PT subscription agreement if, after the bookbuilding process in the Oi capital increase, Portugal Telecom is expected to hold an interest of more than 39.6% of the share capital of TmarPart following the completion of the merger of shares. As of the date of this annual report, we have not entered into any agreement with any underwriters of our shares which would obligate them to purchase shares in the Oi capital increase and our registrations with the CVM and the SEC of shares to be offered to the public in the Oi capital increase are not effective. The success of the Oi capital increase when commenced and the price of our shares in the Oi capital increase will depend in substantial part on factors outside of our control, including market conditions and investor demand for our shares. We can offer no assurances that the Oi capital increase will meet the conditions to Portugal Telecom’s obligation to contribute the shares of PT Portugal to our company or that the termination rights of our company or Portugal Telecom will not be triggered as a result of the bookbuilding process in the Oi capital increase, or that these rights, if triggered will be waived.

The merger of shares has not been approved by the boards of directors or shareholders of our company or TmarPart.

Under Brazilian law, prior to the submission of the merger of shares to the shareholders of our company and TmarPart, the boards of directors of our company and TmarPart must approve the merger of shares and the Protocol of Merger of Shares and Instrument of Justification (Protocolo e Justificação de Incorporação de Ações) between TmarPart and our company, which we refer to as the Oi merger agreement. Following the approval of the merger of shares and the Oi merger agreement by the boards of directors of our company and TmarPart, the merger of shares and the Oi merger agreement will be submitted to extraordinary general shareholders meetings of our company and TmarPart. Approval of the merger of shares will require (1) the affirmative vote of holders representing a majority of the number of issued and outstanding TmarPart common shares present or represented at a duly convened extraordinary general shareholders’ meeting, and (2) the affirmative vote of holders representing a majority of the total number of issued our common shares. We expect that ourUnitel board of directors will approvenominated by PT Ventures, including approving related party transactions with the merger of shares and the Oi merger agreement at a meeting to be convened shortly after the completion of the global offering and we understand that TmarPart’s board of directors will approve the merger of shares and the Oi merger agreement at a meeting to be convened on the same date. However, we can offer no assurances that these approvals will be obtained. In addition, we have been advised that holders of a sufficient number of shares of our company and TmarPart intend to vote in favor of the merger of shares at the extraordinary general shareholders meetings of our companies to approve the merger of shares. However, we can offer no assurances that these approvals will be obtained.

The merger has not been approved by the boards of directors orother shareholders of TmarPart or Portugal Telecom.

Under Brazilian and Portuguese law, priorUnitel that we believe are detrimental to the submission of the merger to the shareholders of TmarPart and Portugal Telecom, the boards of directors of TmarPart and Portugal Telecom must approve the merger and the Protocol of Merger and Instrument of Justification (Protocolo e Justificação de Incorporação) between TmarPart and Portugal Telecom, which we refer to as the PT merger agreement. Following the approval of the merger and the PT merger agreement by the boards of directors of TmarPart and Portugal Telecom, the merger and the PT merger agreement will be submitted to extraordinary general shareholders meetings of TmarPart and Portugal Telecom. Approval of the merger will require (1) the affirmative vote of holders representing a majority of the number of issued and outstanding TmarPart common shares present or represented at a duly convened extraordinary general shareholders’ meeting, and (2) the affirmative vote of holders representing two-thirds of the total number of outstanding Portugal Telecom ordinary shares and A shares at an extraordinary general shareholders’ meeting duly

convened on first call. We understand that the boards of directors of TmarPart and Portugal Telecom will approve the merger and the PT merger agreement at a meeting to be convened shortly after the completion of the global offering. However, we can offer no assurances that these approvals will be obtained. In addition, we have been advised that holders of a sufficient number of shares of TmarPart intend to vote in favor of the merger at the extraordinary general shareholders meeting of TmarPart to approve the merger. However, we can offer no assurances that this approval will be obtained. Finally, we can offer no assurances that the shareholders of Portugal Telecom will approve the merger.

ANATEL may impose significant obligations on TmarPart as conditions to its approval of the merger, and compliance with these obligations could materially and adversely affect the business, financial condition and results of operations of TmarPart followingUnitel. The use of the merger.

Under Brazilian regulations, the merger must be submitted to ANATEL to assess its effectsresources of Unitel in this manner could have a material adverse impact on the Brazilian telecommunications services market and to confirm whether the applicable requirements will be met. TmarPart submitted the merger to ANATEL on December 12, 2013. If ANATEL takes any action to impose conditions or performance commitments on TmarPart as part of the approval process for the merger, including conditions that would require TmarPart to undertake significant capital expenditures or would require us to divest any significant part of our assets, that action could materially and adversely affect the business, financial conditionposition and results of operations of TmarPart followingUnitel and therefore the merger and prevent TmarPart from achievingvalue of our investment in Unitel.

On October 13, 2015, PT Ventures initiated an arbitration proceeding against the anticipated benefitsother shareholders of Unitel as a result of the merger.

In addition, under the PT subscription agreement, Portugal Telecom’s obligation to contribute the sharesviolation by those shareholders of PT Portugal to our company is subject to the approval by ANATEL. We can offer no assurances that ANATEL will grant approvala variety of provisions of the mergerUnitel shareholders’ agreement, including the provisions that would have entitled PT Ventures to veto these related party transactions.

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 itspro 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 specifiedon which payment would be due. PT Ventures has filed a suit in the conditionAngolan court to the PT subscription agreement, or at all. If ANATEL does not grant approval of the merger on a timely basis, we can offer no assurances that Portugal Telecom will waive this condition to its obligation to contribute the shares of PT Portugal to our company.

The Portuguese Competition Authority may prohibit the merger if it determines that the merger is capable of significantly impeding effective competition in the Portuguese market.

The merger is subject to clearance by the Portuguese Competition Authority, and may only be completed after such clearance is obtained following a non-opposition decision (express or tacit). Portugal Telecom submitted a formal filing to the Portuguese Competition Authority on January 23, 2014. The Portuguese Competition Authority may prohibit the merger if it determines that the merger is capable of significantly impeding effective competition in the Portuguese market.

In connection with the Portuguese antitrust review, the Portuguese Competition Authority may ask ANACOM to issue a non-binding opinion on the possible impact of the merger on the Portuguese electronic communications markets in which Portugal Telecom operates. In response to this request, ANACOM may suggest remedies to be adopted by the Portuguese Competition Authority to address effects that ANACOM considers may adversely affect consumers or competition in the Portuguese electronic communications markets.

Additionally, as Portugal Telecom is an active participant in the Portuguese television distribution market, the Portuguese Competition Authority may request an opinion from the Portuguese Media Regulation Authority (Entidade Reguladora para a Comunicação Social), or ERC, in connection with the Portuguese antitrust review.

We can offer no assurances that the Portuguese Competition Authority will not prohibit the merger or will not impose additional conditions toannul the approval of the merger.Unitel capital increase at this shareholders’ meeting.

InThe agenda of this general shareholders meeting of Unitel included amendments to Unitel’s by-laws and purported amendments to Unitel shareholders’ agreement, in addition underto other matters that may have been raised at the PT subscription agreement, Portugal Telecom’s obligationshareholders’ meeting itself, which included investments by Unitel in Zimbabwe and a study in order to contributeimplement a corporate reorganization of Unitel. We have not been provided of the sharesdetails of PT Portugal to our company is subjectthe proposed by-law amendments nor of any purported amendments to the approval by the Portuguese Competition Authority of the merger. We can offer no assurances that the Portuguese Competition Authority will grant approval of the merger priorUnitel shareholders’ agreement. The December 15, 2014 meeting was suspended without any action taken on these items. PT Ventures has filed a suit in Angolan court to the date specified in the condition to the PT subscription agreement, or at all. If the Portuguese Competition Authority does not grant approval of the merger on a timely basis, we can offer no assurances that Portugal Telecom will waiveannul all resolutions taken during this condition to its obligation to contribute the shares of PT Portugal to our company.

If Portugal Telecom fails to obtain all required consents, approvals and waivers, third parties may terminate or alter existing contracts.

Third parties hold pre-emption rights in certain licenses and assets of Portugal Telecom and such rights may be exercisable in connection with the business combination. Portugal Telecom is also a party to joint ventures, license agreements and other agreements and instruments, some of which contain change of control provisions that may be triggered by the business combination. In addition, other agreements of Portugal Telecom may require the payment of fees in connection with a change of control transaction. If Portugal Telecom is unable to obtain any necessary waiver or consent, the operation of change of control provisions or the exercise of pre-emption rights may cause the loss of significant contractual rights and benefits, the termination of joint venture agreements and licensing agreements or may require the renegotiation of financing agreements and/or the payment of significant fees. We cannot assure investors that we will be able to negotiate new agreements on terms as favorable to it as those that Portugal Telecom had, or at all.

Under the PT subscription agreement, Portugal Telecom’s obligation to contribute the shares of PT Portugal to our company is subject togeneral shareholders meeting, including the approval of creditorsinvestments by Unitel in Zimbabwe and a study in order to implement a corporate reorganization of Portugal Telecom, where necessaryUnitel.

We cannot assess the impact to completeUnitel or our company of the business combination, including waiversmatters considered at the December 15, 2014 general shareholders’ meeting of creditorsUnitel or the proposed amendments to Unitel’s by-laws and purported amendments to the Unitel shareholders’ agreement as we have not been provided with sufficient details to appropriately analyze these matters. We note that there appears to be no legal authority for the other shareholders of Portugal Telecom.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.

Unitel’s concession to operate in Angola has expired and has not yet been renewed.

Unitel’s concession to provide mobile telecommunications services in Angola expired in April 2012. We can offer nocannot provide you with any assurances that Portugal Telecom will be able to obtain these approvals orregarding the terms under which Portugal Telecom will obtain these approvals. If Portugal Telecom is unablethe Angolan National Institute of Telecommunications (Instituto Angolano das Comunicações), or INACOM, would grant a renewal of this concession, if at all. A failure of Unitel to obtain these approvals, our ability to complete the business combination will be substantially impaired. In addition, if Portugal Telecom enters into agreements to obtain these approvals that impose material obligations on our company following the contributiona renewal of the shares of PT Portugal to our company or the merger, such additional obligationsthis concession could have a material adverse effect on our resultsthe ability of operations or financial position.

The implementation of the business combination may face significant challenges, and the ultimate advantages expectedUnitel to be derived  from this transaction will continue to be subject to a number of factors that are beyond our control.

The implementation of the business combination may present significant challenges, including unanticipated costs and delays, shareholder or creditor opposition, regulatory interference and excessive diversion of the attention of the management of our company, TmarPart and Portugal Telecom from the day-to-day management of our or their respective operating activities. If the senior management of our company, TmarPart and Portugal Telecom are unable to efficiently implement the business combination, the businesses of our company, TmarPart and Portugal Telecom could suffer. We cannot guarantee that the management of our company, TmarPart and Portugal Telecom will successfully or cost-effectively implement the business combination.

The business combination may not resultprovide mobile telecommunications services in the benefits that we, TmarPart and Portugal Telecom seek to achieve.

The ultimate advantages that we expect to derive from the business combination, such as the achievement of economies of scale, the maximization of operational synergies, the reduction of operational risks, the optimization of efficient investments, the adoption of best operational practices, the increased liquidity for our shareholders and the shareholders of Portugal Telecom and the diversification of the shareholder bases of our company, TmarPart and Portugal Telecom, will depend upon, among other factors, the future performance of the combined company, market conditions, investor interest in the securities of the combined company, the retention of key employees, the successful integration of the companies, and general economic, political and business conditions in Brazil, Portugal and other countries inAngola, which we and Portugal Telecom operate. The integration of our company, TmarPart and Portugal Telecom will be a complex, costly and time-consuming process. We cannot guarantee that the benefits that we, TmarPart and Portugal Telecom seek to achieve through the business combination will be realized. Any failure to integrate the companies or achieve the synergies and other benefits of the business combination could cause significant operating inefficiencies and affect the profitability of TmarPart and the market value of TmarPart common shares and ADSs.

Following the completion of the Oi capital increase, we will be subject to the risks inherent in the operations of PT Portugal and we may not have identified all of these risks.

Portugal Telecom is a reporting company under the Exchange Act and files periodic reports with the SEC. See “Item 10. Additional Information—Documents on Display” for information on how to obtain reports filed with the SEC. We make no representations with respect to, or assume any responsibility for the accuracy or completeness of the information contained in Portugal Telecom’s filings with the SEC. We have entered into the PT subscription agreement largely on the basis of publicly available information regarding Portugal Telecom and the valuation of the shares of PT Portugal prepared by Santander Brasil. We have had limited access to additional information regarding the assets and businesses that will be contributed to PT Portugal and, following our acquisition of PT Portugal may discover undisclosed liabilities or operational issues which couldwould have a material adverse effect on our business, resultUnitel’s financial position and results of operations or financial condition.and the value of our investment in Unitel.

FollowingAdverse political, economic and legal conditions in the completion of the Oi capital increase, we will face risks relating to the operations that we acquire in Portugal, AfricaAfrican and Asia, many of which are similar to the risks that we currently face in our Brazilian operations. However, as a result of the exposure of PT Portugal to the regulatory regimes of theAsian countries in which it operates, the competitive dynamics in the markets in which it provides services and the agreements that it has entered into with respect to its joint ventures to serve some of these markets, we will face additional risks that are generally described in publicly available information regarding Portugal Telecom and its operations. We cannot assure you that all of the risks relating to these regulatory regimes, markets or joint ventures have been disclosed by Portugal Telecom, that our management of these risks will be successful, or that unanticipated events will not have a material adverse effect on our business, result of operations or financial condition.

We and Portugal Telecom will be subject to business uncertainties and contractual restrictions while the business combination is pending.

Uncertainty about the effect of the business combination on employees, suppliers, partners, regulators and customersacquired investments may have an adverse effect on Oi, Portugal Telecom and TmarPart. These uncertainties could cause suppliers, customers, business partners and others that deal with Oi or Portugal Telecom to defer purchases, the consummation of other transactions or other decisions concerning their respective businesses, or to seek to change existing business relationships with them. In addition, employee retention may be particularly challenging until the business combination is consummated, as employees may experience uncertainty about their future roles in TmarPart and its consolidated subsidiaries. If key employees depart because of issues relating to the uncertainty and difficulty of integration, our business could be harmed. In addition, the merger plan restricts Oi and Portugal Telecom from undertaking major investments and taking other specified actions until the business combination occurs unless otherwise agreed. These restrictions may prevent Oi and Portugal Telecom from pursuing attractive business opportunities that may arise prior to the completion of the business combination.

The Memorandum of Understanding with respect to the business combination contains exclusivity provisions which prohibit us, Portugal Telecom and certain of our affiliates from soliciting or considering alternative proposals from any third party.

The Memorandum of Understanding with respect to the business combination contains exclusivity provisions which prohibit us, Portugal Telecom and certain of our affiliates from soliciting or considering alternative proposals from any third party. As a result, these provisions may prevent our company or Portugal Telecom from receiving or accepting an alternative proposal that could result in greater value to the shareholders of such entity.

Holders of Oi common shares, preferred shares and ADSs and Portugal Telecom ordinary shares and ADSs will be offered fixed numbers of TmarPart common shares and ADSs, which involves the risk of market fluctuations.

The parties to the merger have advised us that the exchange ratio in the merger will be determined in a manner such that the number of TmarPart common shares received by holders of Portugal Telecom ordinary share is equal to that holder’s pro rata portion of the TmarPart shares owned by Portugal Telecom following the completion of the merger of shares. Because the number of TmarPart shares owned by Portugal Telecom following the completion of the merger of shares will depend on the number TmarPart shares acquired by Portugal Telecom in exchange for the shares of PT Portugal in the global offering, the exchange ratio for the merger will not be determinable until the global offering has closed.

Holders of Oi common shares, preferred shares and ADSs, collectively referred to as Oi securities, will receive a fixed number of TmarPart common shares and ADSs, collectively referred to as TmarPart securities, in the merger of shares, rather than a number of TmarPart securities with a fixed market value. Holders of Portugal Telecom ordinary shares and ADSs, collectively referred to as Portugal Telecom securities, will also receive a fixed number of TmarPart common shares and ADSs, collectively referred to as TmarPart securities, in the merger rather than a number of TmarPart securities with a fixed market value.

There is no mechanism to adjust the exchange ratios for the merger of shares or the merger in the event that the market price of either the Portugal Telecom securities or the Oi securities increase or decrease significantly relative to the other. Consequently, (1) the market value of the TmarPart securities implied by the market values of the Oi securities and the exchange ratios in the merger of shares, and (2) the market value of the TmarPart securities implied by the market values of the Portugal Telecom securities and the exchange ratio in the merger, may fluctuate significantly from the date of this prospectus supplement, and the exchange ratios for the merger of shares and the merger might not be reflective of market price ratios of Oi securities relative to Portugal Telecom securities at the time of the completion of the merger of shares and the merger.

The market price of our securities may be adversely affected by arbitrage activities occurring prior to the completion of the merger of shares and the merger.

The market price of our securities may be adversely affected by arbitrage activities occurring prior to the completion of the merger of shares and the merger. These sales, or the prospects of such sales in the future, could adversely affect the market price for, and the ability to sell in the market, our securities before the merger of shares and the merger are completed and TmarPart securities after the merger of shares and the merger are completed.

TmarPart may have actual or potential conflicts of interest relating to the merger of shares, and TmarPart’s significant shareholders who negotiated the terms of the business combination may have different interests from your interests as a holder of securities of Oi.

TmarPart may have actual or potential conflicts of interest with our shareholders because Portugal Telecom, AGSA and Jereissati Telecom, the controlling shareholders of TmarPart and thus of Oi, exercise voting control over the boards of directors of TmarPart and Oi. While the exchange ratios for the merger of shares were determined in accordance with all applicable laws and regulations in Brazil and the exchange ratio for the merger will be determined in accordance with all applicable laws and regulations in Brazil and Portugal, these ratios may be higher or lower than, from the perspective of value to unaffiliated shareholders, those that could be achieved through negotiations between parties without cross-shareholding relationships. Other terms and conditions of the business combination may also differ from those that could have been achieved through negotiations between parties without cross-shareholder relationships, and our shareholders might have preferred such other terms, including any terms that might have enhanced the financial condition, liquidity or results of operations of Oi or PT Portugal.

In addition, the terms of the business combination include the use of funds of Portugal Telecom to subscribe for convertible debentures, the proceeds of which will ultimately be used to repay substantially all of the indebtedness of AG Telecom, LF Tel and TmarPart. This use of funds to subscribe for convertible debentures and to repay substantially all of the indebtedness of these shareholders of Oi might be different than the terms of a transaction that could have been achieved in negotiations between parties without cross-shareholding relationships. As a holder of our securities, you might have preferred different terms or a different use for Portugal Telecom’s funds.

Brazilian law does not (1) establish any specific, minimum or maximum exchange ratio, (2) require that the board of directors of TmarPart or Oi formally determine that the terms of the merger of shares or the merger as a whole are “fair,” either procedurally or financially, to its non-controlling shareholders, (3) establish any special committee or otherwise alter its corporate governance rules in connection with the merger of shares or the merger, or (4) impose any prohibition or limitation on the voting rights of the controlling shareholder.

Under the Brazilian Corporation Law, because the merger of shares involves a controlling and controlled company, we and TmarPart are required to disclose the ratio of the value of Oi shares and TmarPart shares calculated based on the net worth calculated at market prices (as if the assets of TmarPart and Oi had been sold), based on valuation reports prepared by an independent financial advisor. This exchange ratio is required to be

disclosed in order to provide the non-controlling shareholders with a parameter against which to evaluate the proposed merger of shares. The applicable exchange ratio calculated based on the criteria of net worth calculated at market prices will be determined following the completion of the global offering. Although this ratio is required under Brazilian law to be determined with respect to both the common and Oi preferred shares, holders of Oi preferred shares are not entitled to vote with respect to the merger of shares and will not have withdrawal rights if the merger of shares is approved. Although holders of Oi common shares are entitled to vote with respect to the merger of shares, the holders of these shares will not have withdrawal rights if the merger of shares is approved.

If the merger of shares is approved, holders of our preferred shares (including in the form of ADSs) will have to give up these securities, which provide certain rights that are not conferred by the TmarPart common shares that they will receive in return.

To compensate for not providing certain rights inherent to common shares, such as full voting rights, our preferred shares provide their holders with certain other rights mandated by the Brazilian Corporation Law for this share class that are not conferred by common shares. In the case of our preferred shares, these special preferred shareholder rights include a priority in the payment of a minimum non-cumulative dividend before dividends may be paid on our common shares, equal to the greater of 6.0% per year of theirpro ratashare of our capital or 3.0% per year of theirpro rata share of the book value of our shareholders’ equity. Although the merger of shares, if approved, will allow our preferred shareholders to acquire rights under the Brazilian Corporation Law inherent to common shares as a result of their receipt of TmarPart common shares bearing those rights, they will lose the special rights conferred to them by our preferred shares as a result of their surrender of those shares pursuant to the terms of the transaction.

Upon the completion of the merger of shares and the merger, TmarPart will have a substantial amount of existing debt, which could restrict its financing and operating flexibility and have other adverse consequences.

As of December 31, 2013, (1) we had R$35,854 million aggregate principal of outstanding debt, (2) Portugal Telecom had €7,371.1 million (R$24,012.2 million) aggregate principal of outstanding debt, and (3) TmarPart had R$3,259.1 million aggregate principal of outstanding debt, excluding the consolidated indebtedness of our company. Although we expect that all of TmarPart’s outstanding debt (other than the consolidated indebtedness of our company) will be repaid prior to the completion of the merger of shares and the merger, we and Portugal Telecom will remain subject to certain financial covenants that will limithinder our ability to incur additional debt. receive dividends from our African and Asian subsidiaries and investments.

The levelgovernments of TmarPart’s consolidated indebtedness after the completionmany of the merger of sharesAfrican and the mergerAsian countries in which we have investments have historically exercised, and the requirementscontinue to exercise, significant influence over their respective economies and limitations imposed by these debt instruments could adversely affect TmarPart’s financial conditionlegal systems. Countries in which we have investments may enact legal or results of operations. In particular, the terms of some of these debt instruments willregulatory measures that restrict the ability of TmarPart’sour subsidiaries to:

incur additional debt;

grant liens;

pledge assets;

selland investees to make dividend payments to us. Similarly, adverse political or dispose of assets;economic conditions in these countries may hinder our ability to receive dividends from our subsidiaries and

make certain acquisitions, mergers investees. Historically, Pharol has received dividends from the African and consolidations.

Furthermore, some of these debt instruments include financial covenantsAsian subsidiaries and investees that will require Oiwe have acquired, however, a limitation on our ability to maintain certain specified financial ratios. Additionally, the instruments governingreceive a substantialmaterial portion of those dividends could adversely affect our cash flows and liquidity.

In addition, our investments in these debt instruments contain cross-default or cross-acceleration clausesregions 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 occurrenceevolution of an eventregulated 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 default under onenew competitors and the rapid development of new technologies.

The development of partnerships in these instruments could trigger an event of default under other indebtedness or enablemarkets raises risks related to the creditors under other indebtedness to accelerate that indebtedness.

If TmarPart or its subsidiaries are unable to incur additional debt after the completionability of the merger of shares andpartners to jointly operate the merger, TmarPart may be unable to invest in its businesses and make necessary or advisable capital

expenditures, which could reduce future net operating revenue and adversely affect its profitability. In addition, the use of cash to service the indebtedness of TmarPart after the completion of the merger of shares and the merger will reduce the amount available to it to make capital expenditures.

If the growth in net operating revenue of the constituent companies in the merger of shares and the merger slows or declines in a significant manner, for any reason, TmarPart may not be able to continue servicing its debt. If TmarPart is unable to meet these debt service obligations or comply with these debt covenants, TmarPart could be forced to renegotiate or refinance this indebtedness, seek additional equity capital or sell assets. In this circumstance, TmarPart may be unable to obtain financing or sell assets on satisfactory terms, or at all. For more information regarding the debt instrumentsAny inability of our company and our subsidiaries,partners to operate these assets may have a negative impact on our strategy and our indebtedness as of December 31, 2013, see “Item 5. Operating and Financial Review and Prospects—Indebtedness.”

The recapitalization of TmarPart will increase its net indebtedness after the completion of the merger of shares and the merger as compared to the sum of the net indebtedness of our company and Portugal Telecom.

As part of the business combination, Portugal Telecom will purchase convertible debentures of (1) PASA and Venus RJ Participações S.A., or Venus, both subsidiaries of Andrade Gutierrez S.A., or AGSA, or the AGSA Holding Companies, and (2) EDSP and Sayed RJ Participações S.A., or Sayed, both subsidiaries of Jereissati Telecom S.A., or Jereissati Telecom, or the Jereissati Telecom Holding Companies, for R$4,788 million, the proceeds of which will ultimately be used to repay substantially all of the indebtedness of AG Telecom, LF Tel and TmarPart (excluding the consolidated indebtedness of our company). As of December 31, 2013, AG Telecom had R$650 million aggregate principal of outstanding debt, LF Tel had R$662 million aggregate principal of outstanding debt, and TmarPart had R$3,259 million aggregate principal of outstanding debt (excluding the consolidated indebtedness of our company).

As of December 31, 2013, Oi had R$35,854 million aggregate principal of outstanding debt and R$3,016 million of cash and cash equivalents, and Portugal Telecom had €7,371.1 million (R$24,012.2 million) aggregate principal of outstanding debt and €2,573.1 million (R$8,388.3 million) of cash and cash equivalents. As of December 31, 2013, Oi’s net debt (which we define as total indebtednessless cash and cash equivalents) was R$32,838 million and Portugal Telecom’s net debt was R$15,642 million. The use of the proceeds of the Venus and Sayed debentures to repay the indebtedness of AG Telecom, LF Tel and TmarPart will increase TmarPart’s net debt following the completion of the merger of shares and the merger as compared to the sum of the net debt of Portugal Telecom and Oi if Portugal Telecom were not to invest in the Venus and Sayed debentures.

As a result of these factors, the risks normally associated with significant amounts of debt, which could have important consequences to you, will be increased. TmarPart’s indebtedness could, among other things:

require TmarPart to use a substantial portion of its cash flow from operations to pay its obligations, thereby reducing the availability of its cash flow to fund working capital, operations, capital expenditures, dividend payments, strategic acquisitions, expansion of its operations and other business activities;

increase TmarPart’s vulnerability to general adverse economic and industry conditions;

limit, along with financial and other restrictive covenants in TmarPart’s debt instruments, its ability to borrow additional funds or dispose of assets; and

place TmarPart at a competitive disadvantage compared to its competitors that have less debt.

TmarPart may also need to refinance all or a portion of this debt on or before maturity, and it may not be able to do this on commercially reasonable terms or at all.

Oi’s ordinary shareholders may have withdrawal rights in connection with the business combination.

Brazilian legislation grants the right to withdraw from a company (against reimbursement of shares held) to dissenting shareholders, i.e., shareholders who do not agree with a general shareholders’ meeting resolution that

approves the merger of a company’s shares into another company. For this purpose, dissenting shareholders include those that have voted against the resolution, shareholders that did not vote and those who were not present at the relevant meeting. In the case of our shares, whenever withdrawal rights are granted, the reimbursement price is basedmaterial effects on our net asset value per share.results of operations.

The Brazilian legislation also sets forth that the right to withdraw does not apply to holder of a class or type of shares that has market liquidity and dispersion. Liquidity is evidenced when the type or class of share, or the certificate that represents it, is part of a general index representing a portfolio of securities in Brazil or abroad, as defined by the CVM. Dispersion is evidenced when the majority shareholder, the controlling corporation or other corporations under their control hold less than half of the issued shares of the applicable type or class.

We understand that holders of our common shares do not have withdrawal rights in case of approval of the merger of shares. However, the technical body of the CVM issued an official opinion on the matter stating that it understands that our common shares do have withdrawal rights in this case. We have filed a challenge to this opinion with the CVM, but no final decision has been rendered by the CVM. In addition, any decision by the CVM may be challenged by our company or our minority shareholders in Brazilian courts.

In the event we ultimately grant withdrawal rights to holders of our common shares, we may be required to make large cash payments in connection with the merger of shares, and such payments could decrease the cash balances available to TmarPart after the merger of shares and limit its ability to borrow funds or fund capital expenditures, which may adversely affect TmarPart and our shareholders following the merger of shares.

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.

AllWe are a Brazilian corporation and a majority of our operations and customers are located in Brazil, except for minor operations and the customers of these operations outside of 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;

other political, diplomatic, social and economic developments in or affecting Brazil.

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. Although we do not believe that Ms. Rousseff will significantly alter current governmental policies, weWe 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.

InstabilityIn 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 international financial system may adversely affect economic growthuncertainties 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 limit our accessnot publicly disclosed, as well as served to personally enrich the financial markets and, therefore, negatively impact our business and financial condition.

Global economic instability and related instability in the international financial system have had, and may continue to have, a negative effect on economic growth in Brazil. Although the United States, Europe and China have shown recent signs of recovery, the recoveryrecipients of the global economy, which depends onbribery scheme. As a result of the ongoing “Lava Jato” investigation, a number of factors,senior politicians, including a returncongressman and officers of job growththe 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 investmentstrading 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 private sectorfuture.

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 Congress voted to suspend President Rousseff from office for a period of up to 180 days during which time the Brazilian Senate will conduct an impeachment trial. Vice-President Michel Temer will serve as well asacting President of Brazil during this period. We cannot predict the timingoutcome of President Rousseff’s impeachment trial or its effect on the Brazilian economy. Moreover, there is strong popular pressure and several legal and administrative proceedings for the revocation of the exit from government credit easing policiesmandate or resignation of the Head of the Brazilian House of Representatives, which have led to further uncertainties. The political crisis prompted by central banks globally, is not certain. Continued or worsening volatility inthese investigations and proceedings could worsen the global financial markets could reduce the availability of liquidity and credit to fund the continuation and expansion of industrial business operations worldwide. A prolonged slowdown in economic activityconditions in Brazil could reduce demand for some of our services, which wouldand adversely affect our results of operations.operations and financial condition.

As a result of instability in the international financial system, our ability to access the capital markets or the commercial bank lending markets may be severely restricted at a time when we would like, or need, to access such markets, which could have an impact on our flexibility to react to changing economic and business conditions. The instability in the international financial system or a prolonged slowdown in economic activity in Brazil could have an impact on the lenders under our existing credit facilities, on our customers or on the ability of our suppliers to meet scheduled deliveries, causing them to fail to meet their obligations to us. If the instability in the international financial system continues, it could have an adverse effect on the demand for our services and our ability to fund our planned growth.

Depreciation of thereal 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 thereal and the U.S. dollar has varied significantly in recent years. For example, thereal/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. In 2008, primarily as a result of the international financial crisis, thereal depreciated by 31.9% against the U.S. dollar and prompted foreign investors to remove billions ofreais from the Brazilian Securities, Commodities and Futures Exchange (BM&FBOVESPA S.A. - Bolsa de Valores Mercadorias e Futuros), which we refer to as the BM&FBOVESPA. Therealappreciated against the U.S. dollar by 25.5% during 2009 and by 4.3% during 2010. Since that period, thereal2010, and has depreciated by 12.6%8.9% against the U.S. dollar during 2011, by 8.9% during 2012, and by 14.6% during 2013.2013, by 13.4% during 2014 and by 47.1% during 2015. In

addition, therealappreciated against the Euro by 10.4% during 2010, and has depreciated by 10.7% against the Euro during 2012, by 19.7% during 2013, was substantially unchanged during 2014 and depreciated by 31.7% in 2015.

A significant amount of our financial liabilities are denominated in or indexed to foreign currencies, primarily U.S. dollars and Euros. As of December 31, 2013,2015, R$14,94847,372 million of our consolidated financial indebtedness was denominated in a foreign currency.currencies other than thereal. When thereal 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 intoreais. If significant depreciation of thereal 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 thereal 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. Additionally,Historically, we currently have maintained currency swaps and non-deliverable forwards in place forto manage our exposure to most of our foreign currency debt. If the costDuring 2016, in connection with our consideration of potential plans to restructure our indebtedness, we have not rolled over our non-deliverable forwards and have selectively settled several of our long-term currency swap instruments increases substantially, we may be unableswaps. As a result, our exposure to maintain our hedge positions, resulting in an increased foreign currency fluctuations has increased substantially. If we are able to restructure our indebtedness in a manner satisfactory to our company, we expect 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 in turn lead to substantial foreign exchange losses.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.dollar and the Euro. We generally do not hedge against risks related to movements of thereal against foreign currencies. To the extent that the value of thereal 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 thereal 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 thereal 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 thereal 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 9.1% in 2008, (1.4)% in 2009, 11.3% in 2010, 5.0% in 2011, 8.1% in 2012, 5.5% in 2013, 3.8% in 2014 and 4.8%10.7% in 2013.2015. 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 4.3% in 2009, 5.9% in 2010, 6.5% in 2011, 5.8% in 2012, and 5.9% in 2013.2013, 6.4% in 2014 and 10.7% in 2015.

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 December 31, 2013,2015, we had, among other consolidated debt obligations, R$10,2958,950 million of loans and financings that were subject to the London Interbank Offered Rate, or LIBOR, R$6,361 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, R$5,1443,151 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 R$3,8431,515 million of loans and financings that were subject to the London Interbank Offered Rate, or LIBOR, and R$3,728 million of loans and financings that were subject to the IPCA.

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 10.64% per annum as of December 31, 2010 to 10.87% per annum as of December 31, 2011, decreased to 6.90% per annum as of December 31, 2012 and increased to 9.77% per annum as of December 31, 2013.2013, increased to 11.57% per annum as of December 31, 2014 and increased to 14.13% per annum as of December 31, 2015. A significant increase in any of these interest rates, particularly the CDI rate, 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 our 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 therealinto 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 inreais. 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, 2013,2015, our foreign-currency denominated debt was R$14,94847,372 million and represented 41.1%78.4% of our consolidated indebtedness. If we fail to make payments under any of these obligations, we will be in default under those obligations, which could reduce our liquidity as well as the market price of our 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 our ADSs or holders who have exchanged our 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 our common shares and preferred shares will hold thereais that it cannot convert for the account of holders of our ADSs who have not been paid. Neither the custodian nor The Bank of New York Mellon, as depositary of our ADS programs, orwhich we refer to as the depositary, will be required to invest thereais or be liable for any interest.

Risks Relating to Our Common Shares, Preferred Shares and ADSs

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

According to our by-laws and the Brazilian Corporation Law, we must generally pay our shareholders at least 25% of our 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 our 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 our preferred shares. Additionally, the Brazilian Corporation Law allows a publicly traded company like ours to suspend the mandatory distribution of dividends in any particular year if our board of directors informs our shareholders that such distributions would be inadvisable in view of our financial condition or cash availability. Holders of our preferred shares or Preferred ADSs may not receive any dividends or interest on shareholders’ equity in any given year if our board of directors makes such a determination or if our operations fail to generate net income.

Our preferred shares and Preferred ADSs have limited voting rights and are not entitled to vote to approve corporate transactions, including mergers or consolidations of our company with other companies, or the declaration of dividends.

Under the Brazilian Corporation Law and our by-laws, holders of our preferred shares and, consequently, our Preferred ADSs, are not entitled to vote at meetings of our shareholders, except in very limited circumstances. These limited circumstances directly relate to key rights of the holders of preferred shares, such as modifying basic terms of our preferred shares or creating a new class of preferred shares with superior rights. Holders of preferred shares without voting rights are entitled to elect one member and his or her respective alternate to our board of directors and our fiscal council. Holders of our preferred shares and Preferred ADSs are not entitled to vote to approve corporate transactions, including mergers or consolidations of our company with other companies, or the declaration of dividends. See “Item 10. Additional Information—Description of Our Company’s By-laws—Voting Rights.”

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

Under Brazilian law, only shareholders registered as such in our corporate books may attend our shareholders’ meetings. All common shares and preferred shares underlying our ADSs are registered in the name of the depositary. ADS holders may exercise the voting rights with respect to our common shares and the limited voting rights with respect to our preferred shares represented by our ADSs only in accordance with the deposit agreements relating to our 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, we are required to publish a notice of our shareholders’ meetings in certain newspapers in Brazil. To the extent that holders of our 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 we notify 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 our common shares or preferred shares. If the depositary fails to receive timely voting instructions for all or part of our 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 our ADSs have voting rights, they may not receive the voting materials in time to instruct the depositary to vote our 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 our ADSs or for the manner of carrying out those voting instructions. Accordingly, holders of our 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 our 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 we issue new shares in exchange for cash or assets as part of a capital increase, subject to certain exceptions, we must grant our shareholders preemptive rights at the time of the subscription of shares, corresponding to their respective interest in our share capital, allowing them to maintain their existing shareholding percentage. We may not legally be permitted to allow holders of our common shares, preferred shares or ADSs in the United States to exercise any preemptive rights in any future capital increase unless (1) we file 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, we 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 we consider important in determining whether to file such a registration statement. We cannot assure the holders of our common shares, preferred shares or ADSs in the United States that we will file a registration statement with the SEC to allow them to participate in any of our capital increases. As a result, the equity interest of such holders in our company may be diluted.

If holders of our 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 our 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 our 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 our ADSs that exchange our ADSs for our 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, our common shares or preferred shares. See “Item 10. Additional information—Exchange Controls” and “Item 10. Additional Information—Taxation—Brazilian Tax Considerations.”

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

Holders of our ADSs are not direct shareholders of our company and are unable to enforce the rights of shareholders under our by-laws and the Brazilian Corporation Law.

Our corporate affairs are governed by our by-laws and the Brazilian Corporation Law, which differ from the legal principles that would apply if we 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 our ADSs surrenders its ADSs and becomes a direct shareholder, its rights as a holder of our common shares or preferred shares under the Brazilian Corporation Law to protect its interests relative to actions by our 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 our 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.

Brazilian bankruptcy laws may be less favorable to you than bankruptcy and insolvency laws in other jurisdictions.

If we are unable to pay our indebtedness, then we may become subject to bankruptcy proceedings in Brazil. The bankruptcy laws of Brazil currently in effect are significantly different from, and may be less favorable to creditors than, those of certain other jurisdictions. Any judgment obtained against us in Brazilian courts in respect of any payment obligations under our debt instruments normally would be expressed in thereal equivalent of the U.S. dollar amount of such sum at the exchange rate in effect (1) on the date of actual payment, (2) on the date on which such judgment is rendered, or (3) on the date on which collection or enforcement proceedings are started against us. Consequently, in the event of our bankruptcy, all of our debt obligations that are denominated in foreign currency, will be converted intoreais at the prevailing exchange rate on the date of declaration of our bankruptcy by the court.

We are exempt from some of the corporate governance requirements of the New York Stock Exchange.

We are a foreign private issuer, as defined by the SEC for purposes of the Exchange Act. As a result, for so long as we remain a foreign private issuer, we 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. We are permitted to follow practice in Brazil in lieu of the provisions of the NYSE’s corporate governance rules, except that:

 

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

 

we are required to disclose any significant ways in which our corporate governance practices differ from those followed by domestic companies under NYSE listing standards;

 

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

 

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

The standards applicable to us are considerably different than the standards applied to U.S. domestic issuers. AlthoughRule 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, we are relying on a general exemption from this requirement that is available to us as a result of the features of Brazilian law applicable to our fiscal council. In addition, we are not required to, among other things:

 

have a majority of independent members of our board of directors;

 

have a compensation committee or a nominating or corporate governance committee of our 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.

We intend 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 the U.S. Foreign Corrupt Practices Act and similar antibribery laws outside of the United States.

The U.S. Foreign Corrupt Practices Act, or the FCPA, and similar anti-bribery 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-bribery 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-bribery 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 our ADSs may face difficulties in serving process on or enforcing judgments against us and other persons.

We are organized under the laws of Brazil, and all of the members of our board of directors, our executive officers and our independent registered public accountants reside or are based in Brazil. The vast majority of our assets and those of these other persons are located in Brazil. As a result, it may not be possible for holders of our ADSs to effect service of process upon us or these other persons within the United States or other jurisdictions outside Brazil or to enforce against us or these other persons judgments obtained in the United States or other jurisdictions outside Brazil. In addition, because substantially all of our assets and all of our directors and officers reside outside the United States, any judgment obtained in the United States against us 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 our 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 our 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 our 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 our ADSs made betweenby 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, we are unable to predict whether an interpretation applying such tax laws to dispositions of our ADSs between nonresidents could ultimately prevail in Brazilian courts. See “Item 10. Additional Information—Taxation—Brazilian Tax Considerations.”

We believe we were a passive foreign investment company for our taxable year ended December 31, 2015, which could result in adverse U.S. federal income tax consequences to U.S. Holders of our American depository shares or ordinary shares.

We 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 we intend 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 our common shares and preferred shares and the composition of our assets, we believe we were a PFIC for U.S. federal income tax purposes for our taxable year ended December 31, 2015. Furthermore, unless the value of our common shares and preferred shares increases and/or we invest a substantial amount of our cash and other passive assets in assets that produce active income, there is a significant risk we will be a PFIC for our taxable year ending December 31, 2016. The application of the PFIC rules is subject to uncertainty in several respects, and we must make a separate determination after the close of each taxable year as to whether we were a PFIC for such year. Because we believe we were a PFIC for our taxable year ended December 31, 2015, certain adverse U.S. federal income tax consequences could apply to a U.S. investor who holds our common shares, preferred shares or ADSs with respect to any “excess distribution” received from us and any gain from a sale or other disposition of our common shares, preferred shares or ADSs, and U.S. investors also may be subject to additional reporting obligations with respect to our common shares, preferred shares or ADSs. We do not intend to provide the information necessary for the U.S. investor to make a qualified electing fund election with respect to our common shares, preferred shares or ADSs. See “Item 10. Additional Information—Taxation – U.S. Federal Income Tax Considerations – Passive Foreign Investment Company Rules.”

The relative volatility and illiquidity of the Brazilian securities markets may adversely affect holders of our common shares, preferred shares and ADSs.

The Brazilian securities markets are substantially smaller, less liquid and more volatile than major securities markets in the United States. The BM&FBOVESPA, which is the principal Brazilian stock exchange, had a market capitalization of R$2,414 billion1.9 trillion (US$1,031490 billion) as of December 31, 20132015 and an average daily trading volume of R$7.46.8 billion (US$3.52.1 billion) for 2013.2015. In comparison, aggregate market capitalization of the companies (including U.S. and non-U.S. companies) listed on the NYSE was US$20.017.8 trillion as of December 31, 20132015 and the NYSE recorded an average daily trading volume of US$54.764.0 billion for 2013.2015. There is also significantly greater concentration in the Brazilian securities markets. The ten largest companies in terms of market capitalization represented approximately 51% of the aggregate market capitalization of the BM&FBOVESPA as of December 31, 2013.2015. The ten most widely traded stocks in terms of trading volume accounted for approximately 41%44% of all shares traded on the BM&FBOVESPA in 2013.2015. These market characteristics may substantially limit the ability of holders of our ADSs to sell the preferred shares underlying our 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 our ADSs themselves.

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

Brazilian law imposes the Tax on Foreign Exchange Transactions, or the IOF/Exchange Tax, on the conversion ofreais into foreign currency and on the conversion of foreign currency intoreais. 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 thereal 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 prospectus,annual report, all investments in the Brazilian financial and capital markets are subject to the IOF/Exchange Tax atrate 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 our company, due to higher transaction costs, and may negatively impact the price and volatility of our ADSs and common shares on the NYSE and the BM&FBOVESPA.

Our Recent History and Development

Prior to the formation in 1972Adoption of Telebrás, the Brazilian state-owned telecommunications monopoly, there were more than 900 telecommunications companies operating throughout Brazil. Between 1972 and 1975, Telebrás and its operating subsidiaries acquired almost all of the other telecommunications companies in Brazil and thus achieved a monopoly in providing public telecommunications services in almost all areas of the country.

Beginning in 1995, the Brazilian government undertook a comprehensive reform of Brazil’s telecommunications regulations. In July 1997, Brazil’s Congress adopted the Brazilian General Telecommunications Law (Lei Geral das Telecomunicações), which, together with the regulations, decrees, orders and plans on telecommunications issued by Brazil’s executive branch, provided for the establishment of a comprehensive regulatory framework introducing competition into the Brazilian telecommunications industry and promoting the privatization of Telebrás and its subsidiaries.

Privatization of Telebrás

In January 1998, in preparation for its restructuring and privatization, Telebrás spun-off its previously integrated mobile telecommunications operations from its fixed-line operations into separate companies. In May 1998, Telebrás was restructured to form 12 new holding companies, or the New Holding Companies, by means of a procedure under the Brazilian Corporation Law calledcisão, or spin-off. Virtually all of the assets and liabilities of Telebrás were allocated to the New Holding Companies, including Telebrás’s interest in its operating subsidiaries. The New Holding Companies consisted of:

eight holding companies each of which controlled one or more mobile services providers, each operating in one of the ten service regions into which Brazil had been divided for mobile telecommunications services and using the frequency range called Band A (other than one mobile services provider that operated in two regions and one region in which the mobile services provider was not part of the Telebrás system);

three regional holding companies, including Brasil Telecom Participações S.A., or Brasil Telecom Holding, and TNL, each of which controlled the fixed-line service providers that provided local and intraregional

long-distance service in one of the three service regions into which Brazil has been divided for fixed-line telecommunications; and

a holding company, which controlled Embratel, a provider of domestic (including interstate and interregional) and international long-distance service throughout Brazil.

We are the successor to Brasil Telecom Holding and TNL, two of the New Holding Companies in the fixed-line telecommunications business. In the restructuring and privatization of Telebrás, Brasil Telecom Holding was allocated all of the share capital held by Telebrás in the operating subsidiaries that provided fixed-line telecommunications service in Region II, including our company, and TNL was allocated all of the share capital held by Telebrás in the operating subsidiaries that provided fixed-line telecommunications service in Region I, including Telemar.

In August 1998, the Brazilian government privatized Telebrás by selling all of the voting shares that it held in the New Holding Companies, including Brasil Telecom Holding and TNL, to private-sector buyers.

Expansion of Fixed-Line Network in Rio Grande do Sul

In July 2000, we acquired the control of Companhia Riograndense de Telecomunicações, or CRT. CRT was the leading fixed-line telecommunications service company in the State of Rio Grande do Sul. In December 2000, CRT was merged with and into us.

Corporate Reorganization of Brasil TelecomTransformation Plan

Following the formation of Brasil Telecom Holding, it provided fixed-line telecommunicationschange in our senior management in 2014, we developed a plan to pursue business growth through innovative solutions that focus on enhancing our customers’ experience rather than merely selling our services, through nine separate operating subsidiaries, including our company, each of which provided telecommunications services in one of the nine states of Region II or the Federal District of Brazil. In February 2000, Brasil Telecom Holding implemented a corporate reorganization, which resulted in each of its other fixed-line operating companies being merged into our company.

Corporate Reorganization of TNL

Following its formation, TNL provided fixed-line telecommunications services through 16 separate operating subsidiaries, each of which provided telecommunications services in one of the 16 states of Region I. In August 2001, TNL implemented a corporate reorganization, which resulted in all of the other fixed-line operating companies being merged into our subsidiary Telecomunicações do Rio de Janeiro S.A., or Telerj. In September 2001, Telerj changed its name to Telemar Norte Leste S.A.

Entry into the Internet Service Provider Business

In October 2001, we formed BrTI to provide broadband internet services.

Entry into the Personal Mobile Services Business

In December 2002, we established our wholly-owned subsidiary, Oi Móvel S.A. (formerly known as 14 Brasil Telecom Celular S.A.), which we refer to as Oi Mobile, to provide personal mobile services (Serviço Móvel Pessoal) in Region II. In December 2002, Oi Mobile was granted an authorization by ANATEL to provide personal mobile services in Region II following its successful bid in an auction held for the authorization and the related radio frequency license. Oi Mobile commenced operations in September 2004.

Expansion of Our Internet Service Provider Business

In June 2003, we acquired all of the share capital of iBest Holding Corporation that we did not own. Prior to this acquisition, we owned 12.8% of the share capital of iBest Holding Corporation. iBest Holding Corporation

Acquisition of Submarine Fiber-Optic Cable System

In June 2003, we acquired the submarine fiber-optic cable system of 360 Networks Americas do Brasil Ltda. We refer to this system as GlobeNet. GlobeNet consists of a fiber optic cable system that connects the United States, Bermuda, Brazil, Venezuela and Colombia.

Entry into the Internet Protocol Business

In May 2004, we acquired substantially all of the share capital of Vant Telecomunicações S.A., or Vant, that we did not own. Prior to this acquisition, we owned 19.9% of the share capital of Vant. Vant offered Internet Protocol, or IP, services as well as other services to the corporate market throughout Brazil.

In May 2004, we acquired substantially all of the share capital of MetroRED Telecomunicações Ltda., or MetroRED, that we did not own. Prior to this acquisition, we owned 19.9% of the share capital of MetroRED. We have changed the corporate name of MetroRED to Brasil Telecom Comunicação Multimídia Ltda., or Brasil Telecom Multimedia. Brasil Telecom Multimedia is a leading local fiber optic network provider and also has an internet solutions data center in São Paulo which provides internet support to our customers. In October 2012, Vant merged with and into Brasil Telecom Multimedia.

Acquisition of iG

In November 2004, we acquired 63.0% of the capital stock of Internet Group (Cayman) Ltd., the parent company of Internet Group do Brasil Ltda., or iG. Prior to this acquisition, Brasil Telecom Holding owned 10.0% of the capital stock of Internet Group (Cayman) Ltd. In July 2005, we acquired an additional 25.6% of the capital stock of Internet Group (Cayman) Ltd. iG is a free internet services provider. iG is the leading dial-up ISP in Brazil and operates in the dial-up and broadband access markets. In October 2012, we implemented a corporate reorganization, which resulted in BrTI holding 100% of the capital stock of iG. In August 2013, BrTI transferred one share of iG to Telemar.

Consolidation of Call Centers

In December 2007, our subsidiary Brasil Telecom Call Center S.A. commenced operations, rendering call center services to us and our subsidiaries that demand this type of service. We invested approximately R$50 million in infrastructure and customer service technologies to create call centers in Goiânia, Campo Grande, Florianópolis, Brasília and Curitiba to replace our 30 pre-existing sites.

Acquisition by Telemar

On January 8, 2009, Copart 1 Participações S.A., or Copart 1, a wholly-owned subsidiary of Coari, itself a wholly-owned subsidiary of Telemar, acquired indirectly all of the outstanding shares of Invitel S.A., or Invitel, and 12,185,836 common shares of Brasil Telecom Holding owned by the shareholders of Invitel. At that time, Invitel owned 100% of the outstanding shares of Solpart Participações S.A., or Solpart, which owned 52.0% of the outstanding voting share capital, representing 19.0% of the outstanding share capital, of Brasil Telecom Holding, which, in turn, owned 67.2% of the outstanding share capital, including 99.1% of the outstanding voting share capital, of our company.

During 2008, Copart 1 had acquired 76,645,842 preferred shares of Brasil Telecom Holding, representing 33.3% of the outstanding preferred shares of Brasil Telecom Holding, and Copart 2 Participações S.A., or Copart 2, a wholly-owned subsidiary of Coari, had acquired 58,956,565 preferred shares of our company, representing 18.9% of our outstanding preferred shares.

As a result of the acquisition of Invitel, Telemar acquired indirect control of Brasil Telecom Holding and Brasil Telecom.

In connection with the approval in October 2010 of Telemar’s acquisition of control of our company by the Administrative Council for Economic Defense(Conselho Administrativo de Defesa Econômica), or CADE, the Brazilian antitrust regulator, Telemar entered into a Performance Commitment Term (Termo de Compromisso de Desempenho) containing obligations related to the wholesale market, specifically with regard to the provision of interconnection and Industrial Exploitation of Dedicated Lines (Exploração Industrial de Linha Dedicada), or EILD. Under this agreement, we must, among other obligations:

adopt specific procedures and provide specified assistance for our interconnection services and EILD customers; and

submit reports to CADE periodically and upon CADE’s request regarding our activities in these markets.

In addition, in connection with the approval by ANATEL in December 2008 of Telemar’s acquisition of control of our company, ANATEL imposed a number of conditions contained in the order granting the approval, some of which have already been fulfilled. The most significant of the remaining conditions require us to:

extend fiber optic cables to the city of Macapá within six months after the implementation of certain infrastructure connecting the cities of Tucuruí and Macapá by the power companies in this region;

expand our fiber optic network to 40 new municipalities in Regions I and II in each of 2012 through 2015;

make annual investments in research and development in each of the next ten years in amounts equal to at least 50% of the amounts of Telemar’s contributions to the Telecommunications Technology Development Fund (Fundo para o Desenvolvimento Tecnológico das Telecomunicações), or the FUNTTEL, which may be increased to 100% at ANATEL’s discretion.

Mandatory Tender Offers by Copart 1 and Copart 2

As a result of the acquisition of control of Brasil Telecom and Brasil Telecom Holding by Telemar on January 8, 2009, under Article 254-A of the Brazilian Corporation Law and CVM Instruction No. 361, of March 5, 2002, as amended, Telemar was required to offer to purchase any and all common shares of Brasil Telecom Holding and Brasil Telecom held by public shareholders.

As a result of these auctions, in June 2009 (1) Copart 1 acquired 40,452,227 common shares of Brasil Telecom Holding, representing 30.5% of the outstanding common shares of Brasil Telecom Holding and 11.2% of the outstanding share capital of Brasil Telecom Holding, and (2) Copart 2 acquired 630,872 common shares of Brasil Telecom, representing 0.3% of the outstanding common shares of Brasil Telecom and 0.1% of the outstanding share capital of Brasil Telecom.

Cost Control refers to various measures we are undertaking to reduce our costs and expenses and maximize the efficiency and sustainability of our operations. The solutions we developed in connection with the Transformation Plan were based on a comprehensive study of our customers’ telecommunications needs, with a view to improve the way our customers communicate.

In December 2014, we created a department tasked with monitoring and supporting the execution of the Transformation Plan, which we refer to as the Transformation Project Department. The Transformation Project Department consists of a team of employees from various departments, was initially led by a chief transformation project officer, who oversaw the process and reported directly to our chief executive officer. During 2015, members of the Transformation Project Department team met with senior management on a weekly basis to discuss progress on the more than 300 initiatives developed pursuant to the shares of holders who exercised their withdrawal rightsTransformation Plan. In late 2015, we created a strategy and new business department, which we refer to as the Strategy and New Business Department, which supplemented the Transformation Project Department’s role with respect to such shares) in exchange forinitiatives related to new business, human resources, communications, marketing and digitalization. In February 2016, the Strategy and New Business Department took over the chief transformation project officer’s role of overseeing the Transformation Project Department.

The Transformation Plan was divided into two key phases, each of their commonwhich can be summarized by four key goals. The first phase focused on short-term solutions designed to enable our company to remain competitive in a challenging macroeconomic environment. The four key goals of the first phase of the Transformation Plan are: (1) cost savings, (2) working capital improvements, (3) customer profitability improvements, and preferred shares(4) optimization of Telemar, respectively;our organizational structure. First phase initiatives included reductions in operating expenses, optimization of capital expenditures, reductions in working capital costs, changes in marketing strategies and

Coari retained pricing models and reductions in head-count related costs, such as overtime pay and travel expenses. We implemented several first phase initiatives during the Telemar shares exchangedfirst quarter of 2015, including the renegotiation of 69% of the number of contracts slated for Coari sharesrenegotiation, the reduction of the number of vehicles in our fleet by 13% and the reduction of headcount-related expenses by 37%, as a result, Telemar became a wholly-owned subsidiary of Coari;

The second phase consists of end-to-end initiatives designed to integrate our departments and enable our company to provide integrated service to our customers. The four key goals of the second phase of the Transformation Plan are: (1) process and organizational efficiency, (2) commercial and operational productivity, (3) cross-departmental improvement and (4) enhanced customer experience. Second phase initiatives combine elements of each of the pillars of the Transformation Plan to seek to deliver integrated solutions to our customers. An example of a second phase initiative was cancelled,the transformation of our call center operations, which was accomplished by revising our customer complaint procedures and each issuedcreating a specialized team of specially trained call center professional to handle all downgrade requests. This initiative involved changes to and then outstanding sharecollaboration among multiple departments within our company. We began implementing second phase initiatives in the second quarter of Brasil Telecom held by TNL was cancelled, other than 24,647,867 common shares2015 and will continue to do so. As of Brasil Telecom, which were transferredDecember 31, 2015, approximately 87% of the initiatives we developed pursuant to the treasuryTransformation Plan had been implemented. The remaining initiatives, many of Brasil Telecom;which are more complex and require more time to become fully operational, are in the process of being implemented. We believe that the

Transformation Plan initiatives were the most significant factors that led to increases in our revenues per RGU in 2015, the decline in operating expenses per RGU and a 17% reduction in customer complaint calls in 2015, in each issuedcase as compared to 2014.

Divestment of Non-Strategic Assets

Beginning in 2012, we entered into various transactions to monetize non-essential assets and acquire the services related to these assets at more favorable financial terms, with an aim to reduce future capital expenditures and maintenance expenses.

Sale of Mobile Communications Towers

In December 2012, we sold Sumbe Participações S.A., or Sumbe, our wholly-owned subsidiary, to São Paulo SPE Locação de Torres Ltda. for R$516 million. Sumbe owned approximately 1,200 communications towers and rooftop antennae used in our mobile services business. Contemporaneously with the sale of these communications towers and rooftop antennae, we entered into an operating lease agreement with a term of 15 years with Sumbe permitting us and our subsidiaries to continue to use space on these communications towers and rooftop antennae for our mobile services business.

In December 2013, we entered into an agreement with SBA Torres Brasil, Ltda., under which we agreed to sell to SBA Torres Brasil, Ltda. all of our equity interests in a subsidiary that owns 2,007 mobile telecommunications towersPharol in exchange for R$1,525 million, subject to the completion of certain customary conditions precedent. The parties have also agreed that, upon the transfer of such equity interests, we shall enter into long-term lease agreements to permit us to continue to use space on these communications towers for our mobile services business. We expect to complete this transaction by the first quarter of 2014.

Assignment and Lease of Fixed-Line Communications Towers

In August 2013, we completed the assignment of the right to use 4,226 fixed-line communications towers that formed part of our infrastructure for commercial operations by companies whose core operations consist of providing transmission tower and radiofrequency management and maintenance services. Upon the completion of these assignments, we received proceeds of approximately R$1,087 million. We have entered into agreements to lease the communications towers from the assignees for 20-year terms (renewable for another 20 years), effective upon completion of the assignments.

In November 2013, we completed the assignment of the right to use 2,113 fixed-line communications towers that formed part of our infrastructure for commercial operations by companies whose core operations consist of providing transmission tower and radiofrequency management and maintenance services. Upon the completion of these assignments, we received proceeds of approximately R$687 million. We have entered into agreements to lease the communications towers from the assignees for 20-year terms (renewable for another 20 years), effective upon completion of the assignments.

Sale of GlobeNet

In December 2013, we and our subsidiary BrT Serviços de Internet S.A., or BrTI, sold all of our equity interests in Brasil Telecom Cabos Submarinos Ltda. and its subsidiaries (other than Brasil Telecom de Venezuela S.A.), collectively known as GlobeNet, to BTG Pactual YS Empreendimentos e Participações. On January 17, 2014, the sale was concluded for an aggregate amount of R$1,779 million (based on the U.S. dollar-real exchange rate on January 15, 2014), resulting in a gain of approximately R$1,497 million after deducting the book value of the assets and related costs. GlobeNet’s principal assets consist of 22,500 kilometers of fiber optic submarine cables, composed of two rings of protected submarine cables, linking connection points between the United States, Bermuda, Colombia and Brazil. As part of this transaction, GlobeNet will supply guaranteed submarine cable capacity to us and our subsidiaries at a fixed price for a term of 13 years.

Proposed Business Combination

On October 1, 2013, we entered into a memorandum of understanding, or the MOU, with Portugal Telecom, AG Telecom, LF Tel, PASA, EDSP, Bratel Brasil, BES and Ongoing, in which we and they agreed to the principles governing a series of transactions, including the business combination described below.

The business combination transaction involves three principal components:

a capital increase of our company in which we expect to issue common shares and preferred shares in an underwritten offering for an aggregate of at least R$7,000 million in cash, and common shares and preferred shares to Portugal Telecom in exchange for the contribution by Portugal Telecom to our company of all of the shares of its subsidiary PT Portugal, which will at that time owns (a) all of the operating assets of Portugal Telecom, except interests held directly or indirectly in Oi and Contax Holding, and (b) all of Portugal Telecom’s liabilities at the time of the contribution;

a merger of shares (incorporação de ações) under Brazilian law, a Brazilian transaction in which, subject to the approvals of the holders of voting shares of our company and TmarPart, all of the shares of our company not owned by TmarPart will be exchanged for TmarPart common shares and we will become a wholly-owned subsidiary of TmarPart; and

a merger (incorporação) under Portuguese and Brazilian law, of Portugal Telecom with and into TmarPart, with TmarPart as the surviving company in which the shareholders of Portugal Telecom will receive an aggregate number of TmarPart shares equal to the number of TmarPart shares held by Portugal Telecom immediately prior to the merger.

In connection with the business combination, we expect that:

TmarPart will enter into several additional transactions designed to recapitalize TmarPart so that at the time of the merger of shares, TmarPart will have no net debt;

TmarPart and our company will enter into merger transactions in order to simplify the ownership structure of TmarPart;

The shares of TmarPart will be listed on the Novo Mercado segment of the BM&FBOVESPA and on the NYSE Euronext Lisbon, and ADSs representing the shares of TmarPart will be listed on the NYSE; and

The shareholders agreements among the shareholders of TmarPart will be terminated.

We believe that the business combination will:

permit the formation of a single large multinational telecommunications company based in Brazil with more than 100 million customers in seven countries with a total population of approximately 260 million people;

maintain the continuity of operations under the trademarks of Oi and Portugal Telecom in their respective regions of operation, subject to unified control and management by TmarPart;

further consolidate the operations of our company and Portugal Telecom, with the goal of achieving significant economies of scale, maximizing operational synergies, reducing operational risks, optimizing efficient investments and adopting best operational practices;

strengthen the capital structure of TmarPart, facilitating its access to capital and financial resources;

consolidate the shareholder bases of our company, Portugal Telecom and TmarPart as holders of a single class of common shares or ADSs traded on the Novo Mercado segment of the BM&FBOVESPA, the NYSE and NYSE Euronext Lisbon;

diffuse TmarPart’s shareholder base, as a result of which no shareholder or group of shareholders will hold a majority interest in TmarPart’s capital;

result in the adoption by TmarPart of the corporate governance practices of the Novo Mercado segment of the BM&FBOVESPA; and

promote greater liquidity of the TmarPart common shares than currently is available to holders of our shares and Portugal Telecom’s shares.

Oi Capital Increase

As part of the Oi capital increase, Portugal Telecom is expected to subscribe for common shares and preferred shares of our company and settle this subscription through the contribution of all of the shares of PT Portugal as described below. In addition, we expect that Caravelas will subscribe for common shares and preferred shares in the cash portion of the Oi capital increase with a purchase price equivalent to the difference between R$2.0 billion and the amount of subscription orders placed in the offering by TmarPart’s shareholders, other than Bratel Brasil.

Overview of PT Portugal

In anticipation of the business combination, prior to the settlement of the Oi capital increase, Portugal Telecom will contribute all operating assets directly or indirectly owned by Portugal Telecom, except equity interests held directly or indirectly in our company, Contax Holding and Bratel B.V., to PT Portugal, and we expect that PT Portugal will assume all of Portugal Telecom’s liabilities. In addition to the interests held directly or indirectly in our company and Contax Holding, we understand that Portugal Telecom will retain R$4,788 million in cash and cash equivalents to be used to purchase convertible dentures of the AGSA Holding Companies and the Jereissati Telecom Holding Companies, and cash and cash equivalents equal to the amount of its remaining liabilities following the contribution of PT Portugal to our company. Prior to the consummation of the Oi capital increase, Portugal Telecom is expected to undertake a series of transactions with the purpose of disposing of its interests in CTX Participações S.A., a company controlled by AG Telecom, LF Tel and Portugal Telecom, or CTX, and Contax Participações S.A., a company controlled by CTX, or Contax Holdings.

Following the contribution of these assets to PT Portugal, PT Portugal will provide telecommunications services in Portugal and in certain countries in sub-Saharan Africa and Asia. In Portugal, PT Portugal will provide services in the following customer categories:

Residential services, which include integrated networks inside the customer’s home, enabling the simultaneous connection of multiple devices, including fixed line telephone, TV (including IP TV and DTH satellite pay-TV services), game consoles, PCs, laptops, tablets and smartphones. PT Portugal provides these services through its subsidiaries, in particular PT Comunicações S.A., or PT Comunicações.

Personal services, which are mobile telecommunications services, such as voice, data and Internet-related multimedia services provided to personal (i.e., individual) customers through PT Portugal’s subsidiary TMN—Telecomunicações Móveis Nacionais, S.A., or TMN.

Enterprise services, including Corporate and SME /SoHo services, which provide PT Portugal’s corporate and medium and small business customers with integrated data and business solutions, as well as Information Technology/Information Systems, or IT/IS, and business process outsourcing, or BPO, services.

Wholesale and other services, which primarily include wholesale telecommunications services, public pay telephones, the production and distribution of telephone directories and other services in Portugal.

In addition, PT Portugal will have significant interests in telecommunications companies in Angola, Cape Verde, Namibia and São Tomé and Principe in Africa and East Timor in Asia.

In connection with the business combination, on February 19, 2014, PTB2 S.A, or PTB2, and Bratel Brasil, both subsidiaries of Portugal Telecom, entered into subscription agreements to purchase convertible debentures to be issued by the AGSA Holding Companies and the Jereissati Telecom Holding Companies, for an aggregate of R$4,788 million. Each of the AGSA Holding Companies and Jereissati Telecom Holding Companies are expected to use the proceeds of these debentures to subscribe to convertible debentures of their subsidiaries, including AG Telecom and LF Tel, which will use the proceeds of their debentures to repay all of their outstanding indebtedness debt and subscribe to convertible debentures of TmarPart, which is expected to use the proceeds of its debentures to repay all of its outstanding indebtedness. Under the subscription agreements for these debentures, settlement of the issuance and sale of these debentures is expected to occur on the date of the settlement of the Oi capital increase.

Corporate Reorganization of TmarPart

the merger of AG Telecom with and into PASA, the merger of LF Tel with and into EDSP, and mergers of PASA and EDSP with and into Bratel Brasil;

the disproportionate partial split-off of TmarPart with the split-off shares, representing 99.9% of Bratel Brasil’s shares of TmarPart, merging into Bratel Brasil;

the mergers of Marnaz, Venus, Sayed and PTB2 with and into TmarPart.

As a result of the recapitalization of TmarPart, the conversion of the debentures described above and the TmarPart reorganization, we expect that TmarPart will own 126.6 million of our common shares and 96.2 million of our preferred shares and that the shareholding structure of TmarPart will be as set forth in the chart below.

LOGOLOGO

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 businessSME and corporate markets throughout Brazil.

Residential Services

Our primary services to the residential market are fixed-line voice, services, broadband services from fixed-line devices, subscription televisionand 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.

We identified cost savings and customer profitability initiatives as two of the pillars of the first phase of the Transformation Plan, which phase was largely implemented in 2015. As a result, we decreased our commercial efforts throughout the year in order to reduce sales expenses and capital expenditures. In late 2015, however,we increased commercial efforts by launching several plans aimed at reducing costs and offering more comprehensive services to our customers at higher prices. These higher-value offerings increased our ARPU in the residential services business even as our customer base decreased.

Also in 2015, our Residential Services business launched a series of initiatives aimed at increasing convergence among our product offerings, one of the key pillars of the Transformation Plan. As a result, offerings of our bundled services took on increasing importance, as they provide a better and more integrated experience for our customers while also increasing our ARPU.

Bundled Services

Our bundled services offerings adopted as part of the Transformation Plan have focused on increasing our profitability by providing a more comprehensive mix of higher-value services to our customers. In 2015, we focused 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 bundled services in the “Oi Total” and “Oi Conta Total” portfolios. We believe that these measures, together with oursimplified plan offeringsin the Residential Services business, resulted in an ARPU increase for each of our residential services (fixed-line voice, broadband and Pay-TV services) in 2015.

In addition, we believe bundled offerings build customer loyalty and serve to reduce churn rates as compared to standalone services. 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 for up to three months 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 Embratel and Telefônica Brasil offer broadband services at higher speeds than us. However, neither company has a quadruple-play bundle, such asOi Total Completo, that combines fixed-line voice, broadband, Pay-TV and mobile services. 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 launchedOi Total, a residential services bundle designed to increase our market penetration and profitability by attracting new customers and offering a higher number of servicers per user. EachOi Total plan includes fixed-line voice and broadband services with speeds of up to 35 Mbps through VDSL. CertainOi Totalplans also include Pay-TV and/or mobile services.Oi Total Completo, for example, is our quadruple-play package

that includes fixed-line voice, broadband, Pay-TV, as well as mobile services. The integrated processes (including single billing, joint installation and unified customer service) ofOi Total have also allowed us to generate greater operational efficiencies, thereby reducing our operating costs. By December 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. As of December 31, 2015, 75.6% of our fixed-line customers subscribed to one of the plans in ourOi Total portfolio. In March 2016, we launchedOi Total in the remaining Brazilian states where we offer fixed-line services.

Our Oi Totalportfolio reinforces our convergence strategy, which is one of the pillars of the Transformation Plan.Oi Total embodies the multi-product concept, 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 mobile voice services offered byOi Total include the all-net model for voice and robust data packages also offered byOi Livre andOi Mais, in addition to offering extensive movie, TV and internet content that is available for streaming anytime, anywhere throughOi Play, our content platform that is free of charge for all of our customers. Since its launch in September 2015,Oi Playhas shown potential for growth and future revenue generation.

Oi Conta Total

In addition to the launch ofOi Total, we continued to offer our legacyOi Conta Total portfolio in 2015.Oi Conta Total is a triple-play plan that provides fixed-line and mobile voice services, broadband services, mobile data and unlimited text messages to subscribers of any provider. In addition,Oi Conta Totalprovides unlimited long-distance calls to our fixed-line and mobile subscribers (except for the low-cost version of this plan,Conta Total Light). On December 31, 2015, 11% of our fixed-line customers subscribed to one of the plans in theOi Conta Total portfolio.

OurOi Conta Total plan permits subscribers to make unlimited local calls to any of our fixed-line or mobile customers and includes an allowance of minutes selected by the customer for use to make long-distance calls and local calls to customers of other service providers. Subscribers also elect the speed of their fixed-line broadband service, which is available under this plan at speeds ranging from 2 Mbps to 15 Mbps. Subscribers to this plan are entitled to access our Oi Wi-Fi hotspots, and subscribers who elect speeds of 5 Mbps or greater are provided with a complimentary wireless router. Subscribers can elect add-on features for this plan, including mobile data plans, unlimited text messages to subscribers of any provider and unlimited long-distance calls to our fixed line or mobile customers.

As part of our emphasis on offering bundled services that increase profitability and build customer loyalty, in 2015 we also offered ourOi Conta Total Smartphone plan, which has the same structure asOi Conta Totalbut included ourOi Smartphone data plan and unlimited text messages. Subscribers to this plan receive a smartphone, mini-modem or tablet at a subsidized price and are able to access our network of Oi Wi-Fi hotspots.

In March 2016, we discontinued offeringOi Conta Total as an independent portfolio and moved these offerings under the umbrella ofOi Totalunder the brand nameOi Total Conectado.

Pay-TV and Broadband Bundles

Subscribers to our internet protocal Pay-TV, IP TV, service may subscribe to ourOi TV Mais HD package, together with a broadband subscription at 100 Mbps, or ourOi 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, 2013,2015, we and had approximately 9.314.4 million local fixed-line customers in Region Iour fixed-line service areas (including customers of our SME and approximately 5.4 million local fixed-line customers in Region II.Corporate Services). 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.

We continually monitor market trends and the usage profile of our customer to assist us in designing new plans and promotions in order to retain our existing customers and attract new customers to our fixed-line voice services.

Broadband Services

We provide high-speed internet access services using ADSL technology, which we refer to as broadband services to residential customers in the primary cities in Region I and Region II under the brand name “Oi Velox.”our fixed-line service areas. As of December 31, 2013,2015, we offered broadband services in 2,8004,699 municipalities in Region I and 1,800 municipalities in Region II. As of December 31, 2013, we had 5.35.7 million residential ADSLbroadband customers in Regions Iour fixed-line service areas (including customers of our SME and II.

Corporate Services). 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 300 kbps2 Mbps to 1535 Mbps. To attract customers to this service, we offer new subscribers complementary anti-virus software and backup services. We offerservices, as well as a free wireless router with subscriptions at speeds of 5 Mbps or more.

We offer bundles of voice and broadband services to our fixed-line subscribers at rates that are lower than the combined rate for separate comparable voice and broadband subscriptions. We are engaged in capital expenditure programs to upgrade the broadband speeds that we are able to offer and 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.

We continue to strategically invest in areas where we see the greatest potential for sales and growth. Our two primary competitors in broadband services, Embratel and Telefônica Brasil, both offer broadband at higher speeds

than our offerings. As a result, in 2015 we devoted a substantial portion of our capital expenditures in investments to our network to increase the available broadband speeds 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 2015.

In September 2015, we launched high-speed VDSL broadband service with offers ranging from 15 to 35 Mbps. We expect to be able to offer even greater speeds as we continue to invest in our broadband network infrastructure.

This plan is available in most Brazilian states and, in addition to the features of theOi Fixo Ilimitado plan, permits a subscriber to make unlimited local calls to our fixed-line and mobile customers from a mobile device.

Personal Mobility Services

Our personal mobility services arePersonal 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, 2013,2015, we had an aggregate of approximately 50.245.9 million subscribers for our mobile services, including subscribers to our bundled plans. As of December 31, 2013, 83.3%2015, 85.2% of our mobilepersonal mobility voice customers subscribed to pre-paid plans and 16.7%14.8% subscribed to post-paid plans.

As part of our efforts under the Transformation Plan to increase profitability and enhance our customers’ experience, in 2015 we launched three new portfolios of mobile services plans:Oi Mais for the post-paid market,Oi Livre for the pre-paid market andOi Mais Controle as a hybrid solution. All of these plans provide simpler options, data allowances without usage restrictions, and (with the exceptionOi Mais Controle Básico, the basicOi Mais Controleplan) all-net minutes. The introduction of these new offerings is 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 Services

Post-Paid Voice Services

Post-paid customers pay a monthly subscription fee and are billed on a monthly basis for services provided during the previous month. Post-paid plans include voice mail, caller ID, conference calling, call forwarding, calls on hold and special services. We believe that our new offerings in the post-paid market enable us to improve revenues and market share by offering a mix of services to the post-paid market at more attractive prices.

Our “

In November 2015, we launched theOi Mais portfolio for the post-paid market.Oi Mais plans offer a substantial increase in the size of data packages with no usage restrictions, all-net minutes to call customers of any operator anywhere in Brazil and a reduced one-time tariff for calls made to customers of any operator in Brazil in excess of the monthly plan allowance. We believe the introduction of all-net plans will eliminate the community effect among voice customers using such plans. Moreover, we believe our new 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.

Oi Mais plans range from R$79.90 per month to R$149.90 per month. They provide between 250 minutes and 3,000 minutes of calls and offer between 3 GB and 10 GB of 4G data to be used freely (including on social networking sites). AllOi Mais plans offer access to Oi Wi-Fi and unlimited text messaging to customers of any operator.

We continue to offerOi Conta Conectado 50, our traditional portfolio of plans, permitwhich provides an unlimited on-net mobile plan for local and long distance voice services and an all-net plan for fixed-line services. TheOi Conta Conectado 50plan also provides a subscriber to make unlimited local calls to our fixed-line andlimited off-net voice package for mobile subscribers and includes an allowance of minutes selected by the customer for use to make calls to customers of other service providers.operators and 500 MB of data. In addition, customers can choose one among three add-ons: text messagesDecember 2015, we stopped offering new subscriptions to customers of other providers, long distance callsthe low-cost planOi Conta 100, which offered voice only (no data) to our fixed-line and mobile subscribers, and rollover minutes. Customers can share the plan with userscustomers. As of as many as five separate mobile devices by paying a monthly fee per line. Subscribers can buy unlimited add-on features for this plan, including mobile data plans, unlimited text messages to subscribers of any provider and unlimited long-distance calls to our fixed line or mobile customers.

We also offer our “December 31, 2015,Oi Smartphone” plan which (1) permits a subscriber to make unlimited local calls to our fixed-line and mobile subscribers and includes an allowance of minutes selected by the customer for use to make calls to customers of other service providers, and (2) permits unlimited access to our 3G network and our network of WiFi hotspots and unlimited text messaging. We offer smartphones at subsidized prices to new subscribers to ourOi SmartphoneConta Conectado plan. Our customers can also include as many as five separate mobile devices in the plan by paying a monthly fee per line. Subscribers can buy add-on features for this plan, including unlimited long-distance calls to our fixed line or mobile customers.

We also offer hybrid plans under the brand name “Oi Controle” for customers who wish to combine the cost savingsrepresented 84% of our total post-paid plans with the self-imposed limits of our pre-paid plans. “Oi Controle” subscribers are permitted to make unlimited local and long-distance calls to our mobile and fixed-line subscribers and purchase credits that can be used for text messaging, internet access and calls to customers of other providers. Credits can be bought through point of sale machines in retail stores, ATMs or mobile applications such as “Minha Oi” and “Recarga Oi.”base.

Pre-Paid Voice Services

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 asMinha Oi andRecarga 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 regularlyAfter conducting a comprehensive ten-month study of the telecommunications consumption habits in Brazil, in November 2015 we launched ourOi Livre portfolio for the pre-paid market, which includes significant increases in data allowances and a flat fee for all-net calls (with the exception ofOi Livre Por Dia, our per-day pre-paid mobile plan) to customers of any operator in Brazil. This initiative changes 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 variousofOi Livre was a strategic move given the recent 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 and promotions designedthat allow access to incentivize the purchase and usegreat variety of credits byapplications available for smartphones.

Oi Livre allows flexibility to our pre-paid customers. In September 2013, we launched the “Oi Galeraconsumers by offering monthly, weekly, daily and per-minute plans. Our monthly plan has a voice,300 minute allowance for calls to all Brazilian landlines and mobile subscribers, plus a 1GB data SMSpackage and 500 text

messaging, music messages for R$40 per month. Our weekly plan includes a 75 minute allowance for calls to all Brazilian landlines and WIFI internetmobile subscribers, plus a 400MB data package and 300 text messages for R$10 per week. We also offer a weekly plan aimed at young consumers whose values, perceptionsfor those who still value unlimited on-net calls, which includes a 250MB data package and consumption patterns are linked to online connectivity300 text messages for R$8 per week. Our daily plan has unbundled voice and data sharing. To promote the plan and attract new customers, we conducted several field campaigns where we distributed or sold SIM cards and encouraged customers who enrolled in the plan to use a Facebook application to invite their friends to join. The “Oi Galera” planpackages, each of which is being offered for R$0.99 per day of use. During the launch phase of this plan, “Oi Galera” SIM cards are not available for sale in stores.

In October 2013,less than R$1 per day. Finally, we launchedoffer a new pre-paid promotion called“Tudo Por Dia.”This promotion is part of our strategy of simplificationper minute plan with 60 MB daily for data usage and service convergence.“Tudo Por Dia” subscribers pay R$0,10 for the first call of the day and are allotted a certain number of minutes that vary according to region for local and long-distance calls to our mobile and fixed-line customers. This promotion also offers subscribers 530 text messages, and 5MBcalls to any landline or mobile subscriber in Brazil for R$0.30 per minute. Our monthly and weekly plans have a higher ARPU relative to our other plans, and they help us to achieve the objectives set forth in the Transformation Plan. Since its launch,Oi Livre has acquired 6.2 million customers and, as of data for R$0.50 per day for each service. A subscription to this promotion has minimum recharge requirements and a monthly promotion maintenance fee.December31, 2015,Oi Livre represented 15.9% of our total pre-paid base.

OurUnder our pre-paid voice plans, our customers may also exchange the credits that they purchase for additional services, such as:

  

Bônus Extra, which permits our customers to purchase additional minutes for use for local or long-distance calls to our fixed-line or mobile subscribers at discounted rates;

 

  

Pacote de Dados, which permits our customers to purchase a specified data allowance for use on their handsets; and

 

  

Pacote de SMS, which permits our customers to purchase the ability to send a specified number of text messages.

In keeping with the Transformation Plan’s focus on cost control and increasing profitability, throughout 2015 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 Services

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.

In November 2015, we launched theOi 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 theOi Mais customers, such as data packages with no usage restrictions, unlimited text messaging and (with the exception of theOi Mais Controle Básicoplan) all-net minutes to call customers of any operator anywhere in Brazil. We believe these new 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.

TheOi Mais Controle plans range from R$34.90 per month to R$54.90 per month. They offer between 1GB and 2GB of data to be used freely (including on social networking sites), between 250 and 500 all-net minutes (with the exception of theOi Mais Controle Básico plan), and unlimited text messaging to customers of any operator (with the exception of theOi Mais Controle Básico plan). If customers require additional credits under theOi Mais Controle plans, they can be purchased through point of sale machines in retail stores, ATMs or mobile applications such asMinha Oi andRecarga Oi.

TheOi Mais Controle Básico plan allows customers to make unlimited local and long-distance calls to our mobile and fixed-line subscribers (on-net calls) and offers 1GB of data. Customers can also purchase credits that can be used for calls to customers of other providers (off-net calls) and other add-on services.

Until November 2015, we offered hybrid plans under the brand nameOi Controle, which lack bad debt risk and have a favorable impact on working capital.Oi Controle allows customers to make unlimited local and long-distance calls to our mobile and fixed-line subscribers (on-net calls) and purchase credits that can be used for calls to customers of other providers (off-net calls) and other add-on services.Oi Controle is composed of five plans. One of the plans,Oi Controle Voz, offers a credit of R$10.90 for customer use on a pay-as-you go plan in addition to the above benefits. The other four plans include mobile data, unlimited text messages to our mobile customers, limited voice and text message plans to customers of other operators and access to our Wi-Fi hotspots. In keeping with the Transformation Plan’s focus on cost control and profitability of the customer base, in the second half of 2015 we disconnected all inactive users of our hybridOi Controleplan, which reduced certain unnecessary costs. As of December 31, 2015,Oi Controlerepresented 41% of our total post-paid base.

Mobile InternetData Only Services

We offer post-paid and pre-paid mobile data communicationcommunications services to customers thatwho 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. As with our post-paid voice plans, 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. We also offer internet access for a daily fee to customers who do not subscribe to a monthly plan. In December 2014, we began the practice of blocking access to data services for pre-paid customers who exceeded their data allowances. For post-paid data packages, we continue to throttle the speed of service for customers who exceed their data allowances.

Post-Paid Services

We offer a variety of post-paid mobile data communications plans that provide data allowances from 100300 MB to 510 GB for smartphones and from 300 MB to 10 GB for tablets and laptop computers and provide data transmission at speeds of 1 Mbps (3G network) or 5 Mbps (4G network).

Mobile Long-Distance

Each mobile subscriber in Brazil is registered in a geographic area (identified by the corresponding area codes, such as 11 (São Paulo) and 21 (Rio de Janeiro)), which we refer to as the subscriber’s home registration area. A call originated by a mobile subscriber registered in one home registration area to a mobile subscriber registered in another home registration area, is classified as a mobile long-distance call.

We provide mobile long-distance services originating from Region I and Region II through network facilities and through interconnection agreements with Telefônica Brasil in Region III and each of the other principal mobile services providers operating in Brazil that permit us to interconnect directly with their local fixed-line and mobile networks.

The implementation of the Transformation Plan throughout 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 with information technology services.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

In addition, in the second quarter of 2012, we launched our “

OurOi GestãoSmart Office service provides a system to control daily work and productivity of employees working remotely, including through whichthe use of biometrics. The platform offers a connection between the home environment and the corporate network, providing unified communication options including chat, voice, video, conferencing and document sharing along with corporate applications for cloud computing.

In response to the reduced demand for traditional telecommunications services due to the challenging macroeconomic environment in Brazil, we offerhave focused our new offerings in 2015 on information technology infrastructure services. As of December 31, 2015, approximately 15% of our corporate clients managed servicescustomers had contracted for their mobile devices. This service is focused on providing logistics and security solutions relatingat least one information technology service. In 2015, our revenues from information technology offerings increased as compared to mobile devices.2014.

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.

Services for Other Telecommunications Providers

We offer specialized 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, and traffic transportation through our physical infrastructure.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 local fixed-line, 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 local fixed-line, 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;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 Embratel 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 local fixed-line services, domestic long-distance services, mobile services, interconnection, EILD and SLD services are subject to regulation by ANATEL, subject to certain exceptions relating to the rates we charge under alternative fixed-line and mobile plans that we are authorized to offer to our customers. For information on ANATEL regulation of our rates, see “—Telecommunications Regulation—Regulation of the Brazilian Telecommunications Industry—Regulation of Fixed-Line Services—Rate Regulation,” “—Regulation of the Brazilian Telecommunications Industry—Regulation of Mobile Services—Personal Mobile Services Rate Regulation,” “—Regulation of the Brazilian Telecommunications Industry—Interconnection Regulations,” and “—Regulation of the Brazilian Telecommunications Industry—Regulation of Data Transmission and Internet Services.Industry.

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.

Local Fixed-Line Rates

Local Rates

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. As of December 31, 2013, 17.4% of our local fixed-line customers subscribed to the Basic Plan per Minute or the Mandatory Alternative Service Plan.

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. The monthly subscription fee forAs of December 31, 2015, 13.6% of our local fixed-line customers subscribed to the Basic Plan per Minute includes the use of 200 local minutes per month by residential customers and 150 local minutes per month by commercial customers and trunk line customers. The monthly subscription fee foror the Mandatory Alternative Service Plan includes the use of 400 local minutes per month by residential customers and 360 local minutes per month by commercial customers and trunk line customers. We deduct only two local minutes from a Basic Plan per Minute customer’s monthly allotment and four minutes from a Mandatory Alternative Service Plan customer’s monthly allotment for each local call made, regardless of the duration of the call, during off-peak hours. If the minute limits are exceeded, customers will incur additional metered-minute charges, the prices of which vary depending on whether the customer is a Basic Plan per Minute subscriber or a Mandatory Alternative Service Plan subscriber. If a customer does not use all of the minutes covered by the monthly subscription fee, the minutes cannot be carried over to the next month.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 the offering of those plans to our customers. In general, ANATEL does not raise objections to the terms of these plans. As of December 31, 2013, 82.6%2015, 86.4% of our local fixed-line customers subscribed to alternative plans.

Under our fixed-line rate plans, we charge for calls on a per-minute basis. There is a minimum charge period of 30 seconds for every call. However, calls of three seconds or less are not charged, except in certain specific instances as provided for in ANATEL regulations.

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 and Telemar may charge by an average of 0.66% as of October 23, 2010, 1.97% as of December 24, 2011 and 0.55% as of February 8, 2013.

2013, decreased the rates that we may charge by an average of 0.10% as of April 18, 2014, and increased the rates that we may charge by an average of 3.6% as of June 13, 2015. 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 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 VU-M 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-1 ratesVC Rates that we are permitted to charge. ANATEL authorized our company and Telemar to increase our VC-1 rates by an average 0.98% as of February 9, 2010. Discounts from the VC-1 rates approved by ANATEL may be granted to customers without ANATEL approval. In November 2011, ANATEL adopted new regulations under which ANATEL was authorized to reduce the then-current VC-1 rates by as much as 18% in 2011, 12% in 2012 and 10% in 2013, after giving effect to an inflation adjustment based on the IST measured from June 2009. In February 2012, ANATEL ordered us to reduce our VC-1 ratesVC Rates by approximately 10%, although we are appealing the timing of the application of this rate decrease to our company as our VC-1 rateVC Rates was increased in Region I by 1.54% in accordance with our application for this increase in February 2012. In March 2013,

ANATEL reducedhas changed our VC-1 rates as follows:

In February 2014, reduced by approximately 18% and 33.5% in RegionRegions I and Region II, respectively.

In August 2014, increased by approximately 18.6%1.5% and 8%,3.3% in Regions I and II, respectively.

In February 2015, reduced by approximately 21.8% and 21.3% in Regions I and II, respectively.

In August 2015, increased by approximately 5.5% in Regions I and II.

ANATEL has changed our VC-2 and VC-3 rates as follows:

Domestic Long-Distance

In February 2014, reduced our VC-2 rate by 12.1% and 27.5% in Regions I and II, respectively, and reduced our VC-3 rate by approximately 10.6% and 26.4% in Regions I and II, respectively.

In August 2014, increased both our VC-2 and VC-3 rates by approximately 1.5% and 3.1% in Regions I and II, respectively.

In February 2015, reduced our VC-2 rate by 13.6% and 12.4% in Regions I and II, respectively, and reduced our VC-3 rate by approximately 11.8% and 10.8% in Regions I and II, respectively.

In August 2015, increased both our VC-2 and VC-3 rates by approximately 5.5% in Regions I and II.

As a result of the substantial reductions in VC Rates over the past several years, 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. All-net 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 and Telemar may charge by an average of 0.66% as of October 23, 2010, 1.97% as of December 24, 2011 and 0.55% as of February 8, 2013.2013, 0.65% as of April 18, 2014, and 3.6% as of June 13, 2015. Discounts from the domestic fixed line-to-fixed line long-distance rates approved by ANATEL may be granted to customers without ANATEL approval.

Mobile Long-Distance

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. The applicable VC-2 and VC-3 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-2 and VC-3 rates we are authorized to charge. ANATEL authorized our company and Telemar to increase our VC-2 and VC-3 rates by an average of

0.98% as of February 9, 2010. In November 2011, ANATEL adopted new regulations under which ANATEL was authorized to reduce the then-current VC-2 and VC-3 rates by as much as 18% in 2011, 12% in 2012 and 10% in 2013, after giving effect to an inflation adjustment based on the IST measured from June 2009. In February 2012, ANATEL ordered us to reduce our VC-2 and VC-3 rates by approximately 10%, although we are appealing the timing of the application of these rate decreases to our company as our VC-1, VC-2 and VC-3 rates were increased by 1.54% in Region I in accordance with our application for this increase in February 2012. In March 2013, ANATEL reduced our VC-2 and VC-3 rates in Region I and Region II by approximately 18.6% and 8%, respectively.

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 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.

Under ANATEL regulations, TNL PCS We offer basic service plans (post-paid and Oi Mobile were each requiredpre-paid), as well as non-discriminatory alternatives to submit athe basic post-paid service plan and a basic pre-paid service plan to ANATEL for its approval.plans. As of December 31, 2013,2015, fewer than 1% of our mobile customers subscribed to our basic post-paid plans (post-paid or our basic pre-paid plans.

In addition to the basic service plans, 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, charges for local and long-distance calls and roaming charges) must be submitted for ANATEL approval prior to the offering of those plans to our customers. In general, ANATEL does not raise objections to the terms of these plans. As of December 31, 2013,pre-paid); substantially all of our post-paid and pre-paid customers subscribed to thesenon-discriminatory alternative plans to the basic service plans.

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 six months of such notice.

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.

Rates under our mobile plans may be adjusted annually by no more than the rate of inflation, as measured by the IST.IGP-DI. These rate adjustments occur on the anniversary dates of the approval of the specific plans. Discounts from the rates set in basic service plans and alternative service plans may be granted to customers without ANATEL approval. The rate of inflation as measured by the ISTIGP-DI was 4.90%5.5% in 2011, 4.77%2013, 3.8% in 20122014, and 5.01%10.7% in 2013.2015.

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; and

networks.

other fixed-lineFixed-line service providers for local fixed-line calls that originate on their local fixed-line networks and terminate on our 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. Charges for the use of our local fixed-line networks to terminate local calls originating on the network of another local fixed-line service provider are only billed and due when usage of one of our networks exceeds 55% of the total traffic registered between that network and the network of the other telecommunications service provider.

Since January 1, 2007, the TU-RL rates of Oi and Telemar have been equal to 40% of the rate included in their respective Basic Plan per Minute for a local fixed-line call, which is adjusted on an annual basis by ANATEL. As of the date of this annual report, Oi’s TU-RL rate during peak hours (i.e., between the hours of 9 a.m. and noon and 2 p.m. and 6 p.m. on weekdays) is R$0.035 per minute, and Telemar’s TU-RL rate during peak hours is R$0.032 per minute. ANATEL announced that beginning in 2008, the method used to determine the TU-RL rates would be based on a cost methodology, known as long-run incremental costs. However, in October 2007, ANATEL published an official letter delaying this change until the end of 2010. In September 2010, ANATEL commenced the bidding process to engage an international consultant to assist with the development of the long-run incremental cost methodology. ANATEL has indicated that in the first quarter of 2014 it will announce rates based on a long-run incremental cost methodology that will be applicable beginning in 2016.

In May 2012, ANATEL adopted revisions to the regulations relating to TU-RL rates that became effective in August 2012. Under the revised regulations (1) between August of 2012 and December of 2013, fixed-line service providers will be ablenot 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 only ifnetworks. TU-RL rates vary depending on the outgoing traffic in a given direction of transmission is higher than 75%time of the total traffic between such providers,day and (2) beginning in January 2014, fixed-line service providers will no longer be able to charge other fixed-line service providers for local fixed-line calls originatingday of the week, and are applied on their local fixed-line networks and terminating on the other provider’s local fixed-line networks.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. From January 1, 2007 through July 31, 2012, the TU-RIU rates of Oi and Telemar were equal to 30% of their respective domestic fixed line-to-fixed line long-distance rates for calls of more than 300 km, which are typically adjusted on an annual basis by ANATEL. From August 1, 2012 through December 31, 2012, the TU-RIU rates of Oi and Telemar were equal to 25% of their respective domestic fixed line-to-fixed line long-distance rates for such calls. Since January 1, 2013, 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.See “—Local Fixed-Line Rates—Domestic Long-Distance Rates—Fixed Line-To-Fixed Line.” As

In July 2014, ANATEL approved a rule for the definition of maximum fixed reference rates, including TU-RL and TU-RIU, for entities with significant market power, such as our company, based on a long-run incremental cost methodology. Under this rule, TU-RL and TU-RIU reference rates will decline from 2016 through 2019 when TU-RL and TU-RIU reference rates reflecting the date of this annual report, Oi’s TU-RIU rate is R$0.071 per minute and Telemar’s TU-RIU rate is R$0.075 per minute.long-run incremental cost methodology will apply.

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 VU-M rates, commercial conditions and technical issues, aremay 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 VU-M rates to all requesting service providers on a nondiscriminatory basis. We apply VU-M charges on a per-minute basis.

If we are not able to establish interconnection rates for use of our mobile networks with other mobile and fixed-line telecommunications service providers,Under ANATEL is empowered to arbitrate, at its discretion,regulations, in December 2013 ANATEL established the interconnection rates that we may charge. In January 2010, ANATEL set provisional reference rates for each mobile services provider for each region based on the mean VU-M previously charged by that mobile services provider in the applicable service region. In February 2010, ANATEL authorized an increase of 0.67% in the VU-M rates of our company and Telemar, equivalent to 68.5% of the increase in our VC-1 rates granted at that time.

In November 2011, ANATEL adopted new regulations that provided procedures under which ANATEL adopted a maximum VU-M rate of R$0.33 per minute that is applicable in the event that providers cannotcould not agree upon the VU-M applicable in their interconnection agreements. Under the General Plan on Competition Targets (Plano Geral de Metas de Competição), in February 2014 the VU-M rate was reduced to 75% of the maximum VU-M rate established by ANATEL in December 2013, and in February 2015 will bethe VU-M rate was reduced to 50% of the maximum VU-M rate established by ANATEL in December 2013. In July 2014, ANATEL approved a rule for 2013. Thethe definition of maximum VU-M rate established by ANATEL is R$0.33 per minute.reference rates for entities with significant market power, such as our company, based on a long-run incremental cost methodology. Under this rule, VU-M reference rates will decline from 2016 through 2019 when VU-M reference rates reflecting the long-run incremental cost methodology will apply.

Data Transmission Rates

Broadband services, IP services and frame relay services are deemed to be value-added services under ANATEL regulations and, therefore, the rates and prices for these services are not subject to regulation and are market-driven. 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. We are allowed to increase these rates on an annual basis by no more than the rate of inflation, as measured by the IST. ANATEL also 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 May 2014, ANATEL approved a standard for setting maximum values for EILD services based on a long-run incremental cost methodology. In July 2014, ANATEL published reference rates for EILD services that contain a single reference table which will be valid from 2016 until 2020. Under ANATEL regulations, EILD reference rates will decline from 2016 through 2020 when EILD reference rates reflecting the long-run incremental cost methodology 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 value-addedconditional access services under ANATEL regulations and, therefore,the private regime, which Oi provides pursuant to authorizations. As a result, the rates and prices for these services are not subject to 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 ourOi 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

In 2013,During 2015, we incurred R$556.5406 million in marketing expenses primarily to:

strengthen the “Oi” brand, reinforcing the image of the convergence of the integrated company;

promote our bundled plans, such as “Oi Internet Total,” “Oi Fixo + Oi Velox + Oi TV” and “Fixo Ilimitado + Pré Ilimitado” as part of our effort to expand and strengthen our customer base;

expand our “Oi TV” customer base with offers through our other services;

promotein our pre-paid mobile services throughBrazilian operations. On a promotional campaign that awards prizes to new and existing customers who recharge their Oi SIM cards;

promote our post-paid mobile plans, primarily those that include unlimited calls and 3G data services at higher speeds, through specific marketing campaigns and mobile device subsidies for customers who subscribe to our post-paid plans, as part of our effort to increase our market share in mobile services; and

expand our broadband and 3G internet customer base, focusing on geographic regions covered by the National Broadband Plan.

Throughout 2013,company-wide basis, we focusedfocus our marketing efforts on three typesstrengthening the “Oi” brand, reinforcing the image of customers: (1) retail customers, including mobile telephonethe convergence of the integrated company. We also engage in marketing programs to support our Residential Services, our Personal Mobility Services and residential fixed-line customers; (2) SMEs;our SME and (3) corporate customers.Corporate Services.

We advertise through a diverse array of media outlets as part of our strategy to reach all types and classes of customers and potential customers. We use television, radio, billboards, exterior signage, telemarketing, direct mail and internet advertising to market our fixed-line, mobile, long-distance, broadband and subscription television services. We use our branded fixed assets in advertising campaigns, such as the “Orelhão Mágico” Christmas campaign, in which children are able to “placeplace calls to Santa Claus”Claus from our telephone booths. We also sponsor sporting events and individual athletes, as well as cultural events, such as fashion shows and popular music concerts. We are the official telecom provider and a sponsor of the 2014 World Cup in Brazil. The goal of our marketing initiatives is to increase brand awareness of our company as a convergent provider capable of meeting all of the telecommunications needs of our customers and expand the use of our distribution channels to increase net operating revenue.

Our principal marketing expenditures to support our Residential Services were designed to:

promote our bundled plans, such asOi Total andOi Conta Total as part of our effort to expand our customer base;

promote cross-selling of our services, including by promoting our bundled plans and higher value offers, as part of our effort to increase the profitability and enhance the loyalty of the existing customer base

expand our Oi fixed-line andOi TV customer bases with offers through our other services.

Our principal marketing expenditures to support our Personal Mobility Services were designed to:

promote our pre-paid mobile services via ad campaigns on television and digital media with a focus on our weekly packages and the launch of 4G technology on pre-paid plans;

promote our post-paid mobile plans, primarilyOi Mais andOi Mais Controle, as well as 4G data services at higher speeds, through specific marketing campaigns and mobile device subsidies (through ourOi 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.

In 2015, our SME and Corporate Services business did not engage in any marketing initiatives for its products and services. Instead, our ongoing marketing efforts in our SME and Corporate Services business include:

press releases for launches of new products and services;

client events, including attendance at fairs and conferences; and

other day-to-day marketing.

Distribution Channels

Billing and Collection

Fixed-Line TelephoneResidential Services

We send each of our fixed-lineResidential 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. 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.

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.

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. As of December 31, 2013, 10.3% of all accounts receivable due from our fixed-line customers were outstanding for more than 30 days and 5.0% were outstanding for more than 90 days.

ANATEL regulations permit us to restrict outgoing calls made by a fixed-lineResidential Services customer when the customer’s account is more than 31 days past due, restrict incoming calls received by a fixed-lineResidential Services customer when the customer’s account is more than 61 days past due, and disconnect a fixed-lineResidential Services customer when the customer’s account is more than 91 days past due, provided in each case that 15-days’ prior notice has been given to that customer prior to the imposition of each restriction. The disconnection process thus comprises several stages, including customer notification regarding the referral of their delinquency to credit bureaus, before the fixed-lineResidential 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.

Mobile TelecommunicationsPersonal Mobility Services

We bill our mobile post-paid Personal Mobility Services customers on a monthly basis and itemize charges in the same manner as we bill our fixed-lineResidential Services customers. See “—Fixed-Line Telephone Services.” 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 December 31, 2013, 9.4% of all accounts receivable duepayments from our mobilepost-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 were outstandingas agents for more than 30 days and 4.9% were outstanding for more than 90 days.these banks.

ANATEL regulations permit us to partially suspend services to a mobilepost-paid Personal Mobility Services customer when the customer’s account is more than 15 days past due, restrict all incoming calls received and outgoing calls made by a mobilepost-paid Personal Mobility Services customer when the customer’s account is more than 45 days past due, and cancel services to a mobilepost-paid Personal Mobility Services customer when the customer’s account is more than 90 days past due, provided in each case that 15-days’ prior notice has been given to that customer prior to the imposition of each restriction. The cancellation process thus comprises several stages, including customer notification regarding the referral of their delinquency to credit bureaus, before services to the mobilepost-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 the 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 WiFiWi-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 MSAN equipment to DSLAM equipment as demand for data services increases. As of December 31, 2013,2015, approximately 32.0%90% of our fixed-line network had been updated to support ADSL2+ or VDSL2 and we provided ADSL or VDSL2 services in 4,7034,476 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, Voice over Internet Protocol, or 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 ourOi 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, 2013,2015, our 2G mobile access networks, consisting of 13,62413,777 active radio base stations, covered 1,5043,386 municipalities, in Region I, or 88.2%93% of the urban population in Region I, 1,288 municipalities in Region II, or 96.1% of the urban population in Region II, and 553 municipalities in Region III, or 99.5% of the urban population in Region III.Brazil. We have GPRS coverage in 100% of the localities covered and EDGE coverage in all state capitals.

As of December 31, 2013,2015, our 3G mobile access networks, consisting of 8,3059,265 active radio base stations, covered 4111,288 municipalities, in Region I, or 70.8%79% of the urban population in Region I, 291 municipalities in Region II, or 76.2% of the urban population in Region II, and 189 municipalities in Region III, or 87.0% of the urban population in Region III.Brazil. We have HSPA coverage in all state capitals.

In the fourth quarter of 2012, we began deploying our 2.1 GHz mobile access networks to support 4G service in cities scheduled to host the 2014 World Cup. As of December 31, 2013,2015, our 4G access networks, consisting of 5,213 active radio base stations, covered 24133 municipalities, including the 12 cities hosting the 2014 World Cup, and we expect that they will cover 45 cities by the endor 51% of the second quarterurban population of 2014.Brazil.

In addition to these mobile access networks, we also operate WiFiWi-Fi hotspots in public 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, 2013,2015, our WiFiWi-Fi network consisted of approximately 523,000 hotspots. We have also begun to offerover two million hotspots, with broadband access compatible with approximately 521,000over 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. We 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. We are currently deploying Metro Ethernet networks in additional cities to serve rising customer demand. 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.

Historically, we have used ATM protocol to transport digital signals through our access network from non-residential customers that require dedicated bandwidth to our switching stations. Our ATM networks have a fully-integrated management system and provide:

 

frame relay data services (a data transmission service using fast protocols based on direct use of transmission lines) from 64 Kbps up to 2 Mbps;

 

ATM data services supporting access rates from 2 Mbps to 622 Mbps; and

 

aggregation network services for ADSL2+ platforms.

In response to changing customer needs, we convertingconverted 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 have begun to 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

OurWe have a nationwide long-distance transportation network consistsbackbone, consisting of an optical fiber cable networks supportingnetwork 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. Currently We are inIn 2015, we completed the processimplementation of quadrupling the capacity of our backbone as a result of the deployment of 40 Gbps optical technology. In 2013, we implemented new Optical Transport Network/DWDM, links ofor OTN/DWDM network, with 100 Gbps betweenlinks that connect 11 capitals, including São Paulo, Rio de Janeiro, São Paulo,Brasília and Belo Horizonte and Salvador.Horizonte. This new OTN/DWDM network spreads over approximately 30,000 km of optical cables. Our optical cable network is complemented by microwave links that we use in Region Ito reach smaller cities and Region II. We have a nationwide long-distance backbone, consisting of an optical fiber network that connects the Federal District and the state capitals in Region I and Region II, other than Macapá (located in the State of Amapá) and is complimented by our satellite system. We expect that our optical fiber network will reach Macapá in the first half of 2014. towns.

Most of the large urban areas of Regions I and IIour fixed-line service areas are also connected by our fiber optic cable networks. Our transmission infrastructure connects our digital switches to four international gateway switches: two in Rio de Janeiro, one in Curitiba and one in Brasília.

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 abroad.

We have implemented an address control and name resolution system for our IP networks with the objective of optimizing resources and improving the availability of internet access services.

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, 2013,2015, our satellite network covered approximately 5,165 localities in 2426 states and the Federal District and provided voice and data services to approximately 6.8 million customers.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 Curitiba,and Porto Alegre, Florianópolis, Cuiabá, Porto Velho and Goiânia.Velho. These satellite networks use digital technology and began operating in August 2000. The fiber optic and satellite backbones are interconnected in Brasília, Belém, Fortaleza,Manaus, Rio de Janeiro Curitiba,and Porto Alegre, Florianópolis, Cuiabá, Porto Velho and Goiânia.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 Regions I and II.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 operateoperates the Amazonas 1 satellite,2 and Amazonas 3 satellites, which waswere 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. The Amazonas 1 satellite was launched into geostationary orbit over the Americas and started to operate in November 2004. The Amazonas 1 satellite provides both C and KU band transponders and on-board switching. The Amazonas 1 satellite is owned by a subsidiary of Hispasat and Hispamar has been granted the right to operate and lease all of the transponder space on this satellite.

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.

In 2013, theThe Amazonas 3 satellite was launched to replace all traffic fromand commenced commercial operations in early 2013. The Amazonas 13 satellite was 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 had reachedoperates and leases the end of its useful life.transponder’s entire space segment on this satellite.

We lease transponders from:

 

Hispamar with 754 MHz of capacity, in the C band, on the Amazonas 3 satellite and 540 MHz of capacity in the C band on the Amazonas 2 satellite to provide voice and data services through 653 remote switches covering 390 municipalities;

 

Hispamar with 98.3 Mhz of capacity, in the KU band, on the Amazonas 3 satellite and 576 Mhz of capacity in the KU band on the Amazonas 2 satellite to provide voice and data services to approximately 3,028 localities;

and

 

Intelsat Satellite with 68 MHz of capacity, in the C band, on the IS-905 satellite to transport voice and data signals from Macapá to Rio de Janeiro and Boa Vista to Rio de Janeiro.

As part of our goal to maximize investments and allocate resources to certain strategic developments, in 2015 we focused on the expansion of our backbone infrastructure. We now service more areas through our fixed line infrastructure, which reduced the number of satellites needed to comply with our public service obligations. As a result, we terminated leases and operations for the following satellites:

Intelsat Satellite with 122 MHz of capacity, in the C band, on the IS-805 satellite and 648 MHz of capacity in the C band on the IS 10-02 satellite to transport voice and data signals from Manaus to Rio de Janeiro;

SES New Skies with 1.5 GHz of capacity, in the KU-band, on the SES-6 satellite to provide our own head-end DTH services within Brazil.

In 2005, we and Telemar started to operate gateways satellite platforms operating in the KU band that are comprised of a satellite transport solution with Digital Video Broadcast — Return Channel Satellite, or DVB-RCS, technology and an NGN control solution.

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.

We lease transponders for the delivery of thethese television signals to our subscribers from Telefónica. We have leased 216 Mhz of capacity in the KU band on the Amazonas 13 satellite and 36 Mhz of capacity in the 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 the 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 ourOi TV services.

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, a key priority of the Transformation Plan.

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 Vivo in five municipalities, which we expect to expand during 2016 and succeeding years.

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 Vivo agreed to invest proportionally (50% Vivo, 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.

Network Maintenance

Our external plant and equipment maintenance, installation and network servicing are performed by third-party service providers. We employ our own team of technicians for the maintenance of our internal plant and equipment.

In January 2012, we entered into a services agreement with Telemont 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 State of Rio de Janeiro. In October 2012, we entered into a substantially a similar services agreement with Telemont for installation, operation, and corrective and preventive maintenance in connection with respect toour external plant and associated equipment, public telephones, and fiber optic and data communication networks (including broadband access services) in the States of Minas Gerais, Espírito Santo, Mato Grosso, Mato Grosso do Sul, Tocantins, Acre, Rondônia and Goiás and the Federal District. The total estimated payments during the five-year terms of these contracts are expected to be R$6.6 billion.

In January 2012,October 2015, we entered into a services agreement with Serede Serviços de Rede S/A foracquired all of the operations of Telemont related to our installation, operation, and corrective and preventive maintenance services in connection with our external plant and associated equipment, public telephones, and fiber optic and data communication networks (including broadband access services) in the State of Rio de Janeiro. The total estimated payments under this contract are R$1.4 billion during the five-year term of this contract.

In October 2012, we entered into a services agreement with A.R.M. Engenharia 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, Paraná, and Santa Catarina and Rio Grande do Sul.Catarina. The total estimated payments under this contract are R$6.3 billion during the five-year term of this contract. 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. 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 ARM Engenharia. The completion of the transaction is subject to customary conditions precedent, including the completion of financial and legal due diligence and approval by the Administrative Council for Economic Defense.

FromIn May 2013 toand June 2013, we internalized our installation, operations, and corrective and preventive maintenance services in connection with our fixed-line telecommunications services, mobile telecommunications services, data transmission services (including broadband access services), satellite services, buildings, access ways and towers. These services had previously been provided by Nokia Solutions and Alcatel-Lucent.Alcatel-Lucent Brasil S.A.

CompetitionThrough our wholly-owned subsidiary, Serede, we perform installation, operation, and corrective and preventive maintenance services 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 Rio de Janeiro and Rio Grande do Sul.

OurCompetition

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.”

Local Fixed-LineResidential Services

InWe are the local fixed-line telecommunicationsleading provider of residential services in Regions I and II of Brazil with 14.9 million fixed lines in service (including the number fixed lines provided to our SME and Corporate Services customers) as of December 31, 2015. Based on information available from ANATEL, as of December 31, 2015, we had a market competition has historically been focusedshare of 56.4% of the total fixed lines in service in Region I (including the number fixed lines provided to our SME and Corporate Services customers) and a market share of 52.9% of the total fixed lines in service in Region II (including the number fixed lines provided to our SME and Corporate Services customers). Our principal competitors for fixed-

line services are (1) Embratel, which had a market share of 25.3% of the total fixed lines in service in Region I and a market share of 18.4% of the total fixed lines in service in Region II as of December 31, 2015, based on corporate customers, however, recently our competitors have begun competeinformation available from ANATEL, and (2) GVT, which had a market share of 9.9% of the total fixed lines in service in Region I and a market share of 23.4% of the consumer market with bundles or services targeted to the needstotal fixed lines in service in Region II as of lower income customers. In addition,December 31, 2015, based on information available from ANATEL.

We face competition from other telecommunications services has been increasing,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. Finally, theThe decrease in interconnection rates has discouraged the construction of new fixed-line networks andnetworks. 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 areexpect to continue to face competition from mobile services providers, which represent the leading providermain source of local fixed-line servicescompetition in Regions I and II with 11.6our Residential Services business. As of December 31, 2015, there were 129.3 million fixed lines in servicemobile subscribers (including our mobile customers) in Region I, an 8.9% decrease over December 31, 2014, and 6.7there were 64.0 million fixed lines in servicemobile subscribers (including our mobile customers) in Region II, as ofa 9.6% decrease over December 31, 2013. Based2014, based on the most recent information available from ANATEL,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 of April 30, 2013, we had an estimated market share of 67.8% of the total fixed lines in service in Region Icustomers with both fixed-line and an estimated market share of 62.4% of the total fixed lines in service in Region II. Our principal competitors for fixed-line services are (1) Embratel (a subsidiary of América Móvil), which had an estimated market share of 20.3% of the total fixed lines in service in Region I and an estimated market share of 13.0% of the total fixed lines in service in Region II as of April 30, 2013, based on the most recent information available from ANATEL, and (2) GVT (an affiliate of Vivendi S.A.), which had an estimated market share of 6.9% of the total fixed lines in service in Region I and an estimated market share of 20.7% of the total fixed lines in service in Region II as of April 30, 2013, based on the most recent information available from ANATEL.

mobile telephones use their mobile devices to make calls to other mobile subscribers.

Fixed Line

Embratel provides local fixed-line services to residential customers through fixed devices that receive wireless signals from a single transmission tower located near the subscriber’s residence and through the cable network owned by its subsidiary Net in the portions of Regions I and II where Net provides cable television service. As a result, Net is able to offer cable television, broadband and telephone services as a bundle at a very competitive price. We also expect competition from Embratel to increase in certain large cities such as Rio de Janeiro, Belo Horizonte and Salvador,in our service areas where it continues to expand its localthe volume of demand is attractive.

We also compete in the State of São Paulo with Telefônica Brasil, which is the incumbent fixed-line network.

GVTservice 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 GVTTelefônica Brasil to increase in certain large cities such as Rio de Janeiro, Belo Horizonte and Salvador, and in some medium size cities with population in the range of 350,000 to 1,000,000,our service areas where GVT continues to expand its local fixed-line network.

We expect to continue to face competition from mobile services providers, which represent the main source of competition in the local fixed-line service market. As of December 31, 2013, there were 137.4 million mobile subscribers (including our mobile customers) in Region I, an 3.91% increase over December 31, 2012, and there were 68.3 million mobile subscribers (including our mobile customers) in Region II, a 2.70% increase over December 31, 2012, based on information available from ANATEL. The increase in the number of mobile users, in addition to reduced mobile services rates, is expected to continue to adversely affect the number of fixed-line subscribers and the volume of localdemand is attractive.

Competition from long-distance fixed-line traffic. In addition, because mobileservice providers offer promotions and service plans that permit subscribers to make calls within the mobile provider’s network at rates that are less than those charged for calls from a fixed-line telephone to a mobile telephone, we believe that we may be vulnerable to traffic migrationhas decreased as customers with both fixed-line and mobile telephones use their mobile devices to make calls to other mobile subscribers.

Long-Distance Services

The long-distance services market is highly competitive. As of December 31, 2012, based on the most recent information available from ANATEL, of the total number of national long-distance minutes originated nationwide, we had a market share of 11.0%, ranking behind TIM with 50.1% and Embratel with 27.7% and ahead of Telefônica Brasil with 8.44%.

Our principal competitors for long-distance services are TIM and Embratel, which are currently offering long-distance services throughout Brazil at rates that are charged on a per call, rather than per minute, basis. As a result of our commencement of mobile servicesrecent reductions in Region III, we have also begun to compete with Telefônica Brasil, which is the incumbent fixed-line service provider in Region III.

Increased competition from long-distance service providers has resulted in pressure on our long-distance rates and adversely affected our revenue from these services. In addition, theinterconnections tariffs. The proliferation of new types of service plans, such “same network” subscription plans that offer unlimited long distance calls and data combination plans are impacting the long-distance services market in Brazil. Competition in the 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 domestic market has had and could continue to have a material adverse effect on our revenues and margins.

In addition, the offering ofall-net plans by otherfixed-line and mobile services providers that include free minutes for calls to other subscribers of those mobile services providersany operator have and may continue to adversely impact our revenues from mobilefixed-line long-distance calls if our mobilefixed-line customers choose to migrate to our competitors to remain within the network of the people to whom they plan to placemobile services for long-distance calls. However, as a result of the increased use of SIM card only strategies by other mobile service providers, there is a trend among Brazilian pre-paid customers to purchase SIM cards from multiple mobile service providers to maximize the number of calls that they can make which are covered by these promotional offers.

Newcommunications and/or cancel their fixed-line services. Moreover, new technologies that serve as an alternativealternatives to traditional long-distance telephone calls, such as VoIP may start to captureand instant internet messaging, have captured part of Brazil’s long-distance traffic.

Mobile ServicesBroadband

The mobile telecommunications services market in Brazil is characterized by intense competition among providers of mobile telecommunications services. We compete primarily with the following mobile services providers, each of which provides services throughout Brazil:

Telefônica Brasil, which is a subsidiary of Telefónica S.A, and which markets its mobile services under the brand name “Vivo”;

TIM, which is a subsidiary of Telecom Italia S.p.A.; and

Claro, which is a subsidiary of América Móvil.

In December 2010, Nextel Brazil acquired licenses to provide 3G services throughout Brazil. Nextel launched commercial services on its 3G network in December 2012. Nextel’s entrance in the market could increase competition for mobile services as it expands its network.

As of December 31, 2013, based on information available from ANATEL, we had a market share of 18.5% of the total number of subscribers in Brazil, ranking behind Telefônica Brasil with 28.5%, TIM with 27.1% and Claro with 25.3%, and we captured 10.5% of all net additions of mobile subscribers in Brazil (calculated based on the number of mobile subscribers at the end of a period less the number of mobile subscribers at the beginning of that period) during 2013.

Competitive efforts in the Brazilian mobile telecommunications services market generally take the form of handset subsidies in the post-paid market and traffic subsidies in both the pre-paid and post-paid market. The aggressiveness of promotions is generally driven by the desire of the provider 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.

Data Transmission Services

Cable television providers that offer broadband services, particularly Net and Telefônica Brasil, represent our principal competition in the broadband market. We face competition from these providers thatBoth Embratel 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. Net and Telefônica Brasil offer strong competition for fixed broadband services in municipalities that have the highest concentration of purchasing power.

Our principal competitorsIn 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 commercial data transmission servicesregions in which they operate and often have a market are Embratel, GVT and Telefônica Brasil. The commercial data transmission services market is significantly less regulated than the fixed-line, long-distance and mobile services markets. Along with growth in traffic volume and increasing demand forshare of 20-30% of broadband capacity, we expect significant price reductions in data transmission services as competitors expand their networks. In recent years, there has been a shift in competition towards value-added services provided over IP platforms and VPN services.customers.

Subscription Television ServicesPay-TV

In Brazil, the high quality programming of television broadcasters has resulted in aggregate ratings for these broadcasters of approximately 90%60% of viewers and 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 8.0%approximately 8% of Brazilian households in 2005 to 28.9%approximately 32% in 2013.2015. According to information available from ANATEL, the Brazilian subscription television market grewdecreased by more than 9.8% in from2.1% to 19.1 million subscribers as of December 31, 2012 to2015 from 19.5 million subscribers as of December 31, 2013.2014.

The primary providers of subscription television services in Regions I and IIthe regions in Brazilwhich we provide Residential Services are SKY, which provides DTH services, and América Móvil, which provides DTH service through Embratel under the “Claro TV” brand and

provides subscription television services using coaxial cable through Net. We commenced offeringoffer DTH subscription television services tothroughout the low-income residential marketregions in the states of Rio de Janeiro, Minas Gerais, Rio Grande do Sul, Paraná and Santa Catarina. In 2010,which we expanded this service to the Distrito Federal and the states of Bahia, Sergipe, Pernambuco, Ceará, Paraíba, Rio Grande do Norte, Alagoas, Espírito Santo and Goiás. In 2011, we expanded this service to the remaining states of Regions I and II.provide Residential Services.

In December 2012 and January 2013, we began toWe deliverOi TV through our fiber optic network using an internet protocol, or IP TV, in the cities of Rio de Janeiro and Belo Horizonte, respectively.

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, 2015, based on information available from ANATEL (which includes SME and Corporate Services subscribers), we had a market share of 18.6% of the total number of mobile subscribers in Brazil, ranking behind Telefônica Brasil with 28.4%, TIM with 25.7% and Claro with 25.6%. As of December 31, 2015, based on information available from ANATEL, the competitive landscape for mobile services was as follows: in Region I, we had a market share of 24.3% of the total number of mobile subscribers, ahead of Telefônica Brasil and behind TIM with 25.1% and Claro with 24.7%; in Region II, we had a market share of 14.4% of the total number of mobile subscribers, ranking behind Telefônica Brasil with 32.0%, TIM with 26.8% and Claro with 26.7%; and in Region III, we had a market share of 12.2% of the total number of mobile subscribers, ranking behind Telefônica Brasil with 33.1%, Claro with 26.1% and TIM with 25.7%.

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 theOi 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 theOi Mais,Oi Mais Controle andOi 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, 2015, our Wi-Fi network consisted of over two million hotspots, with broadband access compatible with over 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.

Following a study of the telecommunications consumption habits in Brazil, in November 2015 we launched ourOi Livre portfolio, a set of innovative offerings with significant increase in data allowances and a flat fee for all-net calls (with the exception ofOi Livre Por Dia) to customers of any operator in Brazil. This initiative changes the mobile service market in Brazil and the manner in which our customers communicate, disrupting the original pre-paid model in which customers acquired SIM cards from different operators and used the respective SIM for on-net calls with that particular operator in an effort to avoid paying high rates for off-net calls.

In the post-paid mobile data communications market, our primary competitors are Telefônica Brasil, Claro and TIM. As of December 31, 2015, based on information available from ANATEL, which includes SME and Corporate Services subscribers, we had a market share of 11.9% of the total number of post-paid mobile data subscribers in Brazil (including hybrid data plan subscribers), ranking behind Telefônica Brasil with 42.4%, Claro with 22.7% and TIM with 18.5%. 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, Vivo 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, 2015, based on information available from ANATEL, which includes SME and Corporate Services subscribers, we had a market share of 21.3% of the total number of pre-paid mobile data subscribers in Brazil, ranking behind Telefônica Brasil with 22.9%, Claro with 26.7% and TIM with 28.5%. 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 offer plans similar toOi Livre.

Competition in Mobile Long-Distance Services

Recent reductions in the interconnections rates for Regions I, II and III have resulted in lower costs for long-distance services, both to gradually expandus and to our IP TVcustomers. As a result, we and TIM have introduced “all-net” voice and messaging plans that allow customers to call anywhere in Brazil for a flat rate. Nearly all the plans in our recently launchedOi Mais,Oi Mais Controle andOi Livre portfolios offer all-net calling and text messaging services, which capitalized on the reductions in interconnection rates and simplified our portfolios, thereby eliminating the community effect. We believe that the introduction of all-net plans, coupled with more robust and data packages that allow consumers to use smartphones applications more freely, have substantially reduced competition in the mobile long-distance services market.

SME and Corporate 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 SME and corporate services providers toward value-added services. With the exception of theOi Mais Empresas app and web service, our value-added products and services for the SME segment are substantially similar to other cities.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 Embratel, 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.

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;

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;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, while allowing us to apply the amount of such fees to finance the expanded service obligations created by the amended General Plan on Universal Service Goals in lieu of making payment to ANATEL;

requires us to pay fines for systemic service interruptions; and

requires us to rescind our contracts if ANATEL determines they are contrary to any rules or regulations, economic order or public interest.

These concession agreements also required 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 were 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.

Domestic Long-Distance Services Concession Agreements

We have entered into concession agreements with ANATEL that govern our concessionsCommunications and telecommunications service providers met regularly to provide domestic long-distance services originating from the Federal District anddiscuss possible amendments to each of the statesconcession agreements granted by ANATEL, including ours, and the implications of Regions Ithe developments and II. Eachdemands in the telecommunications sector in recent years. In September 2015, the Ministry of Communications created a working group, consisting of three members from each of ANATEL and the Ministry of Communications, to evaluate the status of the concessions and propose guidelines for the amendment of the concession agreements. In November 2015, the Ministry of Communications opened public consultation on the new regulatory framework for telecommunications. The Ministry of Communications has extended the deadline for contributions on multiple occasions. In April 2016, the Ministry of Communications, based on the working group’s findings, issued a decree addressing guidelines for the establishment of a new regulatory framework for telecommunications, which will be implemented by ANATEL through the conclusion of the concession amendments. 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. As a result of the publication of these guidelines, ANATEL requested a further postponement of the review of our concession agreements:

We willare also be 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 have 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 hashave executed cooperation agreements with the following national research centers: CERTI Foundation, C.E.S.A.R., 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), Technological Innovation Foundation (Fundação Para Inovações TecnológicasFITEC), National Institute for Telecommunications Foundation (Fundação Instituto Nacional de Telecomunicações—Inatel)

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 2011,2015, we intensified the process for the exploration of innovative services and activities concerning innovation, research and development to promote our innovation ecosystem and in October 2011 launched the first call for Innovative Mobile Applications for Major Events through the Oi Innovation Program (Programa Oi Inovação).ecosystem.

Our investments in innovation, research and development totaled R$20 million in 2015, R$16 million in 2014 and R$13 million in 2013, R$11 million in 2012 and R$23 million in 2011.2013.

Pharol, our subsidiaries PT Ventures and Africatel GmbH & Co KG, of 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.

On September 16, 2014, our subsidiary, Africatel GmbH, which directly holds our interest in Africatel, received a letter from Samba Luxco in which 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 the letter, Samba Luxco purported to exercise the alleged put right and thereby require Africatel GmbH to acquire its shares in Africatel.

On September 26, 2014, Africatel GmbH responded to Samba Luxco stating that there had not been any action or event that would trigger the right to exercise the put option under the Africatel’s shareholders’ agreement and that Africatel GmbH intended to challenge Samba Luxco’s purported exercise of the put option. On the same date, we issued a Material Fact disclosing Samba Luxco’s purported exercise of the put option, our understanding that the exercise of the put option is not applicable, and that our board of directors had authorized our management to take the necessary actions to sell our interest in Africatel.

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 other rights and claims allegedly arising out of Oi’s acquisition of PT Portugal. Africatel GmbH presented its answer to Samba Luxco’s request for arbitration on December 15, 2014. The arbitral tribunal was constituted on March 12, 2015 and the proceedings are ongoing. Africatel GmbH intends to continue to vigorously defend these proceedings.

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 have an 18.75% economic interest in Unitel. We account for this investment as an asset held-for-sale.

MTC, Namibia

In 2006, Pharol entered into an agreement to acquire 34% of the capital of MTC, a Namibian mobile operator, from Namibia Post and Telecom Holdings, a state-controlled entity, or NPTH. In connection with this transaction, Pharol entered into a shareholders’ agreement with NPTH regarding governance and liquidity rights relating to MTC that allowed Pharol to set and control the financial and operating policies of MTC. In 2006, Pharol assigned its rights to acquire the capital of MTC and its rights under the shareholders’ agreement 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 fully consolidate MTC in our consolidated financial statements.

As of December 31, 2015, MTC had 2.4 million customers, of which 93.7% were customers under pre-paid plans.

MTC was established in 1994 and provides mobile telecommunications services under the terms of a 15-year technology- and service-neutral concession granted in March 2012 that replaced its earlier licenses. Under the terms of this concession, MTC is permitted to offer 2G, 3G and 4G services. MTC commenced offering 4G services in Windhoek, the capital of Namibia, in May 2012 and, R$as of December 31, million2015, MTC provided 4G services to 65% of cities in 2011.Namibia.

In 2006, a license was granted to Powercom to provide mobile telecommunications services in Namibia. Powercom commenced operations in 2007. In November 2012, Telecom Namibia, the incumbent provider of fixed-line telecommunications services in Namibia and a wholly-owned subsidiary of NPTH, acquired Powercom. Telecom Namibia re-launched Powercom’s portfolio of service plans under the brand “TN Mobile” in August 2013. In November 2013, TN Mobile began offering 4G services in Windhoek and other urban areas.

During 2015, MTC focused its marketing efforts and commercial activity on selling new pre-paid plans with increased data packages in an effort to differentiation itself from its competitors and promoting the upselling of new pricing plans aimed at increasing usage and revenues.

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, we were only able to elect three of the seven members of the board of directors of CVTelecom. In March 2015, we commenced arbitration proceedings disputing this interpretation of the shareholders’ agreement, and we intend to vigorously defend our rights under the shareholders’ agreement. We are currently engaged in negotiations with the other shareholder of CVTelecom to seek an alternative resolution of this dispute. As a result of this dispute, for dates and periods ending after January 1, 2015, we have recorded our interest in CVTelecom under the equity method.

As of December 31, 2015, CVTelecom had approximately 54,200 fixed-lines in service, which represents approximately 10.6 fixed main lines per 100 inhabitants. As of December 31, 2015, CVTelecom had approximately 404,000 active mobile telephone cards.

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.

During 2014, CVTelecom launched several commercial offers, both mobile and fixed lines, aimed at promoting usage and customer loyalty, including: (1) the development of a youth segment, based on the “Powa Swag” service, (2) the launch of several voice promotions, such as “Di Borla Domingão,” and (3) the development of “ZAP,” an NPlay offer. As of December 31, 2015, broadband and IPTV customers represented 28.2% and 10.9% of CVTelecom’s fixed line customer base, respectively.

CST, São Tomé and Principe

Africatel owns 51.0% of the share capital of CST, which provides fixed and mobile services in São Tomé and Principe. As of December 31, 2015, CST had approximately 155,300 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 to 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.

During 2015, CST worked on several initiatives designed to promote its commercial brand and customer loyalty in order to mitigate the effects of the new competitor. In addition, CST also launched a new data link between the islands of São Tomé and Principe, which increased the capacity more than nine times compare to the previous link connecting the two islands.

Regulation of the Brazilian Telecommunications Industry

Overview

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 and mobile telecommunications 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 theRegulamento 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

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, Telesp,Telefônica Brasil, Embratel 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 quality of service, continuity and universality of service, network expansion and network modernization. Additionally, the rates that public regime service providers may charge customers are subject to ANATEL supervision.

Providers Another distinctive feature of private regime services, although not generally subjectpublic concessions is the right of the concessionaire to maintain certain economic and financial standards, which are calculated based on the requirements concerning continuity and universality of service and network modernization, are subject to certain network expansion and quality of service obligationsrules set forth in their respective authorizations.

Regulation of Fixed-Line Services

General Policies for the Regulation of the Fixed-Line Telecommunications Sector

In June 2003, Brazil’s president issued Decree No. 4,733, outlining a number of new rules and guidelines which were intended to consolidate several changes in the regulation of Brazil’s fixed-line telecommunications sector. This decree sets forth general declarations of policy regarding, among other things:

universal access to telecommunications services;

stimulation of employment and development of the Brazilian telecommunications sector;

promotion of competition and adoption of rate readjustment policies that take into account Brazilian socioeconomic considerations; and

the financial equilibrium of existing concession agreements.

This decree also defined certain changes that are reflected in theour concession agreements entered into by providersand was designed based on a price cap model. The concessions are granted for a fixed period of public regime services that became effective on January 1, 2006.time and are generally renewable only once.

A number of bills affecting telecommunications policy have been submitted to the Brazilian Congress with an aim to make telecommunications services more accessible to Brazil’s low-income population. These bills have proposed to eliminate the monthly subscription fee(assinatura mensal) that compensates telecommunications companies for extending and maintaining fixed-line telecommunications services for their customers. If approved, we expect that this proposal will adversely affect the overall margin of telecommunications providers, including us. For a discussion of the legal and regulatory risks associated with our business, see “Item 3. Key Information—Risk Factors—Risks Relating to Our Company and the Brazilian Telecommunications Industry—Our industry is highly regulated. Changes in laws and regulations may adversely impact our business.”

Private Regime Authorizations

With the goal of introducing competition in fixed-line telephone services in Brazil, the federal government granted four private-regime authorizations in 1999 to permit fixed-line service providers to compete with the incumbent fixed-line concessionaires. Since 2002, the number of authorizations to provide fixed-line services that the federal government may issue is unlimited.

Public Regime Concessions

Each of the public regime service providers operates under concession agreements that expire in December 2025. Under these concession agreements, each of the public regime service providers is required to comply with the provisions of (1) the General Plan on Universal Service that was adopted by ANATEL in June 2003, (2) the General Plan on Quality Goals that was adopted by ANATEL in June 2003, and (3) the General Plan on Competition Targets (Plano Geral de Metas de Competição) that was adopted by ANATEL in November 2012.

The 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 2015 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. We submitted our comments during this period. 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 Ministry of Communications created a working group, consisting of three members from each of ANATEL and the Ministry of Communications, to evaluate the status of the concessions and propose guidelines for the amendment of the concession agreements. In November 2015, the Ministry of Communications opened public consultation on the new regulatory framework for telecommunications. The Ministry of Communications has extended the deadline for contributions on multiple occasions. In April 2016, the Ministry of Communications, based on the working group’s findings, issued a decree addressing guidelines for the establishment of a new regulatory framework for telecommunications, which will be implemented by ANATEL through the conclusion of the concession amendments. 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. As a result of the publication of these guidelines, ANATEL requested a further postponement of the review of our concession agreements, which was granted. As a result of this extension, the review of our concession agreements is currently scheduled to occur by December 2016.

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 2003, (2) the General Plan on Quality Goals that was adopted by ANATEL in June 2003, 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

PublicUnder the concession agreements, public regime service providers mustare required to offer a basic service plan comprised of the following basic services: (1) installation; (2) monthly subscription; and (3) switched local minutes. Modifications of the rates charged for these basic services are determined by referencefixed-line plans to a local rate basket that represents the weighted average of the rates for

monthly subscriptions and switched local minutes.users. Rates for long-distance services originated and terminated on fixed lines vary in accordance with three basic criteria: (1) physical distance separating callers; (2) time of the day; and (3) day of the week on which the call is placed. Modifications of the rates charged for these long-distance services are determined by reference to a long-distance rate basket that represents the weighted average of the rates for long-distance calls. The rates for the provision of services through payphones and installation rates are treated separately. The rates for international long-distance services provided by Embratel, the incumbent international long-distance concessionaire, are regulated by ANATEL. However, the rates for international long-distance services charged by other long-distance service providers, all of whom provide these services under authorizations rather than concessions, are not subject to ANATEL regulation.

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.

Prior to 2008, Factor X, which was discounted from the IST, was equal to 50% of the increase in a public regime provider’s productivity. Beginning in 2008, 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. These regulations were submitted forANATEL expected to launch a public consultation in July 2011 and the public consultation period ended on September 1, 2011. We expectprocess relating to these newproposed regulations as they may be modified as a result of ANATEL’s further analysis, to be adopted in 2014.during 2016.

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 was approved by ANATEL in June 2003 and became effective in January 2006.2011. The General Plan on Universal Service Goals sets forth the principal network expansion and modernization obligations of the public regime providers, such as providing public telephones in localities with a population in excess of 100, and installing residential fixed lines within seven days of a request in localities with a population in excess of 300. In addition, public regime providers must comply with the Special Individual Access Class (Acesso Individual Classe Especial) rules, which are designed to require service for economically disadvantaged people. Under the Special Individual Access Class rules, a qualifying customer may subscribe to a service plan, limited to one fixed-line per household, and pay a lower monthly fee for service than under the basic service plans.providers.

Public regime providers are also 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.

On June 30, 2011, theThe General Plan on Universal Service was amended. AmongGoals, as amended, requires the following, among other things, these amendments:things:

 

expanded the obligations of 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;

 

reduced the density requirements applicable to the obligations of local fixed-line service providers to provide public telephones in urban areas within their service areas;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

 

expanded the obligations to provide universal service in rural and remote areas of local and long-distance fixed-line providers that obtain authorizations to use radio spectrum in the 450 Mhz band including increased obligationsto provide universal service in rural and remote areas, as well as to provide individual and group access to fixed-line voice services.

The General Plan on Universal Service Goals is expected to be amended again in 2016 In connection with the amendments to the concession agreements.

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, the Brazilian congress passed Law No. 12,485 became effective, which was signed into law by the President of Brazil in September 2011. Law No. 12,485 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 is expected to increaseincreased the availability and lower the price of subscription television services in Brazil, through increased competition among providers, and improve 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. AlthoughIn September 2014, we have not yet signed theentered into a Conditional Access Service authorization agreement the act by whichwith ANATEL granted our requestthat authorized us to begin offeringoffer the services to be governed by such agreement, including IP TV.

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;

 

failure to meet insurance requirements set forth in the concession agreement;

 

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.

General Plan on Quality Goals

The General Plan on Quality Goals was approved by ANATEL in June 2003 and became effective in January 2006. 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;

 

operator availability;

 

availability of services to customers;

personal services to customers;

 

issuance of bills;

 

responses to mail received from customers; 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. Additionally, they are obligated to provide ANATEL with an in-depth report and analysis on each quality goal that is not satisfied. ANATEL may also collect such data from fixed-line service providers at any time without prior notice. Fixed-line service providers that fail to meet quality goals established by ANATEL may be subject to warnings, fines, intervention by ANATEL, temporary suspensions of service or cancellation of their concessions and authorizations.

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.

Our failure to meet the quality of service obligations established by the General Plan on Quality Goals or in our concession agreements may result in fines and penalties of up to R$40 million.

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.

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 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. The methodology by which the wholesale prices for these services will be determined will be established by ANATEL. We expect that ANATEL will commence a public consultation process with respect thereto in 2014.during the second half of 2016.

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 VU-M rate). The General Plan on Competition Targets established a reference value for VU-M rates of providers that are deemed to hold significant market power and determined that beginning in 2016, VU-M rates will be determined on the basis of costs. In July 2014, ANATEL approved a rule for the definition of maximum VU-M reference rates for entities with significant market power, such as our company, based on a long-run incremental cost methodology. Under this rule, VU-M reference rates will decline from 2016 through 2019 when VU-M reference rates reflecting the long-run incremental cost methodology will apply.

The General Plan on Competition Targets established that the VU-M would be paid only when the traffic out of a network in a given direction was greater than (1) 80% of the total traffic exchanged until February 23, 2015, and (2) 60% of the total traffic exchanged from February 24, 2015 to February 23, 2016. After February 24, 2016, each mobile service provider would be entitled to collect the VU-M 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:

until February 2015, mobile service providersTargets regulation relating to the VU-M applicable to the relationship between companies with significant market power will be able to charge service providersand companies without significant market power for calls originating from or terminating on theirpower. Under the revised regulations, the dates and percentages applicable to the VU-M partial bill-and-keep system were revised so that the VU-M will be paid only when the traffic out of a network only if the outgoing traffic in a given direction of transmission is higher than 80%greater than:

75% of the total traffic between such providers;

Roaming

Under the General Plan on Competition Targets, a mobile service provider with significant market power, such as our company, must offer roaming services to other mobile providers without significant market power at the maximum rate that the mobile service provider with significant market offerspower is permitting ANATEL to offer such services to its retail customers.

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.

Under the personal mobile service regulations:

Band A and Band B service providers can apply for an additional frequency range;

each service provider may apply to provide domestic and international long-distance services originating from its service region;

existing service providers, as well as new entrants into the Brazilian telecommunications market, may bid for new licenses in all frequency bands, other than Band A and Band B;

personal mobile services providers are required to offer a basic service plan to their customers containing certain prescribed features;

personal mobile services providers are required to establish interconnection rates for the use of one provider’s network by another provider;

the number of regions in which a personal mobile services provider may offer services is not limited; and

a personal mobile services provider, or its controlling shareholders, may not hold more than one personal mobile services authorization covering any specific region.

Auction of Personal Mobile Services Spectrum

Prior to the establishment of the personal mobile services regime, ANATEL had granted licenses to mobile services providers to operate in each region of Brazil using Bands A and B. In 2001 and 2002, ANATEL successfully auctioned authorizations and licenses to operators in Band D and Band E in each region. TNL PCS was granted its initial authorization to provide personal mobile services in Region I and a license to operate in Band D in March 2001. We were granted our initial authorization to provide personal mobile services in Region II and a license to operate in Band E in December 2002.

ANATEL conducted additional auctions of radio frequency licenses in 2004 and 2006. In April 2004, we acquired an additional license to operate in Region II.

In December 2007, ANATEL auctioned the remaining spectrum of Bands A, B, C, D and E to existing service providers as extension blocks and auctioned additional spectrum in Band M (1.8 GHz) and Band L (1.9 GHz). In these auctions, TNL PCS acquired (1) an authorization to provide personal mobile services in the State of São Paulo and licenses to operate using Band M throughout the State of São Paulo and Band E outside of the city of São Paulo and (2) licenses to use additional spectrum in 12 states in Region I.

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 450MHz Band and 2.5 GHz Band

Under Executive Decree 7,512, dated June 30, 2011, or Executive Decree 7,512, ANATEL granted authorizations to telecommunications providers to use radio spectrum inIn preparation for auctions of the 450 Mhz450MHz band radio spectrum and the 2.5 GHz radio spectrum,band, the latteruse of which allows telecommunicationspersonal mobile services providers to offer 4G services to their customers. Among other obligations, licenseescustomers, ANATEL issued regulations that divided the Brazilian territory into three regions for purposes of radio frequencies in the 450 Mhz band radio spectrum must agree to provide individual and collective voice and data services in rural and remote areas, in accordance with the provisions of Executive Decree 7,512 and the General Plan on Universal Service.providing personal mobile services. In June 2012, we acquiredANATEL auctioned radio frequency licenses necessary to offer 4Goperate 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 5,564 municipalities in Regions I, IIthe States of Goiás, Mato Grosso, Mato Grosso do Sul, Rio Grande do Sul and III.

Personal Mobile Services Rate Regulation

Ratesthe Federal District, and (2) 11 regional lots for 2.5 GHz bands to provide personal mobile services are regulatedin 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 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). ANATEL is currently reviewing whether the obligations that should have been met by ANATEL. Personal mobile services providers are requiredthe end of 2015, as set out in the auction for the 2.5 GHz and 450 MHz frequencies have been met. 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 offer a basic service plan that consists of a monthly subscription, local calls and roaming. Basic service plans were approved by ANATEL for each of thesupport personal mobile services providers following(voice and broadband) in the grant of personal mobile services authorizations2.5 GHz band, among others, in order to each of these providers.

Following the effectiveness of the basic service plans, annual adjustments of the rates under these plans have been subject to a price cap mechanism. Through 2005, rates were adjusted annually by no more than the rate of inflation, as measured by the IGP-DI. In 2006, ANATEL replaced the IGP-DIensure compliance with the ISTscope of commitments between 2015 and 2017 and the expansion of 4G coverage in municipalities with a population over 30,000. ANATEL rejected the proposal to calculate annual rate adjustments.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.

Personal mobile services providers are permitted to offer non-discriminatory alternative plans to the basic service plan. The rates charged under these plans (e.g., monthly subscription rates, charges for local calls and roaming charges) are subject to ANATEL approval prior to the time that these plans are first offered to mobile customers. Following the approval of these plans, the rates under these plans may be increased up to an annual adjustment that is approved by ANATEL and is no more than the rate of inflation, as measured by the IST.

Although subscribers of a plan cannot be forced to migrate to new plans, existing plans may be discontinued as long as all subscribers receive a notice to that effect and are allowed to migrate to new plans within six months of such notice. Discounts from the rates set in basic service plans and alternative service plans may be granted to customers without ANATEL approval.

In November 2012, ANATEL adopted revisions to the personal mobile services regulations that became effective in February 2013. Under these revised regulations, successive telephone calls originating from one telephone number to the same prior destination are considered one single call if the time elapsed between calls is equal to or less than 120 seconds, regardless of the duration of each individual call.

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.

Network Expansion Obligations

The personal mobile services authorizations set forth certain obligations and targets that must be met by a personal mobile services provider. For a description of the obligations and targets that must be met by our company, see “—Concessions, Authorizations and Licenses—Personal Mobile Services Authorization Agreements and Radio Frequency Spectrum Licenses” and “—Concessions, Authorizations and Licenses—3G Radio Frequency Licenses.”

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 thesethis quality of service standards, and we must report information in connection with such standards to ANATEL.

Additional Obligations

In August 2007,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 adopted revisionsapproved 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 personal mobile services regulations that became effective in February 2008. These revised regulations imposed additional obligations on personal mobile services providers, particularly in connection with customers’ rights. These obligations require personal mobile services providers to:definitions of the Resolution 575/2011.

establish at least one customer service center in each registration area served that has more than 100,000 inhabitants;

upgrade customer service centers to improve access by people with hearing disabilities;

increase the term applicable to pre-paid cards from 90 days to 180 days or more;

deliver to pre-paid customers a detailed report of service use upon request;

reimburse unused pre-paid credits;

limit the duration of contracts with pre-paid customers to 12 months;

permit customers to change service plans without penalties; and

unblock mobile handsets, allowing a customer who purchased a mobile handset from any personal mobile services provider to use it on the network of another personal mobile services provider.

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 initiallyhas adopted General Rules on Interconnection (Regulamento Geral de Interconexão) in 1998, which were amended and restated in July 2005.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 ratescalls are adjusted.

Fixed-lineUnder ANATEL regulations, fixed-line service providers are only required to pay interconnection fees to another fixed-line service provider for traffic in the same local area in the event that the ratio of the outbound traffic generated by that provider (measured in minutes) to the inbound traffic terminated by that provider (measured in minutes) exceeds 75% or was less than 25%. This system is designated the “partial bill-and-keep” system.

In 2006, ANATEL established that (1) the TU-RL rates that fixed-line service providers could charge each other to terminate a call on their respective networks was 50% of the rate included in their Basic Plan per Minute for a local fixed-line call, and (2) the TU-RIU rates that fixed-line service providers could charge each other to use a portion of their long-distance networks to complete long-distance calls was 30% of the applicable domestic fixed line-to-fixed line long-distance rates for calls of more than 300 km. In 2007, the TU-RL rates of the fixed-line service providers were reduced to 40% of the rate included in their Basic Plan per Minute for a local fixed-line call.

ANATEL announced that beginning in 2008, the method used to determine the TU-RL rates would be based on a cost methodology, known as long-run incremental costs. However, in October 2007, ANATEL published an official letter delaying this change until the end of 2010. In September 2010, ANATEL commenced the bidding process to engage an international consultant to assist with the development of the long-run incremental cost methodology. ANATEL has indicated that in the first quarter of 2014 it will announce rates based on a long-run incremental cost methodology that will be applicable beginning in 2016.

In May 2012, ANATEL adopted revisions to the regulations relating to TU-RL rates and TU-RIU rates that became effective in August 2012. Under the revised regulations (1) between August of 2012 and December of 2013, fixed-line service providers will be 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 only if the outgoing traffic in a given direction of transmission is higher than 75% of the total traffic between such providers, and (2) beginning in January 2014, fixed-line service providers were no longer benot 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 August 2012, the TU-RIU rates were reduced to 25% of the applicable domestic fixed line rates for calls with more than 300 km, and in January 2013, TU-RIU rates were reduced to 20% of the applicable domestic fixed line rates for such calls.

In July 2014, ANATEL approved a rule for the definition of maximum fixed reference rates, including TU-RL and TU-RIU, for entities with significant market power, such as our company, based on a long-run incremental cost methodology. Under this rule, TU-RL and TU-RIU reference rates will decline from 2016 through 2019 when TU-RL and TU-RIU reference rates reflecting the long-run incremental cost methodology will apply.

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 VU-M 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 VU-M rate to all requesting providers on a nondiscriminatory basis. Interconnection agreements must be approved by ANATEL before they become effective and they 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 VU-M rates when we began offering personal mobile services, ANATEL set the initial VU-M rates.

Personal mobile services providers negotiate annual rate increases for their VU-M 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 November 2011,Under ANATEL adopted new regulations, under which ANATEL was authorized to reduce the then-current VC-1, VC-2 and VC-3 rates by as much as 18% in 2011, 12% in 2012 and 10% in 2013, after giving effect to an inflation adjustment based on the IST measured from June 2009. In February 2012, ANATEL ordered us to reduce our VC-1, VC-2 and VC-3 rates by approximately 10%, although we are appealing the timing of the application of this rate decrease to our company as our VC-1 rate was increased in Region I by 1.54% in accordance with our application for this increase in February 2012. In MarchDecember 2013 ANATEL reduced our VC-1 rates in Region I and Region II by approximately 18.6% and 8%, respectively. These regulations also provided procedures under which ANATEL adopted aestablished the maximum VU-M rate of R$0.33 per minute that is applicable in the event that providers cannotcould not agree upon the VU-M applicable in their interconnection agreements. Under the General Plan on Competition Targets, in February 2014 the VU-M rate was reduced to 75% of the maximum VU-M rate established by ANATEL in December 2013, and in February 2015 will bethe VU-M rate was reduced to 50% of the maximum VU-M rate established by ANATEL in December 2013. In July 2014, ANATEL approved a rule for 2013. Thethe definition of maximum VU-M rate established byreference rates for entities with significant market power, such as our company, based on a long-run incremental cost methodology. Under this rule, VU-M reference rates will decline from 2016 through 2019 when VU-M reference rates reflecting the long-run incremental cost methodology will apply.

Consumer Protection Regulation

In March 2014, ANATEL is R$0.33 per minute.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.

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. In March 2007, ANATEL adopted theANATEL’s General Regulation of Portability (Regulamento Geral de Portabilidade), establishing 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. Service providers are permitted to charge a migrating customer that elects to retain its telephone number a one-time fee of no more than R$4.00. This amount is intended to compensate the customer’s current provider for the costs associated with managing the portability process. The new provider may elect to absorb this fee on behalf of the customer.

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. Following publication of these forms of agreement, the rates under these agreements may be increased on an annual basis by no more than the rate of inflation, as measured by the IST. ANATEL also 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 May 2014, ANATEL approved a standard for setting maximum values for EILD services based on a long-run incremental cost methodology. Reference rates for EILD services were published containing a single reference table which will be valid from 2016 until 2020. Under this ANATEL regulation, EILD reference rates will decline from 2016 through 2020 when EILD reference rates reflecting the long-run incremental cost methodology 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 the Regulations,such regulations, including:

 

individual upload and download speeds of at least 20%, 30% and 40% of contracted speeds per measurement for at least 95% of all measurements, during the first year, second year and thereafter, respectively, following implementation of the Regulations;

measurements;

 

average upload and download speeds of at least 60%, 70% and 80% of contracted speeds for all measurements during the first year, second yearmeasurements; and thereafter, respectively, following implementation of the Regulations; 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 the Regulations.such regulations. Failure to meet such standards will subject non-compliant service providers to sanctions. We have met these standards for 2013.

National Broadband Plan

On June 30, 2011, we entered into a Term of Commitment (Termo de Compromisso) with ANATEL and the 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 Region 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 Region 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 arehave been obligated to provide the maximum capacities established by the Term of Commitment to eligible wholesale customers bysince 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 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 by 2015.

municipalities.

The Term of Commitment will expire on December 31, 2016.

Legal Framework for the Use of the Internet (Internet Bill of Rights)

In April 2014, 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.

Other Regulatory Matters

Regulatory Agenda 2015-2016

On June 29, 2015, ANATEL put in public consultation its proposed Regulatory Agenda for the 2015-2016 cycle, and revocation of the General Plan of the Telecommunication Regulatory Update in Brazil (PGR). The agenda contained 33 topics of interest to the sector, which should have final approval or some progress in 2015 and 2016. The listed items include: Civil Rights Framework for Internet, 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, review of the regulation of the SeAC (Serviço de Acesso Condicionado) and review of regulatory reversible assets.

New Regulatory Framework

On November 23, 2015, the Ministry of Communications opened public consultation on the new regulatory framework for telecommunications. The consultation is based on a series of questions under four basic axes: purpose of the public policy, universal policy, public regime versus the private regime and public concession. The Ministry of Communications has extended the deadline for contributions on multiple occasions. In April 2016, the Ministry of Communications issued a decree addressing guidelines for the establishment of a new regulatory framework for telecommunications, which will be implemented by ANATEL through the conclusion of the concession amendments. 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. As a result of the publication of these guidelines, ANATEL requested a further postponement of the review of our concession agreements, which was granted. As a result of this extension, the review of our concession agreements is currently scheduled to occur by December 2016.

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 andor 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.

Proposed Business Combination

On October 1, 2013, we entered into a memorandum of understanding, or the MOU, with Portugal Telecom, AG Telecom, LF Tel, PASA, EDSP, Bratel Brasil, BES and Ongoing, in which we and they agreed to the principles governing a series of transactions, including the business combination described below.

The business combination transaction involves three principal components:

a capital increase of our company in which we expect to issue common shares and preferred shares in an underwritten offering for an aggregate of at least R$7,0008,250 million in cash, and (2) 104,580,393 of our common shares and 172,025,273 of our preferred shares to Portugal TelecomPharol in exchange for the contribution by Portugal TelecomPharol to our company of all of the shares of its subsidiary PT Portugal. PT Portugal which will at that time owns (a)provides a broad range of telecommunications services in Portugal and owned significant interests in telecommunications companies in Angola, Cape Verde, Namibia, and São Tomé and Principe in Africa and Timor-Leste in Asia.

Disposition of PT Portugal

On June 2, 2015, we sold all of the operating assetsshare capital of PT Portugal Telecom, except interests held directly or indirectlyto 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 Oithe event

that the consolidated revenues of PT Portugal and Contax Holding, and (b) all of Portugal Telecom’s liabilities at the timeits subsidiaries (as of the contribution, which we referclosing date) for any single year between the year ending December 31, 2015 and the year ending December 31, 2019 is equal to collectively as the Oi capital increase;or exceeds €2,750 million.

a merger of shares (incorporação de ações) under Brazilian law, a Brazilian transaction in which, subject to the approvals of the holders of voting shares of our company and TmarPart, all of the shares of our company not owned by TmarPart will be exchanged for TmarPart common shares and we will become a wholly-owned subsidiary of TmarPart; and

a merger (incorporação) under Portuguese and Brazilian law, of Portugal Telecom with and into TmarPart, with TmarPart as the surviving company in which the shareholders of Portugal Telecom will receive an aggregate number of TmarPart shares equal to the number of TmarPart shares held by Portugal Telecom immediately prior to the merger.

In connection with the business combination,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. As of December 31, 2015, we expect that:

TmarPart will enter into several additional transactions designed to recapitalize TmarPart so that at the timehad used R$8,682 million of the merger of shares, TmarPart will have no net debt;

TmarPart and our company will enter into merger transactions in order to simplify the ownership structure of TmarPart;

The shares of TmarPart will be listed on the Novo Mercado segmentcash proceeds of the BM&FBOVESPA and onPT Portugal Disposition for the NYSE Euronext Lisbon, and ADSs representing the sharesprepayment of TmarPart will be listed on the NYSE; and

The shareholders agreements among the shareholders of TmarPart will be terminated.

We believe that the business combination will:

permit the formation of a single large multinational telecommunications company based in Brazil with more than 100 million customers in seven countries with a total population of approximately 260 million people;

maintain the continuity of operations under the trademarks of Oi and Portugal Telecom in their respective regions of operation, subject to unified control and management by TmarPart;

further consolidate the operationsindebtedness of our company, and Portugal Telecom, withas of the goaldate of achieving significant economiesthis annual report have used an additional R$5,350 million of scale, maximizing operational synergies, reducing operational risks, optimizing efficient investmentsthese net cash proceeds for the prepayment and adopting best operational practices;

In anticipation of the BM&FBOVESPA, the NYSE and NYSE Euronext Lisbon;

diffuse TmarPart’s shareholder base, asPT Portugal Disposition, PT Portugal transferred PTIF, its wholly-owned finance subsidiary, to Oi. As a result of the completion of the PT Portugal Disposition, the indebtedness of PTIF, which no shareholder or grouphad previously been classified as liabilities associated with assets held for sale in our consolidated financial statements, was reclassified as indebtedness of shareholders will hold a majorityour 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 which holds:

our 75% interest in TmarPart’s capital;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.

Proposed Disposition of Africatel

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, 2014 and 2015, we recorded the assets and liabilities of Africatel 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 adoption by TmarPartownership of these interests, particularly our interest in Unitel, we cannot predict when the corporate governance practicessale of the Novo Mercado segment of the BM&FBOVESPA; and

promote greater liquidity of the TmarPart common shares than currently is available to holders of our shares and Portugal Telecom’s shares.

For more information on the proposed business combination and related transactions, see “Item 4. Information on the Company—Our History and Development—Proposed Business Combination.”these assets may be completed.

Business Segments and Presentation of Segment Financial Data

We haveAs a result of our acquisition of PT Portugal, we consolidated the results of PT Portugal and its subsidiaries into our financial statements as from May 5, 2014 until our disposition of PT Portugal on June 2, 2015. Following our acquisition of PT Portugal, we implemented ana new organizational structure that we believe reflects our business activities and corresponds to our principal services. We have identified only one operating segment that corresponds to the principaltelecommunications business in Brazil.

The Telecommunications in Brazil segment includes our services in Brazil, Africa and Asia, including operations that were reported as part of our Fixed-Line and Data Transmission Services, Mobile Services and Other Services segments in prior periods. Prior to our acquisition of PT Portugal, we provide. We reportaccounted for our resultsoperations under three segments: Fixed-Line and Data Transmission Services, Mobile Services, and Other Services. As a result of our implementation of our new organizational structure, our three previously existing segments have been combined into our Telecommunications in three segments to reflect this organizational structure:Brazil segment.

Within our Telecommunications in Brazil segment, our management assesses revenue generation based on customer segmentation into the following categories:

 

Fixed-Line and Data Transmission Services—This segment includes our local fixed-line services (including public telephones), our long-distance services, our fixed-line data transmission services and interconnections to our fixed-line network.

Residential Services, focused on the sale of fixed telephony services, including voice services, broadband, and Pay-TV;

 

Mobile Services—This segment includes our mobile services, including voice, mobile data communications and other value added services, and interconnections to our mobile network.

Personal Mobility, focused on the sale of mobile telephony services to post-paid and pre-paid customers that include voice services and data communication services; and

 

Other Services—This segment includes the operations of our internet portal, ISP services and call center.

SME and Corporate, which includes corporate solutions offered to our small, medium-sized, and large corporate customers, including voice services and corporate data solutions.

In addition to the Telecommunications in Brazil segment, 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 include primarily the following companies: Mobile Telecommunications Limited in Namibia, 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.

We evaluate and manage business segment performance based on information prepared in accordance with Brazilian GAAP, and, accordingly, the segment data included in this annual report“Management’s Discussion and Analysis of Financial Condition and Results of Operations of Oi” section is presented under Brazilian GAAP. We have included a reconciliation of the operating results of our segments to our consolidated results under “—Results of Operations” below.

Critical Accounting Policies and Estimates

Our critical accounting policies and estimates described in note 2(c) to our consolidated financial statements. In preparing our consolidated financial statements in conformity with U.S. GAAP, we relied on estimates and assumptions derived from historical experience and various other factors, including expected future events, that we deemed 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 often requires judgments made by management regarding the effects of matters that are inherently uncertain with respect to our results of operations and the carrying value of our assets and liabilities. Our 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;

provision for doubtful accounts;

 

depreciation of property, plant and equipment;

 

impairment of long-lived assets;

 

provisions;

provisions;

fair value of derivative financial instruments and other financial instruments;

 

derivative instruments;

deferred income taxes and social contribution;

and

 

employee benefits; and

benefits.

amortization of intangible assets.

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 policyof 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 because ouruncertainty 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.

Revenues are generally recognized on an accrual basis. Revenues from local fixed-line, long-distance and post-paid mobile calls and data transmission services are recognized when services are provided. Services provided and not billed at the end of each month are estimated and recorded on an accrual basis. Late-payment interest is recognized upon the issuance of the first bill following the payment of the overdue bill.

Revenues from pre-paid mobile cards are recognized based on the use of the respective credits. Revenue from the sale of public telephone cards is recognized when the credits are effectively consumed by customers. Revenues related to the sale of mobile handsets and accessories are accounted for when the goods are delivered and accepted by the customer.

Revenues from the usage of our network by other telecommunications service providers are recorded based on a formal document of declared traffic and services rendered, the Traffic Exchange Declaration (Documento de Declaração de Tráfego e Prestação de Serviço), or DETRAF, issued by an independent, outsourced clearinghouse.

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.

Provision for Doubtful Accounts

Our provision 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. We include government entities, corporate customers and other telecommunications service providers in the basis for our calculation of the provision for doubtful

accounts. For additional information regarding our provision for doubtful accounts, see note 108 to our consolidated financial statements.

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 allowances may be required.

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 1514 to our consolidated financial statements. 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.

Impairment of Long-Lived Assets

We testLong-lived assets, such as property, plant, and equipment, items and purchased intangible assets for impairment whenever (1) we decidesubject to discontinue activities in which such assetsamortization, are used, or (2) there is evidence that future operating results will not be sufficient to ensure their realization.

Assets with finite useful lives are testedreviewed for impairment whenever events or changes in circumstances indicate that the asset might be impaired. We test asset with indefinite useful lives (goodwill) for impairment at least annually.

Impairment losses, if any, are recognized in an amount by which 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 recoverablefair value. RecoverableFair value is the higher of fair value less cost to sell and the value in use. These calculations require the use of judgments and assumptions. The determination of fairdetermined through various valuation techniques including discounted cash flow models, quoted market values and discounted future operating cash flows requires that we make certain assumptions and estimates with respect to projected cash inflows and cash outflows related to future revenue, costs and expenses. These assumptions and estimates may be influenced by different external and internal factors, suchthird-party independent appraisals, 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 assumptions and estimates could significantly change our consolidated financial statements.deemed necessary.

We have not recorded any impairment of our long-lived assets during the three years ended December 31, 2013.2015.

Provisions

We recognize provisionsLiabilities for losses in labor, taxloss contingencies arising from claims, assessment, litigation, fines and civil proceedings, as well as administrative proceedings. The recognition of a provisionpenalties are recorded when it is probable that the liability has been incurred and the amount can be reasonably estimated, based on the assessmentopinion of management and its in-house and outside legal counsel. The amounts are recognized based on the cost of the riskexpected outcome of loss made for each proceeding, which includes assessing available evidence and recent decisions.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 2220 to our consolidated financial statements, 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 2220 to our consolidated financial statements.

Fair Value of Derivative Financial Instruments and Other Financial Instruments

We recognize derivative financial instruments at fair value based on future cash flow estimates associated with each instrument contracted. The financial assets available for sale related to our investment in Unitel have been valued at fair value according to the operating assets used as basis in the valuation related to the Oi capital increase. Our estimates of future cash flows 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 could have a material effect on the amounts obtained and not necessarily be indicative of the cash amounts that we would receive or pay to settle such transactions.

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 Corporation Law, taking into consideration the provisions of Brazilian tax law, which are materially different from the amounts calculated for Brazilian GAAP and U.S. GAAP purposes. Under Brazilian GAAP and U.S. GAAP, we recognize deferred tax assets and liabilities based on the differences between the carrying amounts and the taxable bases of the assets and liabilities.

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.

Employee Benefits

We record liabilities for employee benefits 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 pension fund benefit liabilities. The accuracy of these assumptions and estimates will determine whether we have created sufficient reserves for the costs of accumulated pensions and healthcare plans, and the amount we are required to disburse each year to fund pension benefits. 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 pension benefits, which could materially impact our results of operations.

The Brazilian Accounting Pronouncements Committee has adopted amendments to CPC 33, “Employee Benefits,” that changed the accounting for defined benefit plans and termination benefits. This amendment eliminated the use of the corridor approach to recognizing actuarial gains and losses of defined benefit plans and required that actuarial gains and losses was recognized directly in the other comprehensive income component of shareholders’ equity. This amendment became effective for periods ending on or after January 1, 2013. The revision

of our accounting for defined benefit plans and termination benefits in compliance with this amendment had a negative impact on our shareholders’ equity of R$314 million (R$207 million net of taxes) as of December 31, 2012. The adoption of this standard does not have any material impact as of December 31, 2011, 2010 or 2009.

Amortization of Intangible Assets

Intangible assets consist primarily of authorizations to provide personal mobile services and radio frequency licenses, licenses to use software and goodwill on the acquisition of investments, which is calculated based on expected future economic benefits.

Amortization of intangible assets, other than goodwill, is calculated under the straight-line method over (1) the effective term of the authorization to provide personal mobile services or of the radio frequency license, or (2) over a maximum period of five years in the case of software licenses.

We do not amortize goodwill in our consolidated statements of income and we are required to test goodwill for impairment at least on an annual basis.

Principal Factors Affecting Our Financial Condition and Results of Operations

Effects of Our Declining Liquidity

As of December 31, 2015, our consolidated cash and cash equivalents and short-term cash investments amounted to R$16,700 million. We expect to use our cash and cash equivalents and short-term cash investments, and financing for which we have commitments under facilities from CDB and BNB, to fund our operations, investments, debt service obligations and working capital requirements during the period in which our operating cash flows are insufficient to fund these cash requirements.

On March 9, 2016, we announced that we had 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 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, as an initial step towards discussions of a potential restructuring of its indebtedness.

Our financial statements for the year ended December 31, 2015 have been prepared assuming that we will continue as a going concern, based on our cash flow projections. Our projections depend on factors such as attainment of traffic volume targets, customer base, launching of bundled products attractive to customers, service sales prices, foreign exchange fluctuation and the success of the efforts to identify and implement financial and strategic alternatives to optimize the liquidity and debt profile.

Should one or more of the assumptions underlying our cash flow projections and other forecasts or the outcome of the efforts to identify and implement financial and strategic alternatives to optimize our liquidity and debt profile not be met, our cash and cash equivalents and short-term cash investments, together with our committed financing, may not be sufficient to meet our contractual obligations and commitments during 2016. If we are unable to successfully restructure our debt on terms satisfactory to our company, we may not be able to execute our business plan or meet our obligations. If we become unable to meet our obligations, we may seek the protection of the courts through a judicially supervised reorganization (recuperação judicial) proceeding in Brazil.

Effects of Investment in and Disposal of Portuguese Business of PT Portugal

On May 5, 2014, we concluded the Oi capital increase in which we issued (1) 121,674,063 of our common shares and 280,483,641 of our preferred shares for an aggregate amount of R$8,250 million in cash, and (2) 104,580,393 of our common shares and 172,025,273 of our preferred shares to Pharol in exchange for the contribution by Pharol to our company of all of the shares of its subsidiary PT Portugal. PT Portugal provides a broad range of telecommunications services in Portugal and owned significant interests in telecommunications companies in Angola, Cape Verde, Namibia, and São Tomé and Principe in Africa and Timor-Leste in Asia.

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.

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. As of December 31, 2015, we had used R$8,682 million of the net cash proceeds of the PT Portugal Disposition for the prepayment of indebtedness of our company, and as of the date of this annual report have used an additional R$5,350 million of these net cash proceeds for the prepayment and repayment of indebtedness of our company. We expect to use the remainder of these net cash proceeds for the repayment of indebtedness of our company.

In anticipation of the PT Portugal Disposition, PT Portugal transferred Portugal Telecom International Finance B.V., or PTIF, its wholly-owned finance subsidiary, to Oi. As a result of the completion of the PT Portugal Disposition, 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 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.

We have accounted for the acquisition of all of the shares of PT Portugal by our company in exchange for our common shares and preferred shares in the Oi capital increase under the purchase method of accounting as a result of which we have recorded the assets and liabilities of PT Portugal on our balance sheet based on the fair value of the identifiable assets acquired and liabilities assumed. We have prepared a purchase price allocation under which we adjusted the carrying values of certain of the assets and liabilities of PT Portugal.

The following table sets forth the adjustments to market value made in the context of the allocation of the fair values of identifiable assets and liabilities of PT Portugal.

As a result of our decision to sell PT Portugal, the revenue and expenses of PT Portugal are presented in our income statement as discontinued operations. In addition, as a result of our decision to sell PT Portugal and its subsidiary Africatel, the assets and liabilities related to PT Portugal and Africatel were classified in our balance sheet as assets held for sale and liabilities of assets held for sale, respectively.

We recorded a loss from discontinued operations for 2014 of R$4,415 million, consisting of a loss from discontinued operations of R$250 million and an allowance for impairment loss at fair value of the PT Portugal investment and divesture-related expenses of R$4,164 million.

We recorded net operating revenue of discontinued operations of R$5,082 million for the period from our acquisition of PT Portugal on May 5, 2014 through December 31, 2014. Our profit on discontinued operations before financial expenses and taxes was R$390 million, or 7.7% of net operating revenue of discontinued operations. Financial expenses of our discontinued operations were R$694 million and we recorded an income tax and social contribution benefit on our discontinued operations was R$54 million. As a result, the loss for our discontinued operations for the year ended December 31, 2014 was R$250 million, or 4.9% of net operating revenue of discontinued operations.

In connection with the reclassification of the assets and liabilities related to PT Portugal and Africatel, we recorded an impairment loss as part of our loss from discontinued operations for 2014 on the investment in PT Portugal, in the amount of R$4,164 million resulting from the recognition of this asset at its fair value less expenses to sell. The sale price used to determine the impairment loss allowance corresponds to the unadjusted purchase price of R$22,267 million (€6,900 million) and liabilities on retirement and other benefits assumed by PT Portugal, amounting to R$3,872 million (€1,200 million).

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 Investment in Rio Forte Commercial Paper and PT Exchange

In preparing the purchase price allocation with respect to our acquisition of PT Portugal, we recognized the write-off of all commercial paper of Rio Forte owned by PT Portugal and PTIF on the date of acquisition and recorded as other assets a right to compensation receivable of R$2,763 million from Pharol, reflecting the face value of this commercial paper.

On July 15 and 17, 2014, Rio Forte defaulted on the commercial paper held by PTIF and PT Portugal. On September 8, 2014, we, TmarPart, Pharol and our subsidiaries PT Portugal and PTIF, entered into the PT Exchange Agreement and the PT Option Agreement. On March 24, 2015, PT Portugal assigned its rights under the PT Exchange Agreement and the PT Option Agreement to PTIF. On March 27, 2015, PT Portugal assigned all of its rights and obligations under the Rio Forte commercial paper that it owned to PTIF. On March 30, 2015, the transactions contemplated by the PT Exchange Agreement were completed through the transfer of Rio Forte commercial paper in the aggregate amount of €897 million to Pharol in exchange for 47,434,872 of our common shares and 94,869,744 of our preferred shares.

As of December 31, 2014, we had the right to compensation from Pharol related to its subscription in the Oi capital increase in the amount of R$2,895 million (equivalent to €897 million) and had an obligation to acquire 47,434,872 of our common shares and 94,869,744 of our preferred shares from Pharol in exchange for this amount under the PT Exchange Agreement, subject to approval by our shareholders at a meeting scheduled for March 26, 2015. Considering that this asset and liability were for the same amount and could be settled with the same entity and at the same time, we stated them on our balance sheet as of December 31, 2014 on a net basis.

Under the PT Exchange Agreement, on March 30, 2015 we complete the share exchange under which Pharol delivered 47,434,872 of our common shares and 94,869,744 of our preferred shares to PTIF and we delivered Rio Forte securities to Pharol in the total principal amount of R$3,163 million (€897 million).

Rate of Growth of Brazil’s Gross Domestic Product and Demand for Telecommunications Services

As a Brazilian company with substantially alla substantial portion of our operations in Brazil, we are affected by economic conditions in Brazil. Brazilian GDP grewdeclined by an estimated 2.3%3.8% in 2013,2015, grew by 0.1% in 2014, and grew by 0.9%2.3% in 2012 and 2.7% in 2011.2013. While we believe that growth in Brazil’s GDP stimulates demand for telecommunications services, we believe that demand for telecommunications services is relatively inelastic in periods of economic stagnation and that the effect on our revenues of low growth or a recession in Brazil would not be material under foreseeable scenarios. However, a substantial and prolonged deterioration of economic conditions in Brazil could have 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 34.739.8 million as of December 31, 20002005 to 44.543.6 million as of April 30, 2013,December 31, 2015, the latest date for which such information has been made available by ANATEL, and the number of mobile subscribers in Brazil increased from 28.886.2 million as of December 31, 20002005 to 271.1257.8 million as of December 31, 2013.2015. 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 two-yearthree-year period ended December 31, 2013,2015, the number of mobile subscribers in Brazil has growndeclined at an average rate of 10.3%4.3% per year, while the number of fixed lines in service in Brazil during the two-yearthree-year period ended December 31, 2013,2015 has declined byat an average rate of 12.4%6.3% per year. As the incumbent provider of fixed-line services and a provider of mobile services in Region I and Region II,our service areas, we are both a principal target and a beneficiary of this trend. During the two-yearthree-year period ended December 31, 2013,2015, the number of our mobile subscribers in Region II has growndecreased at an average rate of 19.8%1% per year from 8.149.2 million at December 31, 20112012 to 9.748 million at December 31, 2013 and the number of mobile subscribers in Region I has grown at an average rate of 11.3% per year from 27.1 million as of December 31, 2011 to 30.2 million at December 31, 2013,2015, while the number of our fixed lines in service in Region II has declined by an average rate of 10.5%6% per year from 5.218.5 million at December 31, 20112012 to 4.614.9 million at December 31, 2013 and the number of fixed lines in service in Region I of our subsidiary Telemar has declined by an average rate of 13.4% per year from 10.0 million at December 31, 2011 to 8.7 million at December 31, 2013.

2015.

Demand for Our Telecommunications Services

Demand for Our Local Fixed-LineResidential Services

Brazil’s fixed-line penetration level is now similar to that of other countries with similar per capita income, and, as has happened in such other countries, the fixed-line telecommunications customer base has remained stable. Demand for local fixed-line services of our company has reached a plateau in recent years. Because the number of customers our companycustomers terminating their fixed-lineresidential services has exceeded new activations during this period,between December 31, 2012 and December 31, 2015, the number of our fixed lines in service in Region II declined by 0.819.1%, or 3.5 million, betweenduring this period, according to ANATEL. As part of the Transformation Plan, we are focusing 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 5.8% to R$79.6 during 2015 from R$75.2 during 2014. We believe that our renewed 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 from 61.6% as of December 31, 2010 and2014 to 63.3% as of December 31, 20132015.

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 and charge higher monthly fees for these plans. Over the numberpast three years, the percentage of fixed lines inour customers selecting these alternative plans has grown significantly. Subscribers to our alternative residential plans, including our bundled service in Region Iplans, represented 86.4% of Telemar declined by 1.6 million. In addition, the new fixed lines that we have activated betweenour residential customers as of December 31, 2010 and2015 as compared to 82% of our residential customers as of December 31, 2013 generally represent customers2012. We believe that have changed addresses or low-income customers from whom we generate revenues atour alternative residential plans contribute to a rate belownet increase in our averageresidential services revenue per customer.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 pansplans that include mobile services, broadband services andOi TV subscriptions to our fixed-line customers. As a result of these service offerings, we expect that the rate of decline in numbermonthly disconnections of our fixed lines in service will be reduced.have declined. As of December 31, 2013, 35.2%2015:

11.7% of our fixed lines in service also subscribed for ADSL service. As of December 31, 2013, 7.6% of our local fixed-lineresidential customers subscribed for bundled service packages, which accountaccounted for 28.9%28.6% of our post-paid mobile subscribers as each fixed-line subscriber may include multiple mobile devices in a bundled plan.

We are required under ANATEL regulations and our concession contracts to offerplan, a basic service plan to our fixed-line residential customers that permits 200 minutesdecrease of usage of our fixed-line network to make local calls. A basic plan customer pays a monthly fee for this service, and when the customer makes local calls in excess of this limit, we charge the customer for the excess minutes on a per-minute basis. We offer alternative local fixed-line plans that include significantly larger numbers of minutes and charge higher monthly fees for these plans, although these monthly fees represent a discount0.6% from the amount that the customer would be charged under our basic plan if the customer used the number29.2% of minutes included in the alternative plan. As the number of our customers selecting these alternative plans has grown in response to our marketing and promotional efforts, we have recorded increased revenues for monthly subscription fees, offset by corresponding declines in revenues for the use of excess minutes. Subscribers to our alternative fixed-line plans represented 80.5% of our fixed lines in servicesubscribers as of December 31, 2013 as compared to 55.0% of the fixed lines in service2014;

51.0% of our company and Telemarresidential customers subscribed for broadband services (whether separately or as part of a bundled service plan), an improvement of 3.0% from the 48.0% of subscribers as of December 31, 2010. We believe that our alternative local fixed-line plans contribute to a net increase in our local fixed-line revenue as many subscribers2014; and

11.7% of our alternative fixed-line plans do not use their full monthly allocationsresidential customers subscribed for Pay TV services (whether separately or as part of local minutes.a bundled service plan), an improvement of 0.3% from the 11.4% of subscribers as of December 31, 2014.

The substantial increase in the number of mobile service users in Brazil has also negatively impacted the use of our public telephones. As the incumbent local fixed-line service provider in Region I and Region II, we are required under ANATEL regulations and our concession contracts to meet specified targets with respect to the availability of public telephones throughout our concession area. However, as a larger portion of the population of Region I and Region II uses mobile handsets to make calls when not in proximity to a fixed-line telephone, revenue from the use of our public telephones of our company and Telemar declined by 80.0%85.7% from 20102012 to 2013.2015.

Demand for Our MobilePersonal Mobility Services

Our customer base for mobilemobility services (including customers in our Personal Mobility Services and SME and Corporate Services) has growndeclined from 39.349.2 million at December 31, 20102012 to 50.248.1 million at December 31, 2013.2015, according to ANATEL. We believe that the primary reason thatfor the decline in our Personal Mobility customer base is the reduction in the total number of mobile accesses in Brazil, especially in the second half of 2015. We believe this market shift reflects the trend to consolidate mobile use into a single SIM card, following the launch of new all-net plans and the structural market migration from voice to data in response to the offering of more robust data packages. Additionally, in the second half of 2015, operators in the Brazilian telecommunication sector (including our company) implemented a more intensive policy of disconnecting inactive users (access clean up). As a result, operators reduced regulated costs associated with the maintenance of active accesses for mobile services has been the success of our marketing and promotion campaigns.devices that do not generate revenue.

The market for mobile services is extremely competitive in each of the regions that we serve. During 2013, the average monthly churn rate of our mobile services segment was 4.2% per month. 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. In addition, competitive pressures have in the past required us to introduce service plans under which the monthly and per-minute rates that we charge our mobile customers are lowered, reducing our personal mobility ARPU. During 2015, the average revenuemonthly churn rate of our Personal Mobility Services business was 12.4% per customer.

month.

Our new service offerings have had strong performances in the first months following their releases in late 2015. As of December 31, 2015,Oi Livre has acquired 6.2 million customers, corresponding to 15.9% of our total pre-paid base. We have also been increasing our market share in the pre-paid segment, with a market share of 21.3% as of December 31, 2015, a 1.7% increase compared to December 31, 2014.

We expect our overall mobile services business to continue to grow in terms of its customer base,market share, traffic volumes and revenues from value-added services. However, due to market saturation, the current macroeconomic situation and the trend in SIM card consolidation, we expect future growth in our mobile services business to occur at lower rates than we have historically achieved.

Demand for Our Data TransmissionSME and Corporate Services

Our broadband services customer base (including the broadbandThe number of our customers of Telemar prior to the corporate reorganization)for SME and Corporate Services has growndeclined from 3.2 million at December 31, 2010 to 5.98.9 million as of December 31, 2013, primarily2012 to 7.2 million as a result of (1)December 31, 2015. We believe that the primary reason for the decline in our marketingSME and promotional campaigns, (2)Corporate Services customer base is the growthdeclining macroeconomic conditions in the number of households in Region I and Region II that own personal computers, and (3) a shift in consumer preferences thatBrazil, which has led an increasing numbercaused many of our fixed-lineSME customers to valuecease operations. Our corporate customers, while better able to survive the data transmission speeds available throughcurrent economic instability, often respond by reducing their economic activity and their spending for telecommunications products and services. In addition, provided that our broadband services.

Effects of Expansion of Mobile Data Transmission Services

In December 2007, we acquired theWe have authorizations and radio frequency licenses necessary for us to commence the offering ofprovide 2G, 3G services throughout Region II and TNL PCS acquired the authorizations and radio frequency licenses necessary for us to commence the offering of 2G services in the State of São Paulo and 3G services throughout Region I and Region III. In June 2012, we acquired the authorizations and radio frequency licenses necessary for us to commence the offering of 4G services throughout Brazil. During 2011, 20122015, 2014 and 2013, weOi Mobile undertook extensive capital expenditure projects to

install the network equipment necessary to expand our offerings of these services.services, investing R$1,151 million, R$1,923 million and R$2,241 million, respectively, which has increased in our depreciation expenses. We financed the purchase and installation of our network equipment through loans and vendor financing.

In 2013,2015, our mobile data transmission services, consisting of 2G, 3G and 4G services to mobile handsets and mini-modems, captured approximately 79,0002,857 net additionsdisconnections (calculated based on the number of subscribers at the end of a period less the number of subscribers at the beginning of that period). We began offeringincreased the number of municipalities in which we offered 4G services in 24to 133, covering 51.4% of the urban population of Brazil, as of December 31, 2015 from 45 municipalities, covering 23.1%30.6% of the population of Brazil, during 2013,as of December 31, 2014, and we increased the number of municipalities in which we offered 3G services to 891,1,288, covering 68.0%78.8% of the urban population of Brazil, as of December 31, 20132015 from 6921,011 as of December 31, 2012. In November 2013, we launched our “Oi Conectado” post-paid bundled voice, data and SMS text messaging plan as part of our efforts to expand our base of mobile data transmission customers.2014. We expect that these services together with our 4G services when commenced, will generate significant additions to our mobile customer base and lead to long-term increases in our revenues and operating income before financial income (expenses) and taxes.

The aggregate cost of our 3G authorizations and radio frequency licenses and our 2G authorizations and radio frequency licenses in Region III was R$3,7663,129 million; we are obligated to pay the remaining balance of R$919 million which we will pay to ANATEL in installments through 2023.2019. The cost of our 4G authorizations and radio frequency licenses was R$368 million, which we will pay to ANATELhas been paid in installments through 2020.

During 2013, 2012 and 2011, Oi Mobile and TNL PCS invested R$1,392 million, R$971 million and R$851 million, respectively, in the network equipment necessary to offer these services, which has increased in our depreciation expenses. We financed the purchase and installation of our network equipment through loans and vendor financing.full.

Under our 3G radio frequency licenses, we are required to meet certain service expansion obligations that will require capital expenditures through 2016. Under our 4G radio frequency licenses, we are required to meet certain service expansion obligations that will require capital expenditures through 2019. If we are unable to fund these capital expenditures through our operating cash flows, we mayor incur additional indebtedness or vendor financing obligations to make these capital expenditures, we may be required to default on our obligations under these licenses, which would increase our outstanding indebtednesscould result in requirements to provide completion guarantees and financial expenses.

administrative proceedings by the respective regulatory bodies, which could result in fines.

Effects of Divestment of Non-Core Assets

Beginning in 2012, we entered into various transactions to monetize non-essential assets and acquire the services related to these assets at more favorable financial terms, with an aim to reduce future capital expenditures and maintenance expenses.

In December 2012, we sold our wholly-owned subsidiary Sumbe, which owned approximately 1,200 communications towers and rooftop antennae used in our mobile services business, to São Paulo SPE Locação de Torres Ltda. for R$516 million. Contemporaneously with the sale of these communications towers and rooftop antennae, we entered into an operating lease agreement with a term of 15 years with Sumbe permitting us and our subsidiaries to continue to use space on these communications towers and rooftop antennae for our mobile services business.

In August 2013, we completed the assignment of the right to use 4,226 fixed-line communications towers that formed part of our infrastructure for commercial operations by companies whose core operations consist of providing transmission tower and radiofrequency management and maintenance services. Upon the completion of these assignments, we received proceeds of approximately R$1,087 million. We have entered into agreements to lease the communications towers from the assignees for 20-year terms (renewable for another 20 years), effective upon completion of the assignments.

In November 2013, we completed the assignment of the right to use 2,113 fixed-line communications towers that formed part of our infrastructure for commercial operations by companies whose core operations consist of providing transmission tower and radiofrequency management and maintenance services. Upon the completion of these assignments, we received proceeds of approximately R$687 million. We have entered into agreements to lease the communications towers from the assignees for 20-year terms (renewable for another 20 years), effective upon completion of the assignments.

In December 2013, we and our subsidiary BrTI sold all of our equity interests in GlobeNet (other than Brasil Telecom de Venezuela S.A.) to BTG Pactual YS Empreendimentos e Participações. On January 17, 2014, the sale was concluded for an aggregate amount of R$1,779 million (based on the U.S. dollar-real exchange rate on January 15, 2014), resulting in a gain of approximately R$1,497 million after deducting the book value of the assets and related costs of approximately R$1,497 million. GlobeNet’s principal assets consist of 22,500 kilometers of fiber optic submarine cables, composed of two rings of protected submarine cables, linking connection points between the United States, Bermuda, Colombia and Brazil. As part of this transaction, GlobeNet will supply guaranteed submarine cable capacity to us and our subsidiaries at a fixed price for a term of 13 years.

In December 2013,March 2014, we entered into an agreement to sellsold all of our equity interests in aCaryopoceae, our wholly-owned subsidiary, that owns 2,007 mobile telecommunications towers to SBA Torres Brasil, Ltda. in exchange for R$1,525 million, subject tomillion. Caryopoceae owned 2,007 mobile telecommunications towers and rooftop antennae used in our mobile services business. Contemporaneously with the completionsale of certain customary conditions precedent. The parties have also agreed that, upon the transfer of such equity interests,this subsidiary, we shall enterentered into long-terman operating lease agreements to permitwith a 15-year term (renewable for another five years) with Caryopoceae permitting us to continue to use space on these communications towers for our mobile services business. We expect

In December 2014, we sold all of our equity interests in Tupã Torres, our wholly-owned subsidiary, to complete this transaction bySBA Torres Brasil, Ltda. for R$1,172 million. Tupã Torres owned 1,641 mobile telecommunications towers and rooftop antennae used in our mobile services business. Contemporaneously with the first quartersale of 2014.Tupã Torres, we entered into an operating lease with a 15-year term (renewable for another five years) with Tupã Torres permitting us to continue to use space on these communications towers for our mobile services business.

As a result of these transactions, we have received cash related to these transactions and recorded gains on disposals of these assets of R$2002,399 million during 20122014 and R$1,497 million during 2013. As a result of these transactions, the amount of property and equipment that we record has been reduced, and consequently we will no longer record depreciation and amortization expenses relating to these assets, nor will we be required to maintain these assets. As a result of our entering lease and other agreements to continue to use these assets in the provision of our services, we expect our leaseexpenses and related expensescommitments relating to increase in future periods.operating leases have increased.

Effects of CompetitionInvestments 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 Ratesvaluation report prepared by Banco Santander on the valuation of Pharol’s operating assets that We Realizewas 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.

As a result of our decision to sell Africatel, the assets and liabilities related to Africatel, including its investment in Unitel and the Discounts We Recordaccounts receivable relating to declared and unpaid dividends of Unitel, were classified in our balance sheet as assets held for sale and liabilities of assets held for sale, respectively.

The Brazilian telecommunications industry is highly competitive. The competitive environment is significantly affected by key trends, includingAs of December 31, 2015, as a result of our updating the convergence of technologymain assumptions and services enables telecommunications service providers that were previously limited to providing a single service to provide services in other industry segments, such asmaterial estimates used in the case of broadband services provided by cable television service providers and by mobile service

providers (using 3G technology) and in the case of traditional fixed-voice services transmitted by mobile telecommunications service providers.

In response to these competitive pressures, (1) we may offer our services at rates below the rate caps established by ANATEL, and (2) from time to time we offer our services with promotional discounts or offer additional complimentary services with the purchase of somefair value measurement of our services. We recordinvestment in Unitel, taking into consideration in this assessment possible impacts of actual events related to the services sold atinvestment, notably the rates established under our service plans or at rates approved by ANATELlawsuits filed against Unitel and recordits shareholders in 2015, we determined a fair value of the amountinvestment in Unitel of these services represented by the promotional discounts or delivered onR$3,436 million and recognized a complimentary basis as discounts and returns in our income statement.loss of R$408 million.

Effects of Adjustments to Our Regulated Rates and Inflation

Telecommunications services rates are subject to comprehensive regulation by ANATEL. Our rates for local fixed-line services, domestic long-distance services, mobile services, interconnection to our fixed-line network, and EILD and SLD services are subject to regulation by ANATEL.

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. As a result, the mobile interconnection rates for Regions I, II and III declined by 25% each in February 2014, 33.3% each in February 2015 and 40.0%, 35.2% and 27.6%, respectively, in February 2016, with additional cuts approved through 2019. In addition, ANATEL approved cuts for most of our fixed interconnection rates ranging from 9.1% and 20.0 in February 2016, with additional cuts approved through 2019. In addition, ANATEL has reduced the substantially reduced our VC Rates during 2013 and 2015, as described

under the caption “Item 4. Information on the Company—Operations in Brazil—Rates.” These rate reductions have been a primary reason for the decline in our mobile interconnection revenue to R$889 million during 2015 from R$1,399 million during 2014 and R$2,147 million during 2013, and the decline in our fixed-line interconnection revenue to R$316 million during 2015 from R$354 million during 2014 and R$388 million during 2013. However, these rate reductions have also led to a substantial reduction of our interconnection costs, which have declined to R$1,809 million during 2015 from R$2,690 million during 2014 and R$3,966 million during 2013. As a result of the substantial reductions in our interconnection costs, 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.

We are required to obtain ANATEL approval prior to offering new alternative fixed-line or mobile plans. The rates established or approved by ANATEL for our services act as caps on the prices that we charge for these services, and we are permitted to offer these services at a discount from the rates approved by ANATEL. After ANATEL establishes or approves rate caps for these services, these rate caps are subject to annual adjustment based on the rate of inflation, as measured by the IST. Rate caps for local fixed-line plans are adjusted by inflation, as measured by the IST, less an amount that serves as a proxy for productivity gains achieved by our company and the local fixed-line services industry as a whole.

Because substantially all of our cost of services and operating expenses are incurred inreais in Brazil, these rate increases act as a natural hedge against inflation and, as a result, our operating margins have not been materially affected by inflation. However, because these rate adjustments are only made on an annual basis, in periods of severe inflation, we may not be able to pass our increased costs through to our customers as incurred.

A significant portion of ourreal-denominated debt bears interest at the TJLP or the CDI rate, which are partially adjusted for inflation, and the ICPA rate, an inflation index, and, as a result, inflation results in increases in our interest expenses and debt service obligations.

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.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 of December 31, 2013,2015, the total estimated contingency in connection with all pending administrative proceedings brought by ANATEL against us in which we deemed the risk of loss as probable totaled R$1,0461,149 million, including fines which we are contesting through judicial proceedings, and we had recorded an aggregate provision related to these proceedings in the same amount. In the event that we are unsuccessful in obtaining final approval of the inclusion of the R$5 billion of fines and claims we have proposed to be included in the TAC program, we could be required to constitute an additional provision of the portion of these fines and claims for which we have not previously established a provision.

In December 2013, ANATEL approved Resolution No. 629/2013 under which a TAC was adopted permitting telecommunications concessionaires to request that their obligations to pay fines to ANATEL for non-compliance with certain service requirements be satisfied through capital expenditure investments in their networks. Under this

regulation, Oi is currently negotiating several TACs with ANATEL related to fines in an aggregate amount of approximately R$5 billion, which can be classified into four categories of non-compliance: (1) universalization and quality, (2) systemic interruptions and external network, (3) consumer rights and general obligations, and (4) fiscalization.

On January 5, 2016, ANATEL published a decision defining the priority projects in case of TACs executed by any operator and ANATEL. ANATEL will accept projects related to: (1) transport infrastructure based on fiber to the municipal capital; (2) transport infrastructure through high capacity digital radio to the municipal capital; (3) deployment of mobile personal service to provide 3G technology in cities that currently do not have such service; (4) deployment of mobile personal service to provide 4G technology in cities with more than 30,000 inhabitants that currently lack such service; and (5) copper network shortening through FTTC technology in order to provide broadband service. ANATEL also published the factor of regional inequalities to stimulate the implementation of these projects in less developed areas.

If we execute a TAC with ANATEL, then we will be subject to the terms and conditions set forth in the TAC, including any penalties for non-compliance provided therein (in lieu of those set forth in the regulations) for the life of the TAC. We will be required to comply with the regulatory requirements only upon the expiration of the relevant TAC.

During 2013,2015, we recorded provisions related to administrative proceedings brought by ANATEL in the amount of R$6644.6 million. Our provisions related to administrative proceedings brought by ANATEL generally have been sufficient to pay all amounts that we were ultimately required to pay with respect to claims brought by ANATEL.

Effects of FluctuationsInflation

After several years of relatively modest inflation in Exchange Rates betweenBrazil, inflation rates increased substantially during 2015 to annual rates of 10.7% as measured by the RealIGP-DI and the U.S. Dollar

SubstantiallyIBGE. Because substantially all of our cost of services and operating expenses are incurred inreais in Brazil.Brazil, this 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 2015, the benefits of these measures have been weakened 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 ourreal-denominated debt bears interest at the TJLP or the CDI rate, which are partially adjusted for inflation, and the ICPA rate, an inflation index, and, as a result, inflation results in increases in our interest expenses and debt service obligations.

Effects of Fluctuations in Exchange Rates between the Real and the U.S. Dollar and the Euro

Substantially all of our cost of services and operating expenses in Brazil are incurred inreais. As a result, the appreciation or depreciation of thereal 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 inreais 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 thereal against the U.S. dollar results in this network equipment being more costly inreais and leads to increased depreciation expenses. Conversely, appreciation of thereal against the U.S. dollar results in this network equipment being less costly inreais and leads to reduced depreciation expenses.

Our consolidated indebtedness denominated in U.S. dollars and euros represented 34.4%38.2% and 6.7%40.3%, respectively, of our consolidated outstanding indebtedness at December 31, 2013.2015. As a result, when thereal appreciates against the U.S. dollar or the euro:

  

the interest costs on our indebtedness denominated in U.S. dollars or euros declines inreais, which positively affects our results of operations inreais;

 

  

the amount of our indebtedness denominated in U.S. dollars or euros declines inreais, and our total liabilities and debt service obligations inreaisdecline; and

 

our net interest expenses tend to decline as a result of foreign exchange gains that we record.

A depreciation of therealagainst the U.S. dollar has the converse effects.

In order to mitigate the effects of foreign exchange variations, we have establishedhistorically maintained a hedging policy under which our exposure to foreign exchange variations is subject to limits set by our board of directors. In compliance withUnder this policy, we typically enterentered into derivative transactions to swap the foreign exchange rate variation for variations of the CDI. At December 31, 2013,2015, we had entered into hedging transactions in respect of 99.6%99.5% of our consolidated indebtedness affected by exchange rate variations. The purpose of these hedging transactions is to seek to “match” the currency of our debt with that of our revenues to mitigate foreign exchange risk. During 2016, in connection with our consideration of potential plans to restructure our indebtedness, we have not rolled over our non-deliverable forwards and have selectively settled several of our long-term currency swaps. As a result, our exposure to foreign currency fluctuations has increased substantially.

Effect of Level of Indebtedness and Interest Rates

At December 31, 2013,2015, our total outstanding indebtedness on a consolidated basis was R$35,85459,857 million. The level of our indebtedness results in significant interest expenses that are reflected in our income statement. Financial expenses of our continuing operations consist of interest expense, exchange variations of U.S. dollar- and other foreign currency-denominated debt, foreign exchange losses or gains, and other items as set forth in note 76 to our consolidated financial statements. In 2013,2015, we recorded total financial expenses of our continuing operations of R$4,65011,903 million on a consolidated basis, of which R$2,4524,050 million consisted primarily of interest expenses on loans and debentures payable to third parties and R$2,01310,908 million consisted of losses from monetary correction and exchange differences on third-party loans and financings. Part of the financial expenses of our continuing operations were offset by income from derivative transactions of R$5,797 million and by exchange rate gains related to cash maintained offshore to provide a natural hedge of R$3,350 million. During 2015, we hedged our foreign currency denominated debt for which we did not have corresponding foreign currency cash deposits against exchange rate fluctuations; as a result, the cost of such indebtedness was linked to fluctuations in the CDI rate rather than the exchange rate. During 2016, in connection with our consideration of potential plans to restructure our indebtedness, we have not rolled over our non-deliverable forwards and have selectively settled several of our long-term currency swaps. As a result, our exposure to foreign currency fluctuations has increased substantially.

The interest rates that we pay depend on a variety of factors, including prevailing Brazilian and international interest rates and risk assessments of our company, our industry and the Brazilian economy made by potential lenders to our

company, potential purchasers of our debt securities and the rating agencies that assess our company and its debt securities.

Standard & Poor’s, Moody’s and Fitch maintain ratings of our company and our debt securities. Currently, Standard & Poor’s, Moody’s and Fitch maintain ratings of our company on a local and a global basis. On a global basis, Standard & Poor’s maintains a foreign currency rating for our company of “CCC-,” Moody’s maintains a foreign currency rating for our company of “Caa1,” and Fitch maintains a foreign currency rating for our company of “CCC.” Any decision by these agencies to downgrade the ratings downgradesof our company or of our debt securities in the future would likely result in increased interest and other financial expenses relating to loansour borrowings and financings, including debt securities and the inclusion of financial covenants in the instruments governing new indebtedness, and could adversely affectsignificantly reduce our ability to obtain such financing on satisfactory terms or in amounts required by us.

Our export credit facility guaranteed by EKN contained a requirement that we prepay all outstanding amounts in the event that our credit rating was downgraded below Ba2 by Moody’s or BB by Fitch. As a result of the actions

by these rating agencies, we were required to prepay the outstanding principal amount under this export credit agreement of R$202 million in April 2016.

Seasonality

WeOur primary business operations do not have material seasonal operations.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

MergerExclusivity Agreement with LetterOne

In October 2015, we entered into an exclusivity agreement with LetterOne with respect to the negotiation of TNL PCS into Oi Mobilea potential transaction for the specific purpose of allowing a consolidation in the Brazilian telecommunications industry involving a potential business combination with TIM. As part of the potential transaction, LetterOne proposed to make a capital contribution of up to US$4.0 billion in our company, contingent on the completion of the consolidation transaction. On February 25, 2016, we were notified by LetterOne that it had been informed by TIM that the latter was no longer interested in proceeding with the negotiations of a business combination with our company and that without TIM’s involvement, LetterOne could not proceed with transaction as previously planned.

Notice of Default under PTIF Bonds

Under the Trust Deed governing the PTIF Bonds, we were required to file audited financial statements of PTIF as of and for the year ended December 31, 2014 with the Dutch Chamber of Commerce no later than January 31, 2016. On April 29, 2016, the PTIF Trustee delivered a written notice to PTIF and Oi noting that the failure of PTIF to provide the 2014 audited financial statements constituted a potential event of default under the PTIF Bonds and requesting the delivery of those financial statements. PTIF is continuing to work with its auditor to complete the preparation of its 2014 audited financial statements as soon as possible.

The PTIF Trustee has notified PTIF that if PTIF fails to deliver the financial statements on or prior to May 29, 2016 and the MOU, with Portugal Telecom, AG Telecom, LF Tel, PASA, EDSP, Bratel Brasil, BES and Ongoing, in which we and they agreedPTIF Trustee determines that this failure is materially prejudicial to the principles governinginterests of the holders of the PTIF Bonds, the PTIF Trustee could declare that the PTIF Bonds are immediately due and repayable. Under the terms of the PTIF Bonds, the PTIF Trustee is not obliged to exercise its discretion to declare any PTIF Bonds immediately due and repayable or to take any other action to enforce the rights of the holders of the PTIF Bonds unless it shall have been indemnified to its satisfaction and specifically directed or requested to do so by a seriesrequisite percentage of transactions.

Net Operating Revenue

The composition of gross operating revenue by category of service before deduction of value-added and other indirect taxes and discounts is discussed below. Prior to 2013, we did not determine net operating revenue for each category of service as we did not believe such information to be useful to investors.

Gross operating revenue increased by 143.2% in 2012, principally due to (1) our consolidation of the results of Telemar and its subsidiaries as from February 27, 2012 due to the corporate reorganization, which increased the gross operating revenue by R$23,293 million, (2) a 15.7% increase in gross operating revenue of our mobile services segment generated by our legacy operations, the effects of which were partially offset by a 2.3% decline in gross operating revenue of our fixed-line and data transmission services segment generated by our legacy operations.

Net operating revenue increased by 172.2% in 2012, principally due to (1) our consolidation of the results of Telemar and its subsidiaries as from February 27, 2012 due to the corporate reorganization, which increased the net operating revenue by R$16,204 million, and (2) a 16.2% increase in net operating revenue of our mobile services segment generated by our legacy operations, the effects of which were partially offset by a 5.8% decline in net operating revenue of our fixed-line and data transmission services segment generated by our legacy operations. Net operating revenue generated by intersegment sales, which are eliminated in the consolidation of our financial statements, increased by 253.2% in 2012.

Our effective tax rate was 29.9%1,179.5% in 2012,2014, primarily as a result of (1) the tax incentives providedeffect of permanent additions related to the write-off of R$266 million of tax credits related to potential loss on the shares of Pharol held by the SUDENE resulting from a reduction in the basis of calculation of profit in the regions promoted by SUDENE,Telemar, which loweredincreased our effective tax rate by 6.1%1,071.3%, and (2) the tax effect of REFIS permanent additions related to the settlement of principal, fines and interest in amount of R$443 million payable to the Brazilian government’s tax refinancing program through the use of tax loss carryforwards as permitted by Article 2 of Law 12996/2014 and Article 33 of Law 13043/2014, which increased our effective tax rate by 689.7%. These effectsThe effect of this incentivethese factors was partially offset by the tax effect of REFIS permanent exclusion related to the settlement of principal, fines and interest in amount of R$219 million payable to the Brazilian government’s tax refinancing program through the use of tax loss carryforwards, which reduced our effective tax rate.

Our effective tax rate was 11.2% in 2013, primarily as a result of the tax effect of permanent exclusions, primarily as a result of prescribed dividends and other permanent exclusions, which decreased our effective tax rate by 41.2%. The effect of these factors was partially offset by (1) the tax effect of unrecognized deferred tax assets regarding legal entities that are not eligible to recognize tax credits on tax loss carryforwards, which increased our effective tax rate by 1.6%, and (2) the tax effect of permanent additions, primarily as a resultsresult of the net effects of permanent exclusion (additions) of prescribed dividends, nondeductiblenon-deductible fines, tax incentives and sponsorships, which increased our effective tax rate by 0.5%.

As a percentage of net operating revenue, net loss from continuing operations was 2.5% in 2014 compared to net loss from continuing operations of 2.1% in 2013.

Net Loss from Discontinued Operations

Net loss from discontinued operations in 2014 of R$4,086 million consisted of (1) the allowance for loss in the amount of R$3,836 million on the investment of PT Portugal resulting from the recognition of assets of PT Portugal at fair value, less selling expenses, and (2) loss from discontinued operations of PT Portugal in the amount of R$250 million.

Net Income

As a percentage of net operating revenue, our net loss was 16.9% during 2014 compared to 7.1%net income of 2.1% in 2012 from 10.9% in 2011.2013

Liquidity and Capital Resources

Our principal cash requirements consist 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.

Unless our board of directors deems it inconsistent with our financial position, payment of dividends is mandatory under our by-laws and, consequently, may give rise to significant cash requirements in future periods.

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.markets; and

during 2012, 2013 and 2014, sales of non-core assets.

During 2013,2015, our operations generated negative cash flow generated by operations was used primarily forflows of R$1,054 million. As a result, we financed investing activities, fordebt service and working capital requirementsfrom our cash and to service our outstanding debt obligations.cash equivalents and short-term cash investments. As of December 31, 2013,2015, our consolidated cash and

cash equivalents and short-term cash investments amounted to R$3,01616,700 million. As of December 31, 2013,2015, we had working capital of R$2,14712,609 million, which includes net assets and liabilities held for sale of R$6,941 million. We believe

Our financial statements for the year ended December 31, 2015 have been prepared assuming that we will continue as a going concern, based on our cash flow projections. Our projections depend on factors such as attainment of traffic volume targets, customer base, launching of bundled products attractive to customers, service sales prices, foreign exchange fluctuation and the success of the efforts to identify and implement financial and strategic alternatives to optimize the liquidity and debt profile.

Should one or more of the assumptions underlying our cash flow projections and other forecasts or the outcome of the efforts to identify and implement financial and strategic alternatives to optimize our liquidity and debt profile not be met, our working capital ismay not be sufficient for our requirements during 2014.2016.

Cash Flow

Cash Flows from Operating Activities

Our primary source of operating funds ishas historically been cash flow generated from our operations. NetHowever, during 2015, our operations generated negative cash provided by operating activities wasflows of R$7,035 million in 2013, R$3,910 million in 2012 and R$1,839 million in 2011. We consider1,054 million. As a result, cash flows provided by our operating activities to bewere not sufficient for our expected cash requirements related to operations. However,Historically, we generally financehave financed our investments in property, plant and equipment through the use of bank loans, vendor financing, capital markets and other forms of financing. During 2015, we financed investing activities, debt service and working capital from our cash and cash equivalents and short-term cash investments.

Net cash used by operating activities was R$1,054 million during 2015, after giving effect to net cash provided by discontinued operations of R$485 million. Net cash provided by operating activities was R$5,531 million during 2014, including cash flow from discontinued operations of R$1,878 million, and R$7,035 million during 2013.

The R$6,584 million deterioration of our operating cash flows during 2015 was primarily as a result of:

a R$4,792 million increase in net loss to R$9,572 million during 2015 from R$4,780 million during 2014;

the effects of a R$5,371 million increase in non-cash gains from financial derivative transactions to R$5,796 million during 2015 from R$425 million during 2014 as a result of the decline in the value of thereal against the U.S. dollar and the Euro during 2015, particularly during the second half of 2015;

the effects of a 78.8%, or R$3,219 million, decline in net income of discontinued operations, net of tax, to R$867 million during 2015 from R$4,086 million during 2014, as described under the caption “—Results of Operations—Year Ended December 31, 2015 Compared with Year Ended December 31, 2014—Net Income (Loss) from Discontinued Operations”;

the effects of a 74.2% decline in operating cash flows generated by discontinued operations to R$485 million during 2015 from R$1,878 during 2014, primarily as a result of our recording PT Portugal as discontinued operations for eight months during 2015 compared to five months during 2014; and

the effects of a R$1,100 decline in cash flows related to investments in held-for-trading short-term investments, net of redemptions, to a net outflow of R$832 million during 2015 from a net inflow of R$268 million during 2014.

These factors reducing our operating cash flows were partially offset by:

the effects of a 391.4%, or R$5,131 million increase in non-cash gains from interest loss on financial instruments to R$6,443 million during 2015 from R$1,311 million during 2014; and

the effects of a R$2,462 million increase in non-cash deferred income tax expenses to R$2,598 million during 2015 from R$136 million during 2014.

Operating cash flow declined by 21.4%, or R$1,505 million, to R$5,531 million during 2014 from R$7,035 million during 2013, primarily as a result of:

our net loss of R$4,780 million during 2014, compared to our net income of R$604 million during 2013;

the effects of a R$1,705 decrease in cash flows related to investments in held-for-trading short-term investments, net of redemptions, to a net inflow of R$268 million during 2014 from a net inflow of R$1,973 million during 2013; and

the effects of a R$1,613 million change in cash flows from accounts receivable to a net increase of R$1,057 million during 2014 from a net decline of R$556 million during 2013.

These factors reducing our operating cash flows were partially offset by:

the effects of a our recording net income of discontinued operations, net of tax, of R$4,086 million during 2014 as a result of our classification of PT Portugal as discontinued operations;

the effects of a our recording operating cash flows generated by discontinued operations of R$1,878 million during 2014 as a result of our classification of PT Portugal as discontinued operations; and

the effects of a 78.5%, or R$1,215 million, decline in non-cash gains classified as “other” to R$332 million during 2014 from R$1,547 million during 2013.

Projected Sources and Uses of Cash

We anticipate that we will be required to spend approximately R$15.1 billion19,725 million to meet our short-term contractual obligations and commitments and budgeted capital expenditures during 2014,2016, and an additional approximately R$30.4 billion30,672 million to meet our long-term contractual obligations and commitments in 2017 and budgeted2018.

As of December 31, 2015, our consolidated cash and cash equivalents and short-term cash investments amounted to R$16,700 million. We expect to use our cash and cash equivalents and short-term cash investments, and financing for which we have commitments under facilities from CDB and Banco do Nordeste do Brasil S/A, or BNB, to fund our operations, investments, debt service obligations and working capital expendituresrequirements during the period in which our operating cash flows are insufficient to fund these cash requirements.

On March 9, 2016, we announced that we had 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 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, as an initial step towards discussions of a potential restructuring of its indebtedness.

Our financial statements for the year ended December 31, 2015 have been prepared assuming that we will continue as a going concern, based on our cash flow projections. Our projections depend on factors such as attainment of traffic volume targets, customer base, launching of bundled products attractive to customers, service sales prices, foreign exchange fluctuation and 2016, before giving effectthe success of the efforts to any additionalidentify and implement financial and strategic alternatives to optimize the liquidity and debt profile.

Should one or more of the assumptions underlying our cash flow projections and other forecasts or the outcome of the efforts to identify and implement financial and strategic alternatives to optimize our liquidity and debt profile not be met, our cash and cash equivalents and short-term cash investments, together with our committed financing, may not be sufficient to meet our contractual obligations and commitments and capital expenditures that we will incur relating to PT Portugal following the anticipated completion of the business combination. We expect that we will meet these cash requirements for (1) our operating and maintenance activities through sales of our services, and (2) our debt service and capital expenditure commitments through a combination of cash generated from operating activities and cash generated by financing activities, including new debt financings and the refinancing of our existing indebtedness as it becomes due.during 2016.

We have commitmentsa commitment from several financial institutionsCDB to provide us with financing in the future including commitments from under two revolving credit facilities that we entered into in November 2011 and December 2012, an exporta credit facility that we entered into in July 2012 and unused commitments under various other credit facilities described under “—Indebtedness.” In addition, we have an undrawn credit facility with BNB as described below. We pay commitment fees to these financial institutions in connection with their commitments.

In November 2011, Oi, Oi Mobile, Telemar and TNL PCS entered together into a revolving credit facility with a syndicate of international institutions. Under this facility, up to US$1 billion aggregate principal amount will be available for disbursement to the borrowers during the five-year term of this facility. As of December 31, 2013, there were no outstanding loans under this facility. As a result of the merger of TNL PCS with and into Oi Mobile in February 2014, Oi Mobile assumed all of TNL PCS’s rights and obligations under this credit facility.

In December 2012, Oi entered into a revolving credit facility with a syndicate of financial institutions. Under this facility, up to R$1.5 billion aggregate principal amount will be available for disbursement to the borrowers during the three-year term of this facility. As of December 31, 2013, there were no outstanding loans under this facility.

In March 2013, Oi entered into an export credit facility agreement with the Office National Du Ducroire/Nationale Delcrederedienst, or ONDD,BNB, under which ONDDBNB agreed to disburse loans in two tranchesa loan in the aggregate principal amount of up to US$257R$370 million. The proceeds of this export credit facility willloan agreement may be used to fund equipment purchases from Alcatel-Lucent.purchase and expenditures on our fixed-line and mobile telecommunication infrastructure in the Brazilian states of the northeastern region.

Interest on each of these loans is payable semi-annuallyquarterly in arrears throughthe first two years and monthly thereafter until the final maturity in March

Indebtedness

As of December 31, 2013, our total outstanding indebtedness on a consolidated basis was R$35,854 million, consisting of R$4,159 million of short-term indebtedness, all of which represented current portion of long-term indebtedness (or 11.6% of our total indebtedness), and R$31,695 million of long-term indebtedness (or 88.4% of our total indebtedness).

On a consolidated basis, ourreal-denominated Euro-denominated indebtedness as of December 31, 20132015 was R$21,28724,222 million, or 59.4% of our total indebtedness, and our foreign currency-denominatedU.S. dollar-denominated indebtedness was R$14,56622,714 million, or

40.6% ofand our total indebtedness.real-denominated indebtedness was R$12,922 million. As of December 31, 2013,2015, our Euro-denominated indebtedness bore interest at an average rate of 5.2% per annum, our U.S. dollar-denominated indebtedness bore interest at an average rate of 5.1% per annum, and ourreal-denominated indebtedness bore interest at an average rate of 11.84%13.3% per annum, and our foreign currency denominated indebtedness bore interest at an average rate of 4.51% per annum for loans denominated in U.S. dollars and 5.13% per annum for loans denominated in euros.annum. As of December 31, 2013, 76.0%2015, 33.4% of our debt bore interest at floating rates, including the effect of swap operations.

Short-Term Indebtedness

Our consolidated short-term debt, consisting of the current portion of long-term loansborrowings and financings, and debentures, was R$4,15911,927 million as of December 31, 2013.2015. Under our financing policy, we generally do not incur short-term indebtedness, as we believe that our cash flows from operations generally will be sufficient to service our current liabilities.

Long-Term Indebtedness

Our principal sources of long-term debt are:

 

debentures issued in the Brazilian market;

fixed-rate notes issued in the international market;

 

credit facilities with BNDES;

credit facilities with international export credit agencies;

 

unsecured lines of credit obtained from Brazilian and international financial institutions;

 

credit facilities with BNDES;

debentures issued in the Brazilian market; and

real estate securitization transactions; and

credit facilities with a development banks.

transactions.

Some of our debt instruments require that we andOi or Telemar comply with financial covenants, annually, semi-annually or quarterly.quarterly, the most restrictive of which require Oi to maintain a consolidated debt to consolidated EBITDA, determined based on our financial statements prepared in accordance with Brazilian GAAP, for the prior 12-month period less than or equal to 4.0 to 1.0 at the end of each fiscal quarter until maturity. Under each of these debt instruments, the creditor has the right to accelerate the debt if, at the end of any applicable period we are not in compliance with the defined financial covenants ratios.

In anticipation of the completion of the PT Portugal Disposition, we executed temporary modifications of each of our debt instruments that contains such financial maintenance covenants (other than our debt instruments with BNDES), pursuant to which the consolidated debt to consolidated EBITDA ratio that Oi was required to maintain was increased to 6.0 to 1.0 for each of the fiscal quarters of 2015.

Our debt facilities with BNDES contained a number of financial covenants (including ratios with respect to shareholders equity to total assets and consolidated debt to EBITDA) that were measured on a semi-annual basis on June 30 and December 31. Under these debt facilities, noncompliance with two or more of these covenants in one

semi-annual period would automatically trigger the right of BNDES to retain proceeds (in an amount equivalent to three times our next amortization payment under each debt facility with BNDES) from receivables otherwise payable to us in reserve accounts pledged for the benefit of BNDES until such time as the breach is cured.

On June 30, 2015, we were not in compliance with the covenants in each of our debt facilities with BNDES that require Oi to maintain a shareholder’s equity to EBITDA ratio of at least 0.25 to 1 and a consolidated debt to EBITDA ratio of less than 4.0 to 1. As a result, BNDES, had the right to retain proceeds from receivables in reserve accounts pledged for the benefit of BNDES, as described above. In November, 2015, we and BNDES amended the terms of each of our debt facilities with BNDES. As a result of these amendments, (1) the consolidated debt to consolidated EBITDA ratio that Oi was required to maintain was increased to 6.0 to 1.0 for the December 31, 2015 measurement date, (2) the measurement period under each of these debt facilities was reduced to quarterly periods, and (3) BNDES has the right to accelerate the debt under each of these debt facilities, at the end of any applicable period, we are not in compliance with two or more of the financial covenants contained in these debt facilities.

Prior to December 31, 2015, we executed temporary modifications of each of our debt instruments that contains covenants requiring Oi to maintain specified levels of consolidated debt to consolidated EBITDA (other than the debt instruments governing Oi’s 5th and 9th issuances of debentures), pursuant to which Oi was required to maintain a consolidated net debt to consolidated EBITDA ratio of no more than 6.0 to 1.0 as of December 31, 2015. Most of these waivers and amendments continue to require Oi was required to maintain a consolidated net debt to consolidated EBITDA ratio of no more than 6.0 to 1.0 for each of the fiscal quarters of 2016. Upon the expiration of these waivers and under the terms of these amendments, the consolidated debt to EBITDA ratio that Oi is required to maintain under each of these debt instruments will be reduced to their pre-existing levels, the most restrictive of which will require that Oi maintain a consolidated debt to EBITDA ratio of less than 4.0 to 1.0. We have repaid the principal amount outstanding under Oi’s 5th and 9th issuances of debentures in the aggregate amount of R$23 million.

Under the amendments to our revolving credit facility, we agreed to additional conditions applicable to further extensions of credit under this facility. All amounts outstanding under this facility were repaid at maturity in January 2016 and we have terminated this facility.

We were in compliance with theseeach of the financial covenants atapplicable the debt instruments to which Oi and its subsidiaries are a party as of December 31, 2013,2015 (other than the debt instruments governing Oi’s 5th and we believe9th issuances of debentures). We are seeking waivers from those creditors for which these waivers and amendments do not cover all measurement periods to and including the periods ending on December 31, 2016. We cannot provide investors with any assurance that these waivers will be obtained. In the event that we willare unable to obtain waivers of the anticipated breaches of these covenants in these debt instruments, or identify and implement financial and strategic alternatives to optimize our liquidity and debt profile, we may be ableunable to complymeet our obligations under these debt instruments in the event that the creditors under these debt instruments seek to enforce their available remedies.

Under the Trust Deed governing the PTIF Bonds, we were required to file audited financial statements of PTIF as of and for the year ended December 31, 2014 with thesethe Dutch Chamber of Commerce no later than January 31, 2016. On April 29, 2016, the PTIF Trustee delivered a written notice to PTIF and Oi noting that the failure of PTIF to provide the 2014 audited financial covenants during 2014. In addition, we believestatements constituted a potential event of default under the PTIF Bonds and requesting the delivery of those financial statements. PTIF is continuing to work with its auditor to complete the preparation of its 2014 audited financial statements as soon as possible.

The PTIF Trustee has notified PTIF that our complianceif PTIF fails to deliver the financial statements on or prior to May 29, 2016 and the PTIF Trustee determines that this failure is materially prejudicial to the interests of the holders of the PTIF Bonds, the PTIF Trustee could declare that the PTIF Bonds are immediately due and repayable. Under the terms of the PTIF Bonds, the PTIF Trustee is not obliged to exercise its discretion to declare any PTIF Bonds immediately due and repayable or to take any other action to enforce the rights of the holders of the PTIF Bonds unless it shall have been indemnified to its satisfaction and specifically directed or requested to do so by a requisite percentage of the holders of the PTIF Bonds in accordance with these financial covenants will not adversely affect our ability to implement our financing plans.the terms and conditions of the PTIF Bonds.

The instruments governing a substantial portion of our indebtedness contain cross-default or cross-acceleration clauses and the occurrence of an event of default under one of these instruments, could trigger an event of default under other indebtedness or enable the creditors under other indebtedness to accelerate that indebtedness.indebtedness or those obligations. Were a substantial amount of our outstanding indebtedness to be accelerated, we may not have sufficient funds to repay such debt when due.

As of December 31, 2013,2015, all of our debt instruments with BNDES were secured by pledges of certain of our accounts receivable.

The following discussion briefly describes certain of our significant financing transactions.

Data Transmission Equipment Programs

In our access networks, we have been in 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 up to 200 Mbps, and VoIP services.

We have been engaged in a program of acquiringacquired and installinginstalled data communications equipment to convert elements of our networks that useused 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.

Our transport network currently is based on 40 Gbps line rate interfaces and we are upgrading our optical DWDM systems and IP backbone routers to support 100 Gbps line rates. 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 2013,2015 Oi began implementing a new broadband data communications network architecture, which we implemented DWDM linksrefer to as the Single Edge project. This architecture enables Oi to offer access network services such as mobile, broadband, IPTV, and B2B 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 between the Statesline rate interfaces on our new OTN/DWDM network over 30,000 km of Rio de Janeiro, São Paulo, Minas Geraisfiber-optic cable. The OTN/DWDM network is designed to protect against interruptions in service caused by external events and Bahia and extended our optical fiber backbone to Macapá (locatedaccidents. Since January 2014, Our OTN/DWDM network has experienced an average annual growth of traffic, especially in the Statedata traffic, of Amapá).more than 40% per year.

In addition to theexpanding our IP backbone capacity, expansion, we are simplifyingcontinuing to simplify our transport network architecture through the adoption of the single edge concept, which means using one single router to perform manyjoin our commercial, mobile and residential functions such as aggregation, service protocol termination, access gateway and others, that would otherwise would require many specialized routers. We believe that this network simplification will reduce both capital and operational expenditures.

Mobile Services Network Programs

2G & 3G Networks

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. In 2012, we constructed 2,237 new radio base stations to support the growth of our subscriber base and expand the capacity at many of our existing radio base stations. In addition, we have undertaken a project to replace approximately 1,407 of our radio base stations in Region I, all of which employ Alcatel-Lucent technology, with Huawei base stations. We completed the replacement of these radio base stations in December 2012. Our total investment in these projects was R$151 million in 2010, R$100 million in 2011 and R$1,000 million in 2012.

We are engaged in a program of introducing wireless local loop technology which will provide service to our customers through our 2G network in areas not supported by our fixed-line 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 which 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.

In 2014, we extended our service area to include 118 new municipalities with 3G technology. We also activated HSPA+ in 3,302 sites in 2014, which allowed our customers to transfer data at higher speeds. We currently provide 3G services to 1,290 municipalities. We have increased the capacity of our 3G network in order to support the growing demand for mobile data services. We expect to perform capacity expansions in 37% of our existing 3G sites during 2016 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 these4G 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.

In 2013, we commenced offering 4G services in the 12 cities where the FIFA World Cup will be held. Our deployment was conducted in cooperation with TIM, another Brazilian mobile operator, under aheld, pursuant to the 2013 RAN Sharing regime. Through this regime, both operators share the same physical network, each using its own frequency spectrum resources, thus reducing the deployment costs by approximately 50% while maintaining allAgreement. For a discussion of the characteristics of an individual network with respect to our customers. RAN sharing, makes usesee “Item 4: Information on the Company—Network and Facilities—Infrastructure Sharing Agreements—4G Network.” In addition, we extended LTE services in 2015 to cities with over 200,000 inhabitants, including 88 new municipalities, as a result of 3GPP standard features, permitting full technical support. The deployment of this network under a RAN Sharing arrangement was the first of its kind in Latin America.obligations imposed by ANATEL.

In November 2011, we began deploying a network of Wi-Fi hotspots in order to offload traffic from our mobile network. The Oi Wi-Fi network is composed of sub networks that are accessible (1) from indoor public and commercial sites, (2) from outdoor public spaces, and (3) from residential access points of our fixed-line customers that share access points in association with Fon.

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-mobilefixed-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 capacity of our servers dedicated to our corporate customers with a view to increasing the efficiency of the services that we provide to these customers and to support ourOi Smart Cloud service, which we launched in 2012 to provide end-to-end virtual telecommunications and information technology solutions for our corporate clients.

Telecommunications Services Infrastructure 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 operating platform supportingprovisioning 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 centerwill migrate from network operations centers to assist usservice operations centers which will provide more efficient and customer-based support. We expect to complete this project in monitoring transmission failures in real time and assist us in correlating and integrating data related to these transmission failures to their root causes with the aimJanuary 2017.

Another of reducing the frequency of these events. In 2012, we initiatedour projects to consolidate and replace Oi´s systems architecture.

We are currently undergoing an effort to transform the existing service provisioning systems and to create new ones according to a TOM framework. Our goal is to speedimprove 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 is expected to be 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 existing customers and to support our plans to expand our services. Among other investments,In 2015, we are investingactivated 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 expansionquality and data transmission capacity of our national backbone to support the expansion of 3G servicesnetwork as well as protect against interruptions in service caused by external events and new services, the expansion of our satellite network, taking measures to improve our network synchronization and signaling links, taking measures to improve our interconnection traffic, investing in projects to improve route optimization.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 new linear and ringnetwork 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.

U.S. GAAP Reconciliation

We reported net income in accordance with Brazilian GAAP in the amount of R$1,493 million in 2013, R$1,785 million in 2012 and R$1,006 million in 2011. Under U.S. GAAP, we would have reported net income of R$604 million in 2013 and R$866 million in 2012, and net loss of R$557 million in 2011.

Our total shareholders’ equity in accordance with Brazilian GAAP was R$11,524 million as of December 31, 2013 and R$11,109 million as of December 31, 2012. Under U.S. GAAP, we would have reported total shareholders’ equity of R$20,013 million as of December 31, 2013 and R$20,428 million as of December 31, 2012.

The principal differences between Brazilian GAAP and U.S. GAAP that affected our net income in 2013, 2012 and 2011, as well as total shareholders’ equity as of December 31, 2013 and 2012, are described in note 31 to our audited consolidated financial statements included elsewhere in this annual report. The differences that result in significant adjustments relate to the accounting treatment of the following items:

capitalized interest;

business combinations and goodwill;

accounting treatment of the restructuring occurred in February 2012; and

prepaid pension plan costs.

Pension Benefit Plans

Sistel

Sistel is a not-for-profit private pension fund created by Telebrás in November 1977 to supplement the benefits provided by the federal government to employees of the former Telebrás System. The following are pension plans managed by Sistel.

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, 2013,2015, the PBS-A plan had a surplus of R$3.2 billion.2,636.2 million. We were not required to make contributions to the PBS-A plan in 2013, 20122015, 2014 or 2011.2013.

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. As of December 31, 2013,2015, the PBS-TNCP plan had a surplus of R$2125.4 million. We made contributions to the PBS-TNCP plan of less than R$1 million in each of 2013, 20122015, 2014 and 2011.

2013.

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. 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 Amazônia’s active employees that were participants in the PBS-TNCP plan migrated to the CELPREV plan. As of December 31, 2013,2015, the CELPREV plan had a surplus of R$22.4 million. We made contributions to the CELPREV plan of less than R$1 million in each of 2013,2015, 2014 and 2013.

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 2011.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, 2015, the PAMA plan had a surplus of R$1,154 million. We were not required to make contributions to the plan in 2015, 2014 or 2013.

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.

TCSPREV Plan

In December 1999, we and the other companies that participate in the plans managed by Sistel agreed to withdraw the active participants in 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 offered to our employees that participated in the PBS-A plan and new employees who were employed by our company after the privatization of the Telebrás System. Approximately 80% of our active employees that were 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 was closed to new participants in March 2003; however, we resumed offering programmable benefits under this plan to new employees beginning in March 2005. 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, 2013,2015, the TCSPREV plan had a surplus of R$9621,061.4 million. We were not required to make contributions to the TCSPREV plan in 2013, 20122015, 2014 or 2011.

2013.

BrTPREV Plan

In 2000, as a result of our acquisition of CRT, we assumed liability for retirement benefits to CRT’s employees by means of the creation of the Fundador/Alternativo plan, a defined benefit plan, which is 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 pension plan and settled benefit plan offered to our employees that participated in the Fundador/Alternativo plan and new employees of our company. 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 reserved 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, 2013,2015, the BrTPREV plan had a deficit of R$640541 million, which is being amortized through 2022.2019. Since February 2003, we have been making additional monthly contributions to the Fundador/Alternativo plan and the BrTPREV plan to reduce these deficits. During 2011, 20122015, 2014 and 2013, we contributed R$91139 million, R$95123 million and R$117 million, respectively, to the BrTPREV plan and the Fundador/Alternativo plan to reduce these deficits.

BrTPREV Plan ended the year 2015 with a deficit of R$87 million, however, holds a significant portfolio of government securities (NTN-B) marked the maturity, ensured profitability higher than the actuarial target of the Plan. This position also recognized by Resolution 16/2014 CNPC brings a slightly lower result than recorded deficit. The net result of long position and the deficit is still a negative R$27 million, but close to only about 1.1% of total Mathematical Reserves Plan.

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, 2013,2015, the PBS-Telemar plan had a surplus of R$2833.5 million. We were not required to makemade contributions to the PBS-Telemar plan of less than R$1 million in 2013, 2012 or 2011.2015, 2014 and 2013.

TelemarPrev Plan

In September 2000, Telemar began sponsoring the TelemarPrev plan, a private defined contribution pension plan and settled benefit plan offered to Telemar’s employees that participated in the PBS-Telemar plan and new employees who were employed by Telemar after the privatization of the Telebrás System. Approximately 96% of Telemar’s active employees that were 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, 2013,2015, the TelemarPrev plan had a surplus of R$481million.482.9 million. We were not required to makemade contributions to the plan of less than R$1 million in 2015, 2014 and 2013.

The TelemarPrev Plan ended the year 2015 with a deficit of R$94 million; however, because this plan holds a significant portfolio of government securities that are marked to maturity, assuring a return higher than the actuarial target of this plan. This position is higher than the deficit recorded, with a positive net result of R$74 million, recognized by Resolution National Council of Supplementary Pension (CNPC) No 16/2014.

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 2013, 2012 or 2011.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, 2015, the PAMEC-BrT plan had a deficit of R$2.6 million. We made contributions to the PAMEC-BrT plan of less than R$1 million in each of 2015, 2014 and 2013.

TmarPartDecrease of Caravelas shareholding interest

TmarPart has two outstanding classesIn March 2016, we received a letter from BTG Pactual Asset Management S.A. DTVM, or BTG Pactual AM informing us that Caravelas had reduced its shareholding interests in our company from 7.52% to approximately 3.54% of share capital:our common stock, as a result of the partial redemption and subsequent transfer of assets to the former quotaholder of Caravelas.

In the merger of TmarPart with and into Oi, the net assets of TmarPart, in the amount of R$122.4 million were 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 transfer to the shareholders’ equity of Oi of goodwill derived from the acquisition of equity interest recorded by Bratel Brasil, AG Telecom, LF Tel, and TmarPart, in accordance with applicable Brazilian law. In the merger of TmarPart with and into Oi, shareholders of TmarPart received the same number of shares see “Item 4. Information onof Oi as were held by TmarPart immediately prior to the Company—Our Historymerger of TmarPart with and Development—Proposed Business Combination.”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.

Voluntary Share Exchange

On October 8, 2015, we completed a voluntary share exchange under which we had offered (1) the holders of our preferred shares (including preferred shares represented by the Preferred ADSs), the opportunity to convert their preferred shares into our common shares at a ratio of 0.9211 common shares for each preferred share, plus cash in lieu of any fractional share, and (2) the holders of the Preferred ADSs the opportunity to exchange their Preferred ADSs for Common ADSs at a ratio of 0.9211 Common ADSs for each Preferred ADS, plus cash in lieu of any fractional Common ADS.

Transactions with Contax

On November 30, 2004, Telemar and TNL PCS entered into a call center services agreement with Contax S.A., or Contax, a call center business owned principally by some of the controlling shareholders of TmarPart, according tounder which Contax renders call center services to TNL PCS on a fully outsourced basis. Telemar and TNL PCS agreed to pay an estimated amount of R$550 million per year, subject to adjustment based on services actually rendered at the request of Telemar and TNL PCS. As a result of the merger of TNL PCS with and into Oi Mobile in February 2014, Oi Mobile assumed all of TNL PCS’s rights and obligations under this agreement. As a result of the corporate ownership simplification, as of September 1, 2015 Contax is no longer a related party of our company. Contax currently provides a variety of services to Telemar and Oi Mobile, including customer services for our fixed-line business, in Regions I and III, outbound telemarketing to attract additional mobile customers, customer support for pre-paid and post-paid mobile telephone users, technical support for ADSL subscribers and debt collection services. In 2013,During the period

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

General

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 of December 31, 2013,2015, the total estimated amount in controversy for those proceedings in respect of which the risk of loss was deemed probable or possible totaled approximately R$25,527.430,501 million, and we had established provisions of R$5,616.34,435 million 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 2221 to our consolidated financial statements.

In certain instances, we are required to make judicial deposits or post financial guarantees with the applicable judicial bodies. As of December 31, 2013,2015, we had made judicial deposits in the aggregate amount of R$12,36714,377 million and obtained financial guarantees from third parties in the aggregate amount of R$13,193.814,013 million. During 2013,2015, we paid fees in the aggregate amount of R$145.9246 million to the financial institutions from which we had obtained these guarantees, and as of December 31, 2013,2015, we had pledged 18,117,553 common1,811,755 of our preferred shares, representing 1.15% of Telemar, representing 5.27% of itsour 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, 2013,2015, 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$18,636.324,540 million and we had recorded provisions of R$640.4492 million relating to these proceedings.

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 2221 to our consolidated financial statements. 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, 2013,2015, we deemed the risk of loss as possible with respect to approximately R$5,865.610,144 million of these assessments and had not recorded any provisions in respect of these assessments. As of that date, we had recorded provisions in the amount of R$361.5308 million 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, 2013,2015, we deemed the risk of loss as possible with respect to approximately R$2,078.22,908 million of these assessments and had not recorded any provisions in respect of these assessments. As of that date, we had recorded provisions in the amount of R$67.471 million 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, 2013,2015, we deemed the risk of loss as possible with respect to approximately R$2,284.13,161 million of these assessments and had not recorded any provisions in respect of these assessments. As of that date, we had recorded provisions in the amount of R$147.4 million for assessments of the FUST in respect of which we deemed the risk of loss as probable.

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-

partythird-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, 2013,2015, we deemed the risk of loss as possible with respect to approximately R$1,002.11,029 million of these assessments and had not recorded any provisions in respect of these assessments. As of that date, we had recorded provisions of R$12.529 million 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$1,026.41,026 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$584.5585 million. Both TNL and the Brazilian federal tax authorities filed appeals, with respect to which decisions are pending. As of December 31, 2013,2015, we deemed the risk of loss as possible with respect to approximately R$150.83,290 million of these assessments and had not recorded any provisions in respect of this claim.

ILL

TNL used credits from the Tax on Net Profit(Imposto sobre Lucro Líquido), or ILL, to offset certain other taxes based on decisions rendered by the Brazilian Federal Supreme Court in cases brought by other taxpayers that have held this tax unconstitutional. No final administrative or judicial ruling has been rendered setting forth the criteria by which to calculate the amounts permitted to be offset. As of December 31, 2013,2015, we had recorded provisions in the amount of R$20.07 million for those assessments in respect of which we deem the risk of loss as probable.

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, 2013,2015, we deemed the risk of loss as possible with respect to approximately R$6,315.43,515 million of these assessments and had not recorded any provisions in respect of these assessments. As of that date, we had recorded provisions in the amount of R$31.777 million 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, 2013,2015, the total estimated contingency in connection with civil claims against us, including ANATEL proceedings, in respect of which the risk of loss was deemed probable or possible, totaled R$4,871.64,331 million and we had recorded provisions of R$3,833.73,093 million relating to these proceedings.

Administrative Proceedings

Almost every week, we receive notifications from ANATEL requesting information about our compliance with the various services obligations imposed on our company by virtue of our concession agreements. When we are not able to comply with these requests or with our concession obligations, ANATEL may initiate administrative proceedings to impose sanctions on us. We have received various notifications, mainly for not meeting certain goals or obligations set out in the General Plan on Universal Service Goals or the General Plan on Quality Goals, such as responding to complaints relating to billing errors, requests for service repairs on a timely basis and requests from locations with collective or individual access.

As of December 31, 2013,2015, we deemed the risk of loss as possible with respect to approximately R$143.8144 million of these claims and had not recorded any provisions in respect of these claims. As of that date, we had recorded provisions in the amount of R$1,045.51,149 million, including fines which we are contesting through judicial proceedings, for those claims in respect of which we deemed the risk of loss as probable. In the event that we are unsuccessful in obtaining final approval of the inclusion of the R$5 billion of fines and claims we have proposed to be included in the TAC program, we could be required to constitute an additional provision of the portion of these fines and claims for which we have not previously established a provision.

As a condition to ANATEL’s approval of the Portugal Telecom Alliance, ANATEL required that Telemar and Oi pay all pending administrative fines, amounting to approximately R$218 million, regardless of the procedural posture of the proceedings which Telemar and Oi had instituted to contest these fines. Telemar and Oi deemed the risk of loss as possible and had not recorded any provisions in respect of these claims. Telemar and Oi sought and have been granted injunctive relief which has permitted them to make judicial deposits of these amounts while preserving its rights to contest these fines. ANATEL has appealed these injunctions, which appeals remain pending.

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. 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 Agreement (CRT and Community Telephone Program)

As successor to CRT, which we acquired in July 2000, we are subject to various civil claims. The claims, filed in 1998 and 1999, allege: (1) error in the sale of CRT’s share capital; (2) the illegality of bidding procedure No. 04/98; (3) errors in the calculation of the number of shares offered; (4) procedural nonconformities in the shareholders’ meeting that approved the sale of shares of CRT; and (5) errors in the valuation of the shares of CRT.

We are also 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 financial interest agreements with its fixed-line subscribers. Under these financial interest agreements, customers subscribing to CRT’s fixed-line service had the right to subscribe to a number of CRT shares. The number of shares to be issued to such subscribers was determined based on a formula that divided the cost of the fixed-line subscription by the book value of CRT’s shares.

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 Telecomunicações do Mato Grosso do Sul S.A. – Telems, Telecomunicações de Goiás S.A. – Telegoiás and Telecomunicações do Mato Grosso S.A. – Telemat, which were operating companies that Brasil Telecom Holding acquired in the privatization of Telebrás and which were subsequently merged into our company, we are subject to various civil claims in connection with telephone programs (Community Telephone Programs) established in the States of Mato Grosso do Sul, Goiás and Mato Grosso.

In 2009, two court decisions significantly changed the assumptions underlying our estimate of the potential losses relating to these suits.

On March 30, 2009, the Superior Court of Justice ruled that for suits that had yet to be adjudicated, the number of shares to be issued must be calculated using CRT’s balance sheet at the end of the month in which the shares were issued. However, for those lawsuits that have already been adjudicated, the number of shares to be issued must be calculated according to the most recent judicial decision, which, in most of the cases, used the balance sheet at the end of the year prior to the date on which the shares were issued.

On May 28, 2009, a member of the Brazilian Supreme Court published a decision ruling that the financial interest agreements are not subject to a statute of limitations, which resulted in a change in the likelihood of an unfavorable outcome in these pending cases to probable.

As of December 31, 2013,2015, we had recorded provisions in the amount of R$2,062.71,112 million for those claims in respect of which we deemed the risk of loss as probable.

Customer Service Centers

We are a defendant in 6566 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, 2013,2015, we had recorded provisions in the amount of R$11.212 million 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 ConsumidorSAC)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, 2013,2015, 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, 2013,2015, we had recorded provisions in the amount of R$137.9362 million 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, 2013,2015, we had recorded provisions in the amount of R$587.6471 million 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, 2013,2015, the total estimated contingency in connection with labor claims against us in respect of which the risk of loss was deemed probable or possible totaled R$2,019.61,629 million and we had recorded provisions of R$1,142.3849 million relating to these proceedings.

Legal Proceedings Relating to Our Interest in Africatel

On September 16, 2014, Africatel GmbH received a letter from Samba Luxco in which 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 the letter, Samba

Luxco purported to exercise the alleged put right and thereby require Africatel GmbH to acquire its shares in Africatel.

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 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 GmbH submitted their Statement of Defence. On January 25, 2016, Samba Luxco submitted its Reply and, on March 14, 2016, Pharol and Africatel GmbH submitted their Rejoinder.

The proceedings have been bifurcated, with the merits hearing currently scheduled to take place during November 2016. Dates for a quantum hearing (if necessary) have been reserved in March 2017.

Legal Proceedings Relating to Our Interest 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 entitling PT Ventures to nominate the majority of the members of the board of directors of Unitel and its chief executive officer. Vidatel presented its answer to PT Ventures’ request for arbitration on January 8, 2016. The arbitral tribunal was constituted on April 14, 2016 and the proceedings are ongoing.

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. 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. PT Ventures is seeking to consolidate this arbitration proceeding with the separate arbitration proceeding brought by PT Ventures against the other shareholders of Unitel. We intend to continue to vigorously defend these proceedings.

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, among others, for which we deem the risk of loss as possible and have not recorded any provisions. As of December 31, 2013,2015, we deemed the risk of loss as possible with respect to R$19.926,066 billion of these proceedings. This amount is based on total value of the damages being sought by the plaintiffs. Typically, we believe the value of individual claims to be beyond the merits of the case in question.

Dividends and Dividend Policy

Payment of Dividends

Our dividend distribution policy has historically included the distribution of periodic dividends, based on annual balance sheets approved by our board of directors. On August 13, 2013,The payment of dividends is currently subject only to the provisions of the Brazilian Corporate Law and our board of directors approved an amendment to our shareholder compensation policy forby-laws, which provide that the 2013 to 2016 fiscal years, which provides for dividends towill be paid annually in the estimated amount of R$500.0 million, representing approximately the minimum amount necessary to meet the following objectives: (1) pay dividends in the amount equivalent to the greatest of (i) 25% of adjusted net income for the year, (ii) 3% of shareholders’ equity or (iii) 6% of the capital stock; and (2) ensure equitable compensation between classes of preferred and common shares.income. Our distribution policy may be implemented through the distribution of dividends, payment of interest on capital, share grants or redemption, capital reduction or other forms that enable the distribution of funds to shareholders. Payment of intermediate or interim dividends will also be permitted, subject to market conditions, our then-prevailing financial condition and other factors deemed relevant by our board of directors.

When we declare dividends, we are generally required to pay them within 60 days of declaring them unless the shareholders’ resolution establishes another payment date. In any event, if we declare dividends, we must pay them by the end of the fiscal year for which they are declared. Under Article 9 of Law No. 9,249/95 and our by-laws, we also may pay interest attributable to shareholders’ equity as an alternative form of dividends upon approval of our board of directors. For a more detailed description of interest attributable to shareholders’ equity, see “—Payment of Dividends and Interest Attributable to Shareholders’ Equity—Interest Attributable to Shareholders’ Equity.”

The following discussion summarizes the principal provisions of the Brazilian Corporation Law and our by-laws relating to the distribution of dividends, including interest attributable to shareholders’ equity.

Calculation of Adjusted Net Profit

At each annual shareholders’ meeting, our board of directors is required to recommend how to allocate our net profit for the preceding fiscal year, which recommendation our board of executive officers initially submits to our board of directors for approval. This allocation is subject to approval by our common shareholders. The Brazilian Corporation Law defines “net profit” for any fiscal year as our net income after income taxes for that fiscal year, net of any accumulated losses from prior fiscal years and any amounts allocated to employees’ participation in our net profit in that fiscal year. Under the Brazilian Corporation Law, our adjusted net profit available for distribution are equal to our net profit in any fiscal year, reduced by amounts allocated to our legal reserve and other applicable reserves, and increased by any reversals of reserves that we constituted in prior years.

Our calculation of net profit and allocations to reserves for any fiscal year are determined on the basis of financial statements prepared in accordance with Brazilian GAAP.

Reserve Accounts

UnderAs required by the Brazilian Corporation Law and as provided for in our by-laws, we are required to maintain a legal reserve. In addition, we are permitted by the Brazilian Corporation Law to establish the following discretionary reserves:

a contingency reserve for an anticipated loss that is deemed probable in future years. Any amount so allocated in a previous year must be reversed in the fiscal year in which the loss had been anticipated if the loss does not occur as projected or charged off in the event that the anticipated loss occurs;

 

a reserve for investment projects, in an amount based on a capital expenditure budget previously approved by our shareholders;

 

a special goodwill reserve for the merger, which represents the net amount of the counterpart of the premium amount recorded in the asset, pursuant to provisions of CVM Instruction No. 319/1999;

an unrealized income reserve described under “—Mandatory Distributions” below; and

 

a tax incentive investment reserve, included in our capital reserve accounts, in the amount of the reduction in our income tax obligations due to government tax incentive programs.

Allocations to each of these reserves (other than the legal reserve) are subject to approval by our common shareholders voting at our annual shareholders’ meeting.

The Brazilian Corporation Law provides that the legal reserve and the tax incentive investment reserve may be credited to shareholders’ equity or used to absorb losses, but these reserves are unavailable for the payment of distributions in subsequent years. The amounts allocated to the other reserves may be credited to shareholders’ equity and used for the payment of distributions in subsequent years.

Legal Reserve Account

Under the Brazilian Corporation Law and our by-laws, we must allocate 5% of our net profit for each fiscal year to our legal reserve until the aggregate amount of our legal reserve equals 20% of our paid-in capital. However, we are not required to make any allocations to our legal reserve in a fiscal year in which our legal reserve, when added to our other reserves, exceeds 30% of our shareholders’ equity. At December 31, 2013,2015, we had a balance of R$383 million in our legalused this reserve account.to offset losses.

Capital Reserve Accounts

Under the Brazilian Corporation Law, we are also permitted to record a capital reserve that may be used only (1) to absorb losses which exceed retained earnings and income reserves as defined in the Brazilian Corporation Law, (2) to redeem or repurchase share capital and/or participation certificates, (3) to increase our capital, or (4) if specified in our by-laws (which currently do not so specify), to pay preferred share dividends. Amounts allocated to our capital reserves are unavailable for the payment of distributions and are not taken into consideration for purposes of determining the mandatory distributable amount. At December 31, 2013,2015, we had a balance of R$3,97818,745 million in our capital reserve accounts.account

Dividend Preference of Preferred Shares

As permitted by the Brazilian Corporation Law, our by-laws specify that 25% of our adjusted net income for each fiscal year must be distributed to shareholders as dividends or interest attributable to shareholders’ equity. We refer to this amount as the mandatory distributable amount. 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 our share capital divided by the number of our total issued shares, or (2) 3.0% per year of the book value of our shareholders’ equity divided by the number of our 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 apro rata basis.

If the Minimum Preferred Dividend is not paid for a period of three years, holders of preferred shares shall be entitled to full voting rights.

Mandatory Distributions

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 declared.

Under the Brazilian Corporation Law, the amount by which the mandatory distributable amount exceeds the “realized” portion of net income for any particular year may be allocated to the unrealized income reserve, and the mandatory distribution may be limited to the “realized” portion of net income. The “realized” portion of net income is the amount by which our net income exceeds the sum of (1) our net positive results, if any, from the equity method of accounting for earnings and losses of our subsidiaries and certain associated companies, and (2) the profits, gains or income obtained on transactions maturing after the end of the following fiscal year. As amounts allocated to the unrealized income reserve are realized in subsequent years, such amounts must be added to the dividend payment relating to the year of realization.

In additionAccording to the mandatory distributable amount, our by-laws, by proposal of our executive officers and board of directors, may recommend that holdersa portion corresponding to up to 75% of our common shares approveadjusted net income, must be used to form an equity replenishment reserve, in order to replenish our capital and equity position to be used for investments and debt reduction. The remaining balance will be allocated as approved by the paymentshareholders. The balance of additional distributions. Distributions madethe equity replenishment reserve,plus the balances of the other profit reserves,minus the realizable profit reserves and reserves for contingencies, may not exceed 100% of the capital stock and, upon reaching the 100% threshold, the shareholders may decide to holders of our preferred shares are computed in determining whether we have paid the required mandatory distribution. We net any payment of interim distributions against the required mandatory distribution for that fiscal year.use excess funds to increase capital stock or to distribute dividends.

The Brazilian Corporation Law permits us to suspend the mandatory distribution in respect of common shares and preferred shares if our board of directors reports to our annual shareholders’ meeting that the distribution would be incompatible with our financial condition at that time. Our fiscal council must approve any suspension of the mandatory distribution. In addition, our management must report the reasons of any suspension of the mandatory distribution to the CVM. We must allocate net profit not distributed by our company as a result of a suspension to a special reserve and, if not absorbed by subsequent losses, we must distribute these amounts as soon as our financial condition permits. In case our profits reserves, as defined in the Brazilian Corporation Law, exceed our share capital, the excess must be credited to shareholders’ equity or used for the payment of distributions.

Payment of Dividends and Interest Attributable to Shareholders’ Equity

We may pay the mandatory distributable amount as dividends or as interest attributable to shareholders’ equity, which is similar to a dividend but is deductible in calculating our income tax obligations.

Because our 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 for 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 our ADSs are held in Brazil by the depositary, which has registered with the Brazilian Central Bank as the registered owner of our 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 our 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 Our Preferred Shares and the ADSs.”

In addition, remittances are subject to a Brazilian financial transactions tax, which as of the date of this annual report is 0%, but may be subject to change.

Normative Instruction 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 as of January 1, 2008 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. See “Item 10. Additional Information—Taxation—Brazilian Tax Considerations.”

Provisional Measure 627/2013, or PM 627/2013, published in the Official Gazette on November 12, 2013, introduced changes to differentConsiderations” for information regarding Brazilian tax provisions including, but not limited to paymentsimplications of dividends and interest on netattributable to shareholders’ equity. According to PM 627/2013, companies electing to be taxed under the new regime on January 1, 2014 as opposed to January 1, 2015 will not be subject to retroactive taxation on dividends distributions effectively made before November 12, 2013, as established by NI 1,397/2013. As of the date of this annual report, we have not decided whether we will elect to be taxed under the new tax regime as of January 1, 2014, which is pending regulation by the Brazilian tax authorities. PM 627/2013 is an act of the executive government, and will only become ordinary legislation after it is reviewed by Brazil’s National Congress, which may make significant changes to the new tax rules set out in PM 627/2013. Moreover, if PM 627/2013 does not become ordinary legislation within 120 days from publication, plus the time period established for presidential sanction, it will cease to have effect.

Dividends

We are required by the Brazilian Corporation Law and by ourOur by-laws torequire that we hold an annual shareholders’ meeting which, pursuant to Brazilian Corporation Law, must be held by April 30 of each year. At our annual shareholders’ meeting, our common shareholders may vote to declare an annual dividend. Our payment of annual dividends is based on our audited financial statements prepared for our preceding fiscal year.

Any holder of record of shares at the time that a dividend is declared is entitled to receive dividends. Under the Brazilian Corporation Law, we are 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.

Our board of directors may declare interim dividends based on the accrued profits recorded or the realized profits in our annual or semi-annual financial statements. In addition, we may pay dividends from net income based on our unaudited quarterly financial statements. We may set off any payment of interim dividends against the amount of the mandatory distributable amount for the year in which the interim dividends were paid.

Under the current Brazilian tax law, dividends paid to persons who are not Brazilian residents, including holders of ADSs, will not be 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. See “Item 10. Additional Information— Taxation—Brazilian Tax Considerations.”

Interest Attributable to Shareholders’ Equity

Brazilian companies, including our company, are permitted to pay interest attributable to shareholders’ equity as an alternative form of payment of dividends to our shareholders. These payments may be deducted when calculating Brazilian income tax and social contribution tax. The interest rate applied to these distributions generally cannot exceed the TJLP for the applicable period. The amount of interest paid that we can deduct for tax purposes cannot exceed the greater of:

 

50% of our net income (after the deduction of the provision for social contribution tax and before the deduction of the provision for corporate income tax) before taking into account any such distribution for the period for which the payment is made; and

 

50% of the sum of our retained earnings and income reserves.

Any payment of interest attributable to shareholders’ equity to holders of our common shares or preferred shares or our 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.jurisdiction for this purpose. The definition of “tax haven” jurisdiction for this purpose includes countries and locations (a) that do not impose income tax, (b) that impose income tax 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 owner 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%. See “Item 10. Additional Information—Taxation—Brazilian Tax Considerations.”Considerations” below for a discussion of the definition of “tax haven” jurisdiction being broadened by an interpretation of Law No. 11,727. Under our by-laws, we may include the amount distributed as interest attributable to shareholders’ equity, net of any withholding tax, as part of the mandatory distributable amount.

There are ongoing discussions in Congress regarding possible changes to the tax treatment of interest on shareholders’ equity. There can be no assurance that the current tax treatment will continue to be available in the future.

Prescription of Payments

Our shareholders have three years to claim dividend distributions made with respect to their shares, as from the date that we distribute the dividends to our shareholders, after which any unclaimed dividend distributions legally revert to us. We are not required to adjust the amount of any distributions for inflation that occurs during the period from the date of declaration to the payment date.

Significant Changes

Other than as disclosed in this annual report, no significant change has occurred since the date of the audited consolidated financial statements included in this annual report.

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 Corporation 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 our 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 Corporation Law, a company is either publicly held (companhia aberta), as we are, 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 BM&FBOVESPA or in the Brazilian over-the-counter market. Shares of companies, such as our company, that are listed on the BM&FBOVESPA 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.

Disclosure Requirements

Law No. 6,385 requires that a publicly traded company, such as our company, submit to the CVM and the BM&FBOVESPA certain periodic information, including annual and quarterly reports prepared by management and independent auditors. Law No. 6,385 also requires us to file with the CVM our shareholders’ agreements, notices of shareholders’ meetings and copies of the minutes of these meetings.

CVM Instruction No. 358, which became effective in April 2002, revised and consolidated the requirements regarding the disclosure and use of information related to material facts and acts of publicly traded companies,

including the disclosure of information in the trading and acquisition of securities issued by publicly traded companies.

CVM Instruction No. 358 includes provisions that:

 

establish the concept of a material fact that gives rise to reporting requirements. Material facts include decisions made by the controlling shareholders, resolutions of the general meeting of shareholders and of management of the company, or any other facts related to the company’s business (whether occurring within the company or otherwise related thereto) that may influence the price of its publicly traded securities, or the decision of investors to trade such securities or to exercise any of such securities’ underlying rights;

 

specify examples of facts that are considered to be material, which include, among others, the execution of agreements providing for the transfer of control, the entry or withdrawal of shareholders that maintain any managing, financial, technological or administrative function with or contribution to the company, and any corporate restructuring undertaken among related companies;

 

require the investor relations officer, controlling shareholders, other officers or directors, members of the fiscal council and other advisory boards to disclose material facts;

 

require simultaneous disclosure of material facts to all markets in which the company’s securities are admitted for trading;

 

require the acquirer of a controlling stake in a company to publish material facts, including its intentions as to whether or not to de-list the company’s shares, within one year;

establish rules regarding disclosure requirements in the acquisition and disposal of a material shareholding stake; and

 

prohibit trading on the basis of material non-public information.

Brazilian regulations also require that any person or group of persons representing the same interest that has directly or indirectly acquired an interest corresponding to 5% of a type or class of shares of a publicly traded company must provide such publicly traded company with information on such acquisition 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 appropriate Brazilian newspapers. Such obligation is also triggered whenever the equity interest directly or indirectly held by such person or group of persons representing the same interest increases or decreases to 5%, or any 5% multiple thereof, of a type or class of shares.

Integrated Disclosure

CVM Instruction No. 480, which the CVM issued in December 2009:

 

created two different categories of securities issuers in accordance with the securities that those issuers are authorized to issue in the Brazilian regulated markets and established different disclosure requirements for each category. A category A issuer is authorized to issue any and all securities and is subject to more stringent disclosure requirements. A category B issuer is authorized to issue any and all securities, other than shares, share certificates and other securities issued by the issuer of such shares or shares certificates or by a company of its group that grants to its holders the right to acquire such shares or shares certificates.

 

  

created the current CVM form for annual reports (Formulário de Referência). TheFormulário de Referência requires extensive disclosures in several areas, including, among others, management’s discussion and analysis of the financial statements, management compensation and risk controls and derivative policies.

  

introduced a requirement that an issuer publish an offering note with respect to a public securities offering with information on the public securities offering to supplement theFormulário de Referência.

 

  

classified as Well-Known Seasoned Issuers (Emissor de Grande Exposição ao Mercado) companies (1) that have had securities traded in the BM&FBOVESPA for at least three years, (2) that are in compliance with the CVM rules on current and periodic reporting obligations in the previous 12 months, and (3) which have shares traded in the market with a market value equal or greater than R$5 billion. The CVM is expected to issue regulations regarding which public securities offerings by Well-Known Seasoned Issuers that will permit these issuers to register public securities offerings through an expedited procedure.

Recommendations Regarding Business Combination Transactions Between Affiliated Companies

In September 2008, the CVM issued CVM Practice Bulletin No. 35/08 (Parecer de Orientação No. 35/08) recommending that where a controlling company and its subsidiaries or affiliated companies engage in a business combination transaction, certain additional procedures be followed to protect the non-controlling shareholders. The release constitutes guidance for Brazilian companies engaging in business combination transactions, and does not mandate that any procedure be followed. The release recommends that the constituent companies implement one of the following procedures in connection with a business combination transaction:

 

establish an independent advisory committee to protect the interests of the non-controlling shareholders and to negotiate the terms and conditions for such business combination transaction; or

condition the of approval of the business combination transaction upon the affirmative vote of a majority of the non-controlling shareholders of the controlled company, including the minority holders of the voting and the non-voting shares of the controlled company.

Proxy Solicitation Rules

CVM Instruction No. 481, which the CVM issued in December 2009, sets forth (1) the procedures relating to the public solicitation of proxies for the exercise of voting rights at shareholders’ meetings of publicly held companies, and (2) disclosure requirements to be followed by publicly held companies before such shareholders meetings.

CVM Instruction No. 481 provides that:

 

shareholders that own 0.5% or more of a company’s share capital may nominate members of the board of directors and the fiscal council in a public solicitation of proxies conducted by the company’s management, and that shareholders will be entitled to vote with respect to these nominations;

 

companies that accept digital proxies sent through the internet must allow shareholders who hold 0.5% or more of the company’s share capital to make a public solicitation of proxies through the company’s digital proxy system; and

 

publicly held companies that do not accept digital proxies sent through the internet must pay part of the costs of the public solicitation of proxies made by shareholders that own 0.5% or more of the company’s share capital.

CVM Instruction No. 481 also specifies the information and documents that must be made available to shareholders following the date of the publication of the first call notice for the shareholders’ meeting. The information and documents that must be provided varies according to the agenda of the shareholders’ meeting. This information must be available through the CVM’s website before the shareholders’ meeting, must be prepared in accordance with the requirements of Instruction No. 481, and, if the information and documents relate to the annual shareholders’ meeting, must include management’s discussion and analysis of the financial statements, personal data and history of the nominees for election to the company’s board of directors and/or fiscal council, and a proposal for the compensation of the company’s management.

In 2015, CVM Instruction No. 481 was amended to provide the procedures relating to the exercise of distance voting by the shareholders at the shareholders’ meetings. The distance voting procedure is currently at the discretion of Brazilian publicly held companies and has not yet adopted by us. Such procedure will become mandatory (i) in January 2017, for publicly-held companies with at least one type or class of shares integrating IBrX-100 and IBOVESPA indexes; and (ii) in January 2018, for the other publicly-held companies with shares traded in the stock market.

Trading on the BM&FBOVESPA

Overview of the BM&FBOVESPA

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.

Trading and Settlement

Trading of equity securities on the BM&FBOVESPA is conducted through an electronic trading system called Megabolsa every business day from 10:00 a.m. to 5:30 p.m., São Paulo time. Trading of equity securities on the BM&FBOVESPA is also conducted after market between 6:00 p.m. and 7:30 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.

Since March 2003, market making activities have been allowed on the BM&FBOVESPA. On July 23, 2012, we announced the engagement of Brasil Plural Corretora de Câmbio, Títulos e Valores Mobiliários S.A. (formerly known as Flow Corretora de Câmbio, Títulos e Valores Mobiliários S.A.) as market maker of our common shares and preferred shares on the BM&FBOVESPA. Trading in securities listed on the BM&FBOVESPA 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 BM&FBOVESPA may be suspended at the request of a company in anticipation of the announcement of a material event. A requesting company must also suspend trading of its securities on international stock exchanges on which its securities are traded. The CVM and the BM&FBOVESPA 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 BM&FBOVESPA.

In order to reduce volatility, the BM&FBOVESPA 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.

Settlement of transactions on the BM&FBOVESPA 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 BM&FBOVESPA. The seller is ordinarily required to deliver shares to the clearing and settlement chamber of the BM&FBOVESPA 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 BM&FBOVESPA is significantly less liquid than the NYSE or other major exchanges in the world.

As of December 31, 2013,2015, the aggregate market capitalization of all companies listed on the BM&FBOVESPA was equivalent to approximately R$2,414 billion1.9 trillion (US$1,031490 billion) and the 10 largest companies listed on the BM&FBOVESPA represented approximately 51% of the total market capitalization of all listed companies. By comparison, as of December 31, 2013,2015, the aggregate market capitalization of the companies (including U.S. and non-U.S. companies) listed on the NYSE was approximately US$20.017.8 trillion. The average daily trading volume of the BM&FBOVESPA and the NYSE for 20132015 was approximately R$7.46.8 billion (US$3.52.1 billion) and US$54.764.0 billion, respectively.

Although any of the outstanding shares of a listed company may trade on the BM&FBOVESPA, 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 BM&FBOVESPA 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 our 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 BM&FBOVESPA 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 BM&FBOVESPA only in accordance with the requirements of Annex I of Resolution No. 2,6894,373 of the National Monetary Council. Annex I of Resolution No. 2,6894,373 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. In addition,CVM, as applicable. Subject to limited exceptions provided in the CVM regulation or previous CVM authorization, Annex I of Resolution No. 2,6894,373 requires non-Brazilian holders (1) to restrict their securities trading to transactions on the BM&FBOVESPA or qualified over-the-counter markets. With limited exceptions, non-Brazilian holders maymarkets; and (2) to not transfer the ownership of investments made under Annex I of Resolution No. 2,689 to other non-Brazilian holders4,373 through private transactions. See “Item 10. Additional Information—Exchange Controls—Resolution 2,689”No. 4,373” for further information about Resolution 2,689,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. 2,689.4,373.

BM&FBOVESPA Corporate Governance Standards

In December 2000, the BM&FBOVESPA introduced three special listing segments:

 

Level 1 of Differentiated Corporate Governance Practices;

 

Level 2 of Differentiated Corporate Governance Practices; and

 

  

TheNovo 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.

Our shares joined Level 1 of Differentiated Corporate Governance Practices on December 14, 2012. As a Level 1 company, we must, among other things:

ensure that shares representing 25% of our total share capital are effectively available for trading;

 

adopt offering procedures that favor widespread ownership of shares whenever we make 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 our securities made by our controlling shareholders, if any, directors or executive officers;

 

make a schedule of corporate events available to our shareholders; and

hold public meetings with analysts and investors at least annually.

Pursuant to the regulations of the BM&FBOVESPA, the members of our board of directors and board of executive officers are personally liable for our compliance with the rules and regulations of the BM&FBOVESPA’s Level 1 Listing Segment.

 

ITEM 10.ADDITIONAL INFORMATION

Description of Our Company’s By-laws

The following is a summary of the material provisions of our by-laws and of the Brazilian Corporation Law. In Brazil, a company’s by-laws (estatuto social) are the principal governing document of a corporation (sociedade anônima).

General

Our registered name is Oi S.A., and our registered office is located in the City of Rio de Janeiro, State of Rio de Janeiro, Brazil. Our registration number with the Board of Trade of the State of Rio de Janeiro is No. 33.3.0029520-8. We have been duly registered with the CVM under No. 11312 since March 27, 1980. Our headquarters are located in City of Rio de Janeiro, State of Rio de Janeiro, Brazil. Our company has a perpetual existence.

As of March 6, 2014,December 31, 2015 and May 13, 2016, we had outstanding share capital of R$7,471,208,836.63,21,438,374,154.00, comprised of 1,797,086,404825,760,902 total shares, consisting of 599,008,629668,033,661 issued common shares and 1,198,077,775157,727,241 issued preferred shares, including 84,250,695148,282,003 common shares and 72,808,0661,811,755 preferred shares held in treasury. All of our outstanding share capital is fully paid. All of our shares are without par value. Under the Brazilian Corporation Law, the aggregate number of our non-voting and limited voting preferred shares may not exceed two-thirds of our total outstanding share capital. In addition, our board of directors may increase our share capital up to 2,500,000 common or preferred shares without amendment to our by-laws. However, we have proposed an amendment to our bylaws to change the amount by which our board of directors may increase our share capital to a number of common and preferred shares equivalent to R$34,038,701,741.49, subject to the legal limit for non-voting and limited votingprovided that no preferred shares described below. This amendment will be voted on at an extraordinary general shareholders’ meeting called for March 27, 2014.are issued by the Company in public or private subscriptions.

Corporate Purposes

Under Article 2 of our by-laws, our corporate purposes are:

 

to offer telecommunications services and all activities required or useful for the operation of these services, in conformity with our 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 our 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 our corporate purposes;

 

to provide technical assistance services to other telecommunications companies engaged in activities of common interest;

to perform other activities related to the above corporate purposes.

Board of Directors

Under our by-laws, any matters subject to the approval of our board of directors can be approved only by an absolutea majority of votes of the members of our board of directors. Under our by-laws, our board of directors may only deliberate if a majority of its members are present at a duly convened meeting.

Election of Directors

The shareholders of TmarPart, our controlling shareholder, have entered into shareholders agreements that determine the representation of these shareholders on our board of directors. See “Item 7. Major Shareholders and Related Party Transactions—Major Shareholders— TmarPart Shareholders’ Agreements.” The members of our 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 BM&FBOVESPA and complying with applicable legal requirements.

Qualification of Directors

There is no minimum share ownership or residency requirement to qualify for membership on our board of directors. Our by-laws do not require the members of our board of directors to be residents of Brazil. The Brazilian Corporation Law requires each of our executive officers to be residents of Brazil. The tenure of the members of the board of directors will be conditioned to 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.years after the end of the term of office.

Fiduciary Duties and Conflicts of Interest

All members of our board of directors and their alternates owe fiduciary duties to us and all of our shareholders.

Under the Brazilian Corporation Law, if one of our directors or his or her respective alternate or one of our executive officers has a conflict of interest with our company in connection with any proposed transaction, such director, alternate director or executive officer may not vote in any decision of our board of directors or of our board of executive officers, as the case may be, regarding such transaction and must disclose the nature and extent of his conflicting interest for inclusion in the minutes of the applicable meeting. However, if one of our directors is absent from a meeting of our 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 our 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 Corporation Law provides that the transaction may be nullified and the interested director or executive officer must return to us any benefits or other advantages that he obtained from, or as result of, such transaction. Under the Brazilian Corporation Law and upon the request of a shareholder who owns at least 5.0% of our total share capital, our directors and executive officers must reveal to our shareholders at an ordinary meeting of our shareholders certain transactions and circumstances that may give rise to a conflict of interest. In addition, our company or shareholders who own 5.0% or more of our share capital may bring an action for civil liability against directors and executive officers for any losses caused to us as a result of a conflict of interest.

Compensation

Under our by-laws, our common shareholders approve the aggregate compensation payable to our board of directors, board of executive officers and members of our fiscal council. Subject to this approval, our board of directors establishes the compensation of its members and of our executive officers. See “Item 6. Directors, Senior Management and Employees—Compensation.”

Mandatory Retirement

Neither the Brazilian Corporation Law nor our by-laws establish any mandatory retirement age for our directors or executive officers.

Share Capital

Under the Brazilian Corporation Law, the number of our issued and outstanding non-voting shares or shares with limited voting rights, such as our preferred shares, may not exceed two-thirds of our total outstanding share capital.

Each of our common shares entitles its holder to one vote at our annual and extraordinary shareholders’ meetings. Holders of our common shares are not entitled to any preference in respect of our dividends or other distributions or otherwise in case of our liquidation.

Our preferred shares are non-voting, except in limited circumstances, and do not have priority over our common shares in the case of our liquidation. See “—Voting Rights” for information regarding the voting rights of our 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 our preferred shares.

Shareholders’ Meetings

Under the Brazilian Corporation Law, we must hold an annual shareholders’ meeting by April 30 of each year in order to:

 

approve or reject the financial statements approved by our board of directors and board of executive officers, including any recommendation by our board of directors for the allocation of net profit and distribution of dividends; and

 

elect members of our board of directors (upon expiration of their two-year terms) and members of our fiscal council, subject to the right of preferred shareholders and minority common shareholders to elect members of our board of directors and our fiscal council.

In addition to the annual shareholders’ meetings, holders of our common shares have the power to determine any matters related to changes in our corporate purposes and to pass any resolutions they deem necessary to protect and enhance our development whenever our interests so require, by means of extraordinary shareholders’ meetings.

The notice must contain the meeting’s place, date, time, agenda and, in the case of a proposed amendment to our by-laws, a description of the subject matter of the proposed amendment.

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 athe chairman and the secretary of the meeting. A shareholder may be represented at a shareholders’ meeting by an attorney-in-fact appointed by the shareholder not more than one year before the meeting. The attorney-in-fact must be a shareholder, a member of our board of directors, a member of our board of executive officers, a lawyer or a financial institution, and the power of attorney appointing the attorney-in-fact must comply with certain formalities set forth under Brazilian law.

However, shareholders representing at least two-thirds of our issued and outstanding voting share capital must be present on first call at a shareholders’ meeting called to amend our by-laws. If a quorum is not present, our 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

Our preferred shares generally do not confer voting rights, except in limited circumstances described below. We 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.

Currently, such limitation is being applied to the votes corresponding to the shares held by Bratel B.V. and Pharol, which taken together, exceed the 15% threshold of our 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 our common shares present or represented at the meeting, without taking abstentions into

Our company is required to give effect to shareholdersshareholders’ agreements that contain provisions regarding the purchase or sale of our shares, preemptive rights to acquire our shares, the exercise of the right to vote our shares or the power to control our company, if these agreements are filed with our headquarters in Rio de Janeiro. Brazilian Corporation Law obligates the president of any shareholder or board of directors meeting to disregard any vote taken by any of the parties to any shareholdersshareholders’ agreement that has been duly filed with our company that violates the provisions of any such agreement. In the event that a shareholder that is party to a shareholdersshareholders’ agreement (or a director appointed by such shareholder) is absent from any shareholders’ or board of directors’ meeting or abstains from voting, the other party or parties to that shareholdersshareholders’ 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 shareholdersshareholders’ agreement. Currently, no shareholders’ agreement affecting our shares has been filed with our headquarters in Rio de Janeiro.

This procedure must be requested by the required number of shareholders at least 48 hours prior to a shareholders’ meeting.

Under the Brazilian Corporation Law, shareholders that are not controlling shareholders, but that together hold either:

 

non-voting preferred shares representing at least 10% of our total share capital; or

 

common shares representing at least 15% of our voting capital,

If no group of our common or preferred shareholders meets the thresholds described above, shareholders holding preferred shares or common shares representing at least 10% of our total share capital are entitled to combine their holdings to appoint one member and an alternate to our 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, our 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 our board of directors.

Upon our liquidation, our preferred shares do not have a liquidation preference over our common shares in respect of the distribution of our net assets.assets, but shall be entitled to unrestricted voting rights. In the event of our liquidation, the assets available for distribution to our shareholders would be distributed to our shareholders in an amount equal to theirpro rata share of our legal capital.

Preemptive Rights

Under the Brazilian Corporation Law, each of our shareholders has a general preemptive right to subscribe for our shares or securities convertible into our shares in any capital increase, in proportion to the number of our shares held by such shareholder.

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 our shares. Holders of our ADSs may not be able to exercise the preemptive rights relating to our 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. We are 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 our ADSs, and we may not file any such registration statement.

Redemption, Amortization, Tender Offers and Rights of Withdrawal

Our by-laws or our shareholders at a shareholders’ meeting may authorize us to use our profits or reserves to redeem or amortize our shares in accordance with conditions and procedures established for such redemption or amortization. The Brazilian Corporation 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 our share capital. The Brazilian Corporation Law defines “amortization” (amortização) as the distribution to the shareholders, without a corresponding capital reduction, of amounts that they would otherwise receive if we were liquidated. If an amortization distribution has been paid prior to our liquidation, then upon our 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 our capital.

The Brazilian Corporation Law authorizes usour shareholders to redeemapprove in a shareholders’ meeting the redemption of our shares not held by our controlling shareholders, if any, if after a tender offer effected for the purpose of delisting us as a consequence of delisting or a substantial reduction in the liquidity of our shares,publicly held company, our controlling shareholders, if any, increase their participation

in our total share capital to more than 95%. The redemption price in such case would be the same price paid for our shares in any such tender offer.

The Brazilian Corporation Law and our 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 our 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 our company under certain circumstances described below under “—Rights of Withdrawal.”

Mandatory Tender Offers

The Brazilian Corporation Law requires that if our common shares are delisted from the BM&FBOVESPA or there is a substantial reduction in liquidity of our common shares, as defined by the CVM, in each case as a result of purchases by our controlling shareholders, our controlling shareholders must effect a tender offer for acquisition of our remaining common shares at a purchase price equal to the fair value of our common shares taking into account the total number of our outstanding common shares.

If our controlling shareholders enter into a transaction which results in a change of control of our company, the controlling shareholders must include in the documentation of the transaction an obligation to effect a public offer for the purchase of all our 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 Corporation Law provides that, in certain limited circumstances, a dissenting shareholder may withdraw its equity interest from our company and be reimbursed by us for the value of our common or preferred shares that it then holds.

This right of withdrawal may be exercised by the dissenting or non-voting holders of the adversely affected class of shares (including any holder of preferred shares of an adversely affected class)shares) in the event that the holders of a majority of all outstanding common shares authorize:

 

the creation of preferred shares or a disproportionate increase of an existing class of our preferred shares relative to the other classes of our preferred shares, other than to the extent permitted by our by-laws;

a change of a priority, preference, right, privilege or condition of redemption or amortization of any class of our preferred shares; or

the creation of a new class of preferred shares that has a priority, preference, right, condition or redemption or amortization superior to an existing class of our preferred shares.

In addition, this right of withdrawal may be exercised by any dissenting or non-voting shareholder (including any holder of preferred shares) in the event that the holders of a majority of the outstanding common shares authorize:

a reduction of the mandatory dividend set forth in our by-laws;

 

our participation in a centralized group of companies;

 

a change in our corporate purpose;

 

spinning-off of all or any part of our company, if such spin-off implies (1) a change in our business purpose (except if the spun-off assets revert to a company whose main purpose is the same as ours), (2) a reduction of the mandatory dividend set forth in our by-laws, or (3) our 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 Corporation Law:

 

the merger of our company with another company, or the consolidation of our company, in a transaction in which our company is not the surviving entity;

 

  

the transfer of all of our outstanding shares to another company in anincorporação de ações transaction;

 

  

the transfer of all of the outstanding shares of another company to us in anincorporação de ações transaction; or

the acquisition of control of another company at a price that exceeds certain limits set forth in the Brazilian Corporation Law.

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 we are consolidated or merged with another company, become part of a centralized group of companies, or acquire the control of another company for a price in excess of certain limits imposed by the Brazilian Corporation Law, holders of any type or class of our 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 general indices representative of portfolios of securities traded in Brazil or abroadthe 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 significant change in the corporate purpose, (2) there is a reduction in the mandatory dividend, or (3) the spin-off results in our 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 press releasematerial 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 economicbook value of the shares, generally equal to the book value per share, determined on the basis of our most recent audited balance sheet approved by our shareholders. The economic value of the shares may be lower than the net book value amount if it is based on the economic value of the enterprise, as determined by an appraisal process in accordance with Brazilian Corporation Law. 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 our 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. Our shareholders may reconsider any resolution giving rise to withdrawal rights within 10 days after the expiration of the exercise period of withdrawal rights if we believeour management believes that the withdrawal of shares of dissenting shareholders would jeopardize our financial stability.

Liability of Our Shareholders for Further Capital Calls

Neither Brazilian law nor our by-laws require any capital calls. Our 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 our outstanding share capital have the right to inspect our corporate records, including shareholders’ lists, corporate minutes, financial records and other documents of our company, if (1) we or any of our officers or directors have committed any act contrary to Brazilian law or our by-laws, or (2) there are grounds to suspect that there are material irregularities in our company. However, in either case, the shareholder that desires to inspect our corporate records must obtain a court order authorizing the inspection.

Disclosures of Share Ownership

Brazilian regulations require that (1) each of our direct or indirect controlling shareholders, directly or indirectly,if any, and (2) shareholders who have elected members of our board of directors or fiscal council, and (3) 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 at least 5%, or any 5% multiple thereof, of the total number of our

shares of any type or class to disclose its or their share ownership or divestment to us, and we are 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.

Our controlling shareholders, shareholders that appoint members of our board of directors or fiscal council andif any, members of our board of directors, board of executive officers, or fiscal council and members of other bodies created pursuant to our by-laws with technical or consulting functions must file a statement of any change in their holdings of our shares with the CVM and the Brazilian stock exchanges on which our securities are traded. We also must disclose any trading of our shares by us or our controlled or related companies.

Form and Transfer

Our preferred shares and common shares are in book-entry form, registered in the name of each shareholder or its nominee. The transfer of our shares is governed by Article 35 of the Brazilian Corporation Law, which provides that a transfer of shares is effected by our 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 us 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 our 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 our shares. TransfersProvided that the provisions of Resolution No. 4,373 are observed, transfers of our 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 BM&FBOVESPA operates a central clearing system.system, the CSD. A holder of our 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 clearing and settlement chamber of the BM&FBOVESPACSD (through a Brazilian institution that is duly authorized to operate by the Brazilian Central Bank and maintains a clearing account with the clearing and settlement chamber of the BM&FBOVESPA)CSD). Shares subject to the custody of the clearing and settlement chamber of the BM&FBOVESPACSD are noted as such in our registry of shareholders. Each participating shareholder will, in turn, be registered in the register of the clearing and settlement chamber of the BM&FBOVESPACSD and will be treated in the same manner as shareholders registered in our 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

However, the right to convert dividend payments, payments of interest on shareholders’ equity payments and proceeds from the sale of our 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 andand/or the CVM.CVM, as the case may be.

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 our 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; or (2) resulting from a corporate reorganization effected abroad, as long as the final beneficiaries and the amount of the assets remain the same.

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 relevant dates.Brazilian Corporation 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 our common or preferred shares. See “—Taxation—Brazilian Tax Considerations.”

ADS - Annex V Regulations

II of Resolution No. 1,9274,373

Annex II of Resolution No. 4,373 of the National Monetary Council as amended, provides for the issuance of depositary receipts in foreign markets in respect of shares of Brazilian issuers. It restatesThe Common and amends Annex V to Resolution No. 1,289 of the National Monetary Council, known as the Annex V Regulations. ThePreferred ADS program was approved under the Annex V Regulations by the Brazilian Central Bank and the CVM prior to the issuance of the ADSs. Accordingly, the proceeds from the sale of ADSs by ADR holders outside Brazil are not subject to Brazilian foreign investment controls,Common and holders of the ADSs who are not resident in a “tax haven” jurisdiction are entitled to favorable tax treatment. See “—Taxation—Brazilian Tax Considerations.”

We pay dividends and other cash distributions with respect to our common shares and preferred shares inreais. We have obtained an electronic certificate of foreign capital registration from the Brazilian Central Bank in the name of the depositary with respect to our ADSs to be maintained by the custodian on behalf of the depositary. Pursuant to this registration, the custodian is able to convert dividends and other distributions with respect to our common shares and preferred shares represented by ADSs into foreign currency and remit the proceeds outside Brazil to the depositary so that the depositary may distribute these proceeds to the holders of record of thePreferred ADSs.

Investors residing outside Brazil may register their investments in our shares as foreign portfolio investments under Resolution No. 2,689 (described below) or as foreign direct investments under Law No. 4,131 (described below). Registration under Resolution No. 2,689 or Law No. 4,131 generally enables non-Brazilian investors to convert dividends, other distributions and sales proceeds received in connection with registered investments into foreign currency and to remit such amounts outside Brazil. Registration under Resolution No. 2,689 affords favorable tax treatment to non-Brazilian portfolio investors who are not resident in a “tax haven” jurisdiction, which is defined under Brazilian tax laws as a country that does not impose taxes or where the maximum income tax rate is lower than 20% or that restricts the disclosure of shareholder composition or ownership of investments. See “—Taxation—Brazilian Tax Considerations.”

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:

 

sell those shares on the BM&FBOVESPA and rely on the depositary’s electronic registration for five business days from the date of exchange to obtain and remit U.S. dollars outside Brazil upon the holder’s sale of our preferred shares;

convert its investment in those shares into a foreign portfolio investment under Annex I of Resolution No. 2,689;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.

4,131, subject to the execution of Symbolic FX Agreements.

The custodian is authorized to update the depositary’s electronic registration of the Common and Preferred ADS Depositary to reflect conversions of Common and Preferred ADSs into foreign portfolio investments under Resolution No. 2,689.4,373.

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 bybefore the Brazilian Central Bank by the custodian after receipt of an electronic request from the custodiandepositary 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 ADR program in exchange for ADSs, such holder will be required to present to the custodian evidence of payment of capital gains taxes. The conversion will be effected by the Brazilian Central Bank after receipt of an electronic request from the custodian with details of the transaction. See “—Taxation—Brazilian Tax Considerations” for details of the tax consequences to an investor residing outside Brazil of investing in our common shares or preferred shares in Brazil.

If a holder of ADSs wishes to convert its investment in our shares into either a foreign portfolio investment under Annex I of Resolution No. 2,6894,373 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 shares or preferred shares.shares, respectively. A non-Brazilian holder of common shares 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 orinto which such holder converts such preferred sharesshares) 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. 2,689,4,373, the investor will be subject to less favorable tax treatment than a holder of ADSs. See “—Taxation—Brazilian Tax Considerations.”

Resolution 2,689

All investments made by a non-Brazilian investor under Resolution No. 2,689 are subject to an electronic registration with the Brazilian Central Bank. This registration permits non-Brazilian investors to convert dividend payments, interest on shareholders’ equity payments and proceeds from the sale of our share capital into foreign currency and to remit such amounts outside Brazil.

Under Resolution No. 2,689, 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.

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 Resolution No. 2,689 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 or be registered in registration, clearing and custody systems authorized by the Brazilian Central Bank or by the CVM. In addition, the trading of securities held under Resolution No. 2,689 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 Resolution No. 2,689 are prohibited, except for transfers resulting from a corporate reorganization effected abroad by a non-Brazilian investor, or occurring upon the death of an investor by operation of law or will.

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 Corporation 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 our 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 our 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 our 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 our common shares, preferred shares or ADSs.

Prospective purchasers of our common shares, preferred shares or ADSs should consult their own tax advisors as to the tax consequences of the acquisition, ownership and disposition of our 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 our common shares, preferred shares or ADSs by a holder not deemed to be domiciled in Brazil for purposes of Brazilian taxation, or a Non-Brazilian Holder.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.non-Brazilian holder. Therefore, each Non-Brazilian Holdernon-Brazilian holder should consult its own tax advisor about the Brazilian tax consequences of an investment in our 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.

In addition, the remittances are subject to a Brazilian financial transactions tax, which as of the date of this annual report is 0%, but may be subject to change.

The Normative Instruction 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 as of January 1, 2008 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. See “Item 10. Additional Information—Taxation—Brazilian Tax Considerations.”

Provisional Measure 627/2013, or PM 627/2013, published in the Official Gazette on November 12, 2013, introduced changes to different tax provisions including, but not limited to payments of dividends and interest on net equity.

According to PM 627/2013, companies electing to be taxed under the new regime on January 1, 2014 as opposed to January 1, 2015 will not be subject to retroactive taxation on dividends distributions effectively made before November 12, 2013, as established by NI 1,397/2013.

As of the date of this annual report, we have not decided whether we will elect to be taxed under the new tax regime as of January 1, 2014, which is pending regulation by the Brazilian tax authorities. PM 627/2013 is an act of the executive government, and will only become ordinary legislation after it is reviewed by Brazil’s National Congress, which may make significant changes to the new tax rules set out in PM 627/2013.

Moreover, if PM 627/2013 does not become ordinary legislation within 120 days from publication, plus the time period established for presidential sanction, it will cease to have effect.

Dividends

Dividends paid by a Brazilian corporation, such as Oi, including stock dividends and other dividends paid to a Non-Brazilian Holdernon-Brazilian holder of our 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 Holdernon-Brazilian holder is subject to income tax withholding at the rate of 15%, or 25% if the Non-Brazilian Holdernon-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) that impose restrictions on the disclosure of thewhere local laws do not allow access to information related to shareholding composition, ownership of investments, or of the identity of the ultimate beneficiarybeneficial owners of earnings that are attributed to non-residents. See

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 “—Interpretation of theDiscussion on Definition of ‘Tax Haven’ Jurisdictions.”

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 our 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.

There are ongoing discussions in Congress regarding possible changes to the tax treatment of interest on shareholders’ equity. There can be no assurance that the current tax treatment will continue to be available in the future.

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,non-Brazilian holder, whether to another non-Brazilian resident or to a Brazilian resident, may be subject to income tax withholdingcapital gain taxes in Brazil.

With respect to the disposition of our common shares or preferred shares, as they are assets located in Brazil, the Non-Brazilian Holdernon-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 our ADSs, although the matter is not entirely clear, arguably the gains realized by a Non-Brazilian Holdernon-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 Holdernon-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 our common shares and preferred shares, described above.

As a general rule, gains realized as a result of a disposition of our common shares, preferred shares or ADSs are the positive difference between the amount realized on the transaction and the acquisition cost of our 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,non-Brazilian holder, the type of registration of the investment by the Non-Brazilian Holdernon-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 Holdernon-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 (a “2,689dated 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 Holdernon-Brazilian holder that is not a 2,6894,373 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.

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 our 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 Holdernon-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 2,6894,373 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 Holdersnon-Brazilian holders other than 2,6894,373 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) imposes restrictions on the disclosure ofwhere local laws do not allow access to information related to shareholding composition, of the ownership of investments, or of the identity of the ultimate beneficiarybeneficial owners of earnings that are attributed to non-residents. However, there is doubt as to the application of these criteria by the Brazilian tax authorities. See “—Interpretation of theDiscussion on Definition of ‘Tax Haven’ Jurisdictions.”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 Holdernon-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 our 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 Holdernon-Brazilian holder that is a 2,6894,373 Holder and is not a resident in a “tax haven” jurisdiction for this purpose. The availability of these arguments to any specific holder of our common shares or preferred shares will depend on the circumstances of such holder. Prospective holders of our common shares or preferred shares should consult their own tax advisors as to the tax consequences of the deposit of our common shares or preferred shares in exchange for ADSs.

Any exercise of preemptive rights relating to our 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 our common shares or preferred shares, including the sale or assignment carried out by the depositary, on behalf of Non-Brazilian Holdersnon-Brazilian holders of ADSs, will be subject to Brazilian income taxation according to the same rules applicable to the sale or disposition of our common shares or preferred shares.

As a Non-Brazilian Holdernon-Brazilian holder of ADSs, you may cancel your TmarPart ADSs and exchange them for TmarPart shares. Income tax will not be levied on such exchange, as long as the appropriate rules are complied with in connection with the registration of the investment with the Central Bank, and as long as ADSs are not deemed to be “assets located in Brazil.

Any gain earned by a Non-Brazilian Holdernon-Brazilian holder on the exercise of appraisal rights (which consists of a disposition of Oi shares, in exchange for a cash payment by Oi) will be subject to Brazilian income taxation according to the same rules applicable to the sale or disposition of shares of TmarPart.

Any exercise of preemptive rights relating to the subscription of new TmarPart shares or ADSs, upon a capital increase of TmarPart, will not be subject to Brazilian taxation. Any gain on the sale or assignment of preemptive rights relating to shares of TmarPart, including the sale or assignment carried out by the TmarPart Depositary, on behalf of Non-Brazilian Holdersnon-Brazilian holders of ADSs, will be subject to Brazilian income taxation according to the same rules applicable to the sale or disposition of shares of TmarPart. The current preferential tax treatment for 2,6894,373 Holders, as described above, may be extinguished in the future.

InterpretationOn 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: (i) 15% on the capital gain not exceeding R$5,000,000; (ii) 17.5% on the capital gain amount between R$5,000,000 and R$10,000,000; (iii) 20% on the capital gain amount between R$10,000,000 and R$30,000,000; and (iv) 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 the 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 LTJsTFJs enacted by Brazilian tax authorities by means of Normative Ruling n.Instruction No. 188/2002. More recently, some amendments were implemented in connection with

On June 24, 2008, Law No. 11,727 introduced the concept of LTJ, via the enactment of Law n. 11,727/08, in force as of January 2009, in order to include in said concept the provision in the sense that the country or location which imposes restrictions on the disclosure of shareholding composition or the ownership of the investment should also be considered as a LTJ.

Additionally, Law 11,727/08 also created the concept of privileged tax regimesPrivileged Tax Regimes (“PTRs”), which encompasses the countries and jurisdictions that: (i) do not tax income or tax it at a maximum rate lower than 20%; (ii) 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 toon the non-exercise of a substantial economic activity in the country or a said territory; (iii) do not tax or taxes proceeds generated abroad at a maximum rate lower than 20.0%; or (iv) restrictsrestrict 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 Ruling n.Instruction 1,037/10 (“INNI 1,037/10”), which includes the countries considered as LTJsTFJs and the locations considered as granting privileged tax regimes.

PTRs. Under Section 2 of INNI 1,037/10, companies incorporated as LLCs in the US, and companies benefiting out offrom some holding regimes in Europe, may be considered as granting privileged tax regimes.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 LTJsTFJs and privileged tax regimes,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 Holdersnon-Brazilian holders in Brazilian corporations, such as TmarPart. 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, Normative Ruling No. 1,037NI 1,037/10 and of any related Brazilian tax law or regulation concerning Low or Nil Tax JurisdictionsLTJs, 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: (a) 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 (b) 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.

In particular, foreign exchange transactionsAny inflow of funds related to inflows of funds to Brazil for investments made by Non-Brazilian Holderscarried out on the Brazilian financial and capital markets areby 4,373 Holders is currently subject to the IOF/Exchange Tax at a rate of zero percent rate.

percent. Foreign exchange transactions related to outflows of funds in connection with investments carried out on the Brazilian financial and capital markets are also 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, such as TmarPart, to Non-Brazilian Holders.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)(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 stamp, issue, registration, or similar taxes or duties payable by Non-Brazilian Holdersnon-Brazilian holders of our 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 the common shares, preferred shares or ADSs of Oi, 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 the common shares, preferred shares or ADSs of Oi 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 the common shares, preferred shares or ADSs of Oi pursuant to an exercise of employee stock options or rights or otherwise as compensation for the performance of services, persons that will hold the common shares, preferred shares or ADSs of Oi 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 voting power) of the shares of Oi.

This description does not address any state, local or non-U.S. tax consequences of the acquisition, ownership and disposition of the common shares, preferred shares or ADSs of Oi 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, on 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

particular tax consequences to such holders of the acquisition, ownership and disposition of the common shares, preferred shares or ADSs of Oi, 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 common shares, preferred shares or ADSs of Oi 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 the common shares, preferred shares or ADSs of Oi, 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 the common shares or preferred shares of Oi 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.

Taxation of Dividends

Subject to the discussion below 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 below 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 conditions 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. Such dividends will not be eligible for the dividends received deduction generally allowed to corporate U.S. Holders. Subject to the discussion below 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 the common shares or preferred shares of Oi 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 below 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 common shares, preferred shares or ADSs of Oi, the amount realized generally will be the U.S. dollar value of the payment received determined on the date of disposition. If the common shares, preferred shares or ADSs of Oi 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.

Passive Foreign Investment Company Rules

A Non-U.S. corporation will be classified as a “passive foreign investment company,” or 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 it will not be classified as a PFIC for its taxable year ended December 31, 2013. Oi’s status in future years2015. In addition, Oi believes there is a significant risk it will depend on its assets and activities in those years. Oi has no reason to believe that its assets or activities will change in a manner that would cause it to be classified as a PFIC for the taxable year ending December 31, 20142016 and for future taxable years, unless the market price of Oi’s common shares or any futurepreferred shares significantly increases or Oi reduces the amount of cash and other passive assets it holds relative to the amount of non-passive assets it holds. The application of the PFIC rules is subject to uncertainty in several respects, and Oi must make a separate determination after the close of each taxable year but there can be no assurance that Oi will not be consideredas to whether it was a PFIC for any taxable year because its status will depend on its assets and activities in those years, as well as its actual Market Capitalization as determined at the end of each calendar quarter.such 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 common shares, preferred shares or ADSs of Oi, 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 (exceptand such election becomes available to U.S. Holders.

For each taxable year that Oi is treated as discussed below),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 or preferred shares) 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 that would arise ifof Oi werebeing treated as a PFIC.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 wereis 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 the common shares, preferred shares or ADSs of Oi 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 the common shares, preferred shares, or ADSs of Oi, 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 the common shares, preferred shares or ADSs of Oi, 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 the common shares, preferred shares or ADSs of Oi, 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 the common shares, preferred shares or ADSs of Oi will be treated as ordinary income. The common shares, preferred shares and ADSs of Oi 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 BM&FBOVESPA may constitute a qualified exchange for this purpose provided the BM&FBOVESPA 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 the common shares, preferred shares or ADSs of Oi will continue to trade on the BM&FBOVESPA or the NYSE, respectively, or that the common shares, preferred shares or ADSs of Oi 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 iffor each taxable year that Oi were determinedis treated as a PFIC with respect to be a PFIC,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. HoldersHolder in respect of any of itsOi’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 below above “—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 the common shares or preferred shares of Oi 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 common shares, preferred shares or ADSs of Oi, the amount realized generally will be the U.S. dollar value of the payment received determined on the date of disposition. If the common shares, preferred shares or ADSs of Oi 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.

3.8% Medicare Tax On “Net Investment Income”

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 common shares, preferred shares, or ADSs of Oi.

Information Reporting and Backup Withholding

In general, information reporting will apply to dividends in respect of the common shares, preferred shares, or ADSs of Oi and the proceeds from the sale, exchange or redemption of the common shares, preferred shares, or

ADSs of Oi 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 the common shares, preferred shares, or ADSs of Oi, subject to certain exceptions (including an exception for common shares, preferred shares, or ADSs of Oi 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 common shares, preferred shares, or ADSs of Oi.

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 ourthe products and services of our continuing operations is Brazil, and substantially all of the revenues of our revenuescontinuing operations are denominated inreais.

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. In 2013,2015, approximately 31%32.4% 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 December 31, 20122015 would have resulted in an increase of R$291780.8 million in the cost of our capital expenditures in 2013,2015, 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, 2013,2015 R$14,94847,372 million, or 41.1%78.5%, of our total consolidated indebtedness was denominated in foreign currency. At December 31, 2013,2015, we protected 99.6%99.5% of our indebtedness affected by exchange rate variation against significant variations in exchange rates (primarily U.S. dollars and euros) by using foreign currency swaps, non-deliverable forwards and foreign currency investments. The aggregate amount of our hedge position, including our U.S. dollar and euro cash positions, was US$6,43612,077 million as of December 31, 2013. The2015. Other than with respect to our portfolio of short-term non-deliverable forwards, the maturity of our swap contracts is coupled to the maturity of debt that is hedged by these swap contracts. Our swap contracts and non-deliverable forwards cover our exchange rate risks until February 2016. As of December 31, 2013,2015, the fair value of our swap contracts and non-deliverable forwards was a receivable for the company, in the amount of R$1,5074,876 million. As of December 31, 2013,2015, the aggregate notional principal amount of our swap contracts and non-deliverable forwards was approximately US$9,33315,989 million, which mature in one to eightnine years.

During 2016, in connection with our consideration of potential plans to restructure our indebtedness, we have not rolled over our non-deliverable forwards and have selectively settled several of our long-term currency swaps. As a result, our exposure to foreign currency fluctuations has increased substantially. In 2013,2015, we experienced losses on foreign currency and monetary restatement due to the depreciation of thereal against foreign currencies of R$9261,799 million, including results recorded on our exchange rate hedges (non-deliverable forwards, swaps and foreign currency investments). As we were almost 100% hedged, the potential additional losses on foreign currency and monetary restatement during 20142015 that would result from a hypothetical, instantaneous 10.0% depreciation of thereal against the U.S. dollar and the euro as of December 31, 20132015 would be approximately R$1353 million after giving effect to our results under our exchange rate swaps, 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 thereal against the U.S. dollar and the euro as of December 31, 20132015 would be approximately R$531,530 million, considering the net impact of the increase in our debt obligations and the decrease in our swap position. For further information about our swap agreements, see note 3 to our consolidated financial statements.

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, 2013,2015, our total outstanding indebtedness was R$36,38354,981 million, of which R$23,01120,159 million, or 63.2%33.40%, bore interest at floating rates, including R$19,16711,209 million ofreal-denominated indebtedness that bore interest at rates based on the CDI rate, TJLP rate or IPCA rate, and R$3,8438,950 million of foreign currency-denominated indebtedness that bore interest at rates based on U.S. dollar and Euro LIBOR. As of December 31, 2013,2015, we had interest rate swap agreements under which 76.6%59.60% of our consolidated indebtedness exposed to U.S. dollar and Euro LIBOR, which represents 10.6%14.83% of our total indebtedness, was converted into CDI rates, matching the interest rate index of our investments. As of December 31, 2013,2015, we did not have any outstanding derivative agreements to limit our exposure to variations in the CDI rate, TJLP rate or IPCA rate.

We invest our excess liquidity (R$3,93116,826 million as of December 31, 2013)2015) 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 inreais 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 we hedged our foreign currency denominated debt against exchange rate fluctuations, the cost of such indebtedness is linked to fluctuations in the CDI rate rather than the exchange rate. The potential additional interest expense during 20142016 that would result from a hypothetical, instantaneous and unfavorable change of 100 basis points in the interest rates on January 1, 20142016 would be approximately R$199

132 million after giving effect to our results under our interest rate swaps, 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.

Hedging Policy

We employ financial risk management strategies using cross-currency swaps, interest rate swaps, series swaps and non-deliverable forwards. Our financial risk management strategy is designed to protect us against devaluation of thereal against foreign currencies and increases in foreign currency interest rates, according to our foreign-currency exposure in connection with our financings. We do not enter into derivatives transactions for speculative or any other purposes.

 

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 our 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 our 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 us 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 us is not necessarily tied to the amount of fees the depositary collects from investors.

During the year ended December 31, 2013,2015, we received US$5.5 million in fees anddid not receive reimbursements from the depositary of our ADSs.

PART II

 

ITEM 13.DEFAULTS, DIVIDEND ARREARAGES AND DELINQUENCIES

Not applicable.Under the Trust Deed governing each of the Bonds issued by PTIF (other than the PTIF 6.25% Notes due 2016), or the PTIF Bonds, we were required to file audited financial statements of PTIF as of and for the year ended December 31, 2014 with the Dutch Chamber of Commerce no later than January 31, 2016. On April 29, 2016, Citicorp Trustee Company Limited, the trustee under this Trust Deed, or the PTIF Trustee, delivered a written notice to PTIF and Oi noting that the failure of PTIF to provide the 2014 audited financial statements constituted a potential event of default under the PTIF Bonds and requesting the delivery of those financial statements. PTIF is continuing to work with its auditor to complete the preparation of its 2014 audited financial statements as soon as possible.

The PTIF Trustee has notified PTIF that if PTIF fails to deliver the financial statements on or prior to May 29, 2016 and the PTIF Trustee determines that this failure is materially prejudicial to the interests of the holders of the PTIF Bonds, the PTIF Trustee could declare that the PTIF Bonds are immediately due and repayable. Under the terms of the PTIF Bonds, the PTIF Trustee is not obliged to exercise its discretion to declare any PTIF Bonds immediately due and repayable or to take any other action to enforce the rights of the holders of the PTIF Bonds unless it shall have been indemnified to its satisfaction and specifically directed or requested to do so by a requisite percentage of the holders of the PTIF Bonds in accordance with the terms and conditions of the PTIF Bonds.

The terms of the instruments governing a substantial portion of our indebtedness contain cross-acceleration clauses and if any series of the PTIF Bonds were accelerated, this acceleration would enable the creditors under other indebtedness to accelerate that indebtedness. Were a substantial amount of our outstanding indebtedness to be accelerated, we may not have sufficient funds to repay such debt when due.

ITEM 15.CONTROLS AND PROCEDURES

Disclosure ControlsDisclosureControls and Procedures

Our chief executive officer, or CEO, and our 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, 20132015 under the supervision of our CEO and our 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 our CFO concluded that our disclosure controls and procedures were not effective at a reasonable assurance level as of December 31, 2013.2015, 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 our CFO, our management conducted an assessment of the effectiveness of our internal control over financial reporting as of December 31, 20132015 based on the criteria established in “Internal Control —Integrated Framework (1992)(2013)” issued by COSO.

As a resultthe Committee of Sponsoring Organizations of the Treadway Commission. Based on this assessment, described above, our management concluded that as of December 31, 2013, we did maintain effective2015, our internal control over financial reporting basedwas 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 were:

Our financial statement closing process, including transformation of our statutory financial statements into U.S. GAAP consolidated financial statements, contains design and operating deficiencies severe enough that material errors may occur and may not be detected on a timely basis by management in the criteria establishednormal course of business.

We do not have sufficient and skilled accounting and finance personnel necessary to perform appropriate processes and controls to timely, consistently and appropriately identify, capture and analyze financially significant information in “Internal Control — Integrated Framework (1992)” issuedU.S. GAAP. As a result, audit adjustments were proposed and recorded by COSO.

us in order to properly reflect certain non-routine transactions in our U.S. GAAP financial statements.

Our independent registered public accounting firm, KPMG Auditores Independentes, has issued an audit reportadverse opinion on the effectiveness of our internal control over financial reporting. Thatreporting as of December 31, 2015 as stated in their report is included elsewherebeginning onpage F-3.

Remediation of Material Weakness

We have implemented and continue to implement measures designed to remediate the material weakness and, in the short term, to mitigate the potential adverse effects of this material weakness.

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 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 training session on U.S. GAAP matters for key members of our financial team, hiring external experts on U.S. GAAP to advise us on specific technical accounting of non-usual transactions, senior level accounting personnel for our U.S. GAAP department to allow implementing additional prevent and detect controls to improve annual report.financial statement closing process.

Pre-Approval Policies and Procedures

Our 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 our 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 our fiscal council and our board of directors, and (2) assess compliance with the pre-approval policies and procedures. Our management periodically reports to our fiscal council the nature and scope of audit and non-audit services rendered by our independent auditors and is also required to report to our fiscal council any breach of this policy of which our management is aware.

 

ITEM 16D.EXEMPTIONS FROM THE LISTING STANDARDS FOR AUDIT COMMITTEES

We are relying on the general exemption from the listing standards relating to audit committees contained inRule 10A-3(c)(3) under the Exchange Act for the following reasons:

 

we are 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 our fiscal council to be separate from our board of directors;

 

members of our fiscal council are not elected by our management, and none of our executive officers is a member of our fiscal council;

 

Brazilian law provides standards for the independence of our fiscal council from our management;

 

our fiscal council, in accordance with its charter, makes recommendations to our 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 our management and our independent auditors regarding financial reporting) for the purpose of preparing or issuing an audit report or performing other audit, review or attest services for our company, as Brazilian law requires that our board of directors appoint, retain and oversee the work of our independent public accountants;

 

our 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

 

our company compensates our independent auditors and any outside advisors hired by our fiscal council and provides funding for ordinary administrative expenses incurred by the fiscal council in the course of its duties.

We, however, do not believe that our reliance on this general exemption will materially adversely affect the ability of our 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 16G.CORPORATE GOVERNANCE

On November 4, 2003,According to the SEC approved the final corporate governance rules established byof the NYSE. According to these rules,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 Corporation Law, the rules of the CVM and the applicable rules of the BM&FBOVESPA, 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. However, under the NYSE corporate governance standards, aIn general, listed company (whether U.S or foreign) of which more than 50% of the voting power is held by another company (a “controlled company”), need notcompanies are required to comply with the following NYSE corporate governance standards:

 

a controlled company need not have a majority of independent directors;

a controlled company need not have a nominating/corporate governance committee composed of independent directors with a charter that complies with the NYSE corporate governance rules; and

a controlled company need not have a compensation committee composed of independent directors with a charter that complies with the NYSE corporate governance rules.

Because a majority of the voting power of Oi’s capital stock is directly controlled by TmarPart, Oi is a controlled company, and would therefore not be required to have a majority of independent directors if it were a U.S. domestic issuer.

Although Brazilian Corporation Law and Oi’s by-laws establish rules in relation to certain qualification requirements of its directors, neither Brazilian Corporation 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 Corporation Law, up to 1/3one-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. However, as a controlled company, Oi would not be required to comply with these requirements if it were a U.S. domestic company.

Oi isAlthough not required under Brazilian law, Oi has a People, Designation and Compensation Committee to have, and accordingly does not have, a nominating/corporate governance committee. Oi believes that, pursuant to its by-laws, the role of a nominating committee is generally performed by Oi’s board of directors and the role of the corporate governance committee is generally performed by eitherassist its board of directors, orwith the purpose of (1) supervising human resources strategies and attracting and retaining talent for Oi and its senior management.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.

Oi isAlthough not required under Brazilian law, Oi has a Corporate Governance and Finance Committee to have, and accordingly does not have, a compensation committee ofassist its board of directors. Under Brazilian Corporation Law,directors, with the purpose of: (1) monitoring the policies for corporate governance, maintaining the level of governance adopted by our Company 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 BM&FBOVESPA and other policies adopted by our Company, as well as other applicable legislation, regulations and foreign good practices, including, among others, conditions for maintaining Oi’s shareholders establishlisting on the aggregate compensationNYSE; 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 directors and executive officers, including benefits and allowances, at a general shareholder’s meeting based onsubsidiaries.

Oi believes that these committees substantially serve the recommendationfunctions of Oi’s boardthe committees required under NYSE corporate governance standards, although the terms of directors.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 sectionSection 10A-3(c)(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 Corporation 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 Corporation Law, CVM rules and the applicable rules of the BM&FBOVESPA 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 BM&FBOVESPA—BM&FBOVESPA 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 Corporation 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, 20132015 based on the criteria established in “Internal Control—Integrated Framework (1992)(2013)” issued by COSO.

As a result of themanagement’s assessment described above,of our management concluded that as of December 31, 2013, we did maintain effective internal control over financial reporting based onas of December 31, 2015, management concluded that the criteria establishedfollowing material weakness in “Internal Control—Integrated Framework (1992)” issued by COSO.our internal control over financial reporting existed:

Our independent registered publicfinancial statement closing process, including transformation of our statutory financial statements into U.S. GAAP consolidated financial statements, contains design and operating deficiencies severe enough that material errors may occur and may not be detected on a timely basis by management in the normal course of business.

We do not have sufficient and skilled accounting firm,and finance personnel necessary to perform appropriate processes and controls to timely, consistently and appropriately identify, capture and analyze financially significant information in U.S. GAAP. As a result, audit adjustments were proposed and recorded by us in order to properly reflect certain non-routine transactions in our U.S. GAAP financial statements.

Because of the existence of this material weakness, management has concluded that our internal control over financial reporting was ineffective as of December 31, 2015.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Report of Independent Registered Public Accounting Firm on Internal Control over Financial Reporting

To the Board of Directors and Shareholders of

Oi S.A.

Rio de Janeiro – RJ

We have audited Oi S.A.’s (the “Company”) internal control over financial reporting as of December 31, 2013,2015, based on criteria established in Internal Control — Integrated Framework (1992) (2013)issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Oi S.A.’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 Annual 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 conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). 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 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.

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 the accounting practices adopted in Brazil (BR GAAP), along with a reconciliation of net income and equity from BR GAAP to accounting principles generally accepted in the United States of America (“US GAAP”).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 BR GAAP along with a reconciliation of net income and equity from BR GAAP to US GAAPgenerally 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.

In our opinion, Oi S.A. maintained,A material weakness is a deficiency, or combination of deficiencies, in all material respects, effective internal control over financial reporting, as of December 31, 2013, based on the criteria established in Internal Control — Integrated Framework (1992) issued by the Committee of Sponsoring Organizationssuch that there is a reasonable possibility that a material misstatement of the Treadway Commission.company’s annual financial statements will not be prevented or detected on a timely basis. A material weakness related to the Company’s policies and procedures with respect to the preparation of financial statements in accordance with US generally accepted accounting principles has been identified and included in management’s assessment.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheetsheets of Oi S.A. and subsidiaries as of December 31, 20132015 and 2012,2014, and the related consolidated statements of income,operations, comprehensive income loss, changes in shareholders’ equity, and cash flows and value added for each of the years in the two-yearthree-year period ended December 31, 2013,2015.

This material weakness was considered in determining the nature, timing, and extent of audit tests applied in our audit of the 2015 consolidated financial statements, and this report does not affect our report dated March 10, 2014, expressedMay 19, 2016, which included an unqualified opinionexplanatory paragraph regarding the Company’s ability to continue as a going concern, on those consolidated financial statements.

/s/ KPMG Auditores Independentes                    In our opinion, because of the effect of the aforementioned material weakness on the achievement of the objectives of the control criteria, Oi S.A. has not maintained effective internal control over financial reporting as of December 31, 2015, based on the COSO criteria.

Going concern considerations

During 2015, our operations generated negative cash flows of R$1,054 million. As a result, we financed investing activities, debt service and profitworking capital from our cash and loss balancescash equivalents and short-term cash investments. Historically, 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.

As of December 31, 2015, our consolidated cash and cash equivalents and short-term cash investments amounted to R$16,700 million and our consolidated indebtedness amounted to R$ 59,857 million. We anticipated that we will be required to spend approximately R$19,725 million to meet our short-term contractual obligations and commitments during 2016, and an additional approximately R$30,672 million to meet our long-term contractual obligations and commitments in 2017 and 2018. As a result this financial situation doubt about Company’s ability to continue on a going concern basis.

Oi’s operating and business focus remains unchanged and Oi is still committed to continuing to make investments that ensure a continue improvement of its quality of service, which it believes will allow it to continue to bring technological advances to its customers all over Brazil. Oi also continues to undertake efforts for the operating upgrading and transformation of its business by focusing on austerity, infrastructure optimization, process revision, and sales actions.

On March 9, 2016, we announced that we had 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 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 Companybonds issued by Oi and its consolidated financial statements have been affectedsubsidiaries, as from the date the transaction was approved, on February 27, 2012, and with respect to profit or loss as from February 28, 2012, when it started to include the balances and transactions arising from the operationsan initial step towards discussions of TMAR anda potential restructuring of its subsidiaries.

Corporate Reorganization of the iG Group undertaken in October 2012

On October 24, 2012, our Board of Directors approved the corporate reorganization of the iG Group’s subsidiaries by undertaking the following steps: (i) BrTI capital increase, by the Company, amounting to R$51,828, paid in by transferring our stake in NTPA (99.99%), iG Participações (“iG Part”) (0.16%), and iG Brasil (13.64%); (ii) BrTI capital reduction, amounting to R$48,807, by transferring the investment held in BrT Multimídia to the Company, and (iii) mergers of iG Partindebtedness.

Should one of more of the assumptions underlying the Company cash flow projections and other forecasts, the financial support of the Company, or the outcome of the efforts to identify and implement financial and strategic alternatives to optimize the Company liquidity and debt profile not be met, this could be an indication of material uncertainties that would generate doubts as to the Company’s ability to realize its assets and settle its obligations at their carrying amounts, and as a result iG Brasil became a wholly-owned subsidiary of BrTI.

New Accounting Standards

Oi S.A.Long-Term Debt and SubsidiariesDebt Issuance Costs - In April 2015, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2015-03, “Interest – Imputation of Interest: Simplifying the Presentation of Debt Issuance Costs” (ASU 2015-03), which resulted in the reclassification of debt issuance costs from “Other Assets” to inclusion as a reduction of our reportable “Long-Term Debt” balance on our consolidated balance sheets. Since ASU 2015-03 does not address deferred issuance costs for line-of-credit arrangements, the FASB issued ASU No. 2015-15, “Interest – Imputation of Interest: Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements” (ASU 2015-15), in August 2015. ASU 2015-15 allows a company to defer debt issuance costs associated with line-of-credit arrangements, including arrangements with no outstanding borrowings, classify them as an asset, and amortize them over the term of the arrangements. We elected to adopt ASU 2015-03 early, with full retrospective application as required by the guidance. Adopting ASU 2015-03 resulted in the reclassification of approximately R$473,800 from other assets to loans and financing within the consolidated balance sheets as of December 31, 2014.

NotesDeferred Income Taxes and Liabilities - In November 2015, the FASB issued ASU No. 2015-17, “Income Taxes (Topic 740) – Balance Sheet Classification of Deferred Taxes” (ASU 2015-17), which requires companies report their deferred tax liabilities and deferred tax assets, together as a single noncurrent item on their classified balance sheets. The Company elected to early adopt the new standard for the current reporting period, which is permitted, and applied a retrospective transition method. Adopting ASU 2015-17 resulted in the reclassification of R$1,631,155 from current to noncurrent deferred income tax assets within the consolidated balance sheets as of December 31, 2014.

Revenue Recognition - In May 2014, the FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers (Topic 606)” (ASU 2014-09) and has since modified the standard with ASU 2015-14, “Deferral of the Effective Date”, ASU 2016-08 “Principal versus Agent Considerations (Reporting Revenue Gross versus Net)” and ASU 2016-10 “Identifying Performance Obligations and Licensing”. These standards replace existing revenue recognition rules with a comprehensive revenue measurement and recognition standard and expanded disclosure requirements. ASU 2014-09 becomes effective for annual reporting periods beginning after December 15, 2018, at which point we plan to adopt the standard. Upon initial evaluation, we believe the key changes in the standard that impact our revenue recognition relate to the Financial Statementsallocation of contract revenues between various services and equipment, and the timing in which those revenues are recognized. We are still in the process of determining the impact on the timing of revenue recognition and the allocation of revenue to products.

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 Years Endedability 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 our consolidated balance sheet as of December 31, 2013, 20122015, or our consolidated operating results and 2011

Commission (CVM)Leases (Topic 842) - In February 2016, the FASB issued ASU 2016-02 which supersedes FASB ASC Topic 840, Leases, and incorporatesmakes 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 statementsstatements.

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 sales prices of its goods and services;

 

the costs of services and sales;

 

the cash flows arising from receipts from customers and payments to suppliers;

 

interest, investments and financing.

Consequently, the functional currency of the Company and its subsidiaries is the Brazilian real (R$), the same currency used in the presentation of these financial statements.

Completing the software so that it will be available for use is technically feasible.

Management has the intention to complete the software and use or sell it.

It can be demonstrated that the software will generate probable future economic benefits.

There are adequate technical, financial and other resources available to complete the development and to use or sell the software.

The expenditure attributable to the software during its development can be measure reliably.

Directly attributable costs that are capitalized as part of software include the costs on the employees allocated to software development and an adequate portion of the applicable direct expenditure. Costs also include borrowings costs incurred during the software development period.

Other development expenditure that does not meet these criteria is recognized as expenses, when incurred. Development costs previously recognized as expenses are not recognized as assets in a subsequent period.

Impairment of long-lived assets

Assets are testedreviewed for impairment annually or 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 of assets might be impaired. Long-lived assets maytested for possible impairment, the Company first compares undiscounted cash flows expected to be identified as assetsgenerated by that have indefinite useful lives and assets subjectasset or asset group to depreciation and amortization (property, plant and equipment and intangible assets). Impairment losses, if any, are recognized in the amount by whichits carrying amount. If the carrying amount of the long-lived asset or asset group is not recoverable on an assetundiscounted cash flow basis, an impairment is recognized to the extent that the carrying amount exceeds its recoverablefair value. RecoverableFair value is the higher of fair value less cost to sell and the value in use. In order to be tested for impairment, assets are grouped into the smallest identifiable group for which there are cash-generating units (CGUs), and projections are made based ondetermined through various valuation techniques including discounted cash flows, supported by expectations on the Company’s operations.

The CGUs are the Company’s operating segmentsflow models, quoted market values and third-party independent appraisals, as they are the smallest separable cash-generating units.

Net Present Value (NPV) projections for the CGUs are prepared taking into consideration the following assumptions:

Entity-specific inputs: evidence of obsolescence or damage, discontinuation plans, performance reports, etc.;

External sources of inputs: market prices of the assets, technologic environment, market environment, economic environment, regulatory environment, legal environment, interest rates, return rates on investments, market value of Company shares, etc.

Said projections support the recovery of assets with indefinite useful lives. Additionally, Company tests did not show any evidences of impairment that would result in the realization of projections for assets with finite useful lives.

Discount to present value

The Company values its financial assets and financial liabilities to identify instances of applicability of the discount to present value. Leased assets are discounted to present value.

Generally, when applicable, the discount rate used is the average return rate on investments for financial assets or interest charged on Company borrowings for financial liabilities. The balancing item is the asset or liability that has originated the financial instrument, when applicable, and the deemed borrowing costs are allocated to the Company’s profits over the transaction term.

The Company believes that none of the assets and liabilities as at December 31, 2013 and 2012 is subject to the discount to present value, in view of the following factors: (i) their nature; (ii) short-term realization of certain balances and transactions; (iii) absence of monetary assets and monetary liabilities with observable or unobservable embedded interest. Financial instruments measured at the amortized costs are adjusted for inflation using relevant contractual indices.

Impairment of financial assets

The Company assesses at the yearend whether there is objective evidence that financial assets or a group of financial assets is impaired. A financial asset or group of financial assets is considered impaired when there is objective evidence, as a result of one or more events that occurred after the initial recognition of the asset, that its recoverable amount has been reduced and when the estimated future cash flows have been impacted.

In the case of equity investments classified as available for sale, a significant or prolonged decline in their fair value below cost is also objective evidence of impairment.

Borrowings and financing

Carried at amortized cost, plus inflation adjustment or foreign exchange differences and interest incurred through the end of the reporting period.

Transaction costs incurred are measured at amortized cost and recognized in liabilities, as a reduction to the balance of borrowings and financing, and are expensed over the relevant agreement term.necessary.

Employee benefits

Pension plans: 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.
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.

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.

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.

Revenue is recognized when it can be reliably measured, it is probable that future economic benefits will be transferred to the Company, the transaction costs incurred can be measured, the

risks and rewards have been substantially transferred to the buyer, and certain specific criteria of each of the Company’s activities have been met.

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.

Revenue from sales of payphone cards–Public Use Telephony (TUP)—is recognized when the credits are effectively consumed by the customers.

Customer loyalty program (“Oi Pontos”)

The subsidiaries Oi Móvel and TNL PCS implemented a customer loyalty program (“Oi Pontos”), under which mobile telephony customers accumulate points related to the amounts paid for mobile telephony, fixed telephony, internet and pay TV services, which can be exchanged for mobile telephony service packages, handset discounts, events available at “Oi experiences” and/or transferred to the Multiplus Fidelidade Program (partner of said subsidiaries) to be exchanged for several other awards of this program, such as air tickets, fuel in gas stations, etc.

The Company accounts for the points awarded under the program as a separately identifiable component of the sales transaction in which they are granted. The fair value of the consideration received or receivable in respect of the initial sale is allocated between the award credits and the other components of the sale. The consideration allocated to the points is measured by reference to their fair value, i.e., the amount for which the award credits could be sold separately. This amount is deferred and the related revenue is recognized when, and only when, the points are redeemed or transferred to partner programs. Revenue recognition is based on the number of points that have been redeemed in exchange for awards relative to the total number expected to be redeemed. This program began its effective operations in the first quarter of 2011 and its balance is recognized in liabilities, in line item ‘Unearned revenues’.

Expense recognition

Expenses are recognized on thean accrual basis, considering their relation with revenue realization. Prepaid expenses attributable to future years are deferred over the related periods.

Any write-down to deferred tax assets is reversed when it is probable that sufficient taxable income will be available.

Deferred tax assets and liabilitiespositions are measured usingat the tax rates applicable forlargest amount that is greater than 50 percent likely of being realized. Changes in recognition or measurement are reflected in the period in which the liability is expected to be settled or the asset is expected to be realized, based on thechange in judgment occurs.

The measurement of deferred tax assets and liabilities reflects the tax consequences that would follow from the mannerall jurisdictions in which they do business (Brazil is the Company expects, at the end of each reporting period,only major tax jurisdiction). In Brazil, income tax returns are subject to recover or settle the carrying amount of these assets and liabilities.

Government grants and government assistance

Government grants are initially recognized as deferred revenue at fair value when there is reasonable assurance that they will be received and that the Company will comply with the conditions attaching to them. Government grants received as compensation for Company’s expenses incurred are recognized as income on a systematic basis in the same periods when such expenses are recognized, and grants received as compensation for the cost on an asset are recognized as income on a systematic basis over the useful life of the asset.

Earnings per share

Basic earnings per share are calculated using profit for the period attributable to the owners of the Company and noncontrolling interests and the weighted average number of common and preferred shares outstanding in the period. Diluted earnings per share are calculated using said weighted average number of outstanding shares adjusted by potentially dilutive convertible instruments in the reporting periods, pursuant to CPC 41.

The statementDecember 31, 2015 the company has no unrecognized tax benefits, nor any interest and penalties thereon.    Interest and penalties on an underpayment of cash flows is prepared in accordance with CPC03 (R2), under the indirect method. The Company classifies in line item ‘Cash and cash equivalents’ the balances amounts immediately convertible into cash and highly-liquid investments (usually with maturitiesincome taxes are recognized as part of less than three months) subject to an immaterial risk of change in value.

Cash flows are classified in the statements of cash flows, depending of their nature, as (i) operating activities; (ii) investing activities; and (iii) financing activities. Cash flows arising from operating activities basically comprise trade receivables, trade payables, personnel expenses, financial charges, and losses on lawsuits. Cash flows arising from investing activities basically comprise the acquisition and disposal of investments, escrow deposits and withdrawals, and cash payments and cash receipts from the purchase and sale of property, plant and equipment, intangiblesinterest expense and other long-term assets. Cash flows arising from financing activities basically comprise cash payments and cash proceeds related to borrowings and financing, loans, derivatives, and dividends and interest on capital.

(d)Critical estimates and accounting judgments

In preparing the financial statements, 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. The estimates that represent a significant risk of causing material adjustments to the carrying amounts of assets and liabilities are as follows:

Revenue recognition and trade receivables

The Company’s revenue recognition policy is significant as it is a material component of operating results. Pricing undertaken by management, collection ability, and the right to receive certain network usage revenue are based on judgment related to the nature of the tariff collected for the services provided, the price of certain products, and the right to collect this revenue. If changes in conditions cause management to conclude that such criteria are not met in certain operations, the amount of trade receivables might be affected. In addition, the Company depends on guidelines to measure certain revenue set by the ANATEL (Brazilian telecommunications industry regulator).

Allowance for doubtful accounts

The allowance for doubtful accounts is set to recognize probable losses on receivables, as described in Note 2, taking into account the actions taken to restrict the provision of services to and collect default customers.

Oi S.A. and Subsidiaries

Notes to the Financial Statements

for the Years Ended December 31, 2013, 2012 and 2011

(Amounts in thousands of Brazilian reais, unless otherwise stated)

The Company’s management includes government entities, corporate customers, and other providers of telecommunications services in the base to calculate the allowance. 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.

Depreciation and amortization of assets with finite useful lives

Property, plant and equipment items and intangible assets with finite useful lives are depreciated and amortized, respectively, on a straight-line basis, over the useful life of the related asset. The depreciation and amortization rates of the most significant assets are shown in Notes 15 and 16,expenses, respectively.

The useful lives of certain assets may vary as they are used in the fixed-line or mobile telephony segments. The Company reviews the useful lives of assets on annual basis.

Impairment of long-lived assets

The Company tests property, plant and equipment items and intangible assets for impairment either in light of decisions to discontinue activities where such assets are used or when there are evidences that the future operating revenue will not be sufficient to assure their realization.

Assets with finite useful lives are tested for impairment whenever events or changes in circumstances indicate that the asset might be impaired. The Company tests assets with indefinite useful lives (goodwill) for impairment annually in accordance with the accounting policy described in note 2 (b).

The recoverable amounts of assets are determined by comparing the calculations of their value in use and their sales prices. These calculations require the use of judgments and assumptions. The determination of fair values and discounted future operating cash flows requires that the Company makes certain assumptions and estimates with respect to projected cash inflows and cash outflows related to future revenue, costs and expenses. These assumptions and estimates may be influenced by different 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 the Company to the market. The use of different assumptions can significantly change our financial statements.

Provisions

The Company recognizes provisions for losses in labor, tax and civil lawsuits, as administrative proceedings, as presented in Note 22. The recognition of a provision for contingent liabilities is based on the assessment of the risk of loss made for each proceeding, which includes assessing available evidences recent decisions and statistical assumptions, and reflects a reasonable estimate as assessed by management, the General Counsel, and the outside legal counsel. It is possible that the assumptions used to estimate the provision for contingent liabilities change, which can, therefore, result in changes in future provisions for contingent liabilities.

(Amounts in thousands of Brazilian reais, unless otherwise stated)

Derivative instruments

Derivative financial instruments are recognized at fair value based on future cash flow estimates associated to each instrument contracted. The estimates presented 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 could have a material effect on the amounts obtained and not necessarily be indicative of the cash amounts that the Company would receive or to settle such transactions.

Deferred income tax and social contribution

The Company recognizes and settles taxes on income based on the results of operations determined in accordance with the Brazilian corporate law, taking into consideration the provisions of the tax law, which are materially different from the amounts calculated for CPC purposes. Pursuant to CPC 32, the Company recognizes deferred tax assets and liabilities based on the differences between the carrying amounts and the taxable bases of the assets and liabilities.

The Company regularly tests deferred tax assets for impairment and recognizes an allowance 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 calculations require the use of estimates and assumptions. The use of different estimates and assumptions could result in the recognition of an allowance for impairment losses for the entire or a significant portion of the deferred tax assets.

Employee benefits

The actuarial valuation is based on assumptions and estimates related to interest rates, return on investments, inflation rates for future periods, mortality indices, and an employment level projection related the pension fund benefit liabilities. The accuracy of these assumptions and estimates will determine the creation of sufficient reserves for the costs of accumulated pensions and healthcare plans, and the amount to be disbursed annually on pension benefits. These assumptions and estimates are subject to significant fluctuations due to different internal and external factors, such as economic trends, social indicators, and our capacity to create new jobs and retain our employees. All assumptions are reviewed at the end of the reporting period. If these assumptions and estimates are not accurate, there may be the need to revise the reserves for pension benefits, which could significantly impact Company results.

3.2. Fair value of financial instruments

The Company and its subsidiaries have measured their financial assets and financial liabilities at their market or actual realizable values (fair value)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 obtained.amounts.

 

(a)Derivative financial instruments

The method used for calculation ofcalculating the fair value of derivative financial instruments was the future cash flows associated to each instrument contracted, discounted at market rates prevailing at December 31, 2013.2015.

 

(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.

Oi S.A. and Subsidiaries

Notes to the Financial Statements

for the Years Ended December 31, 2013, 2012 and 2011

(Amounts in thousands of Brazilian reais, unless otherwise stated)

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.

 

(c)Fair value measurement hierarchy

CPC 46 defines fairFair value asis 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 standard clarifies that the fair value mustis be based on the assumptions that market participants would consider in pricing an asset or a liability, and establishesin 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 standard requires that an entity considerCompany considers all nonperformance risk aspects, including the entity’s credit, when measuring the fair value of a liability.

CPC 40 establishes a three-level hierarchy

Notes to measurethe Financial Statements

for the years ended December 31, 2015, 2014 and disclose fair value. 2013

(In thousands of Brazilian reais - R$, unless otherwise stated)

The classification of an instrument in the fair value measurement hierarchy is based on the lowest level of input significant for its measurement. We present below a description of the three-level hierarchy:

Level 1—inputs consist of (unadjusted) 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 levelLevel 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 and/or allocations to Level 3 between December 31, 20132015 and December 31, 2012.2014.

Accounts receivables: near-term maturity of bills.

 

Trade payables, dividends and interests on capital: all obligations are due to be settled in the short term.

3.4. Financial risk management

3.3.Financial risk management

The Company’s and its subsidiaries’ activities exposean exposed them to several financial risks, such as: market risk (including currency fluctuationvariation risk, interest rate risk on fair value, interest rate risk on cash flows, and price risk), credit risk, and liquidity risk. The Company and its subsidiaries use derivative financial instruments to protect them againstmitigate certain exposures to these risks.

Risk management is carried out by the Company’s treasury officer, in accordance with the policies approved by management.

The Hedging and Cash Investmentsinvestments 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.

Under the Hedging Policy,Company policies, market risks are identified based on the features of financial transactions contracted and to be contracted during the year. Several scenarios are then simulated for each of the risk factors using statistical models, used as basis to measure the impacts the on Group´sGroup’s financial income (expenses). The Board of Directors meeting of January 2016 widened this concept, to also monitor impacts on Group’s financial cash flow, gross debt and net debt. Based on this analysis, the Executive Committee annually agrees with the Board of Directors the Risk Guidelinea guideline to be followed in each financial year. The Risk Guideline is equivalent to the worst expected impact of financial income (expenses) on the Group’s net income, with 95% of level of confidence.

To ensure a proper risk management, according to the Risk Guideline, the treasuryCompany can contract and reverse hedging instruments, including derivative transactions such as swaps and currency forwards. The contract of such instruments depends on, among other factors, available funds within the credit limit set by banks. The Company and its subsidiaries do not use derivative financial instruments for other purposes.

With the approval of the Policies, a Financial Risk Management Committee that meets monthly was created, currently consisting of the CEO, the CFO, the Executive Planning Officer, the Development

and New Business Management Officer, the Tax Officer, the General Controller, and the Treasury Officer, and the Internal Audit Officer as observer.

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.

Foreign currency-denominated cash equivalents and cashshort-term investments are basically maintained in securities issued by financial institutions abroad similar to Bank Certificates of Deposit trade(CDBs) traded in Brazil (time deposits), and euro-denominated time deposits and United States dollars (“dollar” or “dollars”).

The risk associated to these assets arises from the possible exchange rate fluctuationschanges that may reduce the balance of these assets when translated into Brazilian reais. The Company’s and its subsidiaries’ assets subject to this risk represent approximately 13.25% (6.71%73.22% (11.41% at December 31, 2012)2014) of our total cash and cash equivalents and cashshort-term investments.

Financial liabilities

The Company and its subsidiaries have foreign currency-denominated or foreign currency-indexed borrowings and financing. The risk associated with these liabilities is related to the possibility of fluctuationschanges in foreign exchange rates that could increase the balance of such liabilities. The Company’sCompany and subsidiaries’subsidiaries borrowings and financing exposed to this risk represent approximately 41.1% (39.1%78.5% (41.7% at December 31, 2012)2014) of total liabilities from borrowings and financing, less the contracted currency hedging transactions contracted.transactions. In order to minimize this type of risk, we enter into foreign exchange hedges with financial institutions. Out of the consolidated foreign currency–denominated debt, 99.6% (97% at December 31, 2012) is protected by exchange swaps, currency forwards, and cash investments in foreign currency. The unrealized gains or losses on hedging transactions are measured at fair value, as described in (a) above.

(b)Interest rate risk

Financial assets

Cash equivalents and cashshort-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.

Financial liabilities

The Company and its subsidiaries have borrowings and financing subject to floating interest rates, based on the Long-term Interest Rate (TJLP) or the CDI, in the case of real-denominated debt, and on the LIBOR, in the case of U.S. dollar-denominated debt.

(Amounts in thousands of Brazilian reais, unless otherwise stated)

As at December 31, 2013,2015, approximately 63.2% (65.4%33.4% (60.3% at December 31, 2012)2014) of the incurred debt, less adjustment for derivative transactions, was subject to floating interest rates. After the derivative transactions, approximately 76.0% (70.3%59.6% (79.4% at December 31, 2012)2014) of the consolidated debt was subject to floating interest rates. The most material exposure of Company’s and its subsidiaries’ debt after the hedging transactions is to CDI. Therefore, a continued increase in this interest rate would have an adverse impact on future interest payments and hedging adjustments. However, as the Company’s and its subsidiaries’ cash is invested mainly in securities pegged to the CDI fluctuation, the net exposure to CDI of current liabilities does not constitute a material risk for the Company and its subsidiaries.

We continuously monitor these market rates to assess the possible contracting of instrumentsderivatives to hedge againstreduce the risk of fluctuation of these rates.

Interest rate swaps

US$ LIBOR/US$ fixed rate: Refer to interest rate swaps to protect debt payments peggedassociated to US dollar floating rates from exchange fluctuation. Under these contracts, the asset position in US dollar LIBOR and the liability position is a fixed rate. The risk of loss in the asset position of these instruments is, therefore, the fluctuation of the US dollar LIBOR; however, such possible losses would be fully offset by maturities of USdollar-denominated debt peggedassociated to LIBOR.

US$ fixed rate/US$ LIBOR: Refers to the interest rate swap transaction that changes US dollar-denominated debt payments from fixed rate to floating rate. Under this contract, the asset position is a US dollar fixed rate and a LIBORthe liability position is subject to reduceLIBOR aimed at reducing the cost of the backingunderlying debt, as part of the Company’s onerous liabilityinterest-bearing liabilities management strategy.

(In thousands of Brazilian reais - R$, unless otherwise stated)

 

(b.1)Interest rate fluctuation risk sensitivity analysis

Management believes that the most significant risk related to interest rate fluctuations arises from its liabilities peggedassociated to the TJLP, the USD LIBOR, and mainly the CDI. This risk is associated to an increase in those rates.

As at December 31, 2013,2015, management estimated the fluctuation scenarios of the rates DI,CDI, TJLP and USD LIBOR. The rates used for the probable scenario were the rates prevailing at the end of the reporting period. These rates have been stressed by 25 and 50 percent, and used as benchmark for the possible and remote scenarios. NoteImportant to consider that in the beginning of January 2015, the TJLP has remained stable since July 2009 at 6% per year. This rate droppedincreased from 5.0% p.a. to 5.5% p.a., which was the start of successive increases. For the quarter beginning April 2015, the TJLP increased to 6.0%, remaining at 6.5% in July 2012 and in October 1-December 31, 2015 it increased to 5.0% per year7.0%.

Before the end of the first quarter of 2016, the National Monetary Council had decided for a new increase for this rate, this time to 7.5% p.a., effective in December de 2012, and remained at 5.0% per year until December 2013.January 1 - March 31, 2016.

As at December 31, 2013,2015, management estimated the future outflows for the payment of interest and principal of its debt peggedassociated to CDI, TJLP, and US$USD LIBOR based on the interest rates above. The outflows for repayment of Oi Group related party debt were not considered.

Such sensitivity analysis considers payment outflows in future dates. Thus, the aggregate of the amounts for each scenario is not equivalent to the fair values, or even the present values of these liabilities. The fair values of these liabilities, should the Company’s credit risk remain unchanged, would not be impacted in the event of fluctuations in interest rates, as the interest rates used to estimate future cash outflows would be the same rates that discount such flows to present value.

The impacts of exposure to interest rates, in the sensitivity scenarios estimated by the Company, are shown in the table below:

3.4.2. Credit risk

3.4.2.Credit risk

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(short-term 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. As at December 31, 2013,2015, approximately 98.6%99.20% of the consolidated cashshort-term investments were made with counterparties with aan AAA, AA or sovereign risk rating.

3.4.3. Liquidity riskThe Company had credit risks related to dividends receivable associated to the investment in Unitel (Note 26).

3.4.3.Liquidity risk

The liquidity risk also arises from the possibility of the Company being unable to dischargesettle its liabilities on maturity dates and obtain cash due to market liquidity restrictions.

Management uses its resources mainlyDuring 2015, our operations generated negative cash flows of R$1,054 million. As a result, we financed investing activities, debt service and working capital from our cash and cash equivalents and short-term cash investments. Historically, 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.

As of December 31, 2015, our consolidated cash and cash equivalents and short-term cash investments amounted to fund capital expenditures incurred on the expansionR$16,700 million and upgradingour consolidated indebtedness amounted to R$ 59,857million. We anticipated that we will be required to spend approximately R$19,725 million to meet our short-term contractual obligations and commitments during 2016, and an additional approximately R$30,672 million to meet our long-term contractual obligations and commitments in 2017 and 2018.

On March 9, 2016, we announced that we had 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 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 network, invest in new businesses, pay dividends,bonds issued by Oi and refinance its debt.subsidiaries, as an initial step towards discussions of a potential restructuring of its indebtedness.

The financial statements for the year ended December 31, 2013 have been prepared considering management’s best estimates and the criteria set out in the Transitional Tax Regime (RTT).

Management conducted an initial valuation of the material aspects of its operations/businesses, based on the provisions of Provisional Act 627, of November 11, 2013 (“MP 627/2013”) and Regulatory Instruction 1397, of September 16, 2013, as amended by Regulatory Instruction 1422, of December 19, 2013 (“IN 1397/2013”).

Even though MP 627/2013 becomes effective on January 1, 2015, it offers an early adoption option (irrevocable), beginning January 1, 2014.

Management has not yet decided whether or not it will make the early adoption option since: (i) MP 627/2013 still has to be regulated; (ii) MP 627/2013 could be significantly amended in light of the several amendments proposed, including as regards the effects arising from its early adoption; (iii) to date no statute has been issued setting the deadline and method to early adopt the effects of MP 627/2013; and (iv) the adjustments to the financial statements as a result of the non-early adoption have not yet been determined.

(v)In 2014, the main effects are linked to goodwill amortization (pre-merger period), settlement of principal, fine and interest utilizing tax loss carryforwards as permitted by Article 2 of Law 12996/2014 and Article 33 of Law 13043/2014.
(vi)These tax incentives correspond mainly to a 75% reduction in the current income tax due on operating income obtained as a result of telecommunication services rendered in certain northern and northeast regions of Brasil, 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.
(vii)Refers to uncertain tax position taken in prior periods which were assessed by the taxing authorities. Although the Company believed in prior periods that these positions would be more-likely-than-not of being sustained, it has 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 of 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.

The deferred tax assets not offset by valuation allowance are dependent upon the generation of future pretax income in certain of our tax-paying components in Brazil that have a history of profitability and an expectation of continued profitability.

In February 2012, the Company issued senior notes in the amount of US$1,500 million (R$2,741 million) to refinance its debt and for general corporate purposes. The final maturity of these notes is February 2022. On July 27, 2012 the Company transferred this issue to its wholly-owned subsidiary Oi Brasil Holdings Cooperatief, through a supplementary indenture, net of debt issuance costs. The related debt issuance costs, totaling R$12 million (US$6 million), will be amortized through profit or loss, according to this issuance’s contractual terms, using its effective interest rate.

Pursuant to our legal counsel’s assessments and based on more complete historic information, we revised the likelihood of unfavorable outcome of a set of labor lawsuits to which the Company is jointly and severally liable to remote, resulting in a decrease in the previously recognized amount.

We revised the methodology used to calculate the provisions for losses in civil lawsuits—corporate lawsuits involving the financial participation agreements, including statistical techniques, as a result of the higher experience accumulated in the matter. The change in estimates generated a R$325,709 reversal in the provisions for civil contingencies—corporate, recognized in other operating income (expenses), net.

Civil

 

(i)Corporate – Financial Participation Agreements - these agreements were governed by Administrative Rules 415/1972, 1181/1974, 1361/1976, 881/1990, 86/1991, and 1028/1996. Subscribers held a financial interest in the concessionaire after paying in a certain amount, initially recorded as capitalizable funds and subsequently recorded in the concessionaire’s equity, after a capital increase was approved by the shareholders’ meeting, thus generating the issuance of shares. The lawsuits filed against the former CRT - Companhia Riograndense de Telecomunicações, a company mergedacquired by the Company, challenge the way shares were granted to subscribers based on said financial participation agreements.

The Company used to recognize a provision for the risk of unfavorable outcome in these lawsuits based on certain legal doctrine. In the first half ofDuring 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 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, and (iii) the average amount of historical losses, broken down by matter in dispute. 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

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 the company’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, 2013,2015, had these criteria already been adopted. There may be, however, significant changes in the items above, mainly regarding the market price of Company shares.

 

(ii)ANATEL estimates - referrefers basically to alleged noncompliance with General Universal Service Targets Plan (“PGMU”) and, General Quality Targets Plan (“PGMQ”) obligations;

(iii)ANATEL fines - They largely refer to provisions for fines arising from failures to meet quality targets under the terms of the Inspection Procedures of Noncompliance with Obligations (“PADOs”) of the PGMQ, and the Quality Indicators Regulation (“RIQ”). obligations;

In December 2013, ANATEL approved Resolution 629/2013, which approves the Regulation for the execution and monitoring of the Policy Adjustment Agreements (TAC). The TAC that allow telecommunications operators to request, in the context of proceedings for which no final and unappealable decision has been issued at the administrative level by ANATEL, that such fines be settled through investments in infrastructure, with additional incentives for projects in underdeveloped areas or through direct benefits to consumers, as well as the revision of the policies that resulted in said fines. In April 2015, Oi filed a proposal containing (a) corrective actions for approximately 500 policies that covers almost all the main reasons for the regulatory penalties imposed by ANATEL and (b) an “additional commitment” to offset Oi’s contingencies falling within the scope of the TAC.

Since then, ANATEL is assessing and discussing the content of this proposal with Oi, in compliance with the formalities provided for under the TAC, to meet the premises that drove the approval of this Regulation. Currently, the TAC negotiation process is at its final stage and we expect to sign the agreements on Universal Service and Quality targets in the coming months. Up to December 31, 2015, the proceedings being judged by ANATEL and discussed in the context of the TAC totaled approximately R$5 billion, consisting of fines at several procedural stages—approximately R$3 billion in fines imposed and R$2 billion in estimated fines.

If Oi fails to comply with its commitments set forth in the TAC or discharge the obligations established by ANATEL regulations, it will be subject to penalties, such as: warnings, fines, and, in a worst case scenario, ANATEL’s intervention, temporary suspensions of services, or cancellation of its concessions and licenses. If the TAC does not provide for a specific policy, the related administrative proceeding returns to the ordinary review proceeding, where Oi will discuss with ANATEL its nature and amounts involved, as well as the implementation of corrective measures, if necessary.

In 2015, ANATEL revised the penalization methodologies concerning the main types of infractions, notably User Rights and Guarantees, Quality (targets and indicators), and Station Licensing, and initiated a Public Hearing process for the revision of the Universal Service and Barriers to Inspections methodologies. Oi and the other industry players contributed to the Public Consultations conducted by ANATEL on these matters by emphasizing the need for improvement that can contribute to penalty fairness that ensures the educational nature of penalties and the economic feasibility of the operators, thus reducing disputes in courts and favoring the expansion of industry investments. As at December 31, 2015, the Company had fines outside the jurisdiction of ANATEL that were determined under the former penalty calculation methodology and are being discussed in courts. The Company disagrees and is challenging some of the alleged noncompliance events, and is also challenging the unfairness of the amount of some imposed fines in light of the pinpointed noncompliance event.

(h)Basic and diluted earnings per share

The Company’s bylaws award different rights to common and preferred shareholders with respect to dividends, voting rights, and in case of liquidation of the Company. Accordingly, basic and diluted earnings per share were calculated based on profit for the year available to common and preferred shareholders.

Basic

Basic earnings per share are calculated by dividing the profit attributable to controlling shareholders, available to common and preferred shareholders, by the weighted average number of common and preferred shares outstanding during the year.

Diluted

Diluted earnings per share are calculated by adjusting the weighted average number of outstanding common and preferred shares, to estimate the dilutive effect of all convertible securities. Currently we do not have any potentially dilutive shares.

The table below shows the calculations of basic and diluted earnings per share:

ADDITIONAL DISCLOSURES – 2013

a)Plans’ assets and liabilities correspond to the amounts as at December 31, 2013.

b)Master file data used for the SISTEL plans are as at July 31, 2013 and for PAMEC are as at October 31, 2013, projected for December 31, 2013.

The amounts above do not consider the assets and liabilities of the PAMA plan because it is multi-sponsored and similar to defined contribution plans (benefits paid are limited to the amount of the contributions received by the plan), and there are no other obligations in addition to the existing balances.

Investment policy of the plans

The investment strategy of the benefit plans is described in their investment policy, which is annually approved by the governing board of the sponsored funds. This policy establishes that investment decision-making must take into consideration: (i) the preservation of capital; (ii) the diversification of investments; (iii) the risk appetite according to conservative assumptions; (iv) the expected return rate based on actuarial requirements; (v) the compatibility of investment liquidity with the plans’ cash flows, and (vi) reasonable management costs. The policy also defines the volume interval for different types of investment allowed for the pension funds, as follows: local fixed income, local variable income, loans to participants, and real estate investments. The fixed income portfolio can only include low credit risk securities. Derivatives are only allowed for hedging purposes. Loans are restricted to certain credit limits. Tactical allocation is decided by the investment committee consisting of the benefit plans’ executives. Execution is undertaken by the finance department.

(b)Employee profit sharing

In the yearyears ended December 31, 2013, the Company2015, 2014 and its subsidiaries recognized a partial reversal of the accrued employee profit sharing bonuses, net of the amounts accrued for the current year, totaling R$112,448 (see Note 6).

This reversal was recognized in accounting by decision of the Board of Directors and after analyzing the achievement of the targets set.

(c)Share-Based compensation plan

The Company requested CVM’s approval of the transfer of Company treasury shares, specifically as regards the shares linked to the Special Long-term Bonus Program, as prescribed by Article 2 of CVM Instruction 10/1980. On December 3, 2013 CVM’s board unanimously decided to (i) authorize the transfer of Company treasury share to the Long-term Incentive (ILP) beneficiaries, provided that all the requirements of CVM Instruction 10/1980 were met, and (ii) require the approval of the Company’s ILP plan at a shareholders’ meeting. However, in light of the new corporate configuration that can result in implementing a union of the Company’s activities with the activities of Portugal Telecom, the Company is considering redesigning its share-based compensation plan.

Memorandum of understanding for the merger of the activities of Oi S.A. and Portugal Telecom

On October 2, 2013 Oi published a Material Fact Notice informing that Oi, Portugal Telecom, SGPS S.A. (“Portugal Telecom”), AG Telecom Participações S.A. (“AG”), LF Tel. S.A. (“LF”), PASA Participações S.A. (“PASA”), EDSP75 Participações S.A. (“EDSP75”), Bratel Brasil S.A. (“Bratel Brasil”), Avistar, SGPS, S.A. (“BES”), and Nivalis Holding B.V. (“OnGoing”) entered into a memorandum of understanding that lays down the bases and the principles that will govern the negotiations for a potential transaction involving Portugal Telecom, Oi, and some of their controlling shareholders to incorporate a company (“CorpCo”) that will consolidate the industrial alliance between Oi and Portugal Telecom.

CorpCo, which could be Telemar Participações S.A. (“TelPart”) or any other entity incorporated for this purpose, will join the shareholders of Oi, Portugal Telecom and TelPart, and combine the activities and businesses currently undertaken by Oi in Brazil and Portugal Telecom in Portugal and Africa. The business combination between Portugal Telecom and Oi will create a multinational telecom operator, reaching a population of approximately 260 million people and more than 100 million customers. The transaction will consolidate both companies’ position as leading operator in the Brazilian and Portuguese markets. The combination of the two groups aims at achieving significant economies of scale, maximizing operational synergies, and create value for their shareholders, customers, and employees.

The transaction involves several, interdependent steps, including the following:

(a) The increase of Oi’s capital by no less than R$13.1 billion, with the goal of reaching R$14.1 billion, through the public issuance of Oi common and preferred shares, of which a minimum of R$7 billion, aimed at reaching R$8.0 billion, will be paid-in in cash, and approximately R$6.1 billion will be paid in by Portugal Telecom, at the same share price, through a contribution of Portugal Telecom assets;

(b) Capitalization of AG, LF and TelPart with the funds required to repay their debts;

(c) A corporate reorganization involving the companies PASA, AG, EDSP75, LF, Bratel Brasil, and TelPart to streamline their corporate structure. After this step, TelPart will become the holder of Oi shares only, either directly or through Valverde Participações S.A., and will not have any debt or have sufficient cash or cash equivalents to repay its debt;

(d) Listing of CorpCo on theNovo Mercado Segment of the BM&FBOVESPA and termination of AG’s, LF’s and TelPart’s shareholders’ agreements;

Oi S.A. and Subsidiaries

Notes to the Financial Statements

for the Years Ended December 31, 2013, 2012 and 2011

(Amounts in thousands of Brazilian reais, unless otherwise stated)

(e) Merger of Oi and CorpCo shares, causing Oi to become a wholly-owned subsidiary of CorpCo. Each Oi common share will be exchanged for a CorpCo share and each Oi preferred share will be exchanged for 0.9211 CorpCo shares. The exchange ratios have been determined based on the quotations of Oi common shares and preferred shares over the 30-day period prior to the publication of the Material Fact Notice that disclosed the transaction and the direct or indirect stakes held by the companies involved in the transaction in Oi, under the premise that such companies will not have any liabilities or assets or will have sufficient cash or cash equivalents to fully settle their debts;

(f) Merger of Portugal Telecom with and into CorpCo. At the time of its merger with and into CorpCo, Portugal Telecom will have no material assets or liabilities other than its CorpCo shares or will have sufficient cash or cash equivalents to fully settle its debt;

(g) As a result of the steps described above, Portugal Telecom shareholders will receive a number of CorpCo shares equivalent to the number of CorpCo shares held by Portugal Telecom immediately before the merger referred to in the previous paragraph.

After the transaction is completed, CorpCo shares will be listed for trading on theNovo Mercado segment of the BM&FBOVESPA and on the NYSE Euronext Lisbon and the NYSE.

CorpCo will focus on operational excellence. A clear action plan has been prepared to integrate functions with an efficiency improvement potential. This includes identifying teams to capture synergies and address the current operational challenges.

On January 14, 2014, the Brazilian Antitrust Agency (Conselho Administrativo de Defesa Econômica, or CADE) approved the combination transaction of the activities and businesses of Oi and Portugal Telecom and on January 29, 2014 was the deadline for third parties to file any appeals against this agency’s decision or file a proceeding with the CADE Court. No appeals or proceedings against the decision were filed. Accordingly, CADE’s decision, published on January 14, 2014, was confirmed in all other respects.

Transfer of mobile towers

On December 3, 2013 the Company entered into an agreement with SBA Torres Brasil for the transfer of the shares representing 100% of the capital of one of the latter’s subsidiaries for approximately R$ 1.5 billion. Such subsidiary owns 2,007 telecommunications towers that are used to provide mobile de telephony services. This transaction should be completed by 2014.

30.SUBSEQUENT EVENTS

Merger of TNL PCS

On February 1, 2014, TNL PCS (Regions 1 and 3 mobile service operator) and Oi Móvel (Region 2 mobile service operator) held their Extraordinary Shareholders’ Meetings that approved the merger of the former with and into the latter, thus liquidating TNL PCS.

31.RECONCILIATION BETWEEN BRAZILIAN GAAP AND U.S. GAAP

31.1 – Description of GAAP differences:

The consolidated financial statements of the Company are prepared in accordance with accounting practices adopted in Brazil (“Brazilian GAAP”), which comply with those prescribed by Brazilian corporate law, the technical pronouncements, interpretations and orientations issued by the Accounting Pronouncements Committee (Comitê de Pronunciamentos Contábeis – CPC) and specific standards established by the Brazilian Securities Commission (CVM). Note 2 to the consolidated financial statements for the year ended December 31, 2013 summarizes the accounting policies adopted by the Company. Differences between those accounting policies and accounting policies generally accepted in the United States of America (“U.S. GAAP”), where applicable to Oi, are summarized below.

(a) Accounting treatment for the Restructuring

As mentioned in Note 1, the shareholders of the Oi companies (TNL, TMAR, Coari and Oi) approved at the shareholders’ meetings held on February 27, 2012 the corporate reorganization that consisted of the partial split-off of TMAR with the merger of the split-off portion by Coari followed by the merger of TMAR shares by Coari and the mergers of Coari and TNL with and into Oi, the company that now concentrates all the shareholdings in Oi companies and is the only Oi company listed in a stock exchange, and whose corporate name was changed to Oi S.A. at the time of the same shareholders’ meetings. Prior to this restructuring, TNL was the company that concentrated all the shareholdings in the Oi companies, including TMAR, which owned Coari that held a 49.3% interest in Brasil Telecom, S.A. (now Oi S.A.).

FASB ASC 805-50 establishes that the financial statements of the receiving entity, Oi S.A., shall report results of operations and other financial information for the period in which the transfer occurs as though the transfer of net assets or exchange of equity interests had occurred at the beginning of the period. In addition, U.S. GAAP also requires financial statements and other financial information presented to be retrospectively adjusted to furnish comparative information for all periods during which the entities were under common control, which for these purposes is since January 1, 2009.

Brazilian GAAP permits but does not require retrospective adjustment of the comparative financial information and to adjust its current reporting period before the date of the transaction, as if the combination had occurred before the start of the earliest period presented during which the entities were under common control. The effects of the corporate restructuring were applied prospectively from February 27, 2012 in Oi S.A.’s consolidated financial statements.

Furthermore, in accordance with Brazilian GAAP, the Company has accounted for the reverse mergers mentioned above using the carry-over basis of its own assets and liabilities and of the assets and liabilities assumed of TNL, Telemar and Coari as from the date of the reorganization. The carry-over basis of the assets and liabilities were determined at the lowest level entity in the group (i.e., the effects of the acquisition accounting relating to Coari’s acquisition of Brasil Telecom, now Oi S.A., were not reflected in the assets and liabilities of Oi S.A. in its consolidated financial statements as a result of the TNL merger).

Oi S.A. and Subsidiaries

Notes to the Financial Statements

for the Years Ended December 31, 2013, 2012 and 2011

(Amounts in thousands of Brazilian reais, unless otherwise stated)

In accordance with FASB ASC 805-50 – Business Combination – Related Issues, the assets and liabilities transferred between entities under common control are to be initially recognized by the receiving entity at the carrying amounts that were recorded in the financial statements of the parent company of the entities under common control, which is equivalent to apply the carry-over basis of the highest level entity in the group prior to the corporate reorganization.

Considering the requirements of FASB ASC 805-50, the Company presented as reconciling items between Brazilian and U.S. GAAP (a) the impact of including the assets, liabilities and results of operations of the entities involved in the corporate restructuring that were under common control prior to the restructuring referred to above using Brazilian GAAP historical amounts, and (b) the adjustments to reflect the acquisition accounting of BrT that were written off under Brazilian GAAP. The adjustments are comprised by: (1) the addition of Oi’s (former Brasil Telecom) TNL, TMAR and Coari assets, liabilities and results of operations prepared under Brazilian GAAP in order to reflect the effects of the corporate restructuring as if it had occurred at the earliest comparative period in which the entities were under common control; and (2) the recognition of the fair value adjustments recorded by Coari under the purchase price allocation of Brasil Telecom in 2009, which in accordance with Brazilian GAAP were fully reversed following the mergers occurred in February 2012 in Oi’s consolidated financial statements.

The table below presents the impacts of the fair value adjustments relating to the acquisition of Brasil Telecom as from February 29, 2012:

(b)Business combinations prior to January 1, 2009

As from January 1, 2010, companies in Brazil adopted a new set of accounting policies consistent with IFRS, which in relation to Oi’s business combinations occurred after January 1, 2009 are not materially different from US GAAP. Prior to this date, accounting for business combinations was not specifically addressed under Brazilian GAAP.

For all business combinations prior to January 1, 2009, the Company typically recognized the difference between the purchase price and the historical book value of the assets acquired and liabilities assumed as goodwill, which was amortized over the estimated period over which the Company expected to benefit from the goodwill. This period was determined based on the reasons attributed by management for the payment of goodwill. A test for impairment was made at least annually or if there is an indication that the unit in which the goodwill was allocated may be impaired.

Under U.S. GAAP, for the acquisitions of interests in Pegasus, Way-TV, Paggo and TNCP (Amazônia) that occurred prior to January 1, 2009, the Company adopted the procedures determined by FASB ASC 805 Business Combinations, resulting in a difference as compared to the Company’s accounting policy in force prior to that date. The accounting method used under U.S. GAAP in business combination transactions is the “purchase method”, which requires that acquirers reasonably determine the fair-value of the identifiable assets and liabilities of acquired companies, individually, to determine goodwill paid.

Under U.S. GAAP, goodwill represents the excess of cost over the fair value of the net assets of the business acquired. Goodwill and intangible assets acquired in a purchase business combination and determined to have an indefinite useful life are not amortized, but instead tested for impairment at least annually in accordance with the provisions of FASB ASC 350—Goodwill and Other Intangible Assets. FASB ASC 350 also requires that intangible assets with estimable useful lives be amortized over their respective estimated useful lives to their estimated residual values, and reviewed for impairment in accordance with FASB ASC 350.

Under FASB ASC 350, the Company evaluates goodwill for impairment by determining the fair value of each reporting unit and comparing it to the carrying amount of the reporting unit on a

Oi S.A. and Subsidiaries

Notes to the Financial Statements

for the Years Ended December 31, 2013, 2012 and 2011

(Amounts in thousands of Brazilian reais, unless otherwise stated)

yearly basis. To the extent the carrying amount of a reporting unit exceeds the respective fair value, the respective goodwill is considered to be impaired.

Reporting units

For U.S. GAAP purposes, the Company defines its reporting units, according to FASB ASC 280, as units comprising components with the same economic characteristics and which are reported together to the chief operating decision maker.

For U.S. GAAP purposes, the same way as for Brazilian GAAP, the Company’s management uses operating segment information for decision-making. The operating segments are identified according to the nature of the services and the technology used to provide the telecommunications services.

Fixed-line telephony/data: basically offers local and long distance voice transmission and data communication services;

Mobile telephony: offers primarily mobile voice, 3G data communication, and additional services, which include messaging services and interactivity; and

Other: includes the segment (i) internet service provider, whose revenue is mainly derived from Internet access services and online advertising, (ii) call center, whose revenue is mainly derived from third-party telemarketing services and customer service, (iii) TV, whose revenue is derived from pay TV services using both cable and DTH (Direct to home) technology, and (iv) means of payment, whose revenue is derived from accreditation and payment administration services using credit systems.

Under the terms of the operating concessions granted by the Federal Government, the Company is obliged to provide a certain minimum level of services over the entire area covered by its fixed-line operating licenses. Also, the Company does not possess discrete financial information that could allow a determination of assets and liabilities (and goodwill) allocation in a level below the entire fixed-line business segment and neither does it manage different areas of the concession as if they were separate businesses and has thus considered the entire fixed-line business to be one reporting unit. In viewing all of fixed-line assets and liabilities of the Company as one reporting unit and performing an initial assessment on this reporting unit as to whether there was an indication that goodwill is impaired, the second step of the impairment test was not required.

The Company was not required to recognize an impairment loss under US GAAP for any of the periods presented for any of its reporting units.

Acquisition of Pegasus

The Company acquired Pegasus in December 27, 2002. Under U.S. GAAP, of the difference amounting to R$253 million between the purchase price and the historical book value of the assets acquired and liabilities assumed, an amount of R$87 million was allocated to the data-transmission services reporting unit, since the acquisition of Pegasus generated a significant reduction in network maintenance costs for that reporting unit. The remaining portion in the amount of R$166 million was allocated to the fixed-line telecommunications services reporting unit, given that the acquisition

(Amounts in thousands of Brazilian reais, unless otherwise stated)

of Pegasus allowed the fixed-line telecommunications services reporting unit, to expand its corporate market share by offering data transmission services throughout Brazil on a nationwide basis.

Acquisition of Way-TV

The Company acquired Way-TV in November 2007. For U.S. GAAP purposes, all initial goodwill recorded under Brazilian GAAP, in the amount of R$64 million, was allocated to intangible assets, together with an amount of R$17 million, which under Brazilian GAAP is recorded as interest expense and for U.S. GAAP was included as part of the purchase price allocation. Under U.S. GAAP, the Company allocated R$56 million to the intangible asset “client base” and added R$25 million to the intangible asset “licenses”, which already existed on Way-TV’s balance sheet. The client base is amortized on a straight- line basis over the company’s churn rate of approximately 4 years and 6 months. The amount added to licenses is amortized over the remaining period of the licenses, which is 6 years and 10 months as of November 2007.

Acquisition of Paggo

The Company acquired Paggo in December 2007. For U.S. GAAP purposes, the initial goodwill recorded under Brazilian GAAP, in the amount of R$80 million, has been subject to fair value valuation but no intangible assets or fair value adjustments were identified, maintaining the same amount of goodwill under U.S. GAAP, which has been assigned to the reporting unit mobile telecommunications services.

In December 2011, following the completion of the sale of a 50% interest in this business, the Company recognized a U.S. GAAP adjustment of R$4 million relating to the gain on the sale that arose from the difference in the book value of the goodwill between Brazilian GAAP and U.S. GAAP on the date of sale.

(c)Pension plans and other post-retirement benefits

Under Brazilian GAAP, amounts due to a multi-sponsored pension plan are treated on an accrual basis when the obligations fall due. In December 1999, the Company split-up the Sistel multi-sponsored defined benefit plan and formed a single-sponsored defined benefit plan. However, the Company and the co-sponsors of the multi-employer pension plan agreed to jointly maintain a plan offering the current levels of benefits under Sistel for those employees who have retired before January 30, 2000. On September 21, 2000, the Company created a new defined contribution plan, which replaced the defined benefit plan by migrating active employees to the new plan. By the end of March 2001, the deadline for voluntary migrations, 96.0% of the active participants of the previous plan had migrated to the new defined contribution plan and the accrual of future benefits under the defined benefit plan relating to the post-retirement health care plan for these participants was eliminated. Under Brazilian GAAP, there was no requirement to recognize a gain or loss caused by a curtailment of a benefit plan. A summary of the actuarial position of plans which the Company sponsors, including the Company’s allocated assets and liabilities of multi-sponsored plans such as the PBS-A plan, is disclosed under Brazilian GAAP in the consolidated financial statements for the year ended December 31, 2013 (Note 25). If a plan has a positive funded status, which is not expected to generate future benefits, the company does not recognize the funded status, unless in case of express authorization for offsetting with future employer contribution.

Oi S.A. and Subsidiaries

Notes to the Financial Statements

for the Years Ended December 31, 2013, 2012 and 2011

(Amounts in thousands of Brazilian reais, unless otherwise stated)

Under U.S. GAAP, the Company applies FASB ASC 715—Retirement Benefits, which requires an employer to recognize the over- or under-funded status of a defined benefit postretirement plan as an asset or liability in its balance sheet and to recognize changes in that funded status in the year in which the changes occur through other comprehensive income. The Company measured the defined benefit plan assets and obligations as of the balance sheet date. For U.S. GAAP purposes, the differences between the fair value of the net pension obligation (assets) and the amount already recognized through the statement of income and the related deferred tax effects that were recorded as adjustments directly to shareholders’ equity have been considered as other comprehensive income.

To calculate the funded status of the plans, the provisions of FASB ASC 715 “Retirement Benefits” were applied with effect from January 1, 1992 because it was not feasible to apply them from the effective date specified in such provisions. For U.S. GAAP purposes the funded status of the pension plans is presented as a prepaid asset according to FASB ASC 715.

For U.S. GAAP purposes, unrecognized net gain or losses are recognized following the “corridor” approach, i.e. the portion which exceeds 10% of the greater of the projected benefit obligation or the market-related value of plan assets is recognized, and the unrecognized prior service cost or benefit and unrecognized transition obligation are deferred according to the actuarial valuation. In accordance with Brazilian GAAP, the Company adopted the standard CPC 19 (R2) that requires net actuarial losses and gains to be recognized directly to shareholders’ equity in the period they occur.

U.S. GAAP do not require the sponsor to record actuarial calculations for multi-sponsored pension plans such as the PBS-A and contributions to such plans are recorded on an accrual basis. For U.S. GAAP purposes, refunds from these plans are recorded only upon the cash receipt.

In 2007, the Company made a payment in the amount of R$260 million to cover the increase in future contributions to the pension plan, due to changes in the actuarial assumptions. This amount was recorded as prepaid expenses under Brazilian GAAP, while under U.S. GAAP was recognized directly in earnings. Consequently, as from that date, the amortization of this prepaid expense under Brazilian GAAP is reversed for U.S. GAAP purposes.

(d)Capitalized interest

Until December 31, 1993, capitalized interest was not added to the individual assets in property, plant and equipment; instead, it was capitalized separately and amortized over a period different from the estimated useful lives of the related assets. Under U.S. GAAP, capitalized interest is added to the individual assets and is amortized over their estimated useful lives.

Also, under Brazilian GAAP, as applied to companies in the telecommunications industry, interest attributable to construction in-progress was calculated, up to December 31, 1998, at the rate of 12% per annum of the balance of construction-in-progress and that part which related to interest on third party loans was credited to interest expense based on actual interest costs with the balance relating to self- funding being credited to capital reserves. Starting 1999, Brazilian Corporate Law required capitalization of interest on loans specifically related to financing of construction in progress, and interest on self- financing is no longer allowed.

Oi S.A. and Subsidiaries

Notes to the Financial Statements

for the Years Ended December 31, 2013, 2012 and 2011

(Amounts in thousands of Brazilian reais, unless otherwise stated)

Starting January 1, 2009, in accordance with Brazilian GAAP, financial charges on obligations financing assets and construction works in progress are capitalized, including interest expenses and certain foreign exchange differences. Under U.S. GAAP, the Company capitalizes only interest expenses to the extent that borrowings do not exceed the balances of construction in-progress, as generally foreign exchange differences are not eligible for being recorded as part of the cost of the asset.

(e)Income tax and social contribution

The differences identified between Brazilian and U.S. GAAP regarding income taxes relate to the tax effects on the remaining adjustments included in the reconciliations of net income and shareholders’ equity. These differences are presented in the reconciliations under the line items “Deferred tax on above adjustments”, except for the adjustments relating to the accounting treatment of the combined entity (Note 31.1.a) which are presented net of the related tax effect. In addition, under Brazilian GAAP deferred taxes are classified entirely as non-current, while under U.S. GAAP deferred taxes are classified between current and non-current.

(f)Valuation of long-lived assets

FASB ASC 360 - Property, Plant and Equipment provides a single accounting model for the disposal of long-lived assets. FASB ASC 360 also changes the criteria for classifying an asset as held for sale; and broadens the scope of businesses to be disposed of that qualify for reporting as discontinued operations and changes the timing of recognizing losses on such operations. In accordance with FASB ASC 360, long-lived assets, such as property, plant, and equipment, and purchased intangibles subject to amortization, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to estimated undiscounted future cash flows expected to be generated by the asset. If the carrying amount of an asset exceeds its estimated future cash flows, an impairment charge is recognized by the amount by which the carrying amount of the asset exceeds the fair value of the asset. Assets to be disposed of would be separately presented in the balance sheet and reported at the lower of the carrying amount or fair value less costs to sell, and are no longer depreciated. The assets and liabilities of a disposed group classified as held for sale would be presented separately in the appropriate asset and liability sections of the balance sheet.

Brazilian GAAP requires an assessment which is performed annually or whenever events or changes in circumstances indicate that the carrying amount of an asset or group of assets may not be recoverable. For all periods presented, no impairment losses were recognized under Brazilian GAAP and U.S. GAAP.

(g)Recent U.S. GAAP accounting standards updates

In February 2013, the FASB issued Accounting standard update No. 2013-02 regarding Other Comprehensive Income (Topic 220), which supersede and replace the presentation requirements for reclassifications out of accumulated other comprehensive income in ASUs 2011-05 (issued in June 2011) and 2011-12 (issued in December 2011) for all public and private organizations. The amendments would require an entity to provide additional information about reclassifications out of accumulated other comprehensive income and will increase the disclosures to be provided by the

Notes to the Financial Statements

for the Years Ended December 31, 2013, 2012 and 2011

(Amounts in thousands of Brazilian reais, unless otherwise stated)

For the year ended December 31, 2013, total valuation allowance increased from R$155 million to R$224 million as of December 31, 2013, reflecting unrecognized temporary differences generated in 2013, amounting to R$94 million, net of prior year unrecognized temporary differences that were recorded in 2013, amounting to R$26 million. It is more likely than not that the results of future operations will generate sufficient taxable income to realize the deferred tax assets.

The tax loss carryfowards of approximately R$ 2,831 million do not expire, and may be carried forward indefinitely.

We recognize the financial statement effects of a tax return position when it is more likely than not, based on the technical merits, that the position will ultimately be sustained. For tax positions that meet this recognition threshold, we apply our judgment, taking into account applicable tax laws, our experience in managing tax audits and relevant GAAP to determine the amount of tax benefits to recognize in our financial statements.

The company and its subsidiaries file income tax returns in all jurisdictions in which they do business (Brazil is the only relevant 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. All audit periods prior to 2009 are closed for federal examination purposes.

As of December 31, 2013 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 General and administrative expenses, respectively.

(h)Description of investment policies and strategies

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, 20132015 consists mainly of the following portfolio: 80%91% in debt securities, 8%5% in equity of Brazilian companies and 1%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 also 80%88% of the portfolio in December 31, 2013.2015.

The investment policies and strategies for BrTPREV, TCSPREV and PAMEC, is described in Investment Policy, which is approved annually by the pension fund’s board. Itboard 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.

The average ceilings set for the different types of investment permitted for pension funds are as follows:

(b)Employee profit sharing

In the year ended December 31, 2015, the Company and its subsidiaries recognized provisions for employee profit sharing based on individual and corporate goal attainment estimates totaling R$70,199 in Company and R$210,054 on a consolidated basis.

(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 Law 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. We 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. This share-based compensation program has been recorded as a liability in the consolidated financial statements. No relevant provisions were recorded in 2015 considering the Company performance.

24.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: Mobile Telecommunications Limited in Namibia, 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:

The balances and transactions with joint venture, associates, and unconsolidated entities result from business transactions carried out in the normal course of operations, namely the provision of telecommunications services by the Company to these entities and the acquisition of these entities’ contents and the rent of their infrastructure.

Compensation of key management personnel

The compensation of the officers responsible for planning, managing and controlling the Company’s activities, i.e., directors and executive officers, totaled R$25,441 (R$25,409 at December 31, 2014) in the Company and R$25,649 (R$25,565 December 31, 2014) on a consolidated basis.

26.HELD-FOR-SALE ASSETS AND DISCONTINUED OPERATIONS

Sale of PT Portugal shares to Altice

On December 9, 2014, the Company and Altice entered into a purchase and sale agreement of all PT Portugal shares to Altice, basically involving the operations conducted by PT Portugal in Portugal and in Hungary.

On January 22, 2015, Pharol shareholders approved the sale by Oi of all PT Portugal shares to Altice, under the terms and conditions of the Share Purchase and Sale Agreement. Accordingly, the suspensive condition provided for in said agreement to its effectiveness was implemented.

On June 2, 2015, the sale by Oi to Altice of its entire stake in PT Portugal was completed. Altice Portugal paid a total of €5,789 million for PT Portugal, of which €4,920 million were received in cash by Oi and €869 million were immediately allocated to settle PT Portugal euro-denominated debt. There is also a provision for the payment of an earn-out of €500 million related to PT Portugal’s future generation of revenue and Oi provided a set of guarantees and representations usual in this type of agreements to the buyer.

Classification of the investment sales transactions as discontinued operations

On May 5, 2014, the Company acquired PT Portugal and since then it also fully consolidated its profits or losses, assets and liabilities. In December 2014, with the approval of the sale of the investments in PT Portugal to Altice, the Company classified its operations in Portugal as held-for-sale assets and liabilities, and discontinued operations.

With the sale of PT Portugal shares to Altice, the loss on divesture is presented as discontinued operations in a single line of the income statement, as follows:

The final price is subject to possible post-closing adjustments to be determined in the following months based on changes in the cash, debt, and working capital positions at the closing date.

(iv)The profit or loss from discontinued operations includes the effect of taxes amounting to R$327,115 (R$92,545 in 2014).

Approval of preparatory actions for the sale of Africatel

At the Board of Directors’ meeting held on September 16, 2014, Oi’s management was authorized to take all the necessary actions to divest Oi’s stake in Africatel, representing 75% of Africatel’s share capital, and/or dispose of its assets. Oi will lead the sale process, even though we believe 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 holds the remaining 25% of Africatel’s share capital. Oi is 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, our indirect subsidiary Africatel GmbH & Co. KG (“Africatel GmbH”), direct holder of the Oi’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 require Africatel GmbH to acquire its shares in Africatel.

Oi S.A. and Subsidiaries

Notes to the Financial Statements

for the years ended December 31, 2015, 2014 and 2013

(In thousands of Brazilian reais - R$, unless otherwise stated)

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 intends to challenge the exercise of this put option by Samba Luxco in the current circumstances, which, pursuant to Africatel’s shareholders’ agreement, which was duly notified in Africatel GmbH’s reply to Samba Luxco’s letter, on September 26, 2014.

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 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 GmbH submitted their Statement of Defence. On January 25, 2016, Samba Luxco submitted its Reply and, on March 14, 2016, Pharol and Africatel GmbH submitted their Rejoinder.

The proceedings have been bifurcated, with the merits hearing currently scheduled to take place during November 2016. Dates for a quantum hearing (if necessary) have been reserved in March 2017.

With regard 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. 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 anon-controlling interest in Africatel to Samba Luxco in 2007 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 anon-controlling stake in Africatel to Samba Luxco.

The assets and liabilities of the African operations are stated at the lower of their carrying amounts and their fair values less costs to sell.

The African operations are consolidated in the income statement since May 5, 2014.

The main components of the assets for held sale and liabilities associated to assets held for sale of the African operations are as follows:

(i)Refers to dividends receivable from Unitel. In 2015, the Company’s recognized dividends not yet received based on the expected recoverable amount and took into account, for this valuation, the existence of lawsuits filed to collect these amounts, the expected favorable decisions on these lawsuits, and the existence of cash at Unitel for the payment of these dividends. The dividends not paid by Unitel to PT Ventures refer to fiscal years 2010, 2011, 2012, and 2013, totaling US$661million;
(ii)Refers mainly to the fair value of the indirect interest financial investment of 18.75% of Unitel’s share capital, classified as held for sale. The fair value of this investment at the date of acquisition was estimated based on the valuation made by Banco Santander (Brasil), which used a series of estimates and assumptions, including cash flows forecasts for a four-year period, the choice of a growth rate to extrapolate the cash flows projections, and definition of appropriate discount rates. The Company has the policy of monitoring and periodically updating the main assumptions and material estimates used in the fair value measurement, and also takes 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. As at December 31, 2015 and in the context of the updating of assumptions referred to above, the Company determined a fair value of the investment in Unitel of R$3,436 million and recognized in profit or loss a loss of R$408 million. The Company believes that the fair value measured under the Discounted Cash Flows method and using the discount rate assumptions (from 15.5% to 17.5%), foreign exchange rates, and other Angolan official financial indicators, corresponds to the best estimate of the realizable value of the investment in Unitel.
(iii)As at December 31, 2015, the Company conducted the annual impairment test of its assets related to the operations in África and recognized a loss on goodwill amounting to R$89,176.

27.OTHER INFORMATION

(a)Rio Forte securities

On June 30, 2014, the Company was informed, through a notice disclosed by Pharol, of the investment made by PT International Finance BV (“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.

Notes to the Financial Statements

for the years ended December 31, 2015, 2014 and 2013

(In thousands of Brazilian reais - R$, unless otherwise stated)

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 matures in July 2014 and subsequently 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 investments made in Rio Forte commercial papers

On September 8, 2014, after obtaining the due corporate approvals, the Company, the 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 shares 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 Pharol (“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 Call 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 Call Option agreements.

On March 31, 2015, the Company announced, the consummation of the Exchange, under which Pharol delivered to the Oi Subsidiaries Oi unencumbered 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 cash 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). Oi shares received by PTIF as a result of the Exchange will remain in 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, and amended on March 31, 2015, the call option on Oi shares granted Pharol 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 percentages below:

(ii) Exercise Price: R$1.8529 per Company preferred share and R$2.0104 per Company common share, before the reverse share split approved on November 18, 2014, as adjusted by the interbank deposit rate (CDI), plus 1.5% per annum, calculated on a pro rata temporis basis, from the date of the Exchange to the date of the effective payment of each exercise price, in whole or in part, of the Option. The exercise price of the shares will be paid in cash, at the transfer date of the Shares Subject to the Option.

Oi is not required to maintain the Exchanged Shares in treasury. In the event that PTIF or any of Oi’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 the 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 is 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

Oi S.A. and Subsidiaries

Notes to the Financial Statements

for the years ended December 31, 2015, 2014 and 2013

(In thousands of Brazilian reais - R$, unless otherwise stated)

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 14 of the Shares Subject to the Option, and Pharol can freely use the 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 only be 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, 2015, the fair value of the Call Option is estimated at R$4 million calculated by the Company using theBlack-Scholes model and theoretical share volatility assumptions, using the Revenue Approach valuation technique.

(b)Consolidation of the telecommunications industry in the Brazilian market

On August 26, 2014, Oi entered into an agreement with Banco BTG Pactual S.A. (“BTG Pactual”) under which the latter will act as commissioner to develop feasible alternatives to render viable participating in the industry consolidation in the Brazilian telecommunications market. As already reported to the market, BTG Pactual held discussions with third parties regarding a possible transaction and the role of BTG Pactual includes contracting other market players that could be interested in the transaction, as Company agent for the transaction.

On October 23, 2015, the company received from LetterOne Technology (UK) LLP, one of the companies in the Letter One investment group (“L1 Technology”), a letter containing an exclusivity proposal in a potential transaction for the specific purpose of allowing a consolidation in the Brazilian telecommunications industry involving a potential business combination with TIM Participações S.A. (“TIM Participações”). Under the proposal, L1 Technology would be willing to

Oi S.A. and Subsidiaries

Notes to the Financial Statements

for the years ended December 31, 2015, 2014 and 2013

(In thousands of Brazilian reais - R$, unless otherwise stated)

make a capital contribution of up to US$4.0 billion to the Company, contingent to the consolidation transaction.

After assessing the proposal, the Company sent to counter-proposal to L1 Technology on October 28, de 2015, under which Oi and L1 Technology would mutually grant each other an exclusivity right over a seven-month periods, starting on October 23, 2015, especially regarding business combinations involving telecommunications companies or telecommunications assets in Brazil. Since L1 Technology accepted the terms of the counterproposal, Oi and L1 Technology are now bound by the exclusivity agreement during the seven-period starting October 23, 2015.

If the transaction under construction materializes, it is expected a decrease in Oi’s leverage to become a more robust player, and the generation of major synergies and gains of scale, promoting the creation of value for all shareholders. A potential union of Oi with TIM Participações should result in the incorporation of a more complete, better-positioned operator, capable of competing with global players already operating in Brazil. Consumers should benefit from this trend, consequently strengthening the Company.

On February 25, 2016, Oi disclosed a Material Fact Notice where it informed that it has been notified by L1 Technology that L1 Technology had disclosed a notice stating that it had been informed by TIM that the latter was no longer interested in proceeding with the negotiations on the possibility of a business combination with Oi in Brazil. L1 Technology informed that without TIM’s involvement it could not proceed with transaction as previously planned. In light of this information, Oi will assess the impacts of this notice on the possibilities of consolidation in the Brazilian market.

(c)Completion of the share auction

The last auction to sell the shares resulting from the reverse split of share fractions approved by the shareholders at Extraordinary Shareholders’ Meeting held on November 18, 2014 was held on June 30, 2015.

As a result of the three auctions held, 1,069,131 Company common shares and 1,162,652 Company preferred shares were sold (“Share”), representing all the shares resulting from the reverse split of share fractions.

The net proceeds of the sale of the Shares totaled R$13,632 and were deposited on July 10, 2015 on behalf of the share fraction holders, proportionately to the number of shares held.

(d)New York Stock Exchange (NYSE) Listing Rule

In September 2015, the Company was notified by the NYSE that Oi was not complying with the continued listing rule, which requires that the average closing price of the listed securities of a company cannot go below US$1.00 per share in any consecutive30-day trading period.

On January 22, 2016, in order to comply with the minimum share price requirement established by NYSE, Oi disclosed a Notice to the Market announcing the change in Company’s common shares

ratio of the Depositary Receipts Program, Level II, Sponsored (“Common DR”) so that each Common DR, which was previously one (1) common share, represents five (5) common shares as from February 1, 2016.

28.SUBSEQUENT EVENTS

Optimization of the Company’s liquidity and debt profile

The Company has retained PJT Partners as financial advisor to assist Oi in evaluating financial and strategic alternatives to optimize its liquidity and debt profile. In addition on April 25, 2016, the Company announced that it has entered into a customary non-disclosure agreement with an advisor to a diverse ad hoc group of holders of the bonds issued by the Company and certain of its affiliated companies, as an initial step toward discussions regarding the terms of a potential restructuring.

Oi’s operating and business focus remains unchanged and Oi is still committed to continuing to make investments that ensure a continual improvement of its quality of service, which it believes will allow it to continue to bring technological advances to its customers all over Brazil. Oi also continues to undertake efforts for the operating upgrading and transformation of its business by focusing on austerity, infrastructure optimization, process revision, and sales actions.

Debenture holders’ general meeting of the 5th and the 9th Issuance of the Company’s Debentures

On April 15, 2016, general debenture holders’ meetings were held for: (i) the 5th Issue of Unsecured, Nonconvertible Public Debentures (“5th Issue”); and (ii) the 9th Issue of Simple, Unsecured, Nonconvertible Debentures in up to Two Series, for Public Distribution (“9th Issue” and collectively with the 5th Issue, “Debentures”), both issued by the Company (“GDMs” or individually “5th Issue GDM” and “9th Issue GDM”).

Contrarily to the 8th and 10th issues of debentures, where the Company obtained a waiver on the calculation of the leverage ratio, the same waiver was not granted for the Debentures. Since the Company did not comply with this financial ratio for the Debentures, the related fiduciary agents called the GDMs.

With regard to the 5th Issue, the minimum quorum to open the GDM was not reached and the 5th Issue fiduciary agent published, on April 19, 2016, a second call of said meeting for April 27, 2016, which did not reach the minimum quorum either. Pursuant to the debenture indenture, the fiduciary agent declared the accelerated maturity of the outstanding debentures, resulting in the repayment of R$1,519,961.56.

With regard to the 9th Issue, the fiduciary agent declared the accelerated maturity of the outstanding debentures pursuant to Clause 6.23 of the 9th Issue debenture indenture, resulting in the repayment of R$21,518,990.58 at April 20th, 2016.
